Under different climatic conditions of Iran, the evaluation of evapotranspiration (ETo) models sensitivity to meteorological parameters, prior to introducing the superior performance model, seems quite necessary. Using a 35-year (1971-2005) climatological observations in Hamedan, this study compares the sensitivity of different commonly used evapotranspiration models to different meteorological...
The aim of this study was to investigate the role of attachment styles, family cohesion, and perceived gender discrimination in predicting psychological hardiness in women with the reverse age of marriage. This research was descriptive and correlational. The statistical population of this study was women with the reverse age of marriage who referred to family counseling centers affiliated with ...
Quantitative evaluation of evapotranspiration on a regional scale is necessary for water resources management, crop production and environmental assessments in irrigated lands. In this study, in order to estimate ETo and because of few synoptic stations and also little recorded meteorological data in North Khorasan Province, Iran, with arid and semi-arid climate, 7 stations from neighboring pro...

Al -e- Muhtaj were one of the local rulers of Chaghanian region in upper part of the Oxus (Amu Darya) that had autonomy concurrent with period of Amir Ismaʽil Samani (279-295 AH) in their dominated area, i.e. parts of Khorasan and Rey. This local dynasty as puppet of Samanids, had effective role in political and military power of that state. Honesty and courage of emirs of this clan, including...
Background and aim: Medical methods of cancer treatment affect patients` reproductive health that is under treatment. Of course it is possible to solve patients` fertility problems by using fertility preservation methods. Our goal was to examine responsibility of informing oncologists from the method of fertility preservation for cancerous patients. Method: In this paper, using the method of s...
The proposed method for calculation of potential evapotranspiration is Penman-Monteith FAO method, but there are other methods that require less meteorological data but estimates close to the FAO Penman-Monteith method in different climatic conditions. Performance evaluation of these methods on the same basis is prerequisite for selecting an alternative approach in accordance with available da...
detention rockfill dams are an easy and common tool for flood control. due to their coarse pores, the flow in void spaces is turbulent and non-darcy. different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. the present research is aimed at gaining a better understanding of the differ-ence among these relationships and the sou...
for the purposed water resources management, irrigation scheduling, water usage optimization and gaining maximum yield two step fao method was applied to determine the water requirement (evapotranspiration) of sugar beet. in this paper reference evapotranspiration were computed from recorded meteorological data at 38 weather stations using the hargreaves-samani method; and then through applyin...
T he past 3 months have seen the publication of a series of studies examining the inherited genetic underpinnings of common diseases such as prostate cancer, breast cancer, diabetes, and in this issue of the Journal, coronary artery disease (reported by Samani et al., pages 443–453). These genomewide association studies have been able to examine interpatient differences in inherited genetic var...
