Anatomy and Physiology Ch. 1 Study Guide Essay

Anatomy the study of the form or structure and governance of soundbox split and their relationshipsPhysiology the study of the functions of the form parts or structures and their relationships in conserveinglife processes.Levels of Structural OrganizationThe human body consists of levels of structural institution that be associated with one another.There are six levels of structural giving medicationI. chemical level It is the simplest level and it includes all of the chemical substances es displaceial for maintaining life. These substances are made up of atoms.An atom is thesmallest unit of matter. Matter is anything that takes up infinite and has mass.Atoms combine to form molecules, which whitethorn be simple orcomplex. distinct types of molecules combine to form oranelles (little organs). Organelles are unique(predicate) structures that carry out unique(predicate) functions.2. cellular level The cell is the staple fiber unit of structureand function and of life. Cells vary in size, shape, and function and may contain many types of organelles.3. create from raw material level Tissues are groups of similar cells thatserve a specific function.There are four major types of tissues in the human bodya.epithelial tissue It is found lining bodycavities and covers the surface of the body.It functions inprotection, secretion, and excretion.b. connective tissue It is found on the surfaces ofand in organs and tissues and functions in protection, support, and attaching organs and tissues to each other and to the protects of body cavities.c. vimman tissue It functions in the heading ofbody parts and organs, and in the movement of substancesthroughout the body.There are tercet major types of muscle tissue(1)skeletal muscle It is found attached to andcovering bones and it functions in bodymovement.(2)cardiac muscle It is located in the heartwall and functions in the contraction andrelaxation of the heart as it beats.(3)smooth muscle It is loc ated in the walls of inbred or visceral organs and it functionsin moving substances throughout the body.d.nervous tissueIt is located in the champion and spinal cord, and extends to various tissues and organs.Itfunctions in transmitting electrical or gist impulses from the external and internal environments to the brain and spinal cord where it is interpreted and a response occurs.4. organ level Organs are groups of two or more types oftissue working together to behave a specific function.5. organ strategy level sTstems are groups of organsthat work virtually together to perform a common function.There are eleven organ systems in the human bodyaog.h.i.j.k.integumentary system tendinous systemskeletal systemnervous systemendocrine systemcardiovascular systemlymphatic systemrespiratory systemdigestive systemurinary systemreproductive system6. organismal level It is the highest level of structuralorganization and it consists of groups of organ systems working together to main tain body structure and function. Organ systems work together to maintain an internal environment that is fairly constant, stable, or balanced. This is referred to as homeostasis (to stay the same). Changes do occur, but within very narrow ranges or limits.HomeostasisBody parts or structures function efficiently in maintaining metabolic processes and when the survival unavoidably are within certain limits or optimum levels.The survival needfully includewater,oxyqen, nutrients, an appropriate bod temperature, and atmospheric pressure. Water is necessary for chemical reactions, excretion, and secretion.Oxyqen is required for many of the metabolicreactions that break down nutrients and earmark energy. Nutrients provide energy for cells and cell processes. Bod temperature must be maintained within a certain range for chemical reactions and cell processes to perform efficiently.If the body temperature falls too low or increases too high, chemical reactions go away slow down or may s top. Atmospheric pressure is the office of air on the body surface by the weight of air. It is substantial in breathing and in the exchange of oxygen and carbon dioxide in the lungs. To maintain homeostasis there are control mechanisms. Control mechanisms consist of three partsi. receptor It responds to sensory stimulifrom theinternal and external environments. The information is sent along afferent pathways to the control center.2. control center It consists of the brain and spinal cord which interpret and analyze the information and determine an appropriate response. nurture is then sent along efferentpathways to the effector.3. effector It consists of tissues, organs, or glands that perform a motor response to the original remark that was received by the receptor. The response involves a feedback mechanism. If the response slows down or inhibit the stimulus it is a neqative feedback mechanism. If the response speeds up or enhances the stimulus, it is a positive feedback mec hanism. most(prenominal) controlmechanisms for homeostasis in the human body are negative feedback mechanisms.

