Analysis and visualization of energy use for university campus

The reduction of greenhouse gas emissions is one of the big global challenges for the next decades due to its severe impact on the atmosphere that leads to a change in the climate and other environmental factors. One of the main sources of greenhouse gas is energy consumption, therefore a number of initiatives and calls for awareness and sustainability in energy use are issued among different types of institutional and organizations. The European Council adopted in 2007 energy and climate change objectives for 20% improvement until 2020. All European countries are required to use energy with more efficiency. Several steps could be conducted for energy reduction: understanding the buildings behavior through time, revealing the factors that influence the consumption, applying the right measurement for reduction and sustainability, visualizing the hidden connection between our daily habits impacts on the natural world and promoting to more sustainable life. Researchers have suggested that feedback visualization can effectively encourage conservation with energy reduction rate of 18%. Furthermore, researchers have contributed to the identification process of a set of factors which are very likely to influence consumption. Such as occupancy level, occupants behavior, environmental conditions, building thermal envelope, climate zones, etc. Nowadays, the amount of energy consumption at the university campuses are huge and it needs great effort to meet the reduction requested by European Council as well as the cost reduction. Thus, the present study was performed on the university buildings as a use case to: a. Investigate the most dynamic influence factors on energy consumption in campus; b. Implement prediction model for electricity consumption using different techniques, such as the traditional regression way and the alternative machine learning techniques; and c. Assist energy management by providing a real time energy feedback and visualization in campus for more awareness and better decision making. This methodology is implemented to the use case of University Jaume I (UJI), located in Castellon, Spain.

Caracterização do papel dos genes TYMS e MTR no desenvolvimento de Cancro Colo-Rectal

