Cytoplasm - Definition and Function

Cytoplasm - Definition and Function Cytoplasm consists of all of the contents outside of the nucleus and enclosed within the cell membrane of a cell. It is clear in color and has a gel-like appearance. Cytoplasm is composed mainly of water but also contains enzymes, salts, organelles, and various organic molecules. Cytoplasm Functions The cytoplasm functions to support and suspend organelles and cellular molecules. Many cellular processes also occur in the cytoplasm. Some of these processes include protein synthesis, the first stage of cellular respiration (known as glycolysis), mitosis, and meiosis. In addition, the cytoplasm helps to move materials, such as hormones, around the cell and also dissolves cellular waste. Divisions The cytoplasm can be divided into two primary parts: the endoplasm (endo-,-plasm) and ectoplasm (ecto-,-plasm). The endoplasm is the central area of the cytoplasm that contains the organelles. The ectoplasm is the more gel-like peripheral portion of the cytoplasm of a cell. Components Prokaryotic cells, such as bacteria and archaeans, do not have a membrane-bound nucleus. In these cells, the cytoplasm consists of all of the contents of the cell inside the plasma membrane. In eukaryotic cells, such as plant and animal cells, the cytoplasm consists of three main components. They are the cytosol, organelles, and various particles and granules called cytoplasmic inclusions. Cytosol: The cytosol is the semis of organelles include mitochondria, ribosomes, nucleus, lysosomes, chloroplasts, endoplasmic reticulum, and Golgi apparatus. Also located within the cytoplasm is the cytoskeleton, a network of fibers that help the cell maintain its shape and provide support for organelles.Cytoplasmic Inclusions: Cytoplasmic inclusions are particles that are temporarily suspended in the cytoplasm. Inclusions consist of macromolecules and granules. Three types of inclusions found in the cytoplasm are secretory inclusions, nutritive inclusions, and pigment granules. Examples of secretory inclusions are proteins, enzymes, and acids. Glycogen (glucose storage molecule) and lipids are examples of nutritive inclusions. Melanin found in skin cells is an example of a pigment granule inclusion. Cytoplasmic Streaming Cytoplasmic streaming, or cyclosis, is a process by which substances are circulated within a cell. Cytoplasmic streaming occurs in a number of cell types including plant cells, amoeba, protozoa, and fungi. Cytoplasmic movement may be influenced by several factors including the presence of certain chemicals, hormones, or changes in light or temperature. Plants employ cyclosis to shuttle chloroplasts to areas receiving the most available sunlight. Chloroplasts are the plant organelles responsible for photosynthesis and require light for the process. In protists, such as amoeba and slime molds, cytoplasmic streaming is used for locomotion. Temporary extensions of the cytoplasm known as pseudopodia are generated that are valuable for movement and capturing food. Cytoplasmic streaming is also required for cell division as the cytoplasm must be distributed among daughter cells formed in mitosis and meiosis. Cell Membrane The cell membrane or plasma membrane is the structure that keeps cytoplasm from spilling out of a cell. This membrane is composed of phospholipids, which form a lipid bilayer that separates the contents of a cell from the extracellular fluid. The lipid bilayer is semi-permeable, meaning that only certain molecules are able to diffuse across the membrane to enter or exit the cell. Extracellular fluid, proteins, lipids, and other molecules may be added to a cells cytoplasm by endocytosis. In this process, molecules and extracellular fluid are internalized as the membrane turns inward forming a vesicle. The vesicle encloses the fluid and molecules and buds off from the cell membrane forming an endosome. The endosome moves within the cell to deliver its contents to their appropriate destinations. Substances are removed from the cytoplasm by exocytosis. In this process, vesicles budding from Golgi bodies fuse with the cell membrane expelling their contents from the cell. The cell membrane also provides structural support for a cell by serving as a stable platform for the attachment of the cytoskeleton and cell wall (in plants).

