What is glass-transition temperature? Give a material example. How many types of polymer structures do you know? Briefly explain each type of polymer structures. b) What is creep and what is stress relaxation? c) What are the two structure components in reinforced plastics and what are the functions of each of them? What are the advantages and disadvantages of reinforced plastics comparing with the regular plastics? Solution a) The glass–liquid transition or glass transition for short is the reversible transition in amorphous materials (or in amorphous regions within semicrystalline materials) from a hard and relatively brittle \"glassy\" state into a molten or rubber-like state, as the temperature is increased. An amorphous solid that exhibits a glass transition is called a glass. The glass-transition temperatureTg of a material characterizes the range of temperatures over which this glass transition occurs. It is always lower than the melting temperature, Tm, of the crystalline state of the material, if one exists. Examples Rubber elastomers like polyisoprene and polyisobutylene are used above their Tg\'s, that is, in the rubbery state, where they are soft and flexible. Typical polymer structures are b) creep is the tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses. It can occur as a result of long-term exposure to high levels of stress that are still below the yield strength of the material. Creep is more severe in materials that are subjected to heatfor long periods, and generally increases as they near their melting point. Stress relaxation is defined as a gradual decrease in stress with time under a constant deformation or strain. c) Fibre-reinforced plastic is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass, carbon,aramid, or basalt. Rarely, other fibres such as paper or wood or asbestos have been used. The polymer is usually an epoxy, vinylester or polyester thermosetting plastic, andphenol formaldehyde resins are still in use. Advantages Disadvantages.

What are some contributions to the development of industrialization made by the steam engine. In other words what role did the steam engine play in the development of the industrial revolution What are some contributions to the development of industrialization made by the steam engine. In other words what role did the steam engine play in the development of the industrial revolution What are some contributions to the development of industrialization made by the steam engine. In other words what role did the steam engine play in the development of the industrial revolution Solution Answer: The steam engine was one of the most important technologies of the Industrial Revolution, although steam did not replace water power in importance in Britain until after the Industrial Revolution. From Englishman Thomas Newcomen\'s atmospheric engine, of 1712, through major developments by Scottish inventor and mechanical engineer James Watt, the steam engine began to be used in many industrial settings, not just in mining, where the first engines had been used to pump water from deep workings. Early mills had run successfully with water power, but by using a steam engine a factory could be located anywhere, not just close to water. Water power varied with the seasons and was not available at times due to freezing, floods and dry spells The technological advances of the Industrial Revolution happened more quickly because firms often shared information, which they then could use to create new techniques or products. From mines to mills, steam engines found many uses in a variety of industries. The introduction of steam engines improved productivity and technology, and allowed the creation of smaller and better engines. The development of the stationary steam engine was an essential early element of the Industrial Revolution, however it should be remembered that for most of the period of the Industrial Revolution the majority of industries still relied on wind and water power as well as horse and man-power for driving small machines. Transportation was one of those important beneficiaries. By the early 1800s, high-pressure steam engines had become compact enough to move beyond the factory, prompting the first steam-powered locomotive to hit the rails in Britain in 1804. For the first time in history, goods were transported over land by something other than the muscle of man or animal. The railroad rapidly spread and sped transportation. This created new jobs, forcing people to move into cities. Cities like London, for example, the steam engine and locomotive propelled countless other industries such as driving bellows and rollers, spinning machines, and weaving machines. And, for the first time in history, people had the ability to quickly and cheaply move to big cities to find work, as opposed to working on a farm. Subsequently, it had a major impact on businesses, as it boosted production of natural resources, which were vital to society, and created numerou.

The “creative revolution” that handed more authority to agency art directors and copywriters in the 1960s led to key shifts in the appearance and message of mainstream advertising. Describe these changes and how they continue to influence advertising today. Solution The key shift in terms of appearance and message of mainstream advertising was that the commercials started using irony and irreverence to reach out to the young customers. The situation was that the young customers were indifferent to advertisements by companies at that time. Advertisements were designed, both in terms of its message and appearance, to connect with the youth. Secondly, the creative revolution also saw social messages and issues being used in commercials and advertisements. These changes continue to influence advertising today. Advertisements, be it print or any other media, increasingly are targeting the youths. Marketers are not afraid of using self deprecating humor or using social messages in today\'s advertisements and commercials..

