Safety risk study on road transportation of hazardous chemicals is a reliable basis for the government to formulate transportation planning and preparing emergent schemes, but also is an important reference for safety risk managers to carry out dangerous chemicals safety risk managers. Based on the analysis of the transport safety risk of dangerous chemicals at home and abroad, this paper studi...

Abstract The current rise in global energy demand has led to environmental concerns such as resource depletion and pollution. This steered researchers towards exploring different renewable sources achieve a sustainable circular bio-economy. Interestingly, the abundant nature of lignocellulose biomass (LCB) attracted lot attention production various specialty chemicals fuels. valorization LCB re...

Land application systems, also referred to as beneficial reuse systems, are engineered systems that have defined and permitted application areas based on site and waste characteristics to determine the land area size requirement. These terrestrial systems have orders of magnitude greater microbial capability and residence time to achieve decomposition and assimilation compared with aquatic syst...

in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

PURPOSE To analyze how carbonated thin liquids affected the physiology of swallowing in dysphagic patients. MATERIAL AND METHODS 40 patients were analyzed; 36 were neurologically impaired. During a therapeutic videoradiographic swallowing examination the patients had to swallow liquids with the following consistencies three times: thin, thickened and carbonated. The liquids were given in dose...

nucleate pool boiling heat transfer coefficient have been experimentally measured on a horizontal rod heater for various liquid binary mixtures. measurements are based on more than three hundred data points on a wide range of concentrations and heat fluxes. in this investigation, it has been confirmed that the heat transfer coefficient in boiling solutions are regularly less than those in pure ...

The hydrogen bond donor-promoted fixation of CO(2) and epoxides into cyclic carbonates was investigated through experimental and density functional theory studies. A highly effective homogeneous system of 1,2-benzenediol-tetrabutyl ammonium bromide (TBAB) and heterogeneous poly-ionic liquids were developed for the fixation of CO(2) into cyclic carbonates via hydrogen bond activation, based on t...

Clayey soils are the most common material used for water sealing and undertake an important role in controlling landfill-related pollution. Organic liquids can adversely affect the effectiveness of clay liners by drastically increasing their hydraulic conductivity. The aim of this study is to investigate and compare the permeability in two types of clay with different plasticity, exposed to the...
