Free Capital Punishment Essays: Mandatory Death Penalty for Nitwits :: Argumentative Persuasive Topics
Mandatory Death Penalty for Nitwits à When I was in high school, my friend Mike and I earned extra money working after school and on weekends at a drugstore located at the north end of our town. Before we started working in the retail business, we both had a fairly high opinion of humanity. That is to say, we thought that the average person wouldn't try to cheat us, would be at least marginally polite, and would be smart enough to avoid walking in front of a bus. à As it turned out, we were wrong. à When we stepped behind the counter of that drugstore, we had to remove the rose-colored glasses and reexamine our cherished ideas about humanity. We found that there were many, many rude people out there and that quite a few would cheat us if they were given half a chance. We also found the average person was much less intelligent than we had thought. On Labor Day, 1995, I started a list of all the irritating and stupid things that people did while we were at work. After a while, other employees began to contribute to the list, although I compiled about 75% of the complaints. By the time I left at the end of May 1996, the list had 567 items on it, and we were referring to some of the customers by number. à In particular, I remember 337, an older lady who came in early every Saturday morning to buy a candy bar. Sadly, 337 never had the requisite fifty cents, and as she was rummaging through her purse looking for spare change (which sometimes took as long as ten minutes), impatient customers would line up behind her. Finally, she would storm off in a huff. à Incredibly, 337 would return several times over the course of the day and attempt to purchase the candy bar again. Once more would come the agonizing search through her purse, but (surprisingly enough) the change at the bottom had not bred over the course of the day, and over and over she was forced to leave in defeat and shame. à Number 337 was hardly unique, or even unusual. Every shift that I worked, I was forced to deal with people nearly as clueless as she was. Mike and I were inevitably led to the conclusion that stupidity should be painful; we thought that if stupidity were painful, people would go to great lengths to educate themselves.

Revenge is sweet!
On October the 13th she took her last breath, on November the 6th we buried her. On November the 21st I heard her call on me for the first time, and on December the 13:th it was my turn to take my last breath. Around one and a half-month ago, my little sister was killed. She was only ten years old. The police are still searching for the murderer, but they believe that it was a robber, because her mobile phone and her money had been taken away when they found her. Everybody tries to make me forget what has happened, but I can't. It was a Sunday morning when I heard her for the first time. ââ¬Å"I miss you so much, why can't you be with me?â⬠Is it you Minnie; is it my dear sister? ââ¬Å"I feel so alone in here, come and be with me.â⬠The voice was faint and husky. ââ¬Å"Minnie, can you hear me? Are you all right?â⬠ââ¬Å"I can hear you, I'm not alright, it is a terrible stench in this little coffin, and I feel so alone. Come to me, come to meâ⬠¦Ã¢â¬ ââ¬Å"Who did you talk to?â⬠ââ¬Å"Mum, it was Minnie, she told meâ⬠¦Ã¢â¬ ââ¬Å"Minnie? Stop kidding with me.â⬠ââ¬Å"I promise, it was Minnie, and she told me that she felt alone.â⬠ââ¬Å"Honey, I know you think that this is hard, it is hard for all of us, but she is dead, you did not hear her. I dream about her too, and the dreams seem to be real, but then suddenly I wake up, and realize that it's just a dream.â⬠I was just quiet. I knew that there wasn't an idea to try to make mum believing me. Maybe she was right, maybe it wasn't Minnie. But it sounded so realâ⬠¦ The dark has always made me scared. Every scary thing happens in the dark, were none can see what's happening. So when I, a couple of days after I heard Minnie for the first time, was I going to sleep, I felt a bit afraid. I don't know why, I just got an unpleasant feeling. The darkness seemed to be everywhere. Both inside and outside me. Suddenly I felt a cold wind. The window was closed, and it has never been any draught here before. I draw the duvet close to me. Then I heard her for the second time. ââ¬Å"It is cold in here. Do you think of me while your laying in your bed with you warm duvetâ⬠ââ¬Å"Oh Minnie, I'm thinking of you every second, every minute, every hour. I miss you so much.