The project will study the coordination of multiple threads using semaphores. The design should consist of two things: (1) a list of every semaphore, its purpose, and its initial value, and (2) pseudocode for each function. Code Your code should be nicely formatted with plenty of comments. The code should be easy to read, properly indented, employ good naming standards, good structure, and should correctly implement the design. Your code should match your pseudocode. Project Language/Platform This project must target a Unix platform and execute properly on our cs1 or csgrads1 Linux server. The project must be written in Java. Elevator Simulation In this project threads are used to simulate people using an elevator to reach their floor. The threads to be used are as follows: Person: 1) 49 people are in line at the elevator at the beginning of the simulation (1 thread per person). 2) Each person begins at floor 1. 3) Each person randomly picks a floor from 2 to 10. 4) A person will wait for an elevator to arrive at floor 1. 5) A person will board the elevator only if there is room. 6) Once at the destination floor, the person exits the elevator. Elevator: 1) There is 1 elevator (1 thread for the elevator). 2) The elevator can only hold 7 people. 3) The elevator begins on floor 1. 4) The elevator leaves after the 7th person enters. Main 1) Creates all threads and joins all person threads. 2) When last person reaches their floor, the simulation ends. Other rules: 1) Each activity of each thread should be printed with identification (e.g., person 1). 2) A thread may not use sleeping as a means of coordinating with other threads. 3) Busy waiting (polling) is not allowed. 4) Mutual exclusion should be kept to a minimum to allow the most concurrency. 5) The semaphore value may not obtained and used as a basis for program logic. 6) All activities of a thread should only be output by that thread. Sample output: Your project’s output should match the wording of the sample output: Elevator door opens at floor 1 Person 0 enters elevator to go to floor 5 Person 1 enters elevator to go to floor 2 Person 2 enters elevator to go to floor 8 Person 3 enters elevator to go to floor 4 Person 4 enters elevator to go to floor 6 Person 5 enters elevator to go to floor 7 Person 6 enters elevator to go to floor 2 Elevator door closes Elevator door opens at floor 2 Person 1 leaves elevator Person 6 leaves elevator Elevator door closes Elevator door opens at floor 4 Person 3 leaves elevator Elevator door closes Elevator door opens at floor 5 Person 0 leaves elevator Elevator door closes Elevator door opens at floor 6 Person 4 leaves elevator Elevator door closes Elevator door opens at floor 7 Person 5 leaves elevator Elevator door closes Elevator door opens at floor 8 Person 2 leaves elevator Elevator door closes Elevator door opens at floor 1 … Simulation done Solution public class Person implements Runnable{ //possible actions public static final int WAITING = 1; publ.

The local public health agency has received reports of an outbreak of Salmonella gastroenteritis among attendees at a city-sponsored chili cook-off. What techniques from recombinant DNA technology would the agency likely use to investigate this outbreak? Describe the expected results from these techniques. Solution Please note that the investigation of the outbreak would require molecular biology techniques, not recombinant DNA technology! There would be two steps in the investigation: 1. Establishing that the gastroenteritis is due to Salmonella: Molecular identification techniques such as FISH (Fluorescence in situ hybridization) or Enterobacterial Repetitive Intergenic Consensus (ERIC)-PCR can be used. 2. Establishing that the Salmonella among the attendees is of the same strain: Molecular phylogenetic techniques such as 16S rRNA sequencing or MLST (Multilocus Sequence Typing) can be used..

how are musical sounds produced? Explain your reasoning. Solution Almost all musical programs are produced basically in two stages: (1) Sound from each individual intrument is recorded in an acoustically inert studio on a single track of a multitrack tape recorder (2) Signals from each track are manipulated by the sound engineer by adding special audio effects and then combined in a mix-down system to generate the final stereo recording on a two- track tape recorder The special audio effects are either generated using time-domain operations or frequency-domain operations. Commonly used time-domain operations are echo generation,reverberation,flanging,chorus generation, and phasing. Commonly used frequency-domain operations are filters and equalizers.

5. What is the role of the SRY gene in determining sex? Solution ANS: SRY (Sex Determining Region of Y chromosome) Gene: In the early stage of embryonic development, immature gonads of male and female are indistinguishable. Male: During the 7th week of embryonic development, SRY gene present on the Y chromosome is activated. So due to these later gonads develops into testes. Female: In females SRY gene is absent, so gonads later develops into ovaries by default. The Y chromosome in humans contains SRY gene. This gene can capable to produce TDF (testis determining factor). On Y chromosome approximately 150 genes are present. SRY region only determines male characteristics. In mice spontaneous deletion or insertion of SRY gene can results, in mice with XX have testes and XY mice present with ovaries..

Explain why the cultural differences argument is not sound? Solution Because of Cultural Relativism. ================================================= To numerous scholars, this observation. \"Different societies have distinctive good codes, has appeared to be the way to comprehension profound quality. The possibility of generally accepted fact in morals, they say, is a myth. The traditions of various social orders are all that exist. These traditions can\'t be said to be \"right\" or \"inaccurate,\" for that infers we have an autonomous standard of good and bad by which they might be judged. Yet, there is no such free standard; each standard is culture-bound. The colossal spearheading humanist William Graham Sumner, writing in 1906, put the point this way: The \"right\" way is the way which the precursors utilized and which has been passed on. The custom is its own warrant. It is not held subject to check by involvement. The idea of right is in the folkways. It is not outside of them, of autonomous root, and conveyed to test them. In the folkways, whatever is, is correct. This is on the grounds that they are conventional, and accordingly contain in themselves the specialist of the tribal apparitions. When we go to the folkways we are toward the finish of our investigation. This line of thought has most likely induced a bigger number of individuals to be suspicious about morals than some other single thing. Social Relativism, as it has been called, challenges our conventional faith in the objectivity and all inclusiveness of good truth. It says, as a result, that there is not such thing as generally accepted fact in morals; there are just the different social codes, and nothing more. Besides, our own code has no uncommon status; it is only one among numerous..
