Model to design drip hose lateral line using two spacing between emitters
(2012-12-01)
The use of non-pressure compensating drip hose in horticultural and annual cycle fruits is growing in Brazil. In this case, the challenge for designers is getting longer lateral lines with high values of uniformity. The ...
Model to increase the lateral line length of drip irrigation systems
(2012-12-01)
Non-pressure compensating drip hose is widely used for irrigation of vegetables and orchards. One limitation is that the lateral line length must be short to maintain uniformity due to head loss and slope. Any procedure ...
Mathematical models to optimize lateral line length using two spacing between drippers
(2014-01-01)
In drip irrigation systems, longer lateral lines can provide cost reduction, but it is limited by the required irrigation uniformity. Non-pressure compensating drip hose is widely used for vegetables and orchards irrigation ...
Design of microirrigation systems in sloping lands using linear programming
(2000-12-01)
When the area to be irrigated has a high slope gradient in the manifold line direction, an option is to use a tapered pipeline to economize on pipe costs and to keep the pressure head variations within desired limits. The ...
Modification of polyethylene terephthalate by atmospheric pressure dielectric barrier discharge (DBD) in view of improving the polymer wetting properties
(Iop Publishing Ltd, 2012-01-01)
Surface treatment of polymers by discharge plasmas has increasingly found industrial applications due to its capability of modifying uniformly the surface without changing the material bulk properties. This work deals with ...
Treatment of polycarbonate by dielectric barrier discharge (DBD) at atmospheric pressure
(Iop Publishing Ltd, 2014-01-01)
Generally most plastic materials are intrinsically hydrophobic, low surface energy materials, and thus do not adhere well to other substances. Surface treatment of polymers by discharge plasmas is of great and increasing ...

Morphology and properties of (Ba, Sr, Ca) titanates synthesized by microwave-assisted hydrothermal method
(2011)
Ba1-xCaxTiO3, Ba1-xSrxTiO3 and Sr1-xCaxTiO3 (x = 0, 0.25, 0.50, 0.75 and 1) nanoparticles were synthesized using the microwave-assisted hydrothermal method. Samples were prepared for 40 minutes at 140°C under a pressure ...
Optimization of the Electrical Performance of Metal Oxide Thin-film Transistors by varying Spray Deposition Parameters
(2018-01-01)
Metal oxides like zinc oxide (ZnO) are promising materials for the active layer of thin-film transistors (TFTs) used in the drive circuit of next-generation large-area active matrix displays due to their high electronic ...
Experimental aspects of partially premixed pulsating combustion
(2005-12-27)
The pulsating combustion process has won interest in current research due to indications that its application in energy generation can offer several advantages, such as: fuel economy, reduced pollutants formation, increased ...
