Land suitability analysis is a prerequisite to achieving optimum utilization of the available land resources. Lack of knowledge on best combination of factors that suit production of rice has contributed to the low production. The aim of this study was to develop a suitability map for rice crop based on physical and climatic factors of production using a Multi-Criteria Evaluation (MCE) & GIS ap...
results in this study, a significant relation was established between the three areas or domains of learning: 1) knowledge domain (learning the theoretical basis of necessity-based training); 2) motivational domain (how to motivate collection, classification, etc. and 3) the technical domain (how trauma experts and specialists can recognize and classify needs practically. our findings suggest t...
Phytoplankton-bacteria interactions drive the surface ocean sulfur cycle and local climatic processes through the production and exchange of a key compound: dimethylsulfoniopropionate (DMSP). Despite their large-scale implications, these interactions remain unquantified at the cellular-scale. Here we use secondary-ion mass spectrometry to provide the first visualization of DMSP at sub-cellular ...
Several safety devices have filled in the vacuous spaces in commercial airplanes which once did not possess such sophisticated mechanisms. Commercial airplanes have copious amount of instruments and electrical circuits to provide a proper control system inside the plane. A noteworthy invention in the early 80’s is the oxygen masks provided for every passenger during a plane crash or if the airp...
. This study covers inquisitive approach to develop an Artificial Neural Network (ANN) model to foresee sugarcane production. The various input data set comprises the agro-climatic and socio-economic factors influencing sugarcane production whereas the output is real sugarcane output. Different forecasting techniques have been deployed on the concept of fuzzy time series data, whereas precision...
The aim of this research is the study of the climate change impacts on the seasonal and annual reference evapotranspiration time scales in some selected stations located in the West of Iran. To this purpose, four stations including Sanandaj, Saghez, Khorramabad and Kermanshah synoptic stations with enough long-term data were selected and the climate change impact on the reference evapotranspira...
We simulate the effect of climate change on water requirements of cold seasonwheat in various climatic zones of Iran. The research considers both observedclimate (temperature and precipitation) changes during recent decades (1960-2009)based on instrumental records and projected future changes to 2100 based on theMAGICC/SCENGEN 5.3 compound model. 20 General Circulation models are usedbased on a...
This work studies linear elliptic problems under uncertainty. The major emphasis is on the deterministic treatment of such uncertainty. In particular, this work uses the Worst Scenario approach for the characterization of uncertainty on functional outputs (quantities of physical interest). Assuming that the input data belong to a given functional set, eventually infinitely dimensional, we propo...
the main objective of this paper is to study climate changes and fluctuations in the four synoptic stations in sistan and baluchistan province in the past few years and to analyze statistically and simulate and forecast for the next years (2040-2009). this study used data from the outputs of general circulation climate model echo-g with a1 scenario that are now used at the university of hamburg...
Climate and land use changes are key drivers of current biodiversity trends, but interactions between these drivers are poorly modeled, even though they could amplify or mitigate negative impacts of climate change. Here, we attempt to predict the impacts of different agricultural change scenarios on common breeding birds within farmland included in the potential future climatic suitable areas f...
