As manufacturing is creating welfare and prosperity, it is important for humankind. Nevertheless, manufacturing is causing the depletion of natural resources, environmental burdens affecting the health of animals, humans and eco-systems, and social conflicts. Thus, it is essential to implement sustainability into manufacturing. Paint shops are however known for being liable for a big part of the large energy consumptions within manufacturing. Therefore, it is necessary to investigate what cost-effective solutions can be implemented in paint shops in order to reduce the energy consumption in a sustainable manner. Hence, the aim of this study was to, from a manufacturing perspective identify possible cost-effective solutions for lowering energy consumption within paint shops. The aim was further divided into two research questions: • RQ1: What are the enablers for energy efficient paint shops? • RQ2: What are the challenges for energy efficient paint shops? The research approach used to answer the aim and research questions were a literature review and a case study. The literature review was performed to get a deeper understanding of the subject and was then complimented with the findings from the case study. The case study was performed at the paint shop of a global automotive manufacturing company in Sweden, which currently have a high energy consumption. The enablers identified were (1) implementation of solar photovoltaic, and an energy storage system, which enables an environmentally friendly way of generating energy on-site and store excess energy for later use. The energy storage system can also be used to save money by utilizing the fluctuating electricity market prices, charging the battery when the energy price is at its lowest. (2) Implementation of an UV-curing system and paint, which is an environmentally harmless method of curing paint. (3) Reducing or disabling the heating, ventilation and air conditioning system of a building when it is not a necessity. (4) Workers commitment and motivation towards sustainability, to ensure everyone’s participation. The challenges identified were (1) the expensiveness of sustainability, allocating and prioritizing it in budgets is challenging for a company since profitability is always a major concern that often overshadows sustainability. (2) The risk of modifying the processes within the paint shop, as the consequences are unexplored. (3) In its current state, the energy consumption of the paint shop is very high, it is hence difficult to provide the whole paint shop with solely solar photovoltaic. (4) An energy storage system requires space and freeing up that space is a challenge without reconstructing existing facilities. (5) With implementation of UV- curing, the paint used must be curable with UV-light. Additionally, complex three-dimensional shapes make it challenging to properly cure evenly with UV-curing. (6) It is not guaranteed whether it is possible to completely shut down heating, ventilation and air conditioning since industrial equipment in general is designed to always run. (7) Sustainability is not a focus and even if it is increasingly requested by society, the commitment of companies is experienced as low. It is challenging to motivate all the employees to work towards sustainability and find ways to always keep sustainability in mind and to prioritize it over other alternatives.

Soil is one of the largest ecosystems being ignored by human activities. Our farming practices and urban constructions have contributed to its degradation, with far-reaching consequences for the water cycle’s equi- librium.Reconnect with nature and learn the methods to assist in its recovery are essential for the survival of all inhabitants on this planet.  My degree project consists of a large research into the water cycle of urban areas, studying the particular case of Stockholm, that leads to the problems of degraded soil. The aim is to understand the relation- ship between water cycle and soil ecosystems and explore potential solutions.  As a result, I have designed KURITA, a learning tool founded upon the ecofeminism values of care, that serves as a learning method for citi- zens to reconnect with soil values and actively participate in its restor- ative process.

Mode I interlaminar fracture of 3k 8-Harness-Satin Carbon cloth, with identical fill and weft yarns, pre-impregnated with Newport 307 resin was investigated through the DCB test (ASTM D5528). Crack propagations along both the fill and weft yarns were considered for both post-bonded (co-bonded) and co-cured laminates. A patent-pending delamination insertion method was compared to the standard Teflon film option to assess its applicability to mode I fracture testing. The Modified Beam Theory, Compliance Calibration method, and Modified Compliance Calibration method were used for comparative purposes for these investigations and to evaluate the validity of the proposed Equivalent Stiffness (EQS) method. Crack propagation, in all specimens, proceeded in a run-arrest manner for both delamination directions. Energy dissipation in the form of transverse yarn debonding, matrix deformation, and out of plane crack growth was witnessed for specimens with delaminations along weft yarns. A complete comparison between post-bonded and co-cured laminates was not achieved. The patent pending delamination insertion method was found to cause fewer instances of non-linear crack initiation behavior than the Teflon insert and, when non-linear behavior did occur, it was less prevalent. The EQS method was found to achieve fracture toughness values within 5% of the other three data reduction methods for 63% of the propagation values and achieved conservative values for over 33% of the propagations. Suggestions for future studies aimed at completing the comparisons above are provided in Chapter 5.

