The aim of this study was to assess the level of oxidative stress and DNA damage in subjects occupationally exposed to lead. Material and methods. We studied a population of 78 male workers exposed to lead in a lea

Not even close to the goals - A “snapshot” of Swedish property owners' energy renovation plans

A pre-requisite to reach the EU 2030 and beyond targets is a significantly increased ambition among property owners regarding energy-efficient refurbishments. The Swedish Energy Agency and the National Board of Housing, Building and Planning are on the Swedish government assignment developing a strategy with policy instruments to increase energy-efficiency oriented renovation. In order to design t

The effect of temperature and moisture on lag phase length of bacterial growth in soil after substrate addition

Microorganisms in soil are commonly limited by available substrate, and removing the limitation will increase activity and growth, with predictable dynamics in growth. The initial phase with a lag period (λ) will usually be followed by exponential growth (also called log phase, with growth rate μ). These two growth phases may be differently affected by environmental conditions, like temperature an

Silicon fertilization enhances the resistance of tobacco plants to combined Cd and Pb contamination : Physiological and microbial mechanisms

Remediation of soil contaminated with cadmium (Cd) and lead (Pb) is critical for tobacco production. Silicon (Si) fertilizer can relieve heavy metal stress and promote plant growth, however, it remains unknown whether fertilization with Si can mitigate the effects of Cd and Pb on tobacco growth and alter microbial community composition in polluted soils. Here we assessed the effect of two organic

Adapting for shared use – evaluating the lifecycle carbon impact

Vast amounts of resources extracted through the times are in today’s built environment, with only an estimated 20-30% of building material recycled or reused and the sector accounting for over 35% of the EU’s total waste generation. Buildings are also responsible for 25-40% of all global carbon dioxide emissions. Circular Economy (CE) refers to the better management of resources and waste by closi

Forest water use and water use efficiency at elevated CO2: a model-data intercomparison at two contrasting temperate forest FACE sites

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

Spectral heterogeneity of QuickBird satellite data is related to fine-scale plant species spatial turnover in semi-natural grasslands

Abstract Question: Can satellite data be related to fine-scale species diversity and does the integrated use of field and satellite data provide information that can be used in the estimation of fine-scale species diversity in semi-natural grassland sites? Location: The Baltic Island of Oland (Sweden). Methods: Field work including the on-site description of 62 semi-natural grassland sites (repres

Estimation of daily evapotranspiration over Africa using MODIS/Terra and SEVIRI/MSG data

Most existing remote sensing-based evapotranspiration (ET) algorithms rely exclusively on polar-orbiting satellites with thermal infrared sensors, and therefore the resulting ET values represent only "instantaneous or snapshot" values. However, daily ET is more meaningful and useful in applications. In this study, daily ET estimates are obtained by combining data from the MODIS sensor aboard the p

Evaluating the role of DNAJ chaperones on PolyQ aggregation in PolyQ expressing HEK293 cell lines using CRISPR-dCas9 knock-down

Guardian proteins help or hinder clumpy proteins? Proteins are products encoded by DNA in cells. They need to be folded in a certain structure to perform their function in the cell. Because of this, the proteins need a quality control system to ensure that they are folded correctly. A large group of proteins called as chaperones are important in this regard. The main role of chaperones is to fold

The impact of Digital Inclusive Finance on Green Total Factor Productivity under the conditions of Regional Development, a Chinese case based on a spatial perspective

As a country with a high proportion of population and land area in the world, China is in a stage of changing its economic development direction, from the previous extensive economic growth to the intensive economic growth. At the same time, due to the limited total amount of resources and limited environmental bearing capacity on the earth, certain constraints are found in terms of amount and str

Two hundred years of land-use change in the South Swedish Uplands: comparison of historical map-based estimates with a pollen-based reconstruction using the landscape reconstruction algorithm

Long-term records of environmental history at decadal to millennial time-scales enable an assessment of ecosystem variability and responses to past anthropogenic disturbances and are fundamental for the development of environmental management strategies. This study examines the local variability of land-use history in the South Swedish Uplands over the last 200 years based on pollen records from t

