Fashion inspired by local culture references is our starting point for understanding how fashion, as a contemporary and dynamic dimension, can preserve the capacity of representing and maintaining local traditions. Through an interpretive approach, we look at the relationship between traditional clothing preservation and the creation of a contemporary fashion associated with the gaucho traditionalist culture in southern Brazil. The study counts on 22 indepth interviews with consumers and producers of the traditional and contemporary gaucho fashion movement, as well as document analysis and netnographic data exploration on gaucho traditions. Results indicate that even facing the resistance from conservative groups that aim to keep clothing stable over time, fashion producers and consumers associated the contemporary gaucho clothes as a modern mechanism for tradition preservation. It allows the adjustment of tradition representation in line with changes in social roles, especially gender patterns. Findings reveal that contemporary gaucho fashion challenges the rigid conception of tradition, once it represents a democratic instrument able to supply a sense of belonging adjusted to contemporary time. Finally, we theorize about the ability of symbolic representations of a particular culture to be transferred to emerging fashion elements over time, without losing the bond with the local tradition.

The aim of this study was to explore the accuracy and feasibility of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) in identifying bacteria from environmental sources, as compared with rpoA gene sequencing, and to evaluate the occurrence of bacteria of the genus Enterococcus in wild birds. In addition, a phyloproteomic analysis of certain Enterococcus species with spectral relationships was performed. The enterococci were isolated from 25 species of wild birds in central Europe (Poland). Proteomic (MALDI-TOF MS) and genomic (rpoA gene sequencing) methods were used to identify all the isolates. Using MALDI-TOF MS, all 54 (100%) isolates were identified as Enterococcus spp. Among these, 51 (94.4%) isolates were identified to the species level (log(score) ≥2.0), and three isolates (5.6%) were identified at a level of probable genus identification (log(score) 1.88-1.927). Phylogenetic analysis based on rpoA sequences confirmed that all enterococci had been correctly identified. Enterococcus faecalis was the most prevalent enterococcal species (50%) and Enterococcus faecium (33.3%) the second most frequent species, followed by Enterococcus hirae (9.3%), Enterococcus durans (3.7%), and Enterococcus casseliflavus (3.7%). The phyloproteomic analysis of the spectral profiles of the isolates showed that MALDI-TOF MS is able to differentiate among similar species of the genus Enterococcus.

We report on the measurement of the absolute external luminescence quantum efficiency that is directly accessible using a miniature integrating sphere fitted into a cryostat. Various measurements have been carried out on high quality laboratory bulk samples and dierent commercially available ZnO powders from 10 K up to room temperature. A fit to the temperature dependent quantum efficiency shows the existence of various activated processes.

Room-Temperature Stimulated Emission in ZnO: Doubts on Excitonic Lasing

Concerning stimulated emission, we discuss for ZnO the roles of excitonic processes and of re- combination in an inverted electron-hole plasma. While excitonic processes are well justied at lower temperatures and densities, doubts arise concerning the concept of excitonic lasing in ZnO at or even above room temperature. The densities at laser threshold and at room temperature are frequently at or above the Mott density, but below the density at which population inversion is reached. We suggest alternative processes in a non-inverted plasma.

By using a catalyst-assisted vapor phase deposition method, we recently fabricated high-quality ordered ZnO nanorod arrays with uniform rod size. The rods, grown perpendicularly on GaN/Al2O3 substrates, were [0001]-oriented single crystals with diameters of 200 nm, length of 4.7 µm, and rod-to-rod spacings of 500 nm. The growth conditions, including the choice of the substrate, the patterning of the catalyst on the substrate, and the growth parameters, played important roles in determining the morphology of the rods, and the best samples were produced under optimized conditions. Time-resolved micro-photoluminescence measurements on single nanorods demonstrated laser emission at temperatures up to room temperature. These high-crystal-quality nanorod arrays may be promising candidates for ultraviolet nanolaser arrays.
Microscopic Origin of the Near-Band-Edge Emission in Aqueous Chemically-Grown ZnO Nanorods

The microscopic origin of the near-band-edge emission in low-temperature aqueous chemicallygrown ZnO nanorods is analyzed. For the as-grown nanorods, a broad and almost featureless main emission band at 3.366 eV is observed due the presence of a high donor and defect density. After the nanorods have been annealed at 800 ℃ for 1 hour in an oxygen atmosphere, a remarkable reduction of the linewidth of the near-band-edge emission from 10 meV to 4 meV is observed. Sharp and distinguishable excitonic transitions are visible. Time-resolved photoluminescence measurements show very fast recombination times of 11 ps for the as-grown sample while the radiative recombination time increases to 80 ps after the sample is annealed in oxygen atmosphere.
