Involvement of attentional processes is generally evidenced by disruption of behavior in the presence of distracting stimuli. The medial prefrontal cortex (mPFC) seems to play a role in fine-tuning activity during attentional tasks. A novel titration variant of the 5-choice serial reaction time task (5-choice serial reaction time titration variant [5CTV]) that adjusts task difficulty based on s...

background split- thickness skin graft is one of the most common operations in plastic surgery. it is always painful and patient discomfort from donor site often is more significant than recipient site. there is not still a standard method for treatment of the donor site. the purpose of this study was to determine the best method of dressing the donor site among three different methods with res...

We prove that the multigrid method works with optimal computational order even when the multiple meshes are not nested. When a coarse mesh is not a submesh of the finer one, the coarse-level correction usually does not have the a(-, •) projection property and does amplify the iterative error in some components. Nevertheless, the low-frequency components of the error can still be caught by the c...

Analysis of temperature and the cool ing rates during the weld ing process is essential to determine the deformation and residual stresses, and hence, the load-carrying capacity of the weldments. Numerical methods wi th nonl inear tenqperature-dependent mechanical properties with latent heat effects have been developed in recent years. The accuracy and computational efficiency of these methods ...

The distortion product otoacoustic emission (DPOAE) fine structure is revealed, when measuring DPOAE with a very fine frequency resolution. It is characterized by consistent maxima and minima with notches of up to 20 dB depth. The fine structure is known also from absolute hearing thresholds, and has recently been demonstrated to exist in low level equal-loudness contours. The character of the ...

A prospective study was undertaken on suspected lymph node TB (LNTB) patients, to evaluate the diagnostic utility of mycobacterial culture of fine needle aspirate (FNA), in comparison with the cytological examination and acid fast staining. Eighty percent of 157 aspirates studied were positive by cytological examination; 18% by ZN smear and 45% were positive by culture. Twelve aspirates which w...