Lamb: The Gospel According to Biff, Christ’s Childhood Pal Chapter 7

Chapter 7And the n mavensuch verbalize, What prophet has this written? For in this book is foret hoary either the events which sh solely induce to give in the next week in the land of Days of Our Lives and All My Children.And I said to the holy person, You fabulously feebleminded bundle of f tucker outhers, in that locations no prophet involved. They cognise what is going to hand because they write it alone smooth in advance for the actors to actualize.So it is written, so it sh either be do, said the apotheosis.I crossed the room and sat on the edge of the bed next to Raziel. His inspect never wavered from his Soap opera house Digest. I pushed the magazine wad so the angel had to olfactory property me in the stage.Raziel, do you remember the meter in the first place mankind, the time when in that location were secure now the paradisely host and the Lord?Yes, those were the best of times. Except for the war, of course. sole(prenominal) opposite than tha t, yes, wonderful times.And you angels were as strong and beautiful as inspired imagination, your voices sing praise for the Lord and his glory to the ends of the universe, and yet the Lord saw see to create us, mankind, weak, twisted, and profane, right?Thats when it all started to go d avowhill, if you withdraw me, Raziel said.Well, do you eff why the Lord decided to create us?No. Ours is non to question the Will.Because you be all dumbfucks, thats why. Youre as mindless as the machinery of the stars. saints ar just pretty insects. Days of Our Lives is a show, Raziel, a play. Its non real, pass it?No.And he didnt. Ive learned that t presents a tradition in this time of disuniteing funny stories ab surface the stupidity of quite a little with yellow h circulate. cypher where that started.I conjecture that we all expected everything to go tooshie to general aft(prenominal) the killer was found, exactly it seemed that the popishs were much more concerned with the defunctness of the Sicarii then(prenominal) they were with a single resurrection. To be fair, I demand to word that resurrections werent that uncommon in those age. As I manpowerti unmatchabled, we Jews were quick to amount our bloodless into the ground, and with speed, theres bound to be errors. Occasionally nearly poor soul would string up unconscious during a fever and set off to find himself being clad in linen and prepared for the grave. But funerals were a prudish itinerary to get the family together, and there was always a fine meal after(prenominal)ward, so no one genuinely complained, except perhaps those people who didnt wake before they were buried, and if they complained well, Im sure God hear them. (It paid to be a light sleeper, in my time.) So, impressed as they office boast been with the paseo dead, the next day the romishs began to round up suspected conspirators. The men in Maggies family were hau take off to Sepphoris at dawn.No miracles would come to take away ab kayoed the unloose of the prisoners, still neither were there all crucifixions announced in the days that followed. After two weeks had passed with no word of the fate or check into of the men, Maggie, her m or so other, her aunts, and her siss went to the synagogue on the Sabbath and assemblinged to the Pharisees for help.The next day, the Pharisees from Nazareth, Japhia, and Sepphoris appeared at the roman print garrison to appeal to Justus for the release of the prisoners. I dont know what they said, or what sort of leverage they could possibly imbibe used to move the Romans, only the following day, just after dawn, the men of Maggies family staggered back into our village, beaten, starving, and c everywhereed with filth, but very much alive.t contacther was no feast, no celebration for the return of the prisoners we Jews walked softly for a a few(prenominal)er months to allow the Romans to settle d suffer. Maggie seemed distant in the weeks t hat followed, and taunt and I never saw the grinning that could make the tinge catch in our throats. She seemed to be avoiding us, rushing out of the square whenever we saw her there, or on the Sabbath, staying so close to the women of her family that we couldnt talk to her. Finally, after a month had passed, with absolutely no regard for custom or common courtesy, baitua insisted that we skip work and dragged me by the sleeve to Maggies house. She was kneeling on the ground outside the door, abrasion some barley with a millstone. We could see her mother moving some in the house and hear the sound of her military chaplain and of age(p) sidekick Simon (who was called Lazarus) works the forge next door. Maggie seemed to be lost in the rhythm of grinding the grain, so she didnt see us approach. banterua set up his hand on her shoulder, and without experience up, she smiled.You are supposed to be building a house in Sepphoris, she said.We thought it more important to visit a sick friend.And who would that be?Who do you mobilize?Im non sick. In fact, Ive been healed by the stimulate of the christ.I think non, said baitua.She at long last looked up at him and her smile evaporated. I cant be friends with you two anymore, she said. Things have changed.What, because your uncle was a Sicarii? I said. Dont be silly.No, because my mother make a bargain to get Iban to convince the other Pharisees to go to Sepphoris and plead for the mens lives.What kind of bargain? teaseua asked.I am betrothed. She looked at the millstone again and a tear dripped into the powdered grain.We were some(prenominal) stunned. Josh took his hand from her shoulder and stepped back, then looked at me as if there was something I could do. I felt as if I would start instantaneous at any second myself. I managed to choke out, Who to?To Jakan, Maggie said with a sob.Ibans son? The creep? The bully?Maggie nodded. Joshua covered his mouth and ran a few steps away, then threw up. I was tempted to join him, but instead I crouched in front of Maggie.How long before youre marry?Im to be married a month after the Passover feast. Mother made him wait hexad months.Six months Six months Thats forever, Maggie. Why, Jakan could be killed in a thousand grievous ways in sextet months, and thats just the ones I can think of right now. Why, individual could turn him in to the Romans for being a rebel. Im non opineing who, but someone might. It could happen.Im sorry, sluggard.Dont be sorry for me, why would you be sorry for me?I know how you feel, so Im sorry.I was thrown for a second. I glanced at Joshua to see if he could give me a clue, but he was still absorbed in splattering his breakfast in the dirt.But its Joshua who you love? I finally said.Does that make you feel any better?Well, no.Then Im sorry. She made as if to reach out to touch my cheek, but her mother called her before she made contact.Right now, Mary, in this houseMaggie nodded toward the barfing Me ssiah. Take kick of him.Hell be fine.And take care of yourself.Ill be fine too, Maggie. Dont forget I have an emergency backup wife. Besides, its sixsome months. A draw can happen in six months. Its non analogous we wont see you. I was onerous to sound more shining than I felt.Take Joshua home, she said. Then she quickly kissed me on the cheek and ran into the house.Joshua was all in all against the idea of murdering Jakan, or even praying for harm to come to him. If anything, Joshua seemed more companion commensurate disposed toward Jakan than he had been before, going as far as to explore him out and congratulate him on his betrothal to Maggie, an act that left me effect angry and betrayed. I confronted Joshua in the olive orchard, where he had gone to pray among the twisted tree trunks.You coward, I said, you could strike him down if you wanted to.As could you, he replied.Yeah, but you can call the wrath of God down upon him. Id have to sneak up behind him and brain him with a rock. Theres a difference.And you would have me kill Jakan for what, your bad luck?Works for me.Is it so fleshy for you to give up what you never had?I had hope, Josh. You understand hope, dont you? Sometimes he could be mightily dense, or so I thought. I didnt make take how much he was hurting inside, or how much he wanted to do something.I think I understand hope, Im just not sure that I am allowed to have any.Oh, dont start with that Everyone gets something but me speech. Youve got plenty.Josh wheeled on me, his eyeball like fire, Like what? What do I have?Uh I wanted to say something close a truly sexy mother, but that didnt seem like the sort of thing he wanted to hear. Uh, you have God.So do you. So does everyone.Really?Yes.not the Romans.There are Roman Jews.Well, youve got, uh that healing-raising-the-dead thing.Oh yeah, and thats working really well.Well, youre the Messiah, whats that? Thats something. If you told people you were the Messiah theyd have to do what you say.I cant tell them.Why not?I dont know how to be the Messiah.Well, at least do something about(predicate) Maggie.He cant, came a voice from behind a tree. A golden send emanated from either side of the trunk.Whos there? Joshua called.The angel Raziel stepped out from behind the tree.Angel of the Lord, I said under my clue to Josh.I know, he said, in a you seen one, you seen em all way.He cant do anything, the angel repeated.Why not? I asked.Because he may not know any woman.I may not? Joshua said, not sounding at all happy.He may not in that he should not, or that he cannot? I asked.The angel scratched his golden gaffer, I didnt think to ask.Its kind of important, I said.Well, he cant do anything about Mary Magdalene, I know that. They told me to come and tell him that. That and that it is time for him to go.Go where?I didnt think to ask.I suppose I should have been stir, but I seemed to have passed right through frightened to exasperated. I stepped up to the ange l and poked him in the chest. are you the same angel that came to us before, to announce the approach path of the messiah?It was the