Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

NOTE: *These temperature ranges will apply to the majority of media for which the material is potentially recommended. With some media however, the service temperature range may be significantly different. ALWAYS TEST UNDER ACTUAL SERVICE CONDITIONS. Nitrile (General Service) -34°C to 121°C (-30°F to 250°F)* Nitrile (Low Temperature) -55°C to 107°C (-65°F to 225°F)* Hydrogenated Nitrile -32°C t...

ABSTRACT- Aerobic biodegradation is an environmental-friendly biological method that allows micro organisms to remove persistent organic pollutants. Aroclor1254 is a mixed compound containing polychlorinated biphenyls (PCBs) along with persistent organic materials. There is no estimate of Aroclor1254 usage and its release into the environment in Iran. A transformer manufacturing plant in Shiraz...

OBJECTIVE Tenascin-C, an extracellular matrix glycoprotein, is thought to play an important role in neointimal hyperplasia of artery bypass grafts. In this study, the direct contribution of tenascin-C to neointimal hyperplasia of free artery grafts and the origin of tenascin-C-producing cells were examined using tenascin-C transgenic mice. METHODS AND RESULTS Abdominal aorta-to-carotid artery...

this experiment was conducted to determine the potential synergistic relationship between enterococcus faecium and fructans with different average degree of polymerization (dpav) including oligofructose (of, dpav 4), standard-inulin (st-inulin, dpav 10), synergy1-inulin (syn1-inulin, dpav 15) and high-polymer inulin (hp-inulin, dpav 25). a sterilized minimal mrs broth media was prepared by omis...

Metal-catalyzed cross-coupling reactions have developed into a standard component of the synthetic chemist’s toolbox [1–4]. These reactions date to thework ofUllmann and Goldberg in the early 1900s on copper-promoted C–C and C–heteroatom bond formations. Copper remained the catalyst of choice for these reactions until the pioneeringwork ofHeck, Suzuki, Stille, Negishi, and others on palladium-c...

in this paper, analysis and simulation of media gateway controller (megaco) based cops (common open policy server) which is a protocol defined in ietf (internet engineering task force) to transport configuration requests and deliver the policies is presented. for this scenario, three queuing models include m/m/1, m/m/c and m/d/c were applied . then, some of the key performance benchmarks look l...

The present study is concerned with the production of cephalosporin C by Cephalosporium acremonium C-10. Two culture media were tested for the production of antibiotic. Among these culture media M1 containing sucrose, ammonium acetate, cornstarch, sugar cane molasses, soybean meal, calcium carbonate, calcium sulphate and methyl oleate gave optimum production of cephalosporin C. The cultural con...

the selection of a growing medium is one of the most important decisions in the culture of hydroponic crops. in order to select a suitable medium for hydroponic cucumber (cucumis sativus l. cv. negin), an experiment was carried out on growing media containing different particle sizes of perlite and organic substrates in a run-to-waste system in a greenhouse experiment. the growing media tested ...

the distribution of gallium(b) and indium (b) between hydrochloric or sulphuric acid solution with sec-nonylphenoxy acetic acid(ca-100) in kerosene has been investigated under various conditions. ca-100 is a new organocarboxylic extractant, which has been shown to be efficient for gallium(b) and indium(b) whereas germanium(c), which was not extracted. the extraction system is studied as a funct...
