Artikel om synen på och debatter om monument och statyer med koppling till amerikanska inbördeskriget, framför allt i sydstaterna.

Executive functions (EF) denote the host of top-down mental processes that mediate self-regulation to achieve a goal. Among other things, EF support cognitive flexibility by allowing inhibition of automatic responses in favour of obtaining future goals. Corvids, the bird group that is comprised of ravens, crows and jays, are distinguished by their cognitive flexibility. This thesis investigates tw

This thesis collects contributions to wireline and wireless communication systems with an emphasis on multiuser and multicarrier physical layer technology. To deliver increased capacity, modern wireline access systems such as G.fast extend the signal bandwidth up from tens to hundreds of MHz. This ambitious development revealed a number of unforeseen hurdles such as the impact of impedance changes

This paper presents achievable uplink (UL) sum-rate predictions for a measured line-of-sight (LOS) massive multiple-input, multiple-output (MIMO) (MMIMO) scenario and illustrates the trade-off between spatial multiplexing performance and channel de-coherence rate for an increasing number of base station (BS) antennas. In addition, an orthogonal frequency division multiplexing (OFDM) case study is

Governance of common resources such as water calls for rethinking structure, legal frameworks and property rights. In order to promote the decentralization of water governance, Water User Associations (WUAs) were created in many countries, such as India and Turkey, to operate and maintain irrigation systems as well as take over the responsibility of water distribution among water users. Despite pr

CA125 is the best ovarian cancer early detection marker to date; however, sensitivity is limited and complementary markers are required to improve discrimination between ovarian cancer cases and non-cases. Anti-CA125 autoantibodies are observed in circulation. Our objective was to evaluate whether these antibodies (1) can serve as early detection markers, providing evidence of an immune response t

En del av ett konstprojekt som handlar om kommunismens historia i Rumänien och intervjuer med politiska fångar.

Animal diversification on Earth has long been presumed to be associated with the increasing extent of oxic niches. Here, we challenge that view. We start with the fact that hypoxia (

A novel pH and temperature dual-responsive bioconjugate is prepared by grafting thermoresponsive polymer chains from a pH-responsive protein amelogenin via atom transfer radical polymerization. To the best of our knowledge, this is the first time that amelogenin is exploited to prepare a hybrid biomaterial with new stimuli-responsive property. In both basic and acidic solutions the protein-polymer

Nanoparticles affect the immune system as they may interact directly with immune cells and activate them. However, it is possible that nanoparticles also interact with released cytokines and immunologically active enzymes. To test this hypothesis, the activity of myeloperoxidase released from activated neutrophils was measured in the presence of nanoparticles with different chemistry and size. In

Objectives: Aerococcus urinae and Aerococcus sanguinicola cause urinary tract infections (UTIs) and antibiotic treatment recommendations are solely based on in vitro findings and limited clinical experience. Our objective was to investigate the effectiveness of different treatment strategies in aerococcal UTI through a prospective observational study. Methods: Urine samples with aerococci were ide

Den här avhandlingen handlar om luftburna designade nanopartiklar och hur mantar reda på vilka egenskaper de har. Luftburna partiklar eller aerosoler är något sommänniskan alltid har haft omkring sig. Oavsett om det varit i form av pollen, rök fråneldstaden, eller från astmainhalatorn så har de alltid varit där och påverkat oss. I varjeandetag drar vi in flera tusen partiklar, men vilken typ de ärThis thesis will explore parts of the life of engineered nanoparticles, from generation in research environments andprocess monitoring, to emissions in an industrial setting. The aim is to give insights into how the particles can becharacterized in different settings and how different characterization methods can be applied depending on need ordemand.Airborne nanoparticles have been around forever