RESUMO: O cancro colo-rectal (CCR) é um dos cancros que possui maior taxa de mortalidade a nível mundial. Em Portugal esta patologia é responsável pela morte de cerca de 3700 pessoas por ano, sendo que estes números aumentam de ano para ano. Ao longo das últimas décadas o papel das alterações genéticas na etiologia das patologias oncológicas tem vindo a ter cada vez mais um maior destaque. O número de estudos que avaliam a importância de polimorfismos, mutações, alterações na regulação génica e interacções entre genes no desenvolvimento destas patologias tem aumentado exponencialmente. Com o aumento do conhecimento da forma como estas alterações influenciam o desenvolvimento do cancro surgiram os primeiros meios de diagnóstico genético, levando assim a uma alteração da forma como são encarados o diagnóstico e a prevenção destas doenças. No CCR as formas hereditárias com alterações genéticas inequivocamente identificadas representam apenas 5% dos casos. Existem cerca de 25% que representam formas hereditárias para as quais ainda não foram estabelecidos os padrões de alterações genéticas subjacentes. Desta forma, estudos que venham contribuir para um maior conhecimento dos mecanismos moleculares responsáveis pelo aumento da susceptibilidade dos indivíduos para o desenvolvimento de CCR são extremamente importantes. O CCR é uma patologia multifactorial, onde factores genéticos interagem com factores ambientais no surgimento e desenvolvimento da doença. Assim, torna-se essencial integrar o estudo das alterações genéticas no contexto ambiental onde os indivíduos em estudo se encontram. No caso desta patologia um dos principais factores ambientais estudado é a nutrição. Vários estudos têm sido realizados ao longo dos últimos anos de forma a compreender como pode a ingestão dos nutrientes influenciar o desenvolvimento de CCR e de que forma interage com as alterações genéticas individuais. O ciclo do folato é um dos processos metabólicos onde o papel da nutrição em interacção com alterações genéticas mais tem sido estudado nos últimos anos. Deste cruzamento entre o estudo das alterações genéticas e ambientais surge a Nutrigenética. O conjunto de estudos da presente tese tem como objectivo aumentar o conhecimento do papel das alterações em genes do ciclo do folato, em interacção com factores nutricionais e de estilo de vida, não só no desenvolvimento de CCR, mas também de outra patologia do tracto gastrointestinal, a Doença de Crohn (DC), uma doença inflamatória muitas vezes associada como factor de risco para o desenvolvimento de CCR. Este estudo debruçou-se essencialmente no estudo dos genes timidilato sintetase (TYMS) e metionina sintetase (MTR) em populações com CCR e DC, bem como no padrão nutricional destas populações com particular incidência nos nutrientes envolvidos no ciclo do folato (folato, metionina, vitamina B6, vitamina B12). Analisando o conjunto de resultados obtidos para os estudos do CCR podemos concluir que quer a TYMS quer a MTR possuem um papel relevante na susceptibilidade para desenvolver esta patologia, assim como têm destaque no funcionamento do ciclo celular durante o processo oncogénico. Os resultados demonstram que os factores que levam a uma menor disponibilidade de grupos metil no ciclo de folato (baixos níveis de folato, alteração da actividade de MTR, elevada expressão de TYMS) constituem factores de risco, muito provavelmente por contribuírem para uma desregulação dos níveis de metionina disponível para a metilação do DNA da célula. Demonstram ainda que em células tumorais ocorrem alterações na regulação do ciclo do folato de forma a favorecer a síntese de DNA em detrimento da metilação do mesmo, alterando para isso a expressão dos genes de forma a que o fluxo de grupos metil provenientes do folato sejam encaminhados para a enzima TYMS. O polimorfismo de deleção 6pb da TYMS surge como um factor de diagnóstico e de prognóstico de CCR para a população portuguesa. Dos factores nutricionais analisados apenas o folato aparenta ter um papel relevante na modelação do risco de desenvolver CCR. Na doença de Crohn (DC) podemos verificar que a homocisteína e o seu metabolismo poderão contribuir para o aparecimento e desenvolvimento da patologia. O aumento da homocisteína poderá ser o responsável por um aumento da resposta auto-imune do organismo, promovendo o aparecimento da DC. O polimorfismo A2756G MTR desempenha um papel preponderante como factor de diagnóstico da DC, tendo sido associado pela primeira vez a esta patologia. Tem também um papel importante no desenvolvimento da doença, uma vez que está associado a uma idade de diagnóstico mais baixa, sugerindo assim que o desenvolvimento da doença ocorre de forma mais precoce. Concluindo, com este estudo pensamos ter contribuído para um melhor entendimento do papel do ciclo do folato no desenvolvimento de CCR e DC, sendo um ponto de partida para futuras investigações que possam revelar cada vez melhor as complexas interacções metabólicas desta via e a sua influência nas patologias estudadas. Do nosso estudo destacamos a importância de uma análise global das várias etapas do ciclo do folato para que se possa compreender a dinâmica que se estabelece no desenvolvimento destas patologias, podendo diversas alterações, quer a nível genético quer a nível nutricional, exercerem efeitos diferentes consoante o estado dos restantes intervenientes do ciclo do folato. Acreditamos que no futuro este estudo permitirá que o conhecimento do ciclo do folato tenha cada vez mais uma relevância fundamental a nível de diagnóstico e terapêutica destas patologias.------------ ABSTRACT: Colorectal Cancer (CRC) is one of the cancers that have a higher rate of mortality worldwide. In Portugal this pathology is responsible for the deaths of about 3700 people per year, and these numbers increase each year. Over the past few decades the role of genetic changes in the etiology of oncological pathologies has had an increasingly greater emphasis. The number of studies that evaluate the importance of polymorphisms, mutations, changes in gene regulation and gene interactions in the development of these diseases has increased exponentially. With the increased knowledge of how these changes influence the development of cancer, appeared the first means for genetic diagnostic, leading to a change in the way diagnosis is seen and in the prevention of these diseases. In CRC the hereditary forms with clearly identified genetic changes represent only 5% of cases. There are about 25% representing hereditary forms for which the patterns of genetic changes haven’t been established. In this way, studies that will contribute to a greater understanding of the molecular mechanisms responsible for increased susceptibility of individuals to the CRC development are extremely important. CRC is a multifactorial pathology, where genetic factors interact with environmental factors in the emergence and development of the disease.Thus, it is essential to integrate the study of genetic changes in the environmental context of the individuals under study. In the case of this pathology one of the main environmental factors studied is nutrition. Several studies have been conducted over the past few years in order to understand how the intake of nutrients can influence the development of CRC and how nutrients interact with the individual genetic changes. The folate cycle is one of the metabolic processes where the role of nutrition in interaction with genetic alterations has been studied in recent years. This cross between the study of genetic and environmental changes developed Nutrigenetics. The set of studies of this thesis aims to increase awareness of the role of changes in genes of the folate cycle, in interaction with nutritional factors and lifestyle, not only in the development of CRC, but also of another pathology of the gastrointestinal tract, Crohn's disease (CD), an inflammatory disease often associated as a risk factor for the development of CRC. This study dealt mainly in the study of genes thymidylate synthase (TYMS) and methionine synthase (MTR) in populations with CRC and CD, as well as in the nutritional pattern of these populations with particular focus on nutrients involved in the folate cycle (folate, methionine, vitamin B6, vitamin B12). Analyzing the results obtained for the CRC studies we conclude that either the MTR TYMS have a relevant role in susceptibility to develop this pathology, and have an important role in the functioning of the cell cycle during oncogenesis. The results show that the factors that lead to a lower availability of methyl groups in folate cycle (low levels of folate, change the activity of MTR, high expression of TYMS) constitute risk factors, most likely by contribute to a dysregulation of methionine levels available for DNA methylation of the cell. Our results also demonstrate that in tumor cells occur changes in the regulation of the folate cycle in order to promote the synthesis of DNA, to the detriment of methylation of the same by changing the expression of genes so that the methyl groups from folate are forwarded to the TYMS enzyme reaction. The deletion polymorphism 6bp of TYMS emerges as a diagnostic and prognostic factor of CCR for the Portuguese population. Nutritional factors analyzed only folate appears to have a major role in modulating the risk of developing CCR.In Crohn’s disease (CD) we can check that homocysteine and its metabolism may contribute to the emergence and development of this pathology. Increased homocysteine may be responsible for an increase in the body's autoimmune response, promoting the emergence of CD. The polymorphism A2756G MTR plays a leading role as a factor of diagnosis of DC, having been associated with this pathology for the first time. It also has an important role in the development of the disease, since it is associated with a lower diagnostic age, suggesting that the development of the disease occurs earlier. In conclusion, our study has contributed to a better understanding of the role of folate cycle in the development of CRC and CD, being a starting point for future research that may prove increasingly complex metabolic interactions in this via and its influence on the pathologies studied. In our study we highlight the importance of a comprehensive analysis of the various steps of the folate cycle in order to understand the dynamics that settles in the development of these pathologies, and a number of amendments, whether at the genetic level or at the nutritional level, exercise different effects depending on the stage of the remaining participants in the folate cycle. We believe that in the future this study will allow the knowledge of folate cycle to have increasingly a fundamental relevance at the level of diagnosis and treatment of these diseases.

