Conduction characteristics of amorphous InGaZnO thin-film transistors were investigated by applying constant drain current with gate bias (V GS) modulation. Constant drain current in the off-current (I off) level from the transfer characteristic was applied to the drain electrode and the measured drain voltage with the gate bias sweep. The normalized channel conductance (G d) characteristics we...
Purpose: A prospective, randomized trial was performed to determine if intra-abdominal drainage catheters are necessary after elective liver resection.
Use of patient-specific drain-phase parameters has previously been suggested to improve peritoneal dialysis (PD) adequacy. Improving management of the drain period may also help to minimize intraperitoneal volume (IPV). A typical gravity-based drain profile consists of a relatively constant initial fast-flow period, followed by a transition period and a decaying slow-flow period. That profile w...
Submit Manuscript | http://medcraveonline.com position of the drain across the heart (Figure 1). Bed side echocardiogram showed the drain traversing the left ventricle (Figure 2). Bubble study through the chest drain showed contrast bubbles inside the left ventricle confirming position of the drain and perforation of the left ventricle (Figure 3). The drain was kept in situ. She was taken to th...
Increased chemical compounds in soil are the most important results of irrigation with domestic wastewater and treated effluents which contain some nutrients such as phosphorous (P). This process could increase the soil fertility, leading to the decrease of chemical nutrient consumption and consequently the cost of agricultural production. A research project was carried out in Tehran region for...
Life in central Iran depends on the Zayandehrood river, making the preservation of its quality important. Salinization and pollution of the flow as a result of different organic and inorganic pollutants create serious threats to the environment and to the agricultural activities in the region. Although the role of the main drains discharged into the Zayandehrood in changing its quality is well ...
