Formation of active phases in the Sb-V-, Al-Sb-V-, and Al-Sb-V-W-oxide systems for propane ammoxidation
The Sb-V-O, Al-Sb-V-O and Al-Sb-V-W-O systems were investigated for the ammoxidation of propane to acrylonitrile. Compared with pure approximate to SbVO4, the approximate to SbVO4 that was obtained by co-calcination of pure approximate to SbVO4 with alpha-Sb2O4 at 800 degrees C and subsequent sieving was found to be much more selective to acrylonitrile. XRD data showed no variation of the rutile u

Some physical and nutritional characteristics of genetically modified potatoes varying in amylose/amylopectin ratios
Transgenically modified potatoes with a large spread in amylose/amylopectin ratios were analysed both as tubers and in the form of isolated starch. Different microscopic techniques were used to study starch granules and tuber tissue. Starch gelatinisation properties and recrystallisation of amylopectin and amylose were studied by differential scanning calorimetry. Starch bioavailability and resist
First use of pheromones to detect phenology patterns and density relationships of pine sawflies in German forests
1 Monitoring studies of pine sawflies with pheromone traps were performed for the first time in Germany. Pheromone traps baited with species-specific pheromone substances were installed in pine forests at different locations in Bavaria, Brandenburg and Lower Saxony during two years. 2 It was possible to track the flight phenology of Diprion pini, Gilpinia pallida and Neodiprion sertifer reliably
Studies on patients with a proximal humerus fracture. With special reference to mortality, fragility, morbidity and outcome
Fractures of the proximal part of the humerus occur frequently, especially in elderly women. The present thesis summarizes a series of studies analysing the impact on fracture outcome of factors related both to the fracture itself and to the patient. Fracture type based on comminution and dislocation according to the Neer classification system and epidemiological data involving trauma impact, heal
Growth of one-dimensional nanostructures in MOVPE
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
Gluon distribution functions in the kappa(perpendicular to)-factorization approach
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
Wave-propagation from medical implants -influence of body shape on radiation pattern
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
Service as collaboration: an integrated process in teaching and research. A response to Greenbank
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
Lund University Libraries and the move to Virtua in a networked environment
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
Association between Helicobacter pylori and gastric carcinoma in the city of Malmo, Sweden. A prospective study
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, a misunderstood species in northern Europe
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 kartlagd i Sverige
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
Carotenoid and pheophytin on semiconductor surface: Self-assembly and photoinduced electron transfer
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
User's guide to OSFIC. A computer program for oilspill fires in compartments
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

Wedding Ceremonies in Punjab
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.
