Obsolete hardware can be effectively reused through intelligent software optimization, which is possible only when source code is available. Virtual Distro Dispatcher (VDD) is a system that produces virtual machines on a central server and projects them on a number of costless physical terminals. VDD is the result of an extreme software optimisation based on virtualization and terminal servers....

Recent studies report a high prevalence of vitamin D deficiency (VDD) among patients with sickle cell disease (SCD), with rates as high as 65–100% depending on the season (Buison et al, 2004; Lal et al, 2006; Adewoye et al, 2008; Rovner et al, 2008; Chapelon et al, 2009). Despite this evidence, VDD remains both under-recognized and under-treated in patients with SCD. There appears to be substan...

INTRODUCTION AND OBJECTIVES Single-lead VDD pacing provides the physiological benefits of atrioventricular synchrony with the convenience of a single-lead system. However, concern remains about the method's safety and effectiveness. METHOD In total, 700 patients with single-lead VDD pacemakers were evaluated retrospectively. The following parameters were recorded: age, sex, etiology, the symp...

Background: Vitamin D deficiency (VDD) in pregnancy has been found to be associated with adverse outcome various observational studies. Evidence from randomized control trials is necessary change current recommendations. Aims and Objectives: We conducted controlled trial assess the effect of supplementation on outcome. also looked for predictors VDD as universal testing neither recommended nor ...

<b>Background: </b>Vitamin D deficiency (VDD) is the one of major public health problem affecting approximately billion people all over world. In recent years, relationship allergic diseases with a low concentration vitamin has been studied worldwide. An association found between small count serum and development immune disorders. Patients disorders and, in particular, respiratory a...

A pure CMOS threshold voltage reference (VTR) circuit achieves temperature(T) coefficient of 5 μV/°C (T=-60~+100 °C) and supply voltage(VDD) sensitivity of 0.1 mV/V (VDD=3~5 V). The combination of subthreshold current characteristics and different operating modes in n-MOSFETs provides a small voltage and temperature dependence. A feedback scheme from the reference output to gates of n-MOSFETs n...

Lowering VDD during standby mode reduces power by decreasing both voltage and current. Measurements of a 0.13 m testchip show that reducing VDD to near the point where state is lost gives the best power savings. We propose closed-loop voltage scaling that uses “canary” flip-flops for achieving these savings. This approach provides over 2X higher savings than optimal open-loop approaches without...

Sensors with long lifetimes create new applications in medical, infrastructure and environmental monitoring. Due to volume constraints, sensor systems are often capable of storing only small amounts of energy. Several systems have increased lifetime through VDD scaling [1][2][3]. This necessitates voltage conversion from highervoltage storage elements, such as batteries and fuel cells. Power is...

Increasing evidence indicates that vitamin D deficiency exacerbates chronic kidney injury, but its effects on renal enlargement in polycystic kidney disease (PKD) are not known. In this study, male Lewis polycystic kidney disease (LPK) rats received a normal diet (ND; AIN-93G) supplemented with or without cholecalciferol (vitamin D-deficient diet, VDD; both 0.5% calcium), commenced at either po...

BACKGROUND Atrial endocrine function was established in the second half of the 20th century, confirming the role of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) in the physiology of the cardiovascular system. The present study was undertaken to evaluate changes in ANP and echocardiographic parameters within the first month after VVI and DDD pacemaker implantation and to ...