â⬠ââ¬Å"So why don't you come down to me, I'm not that deep down.â⬠ââ¬Å"Oh Minnie I wish I could. I'll make a plan, I promise, but mum will think I'm crazy if she saw me digging on the burial-ground.â⬠ââ¬Å"Come to me soon, I feel so alone in hereâ⬠¦Ã¢â¬ â⬠Iâ⬠m coming soon. Soon.â⬠The burial-ground was desolated, and the lights were not turned on yet. The sky was gray and everything looked dusky. I felt like all the tombstones stared at me, wondering why I was here. Iâ⬠ve always thought that it is nice to walk at the burial-ground at all saints day, because there is so many candles on the tombs, and I thinks that the candles shows that people care and not forget the dead humans. But now everything felt dark and forgotten. I walked to Minnie's tombstone, it was a white tombstone, and it looked quite new in opposite of the other graves. Everything was so quiet; I just heard the wind blow. I felt like I was watched on, and turned around. Behind me stood an old man, with a long white beard. He's eyes was blue, and observed me from my head to my shoes. ââ¬Å"Feeling alone?â⬠ââ¬Å"No. Just thinking.â⬠It wasn't true, I felt alone. However, I didn't want his company. ââ¬Å"Your sister down there?â⬠ââ¬Å"Yes. How did you know?â⬠ââ¬Å"I know her.â⬠ââ¬Å"How do you know her? I meant knew her.â⬠ââ¬Å"Know her. I've seen her. She is very pale, but those coffins isn't to nice.â⬠This man is crazy. ââ¬Å"Err, okay.â⬠ââ¬Å"You don't believe in me, right?â⬠I didn't know what to say. ââ¬Å"You'll see that I'm right, but trust me, do the things Minnie tells you to, or you'll end up like those.â⬠He pointed at the names at the tombstones. I closed my eyes and when I opened them again, he was gone. I thought of what he had said. Do the things Minnie tells you to? Has she told me anything? I won't dig her up, I don't even know if I've heard her, or if it is just my mind that makes it up. Well. The man was an old crazy idiot; there's no reason to listen at him. When I was lying in my bed that night, I heard her again. ââ¬Å"Why didn't you come down to me today? I heard you; you spooked to the old man at the burial-ground. Why didn't you start to dig when he was gone?â⬠ââ¬Å"Minnie, I don't even know if it is you who speaks to me.â⬠ââ¬Å"It is me, but I can prove it if you want to.â⬠ââ¬Å"How can you prove it?â⬠ââ¬Å"You'll se tomorrow. If I prove it, do you promise to go down do me then?â⬠ââ¬Å"Minnie, I don't knowâ⬠¦Ã¢â¬ ââ¬Å"Promise, or I'll leave you foreverâ⬠, she sounded a bit angry, and I was afraid that she would leave me unknowing if she were Minnie or not. ââ¬Å"Okay.â⬠ââ¬Å"Se you tomorrow then.â⬠Everything was quiet. She was gone. When I woke up next morning and thought about what Minnie had said, I felt insecure. What if she proved it? Should I go to her then? No, impossible. She can't prove it. She's dead. And if she against all odds will prove it, I won't go to her. Not yet anyway. However, she won't prove it. But she did. When I came to school I got a big shock. All over the roof there was painted; I watch every single step you take, is this evidence enough? I didn't know what to do. In school there was a lot of talk about who did it, they thought that it was one of the gangs in town. But I knew. I said to my teacher that I was sick, and that I wanted to go home. Then I walked to the park beside the burial-ground. I had been there for approximately ten minutes when she started to talk to me. ââ¬Å"What are you waiting for? Go and dig me up.â⬠Her voice sounded angry and ordering. I was just quiet. Maybe she would think that I didn't here her if I just ignored her. ââ¬Å"I know that you hear me. You're in the park. Why don't you dig me up? Are you afraid? You promised me to dig me up. If you don't dig me up, everything will be worse for you.â⬠I was afraid. How could she know where I was? And what would happen if I didn't do as she said. But I didn't say anything. She would give up, and what could she do? She was dead. ââ¬Å"I know what you're thinking, but I can do a lot. I can destroy your life, 'cause I'm manipulating it. I can promise that you'll dig me up sooner or later.