The importance of different additional simplifications used when moving from single site applications to regional applications of the SAFE and MAKEDEP models was studied. The SAFE model is a dynamic soil chemistry model, which apart from physical and chemical soil parameters also needs the historic evolution of atmospheric deposition and nutrient uptake to simulate the effects of acidic deposition
Popular Abstract in Swedish Östeuropeisk industri är ökänd både för sin miljöpåverkan och för sin besvärliga ekonomiska sits. Detta gör att resurserna som finns tillgängliga för miljöarbete är små - om dom finns överhuvudtaget. Den möjlighet som då återstår ligger i den förebyggande miljöskyddsstrategin där förbättringarna uppnås genom att gå in i produktionsprocesserna och effektivisera användninSince 1991 cleaner production projects have been pursued by the donors in Eastern European industry. These projects have aimed at demonstrating the benefits of a preventive approach to environmental protection, and to train people within the industry to perform the cleaner production assessments that constitute the core element of the preventive approach. The large merit of the preventive approach
Free radicals have recently been proposed to play a role in the development of diabetic retinopathy. Ischaemia and hyperglycaemia followed by recirculation have been suggested to initiate free radical production in other tissues and the aim of the present study was to examine whether this could also be the case in the retina. The present study showed retinal cell damage, as measured by pycnotic ce
The diversity of viral strategies to modulate complement activation indicates that this component of the immune system has significant antiviral potential. One example is the Kaposi's sarcoma-associated herpesvirus (KSHV) complement control protein (KCP), which inhibits progression of the complement cascade. Rhesus rhadinovirus (RRV), like KSHV, is a member of the subfamily Gammaherpesvirinae and
The coronary arteries of the isolated rabbit heart were perfused with different contrast media (CM). The effects on cardiac contractile force (CF) from enriching iohexol solutions with sodium, calcium, potassium, magnesium and oxygen were investigated. The effects were studied during normal and reduced perfusion pressure; the latter was intended to simulate flow conditions distal to proximal steno
The influence of personality factors on the appraisal of subjective quality of life in individuals with schizophrenia or schizoaffective disorder is not much investigated. The present study examined this relationship in a sample of 104 patients living in the community. The temperament and character inventory was used to assess personality and the Lancashire quality of life profile was used to asse
Purpose: We evaluated the significance of focal prostate cancer found in sextant biopsies in men participating in a biennial prostate specific antigen (PSA) based screening program. Materials and Methods: In 1995, 10,000 men 50 to 65 years old were randomized to biennial screening with PSA testing. Sextant biopsies were recommended when total PSA was 3 ng/ml or greater at screening rounds 1 and 2,
The purpose of this review is to present what is known about capillary phenomena in wood and discuss how it should be measured and modelled.
This article deals with the construction of femininity among female football players. The issue focuses on how girls, competing in a typically male sports, talk about and look upon themselves. The data has been derived from participant observations of a Swedish female football team, as well as from open-ended interviews with seven of the players, between 15 and 18 years old. The following aspects
This paper analyses the nature and scale of transaction costs (TCs) borne by obliged parties under a "Tradable White Certificate" (TWC) scheme. Taking the first phase of the Energy Efficiency Commitment (EECl) in Great Britain as a case study, several sources of TCs were considered, such as search for information, persuasion of customers, negotiation with business partners, and measurement and ver
Gypsum calcination in superheated steam is investigated. It is shown that superheated steam positively influences the formation of hemihydrate and avoids formation of anhydrite. By measuring the specific surface area the products are shown mainly to consist of alpha-hemihydrate. By recovering the heat of vaporization a specific energy use of 379 kJ/kg dihydrate can be obtained. This is substantial
Thirty-two Norway spruce [Picea abies (L.) Karst.] and Scots pine (Pinus sylvestris L.) stands in southern Sweden were studied for a period of 12 years to evaluate acidification-induced chemical changes in the soil. Soil, at 20-30 cm depth in the mineral layer, was sampled three times during this period (1988, 1993 and 1999). The results show that pH(BaCl2) in mineral soil decreased by, on average
