Effects of Re‐heating Tissue Samples to Core Body Temperature on High‐Velocity Ballistic Projectile–tissue Interactions

Damage produced by high‐speed projectiles on organic tissue will depend on the physical properties of the tissues. Conditioning organic tissue samples to human core body temperature (37°C) prior to conducting ballistic experiments enables their behavior to closely mimic that of living tissues. To minimize autolytic changes after death, the tissues are refrigerated soon after their removal from the body and re‐heated to 37°C prior to testing. This research investigates whether heating 50‐mm‐cube samples of porcine liver, kidney, and heart to 37°C for varying durations (maximum 7 h) can affect the penetration response of a high‐speed, steel sphere projectile. Longer conditioning times for heart and liver resulted in a slight loss of velocity/energy of the projectile, but the reverse effect occurred for the kidney. Possible reasons for these trends include autolytic changes causing softening (heart and liver) and dehydration causing an increase in density (kidney).     

Local Nomenklatura in Communist Poland: The Case of the Warsaw Voivodship (1956–1970)

The nomenklatura system granted Poland’s communist party the opportunity to control key recruitment processes. This article analyses the rules whereby party authorities, between 1956 and 1970, introduced and implemented the nomenklatura system locally. The main goal is to examine how the system functioned, focusing on the strategy pursued by local party structures. The article shows that the agents manipulated the system and modified its rules. As a result, the nomenklatura system became one of the key forces behind the growing importance of informal political practices in Poland’s socialist-state system.     

The Catholic Church in Poland on Muslims and Islam

ABSTRACT

The politicization of the increased influx of migrants to Europe in recent years, as well as Islamist terrorist attacks carried out in European cities, have led to a situation in which anti-Muslim sentiments have reached unprecedented levels. It is not only those European countries directly affected by the growth of the Muslim population that register increased generalized negative feelings towards that population, but also those that are home to very small and partially autochthonous Muslim populations, like Poland, which has not served as a transit point or a destination for the increased number of people arriving from Syria and elsewhere to claim asylum in Europe. P?dziwiatr’s article explores the ambiguity of attitudes in the Polish Catholic Church towards Muslims and Islam in these new circumstances. It examines both the Church’s official statements and the opinions of students in Catholic seminaries, which diverge significantly. When the positions of some of these present and future priests are communicated to the public, they contribute to a strengthening of hegemonic representations of Muslims as Others, rather than a deconstruction of them.

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.     

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.
