Fast-neutron/gamma-ray pulse-shape discrimination has been performed for the organic liquid scintillators NE 213A and EJ 305 using a time-of-flight based neutron-tagging technique and waveform digitization on an event-by-event basis. Gamma-ray sources and a Geant4-based simulation were used to calibrate the scintillation-light yield. The difference in pulse shape for the neutron and gamma-ray even
Let P be a set of n points in the Euclidean plane and let O be the origin point in the plane. In the k-tour cover problem (called frequently the capacitated vehicle routing problem), the goal is to minimize the total length of tours that cover all points in P, such that each tour starts and ends in O and covers at most k points from P. The k-tour cover problem is known to be NP-hard. It is also kn
Models for Non-Modelers focuses not on how to design models but on how to understand and critically appraise them. Data and statistical models are widely used in disciplines such as epidemiology, climate science and systems design, but it can be difficult for those without the necessary training to understand and implement them. This book is for non-modelers, especially social scientists. Through
Approaches integrating interdisciplinary perspectives are necessary to address current and future health and environmental challenges. Many policy initiatives have embraced more holistic approaches to tackle these challenges, e.g., the One Health concept, the Farm to Fork (F2F), Biodiversity and Chemical strategies within the European Green Deal and the global Sustainable Development Goals (SDGs).
Mali and Somalia have both suffered determined Islamist-inspired insurgencies, and in both African Union-led peace operations have been a central pillar in political and security stabilization efforts. Despite challenges in transferring lessons between unique situations, the AMISOM experience can offer some useful lessons for Mali. We have identified several themes that helped to drive success for
A large number of rachopharmaceuticals labelled with C-11 (half-time 0.340 h) are being developed for positron emission tomographic studies of different types of receptor in the human brain. For most of these agents, the available biokinetic data are insufficient to construct realistic compound-specific biokinetic models for calculating the internal radiation dose delivered to persons undergoing i
The output factor for a therapy photon beam is defined as the dose per monitor unit relative to the dose per monitor unit in a reference field. Convolution models for photon dose calculations yield the dose in units normalized to the incident energy fluence with phantom scatter intrinsically modeled. Output factors calculated with the convolution method as the dose per unit energy fluence relative
The aims of this study were to determine whether a registered nurse can collect information and plan a holistic and individual strategy for the treatment of patients with irritable bowel syndrome (IBS) and whether this approach can reduce these patients' health aspects. The referrals of 50 Swedish-speaking female patients aged between 18 and 65 years with the preliminary diagnosis of IBS were coll
History shows that companies that survive in a severe competitive climate are those that are highly adaptable to market and technological changes. Product development is one of the key activities that assure company survival by renewal of its offer to its customers. A scientific formalism has to be created to fulfill two purposes: 1) to ensure that the design and development of a product is succes

Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. Samtidigt möjliggör ökad beräkningskraft i moderna datorkluster att detaljerade simuleringar kan utföras för att stuClimate change is affecting our world and a more sustainable society is needed. The aviation industry is in need of change but aero-engines are very complex and take time to develop. Thermoacoustic instabilities have the power to destroy an engine, but also to reduce the environmental impact. At the same time, increasing computational power allows detailed simulations to be executed in order to st
This thesis examines communal living as a vision for future living. It covers historical communal living and its translation into modern-day practices. It explores our needs within communal living spaces along with the challenges they bring and investigates how design can balance private and communal spaces to support our evolving needs. The project outcome is a privacy sofa designed to support f
A Circular Economy (CE) calls for the value of materials and products to be maintained and recovered through narrowing, closing, and slowing loops. However, there remain challenges in moving up the waste hierarchy and not only recycling materials from products, but also capturing value through reuse of components in refurbished and repaired products. In this paper, we examine the practice of “harv