Leave out the Latin - Emphasis

Leave out the Latin Leave out the Latin One of our members of staff recently phoned his GP practice and asked to see a specific doctor. Sorry, he only comes in pro re nata, the receptionist told him. It wasnt until hed put the phone down and looked up the phrase that he knew for sure what she had meant, writes Cathy Relf. It would be considered crass and more than a little odd for a native English speaker speaking to another native English speaker to switch to another language mid-sentence. So why do some people think its acceptable to do so with Latin? To be effective, writing needs to be clear and accessible. It shouldnt confuse the reader or require them to reach for a dictionary. In fact, when someone has to look away for long enough to look up a word, they may never return. Only a minority of native English speakers have any formal knowledge of Latin. In the UK in 2011, just 9,650 pupils out of a total of 5.15 million took a Latin GCSE. Thats less than two per cent. Admittedly, that proportion was slightly higher when your average businessperson was at school, but the fact remains that the moment you slip in a line of Latin, or even over-pepper a sentence with post, ad hoc and per se, whether its apropos (appropriate) or not, you risk alienating the majority of your readership. There are some professions medicine and law, for example where Latin is a crucial part of the language (although lawyer Wayne Schiess makes a good case against using unnecessary Latin in legal writing). But outside of those professions, there are few cases where using an expression that your readers may not understand would be better than writing it in plain English. This isnt to say theres anything wrong with studying or taking an interest in Latin after all, much of our language is based on it. And its fine to use commonly understood abbreviations such as eg, ie, etc, if theyre genuinely more appropriate than for example, that is, and and so on. Just make sure you use them correctly. Latin on the loose Weve rounded up five examples of Latin obstructing meaning, below. If youre not familiar with the Latin terms, hover over them for a rough translation, or click to see the full definition. Heres Kathy Gyngell blogging for the Daily Mail: This is what the Bishops amendment to exclude child benefit from Iain Duncan Smiths benefit cap plan, inter alia, endorses the continuation of entitlement. A paper from the Social Development Agency: This Vademecum is intended as a handy reference guide to using budget heading 04.03.03.03. on information, consultation and participation of representatives within undertakings. A Wired.com article on the rules of cooking: While there are certainly still subjective and somewhat impenetrable qualities to ones cuisine de gustibus non est disputandum there is an increasing rigor in the kitchen. An article on robo-cars: And given the Supreme Courts recent ruling on police use of GPS, even when tracking criminals, the idea that more technology in the car leads ipso facto to more government control is questionable. And, making a case for the teaching of Latin in schools, Boris Johnson writing in the Telegraph: Suppose you are captured by cannibals in the Mato Grosso, and you find a scrap of Portuguese newspaper in your hut revealing that there is about to be an eclipse; and suppose that by successfully prophesying this event you convince your captors that you are a god and secure your release I reckon you would be thankful for your Latin, eh? And even if you reject any such practical advantages (and, experto crede, they are huge), I dont care, because they are not the point. How many of them could you follow, without checking the definitions? With the possible exception of Boris Johnson, whose Latin is at least relevant to the subject in hand, these are all quite bizarre language choices. In the first case, among other things would have been a much better and clearer expression than inter alia. In the second, the use of Vademecum (or vade mecum, as it is more commonly spelt) alongside handy reference guide is tautologous. It essentially says this handy reference guide is intended as a handy reference guide. In the third, what purpose could there be for writing in Latin, other than for the writer to show that he can? And in the fourth, the ipso facto is unnecessary if any clarification is needed, automatically or directly would do fine. The case against While studying Latin is admirable, using it in everyday language isnt. Not only does it sound pompous and offputting, it obstructs communication. Even Boris doesnt make an argument for actually using it, merely for knowing it in case of encounters with cannibals who cant read newspapers. When writing, always keep your readers at the front of your mind. What do they need to know, and how can you best communicate it? If the answer to the second question is in Latin, then by all means go ahead but those occasions are, we suspect, rare. Wed love to hear your thoughts. Have you spotted some Latin on the loose? Can you defend any of the above examples? Do you have a particular phrase that youre fond of dropping into writing? Leave us a comment below.

Political Science- Indigenous Autonomy and State Development Tensions Research Paper

Political Science- Indigenous Autonomy and State Development Tensions - Research Paper Example Examining the different effects which this has as well as how it can be altered to begin to incorporate different concepts within both areas then provides alternatives to ensure that there is more unity between the two populations while creating a stronger balance with both the indigenous and state populations. The difficulties which are occurring in Latin America between the state and indigenous populations are based specifically on the agenda of both and the identity which both holds. The indigenous populations have specific issues with the development of the country into modern terms. This is taking away the identity, cultural affiliations and basic rights of the indigenous population and the beliefs which they hold. At the same time, the state is being pressured to continue to develop and open the country for different activities that can stimulate the economy, communities and other objectives that are within politics. The pressures which are arising have come from the belief that the indigenous populations are becoming oppressed with the actions of the state while losing both identity and culture in Latin America. This is being developed specifically by the political movements, social conflicts and the pressures to establish new components within the country (Sieder, 29). The problem which is a part of the indigenous and state cultures of Latin America needs to find new solutions for both development and preservation of the cultures which are associated in given regions. The question of whether corporate social responsibility is one which can be used to alter the tensions in the region then become associated with the culture and affiliations with Latin America. The ideology of corporate social responsibility is one which requires businesses recognizing the indigenous cultures and needs within the general population. The actions which take place are then developed to help those which are in

African Americans as the Vulnerable Population Term Paper

African Americans as the Vulnerable Population - Term Paper Example Within the United States, racial segregation often implied the physical separation together with provision of separate services or facilities (mostly during the era of Jim Crow), although it could also refer to other distinct racial discrimination manifestations. For at least two hundred years before the beginning of the civil war, slavery is said to have existed within America. However, after this war, things moved from bad to worse for the black community. The southern part of America, especially, felt that they actually needed to move with speed and come up with legislation that would restrict the movement and association of blacks with other majority races. The former confederates, southern legislatures opted to pass laws popularly regarded as black codes, which immensely limited the blacks’ rights and subsequently segregated them from the white community. There had been no need for separating blacks and whites since approximately 95% of the blacks had been salves. However, they were still separated at taverns, theatres, schools and other social places. The blacks, therefore, witnessed a series of segregation tendencies from their white counterparts and with time, they got to adopt the situation. It is with this regard that congress swiftly moved to respond to this legislation in 1866 and managed to seize the responsibility of remaking the south. The Republican group demanded that the remaking of the south be marked by the viability of freed blacks in the society (John, 1997). By 1868, most of the laws, which happened to discriminate against the blacks, were effectively repealed.

