In the rangelands of Iran, the lack of appropriate grazing management is one of the major problems ultimately leading to untimely and excessive grazing intensity of forage. Accordingly, most of the rangelands show a retrogression trend and poor conditions. In forage species, phenological stage is one of the most important criteria for range management. Bromus tomentellus species is an ...

introduction long-term climate records are valuable for environmental planning, and tree rings allow records to extend to the time before the establishment of weather stations. for a better understanding of the past climate fluctuation and to mitigate the effect of climate fluctuation, dendroclimatic reconstructions have been applied in many parts of the world. inter annual variations of climat...

Travel demand is well announced as a crucial component of transportation planning. This paper aims to develop a direct demand model, denoting a more acceptable abstraction of reality, for intercity passengers in daily work and leisure trips in Tehran province. The model utilizes combined estimation across the data source, collected in 2011, of travelers originating from ...

Tc-99m MIBI has recently been used in the functional imaging of various tumors. This prospective study was performed to evaluate the role of Tc-99m MIBI imaging at the time of the initial staging, assessment of treatment response, follow-up studies and survaillance in Hodgkin’s and non-Hodgkin’s Iymphoma. 25 patients (14 with Hodgkin’s and 11 with non-Hodgkin’s Iymphoma) underwent 32 stud...

Unfortunately, the presence of anxiety symptoms alone often does not serve as a sufficient incentive for a person with an anxiety disorder to seek help.

Another study reported the time span from onset of symptoms, at age 14.5 years, to ...

Global change in land water storage and its effect on sea level is estimated over a 7-year time span (August 2002 to July 2009) using space gravimetry data from GRACE. The 33 World largest river basins are considered. We focus on the year-to-year variability and construct a total land water storage time series that we further express in equivalent sea level time series. The short-term trend in ...
