The solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It is a non-linear transient phenomenon, posing a challenge in terms of modelling and analysis. During the solidification of a casting in a mould, the heat-transfer between the casting and the mould plays a vital role. This paper attempts to study ...

A stumbling point for many learning to fly fish is being able to fly cast well enough to ‘present’ a fly to a feeding fish. Even among more skilled fly fishers, learning to fly cast better is often a bottleneck towards advancement in the sport. Fly casting instruction today relies on the visual inspection of the fly casting stroke and the resulting ‘loop’ of fly line. These qualitative visual c...

This paper describes a method to generate Delaunay tetrahedral meshes directly from regular volume data by vertex insertion driven by an error criterion. By adapting the mesh to the input data, the method produces meshes suitable for fast and precise volume ray-casting. A partitioning method that splits the mesh into homogeneous sub-meshes is also presented. Such mesh segmentation strategy turn...

There is a growing need for custom visualization applications to deal with the rising amounts of volume data to be analyzed in fields like medicine, seismology, and meteorology. Visual programming techniques have been used in visualization and other fields to analyze and visualize data in an intuitive manner. However, this additional step of abstraction often results in a performance penalty du...

The dimensionless Niyama criterion was used to predict the formation of microporosity in nickel-based superalloy casting, which extended the model application from a simple plate casting to complex thin-wall superalloy casting. The physical characteristics of the superalloy were calculated by JMatPro software. The relation between the volume percentage of microporosity and the dimensionless Niy...

conclusions employing the lpe as a new approach, gives novel concept of probiotic-products in food and medical marketing. results results showed that, lpe had more antipathogenic effects, antioxidant activity, and stability during storage-time when compared to fresh probiotic-extract. objectives in this study extract of cultured probiotics without cells was evaluated for its antimicrobial effec...

the aim of this study was to determine the effect of low levels of glutathione on post-thawed buck sperm quality. in this experiment, different concentrations of glutathione [0 (lg-0), 0.5 (lg-0.5), 1 (lg-1), 1.5 (lg-1.5), and 2 (lg-2) mm] were added in a soybean lecithin-based extender. a total of 16 ejaculates from four bucks were collected and pooled. each pooled sample was divided into five...

Waste tires, rubbers, plastic and steel materials, normally produced in every society, enter the environment and cause serious problems. These problems may, to some extent, be reduced by finding applications for them in engineering, for example, they can be used for geotechnical applications as backfill material and solving problems with low shear strength soils. Such materials may be subjected...

background black pepper (piper nigrum) is one of the well-known spices extensively used worldwide especially in india, and southeast asia. the presence of alkaloids in the pepper, namely, piperine and its three stereoisomers, isopiperine, chavicine and isochavicine are well noticed. objectives the current study evaluated the effect of lyophilization and oven drying on the stability and decompos...
