One of the many applications of micro computed tomography (microCT) is to accurately visualize and quantify cancellous bone microstructure. However, microCT based assessment of bone mineral density has yet to be thoroughly investigated. Specifically, the effects of varying imaging parameters, such as tube voltage (kVp), current (microA), integration time (ms), object to X-ray source distance (m...

Previous finite difference codes developed for this consortium were unstable at rough, sharp liquid-solid interfaces. In this paper we present results from a method developed by Nicoletis (1981) and Bhasavanija (1983) which is stable at rough, sharp liquid-solid interfaces. The method gives acceptable accuracy for the vertically homogeneous case when compared with discrete wavenumber results. E...

Understanding the function of Trichoderma species in the control of Phytophthora drechsleri in pistachio orchards is very important.  In this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of Trichoderma harzianum, T. crassum, T. koningii, T.aureoviride, T. asperellum, T. brevicompactum, T.longibrachiatum and T. virens were investigated on ...

Immobilization of particulates, especially biomolecules and cells, onto surfaces is critical for imaging with the atomic force microscope (AFM). In this paper, gelatin coated mica surfaces are shown to be suitable for immobilizing and imaging both gram positive, Staphylococcus aureus, and gram negative, Escherichia coli, bacteria in both air and liquid environments. Gelatin coated surfaces are ...

The requirements for dental material include not toxic, not irritant, no carcinogenic potential, nor cause an allergic response with the use in oral cavity. The cyanoacrylate restoration material has certain substance that can be toxic. Because of the ratio amount of powder and liquid is not known, it can lead the restoration more toxic. The purpose of this study was to know the cytotoxicity of...

Evaporation of volatile liquids from nanoporous media with bicontinuous morphology and pore diameters of a few 10 nm is an ubiquitous process. For example, such drying processes occur during syntheses of nanoporous materials by sol-gel chemistry or by spinodal decomposition in the presence of solvents as well as during solution impregnation of nanoporous hosts with functional guests. It is comm...

Pathogenic Naegleria fowleri, Acanthamoeba castellanii, and Acanthamoeba polyphaga, are distributed worldwide. They are causative agents of primary amoebic meningoencephalitis or acanthamoebic keratitis in humans, respectively. Trophozoites encyst in unfavorable environments, such as exhausted food supply and desiccation. Until recently, the method of N. fowleri encystation used solid non-nutri...

This study assesses the effect of the enrichment medium used on the isolation of Salmonella from the duodenal content of naturally infected slaughter pigs. At six slaughterhouses, the duodenum was collected from 458 randomly chosen pigs and examined in the laboratory. Three semi-solid enrichment media (modified semi-solid Rappaport-Vassiliadis medium [MSRV], diagnostic semi-solid Salmonella med...

Filtration media are required to have suitable pore size, pore size distribution, pore volume, pore surface area and permeability for performing satisfactorily in applications. It is difficult to encounter all the desired properties in a filtration medium. In this investigation, we have characterized filtration media by flow porometry, used these pre-characterized filtration media to design com...
