The History Behind Who Invented HTML

The History Behind Who Invented HTML Some of the people who drive the transformation of the internet are well-known: think Bill Gates and Steve Jobs. But those who developed its inner workings are often totally unknown, anonymous, and unsung in an age of hyper-information that they themselves helped to create. Definition of HTML HTML is the authoring language used to create documents on the web. It  is used to define the structure and layout of a  web page, how a page looks, and any special functions. HTML does this by using what are called tags that have attributes. For example, p means a paragraph break. As the viewer of a web page, you dont see HTML; it is hidden from your view. You see only the results. Vannevar Bush Vannevar Bush was an engineer born at the end of the 19th century. By the 1930s he was working on analog computers and in 1945 wrote the article As We May Think, published in the Atlantic Monthly. In it, he describes a machine he called memex, which would store and retrieve information via microfilm. It would consist of screens (monitors), a keyboard, buttons, and levers. The system he discussed in this article is very similar to HTML, and he called the links between various pieces of information associative trails. This article and theory laid the foundation for Tim Berners-Lee and others to invent the World Wide Web, HTML (hypertext markup language), HTTP (HyperText Transfer Protocol), and URLs (Universal Resource Locators) in 1990. Bush died in 1974 before the web existed or the internet became widely known, but his discoveries were seminal. Tim Berners-Lee and HTML Tim Berners-Lee, a scientist and academic, was the primary author of HTML, with the assistance of his colleagues at CERN, an international scientific organization based in Geneva. Berners-Lee invented the World Wide Web in 1989 at CERN. He was named one of Time magazines 100 most important people of the 20th century for this accomplishment. Berners-Lees browser editor was developed in 1991-92. This was a true browser editor for the first version of HTML and ran on a NeXt workstation. Implemented in Objective-C, it, made it easy to create, view, and edit web documents. The first version of HTML was formally published in June 1993.

Financial Resource Management - Essay Example With the help of trade goods are made available to consumers at the time of their need. It removes the hindrance of persons by bringing together producers and consumers who are widely scattered. Financing is of two types, equity financing and debt financing. When you are in need of money or looking for capital, company's debt-to-equity-ratio should be considered. It is the relations between the Dollars or Euros that an entrepreneur has borrowed and Dollars or Euros invested in the business. The more the investment by the owners the more they attract the financing. When the equity to debt ratio of the firm is high then debt financing should be taken. If the proportion of the debt to equity ratio of the firm is high then it is advised that the owners should increase their equity investment, that way they cannot jeopardize firm's survival. Limited equity financing is used by most of the small or growth stage businesses. Whereas in debt financing, funds pour in from different quarters like from friends, relatives, etc. Venture capitalists are the most common source of equity funding. Venture capitalists may be institutional risk takers, financial institutions, wealthy persons, etc. and most of them specialize in industries. Venture capitalists are risk takers and show interest only in three to five year old companies that result in more than average profits. These venture capitalists are called as investment gurus whose interest lies in those companies that have major regional and national concerns. Debt Financing Commercial finance companies, financial institutions, banks, savings and loans, Lloyds Bank small business, etc. are some of the sources for debt financing. Because of their positive impact on the whole economy local and state government encourage the growth of the small companies. In debt financing additional funds comes from friends, family, relatives, and industry colleagues, etc when capital investment is smaller. Generally banks formed as a major source for loans for the establishment of small businesses. Banks don't offer long term loans to small firms instead they grant short term loans for machinery and

Leadership Models Essay Example | Topics and Well Written Essays - 1250 words

