The extent of aluminium internalization during the recovery from aluminium stress in living roots of Arabidopsis thaliana was studied by non-invasive in vivo microscopy in real time. Aluminium exposure caused rapid depolarization of the plasma membrane. The extent of depolarization depends on the developmental state of the root cells; it was much more extensive in cells of the distal than in th...

Pragmatic competence is one of the most important components of successful communication; also, it is the most difficult aspect of SLA. This study aimed to explore the effects of concurrent group dynamic assessment (G-DA) on Iranian EFL learners’ learning of requests and refusals, following a mixed method design. In the experimental part of the study, 2 intact classes were homogenized by a pret...

With the latest paradigm shift in SLA from Cognitivism to Sociocultural Theory (SCT), more studies are carried out to investigate the efficacy of Written Corrective Feedback (WCF) through a social and cultural lens. A more recent offspring of SCT is Activity Theory which provides an explanatory framework for scrutinizing an activity in a social setting. The present study aimed at investigating ...

Abscission zone tissue of citrus was shown to have a higher rate of protein synthesis than tissue distal or proximal to it, based on the incorporation of leucine-1-(14)C. The proximal tissue had the slowest rate of protein synthesis. As the tissue approached abscission, the rate of synthesis in the abscission zone decreased and the differences in rate of protein synthesis between the 3 zones al...

BACKGROUND Retrograde type A aortic dissection (RTAD) is a potentially lethal complication after thoracic endovascular aortic repair (TEVAR). However, data are limited regarding the development of RTAD post-TEVAR. This systematic review aims to define the incidence, mortality, and potential risk factors of RTAD post-TEVAR. METHODS AND RESULTS Multiple electronic searches were performed. Fifty...

The development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. In Petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. Studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. In this study, which is a...

The educational concept of “Zone of Proximal Development”, introduced by Vygotskij, stems from the identification of a strong need for adaptation of the learning activities, both traditional classroom and modern e-learning ones, to the present state of learner’s knowledge and abilities. Furthermore, Vygotskij’s educational model includes a strong bent towards social and collaborative learning. ...

Borders have significant potential as tourist attractions, and there are many aspects of unique border locations capable attracting people’s attention. One such attraction would be the tripoint, i.e. a place where borders three different countries meet physically at single point. newest features in Europe – Poland, Slovakia Czechia Beskid Mountains provides an example far-reaching border-relate...