Fast-bränsle-raketer (SRM) har funnit sin plats i en stor mängd tillämpningar sedan deras framkomst mer än 2000 år sedan. En SRMs prestanda är förutbestämd av geometrin av drivmedelskrutet och är begränsad av gjutningsmetoden, som idag främst används i produktion. Forskning inom 3D-skrivning av drivmedelskrut har undersökt nya komplexa geometrier som kan öka prestandan. Studier kring 3D-skrivning med UV-härdning är få till antalet och undersöks i detta projekt. Ett bindemedel av polyuretandiakrylat (PUDA) har syntetiserats och därefter karakteriserats, med och utan diverse monomerer genom dragprovsmätningar och differentialkalorimetri (DSC). Tillsats av tvärbindarna 1,6-hexandioldiakrylat (HDDA) samt trimetylolpropantriakrylat (TMPTA) till PUDA producerade ett mer sprött material. Denna skillnaden var mer påtaglig för TMPTA än HDDA, vilket tillskrivs den högre akrylatfunktionaliteten i den förstnämnda. Den kommersiella produkten Ebecryl 113 har karakteriserats med inerta fyllmedel. Härddjupet (DOC) undersöktes med Ebecryl 113 i ett experiment, vilket påvisade en minskning av härddjupet med ökande mängder aluminium. Orsaken är troligen de reflektiva egenskaperna för UV-ljus som aluminium innehar. Reologiska studier utfördes, från vilka en minskning i viskositet påvisades till följd av en ökad polydispersitet i partikelstorlekarna. 3D-skrivning med kolvextrudering och påföljande härdning med UV-strålning utforskades. Detta visade utmaningar med tekniken som behövs bemästras. I synnerhet uppmärksammades fasseparation och residuell härdning från reflekterat UV-ljus som begränsande faktorer för fortsatt arbete. / Solid rocket motors (SRMs) have found their place in many applications since their conception more than 2000 years ago. The performance of SRMs is determined by the geometry of the propellant grain and is limited by the cast-and-mould production method typically used today. Research has been made on 3D printing propellant grains to explore new complex geometries, which may increase performance. Studies on 3D printing techniques using UV curing are limited and are in this work investigated. A polyurethane diacrylate (PUDA) binder was synthesized and then characterized, with and without various monomers by tensile testing and differential scanning calorimetry. Additions of the crosslinkers 1,6-hexanediol diacrylate (HDDA) and trimethylolpropane triacrylate (TMPTA) to PUDA rendered the final product more brittle. This change was more noticeable for TMPTA than HDDA, as the former has a higher acrylate functionality. The commercial product Ebecryl 113 was also characterized with inert fillers added. A depth of cure (DOC) study with Ebecryl 113 was conducted, which showed a decrease in DOC with increasing amounts of aluminium. This is attributed to the reflective properties of aluminium in the UV spectrum. Rheological studies were conducted and a decrease in viscosity could be seen as a result of increasing the polydispersity of particle sizes. A 3D printing technique using plunger extrusion followed by UV curing was explored, which highlighted challenges which need to be overcome. Most notably, phase separation and residual curing from scattered UV rays are limiting factors for future work.

Questa tesi include tre capitoli che si concentrano sulle politiche pubbliche e la tutela della salute. Il primo capitolo esamina l’effetto dell’incremento delle aliquote dell’IVA su alcune bevande sul loro consumo. I risultati dell’analisi empirica suggeriscono che l'aumento dell'aliquota IVA ha ridotto il consumo di alcolici, birra e bevande gassate, mentre l’effetto sul consumo di vino non è statisticamente significativo. Tuttavia, questo risultato generale cambia se si considerano sotto-gruppi di individui. Il secondo capitolo studia l’impatto del salario minimo sulla salute della popolazione cinese. Le stime indicano che i salari minimi reali sono negativamente e significativamente correlati con lo stato di salute della popolazione sia nel breve che nel lungo periodo, un risultato che potrebbe essere spiegato dalle condizioni di lavoro più stressanti conseguenti all’introduzione di un salario minimo più elevato. Infine, il terzo capitolo analizza gli effetti dei meccanismi di incentivazione sui comportamenti degli operatori sanitari del settore delle cure primarie nell’ambito della gestione dell'ipertensione. La nostra indagine empirica suggerisce che gli incentivi finanziari negativi potrebbero motivare gli operatori sanitari a migliorare la qualità dei servizi legati alla gestione dell'ipertensione, mentre né gli incentivi finanziari né diverse modalità di valutazione delle prestazioni sembrano influenzare la qualità dei servizi. / This dissertation includes three chapters which focus on the relationship between public policies and healthcare. The first chapter examines whether tax policy is effective in changing the unhealthy drinking behaviours of individuals. My findings suggest that the VAT rate increase is effective in reducing the consumption of spirits, beer and carbonated beverages, while it is not effective for wine. However, this general result change when looking at sub-groups of individuals. The second chapter studies how real minimum wages affect population health in China. I conclude that real minimum wages are negatively and significantly related to population health, a result which might be explained by the role of more stressful working conditions as a consequence of a higher minimum wage. Finally, the third chapter analyses the effects of incentive mechanisms on the behaviours of primary health workers and the subsequent effects on the quality of hypertension management. The empirical investigation suggests that negative financial incentives could motivate primary health workers and improve the quality of hypertension management. However, neither positive financial incentives nor different modes of performance evaluation are significantly related to the quality of hypertension management.