â⬠Her voice was ecstatic, and it scared me. I started to walk away, but she didn't want to stop talking with me. She screamed: ââ¬Å"I'm manipulating your life, I manipulating your life, so you better dig me up soon.â⬠Her voice tormented me all day, and when I at last fell asleep I had nightmares. I dreamed that the old man at the burial-ground haunted me, and that Minnie laughed at me when I stumbled. And when I had stumbled, I couldn't stand up again. Everything turned into different red coulors, and Minnie's laugh became higher and higher. When I finally woke up, I felt like I hadn't slept at all. I went to school, and tried to not look at the roof with Minnie's message. I went in to my classroom. The first lesson was math. I hate math, so when my teacher told me to go to the front of the classroom, I felt afraid. Would she give me a hard question? ââ¬Å"Okay everybody, quiet please. We all know that somebody painted a sentence on the roof. We don't know what the culprit wants to tell us, we didn't even know who was the culprit. But now I know. I know it, 'cause the culprit by herself called to me yesterday and admit that she painted it. She said that she wanted to tell the class why she did it. So, can you tell us why?â⬠She looked at me. I didn't understand anything. ââ¬Å"Angelica, can you tell us?â⬠ââ¬Å"But it wasn't me.â⬠I felt like a fool. Damned Minnie, if it is you who have done this, you can forget every hope about that I will dig you up. ââ¬Å"Well. We all know who's the culprit now, and if you won't tell us Angelica, you can go straight away to the porter, and he'll give you the things you'll need to clean the roof.â⬠ââ¬Å"But it wasn't me.â⬠ââ¬Å"GO!â⬠I started to walk away. I was so mad at Minnie. It wasn't me, it was Minnie, so why did I have to clean the roof? However, how could she call to my teacher? And didn't my teacher recognize that it wasn't my voice that she heard? I became more and more afraid, what would she do next? She spoke to me every single minute, and her voice sounded more and more frightening. She was totally convinced that I would dig her up, and she repeated again and again that she manipulated my life. Sometimes I believed in her, because I couldn't do anything with her voice in my head. And I did a lot of things that she told me to do, I was afraid that she would do anything worse if I didn't. However, I wouldn't dig her up. The things that she got me to do was just stuff as clean her room, put her photos in a frame or say good things about her. She repeated that it would just be worse if I didn't dig her up soon. And it should, much worse. I had stopped going to school, 'cause everybody avoided me. My teacher was mean to me, and derided me when I did something wrong. At December the 11th it was time for the next thing to happen. Mum was mad at me because I didn't walk to school. But she couldn't make me change my mind. We had just had a fight, and she screamed to me that she would go to her job and do some good instead of just sit and cry. I was mad at her and at the whole world, because nobody seemed to understand anything. I walked out of the door and went to the supermarket to buy some chocolate. I had nearly accepted Minnie's voice, but today it was scarier then ever. ââ¬Å"I'm sorry to say this Angelica, but today will I hurt other people to get you dig me up.â⬠ââ¬Å"If you do that, I'll kill you.â⬠ââ¬Å"Good luck, I am already dead.â⬠ââ¬Å"I won't dig you up.â⬠ââ¬Å"Well, go home and se if you change your mind when you se what I've done.â⬠She sounded satisfied, and that made me scared. I ran home, and what I'll never forget what I saw. The first thing I saw was just that the door was red. I stared at the door a few seconds before I realized that the red thing was blood. I flung the door open, and inside I found a tail. I started to shiver. If she hadâ⬠¦ I didn't even wanted to think about it. ââ¬Å"CHARLIE!â⬠I screamed frightened. But our dog Charlie didn't come. I ran in to the living room, and there I saw Charlie. Anyway, I saw a part of him. But his head and his paws were gone. I started to scream and cry; I didn't know what to do. My thoughts was just a mess, Why do you does this to me Minnie? You loved Charlie so much, how could you ever kill him? Why do you want me to dig you up? If you are dead, why do you want me to be with you? Oh Minnie, why? I called mum. She came home as fast as she could, and we were both struck dumb. She asked me if I knew who had killed him, and I said that I didn't know. She cleaned the living room, and I walked up to my room. Minnie started to talk to me again. ââ¬Å"Do you dig me up now?