Vaccines may have non-specific effects as suggested mainly in mortality studies from low-income countries. The objective was to examine the effects of BCG and smallpox vaccinations on subsequent risk of lymphoma and leukaemia in a Danish population experiencing rapid out-phasing of these vaccines. In a background cohort (N=47,622) from the Copenhagen School Health Records Register, cases of leukae
OBJECTIVE: The aim of this study was to evaluate fetal hemoglobin (HbF) and alpha(1)-microglobulin (A1M) in maternal serum as first-trimester biomarkers for preeclampsia (PE). STUDY DESIGN: The design was a case-control study. We included 96 patients in the first trimester of pregnancy (60 with PE and 36 controls). Venous serum samples were analyzed for HbF and total hemoglobin (Hb) by enzyme-link
Robot-assisted general surgery operations are being performed more frequently. This review investigates whether robotic assistance results in significant advantages or disadvantages for the operative treatment of gastro-oesophageal reflux disease and achalasia.
Sweden has set a goal to produce 100% renewable electricity in 2040. In order to accomplish this, a transition towards renewable energy (RE) is necessary. However, the development of RE needs to coexist with other interests of the nation, as RE typically occupies large areas of land or off shore water. This has resulted in conflicts, for instance, between offshore wind power development and nation
Interpreting EEG measurements is of great relevance, both for developing underlying neuroscientific theory and improving existing applications. In this study, two networks with different approaches to time-frequency analysis and feature selection are compared on simulated and real data for semantic and emotional perception. The first network uses the Morlet wavelet transform to achieve adaptable f

As commodities are becoming more popular and accessible assets for speculative and hedging purposes, the limited research regarding risk management for said asset-class justifies further contribution to the deficient output. Many previous studies have highlighted the extraordinary high volatility, with non-linear and clustering characteristics associated with commodities. Hence, incorporating vola
Few studies have been made on challenges and enablers with implementing Stage-Gate processes in mature organizations. The aim with this thesis, is therefore to fill the gaps in knowledge within implementation of Stage-Gate processes and additionally describe the general challenges and enablers with Stage-Gate processes for R&D and innovation projects. PaperCo, a mature international organizati
This Master Thesis has been written at EADS (European Aeronautic Defence and Space Company) Airbus in Bremen.The work contains a description of a few methods when linearising SystemBuild models in MATRIXx. MATRIXx is a tool for matrix manipulations (similar to Matlab) and SystemBuild is a graphical modeling environment (similar to SimuLink). The methods examined are the linearization command “lin”
The purpose of the Master Thesis is, on one hand, to develop a traction control system, integrating and implementing two controllers in the vehicle, each of them previously designed and tested separately, to test them together to evaluate their performance. On the other hand, to develop accurate and well-performing controllers, the data acquisition needs to be precise so parameters and devices nee
In the face of climate change wind energy plays an increasing role in Norway. The construction of new wind farms causes opposition and conflicts with, among others, Sámi reindeer herders who are concerned about losing their pastures. By using Schlosberg’s (2004) environmental justice framework, I explore the justice implications of wind energy with regard to Sámi reindeer husbandry in the case of
A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. To gain a deeper understanding of the catalyst, a surface science study is necessary, but it is impossible to perform
Bakgrund: Psykisk ohälsa bland ungdomar och unga vuxna har ökat och kommer sannolikt att fortsätta öka på sikt. Depression och ångestsyndrom är bland de vanligaste orsakerna till psykisk ohälsa världen över. Arbetsterapeuter besitter en avgörande kompetens inom aktivitet och hälsa. Denna kompetens kan vara behjälplig för ungdomar och unga vuxna med depression och ångestsyndrom. Syfte: Att kartläggBackground: Mental illness among youth and young adults has increased and will likely continue to increase in the long term. Depression and anxiety disorders are among the most common causes of mental illness worldwide. Occupational therapists possess competence in activity and health. This competence can be helpful for adolescents and young adults with depression and anxiety disorders. Aim: To ov
Previously developed methods to evaluate FED and FEC level via combination of CFD and evacuation simulation have been verified by new features of FDS6 and extended to fire cases involving common building materials. The FED levels calculated by the conversion factor [1] based on carbon monoxide are compared with the direct calculation by way of mass fraction of carbon monoxide, hydrogen cyanide and
