Knee joint injuries as a reconstructive factors in car-to-pedestrian accidents.

Knee joint injuries were found in 214 out of 357 fatal pedestrian victims of traffic accidents (60%). The cross-sections of tibial and femoral epiphyses revealed bone bruises (due to compression and avulsion) and the percentage of victims with knee injuries increased to 80% (in the group of lateral impacts - 94%). The bone bruises in the central tibial and femoral condyles were observed only in victims hit in an upright position. There was a strong correlation between the side of impact on the extremities in medium sized pedestrians (from the front, back, lateral and medial side) caused by passenger cars and the mechanism of knee injuries (hyperextension, anterior dislocation of the proximal tibial epiphysis in relation to the femoral condyles, valgus and varus flexion). In the cases of very low impacts (e.g. in very tall victims hit by rapidly breaking wedge-shaped cars) or very high impact (e.g. in very short victims or truck hits) the "reversed" complexes of injuries were found (lever principle). These findings showed that knee joint injuries are useful for determining the car-pedestrian location on collision and the type of vehicle (in hit-and-run accidents).     

Application of Infrared and Raman Spectroscopy in Paint Trace Examination

Raman spectroscopy has proved to be a promising technique in forensic examinations, where optical microscopy, micro‐infrared spectroscopy, and microspectrophotometry in the visible and UV range are used for identification and differentiation between paint traces. Often no organic pigments are detected using Fourier transform infrared spectroscopy, because their content in a trace is usually undetectable. Application of a micro‐Raman spectrometer equipped with several excitation lasers helps forensic experts in paint analysis enabling identification of main pigments. Three cases concerning comparative examination of car paint are discussed in detail. The comparison of Raman spectra of paint chips found on clothing of a victim or smears found on body of a damaged car to these of paint chips originated from the suspected car enabled us to identify the car involved in the accident. When no comparative material is available, the method can be useful in establishing the color and make of the car.     

Some reflections on the duality of regime for software protection in the European Union

Although the framework for protection of computer programs has been established in the European Union more than two decades ago, it has not undergone any major changes. Opinions of Advocate General Yves Bot have convinced the Court to advance the concept of the plurality of copyright regimes applicable to software: source code, object code and documentation would be protected under the Software Directive, whereas interfaces, programming languages, data formats and software manuals are dealt with as literary works under the InfoSoc Directive. In SAS Institute v WPL, the Court also ruled that copyright in a computer program cannot be infringed where the lawful acquirer of the license neither decompiled the object code nor copied the source code of the computer program, but merely studied, observed and tested that program in order to reproduce its functionality in a second program. This ruling paves the way and acknowledges the reverse engineering efforts on the Old Continent.     

Crime in Central and Eastern European Countries in the Enlarged Europe

An enlarged European Union not only means more territory and a greater population, but also more crimes and perpetrators of crimes. The European integration brings a new challenge to criminology. Comparison of crime statistics across countries is still one of the most difficult methodological problems in criminological analyses. Countries differ in respect of their penal systems and penal policies. Reporting and statistical systems are also different. How, then, can one compare crime between European countries? Can one say where it is safer or where the police work better? Can one determine what the manner of data collection should be so that it reflects reality accurately? This article concentrates on a representation of some trends of crime in Central and Eastern European countries. A main source of information about crime are official crime statistics collected according to the methodological rules worked out by the European Sourcebook of Crime and Criminal Justice Statistics. In the case of homicide, police data are confronted with vital statistics gathered by the World Heath Organization (WHO). The statistics on assault and robbery were compared, as much as possible, with the victimization data from the International Crime Victims Survey (ICVS). The socio-economic context of the crime, the main circumstances of the crime statistics, which affected the interpretation of the crime trends for Central and Eastern European Countries, is presented.     

Beliefs on Sexual Violence in the Context of System Justification Theory: The Role of Hostile Sexism and Beliefs in Biological Origins of Gender Differences

Social Justice Research - Estimates suggest that around 20% of women may have experienced rape. Various misconceptions about rape (i.e., rape myths) are closely related to victim blaming. In our...     

Establishing of chemical composition of printing ink

The subject of the examinations was primarily court tax marks of 50 and 200 PLN, which were suspected not to be genuine. Both inks on the questioned marks as well as comparative genuine marks and inks sent by the manufacturer were analyzed. No information about their chemical composition was available from manufacturer. In the examinations, infrared (IR), visible, X-ray fluorescence, and Raman spectrometry were used. The examinations showed that inks and glue on the marks of both values were the same as samples of those sent by the manufacturer. Discrepancies in some results were observed probably due to contamination, that is, an accidental presence of the foreign substance on the surface (e.g., sweat, saliva while sticking the marks to the surface or physical handling of the documents). It was concluded that there are original (genuine) court tax marks.     

Analysis of friction ridge evidence for trace amounts of paracetamol in various pharmaceutical industries by Raman spectroscopy

The detection of potentially harmful substances presents a multifaceted challenge. On one hand, it can directly save lives, on the other, it can significantly aid and enhance police work, thereby increasing the effectiveness of investigations. The research conducted in this study primarily aims to identify paracetamol in fingerprints, considering situations involving direct contact of a person with paracetamol either chronically or in a single dose. The identification procedure presented, utilizing Raman spectroscopy, aims to rapidly detect the xenobiotic following ingestion by an individual, which involves touching the tablet with their fingers—this can be termed as touch evidence in forensic science investigations. Additionally, the authors focus on assessing the impact of additives present in drugs containing paracetamol as the main active ingredient. The screening results obtained will enable us to analyze the composition of drugs in terms of potentially toxic substances, and their influence on the physicochemical activity of the active substance. We successfully identified the paracetamol molecule using a noninvasive forensic trace detection method. Samples in the form of common drugs containing 500 mg of paracetamol were studied. Throughout the study, comprehensive validation of the method was ensured through the utilization of a statistical model, which excluded sensitivity to the presence of other substances, whether additives or from the external environment. The proposed approach to trace the content of substances in fingerprint using Raman scattering analysis provides a useful starting point to enhance current analytical methods not only in forensic science but also in toxicology.     

Carbofuran poisoning of pregnant woman and fetus per ingestion

A case of carbamate pesticide poisoning of a pregnant woman by carbofuran ingestion is presented. The mother recovered from the poisoning in the hospital but necrosis of the fetus was found. Toxicological findings of the liver, brain, and kidney of the fetus revealed carbofuran in concentrations comparable with the mother's blood. Our findings in the case contribute to the research on permeation of the placental barrier by chemical substances.
