Abstract – Traffic safety should always be prioritized in all traffic systems. As the railway is a high-level complex technical and technological system, many factors affect its safety. Two factors that are the subject of research in this paper are train stopping distance and overlap. Keywords – Railway Traffic Safety, Train Stopping Distance, Overlap.

The efficient development and utilisation of magnetic nanoparticles (MNPs) for applications in enhanced biosensing relies on the use of magnetisation dynamics, which are primarily governed by the time-dependent motion of the magnetisation due to externally applied magnetic fields. An accurate description of the physics involved is complex and not yet fully understood, especially in the frequency range where Néel and Brownian relaxation processes compete. However, even though it is well known that non-zero, non-static local fields significantly influence these magnetisation dynamics, the modelling of magnetic dynamics for MNPs often uses zero-field dynamics or a static Langevin approach. In this paper, we developed an approximation to model and evaluate its performance for MNPs exposed to a magnetic field with varying amplitude and frequency. This model was initially developed to predict superparamagnetic nanoparticle behaviour in differential magnetometry applications but it can also be applied to similar techniques such as magnetic particle imaging and frequency mixing. Our model was based upon the Fokker–Planck equations for the two relaxation mechanisms. The equations were solved through numerical approximation and they were then combined, while taking into account the particle size distribution and the respective anisotropy distribution. Our model was evaluated for Synomag®-D70, Synomag®-D50 and SHP-15, which resulted in an overall good agreement between measurement and simulation.

The research aimed to determine the start, end and duration of leafing phases, the degree of plant damage caused by late spring frost, and the retention of leaves in autumn. The research was conducted in the international common beech provenance test in Bosnia and Herzegovina. The test contains eight provenances from Bosnia and Herzegovina, four from Germany, three from Serbia, two each from Croatia, Romania and Switzerland, and one from Hungary. Leafing phenology, canopy damage caused by late spring frost, and leaf retention were assessed in 2019. Most provenances started opening buds on 17 April 2019. Complete canopy damage affected the highest percentage of plants in provenance BW Bad Wildbad, Germany (68 %), and the lowest in provenance Konjuh Kladanj, Bosnia and Herzegovina (3.2 %). Provenance Herzogenbuchsee from Switzerland had the highest percentage of winter leaf retention (37.5 % of plants). The results can be used in choosing provenances that are resistant to low temperatures in zones of late spring and early autumn frost.

Globalna pandemija prouzrokovana virusom COVID-19 bitno je utjecala na poslovanje u visokoškolskim bibliotekama u cijelom svijetu, a cilj ovoga istraživanja je utvrditi kako su javne visokoškolske biblioteke u Federaciji Bosne i Hercegovine prilagodile i/ili redefinirale svoje bibliotečko-informacijske usluge pandemijskim okolnostima rada. Za potrebe prikupljanja takvih podataka, anketirani su samo bibliotekari/ke onih javnih visokoškolskih biblioteka koje imaju kontakt (e-mail) na web stranici fakulteta / akademije / univerziteta, a samo istraživanje, koje je kvantitativne prirode, realizirano je korištenjem posebno kreiranog anketnog upitnika, upotrebom Google Forms, u junu 2021. godine. Od ukupno 47 mapiranih biblioteka, 26 biblioteka je sudjelovalo u ispunjavanju ankete (ukupno 55,3%). U ovom istraživačkom radu, koji je prvi ove vrste u Federaciji Bosne i Hercegovine, donose se pristupi visokoškolskih biblioteka koje, za razliku od visokoškolskih biblioteka iz razvijenih evropskih zemalja, djeluju u vrlo specifičnim uslovima koje, prije svega, karakteriziraju ograničeni i nedovoljni budžeti za nabavku građe, ali i nedostatak osnovne IT opreme. Rezultati pokazuju da su uprkos zatečenim, često neodgovarajućim elementarnim uslovima rada, visokoškolski bibliotekari ulagali izvjesne napore orijentirane ka zadovoljenju informacijskih potreba korisnika tokom svjetske zdravstvene krize, ali i da je pandemija naglasila hitnu potrebu digitalne transformacije istraživanjem obuhvaćenih visokoškolskih biblioteka. = The global pandemic caused by the COVID-19 virus has significantly affected library processes and procedures in academic libraries worldwide, and the aim of this study is to determine how public academic libraries in the Federation of Bosnia and Herzegovina (FB&H) have adapted and/or redefined their library and information services to pandemic circumstances. For the purposes of collecting such data, only librarians of those public academic libraries who have contact information (e-mail) displayed on the faculty / academy / university website were surveyed. The research itself, which is of a quantitative nature, was realized by using a survey questionnaire, which was created on Google Forms, in June 2021. Out of a total of 47 mapped libraries, 26 academic libraries participated in the survey (response rate of 55.3%). This research paper, which is first of its kind in Federation of Bosnia and Herzegovina, brings approaches of academic libraries which, unlike academic libraries from developed European countries, operate in very specific circumstances which are primarily characterized by limited and insufficient budgets for procurement of collections but also basic IT equipment. Results showed that despite the found inadequate elementary working conditions, academic librarians made certain efforts aimed towards meeting the information needs of library users during the world health crisis, but also that the pandemic emphasized the urgent need for digital transformation of surveyed academic libraries.

