In this paper the performance evaluation has been done for combinatorial code for different system and code parameters under noisy optical channel conditions for potentially increasing number of users for optical code division multiple access system. It has been observed that code weight and effective power from each user are two main factors to decide the system performance. KeywordsOptical Co...

The effect of the fibre content of lifelong (18 months) diets on proximal and distal colonic cellular proliferation and short chain fatty acid (SCFA) content was investigated in 40 rats. Rats were fed a low fibre diet (17 g/kg non-starch polysaccharides NSP) or the stock diet (133 g/kg NSP). The higher fibre fed rats had increased caecal and colonic total contents (p < 0.001) and SCFAs than the...

The understanding of skeletal muscle growth is an important goal in animal science and in human medicine. The purpose of this review is to demonstrate the importance of muscle fibre number for muscle growth and the influence of selected genetic and environmental factors on muscle fibre number. The total number of muscle fibres is mainly determined prenatally when multinucleated myofibres form f...

Several epidemiological studies link consumption of fibre-rich foods to a reduced risk of type 2 diabetes and CHD. The 'fibre hypothesis' suggested that this was a direct effect of fibre. However, fibre-rich foods contain different types of fibre as well as other potentially beneficial compounds, and many foods naturally high in fibre have low glycaemic and insulinaemic indices, possibly due to...

have a specific beneficial effect.' Fish consumption does not directly affect serum cholesterol levels significantly.6' However, the long carbon chain fatty acids present in fish have been found to reduce platelet aggregation in response to contact with the physiological stimulants collagen and adenosine diphosphate. They have therefore a mild anticoagulant effect of potential value in protecti...

The effect of the weaning diet on the subsequent colonic metabolism of bran and pectin in the adult rat has been investigated. Feeding a fibre-reduced diet on its own or supplemented with bran (WB) and pectin (P) from weaning (fibre-reduced (weaning)) was compared with introducing the same diet to age-matched rats reared on a standard laboratory diet from weaning (fibre-reduced (6 weeks)). The ...

Growing data stockpiles and storage consolidation continue to be the trend. So does the need to provide secure yet unconstrained, high bandwidth access to such repositories by geographically distributed users. Conventional data management approaches, both at the local and wide area level, are viewed as potentially inadequate to meet these challenges. This paper explores methods deploying a new ...

This paper attempts a comprehensive account of 'fibre medicine' elaborated by iatromechanists from c. 1700 to c. 1740. Fibre medicine, a medical theory informed by the notion of the fibre, has been neglected by medical historians despite the pivotal role played by the fibre in animal economy. Referring to a wide range of medical fields such as anatomy, physiology, pathology, therapeutics and li...

causative relationship is suggested by the findings of Efrain Reisin and his colleagues who showed that even if salt intake is kept constant, overweight hypertensive subjects who diet successfully have significant reductions in blood pressure.5 More specifically, Pirjo Pietinen and fellow workers undertook a comprehensive review of studies relating animal fat intake to blood pressure elevation....
