in order to evaluate drought tolerance of some aegilops triuncialis ecotypes a factorial experiment based on a completely randomized design was conducted under non-stress and drought stress (irrigation until 50% of heading) condition in the greenhouse of mohaghegh ardabili university in 2012. drought tolerance and susceptibility indices for grain yield were calculated and principal component an...
fusarium head blight (fhb) is an important disease in wheat worldwide that reduces grain yield, quality as well as contaminates grains to the mycotoxins. thirty spring wheat genotypes including 28 bread wheat and two durum wheat genotypes were evaluated for fhb under a randomized complete block design with three replications. grain yield and its components were evaluated by using two environmen...
Prioritization of watershed basins includes classification of sub-basins on the basis of the existing conditions and erosion intensity, which ultimately leads to protective operations and watershed management in more significant and susceptible sub-basins. In this research, in order to prioritize Ghezel Owzan-Sefidrud sub-basins against sensitivity to erosion, linear and form-based morphometric...
CONTEXT Better methods for investigating sexual risk before the initiation of sexual intercourse are needed to support programming for younger adolescents, especially for abstinent adolescents who are susceptible to initiating intercourse. METHODS A sample of 854 adolescents in seventh or eighth grade who had never had sexual intercourse completed sexuality surveys in 2002 and 2004. A five-it...
The development of landslide susceptibility maps is of great importance due to rapid urbanization. The purpose of this study is to present a method to integrate the subjective weight with objective weight for regional landslide susceptibility mapping on the geographical information system (GIS) platform. The analytical hierarchy process (AHP), which is subjective, was employed to weight predict...
This paper presents the spatial susceptibility risk mapping of tuberculosis (TB) using a geographical information system (GIS) index model and satellite remote sensing (RS) imagery. GIS RS-based approach is proposed as an alternative method in identifying potentially high-risk areas Klang, Selangor. The level for selected socio-spatial factors map was classified into five-scale from 1, which no...
1- Introduction The gully erosion occurrence, due to the high rate of sediment production in the watershed, is one of the problems of natural resources management in the context of soil management and protection. It is known as an important signature of land degradation and forming as well as a source of sediment in a range of environments. Gully erosion often has severe environmental and econ...
Chlorine and sulfate toxicity in water and soils are the main factors limiting growth and yield of most plants. Tolerance and sensitive indexes related to Cl and SO4 in irrigation water and effect of nitrogen fertilizer on barley were evaluated in a completely randomized design with three replications, under greenhouse conditions. Quantity salinity tolerance and susceptibility indices such as M...
China is a country prone to geological disasters, especially in the northern mountainous areas of Tianshan Mountains Xinjiang, where surface vegetation sparse and rainfall concentrated, which landslides brings lot losses local people. Based on field investigation, this paper evaluates landslide susceptibility area Mountains. The frequency ratio method used calculate probability, index (LSI) for...
