The most important factor affecting the yield of agricultural crops is formation an optimal water regime in active soil layer. One main methods carrying out such works sprinkling, since it closest to process natural precipitation. At same time, existing sprinklers do not provide watering lands that meets agro-technological requirements due design features and specifics landscape on which they a...

In order to ensure the optimal state of recovered molding sand inside a foundry, it is necessary avoid temperature peaks and humidity conditions prior reusing sand. Sand that too hot or without moisture can cause production delays due long mixing process, excessive consumption raw materials, poor agglutination. To stable temperature, many foundries choose incorporate coolers into their however,...

Abstract The interest in promoting food and water security through development projects has led to the need evaluate impact of these projects. This study evaluates from transitioning a modern irrigation technology. Deciding adopt or not an alternative technology (sprinklers) is necessarily random determination. Therefore, selection bias can be present this lead biased estimates. In study, we ap...

Re-suspension of iron ore dust presents a constant hazard in the working environment within steel production plants. Herein, optimal operating parameters for maximum suppression efficiencies through water mist generator and conventional sprinkler particulate matter (PM) originating from an pile measuring about 2 m height with stacking angle 30° are investigated. The effects including wind veloc...

The quality of cotton fiber is a fundamental criterion for determining the commercial value product, being influenced by conditions cultivation. study aimed to evaluate irrigated and non-irrigated cultivation systems management silicon fertilization on characteristics. experiment was carried out in field Selvíria-MS, 2017/2018 agricultural crop. It adopted randomized block design, 2x6 factorial...

This study presents a novel hybrid solar chimney power plant (HSCPP) design. The HSCPP preserves the typical (SCPP), with an additional seawater pool at base and water sprinklers top. new design configuration offers opportunity to run system during daytime as traditional SCPP downdraft cooling tower night. performance of was analyzed in 16 cities Kingdom Saudi Arabia (KSA) that span entire geog...

the variety of sprinkler devices available for the center pivot and linear irrigation systems has been increased dramatically in recent years. in the current study, via conducting some indoor experiments, one type of fixed pad spray sprinkler (d3000) and two types of moving pad spray sprinklers (r3000 and s3000) with various configurations (working pressure, nozzle size and type of deflector pa...

The radial water distribution and irrigation performance of an agricultural sprinkler with plastic nozzles were analysed. Twenty-six tests with an isolated sprinkler corresponding to different combinations of three working pressure (p, 200, 300 and 400 kPa) and three nozzle diameters of the main nozzle (4.0, 4.5 and 5.0 mm) were performed to evaluate the radial water distribution curves, All th...

A precision control system that enables a center pivot irrigation system (CP) to precisely supply water in optimal rates relative to the needs of individual areas within fields was developed through a collaboration between the Farmscan group (Perth, Western Australia) and the University of Georgia Precision Farming team at the National Environmentally Sound Production Agriculture Laboratory (NE...

Reducing emissions is essential for minimizing the impact of soil fumigation on the environment. Water application to the soil surface (or water seal) has been demonstrated to reduce 1,3-dichloropropene (1,3-D) emissions in soil column tests. This study determined the effectiveness of water application to reduce emissions of 1,3-D and chloropicrin (CP) in comparison to other surface seals under...
