a few years after the implementation of computerize maintenance management systems (cmms), showing the analysis results of the collected data in these systems is necessary and important for continuing the usage of these systems. equipment downtime and cost data can identify patterns of equipment faults and equipment costs. it can also show deficiencies in the implementation of maintenance syste...

A set of equipment for an obstetric flying squad is described. It is aimed at providing the sequence: pre-oxygenation, intravenous barbiturate, suxamethonium, endotracheal tube, nitrous oxide, oxygen, intermittent suxamethonium and intermittent positive pressure respiration. A certain amount of variation in technique is also allowed for. Details of thirty emergency cases anaesthetized with the ...

For organisms with complex life histories, carry-over effects (COEs) can manifest between life stages, when conditions experienced by one stage influence the next, as well as trans-generationally, when the parental environment affects offspring. Here we used multiple global change-associated stressors to examine both forms of COE simultaneously in an intertidal limpet with mixed development (i....

This paper seeks to analyze the way investors consider growth option values when pricing equity. To achieve this objective we study the effect on stock prices of a comparative case of direct foreign investment involving acquisition of two different growth options, whose valuation has already been well-documented in prior literature. The case consists of the two sequential investment stages carr...

The article describes an attempt to solve at once three basic problems arising at testing a complex digital equipment for defects: 1) the problem of an exponential increasing of the complexity of testing the equipment with the complexity of the equipment; 2) the problem of testing of the tester; 3) the problem of a mutual masking of defects. The proposed solution is nothing more than using cert...

Background The installation of electrical equipment in adverse environments containing corrosive gases, liquids, or dust can cause severe and rapid deterioration of the equipment. Historically, it has been recommended to customers to keep electrical equipment free of these contaminants through the use of special enclosures or separate rooms. Furthermore, the NEC (National Electrical Code) does ...

A method of building communication equipment simulator aiming at the difficult problem of large equipment training is presented. Simulator is built based on virtual reality and its framework is designed to layered architecture and framework. Geometry model of equipment simulator is created with software named Multigen Creator. Its key technologies including geometry modeling, training environme...
