Necessidades hídricas do feijoeiro irrigado no noroeste paulista /Farinassi, Larissa Godarelli January 2018 (has links)
Orientador: Fernando Braz Tangerino Hernandez / Resumo: O feijão comum (Phaseolus vulgaris L.) de grande importância sócio-econômica para o Brasil, sendo o segundo maior produtor e principal consumidor mundial. O objetivo neste trabalho foi compreender as metodologias disponíveis para manejo e avaliação do uso da água em culturas irrigadas e estimar a evapotranspiração atual (ETa) e ainda determinar coeficientes de cultura nas áreas cultivadas com feijão de inverno utilizando as técnicas baseadas em sensoriamento remoto (algoritmo SAFER - Simple Algorithm for Retrieving Evapotranspiration), confrontando-os com as estimativas da evapotranspiração da cultura (ETc) preconizados pelo Boletim FAO 56. O estudo foi realizado em condições irrigadas por pivô central com sete épocas de semeadura de feijão de inverno nos municípios de Rubinéia e Pereira Barreto. Cada época de semeadura recebeu um manejo de irrigação, realizado pelo próprio irrigante e uma simulação sugerida de irrigação mantendo os mesmos dados de ETo e chuva. As imagens do satélite LandSat 8 foram utilizas para execução do algoritmo SAFER para a obtenção da relação entre a evapotranspiração atual e a evapotranspiração de referência. Foram feitas a análise da produtividade de água em função da produção obtida para cada época de semeadura. Para as semeaduras de feijão de outono/inverno em Rubinéia, o irrigante possui a opção de utilizar dados das Estações Ilha Solteira e Marinópolis, fato que as ETo são semelhantes.

The objective of this work was to understand the available methodologies for the management and evaluation of water use in irrigated crops and to estimate current evapotranspiration (ETa) and to determine crop coefficients in areas cultivated with winter bean using techniques based on remote sensing SAFER - Simple Algorithm for Retrieving Evapotranspiration), comparing them with estimates of crop evapotranspiration (ETc) recommended by FAO Bulletin 56. The study was conducted under central pivot irrigation conditions with seven winter bean sowing seasons in the municipalities of Rubinéia and Pereira Barreto. Each sowing season received an irrigation management, performed by the irrigator and a suggested irrigation simulation, maintaining the same ETo and rainfall data. The images of the LandSat 8 satellite were used to execute the SAFER algorithm to obtain the relation between the current evapotranspiration and the reference evapotranspiration. The water productivity was analyzed according to the production obtained for each sowing season. For the autumn / winter bean sowing in Rubinéia, the irrigant has the option to use data from the Ilha Solteira and Marinópolis Stations, a fact that ETo are similar. Results obtained from the irrigations used by the irrigator overestimated the water storage in the soil, so it was necessary to carr... (Complete abstract click electronic access below) / Mestre

Previous issue date: 2018-04-06 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / O questionamento sobre o uso da água na agricultura torna-se cada vez mais constante, diante do contexto das mudanças climáticas e da necessidade de aumentar a produção de biomassa para alimentação, transformação ou processamento. O Perímetro Irrigado Pontal Sul, localizado na bacia hidrográfica do Rio Pontal, na região semiárida do estado de Pernambuco, está em início de operação. Assim, a avaliação do fluxo de água entre a superfície terrestre e a atmosfera e da produtividade da água podem contribuir para a gestão hídrica em escala regional. Para isso, imagens MODIS (Terra) e dados de estações agrometeorológicas no período entre 2000 a 2015 foram utilizadas conjuntamente com o Simple Algorithm for Evapotranspiration Retrieving (SAFER) para a estimativa da evapotranspiração real (ETr), da biomassa (BIO) e da produtividade da água (WP) no Perímetro Irrigado Pontal Sul. A ETr apresentou valor médio de 0,91 mm dia-1 na área com vegetação natural - Caatinga (VN), e de 1,50 mm dia-1 na área com agricultura irrigada (AI) durante os 16 anos de avaliação. A BIO média para o mesmo período foi de 30,50 kg ha-1 dia-1na VN e 49,32 kg ha-1 dia-1 na AI. A WP apresentou valor médio de 2,06 kg m-3 na VN e 2,43 kg m-3 na AI. Os menores valores médios de ETr, BIO e WP foram registrados em 2013 (0,40 mm dia-1, 9,95 kg ha-1 dia-1 e 1,53 kg m-3, respectivamente), enquanto os maiores valores médios observados em 2009 (1,81 mm dia-1, 66,48 kg ha-1 dia-1 e 2,79 kg m-3 respectivamente). A área de AI condiciona um incremento às médias diárias dos parâmetros estudados. A VN apresentou resultados relevantes nas regiões em que a Caatinga é mais densa. As estimativas da ETr, BIO e WP permitem compreender de maneira mais ampla a demanda hídrica em escala regional no decorrer do período avaliado, relacionando seus resultadas aos efeitos causados pelo uso e ocupação da terra e as possíveis mudanças climáticas da região.

