Some European species of the genera Parmelia and Punctelia are analysed using molecular, morphological and chemical characters and notes on their distribution are presented. ITS sequences were compared from a total of 31 representative specimens. Parmelia ernstiae and P. serrana form a sister group to P. pinnatifida and P. saxatilis, whereas P. discordans and P. omphalodes are closely related and

The struggle for equality is fundamental to the reduction of poverty in Central America. Besides, one of the foremost goals of urban spatial planning, when implementing social policies, is to contribute to the reduction of poverty. This is done by producing a list of territorially-based actions and selecting those suitable for the implementation of social policies developed at national level. Howe

The secondary clarifier or settler is crucial for the whole activated sludge operation. Consequently, it is important to obtain a reliable analytical model as well as a useful numerical method, which can be used in the automatic control of the settling process. Discontinuities (shocks) appear physically, and an analytical description as well as a stable numerical algorithm must be able to handle t

Swedish translation of steps 8, 13 and 14 of The Ladder of Divine Ascent by John Climacus. The translation is based upon Rader's edition reprinted in Migne's Patrologia Graeca, vol.88 (Paris, 1633).

The dissertation studies the determinants of self-employment entry through an economics of entrepreneurship lens, and examines two sources of data: 7 years of employer--employee matched panel data and a laboratory experiment. The results suggest that employees are more likely to take the leap to self-employment when they have their own business idea, and are employed in occupations with high wage

Popular Abstract in Swedish Ett antal resultat med anknytning till den geometriska tolkningen av dispersiva ickelinjära vågekvationer presenteras. Det beskrivs först hur några välkända ekvationer för grunt vatten uppkommer geometriskt som Euler ekvationer för det geodetiska flödet på Virasorogruppen försedd med särskilda högerinvarianta metriker. För en av dessa ekvationer?Camassa-Holm ekvationen?A number of results related to the geometric interpretation of some dispersive nonlinear wave equations are presented. It is first described how some well-known shallow water equations arise geometrically as Euler equations for the geodesic flow on the Virasoro group endowed with certain right-invariant metrics. For one of these equations?the Camassa-Holm equation?we demonstrate how geometric meth