â⬠ââ¬Å"No, I won't. You are terrible, I hate you.â⬠ââ¬Å"I know that you hate me, but if you don't dig me up soon, I'll have to do something worse than this. If you haven't dig me up in 24 hours, It'll be time for another harmless to die.â⬠Later that day when I was going to use the toilet I heard mum and dad talking to each other. I didn't believed what I heard. ââ¬Å"I'm worried about Angelica. It is terrible what has happened to Charlie, but in fact I'm wondering if it can be Angelica who has killed him. I know it sounds weird, but she has change a lot since Minnie died. I guess that that's normal, butâ⬠¦ I don't know; she has always loved school, and now, she hates it. Her teacher called to me and told me that she had written a form of message on the roof, and that she had admit that it was her who did it once, but said that it wasn't she later. I don't know, maybe I'm just too worried. But she has been so introspective.â⬠ââ¬Å"I guess she's just shocked about Minnie's death. But I'm worried about Charlie's death too. Maybe it is she who killed him, I'll speak to her this weekend.â⬠I was terrified. How could they even think about it? That I killed Charlie? Why can't anyone believe me? The 24 hours ran away. I didn't dig Minnie up. I'll never do it. I hate her and I won't do anything that she want's me to do. 12 hours later I had changed my mind. I can hardly think about what happened. But I'll try to tell. I had been on the burial-ground, when Minnie started to talk to me. ââ¬Å"Well, you didn't dig me up, and I've made my choice. I'm sorry that I have to do this.â⬠ââ¬Å"Do what?â⬠ââ¬Å"Go home and se for yourself.â⬠Her voice sounded honestly sad. I ran home and the first thing I smelled was a terrible stench. Then I smelled blood. I heard how daddy screamed and I ran in to the house. Inside I found dad paralyzed. And I found mum. On the floor. And I found Charlie's head. In the place where mum's head should be. ââ¬Å"Dad what has happened?â⬠ââ¬Å"I don't know. I was in the kitchen, and I heard her scream. I went in to the living-room, and I found her.â⬠ââ¬Å"Oh dad. It's all my fault. I have to do a thing. Dad, I love you. I went down to the cellar and brought a spade and ran to Minnie's grave. I have never been that angry before. ââ¬Å"Are you satisfied now Minnie?â⬠ââ¬Å"You haven't dug me up yet.â⬠Her voice was very weak. I dug as fast as I could. After a few seconds I saw the coffin. I opened it. ââ¬Å"Lay down.â⬠I did as she told me to. Nothing to lose anymore. Exactly when I lay down, the coffin's lid smashed down. I heard scratch from a spade, and I couldn't open the lid. I screamed for my life, but noon heard. I guess that I screamed for hours. At last I had no voice left. I started to investigate the coffin, and I found the head of my mother, and Charlie's paws. The last time I watched my clock it showed: Friday the 13th 13:00. The last time I heard Minnie she said: ââ¬Å"Revenge is sweet.ââ¬

Micro Manufacturing
ME 686: Micro-manufacturing Assignment 1 Study the effects of process parameters (speed, feed, depth of cut etc. ) associated with SPDT for manufacturing of micro lens let arrays. Also find out the ranges of these process parameters and values of optimal process parameters. Submitted by: Marmeek Kishor Kumar Kosambia (09010332) Submitted to : Dr. S. N. Joshi Date of Submission: 17/01/13 Introduction A microlens array is composed of a series of micro lens distributed in a regular pattern and has been usedin a wide range of photonic products.Aà micro lensà is a smallà lens, generally with aà diameterà less than aà millimetreà (mm) and often as small as 10 micrometers (à µm). The small sizes of the lenses means that a simple design can give good optical quality but sometimes unwanted effects arise due to opticalà diffractionà at the small features. A typical micro lens may be a single element with one plane surface and one spherical convex surface toà refractà the light. Because micro lenses are so small, the