The problem of setting Open Shortest Path First (OSPF) weights on links such that congestion can be avoided is proved to be NP-hard. Many iterative heuristics have been applied to solve the OSPF weight setting (OSPFWS) problem. As the size of any combinatorial optimization problem increases, it becomes more difficult to find an optimum solution using sequential algorithms. In this paper, we inv...

The hydrodynamic parameters of the thermostable formyltetrahydrofolate synthetase from Clostridium thermoaceticum have been measured in the ultracentrifuge at 20”. &J,~ = 9.86 f 0.20 S;vzo = 0.752 f 0.011 cc per g; and molecular weight = 244,000 f 9,000. Calculations based on these parameters give a frictional ratio, f/f0 = 1.27 f 0.11, and a Stokes radius of 53.0 f 4.8 A. The sedimentation con...

BACKGROUND Omentin-1 is a novel adipokine expressed in visceral adipose tissue and negatively associated with insulin resistance and obesity. We aimed to study the effects of weight loss-induced improved insulin sensitivity on circulating omentin concentrations. METHODS Circulating omentin-1 (ELISA) concentration in association with metabolic variables was measured in 35 obese subjects (18 me...

vitamin e (alpha-tocopherol) is a potent and natural antioxidant. vitamin e is concentrated from soybean oil. the committee on fetus and newborn of the academy of the american of pediatrics endorsed 1 to 2 mg/dl as the normal range of serum tocopherol level. human infants are born with low stores of vitamin e, thus they require an adequate intake of vitamin e soon after birth. the optimum intra...

With advances in hemodialysis technology and the desire to achieve cardiovascular stability during dialysis, prescribed dialysate sodium concentration has gradually increased over years. Short-term trials suggest low (<138 mEq/L) is beneficial reducing interdialytic weight gain, pre- post-dialysis BP, predialysis serum sodium; but it increases intradialytic hypotensive episodes. We believe p...

In this study concept of experimental design is successfully applied for the determination of optimum condition to produce PP/SWCNT (Polypropylene/Single wall carbon nanotube) nanocomposite. Central composite design as one of experimental design techniques is employed for the optimization and statistical determination of the significant factors influencing on the tensile modulus and yield stres...

An experiment was conducted to determine the effect of hatching egg size on hatchability and hatch-weight of indigenous Venda chickens (Gallus gallus domesticus). Three different egg size groups classified into small: (<49 g) medium: (50-59 g) and large:(60-69 g) were used in the experiment. A complete randomized design was used for the experiment. Simultaneously a quadratic type equation was u...

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...

In the present paper we introduce and study finite point subsets of a special kind, called optimum distributions, in the n-dimensional unit cube. Such distributions are close related with known (δ, s, n)-nets of low discrepancy. It turns out that optimum distributions have a rich combinatorial structure. Namely, we show that optimum distributions can be characterized completely as maximum dista...
