Economics of operation of 38' G.R.P. fishing vessels issued by the A.D.B. Fisheries Project: a case study

The author gives a financial and economic valuation of the operation of vessels in the 38 foot GRP class. He discusses particularly the materials and methods of fishing they use, species composition of their catches, their rate of return, break-even analysis, financial and social analysis.

Studies on the influence of moisture and specific gravity on the strength properties of mango wood (Mangifera indica)

Influence of moisture and specific gravity on the strength of mango wood is discussed. The co-efficient of correlation between specific gravity and breaking strength was found to be non-significant. The relation of strength and moisture was found to be highly significant. The mean strength values indicated a reduction in strength when the moisture increased from 8.5 to 18.8%. However no appreciable difference in strength values could be observed when moisture increased above 37%. The strength-moisture relationship is a straight line, passing approximately through the fibre saturation point. By using the exponential formula, the breaking strength corresponding to any moisture level between zero and fibre saturation can be determined.

Mitochondrial genomes of two luminous beetles, Rhagophthalmus lufengensis and R-ohbai (Arthropoda, Insecta, Coleoptera)

We determined the mitochondrial MA (mtDNA) sequences of two luminous beetles (Arthropoda, Insecta, Coleoptera), Rhagophthalmus lufengensis from Yunnan, China and Rhagophthalmus ohbai from Yaeyama Island, Japan. We identified all the 37 mtDNA genes of R. l
