化学污染可能导致肥胖     

《海洋世界》2008,(10):9-9

污染又添新罪行——这次它成为肥胖的“推手”!一项新的研究结果表明，那些在出生前接触过化学制品的婴儿。出生后便很可能朝肥胖方向发展。这项研究首次将胎儿在子宫内受到的化学污染与世界性的健康问题——肥胖联系在一起。遗传的差异赋予不同的人不同的代谢途径，使一些人的体重更容易飙升。  相似文献   

Chemical study of limestone and clay for cement manufacturing in Darukhula,Nizampur District,Nowshera, North West Frontier Province （N.W.F.P.）, Pakistan     

Khurshid Ali  ;Noor-ul-Amin  ;M.Tahir Shah 《中国地球化学学报》2008,27(3):242-248

Limestone and clay samples were collected from Darukhula and adjoining areas of the Nizampur District Nowshera, N.W.EE, Pakistan, and analyzed for different parameters in order to search for new reserves of suitable material for the manufacture of different types of cements in N.W.F.P. It was found that the area under study contains three types of limestones, including high grade limestone, Darukhula limestone and siliceous limestone, which contain 53%, 49.03% and 45.19% CaO, respectively, and three types of clay, including maroon color, yellow to yel- lowish-green color and green color clay containing 57.76%, 65.47% and 61.24% SiO2, respectively. Chemical analysis of the limestone and clay samples collected from the deposits in the area under study showed that all the elements found in these samples are within the range of permissible limits for the production of high-strength Portland cement, sulphate resisting cement and white cement. This paper covers the detailed version of the potential raw material deposits at Darukhula and adjoining areas of the Nizampur District.  相似文献

Rheological and Structural Properties of Sea Cucumber Stichopus japonicus During Heat Treatment   总被引：6，自引：0，他引：6  

GAO Xin XUE Dongmei ZHANG Zhaohui XU Jiachao XUE Changhu 《中国海洋大学学报(英文版)》2005,4(3):244-247

Changes in tissue structure, rheological properties and water content of raw and heated sea cucumber meat were studied. Sea cucumber Stichopus japonicus was heated at 25℃, 70℃ and 100℃ water for 5 min. The structural changes were observed using a light microscope and the rheological parameters （rupture strength, adhesive strength and deformation） determined using a texture meter. Microscopic photograph revealed that the structural change of heated meat was greater than that of raw meat. The rupture strength, adhesive strength and deformation of raw meat were smaller than those of the heated meat. Meanwhile, rheological parameters showed positive correlation with heating temperature. These changes are mainly caused by thermal denaturation and gelatinization of collagen during heating. These changes were also evidenced in observations using a light microscope and differential scanning calorimetry.  相似文献
