We study the impact of grain boundaries (GB) and misorientation angles between grains on electronic transport in 2-dimensional materials. Here we have developed a numerical model based on the first-principles electronic bandstructure calculations in conjunction with a method which computes electron transmission coefficients from simultaneous conservation of energy and momentum at the interface to essentially evaluate GB/interface resistance in a Landauer formalism. We find that the resistance across graphene GBs vary over a wide range depending on misorientation angles and type of GBs, starting from 53 Ω μm for low-mismatch angles in twin (symmetric) GBs to about 1020 Ω μm for 21° mismatch in tilt (asymmetric) GBs. On the other hand, misorientation angles have weak influence on the resistance across MoS2 GBs, ranging from about 130 Ω μm for low mismatch angles to about 6000 Ω μm for 21°. The interface resistance across graphene-MoS2 heterojunctions also exhibits a strong dependence on misorientation angles with resistance values ranging from about 100 Ω μm for low-mismatch angles in Class-I (symmetric) interfaces to 1015 Ω μm for 14° mismatch in Class-II (asymmetric) interfaces. Overall, symmetric homo/heterojunctions exhibit a weak dependence on misorientation angles, while in MoS2 both symmetric and asymmetric GBs show a gradual dependence on mismatch angles.

The achievement of rights of same-sex couples is an actual topic in contemporary law. This is especially in focus of the professional and academic publicity in the transitional countries such as Bosnia and Herzegovina. In this paper authors considered the issue of the achievement of the same-sex couples' rights in the legal system of this country in the context of the European Court of Human Rights practice and obligations arising from the European Convention on Human Rights and its Protocols. The aim of this paper is to determine to which extent the national legal order of Bosnia and Herzegovina, the country trying to accede to European integration, implements european standards of human rights and freedoms with the final goal to point to the omissions and possible directions for reform.

Dementia is a loss of mental ability (ability to think, remember and make logical conclusions) which, in principle affects normal everyday life of a person. Dementia is not a disease but a group of symptoms that may cause different diseases. Symptoms include change of behaviour, character and unexpected changes in the mood. Poor quality of nutrition affects significantly the intensity of dementia. Balanced diet that meets healthy safety standards and requirements will satisfy the needs of an organism for vitamins and minerals and special attention should be given to intake of folic acid, vitamin B12 and minerals zinc and selenium. Intake of omega3 fatty acids is a source of fuel for blood vessels, particularly for the ones of the nervous tissues.

A aventura surrealista e aquela da busca pela liberdade; ela nao deve ser tomada como um fim em si mesma, mas como um ponto de partida para o homem, uma iniciacao que pretende devolver ao homem tudo aquilo que o imperio da razao e o reinado da logica nos fez perder; em outras palavras, o Surrealismo se propoe a reencantar a vida. Para tanto, propoe arrancar o homem de si mesmo e recupera-lo naquilo que nela ha de mais profundo e obscuro e desperta-lo para a experiencia singular do Amor e da Poesia, numa realidade revelada por meio da descoberta do seu ser multiplo e da afirmacao de sua inquietude. Nessa aventura, guiada e dinamizada por tres vetores capitais ─ o amor, a poesia e a liberdade ─, a imaginacao e a grande protagonista que ora se reveste de fantastico e que descobre o maravilhoso.  Destarte, esse artigo visa apresentar como a liberdade, o fantastico, a imaginacao e o maravilhoso estao intrinsicamente ligados e, ao faze-lo, esclarecer a propria nocao surrealista do maravilhoso.

Abstract Educators working in diverse contexts and looking to promote language learning, as well as maintaining home languages, often encounter resistance and negativity directed towards a wide range of languages resulting in language loss at the individual level and language death at a societal level. On the other hand, a small number of languages are regarded as high status languages, in demand to study and speak. This paper has two aims: firstly, to identify processes which result in different attitudes to languages, which will be termed: language hierarchies and, secondly, to suggest an innovative way of creating conditions for development of ‘hierarchy-free education policy and practice’. In order to exemplify these processes the author’s previous research conducted in London and Cardiff is used. Hierarchy-free policy and practice is promoted as a necessary condition for sustainability of endangered languages. The second part of this paper introduces the concept of: ‘Healthy Linguistic Diet’ (Mehmedbegović 2011) and makes a proposal based on this concept for a new, cognitive-based approach to policy and practice in education which would help eradicate language hierarchies. This section presents latest research evidence from cognitive neuroscience, which supports the argument that all stakeholders in education and wider society would benefit from a shift in attitudes and approach to bilingualism and learning other languages. The benefits at the individual and societal level are so significant that acting on this evidence is not only an educational, but also a health and moral imperative too. In the conclusion, I give recommendations in terms of how this new strategy could be developed and implemented.

