OBJECTIVE Determine prevalence of vitamin D deficiency (VDD) in a diverse group of women presenting for obstetrical care at two community health centers in South Carolina at latitude 32°N. METHODS AND DESIGN Any pregnant woman presenting for care at 2 community health centers was eligible to participate. Sociodemographic and clinical history were recorded. A single blood sample was taken to m...

To achieve the most energy-efficient operation, this brief presents a circuit design technique for separating the power supply voltage (VDD) of flip-flops (FFs) from that of combinational circuits, called the higher voltage FF (HVFF). Although VDD scaling can reduce the energy, the minimum operating voltage (VDDmin) of FFs prevents the operation at the optimum supply voltage that minimizes the ...

The ever-increasing chip power dissipation in SoCs has imposed great challenges on today’s circuit design. It has been shown that multiple threshold and supply voltages assignment (multi-Vth/Vdd) is an effective way to reduce power dissipation. However, most of the prior multi-Vth/Vdd optimizations are performed under deterministic conditions. With the increasing process variability that has si...

In sub-65nm CMOS technology, switching power and gate as well as subthreshold leakage power are the major components of total power dissipation. To achieve power-performance tradeoffs one varies different process (Tox, K, Vth,) and design parameters (VDD, W). Techniques for (i) dual-K and dual-Tox have been proposed to reduce gate leakage, (ii) dual (multiple)-Vth has been introduced to minimiz...

On-chip memories are one of the most power hungry components of today’s system on a chips (SoCs). The on-chip memories generally use higher supply (Vdd) and threshold (Vth) voltages than those of logic parts to suppress the static power consumption without increasing the access delay of the memories. This design policy, however, increases the dynamic power consumption since the dynamic power co...

Re-use of DDD pulse generators explanted from patients died of unrelated causes is associated with an additional cost of two transvenous leads if implanted as DDD itself, and high rate of infection according to some studies. We studied the clinical and economical aspects of reutilization of explanted DDD pacemakers programmed to VDD mode. Out of 28 patients who received VDD pacemaker during the...

The effect of mitral valve closure on left ventricular filling time and its relation to the onset of systole were assessed from mitral valve echocardiograms and simultaneous apex cardiograms in 21 normal subjects, 11 patients with left bundle branch block, and 19 patients with VDD pacemakers programmed for atrioventricular intervals of 50, 150, and 250 ms. The interval between the electrocardio...

Background: Few preclinical studies have shown that Knee osteoarthritis (KOA) is linked to gut microbiome dysbiosis and chronic inflammation. This pilot study was designed look at the composition in KOA patients normal individuals with or without vitamin D deficiency (VDD, serum <30 ng/mL). Methods: conducted prospectively 24 participants. The faecal samples of all participants were taken fo...

In this study, a novel solvent-evaporation based technology to manufacture amorphous solid dispersions (ASDs) called vacuum drum drying (VDD) was assessed in comparison the conventional technologies hot-melt extrusion (HME) and spray (SD). Ritonavir (15%w/w) embedded copovidone/sorbitan monolaurate used investigate impact on ASD quality, material properties in-vitro dissolution. All ASDs met cr...

Introduction and Aim: Vitamin D deficiency (VDD) has now become a scourge, even in sunny areas India, it is an increasing concern. The present study was prospective nature carried over period of two years (31st October 2019-1st November 2020) at the wellness clinic medical college teaching hospital research centre aimed to inquire determinants VDD representative sample. Material Methods: serum ...
