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...

prostatic intra-epithelial neoplasia (pin) is considered a precursor of invasive carcinoma, characterized by proliferation and anaplasia of cells lining prostatic ducts and acini. in this study, we applied the pin grading system on one-hundred cases of prostatic carcinoma and one-hundred cases of benign prostatic hyperplasia, then compared the results. 74% of prostatic carcinoma and 51 % of pro...

Miniaturization of assays is an important objective in Ultra-HTS. One of the major obstacles has been to find fluid handling systems capable of reliably and accurately delivering between 2 and 200 nl of test compound to assay plates. New methods of forming pins, placing slots in the pins, and hydrophobic coatings bonded onto the pins solve many of the problems encountered by early pin tools. Un...

Based on specimens from the Lower Cretaceous Tlayua Formation of Mexico, we describe a new genus and species of Halecomorphi, Cipactlichthysscutatus gen. et sp. nov, which exhibits several diagnostic characters such as the dermal bones and the scales with ganoin and highly ornamented by numerous tubercles and ridges; parietal slightly longer than wide with approximately the same length as the f...

BACKGROUND The optimal treatment for femoral fractures in children is controversial. The purpose of this study was to compare the results of Rush pin fixation with those of conservative treatment, and to evaluate the sequels of growth plate injury by internal fixation. METHODS Eighteen femoral shaft fractures in 17 children who had concomitant head injury or multiple traumas were treated surg...
