Ramjet propulsion is commonly preferred to power supersonic and hypersonic vehicles for cruising faster than Mach 3. This is an elegant solution owing to the lean architecture which does not embody any rotating parts. Although the geometry of the engine is simple as compared to turbine based configurations, the flow physics through the engine duct is quite complex and the flow speeds modulate betw

Background: Population-based register data could be used to improve our knowledge of patients surgically treated for foot and ankle disorders. The quality register Swefoot was recently created to collect surgical and patient-reported data of foot and ankle surgery. This manuscript aims to describe the development and current use of the register. Methods: The development of Swefoot started in 2014

In this article, we investigate public support for eco-social policies combining goals of social justice and ecological sustainability. Eco-social policies contribute both to providing a social floor or redistributing resources to where they are needed and to respecting an ecological ceiling by keeping human activities within ecological limits. We discuss five such policies and highlight arguments

Blood-based markers (BBMs) have recently shown promise to revolutionize the diagnostic and prognostic work-up of Alzheimer's disease (AD), as well as to improve the design of interventional trials. Here we discuss in detail further research needed to be performed before widespread use of BBMs. We already now recommend use of BBMs as (pre-)screeners to identify individuals likely to have AD patholo

Contemporary research and teaching on global environmental politics (GEP) draw upon many approaches to understanding the ways in which states and societies respond to transboundary environmental problems (see Chapter 2). Approaches that emphasize the state (see Chapter 7) and international organizations (see Chapter 8) derive in a straightforward way from scholarly work in international relations

This paper studies how degraded material properties in near proximity to the cut edge influence the torque performance of an axial-flux induction machine. The magnetically degraded areas are characterized using a layering approach, where the magnetic hysteresis curve describing the material is remodeled so that the field strength required to reach a specific value of magnetic flux density is incre

Nondestructive testing of composite materials is important in aerospace applications, and mm-wave imaging has been increasingly used for this purpose. Imaging is traditionally performed using Fourier methods, with inverse methods being an alternative. This communication presents a mm-wave imaging method with an inverse approach intended for nondestructive testing of singly curved composite panels

The construction industry is often described as mature, conservative and resistant to change in research studies, governmental reports as well as in media. Both scholars and policy makers thereby find it critical to encourage innovation, development, and change within the construction industry. This study takes on a different perspective by investigating changes that have actually taken place. The

Effective domestic revenue mobilization has gained renewed urgency, especially in the light of the need to recover from the COVID-19 pandemic. In taxation debates, the ‘informal sectors’ have hitherto been assumed to be a part of the problem and implicitly mistaken for lucrative tax bases. First, I critically interrogate current conceptualizations of informality to highlight how the informality

Detta kapitel handlar om samverkan mellan sektorer och organisationer som en metod för social förändring. Vi vill med detta kapitel både beskriva en särskild metod för samverkan och reflektera över dess möjligheter och utmaningar. Metoden har utvecklats av Sensus studieförbund (Region Skåne-Blekinge) som är en av de stora organisationer som driver folkbildning i Sverige idag. Utgångspunkten för me

Chemicals is the industrial sector with the highest energy demand, using a substantial share of global fossil energy and emitting increasing amounts of greenhouse gasses following rapid growth over the past 25 years. Emissions associated with energy use have increased with growth in coal-dependent regions but are also commonly underestimated in regions with higher shares of renewable energy. Renew

BACKGROUND AND PURPOSE: Myeloablative Total Body Irradiation (TBI) is an important modality in conditioning for allogeneic hematopoietic stem cell transplantation (HSCT), especially in children with high-risk acute lymphoblastic leukemia (ALL). TBI practices are heterogeneous and institution-specific. Since TBI is associated with multiple late adverse effects, recommendations may help to standardi