Lords exit that I bring that joyful news.I just wondered, in case all of you angels look alike or something. So, after you showed up ten years late, they move you with another(prenominal) message?I am here to tell the Savior that it is time for him to go.But you dont know where?No.And this golden stuff around you, this light, what is this?The glory of the Lord.Youre sure its not stupidity leaking out of you?Biff, be tenuous, he is the messenger of the Lord.Well, hell, Josh, hes no help at all. If were going to get angels from heaven they should at least know what they are doing. Blow down protects or something, destroy cities, oh, I dont know get the whole message.Im sorry, the angel said. Would you like me to destroy a metropolis?Go find out where Josh is supposed to go. How bout that?I can do that.Then do that.Ill be right back.Well wait.Gods peed, Joshua said.In an instant the angel moved behind another tree trunk and the golden glow was gone from the olive grove with a warm breeze.You were sort of hard on him, Joshua said.Josh, being nice isnt always going to get the job done.One can try.Was Moses nice to Pharaoh?Before Joshua could answer me, the warm breeze blew into the olive grove again and the angel stepped out from behind a tree.To find your part, he said.What? I said.What? Joshua said.You are supposed to go find your destiny.Thats it? Joshua said.Yes.What about the knowing a woman thing? I asked.I have to go now.Grab him, Josh. You collar him and Ill hit him.But the angel was gone with the breeze.My destiny? Joshua looked at his open, renounce palms.We should have pounded the answer out of him, I said.I dont think that would have worked.Oh, back to the nice strategy. Did Moses Moses should have said, Let my people go, entertain.That would have made the difference?It could have worked. You dont know.So what do you do about your destiny?Im going to ask the consecrated of Holies when we go to the Temple for the Passover.And so it came to pass that in the spring all of the Jews from Galilee made the pilgrimage to Jerusalem for the Passover feast, and Joshua began the count for his destiny. The avenue was lined with families making their way to the holy city. Camels, carts, and donkeys were loaded superior with provisions for the trip, and all along the column of pilgrims you could hear the bleating of the lambs that would be sacrificed for the feast. The road was dry that year, and a red-brown cloud of dust wound its way over the road as far as one could see in either direction.Since we were each the eldest in our families, it fell on Joshua and me to grasp track of all our younger brothers and sisters. It seemed that the easiest way to accomplish this was to tie them together, so we strung together, by height, my two brothers and Joshs three brothers and two sisters. I fasten the r ope loosely around their necks so it would only choke them if they got out of line.I can untie this, said James.Me too, said my brother Shem.But you wont. This is the part of the Passover where you reenact Moses leading you out of the Promised Land, you have to stay with the microscopic ones.Youre not Moses, said Shem.No no, Im not Moses. Smart of you to notice. I tied(p) the end of the rope to a nearby wagon that was loaded situated-back with jars of wine. This wagon is Moses, I said. Follow it.That wagon isnt Its symbolic, shut the hell up and follow Moses.Thus freed of our responsibilities, Joshua and I went looking at for Maggie and her family. We knew that Maggie and her clan had left after us, so we fought backward through the pilgrims, braving donkey bites and camel spit until we spotted her august blue shawl on the hill behind us, perhaps a half-mile back. We had obdurate to just sit by the side of the road to wait until she reached us, or else than battle the crow d, when unawares the column of pilgrims started to leave the road altogether, moving to the sides in a great wave. When we saw the red crest of a centurions helmet come over the top of the hill we understood. Our people were making way for the Roman army. (There would be nearly a million Jews in Jerusalem for Passover a million Jews celebrating their liberation from oppression, a very dangerous mix from the Roman point of view. The Roman governor would come from Caesarea with his full legion of six thousand men, and each of the other barracks in Judea, Samaria, and Galilee would send a degree Celsius or two of soldiers to the holy city.)We used the opportunity to dash back to Maggie, arriving there at the same time as the Roman army. The centurion that led the cavalry kicked at me as he passed, his hobnail boot lacking(p) my head by a hairs breadth. I suppose I should be glad he wasnt a standard-bearer or I might have been conked with a Roman eagle.How long do I have to wait bef ore you drive them from the land and restore the kingdom to our people, Joshua? Maggie stood there with her pass on her hips, trying to look stern, but her blue eyeball betrayed that she was about to burst into laughter.Uh, shalom to you too, Maggie, Joshua said.How about you, Biff, have you learned to be an nitwit yet, or are you behind in your studies? Those laughing eyes, even as the Romans passed by only an arms length away. God, I miss her.Im learning, I said.Maggie put down the jar shed been carrying and threw her arms out to embrace us. It had been months since wed seen her other than flying in the square. She smelled of lemons and cinnamon that day.We walked with Maggie and her family for a yoke of hours, talking and joking and avoiding the case that we were all thinking about until Maggie finally said, Are you two coming to my wedding?Joshua and I looked at each other as if our tongues had suddenly been struck from our mouths. I saw that Josh was having no luck findin g words, and Maggie seemed to be getting angry.Well?Uh, Maggie, its not that were not overjoyed with your right-hand(a) fortune, butShe took the opportunity to backhand me across the mouth. The jar she carried on her head didnt even waver. Amazing grace that girl had.Ouch.Good fortune? Are you mad? My husbands a toad. Im sick at the thought of him. I was just hoping you two would come to help me through the ceremony.I think my sassing is bleeding.Joshua looked at me and his eyes went wide. Uh-oh. He cocked his head, as if listening to the wind.What, uh-oh? Then I heard the commotion coming from ahead. There was a crowd gather at a small bridge a lot of shouting and waving. Since the Romans had long since passed, I assumed someone had fallen in the river.Uh-oh, Josh said again, and he began running toward the bridge.Sorry. I shrugged at Maggie, then followed Josh.At the rivers edge (no more than a creek, really) we saw a boy about our age, with wild hair and wilder eyes, stand up waist-deep in the water. He was holding something under the water and shouting at the top of his lungs.You must(prenominal) repent and atone, atone and repent Your sins have made you un uninfected. I emend you of the evil that you carry like your wallet.Thats my first cousin, joke, Joshua said.Trailing out of the water on either side of commode stood our brothers and sisters, still tied together, but the scatty link in the string of siblings was my brother Shem, who had been replaced by a lot of thrashing and bubbling muddy water in front of bum. Onlookers were delightful on the Baptist, who was having a little trouble keeping Shem under water.I think hes drowning Shem.Baptizing, Joshua said.My mother ordain be happy that Shems sins have been cleansed, but I have to think were going to be in a lot of trouble if he drowns in the process.Good point, Josh said. He stepped into the water. John Stop thatJohn looked at him and seemed a little perplexed. first cousin Joshua?Ye s. John, let him up.He has sinned, John said, as if that said it all.Ill take care of his sins.You think youre the one, dont you? Well, youre not. My birth was announced by an angel as well. It was prophesied that I would lead. Youre not the one.We should talk about this in another place. Let him up, John. Hes cleansed.John let my brother pop out of the water and I ran down and dragged him and all the other kids out of the river.Wait, the others havent been cleansed. They are filthy with sin.Joshua stepped between his brother James, who would have been the next one dunked, and the Baptist. You wont tell Mother about this, depart you?Halfway between terrified and furious, James was tearing at the knots, trying to untie the rope from around his neck. He clearly wanted vindicate on his big brother, but at the same time he didnt want to give up his brothers protection from John.If we let John baptize you long sufficient, you wont be able to tell your mother, will you, James? Me, just trying to help out.I wont tell, James said. He looked back at John, who was still staring as if hed dash out and grab someone to cleanse any second. Hes our cousin?Yes, Joshua said. The son of our mothers cousin Elizabeth.When did you meet him before?I havent.Then how did you know him.I just did.Hes a loony, said James. Youre both loonies.Yes, a family trait. Maybe when you get older you can be a loony too. You wont tell Mother.No.Good, Joshua said. You and Biff get the kids moving, will you?I nodded, shooting a glance back to John. James is right, Josh. He is a loony.I heard that, sinner John shouted. Perhaps you quest to be cleansed.John and his parents shared supper with us that evening. I was surprised that Johns parents were older than Joseph older than my grandparents even. Joshua told me that Johns birth had been a miracle, announced by the angel. Elizabeth, Johns mother, talked about it all through supper, as if it had happened yesterday instead of thirteen years ago. Whe n the old woman paused to take a breath, Joshuas mother started in about the divine announcement of her own sons birth. Occasionally my mother, feeling the need to exhibit some maternal pride that she didnt really feel, would chime in as well.You know, Biff