2PHYSIOLOGICAL INHIBITORY EFFECT OF OCS IN ARACHIDONIC ACID-RICH PARIETOCHLORIS INCISA (TREBOUXIOPHYCEAE, CHLOROPHYTA)显示文摘Parietochloris incisa is an arachidonic acid rich snow green alga. The main physiological profiles, such as ash free dry weight (AFDW), chlorophyll, carotenoid, protein and total fatty acids (TFA), in this alga exposed to old culture supernatant (OCS) at the decline phase or its crude ethyl acetate extracts (CEAE) were investigated by using tubular photobioreactors of different diameters. Results showed that both OCS and CEAE had strong inhibitory effect on the above physiological parameters. The longer the culture was exposed to OCS and the more CEAE were added into the algal culture, the more the above physiological properties were inhibited. Arachidonic acid (AA), the dominant component of fatty acids in this alga, was also seriously inhibited with respect to total TFA, AFDW of cell mass, or culture volume, due to a probable reduction of enzymes activities catalyzing chain elongation from C18:1ω9 to AA. These results incontestably evidenced that some CEAE dissolving substances existing in OCS, like auto inhibitors, inhibited P. incisa growth through feedback. Hence, any efficient removal of auto inhibitors from algal culture to decrease their bioactivity could be good for maximal production of desired products like AA.刘建国 张成武 Zvi Cohen Amos Richmond 2002Chinese Journal of Oceanology and Limnology2002,20,3:7
3Comparison of PBDE congener profiles and concentration levels in human specimens from China and the US and identification of human exposure sources显示文摘In an effort to investigate the status of human exposure to PBDEs in China,available monitoring data in human specimens(including breast milk,serums,and blood) was collected from the general population as well as specific groups that are occupationally exposed.PBDEs exposure profiles and concentration levels were compared with their counterparts in the United States of America.It was found that PBDE burdens in general Chinese population are one order lower and have different congener profiles from that in the US,showing higher percentages of BDE-28 or BDE-153 in human specimens from China.Workers and residents in electronic wastes recycling regions or areas of commercial PBDE manufacturing have the highest PBDE exposure levels reported worldwide,which are close or higher than the exposure levels of the general population in the US. Highly brominated congeners,such as BDE-207 and 209,are among the major PBDE congeners,and BDE-209 has the highest percentage(above 50%) for all occupational populations studied.Principal components analysis(PCA) demonstrates that the exposure of the general population in the US is closely related to penta-BDE while the human burden in China is not.The PBDE in indoor air(gas phase) in the US is highly correlated with the PBDE burden in the general population in the US,indicating a major exposure pathway.For the occupationally exposed populations in China,the congener profiles are closely related to the commercial deca-BDE products.Examination of exposure profiles for general and occupational populations in China suggests that it is essential to include more highly brominated congeners,such as BDE-207 and 209,in future human exposure studies,in order to assess the real burdens and profiles of PBDEs exposure in China.Strict pollution prevention and occupational protection procedures are in need in China to avoid the PBDE contamination problem that has occurred in the US.SHE JianWen 1,SHE YiFan 2 &SONG WenLu 2 1 Biochemistry Section,Environmental Health Laboratory Branch,California Department of Public Health,Richmond,CA 94804,USA 2Chemistry Section,Food and Drug Laboratory Branch,California Department of Public Health,Richmond,CA 94804,USA 2010Science China Chemistry2010,53,5:5
4IPOP:体验偏好理论显示文摘IPOP理论与实践来源自20世纪90年代至今的华盛顿史密森尼博物馆的观众调查,包括基础性的观察以及深入访谈,这些数据构成了一个具有长远意义的数据库。此研究的主要目的在于:能够更好地服务博物馆观众,即给观众带来高于平均水平的独特、有意义以及值得纪念的博物馆体验。在16年间的无数研究和访谈中,观众对于史密森尼博物馆展览的反应按照他们的原始兴趣可以被分为四个类型:I=观点,P=人,O=物,P=身体。事实证明展览若能引起四类观众的强烈共鸣,那么该展览在观众层面上是成功的。Andrew J.Pekarik James B.Schreiber Nadine Hanemann Kelly Richmond Barbara Mogel 王思怡 2017中国博物馆2017,,2:5

8DEVELOPMENT AND PRODUCTION OF FeAl BASED INTERMET ALLICALLOYS显示文摘Intermetallic materials have long been considered as potential candidates for high temperature applications due to their high strength/weight ratio, oxidation resistance, and corrosion resistance. The recent alloy design approaches undertaken by many researchers around the world allowed design of intermetallics for high strength application. Environmental embrittlement, solidification porosity, and low ductility of FeAl alloys necessitated innovative ways of processing FeAl sheets based on powder metallurgical route as opposed to an ingot route. Excellent sheets of FeAl have been processed by roll compaction followed by sintering technique using water atomized FeAl powder. Gas atomized FeAl powder was used to obtain sheets of FeAl by tape casting technique. Plasma spray technique was employed to obtain coating of FeAl alloy.S.D.Deevi, M.R.Hajaligol, A.Cliff Lilly and G.S.Fleischhauer Research Center, Philip Morris USA, 4201 Commerce Road, Richmond, VA 23234, U.S.A. 1999中国有色金属学会会刊:英文版1999,9,S1:2
9Processing technologies for gold-telluride ores显示文摘Gold telluride ores are important gold refractory ores due to the presence of sulfides and other gangue materials.The classification and main physical properties of gold telluride ores were described,and possible treatment methods including flotation,leaching,and oxida-tion were reviewed.The results show that flotation procedures are much easier for gold tellurides compared to other refractory gold-bearing ores.For the conventional cyanide leaching process,pretreatment such as oxidation is required to achieve high gold recovery.Roasting is a relatively simple but not environment-friendly method;bio-oxidation technology seems to be more suitable for the oxidation of flotation concentrate.Other treatment methods involve cyanide leaching,thiourea leaching,ammoniacal thiosulfate leaching,carbon-in-pulp,and resin-in-pulp,all of which are less commonly utilized.Jian Zhang Yao Zhang William Richmond Hai-peng Wang 2010International Journal of Minerals,Metallurgy and Materials2010,17,1:2
