In this work, the design of hardware architecture to implement an algorithm for optimizing Hydrogen Productivity Rate (HPR) in a Microbial Electrolysis Cell (MEC) is presented. The HPR MEC maximized by golden section search conjunction with super-twisting controller. development digital implementation step optimization was developed Very High Description Language (VHDL) and synthesized Field Pr...

Biohydrogen production from starch wastewater industry via up-flow anaerobic staged reactor (UASR) was investigated. The reactor was operated at a hydraulic retention time (HRT) of 0.28 d, and different food to micro-organisms ratios (F/M) of 0.5, 0.9, 1.4, 1.9 and 2.8 g-COD/g-VSS.d. Peak hydrogen production rate (HPR) of 246 mmol-H2/L.d was observed at F/M of 1.4 g-COD/g-VSS.d. Artificial Neur...

The goal of this study was to evaluate the use expanded clay as a support material for Thermoanaerobacterium thermosaccharolyticum KKU19 produce hydrogen from oil palm trunk hydrolysate (OPT) and slaughterhouse wastewater (SHW) in fixed-bed reactor (FBR) under non-sterile conditions. effects hydraulic retention time (HRT) on performance FBR were also investigated. operated at an OPT SHW ratio 2...

N-(4-Hydroxyphenyl)retinamide (4-HPR) induces apoptosis in breast cancer cells; however, the molecular basis by which 4-HPR induces apoptosis is not well understood. In breast cancer cells, nitric oxide (NO) is predominantly an apoptotic inducer. Apoptotic agents, such as phorbol ester, tumor necrosis factor-alpha, and peptide hormones, have been shown to increase NO production in breast cancer...

BACKGROUND Bioaugmentation or an addition of the desired microorganisms or specialized microbial strains into the anaerobic digesters can enhance the performance of microbial community in the hydrogen production process. Most of the studies focused on a bioaugmentation of native microorganisms capable of producing hydrogen with the dark-fermentative hydrogen producers while information on bioau...

A high-resolution structure of the histidine-containing phosphocarrier protein (HPr) from Staphylococcus aureus was obtained by heteronuclear multidimensional nuclear magnetic resonance (NMR) spectroscopy on the basis of 1,766 structural restraints. Twenty-three hydrogen bonds in HPr could be directly detected by polarization transfer from the amide nitrogen to the carbonyl carbon involved in t...

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

Peritonitis remains a major complication of peritoneal dialysis (PD). A high peritonitis rate (HPR) affects continuous ambulatory peritoneal dialysis (CAPD) patients' technique survival and mortality. Predictors and outcomes of HPR, rather than the first peritonitis episode, were rarely studied in the Chinese population. In this study, we examined the risk factors associated with HPR and its ef...
