Efeito da aplicação de inseticidas na floração da macieira sobre Apis mellifera L. (Hymenoptera: Apidae).

Os inseticidas Bacillus thuringiensis (Dipel 100mL.100L-1) e Novaluron (Rimon 100 CE 40 ml.100L-1) são registrados para o controle de Lepidoptera na cultura da macieira. O objetivo deste trabalho foi avaliar o efeito da aplicação destes inseticidas no período de floração da macieira sobre Apis mellifera. O experimento foi conduzido na safra 2014/2015 em Fraiburgo, SC, utilizando pomares de macieira com 5 hectares

Many experimental studies have been done to understand the best characteristics of cells, materials and laboratory methods for safe clinical applications. The aim of this study was to compare the ability of 2 different human demineralized bone matrices (DBMs), the one enriched and the other not enriched with hyaluronic acid, to stimulate in vitro the proliferation and the osteogenic differentiation of human adipose-derived stem cells (ADSCs) seeded onto an osteoconductive scaffold. Materials and Methods: ADSCs were isolated, by enzymatic digestion, from abdominal adipose tissue of 5 patients undergoing cosmetic lipoaspiration surgery. ADSCs were then seeded onto a 3D scaffold in the presence of the two different osteoinductive matrices of human demineralized bone and evaluated for proliferation and osteogenic differentiation. The safety of the methods was verified using array-Comparative Genomic Hybridization (array-CGH). Results: ADSCs were able to differentiate in osteogenic sense. Both DBMs showed the ability to induce osteogenic differentiation of the cells. Conclusion: array-CGH showed no changes at genome level, thus confirming the safety of materials and method

Controle de pássaros e insetos frugívoros e manutenção da qualidade da uva com uso de tela.

A incidência de pássaros frugívoros, como o tico-tico (Zonotrichia capensis), o azulinho (Cyanoloxla glacocaerulea), o sabiá (Turdus rufiventris rufiventris), entre outros, em vinhedos Comerciais da região do Alto Vale do Rio do Peixe é um problema permanente para os viticultores Estas aves, além de ocasionar danos diretos às uvas, potencializam o ataque de insetos (principalmente abelhas e vespas), os quais encontram no resíduo do suco extravasado pelo rompimento da baga, uma importante fonte alimentar num período de escassez de recursos..Resumo

The VISCACHA survey -- V. Rejuvenating three faint SMC clusters

We present the analysis of three faint clusters of the Small Magellanic Cloud RZ82, HW42 and RZ158. We employed the SOAR telescope instrument SAM with adaptive optics, allowing us to reach to V~23-24 mag, unprecedentedly, a depth sufficient to measure ages of up to about 10-12Gyr. All three clusters are resolved to their centres, and the resulting colour-magnitude diagrams (CMDs) allow us to derive ages of 3.9, 2.6, and 4.8Gyr respectively. These results are significantly younger than previous determinations (7.1, 5.0, and 8.3Gyr, respectively), based on integrated photometry or shallower CMDs. We rule out older ages for these clusters based on deep photometry and statistical isochrone fitting. We also estimate metallicities for the three clusters of [Fe/H]=-0.68, -0.57 and -0.90, respectively. These updated ages and metallicities are in good agreement with the age-metallicity relation for the bulk of SMC clusters. Total cluster masses ranging from ~7-11x10^3Mo were estimated from integrated flux, consistent with masses estimated for other SMC clusters of similar ages. These results reduce the number of SMC clusters known to be older than about 5 Gyr and highlight the need of deep and spatially resolved photometry to determine accurate ages for older, low-luminosity SMC star clusters.Comment: Accepted for publication as MNRAS letter, 5 pages, 5 figure
