The actual magnetic induction waveform of cores in electrical machines is not sinusoidal i.e. higher harmonics are always included. Thus the core loss in actual electrical machines is different from the core loss which is measured by the standard method, because the waveform of magnetic induction should be sinusoidal…

Fungal degradation of poly(L-lactide) (PLA) was studied using Tritirachium album ATCC 22563. In liquid culture using basal medium and PLA film, no film degradation was observed. However, by the addition of 0.1% gelatin, about 76% of the PLA film was degraded after 14 days of cultivation at 30°C. Furthermore, the cultu…

The mechanical and physical properties of fusible interlinings and fabrics depend on their constructional parameters, but fused panel properties depend on all of them. A new approach is presented for analysing the dependence of the constructional parameters of fabrics on the properties of fused panels. This study was…

The magnetoresistance (MR) and microstructures of half-metallic CrO2 nanoparticle systems were studied. Using field alignment, the needle-shaped CrO2 single domain particles were aligned in the same orientation. The MR of this structure showed a magnetic junction-like behavior with two well-separated peaks in the MR a…

The optimization of the ball milling parameters resulted in the synthesis with a milling duration equal to 10 hours of amorphous MgNi having an initial discharge capacity over 520 mAh/g. Further milling results in a partial crystallization of amorphous MgNi into nanocrystalline MgNi 2 and Mg2Ni, which decreases signif…

Examination of a wide range of experimental data relating to 'low-loss' dielectric materials reveals the little acknowledged fact that their loss at high frequencies (kHz to GHz) and low temperatures (typically 100 to 200 K) is weakly or very weakly dependent on frequency, what we call 'flat loss', and is likewise wea…

A new organic ionic crystal of 4-(dimethylamino)-1-ethylpyridinium iodide (DMAEPI) was synthesized for use in second-order nonlinear optics, and its crystal structure was found to belong to the orthorhombic space group Pmn2 1 . This crystal is considered to be a promising candidate for frequency conversion of diode la…

The opto-mechanical effect observed in amorphous chalcogenide films deposited onto clamped STM cantilevers 1 has been investigated. In this, bandgap light, incident on the chalcogenide film and linearly polarized either parallel or perpendicular to the cantilever axis, reversibly causes respectively either a contracti…

Magnetization experiments were performed on a series of single crystals of the bilayer manganites La2−2xSr1+2xMn2O7. The magnetic anisotropy constants were determined by fitting expressions based on the tetragonal anisotropy energy to the magnetization curves. It is shown that there is a significant dipolar contributi…

Abstract In this paper, we describe a new method to manufacture cholesteric colour filters. The cholesteric colour filter is made by a simple method, comprising one coating step and two UV exposure steps. The optical performance of the cholesteric colour filter and a reflective LCD with a cholesteric colour filter ins…

The role of cyclization in polycondensations is discussed for two different scenarios: thermodynamically-controlled polycondensation (TCPs) on the one hand and kinetically-controlled polycondensations (KCPs) on the other. The classical Carothers–Flory theory of step-growth polymerization does not include cyclization r…
