Water transfers from agricultural to urban and environmental uses will likely become increasingly common worldwide. Many agricultural areas rely heavily on underlying groundwater aquifers. Out-of-basin surface water transfers will increase aquifer withdrawals while reducing recharge, thereby altering the evolution of the agricultural production/groundwater aquifer system over time. An empirical...

A measure of insulation film floating on the water surface was put forward to solve problems ice damage delivery canals during winter operation period in cold regions. Firstly, a circulating flume test system designed an indoor radiation- and temperature-controlled environment. Secondly, five groups comparative tests were carried out according different application scenarios. Lastly, combined w...

There are various methods for the analysis of the interactional behavior of the surrounding land, using the lining structure which is the most common method of deigning lining structure tools for the static loads by using the hyper static methods. In recent years, there has been a question that depicts whether this method provides the best results in designing the tunnel structure or not.Due to...

Wall displacements and ground pressure acting on the lining of a tunnel increase with time. These time-dependent deformations are both due to face advance effect and to the time-dependent behavior of the rock mass.  Viscoelastic materials exhibit both viscous and elastic behaviors. Thorough this study, the effect of different linear viscoelastic models including Maxwell, Kelvin and Kelvin-Voigt...

PURPOSE To determine the distribution of mRNA expression of the trabecular meshwork-induced glucocorticoid response protein/myocilin (TIGR/MYOC) in human trabecular meshwork. METHODS In situ hybridization using a 1.25-kb probe obtained from reverse transcription-polymerase chain reaction of TIGR/MYOC cDNA was performed to determine the location of cell labeling within the different regions of...

BACKGROUND/PURPOSE Anal canal duplication (ACD) is the most distal and the least frequent digestive duplication. A review of the English-language literature found 15 cases reported in the pediatric age group. METHODS A retrospective chart review was performed for our experience from 1999 to 2001 with 6 patients who presented with a midline postanal opening. RESULTS All of 6 patients were gi...

As an important component of water conservancy infrastructure, canals help improve the uneven distribution regional resources. However, in their construction and operation processes, which are affected by a variety complex factors, canal linings often produce various problems that greatly reduce overall quality lead to resources being wasted. To evaluate determine factors key procedures affecti...
