Abstract: The research is focused on the detection and transfer of iron traces left by iron items on clothing and human skin. The method is based on the formation of colored complexes between ferrous ions and five synthesized, mostly new triazines. Iron traces originally were left by iron rings on slightly wetted (artificial sweat) cotton fabrics and subsequently transferred to a separate textile substrate. Prior to the use of trazines the contact spots were treated with a new inorganic reducing agent (Sn2+) to reduce Fe3+ to Fe2+. The method is sensitive to detect iron traces on wetted canvas after 10 min contact with iron items. More spectacular results were obtained for traces left on human palm even after very short contact (10 sec). The new iron‐trace‐transfer method eliminated the contact of triazines solutions with human skin. Transmission visible spectra of Fe(II)–triazine complexes were determined.  相似文献

当今世界,现代性把我们带入到了全新而纷乱的情境之中,其自身不自觉地附带产生了大量的副产品,它们作为现代性引致的后果具有高度的危险性,严重威胁着人类的安全。我们正在际遇着风险社会的到来。它从政治、经济、文化和社会诸方面对我国夺取全面建设小康社会伟大目标新胜利提出了警示。我们必须坚持以科学发展观为重要指导方针和重大战略思想,正视风险的客观存在,构建应对风险的各种机制,改写风险,才能最终迈进全面小康。  相似文献

性别是个体识别的主要生物学指标之一,是法医学鉴定不明骨骼残骸的重要初始步骤。枕骨大孔因其解剖学位置的隐匿性、形态学的稳定性、性别与种族的差异性成为法医学性别判定的研究热点,其中枕骨大孔面积是枕骨大孔区域中进行性别判定准确率较高的指标之一。本文以枕骨大孔面积为主要研究对象,就国外学者通过干颅骨样本、CT影像、CBCT影像测量枕骨大孔面积判定性别的方法进行总结,对国内应用枕骨大孔面积进行性别判定研究提供参考。  相似文献

Abstract

The aim of this article is to explain the internal conditions of military security in a non-European context. It utilises securitisation as the theoretical perspective and investigates Iranian and Indonesian case studies to explore how the perception of internal threats and vulnerabilities determines the approaches to military security. It begins with a reiteration of securitisation theory assumptions, followed by clarifying the understanding of security in non-Western contexts. The case studies focus on the conditions which facilitate securitisation, including the nature of securitising actors, assumed concepts of security, and securitisation processes and their outcomes. The analysis indicates a necessity for several alterations in securitisation theory to realise its full potential. Civil–military relations in Asian states differ from those in the West, as both Iran and Indonesia show a high degree of military involvement in political affairs. Military security also becomes securitised as a result of internal political rivalries. The perception of threats is a tool in the struggle to extend the capabilities of security agencies or retain influences.  相似文献

ABSTRACT

This article concerns structural funding for Polish cultural heritage for the years 2007–13, focusing on the largest operational program, “Infrastructure and Environment,” financed by the European Regional Development Fund. It presents the results of empirical research based on a questionnaire study of a specifically selected group of projects funded under this program. The objective of the study was to analyze the outcomes of this funding upon completion of the financial perspective, presenting tangible and intangible results as well as potential external effects. The empirical data allowed the development of conclusions and recommendations, stressing the importance of the continuing improvement and development of the funding scheme.  相似文献

Building on Ahmad ibn Yusuf b. al-Qadi al-Timbuktawi's treatise entitled Hatk al-Sitr Amma Alayhi Sudani Tunis min al-Kufr (Piercing the Veil: Being an Account of the Infidel Religions of the Blacks of Tunis) this paper examines the implications of the Hausa non-Muslim Bori cult practice in Ottoman Tunis on enslaved West Africans' retentions of religious and family values from their original homelands. Specifically, the paper traces and analyses the evolution of Bori cult practice in the Tunisian milieu and places it in its proper historical and diasporic contexts. To this end, the paper goes beyond questions that are not central to al-Timbuktawi's condemnation of the enslaved West African community of Tunis, but which nonetheless attracts the attention of scholars interested in the diasporic and historical significance of Bori cult practice in the Maghreb.  相似文献

This article shows that templates are not only crucial for the ways in which journalists construct or structure the media discourse but also for how they perceive themselves and others in the process of journalistic practice. A Critical Discourse Analysis of interviews with Polish journalists on their practices related to reporting migration – a topic largely discarded and ignored by the Polish media – shows that the construction of practice in the journalistic field constantly negotiates the contradiction between “knowing-it-all”, a key element of the template of journalistic habitus/identity, and the frequent lack of experience or limited knowledge of practice and of journalistic work. The analysis reveals that, while often using a discursive strategy of pre-legitimation, journalists enact templates that blur the boundaries between discourses about experiences of journalistic work and imaginaries or scenarios of actions they would only potentially undertake. Journalistic discourses of practice thereby become increasingly displaced, that is, they run along similar templates of discourse of/about quasi-universalised ethics and values of journalism almost irrespective of media organisations of the informants. By the same token, it is emphasised that, rather than being limited by the ideologies and powers of media organisations, agency seems to be often self-constrained by journalists in their self-entrapment in values, templates and imaginaries of journalism.  相似文献

为评价新三嗪类抗球虫药物纳川珠利的安全性,选用100只昆明小鼠,连续30d分别灌服4.8、19.2、76.8mg/kg的药物,以纯水和空白溶剂为对照,通过临床观察、血液学分析、血液生化检测、脏器系数和病理学检查,系统地评估了该化合物对小鼠的亚急性毒性作用。结果显示,试验期间无小鼠死亡,在开始用药1周内,高剂量组小鼠有轻微临床毒性症状,2周后症状消失。试验过程中各组小鼠增重差异无统计学意义(P>0.05),长期高剂量给药后小鼠心和肝的脏器系数明显改变(P<0.05),血液红细胞、碱性磷酸酶、肌酐明显增高和葡萄糖、胆固醇、尿酸显著降低(P<0.05),高剂量组肝、肾小部分发生轻微水样变性、点状坏死等病理改变,停药15d后,碱性磷酸酶和尿酸水平与对照组差异有统计学意义(P<0.05)。提示纳川珠利长期大剂量使用可能存在肝、肾等轻微损伤的风险,但损伤是可逆的,停药后短期可逐渐恢复,临床使用相对安全。  相似文献