A Quality Leader Essay Example for Free

A Quality Leader Essay Dr. Karoru Ishikawa is one of the world’s idolized leaders in quality control. His famous quote† Through total quality control with the participation of all employees, including the president, any company can create better products (or service) at a lower cost, increase sales, improve profit and make the company into a better organization ( Dr. Kaoru Ishikawa) . Ishikawa joined the Union of Japanese Scientist and Engineers, a quality research group back in 1949. The Japanese was concerned about their industry sector since it was known that American manufacturing was producing cheap toys and defective cameras. This group took on the responsibility of Japan’s quality-improvement; that was when Ishikawa took the initiative to build on Feigenbaum’s concept of total quality and promoted greater involvement by all employees, from the top management to the front-line staff, by reducing reliance on quality professionals and quality departments. He advocated collecting and analyzing factual data using simple visual tools, statistical techniques, and teamwork as the foundations for implementing total quality. Like others, Ishikawa believed that quality begins with the customer and therefore, understanding customers’ needs is the basis for improvement, and that complaints should be actively sought. (Evans, 2010 pg 110) Background Kaoru Ishikawa was born in 1915 in Tokyo. He graduated from Tokyo University in 1939 with a degree in Applied Chemistry. In his brief tour in the military as a Naval Technical Officer In charge of 600 workers to construct a factory he quoted â€Å"This experience he says was invaluable to Quality Control activities later on. †, (Dr. Kaoru Ishikawa) He worked for Nissan Liquid Fuel Company from 1941-1947 before he was appointed associate Professor of the University of Tokyo. In 1949 He joined the Union of Japanese Scientist and Engineers because he wanted to change the way people thought about work and help management improve the quality of their product. In 1970 Dr. Ishikawa started conducting quality control training seminars. Around 1978 Dr. Ishikawa became the President of Musashi Institute of Technology. Upon Ishikawa’s 1989 death, Dr. Juran delivered this message: â€Å"There is so much to be learned by studying how Dr. Ishikawa managed to accomplish so much during a single lifetime. In my observation, he did so by applying his natural gifts in an exemplary way. He was dedicated to serving society rather than serving himself. His manner was modest, and this elicited the cooperation of others. † (Dr. Joseph M. Juran) Primary work and significant accomplishments Dr. Kaoru Ishikawa accomplishments have include helping thousands of companies, like IBM, Bridgestone, and Komatsu, to turn out higher quality products at considerable lower costs. His book,†What is Total Quality Control? The Japanese Way†, Prentice Hall, Inc. was a best seller in business books. He has been awarded the Deming Prize and the Nihon Keizai Press Prize, the Industrial Standardization Prize for his writings on Quality Control, and the Grant Award in 1971 from the American Society for Quality Control for his education programmer on Quality Control. Process Improvement Japan, 2012). His creation of the fishbone diagram, the user can see all possible root causes of process imperfections. There are many other accomplishments that Dr. Ishikawa has made, which you can find in books and online. These were deserving awards due to his unselfish work ethics and have truly made him a quality genius. Conclusion Through total quality control a company of any type can stay in business, make products at lower cost, and endure great productivity from its workers. Dr Ishikawa wanted to change the way workers and management do business. Quality should start with the customer and it can be done using his writings, fishbone diagram, and other tools like control charts, run charts, histogram, scatter diagram, Pareto charts, and flowcharts. His knowledge was needed in a time when people wanted a product that will last and was supported by the company who makes it. His many accomplishments and strong work ethics influenced many companies to change and many of those companies are still in business today. Dr. Ishikawa is truly a leader in quality control.

Investigation to Find the Relative Energy Release of Five Alcohols: Eth

Investigation to Find the Relative Energy Release of Five Alcohols: Ethanol, Methanol, Propanol, Butanol and Propanol Aim: In this experiment I will investigate to see which alcohol releases the most energy during combustion; Methanol, Ethanol, Propanol, Butanol or Pentanol. Hypothesis: I think that the alcohols with the longest carbon chains will release the most energy. This is because when a bond is broken energy is released. This means that the alcohols with longer chains and therefore more bonds will release more energy. This will mean they will heat the water quickest. This should mean that Pentanol will heat the water by the largest mount in 5 minutes. However, because of the longer hydrocarbon chains and therefore more bonds, Pentanol will also be the hardest to ignite, least volatile and least viscous. Despite the larger requirement for input of energy, the amount created by the breaking of bonds should increase by more which will mean that Pentanol will still release more energy than Methanol, Ethanol, Propanol and Butanol. To test this I have performed several calculations. By using figures for the amount of KJ/mol that the breaking of various bonds (O-O, C-H, O-H, C-C, C-O) release I have calculated the amount of energy that is needed to combust each of the alcohols. GRAPH The calculations that I have performed have proved my theory to be correct. Pentanol is quite clearly the alcohol that should release more energy, more than five times as much as Methanol, but my experiment will show whether this extra energy can be put to good use, or if too much is wasted for it to be useful. The calculations show that Pentanol will release more energy. Even though the combustion product... ...could have effected the amount of alcohol that was getting to the tip of the wick to be burnt. Also, the wicks were made of many different materials. Although the wick itself does not burn the different materials may have soaked up more of the alcohols allowing them to burn easier. However, I do think that the method that we developed was the best way that we could have done the experiment. The overall method was very successful and allowed us to complete the experiment efficiently. However, I would quite like to repeat the experiment. I would definitely try to change the method so that the experiment is in a more controlled environment. This would prevent several factors, such as the wind, from effecting or results as they did in this experiment. Overall the experiment was relatively successful and provided us with a fairly useless, but interesting, set of results.

