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...

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 ...

Salicylate-containing herbs have been used as analgesic and anti-inflammatory remedies from ancient times. In this work we performed a comparative HPLC study of salicylic derivatives in three natural products: Salicis cortex, Populi gemmae and Ulmariae folium. We have identified and measured by a new, easy and fast HPLC method both salicylic acid and salicin, before and after acid hydrolysis, i...
