The goal of the current study was to investigate the effects of an immersive virtual reality (IVR) science simulation on learning in a higher educational setting, and to assess whether using self-explanation has benefits for knowledge gain. A sample

Immersive virtual reality (IVR) simulations for education have been found to increase affective outcomes compared to traditional media, but the effects on learning are mixed. As reflection has previously shown to enhance learning in traditional media

This volume constitutes the first anthology of texts in cognitive semiotics - the new transdisciplinary study of meaning, mind and communication that combines concepts and methods from semiotics, cognitive science and linguistics - from a multitude o

We review literature on the metabolism of ribo- and deoxyribonucleotides, nucleosides, and nucleobases inEscherichia coliandSalmonella,including biosynthesis, degradation, interconversion, and transport. Emphasis is placed on enzymology and regulatio

xapABR from Salmonella enterica was analyzed and compared with the corresponding Escherichia coli genes. xapB and xapR , but not xapA , encode functional proteins. An S. enterica XapA(Asp72Gly) mutant that restores the phosphorolytic activity was sel

Salmonella enterica serovar Typhimurium normally salvage nucleobases and nucleosides by the action of nucleoside phosphorylases and phosphoribosyltransferases. In contrast to Escherichia coli, which catabolizes xanthosine by xanthosine phosphorylase

Dihydroorotate dehydrogenase (DHOD) (EC 1.3.3.1) from the thermoacidophilic archaeon Sulfolobus solfataricus P2 (DSM 1617) was partially purified 3,158-fold, characterized, and the encoding genes identified. Based on enzymological as well as phylogen

The specificity of XapB permease was compared with that of the known nucleoside transporters NupG and NupC. XapB-mediated xanthosine uptake is abolished by 2,4-dinitrophenol and exhibits saturation kinetics with an apparent K m of 136 μM. A 12-trans

The interoperator distance between a synthetic operator Os and the deoP2O2-galK fusion was varied between 46 and 176 bp. The repression of the deoP2 directed galK expression as a function of the interoperator distance (center-to-center) was measured

Purine nucleoside phosphorylases (PNPs, E. C. 2.4.2.1) use orthophosphate to cleave the N-glycosidic bond of beta-(deoxy)ribonucleosides to yield alpha-(deoxy)ribose 1-phosphate and the free purine base. Escherichia coli PNP-II, the product of the xa
