Ammonia (NH3) is currently in the spotlight because of its potential in serving as an energy resource devoid of carbon. Combustion of NH3, however, presents several drawbacks, such as high ignition temperature, low flame speed, and high NOx emissions. Furthermore, although dual-fuel approaches may provide a solution for some of these problems, scarcity of information on the resulting emissions inh

The term “history of knowledge” has gained traction in recent years. This forum section seeks to explore a prominent concept in this new field—circulation—as well as to demonstrate the value of studying knowledge circulation for the history of humanities. While the study of the transmission of knowledge has been pursued in adjacent fields, such as the history of science or media studies, it is arg

The purpose of this essay is to demonstrate how a new history of the postwar humanities could be written. Drawing on approaches from the history of knowledge and other adjacent fields, it outlines a study of the conditions of the circulation of knowledge in the public sphere during the 1960s and 1970s. By introducing “arena of knowledge” as an analytical concept, the essay highlights certain media

Management of the constructed facility has often been an afterthought among the professions and disciplines in the real estate and construction industries. Consequently, too many facilities fail to meet their operational requirements to the full. Briefing has been defined as the process of identifying and analysing the needs, aims and constraints (i.e. the resources and the context) of the client

Introduction: A new grading of exercise capacity during bicycle stress testing has been proposed in Sweden based on the new reference material (‘the Kalmar material’), which has not been validated. We aimed to examine the prognostic information of the new grading of exercise capacity during exercise stress testing. Methods: Data on all bicycle exercise tests performed at the Department of Clinical

This thesis is built around an observational study of a class at an elite school. The study follows the class through their upper secondary school education (ages 16-19), focusing on social science lessons. I have used ethnographic methodology to describe and problematize how social science and value-based ambitions of equality conflict with the student role of superiority cultivated at this schoo

This cross-sectional study investigated performed activities and the level of satisfaction with everyday occupations among people (n = 67) with advanced Parkinson’s disease (PD), and how these factors and experiences of social relationships were related to mental well-being. Managing one’s hygiene and physical exercises were activities that the majority still performed, whereas few were engaged in

Emerging theoretical concepts for quantum technologies have driven a continuous search for structures where a quantum state, such as spin, can be manipulated efficiently. Central to many concepts is the ability to control a system by electric and magnetic fields, relying on strong spin-orbit interaction and a large g-factor. Here, we present a mechanism for spin and orbital manipulation using smal

The procedure of aligning a positron emission tomography (PET) image with a common coordinate system, spatial normalization, typically demands a corresponding structural magnetic resonance (MR) image. However, MR imaging is not always available or feasible for the subject, which calls for enabling spatial normalization without MR, MR-less spatial normalization. In this work, we propose a template-

Isosorbide-5-methacrylate was obtained by enzymatic catalysis with Lipozyme RM IM in a highly regioselective manner in up to 87% yield. The process uses readily available acyl donors (methacrylic anydride or vinyl methacrylate), is easily scalable and chromatography free. Simple extractive workup followed by decoloration and filtration affords the monomer with up to > 99% purity. In addition, the

BACKGROUND: Mental health problems are the main cause of sick leave in today's working age population. Employers are responsible for their employees' work environment and preventing work-related illnesses, but their knowledge regarding mental health problems is lacking. Employer beliefs and support strategies need further exploration. OBJECTIVE: To explore employers' beliefs, knowledge and strateg

In recent years, Sweden has tightened its legislation in a number of areas which provides the society good opportunities for combating street violence, writes Criminologist Ardavan Khoshnood.

This chapter analyses the European Union’s efforts to counteract the erosion of member states’ corporate tax bases. The author first describes how multinational enterprises, like Apple, have been able to exploit differences between the tax systems in order to pay less taxes. The author then presents the hypothesis that EU member states have managed to defend their interests in protecting their own

The Shortest Vector Problem (SVP) is one of the mathematical foundations of lattice based cryptography. Lattice sieve algorithms are amongst the foremost methods of solving SVP. The asymptotically fastest known classical and quantum sieves solve SVP in a $d$-dimensional lattice in $2^{\const d + \smallo(d)}$ time steps with $2^{\const' d + \smallo(d)}$ memory for constants $c, c'$. In this work, w

In this article, we aim to contribute to the literature on social identification among migrants and minorities by offering a theoretical framework that accounts for the interplay of socio-psychological factors, local and transnational group dynamics, and the socio-political environment in which migrants live. This approach enables us to analyse not only the political significance of identity, but
