European cropping systems are often characterized by short rotations or even monocropping,leading to environmental issues such as soil degradation,water eutrophication,and air pollution including greenhouse gas emissions,that contribute to climate change and biodiversity *** use of diversification practices(i.e.,intercropping,multiple cropping including cover cropping and rotation extension),may help enhance agrobiodiversity and deliver ecosystem services while developing new value *** its benefits,crop diversification is hindered by various technical,organizational,and institutional barriers along value chains(input industries,farms,trading and processing industries,retailers,and consumers)and within sociotechnical systems(policy,research,education,regulation and advisory).Six EU-funded research projects have joined forces to boost crop diversification by creating the European Crop diversification Cluster(CdC).This Cluster aggregates research,innovation,commercial and citizen-focused partnerships to identify and remove barriers across the agrifood system and thus enables the uptake of diversification measures by all European value-chain *** CdC will produce a typology of barriers,develop tools to accompany actors in their transition,harmonize the use of multicriteria assessment indicators,prepare policy recommendations and pave the way for a long-term network on crop diversification.

Escherichia coil Removal in Tropical Oligotrophic and Eutrophic Lakes

Journal of Environmental Science and Engineering(A) 2013年第12期2卷 719-724页

The mechanisms by which oligotrophic and eutrophic lakes rid itself of Escherichia coli or faecal coliforms are still not clearly understood. This study sought to review the various means by which E. coli or faecal coliforms are inactivated or removed in lakes. The review cited temperature, solar radiation, predation, starvation, attachment and sedimentation as key factors that aid the removal of E. coli in lakes. In eutrophic lakes additional factors such as the role of algal biomass may play a role due to increased pH and dissolved oxygen levels attributed to algal presence. Algal toxins or exudates may also play a role although this is still under debate. The interactive effect of two or more of these factors on E. coli inactivation and the relative importance of these mechanisms on E. coli removal are still not known. Areas for further research include the role of algae in sedimenting E. coli or faecal coliforms and the possible role of algal exudates on E. coli inactivation.

Analysis of deformation in Ni-Cr Structures with New and Recast Alloys

引用

Materials Sciences and Applications 2015年第7期6卷 707-712页

作者： Humberto Gennari Filho Marcelo Coelho Goiato José Vitor Quinelli Mazaro Karina helga Leal Túrcio State Paulista University S&atilde o Paulo Brazil

The present study analyzed new and recast Ni-Cr alloys, regarding the relationship between the applied force and the deformation in cantilevered bar segments, with dimensions of 4.0 mm, 3.5 mm, 3.0 mm in thickness, 4.5 mm width and 15 mm length, on a universal testing machine “EMIC”. The bars in the tests were initially obtained acrylic resin by 4.8 mm wide × 4.3 mm thick × 4 cm long. We obtained 30 bars divided into two groups, with 15 to test new alloys and 15 with alloys recast. The alloy used was Tilite. For the application of the load, the bars were attached to “EMIC” where the active tip of 200 kgf load cell was at a specific point of the bar (15 mm) with a speed of 0.5 mm per minute. The data showed statistically significant differences in relation to alloys and thickness among the bars, and all thicknesses evaluated were different. Thus, it was concluded that there was statistically significant difference between the groups and their variables, and that the alloys recast could be reused at least 1 time, without loss of properties.