Breadcrafter’s breads Essay

This business plan is a tightly constructed, succinct consideration of all factors relevant to launching this bakery. From rent charges to competition and seasonal changes to costs per loaf, this plan hasn’t left anything out†¦all without being overly verbose. This exemplary plan is very focused and complete, which will help the business stay on course. Breadcrafter’s breads will stand out from the competition due to their uniqueness and outstanding quality. Most of the breads are European in style, including Sourdough, Miche (a traditional French whole wheat bread), and Sourdough Rye. These breads are made by the sourdough method which uses no added yeast. This method imparts a rich flavor, which can be tangy or mild, as well as a toothsome inner crumb and a crackly crust. By using this method, a skilled baker can create truly delicious breads without added fats or sugars, making many of Breadcrafter’s products 100% fat free. Sourdough breads also have an extended shelf life, remaining fresh for days without the use of preservatives. Breadcrafter will also offer specialty breads, which will be made in the sourdough way with the addition of such luxurious ingredients as Parmagian cheese with fresh ground pepper and dried Michigan cherries with roasted pecans. Spent Grain Bread, made with barley leftover from beer brewing, is another unique product that Breadcrafter will offer. Two varieties of French style baguettes will be offered fresh daily, a high demand product that is available nowhere else in the area. Breadcrafter will also produce White and Wheat Sandwich Breads with soft crust and a tender crumb for traditional American Style sandwiches. As the needs of the customer change, so will the lineup of Breadcrafter’s products. The bakery equipment is chosen with versatility in mind. After establishing the business, Breadcrafter will research the possibility of producing sandwiches to increase revenues. This investment would require approximately $1500.00 for the purchase of equipment and ingredients. The company will also pursue wholesale contracts. Toothsome Foods Company has indicated interest in a contract to produce two Christmas products on a per loaf basis, Cherry Chocolate Fruitcake and Midwest Christmas Stollen. These products can help generate revenues in the slower Autumn months. The proprietor will also consider producing some of Toothsome Foods’ current lineup of Handmade Breads on a wholesale basis.

