Petrochemical producers both rely upon and generate some of the most problematic substances in the current age of socioecological crisis: fossil fuels and plastics. With mounting calls to cap fossil fuel extraction as well as plastics production, the industry appears to be caught between a rock and a hard place. Nonetheless, betting on continuously increasing global plastic demand, petrochemical p
Context The context of this research is software process improvement (SPI) success factors for small and medium Web companies. Objective The primary objective of this paper is to propose a theoretical framework of SPI success factors for small and medium Web companies. Method The theoretical framework presented in this study aggregated the results of three previous research phases by applying prin
Symptoms of obsessive–compulsive disorder are related to atypical sensory processing, particularly sensory over-responsivity, in both children and adults. In adults, obsessive–compulsive symptoms are also associated with the attenuation of access to the internal state and compensatory reliance on proxies for these states, including fixed rules and rituals. We aimed to examine the associations betw
Epithelioid and spindle cell hemangioma was initially described in 1999 in a series of primary bone tumors and was subsequently suggested by some to represent a variant of epithelioid hemangioma. Here, we studied 18 epithelioid and spindle cell hemangiomas. Nine patients (50%) were male. Age at presentation ranged from 12 to 78 years (median: 38.5 y). Nine patients (50%) had tumor(s) limited to bo
Lakes are important natural resources and carbon gas emitters and are undergoing rapid changes worldwide in response to climate change and human activities. A detailed global characterization of lakes and their long-term dynamics does not exist, which is however crucial for evaluating the associated impacts on water availability and carbon emissions. Here, we map 3.4 million lakes on a global scal
The epoxide hydrolase StEH1 catalyzes the hydrolysis of trans-methylstyrene oxide to 1-phenyl-propane-1,2-diol. The (S,S)-epoxide is exclusively transformed into the (1R,2S)-diol, while hydrolysis of the (R,R)-epoxide results in a mixture of product enantiomers. In order to understand the differences in the stereoconfigurations of the products, the reactions were studied kinetically during both th
Centrifugal compressors are widely used in turbocharged powertrains for Heavy-Duty applications. The volute of the centrifugal compressors is generally of the overhung type. The design of volutes is often neglected, and the shape of the volute is dictated by the packaging requirements of the engine. However, with the advent of Hydrogen-based propulsion systems, the efficiency of all the components
This project evaluates the impact of interior insulation on external walls in three Swedish heritage buildings. Field measurements and hygrothermal simulations were conducted to assess available solutions. Measurements of temperature and relative humidity were taken both indoors and outdoors, as well as on the exterior and interior surfaces of the walls. The accuracy of simulation standards for in
Aims/hypothesis: Low birthweight (LBW) is associated with younger age, less obesity and more hypertension among people recently diagnosed with type 2 diabetes, as well as increased cardiovascular morbidity and mortality risk. It is not known whether LBW is associated with an increased risk of incident chronic kidney disease (CKD) among people with a type 2 diabetes diagnosis. Methods: Original mid
Purpose: There is a growing literature on the importance of cultural adaptation of research-supported social work interventions. Few studies have however offered systematic methods for the a priori assessment of intervention fit in a new context. The current study explores the use of measurement invariance analyses to help identify whether key theoretical constructs in an intervention’s theory of
Autoimmune thyroid disease (AITD) is associated with other autoimmune endocrine diseases such as type 1 diabetes (T1D) and celiac disease (CeD). Thyroid peroxidase autoantibodies (TPOA) are biomarkers of AITD but may also occur in patients with other autoimmune diseases. We examined cross-sectional correlations between TPOA and an array of immune markers in a cohort of 90 children with exclusively
The Sun’s energy is effectively limitless. While resources such as coal or gas are finite, if you are able to capture and use solar power it doesn’t prevent anyone else from also using as much sunshine as they need.Except that isn’t quite the full story. Beyond a certain size, solar farms become large enough to affect the weather around them and ultimately the climate as a whole. In our new resear
Objectives: A measurement tool to assess systematic reviews 2 (AMSTAR 2) was originally developed for systematic reviews (SRs) of health-care interventions. The aim of this study was to assess the applicability of AMSTAR 2 to SRs of non-intervention studies. Study design and setting: This was a meta-research study. We used 20 SRs for each of the following four types of SRs: Diagnostic Test Accurac
This article reports measurements of the angle between differently defined jet axes in pp collisions at s = 5.02 TeV carried out by the ALICE Collaboration. Charged particles at midrapidity are clustered into jets with resolution parameters R = 0.2 and 0.4. The jet axis, before and after Soft Drop grooming, is compared to the jet axis from the Winner-Takes-All (WTA) recombination scheme. The angle
This is the software artifact for the paper "Efficient Demand Evaluation of Fixed-Point Attributes Using Static Analysis" published in SLE 2024.This artifact supports the evaluation of a new demand-driven algorithm for efficient circular Reference Attribute Grammar evaluation, specifically designed to improve performance of higly circular applications, e.g., dataflow analyses for Java. The artifac
Complex metabolic diseases due to overnutrition such as obesity, type 2 diabetes, and fatty liver disease are a major burden on the healthcare system worldwide. Current research primarily focuses on disease endpoints and trying to understand underlying mechanisms at relatively late stages of the diseases, when irreversible damage is already done. However, complex interactions between physiological
”All min strävan under denna skoldag – som ett jordeliv utgör – har varit att så mycket som möjligt främja det mänskliga broderskapets förverkligande på vår lilla jord.”Med dessa ord sammanfattade Nelly Thüring (1875–1972) sin livsfilosofi när hon vid 94 års ålder blev intervjuad av Socialdemokratiska kvinnoförbundets tidskrift Morgonbris. Som resetalare hade hon varit med och byggt upp det nystar”All I have strived for during this school day – that an earthly life amounts to – has been to do my utmost to promote the realization of human brotherhood on our little Earth.”This is how Nelly Thüring (1875–1972), at the age of 94, summarized her philosophy of life in an interview with Morgonbris, a journal published by the Swedish Social Democratic Women’s Federation. During the 1920s, she had
Nitrogen and sulfur are key elements in the biogeochemical cycles of marine ecosystems to which benthic foraminifera contribute significantly. Yet, cell-specific assimilation of ammonium, nitrate and sulfate by these protists is poorly characterized and understood across their wide range of species-specific trophic strategies. For example, detailed knowledge about ammonium and sulfate assimilation
