The vertical positions of four dinoflagellate species in three 48 h periods in late summer in a Swedish fjord (the Gullmar Fjord) reflect changes to the depth of the halocline. During stable, stratified conditions, the chlorophyll a maximum exhibited a diurnal migration pattern, which was disrupted when the halocline was forced closer to the surface by the inflow of more saline water. While condit

Immune system is highly integrated with the nervous and endocrine systems, which is thought to result in covariation between behavioural syndromes and stress- and immune-associated diseases. Very little is known about the associations between behaviour and immune traits in wild animals. Here we describe such an association in passerine birds, the greenfinches (Carduelis chloris). When wild-caught

In situ synchrotron powder X-ray diffraction (PXRD) measurements have been conducted to follow the nucleation and growth of crystalline CexZr1-xO2 nanoparticles synthesized in supercritical water with a full substitution variation (x = 0, 0.2, 0.5, 0.8, and 1.0). Direction-dependent growth curves are determined and described using reaction kinetic models. A disctinct change in growth kinetics is o

Objectives: To estimate intra- and inter-observer reproducibility and reliability of assessment of the color content in adnexal masses at color/power Doppler ultrasound examination for observers with different levels of experience, and to determine if they change after a consensus meeting. Methods: Digital clips with color/power Doppler information of 103 adnexal masses were evaluated independentl

There has been little development regarding analysis of polonium (Po) in environmental samples since the 1960ies. This is due to the straightforward spontaneous deposition of this element on silver (Ag), nickel (Ni) or copper (Cu) without any radiochemical separation. For many years, no radiochemical yield determinant was used and it was generally supposed that the yield was 100% after two deposit

The probability of, and time to, fixation of a mutation in a population has traditionally been studied by the classic Wright-Fisher model where population size is constant. Recent theoretical expansions have covered fluctuating populations in various ways but have not incorporated models of how the environment fluctuates in combination with different levels of density-compensation affecting fecund

Objectives To determine the frequency and nature of erroneous transfer of medication information (medication errors) upon admission to hospital and to study the effect of medication reconciliation. Methods Included patients were 65years of age or older, were living in nursing homes or in their own home with care provided by the community nursing system and had been admitted to hospital. The patien

PURPOSE: To identify factors associated with arthroscopically diagnosed scaphoid fracture displacement and instability. METHODS: This was a secondary use of data from 2 prospective cohort studies. The studies included 58 consecutive adult patients with a scaphoid fracture who elected arthroscopy-assisted operative fracture treatment: some for displacement, some as part of a prospective protoco

A number of different intervention programmes have been described in the literature for caregivers of people with dementia, but the nature of intervention has varied widely. The aim of the present study was to evaluate the efficacy of psychosocial intervention on family caregiver's level of burden and satisfaction, and possible influence of the caregiver's relationship and health and the patient's

OBJECTIVE: To study the prevalence and risk factors for vertebral fractures (VF) in ankylosing spondylitis (AS) and the relation between VF, measures of disease activity, and bone mineral density (BMD) in different measurement sites. METHODS: Patients with AS (modified New York criteria) underwent examination, answered questionnaires, and gave blood samples. Lateral spine radiographs were scor

Wood is a hygroscopic material; always striving to reach equilibrium with the surrounding air, and consequently the moisture content is different in different climate conditions. The strength of wood is directly dependent on the moisture content, lower moisture content leads to increasing strength. Generally, state moisture equilibrium is seldom obtained because the moisture transport in wood is v

A 2-step 'semi-nested' enterovirus PCR was developed and applied to CSF and serum specimens from 27 consecutive patients with aseptic meningitis. CSF and sera from 8 patients with non-enteroviral diagnoses were included as negative clinical controls. Enterovirus RNA was detected in CSF by PCR in 15 of the patients with aseptic meningitis, compared with 6 by virus culture. Acute-phase sera proved p

Objective. This study compares laparoscopic and percutaneous endoscopic gastrostomy (PEG) in a paediatric population to test the hypothesis that there is a difference in the frequency of serious gastrointestinal complications between the two methods. Methods. All reports published between 1995 and 2009 on laparoscopic gastrostomy and PEG in children was included. Prospective and retrospective tria

One third of the earth´s soils is calcareous. Calcifuge plants are excluded from these soils, and one of the main causes is Fe deficiency, as Fe solubility in calcareous soil is very low. A lack of Fe lowers chlorophyll content, visible as yellowing of leaves, called chlorosis. It is demonstrated that the main cause of chlorosis in calcifuges is that a large part of the Fe in their leaf tissues i

Popular Abstract in Swedish Kostfiber kallas de kolhydrater från växtriket som inte bryts ner under matsmältningen och därför når tjocktarmen i stort sett opåverkade. Kostfiber finns till exempel i våra fyra sädesslag, havre, råg, korn och vete, vilka alla är cerealier. Framför allt är det de yttre delarna av cerealiekärnorna, klidelen, som innehåller mycket kostfiber. I cerealier är de vanligasteIt is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. Two types of meat products, frankfurter-type sausages and meatballs have been evaluated in this thesis. In th

As a reaction to our current fast living and increasingly individualistic society, the focus on presence and need for human interaction is rising. With inspiration from Marina Abramovic’s performance work “The artist is present” at MoMa in New York, this project has been focusing on how to create a setting which enhances the interaction between two people. During this project, the aspect of inter

Defective logic on Furutorpsgatan - An identification of present problems and proposed measures Helsingborg City is in the progress to make new maintenance measures on Furutorpsgatan. In relation to that, improvements to the streetscape, is also planned. Therefore a description on which problems that occurs with the current design of Furutorpsgatan, and possible measures to improve the situation h

Signal is a very important part of the railway. If you place a signal or a different object which is also important in the wrong place, can mean increased safety risks. To ease the work of the consultants in the creation of operational site drawings, the aim is to develop an action plan for the creation of a database, which in turn will be used to create a tool that can be used to automate the pro
