Parasitter og cytokiner i en naturlig populasjon I naturen finner vi utallige eksempler på arter som har spesialisert seg på å utnytte andre arter for næring, trygghet og overlevelse. Denne spesialiseringen kalles parasitisme, og har ofte en kostnad for verten i form av redusert helse og livskvalitet. Hos däggdjur, er en stor parasittgruppe innvollsparasitter. nematoder som lever i tarmene og sugAbstract In nature, the coexistence of parasites and hosts has been an important factor in evolution of the immune system, which can be found in all plants and animals. As parasitic infections are by definition affect overall fitness of the host, it is important for the host to be able to counteract the detrimental effects of infections. To ensure this, signaling molecules, known as cytokines, e

This research is to investigate and analyse an identity formation of an immigrant group in a host country. The author would like to understand immigrants’ identities as a diaspora community, by focusing on Turkish community in Sweden and identification process in terms of personal and collective identities, using the diaspora as a ground theory with semi-structured individual interviews in which n

Plastic production is only increasing, and it‟s not showing any signs of slowing down. Microplastics are particles smaller than 5 mm, either produced intentionally, or created from items being withered into small particles. Microplastic contamination in marine environments is higher closer to cities, and most of the plastic litter eventually ends up in the oceans. Microplastics have been found in

In the last decades, scholars, managers and consultants have shown increased interest in identifying the characteristics of high-performance organizations. Searching for ways to improve organizational performance and respond to a growing demand for quality products and services in a rapidly changing environment, this subject is of special interest of managers in both public and private organizatio

I väpnade konflikter så väl som i fredstid har förekomsten av våldtäkter och dess utbredda straffrihet fördömts av FN och förbud mot detta har konsekvent erkänts inom det internationella samfundet. Denna ståndpunkt är dock en för- hållandevis ny strävan. Den sena reaktionen på de krigsrelaterade våldtäk- terna är delvis en konsekvens av att våldtäkt historiskt präglats av myter. My- ter så som attRape and other forms of sexual violence committed with impunity during armed conflicts as well as peacetime has been condemned by the UN and the international community. However, this position is a relatively new. The late reaction to the war-related rapes is partly a consequence of the fact that rape has historically been the subject of myths. Myths such as that rapes represent an inevitable resu

Drönare används idag inom en rad områden. Projektet H24LEO, som drivs av Trafikflygarhögskolan vid Lunds Universitet (TFHS) och är finansierat av Vinnova, har som mål att utveckla och demonstrera en drönare driven av ett hybridiserat vätgasbränslecell-system baserat på PEM-tekniken. Denna drönare har som tilltänkt syfte att kunna erbjuda understöd i så kallade Search and Rescure-uppdrag hos SjöfarUnmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce

Ett samboförhållande är ett förhållande mellan två personer som stadigvarande bor tillsammans i ett parförhållande och har gemensamt hushåll. Med parförhållande avses en förbindelse vari som regel ingår sexuellt samliv. Sexuellt samliv är alltså en förutsättning för att ett förhållande ska kunna konstituera ett samboförhållande. Men vad innebär detta krav egentligen? Att kräva att ett förhållandeA cohabiting relationship is a relationship between two people who permanently live together as a couple and have a joint household. To live as a couple means to live in a relationship in which a sex life is usually a part of. A sex life is thus a prerequisite for a relationship to be able to constitute a cohabiting relationship. But what does this requirement really mean? Having a sex life as a

Delningsekonomi är ett växande fenomen i samhället. Kortfattat handlar delningsekonomi om att använda underutnyttjade resurser bättre genom att dela. Att dela ytor kan innebära en mer effektiv användning av befintliga byggnader vilket potentiellt kan minska behovet av nyproduktion. På svenska fastighetsmarknaden finns däremot viss problematik som hindrar en ökad delning av ytor. Problematiken beröThe sharing economy is a growing phenomenon in society. Simply described, the sharing economy is about using underutilized resources better through sharing. Sharing space can mean a more efficient use of existing buildings, which potentially can reduce the need for new buildings. In the Swedish real estate market, there are certain problems that prevent an increased sharing of space. The problems

The goal of this master thesis was to identify an alternative to shaft encoders as means of achieving accurate motor velocity and position control for sliding door systems. While the company had previously explored methods like using backEMF, this thesis investigates counting voltage ripples during the commutation process in a brushed DC motor. During commutation, one or two pairs of commutator se

The authors of this paper identified a gap in the debate revolving around innovation during a crisis and recognized the importance of exploring whether being highly innovative is universally desirable across all sectors during times of crisis. While previous research has emphasized the positive impact of innovation on performance, it is essential to investigate the negative impact of innovation an

In 1988 Hills proposed that stars can gain velocities above 500 km s−1 if they are in a stellar binary which gets disrupted by a super massive black hole (SMBH). One of the stars would get trapped in an elliptical orbit around the SMBH while the other gets ejected and obtains a relatively high velocity. Normally stars within galaxies have low peculiar velocities but stars ejected with velocities o

Glioblastoma (GBM) is the most aggressive type of primary brain tumours in adults and accounts for 49.1% of the cases. Most of the cases are recorded in elderly patients, but GBM affects people of all age groups. Till date no cure has been found. Previous data has suggested that pericytes might influence tumour invasion by interacting with tumour cells by the secretion of or interaction with extra

Body weight is a predictor of clopidogrel response. However, no prospective studies have compared pharmacodynamic (PD) and pharmacokinetic (PK) data based on body weight. We compared PD and PK effects of clopidogrel 75 mg in low body weight (LBW, <60 kg) and higher body weight (HBW, ≥60 kg) patients with stable coronary artery disease. LBW (n = 34, 56.4 ± 3.7 kg) and HBW (n = 38, 84.7 ± 14.9 kg) a

Background and purpose In Sweden, surgery for knee osteoarthritis (OA) in patients younger than 55 years of age has doubled during the last 10 years. We evaluated the use of 3 surgical alternatives: high tibial osteotomy (HTO), unicompartmental arthroplasty (UKA), and total knee arthroplasty (TKA). We also examined the outcome, expressed by rate of revision. Methods The numbers of all procedures d
