The main purpose of this study was to determine the factors affecting the export of flowers in Iran. After data collection using by the index of Revealed Comparative Advantage (RCA), the condition of business of flowers in Iran was compared with a number of countries exporting the product. According to the results of study, the small elasticity of the exportation price in the function of export...

sugar beet as an industrial crop plays a main role in satisfying domestic demand of sugar. study on the production efficiency of sugar beet is important because this is a factor that influences production without additional cost. in this study, data envelopment analysis approach (dea), was implemented to calculate technical, administrative and scale efficiency of sugar beet production. also opt...

The Nigerian rice sector has made remarkable improvement in the last decade as production has increased significantly thereby reducing the gap between domestic supply and demand. In the last three decades, rice imports make up greater proportion of Nigerian imports as rice forms a structural component of the Nigerian diet. Past government inconsistent policies were not successful in securing go...

Biohydrogen is considered a promising and environmentally friendly energy source. Escherichia coli BW25113 hyaB hybC hycA fdoG frdc ldhA aceE has been previously engineered for elevated biohydrogen production from glucose. In this study, we show that this strain can also use biomass from oil palm frond (OPF) juice and sewage sludge as substrates. Substrate improvement was accomplished when hydr...

Jordan is extremely water-scarce with just 167 m3 per capita per year to meet domestic, industrial, agricultural, tourism, and environmental demands. The heavy exploitation of water resources has contributed to declines in the levels of aquifers and the Dead Sea. Rapid growth in demand, particularly for higher quality water for domestic, industrial, and tourism uses, is significantly increasing...

• We test if and where industrial policy to promote ‘green’ industry development can improve competitiveness in export markets. Proponents of ‘green growth’ have argued that domestic promotion of ‘green’ energy will generate improved comparative advantage in export markets for high-technology goods such as wind turbines or solar cells. If this holds depends on if domestic market expansion can, ...

Biosolids are solid, semi-solid, or liquid materials resulting from the treatment of domestic sewage sludge. The term “biosolids” was introduced by the wastewater treatment industry in the early 1990’s and has been adopted by the United States Environmental Protection Agency (U.S. EPA) to distinguish high quality, treated sewage sludge from raw sewage sludge and from sewage sludge containing la...

BACKGROUND During the summers of 1989-1992 we conducted four randomized intervention trials at four separate UK bathing locations judged of acceptable quality under current USEPA and EU criteria. The results showed bathers to be at increased risk of gastroenteritis, acute febrile respiratory illness (ICD-9 461-466, 480), ear and eye infections relative to non-bathers. The public health signific...

CWMFC is a novel technology that has been used for almost decade concurrent wastewater treatment and electricity generation in varying scopes of domestic, municipal, industrial applications since its implementation 2012. Its advantage low-cost enhanced sustainable bioelectricity gained considerable attention. Nevertheless, the overall efficiency this inclined by several operating factors config...
