This study was conducted with aim to determine the relations between motor skills and technical and tactical characteristics of table tennis players. The study was conducted on a sample of 48 of the best seniors with aged 18-36 years old (a representative sample) in Bosnia and Herzegovina. For this purpose was applied the system of (12) variables to estimate the basic motor skills, and (8) variables for evaluation of technical and tactical characteristics of table tennis players. In order to determine the relations between the basic motor skills and technical and tactical characteristics of table tennis players, the method applied was the method of canonical correlation analysis. Establishing the link between these two areas resulted in the separation of one canonical factor which was statistically significant. The most significant information for extracted canonical component gives the coefficients of the structure and the cross-structure. The coefficients of the structure represent the correlations of the original variables with canonical component derived from a set of variables to which this variable originally belongs, while coefficients of cross- structure provide correlations of adequate source variables with canonical component that was created in other set of variables. Onto the isolated canonical function the most significant influence have the variables of hand tapping, throwing a medicine 1kg ball by forehand, boom in gray, long jump from the place, while also slightly smaller significance show other variables, but from the same subspaces of basic motor abilities. Based on the coefficients of the structure can be summarized that all the technical and tactical characteristics highly correlate with the factor isolated from this area which is logical, because all manifest variables represent one area (technical skills / playing skill). The variables that are related to the attack phase (initiative in points) and elements of game movement (the safety and effectiveness of the attack over the table, safety and efficacy of the first entrance, efficiency of game movement) are significantly associated with canonical factor isolated in the area of motor abilities. These variables describe technical structures in which “imposes” and maintains the initiative in the point, and are the most aggressive attack techniques, and generally seek the largest motor engagement. No surprises then that exactly these variables of technical and tactical structures are significantly associated with the factor isolated in the area of motor abilities are the most important.
Introduction: We can define extracranial carotid artery aneurysm (ECAA) as bulb dilatation greater than 200% of the diameter of the internal carotid artery (ICA) or in a case of common carotid artery (CCA) greater than 150% of the diameter. Surgical intervention is required for the treatment of this disease.Case report: This study presents an open vascular surgical procedure to resolve ECAA. We report a case of 61 years old woman with an extracranial internal carotid artery berry aneurysm, presented with a headache and dizziness when turning the head aside. Classic open surgery was performed and the lumen of berry aneurysm was separated with three clips from the lumen of ICA.Conclusions: The open surgical approach is the method of choice for the treatment of extracranial internal carotid artery pathological conditions.
Modern Bosnia and Herzegovina is a multinational and multi-religious country, situated in the western part of the Balkan Peninsula in South-eastern Europe. According to recent archaeological fi ndings, Bosnia and Herzegovina has been occupied by modern humans since the Palaeolithic period. The structure of Bosnia-Herzegovina’s human populations is very complex and specifi c, due to which it is interesting for various population-genetic surveys. The population of Bosnia and Herzegovina has been the focus of bio-anthropological and population genetics studies since the 19th century. The fi rst known bio-anthropological analyses of Bosnia-Herzegovina population were primarily based on the observation of some phenotypic traits. Later examinations included cytogenetic and DNA based molecular markers. The results of all studies which have been done up to date showed no accented genetic difference among the populations (based on geographical regions) with quite high diversity within them. Human population of Bosnia and Herzegovina is closely related to other populations in the Balkans. However, there are still many interesting features hidden within the existing diversity of local human populations that are still waiting to be discovered and described.
Primary and secondary ammonium assimilation is catalyzed by the glutamine synthetase-glutamate synthase (GS-GOGAT) pathway in plants. The Arabidopsis genome contains five cytosolic GS1 genes ( GLN1;1 – GLN1;5 ), one nuclear gene for chloroplastic GS2 isoform ( GLN2 ), two Fd-GOGAT genes ( GLU1 and GLU2 ) and a GLT1 gene coding for NADH-GOGAT. Even though the regulation of GS and GOGAT isoforms has been extensively studied in response to various environmental and metabolic cues in many plant species, little is known about the effects of phytohormones on their regulation. The objective of this study was to investigate the impact of representative plant growth regulators, kinetin (KIN), abscisic acid (ABA), gibberellic acid (GA 3 ) and 2,4-dichlorophenoxyacetic acid (2,4-D), on the expression of A. thaliana GS and GOGAT genes. The obtained results indicate that GS and GOGAT genes are differentially regulated by growth regulators in shoots and roots. KIN and 2,4-D repressed GS and GOGAT expression in roots, with little effect on transcript levels in shoots. KIN affected all tested genes; 2,4-D was apparently more selective and less potent. ABA induced the expression of GLN1;1 and GLU2 in whole seedlings, while GA 3 enhanced the expression of all tested genes in shoots, except GLU2 . The observed expression patterns are discussed in relation to physiological roles of investigated plant growth regulators and N-assimilating enzymes.
In July 2015, Oxford University Press published a substantial volume titled The Oxford Handbook of Applied Ethnomusicology, co-edited by two eminent ethnomusicologists, Svanibor Pettan and Jeff Todd Titon. The book is an impressive collection of different approaches in applied ethnomusicology, developed through a combination of ethnographic research (personal experiences and fieldwork in different parts of the world) and contemporary scholarship.
The paper provides a concise insight into the activity of Slovenian musicians residing in Sarajevo during the Austro-Hungarian administration. Besides the Slovenian musicians’ activities at the collective level, the paper discusses their individual endeavours and also endeavours from perspective of guest artists. Guest Slovenian artists such as Slovenian opera, was one of the most renowned ensemble that visited Austro-Hungarian Bosnia and Herzegovina.
The depth-dependent strain partitioning across the interfaces in the growth direction of the NiAl/Cr(Mo) nanocomposite between the Cr and NiAl lamellae was directly measured experimentally and simulated using a finite element method (FEM). Depth-resolved X-ray microdiffraction demonstrated that in the as-grown state both Cr and NiAl lamellae grow along the direction with the formation of as-grown distinct residual ~0.16% compressive strains for Cr lamellae and ~0.05% tensile strains for NiAl lamellae. Three-dimensional simulations were carried out using an implicit FEM. First simulation was designed to study residual strains in the composite due to cooling resulting in formation of crystals. Strains in the growth direction were computed and compared to those obtained from the microdiffraction experiments. Second simulation was conducted to understand the combined strains resulting from cooling and mechanical indentation of the composite. Numerical results in the growth direction of crystal were compared to experimental results confirming the experimentally observed trends.
O artigo pretende discutir o papel da infância na formacao das educadoras e educadores. Trabalha com a hipotese de que a infância, compreendida como condicao da existencia humana, possa ajudar na construcao de uma formacao que prime pela autonomia das educadoras e educadores. Propoe que nos espacos de formacao se resgatem as narrativas, que se invista na formacao cultural, na experiencia estetica, transformando estes espacos em espacos poeticos. Conclui questionando acerca da possibilidade de se pensar uma formacao que aprenda com a infância; um espaco marcado pela experiencia, onde seja possivel estabelecer relacoes mais infantis consigo, com os outros e com o mundo.
