126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Records from 7 studies conducted during 1999 to 2005 were utilized to assess the effects of environmental factors on daily water intake (DWI) of finishing cattle. Data from unshaded feedlot pens (up to 24 pens utilized per study; 6 to 9 animals·pen(-1)) containing predominantly Angus crossbred cattle were obtained by dividing total water intake by the number of animals utilizing that waterer. E...
Seasonal asymmetry in the interannual variations in the daytime and nighttime climate in the Northern Hemisphere (NH) is well documented, but its consequences for vegetation activity remain poorly understood. Here, we investigate the interannual responses of vegetation activity to variations of seasonal mean daytime and nighttime climate in NH (>30 °N) during the past decades using remote sensi...
It is critical to understand how meteorological variables impact reference evapotranspiration (ETo) since have a different effect on ETo. This study examined the of ETo Korean Peninsula under complex climatic and geographic conditions in order changed over past 42 years. Different geographical were analyzed, including plains, mountains, coastal areas seasonal annual basis. was estimated using P...
The effect of cultivar and environmental variations their interaction on anthocyanin components strawberry were assessed for six cultivars grown in five locations from North to South Europe two different years. To evaluate the impact latitude- altitude-related factors, daily mean (Tmean), maximum (Tmax) minimum (Tmin) temperature global radiation accumulated 3, 5, 10 15 days before fruit sampli...
weather condition is one of the much effective factors in the principle of architecture and urbanization. so in this research long-term trend of effective climate elements in architecture of darab city including mean of minimum temperature, temperature mean, mean of maximum temperature, minimum relative humidity, maximum relative humidity, relative humidity mean, wind speed and sun hours in mon...
In this study, kriging method applied to mean daily temperature dataset of 663 synoptic and climatic stations from 1961 to 2004 in Iran. So a gridded database of mean daily temperature with 15*15 Km spatial resolution prepared. This database contains 15992 days and 7187 pixels. Based on this grid data extreme temperature database has been calculated using Normalized Temperature Deviation Index....
Increasing the temperature of the urban environment is one of the most important environmental problems in cities. The purpose of this research is to evaluate the importance of different tree types as a way to adjust temperature and then to propose cultivating temperature modifications in urban conditions. To do this, firstly, in each of the desired tree species (Sycamore, Siblings, Acacia, San...
