INTRODUCTION Hyperbaric work was conducted for constructing an underground tramway in the Netherlands. A total of 11,647 exposures were conducted in 41,957 hours. For these working conditions specifically developed oxygen decompression tables were used. METHODS Fifteen workers were submitted to Doppler monitoring after caisson work at a depth at 12 msw. Measurements were done according to the...

BACKGROUND Noise is defined as a sound or series of sounds that are considered to be invasive, irritating, objectionable and disruptive to the quality of daily life. Noise is one of the environmental pollutants, and in cities it is usually originated from road traffic, railway traffic, airports, industry etc. The tram is generally considered as environmentally friendly, namely non-polluting and...

Tram rail transport is one of the important systems in underground coal mines. The stability tramway system a mine influenced by many factors, such as geological and mining conditions. In order to evaluate tracks mines, monitoring activities are carried out periodically. This activity provide accurate data on current status system, early detection displacement deformation system. paper presents...

The study aims to evaluate the efficiency of tram track in urban transport system Algerian city Setif by combining Analytical Hierarchy Process (AHP) and Geographic Information System (GIS) approach. In this research, a set multiple pre-determined criteria applicable field were selected for decision-making. They collected from recent research literature expert opinions discipline, then arranged...
