Photocatalytic properties of hierarchical CuO nanosheets synthesized by a solution phase method

CuO nanomaterials were synthesized by a simple solution phase method using cetyltrimethylammonium bromide(CTAB) as a surfactant and their photocatalytic property was determined towards the visible-light assisted degradation of Reactive Black-5 dye. A detailed mechanism for the formation of CuO nanostructures has been proposed.The effect of various experimental parameters such as catalyst amount, dye concentration,p H and oxidizing agent on the dye degradation efficiency was studied. About 87% dye was degraded at p H 2 in the presence of CuO nanosheets under visible light. The enhanced photocatalytic activity of CuO nanosheets can be ascribed to good crystallinity, grain size,surface morphology and a strong absorption in the visible region. CuO is found to be a promising catalyst for industrial waste water treatment.     

Simulation of Jeddah multi-port sea outfall

Jeddah wastewater multi-port outfall was analyzed using CORMIX2 for average ambient conditions. The numerical analysis of the outfall shows that the near-field mixing extends 187.5 m downstream of the diffuser and the dilution at the end of near-field reaches 1,047.8. The concentration of the plume drops sharply from 100 at the exit point to 0.0954 at the end of near-field zone. In the far-field zone the reduction in concentration is gradual and will reach 0.0061 at a distance of 20,000 m downstream of the diffuser, while dilution exceeds 16,440 at this point. The plume rises rapidly due to the buoyancy and touches the water surface at a distance of 187.5 m downstream. The thickness of the plume reaches a maximum value of 37.5 m at the interface of near-field and far-Field zones, and then it starts spreading horizontally maintaining a thickness of about 13 m over a distance of about 4 km. As the plume mixes with ambient sea water, it starts spreading again in vertical direction and fills the entire water depth at a distance of 18,927 m down stream. The plume maintains nearly a constant width in the near-field zone but spreads progressively horizontally in the far-field zone till the plume touches the left bank at a distance of 18,482.52 m downstream. The plume spreads at a distance of 2,069 m from the coastline at the end of simulation zone. It can be concluded from numerical results that if the discharged water meets local and international standards for treated wastewater, the plume will not pose any threats to the local venerable environment as the dilution is considerably high due to high exit momentum and favorable cross current.     

A study of the Kazdagi (Mt. Ida) National Park: an ecological approach to the management of tourism

In the field of tourism, where environmental resources are the primary attraction, ecotourism is one of the sustainable approaches now considered as an alternative when considering today's increasing environmental problems. Indeed, according to the World Tourism Organisation, ecotourism is the fastest growing market within the tourist industry. The purpose of this study is to determine tourism activities sensitive to the environment, to help tourism in Turkey and neighbouring countries, and to help spread ecotourism by protecting biological species. The Kazdagi (Mt. Ida) area in Turkey is used as an example and case study.     

Individual demographic differences and job satisfaction

Empirical research and theoretical literature support the notion that demographic differences among employees are associated with job satisfaction. However, the evidence is inconsistent, and little is known about the stability of many of the reported relationships. A meta-analysis was conducted involving 21 independent studies and over 10,000 employees to discern selected population relationships. Results indicated that, with the exception of age and organizational tenure, associations do not differ significantly from zero. Large amounts of variance around each mean correlation, however, warranted a moderator analysis. Results indicated that the strength and pattern of associations differ by organizational type. Theoretical propositions and implications for future research in the area of demographic moderators are discussed.
