Collecting Dust in the Upper Stratosphere at high latitudes: Constraints on the Compositions of Cosmic Dust Particles
The <i>Castalia</i> mission to Main Belt Comet 133P/Elst-Pizarro
We describe Castalia, a proposed mission to rendezvous with a Main Belt Comet (MBC), 133P/Elst-Pizarro. MBCs are a recently discovered population of apparently icy bodies within the main asteroid belt between Mars and Jupiter, which may represent the remnants of the population which supplied the early Earth with water. Castalia will perform the first exploration of this population by characterising 133P in detail, solving the puzzle of the MBC’s activity, and making the first in situ measurements of water in the asteroid belt. In many ways a successor to ESA’s highly successful Rosetta mission, Castalia will allow direct comparison between very different classes of comet, including measuring critical isotope ratios, plasma and dust properties. It will also feature the first radar system to visit a minor body, mapping the ice in the interior. Castalia was proposed, in slightly different versions, to the ESA M4 and M5 calls within the Cosmic Vision programme. We describe the science motivation for the mission, the measurements required to achieve the scientific goals, and the proposed instrument payload and spacecraft to achieve these
BRS 400 e BRS 401: novas cultivares de mandioca de mesa com raízes de polpa rosada.
A mandioca, além de ser uma excelente fonte de carboidratos para a alimentação humana, pode se tornar uma fonte de licopeno nas raízes de coloração rosada (Carvalho et al., 2011). O licopeno é um antioxidante, que apresenta ação no combate ao envelhecimento precoce e na prevenção do câncer de próstata (Shami; Moreira, 2004). Nesse contexto, a possibilidade de se disponibilizar raízes de mandioca com licopeno é uma das formas de melhorar a nutrição da população e de agregar valor às cultivares destinadas ao consumo humano. O programa de melhoramento genético de mandioca da Embrapa Cerrados está focado no desenvolvimento de cultivares específicas para uso culinário (cozida, frita, chips, mandioca palito, pré-cozida, massas, entre outras). As cultivares devem apresentar baixa capacidade de gerarem ácido cianídrico (HCN), ou seja, apresentarem teores do glicosídio linamarina inferiores a 100 mg para cada quilograma nas raízes de reserva frescas, produtividades elevadas de raízes com boas qualidades sensoriais e culinárias e também com maior tolerância/resistência a pragas e a doenças. Tudo isso aliado à aceitação por parte dos produtores e consumidores de mandioca. Com o objetivo de ofertar cultivares de mandioca de mesa com coloração da polpa das raízes rosadas adaptadas às condições do Distrito Federal, a Embrapa disponibiliza as cultivares BRS 400 e BRS 401 aos produtores da região.bitstream/item/221840/1/ComTec-185-Eduardo-Alano-web.pd
BRS 396, BRS 397, BRS 398 e BRS 399: novas cultivares de mandioca de mesa com coloração da polpa das raízes amarela e creme.
Os consumidores de mandioca de mesa (cozidas, fritas, chips, mandioca palito, pré-cozida, massas, entre outras) estão se tornando cada vez mais exigentes quanto aos aspectos organolépticos, sanitários e nutricionais. Essa mudança no perfil forçou os produtores a uma rápida incorporação de tecnologias modernas de cultivo. Nesse sentido, o programa de melhoramento genético de mandioca da Embrapa Cerrados foca no desenvolvimento de cultivares de mandioca de mesa com baixos teores de HCN nas raízes, mais nutritivas, precoces, produtivas, adaptadas ao plantio mecanizado e ao cultivo irrigado, resistentes às principais pragas e doenças e com boas qualidades culinárias. Tudo isso aliado à boa aceitação por parte dos produtores e consumidores de mandioca.bitstream/item/221841/1/ComTec-186-Eduardo-Alano-Web.pd
Second chances: Investigating athletes’ experiences of talent transfer
Talent transfer initiatives seek to transfer talented, mature individuals from one sport to another. Unfortunately talent transfer initiatives seem to lack an evidence-based direction and a rigorous exploration of the mechanisms underpinning the approach. The purpose of this exploratory study was to identify the factors which successfully transferring athletes cite as facilitative of talent transfer. In contrast to the anthropometric and performance variables that underpin current talent transfer initiatives, participants identified a range of psychobehavioral and environmental factors as key to successful transfer. We argue that further research into the mechanisms of talent transfer is needed in order to provide a strong evidence base for the methodologies employed in these initiatives
Health and economic benefits of achieving contraceptive and maternal health targets in small island developing states in the Pacific and Caribbean
INTRODUCTION: Reducing unmet need for modern contraception and expanding access to quality maternal health (MH) services are priorities for improving women's health and economic empowerment. To support investment decisions, we estimated the additional cost and expected health and economic benefits of achieving the United Nations targets of zero unmet need for modern contraceptive choices and 95% coverage of MH services by 2030 in select Small Island Developing States. METHODS: Five Pacific (Kiribati, Samoa, Solomon Islands, Tonga and Vanuatu) and four Caribbean (Barbados, Guyana, Jamaica and Saint Lucia) countries were considered based on population survey data availability. For each country, the Lives Saved Tool was used to model costs, health outcomes and economic benefits for two scenarios: business-as-usual (BAU) (coverage maintained) and coverage-targets-achieved, which scaled linearly from 2022 (following COVID-19 disruptions) coverage of evidence-based family planning and MH interventions to reach United Nations targets, including modern contraceptive methods and access to complete antenatal, delivery and emergency care. Unintended pregnancies, maternal deaths, stillbirths and newborn deaths averted by the coverage-targets-achieved scenario were converted to workforce, education and social economic benefits; and benefit-cost ratios were calculated. RESULTS: The coverage-targets-achieved scenario required an additional US10.8M-US82.4M to maintain BAU). This additional investment was estimated to avert 126 000 (40%) unintended pregnancies, 2200 (28%) stillbirths and 121 (29%) maternal deaths and lead to a 15-fold economic benefit of US67.0M-US17.8M (US22.4M) was needed to reach the targets (4% more than US426.2M (US745.7M) by 2050. CONCLUSION: Achieving full coverage of contraceptive and MH services in the Pacific and Caribbean is likely to have a high return on investment
