Otryggheten vid kollektivtrafikresor är relativ hög. Drygt hälften av vaneresenärerna har känt sig otrygga i samband med en kollektivtrafikresa. Även om de allra flesta endast har känt otrygghet ibland, kan detta leda till att människor reser mindre kollektivt än de önskar; att de hellre kör bil eller att deras rörlighet minskar. För att minska otryggheten vid kollektivtrafikresor kan det vara nöd

UPPLEVELSER AV SVENSK FILM offers a broad understanding of Swedish cinema during the years between 1985 and 2000. The dissertation focuses on those Swedish films that have been given a wide distribution, i.e. films that in many cases can be considered popular films. (Films that have only obtained a marginal position in the cinemas have not been included.) The films studied attract an average of 2,

The isolation and structure determination of conidiogenol and conidiogenone, tetracyclic diterpenes with a novel carbon skeleton, from extracts of the fermentation broth of Penicillium cyclopium is reported. Conidiogenol and conidiogenone are potent and selective inducers of conidiogenesis in P. cyclopium in liquid culture, and relay information about the environmental conditions to the producing

A new beam line for generating a sub-micron beam spot for high-resolution nuclear microprobe applications has been constructed at the Lund nuclear microprobe facility. In this paper, the first in a series of three, a detailed theoretical investigation of different focusing systems is presented based on calculations performed with the computer programs PRAM and OXTRACE. Comparison is made between a

Popular Abstract in Swedish Syftet är att dels studera olika ventilationssystems förmåga att tillföra och föra bort luftflöden. Den andra delen av syftet är att studera konstruktionskriterier och energi användning för ett variabelflödessystem baserat på konstanttryckshållning av det statiska trycket på grenkanalnivå och som endast tillför uteluft. Ventilationssystemens luftflöden studeras med hjälOne part of the objective is to analyze how different ventilation systems perform in practice when it comes to supplying and exhausting designed air flow in different outdoor and indoor conditions. The other part is to analyze the design criterias and the energy use of a variable air volume system based on controlled static pressure at the branch duct level and supplying outdoor air only. To inves

Background: Since the cloning in 1990 of cDNA corresponding to mRNA transcribed at the blood-group ABO locus, polymorphisms due to ethnic and/or phenotypic variations have been reported. Some subgroups have been explained at the molecular level, but unresolved samples are frequently encountered in the reference laboratory. Results: ABO blood grouping discrepancies were investigated serologically a

In 98 patients undergoing elective vascular surgery, specimens for bacterial cultures were obtained from urine, ischaemic ulcers, incisional wounds and the implanted grafts. Wound and graft infections were registered and compared with the results of these cultures and suspected risk factors in an attempt to find the source of infections. Antibiotic prophylaxis with cefuroxime was given for 24 h be

Popular Abstract in Swedish Återkoppling är en fundamental princip inom reglertekniken. Genom att mäta vissa variabler kan andra påverkas så att ett system uppför sig på önskat vis. Denna doktorsavhandling behandlar två typer av återkoppling: reläåterkoppling och flervariabel återkoppling. Reläåterkoppling är den enklaste formen av återkoppling. Endast tecknet på en uppmätt variabel återkopplas: This doctoral thesis treats three issues in control engineering related to relay feedback and multivariable control systems. Linear systems with relay feedback is the first topic. Such systems are shown to exhibit several interesting behaviors. It is proved that there exist multiple fast relay switches if and only if the sign of the first non-vanishing Markov parameter of the linear system is pos

Software quality can be defined as the customers' perception of how a system works. Inspection is a method to monitor and control the quality throughout the development cycle. Reading techniques applied to inspections help reviewers to stay focused on the important parts of an artifact when inspecting. However, many reading techniques focus on finding as many faults as possible, regardless of thei