Abstract The importance of the English language in a contemporary globalized world leads to borrowing of English words into many languages, including Bosnian. The current research investigates the knowledge of the original English written form and translation of the English-origin youth-related words (anglicisms) among young native speakers of Bosnian. The study included 345 Bosnian and Herzegovinian high school students, both males and females, in 9 cities. The findings revealed that the usage of Anglicisms among Bosnian youth is not so frequent and that young people in Bosnia and Herzegovina are more familiar with the original written forms than with their translation/synonyms in the Bosnian language. Moreover, knowledge of these two forms of anglicisms shows variation only relative to a grade in English, while gender and age were found to be irrelevant. Also, no difference was shown in the knowledge of anglicisms in different fields: sports, fashion, and science and technology. Further research is recommended to study these and other youth-related anglicisms on a larger population sample.

Surgically perforated stomach (since direct injury in rats until persisting defect and huge adhesions (day 1, day 7)) fairly represent an unresolved cytoprotection issue, and thereby, we focused resolving of the immediate triad, particular vascular failure (vessels 'disappear'/empty), prolonged bleeding, debilitated defect large widening. Agents (mg/kg) or saline (controls) were given at 1 min post-injury as an abdominal bath (10 ml/rat throughout 2 min). Within 1 - 15 min post-injury period, with cytoprotective BPC 157 (0.01 μg), the rapidly restored vessels 'run' (vessels filled/reappeared) toward the perforated defect, and there is less bleeding, and defect contraction; advanced perforated lesion healing (day 1) to complete healing (day 7), and less adhesions. With pantoprazole (10 mg), early (vessels (worsening), bleeding (prolongation), defect (attenuated widening)) effect means eventual lesions and adhesions severity as in controls. Ranitidine (10 mg) early effect (vessels (improvement), bleeding (less bleeding), defect (eliminated widening, defect not changed)) means final lesions attenuation, but not complete healing, less adhesions. L-NAME (5 mg) early (vessels worsening, less bleeding, attenuated defect widening) and final (lesions aggravation, more adhesions) effect, versus L-arginine (100 mg) early (vessels improvement, more bleeding, attenuated defect widening) and final (lesions attenuation, less adhesions) effect, combined few simultaneously occurring nitric oxide (NO)-system distinct processes. Finally, in the stomach tissue surrounding defect, increased malondialdehyde (MDA)- and decreased NO-values, BPC 157 reversed to the normal healthy values, and mRNA expression studies (Cox2, VEGFa, Nos1, Nos 2, Nos3, Nkap (NF-kappa-B-activating protein gene)), done at that very early post-perforation-time, indicate a way how BPC 157 may act beneficially in the perforated stomach lesion throughout NO- and prostaglandinds-system.

Abstract In the process of designing a system, it is necessary to identify potential threats to that system and to include appropriate countermeasures. The process that helps in finding problems in the initial phase of the system design is the threat modeling. Creating a threat model consists of several steps and there are many tools that can help in automating the procedure. This article deals with the threat analysis for an Ambient Assisted Living (AAL) system based on Wireless Sensor Network (WSN), whose main function is to provide information for carers in order to provide the best possible help to the elderly and disabled. We have identified and analysed 99 potential threats to the considered system, where Denial of Service (DoS) resulted in being the most represented class of threats. After conducting the threat assessment, the obtained results showed that the majority of threats are high-risk and justified the use of threat modeling in the design phase, since they can be utilized in further system development stages.

O amendoim é uma cultura agrícola amplamente conhecida no Brasil. O consumo in natura é o principal meio de aproveitamento da produção. Originário da América do Sul é uma das oleaginosas mais cultivadas em todo mundo, em razão da grande variabilidade nas formas de consumo, sabor e adaptabilidade de produção em áreas tropicais e subtropicais. O objetivo do presente trabalho foi avaliar o desempenho das características agronômicas de crescimento e produtividade de cinco acessos de amendoim sob adubação orgânica. O trabalho foi conduzido no câmpus das Auroras da Unilab, entre abril e julho de 2018. Foi utilizado um delineamento estatístico de blocos casualizados (DBC) com cinco tratamentos e seis repetições. Foram analisadas as características agronômicas: Dias de Emergência (DE), Altura das Plântulas (AP), Números de Ramos, Número de Vagens por Planta (NVP), Número de grãos por Planta (NGP), Peso de massa fresca (PMF), Peso de Massa Seca (PMS) e Peso de 100 grãos (P100G). Os dados foram submetidos à análise de variância em delineamentos de blocos casualizados com três repetições. Os quadrados médios foram comparados pelo teste F e as médias pelo teste de Tukey a 5%. Os acessos Unilab 130 e Unilab 138 destacaram-se em peso e produção de vagens sendo bons genótipos de porte rasteiro. Unilab 107 e 124 situaram-se como intermediários aos demais acessos em relação à produção e podem ser considerados para produção desde que atendidas suas exigências de cultivo. Unilab 130 apresenta-se como um bom genótipo a ser utilizado como genitor em programas de melhoramento.
