1.1 What is a composite material? Composite materials are materials in which a homogenous matrix is reinforced by a stronger and stiffer constituent that is usually fibrous but may have a particulate or other shape (web.mit.edu). They are produced when two or more materials or phases are used together to give a combination of properties that cannot be attained otherwise. For example steel reinforced concrete, plywood and fibre glass. 1.2 What is a Ceramic Matrix Composite (CMC)? CMCs are a…

Name: Institution: Course: Instructor: Date of Submission: Pendulum and spring Abstract In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations. Introduction Any system that exhibits back and…

Lactate dehydrogenase was assayed according to the method of King (1965) [21]. Reagents required: 1. 0.1 M glycine buffer: 7.5 g of glycine and 5.85 mg of sodium chloride were dissolved in one litre of distilled water. 2. Buffered substrate: 2.76 g of lithium lactate was dissolved in 125 ml of glycine buffer containing 75 ml of 0.1 N sodium hydroxide solution. This was prepared just before use. 3. 0.4 N NaOH. 4. 5.0 mg of NAD+ was dissolved in 1.0 ml of distilled water just before use. 5.…

In two books, Open City and Portrait with Keys, the narrative voices differ greatly, yet both reflect similar realities about the existence of privileged individuals within cities stricken by extreme poverty, crime and sexual assault; both works demonstrate the desensitizing nature of cities on their inhabitants, and convey that the city itself allows violence and loneliness to exist as commonplace realities in an environment that simultaneously suppresses the visibility of individual action…

quantitatively determined with suitable precision and accuracy. Quantitation Limit (LOD) may be expressed as LOQ = 10 S Where = the standard deviation of the response S = the slope of the calibration curve (of the analyte) f) Ruggedness Method ruggedness is defined as the reproducibility of results when the method is performed under actual use includes different analysts, laboratories, columns, instruments, sources of…

Introduction: In the northwestern areas of Washington sunshine is a rather rare occurrence. Approximately nine months out of the year the sky is full of gigantic grey clouds filled with rainwater. During those nine months there's usually a relatively constant amount rainfall covering Bothell. Many citizens who have been experiencing the phenomena of rain for countless years are unaware that there's a difference in rainwater from previous decades. The pH of rainwater has been slowly decreasing…

Iron (Fe3+) is a metal that rusts when it is exposed to air, it is also an important nutrient in the human body 1. The form of iron found in foods which is (Fe3+) is different to the type of iron that is absorbed by the body Fe2+ 2. Fe3+ is an iron mixed with oxygen, this is an insoluble form of iron 3. However, the body converts this iron into the form of ferrous which is soluble (Fe2+) 3. Iron is a vital component of not only the human body but also other living things 3. This is due to the…

Calibration is part of why continuous feedback is required for increased productivity and successful partnerships in a firm, because as stated by Lee (2007) “The best way to find solutions to common problems is to collaborate and this collaboration requires…

elemental form. This is not the most accurate way to collect iron from a sample, but it was mostly successful. The amount of iron collected was poor because of the big percentage of error in this experiment. Using the standards provided in class, a calibration curve could be created to get a general idea of how much iron was in the unknown…

Vibration Experiment Preface The mechanical vibration (Mechanical Vibration) is Oscillations (Periodic Motion) or random (Random Motion) of the mass of the mechanical system versus a balanced static system, the mechanical vibrations caused by mechanical systems (Structure or equipment), which is in a state of static equilibrium is disturbed by an external force. Resulting in the exchange of kinetic energy and potential energy between the mass and spring of the system. An example of interference…
