Anaerobic digestion of sludge not only decreases the mass/volume of sludge, but also increases the production of energy-rich biogas. The effects of a thermal hydrolysis process (THP) on the solubilization of main organics of sludge, as well as the performance of the followed biochemical methane potential (BMP) tests under mesophilic condition (35 C), were systematically evaluated. Organic compo...

Abstract The upscaling of pea protein extraction from laboratory scale with a centrifuge to pilot decanter was investigated, and the efficiency dry milled pre-treated peas compared. Upscaling is possible since starch under limit detection (< 0.5%). banding pattern sodium-dodecyl-sulfate polyacrylamide gel electrophoresis confirmed that albumins globulins were extracted by alkali extraction. ...

vibration generated by vehicles during road transport has an important effect on the agricultural products damage process, particularly vegetable and fruit. modulus of elasticity is one of the most important mechanical properties of fruits and its variation can be described as one of the damage criteria during transportation. this research was conducted to evaluate the effects of vibration para...

Running agility is required for many sports and other physical tasks that demand rapid changes in body direction. Quantifying agility skill remains a challenge because measuring rapid changes of direction and quantifying agility skill from those measurements are difficult to do in ways that replicate real task/game play situations. The objectives of this study were to define and to measure agil...

Two centrifuge tests on a quay wall and cantilevered retaining with saturated granular backfills were simulated using Finn-Byrne model. Capabilities of model in liquefaction analysis the evaluated. The subjected to horizontal acceleration time history vertical history. constitutive is linear elastic – perfectly plastic Hooke’s elasticity Mohr-coulomb criterion for yield surface assumed backfill...

New Car Assessment Program (NCAP) test scores, measured by the United States Department of Transportation's (USDOT) National Highway Traffic Safety Administration (NHTSA), were analyzed in order to assess the benefits of equipping safety belt systems with pretensioners and load limiters. Safety belt pretensioners retract the safety belt almost instantly in a crash to remove excess slack. They t...

Recently, it was shown how the convergence of a class of multigrid methods for computing the stationary distribution of sparse, irreducible Markov chains can be accelerated by the addition of an outer iteration based on iterant recombination. The acceleration was performed by selecting a linear combination of previous fine-level iterateswith probability constraints to minimize the two-norm of t...

When designing 3D V-NAND technologies with a gate induced drain leakage (GIDL) assisted erase scheme, many experiments must be conducted to determine the optimal GIDL design targets achieve fast performance and secure yield characteristics. However, only limited amount of data can used since processes are time-consuming expensive in early stage development. TCAD numerical methods also require c...
