The supramolecular chemistry of assemblies composed of a limited or infinite number of the molecular tectons interacting with each other via noncovalent interactions was investigated with a special emphasize on the chirality of the building blocks. The following objectives were pursued in this work: 1) to determine the electronic structure of both conformationally rigid and labile chiral bicyclo[3.3.1]nonane compounds, the mutual orientation and distance of the chromophores and its impact on chiroptical properties, 2) to study the influence of chirality and structure of palladacycle and trisubstituted compounds, containing external bicyclo[3.3.1]nonanyl- and aromatic fragments of different size on the formation of various supramolecular structures.
The chiral bicyclo[3.3.1]nonane compounds with chromophores of different electronic nature were synthesized. The possibilities of exciton interaction and charge transfer phenomena were studied in the obtained molecules. The influence of chirality and structure of trisubstituted compounds containing external bicyclo[3.3.1]nonanyl- and aromatic fragments of different size on supramolecular association in solution and on the surface was investigated. In solution, the trisubstituted compounds exist in the form of nanoparticles with regular supramolecular structure. It was shown that the V-shaped chiral and racemic dialkynbicyclo[3.3.1]nonenyl- ligands having coordinating pyridine moiety, form rhomb-shaped palladacycle. The racemic and...

Full textAbstract:
In this work, multinuclear solid-state nuclear magnetic resonance (NMR) spectroscopy is used to investigate a range of inorganic materials, often in combination with DFT (density functional theory) studies. Solid-state NMR is particularly suited to the study of aluminophosphates (AlPOs), as the basic components of their frameworks have NMR active isotopes (²⁷Al, ³¹P, ¹⁷O), as do many of the atoms that comprise the structure directing agent (¹³C, ¹H, ¹⁵N), and the charge-balancing anions (OH⁻, F⁻). A study of the AlPO STA-15 (St Andrews microporous solid-15) provides an introduction to using solid-state NMR spectroscopy to investigate AlPOs. More in-depth studies of AlPO STA-2 (St Andrews microporous solid-2) and MgAPO STA-2 (magnesium-substituted AlPO) examine charge-balancing mechanisms in AlPO-based materials. A range of scandium carboxylate metal-organic frameworks (MOFs), with rigid and flexible frameworks, have been characterised by multinuclear solid-state NMR spectroscopy (⁴⁵Sc, ¹³C and ¹H). The materials studied contain a variety of metal units and organic linkers. ¹³C and ¹H magic-angle spinning (MAS) NMR were used to study the organic linker molecules and ⁴⁵Sc MAS NMR was used to study the scandium environment in the MOFs Sc₂BDC₃ (BDC = 1,4-benzenedicarboxylate), MIL-53(Sc), MIL-88(Sc), MIL-100(Sc) and Sc-ABTC (ABTC = 3,3`,5,5`-azobenzenetetracarboxylate). Functionalised derivatives of Sc₂BDC₃ and MIL-53(Sc) were also studied. The ⁴⁵Sc MAS NMR spectra are found to be strongly dependant on the Sc³⁺ coordination environment. ²⁷Al and ²⁵Mg MAS NMR have been used to study Ti-bearing hibonite samples (of general formula Ca(Al, Ti, Mg)₁₂O₁₉), and results compared to a recent complementary neutron powder diffraction study, in order to investigate the substitution sites for Ti³⁺/⁴⁺ and Mg²⁺. A DFT investigation was also carried out on the aluminium end member, CaAl₁₂O₁₉, due to debate in the literature on the ²⁷Al NMR parameters for the trigonal-bipyramidal site. The substitution of Mg onto the tetrahedral site (M3) and Ti primarily onto one of the octahedral sites (M4) is supported.

Dans cette thèse, de nouvelles stratégies pour la préparation de matériaux de type Metal-Organic-Frameworks (MOF) ont été étudiés et développés. L’électrodeposition bipolaire indirecte (IBED) a été utilisé pour préparer ZIF-8 et HKUST-1 sur des substrats métalliques de façon simple et avec une sélectivité spatiale. Ce concept devrait pouvoir être généralisée pour la synthèse de nombreux autres composés MOF, permettant ainsi une synthèse pas chère et verte, conduisant à de nouvelles générations de composites de type Janus basés sur des MOFs. En outre, des électrodes avec une structure hiérarchique macro-/ microporeux de HKUST-1 ont été préparées par une technique de dissolution-dépôt électrochimique. L'approche de synthèse mis au point est très pratique en ce qui concerne la durée des expériences, et ouvre diverses applications pour les MOFs. Enfin des nanoparticules de métaux nobles sur un substrat à base de MIL-101 ont été préparées comme la dernière partie de l'étude expérimentale par dépôt colloïdal. Ce concept peut être généralisé pour la synthèse d'autres composites nanoparticules métalliques / MOF, et pourrait améliorer l'activité catalytique des MOFs. En dehors de l'étude expérimentale, afin de comprendre mieux la catalyse de matériaux MOF, le comportement catalytique de Cu (II) dans le MOF-505 a été théoriquement étudié pour la réaction d'aldolisation Mukayiama par la théorie de densité fonctionnelle et comparé à celui d'un autre catalyseur, Cu-ZSM-5. En outre, le comportement catalytique d'amas homo- et hétéro-bimétalliques, qui sont des complexes métalliques qui représentent les agrégats métalliques dans les MOFs, a également été étudié théoriquement pour la réaction de cycloaddition de dioxyde de carbone et des oxydes d'éthylèneIn this thesis, new strategies for the preparation of Metal 0rganic Frameworks (MOF) materials with designed structures were studied and developed. Indirect bipolar electrodeposition (IBED) was used to prepare ZIF-8 and HKUST-1 on metal substrates in a straightforward and site-selective way. This concept is expected to be able to be generalized for the synthesis of many other MOF compounds, thus allowing a cheap and green synthesis, leading to new generations of MOF-based Janus-type composites. Furthermore, rationally designed hierarchical macro-/microporous HKUST-1 electrodes were prepared via an electrochemical dissolution-deposition technique. The developed synthesis approach is very practical in terms of the time consumption, and opens up MOFs for various applications. Finally, MIL-101-supported noble metal nanoparticles were prepared as the last part of the experimental studies via a simple colloidal deposition technique. This concept might be generalized for the synthesis of other metal nanoparticle/MOF composites, and might improve the catalytic activity of MOFs. Apart from the experimental study, in order to gain a deeper insight into the catalysis of MOF materials, the catalytic behavior of Cu(II) in the paddle-wheel unit of MOF-505 was theoretically investigated for the Mukaiyama aldol reaction via the density functional theory and compared to that of another catalyst, Cu-ZSM-5 zeolite. Besides, the catalytic behavior of homo-metallic clusters and hetero-bimetallic clusters, that are the metal complexes representing the metal clusters in MOFs, were also theoretically investigated for the cycloaddition reaction of carbon dioxide and ethylene oxides

