Length-weight relationships (W = aLb) were estimated for 5 fish species, the pearl stingray Fontitrygon margaritella (Compagno & Roberts, 1984), West African spadefish Chaetodipterus lippei (Steindachner, 1895), East Atlantic Ephippus goreensis (Cuvier, 1831), law croaker Pseudotolithus senegallus 1830) and Guinean sole Dagetichthys cadenati (Chabanaud, 1948). Fishes collected during several sc...

in mulberry (morus sp.), grown for its foliage, which is the sole food for the silkworm (bombyx mori l.), evolving high yielding varieties is a long drawn and laborious process. one of the important selection parameter that has significant positive correlation with leaf yield is total shoot length [tsl] of the mulberry plant. measuring the length of all the shoots of the test genotypes to get t...

this work reports the comparative study of heavy metal water concentrations fromtwo coastal ecosystems ofcadizgulf (swspain): bay of cadiz and ria ofhuelva estuary in samplestaken on years 1999-2000. sampling zones showed different heavymetal levels. statistical analysisof dissolved trace metal concentrations (cu, zn, cd and pb) showed significant differences betweenhuelva and cadiz zones based...

Linkage maps based on markers derived from genes are essential evolutionary tools for commercial marine fish to help identify genomic regions associated with complex traits and subject to selective forces at play during exploitation or selective breeding. Additionally, they allow the use of genomic information from other related species for which more detailed information is available. Sole (so...

OBJECTIVE A prospective randomized study was conducted in order to analyze the role of fibrinolytics in the treatment of complicated parapneumonic effusion. METHODS From 2001 to 2004, 127 consecutive patients were managed for thoracic empyema. In all cases the cause was bacterial pneumonia. Seventy patients were managed with sole tube thoracostomy (group A) and 57 with combination of tube tho...

Pricing schemes for Internet services have turned out to be of crucial influence for the competitiveness of Internet Service Providers (ISP). Despite of this urgent demand, there is still no standard tariff scheme that solves the so-called “feasibility problem”, i.e. ensures simultaneously technical feasibility, economic efficiency and user acceptance. This paper investigates the reason for the...
