Most chemical and physical methods employed in visualizing latent marks have shown detrimental effects on human health and, therefore, some research groups have directed their attention to the utilization of various (bio)polymers with the aforementioned purpose. Although chitosan is widely used in medicine, pharmacy, food, and drug delivery systems, there are very few studies that address this biopolymer utilization in forensic applications, such as the detection of latent fingerprints. We used chitosan crosslinked with sodium tripolyphosphate and conjugated with L‐lysine to enhance the visualization of latent fingerprints, due to its ability to interact with fingerprint sweat residues. These conjugates were prepared using different (w/w) amounts of chitosan and tripolyphosphate (6/1; 4/1; 1/1; 1/4; and 1/6), and those with the most promising results (i.e., 6/1 formulation) were investigated in detail. Fourier transform infrared (FT‐IR) spectroscopy confirmed interactions between components of the systems. Optical microscopy and scanning electron microscope (SEM) analysis showed that prepared powder formulations were uniform in size and confirmed that chitosan/tripolyphosphate/lysine conjugates bind easily to the sweat and lipid residues present in the latent fingerprints. The testing of prepared conjugates demonstrated the potential of these systems as bio‐based powder substitution for commercially available powders. 相似文献

By discussing the role of the Balkan Entente within Turkish–Yugoslav relations, this article endeavours to reflect the extent to which the Entente guaranteed security to Turkey and Yugoslavia. It deals with the 1934–41 period, which starts with the formation of the Balkan Entente and ends with the German invasion of Yugoslavia. The article is written mainly based on Yugoslav archival documents and aims to provide an alternative narrative that contests the conventional Turkish view. It also demonstrates that although the political leaders in Turkey and Yugoslavia became more optimistic about the future of the region after having signed the Balkan Entente, their perception of threat changed over time during the period of increasing instability in Europe. 相似文献

This article analyses the impact of the euro crisis on national parliaments and examines their response to the deepening of EU fiscal integration and the correspondent limitation of their budgetary autonomy. It argues that the sovereign debt crisis has provoked the emergence of new channels of parliamentary involvement in EU economic governance. National parliaments have acquired various rights of approval in the European Semester, strengthened the accountability of national governments, reinforced their scrutiny over budgeting, improved their access to information, and created domestic and supranational avenues for deliberation and political contestation of European integration. In these respects, they have undergone further Europeanisation. While these reforms do not outweigh the centralisation of EU powers, they represent an embryonic step in the parliamentary adaptation to the nascent EU fiscal regime. Yet they are unlikely substantially to influence EMU policy‐making processes, because of the democratic disconnect inherent in the EU's multilevel constitution. 相似文献

Aimed at reinforcing the democratic values of freedom of speech and increased diversity in civic access to the means of communication, this paper examines the concept of democracy within an information and communication technology-mediated context. Discussion proceeds with an analysis of orthodox views adopted by Jefferson and the architects of the American Constitution. Building on the Jeffersonian tradition, a critique is presented of present-day, non-transparent constraints on the democratic values of freedom of speech, information access and the structural constrains mitigating unfettered public access to critical information and debate on fundamental social and political issues of the day. The proposed ‘custodiary’ model for the new Democratic Project is premised on the development of a constitutional framework which encourages information diversity and freedom of access and expression as a way of bringing back ‘discourse’ into democratic praxis. 相似文献

This article revisits the balancing act between independence and accountability at the European Central Bank (ECB). It contrasts procedural and substantive concepts of accountability, and challenges the mainstream idea that independence and accountability can be reconciled through narrow mandates, the indiscriminate increase of transparency, the creation of multiple channels of accountability, and the active use of judicial review. These assumptions form the pillars of a procedural type of accountability that promises to resolve the independence/accountability dilemma but fails to do so in practice. The article brings evidence to show how ECB accountability has become a complex administrative exercise that focuses on the procedural steps leading up to monetary and supervisory decisions while simultaneously limiting substantive accountability. The failure to acknowledge the trade‐off between independence and accountability (said to be ‘two sides of the same coin’) has resulted in a tendency to privilege the former over the latter. 相似文献

Multiple giant aneurysms involving the coronary arteries are uncommon and rarely reported. In the presented case, a 63‐year‐old man with poorly controlled hypertension died suddenly. Gross autopsy examination showed multiple giant thrombus‐filled coronary artery aneurysms, atherosclerotic coronary artery disease, and cardiomegaly. Histological sections of the coronary aneurysms showed atherosclerotic changes with both organized and fresh thrombus. Giant coronary aneurysm is defined as a segmental enlargement of a coronary artery with a diameter exceeding 20 mm or more. The main etiology of this nebulous entity is attributed to atherosclerosis and inflammatory or inherited connective tissue disorders with the remainder being congenital, infectious, or idiopathic. Before its cataclysmic presentation, when ruptured or thrombosed, giant coronary aneurysm usually has a silent clinical course. Sudden death owing to giant multiple coronary aneurysms is rare and mandates careful classification of the aneurysms and prudent search for autoimmune‐mediated or genetically based factors for subsequent ancillary autopsy studies. 相似文献
