SIERRa is a program that learns procedures incrementally from examples, where an example is a sequence of actions. StERRA learns by completing explanations. Whenever the current procedure is inadequate for explaining (parsing) the current example, SIERRA formulates a new subprocedure whose instantiation completes the explanation (parse tree). The key to SIERRA'S success lies in supplying a smal...
an experiment was conducted to examine the effect of different levels of extruded soybean and enzyme on broiler performance. in a completely randomized design with 2×3 factorial arrangement, 480 one day-old, ross broiler chickens were divided into 40 groups, 12 chicks per pen. treatments were consisting of combination of four levels of extruded soybean (0.0, 5.0, 10.0 and 15.0 %) and two levels...
abstract this study investigates the teachers’ correction of students’ spoken errors of linguistic forms in efl classes, aiming at (a) examining the relationship between the learners’ proficiency level and the provision of corrective feedback types, (b) exploring the extent to which teachers’ use of different corrective feedback types is related to the immediate types of context in which err...
In 2005 a Mycobacterium genavense infection was diagnosed in one blue-headed parrot (Pionus menstruus) imported from Surinam (South America), the first such incidence in the Czech Republic. The bird died suddenly. Histopathological examination revealed a diffuse granulomatous inflammatory reaction in the intestinal mucosa. Tissue sections of the intestines stained by Ziehl-Neelsen were microsco...
To investigate the effects of D-penicillamine (D-Pen) on angiogenesis, we have studied the effects of this drug on in vitro proliferation of human endothelial cells (EC) and in vivo corneal neovascularization. D-Pen, in the presence of copper sulfate, suppressed tritiated thymidine ([3H]TdR) incorporation into EC in a dose-dependent manner. Significant inhibition was observed with D-Pen concent...

esl/efl books play a crucial role in shaping language learners worldview of gender roles in society. the present study investigated the status of sexism in two sets of efl textbooks, one developed by non-native iranian authors (ili series) and the other by native authors (top notch series). first, two books from each series was selected randomly. then, a quantitative analysis was carried out wi...
Our objectives were to describe and test refined procedures for quantifying excreta produced from whole pens of dairy heifers. Previous research efforts attempting to make whole-pen measurements of excreta output have been complicated by the use of organic bedding, which requires cumbersome analytical techniques to quantify excreta apart from the bedding. Research pens equipped with sand-bedded...
The present study was designed to analyze the growth performance, behavioral patterns and intensity of injuries of weaned pigs (26 days) during a rearing period of 6 weeks. The farrowing system (group housing (GH) v. single housing (SH)) and the post-weaning regrouping weight class (light, medium, heavy) were considered as the main factors. A number of 120 GH-pigs and 120 SH-pigs were kept in t...
Two minisatellite loci from a Eurasian songbird, the willow warbler (Phylloscopus trochilus) were isolated, sequenced and used as probes to detect more than 20 related hypervariable loci. In addition, a sequence flanking one of the minisatellite loci was isolated, and used to study a VNTR locus. The bird minisatellites have a repeat unit of either 12 (AGGGAAGGGCTC) or 17 bp (GGGGACAGGGGACACCC),...