substrate that supports them is usually thicker than the lens and this has to be taken into account in the design.More sophisticated lenses may useà asphericalà surfaces and others may use several layers of optical material to achieve their design performance. Since surface roughness affects the performance of the lens, one needs to generate finely machined surface with minimum roughness Single Point Diamond Turning machining is a technique which removes materials from a few microns to sub-micron level to achieve ductile mode machining on hard-to-machine materials such as electro less nickel plating, silicon, quartz, glass and ceramics with no subsurface defects.Such a machining process is able to achieve mirror surface finish of less than 10 nm and form error of less than 1um easily. If properly applied to a specific range of diamond turnable materials, the process is far superior to grinding and polishing where shape control is mo re difficult and processing time is longer. The selecting and optimization of machining parameters is one of the main factors that could influence the machining accuracy. The main machining parameters are tool feed rates, spindle speed and depth of cut.The tool feed rate is normally expressed in terms of either distance travelled by the tool per unit time (mm/min) or distance travelled per unit rotation (mm/revolution). It is most common to see the distance per revolution as it is directly related to the anticipated theoretical surface finish. For a given tool feed rate, larger the tool nose radius, lower the roughness and the better the optical surface finish. The surface quality depends to great extents on the material characteristics like: grain size, micro structure or crystal boundary, crystal uniformity and annealing procedures adopted. Casual selection of combination of machining parameters may affect the surface quality, so it is required to optimize the machining parameters before final SPDT process. Machining of aspheric surface is more complicated than spherical and flat surfaces because of complicated tool path and uneven material removal. To achieve required profile tool path should be optimized. Surface roughness with respect to variable Feed rate Feed rate is most important parameter and variation of this havea great impact on the surface finish. Theoretical surface finishdepends on feed rate and tool radius.Depth of cut 2 ? m andRPM 1000 kept constant and tool feed rate is varied from 0. 5? m/rev to 5. 0 ? m/rev. the results of the experiments are asfollows. From the above experiments, it is observed that the surface finish is going down as we reduce feed. The surface roughness is 54. 8 nm at feed 0. 5 ? m where the depth of cut is 2 ? m and 1000 RPM was maintained. It is investigated that although look of the surface was good but it is not of optical quality at these parameters. We have varied the depth of cut at feed rate of 0. 5. Surface rou ghness with respect to variable depth of cutFrom the above experiments, it is observed that the surface finish is depending on the depth of cut but its behavior is different. As we increase the doc from 1? m to 2 ? m the roughness decrease from 117 nm to 54 nm and again increase the roughness on of doc. Same is again repeated on 8 ? m doc. The surface roughness is 54. 8 nm at feed 0. 5 ? m/rev where the depth of cut is 2 ? m and 1000 RPM. But it is investigated that surface is not optical at these parameters, the surface quality was dull after 10 ? m doc and there no use of increasing the doc more than 10 ? m.From the above experiments, it is observed that the surface finish is depending on the depth of cut but its behavior is different. As we increase the doc from 1? m to 2 ? m the roughness decrease from 117 nm to 54 nm and again increase the roughness on of doc. Same is again repeated on 8 ? m doc. The surface roughness is 54. 8 nm at feed 0. 5 ? m/rev where the depth of cut is 2 ? m and 1000 RPM. But it is investigated that surface is not optical at these parameters, the surface quality was dull after 10 ? m doc and there no use of increasing the doc more than 10 ? m.Surface roughness with respect to variable RPM From the last experiment we have seen that the depth of cut 2 ? m giving the better surface. During this experiment feed rate 0. 