In this study, multicultural literature served as a site for Chinese Canadians to explore the interplay between their dual cultural backgrounds. After reading a story written by a Chinese Canadian author, participants were invited to imagine a dialogue between two characters with whom they identified, allowing the exploration of different aspects of their bicultural selves. Systematic examination of their dialogues, using cluster analysis of recurrently expressed dialogical themes, revealed four distinct expressive styles (Rhetorical Conflict, Imperative Conflict, Active Narration, and Embodied Reconciliation), each revealing a different bicultural stance. Both the rhetorically probing and explicitly imperative styles of expression reflected a fusion of Chinese and Canadian expectations regarding confrontation, although in different ways each also facilitated the maintenance of a conflictual cultural hierarchy. Active, but distanced, narrative description reflected the preservation of a collective sense of self that is characteristic of traditional Chinese culture. Finally, dialogic enactment of conflicting “voices” allowed reconciliatory, embodied, and generative fusions of Chinese and Canadian cultural expectations.
Six coloured and six non-coloured waxy rice varieties were analyzed by determining amylose, fat, and protein content, pasting, and thermal properties. Significant differences in protein content as well as pasting properties between coloured and non-coloured waxy rice were identified. It was demonstrated that protein may have a main influence on pasting and thermal properties of waxy rice. In addition, the optimal linear relationship between protein and pasting or thermal properties was found by combining RVA and DSC data using Principal component analysis (PCA). Typical indicators, which can classify coloured and non-coloured waxy rice, could be identified by Hierarchical cluster analysis (HCA). In pasting properties, trough and consistency viscosity were typical indicators; in thermal properties, enthalpy and stop temperature were typical indicators.

In this study, six commercial cherry tomato cultivars were analysed for variations in biochemical and technological parameters. Significant differences were observed among cultivars with respect to their technological and functional quality attributes. About 2.48-fold variation in titratable acidity, 2.47-fold variation in total phenolics, 4.13-fold variation in total carotenoid and 7.68-fold variation in lycopene contents were recorded. The total antioxidant activity and respiration rate were also found to vary about 1.85-fold and 1.48-fold, respectively. The highest antioxidant activity and total phenolic content were found in the Cherry tomato hybrid no.1 followed by Pusa cherry tomato-1. Hierarchical cluster analysis revealed that Cherry tomato hybrid no. 1, Pusa cherry tomato-1, and Nagmoti cultivars were abundantly rich in phytochemical and bioactive compounds.

Nine phenolic compounds (gallic acid, (+)catechin, vanillic and caffeic
acid, p-coumaric acid, resveratrol, myricetin, quercitrin and quercetin)
of fourteen Eger (Hungarian) young red wines were investigated using
high-performance liquid chromatography in order to obtain data on the 2003
vintage. The grapes were harvested at different sites of the wine-district,
vinified with same technology, but stored under different conditions (glass
holder or 5-10 years old oak barrel). Same varietal wines originating from
different sites of Eger wine-region showed considerable alterations in some
phenolic components, and we found distinction in polyphenol content of
different varietal wines originating from the same harvesting site. Cluster
analysis was performed to acquire information about the similarity among the
measured wines. Our study provides new data of polyphenol composition for Eger
(Hungary) pure varietal red wines, and the results contribute to better identification
of Hungarian red wines on the basis of geographical location.

Eighty barley genotypes were evaluated for partial resistance components of spot blotch disease of barley caused by Bipolaris sorokiniana under field conditions. Barley genotypes were inoculated with 29 B isolate of Bipolaris sorokiniana and the Area Under Disease Progress Curve (AUDPC), size of lesion, number of lesions leaf−1 and number of spores lesion−1 were recorded for penultimate leaves. A wide range of variation was observed for the components of partial resistance in barley genotypes. AUDPC and size of lesion identified as first principal components for the resistance. Further cluster analysis clustered genotypes into 10 groups and barley genotypes BCU5592, BCU5613, BCU1452, BCU138 and BCU133 exhibited low AUDPC, smaller lesion size, less number of lesions leaf−1 and less number of spores lesion−1. Selecting these genotypes exhibiting resistant components could be helpful in reducing losses caused by disease and thus contribute to increased yield.

