This paper will report on lessons learned from two studies using blended learning courses involving past and present experience of the authors. Will also discuss the importance of online asynchronous discussions in the teaching and learning process. The paper concludes with suggested guidelines for the use of asynchronous online discussions, considered useful for instructors who teach for the f...

Endometriosis is classically defined as the growth of endometrial glands and stroma at extra-uterine sites, most commonly implanted over visceral and peritoneal surfaces within the female pelvis (1). Though endometriosis has been described for the first time in 1690 by the German physician, Daniel Shroen, researchers remain still unsure as to the definitive cause of this disease (2). The most w...

Transformatoarele de putere de înaltă tensiune reprezintă unele din cele mai costisitoare echipamente din staţiile electrice din sistemul electroenergetic. Defectele şi opririle accidentale ale acestora nu cauzează numai costuri cu reparaţiile; ele conduc şi la pierderi ecomonice datorate întreruperii alimentării consumatorilor. Testele preventive şi monitorizarea on-line sunt benefice pentru p...

Water originating from coal-bed natural gas (CBNG) production wells typically contains ammonium and is often disposed via discharge to ephemeral channels. A study conducted in the Powder River Basin, Wyoming, documented downstream changes in CBNG water composition, emphasizing nitrogen-cycling processes and the fate of ammonium. Dissolved ammonium concentrations from 19 CBNG discharge points ra...

We investigated the properties of an artificial chimeric peptide that contains an Arg-Gly-Asp (RGD)tripeptide, the versatile cell recognition signal of extracellular matrix protein components, coupled to a carboxyl-terminal fragment of the highly specific a-thrombin hibitor, hirudin (residues 53-64): WG-SANGDFEEIPEEYL (RGD-hir~din'~-'~). Hir ~ d i n ~ ~ ' ~ and RGD-hir~din'~-'~ inhibited th...

Incidental ingestion of household dust is an important arsenic (As) exposure pathway for children. However, compared to soils, assessment of As relative bioavailability (RBA) in household dust is limited. In this study, As-RBA in 12 household dust samples (7–38 mg kg(–1)) was measured using an in vivo mouse model and compared to As bioaccessibility determined using 4 assays [Solubility Bioacces...

Availability and leaching of dissolved inorganic N (DIN = NH4 + NO3) in soil were measured in a periodically flooded forest of the Central Amazon floodplain (v rzea) during one terrestrial phase. Special emphasis was on the effects of a legume and a nonlegume tree species. NH4-N accounted for more than 85% of DIN even at the end of the terrestrial phase although it decreased throughout the expe...

This paper describes a spelling correction system that functions as part of an intelligent tutor that carries on a natural language dialogue with its users. The process that searches the lexicon is adaptive as is the system filter, to speed up the process. The basis of our approach is the interaction between the parser and the spelling corrector. Alternative correction targets are fed back to t...