Pollen production estimates (PPEs) and fall speeds for major tree taxa and relevant source areas of pollen (RSAP) in Changbai Mountain, northeastern China

For model-based quantitative reconstructions of past vegetation cover on the scale of landscapes, pollen productivity estimates (PPEs) are key input parameters. In this study, we employed a random sampling strategy to collect moss polsters at 20 sites in Changbai Mountain, northeastern China. A detailed vegetation survey within 1000-m radius around each sampling point was carried out and digitized

Detection of Faint Stars near Gaia Objects

The upcoming ESA space astrometry mission Gaia, planned to be launched in early 2012, has been designed to scan the whole sky (flux limited, corresponding to magnitude 20 in the Gaia passband) during a five-year observational phase. It will measure the astrometric parameters (positions, parallaxes and proper motions) of more than one billion stars, complemented by multi-epoch spectrometric and rad

Omplacering och turordning efter AD 2009 nr 50

Uppsatsen redogör för rättsreglerna kring omplacering och turordning vid arbetsbristuppsägningar. Det finns ett omfattande regelverk kring anställningsskyddet i Sverige. Det reglerar hur arbetsgivare ska uppträda då uppsägningar ska äga rum. Det krävs saklig grund för att en arbetsgivare ska ha rätt att säga upp en arbetstagare. Detta framgår tydligt ur 7§ anställningsskyddslagen. För att sakligThis essay describes the legal rules regarding relocation and order of priority in connection with termination of employment due to redundancy. There are comprehensive regulations on employment protection in Sweden. It regulates how employers should act when the redundancies will take place. It requires grounds for dismissal for an employer to have the right to terminate an employee. This is evid

Temporal Association of Total Serum Cholesterol and Pancreatic Cancer Incidence

Previous studies have suggested a “cholesterol-lowering effect” of preclinical pancreatic cancer, suggesting lower total cholesterol as a potential diagnostic marker. Leveraging repeated measurements of total cholesterol, this study aims to examine the temporal association of total cholesterol and pancreatic cancer incidence. We conducted a nested case-control study based on a Korean National Heal

New satellite-based estimates show significant trends in spring phenology and complex sensitivities to temperature and precipitation at northern European latitudes

Recent climate warming has altered plant phenology at northern European latitudes, but conclusions regarding the spatial patterns of phenological change and relationships with climate are still challenging as quantitative estimates are strongly diverging. To generate consistent estimates of broad-scale spatially continuous spring plant phenology at northern European latitudes (> 50° N) from 2000

Holocene Hydrographic Variations From the Baltic-North Sea Transitional Area (IODP Site M0059)

Deoxygenation affects many continental shelf seas across the world today and results in increasing areas of hypoxia (dissolved oxygen concentration ([O2]) <1.4 ml/L). The Baltic Sea is increasingly affected by deoxygenation. Deoxygenation correlates with other environmental variables such as changing water temperature and salinity and is directly linked to ongoing global climate change. To place t

Staff ratings of occupational engagement among people with severe mental illness- psychometric properties of a screening tool in the day center context

Background: Staff who plan and organize day center activities may need to observe the attendees’ performance and progression. This led us to develop a tool for that purpose, termed General Occupational Engagement in people with Severe mental illness (GOES). The aim was to investigate its psychometric properties in terms of factor structure, internal consistency, corrected item-total correlations (

Dependencies of Four Mechanisms of Secondary Ice Production on Cloud-Top Temperature in a Continental Convective Storm

Various mechanisms of secondary ice production (SIP) cause multiplication of numbers of ice particle, after the onset of primary ice. A measure of SIP is the ice enhancement ratio (“IE ratio”) defined here as the ratio between number concentrations of total ice (excluding homogeneously nucleated ice) and active ice-nucleating particles (INPs). A convective line observed on 11 May 2011 over the Sou