5 ? m/rev and depth of cut remained unchanged and RPM varied from 800 to 4000, to get the further better surface on the work piece. Analysis of turned work piece at different RPM is carried out. Output result is shown in above table. By experiments we have seen that polycarbonate surface turned to the surface finish of below 25 nm, which is achieved at RPM 3000. A good surface finish is achieved at 800 RPM also but it is not economical.At RPM 1500 we have observed the star pattern on surface of PC. So, RPM 3000, Feed 0. 5 ? m/rev and depth of cut 2 ? m are the optimum parameters where optical surface is achieved. An empi rical formula is developed for predicting surface roughness of diamond turned polycarbonate at different turning parameters (feed rate, depth of cut and RPM). Empirical formula is derived as follows. Optimum turning parameter are suggested where the optical surface finish in obtained. Tool feed rate : 0. 5 ? m/revolution Depth of cut : 2 ? m RPM : 3000 Tool Path CompensationAnother study shows the greatest challenge lies in selecting the optimum combination of the process parameters to get the best surface quality. The parameters chosen for optimization are as: Spindle speed (SS), Feed rate (TFR), Depth of cut (DoC). Another parameter to optimize the machining is the tool path. The tool path compensation cycle starts with the definition of desired aspheric surface by the conic equation: It is observed that by modifying the tool path, profile error ofaspheric surface is significantly reduced. The comparison between aspheric figure error, before and after tool path compensation is giv en in Table-4.Conclusions: 1) Tool feed is the dominant parameter for surface roughness followed by the spindle rotational speed. Depth of cut shows minimal effect on surface roughness compared to other parameters. 2) Depth of cut is the leading parameter for peak to valley error, followed by spindle rotational speed. Feed rate does not have considerable effect on Pt. 3) Effect of depth of cut on Pt varies with spindle speed. However, for achieving good optical surface on the polycarbonate work piece, lower depth of cut is preferred. 4) Spindle rotational speed of 2000rpm, tool feed rate of1? m/rev and depth of cut of 2? are selected for precisemachining of polycarbonate. 5) The process of the optimization of tool path helps to optimize the machining process further.

Laissezfaire1 essays
Laissezfaire1 essays Concept of the Invisible Hand in a Laissez-faire economy By preferring the support of domestic to that of foreign industry, he intends only his own security; and by directing that industry in such a manner as its produce may be of the greatest value, he intends only his own gain, and he is in this, as in many other cases, led by an invisible hand to promote an end which was no part of it. Adam Smith, Inquiry into the Nature and Causes of the Wealth of Nations 1776. What business does a government have in commerce and trade? Why would a government want to interfere between two countries benefiting from each other by trade? What right does the government have in two individuals wanting each others products or services? According to some, commerce and trade should be permitted to operate free of controls of any kind; there should be no tariffs or other barriers. This is where the term laissez-faire is introduced. Its direct translation in French, leave alone to do, is self-explanatory. A strong believer in this type of economics is Adam Smith, both a philosopher and an economist. Born on 1723 in Kirkcaldy, Fife, he studied at Oxford, and became a professor of logic at Glasgow (1751), but took up the chair of moral philosophy the following year. In 1776, he moved to London, where he published An Inquiry into the Nature and Causes of the Wealth of Nations (1776), the first major work of political economy. This examined in detail the consequences of economic freedom, such as division of labor, the function of markets, and the international implications of a laissez-faire economy. Adam Smith is most remembered today for his explanation of our market system. A majority of people saw confusion when they observed economic activity in England during the middle of the 18th century. They saw everyone doing whatever they pleased and deemed necessary. Businesses produced what ...