A model to integrate the management of hazards and disasters in the national sustainable development planning of the MaldivesJameel, Ahmed January 2007 (has links)
The small land area of the islands of the Maldives, combined with high population density, makes the communities of these islands vulnerable to natural disaster events such as flooding and tsunami. The Indian Ocean Tsunami on 26 December 2004 impacted 69 islands of the Maldives, killing 82 people, leaving 26 people missing and 15, 000 people internally displaced, making it the worst disaster in recorded history. Following the event, the Government of the Maldives announced a Safer Island Development Programme which seeks to provide the infrastructure necessary to adapt to natural disasters. The key focus of disaster management is to reduce the vulnerability of the communities exposed to hazards and risks, and to help them to enhance their resilience. Efforts have been made to develop safer and sustainable communities in all corners of the developed and developing worlds. New Zealand Government announced its effort to build safe and secure communities in 2007 while at a local level the Christchurch City Council published the Safer Christchurch Strategy in 2005. Overseas, the Community Strategy 2000, outlines the vision of "A safe and strong Island" at Isle of Wight United Kingdom. The islands of the Maldives have natural characteristics which make them vulnerable to disasters such as tsunami. This research has been able to identify the relationship between these characteristics and the natural vulnerability of the islands using the data that was collected following the Indian Ocean Tsunami. Out of 11 island, that have been identified for the Safer Islands Development Programme, one island is found to have very high natural vulnerability and 5 islands a high natural vulnerability, from the island vulnerability index model developed through this study. The Island Vulnerability Index model could be used to enhance the present Safer Island Development Programme island selection criteria, to reduce the possibility of 'building risk' into the infrastructure development on the islands. The index could also be used in the Environmental Impact Assessment studies to address the issue of disasters, effective resources allocation in the Public Sector Infrastructure Programme for 'building back better', and resource identification in land use planning.

The Danger of Field Welding : Esab ExoRosenlind, Rebecka January 2016 (has links)
Welding is today seen as one of the most dangerous professions on earth, mostly because of the toxic fumes. These fumes can lead to a variety of diseases and in worst case death. Now imagine this problem when you are working at different places every day and you can not always bring the equipment needed to protect your health since they are either too big or does not have enough capacity. This is a problem which welders that work at temporary workplaces have to face every day. With this project I have looked into this problem and come up with a product that makes the temporary workplaces safer and at the same time keeps an efficient workflow.

Integrating Chemical Hazard Assessment into the Design of Inherently Safer ProcessesLu, Yuan 2011 December 1900 (has links)
Reactive hazard associated with chemicals is a major safety issue in process industries. This kind of hazard has caused the occurrence of many accidents, leading to fatalities, injuries, property damage and environment pollution. Reactive hazards can be eliminated or minimized by applying Inherently Safer Design (ISD) principles such as "substitute" or "moderate" strategies. However, ISD would not be a feasible option for industry without an efficient methodology for chemical hazard assessment, which provides the technical basis for applying ISD during process design.
In this research, a systematic chemical hazard assessment methodology was developed for assisting the implementation of ISD in the design of inherently safer process. This methodology incorporates the selection of safer chemicals and determination of safer process conditions, which correspond to "substitute" and "moderate" strategies in ISD. The application of this methodology in conjunction with ISD technique can effectively save the time and investment spent on the process design.
As part of selecting safer chemicals, prediction models were developed for predicting hazardous properties of reactive chemicals. Also, a hazard index was adopted to rate chemicals according to reactive hazards. By combining the prediction models with the hazard index, this research can provide important information on how to select safer chemicals for the processes, which makes the process chemistry inherently safer.
As part of determining safer process conditions, the incompatibility of Methyl Ethyl Ketone Peroxide (MEKPO) with iron oxide was investigated. It was found that iron oxide at low levels has no impact on the reactive hazards of MEKPO as well as the operational safety. However, when iron oxide is beyond 0.3 wt%, it starts to change the kinetics of MEKPO runaway reaction and even the reaction mechanism. As a result, with the presence of a certain level of iron oxide (> 0.3 wt%), iron oxide can intensify the reactive hazards of MEKPO and impose higher risk to process operations. The investigation results can help to determine appropriate materials for fabricating process equipment and safer process conditions.

