It is still debated to what degree top-down and bottom-up driven attentional control processes are subserved by shared or by separate mechanisms. Interactions between these attentional control forms were investigated using a rapid event-related fMRI design, using an attentional search task. Following a prestimulus mask, target stimuli (consisting of a letter C or a mirror image of the C, enclos...
This study determined the effect of an integrated exercise program (coach and family) in three children with Down syndrome to Betterment their motor and cognitive capabilities, especially reaction time and working memory. For this purpose, the integrated exercise training program was applied in three children with Down syndrome, containing two boys (M1, with a chronologic age of 10.3 years and ...
در این کار تحقیقاتی، جذب گازهای آلاینده محیطی(co و co2) بر روی نانولوله تک دیواره،aln(4,4)، bn(5,5) و sic(4,4) با استفاده از تئوری چگالی و شرایط مرزی مورد مطالعه قرار گرفته شد. دو موقعیت جذب برای co، c-down و o-down، و یک موقعیت جذب برای co2، o-down، بر روی سه موقعیت مختلف نانولوله در نظر گرفته شد. برای هر موقعیت، نمودار انرژی پتانسیل بدست آمده با پتانسیلهای مورس و مورس تصحیح شده برازش شد. ساخ...
In recent years, surface water resources in Chaharmahal and Bakhtiari province have decreased and groundwater level has fallen down. Thus, groundwater must be strengthened by surface water resources. The objective of this search was identification of artificial recharge sites thorough Fuzzy Logic in Shahrekord Basin. Effective factors in ground water recharge such as slope, infiltration rate, t...
carbonate materials are mostly found in tropical areas, where exploiting gas and oil resources are of high concern. their unique behavior under shear loading first was recognised during oil resources investigations in the persian gulf. off-shore structures have been placed on carbonate soils which are highly crushable.during storms cyclic loading imposes on the bases of structures lied down on ...
Recent evidence has revealed that short-lived internal representations held in visual short-term memory (VSTM) can be modulated by top-down control via retrospective attention which impacts subsequent behavioral performance. However, the functional inter-regional interactions underlying these top-down modulatory effects are not fully characterized. Here we used event-related functional magnetic...
چکیده- خستگی عبارت است از پدیده ی شکست بر اثر تکرار بار، که تنش ایجاد شده توسط این بار ممکن است حتی به مراتب کوچک تر از مقاومت نهایی مصالح باشد .ترکهای ناشی از خستگی، در مقاطع آسفالتی، با توجه به مکان پیدایش و نحوه ی گسترش آنها دو دسته است .دستهی اول ترک هایی است که در بخش پایینی مقطع آسفالتی پدید می آیند و سپس با تکرار بار بهسمت بالا گسترش مییابند. پیدایش این نوع ترک ها در مقاطع آسفالتی با ضخا...
We report three cases of asymptomatic celiac disease identified in children with Down syndrome after being screened at around twenty-four months of age. These cases raise the question as to what age is screening for celiac disease indicated in a child with Down syndrome and no symptoms.