Full textAbstract:
Pour améliorer les performances des batteries au lithium, des ruptures technologiques sont nécessaires. Ceci impose que les aspects fondamentaux liés au fonctionnement de ces dispositifs électroniques soient reconsidérés. Dans cette optique, les méthodes de la chimie quantique peuvent apporter une aide précieuse, notamment pour comprendre les phénomènes électroniques microscopiques, à l'origine du stockage de l'énergie. Établir une relation directe entre la nature de la liaison chimique (microscopique) et les propriétés physico-chimiques (macroscopiques) des matériaux d'électrode pour batteries Li-Ion est donc l'objectif dans lequel s'inscrivent les travaux exposés dans cette thèse. Ce travail explore à la fois des aspects méthodologiques et des applications. Il vise à proposer des méthodologies d'analyse simples permettant de traiter les réactions électrochimiques d'un point de vue théorique et de déterminer les mécanismes microscopiques mis en jeu au cours des cycles de charge et de décharge des batteries. Les systèmes étudiés sont les composés d'insertion du graphite (Li-GICs) et un matériau hybride de type MOFs (« Metal Organic Framework ») basé sur l'ion ferrique (MIL-53(Fe)). Pour les Li-GICs, une nouvelle méthode couplant des calculs premiers principes DFT à un modèle statistique dérivé du modèle de Bethe-Peierls a été développée pour rendre compte des effets d'entropie (de configuration) dans leur diagramme de phase. Les résultats obtenus apportent un nouveau regard sur les processus électrochimiques induits par le lithium, ouvrant des perspectives technologiques intéressantes pour remédier aux problèmes de sécurité posés par ce type d'électrode. Pour le MIL-53(Fe), la méthode DFT+U a été utilisée pour rendre compte des effets de corrélation électronique et pour reproduire l'état fondamental complexe de ce système. Les résultats obtenus ont permis de comprendre l'origine de la faible capacité de ce matériau vis-`a-vis du lithium.

Full textAbstract:
Les zéolites, aluminosilicates cristallisés microporeux, sont largement utilisés en raffinage, en pétrochimie et en conversion de la biomasse. En raison du faible diamètre des micropores, limitations diffusionnelles et effets de confinement peuvent favoriser la formation de sous-Produits non désirés. L'introduction de mésopores par désalumination et/ou désilication ("zéolites hiérarchisées") peut diminuer ces phénomènes. Cependant, les mécanismes ces réactions restent méconnus à l'échelle moléculaire. Par calculs quantiques périodiques, au niveau de la théorie de la fonctionnelle de la densité (DFT) et selon une approche hybride QM/QM, nous avons pu mettre en évidence l'importance de l'attaque de la molécule d'eau sur l'atome d'aluminium, qui se fait en anti par rapport au site acide de Brønsted. Des structures d'Al penta ou tetra coordinées ont aussi été suggérées expérimentalement comme précurseurs de la désalumination. Malgré une forte hétérogénéité structurale des sites T, l'élucidation des chemins réactionnels et les énergies d’activation des étapes d’hydrolyse des liaisons Al-O (70-100 kJ/mol) dans les systèmes zéolitiques investigués (MOR, FAU, MFI, CHA) nous a permis d'établir des corrélations du type Brønsted-Evans-Polanyi. Ces corrélations permettent d'estimer et prédire des énergies d'activation par le biais de la thermodynamique, donne ainsi une prédiction aisée des sites T sensibles à la désalumination. Un autre facteur clé pour la compréhension de la désalumination est l'effet de confinement sur l'espèce aluminique extra-Réseau générée (EFAL), exercé par les cavités. Finalement nous avons pu montrer que le chemin réactionnel de désalumination et désilication, consécutif ou simultané, , est thermodynamiquement plus favorable qu'une simple désalumination ce qui est en accord avec les propositions mécanistiques de la littérature sur la genèse de mésopores par démétallationZeolites are crystalline microporous aluminosilicates widely used in refining, petrochemistry and biomass conversion. However, diffusion limitation and confinement effect can promote the formation of undesired products. The introduction of mesopores by dealumination and/or desilication ("hierarchical zeolites") is a possible solution widely used experimentally. Nevertheless, the mechanisms of these demetallation reactions are poorly described at the molecular scale. We determine the mechanisms of the formation of extraframework Al species (EFAL) for zeotypes MOR, FAU, MFI and CHA occurring during the dealumination process, possibly associated with desilication. First-Principles periodic density functional theory (DFT) and hybrid QM/QM calculations have been employed in order to analyze full reaction paths leading to extraframework species and to quantify the activation energies of the determining steps. It has been demonstrated that the initiation of an Al-O(H) bond break takes place via water adsorption on the Al atom in anti-Position to the Brønsted acid site, via a penta- or tetra-Coordinated Al species. Such species are shown to be at the initiation of the Al dislodgement from the zeolitic framework. Despite a strong structural heterogeneity of T sites, we determined Brønsted-Evans-Polanyi (BEP) relationships for the entire dealumination pathway. Moreover, it is shown that not only the initiation and propagation mechanisms are primordial for the understanding of an Al extraction, but also the confinement effect on EFAL species within the zeolites cavities. Finally, from the energy profile of combined dealumination/desilication pathways, we show that it is thermodynamically favoured to extract extraframework Si species (EFSI) in the course of dealumination

