Pharmaceutical Industry - Essay Example This guarantees the evaluation of all pharmaceutical products in America where the Food and Drug Administration regards them as both safe and effective before the product can be widely distributed and sold (Laws.com, 2013). Failure to understand the medication or conduct thorough clinical trials of the product by a pharmaceutical company in this industry attracts civil lawsuits (Laws.com, 2013). The most popular pharmaceutical companies in this industry include GlaxoSmithKline, Pfizer, and AstraZeneca (Association of the British Pharmaceutical Industry, 2011) where pharmaceutical companies from the United States dominate the industry (WHO, 2014).Pfizer Inc. is one of the largest pharmaceutical companies in the world in terms of revenues. Headquartered in New York City, Pfizer Inc. is an American multinational pharmaceutical corporation and the world's largest research-based pharmaceutical company (Pfizer Inc, 2013). The company does its research in Connecticut, United States. It reco rded US$ 58.98 billion revenues in 2012 (Pfizer Inc, 2013). Johnson & Johnson is another American multinational pharmaceutical company that embraces research and science with an aim of bringing innovative ideas, products and services to advance the health and well-being of people (Johnson & Johnson Services, Inc, 2014). Headquartered in New Brunswick, New Jersey USA, Johnson & Johnson is the world’s largest and most diverse medical devices and diagnostics company (Johnson & Johnson Services, Inc, 2014).

Electronic stethoscope - Lab Report Example Components functions LM386 Low Voltage Audio Power Amplifier is an auditory amplifier designed for exploitation in low electrical energy consumer purpose which provides both current gain and voltage for signals. Hence, power amp with variable gain is considered with the assistance of op-amp LM386. It acts as a low-noise microphone pre-amp. Its gain is approximately 3.9 because the high productivity impedance of the exhaust of the FET within the electrets microphone makes efficient input resistor to be approximately 12.2K. MPF102 Transistors’ purpose is to manage current by an electric field; voltage produces only a small raise in drain current. 1K Ohm 1/4-Watt Carbon Film Resistor provides accurate amounts of resistance in electric circuits. Resistors are marked both in regards to their resistance (1K ohms) and their capability to dissipate high temperature energy (1/4-watts). 1M Ohm 1/4-Watt Carbon Film Resistor refers to 1M ohm resistance and a quarter heat dissipation. 10 o hm 1/4W 5% Carbon Film Resistor and 4.7K Ohm 1/4-Watt Carbon Film Resistor likewise give the corresponding resistance and dissipation. (x2) 0.047 µF 50V 10% PC-Mount Capacitor separates the microphone route from the LM324 quadruple functioning amplifier. This way, the LM386 can operate at the full 12 V without hindering the voltage of the microphone circuit. 0.1 µF 50V Hi-Q Ceramic Disc Capacitor also operates on the same basis of the above capacitors, however, in regards to its ratings. Project Enclosure (3X2X1") has Project Box, Aluminum Lid and Plastic lid. This enclosure comprises four standoffs in the base corners to sustain a PC board. Standoffs are 1/4" far above the ground with holes that allow sharp 4 screws. Slots are available on all four sides of the apparatus to allow a PC board to be fixed horizontally or vertically alongside the length or breadth of the enclosure. Enclosure has aluminum and plastic lids. Multipurpose Pc Board with 417 Holes is a grid-style PC plan k as the starting point for electronics task. It includes 417 pre-drilled punctures. The board measurements are 1.875 inches by 2.875 inches. JVC GumyEarBuds represent an improvement in comfort, fitting the ear with an exceptional curved housing. The big 0.53" (13.5mm) neodymium components in these blue earbuds convey a superior listening practice. 10K-Ohm Linear-Taper Potentiometer: B10K 17mm With Dust fasten has modifiable top with power of 1/2W, Resistance: 10K OHM OHMS, Knurled Shaft, Shaft Diameter: 6mm, Shaft Length: 10mm, Suits Most Standard knobs, Mounting Hole: 7.5mm and Base Diameter: 16mm. Hexagonal control knob 1-1/4" length by 5/8; Sold in packages of two. 1/8" Mono Panel-Mount Audio Jack; NOTE: This component does come with the anchoring nut to assist in fixing. Specifications:  type: mono, with insert switch, solder connections and in housing. This 6-foot insulated cable features a 1/8" handset plug on each terminals. Shielded to safeguard signal potency and guard a gainst buzz. Also, a 6-foot lead has a 1/8" handset plug on each terminal also insulated to preserve signal power and guard against hum.
