The circular economy is becoming a globalised phenomenon, but the regional emergence of circular business models differs significantly. By adopting a circular business institutionalisation perspective which bridges theory on institutional work and “ecologies of business models” we study the emergence of circular business models in Japan, a region with recent circular policy and business commitment

During the Middle Ages the concepts of `them and us' became concrete in the shape of fiercely defended frontiers, some of which were physical, geographic and political, while others were more ideological. This volume, the proceedings of an international symposium held at Lund University in 2000, presents twenty-four papers which examine the archaeological evidence for frontiers across Europe. Divi

Soils play a critical role in the carbon (C) cycle by regulating the atmospheric carbon dioxide (CO2) levels, and correspondingly the Earth’s climate. However, there are still countless questions of how biological and geochemical soil processes affect the C cycle. To be able to predict future implications on the Earth’s climate, we need to understand these processes. Globally, soils store more C tIron oxide nanoparticles are involved in several important biogeochemical processes. The interfaces between aqueous solutions and iron oxide nanoparticle surfaces are found everywhere in nature, and the chemical and microbial processes occurring at these complex interfaces control e.g. nutrient and contaminant availability and transport. Recently, it has been shown that certain ectomycorrhizal (EC

A dry release method for fabrication of suspended nanostructures is presented. The technique has been combined with an anti-stiction treatment for fabrication of nanocantilever based nanoelectromechanical systems (NEMS). The process combines a dry release method, using a supporting layer of photoresist which is removed using oxygen ashing in a reactive ion etcher (RIE), with CHF3 plasma induced de

Streptococcus pyogenes (group A streptococcus) causes a variety of diseases, including acute pharyngitis, impetigo, rheumatic fever and the streptococcal toxic shock syndrome. Moreover, S. pyogenes was responsible for the classical example of a nosocomial infection, the epidemics of puerperal fever (childbed fever) that caused the death of numerous women in earlier centuries. The most extensively

The nervous system is constantly infiltrated by blood-derived sentinels known as perivascular macrophages. Their immediate precursors have not yet been identified in situ and the mechanism that governs their recruitment is mostly unknown. Here, we provide evidence that CD68 (+)GR(-) monocytes can give rise to perivascular macrophages in mice suffering from endotoxemia. After adhesion to the endoth

Disturbed haemostasis is a central finding in severe Streptococcus pyogenes infection. In particular, microthrombi are found both at the local site of infection and at distant sites. Platelets are responsible for maintaining vascular function and haemostasis. We report here that M1 protein of S. pyogenes triggers immune-mediated platelet activation and thrombus formation. M1 protein is released fr

This study demonstrates that a cytotoxic serum reactivity not requiring the presence of complement appears in the sera of patients with acute myelogenous leukemia. The reaction is detected upon short‐term incubation of sera in vitro with autochthonous mononuclear white blood cells from peripheral venous blood of patients at the acute stage of the disease. This reactivity was demonstrated in 18/18

Despite the recent clinical success of T cell checkpoint inhibition targeting the CTLA-4 and PD-1 pathways, many patients either fail to achieve objective responses or they develop resistance to therapy. In some cases, poor responses to checkpoint blockade have been linked to suboptimal CD28 costimulation and the inability to generate and maintain a productive adaptive anti-tumor immune response.

Recently, to reach zero emission levels, some new energy systems based on fuel cells have been developed. This paper presents a review of investigations of these systems by thermodynamics performance, mainly, energy and exergy analysis. With energy analysis, the performance of an energy conversion system cannot be effectively and accurately evaluated. But exergy analysis complements and reinforces

Background: A unique feature of alveolar mast cells is their low high-affinity IgE receptor (FcεRI) expression. Recent discoveries in uncontrolled asthma suggest that the appearance of FcεRI-expressing alveolar mast cells may be a novel disease-specific feature of allergic asthma. This study investigates whether increased FcεRI-expressing alveolar mast cells are present in patients with mild aller

Corruption is indisputably an immense obstacle for many developing countries in their endeavor to prosper economically. Zambia, a peaceful, politically stable democracy is still facing many of the problems connected with corruption. Corruption has so far mostly been measured on a state-level, but in our thesis we narrow the field of investigation down to the ministry-level. We use questionnaires t

This review compares the methodology of published clinical studies investigating the extended-half-life (EHL) factor VIII (FVIII) products, rFVIIIFc (efmoroctocog alfa, Elocta®/Eloctate®), BAY 94-9027 (damoctocog alfa pegol, Jivi®), BAX 855 (rurioctocog alfa pegol, Adynovate®) and N8-GP (turoctocog alfa pegol, Esperoct®) including the phase 2/3 studies, A-LONG (NCT01181128), PROTECT VIII (NCT01580

The gene for an IgA-binding protein from a group A streptococcal strain was cloned and expressed in Escherichia coli. The IgA-binding protein, called protein Arp, was purified on IgA-Sepharose, allowing complete purification in a single step. Analysis of protein Arp by Western immunoblotting demonstrated a major IgA-binding band, with an apparent molecular weight of 42 kD. The purified protein was
