We perform phantom and numerical studies of the changes in molecular oxygen and water vapor spectroscopic signals, showing the potential of measuring pulmonary volume changes with GASMAS technique in neonates.
The gas flow field design plays a vital role in the cell performance of proton exchange membrane fuel cells, especially at high current densities. In this study, wavy flow channels are designed and adopted on the cathode side to enhance the mass transport process. Results demonstrate that the wavy flow channels proposed in this paper significantly improve cell performance at high current densities
Animals vary widely in body size within and across species. This has consequences for the function of organs and body parts in both large and small individuals. How these scale, in relation to body size, reveals evolutionary investment strategies, often resulting in trade-offs between functions. Eyes exemplify these trade-offs, as they are limited by their absolute size in two key performance feat
Background: Post-covid syndrome is an emerging condition involving a wide range of symptoms, including high rates of poor mental health. The diagnostic relevance and clinical severity of these symptoms are largely unknown, and evidence for treatment of post-covid mental health symptoms is lacking. This protocol describes a pilot randomized clinical trial, primarily aiming to assess feasibility, pa
Thyroid function has a widespread effect on the cardiometabolic system. However, the causal association between either subclinical hyper-or hypothyroidism and the thyroid hormones with blood pressure (BP) and cardiovascular diseases (CVD) is not clear. We aim to investigate this in a two-sample Mendelian randomization (MR) study. Single nucleotide polymorphisms (SNPs) associated with thyroid-stimu
Isolation of long-term hematopoietic stem cell (HSC) is possible by utilizing flow cytometry with multiple cell surface markers. However, those cell surface phenotypes do not represent functional HSCs after in vitro culture. Here we show that cultured HSCs express mast cell-related genes including Cd244. After in vitro culture, phenotypic HSCs were divided into CD244- and CD244+ subpopulations, an
Background: Repetitive head injury in contact sports is associated with cognitive, neurobehavioral, and motor impairments and linked to a unique neurodegenerative disorder: chronic traumatic encephalopathy (CTE). As the clinical presentation is variable, risk factors are heterogeneous, and diagnostic biomarkers are not yet established, the diagnostic process of CTE remains a challenge. The general
Background: This study will explore implementation mechanisms through which a single implementation strategy and a multifaceted implementation strategy operate to affect the implementation outcome, which is fidelity to the Guideline For The Prevention of Mental Ill Health within schools. The guideline gives recommendations on how workplaces can prevent mental ill health among their personnel by ma
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of non-opioid analgesics in neonates (term or preterm) exposed to procedural pain compared to placebo or no drug, non-pharmacological intervention, other analgesics, or different routes of administration.
INTRODUCTION: Collagenous colitis (CC) is a common cause of chronic diarrhea and is characterized by a subepithelial thickened collagen layer in the colonic mucosa. It shares many of the characteristics found in autoimmune diseases, but no autoantibodies have been identified. In CC, an imbalance in collagen turnover is evident. The purpose of the present study was to investigate whether any collag
During March 2020 a large-span arena, Tarfalahallen, collapsed. The main load-bearing girders with a 54 m span were high and slender glulam trussed beams, supported from below by a cable system via vertical struts. Investigations concluded that the failure was initiated by out-of-plane buckling of the struts and slender beam, in spite of lateral stabilization by steel roof sheeting at the top edge
Vad ska en surrogatmamma känna inför fostret hon bär i sin mage? Hur ska en hårt arbetande förälder förhålla sig till faktumet att nannyn eller kalasfixaren vet bäst hur deras barn vill ha sitt kalas? Kan en flygvärdinna eller en socialarbetare visa den irritation hon känner inför en otrevlig kund eller klient? Vilka känslor är legitima att visa upp i olika situationer och vilka behöver tryckas ne
After a 7-year slowdown in economic growth in the previous decade, LAC opened this decade with the adverse effects of Covid. The economic slowdown and the health crisis jeopardized the SDGs’ implementation in the region. In this chapter, the authors revisit the old question of whether the previous decade of LAC is another lost decade, mainly adding the environmental dimension to the economic and s
This article reflects on Max Weber’s idea of disenchantment in relation to the material turn within contemporary religious studies. In the first part, I return to the two most famous texts in which Weber uses the concept, with particular attention to the historical context in which these texts were penned. In the following part, I discuss some of the contemporary efforts to engage critically with
Purpose/Background: Appendectomy is the standard treatment of acute appendicitis (AA) but conservative treatment has gained success. The need for follow-up after conservatively treated AA is unclear. Hypothesis/Aim: This study evaluates follow-up, recurrence and appendiceal malignancy in conservatively treated AA. Methods/Interventions: This retrospective study included patients with conservativel
STUDY QUESTION: Does previous bariatric surgery (BS) in women affect cumulative live birth rate in IVF?SUMMARY ANSWER: Women having had BS seem to have the same cumulative live birth rate as non-operated women of the same BMI at IVF treatment.WHAT IS KNOWN ALREADY: Because of the perinatal risks of obesity to mother and infant as well as impaired outcomes of IVF, obese women are advised to reduce
STUDY QUESTION: Is the chance of childbirth, and risk of infertility, pregnancy loss and need for assisted reproduction different for women with asthma compared to women without asthma?SUMMARY ANSWER: Women with asthma had comparable chances of giving birth compared to the reference population, however, their risk of both infertility and pregnancy loss, as well their need for medically assisted re

In modern society, the consumption of fossil fuels has been increasing drastically, leading to significant emissions of carbondioxide (CO2), air pollution, global warming, and political and economic imbalances. This has increased the interest inrenewable and sustainable energy sources such as wind- and hydropower, solar energy, and in energy conversion by fuel celltechnology, and water electrolyse
Previous research on A/B testing and continuous experimentation has mostly focused on large-scale settings with company-external customers. However, work efficiency and satisfaction for company coworkers may be highly related to internal tools and their fit-for-use. In this study, we therefore explore A/B testing for online services exclusively used by company co-workers. We A/B tested two version
