In this study the deactivation of Pt/wire mesh and vanadia/monolith catalysts by aerosol particles of some inorganic salts (K2SO4, KCl and ZnCl2) with high or low melting points has been investigated. The aerosol particles may either diffuse within the matrix of the catalysts and block the mezzo and micro pores, or deposit on the outer surface of the catalysts and form a porous layer causing a mas
We propose a technique to integrate core selection in the SOC (system-on-chip) test solution design-flow. It can, in contrast to previous approaches, be used in the early design-space exploration phase (the core selection process) to evaluate the impact on the system's final test solution imposed by different design decisions, i.e. the core selection and the cores test characteristics. The propose
Basic principles for the extension of gas-correlation techniques to the lidar situation are discussed. Favorable signal-to-noise ratios and relaxed laser requirements characterize the technique. Preliminary experiments on atomic mercury are reported.

The need to reduce CO2 emissions from fossil-fuel based power production creates the need for new power plant solutions where the CO2 is captured and stored or reused. Oxygen Transfer Membrane (OTM) is the key component of oxy-fuel combustion processes as pure oxygen is usually required to process reactions (e.g. Natural Gas Combined cycle NGCC, Pulverised Coal-fired power plants PC-plants, Integr
Solen skiner, fåglarna kvittrar och blommorna doftar. Den bild av naturen som framträder i svaren på frågelistan "Naturen för mig" rör sig i hög grad om det vackra, det fina och det trevliga. Men i mörkret lurar vildsvin och mördarsniglar.
We study various differential equations subject to constraints. In the first part we study a partial differential equation, Burgers equation, subject to time-periodicity constraint. The forcing term is time-periodic and may be highly irregular. We prove an existence and uniqueness result which in a sense is optimal since we show that the operator corresponding to the Burgers equation is a diffe
Divorce cases in the Karlskrona Admiralty Consistory are compared to those in the City of Stockholm. The result is that the mobility in Karlskrona was as high as in Stockholm, but without tendencies to religious or social separation from the Church. A social control was hard to maintain among seamen and wives, but stronger than in the more diversified capital.
Inom lärarutbildningen vid Högskolan i Halmstad har handledning och examination av lärarstudenternas examensarbete nyligen förändrats. Studenterna handleds nu i grupper av handledarpar, vilka i sin tur ingår i ett lag som coachas av en kollega. Examinationen av examensarbetena har också förändrats i och med att examinatorer som är externa i förhållande till handledningen införts. Vidare har nya be
The rapid development of wireless sensor network and RFID technologies offers a wide range of novel applications and services. In this paper, we present a two-layered wireless network for warehouses and supermarkets to monitor goods storage and sale, and assist for quality management and market analysis. The hierarchical architecture uses IEEE 802.15.4a impulse ultra-wideband radio (IR-UWB) commun
