Modulbaserad lakvattenbehandling - en möjlighet att minska soptipparnas påverkan på människa och miljö? Uppemot 8000 gamla övergivna deponier och ett 70-tal aktiva deponier finns i Sverige. Gemensamt för dessa är att de kan ge upphov till ett förorenat lakvatten. Genom tillämpningen av ett modulbaserat reningssystem kan effekterna på människa och miljö begränsas. Modulsystemet har visat sig vara fA change in legislation has resulted in that many of Sweden’s municipal landfills were closed in the beginning of this century. After landfill completion, the oper-ator is responsible for at least 30 years to take action with regard to the protec-tion of human health and the Environment. In contribution Swedish landfill owners are facing increasing demands on local leachate treatment due to a chan

This present study is a qualitative examination of government policy regarding Danish, unemployed and uneducated youths. The empirical basis for the study consists of fieldwork, in the form of participant observation and qualitative interviews. The physical field of study consisted of the municipality of Uddannelsesby. Within the study informants, such as the aforementioned youths, but also munici

Den negativa påverkan på biologisk mångfald från markanvändning får allt större uppmärksamhet. Det akuta behovet av att minska förlusten av biologisk mångfald kräver omfattande metoder för att bedöma påverkan på biologisk mångfald från produkter och tjänster. Livscykelanalys (LCA) är ett verktyg som används för att stödja beslutsfattande, men inkluderingen av påverkan på biologisk mångfald i LCA äThe negative impact on biodiversity from land use is attracting increasing attention. The urgent need to mitigate biodiversity loss calls for comprehensive methods to assess the biodiversity impact of products and services. Life Cycle Assessment (LCA) represents a widely used tool to support decision making, but the inclusion of biodiversity impact in LCA remains under development. This master the

The purpose of current study is to produce groundwater qanat potential map using frequency ratio (FR) and Shannon's entropy (SE) models in the Moghan watershed, Khorasan Razavi Province, Iran. The qanat is basically a horizontal, interconnected series of underground tunnels that accumulate and deliver groundwater from a mountainous source district, along a water- bearing formation (aquifer), and t

As society’s electricity demands increase, technical solutions and advancements are essential to meet energy needs. Solar energy is a promising source, and solar cells enable the conversion of sunlight into electricity. This study is in collaboration with Midsummer AB, a Swedish company that specializes in sustainable solar cells. The company employs a sputtering process for manufacturing these ce

The steel industry in Sweden is responsible for 10% of the annual Swedish CO2 emissions. As a way to abate this sector, H2 Green Steel are establishing a new green steel production site in Boden. Their way of producing steel, through the EAF route and by using hydrogen-reduced DRI will reduce the CO2 emissions by over 90%. Besides iron ore, steel scrap is the most important input raw material for

Questions: (1) Does soil acidification in calcareous sandy grasslands lead to loss of plant diversity? (2) What is the relationship between the soil content of lime and the plant availability of mineral nitrogen (N) and phosphorus (P) in sandy grasslands? Location: Sandy glaciofluvial deposits in south-eastern Sweden covered by xeric sand calcareous grasslands (EU habitat directive 6120). Methods:

Popular Abstract in English The work described in this thesis is in the field of industrial biotechnology, which can be defined as a branch of biotechnology aimed at sustainable production of chemicals, materials and fuels with the help of microorganisms. Microorganisms are very diverse and possess a wide variety of enzymes allowing them to transform inexpensive molecules into valuable ones, or toBaker’s yeast, Saccharomyces cerevisiae’s potential in industrial biotechnology for producing valuable products e.g. biofuels, bulk chemicals, bio-flavours and pharmaceuticals is established. In order to achieve efficient production, the intracellular balance of the NADH/NAD + redox couple must be monitored and maintained, as this influences the feasibility of over 100 reactions in the cell. My ap

Background and purpose: Patients with focal cartilage lesions experience functional impairment. Results for biological treatments in the middle-aged patient is poor. Previous studies with focal prosthetic inlay resurfacing have shown a higher risk of conversion to total knee replacement at mid-term follow-up. A novel customized implant (Episealer, Episurf, Stockholm, Sweden) has been proposed to i

Electroconvulsive therapy (ECT) is effective and safe for adults with severe depression, but less studied in adolescents. Here, we examined the indications, prevalence, practice, response and remission rates, and side effects in young people treated with ECT in Sweden. We also examined the usage of ECT in the transition to adult psychiatry. Using data from national patient registers and the Swedis

Background: Different textile constituents may act as allergens and/or irritants and provoke textile contact dermatitis (TCD). Objectives: To report a case of TCD caused by ethylene glycol monododecyl ether and 2.4-dichlorophenol, present in a bikini. Methods: A woman presented with an eczematous, pruritic rash in the area of the bikini straps and back. Patch testing was performed with the Europea

A wide range of biomass resources provides significant opportunities to meetsociety's needs, such as ensuring food nutritional security, responsible use andconsumption. Seaweed, one of the abundant natural resources along the Swedishcoastline and characterized by rapid growth, has attracted significant interest as asource of biomass for various industries, including food, biochemical, and biofuelp

Introduction: Haemophilia A care has changed with the introduction of emicizumab. Experience on the youngest children is still scarce and clinical practice varies between haemophilia treatment centres. Aim: We aimed to assess the current clinical practice on emicizumab prophylaxis within PedNet, a collaborative research platform for paediatricians treating children with haemophilia. Methods: An el

BACKGROUND: It is controversial whether breast reconstruction with a microvascular free flap should be done without restrictions in patients who have not had radiotherapy. Many regard it as too expensive, but some consider it better and more economically advantageous than an implant reconstruction. METHODS: Databases of publications were searched to find out under what conditions is it suitable to

Predicted responses of transpiration to elevated atmospheric CO2 concentration (eCO2) are highly variable amongst process-based models. To better understand and constrain this variability amongst models, we conducted an intercomparison of 11 ecosystem models applied to data from two forest free-air CO2 enrichment (FACE) experiments at Duke University and Oak Ridge National Laboratory. We analysed

Assessments of terrestrial carbon fluxes require a thorough understanding of links between primary production, soil respiration and carbon loss through drainage. In this study, stem girdling was used to terminate autotrophic soil respiration including rhizosphere respiration and root exudation in a temperate Norway spruce stand. Rates of soil respiration and dissolved organic carbon (DOC) formatio

Regime shifts in shallow lakes are typically characterized by submerged macrophyte (clear water regime) or phytoplankton (turbid regime) dominance. Climate warming is expected to affect water quality and facilitate turbidity in lakes, but we may also expect synergistic effects on organisms' interactions from climate and local specific dynamics in lakes. We here examined long-term changes in phytop

Microchip immobilized enzyme reactors (mu IMERs) with immobilized endoglucanases were applied for the hydrolysis of methyl cellulose (MC). MCs of various molecular weights were hydrolyzed using two mu IMERs containing immobilized celloendoglucanase Cel 5A from Bacillus agaradhaerens (BaCel 5A) connected in series. Hydrolysis by the mu IMER could be confirmed from the average molar masses and molar
