Description of the immature stages of the weevil Anthonomus vis Clark (Coleoptera, Curculionidae), inquiline into the gall of Leandra aurea (Melastomataceae). The third instar larva and the pupa of Anthonomus vis Clark, 1992 are described and illustrated, based upon specimens collected in the Serra de São José, Tiradentes, in Minas Gerais, southeastern Brazil. The species was previously known from the type series collected in the states of Amapá and Pará. Comparisons with the larva and pupa of A. grandis Boheman, 1843 and A. monostigma Champion, 1903 are included. The larvae of A. vis live as inquilines in the galls induced by a species of momphid moths (Lepidoptera, Momphidae) in the stems of Leandra aurea (Cham.) Cogn. (Melastomataceae).

Miniature diffusion size classifiers (miniDiSC) are novel handheld devices to measure ultrafine particles (UFP). UFP have been linked to the development of cardiovascular and pulmonary diseases; thus, detection and quantification of these particles are important for evaluating their potential health hazards. As part of the UFP exposure assessments of highwaymaintenance workers in western Switzerland, we compared a miniDiSC with a portable condensation particle counter (P-TRAK). In addition, we performed stationary measurements with a miniDiSC and a scanning mobility particle sizer (SMPS) at a site immediately adjacent to a highway. Measurements with miniDiSC and P-TRAK correlated well (correlation of r = 0.84) but average particle numbers of the miniDiSC were 30%âeuro"60% higher. This difference was significantly increased for mean particle diameters below 40 nm. The correlation between theminiDiSC and the SMPSduring stationary measurements was very high (r = 0.98) although particle numbers from the miniDiSC were 30% lower. Differences between the three devices were attributed to the different cutoff diameters for detection. Correction for this size dependent effect led to very similar results across all counters.We did not observe any significant influence of other particle characteristics. Our results suggest that the miniDiSC provides accurate particle number concentrations and geometric mean diameters at traffic-influenced sites, making it a useful tool for personal exposure assessment in such settings.

A expansão da cultura da soja evidenciou uma alta especificidade hospedeira, requerendo a pesquisa de novas estirpes que apresentassem capacidade de nodular a soja e bom potencial de competição com a população de rizóbios naturalizada nos solos. O objetivo deste trabalho foi avaliar a especificidade hospedeira de variantes isolados de estirpes de Bradyrhizobium spp quanto à nodulação e eficiência relativa de fixação de N2 atmosférico em soja (cvs peking e clark), caupi e guandu. O experimento foi realizado sob condições controladas em câmara de crescimento por meio de testes de variantes de B. japonicum e B. elkanii e suas respectivas estirpes originais quanto à habilidade de nodular soja, caupi e guandu. A colheita foi realizada aos 35 dias, sendo avaliada a nodulação (número, peso dos nódulos secos), produção de matéria seca na parte aérea, eficiência relativa de fixação de N2 atmosférico. Os variantes e estirpes de Bradyrhizobium spp nodularam Glycine max (cultivares BR-16, Clark e Peking), Vigna unguiculata e Cajanus cajan, contudo, apenas para Glycine max a interação rizóbio-leguminosa demonstrou eficiência simbiótica significativa.

The influence of premetallization surface preparation on the structural, chemical, and electrical properties of Au-nGaN interfaces has been investigated by x-ray photoemission spectroscopy (XPS), current-voltage measurement (I-V) and cross-section transmission electron microscopy (TEM). XPS analysis showed that the three GaN substrate treatments investigated i.e., ex situ hydrofluoric acid etch, in situ anneal in ultrahigh-vacuum (UHV), and in situ Ga reflux cleaning in UHV result in surfaces increasingly free of oxygen contamination. XPS and TEM characterization of Au-nGaN formed after the three premetallization surface treatments show that HF etching and UHV annealing produce abrupt, well-defined interfaces. Conversely, GaN substrate cleaning in a Ga flux results in Au/GaN intermixing. I-V characterization of Au¿nGaN contacts yields a Schottky barrier height of 1.25 eV with a very low-ideality factor and very good contact uniformity for the premetallization UHV anneal, while the Ga reflux cleaning results in a much lower barrier (0.85 eV), with poor ideality and uniformity. I-V and XPS results suggest a high density of acceptor states at the surface, which is further enhanced by UHV annealing. These results are discussed in the context of current models of Schottky barrier formation.
