Minutiae are small distinguishing features found along every ridge flow, which make each friction ridge print unique. The most common friction ridge prints found at the crime scene are fingerprints; therefore, the most of the minutiae studies are focused exactly on this kind of prints. The authors believe that further examination and enlargement of the palm print database could result in better use of the palm prints for personal identification. We analyzed a total of 160 palm prints from 40 females and 40 males aged between 18 and 70 years from Slovakia. For the evaluation of the minutiae, the area of the hypothenar had to be marked out. The classification of the minutiae used for this study was based on a modified version of the classification system using the total of 13 types of minutiae. The frequency of every minutiae type was calculated and, using the chi-square test with Yates's correction, bilateral and sex differences were assessed. The relationship between the different types of minutiae was examined with Pearson's correlation test. During the initial phases of the identification process, the focus should be on the least common types of minutiae (Y or M and return), which were found not to correlate; thus, their mutual occurrence is random (e.g., overlap—Y or M, crossbar—return, or Y or M—dock). The results of the present study show which specific minutiae types are the most suitable for personal identification. These findings may be beneficial in more effective outcome of the identification process. 相似文献

This paper develops a neo-Gramscian conceptual framework in order to examine the ideological constructs and political dynamics that frame the day-to-day workings of the certification-based Fairtrade initiative. To accomplish this goal, the paper resorts to the notion of a ‘comprehensive concept of control’, which accounts for the main ideological elements that constitute the Fairtrade vision of the world. The analysis of these imaginaries is complemented with an examination of the concrete ways in which they have been institutionalized in the Fairtrade system and the specific power relations between class fractions they promote. This is followed by an exploration of the way in which Fairtrade articulates the contradictory interests of a variety of class fractions, bringing them together under the shared objective of advancing the situation of small producers and workers in the global South. The paper finishes with a reflection on the main limitations inherent to Fairtrade’s concept of control and the political dynamics it entails. 相似文献

为了探讨抗须癣毛癣菌感染新的治疗途径,从患须癣毛癣菌病兔自然恢复皮肤分离了1株细菌,经16S rDNA基因比对,并结合菌落形态进行了鉴定,通过体内外试验测定其对须癣毛癣菌的拮抗作用。结果显示,分离株能在营养琼脂培养基生长,菌落为皱褶圆形,菌体呈杆状,革兰染色阳性,基因序列分析与GenBank中的枯草芽孢杆菌相似率为99.8%,该分离株被鉴定为枯草芽孢杆菌。抗菌谱分析显示,分离株对须癣毛癣菌能形成抑菌圈,对白色念珠菌、平滑念珠菌、热带念珠菌、烟曲霉菌、黄曲霉菌没有抑制作用。该分离株与须癣毛癣菌混合培养,能明显抑制须癣毛癣菌生长。在皮肤涂抹试验中,该分离株能逆转由须癣毛癣菌引起的皮肤病变。本试验证实了分离的枯草芽孢杆菌对须癣毛癣菌有明显的拮抗作用。 相似文献

This paper draws on recent research examining feminist and everyday geopolitics to focus on the relatively neglected domestic sphere as a space where geopolitical events like the Falklands/Malvinas war are learnt, (re)produced, remembered and contested by young people. It presents qualitative data drawn from interviews with young people from Argentina (Río Gallegos) and the Falkland Islands (Stanley), locations with intimate connections to the 1982 war. It argues that research in domestic environments that engages the familial relations, objects and practices that embody geopolitical pasts can help make sense of how young people (are able to) express geopolitical agency. 相似文献

为了确定猪生殖与呼吸综合征病毒GP5蛋白A、B抗原表位之间的相互关系和对免疫的影响,应用PCR方法扩增出A、B抗原表位基因并分别克隆于原核和真核表达载体中。原核重组质粒表达的重组蛋白经Western-blotting检测证明,该重组蛋白具有良好的抗原性。将重组蛋白和真核表达质粒免疫小鼠,前者可诱导产生针对PRRSV的特异性ELISA抗体,但是此抗体没有中和活性;后者不能诱导免疫小鼠产生PRRSV特异性抗体。结果表明,中和抗体的产生不但与A、B表位的空间构象有很大的关系,如果蛋白质分子质量过小也不能诱导机体产生有效的免疫反应。 相似文献

幼年牦牛松果体的光镜和电镜观察 总被引:1,自引:0,他引:1
利用光镜和电镜技术对幼年牦牛松果体的组织形态结构特征进行了研究。结果表明,光镜下,幼年牦牛松果体由松果体细胞、少量的神经胶质细胞、毛细血管和神经等组成。电镜下,松果体细胞的电子致密度低,细胞质内含有丰富的线粒体、粗面内质网、滑面内质网、高尔基复合体、微管、微丝和核糖体,典型异质细胞器突触带呈球形,多位于质膜附近。神经胶质细胞内的线粒体丰富,胞体突起呈球形膨大伸入到松果体细胞之间。松果体细胞以及神经胶质细胞间均存在突触和连接复合体。牦牛松果体内的毛细血管为连续型,远腹侧血管周围可见色素细胞。 相似文献
