Nitrogen removal and sustainability of vertical flow constructed wetlands for small scale wastewater treatment

The challenge for wastewater professionals is to design and operate treatment processes that support human well being and are environmentally sensitive throughout the life-cycle. This research focuses on one technology for small-scale wastewater treatment: the vertical flow constructed wetland (VFCW), which is herein investigated for the capacity to remove ammonium and nitrate nitrogen from wastewater. Hydraulic regime and presence/absence of vegetation are the basis for a three-phase bench scale experiment to determine oxygen transfer and nitrogen fate in VFCWs. Results show that 90% NH4+-N removal is achieved in aerobic downflow columns, 60% NO3--N removal occurs in anaerobic upflow columns, and 60% removal of total nitrogen can be achieved in downflow-upflow in-series. The experimental results are studied further using a variably saturated flow and reactive transport model, which allows a mechanistic explanation of the fate and transport of oxygen and nitrogen. The model clarifies the mechanisms of oxygen transport and nitrogen consumption, and clarifies the need for readily biodegradable COD for denitrification. A VFCW is then compared to a horizontal flow constructed wetland (HFCW) for life cycle environmental impacts. High areal emissions of greenhouse gases from VFCWs compared to HFCWs are the driver for the study. The assessment shows that because a VFCW is only 25% of the volume of an HFCW designed for the same treatment quality, the VFCW has only 25-30% of HFCW impacts over 12 impact categories and 3 damage categories. Results show that impacts could be reduced by design improvements. Design recommendations are downflow wetlands for nitrification, upflow wetlands for denitrification, series wetlands for total nitrogen removal, hydraulic load of 142 L/m2d, 30 cm downflow wetland depth, 1.0 m upflow wetland depth, recycle, vegetation and medium-grained sand. These improvements will optimize nitrogen removal, minimize gaseous emissions, and reduce wetland material requirements, thus reducing environmental impact without sacrificing wastewater treatment quality.

Aceitação e eficácia de um programa de intervenção psicoeducativa para pais de crianças com asma: Estudo exploratório

Considerando a importância que a educação sobre a asma deve assumir no plano de gestão familiar da doença, e a falta de programas deste tipo em Portugal, construímos uma intervenção psicoeducativa breve para pais de crianças com asma entre os 7 e os 13 anos, visando a aquisição de atitudes mais positivas na gestão da doença. O estudo teve como objetivo avaliar a aceitação, eficácia e a satisfação relativa ao programa intervenção. Completaram a intervenção 10 mães, tendo participado nas 3 sessões de grupo e nos 3 momentos de avaliação (linha de base, final da intervenção e follow-up a 9 meses). Para além da recolha de informação sociodemográfica e clínica, aplicaram-se dois questionários, um de conhecimentos sobre a asma e outro de qualidade de vida da criança (DISABKIDS-37, versões pais e criança). Utilizou-se também uma entrevista sobre a gestão da asma pela família (FAMSS) na avaliação inicial e no follow-up. Os resultados evidenciaram uma melhoria moderada no conhecimento dos pais e nas práticas de gestão da asma, confirmando a utilidade de incluir a intervenção psicoeducativa nos cuidados às crianças com asma.

Gymnasielärares skrivpraktiker : Skrivande som professionell handling i en digitaliserad skola

The aim of this thesis is to contribute to deeper knowledge about the writing practices of teachers in upper secondary school. Schools are under constant pressure to respond to the needs and expectations of an ever-changing society and political intentions. A major factor in this change which is taking place in schools is digitalization. Another factor is the adoption of new governing principles for schools involving management by goals and results, which brings increased demands for written documentation of teachers' work. In order to describe and problematize this development the thesis is based on a combination of Critical Discourse Analysis and New Literacy (Clark and Ivanič, 1997). The theoretical framework rests upon an understanding of writing as social action and the idea that texts both affect and are affected by the social environment. The empirical study focuses on twelve teachers and their writing practices, analyzed during week-long field visits over three years. The teachers' talk about their writing is used together with analyses of texts and images to investigate parts of teachers' writing which, according to the teachers, are considered complex and problematic. The findings indicate significant differences between the writing practices of the individual teachers, where each teacher has his or her own system of texts fulfilling different purposes. Despite these differences it is still possible to identify recurrent themes in the discursive conditions for teachers' writing: efficiency, reuse, authority, audit, relationships to addressees, and room to maneuver. The study illustrates possible dilemmas for teachers' writing at the intersection of teachers' professional responsibility and demands for accountability.