O transporte como determinante social de saúde : mobilidade e utilização de transportes públicos na perceção das pessoas idosas : um estudo de caso numa comunidade urbana

RESUMO - O crescimento da população idosa constitui um dos principais desafios para as atuais e futuras sociedades. A possibilidade de as pessoas permanecerem na sua comunidade de forma saudável e ativa, à medida que envelhecem, elevam a importância da questão da mobilidade e da forma como se deslocam, na saúde e qualidade de vida desta população. O presente trabalho propôs-se perceber de que forma o acesso a transporte influencia a saúde e qualidade de vida, na perspetiva das pessoas idosas e identificar fatores que atuassem como barreiras ao acesso e utilização de transportes, principalmente transportes públicos. A metodologia utilizada foi estudo de caso, com base no modelo PRECEDEPROCEED, desenvolvido na Ameixoeira, Lisboa. Os dados resultaram de um questionário aplicado a 24 pessoas idosas, da análise documental e da realização de entrevistas. A análise dos dados sugere que, é ao nível da autonomia e independência que o acesso a transporte influencia a saúde e a qualidade de vida da amostra, e a mobilidade e utilização de transporte, por sua vez, é influenciada por fatores individuais, como a idade, o género, o rendimento e as condições de saúde, e fatores ambientais envolvendo características dos transportes e da zona de residência. Tendo-se focado o trabalho na identificação das barreiras percecionadas pelas pessoas idosas na utilização de transportes públicos, sugere-se o elevado preço, a insuficiente distribuição do serviço, a distância às paragens e os horários inadequados como os principais constrangimentos identificados. Embora os resultados não possam ser extrapolados, devem ser encarados como um ponto de partida para futuras investigações.

