The 4- Aminophenol (4-AP) colorimetric test is a fast, easy-to-use, and cost-effective presumptive assay of cannabis plant material producing different chromophores with THC-rich cannabis (blue color) and with CBD-rich cannabis (pink color). The main drawback of the 4-AP test is a brief observation window where the color rapidly changes to black, limiting the utility of the test. We now report for the first time, the identification of the product chromophores between 4-AP and CBD/THC as well as propose an explanation and a solution for the color degradation of the chromophores. The identification of the chromophores is provided by spectroscopic (UV–Vis), chromatography, and mass spectrometry (TLC and LC-QToF-MS). Oxidation of excess 4-AP (Reagent A) in the presence of NaOH (Reagent B) produces the black color observed for the previously reported 4-AP tests and reported in the literature. The adjustment of reactants concentrations and volumes of 4-AP:THC/CBD to a 1:1 ratio significantly reduces the black oxidation by-product and increases the observation window up to 2 h instead of the previously reported 5–10 min. For the first time, mass spectrometry and chromatography confirmed that the reaction of THC and CBD with 4-AP produced chromophores with m/z (M + H) = 420, consistent with proposed indophenol structures. The TLC method developed confirmed the separation between CBD and THC chromophores. The specificity of the test is also reported, showing false positive results for the presence of THC (blue color) for samples of thyme and oregano. LDA and SIMCA models showed that the optimized 4-AP procedure performs better than the previously reported 4-AP color test. 相似文献

The social history of coresidence arrangements in the Latvian region suggests that forms of cohabitation without marriage were present in the Latvian population since the eighteenth century when empirical evidence became available. Before the twentieth century, however, these forms remained marginal and seldom involved choice. The subject of severe criticism until the 1960s–1970s, such forms become more widespread thereafter as the Latvian population began to exhibit many key features of a second demographic revolution. Post-Soviet censuses now suggest that such coresidence patterns in the Latvian population approach the levels of those in most western European states, including the Scandinavian countries. 相似文献

This article examines the self-positioning of the three Baltic states in international politics in relation to the major structural pressures challenging the status quo of the transatlantic security configuration. The constitutive role of the Russia-Georgia war of 2008, the global economic recession, the debt crisis in the eurozone, and the shifting policy preferences and force projection of the United States towards Asia are explored as the key sources of the emerging Baltic security predicament. The empirical conclusions of the poststructuralist discourse analysis conducted for this study demonstrate how the Baltic states, in particular Estonia, have recently come to redefine the contents of ‘new’ Europe, thereby shifting the extant fault lines within the European Union. 相似文献

This article links the NATO enlargement debate to the course of civil‐military relations in the Czech Republic and Slovakia. After a general analysis of civil‐military relations and the media, it looks at the NATO membership issues discussed across seven dimensions and their impact on relations between civil society and the military. It concludes that a gap existed between the governing elite and the public in both countries. 相似文献

Herein, we present a case of 53‐year‐old psychotic woman with acute esophageal necrosis (black esophagus), who was found lying on the floor in the living room of her flat. Pillboxes of antipsychotic drugs were located in the bin. External examination of the body was unremarkable. On internal examination, we found acute esophageal necrosis. Histologically, there was complete epithelial necrosis with focal involvement of muscularis mucosae, dense infiltrate of leukocytes, and ulcerations without any viable cells. There was no evidence of underlying organic diseases or trauma. Toxicological analysis revealed a fatal blood level of antipsychotics (haloperidol, zotepine, and chlorprothixene). Death of the deceased was attributed to fatal intoxication with three various types of antipsychotics. As far we know, this is the first described association between so‐called black esophagus and fatal blood level of neuroleptics. 相似文献

All contemporary societies are facing environmental crime as one among many modern threats to the environment and human / animal life and this is due to the unlimited exploitation of natural resources and pollution. The aim of the present paper is to describe different responses to environmental crime and the development of green criminology in South Eastern Europe. In this region environmental crime occurs under the influence of social conditions and circumstances in which the environment is used as a source of resources for survival, as well as economic factors which mean the environment is used as a resource for profit. For countries in South Eastern Europe it is typical that environmental criminals change their modus operandi and adapt to new socio-economic circumstances, use different loopholes in legislation and exploit gaps in infrastructure and enforcement leading to committing environmental offences without being processed and punished. In many countries of South Eastern Europe green criminology is still in its nascent stages but is focusing on similar obstacles and challenges to those identified elsewhere, such as multi-disciplinarity, cooperation with the natural sciences, and responding to particularities in the region, such as pollution of marine and coastal ecosystems, hunting tourism, and organized crimes such as timber logging. 相似文献

The New Jersey Supreme Court's recent decision in Farmers Mutual Fire Insurance Company of Salem v. New Jersey Property-Liability Insurance Guaranty Association holding that a 2004 statutory amendment requires all solvent triggered liability policies be exhausted before the Guaranty Association pays statutory benefits for an insolvent's share has created many uncertainties in allocating long-tail liabilities. This article discusses the implications and the significant limitations of the Farmers Mutual decision and the questions it leaves unanswered, and responds to arguments that the decision supports revisiting other situations where New Jersey's Owens-Illinois methodology allocates losses to the insured. 相似文献
