the purpose of this research is to analyze heat waves characteristics in the warm period of the year as a climatic hazard in iran. in this study, the daily maximum temperature is taken at 44 synoptic stations during the period 1981-2010. these temperature values were used to extract the intensity, frequency and duration of heat waves using percentile thresholds of 90, 95, and 98. the results sh...

The present study was undertaken to assess the growth in fertilizer consumption and instability by using data for period 1990-91 2019-20 analyses exponential model. periods of were divided into four sub-periods viz. Period-1 (1990-91 1999-00), Period-II (2000-01 2009-10), Period-III (2010-11 2019-20), Overall 2019-20) meaningful elucidation results. NPK Haryana across divisions, during period-I...

6 [1] This study examined daily streamflow response over up to four decades in northwest 7 conifer forest and eastern deciduous forest sites in the United States. We used novel 8 methods to analyze daily observations of climate and streamflow spanning more than 9 900 basin years of record at 14 treated/control basin pairs where forest removal and 10 regrowth experiments were underway in the per...

Animal daily routines represent a compromise between maximizing foraging success and optimizing physiological performance, while minimizing the risk of predation. For ectothermic predators, ambient temperature may also influence daily routines through its effects on physiological performance. Temperatures can fluctuate significantly over the diel cycle and ectotherms may synchronize behaviour t...

an agroecological zones (aez) map is an essential tool for agricultural planning. by integrating the key components of the agricultural environments, it offers a bird's-eye view of internal diversity, agricultural potential and constraints that decision-makers find easier to understand than a pile of single-theme maps. in this study, aez map of the karkheh river basin has been prepared usi...

Native glycogen was isolated from Tetrahymena pyriformis (HSM) by isopycnic centrifugation in cesium chloride density gradients. A density of 1.62 to 1.65 was isopycnic for glycogen. Most of the banded glycogen existed as 35 to 40 mmicro particles which had a sedimentation coefficient of 214. These particles were composed of aggregates of 2 to 3 mmicro spherical particles. Extraction of glycoge...

Growth of largemouth bass, Micropterus salmoides, was tested under constant (1 5" C, 29" C) and cyclic ( I 8 h at 15" C, 6 h at 29" C) temperature conditions. Six groups of 10 fish each were tested; one group under each constant condition, and four groups in the thermocycles. The four latter groups differed in the timing of their feeding; one group each was fed at the start and middle of the wa...

in the second half of the 2nd/8th century, the ismā‘īlī sect, who believed in the imamate of ismā‘īl, the second son of imam ja‘far al-ṣādiq (a.s.), was formed. the ismā‘īlīs brought up specific views concerning imamate. from their point of view, the world of being can not survive a moment without the existence of an imam and that mankind is always in need of a teacher, leader, and infallible i...