Proportion, (dis)Harmonies, Identities

Number, dimension, geometric constructions, and the relationship between dimensions, proportion, are expressions of harmony and rhythm and considered a source of beauty in the things of nature, like crystals, plants, and animals, but also in human artefacts, as buildings and art in general. This is an old idea, which corresponds to the Pythagorean notion that the world is a harmonious mathematical creation and that in order to attend such harmony, the things we do have to obey the same mathematical laws. Proportion (dis)Harmonies and Identities, aims to promote awareness and reflection on the importance of this issue with the dissemination of researches of various fields of knowledge.

Seat in China

Currently, China has the biggest automobile industry in the world. China’s economic situation helped the automobile market, as the internal demand of passenger cars increased substantially in the last years. Chinese automobile industry’s astonishing expansion over the past years has attracted many foreign automobile groups. SEAT decided to enter the Chinese market, following its expansion strategy to enter new markets. The purpose of this study is to analyse and understand the strategic entry of SEAT in the Chinese market, hence the choice of an explanatory case study (Yin, 2003). This study extends this analysis by examining the chines automobile market, more specifically the demand, the market segmentation and the intensity of competition, reviewing the SEAT company history, their competitive positioning and resources. I conclude that, although the Chinese market has growing potential, SEAT has failed to achieve its initial objective. The company has not been able to create a brand awareness in the Chinese market, unlike other foreign brands that have managed to accomplish that. This occurred, mostly, because of the high prices in comparison to its competitors due to additional import cost, such as import duties, transportation and distribution.

Help-seeking for 'memory loss' by older adults in India : patient, caregiver and health providers' perspectives

ABSTRACT: Background. In India, prevalence rates of dementia and prodromal amnestic Mild Cognitive Impairment (MCI) are 3.1% and 4.3% respectively. Most Indians refer to the full spectrum of cognitive disorders simply as ‘memory loss.’ Barring prevention or cure, these conditions will rise rapidly with population aging. Evidence-based policies and practices can improve the lives of affected individuals and their caregivers, but will require timely and sustained uptake. Objectives. Framed by social cognitive theories of health behavior, this study explores the knowledge, attitudes and practices concerning cognitive impairment and related service use by older adults who screen positive for MCI, their primary caregivers, and health providers. Methods. I used the Montreal Cognitive Assessment to screen for cognitive impairment in memory camps in Mumbai. To achieve sampling diversity, I used maximum variation sampling. Ten adults aged 60+ who had no significant functional impairment but screened positive for MCI and their caregivers participated in separate focus groups. Four other such dyads and six doctors/ traditional healers completed in-depth interviews. Data were translated from Hindi or Marathi to English and analyzed in Atlas.ti using Framework Analysis. Findings. Knowledge and awareness of cognitive impairment and available resources were very low. Physicians attributed the condition to disease-induced pathology while lay persons blamed brain malfunction due to normal aging. Main attitudes were that this condition is not a disease, is not serious and/or is not treatable, and that it evokes stigma toward and among impaired persons, their families and providers. Low knowledge and poor attitudes impeded help-seeking. Conclusions. Cognitive disorders of aging will take a heavy toll on private lives and public resources in developing countries. Early detection, accurate diagnosis, systematic monitoring and quality care are needed to compress the period of morbidity and promote quality of life. Key stakeholders provide essential insights into how scientific and indigenous knowledge and sociocultural attitudes affect use and provision of resources.

