Since the 1980s of the 19th century, in "Dialectics of Nature" works, Friedrich Engels wrote: "we should not be too proud of our successes against the natural world. Because every time we achieve a success, the natural world will revenge us". So far Friedrich Engels's warning have still had practical value for the protection of rural environment in Vietnam.

The paper is focused on the stiffness analysis of the longitudinal arm of single-axle suspension on elasto-kinematic behaviour of the vehicle axle which is highly important when considering the handling characteristics related tovehicle safety.The elasto-kinematic behaviour of the axle determines the course of the geometrical parameters of wheel suspension, the toe angle and camber as the function of wheel movement during force loading. This paper presents the complex MBS (Multi-Body Simulation)model of the wheel suspension with nonlinear characteristics of rubber-metal bushings. The model also comprises force elements such as springs, shock absorbers, stops and the transverse stabilizer.............

:: 10.9790/1813-0602016268   

Production of methane CH4 from a mixture gas of carbon dioxide CO2 and hydrogen H2 has been established by two types of pulse discharges. One is an axial discharge with a use of thin pair Ni wire electrodes separated by a narrow gap, and the other is a coaxially radial discharge with a use of inner rod and outer tube electrodes made of stainless steel (SUS). The former provides an intense gap discharge, while the latter provides a gentle discharge in the annular region. Decomposition of CO2 is enhanced in the former case when Ni (nickel) mesh disc electrode is placed behind the gap. Ni is known as catalysis..............

The high volatility in fuel prices in the recent past, resulting turbulence in energy markets and the increase of the GHG has compelled many countries to look for alternate sources of energy, for both economic and environmental reasons. With growing public awareness about sanitation, and with increasing pressure on the government and urban local bodies to manage waste more efficiently, the Indian waste to energy sector is poised to grow at a rapid pace in the years to come. The dual pressing needs of waste management and reliable renewable energy source are creating attractive opportunities for investors and project developers in the waste to energy sector.

A distribution transformer is one of major electrical equipment that links the power utility and power consumers. It is what enables the power utility to supply electricity to consumers. In recent time, there has been an upsurge of distribution transformers premature failure before reaching the desired and designed service life. Consequently, the power utility has been incurring huge economical losses in replacing the faulty transformers or repairing them. On the other hand, failure of transformer inconveniencies power end users by interrupting the power supplies for prolonged period of time before the faulty transformer is replaced...............

This study aims to determine the diagnostic reference levels (DRLs) for posterior-anterior lumbar and profile lumbar examinations in order to optimize the entrance dose (De) and the dose area product (DAP) of patient in Abidjan. A total of 240 patients undergoing conventional radiology in four hospitals of the city were considered. The device used to measure De and DAP values is a DAP-meter, model Diamentor M4 KDK and of type 11017. The DRLs in terms of De and DAP values were determined by applying the 75th percentile method. These values were compared to DRLs values obtained in other countries and to those recommended by international institutions. The values of De measured are encouraging, however for the DAP; many efforts are needed to be made to reduce the DRLs values

This paper considers a queue, consisting of a Poisson input stream and a server. The server is subject to breakdowns. The times to failure of the server follows exponential distribution. The failed server requires repair at a facility, which has an unreliable repair crew. The repair times of the failed server follows exponential distribution, but the repair crew also subjects to breakdown when it is repairing. The times to failure of the repair crew is also assumed to be exponentially distributed. This paper obtains the steady-state performance of the queuewith server breakdowns and interrupted repairs.

Nonstop forwarding is designed to minimize packet loss when a management system fails to function. A system with non-stop forwarding can continue to forward some packets even in the event of a processor failure. We consider a Geo/Geo/1 N-limited nonstop forwarding queue. In the queueing system, when the server breaks down, up to customers can be serviced during the repair time.The delay distribution of customers is given by matrix geometric analysis..
