Extract of sample "Lap report"

Download file to see previous pages A sample holder was filled with 25ml of the sample. The UV/VIS was tuned to the wavelength for detection of the respective contaminant to be determined. A blank was run and used to zero the UV/vis spectrophotometer. Another sample holder was also filled with the sample to be studied and run at a similar wavelength as the blank. The reading of concentration in mg/L were taken and recorded for each of the samples.
When we compare, the concentrations of the four contaminants, the concentration of phosphorous reactive are very high compared to nitrate, nitrogen ammonia, and nitrite respectively. For the three samples the values of these respective contaminants are the same signifying their source could be similar according to the water characteristics table 2. From the values, it can be deducted that the samples can be considered to be from grey ...Download file to see next pagesRead More

...?Experiment North Circumpolar Motion Viewing location and other present if any ment of Purpose: The motion of stars relative to a set point, the North Star as observed from earth, raises questions concerning what is actually in motion. If the North Star remains steadfastly north, and other stars are observed moving relative to it, does the rotation of the earth fully explain the observed motion or is some other force at play. Explanation of Procedure: The experiment is set up so that observations occur in set time intervals, 90 minutes. Each observation follows this protocol: 1. Locate Polaris and plot that point on the chart, orienting the chart toward the northern horizon. 2. Use the star guide to identify and locate the Big... North...

...?Experiment #2: The Size of the Moon Viewing location and other present if any ment of Purpose: The purpose of the experiment is the measurement of the angular size of the moon. The angular size of the moon refers to the number of arc degrees the width of the moon occupies in the sky. This measurement is derived from measuring a covering circle and its distance from the observer, then applying that resulting angular size to the distance to the moon. The result is the moon’s diameter. This measure is calculated twice, once with the moon low on the horizon, and once when it is higher in the sky to test the visual sensation that the moon is larger when on the horizon. Explanation of Procedure: A meter stick was mounted at slightly... #2: The...

...?Lab report An important characteristic of most cancers is a defect in apoptosis signaling. The gradual transformation of colorectal epithelium to carcinomas is associated with a series of accumulated genetic alterations which give rise to unregulated epithelial cell proliferation as a result of a progressive inhibition of apoptosis (Bedi et al., 1995). Apoptosis is a morphologically distinct form of cell death which is under genetic control. It is also well recognized that apoptosis and the genes that control it have a strong effect on the malignant phenotype. The genes found mutated most frequently in colon cancer are adenomatous polyposis coli (APC), deleted in colon cancer (DCC), K-Ras, and p53 (Bhatnagar et al., 2009). Apart... , but has...

...A Study to Examine the Effect of Temperature on Enzymatic Activity of Amylase” Enzymes are biological catalysts, that are present in the body to carryout various metabolic activities. They are basically made up of protein molecules which are very sensitive to temperature fluctuations in the surrounding where they accomplish biological reactions. Our daily diet encompasses great quantity of starch. Hydrolysis of starch is executed by amylase, an enzyme that acts on starch to break it down into maltose, maltriose, short oligosaccharides. This paper determines the enzymatic activity of amylase over a range of temperature and thus brings a close look on the optimal temperature for amylase activities in human (human amylases...

...Experiment North Circumpolar Motion Viewing location and other present if any ment of Purpose: By tracking the apparent motions of stars relative to two set points, the North Star and the earth’s surface, the observer visualizes his relative position on the earth’s surface and appreciates the rotation of the earth. If the North Star remains on the northern horizon on the equator, then it should be visible in Denver all night between 50o – 90o in the northern sky. (That is 90oN-40o latitude Denver). (Astronomy 101) Explanation of Procedure: First, the North Star, Polaris, was located in the sky using a compass for guidance. Directly facing Polaris, the sky chart led to the location of the Big Dipper. The two locations were charted... North...

Hardenability is the measurement of the capacity of steel when hardened in depth after quenching it from its austenitizing temperature (WMT&R, 2009) . The knowledge of hardenability of steal is essential as selection of the appropriate combination of alloy steel and heat treatment to manufacture of different components of different sizes to minimise thermal stresses and distortion is dependent on this process(B.V, 1993... of Contents...

Soil Mechanics Lap Report

...Soil Mechanics Lap Report Soil is one of engineering materials, which has increasingly become very important. For any civil engineering facility, it is important to determine soil conditions as this forms an important part of the first phase. There are two methods for determining soil properties: laboratory test method and field test method. There are several laboratory tests more often performed in order to determine different characteristics of soils. These characteristics are important when it comes to designing the foundation and earth structures. This paper focuses on different laboratory tests, which were performed to determine various important mechanical properties and index of soils: Atterberg...

...Physics Lab Report Task: To determine whether a ball rolls down a decline at a constant acceleration Introduction In this experiment, members used balls on inclined rumps and tried to see whether there was any dependence on the acceleration and thereafter calculate the experimental acceleration comparing it with the theoretical acceleration. Given that theoretical slope = ½ ax and the theoretical acceleration was ax = 1.12 m/s2. Thus, the experimental acceleration at a distance of 3 meters = (1/2)a (2.24)2 where a=1.20 m/s2 (That is Xf= (1/2) ax t2) Solving for the final velocity: this was given by Xf= 0 + ½(0 + Vfx) t , Vfx = 2 Xf /t Thus the final velocity = 2(3m)/2.245 = 2.68: The experimental equation was given by...

... To Estimate the Half Layer Value for Aluminum and Wood A material’s half value layer is the thickness of that particular material where by the intensity of radiation entering the same material is reduced by half. Half layer value can also be expressed in other forms rather than the rate of intensity radiation into the material. For example the use of air karma rate. Half value layer is indirectly proportional to the attenuation coefficient. Different materials have different half value layer and half value layer is always expressed in units of distance. An increase in the penetration energy of a stream of photon or electrons always increases material half value layer. Half value layer is often applied in radiography... To Estimate the Half...

...Graph Matching _________________ Per:___ ____ Lab Partners:_____________________________ One of the most effective methods of describing motion is to plot graphs of distance vs. time or velocity vs. time. In this experiment, you will use a Motion Detector to determine this information by plotting a real time graph of your motion as you move across the classroom. The Motion Detector measures the time it takes for a high frequency sound pulse to travel from the detector to an object and back. Using this round-trip time and the speed of sound, Logger Pro determines the position of the object. It can then use the change in position to calculate the object’s velocity and acceleration. objectives Analyze the motion of a student walking...
