The purpose of this study was to develop new prediction equations for flow/volume spirometry parameters in asymptomatic, never-smoking adults in Norway, and to assess any differences of these parameters when applying the new and most commonly used equation sets. Flow/volume spirometry was measured according to the American Thoracic Society criteria in 2,792 subjects aged > or = 20 yrs, randomly se
A new type of two-color four-wave mixing spectroscopy is theoretically and experimentally demonstrated. By employing a non-resonant pumping and resonant probing scheme, OH radicals are detected in a laminar, atmospheric pressure methane/air flame as a proof-of-principle experiment. Two 532 nm laser beams from a multi-mode Nd:YAG laser are utilized to create an electrostrictive grating in the flame
Clinical applications of blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) depend heavily on robust paradigms, imaging methods and analysis procedures. In this work, as a means to optimize and perform quality assurance of the entire imaging and analysis chain, a phantom that provides a well known and reproducible signal change similar to a block type fMRI experiment
A new optical-fibre radiation dosimeter system, based on radioluminescence and optically stimulated luminescence from carbon-doped aluminium oxide, was developed and tested in clinical photon beams. This prototype offers several features, such as a small detector (1 x 1 x 2 mm), high sensitivity, real-time read-out and the ability to measure both dose rate and absorbed dose. The measurements descr
A plasma source free from characteristic emission lines is described, based on laser irradiation of a water jet in a helium atmosphere. Various key aspects of the laser interaction are presented along with practical characterization of the observed isotropic ~4–10 keV x-ray emissions, measurements of which indicate subpicosecond duration. Observations are consistent with a vacuum heating plasma me
Reagentless amperometric biosensors for glucose and ethanol were developed and successfully applied for monitoring glucose and ethanol concentrations in wine during the fermentation process. The glucose biosensor was based on commercially available glucose oxidase and horseradish peroxidase co-immobilized on solid graphite using Os(II)-redox hydrogel (RH) [1]. In the case of ethanol biosensor, the
Most foot-propelled swimming birds sweep their webbed feet backwards in a curved path that lies in a plane aligned with the swimming direction. When the foot passes the most outward position, near the beginning of the power stroke, a tangent to the foot trajectory is parallel with the line of swimming and the foot web is perpendicular to it. But later in the stroke the foot takes an increasingly t
Objectives. This research was conducted to demonstrate the effectiveness of reflective photoelasticity as an in vivo technique for monitoring the strain/stress distribution in prosthetic devices during function. Methods. Seven subjects were selected for this study and divided into three groups according to the design of the prostheses. The buccal surfaces of the experimental prostheses were coated
High-resolution nuclear magnetic resonance spectra from samples located in inhomogeneous static and radio frequency magnetic fields can be obtained by applying a train of z-rotation radio frequency pulses to repeatedly refocus the inhomogeneous broadening during signal detection. z-rotation pulses based on an adiabatic double passage are effective over wide bandwidths using a limited amount of rad
Popular Abstract in Swedish Denna avhandling fokuserar en religiös aktör i det civila samhället under en konfliktfylld tid. Judiska, muslimska och kristna barn studerade tillsammans i anglikanska missionsskolor under den brittiska mandattiden i Palestina. Jerusalem var då etniskt och religiöst delat. Det anglikanska utbildningsprojektet var en del av den Anglikanska kyrkans försök att främja konflThis thesis concerns a religious actor in the civil society in times of violent conflict. During the British Mandate period in Palestine, Jewish, Muslim and Christian children studied together at Anglican missionary schools. At this time Jerusalem bore all the imprints of ethnic and religious separation and division. The Anglican educational project became part of the efforts made by the Anglican
Objective: To evaluate the efficacy of individual trauma-focused cognitive-behavioral therapy (CBT) for treating posttraumatic stress disorder (PTSD) in children and young people. Method: Following a 4-week symptom-monitoring baseline period, 24 children and young people (8Y18 years old) who met full DSM-IV PTSD diagnostic criteria after experiencing single-incident traumatic events (motor vehicle
EPR spectroscopy has been employed to determine the nature of vanadium (+4) species in the TiO2(B)-supported vanadia catalysts. IR and EPR studies show that multiple vanadia species are observed as a function of loading. At coverages greater than 3.5 theoretical layers, the EPR signal is reminiscent of bulk V205. At lower coverages, a different magnetic species dominates the resonance and may be a
Sorption isotherms (moisture content as a function of relative humidity (RH) at equilibrium) are an important tool in designing buildings to limit moisture related problems. Normally only a single sorption curve is used so that each moisture content uniquely corresponds to one RH. Sometimes two curves are used, one curve for absorption and one for desorption, as it is well known that sorption has
Popular Abstract in Swedish Cellulosa och stärkelse är naturligt förekommande polysackarider, som är uppbyggda av långa rader av flera tusen sammanbundna glukosmolekyler. De är biologiskt nedbrytbara, billiga och dessutom förnyelsebara, och används mycket som råvaror i läkemedels-, livsmedels-, textil-, pappers- och byggnadsindustrin. För att cellulosa och stärkelse ska kunna användas industrelltCellulose and starch are non-toxic, biodegradable and modifiable polymers. These properties have made them increasingly important in industrial products e. g. in pharmaceutical applications and in technical dispersions. By chemical modification of these polymers the physical and chemical properties of the polymer can be adjusted to suit a certain area of application. The characteristics of modifie
