BACKGROUND: The contrast medium (CM) dose-to-eGFR (estimated glomerular filtration rate) ratio has recently been advocated to express systemic exposure to CM in assessing the risk of contrast medium-induced nephropathy (CIN). PURPOSE: To evaluate how CIN risk might vary with decreasing eGFR at fixed CM-dose/eGFR ratios and other CIN risk factors, and to find a relatively safe CM-dose/eGFR ratio. M
Gaza has several water problems; limited fresh water supply, inefficient water use by the agricultural sector, high water demand, groundwater contamination, seawater intrusion and shortage of electricity. Water and electricity is the first priority for Gaza that will add significant positive values to the Palestinians living in blocked Gaza and easy operation and maintenance of their ongoing and e
A significant part of the cost of a construction project, up to 90%, consists of purchased goods and services. Suppliers thereby have a large impact on the quality, price and time of projects. Purchasing management is therefore important for the outcome of a project. The aim of research covered by this thesis is to describe and analyse purchasing management and its interrelation with the supplier
Background: Sugarcane is an attractive feedstock for ethanol production, especially if the lignocellulosic fraction can also be treated in second generation (2G) ethanol plants. However, the profitability of 2G ethanol is affected by the processing conditions, operating costs and market prices. This study focuses on the minimum ethanol selling price (MESP) and maximum profitability of ethanol prod
We have investigated the structure of a microbial community in semi-natural sandy grassland in southeast Sweden. The sand is rich in lime, but in most places the soil is decalcified in the upper layers, and therefore this site shows a large variation in pH within short distances. We collected samples at three different soil depths (0-10 cm, 10-20 cm and 20-30 cm) and found the pH to range from 5 t
Two key challenges for governing and managing critical infrastructure risk and resilience are interdependencies between infrastructures and the multi-actor setting in which they operate. This paper looks beyond the Critical Infrastructure (CI) field of research to identify and discuss cross-disciplinary approaches to address these challenges. It explores two related and slightly overlapping resear
The study investigated the effects of forest residue extraction on tree growth and base cations concentrations in soil waterunder different climatic conditions in Sweden. For this purpose, the dynamic model ForSAFE was used to compare theeffects of whole-tree harvesting and stem harvesting on tree biomass and the soil solution over time at 6 different forestsites. The study confirmed the results f
The aim was to describe food intake over time in children and adolescents, with respect to age and gender. The present study was a repeated cross-sectional study using self-reported data from a health questionnaire. Data were collected from the School Health Services in south-east Sweden from 44 297 students, 10, 13-14 and 16 years of age, 48 % girls and 52 % boys from 2009/2010 to 2015/2016. Repo
The purpose of this paper is to provide a review of literature about recruitment, retention and resignation among non-career firefighters. Design/methodology/approach: A systematic review was conducted to identify factors associated with the recruitment, retention and resignation of non-career firefighters. The authors divided the results into three topics and four levels for further analysis. Fin
The Northeast region of Brazil is one of the most susceptible parts of the country to the effects of climate variability leading to severe droughts or extreme floods. Indeed, drought is a major issue due to a large semiarid area that covers 53% of the region, which determines the main climate characteristics of this region. On the other hand, extreme floods have caused widespread damage in river b
BACKGROUND: Triticum aestivum (wheat) is one of the world's oldest crops and has been used for >8000 years as a food crop in North Africa, West Asia and Europe. Today, wheat is one of the most important sources of grain for humans, and is cultivated on greater areas of land than any other crop. As the human population increases and soil salinity becomes more prevalent, there is increased pressure
Natural hazards such as landslides, floods, rockfalls, earthquakes, volcanic eruptions, sinkholes, and snow avalanches represent potential risks to our infrastructures, properties, and lives. That potential will continue to escalate with current and continued human encroachment into risk areas. With the help of geophysical techniques many of those risks can be better understood and quantified, the
The concept of a bioeconomy can be understood as an economy where the basic building blocks for materials, chemicals, and energy are derived from renewable biological resources. Biorefineries are considered an integral part of the development toward a future sustainable bioeconomy. The purpose of this literature review is to synthesize current knowledge about how biorefinery technologies are being
Surface–atmosphere energy exchange is strongly ecosystem-specific. At the same time, as the energy balance constitutes responses of an ecosystem to environmental stressors including precipitation, humidity and solar radiation, it results in feedbacks of potential importance for the regional climate. Northern peatlands represent a diverse class of ecosystems that cover nearly 6 × 106 km2 in the Bor
This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through online media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the divers
Study region: Rukarara River Watershed (RRW), Rwanda. Study focus: DOC leaching has important environmental consequences for both terrestrial and aquatic ecosystems. This paper measures leached dissolved organic carbon (LDOC) and the factors controlling its variation in the RRW, a mixed agriculture and forest watershed in Rwanda. The study describes the relationship of LDOC with land use/land cove
Climate change is a major global threat to biodiversity with widespread impacts on ecological communities. Evidence for beneficial impacts on populations is perceived to be stronger and more plentiful than that for negative impacts, but few studies have investigated this apparent disparity, or how ecological factors affect population responses to climatic change. We examined the strength of the re
Studies on risk factors for penile intraepithelial neo-plasia have been small in size, have not distinguished penile intraepithelial neoplasia from invasive cancer, and have relied on self-reported information. This study investigated risk factors for penile intraepithelial neoplasia in a cohort of 580 penile intraepithelial neoplasia cases and 3,436 controls using information from 7 Swedish regis
In recent years island communities have actively adapted in response to a complex combination of changes that has shaped life on the islands, and this has had gendered consequences. The gender ramifications of adaptation on islands are still largely neglected in adaptation policies, although they are increasingly being addressed in the scientific literature. Understanding gendered consequences is