Pollution Prevention for Tannery Industry Essay Example
Pollution Prevention for Tannery Industry Essay Example Pollution Prevention for Tannery Industry Paper Pollution Prevention for Tannery Industry Paper Essay Topic: Water pollution The assessment identified following pollution prevention opportunities at this facility: recycling the spent chrome tanning wastes, oxidize the sulfide containing wastes, decreasing the volatile organic discharge by changing finishing materials, decreasing water use by batch washing, and using solid wastes from the waste stream as fertilizer. Chromium recycling. This step allows the collection of the spent chrome Nanning solutions, without dilution or contamination, for use in the pickle and tanning process. Since the tannery also tans splits, the spent chrome tanning solution can be used here as well. The tanning of splits results in very good fixation of chromium, so the concentration of chromium in the final effluent should meet effluent regulations. This system results in a saving of about 25 percent in the chromium chemicals used. Solvents. The suppliers of finishing products have developed water-based lacquers with significantly lower volatile solvent contents. These materials are now widely accepted as quality products, and their use is strongly advised. Process Water. In some hide wetting processes there is an opportunity to recycle the final rinses. The final rinse wastewater in this process is compatible with fluids used for the first wetting of the hides. Solid Waste. Elimination of solid leather waste discharges through the use optimizing in reconstituted leather will ease the burden on landfills. Capital Intensive Modifications. Eliminating sulfides from the effluent is very important, as they will corrode pipes, cause objectionable doors, and may cause fatal accidents. The sulfide-lime solution, and washes from this process, can be collected without contamination from other solutions. These collected wastes can be placed in a tank and the sulfides oxidized by air with a catalyst. This method is effective and can destroy the sulfide in 4-8 hours. At this point the lime waste, with high BODY and suspended solids, can be used to neutralize the acid wastes that are being continuously discharged. The acid and alkaline wastes from the tanning process will react to produce a expectoration of much of the suspended lids and BODY. This is done with a mixing tank and automatic pH control. Coagulants can also be added at this point. The neutral streams can then flow to a primary clarifier for the removal of suspended solids as sludge. The sludge can be dewatered in a sand bed to more than 50 percent solids for disposal. Although this effluent is somewhat high in BODY, over 80 percent of the pollution load have been removed. The sludge is a good soil conditioner, and if used as such, will eliminate possible high disposal costs. Secondary Treatment. In the future, a secondary treatment system can be added for BODY removal. The secondary system need only be as large as needed for the clarified wastes, and it may consist of a trickle filter, a secondary clarifier, and/ or a filter press. Environmental and Economic Benefits implementation of the suggestions will lead to a number of positive environmental and economic benefits. Chromium recycling will decrease the chromium in the discharge by 80-90 percent. It decreases chromium to less than 3 MGM/l. Costs were estimated at $20,000 (US), savings at $60,000 per year ND therefore payback period of 4 months. The reduction of volatile solvents will decrease VOCE releases to the atmosphere by 60-90 percent. Changes to water usage patterns will decrease effluent volume by 20-40 percent. Elimination of solid leather waste discharges through the use of trimmings in reconstituted leather eases the burden on landfills. This decrease leather waste by 60-80%. Costs were estimated at $1 0,000 (US). Destroy sulfides by air oxidation decreases sulfide wastes by 95- 98 percent. Costs were estimated at $30,000. (US) With primary and secondary treatment, the BODY an be reduced by 75 percent.

Early Life Henry Ford was born on July 30, 1863, one of eight and the oldest of five that survived to adulthood, of Mary Litogot Ahern and William Ford. William (1826ââ¬â1905) was an Irish immigrant, born in Clonakilty in County Cork, who fled the Irish potato famine with two borrowed pounds andà a set of carpentry tools. He settled in Detroit where a number of his uncles lived, and quickly accrued land. At three years of age, Mary Litogot Ahern (1839ââ¬â1876) and her three brothers were orphaned; Mary was adopted by a couple named Margaret and Patrick Ahern. She and William married on April 21, 1861: Marys dowry included 90 acres and after they were married, their sizable farm totaled 250 acres. By the time Henry was born, they were among the most important and wealthy families in Dearborn.à Education Henry was educated in two one-room schoolhouses, the Scottish Settlement School and the Miller School, finishing six grades. The building was eventually moved to Fords Greenfield village and opened to tourists. From his graduation in 1876 Henry worked on his fathers farm but after harvest 1878, he abruptly left, walking off without permission to Detroit where he stayed with his fathers sister Rebecca. He took a job at the streetcar manufacturer Michigan Car Company Works, but was fired after six days and had to return home. In 1879, William got Henry an apprenticeship at the James Flower and Brothers Machine shop in Detroit where he lasted 9 months, leaving for the Detroit Dry Dock Company, pioneers in iron ships and Bessemer steel. Neither job paid him enough to cover his rent, so he took a night job with a jeweler, cleaning and repairing watches.