The proportion of agricultural water consumption is continuously decreasing due to increased competition for resources by urban, industrial, and users. Drip irrigation more efficient in terms energy utilization. These considerations are critical view the ongoing struggle among various consumers scarcity. Some most criteria effective design maintenance drip systems shape size volume wet soil ben...

conclusions in conclusion, the suspension containing veegum 1%, sodium carboxy methyl cellulose 1%, glycerine 0.2%, sodium citrate 0.3% and sorbitol 20 % was chosen as the most physically stable formulation. results according to the results, glycerin (0.2%) and sodium citrate (0.3%) had the best effect on the suspension stability as wetting and flocculating agents, respectively. rheological pro...

OBJECTIVE To investigate the psychological problems associated with bedwetting and combined (day and night) wetting in children aged around 7(1/2) years. METHODS Participants were a cohort of over 8000 children enrolled in the population-based Avon Longitudinal Study of Parents and Children. Parents completed postal questionnaires assessing common childhood psychological problems, and childre...

Forty children with day and night wetting were compared with 46 with night wetting only to see if day wetting was then associated with particular clinical features. Interviews with mothers, questionnaries completed by teachers, physical investigations, and measurement of functional bladder capacities were used. Day wetting combined with bed wetting occurred equally in boys and girls and was ass...

In this study, the wetting behaviors of single droplet on a micro square-post patterned surface with different geometrical parameters are investigated theoretically and numerically. A theoretical model is proposed for the prediction of wetting transition from the Cassie to Wenzel regimes. In addition, due to the limitation of theoretical method, a numerical simulation is performed, which helps ...

We report simulation evidence that the structure of the first water layer next to the surface can strongly affect the contact angle of water droplets. Molecular dynamics simulations show that a small uniform strain (± 3%) applied to the lattice constant of a multilayer hydrophilic surface can introduce a marked change in the wetting tendency. In particular, when the lattice constant of a hydrop...

Amethodof calculation is introduced that allows the simulation of the time-dependent three-dimensional motion of liquid droplets on solid substrates for systems with finite equilibrium contact angles. The contact angle is a prescribed function of position on the substrate. An evolution equation is given, using the lubrication assumption, that includes viscous, capillary, and disjoining forces. ...