Full textAbstract:
Ce travail théorique vise à étudier, via les méthodes Premiers Principes, les propriétés des complexes de métaux de transitions, left[Mleft(dmbpyright)_{3}right]^{n+}nCi^{-} pour un usage en batterie. Pour cette étude ab-initio, les composés mono et bi-nucléaires ont été retenus. La pertinance de notre modélisation a été validée sur les composés mononucléaires. Nous nous sommes interessé au complexes de Fe, Ru et Cu pour lesquels une validation expérimentale était possible. Notre étude a principalement consisté à faire varier les degrés de liberté que nous possédons pour optimiser le voltage et la cinétique de chargement des batteries. Pour cela, nous avons fait varier le TM = Fe, Ru, et Cu, la nature des contre-ions Ci^{-}=PF_{6}^{-}, TFSI^{-} et ClO_{4}^{-} en interaction avec le polymère lors du processus de charge, ainsi que la longeur de la chaîne alkyl qui sépare les deux monomers dans le cas des composés binucléaires. Le composé à base de Fe avec une chaîne -left(CH_{2}right)_{n=6}- a été retenu comme le meilleur candidat pour une application batterie. Le composé à base Ru montre un comportement proche de celui du Fe, quant-au complexe de Cu, il présente des changements de géométrie locale sous chargement trop importants, le rendant peu apte à conduire à une cinétique efficace. Cette étude nous a permis de déterminer que l'approximation PBE était le meilleur choix possible pour modéliser nos complexes dans les conditions de fonctionnement en batterie (dans le champ créé par les contre-ions) et que l'approximation PBE0, généralement utilisée dans la littérature, ne pouvait rendre compte de la physico-chimie de nos composés dans de telles conditions.De surcroît, nous avons dévelopé pour le complexe de Fe, un potentiel atomistique de type “Champ de forces” de manière à pouvoir aborder les aspects dynamiques impliquant de plus grandes tailles de boîte de simulation. Ici, nous modélisons une structure 3D, totalement réticulée à partir de nos monomères à base de Fe. Nous nous sommes servi de la base de donnés DFT que nous avions généré (énergies, géométries, état de spin et fréquences vibrationnelles calculées) pour ajuster les paramètres entrant dans l'écriture du modèle. La construction de la géométrie initiale du polymère 3D a nécessité l'écriture d'un code de calcul visant à produire un arrangement complétement réticulé et à assigner les charges effectives issues des calculs DFT. Ce modèle nous a permis de déterminer les coefficients de diffusion des contre-ions pour les états totalement chargé et non-chargé. Un calcul plus ambitieux vise à déterminer les chemins de diffusion des contre-ions lors d'un processus de chargement en considérant un seul centre de degré d'oxydation 3+ au centre du polymère 3D, pour lequel les centres actifs possèdent un degré d'oxidation 2+. Les contre-ions assurent la neutralité globale.Keyword: Polymer, Electrochemistry, Li-ion Battery, DFT, Force Field development, 3D structure, Atomistic modelingAbstract Standard redox potentials for mono and bi-nuclear transition metal (TM) complexes left[Mleft(dmbpyright)_{3}right]^{n+}nCi^{-}, have been investigated using First Principles Calculation. Three metal centers are investigated: Fe, Ru, and Cu. Our modeling is validated on mono-nuclear compounds. This approach consists in determining the best small polymer (bi-nuclear) made out of these monomers for a battery application. For that, we varied the three available degrees of freedom i.e., the nature of the central TM atom (Fe, Ru, and Cu), counter-ions Ci=PF_{6}^{-}, TFSI^{-} and ClO_{4}^{-} in interaction with the polymer, and the alkyl chain -left(CH_{2}right)_{n}- of length n that connects both mono-nuclear in the bi-nuclear compound. The Iron compound with -left(CH_{2}right)_{n=6}- is found to be the best candidate. The left[Culeft(dmbpyright)_{2}right]^{n+}nCi^{-} complex shows too much structure deformation upon loading, making it less reliable for cathode material. Moreover, we studied two XC functional, PBE and PBE0 and found, for three complexes PBE approximation retains the ligand field picture whereas PBE0 functional induces an exaggerated and unexpected band dispersion by dissolving the ligand field picture expected for the octahedral environment of the TM in the studied complexes. These findings validate that hybrid functional for which it was designed to localize and cancel self-interaction error does not work for all system. More particularly, the PBE0 approximation fails to model the three complexes (Fe, Ru, and Cu) in functional conditions (in the field made by the counter-ions).Abstract Further, we have developed an atomistic potential relying on the Force Field scheme for the Iron complex in order to study the dynamical properties of this compound at larger simulation scale (3D reticulated polymerization made of our Fe complex monomers). We made an intensive use of our DFT data (energies, geometries, spin-state configurations and calculated vibrational properties) to develop the required parameters entering the model. Moreover, computational techniques (written python language) were developed specifically to create a 3D structure of transition metal complexes satisfying the condition to be fully reticulated. Bounding conditions had to be designed and a procedure aiming at fixing reliable and physical effective charges on each atom of the simulation cell (compatible with DFT results) were developed. Our first simulations have been attached to calculate the diffusion coefficients of the counter-ions in both the fully loaded and unloaded states. A more ambitious and realistic calculation aims at investigating the paths of the counter-ions when one single center starts to be loaded in an unloaded environment.Abstract Keyword: Polymer, Electrochemistry, Li-ion Battery, DFT, Force Field development, 3D structure, Atomistic modeling

As redes metalorgânicas (ou MOF, do inglês Metal-Organic Frameworks) pertencem à classe dos polímeros de coordenação (ou CP, do inglês coordination polymers) e exibem características como porosidade e cristalinidade. Em particular, as MOF bidimensionais têm despertado o interesse no desenvolvimento de uma nova geração de dispositivos ópticos e eletrônicos. A capacidade de formação de filmes finos de algumas dessas MOF as tornam materiais mais atraentes. A MOF bidimensional estudada neste trabalho foi a rede {[Zn(2,5-pdc)(H2O)2].H2O}n (2,5-pdc = 2,5-piridinodicarboxilato), ZnPDC2D. A MOF 2D foi sintetizada e caracterizada por diferentes técnicas experimentais e também foi estudada por simulação computacional. O modelo do ZnPDC2D foi otimizado por dois métodos (PBE e PBE-D2), os quais descreveram bem os parâmetros estruturais. A partir do modelo do ZnPDC2D, foi elaborada uma proposta para o processo de desidratação e assim, sugerindo a formação de três novas fases (d1-ZnPDC2D, d2-ZnPDC2D e d3-ZnPDC2D). A temperatura em que o ZnPDC2D sofre amorfização foi determinada através da medida de difração de raios X com aumento de temperatura in situ e pôdese inferir que a fase amorfa sofre uma transformação reversível após ser exposta ao ambiente. A termodinâmica da primeira etapa da desidratação mostra que o funcional PBE é mais adequado para descrever a espontaneidade da reação. Esperase obter as estruturas por meio de análises de difração de raios X por policritais e refinamento pelo método de Rietveld. O trabalho também reporta a simulação da energia de formação do monofilme pelos métodos PBE e PBE-D2. As análises de propriedades eletrônicas para todas as estruturas citadas foram executadas e discutidas conforme os processos e mudanças envolvidas.
Metal-organic frameworks (MOFs) belong to the class of coordination polymers (CPs) and exhibit properties such as porosity and crystallinity. In particular, twodimensional MOFs have attracted interest in the development of a new generation of optical and electronic devices. The possibility of thin film formation of some of these MOFs makes them more attractive materials. The twodimensional MOF studied in this work was the network {[Zn(2,5-pdc)(H2O)2].H2O}n (2,5-pdc = 2,5-pyridinedicarboxylate), ZnPDC2D. The MOF 2D was synthesized and characterized by different experimental techniques and was also studied by computer simulation. Two optimized ZnPDC2D structures were obtained by distinct methods (PBE and PBE-D2) with a good description of their parameters. The structure obtained from the simulation of the dehydration process suggest the formation of three new phases (d1-ZnPDC2D, d2-ZnPDC2D and d3-ZnPDC2D). The temperature at which ZnPDC2D undergoes amorphization was determined by Xray podwer diffraction measurement with in situ temperature rise and it could be inferred that the amorphous phase undergoes a reversible transformation after being exposed to the environment. The thermodynamics of the first stage of dehydration shows that the PBE functional is adequate to describe the spontaneity of the reaction. The structures are expected to be obtained by Xray podwer diffraction analysis and refinement by the Rietveld method. Thise work also reports the simulation of the monofilm by the PBE and PBE-D2 methods. The analyses of electronic properties for all th cited structures were performed and discussed according to the processes and changes involved.

