The objective of this study was to evaluate non-genetic factors affecting longevity and survival of Guilan sheep from birth to yearling. Longevity and survival records of 41037 lambs born from 496 rams and 10256 ewes of Guilan sheep were analyzed using linear and Weibull models. Results indicated that the overall mean of longevity was 1260.84 days. The fixed effects of flock, dam age, sex, year...
On November 12, 2017, at 18:18 UTC, a major earthquake with moment magnitude Mw7.3 struck the Kermanshah province of Iran, causing extended damage and casualties. Thus, we explore seismicity preceding this earthquake, with the aim to understand whether the information from past events could provide some insights about the occurrence of this and other future large earthquakes. Taking into accou...
the objective of this paper is to determine the drift demand hazard curves of steel moment-resisting frames with different number of stories in territory of tehran this is done through the combination of the results obtained from probabilistic seismic hazard analysis and the demand estimated through the best probabilistic seismic demand models. to select the best demand model, in this paper, a ...
