Bank security dye packs: synthesis, isolation, and characterization of chlorinated products of bleached 1-(methylamino)anthraquinone

Banknote evidence is often submitted after a suspect has attempted to disguise or remove red dye stain that has been released because of an anti-theft device that activates after banknotes have been unlawfully removed from bank premises. Three chlorinated compounds have been synthesized as forensic chemical standards to indicate bank security dye bleaching as a suspect's intentional method for masking a robbery involving dye pack release on banknotes. A novel, facile synthetic method to provide three chlorinated derivatives of 1-(methylamino)anthraquinone (MAAQ) is presented. The synthetic route involved Ultra Clorox bleach as the chlorine source, iron chloride as the catalyst, and MAAQ as the starting material and resulted in a three-component product mixture. Two mono-chlorinated isomers (2-chloro-1-(methylamino)anthraquinone and 4-chloro-1-(methylamino)anthraquinone) and one di-chlorinated compound (2,4-dichloro-1-(methylamino)anthraquinone) of the MAAQ parent molecule were detected by gas chromatography mass spectrometry (GC-MS), and subsequently isolated by liquid chromatography (LC) with postcolumn fraction collection. Although GC-MS is sensitive enough to detect all of the chlorinated products, it is not definitive enough to identify the structural isomers. Liquid-state nuclear magnetic resonance (NMR) spectroscopy was utilized to elucidate structurally the ortho- and para-mono-chlorinated isomers once enough material was properly isolated. A reaction mechanism involving iron is proposed to explain the presence of chlorinated MAAQ species on stolen banknotes after attempted bleaching.

Bacterial Cross‐contamination Potential Associated with Contaminated Currency

Previous studies have shown a significant amount of contaminants on paper currencies. It is important to study the transfer of microorganisms between paper currencies to determine whether it meets the level of a human health threat. This cross‐contamination potential was analyzed by seeding new US 1‐dollar bills with Bacillus thuringiensis, and pressing or rubbing them against clean currency to determine the amount of bacteria transfer to the unseeded currency. The transferred amount of bacteria was recovered, plated, incubated, and the colony‐forming units were quantified. Among the recovery methods tested, the most efficient method, vortexing for 10 min with a recovery efficiency of 40 ± 8.1%, was used in this analysis. The resulting transfer rates were 4.8%, 8.6%, and 14.3% when pressed for 24 h, 72 h, and rubbed together, respectively. These transferred amounts of bacteria are significant and have the potential to spread infectious diseases.     

论伪造货币罪

货币是与国计民生和经济发展关系极为密切,古今中外各国的刑事立法都毫不犹豫地把伪造货币的行为规定为犯罪予以刑法上的严厉打击,以维护货币的独力与稳定。本文就伪造货币罪的概念、构成特征、司法认定和刑事处罚等问题进行了探讨。     

假币犯罪案件的特点与侦查防范

当前,我国假币犯罪活动日渐增多、形势严峻。深入研究假币犯罪的特点、规律以及犯罪原因．是成功遏制假币犯罪的关键。假币犯罪活动,不仅影响我国的市场经济秩序．而且危害国家的经济安全和广大人民群众的根本利益。一些群众因误收假币而受到了严重的经济损失．不仅对银行产生不信任感。由此也引发了不安定的因素,从而影响了社会的经济和治安的稳定。     

侵占罪与挪用型犯罪视角下的货币所有权

货币是刑法分则规定的一些犯罪的犯罪对象,但货币作为一种特殊的种类物,在所有权转移方面有其特殊性,即谁占有货币,谁就取得所有权。据此分析刑法分则规定的与货币的这一特殊性关系密切的一些犯罪,会发现货币不应成为侵占罪的犯罪对象;货币作为挪用型犯罪的犯罪对象时其犯罪客体应是货币的所有权。     

灾后日元升值初探

短期来看,日元汇率没有因经济受到巨大损失而贬值却转向迅速升值在于投资者形成"保险机构或企业资金的资金回流"的预期,投机力量就借助这个题材不断的推升日元。长期来看,这一轮日元升值并不是因贸易摩擦、美国压迫日本的结果,而是与金融危机过程中动荡的国际货币体系有关。日元在国际货币体系内主要执行价值贮藏的功能,而其贸易结算功能相对较弱。日元快速升值的根本原因是日元在估值上存在升值压力,以及日元发挥避险货币和套利交易的作用。中日两国都面临着美元贬值的巨大风险,可采取相互增持对方货币资产的方法,逐渐减少降低外汇储备中美元的比例,建立区域汇率稳定性机制。     

电子货币是货币发展规律作用的必然结果

电子货币作为一种新的派生形式,是货币发展规律作用的必然结果。电子货币不仅具有一般货币的共性,而且具有明显的时代特征。因此,电子货币的出现,并没有否定马克思的货币理论,相反却再次证明了马克思货币理论的科学性。     

Drug Contamination of U.S. Paper Currency and Forensic Relevance of Canine Alert to Paper Currency: A Critical Review of the Scientific Literature

Several studies have reported on wide‐spread contamination of U.S. paper currency with cocaine and to a lesser extent other illicit drugs. Canines are trained and employed to search for and alert to drugs. Canine alert to currency has been used as evidence that currency has been directly involved in illicit drug trafficking to justify currency seizure and forfeiture. This assertion, particularly when the only evidence is based upon canine alert, has been challenged in the courts considering that most currency in circulation is contaminated with cocaine. Comprehensive review of the scientific literature establishes that (i) 67–100% of circulated U.S. currency is contaminated with cocaine ranging from a few nanograms to over one milligram/bill (ii) various biological and environmental parameters impact canine alert to drugs. It is concluded that canine alert to U.S. currency is not sufficiently reliable to determine that currency was directly used in an illicit drug transaction.     

From the ruble zone to the euro zone: the political economy of Estonian macroeconomic policy

This article analyzes Estonian macroeconomic policy since the country regained independence in 1991. Estonia was the first post-communist country to introduce a currency board in 1992, and consecutive governments have systematically prioritized macroeconomic stability and fiscal prudence. Estonia implemented an internal devaluation in 2008–2009, which enabled it to become the first post-Soviet republic to adopt the euro in 2011. This article explores the origins of the currency board and shows how institutions, interests, and ideas have contributed to Estonian exceptionalism in macroeconomic policy and to euro adoption. It demonstrates that the Estonian experience can shed light on the political prerequisites of internal devaluations, which may be of great relevance both to current and future Central and Eastern European euro area members.
