 Abstract

In India, nearly 90% of the refrigeration systems viz., domestic refrigerators, deep freezer units, food storage devices use R134a as the common working fluid. The Global Warming Potential (GWP) of R134a is high of the order of 1300. Usage of R134a refrigerant causes continuous depletion of ozone layer and global warming effect. The Chloro fluoro carbon (CFC) substances not only damages the ozone layer of atmosphere, but also bring green house effect to earth and badly affect telluric environment and human health. The Montreal and Kyoto Protocol suggested minimizing the usage of green house gases along with hydroflurocarbons (HFCs) to use as refrigerants in refrigeration system. R134a is not miscible with the lubricant oil of the compressor unit. Some of the European countries have banned the usage of R134a as refrigerant in refrigerators. The focus of this investigation is to try out and establish a suitable alternative to the conventional R134a. The proposed eco-friendly refrigerant in this work is R152a which has an advantage of zero Ozone Depleting Potential (ODP) and a significant reduced GWP value of 140 only. In this investigation three types of studies were carried out. The most commonly used commercial refrigerant R134a and the proven alternative R152a were blended and the new hybrid refrigerant was prepared and the corresponding performance of the system was investigated. The experimental results and analysis clearly indicate that there is a possibility of retrofitting the blend of R152a and R134a without any system modification. nanoadditive such as Al2O3 were blended with R152a refrigerant at 0.05% v, 0.1 % v and 0.15%v concentration were investigated. The compressor suction pressure, discharge pressure, vapour pressure, compressor input power, volumetric cooling capacity and coefficient of performance (COP) were computed and analysed. An experimental test rig is designed and fabricated indigenously in the lab to carry out these investigations. Nano refrigerant was found to work safely and with system improvement.

 Abstract

In a normal human body a balance environment is present. It is because of healthy immune system present in the body. Immune system is a complex network of cells and proteins which have ability to defend the infection acquired in body. As a result a healthy body has the ability to defeat the invading micro-organism. The invasion of microorganism is recognized with the help of developed antigens in body. In order to defend these foreign substances, antigens stimulates the production of antibodies. Monoclonal antibodies have approved applications in different types of critical and acute illness. It act as a promising treatment in the critical illness like cancer of any organ. Nowadays they are also used in treatment of infectious disorders like bacterial, viral and fungal infection. Antibodies can be prepared by different methods but large scale production of antibodies is done with the help of Hybridoma technology. In hybridoma technology clones of antibodies are prepared. Antigen firstly fused with B lymphocyte cell and then an hybrid cell is prepared in collaboration with myeloma cell to produce a defense mechanism in the form of antibodies. The main focus of writing this review is to access knowledge about what antibodies are and how they are developed for treatment of critical disorders in current scenario.

 Abstract

Nowadays, the competitiveness of the textile industry and the consumers interest have been increasing the demand for innovative and functional textiles. Along with this , sustainable developments are playing an increasingly important role in the textile industry. This led to a new development strategy based on bio-based wastes and by-products of different industries. These bio-based wastes and by-products come from several industries. These resources present an enormous potential for enhancing in the textile finish due to their intrinsic properties . This research is based on the latest innovation and textile product development through different by-products and wastes.

 Abstract

Ophthalmic drug delivery is one of the most widely used drug delivery systems for the delivery drug to eye section. In situ gels are a type of formulations in which drug is ingested in solution form and while coming in contact with body fluids or temperature, it gets converted to gel form in order to produce a sustained release formulation. The objective of present work is to develop in situ gel of ofloxacin which is an antibiotic for bacterial infections.it is a type of broad spectrum antibiotic. It has a low molecular weight of 361.368gm/mol. It is one of the most suitable candidates for ophthalmic drug delivery. Ofloxacin is an antibiotic that is used to treat bacterial infections; it stops the multiplication of bacteria by inhibiting the reproduction and repair of their genetic material (DNA).Marketed eye drop solution is cleared very rapidly from the corneal region whereas, in-situ gelling systems, it was observed that clearing time is slow and retention of drug is for longer period at the corneal surface for a longer duration Ofloxacin can be targeted in treatment of the bacterial infection and also reduce dosing frequency, increase bioavailability of Ofloxacin that will result in better patient compliance with minimum side effects.
