3D nano-tomography using coherent X-rays

X-rays allow to non-destructively investigate biological, chemical or physical processes at thenano-scale. Their high penetration depth in matter allows to investigate samples even in-side sample environments, which would be difficult with complementary methods such astransmission electron microscopy (TEM). The microscopy technique ptychography has beenestablished in X-ray imaging in recent years.X-rays allow to non-destructively investigate biological, chemical or physical processes at the nano-scale.

The Struggles of Light Bound in Matter : Modelling Optical Excitations in Nanostructures

This thesis addresses three different topics on the interaction between light and matter in open quantum systems. The first topic concerns two-dimensional spectroscopy and the spectral contributions from different nonlinear action signals with a focus on how to differentiate between them. The second topic concerns the thermalization of excited electrons in hot-carrier solar cells with a focus on h

Electronic correlations at paramagnetic (001) and (110) NiO surfaces : Charge-transfer and Mott-Hubbard-type gaps at the surface and subsurface of (110) NiO

We explore the interplay of electron-electron correlations and surface effects in the prototypical correlated insulating material, NiO. In particular, we compute the electronic structure, magnetic properties, and surface energies of the (001) and (110) surfaces of paramagnetic NiO using a fully charge self-consistent DFT+ dynamical mean-field theory method. Our results reveal a complex interplay b

Neuronal Replacement in Stem Cell Therapy for Stroke : Filling the Gap

Stem cell therapy using human skin-derived neural precursors holds much promise for the treatment of stroke patients. Two main mechanisms have been proposed to give rise to the improved recovery in animal models of stroke after transplantation of these cells. First, the so called by-stander effect, which could modulate the environment during early phases after brain tissue damage, resulting in mod

Patient satisfaction and loyalty in Japanese primary care : a cross-sectional study

Background: This study aimed to explore associations between various elements of primary care, patient satisfaction, and loyalty. Methods: This cross-sectional study used a modified version of the Primary Care Assessment Tool (PCAT), which was adapted for Japan. We distributed the PCAT questionnaire to patients aged 20 years or older at five rural primary care centres in Japan. We confirmed the va

Mobile research labs to explore nature-based solutions in Japanese cities : - a way to bridge disciplinary divides?

The mobile research lab is an emerging research methodology increasingly applied in urban studies to investigate phenomena like places, infrastructures, nature and inhabitants of cities. This essay critically explores this relatively new methodology, also known as ‘mobile labs’, as part of in-situ research for a two-year research project supported by the International Fellowship Program of the JapThe mobile research lab is an emerging research methodology increasingly applied in urban studies to investigate phenomena like places, infrastructures, nature and inhabitants of cities.

Performance analysis of daily global solar radiation models in peru by regression analysis

Solar radiation (Rs) is one of the main parameters controlling the energy balance at the Earth’s surface and plays a major role in evapotranspiration and plant growth, snow melting, and environmental studies. This work aimed at evaluating the performance of seven empirical models in estimating daily solar radiation over 1990–2004 (calibration) and 2004–2010 (validation) at 13 Peruvian meteorologic

Compositional and Interfacial Engineering Yield High-Performance and Stable p-i-n Perovskite Solar Cells and Mini-Modules

Through the optimization of the perovskite precursor composition and interfaces to selective contacts, we achieved a p-i-n-type perovskite solar cell (PSC) with a 22.3% power conversion efficiency (PCE). This is a new performance record for a PSC with an absorber bandgap of 1.63 eV. We demonstrate that the high device performance originates from a synergy between (1) an improved perovskite absorbe

Preventable fractions of cancer incidence attributable to 7-years weight gain in the Norwegian Women and Cancer (NOWAC) study

There is a lack of tangible measures for directed public health action to halt the increase in weight and cancer. We estimated the fraction and preventable cases of all and major body fatness-related cancers attributable to 7-years weight gain (≥ 2 kg). We assessed validated self-reported anthropometrics from 44,114 women aged 34–49 years at the enrolment in 1991–1992 and from a second questionnai

Magnetically induced transition in the spectrum of Sr iv

Observations and studies of what we call magnetic induced transitions have arguably re-opened a whole new area of atomic spectroscopy. There are transitions from upper levels that are sensitive to externally applied magnetic fields, such as those in tokamaks and the solar corona. So far only two types of ionic systems have been confirmed as leading to magnetic induced transitions, namely Ne-like A

A Resourcification Manifesto: Understanding the Social Process of Resources Becoming Resources

In times of major global interconnectedness and environmental change, the pressure to identify, create, and exploit new resources is certain to intensify. Given that there are unavoidable trade-offs, conflicts, and arenas for violence involved when increasingly more material and immaterial things are turned into resources, we call for explicit research on the very process – a process that we label

Erytrocyttransfusion till kritiskt sjuka kan vara farligare än anemi

Anemia is common in critically ill patients. Some patients benefit from erythrocyte transfusion, but transfusions are also associated with complications. Randomized controlled trials in critically ill patients have demonstrated that a restrictive transfusion strategy seems safe. This review is an overview of some of the largest studies of erythrocyte transfusions in intensive care.

A longitudinal investigation of cognitive functioning and its relationship to symptom severity and academic functioning in treatment seeking youth with ADHD.

BackgroundChildren with ADHD tend to present with poorer cognitive functioning leaving them more vulnerable to a range of negative outcomes. To date, only a handful of longitudinal studies have examined the stability of Wechsler composite scores in children and adolescents with ADHD, and none of them used a more recent version of the Wechsler Intelligence Scales for Children (WISC), than the WISC-

"Det hade ju aldrig hänt annars" : Om kvinnor, klass och droger

Olika typer av sinnesförändrande substanser har blivit allt fler och vanligare under de senaste 500 åren, och användningen i nutidens konsumtionskulturer fortsätter att öka. Den illegala droganvändningen i Sverige ligger på historiskt höga nivåer. Vissa lagliga preparat, såsom kaffe och alkohol, syns överallt medan läkemedel och illegala droger vanligtvis hålls dolda. Denna etnologiska avhandling

The Hcci Combustion Process in a Single Cycle-High-Speed Fuel Tracer Lif and Chemiluminescence Imaging

The Homogeneous Charge Compression Ignition (HCCI) combustion progress has been characterized by means of high- speed fuel tracer Planar Laser-Induced Fluorescence (PLIF) combined with simultaneous chemiluminescence imaging. Imaging has been conducted using a high-speed laser and detector system. The system can acquire a sequence of eight images within less than one crank angle. The engine was run

Cell-Free DNA Promotes Thrombin Autolysis and Generation of Thrombin-Derived C-Terminal Fragments

Cell-free DNA (cfDNA) is the major structural component of neutrophil extracellular traps (NETs), an innate immune response to infection. Antimicrobial proteins and peptides bound to cfDNA play a critical role in the bactericidal property of NETs. Recent studies have shown that NETs have procoagulant activity, wherein cfDNA triggers thrombin generation through activation of the intrinsic pathway o