Assessment by doppler ultrasound of entheseal lesions in spondyloarthritis : a longitudial study to determine structural damage and disease activity lesions

RESUMO: Enthesitis is the hallmark of spondyloarthritis (SpA), and is observed in all subtypes. Wide information on SpA abnormalities, including synovitis, tendinitis and enthesitis, can be efficiently perceived by Doppler ultrasound. Furthermore, several studies on imaging of enthesis showed that imaging techniques are better than clinical examination to detect enthesis alterations; and vascularized enthesitis detected by Doppler ultrasound appears to be a valuable diagnostic tool to confirm SpA diagnosis. However, data published until now concerning entheseal elementary alterations that characterize SpA enthesitis (enthesis inflammatory activity) or enthesopathy (permanent structural changes) reflect rather the authors’ empiric opinion than a methodological validation process. In this sense it seems crucial to identify elementary entheseal lesions associated with activity or damage, in order to improve monitoring and treatment response in SpA patients. The development of better assessment tools is today a challenge and a need in SpA. The first study of this thesis focused on the analysis of the reliability of inter-lector and inter-ultrasonography equipment of Madrid sonography enthesitis index (MASEI). Fundamental data for the remaining unrolling project validity. In the second and third studies we concerned about two entheseal elemental lesions: erosions and bursa. In literature erosions represent a permanent structural damage, being useful for monitoring joint injury, disease activity and therapeutic response in many rheumatic diseases; and to date, this concept has been mostly applied in rheumatoid arthritis (RA). Unquestionably, erosion is a tissue-related damage and a structural change. However, the hypothesis that we decided to test was if erosions represent a permanent structural change that can only grow and worsen over time, as occurs in RA, or a transitory alteration. A longitudinal study of early SpA patients was undertaken, and the Achilles enthesis was used as a model. Our results strongly suggested that previously detected erosions could disappear during the course of the disease, being consistent with the dynamic behavior of erosion over time. Based on these striking results it seems reasonable to suggest that the new-bone formation process in SpA could be associated with the resolution of cortical entheseal erosion over time. These results could also be in agreement with the apparent failure of anti-tumor necrosis factor (TNF) therapies to control bone proliferation in SpA; and with the relation of TNF-α, Dickkopf-related protein 1 (Dkk-1) and the regulatory molecule of the Wnt signaling pathway in the bone proliferation in SpA. In the same model, we then proceeded to study the enthesis bursa. Interestingly, the Outcome Measures in Rheumatology Clinical Trials (OMERACT) enthesopathy definition does not include bursa as an elementary entheseal lesion. Nonetheless, bursa was included in 46% of the enthesis studies in a recently systematic literature review, being in agreement with the concept of “synovio-entheseal complex” that includes the link between enthesitis and osteitis in SpA. It has been clarified in recent data that there is not only a close functional integration of the enthesis with the neighboring bone, but also a connection between enthesitis and synovitis. Therefore, we tried to assess the prevalence and relevance of the bursa-synovial lesion in SpA. Our findings showed a significant increase of Achilles bursa presence and thickness in SpA patients compared to controls (healthy/mechanical controls and RA controls). These results raise awareness to the need to improve the enthesopathy ultrasonographic definition. In the final work of this thesis, we have explored new perspectives, not previously reported, about construct validity of enthesis ultrasound as a possible activity outcome in SpA. We performed a longitudinal Achilles enthesis ultrasound study in patients with early SpA. Achilles ultrasound examinations were performed at baseline, six- and twelve-month time periods and compared with clinical outcome measures collected at basal visit. Our results showed that basal erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are higher in patients with Doppler signal in enthesis, and even that higher basal ESR, CRP and Ankylosing Spondylitis Disease Activity Score (ASDAS) predicted a higher Doppler signal (an ultrasound alteration accepted as representative of inflammation) six months later. Patients with very high disease activity assessed by ASDAS (>3.5) at baseline had significantly higher Achilles total ultrasound score verified at the same time; and ASDAS <1.3 predicted no Doppler signal at six and twelve months. This seems to represent a connection between classical biomarkers and clinical outcomes associated with SpA activity and Doppler signal, not only at the same time, but also for the following months. Remarkably, patients with inactive disease (ASDAS < 1.3) at baseline had no Doppler signal at six and twelve months. These findings reinforce the potential use of ultrasound related techniques for disease progression assessment and prognosis purposes. Intriguingly, Ankylosing Spondylitis Disease Activity Index (BASDAI) didn’t show significant differences between different cut-offs concerning ultrasound lesions or Doppler signal, while verified with ASDAS. These results seem to indicate that ASDAS reflects better than BASDAI what happens in the enthesis. The work herein discussed clearly shows the potential utility of ultrasound in enthesis assessment in SpA patients, and can be important for the development of ultrasound activity and structural damage scores for diagnosis and monitoring purposes. Therefore, local promotion of this technique constitutes a medical intervention that is worth being tested in SpA patients for diagnosis, monitoring and prognosis purposes.