Leadership Models - Essay Example Situational contingency theories have are organizational development application that are effective at applying leadership concepts that are adaptive to the situation at hand. There are three major situation contingency models. The three models are Fielder’s leadership model, House’s path – goal theory of leadership, and Hersey and Blanchard’s situational leadership model. The Hersey – Blanchard leadership model framework implies that there is no one single best way to approach a problem or situation. According to Hersey and Blanchard situational leadership requires adjusting the leader’s emphasis on task behaviors such as giving guidance and direction, relationship behaviors, and providing socio-emotional support (Schermerhorn, J., Hunt, J., Osborn, R., 2003). The leadership style application has become very popular in the 21st century due to the fact that business changes are occurring faster than ever and manager have to be adapt the busin ess strategy of the company and the vision of its human resources to meet the market demands and requirements. The Blanchard and Hersey model can be characterized in terms of the amount of direction and support that the leader gives to his or her followers (12manage, 2009). Appendix A illustrates a matrix that explains the functionality of the model. The four factors illustrated in each quadrant of the matrix are S1, S2, S3, S4. The S1 variable which is located in the bottom left quadrant represents the telling style. In this style the manager provides a high task low relationship work output. This means that manager provides specific instructions and closely supervises the performance of the subordinate. This style is most effective when the leader is dealing with employees that are unable to take responsibility for themselves. An example of an employee that needs his supervisor to apply a telling style is a new employee in a firm. This person needs more

Final Exam in Principles of Sociology - Essay Example The lungs of the asthma patients shrink considerably, and when they breathe they feel like ‘breathing through a straw’. Stratification makes it difficult for many asthma patients to receive timely health care and many low income class people find it almost impossible to afford effective treatments for the disease. The huge amount of money spent on medical treatment and medical bills make it impossible for them to have other necessities of life such as good hosing and healthy living conditions. All these add to their personal troubles and miseries. An understanding of Mills’ perception of the sociological imagination is important in understanding the macro-level forces that contribute to public issues like asthma. Mills perceives sociological imagination as a way of thinking that believes that human behavior is shaped through social interaction; according to him, one’s personal experiences are always linked to the social contexts such as the prevailing milieu, the connection between history and biography, and the realization that one’s personal troubles are often the results of public issues of social culture. He believes that the sociological imagination would enable one to â€Å"understand the larger historical scene in terms of its meaning from the inner life and the external career of a variety of individuals† (Cargan & Ballantine 30). The social forces that contribute to asthma are the unequal distribution of power and income, the psychological and social constraints that the asthma patients ar e subject to in the American society. While medical practitioners hold that asthma can be prevented through â€Å"right medication, clean air, and a reasonably stress-free life†, many low-income asthma patients feel that this is â€Å"both well-intentioned and useless† (Corbett 59). The low-income asthma patients are very often unable to pay the huge amount of medical bills and these unpaid medical bills cause mental and psychological

Effect of Zn Concentration on NiZnFe2O4 Nanoparticles

Effect of Zn Concentration on NiZnFe2O4 Nanoparticles CHAPTER-7 EFFECT OF Zn CONCENTRATION ON MAGNETIC AND DIELECTRIC PROPERTIES OF NiZnFe2O4 NANOPARTICLES 7.1 INTRODUCTION Ni (1-x) Zn (x) Fe2O4 (x=0.2, 0.4 and 0.6) nanoparticles are synthesized by using coprecipitation method. Zinc is a known metal, its role is important in the modification of ferrite properties by redistribution over the tetrahedral and octahedral sites of the spinel lattice. Rath et al (2002) reported the effect of zinc substitution on lattice parameter and magnetic properties on Mn-Zn ferrites prepared by hydrothermal precipitation method. Arulmurugan et al (2005) studied the effect of zinc substitution on Co-Zn and Mn-Zn ferrite nanoparticles prepared by coprecipitaion method. This chapter discusses the effect of zinc concentration on structural, magnetic and dielectric properties of NiZnFe2O4 nanoparticles prepared by co-precipitation method. The detailed experimental procedure involved in the preparation of NiZn ferrite nanoparticles has been already reported in chapter IV. In this method three different compositions such as x=0.2, x=0.4 and x=0.6 were used in the chemical formula Ni (1-x) Zn(x) Fe2O4 to analyze the properties of the ferrite nanoparticles. 