We study the resonant wavelength of nanograting structures covered by a dielectric medium. We find that the resonant wavelength oscillates as the thickness of the thin dielectric layer increases due to the cavity formed by the dielectric layer. The amplitude of this oscillation in the resonant wavelength is small when the minimum reflection occurs in the nanograting structure. For a plasmonic s...

The effect of the magnetic field dependent (MFD) viscosity on the thermal convection in a ferromagnetic fluid in the presence of a uniform vertical magnetic field is considered for a fluid layer in a porous medium, heated from below. For a ferromagnetic fluid layer between two free boundaries an exact solution is obtained, using a linear stability analysis. For the case of stationary convection...

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...

Procedures for forming and regenerating protoplasts of four Frankia strains are described. Cells obtained from growth medium containing 0.1% glycine were digested with lysozyme (250 mug/ml) in a medium containing 0.5 M sucrose, 5.0 mM CaCl(2), and 5.0 mM MgCl(2). Protoplasts were formed during 15 to 120 min of digestion at 25 degrees C. Optimum conditions for protoplast regeneration involved pl...

This work examines reflection of a light from a semiinfinite medium which is modified with an ordered monolayer of spherical nanoparticles placed on or under its surface. We derive analytical expressions for the electric fields within and outside such structures and verify them with help of strict numerical simulations. We show that nanoparticles layer acts as an imaginary zero-thickness surfac...

Agrobacterium tumefaciens C58 grown on acidic medium containing glucose and solidified with bacteriological agar expressed a virB::lacZ fusion. No expression of this fusion was observed on a similar medium which was solidified with purified agarose. The fraction from bacteriological agar which was responsible for vir gene induction was extracted with methanol and partially purified by preparati...

SMEs (Small and Medium Enterprise) have become the importantly compositive part of Chinese Nation Economy. And management and innovation of SME have become one of the key problems of the process of growing up and development of SME. In this paper, a system framework of SME innovation system is introduced, and the system framework includes core layer, expression layer, enabling layer and infrast...

The primary culture of neuronal cells plays an important role in neuroscience. There has long been a need for methods enabling the long-term culture of primary neurons at low density, in defined serum-free medium. However, the lower the cell density, the more difficult it is to maintain the cells in culture. Therefore, we aimed to develop a method for long-term culture of neurons at low density...

In order to realize real-time communication over Ethernet or fast Ethernet, one must be able to bound the medium access time within an acceptable limit. The multiple access nature of an Ethernet makes it impossible to guarantee a deterministic medium access time (hence packet delivery deadlines) to individual stations. However, one can bound the medium access time statistically by limiting the ...

In this work the mechanism of (3-aminopropyl)triethoxysilane (APTES) interaction with silicon surfaces is investigated at the molecular level. We studied the influence of experimental parameters such as time, temperature, and concentration on the quality of the APTES layer in terms of chemical properties, morphology, and stability in aqueous medium. This was achieved using a highly sensitive IR...
