Russia has become a magnet for migrant workers from other post-Soviet countries, especially Central Asians. Although Russian business elites generally welcome this cheap labor source, the government has deferred to, and at times encouraged, xenophobic popular sentiment. Steadily tightening immigration rules have forced many foreign workers into the informal economy, where they are vulnerable to ex
Digital twins, which are a new concept in industrial control systems (ICS), play a key role in realizing the vision of a smart factory, and they can have different effective use cases. With digital twins, we have virtual replicas of physical systems so that they precisely mirror the internal behavior of the physical systems. Hence, synchronization is necessary to keep the states of digital twins i
Chip based bio/chemical analysis relies on networks of fluidic channels that are connected to reaction chambers and sensors. For sensitive detection it is important to scale down the size of the channels so that they approach the relevant length scales of the molecules of interest. Here we have made sealed channels on the 100 nm scale using nanoimprinting to pattern the sacrificial polymer polynor
We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus bridges a large part of the existing gap between heavy ion and high energy physics phenomenology. The model is inspired by the old Fritiof model and the notion of wounded nucleons. Two essenti
It is widely known that diesel combustion in a compression ignition (CI) engine produces and emits a significant amount of particulate matter (PM) which contributes to degradation in both health and environment. The origin of the soot formation depends on several factors, however, the main source of the soot emissions is the combustion of the diesel fuel itself. To circumvent this issue, studies hIt is widely known that diesel combustion in a compression ignition (CI) engine produces and emits a significant amount of particulate matter (PM) which contributes to degradation in both health and environment.

Purpose: The aim of the study is to investigate associations between socioeconomic and occupational factors and lymphoproliferative (LP) diseases. Methods: We performed a follow-up study on the economically active Swedish population, based on the Swedish Family-Cancer Database. Standardized incidence ratios and 95% confidence intervals were calculated in different social classes and occupations. R
Water resources face risks due to water use stress and water scarcity. Collective and integrated actions by different institutions and stakeholders are needed to reduce future water risks. This paper aimed to assess the potential for a water stewardship partnership in River Nzoia Basin to reduce future water risks facing the ecosystem, agriculture, and other sectors by quantifying water risks and
Photovoltaics is amongst the most important technologies for renewable energy sources, and plays a key role in the development of a society with a smaller environmental footprint. Key parameters for solar cells are their energy conversion efficiency, their operating lifetime, and the cost of the energy obtained from a photovoltaic system compared to other sources. The optimization of these aspects
IEEE 1687 enables flexible access to on-chip instruments via dynamically reconfigurable networks. Reconfiguration allows reducing instrument access time by keeping only those instruments on the scan-path which are required for each access. To perform reconfiguration and execute commands described in instrument access procedures, scan vectors are generated in a process called retargeting. These vec
A schematic mechanistic box model presenting processes in atmospheric chemical cycles is used to present the main research objectives. From this the main use of PIXE within atmospheric chemistry is discussed. An analytic system giving molecular composition is necessary to fully understand and quantify the chemical and physical pathways described in the model for different compounds. Combining PIXE
Large carnivore conservation in the Swedish multi-use landscapes can only be successful if carnivores can share the landscape with human activities. Interventions to reduce the risk of brown bear, lynx, wolf, and wolverine attacks on domestic animals have become a core element in carnivore management. Whereas the intention is that interventions mitigate human-carnivore interactions, the interventi
Protein self-association may be detrimental in biological systems, but can be utilized in a controlled fashion for protein crystallization. It is hence of considerable interest to understand how factors like solution conditions prevent or promote aggregation. Here we present a computational model describing interactions between protein molecules in solution. The calculations are based on a molecul
Highly glazed buildings are designed by architects to be airy, light and transparent with more access to daylight. Their energy efficiency, however, has become questioned. Therefore, energy simulations of single skin office buildings in Sweden were carried out, using a dynamic energy simulation tool. In order to study the impact of glass on the energy use during the occupation stage, office buildi
Biomass provides the largest reduction of carbon dioxide (CO2) emission when it replaces coal, which is the dominating fuel in heat and electricity production in Poland. One means of replacing coal with biomass is to co-fire biofuels in an existing coal-fired boiler. This paper presents an analysis of the strengths and weaknesses of co-firing biofuels in Poland with respect to technical, environme
As a second major result we show how to combine the path cover technique with LCA solutions for dags with small depth [9]. Our algorithm attains the best known upper time bound for this problem of O(n 2.575). However, most notably, the algorithm performs better on a vast amount of input dags, i.e. dags that do not have an almost linear-sized subdag of extremely regular structure. Finally, we appl
Fluorescence microscopy is introduced as a low cost quality control process for nanoimprint lithography. To depict imprinted structures down to 1 mum lateral size and to detect residues down to 100 nm lateral size, the standard printable polymer mr-18000 is labelled with less than 0.1 wt.% fluorescent dye. Three different types of stamps are used to determine the dependence of the shape and size o