Full textAbstract:
Dans cette étude, nous proposons des procédures basées sur des calculs informatiques et des modèles théoriques qui peuvent être utilisés pour prévoir le comportement de certains matériaux membranaires d'intérêt pour les applications de séparation de gaz. En particulier, nous nous sommes concentrés sur: i) des alliages VNiTi de structure cubique centrée, considérés comme de nouveaux matériaux pour les membranes denses sélectives à H2 et ii) sur des matériaux poreux cristallins qui sont des systèmes attractifs pour la séparation de gaz légers tels que H2, O2, CO, CO2, CH4 et N2. Les deux groupes de matériaux sont traités en utilisant une méthodologie différente, adaptée aux besoins des recherches associées à ces matériaux.Dans le cas des membranes métalliques denses, nous nous sommes intéressés à la controverse, connue de longue date, concernant l'occupation de l'hydrogène interstitiel dans les alliages à base de vanadium. Le système V-Ni-Ti est en effet particulièrement intéressant grâce à sa perméabilité élevée pour H2 et à ses propriétés mécaniques accrues par rapport au vanadium pur. Ce travail cible la compréhension de la structure ces alliages à l'échelle atomique, de façon à les optimiser et à activer la conception et le développement de ces matériaux comme nouvelles membranes pour la séparation de H2. Notre approche, basées sur les premiers principes, donne un aperçu des sites préférentiels de l'hydrogène et évalue le rôle des solutés de substitution Ti et Ni, sur l'affinité d'absorption de l'hydrogène. La méthode basée sur la théorie de la fonctionnelle de la densité (DFT) ne nécessite aucune donnée expérimentale autre que l'information sur la structure cristalline. En outre, cette méthode n’utilise aucun paramètre empirique ou d’ajustement, contrairement à d'autres techniques de calcul. Ainsi, cette approche est une voie alternative pour explorer de nouveaux alliages métalliques utilisables comme membranes de séparation de H2. La méthodologie appliquée pourra être utilisé ensuite dans des calculs à haut débit pour cribler diverses compositions d'alliage. Les résultats reportés ici seront utilisés comme guide pour adapter la formulation des solutions solides VNiTi et préparer des membranes en alliage denses à faible coût (par rapport aux membranes à base de palladium) dans le cadre d’autres projets (e.g. Projet Européen FP7- DEMCAMER).Dans le cadre de notre étude sur les membranes cristallines microporeuses, nous démontrons comment les données sur un composant unique peuvent être utilisées pour prédire la sélectivité idéale de ces membranes envers les gaz légers. Des modèles théoriques sont ainsi proposés pour décrire les propriétés de séparation de gaz de matériaux de type zéolithiques (« zeotypes ») en fonction de leurs paramètres structuraux et des conditions de fonctionnement. Les paramètres du modèle peuvent être obtenus expérimentalement ainsi que par le calcul. Afin d’analyser le degré de validité et les limites des modèles, les sélectivités idéales de deux membranes zéolithes classiquement étudiées (NaA, CaA) et d’une membrane MOF (ZIF-8) ont été évaluées. Les résultats démontrent que les expressions théoriques peuvent être utilisées pour le criblage de séries de matériaux microporeux cristallins sous réserve que des données fiables sur l'adsorption de gaz purs soient disponibles pour ces matériaux. Cependant, étant donné que les modèles n’intègrent pas tous les paramètres (notamment liés au design des membranes) et mécanismes impliqués dans le transport de gaz à travers ces membranes, les prédictions doivent être considérées comme celles correspondant à un cas idéalIn this study, we propose procedures based on computational calculations and theoretical models that can be used to predict the behaviour of some of the membrane materials of interest for gas separation applications. In particular, we focus on: i) body-centred cubic VNiTi alloys as novel materials for H2-selective dense membranes and ii) crystalline porous materials that are attractive media for separation of light gases such as H2, O2, CO, CO2, CH4 and N2. These two types of materials are treated using different methodologies, adapted to the needs of our research objectives associated to each material.In the case of dense metal membranes, the long-standing controversy over occupancy of interstitial hydrogen in V-based alloys is addressed. The V-Ni-Ti system is of particular interest here, exhibiting high H2 permeability and improved mechanical properties relative to pure V. This work intends to gain understanding of hydrogen-metal interactions as function of alloy composition and thereby to optimize these new materials and advance their development as novel membranes for H2 separation. We use a first-principles approach that gives insights into the sites preference of hydrogen and assesses the role of Ti and Ni substitutional solutes for the hydrogen absorption affinity. The method based on Density Functional Theory requires no experimental input except crystal structure information. Furthermore, it uses no empirical or fitting parameters in contrast to other computational techniques. Hence this approach provides an alternative way to explore new metal alloys for H2 separation membranes. The applied methodology can be used further in high-throughput calculations to screen various alloy compositions. The hereto-reported results will be used as guidance for tailoring the formulation of VNiTi solid solutions and preparation of low cost dense alloy membranes in the frame of other projects (e.g. European DEMCAMER project).Further, we explore how single-component inputs can be used to forecast the ideal selectivity towards light gases of crystalline porous materials, used for membrane preparation. Theoretical models for describing gas separation properties of zeotype materials as function of structural characteristics and operation conditions are proposed. The model parameters can be obtained as experimentally as well as computationally. To analyse the extent of validity and limitations of the models, ideal selectivities of few crystalline porous materials are evaluated, including widely used zeolites (NaA, CaA) and a metal organic framework structure (ZIF-8). The results verified that the theoretical expressions could be used for screening series of zeotype materials when reliable single gas adsorption data are available. However, since the models don’t take into account all parameters (namely related to the membrane design) and mechanisms involved in gas transport through porous membranes, their predictions should be considered as values referring to an ideal case

Full textAbstract:
Malgré de nombreux efforts en faveur de l'utilisation des énergies renouvelables, les combustibles fossiles continuent de dominer la production énergétique mondiale, ce qui entraîne des émissions importantes de gaz à effet de serre dans l'atmosphère.L'utilisation d'adsorbants solides très poreux et chimiquement accordables, tels que les cadres métallo-organiques (MOF), a suscité beaucoup d'intérêt au cours des 20 dernières années en raison de leur application potentielle dans les technologies de séparation des gaz et de capture du carbone. Dans ce travail, nous proposons de concevoir par calcul des MOFs dont la haute affinité pour les molécules invitées peut être modifiée par traitement thermique. Avec un choix approprié de ligands et de centres métalliques, les MOF présentant un croisement de spin induit thermiquement (SCO) et un changement concomitant des propriétés d'adsorption peuvent être développés pour éventuellement produire une capture et une libération de gaz plus efficaces sur le plan énergétique.D'un point de vue informatique, le défi de la simulation du phénomène de SCO en utilisant des méthodes de structure électronique ab initio est représenté par l'évaluation de la thermodynamique du SCO. Pour résoudre ce problème, nous développons un schéma basé sur la DFT+U pour obtenir une description précise des différences d'énergie à l'état de spin dans les complexes de Fe(II). Une évaluation critique de l'approche Hubbard U dans la description de l'énergie à l'état de spin est présentée et les résultats de cette analyse sont utilisés pour proposer une manière pratique et efficace de les surmonter. Cette approche, qui est testée et validée par rapport aux expériences et aux résultats de CASPT2/CC, est ensuite utilisée pour proposer la preuve de concept in silico du SCO-MOF induit par la température pour une libération efficace du gazThe use of highly porous, chemically tunable solid adsorbents such as metal-organic frameworks (MOFs) has attracted much interest in the past 20 years for their potential application in gas separation and carbon capture technologies. In this work, we propose to computationally design MOFs whose high affinity for guest molecules can be modified under temperature treatment. With a suitable choice of ligands and metal centers, MOFs exhibiting a thermally-induced spin crossover (SCO) and a concomitant change in the adsorption properties can be developed to possibly yield more energy-efficient gas capture-and-release.From a computational point of view, the challenge in simulating the SCO phenomenon using textit{ab initio} electronic structure methods is represented by the evaluation of the thermodynamics of SCO. To address this issue, we develop a DFT+U-based scheme to achieve an accurate description of spin-state energy differences in Fe(II) complexes. A critical assessment of the Hubbard U approach in the description of spin-state energetics is presented and insights from this analysis are used to propose a practical and efficient way to overcome them. This approach, which is tested and validated against experiments and coupled cluster-corrected CASPT2 results, is then used to propose the proof-of-concept in silico of temperature-induced SCO-MOF for efficient gas release

