Background & Aims of the Study: In developing countries, with increasing use of computer systems, millions of computer workers are at high risk of neck and shoulder pains. The aim of this study was to assess the relationships between work-related physical and psychosocial factors and persistent neck and shoulder pains among computer office workers. Materials & Methods : This longitudin...

Six songbird species were studied to determine how testis size varies in relation to latitude, using data from breeding areas at latitudes 7°N to 69°N. Three of the species (Carpodacus mexicanus, Vireo olivaceus, Geothylpis trichas) exhibited a significant positive relationship, one (Passerculus sandwichensis) a significant negative relationship, and two (Agelaius phoeniceus, Spizella passerina...

Groundwater is one of the most important water resources especially for irrigation in the east of Iran. So, it is important to note its water quality variation for deciding to manage it. To this end, the study were done to zone Birjand plain located at latitude between 32˚ 30’-33˚ 00’ N and longitude between 58˚ 45’-59˚ 41’ E. In order to achieve this goal, the required layers, Sodium adsorptio...

Changes of snow occurrence across the central and eastern United States under future warming for the late 21(st) century are investigated by applying an empirical hyperbolic tangent function to both observed and downscaled high spatial resolution (~12.5 km) daily temperature and precipitation, to compare the historical (1981-2000) and future (2081-2100) snow occurrence. The observed distributio...

The aim of the study was to evaluate the efficacy of aglepristone (10 mg/kg on days 1, 2 and 8) for the treatment of metritis or pyometra in bitches (n = 67) either alone for cases of metritis (n = 15), or in cases of pyometra (n = 52) with (n = 32) or without (n = 20) the addition of low doses (1 microg/kg) of cloprostenol for 5 days (days 3-7). Examinations performed on day 90, in addition to...

[1] We present a long-term study, from January 1996 to August 2012, of the latitude of the Heppner-Maynard Boundary (HMB) measured at midnight using the northern hemisphere Super Dual Auroral Radar Network (SuperDARN). The HMB represents the equatorward extent of ionospheric convection and is used in this study as a measure of the global magnetospheric dynamics. We find that the yearly distribu...

Primary productivity in the nutrient-poor subtropical ocean gyres depends on new nitrogen inputs from fixers that convert inert dinitrogen gas into bioavailable forms. Temperature and iron (Fe) availability constrain marine fixation, both are changing due to anthropogenic warming. We examined physiological responses of globally important fixer, Crocosphaera watsonii across its full thermal rang...
