Environmental regulations are continuously pushing lower emissions with an impact on the combustion process in gas turbines (GTs). As a consequence, GT combustors operate in very lean regimes (i. e., at relatively low temperature) to reduce NOx formation. Unfortunately, stabilization becomes a challenge for these lean premixed flames. The extremely unsteady dynamics of swirl stabilized flames pres

Large eddy simulations (LES) are performed for single and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow ratios but with droplets of different sizes. Multiphase JICF have stronger counterrotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover, their trajectories are higher and their induced wa

he nearby meadows during a number of days, in order to increase the production. During 1991 it has been tested, in two places in Scania (the southernmost part of Sweden), as a system for removing nitrogen from river water. The nitrogen removal measured through mass balance budget is compared with directly measured plant uptake and denitrification. At the first site, Vombs ängar near Vombsjön, wher

Vitrectomy requires the substitution of the natural vitreous, as well as tamponading of retinal breaks. Clinically available alternatives such as gas and silicone oil have side effects such as inflammation, secondary glaucoma, cataract, and a need for head posturing. In this study, a hydrogel of cross-linked sodium hyaluronic acid (Healaflow(®)) is evaluated for use as a novel vitreous substitute.

Context: When using the Case Method in teaching situations, problem-solving is emphasized and taught, in order to acquire the skills and later be able to apply them in new situations. The basis of the learning process is the students’ own activity in the situation and is built on critical appraisal and discussion. Objectives: To explain what the Case Method is, what it is not and to describe when

Att ersätta vårdgivare baserat på prestation och kvalitet har blivit ett allt vanligare inslag inom vården och ett allt mer beprövat sätt att skapa incitament till förbättrad vårdkvalitet. Syftet med denna uppsats är att undersöka effekten av så kallad målrelaterad ersättning på kvaliteten i den vård av patienter med diabetes typ 1 som bedrivs inom den svenska primärvården. Undersökningen består a

Ett sätt för företag att legitimera sitt informationssäkerhetsarbete är genom att upprätta ett ledningssystem för informationssäkerhet, även kallat LIS. Genom ett LIS kan ett tydligt värde uppvisas mot kunder och andra intressenter. Ett införande av ett LIS kan däremot påverkas av olika typer av faktorer, exempelvis säkerhetsmedvetenhet, ledningen, kostnad och policys och regelverk. Faktorerna kan
