X-ray Documented - Essay Example This means that materials science and engineering operates in a world characterized by high technological advances because technological advancements created from advanced materials. The significance of materials science and engineering started a long time ago. It has existed for many years. Nowadays, people only look at the names of eras and realize that materials have been helpful in the creation of civilization. These eras include the Stone Age, the Bronze Age and the Iron Age. In fact, people have branded the current era as the material era because of the contribution that material engineering has provided. X-rays use materials that are provided by the technology in material science and engineering. The history of the development of science and technology has always been directly linked to the progress of materials science and engineering. In recent times, the expansion of concentration in the surface qualities of solids has become a feature of this field of knowledge. Neverthele ss, it is not surprising that interactions with material are realized through the free surface of the materials. Surface layers can unfalteringly control the application of the whole quantity of material. The free surface is essential for a large amount of material and mechanical features of materials that include yield strength, proportionality limit and material behavior in processes of fragile and low energy fracture (Sham 1012). The concept of X-rays was first discovered by a physicist from Germany called Wilhelm Roentgen in 1895. However, A.W. Goodspeed was the first person to make the X-ray discovery, on February 22, 1890. Because there was no information that could prove that he had discovered X-ray, Goodspeed named his discovery an accident and did not take any credit for the work he had done (Dyson 1). In the discovery, Wilhelm enclosed a glass tube inside of a black paper box. He attached a wiring that ran inside the glass tube that resembled the inside of a light bulb. Th is enabled the electrical currents to build up in the glass tube. He then connected the tube to an induction coil apparatus that allowed an electric current to pass through the tube. This way, a faint green colored light could be seen across the room. He decided to do this in a different way to be sure of what he had seen. He lit a match stick and discovered that there was a small screen in the room which was coated with a chemical. The lighting from the match stick sent the current along the tube. This made the exact same light to appear again. As he continued with his experiments, he discovered that these rays could penetrate through objects, such as wood and metal. Accidentally, his hand came in contact with the tube one day, and saw shadows of his hand with darker shadows that represented the bones. When he moved his hand, the shadow on the screen also moved. He named the shadow the first x-ray picture (Lewin, Paradijs and Heuvel 373). X-ray works in a unique way. As the wavelen gths of light diminish, they augment in terms of the energy that is produced. X-rays have lesser wavelengths, which cause higher energy compared to ultraviolet waves. This is the reason as to why professionals consider X-rays with respect to the energy they produce rather than their wavelength. This is partly because X-rays have minute wavelengths. Another reason is because X-ray light works like particles as opposed to waves. X-ray detectors gather definite photons of X-ray light that are remarkably different from the radio telescopes that contain large tableware designed to focus radio waves. When an X-ray of a person’s body is done in a hospital, professionals put X-ray sensitive films on one side of the patient’

Cloning Brachyury from SW480 in pNEB193 plasmid Essay - 3

Cloning Brachyury from SW480 in pNEB193 plasmid - Essay Example igure 2: The total RNA was extracted from SW480 cells by use of Norgen’s Total RNA Purification Kit, the samples were then denatured in rapid Formalin – free RNA loading buffer which had Formalin – Free RNA dye. They were then incubated for 5 minutes at a temperature of 700C. Lane number one was filled with RNA ladder 5 ÃŽ ¼L. The lanes from number 2 to 20 contained 10 ÃŽ ¼L of each of the class samples. The image capture was then done using GelDocEZ system. 3-Table 1: The concentration and purity of the total extracted RNA from the SW480 cells for the sample H was is shown in table 1. The resulting concentration of RNA was 82.88 ng/ul. An RQI of 7.3 indicated that the RNA quality was accepted. The ratio (28S/18S) was 0.93 though the recommended ratio is 2 The plasmid preparation experiment was undertaken before the start of the RNA extraction. The purpose of this experiment was to purify enough linearized phosphatise treated pNEB183 plasmid to be utilised in the ligation reaction. This purification was attained through several steps that started with the purification of the inoculated plasmid from E.coli culture in LB/ampilicin broth. Using Qubit analysis, the concentration of the purified plasmid was calculated to be 5.1 ul. The EcoR1 enzyme was then utilised to digest the circular plasmid into a linear plasmid which was then treated using alkaline phosphatise enzyme to remove the 5’ phosphate group and hinder self – ligation. The sample was then loaded on 0.8% agarose gel so as to visualize and purify the linearized plasmid from the gel by use of purification method as shown in figure 5: In figure 5, two bands were clearly seen in the second lane. The first band was an uncut plasmid. The second band was a linear plasmid. Adequate preparation took place as the linear plasmid could migrate longer on the gel. The second band was bright and shiny. It was 2797 bps in length. It also contained ...ul/mg concentration of plasmid. Using x tracta Gel Extraction

