The anomalous-diffraction theory (ADT) of extinction of light by soft particles is shown to be determined by a statistical distribution of the geometrical paths of individual rays inside the particles. Light extinction depends on the mean and the mean-squared geometrical paths of the rays. Analytical formulas for optical efficiencies from a Gaussian distribution of the geometrical paths of rays...

The main aim of this study was determination of thermo- radio- and photostability ofperindopril tert-butyloamine (PER) therefore the efficiency and safety of the therapy could bemaintained.A chromatographic method (RP-HPLC) had been validated before use to determinePER loss. The evaluation of stability properties of PER in solid state under the influence ofisothermal condition, relative humidit...

Finger millet landraces viz., TZA-01 and TZM-01 were grown in glasshouses under two moisture regimes (fully irrigated and after drought) to investigate the effects of environmental stress on the growth, SPAD measurement, radiation use efficiency and yield of finger millet (Eleucine coracana). The drought treatment was imposed at 28 DAS beyond which no irrigation was applied to the droughted tre...

The differential global positioning system (DGPS) transmits a GPS enhancement signal using a top-loaded monopole antenna in the medium frequency range. The top-loaded antenna in the medium frequency band can attain a radiation efficiency on the order of 10%. The antenna ground plane characteristics affect the antenna radiation efficiency. To improve the radiation efficiency, it is necessary to ...

the present study was carried out to evaluate radiation absorption and use efficiency (rue) in replacement series intercropping of chickpea and sesame. the experiment included main factor a (planting methods) with two levels a1 (row planting) and a2 (mixed planting) and factor b (replacement planting pattern) consisting of five levels b1 (chickpea monoculture), b2 (75% chickpea+25% sesame), b3 ...

A novel circular polarized antenna structure capable of high radiation efficiency, and suitable for use in multilayer microwave circuits is presented. The antenna uses dual ring feed system to enhance radiation. Data is provided for a prototype antenna working at 10GHz.