Second Foundation 14. Anxiety

Poli placed the breakfast on the table, keeping one eye on the table news-recorder which quietly disgorged the bulletins of the day. It could be done easily enough without loss of efficiency, this one-eye-absent business. Since all items of food were sterilely packed in containers which served as discardable cooking units, her duties vis-a-vis breakfast consisted of nothing more than choosing the menu, placing the items on the table, and removing the residue thereafter. She clacked her tongue at what she saw and moaned softly in retrospect. â€Å"Oh, people are so wicked,† she said, and Darell merely hemmed in reply. Her voice took on the high-pitched rasp which she automatically assumed when about to bewail the evil of the world. â€Å"Now why do these terrible Kalganese† – she accented the second syIlable and gave it a long â€Å"a† – â€Å"do like that? You'd think they'd give a body peace. But no, it's just trouble, trouble, all the time. â€Å"Now look at that headline: ‘Mobs Riot Before Foundation Consulate.' Oh, would I like to give them a piece of my mind, if I could. That's the trouble with people; they just don't remember. They just don't remember, Dr. Darell – got no memory at all. Look at the last war after the Mule died – of course I was just a little girl then – and oh, the fuss and trouble. My own uncle was killed, him being just in his twenties and only two years married, with a baby girl. I remember him even yet – blond hair he had, and a dimple in his chin. I have a trimensional cube of him somewheres- â€Å"And now his baby girl has a son of her own in the navy and most like if anything happens- â€Å"And we had the bombardment patrols, and all the old men taking turns in the stratospheric defense – I could imagine what they would have been able to do if the Kalganese had come that far. My mother used to tell us children about the food rationing and the prices and taxes. A body could hardly make ends meet- â€Å"You'd think if they had sense people would just never want to start it again; just have nothing to do with it. And I suppose it's not people that do it, either; I suppose even Kalganese would rather sit at home with their families and not go fooling around in ships and getting killed. It's that awful man, Stettin. It's a wonder people like that are let live. He kills the old man – what's his name – Thallos, and now he's just spoiling to be boss of everything. â€Å"And why he wants to fight us, I don't know. He's bound to lose – like they always do. Maybe it's all in the Plan, but sometimes I'm sure it must be a wicked plan to have so much fighting and killing in it, though to be sure I haven't a word to say about Hari Seldon, who I'm sure knows much more about that than I do and perhaps I'm a fool to question him. And the other Foundation is as much to blame. They could stop Kalgan now and make everything fine. They'll do it anyway in the end, and you'd think they'd do it before there's any damage done.† Dr. Darell looked up. â€Å"Did you say something, Poli?† Poli's eyes opened wide, then narrowed angrily. â€Å"Nothing, doctor, nothing at all. I haven't got a word to say. A body could as soon choke to death as say a word in this house. It's jump here, and jump there, but just try to say a word-† and she went off simmering. Her leaving made as little impression on Darell as did her speaking. Kalgan! Nonsense! A merely physical enemy! Those had always been beaten! Yet he could not divorce himself of the current foolish crisis. Seven days earlier, the mayor had asked him to be Administrator of Research and Development. He had promised an answer today. Well- He stirred uneasily. Why, himself! Yet could he refuse? It would seem strange, and he dared not seem strange. After all, what did he care about Kalgan. To him there was only one enemy. Always had been. While his wife had lived, he was only too glad to shirk the task; to hide. Those long, quiet days on Trantor, with the ruins of the past about them! The silence of a wrecked world and the forgetfulness of it all! But she had died. Less than five years, all told, it had been; and after that he knew that he could live only by fighting that vague and fearful enemy that deprived him of the dignity of manhood by controlling his destiny; that made life a miserable struggle against a foreordained end; that made all the universe a hateful and deadly chess game. Call it sublimation; he, himself did can it that – but the fight gave meaning to his life. First to the University of Santanni, where he had joined Dr. Kleise. It had been five years well-spent. And yet Kleise was merely a gatherer of data. He could not succeed in the real task – and when Darell had felt that as certainty, he knew it was time to leave. Kleise may have worked in secret, yet he had to have men working for him and with him. He had subjects whose brains he probed. He had a University that backed him. All these were weaknesses. Kleise could not understand that; and he, Darell, could not explain that. They parted enemies. It was well; they had to. He had to leave in surrender – in case someone watched. Where Kleise worked with charts; Darell worked with mathematical concepts in the recesses of his mind. Kleise worked with many; Darell with none. Kleise in a University; Darell in the quiet of a suburban house. And he was almost there. A Second Foundationer is not human as far as his cerebrum is concerned. The cleverest physiologist, the most subtle neurochemist might detect nothing – yet the difference must be there. And since the difference was one of the mind, it was there that it must be detectable. Given a man like the Mule – and there was no doubt that the Second Foundationers had the Mule's powers, whether inborn or acquired – with the power of detecting and controlling human emotions, deduce from that the electronic circuit required, and deduce from that the last details of the encephalograph on which it could not help but be betrayed. And now Kleise had returned into his life, in the person of his ardent young pupil, Anthor. Folly! Folly! With his graphs and charts of people who had been tampered with. He had learned to detect that years ago, but of what use was it. He wanted the arm; not the tool. Yet he had to agree to join Anthor, since it was the quieter course. Just as now he would become Administrator of Research and Development. It was the quieter course! And so he remained a conspiracy within a conspiracy. The thought of Arcadia teased him for a moment, and he shuddered away from it. Left to himself, it would never have happened. Left to himself, no one would ever have been endangered but himself. Left to himself- He felt the anger rising-against the dead Kleise, the living Anthor, all the well-meaning fools- Well, she could take care of herself. She was a very mature little girl. She could take care of herself! It was a whisper in his mind- Yet could she? *** At the moment, that Dr. Darell told himself mournfully that she could, she was sitting in the coldly austere anteroom of the Executive Offices of the First Citizen of the Galaxy. For half an hour she had been sitting there, her eyes sliding slowly about the walls. There had been two armed guards at the door when she had entered with Homir Munn. They hadn't been there the other times. She was