Structure of Dark Triad Dirty Dozen Across Eight World Regions

The Dark Triad (i.e., narcissism, psychopathy, Machiavellianism) has garnered intense attention over the past 15 years. We examined the structure of these traits’ measure—the Dark Triad Dirty Dozen (DTDD)—in a sample of 11,488 participants from three W.E.I.R.D. (i.e., North America, Oceania, Western Europe) and five non-W.E.I.R.D. (i.e., Asia, Middle East, non-Western Europe, South America, sub-Saharan Africa) world regions. The results confirmed the measurement invariance of the DTDD across participants’ sex in all world regions, with men scoring higher than women on all traits (except for psychopathy in Asia, where the difference was not significant). We found evidence for metric (and partial scalar) measurement invariance within and between W.E.I.R.D. and non-W.E.I.R.D. world regions. The results generally support the structure of the DTDD

Qualitative analysis of hexane flour extract of spelt

Gas chromatography with mass spectrometry (GC-MS) was used for performing a qualitative analysis of the hexane flour extract of three samples of spelt. All the three samples were first treated with hexane and the obtained extracts were used for the analysis of the fatty acid lipid components. The transesterification reaction was performed using TMSH (trimethylsulfonium hydroxide, 0.2M in methanol), and the fatty acids were esterified from acylglycerol to methyl-esters. In all analyzed extracts, the predominant component was methyl linoleate, followed by methyl oleate and methyl palmitate. The subsequent tests, performed by cluster analysis, were used to compare the hexane flour extracts of different types of spelt. [Projekat Ministarstva nauke Republike Srbije, br. III46005 i br.

Disintegration as an Additional Trait in the Psychobiological Model of Personality Assessing Discriminant Validity via Meta-Analysis

This meta-analytic study investigates the relations between Disintegration-like phenomena (i.e., various aspects of symptomatology with the prefix "schizo-," both at the clinical and the subclinical level) and the traits of the Psychobiological Model of Personality (PBMP). The empirically based benchmark for assuming the distinctness of the trait Disintegration was .30. The sample included 26 manuscripts with 30 studies and 424 effect sizes. By computing inverse sampling variance weighted mean correlation coefficients under a random-effects assumption, the following associations were found between Disintegration and Harm Avoidance, Novelty Seeking, Reward Dependence, Persistence, Self-Directedness, Cooperativeness, and Self-Transcendence: .23, .04, -.15, -.02, -.23, -.16, and .17, respectively. Two variables were found to moderate the Disintegration-Self-Transcendence correlation. Despite the theoretical expectation and some empirical evidence that Self-Transcendence (and other character traits) should capture variations in Disintegration-like phenomena, our results suggest that schizo-type phenomena are not adequately covered by the PBMP

Application of Peleg model to study mass transfer during osmotic dehydration of apple in sugar beet molasses

The applicability of Peleg equation was examined for the description of mass transfer during osmotic dehydration (OD) of apple in sugar beet molasses. Mass transfer was investigated in terms of water loss (WL) and solid gain (SG), during OD in 40-80% sugar beet molasses solutions, at 45, 55 and 65ºC. High regression coefficients obtained for Peleg constants (R2>0.975) indicate good fit to the experimental data. The Peleg rate constant varied from 0.144 to 0.785 (g/g i.s.w.) and from 2.006 to 4.436 (g/g i.s.w.) for WL and SG, respectively. The Peleg capacity constant varied from 1.142 to 1.553 (h g/g i.s.w.) and from 8.254 to 11.930 (h g/g i.s.w.) for WL and SG, respectively. The equilibrium WL∞ and SG∞ were estimated using the Peleg model. In addition, the activation energy (Ea) for WL and SG was determined from the relationship between the Peleg rate constant and Arrhenius equation

Mycobiota of Serbian wheat grain in 2010

This research focused on the assessment of the infection level of sampled wheat grains with phytopathogenic fungi. The samples were taken from the localities Rimski Šančevi and Sombor. The research investigated the impact of localities to intensity of fungal infection by fungi from genus Fusarium and Alternaria. Isolates from genus Fusarium and Alternaria were determined to species level. Pathogenicity of Fusarium and Alternaria isolates from different localities to wheat seedlings was also established.

The effect of fungicide treatment on mycotoxin content and yield parameters of wheat

Effects of treatment with triazole fungicide were evaluated on 14 wheat genotypes with respect to mycotoxin (aflatoxins, ochratoxin A and deoxynivalenol), yield, 1000 kernel weight and hectoliter weight. Mycopopulation of seed samples was also determined. According to the results, fungicide treatment can reduce the level of mycotoxins in seed samples in order to improve the quality parameters and reduce the level of fungal contamination
