Improved global-local model to predict guided-wave scattering patterns from discontinuities in complex parts

2019

Ultrasonic guided-wave testing can greatly benefit from (1) an ability to provide quantitative information on the damage that is being detected, and (2) an ability to select the best mode-frequency combination for maximum sensitivity to a given type of damage. Achieving these capabilities in complex structures (e.g. nonprismatic structures such as a stiffened panel in aerospace fuselages) is a nontrivial task. This paper will discuss an improved Global-Local (GL) method where the geometrical “local” discontinuity (e.g. the stiffener) is modelled by traditional FE discretization and the rest of the structure (“global” part) is modelled by Semi-Analytical Finite Element (SAFE) cross-sectional…

Global–local model for three-dimensional guided wave scattering with application to rail flaw detection

2021

This study presents a three-dimensional global–local formulation for the prediction of guided wave scattering from discontinuities (e.g. defects). The approach chosen utilizes the Semi-Analytical Finite Element method for the “global” portion of the waveguide, and a full Finite Element discretization for the “local” portion of the waveguide containing the discontinuity. The application of interest is the study of guided wave scattering from transverse head defects in rails. Theoretical scattering results are impossible to obtain in this case for a wide-frequency range. While three-dimensional Semi-Analytical Finite Element–Finite Element models for guided wave scattering studies have been …

Reflections on the 25th Congress of the European Society for Pediatric Urology Part 1

2014

The 25th annual meeting of the European Society for Pediatric Urology (ESPU) took place in Innsbruck, Austria from the 7th to 10th of May 2014. The Specialty Chief Editor and nine Associate editors of Frontiers in Pediatrics, Pediatric Urology were in attendance. Each was asked to select the two presentations that they considered most significant. Here, we highlight some of the papers that we found of particular interest and that may impact our practices. This report reflects personal preferences of the authors and does not pretend to be comprehensive or to rank the quality of the presentations. We are aware that some important presentations may not be included. Our selections are presented…

Prevalence of Levator Ani Defects in Urogynecological Patients

2016

Introduction: Defects of the levator ani muscle complex could represent a pathophysiological link between vaginal birth trauma and urogynecological symptoms many years later. The aim of our study was to determine the prevalence of levator ani muscle defects using 3D or 4D ultrasound and palpation in urogynecological patients. Material and Methods: Urogynecological patients were retrospectively investigated using 3D or 4D ultrasound. Clinical examination consisted of palpation and 3D or 4D imaging of the levator ani muscle. Results: A total of 319 women were included in the analysis. Mean age was 64.9 years, average parity was 2.1. Stress incontinence was present in 50.8 %, overactive bladde…

Prevalence of silent fecal and urinary incontinence in women from the town of Teruel

2005

OBJECTIVES To study the prevalence of fecal (FI) and urinary incontinence (UI) in women from Teruel (Spain), as well as the clinical conditions associated with these disorders. METHODS We studied prospectively women with an age range of 20-64 years who were randomly selected from the population seen in a primary care center because of medical disorders not related to incontinence. Patients with functional or cognitive impairment were excluded. Medical and obstetric antecedents, as well as the type and frequency of incontinence symptoms were collected in a questionnaire. RESULTS Out of 115 women, 103 completed the study (mean age: 41+/-12 years range 20-64). UI was present in 34.9% (stress 3…

Qualit�tssicherung in der not�rztlichen Fortbildung

1996

Medizinische Leistungen unterliegen der Qualitatssicherung, die kontinuierliche Fortbildung ist ein wesentliches Instrument, dessen Qualitatselemente ebenfalls kontrolliert werden mussen: Struktur (Inhalte, Organisationsformen), Prozes (Ablauf) und Ergebnis (Akzeptanz, Vermehrung des Wissens). Es mus zwischen Fortbildungsbedarf (z.B. zertifizierter Nachweis) und -bedurfnis (Aufgabe des Arztes) differenziert werden, die Vielfalt der Fortbildungsformen spiegelt unterschiedliche Lernanforderungen wider. Anhand der neuen Richtlinien zum Fachkundenachweis „Rettungsdienst“ konnen qualitatssichernde Masnahmen dargestellt werden. Strukturqualitat: Die bisherigen Empfehlungen von 1983 wurden in den …

Defining female voiding dysfunction: ICI-RS 2011

2012

Whilst symptoms of bladder outlet obstruction (BOO) and post micturition symptoms are more commonly reported in men a significant number of women may also complain of voiding dysfunction. However, despite the recent advances in the standardisation of terminology of lower urinary tract dysfunction there remains a lack of consensus regarding a precise diagnosis and definition of voiding abnormalities in women. In addition voiding symptoms may co-exist with storage symptoms as well as those associated with urinary incontinence. Consequently many patients present with a spectrum of different urinary symptoms, related to both storage and voiding, which may be multifactorial in origin or be relat…

Quality of Life and Health in Patients with Urinary Diversion: A Comparison of Incontinent versus Continent Urinary Diversion

1997

Objective: To compare the quality of life and health in patients with incontinent and continent urinary diversions, in correlation with the initial diagnosis, diversion-related symptoms, psychological status and employment status. Materials and Methods: 81 patients (64% male and 36% female) with a mean age of 55 years (18-65 years) were included in this retrospective study. A total of 27 had an incontinent urinary diversion (group A) and 54 a continent diversion (group B). The initial diagnosis was malignant tumor in 75% (n = 61) and nontumor disease in 25% (n = 20). A structured interview and psychometric instrument assessment of the quality of life as well as somatic and psychological sym…

Can we prevent incontinence?: ICI-RS 2011

2012

Aims A review of the current state of research with regard to prevention of incontinence. Methods The search was limited to English language publications on the topic of incontinence prevention. Results Incontinence is associated with a range of risk factors, most of which are modifiable. Lifestyle changes with behavioral modifications that can prevent urinary incontinence (UI) need to be adopted from an early phase of life. Pregnancy per se for the woman, independent of labor and delivery practice, is a risk factor for UI. The influence of estrogen is still under discussion as to its direct influence to UI. For both men and women, there is a correlation between pelvic-floor related surgery…
