O avanço da incidência da doença no cafeeiro pode ser contido com uso de fungicidas. Suas aplicações podem ser associadas à intensidade da ferrugem. O Sistema de Alerta da Ferrugem do Cafeeiro (SAFCAFE) é uma ferramenta que auxilia os técnicos da Fundação Procafé na confecção de boletins mensais com sugestões fitossanitárias para o público-alvo (THAMADA et al., 2013)

Tribological behavior of shape-specific microplate-enriched synovial fluids on a linear two-axis tribometer

Nano- and micro-particles are being increasingly used to tune interfacial frictional properties in diverse applications, from friction modifiers in industrial lubrication to enhanced biological fluids in human osteoarthritic joints. Here, we assessed the tribological properties of a simulated synovial fluid enriched with non-spherical, poly lactic-co-glycolic acid (PLGA) microparticles (μPL) that have been previously demonstrated for the pharmacological management of osteoarthritis (OA). Three different μPL configurations were fabricated presenting a 20 μm 20 μm square base and a thickness of 5 μm (thin, 5H μPL), 10 μm (10H μPL), and 20 μm (cubical, 20H μPL). After extensive morphological and physicochemical characterizations, the apparent Young’s modulus of the μPL was quantified under compressive loading returning an average value of 6 kPa, independently of the particle morphology. Then, using a linear two-axis tribometer, the static (μs) and dynamic (μd) friction coefficients of the μPL-enriched simulated synovial fluid were determined in terms of particle configuration and concentration, varying from 0 (fluid only) to 6105 μPL/mL. The particle morphology had a modest influence on friction, possibly because the μPL were fully squeezed between two mating surfaces by a 5.8 N normal load realizing boundary-like lubrication conditions. Differently, friction was observed to depend on the dimensionless parameter , defined as the ratio between the total volume of the μPL enriching the simulated synovial fluid and the volume of the fluid itself. Both coefficients of friction were documented to grow with reaching a plateau of μs 0.4 and μd 0.15, already at  210-3. Future investigations will have to systematically analyze the effect of sliding velocity, normal load, and rigidity of the mating surfaces to elucidate in full the tribological behavior of μPL in the context of osteoarthritis

Le scommesse sportive in Italia: volume, densità e competitività

AbstractThe attitude of Italians towards games of chance increased dramatically in the last fifteen years thanks particularly to the introduction of new legal gambling and lotteries, run by the State, characterized by the simplicity and immediacy of the win. Among them, scratch and wins have become one of the most popular phenomenon in the Italian gambling realm and have increased the tendency towards risk of many consumers; the purchase of scratch cards has, nowadays, become almost complementary to people's weekly expenditure. This paper focuses on the tendency of the Italian citizens towards gambling, utilizing it as a tool for fighting tax evasion. In particular, evasion associated with the reduction of taxable income due to the omission of tax receipts on behalf of traders, craftsmen and self-employers. The idea is to replace fiscal receipts with scratch cards giving citizens the chance to participate in the local or national lotteries. Based on the successful experience in China - fighting tax evasion through lotteries - our paper discusses the possibility of putting an end to this sort of «mutual convenience » found on behalf of the abovementioned categories and customers; for the first time in the Italian tax system, instead of issuing fiscal receipts we would introduce elements of «potential conflict» between them able to increase the level of tax compliance.
