A partir de estudos de Avaliação de Ciclo de Vida (ACV), tem-se desenvolvido estratégias de otimização das etapas complexas que essa requer, através da Avaliação de Ciclo de Vida Energético (ACVE). Este trabalho buscou discutir a ACVE nas etapas de pré-uso, uso e manutenção e desconstrução de um projeto típico de habitação térrea para o Distrito Federal no Brasil, de 45,64 m², abordando os sistemas de vedação vertical internos e externos. As vedações abordadas foram parede de concreto moldadas no local, alvenaria estrutural de blocos de concreto, steel frame e convencional. Buscou-se também realizar ensaios com a finalidade de obter a EI para a fase de desconstrução, abordando também a EI dos resíduos. Como resultados, verificou-se que as vedações em alvenaria estrutural apresentaram menor EI total. Em todas as situações, a etapa de desconstrução comportou-se como sendo a de menor EI, representando em média 1% da EI total. A etapa de uso e manutenção teve a maior EI para os sistemas abordados. Já a etapa de pré-uso teve maior EI para dois sistemas, sendo as vedações de painéis de concreto com apenas uma utilização das fôrmas e as vedações em steel frame, o qual apresentou no conjunto das três etapas a maior EI total. A partir da análise dos resíduos das vedações na etapa de desconstrução, encontraram-se resultados de que os resíduos podem representar de 6 (seis)% até 11 (onze)% da EI total. Os estudos mostraram que nas condições específicas da pesquisa, os valores para EI total para as vedações foram de 13,17 GJ/m² até 31,99 GJ/m². ________________________________________________________________________________________________ ABSTRACT / The study of embodied energy (EE) in the research context of sustainability on the construction supply chain has contributed for science and technology in Brazil, but the researches are still incipient. Based on studies on Energy Life Cycle Assessment (Energy LCA), some strategies to optimize the complex phases of Life Cycle Assessment (LCA) have been developed. This work discuss Energy LCA in the pre-use, use as well as demolition phases of a typical project of a social housing of one story of 45,64 m² in Distrito Federal, situated in Brazil. The thesis addresses internal and external walls. They addressed walls were concrete wall molded-in-place, structural masonry of concrete block, steel frame and traditional masonry. Tests were made to obtain the EE in the demolition phase, addressing EE of remnants. As a result, it was possible to verify that the structural masonry wasted less total EE than the others. In every analyzed situation, the demolition phase was the one that wasted less EE, representing 1% of the total EE. The use phase consumed the most part of the EE. The pre-use phase consumed the most part of the EE for concrete wall when it uses just one form and for steel frame which presents the higher spending of total EE throughout the three phases. Based on the analyze of the remnants of the internal and external walls in the demolition stage, the remnants can represent from 6% to 11% of total EE.The studies indicated that the amount of total EE for internal and external walls were from 13,17 GJ/m² to 31,99 GJ/m², at the specific conditions of this research.

The purpose of this study was to identify characteristics pertaining to emotional intelligence (EI) that parents and Foundation Phase teachers may use when supporting learners with autism spectrum disorder (ASD) in an inclusive classroom setting. Teachers are facing various degrees of challenges due to the demands of a range of diverse needs attributable to the influx of learners with disabilities in the school system. Given the increase in the number of children diagnosed with ASD, research indicates that it is likely that teachers will encounter learners with ASD in their classes. Teachers are generally not trained to identify and cope with such a disability, as many requirements of these learners are beyond the services of a general school system. A multiple case study was conducted where the perspectives of a teacher and two parents were gained, in order to understand experiences with children with ASD from the participants' point of view. The primary aim of this study was therefore to provide both parents and teachers with listed characteristics of EI that they could utilise while supporting learners with ASD in households or the educational sphere. Findings illuminated the collective characteristics of learners with ASD, which include intense obsessions with a narrow range of subjects, repetitive routines, central coherence difficulties and problems with social-emotional functioning, communication and executive functioning. These indicators require specific responses from parents and teachers to effectively provide support to these learners. Qualities identified that relate to EI are patience, empathy, problem solving skills, working collaboratively with parents and being proactive. The main recommendation relates to specific training in EI skills, to prepare student teachers in supporting the growing number of learners with ASD in their classes. / Dissertation (MEd)--University of Pretoria, 2017. / Early Childhood Education / MEd / Unrestricted