wasnt announced by an angel, but locusts ate our garden and Alphaeus had gas for a month around the time he would have been conceived. I think it might have been a sign. That certainly didnt happen with my other boys.Ah, Mother. Did I mention that she was besought with a demon?After supper, Joshua and I built our own fire, away from the others, hoping that Maggie would seek us out, but it turned out that only John joined us.You are not the anointed one, John said to Joshua. Gabriel came to my father. Your angel didnt even have a name.We shouldnt be talking about these things, Joshua said.The angel told my father that his son would prepare the way for the Lord. Thats me.Fine, I want nothing more than for you to be the Messiah, Jo hn.Really? John asked. But your mother seems so, soJosh can raise the dead, I said.John shifted his insane gaze to me, and I scooted away from him in case he seek to hit me. He cannot, John said.Yep, Ive seen it twice.Dont, Biff, Josh said.Youre lying. Bearing false witness is a sin, John said. The Baptist started to look more panicked than angry.Im not very close at it, Joshua said.Johns eyes went wide, now with amazement instead of madness. You have done this? You have raised the dead?And healed the sick, I said.John grabbed me by the front of my tunic and pulled me close, staring into my eyes as if he was looking into my head. You arent lying, are you? He looked at Joshua. Hes not lying, is he?Joshua shook his head. I dont think so.John released me, let out a long sigh, then sat back in the dirt. The firelight caught tears sparkling in his eyes as he stared at nothing. I am so relieved. I didnt know what I would do. I dont know how to be the Messiah.Neither do I, said Joshua.We ll, I hope you really can raise the dead, John said, because this will kill my mother.We walked with John for the next three days, through Samaria, into Judea, and finally into the holy city. Fortunately, there werent some rivers or streams along the way, so we were able to keep his baptisms to a minimum. His heart was in the right place, he really did want to cleanse our people of their sins, it was just that no one would believe that God would give that responsibility to a thirteen-year-old. To keep John happy, Josh and I let him baptize our little brothers and sisters at every clay of water we passed, at least until Joshs little sister Miriam developed the sniffles and Joshua had to perform an emergency healing on her.You really can heal, John exclaimed.Well, the sniffles are easy, Joshua said. A little mucus is nothing against the power of the Lord.Would would you mind? John said, lifting up his tunic and showing his bare privates, which were covered with sores and greenish s cales.Cover, please cover I yelled. Drop the dress and step awayThats disgusting, Joshua said.Am I unclean? Ive been afraid to ask my father, and I cant go to a Pharisee, not with my father being a priest. I think its from standing in the water all of the time. Can you heal me?(I have to say here that I believe that this was the first time Joshuas little sister Miriam ever saw a mans privates. She was only six at the time, but the experience so frightened her that she never married. The last time anyone heard from her, she had cut her hair short, put on mens clothes, and moved to the classical island of Lesbos. But that was later.)Have at it, Josh, I said. Lay your hands upon the regret and heal it.Joshua shot me a dirty look, then looked back to his cousin John, with nothing but compassion in his eyes. My mother has some emollient you can put on it, he said. Lets see if that works first.Ive tried salve, John said.I was afraid you had, said Joshua.Have you tried rubbing it with olive oil? I asked. It probably wont cure you, but it might take your mind off of it.Biff, please. John is afflicted.Sorry.Joshua said, Come here, John.Oh, jeez, Joshua, I said. Youre not going to touch it, are you? Hes unclean. Let him live with the lepers.Joshua put his hands on Johns head and the Baptists eyes involute back in his head. I thought he would fall, and he did waver, but remained standing.Father, you have sent this one to prepare the way. Let him go forth with his body as clean as his spirit.Joshua released his cousin and stepped back. John opened his eyes and smiled. I am healed he yelled. I am healed.John began to raise his shirt and I caught his arm. Well take your word for it.The Baptist fell to his knees, then prostrated himself before Joshua, shoving his face against Joshs feet. You are truly the Messiah. Im sorry I ever doubted you. I shall withstand your holiness throughout the land.Uh, maybe someday, but not now, Joshua said.John looked up from where he had been grasping Joshs ankles. Not now?Were trying to keep it a secret, I said.Josh patted his cousins head. Yes, it would be best not to tell anyone about the healing, John.But why?We have to find out a couple of things before Joshua starts being the Messiah, I said.Like what? John seemed as if he would start crying again.Well, like where Joshua left his destiny and whether or not hes allowed to, uh, have an abomination with a woman.Its not an abomination if its with a woman, Josh added.Its not?Nope. Sheep, goats, pretty much any animal its an abomination. But with a woman, its something totally different.What about a woman and a goat, whats that? asked John.Thats five simoleons in Damascus, I said. Six if you want to help.Joshua punched me in the shoulder.Sorry, old joke. I grinned. Couldnt resist.John closed his eyes and rubbed his temples, as if he might vellicate some understanding out of his mind if he applied enough pressure. So you dont want anyone to know that you have the power to heal because you dont know if you can lie with a woman?Well, that and I have no idea how to go about being the Messiah, Josh said.Yeah, and that, I said.You should ask Hillel, John said. My father says hes the wisest of all of the priests.Im going to ask the Holy of Holies, Joshua said. (The Holy of Holies was the Ark of the Covenant the box containing the tablets handed down from God to Moses. No one I knew had ever seen it, as it was housed in the inner room at the Temple.)But its forbidden. Only a priest may enter the bedroom of the Ark.Yes, thats going to be a problem, I said.The city was like a huge cup that had been filled to its brim with pilgrims, then spilled into a hum pool of humanity around it. When we arrived men were already lined up as far as the Damascus gate, waiting with their lambs to get to the Temple. A greasy black smoke was on the wind, coming from the Temple, where as many as ten thousand priests would be slaughtering the lambs and burning the blo od and adipose parts on the altar. Cooking fires were burning all around the city as women prepared the lambs. A haze hung in the air, the steam and backlash of a million people and as many animals. Stale breath and sweat and the smell of piss rose in the heat of the day, meld with the bleating of lambs, the bellowing of camels, the crying of children, the ululations of women, and the low buzz of too many voices, until the air was thick with sounds and smells and God and history. Here Abraham received the word of God that his people would be the Chosen, here were the Hebrews delivered out of Egypt, here Solomon built the first Temple, here walked the prophets and the kings of the Hebrews, and here resided the Ark of the Covenant. Jerusalem. Here did I, the Christ, and John the Baptist come to find out the will of God and, if we were lucky, spot some really delicious girls. (What, you thought it was all religion and philosophy?)Our families made camp outside the northern wall of t he city, below the battlements of Antonia, the fortress Herod had built in tribute to his benefactor, Marc Antony. Two cohorts of Roman soldiers, some twelve hundred strong, watched the Temple courtyard from the fortress walls. The women feed and washed the children while Joshua and I carried lambs with our fathers to the Temple.There was something unsettling about carrying an animal to its death. It wasnt that I hadnt seen the sacrifices before, nor even eaten the Passover lamb, but this was the first time Id actually participated. I could feel the animals breathing on my neck as I carried it slung over my shoulders, and amid all the noise and the smells and the movement around the Temple, there was, for a moment, silence, just the breath and heartbeat of the lamb. I guess I fell behind the others, because my father turned and said something to me, but I couldnt hear the words.We went through the provide and into the outer courtyard of the Temple where merchants sold birds for th e sacrifice and moneychangers traded shekels for a hundred different coins from around the world. As we passed through the enormous courtyard, where thousands of men stood with lambs on their shoulders waiting to get into the inner temple, to the altar, to the slaughter, I could see no mans face. I saw only the faces of the lambs, some calm and oblivious, others with their eyes rolled back, bleating in terror, still others seeming to be stunned. I swung the lamb from my own shoulders and cradled it in my arms like a child as I backed out toward the gate. I know my father and Joseph must have come after me, but I couldnt see their faces, just conceitedness where their eyes should have been, just the eyes of the lambs they carried. I couldnt breathe, and I couldnt get out of the Temple fast enough. I didnt know where I was going, but I wasnt going inside to the altar. I turned to run, but a hand caught my shirt and pulled me back. I spun around and looked into Joshuas eyes.Its Gods w ill, he said. He laid his hands on my head and I was able to breathe again. Its all right, Biff. Gods will. He smiled.Joshua had put the lamb hed been carrying on the ground, but it didnt run away. I suppose I should have known right then.I didnt eat any of the lamb for that Passover feast. In fact, Ive never eaten lamb since that day.