Full textAbstract:
Problem: The process planning task for a given design problem in additive manufacturing can be greatly enhanced by referencing previously developed process plans. However, identifying appropriate process plans for the given design problem requires appropriate mapping between the design domain and the process planning domain. Hence, the objective of this research is to establish mathematical mapping between the design domain and the process planning domain such that the previously developed appropriate process plans can be identified for the given design task. Further more, identification of an appropriate mathematical theory that enables computational mapping between the two domains is of interest. Through such computational mapping, previously developed process plans are expected to be shared in a distributed environment using an open repository.
Approach: The design requirements and process plans are discretized using empirical models that compute exact values of process variables for the given design requirements. Through this discretization, subsumption relations among the discretized design requirements and process plans are identified. Appropriate process plans for a given design requirement are identified by subsumption relations in the design requirements. Also, the design requirements that can be satisfied by the given process plans are identified by subsumption relations among the process plans. To computationally realize such mapping, a description logic (ALE) is identified and justified to represent and compute subsumption relation. Based on this investigation, a retrieval method (DFM framework) is realized that enables storage and retrieval of process plans.
Validation: Theoretical and empirical validations are performed using the validation square method. For the theoretical validation, an appropriate description logic (ALE) is identified and justified. Also, subsumption utilization in mapping two domains and realizing the DFM framework is justified. For the empirical validation, the storing and retrieval performance of the DFM framework is tested to demonstrate its theoretical validity.
Contribution: In this research, two areas of contributions are
identified: DFM and engineering information management. In DFM, the retrieval method that relates the design problem to appropriate process plans through mathematical mapping between design and process planning domain is the major contribution. In engineering information management, the major contributions are the development of information models and the identification of their characteristics. Based on this investigation, an appropriate description logic (ALE) is selected and justified. Also, corresponding computational feasibility (non deterministic polynomial time) of subsumption is identified.

Full textAbstract:
Gamification har börjat integreras mer och mer i våra liv varje år inom diverse områden såsom shopping, sport och undervisning. Gamification används per definition för att öka motivation hos användare genom att introducera spelmoment i en icke-spel kontext. Denna studie syftar till att utvärdera hur bra de designprinciper och designriktlinjer, som är formade utifrån ett ramverk som kallas för MDA-ramverket (ett ramverk inom gamification), kan tillämpas vid utformningen av en gamificationapplikation inom kontexten av ett biobesök eller om det krävs en modifiering av dessa. Studien syftar även till att ta reda på huruvida den här typen av applikation skulle kunna öka det generella intresset för att bli medlem hos en bioverksamhet likt Filmstaden. För att ta reda på detta gjordes en intervju som en del av förstudien för att kontrollera den generella attityden och intresset för en applikation som denna. MDA-ramverket användes sedan till att utveckla en Lo-Fi prototyp utifrån principerna och riktlinjerna inom MDA-ramverket. Denna prototyp testades genom att observera totalt tio användare som fick interagera fritt med prototypens olika funktioner. Observationen följdes upp av en intervju med samma användare som fick uttrycka sina känslor gentemot applikationen och de potentiella problem som uppkom med den. Analysen av observationen samt svaren från respondenterna jämfördes sedan med principerna och riktlinjerna som användes under designfasen för att se hur väl dessa kunde tillämpas i kontexten av ett biobesök eller om de kunde ses som felaktiga. Resultatet av studien visade på att de flesta riktlinjer var essentiella för kvalitén av prototypen men att några av dem borde ses över vid utvecklingen av en gamificationapplikation i kontexten av ett biobesök. Slutligen visade också studien, baserat på intervjusvaren som samlades in, att en applikation som denna skulle kunna öka motivation bland biobesökare att bli medlem i Filmstadens bioklubb.Gamification has been increasingly integrated into our lives every year within different areas such as shopping, sports and education. It focuses by definition on increasing the motivation in users by introducing gaming elements into a non-gaming context. This paper aims to investigate how well current design principles and design guidelines, that have been shaped from the so-called MDA-framework (a framework within gamification), can be used for designing a gamification application within the context of a cinematic experience or if modification is required. It also investigates whether this sort of application would be able to increase the general interest of becoming a member at a cinema enterprise such as Filmstaden, Sweden. First of all, an interview was constructed as part of the pre-study to check the general attitude and interest toward an application like this. An existing framework for gamification called the MDA-framework was then used to create a Lo-Fi prototype that practices the principles and guidelines of MDA for an optimal design. This prototype was then tested by observing a total of 10 users who got to interact freely with the different functions. This observation was followed by an interview with the same users where they got to express their feelings toward the application and the potential issues that were presented with it. This result was then compared to the principles and guidelines used during the design to see whether any of the guidelines could be seen as faulty or if any potential guidelines were missing. The analysis of the research showed that most principles and guidelines were very helpful and brought the quality of the prototype to a satisfactory level on most accounts. The attitude towards some of the guidelines was proven to have changed since their emergence though. Finally, the paper also discovered, based on the applicant’s answers, that an application like this could increase the motivation of becoming a member in the “Cinema Club”.

Full textAbstract:
When stress-related diseases are increasing, the preventive work becomes increasingly important. The aim with this essay is to determine established law about psychosocial working environment. With the legal dogmatic method, an investigation has been made about the law on working conditions and what it says about preventive work to the psychosocial working environment. After a profound investigation regarding the frameworks pros and cons, it is possible to draw the conclusion that the law on working environment should keep the character of framework. Even if this entails difficulties with interpretation, it is not suitable to regulate the details in a law that should be appropriate for every profession. By studying the regulations of Swedish Work Environment Authority, the law is clarified. However, they should also clarify the concepts, which the law refers to, in order to know when the law should be applied. The same problem occurs when an analysis is made of the declaration forms of accidents and incidents. As a consequence of a weakly formulated definition of “serious incident”, problems arise when applying the law. How stress-related incidents should be treated is also weakly formulated, which could complicate and delay the preventive work. This is because the employers only know that they should report the diseases but not the incidents.

