A typical dynamometer drive shaft was damaged during its working condition. This failure was repeated in four cases. In the present article, a failure analysis of a dynamometer drive shaft has been performed. To analyze the failure, the material investigation was carried out by scanning electron microscopy (SEM) images. Additionally, the micro-structure of the failed coupling shaft was photogra...

sunitinib is an oral tyrosine kinase inhibitor which prevents tumor growth and metastatic progression. it was approved for treatment of advanced renal cell cancer, gastrointestinal stromal tumor and advanced pancreatic neuroendocrine tumors. it has several adverse reactions on multi organ systems including hematologic system. although the neutropenia and thrombocytopenia commonly happens as gra...

in the present study, a model of a large lithium polymer (li-po) battery for use in the simulation of hybrid electric vehicles (hevs) is developed. to attain this goal, an equivalent circuit (ec) consisting of a series resistor and two rc parallel networks is considered. the accuracy and the response time of the model for use in an hev simulator are studied. the battery parameters identificatio...

Progression through G2 phase of the cell cycle is a technically difficult area of cell biology to study due to the lack of physical markers specific to this phase. The FUCCI system uses the biology of the cell cycle to drive fluorescence in select phases of the cell cycle. Similarly, a commercially available system has used a fluorescent analog of the Cyclin B1 protein to visualize cells from l...

Test methods and data acquisition system specifications are described for measurements of the energy consumption of the control system of a servo-pump continuously variable transmission (CVT). Dynamic measurements of the power consumption of the servopump CVT control system show that the control system draws approximately 18.9 W-hrs of electrical energy over the HWFET cycle and 13.6 W-hrs over ...

We design an RSFQ oscillator with a variable duty cycle to drive a superconductive qubit. This design has been optimized to minimize the decoherence when coupled to the superconductive persistent current qubit. A continuous RSFQ ring oscillator reads the contents of a Non-Destructive Read Out memory cell. By using two out-of-phase counters to Set and Reset the cell, we can vary the duty cycle o...

The eukaryotic cell-division cycle is regulated by three modules that control G(1)/S, G(2)/M and meta/anaphase transitions. By using mathematical modelling, we show the dynamic characteristics of these individual modules and we also assemble them together into a comprehensive model of the eukaryotic cell-division cycle. With this comprehensive model, we also discuss the mechanisms by which diff...

Drive and motivation are central to affective neuroscience. Here, we describe the development of conceptualizations from early behaviorist theories to contemporary theories linking motivation closely to reward. Current experimental data suggest key roles of drive and motivation in the wanting, liking, and learning processes underlying the pleasure cycle supporting survival of individuals and sp...

objective: in an attempt to develop safer and more effective gene therapy approaches as a realistic treatment for various forms of cancer, researchers are increasingly using tumor-specific promoters (tsp) to drive the expression of the gene of interest and eradicate cancer cells. in this study, for the first time we introduce the oct-4 promoter as a cancer-specific promoter with a high efficacy...
