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...

main purpose in this research is the explanation of different views of muslim philosophers on the p.f.c to establish an imperative religion education. reaching to this purpose we use the content analysis and logical deduction among the research methods. on the basis of the research findings, we can find two different approaches in the religious-intellectual education: popular and specialized. t...

the supremacy of adaptation and imitation of antecedents over innovation is one of the features of arab poetry after fall of abbasid dynasty. however, literary borrowing which is deliberate and combined with tastefulness and elegance yields an appropriate effect and association on readers. technically, in rhetoric, if a poet borrows a hemistich, a verse or some verses from others' poems as...

Coastal lagoons are a common land-margin feature worldwide and function as an important filter for nutrients entering from the watershed. The shallow nature of lagoons leads to dominance by benthic autotrophs, which can regulate benthic–pelagic coupling. Here we demonstrate that both microalgae and macroalgae are important in controlling dissolved inorganic as well as organic nitrogen (DIN and ...

We present I/O-efficient fully persistent B-Trees that support range searches at any version in O(logB n + t/B) I/Os and updates at any version in O(logB n + log2 B) amortized I/Os, using space O(m/B) disk blocks. By n we denote the number of elements in the accessed version, by m the total number of updates, by t the size of the query’s output, and by B the disk block size. The result improves...

Pe bza optimizarii detectorului fotodioda cu avalansa din sistemul EmiScopeTM utilizat pentru rezolvarea temporala a fotonilor, am realizat reducerea cu un factor mai mare de 2.5 a timpului de achizitie a semnalului emis în infrarosu de un tranzisttorCMOS. Efectul nedorit al pulsuirlor de zgomot generate de fotodioda la durate aleatorii fata de semnalul detectat a fost redus prin utilizarea înt...

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...
