Kejsarsnitt, utebliven amning och antibiotika ökar risken för sjukdomar Hur många av dina vänner har någon form utav allergi? Pollen, nötter? Trots att vår sjukvård är bättre än någonsin har vi en stor ökning av sjukdomar i samhället, bland annat allergier. Varför är det så? Kliande ögon, snuva, nästäppa… Låter det bekant? Var tredje svensk har någon form utav allergi, vilka kan vara allt från lBackground and Aim The aim was to investigate the effects of four early life factors – delivery mode, feeding method, probiotics, and antibiotics – on disease development in childhood. This was done by conducting a structured literature review. Methods A literature search was performed in PubMed, Google Scholar and ReadCube Papers for studies published between January 2000 and October 2022. For e

There are currently increasing concerns about escalating crude oil prices, depleted petroleum resources, and environmental damages caused by plastics. In light of this, bio-based and biodegradable materials, such as polyhydroxyalkanoates (PHAs), have gained global attention from industry and academia as sustainable alternatives to petroleum-based materials. Poly-hydroxybutyrate (PHB) is the simple

Strömmande vatten påverkar broar över vattendrag huvudsakligen genom: (1) hydrodynamiska krafter med direkt effekt på konstruktionen och (2) lokal erosion kring bropleare och sidostöd, inkluderat erosion på grund av flödeskontraktion. Utformning och dimensionering av broar i Sverige med avseende på direkt flödespåverkan och lokal erosion är relativt förenklad och täcker inte alla aspekter av problThe role of bridges in the transportation network has become increasingly important as they ensure the smooth and safe passage of people and goods across rivers and other bodies of water. Flowing water impacts bridges over rivers primarily in two ways: (1) Hydrodynamic forces that directly impact the structure and (2) scouring at the pier and abutment, including contraction scour. The design princ

Under de senaste åren har gröna obligationer blivit ett populärt finansieringsalternativ bland många svenska fastighetsbolag. Obligationerna är finansiella instrument och fungerar som räntebärande skuldebrev med en förutbestämd löptid. Investerarna erhåller därmed avkastning i form av ränta och kan samtidigt vara säkra på att det investerade kapitalet används för klimat- och miljövänliga investeriIn recent years, green bonds have become a popular financing option among many Swedish real estate companies. Bonds are financial instruments and function as interest-bearing debentures with a predetermined term. The investors receive a return on capital in the form of interest and can at the same time be sure that the invested capital is used for climate and environmentally friendly investments b

Bakgrund: När COVID-19 pandemin bröt ut i Sverige i början av 2020 vidtog regering ett stort antal beslut och åtgärder beträffande skolorna. Periodvis digital undervisning för högstadieskolor, minskad fysisk aktivitet och social isolering ledde till ett ökat lidande med oro, stress och ångest hos en del barn. Skolsköterskan ställdes inför helt nya utmaningar i sitt hälsofrämjande och förebyggande Background: When the COVID-19 pandemic broke out in Sweden at the beginning of 2020, the government took a large number of decisions and measures regarding the schools. Periodic digital teaching for junior high schools, reduced physical activity and social isolation led to increased suffering with worry, stress and anxiety in some children. The school nurse was faced with completely new challenges

Det finns olika typer av så kallade artificiella neurala nätverk som används till olika saker. En av dessa kallas för konvolutionella neurala nätverk och används till att bearbeta bilder. Denna typ av artificiella neurala nätverk används bland annat för klassificering av bilder och för att styra självkörande bilar. I den här uppsatsen används ett konvolutionellt neuralt nätverk för att försöka förIn this thesis, a convolutional neural network is used to model the behaviour of individual vehicles on a stretch of the U.S. 101 highway during rush hour. This model is then extended to model the collective behaviour of all vehicles on the stretch of road and a 15 minute simulation is carried out. Using an initial vehicle layout, images displaying the position of nearby vehicles and information o

