25. “Penumbra sign” of Brodie's abscess
ABSTRACT In this study, 55 tomato genotypes from different geographical regions were evaluated with ISSR markers (Inter Simple Sequence Repeats). The seven ISSR primers originated 63 amplified bands, of which 90.48% were polymorphic. The cluster analysis based on the Nei-Li similarity coefficient using the average genetic clustering method (UPGMA) revealed t

27. Soil seed bank in a subtropical grassland under different grazing intensities
ABSTRACT Grazing is an important determinant for the composition and structure of grasslands; however, soil seed bank (SSB) response to grazing intensity is poorly investigated. We analyzed SSB richness and density in a subtropical grassland in southern Brazil with different forage offers (low, intermediate, high and very high), that is, contrasting grazing

28. Was „eine Mädchen”, „eins Mädchen” und „Ø Mädchen” gemein haben: Zur Relevanz sprachtypologischer Korrelationen beim Transfer in die L2 Deutsch aus typologisch unterschiedlichen Sprachen
Abstract Whether for exchanging interpersonal needs -such as thoughts- or for business purposes -as in the case of the Lingua franca- in its specific form language has always been presumed to be the human species’ means for communication. With the concurrent rise in demand for multilingualism in the 20th century, studies examining language acquisition have

29. Dermoscopic pattern of Kyrle's disease,
Abstract The clinical diagnosis of Kyrle's disease may sometimes be challenging, due to the clinical similarity of lesions to other pruritic dermatosis. Although the dermoscopy is being increasingly used in daily practice, there is insufficient data in literature describing the dermoscopic patterns of Kyrle's disease, since only one report has been published

30. A Selective Gas Chromatography-Selected Ion Monitoring Mass Spectrometry (GC-MS/SIM) Method to Determine Polychlorinated Biphenyls in Fuller’s Earth
Polychlorinated biphenyls (PCBs) are carcinogenic to humans and can be found in Fuller’s earth used for the regeneration of used transformer oil. This work describes a highly selective gas chromatographic-selected ion monitoring mass spectrometric method (GC-MS/SIM) for the simultaneous determination of three Aroclor PCB congener mixtures (1242, 1254, and

31. Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest
ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonizatio

32. TD-DFT Analysis of the Dissymmetry Factor in Camphor
The fact that the dissymmetry lgeb (g-factor) of camphor is large has been known for decades, and the interpretation of the observed data has also been known for a long time. However, due to the ability of quantum chemical methods to describe chiroptical phenomena more appropriately, additional approaches based on these methods have been successful employed.

33. CHEMICAL VARIABILITY OF Allamanda cathartica L. FLOWERS ASSESSED BY MULTIVARIATE DATA ANALYSIS
The aim of this study was to determine the chemical variability of Allamanda cathartica flowers collected in different localities of Santa Catarina State, Brazil. Extractive solutions (25 samples) were analyzed by HPLC-DAD for the qualitative and quantitative profiles of the iridoid plumieride, the flavonoid rutin as well as total flavonoid content expressed

34. Multistage Phase Decomposition Behavior and Kinetics for Zr65Ni30Pd5 Ternary Amorphous Alloy
We have examined heating-induced phase decomposition and its kinetics for Zr65Ni30Pd5 amorphous alloy in an argon atmosphere. The amorphous phase decomposes through three stages in the order of amorphous → icosahedral quasicrystal (I-Q) + amorphous → approximant cubic Zr2(Ni,Pd) → tetragonal Zr2Ni + tetragonal Zr2Pd phases. The approximant crystalline

35. Diagnóstico e tratamento da síndrome do choque tóxico estreptocócico em unidade de terapia intensiva pediátrica: relato de caso
RESUMO Dentre as infecções causadas por Streptococcus β hemolyticus do grupo A de Lancefield, talvez a síndrome do choque tóxico seja a mais grave, com alto índice de mortalidade. A semelhança clínica com outras formas de choque, principalmente séptico, pode, muitas vezes, confundir o avaliador e interferir na escolha da terapêutica mais adequada.

36. NUMERICAL AND EXPERIMENTAL INVESTIGATION OF AIR-WATER SYSTEM TO SIMULATE BUBBLE DYNAMICS IN LIQUID SODIUM POOL
Abstract The dynamics of rising bubbles in a liquid sodium pool plays a significant role in the estimation of the radiological source term during anticipated transients and normal operation of a fast reactor. Sodium is chemically reactive with air and water. Therefore, carrying out experiments using sodium on a reactor scale level requires extra precautions.
