In the 1940-ies curtain walls were introduced, i.e. brick walls that do not have any bearing function but served as a front material. Horizontal reinforcement was used in this kind of walls, partly over and under openings or, in undisturbed wall fields, every 5-6th bed joint. In this work the tensile bond strength of mortar joints repaired with an injection tool and a manual method respectively is
This Master Thesis has been performed as a development project for Asko Cylinda AB in Vara, Sweden. The company develops, manufactures and markets conventional tumble dryers among many other products. An important part of a tumble dryer is the filter holder with belonging fuzz filters mounted on the door of tumble dryer’s. The fuzz filter’s objective is to filtrate the hot drying air that pass thr
Buildings alone consume more than a third of the final energy consumption in Sweden, and contribute to approximately 20% of carbon dioxide (CO2) gas produced. This trend is especially worrying in the commercial building sector, because of the rate of increasing use of electricity, as compared to heat or primary fuel consumption. The requirements for energy performance of buildings has since been c
The formation of industry standards for environmental issues and corporate social responsibility is gaining acceptance but the number of successfully implemented programs are few. On an individual level companies have for some time applied company standards or codes of conduct. But on a collective level cooperation seems much more difficult. Although from an economic point of view there are clear
Populärvetenskaplig sammanfattning: Mer än två miljarder människor, mestadels i utvecklingsländer, saknar tillgång till moderna energikällor eller elektricitet. Behovet av rena, effektiva, pålitliga och ekonomiskt överkomliga energitjänster är en viktig fråga i utvecklingsländer, särskilt för landsbygden, där merparten av befolkningen bor. Förnyelsebara energikällor i form av småskaliga vattenkrafOver 2 billion people, mostly in developing countries, have no access to modern fuels or electricity. The necessity of clean, efficient, reliable and affordable energy services is a crucial issue in developing countries, especially in the context of rural areas where the majority of the people lives. Renewable energy sources in shape of small-scale hydropower systems are a complement or alternativ
Syftet med uppsatsen är att utreda om aktiebolaget som associationsform är värdeskapande för skolväsendet och om det aktiebolagsrättsliga vinstsyftet är förenligt med de mål och värden som uppställs för skolan. Uppsatsen diskuterar de risker som aktiebolaget innebär för skolan och analyserar möjligheterna att, inom ramen för vinstsyftet, ta hänsyn till skolväsendets intressen. Efter friskolerefor
This study investigated the applicability of mixture experimental design-based modeling approach to analyze insecticidal activity of thyme essential oils, particularly focusing on the synergistic interaction of their major constituents against Musca domestica. Chemical compositions of twelve commercially available thyme oils were analyzed using GC-MS, revealing their major constituents to be α-pin
Vatten är inte en vanlig vara och bör därför inte heller betraktas som en sådan. Dess avgörande egenskaper och svåra hantering gör att kraven på välfungerande institutioner är stora, men gör också den ekonomiska analysen mer komplicerad. Traditionella, ekonomiska lösningar på externaliteter och effektivitetsproblem går inte alltid att ena med de rättvise- och moralaspekter som uppkommer när det ha
Öresundsregionen är en mycket aktiv region med över tjugotusen människor som arbetspendlar dagligen. Rent fysiskt är det idag lättare att pendla över Öresund än förr, tack vare Öresundsbron. Det finns dock andra hinder. Sveriges regler för sociala avgifter och på inkomstskatteområdet skiljer sig en hel del från Danmarks och denna diskrepans kan ge upphov till vissa problem. Uppsatsen är inriktad pThe Öresund region is a very active region with over twenty thousand people commuting daily across Öresund. Nowadays it is, physically, easier to commute than before, thanks to the Öresund bridge. There are however other remaining obstacles. The legislation of the social insurance scheme and the income tax area in Sweden is different from the corresponding areas in Denmark and the discrepancy may
Many extensions of the Standard Model predict new resonances decaying to a Z, W, or Higgs boson and a photon. This paper presents a search for such resonances produced in pp collisions at s=13 TeV using a data set with an integrated luminosity of 36.1 fb-1 collected by the ATLAS detector at the LHC. The Z/W/H bosons are identified through their decays to hadrons. The data are found to be consisten
Popular Abstract in Swedish Bortglömda, stulna eller på andra sätt borttappade radioaktiva strålkällor som kan anses vara farliga för allmänheten kallas herrelösa strålkällor. Denna avhandling handlar om metoder för att hitta herrelösa strålkällor som emitterar s.k. gammastrålning, bestående av ljuspartiklar med mycket hög energi. Gammastrålning har god förmåga att penetrera materia och kan därförHazardous radioactive sources out of regulatory control are referred to as orphan sources. Focussing on gamma-emitting orphan sources, this thesis describes methods that can be used in mobile gamma-ray spectrometry to perform real-time discrimination between an actual source signal and the signal due to the natural radiation background. Two categories of methods for orphan source detection are pre
Evidence on the association between dietary flavonoids and lignans and breast cancer (BC) risk is inconclusive, with the possible exception of isoflavones in Asian countries. Therefore, we investigated prospectively dietary total and subclasses of flavonoid and lignan intake and BC risk according to menopause and hormonal receptor status in the European Prospective Investigation into Cancer and Nu
To evaluate the pharmacokinetics and safety of oral panobinostat in patients with advanced solid tumors and varying degrees of hepatic function. Patients with advanced solid malignancies, acceptable bone marrow and renal function, and normal or impaired hepatic function, per NCI-ODWG criteria, were eligible. Initially patients received a single oral dose of 30 mg panobinostat for a 1-week pharmaco
Mitigation of greenhouse gas (GHG) emissions is essential for us humans to curb climate change. Around a fifth of the anthropogenic GHG emissions stem from the construction sector. Much come from energy used for space and water heating within buildings, but an increasing proportion comes from the manufacturing of the building materials and is virtually embodied within buildings. This is called Emb
A year after the establishment of the protest camp Palestinagård at Lund’s University in May 2024 and its demolishment by the authorities, the student solidarity movement is continuously engaged in endeavours to get into conversations with the institutions at Lunds University to make their demands heard, as the genocide on the Palestinian population in Gaza is still ongoing. Further, Palestinagård