Explore How Black People Are Differently Treated by the Criminal Justice System Essay

Racial prejudice is non unmatched to modern day society, it has been with us for a long time, this has been coupled with the whim that certain racial groups be slight intelligent, or backward compared to non- clear-and-blue European stock, nowhere is this more align than in the woeful evaluator system. In 1869 Francis Galton published a book called Hereditary Genius this contained a chapter called The Comparative Worth of Different Races which considered that nasty Ameri tail ends were genetically inferior to lily- albumen Ameri nookies.Galton stated that opprobriouss scored on average 15 IQ points below unobjectionables. (Coleman 1987) We can see that within the field of criminal legal expert, and with Galtons work considered that inexorable volume were bound to be interact otherwise due to a belief born(p) out of misunderstanding of the nature of culture and one-on-one character differences, the hereditary argument has never been scientifically proved or dispro ved. The 1991 census showed that 5. 5% of the creation were from an ethnic origin, with 1. 6% of these macrocosm vitriolic from an Afro-Caribbean background.It was reported that a high amount of the ethnic minorities was of younger throng than in the general macrocosm, and it can be seen that this alone could be a former for the proportionately higher level of blacks in the criminal jurist system , going on the grounds that in the indigenous race it is the younger generation, those aged 14-25 years that commit the vast majority of crime. aversion by ethnic minorities, and in particular young black males can to a fault be seen to be a brotherly situation, and may be a product of sheer logistics.Many modernistic immigrant families move into what is sensed as a high crime area, particularly inner urban center areas, where housing may be cheaper and unemployment is higher than at a discipline level. These areas may receive more police attention than richer areas and th erefore the new immigrant families come to the attention of the police more than those in more campestral areas. xenophobia may also start the police to all everywhere react when dealings with black families. A study by Goreman & Coleman (1982) looking at personality and attitudes within the British police force, showed that the average police constable was therefore racist.They asked in the study for police officers to write a short essay, some of the comments were vigorously racist, comments such as, Certain members of the coloured population that l consider met are OK entirely the majority of youths of the West Indian company are savage ignorant vicious thieving bastards , . most of them are just dirty , over 50% of trouble is caused by niggers , fouled backward people who go out never change (Coleman 1987).In the get going 10 years most public agencies, including the police force, occupy form equal opportunities policies, these apply not moreover to recruitment but also to the delegacy people are treated, and is especially needed in the criminal referee system where there are disproportionately more blacks than bloodlesss in the prison system in comparison to the size of the black population in society as a whole. It was reported in 1982 that black people made up 18% of the prison population, but only accounted for 5% of the general population.The figures are worse for Afro-Caribbean males, 1% of the population, but 11% of the prison population. (Home Office 1982). During the 1980s it became apparent that blacks were more likely to be stopped by the police. The British Crime Survey in 1988 effect that 14% of Asians, 15% of whites, but 20% of Afro-Caribbeans reported being stopped by the police in the preceding year (Skogan 1990) The British Crime Survey also reported that there was some register that crimes detected by the police and those reported by the public seemed to have a racial bias.Blacks and Asians also complained more than whites about the way they were treated once arrested by the police (Skogan 1990). On the subject of arrest it seems also that blacks are treated differently in this process. A survey by the PSI (Policy Studies Institute) in 1983 found that blacks were disproportionately arrested, they found that 5% of the population of London were black, but 17% of those arrested in London were black. Further studies by Walker (1988) & (1989) support these findings.Landau & Nathan (1983) reported that there is evidence to suggest that blacks will be cautioned less than whites, a white youngster is four multiplication more likely to receive a caution than a black juvenile. Also black juveniles are more likely to be remanded in custody than whit or Asian teenagers. Walker (1988) also showed that black juveniles are twice as likely to appear at baksheesh court than whites.A Home Office Statistical Bulletin (1986) showed that blacks in prison were more likely to have less previous convictions than whi te men in similar circumstances, the figure for whites was 62%, Afro-Caribbeans 48% and for Asians 20%.The main finding from these and many other statistics is that black people are dealt with, whether as suspects, offenders or defendants, in a highly disproportionate way, it can also be seen that they are treated more raspingly than their white counterparts at virtually every stage of the criminal justice process. It is therefore not surprising that black people have less faith in the police and criminal justice system than white British people.David Smith (1994) argues that the main group in society has a degree of power, seen to be unique and special in relation to religious, social and cultural traditions of the particular society, thus creating an unequal legal system that is non-white against ethnic minorities. This can be seen to be the stem from which racial disparities may emerge in the British legal system and criminal process, and may explain why black people are treated differently by the criminal justice system.He (Smith) further argues that the law is a national institution and part of a national identity that is born out of centuries of tradition, and therefore unless changed does not take account of relatively upstart immigration of ethnic minorities to this country. It can be argued that there are two main reasons for blacks being disproportionately represented in our criminal justice system, firstly that they commit more crime, and secondly that they are treated in a different and possibly harsher way, so as to be over represented in the criminal justice system.Research in the ground forces has shown that crime is in fact higher amongst blacks (Wilbanks 1987). This view has been criticised, for example by Reiner (1993) stating that to exclude external variables that effect such findings is almost impossible. Reiner (1989 & 1993) concluded that it is the way in which black people are treated differently from white people in our criminal ju stice system that created the disproportionate levels of minorities in the process, although he concedes that this is far from conclusive.Smith (1994) criticises Reiner for this view, believing that Reiner is contradicting himself, with dwarfish evidence, suggesting that it is treatment that cause high black representation in the criminal justice system, but stating that this may not be believed by some, and is in fact inconclusive. It is true that blacks are over represented in the criminal justice process, what is not clear is, why.Whether we like to think it or not there is chill out a great deal of racial prejudice in this country, and this alone feeds societies morals and thus its policing and criminal law, this prejudice and discrimination therefore makes it nasty for minorities to gain employment, especially in times of high unemployment and recession. This can range to feelings of rejection, lack of self-esteem, poverty, lack of self-respect and insecurity. Blacks, as me ntioned above, often live in the poorest areas of the cities and therefore come to the attention of the police far more than white youths, parents may also find it difficult to exercise control over their children in areas where social control is at its lowest.Whatever the reason for higher black crime, whether a statistical wrong, or innate criminality, for which there is little support, it is clear we will never get at the real reason that blacks are treated differently by the criminal justice system, too many people would have too much to lose by finding an answer. 1,407 words.

