A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to ch...

Vibration is an inevitable phenomenon in the coal cutting process and severe vibration leads to efficiency loss for equipment. To understand impact of on equipment explore measures improve stability, dynamic response analyzed. The shearer drum, which always undertakes task source working process, established with finite element method relations between performance characteristics are Hydraulic ...

The recent earthquakes in Christchurch led to the redevelopment of the University of Canterbury’s Seismic Equipment Laboratory (SEL). The SEL facility will involve the testing of building structures subject to simulated static and dynamic displacements from earthquakes, with a reaction wall and floor used to exert loads by way of hydraulic actuators on test specimens, and shaker tables used to ...

The future More Electric Aircraft (MEA) technology focus on increasing the use of electrical equipment to a larger extent, e.g. replacing conventional hydraulic and pneumatic actuators with electromechanical or electro hydrostatic actuators to reduce weight, cost and maintenance. Advances in enabling technologies of electric power generation, distribution, and utility equipment have made the us...

Maintenance and reliability are crucial aspects for operating construction equipment in harsh environmental conditions. One of the methods used to improve maintenance is oil diagnosis. In this study, monitoring conditions was performed through use an integrated sensor hydraulic equipment. Hydraulic polluted by various materials such as moisture dust. Therefore, present work investigated change ...

The article is about to the calculation of main technical parameters directional air-hydraulic hood. It accepted as a mathematical model wave equations hyperbolic type applied pressure pipelines pumping stations, and analytical solutions for different values polytropic exponents are proposed. Water hammer poses danger normal operation equipment control measuring equipment, devices pipelines. To...

BACKGROUND Injuries due to high-pressure injections are frequently underestimated occupational accidents, which may have disabling outcomes. METHODS The occupational injuries logbooks of two shipyards were examined. Twelve accidents due to the utilization of high-pressure equipment were reported. Data were obtained by reviewing the employers' logbooks and hospital records. RESULTS Contamina...

A convenience survey of 702 certified pesticide applicators was conducted in three states to assess the use of 16 types of engineering controls and 13 types of personal protective equipment (PPE). Results showed that 8 out of 16 engineering devices were adopted by more than 50% of the respondents. The type of crop, size of agricultural operation, and the type of pesticide application equipment ...