7.2 RESULTS AND DISCUSSION 7.2.1 X-ray Diffraction (XRD) analysis The average crystallite size ‘t’ and the lattice parameter ‘a’ were calculated from X-ray diffraction data as reported in the chapter –IV. The values of particle size and Lattice parameter of all samples are also tabulated in Tables 7.1, 7.2 and 7.3. The particle size decreased from 24 to 12nm with the increase of Zn concentration. The same behavior of decrease in particle size with the increase of zinc concentration was also observed for the samples sintered at 600 °C and 900 °C. The decrease in particle size due to the increase of zinc concentration was 26 to 20nm for sintered sample at 600 °C and 31 to 25 nm for sintered sample at 900 °C respectively. This variation of particle size with zinc concentration at the above mentioned sintering temperature of Ni Zn ferrites nano particles is shown in Fig.7.1. The above observation shows that the presence of zinc blocks the grain growth. The surface temperature affects the molecular concentration at the surface of the crystal, and hence, the crystal growth (Upadhyay et at 2004). The formation of Zn-ferrite is more exothermic as compared with the formation of Ni-ferrite (Navrotsky Kleppa 1968). Thus, the crystal surface temperature increases with addition of zinc, decreasing the molecular concentration at the crystal surface and hence, obstructing the grain growth. The effects of zinc concentration on structural, magnetic and dielectric properties of Ni-Zn ferrite nano particles were studied. Particle size decreased with the increase of concentration. This decreasing in particle size behavior was observed for all the categories of concentration variation at different sintering temperature levels. The effect of zinc concentration on particle size showed a reverse effect compared with the effect of sintering temperature (chapter-IV), in which the particle sizes increased with the increase of sintering temperature. Table 7.1Particle size and Lattice parameter of as prepared Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles Table 7.2 Particle size and Lattice parameter of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 600 °C Table 7.3 Particle size and Lattice parameter of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 900 °C From Tables 7.1, 7.2 and 7.3 it is also observed that the lattice parameter increases with the increase of zinc concentration. The lattice parameter value for as prepared are increased from 8.33 to 8.37Ã… with the increase of zinc. For the samples sintered at 600 °C the lattice parameter value for lower zinc concentration (x=0.2) is 8.63Ã… and higher zinc concentration (x=0.6) is 8.66 Ã…. The similar behavior of increase in lattice parameter with zinc concentration is also observed as 8.64 to 8.68 Ã… in the samples sintered at 900 °C. This increase of lattice parameter with zinc concentration for all sintering temperatures of Ni Zn ferrites nano particles are also shown in Fig.7.2. The addition of Zn2+ in Ni-ferrite causes the Fe3+ ions to migrate from A site to B site. The larger ionic radius of zinc (0.82Ã…), compared with ferric ion (0.67 Ã…), makes the A site and thus the lattice expands, increasing the lattice parameter. A similar variation of particle size and lattice parameter with zinc content had been observed by Joshi Kulkarrni (1986) for Mg-Zn Ferrite. Fig.7.1Variation of particle size with zinc concentration for all sintering temperatures Fig.7.2Variation of lattice parameter with zinc concentration for all sintering temperature 7.2.2 Magnetic Properties The room temperature B-H hysteresis loops of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) sintered at 600 °C and 900 °C are shown in Figs.7.3 (a), 7.3 (b) and 7.3 (c). The variations of magnetic properties such as saturation magnetization (Ms), and coercivity (Hc) for different zinc concentrations (x = 0.2, 0.4 and 0.6) at particular sintering temperature were calculated from the hysteresis data and tabulated in Tables 7.4, 7.5 and 7.6. Table 7.4 Saturation magnetization and coercivity values of as prepared Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles Table 7.5 Saturation magnetization and