The paper discusses anticorrosive materials developed by JSC “СRONOS SPb” for different application oil/gas industry. A series of coatings were tested compliance with industrial Russian and international standards. Epoxy KronEpur 80 NKT the internal surfaces pipelines tubing high Tg comply state standard GOST 58346. KronTag RFID tags protection meet requirements according Hybrid epoxy-urethane ...

In electrical machinery, the rotor windings’ internal short-circuit faults are addressed by instantaneous over-current protection of power electronic excitation device, which has low sensitivity and difficulty meeting safety requirements. this paper, a fault method is proposed based on harmonic characteristics circulating current between stator branches. The magnetomotive force distribution coi...

• Internal dependencies. Many dependencies exist between software modules, and con icts on scheduling deployments exist between projects. • External dependencies. Longterm dependencies on thirdparty libraries exist, and change requests to those libraries cause delays. • Organically grown processes. Processes emerge as needed, usually after a crisis, and are often introduced locally rather than ...

We present a technique for replacement of the aortic valve in selected patients undergoing redo surgery in the presence of patent coronary artery bypass grafts and occluded native coronary arteries that affords optimal myocardial protection, limited dissection of the heart and minimal risk of injury to existing grafts, in particular, the internal mammary artery.

The aim of this paper is the presentation of some marketing strategies for textiles and clothing products in the global and European Single Market. This presentation is based on conditions for the completion of the internal market with special reference to trade creation and trade diversion effects, and on the norms and standards related to quality, natural environment and consumer protection.

Aim of this paper is to protect a transmission line section/feeder from internal faults by means of differential protection through a microprocessor. The conventional differential relay operates on the circulating current principle, which involves a direct comparison of the magnitude and phase of the currents entering and leaving the protected equipment or line section. The present scheme is ba...
