سازند پابده در برش دره شهر شامل 260متر شیل، شیل آهکی، مارن و آهک می باشد. مطالعات انجام شده بر روی فرامینیفرهای پلانکتون منجر به شناسایی و ارائه تعداد 12 بیوزون شده است. این بیوزون ها عبارتند از: بیوزون شماره یک: parasubbotina pseudobulloides partial-range zone ، بیوزون شماره دو: subbotina triloculinoides partial-range zone، بیوزون شماره سه: morozovella angulata partial-range zone ، بیوزون شمار...
An educational intervention was implemented at the University of Michigan starting in 2008, in which anesthesiology interns complete a dedicated month-long didactic rotation in evidence-based medicine (EBM) and research methodology. We sought to assess its utility. Scores on a validated EBM test before and after the rotation were compared and assessed for significance of improvement. A survey w...
A new gaseous active target based on a time projection chamber, named CAT, is introduced. The remarkable feature is a dual gain THGEM to decrease the effective gain for the beam particles while keeping a high enough effective gain for the recoil particles. The measured effective gain of low gain region was a factor of one hundred smaller than that of high gain region. This technique provides a ...
We report the first practical results on design and characterization of adaptive microbolometers with a thermally tuned responsivity. Such devices are needed to simultaneously image scenes that contain objects at ambient and extremely hot temperatures. In the high detectivity state, the microbolometers are operated similar to standard commercial devices. In the low detectivity state, portions o...
