Detta examensarbete handlar om att undersöka stabiliteten hos Pickering emulsioner som består av myglyol olja, vatten, etanol och stärkelse. Emulsioner med olje- och etanol i vattenhalt upp till 60 % samt 70 % visade sig vara stabila upp till fyra månader vid rumstemperatur. Detta tyder på att Pickering emulsion är stabilt och kan användas för framtida alkohol baserade emulsioner.The aim of this work was to study ethanol based particle-stabilized emulsions, using a known phenomena called Pickering emulsions. The intended uses of the studied emulsions are towards skin formulations, but other applications could be used. The particles of interest were quinoa starch modified with skimmed milk powder and heat treated afterwards. Comparison between modified starch and native sta

The purpose of this project is to research the potential of applying mathematical methods in order to aid the development of robust Head-Up Display systems for automotive vehicles. If the vehicle detects an object and the Head-Up Display should overlay some information over that object, then the information has to be displayed at some position which depends on where the driver is looking from. Thi

Svårläkta bensår är ett stort problem som ökar både i Sverige och internationellt. Författarna gjorde en kvalitativ intervjustudie med åtta distriktssköterskor från tre olika vårdcentral

With millions of yearly beach visitors in southern California, beach water quality represents an important factor in public health and ocean dependent economy. Fecal indicator bacteria (FIB) in water is much easier to measure than disease causing organisms but correlation exists between the two. For this reason, FIB concentrations are used to measure recreational water quality and related health r

Globally 884 million people depend on unsafe drinking water, of which 159 million depend on untreated surface water (WHO, 2017). In Tanzania 44% of the popula- tion lack access to safe drinking water (WaterAid, 2017). Women and children in the small city of Chonyonyo, in Karagwe district are walking several hours a day for contaminated drinking water. According to a study, carried out in TanzaniIn Chonyonyo, a village in north-west Tanzania, the majority of the population have no access to the groundwater beneath them. Every day, women and children walk several hours to a hole shared with animals, to collect contaminated drinking water for their families’ domestic needs. This report shows that the groundwater resources in the area are sufficient to supply the people of Chonyonyo with fre

When households do their grocery shopping some sort of shopping list is used to make the shopping easier. The lists contain the groceries that are intended for purchase. These lists can be boring to make and is also not free from errors, so an automated way to generate these lists would be practical. This Master’s thesis aims to generate these shopping lists with data from past grocery receipts by

Landfill mining - Dagens soptippar som morgondagens gruvor. I takt med att planeten utsätts för allt större miljömässiga utmaningar och minskande resurstillgångar blir arbetet med att styra samhällen mot en mer hållbar utveckling allt viktigare. Trots detta har våra sopor både historiskt och på många platser i världen än idag, hamnat på deponier där potentiellt värdefulla resurser grävts ner. I In a global effort to reduce the human impact on the environment researchers and companies are looking into the prospect to extract valuable resources from discarded waste stacked up in landfills all over the world. Through excavating old landfills (also called: Landfill Mining) greenhouse gas emissions can be avoided, important rescores recovered and at the same time reduce pollutants and provide

The Kenyan central rift has witnessed dramatic climatic changes over relatively short periods of time in response to global climatic changes, with the water levels of the lakes within the rift rising and falling with these changing conditions. There is considerable evidence showing extreme wet and dry phases throughout their existence. These wet and dry phases also influenced the vegetation cover,

The essay, The New Clothes of Death is about the funeral customs in Sweden from a culture-historical perspective with an ethnological touch. The essay deals with our present day relation to death and how this can be transformed to the dead person. The questions are highlighted with observations from two funerals, one cremation and, studies of the cemetery environment and the culture of the graves.

