I snart 500 år har människan använt sig av diverse optiska instrument för att betrakta sådant som inte är möjligt att se med blotta ögat. Teleskop har använts för att studera himlakroppar och mikroskop för att exempelvis undersöka små biologiska beståndsdelar. Det finns idag många olika metoder inom optisk mikroskopi men samtliga följer en liknande grundprincip. Objektet som ska avbildas exponerasSeveral significant pathogenic bacteria exhibit surface proteins that bind human antibodies, preventing them from being recognized by the human immune system. These bacteria are thus protected from elimination and can survive in the host organism. One common such bacteria is the Streptococcus pyogenes that exhibits the antibody binding M protein on its surface. Streptococcus pyogenes causes more t

The effects on trade from negotiating and entering voluntary partnership agreement is estimated using forest product trade data from 2000 to 2014 on countries in the Forest Law Enforcement, Governance and Trade (FLEGT) licensing process. Gravity model framework is used and the result shows that beginning negotiations lead to an export drop by approximately 0.6 percent and is relatively stable the

In this thesis, I examine the relation between size and performance in Swedish equity mutual funds during the period 2010 – 2017. The thesis is divided into two main parts with the first part investigating the relation between size and performance by dividing the sample of 107 mutual funds into three groups according to the size of the funds. The funds are then analyzed with three different perfor

Rationale: Urban informal settlements are vulnerable and exposed to hazards. Weather forecasting is possible and provides a “window of opportunity” to push cash or aid to vulnerable dwellers before the disaster strikes. Forecast-based Financing is a framework, which provides this system, and it has had great success with rural pilots. Currently no research has investigated the implementation of Fo

The current thesis examined how employees make sense of employer branding activities tailored for university graduates. A mixed-method approach of conducting qualitative research was use to investigate the nature of tailored employer branding activities. Based on the theory of sensemaking, deeper understanding of the addressed topic was gained.

School-based sex education plays an influential role for adolescents in England. Existing research shows that adolescents are a vulnerable population who are more likely to get a sexually transmitted infection over another age group. Girls between the ages of fifteen and twenty-four are particularly vulnerable to getting an STI. In some countries, a framework called comprehensive sexuality educati

Factors influencing and improving a student’s academic attainments, in particular, test scores, are an essential concern for academics as well as policymakers. In this thesis, I add a student’s ordinal rank, calculated from underlying test scores, as a new input factor to the education production function. By using experimental data on primary schools in the United States, I assess whether the ord

Power systems operate at a specific frequency and constantly require a balance between production and consumption of electricity in order to maintain the frequency within a certain interval. Larger frequency deviations can cause blackouts or damage equipment connected to the grid. Balancing functions that stabilise the grid are referred to as \textit{ancillary services}, which in Sweden include th

Vi i Sverige är duktiga på att återvinna, men man kan ibland fråga sig om återvinning verkligen är det bästa sättet att hantera produkter som man inte längre använder. När det gäller elektroniska produkter så som mobiltelefoner, datorer och surfplattor kan både resurser och pengar sparas genom att återanvända istället för att återvinna. Studien du nu ska läsa är en undersökning om hur skånska koInformation and Communications Technology (ICT) is something that drives our society forward, but how we are consuming these products is rather something that harm our environment rather than pushing our society forward. This thesis investigates our unstainable consumption of ICT products and takes a look at waste prevention solutions in order to reach circular economy with a focus on Swedish muni

Syftet med denna uppsats är att undersöka textbindningen i avsnitt om litteraturhistoria i läroböckerna Svenska för dig. Litteraturhistoria (Ring, 2014), Kontakt. Huvudbok 2 (Bergsten, 2014) och Svenskan 9 (Andersson m. fl. 2016). Avsikten är att se om referensbindningen, den tematiska bindningen och konnektivbindningen kan göras starkare/tydligare. Stark textbindning i läroböcker har enligt studi

In this thesis I investigate the labor market outcomes following the imposition of restrictive measures against unauthorized labor. I do this by studying the causal effects of the Arizona’s migration laws LAWA and SB 1070 on labor market outcomes in terms of employment, wages and the usual hours worked per week. In 2008, Arizona implemented The Legal Arizona Workers Act (LAWA), demanding all emplo

Bakgrund: Delegering av administrering och överlämnande av läkemedel till icke legitimerad personal är en allt vanligare lösning vid brist på sjuksköterskor med hot mot patientsäkerheten som följd. Syfte: Belysa huruvida patientsäkerheten påverkas då administrering samt överlämnande av läkemedel delegeras till icke legitimerad personal. Metod: En induktiv litteraturstudie utifrån tolv studier. Res

The Zapatista movement is a multilayered movement fighting unequal power structures and oppression. The movement has from the beginning incorporated a large number of women, both as members and as supporters. However, does the Zapatista movement recognize the multiple axes of oppression that women within the movement face? The aim of this thesis is to uncover how the theoretical ideas behind the c

The following study concerns the effects that lies behind accounting offenses. Accounting offenses is an important subject to study due to its wide spread throughout and great effect on society. More then 12 000 cases of accounting offenses were reported in Sweden during 2016 alone. The study’s main task was to identify social and normative relations that affect the actors’ actions in the business

One of the larger changes in society that affected individual’s lives during the 20th century is the increase in divorce rates that happened in almost all industrialized countries. It went from being an uncommon feature reserved for the rich to a prominent part of family-life. The increase occurred against the backdrop of economic growth and the industrialization. This study constructs a data set

Following the Arab Spring uprisings, Tunisia remains the only country in the region that has managed to protect a fragile yet successful democratization process. Tunisians have protested against their deteriorating quality of life as well as a lack of political and civil freedoms, with the hope to transform their society into a more developed one. Since then, the country has lived through signific

Bakgrund: Närstående är vanligen det främsta stödet till patienter med cancer i ett palliativt skede och tidigare forskning visar att närstående får ta ett stort ansvar för patientens vård. Syfte: Studiens syfte var att undersöka hur närstående till patienter med cancer i ett palliativt skede bemästrar sin livssituation. Metod: Studien gjordes som en litteraturstudie, som omfattar tio artiklar och

Drastic emission-reductions are needed to avoid the disastrous consequences of climate change. Flying is one of the highest individual carbon-impact actions. By 2050, the aviation industry’s share on global greenhouse gas emissions is expected to rise by 300 to 700%. An intervention to counteract this development is to reduce flying at universities as they have a critical role in leading sustainab

Saudi Arabia constitutes an interesting paradox regarding female labour force participation. Despite high living standards and education levels among women, Saudi Arabia has the largest gender employment gap in the world. The Saudi government addresses this issue in the recently launched National Development Plan Vision 2030 which aims to reconstruct the economy in order to decrease the kingdom’s
