Radiometric System : UTM 37n Coordinate System

The ending result of this experiment confirms that as five test tubes are lined up with the varying level of absorbance, different results in the level of absorbance will appear as well, this is visible in above table. Thus, this is due to the varying amount of water in the solution. The blank sample had a 0.30 in its level of absorbance.

The objective of this extraction experiment was to achieve a comprehensive understanding, as well as master the practice, of the technique of separating various individual components of a compound.

1. What was the view of Las Casas in relation to Spanish treatment of the indigenous people of the Indies?

5. The degree of precision was to 3 significant figures obtained with the spectrophotometer. The major source of error in our experiment was not calibrating the spectrophotometer with distilled water.

Lab one introduces the basic concepts and processes of remote sensing and gives a better understanding of multiband images, color compositing, and contrast enhancement. The following were the objectives for the lab to help introduce these concepts and processes:

In the process, extraction and distillation techniques were used. The theoretical amount of t- pentyl chloride was 17.358g, while 15.78 g was the actual amount produced which gave a percent yield of 90.9%. An error occurred while performing the experiment, the filtered dried product in the distillation process was placed in the wrong flask. Due to this that part of the experiment had to be redone and the new filtered product had some aqueous solution in it, which caused the boiling point to be under the specified temperature. The boiling point then was at 50 ℃ compared with the expected range of 79- 84 ℃. The IR spectrum used above was from another group’s results. The experimental IR spectrum has more prominent peaks in the 3000 cm-1 range compared to the expected IR spectrum. Nonetheless, the experimental IR spectrum resembles the expected IR spectrum in the sense that the peaks are closely around the same wavenumber range. This is probably due to the product being distilled at the right boiling

Using the reflectance spectrum in these three states, only, does not have high accuracy, as shown in 3, 4 and 5 Tables. However, adding derivative spectrum increases R^2 to a large extent and decreases the relative RMSE. The highest〖 R〗^2, in a 1bit method, relating to the use of the reflectance spectrum code and the derivative code is for 400-1050 nm wavelengths to 2nd order and 500-800nm to 3rd order. In the 2bit case, using the reflectance spectrum and the derivative to 3rd order, in both used wavelength, had better function and the best result for the 3rd state was in the 400-10560nm wavelength to 3rd derivative and 500-800 nm to 2nd order derivative. Deletion of the blue region from the beginning of the spectrum and regions by more than 800nm wavelength were effective in improving the results. Although using 3bit code causes lengthening the disciplinary code, among these three states, by considering the reflectance spectrum and its derivative behavior in more detailed, was more successful than the first two states to manifest the

We had difficulty in collecting the data for all the variables discussed above. We wanted quarterly data that was not seasonally adjusted. A majority of the data sets were available only for subscribed members. Other data sets were company specific so we could not access them. Below is a discussion of the variables we collected and their units of measure.

The spectrophotometer was turned on 15 min prior to the experiment. For each different intensity levels, 2 cuvettes were prepared (one for the experimental variable and one for the control variable). Also, 2 cuvettes were prepared for each different wavelength. Two blanks were prepared for the entire experiment (one for intensity, one for wavelength). The experimental cuvette for intensity consisted of 2.5 ml of 2.5 ml DCPIP, 2.0 ml water, 2.0 ml PO4 buffer, and 0.2 ml chloroplasts, a total of 6.7 ml. The control cuvette for intensity was the same as the experimental cuvette for intensity. The experimental cuvette for wavelength consisted of 2.5 ml DCPIP, 1.7 ml water, 2.0 ml PO4 buffer, and 0.5 ml chloroplasts a total of 6.7 ml. The blank cuvette intensity contained 4.5 ml of water, 2.0 ml of PO4 buffer, and 0.2 ml chloroplasts for a 6.7 ml. The wavelength blank was composed of 4.2 ml water, 2.0 ml PO4 buffer, and 0.5 ml chloroplasts for a 6.7 ml. Before starting the experiment, we set the wavelength at 600 nm, placed the blank cuvette into the spectrophotometer, and set the absorbance at zero. The laboratory was kept dark during the experiment to prevent light pollution.

The diffraction grating was used to measure the angle values of different light colors using a collimator. The wavelength of each light beam according to the corresponding color was then calculated using the specific angle value. In this procedure, a telescope was used to form an image from the diffracted light from the transmission grating. A mercury light source was also used as a light ray source of

3. The spectrophotometer was set at 420nm. Distilled water was also used as the ‘blank’.

After the hour incubation with MTT and the addition of DMSO, the blue DMSO-formazan solutions from each well was placed in a Kimex tube and run through a spectrophotometer. Each tube was placed in the spectrophotometer and had its absorbance value recorded three times. At the end, the average of each concentration was calculated.

In order to identify their textural, mineralogical changes and altered stone surfaces, images of crusts and salt samples were analyzed using (SEM JEOL JSM5500LV). They were coated with gold and a (10 KV) detector of (6587 model) was used.

My actual results and expected results were the same, my hypothesis was proven correct. Distiller A collected the most fresh water out of all the other distillers. This happened because Distiller A had the most surface area in direct sunlight, making the water evaporate more quickly than the other distillers.

concentration, record the absorbance readings at a fixed wavelength, and plot the absorbance vs. concentration data. The wavelength of 520 nm was selected for experiment Part
