this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
One of the main problems experienced by the islanders of Lakshadweep is associated with the availability of fresh water for drinking purpose. The scarcity of fresh water is due to the peculiar hydrologic, geologic, geomorphic and demographic features. Proper understanding of the groundwater condition, in terms of availability, distribution and quality, is very important to meet the increasing d...
Cave entrances directly connect the surface and subsurface geomorphology in karst landscapes. Understanding spatial distribution of these features can help identify areas on landscape that are critical to flow groundwater system. Sinkholes springs major locations inflow outflow from system, respectively, however not all sinkholes equally connected main conduit Predicting where zones high connec...
Gypsiferous Aridisols are of great importance and extent in arid and semi-arid environments. There is a close relationship between soil genesis and landscape positions. This study aimed to determine the genesis and classification of gypsiferous soils and to investigate the relationship between micro-and macro-morphology of gypsum crystals and geomorphic positions in Rafsanjan area. The study ar...
Introduction: Recent results from gamma-ray and neutron spectrometers on Mars Odyssey indicate the presence of a hydrogen-rich layer tens of centimeters thick in the uppermost meter in high latitudes (>60 ̊) on Mars [1]. This hydrogen-rich layer correlates to regions of ice stability [2]. Thus, the subsurface hydrogen is thought to be water ice constituting 35+/15% by weight near the north and s...
Unintended Consequences of Urbanization for Aquatic Ecosystems: A Case Study from the Arizona Desert
H and geomorphology are important determinants of the structure and function of fluvial ecosystems. Streamflow quantity and timing are often viewed as “master variables” limiting the distribution and abundance of riverine species (Poff et al. 1997) and the flux of nutrients into streams (Grimm 1987, Welter et al. 2005). Geomorphic structure—particularly channel form—is known to influence commun...
with the growth of more humanistic approaches towards teaching foreign languages, more emphasis has been put on learners’ feelings, emotions and individual differences. one of the issues in teaching and learning english as a foreign language is demotivation. the purpose of this study was to investigate the relationship between the components of language learning strategies, optimism, duration o...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
