We use the two-zone model of Cooper & Narayan to study the onset and time evolution of hydrogen-triggered type I X-ray bursts on accreting neutron stars. At the lowest accretion rates, thermally unstable hydrogen burning ignites helium as well and produces a mixed hydrogen and helium burst. For somewhat higher accretion rates, thermally unstable hydrogen burning does not ignite helium and thus ...

We study the secular instability of magnetized differentially rotating radiative zones taking account of viscosity and magnetic and thermal diffusivities. The considered instability generalizes the well-known Goldreich-Schubert-Fricke instability for the case of a sufficiently strong nagnetic field. In magnetized stars, instability can lead to a formation of non-spherical unstable zones where w...

By means of a dynamic panel data analysis, and using a database from municipalities of the province of Barcelona (1993-99), we describe their process of fiscal adjustment to a shock in tax capacity. About 25% of the shock is internalized through an increase in tax effort, 35% through a reduction in public expenditure (mainly investment), while the rest is covered by an increase in the level of ...

although improvement and accumulation of human capital  depends on state policy, every state hasn't this capability. meritocratic bureaucracies, extractive capability, accountability and rationalization of relations with society promote capacity and autonomy in developmental state model. according to the study hypothesis, structure and nature of the ninth and tenth governments was the main...

OBJECTIVES To provide an overview of the complicity of British American Tobacco (BAT) in the illicit trade of cigarettes across the African continent in terms of rationale, supply routes and scale. METHODS Analysis of internal BAT documents and industry publications. RESULTS BAT has relied on illegal channels to supply markets across Africa since the 1980s. Available documents suggest smugg...
