Amounts of conjugated linoleic acid (CLA) in German foods and evaluation of daily intake 总被引:10,自引:0,他引:10
The quantities of the biologically active isomer of conjugated linoleic acid (CLA) – C18:2 c9t11 – in 139 German foods were
analysed by capillary gas chromatography (results are given as a % of all identified fatty acid methyl esters). The CLA content
ranged from 0.40% (Gouda) to 1.70% (Jurassic cheese, Old Emmentaler) in dairy products, from 0.11% (rabbit) to 1.20% (lamb)
in meat, and from 0.01% (pike-perch) to 0.09% (carp) in fish. CLA could be detected in neither vegetable fats or oils nor
in margarines (CLA <0.01%). Crisps, chocolates, cakes and pastries, and other foods have only a negligible CLA content. The
average estimated CLA intake in Germany was calculated to be 0.35g CLA/day for women and 0.43g CLA/day for men.

沈84块高凝油藏水淹层测井评价参数及其应用 总被引:5,自引:0,他引:5
针对辽河沈84块沙三段下部高含水期高凝油藏储层水淹状况和特征,依据灰色系统油田开发分析方法及准则,利用测井、钻井取心、试油及有关地质资料,匹配、拟合和提取参数,分别以其特征性参数对高含水期油藏岩性、物性和水淹状况进行统计,采用正态统计特征值建立测井评价参数标准,以其准确率和分辨率自动组合放大,建立测井评价参数标准的权系数。通过该区沙三下的174口井高凝油藏水淹层测井评价参数研究的分析解释,划分出砂砾岩、含砾砂岩、中粗砂岩、细砂岩、粉砂岩和泥岩等岩性剖面,评价解释了不同类型的储层以及不同物性的油层、弱水淹层、中水淹层、强水淹层及水层,阐明了沈84块沙三下高凝油藏水淹状况及剩余油纵向分布规律。 相似文献

Andreas Pierratos Michaelene Ouwendyk Robert Franceur 《Hemodialysis international. International Symposium on Home Hemodialysis》1997,1(1):32-35
In order to provide a highly efficient, long-duration form of hemodialysis, we developed nocturnal hemodialysis. Patients were dialyzed nightly at home for 8 – 10 hours, 6 – 7 nights/week. We kept the dialysate flow at 100 mL/min and the blood flow at 250 – 300 mL/min. Patients were monitored remotely from the hospital through a computer connection. An internal jugular line was used as an access. We have trained 12 patients over 30 months and have accumulated 160 patient-months worth of data. The patients tolerated the dialysis very well and slept through the night. There was a significant improvement in their sense of well-being. Nightly Kt/V was 0.99. Weekly removal of phosphate was two times as high and β 2 -microglobulin four times as high as conventional hemodialysis. All patients have discontinued their phosphate binders and have increased their dietary phosphate and protein intake. Hypertension was controlled with fewer medications, and erythropoietin dosages decreased. Complications were infrequent and included catheter occlusion and infections. Reusing the dialyzers decreased the cost of the treatment to levels similar to continuous ambulatory peritoneal dialysis. Nocturnal hemodialysis represents a viable dialysis modality that combines high quality, low cost, and excellent tolerance. 相似文献

A demonstrative study for the wind and solar hybrid power system 总被引:1,自引:0,他引:1
In March 1995, a small scale wind and solar hybrid power system was installed at Ashikaga Institute of Technology. Until now, the authors have acquired the data of the output of the hybrid power plant along with wind speed, wind direction, and the solar radiation, in order to demonstrate a complementary relationship between solar energy and wind energy.After nine months operation of the system, the authors confirmed that there exists a complementary relationship between solar energy and wind energy. We also found, however, that the power output by wind does not have much prospect compared to that by solar cell especially in summer season in Ashikaga area. 相似文献

During the day, there are considerable variations in the climatic factors prevailing in these regions. This is especially so during the 24-hour daily cycle of the long, hot and dry summer (mid-May to midOctober). Such climatic conditions have had a considerable impact on the daily living pattern of family life in the same season, particularly in the urban areas. During the same 24-hour cycle, they have compelled the inhabitants to shift their living activities both vertically in section and horizontally in plan; they do this in pursuit of more acceptable, if not, desirable internal thermal environmental ambience. 相似文献
