    Serous cystic neoplasm involving the pancreas and liver: an unusual clinical entity (1999)

    Notes: Abstract Serous cystic neoplasm of the pancreas is typically considered to represent a benign pancreatic neoplasm. We present a case where the tumor displayed unusually aggressive behavior with metastatic disease to the liver and pancreatic bed. Although serous cystic neoplasms should be considered a benign lesion and will be cured in most cases by surgical excision, the radiologist should be aware that on occasion they can exhibit aggressive behavior.

    Biochemical and energetic composition of bathyal echinoids and an asteroid, holothuroid and crinoid from the Bahamas (1990)

    Notes: Abstract The biochemical and energetic composition of body components of ten species of bathyal echinoids, and an asteroid, a holothuroid and a stalked crinoid were determined from individuals sampled from a variety of deep-water sites near the Bahamas (north Caribbean Sea) in October 1988. When compared with other studies of echinoderms, no geographic- or depth-related differences in biochemical or energetic composition were found. Body-wall tissues were composed primarily of skeletal material (mineral ash), but were comparatively high in organic material in the echinothuriid echinoids, and the asteroid and holothuroid. Gut tissues and pyloric cecae had high levels of lipid and protein, indicating their potential role in nutrient storage. Body-wall tissues were generally low in energy, but were highest in the echinoidsAraeosoma belli (7.7 kJ g−1 dry wt) andSperosoma antillense (8.0 kJ g−1 dry wt), the asteroidOphidiaster alexandri (8.9 kJ g−1 dry wt), and the holothuroidEostichopus regalis (13.1 kJ g−1 dry wt). Energy levels of gut and pyloric cecal tissues were two to three times higher than those of body-wall tissues. Total somatic tissue energy values varied greatly among species, ranging from 1.5 kJ in the echinoidAspidodiadema jacobyi to 142.1 kJ inE. regalis. As the bathyal echinoderms examined in this study occur in great abundance, they represent a significant reservoir of organic and inorganic materials and energy in deep-water benthic systems.

    Seasonal breeding aggregations in low-density populations of the bathyal echinoid Stylocidaris lineata (1992)

    Notes: Abstract Reproduction of bathyal cidaroid sea urchins was studied between 1985 and 1991 with the aid of a manned submersible in the northern Bahamas. During May 1988 and February 1990, discrete, single-species aggregations of Stylocidaris lineata containing 2 to 6 individuals were observed between 510 and 640 m depths. Reproductive conditions of isolated and aggregated individuals were determined histologically. In February, all individuals, regardless of their spatial distribution, contained developing gametes. During the May spawning season, most isolated individuals contained spent gonads with only relict gametes, whereas individuals in discrete aggregations mostly contained ripe gonads with mature or nearly-mature gametes. Aggregations were not observed during the autumn months, when gonads were spent or immature. These data suggest that bathyal cidaroids aggregate for reproduction. An in situ survey during May indicated that pairs of S. lineata are more common than larger clumps, but no more so than predicted by chance. Homosexual and heterosexual pairs occur at the relative frequencies predicted on the basis of sex ratio. We evaluated the need for reproductive aggregation by applying Denny's (1988) model that predicts downstream sperm concentration in a turbulent boundary layer. Flow parameters were measured with dye injected from the submersible, sperm-release rate was estimated in the laboratory, and the relationship between fertilization success and sperm concentration was determined in a laboratory dilution-experiment. The model predicted that, on smooth sandy bottoms at bathyal depths, sperm concentration should remain high enough to fertilize at least some eggs several meters directly downstream from a spawning male. Aggregation may facilitate spawning synchrony, increase gamete encounter probabilities, or cause gametes to be retained at high concentrations near the adults long enough for fertilization to occur.

    Notes: The arduous conditions to which hot section turbine components are subjected in service, dictate thesuperior physical and mechanical properties demanded of them. The demand for both hightemperature and creep resistance, and anisotropic property requirements of the components has leadto developments in alloy composition, component geometry and single, oriented grain structuredesign. The slim tolerances and high quality standards imposed on such design features, combinedwith the high production volume in industry means that component non-conformances to thecustomer specifications occur. The input variables contributing to crystallography non-conformancein single crystal production have been investigated with a view to defining optimum processparameters for the successful manufacture of single crystal investment cast components on anindustrial scale

    Notes: Sorption of ten different quantities of D2 within the porous coordination metal frameworkCu3(1,3,5-benzenetricarboxylate)2 were studied using neutron powder diffraction. D2 sorption in theporous material reached saturation (at 25 K) at an amount equivalent to ~6.5 wt. % H2. Rietveldanalyses revealed that at saturation there are two saturated small pore and three saturated large poresites, in addition to the primary site at the coordinatively unsaturated Cu. We reveal that the linkedbimodal pore system provides up to nine distinct sites for D2, at moderate D2 concentrations up tosaturation. Intermediate sites are attributed to local D2-D2 interaction within the confined porespaces. Within the small and large pores one, and two, intermediate sites are identified, respectively.The population of D2 at each site was found to affect the host lattice
