Do Multinationals Pay Less in Taxes than Domestic Firms? Evidence from the Swedish Manufacturing Sector
There is a strong general concern amongst policymakers worldwide that multinational enterprises engage in far-reaching tax-planning activities. It is generally thought that by using transfer pricing or other techniques to shift profits, multinational enterprises can avoid taxation and thereby erode tax bases. Several attempts have been made to tackle this problem, not least through the OECD/G20 in
Influence of laser mode amplitude and laser mode phase fluctuations on spectral noise in CARS
A model for calculating the noise in nonlinear optical processes arising from (nonquantum) stochastic fluctuations (mode beating) in and between the lasers participating in the nonlinear interaction has been previously developed. Assuming that all individual laser mode phases and laser modes are (statistically) independent (Gaussian statistics) and that the nonlinear interaction can be expressed a
Rotational coherent anti-Stokes Raman spectroscopy (CARS) in nitrogen at high pressures (0.1-44 MPa) : Experimental and modelling results
Pure rotational coherent anti-Stokes Raman scattering (CARS) has for the first time been investigated for pressures up to 44 MPa in nitrogen gas at room temperature. An atomic filter consisting of a heated cell with sodium vapour was successfully applied for suppression of stray light originating from the narrowband CARS pump laser beam. With increasing pressure the rotational CARS spectrum is smo
Physical inactivity during leisure time and irregular meals are associated with functional gastrointestinal complaints in middle-aged and elder subjects
Objectives: Few studies have examined how lifestyle factors affect functional gastrointestinal disorders. The aim of this study was to see if leisure time physical inactivity, dietary habits or body mass index (BMI) were associated with increased risk of functional abdominal pain, functional bloating, functional constipation or functional diarrhea. Methods and materials: This study was based on a
Interacting factors associated with Low antibiotic prescribing for respiratory tract infections in primary health care - A mixed methods study in Sweden
Background: Prescribing of antibiotics for common infections varies widely, and there is no medical explanation. Systematic reviews have highlighted factors that may influence antibiotic prescribing and that this is a complex process. It is unclear how factors interact and how the primary care organization affects diagnostic procedures and antibiotic prescribing. Therefore, we sought to explore an
Myo-inositol changes precede amyloid pathology and relate to APOE genotype in Alzheimer disease
Objective: We aimed to test whether in vivo levels of magnetic resonance spectroscopy (MRS) metabolites myo-inositol (mI), N-acetylaspartate (NAA), and choline are abnormal already during preclinical Alzheimer disease (AD), relating these changes to amyloid or tau pathology, and functional connectivity. Methods: In this cross-sectional multicenter study (a subset of the prospective Swedish BioFIND
Experimental Active-Site Mapping by Fragments - Hot Spots Remote from the Catalytic Center of Endothiapepsin
Successful optimization of a given lead scaffold requires thorough binding-site mapping of the target protein particular in regions remote from the catalytic center where high conservation across protein families is given. We screened a 361-entry fragment library for binding to the aspartic protease endothiapepsin by crystallography. This enzyme is frequently used as surrogate for the design of re
Cellular targets of HAMLET, their role in tumor cell death and therapeutic potential
Protein-lipid complexes have broad and specific effects against cancers of different origins. HAMLET (Human Alpha-lactalbumin Made LEthal to Tumor cells) is a complex of partially unfolded α-lactalbumin and oleic acid that kills a wide range of tumor cells but leaves healthy differentiated cells unaffected. Therapeutic efficacy of HAMLET has been demonstrated in several animal models, without appa
Essays on Firms' Financing and Investment Decisions
This thesis analyses how the capital structures of financial and non-financial firms affect each other and how shocks in the financial sector affect investments in non-financial firms. The thesis consists of three self-contained essays.The first essay provides new evidence on the capital structure determinants of non-financial firms and contributes to the discussion concerning the effect of a regu
A Study on Energy Used to Deliver H.264/AVC and H.265/HEVC Video Content
