Early work of E. Yablonovitch and his co-workers and also by S. John stimulated tremendously the interest of many researchers, who suggested that diffraction by periodic structures might lead to a photonic insulator in which propagation of light is forbidden in a certain range of frequencies. These photonic insulators are known as Photonic Band Gap (PBG) structures have a large number of applications in the field of photonics and integrated optics. Many applications in optics and microwaves are emerging by using the concept of PBG materials and structures.

The high hardness and melting point with excellent abrasive and corrosion resistance properties makes it most suitable for cutting tool industries. In order to increase the tool life efforts are being made to synthesize nano size WC powders through different techniques. In the present work WC nano particles were synthesize at comparative low temperature by thermo chemical route, and by mechanical synthesis route direct from the Wolframite ore. The synthesized nano WC powders were embedded in cobalt matrix and sintered. Cutting tool based on nano structured WC-Co particles will bring a revolutionary change in the development of cutting tool and also affect the cost of many other products related to the development of tool materials. The tool life is directly related to the size and distribution of WC particles in Co matrix. The reduced size of WC particles will lead more uniform distribution of it in Co matrix, which ultimately will lead to have more life time of cutting tool as compared to conventional material. ····· 1036125855

The thermal conductivity is a measurement of the material`s ability to conduct heat. The Transient Hot Wire method is a suitable method to measure the thermal conductivity due to its very cheap cost of construction, accuracy and because it is a fast method of measurement. The implementation requires accurate temperature sensing, automatic control, data acquisition and data analysis. The basic procedure consists of measuring the temporal temperature rise in a thermoresistance (thin wire) immersed in the solution by applying an electrical current in the wire. Therefore, the wire works as a heat source and a temperature sensor. The time of measurement is very short and therefore the convection effect could be minimized. Then, the heat transfer to the infinite medium is due only to the conduction transfer effect. The thermal conductivity can be determined from the slope of the curve DeltaT versus ln(t) due to the linear relation between DeltaT and ln(t). ····· 1036125772

A diode laser with wavelength of 671 nm and output power of 100 mW and a photomultiplier tube were used to find the relation between drug concentration and the scattered intensities of the laser beam at angles of 45o, 90o and 135o with respect to the direction of incidence for the samples: Benzylpenicillin sodium (BS), metronidazole and actrapid HM (insulin human) (IH). The results showed that the relation between the angular scattered intensity and sample concentration is linear. The study proved that this setup was very sensitive to detect the change in the scattered laser intensities for any small change in sample concentration from its standard concentration. From the features mentioned above it was clear that this setup was very efficient in discovering any manipulation in the drug concentration. ····· 1036125616

It was so named in relation to the concept of quantum mechanics established by Bohr, Heisenberg, Schrödinger and numerous others.

Comprehensive and up-to-date theme of PF inherits from nonuniformity, would substantially assist anyone to gain a thorough knowledge including its mountingly consequential roles in linear wave dynamics. Nonlinear Gardner solitons exist around the critical value.

····· lezzter Preis 44.10€ ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray New branches of spin waves spectra in non-ferromagnetic conductors and two-dimensional electron gas were predicted. The resonance (local, quasilocal and magnetoimpurity) electron states on impurity atoms were taken into account. Near frequencies of electron resonance transitions between spin split resonance levels and Landau levels there exist weakly damped spin magnetization oscillations called magnetoimpurity spin waves. A physical cause for existence of these waves is localization of electrons on impurity atoms stimulated by a magnetic field. The localization attenuates dissipation processes and leads to a possibility of propagation of new spin waves which are absent in pure samples. A spectrum and damping decrement of these waves were determined. New resonance features in an energy spectrum of inelastic neutron magnetic scattering on spin waves in conductors and two-dimensional electron gas with resonance states of electrons in a magnetic field were discovered. ····· 1036125245

Those miniaturized devices, integrating one or more laboratory functions, have aroused great interest among several research areas as physics, chemistry, biology and bioengineering. The high hydrodynamic resistance the liquid experiences in a lab-on-a-chip imposes the device to be connected to pumping systems thousands of times bigger than the chip itself, thereby erasing many advantages of a millimeter-sized device. In this respect, superhydrophobic surfaces have demonstrated to be an effective tool to reduce the fluid/solid friction. This thesis is part of the wider project of setting up an innovative technique to investigate the fluid-solid slippage on such surfaces by means of optical tweezers. This work reports the steps performed along the way towards this main goal and it consists of a collection of several researches involving different scientific fields as optics, microscopy, surface science, microhydrodynamics, microfluidics and microfabrication. ····· 1036125240

The self-ordered bistable fronts in the essentially dissipative systems of the reaction-diffusion type, that are formulated by parabolic partial differential equations, are investigated in this study. The objective of the research is to investigate new possibilities of controlling the directed net motion of the self-ordered bistable fronts by the deterministic and stochastic zero-mean ac forces using mathematical modeling and analytic tools. In order to achieve the objective mathematical and numerical models were applied, computer software was created and new possibilities of controlling the directed net motion of bistable fronts by use of the zero-average periodic, quasi-periodic and bounded noise fields were investigated. ····· 1036125152

The dispersion relation is analysed both analytically and numerically. From the analysis of the solutions of the dispersion relations, it is found that all existing kinds of MHD waves have in the case of ultrarelativistic plasma definitely different phase velocities as compared to the one from standard theory of linear MHD waves in cold colissionless plasma . Where as, the condition for fire-house instability remains the same. On the other hand, from the numerical analysis, polar plots of the phase velocities of the different wave modes for different cases are also drawn. Beside this, we came across that the extension of the 2D problems to 3D, results in the occurrence of an additional Alfven wave modes in 3D problems. ····· 1036125118

Solutions of the nonlinear equations of oscillator in the form of final Volterra series in the time and frequency domains, corresponding to anharmonicity, nonlinear attenuation and nonlinear excitation are received. Nonlinear effects will lead not to frequency mixing resulting in generation of oscillations with combinational frequencies, but to time mixing, i.e. to generation of signals at combinational instants of time. Attention is paid both to the duality of mediums under consideration and classical nonlinear circuits and to the opportunity of realization of signals real time processing in those mediums. ····· 1036124902