The application of commercial rhizobial inoculants to legume crops is proving to be an alternative to synthetic fertilizer use. The challenge for sustainable agriculture resides in the compatibility between crop, inoculants and environmental conditions. The evaluation of symbiotic efficiency and genetic diversity of indigenous rhizobial strains could lead to the development of better inoculants and increased crop production. The genetic variability of 32 wild indigenous rhizobial isolates was assessed by RAPD (Random Amplified Polymorphic DNA). The strains were isolated from red clover (Trifolium pratense L.) nodules from two distinct geographical regions of Northern and Eastern Romania. Three decamer primers were used to resolve the phylogenetic relationships between the investigated isolates. Cluster analysis revealed a high diversity; most strains clustered together based on their geographical location.
Genetic diversity was investigated in a set of eleven hexaploid wheat genotypes originated from CIMMYT, Turkey in comparison with some modern European mostly originated from KWS wheat breeding program using 24 wheat SNP markers. The lowest and highest genetic dissimilarities were observed between genotypes Opus and LDO 330/06, KWS Salix and LDO 330/06, respectively. Based on cluster analysis, 38 wheat genotypes were grouped in two main clusters. Although the grouping pattern is very origin heterogeneous in each group, the grouping pattern of some genotypes appeared to be associated, to some extent. Principal coordinate analysis (PCoA) was used as an alternative way of visualizing the genotypic data. The first, second and third principal components explained 17.79%, 14.39% and 12.24% of the variation, respectively. This study can also be an indicator for breeders to evolve genotypes with diverse genetic background to achieve sustainability in wheat production, to get favorable heterotic combinations in a wheat improvement program.

It has been established that the selected acetamide derivatives fulfill Veber’s and Pardridge’s rule of good bioavailability. The lipophilicity as a crucial molecular descriptor of biological activity for acetamide derivatives was determined by reversed-phase thinlayer chromatography (RP-TLC) in different mixtures of water and organic modifiers (ethanol and tetrahydrofuran). Also, lipophilicity was examined mathematically, by using relevant software packages. The effects of the substituent on the lipophilicity of acetamide derivatives were analyzed. By applying linear regression analysis and 2 multivariate methods (cluster analysis and principal component analysis), the obtained chromatographic parameters, RM0 and m, of the examined acetamides were correlated with the standard measure of lipophilicity, log P, important pharmacokinetic predictors, and selected toxicity parameters. The obtained results confirmed that chromatographic parameters, RM0 and m, determined by RP-TLC, could be successfully used for describing the lipophilicity and estimation of pharmacokinetics and the toxic effects of the studied acetamide derivatives.
This paper examines the impact of EU enlargement and the global economic crisis on the relative development of the EU countries. This effect is assessed by applying multivariate analysis to the whole set of 28 European countries at three representative points in time. The cluster analysis for the years 2002, 2007, and 2012 grouped the countries according to the range of economic development indicators showing within-EU cohesion before the EU enlargement, after the enlargement wave, and after the crisis. The findings show that a decrease in the development differences after the enlargement was replaced with an increase in these differences after the crisis, thus contributing to the existing debate about the success of cohesion and future of European integration. These results are somewhat worrying for the new member states of the EU as well as for EU membership candidates and their prospective development within the integration.

The k0-based internal monostandard neutron activation analysis (IM-NAA) method was used for the analysis of 30 large and non-standard
geometry ancient pottery samples obtained from Buddhist sites of Andhra Pradesh, India. One freshly finished pottery and a
sun-drenched pottery were also analyzed for comparison. Samples were irradiated in thermal column facility of Apsara reactor
and also in graphite reflector position of critical facility of Bhabha Atomic Research Centre. Radioactive assay was carried
out using a 40% relative efficiency HPGe detector coupled to MCA. Concentration ratios of 15 elements with respect to Sc were
determined. The La/Ce values as well as statistical cluster analysis utilizing concentration ratios of elements were used
for grouping/provenance of the potteries.
