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

Corruption is perceived in all societies as a social pathology that causes great material and moral damage and is a threat to the society's continual development. Especially in countries with a freshly consolidated democracy, as Slovenia, the phenomena of corruption must be treated with all due attention. This article emphasises that corruption in Slovenia is publicly perceived as one of the most important and even increasing problems in society. We are also analysing one of the crucial side effects of the corruption, resulting itself in ever deeper public distrust to most significant political and administrative institutions. 相似文献

In modern democracies, civil servants have outgrown their classic role as implementors of the orders given by politicians as their masters. They now play an increasingly important role in the exercising of authority – a role which depends to a great degree on politicians themselves. Based on classical politico‐administrative divisions, the main hypothesis of this paper is to claim that, in the case of the post‐communist country of Slovenia, politicians are in charge of policy‐making and possess a dominant role over high‐ranking civil servants, who are mere implementors of policy. To verify this hypothesis, we use several mutually complementary methods and techniques, among them detailed empirical research. We find that the relationship between members of Slovenia's administrative and political elite does show competitive traits, but the conflict between the two groups is not such that would lead to a win‐lose situation. Both high‐ranking civil servants and politicians do in fact have a role as important and irreplaceable actors in the policy‐making process. 相似文献
