the purpose of this research was to design a semi-industrial culture medium to obtain the maximum biomass production from bacterium bacillus subtilis utb96. in the first step, in order to reduce the cost of culture medium components, commercial products and industrial by products including, sugar beet molasses, sugar cane molasses, potato waste water and milk serum as carbon sources and corn st...

Languages based on the theory of timed automata are a well established approach for modelling and analysing real-time systems, with many applications both in industrial and academic context. Model checking for timed automata has been studied extensively during the last two decades; however, even now industrial-grade model checkers are available only for few timed automata dialects (in particula...

Legislation in North Carolina has mandated obtaining renewable energy from the incineration of poultry waste, resulting in proposals for three poultry-litter-fueled power plants statewide. This article summarizes environmental health and environmental justice issues associated with incineration of poultry waste for the generation of electric power. Emissions from poultry waste incineration incl...

We introduce a multi-level smooth transition model for a panel of time series, which can be used to examine the presence of common nonlinear business cycle features across many variables. The model is positioned in between a fully pooled model, which imposes such common features, and a fully heterogeneous model, which allows for unrestricted nonlinearity. We introduce a second-stage model linki...

In recent years, haze has occurred in many parts of China. This phenomenon a very negative impact on people’s health and production life. For long time, the main research direction environmental science experts China is to study analyze generation, causes, changes large particles haze. paper points out variance parameter model PM2.5 change improvement optimization College Students’ indicators. ...

The study offers updated and more accurate information about long-term annual solar resource in the most countries of Europe, Middle East and North Africa (EU-MENA) and evaluates PV power production potential. The underlying solar radiation and PV electricity output values are calculated form the solar and meteo database SolarGIS, which covers a history of recent 18 years. Direct Normal Irradia...

A Simple Theory of Industry Location and Residence Choice This paper provides a simple theory of geographical mobility which simultaneously explains people’s choice of residences in space and the location of industry. Residences are chosen on the basis of the utility which mobile households obtain across locations. The spatial pattern of industry is determined by the location decision of a scar...

Introduction The viability of rural communities and methods of food production is central to the health of the environment as well as humanity. So mounting evidence of the destructive and unsustainable ways more and more food is produced today is especially alarming. The prevailing model of economic development, widely referred to as globalization or neoliberalism, includes massive export-orien...

Azo dye decolourisation can be easily achieved by biological reduction under anaerobic conditions. The aim of this study was to evaluate the applicability of submerged anaerobic membrane bioreactors (SAMBRs) for the decolourisation of dyeing wastewater containing azo dyes. The reactive orange 16 was used as model of an azo dye. The results demonstrated that very high decolourisation (higher tha...
