Täppt näsa, halsont och nysningar är symtom du säkert har upplevt vid en förkylning. Förkylningar är vanligast under våren och hösten och orsakas oftast av Rhinovirus. Även om en förkylning oftast är en lindrig åkomma för de flesta så kan den ha allvarliga konsekvenser för personer med nedsatt immunförsvar eller underliggande sjukdom. Förkylning sprids via direktkontakt, indirekt kontakt (såsom Airborne viral diseases have long been neglected but with the recent devastating impact of the COVID-19 pandemic serving as a catalyst for new science, additional viruses are examined. This thesis investigates the infectivity of Rhinovirus, the virus causing common cold, in differently sized bioaerosols. The experimental setup utilized a bio-aerosol nebulizing generator (BANG) to generate droplets
Sot är en produkt som kommer ifrån ofullständig förbränning av olika bränslen, som fossila bränslen och biogaser. Sot produceras därför, bland annat, i många av våra fordon, så sot släpps ut i stora mängder. Sot har en negativ påverkan på miljö och mänsklig hälsa. Det finns olika typer av sot. De som absorberar ljus bättre och har större klimatpåverkan kallas moget sot, medan sot med sämre ljusabsSoot is a known contributor to climate change due to its strong light absorption possibility. It has been shown that adding alkali salts during the soot formation reduces its soot absorption ability, and thus reduces its impacts, but the exact mechanics are not fully understood. This thesis aims to get a better understanding of the effects that salts have on soot. The salts used were sodium chlori
This paper uses nissological theory in order to ascertain the connection between Eurosceptic voting tendencies or lack thereof, and three elements often associated with island dwelling, those being physical, legal, or identity-based separation. The author has chosen four distinct island regions from around Europe, more specifically Sicily, Crete, Azores and Åland. After an explanation of the basic
Introduction: PARP15 belongs to the PARP family, which carries out ADP-ribosylation, a post- translational modification involved in DNA repair. Finding selective inhibitors can help discover more of the role PARP15 plays in our body. Background: Inhibitors of other PARP family members, such as PARP1, have been studied because of their role in cancer processes. However, PARP15 remains poorly charac
I denna uppsats utreds de arvsrättsliga skillnaderna mellan efterlevande make respektive sambo och problematiserar dessa utifrån ett äldrerättsligt perspektiv. Förutom att medellivslängden har ökat i Sverige så har dessutom antalet samboförhållanden sedan 1960-talet ökat. 1,5 miljoner svenskar i blandade åldrar antas idag leva som sambo. Oavsett om man valt att leva som gift eller sambo så blir reThe purpose of this thesis is to, from an elder law perspective, study the differences in inheritance law between the surviving spouse and the surviving cohabitant. Apart from the fact that the average life expectancy has increased in Sweden, the number of relationships of unmarried cohabitants has also increased since the 1960s. Approximately 1.5 million Swedish couples in miscellaneous ages are
Many university students feel that their sexual activity is either not sufficient or that it is too high. This leads to dishonesty and discomfort concerning the subject when it is discussed. This can be seen as a sign of conformity. The goal of this quantitative study was to explore a possible correlation between conformity and sexual activity in two university programs at Lund University, Sweden.
Påverkar rovfisk mörtens migrationsbeteende? Migration är ett mycket vanligt fenomen i djurriket. Det är en ofta säsongsbunden händelse med syfte av att till exempel söka efter föda, parningstillfällen eller för att undkomma rovdjur eller någon annan riskfylld miljö. Ibland är det bara vissa individer i en population av migrerande djur som deltar. Detta kallas i litteraturen för partiell migratioPartial migration, defined as when only some individuals within a population migrate whereas others remain as year-round residents, is ubiquitous in the animal kingdom. However, the reasons why some, but not all individuals migrate are not fully understood. Results from multiple recent studies indicate that the propensity to migrate often is flexible and influenced by ecological factors such as fo
By the end of the 1960s there was a growing environmental concern all around the globe. As a part of an answer to this challenge the need was recognized for a reorientation of the education processes towards developing knowledge, attitudes and skills for resolving the issues. This was the birth of the concept of Environmental Education (EE). However, this notion is far from being static as it went
The Swedish implementation of the EU's Data Retention Directive, entailing mandatory retention of electronic communications data concerning all individuals for the purpose of law enforcement, was passed in 2012. In 2014 the directive was ruled invalid by the Court of Justice of the European Union on the basis of its alleged infringements on fundamental rights. Implementations of the directive
Under de senaste decennierna har antalet diagnostiserade cancerfall stadigt ökat. För patienter med den ödesdigra hjärntumören glioblastom har överlevnadsstatistiken dock stått still. Forskare i Lund och Köpenhamn tros nu ha funnit pusselbiten som kan komma att ändra på detta. Cancern är en av de dödligaste sjukdomarna i Sverige och stod för 26 procent av alla dödsfall år 2017. Däremot har man unPurpose: Improvements in mortality rate of glioblastoma patients have been limited during the past decades, due to the tumor’s rapidly growing and infiltrative behavior and resistance to current therapy. Recent findings show that higher brain mean dose strongly correlates with inferior overall survival and that local recurrences mainly occur centrally in previously irradiated regions. This project

The design field is at a determining moment, with socially and environmentally imminent threats in the coming decades. To tackle such complex problems requires extensive and adaptive responses. Design at the intersection of anthropology, sustainability and innovation is the most pressing discussion of our time (Erickson, 2003). A starting point for designers could be to start digging were we st
Träldom var en form av slaveri vilken fanns i Norden fram till 1300-talet. I Sverige minskade träldomen troligen i omfattning under 1200-talet och försvann helt i början av 1300-talet. Det är dock oklart hur länge träldomen har funnits i Sverige och hur utbredd den var före medeltiden på grund av bristen på källor. Träldom förbjöds i Västergötland och Värmlands lagsagor 1335 då Skarastadgan utfärdSlavery existed in the Nordic countries until the fourteenth century. There is some debate regarding how old it is and how common it was. However, it is generally regarded that slavery grew less common in Sweden during the thirteenth century and was abolished during the fourteenth century. Traces of slavery can be found in Swedish medieval laws, the so-called Landskapslagarna. Though nearly all of
The purpose of this investigation was to evaluate the personality questionnaire 30 aspects, which is based on the five-factor model. Our aim was to investigate the properties of the questionnaire through explorative factor analysis and reliability ratings. We also set out to explore the factor structure of the test to decide whether the instrument agreed with the five-factor model or not. The ques
The main purpose of this essay was to find out what motivates immigrants to start their own business. We decided to study the local immigrant-owned pizzarestaurants in Halmstad, Sweden. We choose to conduct a questionnaire and a couple of interviews, which was a complementary to extend our understanding. We wanted to get their view of motivations behind the choice to run their own business. We als
