The primary route to hydrogen production from fossil fuels involves the water-gas shift (WGS) reaction, and an improvement in the efficiency of WGS catalysts could therefore lead to a major leap forward in the realization of hydrogen economy. On the basis of a combination of high-resolution scanning tunneling microscopy, X-ray photoelectron spectroscopy, and density functional theory (DFT) calcula

Den typ av krisbegrepp som detta kapitel utgår ifrån är processuell; denna betonar den allmänna karaktären av situationer, men utan hänsyn till specifika kriser. Den allmänna situation som analyseras handlar om den svenska välfärdsstaten som mytbildning (ca 1945–1960): Vilka medel krävs för att skapa ett bättre fungerande samhälle, och utgör dessa medel ett hinder snarare än en möjlighet för den e

Popular Abstract in Swedish Den svenska grundskolan har under de senaste åren genomgått och genomgår fortfarande en stark utveckling inom ramen för den allmänna decentraliseringen i samhället. Beslut och ansvar läggs allt längre ner i organisationen. De krav som ställdes på en skolledare tillbaka i tiden var i första hand att han skulle vara administratör och den som bevakade att skolans verk-samThe issues of the study are: How do the assistant principals face the work as school leaders? Which demands of competence do the new school leaders face? Which needs of competence development exist for new school leaders? In the school studied the organization of the management was changed from one principal and one director of studies to one principal and six assistant principals. All of these we

This article discusses the heteronormative reception of the Swedish teen movie "Show Me Love" (1998). It is a love story between two teenage girls, but the reviews hardly mentioned the young lesbian love story.

Transmitted vibrations from water-pipe systems, involving supports standing on a concrete slab and the underlying ground, are investigated here. The effects of varying parameters of the supports, such as location, their elastic modulus and their cross-section, on the level of vibrations transmitted by the water-pipe system are analysed in order to minimise vibrations transmitted to sensitive parts

Understanding the relationship between concepts and experience seems necessary to specifying the content of experience, yet current theories of concepts do not seem up to the job. With Peter Gärdenfors's conceptual spaces theory as a foundation and with enactivist philosophy as inspiration, we present a proposed extension to conceptual spaces theory and use it to outline a model of the emergence o

Teamwork and project participation are essential skills for professional software engineers. To be able to give large groups of students adequate opportunities to learn such skills at a reasonable teaching cost, we have developed two courses that work in tandem: a team programming course taken by about 100 students, and a coaching course taken by about 20 students. In this paper, we describe our v

Microelectronics promises a high component density and low power dissipation to embedded systems. Unfortunately such a component will always suffer from various error types that make the chip respond differently from its functional simulation. This is especially true for Cellular Neural Networks (CNN), which makes the determination of robust, low-precision parameters to guarantee small footprint a

The subject of the dissertation is the influence of shorter working days on welfare. The focus is the reduction of paid daily working hours as an instrument for better working conditions and a better life. The empirical study is based on a hospital where working hours have been reduced in four wards by one hour a day in three of the geriatric nursing departments. The aim of the dissertation was t
