Optimizing Methods for Separation of Adhesive Tape from Fabrics and Obtaining Latent Prints from Adhesive and Non-Adhesive Sides

Fingerprinting is a valued part of forensic science analysis. It has been around for decades, and has advanced with the passing of time. There have been numerous studies of the different ways analysts have encountered fingerprints in the field—but none on those deal with the removal of tape from fabric. To investigate this, eight fabric types (a cotton/polyester mix, spandex, denim, jeans, fleece, flannel, polyester, and vinyl), three commercially available tapes (duct tape, black electrical tape, and packaging tape), have been stuck together and separated with four different techniques (manual pulling apart, Un-Du commercial adhesive remover, liquid nitrogen, and a 1:1 xylene-chloroform mix) and processed with WetWop to determine if usable prints can be obtained. Results have demonstrated that the best separation method for the widest range of fabrics and tapes is liquid nitrogen

Scrap-metal Risk Intervention: Technology Supporting Munitions-Risk Education

With scrap-metal collecting and do-it-yourself demining on the rise in many countries, Allan Vosburgh of the Golden West Humanitarian Foundation has suggested a new type of “MRE”: munitions-risk education. If this idea works, munitions-risk education could not only prevent serious injuries but also may potentially help in the fight against unexploded ordnance

Mine-risk Education and the Amateur Scrap-metal Hunter

In many countries where landmines and unexploded ordnance threaten populations, people ignore warnings about these hazardous explosives to collect explosive remnants of war for the valuable scrap metal they contain. The author discusses a program proposed by the Golden West Humanitarian Foundation to manage this dangerous practice

A Derivation of the Solubility Product Law

Stieglitz1 pointed out in 1908 that the derivation of the solubility product law based on the application of the law of mass action to strong electrolytes is objectionable. Nevertheless many elementary textbooks still give it. Washburn2 later gave a satisfactory thermodynamic derivation, and Butler3 has more recently given a satisfactory statistical one. Another thermodynamic derivation is possible using the now familiar concepts of free energy and activity

Providing IMAS Training to Local Military Forces and Mitigating Long-Term ERW Risks in Vietnam

Residual risk from unexploded ordnance (UXO) is a by-product of all modern conflicts. Developed by the Geneva International Centre for Humanitarian Demining (GICHD), the Management of Residual Explosive Remnants of War (MORE) program seeks to characterize risk and carefully examine the factors involved in reducing long-term risks from munitions.1 MORE looks at many factors, including the impacts of time on munitions, explosives, and fuzing systems. Other critical considerations are the resources available to manage residual UXO and best practices from former conflict areas used to successfully overcome the risk reduction challenges. In Vietnam, the Golden West Humanitarian Foundation (Golden West) conducts a program training the Vietnamese Provincial Military Command (PMC) to conduct explosive ordnance disposal (EOD) to international standards with the goal of building long-term capacity
