Mixed phase (rutile/anatase)TiO2 nanorods have been synthesized using an anionic surfactant template. Nanorod synthesis has been achieved using mild reaction conditions and without using any rod-shaped template. The shape and crystallinity of the TiO2 nanomaterials can be modulated by careful control of the surfactant concentration. The novelty of the present work is that the anatase/rutile mixed

A series of conformationally restricted N-"furanosides" has been synthesized, where the carbons of the tetrahydrofuran ring are kept in one plane by a rigid norbornane skeleton, permitting only the ring oxygen to move above or below the tetrahydrofuran ring plane. This causes the substituents of the anomeric carbon to occupy a pseudoaxial or a pseudoequatorial position. On protonation of these "no

A total of 47 firms joined the Swedish EKO-Energi programme between 1994 and 1997. This was a public voluntary programme devoted to promoting the environmental vanguard, while disregarding the rearguard. The programme offered free energy audits and the promotion of a label, in return for implementation of energy management. Audits covered some 5% of industrial energy consumption. The most clearly

We have investigated terahertz (THz) emission due to dynamical electron transport in wide miniband GaAs/Al0.3Ga0.7As superlattices. By noting that the time-domain THz emission spectroscopy contains the information on the step response of the electron system to the bias electric field, the obtained THz spectra were compared with the high-frequency conductivities predicted for miniband transport. Ex

This paper critically reviews reconstructions of cultural development in prehistoric Amazonia and argues for the primacy of regional and interregional exchange in generating the complex distributions of ethno-linguistic identities traced by linguists and archaeologists in the area. This approach requires an explicit abandonment of notions of migrating "peoples" in favor of modern anthropological u

The aim of this study was to establish tolerable fire risk criteria for hospitals. The event tree technique was used to assess the safety level in a model hospital building. Risk profiles were derived and tolerable criteria established by evaluating the risk. The motivation behind this methodology is that buildings designed completely in accordance with today’s regulations must be considered safe

In this study a set of structures has been simulated to represent a range of clinically relevant breast cancer mammographic lesions including solid tumours and microcalcifications. All structures have been created using simple random-based mathematical functions and have been inserted into a subset of digital mammography images at appropriate contrast levels into various regions of the breast, inc

Purpose: To evaluate the functional disorders of the oral and pharyngeal phases of deglutition after repair of esophageal atresia in children. Material and Methods: 19 children (10 girls, 9 boys, mean age 22 months) underwent videofluoroscopy of deglutition after repair of esophageal atresia. The videofluoroscopic studies were assessed according to functional and morphological changes in the oral,

The NorduGrid is the pioneering Grid project in Scandinavia. The purpose of the project is to create a Grid computing infrastructure in Nordic countries. The cornerstone of the infrastructure adopted at NorduGrid is the Globus toolkit developed at Argonne National Laboratory and University of Southern California. It is, however, missing several important high-level services. With the need to provi

The conductive polymer poly(2-methoxy-5-(2'-ethylhexyloxy)-1,4- phenylene vinylene) (MEH-PPV) was investigated by means of single molecule spectroscopy at 15 K. MEH-PPV single chains were deposited onto a surface from a toluene solution and covered with a polymer cap layer spin-coated from an aqueous solution for protection from air. The MEH-PPV molecules exhibited large fluorescence spectral diff

In recent decades we have witnessed a proliferation of new kinds of retail space. Retail space has cropped up just about everywhere in the urban landscape, at libraries, workplaces, churches and museums. In short, retail is becoming a more and more manifest part of the public domain. The traditional spaces of retail such as city centres and outlying shopping malls are either increasing in size or

This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. When the error score for the first test opportunity is compared with th

Globalization pressures have today inflicted significant changes in the way industrial enterprises are organized and how products are developed, manufactured and brought to market. A common denominator in many of these enterprises is the utilization of an organizational structure based on networks composed of divisions and supplier companies dispersed all over the world. ln these global enterprise

Popular Abstract in Swedish Syftet med denna avhandling var att undersöka olika aspekter på intersubjektivitet, metakognitiv utveckling och mellanmänsklig förståelse. Mer precist var syftet att undersöka hur några specifika teorier – mentaliseringsteorin, teorin om primär intersubjektivitet, samt interaktionsteorin – beskriver vilken roll intersubjektivitet har att spela i denna utveckling. De förThe aim of the thesis was to examine different aspects of the role of intersubjectivity in metacognitive development and in social understanding. More specifically, it investigates how different theoretical frameworks, such as mentalization theory, the theory of primary intersubjectivity, and interaction theory describe the developmental role of intersubjectivity. The suggestions these theories ma

Reaction of N-(2-hydroxybenzyl)-N-(2-picolyl) glycine (H(2)papy) with VOSO(4) in water gives the oxidovanadium(V) oxido-bridged dimer [{(papy)(VO)}(2) μ-O)] (1). Similarly, reaction of N-(2-hydroxybenzyl) glycine (H(2)glysal) with VOSO(4) gives [(glysal)VO(H(2)O)] (2) and reaction of salicylamide (Hsalam) with VOSO(4) in methanol gives [(salam)(2)VO] (3). The crystal structure of the oxido-bridged

The article aims at making visible new orders of encyclopaedic knowledge by means of an ethnographic study carried out during eight months at the editorial office of the leading commercial encyclopaedia in Sweden, Nationalencyklopedin. The investigation is framed in a socio-technical understanding of how people, technologies and practices relate to each other. Three themes were identified during t
