Monitoring of diamondback moth (Plutella xylostella L) population on cabbage and Chinese cabbage over the past eight years has indicated that heavy rains from June to September limit the population of the insect. Therefore, during the dry period when diamondback moth is a serious pest, water was applied by sprinkler system placed 1.5 m over the cabbage crop rather than by traditional furrow irr...

The present study aimed at the development of the water deficit coefficient as a function of the Christiansen uniformity coefficient and relationship between the applied water depth and that required by a given crop, taking into account that the water distribution by the sprinkler follows a normal distribution. Another objective was to compare the experimental results to those obtained through ...

background: it is estimated that major depression disorders constitute 8.2% of years lived with disability (ylds) globally. the repetitive transcranial magnetic stimulation (rtms) and electroconvulsive therapy (ect) are two relative common interventions to treat major depressive disorders, especially for treatment resistant depression. in this study the cost- effectiveness and cost-utility of r...

introduction: designing and management of sprinkler irrigation systems depend on the situation and location of its implementation and often rely on professional and long-term tests (9). having a good irrigation system depends on knowledge of the relationship between soil, water, plants, irrigation scheduling, the required amount of irrigation water to the water-holding capacity of soil, climate...

Many semiarid and arid soils are prone to irrigation-induced erosion. Polyacrylamide (PAM) greatly reduces erosion from furrow irrigation. We hypothesized that PAM applied via sprinklers will provide erosion control and benefit water infiltration and aggregate stability. Screened (6.4 mm) Rad silt loam (coarse silty, mixed, superactive mesic Durinodic Xeric Haplocambid) was placed in 1.5 by 1.2...
