Hålla tarmbakterier i schack hos unga möss Efter födseln exponeras ett spädbarn för den yttre miljön för första gången. Detta innebär exponering för ett stort antal bakterier och virus. Spädbarn är mer benägna att bli infekterade av bakterier och virus än vuxna. Hos vuxna kan antikroppen Immunoglobulin A (IgA) hjälpa till att hålla bakterier och virus i schack genom att omsluta dem och agera som The period after birth, when an infant is initially exposed to vast amounts of environmental and microbial antigens, sets the stage for proper immune system development ensuing lifelong immunity. Simultaneous to this first-time exposure, the nursing mother provides immune protection via antibodies in the breast milk. Secretory Immunoglobulin A, as provided by the mother or produced intrinsically i

Tillgång och Effektfrågan – Biogasens Roll i det Gröna Norrbotten Allt fler nyfikna ögon riktas mot Norrland i takt med att den nordligaste landsänden ångar på framåt i utvecklingen mot fossilfria industrier; kommande år planeras miljardinvesteringar i fossilfria tekniker i region Norrbotten, en satsning som kallas den gröna omställningen. Men för att kunna förse etableringarna och samhället medGreat investments are planned in the north of Sweden the coming years, not the least in the county of Norrbotten where the projects collectively are referred to as the green transition due to the focus on fossil-free techniques. But to be able to secure a sustainable energy supply and reach the goal set by the member states of the European Union of a carbon dioxide neutral union in 2050 the produc

The historic urban area of Lisbon emerged during the Middle Ages and was the origin of the development of a rather small neighbourhood, Mouraria. Not only did it count as the centre of the capital, but because of Lisbon being the metropolis of the Portuguese empire, Mouraria is now home to a diverse group of people, whose culture influences its special characteristics to this day. Its medieval str

Vem tycker inte det är mysigt att sitta framför sin kamin, eldstad eller grill? Något som är gemensamt är att samtliga innefattar eldning av biomassa. Eldning av biomassa gör vi av många anledningar. Det kan vara allt från trivseleldning till uppvärmning och elförsörjning. Eldning för många kan vara att få möjligheten att laga mat, varför man eldar ser väldigt annorlunda ut i olika delar av världeBlack carbon (BC) is produced during incomplete combustion of Biomass and fossil fuels. BC and other carbonaceous pollutants have characteristics that affect the climate, environment, and human health. Historically, BC emissions have been measured and monitored in the atmosphere, and BC emissions to the air are quite well documented. Deposition in water and sediments has been less studied but is i

Osteoarthritis (OA) is a chronic degenerative joint disease, linked to age, weight and joint overload. Typical symptoms include joint pain, loss of mobility and joint stiffness. The past two decades the amount of people suffering from OA has increased, and with the current trend of increasing age and weight it is expected to further increase. It is known that knee OA is correlated with the degener

Vattenkraft är den dominerande källan till elektricitet i Sverige, med ett bidrag på 45% av den nationella produktionen. Samtidigt som vattenkraften är avgörande för utfasningen av fossila bränslen och för klimatmålen, är dess miljöpåverkan på den biologiska mångfalden i sötvatten oroande. I denna fallstudie av ett vattenkraftverk i Helge å, var syftet att hitta ett lämpligt flöde för reproduktionHydropower is the dominant source of electricity in Sweden, constituting 45% of the national supply. While pivotal for decarbonization and climate goals, its environmental impact on freshwater biodiversity is concerning. In this case study of a hydropower plant in Helge River, Sweden, the aim was to find a flow suitable for trout (Salmo trutta) and salmon (Salmo salar) reproduction. A terrain mode

Bakgrund: Trauma orsakar livshotande skador och står för nästan åtta procent av alla dödsfall i världen. Det initiala omhändertagandet av traumapatienter ställer krav på att snabbt identifiera, prioritera och behandla befintliga skador. Ett välfungerande traumateam resulterar i en snabbare handläggning vilket förbättrar patientens chanser till överlevnad och minskar risken för komplikationer och f

The aim of this study is to examine idyllic romanticism and pastoral ideals in Swedish children’s literature from two distinct periods of history: the turn of the 19th and 20th centuries, and the 21st century. During the turn of the 19th and 20th centuries, Sweden underwent a radical societal change from an agricultural society to an industrial one. As a response to these changes, there was an inc

Outdoor commercial furniture, particularly tables, often appears to lack well- designed products that address many concerns, including not only functionality and ergonomics but also aesthetic appeal. This study aims to investigate whether this perception reflects an actual problem and explore potential solutions. The purpose of this research is to explore the challenges associated with meeting th

This project is aiming towards designing to extend the lifespan of children’s belongings to reduce excessive owning and over consumption amongst parents. Today, there is an issue of parents of small children needing to own many of the same products that they often need to replace and exchange as the child grows older. It affects both the environment and the personal economy of the parents. The re

This study establishes itself within the Social Accounting literature, particularly in the Corporate Social Responsibility (CSR) string in an effort to develop the knowledge of the current Swedish market, regarding gender equality. The objective of this thesis is to offer a thorough examination of the condition of sustainability reporting on gender equality across Swedish state-owned businesses.

Climate change is one of the most significant challenges that building sector is confronting. For example, Climate change and associated extreme events are posing a significant challenge for the building sector. Buildings should be prepared to withstand the climate changes and extreme weather that will happen in the future. Designing buildings based solely on past or average weather conditions, wh

"Wasserstadt - a place of coexistence" Global challenges such as climate change, resource scarcity, population growth, and migration will inevitably change the way we live. Cities are conglomerates of many and, thus, are often perceived as a threat to wildlife and plant life. But what if we harnessed the potential of cities as conglomerates of people, hubs of innovation, and sustainable

Desk lamps were originally designed for reading and craftsmanship. However, with the increasing prevalence of com- puter-based work and the rise of remote and hybrid work arrangements due to the COVID-19 pandemic, our needs for lighting have evolved. This project aimed to create a versatile desk lamp suitable for both traditional tasks like reading and writing, as well as modern computer

Ektomycorrhiza-svampar (ECM) bildar symbiotiska relationer med träd genom att ansluta till rötterna, och bidrar till växters tillväxt genom att anskaffa näring från marken i utbyte mot kolhydrater från växten. Skogsbruksmetoden kalhygge kan negativt påverka ECM genom att ta bort dess födokälla samt skapa ogynnsamma markförhållanden vilket direkt minskar diversiteten av ECM. Detta arbete syftar tilEctomycorrhizal fungi (ECM) form symbiotic relationships with trees by connecting to the roots, procuring soil nutrients in exchange for carbohydrates, and are an important contributor to plant growth. The forestry practice of clearcutting can be detrimental to the ECM community by removing its source of energy and creating unfavorable soil conditions, acutely reducing ECM diversity. This paper ai

For many machines, safety requires the constant presence of an operator, with the risk of damage or danger if the operator is unintentionally absent. Dead man’s switches (DMS) are commonly used to halt operations if this absence is detected, often relying on physical elements like leashes or buttons. However, these solutions can hinder operator convenience and equipment aesthetics. For devices wit

Bakgrund: Akut smärta är en subjektiv upplevelse och därmed svårt för sjuksköterskan att bedöma och smärtlindra.
