Herein is reported an efficient catalytic system for the direct synthesis of styrene carbonate from styrene and CO2. The preparation and characterization of the catalyst using FTIR, TEM, EDX, XPS, and PXRD is presented. The catalyst comprised of nano-silver modified polyoxometalates (Agx/POM) and n-tetra butyl ammonium bromide (TBAB) was employed in the oxidative carboxylation of styrene with CO2
Background: Current systemic therapies for metastatic pancreatic ductal adenocarcinoma are associated with poor outcomes with a 5-year overall survival rate under 5%. We aimed to assess the safety and antitumour activity of mitazalimab, a human CD40 agonistic IgG1 antibody, with modified FOLFIRINOX (mFOLFIRINOX; fluorouracil, leucovorin, oxaliplatin, and irinotecan), in chemotherapy-naive patients
This paper discusses the role of mathematics in physics teaching and learning. The intention and strength of science is to describe what happens in the realworld by organizing explanations through theories and theoretical models. It has been widely suggested that learning in science is influenced by views about the nature of scientific knowledge. Furthermore, mathematics is an inherent part of the
This paper describes and discusses the development of mobile exergames for children with cerebral palsy. The design process was built on co-design, and resulted in three activity games, two augmented reality (AR) games and one GPS based game. The resulting activity games were evaluated by 8 per-sons with cerebral palsy (CP). To complement this evaluation, the games have been evaluated against exis
We demonstrate that exceptional points exist in fully transparent, optically "effectively" biaxial, anisotropic micro-cavities, fabricated using an uniaxial cavity material with its axis inclined to the Bragg mirror growth direction. This is similar to the existence of singular (optic) axes in absorbing biaxial crystals, but the lack of time reversal symmetry is mediated by the mode broadening, i.
Importance: Recent studies have questioned the presumed low-risk status of patients with asymptomatic nonsevere aortic stenosis (AS). Whether annual N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements are useful for risk assessment is unknown. Objective: To assess the association of annual NT-proBNP measurements with clinical outcomes in patients with nonsevere AS. Design, Setting, a
Objective To evaluate which factors are the most strongly related to self-perceived health among older men and describe the shape of the association between the related factors and self-perceived health using machine learning.Design and setting This is a cross-sectional study within the population-based VAScular and Chronic Obstructive Lung disease study (VASCOL) conducted in southern Sweden in 20
Under de senaste 150 åren har det svenska landskapet genomgått mycket stora förändringar. Det har lett till förlust av livsmiljöer för många arter och har haft långtgående konsekvenser för vår inhemska fauna och flora. Många arter har minskat dramatiskt och i vissa fall helt försvunnit.När en art väl har börjat minska finns det många faktorer som kan förstärka den negativa trenden. En individrik p
Background: Exposure and Response Prevention (ERP) is a form of behavioural therapy for tics; however, its effectiveness remains uncertain. We aimed to evaluate the effectiveness of internet-delivered, therapist-supported, and parent-assisted ERP for treatment of tics in children and young people with Tourette syndrome or chronic tic disorder. Methods: This multicentre, parallel group, single-blin
In this article I call for an awareness of the mobile commons– the informal support that exists among migrating people, NGOs, and activists – in relation to the realization of family reunification. Taking its point of departure in a concrete case of family reunification for young unaccompanied children, the article seeks to expose how the traditional legal notion of the liberal subject fails to pr
Background: The apolipoprotein E (APOE) ε4 allele is associated with higher cholesterol levels, and an increased risk of developing Alzheimer’s disease (AD) and amyloid-related imaging abnormalities after initiation of amyloid-modifying therapies. A worse cognitive response to cholinesterase inhibitor (ChEI) treatment and longitudinal outcome in APOE ε4-carriers has been observed. Based on these c
Epidemics and pandemics are associated with a variety of life-threatening conditions and have serious effects on physical as well as mental wellbeing. The Covid-19 pandemic raised the same difficulties for public and private sectors including schools, businesses, healthcare sectors, etc. The disease, which originated in Wuhan, China in December 2019, has ravaged nearly every country in the world.
Popular Abstract in Swedish Avhandlingen handlar om hur fett (lipider) i kosten bryts ner och transporteras i blodet för att slutligen antingen användas som energi, byggstenar i cellväggarna eller lagras i fettväven. I den här avhandlingen kan man också läsa om hur man kan modifiera fetter med hjälp av speciella proteiner: enzymer för att förbättra näringsinnehållet och dess fysikaliska egenskaperAn important indicator of the metabolic capacity of humans is the ability to regulate plasma triacylglycerol levels and to clear triacylglycerol-rich lipoproteins (TRLs) from the circulation after a meal. This is crucial since most of the day is spent in the postprandial state. High concentrations and long circulation times of TRL remnants may be detrimental since these are considered to be highly
Importance: Long-term follow-up after transcatheter aortic valve replacement (TAVR) is of interest given that longitudinal data on mortality and durability of transcatheter heart valves are limited. The REPRISE III (Repositionable Percutaneous Replacement of Stenotic Aortic Valve Through Implantation of Lotus Valve System-Randomized Clinical Evaluation) randomized clinical trial compared the mecha
Background: Current evidence supports the use of intravenous thrombolysis with alteplase in patients with wake-up stroke selected with MRI or perfusion imaging and is recommended in clinical guidelines. However, access to advanced imaging techniques is often scarce. We aimed to determine whether thrombolytic treatment with intravenous tenecteplase given within 4·5 h of awakening improves functiona
Flimmer, eller nærmere bestemt tidslig lys modulation (TLM), er igen blevet et problem i forbindelse med indførelse af LED-basret belysningsteknologi. TLM, dvs. variationer i lysintensiteten over tid, kan have negativ effekt på menneskers sundhed, og forårsage irritation, hovedpine, overanstrengelse af øjne og migræne. Udover denne unødvendige lidelse, som flimmer kan bevirke hos enkeltpersoner, s
IMPORTANCE: The clinical utility of stress cardiovascular magnetic resonance imaging (CMR) in stable chest pain is still debated, and the low-risk period for adverse cardiovascular (CV) events after a negative test result is unknown.OBJECTIVE: To provide contemporary quantitative data synthesis of the diagnostic accuracy and prognostic value of stress CMR in stable chest pain.DATA SOURCES: PubMed
In industries like high-tech and automotive, increasingly more of the product value delivered to the customer is based on a combination of hardware (HW) and software (SW), where SW handles much of the differentiation of capacity and features. The “logistics process” of SW, especially when it merges with HW along the process, has so far been little studied but a problem noticed is the difficulties
