Introduction/ Goals: The aim of our study was to point out the importance of the risk factors associated with cervical cancer in an asymptomatic population. Methodology: The study included 860 patients in the period from January 2017 to January 2018, which covered more than 80% of the targeted population in this municipality over the one year study, according to the National Program for Cervical Cancer Prevention in Montenegro. Results: The incidence of PAP III results was statistically significantly higher in women between 40 and 45 years of age compared to other age groups (p< 0.001). PAP III was statistically significant high in subjects who had vaginal delivery (p<0.001), and was statistically significantly more frequent in women with more than two children (p = 0.011), while all the subjects with positive PAP results III had children. PAP III results were statistically significantly higher in subjects who had sexual intercourse before the age of 18 (p< 0.001), and were statistically significantly more frequent in subjects who were on oral contraceptives (p< 0.001). PAP III test results also show a significant difference related to cigarette consumption (p< 0.001). PAP III results were significantly more frequent in subjects with grade III vaginal cleanliness compared to grade II vaginal cleanliness (p<0.001). Conclusion: The number of patients with cervical cancer in Montenegro increased in the period from June 2016 to June 2017, compared to previous years, even though the National Program for Cervical Cancer Prevention that aimed to reduce the number of such patients has been in use in Montenegro since 2011.

Introduction: The small intestine is a challenging organ for clinical and radiological evaluation, and by introducing imaging radiological techniques, not significantly disturbing the comfort and safety of patients, it attempts to obtain adequate diagnosis and valuable information. Aim: The research was conducted with the aim of checking the comparability and potential of diagnostic modality of ultrasound and dynamic contrast enhanced MR Enterography (DCE-MR) in patients with Crohn’s disease. Methods: 55 patients were examined prospectively, and ultrasound examination of the abdomen was performed for all patients before the MR enterography. They were subsequently endoscopically examined or treated surgically, which was taken as a reference. Four parameters characterizing the disease itself were analyzed: bowel wall thickening, presence of abscess, fistula and lymphadenopathy. Results: Comparing the accuracy of the results of ultrasound findings and findings of MR enterography, it was found that there is a significant difference in the results obtained. The study found that the sensitivity for MR enterography for bowel wall thickening was 97.8%, and the specificity was 70%, while the sensitivity for ultrasound for the bowel wall thickening was 51% and the specificity was 100%. In the diagnosis of abscess, there was no significant difference between the results obtained by ultrasound and magnetic resonance imaging (MRI) findings, while in fistula and lymphadenopathy there was a significant difference. Conclusion: Conventional ultrasound is a good orientation method in the initial evaluation of patients with Crohn’s disease, while contrast enhanced MR enterography provides an excellent assessment for disease activity as well as the complications that accompany it.

630*8:620.95(497.6 Kakanj) 620.9:582.632.2(497.6 Kakanj) Biomass has a huge renewable energy source potential, forest biomass in particular. Forest biomass effectively includes aboveground parts of tree trunk including: stem, treetop with leaves/needles, bark, seeds, and cones. Although it is biomass, stump is not used in natural forests. Beech (Fagus sylvatica L.) is a dominant tree in the forests of Bosnia and Herzegovina and it is important raw material used in wood assortment production. Once beech assortment is cut down, processing and hauled there is a significant quantity of unused wood biomass which can be effectively used as source of renewable energy. This is way the objective of this paper was to determine overall quantity of beech tree biomass in Compartment 92, Subcompartment „a”, MU „Žuća-Ribnica“, assess quantity of forest biomass (usable timber left after felling and branches - biomass above 7 cm), determine quantity of forest biomass (wood biomass from 3 to 7 cm), and also quantity of bark. The research included 60 beech trees. Volume of tree trunk and trunk bark was determined by sectioning method and branch mass was determined by weighting. Adjusted values of tree trunk and bark volumes were converted in dry matter mass using information provided by. The research findings showed that 73% (1,605.24 tons) of beech wood biomass is used in Compartment 92, Subcompartment „a”, MU „Žuća-Ribnica“, while 27% (582.59 tons) remain unused in the forest. This altogether indicates that a large portion of beech biomass is not used as energy source.

