‏‎translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...

Pollination is an ecological service with high economic values related to human and ecological wellbeing. This study aims to evaluate the correlation between landscape complexity and pollination service (bee) in Qazvin province at the landscape scale. Landscape pattern metrics (Number of Patches (NP), Patch Richness (PR), Edge Density (ED), and Shannon Index (H)), as a proxy of landscape comple...

The aim of this research was to compare the rangelands structure and landscape degradation in Iril sub-watersheds, Ardabil province. Land use map and the Landscape Fragmentation Tool were used to determine 4 classes of patch, edge, perforated and core through 5, 10, 15 and 20m cell sizes. The landscape metrics of LPI, ED, cohesion, mesh, split, and AI were calculated using Fragstats software. R...

In this paper, the effects of spatial grain size on landscape pattern of Qingpu district are discussed under two levels of class and landscape. To reveal the effects of grain size on landscape pattern, a series of rastergraphs with different grid cells are constructed based on majority rules using data of TM satellite remote sensing and GIS skills. Software Grid module of Arc/Info Fragstats3.3 ...

abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...

As special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. Geomorphic features of deltas are in constant transformation due to their dynamic features. Constructing dams on rivers can intensify these changes and cause either negative or positive consequences. Minab delta in Hormozgan Province of Iran is a round or crescent-s...

1. introduction environmental changes can be monitored at many scales but the scale of landscape and region has more information in support of sustainable spatial planning. the availability of remote sensing imagery provides multi-scale observation with periodic repetitions over time. landscape and regional scales are adequately covered by satellite images. remote sensing images provide non-ave...

Landscape ecology as a modern interdisciplinary science offers new concepts, theories, and methods for land evaluation and management. One main part of landscape ecology is describing patterns in the landscape and interpreting the ecological effects of these patterns on flora, fauna, flow of energy and materials. Landscape studies require methods to identify and quantify spatial patterns of lan...

Knowledge about long-term land cover/use changes is essential for evaluating and predicting their consequent problems by urban managers and policymakers. Remote sensing with landscape metrics is an effective tool for monitoring these changes in urban cores and their peripheral areas. During the recent decades, industrial and urban growth, and immigration of people into Isfahan metropolitan area...
