African catfish were stocked at densities of 35, 65, 95, and 125 kg/m for 60 days. The effects of the stocking density on growth, non-specific immune response, and antioxidant status were investigated on days 30 and 60. Serum cortisol levels were assayed on day 60. Increased stocking density led to decreased growth. Most non-specific immune indices (total number of leukocytes, differential leuk...

Special equipment to measure the circumferential compression exerted by an elastic stocking was used to determine the "pressure-girth profiles" of several types of elastic stocking. Once the pressure-girth profile has been determined, the pressure exerted at the ankle, calf, and thigh can be predicted for any size of limb without further pressure measurements. An excellent correlation (r = 0.96...

This paper studied a continuous-time model of a production maintenance system in which a manufacturing firm produces a single product selling some and stocking the remaining. The problem of adaptive control of a production-maintenance system with unknown deterioration has been presented. Using Liapunov technique, the production rate and updating rule of deterioration rate are derived as non-lin...

211 Effect of Photoperiods and Stocking Densities on Broilers INTRODUCTION High stocking densities and long lighting periods are two major environmental factors common to broiler production (1). The control of these factors at an optimum level not only increases commercial profitability, but also contributes to securing the supply of the human population with adequate food and animal protein. W...