Skuldsaneringsinstitutet kom till för att hjälpa överskuldsatta människor att lösa sina ekonomiska problem när det till synes inte fanns någon annan utväg. Den första svenska skuldsaneringslagen tillkom år 1994 för att möta de behov som bankkrisen under början av 1990-talet hade skapat. Efter det har skuldsaneringsförfarandet utvecklats och förenklats, och förra året kom den tredje versionen av skThe institute of debt reconstruction was founded as a last resort to help people who are heavily in debt to get their finances in order. The first law of debt reconstruction was founded in 1994 to meet the needs created by the banking crisis in the early 1990’s. After that the debt reconstruction procedure has evolved and simplified, and last year came the third version of the law of debt reconstr

Felaktiga domar sker i både Sverige och andra stater. Detta trots att straffprocessen innehåller starka krav på rättssäkerhet så som oskyldighetspresumtionen och rätten att inte bli lagförd två gånger för samma sak. Den senare principen hänger ihop med regeln om att när en dom inte längre kan överklagas får den rättskraft, innebärande att fallet inte får prövas igen i ny rättegång. Alla ordinära rWrongful convictions happen both in Sweden and other countries, even though the criminal justice system is filled with principles regarding the rule of law, such as the presumption of innocence and the right not to be tried or punished twice. The latter is closely linked with the general rule that once a verdict no longer can be appealed, it enjoys legal force (prejudice), meaning the case cannot

Övervikt och fetma hos barn och ungdomar i Sverige har ökat de senaste decennierna. Flera studier visar att om tidig övervikt och fetma hos barn inte får möjlighet till behandling är prognosen dålig till att de kan bli normalviktiga i vuxen ålder. Syftet med litteraturstudien var att beskriva distriktssköterskans erfarenheter av att arbeta med barns övervikt och fetma inom barnhälsovården. Metoden

Om en moder uppsåtligen dödar sitt barn vid födseln eller under vissa förutsättningar efteråt, döms hon för brottet barnadråp. Det innebär att hennes gärning får ett lägre straff än vad som annars blivit fallet vid uppsåtligt dödande. Syftet med denna uppsats är att undersöka bakgrunden till införandet av bestämmelsen om barnadråp och kritiskt analysera om denna särreglering är nödvändig i gällandIf a mother deliberately kills her child at birth or under certain conditions afterwards, she is convicted of the crime infanticide. This means that her deed will be punished with a lower penalty than otherwise in cases of intentional killing. The purpose of this thesis is to investigate the background to pass the crime infanticide in law and critically analyze whether this special regulation is n

The kinetics of the catalytic conversion of ortho- to parahydrogen was studied for the two catalysts, IONEX® and OXISORB®. The study also involved the optimization of an experimental technique for the conversion of orthohydrogen in a static setup. The main focus of the optimization being directed towards the analytical setup, where the acquisition of information and interpretation of the data were

Small molecules, and their fragmentation to smaller constituents upon excitation, are often used to understand how the bonds in a molecule are formed and how they break. One of such widely studied model molecule is CO2. This study aims at extending the knowledge of dissociation of carbon dioxide by measuring also the negatively charged fragments. In addition, these anions are linked to positive io

Accurate quantitative protein analysis is crucial to identify proteins that are differentially abundant between samples, to provide clues about disease mechanisms or act as biomarkers. However, in most workflows, proteins are digested to peptides, and the resulting peptides are quantified as proxies for proteins. No consensus method for going from peptide to protein level quantification exist, and

With the rapid development of Information and Communication Technology (ICT) industry the demand for power has also increased. ICT tends to play a significant role in global greenhouse gas emissions. It was responsible for 10% of world’s total energy consumption in 2010 and is doubling in every 10 years [1]. Cellular networks are among the main energy consumers in the ICT field. To have an environ

Att designa flygplansskrov är en komplicerad process, men den kan underlättas med hjälp av så kallad topologioptimering. Med en nyutvecklad programvara skulle konstruktörer tidigt kunna få fram hur en struktur bör se ut för att uppnå den bästa designen – om programvaran implementeras på ett effektivt sätt. Topologioptimering är en matematisk metod för att få fram den bästa materialdistributionenAlthough topology optimization is a powerful tool for generating the most beneficial material distribution of a loaded structure, it has yet to become a part of the design engineer’s work at Saab Aeronautics. With a newly developed software tool which focuses on the concept phase design, there are hopes that its use can allow the design engineer to generate as optimal concepts as possible early in