Introduction: The main route of acquiring infectious blood and body fluids in hospital conditions is accidental exposure to stinging incidents. Aim: The aim of this study was to determine the epidemiological characteristics of accidental exposures to blood-borne pathogens among different professional groups of health care workers (HCWs). Materials and Methods: A cross-sectional study was conducted using the “Questionnaire on the HCWs exposure to blood and blood transmitted infections” at the University Clinical Centre Tuzla, Bosnia and Herzegovina, from the 1st of March to the 31st of December 2014. Study sample consisted of 1031 participants (65% of total employees) stratified into three occupational groups: doctors, nurses and support staff. Results and Discussion: Exposure incident was recorded in 1231 participants (54.8%) at least once in the last 12 months. An average number of exposure incidents per HCWs in total years of service was 7.07± 8.041. Out of total sample, 70% reported at least one type of exposure incident. Nurses had a higher frequency of multiple contacts compared to doctors and support staff (χ2=37.73; df=4; p<0.001). The frequency of reported incidents among nurses at the surgical departments was almost two times higher (1.7). 75.5% (778/1031) of the participants, reported not having been exposed to these incident. Doctors were significantly less likely to report exposure incidents than nurses and support staff. There were significant differences in reporting rate (χ2=32,66; df=4; p<0.001). Conclusion: HCWs in hospitals have a high prevalence of occupational exposure to blood-borne infections. Seventy percent of the HCWs is periodically or constantly exposed to or contact related to blood. Nurses are most frequently exposed occupational group among HCWs, while the lowest reporting rate on an exposure incident is among doctors.

SUMMARY – Lung cancer as the major cause of cancer mortality worldwide includes several histologic subtypes evolving from numerous genetic and epigenetic changes emerging in alveolar, bronchiolar and bronchial epithelium. The majority of cases are diagnosed in advanced stage (i.e. stages IIIB and IV), often with scanty amount of tissue in transbronchial biopsies or cytology specimens. The aim of the present study was to investigate the expression of the scaffolding protein neural precursor cell expressed, developmentally downregulated 9 (NEDD9) in small biopsies of lung adenocarcinoma. The expression of NEDD9 was analyzed immunohistochemically in 71 formalin-fixed and paraffin-embedded transbronchial biopsy specimens of primary lung adenocarcinoma. Nuclear and cytoplasmic NEDD9 expression was detected indicating activation of the epithelial-mesenchymal transition process. Direct relationship between the expression of NEDD9 and survival was not demonstrated.

Abstract Between 1974 and 1975, Zoran Popović, a conceptual artist from Belgrade, Yugoslavia, and his wife Jasna Tijardović, an art historian, spent a year in New York. During that time they engaged closely with the New York Art and Language group. This friendship and collaboration resulted in a rare instance of East-West exchange in Conceptual art: Popović and Tijardović published both co-authored and individual articles in the US journal The Fox, and members of Art and Language (Mel Ramsden, Michael Corris, and Jill Breakstone) gave a seminar in Belgrade's Student Cultural Center in the fall of 1975. One of the most important outcomes of this exchange is Zoran Popović's film Struggle in New York—Борба у Њујорку, which he made on his return visit to New York in the fall of 1976, and which features the members of New York Art and Language and other artists and activists from the downtown Manhattan art scene of the mid-1970s. This essay argues that in this film, Popović uses documentary techniques to establish a space for the display of radical artistic practices that engaged in a vigorous critique of art institutions. In so doing this film marks a limit position of institutional critique that approaches the idea of the abolishment and abandonment of art practice altogether. Further, the essay explores some differences between Conceptual art practice in Yugoslavia and the United States, arguing that Popović uses the crisis that tore the New York Art and Language group apart to address the unraveling of politicized Conceptual art practice in Belgrade's Student Cultural Center.

Abstract The aim of this study was to analyze the values of biochemical parameters in patients with diabetic ketoacidosis and ketonuria. In this prospective comparative study conducted at the Clinical Center of the University of Sarajevo, hundred patients of both genders with diabetes mellitus were enrolled. Newly diagnosed diabetic patients with complications like acute ketoacidosis (n = 50) and ketonuria (n = 50) were included in this study and compared. The values of biochemical parameters in these patients were analyzed. We found that mean values of pH, base excess, hydrogencarbonate, sodium, glucose, urea and creatinine concentrations in patients with ketoacidosis were significantly different compared to patients with ketonuria. The values of potassium and calcium serum concentrations were not significantly different. Also, values of pH, base excess, as well as concentrations of hydrogencarbonate, sodium, potassium, calcium, glucose, urea and creatinine were not significantly different between male and female patients with diabetic ketoacidosis. In patients with diabetic ketonuria we found a correlation between admission glucose concentration and acid-base balance.

