Differential scanning calorimetry (DSc) and dynamic light scattering (DLS) were used to obtain the gel to liquid-crystalline phase transition temperature (T-m) and the apparent hydrodynamic radius (R-h) of spontaneously formed cationic vesicles of dialkyldimethylammonium bromide salts (CnH2n+1)(2)(CH3)(2)N+center dot Br-, with varying chain lengths. The preparation of cationic vesicles from aqueou

MnAs layer has been grown by means of MBE on the GaN(000 (1) under bar)-(1 x 1) surface. Spontaneous formation of MnAs grains with a diameter of 30-60 nm (as observed by atomic force microscopy) occurred for the layer thickness bigger than 7 ML. Ferromagnetic properties of the layer with Curie temperature higher than 330 K were detected by SQUID measurements. Electronic structure of the system was

PURPOSE: To measure the apparent diffusion coefficient (ADC) of hyperpolarized (HP) (3)He gas using diffusion weighted MRI in healthy volunteers and patients with emphysema and examine the reproducibility and volume dependency. MATERIALS AND METHODS: A total of eight healthy volunteers and 16 patients with emphysema were examined after inhalation of HP (3)He gas mixed with nitrogen (N(2)) during b

Diagnosis by screening mammography is considered an independent positive prognostic factor, although the data are not fully in agreement. The aim of the study was to explore whether the mode of detection (screening-detected versus symptomatic) adds prognostic information to the St Gallen molecular subtypes of primary breast cancer, in terms of 10-year cumulative breast cancer mortality (BCM).

Popular Abstract in Swedish I min avhandling har jag sökt den kinesiska barnbokens litterära rötter. Jag har studerat dess utveckling och dess samband med författaren Zhang Tianyi, som enligt den officiella bilden betraktas som en av föregångarna på barnlitteraturens område. Kinesisk barnlitteratur är ett outforskat område, trots att källmaterialet är rikt. Avhandlingen studerar barnlitteratur i eThis thesis investigates the origin of children's literature in China and traces its evolution in connection with the author Zhang Tianyi, who is officially considered as one of the forerunners of Chinese children's literature. Children's literature in China is a little studied field, although the sources for a study are abundant. The thesis studies children's literature in its social context, whi

Popular Abstract in Undetermined Syftet med avhandlingen är dels att undersöka författarbiografin som litterär text, dels att finna en rimlig ståndpunkt i den teoretiska debatt där biografins fiktionalitet har lyfts fram. I inledningen tar jag upp den teoretiska utveckling som rör detta metaperspektiv. För att ge en ram både åt dessa resonemang och mitt eget val av undersökningsobjekt, ger jag ockThe aim of the present thesis is twofold: to examine literary biography as literary text and, on the basis of my findings, to adopt a reasonable perspective on the theoretical debate about the fictionality of such biographies. In my introduction I trace the theoretical developments underlying this metaperspective and supply with an historical survey of literary biography as practised in Sweden. In

Lattice Boltzmann method (LBM) is alternative computational method to the traditional computational fluid dynamic (CFD) methods. LBM has the ability to with straightforward computational procedure to handle the detail activity at microscale well for simulation of different transport processes. In this study the focus is on the effects of electrochemical reactions and transport processes in an anod

To improve gas turbine performance, the operating temperature has been increased continuously. However, the heat transferred to the turbine blade is substantially increased as the turbine inlet temperature is increased. Cooling methods are therefore needed for the turbine blades to ensure a long durability and safe operation. The blade tip region is exposed to the hot gas flow and is difficult to

In this study a dynamic model of a solid oxide fuel cell (SOFC) system has been developed. The work has been conducted in a cooperation between the Department of Energy Sciences, Lund University, and Mode Ion AB using the Modelica language and the Dymola modeling and simulation tool. Modelica is an equation based, object oriented modeling language, which promotes flexibility and reuse of code. The

This paper explores the use of spreadsheets in budgeting in order to explain how and why spreadsheets are used or not used in budgeting practice. Guided by modern budgeting research, budgeting is considered as a social phenomenon which requires flexibility for decision-making and integration for management control. Twenty-one interviews with business controllers in eleven leading for-profit organi

The implementation of anti-windup methods in mid-rangingcontrol needs further attention. It is demonstrated how use of standard anti-windup schemes may give unnecessary performance degradation during saturation. The problem isillustrated for two separate systems, control of oxygen concentration in a bio-reactor and temperature controlof a cooling system. In the paper, guidelines are derived for ho

Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. The paper discusses a pipelined implementation that supports the handling of gray-level images at 180 to 240 Mpixels per second by exploiting the Virtex-II macros to spatially unroll the local feedback