Denna studie syftar till att öka förståelsen för hur boendestödjarna beskriver sitt vardagsarbete med brukarnas återhämtning på två boenden med särskild service inom Socialpsykiatriska utförarenheten i Skärholmens Stadsdelsförvaltning. Vi har intervjuat åtta boendestödjare. Valet av respondenter har gjorts utifrån ett kvoturval, fyra boendestödjare från Frösätra samt fyra från Solholmen. Vi har gjort semi-strukturerade intervjuer med samtliga boendestödjarna och utformat en intervjuguide. Intervjuguiden berör fenomen hur personalen på boendena beskriver begreppet återhämtning, hur de arbetar med återhämtning, hur återhämtning nås samt hur personal beskriver sin roll. Resultatet av studien påvisar att återhämtning innebär att den enskilde har möjligheten att återhämta sig från det kaotiska tillståndet samt att den enskilde tar makten över sitt liv. Återhämtning innebär utveckling och att den enskilde är självständig trots att en del av symptomen är varaktiga. Arbetet med återhämtning handlar om att lita på den enskildes förmåga och inte ge upp hoppet. Att se människan bakom symtomen och sjukdomen och därefter lyfta fram det friska. Återhämtning nås genom att den enskilde själv medverkar i sin egen återhämtning, är aktiv och villig att åstadkomma en förändring. / This study aims to increase understanding of how housing supporters describe their everyday work with the users' recovery at two sheltered housing, in Social Psychiatry perform purity of Skärholmens District Administration. We interviewed eight housing supporters. The selection of respondents was made based on a quota sample, four housing supporters from Frösätra and four from Solholmen. We did semi-structured interviews with all housing supporters and designed an interview guide. The interview guide affects phenomena such as how staff describes the concept of recovery and work on recovery. How the recovery is accessed and how staff describes their role. The results of this study demonstrated that recovery means that the individual has the ability to recover from the chaotic state, and that the individual will take charge of their lives. Recovery involves the development that the individual is autonomous although some symptoms are lasting. The work of recovery is about trusting the individual capacity and to not give up hope, to see the person behind the symptoms and the disease and highlight the healthy. Recovery achieved by the individual themselves take part in their own recovery, are active and want to make a change.

La limitation de perméation des gaz aux bordes de l’encapsulation des photovoltaïques organiques flexibles a été adressée par l’identification des chemins de perméation du vapeur d’eau et par la formulation des nanocomposites adhésives. Une version modifiée du test de calcium optique a été développée pour identifier l’importance des chemins de perméation différents présent dans l’encapsulation des modules photovoltaïques organiques flexibles. Les nanoparticules des phyllosilicates et les nanoparticules des zéolithes ont été dispersées dedans les formulations des adhésifs différents incluant les adhésifs acryliques sensibles à pression et les adhésifs UV réticulables. Les propriétés mécaniques, optiques, et barrières de vapeur d’eau des nanocomposites ont été caractérisés en plus de leur photo-stabilité sous irradiation UV. Les nanocomposites ont été également utilisés pour encapsuler les cellules photovoltaïques organiques et la stabilité des dispositifs a été évaluer sous les conditions de vieillissement accélérés d’humidité et température. / In order to address the issue of lateral water and oxygen permeation through the sides of the encapsulation and into flexible organic photovoltaic (OPV) devices, the water vapor permeation pathways were identified and several adhesive nanocomposites formulated and tested to limit these pathways. To identify the relative importance of the various water vapor permeation pathways present in the encapsulation of flexible OPV devices, a modified version of the optical calcium test was developed. Passive nanoparticles (phyllosilicates) and active nanoparticles (zeolites) were both evaluated dispersed in UV curing acrylate adhesives and acrylic block copolymer pressure sensitive adhesives. The nanocomposites were characterized for their mechanical and optical properties as well as their water vapor permeation and UV photostability. The adhesives were also used to encapsulate OPV devices and tested in accelerated humidity aging.

