Hydrogen, a clean energy carrier with high energy capacity, is a very promising candidate as a primary energy source for the future. Photoelectrochemical (PEC) hydrogen production from renewable biomass derivatives and water is one of the most promising approaches to producing green chemical fuel. Compared to water splitting, hydrogen production from renewable biomass derivatives and water thro...

Peritoneal exudate cells (PEC) from mice inoculated 5 to 7 days previously with 1 X 10(6) MOPC-315 plasmacytoma cells exhibit in vitro migration-inhibitory factor reactivity to soluble tumor-associated antigens. By 10 to 14 days of tumor growth, PEC from MOPC-315-bearing mice did not elicit migration-inhibitory factor when stimulated with MOPC-315 tumor-associated antigens but were still capabl...

The role of MHC products in the induction of DTH responses Ia antigens play a crucial role in these cells in the recognition of ABA determinants by lymphocytes. Second, JY-1 guinea pigs were employed as responder animals. A clear allorestriction phenomenon was observed again when weakly modified ABA-PEC were used. On the other hand, the allorestriction phenomenon was apparently abrogated when h...

The effects of mecillinam, trimethoprim and ciprofloxacin, antibiotics used in the treatment of urinary tract infections, on the aquatic environment were assessed. Mecillinam and ciprofloxacin were both readily biodegradable (primary degradation) in activated sludge, whereas trimethoprim persisted. The toxicity of these antibiotics towards sludge bacteria, a green alga, a cyanobacterium, a crus...

In this research, a probabilistic estimation compensation (PEC) method for fixed-width Booth multiplier is proposed. According to the probabilistic analysis for the truncation part,a formula is obtained to calculate the compensation value easily. In the application of long bit width, the PEC method is implemented by a simple compensation circuit without the exhaustive simulation to achieve a hi...

The analysis of mitochondrial DNA (mtDNA) has proven useful in forensic genetics and ancient DNA (aDNA) studies, where specimens are often highly compromised and DNA quality and quantity are low. In forensic genetics, the mtDNA control region (CR) is commonly sequenced using established Sanger-type Sequencing (STS) protocols involving fragment sizes down to approximately 150 base pairs (bp). Re...

OBJECTIVES This paper tried to review a recent research trend for the environmental exposure of engineered nanomaterials (ENMs) and its removal efficiency in the nanowaste treatment plants. METHODS The studies on the predicted environmental concentrations (PEC) of ENMs obtained by exposure modeling and treatment (or removal) efficiency in nanowaste treatment facilities, such as wastewater tre...

One of these testers, a 1980’s vintage logic test system required upgrading due to maintenance and obsolescence issues. The system had 64-Pin Electronics Cards (PEC), each with one Parametric Measurement Unit (PMU) and one functional channel for a total of 64 tester channels. A new PEC, designed by Fairchild with the assistance of students and staff of the University of New Hampshire, needed a ...
