Human cancers are often associated with numerical and structural chromosomal instability. Structural chromosomal aberrations (CAs) in peripheral blood lymphocytes (PBL) arise as consequences of direct DNA damage or due to replication on a damaged DNA template. In both cases, DNA repair is critical and inter-individual differences in its capacity are probably due to corresponding genetic variations
Aerosol trapping has proven challenging and was only recently demonstrated. 1 This was accomplished by utilizing an air chamber designed to have a minimum of turbulence and a laser beam with a minimum of aberration. Individual gold nano-particles with diameters between 80 nm and 200 nm were trapped in air using a 1064 nm laser. The positions visited by the trapped gold nano-particle were quantifie
We used cathodoluminescence imaging to determine diffusion lengths in III-V semiconductor nanowires, grown by metal-organic chemical vapor deposition seeded by gold nanoparticles. Intensity profiles were recorded either from the interface between the substrate and homogeneous nanowires, or from segments in nanowires containing axial heterostructures to determine the diffusion length. We determined
Gate-all-around field-effect transistors are realized with thin, single-crystalline, pure-phase InAs nanowires grown by molecular beam epitaxy. At room temperature, the transistors show a desired high on-state current I-on of similar to 10 mu A arid an on-off current ratio I-on/I-off of as high as 10(6) at sourcedrain bias voltage of 50 mV and gate length of 1 mu m with a gate underlap spacing of
Predictive models used in decision making, such as QSARs in chemical regulation or drug discovery, call for evaluated approaches to quantitatively assess associated uncertainty in predictions. Uncertainty in less reliable predictions may be captured by locally varying predictive errors. In the current study, model-based bootstrapping was combined with analogy reasoning to generate predictive distr
We describe the design of the NanoMAX beamline to be built among the first phase beamlines of the MAX IV facility in Lund, Sweden. NanoMAX will be a hard X-ray imaging beamline providing down to 10 nm in direct spatial resolution, enabling investigations of very small heterogeneous samples exploring methods of diffraction, scattering, absorption, phase contrast and fluorescence. The beamline will
Background: An epidemic of chronic kidney disease of unknown cause has emerged along the Pacific coast of Central America, particularly in relatively young male sugarcane workers. In El Salvador, we examined residence and occupations at different altitudes as surrogate risk factors for heat stress. Study Design: Cross-sectional population-based survey. Setting & Participants: Populations aged
Electronic waste is the fastest growing waste category, seen as a consequence of the industry’s rapid technological advancement. The waste in this industry is problematic due to the inherent heterogenic property of devices, the toxicity of the waste, as well as resource intensive production of the required materials. To decrease this waste and the resource demand in the production of electrical de
Emissions from drained organic soils is a big contributor to global warming and corresponds to 5% of global and 25% of Sweden’s greenhouse gas (GHG) emissions. This study uses a GIS-analysis to map the organic soils in Kristianstad municipality in Sweden and what land use occurs on these soils. The purpose of the study is to provide the municipality with information when investigating the possibi
Packaging waste is an active environmental problem. There is an ongoing process of change in both the EU and Sweden to reduce the amount of packaging waste and create more resources for a circular flow. Considering this, there are contexts, despite new legislation, where single-use packaging will still be offered. Therefore it becomes significant to understand how the consumer can be influenced in
Environmental pollution caused by human activity is one of today's biggest dilemmas. Pollution in air, water and soil can pose risks to human health and the environment and can lead to a reduction in available resources. Investigating and remediating contaminated areas is therefore an important task. In the past 20 years, there have been two major spills of gasoline and diesel at the Energy Po
This paper explores how barriers and risks are perceived by different actors involved in Northvolt's establishment in Skellefteå, Sweden, through the Multi-Level Perspective (MLP) and risk perspective. The study employs a qualitative research design and utilizes document analysis and semi-structured interviews to collect data. The findings contribute to the existing risk framework by introduci
This study aims to investigate the ecological sustainability of different beverage packaging and compare this to consumers’ perception of the most environmentally friendly packaging type. A literature analysis was made to understand the advantages and disadvantages of different packaging as well as consumer behavior from other surveys in other studies. Lastly this study conducted and preformed its
To meet climate objectives our society needs to be more resource efficient, and a circular economy is part of the solution. Maintaining and repairing products to prolong their lifetime is usually better than replacing the product. In Sweden there are existing economic policies such as value added tax and tax reductions that incentivize the consumer towards prolonging the life of their products, bu
Due to the growing e-commerce volumes, product returns have become an increasingly important issue within the fashion industry. About 70 % of all returns are caused by poor fit or size. Therefore, there is a need to improve fit and size information online to decrease the rate of returns. In recent years, there has been an increased interest for implementing AI solutions to improve consumer informa
The Greenhouse Gas Reduction Mandate (GGRM, reduktionsplikten) is Swedish legislation focused on reducing carbon emissions by mandating that the emissions of certain fuels are reduced by a specified percentage, that percentage increasing each year. This paper investigates the rationale behind a political drive to decrease the GGRM, the cost-effectiveness of the GGRM, and the consequences of t
The European union and the Convention on biological diversity require 30% of all land to be protected by 2030, stressing the necessity for increased nature conservation. To meet the requirements different forms of protection are needed. Thus, nature conservation agreements (NCA) relevant for further exploration, as they are not used in as large of an extent as other nature conservation types. Thi
Regulations regarding management of dredged sediment from the maintenance of artificial ponds and other wetlands are ambiguous. Currently in Sweden, compliance with guidelines concerning pollutants is often prioritized over the climate impact associated with the transportation during disposal of these sediments. Therefore, this study aimed to evaluate the applicability of current guidelines to dre
Air pollution is a major environmental and health problem globally, with traffic emissions being a significant source of many pollutants. The aim of this study is to investigate whether the levels of nitrogen dioxide (NO2), ground-level ozone (O3) and coarse particles (PM10) in air changed during the covid-19 pandemic in Sweden, and whether the change varied between urban and rural areas and depen