coercivity values of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 600 °C Table 7.6 Saturation magnetization and coercivity values of Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles sintered at 900 °C The effect of zinc concentration on magnetic properties such as saturation magnetization and coercivity of all compositions of Ni Zn ferrite nano particles sintered at 600 °C and 900 °C are shown in Figs.7.4 and 7.5. The Fig.7.4 reveals that the saturation magnetization (Ms) decreases with the increase of zinc concentration. The saturation magnetization value decreased from 29.73 to 6.98 emu/g with the increase of zinc concentration for as prepared samples. The saturation magnetization value for the 600 °C sintered samples at lower zinc concentration (x=0.2) was 32.78 emu/g and higher zinc concentration (x=0.6) was 25.80 emu/g. A similar behavior of decrease in saturation magnetization with zinc concentration was also observed in the samples sintered at 900 °C as 64.34 to 39.50 emu/g. Fig.7.3 Hysteresis loops of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) (a) as prepared (b) 600 °C sintered (c) 900 °C sintered samples This decreasing of saturation magnetization with the increase of non magnetic Zn concentration is due to the interaction created by the zinc in the tetrahedral and octahedral sites. This shows the weakening of A-B interaction, whereas B-B interaction changes from ferromagnetic to antiferromagnetic state. The occurrence of minor decrease in saturation magnetization is also evidenced from the dielectric study, because it shows that there is a minor increase in dielectric constant. This reason leads to the conclusion that saturation magnetization variation with respect to concentration for 600 °C and 900 °C samples did not cause a rapid decrease in saturation magnetization like as prepared sample. Fig.7.5 shows that the coercivity values of NiZn ferrite nanoparticles decrease with the increase of zinc concentration. The coercivity values of as prepared nanoparticles decrease from 324.36 to 306.56 Gauss. Similarly the variation of coercivity values of nanocrystalline NiZn ferrite particles with increase of Zn concentration sintered at 600 °C and 900 °C are in the range of 347.31- 340.72 Gauss and 386.67-351.34 Gauss. This is due to the decreases of magneto crystalline anisotropy constant. The magneto crystalline anisotropy constant is negative for both Ni and Zn ferrites. The absolute value of magneto crystalline anisotropy constant larger for Ni ferrites than that of Zn ferrites (Verma et al 2000). The total anisotropy is equal to the sum of their individual anisotropy. So magneto crystalline anisotropy constant and hence coercivity decreases with the increase in Zn concentration. Also reasons behind the decrease in saturation magnetization and decrease in coercivity are c learly identified from the formation of smaller particle size even at the higher Zn concentration at all sintering temperatures. Fig.7.4 Variation of saturation magnetization with zinc concentration Fig.7.5 Variation of coercivity with zinc concentration 7.2.3 Dielectric properties The effect of zinc concentration on dielectric constant of all samples of Ni (1-x) Zn (x) Fe2 O4 nano particles are shown in Figs.7.6 (a), 7.6 (b) and 7.6 (c). The values of dielectric constant and dielectric loss are tabulated in Tables 7.7, 7.8 and 7.9. Fig.7.6 Dielectric constant curves of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) (a) as prepared (b) 600 °C sintered (c) 900 °C sintered samples Fig. 7.7 Dielectric loss curves of Ni (1-x) Zn (x) Fe2 O4 nano particles for different zinc concentration (x = 0.2, 0.4 and 0.6) (a) as prepared (b) 600 °C sintered (c) 900 °C sintered samples The dielectric constant attained for zinc concentration x =0.6 led to a higher value for all the samples. The variations of dielectric constant with zinc concentration for all samples are also shown in Fig. 7.8. For all as prepared samples, the dielectric constant value increased from 10.92 to 25.08 with the increase of zinc concentration. The dielectric constant value for the samples sintered at 600 °C in lower zinc concentration (x=0.2) was 15.33 and it increased to 32.86 at higher zinc concentration (x=0.6). A similar behavior of increase in dielectric constant with increase in zinc concentration was also observed in the samples sintered at 900 °C as 19.37 to 48.18. Table 7.7 Dielectric constant and Dielectric loss values as prepared Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles Table 7.8 Dielectric constant and Dielectric loss values of  Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles  sintered at 