Introduction It is evident throughout the world today that the quality of water has become increasingly important in terms of not only ensuring that every individual has an adequate quality and quantity of the substance, but also for the maintenance and sustainability of the world’s natural environment (. However despite water quality remaining as an essential part of life for all living organisms, the influence of human developments involving farms and urban areas have brought a somewhat…

hydrogen bond formation. Similar procedure occurs in ion-dipole attraction the opposite charges of H¬2O and ion attracts to each other and equally distributes the ion within the solution. The dipole-dipole attractions give H¬2O amazing cohesion and adhesion properties. In general its polarity and the possibility of hydrogen bonding renders water many of its physical properties including higher melting point, boiling point and viscosity; and also enables water to support many life forms. Water…

As a body which was set to oversee development of the railway system, the Railway Investigation Office had the main function of carrying out studies, applying the results gotten from the studies and testing out the materials. In 1913, it became known as the Research Institute before it was restructured in 1942 as the Railway Technical Research Institute. The standards of the railway in Japan had fallen behind those of other railways around the world by 1945 (Seojima 5). This realization prompted…

Introduction Before the invention of the electronic gas sensor in the 1920s, people relied on primitive and dangerous methods. These include canaries to detect low oxygen environments in mines, and flame lights to detect methane and oxygen levels. The replacement of these methods with electronic sensors has increased both the safety and reliability of gas detection. In addition, a wider variety of gases can be sensed and quantified. Despite these improvements, issues with sensors persist.…

direction expected from gravity; this is caused by the capillary action. Capillary action arises from a combination of surface tension and adhesive forces between the liquid and the solid. The difference in intermolecular attraction in the liquid and adhesion…

allow them to be effective in growing, surviving and reproducing (Liu et al. 2015). Moreover, yeast biofilms are an interesting example of how biofilms organize in fungi. One stimulating question about yeast biofilms is discerning how growth and adhesion are affected by different ecological factors. Furthermore, this study is focused how different growth conditions…

1.0 Introduction A wire is defined as a single, flexible strand or rod of metal which is typically cylindrically-shaped. The core applications of wire, both single- or multi-stranded wire, are to withstand or carry mechanical loads in construction sector, whereas in electrical and electronic field are used to transmit electricity and telecommunications signals. For examples, from view of construction, wires are either braided or fixated together to form a bundle of strands, namely…

Hypertension and Leptin The cumulative effect of Leptin administered for short term on blood pressure in the conditions of a healthy subject are negligible. The sympathetic activity of the nervous system is activated by Leptin in lean animals (Peckett, Wright, & Riddell, 2011). However, a balance is created by the vasorelaxation that is NO-dependent and natriuresis in the event which the blood pressure is kept constant. However, prolonged hyperleptinaemia leads to an increase in the blood…

3. Nanomedicine in the treatment of cardiovascular disease 3.1 Intervention in cardiovascular disease with liposome Delivery of therapeutics to targeted tissues is possible through the design and construction of nanoscale particles while reduced toxicity as well as higher efficiency is obtainable [67,68]. Liposomes have huge skillfulness with regard to physicochemical characteristics, permitting acclimatization of the tiny particle to dovetail to the exact biological application [69]. Building…

Abstract: A one dimensional variable range hopping type conduction is observed in Poly (3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT : PSS) films and the mechanism behind enhancement in conductivity in 3% dimethyle sulfoxide (DMSO) doped PEDOT:PSS film is due to the phase segregation of PSS on the surface and reduction of energy barrier between the conducting grains. Enhanced conductivity of PEDOT:PSS films and transparency more than 80% in the visible region makes PEDOT:PSS films…
