BACKGROUND Skin graft is one of the commonly done procedures by plastic surgeons, dermato surgeons and general surgeons. Pain at the donor area is a common complaint by the patient. The skin graft donor site area is usually covered with petrolatum dressing dermatosurgeons. AIM This study was done to compare collagen dressing with petroleum gauze dressing in control of post-operative pain on s...

A novel frequency domain technique for image blocking artifact reduction is presented in this paper. For each block, its DC and AC coefficients are recalculated for artifact reduction. To achieve this, a closed form representation of the optimal correction of the DCT coefficients is produced by minimizing a novel enhanced form of the Mean Squared Difference of Slope (MSDS), for every frequency ...

CONTEXT Laboratory studies in cognitive psychology with relatively brief final recall intervals suggest that repeated retrieval in the form of tests may result in better retention of information compared with repeated study. OBJECTIVES Our study evaluates if repeated testing of material taught in a real-life educational setting (a didactic conference for paediatric and emergency medicine resi...

The understanding of the structural formula smectite minerals is basic to predicting their physicochemical properties, which depend on location cation substitutions within 2:1 layer. This implies knowing correct distribution and positions cations, allows assigning source layer charge tetrahedral or octahedral sheet, determining total number cations and, consequently, type smectite. However, som...

Any planar resistor (channel) close to a conducting layer left floating (gate) forms a capacitor C whose thermal voltage noise (kT/C noise) has a backgating effect on the sheet resistance of the channel that is a powerful source of 1/f resistance noise in planar resistors and, hence, in planar devices. This 1/f spectrum is created by the bias voltage VDS applied to the resistor, which is a dist...
