Surface sediment samples were collected from different streams of Awetu Watershed in southwestern Ethiopia. Sediment analyzed for As, Cd, Cr, Pb, and Hg levels using inductively coupled plasma optical emission spectrometry. The heavy metal concentration ranged 183.60 to 1,102.80 mg/kg As (mean 623.32 ± 291.65 mg/kg), 4.40–303.20 Cd (151.09 111.5 149.20–807.20 Cr (375 212.03 485.60–3,748.80 Pb (...

palmprint recognition is a new biometrics system based on physiological characteristics of the palmprint, which includes rich, stable, and unique features such as lines, points, and texture. texture is one of the most important features extracted from low resolution images. in this paper, a new local descriptor, local composition derivative pattern (lcdp) is proposed to extract smartly stronger...

Personal exposures to 15 volatile organic compounds (VOC) and 16 polycyclic aromatic hydrocarbons (PAH) of 100 adult nonsmokers living in three UK areas, namely London, West Midlands, and rural South Wales, were measured using an actively pumped sampler carried around by the volunteers for 5/1 (VOC/PAH) consecutive 24-h periods, following their normal lifestyle. Results from personal exposure m...

Previous analyses of car theft data from the British Crime Survey (BCS) have suggested that usual place of parking (e.g., in the street or in a garage) is related to risk of theft, even allowing for the fact that parking options vary with otherfactors (such as living in an inner city) that themselves affect risk. However, theft risks have been assessed for people usually parking in different lo...

BACKGROUND Urban bus operators are an occupational group with high rates of overweight and obesity. Understanding methods bus operators use for weight control may be important; there may be increased risk for these workers to engage in less healthy weight management behaviours due to stressful working conditions. AIMS To examine the prevalence of unhealthy and healthy weight control behaviour...

the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...

Mechanical mining is a widely used method of separating materials from the face to obtain useful mineral (e.g., coal, metal ores, salts, and diamonds), make underground workings mine galleries, tunnels, garages), level roads, shape slopes, or dig ditches. applied in branch, tunnelling, road, construction industries. Depending on mechanical properties rocks, most frequently described by uniaxial...