We propose an end-to-end approach to describe the energy usage of video delivery within a content delivery framework, and use this to investigate the energy usage behavior of two popular coding schemes, namely, H.264/AVC and H.265/HEVC. Our study based on the proposed model is backed up by measurements of encoding and decoding energy usage of a sample video and shows that, from an end-to-end persp
Stray light rejection in rotational coherent anti-Stokes Raman spectroscopy by use of a sodium-seeded flame
A common experimental problem with rotational coherent anti-Stokes Raman spectroscopy (CARS) is undesired spectral interference that is due to stray light from the primary laser beams. Also, for the most developed approach, dual-broadband rotational CARS, practical measurements often suffer from stray light interference from the narrow-band laser, inasmuch as the CARS signal is produced inherently
Soot-visualization strategies using laser techniques - Laser-induced fluorescence in C2 from laser-vaporized soot and laser-induced soot incandescence
Strategies for spatially resolved soot volume-fraction measurements have been investigated in sooting laboratory flames with known soot characteristics. Two techniques were compared: Laser-Induced Fluorescence in C2 from Laser-Vaporized Soot (LIF(C2)LVS), and Laser-Induced Incandescence of soot (LII). The LII signal is the increased temperature radiation from soot particles which have been heated
Application of laser-induced fluorescence and CARS for combustion diagnostics
Laser diagnostic techniques have during the last decade been successfully applied for diagnostics of combustion processes. The main advantages with these techniques are that they are inherently non-intrusive and that spatially as well as temporally resolved information can be achieved. The current paper will exemplify two different laser spectroscopic techniques. Laser-Induced Fluorescence (LIF),
C2 Production and Excitation in Sooting Flames using Visible Laser Radiation : Implications for Diagnostics in Sooting Flames
Swan band emission of C2. which had been produced and excited (d3∏x←a 3∏u, Δ v = 0) by focused, tunable, visible laser radiation, was studied in sooting ethylene flames. The C2signal from the sooting regions of the flames was found to be proportional to the measured volume fractions of soot, indicating laser-vaporized soot to be the source of the signal, and as such it can be used as a diagnostic
High summer temperatures and mortality in Estonia
Background: On-going climate change is predicted to result in a growing number of extreme weather events - such as heat waves - throughout Europe. The effect of high temperatures and heat waves are already having an important impact on public health in terms of increased mortality, but studies from an Estonian setting are almost entirely missing. We investigated mortality in relation to high summe
Prioritizing Surgical Care on National Health Agendas : A Qualitative Case Study of Papua New Guinea, Uganda, and Sierra Leone
Background: Little is known about the social and political factors that influence priority setting for different health services in low- and middle-income countries (LMICs), yet these factors are integral to understanding how national health agendas are established. We investigated factors that facilitate or prevent surgical care from being prioritized in LMICs. Methods and Findings: We undertook
Usefulness of the Sum Absolute QRST Integral to Predict Outcomes in Patients Receiving Cardiac Resynchronization Therapy
Cardiac resynchronization therapy (CRT) reduces mortality and morbidity in selected patients with heart failure (HF), but up to 1/3 of patients are nonresponders. Sum absolute QRST integral (SAI QRST) recently showed association with mechanical response on CRT. However, it is unknown whether SAI QRST is associated with all-cause mortality and HF hospitalizations in patients undergoing CRT. The stu
N-nitrosamines in the southern Swedish rubber industries - exposure, health effects, and immunologic markers
OBJECTIVES: The aim of this study was twofold: (i) to evaluate the air levels of N-nitrosamines in the Swedish rubber industry and (ii) to estimate the risk of symptoms and changed levels of immunologic markers in relation to these levels.METHODS: Using adsorption tubes, we collected samples of N-nitrosamines in the breathing zone of 96 rubber workers and analyzed them with liquid chromatography t
No quick fixes : four interacting constraints to advancing agroecology in Uganda
A century after its inception, agroecology has entered mainstream development debates as a more sustainable alternative to conventional agricultural modernization of relevance not least for improving smallholder agriculture in sub-Saharan Africa. Agroecology is a broad concept considered to have transformative potential, yet as a research field it has often been technology-centred and focused at t
