“With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2…

be seen on the high rate of incoming foreigners and unemployment in Brunei. The high rate of unemployment and incoming foreigners have interrelationship. Government spend billions of dollar on education but leave the scholar unemployed after they graduate. With the jobs vacancies in both government and private sector, most of the jobs are given to non-local even though there is still a lot of unemployed educated and skill local. In a report, Brunei has the second highest rate of unemployed…

The newsvendor problem is a mathematical model which is used to determine the optimal stock under uncertainty. In the following, the newsvendor context under cost minimization will be introduced. Let h be the unit holding cost respectively the unit overage cost (as we regard the pure cost context) and b the unit penalty of not serving demand (or unit backorder cost) respectively the unit underage cost. Then, the target inventory B is equal to the mean demand µ plus safety stock SS. The safety…

Paragraph 1 (300 - 500 words) Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4 To compare quartz, α-FePO4 and β-FePO4, it is essential to look at their crystal structures and crystal chemistry. This can be done by observing their three-dimensional structures as well as their reactions to various degrees of temperature. This particular research takes a look at the structure of FePO4 between temperatures of 294K to 1073K. At lower temperatures,…

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…

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…

of mortality rates in England (16th to 19th century AD) When researching into to the topic of mortality rates, (Scott et al, 2005) observes that it is very complex to understand the historical patterns of mortality in England and that the ‘demographic parameters of mortality decline are unclear’. Mortality rate can vary when studying various types of geographic settings, different periods of time and on the age and gender allocation of a given population. Scientist uses mortality rates in…

Paragraph 1 This paper talks about how the crystal structure of FePO4will change at different ranges of temperatures. FePO4 has a crystal structure which is similar to quartz, which is made up of 2 phases at different temperatures. At low temperature, FePO4 will demonstrate α phase till the transition temperature of 980K before demonstrating the β phase. Space group of α phase FePO4 is said to be P3121, thus suggesting it has a trigonal structure. As for β phase FePO4, the space group will be…

Freezing and crystallization are linked in that both processes involve initial nucleation followed by crystallization. Sonication is thought to enhance both the nucleation rate and rate of crystal growth in a saturated or supercooled medium by producing a large number of nucleation sites in the medium throughout the ultrasonic exposure. Two main theories which explained the mechanism of nucleation are Hickling theory and molecular segregation theory. Among two theories Hickling is most commonly…

Heart Rate This lab experiment was conducted on Daphnias to test the chemical effects on its heart rate. In this experiment we determined the effects of caffeine and alcohol on the small organism. If the Daphnia is submerged in alcohol the heart rate will slow down, as if it’s submerged in caffeine it will speed up. The experiment measured how the stimulant caffeine or alcohol affected the Daphnia. The objective was to see how alcohol and caffeine would affect the Daphnia's heart rate.…
