1. Synthesis and Characterization of Sec-Packings Based on Trimethylolpropane Trimethacrylate
Abstract : Suspension and bulk polymerization of trimethylolpropane trimethacrylate (TRIM) and copolymerization of TRIM with methyl methacrylate (MMA) resulted in porous, hydrophobic, and chemically crosslinked networks. Copolymerization of TRIM with acrylamide (AA) and with N,N'-methylene-bis-acrylamide (bis-AA) resulted in hydrophilic gels. READ MORE

2. Hydrolytic degradation of dental composites and effects of silane-treatment and filler fraction on compressive strength and thermal expansion of composites
Abstract : Some researchers have suggested that the weakest link of dental composites is the filler-matrix bond. However, due to incompleteness of information dealing with this bond and its stability in a humid environment, it was considered desirable to investigate the effect of water on this region, as well as the influence of filler bonding and filler fraction on compressive strength and thermal expansionExperimental composites containing different filler fractions of either silane-treated or untreated fillers were made.

3. Biophysical aspects of contact dermatitis and its prevention
Abstract : The skin, one of the largest organs of the body, is composed of three layers: the epidermis, dermis and subcutis. The outer most part of the epidermis i.e. READ MORE

4. Skin sensitivity testing : a biophysical approach
Abstract : The skin is regarded as the largest organ of the body, although it is only a few millimetres thick; it is also the interface between the environment and the body's vital structures. Its large surface area is constantly exposed to physical factors, allergens, irritants and infectious agents. READ MORE

5. Pheromones for modulating reproduction in cattle : biological potential of oestrus-related substances inintra- and inter-species chemical communication
Abstract : Declining dairy cow fertility, largely attributable to increasing milk yields, is of major concern to dairy farmers worldwide. New tools for reproductive management, to replace exogenous hormones, would be of great interest. Chemical communication in cattle has been suggested to cause modifications of the oestrous cycle.
