Context. Reflected light from giant planets is polarized by scattering, offering the possibility of investigating atmospheric properties with polarimetry. Polarimetric measurements are available for the atmospheres of solar system planets, and instruments are being developed to detect and study the polarimetric properties of extrasolar planets. Aims. We investigate the intensity and polarizatio...

background: onchocerciasis is endemic in the imo river basin, nigeria. this study was aimed at assess­ing the prevalence and intensity of microfilaria of onchocerca volvulus in the area. methods: a cross-sectional study was carried out in the okigwe local government area, imo state, nige­ria. two skin snips (one from the waist and another from the shoulder) were taken from 1024 individu­als exa...

Aminochromes of adrenaline and noradrenaline show resonance Raman scattering at 1480 and 1430 cm(-1) respectively, with Ar(+) excitation. Scattering intensity is a linear function of concentration. Detection limits are 1 x 10(-6)M. Both catecholamines can be determined in a single measurement.

In the early deployment of electric toll collecting (ETC) system, multipath interference has caused the malfunction of the system. Therefore, radio absorbers are installed in the toll gate to suppress the scattering. This paper presents a novel radio propagation measurement system to identify the individual scattering object and the power intensity of the ETC gate in real time.

The effect of a weak source of noise on the chaotic scattering is relevant to situations of physical interest. We investigate how a weak source of additive uncorrelated Gaussian noise affects both the dynamics and the topology of a paradigmatic chaotic scattering problem as the one taking place in the open nonhyperbolic regime of the Hénon-Heiles Hamiltonian system. We have found long transient...

Three methods of obtaining the Mie scattering function are considered and compared . Legendre polynomials and Clebsh-Gordon coefficients are employed and an exact expression for the expansion of the Mie kernel in spherical harmonics is given . 1 . Introduction The absorption and scattering of electromagnetic radiation by a sphere of arbitrary size and refractive index is an exactly solvable pro...

We have performed time-of-flight neutron scattering measurements on a single crystal of the intermediate valence compound CePd3. At 10K, a Kondo-esque inelastic magnetic scattering peak occurs near DE 1⁄4 60meV with maximum intensity for momentum transfer Q near the ð 2 ; 1 2 ; 0Þ zone boundary. Spectral weight is transferred to lower energy as Q varies until at zone center the intensity at 60m...

We describe a gas-phase x-ray scattering experiment capable of capturing molecular motions with atomic spatial resolution and femtosecond time resolution. X-ray free electron lasers can deliver intense x-ray pulses of ultrashort duration, making them suitable to study ultrafast chemical reaction dynamics in an ultraviolet pump, x-ray probe scheme. A cell diffractometer balances sample flow with...
