In a multi-board computer system, the volume allocated for heat removal is often a significant fraction of the total system volume. Cooling requirements can thus impact performance, reliability, cost, acoustic noise, and floorspace. This work addresses the volume costs or space requirements for removing heat with optimally designed finned heat sinks. Simple formulas applicable to both gas and l...

Brucella ceti is an emerging zoonotic pathogen that has been recovered from several species of cetaceans in the world's oceans over the past 20 yr. We report the recovery of B. ceti from a Sowerby's beaked whale (Mesoploden bidens) and a long-finned pilot whale (Globicehala melas). Recovery from the testis of a long-finned pilot whale provides further evidence of potential for B. ceti infection...

This paper presents the detailed design and analysis of an asymmetric fin tube condenser. And the heat transfer performance of the asymmetric fin tube condenser is simulated with the fluent software. Based on the simulation results, an optimal model of the asymmetric-finned tube condenser is designed. The actual model is experimentally studied on air conditioners and contrasted with the symmetr...

The Genome 10K project aims to sequence the genomes of 10,000 vertebrates, representing approximately one genome for each vertebrate genus. Since fishes (cartilaginous fishes, ray-finned fishes and lobe-finned fishes) represent more than 50% of extant vertebrates, it is planned to target 4,000 fish genomes. At present, nearly 60 fish genomes are being sequenced at various public funded labs, an...

Molecular evolutionary rates within two protistan and three metazoan taxa were estimated using divergence times derived from fossil records. The results indicate that the small-subunit rRNA sequences within Dasycladales (Chlorophyta) and Bacillariophyceae evolved at a rate approximately two to three times faster than that estimated within Echinodermata, Mollusca, and Actinistia-Tetrapoda. It wa...

We present a redescription of Megalocoelacanthus dobiei, a giant fossil coelacanth from Upper Cretaceous strata of North America. Megalocoelacanthus has been previously described on the basis of composite material that consisted of isolated elements. Consequently, many aspects of its anatomy have remained unknown as well as its phylogenetic relationships with other coelacanths. Previous studies...

Most marine mammals are hypothesized to routinely dive within their aerobic dive limit (ADL). Mammals that regularly perform deep, long-duration dives have locomotor muscles with elevated myoglobin concentrations that are composed of predominantly large, slow-twitch (Type I) fibers with low mitochondrial volume densities (V(mt)). These features contribute to extending ADL by increasing oxygen s...

Possessing large brains and complex behavioral patterns, cetaceans are believed to be highly intelligent. Their brains, which are the largest in the Animal Kingdom and have enormous gyrification compared with terrestrial mammals, have long been of scientific interest. Few studies, however, report total number of brain cells in cetaceans, and even fewer have used unbiased counting methods. In th...
