The protection of continuous drinking water supply is really important all over the world, also in Hungary. Many kinds of hazardous chemicals could pollute the natural water resources, arsenic is one of the most occurring pollutant in Hungary. Recently, an ethylene-vinyl alcohol copolymer based arsenic removal adsorbent has been developed. During the manufacturing process hazardous waste water is produced, which is burned in the incineration plant, so this open production process needs fresh solvent every time. However, if the different fraction of the waste water is separated by distillation both the volume of the hazardous waste water can be reduced extremely and the recovered solvent and water can be reused in the manufacturing process. Beside analytical measurements Life Cycle Sustainability Assessment (LCSA) was prepared to identify and compare the environmental, economic and social effects of the current technology and the new one. The results proved that the technology closed by distillation is better than the current open one in each aspect of LCSA.

Flow Experiences

Traditional gravity pour down-sprue methods of filling moulds in the making of aluminum castings inherently lead to oxide and air bubble entrainment. The reason for this is found in the high velocities the metal flow experiences during the filling of a mould. The Nemak Windsor Aluminum Plant (WAP) produces cylinder blocks using the low-pressure Cosworth process, which includes low velocity up-hill filling of the sand mould package. This doctrine is followed in all except one part of the process: the runner system. The nature of the resulting defect is generally known as Head Deck Porosity. Runners were cast full in open production runners at three different velocities with the resulting quickly chilled castings analyzed using X-ray radioscopy, and Scanning Electron Microscopy. Results reveal that the subject bubble porosity is indeed the result of air entrained during initial transient flow within the production runner system whose velocity is higher than the critical value of 0.5ms-1. This theoretical value is corroborated by experimental results. In addition, a new "sessile" runner of optimized shape, filled at a velocity slower than the critical value, is proposed and analyzed using Magmasoft mould fill modelling software. The design can potentially replace the existing runner providing a casting free of entrained air.

AbstractIn 2008, California passed Proposition 2, specifying confinement space for certain farm animals. Proposition 2 went into full effect January 2015 and has significant implications for egg production in California and possibly even interstate commerce. We examined the influence of promotional videos aired during the campaign on consumers’ willingness-to-pay for eggs produced in a more open production system (i.e., cage-free, free range) and corresponding neurofunctional activations during decisions. Forty-six participants (24 females), aged 18–55 years (

The research is dedicated to the multi-structural model of the complex system at the construction enterprise as well as the model of structurally functional open production-and-economic system at the construction enterprise. The models are created for the acceptance of the justified managerial decisions and carrying out the applied research aimed at the efficiency of the construction enterprises functioning in the conditions of uncertainty, instability of the internal and external environment and heterogeneity of the indicators, which characterize the enterprise’s activity. The offered models are developed on the basis of the probability theory and the information theory; they are based on the principles of self-organization, openness of the complex systems, synergy and information-and-statistical approach. The concept of the open productive-and-economic system at the construction enterprise is considered, the content of the functions of the complex system at the construction enterprise is described, their stochastic and quasi-determined communications in the uniform information-and-statistical field of functioning are presented. Bit measurement for the whole set of functions, allowing to receive an adequate assessment of the complex open system behavior, is offered for further scientific and applied research, including the development of more exact forecasts and improvement of statistical heterogeneity of indicators.
