Sand coverings account for a large part of the cost of a project. The purpose of this study is to evaluate the performance of different coatings for filtration of underground drains and reduce the cost of cornfield farms. The experiments were carried out in farm in Salman Farsi. The subsoil drainage was fitted to each test piece with a length of 120 meters, a diameter of 100 mm, and a distance ...

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...

Background: Historically open surgical drainage has been the treatment of choice for pyogenic liver abscess. The records of 54 patients with pyogenic liver abscess were reviewed to determine whether earlier diagnosis with current imaging tests and definitive treatment with antibiotics and aspiration drainage was an effective alternative to surgery. Methods: The clinical features, laborator...

Urban flooding is a complex natural hazard, driven by the interaction between several parameters related to urban development in context of climate change, which makes it highly variable space and time challenging predict. In this study, we apply multivariate analysis method (PCA) four machine learning algorithms investigate map variability vulnerability floods city Tangier, northern Morocco. T...

abstract although lateral drains play the main role in removal of excess water from soil profile in subsurface drainage systems, but it is assumed that perforated collectors can directly remove a part of drainwater from soils. this part of discharge in subsurface drains is not usually taken into consideration in drainage design criteria, due to lack required information and its difficult estima...

Undoubtedly, land degradation linked to desertification causes a decrease in qualitative and quantitative features of natural resources. This research aimed to assess land desertification by local residents and their role in controlling desertification in Isfahan province, Iran in 2016. The criteria were soil climate, vegetation, erosion, and demography. The indicators of soil texture, stone fr...

A 65-year-old Japanese woman was presented with a 2-day history of fever. The patient had undergone a surgery for uterine myoma 20 years prior. Drug history was unremarkable except for acetaminophen use. On admission, her temperature was 39.9 C; she had tachycardia (117 beats/min) and no abdominal pain. A contrast-enhanced abdominal computed tomography revealed multiple multiloculated low-densi...
