An analytical solution for one-dimensional diffusion of chemicals under coupled chemical and thermal potentials is presented. The theoretical formulation considered includes heat conduction and chemical diffusion due to both molecular and thermal diffusion potentials. Laplace transformation technique has been used to derive the analytical solution to the problem in a semi-infinite domain. The r...

hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...

the continuous addition of industrial, municipal, and agricultural effluents to the environment has led to a great increase of toxic pollutants. it is well known that these pollutants are hazardous to animals, plants, microorganisms, and other living organisms including humans. as a result, effective technologies should be developed to remove these contaminants. biological remediation, as an ec...

Based on seven case studies of buildings that underwent different degrees of moisture and mold damage remediation, we aimed to develop methodology for assessment of the success of the remediation process. Methods used in gauging the success included technical monitoring of performance of building structures and heating, ventilation and air conditioning (HVAC) systems, microbial monitoring of in...

The acceleration of urbanization and rapid development of economy led to making surface water pollution problem becoming more critical. Water treatment technologies can be generally classified as insitu or ex-situ. In this paper, a comprehensive review describing the latest surface water remediation developments and technologies that can be suitable for in-situ applications. The review covers t...

Thermal conductive heating (TCH) is an innovative remediation technology developed for aggressive in-situ non-aqueous phase liquid (NAPL) source zone treatment. Electrical heater wells are used to conductively transfer heat into the subsurface, thereby elevating temperatures and boiling both ground water and NAPLs. The design of a TCH remediation system needs to consider the cooling effect of i...

Plasma remediation is being investigated for the removal of oxides of nitrogen (NxOy) from atmospheric pressure gas streams. In previous works we have investigated the plasma remediation of NxOy from N2 /O2 /H2O mixtures using repetitively pulsed dielectric barrier discharges. As combustion effluents contain large percentages of CO2, in this paper we discuss the consequences of CO2 in the gas m...

OBJECTIVE This study evaluated the effects of cognitive remediation for improving cognitive performance, symptoms, and psychosocial functioning in schizophrenia. METHOD A meta-analysis was conducted of 26 randomized, controlled trials of cognitive remediation in schizophrenia including 1,151 patients. RESULTS Cognitive remediation was associated with significant improvements across all thre...

In fall 2015, with leadership from the Tennessee Board of Regents, the 13 community colleges in Tennessee implemented corequisite remediation at scale for math, writing, and reading. Under the corequisite model, academically unprepared students take entry-level college courses simultaneously with remedial academic support. The corequisite model differs from the conventional approach in which re...

This observational, cross-sectional study investigates cortical signatures of developmental dyslexia, particularly from the perspective of behavioral remediation. We employed resting-state fMRI, and compared intrinsic functional connectivity (iFC) patterns of known reading regions (seeds) among three dyslexia groups characterized by (a) no remediation (current reading and spelling deficits), (b...