Music Styles Comparative Essay Essay The first artist/composer is Johann Chrysostom Wolfgang, who is better known as Wolfgang Amadeus Mozart but around the world he just known as Mozart. Mozart is such a ‘famous’ composer as throughout the classical era (1750-1820) although he may not have been recognized at the time he was a creative and influential composer. Not many could argue that a man who composed over six hundred works was not influential. Also many of those six hundred works were acknowledged as the peak of symphonic, concertante, chamber, piano, operatic, and choral music. You can now start to see why he was such a significant composer. The second artist/composer is Ludwig van Beethoven, otherwise referred to as simply Beethoven. Beethoven was considered a German composer and pianist. Similarly to Mozart he began his musical career in the classical era (1750-1820) but differently to Mozart he was a crucial figure within the transitional stage between the Classical and Romantic eras in western classical music.

Company Law problem question: Running a business

Company Law problem question: Running a business Company Law problem question Question 1(a) Tom, Dick and Harry are in business together in the form of a legal partnership. The business having developed somewhat, they are now keen to incorporate their business into a limited company. This will undoubtedly have benefits for the traders, although there are of course certain ramifications of which they should be aware which will be dealt with after a discussion of the benefits of incorporating. The correct choice of business medium is a crucial decision for any business. It will affect how the business trades, the liability of those running the business (in their guise of partners or directors) and the liabilities of the business itself for taxation, for example, in the case of a company. Perhaps the most significant concern for Tom, Dick and Harry, is the risk of capital that is associated with any business. The overwhelming benefit in this context of forming a limited company over remaining as a partnership is that a company will carry only limited liability. This means that the owners of the company (that is, Tom, Dick and Harry, assuming they remain as directors and become shareholders) will only be liable for the amount of unpaid shares in the company if the company were to become insolvent or even bankrupt. In other words, they can choose the amount which they are willing to pay into the company (which does not have to be paid up front), and this is the total amount f or which they would be liable should the company ever be wound up. This can be contrasted with the situation under a partnership where the partners would be both jointly and severally liable for the entire value of their trading losses. This means a partner could lose any property that he owns. The beneficial effects of this arrangement would be limited, however, in a number of situations. If Tom Dick and Harry were to risk everything in the business, that is, if they invest all there assets in the business, then they would still lose it all if the company were to become insolvent. Secondly, it is often the case that when a company comes to borrow money for business development, and particularly where the company is relatively new and unknown to the banks, that the lenders will demand personal guarantees for the value of the loan on top of the normal contractual and security relations with the company. These would, obviously, override the limited liability associated with the company. As business is good for Tom, Dick and Harry at the moment, however, this would not appear to be an immediate problem. A further issue to be considered when deciding whether to incorporate as a company is the expense involved. While these are not extortionate, they are, at least, significant, and should be duly considered by Tom, Dick and Harry. Unlike a partnership, a company needs to be registered, which incurs fees itself. There will be legal fees payable to the solicitor who draws up the new company’s memorandum and articles of association (together, the constitutional documents of the company), which are essential, and outline the aims, methods, and rules of the company’s business life. A similar issue of expense and complexity that will be incurred by a company as opposed to a partnership relates to the accounts of the company. While all businesses, including partnerships, obviously wish to keep accounts, the requirements for accounting for companies are more particular and complicated. The accounts need to be more detailed, and show certain information in a particular way. Furthermore, because companies are subject to more rigorous regulation, the accounts of a company will need to be audited annually by an independent qualified accountant. This, of course, will incur higher accountancy costs that would be expected for a partnership. The company will also be required to complete an annual return and pay a fee on filing it with the Registrar. A company is subject to certain rules and regulations relating to its operation and management, which are statutorily set out in the Companies Act 1985 (subject to be overhauled when the current Company Reform Bill makes it through Parliament). An example of this is the requirement that a company must have at least one director and one secretary. It is usual for the first owners (Tom, Dick and Harry) to become the first directors and / or secretary. These officials will have certain obligations relating to duties owed to the company, and in respect of items that need to be completed and filed with the Registrar of companies at Companies House. An important consideration to take into account is the flexibility of a company to change its internal structure if and when circumstances require it. Such a change would normally involve and require an alteration to the company’s articles of association. This would require, under the Companies Act, a so-called ‘special resolution’, which equates to 75% of the shareholders. In the case of Tom, Dick and Harry, if they were to remain the only shareholders, any such decision would, of course, have to be unanimous. If any conflict is predicted, this will have to be a consideration for the parties. It is worth noting that this requirement is no more stringent than that required for altering a partnership agreement, which requires the approval of all partners. If a conflict were to arise between the