Heavy metal ATPases (HMAs) are the most important proteins involved in heavy metal accumulation process. Brassica oleracea has 5 HMA (1-5) homologues whose 3D structure has been predicted and validated in this study by different bioinformatics tools. Phylogenetic and multiple sequence alignment analyses showed high relationship between HMA2 and HMA4, while two same domains were identified in all five HMA proteins: E1-E2 ATPase and haloacid dehydrogenase (HAD) domain. Four HMA (2-5) proteins were identified to be localized in the plasma membrane, while HMA1 localization is predicted to be in plastid. Interactome analysis revealed high interaction of all HMA (1-5) proteins with many metal ion binding proteins and chaperones. Among these, interesting and strong interaction is observed between all HMA (1-5) proteins and ATX1, while HMA1, HMA2 and HMA4 have been found to strongly interact with FP3 (farnesylated protein 3) and FP6 (farnesylated protein 6) proteins. Docking site predictions and electrostatic potentials between HMA2/HMA4 and the interactome proteins were explained and discussed in this study.

In this work we describe the development of the kinetic molecular theory of liquids (KMTL) concept inventory, as well as its use in investigating students’ conceptual understanding of the KMTL within the contexts of aggregate states, evaporation, boiling, condensation, conduction, convection, diffusion, and surface tension. We implemented think-alouds to prepare distractors for the closed-ended version of the KMTL, which was administered to two groups of respondents: non-physicists and physicists (166 students in total from the Universities of Rijeka and Split, Croatia). From the think-alouds and results of written survey research we drew conclusions about the students’ understanding of the structure of matter, thermal internal energy, entropy, temperature, and pressure. Our study not only reiterates earlier findings on students’ ideas about the KMTL, it also reveals numerous additional misconceptions that had not been reported earlier. Psychometric analyses support a formative use of the KMTL inventory. The inventory questions may be extensively used for identifying misconceptions, as well as for stimulating classroom discussions and conceptual change.

A acao repetitiva e o esforco fisico podem provocam acidentes como os cortes, quedas, torcoes, causarem problemas nas colunas e pes, alem de caibras e tendinites. Diante deste cenario, o presente estudo  objetivou analisar os riscos  que ocasionam  acidentes de trabalho numa area de usina de acucar e alcool na Zona da Mata Norte do Estado de Pernambuco.  Foram analisados atraves de pesquisa de campo de carater quantitativa, por amostragem com aplicacao de um questionario, com aspectos investigativos, os tipos de acidentes com maiores frequencias, gravidades e quantos dias que este acidente afastou o trabalhador de sua atividade laboral, para assim, compreender e prevenir esses riscos que se acentuam nos canaviais,. Os trabalhadores recebem os EPI’s, mas nao os usam corretamente, utilizando pedra de esmeril para amolar o facao de forma insegura, causando ferimento na mao, dependendo da gravidade o trabalhador pode ficar em media de 7 a 10 dias afastado. E organizada uma forca tarefa no campo com a participacao dos Gerentes do campo, Tecnicos agricolas liderem de turma e em especial os tecnicos do Servico Especializado em Seguranca do Trabalho Rural – SESTR com a realizacaode treinamentos no canavial, educando e conscientizando cada trabalhador sobre a importância de se proteger. O campo recebe esta visita duas vezes por semana, incluindo a presenca da Enfermeira do Trabalho desta forma o indice de acidente por amolar o facao reduziu em media de 70%.  Case study on risks and accidents among rural workers of a plant marta Pernambuco north Abstract : The repetitive action and physical exertion can cause accidents such as cuts, falls, sprains, causing problems in columns and feet, as well as cramps and tendonitis. In this scenario, this study aimed to analyze the risks that cause workplace accidents in an area of sugar and alcohol plant in the Zona da Mata Norte of Pernambuco. Were analyzed by quantitative character of field research, sample by applying a questionnaire with investigative aspects, types of accidents with higher frequencies, severities and how many days this accident away the worker of his labor activity, thus, understand and prevent these risks are accentuated in the cane fields. Workers receive the PPE, but not use them properly, using emery stone to sharpen the knife in an unsafe manner, causing injury to the hand, depending on the severity worker can get an average of 7 to 10 days away. It organized a task force in the field with the participation of field managers, shift to lead agricultural technicians and especially the staff of the Specialized Service in Rural Work Safety - SESTR with realizacaode training in the cane fields, educating and educating each employee of the importance to protect. The field gets this visit twice a week, including the presence of the Labor Nurse this way the accident rate by sharpening the machete reduced by an average of 70%.

