A numerical model was used to investigate the effect of spatial variability in fracture permeability on liquid seepage and moisture distribution in the vicinity of a waste emplacement drift in the unsaturated zone (UZ) of Yucca Mountain. The model is based on a two-dimensional, cross-sectional, dual-permeability model of the unsaturated zone at Yucca Mountain and uses a stochastic approach to i...

BACKGROUND Liquid feeding system has been introduced to domestic swine farms, but negative cognition about liquid feeding system has been remained for feed waste decay related with poor management and microbial contamination. For these reasons, this study was conducted to evaluate the effects of feeding method in lactating sows. METHODS A total of 30 mixed-parity (average 4.13) lactating sows...

On-line monitoring of process and wastewater streams optimizes the control of treatment methods by providing early indications of problems that could increase discharges of hazardous compounds to the environment. On-line monitoring is important for the immediate detection and remediation of process upsets in critical streams. The waste flow to the Radioactive Liquid Waste Treatment Facility (RL...

Liquid-assisted grinding allows the rapid, waste-free and one-pot synthesis of a variety of magnesium drug derivatives directly from the excipient MgO; such reactivity is relevant for the behaviour of ibuprofen formulations involving MgO and can be used for oxide-based mechanosynthesis of metal-organic salts, discrete complexes and carboxylate clusters involving magnesium and pharmaceutically a...

A continuous end-to-end synthesis and purification of diphenhydramine hydrochloride featuring atom economy and waste minimization is described. Combining a 1:1 molar ratio of the two starting material streams (chlorodiphenylmethane and N,N-dimethylaminoethanol) in the absence of additional solvent at high temperature gives the target compound directly as a molten salt (ionic liquid above 168 °C...

Liquid scintillation spectroscopy (LSC) is a widely used laboratory method for measuring radioactive especially low-energy alpha and beta emitter isotopes in solutions. Since the cocktails (SCs) contain large amounts of aromatic hydrocarbon compounds after LSC measurement, sample usually becomes organic waste, which challenging to manage dispose of. The most common effective waste treatment inc...

Combined Heat and Power (CHP) involves on-site or near-site generation of electricity by using gas-fired equipment along with utilization of waste thermal energy available from the power generation process and have the potential to achieve an overall system efficiency of 80% because of the utilization of thermal energy, that would otherwise be wasted, and the reduction of transmission, distribu...
