DNA damage-inducible (din) genes in Bacillus subtilis are coordinately regulated and together compose a global regulatory network that has been termed the SOS-like or SOB regulon. To elucidate the mechanisms of SOB regulation, operator/promoter regions from three din loci (dinA, dinB, and dinC) of B. subtilis were cloned. Operon fusions constructed with these cloned din promoter regions rendere...

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...

We have identified many dark-inducible (din) genes that are expressed in Arabidopsis leaves kept in the dark. In the present study we addressed the question of how plant cells sense the depletion of sugars, and how sugar starvation triggers din gene expression in suspension-cultured cells of Arabidopsis. Depletion of sucrose in the medium triggered marked accumulation of din transcripts. Suppre...

Irrigated agriculture can modify the cycling and transport of nitrogen (N), due to associated water diversions, water losses, and changes in transport flow-paths. We investigate dominant processes behind observed long-term changes in dissolved inorganic nitrogen (DIN) concentrations and loads of the extensive (465,000 km2) semi-arid Amu Darya River basin (ADRB) in Central Asia. We specifically ...

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...

The pronounced increase in the cycling and deposition of biologically reactive dissolved inorganic nitrogen (DIN) over large areas globally not only cause increased concentrations of DIN in surface waters, but it will also affect nutrient ratios in rivers, lakes and coastal areas. This review addresses the flux and fate of DIN, focusing NO3 in lakes of boreal and alpine catchments. Not only DIN...

Abstract This article introduces Julius Heise’s Marche Triomphale which reveals a history that was eliminated during the nineteenth century race theory publications. Beginning with an account of Iranians’ encounters European military music, this provides brief Iranian bands in style, or muzikānchiān . It then addresses racial motivations behind short on music 1885 by Victor Advielle, French adm...

Receiving coastal waters and estuaries are among the most nutrient-enriched environments on earth, and one of the symptoms of the resulting eutrophication is the proliferation of opportunistic, fast-growing marine seaweeds. Here, we used a widespread macroalga often involved in blooms, Ulva spp., to investigate how supply of nitrogen (N) and phosphorus (P), the two main potential growth-limitin...
