The Dongcaohe ophiolite from the North Qilian Moun-tains: A fossil oceanic crust of the Paleo-Qilian ocean

Chinese Science Bulletin 2007年第17期52卷 2390-2401页

作者： Chien-Yuan TSENG Huai-Jen YANG Houng-Yi YANG LIU DunYi ching-lang tsai WU HanQuan ZUO GuoChao Department of Earth Sciences Cheng Kung University Tainan 701 Taiwan China Beijing SHRIMP Centre Institute of Geology Chinese Academy of Geological Sciences Beijing 100037 China Xi'an institute of Geology and Mineral Resources Xi'an 710054 China Gansu Bureau of Geology and Mineral Resources Lanzhou 730000 China

The Dongcaohe ophiolite, located at the south of the North Qilian subduction complexes, is a tectonic block with an exposed area of about 3 km×6 km. It consists of an intrusive section overlain by an ex- trusive section. The lower part of the intrusive section consists of cyclic layers of cumulate dunites, troctolites, anorthosites, anorthositic gabbros, and gabbros with small discordant dunite and troctolite bodies. This layered sequence grades upward to isotropic gabbros and gabbronorites, which are overlain by the extrusive sequence of diabasic sheeted dikes and basaltic lavas. The overall mineral crystallization sequence was olivine±Cr-spinel, plagioclase, clinopyroxene, orthopyroxene, and Fe-Ti oxides. The Cr-spinel (Mg#: 42-66, Cr#: 41-57) in these layered cumulates and present-day abyssal peridotites have similar compositions. Also, the compositional variations of the plagioclase and cli- nopyroxene in the intrusive section reflect crystallization from melts compositionally similar to the present-day ocean basalts. Moreover, the rare earth element (REE) and multi-element distribution pat- terns of the intrusive and extrusive lithologies in the Dongcaohe ophiolite are consistent with crystal- lization of mid-ocean ridge basalts. The zircon grains separated from the gabbronorite have an SHRIMP average 206Pb/238U weighted age of 497 ± 7 Ma, which is considered as the tectonic emplacement age of the Dongcaohe ophiolite. The field occurrence, mineral and whole-rock compositions indicate that the Dongcaohe ophiolite represents a well-persevered oceanic crustal fragment composed of a complete oceanic crustal section of layered cumulates at bottom upgrading through isotropic cumulates to sheeted dikes and lava flows.

A new design of groundwater sampling device and its application

引用

Journal of Environmental Sciences 2005年第5期17卷 838-841页

作者： Yih-Jin tsai Ming-ching T. Kuo Department of Environmental Resources Engineering Diwan College of ManagementDepartment of Mineral and Petroleum Engineering "National" Cheng Kung University No. 87-1 Nansh Li Madou Tainan Taiwan ChinaTainan Taiwan China

Compounds in the atmosphere contaminate samples of groundwater. An inexpensive and simple method for collecting groundwater samples is developed to prevent contamination when the background concentration of contaminants is high. This new design of groundwater sampling device involves a glass sampling bottle with a Teflon-lined valve at each end. A cleaned and dried sampling bottle was connected to a low flow-rate peristaltic pump with Teflon tubing and was filled with water. No headspace volume was remained in the sampling bottle. The sample bottle was then packed in a PVC bag to prevent the target component from infiltrating into the water sample through the valves. In this study, groundwater was sampled at six wells using both the conventional method and the improved method. The analysis of trichlorofluoromethane（ CFC-11 ） concentrations at these six wells indicates that all the groundwater samples obtained by the conventional sampling method were contaminated by CFC-11 from the atmosphere. The improved sampling method greatly eliminated the problems of contamination, preservation and quantitative analysis of natural water.

New Challenges for Biological Text-Mining in the Next Decade

Journal of Computer Science & Technology 2010年第1期25卷 169-178,F0003页

作者： Yen-ching Chang Richard Tzong-Han tsai Wen-Lian Hsu Institute of Information Science "Academia Sinica" Department of Computer Science and Engineering Yuan Ze University Department of Computer Science "National Tsing-Hua University"

The massive flow of scholarly publications from traditional paper journals to online outlets has benefited biologists because of its ease to access. However, due to the sheer volume of available biological literature, researchers are finding it increasingly difficult to locate needed information. As a result, recent biology contests, notably JNLPBA and BioCreAtIvE, have focused on evaluating various methods in which the literature may be navigated. Among these methods, text-mining technology has shown the most promise. With recent advances in text-mining technology and the fact that publishers are now making the full texts of articles available in XML format, TMSs can be adapted to accelerate literature curation, maintain the integrity of information, and ensure proper linkage of data to other resources. Even so, several new challenges have emerged in relation to full text analysis, life-science terminology, complex relation extraction, and information fusion. These challenges must be overcome in order for text-mining to be more effective. In this paper, we identify the challenges, discuss how they might be overcome, and consider the resources that may be helpful in achieving that goal.

作者： ching-Yi Lin Cheng-Yu tsai Shyh-Hsiang Lin Graduate Institute of Nutrition and Health Sciences Taipei Medical University (110) 250 Wu-Hsing Street Taipei Taiwan China

AIM: To assess the effects of soy protein, isoflavone, and saponin on liver and blood lipid in rats that consumed high-cholesterol ***: High-cholesterol diets (1%) with or without soy material were fed to 6-wk-old male Sprague-Dawley rats for 8 wk. Blood lipids, liver lipids, glutamic oxaloacetic transaminase (GOT), and glutamic pyruvic transaminase (GPT) levels were measured. The in vitro bile acid-binding ability of soy materials was ***: The results of in vitro studies showed that soy protein isolate had a significantly higher bile acid-binding ability (8.4±0.8%) than soy saponin (3.1±0.7%) and isoflavone (1.3±0.4%, P＜0.05). On the other hand, at the end of the experimental period, rats that consumed soy protein diets had lower GOT and GPT levels than rats that consumed casein under high-cholesterol *** that consumed soy protein also had lower total cholesterol (TC) levels in the liver than those that consumed casein under high-cholesterol diets. Rats that consumed the soy protein diet containing both saponin and isoflavone had lower hepatic TC level than those that consumed the soy protein diet without isoflavone *** effect of different types of proteins on triglyceride was not ***: Consumption of soy provided benefits to control lipid levels under high-cholesterol dieting conditions in this rat model of hypercholesterolemia. The major component that reduced hepatic TC was not saponin, but possibly isoflavone.

AIM： To investigate the effects of fermented soy milk powder on the antioxidative status and lipid metabolism in the livers of CCh-injected rats. METHODS： Forty-five healthy male Sprague-Dawley rats were randomly assigned to five groups according to five different diets： control （AIN-76）, AIN-76＋high- dose fermented soy milk powder, AIN-76＋low-dose fermented soy milk powder, AIN-76＋high-dose milk yogurt powder and AIN-76＋low-dose milk yogurt powder. The experiment lasted for 8 wk. After 4 wk, all the rats received intraperitoneal administration of CCh （0.2 mL/100 g body weight） every week. Total cholesterol （TC）, triglyceride （TG）, TBARS, ALP, and antioxidative enzymes in the liver were evaluated. RESULTS： There was also no significant difference in TBARS and antioxidative enzymes in the liver. TC and TG in the groups fed with fermented soy milk powder were generally lower than those fed with casein powder. CONCLUSION： Consumption of fermented soy milk was positive in lowering total cholesterol and TG accumulation in the liver under CCh-induced oxidative
