Oscillatory Behavior of Critical Amplitudes of the Gaussian Model on a Hierarchical Structure

We studied oscillatory behavior of critical amplitudes for the Gaussian model on a hierarchical structure presented by a modified Sierpinski gasket lattice. This model is known to display non-standard critical behavior on the lattice under study. The leading singular behavior of the correlation length $\xi$ near the critical coupling $K=K_c$ is modulated by a function which is periodic in $\ln|\ln(K_c-K)|$. We have also shown that the common finite-size scaling hypothesis, according to which for a finite system at criticality $\xi$ should be of the order of the size of system, is not applicable in this case. As a consequence of this, the exact form of the leading singular behavior of $\xi$ differs from the one described earlier (which was based on the finite-size scaling assumption).Comment: 9 pages (REVTEX), 2 figures (EPS), Phys.

Antifungal Activity and Inhibitory Effect on Urease of Some Organo-Mercuric Compounds

A number of aliphatic and aromatic organo-·mercuric compounds of the general formula R-Hg-X, in which R represents a n organic radical and X an anionic radical, were prepared. The antifungal and inhibitory effect of the tested compounds was compared by app ly1ng the aiuxa nographic diffusion method and by measuring the degree of inhibition of urease. It was found that the antifungal activity d epends mainly on the organic radical R and that the antonic radical h as no effect on fungitoxicity

Ambulatory assessment of language use: Evidence on the temporal stability of Electronically Activated Recorder and stream of consciousness data

The ambulatory assessment offers a wide range of methods enabling researchers to investigate psychological, behavioral, emotional, and biological processes. These methods enable us to gather data on individual differences in language use for psychological research. Two studies were conducted with an aim to evaluate and compare the temporal stability of language measures extracted by LIWC software form data obtained by two frequently used methods for assessment of language use, i.e., Electronically Activated Recorder (EAR) and stream of consciousness (SOC) task. Additionally, we examined the amount of variance in language use (assessed by both methods) that can be attributed to intra-individual variability and stable individual differences. Study 1 was focused on investigating language use obtained from 74 respondents using the EAR for 3 consecutive days. Study 2 was conducted on 250 respondents participating in a SOC task where verbal production was collected at ten time points over a 2-month period. Results show that measures obtained using the SOC task have higher temporal stability and consistency, and to a certain extent enable better detection of individual differences. Taking into account certain situational variations improves the reliability of EAR measures

Psychometric evaluation of the Serbian dictionary for automatic text analysis - LIWCser

LIWC (Linguistic Inquiry and Word Count) is widely used word-level content analysis software. It was used in large number of studies in the fields of clinical, social and personality psychology, and it is adapted for text analysis in 11 world languages. The aim of this research was to validate empirically newly constructed adaptation of LIWC software for Serbian language (LIWCser). The sample of the texts consisted of 384 texts in Serbian and 141 texts in English. It included scientific paper abstracts, newspaper articles, movie subtitles, short stories and essays. Comparative analysis of Serbian and English version of the software demonstrated acceptable level of equivalence (ICCM=.70). Average coverage of the texts with LIWCser dictionary was 69.93%, and variability of this measure in different types of texts is in line with expected. Adaptation of LIWC software for Serbian opens entirely new possibilities of assessment of spontaneous verbal behaviour that is highly relevant for different fields of psychology

Experimental determination and modeling of the volumetric properties, refractive indices and viscosities of the volumetric properties, refractive indices and viscosities of the multicomponent organic solvent mixtures

