...Abstract In this lab we tested the contamination of water using oil, vinegar, and soap. Using plain tap water I added various amounts of contaminants to the water and noted the change. Introduction The introduction should describe the background of water quality and related issues using cited examples. You should include scholarly sources in this section to help explain why water quality research is important to society. When writing this section, make sure to cite all resources in APA format. The introduction should also contain the objective for your study. This objective is the reason why the experiment is being done. Your final report should provide an objective that describes why we want to know the answer to the questions we are asking. Finally, the introduction should end with your hypotheses. This section should include a hypothesis for each one of the three experiments. These hypotheses should be the same ones posed before you began your experiments. You may reword them following feedback from your instructor to illustrate a proper hypothesis, however, you should not adjust them to reflect the “right” answer. You do not lose points for an inaccurate hypothesis; scientists often revise their hypotheses based on scientific evidence following an experiment. Materials and Methods The materials and methods section should provide a brief description of the specialized materials used in your experiment and how they were used. This section needs...

...Final Lab Report James Dillon SCI 207: Dependence of Man on the Environment Instructor: Jessica Bostock February 20, 2016 Final Lab Report Abstract The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on water treatment and a filtration system using cheesecloth, sand, activated charcoal, alum, and gravel was created. The contaminated water sample was created by mixing soil and water together. After the contaminated water was put through the filtration system and a few drops of bleach were added you could see that much of the sediment was filtered out, but an overwhelming bleach smell remained. The third experiment was to determine drinking water quality. Samples of Dasani and Fiji bottled water were compared to my local tap water. Test strips were used to determine each samples ammonia, chloride, alkalinity, chlorine, hardness, phosphate, and iron levels. The results were that the Dasani water was cleaner overall and that the Fiji water and...

...Experiment #9: Infrared Spectrometry 1: Sampling Methods and Qualitative Analysis Corrales, Monique V. Go, Carleen Jade M. Ms. Stephanie Chan February 20, 2014 March 13, 2014 I. Abstract This experiment aims to introduce the different infrared spectrometry sampling techniques and also to identify an unknown solution using qualitative analysis of the solution’s infrared spectra. There are a total of three (3) sample mounting techniques introduced in this experiment namely, the pellet, mull, and film techniques. There are two kinds of samples that are tested—two liquids and one solid. The solid undergoes all three sampling techniques while the liquids undergo just the film technique. Results show that the sampling techniques are effective and accurate in the analysis of compounds. II. Keywords 1. Spectrometry- the use of the absorption, emission, or scattering of electromagnetic radiation by matter to qualitatively or quantitatively study the matter or to study physical processes 2. Mull-a mixture of a solid substance and oil _______________________________________¬¬¬-______________________________________________ III.

...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...

They were previously known as AT&T Bell Laboratories and Bell Telephone Laboratories is now the research and development subsidiary of the French-owned Alcatel-Lucent. Over the past eight decades, Bell Labs R&D gave birth to new technologies and seminal scientific discoveries. (Alcatel Lucent, para 1) Elisha Grey and Enos N. Barton formed Western Electric Company in 1869. Both of them started a small manufacturing firm based in Cleveland, Ohio which was to become the largest electrical manufacturing company in America. In 1881, Alexander Graham Bell, an extraordinary leader of American Telephone & Telegraph (AT&T), purchased a controlling interest in Western Electric and made it the exclusive developer and manufacturer of all equipments for the Bell telephone companies. Now, the Bell system has provided much telephone services and support to America and Canada in the 1877 to 1984. It was then led by AT&T. In 1898, Compagnie Générale d'Electricité (CGE) was born, founded by a French engineer named Pierre Azaria. It was involved in business with several industries in Germany. Mainly it dabbled in electricity, transportation, electronics and telecommunications. CGE then rose up the ranks and became a leader in digital communications and would be known as well to produce train à grande vitesse – high speed trains in France. In...

...Costs both internal and external. Appraisal costs relate to the costs of ensuring quality and for uncovering defects. These costs are related to inspections, testing, test equipment, labs, quality audits, and field testing. Prevention costs include both planning and administrative systems, interaction with vendors, training, quality control procedures, and emphasis on design. Failure costs are broken into two subcategories, Internal and External failure. Internal failures include defective material, incorrect machine settings, carelessness, and mishandling of materials. External failure is associated with defective products or poor service provided to the customer. Appraisal costs and quality considerations for Widget 3.0 production Analysis indicates 45% of the final cost of the product is attributable to inspection, testing, and quality audits.

...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.
