In the literature students are sometimes assumed to feel empowered with respect to learning because of their familiarity with and access to ICT. However, after interviewing 25 students from post-elementary schools, it was found that the majority of the students, although they use the Internet and other ICT for school purposes, believed that their generation is not as good at learning as the pre...

For startup firms, innovation is their main modus operandi. At the organizational level, they are digital natives, birthed in the era of digital business models. Well-established, traditional businesses, however, face a unique set of challenges in introducing digital business models: how can they balance “keeping the lights on” with an existing non-digital business model while concurrently comm...

The digital generation has many names: Net Generation, Generation@ or Digital Natives. The meaning behind these terms is, that the current generation of students is digitally and media literate, technology-savvy and are able to use other learning approaches than former generations. But these topics are discussed controversial and even the cause-effect-relationship is not as clear as it seems. D...

1. The ability of N- and C-terminal half-molecule fragments of hen ovotransferrin to interact with chick red blood cells (CERBC) has been studied under conditions that allow binding of the transferrin to transferrin receptors to take place, but not the delivery of iron to the cell. Two kinds of half-molecule fragments were used: (a) those which can associate with one another to give a dimer res...

Amyloid fibrils are associated with numerous degenerative diseases. The molecular mechanism of the structural transformation of native protein to the highly ordered cross-beta structure, the key feature of amyloid fibrils, is under active investigation. Conventional biophysical methods have limited application in addressing the problem because of the heterogeneous nature of the system. In this ...

We describe here the G12 pro-B cell clone that has been isolated from an IL-7 transgenic mouse. This clone has the phenotype B220+, BP-1+, HSA+, CD43+, lambda5+, and CD25-, and has its Ig locus in a germline configuration. G12 cells spontaneously express cell-surface MHC class II molecules, although to a much lesser extent than the mature M12.4.1 B-cell lymphoma. G12 cells can process and prese...

An attempt to enhance the transglycosylation activity of lysozyme -'as made by chemical modification. Computer simulation of the Iysozyme-catalyzed reaction indicated that inhibition of the sugar residue binding te the binding subsite A caused a significant increase in transglycosylation activity. Therefore, the binary modification of Asp 1O1 and Trp 62 in hen egg white lysezyme was made in ord...

The aim of this study is to model the growth samples four varieties (White, Black, Partridge, Franciscan) Spanish Utrerana hen breed, which endangered, by using Brody, Von Bertalanffy, Verhulst, Logistic and Gompertz models. For purpose, a total 16,235 weight data observations from 2004 animals reared in free range system were collected. was best suited for predicting biological curve White var...

The secreted yield of hen egg-white lysozyme (HEWL) from the filamentous fungus Aspergillus niger was increased 10-20-fold by constructing a novel gene fusion. The cDNA sequence encoding mature HEWL was fused in frame to part of the native A. niger gene encoding glucoamylase (glaA), separated by a proteolytic cleavage site for in vivo processing. Using this construct, peak secreted HEWL yields ...
