Efficient Solid waste utilization is a challenging task. In rural areas organic wastes like cattle waste is available in abundant, which is not utilized in the valuable forms and in urban areas it is disposed off in an improper manner. In this study biogas primarily from cattle waste was generated by using a fabricated anaerobic biogas digester. The methane is easily separated from biogas by re...

Ambient wintertime background urban aerosol in Cork city, Ireland, was characterized using aerosol mass spectrometry. During the three-week measurement study in 2009, 93 % of the ca. 1 350 000 single particles characterized by an Aerosol Time-of-Flight Mass Spectrometer (TSI ATOFMS) were classified into five organic-rich particle types, internally mixed to different proportions with elemental c...

Prior research by Pitt (1987) examined runoff losses from paved and roofed surfaces in urban areas and showed significant losses at these surfaces during the small and moderate sized events of most interest for water quality evaluations. However, Pitt and Durrans (1995) also examined runoff and pavement seepage on highway pavements and found that very little surface runoff entered typical highw...

the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

A new technique has been developed to deconvolve and quantify the mass concentrations of hydrocarbon-like and oxygenated organic aerosols (HOA and OOA) using highly time-resolved organic mass spectra obtained with an Aerodyne Aerosol Mass Spectrometer (AMS). This technique involves a series of multivariate linear regressions that use mass-to-charge ratios (m/z’s) 57 (mostly C4H9) and 44 (mostly...

adverse lifestyle changes like rapid change in dietary habits coupled with decreased physical activity and increasing rates of alcohol and tobacco consumption can increase coronary artery disease risk factors and its mortality even higher than the rates predicted. to evaluate the role of adverse lifestyle changes factors in the causation of cad, a hospital based case-control study was conducted...
