Trace analysis of peroxide explosives by high performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry (HPLC-APCI-MS/MS) for forensic applications

An HPLC-APCI-MS(/MS) method for the (trace) analysis of the most commonly encountered peroxide explosives, hexamethylenetriperoxidediamine (HMTD) and triacetonetriperoxide (TATP), has been developed. With this method, HMTD and TATP have been analyzed in the same run. (Pseudo-)molecular ions of these peroxides have been obtained as base peak under the same condition. A series of product ions was produced from these pseudo-molecular ions ([HMTD - 1]+ and [TATP + NH4]+) in the MS/MS analysis. We also pioneered in showing that a TATP molecular ion [TATP + H]+ can be observed with HPLC-MS/MS. The limit of detection for HMTD and TATP was 0.26 and 3.3 ng, respectively, on column by HPLC-MS in the Full Scan mode and 0.08 and 0.8, respectively, by HPLC-APCI-MS/MS in Selected Reaction Monitoring (single mass unit) mode. The method presented has been applied successfully for the identification of peroxides in the bulk solid state (powder sample), as well as in post-blast extracts originating from a forensic case. For the post-blast extracts, the use of tandem MS has been shown clearly to be of crucial importance for the identification and detection of the peroxide explosives.     

Race and problem drug use in an English city

The primary aim of this article is to look at the impact of drugs on the drug-using Black population, and in doing so, the article draws comparative attention to drug use within the White community. The article is based on a research study of problem drug users registered with a London drugs project in 2000 and 2001. During the period of fieldwork, the vast majority of clients of the drug project were male, and the gap in the sex composition of the clients was more conspicuous in the Black group. For the sake of clarity in the use of statistical information, the article draws substance solely from information on the Black and White male clients. The findings present the Black community as a group who is also victimised by drugs but whose experiences of drug victimisation have often been undermined in the "war on drugs" rhetoric about drug trafficking.     

Explaining Regulatory Non-compliance: A Survey Study of Rule Transgression for Two Dutch Instrumental Laws, Applying the Randomized Response Method

Within a rational choice framework, secondary data analysis of a survey study on compliance with two Dutch regulatory laws is carried out. Selection of explanatory variables to be considered is guided by a heuristic device, called the Table-of-Eleven. Using adapted logistic regression analysis, we show that self-reported compliance, measured by means of a randomized response procedure, can be explained in terms of benefits of non-compliance, social norms and deterrence, while knowledge and general norm-conformity have no role to play. The impact of various contributing factors turns out to be rather different in size for the two laws.     

Population data of nine Y-chromosomal STR loci in northern Poland

Allele and haplotype frequencies of nine Y-chromosome STR loci were determined from a sample of 508 unrelated males from north Poland. Three samples containing insertion polymorphism DYS19 (duplication) and DYS385I/II (triplications) were observed.     

What Patent Data Reveal about Universities: The Case of Belgium

In recent years, there has been a surge in patenting by Belgian universities. It appears that this increase can be attributed to growth of biotechnology, where there is a greater propensity to patent, to a desire on the part of universities to enhance commercialization through technology transfer offices (TTOs), and to effective collaboration between universities and government-sponsored research centers. Our qualitative analysis reveals that patent statistics could be a misleading indicator of an individual university's technological productivity, since many inventions are developed at universities, yet applied by other institutions.     

Growing Up Young,Asian and Female in Britain: A Report on Self-harm and Suicide

It is now a well-documented statistic that Asian women between the ages of 15–35 are two to three times more vulnerable to suicide and self-harm than their non-Asian counterparts (Soni-Raleigh, 1996). The article will summarize the findings of the research report Growing Up Young, Asian and Female in Britain (Newham Asian Women's Project, 1998), which aimed to explore the reasons why young Asian women self-harmed and to evaluate the service responses they were given. It also made recommendations aimed at decreasing the high prevalence of suicide and self-harm among young Asian women. The article concludes by reflecting upon the impact and service developments that have been made since the report was published.
