Methods of storing, managing and presenting educational multimedia data are proposed. Application of these methods to interactive synchronous and asynchronous Distance Learning systems is discussed. An example system based on the proposed solution is presented in details. The system uses clean organization of educational material and enables storage, management, and presentation of various type...

We often eat heat-coagulated (H-C) food proteins, but there have been few studies on the allergenic activity of H-C proteins after digestion and absorption in vivo. To show that H-C protein is not an allergen after digestion, mice were used to investigate the digestion and absorption of the protein through the intestinal epithelium into portal blood employing immunoblotting and competitive inhi...

In this paper we describe the ongoing work on the Circumstantial Event Ontology (CEO), a newly developed ontology for calamity events that models semantic circumstantial relations between event classes, where we define circumstantial as explicit and implicit causal relations. The circumstantial relations are defined manually in the ontology for classes of events that involve a change to the sam...

A preconcentration/separation procedure is presented for the solid phase extractionof trace cadmium and lead ions as their 2-propylpiperidine-1-carbodithioate (PPCD) chelates inenvironmental samples on Nano Graphene, prior to cadmium and lead determinations by atomicabsorption spectrometry. The preconcentration procedure was optimized by using model solutionscontaining c...

statement of the problem generally, the main source of fluoride intake is drinking water. excessive consumption of bottled water as a substitute or in addition to the tap water supply may have implications for safe fluoride supplementation. in this study, fluoride contents in six commercial brands of bottled water were measured materials and methods six different brands of bottled drinking wate...

The purpose of this study is to investigate the conceptual content term “quality” in higher education, as it emerges from descriptions and discussions authors, researchers, experts 22 scientific publications. analysis qualitative data based on methodology grounded theory. From analysis, 21 major dimensions or characteristics quality education emerged due their high frequency...

[1] Gas phase miscible displacement experiments were conducted to quantitatively investigate the advective and dispersive contributions to gas phase transport in unsaturated porous media over a range of soil water contents. Furthermore, the independence of measured dispersivity values was evaluated through comparison of nonreactive and reactive tracer transport. Methane was used as a nonreactiv...

1. Previous work has suggested that living cells may acquire and then maintain different water contents and hence volume, in solutions containing different concentrations of solutes that are permeant to the cell membrane. Toward better understanding of this phenomenon, two hypotheses were introduced: one hypothesis is based on the membrane-pump theory; another represents an extension of the pol...
