Failure by corrosion in PC bridges: A case history of a viaduct in Italy
2016
Purpose The paper illustrates a viaduct collapse due to corrosion phenomena. Moreover, a contribution to the issues related to both the control of existing structures and design methods to be followed for the construction of new buildings is provided. Design/methodology/approach The objectives were achieved by in situ observations and numerical analyses. The effects of corrosion phenomena are investigated, and the progressive collapse analysis is provided to be helpful in this case. Findings The damages induced by corrosion phenomena have caused the collapse of the viaduct taken in to account. The performed numerical analyses were able to reproduce the effects of corrosion in terms of redu…
EUGENICS AND SOCIALIST THOUGHT IN THE PROGRESSIVE ERA: THE CASE OF JAMES MEDBERY MACKAYE
2018
The aim of this essay is to assess James Medbery MacKaye’s contribution to socialist thought during the Progressive Era. Largely forgotten today, MacKaye proposed a special version of socialism, which he called “Pantocracy,” based on a peculiar blend of utilitarian and eugenic assumptions. Specifically, MacKaye held that biological fitness mapped to the capacity for happiness—biologically superior individuals possess a greater capacity for happiness—and saw the eugenic breeding of “a being or race of beings capable in the first place of happiness” as a possibility open by the advent of Pantocracy. Incidentally, this essay provides further evidence that the influence of eugenic and racialist…
Using skeleton and Hough transform variant to correct skew in historical documents
2020
International audience; As a main part of several document analysis systems, Skew estimation represents one of the major research challenges, particularly in case of historical documents exploration. In this paper, we propose an original skew angle detection and correction technique. Morphological Skeleton is introduced to considerably diminish the amount of data by eliminating the redundant pixels and preserving only the central curves of the image components. Next, the proposed method uses Progressive Probabilistic Hough Transform (PPHT) to find image lines. At the end, a specific procedure is applied in order to measure the global skew angle of the document image from these identified li…
Chronic progressive external ophthalmoplegia with a novel mitochondrial DNA deletion and a mutation in the tRNALEU(UUR) gene
1999
Large-scale deletions and point mutations of the mitochondrial DNA are generally accepted as being involved in the pathogenesis of diseases associated with mitochondrial encephalomyopathies such as Kearns-Sayre syndrome and chronic progressive external ophthalmoplegia (CPEO). We screened suspected patients using polymerase chain reaction techniques, Southern blot analyses, and muscle biopsy specimens. We report on a novel 4,953-base pair deletion associated with a familial occurrence of a tRNA Leu(UUR) T3250C point mutation in a young female patient clinically diagnosed with CPEO. This deletion is not flanked by direct repeats, so slip replication and homologous recombination do not seem li…
LONG-TERM STRUCTURAL DEFICIENCIES IN A MAT FOUNDATION ON CLAY SOIL
2013
A 3-story building with a mat foundation consisting of a slab on a grid of grade beams performed poorly on clay soil. Cracking of the slab became rogressively worse as a result of the incorrect esign and fluctuations in the groundwater pressure under the foundation. The cyclic presence and absence of water rusted the steel reinforcement, and the sulfates in the clay soil caused formation of ettringite in the concrete. Plastic hinges formed in the slab and settlements occurred, causing damage to the beams. The situation is still in progress and may lead to the collapse of the structure under normal service conditions. The geotechnical and structural investigations performed to survey and ass…
Brotes de gastroenteritis aguda vírica en residencias de ancianos: Sistema de Detección por Umbral de Prevalencia (SiDUP)
2009
Javier Buesa Gómez (Javier.Buesa@uv.es) Se describen las intervenciones llevadas a cabo en una unidad de epidemiología local, durante varios años, relacionadas con la epidemiología de la gastroenteritis por norovirus en residencias de ancianos de Castellón. Desde varios brotes acaecidos en un mismo geriátrico, hasta el estudio de los casos esporádicos que determinan la situación endémica en varias residencias. Este trabajo se centra en el análisis de esa situación endémica de síntomas digestivos en periodos de silencio epidémico y la propuesta de un método sencillo para detectar el inicio de brotes de GEA de transmisión progresiva (persona-persona) que hemos denominado Sistema de Detección …
Das Cogan-I-Syndrom
2003
Wir berichten uber 2 Patienten, die seit dem Sauglings- und Kleinkindesalter unter einem Cogan-I-Syndrom leiden.Bei diesem seltenen Krankheitsbild handelt es sich um eine akute oder schubweise Verschlechterung der Horleistung des Innenohrs mit vestibularer Symptomatik und einer nichtsyphilitischen interstitiellen Keratitis oder anderen entzundlichen okularen Symptomen beim atypischen Cogan-I-Syndrom. Die erste Patientin erkrankte im 5.Lebensjahr an verschiedenen okularen Entzundungen, sodass ein Auge im 8.Lebensjahr erblindete.Zu dieser Zeit begann die Horverschlechterung. Im Alter von 17 Jahren litt die Patientin beidseits unter einer an Taubheit grenzenden Schwerhorigkeit. Bei dem zweiten…
Zur Frage der Gestagentherapie bei der progressiven Sklerodermie des Mannes
1970
Bei 6 mannlichen Kranken mit progressiver Sklerodermie wird anhand von Hodenbiopsien, Spermiogrammen und der Bestimmung der Initialfructose die Einwirkung der bei dieser Grunderkrankung durchgefuhrten Gestagenmedikation (Primolut-Nor®) auf Potentia generandi, Potentia coeundi und Libido untersucht.
Manometrische untersuchungen zur oesophagusbeteiligung bei progressiver sklerodermie
1975
Bei 15 Patienten mit progressiver Sklerodermie wurde die Oesophagus funktion manometrisch und radiologisch untersucht. Nur ein Drittel der Patienten gab Schluckbeschwerden an. Dagegen liesen sich radiologisch bei 8 Patienten (55%) deutliche Motilitatsstorungen nachweisen, mit der Oesophagusmanometrie sogar bei 11 Patienten (73%). Fehlende subjektive Symptome schliesen demnach einen ausgedehnten Befall der Speiserohre nicht aus. Die manometrischen Messungen zeigen, das mit einer Beteiligung der Speiserohre im odematos-indurativen Stadium der Sklerodermie in einem wesentlichen hoheren Prozentsatz gerechnet werden mus, als ublicherweise aufgrund von Rontgenuntersuchungen allein angenommen wurd…
Hematopoietic Stem Cell Transplantation in People With Active Secondary Progressive Multiple Sclerosis
2023
Background and ObjectivesUncontrolled evidence suggests that autologous hematopoietic stem cell transplantation (AHSCT) can be effective in people with active secondary progressive multiple sclerosis (SPMS). In this study, we compared the effect of AHSCT with that of other anti-inflammatory disease-modifying therapies (DMTs) on long-term disability worsening in active SPMS.MethodsWe collected data from the Italian Bone Marrow Transplantation Study Group and the Italian Multiple Sclerosis Register. Patients were considered eligible if treatment had been started after the diagnosis of SPMS. Disability worsening was assessed by the cumulative proportion of patients with a 6-month confirmed dis…
