Ovaj rad usmjeren je na proučavanje prijateljskih odnosa unutar razrednog odjela. Odnosi među vršnjacima izuzetno su važni u školskom razdoblju, a nedostatak ili trajne teškoće u prijateljskim odnosima mogu se reflektirati na uspjeh učenika, usvajanje nastavnih sadržaja, sliku učenika o sebi, socijalni status i socijalni uspjeh itd. Cilj empirijskog dijela rada je ispitati kvalitetu prijateljskih odnosa unutar razrednog odjela u kategoriji ‘najbolji prijatelj’. Iz cilja istraživanja proizašla su tri istraživačka pitanja: Kakav je profil prijateljskih odnosa u kategoriji ‘najbolji prijatelj’? Kako izgleda hijerarhijska struktura dimenzija kvalitete prijateljstva u ponuđenim kategorijama? Koje karakteristike opisuju najboljeg prijatelja i idealnog prijatelja? Rezultati istraživanja utvrđuju dva profila: opći te profil blizine i roditeljske uključenosti. Utvrđivanje hijerarhijske strukture ukazalo je na važnost brige i priznanja (dječaci) te pouzdanosti i rješavanja problema (djevojčice). Vrh hijerarhijske ljestvice zauzimaju dimenzije priznanja i pouzdanosti. Kao najznačajnije karakteristike koje opisuju najboljeg prijatelja ističu se razgovor i zajedničko provođenje vremena, povjeravanje i pomoć, a u idealnom prijateljstvu izdvajaju se moralne vrijednosti prijatelja.

This paper investigates how successful B2 level English language learners (ELLs), high school students are in translating a group of most common false friends (FFs) from English to BCS and vice versa and examines whether they are more successful in translating absolute or partial FFs. In line with the classification by Otwinowska-Kasztelanic (2015), false friends are considered to be a class of cognates. They are further sub-classified into absolute FFs, which have the same or similar form and dissimilar meaning in two languages (e.g. eventually, meaning finally in English and eventualno, meaning possibly in BCS) and partial false friends with the same or similar form and one same and another dissimilar meaning. (e.g. argument in English, meaning reason, the same as argument in BSC and disagreement, the meaning for which a different word is used in BCS, rasprava). Due to their deceptive nature, FFs have been researched within different theoretical frameworks - theoretical, contrastive, applied linguistics, semantics, pragmatics and translation studies. By means of a survey and descriptive and inferential statistics, this paper confirms the hypothesis that there is a statistically significant difference between correct translation of FFs from English to BCS and their correct translation from BCS to English. Furthermore, the second hypothesis was also confirmed, namely that the B2 ELLs are more successful in translating partial than in translating absolute FFs. The research results suggest that in teaching FFs as items of deceptive vocabulary both explicit and implicit methods need to be applied

Deep eutectic solvents (DESs), as an alternative to ionic liquids, have greener credentials than ionic liquids and have attracted increasing attention in many applications. Choline chloride-based DESs in combination with different hydrogen bond donors (organic acid, sugars and urea), showed a high extraction efficiency. The aim of this study was to examine the possible effects of choline chloride-based eutectic solvents on the antioxidant and antimicrobial activity of lemon and mandarin orange seed extracts. Lactic acid, glucose, urea and water were used to prepare choline chloride-based Natural Deep Eutectic Solvents (NADESs). Ferric-Reducing Antioxidant Power (FRAP) Assay and 2,2-diphenyl-1-picryl-hydrazyl (DPPH) method were used to determine Original Research Article Kolarević et al.; IRJPAC, 21(23): 120-128, 2020; Article no.IRJPAC.63470 121 antioxidant activity. Antibacterial activity was investigated by diffusion method on reference bacterial strains E. coli, E. faecalis, S. aureus, B. subtilis and L. monocytogenes. The analysis revealed a significant reduction potential of the eutectic solvent based on lactic acid as well as significant antioxidant activity of lemon and mandarin seed extracts. In general, mandarin extracts showed better antioxidant capacity. In vitro antibacterial activity assays showed a complete absence of bacterial growth inhibition of the extracts. However, eutectic solvents with lactic acid have shown a significant antimicrobial effect.

In adults 65 years or older, falls or other neuromotor dysfunctions are often framed as walking-related declines in motor skill; the frequent occurrence of such decline in walking-related motor skill motivates the need for an improved understanding of the motor skill of walking. Simple gait measurements, such as speed, do not provide adequate information about the quality of the body motion’s translation during walking. Gait measures from accelerometers can enrich measurements of walking and motor performance. This review article will categorize the aspects of the motor skill of walking and review how trunk-acceleration gait measures during walking can be mapped to motor skill aspects, satisfying a clinical need to understand how well accelerometer measures assess gait. We will clarify how to leverage more complicated acceleration measures to make accurate motor skill decline predictions, thus furthering fall research in older adults.

Online crowdsourcing sites/platforms have become popular in recent years. This study aims to uncover when, where, and how language learners in Turkey (TUR), Poland (POL), Macedonia (MAC), and Bosnia and Herzegovina (B&H) make use of the available crowdsourcing websites/games to learn foreign languages. To ensure parallelism among the data collected in the four countries, a cross-culturally appropriate online questionnaire in English comprised of two parts was designed for this study. Part one gathered information about the use of crowdsourcing sites, tools, and games, while part two elicited background information related to the participants (N=211). The data were analysed considering country- and context-specific variables. The results show that there are more similarities than differences in the ways informants in the studied countries perceive, and employ crowdsourcing resources to learn languages. Therefore, the findings might provide insights for experts, material developers and teacher trainers striving to create cross-culturally valid crowdsourcing platforms/games.

The prospect of a transnational feminist coalition is one of the most challenging questions that feminism faces today. The author analyzes Beauvoir’s involvement with the Algerian decolonization movement and her own self-critique as instructive tools for forming better ways for feminists to engage transnationally. Beauvoir’s existentialist ethics, political writings, and activism continue to offer models for developing an anticolonial and anti-imperialist transnational feminist ethics and are an underexplored resource in transnational feminist scholarship.

Carbonation of concrete is generally assumed to lead to reinforcing steel corrosion. This mindset has long dictated the research priorities surrounding the developments towards new, low-emission binders. Here, by reviewing documented practical experience and scientific literature, we show that this widely held view is too simplistic. In fact, there are many cases from engineering practice where carbonation of the cementitious matrix surrounding the steel did not lead to noticeable corrosion or to corrosion-related damage at the level of a structure. The influencing factors that can, however, lead to considerable corrosion damage are identified as the moisture state, the microstructure of the carbonated concrete, various species that may be present – even in minor amounts – in the concrete pore solution, and the cover depth. The circumstance that a reduced pH alone is not sufficient to lead to significant steel corrosion in concrete seriously challenges the established approach of assessing the  durability performance based on carbonation testing and modeling. At the same time, this circumstance offers great opportunities for reducing the environmental impact of concrete structures with low-emission binders. To realize these opportunities, the focus in research and engineering should shift from studying carbonation to studying corrosion of steel in carbonated concrete.
