Phenology is the study of time and sequence of recurring stages in the life history of an organism. The occurrence fashions of the phenophases form different phenological behavior patterns. Despite the importance of phenology and wide applications of knowing phenophases, few studies have been done on the wooden species in Iran. The goals of this study are identification and designation of the p...
STUDY QUESTION Is it possible to detect associated deep infiltrating endometriosis (DIE) before surgery for patients operated on for endometriomas using a preoperative clinical symptoms questionnaire? SUMMARY ANSWER A diagnostic score of DIE associated with endometriomas using four clinical symptoms defined a high-risk group where the probability of DIE was 88% and a low-risk group with a 10%...
Rectangular waveguide is one of the earliest types of transmission lines. Rectangular waveguide can be produced by hot extrusion process. In this paper, the hot extrusion process of CuZn5 rectangular waveguide was investigated by Finite Element Method (FEM). In addition, Genetic Algorithm (GA) was used to optimize the die geometry and process conditions to achieve the lowest magnitude of extrus...
the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
In diesem Artikel wird eine pragmatische Abwandlung der didaktischen Methode des LearnTeamCoaching von Fleischmann et. al., vgl. (Fleischmann u. a., 2003), vorgestellt. Diese Methode aus dem Repertoire des Inverted Classroom ermöglicht den Studierenden ein individuelles Lernen. In drei aufeinanderfolgenden Phasen erarbeiten sich die Studierenden ein Thema selbständig (Lernen), diskutieren und b...
Der XO-Laptop ist mit einer Palette von Werkzeugen ausgestattet, die das Bearbeiten multimedialer Komponenten erlauben (Texte, Bilder, Videos), den Zugang zum Internet eröffnen und kollaboratives Arbeiten unterstützen. Ebenfalls enthalten sind mehrere Entwicklungsumgebungen zum Programmieren. Da die Adressaten primär Grundschüler sind, ist es nicht verwunderlich, dass dabei Anleihen bei der Pro...
aim : to determine the prevalence of gastrointestinal symptoms and signs among persons with diabetes mellitus in a specialist hospital. background : gastrointestinal symptoms and signs are common among patients with diabetes mellitus. morbidity from patients and methods : in this descriptive, cross-sectional study, subjects from the general population with diabetes (n=200) were recruited for th...
Der Trend zu verteilter Projektarbeit, als auch der Trend zu kleinteiliger, kontinuierlich weiterentwickelter Software1 verstärken die Notwendigkeit Softwarewerkzeuge schnell und flexibel in den lokalen Kontext von Arbeitsgruppen zu integrieren. Dies stellt neue Anforderungen an Provisioning-Werkzeuge (Wolf 2003; Gerlach, Güven et al. 2007; Reiswich 2008), welche die Bereitstellung, Konfigurati...
recent years have witnessed an increased attention to form focused instruction and consciousness raising activities (ellis, 2002; doughty & williams, 1998) on the one hand and extensive and meaningful exposure to the target language (klapper & rees, 2003; day & bamford, 1998) on the other. due to significance attributed to above mentioned issues by scholars, this study attempted to bridge them ...
In this paper, an upper bound approach is used to analyze the extrusion process of bimetallic rods through arbitrarily curved dies. Based on a spherical velocity field, internal, shearing and frictional power terms are calculated. The developed upper bound solution is used for calculating the extrusion force for two types of die shapes: a conical die as a linear die profile and a streamlined di...
