Content available An awkward contaminant: are mercury concentrations in historically collected fossils a result of storage conditions?

EN
High concentrations of mercury (Hg), reaching astonishing values in two cases, have recently been detected in Middle and Late Triassic fossil reptile bones, housed for over 100 years in several Polish museum collections. Since no correlation between either the life modes of these taxa or their burial environment was observed, the studied contaminations seem to be associated with housing conditions. The specimens were kept for an extended amount of time in boxes, in which they were stored soon after finding. A proximity of mercury-containing materials, like mercury fulminate, and unstandardized conditions of storage and conservation of the remains may result in contamination of porous bone with mercury. A detailed knowledge about the housing history of old museum collections has great importance to their prospective studies.

EN
An assemblage of 120 mammal remains of Pleistocene age has been collected from the fluvial deposits of river Raba at a gravel pit in the village of Targowisko, 30 km east of Kraków, southern Poland. Nearly 100 remains represent woolly mammoth Mammuthus primigenius. Other remains belong to four or five such mammal species as horse Equus ferus, woolly rhinoceros Coelodonta antiquitatis, red deer Cervus elaphus and steppe bison Bison priscus or aurochs Bos primigenius. Pleistocene coarse-grained deposits containing isolated bones, teeth and tusks occur in the lowermost part of the fluvial succession in the open pit, presently inundated by groundwater. The surfaces of the majority of bones and teeth show abrasion damages by fluvial transport, including their rounding and smoothing as well as scratches and grooves. Traces of carnivore activity are visible on mammoth and horse bones. The location, dimension and shape of these marks suggest wolf or cave hyena gnawing.

Stable isotope analyses of oxygen are used in anthropology for such purposes as determination of origin of individuals, tracking migration routes or dynamics of human community relocation. The methodology related to oxygen isotope analysis has been founded on the relationship between its isotopic composition within phosphate groups of bone tissue (δ18Op) in individuals being analysed and the water consumed by such individuals (δ18Ow). Such a relationship has been observed in many species of mammals, including humans. However, the influence of culinary practices on the isotopic delta values of apatite phosphates of individuals has not yet been researched. The present study, which was conducted using laboratory rats, is an investigation of the influence of the thermal processing of water drank by such rats on the isotopic composition (δ18Op) of bone apatite. Increasing the value of the isotopic composition of water by about 6.1 ‰ during boiling resulted in an increase in the oxygen isotopic value δ18Op of rats drinking the water by about 4 ‰ (29%). It can be expected that regular consumption of heavily isotopic drinks and foods by humans may cause the δ18Op of individuals to exceed the range of isotopic environmental variability, even by a few per mille.

Praca przedstawia model numeryczny kończyny górnej człowieka przydatny do analizy ryzyka złamania kości kończyny podczas upadku do przodu. W odróżnieniu od innych modeli spotykanych w literaturze, proponowany w tej pracy model uwzględnia wszystkie trzy główne kości kończyny górnej połączone powierzchniami stawowymi w stawie łokciowym i nadgarstkowym przy zastosowaniu kontaktu typu bonded jako jeden złożony układ biomechaniczny. Analizę dynamiczną przeprowadzono dla różnych konfiguracji kości przedramienia, wykorzystując dwa kryteria wytrzymałościowe do oceny potencjalnych miejsc złamań kości kończyny.

The paper presents numerical model of the human upper extremity useful for the analysis of the upper extremity bones fracture risk during the falling process in a forward direction. Unlike previous models met in literature, the proposed in this paper model considers all three main upper extremity bones connected in the elbow and wrist joints by the bonded type contact as one complex biomechanical system. Transient analysis has been carried out for different forearm configurations by using two strength criteria to estimate possible sites of upper extremity bone fractures.

This article is focused on the data concerning properties of carbamazepine, an antiepileptic drug commonly used in everyday medical practice but also frequently misused leading to many reported cases of intoxication. Due to high prevalence of this drug detailed data concerning its pharmacokinetics and prahmacodynamics can be found as well as metabolic paths that have been proven or have not been confirmed yet. For the purpose of toxicological analyses of samples collected postmortem it is also essential to know the possible transformations of an analyte due to microbial metabolism and postmortem changes of the sample matrix. In forensic cases of unavailable or unusable blood samples when advanced stage of decomposition processes in the found body occurs, alternative matrices are required. Presented review describes three types of such matrices: bones, bone marrow and grease in the context of their postmortem changes and suitability as the source of toxicological information.

The paper presents a procedure of modeling of the radial bone humerus bone and ulna bone of human arm. The article describes the problem of the transition from real to digital model. The subject of the research are the human forearm and arm bones, the radius, the ulna and the humerus. It was decided to create a digital model through reverse engineering techniques, using the coordinate arm equipped with set of markers for measuring geometrics, a file containing the point cloud was received, which was later on processed to the solid object by successive operation in CATIA.
