Public policy has a critical role to play in supporting business actors towards their transition to more sustainable and less resource‐intensive practices within the context of a Circular Economy (CE). The European Union (EU) CE Action Plan sets a special focus on the role of business in adopting and promoting circular economic principles in their operations, and thus leading the transition toward

In this paper we study the application of boundary integral equation methods to the solution of the Helmholtz equation in a locally perturbed half-plane with Robin or impedance boundary conditions. This problem models outdoor noise propagation from a cutting onto a surrounding flat plane, and also the harbour resonance problem in coastal engineering. We employ Green's theorem to derive a system of

This article publishes results from a study on how formal equality is “done” in 48 individual action plans for handling social assistance. We use a street-level perspective to understand how policy is ‘done’ to enhance equality for applicants of social assistance. The analysis is based on theory on street-level bureaucracy as well as concept of equality. Applicants‘ difficulties with an uncompreh

Research on sustainability transitions has expanded rapidly in the last ten years, diversified in terms of topics and geographical applications, and deepened with respect to theories and methods. This article provides an extensive review and an updated research agenda for the field, classified into nine main themes: understanding transitions; power, agency and politics; governing transitions; civi

Introduction: Several blood-based biomarkers are associated with neuronal injury, but their utility in interventional clinical trials is unclear. This study retrospectively evaluated the utility of plasma neurofilament light (NfL) and total tau (t-tau) in an 18-month trial in mild Alzheimer's disease (AD). Methods: Correlation and conditional independence analyses and Gaussian graphical models wer

Demarketing is generally recognized as that aspect of marketing that aims at discouraging customers in general or a certain class of customers in particular on either a temporary or permanent basis and has been increasingly posited as a potential tool to degrow tourism and improve its overall sustainability, particularly as a result of so-called overtourism. The paper provides an overview of the v

Developing organisms typically mature earlier and at larger sizes in favorable growth conditions, while in rarer cases, maturity is delayed. The rarer reaction norm is easily accommodated by general life history models, whereas the common pattern is not. Theory suggests that a solution to this paradox lies in the existence of critical size thresholds at which maturation or metamorphosis can commen

Physical layer security has recently attracted considerable attention in the context of information-theoretic point of view. In this paper, we investigate relay selection schemes for security-constrained half-duplex cooperative wireless networks with multiple eavesdroppers, which have the ability to cooperate to overhear the source transmission. The proposed techniques select a trusted decode-and-

This paper presents a fully integrated 60 GHz frontend for phased array receivers. For the first time in the literature a phase controlled phased locked loop (PC-PLL) is used for beamforming at 60 GHz. The front-end performs a two stage frequency down-conversion, first from 60 GHz to 20 GHz, then from 20 GHz to quadrature baseband. Both the local oscillator signals at 20 GHz and 40 GHz are generat

Mechano-regulation during tendon healing, i.e. the relationship between mechanical stimuli and cellular response, has received more attention recently. However, the basic mechanobiological mechanisms governing tendon healing after a rupture are still not well-understood. Literature has reported spatial and temporal variations in the healing of ruptured tendon tissue. In this study, we explored a c

We present a case of a patient in a severe pulmonary mucormycosis during the neutropenic phase of treatment for acute myeloblastic leukaemia (AML), type M2. He had two major risk factors for setting infection; leukaemia and diabetes mellitus. Although he received antimicrobial and antifungal therapy with Amphotericin B in time, it was unable to eradicate infection. We performed a pneumectomy, whic

A program to simulate the production of heavy quarks through the boson-gluon fusion process in e±p collisions is presented. The full electroweak structure of the electron-gluon interaction is taken into account as well as the masses of the produced heavy quarks. Higher order QCD radiation is treated using initial and final state parton showers, and hadronization is performed using the Lund string

The Monte Carlo generator MAJOR 1.5 simulates the production and decay of heavy Majorana neutrinos via lepton mixing or exchange of 'light' right-handed W-bosons in deep inelastic scattering, i.e. e±p → NX → e±W∓X or veZX. Physics and programming aspects are described in this manual.

Spiral wound modules are the most common modules in the industry due to their low investment and replacement costs plus high packing density. The use of spiral wound modules is often restricted to feed streams with a low temperature (< 75°C) and a low viscosity. The focus of this paper is on a new generation of spiral wound modules, which has been introduced by Alfa Laval Membrane Technology for

Membrane fouling is a constant challenge of membrane processes in separation and purification of organic, biomass originated compounds in food, biorefining and biotechnology industries. It persists due to the complexity and high fouling tendency of the bio-based streams and may result in a decrease of filtration capacity, rejection alteration, reduction of membrane lifetime and increase of operati

A method for the fractionation of aerosol particles with respect to size and ability to grow with an increased relative humidity has been developed. The system consists of cascade impactors, diffusion driers, a humidifier and a temperature stabiliser. Diffusion driers were designed and the vapour penetration was modelled below 20%. A humidifier which can be operated with an output relative humidit

This paper is the first part of a program to deal with the relative importance of the different effects in a colour dipole field when the field energy is transformed into hadrons according to a statistical scheme with the sole constraints coming from energy and momentum conservation and the requirements of scaling. In this paper we treat the meson distributions from quark fragmentation with partic