à Henry Ford returned to the farm in 1882, where he operated a small portable steam threshing machine, the Westinghouse Agricultural Engine, for a neighbor. He was very good at it, and over the summers of 1883ââ¬â1884, he was hired by the company to operate and repair engines made and sold in Michigan and northern Ohio.à Marriage and Future Plans In December of 1885, Ford met Clara Jane Bryant (1866ââ¬â1950) at a New Years Eve party and they married on April 11, 1888. Ford continued to work the farm- his father gave him an acreage- but his heart was in tinkering and and he clearly had business in mind. Over the winters of 1888-1890, Henry Ford enrolled in Goldsmith, Bryant Stratton Business University in Detroit, where he likely took penmanship, bookkeeping, mechanical drawing, and general business practices. By the early 1890s, Ford was convinced that he could construct a horseless carriage: but he didnt know enough about electricity, so in September 1891, he took a job with the Edison Illuminating Company in Detroit. After his first and only son Edsel was born on November 6, 1893, Ford was promoted to Chief Engineer. By 1896, Edison had built his first working horseless carriage, which he named a quadricyle. He sold it in order to finance work on an improved model- a delivery wagon. On April 17, 1897, Ford applied for a patent for a carburetor, and on August 5, 1899, the Detroit Automobile Company was formed. Ten days later, Ford quit the Edison Illuminating Company.à And on January 12, 1900, the Detroit Automobile Company released the delivery wagon as its first commercial automobile, designed by Henry Ford. Ford Motors Ford incorporated the Ford Motor Company in 1903, proclaiming, I will build a car for the great multitude. In October 1908, he did so, the Model T- Ford numbered his models by the letters of the alphabet, although not all of them made it to manufacture. First priced at $950, over the Model Ts nineteen years of production, its price dipped as low as $280. Nearly 15,000,000 were sold in the United States alone. The Model T heralds the beginning of the Motor Age; Fords innovation was a car evolved from luxury item for the well-to-do to an essential form of transportation for the ordinary man, that that ordinary man could repair and maintain by himself Although contrary to some reports he didnt invent the assembly line, Ford did use it to revolutionize manufacturing processes in the United States. By 1914, his Highland Park, Michigan plant used innovative production techniques to turn out a complete chassis every 93 minutes. This was a stunning improvement over the earlier production time of 728 minutes. Using a constantly-moving assembly line, subdivision of labor, and careful coordination of operations, Ford realized huge gains in productivity, and personal wealth. In 1914, Ford began paying his employees five dollars a day, nearly doubling the wages offered by other manufacturers. He cut the workday from nine to eight hours in order to convert the factory to a three-shift workday. Fords mass-production techniques would eventually allow for the manufacture of a Model T every 24 seconds. His innovations made him an international celebrity. On May 27, 1927, production ended for the Ford Model T. Legacy and Death Ford was a shrewd businessman and very much of a showman, with a fairly thin skin. In 1919 he sued the Chicago Tribune for libel for writing an editorial in which theà Tribuneà called him an anarchist and ignorant idealist.à He wrote and rewrote his biography multiple times beginning in 1922, and he sponsored the restoration of an idyllic rural town called Greenfield Village which was built in part to act as a tourist destination celebrating his life and work. Yet, Ford continued to innovate. In 1932, Henry Ford introduced his last engineering triumph: his en block, or one piece, V-8 engine; and on January 13, 1942, he patented a plastic-bodied automobile- a car 30 percent lighter than metal cars. Fords affordable Model T irrevocably altered American society. As more Americans owned cars, urbanization patterns changed. The United States saw the growth of suburbia, the creation of a national highway system, and a population entranced with the possibility of going anywhere anytime. Ford witnessed many of these changes during his lifetime, all the while personally longing for the agrarian lifestyle of his youth. The last few years, Henry Ford visibly slowed down, and on April 7, 1947, he died in his home in Dearborn. Controversy There is unfortunately ample evidence that Ford was a bigot, whose writings include several statements referring to white supremacy. According to a recent article in Quartz, even though he hired black employees and paid them the same as white ones, he was concerned that they and his other workers would be infected by the evil of jazz music, so he suggested that square dancing could be put forward as an alternative place where white people could hang out.à Sources Bryan, Ford R.
