    An easy mixed-method analysis tool to support rural development strategy decision-making for beekeeping

    The EU has long-recognised the functions and contributions of beekeeping in sustainable rural area development. In 2018, the EU adopted the Pollinator Initiative to strengthen its pollinator conservation policies. To support the design of effective rural development actions, this work describes and tests an easy-to-apply, mixed-method tool for use with SWOT analysis. A two-step methodology was trialled with beekeepers in Piedmont Region (NW Italy). In step one, two independent groups of beekeepers operating in separate protected and intensive agricultural areas completed a SWOT matrix. In step two, three expert panels (beekeeper association leaders, honey market organisation leaders, and entomologists) prioritised the effects of the SWOT items with a quantitative weighting and rating process. Results suggest that the sector needs better-targeted incentives and that ‘soft’ policies on extension, advisory, and institutional measures could play a relevant role. The method was also confirmed as suitable for use with non-expert evaluators, such as policy officers and practitioners

    PMMA-based bone cements and the problem of joint arthroplasty infections: Status and new perspectives

    Get PDF
    Polymethyl methacrylate (PMMA)-based bone cement is a biomaterial that has been used over the last 50 years to stabilize hip and knee implants or as a bone filler. Although PMMA-based bone cement is widely used and allows a fast-primary fixation to the bone, it does not guarantee a mechanically and biologically stable interface with bone, and most of all it is prone to bacteria adhesion and infection development. In the 1970s, antibiotic-loaded bone cements were introduced to reduce the infection rate in arthroplasty; however, the eciency of antibiotic-containing bone cement is still a debated issue. For these reasons, in recent years, the scientific community has investigated new approaches to impart antibacterial properties to PMMA bone cement. The aim of this review is to summarize the current status regarding antibiotic-loaded PMMA-based bone cements, fill the gap regarding the lack of data on antibacterial bone cement, and explore the progress of antibacterial bone cement formulations, focusing attention on the new perspectives. In particular, this review highlights the innovative study of composite bone cements containing inorganic antibacterial and bioactive phases, which are a fascinating alternative that can impart both osteointegration and antibacterial properties to PMMA-based bone cement

    Validação de método multirresíduo para determinação de pesticidas em alimentos empregando QuEChERs e UPLC-MS/MS.

    This paper presents a practical and rapid method which was validated for simultaneous quantification and confirmation of 29 pesticides in fruits and vegetables using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The samples were extracted following the method known as QuEChERS. Using the developed chromatographic conditions, the pesticides can be separated in less than 9 min. Two multiple reaction monitoring (MRM) assays were used for each pesticide. Four representative matrices (lettuce, tomato, apple and grapes) were selected to investigate the effect in recoveries and precision. Typical recoveries ranged from 70-120%, with relative standard deviation (RSDs) lower than 20%

    Manual do usuário do programa AGROSCRE: apoio à avaliação de tendências de transporte de princípios ativos de agrotóxicos.

    O programa AGROSCRE foi elaborado para conferir agilidade da avaliação de modelos matemáticos screening, que auxiliam a análise do potencial de contaminação de agrotóxicos em água. Este trabalho apresenta o manual do usuário deste programa, possibilitando uma maior divulgação do uso dos modelos ?screening? e fomentando avaliações, cada vez mais fidedignas, da realidade local do ambiente de produção agrícola nacional, na medida em que os dados de entrada forem refinados. Foi desenvolvido em linguagem Quick Basic 4.5 e necessita de 11K de memória para ser utilizado em modo executável.bitstream/item/204159/1/Manual-Agroscre-Pessoa-2007.pdf; bitstream/item/103181/1/Doc-61-Agroscre.zipEndereço para baixar o programa AGROSCRE: http://www.cnpma.embrapa.br/forms/agroscre.php
