Do we need an international regime on access to genetic resources and benefit sharing (ABS) ? The Seventh Conference of the Parties (COP) of the Convention on Biological Diversity (CBD, 2003) to be held in February 2004 will probably give a political answer to this question. However, we would hope there is time for further legal, technical and economic analysis of this proposal before a definit...

Outstanding among the global environmental issues that have emerged since the 1980s is the issue of the rapid loss of biodiversity. This is an issue that is urgent from the ecological standpoint and strategic from the economic, political and social standpoints. With the Convention on Biological Diversity (CBD, 1992) a new global framework was introduced, together with a new international code o...

BACKGROUND The quantities of Legionella vary considerably from natural waters to water in contaminated domestic hot water supplies, whirlpool spas and cooling towers, with the risk for LD rising as the Legionella counts grow. We currently report the results from our Quantitative Microbial Risk Assessment (QMRA) model evaluation. We developed the LD QMRA model to better understand Legionella exp...

Thermal remediation of the soil contaminated with crude oil using microwave heating enhanced by carbon fiber (CF) was explored. The contaminated soil was treated with 2.45 GHz microwave, and CF was added to improve the conversion of microwave energy into thermal energy to heat the soil. During microwave heating, the oil contaminant was removed from the soil matrix and recovered by a condensatio...

AISI 304 stainless steel categorized under austenitic, has good resistance to corrosion and applicable for high pitting stresses. But it poor hardness, sterngth wear. In order overcome the above problem, various hardening techniques like nitriding, carburizing, carbonitriding, Cyaniding etc are preferred. this work, aqueous soluted nitriding process is carried out improve surface hardness wear ...

This research work aims to study the effect of 2wt%Mo on bainitic transformation kinetics and bainite morphology in 0.6wt%C-1.2wt%Si-1.0wt%Mn-0.2wt%Cr steel. Specimens are austenitized at 950°C rapidly cooled salt bath isothermally treated between 200°C–300°C for different time intervals. Another set specimens oil after an austenitization treatment then tempered temperature range 200°C–550°C. I...

The recent commercial success of foldable smartphones is indebted in part to integration ultra-thin glass (UTG) into the flexible display modules. To endow with such a foldability, while keeping its merits over polymeric materials, tons complicated issues need be resolved addition thickness reduction. Since UTG subjected repeated deformations during service as cover window, extra care required ...

Our objectives were to stabilize a non-clinical suspension for use in toxicological studies and develop methods investigate the stability of formulation terms salt disproportionation. The compound under research was hydrochloride practically insoluble discovery ODM-203. first three approaches prepared stored at room temperature. second stabilized by pH adjustment. In third approach cooling used...

This paper deals with the importance of educational methodologies which enable linear and propaedeutic education to be eliminated, while problematization dialogicity are stimulated. It describes a study that focuses on evaluation Three Pedagogical Moments (3 PMs) planned implemented activities in workshop "Coarse salt bath solutions", was carried out high school students chemistry classes. Work...

The antigen was made thus: to 1 ml. of Kahn antigen was added a "small quantity" of a fat stain (Scharlach R or Sudan 111) and four drops of tinct. benzoini co., B.P. The mixture was warmed in a water-bath at 50' C., and 10 ml. of 1.5 per cent saline, also warmed to 50' C., was added. This pink, milkylooking fluid was "sensitized" by the addition of varying amounts of 9 per cent salt solution. ...
