The article discusses researches performed in the Well Drilling Department of the St. Petersburg Mining University. The directions of development of the department are shown. Special attention in this article is paid to research in the field of developing drilling fluids for drilling wells in various mining and geological conditions. It is shown that the gas-liquid mixtures studied by the depar...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

abstract the balvard metamorphic assemblage (bma) crops out at the northeastern margin of the southeastern part of the sanandaj-sirjan zone (ssz) in contacting to the dehshir-baft ophiolitic mélange. this location prepared a special situation to resolve some of the complicated tectonic problems of this part of iran. petrology, micro-tectonics and satellite image investigation were carried out ...
Biomedical searching strategies are ever more complex in the nowadays “information deluge” context. MEDPILOT is a service freely offered by ZB MED – Deutsche Zentralbibliotek für Medizin (German National Medical Library) based on an effective meta-search engine. It runs searches in Medline/PubMed and in many other biomedical sources, and allows further refinements and clustering of results.
The antagonism, by neostigmine, of neuromuscular blockade produced by either Org NC 45 or pancuronium was studied in 29 anaesthetized patients during a continuous infusion of the myoneural blocker. The ED50 of neostigmine (dose which produced a 50% antagonism) when antagonizing Org NC 45 and pancuronium was 0.011 mg kg-1 and 0.010 mg kg-1 respectively. The dose-response relationships for the an...
Well killing is an important technological stage before conducting workover operation, one of the tasks which to preserve and restore natural filtration characteristics bottomhole formation zone (BFZ). Special attention should be paid choice well technologies development wells in complicated conditions, include abnormally low reservoir pressure, high oil-gas ratio carbonate type. To productive ...
Received: March 17, 2017 Revised: July 25, 2017 Accepted: August 18, 2017 Abstract: Introduction: For technical renovation of the thermal plant, one frame structure workshop of 50,000 m construction area and one reinforcement concrete chimney of 150m height shall be demolished by blasting in the same time. The engineering environment is very complicated and the accommodation space for the struc...