In recent years, due to growing environmental awareness, considerable attention has been given to the development and production of natural fibre reinforced polymer (both thermoset and thermoplastic) composites. The main objective of this study was to reinforce epoxy and polylactic acid (PLA) with hemp fibre to produce improved composites by optimising the fibre treatment methods, composite processing methods, and fibre/matrix interfacial bonding. An investigation was conducted to obtain a suitable fibre alkali treatment method to: (i) remove non-cellulosic fibre components such as lignin (sensitive to ultra violet (UV) radiation) and hemicelluloses (sensitive to moisture) to improve long term composites stability (ii) roughen fibre surface to obtain mechanical interlocking with matrices (iii)expose cellulose hydroxyl groups to obtain hydrogen and covalent bonding with matrices (iv) separate the fibres from their fibre bundles to make the fibre surface available for bonding with matrices (v) retain tensile strength by keeping fibre damage to a minimum level and (vi) increase crystalline cellulose by better packing of cellulose chains to enhance the thermal stability of the fibres. An empirical model was developed for fibre tensile strength (TS) obtained with different treatment conditions (different sodium hydroxide (NaOH) and sodium sulphite (Na2SO3) concentrations, treatment temperatures, and digestion times) by a partial factorial design. Upon analysis of the alkali fibre treatments by single fibre tensile testing (SFTT), scanning electron microscopy (SEM), zeta potential measurements, differential thermal analysis/thermogravimetric analysis (DTA/TGA), wide angle X-ray diffraction (WAXRD), lignin analysis and Fourier transform infrared (FTIR) spectroscopy, a treatment consisting of 5 wt% NaOH and 2 wt% Na2SO3 concentrations, with a treatment temperature of 120oC and a digestion time of 60 minutes, was found to give the best combination of the required properties. This alkali treatment produced fibres with an average TS and Young's modulus (YM) of 463 MPa and 33 GPa respectively. The fibres obtained with the optimised alkali treatment were further treated with acetic anhydride and phenyltrimethoxy silane. However, acetylated and silane treated fibres were not found to give overall performance improvement. Cure kinetics of the neat epoxy (NE) and 40 wt% untreated fibre/epoxy (UTFE) composites were studied and it was found that the addition of fibres into epoxy resin increased the reaction rate and decreased the curing time. An increase in the nucleophilic activity of the amine groups in the presence of fibres is believed to have increased the reaction rate of the fibre/epoxy resin system and hence reduced the activation energies compared to NE. The highest interfacial shear strength (IFSS) value for alkali treated fibre/epoxy (ATFE) samples was 5.2 MPa which was larger than the highest value of 2.7 MPa for UTFE samples supporting that there was a stronger interface between alkali treated fibre and epoxy resin. The best fibre/epoxy bonding was found for an epoxy to curing agent ratio of 1:1 (E1C1) followed by epoxy to curing agent ratios of 1:1.2 (E1C1.2), 1: 0.8 (E1C0.8), and finally for 1:0.6 (E1C0.6). Long and short fibre reinforced epoxy composites were produced with various processing conditions using vacuum bag and compression moulding. A 65 wt% untreated long fibre/epoxy (UTLFE) composite produced by compression moulding at 70oC with a TS of 165 MPa, YM of 17 GPa, flexural strength of 180 MPa, flexural modulus of 10.1 GPa, impact energy (IE) of 14.5 kJ/m2, and fracture toughness (KIc) of 5 MPa.m1/2 was found to be the best in contrast to the trend of increased IFSS for ATFE samples. This is considered to be due to stress concentration as a result of increased fibre/fibre contact with the increased fibre content in the ATFE composites compared to the UTFE composites. Hygrothermal ageing of 65 wt% untreated and alkali treated long and short fibre/epoxy composites (produced by curing at 70oC) showed that long fibre/epoxy composites were more resistant than short fibre/epoxy composites and ATFE composites were more resistant than UTFE composites towards hygrothermal ageing environments as revealed from diffusion coefficients and tensile, flexural, impact, fracture toughness, SEM, TGA, and WAXRD test results. Accelerated ageing of 65 wt% UTLFE and alkali treated long fibre/epoxy (ATLFE) composites (produced by curing at 70oC) showed that ATLFE composites were more resistant than UTLFE composites towards hygrothermal ageing environments as revealed from tensile, flexural, impact, KIc, SEM, TGA, WAXRD, FTIR test results. IFSS obtained with untreated fibre/PLA (UFPLA) and alkali treated fibre/PLA (ATPLA) samples showed that ATPLA samples had greater IFSS than that of UFPLA samples. The increase in the formation of hydrogen bonding and mechanical interlocking of the alkali treated fibres with PLA could be responsible for the increased IFSS for ATPLA system compared to UFPLA system. Long and short fibre reinforced PLA composites were also produced with various processing conditions using compression moulding. A 32 wt% alkali treated long fibre PLA composite produced by film stacking with a TS of 83 MPa, YM of 11 GPa, flexural strength of 143 MPa, flexural modulus of 6.5 GPa, IE of 9 kJ/m2, and KIc of 3 MPa.m1/2 was found to be the best. This could be due to the better bonding of the alkali treated fibres with PLA. The mechanical properties of this composite have been found to be the best compared to the available literature. Hygrothermal and accelerated ageing of 32 wt% untreated and alkali treated long fibre/PLA composites ATPLA composites were more resistant than UFPLA composites towards hygrothermal and accelerated ageing environments as revealed from diffusion coefficients and tensile, flexural, impact, KIc, SEM, differential scanning calorimetry (DSC), WAXRD, and FTIR results. Increased potential hydrogen bond formation and mechanical interlocking of the alkali treated fibres with PLA could be responsible for the increased resistance of the ATPLA composites. Based on the present study, it can be said that the performance of natural fibre composites largely depend on fibre properties (e.g. length and orientation), matrix properties (e.g. cure kinetics and crystallinity), fibre treatment and processing methods, and composite processing methods.

