Evapotranspiration (ET) surface barriers store infiltrated precipitation during the recharge period and release stored water to atmosphere via ET. The primary purpose of a barrier is reduce or eliminate drainage underlying waste zone. objective this study analyze spatial temporal dynamics soil moisture within an ET based on observed simulated data. This characterizes movement processes using co...

Abstract The purpose of the study is to substantiate parameters deep-loader mole-drainage gun. A diagram a gun given. main working parts mole drainage tool are deep loader, knife, rope and drainer. Analytical dependences obtained for determining traction resistance Theoretical studies have established that high-quality loosening soil with minimal resistance, height digger should be 90 cm, width...

Based on the ICD (Individual channel Design) approach, the design of a multivariable digital submarine depth control system is presented. The model of the submarine is the standard 80 meters British submarine. As expected, the frequency rate of sampling introduces limitations to achieve the required responses. Furthermore, the discrete model presents zeros close to imaginary axis resulting in a...

Palliative drainage is the main treatment option for inoperable hilar cholangiocarcinoma to improve symptoms, which include cholangitis, pruritus, high-grade jaundice, and abdominal pain. Although there is no consensus on the optimal method for biliary drainage due to the paucity of large-scale randomized control studies, several important aspects of any optimal method have been studied. In thi...

Increasing incidence of pleural infection has been reported worldwide in recent decades. The pathogens responsible for pleural infection are changing and differ from those in community acquired pneumonia. The main treatments for pleural infection are antibiotics and drainage of infected pleural fluid. The efficacy of intrapleural fibrinolytics remains unclear, although a recent randomized contr...

OBJECTIVE To study the effect of subglottic secretions drainage on the incidence of ventilator-associated pneumonia (VAP) in patients receiving mechanical ventilation. DESIGN A randomized clinical trial. SETTING A 12-bed general ICU. PATIENTS One hundred fifty patients with an expected duration of mechanical ventilation > 72 h were enrolled in the study. INTERVENTION Patients were rando...

ABSTRACT We estimated the potential groundwater recharge (Rpot) of a drywell that receives, temporarily stores, and infiltrates direct surface runoff from contribution area (180.5 m2) comprising roof cemented floor. The Rpot for traditional rainwater management similar but covered with grass was also comparison. Our methodology involved use water budget equation, monitoring rainfall soil conten...

This research investigates the changes of soil properties in Dasht-e Abbas plain due to the Karkheh water transfer to this plain. In thisstudy, the maps of groundwater level changes before and after the utilization of irrigation system were prepared. Furthermore, toinvestigate the changes of soil characteristics, soil samples were collected from various project implantations and control areas a...

An in-depth analysis of the kinetics collision between freely rising oil droplets in water range Re = 4.64–463.3 was carried out to understand physical mechanism and detailed interaction wall. The results show that when with ≥ 27.8 hit wall vertically at terminal velocities, a “dimple-like” film is formed near wall, which significantly affects pressure distribution within film, oil–water interf...

Electrophotographic printers are required to provide photograph quality printing with the rapid implementation of color in an office environment and meet the needs for POD*1). The printing quality of conventional color electrophotographic printers is no longer capable of adequately satisfying the needs of customers. Furthermore, printing systems with a high resolution are used in the pre-press ...
