Effects of drying temperature and artificial UV irradiation on the pH of veneer surfaces, water absorption, thickness swelling, as well as shear strength of plywood manufactured from untreated and treated veneer sheets were evaluated. Rotary cut veneer sheets from beech (Fagus orientalis Lipsky) log were selected. The veneer sheets were dried at either 100C or 180C after peeling. Then the sur...

Linear polarized near-infrared light (PL) irradiation is considered one of the useful methods for muscle fatigue recovery, because it increases the blood flow and skin temperature of the irradiated part. The purpose of this study was to examine the effect of PL-irradiation on muscle fatigue recovery and physiological response in the upper limbs after maximal repeated rhythmic hand gripping (RRH...

Raw ground beef patties inoculated with stationary-phase cells of Escherichia coli O157:H7, salmonellae, or Campylobacter jejuni were subjected to gamma irradiation (60Co) treatment, with doses ranging from 0 to 2.52 kGy. The influence of two levels of fat (8 to 14% [low fat] and 27 to 28% [high fat]) and temperature (frozen [-17 to -15 degrees C] and refrigerated [3 to 5 degrees C]) on the ina...

background: emulsions are thermodynamically unstable systems that can be kinetically stable by adding substances known as emulsifiers and/or thickening agents. by respect to the functional properties of gum tragacanth (gt), and its breakage probability during irradiation treatment, the major aim of this study was to investigate the stability of oil in water emulsion in the presence of different...

It has been shown that the Boltzmann equation for the viscosity of the A-phase of superfluid 3He at low temperatures has the same form as for a normal Ferrni liquid. The viscosity coefficients A, B, C, D and E are derived exactly. The h , parameter plays an important role in determining the temperature dependence of the viscosity coefficients

Biological applications where nanoparticles are used in a cell environment with laser irradiation are rapidly emerging. Investigation of the localized heating effect due to the laser irradiation on the particle is required to preclude unintended thermal effects. While bulk temperature rise can be determined using macroscale measurement methods, observation of the actual temperature within the n...

In the present study, TiO 2 /SiO 2 and TiO 2 /SiO 2 /Ag nanocomposite powders were synthesized by sol-gel technique. Moreover, for investigation of the Ag doping effect different concentrations of dopant were added. Structures were characterized by IR spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (XRD) methods. Fur...

Abstract X irradiation of sucrose single crystals at room temperature leads to the production of stable radicals, which give rise to the dosimetric electron paramagnetic resonance (EPR) signal. In the first few hours after irradiation, however, the shape of the EPR spectrum changes drastically. Based on two-dimensional field-frequency electron nuclear double resonance (FF-ENDOR) measurements, w...

An azobenzene-modified gamma-cyclodextrin stationary phase (Az gamma-CDSP) was prepared and its photo- and temperature-responses for the retention of perylene and pentacene were investigated using a mixture of methanol and water as the mobile phase in micro-HPLC. The retention of perylene slightly increased, whereas that of pentacene significantly decreased by UV light irradiation to Az gamma-C...

Temperature coefficients have been measured by 2D NMR methods for the amide and C alpha H proton chemical shifts in two globular proteins, bovine pancreatic trypsin inhibitor and hen egg-white lysozyme. The temperature-dependent changes in chemical shift are generally linear up to about 15 degrees below the global denaturation temperature, and the derived coefficients span a range of roughly -1...
