Nt1310 Unit 2 Lab Report

Lab 1 helps create a better understand of the changes in crystal structures when the annealing and quenching process is applied to 1020 and 1080 steel. The numbered steel refers to the ASTM grain-size number. Formula 1 is used to solve for the grain size. n=2^(G-1) Equation (1) at 100x magnification Crystal structures change shapes which changes the strength of the material and its properties. The metal might become soft, brittle, hard, or ductile.

Chapter 7 is to discuss the actual implementation and issues found during the experiment. The number of issues that were found during the project will be discussed in this chapter. Types of issues that will be discussed, are component issues, integration issues and construction issues. A cost summary of the components that were bought, will be shown in this chapter. 7.2 COMPONENT AND INTEGRATION

2.4 Band Division and Energy Computation: The power spectrum of the signal is multiplied by magnitude response of set of 33 triangular band pass filters and in the range 300Hz-2000Hz. Sub-bands are formed by using the logarithmic spacing. The positions of these filters are equally spaced along the Mel frequency, which is related to the common linear frequency f by following formula: Mel (f) = 1125* ln (1+f/700) (3) Mel frequency is proportional to the logarithm of linear frequency and which is close to the human perceptual system. 2.5 Sub Fingerprint Generation:

Using the data provided in each one of these tests it can be assumed that one has done the steps to be able to determine the magnitude and orientation of the charges of the tape in each test, thus, allowing them to apply the same principle to any object they so desired. Their results would line up with the following; that if the two pieces of tape are torn from the same 40 centimeter strip then the tops of both pieces of tape would be positive and the bottoms of both pieces of tape would be negative and that if they would double the tape the attraction or repulsion in general would lower due to the increased density. Their data would also show that two pieces of tape ripped from each other would result in one piece being entirely positive and the other being entirely negative, they would also be able to state that the orientation of how the tape is paired up doesn’t matter.

4.) I noticed that there is a relationship between the ionic radius and the atomic number of the representative elements in Group 1A. The higher the atomic number, the bigger the ionic radius is. So, while hydrogen has an atomic number of 1 and Francium has an atomic number of 87, it is safe to assume that FR has a higher ionic radius. This is true; the ionic radius for Hydrogen is 0.012, and for Francium, it is 0.194.

Medical biller is a position that will require you to take in medical claims and code them and bill out medical claims to insurance companies, Medicare and Medicaid on a daily basis. You will have to reconcile Explanation of Benefits (EOB) weekly. Verify if insurance companies require that patients get PA for certain procedure and products. Five requirements for Medical Biller position 1. How to bill claims 2.

• Ensure service members’ records were filed properly and maintained in the individual record. • Procure service member records in-order to be mailed out to other claim offices, having major effects on individuals. • Ensure all regulatory requirements pertaining to individual privacy were adhered to. • Research and obtain all necessary paperwork and relevant information regarding cases and issues pertaining to individual records. • Identify records, inconsistencies and initiated actions to correct the problems.

What is polysomnography? Describe the three techniques used to produce a polysomnography This is a test used to study and records the brain waves, oxygen level in the blood, heart rate and breathing also the eye and leg movement during sleep. Electroencephalogram: used to measured and record brain wave activity. Electromyogram: used to record muscle activity such as face twitches, teeth grinding, and leg movement.

During this stage, respiration becomes shallow and muscle relaxation occurs. The stage is associated with the feeling of falling , and accompanied by a reflex response such as jerking of arms and legs. As the person progresses into stage two, the theta waves become intermingled with sleep spindles and complex waves. Sleep spindles which can be measured by EEG signals, arguably define the beginning of actual sleep since the person is oblivious to most external stimuli. This stage last’s from 10 to 20 minutes.

My experiment is about going to the gym 6 times in one week to find the accurate result for the experiment. For the first 3 days I will not have enough sleeping hour (less than 8 hours), and I go to the gym to look at my performance is high or low in the gym. Letter, the next 3 days I will

Shift working According to the European Union (EU) Survey on Working Conditions , carried out in 2000 in the 15 EU countries, only 24% of the working population (27% of employed and 8% of self-employed workers) are now engaged in the so-called ‘normal’ or ‘standard’ day work, that is between 7.30-8.00 and 17.00 – 18.00 Monday to Friday and 18.8% of workers are involved in shift work that includes night work (Costa 2003). This means that the majority of the working population is engaged in shift work, night work, part time work, varying working hours, weekend work. These trends are likely to continue as economic demands, market globalization and societal changes push us into a 24 hour society. Most studies and reports that refer to shift

Participants were also asked to keep a sleep diary in order to record possible explanations for sleep abnormalities. One experimental day consisted of playing a computer game for an hour. Another experimental day consisted of watching a movie of the participants’ choice between the hours of 6 and 7 in the evening. The other experimental day consisted of the sleep
