Stainless steel pipe with fine hole and long size has recently been needed for the flow line of pure gas and liquid, which is used in the field of precision machinery. Inner wall polishing of the capillary is very difficult by ordinary finishing methods. High speed slurry flow finishing method developed by authors has been proved to have excellent polishing performance, but it has been needed a...
Background and purpose: Giardia lamblia (G.lamblia) is one of flagellated protozoan pathogens. Giardiasis is the most common human parasite infection in the world, causing a lengthy course of diarrhea. The aim of the present study was to compare five different methods of DNA extraction from G.Lamblia cyst and determining the most efficient DNA extraction method. Materials and methods: This stu...
The utility of X-ray fluorescence spectrometry in the study of stable and degraded glass as well as coatings applied to ethnographic costume is discussed. South African Ndebele costume and ceremonial regalia were studied from the collection of the National Museum of African Art, Smithsonian Institution, as part of a larger condition survey of the entire beaded collection. The susceptibility of ...
Three established cell lines were examined for growth on a newly developed microcarrier which consists of glass beads. The cells were simultaneously examined for growth on comrnercially available microcarriers made from DEAE-dextran and from plastic. Cell yields on the glass microcarriers were comparable to the cell yields on the commercially available products. Cells grown on the glass microca...
The effects of (-)-isoproterenol covalently linked to glass beads on inotropic state, cyclic AMP concentration, and phosphorylase b to a conversion was studied in cat and guinea pig papillary muscles. Biochemical responses also were measured in mouse diaphragm sections. In cat papillary muscles under normal conditions and in guinea pig muscles partly depolarized with 22 mM K+ an increased inotr...
The eruption of the orange glass magma to form the deposits sampled at the Apollo 17 site is considered to have been a gas-rich, fire-fountain eruption. The deposit consists entirely of small 1-2 mm spherical beads of the orange glass created during fragmentation of the magma. The data on the gas phase components in the pre-eruption A17 orange glass magma are constrained by C-O-S system phase e...
We have performed extensive experimental and numerical studies of spontaneous percolation of small beads through an unconsolidated porous media made with large glass beads. In this paper, an experimental setup and a fast "discrete element method" algorithm are presented to deal with large numbers of particles during our interparticle percolation phenomenon studies. In all the experimental and n...
This article describes the development and the examination of surface coatings that suppress the adhesion between glass surfaces and polymer microspheres. Superparamagnetic doping allowed for exerting magnetic forces on the microbeads. The carboxyl functionalization of the polymer provided the means for coating the beads with polyethylene glycol (PEG) with different molecular weight. Under grav...
