Thin layers of GaxIn1-xP grown on top of self-assembled InP quantum dots has been studied using transmission electron microscopy (TEM), scanning tunneling microscopy (STM), and low-temperature scanning tunneling luminescence (STL). STM reveals that the overgrowth is highly uneven, in which elongated GaxIn1-xP islands covering the dots are formed. TEM and high-spatial-resolution STL show that the q
The inclusive e(+)p single and double differential cross sections for neutral and charged current processes axe measured with the H1 detector at HERA. The data were taken in 1999 and 2000 at a centre-of-mass energy of roots = 319 GeV and correspond to an integrated luminosity of 65.2 pb(-1). The cross sections are measured in the range of four-momentum transfer squared Q(2) between 100 and 30 000
Popular Abstract in Swedish Den nuvarande teknologin inom förbränningsmotorer har möjligheten att hantera den alltmer strikta myndighetskraven på förbränningsmotorn. Emellertid de nödvändiga tekniska lösningarna som krävs är dyra och alltmer tekniskt krävande. En möjlig väg mot enklare efterbehandlingssystem är anvädningen av Homogen Kompressions Antändning (Eng: HCCI) motor cykeln. Den huvudsaklThe current technology within combustion engines have the possibility of handling the more stringent legislative demands on combustion engines. However the required solutions are getting more expensive and technically challenging. One possible way towards a more simple exhaust aftertreatment system is the use of the Homogeneous Charge Compression Ignition (HCCI) engine cycle. The main advantage o
Antithyroid treatment for Graves' hyperthyroidism restores euthyroidism clinically within 1-2 months, but it is well known that TSH levels can remain suppressed for many months despite normal free T(4) and T(3) levels. This has been attributed to a delayed recovery of the pituitary-thyroid axis. However, we recently showed that the pituitary contains a TSH receptor through which TSH secretion may
Popular Abstract in Swedish I denna avhandling har användbarheten av Virtual Reality (VR) utvecklats och undersökts för två användningsområden: participatorisk design av arbetsplatser och hjärnskaderehabilitering. Inom det första användningsområdet används VR tillsammans med fullskalemodellering, drama och demokratisk mötesteknik i en Visualiseringsverkstad. Denna arbetsmetod har utvecklats och tIn this thesis, the usability of Virtual Reality (VR) has been investigated and developed within two applications: participatory design of workplaces and brain injury rehabilitation. In the first application, VR is used in combination with full scale modelling, drama and democratic meetings in an Envisionment Workshop. This workshop has been developed and tested through several real workplace int
OBJECTIVE: To determine the diagnostic value of metaiodobenzylguanidine (MIBG) scintigraphy compared with computed tomography (CT) for the localization of phaeochromocytomas in clinical practice. DESIGN: Retrospective comparison between MIBG scintigrams and CT for localization of phaeochromocytomas in all patients successively examined with MIBG scintigraphy in Malmo from 1984 until January 1997.
Popular Abstract in Swedish I avhandlingen studeras hur lärare och studenter uppfattar hälsopedagogik i sjuksköterskeutbildningen. Det är begreppet hälsopedagogik som fokuseras, hur det innebördsligt kan förstås och beskrivas i ett utbildningssammanhang. Intresset för pedagogiskt arbete med hälsofrågor, har sin grund i en övertygelse, att hälsa kan påverkas genom kunskapsbildning. Pedagogiken handThis study is about health pedagogy in nursing education. The main purpose is to describe health pedagogy in the context of nursing education and to increase the understanding for the subject. It is the different experiences of how teachers and students understand the concept, and how this can be related to how health pedagogical knowledge is expressed in the documents which govern nurses' educati
The size and shape of the cockerel comb, ran be regarded as secondary sexual characters or sexual ornaments. Sexual characters are assumed to be costly to express and the expression of a secondary sexual character is suggested to be favourably correlated with the bearer's condition or fitness. The aim of this study was to clarify the effects of selection for male sexual characters, the correlated
We investigated the effects of cell-free filtrates of the cyanobacteria Nodularia spumigena, Aphanizomenon sp. and Anabaena sp. on a brackish-water plankton community (< 150 mu m). In a laboratory experiment, we monitored the concentration of chlorophyll a and cell numbers of bacteria, phytoplankton and ciliates in the experimental units treated with cyanobacterial filtrates and the control medium
The electric field-assisted charge carrier photogeneration in a Ladder-Type Methyl substituted Poly(Para-Phenylene) was investigated by studying the electromodulated ultrafast transient differential absorption spectra and kinetics. The field stimulated appearance of the polaron absorption and quenching of the singlet exciton absorption proves that dissociation of excitons into geminately bound ele
The structural gene LPGVI (1463 bp including 6 introns), characterized from the white-rot basidiomycete Trametes versicolor (PRL 572), encodes a 342-residue mature polypeptide of 36.7 kDa, preceded by a 26-residue signal/propeptide. LPGVI is identified as the gene encoding the 43 kDa lignin peroxidase isozyme LP7 as based on the partial amino acid sequence information available. The polypeptide de
The work presented in this thesis aims at improving spectroscopic techniques for analysis of pharmaceutical solids. This improvement is achieved by the combining and development of instrumentations and data evaluation tools from two research fields: the fields of near infrared spectroscopy and biomedical optics. The thesis include the construction and evaluation of different variable selection te