Ett avgörande av Högsta domstolen kan endast angripas genom extraordinära rättsmedel. När Högsta domstolen får in en ansökan om resning eller klagan över domvilla i ett mål avgjort av Högsta domstolen är det som utgångspunkt andra justitieråd i domstolen än de som avgjorde det aktuella målet som prövar huruvida grund finns för att bevilja en sådan ansökan eller klagan. Dessa justitieråd kan då ha A decision by the Supreme Court can only be challenged through extraordinary remedies. When the Supreme Court receives an application for relief due to a substantive defect or a complaint on the grounds of grave procedural errors the general rule is that other justices of the Supreme Court than those who decided the case in question review whether there are grounds for granting such an application

This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. The transistors used in this project are nanowire MOSFET transistors developed by the Division of Electromagnetics and Nanoelectronics, LTH, L

In this thesis we consider multiplicative integrals and derivatives on functions on the positive numbers, the logarithmic Riemann surface and the punctured complex numbers. Additive structures on the real and complex numbers are related to their multiplicative counterparts on the positive numbers and the logarithmic Riemann surface by defining exponential transition functors. We use a lift-project

The employment effects of expansionary fiscal policy have been well documented in the literature. Interestingly, however, limited attention has been paid to the gender dimension. Across countries, significant gaps in female and male employment still remain. This, together with the risk of hysteresis, makes it central to examine how expansionary fiscal policies affect female and male employment and

Syftet med studien var att undersöka vilken påverkan en helgkurs i autentiskt relaterande hade på kvaliteten i deltagarnas relationer. Relationskvalitet mättes i två kontexter: Mellan kursdeltagarna respektive i deras befintliga relationer utanför kurskontexten. Syftet var att undersöka om kursen påverkade relationskvaliteten mellan deltagarna och om deltagarna kunde dra nytta av nya färdigheter fThe purpose of this study was to investigate the impact a weekend course in authentic relating had on different aspects of the quality of the participants' relationships. The relationship quality was measured in two contexts: Between the course participants and in their existing relationships outside the course context. The aim was to investigate whether the course affected the quality of rela

There is extensive research on creativity and innovation, as well as the question of whether UGC and social media platforms foster creativity or dumb down culture. There is however a gap in research on how creative and innovative UGC is. The purpose of this study is therefore to investigate the creative motivations behind creating UGC and whether the UGC on TikTok is applicable to creative and inn

The goal of this article is to propose, through the use of GIS software, an interdisciplinary method to suggest new touristic flows after the Covid-19 pandemic. Specifically, the aim is to identify those sites of cultural and landscape interest that are little known but with great artistic, cultural, historical and environmental value that could give new vigour to the tourism sector. In the first

In this master thesis nanowires have been simulated to study the effect of spatial imperfections in the nanowires. This spatial imper- fection took the form of potential fluctuations in the conduction band across the wire. To achieve this, scripts were written in MATLAB to simulate the nanodevices by applying the non-equilibrium Green’s function (NEGF) method. To verify the simulations, multiple q

CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. At CERN, a range of magnetic coils are utilized, many of which are custom-made and located in various research facilities

Cultural and creative industries have been prominent topics of academic and policymaking discussions over the past two decades. However, existing literature has predominantly concentrated on urban and metropolitan regions, neglecting peripheral regions. By identifying this research gap, this project aimed to contribute to our understanding of cultural and creative industries in peripheral regions,

The thesis explores an already developed symmetry adapted representation of a two-body interaction with the main goal of extending the method to also include three-body interactions. The method considers a space of shifted one dimensional Gaussian particle densities which are used, together with their corresponding Hartree potentials, to define the respective collective subspaces in which the inte

Digitalization has in recent years transformed the music industry and how people consume music. Simultaneously, the social media app TikTok has emerged as a major player in marketing, using its unique algorithmic structure and user-generated content to become a powerful marketing tool for musicians and record labels alike. Therefore, this paper investigates the effect of TikTok on music consumptio
