[Method] The wing venous blood of Donglan Black-bone chicken(silky feather and contour feather) was collected, and the total DNA was extracted. The 18 microsatellite loci were amplified by PCR technology, and the obtained gene fragments were scanned. The number of alleles(Na), number of effective alleles(Ne), heterozygosity(H) and polymorphism information content(PIC) were determined using Pop Gen 32 biological software to do cluster analysis of Guangxi indigenous chicken breeds. [Result] The18 microsatellite loci of Donglan black-bone chicken were found to be highly polymorphic. A total of 98 alleles were detected out from 80 Donglan black-bone chicken samples. The averages of Na, Ne, PIC and H per locus were 5.44, 2.78, 0.5382 and 0.596 3, respectively. A total of 93 and 98 alleles were detected out from silky- and contour-feather Donglan black-bone chickens, respectively. The averages of Ne per locus were 2.62 and 2.76, of PIC per locus were 0.508 8 and 0.539 8,of H per locus were 0.624 7 and 0.599 1, respectively. The results of cluster analysis showed that there was greater genetic distance between Donglan black-bone chicken and any of other Guangxi indigenous chicken breeds, including three yellow chicken, Xiayan chicken and Nandan Yao chicken, which was consistent with the breed evolution, geographical distribution and breeding history of Donglan black-bone chicken. [Conclusion] There are greater genetic variation and abundant genetic diversity in the conserved population of Donglan black-bone chicken, suggesting abundant genetic diversity and great breeding potential of Donglan black-bone chicken.展开更多

METHOD: Using a structured questionnaire, all patients with confirmed HCV infection were interviewed about the risk factors. RESULTS: Among the 250 patients studied, transfusion before 1993 was the primary risk factor in 26%, intravenous drug use setting in 9% and occupational exposure in health-care in 9%. Women were more likely to have a history of occupational exposure or transfusion before 1993 and less likely to undergo minor surgery. Known nosocomial risk factors (transfusion before 1993, dialysis) were responsible for 27% of infections, probable nosocomial factors (transfusions after 1992, minor surgery) for 14% and further 9% were occupationally acquired infections. CONCLUSION: A careful history investigation can identify a known or probable risk factor for HCV acquisition in 59% of patients with HCV infection. Preventive activities in Poland should focus on infection control measures in health-care setting.展开更多

This paper demonstrates that there are three complex, interrelated causes for this violence: foreign military intervention, Salafi-Jihadism and a utopian state founded upon faith and justice, i.e. a caliphate.展开更多

In this paper, it is shown how the SeaWinds scatterometer can be used to detect new sea ice at the very beginning of its growth. Taking advantage of the very good coverage of the East Greenland Sea by SeaWinds on board the QuikSCAT satellite it has been possible to detect the early stage of formation of the sea ice peninsula, named the Odden, and to monitor its evolution during March 2001. The early sea ice detection has been validated by using RADARSAT Synthetic Aperture Radar scenes. It is also shown that microwave radiometers, such as the Special Sensor Microwave Imager (SSM/I), which are used as standard sensors for sea ice monitoring, do not detect the very early stage of sea ice growth and lag behind new sea ice occurrence by about twelve to twenty four hours.展开更多

The special attention is given to the minority shareholders activism in the system of corporate governance. Some existing methods of abusing minority shareholders rights, made by joint-stock companies executives, are generalized. The recommendations for minority shareholder's rights protection are given. The necessity for the implementation of the stakeholders-oriented approach for the CSIS creation on the base of companies' security principles is substantiated.展开更多

The aim of this work is to demonstrate the agreement of production potential of grassland with the strategy of the CAP on the background of commodity milk production. This work is connected with randomly selected 1656 farms from the north-eastern part of the Lublin province remaining the dairy cattle. Source material for analysis was derived from the evaluation reports of dairy farms and the datas of Voivodeship Statistical Office. Taken the average annual milk production and surface of permanent grasslands, were divided into three groups of management direction: I- existing, II- integrated, III- productional In a separate II group of this management, three subgroups were identified dependent on the volume of milk production: A-(20-50), B-(50-100), C-(100-350) thousand of liters. In the studied farms the participation of grasslands in the structure of agriculture fanning lands was significantly higher than the average in the region as well as in the country. The largest research group accounted 49.5% of farms producing 20-50 thousand liters of milk with an average area of 21.23 ha and sustained an average of 9.8 cows. Large proportion of permanent grassland in the structure of agricultural lands and large stocking density per 100 ha of grasslands in northeast farms of Lublin province indicate significant intensification of feed production on the farmlands.展开更多

In analogy with experimental index EBI (European Blocking Index) for the Eastern Atlantic and Western Europe is proposed a new index ECBI (European Continental Blocking Index), which describes the blocking of zonal flow over the European continent. The obtained time series of the ECBI for the spring-summer seasons with the severe droughts in Ukraine were analyzed. Katz circulation index was used for the estimating of intensity of the meridional atmospheric processes during the same droughts. It is shown that there registered a high frequency of blocking processes which was accompanied by positive phases of ECBI and an increase in the meridional component of an atmospheric flow over the region of Europe. In years with droughts in average 60% consecutive pentads were with a positive value of ECBI, mostly in April to May. The absolute maximum duration of blocking was the 10 consecutive pentads and observed in 1963. The high positive values of the ECBI and Katz index were connected with strong anomalies in seasonal and monthly fields of wind over territory of Eastern Europe. A close relationship between the ECBI and the Katz index was obtained, which allowed to determine the critical value of the Katz index for the beginning of blocking situation,展开更多