Aim: The aim of this paper was to present a 65 year old female patient with chronic heart disease, surgically treated for congenital heart defect type Tetralogy of Fallot. Case report: In the sixth year of life the patient underwent palliative Potts anastomosis surgery which created an anastomosis between the left pulmonary artery and the descending aorta. Total correction was made in 34 years of life, six months after catheterization, which indicated malignant pulmonary hypertension. She is regularly followed up by the cardiologists and receives daily therapy. The present state of the patient is satisfactory with cardiomegaly, light left ventricular dysfunction, moderate mitral and tricuspid regurgitation, pulmonary arterial hypertension, and aneurysmatic dilatation of left pulmonary artery as well as atrial fibrillation. Conclusion: The intense development of cardiology and cardiac surgery in the USA in children and adults over the last fifty years has led to the extension and improvement of the quality of life.

The aim of this research is to determine the elastic (repulsive) properties of the futsal ball depending on the air pressure in it. Futsal ball of standard dimensions was released on the fl at solid surface from the height of nine meters for four times. At the fi rst release the air in the ball was under prescribed pressure. At the second release the pressure in the pumped ball is reduced by 5%, at the third reduced by an additional 5%, at the fourth reduced by another 5%. The setting of the experiment was carried by cinema shooting of free fall of the prescribed futsal ball and a series of rebounds after the rejection of solid surfaces. One can conclude that the distance crossed and the total duration of four successive bouncing mostly dependent on inner pressure. In this study, the initial speed of a futsal ball was unchanged and only inner pressures were changed. It was determined how much the height of the rebound is reduced and the duration of the rebound, respectively, depending on the reduction of inner pressure. Overall, it can be concluded that the initial speed of the ball can be increased by increasing the inner pressure in the ball.

Analysis of electric power system reliability presented in this paper, refers to complex (composite) systems. General issue of assessment of complex electric power system reliability is how to implement and solve mathematical system equivalents and their possible states, taking into account as many possible effects, impacts and conditions of their real functions. Number of possible states of the system in real conditions can be very big, so it is extremely difficult to explore all cases of assessing the reliability of such systems. In this paper, the methods of determining possible states of the system, as well as the methods of determining system deficit, are presented and analysed. For calculations of electric power system reliability, in order to carry out a complete analysis and calculation of characteristic system reliability parameters, it is necessary to determine deficit of electricity. The paper also presents the concrete results obtained using the developed mathematical model and software program developed on its basis.

Mapping an unknown large-scale marine area by a side-scan sonar onboard a marine vehicle as quickly as possible is often of great importance. It is also important that a-priori unknown interesting parts of the area are scanned in more detail, i.e. with the removal of sonic shadows. In contrast to the standard overlap-all-sonar-ranges lawnmower pattern, which is an offline static coverage problem solution for side-scan sonar missions, here a novel online side-scan sonar data-driven coverage solution is proposed. The proposed coverage algorithm provides a coverage solution based on local information gain from side-scan sonar data. At the same time, the solution is generated in such a way that coverage path length is minimized while covering the same area as the standard lawnmower. Upper and lower bounds of the proposed algorithm's improvement compared to the overlap-all-sonar-ranges lawnmower method are estimated analytically and validated through extensive mission parameters variation simulations. Simulation results show that our approach can cut down coverage path length significantly compared to the standard lawnmower method in most application cases.

Signal, image and Synthetic Aperture Radar imagery algorithms in recent time are used in a daily routine. Due to huge data and complexity, their processing is almost impossible in a real time. Often image processing algorithms are inherently parallel in nature, so they fit nicely into parallel architectures multicore Central Processing Unit (CPU) and Graphics Processing Unit GPUs. In this paper image processing algorithms were evaluated, which are capable to execute in parallel manner on several platforms CPU and GPU. All algorithms were tested in TensorFlow, which is a novel framework for deep learning, but also for image processing. Relative speedups compared to CPU were given for all algorithms. TensorFlow GPU implementation can outperform multi-core CPUs for tested algorithms, obtained speedups range from 3.6 to 15 times.
