Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj coalfield area, India. The physical, chemical, and biological parameters of the soils, and trace metals and PAHs (polycyclic aromatic hydrocarbo...

BACKGROUND Although numerous studies have demonstrated links between particulate matter (PM) and adverse health effects, the chemical components of the PM mixture that cause injury are unknown. OBJECTIVES This work characterizes spatial and temporal variability of PM(2.5) (PM with aerodynamic diameter < 2.5 microm) components in the United States; our objective is to identify components for a...

OBJECTIVE Open chest management (OCM) after cardiac surgery is a therapeutic option in the treatment of the severely impaired heart. The aim of this study was the evaluation of the incidence, survival and predictors of poor outcome for OCM with delayed sternal closure (DSC), particularly with regard to parameters to determine the time of closure. METHODS Prolonged open chest was used in 212 o...

Osseocalcineus metaplasia (OCM) of the tracheal cartilages is well known, but no exact data are available relating it to age and sex. To resolve this problem we analysed tracheal teleradiograms of 99 female (age: 0.4-92; x = 59.98 +/- +/- 22.75 years) and 110 male patients (age: 0-83; x = 53.53 +/- 19.95 years). As the first step we estimated the percentage of trachea that had complete lesions,...

Maximum Cross Correlation (MCC) technique have been used to derive coastal currents from sequential OCM derived suspended sediment concentration (SSC) maps and the MCC currents are integrated with the Ocean surface current analysis-Real time (OSCAR) ocean currents along the coastal regions of the Southern India. OSCAR currents are mainly depended on the oceanographic measurements from the satel...

BACKGROUND Population-based studies have estimated health risks of short-term exposure to fine particles using mass of PM(2.5) (particulate matter <or= 2.5 microm in aerodynamic diameter) as the indicator. Evidence regarding the toxicity of the chemical components of the PM(2.5) mixture is limited. OBJECTIVE In this study we investigated the association between hospital admission for cardiova...

Selective coupling of methyl radicals to produce C 2 species (C H 4 and 6 ) is a key challenge for oxidative methane (OCM). In traditional OCM reaction systems, homogeneous transformation in O -containing gases are uncontrollable, resulting limited selectivity yield. Herein, we demonstrate that generated by La 3 at low temperature can selectively couple on the surface 5 wt% Na WO /SiO . The con...

The production of volatile compounds in naturally fermented green table olives from Manzanilla cultivar was investigated. A total 62 were detected after 24 weeks fermentation. To clarify the contribution yeasts to formation these compounds, such microorganisms isolated corresponding fermenting brines. Five major yeast strains identified: Nakazawaea molendinolei NC168.1, Zygotorulaspora mrakii N...
