Figure 5.8 is a pulse height spectrum of the net counts of the beta- emitting radionuclide, 137Cs as a function of pulse height voltage. Within Figure 5.8, the majority of the counts reside in the low voltage region, below 25 mV. It is possible to discriminate the between the different particle types by virtue of the pulse height distribution and establishing detection window threshold within the detection unit. As discussed earlier, it is possible to establish a lower threshold limit that…

Introduction Sime Darby is one of the successful company that have been operating in over 20 countries world-wide and has more than 100,000 employees. In 2009, Sime Darby take the initiative to introduction ‘Sime Darby’s Core Executive Program’, (CEP) this program is been encourage by the company for employee self-actualization. The aims of this CEP is to increase the self-awareness and personal mastery in their executives and senior executives. This CEP has reached out to Thailand and brings…

Entitled Americans: How our Excessive Food Waste Contributes to Climate Change Briana Clementz Denver South high school Spring 2017  Abstract How large of an impact does the food we waste have on the environment? Or better yet, how much food do we actually waste annually? According to Ira Flatow of NPR, we waste approximately 33 million tons of food in the United States every single year. By using scientific and argumentative resources, I was able to research just how large of an impact…

Kinetic investigation and the Arrhenius plot The degradation of SAC in acidic, basic and oxidative mediums at different HCl (0.01, 0.05 and 0.1 M, keeping temperature 90 ºC), NaOH (0.005, 0.01 and 0.05 M, keeping temperature 40 ºC) and H2O2 (5%, 10% and 15%, keeping temperature 90 ºC) strengths was studied. Also SAC degradation was studied as a function of temperature in acidic (30, 60, 70, 90ºC and room temperature, keeping HCl strength 0.1M), basic (40, 65, 90ºC and room temperature, keeping…

“The Guns and Soul of America,” David Brooks, Oct. 6, 2017 The piece “The Guns and Soul of America” by David Brooks, questions the seemingly obvious belief: that as there is an increase in violent deaths and mass shootings involving privately owned firearms, there should also be an increase in stricter gun laws, and a downturn in popular opinion regarding gun ownership. Instead, in his column, Brooks writes to prove that the opposite is the case - that as the instances of mass shootings occur,…

For as long as I can remember, I have been fascinated with forensic science and I distinctly remember my brother and I running home from the bus stop every day, when we were in middle school, just so we would not miss the introductory scene of the new Criminal Minds episode. The show always began right at 3 and our bus got to the stop roughly around 2:55; just enough time to run home and turn it to the right channel. And as any fan of Criminal Minds knows, the beginning is the most captivating…

The overall project, once completed, would help the company to quantify smells and tastes in a meaningful manner, increasing standardization of the process and enhancing the use of data and statistical measures for use by the company. The evidence showed that the company was trying to compete in the smell and taste marketplace. Because of this, they wanted to improve their measurement system that was used to measure taste and smell. Additionally, in the define phase, they have mentioned their…

Synthesis and characterisation of conjugates Conjugation of CpG to antigen as a means for co-delivery has been shown to enhance cellular immune responses compared to delivery as a mixture. The ODN CpG however can be conjugated via its 3’ or 5’ end, and blocking of the 5’ end has been described to reduce its immunostimmulatory properties in splenocytes. To determine whether the end of CpG conjugated to OVA effects the induction of a cellular immune response by an immunotherapeutic vaccine, CpG…

Thus, it is essential to identify gene/biomarkers that can distinguish patients with high and low risks of recurrence (Zhi, et al., 2016; Zhong, et al., 2016). RNA quantification enables us to understand the switch on and off of a particular gene, i.e., gene expression. Expression profiling of RNA explains the real-time activity of cells along with its expressed genes in those concerned cells. Microarrays mainly deal with…

Chapter 2 (Cadmium) NG Ka Yan 2.1 Introduction Cadmium(Cd) is toxic which can affect human health at low levels, and it is a carcinogen. Cd cause cancer which is lung, kidney and prostate cancer. Cd leads cancer because of the oxidative stress. Oxidative stress involved the Cd-induced aberrant gene expression, apoptosis and inhibit the DNA damage repair. Besides, Cd trigger the reactive oxygen species (ROS) formations by producing cellular thiol redox imbalance, and that make intracellular…
