The operation of a froth flotation column can be described by a nonlinear convection–diffusion partial differential equation that incorporates the solids–flux and drift–flux theories as well as a model of foam drainage. The resulting model predicts the bubble and (gangue) particle volume fractions as functions of height and time. The steady-state (time-independent) version of the model defines so-

OBJECTIVE: To report population-based clinical presentation and outcomes in patients with urosymphyseal fistula (USF) after pelvic radiotherapy (RT). PATIENTS AND METHODS: A retrospective chart review was performed in 33 consecutive patients diagnosed with suspicion of USF in a tertial referral center from 2014-2022 to ascertain information about diagnostic delay, clinical presentation, precipitat

Cette étude est ancrée dans une approche transdisciplinaire de l’apprentissage des langues secondes et étrangères (Douglas Fir Group 2016), composée de trois niveaux interdépendants : un niveau macro, caractérisé par des structures idéologiques et politiques à l’échelle de la société, un niveau méso où se situent les établissements scolaires régis par des contraintes sociales, économiques et cultu

Background and Objectives Small vessel disease (SVD) and neuroinflammation both occur in Alzheimer disease (AD) and other neurodegenerative diseases. It is unclear whether these processes are related or independent mechanisms in AD, especially in the early stages of disease. We therefore investigated the association between white matter lesions (WML; the most common manifestation of SVD) and CSF b

Background Epidemiological studies have shown that impaired lung function is common and associated with increased risk of cardiovascular disease. Increased levels of several inflammatory and cardiovascular disease-related plasma proteins have been associated with impaired lung function. The aim was to study the association between plasma proteomics and forced expiratory volume in 1 s (FEV1), force

Reconstruction of attosecond beating by interference of two-photon transitions (RABBITT) is a powerful photoelectron spectroscopy, offering direct access to internal dynamics of the target. It is being increasingly applied to molecular systems, but a general, computationally tractable theory of RABBITT spectra in molecules has so far been lacking. We show that under quite general assumptions, RABB

Previous reports of mortality and morbidity in pediatric severe traumatic brain injury (TBI) vary considerably, with few population-based studies. Mortality rates from 3-33 % and varying morbidity have been reported, most commonly using the Extended Glasgow Outcome Scale (eGOS). The Lund concept is a treatment algorithm for severe TBI aiming at controlling intracranial pressure (ICP) by reducing c

Importance: We know little about the transmission of obsessive-compulsive disorder (OCD) across generations. Objective: To evaluate the sources of parent-offspring transmission of OCD and familial cross-generational association with more typical anxiety disorders. Design, Setting, and Participants: This Swedish population register-based study analyzed data for offspring born in Sweden from 1960 to

Pebble accretion is recognized as a significant accelerator of planet formation. Yet only formulae for single-sized (monodisperse) distribution have been derived in the literature. These can lead to significant underestimates for Bondi accretion, for which the best accreted pebble size may not be the one that dominates the mass distribution. We derive in this paper the polydisperse theory of pebbl

Historiska aktörer är långt ifrån frånvarande i historieforskningen. Varje land och varje tidsepok har sin beskärda del av biografier över framstående vetenskapsmän, intellektuella och utbildningsreformatorer. Trots detta är det inte fel att hävda att de teoretiska strömningar som har satt sin prägel på historiska och sociologiska studier av kunskap sedan 1960-talet har betonat strukturer framför Historical actors are central to the history of knowledge as they are to all historical scholarship. Every country, every era has its biographies of eminent scientists, intellectuals, and educational reformers. Yet the theoretical currents that have left their mark on the historical and sociological study of knowledge since the 1960s have emphasized structures over actors, collectives over individ

Aims: To develop a suite of quality indicators (QIs) for the evaluation of the care and outcomes for adults with pulmonary arterial hypertension (PAH). Methods and results: We followed the European Society of Cardiology (ESC) methodology for the development of QIs. This included (i) the identification of key domains of care for the management of PAH, (ii) the proposal of candidate QIs following sy
