MATERIAL AND METHODS Examination of paper death inquiry files, death registers, marine accident investigative files, annual casualty and dea...
Friedel-Crafts acylation of the aryldiazirine with ω-ester-α-acyl halide and successive reduction of the carbonyl group to methylene with triethylsilane and trifluoroacetic acid gave diazirinylated fatty acids. Photoaffinity labeling with the carbene generating precursor, 3-phenyl-3-trifluoromethyldiazirine, has become increasingly important as a photophor. However, the complicated synthesis of...
Southern African countries have a good cultural tourism development potential, and many countries in the region have identifi ed the development of cultural tourism as one of the key growth areas in tourism.

To create the new CPUE based on the fishing effort for searching skipjack fishing ground or fish school, GPS data loggers were deployed on 7 Japanese pole and line vessels(< 200 GRT) from July to September 2010. The position and speed of vessels were logged in every 1 second. Start and end time of fishing (angling) and skipjack catch (ton) of each fishing activities were recorded on the field n...
Using a bioeconomic model of the cod (Gadus morhua) and capelin (Mallotus villosus) fisheries of the Barents Sea, this study assesses the role of the fishermen’s behavior in reducing or intensifying the effects on the stocks caused by altered population dynamics. The analysis focuses on the economic development of the fisheries employing a coupled stock size–hydrography-based fishing strategy, ...
the use of methanesulfonic acid as a brønsted acid for direct ortho-acylation of phenols and naphthols proves to be a convenient, more general and direct route to various hydroxyaryl ketones. the route is regioselective, leading to ortho c-acylated products in satisfactory to high yields in most cases. the solvent free reactions described below exhibited environmentally benign in terms of faste...

Two coral species, Porites palmata and Porites lutea, were transplanted into three distinct management areas adjacent to the Mombasa Marine National Park, Kenya: A no-fishing MPA; a gear-restricted reserve with no beach seining; and a reserve with beach seining. Corallivory by fish or breakage by fishing gear was measured over a 57-day period. Porites palmata, the branching species, was more su...
