Quantitative imaging of KOH vapor in combustion environments using 266 nm laser-induced photofragmentation fluorescence

In biomass thermal conversion processes, the release of potassium in high temperature environments crucially influences the operating efficiency and safety. The dominant potassium species can be potassium hydroxide (KOH) and/or potassium chloride (KCl). We report a species-specified quantitative measurement of potassium hydroxide (KOH) in combustion environments using laser-induced photofragmentat

Pattern recognition receptor expression and maturation profile of dendritic cell subtypes in human tonsils and lymph nodes

Dendritic cells (DCs) with capacity of antigen cross-presentation are of key interest for immunotherapy against cancer as they can induce antigen-specific cytotoxic T lymphocyte (CTL) responses. This study describes frequencies of DC subtypes in human tonsils and lymph nodes, and phenotypic aspects that may be targeted by adjuvant measures. From human tonsils and neck lymph nodes, DCs were identif

Exit, voice and consensus – A legal and political analysis of the emergency brake in EU criminal policy

This post presents a political and legal analysis of the emergency brake in criminal law in Articles 82(3) and 83(3) TFEU. It suggests that the emergency brake offers a powerful discretionary prerogative for Member States seeking to protect the integrity of their criminal justice systems. This strong legal shield for Member States in the form of a ‘quasi-veto’ is contrasted with a tendency to deci

The Influence of Orbital Forcing on 10Be Deposition in Greenland Over the Glacial Period

Understanding the transport and deposition of the cosmogenic isotope 10Be is vital for the application of the isotope data to infer past changes of solar activity, to reconstruct past Earth’s magnetic field intensity and climate change. Here, we use data of the cosmogenic isotope 10Be from the Greenland ice cores, namely the NEEM and GRIP ice cores, to identify factors controlling its distribution

Forum : Interlingual relations: Approaches, conflicts, and lessons in the translation of global politics

At stake in this forum are the politics of translation in the study of global politics. More specifically, the following interventions aim to consider the ways that scholars can recenter the utility of language toward more flexible conceptions of relationality. As each contribution reveals, translation is indispensable to individual theorizations of international politics; yet taken together, the

Pro-tumoral behavior of omental adipocyte-derived fibroblasts in tumor microenvironment at the metastatic site of ovarian cancer

Adipocyte-rich omentum offers “good soil” for disseminating ovarian cancer (OvCa), contributing to therapeutic difficulty. However, little is understood about the association between adipocytes and tumor growth at peritoneal dissemination site. Herein, we report the induction of adipocyte dedifferentiation by OvCa cells and pro-tumorigenic effects of resulted adipocyte-derived fibroblasts. We conf

Strong inhibition of peptide amyloid formation by a fatty acid

The aggregation of peptides into amyloid fibrils is associated with several diseases, including Alzheimer's and Parkinson's disease. Because hydrophobic interactions often play an important role in amyloid formation, the presence of various hydrophobic or amphiphilic molecules, such as lipids, may influence the aggregation process. We have studied the effect of a fatty acid, linoleic acid, on the

NOEMA observations of CO emission in Arp 142 and Arp 238

Previous studies have shown significant differences in the enhancement of the star formation rate (SFR) and star formation efficiency (SFE = SFR/Mmol) between spiral–spiral and spiral–elliptical mergers. In order to shed light on the physical mechanism of these differences, we present NOEMA observations of the molecular gas distribution and kinematics (linear resolutions of ∼2 kpc) in two represen

Relationship between scoliosis, windswept hips and contractures with pain and asymmetries in sitting and supine in 2450 children with cerebral palsy

Purpose: This cross-sectional study of 2450 children with cerebral palsy aimed to analyse the prevalence and association of scoliosis, windswept hips, hip and knee contractures. Methods: Logistic regression was used to estimate associations with pain, postural asymmetries, and ability to change position for children at Gross Motor Function Classification System (GMFCS) levels I–V, aged 0–18 years.

European Association of Urology Guidelines on Non–muscle-invasive Bladder Cancer (Ta, T1, and Carcinoma in Situ)

Context: The European Association of Urology (EAU) has released an updated version of the guidelines on non–muscle-invasive bladder cancer (NMIBC). Objective: To present the 2021 EAU guidelines on NMIBC. Evidence acquisition: A broad and comprehensive scoping exercise covering all areas of the NMIBC guidelines since the 2020 version was performed. Databases covered by the search included Medline,

Functional and Oncological Outcomes After Open Versus Robot-assisted Laparoscopic Radical Prostatectomy for Localised Prostate Cancer : 8-Year Follow-up

Background: Radical prostatectomy reduces mortality among patients with localised prostate cancer. Evidence on whether different surgical techniques can affect mortality rates is lacking. Objective: To evaluate functional and oncological outcomes 8 yr after robot-assisted laparoscopic prostatectomy (RALP) and open retropubic radical prostatectomy (RRP). Design, setting, and participants: We enroll

Milky Way spiral arms from open clusters in Gaia EDR3

Context. The physical processes driving the formation of Galactic spiral arms are still under debate. Studies using open clusters favour the description of the Milky Way spiral arms as long-lived structures following the classical density wave theory. Current studies comparing the Gaia DR2 field stars kinematic information of the solar neighbourhood to simulations, find a better agreement with sho

Material perception and action : The role of material properties in object handling

This dissertation is about visual perception of material properties and their role in preparation for object handling. Usually before an object is touched or picked-up we estimate its size and shape based on visual features to plan the grip size of our hand. After we have touched the object, the grip size is adjusted according to the provided haptic feedback and the object is handled safely. Simil

Precipitating Amine Absorption Systems for Carbon Capture

Carbon capture using amine-based absorption is an established technology for the separation of gaseous CO2. It is used in the upgrading of gaseous fuels, and it has also been suggested that it could play a crucial role in the mitigation of climate change through post-combustion carbon capture and sequestration (CCS), and by creating carbon sinks through bioenergy CCS. One drawback of the existing

Solving the subset sum problem with a nonideal biological computer

We consider the solution of the subset sum problem based on a parallel computer consisting of self-propelled biological agents moving in a nanostructured network that encodes the computing task in its geometry. We develop an approximate analytical method to analyze the effects of small errors in the nonideal junctions composing the computing network by using a Gaussian confidence interval approxim

Performance and characterization of the FinEstBeAMS beamline at the MAX IV Laboratory

FinEstBeAMS (Finnish-Estonian Beamline for Atmospheric and Materials Sciences) is a multidisciplinary beamline constructed at the 1.5 GeV storage ring of the MAX IV synchrotron facility in Lund, Sweden. The beamline covers an extremely wide photon energy range, 4.5-1300 eV, by utilizing a single elliptically polarizing undulator as a radiation source and a single grazing-incidence plane grating mo

Influence of potassium chloride on PAH concentration during soot formation studied using laser-induced fluorescence

Previous studies have shown that addition of potassium chloride (KCl) reduces soot concentration and primary particle size. To improve the understanding of this phenomenon, this work focuses on investigating the influence of KCl addition on formation of polycyclic aromatic hydrocarbons (PAHs), assumed to be precursors of soot. The method used is laser-induced fluorescence (LIF), for which differen
