Educational technology supports meaningful learning and enables the presentation of spatial and dynamic images, which portray relationships among complex concepts. The Technology-Enabled Active Learning (TEAL) Project at the Massachusetts Institute of Technology (MIT) involves media-rich software for simulation and visualization in freshman physics carried out in a specially redesigned classroo...
Coronavirus-like viruses, designated peafowl/China/LKQ3/2003 (pf/CH/LKQ3/03) and teal/China/LDT3/2003 (tl/CH/LDT3/03), were isolated from a peafowl and a teal during virological surveillance in Guangdong province, China. Partial genomic sequence analysis showed that these isolates had the S-3-M-5-N gene order that is typical of avian coronaviruses. The spike, membrane and nucleocapsid protein g...
هدف اصلی این تحقیق، ارائه مدلی برای نقش نهادهای میانجی در توسعه همکاری فناورانه بین بنگا ها است و در آن بخش هوافضایی کشور به عنوان مطالعه موردی انتخاب شده است.از نظر روش ،در این تحقیق از رویکرد ترکیبی کمی و کیفی استفاده شده است. بر این اساس، با بررسی ادبیات علمی موضوع و همچنین مطالعات اکتشافی گسترده برای عارضه یابی وضعیت موجود همکاری های فناورانه در این بخش، مدل مفهومی تحقیق طراحی شد که در آن د...
Experiments using live cell 3-color Förster (or fluorescence) resonance energy transfer (FRET) microscopy and corresponding in vitro biochemical reconstitution of the same proteins were conducted to evaluate actin filament nucleation. A novel application of 3-color FRET data is demonstrated, extending the analysis beyond the customary energy-transfer efficiency (E%) calculations. MDCK cells wer...
Highly pathogenic avian influenza (H5N8) virus, like the recently described H5N8 strain from Korea, was detected in November 2014 in farmed turkeys and in a healthy common teal (Anas crecca) in northeastern Germany. Infected wild birds possibly introduced this virus.
Local adaptation frequently occurs across populations as a result of migration-selection balance between divergent selective pressures and gene flow associated with life in heterogeneous landscapes. Studying the effects of selection and gene flow on the adaptation process can be achieved in systems that have recently colonized extreme environments. This study utilizes an endemic South American ...
Observations were made of birds and mammals on Adams Island and the southern end of the main Auckland Island between 2 November and 7 December 1989. Thirty-five bird species, fur seals and sealions were observed. Five Auckland Island rail were captured and many more heard on Adams Island. Counts of wandering and royal albatross, yellow-eyed penguins, Auckland Island teal and Auckland Island dot...
Speciation is a process in which genetic drift and selection cause divergence over time. However, there is no rule dictating the time required for speciation, and even low levels of gene flow hinder divergence, so that taxa may be poised at the threshold of speciation for long periods of evolutionary time. We sequenced mitochondrial DNA (mtDNA) and eight nuclear introns (nuDNA) to estimate geno...
هدف پژوهش حاضر بررسی عناصر چیره‌دستی سازمانی در سازمان‌های علمی و فناورانه است. پژوهش حاضر از دسته پژوهش‌های توصیفی به‌شمار می‌رود که به روش پیمایش اجرا می‌شود. در این پژوهش مدل چیره دستی سازمانی از نظر کمی آزمایش شده است. جامعۀ آماری از میان شرکتهای فعال علمی و فناورانۀ جهاد دانشگاهی انتخاب شده است، به‌طوری که این شرکتها بیش از 10 نفر کارمند و 5 مدیر دارند و 94 شرکت را دربرمیگیرد. با توجه ب...
