: 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 اولBringing PIPs to root tips
iny hairs on Arabidopsis thaliana roots elongate via tip growth, in which new membrane is added specifically at the root hair tip. Vincent et al. (page 801) now show that a phosphatidylinositol transfer protein (PITP) related to yeast Sec14p is critical for this polarized growth, suggesting that PIP 2 may be the start of the polarity cascade in this system. The authors show that Arabidopsis has...
متن کاملChromosomal variation in man: catalog of chromosomal variants and anomalies.
Introducing a new hobby for other people may inspire them to join with you. Reading, as one of mutual hobby, is considered as the very easy hobby to do. But, many people are not interested in this hobby. Why? Boring is the reason of why. However, this feel actually can deal with the book and time of you reading. Yeah, one that we will refer to break the boredom in reading is choosing chromosoma...
متن کاملCharacterization of the hexose transport system in maize root tips.
Sugar-depleted excised maize (Zea mays L.) root tips were used to study the kinetics and the specificity of hexose uptake. It was found that difficulties induced by bulk diffusion and penetration barriers did not exist with root tips. Several lines of evidence indicate the existence of a complex set of uptake systems for hexoses showing an overall biphasic dependence on external sugar concentra...
متن کاملSeasonal Fluctuations in Growth Rates of Excised Tomato Root Tips.
Previous to 1934 ROBBINS (10, 11), ROBBINs and MANEVAL (12, 13), KOTTE (6, 7), CHAMBERS (1, 2), MALYSCHEV (8, 9), GAUTHERET (4, 5), and WHITE (14-17) had reported the cultivation of excised root-tips of various species of plants over periods in some cases as great as 5 months. In such of these studies as extended over considerable periods of time, the growth rates showed a more or less continuo...
