In this research a molecular method based on polymerase chain reaction for typing of Clostridium perfringens was developed and toxin genotypes of 64 isolates from sheep and goats in Iran were determined. The PCR assays were developed for detection of alpha (cpa), beta (cpb) and epsilon (etx) toxin genes, allowing classification of the isolates into genotypes A B, C and D. The field isolates ...

A direct method called fixation is introduced for solving the general motion vision problem, arbitrary motion relative to an arbitrary environment. This method results in a linear constraint equation which explicitly expresses the rotational velocity in terms of the translational velocity. The combination of this constraint equation with the Brightness-Change Constraint Equation solves the gene...

<p style='text-indent:20px;'>The present study considers the transport discounts and capacity constraints for suppliers manufacturers simultaneously to provide a multi-objective decision-making model supplier selection on three-level supply chain. For this purpose, it begins with presenting nonlinear mixed-integer of problem, where objectives include minimization logistics costs lead time...

In this paper, a new dynamic self-adaptive multi-objective particle swarm optimization (DSAMOPSO) method is proposed to solve binary-state multi-objective reliability redundancy allocation problems (MORAPs). A combination of penalty function and modification strategies is used to handle the constraints in the MORAPs. A dynamic self-adaptive penalty function strategy is utilized to handle the co...

BACKGROUND To determine the interaction effect between APOE polymorphism and lipid concentrations and alcohol use on spontaneous deep intracerebral hemorrhage (SDICH) risks. METHODS We enrolled 217 SDICH patients and 280 controls. Anthropometrics, personal history, and concentrations of total cholesterol (TC), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol (LDL-c), ...

The use of random samples to approximate properties of geometric configurations has been an influential idea for both combinatorial and algorithmic purposes. This chapter considers two related notions—ǫ-approximations and ǫ-nets—that capture the most important quantitative properties that one would expect from a random sample with respect to an underlying geometric configuration. An example pro...
