Povzetek: This work aims to evaluate the corrosion and biocompatibility properties of oxide films generated on Ti6Al4V alloys using both traditional and novel methods. Oxide films were generated by anodization and plasma treatment to achieve a blue surface finish. The oxide films were then characterized and compared to a native film formed on the Ti6Al4V. Electrochemical tests, incorporating potentiodynamic tests and electrochemical impedance spectroscopy, were employed to define the electrochemical resistance of oxides in an environment simulating biological exposure. In vitro tests were conducted to study ion release and biocompatible properties over a 6-week period of exposure to a 0.9 wt% NaCl solution, at body temperature. Various spectroscopic techniques, including ToF-SIMS, XRD, and Raman analysis, were used to study the structure and chemistry of the oxide films. The sub-surface layer was analysed by microstructural investigation. The type of oxidation was found to have a key influence on the oxide composition, especially with respect to the depth distribution of the individual alloy elements through the oxide film. The oxidation process determines which of the alloying elements are released into the environment, as a result of the corrosion reactions.

Povzetek: The paper seeks to examine the social image of suicide at the end of the 19th and the beginning of the 20th century, focusing on the case of Trieste as a major Austrian urban centre, where the suicide rates were visibly increasing from at least the 1870s onwards. The perception of the growing presence of suicide in society made it possible to observe the reflec-tions on suicide from the last quarter of the 19th century, originating from different parts of Europe (Morselli, Masaryk, Durkheim), and at the same time how the discourses around suicide shed light on a somewhat broader picture of society, including its fears (of social problems and change, not least the potential threat of the imitative effect that the daily press was believed to create by reporting on suicides).The newspaper discourse usually followed the scientific publications of the time, and the contemporaneous observations on the mass of suicides were confirmed through statistical analyses and medical, sociological, philosophical, and other debates, while raising many other social issues with which suicide in urban areas could be linked (alcoholism, the growth of the proletariat, poverty, changing values, etc.). All these factors shaped the public debate on suicide as a problem of modern society, with an emphasis on (big) cities, where the prob-lem of suicide was much more pronounced than in smaller, non-industrial towns, or in the countryside of the Austrian Littoral.

Povzetek: The scientific monograph THINKING TOGETHERNESS. PHENOMENOLOGY AND SOCIALITY, edited by Dr. Andrej Božič, comprises the contributions of 32 scholars from the field of phenomenological philosophy. The international and intergenerational configuration of the whole, within which the chapters are meaningfully arranged into seven thematic sections, imparts upon the volume the character of a panoramic scrutiny of the phenomenological manner of confronting the question what co-constitutes the fundamental traits of inter-personal co-habitation with others. The volume offers not only a historical account with regard to the development of phenomenology, but also quite straightforwardly concerns its relevance within the philosophical research that deals with the contemporary problems of society.

Povzetek: Adriano Fabris nas v knjigo uvede s kritiko današnjih predstav o prehranjevanju in odnosu do jedi. Etika uživanja hrane ni povezana niti s temi, ki prepotujejo kilometre, da pridejo do lokala s slow food, niti s temi, ki so zadovoljni z goltanjem sendvičev iz restavracij s fast food. Prav tako ne zadeva obnašanja teh, ki prepovedujejo določeno hrano ali fetišizirajo določene vire hrane, kot so borci za pravice živali, vegetarijanci in vegani. Zadeva tiste, ki se zavedajo, da jesti pomeni odnos do vsega, kar nas lahko nahrani: spoštljiv, uravnotežen odnos, ki upošteva mnogotere vezi, v katere je vpleteno vsako živo bitje. To je delovanje tistih, ki razumejo, da je treba regulirati svojo željo in ne potrebe po prehranjevanju. V drugem poglavju avtor obravnava različne načine reguliranja prehranjevanja s predpisovanjem tega, kaj na bo dovoljeno jesti in kaj ne. V ozadju teh predpisov, zapovedi in prepovedi se kot specifični znak naše omejenosti pojavlja nezmožnost, da bi asimilirali vse, torej povsem zaužili tisto, s čimer se prehranjujemo, s čimer je povezana tudi potreba po puščanju ostankov in odpadkov. V tretjem poglavju je začrtana etiko uživanja hrane, ki izhaja iz predpostavke, da obstoj hrane implicira, spodbuja in izvršuje odnose ter da je prehranjevanje samo odnos. Na to se navezuje vprašanje, ali je za prehranjevanje samega sebe neizogibno izvajati nasilje nad drugimi organizmi. Etični vidik se oblikuje ob predpostavki odgovornega odnosa do živih bitij, ki ne vključuje le nas ljudi, marveč celoten ekosistem. Knjigo zaključuje manjši priročnik (dekalog), ki naj bi z normativnim pristopom usmerjal naše konkretne izbire v pri prehranjevanju. Od naše izbire je odvisno, ali bomo z etično motivirano izbiro dejansko spremenili naš odnos do prehranjevanja. Če bomo to storili, bo to prvi korak k uveljavitvi še bolj splošnih sprememb v našem odnosu do sveta in k odgovorni delitvi skupnega prostora z drugimi živimi bitji.

Povzetek: To gain insight into the current population trends of Carabus variolosus nodulosus in Slovenia and assess the body condition of individuals, data from 17-year monitoring program were analyzed across five geographically distinct regions. The number of beetles captured per trap was recorded, and measurements of live specimens were taken to calculate both national and regional population trends, along with a body condition index. Additionally, linear mixed-effects models were used to examine the potential impact of sex and disturbances on body condition, and to explore the correlation between body condition and population density. The results indicated an overall stable population trend with marked regional differences. No correlation was found between body condition and population density or disturbances, though significant differences in body condition between sexes were observed. This study underscores the importance of long-term and multi-scale monitoring to detect stress factors and potential local extinctions that might otherwise remain undetected and proposes sampling efforts for future monitoring schemes for reliable trend assessments of the species.