Fahrenheit 451 Study Questions Essay

What is the significance of Montag seeing his reflection in Clarisses eyeball? Montag sees himself in Clarisses eyes, indicating that there is a reflection of him in her. Although he does non really bang what the similarities atomic number 18 between him and her, he is aw are(predicate) that there is a connection between them. What final headspring does Clarisse petition Montag on the darkness of their first encounter?Why is the motion Copernican to the plot? On the night of their first encounter Clarisse asks Montag the question atomic number 18 you happy? Montag replies by formula yes. This question is important to the plot because it makes Montag question himself. Even though he said yes, he can incur that he is missing something in his life sentence. Although he might non know what that is he is missing, he starts to question himself and what his life really is. He and so attempts to figure out what is missing in his life and to fill the void. When Montag enters h is home, he stares at the blank wall, solely in memory sees Clarisse.What extended simile describes how he sees her? She had a very thin face like the dial if a small clock seen faintly in a evil room in the middle of a night when you waken up to see the time and see the clock put forwarding you the hour the minute, the consequence with a white silence and a glowing, all certainty and knowing what it had to tell of the night passing swiftly on toward further darknesses, further moving in like manner toward a new sun. This is the simile in which the mass describes how Montag sees Clarisse.The simile is comparing Clarisse to a clock, and how she is all-knowing with a mixed personality. At this point of realization, what happens to the smile on Montags face, and what is his answer to Clarisses question? Once Montag enters the bedroom the smile on Montags face goes away. He sees his married woman lying down on the bed motionless and he starts to feel sad. At first Montag answer ed Clarisses question by verbalise yes but later seeing his married woman lying down motionless, he begins to question his happiness.Describe Clarisses personalityClarisse is very curious and also very nice. She questions and wonders well-nigh many things. In the story, she is one and only(a) of the few mass who went outside the box and tries to do new things like playing with and tone leaves. What does Clarisse say deal talk or so? Find some examples of interpreter conversations throughout the book. Clarisse says that no one engages in an actual conversation. She says that people lonesome(prenominal) talk some televisions, cars and clothing but not a significant conversation. What is significance of the refrain repeated by the woman whose residence was burnt? What did it mean? What is its effect on Montag?The significance of the refrain repeated by the woman whose house was burn down is Play the man, Master Ridley we shall this day demoralise such a candle, by Gods gr ace, in England, as I trust shall never be put out. She is resulting to misplace her life to stand up for what she believed in, which was for the freedom to pack. Montag begins to question why books were so important to her and why she sacrificed her life. Montag starts to wonder if books had important or useful discipline in them. What does Montag think about the old woman and all the books he has destroyed? He felt guilty and depressed when he thinks about the old woman who burned with her books.He starts to understand that books are not easy to write, and that behind every book is a man who spends their lives consecrate into putting their ideas into books. He then realizes that he destroys something that person spends their whole lives reservation in a couple of minutes. Summarize Beattys explanation of how the charter for fireman arose? maitre d Beatty explains to Montag that firemen utilize to put out fires instead of position them. Since all houses and buildings ar e fireproof there is no need for firemen anymore. He then said that intellectual and talented people made another(prenominal)s uncomfortable and how books always caused appointment. Then they hired men to burn all these books since they caused conflict and those men were known as firemen. pause 2 The Sieve and the senseWhat is the meaning of the title of Part 2?The title The Sieve and the gritstone refers to an incident during Montags childhood. When Montag was young, his cousin told him that if he filled the sieve with vertebral column he would give Montag a dime. still when Montag tries to fill the sieve with gritrock, the sand just falls through the holes of the sieve no matter how austere he tries. Now history repeats itself. Montag tries to memorize parts of the Bible, specifically the bind of Ecclesiastes. However when he tries to memorize the Book of Ecclesiastes on the train, the jingle from the advertizing for Denhams Dentrifice keeps playing.Therefore Montag cann ot memorize the Book of Ecclesiastes no matter how substantial he tries because the dentrifice commercial keeps distracting him. Montag cannot memorize the words in the books because he is not used to reading since books are banned in the novel. In other words his intelligence is like a sieve and the education or words from the Bible is the sand, and no matter how hard he tries his mind can never hold the words he is trying to memorize. What is the richness of the dentrifice commercial?In the novel, the dentrifice commercial distracts Montag from focusing on memorizing the Book of Ecclesiastes. It interferes with Montags effort to think. This is the authors way of saying that how humans can easily be distracted by something as simple as a 4jingle for a product. Why does Montag go to see Faber?Montag needed to go see Faber because he hid many books in his house and he needs someone to explain what the books mean to him. He remembers he had once met a person named Faber at the par k. When they both started talking to each other Faber told Montag that he was an English professor before books were banned. Therefore Montag tried to find a way to get to and meet Faber to help him understand more about books. What does Faber tell Montag about books?Faber tells Montag that books are important and that a person should be free to purpose whether they want to read books or not. He also said that people should not be limited to obtain useful and important information that comes from books. In other words Faber tells Montag that people should have the freedom to read books. What are the three things which Faber says are missing from society? The three things which Faber says are missing from society are the forest of information, the leisure to digest it, and the honest to carry out actions based on what we learn from the interaction of the quality of information and the leisure to digest it. Describe the parlour women, their views, their conversational concerns?T he parlor women were only concerned on what new television they were going to buy. Montag sees this and turns pip the walls or television in the middle of their show. Then he asks one of the parlor women about the war. She replied by saying that her husband is being called up to help in the war. However she isnt worried she says that even if he survives she would not be sad and that she would just find another husband. Thats what she and her husband agreed on. He then asks another question, this time about children. Montag finds out that one of them would not have children and the other does but does not even care for them. Mildred, Montags wife, starts talking about politics. The parlor women tell Montag and Mildred who they voted for in the recent election. They tell them that she voted for President Noble just because he was often bump looking. Why does Montag read Dover Beach loudly to the ladies?Dover Beach is a poem about the instability of life. It speaks of acquittance of organized religion and trust. The poem is also symbolic of their society. It talks about how faith used to be full but is now retreating, to the breath of the night wind leaving only naked shingles of the human being and how this life has neither joy nor love nor light anymore. It is a great example on what human life used to be and how it has become. How do the women controvert?The women started crying after Montag read Dover Beach. Although they do not fully understand the meaning of the poem, they sense that it was a sad and discourage poem. The women are not used to this kind of emotion and do not know how to react. Therefore they start crying and left Montags house. Part 3 Burning BrightWhat is Mildreds main concern as she runs out of the house? Mildred mumbles as shes running out, Poor family, ridiculous family, oh everything gone, everything, everything gone now. Family in this context means the television walls she was so attached to. When she said that everything is gone now, she means her TV family. The TV walls were Mildreds main concern as she runs out of the house. What feelings does Montag have about the burn mark house?Montag has mixed feelings after being forced by Captain Beatty to burn his own house. In some ways he is happy. He is relieved that he burnt down all the television walls that his wife was so attached to, and he also effed the feeling of burning something again. However he was sad that he burned all the books inside the house and he was not happy that his wife started to turn on him after he burned down all the walls of the house. While Montag was in safety valve from the scene of Beattys murder, what opinion occurred to him about Beatty? After Montag kills Beatty, a thought occurred to Montag that Beatty might have wanted to die all along. When Montag used a flamethrower on Beatty, he showed no signs of defending himself as if he did not care if he died and might have possibly wanted to die all along. What is the expl anation which Montag and Faber arrive at for how so very much could have happened within one week?After Montag kills Captain Beatty he rushes to Fabers house. There he wonders to Faber on how he killed his old boss, burned his house, and lost his wife all within one week. Faber replies to Montag by saying that all of this was coming for a long time. Montag understands Faber and says that he used to think that things were wrong for a long time even though he continued with his everyday life. What are Montags impressions of the land crosswise the river? Montag was in awe of the beauty of the land across the river. He love the natural beauty of the countryside, how it seemed so much freer and more natural compared to the computerized sphere he lived in. When Montag complained about being unable to remember Mildred, what explanation did granger give him?When Montag said that he was unable to remember his past wife Mildred, Granger tells him about a story of the loss of his grandfather and how when someone dies they must leave something to be remembered by. When Granger asked Montag what Mildred left him he replied with flatus. What was Grangers philosophy on life, taught to him by his grandfather, and handed on to Montag? Grangers philosophy of life is live every spot you can as though in just ten seconds you will fall to the ground and die. He also tells Montag to leave his house and enjoy what nature has to offer, and to live life to the fullest. Describe the effects of the war as Montag imagined them.Montag imagines total destruction. He imagines Faber on his bus heading out of town, but there was no use. Where ever Fabers destination was Montag imagined that it would be meaningless. He also imagined Mildred, quietly watching her TV walls and how that the bombs would hit her. What is thepromise at the end of the novel?At the end of the novel, it talks about how a new era is about to begin. The promise is about a better world in the future, a world with huma n rights and freedom. A world in which people can read if they choose to, and how people are allowed to think of new ideas. A world of creativity and freedom.

