This master thesis examined the microstructure after heat treatments in stainless steel, two conventional stainless steel (304 and 316) and two novel high temperature stainless steel. These stainless steels are for the use in high temperature heat exchangers for extended temperature range. The positive characteristics in stainless steel are inversely correlated to grain size, characteristics such
Proteiner som känner stress Några arter av bakterier är bland människans värsta fiender. De gör oss, vår boskap och våra växter sjuka, de får mat att förruttna, förorenar vatten, och mycket mer. Så för att begränsa och bekämpa dessa bakterier värmer, saltar och syrar vi vår mat och förvarar den i kyla, vi steriliserar sår och ytor med desinfektionsmedel, och vi behandlar sjukdomar med antibiotika
Utgångspunkten för studien är att undersöka allmänhetens ställningstagande kring förändringar inom barnavården under tidsperioden 1900 till 1950. Under denna tidsperiod skedde en övergång från att barnavården var en privat angelägenhet till att bli statlig. År 1937 beslutade riksdagen om att införa fri spädbarnsvård för hela landet, sedan sekelskiftet år 1900 hade liknande verksamhet bedrivits av
Syfte: Denna studie vill bidra till och fördjupa nuvarande forskning inom konsumentbeteenden. Syftet är att bidra med en aktuell förståelse för val av handelskanal, genom att studera hur yngre kvinnliga konsumenter resonerar i sina val mellan e-handel och fysisk butik. Dessutom vill studien bidra med en förståelse om yngre kvinnliga konsumenters moral för att skapa en förståelse för konsumenternas
GABAergic Neurotrasmission – A “cross-talker” between inflammation and neural plasticity in stroke Stroke is a leading cause of disability and no pharmacological treatment is currently available to promote recovery in suffering patients. A major part of research is focusing on finding new biological targets which can be pharmacologically intervened with, providing favorable results in facilitatin
The aim of this study was to evaluate and describe the landscape development in an area located in the municipality of Upplands-Bro, Sweden. The main hypothesis was that the landscape patterns in the study area have changed, as I expected to discover that the landscape has undergone structural changes, in form of both changed land use and changed landscape patch composition. The hypothesis was bas
Plant-insect interactions play a crucial role in the evolution of the coevolving web of life, shaping local interaction networks and moulding the diversity and the evolutionary history of two of the most diverse groups of organisms on earth. The interaction between Lithophragma bolanderi (Saxifragaceae), which presents a geographic mosaic of ploidy levels, and the pollinating floral parasite Greya
This paper analyses how China’s growing taste for beef due to rising incomes, urbanization and preference for higher quality meat shaping Kazakhstan’s inefficient beef industry, and how Kazakhstan’s government is attempting to make it more efficient. The analysis done through qualitative methods by looking into the data from primary and secondary sources.
Conventional urban planning doesn’t fit anymore the complexity of new urban challenges (heat island effect, biodiversity loss, human health issues). Instead, alternative methods must coexist with existing strategies for municipalities to be more flexible to changes and stay innovative. This research advocates the use of vacant land in cities for urban agriculture. As a nature-based solution, vacan
A Power Amplifier (PA) is an essential electronic component in all microwave and millimeter-wave applications and, more specifically, in any transmitting system where the level of input power signal needs amplification to the desired level.Linearity and high efficiency are of utmost importance in PAs. However, high-efficiency PAs tend to be non-linear, and PAs working in the linear region might ha
Kings of the Wyld av Nicholas Eames är en fantasyroman som blandar mörka teman med humor och som väver in allusioner till såväl nördkultur såväl som 70-talsrock. I den här magisteruppsatsen diskuterar jag översättning av namn, allusioner och alluderande namn i fantasy, med utgångspunkt i min översättning av två utdrag ur romanen. Uppsatsen inleds med en källtextanalys av hela romanen, med specifik
Högre verkningsgrader, stabilitet och minskad toxicitet; så skall framtidens solceller nå verkligheten. Många hoppas att solenergi ska ta över våra energibehov och varje dag närmar vi oss en grönare utvinning av elektricitet. Kommer våra bilar och byggnader täckas av solceller i framtiden? Inte helt omöjligt, om vi kan bemästra det fascinerande materialet perovskit. På EPFL, Ecóle Polytechnique FPerovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling. Scientists all over the world are working towards solutions and
"Developmental Assets" refer to a series of relevant experiences, relationships, skills and values that can effectively promote the healthy development of children. They are social and psychological strengths that can enhance the healthy development of children and adolescents. Studies have shown that having sufficient developmental assets can develop children's competencies, skills
Background. Released mechanisms were investigated in Pickering emulsions stabilized by quinoa starch granules. Non-heat treated (NHT) and heat treated (HT) emulsions were studied for their stability and for their ability to efficiently encapsulate peptides and give controlled release after partially simulated in vitro intestinal digestion with release systems containing combinations of phosphate b
Recent studies have shown the discriminatory and patriarchal nature of personal status laws in Lebanon (Geagea et al. 2015; Mikdashi 2018b). Stories abound of women losing custody of their children due to laws that favor paternal custody and of couples pursuing civil marriages abroad to avoid being subject to religious courts in Lebanon (Abillama 2018). Literature on the subject has focused on the
Abstract Digital sourcing platforms were invented in the last decade of the 20th century and brought tools such as electronic reverse auctions (eRA) into the hands of purchasing professionals. The Trelleborg Group initiated a project to implement such a digital sourcing platform last year but the research in the field is outdated. Focus was directed to the choice of sourcing approach, i.e. either
This study compares the performance of equal- and value-weighted portfolios using a broad investment universe consisting of the stocks from the Swedish stock market. While implementing random sampling in the portfolio construction procedure, three rebalancing schemes are applied on the equally weighted portfolio in order to observe differences in performance among these. In order to compare how mu
IPO underpricing is an international phenomenon that has been documented by numerous authors. However, the IPO market keeps evolving. Since the decline in IPO volume following the “dot-com bubble”, there have been periods with high IPO volume, as well as periods with low IPO volume. This paper uses a linear regression model and t-tests to investigate underpricing of European IPOs between 2001 and
Wet cupping, or traditional Finnish cupping has been practised in Finland for several centuries. It is a treatment where blood is removed from the body through a ritual-like procedure. The treatment starts with the cupper making small cuts on the skin with a lancet or cuppers axe. Cups are placed over the cuts, and through the vacuum that emerge under the cups blood is drained. Still in the middle
