various basidiomycetes and deuteromycetes, grown in liquid and solid culture media, were compared for their laccase-producing ability and for the inducing effect of soil and agricultural residues on laccase production. laccase activity in extracts of all solid media was higher than that of the liquid media. in liquid cultures, fungal laccase activity in ex-tracts of pea (pisum sativum) straw-tr...
the dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. with the help of displacements and stresses green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
in vitro propagation of plant has played a very important role in rapidmultiplication of cultivars with desirable traits and production of healthy and disease-free plants. in the present investigation, the objectives were to optimize the micropropagation of rose hybrid ‘black baccarat’ cultivar. in proliferation step, the nodal segments (1.5 cm) was cultured on both liquid and solid media (ms, ...
Experiments were carried out in order to micropropagate sugarcane cultivars through shoot tip and auxilliary bud culture. Rinsing of four cultivars of sugarcane, namely CP-48-103, CP-57-614, CP-69-1062, and NCO-310 in 75% alcohol for 60 seconds and their subsequent disinfection with sodium and calcium hypochloride (1.5% active material) for 15 minutes decreased a significant amount of infection...

How can the large power needs of future electric ships for propulsion, radar, and weapons systems be met given the prohibitive size and weight of the required number of standard 60 Hz AC generators and transformers? A solution may lie in a rugged, efficient, and compact solid-state, 10-20 kV Medium Voltage DC (MVDC) circuit breaker (Figure 1). In this paper, Diversified Technologies, Inc. will ...
