Arable land is a valuable natural resource. In Iceland the total size of potential arable land has not been determined but preliminary estimates vary from 420 ha to 15000 ha. These have been based on different definitions of potential arable land and assumptions for minimum continuous land area. In 2010 the Farmers Association of Iceland concluded that there was a need for a standard for evaluatin
Objective To date, the major pathways contributing to cardiovascular disease among night shift workers remain poorly understood. MicroRNAs (miRNAs) have been identified as novel regulators of cardiovascular risk factors and are estimated to control more than 30 candidate miRNAs among night shift workers.Materials and Methods RNA was extracted from plasma samples of 110 night and 90day shift worker
Aim: This study investigated how human activities and local environmental variables shape tree assemblages (species composition in a defined location), comparing their effects on edible and inedible tree species. Three hypotheses were tested: (1) Environmental filtering impacts spatial beta-diversity more than dispersal limitation; (2) human activities significantly influence regional tree beta-di
Populärvetenskaplig sammanfattning: En verksamhet eller åtgärd kan ha stor inverkan på människor, djur, växter, mark, vatten, luft, klimat, landskap och kulturmiljö. För att fatta bästa möjliga beslut om en projekt-ut-formning som tar hänsyn till konsekvenserna för olika berörda miljövärden åter-finns kravet på miljökonsekvensbeskrivning, MKB, i svensk lagstiftning. Syftet med en MKB är att identiAn activity or a measure might have a great impact on people, animals, plants, soil, water, air, climate and landscape. In order to describe the direct and indirect effects an intended activity might have an Environmental Impact Assessment (EIA) must be carried out. This demand is regulated in Swedish legislation and makes it possible to achieve as small impact on the environment as practicable. A
In recent years there has been much attention paid to corporate scandals, and in the Swedish media the Skandia incidents have become a serial as, years after the incidents was revealed, sentences are passed on those involved in the scandal. The former president and vice president of the joint-stock company Skandia were both prosecuted for the economic crime gross breach of faith committed by an ag
During the Salvadoran armed conflict (1980-1992) hundreds of children became separated from their families. The majority of the children were abducted by the armed forces of the government and still to this day the fate and whereabouts of most children are unknown. These children are the ''disappeared children of El Salvador''. In 1994, families of the disappeared children formed a
Skogsskador och skogsdöd är ett växande problem i Europa. "Svarta Triangeln", som ligger i bergsområdet där Tysklands, Tjeckiens och Polens gränser möts, är en av de värst drabbade områdena. I dagsläget saknas kunskap för att kunna förklara skogsskadorna helt och hållet, men markförsurningen i området, som orsakas främst av förbränning av svavelrikt kol i de många kolkraftverken, är trolForest decline is an increasing problem in Europe. "The Black Triangle" area, situated in the mountainous region where the borders of Germany, the Czech Republic and Poland meet, is one of the worst damaged areas. The reasons for the forest dieback are not fully understood, but the soil acidification caused by the burning of sulphur rich coal in the region is considered a major cause. To

(ii) The radicals (O(1D) and OH) were produced by photolysis of ozone molecules with UV-C light. The oxidation process was monitored by a
Handeln var den främsta orsaken till utvecklingen av godstransporter till sjöss. I samband med teknikens utveckling, ökade mängden transporterat gods. Tidigt i handelns historia seglade ägarna till godset med sina varor till destinationsorten. Denna sedvänja blev omöjlig att fortsätta tillämpa, eftersom tekniken utvecklades och det blev möjligt för skepp att segla fler och längre resor. Det lönadeTrade was the main reason for the development of transportation of goods by sea. With the evolution of technology, the amount of goods transported increased. Early in the history of trade, traders would sail with their goods to the port of destination. As the technology allowed more frequent and longer trips, this practice was seen to be impossible to continue. Thus, the bill of lading was invente
Populärvetenskaplig sammanfattning: De kvartära landskapsformerna i södra Sverige skapades till stor del under och i samband med avsmältningen av den senaste inlandesisen. Skåne blev isfritt för ca 13 000 år sedan med en isavsmältning i nordvästar Skåne mot NO. I samband med denna avsmältning skapades ett småkuperat moränlandskap, plana slätter, mindre kullar och åsar. Åsarna har bildats av materiThe purpose with this study is to identify and examine heterogeneities within the ground, which is important for the groundwater flow on a more local scale. Investigation of the geology within an area is normally done through observations in field, combined with studies of geological maps and documented drillings. Depending on drilling methods, varying results are obtained but often with a good re
Under vissa typer av operationer, till exempel då kärlen kring hjärtat opereras, använder sig läkare av en speciell typ av röntgenmaskin för att orientera sig inuti kroppen, så kallad genomlysning. För att undgå att öppna upp bröstkorgen på patienten går läkarna in med små verktyg i kärlen via ljumskarna och upp till hjärtat. Eftersom läkarna står så nära patienten träffar en del av strålningen de

This paper provides a presentation of the rule of law in the EU with regard to the Stability and Growth Pact. As there are different jurisprudential conceptions as to define law, the meaning of the rule of law is inexact. The concept is however generally understood to be an antithesis to the rule of men, which implies arbitrariness. The Stability and Growth Pact is a legal instrument, adopted in a
Abstract Purpose: The main purpose with this thesis was to describe the complexities involved when public sector organizations initiate changes in their organizational culture. This research also aims to depict how managers in a public organization interpret the implementation of two separate “shared value systems”, that originates from different parts of the organization. Research design: This th
Background: Unambiguous interpretation of ordered rating scale response categories requires distinct meanings of category labels. Also, summation of item responses into total scores assumes equal intervals between categories. While studies have identified problems with rating scale response category functioning there is a paucity of empirical studies regarding how respondents interpret response ca
Background: Certain immune-mediated diseases (IMDs) have been associated with increased risk for cardiovascular disorders. The aim of the present study was to examine whether there is an association between 32 different IMDs and first hospitalization for ischemic or hemorrhagic stroke. Methods: All individuals in Sweden hospitalized with a main diagnosis of IMD (without previous or coexisting stro

Two levels of ambient light we
Background: The social environment in which children grow up is closely associated with their health. The aim of this study was to investigate the relationship between maternal educational level, parental preventive behavior, parental risk behavior, social support, and use of medical care in small children in Malmo, Sweden. We also wanted to investigate whether potential differences in child medic
Overwash is the flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. Overwash may cause deposition of sand on and landward of the beach crest, large fan shaped deposits on back ba
Popular Abstract in Swedish Det diagnostiska värdet av röntgen- och nuklearmedicinska undersökningar kan knappast över¬skattas. Däremot innebär undersökningar som baseras på joniserande strålning en liten risk för patienten att senare i livet utveckla en cancer. Därför är det vår skyldighet att hålla stråldoserna så låga som möjligt med bibehållen diagnostisk noggrannhet. Idag utgör medicinska undThe significant increase in the use of CT, alone or combined with SPECT or PET, has raised concerns about patient radiation exposure and the consequent increased risk of malignancy later in life. The overall objective of this work was to evaluate and optimise different approaches for minimising patient radiation absorbed dose and maintaining or improving image quality in CT, SPECT/CT, and PET/CT.
