Transition metal coordination compounds have a rich photochemistry and are interesting candidates as both light harvesters (photosensitizers) and catalysts in photocatalytic systems. Knowledge of electronic and molecular structure of excited states of photosensitizers and intermediates of catalysts is a key topic for rational design of systems for artificial photosynthesis. We describe recent adva
In the second chapter there is a description of corruption today. First I will provide a definition of corruption. Many definitions exist, but the common criteria in these definitions are abuse of power for private gain to the detriment of public interest. After explaining the theoretical definition I will describe corruption in practice through providing different forms of corruption. Public sect
Background: Today, many companies use a cost-based and sometimes competition-based pricing approach. Since academia agrees that value based pricing is superior for creating profit, the problem is not in identifying an ideal pricing strategy, but to understand and facilitate the transformation process towards value-based pricing. Only a limited amount of research has so far been put on understandin
Within the scope of this project, investigations were made into the possibility of replacing Electron Beam Lithography (EBL) with NanoImprint Lithography (NIL) for creating arrays of gold dots on substrates, with the aim of nanowire growth. The attempted nano wires grown were aimed to be of use in the field of biotechnology. The main focus and aim of this project has been to perfect a fabrication
Fast-neutron/gamma-ray pulse-shape discrimination has been performed for the organic liquid scintillators NE 213A and EJ 305 using a time-of-flight based neutron-tagging technique and waveform digitization on an event-by-event basis. Gamma-ray sources and a Geant4-based simulation were used to calibrate the scintillation-light yield. The difference in pulse shape for the neutron and gamma-ray even
Let P be a set of n points in the Euclidean plane and let O be the origin point in the plane. In the k-tour cover problem (called frequently the capacitated vehicle routing problem), the goal is to minimize the total length of tours that cover all points in P, such that each tour starts and ends in O and covers at most k points from P. The k-tour cover problem is known to be NP-hard. It is also kn
A pioneer study of the previously unknown delta C-13 chemostratigraphy in the Ordovician/Silurian boundary interval in eastern Iowa and northeastern Illinois resulted in the discovery of the Hirnantian Isotope Carbon Excursion (HICE). The presence of this major isotope excursion in the Mosalem Formation in Iowa and the Wilhelmi Formation in Illinois, which indicates that the excursion interval in
Approaches integrating interdisciplinary perspectives are necessary to address current and future health and environmental challenges. Many policy initiatives have embraced more holistic approaches to tackle these challenges, e.g., the One Health concept, the Farm to Fork (F2F), Biodiversity and Chemical strategies within the European Green Deal and the global Sustainable Development Goals (SDGs).
“Han talte de om som en hjälte ”examines the use of parody and satire in the Swedish comedy series S*M*A*S*H (1990) and Pistvakt (1998–2000) as well as the feature film Pistvakt – En albinovästern från de vita vidderna (2005). By analyzing how the series illustrates performative masculinity from the definitions of Judith Butler in Gender Trouble (1990), conclusions on wheth
We present a wall-to-wall map of dominant tree species in Swedish forests accompanied by pixel-level uncertainty estimates. The tree species classification is based on spatiotemporal metrics derived from Sentinel-1 and Sentinel-2 satellite data, combined with field observations from the Swedish National Forest Inventory and auxiliary data on geomorphometry and canopy height. We apply an extreme g
Mali and Somalia have both suffered determined Islamist-inspired insurgencies, and in both African Union-led peace operations have been a central pillar in political and security stabilization efforts. Despite challenges in transferring lessons between unique situations, the AMISOM experience can offer some useful lessons for Mali. We have identified several themes that helped to drive success for
A large number of rachopharmaceuticals labelled with C-11 (half-time 0.340 h) are being developed for positron emission tomographic studies of different types of receptor in the human brain. For most of these agents, the available biokinetic data are insufficient to construct realistic compound-specific biokinetic models for calculating the internal radiation dose delivered to persons undergoing i
The output factor for a therapy photon beam is defined as the dose per monitor unit relative to the dose per monitor unit in a reference field. Convolution models for photon dose calculations yield the dose in units normalized to the incident energy fluence with phantom scatter intrinsically modeled. Output factors calculated with the convolution method as the dose per unit energy fluence relative
Serglycin (SG) is a proteoglycan expressed by hematopoietic cells and is constitutively secreted by multiple myeloma (MM) cells. SG participates in the regulation of various inflammatory events. We found that SG secreted by human MM cell lines inhibits both the classical and lectin pathways of complement, without influencing alternative pathway activity. The inhibitory effect of SG is due to direc
Summary. We assessed the reliability and construct validity of the Compatible MRI scale for evaluation of elbows, and compared the diagnostic performance of MRI and radiographs for assessment of these joints. Twenty-nine MR examinations of elbows from 27 boys with haemophilia A and B [age range, 5–17 years (mean, 11.5)] were independently read by four blinded radiologists on two occasions. Three c