600 °C Table 7.9 Dielectric constant and Dielectric loss values of  Ni (1-x) Zn (x) Fe2O4 (x= 0.2, 0.4 and 0.6) nano particles  sintered at 900 °C Figs.7.7 (a), 7.7 (b) and 7.3 (c) show the effect on zinc concentration on dielectric loss factor of all samples of Ni (1-x) Zn (x) Fe2 O4 nano particles. The variation of dielectric loss factor value with zinc concentration for all sintering temperatures is also shown in Fig. 7.9. For all as prepared samples the dielectric loss factor value increased from 0.59 to 1.36 with the increase of zinc concentration. For the samples sintered at 600 °C the dielectric loss factor value for lower zinc concentration (x=0.2) was 0.68 and at higher zinc concentration (x=0.6) it was 1.61. A similar behavior of increase in dielectric loss with increase in zinc concentration was also observed in the samples sintered at 900 °C as 1.34 to 2.14. In Ni-Zn ferrites Zn occupies [A] site and Ni occupies [B]site, while Fe occupies both [A] and [B] sites. When Zn2+ is added in the place of Ni2+, with increase in Zn composition x, some of the Fe3+ ions get converted into Fe2+ ions. This increases the hopping between Fe3+ and Fe2+ ions, thereby decreasing the resistance of the grain. This increases the probability of electrons reaching the grain boundary. Hence the polarization and the dielectric constant increase. Fig.7.8 Variation of dielectric constant with zinc concentration Fig.7.9 Variation of dielectric loss with zinc concentration 7.3 CONCLUSION The effects of zinc concentration on structural, magnetic and dielectric properties of Ni-Zn ferrite nano particles were studied. The increase in zinc concentration obstructed the grain growth and decreased the particles size. The larger ionic radius of Zn, increased the lattice parameter values of NiZn ferrite nanoparticles with the increase of its concentration. The non magnetic property of zinc, decreased the saturation magnetization and coercivity values of NiZn ferrite nanoparticles. The dielectric constant and dielectric loss factor values also increased with the increase of zinc concentration due to the increase of probability of electrons reaching the grain boundary. Low value of particle size obtained at higher zinc concentration in the present work indicated that NiZn ferrite nano particles in lower nanometer scale could be obtained at higher zinc concentration.

Teen People Magazine The Teen People, September edition, is a magazine designed to appeal to young female readers. Its content features well known celebrities, use of bright and flashy colors, and an organized layout that attracts an upbeat, young readership interested in high-quality appearance and style. Although the magazine’s main focus may appear to insure a great fashion sense, it also concentrates on a philosophical orientation by covering a more diverse readership that includes all colors, sizes, and shapes of females. Teen People also expands its audience by recognizing both visual and text oriented audiences. To appeal to the more visual oriented audience, the magazine uses exotic photography in the advertisements for Self Esteem, Secret Deodorant, and Ralph Lauren. For the more text oriented audience, the magazine includes celebrity profiles on Ruben Studdard as well as both Nick Lachey and Jessica Simpson. Whether the audience is visual or text oriented, Teen People’s main objec tive is to create an animated and enjoyable magazine for young female readers. The advertisement for the clothing line Self Esteem uses an imaginative idea of a human butterfly to catch the eye of its visual oriented viewers (117). The advertisement pictures a young Mediterranean female with butterfly wings attached to her back. She is dressed in casual attire with green cargo pants and a simple khaki colored shirt. The unusual depiction and choice in clothing may insinuate that an athletic female reader can effectively express herself by dressing comfortably in Self Esteem clothing wear. The smile and happy indication illustrates that freedom of originality leads to eternal happiness. Self Esteem places the young female in the midst of... ...emales tend to desire. Self Esteem uses a deeper level of thinking to portray beauty. Secret Deodorant tends to advertise angelic beauty, whereas companies such as Ralph Lauren advertise natural beauty. Although both articles use big celebrities to attract their readers, they tend to differ in who is attracted and why they are attracted to the article. Whatever the approach may be, Teen People Magazine accurately appeals to all types of people who desire a good style sense, information on their favorite celebrities, and overall beauty.

