...The purpose of this lab was to investigate an inherited disease by conducting a series of experiments. We conducted a total of four experiments. By looking at DNA for mutations, counting cells in mitosis to determine the rate of cell division, using pedigrees to hypothesize patterns of inheritance and using a larger worldwide data set from multiple families with the disease to test the predicted pattern of inheritance all contributes to the purpose of the lab, which mentioned before was to investigate and analyze an inheritable disease. In Lab 3.1 we attempted to identify mutations in a gene associated with a newly discovered disease. Mutations are heritable changes in a gene’s nucleotide sequence. Mutations may change an individual’s phenotype or may have no affect at all. The central dogma of biology played a role in this part of the experiment. The central dogma of biology describes the flow of information in a cell. In Lab 3.2 we analyzed data to see how a mutation in a gene affects the rate of cell division. Mitosis and Meiosis are two forms of cell division in eukaryotic cells. Here in Lab 3.2 we focused on Mitosis. Mitosis is when one cell, the parent cell, divides to...

...2.3 The other 3 sources Aside from the five most basic issue ranges, we have secured above, three other incessant wellsprings of problematic specimen quality found in Hospital Serdand are those connected with blood gas analysis, blood culture and urine specimens. 2.3.1 Blood Gas Specimens Whilst the centralization of heparin in most blood gas syringes is higher than in emptied blood collection tubes, clotted specimens are a key issue and prompt expanded TAT and expanded blood gas analyzer downtime. Mixing of these specimens is troublesome because of the non-attendance of an air rising in the syringe (keeping up an anaerobic state with a non-appearance of air bubbles is obviously a necessity for a quality specimen). Mixing by reversal alone is essentially insufficient. When filled to the right level, the syringe must be "moved" between the palms of the hands for no less than 5 seconds to guarantee satisfactory mixing of the heparin anticoagulant. Mixing by reversal too is additionally suggested. The forced environment in different division likewise exhibits a huge danger of NSI in...

...definitely have more angular vibrations. Yet in the β-phase, there will be no thermal expansion because there is no such mechanisms. In this case, there is a model reflecting the transition from α to β. This model is the single order parameterthe tilt angle δ. This model is used as the PO4 tetrahedral as well as the FeO4 indiv average δ. This is defined as: δ2 = 2/3 δ0 2 [1 + (1 – ¾ (T – Tc/T0 – Tc))^1/2]. This δ0 represents the decline in the tilt angle at 980K (which is the transition temperature) and Tc signifies the temperature for the second-order transition. The average of the overall δ can also be used as the separate δ. FePO4 doesn’t have behavior the same as any other α-quartz materials and this can be seen from its quick drop of its tilt angle δ compared to the rest. PARAGRAPH 2 FePO4 will show α- FePO4 when temperature is below 980K because it has a transition temperature of 980K. In other words, a temperature above 980K would show β- FePO4. Both structures would 1 formula unit in its unit cell. However, an α- FePO4 has a trigonal unit cell while a β- FePO4 has a hexagonal unit cell. Table 2 shows the unit cell parameters and the volume of FePO4 and its correspondence with temperature. The table shows that there are changes to the structure of the cells as the temperature changes. The cell parameters increases significantly and instantly as the temperature increases, and cell volume increases along with the temperature as well. This means that the c/a ratio would also...

At room temperature (about 298k), the compound will be at the phase 3 that consists of the features in a monoclinic structure and a space group of C2/m. As the temperature rises (to about 369k), the compound will then be at phase 2 and will produce a monoclinic-A2/a symmetry structure. When the temperature reaches 470k and above, the compound will be at phase 1. It will transit into a trigon structure and has a space group of R3-m.

...could do their work faster and run complex software systems. A 64-bit CPU also has more memory, it can have more than 4GB of memory compared to the 3GB - 4GB a 32-bit CPU has. This is important for downloading programs they need to use. It is also better for processing huge amounts of data at one time which is necessary for a researcher. 2. Distributed computing is a network of independent computers which communicate to achieve a goal. They do not share a memory or processors and communicate with pieces of information transferred over a network. Parallel computing uses multiple processers which each work on different things but share the same data. It was brought in to find a way around mechanical and physical restrictions on computer speed. 3....

