Comparison of presumptive blood test kits including hexagon OBTI

Four presumptive blood tests, Hexagon OBTI, Hemastix(R), Leucomalachite green (LMG), and Kastle-Meyer (KM) were compared for their sensitivity in the identification of dried bloodstains. Stains of varying blood dilutions were subjected to each presumptive test and the results compared. The Hexagon OBTI buffer volume was also reduced to ascertain whether this increased the sensitivity of the kit. The study found that Hemastix(R) was the most sensitive test for trace blood detection. Only with the reduced buffer volume was the Hexagon OBTI kit as sensitive as the LMG and KM tests. However, the Hexagon OBTI kit has the advantage of being a primate specific blood detection kit. This study also investigated whether the OBTI buffer within the kit could be utilized for DNA profiling after presumptive testing. The results show that DNA profiles can be obtained from the Hexagon OBTI kit buffer directly.

A review of quality procedures in the UK forensic sciences: What can the field of digital forensics learn?

With a reliance on the various forms of forensic science evidence in complex criminal investigations, the measures for ensuring its quality are facing increasing scrutiny. Improvements to quality management systems, to ensure both the robust application of scientific principles and the accurate interpretation and reporting of results, have arisen as a consequence of high-profile rebuttals of forensic science evidence, combined with process improvements driven by evaluation of current practice. These improvements are crucial to ensure validity of results as well as providing assurance for all those involved in the Criminal Justice System. This work first examines the quality management systems utilised for the examination and analysis of fingerprint, body fluid and DNA evidence. It then proceeds to highlight an apparent lack of comparable quality assurance mechanisms within the field of digital forensics, one of the newest branches of forensic science. Proposals are provided for the improvement of quality assurance for the digital forensics arena, drawing on the experiences of, and more well-established practices within, other forensic disciplines.     

Was Jerusalem Part of Palestine? The Forgotten City of Ramla, 900–1900

When the Muslims conquered the Levant in the seventh century they at times changed the meaning of ‘Palestine’. They preserved its erstwhile sense as a region but also came to see Palestine as synonymous with the city of Ramla. From the tenth to the early twentieth century, dozens of Muslim exegetes, travellers and chroniclers explained that Ramla and Palestine were the same place. Others thought Palestine was a small region based around Ramla, one that did not include Jerusalem, or that Palestine had much more to do with Ramla than it did Jerusalem. The association had much to do with the cultural tendency in the Arab Middle East to conflate cities and regions as well as the critical role Ramla played in Palestine for much of its history: it served as the capital of the District of Palestine for more than three centuries, its economic hub for many more and its imagined geographical centre up until the early nineteenth century.