Full textAbstract:
Med målet att uppnå vattenkvalité av god status inom hela EU införde Europaparlamentet år 2000 ramdirektivet för vatten (2000/60/EC), även kallat Vattendirektivet. För att uppnå god vattenstatus sätts mål i form av ”miljökvalitetsnormer”(MKN) på vattendrag, sjöar, kustvatten och grundvatten inom varje län och kommun. Dessa ska beaktas vid framtagandet av nya detaljplaner vilket är ett juridiskt gällande dokument där den tillåtna exploateringen av ett område fastställs. I detaljplanen ska planens påverkan på möjligheterna att uppnå MKN för vatten utredas och presenteras. Det saknas dock tydliga riktlinjer för hur denna bedömning ska göras och vilka aspekter som ska ingå i utredningen. I de fall planen medför att målen i form av MKN riskeras att inte uppnås är det länsstyrelsens uppgift att hindra planen från att godkännas. Syftet med studien är att utreda vad som är viktigt i arbetet att ta fram en detaljplan som beaktar MKN för vatten och hur kommuner och länsstyrelser upplever arbetet. Målet är att undersöka det övergripande arbetet och därefter fokusera på den bedömning som görs av vilken påverkan på MKN en plan medför. Detta för att ge en bild av hur arbetet sker i dagsläget och belysa de utmaningar och förbättringsmöjligheter som finns. Studien avgränsas geografisk till länsstyrelserna inom Norra Östersjöns vattendistrikt och kommunerna i Stockholms län. För att undersöka det ovannämnda genomfördes en förstudie bestående av en intervjustudie riktad till konsulter och anställda på kommun och länsstyrelser, och en litteraturstudie. Förstudien ledde fram till formuleringen av frågor i enkätstudien. Enkätstudien bestod av två delar där den första riktade sig till kommuner i Stockholms län och den andra till länsstyrelserna i Norra Östersjöns vattendistrikt. Resultatet från studien bidrog till att identifiera viktiga steg i processen att ta fram en detaljplan som följer satta MKN. Även svårigheter kopplade till de olika processtegen framkom. Uppföljning visade sig vara ett steg som inte genomförs i så stor utsträckning men som troligtvis kan förbättra situationen genom att bidra med data och kvalitetssäkring av metodiken. Bedömningen som görs av hur en plan påverkar möjligheten att uppfylla MKN sammanställdes i några nyckelsteg. De flesta svårigheter som upplevs av de kommunanställda är kopplade till att utföra den här bedömningen. Främst är det osäkerheter i metod och modelleringsverktyg tillsammans med ofullständigt underlagsmaterial som bidrar till svårigheterna. Det preliminära åtgärdsprogram som presenterats våren 2016 av Vattenmyndigheten inför nästa 6-åriga arbetscykel bidrar förhoppningsvis med att vägledningsmaterial och tydligare riktlinjer tas fram. Detta efterfrågades från flera håll i enkätstudien. Förutom det som åtgärdsprogrammet adresserar ses ett behov av mer utbildning och samverkan av och mellan aktörer. Beräkningsmetoder och underlag som används behöver även ses över och det behöver finnas en tydligare samsyn på hur en detaljplansplans påverkan på MKN ska bestämmas.With the goal of high quality recipients within the European Union the European Water Framework Directive (WFD; 2000/60/EC) was initiated in the year of 2000. In order to achieve water of high quality, goals have been established under the definition of Environmental Quality Standards (EQS). These are defined for lakes, rivers and other water bodies within each municipality. The EQS are defined as a level that are to be reached until a defined year. The EQS are to be kept in mind when zoning is carried out within a municipality. Zoning allows for strategic use of land and water within the municipality and is an important part in the work of achieving the EQS. If a zoning plan does not meet the EQS the plan should not be adopted. The county government should audit plans before they are approved to make sure the chance of reaching the EQS are not hindered by the plan. The aim of this study is to investigate which important factors that come into play when a zoning plan is created that will meet the EQS. The aim is also to get an understanding of the work from the municipalities perspective as well as from the viewpoint of the county government. Both the overall perspective and the more detailed field of assessing the impact from a zoning plan is to be analyzed. In the end the goal is to give an overview of how the work is done today, which difficulties that are experienced as well as improvements that could be needed. The study is focused upon the county governments within the North Baltic Sea basin and the municipalities within Stockholm county. Semi-structured interviews and a literature review were conducted followed by a survey study in order to address the research questions. The survey study was directed towards the county governments and municipalities within the geographical study area mentioned above. From the methods described above data was collected which resulted in the identification of important steps in the process of making zoning with consideration of the EQS. Also difficulties connected to each phase were identified. The work of follow-up and monitoring was found only to be carried out to a limited extent but is believed to support several important functions in the work, if improved. The impact assessment of zoning on water quality and EQS was found to be one of the more difficult parts of the work with the WFD. Foremost, this process is connected to many uncertainties in the method of calculation but also due to limited data available in some cases. Information needed is for example the current water quality and the levels of pollution connected to different land uses of the area. More developed guidelines and support from central authorities was requested by several participants of the survey. Hopefully the Water authorities’ planned action program for the next 6-year work cycle, will result in this. However, more investigations and studies are needed in order to improve and minimize uncertainties in the methods used to calculate impact from zoning on water quality. More education and cooperation between municipalities, county governments and agencies with issues connected to implementing the WFD is needed as well. Overall more consensus is needed in how the work can be carried out while meeting both environmental and societal goals.

