Lösningsmedel är vätskor i vilka nästan all kemi utspelar sig, såsom tillverk- ningen av kemiska ämnen (t.ex. mediciner), extraktioner av ämnen, eller separationer av olika ämnen. Inom framförallt läkemedelsindustrin används enorma mängder lösningsmedel, vilket är ett stort problem eftersom nästan alla vanliga lösningsmedel är giftiga, miljöfarliga, och brandfarliga. Så kallade gröna lösningsmedelCO2-expanded liquids (CXLs) are a class of solvent systems that have shown great promise as a green and effective medium in synthesis, catalysis, extractions, and analytical separation methods. Unfortunately, not much information is available on the polarity and miscible compositions of CXL systems, information which is crucial for selecting the right solvent system for a particular application.

Jane Eyre (1847), written by Charlotte Brontë, remains a classic, 170 years later. Mr. Rochester’s secret wife locked away in an attic, Bertha Mason, is the antagonist in the novel. However, in Wide Sargasso Sea (1966) written by Jean Rhys around a century later, the character has been rewritten as Antoinette Cosway. This essay examines how Bertha and Antoinette are written and investigates the as

Discussion on whether syndicated loan structures may give rise to anticompetitive risks has been increasing thus the European Commission is performing a study on the impact syndicated lending structures have on competition in the credit markets. This thesis will cover the main aspects of syndicated loan structures and then examine Article 101 TFEU and anticompetitive conduct. Syndicated lending h

The Białowieża forest is one of Europe’s only remaining lowland broadleaved forests still containing a complete contemporary assemblage of browsing ungulates and predators. The presence of gray wolves (Canis lupus) causes behavioural responses in browsing ungulates, the result of which has an impact on lower trophic levels. The impact of this top-down control on browsing lawns (areas of trees main

In today’s post-industrial cities, how urban citizenship is defined and performed have been ambiguously positioned in their relationship with the urban societal space. While the cities become more commodified and privatized with the inter-urban competition, the concept of citizenship is put into a tentative position between being participatory political subjects and passive consumers. Sexuality, i

Rollen av små RNA-molekyler vid omvandlingen av glatta muskelceller Backgrund Blodkärlens viktigaste funktion är att transportera syrerikt blod och näringsämnen till de enskilda organen. Det mellersta lagret i blodkärl består av glatta muskelceller som producerar rikligt med elastiska fibrer. Vid olika typer av kärlskada kan den glatta muskulaturen förlora sin elasticitet och förändra fenotyp vil

Modellering av kreditrisk på ett nordiskt finansiellt institut Kreditrisk är en av de största riskerna som finansiella institut ställs inför idag och det är av yttersta vikt att man kan modellera och hantera denna risk korrekt. Inte minst för att undvika en onödigt stor kapitalbindning – men även för att motverka uppkomsten av finansiella kriser. Logistisk regression Den vanligaste modellen för atCredit risk is one of the greatest risks facing financial institutions, and it is therefore very important that models with good predictive power are used in order to etter capture this risk. This thesis proposes logistic regression models for modelling risk-drivers of the probability of default in a financial institution active in he Nordics. The thesis focuses on handling and analysing large amo

Big data-analyser är ett kraftfullt verktyg för många organisationer idag. Genom att analysera stora mängder data kan organisationer se mönster, trender, dra slutsatser och förutspå saker som ännu inte skett. Men även om fördelarna med teknologin är många så kan Big data-analyser kränka den personliga integriteten på många sätt. I samband med införandet av den nya Dataskyddsförordningen och de öka

Självkörande bilar är ett hett forskningsområde och utvecklingen går snabbt framåt. För att teknologin ska vara säker krävs det att alla bilar har en uppdaterad karta över hur vägnätverket ser ut. Om bilen ska kunna använda kartan för navigering behöver den innehålla information om mer än bara var man kan svänga. Information ner på centimeterprecision om vägskyltar, trafikljus, vägmarkeringar och Technology advancement in autonomous driving is accelerating. For the technology to be safe it is crucial for the vehicles to have an updated map, meaning all vehicles should have a correct and identical representation of the current road network. This makes change detection in the maps of great importance, in order to continuously understand and recognize the features that need to be updated. Th

The amount of wind turbines in Sweden has more than doubled in the last five years. Wind turbines can affect birds directly, by causing fatalities and indirectly, through habitat destruction, disturbance and barrier effects resulting from turbine construction and operation. To increase understanding of how this rapidly expanding form of energy harvesting affects avian communities in Sweden large,

The aim with this thesis is to broaden the understanding of women’s experiences with separatism in the Swedish Facebook group “Växtgäris”. There are few studies written about the importance of separatism for women, and even less about separatism within social networks. I have therefore interviewed four members from Växtgäris who all claim the need of having a place free from men. Of respect, this

Denna uppsats syftar till att undersöka hur organisationer anpassar sitt arbete med kompetensförsörjning till dagens flexibla arbetsmarknad och arbetsliv. Studien utgår från två frågeställningar där den första frågeställningen handlar om hur HR-praktikerna i de valda organisationerna beskriver begreppen flexibilitet och kompetensförsörjning. Den andra frågeställningen handlar om hur de valda organ

Individual inventors have played an important role in shaping modern economic growth with their inventions. However, the upsurge in corporate and institutionalised research and development (R&D) has overshadowed the individual inventor in both academia and policy research. In Sweden, the individual inventor continues to provide socially and environmentally beneficial innovations that solve pro

Forskning visar nu entydigt att den globala genomsnittstemperaturen stiger och att antropogena växthusgasutsläpp i stor utsträckning är orsaken till detta. Medan klimatförändringen är en global angelägenhet, är det också en fråga om stor orättvisa. De utvecklade länderna har generellt sett bidragit mest till klimatförändringarna, men effekterna kommer att bli värre för dem som har bidragit minst. Scientific findings now unequivocally show that the global average temperature is rising and that anthropogenic greenhouse gas emissions are largely responsible for this. While climate change is a global concern, it is also a concern of great injustice. Developed countries have generally contributed most to the climate changes, but the impacts will strike harder on those who have contributed least

Breast cancer is the most common type of cancer among the female population in Sweden. Genomic mutations of patients are a very important source of information for treatment choice and outcome prediction. RNA-sequencing (RNA-seq) has become the de facto standard for expression profiling and can also be used for the detection of genomic variants. However, RNA-seq-based variant detection suffers fro

In recent years, the awareness and concern for operational risk in financial institutions have increased, and several disastrous events in the last two decades been caused by human error. With this, the regulatory demands have increased on the financial institutions to control operational risk. One operational risk that Svenska Handelsbanken AB (SHB) has detected are the audit changes of trades wh

Specifically, I look at how gender structures entrepreneurial practice for young women and how incubators contribute to the gendered construction of entrepreneurship. The study is based on ethnographic data in the form of interviews and observations. I draw on the theoretical concepts of “gender performativity” and “

Abstract The amortization requirement stipulates that all new mortgages will be amortized in the interval between 50-70 per cent of the residence value; an additional, stricter, amortization applies if the mortgage exceeds 450 per cent of the individual´s gross annual income. The stricter amortization requirement is brand new, implemented the 1st of March 2018. This action was introduced when t

Non-communicable, or chronic, diseases (NCDs) are the major contributors to the mortality worldwide. In Ukraine, where the primary causes of deaths are chronic cardiovascular diseases, a healthcare domain suffers from insufficient financial provision, facilities and resources, and the lack of attention to social aspects of poor health conditions. The aim of this research is to explore social conse
