1 "SINK" = C[ 34 + n(O( D» .K5] RN20 (1) Abstract. A numerical simulation of atmospheric NZO using the GFDL 3-D tracer model with a small uniform surface source (15 Mton yr-1) and stratospheric destruction (150 yr lifetime) has been run to a state near transport and chemical statistical equilibrium. The resulting NZO tropospheric distribution is relatively uniform with a slight excess in the So...
in this paper we obtain lower and upper estimates for the essential norms of generalized composition operators from weighted dirichlet spaces or bloch type spaces to $q_k$ type spaces.
objective: several studies have compared ferric sulfate and formocresol pulpotomy in primary molars. the results of these studies, however, could not be compared due to differences in evaluated outcomes (clinical, radiographic, or histologic) and follow up duration. the aim of the present study was a systematic review of similar studies and a metaanalysis of their results to provide the latest ...
This paper examines the impact of regulatory intervention to cut termination rates of calls from fixed lines to mobile phones. Under quite general conditions of competition, theory suggests that lower termination charges will result in higher prices for mobile subscribers, a phenomenon known as the “waterbed” effect. The waterbed effect has long been hypothesized as a feature of many two-sided ...
roid stimulating hormone in patients with Graves' disease is postulated by Purves and Adams. A similar lack of dependence on TSH is described by I. Doniach during rapid growth of the infantile thyroid and the compensatory hypertrophy of thyroid remnants after thyroidectomy. Interrelations of TSH and ACTH are correlated by Brown-Grant. His observations include the effects on thyroid activity of ...
the main purpose of the present study was to investigate the relationship between listening proficiency and metacognitive listening strategies awareness among low, mid, and highly self-regulated students. three hundred and seventy one efl students participated in this study (all grade 3 and 4 high-school students who were studying in khansar in academic year 1391-92). to gather the data, three ...
روش مقاومت ویژه یکی از مهمترین روشهای الکتریکی است که به آشکارسازی ناهمگنی و ناهمسانگردی به ویژه در اعماق کم می پردازد از این روش همچنین برای تشخیص امتداد ساختارهای زیر سطحی استفاده می شود در این مورد ، وجود ناهمگنی و ناهمسانگردی هایی که هدف اصلی اکتشاف نیستند بر داده ها اثر گذاشته و موجب تفسیر نادرست می شوند برای پرهیز از این مشکل باید از روش هایی استفاده شود که بیشترین حساسیت را نسبت به آشکار...
