Abstract :

Laboratory experiments were carried out to evaluate the activity of Colocynth (cucurbitaceae) leaf powder and leaf chloroform extract against the house fly (Musca domestica L.) larvae and pupae. Addition of Colocynth leaf powder to the food of House fly larvae caused dose –dependant reduction in larvae weight, faster development to pupae with subsequent reduction in number of emerged adults especially at high dose. Further dipping of house fly pupae in leaf chloroform extracts, caused significant delay and reduction in number of emerged adults .

    Generally, the result indicated the presence of antifeedant and growth regulatory agent in the examined members of the family cucurbitaceae. Further lines of research were outlined.

Abstract :

The research presented in this memory was carried out at the Institute Pasteur in Côte d'Ivoire and carried out on E. coli and Salmonella spp. The objective of this study was to isolate E. coli and Salmonella spp. strains resistant to antibiotics from wastewater from the Port-Bouët slaughterhouse. From September 2017 to March 2018, 17 strains of E. coli and 7 Salmonella spp. were isolated in 63 samples of wastewater collected at the slaughterhouse of Port-Bouët. Their identification was performed according to conventional bacteriological tests. An antibiogram according to the disk diffusion method was carried out for 21 antibiotics used in human and veterinary medicine. The prevalence observed was 26.98% for E coli strains. and 11.11% for Salmonella spp. All strains of E. coli showed complete (100%) resistance to 3rd generation cephalosporins, aztreonam, amoxicillin + clavulanic acid, and ampicillin. However, family resistance rates of quinolones, aminoglycosides, sulfonamides and cyclins remain very high. The sensitivity of E. coli to imipenem and amikacin was 100%. Salmonella spp. strains, on the other hand, were resistant only to beta-lactam at lower levels compared to E. coli strains. coli. In-depth studies are needed to determine the resistance mechanisms of these bacteria..

Title : Passive Modification of a Heat Exchanger using Spherical Turbulators

Abstract :

Heat exchangers can be enhanced by different kinds of methods, namely Active, Passive, and Compound methods. Active Methods involve supply of external power to increase the rate of heat transfer. While constructing such heat exchangers leads to a rather complex design, external power is not easy to provide in certain scenarios.

Passive Methods do not need any external power supply and improve the efficiency of the heat transfer through structural alterations. This, however, leads to utilization of energy from the available energy in the heat exchanger, thereby leading to an increased pressure drop. It has been the aim of all the scientists to obtain greater thermal contact i.e., increased heat transfer coefficient and lower pumping power.

The Passive Technique being discussed below involves the use of surface extensions. The surface extensions are further referred to as turbulators, and because of their spherical cross-section, they are conveniently termed as spherical turbulators. These Spherical Turbulators cause blockages in the flow passage. This leads to enhanced secondary flow and due to the increased surface area as well, there is an improvement in the overall heat transfer coefficient—which is manifested by an increase in the outlet temperature of the fluid to be heated and the Nusselt Number.

Title : A Concept to Approach Demand and Supply in a Different Way

Abstract :

The purpose of writing this research paper is to investigate the applications, limitations and benefits of demand and supply framework. Antoine Augustin discovered the economic model of demand and supply in 1838. His model works on the fundamental laws of demand and supply. Today many government policies and private firm decisions are taken after constructing and analyzing the demand and supply of their niche. However, the model is too simplistic and the applications of demand and supply shown by this framework is to an extent bend towards theoretical use then practical gains. In this ever-changing world, where business are becoming adaptively creative and the everyday market is becoming unpredictable, I believe that relying on a model which is centuries old  may not help the upcoming business to grow and evolve. During 1800s, trading use to occur in a uniform manner and different markets use to grow in a linear, passive fashion. In this current era, demand is completely unpredictable because of the high competition and available substitutes. I believe every business toady have the power of some price discrimination or else a business will start losing the potential customers and may soon shut down. Prices today play a very small role in the process of trading, and that there are many factors other than price which determines the level of demand at a particular time period. These other factor play a big role in setting the equilibrium prices. For different situations, different prices will have to be charged by a business to keep the demand up to a level of supply. 

