Five subsequent multi-generational photocopies of 50 signature samples from different individuals which were produced by 75 black and white photocopiers were used for line quality assessments. Variations in line quality features in different photocopy generations, such as: smooth edges or ragged edges, broken or continuous stroke, fine tapering changes, and some identification details of features like pen lifts, retouching, and hesitation were carefully observed in sample photocopies, which were recorded according to the brand and model of photocopier machines, as well as their size and speed. The results of the study revealed that raggedness in line was often observed in third generation (G3) and higher generations, in samples produced by some low speed copiers (copying speed < 30 cpm) o...

The dietary treatment groups consisted of two levels of choline as TMA precursor viz; 3g/kg diet, 6g/kg diet and a control diet devoid of choline. The results revealed highly significant (P<0.0001) effect of choline on yolk weight and HU than the control. However the other egg quality traits i.,e egg weight, albumen weight, shell weight, albumen index, yolk index, shape index, shell thickness were not influenced. Serum cholesterol and triglycerides were significantly (P<0.0001) reduced in high choline group (6g/kg diet) followed by low choline group (3g/kg diet) and control. The liver enzymes (SGPT and SGOT) were significantly lower (P<0.0001) in both the supplemented ...

The surface morphologies, obtained using scanning electron microscopy, have been analysed using ImageJ to extract information about the dependence of petal thickness, petal density and linear porosity on the concentration at a given deposition and annealing temperatures. A detailed analysis shows how the synthesis parameters can be optimized to get a desired application specific nanostructure by taking an example of field emission properties. NiO NPs were prepared with three different precursor's concentrations out of which the sample prepared with lowest concentration was identified to show very good field emission property with high enhancement factor.