Evolução da expansão da agricultura irrigada por pivô central e da evapotranspiração incremental no Noroeste Paulista /Oliveira, Daniela Araujo de January 2020 (has links)
Orientador: Marcelo Andreotti / Resumo: A irrigação vem sendo desenvolvida há séculos pela humanidade e atualmente mais da metade da produção de alimentos provém de áreas irrigadas. Além da garantia de produtividade das culturas, a irrigação traz desenvolvimento socioeconômico para a região onde é instalada, sendo assim é necessário o aumento das áreas irrigadas aliado à boa gestão dos recursos hídricos para a garantia dos usos múltiplos da água. A estimativa da evapotranspiração de determinada região contribui para um melhor conhecimento do ciclo hidrológico e uma melhor capacidade de quantificar mudanças futuras na gestão dos recursos hídricos. Este trabalho objetivou-se em apresentar a evolução das áreas irrigadas por pivô central na região Noroeste Paulista entre 2000 e 2018 e ainda, estimar a evapotranspiração atual em larga escala na região, comparando os anos 2010, 2017 e 2018, utilizando técnicas de sensoriamento remoto. Observou-se a implantação de 241 equipamentos tipo pivô central irrigando 10.473 hectares do ano 2000 a 2018, acumulando uma área irrigada de 17.135 hectares com 320 sistemas. A evapotranspiração atual se diferiu no espaço e no tempo na região, tendo valores que variaram entre 0,5 e 2,5 mm dia-1, sendo as maiores taxas registradas nas áreas irrigadas e as maiores médias foram obtidas no período de chuvas da região em todos os anos estudados, tendo uma evapotranspiração incremental de 0,2 mm dia-1 entre 2010 e 2018. / Abstract: Irrigation is being developed for centuries by man kind and currently more than half of food production come from irrigated areas. Besides the guaranty of crop productivity, irrigation brings social-economic development for the regions where it is being installed, thus it’s necessary the expansion of irrigated areas associated to a good management of hydric resources for the guaranty of multiple uses of water. The evapotranspiration estimation of a certain region contributes to a better knowledge of the hydrological cycle and a better capacity to quantify future changes in the management of hydric resources. This work aimed in showing the evolution of irrigated areas by central pivot in the Paulista Northwest region between 2000 and 2018 and yet, estimate the current evapotranspiration in large scale in the region, comparing it to the years 2010, 2017 and 2018, using remote censoring techniques. It was observed the implementation of 241 equipments of central pivot kind irrigating 10,473 hectares from 2000 to 2018, accumulating an irrigated area of 17,135 hectares with 320 systems. The current evapotranspiration differed in space and in time in the region, showing values that vary from 0.5 and 2.5 mm day-1 , being the highest rates recorded in the irrigated areas and the higher rates were obtained in the rainy season of the region in all studied years, having an incremental evapotranspiration of 0.2 mm day-1 between 2010 and 2018. / Mestre

Fidelity and the impact of patient safety huddles on teamwork and safety culture: an evaluation of the Huddle Up for Safer Healthcare (HUSH) project.Lamming, Laura, Montague, Jane, Crosswaite, Kate, Faisal, Muhammad, McDonach, E., Mohammed, A. Mohammed, Cracknell, A., Lovatt, A., Slater, B. 05 October 2021 (has links)
Yes / The Patient Safety Huddle (PSH) is a brief multidisciplinary daily meeting held to discuss threats to patient safety and actions to mitigate risk. Despite growing interest and application of huddles as a mechanism for improving safety, evidence of their impact remains limited. There is also variation in how huddles are conceived and implemented with insufficient focus on their fidelity (the extent to which delivered as planned) and potential ways in which they might influence outcomes. The Huddle Up for Safer Healthcare (HUSH) project attempted to scale up the implementation of patient safety huddles (PSHs) in five hospitals - 92 wards - across three UK NHS Trusts. This paper aims to assess their fidelity, time to embed, and impact on teamwork and safety culture.
A multi-method Developmental Evaluation was conducted. The Stages of Implementation Checklist (SIC) was used to determine time taken to embed PSHs. Observations were used to check embedded status and fidelity of PSH. A Teamwork and Safety Climate survey (TSC) was administered at two time-points: pre- and post-embedding. Changes in TSC scores were calculated for Trusts, job role and clinical speciality.
Observations confirmed PSHs were embedded in 64 wards. Mean fidelity score was 4.9/9. PSHs frequently demonstrated a 'fear free' space while Statistical Process Control charts and historical harms were routinely omitted. Analysis showed a positive change for the majority (26/27) of TSC questions and the overall safety grade of the ward.
PSHs are feasible and effective for improving teamwork and safety culture, especially for nurses. PSH fidelity criteria may need adjusting to include factors deemed most useful by frontline staff. Future work should examine inter-disciplinary and role-based differences in TSC outcomes. / The Health Foundation’s Scaling Up Improvement Programme: Round One (2015)