In this paper, I will demonstrate a way to view how does the practical world works in different equilibriums and situations by constructing a new model. In order to depict a practical market, ceteris paribus will have to be eliminated. Equilibrium in this new framework will be reached with not keeping things constant but with the factors, that influences price.

The new framework will be critically analyzed, evaluated and be compared with the existing economic models. The new framework will be an improvement to the existing economic models, as it will demonstrate different those concepts, which are not portrayed by the existing model such as the concept of market gap.

If I am able to prove my framework by providing concrete limitations of the existing demand and supply model and how are the old models limited to only theoretical use, I can then conclude by providing significant benefits to relying on the new theory. The aim of this report is to find a unique alternative of demand and supply, which will be more accurate and reliable in the real life scenarios.

Abstract :

The Fe3O4@SiO2@PLL core-shell nanoparticles were prepared by functionalization of magnetic Fe3O4 nanoparticles with 3-amidyl trimethoxane (APTMS) and Poly(L-lysine) (PLL) as a novel sorbent for heavy metal ion removal in water. The Fe3O4@SiO2@PLL nanoparticles were prepared by a three-step process: (i) surface modification of Fe3O4 nanoparticles by APTMS to form Fe3O4@SiO2, (ii) surface functionalization of Fe3O4@SiO2 nanoparticles by ring opening polymerization to form a Fe3O4@SiO2@PZLL nanoparticles, and (iii) deprotection of PZLL to form the Fe3O4@SiO2@PLL nanoparticles. The chemical structure of the Fe3O4,Fe3O4@SiO2, Fe3O4@SiO2@PZLL, and Fe3O4@SiO2@PLL was characterized by FTIR and XRD. The nano-size, zeta-potential, and surface morphologies of the core-shell nanoparticles were analyzed by DLS and SEM. The core-shell nanoparticles will be further studied on their removal efficiency for heavy metal ions such as Cr2O72- (VI) from the aqueous medium, and the effects of different factors such as initial adsorbent concentration, adsorption time, adsorption dosage, pH, and temperature in the adsorption experiment will be furtherly studied.

Abstract :

This research focused on the perceived impact of the supranational institutions of the European Union (EU) over the sovereignty of its member nations. This paper also attempted to show how the EU evolved from an economic union to a monetary union that currently supervises almost all decisions made by its member states. This research analyzed various treaties, organizations and international agreements of the EU that affect the sovereignty of member states in various ways with the aid of secondary research.Secondary data from academic journals, research papers and articles was useful in understanding the real politics behind the European Union’s working. This research highlights the extent to which the EU has withdrawn the authority of its member states to make decisions for its citizens. This research found that Britain’s exit from the EU, to some extent, was fueled by the loss of sovereignty Britain felt after becoming a part of the European Union. In conclusion, the research showed that the EU had taken away the sovereignty of its member states to a great extent but it was not done intentionally – it was done in order to be able to offer the promised benefits to all its member states.

Title : Enhanced Light Trapping From Nano Particle Arrays

Authors : Sukanya R., T. Sivakumar

Cite This

Abstract :

The metal nanoparticles pocesses unique properties of light interaction .Here we focuses on incoperating these nanoparticles in thin film structers to determine their effect on light scattering and capturing in thinfilm devices. These particles can exhibit large optical field enhancements, resulting in large enhancements in the absorption or scattering of the incoming light. The interaction of light with a metal nanoparticle causes the conducting electrons in the metal to oscillate; the collective oscillation of these electrons is defined as a plasmon and results in large optical field enhancements. This phenomenon can result in either the conversion of the energy of the incident light into thermal energy via absorption or the acceleration of these electrons and subsequent radiation as scattering. Thinfilm solar cells can potentially benefit greatly from increased near-field enhancement associated with metal nanoparticles, and increased scattering can result in a greatly enhanced path length through the thin film by laterally redirecting incident light and increasing the fraction of light trapped in the film by total internal reflection.
