The use of metal organic vapor-phase epitaxy (MOVPE) for growth of one-dimensional nanostructures in the material systems GaAs, GaP, InAs and InP is investigated. Some kinetic effects are discussed, especially the general finding that in MOVPE thinner whiskers grow faster than thicker whiskers. Effects of growth temperature on growth rate and shape of the whiskers, the effects of different growth
At small x, the effects of finite transverse momenta of partons inside a hadron become increasingly important, especially in analyses of jets and heavy-quark production. These effects can be systematically accounted for in a formalism based on k(perpendicular to)-factorization and unintegrated distribution functions. We present results for the integrated and unintegrated distribution functions obt
The influence of a patient's body shape and position on the radiation pattern from an implanted radio transmitter has been simulated. Simulations and comparisons have been made with different body shapes (male, female and child) and different arm positions. It can be concluded from the results that the difference between different body shapes are at least as large as the influence of a patients ar
This article is a response to Greenbank's (2006) The academic's role: the need for a re-evaluation? It is also a contribution to the ongoing debate about the need to develop a broader view of scholarship and the different activities related to it such as 'teaching', 'research' and 'service to the community'. Arguments related to current research are presented to enhance a deeper understanding and
The reason for moving from one library system to another or from one generation of a library system to the next must be to improve the library's ability to serve its users in a better and more effective way. An integrated library system, today, is very complex and multi-moduled, which makes it difficult to distinguish one system from another. The article describes the long and bumpy road from the
BACKGROUND: We have investigated the association between Helicobacter pylori and gastric carcinoma through a nested case-control study in a single city. METHODS: From a cohort of 32,906 residents recruited from 1974 through 1992, 56 cases of gastric adenocarcinoma and 224 matched controls were selected. The mean interval between serum collection and diagnosis was 5.7 years. Frozen serum or plasma
Caloplaca fuscorufa H. Magn. is a poorly known species that for a long time was known only from a single locality in Jämtland, northern Sweden, where it was collected in 1910. It has been suggested to be synonymous with C. crenularia (With.) J. R. Laundon, but has also been confused with C. exsecuta (Nyl.) Dalla Torre & Sarnth. We have compared the isotype of C. fuscorufa and material collecte
Ataxia-telangiectasia (AT) is a rare autosomal recessive disease with a complex phenotype involving cerebellar degeneration, immunodeficiency, cancer risk and radiosensitivity. Our aim has been to identify Swedish AT patients in order to study the possible "Swedish phenotype" of the disease. In the 19 patients identified in Sweden we found a phenotype fairly similar to what has been described inte
Self-assembling of a carotenoid and pheophytin a into a supramolecular system was observed on the surface of nanocrystalline TiO2, and the photoinduced electron-transfer reactions within the system were studied by means of femtosecond transient absorption and laser flash photolysis techniques. Excitation of the pheophytin moiety results in ultrafast electron transfer from carotenoid to the excited
This document is a description of the computer code OSFIC. The development of the code was sponsored by the Swedish Nuclear Power Inspectorate as an effort to develop useful tools for fire analyses in nuclear power plants. The name OSFIC stands for "OilSpill Fires In Compartments". The purpose of this paper is to describe the code and to facilitate the use of the computer program. A more detailed

While the specificities of different religious communities are underscored, the paper focuses on the shared cultural values and symbols that frame marriage ceremonies in the Punjab. The study concludes with how ritual theories help us analyse these ceremonies and assess the impact of modernity on their nature and function.

Fetal ECG waveform analysis as an adjunct to electronic fetal monitoring (EFM) has developed over the last 3 decades. From a multitude of potential parameters, ST waveform analysis has been documented to provide the information required to shift EFM from a screening device to a diagnostic tool that meets the standards of evidence-based medicine. This chapter details the experimental and clinical e
Popular Abstract in Swedish Det finns i Sverige idag över 100 000 personer vilka överlevt insjuknande i stroke (blodpropp eller blödning i hjärnan). Varje år inträffar ca 20 000 ? 25 000 nyinsjuknanden och ca 5 000 - 10 000 återinsjuknanden i stroke. Vanliga symtom både vid det akuta insjuknandet, och senare efter genomgången akutsjukvård och rehabilite-ring, är förlamningar, talrubbningar, sväljnThe aims were to follow stroke patients over time with respect to general pain, shoulder pain, weight loss, and health related quality of life (HRQOL), the latter also in stroke survivors' informal caregivers. Methods During a 1 year period, 416 first-ever stroke patients were included in the population based Lund Stroke Register; 327 survivors were followed up after four months and 305 one year
Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. Detailed Nilsson-Strutinsky calculations with the cranked Woods-Saxon potenti
The NMDA receptor complex represents a key molecular element in the pathogenesis of long-term synaptic changes and motor abnormalities in Parkinson's disease (PD). Here we show that NMDA receptor 1 (NR1) subunit and postsynaptic density (PSD)-95 protein levels are selectively reduced in the PSD of dopamine (DA)-denervated striata. These effects are accompanied by an increase in striatal levels of
A fermented, oat-based product with properties resembling those of the traditional, Swedish, fermented milk product "filmjoelk" (sour milk) was developed. Com., mixed-strain, mesophilic starter cultures were grown in the oatbases M30, G40, and Oatly, which differed in the compn. of their carbohydrates. The exopolysaccharide-producer Pediococcus damnosus 2.6 was included to increase the viscosity o
