1 4 Proarammable Current Mirror A general configurable analog block (CAB) is presented, which consists of the programmable OTA, programmable capacitor and MOSFET switches. Using the CABs, the universal tunable and field programmable analog array (FPAA) can be constructed, which can realize many signal-processing functions, including filters. A prototype 5x8 CAB array has been fabricated. The ch...

during the design and development of truck cabins, the safety of the driver and the front seat passenger in an accident is an important task and should be considered. the cab must be designed in such a way that in an accident a sufficient survival space is guaranteed. the aim of this study is to investigate the behavior of iran khodro (ikco) 2624 truck subjected to a complex crash test accordin...

There is increasing awareness that how young people spend their time outside of school has consequences for their development. As part of this awareness, interest in organized activities—extracurricular activities, after-school programs, and youth organizations—has grown markedly. On balance, the bulk of research on organized activities has shown positive consequences of participation for acade...

OBJECTIVE Off-pump coronary artery bypass surgery (OPCAB) and beating-heart coronary artery bypass grafting (BH-CAB) performed with cardiopulmonary bypass support are used with increasing frequency in the treatment of coronary artery occlusive disease. The utility of OPCAB and BH-CAB in treating high-risk patients has been studied, but the effects of these procedures on ventricular function hav...

Polyethylene glycol (PEG) inhibited aggregation during refolding of bovine carbonic anhydrase B (CAB) through the formation of a nonassociating PEG-intermediate complex. Stoichiometric concentrations of PEG were required for complete recovery of active protein during refolding at aggregating conditions. For example, a PEG (Mr = 3350) to CAB molar ratio ([PEG]/[CAB]) of 2 was sufficient to inhib...

BACKGROUND Lipid-based formulations of amphotericin B (LF-AMB) are indicated for treatment of invasive fungal infections in patients intolerant to conventional amphotericin B (CAB) or with refractory infections. Physicians still may choose to administer CAB to such patients. We described the use of CAB and LF-AMB in this population and quantified differences in post-amphotericin B length of sta...

Crop protection is mostly carried out spraying active chemical agents with potential impact on the health of environment, operator and consumer. Recently the European Commission played an important role in the protection of the operator with respect to the pesticide contamination during spray application. An active protection offered by tractor cab is a new requirement when the machine is used ...

OBJECTIVES Initial androgen deprivation therapy (ADT) for metastatic prostate cancer with combined androgen blockade (luteinizing-hormone releasing hormone agonist [LHRH agonist] plus antiandrogen) is not recommended in British Columbia (BC). However, this is difficult to monitor since ADT includes concurrent antiandrogen for the first month of LHRH agonist to prevent disease flare. We describe...