Full textAbstract:
Purpose – The purpose of this report is to find out which frameworks and methods are most popular and most widely used, as well as web developers' views on the hamburgermenu. Method – In order to answer the questions in our report we used the methods quantitative statistical processing, quantitative analysis of data collected via survey and qualitative interviews with web developers. The study was conducted to find out which frameworks and methods are most popular and used most, as well as how web developers look at the hamburgermenu. This was done by analyzing the popularity and usage of different frameworks as well as interviewing web developers who work with it daily. Findings – The results of the report are based on the data collected through the processing of the statistics, the analysis of the survey, and the interviews performed. The result shows which frameworks are most popular and those that are most used. The following list shows the ranking: Most popular: Bootstrap Semantic UI Materialize Material Design Lite Foundation Most used: Bootstrap Foundation Materialize Material Design Lite Semantic UI The results of the interviews showed that most of the web developers interviewed used a framework when they created a website, either an existing or one of their own. It was also a practice to use the same framework in the company, although the way it was used was different from developer to developer. All developers had a mobile-first thought in mind, although it was not always a priority. It was also found in the study that everyone had a basic idea behind the choice of framework, but only one who had performed a study on which one would suit them best. All web developers interviewed thought that the hamburger menu was boring and bad from a user experience perspective. But everyone also agreed that because it is so widely used and has been for a couple of years, users have learned what it means and therefore fulfills its purpose. Implications – The use of the results is primarily linked to individuals or companies that work with web development, but can also be used by private individuals. For the report's primary target group, the results will give an increased understanding of the most used framework and an increased understanding of why these are used. Private individuals can use the result in the same way. Limitations – The limitations we receive in this study are that we cannot make any conclusions about companies and web developers in other parts of the country using the same framework or methods as the local ones we interviewed. Nor can we make any conclusions about why Bootstrap is the most popular and most widely used framework. We can only speculate why with the empirical we gathered through the interviews. A major limitation is also the lack of interviews when we only got answers from 6 of the 10 companies we contacted, of whom 4 would like to participate in the interview. More general conclusions could have been drawn if more companies had been interviewed. Keywords – Framework, Web Development, Responsive Web Design, Interaction Design, User Experience, Bootstrap, Foundation, Materialize, Material Design Lite, Semantic UISyfte – Syftet med denna rapport är att ta reda på vilka ramverk och metoder som är populärast och mest använda, samt webbutvecklares syn på hamburgermenyn. Metod – För att besvara frågeställningarna används metoderna kvantitativ bearbetning av statistik, kvantitativ analys av data insamlad via survey samt kvalitativa intervjuer med webbutvecklare. Studien genomfördes för att ta reda på vilka ramverk och metoder som är populärast och används mest, samt hur webbutvecklare ser på hamburgermenyn. Detta gjordes genom att analysera olika ramverks popularitet och användande samt att intervjua webbutvecklare som arbetar med det dagligen. Resultat – Rapportens resultat är baserat på den data som samlats in genom bearbetningen av statistiken, analysen av survey, samt de intervjuer som utfördes. Resultatet visar vilka ramverk som är populärast samt vilka som används mest. Följande lista visar rangordningen: Populärast: Bootstrap Semantic UI Materialize Material Design Lite Foundation Mest använt: Bootstrap Foundation Materialize Material Design Lite Semantic UI Resultatet av intervjuerna visade att majoriteten av de webbutvecklare som intervjuades använde ett ramverk när de skapade en hemsida, antingen ett existerande eller ett eget skapat. Det var också praxis att använda samma ramverk i företaget, även om sättet man arbetade med det kunde skilja sig från utvecklare till utvecklare. Samtliga utvecklare hade ett mobile-first tänk i åtanke, även om det inte alltid prioriterades. Det framgick även i studien att samtliga hade en grundtanke bakom valet av ramverk, men det var endast en som faktiskt hade utfört en undersökning om vilket som skulle passa dem bäst. Samtliga webbutvecklare som intervjuades tyckte att hamburgermenyn var tråkig och dålig ur ett användarupplevelseperspektiv. Men samtliga tyckte även att eftersom den används så brett och har gjort i ett par år så har användare lärt sig vad den innebär och fyller därför sitt syfte. Implikationer – Resultatets användningsområden är främst kopplade till personer eller företag som arbetar med webbutveckling men kommer även att kunna användas av privatpersoner. För rapportens primära målgrupp kommer resultatet att ge en ökad förståelse för vilka ramverk som används mest samt en ökad förståelse för varför dessa används. Privatpersoner kan använda resultatet på samma sätt. Begränsningar – Begränsningarna som vi får i denna studie är att vi inte kan dra några slutsatser om företag och webbutvecklare i andra delar av landet använder sig av samma ramverk eller metoder som de lokala vi intervjuat. Vi kan heller inte dra några slutsatser om varför Bootstrap är det mest populära och mest använda ramverket. Vi kan endast spekulera om varför med hjälp av den empiri vi samlat in via intervjuerna. En stor begränsning är även bristen av intervjuer då vi endast fick kontakt med 6 av de 10 företag som vi kontaktade, varav 4 stycken ville ställa upp på att delta i intervju. Fler generella slutsatser hade kunnat dras om fler företag hade ställt upp på intervjuer. Nyckelord – Ramverk, Webbutveckling, Responsiv webbdesign, Interaktionsdesign, Användarupplevelse, Bootstrap, Foundation, Materialize, Material Design Lite, Semantic UI

Full textAbstract:
Idag står vi inför flera miljöproblem som exempelvis klimatpåverkan och förlust av biologisk mångfald. Vattenkraften är en förnybar energikälla som kan producera el med låga utsläpp av växthusgaser. Sverige har en lång tradition av att utnyttja vattnet som energikälla och har det senaste århundradet byggt ut en majoritet av de svenska vattendragen med vattenkraftverk. Idag står vattenkraften för nästan hälften av Sveriges elproduktion och bidrar till Sveriges låga utsläpp av växthusgaser. Samtidigt anses vattenkraften påverka den biologiska mångfalden och vattendragen negativt. Av ungefär 2100 kraftverk står de 200 största för över 90 % av elproduktionen. Det finns alltså ett stort antal småskaliga kraftverk som bidrar med en liten del elproduktion samtidigt som de riskerar att påverka vattendragen negativt. Syftet med den här studien var att undersöka om elproduktionen från småskalig vattenkraft är försvarbar sett till dess miljöpåverkan. Studien använde en kvalitativ metod baserad på semi-strukturerade intervjuer med följande intressenter inom småskalig vattenkraft: Svensk Energi, Svensk Vattenkraftförening, Energimyndigheten, Havs- och Vattenmyndigheten, Naturskyddsföreningen, Sportfiskarna samt Älvräddarna. Resultaten visade att småskalig vattenkraft är en billig och etablerad energikälla, den kan bidra med kulturella värden, den är lokalt producerad och konsumerad som kan ge en ökad stabilitet till elnätet samt minska distributionsförluster. Nackdelarna visar att småskalig vattenkraft saknar några av de viktigaste funktionerna som storskalig vattenkraft kan bidra med: reglering av elnätet samt möjlighet att lagra vatten som kan användas vid behov. Vidare kan småskalig vattenkraft anses ha en stor negativ påverkan på vattendragen och den biologiska mångfalden. Potentialen för småskalig vattenkraft kan också anses vara lägre än för övrig förnybar energi samtidigt som utvecklingen går långsammare. Lagstiftning, tillstånd och elcertifikatsystemet har även identifierats som faktorer som inte hjälper situationen för miljön i vattendragen. Behoven av att producera förnybar el från småskalig vattenkraft kan anses vara lägre än behovet av att värna om vattendragen och den biologiska mångfalden för att nå Sveriges miljökvalitetsmål och EU:s vattendirektiv. Det finns utrymme för att minska elproduktionen från småskalig vattenkraft och ändå nå miljöpolitiska mål om förnybar energi och vattenmiljö. Slutsatsen är att elproduktionen från småskalig vattenkraft inte är försvarbar sett till dess miljöpåverkan och att man bör undersöka möjligheten att ta bort de allra minsta kraftverken med störst miljöpåverkan. Det har också framkommit att det saknas ordentliga styrmedel för att främja biologisk mångfald och vattenmiljöer samt att synen på småskalig vattenkraft som miljövänlig bör ifrågasättas.Today we face many environmental problems such as climate change and biodiversity loss. Hydropower is a renewable energy source that can produce electricity with low greenhouse gas emissions. Sweden has a long tradition of using water as an energy source and has during the past century built hydropower in a majority of the Swedish rivers. Today, hydropower accounts for nearly half of Sweden's electricity production and contributes to Sweden's low greenhouse gas emissions. But hydropower also affects biodiversity and water bodies negatively. Of the approximately 2100 hydropower plants in Sweden, 200 accounts for over 90% of the electricity production. Thus there are a large number of small-scale hydropower plants that contribute to a small portion of the electricity while they are liable to affect streams negative. The purpose of this study was to investigate whether electricity from small-scale hydropower is justifiable in terms of its environmental impact. The study used a qualitative method based on semi-structured interviews with the following stakeholders: Swedenergy, Swedish Hydropower Association, Swedish Energy Agency, Swedish Agency for Marine and Water Management, Swedish Society for Nature Conservation, Swedish Anglers’ Association and River Savers Association Sweden. The results showed that small-scale hydropower is a cheap and established energy source, it can also contribute with cultural values, it is locally produced and consumed that can give greater stability to the electricity grid and reduce distribution losses. The disadvantages show that small-scale hydropower lacks some of the key features that large-scale hydropower can provide: the regulation of the electricity grid and the ability to store water that can be used if necessary. Furthermore, small-scale hydropower is considered to have a major negative impact on streams and biodiversity. The potential for small-scale hydropower could also be considered lower than for other renewable energy while developing more slowly. Legislation, permits and electricity certificate system has also been identified as factors that do not help the environmental situation in streams. The need to produce renewable electricity from small-scale hydropower can be considered lower than the need to protect streams and biodiversity to reach Swedish environmental quality objectives and the Water Framework Directive. There is scope for reducing electricity production from small-scale hydropower and still achieve environmental policy objectives on renewable energy and streams and biodiversity. The conclusion is that electricity production from small-scale hydropower cannot be justified in terms of its environmental impact and that there is a need to examine the possibility of removing the smallest hydropower plants with the greatest environmental impact. It is also stressed that there is a lack of proper incentives to promote biodiversity and aquatic environments and that the view of small-scale hydropower as environmentally friendly should be questioned.

