Review of applications of partial differential equations for image enhancement
Image restoration and enhancement are important parts of digital image processing, belonging to the early visual image processing problems. Image pre-processing is the necessary preliminary work of image analysis, such as filtering to reduce image noise and to enhance the image edges. The image enhancement technique plays an important role in improving image quality and is good for image post-processing e.g. image...

Effect of gastric symptoms, age and gender on quality of life
Digestive symptoms are the most common and frequent symptoms being reported. It is difficult to measure their effects on quality of life, as they varied by age and gender. Therefore, our aim was to determine the effect of gastric symptoms on quality of life and to explore their relationship with age and gender. A secondary analysis of an original pragmatic randomized trial with repeated measurements was conducted in...

Antioxidant activity of bamboo-leaf extracts from the species Dendrocalamopsis oldhami
The antioxidant enzymatic activities of Dendrocalamopsis oldhami bamboo-leaf extracts (BLE) in cholesterol-fed rats and an index of lipid peroxidation were determined. In the BLE groups, compared with the control group, significant decrease was observed in superoxide dismutase (SOD) activity in the livers and kidneys, catalase (CAT) activity in the kidneys, and glutathione peroxidase (GSH-Px) activity in...

Experimental investigation on centrifugal casting of 5500 alloy: A Taguchi approach
Design of experiments has been used, to study the influence of process parameters on the mechanical properties during centrifugal casting of aluminum alloy (5500). Taguchi method of design of experiments was employed to optimize the process parameters and to increase the mechanical properties such as UTS, elongation, BHN. The investigation has indicated that increase in pouring temperature reduces mechanical properties...

Effects of fluorine incorporation on the microstructure and optical properties of ZnO thin films synthesized by Sol-gel technique
Fluorine doped Zinc oxide (ZnO) [FZO] transparent conducting thin films were deposited by sol-gel spin coating method. Zinc acetate and amonium fluoride were used as precursor solution materials. Microstructural, morphologycal, and optical properties of the films were investigated as a function of flourine (F) doping ranging from 0 to 3.5% mole. From x-ray diffraction (XRD) patterns the films...
