Sammanfattning Avregleringen av den finansiella marknaden har skapat förutsättningar för alternativa marknadsplatser. Företag kan i dag välja att notera sig på icke traditionella börser som inte är knutna till en fysisk handelsplats. För att skapa förtroende och långsiktighet för dessa virtuella marknadsplatser krävs det att vikt läggs vid relationen till kunderna. En del i detta är att ta hänsyn
Purpose: The inappropriate irrigation is accelerating the soil salinization in western irrigation districts of China. The amelioration of salinized land must be based on large amount of water content and salinity data. Plastic coated TDR has been designed to measure water content accurately in highly saline soil, but the soil bulk electrical conductivity cannot be measured due to the coated materi
Objectives: To describe the process and outcomes of using a new evidence base to develop scientific guidelines that specify the type and minimum dose of exercise necessary to improve fitness and cardiometabolic health in adults with spinal cord injury (SCI). Setting: International. Methods: Using Appraisal of Guidelines, Research and Evaluation (AGREE) II reporting criteria, steps included (a) det
Objectives: To analyse the section of Disclosure UK that pertains to healthcare professionals (HCPs) in order to provide insight into the database’s structure and content and suggest ways to improve its transparency.Design and participants; Cohort study of drug companies and HCPs in the 2015 and 2016 versions of Disclosure UK.Results: Companies report transfers of value (ToVs) to named HCPs or, wh
The European Academy of Dermatology and Venereology (EADV) Task Forces (TFs) on Quality of Life (QoL) and Patient Oriented Outcomes, Melanoma and Non-Melanoma Skin Cancer (NMSC) present a review of the literature and position statement on health-related (HR) QoL assessment in skin cancer patients. A literature search was carried out to identify publications since 1980 that included information abo
The development of Pt(IV) anticancer prodrugs to overcome the detrimental side effects of Pt(II)-based anticancer drugs is of current interest. The kinetics and reaction mechanisms of the reductive activation of the carboplatin Pt(IV) prodrug cis,trans-[Pt(cbdca)(NH3)2Cl2] (cbdca = cyclobutane-1,1-dicarboxylate) by the major small-molecule reductants in human plasma were analyzed in this work. The
Context. Possible main formation sites of fluorine in the Universe include asymptotic giant branch (AGB) stars, the v-process in Type II supernova, and/or Wolf-Rayet stars. The importance of the Wolf-Rayet stars has theoretically been questioned and they are probably not needed in modeling the chemical evolution of fluorine in the solar neighborhood. It has, however, been suggested that Wolf-Rayet
Popular Abstract in Swedish De ökande kraven på högre datahastigheter inom trådlös kommunikation ställer allt högre krav på både radiosändare och mottagare, då dessa behöver utnyttja fler frekvensband med större bandbredd vid högre frekvenser. Fokus i denna avhandling ligger på högfrekvensdelen av radiomottagaren, som består av lågbrusförstärkare, blandare, och oscillatorer vid mikrovågsfrekvenserThe increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. Tra
In this document, a large number of mathematical models describing various physical, biological and chemical processes in a wastewater treatment plant are presented. In most cases, the models are fairly simple as they are inteded for steady-state simulations based on yearly averages of the influent wastewater charteristics. The combination of models forms a software tool namned URWARE (URban WAter
Popular Abstract in Swedish Allt fler ungdomar i vårt land, liksom i många andra länder, lever i vardagen med mer än en kultur. En femtedel av eleverna i den svenska skolan är antingen själva födda i ett annat land eller har minst en förälder med utländsk bakgrund. För många av dessa barn och ungdomar har därför inte samhällets dominerande kultur funnits med från början av deras liv. Bekantskapen The present study is based on interviews with 22 youth and young adults. The perspective is phenomenological, since my aim has been to analyse and describe the everyday world as it presents itself to these young people. A process begins in the encounter with the majority culture and the emphasis is on how they think about events and experiences along the road to a more complex life-world. The proc
In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase. However, when biofuels are burned or
Electronic commerce (E-commerce) is one of the issues that are expected to influence the various logistics and supply chain processes/operations including: production, packaging, warehousing, transportation, etc. Consequently, the environmental implications of E-commerce are of concern and interest. In this regard, there are some pilot studies, but they are unable to deliver conclusions or general
In ST-elevation myocardial infarction (STEMI), thrombus material is often present in partial or total coronary occlusion of the coronary vessel. However, prior to the thrombus aspiration during ST-Segment Elevation Myocardial Infarction in Scandinavia (TASTE) trial, it remained unclear whether routine thrombus aspiration during percutaneous coronary intervention (PCI) treatment of STEMI would resu
We study here deterministic broadcasting in geometric radio networks (GRN) whose nodes have complete knowledge of the network. Nodes of a GRN are deployed in the Euclidean plane (R 2) and each of them can transmit within some range r assigned to it. We adopt model in which ranges of nodes are non-uniform and they are drawn from the predefined interval 0 ≤ r min ≤ r max . All our results are in the
With advances in data acquisition and processing methods, spectral inversion of time domain (TD) induced polarization (IP) data is becoming more common. Geological interpretation of inverted spectral parameters, for instance Cole–Cole parameters, often relies on results from systematic laboratory measurements. These are most often carried out with frequency domain (FD) systems on sandstone samplesWith advances in data acquisition and processing methods, spectral inversion of time domain (TD) induced polarization (IP) data is becoming more common.

There is today a need of better prediction of part geometry regarding industrial products by simulations. There is a need for better prediction of material inflow, stresses and strains and final geometry. One way to solve this could be by using a more advanced friction model. Today a zero order friction model (Coulomb friction) is normally used. By using a friction model of higher order the fricti
Digital images are an intuitive way to capture, store and analyse organismal phenotypes. Many biologists are taking images to collect high-dimensional phenotypic information from specimens to investigate complex ecological, evolutionary and developmental phenomena, such as relationships between trait diversity and ecosystem function, multivariate natural selection or developmental plasticity. As a
Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method
During the last decades, coherent anti-Stokes Raman spectroscopy (CARS) has been an important tool in combustion research. The focus of this thesis is the improvement of the capability of the pure rotational CARS (RCARS) technique for this type of applications. The technique is used to measure temperatures and relative species concentrations in the gas phase and thermometry is performed by fitting
