Investigating effects in GNSS station coordinate time series

2014

The vertical and horizontal displacements of the Earth can be measured to a high degree of precision using GNSS. Time series of Latvian GNSS station positions of both the EUPOS®-Riga and LatPos networks have been developed at the Institute of Geodesy and Geoinformation of the University of Latvia (LU GGI). In this study the main focus is made on the noise analysis of the obtained time series and site displacement identification. The results of time series have been analysed and distinctive behaviour of EUPOS®-Riga and LatPos station coordinate changes have been identified. The possible dependences of GNSS station coordinate distribution on EPN station problems, seismic activity of some area…

Perceived stress in relation to quality of life and resilience in patients with advanced chronic kidney disease undergoing hemodialysis

2021

Background: Patients with chronic kidney disease undergo various stages of therapeutic adaptation which involve lifestyle modifications, physical changes, and adjustment to renal replacement therapy. This process produces adaptive stress. Objective: To identify how resilience, health- related quality of life, and sociodemographic, clinical, and hemodialysis routine-related variables are related to perceived stress in patients with chronic kidney disease receiving hemodialysis for more than six months. Methods: This was a multicenter and cross-sectional study involving 144 patients from the Valencian Community (Spain). The assessment scales used for the study were the Perceived Stress Scale …

Multidisciplinary management of Hunter syndrome.

2009

Hunter syndrome is a rare, X-linked disorder caused by a deficiency of the lysosomal enzyme iduronate-2-sulfatase. In the absence of sufficient enzyme activity, glycosaminoglycans accumulate in the lysosomes of many tissues and organs and contribute to the multisystem, progressive pathologies seen in Hunter syndrome. The nervous, cardiovascular, respiratory, and musculoskeletal systems can be involved in individuals with Hunter syndrome. Although the management of some clinical problems associated with the disease may seem routine, the management is typically complex and requires the physician to be aware of the special issues surrounding the patient with Hunter syndrome, and a multidiscipl…

Psychosocial impact of malocclusion in Spanish adolescents

2013

Objective: To evaluate the psychosocial impact of malocclusion, determine its relationship with the severity of malocclusion, and assess the influence of gender and social class on this relationship in adolescents. Methods: A random sample of 627 Spanish adolescents aged 12 - 15 years underwent intraoral examinations by 3 calibrated examiners (intraexaminer and interexaminer kappa > 0.85) at their schools. Psychosocial impact was measured through a self-rated Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ). The severity of malocclusion was measured by the Index of Orthodontic Treatment Need (IOTN). Gender and social class were also recorded. Results: The total PIDAQ score and…

Effect of pressure and temperature on viscosity of a borosilicate glass

2018

International audience; During industrial glass production processes, the actual distribution of stress components in the glass during scribing remains, to date, poorly quantified, and thus continues to be challenging to model numerically. In this work, we experimentally quantified the effect of pressure and temperature on the viscosity of SCHOTT N-BK7 glass, by performing in situ deformation experiments at temperatures between 550 and 595 °C and confining pressures between 100 MPa and 300 MPa. Experiments were performed at constant displacement rates to produce almost constant strain rates between 9.70 × 10 −6 s-1 and 4.98 × 10-5 s-1. The resulting net axial stresses range from 81 MPa to 8…

High-urgency kidney transplantation in the Eurotransplant Kidney Allocation System : success or waste of organs? The Eurotransplant 15-year all-centr…

2016

Item does not contain fulltext BACKGROUND: In the Eurotransplant Kidney Allocation System (ETKAS), transplant candidates can be considered for high-urgency (HU) status in case of life-threatening inability to undergo renal replacement therapy. Data on the outcomes of HU transplantation are sparse and the benefit is controversial. METHODS: We systematically analysed data from 898 ET HU kidney transplant recipients from 61 transplant centres between 1996 and 2010 and investigated the 5-year patient and graft outcomes and differences between relevant subgroups. RESULTS: Kidney recipients with an HU status were younger (median 43 versus 55 years) and spent less time on the waiting list compared…

Effect of epicentral direction on seismic response of asymmetric buildings

1984

The paper deals with the influence of the epicentral direction on the displacement and stress response of multistorey asymmetric buildings to earthquake horizontal ground motion. A method is given for computing for each plane frame of the complex structure a particular direction of the bidirectional stationary random input for which the horizontal floor displacement of the given frame is maximized. It is shown that this direction can be considered conservative for the corresponding non-stationary process.

Zusammenhang zwischen postoperativer Liegedauer der Redon-Drainage und Wundheilung

1997

Es wurde bei 150 Patienten mit totalendoprothetischem Huftgelenkersatz der Einflus der postoperativen Liegedauer von Redon-Drainagen auf die Wundheilung untersucht. Eine genaue Analyse der Liegedauer der Drainagen sowie deren bakterielle Keimbesiedelung sollte unter Berucksichtigung des Wundheilungsverlaufs Aufschlus uber etwaige Zusammenhange verschaffen. Auserdem sollte uberpruft werden, inwieweit die Drainagenbakteriologie eine geeignete Methode ist, eine Aussage uber die Wundsituation zu treffen. 150 Patienten wurden in drei Kollektive eingeteilt. Zwei davon (je 50 Patienten) wurden im selben Zeitraum operiert, wobei die Patienten der einen Gruppe wegen einer Wundheilungsstorung bzw. ei…

Reconsidérer les mobilités quotidiennes en prenant en compte les habitudes individuelles

2019

Depuis quelques années, on constate dans la littérature un regain d’intérêt pour une analyse des habitudes lorsqu’elles concernent les mobilités quotidiennes (Brette et al., 2014 ; Schwanen et al., 2012). Par « habitude » il faut comprendre non pas la simple répétition de trajets, mais bel et bien un ensemble de savoir-faire acquis par l’expérience ou par l’éducation (Kaufmann, 2001). Par exemple, une personne ayant une forte habitude automobile, a tendance à automatiser (d’un point de vue cognitif) de plus en plus ses trajets quotidiens, à s’en détacher, pour associer à ses déplacements des activités plus ou moins « productives » (ex : envoyer des mails, des messages, téléphoner, regarder …

2020

This study aimed to explore the acute effects of static stretching on the musculotendinous properties of two hamstring muscles. Twelve male volunteers underwent two testing sessions. One session was dedicated to the evaluation of the semitendinosus muscle before (PRE) and after (POST) static stretching (five sets of 30-s stretching), and the other session similarly explored the long head of biceps femoris muscle. In addition to the displacement of the myotendinous junction (MTJ), passive torque and maximal voluntary isometric torque (MVIT) were evaluated. MVIT (−8.3 ± 10.2%, p = 0.0036, d = 0.497) and passive torque (−28.4 ± 16.9%, p = 0.0003, d = 1.017) were significantly decreased POST st…
