Flight crews and air traffic controllers have reported many safety concerns regarding area navigation standard terminal arrival routes (RNAV STARs). Specifically, optimized profile descents (OPDs). However, our information sources to quantify these issues are limited to subjective reporting and timeconsuming case-by-case investigations. This work is a preliminary study into the objective perfor...

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders, affecting 5-10% of reproductive aged women. High levels of androgen hormone can be accounted as the most important symptoms in PCOS. Androgen is the precursor of steroid biosynthesis in ovary. The transport of cholesterol to the inner mitochondrial membrane through StAR protein is also necessary for andr...

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

We report thermopower measurements under hydrostatic pressure on the cuprate superconductor La$_{1.6-x}$Nd$_{0.4}$Sr$_x$CuO$_4$ (Nd-LSCO), at low-temperature in normal state accessed by suppressing superconductivity with a magnetic field up to $H = 31$ T. Using newly developed AC measurement technique suitable for high and field, we track evolution of Seebeck coefficient $S$. At ambient low tem...

indoor radon and thoron have been measured in the houses ofmoradabad district, uttar pradesh india, by means of solid state nuclear trackdetectors. radon, an invisible radioactive gas, occurs naturally in indooratmospheres and along with thoron is the most important contribution of humanexposure to natural sources. radon exists in soil gas building materials and indooratmosphere to name but a f...
