Experimental Study of Bite Mark Injuries by Digital Analysis

Abstract: This study was based on a morphometric analysis of bite marks starting from the quantitative definition of the anterior teeth by the geometric acquisition of the “injuries,” using bite marks impressed on pig skin and plastic. Each mark was photographed and acquired. A dedicated program automatically supplied the values of the shape factors and the areas of the pattern geometric figures. The values obtained for the homologous samples were compared to the heterologous values. Statistical comparison was made of the sets by linear regression, determining the correlation coefficient and the determination coefficient for each value. Results showed only 4.8% and 2% of overlap between homologous and heterologous values. This study was carried out in attempting to quantitatively define the anterior teeth of the human dentition and the procedure described and the results obtained support the advantage of morphometric studies and computer‐aided programs in this study of bite marks.     

The W***D C*P of 2*1*: FIFA's intellectual property rights in South Africa

Legal context: This article focuses on the relationship between trade markrights and other forms of statutory protection. Key points: FIFA is the proprietor of a number of trade mark registrationsin South Africa. The strength of these registrations is discussedand the view taken that a number are open to attack, in termsof both distinctiveness and user requirements. It is then shownthat, if statutory protection is given for the same words andphrases, the weaknesses of the trade mark registrations willbe avoided. Practical significance: The article serves as an illustration of the manner in whichinternational sporting bodies attempt to extend their IP protectionbeyond the bounds of existing legislation.     

生前与死后电击伤皮肤NSE活性的观察

本实验采用非特异性酯酶Ｎｏｎ－ｓｐｅｃｉｆｉｃＥｓｔｅｒｓｅ（Ｎ．Ｓ．Ｅ）组织化学方法对生前与死后电损伤进行实验研究，发现生前与死后短时间内的电损伤皮肤胶原纤维上ＮＳＥ活性有显著差别（Ｐ＜０．０５），在相同实验条件控制下，电击后存活时间越长，电流斑皮肤周围的酯酶着色反应越深，范围越宽。实验结果表明，Ｎ．Ｓ．Ｅ对于鉴别生前电流斑与死后电流斑具有法医学意义。     

Analytical pyrolysis of Streptococcus saliivarius as and aid to identification in bite-mark investigation

The use of pyrolysis mass spectrometry (Py-MS) and statistical analysis of mass spectra is introduced as a method for “finger-printing” strains of Streptococcus salivarius. The objective is to provide correlative evidence regarding the identity of suspects in cases of assault or rape involving bite-marks. The results of the analysis of isolates from two individuals are presented, illustrating the differentiation of S. salivarius at strain level according to the origin of the isolate.
