slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...

INTRODUCTION.: The aim of this experimental study was to reduce the exothermic reaction during curing of the resins to cold. The significant exotherm generated by the reaction of polymerization of the resin curing involves many clinical complications including the high risk of necrosis against tooth. MATERIAL AND METHODS.: They were used four different types of self curing resins all based on ...

We calculate the Coulomb-blockade peak-spacing distribution at finite temperature using the recently introduced ‘‘universal Hamiltonian’’ to describe the e-e interactions. We show that the temperature effect is important even at kBT;0.1D (D is the single-particle mean level spacing!. This sensitivity arises because: 1! exchange reduces the minimum energy of excitation from the ground state, and...

The physics of sliding nanofriction at high temperature near the substrate melting point, TM, is so far unexplored. We conducted simulations of hard tips sliding on a prototype non-melting surface, NaCl(100), revealing two distinct and opposite phenomena for ploughing and for grazing friction in this regime. We found a frictional drop close to TM for deep ploughing and wear, but on the contrary...

We measured Raman scatterings from various single-walled carbon nanotube (SWNT) samples over a wide temperature range (4-1000 K). The G-band peaks showed clear temperature dependence, namely decrement in the Raman shift frequency and broadening of the peak width as temperature increases. The main G-band peak (G peak) showed universal temperature dependence in Raman shift for the various SWNT sa...

The purpose of the Cosmic Background Radiation (CBR) experiments is to measure the temperature anisotropy via the autocorrelation function. The partial wave l1 corresponding to the first Doppler peak caused by baryonphoton oscillations at the surface of last scattering depends on the present density Ω0 and the cosmological constant contribution ΩΛ. We discuss this dependence on the basis of per...

It is shown that the superconducting transition temperature for compounds in seven different structure types exhibits a peak at about 3.7 to 3.9 valence electrons per atom.

We consider a two-user energy harvesting multiple access channel where the temperatures of the nodes are affected by the electromagnetic waves caused by the data transmission. To protect the nodes from excess heat, power allocation policies should take into consideration the temperature of all the nodes. In this paper, we study the optimal power allocations when the temperatures of the nodes ar...

In this paper we proposed a thermal-aware scheduling algorithm for peak temperature reduction with stochastic workloads. The proposed approach consists of two steps. The first step constructs a job sequence based on the mean of the execution time of each job; and the constructed job sequence interleaves the execution of hot jobs and cool jobs. The hot job pushes up the chip temperature while th...

the aim of the study was to evaluate the effect of storage and temperature on egg physical quality in hyline chickens line. a total of 150 eggs from college of natural resources farm were sampled for the present experiment. about 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚c; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚c; relative hu...
