Lithium abundances are presented for 91 dwarf and subgiant stars in the Galactic bulge. The analysis is based on line synthesis of the 7Li line at 6707 Å in high-resolution spectra obtained during gravitational microlensing events, when the brightnesses of the targets were highly magnified. Our main finding is that bulge stars at sub-solar metallicities that are older than about eight billion year
Decision analysis is often used to help decision makers choose among alternatives, based on the expected utility associated to each alternative as function of its consequences and potential impacts. Environmental impacts are not always among the prioritized concerns of traditional decision making. This has fostered the development of several environmental problems and is nowadays a reason of conce
BACKGROUND: The spinal cord is composed of a large number of cells that interact to allow the organism to function. To perform detail studies of cellular processes involved in spinal cord injury (SCI), one must use repeatable and specific methods to target and injure restricted areas of the spinal cord.NEW METHOD: We propose a robust method to induce SCI in zebrafish by laser light. With a 2-photo
Även om man redan under 1930- och 40 talen förstod att små vattendroppar under vissa förutsättningar kan förbättra släckeffektiviteten för vatten jämfört med större vattendroppar och slutna vattenstrålar, så var det inte förrän på 1990 talet som tekniken med fasta system med ”vattendimma” kommersialiserades. Incitamentet var i första hand det så kallade Montrealprotokollet och branden ombord på pModern, commercial water mist fire protection system technology evolved at the beginning of the 1990s due a need to replace halon fire-extinguishing systems and improve fire safety on passenger ships. This thesis documents the unknown water mist system development work by two Swedish companies during the 1970s and 1980s. It also documents the development of the first international installation rec
The transcription factor SOX2 is a well-established and important stem cell marker. Its role in cancer biology remains unclear, but it has been proposed to also be a marker of cancer stem cells. We investigated the role of SOX2 protein expression in women with high-grade serous ovarian cancer (HGSOC) to determine its potential prognostic and treatment predictive value. We constructed a tissue micr
Different scientific communities produce different kinds of datasets that rely on different data descriptions, approaches, and logical organisations. In such an environment, it is essential to establish a knowledge communication framework that can guarantee some fundamentals, such as an inclusive description and documentation of the interdisciplinary digital resources, their long-term preservation
This paper summarizes the experimental and numerical investigations on an innovative hybrid joint for timber structures. A total of 12 hybrid dowel and bonding steel plate joints divided in four subgroups were investigated. Different parameters such as the presence of self-tapping screws and the surface treatment of the bonding steel plate, were studied. For two subgroups, a vulcanized rubber laye
Objective: The aim of this study was to assess information literacy performance of students doing their master thesis at 5th year the Medical Degree Programme, Lund University, Sweden. The study investigates if there is a difference in performance between library class participants and non-participants. Method: A case-control approach with rubrics assessment was used to assess students’ informati
Determining how electrode structure governs the performance of an electrocatalyst requires techniques capable of probing structure at the atomic scale, often in situ and operando. In recent years, there have been numerous advances in the main experimental techniques for determining the structure of the electrochemical interface. In situ/operando synchrotron surface x-ray diffraction measurements a
Pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension are rare conditions that require complex interventions by multidisciplinary teams. The European Society of Cardiology (ESC)/the European Respiratory Society (ERS) 2015 guidelines included recommendations for pulmonary hypertension (PH) referral centers including minimum number of patients, staff, facilities, and netw
Denna avhandling omfattar en komparativ studie av systemen för domstolsprövning av förvaltningsbeslut enligt svensk, dansk och österrikisk rätt. Framställningen omfattar en rättslig analys av de regler och principer som styr dels när en domstolsprövning av förvaltningsbeslut kan komma till stånd (vilka sakprövningsförutsättningar som gäller), dels vad en sådan prövning omfattar och kan leda till (This thesis contains a comparative study of the systems of judicial review of administrative decisions in Swedish, Danish, and Austrian law. The main aim of the study is to explore how the three legal systems balance certain interests and functions that are related to the phenomenon of judicial review of administrative acts: on the one hand, the principle of effective judicial protection as well a
Objective: To examine the prevalence of dysnatraemias among children admitted for paediatric surgery before and after a change from hypotonic to isotonic intravenous maintenance fluid therapy. Design: Retrospective consecutive time series intervention study. Setting: Paediatric surgery ward at the Children's Hospital in Lund, during a 7-year period, 2010-2017. Patients: All children with a blood s
The problem of equivalence in terms of multistability properties between gene regulatory network models of different dimensionality has been recently addressed by Schittler et al.(2013). The authors in that work proposed construction rules for a high-dimensional dynamical system, when given a low-dimensional dynamical system and the high-dimensional network structure. However, the proof therein wa
Background: Abdominal aortic aneurysm (AAA) and cardiovascular disease are intimately associated, the latter representing the most common cause of death in Sweden. Cardiac complications are held responsible for the majority of perioperative morbidity and mortality in patients undergoing repair of AAA. The importance of preoperative thorough cardiac assessment is therefore obvious. The aim of this
A severe water scarcity challenge is facing Iraq, which is predominantly due to the absence of water management policies, negatively impacting the water quantity and quality provision from the Tigris and Euphrates Rivers. Moreover, these practices have led to the intrusion of the Arabian Gulf salinity wedge into the Shatt Al-Arab River (SAR), which is the main water source for most water treatment
Background: Hypoxic-ischaemic encephalopathy (HIE) is a leading cause of mortality and long-term neurological sequelae, affecting thousands of children worldwide. Current therapies to treat HIE are limited to cooling. Stem cell-based therapies offer a potential therapeutic approach to repair or regenerate injured brain tissue. These preclinical findings have now culminated in ongoing human neonata
