The valence of the europium dopant and selected rare earth co-dopants (Ce3+, Dy3+, and Yb3+) in the Sr2MgSi2O7:Eu2+,R3+ persistent luminescence materials were studied by room temperature XANES measurements. The results indicated the co-existence of both divalent and trivalent europium in all the studied materials. The relative amount of Eu3+ was observed to increase upon increasing exposure to X-r

Identifying the relative importance of predation and resources in population dynamics has a long tradition in ecology, while interactions between them have been studied less intensively. In order to disentangle the effects of predation by juvenile fish, algal resource availability and their interactive effects on zooplankton population dynamics, we conducted an enclosure experiment where zooplankt

Eutrophication has been one of the largest environmental problems in aquatic ecosystems during the past decades, leading to dense, and often toxic, cyanobacterial blooms. In a way to counteract these problems many lakes have been subject to restoration through biomanipulation. Here we combine 13 years of monitoring data with experimental assessment of grazing efficiency of a naturally occurring zo

This report is a first attempt to use the design perspective we have developed in earlier reports in this series (Brehmer & Tehler, 2013: Tehler & Brehmer, 2013) in practical design of a system that would help Swedish County Administration Boards to meet their area responsibility in cases of major crises and accidents in their counties. The work starts with the development of a design hier

Quality Assurance (QA) is a comprehensive method for evaluation of an accelerator's performance. It involves tools aiming at getting a correct absorbed dose to the patient and a good uptime. Daily, weekly, monthly and yearly checks of an accelerator are needed for a good surveillance of the accelerator. An acceptance test is done to check that the accelerator at delivery is within specified limits

The conference series European Conference on Scientific Publishing in Biomedicine and Medicine (ECSP) was originated at the Faculty of Medicine, Lund University, Sweden and was for the first time launched in Lund in 2006. The mission to be highly relevant for researchers was retained at the second meeting, hosted by University of Oslo, Library of Medicine and Health Sciences. The meeting focused o

På 1980-talet blev ”brukare” ett modeord i offentlig förvaltning och förvaltningsforskning. Termen betecknar den som använder sig av välfärdsservice (jfr. engelskans service user), eller ”slutmottagare” av offentlig nyttighet eller åtgärd. Brukare av välfärdstjänster vet hur hjälp och service fungerar i praktiken och kan därför ge synnerligen viktig återkoppling enligt devisen: ”Den som har skorna

Flow fields and shear-induced structures in the lamellar (L-alpha) phase of the system triethylene glycol mono n-decyl ether (C10E3)/water were investigated by NMR velocimetry, diffusometry, and H-2 NMR spectroscopy. The transformation from multilamellar vesicles (MLVs) to aligned planar lamellae is accompanied by a transient gradient shear banding. A high-shear-rate band of aligned lamellae forms

This article explores construction, production and distribution of environmental information in social media. Specifically, the focus is on people's accounts in social media of their everyday life practices aimed at leading what are considered environmentally friendly lives. The article seeks to establish how through the reproduction of alignments of certain everyday and domestic practices with en

NEW NEURONS ARE CONTINUOUSLY GENERATED IN TWO ADULT BRAIN REGIONS: the subgranular zone of the hippocampus and the subependyma by the lateral ventricles, referred to as the neurogenic niches. During their development from neural stem cells to mature functionally integrated neurons numerous choices are made, such as proliferation or quiescence, cell survival or death, migration or establishment, gr

Pro-inflammatory protein S100A9 was established as a biomarker of dementia progression and compared with others such as Aβ1-42 and tau-proteins. CSF samples from 104 stringently diagnosed individuals divided into five subgroups were analyzed, including nondemented controls, stable mild cognitive impairment (SMCI), mild cognitive impairment due to Alzheimer's disease (MCI-AD), Alzheimer's disease (

Abstract Aim: To compare cognitive ability, school achievement and self-perceived health aspects in adolescents born extremely preterm and term born controls. Method: Fifty-two, out of 61, extremely preterm born adolescents (mean age 18.4 years) and 54 matched controls (mean age 18.3 years) born at full term were investigated; intelligence quotient was measured with the Wechsler Adult Intelligence

Abstract in Romanian I denna artikel gör vi en jämförelse, i historiskt perspektiv, vad gäller rumänska studier på campus och via internet. Vi diskuterar en mycket intressant fråga i detta moderna lärandesystem, i.e ”e-learning”, nämligen lärarens nya roll.

Popular Abstract in Swedish Diabetes mellitus, kronisk njursjukdom samt aterosklerotisk hjärtsjukdom utgör de vanligaste orsakerna till hjärt-kärlsjukdom och för tidig dödlighet. Dessa sjukdomar har blivit ett stort världsomfattande hälsoproblem med ökande prevalens och incidens. Tidig identifiering av patienter som ligger i riskzonen for komplikationer, framförallt hjärt-kärl komplikationer, tordRisk stratification of patients with chronic kidney disease and atherosclerotic heart disease is crucial. Microalbuminuria (MA) is associated with an increased risk of kidney and cardiovascular (CV) death, especially in patients with diabetes. However, MA in many instances is not sensitive for disease outcome; for instance, not all diabetic patients with albuminuria progress to kidney failure, and
