the qom formation in naragh area, with 185 meter thickness, is exposed about 25 km northeast of delijan. this formation in the studied area, lithologically, consists of shale, gravely limestone, and sandy limestone, with thin, medium to thick bedded and massive limestons. it disconformably covers the lower red formation and is covered by recent alluvium. in this research, the role of large fora...

As we tentatively proceed into this brave new teaching world of the 21 st century, much debate is centering on the effective teaching of English to young learners. Key to this discussion has been the role of the young learner syllabus. While this article makes reference to the teaching of English to young learners in an ESL context based on documentation developed within the European Union, the...

Speaking has been considered one of the most important skills in second language teaching and assessment. However, to date there has not been a clear definition of speaking ability. The present study attempts to examine what it means to be able to speak a second language using a newly designed computer-delivered speaking test. The test was created based on a theoretical definition of speaking a...

Reticence is a common problem faced by ESL/EFL teachers in classrooms, especially in those with mainly Asian students. The willingness to communicate model of MacIntyre, Clement, Dörnyei, and Noels (1998. ‘Conceptualizing willingness to communicate in a L2: a situational model of L2 confidence and affiliation’. The Modern Language Journal 82/4: 545–62.) postulates that willingness to speak is d...

shallowand deep-water acoustics. But during the cold war, the research emphasis shifted abruptly to deep water, where the ballistic missile submarine threat lurked (see box 1). After the cold war, the onset of regional conflicts in coastal countries shifted the focus again to shallow water. Those waters encompass about 5% of the world’s oceans on the continental shelves, roughly the region from...

Abstract A remarkably consistent Lagrangian upwelling circulation at monthly and longer time scales is observed in a 17-yr series of current profiles 12 m water on the southern New England inner shelf. The strongest summer, with magnitude ∼1 cm s −1 , which flushes shelf ∼2.5 days. average winter about one-half summer circulation, but larger month-to-month variations driven, part, by cross-shel...

Waves and tidal currents resuspend transport shelf sediments, influencing sediment distributions bedform morphology with implications for various disciplines including benthic habitats, marine operations, spatial planning. Shelf-scale assessments of wave-tide-dominance sand tend not to fully include wave-tide interactions, which nonlinearly enhance bed shear stress apparent roughness, change th...

Abstract Climate change has a pronounced effect on water resources in many semiarid climates, causing populated areas such as San Diego County (USA), to become more vulnerable shortages the coming decades. To prepare for decreased supply, is adopting policies decrease use and develop additional local sources of water. One new source freshwater produced by desalination facility that purifies bra...
