An efficient method for the preparation of 5-substituted 1H-tetrazole derivatives is reported using MoO3-SiO2 as an efficient heterogeneous catalyst. This method has the advantages of high yields, simple methodology and easy work-up. This catalyst could be recycled very easily, which makes this methodology environmentally benign.

Although several studies have documented challenges related to inadequate adherence to antiretroviral therapy (ART) and high loss to follow-up (LTFU) among Option B+ women, there is limited understanding of why these challenges occur and how to address them. This qualitative study examines women's experiences with ART adherence and retention in care. Between July and October 2015, in-depth inte...

The theme of the present study is to stress the importance of duration of warm-up exercise on respiratory functions in athletes. Significant improvements in athletic performance was achieved due to warm-up exercise owing to increase in blood flow, muscle and core temperature. The optimum intensity and duration are required to bring about the desired warm-up. A close examination on respiratory f...

This Coastal and Hydraulic Engineering Technical Note (CHETN) summarizes the state of understanding of the influence of grain size on surf zone sediment transport and is a companion to Smith et al. (2004). This CHETN discusses details of bed-load and suspended load transport, and the classical bed-load regime is shown to encompass two distinct modes of transport. Four LST models with varying le...

2012 ACKNOWLEDGMENTS I would like to thank all people which have made this work possible. I express my sincere gratitude to my supervisor, Professor Militon Frent¸iu, for his help during these years. I also thank Professor Horia F. Pop for research opportunities offered and valuable ideas. The passion for research, encouragements and many ideas came from my coleague Andreea Vescan to whom I am ...

Revised We present four-dimensional and ¯ve-dimensional models for classical cross-coupled LC oscil-lators. Using these models, sinusoidal oscillation condition, frequency and amplitude can be found. Further, undesired behaviors such as relaxation-mode oscillations and latchup can be explained and detected. A simple graphical design procedure is also described.

Arylation of tris(2-benzylnitrile)amine with PhLi, followed by aqueous work-up, results in the formation of a tripodal tris(ketimine) scaffold, N(ArCNHPh)(3). N(ArCNHPh)(3) readily coordinates a number of Cu(I) salts, generating complexes that exhibit trigonal pyramidal geometries in the solid-state.

Healthy walking is characterized by pronounced arm swing and axial rotation. Aging effects on gait speed, stride length and stride time variability have been previously reported, however, less is known about aging effects on arm swing and axial rotation and their relationship to age-associated gait changes during usual walking and during more challenging conditions like dual tasking. Sixty heal...
