In this paper we report calculation of the nuclear magnetic shielding constant using extended coupled cluster response approach. We present the results for the HF, BH, CO and N 2 molecules. These results show importance of correlation corrections for the shielding constant.

The New Zealand blackfoot abalone, Haliotis iris Gmelin, is among the few gastropods that precipitate both calcite and aragonite in their shells. The location, composition, and thickness of these mineral layers may affect color, luster, and strength of the shell, which is locally important in jewelry manufacture. Skeletal mineralogy and shell structure of H. iris from three southern New Zealand...

The Pacific oyster, Crassostrea gigas , is widely distributed and substantially important to shellfish cultivation. Oysters with melanin-colored shells soft parts are increasingly popular of high economic value. However, the distribution synthesis melanin in C. remains unclear there have been only few relevant studies on it. In this study, transmission electron microscopy (TEM) was used observe...

OBJECTIVE The reconstruction of a defect involving complex cartilaginous structures such as the ear and nose is a difficult problem. Cartilage donor sites are limited, and the shaping of an ear or nose is dependent upon the surgeon's skills and experience. In this report, we propose to use resorbable plates that can be shaped to serve as a template for cartilage healing. METHODS A shell compo...

the effect of γ-al2o3 nanoparticles on heat transfer rate, baffle spacing and pressure drop in the shell side of small shell and tube heat exchangers was investigated numerically under turbulent regime. γ-al2o3-water nanofluids and pure water were used in the shell side and the tube side of heat exchangers, respectively. since the properties of γ-al2o3-water nanofluids were variable, they were ...
