y 2015, with the proliferation of wireless multimedia applications and services (e.g., mobile TV, video on demand, online video repositories, immersive video interaction, peer to peer video streaming, and interactive video gaming), and anytime anywhere communication, the number of smartphones and tablets will exceed 6.5 billion as the most common web access devices. Data volumes in wireless mul...

This paper introduces a new Windowed Green Function (WGF) method for the numerical integral-equation solution of problems of electromagnetic scattering by obstacles in presence of dielectric or conducting half-planes. The WGF method, which is based on use of smooth windowing functions and integral kernels that can be expressed directly in terms of the free-space Green function, does not require...

A formulism of frequency-domainmass diffusion-waves in porousmedia is derived bymeans of Fourier transform. In analogy to conventional thermal-wave fields, internally consistent Green functions inCartesian coordinates for linearmass diffusion-waves is also presented for infinite, semiinfinite andfinite-size domains in three-dimensional spaces. TheGreen functions are utilized to analyze the resp...

Recent advancements in nanotechnology have originated the new emerging heat transfer fluids called nanofluids. Nanofluids are prepared by dispersing and stably suspending nanometer sized solid particles in conventional heat transfer fluids. Past researches have shown that a very small amount of suspending nanoparticles have the potential to enhance the thermo physical, transport and radiative p...

BACKGROUND Given its availability and low price, glycerol derived from biodiesel industry has become an ideal feedstock for the production of fuels and chemicals. A solution to reduce the negative environmental problems and the cost of biodiesel is to use crude glycerol as carbon source for microbial growth media in order to produce valuable organic chemicals. In the present paper, crude glycer...

A new efficient heterogeneous catalyst was introduced for the epoxidation of styrene. The catalyst was obtained from functionalization of cellulose with N-(2-aminoethyl)acetamide, and then deposition of nanoparticles and Pd(0) nanoparticles on the modified cellulose. The Fe3O4 nanoparticles were deposited via chemical oxidation in basic media and Pd(0) nanoparticles we...

Dihydrorhodamine (DHR) 123 is a fluorophore commonly used for measuring reactive oxygen species (ROS), often after exposing cells to ultraviolet (UV) irradiation or oxidative burst inducers such as Phorbol 12-myristate 13-acetate (PMA). However, the negative effects of UV irradiation on oxidation of DHR123 itself to green fluorescence rhodamine (R) 123 under different experimental conditions (e...

Stability of tea catechins during heat processing was exarnined. Effects of pH and temperature on reaction kinetics of degradation of tea catechins were investigated. Reaction of -EC was accelerated at pH higher than 6.0, inhibited at those lewer than 5.0. A dominant reaction of --EC in slightly acidic media was isomerization. The apparent first order reaction proceeded in slightly acidic media...

The current study envisages producing Cordyline plants on a large scale employing costeffective In vitro protocols. The effect of various concentrations and types of plant growth regulators were observed to optimize the efficient media for propagation. Axillary buds excised from the greenhouse grown mother plants of Cordyline terminalis were cultured on MS medium supplemented with BAP (1.0-2.0 ...