directors of the company, the other shareholders would be able to remove the troublesome director by way of an ordinary resolution. Finally, the legal status of a company differs significantly from that of a partnership. A company is seen as a separate legal person, which means it can contract and be held liable in its own name. This has ramifications for the liability of the directors, and is generally seen as a benefit of a company. Only a company (and not a partnership) can create floating charges over their assets. This is significant when it comes to raising finance by way of granting security. It will probably be easier for a company to raise the requisite finance than for a partnership to do so. It is also significant (or may be) that an unlimited number of people can become members of a company, whereas a partnership is limited to twenty partners. If and when the company grows and develops, it will be in its interests to be unlimited in the number of new members it can obtain. Question 1(b) In this scenario, there are a number of developments which will impact on the running and management of the business. Each development will be taken in turn. Firstly, the sale of the company’s property to Dick’s sister, Fanny in 2006 will be problematic. There are three principal areas of concern. Firstly, the company’s articles of association expressly prohibit the sale of company property without a special resolution of the members. As was mentioned above, a special resolution requires a 75% majority, or in this case, as there are only three members, a unanimous vote. There is a course of action that the directors can take, however, after the event, that could ratify the sale of the company property. They will simply need to call an extraordinary general meeting, following the correct procedure of course, and pass a special resolution either to ratify the sale of the company property to Fanny, or else to alter the articles of association to allow for such sales in a more general context. The value and size of the property that is sold to Fanny will be significant in the second area of concern for the company. Under section 320 of the CA, ‘a company shall not enter into an arrangement whereby a director of the company or its holding company, or a person connected with such a director, acquires or is to acquire one or more non-cash assets of the requisite value from the company†¦unless the arrangement is first approved by a resolution of the company in general meeting.’ The reason the value of the property that is transferred to Fanny is significant is because of the existence of the concept of ‘requisite value’, which is set down in section 320(2). This states that the requisite value for a non-cash asset is  £100,000 or 10% of the company’s asset value. If the property is of this value or greater, then, it will be of the requisite value, and will contravene section 320. The fact that Fanny (the purchaser) is the sister of a dir ector classes her as a ‘connected person’. As such, she breaches the section 320 prohibition. Finally, the gross undervaluing of the property in the company’s sale of it to Fanny will be a problem, as it is likely that this will breach section 339 CA in the case of the company becoming insolvent. Were this to happen, the insolvency practitioner would likely deem the transaction to be voidable, and the asset would be brought back into the pool of the company’s assets in order to satisfy the creditors. This would occur if the transaction occurred within 5 years of the presentation of the petition for winding up (because Fanny, again, is an ‘associate’ of the transferor). Under section 238 defines a transaction at an undervalue as one where a company makes a gift to any person and receives either no consideration for it or consideration worth significantly less than the consideration provided by the company. This transaction clearly qualifies as such. It will be deemed to be set aside if insolvency proceedings commence within two years of the transacti on. Each of the directors’ decisions will now be addressed. They decide, firstly, to enter a contract with Oui Ltd. This is not, of course, a problem in itself, apart from the fact that Tom is a director of Oui Ltd. Firstly, if entry into the contract was ratified by an ordinary resolution in the company, Tom would not have been able to vote on it under section 94, because he has an interest in it. If Dry Ltd have adopted Table A articles of association, this would be confirmed by article 94. The company should have kept a register of its directors, which lists the interests and other directorships of all its directors (under section 288 CA), which would have detailed Tom’s directorship of Oui Ltd. Furthermore, section 317 CA requires Tom to have declared his interest in the proposed contract with Oui Ltd at a board meeting of Dry Ltd. He should have given general notice of his directorship. The company issues a further 10,000 unpaid shares to a third party to fight off a takeover bid. This should not create a problem so long as the company’s articles of association give the directors power to issue shares. This in turn is dependent on the company having a sufficient amount of unissued authorised share capital. If it does not, a special resolution will need to be passed to increase this authorised share capital, before passing a further resolution allowing the issue. The powers of the directors in this instance are regulated by section 80 CA. Furthermore, the company must, under section 89, give consideration to rights of pre-emption to existing shareholders. As the directors are the only three shareholders, this should not be a problem, but it would mean they had to wait 21 days before issuing the new shares. The resignation of David and his formation of Whip Ltd, which obtains the contract from Pop Ltd might breach his director’s service contract with Dry Ltd. It is usual for such contracts to contain a clause prohibiting former directors using their business contacts within a certain time of leaving the former directorship; a non-solicitation clause. This would protect Dry Ltd’s business links. Given Harry’s age and his mental deterioration, the company will be able, if it has the heart, to remove him from office following the procedure for removal of directors set down in section 303 CA, which requires an ordinary resolution to be passed. Harry may be able to claim damages for his removal from office under this procedure.

