In recent decades, engineered membranes have become a viable separation technology for a wide range of applications in environmental, food and biomedical fields. Membranes are now competitive compared to conventional techniques such as adsorption, ion exchangers and sand filters. The main advantage of membrane technology is the fact that it works without the addition of any chemicals, with rela...

It is numerically shown that the groundstate ofthe Friedel problem (consisting of a conduction band and a d­ resonance), occupied with (n+ I) electrons, can be written as If/ = (Aoo+Bd*) rr=1 o~Po, where ail represents a localized conduction electron state, d* is the Friedel resonance state and TI~=1 a7,po is a Slater determinant of n single electron states it7, (po is the vacuum state). The 07...

A physically accurate model for charge transport in graphene is given by a semiclassical Boltzmann equation whose scattering terms have been deeply analyzed in the last decade. Due to the computational difficulties, the most part of the available solutions have been obtained with direct Monte Carlo simulations. The aim of this work is to simulate a monolayer graphene on a substrate, as, for ins...

In this work, the mechanical exfoliation method has been utilized to fabricate Bi2Te3 ultrathin films. The thickness of the ultrathin films is revealed to be several tens of nanometers. Weak antilocalization effects and Shubnikov de Haas oscillations have been observed in the magneto-transport measurements on individual films with different thickness, and the two-dimensional surface conduction ...

Guillain-Barré syndrome (GBS) usually presents in a symmetrical ascending fashion of weakness. We present a 6-month-old male infant who presented to our emergency room with acute left-sided limb weakness and head lag 3 days after a febrile upper respiratory tract infection. A diagnosis of GBS was established by confirming high cerebrospinal fluid protein, motor nerve reduced amplitude, and prol...

The second law of thermodynamics governs the direction of heat transport, which provides the foundational definition of thermodynamic Clausius entropy. The definitions of entropy are further generalized for the phenomenological heat transport models in the frameworks of classical irreversible thermodynamics and extended irreversible thermodynamics (EIT). In this work, entropic functions from ma...

OBJECTIVES The diagnostic utility and reliability of an easy-to-operate novel handheld nerve conduction tester in carpal tunnel syndrome (CTS) were evaluated. MATERIALS AND METHODS Using the test device, the sensory nerve conductions (SNC) in the median and ulnar nerves were compared with each other in 194 patients with suspected CTS and 95 healthy controls. The test device results were compa...
