The Defunctionalization of carbonyl functionality into methylene by metal-catalyzed hydrosilylation is very important in organic synthesis. But very less work is done in literature because of the need for a large amount of energy for C-O bond dissociation. Metal-catalyzed defunctionalization of carbonyl compounds in the presence of silanes as a mild reducing agent is studied because of its presenc
Befolkningen i Sverige står inför en demografisk utveckling och en allt större andel av Sveriges befolkning kommer vara äldre. År 2018 estimerades att andelen personer äldre än 80 år kommer öka med upp till hela 50 procent i Sverige under de närmaste tio åren Det leder i sin tur till en större påfrestning på landets vård och omsorg och det kommer behövas fler äldreboenden för att möta den ökande eThe Swedish population is facing a demographic development that will result in a larger proportion of the population being older than it is today. This will lead to a greater strain on the country’s health- and elderly care systems. In 2018, it was estimated that the proportion of people older than 80 years will increase by as much as 50 % in Sweden over the next ten years. With an increased numbe
Syftet med den aktuella studien var att, med kvalitativ och explorativ ansats, undersöka förutsättningarna för föräldrar till barn med autismspektrumtillstånd (AST) att skapa trygg anknytning för sina barn, utifrån en förståelse för deras tankar och känslor om sin relation med sitt barn, och sitt föräldraskap – så kallade omvårdnadsrepresentationer. Vidare syftade studien till att undersöka huruvi
Förpackningar är viktigare än vad man kan tro! De skyddar den värdefulla produkten från oönskade bakterier som kan göra att den blir dålig. För att drycken ska hålla längre så måste förpackningen behandlas för att ta bort allt som kanske kan skada personen som dricker innehållet. Man ser också till att bakterier utanför förpackningen inte kan ta sig in. Detta innebär att förpackningen är aseptisk.Sealing of the transverse seal (TS) represents a fundamental step in the assembling of aseptic packages. To prevent the package from being penetrated by gases and pathogens the TS must be tightly sealed. An understanding of the conditions that influence the flow and deformation of polymers is instrumental to designing sealing systems that are reliable and effective. This thesis was focused on cons
This research explains the distribution of rewards within the innovative economic practice of online motorcycle taxi services in Indonesia. Those analyzed are online transportation platforms and their driver-partners. These two are analyzed using the theoretical framework of the innovation economy, which is conceptualized as cumulative, uncertain, and collective economic processes by Mariana Mazzu
This essay focuses on the phenomenon of the new man and new masculinity and how it is used and described in fashion articles. The phenomenon points at something new but within a historical context we see that the new man goes back in history. The aim of this essay is to find what the new man and its new masculinity is today according to fashion journalism. The empirical data consists of ten fashio
Syftet med den här studien har varit att tolka hur unga män i åldern 18–24 år utifrån emotionssociologisk synvinkel upplever känslan av rädsla och trygghet, och hur de utifrån ett genusperspektiv talar om känslor. Vidare har studien undersökt vad som bidrar till de unga männens känsla av rädsla och trygghet. Detta har gjorts genom en kvalitativ metod i form av fem semi strukturerade intervjuer med
Abstract The utilization of one-carbon compounds, such as methanol, as a feedstock for production of high value compounds is a fast developing area within cell factory engineering. Methanol is a cheap and easily stored compound, which can be produced from CO2 and renewable energy. Engineering microbial cell factories for utilization of methanol could therefore contribute to decreasing the amounts
Society and companies are becoming increasingly digitized. If you compare company structures historically and today you will see some palpable differences. Today, there are companies that work almost exclusively digitally. Therefore, a new focus is created on assets that lack physical form, that is intangible assets. These are dealt with today within the accounting regulations and practices, but t
n this master’s thesis, one studies the liquidity of bonds. One considers bid-ask spread and develops four estimators of this liquidity measure based on trading data. One also computes Amihud’s measure. This approach helps to determine liquidity and its associ-ated costs without quotation. One finds out that the Roll, the FHT estimators and the Amihud measure take the lead. One looks at the changes
The aim of this thesis is to describe and explain how meal-box, as a digital device designed to assist households in carrying out eating practices, reconfigure household practices and enable specific behavioural activities, including sustainability. Taking a socio-material and practice theory approach and drawing on an ethnographic study of three meal-box providers – The Seasons, Hello Fresh and L
Studier har visat att det kan göras bra bedömningar av trafiksäkerhetstillstånd och dess bidragande faktorer genom att studera konflikterna i trafiken istället för olyckorna. Genom att undersöka hur konflikterna i en trafikplats ser ut kan man få mer data och få den mycket snabbare än om man undersöker olycksdata. Genom att använda nya verktyg till datorer som djupinlärning kan man även lättare taStudies have shown that good assessments can be made of traffic safety conditions and contributing factors by studying the conflicts in traffic rather than the accidents. By analysing the conflicts in a location with traffic you can get more data and in a shorter time-frame than if analysing accident data. By using new tools for computers such as deep learning, it's easier to get these conflic

As one of the most important sites in which and through which discourse is articulated and disseminated, newspapers play particularly extensive roles in furthering understandings of human rights cases involving citizens of dual nationality and foreign policy. Drawing on critical discourse analysis and the practice of journalistic framing, this study examined the effects of intertextuality on the d
The modernization of China comes as one of the most interesting topics not only at this moment but also has been researched for a long time. The individualization theories come as a result of modernity. This thesis draws on ten in-depth interviews in order to analyze the individualization among the educated, middle-class young people who were born in the 1990s by testing Yan Yunxiang’s theories of
Climate change, along with grassland degradation, have become major causes of livelihood difficulties for herdsmen in Inner Mongolia for the past few decades. The purpose of this study is to seek better understanding of the relationships between climate change and herders’ livelihoods in pastoral communities in Inner Mongolia, map out the major institutional changes on climate adaptation measures
En app/prototyp gjord för studenter av studenter. Den har i syfte att vara deras bästa vän under studiens gång. Hjälpa till med allt från att boka datorsal till att fungera som ett digitalt LU-kort! Nyckeln till ett smidigare studentliv helt enkelt! En första version av prototypen gjordes i en såkallad “lofi-prototyp” som en enkel digitalt handritat prototoyp, som testas först på användarna i fo
As the entertainment industry continues to grow and fictional characters holding enormous value, this paper seeks to explain how the characters can be protected within the EU through copyright or the use of trade marks, and what the limitations to such protection might be. The paper is using a legal analytical method and looks at both the legislation and the case-law within the union, but also at
European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs. Inve
