$+" $!" Understanding the relationship between low frequency variations in large-scale $#" atmospheric circulation driven by the oceans and high latitude hydro-climatic variability $$" at regional scales is important to assess the projections of climate change in these regions, $%" and for designing measures for climate change adaptation. Here we analyze the recent $&" (1978-2004) variability i...
abstract the present research is prepared to study the culture of tea consuming among iranian. the case group which was statistically used for this study was people of lahijan , about four hundred wich were chosen according to their age , gender , education and occupation , randomly selected to fill the questionnaire . then the data collected through the questionnaire was analyzed according ...
Flower buds of peach, apricot, and sweet cherry are killed by low temperatures during winter and spring. Frost protection measures used commonly in the spring are applied to freeze protection during the winter in the Yakima Valley of Washington. Critical temperatures change rapidly during winter. To succeed, winter freeze protection requires adequate inversions, equipment that operates at tempe...
Primary chronic forms of copper poisoning have been reported to occur in goats around the copper industries in Kerman province. The survey was carried out from autumn 2015 to the end of summer 2016, in Kerman province, Iran. Based on clinical signs, confirmed by necropsy and copper concentration of serum and different tissues, ten live chronic copper poisoned (CCP) goats were used in the study ...
"Technical Report" The quality of coastal water resources at the downstream of watersheds is decreasing mainly due to different anthropogenic activities. In this research, temporal variations of groundwater quality were investigated in a 25000 ha coastal area in Mazandaran province. Groundwater samples were taken from 37 observation wells in the region before (winter 2009), during (spring ...
Temporal variation in the abundance of the encephalitis virus vector mosquito, Culex tarsalis Coquillet, was linked significantly with coincident and antecedent measures of regional climate, including temperature, precipitation, snow pack, and the El Niño/Southern Oscillation anomaly. Although variable among traps, historical records that spanned two to five decades revealed climate influences ...
Previous population dynamics data, generated for Amblyomma parvum Aragão and Amblyomma cajennense (Fabricius) in Argentina and southeastern Brazil, have indicated that these ticks complete 1 generation per year, with larvae predominating in autumn, nymphs in winter, and mostly adults during spring and summer. The present study reports population dynamics data for free-living Amblyomma spp. tick...
This study analyzed hourly mass concentration observations of PM2.5 (particulate matters with diameter less than 2.5 μm) at 512 stations in China from December 2013 to May 2015. We found that the mean concentrations of PM2.5 during the winter and spring of 2015 Dec. 2014 to Feb. 2015 and Mar. 2015 to May 2015) decreased by 20% and 14% compared to the previous year, respectively. Hazardous air-q...
A year-round grazing system for springand fall-calving cows was developed to compare animal production and performance, hay production and feeding, winter forage composition changes, and summer pasture yield and nutrient composition to that from a conventional, or minimal land system. Systems compared forage from smooth bromegrass-orchardgrass-birdsfoot trefoil pastures for both systems in the ...
A field trial was conducted on 5 farms to determine the effect of feeding distillers dried grains (DDGS) on milk production in the southern dairy region of Chile. The trial was repeated on each farm during winter (July and August; primarily silage-based rations) and spring (November and December; pasture-based rations). Only for one farm could the treatments be applied concurrently by feeding d...