History of HTML Essay

HTML or HyperText Markup Language is the predominant and most currently most popular language for creating web pages. It is a well-designed language to describe the structure of text-based information in a document by using certain tags referred to as HTML tags and using certain text links, heads, paragraphs, tables, lists and headings. While HTML is written in the form of tags, surrounded by angle brackets. HTML can also describe, to some degree, the appearance and semantics of a document, and can include embedded forms, and other scripting language codes, which can affect the behavior of Web browsers and other HTML processors. It is assumed that what made this language a very popular web development language is its English-like characteristic which makes it relatively easy to comprehend, and memorize the tags as compared to most other languages. It was in the late 1980’s, when the physicist Tim Berners-Lee, who was an independent contractor at CERN, proposed and prototyped ENQUIRE, a system for CERN researchers to use and share documents. In 1989, Berners-Lee and CERN Robert Cailliau, a data systems engineer from CERN, each submitted separate proposals for an Internet-based hypertext system providing similar functionality. The following year, they collaborated on a joint proposal, the Worldwide Web (W3) project; this proposal was accepted by CERN and as of now, and the project continued to grow from the day that it was developed, and continuous to grow up until present. In the advent of the interne and in the continuous increase in its popularity, came parallel the advent of the web-development language HTML. Although it has already been an accepted and established concept in the field of academics as early as the 1940s. It was with the advent of he personal computer that hypertext came into popularity. Bill Atkinson came up with the astounding idea in the late 1980s. It was then the he and his team developed Hypercard, an application for the Macintosh Operating System. Hypercard allows users to construct a series of on-screen `filing cards’ that would be able to contain text and graphics. Users can also navigate through these filing cards by pressing on-screen buttons, which were designed for simple and plain navigation. Hypercard easily became popular and was integrated on many other applications. Toolbox, for Personal Computers was developed and popularized in the 1990s for hypertext training courses. These courses came up with a more advanced navigation system wherein viewers or users were able to view pages with buttons which can help them navigate forward or backward or jump to a topic. Hypercard and its co-programs easily became popularized, however they were still held back by certain limitations. The major limitation was that hypertext jumps were only allowed to be made to files on the same computer. Hypertext umps to computers on other countries or on the other side of the world were still not possible. Hypertext communication was still on the local scale and not available in the global scale. It the increasing demands for global scale hypertext communication that the HTML came into advent. HTML has had a development-span of roughly seven years. During that time, it has evolved from a simple language with a small number of tags to a complex system of mark-up tags, enabling authors to create visually stunning web pages complete with sound and animation. Basically, the language developed from HTML+, HTML 2, HTML 3. 2, HTML 4. And finally HTML 5, which was released in 2008. A document called â€Å"HTML Tags†, was the first publicly available description of the HTML. This was known to public by Tim Berners-Lee in 1991. It describes 22 elements comprising the initial, relatively simple design of HTML, thirteen of these elements still exist up to HTML 4. At that time, Berners-Lee considered HTML to be an application of Standard Generalized Markup Language or SGML. However, it was not formally announced until the mid-1993 publication, by the IETF, of the first proposal for an HTML specification. Berners-Lee and Dan Connolly’s made an internet draft, â€Å"Hypertext Markup Language (HTML)†. This included an SGML document type definition to define the grammar. The HTML and HTML+ drafts expires in 1994, and that was when IETF created an HTML Working Group, which in 1995 completed â€Å"HTML 2. 0†, the first HTML specification intended to be treated as a standard against which future implementations should be based. HTML 2. 0 included ideas from the HTML and HTML+ drafts. HTML 2. 0 became the standard for website design until the year 1997. By then, more people were using HTML, and while the previous standards offered some decent abilities, people thirsted for more abilities and tags as to be able to better enhance the appearance of their websites. At this time, a HTML working group, led by Dave Raggett introduced HTML 3. 0. It included many new and improved abilities for HTML, and promised far more powerful opportunities to HTML users. HTML 4. 0 was recommended by W3C in 1997 and became the official standard in April 1998. Browser support was undertaken surprisingly earnestly by Microsoft in their Internet Explorer browser HTML 4. 0 was a large evolution of the HTML standards, and the last version of the classic HTML. At present, the newest version of the HTML is HTML 5. 0. It was published as a working draft by W3C last January 22, 2008, and includes major revisions in the core language of the World Wide Web, HTML. In this version, new features, elements and functionalities had been introduced to aid web developers to further improve the appearance and back-end structure of websites.
