Desertification process has always been led to destruction of vegetation cover and soil and water resources that can occur in different climatic conditions, the intensity of which depends on the natural conditions of the region. Due to the increase in destruction of vegetation as one of the most important consequences of desertification, monitoring the changes and assessment of their trends are...
Background: Osteoporosis is a chronic disease and adherence can fluctuate over time. Therefore, longer observation is necessary to investigate the stability of patients' adherence. The study aim was to compare the overall adherence (OA) to supplementation with the fixed combination of calcium and vitamin D (Ca/D) in postmenopausal women at baseline and after 1 year, and to evaluate the fluctuat...
effects of short terms starvation periods on body composition of siberian sturgeon (acipenser baeri)
fish may experience periods of food deprivation or starvation in nature (such as seasonal migration and reproduction) and under culture conditions (unpredictable stress such as transporting and sorting). with respect to vital role of starvation periods on body composition, the current study was carried out in autumn 2010 at international sturgeon research institute. after adaptation for one mon...
The Standardized Precipitation Index (SPI) is the most common index for drought monitoring. Although the calculation of this index is usually done by using the gamma distribution fitting of precipitation data, studies have shown that for accurate monitoring of drought, the optimal distribution of precipitation in each month should be determined. On the other hand, in non-stationary time series,...
the conventional method towards deriving schedule for a fleet of ships to minimize cost alone has the short-coming of not addressing the problem of operation revenue losses associated with delays during maintenance at ships dockyards. in this paper, a preventive maintenance schedule for a fleet of ships that incorporates op-portunity cost is presented. the idea is to assign a penalty cost to al...
Spatio-temporal variability of wet and dry spells can be controlled by climate variability within a watershed and will affect availability of water resources and management plans. The application of the wet-dry spell analysis is presented for seven synoptic stations in the western part of Iran (Kurdistan Province). Numbers of consecutive months with standardized amount greater or less than the ...

The use of polymer nanocomposites is ubiquitous in every industry. high corrosion resistance and chemical durability CNT/Epoxy make them suitable for plants, oil industries, hydrogen storage. However, unexpected failures have been reported chemicals that unavoidably penetrate, provoking deterioration degradation the composite constituents. Conventional methods are impractical evaluating structu...
