The aim of this work is to radiologicaly estimate the width, height and depth of bodies of thoracic and lumbal vertebras. Charts of one hundred and seventeen patients with implanted internal fixateur on the thoracic and lumbal spine, between 01.01.2008. and 31.3.2010. at the Department of Orthopedics and Traumatology - Clinical Centre Sarajevo, were retrieved, and only 14 patients, with totally 46 vetrtebras have meet including criteria (clearly visible measured structures on X-ray and CT scans, and data about implants dimensions). Digitalized anteroposterior and laterolateral X-ray, and transversal and sagital CT scans were basic inputs for measurement of height, width and depth of the vertebral body--CH, CW, CD. The correction of enlargement on X-ray pictures was performed according to known dimensions of implants and the length scale on CT scans. Enlargement of those parameters, from T1 to L5 spine level was from 60 to 100%, except the stagnation in the mid-thoracic region, and decreasing of corporal depth on the L5 vertebra (CD/L5), in comparison to the fourth vertebra (CD/L4). The clinical importance of this work is in estimation and comparison of dimensions of vertebral bodies measured on X-ray and CT scans, as the basic inputs during surgical procedures of vertebroplasty and anterior spondilodesis.

The aim of this study was to evaluate seasonal variation in urea content and other nitrogen compounds (protein, casein, non-protein nitrogen content) of sheep milk as a tool for monitoring the protein nutritional status over the period of two years. The study was performed on three family farms with 150 to 300 sheep per farm using semi-extensive farming management based on pasture, typical for sub-Mediterranean area. Bulk-tank milk samples were taken during the entire milking period (from March to July or August, depending on the year) and were analysed for protein, casein, non-protein nitrogen (NPN) and urea content. Significant effect of the year was observed on urea and NPN content (P<0.05). In addition, seasons had a significant effect on milk protein, urea and casein content (P<0.01). Variations in nitrogen components of sheep milk in Dalmatian hinterland have been significant due to the fact that the semi-extensive farming systems could be strongly affected by climate which directly influence on the quantity and quality of pasture.

This study was focussed on a comprehensive investigation on the state of pollution of the Danube and Sava Rivers in the region of Belgrade. Different complementary analytical approaches were employed covering both i) organic contaminants in the river water by target analyses of hormones and neonicotinoids as well as non-target screening analyses and ii) heavy metals in the sediments. Finally, some common water quality parameters were analysed. The overall state of pollution is on a moderate level. Bulk parameters did not reveal any unusual observations. Moreover, quantification of preselected organic contaminants did not indicate to elevated pollution. More significant contaminations were registered for chromium, nickel, zinc and partially copper in sediments with values above the target values according to Serbian regulations. Lastly, non-target screening analysis revealed a wider spectrum of organic contaminants comprising pharmaceuticals, technical additives, personal care products and pesticides. The study presented a comprehensive view on the state of pollution of the Sava and Danube Rivers and is the base for setting up further monitoring programs. As a superior outcome, it was illustrated how different chemical analyses can result in different assessments of the river quality. A comparison of target and non-target analyses pointed to potential misinterpretation of the real state of pollution.

This study aims to investigate three characteristic representational typologies in Sarajevo, in regard to Henri Lefebvre's theory of “Production of Space.” Representational typologies are considered as a tool in the hands of power holders capable of influencing, motivating or manipulating wider population. The comparative analysis of the deterministic link between the social system and architecture will be examined in order to highlight the universal qualities of architecture capable of outliving the liminal momentum of transitions from one socio-political system to another.

This article aims to revisit an article of my own, published in 1995, about the military dictatorship through music, emphasizing issues such as violence, guerrilla and repressive censorship and the possibility to work with such topics in the classroom. In this article we continue these discussions, seeking to emphasize as the same have been designed in recent years, in particular those related to the teaching of history.