alone, now, yet she sensed the unfriendliness of the very furnishings of the room. And for the first time. Now, why should that be? Homir was with Lord Stettin. Well, was that wrong? It made her furious. In similar situations in the book-films and the videos, the hero foresaw the conclusion, was prepared for it when it came, and she – she just sat there. Anything could happen. Anything! And she just sat there. Well, back again. Think it back. Maybe something would come. For two weeks, Homir had nearly lived inside the Mule's palace. He had taken her once, with Stettin's permission. It was large and gloomily massive, shrinking from the touch of life to lie sleeping within its ringing memories, answering the footsteps with a hollow boom or a savage clatter. She hadn't liked it. Better the great, gay highways of the capital city; the theaters and spectacles of a world essentially poorer than the Foundation, yet spending more of its wealth on display. Homir would return in the evening, awed- â€Å"It's a dream-world for me,† he would whisper. â€Å"If I could only chip the palace down stone by stone, layer by layer of the aluminum sponge. If I could carry it back to Terminus- What a museum it would make.† He seemed to have lost that early reluctance. He was eager, instead; glowing. Arcadia knew that by the one sure sign; he practically never stuttered throughout that period. One time, he said, â€Å"There are abstracts of the records of General Pritcher-â€Å" â€Å"I know him. He was the Foundation renegade, who combed the Galaxy for the Second Foundation, wasn't he?† â€Å"Not exactly a renegade, Arkady. The Mule had Converted him.† â€Å"Oh, it's the same thing.† â€Å"Galaxy, that combing you speak of was a hopeless task. The original records of the Seldon Convention that established both Foundations five hundred years ago, make only one reference to the Second Foundation. They say if's located ‘at the other end of the Galaxy at Star's End.' That's all the Mule and Pritcher had to go on. They had no method of recognizing the Second Foundation even if they found it. What madness! â€Å"They have records† – he was speaking to himself, but Arcadia listened eagerly – â€Å"which must cover nearly a thousand worlds, yet the number of worlds available for study must have been closer to a million. And we are no better off-â€Å" Arcadia broke in anxiously, â€Å"Shhh-h† in a tight hiss. Homir froze, and slowly recovered. â€Å"Let's not talk,† he mumbled. And now Homir was with Lord Stettin and Arcadia waited outside alone and felt the blood squeezing out of her heart for no reason at all. That was more frightening than anything else. That there seemed no reason. On the other side of the door, Homir, too, was living in a sea of gelatin. He was fighting, with furious intensity, to keep from stuttering and, of course, could scarcely speak two consecutive words clearly as a result. Lord Stettin was in full uniform, six-feet-six, large-jawed, and hard-mouthed. His balled, arrogant fists kept a powerful time to his sentences. â€Å"Well, you have had two weeks, and you come to me with tales of nothing. Come, sir, tell me the worst. Is my Navy to be cut to ribbons? Am I to fight the ghosts of the Second Foundation as well as the men of the First?† â€Å"I†¦ I repeat, my lord, I am no p†¦ pre†¦ predictor. I†¦ I am at a complete†¦ loss.† â€Å"Or do you wish to go back to warn your countrymen? To deep Space with your play-acting. I want the truth or I'll have it out of you along with half your guts.† â€Å"I'm t†¦ telling only the truth, and I'll have you re†¦ remember, my l†¦ lord, that I am a citizen of the Foundation. Y†¦ you cannot touch me without harvesting m†¦ m†¦ more than you count on.† The Lord of Kalgan laughed uproariously. â€Å"A threat to frighten children. A horror with which to beat back an idiot. Come, Mr. Munn, I have been patient with you. I have listened to you for twenty minutes while you detailed wearisome nonsense to me which must have cost you sleepless nights to compose. It was wasted effort. I know you are here not merely to rake through the Mule's dead ashes and to warm over the cinders you find. ***You came here for more than you have admitted. Is that not true?† Homir Munn could no more have quenched the burning horror that grew in his eyes than, at that moment, he could have breathed. Lord Stettin saw that, and clapped the Foundation man upon his shoulder so that he and the chair he sat on reeled under the impact. â€Å"Good. Now let us be frank. You are investigating the Seldon Plan. You know that it no longer holds. You know, perhaps, that I am the inevitable winner now; I and my heirs. Well, man, what matters it who established the Second Empire, so long as it is established. History plays no favorites, eh? Are you afraid to tell me? You see that I know your mission.† Munn said thickly, â€Å"What is it y†¦ you w†¦ want?† â€Å"Your presence. I would not wish the Plan spoiled through overconfidence. You understand more of these things than I do; you can detect small flaws that I might miss. Come, you will be rewarded in the end; you will have your fair glut of the loot. What can you expect at the Foundation? To turn the tide of a perhaps inevitable defeat? To lengthen the war? Or is it merely a patriotic desire to die for your country?† â€Å"I†¦ I-† He finally spluttered into silence. Not a word would come. â€Å"You will stay,† said the Lord of Kalgan, confidently. â€Å"You have no choice. Wait† – an almost forgotten afterthought – â€Å"I have information to the effect that your niece is of the family of Bayta Darell.† Homir uttered a startled: â€Å"Yes.† He could not trust himself at this point to be capable of weaving anything but cold truth. â€Å"It is a family of note on the Foundation?† Homir nodded, â€Å"To whom they would certainly b†¦ brook no harm.† â€Å"Harm! Don't be a fool, man; I am meditating the reverse. How old is she?† â€Å"Fourteen.† â€Å"So! Well, not even the Second Foundation, or Hari Seldon, himself, could stop time from passing or girls from becoming women.† With that, he turned on his heel and strode to a draped door which he threw open violently. He thundered, â€Å"What in Space have you dragged your shivering carcass here for?† The Lady Callia blinked at him, and said in a small voice, â€Å"I didn't know anyone was with you.† â€Å"Well, there is. I'll speak to you later of this, but now I want to see your back, and quickly.† Her footsteps were a fading scurry in the corridor. Stettin returned, â€Å"She is a remnant of an interlude that has lasted too long. It will end soon. Fourteen, you say?† Homir stared at him with a brand-new horror! Arcadia started at the noiseless opening of a door – jumping at the jangling sliver of movement it made in the comer of her eye. The finger that crooked frantically at her met no response for long moments, and then, as if in response to the cautions enforced by the very sight of that white, trembling figure, she tiptoed her way across the floor. Their footsteps were a taut whisper in the corridor. It was the Lady Callia, of course, who held her hand so tightly that it hurt, and for some reason, she did not mind following her. Of the Lady Callia, at least, she was not afraid. Now, why was that? They were in a boudoir now, all pink fluff and spun sugar. Lady Callia stood with her back against the door. She said, â€Å"This was our private way to me†¦ to my room, you know, from his office. His, you know.