System cost reductions and development of standardised plug-and-function systems are some of the most important goals for solar heating technology development. Retrofitting hot water boilers in single-family houses when installing solar collectors has the potential to significantly reduce both material and installation costs. In this study, the TRNSYS simulation models of the retrofitting solar th
The COST 2100 channel model is a geometry based stochastic channel model (GSCM) for multiple-input multiple-output (MIMO) simulations. This paper presents parameterization and validation of the channel model for peer-to-peer communication in the 300 MHz band. Measurements were carried out in outdoor environments for both line-of-sight (LOS) and non line-of-sight (NLOS) scenarios. The COST 2100 cha
Abstract in UndeterminedInside a tunnel, electromagnetic wave propagation differs strongly from the well understood "open-air" situation. The characterization of the tunnel environment is crucial for deploying vehicular communication systems. In this paper we evaluate vehicle-to-vehicle (V2V) radio channel measurements inside a tunnel. We estimate the time-varying root mean square (rms) delay and
Background: Critical needs for treatment trials in gastroesophageal reflux disease (GERD) include assessing response to treatment, evaluating symptom severity, and translation of symptom questionnaires into multiple languages. We evaluated the previously validated Reflux Disease Questionnaire (RDQ) for internal consistency, reliability, responsiveness to change during treatment and the concordance
This Master Thesis was carried out at Ecolean Development AB, which is a subsidiary to Ecolean AB. Light weighted packages have become an alternative to carton packages which is the most common used around the world. The largest markets are Asia and Eastern Europe. Light weight package has low impact environmentally because of its minimal energy consumption during production. The package is filled
The foundation of International Refugee Law was laid down in the early 1950s by the creation of the UNHCR and the Geneva Convention of July 28 1951Relating to the Status of Refugees (hereinafter the Geneva Convention) and its 1967 Protocol Relating to the Status of Refugees. Refugees and asylum seekers are not only protected through the relatively limited refugee law but also through general human
Today, one of the most important questions around the world is that of climate change and the battle against carbon emissions. Wind power has proven to be the most successful option among renewable energy sources, and it is a crucial tool in the race to cut our carbon emissions and to safe security of supply within the EU. Until now, most of the development has occurred onshore, but offshore wind
I Sverige får i dag hälften av befolkningen dricksvatten från vattentäkter som helt saknar eller har ett föråldrat skydd mot föroreningar. För att få bukt med problemet har Naturvårdsverket tagit fram anvisningar i form av tjugo punkter, samt tre tilläggspunkter, för upprättandet av ett vattenskyddsområde runt vattentäkten. Syftet med denna litteraturstudie har vart att jämföra sexton vattenskyddsIn Sweden today, half of the population gets their drinking water from water extraction areas without- or with out-dated protection against contamination. To resolve this problem the swedish government institution, Naturvårdsverket, has written a list, in the form of twenty directives, to help in the establishment of a water protection area around the water collection point. The purpose of this li
The rise and dominance of the corporate form of business organization and its impacts on society and the environment, has lead the concept and practice of Social Responsibility (SR) or Corporate Social Responsibility (CSR) to grow, flourish and spread. This thesis focuses on the assessment of the current CSR status of Swedish commercial vehicle component manufacturer Haldex. The company is going t

Supervisor: Anna Angelin Assessor: Anett Schenk Before starting this research we had the apprehension that the concept of a ” reasonable standard of living” was essential in decision making among the social workers in the field of finan
Background/Purpose
Global competition, an increased focus on market requirements, advances in information and communication technology as well as in international freight systems, are some factors that have caused global companies to review their distribution networks. Upon assessing Ericsson’s distribution network, a need for transit terminals has been acknowledged by the company. Thes
In boreal forest soils, mycelium of mycorrhizal fungi is pivotal for regulating soil carbon (C) cycling and storage. The carbon use efficiency (CUE), a key parameter in C cycling models, can inform on the partitioning of C between microbial biomass, and potential soil storage, and respiration. Here, we test the dependency of mycorrhizal mycelial CUE on stand age and seasonality in managed boreal f
This paper examines how images of unfortunate childhoods are invoked to make sense of psychological problems in adulthood. I use conversation analysis and membership categorization analysis to study a Swedish radio program in which a psychotherapist talks to people about their personal troubles. The findings suggest that, on one hand, the image of an unfortunate childhood was used as an explanator
The effect of age on ICA and thyrogastric antibodies at diagnosis of IDDM was evaluated in 633 consecutively diagnosed Swedish diabetic patients aged 15-34 yr and in 282 volunteers of the same age. ICAs were present in 61% (383 of 633) of the patients and in 2% (5 of 282) of control subjects. When the initial classification was considered, ICAs were detected in 69% (327 of 473) of patients with ID
Human milk fat is a concentrated source of energy and provides essential and long chain polyunsaturated fatty acids. According to previous experiments, human milk fat is partially lost during continuous enteral nutrition. However, these experiments were done over relatively short infusion times, and a complete profile of the lost fatty acids was never measured. Whether this loss happens considerin
Spatial transcriptomics allows for the measurement of RNA abundance at a high spatial resolution, making it possible to systematically link the morphology of cellular neighbourhoods and spatially localized gene expression. Here, we report the development of a deep learning algorithm for the prediction of local gene expression from haematoxylin-and-eosin-stained histopathology images using a new da
Bio-based 5-hydroxymethylfurfural (5-HMF) and its derivatives have attracted enormous attention due to their valuable market potential. Production of pure 5-HMF is challenging owing to the high reactivity of its functional groups and formation of by-products. In this study, an efficient continuous process for 5-HMF production in a biphasic system and its recovery at high yield and selectivity was
We present spatially and spectrally resolved emission from nanowires with a thin radial layer of GaAs embedded in AlGaAs barriers, grown radially around taper-free GaAs cores. The GaAs layers are thin enough to show quantization, and are quantum wells. Due to their shape, they are referred to as quantum well tubes (QWTs). We have investigated three different nominal QWT thicknesses: 1.5, 2.0, and
The standard prognostic marker for multiple myeloma (MM) patients is the revised International Staging System (R-ISS). However, there is room for improvement in guiding treatment. This applies particularly to older patients, in whom the benefit/risk ratio is reduced because of comorbidities and subsequent side effects. We hypothesized that adding gene-expression data to R-ISS would generate a stro
Following mycobacterial entry into macrophages the ESX-1 type VII secretion system promotes phagosomal permeabilization and type I IFN production, key features of tuberculosis pathogenesis. The current model states that the secreted substrate ESAT-6 is required for membrane permeabilization and that a subsequent passive leakage of extracellular bacterial DNA into the host cell cytosol is sensed by