A Consumers Buying Behaviour Essay examples -- Consumer Business Mark

A Consumer's Buying Behavior A consumer's buyer behavior is influenced by four major factors; cultural, social, personal, and psychological factors. These factors cause consumers to develop product and brand preferences. Although many of these factors cannot be directly controlled by marketers, understanding of their impact is essential as marketing mix strategies can be developed to appeal to the preferences of the target market. When purchasing any product, a consumer goes through a decision process. This process consists of up to five stages; problem recognition, information search, evaluation of alternatives, purchase decision and post purchase behavior. The length of this decision process will vary, ranging from a shorter routine response behavior, to limited problem solving and a more comprehensive extensive problem solving. A consumer may not act in isolation in the purchase, but rather may be influenced by any of several people in various roles. The number of people involved in the buying decision increases with the level of involvement and complexity of the buying decision behavior. Consumers buyer behavior and the resulting purchase decision is strongly influenced by cultural, social, personal and psychological characteristics. An understanding of the influence of these factors is essential for marketers in order to develop suitable marketing mixes to appeal to the target customer. CULTURAL factors include a consumers culture, subculture and social c...

Globalization is made up of social, economical, technological, heritage, and political alterations that display interdependence and development. Globalization rises the benchmark of living in nations, broadens technological information, and heightens political liberation. The major origin of globalization is the leverage from other nations. Globalization is a method that outcomes from human change and technological development. The communal effects of globalization are apparently illustrated in Peru. Once a third-world homeland topped up with scarcity and oppression, Peru is now transitioning into a evolved nation. In Peru, globalization has increased the human development index, empowered women, and conceived a more powerful country. One of the advantages of globalization on a communal grade is an increased Human Development Index. The Human Development catalogue is a estimation of a country's communal, political, and economical development in comparison to other countries in the world. The Human Development catalogue rates each country with a tally between 0 and 1, with 1 being the most advanced, globalized homeland. components that are engaged in determining a country's HDI are gross household output per capita, life expectancy at birth, mature person scholarly, and the number of persons enrolled in informative organizations. In 1975, Peru's Human Development catalogue was a 0.643. By 2003, the Human Development catalogue had risen more than one tenth to 0.762. The substantial boost of Peru's HDI is a clear indication that globalization has made a affirmative influence. From 1975 until 2003, globalization has caused a 2% boost in the adult literacy rate. throughout the same time time span, the scarcity rate to fallen 6%. Wom... ... more mighty that person is. Those persons desire to have the wealthy get more affluent and the poor become even poorer, so they are probably against globalization. Whereas globalization may not be the flawless answer to end all of the world's difficulties, it is a good start. Countries that adopt globalization, such as Peru, have benefited tremendously. Globalization is good for a country's finances, politics, and most significantly for its persons. Peru was one time a third-world country ravaged with poverty, oppression, and a need of learning. Globalization has contributed to the decrease of scarcity, bigger literacy rate, and the liberation of women in Peru. The consequences of globalization can be identified in Peru and all around the world, when technological information is disperse, free trade is boosted, and political or social liberation is accomplished.

