It has built and characterised a laser and It has learned what each of the components does. It has been able to run the laser in single-mode and stabilised it around a desired setpoint thanks to a PID controller that It has programmed. It has established a communication between the PID controller programmed in LabVIEW and Arduino Due, the DAC that It has chosen after comparing it with another candidate. It has learned some basics of how the LightCrafter 4500 DMD works. The projected light is the composition of the lights of three LED’s, each of which has a certain on-time. The mirrors chose to be in on- or off-stages depending to the amount of intensity that we want for each colour.

The Community-based Coastal Resource Management Project in Orion, Bataan, Philippines was started in 1991. The village level fishers organizations have formed a municipal-wide association called the Samahan at Ugnayan ng Pangisdaan sa Orion (SUGPO). It represents 70% of the small-scale fishers in Orion and has taken on the task of rehabilitating the degraded fishing grounds. The experience in Orion indicates that coastal resource management can be successful if the fishers have ownership of the program and the costs and benefits of the program are distributed equally in a manner acceptable to them.
Telhados verdes para habitações de interesse social: retenção das águas pluviais e conforto térmico.

O crescimento populacional aliado à migração tem aumentado a pressão sobre o uso do solo urbano perpetuando sucessivos problemas de assentamentos informais e saneamento ambiental nos grandes centros. Esta situação se agrava ainda mais em épocas de chuvas intensas devido à ocorrência de enchentes. Este projeto faz parte de um conjunto de ações integradas de cidadania e inclusão social na região hidrográfica da baixada de Jacarepaguá, especificamente envolvendo a Comunidade da Vila Cascatinha, em Vargem Grande, a fim de gerar subsídios para políticas públicas em áreas de assentamentos informais, integrado ao projeto HIDROCIDADES (CNPq/CTHIDRO/CTAGRO), que visa a conservação da água em meios urbanos e periurbanos associado à cidadania, inclusão social e melhoria da qualidade de vida nas grandes cidades. Este projeto utilizou uma tecnologia adaptada dos telhados verdes para edificação popular (telhado de fibrocimento), com o objetivo de verificar aspectos construtivos, possíveis espécies com potencial de geração de renda, custos, efeitos no retardo do escoamento superficial das águas pluviais e outros benefícios associados a questões climáticas locais e de conforto do ambiente interno. Os resultados gerados demonstraram, entre outros, o estabelecimento de metodologia para implantação dos telhados verdes em habitações populares, o valor dos custos e resultados preliminares de espécies com potencial para geração de renda. Ainda, a implantação dos telhados verdes demonstrou ser promissora no controle do escoamento superficial, na aplicação do sistema de irrigação. Na simulação das chuvas, observou-se uma retenção de até 56% do volume precipitado. Observou-se o retardo da ocorrência do pico de até 8 minutos no telhado vegetado em relação ao telhado testemunho (convencional telhas fibrocimento). Foi observada a eficiência tanto no comportamento térmico interno como também no externo, uma redução da amplitude térmica interna em dia característico de verão (35,9 C), sendo capaz de r eduzir a temperatura interna em cerca de 2,0 C nos períodos mais quentes do dia e cerca de 4,0 C no ambiente externo em comparação com o telhado-testemunha (sem plantio), com potencial de modificação do microclima local.

Fish processing and quality control in Malawi are still poorly developed. Traditional fish processing methods are widely employed resulting in considerable post-harvest losses. One of the major challenges to steady and sustainable development in fish processing and quality management is the lack of adequately trained personel. This is directly reflected in poor institutional capacity. This project analyses the situation in fish processing and quality management in Malawi to identify gaps that require improvement. Specifically, the project assesses the role of training institutions in Malawi in capacity building for fish processing and quality management. The institution under discussion in this project is the Aquaculture and Fisheries Science Department at Bunda College of Agriculture, Malawi which is responsible for training students in aquaculture and fisheries science at the undergraduate level.Improvement in the teaching of fish processing and quality management in the Department of Aquaculture and Fisheries Science was identified as the major gap requiring action. The current teaching syllabus was thus analysed to identify weak areas. In conclusion, the project developed (as the major output) a teaching handbook for the Department of Aquaculture and Fisheries Science.

There is compelling evidence that increased gender equity can make a significant contribution towards alleviating poverty and increasing food security. But past efforts to integrate gender into agricultural research and development practice have failed to address the inequalities that limit women’s access to agricultural inputs, markets, resources and advice. A Gender Transformative Approach (GTA) goes beyond just considering the symptoms of gender inequality, and addresses the social norms, attitudes, behaviors and social systems that underlie them. The CGIAR Research Program on Aquatic Agricultural Systems (AAS) has placed the GTA at the heart of its gender strategy. This workshop was an opportunity for researchers, practitioners and donors working in this area to address the challenge of how to translate this approach into actual research and development practice. The workshop recommended that a GTA should be adopted alongside, not instead of, existing efforts to reverse gender disparities in resources, technologies and markets. It is through this pairing that improved social and material outcomes can be achieved, with the expectation that when achieved together, both types of outcomes will be more lasting than if achieved individually.