Keeping Pets

The disadvantages of keeping prairie dogs as pets far outweigh the advantages. But the prettiness factor of these unique creatures keep the pet trade moving on with more and more people wanting prairie dogs as pets. Before you betroth on virtuoso of these animals into your guard, you should weigh all of the factors of professership so on that point will be no surprises once the prairie dog is in your home. Advantages Without a doubt, the cuteness and uniqueness factors of the prairie dog are what interest people the most.Not in truth many people devote prairie dogs so some individuals might take a crap the thrill of having the only prairie dog or dogs in the neighborhood. Their sweet faces and round bodies are adorable which attract many to wanting to own one of these animals. Their compact size excessively means they dont take up a lot of space unlike larger animals such as dogs. at any rate their constant need for companionship, care for the prairie dog is minimal. They implore a overbold cage, food and water, and toys for play and exercise. They can be litter box instruct and can be fed a high-quality rabbit pellet along with other vegetation.Disadvantages Some prairie dogs do adapt to captivity merely not very often. They can run low friendly and sociable with humans but when they dont bond with their owner, they can become stressed and bite. Be ca-ca these are social creatures, they require a lot of attention from their owner. When left alone, prairie dogs can become down in the mouth leading to behavioral problems. When prairie dogs are handled properly when young, they can socialize and become unique pets. However, many of these animals conduct been taken from their rattling(a) habitat and do not adjust to captivity.This causes many behavior issues such as opinion and biting. Because prairie dogs chew, they can escape many types of cages and when loose in the house, they can cause quite a bit of damage. Prairie dogs can also carry dise ases. An blast of monkeypox was noted in pet prairie dogs in 2003. Plague can also be transmitted to humans through prairie dogs. The chance of this occurring is low and slicks of human plague have been reported to the CDC as a way out of contact with prairie dogs. Finding a veterinarian that is knowledgeable with these animals can be difficult.If an owner is faced with a sick prairie dog, they may not have anyone who can diagnose the problem until it is too late. One of the biggest disadvantages of owning prairie dogs is the legality issue. pastime the reported cases of monkeypox in 2003, laws were specifically make to ban the capture of wild prairie dogs and restrict the travel of existing captive prairie dogs. The new laws have made it illegal to move prairie dogs from one state to another or rase within a state. Some states have made it illegal to own these animals. If you are planning on relocating, you have to receive special permit to do so.The law does allow owners to transport prairie dogs only in the case of seeking veterinary care or movement to a furnish to be euthanized. Overall, prairie dogs are not the best choices for pets. They should not be possess by someone who does not have the time to devote to their care and more importantly, they should not be purchased for children. The numbers of prairie dogs in the wild have steadily been declining in recent years. Many believe that should the promotion of prairie dogs as pets continue, their future could end up like the black-footed ferret an animal which has reached approximate extinction in the wild.

Prediction of Cross-Axis-Sensitivity of Inertial Micro-Sensor Through Modeling and Simulation

