Numerical simulations are used to investigate the flow associated with a bluegill sunfish (Lepomis macrochirus) pectoral fin during steady forward motion. The simulations are intended to match the experiments of Lauder et al. (Bioinsp. Biomim., vol. 1, 2006, p. S25), and the results obtained from the simulations complement the experimental analysis. The focus of the current paper is on the quan...

This paper provides a brief summary of some of the recent research completed using radar observations of convective cloud systems associated with the North-Australian monsoon. The key focus is to describe the variability of convective cloud system properties as a function of the large scale regimes characterizing the region. This latter work is linked with the evaluation of the ACCESS model and...

The diurnal cycle of convective activity and cloudiness over Lake Victoria, is examined using infrared satellite data. The results indicate that geographically distinct patterns of convection occur. Maximum convective activity occurs over the northwestern quadrant of the lake and tends to occur during the night time. There is a similar pattern in the southwest but the convection is relatively i...

Eviota nigramembrana is described from the Ryukyu Islands, Japan and also recorded from the Philippine Islands. It belongs to the cephalic sensory-pore system pattern group I (complete), has a dorsal/anal fin-ray formula of 8/8, 5th pelvic-fin ray absent, some lower pectoral-fin rays branched, five dark internal bands between anal-fin origin and caudal fin, no distinct marking on pectoral-fin b...

Passive heat transfer from enclosures with rectangular fins is studied both experimentally and theoretically. Several sample enclosures with various lengths are prepared and tested. To calibrate the thermal measurements and the analyses, enclosures without fins (“bare” enclosures) are also prepared and tested. Surface temperature distribution is determined for various enclosure lengths and heat...

Finasteride (FIN) inhibits neurosteroid synthesis and potentially improves the course of hepatic encephalopathy (HE). This study aimed to investigate the effects of FIN on brain oxidative stress and acetylcholinesterase (AchE) activity in acute thioacetamide-induced HE in rats. Male Wistar rats were divided into groups: 1. control; 2. thioacetamide-treated group (TAA; 900 mg/kg); 3. finasteride...

A new genus and species of characid fish is described from rio Braço Norte, a tributary of rio Teles Pires, Tapajós basin, Mato Groso, Brazil. The new taxa can be diagnosed from the remaining characids by a unique combination of characters that includes the presence of a single row of relatively compressed premaxillary teeth, large teeth with four to nine cusps on premaxillary and dentary, abse...
