Several studies have demonstrated that blacks exhibit elevations in systemic oxidative stress. However, the source(s) and mechanism(s) contributing to the elevation in oxidative stress remain unclear. Given that peripheral blood mononuclear cells (PBMCs) can be a major source of NADPH oxidase-derived superoxide production, we tested the hypothesis that young black men demonstrate greater supero...

The liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like Standard Penetration Test (SPT), Cone Penetration Test (CPT) and Shear Wave Velocity (Vs). In this regard, this study attempts to compare the results of the SPT based on the simplified procedure proposed by Seed and Idriss...

Combinatorial match in production systems (rule-based system) is problematical in several areas of production system application: real-time performance, learning new productions for performance improvement. modeling human cognition. and parallelization. The unique-attribute representation in production systems is a promising approach to eliminate match combinatorics. Earlier investigations have...

The world trade collapsed in the most recent recession. Some analysts have suggested the increasing offshoring of the supply chain, or vertical specialization (VS) trade, can explain the apparent increase in volatility of trade over the business cycle. This paper develops a model of VS trade to examine its impact on the volatility of trade. The model features increased trade volatility as VS tr...

A novice engineer often faces many difficulties during the design of liquid retaining structures, which involve making many decisions on the basis of judgment, heuristics, code of practice, rules of thumb, and previous experience. There is a need to develop programming environments that can incorporate engineering judgment along with algorithmic tools. In this paper, the development of a web-ba...

Many systems based on knowledge, especially expert systems for medical decision support have been developed. Only systems are based on production rules, and cannot learn and evolve only by updating them. In addition, taking into account several criteria induces an exorbitant number of rules to be injected into the system. It becomes difficult to translate medical knowledge or a support decision...

Pathogenic factors that may contribute to hypertriglyceridemia were studied in 55 patients who have been undergoing chronic hemodialysis treatment. Increased levels of triglyceride were observed in the patient group compared to normal controls (19o±93 mg/dL vs. 121±45 mg/dL, p<O.05). Similarly, augmented concentrations of VLDL-C were observed among patients compared to the control subjects...

Dog rose (Rosa canina L.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as Rosa hybrid and Rosa floribunda. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and d...

Each organization has limited resources and in order to better accomplish a higher external demand, the managers are forced to outsource parts of their contracts even to concurrent organizations. In this concurrent environment each organization wants to preserve its decision autonomy and to disclose as little as possible from its business information. To model this interaction our approach is t...
