Abstract in UndeterminedThis thesis consists of five self-contained chapters: Chapter 1:Effects of driving restrictions on air quality and car use in Bogota Rationing car use at certain times of the day based on license plate numbers has become a popular policy to address traffic congestion and air pollution in several cities around the world. This paper analyzes the effects of moderate and drasti

Daß Schweden während der sogenannten Großmachtzeit (1620-1720 ) enge Beziehungen zu den europäischen Kulturländern unterhielt, ist allgemein bekannt. Was aber war nach der Großmachtzeit geschehen, in der Zeit nach den Kriegszügen Karls XII., also während der sogenannten Freiheitszeit zwischen 1720 und 1771? Das Repertoire der Hofkapelle aus diesen Jahren ist größtenteils verschollen. Die beiden Un

Gas chromatographic methods for the determination of cyclic organic acid anhydrides (OAAs) in industrial air are reviewed. The OAAs discussed are phthalic, hexahydrophthalic, methylhexahydrophthalic, tetrahydrophthalic, methyltetrahydrophthalic, trimellitic, maleic, and octenylsuccinic anhydride. Solid sorbent sampling methods, using Amberlite XAD-2 or Tenax, are used for sampling of OAA vapour. T

När man möter en mamma eller pappa berättar de kanske om sitt barn. Men är barnen deras? I många andra sammanhang talas det om våra barn: skolan, sjukvården, föreningar gör också anspråk på att äga barnen. Världen kring handikappade barn sätter förhållandet på sin spets: där finns en myriad av yrken och institutioner, som hävdar att de både vet mer och vet bäst. Experternas kunskaper är eftersökt

When the Ostra Torn area of Lund, Sweden was further developed in the 1990s, storm water was connected to the old separate storm water system. This increases the risk of flooding near the connection points. In this paper, the function of the system is analyzed using Storm Water Management Model SWMM. Consequences of extreme storms are investigated: It is shown that it is not necessary to connect t

A 10 GHz beam forming transmitter was designed in a 90 nm CMOS process. Two power amplifiers with independently controllable phase enable the beam forming. The controllable phase is accomplished by switching in binary weighted transistors fed by quadrature signals, which are generated by a quadrature voltage controlled oscillator followed by a buffer. The design contains seven differential on-chip