Alzheimers sjukdom är en smygande neurodegenerativ demenssjukdom som främst drabbar äldre och som karakteriseras av uppkomsten av amyloidplack och neurofibriller i hjärnan. De vanligaste symptomen är demens, kognitiva problem, inbillningar och aggressivitet. Alzheimer förekommer i två olika former, presenil och senil alzheimer. Den fullständiga mekanismen bakom alzheimer är ännu okänd men två proteiner, beta-amyloid och tau, anses ligga bakom orsaken till alzheimer. Ett tredje inblandat protein som man funnit via genetisk analys är apolipoprotein E. Idag är alzheimer ett växande problem, detta i takt med att världens befolkning blir allt äldre. En problematik finns idag då den symptomatiska behandling som finns mot alzheimer anses vara otillräcklig, ett botemedel eftersträvas därför. Immunterapi är ett botemedel som man i framtiden hoppas kunna erbjuda, detta i form av ett aktivt eller passivt vaccin verksamt mot beta-amyloid. Forskning för att finna ett sådant pågår därför just nu. AN-1792 (aktivt vaccin), CAD106 (aktivt vaccin), Bapineuzumab (passivt vaccin) och Solanezumab (passivt vaccin) är fyra vaccin som har tagits fram och testats på människor. I de vaccinstudier som gjorts har motgångar stötts på men även framgångar gjorts. AN-1792 är det vaccin som visat sig vara effektivast men med svåra biverkningar medan CAD106 är det vaccin som visat sig vara mindre effektivt men säkrast. Bapineuzumab och Solanezumab visade sig däremot båda två vara overksamma. Då flera av de vaccin som framställts har varit verksamma mot amyloidplack anser forskare att ett framtida vaccin mot alzheimer är möjligt att framställa. / Alzheimer’s disease is an insidious neurodegenerative dementia disease that primarily affects elderly and is characterized by the formation of amyloid plaques and neurofibrillary tangles in the brain. The most common symptoms are dementia, cognitive problems, delusions, and aggressiveness. Alzheimer’s occurs in two forms, presenile and senile Alzheimer’s disease. The complete mechanism behind Alzheimer’s is still unknown but two proteins, beta-amyloid and tau, are considered to be behind the cause of Alzheimer’s. A third protein involved that was found through genetic analysis is apolipoprotein E. Today, Alzheimer’s is a growing problem as the world’s population is getting older. A complex of problems exists as the symptomatic treatment available against Alzheimer’s is considered to be insufficient; a cure is therefore aimed at. Immunotherapy is a cure that hopes can be offered, this in the form of an active or a passive vaccine effective against beta-amyloid. Research to find such a vaccine is therefore under progress right now. AN-1792 (active vaccine), CAD106 (active vaccine), Bapineuzumab (passive vaccine), and Solanezumab (passive vaccine) are four vaccines that have been developed and tested on humans. In the vaccine studies that have been done setbacks have been encountered but also successes have been made. AN-1792 is the vaccine proved to be effective but with severe side effects while CAD106 is the vaccine proved to be less effective but safer. Both Bapineuzumab and Solanezumab showed to be ineffective. Since several of the produced vaccines have been active against amyloid plaques scientists believes that a future vaccine against Alzheimer’s disease is possible to make.
