SundarrajanEnglish A. JeelaniEnglish V. SanthanamEnglish S. DurgadeviEnglish S. AbiramiEnglishNanoparticles find many applications due to their small size and hence enhanced physical and chemical properties. Various physical, chemical and biological methods are available for nanosynthesis and they bring some contamination to the product and hence to the environment. In order to eliminate the contamination to the environment green methods are employed for nano synthesis. The green synthesis of nanoparticles are achieved by using plant products such as leaves, roots, flowers and fruits with the precursor solution. In this work, extracts from Phyllanthus Niruri and Solanum Nigrum leaves were utilized for the synthesis of silver nanoparticles (AgNps) from silver nitrate solution. Bio active molecules present in the extract act as reducing and capping agents in the green synthesis. The bioactive components of extracts and the morphology of AgNps were studied FTIR, ultraviolet-visible spectroscopy(UV-Vis), FTIR, SEM and Dynamic Light Scattering analysis (DLS).

It is the gradual loss of the eyes ability to focus on nearby objects. The use of plus lenses to compensate for the reduction in the range of accommodation associated with presbyopia, brings the near point of accommodation to a comfortable distance for near visual task. This study is done to estimate an ideal clinical methods of measuring near addition for presbyopic patients. Material and Methods: Sixty healthy subjects with a mean age of 50 years were participatedin this study. Tentative near additions were determined usingnegative and positive relative accommodation (NRA & PRA), fused cross-cylinder (JCC) and Near Duochrome. The power of the addition was then refined to arrive at the final addition. Result: There is no statistical significant difference between near duochrome and final addition power (0.03 ± 0.50) with p-value 0.584554 whereas there is statistical significant difference between NRA PRA (0.13 ± 0.55) with p-value 0.04105 and JCC (0.33 ± 0.46) with p-value EnglishRefractive error, Accommodation, Presbyopia, Near addition, NRA PRA, Near duochrome, Jackson Cross Cylinderhttp://ijcrr.com/abstract.php?article_id=2570http://ijcrr.com/article_html.php?did=2570

Polystyrene can be foamed or solid. General-purpose polystyrene is hard, clear and rather brittle. It is a low cast resin per unit weight. It is a rather poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally transparent, but can be coloured with colourants. Uses include protective packaging (such as packing peanuts and DVD and CD cases), bottles, trays, containers, lids, tumblers, disposable cutlery and in the making of models. In the present study an attempt has been made to compute the viscosity of Polystyrene (M.W: 35000) in toluene and 1,4-Dioxane at different concentrations (0.2%, 0.4%, 0.6%, 0.8% & 1.0%) at different temperatures (303 K, 308 K, 313 K & 318 K). From these experimental data, activation energy is calculated and the effect of solvent is analyzed. Density and ultrasonic velocity have been estimated for the above systems at 303K. From these experimental values, various molecular interaction parameters like free volume, internal pressure, viscous relaxation time, inter-atomic free length, etc. are calculated and discussed in terms of solute-solvent interactions.

In this work, Dimethyl Carbonate (DMC) is mixed as an additive to the diesel as pilot fuel, with focus on reduction of harmful exhaust emissions and maintaining high Brake Thermal Efficiency. The performance and emission characteristics of the diesel engine operated with diesel fuel mixed with DMC (5%) was studied. These results were compared with the neat diesel as base fuel. The experimental study found that diesel engines fueled with DMC had improved the combustion and emission performances without significant increase in NOx emissions. By using biodiesel, there are some disadvantages such as higher density, lesser heating value, high fuel consumption and high oxides of nitrogen. To avoid above disadvantages, the fuel additives help in playing a very important role in minimizing the drawbacks of biodiesel and in maintaining international fuel standards. Additives can be considered toward to improve combustion, fuel economy and to decrease the emissions. In particular, DMC may be a promising additive for diesel fuel owing to its high oxygen content, no carbon-carbon atomic bonds, suitable boiling points and solubility in diesel fuel.
