Three types of commonly used commercial treatment processes were investigated for the removal of volatile organic compounds (VOCs) from hazardous waste: thin-film evaporation, steam stripping, and distillation. These Unit operations were evaluated for their potential to control emissions from hazardous waste treatment, storage and disposal facilities (TSDFs) by reducing waste VOC content. One-d...

The IFRS Interpretations Committee (the Committee) has finally issued its Interpretation on accounting for waste removal costs IFRIC Interpretation 20 – Stripping Costs in the Production Phase of a Surface Mine (the Interpretation). This Interpretation is effective for annual periods beginning on or after 1 January 2013. Entities will be required to apply its requirements for production phase s...

We have developed two significant modifications to conventional airstripping of MTBE from contaminated groundwater. The first modification involves application of thermodynamic principles to improve by at least a factor of three the overall mass transfer efficiency, obtaining very high removal efficiencies, using a combination of higher operating temperatures (40-60 C) and vacuum pressures (fro...

OBJECTIVE To investigate how precise Descemet stripping works in posterior lamellar keratoplasty (Descemet stripping automated endothelial keratoplasty [DSAEK]) for the treatment of corneal endothelial disorders. METHODS In a prospective, single-center, nonrandomized consecutive series, 20 Descemet membrane specimens obtained after Descemet stripping in DSAEK using a Price hook were examined ...

The aim of this study was to test whether a more pronounced oxytocin release induced by naloxone during milking causes higher efficiency of milk removal. Eight pregnant multiparous Holstein cows from second to fifth lactation were used for this experiment. The experiment was carried out during three consecutive days, i.e. six milkings (three morning and three evening milkings). During first and...

Speciation modeling is an essential tool to estimate the chemical composition of an aqueous sample and to assess the bioavailability and potential risks associated with metal contamination. It is also an indispensable alternative for quantifying the metal speciation when analytical techniques are not available. In this study, we tested the effectiveness of two models, WinHumicV and the Non-Idea...

Many advanced techniques have been reported in the literature for difficult Günther Tulip filter removal. This report describes a bidirectional loop-snare technique in the setting of a fibrin scar formation around the filter leg anchors. The bidirectional loop-snare technique allows for maximal axial tension and alignment for stripping fibrin scar from the filter legs, a commonly encountered co...

We prove for a large class of operators J, including block Jacobi matrices, that if .J / n Œ ̨; ˇ is a finite set, each point of which is an eigenvalue of finite multiplicity, then a finite coefficient stripped, JN , has .JN / Œ ̨; ˇ . We use an abstract Dirichlet decoupling. Mathematics Subject Classification (2010). 47B26, 34L15, 81Q10.
