...Electronics rely heavily on electronic switching and amplification to generate and capture the various signals which allow them to operate. A controllable valve that allows a small signal to control a much larger signal does this, and could be related to a controllable valve used in the control of water flow. This was once done by a device known as vacuum tube but was later brought down to a much lower production scale for a variety of industrial, economical and business related reasons. Bell Laboratories, the research arm of telecommunications company American Telephone and Telegraph’s (AT&T) director Mervin Kelly put together the first team of researchers and scientists placed on the task of research and development of a solid state-semiconductor later called a transistor that would supersede vacuum tubes and provide numerous advantages. The success of this development would prove to change the computing, electronics and telecommunications systems altogether. Up until the invention of the transistor a vacuum tube was used in the control, amplification and generation of electrical signals. Vacuum tubes are tubes usually made from glass and designed in an airtight manner as to keep the flow of “cathode rays” from external disturbance as they pass from each terminal and laid the foundation for numerous technical innovations, such as the light bulb discovered by Thomas Edison (fig. 1). Joseph John Thomson further made a vacuum tube and placed a third terminal to attain a grasp...

...The effects on heart rate on a Daphnia Magna with varied substances William Piper WCCC/Spring 2015 Semester A&P 2 Dr. Sisak Introduction: The purpose of the experiment conducted was to test the effects of varied substances on the heart rate of a Daphnia Magna. A Daphnia Magna is a freshwater flea native to North America (Wikipedia, 2015). The substances used on the Daphnia were aspirin, nasal spray, Alka-Seltzer, coffee, and tea. Aspirin is a common pain reliever and fever reducer (Rx List, 2015). Pain increases heart rate; therefore, a pain reliever would inherently reduce the heart rate of an organism (Storella, 1998). Nasal spray works by constricting blood vessels in the nose to help reduce swelling and inflammation to...

...Name: Yolanda Sanchez Lab Activity 11 – Aquatic Biodiversity (Macroinvertebrates) NSCI 102 In this activity, you will learn about how samples of macroinvertebrates found on stream bottoms can be analyzed to determine water quality. Macroinvertebrates are organisms with no backbone that are visible without using a microscope. Crayfish, aquatic snails, and the larvae of aquatic insects are examples of stream-bottom macroinvertebrates. Macroinvertebrates are an important link in the aquatic food chain. They feed upon algae and leaves that fall into the stream and are eaten by larger consumers, such as fish. Macroinvertebrates are useful for studying water quality because some of them cannot survive in polluted waters, while others thrive. Since stream-bottom macroinvertebrates do not generally move very far within a stream, they are excellent indicators of long-term pollution trends. Levels of pollution may vary over time, so a one-time chemical analysis of the water may not provide an accurate picture. However, if pollutants are common in a stream, the macroinvertebrates found there will primarily be the ones that are tolerant of poor water quality. In addition, macroinvertebrates are relatively easy to collect, so analyzing this community can be used to get an initial indication of water quality to see if additional chemical tests are necessary. Materials needed for this lab: - Handouts: Stream Sample A, Stream Sample B, Macroinvertebrate Key ...

Name: Eric Ohman _ Date: 02/26/2016 Name: David Farrier _______Date: 02/26/2016 Name: Lucas Fischer ______ Date: 02/26/2016 Name: David Hernandez Date: 02/26/2016 ABSTRACT Several experiments were conducted on various drilling fluid samples, chiefly relating to the effects of viscosifiers (Bentonite), weighting agents (Barite, and salt on the filtration properties of these muds. Clear knowledge of the filtration properties of drilling fluids is of great importance to the drilling engineer as excessive filtration can cause both damage to the formation both from fine particles and from water infiltration. There are many negative effects of excessive filtration, including the loss of expensive drilling fluid, damage to the formation, and stuck pipe caused by large amounts of filter cake. In this experiment, using mud cakes were formed from mud samples of varying composition using a filter press. These results were then analyzed in fluid loss vs. square root of time...

...no nation is currently capable to compete with the demand for medical -care and its supply. Scientists hence are under growing pressure to extend fresh technologies to raise consumers prompt access to medical -care A most noteworthy and ground-breaking progress in the field of medicine has been development of point-of-care testing. Consistent with (15) POCT is described as patient samples examination at or close to the patient carrying the supposition that test outcomes will be obtainable instantaneously or within an extremely short timeframe thereby helping caregivers in the instantaneous diagnosis and medical intervention(26) .Point-of-care testing is performed away from the traditional central laboratory setting , and has created easier self-management as individuals can examine themselves and react to the outcomes as counseled by their doctors. POC testing machinery is vital to the accomplishment of life-saving and disaster management undertakings as assessments can be conducted in intensive care units or in an ambulance where judgments are time-susceptible. Reliability of POCT and central lab testing As mentioned, POCT is regularly executed outside of the clinical laboratory and carried out by non-laboratory staff. Therefore, it is obvious that the consistency of POCT relies wholly on the practical performance of POCT...

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...

...Blogging is popular among the people in today’s society, especially amongst teenagers. In fact, the number of blogs is exploding, with about 14 million existing blogs. On average, the number of blogs is doubling every five months. There are many advantages of blogging. Firstly, people can use as an online dairy, using it to share the day’s happening in her life with other visitors on the net. Furthermore, if the blogger (author of the blog) has met up with certain incidents in her life, he can share it on the blog and others can console or praise him, by giving comments or leaving a message in the blog’s tag board, depending on the incident. Blogging can also be a good way to relieve stress as some way wants to use their blog to vent out their frustration or pour out their woes when stress becomes too much for them. Some bloggers even use their blogs to flaunt their literati skills by posting poems about themselves or things around them. Secondly, bloggers can also use their blogs to inform others on a certain topic which happens to be his niche, thus allowing others who are interested in the topic to learn some tricks from the blog, they are also post questions to the blogger if they meet up with problems. Even Mr. Donald Trump is doing so, he launched the Trump Blog last month to share his insights into and answer questions about corporation ethics, personal success and business dilemmas. Other organizations are also using blogs to make announcements to...
