Investigation on the elimination of geyser in a cryogenic pipe by a recirculation method

A geyser elimination approach using recirculation methods is investigated in the present work, which is essential to guarantee the integrity of facilities. Both experimental and numerical methods are adopted in the investigation using LN2 as working fluids. A recirculation pipe is designed to eliminate geysers in a cryogenic vertical pipe. The performance of the recirculation method is comprehensi

Combining crystallography with quantum mechanics

In standard crystallographic refinement of biomacromolecules, the crystallographic raw data are supplemented by empirical restraints that ensure that the structure makes chemical sense. These restraints are typically accurate for amino acids and nucleic acids, but less so for cofactors, substrates, inhibitors, ligands and metal sites. In quantum refinement, this potential is replaced by more accur

Policy challenges to community energy in the EU : A systematic review of the scientific literature

In response to the ongoing climate crisis, many countries have issued policies to support the uptake of renewable energy. In the same vein, the European Union (EU) has issued a revised renewable energy directive in 2018. One of the pillars of the directive is the support for community energy initiatives, i.e. sustainable energy initiatives run by or with the participation of citizens. The concept

Shear-induced nanostructural changes in micelles formed by sugar-based surfactants with varied anomeric configuration

Hypothesis: The self-assembly of long tail sugar-based surfactants into worm-like micelles has recently been demonstrated, and the rheological properties of such systems have been shown to be tuneable through subtle modifications of the molecular characteristics of the surfactant monomer. In particular, the anomeric configuration of the hexadecylmaltoside headgroup was shown to induce profound cha

miR-126 contributes to the epigenetic signature of diabetic vascular smooth muscle and enhances antirestenosis effects of Kv1.3 blockers

Objectives: Restenosis after vessel angioplasty due to dedifferentiation of the vascular smooth muscle cells (VSMCs) limits the success of surgical treatment of vascular occlusions. Type 2 diabetes (T2DM) has a major impact on restenosis, with patients exhibiting more aggressive forms of vascular disease and poorer outcomes after surgery. Kv1.3 channels are critical players in VSMC proliferation.

Target Localization and Circumnavigation with Integral Action in R2

Prior results on target localization and circumnavigation with bearing measurements in $\mathbb {R}^{2}$ are extended with integral action, resulting in a control system that is robust to bounded load disturbances on the control inputs. Such disturbances may arise in practice due to modeling errors and need to be considered to ensure small tracking errors. The control inputs are modeled as the sys

Brottslingar av en mycket speciell sort. : Spionskandalen som en maktkamp mellan visselblåsare, grävande journalister och underrättelsetjänster.

Spy scandals in Western democracies can be seen as a power battle between three actors: investigative journalists, whistleblowers and the intelligence organizations at the center of the scandal. It is a conflict played out both within and outside of the court-house as the actors try to claim the label “hero” for themselves while actively trying to repudiate other labels, such as “traitor”, “spy” o

Acceptability of a digital return-to-work intervention for common mental disorders : a qualitative study on service user perspectives

Background: There is an evident discrepancy between need and provision of evidence-based return-to-work (RTW) interventions in existing mental health services. Online dissemination of evidence-based interventions is presumed to reduce this gap. However, there is almost no knowledge available on perceived acceptability of digital RTW interventions among service users, which are factors that might i

A review of HVAC solution-sets and energy performace of nearly zero-energy multi-story apartment buildings in Nordic climates by statistical analysis of environmental performance certificates and literature review

Multi-story apartment buildings, also known as multi-family or multi-unit residential buildings, represent the largest share of newly constructed, residential floor area in Norway, Sweden and Finland. Since the start of 2021, these buildings are required to be nearly-zero-energy under the Energy Performance of Buildings Directive. However, there has been limited research into defining solution-set

Yippee like 4 (Ypel4) is essential for normal mouse red blood cell membrane integrity

The YPEL family genes are highly conserved across a diverse range of eukaryotic organisms and thus potentially involved in essential cellular processes. Ypel4, one of five YPEL family gene orthologs in mouse and human, is highly and specifically expressed in late terminal erythroid differentiation (TED). In this study, we investigated the role of Ypel4 in murine erythropoiesis, providing for the f

Complement inhibitor CSMD1 modulates epidermal growth factor receptor oncogenic signaling and sensitizes breast cancer cells to chemotherapy

Background: Human CUB and Sushi multiple domains 1 (CSMD1) is a large membrane-bound tumor suppressor in breast cancer. The current study aimed to elucidate the molecular mechanism underlying the effect of CSMD1 in highly invasive triple negative breast cancer (TNBC). Methods: We examined the antitumor action of CSMD1 in three TNBC cell lines overexpressing CSMD1, MDA-MB-231, BT-20 and MDA-MB-486,

Bone remodeling and implant migration of uncemented femoral and cemented asymmetrical tibial components in total knee arthroplasty - DXA and RSA evaluation with 2-year follow up

Background: Aseptic loosening is one of the major reasons for late revision in total knee arthroplasty (TKA). The risk of aseptic loosening can be detected using radiostereometric analysis (RSA), whereby micromovements (migration) can be measured, and thus RSA is recommended in the phased introduction of orthopedic implants. Decrease in bone mineral density (BMD), as measured by dual-energy x ray

Novel insights into peptide amidation and amidating activity in the human circulation

C-terminal α-amidation is the final and essential step in the biosynthesis of several peptide hormones. Peptidylglycine α-amidating monooxygenase (PAM) is the only known enzyme to catalyse this reaction. PAM amidating activity (AMA) is known to be present in human circulation, but its physiological role and significance as a clinical biomarker remains unclear. We developed a PAM-specific amidation

Sarcopenia and dosimetric parameters in relation to treatment-related leukopenia and survival in anal cancer

Background: Treatment-related white blood cell (WBC) toxicity has been associated with an inferior prognosis in different malignancies, including anal cancer. The aim of the present study was to investigate predictors of WBC grade ≥ 3 (G3+) toxicity during chemoradiotherapy (CRT) of anal cancer. Methods: Consecutive patients with locally advanced (T2 ≥ 4 cm—T4 or N+) anal cancer scheduled for two

Facilitators for and barriers to radiography research in public healthcare in Nordic countries

Introduction:It has been suggested that the future of diagnostic imaging relies on engagement inresearch and evidence-based practice. This implies a role transition from a clinical radiographer to aclinical radiographer-researcher. Clinical radiographers’stimuli for engaging in research in Nordiccountries are unknown. This study aimed to address this gap.Methods:Cross-sectional data collection via

Opportunities to reduce pollination deficits and address production shortfalls in an important insect pollinated crop

Pollinators face multiple pressures and there is evidence of populations in decline. As demand for insect-pollinated crops increases, crop production is threatened by shortfalls in pollination services. Understanding the extent of current yield deficits due to pollination and identifying opportunities to protect or improve crop yield and quality through pollination management is therefore of inter

Media and mood work : Routines, daydreams and micro-moves

The intensive discussions of the digitalization of everyday life in the decades around 2000 often focused on how media invaded the home, reorganizing many mundane activities and sociabilities, creating new dependencies and skills of multitasking, as well as dangers of mental overload. Easily forgotten was how the new digital life was based upon a platform of domesticated media use created earlier.
