Evaporation of a pure liquid into a inert gas is studied theoretically and experimentally. In contrast with the case where the gas phase is made of pure vapor, the thermocapillary (Marangoni) effect strongly destabilizes the system, and results in intensive and often chaotic forms of interfacial convection. Theoretically, a generalized one-sided model is proposed, which allows to solve thermo-h...

The paper assesses blood alcohol concentration and risk behaviors for traffic accidents before and after the implementation of a law which prohibits the use of alcoholic beverages on city gas stations. In Porto Alegre, Southern Brazil, young people go out at night and drive to gas station convenience stores to buy alcoholic beverages which are consumed on the premises of parking lots in gas sta...

This paper describes the ongoing project on autonomous spilled oil and gas tracking buoy system and application to marine disaster prevention system for 5 years since FY2011 (http://www.naoe.eng.osaka-u.ac.jp/~kato/project/). The objectives of this project are as (1)autonomous tracking and monitoring of spilled plumes of oil and gas from subsea production facilities by an underwater buoy robot,...

In this paper a multi-criteria fuel distribution problem similar to the common CVRP is considered with the real-life coordinates of gas stations obtained from a certain petrol company. The optimized criteria are the total distance of all tours and the number of tours. A certain method of solution representation, which ensures a feasible solution was used along a decoding scheme. A simulated ann...

Coal is mined in every country which is mainly used to generate electricity. Thousands of mine workers were killed every year due to many disasters takes place inside coal mine. These accidents are caused mainly due to the leakage of poisonous gas [2] present in the mine. Especially developing countries face a poor safety system for mine workers. Hence it requires a safety monitoring system [1]...

A fire on the Mir space station in 1997 threatened the spacecraft and its crew of six [1]. The fire involved an oxygen jet leaking from a lithium–perchlorate oxygen generator. The fire involved three factors not normally encountered in terrestrial fires: enhanced oxygen, inverse flames (in that the oxidizer is surrounded by fuel), and microgravity. The present work examines some effects of thes...

The aim of this paper is to examine the impact of temperature shock on both near-month and far-month natural gas and heating oil futures returns by extending the weather and storage models of the previous study. Several notable findings from the empirical studies are presented. First, the expected temperature shock significantly and positively affects both the near-month and far-month natural g...

consumption of leaded gasoline in iran cause to emit lead compounds in ambient air of gasoline stations and is known to effect on workers health in these locations. the objectives of this study were assessment of ambient lead levels and blood lead levels of gasoline station workers in hamadan city, iran. for this purpose, 82 samples were obtained in ambient air of gasoline station locations. se...

This paper discusses examples, p a r t i c u l a r l y hypo the t i ca ls , t he i r use and generat ion, in legal reasoning. It examines the use of sequences of hypo the t i ca ls .

– World wide drilling is developing for oil, gas or water resources. Electric motors power 75% of the total drilling rigs installation, augmenting to 95% for the case of Romania. Monitoring diesel generators micro-power station and motors of the rig is the second important thing to do and complete the main task of drilling process monitoring. This paper describe a monitoring and control system ...
