Search for transiting exoplanets in globular clusters

Vi hittar planeter ̈överallt vi tittar i Vintergatan. De ser olika ut var man ̈an kollar. Men det finns några platser där planeter verkar vara obefintliga: i klotformiga stjärnhopar. Dessa innehåller hundratusentals stjärnor som, på grund av gravitation emellan dem, hålls ihop och bildar ett stjärnsystem som sträcker sig över hundratals ljusår i diameter. Än så länge har bara en exoplanet hittats This project consists of a transit search in the Messier 3 Globular cluster with the goal to assess the difficulties of observing planetary transits in globular clusters. M3 was observed for a short period of time and by performing PSF fitting, flux measurements could be done to extract light curves of the 290 stars that are included in this project. To determine the stellar type, an HR-diagram wa

Adverse events associated with microsurgial treatment for ruptured intracerebral aneurysms : A prospective nationwide study on subarachnoid haemorrhage in Sweden

Background Adverse events (AEs) or complications may arise secondary to the treatment of aneurysmal subarachnoid haemorrhage (SAH). The aim of this study was to identify AEs associated with microsurgical occlusion of ruptured aneurysms, as well as to analyse their risk factors and impact on functional outcome. Methods Patients with aneurysmal SAH admitted to the neurosurgical centres in Sweden wer

Plasma phosphorylated tau 217 in preclinical Alzheimer's disease

An accurate blood test for Alzheimer's disease that is sensitive to preclinical proteinopathy and cognitive decline has clear implications for early detection and secondary prevention. We assessed the performance of plasma phosphorylated tau 217 (pTau217) against brain PET markers of amyloid [[11C]-labelled Pittsburgh compound B (PiB)] and tau ([18F]MK-6240) and its utility for predicting longitud

Development, Validation, and Clinical Utility of a Six-gene Signature to Predict Aggressive Prostate Cancer

Background: Molecular signatures in prostate cancer (PCa) tissue can provide useful prognostic information to improve the understanding of a patient's risk of harbouring aggressive disease. Objective: To develop and validate a gene signature that adds independent prognostic information to clinical parameters for better treatment decisions and patient management. Design, setting, and participants:

Latent heterogeneity of muscle-invasive bladder cancer in patient characteristics and survival : A population-based nation-wide study in the Bladder Cancer Data Base Sweden (BladderBaSe)

Background: Patients with muscle-invasive bladder cancer (MIBC) constitute a heterogenous group in terms of patient and tumour characteristics (‘case-mix’) and prognosis. The aim of the current study was to investigate whether differences in survival could be used to separate MIBC patients into separate classes using a recently developed latent class regression method for survival analysis with co

Climate and forest properties explain wildfire impact on microbial community and nutrient mobilization in boreal soil

The boreal landscape stores an estimated 40% of the earth's carbon (C) found in terrestrial vegetation and soils, with a large portion collected in thick organic soil layers. These ground stores are subject to substantial removals due to the centurial return of wildfire, which has strong impacts on the soil microbial community and nutrient cycling, which in turn can control ecosystem recovery patt

The barriers of circular public procurement for ICTs

Offentlig upphandling är en inköpsprocess av nyttjas av offentliga verksamheter såsom myndigheter och kommuner. Årligen spenderar Sverige ca 800 miljarder kronor via offentliga upphandlingar, vilket har en stor inverkan på miljön då dessa kontrakt ofta följer den linjära ekonomiska modellen, slit- och släng samhället. Begreppen cirkularitet och cirkulär ekonomi är relativt nya koncept som har de sThe EU procured for roughly 202000 MEUR (14% of the EU GDP) during 2021 in the public sector. The majority of these contracts are traditional, linear business model purchases. The EU has been developing several strategies, guidelines, and policies for sustainable purchasing, with Circular Public Procurement for a Circular Economy (CE) being one of them, but the implementation rate is low. Electron

Integrating eco-evolutionary dynamics into matrix population models for structured populations : Discrete and continuous frameworks

State-structured populations are ubiquitous in biology, from the age-structure of animal societies to the life cycles of parasitic species. Understanding how this structure contributes to eco-evolutionary dynamics is critical not only for fundamental understanding but also for conservation and treatment purposes. Although some methods have been developed in the literature for modelling eco-evoluti

Oxidative Depolymerization of Kraft Lignin to Aromatics Over Bimetallic V–Cu/ZrO2 Catalysts

Zirconia-supported vanadium–copper catalysts (VCux:yZr) were used for the oxidative depolymerization of softwood LignoBoost Kraft lignin (LB). Various VCux:yZr catalysts were prepared (x:y = 0:1, 1:4, 1:2, 3:4, 1:1, and 1:0) by incipient wetness impregnation, and reactions were performed in alkaline water at 150 °C under an O2 pressure of 5 bar for 10 min. 1H–13C HSQC NMR spectroscopy was used for

Resisting the epistemic argument for compatibilism

In this paper, we clarify, unpack, and ultimately resist what is perhaps the most prominent argument for the compatibility of free will and determinism: the epistemic argument for compatibilism. We focus on one such argument as articulated by David Lewis: (i) we know we are free, (ii) for all we know everything is predetermined, (iii) if we know we are free but for all we know everything is predet