† And she pointed with a thumb, as though even the thought of him were grinding her soul to death with fear. â€Å"It's so lucky†¦ it's so lucky-† Her pupils had blackened out the blue with their size. â€Å"Can you tell me-† began Arcadia timidly. And Callia was in frantic motion. â€Å"No, child, no. There is no time. Take off your clothes. Please. Please. I'll get you more, and they won't recognize you.† She was in the closet, throwing useless bits of flummery in reckless heaps upon the ground, looking madly for something a girl could wear without becoming a living invitation to dalliance. â€Å"Here, this will do. It will have to. Do you have money? Here, take it all – and this.† She was stripping her ears and fingers. â€Å"Just go home – go home to your Foundation.† â€Å"But Homir†¦ my uncle.† She protested vainly through the muffling folds of the sweet-smelling and luxurious spun-metal being forced over her head. â€Å"He won't leave. Poochie will hold him forever, but you mustn't stay. Oh, dear, don't you understand?† â€Å"No.† Arcadia forced a standstill, â€Å"I don't understand.† Lady Callia squeezed her hands tightly together. â€Å"You must go back to warn your people there will be war. Isn't that clear?† Absolute terror seemed paradoxically to have lent a lucidity to her thoughts and words that was entirely out of character. â€Å"Now come!† Out another way! Past officials who stared after them, but saw no reason to stop one whom only the Lord of Kalgan could stop with impunity. Guards clicked heels and presented arms when they went through doors. Arcadia breathed only on occasion through the years the trip seemed to take – yet from the first crooking of the white finger to the time she stood at the outer gate, with people and noise and traffic in the distance was only twenty-five minutes. She looked back, with a sudden frightened pity. â€Å"I†¦ I†¦ don't know why you're doing this, my lady, but thanks- What's going to happen to Uncle Homir?† â€Å"I don't know,† wailed the other. â€Å"Can't you leave? Go straight to the spaceport. Don't wait. He may be looking for you this very minute.† And still Arcadia lingered. She would be leaving Homir; and, belatedly, now that she felt the free air about her, she was suspicious. â€Å"But what do you care if he does?† Lady Callia bit her lower lip and muttered, â€Å"I can't explain to a little girl like you. It would be improper. Well, you'll be growing up and I†¦ I met Poochie when I was sixteen. I can't have you about, you know.† There was a half-ashamed hostility in her eyes. The implications froze Arcadia. She whispered: â€Å"What will he do to you when he finds out?† And she whimpered back: â€Å"I don't know,† and threw her arm to her head as she left at a half-run, back along the wide way to the mansion of the Lord of Kalgan. But for one eternal second, Arcadia still did not move, for in that last moment before Lady Callia left, Arcadia had seen something. Those frightened, frantic eyes had momentarily – flashingly – lit up with a cold amusement. A vast, inhuman amusement. It was much to see in such a quick flicker of a pair of eyes, but Arcadia had no doubt of what she saw. She was running now – running wildly – searching madly for an unoccupied public booth at which one could press a button for public conveyance. She was not running from Lord Stettin; not from him or from all the human hounds he could place at her heels – not from all his twenty-seven worlds rolled into a single gigantic phenomenon, hallooing at her shadow. She was running from a single, frail woman who had helped her escape. From a creature who had loaded her with money and jewels; who had risked her own life to save her. From an entity she knew, certainly and finally, to be a woman of the Second Foundation. An air-taxi came to a soft clicking halt in the cradle. The wind of its coming brushed against Arcadia's face and stirred at the hair beneath the softly-furred hood Callia had given her. â€Å"Where'll it be, lady?† She fought desperately to low-pitch her voice to make it not that of a child. â€Å"How many spaceports in the city?† â€Å"Two. Which one ya want?† â€Å"Which is closer?† He stared at her: â€Å"Kalgan Central, lady.† â€Å"The other one, please. I've got the money.† She had a twenty-Kalganid note in her hand. The denomination of the note made little difference to her, but the taxi-man grinned appreciatively. â€Å"Anything ya say, lady. Sky-line cabs take ya anywhere.† She cooled her cheek against the slightly musty upholstery. The lights of the city moved leisurely below her. What should she do? What should she do? It was in that moment that she knew she was a stupid, stupid little girl, away from her father, and frightened. Her eyes were full of tears, and deep down in her throat, there was a small, soundless cry that hurt her insides. She wasn't afraid that Lord Stettin would catch her. Lady Callia would see to that. Lady Callia! Old, fat, stupid, but she held on to her lord, somehow. Oh, it was clear enough, now. Everything was clear. That tea with Callia at which she had been so smart. Clever little Arcadia! Something inside Arcadia choked and hated itself. That tea had been maneuvered, and then Stettin had probably been maneuvered so that Homir was allowed to inspect the Palace after all. She, the foolish Callia, has wanted it so, and arranged to have smart little Arcadia supply a foolproof excuse, one which would arouse no suspicions in the minds of the victims, and yet involve a minimum of interference on her part. Then why was she free? Homir was a prisoner, of course- Unless- Unless she went back to the Foundation as a decoy – a decoy to lead others into the hands of†¦ of them. So she couldn't return to the Foundation- â€Å"Spaceport, lady.† The air-taxi had come to a halt. Strange! She hadn't even noticed. What a dream-world it was. â€Å"Thanks,† she pushed the bill at him without seeing anything and was stumbling out the door, then running across the springy pavement. Lights. Unconcerned men and women. Large gleaming bulletin boards, with the moving figures that followed every single spaceship that arrived and departed. Where was she going? She didn't care. She only knew that she wasn't going to the Foundation! Anywhere else at all would suit. Oh, thank Seldon, for that forgetful moment – that last split-second when Callia wearied of her act because she had to do only with a child and had let her amusement spring through. And then something else occurred to Arcadia, something that had been stirring and moving at the base of her brain ever since the flight began – something that forever killed the fourteen in her. And she knew that she must escape. That above all. Though they located every conspirator on the Foundation; though they caught her own father; she could not dared not, risk a warning. She could not risk her own life – not in the slightest – for the entire realm of Terminus. She was the most important person in the Galaxy. She was the only important person in the Galaxy. She knew that even as she stood before the ticket-machine and wondered where to go. Because in all the Galaxy, she and she alone, except for they, themselves, knew the location of the Second Foundation.

