Spatially offset Raman spectroscopy (SORS) for the analysis and detection of packaged pharmaceuticals and concealed drugs

Spatially offset Raman spectroscopy (SORS) is a powerful new technique for the non-invasive detection and identification of concealed substances and drugs. Here, we demonstrate the SORS technique in several scenarios that are relevant to customs screening, postal screening, drug detection and forensics applications. The examples include analysis of a multi-layered postal package to identify a concealed substance; identification of an antibiotic capsule inside its plastic blister pack; analysis of an envelope containing a powder; and identification of a drug dissolved in a clear solvent, contained in a non-transparent plastic bottle. As well as providing practical examples of SORS, the results highlight several considerations regarding the use of SORS in the field, including the advantages of different analysis geometries and the ability to tailor instrument parameters and optics to suit different types of packages and samples. We also discuss the features and benefits of SORS in relation to existing Raman techniques, including confocal microscopy, wide area illumination and the conventional backscattered Raman spectroscopy. The results will contribute to the recognition of SORS as a promising method for the rapid, chemically specific analysis and detection of drugs and pharmaceuticals.     

The persuasive effect of Tsotsitaal in HIV/AIDS material

ABSTRACT

According to Statistics South Africa (2002) HIV infections were the leading cause of death for females between 15 and 39 years of age for the period 1997 to 2001. The South African Department of Health (2003) estimates that 3.1 million women (15–49 years) in South Africa are HIV-infected. The Human Sciences Research Council (HSRC) (2002) claimed that in the 15- to 24-year age group, 12 per cent of the women and 6.1 per cent of the males are HIV-infected. The high incidence of HIV/AIDS has resulted in a number of campaigns that seek to promote safe sex. According to the results that have been published, young people are seen as a high-risk group. However, of the campaigns that seek to address the issue of HIV/AIDS, the loveLife project is the only campaign aimed exclusively at young people. loveLife makes extensive use of the printed media in their campaigns. They claim to speak in a language with which young people will identify. Very little research into the effectiveness of the language use in these campaigns has been undertaken. Saal (2003) examined the effect of teenager slang as used by loveLife among learners in the Western Cape. This research is an extension of the research conducted by Saal (2003), looking in particular at the effect of Tsotsitaal among learners in the Eersterust area. Tsotsitaal is widely used in Eersterust, Gauteng Province, and its persuasive effect in HIV/AIDS material will be examined. Two brochures (written in Standard Afrikaans and Tsotsitaal) were tested in terms of their effect on source–receiver–similarity, source attraction and credibility (source expertise and trustworthiness) as well as persuasiveness. The findings of the study suggested, somewhat surprisingly, that speakers of Standard Afrikaans are rated more favourably than Tsotsitaal speakers in terms of source–receiver–similarity and credibility. The participants also viewed the brochure in Standard Afrikaans as significantly more persuasive than the Tsotsitaal brochure.

A novel FTA™ elute card collection method that improves direct DNA amplification from bloodstained concrete

Concrete is a common construction material found in residential and commercial buildings, bridges and parking lots that is a composite matrix containing aggregate held together with cement. The porous nature of concrete can make the collection and genotyping of biological fluids, such as blood, challenging. Forensic evidence can become embedded within the matrix, potentially reducing the amount of DNA available for analysis. In forensic science, “direct” amplification refers to a genotyping method that amplifies a DNA profile directly from a sample without DNA extraction, saving time and money. We investigated a novel application of Whatman? FTA? Elute cards in their ability to directly amplify PowerPlex® Fusion and Y23 profiles from minute amounts of blood that had been deposited on different concrete structures. In comparison to traditional collection methods, directly profiling blood stained construction materials using FTA? Elute cards increased the percentage loci amplified and significantly improved both allele peak height and peak height ratio while reducing allelic drop-out. FTA? Elute cards can provide a reliable, inexpensive and superior alternative to traditional methods.     

Real‐Time Detection of Concealed Chemical Hazards Under Ambient Light Conditions Using Raman Spectroscopy

Current concerns regarding terrorism and international crime highlight the need for new techniques for detecting unknown and hazardous substances. A novel Raman spectroscopy‐based technique, spatially offset Raman spectroscopy (SORS), was recently devised for noninvasively probing the contents of diffusely scattering and opaque containers. Here, we demonstrate a modified portable SORS sensor for detecting concealed substances in‐field under different background lighting conditions. Samples including explosive precursors, drugs, and an organophosphate insecticide (chemical warfare agent surrogate) were concealed inside diffusely scattering packaging including plastic, paper, and cloth. Measurements were carried out under incandescent and fluorescent light as well as under daylight to assess the suitability of the probe for different real‐life conditions. In each case, it was possible to identify the substances against their reference Raman spectra in less than 1 min. The developed sensor has potential for rapid detection of concealed hazardous substances in airports, mail distribution centers, and customs checkpoints.     

War on Black Men: Arguments for the Legalization of Drugs

Abstract

The leadership of the black community is concerned with welfare, with equality, with unemployment, with discrimination, with racism, with the pay gap, and with dozens of other such traditional issues. Oh, yes, they are also apprehensive about the use of addictive drugs. But, as we speak, young male members of this community are being incarcerated at frightful rates, and, even worse, are killing each other to boot. One would think that this latter issue would occupy the interest of black leaders front and center. After all, there are few worse problems than being jailed or killed. The present paper is dedicated to making the case that the black leadership has its priorities all wrong; that if they were to exercise true leadership, they would see the jailing and murder of young black men as perhaps the greatest threat to their community; and, if so, they would fervently support the legalization of all drugs.
