background hydatidosis is an infectious disease resulting from the development of the larval form of the parasite echinococcus granulosus in humans. the invasion of the chest wall by echinococcosis is rarely described. methods the current study reported all cases of chest wall hydatidosis treated in the department of cardiothoracic surgery from january 1990 to december 2011. results the mean ag...

Two new species of Diplommatina from limestone hills on Borneo are described: D. heteropleura sp. nov., Sarawak (Malaysia) and stenoacron East Kalimantan (Indonesia). The first is uniquely identified among the Bornean by arrangement radial ribs: widely spaced all whorls except last 1.5, where they closely spaced; second belongs to a small group without ribs but larger than any them.

In this study, the effects of adding trapezoidal ribs to microchannel on functionalized multi-walled nano-tubes/water nanofluid heat transfer are examined. The dimensionless slip coefficient (0–0.1), Reynolds number (50–400) and Hartmann (0–20) considered as independent variables along with entropy generation output parameters. simulation outcomes confirm that addition ribs, one hand, increases...
