This study carried out to investigate the production of hydrogen using the organic fraction of municipal solid waste OFMSW, where the anaerobic digester was depended as a method for disposing and treating OFMSW and producing bio-hydrogen. Bio-hydrogen production had been studied under different parameters including pH, solid content T.S%, temperature and mixing ratios between the thick sludge t...
A two fluid model (TFM) was used to study gas-solid heat transfer in a riser with different inclination angles. A two dimensional pipe with 5.8 cm internal diameter and 5 meter length was chosen. Effect of bed angle and solid particles feed rate were studied on the heat transfer behavior of gas and solid particles. Obtained results from simulation are compared with the experimental data in the...
the paper presents results of experimental studies on the methane and propane ignition process in various volumetric compositions of oxidizers heated to temperatures higher than ignition point of analyzed fuels (htac conditions–high temperature air combustion conditions). the increment of temperature dt and the ignition delay time tig are parameters characterizing the process of ignition under ...
Obtaining detailed knowledge of folding intermediate and transition state (TS) structures is critical for understanding protein folding mechanisms. Comparisons between proteins adapted to survive extreme temperatures with their mesophilic homologs are likely to provide valuable information on the interactions relevant to the unfolding transition. For kinetically stable proteins such as alpha-ly...
Fitts RH. The cross-bridge cycle and skeletal muscle fatigue. J Appl Physiol 104: 551–558, 2008. First published December 27, 2007; doi:10.1152/ japplphysiol.01200.2007.—The functional correlates of fatigue observed in both animals and humans during exercise include a decline in peak force (P0), maximal velocity, and peak power. Establishing the extent to which these deleterious functional chan...
In order to increase the efficiency and working life of mettalic interconnects used in solid oxide fuel cells, protective coatings with high electrical conductivity are used. In this study, AISI 430 ferritic stainless steel was coated in a cobalt-base pack mixture by pack cementation. The effect of oxide thickness on the area specific resistance (ASR) was investigated by applying isothermal ox...
Sintering behavior of micron-sized combusted iron powder is studied in a packed bed reactor, at various temperatures under inert (nitrogen) and reducing (hydrogen) conditions. Compression tests are subsequently used to quantify the degree sintering. A sintering model, based on formation solid bridge through state surface diffusion atoms, matches experimental results. occurs ≥575°C both nitrogen...
In order to accurately calculate the sunshine-induced temperature effect of an ultra-high bridge pylon, a refined numerical simulation model for 3D field was established based on proposed automatic sunshine shadow recognition method and pylon-height-related convection modification method. A suspension H-shaped pylon with height 280 m taken as example, corresponding thermal stress deformation we...
The major factor affecting the high performance applications of the piezoresistive pressure sensor is the temperature dependence of its pressure characteristics. The influence due to temperature variation is manifested as a change in the span, bridge resistance, and offset of the sensor. In order to reduce the thermal drifts of the offset and span of the piezoresistive pressure sensor, a Half-B...