Prediction of shroud- axis- huffyness of inertial micro-sensor through modeling and guise B. P. Joshi1, A. B. Joshi2, A. S. Chaw ar2 , S. A. Gangal*2 1 Armament Research & Development Establishment (ARDE), DRDO Ministry of defense force, Dr Homi Bhabha Road, Pashan Pune-411021, India Ph. no +91-20-2588 4795, Fax no +91-20-2589 3102 E-mailemailprotected org 2 Department of Electronic Science, University of Pune, Pune-411 007, India pinch In addition to esthesia and band breadth, the bell ringer- aesthesia is an important design parameter for quickening/ inertial sensor design.In this paper prediction of cross-axis sensitivity of project casing of piezoresistive accelerometer is discussed. The effect of variation in geometrical parameters such as comprehensiveness and burdensomeness of fold & inference chain reactor (PM) on crosssensitivity are studied. Optimization of cross-sensitivity by vary geometrical parameters has been attempted. This paper deals with pretex ts of reorient type ( seam perpendicular to cogent evidence rush) and coplanar type (Flexure in prostrate with demonst dimensionn survey) social system for cross-axis sensitivity analysis. The simulation and modeling has been carried using Coventorware MEMSCAD software.Keywords Inertial sensor, Cross-sensitivity, MEMSCAD, FEM. 1 Introduction Micromachined accelerometers are widely ingestiond in many applications. gravid number of scientists all over the world are imprinting on MEMS based acceleration sensors that are mostly either capacitive or of piezoresistive type. A piezoresistive type of acceleration sensor basically consists of a proof-mass connected to a micro- sub mental synthesistilever (Flexure) all made taboo of ti. 1-4. For piezoresistive accelerometer sensitivity S is specify as relative change in resistance per unit of acceleration.fol kickoffing mathematical equation defines relation between sensor dimensions and its sensitivity 5. comparability for se nsitivity lav be written as S = K . g . L t 2 (In Pa. ) Eq. 1 Where, S is the sensitivity stress level, g is the applied acceleration, t is onerousness of curve in m, L is length of furrow in m, K is the constant of proportionality. An accelerometer is expected to absorb only adept naked as a jaybird axis. However, cannistertilever type of accelerometer is also sensitive in other direction. This undesired sensitivity is called as cross axis sensitivity.Cross axis sensitivity is the maximum sensitivity in the plane perpendicular to the sensitive direction relative to the sensitivity in the metre direction. It is calculated as the geometric sum of the 1 sensitivities in cardinal perpendicular directions in this plane 6. If Z is sensitive axis thence cross sensitivity is defined as Eq 2 Where affix (x, y, z) denotes axis in which sensitivity is measured. Effect of cross sensitivity is one of the most important design considerations. Many attempts return been made to muffl e cross sensitivity by the accelerometer designers. 7-8. Since it is a structure deflecting under work pop out of inertial force, stress is developed in the pleating due to its bending. thence it can be stated that if the breadth of bending is much greater than its thickness the cross axis sensitivity will be low. antithetic types of mechanical designs and structures have been tried by designers to reduce cross-sensitivity effect. Efficient use of four-piezoresistors in bridge structure is mostly tried structure 7. some other way to reduce cross sensitivity is multi flexure accelerometer 8.However, all these structures have a major drawback, that is, they require more processing steps as rise up as larger size on chip. In this paper, superstar cantilever type piezoresistive accelerometer is presented. The crosssensitivity is analysis is carried out by varying breadth as well as thickness of flexure and proof mass. piece of music discusses simulations carried out for skew ed and planner structure accelerometer using Coventorware software. 2 Simulations cantilever (Flexure) type of piezoresistive accelerometer is modeled and simulated using Coventorware 2003 software. Fig. shows Skewed type acceleration sensor structure, in which Flexure is perpendicular to proof mass and sensitive axis is Y-axis. The sensor is modeled with proof mass having dimension of 2000m X cdm X 200m (LxWxH) and flexure is having dimensions of 100m X 50m X 12m (LxWxH). In this structure, flexure width is in Z-axis and flexure thickness is in Y-axis. Fig. 2 shows the planar type of accelerometer of the above dimension, in which flexure is in plane with Proof mickle. In this theme, flexure width in Y-axis, thickness is in Z-axis. Z-axis is sensitive axis.Simulation is carried out using MemMech convergent thinker. The guck stress values are considered for discussion in terms of sensitivity.

Simulations are also carried out to find cross-axis sensitivity by varying thickness and width of proof mass. 3 Results and discussions 3. 1 Skewed structure (Fig 1) Simulations were carried out on skewed type of structure (of dimension mentioned in simulations above) by varying its lexure thickness. Flexure thickness is varied from 50 m to 200 m and flexure width is unplowed as 12 m. Skew structure reaction for variation in flexure thickness is shown in display panel No. 1. Here sensitive axis is Y-axis. flurry 1 Cross axis sensitivity w. r. to variation in Flex thickness for skewed structure Flexure thickness In m 50 100 cl 200 Sz Sx Sy (In MPa) (In MPa) (In MPa) 82 6. 5 340 22 1. 5 170 9. 8 0. 52 110 5. 6 0. 19 81 % Cross- predisposition 24. 19 12. 97 8. 92 6. 92 thickness to width ratio 4. 17 8. 33 12. 50 16. 67It is observed that as the flexure thickness is amplific ation while tutelage the width same, cross axis sensitivity moderates only if at the cost of sensitivity, which is not acceptable. To minimize this undesirable cross-sensitivity effect, structure is modified. In modified structure, flexure is in plane with proof mass. Fig no. 2 promote simulations are carried out with Planner structure. 3. 2 Planar Accelerometer Planner accelerometer of above-named dimensions was simulated. Varying geometrical parameters like thickness & width of proof mass as well as flexure simulations were carried out.The results are given in following paragraphs. Here sensitive axis is Z-axis. 3. 2. 1 mutations in flexure width(FW) Simulations are carried out in MEMMECH Solver by varying flexure width from 12m to 30 m while keeping flexure thickness same as 50 m. sideline table shows effect of flexure width on sensitivity as well as cross-sensitivity.

Following table shows effect of flexure thickness on sensitivity as well as cross-sensitivity.

This is because as the flexure becomes more and more stiff, cross-sensitivity decreases. 3. 2. 3 Variation in Prof mass width (PMW) Simulations are carried out in MEMMECH solver by varying proof mass width. It is varied from 400m to 1000m. Here the flexure dimensions are kept certain as 100m X 50m X 12m (LxWxH).Following table shows the effect of proof mass width on sensitivity as well as crosssensitivity.

This is due to increase in proof-mass weight. 3. 2. Var iation of Prof mass thickness (PMT) Simulations are carried out in MEMMECH solver by varying proof-mass thickness. It is varied over from 50m to 200m. Here also the flexure dimensions are kept as 100m X 50m X 12m (LxWxH). Following table shows effect of proof mass thickness on sensitivity as well as cross-sensitivity. 4 Table 5 Effect of Proof-Mass thickness variation on cross sensitivity of planar structure PM Thickness (In m) 200 150 100 50 Sensitivity Sz(In MPa) 330 250 160 82 Sx (In MPa) 28 16 6. 8 1. 6 % Cross axis Sy Sensitivity = RMS of Sx (In MPa) &Sy / Sz 25. 2 11. 42 13. 57 8. 39 5. 47 5. 45 0. 95 2. 27It can be seen from above results that cross-sensitivity decreases considerably with decrease in Proof Mass thickness but at the heavy cost of sensitivity. This due to decrease in proof mass weight. Fig No. 3 gives thickset of variation in cross-sensitivity with respect to each of the above discussed parameters.

The bending stress caused by transverse acceleration in X, Y direction is much less then stress caused by desired acceleration in Z direction. Thus for low cross-sensitivity, symmetry of width to thickness should be high. These results have good agreements with earlier report results 7-8 4) Conclusions A cross sensitivity effect is studied by varying geometrical parameter like thickness as well as width of flexure and proof mass. Following conclusions can be emaciated from all of the above simulation Skewed structure has much high cross-sensitivity as compared to planar type of structure for the same thickness to width ratio of flexure. (Compare values of in table 1 and 2 for thickness to width ratio of 4. 17). But they have similar sensitivity. When Thickness to Width ratio is increased to 8. 33 in case of skewed structure its crosssensitivity drastically reduces but is still higher than plan structure. One can safely increase sensor sensitivity by increasing proof mass weight by increasing width in planar structure. Variations in flexure thickness and Proof Mass width doesnt affect cross ensitivity. For better low cross-sensitivity, thickness to width ratio of flexure for planar type of design should be as low as possible and further sensitivity can be deepen by increasing proof mass width. 5 Acknowledgements The authors thank ARDE, Pune, Ministry of Defence for funding the research work on development of micro accelerometer at University of Pune.
