The thermal and economic performance of parabolic trough collectors (PTCs) and PTCs with double glass envelope (DGE-PTCs) are analyzed in this work. A model including thermal and optical effects is developed to evaluate the efficiency of vacuum and a

An empirical foF2 model was constructed for the winter high-latitude ionosphere taking into account the structure of the ionization trough. This model describes the trough position and its shape in terms of longitudinal-latitudinal variations in foF2

The first decade of the 2000s saw two prolonged bear markets, both of which produced declines of over 50% in value in the S&P 500 Index from peak to trough. In total, the ten-year period from March 1999 through February 2009 saw the stock market lose

Gentamicin is commonly used in neonates, and it requires drug concentration monitoring. The objective of this study was to determine the extent of high trough (≥ 2 mg/l) and therapeutic peak serum gentamicin concentrations (5–12 mg/l) using our c
