Abstract A new family of hybrid/mixed finite elements optimized for numerical stability is introduced. It comprises a linear hexahedral and quadratic tetrahedral elements. The element formulation derived from consistent linearization well-known three-field functional related to Simo–Taylor–Pister () For the we derive (static reduced) discontinuous hybrid elements, as well continuous mixed with ...

The aim of this study was to evaluate cytotoxicity of direct pulp capping materials such as Dycal, Life, ProRoot MTA, and Super-Bond C&B on L929 fibroblasts. Freshly mixed or set materials were prepared and eluted by incubation with cell culture medium for working time period (fresh) or for 6 hours (set). The cells were exposed to media containing elutes for 24 hours, after which the cell survi...

In the 1980s and 1990s, the development of oxygen ion conductors for solid electrolytes, as well as mixed oxygen–electron conductors as electrodes for solid oxide fuel cells, brought scientists to envision a possibility of mixed-conducting oxygenpermeable ceramic membranes. Today this field is well established, and ceramic membranes are close to implementation in processes for oxygen extraction...

Normal Rana pipiens gastrulae show more incorporation of isotopically-labelled galactose and glucosamine into TCA-insoluble materials than blastulae. Interspecific hybrid embryos which undergo developmental arrest at the onset of gastrulation often synthesize reduced amounts of galactose- and glucosamine-labelled materials. These materials are high-molecular weight, but not collagen. After pron...

--------------------------------------------------------ABSTRACT------------------------------------------------------------It is revealed that microbes survive on all classes of textiles materials comfortably and used them as source of nutrient. The outcome of this on the textile materials, environments and humans is devastating. Several attempt by researchers to minimize the effects using ant...

introduction: candida albicans (ca) is by far the most common yeast of oral infections, including endodontic infections. the aim of this study was to evaluate and compare the antifungal effect of white-colored mineral trioxide aggregate (wmta) and portland cement (pc) using a tube-dilution test. materials and methods: wmta and pc were tested freshly mixed and after 24 h. the experiment was perf...

At many circumstances, in heat exchange processes several exchangers were used with different cost laws due to their pressure ratings, materials of construction and exchange3r types. In such circumstances traditional methods of pinch technology can not be led to minimum total annual cost may cause some other disadvantages like more complexity or higher maintenance. In this research work a n...
