: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولSuccessive Cambia: A Developmental Oddity or an Adaptive Structure?
BACKGROUND Secondary growth by successive cambia is a rare phenomenon in woody plant species. Only few plant species, within different phylogenetic clades, have secondary growth by more than one vascular cambium. Often, these successive cambia are organised concentrically. In the mangrove genus Avicennia however, the successive cambia seem to have a more complex organisation. This study aimed (...
متن کاملWood and Stem Anatomy of Phytolaccoid and Rivinoid Phytolaccaceae (Caryophyllales): Ecology, Systematics, Nature of Successive Cambia
Quantitative and qualitative wood features are presented and analyzed for seven species of subfamily Rivinoideae and four of subfamily Phytolaccoideae. All species have nonbordered perforations plates, as elsewhere in suborder Phylocaccineae. Libriform fibers characterize both subfamilies, but vasicentric tracheids occur in two rivinoid species. Axial parenchyma is vasicentric scanty (apotrache...
متن کاملWood anatomy of Agdestis (Caryophyllales): systematic position and nature of successive cambia
Features in which Agdestis differs from Phytolaccaceae s. s. include presence of both libriform fibers and vasicentric tracheids (rather than one or the other); bands and strands of thin-walled apotracheal parenchyma (in addition to paratracheal scanty parenchyma}, and raylessness (also reported for Bougainvillea of Nyctaginaceae, a family close to Phytolaccaceae). Dimorphism in vessel diameter...
متن کاملOrigin of successive cambia on stem in three species of Menispermaceae1
(Origin of successive cambia on stem in three species of Menispermaceae). The lianas observed in this study, Abuta convexa (Vell.) Diels, Abuta imene (Mart.) Eichler, and Chondrodendron platiphyllum (A. St.-Hil.) Miers, all have successive cambia in their stems. The terminology applied to stem histology in species with successive cambia is as diverse as the interpretations of the origins of thi...
