The thick films of Tungsten Oxide (WO3) were prepared by screen-printing technique. Gas-sensing performance of these films was tested for various gases. The pure films showed response to Hydrogen Sulphide, Ethanol, Oxygen, and Cigar smoke. The pure WO3 thick films were surface modified by dipping them into an aqueous solution of CrO3 for different intervals of time. Surface modification improve...

A system of models has been developed to study transient flow during continuous casting and applied to simulate an event of multiple stopper-rod movements. It includes four sub-models to incorporate different aspects in this transient event. A three-dimensional (3-D) porous-flow model of the nozzle wall calculates the rate argon gas flow into the liquid steel, and the initial mean bubble size i...

In the western Sydney Basin, the Lapstone Structural Complex is a major north-trending association of monoclines and faults that forms the frontal ridge of the Blue Mountains Plateau. At Kurrajong Heights, the Lapstone Structural Complex is dominated by an eastfacing monocline with a gently dipping central limb containing several different homoclinal segments. At the Hawkesbury Lookout section,...

demographic toxicology is a common method for an investigation of the sub lethal effects of pesticides on natural enemies. the present study was conducted to evaluate the side effects of the extracts of calotropis procera (willd.) r. br. (asclepiadaceae), teucrium polium l. (labiatae), fumaria parviflora lam. (fumariaceae) and thymus vulgaris l. (labiatae) in comparison with three pesticides: h...

Hot solder dipping is an accepted method to mitigate whisker growth on electronic components plated with pure tin. To provide the best protection from tin whiskers, the solder coating needs to be up to the package body. The conventional wisdom for solder dipping maintains that dipping up to the package body can cause component damage. If the specific construction differences of ceramic and plas...

In this paper, optimized perfect reconstruction octave-band two-stage and three-stage tree-structured lter banks and optimized uniform four-channel and eight-channel lter banks are compared for hybrid video coding. The lter co-eecients are optimized at each stage for subband coding gain for nonuniform lter banks. Six types of frequency partitionings are presented to compare the eecient utilizat...

BACKGROUND & OBJECTIVES Angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) have been used to normalize the blood pressure and the dipping pattern in patients with type 1 diabetes mellitus (T1DM) and nephropathy. However, there are no data on the effect of the dual blockade on the dipping pattern in these subjects. We therefore, carried out this study to eva...
