As traditional competition becomes global, businesses fail to take, on their own, the measures that are required to become more competitive. Hence, in a globally competitive environment, national improvement and competitiveness have also become vital. Businesses must utilize and be supported by the international competitiveness of their nations. This study aims to analyze the competitiveness of...

In industrial textile pre-treatment and finishing processes, mass transfer and mass transport are often rate-limiting. As a result, these processes require a relatively long residence time, large amounts of water and chemicals, and are also energy-consuming. In most of these processes, diffusion and convection in the inter-yarn and intra-yarn pores of the fabric are the limiting mass transport ...

The germination process of whole seeds activates and multiplies the composition amino acids, antioxidants, vitamins, proteins, enzymes, sugars, decreases phytate protease inhibitors concentrations. Furthermore, contributes to improved digestibility plant proteins; conversion carbohydrates simpler forms for easy assimilation; bioavailability minerals; freeing up minerals absorption; an increase ...

BACKGROUND Traditionally the radiological assessment of diaphragmatic movement has relied on fluoroscopy. Ultrasound scanning has recently been shown to be a sensitive and reproducible method of assessing hemidiaphragmatic movement in normal subjects. A study was undertaken to examine how movement of the diaphragm measured by ultrasound scanning relates to inspired lung volumes measured by spir...

BACKGROUND One goal of therapeutic ultrasound is enabling heat generation in tissue. Ultrasound application protocols typically neglect these processes of absorption and backscatter/reflection at the skin/fat, fat/muscle, and muscle/bone interfaces. The aim of this study was to investigate the heating process at interfaces close to the transducer and the bone with the aid of computer simulation...

The dissipative quantum dynamics of an anharmonic oscillator coupled to a bath is studied with the purpose of elucidating the differences between the relaxation to a spin bath and to a harmonic bath. Converged results are obtained for the spin bath by the surrogate Hamiltonian approach. This method is based on constructing a system-bath Hamiltonian, with a finite but large number of spin bath m...

Bioprospecting, defined as the systematic search for valuable, molecules, genes and organisms in nature, has the potential to offer island countries a means to use biodiversity without disrupting nature; to add value to their natural resources; to ensure that such resources are protected and used in a sustainable manner; and to build the necessary skills to apply biotechnology in improving qual...