U ovoj doktorskoj disertaciji izvršeno je eksperimentalno merenje gustine ρ, indeksa refrakcije nD i viskoznosti η osam binarnih i četiri ternerna sistema na atmosferskom pritisku i u temperaturnom intervalu od 288.15 K do 323.15 K sa korakom od 5 K. Izabrani su binarni sistemi: dimetiladipat + 1-butanol, dimetiladipat + 2-butanol, dimetiladipat + 2-butanon, dimetiladipat + tetrahidrofuran, 2-butanon + 1-butanol, 2- butanon + 2-butanol, tetrahidrofuran + 1-butanol, tetrahidrofuran + 2-butanol, i ternerni sistemi: dimetiladipat + 2-butanon + 1-butanol, dimetiladipat + 2-butanon + 2-butanol, dimetiladipat + tetrahidrofuran + 1-butanol i dimetiladipat + tetrahidrofuran + 2- butanol. Eksperimentalna merenja izvršena su na digitalnom gustinomeru Anton Paar DMA 5000, refraktometru Anton Paar RXA 156 i viskozimetru Anton Paar SVM 3000. Na osnovu eksperimentalno izmerenih vrednosti ρ, nD i η, izračunate su vrednosti dopunske molarne zapremine VE, promene indeksa refrakcije ΔnD i promene viskoznosti Δη pri mešanju. Eksperimentalni podaci obrađeni su pomoću empirijskih jednačina Redlich-Kister i Nagata-Tamura. Uspešnost predviđanja vrednosti VE, ΔnD i Δη ternernih sistema ispitana je primenom empirijskih modela polinomskog tipa: Radojković, Kohler, Jacob-Fitzner, Colinet, Tsao-Smith, Toop, Scatchard i Rastogi. Modelovanje volumetrijskih svojstava obuhvatilo je: korelisanje vrednosti VE binarnih sistema, kao i korelisanje i predviđanje vrednosti VE ternernih smeša pomoću Peng- Robinson-Stryjek-Vera kubne jednačine stanja (PRSV CEOS) kombinovane sa modelima za dopunsku Gibbs-ovu energiju (CEOS/GE) u koje su ugrađena dva pravila mešanja, van der Waals jedan fluid (vdW1) i model razvijen od strane Twu i saradnika (TCBT). Na osnovu vrednosti nD čistih komponenata, izvršeno je predviđanje vrednosti VE, kao i predviđanje vrednosti nD binarnih sistema, korišćenjem Lorentz-Lorentz, Dale-Gladstone, Eykman, Arago-Biot, Newton i Oster pravila mešanja. Izvršen je pregled i testiranje 43 korelativne metode za izračunavanje vrednosti viskoznosti. Za modelovanje η binarnih sistema korišćene su dve grupe modela: korelativni (Teja-Rice, McAllister 3 i McAllister 4) i prediktivni (UNIFAC-VISCO). Prilikom predviđanja vrednosti η UNIFAC-VISCO modelom, na osnovu eksperimentalnih merenja, optimizacionim metodama određene su nove vrednosti interakcionih parametara...In this dissertation, densities ρ, refractive indices nD and viscosities η of eight binary and four ternary systems were experimentally measured at atmospheric pressure and at temperatures between 288.15 K and 323.15 K with a 5 K temperature increment. The following binary and ternary systems were selected: dimethyladipate + 1-butanol, dimethyladipate + 2-butanol, dimethyladipate + 2-butanone, dimethyladipate + tetrahydrofuran, 2-butanone + 1-butanol, 2-butanone + 2-butanol, tetrahydrofuran + 1- butanol, tetrahydrofuran + 2-butanol, and dimethyladipate + 2-butanone + 1-butanol, dimethyladipate + 2-butanone + 2-butanol, dimethyladipate + tetrahydrofuran + 1- butanol and dimethyladipate + tetrahydrofuran + 2-butanol. Experimental measurements were conducted on digital densimeter Anton Paar DMA 5000, refractometer Anton Paar RXA 156 and viscometer Anton Paar SVM 3000. Experimentally measured ρ, nD and η were used in calculation of the excess molar volumes VE, deviations of refractive indices nD and viscosity deviations . Experimental data were correlated by the Redlich-Kister and Nagata-Tamura equations. Prediction quality for the VE, nD and of the ternary systems was evaluated using the empirical polynomial models developed by: Radojković, Kohler, Jacob-Fitzner, Colinet, Tsao-Smith, Toop, Scatchard and Rastogi. Modeling of the volumetric properties included correlation of the binary, as well as the correlation and prediction of the ternary VE values, using the Peng-Robinson-Stryjek-Vera cubic equation of state (PRSV CEOS) combined with models for the excess Gibbs energy (CEOS/GE) and two mixing rules: van der Waals one fluid (vdW1) and the mixing rule developed by Twu et al. (TCBT). Refractive indices of the pure components were used for the prediction of VE and nD of the binary mixtures using the Lorentz-Lorentz, Dale-Gladstone, Eykman, Arago-Biot, Newton and Oster mixing rules. 43 viscosity correlation methods were analyzed and tested. Modeling of the η of the binary systems encompassed the application of the correlative (Teja-Rice, McAllister 3 and McAllister 4) and predictive (UNIFAC-VISCO) models. Prediction of η by the UNIFAC-VISCO model included optimization of the experimental data to develop the new interaction parameters of the UNIFAC-VISCO model..

Militant Extremist Mindset in Post-conflict Regions of the Balkans

This study explores the structure of Militant Extremist Mindset (MEM) within a sample of participants living in areas with enhanced risk of intergroup conflict. We were also interested in comparing members of three different ethnic groups (Serbs, Albanians, and Bosniaks) on MEM measures. A short version of the MEM scale was created for future use. We found that the factorial structure of MEM was replicated in the sample composed of people from both sides of a conflict. Ethnic groups did not differ significantly on the Grudge component of MEM. Group differences were pronounced on the Pro-violence and Utopianism factors. Albanians scored higher than Bosniaks and Serbs on these two dimensions. However, significant differences were obtained on the Ethos of Conflict (EOC) factor when groups of Serbs living within and outside areas of recent conflict were compared

Double Tooth

The form of primary and permanent teeth can differ morphologically from that which is considered normal, completely or in some parts. The changes in tooth form can be hereditary or caused by some disease or trauma. Fusion is a union of one or more teeth during development. Gemination means that two separate morphological units were created by division of the tooth germ. The intention of this study was to state the prevalence of double teeth (fusion and gemination) among the persons tested, as to gender, distribution in the maxilla or mandible, and whether the anomaly occurred bilaterally or unilaterally. The results of this investigation have shown that in a total of examined 3,517 plaster models, a prevalence of double teeth was 0.2%. 57.2% of them were fusioned and 42.9% geminated
