Context. The Yarkovsky effect is a weak non-gravitational force leading to a small variation of the semi-major axis of an asteroid. Using radar measurements and astrometric observations, it is possible to measure a drift in semi-major axis through orbit determination. Aims. This paper aims to detect a reliable drift in semi-major axis of near-Earth asteroids (NEAs) from ground-based observation...

The glass properties and semi crystalline properties of polymers are observable by X-ray diffraction. Some previous works 1, 2, 3 were about determination of degree of crystallinity of sPS by various technologies, like for example DSC, XRD and Raman spectroscopy. The purpose of this paper is to show importance of Raman spectroscopy as analytical tool for the study of amorphous and semi-crystall...

We present a phenomenological analysis of data on both inclusive and semi-inclusive spin asymmetries. We examine the impact of the semi-inclusive results presented by SMC on the determination of polarized parton distributions performing global fits with different sets of observables. We discuss the flavour dependence of the polarized sea inside a nucleon.

A reliable automated approach for assignment of NOESY spectra would allow more rapid determination of protein structures by NMR. In this paper we describe a semi-automated procedure for complete NOESY assignment (SANE, Structure Assisted NOE Evaluation), coupled to an iterative procedure for NMR structure determination where the user is directly involved. Our method is similar to ARIA [Nilges e...
