The kinetics of solid–solid interfaces controls in part the course of heterogeneous reactions in the solid state, in particular in miniaturized systems. In this paper, the essential situations of interface kinetics in solids are defined, and the basic formal considerations are summarized. In addition to the role interfaces play as resistances for transport across them, they offer high diffusivi...

Dormancy in non-sporulating bacteria is an interesting and underexplored phenomenon with significant medical implications. In particular, latent tuberculosis may result from the maintenance of Mycobacterium tuberculosis bacilli in non-replicating states in infected individuals. Uniquely, growth of M. tuberculosis in aerobic conditions in potassium-deficient media resulted in the generation of b...

Coccidioides immitis undergoes a completely different type of growth in vivo from that in vitro. The parasitic form, or spherule, appears in animal tissue as a non-budding, spherical structure 20 to 80 ,u in diameter with a thick, refractile, double wall, and is filled witlh numerous small endospores 2 to 5 ,u in diameter. The saprophytic form appears in laboratory media as mycelium with branch...

Tissue culture is an attractive alternative for plant propagation. Micropropagation is a technique to ensure a constant and uniform source of ornamental plants. Matthiola incana is an important ornamental species mainly cultivate by seed. Matthiola incana seeds were germinated on solid MS medium without plant growth regulators. Shoot proliferation and root formation are possible using kinetin (...

For centuries, Damask rose has been one of the most popular species of the rose family. Damask rose can be propagated using vegetative methods such as micropropagation. In this research, the use of temporary immersion system was reported for the first time for Damask rose micropropagation. For this reason, a traditional temporary immersion system was designed to facilitate its micropropagation....

an efficient and cost effective protocol for in vitro propagation of pineapple (ananas comosus var. queen) has been developed. in the proliferation stage, agar based murashige and skoog (ms) media was supplemented with 3.0 mg/l benzyleaminopurine (bap), 0.5 mg/l indole acetic acid (iaa) and 50 mg/l adenine sulphate as rbc design experiment. two approaches were taken to reduce the chemical cost ...

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...

Fischer, 0.: Enhancement of Propagation of Mycoplasma hyopneumoniae by Culture in a Biphasic Medium. Acta vet. Bmo, 1995,64:243-247. Mycoplasma hyopneumoniae (strain J) was propagated in a liquid and a biphasic media. The solid phase of the biphasic medium was obtained by the addition of 1.9% or 0.19% of agar to the liquid medium. Compared with the liquid medium, a more rapid propagation of myc...
