We collected information on sociodemographic factors, pesticide use, and the presence of respiratory and allergic symptoms during the last 12 months via questionnai
BACKGROUND: Perfluoroalkyl substances (PFAS) have been associated with impaired antibody levels after childhood vaccinations and immunosuppressive effects in animals. However, the in vivo effects of PFAS on antigen specific human T cell responses have not been investigated in adults. In Ronneby, Sweden, the drinking water of one of the water works was previously highly contaminated with primarily
Aim: To explore the meaning of adaptation after visceral transplantation in terms of patient experiences, symptoms, self-efficacy, transplant-specific and mental well-being. Design: A convergent parallel mixed-methods study, consisting of interviews and generic as well as transplant-specific questionnaires. Results were integrated using meta-inference. Methods: The study comprises a population of
Trötta ögon, huvudvärk, för kallt eller för varmt och allmänt lägre prestationsförmåga. Så kan det se ut på ett kontor med dålig ventilation och detta minskar förtjänsten för företaget samtidigt som det för de anställda upplevs påfrestande. Med ett väl dimensionerat, och rätt valt tilluftssystem blir inomhusklimatet avsevärt bättre och de anställda har de bästa förutsättningarna att med glädje pre
Microbial water quality is often assessed with heterotrophic plate counts (HPC) which are not trustworthy and time consuming, and flow cytometry (FCM) with DNA staining by SYBR® Green I (SG) has been suggested as a suitable tool for analyzing the bacterial community in drinking water. This study investigated the existing staining protocol and then applied this protocol to monitoring of slow sand f
Bus lanes are being built as a measure to increase the share of public transport, thereby reducing congestion and environmental impacts. Evaluations are rarely made and the effects of the measures are therefore, in many cases unknown. It is currently unclear whether there are some general correlations between the Swedish cities where bus lanes have been built. This report examines the general tren
Antivirals for HPV infection Human papillomaviruses (HPV) are present in more than 99% of all cervical cancers and HPV-16 is one of the predominant types of HPV infections and account almost for 50% of cervical cancer cases. Although two vaccines are available on the market and showed notable promising in HPV prevention, there are still no available antiviral drugs for HPV infections. In this stu
Fotosyntetiserande växter, alger och bakterier fångar in och omvandlar solenergi till kemisk energi. Själva ljusinfångningen involverar olika pigment, varav de mest kända är de gröna klorofyllmolekylerna som förekommer i olika varianter (varav två varianter kallade klorofyll A respektive B förekommer hos högre växter). De ljusinfångande pigmenten inkluderar även de mer mångtaliga karotenoiderna, ePhotosynthetic organisms harvest and convert light energy into chemical energy and utilize it in their metabolism. The light is captured through pigments called chlorophylls and carotenoids, present in the thylakoid membranes inside the chloroplast. In addition to acting as auxiliary light harvesters, the carotenoids also act as antioxidants by 1) preventing the formation of reactive oxygen specie
När avfall kommer på tal, inte bara inom avfallsbranschen, finns idag ett stort fokus på att minska de totala avfallsmängderna och att öka utsorteringen av återvinningsbart material. Trots det ökar de nationella avfallsmängderna. För att göra arbetet med både avfallsminimering och en ökad utsorteringsgrad så verkningsfullt som möjligt, är det viktigt att veta vad som påverkar avfallsmängderna. SyfWhen waste is on the agenda, not only in the waste industry but in general, there is a high focus on reducing the amount of waste and to increase the amount of sorted recyclable material. Despite this, the total waste amount in Sweden is increasing. To be able to minimize the amount of waste and maximize the waste sorting degree it is important to know the factors that affect the waste stream. The
Den 1 januari 2019 infördes omfattande ändringar i det svenska företagsbeskattningssystemet. Från att tidigare endast begränsat avdrag för ränteutgifter hänförliga till interna lån innebär bolagsreformen att alla ränteutgifter begränsas och principiellt omfattas alla svenska aktiebolag av regelverket. Neutralitetsprincipen uttrycken en målsättning om att den skattskyldiges val mellan olika handlin

This thesis aims at comparing the differences between Chinese welfare system and Swedish welfare system in respects of maternity insurance, parental leave and childcare. The reason comparing welfare system in these specific aspects is because they have intense relations with the mothers’ and children’s benefits. They also influence the mothers’ will of pregnancy. Selecting these two countries as t
Entrepreneurial orientation (EO) can be defined as strategic processes encouraging entrepreneurial actions to support businesses in recognizing and exploiting new opportunities. Previous studies have shown that businesses with higher levels of EO, characterized through actions that are innovative, proactive and risk-affine, perform better than the ones that lack such orientation. Therefore, EO is
Multimodala transporter är frekvent förekommande och viktiga i dagens internationella handel. En multimodal transport innebär kort att gods transporteras från dörr till dörr med hjälp av minst två olika transportsätt under ett kontrakt med en (multimodal) transportör som ensamt ansvarig för kontraktets utförande. Dock är det vanligt att delar av, eller hela, transporten utförs av undertransportöreMultimodal transport is of great practical importance and is widely used in modern international trade. In short, multimodal transport is signified by the moving of cargo from door-to-door by at least two different mods of transport under one single contract with one (multimodal) carrier responsible for the entire carriage. However, it is common that parts of, or the whole carriage is subcontracte
The smallest of things can make a big impact Nanoparticles (NPs) are very small particles that range from 1-200 nanometers. To put this in perspective, envision a football. A NP is approximately as small compared to a football as the football is to the earth. Considering how small these particles are you can imagine that they have unique abilities to travel throughout living systems. The use of t
Demand for plant products has increased in recent years. To produce a vegetable yogurt with good taste and with the right consistency is problematic without the milk protein casein. Product development of a vegetable yoghurt type product was made. Collaboration with Veg of Lund AB was performed on their currently existing products My Foodie blueberries, raspberry and sea buckthorn with a focus on
The railway makes an extensive barrier in the landscape. To lower the impact of this barrier, and to allow people to easily pass it, level crossings are implemented. A level crossing is an intersection in the same plane between railway and road. Here traffic of all sorts meet with railway vehicles, which is why level crossings are one of the most distinct points of conflict in the entire railway s

This thesis opens up the “black box” of business incubation and analyses how this process works in an incubator for cultural and creative ventures in Northern Sweden. The theoretical framework of the rites of passage by Arnold van Gennep and Victor Turner was adopted to guide the analysis. This theory indicates that one can move from one status to the next in a society through the means of differe
The aim of this MSc-project was to investigate whether it is possible to incorporate native cell membrane components from Jurkat T cells into supported lipid bilayers, SLBs, to produce a model membrane system better resembling the native cell membranes in T cells. The procedure of forming native-like SLBs (nSLB) was adapted from an existing protocol and is done through the deposition of hybrid ves
