The paper focuses on the issues of health and safety management in chemical industry enterprises. First, the significance of health and safety management for chemical industry enterprises is presented, followed by approaches to this area, including the selected results that have been achieved since 1998 within European chemical industry. Attention is primarily paid to the occupational health pr...

in this paper, a reaction system consisting of two parallel, non-isothermal autocatalytic reactions in a continuous stirred tank reactor (cstr) has been considered. reactor chaotic behavior is possible for certain values of system parameters. two types of controllers are designed and compared in order to control both the reactor temperature and the product concentration. the first controller is...

Background: The Neonatal Abstinence Syndrome (NAS) has been treated so far by various drugs, such as opioids and non-opioids. There is some concern about NAS babies who receive chemical drug treatment. Some researchers mentioned that shorter pharmacological treatment and less lengthy hospitalization are associated with severa...

We have reviewed published anthraquinone applications for international pest management and agricultural crop protection from 1943 to 2016. Anthraquinone (AQ) is commonly found in dyes, pigments and many plants and organisms. Avian repellent research with AQ began in the 1940s. In the context of pest management, AQ is currently used as a chemical repellent, perch deterrent, insecticide and feed...

The proper management of solid waste is the need of the time. The solid waste consists of various components, some of them are biodegradable where as other are non biodegradable. The waste from various biodegradable sources could be utilized as a feed material for the gas production. The objective of this study is food waste management through biogas production. Various parameters were studied ...

abstract: in this study the non-saponifiable matter of oils extracted from nine varieties of sunflower seed were subjected a series of chemical tests. the non-saponifiable matters were fractionated into a number of chemical classes of compounds namely sterols, 4 methyl sterols, triterpene alcohols, tocopherols and hydrocarbons. the two major and important classes of compounds consisting of ster...

in order to present a new and high performance structure of pem fuel cell and study the influence of the flow direction and distribution on the rate of reactants diffusion, three novel models of vertical reactant flow injection into the anode and cathode reaction area field have been introduced. they consist of one inlet and two inlets and also a continuous channel. the governing equations on t...

the heat and mass transfer analysis for mhd casson fluid boundary layer flow over a permeable stretching sheet through a porous medium is carried out. the effect of non-uniform heat generation/absorption and chemical reaction are considered in heat and mass transport equations correspondingly. the heat transfer analysis has been carried out for two different heating processes namely; the prescr...
