Förhöjda halter koldioxid! Hur dåligt är det egentligen? Inledning: Flera forskare har i egna studier kommit fram till att koldioxid har en negativ effekt på hälsa och prestation. Vår atmosfär är en av faktorerna som gör att vi kan leva här på jorden. Atmosfären består till stor del av kväve (78%) och syre (21%) och lite över en procent andra gaser. Bland dessa gaser förekommer koldioxid. KoldioThis study’s purpose was to try and study whether Carbon Dioxide in indoor environments (schools and offices) affect performance and health in students and office workers in terms of mental effects and Sick Building Syndrome. This study was executed as a literary study where eight different scientific articles were analysed and compared to see if their results are comparable with each other and sh

There are many possible sources for anthropological research, however, this thesis examines tourists' comments on internet forums. In particular, tourist comments on the TripAdvisor page of the Kumari Chowk in Kathmandu, Nepal will be examined. These reviews will be divided into trends in order to consider the reason why tourist decides to visit the Kumari Chowk. This will be done in the light

Många groddjur har minskande populationstrender både lokalt och globalt. Inventeringar av groddjur är en viktig del av arbetet för att få mer information om deras utbredning för att kunna skydda groddjuren och deras miljöer. Detta kan ha positiva effekter även på andra djur och växter eftersom groddjur är bra indikatorer på rika miljöer. Genom sitt vattenupptag via huden är groddjuren extremt käns

Conflict-related sexual violence should not be regarded just a symptom of war or evidence of its violent excess. It is criminalised as a violation of international law, as a war crime, a crime against humanity and, in some cases, as a component of genocide. It brings overwhelming social, psychological and economic consequences to survivors, families, communities and nation states. Conflict-related

Given a pollen data set from Europe over a time period, the aim is to reconstruct the past land cover by interpolating from the pollen data values to a continuous map. The data is on compositional form with three vegetation categories; coniferous forest, broadleaved forest and open land. Reconstruction will be based on a Gaussian Markov random field with separable spatio-temporal structure for the

This thesis describes attempts at estimating the uncertainty of the 2-metre temperature forecast error from a probabilistic point of view, utilizing Bayesian neural networks. Bayesian neural networks are a type of machine-learning algorithms used to find patterns in data and make probabilistic predictions. Multiple fields of output data from the ECMWF IFS global model, along with temperature measu

Since carbon-emitting energy sources are the largest contributor to global warming and climate change, this present paper attempts to contribute to the current debate in energy-growth nexus in the literature. Focusing on the case of Turkey, it seeks to find out whether or not switching to a low-carbon path will be beneficial for this fastest-growing OECD economy by investigating the relationship b

Splicing in cancer Proteins are functional molecules responsible for every biochemical process that sustain living organisms. However, how genetic information is expanded to generate amazing diversity of proteins during development and in cancer remains still mostly unresolved. The mechanism we have to account for this diversity is known as splicing. Information-containing RNA molecules, copies

Zinc oxide nanoparticles (ZnO NPs) are often used in sunscreen and other cosmetic products with sun protection. They are also candidate to be used for various biological applications such as drug delivery, or in material science in for example solar cells. ZnO NPs are produced as liquid suspensions but also as dry powders, which increases the risk of exposure via the air. In this master’s thesis,

En funktion som har fått mycket uppmärksamhet bland matematiker är den så kallade Riemanns zeta-funktion, som definieras med hjälp av en summa av oändligt antal termer, en så kallad serie: zeta(s) = 1 + 1/2^s + 1/3^s + 1/4^s + ... Här är s=a+ib en komplex variabel med en reell del a och en imaginär del, där i har egenskapen i^2=-1. Värdet på den här serien kommer givetvis bero på vilket värde pWe establish the central convergence properties of ordinary Dirichlet series, including the classical result by Bohr, providing uniform convergence of the series where it has a bounded analytic continuation. We also derive a lower bound for the supremum of Dirichlet polynomials using Kronecker's theorem, of which we see one proof. With this knowledge and some probability theory we can follow t

A new probiotic for the cure of diabetes Metabolic diseases such as obesity and type 2 diabetes are becoming increasingly common worldwide and are major causes of disability and death indicating an urgent need for interventions. Emerging evidence points to a central role of gut microbiota in metabolism, for example blood glucose metabolism and appetite regulation. Furthermore, intervention with

Mexico has experienced the dramatic escalation of crime and violence in an organized form since the 1990s, and have also witnessed the highest number of homicides in the last ten years. It has adversely affected the national security, economic growth and social development with an especially detrimental effect on youth in Mexico. This study examines the direct and indirect impacts of drug trade-re

The endowment effect, that people tend to value goods higher if owning them than if not, conflicts central economic principles. A new theory explains this price disparity by uncertain sellers’ and buyers’ strategic reliance on opposite borders of a spectrum of possible utilities of a good. Through a review of concurrent theories, this paper highlights the superiority of the new uncertain utilities

The purpose of this qualitative secondary analysis is to study how victims of sex trafficking are illustrated in previous research. 16 peer reviewed articles have been analysed based on a hermeneutic approach. The results of previous research are consistent: The society has a narrow view of victims, and a more complex, intersectional understanding of the victimhood is required. The victims` storie

Ultra high magnetic field (UHF) MR-systems is an interesting research area, the systems offer images with higher spatial resolution than its lower field counterpart. One of the disadvantages with UHF MR is that they lead to a worsened B1-field homogenity, a homogentity essential for the creation of MR-images. In the project an 8 independent channel transmit system is charachterised. The transmit s
