In this fMRI study, students learned to solve algebra-like problems in one of the four instructional conditions during behavioral session and solved transfer problems during imaging session. During learning, subjects were given explanatory or non-explanatory verbal instruction, and examples that illustrated the problem structure or the solution procedure. During transfer, participants solved pr...

As a key element in the semiconductor industry, efficient and stable transfer of the wafer set the very high request to the wafer transfer manipulator.At present,wafer transfer robot(SCARA-type,R-θ type) widely used in IC manufacturing equipment can only realize translational transmission to wafer,can not realize the posture change.So wafer transfer acceleration can only rely on its own gravity...

The nature of a H-transfer in the thymidylate synthase catalyzed reaction was investigated by comparison of the wild-type enzyme with the W80M mutant. The nature of the H-transfer was not affected, as indicated by intrinsic isotope effects and their temperature dependence. These findings support a single-step hydride transfer instead of a two-step radical transfer.

We examined the potential vulnerabilities of pilots flying a mixed fleet of two different aircraft types. A “worst case” scenario was evaluated in which a pilot, flying one type exclusively, would need to fly the different type, after 6 months without any recurrency training on the latter. These circumstances invite negative transfer of habits in the “old” aircraft, to performance in the “new” ...

We examine theoretically resonant non-radiative exciton (Förster) transfer in the system of colloidal coreshell quantum dots (QDs) of different types. We show that when the type-I QD (acceptor) is coupled with the type-II QD (donor), the electron-hole pair optically excited in the type-II QD can be transferred to the type-I QD nonradiatively, if the recombination time of the former is larger th...

GUINEA PIGS SENSITIZED WITH TUBERCLE BACILLI DEMONSTRATE A DUAL ALLERGIC RESPONSE MEDIATED BY TWO CHEMICALLY DISTINCT PLASMA FRACTIONS: 1. Antibody to tuberculopolysaccharide is located exclusively in fraction II (gamma globulin). This fraction will passively transfer systemic anaphylaxis and urticarial type skin reactivity to tuberculopolysaccharide, and contains the Middlebrook-Dubos antibody...

We recorded fluorescence time traces, and simultaneously either the fluorescence lifetime or the emission spectra from single perylene bisimide (PBI) dimers embedded in a polystyrene matrix. In these traces three distinct intensity levels can be distinguished, which reflect the photo-induced radicalisation of one of the perylene subunits. Differences in the energy transfer rate between the neut...

The effect of the geometrical parameter of blades on heat transfer co-efficient were experimentally studied for agitated vessels using coal slurry in coal gasification. The intensity of hear transfer during mixing of fluids depends on the type of the stirrer, the design of the vessel and conditions of the process. The type and size of the stirrer, as well as its location in the vessel, also aff...

background: embryo transfer (et) has traditionally been performed two days after oocyte retrieval. delaying transfer from day two to day three or four would allow for further development of the embryo might therefore optimize the selection of viable and best quality embryos for transfer and may be closer to the physiological time of the entry into the uterus than transfer on day two and might h...

This research deals with heat and mass transfer in biscuit industrial baking ovens. In these ovens, heat reaches biscuits indirectly by radiation, convection and conduction. The method for numerical solution is that we first provide the related equations, then they are discretized by finite difference method (FDM), and finally, after encoding and writing a program for the computer, we run it. T...