El videojuego League of legends y su efecto en memoria de trabajo visual y solución de problemas

El propósito de este estudio es medir los efectos que tiene el videojuego League of Legends en los procesos cognitivos de memoria de trabajo visual (MVT) y solución de problemas (SP). Para medir dichos efectos se implementó un diseño pre test-post con un grupo experimental y uno control, compuestos cada uno por siete participantes, en donde se evaluaron los procesos previamente mencionados utilizando los cubos de Corsi para MVT y las matrices del WAIS III para SP. Después de realizar los respectivos entrenamientos se encontraron resultados significativos en los diferentes momentos de aplicación. En el grupo experimental se encontraron diferencias en la variable dependiente SP, mientras que en el grupo control en MVT, pero no en la interacción entre grupos ni diferencias entre grupos, lo que sugiere un efecto de familiarización a la prueba.

Capacitação do doente oncológico com doença avançada/cuidador para a gestão da dor em domicílio

Introdução: A dor oncológica é assustadora, tanto para o doente como para o cuidador, quer pela intensidade como por vezes surge, quer pela associação a outros sintomas e alterações nas atividades de vida, causando sofrimento e isolamento social. Capacitar o doente e o cuidador para a gestão da dor, passa por ensinar a identificar, a monitorizar, a relacionar a dor com outros sintomas e com as atividades de vida. Assim como, ensinar a gerir de forma adequada a terapêutica prescrita. Objetivos: Avaliar a aplicação de um programa educativo na capacitação do doente oncológico/cuidador com doença avançada, na gestão da dor em domicílio; Identificar intervenções de Enfermagem no decurso da aplicação do programa; Identificar dificuldades na capacitação do doente/cuidador; Avaliar a capacidade do doente antes e após a aplicação do programa educativo. Metodologia: Este estudo foi realizado no âmbito do projeto de doutoramento. Trata-se de um estudo longitudinal quase experimental, em que foi avaliado o conhecimento relativo à dor antes e depois da aplicação do programa e foi feita uma análise transversal dos registos elaborados pelos participantes, após os vários momentos de contacto/ensino. Participaram no estudo 52 doentes oncológicos com doença avançada, que frequentavam um hospital de dia, em consulta e tratamento sintomático ou curativo de 2ª ou 3ª linha. Resultados: A aplicação do programa educativo exigiu contactos (momentos de ensino) com os participantes, verificandose que 75% dos participantes iniciaram o programa no 1º contacto e 25% iniciaram no 2º contacto. O número de contactos por participante variou entre os 2 e os 6, tendo-se efetuado 3 contactos a 52% dos participantes, 4 a 25% e 2 a 21%. Um participante teve 5 momentos de contacto e outro, 6 momentos. Quanto à capacidade para realização completa dos registos, verificou-se que no final, 50% dos participantes realizaram registos completos de forma independente, destes, 8% adotaram o comportamento correto na tomada da medicação, 6% não modificaram o comportamento e nos restantes esta mudança não se revelou significativa. Trinta e três por cento dos participantes não conseguem realizar os registos sem ajuda, devido ao agravamento dos sintomas, ou baixo nível de literacia, mas identificam e avaliam a dor e outros sintomas. Quinze por cento realizam os registos de forma incompleta e 1 participante apenas descreve a experiência de dor. Conclusões: O desenvolvimento de um programa educativo para capacitação exige uma avaliação do número de momentos de interação necessários para que o processo ocorra. Existem condicionalismos à efetivação dos momentos de contacto, tais como, o estado clínico do doente, a literacia e o desenvolvimento do processo de saúde doença. A aplicação do programa em 3 momentos de ensino foi o mais frequente nesta população. Após a aplicação do programa, a maioria dos doentes/ cuidadores apresentam capacidade para identificar, avaliar e monitorizar a dor e outros sintomas, assim como as alterações nas atividades de vida. Verificou-se uma melhoria na gestão da terapêutica antiálgica.

