oxidation of low density lipoprotein (ldl) particles plays a key role in the etiology of atherosclerosis and coronary artery disease (cad). oxidative stress enhances the likelihood of ldl oxidation and atherosclerotic plaque development. paraoxonase (poni) is an enzyme associated with hdl that metabolizes organophosphates and has antioxidant activity. in order to investigate the relationship be...

background and aims. the aim was to evaluate the effect of casein phosphopeptide–amorphous calcium phosphate (cpp-acp) on microtensile bond strength (µtbs) to carious affected dentin (cad) using etch-and-rinse and self-etch adhesive systems. materials and methods. the occlusal surface of 32 human molars with moderate occlusal caries was removed. infected dentin was removed until reaching cad an...

A design methodology for the edge termination is proposed to achieve the same breakdown voltage of the non-uniform super-junction (SJ) trench metal-oxide semiconductor field-effect transistor (TMOSFET) cell structure. A simple analytical solution for the effect of charge imbalance on the termination region is suggested, and it is satisfied with the simulation of potential distribution. The dopi...

Models of propulsion motors, generators, gas turbines, and power converters are used to determine weights and volumes, evaluate designs, and predict performance of power system components for all-electric navy ships. The finite element analysis method using 3D CAD models is used to validate designs and predict performance under prescribed constraints that simulate realistic operational conditio...

In this paper, we present an embedded knowledge-base system and apply it to estimate the manufacturing cost of molded parts. This system is designed on a tiny single board computer, called the “GumstixTM”, which is an inexpensive and high-performance miniaturized platform. It consists of a knowledge-base, knowledge processing units and server service unit for user interactions, all of which are...

Running a large and complex virtual environment may require certain computational services to be implemented in a distributed manner, especially those that are relatively less time-critical, considering the network delay. An important question, therefore, is the criteria for migrating computational processes oo the main graphics rendering workstation to optimize the performance per cost in the ...

An important issue in implementation of a GIS system is preparation of data to be entered in GIS. To produce spatial data for GIS using photogrammetric techniques, conventional method is to apply photogrammetric and GIS systems individually (off-line procedure). This approach is costly, time consuming and somehow unreliable due to the fact that 3D photogrammetric model is not available at the ...

We have been developing a computer-aided detection (CAD) scheme for pneumoconiosis based on a rule-based plus artificial neural network (ANN) analysis of power spectra. In this study, we have developed three enhancement methods for the abnormal patterns to reduce false-positive and false-negative values. The image database consisted of 2 normal and 15 abnormal chest radiographs. The Internation...

background: the existing evidence suggests that plasma adiponectin concentrations can be indicative of the presence and severity of coronary artery disease (cad). however, the results of the studies conducted hitherto on this subject are inconsistent. we sought to investigate the possible correlation between plasma adiponectin levels and the presence and severity of cad in patients undergoing n...

This paper presents a prototype for an interface device which leverages the strengths of commercially available computer-aided-design (CAD) packages and the skills of pen-based designers in a single system. Using relatively conventional technology, a cathode ray tube (CRT) display and a touchscreen, the device connects the traditional skills of a designer with the power and advantages of a CAD ...
