Pensar a arte na modernidade Ă© considerar que, desde os finais do sĂ©culo XIX, nada mais foi estĂĄvel e que os cruzamen-tos, interaçÔes e combinaçÔes entre as linguagens (artĂsticas ou nĂŁo) se tornaram cada vez mais complexos e inevitĂĄveis. Por is-so, tendo por foco os finais do sĂ©culo XIX e o inĂcio do sĂ©culo XX, este nĂșmero da Revista Cerrados se dedicou a refletir e a discutir sobre produçÔes artĂsticas que, ao longo dessa virada de sĂ©culos, reivindicaram e comunicaram, no Brasil e no mundo, os espaços de diĂĄlogos, fronteiras e interferĂȘncias entre as artes
Experimental study of a CoCrMo alloy treated by SMAT under rotating bending fatigue
The main objective of this work is to understand the fundamental damage mechanisms involved in a SMAT treated CoCrMo alloy
subjected to fatigue under rotating bending loads. For this purpose, different load amplitudes in rotating bending are imposed on
cylindrical specimens, in as-machined and SMAT states. Different material characterizations are performed in order to determine
which features play an important role in fatigue life of the studied alloy. Such characterizations are done via digital microscopy,
electron backscatter diffraction (EBSD), roughness measurements and microhardness tests. The fatigue results presented in the
form of S-N diagram show that SMAT with a moderate intensity (SMAT-2) can enhance the fatigue performance of the CoCrMo
alloy, whereas SMAT with a higher intensity (SMAT-3) seems to deteriorate it. This fatigue life decrease is probably due to surface
micro-cracks generated by an over-peening phenomenon
Formulation dâun Programme National du Secteur Rural robuste au Burkina Faso : Quelles thĂ©matiques nouvelles issues du processus des scĂ©narios socio- Ă©conomiques et climatiques?
Dans le cadre du partenariat initié en 2015 entre le
Programme de recherche du CGIAR sur le Changement
Climatique, lâAgriculture et la SĂ©curitĂ© Alimentaire
(CCAFS) et le Secrétariat Permanent de la Coordination
des Politiques Sectorielles Agricoles (SP-CPSA), en
collaboration avec dâautres programmes et centres de
recherche du CGIAR, une analyse du Programme
National du Secteur Rural (PNSR) fondée sur les
scénarios socio-économiques et climatiques du CCAFS a
pu ĂȘtre menĂ©e avec la participation effective des parties
prenantes du secteur rural du Burkina Faso. Les 22
recommandations qui en sont issues devraient permettre
une prise en compte effective des facteurs socio-
Ă©conomiques, environnementaux et climatiques
plausibles dans le futur proche et lointain, et ainsi aider Ă
rendre le PNSR II plus robuste face aux incertitudes
futures liées au changement climatique, aux dynamiques
mondiales, aux évolutions socioéconomiques, aux
changements des normes et valeurs, etc. En outre, un
exercice avec lâensemble des acteurs impliquĂ©s a
consisté à traduire lesdites recommandations en actions
et thématiques nouvelles à prendre en compte lors de la
formulation du PNSR II. Les Ă©changes entre acteurs ont
Ă©galement fait ressortir la nĂ©cessitĂ© dâune implication
transversale de la recherche dans la mise en Ćuvre des
activitĂ©s de cet important outil politique quâest le PNSR I
Formulation of a Robust National Rural Sector Program in Burkina Faso: What new themes have emerged from the socio-economic and climate scenarios process?
Under the partnership initiated in 2015 between the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) and the Permanent Secretariat for Coordination of Agricultural Sector Policies (SP-CPSA), in collaboration with other CGIAR research programs and centers, an analysis of the National Rural Sector Program (PNSR) based on the CCAFS socio-economic and climate scenarios was conducted with the effective participation of rural sector stakeholders in Burkina Faso. Twenty-two (22) recommendations were made to allow for the effective mainstreaming of plausible socio-economic, environmental and climatic factors in the near and distant future, that will make PNSR II more robust to face future uncertainties related to climate change, global dynamics, socio-economic changes, changes in norms and values, etc. In addition, an exercise with all the stakeholders helped in translating the said recommendations into new actions and themes to be taken into account when formulating PNSR II. Discussions between the stakeholders also underscored the need for crosscutting involvement of research in the implementation of the activities of PNSR II
Examining the generalizability of research findings from archival data
This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizabilityâfor the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples
The European Reference Genome Atlas: piloting a decentralised approach to equitable biodiversity genomics.
ABSTRACT: A global genome database of all of Earthâs species diversity could be a treasure trove of scientific discoveries. However, regardless of the major advances in genome sequencing technologies, only a tiny fraction of species have genomic information available. To contribute to a more complete planetary genomic database, scientists and institutions across the world have united under the Earth BioGenome Project (EBP), which plans to sequence and assemble high-quality reference genomes for all âŒ1.5 million recognized eukaryotic species through a stepwise phased approach. As the initiative transitions into Phase II, where 150,000 species are to be sequenced in just four years, worldwide participation in the project will be fundamental to success. As the European node of the EBP, the European Reference Genome Atlas (ERGA) seeks to implement a new decentralised, accessible, equitable and inclusive model for producing high-quality reference genomes, which will inform EBP as it scales. To embark on this mission, ERGA launched a Pilot Project to establish a network across Europe to develop and test the first infrastructure of its kind for the coordinated and distributed reference genome production on 98 European eukaryotic species from sample providers across 33 European countries. Here we outline the process and challenges faced during the development of a pilot infrastructure for the production of reference genome resources, and explore the effectiveness of this approach in terms of high-quality reference genome production, considering also equity and inclusion. The outcomes and lessons learned during this pilot provide a solid foundation for ERGA while offering key learnings to other transnational and national genomic resource projects.info:eu-repo/semantics/publishedVersio
