Master moulds are used to cast copper anode moulds. These iron moulds are made of grey or nodular cast irons. According to desirable properties of ductile irons, it was expected that ductile cast iron ...

High density polyethylene (HDPE) films were produced using cast film extrusion process with different draw ratios, ranging from 16.9 to 148.8. Morphology, crystallinty and orientation state of crystalline and amorphous phases of the cast films were investigated using scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and polarized Fourier transform infrared spectroscopy...

In a natural environment, cast shadows abound. Objects cast shadows both upon themselves and upon background surfaces. Previous research on the perception of 3-D shape from cast shadows has only examined the informativeness of shadows cast upon flat background surfaces. In outdoor environments, however, background surfaces often possess significant curvature (large rocks, trees, hills, etc.), a...

Color cast defect detection of video image is challenging and of great importance in the field of video quality evaluation, and one of the difficulties therein is how to distinguish a dominant color (caused by a predominant color, such as an image in which blue sky is a basic tone) from an inherent cast (image presenting a cast due to imaging device failure or taken in a special environment, su...

BACKGROUND Calpain is activated following myocardial infarction and ablation of calpastatin (CAST), an endogenous inhibitor of calpains, promotes left ventricular remodeling after myocardial infarction (MI). The present study aimed to investigate the effect of transgenic over-expression of CAST on the post-infarction myocardial remodeling process. METHOD We established transgenic mice (TG) ub...

Calpastatin, an important protein used to regulate meat quality traits in animals, is encoded by the CAST gene. The aim of the present study was to clone the cDNA sequence of the CAST gene and detect the expression of CAST in the tissues of Cyprinus carpio. The cDNA of the C. carpio CAST gene, amplified using rapid amplification of cDNA ends PCR, is 2834 bp in length (accession No. JX275386), c...

BACKGROUND The scaphoid fractures account for 50%-80% of all carpal bone fractures in young individuals. Non-union of the fracture occurs in approximately 5%-10% of undisplaced scaphoid fractures. Current management varies significantly among different places and surgeons. OBJECTIVES The purpose of this review is to investigate the evidence of the effectiveness and safety of various treatment...

abstract   background: fractures of the tibia are important for their commonness and controversy in their management. both conservative and surgical techniques have been introduced in an effort to speed time to :::::union::::: while minimizing the occurrence of complications. standard treatment for low-energy tibial shaft fractures includes closed reduction and cast immobilization. the purpose ...

some manufacturers claim to have produced new irreversible hydro-colloids that are able to maintain their dimensional stability during storage. the present study evaluated the effect of storage time on dimensional stability of three alginates: hydrogum 5, tropicalgin and alginoplast.in this experimental in-vitro trial, a total of 90 alginate impressions were made from a dentoform model using hy...