...Chapter 3 Digital storage oscilloscope 3.1 Introduction Digital Storage Oscilloscope DSO built by Philip Cupitt . A standard oscilloscope displays variations in a voltage over time. A simple oscilloscope is of limited use for non-repeating signals .A storage scope is more advantageous as it stores the data related to signal Which can be displayed at any time. Because the screen is not continuously refreshed with the current state of the signal the scope can be used to analyze non-repeating signals. Both analogue storage and digital storage scopes are available, but digital storage are of greater use. Standard oscilloscopes use an electron beam, which is swept across a phosphor screen, the vertical deflection of the beam being proportional...

...Figure 6. The plot of the voltage through the capacitor as time increases. After assembling the basic RC circuits, the next step is assembling a circuit in Monostable mode. Since the capacitors and the resistors were measured values the only calculations needed in assembling this circuit were to figure out the values of the resistor in series with the capacitor which was found by using 30 seconds as the time and 470µF as the resistor and plugging those values into Equation 1 to get that the resistor needed was a 55.5kΩ resistor. After assembling the circuit as shown in Figure 3 the accuracy of the time it took the light to cut off (as shown in Table 2) can be acquired by calculating a percent error (as seen in Equation 6). The average percent error was 11.5% which means that with the measured resistance the time should have been 28.69 seconds and the approximate time measured by the stop watch was 31.59 seconds which is also shown in Table 1. Figure 7 illustrates the plot of the measured “time on” values in comparison to the RC time constant values. This graph shows they are proportional and therefore one can conclude that the correct...

...Exercise One Nt1310 Week 1 In: Computers and Technology Exercise One Nt1310 Week 1 NT1310:Week 1 Telecommunications By: Kenneth Martin You are an IT Network Specialist and are required to develop the design of the company’s telephone system for its new building which will begin construction in a few months. In order to get a background which will help when developing the new system, your supervisor asked you to research the current Plain Old Telephone Service (POTS) currently used by the company. You must research the system components and report back to your supervisor , the Telecommunications Manager, within a week. 1. Describe a local land line phone system based on the following Landline Telephone Components: a. Local Loop a local loop is the wired connection from a telephone company's central office in a locality to its customers' telephones at homes and businesses. This connection is usually on a pair of copper wires called twisted pair. The system was originally designed for voice transmission only using analog transmission technology on a single voice channel. Today, your computer's modem makes the conversion between analog signals and digital signals. With Integrated Services Digital Network (ISDN) or Digital Subscriber Line (DSL), the local loop can carry digital signals directly and at a much higher bandwidth than they do for voice only. b. Central Office In telephone communication in the United States, a central office (CO) is an office in a locality...

...Mason Comia NT1310 Physical Networking Unit 4 Lab April 15th 2014 NT1310 Unit 4 Lab: Building a New Structure When it comes to designing a building, it is not just all about the carpentry or the drafting and design. Yes these resources are useful but they are both based on the cable infrastructure of the building. Especially for a computer science and electrical engineering lab that requires a ton of cabling from CAT6 and RJ45. The main cable that will be used in the buildings infrastructure would probably be CAT6. CAT6 is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards. The reason for choosing CAT6 over CAT7 is because CAT7 would probably not have as much traction as CAT6. It would also be good to have matching jacks and matching patch cables. The three main tools that we would need in this project are the three types of punch down tools used to terminate telecommunications cables which are Manual, Impact, and Multi-Wire. The Manual punch down tool is a small hand tool used by telecommunication and network technicians. It is used for inserting wire into insulation-displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes. Most punch down tools are the impact type, consisting of a handle, works with a spring, and a removable slotted blade. To use the punch down tool, a wire is pre-positioned into a slotted post, and...