Full textAbstract:
The purpose of this thesis is to investigate the implementation of a political aim – formulatedfrom a context of sustainable development. In 2006 both the Swedish national Parliament andthe municipality of Växjö (among others) stated that 25% of publically served food wouldstem from organic production by the end of 2010. The thesis investigates the outcome of theimplementation of this policy in a local perspective - looking at one part of the public sectorby focusing on four differently organized schools within Växjö municipality. School food in Sweden has a specific institutional setting. It holds the almost unique statusas a non-charged, legal right to all pupils in the compulsory school system. School food as apublic good is affected by the EU legislation of public procurement. The thesis studies theoverall institutional framework (i.e. legislation and regulations) fundamental to school food.With the institutional framework in mind the thesis also describes different organizationalactivities connected to school food. Thus the thesis involves four geographical levels: Theregional (EU), the national, the local and the individual level. The latter is defined in theorganized context from a number of individual professionals. Some of these individuals arefurther considered as so called street level bureaucrats – officials sandwiched between superiorsand their clients. The thesis builds a conceptual framework based on institutional, organizational and streetlevel theory together with policy analysis. Methodologically the thesis is formed around andcarried out as a local case study through a number of semi-structured qualitative interviews.The empirical and analytical part of the thesis is further structured around the three theoreticalconcepts. From the thesis´ purpose three guiding questions were outlined. The main implications of the thesis are that a number of factors were found to be involvedin the policy implementation. The most significant factors for the policy implementation arefirstly the formulation of the political goal, and secondly the individual professionals actuallybuying the food for the schools. As long as the policy of the school food is non-forcing (i.e. anaverage aim of the public sector, and not included in the legislation) the final outcome of thefood depends on the decisions made by the buyer. There is disagreement of the policy intention and of whether organic food is more sustainablethan other food. Thus I end the thesis by suggesting a change of concepts if the politicalaim is to reach sustainability. I encourage a system to control the food´s total ecological footprint.This would be achieved by formulating the policy around a suggested level of the ecologicalfootprint. The level would be calculated and set where experts say it´s in accordancewith sustainable development. From this the street level bureaucrats can sum up the componentsof the lunch they buy and serve. No matter if the individual product is labeled organic,local, conventional, or… This would – according to me – improve the chances for Växjö actually to live up to itslogo: the greenest city in Europe. At least this idea could awake a debate.Opposition kl. 13.15

Denna studie syftar till att undersöka vilka faktorer som påverkar det svenska jordbrukets möjlighet att bidra till biologisk mångfald. Semistrukturerade intervjuer har utförts i Södermanlands och Östergötlands län med jordbrukare, myndigheter och rådgivare. Intervjuer har genomförts med olika aktörer inom jordbruksnäringen för att få ett brett perspektiv på studien. Resultatet av intervjuerna jämförs med tidigare forskning där administrativa, ekonomiska samt sociala faktorer diskuteras. De främsta faktorer som lyfts fram av samtliga respondenter är problemet med dålig lönsamhet för jordbrukare, komplexa regelverk samt brist på kunskap om jordbruksproduktion i samhället. Resultatet av studien visar att respondenterna har liknande upplevelser av de faktorer som påverkar det svenska jordbrukets möjligheter att bidra till biologisk mångfaldThis study aims to investigating factors that influence Swedish agriculture's potential to contribute to biodiversity. Semi-structured interviews have been conducted in the county of Södermanland and Östergötland with farmers, authorities and advisors. Interviews has been conducted with various actors in the agriculture industry to get a broad perspective on the study. The results of the interviews are compared with previous research discussing administrative, economic and social factors. The main factors highlighted by all respondents are the problem of poor profitability for farmers, complex regulations and lack of knowledge about agricultural production in society. The results of the study show that respondents have similar experiences of the factors that influence Swedish agriculture's potential to contribute to biodiversity.

Full textAbstract:
Det svenska sjukvårdssystemet är konstant under hög press och situationen benämns ofta i media som en sjukvårdskris. Radiologin är en av de medicinska discipliner som drabbats av en kontinuerligt ökande arbetsbelastning och personalbrist. Detta sätter sjukvården i en situation att konstant tvingas väga effektivitet mot kvalitet. Trots höga förväntningar på att innovationer som Artificiell Intelligens (AI) ska kunna bistå behoven, används AI idag i en mycket begränsad utsträckning. Denna studie syftar till att utreda påverkande faktorer för införandet av AI inom radiologin. För att besvara arbetets forskningsfråga har HA Adoption-Decision Model, en modifierad version av det väletablerade Technology-Organization-Environment Framework (TOE), tillämpats. Ramverket innefattar tre kontexter; teknologisk, organisatorisk och extern kontext. Varje kontexts delaspekter, så kallade faktorer, följer under respektive kontext. Dessa tio faktorer utvärderades för att besvara studiens forskningsfråga om vilka faktorer som har störst påverkan på införande av AI inom radiologi. Genom att förena tidigare forskning med resultatet från sex intervjuer visade sig affärsvärde , strategisk lämplighet , ledningsstöd och reglering av datahantering ha störst påverkan. Avslutningsvis presenteras ett förslag om att introducera en elfte faktor, IT-mognad, till ramverket.
