BACKGROUND: There is an increasing interest in cognitive and functional outcomes in the respective stages of Alzheimer's disease (AD) and in novel therapies particularly for the milder phases of AD. Our aim was to describe and compare various aspects of disease progression in patients with mild versus moderate AD in routine clinical practice of cholinesterase inhibitor (ChEI) therapy. METHODS: Thi

The goal of this Master Thesis is to help Tetra Pak with the current problems related with the creasing units. The creasing unit is set with different configurations depending on which package is wanted to be manufactured. The unit is provided with different modules and each module is moved by means a gear transmission. The different packages require different gears setups that could affect the qu

The purpose of this thesis is to develop a theoretical framework that enables a company to design an appropriate channel strategy, to handle communication between the company and its end customers. Methodology: The approach for this master thesis can be described as a combination of an exploratory and problem solving study. It started with a literature study, and the knowledge and inspiration led

Since the demands for energy efficient buildings becomes higher and higher it is interesting to look at how we use our energy inside the buildings. Approximately 87% of all energy used inside a house is used for heat, a good way to lower our energy use would therefore be to lower the amount of energy needed for heat. Today there are several different types of heating systems, some regarded more en

Produktion av en nanotrådssolcell För att ta itu med miljöpåverkan från växthusgaser krävs en övergång till förnyelsebara energikällor. Ett exempel på en sådan källa är nanotrådssolceller. I mitt examensarbete har jag undersökt hur nanotrådar kan arrangeras på sådant sätt som krävs för att kunna omvandla solljuset till elektricitet. Global uppvärmning är ett hot som till stor del orsakas av utslThe demand for cheaper and more efficient solar cells is high. One way to decrease cost of material, while maintaining a high degree of efficiency, is to take advantage of nanomaterials. A thin film containing pn-junction nanowires can convert light with an efficiency comparable to traditional planar cells, while using a fraction of the material, and thus reduce costs. At the company Sol Voltaics

We report the discovery and characterization of two sub-Saturns from the Transiting Exoplanet Survey Satellite (TESS) using high- resolution spectroscopic observations from the MaHPS spectrograph at the Wendelstein Observatory and the SOPHIE spectrograph at the Haute-Provence Observatory. Combining photometry from TESS, KeplerCam, LCOGT, and MuSCAT2, along with the radial velocity measurements fro

Patients with non-obstructive hypertrophic cardiomyopathy (HCM) exhibit myocardial changes which may cause flow inefficiencies not detectable on echocardiogram. We investigated whether left ventricular (LV) kinetic energy (KE) and hemodynamic forces (HDF) on 4D-flow cardiovascular magnetic resonance (CMR) can provide more sensitive measures of flow in non-obstructive HCM.Methods and resultsNinety

BACKGROUND: Patients undergoing hepato-pancreato-biliary surgery are typically preoperatively assessed using the American Society of Anesthesiologists (ASA) classification, which is also used for case-mix adjustment when comparing centre outcomes. Studies determining the inter-rater variability of the ASA classification within hepato-pancreato-biliary surgery are currently lacking.METHODS: An inte

Background: Stroke and acute myocardial infarction (AMI) rank among the leading causes of mortality. Physical activity and exercise are recommended as part of rehabilitation after AMI to prevent cardiovascular events, but the importance for stroke prevention has not been investigated using population-based data. Objectives: To determine associations between participation in exercise-based cardiac

This study aimed to obtain high-resolution 3D isotropic turbo spin-echo (TSE) wrist MRI acquisitions at 7T, with and without fat suppression, facilitated by compressed-sensing (CS) acceleration. In 16 healthy subjects, fat-suppressed (FS) and nonfat-suppressed (NFS) TSE wrist images were obtained. The protocol consisted of a SENSE-accelerated scan, with an isotropic voxel size of 0.45 mm and acqui

BACKGROUND: Platelet transfusions are frequent in the Intensive Care Unit (ICU), either as prophylaxis against bleeding complications or as treatment for bleeding. The European Society of Intensive Care Medicine guidelines for ICU patients generally recommend not using prophylactic platelet transfusions unless the platelet count falls below 10 × 10 9 cells/L in non-bleeding patients and make no re

Background: Guidance on managing acute mesenteric ischaemia (AMI) is largely based on expert opinion and retrospective studies pooling different subtypes of AMI. In clinical practice, management strategy is often selected based on the patient’s severity of illness, whereas randomized controlled trials or even adjusted analyses comparing different strategies are rarely available. We aimed to perfor

The rise in prevalence and severity of obesity and related diseases imposes increasing costs on society. The objective of this thesis is to discuss and estimate the possible effects of a so-called fat tax as a tool for minimizing these costs. Two alternatives for differentiation of the value-added tax (VAT) on food are compared. The first alternative is an increase of the VAT levied on food contai

Pleiotropic effects of spices on health, particularly on glucose metabolism and energy regulation, deserve further clinical investigation into their efficacy. The aim of the current study was to evaluate whether consumption of a black pepper-based beverage (BPB) preload containing 20 mg gallic acid equivalent (GAE) would exert any effect on postprandial glycaemia, appetite sensations, gut hormones

The alternating between dry and wet seasons and the consecutive microbial responses to soil water content in semiarid ecosystems has significant consequences on nitrogen exchanges with the atmosphere. Three field campaigns were carried out in a semi arid sahelian rangeland in Dahra (Ferlo, Senegal), two at the beginning of the wet season in July 2012 and July 2013, and the third one in November 20

Background: Apolipoprotein M (apoM) is a 25-kDa apolipoprotein present in 5% of high-density lipoprotein (HDL) particles. It is suggested to be anti-atherogenic and to play a key role in sustaining endothelial barrier integrity. SLE patients have increased cardiovascular disease risk, and we aimed to investigate if apoM levels reflect endothelial function in SLE. Since apoM plasma levels decrease

Objectives: To investigate the preoperative prognostic value of molecular subtypes in relation to clinical information, histopathological findings, and molecular markers for patients with bladder cancer treated with radical cystectomy. Patients and methods: After standard preoperative staging, a population-based cohort of 519 patients underwent radical cystectomy between 2006 and 2011. Following
