Textile industries are responsible for one of the major environmental pollution problems in the world, because they release undesirable dye effluents. Textile wastewater contains dyes mixed with various contaminants at a variety of ranges. Therefore, environmental legislation commonly obligates textile factories to treat these effluents before discharge into the receiving watercourses. The treatme

Influence of sintering temperature on both phase composition and structure of ceramic matrix composites based on cubic boron nitride with binders in a form of Al and the Ti, Cr, V carbides are investigated by methods of physical materials science. As the object of study, three cBN–TiC–Al, cBN–Cr3C2–Al, cBN–VC–Al compositions containing 60% vol. cBN are selected. The composites are obtained by high

Cancer stem cell populations are important for the initiation, progression and metastasis of tumors. The mechanisms governing cancer stem cell control are only partially understood, but activation of the Notch3 pathway plays a crucial role in the maintenance of breast cancer stem cells. Expression of Cartilage Oligomeric Matrix Protein (COMP) in breast cancer cells is correlated with poor survival

Multi-cell wireless systems usually encounter both intra-cell and inter-cell interference, which can be mitigated via coordinated multipoint (CoMP) transmission. Previous works on multi-cell analysis in the microwave band generally consider fully digital beamforming, requiring a complete radio-frequency chain behind each antenna. This is practically infeasible for millimeter-wave (mmWave) systems

Lens–based massive multiple–input multiple–output (MIMO) systems have considerable potential to reduce signal processing cost at millimeter–wave frequencies. As a result, they are able to lower the effective channel dimension via beam selection, realized with a network of radio–frequency (RF) switches. However, lens arrays suffer from the inherent quantization of the beamspace, as well as errors d

Overexpression of recombinant proteins in bacteria may lead to their aggregation and deposition in inclusion bodies. Since the conformational properties of proteins in inclusion bodies exhibit many of the characteristics typical of amyloid fibrils. Based on these findings, we hypothesize that the rate at which proteins form amyloid fibrils may be predicted from their propensity to form inclusion b

CONCLUSIONS: The blood group antigen Vel has been one of immunohematology's greatest enigmas: the variation in antigen strength from one individual to another, the property of anti-Vel to readily hemolyze Vel+ red blood cells (RBCs), and the difficulty to screen for sufficient numbers of Vel- blood donors had made Vel a tough nut to crack. In 2013, a small, previously unknown protein called small

This chapter discusses the history of paleopathology in Sweden. Paleopathology of skeletal remains in Sweden is considered a subfield of historical osteology, a discipline that combines the study of human and animal bones from archaeological sites, with roots in the works of Nils-Gustaf Gejvall (1911–1991). The chapter describes the development of the field from its beginnings in paleopathological

The aim of the present article is to put culture on the agenda when discussing and working with IC reporting and IC management. Differences between Spain and Sweden in the Meritum work are discussed in relation to the interest and experience of IC among firms; and the way the firms develop IC management and IC reporting. We propose that culture might affect the assumptions of knowledge as well as

Globalization might affect the mix of jobs available in an economy and the rate at which workers gain skills. We develop a model in which firms differ in terms of productivity and skills and use the model to examine how globalization affects the wage distribution and the career path of workers as they move up the jobs ladder. There are two types of skills that determine a worker’s productivity in

The scope of the compendium covers many parts of theemerging circular economy. We choose to place considerablefocus on some of the substances that we extract from theground – in particular raw materials and critical materials.We focus on circularity in these areas, because presentlywe use too much, too fast, and we are not re-using nearlyenough. In turn, this approach demands that we look atthe te

Reproductive parasites such as Wolbachia can spread through uninfected host populations by increasing the relative fitness of the infected maternal lineage. However, empirical estimates of how fast this process occurs are limited. Here we use nucleotide sequences of male‐killing Wolbachia bacteria and co‐inherited mitochondria to address this issue in the island butterfly Hypolimnas bolina. We sho