Extracurricular activities represent educational, preplanned actions which enable complete confirmation of students’ personality as well as development of their communication skills and competencies; whilst they enable the teachers to expand their educational influence. Modern school can’t be imagined without innovations or modifications to the entire communicational discourse, since its perspective is to be a progressive model whereat main communicational types of behavior are learnt and formed. The research was carried out at primary and secondary schools in the area of Bosnia and Herzegovina (Mostar region) and it included 590 students and 315 teachers. With this empirical research we have tested the presence of a democratic, voluntary, partnership and pedagogic-stimulating communication within the process of putting the extracurricular activities into realization. The goal of our research was to determine whether there is a statistically significant difference between evaluations made by students and those made by teachers of primary and secondary schools that a democratic, voluntary, partnership and pedagogic stimulating communication is mostly dominant in the process of putting extracurricular activities into realization. The results we have collected have shown the difference between students’ and teachers’ perception of dominant communication in realization of extracurricular activities.

Entrepreneurship has an increasingly important role in economic growth and development in both developed and underdeveloped countries. Also, various forms of entrepreneurial behavior are important in promoting economic and social development. Thus, it is not surprising that entrepreneurship and entrepreneurial activity have received a significant attention from both academics and policy makers. It is important for both groups to better understand the various factors that affect and stimulate entrepreneurial behavior. Previous research has shown that entrepreneurial intentions of individuals represent effective and strong explanatory factor that predicts quite well their future entrepreneurial behavior. Also, entrepreneurial intentions are crucial to the entrepreneurial process as an important first step in a series of actions that leads to the creation of entrepreneurial project. Although there are different theoretical models of entrepreneurial intentions in the extant literature, they actually contain conceptually related elements and offer quite comparable interpretations of entrepreneurial intentions. In order to explore entrepreneurial intentions and their antecedents in South-East European context we have conducted a paper-and-pencil self-administered survey among students of economics and business in four South-East European countries, namely: Bosnia and Herzegovina, Croatia, Macedonia and Serbia. The sample consisted of 1200 respondents, 300 of respondents from each country included in study. The highly structured questionnaire with set of items derived from the literature and Likert-type scale were used as data collection instrument. The following scales were included in the questionnaire: locus of control, risk taking propensity, perceived barriers, perceived support factors, personal attitude towards entrepreneurship, perceived behavioral control, subjective norm and entrepreneurial intention (Lumpkin, 1985; Luthje, Franke, 2003; Linan, Chen, 2009). Collected data were analyzed with multiple regression technique in order to explore the effects of various antecedents on entrepreneurial intention in the context of South-East European countries. The results indicate that personal attitude towards entrepreneurship, perceived behavioral control and subjective norm positively and significantly affect entrepreneurial intent. Respondents from Bosnia and Herzegovina exhibit higher levels of entrepreneurial intent compared to other observed countries. The findings of our research provide better understanding of entrepreneurial intentions and their antecedents in the specific post-transition context of South-East European countries. Theoretical and policy implications of research findings are discussed in the paper.

This study reports the analysis of nine bisphenols (BPA, BPAF, BPAP, BPB, BPC, BPE, BPF, BPS, and BPZ) and related compounds (4-cumylphenol and dihydroxybenzophenone) in honey and food simulant. After sample preconcentration with Oasis HLB cartridges, analytes were silylated and analyzed by GC-MS. The validated methods with LODs in sub ng g-1 were applied to 36 honey samples from European and non-European countries and food simulant stored in selected corresponding containers. Honey samples contained BPA, BPAF, BPE, BPF, BPS, and BPZ in amounts up to 107, 53.5, 12.8, 31.6, 302, and 28.4 ng g-1, respectively. Under simulating conditions, BPA and BPAF were detected in food simulant up to 42.2 and 19.8 ng mL-1, respectively. In certain cases, the detected bisphenols in honey probably derive from a source other than the final packaging.

Modrac hydroaccumulation is the largest and most important multi-purpose water resource for water supply to large industrial capacities of importance for Bosnia and Herzegovina, but also for public water supply of Tuzla and Lukavac. Since the water quality of the hydroaccumulation is threatened by the waste water of a large number of different pollutants in the basin area of 1.189 km², and that the useful volume of hydroaccumulation is limited, then during the time it comes to the filling of the hydroaccumulation dominated by coal dust from coal mines in the basin reservoirs. It must be ensured that good quality water is supplied to consumers, especially households and industries, while ensuring hydrobiological minimum dilution of waste water discharged into the river Spreca downstream from dam and reservoir Lukavac.

The traditional architecture of Bosnia and Herzegovina echoes historical and cultural narratives of ancient Ottoman patriarchal society. The Oriental culture had specifically defined the way in which the gender roles in family and society were manifested in the domestic space, and vice versa, space itself was shaped according to the criterion of gender. While exploring the gender criterion of differentiation of space in the traditional Bosnian residential architecture, this paper will particularly focus on the link between female identity and the spatial characteristics of the traditional Bosnian house. Critical evaluation of elements and principles that compose the traditional model of residential space within its cultural and historical context will be followed by a contemporary insight and interpretation of its universal architectural meanings.