A method to detect nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) in the air has been developed using gas chromatography with an atmospheric pressure chemical ionisation source, coupled to a triple quadrupole mass spectrometer (GC-APCI-MS/MS). An attempt to create a GC method using negative chemical ionisation (NCI) and a high-resolution mass spectrometer, Orbitrap, (GC-NCI-MS) was made as well without success. Nitro-PAHs are a group of widespread contaminants considered as possible mutagens and carcinogens. They are formed from incomplete combustion of organic matter as well as secondary reactions between PAHs and nitrogen dioxide (NO2) in the air. Three air samples (outdoor, in an air vent and indoor), both particulate and gaseous phase, collected in central Örebro during the spring were extracted and analysed for nitro-PAHs on GC-APCI-MS/MS and for PAHs on GC-MS in EI (electron ionisation) mode. Several studies have reported lower amounts of nitro-PAHs than PAHs in the air, which can be seen in this report as well. The levels of detected nitro-PAHs (1-nitronaphalene and 9-nitroanthracene) and PAHs (naphthalene, anthracene, fluoranthene and pyrene) in the different samples were 10.2-119 pg/m3 and 291-77700 pg/m3, respectively. Neither group of analytes were found in the particulate phase. The highest concentrations of both nitro-PAHs and PAHs were found indoors, suggesting that other sources than emissions from traffic are responsible.

This study was commissioned by Umeå Energi under the supervision of Rejlers. The assignment consisted of investigating how electricity production facilities affected the grid utility in the region's electricity grid. As the Energy Market Inspectorate in PM - Ei PM2020: 04 developed new calculation methods of grid utility compensation, these were applied in the study. The calculations were then made at four production facilities in the Umeå region's electricity network. In calculations in the study, four calculation variants based on Ei:s Method 2020 were also used. This was due to ambiguities in Ei's memorandum and what the region's tariff setting looked like at low and high load times. For each plant, a retroactive hourly compensation was also developed in relation to the plant's produced energy. What emerged was that each electricity generation plant has an individual impact on grid utility, regardless of the power plant's power type. It also turned out that the compensation varied depending on how the memorandum from Ei was interpreted. The discussion indicates that the network utility compensation has been developed so that the production owner will receive fair compensation. The results also show the challenge of determining a fair grid utility benefit compensation in advance.As a result, retroactive calculations of compensation will there fore be preferred to obtain the actual plant's network's net benefit. / Denna studie har gjorts på uppdrag av Umeå Energi med handledning av Rejlers. Uppdraget bestod av att undersöka hur elproduktionsanläggningar påverkade nätnyttan i regionens elnät. I och med att  energimarknadsinspektionen i PM - Ei PM2020:04 tagit fram nya beräkningsmetoder av nätnyttoersättning så tillämpades dessa i studien. Beräkningarna gjordes sedan på fyra produktionsanläggningar i Umeåregionens elnät. Vid beräkningar i studien användes även fyra beräkningsvarianter baserade på Ei:s Metod 2020. Detta till följd av tvetydigheter i Ei:s promemoria samt hur regionens tariffsättning såg ut vid låg- och höglasttider. För varje anläggning togs även en retroaktiv timbaserad ersättning fram i förhållande till anläggningens producerade energi.  Det som framkom var att varje elproduktionsanläggning har en individuell påverkan av nätnytta, oberoende av produktionsanläggningens kraftslag. Det visade sig också att ersättningen varierade beroende på hur promemorian från Ei tolkas. Diskussionen indikerar på att nätnyttoersättningen är framtagen för att produktionsinnehavaren ska få en rättvisande ersättning. Resultatet visar även på utmaningen med att bestämma en rättvisande nätnyttoersättning i förväg.Därav blir retroaktiva beräkningar av ersättning att fördra för att få fram produktionsanläggningens faktiska nätnytta.

