Coulter Counter Method. Schematic Diagram Diagram 1: The basic setup of coulter counter method. Test tube containing conducting fluid placed in the beaker containing same conducting fluid. Orifice in the test tube connect the circuit. Electrodes are placed in beaker and test tube and voltage is applied. Vacuum is applied in the test tube to allow fluid movement from beaker to test tube. Counting circuit will calculate the amount of particle and pulse height analyser will measure the particle…

This experiment is purposely to study the effect of the concentration of the chemical solution on the heartbeat of the zebrafish larva. There are many advantages in using the zebrafish as the model organism. According to Gore, Monzo, Cha, Pan and Weinstein (2012), the zebrafish is commonly used as the model system of the vertebrate as it has small in size and also have the rapid development in their life. This is one of the reason of the chosen of the zebrafish as the excellent model organisms…

2.1. Theoretical Background 2.2. Material Selection Material selection plays an important role as the humidifier has to deal with a pressure of 2 Bar and temperature ranging from ambient to 90oC (maximum) and have to bare a load of 80 Newton. Simultaneously it should be lighter than aluminum and should be cheaper and fabricating time should be less and it should be capable of mass production and before all this it should serve the purpose. when developing plastic parts. Selection of an…

Discussion Leaf number, leaf area, plant height and plant spread: The effects of different levels of water stress on the growth parameters like leaf number, leaf area, plant height and plant spread of S. aethiopicum was recorded maximum in the plants grown at 100% PC. Treatments T1 and T2 (75% PC and 50% PC) did not show the significant difference, though there was drastic reduction in growth at 25% PC. Highest recording of all the parameters in 100% PC probably attributed to the optimum supply…

TLC and HPTLC Introductions Thin layer chromatography (TLC) is derived from liquid chromatography where liquid serves as mobile phase and thin layer of substance on a flat late surface serves as stationary phase. The thin layer of materials act as sorbent while the mobile phase known as solvent. Solvent will send the solutes through the sorbent depends on the strength of the mobile phase as it dissolved the solute and send them up the plate against gravity ,and resistance of sorbent…

The results of the lab show the decomposition rate of H2O2 at various amounts of KI, H2O, and H2O2. In addition, the effect of temperature on the rate of the reaction can also be seen in the results. Figure 1 Figure 2 `Figure 3 Figures 1,2 and 3 represent the results obtained from the keeping the amount of KI constant and varying the amount of H2O2 and water. It can be seen that when H2O2 is doubled (Figure 1 to Figure 2) the rate is also doubled from 0.0368 mL/s to 0.0723 mL/s. When the…

is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to the axial plane . Initial condition : P(r ,0 ,0) = P0…

Kate Byrne DT299/4 CHEM 4128 Applied Physical & Analytical Chemistry Assignment Liquid Chromatography High Resolution Mass Spectrometry Hyphenated Techniques The term “hyphenated technique” was introduced by Hirschfeld in 1980. It refers to the combination of a chromatographic separation technique and a spectroscopic detection technique to form a new, more efficent instrument. The technique which will be discussed in this case is LC-MS. The aim of combining both techniques is to purify and…

3. Results and Discussion 3.1. Temperature dependence of D.C. Electrical Resistivity The temperature dependence of the D.C. electrical resistivity of all the samples of Co-Cr ferrite system was studied using two probe method in the temperature range of 200-7000C. The resistivity of the prepared samples was calculated using the relation 1. From fig. 1 and 4, it is clear that the resistivity decreases with increasing temperature ensuring the semiconducting nature of the prepared spinel ferrites…
