Spectrographic determination of barium in biological material

Spectrochemical determination of barium (Ba 2335.₃ Å) in some fatal cases of barium poisoning, and recovery experiments, are reported with and without the use of beryllium (Be 2348.₆ Å) as internal standard (precision ±20%).     

Influence of electricity on post-mortal body temperature

In a case of suicidal application of electricity differences between the rectal temperature of the body and the suspected time of death were observed. In order to answer the question whether an electric current from hand to hand over >30 min led to a rise in body temperature FEM-based computer simulations and animal experiments were carried out. Both resulted in a warming of the soft parts in the arm without warming the body core. Thus a temperature-based estimation of the time since death can also be used in cases with electricity as the cause of death. Besides, in the animal experiment we found a spontaneous rise in the body core temperature even without application of electricity which may be a reason for the typical temperature plateau after death.     

The role of forensic geoscience in wildlife crime detection

The increase in both automation and precision in the analysis of geological materials has had significant impact upon forensic investigations in the last 10 years. There is however, a fundamental philosophical difference between forensic and geological enquiry. This paper presents the results of forensic geoscientific investigations of three cases of wildlife crime. Two cases involve the analysis of soils recovered after incidents of illegal badger baiting in the United Kingdom. The third case involves the illegal importation of Eleonora's Falcon (Falco eleonorae) into the United Kingdom from the Mediterranean. All three cases utilise the analysis of soils by a variety of physical, chemical and biological techniques. These involve mineral and grain size analyses, cation and anion compositions, pH, organic content and pollen analysis. The independent analysis undertaken by specialists in each of these three main fields conclude firstly, that there is a significant similarity between sediments taken at the crime site at both badger setts and with sediments recovered from various spades, shovels and clothing belonging to suspects and secondly, that the soils analysed associated with the removal of the falcon eggs in the Mediterranean contained characteristics similar in many respects to the soils of the breeding areas of F. eleonorae on the cliffs of Mallorca. The use of these independent techniques in wildlife crime detection has great potential given the ubiquitous nature of soils and sediments found in association with wildlife sites.     

ELISA-based determination of opiates in purulent transformation of cadaveric material

Abuse of drugs has been a topical issue up to the present-day. Opiates like morphine and heroin are still prevalent. The routine methods of determination of drugs in blood made within the forensic medical expertise are time-consuming and samples must be specially prepared for them. ELISA, when used for the determination of opiates in blood and urine, significantly cuts the test time. According to our research results, the diagnosis of opiates by ELISA is advisable at the preliminary stage of the forensic expertise of cadaver; the method is informative, which is of extra importance in cases of purulent transformation of cadaveric material.     

Questioning the ‘immortal state’: the Gezi protests and the short-lived human security moment in Turkey

This article has three interrelated objectives: firstly, it challenges monolithic depictions of the 2013 Gezi protests and conceptualizes the so-called ‘Spirit of Gezi’ as a highly influential—albeit temporary—power in the politics of Turkey. Secondly, it traces the success of the HDP (Peoples’ Democratic Party) in the 7 June 2015 parliamentary election back to Gezi while acknowledging the roots of the party within the Kurdish political movement. Thirdly, it examines the manifestation and subsequent decline of what is termed the human security moment in Turkey. The arguments of the work are mostly based on interviews with Gezi activists. It is argued that Gezi produced a discursive challenge to the national security-oriented understanding of the ‘Kurdish question’. Yet, even though the human security-oriented Gezi discourse had brought the Kurdish political movement and the Turkish left together, it ultimately failed to permanently transform Turkish politics due to the collapse of the peace process in June 2015. In addition to contributing to the literature on Gezi, the article also draws insights for security studies. It concludes that alternative discourses to the state-centric securitization approach to conflicts such as the Kurdish question can only have a lasting effect under conditions of ceasefire.
