Phylogenetic relationships of 12 Penaeoidea shrimp species deduced from mitochondrial DNA sequences

DNA sequences of an 847 bp fragment of mitochondrial cytochrome oxidase subunit I (COI) gene and a 514 bp fragment of 16s rRNA gene were determined to examine the phylogenetic relationships of 12 Penaeoidea shrimp species (Penaeus chinensis, Penaeus japon

Effects of gelatin on mechanical properties of hydroxyapatite-gelatin nano-composltes

A biomimetic reactor has been developed to synthesize hydroxyapatite- gelatin (HAP-GEL) nanocomposites that mimic ultra-structures of natural bone. We hypothesize that in the reactor, gelatin concentration controls morphology and packing structures of HAP crystals. To test the hypothesis, three types of mechanical tests were conducted, including nanoindentation, compression, and fracture tests. Nanoindentation tests in conjunction with computer modeling were used to assess effects on gelatin-induced microstructures of HAP. The results showed that increasing gelatin content increased both the plane strain modulus and the fracture toughness. The gelatin appeared to shorten the HAP crystal distance, which consolidated the internal structure of the composite and made the material more rigid. The fracture toughness KIC increased partially due to the effect of fiber bridging between gelatin molecules. The highest fracture toughness (1.12 MPa·1/2) was equivalent to that of pure hydroxyapatite. The compressive strength of the HAP-GEL (107.7±26.8 MPa) was, however, less sensitive to microstructural changes and was within the range of natural cortical bone (human 170 MPa, pig: 100 MPa). The compression strength was dominated by void inclusions while the nanoindentation response reflected ultra-structural arrangement of the crystals. The gelatin concentration is likely to modify crystal arrangement as demonstrated in TEM experiments but not void distribution at macroscopic levels. © 2006 Materials Research Society.

Isolation of Salmonella agona (4, 12:f, g, 5:-) from commercial frozen boiled clam meat

Details are given of the morphological, biochemical and serological characteristics of a specimen of Salmonella agona isolated from a sample of frozen boiled clam meat (Villorita cyprinoides) processed in a factory at Cochin. Possible association of this serotype with human salmonellosis is considered briefly.

笼养大紫胸鹦鹉取食活动

笼养大紫胸鹦鹉取食活动占观察时间的14.51%，是其主要行为活动之一。日取食活动呈现早（7：00#approx#10：00）、晚（15：00#approx#19：00）2个明显的高峰。每日取食（32.12+ -14.28）次，累计日取食时间（153.23+ -73.11）min。每次取食的时间平均为（5.29+ -1.06）min。两性和成幼间以及不同时期的取食活动有一定的差异。在整个取食过程中，除拾取（45.47%）和咀嚼（46.49%）两种取食行为外，还有身体护理（2.51%）、运动（3.59%）、静栖（1.72%）、攻击（0.12%）、求偶（0.1%）等活动出现。逐步回归分析表明：影响大紫胸鹦鹉成鸟取食活动的主要因素是生物学因素；5月龄以前幼鸟的取食行为除受生物学因素的影响外，还与温度有一定的关系。