Fatores de risco no patrulhamento da GNR em ambiente operacional

In the mid-twentieth century, Portugal took the first big step towards social awareness of the Safety and Health at Work. Still later, the International Labour Organization and the World Health Organization were responsible for setting global guidelines that clarified the States for the way forward in inguito of safeguarding the common interests of workers, businesses and the state. All workers should be covered by the rules governing matters relating to Safety, imperative requirements established in the Constitution of the Portuguese Republic. These also include those soldiers from National Guard who, in contemporary social conjecture face in their everyday life situations worthy of heightened risk aquidade. Ensure the identification of risk factors to which they are exposed, is, first, a big boost in the way of preserving the safety of these employees, who daily selflessly and under the most adverse working conditions fulfill the mission of the Guarda Nacional Republicana. Adverse weather conditions, and violence at work are two examples of risk factors to which the military Guard are daily exposed, and hence arise many days of absence from the workplace. The purpose of this study is to identify the main risk factors to which the military from GNR are exposed during dismounted patrols, and also provide solutions on ways to mitigate and manage the risks presented. The cognitive distance traveled, throughout this study led us to demonstrate that it has been done by the GNR chain of Command, a huge effort to ensure through various forms (including emphasize the new Regulation of Uniforms), the resolution of the main factors that may jeopardize the integrity of the patrolmen, betting this Institution in the protection of the military that compose it, and the prevention of accidents at work through training and systematic monitoring that superiors expend with its employees.

The efficacy of the old way/new way methodology on the correction of an automated technical error and its impact on the athlete’s psychological skills : Case study in tennis

The aim of this study was to evaluated the efficacy of the Old Way/New Way methodology (Lyndon, 1989/2000) with regard to the permanent correction of a consolidated and automated technical error experienced by a tennis athlete (who is 18 years old and has been engaged in practice mode for about 6 years) in the execution of serves. Additionally, the study assessed the impact of intervention on the athlete’s psychological skills. An individualized intervention was designed using strategies that aimed to produce a) a detailed analysis of the error using video images; b) an increased kinaesthetic awareness; c) a reactivation of memory error; d) the discrimination and generalization of the correct motor action. The athlete’s psychological skills were measured with a Portuguese version of the Psychological Skills Inventory for Sports (Cruz & Viana, 1993). After the intervention, the technical error was corrected with great efficacy and an increase in the athlete’s psychological skills was verified. This study demonstrates the methodology’s efficacy, which is consistent with the effects of this type of intervention in different contexts.

Southern Modernisms. Critical Stances through Regional Appropriations. Conference proceedings

The hegemonic definition of Modernism has been subjected to an intense critical revision process that began several decades ago. This process has contributed to the significant broadening of the modernist canon by challenging its primal essentialist assumptions and formalist interpretations in the fields of both the visual arts and architecture. This conference aims to further expand this revision, as it seeks to discuss the notion of “Southern Modernisms” by considering the hypothesis that regional appropriations, both in Southern Europe and the Southern hemisphere, entailed important critical stances that have remained unseen or poorly explored by art and architectural historians. In association with the Southern Modernisms research project (FCT – EXPL/CPC-HAT/0191/2013), we want to consider the entrenchment of southern modernisms in popular culture (folk art and vernacular architecture) as anticipating some of the premises of what would later become known as critical regionalism. It is therefore our purpose to explore a research path that runs parallel to key claims on modernism’s intertwinement with bourgeois society and mass culture, by questioning the idea that an aesthetically significant regionalism – one that resists to the colonization of international styles and is supported by critical awareness – occurred only in the field of architecture, and can only be represented as a postmodernist turn.
