The improvement of irrigation systems in the Nile Delta is one of the most important attempts in Egypt to implement more effective irrigation technology by improving the existing irrigation networks. Demand delivery system in the existing irrigation network is using of mechanical gates structures to automatically divert water from one portion of an agricultural field to another in the desired a...
A field crop irrigation management decision-making system (CropIrri) was developed based on the soil water balance model, crop phenology model, root growth model, crop water production function, and irrigation management model. The irrigation plan is made through predicating of soil water content in root zone and daily crop water requirement using historical and forecasting weather data, measur...
and Introduction Abstract Pulsatile lavage is a high-pressure irrigation treatment commonly used in the debridement of wounds. The risk of exposure to bloodborne pathogens and contaminants using high-pressure irrigation has been well documented in the literature. Projectile droplets and aerosolized fine droplets may form and spread, potentially contaminating the treatment facility and infecting...
water balance components are difficult to measure in short intervals because their measurement is time consuming and costly. therefore, soil-water--plant models can be used for prediction of these components. in this study, to predict grain yield and evaluate water use efficiency, an agro-hydrological model, namely, swap was used. this study covered a 10-years period from 2000-2010. based on th...
A simulation model was developed to estimate the effect of deficit irrigation upon crop yield. The model was designed to provide relative yield estimates for numerous combinations of irrigation system, crop growth and irrigation management parameters. A daily soil moisture balance was used to predict evaporation and transpiration from which crop yields were estimated. Gross irrigation water req...
* Corresponding author. [email protected] Abstract – Previous studies have shown that irrigation can impact the near-surface climate, but none refer to the differences in the impacts of irrigation types such as flooding and spraying. In this study, we add a novel irrigation module to the recently released community land model 4.0 and simulate irrigation in two ways: first, by spraying water...
Maxillofacial fractures present unique airway problem to the anesthesiologist. Patients with LeFort III fractures are at great risk of requiring emergent airway control due to midface instability and oropharyngeal airway obstruction. We present a case where difficult intubation was managed with close cooperation between the anesthesiologist and the surgeon.
Introduction. This experimental study is to compare radiographs based on the penetration depth of the irrigant following three final irrigation techniques. Material and Method. A sample of sixty teeth with single roots were prepared with stainless steel K files followed by mechanized Ni-Ti files iRace® under irrigation with 2.5% sodium hypochlorite. Radiopaque solution was utilized to measure t...
A comparison of decision rules has been made for case studies of corn production using subsurface drip irrigation under three agricultural management practices (no irrigation, uniform irrigation, and variable rate irrigation). The uniform irrigation strategy appeared to perform the best than the other two management practices under different risk scenarios.
OBJECTIVE To compare intranasal distribution of saline solution delivered by three popular methods for nasal saline irrigation. STUDY DESIGN Prospective, controlled comparison. METHODS Eight healthy adult volunteers received nasal irrigation with 40 mL of isotonic, nonionic contrast material immediately before having coronal computed tomography to visualize distribution of solution in the p...
