Metode: Kefalogrami 211 pacijenata snimljeni su i spremljeni u digitalnom obliku. Nakon toga su, s pomocu posebno razvijenog softvera i tih pohranjenih radiograma, specijalisti ortodoncije oznacili i mjerili za svakog pacijenta nekoliko karakteristicnih kefalometrijskih obilježja. Rezultati su bili potrebni za automatsko određivanje stupnja sazrijevanja vratnih kralježaka s nekoliko numerickih tehnika, među kojima K znaci klasteriranje (grupiranje), a Fuzzy C – dusteriranje (rasipanje). Rezultati su uspoređeni s podacima koje su dobili specijalisti. Rezultati: Najbolji rezultati dobiveni su koristenjem Fuzzy C rasipanja. Tocna ocjena stupnja CVM-a iznosila je oko 70 posto, a procjena klase bila je visa od 99 posto. Zakljucak: Eksperimentalni rezultati pokazuju da se može razviti potpuno automatizirani sustav za procjenu i predviđanje stupnjeva CVM-a, premda jos treba rijesiti manje teskoce prije primjene u klinickoj praksi.
The solubility enhancement of diazepam and nitrazepam in water was analyzed depending on temperature and amount of α-cyclodextrin ( α-CD), β-cyclodextrin (β-CD) and 2-hydroxypropyl-β-cyclodextrin (2-HP-β-CD). The interactions of drug-cyclodextrin in solution were investigated by the phase-solubility analysis. Diazepam (nitrazepam) content in aqueous complexation medium was analyzed UV spectrophotometrically. Classical solubility data were used to derive apparent stability constants (K1:1) which were used to derive thermodynamic parameters for the diazepam (nitrazepam)-cyclodextrin complexes. Since all phase solubility plots were of AL–types, and calculated Slopes after linear regression analysis were found to be less than 1, it could be assumed that stoichiometry of the formed binary systems was 1:1. According to the calculated K1:1 values, the stability of the complexes of diazepam and nitrazepam with a-CD, β-CD and 2-HP-β-CD varies as follows: 2-HP-β-CD > β-CD > β-CD. The a-CD has higher affinity for dissolving nitrazepam compared to diazepam. While all parameters lead to an improvement in solubility, the largest effect was obtained for guest-host complexation with 2-HP-β-CD. The solubility of diazepam and nitrazepam in water increased 93.02 times and 64.23 times, respectively, in the presence of 40% (w/w) 2-HP-β-CD, at 25°C. Solubility data for diazepam and nitrazepam in aqueous 2-HP-b-CD were used to derive thermodynamic parameters, ΔG° at 298 K = –14.43 kJ·mol–1, ΔH° = 0.79 kJ·mol–1, ΔS° at 298 K = 51.17 J·mol–1·K–1 and ΔG° at 298 K = –13.43 kJ·mol–1, ΔH° = 2.38 kJ·mol–1, ΔS° at 298 K = 53.01 J·mol–1·K–1, respectively. Formation of inclusion complexes substantially increases the water solubility of diazepam and nitrazepam. Diazepam and nitrazepam dissolution thermodynamics in aqueous 2-HP-β-CD were characterized by spontaneous and endothermic dissolution and hydrophobic interactions.
The aim of this paper is to examine the extent and impact of the global financial crises on position of the banking sector of Western Balkans covering both pre-crisis and crisis period as well as to provide an explanation for these trends.This paper deals with cross-country comparison analysis of banking in Western Balkans before and during crises. Although, depth of the crisis in the banking sector of Western Balkans is not yet fully evident, selected indicators in this paper point to its direction. The research alone has determined the paper’s structure which consist an analysis of the impact of the global financial crisis on recent occurrences in the banking of the region.Impact of global financial crises has been transmitted on the position banking sector selected countries through several sources, especially through: impact profitability, credit growth has dropped significantly and asset quality has deteriorated markedly.Although the economies of Western Balkan countries in crisis period performed differently the results of the comparison show that the global financial crisis has a substantial impact on the banking sector of the region.
