Modification of a digital image by adding or removing some of its elements using a wide variety of image processing tools results in image forgery. As a result authentication of originality of a digital image is becoming a challenging task. Copy-paste forgery is one of the forgeries belonging to context based forgery. Copy-Paste Forgery Detection (CPFD) aims at finding regions that have been co...

Abstract In this work, a series of tellurite glass frits has been prepared and used as the silver paste in Ag electrode solar cells. The softening temperature have characterized by differential scanning calorimeter. G3 lowest temperature, corresponding composition is 42wt.%TeO2-53wt.% PbO-1wt.%B2O3-4wt.%Bi2O3. surface cross-sectional microstructures cells electron microscope. with lower showed ...

INTRODUCTION Enamel demineralization is a problem in orthodontics. Fluoride is partially effective in addressing this problem, but additional treatment options are needed. The objective of this prospective randomized controlled trial was to determine the effectiveness of a new product, MI Paste Plus (GC America, Alsip, Ill), in the prevention or reduction of white spot lesions in orthodontic pa...

The freezing of water in Portland cement paste was investigated using a.c. impedance spectroscopy techniques. Length change and impedance measurements on cooling and warming were obtained simultaneously using a specially designed coupling technique. A new descriptor of frost resistance is described in terms of the high frequency arc depression angle in the impedance plane. Curves of the depress...

Thermal pastes play an important role in transmitting heat generated by an integrated circuit chip from its back side to a cooling cap or heat sink which transfers the heat to the environment. Most thermal pastes are formulations of solid, thermally conducting particles in a liquid matrix loaded to very high solids content. The mixing process for such pastes is complex but important, since it d...

Traditional soybean paste from Shandong Liangshan and Tianyuan Jiangyuan commercial soybean paste were chosen for analysis and comparison of their bacterial and fungal dynamics using denaturing gel gradient electrophoresis and 16S rRNA gene clone libraries. The bacterial diversity results showed that more than 20 types of bacteria were present in traditional Shandong soybean paste during its fe...

Completion of root development takes around 3 years after eruption of permanent teeth. Any pulpal injury in this period can lead to necrosis of pulp. Pulp necrosis of immature permanent teeth may impair root development and apical closure of root canals. Management of immature non vital teeth is very challenging for a clinician because teeth may have wide open apex and thin root canal walls tha...

The production of the soluble cytochrome oxidase/nitrite reductase in the bacterium Pseudomonas aeruginosa is favoured by anaerobic conditions and the presence of KNO3(20g/l) in the culture medium. Of three methods commonly used for the disruption of bacterial suspensions (ultrasonication, liquid-shear homogenization and glass-bead grinding), sonication proved the most efficient in releasing th...