Auditoria e controlo interno no exército: Relatório de estágio

O Sector Público em Portugal atravessa um momento de viragem. O antigo modelo de gestão, burocrático e autoritário vai, aos poucos, dando lugar a um novo modelo assente no princípio dos três "E(s)"1, economia, eficiência, eficácia, ao qual se pode juntar a sustentabilidade e o respeito pelo ambiente, procura tomar os serviços públicos amigos dos cidadãos e das boas práticas. Esta metamorfose exige, contudo, uma acção concertada não só ao nível das práticas, mas também das mentalidades num trabalho conjunto de governantes gestores e auditores. É hoje indiscutível a importância que a auditoria interna tem no seio das organizações. O sector público começa agora a dar os primeiros passos nesta área procurando através da auditoria, não só evitar fraudes e detectar erros mas também apoiar a gestão através de uma actuação directa e eficaz sobre o que está a acontecer, garantindo que os recursos que são de todos, estão a ser gastos de forma adequada. No Exército já existe uma cultura de auditoria na sua vertente tradicional, ou seja, verificação do passado, efeito persuasor, verificação da legalidade detecção de erros e fraudes. A instituição só pode ganhar se nesta área for pioneira alargando o âmbito, da sua intervenção ao nível da verificação da eficácia e da eficiência melhorando e criando uma cultura de rigor e boas práticas na sua gestão. /ABSTRACT: The public sector in Portugal is at a turning point. The old management, bureaucratic and authoritarian model is gradually giving way to a new model based on the principle of the three "E (s)2”, economy, efficiency, effectiveness and, to which we can join sustainability and environmental respect. It aims at making the public service friendly for citizens and promoting better practices. This metamorphosis, however, requires a harmonized action not only at the practice level but also in the attitudes within a joint effort of governing managers and auditors. It is nowadays· indisputable the importance that internal audit has within organizations. The public sector is beginning to take the first steps in this area, seeking in the audit not only to prevent fraud and detect errors but also to support the management by working directly and effectively on what is happening, ensuring that the resources belong to everyone, and are all being spent properly. ln the Army there is already an audit culture in its traditional area, i.e., verification of the past, persuasive effect, verification of the legality, detecting errors and fraud. The institution can only win if it is pioneer in this area by expanding the scope of its intervention at the level of verification, effectiveness and efficiency, improving and creating a culture of rigor and better practices in its management.

Repensar=Reutilizar. o abandono como oportunidade. Fábrica Robinson: o instante na construção de um tempo provisório

Esta investigação procura mostrar/problematizar programas que questionem a reutilização de lugares, através de uma proposta de projeto provisório de arquitetura, no panorama do Património Industrial, num processo de revitalização. O intuito é procurar modelos/ações que possam responder às transformações, partindo do problema do abandono, dos espaços pós-industriais. O objetivo principal consiste em criar um processo de aproximação à problemática da reutilização cujo processo de elaboração de projeto encontra nas suas formas de produção e operação um discurso que faz a síntese entre prática artística, posição curatorial e arquitetura, na elaboração de um programa para um lugar revitalizando-o. O objeto deste estudo faz parte de uma investigação de pesquisa por projeto e encontra lugar no conjunto arquitetónico da Fábrica Robinson, em Portalegre, cuja apropriação inicial de parte do Convento de S. Francisco dá hoje lugar ao Espaço Robinson. O reconhecimento deste conjunto, como lugar de encontro entre um passado recente e um futuro pendente, marcou a proposta projetual. Proposta de projeto temporário cujo conceito estabelece a viabilidade de apropriação como forma de atuação provisória, subjacente ao ato de reutilizar, criando novos programas de ocupação, promovendo novas ideias e definições de património e assim devolvendo o significado às estruturas industriais vazias. O que preservar e como conservar pode demarcar a importância de salvaguarda deste património e a previsão da sua transmissão para o futuro, fixada pela ideia de preservação. A Fábrica Robinson e a revitalização urbana deste espaço configura, hoje, uma nova oportunidade para estes conjuntos arquitetónicos, e a importância da sua salvaguarda, na valorização do Património Industrial. O trabalho pretende demonstrar a ordem de relação entre programa e lugar no debate interdisciplinar e a hipótese de concretização projetual que preencha um vazio temporalmente suspenso; ABSTRACT: Rethinking = Reuse: The abandonment as opportunity Robinson Factory: The instant in the construction of a provisory time This research aims to show architectural programs that question the reuse of places in the context of industrial heritage, through an architectural design, in a revitalization process. The aim is to look to models / actions that, starting with the abandonment problem, may answer to the post-industrial spaces transformations. The main goal is to create an approximation process to the problem of reuse, whose project design process finds in its production and operations forms a symbiosis between artistic practice, curatioral approach and architecture, in the development of a program to revitalize a place. The object of this study is part of a research project / research by design concerning the architectural complex Fábrica Robinson located in Portalegre, whose original appropriation of part of Convento de S. Francisco is today occupied by Espaço Robinson. The acknowledgment of this complex as a space placed in-between a recent past and a pending future marked the design proposed. A temporary design proposal whose concept establishes the validity of the temporary action, underlying to the act of reuse, creating new occupation programs, promoting new ideas and heritage definitions and thus given back meaning to the empry industrial structures. What to preserve and how to save may mark the importance of safeguarding this heritage and the prediction of its transmission to the future, set by the idea of preservation. The Fábrica Robinson and the urban regeneration of this area sets itself as a new opportunity to safeguard these architectural ensembles and enhance the value of the industrial heritage. This study intend to show the relationship between the program and a vacant place, through a temporary proposal, supported by the interdisciplinary debate and the hypothesis of design implementation that completes a void temporarily suspended.