According to the number of published research studies, Cattell's 16PF Inventory is the most commonly used tool for exploration of 'normal' personality ever. Besides confirmed cross-cultural validation and standardization on a very large number of respondents, from the early start this inventory was followed with a controversy regarding its factorial structure, especially its second-order factors. The ambiguity among studies that examined the 16PF leads us to the problem of this research which is evaluation of general factors of the 16PF personality inventory-5th edition. The main goal of this research is to explore the factorial structure of the second-order factors congruent with Cattell’s hypothesis. The research was conducted on a sample of students from Tuzla and Sarajevo (N = 512, average age M = 21.74; SD = 3.72). The 16PF showed relatively modest psychometric properties on first-order factors level. Reliability coefficients varied between α = .47 and α = .73. Only H and Q2 factors have satisfactory reliability. The second-order factor analysis, using promax rotation, extracted 4 factors which accounted for 54% of variance. The first factor, accounting for about 20% of variance, could be identified as Anxiety. The second factor, accounting for about 13% of variance, conditionally corresponds to Self-Control factor. The third factor accounts for about 11% of variance and can be conditionally designated as Extroversion. The fourth factor accounts for 10% of variance and is most similar to Cattell’s factor of Independence. Cattell’s fifth factor, Tough- Mindedness, was not confirmed. We can conclude that the 16PF in general has very poor psychometric properties, and that the factorial structure proposed by the authors was not entirely confirmed.
Inspired by the recent developments in modeling and analysis of reaction networks, we provide a geometric formulation of the reversible reaction networks under the influence of diffusion. Using the graph knowledge of the underlying reaction network, the obtained reaction-diffusion system is a distributed-parameter port-Hamiltonian system on a compact spatial domain. Motivated by the need for computer-based design, we offer a spatially consistent discretization of the PDE system and, in a systematic manner, recover a compartmental ODE model on a simplicial triangulation of the spatial domain. Exploring the properties of a balanced weighted Laplacian matrix of the reaction network and the Laplacian of the simplicial complex, we characterize the space of equilibrium points and provide a simple stability analysis on the state space modulo the space of equilibrium points. The paper rules out the possibility of the persistence of spatial patterns for the compartmental balanced reaction-diffusion networks.
Pomological characterisation of pears of the so-called “Lubenicarka” (watermelon pear) group has been based on three genotypes identified in numerous vegetative progeny as part of the native assortment of Bosnia and Herzegovina. “Krupna Lubenicarka” (common watermelon pear) variety was recommended for the expansion of production at the beginning of the XX century, and there were two more genotypes (“Crna Lubenicarka” (black watermelon pear) and “Bijela Lubenicarka” (white watermelon pear)) that were listed under the common name of “Lubenicarka”. The research results show that “Krupna Lubenicarka” variety has vegetative progeny characterised by stable pomological features which clearly and reliably determine this variety. “Crna” and “Bijela Lubenicarka” genotypes are characterised by certain pomological distinctions that clearly make them different, but also by some similarities, whose variability raises up the question of their reliable pomological and genetic characterisation. Morphometric analyses of the fruit and leaf of “Krupna Lubenicarka” variety and “Crna” and “Bijela Lubenicarka” genotypes represent their first pomological characterisation that can be adopted as a reliable foundation for collecting, further pomological studies and genetic characterisation.
A previous study of ours (Koso & Hansen, 2006) indicated remarkably large decrements in neuropsychological functioning in Bosnian war veterans with posttraumatic stress syndrome (PTSD). The present study assessed attention (Sustained Attention to Response Task), executive function (Trail Making Test), and memory (Rivermead Behavioural Memory Test) in an additional group of veterans with (n = 45) or without (n = 34) PTSD. Replicating our prior study, sizeable performance decrements were observed. Furthermore, multivariate analyses revealed that (a) good verbal IQ partly buffered against the harmful effect of PTSD on more fluid cognitive functions, (b) cognitive impairment was related to PTSD symptom severity (Posttraumatic Diagnostic Scale scores) and to (c) difficulties in everyday cognitive functioning (Cognitive Failures Questionnaire scores).
