Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter. Plotting these stars as [C/O] vs [O/H], it is revealed
This thesis is trying to identify and give solutions for the problems occurring in polyurethane sport surfaces in Iraq where the climate is extremely warm and dusty. One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the s
Detta arbete handlar om en behandlingsteknik för hudterapi där lågenergetiska elektroner utnyttjas för strålbehandling där patienten står eller sitter på en roterande plattform. För att behandlingen skall få ett lyckat resultat krävs en viss stråldos (den absorberade energin per massenhet) till patientens hud. För att kontrollera att dosen är rätt används normalt mätningar med olika detektorer. DeBackground and purpose: This study refers to a rotational radiotherapy technique for the treatment of mycosis fungoides. Patients are irradiated by a high dose-rate low-energy electron beam while they stand on a rotating platform. This report presents a first effort to use the Geant4 simulation program to calculate the relation between the stationary and rotational depth dose distributions in an e
The characteristics of an Elekta amorphous silicon (a-Si) electronic portal imaging device (EPID) in response to a 6 MV photon beam generated without a flattening filter, an unflattened beam, have been determined. The characteristics were then compared to those for a conventional photon beam generated with a flattening filter in the beam, a flattened beam, in order to determine the suitability of
Digitalization is shaping the discipline and practice of marketing. Not only does digitalization shape how we shop and consume everything from music to food and mobility services (Cochoy, Hagberg, McIntyre, & Sörum, 2017; Fuentes, Hagberg, & Kjellberg, 2019; Guyader, 2018; Schneider & Eli, 2022), but it has also fundamentally transformed the practices of marketing. Digitalization has c
Forests are crucial for biodiversity, climate stability, and human well-being, yet rising pressures from climate change and conventional forestry practices threaten their resilience and sustainability. Approximately 30% of global forests are managed intensively, often as monoculture plantations, compromising biodiversity conservation, carbon sequestration, and ecosystem stability. Here, we propose
The concept of integrated risk management (IRM) has developed as a response to more interconnected and complex contexts. To investigate how the concept is used and what is meant with integration in the scientific literature, a research profiling was carried out across all kinds of risk management applications. 1094 publications from scientific journals, conference proceedings, and books were inclu
Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,
Mitochondria were isolated from fresh beetroots (Beta vulgaris L. cvs Rubria and Nina) by differential centrifugation followed by Percoll gradient centrifugation. These purified mitochondria oxidized external NADH, although relatively slowly (20-40 versus 100-120 nanomoles oxygen per minute times milligram protein for NADH and succinate oxidation, respectively), with respiratory control ratios of
Objective: To investigate the influence of cardiovascular risk factors, including fasting plasma glucose (FPG), on the association between electrocardiographic (ECG) and echocardiographic left ventricular hypertrophy (LVH) in an elderly population. Methods: We tested cross-sectional associations between electrocardiographic and echocardiographic LVH, defining LVH according to the Sokolow-Lyon volt
Air pollution is one of the major environmental problems in the industrial and populated cities. Predictive mapping of urban air pollution and sharing the generated maps with the public and city officials have positive impacts on society and environment. This article presents a solution based on distributed processing concepts to generate predictive map of air pollution for the next 24 hours. Apac
The study aims to establish the effectiveness of the Danish destination certification scheme – Destination 21. In order to accomplish this, an analytical framework, based upon current tourism and development theory, was constructed against which the scheme was tested. The analytical framework consists from three analyses examining the schemes framework, substance and applicability. It was found th
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into lignocellulosic biorefineries they can become a keystone in a future bioeconomy. In order to achieve this, pulp mills have to close their loops and focus on the optimal utilisa
The term bibliotherapy is well known in several scientific fields as well as among practitioners in the US and in the UK, but in Sweden there seems to be a more modest use of the term as well as presence of practical bibliotherapeutic activity. On the other hand, some of the effects of reading that are commonly associated with bibliotherapy in the scientific literature seems to be similar to the e
