The response of a matrix of 25 lead tungstate (PWO) scintillator detectors, operated at -25 degrees C, to photons in the range 13 MeV-64 MeV has been measured at the tagged-photon facility at MAX-lab, Lund. The tapered PWO crystals, each with a length of 200 mm and a cross-section of 24.4 x 24.4 mm(2) in the front end, read out by 19 mm photomultiplier tubes, were arranged in a 5 x 5 matrix. The r
Staphylococcal enterotoxin D (SED) is one of the most frequently recovered enterotoxins in staphylococcal food poisoning (SFP) outbreaks. The expression and production of SED were investigated in three ham products, i.e. boiled ham, smoked ham and dry-cured Serrano ham incubated at room temperature for seven days. Staphylococcus aureus was also, as a reference, grown in cultivation broth during op
There is increasing interest in the use of arbuscular mycorrhizal fungi (AMF) for ecological restoration, as AMF can improve plant nutrition and growth. However, some AMF can have negative effects on plant growth. It is therefore critical that restoration strategies incorporate appropriate AMF. This research investigated differences in growth and survival of Podocarpus cunninghamii (mountain tōtar
The Branched Chain Saturated Alcohol (BCSA) group of fragrance ingredients was evaluated for safety. In humans, no evidence of skin irritation was found at concentrations of 2-10%. Undiluted, 11 materials evaluated caused moderate to severe eye irritation. As current end product use levels are between 0.001% and 1.7%, eye irritation is not a concern. The materials have no or low sensitizing potent
In photonuclear experiments precise location of the photon beam relative to the experimental sample is critical. Previously used techniques such as using photographic film to identify the position, intensity and centroid of the beam is time-consuming and a faster method is required. PILATUS is a single-photon-counting pixel detector developed at the Paul Scherrer Institute (PSI), Switzerland. It i
PRUNE1 is linked to a wide range of neurodevelopmental and neurodegenerative phenotypes. Multiple pathogenic missense and stop-gain PRUNE1 variants were identified in its DHH and DHHA2 phosphodiesterase domains. Conversely, a single splice alteration was previously reported. We investigated five patients from two unrelated consanguineous Sudanese families with an inherited severe neurodevelopmenta
This Masters' thesis is a study on the information behaviour of hospital personnel at the University Hospital in Lund, Sweden. A questionnaire was distributed to 301 nurses and physicians working in the intensive care unit, the population was reduced to 244 persons. The response rate was 52%, i.e. 125 questionnaires were completed. Nurses constituted 68 % of the population. The survey focuses
Latest research confirmed that plant matter can also produce a non negligible amount of the greenhouse gas methane under aerobic conditions. These findings have led to discussions and controversy within the research community. While KEPPLER ET AL. (2006) as one of the first researchers published results supporting this hypothesis others like DUECK ET AL. (2007) refuted these results within their e
As foreign aid money is continually spent in developing countries, it is incumbent that international aid organizations work towards improving the effectiveness of their projects. In the setting and context of disaster risk reduction and disaster recovery projects, this thesis aims to understand how foreign aid organizations can make Honduran communities less dependent on foreign aid through speci
Author: Simon Sandberg Title: From each according to his abilities, to each according to his needs. Supervisor: Yoshiko Boregren Matsui Reports show that there is an increasing demand for social activity from the elders in elderly care and that people with learning disabilities are being discriminated from the open labour market. To meet the staff requirements of the elderly care year 2030 one o
De förödande konsekvenserna för ekosystemen i samband med nedslaget av en asteroid för 65 miljoner år sedan, i det som idag är Yucatanhalvön, Mexiko, kan spåras i lagerföljderna över hela världen. En hög upplösningsundersökning över krita-paleogen gränsen har utförts i två marina sekvenser - Stevns Klint och Kjølby Gaard, Dammark. Sedimenten analyserades med palynofaciesanalys, Mössbauerspektrosko
Populärvetenskaplig sammanfattning: Undersökningen baseras på prover ifrån borrkärnor som tagits från sandstenar vilka avsattes för ca 200 miljoner år sedan. Vid denna tid var hela nordvästra delen av Skåne täckt av ett stort delta med en avsättningsmiljö som gav sandstenar med ett stort innehåll av ler. Ler deponerades då det rådde lugna vattenmiljöförhållanden, såsom vid olika årstidsvariationerAn examination of permeability differences was made on plugs obtained from six drill cores in both horizontal and vertical directions, representing different facies of the Hettangian strata from the Höganäs Formation. The permeability analyses distinguish permeability differences from anisotropy and an index was created to evaluate the anisotropy. The cause of the measured anisotropy in this study
Objective. To study the effect of an educationally oriented intervention programme, with the recommendations from the National Board of Health and Welfare as a base. Design. A prospective intervention study. Setting. Six day-care centres in Vaxjo, Sweden. Three centres comprised the intervention group and three constituted the control group. Subjects and main outcome measures. The parents and pers
Incomplete taxon sampling has been a major problem in resolving the early divergences in birds. Five new mitochondrial genomes are reported here (brush-turkey, lyrebird, suboscine flycatcher, turkey vulture, and a gull) and three break up long branches that tended to attract the distant reptilian outgroup. These long branches were to galliforms, and to oscine and suboscine passeriformes. Breaking
This study was aimed at increasing our understanding of environmental and parental factors influencing mode choice for children's journeys to organized leisure activities. Three hundred and fifty-seven Swedish parents of 8-11-year-old children completed a questionnaire and kept a travel diary. The design of urban environment, in which the families lived, was assessed by a group of five experts. By
Measurements are presented from proton-proton collisions at centre-of-mass energies of root s = 0.9, 2.36 and 7 TeV recorded with the ATLAS detector at the LHC. Events were collected using a single-arm minimum-bias trigger. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity and the relationship between the mean transverse momentum and charged-particle multi
The paper's target is the historically influential betting interpretation of subjective probabilities due to Ramsey and de Finetti. While there are several classical and well-known objections to this interpretation, the paper focuses on just one fundamental problem: There is a sense in which degrees of belief cannot be interpreted as betting rates. The reasons differ in different cases, but there'
This paper concerns mathematical modeling and computational fluid dynamics of back-shocking during hollow fibre ultrafiltration of dextran T500. In this paper we present a mathematical model based on first Principles, i.e., solving the Navier-Stokes equation along with the continuity equation for both the solute and the solvent. We investigate the validity of the estimate On the optimal back-shock
We present a set of spectrally and temporally resolved clinical fluorescence data-with two separate excitation wavelengths-that was recorded in vivo. We demonstrate that data in the spectral and temporal domains are in certain ways coupled and provide a method for integrated and effective parameterization of spectrally and temporally resolved fluorescence (i.e., time-resolved emission spectra). Th
CCR5-using (R5) human immunodeficiency virus type 1 (HIV-1) strains cause CD4+ T-cell loss in most infected individuals, but mechanisms underlying cytopathicity of R5 viruses are poorly understood. We investigated mechanisms contributing to R5 envelope glycoprotein (Env)-mediated cellular apoptosis by constructing a panel of retroviral vectors engineered to co-express GFP and R5 Envs derived from