West Nile essays

West Nile essays According to the Centers for Disease Control and Prevention, claim that last year 9862 cases of West Nile Virus were reported to the CDC last year. Out of the 98 hundred cases, 2947 of them were from Colorado which is roughly 30 percent of all known cases in the United States. West Nile Virus is a dangerous disease but with the knowledge of preventive measure you minimize the likeness of infection. West Nile virus was first discovered in 1937 in the West Nile district of Uganda. New interest was created by the West Nile virus when it emerged in the United States for the first time in the New York City area in August 1999. There were 62 confirmed human cases and 7 deaths during this outbreak, creating widespread concern. WNV primarily transmitted to humans by a mosquito of the Culex species. However, according to Edward B. Hayes that West Nile virus can be transferred through blood transfusions and organ transplantation. The virus can cause encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord). Once you get bitten by the mosquito infected with West Nile Virus, there are a wide range of symptoms from showing no signs of disease to rapidly fatal brain infection. According to eMedicine.com the likelihood of a person developing illness after infection with West Nile virus is about 1 in every 140-300 people.

The symptoms of severe infection include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. In th ...

5 Tips on How to Run a Writing Group

5 Tips on How to Run a Writing Group 5 Tips on How to Run a Writing Group 5 Tips on How to Run a Writing Group By Mark Nichol You’ve got your writing group up and running. All the hard work’s over, right? Wrong. Just like any smooth-running machine, a writing group requires maintenance. Here are some tips for tender, loving care: 1. Construct Criticism Model proactive and up-front critiquing etiquette. Advise everyone to start positive with a compliment, then offer honest but objective, well-supported, and practical advice, and then conclude with another commendation. Continuously reinforce the message that no one is served when criticism is withheld; only focused, writing-centered (not writer-centered) commentary will help the writer grow. 2. Vary the Routine Some people might be ready to email a writing sample a week ahead of time to give others a chance to read and critique before the next meeting. Those selections don’t need to be read aloud before the group; you can go straight to discussion. (Hand the writer an annotated hard copy or return by email, with inserted notes, the file they sent you.) Others can pass around copies of a cold read and read it aloud while others jot down notes, then go to discussion. Yet others might simply read a shorter passage for a moment’s worth of specific advice, ask a few general questions without reading at all, or pass altogether that week, participating only in discussion about others’ work. (You may not have time to go over every group member’s project at each meeting anyway.) But don’t let any one member get away with following the same routine every time. Suggest a writing session every now and then: Everybody comes to the meeting, writes for an hour, then convenes to take turns reading part or all of their resulting selection for five minutes and getting one minute of feedback from each member. 3. Do Your Homework Establish expectations for criticism: When you read the writing of other group members, take notes, writing down questions, suggestions, and compliments. Be specific when you critique, praising a vivid description in particular or recommending more character development with detailed advice. Focus, however, not on telling others what to do but on asking questions to help them decide what to do. If you don’t understand something, or you feel that details are lacking, ask for an explanation or background information. Then, gently advise the author to incorporate their response into the narrative. Your homework also involves setting your ego aside and acting on others’ critiques. What’s the use of investing so much time and energy in this process if you don’t take feedback to heart? 4. Take a Break At regular intervals, step back from the critiquing cycle to meet just to advise or brainstorm about how to organize notes, do research, or work on character, plot, tone, and so on. Several times a year, go to a book reading together, or watch a movie or a play together and, for homework, draft a â€Å"novelization† or a rewrite of a scene and bring it to the next meeting. Compile a list of prompts for when members hit the wall. 5. Check In Periodically evaluate how the group is going. Are your meetings too often, not often enough, or just right? Too long, not long enough, or ideal? Is someone missing too many meetings or wallflowering, or does one person dominate them? Is everybody getting what they want out of the experience? What’s the procedure when somebody’s not fitting in? What do you do when one or more members drop out, or one or more members feel like increasing the number of people in the group? How do you recruit, and how do you decide whether to accept candidates? Establish and review your membership policies. Above all, remember that although the group is a democratic body that should operate by consensus, you, as the founder, must continue to moderate the proceedings and nudge everyone to always honor its principles and purposes.

Science - Assessment and Transition from KS2 to KS3 Essay

Science - Assessment and Transition from KS2 to KS3 - Essay Example Formative assessment requires the teacher to feed back to the students’ information that provides the students with opportunities to improve on their learning, or that encourages the students to reflect on their own learning (Black & Williams, 1998). In contrast to summative testing, which occurs with standardised tests, formative assessment provides in-depth, immediate and contextualised information about a student’s level of knowledge and their understanding of a particular topic (Bund & Falchikov, 2004). The reflective and engaging nature of formative assessments supports teachers in becoming better assessors, and to focus on the quality of a student’s learning and understanding, rather than the quantity of work they have undertaken (Williams, Lee, Harrison & Black, 2004). The sole use of summative testing results in teachers being ignorant of the true understandings, strengths and weaknesses of their students. Formative assessment can aid in narrowing the gap between high and low achievers in the classroom (Black & Williams, 1998). The use of formative assessment requires a learner-centered approach to teaching, as the student is the end user of the assessment information (Bund & Falchikov, 2004). Effective formative assessment focuses on feedback regarding scientific tasks, and not the student. Hence, feedback focuses on the particular qualities of the student’s work, with suggestions for improvements, and without comparisons to classmates (Black & Williams, 1998). The ideal form of this requires that the student develop the ability for ‘self-assessment’, which allows them to demonstrate their understanding of the goal of the task and their learning (Williams et al., 2004). The KS3 teacher could utilize formative assessment strategies to determine the level of knowledge and understanding of science for student’s at the beginning of the year. Procedures for self-assessment, or peer-assessment, could include the use of ‘Traffic Lights’

Assignment - Essay Example The steles also have various heights. The placements create paths that are narrow and can only accommodate one person at a time. The unevenness of the steles reminds the viewers of the scattering of the Jews throughout the world. Unlike the small statues dedicated to the Jews, this Memorial is larger like those found at the actual camps. It is a massive reminder of the devastation the Holocaust cost not only the Jews, but the German people as a whole. Many people were involved with this project. Richard Serra started off the project, but quit over artistic differences. Lea Rosh, a journalist, wanted a visible memorial for the Holocaust. In Germany, the Holocaust was a shameful topic. The Germans did not want to speak of the past. Different governments backed and stalled the project. Finally the project was funded in 1999. Eisenman wanted to honor victims first, but make Germany as a whole remember the atrocities of the Third Reich for future generations. Instead of a small memorial, he created a large area that cannot be ignored by Berliners. Unlike their ancestors, Berliners today and in the future will not be able to turn away from the ugly truth. The Holocaust happened and needs to be