Cloud computing is a trending technology, as it reduces the cost of running a business. However, many companies are skeptic moving about towards cloud due to the security concerns. Based on the Cloud Security Alliance report, Denial of Service (DoS) attacks are among top 12 attacks in the cloud computing. Therefore, it is important to develop a mechanism for detection and prevention of these attacks. The aim of this paper is to evaluate Support Vector Machine (SVM) algorithm in creating the model for classification of DoS attacks and normal network behaviors. The study was performed in several phases: a) attack simulation, b) data collection, c)feature selection, and d) classification. The proposedmodel achieved 100% classification accuracy with true positive rate (TPR) of 100%. SVM showed outstanding performance in DoS attack detection and proves that it serves as a valuable asset in the network security area.

Abstract Semantic fluency is a measure of verbal functioning and cognitive flexibility. Its development is particularly rapid in preschool years. The goal of this study was to examine semantic fluency in preschool children in relation to child’s age and gender. The sample for this study comprised 133 children aged 3–6 years (mean age = 56.7 months; SD = 11.1 months) from Canton Sarajevo, Bosnia and Herzegovina. In relation to child’s gender, there were 62 girls (46.6%) and 71 boys (53.8%). We used three different semantic fluency categories: animals, food and music instruments. The results of this study confirmed the effect of age on semantic fluency improvement. However, there were slightly different developmental trends for boys and girls in semantic fluency tasks. Girls achieved higher mean scores in all three semantic fluency tasks, but statistically significant differences were only for the category of music instruments. Given the rapid growth in semantic fluency in preschool children, it is very important to actively promote its development in early years.

Background The purpose of this study was to determine how American College of Cardiology/American Heart Association (ACC/AHA) 2013 and European Society of Cardiology 2016 guidelines for the primary prevention of atherosclerotic cardiovascular disease (CVD) compare in reflecting the totality of accrued randomised clinical trial evidence for statin treatment at population level. Methods From 1997–2008, 7279 participants aged 45–75 years, free of atherosclerotic cardiovascular disease, from the population-based Rotterdam Study were included. For each participant, we compared eligibility for each one of 11 randomised clinical trials on statin use in primary prevention of CVD, with recommendations on lipid-lowering therapy from the ACC/AHA and European Society of Cardiology (ESC) guidelines. Atherosclerotic cardiovascular disease incidence and cardiovascular disease mortality rates were calculated. Results The proportion of participants eligible for each trial ranged from 0.4% for ALLHAT-LLT to 30.8% for MEGA. The likelihood of being recommended for lipid-lowering treatment was lowest for those eligible for low-to-intermediate risk RCTs (HOPE-3, MEGA, and JUPITER), and highest for high-risk individuals with diabetes (MRC/BHF HPS, CARDS, and ASPEN) or elderly PROSPER. Eligibility for an increasing number of randomised clinical trials correlated with a greater likelihood of being recommended lipid-lowering treatment by either guideline (p < 0.001 for both guidelines). Conclusion Compared to RCTs done in high risk populations, randomised clinical trials targeting low-to-intermediate risk populations are less well-reflected in the ACC/AHA, and even less so in the ESC guideline recommendations. Importantly, the low-to-intermediate risk population targeted by HOPE-3, the most recent randomised clinical trial in this field, is not well-captured by the current European prevention guidelines and should be specifically considered in future iterations of the guidelines.

Toma-se a obra de Roland Barthes como materia de investigacao. Nela, a nocao de Viver-junto sugere um imaginario de aula enquanto espaco idiorritmico, uma vida em comum na qual desejo e ritmo individuais encontram seus lugares. Atraves de proposicoes sobre preparacao, pratica e registro da aula, lida-se com nocoes barthesianas tais como fantasia, corpo e texto. Nesse percurso, discute-se as posicoes ocupadas por professor, aluno e os modos pelos quais saber e cultura veiculados ao ensino podem construir um espaco propicio a producao de diferencas, a quebra da reproducao de papeis e de discursos. Enquanto pratica de idiorritmia, o ensino efetiva um modo de estar junto no qual o movimento do sentido se constitui como a simples sugestao de um disparo, uma centelha capaz de acender o desejo.
