Internal dose assessment of 148Gd using isotope ratios of gamma-emitting 146Gd or 153Gd in accidently released spallation target particles

The pure alpha emitter 148Gd may have a significant radiological impact in terms of internal dose to exposed humans in case of accidental releases from a spallation source using a tungsten target, such as the one to be used in the European Spallation Source (ESS). In this work we aim to present an approach to indirectly estimate the whole-body burden of 148Gd and the associated committed effective

Ambipolar Behavior of Ge-Intercalated Graphene : Interfacial Dynamics and Possible Applications

For the realization of graphene-based electronic and optic devices, the functionalization of this material becomes essential. Graphene doping through intercalation and tuning the chemical potential is one among other promising concepts. Intercalation of germanium is particularly interesting in view of its ambipolar doping behavior. Both p- and n-type doped graphene and their doping levels were ide

Third time recurrent Boerhaave’s syndrome : a case report

Background: Effort rupture of the esophagus or Boerhaave’s syndrome is a rare entity, and prognosis is largely dependent on early diagnosis and treatment. Recurrent effort ruptures are very rare, only reported in a few case reports in English literature. We present a case with a third time effort rupture, and to the best of our knowledge there are no such previous publications. Furthermore, the pr

The augmentation of internal tip heat transfer in gas turbine blades using a pair of delta-winglet vortex generators

A novel method to enhance the heat transfer on the internal tip surface of gas turbine blades was developed. Effects of delta-winglet vortex generators (DWVG) and their angle of attack on the vortical structures and mechanism of enhanced heat transfer were investigated. Seven different angles of attack were considered: 0°, 15°, 30°, 45°, 60°, 75°, and 90°. The Reynolds number varies from 10,000 to

Poverty in contemporary economic thought

Poverty in Contemporary Economic Thought aims to describe and critically examine how economic thought deals with poverty, including its causes, consequences, reduction and abolition. This edited volume traces the ideas of key writers and schools of modern economic thought across a significant period, ranging from Friedrich Hayek and Keynes to latter-day economists like Amartya Sen and Angus Deaton

Introduction : Poverty in contemporary economic thought

This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides presentation of the work of the economists who received the 2019 Prize in Economic Sciences in Memory of Alfred Nobel. It deals almost exclusively with poverty within a nation, with the situation of individuals in society. The book explores the perspective to a comparison

Economical effect on doubling of COVID-19 cases : Examples of rich versus poor countries

PurposeThe paper aims to examine some economical, political and health system indicators on the transmission of the COVID-19 transmission within the national system. The main objective is to investigate what are the most effective indicators which have led to the declared numbers by countries.Design/methodology/approachThis study combined multiple sets of data to describe best the economical statu

Improving together : Better science writing through peer learning

Science, in our case the climate and geosciences, is increasingly interdisciplinary. Scientists must therefore communicate across disciplinary boundaries. For this communication to be successful, scientists must write clearly and concisely, yet the historically poor standard of scientific writing does not seem to be improving. Scientific writing must improve, and the key to long-term improvement l

Placement Optimization in Refugee Resettlement

Every year, tens of thousands of refugees are resettled to dozens of host countries. Although there is growing evidence that the initial placement of refugee families profoundly affects their lifetime outcomes, there have been few attempts to optimize resettlement decisions. We integrate machine learning and integer optimization into an innovative software tool, Annie™ Matching and Outcome Optimiz

Data and Optimization Requirements for Kidney Exchange Programs

Kidney Exchange Programs (KEP) are valuable tools to increase the options of living donor kidney transplantation for patients with end-stage kidney disease with an immunologically incompatible live donor. Maximising the benefits of a KEP requires an information system to manage data and to optimise transplants. The data input specifications of the systems that relate to key information on blood gr

Outdoor Office Work – An Interactive Research Project Showing the Way Out

The physical boundaries of office work have become increasingly flexible. Work is conducted at multiple locations outside the office, such as at clients’ premises, at home, in cafés, or when traveling. However, the boundary between indoor and outdoor environment seems to be strong and normative regarding how office work is performed. The aim of this study was to explore how office work may be cond

Evaluating competition for forage plants between honey bees and wild bees in Denmark

A recurrent concern in nature conservation is the potential competition for forage plants between wild bees and managed honey bees. Specifically, that the highly sophisticated system of recruitment and large perennial colonies of honey bees quickly exhaust forage resources leading to the local extirpation of wild bees. However, different species of bees show different preferences for forage plants

Coupling Microplate-Based Antibacterial Assay with Liquid Chromatography for High-Resolution Growth Inhibition Profiling of Crude Extracts : Validation and Proof-of-Concept Study with Staphylococcus aureus

With the identification of novel antibiotics from nature being pivotal in the fight against human pathogenic bacteria, there is an urgent need for effective methodologies for expedited screening of crude extracts. Here we report the development and validation of a simple and dye-free antimicrobial assay in 96-well microplate format, for both determination of IC50 values and high-resolution inhibit

Dietary quercetin impacts the concentration of pesticides in honey bees

Honey bees are important pollinators and are subject to numerous stressors, such as changing floral resources, parasites, and agrochemical exposure. Pesticide exposure has been linked to the decline in the global honey bee population. We have limited knowledge of the metabolic pathways and synergistic effects of xenobiotics in bees. Quercetin is one of the most abundant phytochemicals in plants an

Iran Might Purge Its Intelligence and Counterintelligence Community

Mohsen Rezaee, a high-ranking official of the Islamic Republic in Iran, has admitted that top-secret Iranian nuclear documents were stolen in a raid of a Tehran warehouse by Israeli operatives in 2018—a raid the regime had denied ever occurred. Rezaee is calling for a purge of the Iranian intelligence and counterintelligence community, which could result in Iranian intelligence operatives fleeing

Poverty and new welfare economics

What is New Welfare Economics (NWE), how does it explain poverty, and what can we learn from this school of thought when it comes to poverty relief? Answering these questions is the aim in this chapter. The chapter opens with a description of the development of NWE and its central tools and concepts, providing a non-technical explanation of the differences between ʼnew’ and ‘old’ welfare economics.
