Impact of drip and overhead sprinkler irrigation on the persistence of attenuated Escherichia coli O157:H7 in the lettuce phyllosphere was investigated using a split-plot design in four field trials conducted in the Salinas Valley, California, between summer 2007 and fall 2009. Rifampicin-resistant attenuated E. coli O157:H7 ATCC 700728 (BLS1) was inoculated onto the soil beds after seeding wit...

ABSTRACT DMulching contributes to the maintenance of soil moisture at reasonable levels for crop growth. It influences water demand and irrigation time. The aim this study was estimate evapotranspiration root uptake by ‘BRS Princesa’ banana cultivar through a simple approach using some components balance within zone in bare mulched irrigated drip micro sprinkler systems. experimental design com...

This paper discusses the experimental set-up and procedures for the seismic testing and evaluation of a sprinkler system in hospital model. Concrete compression tests are ran to ensure compliance with ACI 355.2 anchor testing qualifications. Maximum shear strength of the anchor is found to include within the piping system model. Frame and piping system within the model is tested under input mot...

Mobile drip irrigation (MDI) technology adapts driplines to the drop hoses of moving sprinkler systems to apply water as the drip lines are pulled across the field. There is interest in this technology among farmers in the Texas High Plains region to help sustain irrigated agriculture. However, information on the performance of this system and its benefits relative to common sprinkler applicati...

This study was carried out to investigate the effect of treated wastewater on soil chemical and physical properties. Field experiment was conducted in Borkhar region in Isfahan province in central Iran with two water treatments of wastewater and groundwater under sprinkler and surface irrigation systems for three crops of sugar beet, corn and sunflower. Soil samples were collected to 120 cm dep...

Buildings with atrium can be found everywhere in big cities among which Hong Kong is one of the examples. The evolution of this building type should be traced back to explore the reason why it has been a popular design throughout these years. It was found originated about two hundred years ago, with changes in terms of configurations and functions occurred. After centuries of development, benef...

The existing irrigation system namely drip and sprinkler adds cost to production. So, an alternate low-cost (rain hose irrigation) was compared with other systems. study proposed find out the optimum soil moisture by selecting a proper that supports management, enhanced productivity, high water use efficiency, also involves less on treatment comprises different methods of (drip, sprinkler, rain...

An improved method for making a decision on choosing the best self-propelled sprayer from alternative options is proposed. It refers to new developments in various fields of environmental monitoring and analysis field sprinklers, but which substantiate studied factors characterizing each unit. The are taken with real values calculated parameters, desirability function weighty coefficients devel...
