Lesion Segmentation in Breast Sonography
2010
Sonography is gaining popularity as an adjunct screening technique for assessing abnormalities in the breast This is particularly true in cases where the subject has dense breast tissue, wherein widespread techniques like Digital Mammography (DM) fail to produce reliable outcomes This article proposes a novel and fully automatic methodology for breast lesion segmentation in B-mode Ultra-Sound (US) images by utilizing region, boundary and shape information to cope up with the inherent artifacts present in US images The proposed approach has been evaluated using a set of sonographic images with accompanying expert-provided ground truth.
Growth rates of late Miocene corals from Crete (Greece)
2006
Modern scleractinian corals are classical components of marine shallow warm water ecosystems. Their occurrence and diversity patterns in the geological record have been widely used to infer past climates and environmental conditions. Coral skeletal composition data reflecting the nature of the coral environment are often affected by diagenetic alteration. Ghost structures of annual growth rhythms are, however, often well preserved in the transformed skeleton. We show that these relicts represent a valuable source of information on growth conditions of fossil corals. Annual growth bands were measured in massive hemispherical Porites of late Miocene age from the island of Crete (Greece) that …
Detection of disbonds in multilayer structures by laser-based ultrasonic technique
2008
Adhesively bonded multi-layer structures are frequently used, mostly in the aerospace industry, for their structural efficiency. Nondestructive evaluation of bond integrity in these types of structures, both after manufacturing and for periodic inspection during service, is extremely important. A laser-based ultrasonic technique has been evaluated for non-contact detection of disbonds in aluminum multi-layer structures. Two configurations have been used to detect disbonded areas: pitch-catch with unidirectional guided wave scan and through-transmission with bidirectional scan. Guided wave scanning was done with a laser line source and air-coupled transducer sensing at 500 kHz, 1 ;MHz, and 2…
Vergleich der subcellulären Verteilung von 3H-Strophanthin und 3H-Digi-toxin im Meerschweinchenherzen / Comparison of the Subcellular Distribution of…
1969
Um Aufschlus uber den Wirkort von Herzglykosiden in der Herzmuskelzelle zu erhalten, wurde die subcellulare Verteilung von 3H-Digitoxin und 3H-Strophanthin untersucht und mit dem positiv inotropen Effekt verglichen. Meerschweinchenherzen wurden nach der Langendorff-Methode mit glykosidhaltiger Tyrodelosung (3 · 10−7 bzw. 2,8 · 10−7 g/ml; 37°C) perfundiert; die Kontraktionskraft wurde fortlaufend isotonisch registriert. Die Glykosidkonzentration in den einzelnen Fraktionen wurde nach Homogenisation, Differentialzentrifugation und Extraktion der Glykoside mit Toluol bzw. Dioxan mit einem Flussigkeitsszintillations-zahlgerat bestimmt. Die Ruckverteilung wahrend der Aufarbeitung wurde in Kontro…
Digital Storytelling Project as a Way to Engage Students in Twenty-First Century Skills Learning
2020
[EN] This paper is focused on the implications of a collaborative digital storytelling project on student engagement in the higher education context. The empirical study is conducted with an interdisciplinary group of bachelor students in a Nordic University (N = 22) and a university in Southern Europe (N = 21), and the data are collected through an online student survey. The results demonstrate that the digital storytelling project supported students’ behavioral, emotional, and cognitive engagement. In general, the students had positive emotional experiences with the project. This assignment format was found less stressful than a frontal presentation in the classroom, allowing the students…
Meningitis carcinomatosa con pleocitosis polimorfonuclear como forma de presentación de un adenocarcinoma gástrico
2003
Bilaterale Nierenrindennekrosen im Rahmen eines Sanarelli-Shwartzman-Ph�nomens nach Pneumokokkenmeningitis bei chronisch-essentieller Erythroblastope…
1966
Es wird uber den Verlauf einer chronisch-essentiellen Erythroblastopenie (sog. Blackfan-Diamond-Anamie) bei einem 4 Jahre, 11 Monate alten Madchen berichtet. Dabei erweckten die lange Verlaufsdauer, die Therapie sowie deren Komplikationen besonderes Interesse, wobei wir der interkurrenten Meningokokken-Meningitis sowie der todlichen Pneumokokkenmeningitis in Verbindung mit Anurie, hamorrhagischer Diathese und Kreislaufkollaps besondere Bedeutung beimasen. Pathologisch-anatomisch wurden Organveranderungen gefunden, die sich einem Sanarelli-Shwartzman-Phanomen zuordnen liesen. Dabei standen bilaterale Nierenrindennekrosen, die Verstopfung kleiner Nierenrindengefase sowie der Glomeruluscapilla…
Über eine Nebenwirkung von Herzglykosiden auf die Viskosität des Blutes
1964
Die Strukturviskositat und Thixotropie von menschlichem Blut wird durch zugesetzte Herzglykoside (k-Strophanthin, Digitoxin) erniedrigt. Dieses Phanomen unterstutzt die Wirkung der Herzglykoside am Herzen.

Antifeminismo y troleo de género en Twitter. Estudio de la subcultura trol a través de #STOPfeminazis
2020
espanolEn los ultimos anos, el auge del movimiento feminista, especialmente desde la convocatoria del 8M de 2018, se ha encontrado con resistencias importantes. En el ambito digital, esta renovacion del feminismo ha supuesto un aumento del activismo digital feminista y una mayor visibilidad de las mujeres. Sin embargo, tambien han surgido multiples obstaculos que muestran el caracter androcentrico y misogino de la cultura digital. Uno de los fenomenos asociado a la misoginia digital es el “troleo de genero” (gendertrolling), propio de la subcultura troll. En este trabajo, analizaremos el troleo antifeminista en la plataforma Twitter, centrandonos en la etiqueta #STOPfeminazis. A partir del …