A influência do modelo e estrutura de recursos humanos na motivação e comprometimento dos trabalhadores: gestão interna versus Outsourcing

Com esta investigação, pretende-se fazer uma análise comparativa sobre o comprometimento e motivação dos trabalhadores, tendo como fator diferencial a gestão do recrutamento, de modo interno e a gestão por outsourcing. O objetivo principal é verificar se existem diferenças significativas nos dois grupos de trabalhadores, à luz de um quadro teórico muito vasto. Para concretizar esta análise foi elaborado um questionário on-line, com questões de escala manifestadas por afirmações elaboradas, com base no enquadramento teórico que constituiu a revisão da literatura, sobre motivação e comprometimento. Os resultados demonstraram que não existem diferenças significativas nos valores médios dos dois grupos na avaliação dos fatores de motivação, embora em ambos os grupos, se verifique uma grande vontade de darem mais de si à organização, de forma a superarem objetivos. Os valores de motivação revelaram-se muito baixos no geral, nos dois grupos. Em ambos os grupos apurou-se que há mais insatisfação face a fatores recompensatórios (tanto a nível material como imaterial): o salário e o reconhecimento do trabalho. Em relação ao comprometimento, verifica-se menor comprometimento por parte dos trabalhadores outsourcing, não numa análise de comparabilidade de médias gerais, mas numa análise de médias mais específicas de alguns fatores em avaliação: intenções de abandono. As médias das intenções de abandono foram mais visíveis neste grupo. No geral, ambos os trabalhadores dos dois grupos são movidos por um comprometimento instrumental, mais relacionado com as poucas alternativas que o mercado de trabalho dispõe , para uma evolução profissional; Abstract: The influence of human resource management structure in the motivation and commitment of employees: internal management versus outsourcing With this research aims to make a comparative analysis on the commitment and motivation of workers, with the differentiating factor the management of the internal mode recruitment and management by outsourcing. The main objective is to verify whether there are significant differences in the two groups of workers in the light of a very broad theoretical framework. To realize this analysis was prepared an online questionnaire with scale issues raised by elaborate statements, based on the theoretical framework that was the literature review of motivation and commitment. The results showed no significant differences in mean values of the two groups in the evaluation of the motivating factors, although in both groups, that there is a great desire to give more of themselves to the organization in order to overcome objectives. The motivation values proved to be very low in general, in both groups. In both groups it was found that there is more dissatisfaction with the recompensatórios factors (both material and immaterial level): wages and recognition of the work. Regarding the commitment, there is less commitment by the outsourcing workers, not an analysis of comparability of overall averages but a more average specific analysis of some factors reviewed abandonment of intentions. The average dropout intentions were more visible in this group. Overall, both employees of the two groups are driven by an instrumental commitment, more related to the few alternatives that the labor market has for professional development.

Canopy-scale biophysical controls of transpiration and evaporation in the Amazon Basin.

