Kerosene-based fuels have been used for many decades. Over 2 million military and civilian personnel each year are occupationally exposed to various jet fuel mixtures. Dermatitis is one of the major health concerns associated with these exposures. In the past, separate absorptio…
The wide scale use of ZnO nanoparticles (NPs) in the world consumer market has resulted in likelihood of exposure to human beings. The present study was aimed to assess the in vitro and in vivo interactions of ZnO NPs in the mammalian system and to elucidate the possible mechani…
Quantum Chemical Topology (QCT) descriptors, calculated from ab initio wave functions, have been utilised to model pKa and mutagenicity for data sets of pharmaceutically relevant compounds. The pKa of a compound is a pivotal property in both life science and chemistry since the …
The aim of this study was to develop a suitable monitoring protocol for mediated amperometric whole-cell biosensors for in situ assessment of heavy metals in soil. E. coli 8277, Pseudomonas 9773, Pseudomonas 9046 and Pseudomonas 8917 were screened as biosensor catalysts to selec…
Iron platinum (FePt) has attracted growing interest because of its high Curie temperature, magneto-crystalline anisotropy and chemical stability. Nanoparticles (NPs) made of this alloy are promising candidates for a wide range of biomedical applications including magnetic separa…
Exposure to arsenic (As)-contaminated drinking water affects tens of millions people worldwide. The health effects of As are well established yet the mechanisms and dose-response relationships of As toxicity are not fully understood. Inaccurate exposure assessment, limited sensi…
Contact mechanics of rough surfaces and surface wear will be considered. Two types of failures are considered. The first involving rapidly growing failure and the second fatigue type surface failure as a result of repetitive application of load cycle. The first type of failure w…
Phytoremediation has been proposed as a low-cost, environmentally friendly alternative to clean highly contaminated sites. Phytoremediation using trees offer the advantage of metal immobilization (phytostabilization), high hydraulic pumping pressures, produce large plant biomass…
The Blackside Dace (Chrosomus cumberlandensis; BSD) is a federally threatened minnow that has been extirpated from 31 streams in Tennessee and Kentucky since 1978. Although there is strong evidence linking elevated conductivity levels and low BSD occurrence, the mechanistic rela…
For over a century, Sudbury (Ontario, Canada) has been a major copper-nickel metal smelter centre. Emissions of acidifying compounds and metal particulates beginning in the 1880s damaged thousands of lakes and watersheds in the region. Emission controls introduced in the 1960s a…