Cette thèse porte sur l'estimation simultanée du coefficient de diffusion et du terme source régissant le modèle de transport de la température dans les plasmas chauds. Ce phénomène physique est décrit par une équation différentielle partielle (EDP) linéaire, parabolique du second-ordre et non-homogène, où le coefficient de diffusion est distribué et le coefficient de réaction est constant. Ce travail peut se présenter en deux parties. Dans la première, le problème d'estimation est traité en dimension finie ("Early lumping approach"). Dans la deuxième partie, le problème d'estimation est traité dans le cadre initial de la dimension infinie ("Late lumping approach"). Pour l'estimation en dimension finie, une fois le modèle établi, la formulation de Galerkin et la méthode d'approximation par projection sont choisies pour convertir l'EDP de transport en un système d'état linéaire, temps-variant et à entrées inconnues. Sur le modèle réduit, deux techniques dédiées à l'estimation des entrées inconnues sont choisies pour résoudre le problème. En dimension infinie, l'estimation en-ligne adaptative est adoptée pour apporter des éléments de réponse aux contraintes et limitations dues à la réduction du modèle. Des résultats de simulations sur des données réelles et simulées sont présentées dans ce mémoire.

The study explores the project manager’s perception of the competitive dynamic amongst the projects that utilize the same organizational resources in the multi-project context.   The method used is a qualitative research design with an inductive approach where the data corpus was analyzed through thematic analysis. Ten project managers with experience in multi-project environments participated in the study. The analysis resulted in three themes. Theme 1: Competing is outdated and unsavory with the sub-themes No competition, we work together, and Friendly competition for a common goal. This theme reflects the respondents’ perception of the competitive dynamic between the projects. Theme 2: Organization set precedent with the sub-theme Governance of projects shows the respondents’ perception of their work situation with the complex nature of projects. Theme 3: Obstacles are unsolved solutions with the sub-theme Do the best you can with what you got and be a good sport about it; demonstrates the respondents’ attitudes, behavior, and view of their part in the dynamic between the other projects, the project managers, and the rest of the organization. Unexpectedly, the respondents did not appear to agree that there are competing dynamics amongst the projects that utilize the same organizational resources in multi-project organizations. Instead, many respondents were averse to competing and saw it as outdated and problematic for the organization’s success and the work environment. The results show that the respondents prefer cooperation instead of competing and choose to prioritize interpersonal relationships with their fellow project managers instead.

In this study, the author provided a discussion of international cross-cultural validation studies which reported low internal consistency reliabilities for the self-motivation facet of the Trait Emotional Intelligence Questionnaire (TEIQue). A review of salient models of emotional intelligence (EI) revealed that self-motivation was consistently conceptualised as part of the sampling domain of trait and mixed models of EI, but not ability-based conceptualisations of the construct. The author provided a qualitative evaluation of the ten self-motivation test items as they appeared in the TEIQue with the purpose of exploring the operationalisation of the construct in a multi-cultural South African sample. The exploratory-descriptive research was conducted amongst permanent employees who have all completed the TEIQue as part of on-going employee assessments. The present study found limited support for a satisfactory operationalisation of the self-motivation facet of the TEIQue as it related to a multi-cultural South African research sample. / Psychology / M.A. (Psychology)

Viena labiausiai paplitusių internetinių informacinių sistemų rūšių yra intranetas. Tai organizacijos tinklas, grindžiamas interneto protokolų rinkiniu TCP/IP. Pagrindinė intraneto paskirtis – komunikacija ir bendradarbiavimas tarp organizacijos narių, ir paprastai kiekvienas jų, priklausomai nuo savo atliekamų funkcijų, turi skirtingas naudojimosi intranetu teises. Magistrinio darbo tikslas - sukurti informacinę sistemą „Ei-tinklas“ gimnazijoje – intranetą – kaip vieną iš priemonių, skirtų šiuolaikinei vadybai bei mokymui(-si), realizuoti. / One of the most prevalent types of Internet Information Systems is Intranet. It is an organization network based on the collection TPC/IP of internet records. The main purpose of the Intranet is communication and cooperation among members of an organization, and usually each of them, depending on their accomplishing functions, has different rights of the Intranet’s usage. The aim of Master Degree Work is to create an information system “Ei-network” in the gymnasium – Intranet – as one of the means designed for implementing modern management and teaching (learning).
