Building a model to rapidly simulate the impact of typhoons on agriculture and to predict agricultural losses is crucial and great help for remedial measure and distributing subvention right after the disaster. The relationship between typhoon-related meteorological factors and agricultural losses was first evaluated, and the Pearson’s test was applied to find consequences of both landfall and ...

ABSTRACT This study presents a numerical and experimental comparison of two different types radial fans used in an agricultural fertilizer spreader at rotation 4000 rpm. The analysis was validated through experiments conducted on test bench using hot-wire anemometer for velocity measurements Pitot tube pressure readings. A simulation the carried out after validation mathematical models to evalu...

heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...

Flue gas desulfurization (FGD) by-products are created when coal is burned and SO2 is removed from the flue gases. These FGD by-products are often alkaline and contain many nutrients including S. Agricultural application of FGD by-products is encouraged but little information is available related to plant responses and environmental impacts concerning such use. Agricultural lime (ag-lime) and s...

Agricultural Entrepreneurship One of the areas of entrepreneurship is the acceptance of the risks of a production, service, and business unit related to agricultural activities.  The purpose of this study was to analyze the strengths, weaknesses, opportunities and threats of entrepreneurship development in the agricultural sector of Khuzestan province using AHP-SWOT integrated approach. The res...

Background and aim: Today, the use of scientometric methods to evaluate the scientific outputs of researchers in various fields has been highly regarded and the Hirsch index (h-index) is one of the most important scientometric indices due to the simultaneous measurement of quantity and quality of scientific outputs. Therefore, the aim of this study was to evaluate the status of Iranian agricult...

Signatories of the Kyoto Protocol are obliged to submit annual accounts of their anthropogenic greenhouse gas emissions, which include nitrous oxide (N(2)O). Emissions from the sectors industry (3.8 Gg), energy (14.4 Gg), agriculture (86.8 Gg), wastewater (4.4 Gg), land use, land-use change and forestry (2.1 Gg) can be calculated by multiplying activity data (i.e. amount of fertilizer applied, ...