Turn of the Screw

Claire Carlson English 3H February 7, 2013 Period 1 Spring Essay: Turn of the Screw Page I: The Governess and Miles Page II: The Governess and Mrs. Grose Page III: Corruption of Innocence Henry James’s Turn of the Screw is the eerie tale of a governess sent to care for two mischievous young children, Flora and Miles. Many people mistake it for a ghost story, but the story actually focuses more on the governess’s relationship with the children. Her thirst for acceptance gradually grows as the story progresses, and she becomes especially fascinated with Miles.Women have always been viewed as slightly inferior to men; they are depicted as weak and fragile creatures, only serving as a companion for man. They are manipulative and often use charm and looks as methods of persuasion. In Turn of the Screw, the governess ‘s attitude while around Miles is flirtatious and almost inappropriate; and she uses him to fill the void of the children’s beloved uncle whom she l usts for. The above example of the governess’s craving for Miles’s attention can be easily compared to the behavior exhibited by much of the female population today.Note that the woman is always seeking to please the man, and strives to satisfy and serve him. The attitude of women in the modern world is becoming more and more submissive; almost voluntarily. Miles’s reaction to the behavior of the unnamed governess is merely compliant, and in some instances of the novel he somewhat encourages her inappropriate behavior. Mrs. Grose, the simpleminded and somewhat slow housekeeper at the estate, represents a middle ground between the mischievous children and whimsical governess. The reader can easily conclude that the governess abuses Mrs.Grose’s quite malleable opinion of the children. In several instances, the governess consults Mrs. Grose and uses her as an outlet for her frustrations with the children. As the governess shares her ghostly encounters with Q uint and Miss Jessel, she convinces Mrs. Grose that her hysteria is justified. Since Mrs. Grose is not significantly talkative, it is difficult to form a conclusion about her opinion of the children and the governess. The reader has to infer that Mrs. Grose has spent quite some time at the estate, and has much experience with the children’s behavior. Mrs.Grose doesn’t necessarily agree or disagree with the statements and assertions made by the governess, she is merely a cache, storing the governess’s thoughts and responding with uncomprehending feedback. The children’s relationship with Mrs. Grose is somewhat distant and peculiar. They only consult her for affirmation and approval. In conclusion, Mrs. Grose is mainly an unresponsive character and is not a major influence on the circumstances of the story. Since the governess seldom approaches the children directly, we can infer that she would rather keep her knowledge of Quint and Jessel to herself.She of ten consults Mrs. Grose in order to gather as much as she can about the two. The governess is afraid that the children know too much, and fears that their knowledge of Quint and Jessel’s sexual relationship will affect them negatively. The fact that she is more concerned about the children knowing too much rather than protecting them from the possible harm that the ghosts can inflict, shows the reader that the governess incorporates her own fears and desires into the situation. In conclusion, Turn of the Screw is a much more complex and confusing story than meets the eye.The reader must question the behavior of the governess and the children in order to gather valuable information about the ghosts, and it seems as though in certain instances that Quint and Jessel are living through Flora and Miles. The governess is indeed a much more questionable character than the book portrays her to be. From my experience with both the book and a movie interpretation of the book, I have co ncluded that the governess is actually the main source of the hysteria and trauma at Bly.
