INTEGRAL observations of the peculiar BeX System SAX J2103.5+4545

2004

We present an INTEGRAL data analysis of the X-ray transient \object{SAX J2103.5+4545} during two outbursts detected in December 2002. The INTEGRAL coordinates and error circle agree with the position of the recently proposed optical counterpart. A power-law plus cut-off model provided a good fit to the 4-150 keV spectrum yielding a photon index of 1.0+-0.1, a cut-off energy E_cut=7.6+-2.0 keV and a folding energy E_fold=30.9+-2.5 keV. The X-ray luminosity in the 4-150 keV energy range was found to be 6.0x10^36 erg/s, assuming a distance of 6.5 kpc. This luminosity, together with the derived photon index, indicate that the source is in a bright state. A 354.9$+-0.5 second pulse period is mea…

Effects of post-growth annealing on structural and compositional properties of the Co2Cr0.6Fe0.4Al surface and its relevance for the surface electron…

2009

In this study we investigate the influence of post-growth annealing on different Co2Cr0.6Fe0.4Al samples. We find strong changes in the geometric surface structure as well as in the element specific concentrations during the annealing process. These irreversible changes go in hand with characteristic changes in the electron spin polarization (ESP) at the surface: as observed in Cinchetti et al (2007 J. Phys. D: Appl. Phys. 40 1544), the iron buffered sample shows the largest spin polarization at the Fermi level. The latter remains positive as a consequence of the reduced density of states for the minority carriers due to the predicted minority gap, which can be clearly seen for all samples …

From Biology to Linguistics

If we want to get to the bottom of the definition of ἄρθρον in the Poetics, in my opinion we have to work hard in several directions. First of all, it should be vigorously emphasized that the definitions of σύνδeσμος and ἄρθρον in the Poetics are aimed at the subsequent definition of λόγος [This is very aptly pointed out already in Bywater (1909, p. 270).]. This definition recognizes two types of λόγος: the λόγος that is unitary by itself and the λόγος that is unitary thanks to a connector (Poet. 1457 a 27-30: eἷς δέ ἐστι λόγος διχῶς, ἢ γὰρ ὁ ἐκ πλeιόνων συνδέσμῳ, οἷον ἡ Ἰλιὰς μὲν συνδέσμῳ eἷς, ὁ δὲ τοῦ ἀνθρώπου τῷ ἓν σημαίνeιν. See Met. Ζ 4, 1030 a 9, b 5-10; H6, 1045 a 12-14.). Now, if th…

Aeration tank and secondary clarifier as one system. in "Activated Sludge Separation Problems: Theory, Control Measures, Practical Experieces. Eds. R…

2017

Traditionally the activated sludge process is treated as two stage process. The first stage (aeration basin) is described in terms of biological processes while the description of the second stage concentrates on processes of biomass separation and thickening. The modern approach to the activated sludge process looks at both the biological and the separation stage as one system. The aim of this chapter is to explain the interactions between the two parts of the activated sludge system.

ChemInform Abstract: High-Resolution Solid-State NMR Spectroscopy of Steroids and Their Derivatives

2013

Abstract: Steroids are an important class of organic compounds containing a vast array of biologically and physiologically essential molecules. Due to their availability, relatively straightforward derivatizability, and endogeneity, they are widely used in pharmacological applications. The investigation of molecular and physicochemical properties of active pharmaceutical ingredients (APIs) in the solid state is important, because these properties are directly related to their pharmacological activity. Several methods are available for this purpose. Solid-state NMR spectroscopy offers a nondestructive and flexible technique, providing both structural and dynamic information. It can be applie…

Reply to comment on “A MRCI PS and CASSCF study of the ground state MgO dissociation energy”

1993

To compute the dissociation energy of MgO, the relationship among the size of the active space in CASSCF wavefunctions, the computed De and the continuity of ∂E/∂r is studied. Basis set influence is also considered. Finally, it is concluded that the dissociation energy of MgO referred to ground state atoms is 2.32±0.1 eV.

Thermodynamic properties of a liquid–vapor interface in a two-component system

2010

Abstract We report a complete set of thermodynamic properties of the interface layer between liquid and vapor two-component mixtures, using molecular dynamics. The mixtures consist of particles which have identical masses and diameters and interact with a long-range Lennard-Jones spline potential. The potential depths in dimensionless units for like interactions is 1 (for component 1) and 0.8 (for component 2). The surface excess entropy decreases when the temperature increases, so the surface has a negative excess heat capacity. This is a consequence of the fact that the surface tension decreases to zero at the critical point, proportional to ( T C , i − T ) 2 ν . The surface entropy decre…

Trends in individual reimbursement of orphan drugs in Latvia in 2008–2011

2014

Orphan drugs (ODs) are medicinal products intended for diagnosis, prevention or treatment of life-threatening or very serious diseases affecting less than 5 in 10 000 people in the European Union (EU). These drugs are called “orphans” because the pharmaceutical industry has little interest, under normal market conditions, in developing and marketing products intended for only a small number of patients suffering from very rare conditions. Because of the small market, ODs are often very expensive. Whereas decisions surrounding orphan designation and marketing authorization of ODs are taken at the EU level, decisions governing pricing and reimbursement of ODs are a member state responsibility…
