After spontaneous elimination of 81 drug packets, the patient had three unremarkable stools. A plain abdominal X-ray disclosed no residual packet but computed tomography (CT) scan showed one in the sto...

[1] Single-hole hydrogeologic experiments were conducted with a drillstring packer in Integrated Ocean Drilling Program Hole 1301B, which penetrates 318 m into 3.5-Ma upper oceanic basement on the eastern flank of the Juan de Fuca Ridge. Seven constant-rate injection tests were conducted in open hole, with the packer inflated at three depths in the deepest 166 m of the basement section. The pri...

The research aims to develop a seed drill for precise seeding on ridge with drip irrigation. basic principles and methods of classical mechanics, mathematical analysis, statistics were used in this study. existing technologies sowing cotton seeds are analyzed. authors have developed method the crest irrigation its implementation, including working body fertilizer, shaper gasket comb attached hi...

The article considers the general shortcomings of packers designed for carrying out geological and technical measures in an open hole. These packer deficiencies can cause problems operation wells, which leads to increase non-productive time or even loss a well and, as result, high costs oil gas companies. design sliding support elements, centering structure hole, preventing leakage sealing rubb...
