Natural micro-scale heterogeneity induced solute and nanoparticle retardation in fractured crystalline rock.

2011

Abstract We studied tracer (Tritiated Water (HTO); Tritium replaces one of the stable hydrogen atoms in the H 2 O molecule) and nanoparticle (quantum dots (QD)) transport by means of column migration experiments and comparison to 3D CFD modeling. Concerning the modeling approach, a natural single fracture was scanned using micro computed tomography (μCT) serving as direct input for the model generation. The 3D simulation does not incorporate any chemical processes besides the molecular diffusion coefficient solely reflecting the impact of fracture heterogeneity on mass (solute and nanoparticles) transport. Complex fluid velocity distributions (flow channeling and flowpath heterogeneity) evo…

Análisis cinético y cinemático de las articulaciones del mediopié durante la marcha en sujetos sanos: consideraciones clínicas

2016

Introducción: No existe todavía suficiente evidencia en estudios clínicos respecto al comportamiento del mediopié en situaciones dinámicas como la marcha o la carrera. El presente estudio pretende analizar el comportamiento mecánico de las articulaciones del mediopié mediante un modelo multisegmental del pie, con especial atención a los momentos articulares y sus repercusiones clínicas. Sujetos y métodos: Se realizó un estudio computarizado de la marcha sobre 30 sujetos adultos sanos (27,13 ± 3,82 a˜nos) con un índice de postura del pie (FPI) neutro (entre 0 y +5). Se estimaron los ángulos y momentos articulares externos en 3 dimensiones mediante un modelo que considera 3 segmentos (antepié…

Strange vegetation: Emotional undercurrents of Tove Jansson’s Moominvalley in November

2018

This article investigates the emotional undercurrents of Tove Jansson’s Moominvalley in November. I argue that one of the main characters of Jansson’s book is the autumn forest that surrounds the abandoned Moomin house. The decomposing forest is not just an emblem of the inner lives of the guests that gather in the house but is an active character itself: an ambiguous life form that creeps in the house and must be expelled from its living core. I further demonstrate that the emotion of disgust has a crucial role in Jansson’s narrative, and that an adequate analysis of the intentional content of disgust allows us to see what is at issue in the relations between the characters. In my reading,…

Impact of carbon ion irradiation on epidermal growth factor receptor signaling and glioma cell migration in comparison to conventional photon irradia…

2013

PURPOSE: Radiotherapy of malignant gliomas may be limited by an interference of radiation with the migratory potential of tumor cells. Therefore, the influence of conventional photon and modern carbon ion ((12)C) irradiation on glioblastoma cell migration and on epidermal growth factor receptor-related (EGFR) signaling was investigated in vitro. MATERIALS AND METHods: EGFR overexpressing glioblastoma cell lines U87 EGFR++ and LN229 EGFR++ were irradiated with 0, 2 or 6 Gy photons or (12)C heavy ions. Migration was analyzed 24 h after treatment in a standardized Boyden Chamber assay. At different time points EGFR, protein kinase B (PKB/AKT) and extracellular signal-related kinases (ERK1/2) w…

Functional correlate and delineated connectivity pattern of human motion aftereffect responses substantiate a subjacent visual-vestibular interaction.

2018

The visual motion aftereffect (MAE) is the most prominent aftereffect in the visual system. Regarding its function, psychophysical studies suggest its function to be a form of sensory error correction, possibly also triggered by incongruent visual-vestibular stimulation. Several observational imaging experiments have deducted an essential role for region MT+ in the perception of a visual MAE but not provided conclusive evidence. Potential confounders with the MAE such as ocular motor performance, attention, and vection sensations have also never been controlled for. Aim of this neuroimaging study was to delineate the neural correlates of MAE and its subjacent functional connectivity pattern…

A 3-D marker-free system for the analysis of movement disabilities--an application to the legs.

2001

The aim of this paper is to describe an approach allowing the analysis of human motion in three-dimensional (3-D) space. The system that we developed is composed of three charge-coupled-device cameras that capture synchronized image sequences of a human body in motion without the use of markers. Characteristic points belonging to the boundaries of the body in motion are first extracted from the initial images. Two-dimensional superquadrics are then adjusted on these points by a fuzzy clustering process. After that, the position of a 3-D model based on a set of articulated superquadrics, each of them describing a part of the human body, is reconstructed. An optical flow process allows the pr…

Reliability and concurrent validity of the Velowin optoelectronic system to measure movement velocity during the free-weight back squat

2018

The objective of this study was to explore the reliability and concurrent validity of the Velowin optoelectronic system to measure movement velocity during the free-weight back squat exercise. Thirty-one men (age = 27.5 ± 3.2 years; body height = 1.76 ± 0.15 m; body mass: 78.3 ± 7.6 kg) were evaluated in a single session against five different loads (20, 40, 50, 60 and 70 kg) and three velocity variables (mean velocity, mean propulsive velocity and maximum velocity) were recorded simultaneously by a linear velocity transducer (T-Force; gold-standard) and a camera-based optoelectronic system (Velowin). The main findings revealed that (1) the three velocity variables were determined with a h…

Liikuntaa opettavien opettajien ja kouluterveydenhoitajien yhteistyö oppilaiden toimintakyvyn edistämisessä ja Move!-järjestelmän hyödyntämisessä

2022

Tämän tutkimuksen tarkoituksena on tutkia liikuntaa opettavien opettajien ja kouluterveydenhoitajien käsityksiä moniammatillisesta yhteistyöstä toimintakyvyn edistämiseen ja Move!-mittauksiin liittyen. Kummatkin toimijat ovat keskeisiä oppilaiden toimintakyvyn edistämisessä sekä perusopetuksen opetussuunnitelmaan sisältyvän Move!-järjestelmän hyödyntämisessä. Tutkimus toteutettiin kyselytutkimuksena erikseen kouluterveydenhoitajille (N=192) ja liikuntaa opettaville opettajille (N=359). Määrällisten kysymysten analysoinnissa hyödynnettiin t-testiä sekä yksisuuntaista varianssianalyysiä ja laadullisen aineiston analyysissä teoriaohjaavaa sisällönanalyysiä. Tulosten mukaan korkeintaan noin puo…
