A farm systems mass-balance calculation model, FARMFLOW, was applied to a case study comparing organic and conventional management of a Swedish experimental dairy farm, Ojebyn. Parameterisation of the model is implemented using detailed field data from the Ojebyn farm where the two management systems have been run parallel for more than 11 years. Simulations were made to compare the stocks, flows
The aim of this study was to explore older patients' experiences of participation in the prescription process of mobility devices. The study was conducted in two Swedish municipalities and was a qualitative study, based on the focus group interview methodology of Merton et al (1990). In order to recruit a sample fulfilling both homogeneity and heterogeneity criteria, occupational therapists and p
In this study, we describe the expression and function of CD40, a TNF receptor family member, in cervical carcinomas. CD40 was present at very low levels in normal cervical epithelium but was overexpressed in human papillomavirus-infected lesions and advanced squamous carcinomas of the cervix. The stimulation of CD40-positive cervical carcinoma cell lines with soluble CD40L (CD154) resulted in act
Fuel cells in combination with hydrogen are expected to play an important role in a future, sustainable transport system. Recent studies have provided insight into how technological transitions may come about and may be I managed. However, there is a lack of methodologies aimed at starting off transitions or system innovations, in practice. This paper addresses this issue by presenting a methodolo
We have reviewed 184 patients after repair of primary hypospadias. They were operated on and followed-up according to a standard protocol, and the senior author (HS) participated in all operations. The patients were reconstructed using a Byars two-stage procedure ( n = 102) or a Scuderi ( n = 29) or Mathieu ( n = 41) single-stage procedure. The rest ( n = 12) just had a removal of the chordee with
Genetic and phenotypic variation in female response towards male mating attempts has been found in several laboratory studies, demonstrating sexually antagonistic co-evolution driven by mating costs on female fitness. Theoretical models suggest that the type and degree of genetic variation in female resistance could affect the evolutionary outcome of sexually antagonistic mating interactions, resu
Introduction: Transnationalism and migration Ulf Johansson Dahre The 5th annual Somalia International Rehabilitation Centre (SIRC) Conference of the Horn of Africa focused on “The Role of Diasporas in Peace, Democracy and Development”. The conference was held in Lund, Sweden, August 19-20, 2006. The content of this volume reflects some of the views and proceedings presented at the conference. I
Homogeneous charge compression ignition (HCCI) is a hybrid of the sparkignition and compression ignition engine concepts. As in a sparkignition engine, a homogeneous fuel-air mixture is created in theinlet system. During the compression stroke the temperature of themixture increases and reaches the point of auto ignition, just as in acompression ignition engine (or Diesel). One challenge with HCCI
Background and purpose: To evaluate the efficacy and safety of boron neutron capture therapy (BNCT) for glioblastoma multiforme (GBM) using a novel protocol for the boronophenylalanine-fructose (BPA-F) infusion. Patient and methods: This phase II study included 30 patients, 26-69 years old, with a good performance status of which 27 have undergone debulking surgery. BPA-F (900 mg BPA/kg body weigh
Change of HIV-1 coreceptor use has been connected to progression of disease in children infected with HIV-1, presumably subtype B. It has not been possible to discern whether the appearance of new viral phenotypes precedes disease development or comes as a consequence of it. We studied the evolution of coreceptor use in HIV-1 isolates from 24 vertically infected children. Their clinical, virologic
Popular Abstract in Swedish Huntingtons sjukdom (HS) är en ärftlig sjukdom som i första hand drabbar hjärnan. De områden som främst angrips är hjärnbarken, där till exempel människans kognitiva förmågor, personlighet och planeringsförmåga finns samt ett område inne i hjärnvävnaden som kallas striatum, där våra rörelser kontrolleras och korrigeras. Sjukdomen visar sig initialt oftast med diffusa syHuntington's disease (HD) is a neurodegenerative disease caused by a CAG-triplet expansion in the gene encoding the protein huntingtin. The disease typically starts in mid-life and progresses for 15-20 years. To date no effective treatment is available for curing the disease. HD primarily affects the striatum, cerebral cortex and hypothalamus. At later stages cell death is evident in the striatum
More knowledge concerning the association between physical activity and objectively measured attributes of the built environment is needed. Previous studies on the association between objectively measured neighborhood walkability, physical activity, and walking have been conducted in the U.S. or Australia and research findings are available from only one country in Europe - Belgium. The first aim
Insect pollinators are declining globally, partly due to agricultural intensification, which threatens biodiversity and ecosystem services. To help decision-makers make informed choices, a variety of tools such as softwares, websites and frameworks have been developed to guide pollinator-friendly management and conservation. However, the lack of a comprehensive overview of these tools limits stake
The research evaluated retrofitting options for a threestory church community building in Grevie, Sweden, assessing the impacts on energy efficiency, life cycle cost, and environmental concerns. An energy model was generated in IDA ICE to simulate the building performance. Various improvements were tested in two separate retrofit package scenarios. They had the following measures in common: the ad
Micro-society experimental setups are increasingly used to infer aspects of human behavioural evolution. A key part of human society today is our dependence on, and use of, technology–whether simple (such as a knife) or complex (such as the technology that underpins AI). Previously, two groups of researchers used an abstracted-wheel experiment to explore the evolution of human technical behaviour,
This work focuses on the need for modeling and predicting adverse outcomes in immunotoxicology to improve nonclinical assessments of the safety of immunomodulatory therapies. The integrated approach includes, first, the adverse outcome pathway concept established in the toxicology field, and, second, the systems medicine disease map approach for describing molecular mechanisms involved in a partic