Canopy and aerodynamic conductances (gC and gA) are two of the key land surface biophysical variables that control the land surface response of land surface schemes in climate models. Their representation is crucial for predicting transpiration (λET) and evaporation (λEE) flux components of the terrestrial latent heat flux (λE), which has important implications for global climate change and water resource management. By physical integration of radiometric surface temperature (TR) into an integrated framework of the Penman?Monteith and Shuttleworth?Wallace models, we present a novel approach to directly quantify the canopy-scale biophysical controls on λET and λEE over multiple plant functional types (PFTs) in the Amazon Basin. Combining data from six LBA (Large-scale Biosphere-Atmosphere Experiment in Amazonia) eddy covariance tower sites and a TR-driven physically based modeling approach, we identified the canopy-scale feedback-response mechanism between gC, λET, and atmospheric vapor pressure deficit (DA), without using any leaf-scale empirical parameterizations for the modeling. The TR-based model shows minor biophysical control on λET during the wet (rainy) seasons where λET becomes predominantly radiation driven and net radiation (RN) determines 75 to 80 % of the variances of λET. However, biophysical control on λET is dramatically increased during the dry seasons, and particularly the 2005 drought year, explaining 50 to 65 % of the variances of λET, and indicates λET to be substantially soil moisture driven during the rainfall deficit phase. Despite substantial differences in gA between forests and pastures, very similar canopy?atmosphere "coupling" was found in these two biomes due to soil moisture-induced decrease in gC in the pasture. This revealed the pragmatic aspect of the TR-driven model behavior that exhibits a high sensitivity of gC to per unit change in wetness as opposed to gA that is marginally sensitive to surface wetness variability. Our results reveal the occurrence of a significant hysteresis between λET and gC during the dry season for the pasture sites, which is attributed to relatively low soil water availability as compared to the rainforests, likely due to differences in rooting depth between the two systems. Evaporation was significantly influenced by gA for all the PFTs and across all wetness conditions. Our analytical framework logically captures the responses of gC and gA to changes in atmospheric radiation, DA, and surface radiometric temperature, and thus appears to be promising for the improvement of existing land?surface?atmosphere exchange parameterizations across a range of spatial scales.

Canopy-scale biophysical controls of transpiration and evaporation in the Amazon Basin.

Canopy and aerodynamic conductances (gC and gA) are two of the key land surface biophysical variables that control the land surface response of land surface schemes in climate models. Their representation is crucial for predicting transpiration (?ET) and evaporation (?EE) flux components of the terrestrial latent heat flux (?E), which has important implications for global climate change and water resource management. By physical integration of radiometric surface temperature (TR) into an integrated framework of the Penman?Monteith and Shuttleworth?Wallace models, we present a novel approach to directly quantify the canopy-scale biophysical controls on ?ET and ?EE over multiple plant functional types (PFTs) in the Amazon Basin. Combining data from six LBA (Large-scale Biosphere-Atmosphere Experiment in Amazonia) eddy covariance tower sites and a TR-driven physically based modeling approach, we identified the canopy-scale feedback-response mechanism between gC, ?ET, and atmospheric vapor pressure deficit (DA), without using any leaf-scale empirical parameterizations for the modeling.

A multi-disciplinary approach for the design and management of airport terminals

Multi-disciplinary approaches to complex problems are becoming more common – they enable criteria manifested in distinct (and potentially conflicting) domains to be jointly balanced and satisfied. In this paper we present airport terminals as a case study which requires multi-disciplinary knowledge in order to balance conflicting security, economic and passenger-driven needs and correspondingly enhance the design, management and operation of airport terminals. The need for a truly multi-disciplinary scientific approach which integrates information, process, people, technology and space domains is highlighted through a brief discussion of two challenges currently faced by airport operators. The paper outlines the approach taken by this project, detailing the aims and objectives of each of seven diverse research programs.

Implementing value management as a decision-making tool in the design stages of design and build construction projects : a methodology for improved cost optimization

Value Management (VM) has been proven to provide a structured framework, together with other supporting tools and techniques, that facilitate effective decision-making in many types of projects, thus achieving ‘best value’ for clients. One of the major success factors of VM in achieving better project objectives for clients is through the provision of beneficial input by multi-disciplinary team members being involved in critical decision-making discussions during the early stage of construction projects. This paper describes a doctoral research proposal based on the application of VM in design and build construction projects, especially focusing on the design stage. The research aims to study the effects of implementing VM in design and build construction projects, in particular how well the methodology addresses issues related to cost overruns resulting from poor coordination and overlooking of critical constructability issues amongst team members in construction projects in Malaysia. It is proposed that through contractors’ early involvement during the design stage, combined with the use of the VM methodology, particularly as a decision-making tool, better optimization of construction cost can be achieved, thus promoting more efficient and effective constructability. The main methods used in this research involve a thorough literature study, semi-structured interviews, and a survey of major stakeholders, a detailed case study and a VM workshop and focus group discussions involving construction professionals in order to explore and possibly develop a framework and a specific methodology for the facilitating successful application of VM within design and build construction projects.
