The transition from aquatic to aerial respiration is associated with dramatic physiological changes in relation to gas exchange, ion regulation, acid-base balance and nitrogenous waste excretion. Arapaima gigas is one of the most obligate extant air-breathing fishes, representing a remarkable model system to investigate (1) how the transition from aquatic to aerial respiration affects gill desi...

Surface soils from Guiyu, China (an intense e-waste processing center) were analyzed for persistent organic pollutants (POPs) and variations in composition of the resident bacterial communities. Denaturing Gradient Gel Electrophoresis analysis of bacterial 16S rRNA gene showed that e-waste pollution altered the bacterial community structure by promoting changes in species composition and specie...

I ssues pertaining to the disposal of surgical waste are seldom discussed in the dermatologic surgery literature. Management of surgical waste as pertaining to the surgeon includes proper disposal of sharps in appropriate containers as well as proper handling and disposal of infectious nonsharp materials. Attention should be paid to two particular issues. First and foremost is to minimize the r...

The effects of three different traditional processing methods (smoking, frying and salting) on proximate composition of red fish stored under ambient room conditions were determined. Fresh red fish were obtained from Elmina fish market. These were used for the study to determine the proximate properties of the raw fish, smoked fish, fried fish and salted fish before and after storage. The param...

There has been a paradigm shift towards reclamation of wastewater from high cost to low cost effective technology for treatment of sewage and resource utilization for economy driven activities.Under appropriate conditions, sewage fed fisheries would reduce the cost of fish production by utilizing the sewage induced natural plankton and become cost effective because of savings through chemical f...

E-waste is a complex waste category containing both hazardous and valuable substances. It demands for a cost-efficient treatment system which simultaneously liberates and refines target fractions in an environmentally sound way. In most developing countries there is a lack of systems covering all steps from disposal until final processing due to limited infrastructure and access to technologies...

Mercury Levels Lower in Great Lakes, but Still High Although mercury concentrations have decreased about 20% in fish, fish-eating birds, and inland lake sediments across the Great Lakes region in recent decades, levels in top predator fish and wildlife are still dangerously high, and in some places concentrations in some fish and wildlife may now be increasing, according to a new report. Levels...

Currently, Construction and Demolition waste (C&D waste) is a worldwide issue that concerns not only the construction management level of on-site managers but also the sustainable development of construction industry. In this paper, detailed formulas are listed for calculating the costs of three typical kinds of disposal routes of C&D waste. They are Landfill Disposal, Recycling and Reuse. Usin...
