Mixed mountain forests of European beech (Fagus sylvatica L.), Norway spruce (Picea abies (L.) Karst), and silver fir (Abies alba Mill.) cover a total area of more than 10 million hectares in Europe. Due to altitudinal zoning, these forests are particularly vulnerable to climate change. However, as little is known about the long-term development of the productivity and the adaptation and mitigation potential of these forest systems in Europe, reliable information on productivity is required for sustainable forest management. Using generalized additive mixed models this study investigated 60 long-term experimental plots and provides information about the productivity of mixed mountain forests across a variety of European mountain areas in a standardized way for the first time. The average periodic annual volume increment (PAI) of these forests amounts to 9.3 m3ha−1y−1. Despite a significant increase in annual mean temperature the PAI has not changed significantly over the last 30 years. However, at the species level, we found significant changes in the growth dynamics. While beech had a PAI of 8.2 m3ha−1y−1 over the entire period (1980–2010), the PAI of spruce dropped significantly from 14.2 to 10.8 m3ha−1y−1, and the PAI of fir rose significantly from 7.2 to 11.3 m3ha−1y−1. Consequently, we observed stable stand volume increments in relation to climate change.

This article reports on an investigation into the ability of SiO2–Ta2O5 as a new sorbent for simultaneous preconcentration of Cd(ii), Co(ii), Cr(iii), Cu(ii), Fe(iii), Mn(ii), Ni(ii) and Pb(ii) ions from water by the column method and the parameters involved in this process.

Abstract Drug-drug interaction (DDI) is defined as a clinically significant change in the exposure and/or response to a drug caused by co-administration of another drug which may result in a precipitation of an adverse event or alteration of its therapeutic effects. The aim of this systematic review was to provide an overview of DDIs that were actually observed or evaluated in acute coronary syndrome (ACS) patients with particular focus on DDIs with clinical relevance. Electronic searches of the literature were conducted in the following databases: MEDLINE, EBSCO, Scopus, Google Scholar and SCIndeks. A total of 117 articles were included in the review. This review showed that ACS patients can be exposed to a variety of DDIs with diverse outcomes which include decreased efficacy of antiplatelet drugs, thrombolytics or anticoagulants, increased risk of bleeding, rhabdomyolysis, hepatotoxicity, adverse effects on cardiovascular system (e.g. QT interval prolongation, arrhythmias, excessive bradycardia, severe hypotension), serotonin syndrome and drug-induced fever. Majority of the DDIs involved antiplatelet drugs (e.g. aspirin, clopidogrel and ticagrelor). Evidence of some of the reported DDIs is inconclusive as some of the studies have shown conflicting results. There is a need for additional post-marketing and population-based studies to evaluate the true effects of disease states and other factors on the clinical outcomes of DDIs. Clinicians should be attentive to the potential for DDIs and their associated harm in order to minimize or, if possible, avoid medication-related adverse events in ACS patients.

Background: The problem of heavy school bags is a global problem recognized in many countries in Europe and the world, including in Bosnia and Herzegovina. In addition to poor posture habits, "sedentary lifestyles" and insufficient physical activity, school bags is one of the main causes of low back pain and deformity in pupils. The recommendation of the World Health Organization (WHO) is that the weight of the school bag should not exceed 10% of the student's weight. However, in practice these limitations are far from reality with the obvious problems caused by too heavy bags. The aim of the paper is to identify and analyze the backbone load caused by the overweight school backpacks in real school work conditions and eliminate them by creating new solutions that are in line with ergonomic and biomechanical principles, as well as the recommendation given by WHO. Methods: The research included first grade primary school students at the age of seven, including their parents. The research began by interviewing parents with relevant questions, as well as measuring the students’ height and weight and the weight of their school backpacks. The analysis was performed in CATIA v5 software package (Dassault Systemes, Velizy-Villacoublay, France) using its advanced biomechanical modules. By knowing the anthropometric and work environment data with ergonomic design and analysis, the biomechanical analysis, rapid upper limb assessment (RULA) and carry analysis were performed. Results: The conducted survey showed that 84% of students walk from home to school nineteen minutes on average and that 77% of them carry their school backpacks independently. Based on the measurements, it has been shown that, on average, the weight of the school backpacks is well above the WHO recommendation. A study conducted on a representative sample of students confirmed the relation between fatigue and spinal pain caused by carrying a heavy school bag. Computer analysis showed excessive loads on the spinal segment of L4/L5 that were outside the normal range of 3,400 N. Conclusions: A simulated computer analysis using RULA and biomechanical analysis with calculations of maximum loads in the lumbar segment of students found that school backpacks carried by students were too heavy for their age and well beyond the normal limits and WHO recommendations. The analysis showed that it is necessary to reduce the weight of the bag by about 30%.

This article fills a gap in theories of forced migration. We present a new model, motivated by specific features of forced migration during a conflict which do not feature in existing migration models. We incorporate the relative deprivation hypothesis and a new “restoration” hypothesis in order to better explain forced migration as a two-stage process, which starts with conflict and, in some cases, forced displacement in the first stage and continues with emigration in the second stage. A particular feature of our model is that it predicts self-selection of highly skilled individuals into international migration as a result of conflict, since the “restoration” hypothesis assumes that individuals with higher income before conflict are most under pressure to restore their previous income through emigration. The model used in this article to analyse conflict-induced migration could also motivate further modelling to better match the characteristics of migration induced by natural disasters (which are expected to increase in the future as a result of climate change) as well as by large development projects.

Ravnopravnost spolova središnja je tema u čitavome svijetu, pa tako i EU-u, gdje predstavlja jednu od temeljnih vrijednosti koju se nastoji integrirati u sve politike Europske unije, ali i programe financiranja EU-a. Analizirajući istraživanja o ravnopravnosti spolova na institucijama visokoga obrazovanja statistike idu u prilog činjenici da te institucije reproduciraju društvene vrijednosti koje dovode do spolne, rodne pristranosti, odnosno diskriminacije. Statistike pokazuju da postoji vidna razlika u tipičnim karijernim profilima za žene i muškarce, odnosno u odabiru znanstvenih područja. Razvidna je horizontalna segregacija, koja nimalo ne zaostaje za onom drugom, vertikalnom segregacijom koja upućuje na to da je top menadžment, ali i uspješniji karijerni put u visokoobrazovnim institucijama uglavnom rezerviran za muškarce. Ne zanemarujući činjenicu da je dostizanje ravnopravnosti spolova u visokome obrazovanju ipak dugoročni projekt koji bi trebao biti rezultat ne samo sveučilišnih politika, nego i institucionalnih vladinih mjera i politika, ovim se radom konstruktivno promišlja i aktualizira tema za buduća istraživanja, s provedenim istraživanjem na jedanaest ustrojbenih jedinica Sveučilišta u Mostaru.
