...Part 1: Bending Water For the experiment I used a comb and various items with synthetic fiber. Being in the military I don’t have much hair to run a comb through. To begin I used a couple of throw pillows we have on our couch. Initially I didn’t see much of an effect. I tried a blanket and rubber the comb quite vigorously to make sure it would get a charge and place the comb higher near the faucet and saw the water begin to bend. I went on to continue with the balloon and it also bent the water, it was easier to bend with a balloon. Part 2: Build and use an electroscope Wonders of Our World, Electroscope. https://wow.osu.edu/experiments/Electricity/Electroscope The materials I used were a Plastic cup, aluminum foil, plain silver paper clip, plastic tape, and a balloon. I created the electroscope with guidance from the website. After completing the electroscope I used the balloon and rubbed it on my head and placed it near the top of the paperclips and saw the aluminum foil pieces spread apart. I also tried shuffling my feet with socks on the floor and didn’t get as much of a response as I did with the balloon. I tried using the comb and had another slight response with the foil separating. Since the particles are negatively charged and it’s the same current running to both pieces of foil they repel away from each other like magnets of the same...

...Then we counted the number of 3x3 unit squares, we found 4. We found each of there by starting from each corner of the Figure 1. One 3x3 unit square can be found shaded in Figure 1d. Figure 1d (3 x 3) Lastly, we counted Figure 1 as one whole 4x4 unit square, shaded in Figure 1e. When figuring out how many squares were in Figure 2, we first noticed that the first four rows represent Figure 1; therefore, we did not recount since we previously figured out there were forty squares in Figure 1. We then counted the squares formed by adding two additional rows using the same process as we did for Figure 1. We counted four squares measuring ½ x ½ units, nine squares measuring 1x1 units, six squares measuring 2x2 units, four squares measuring 3x3 units, and four...

...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...

...expansion that is very strongly nonlinear and angular variations dominated. It has a thermal expansion coefficient a which is α (K-1)= 2.924 x 10-5 + 2.920 x 10-10 ( T-300)2. The 2 contributions to the above thermal expansion include: 1. Fe-O-P bridging angles angular variations and 2. Tilt angles which are correlated If we compare FePO4 α-phase with other α-quartz materials, α-phase 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...

...compound and have different crystal structures with its own unique degree of symmetry. 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. In the article mentioned, the M3H(XO4)2 contains different symmetrical forms when it has been exposed to different temperatures. Figure 2a is one example of the compound shown in phase 3. The positioning...

...Determine which pieces of equipment are critical to the operation (can’t run without it). 2. Write PM’s on these pieces of equipment (I have a few written already) using the owners manuals as your starting point. Chances are your PM’s will look nothing like your originals once you are rolling. 3. Inventory your spare parts using the total quantities to determine the proper storage location. You want to make sure that you are not storing a bunch of “air”. Most likely you will start to run out of locations once you expand, so it is better to “right size” the parts up front the best you can. You will also continue to move parts in the storeroom as the min/max change or you determine that you do not need to stock that part anymore. 4. Determine your storeroom location labeling system and mark/label the locations so that you have a location to store the materials. 5....

...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...

...framed between 8±2°C and -17±2°C and then warms to 8±2° all within 2.5~3 hours. Picture 1 shows a design of the tryout setup for the NIRAS measurement. We put accelerometer together with the specimen at a position nearby to the end. To utilize impact loads to the specimen, we use an instrumental hammer and also tapped the specimen by an easy way in the placement nearby the other end to excite the fundamental resonance of the flexural vibration of the beam (specimen). The basic flexural resonance frequencies of specimens (28-day curing) blended with w/c ratios of 0.50, 0.55 are measured by the classical vibration theory (28): 2,125, 2,107, and 2001 Hz put in correct order from the geometry and material properties of concrete specimens (measured from the initial compression tests). The values of these measured theory are approximating the result from the tryout (please refer to table 4). We tapped the samples fifteen times with a particular strength for every tapping. We put the sample on a flexible and sof mat which enable the free rigid body motion of the sample without hitting the table on foundation. A signal conditioner manages and amplifies the vibration signals from the accelerometer to be further kept safely by an oscilloscope. Using Matlab®, frequency domain analysis for the time-domain signal is run and following the proper steps presented below, the nonlinearity parameter is extracted based on Eq. (3). How to measure the nonlinearity parameter can be referred here...
