Current trends in diffusion NMR and MRI methods development are reviewed. While great efforts are still directed towards further improving the spectral, spatial, and relaxation rate resolution of basic diffusion measurements, recent improvements in magnetic field gradient technology on whole-body scanners have enabled an exciting line of research involving MRI implementations of advanced diffusion
Purpose: The purpose of this paper is to enhance the heat transfer and thermal performance in the trailing edge region of the vane with vortex generators (VGs). Design/methodology/approach: This numerical study presents the enhancement of thermal performance in the trailing part of a gas turbine blade. In the trailing part, generally, pin fins are used either in staggered or in-line arrangements t
Aseptic loosening of implants is the major cause for revision surgery. By modulating the bone-implant interface, early bone-implant anchorage could be improved. Implant surface manipulation by the addition of osteopromotive molecules locally and systemically to promote implant integration has been described with limited success. This study describes a novel approach by making the implant capable o
Ultrafast dynamics of photoinduced charge transfer processes in light-harvesting systems based on Earth-abundant transition metal complexes are of current interest for the development of molecular devices for solar energy conversion applications. A combination of ultrafast spectroscopy and first principles quantum chemical calculations of a recently synthesized iron carbene complex is used to eluc
Background: How we identify ourselves is strongly related to employment. Young adults are a vulnerable group with regard to entering the Labor market. If they also have mental health problems, entering becomes more difficult and increases risk of early marginalization. Nevertheless, working can be essential for personal recovery process. Aims: To explore experiences of young adults with mental hea
Using a sample of large US firms, this study shows that blockholders in combination with liquidity can contribute positively to innovation (R&D investments). We contribute to the literature on managerial myopia that has focused mainly on large owners and their type (short-term/long-term). Our results are in line with recent theoretical studies arguing that blockholders in combination with mark
How do crisis perceptions interrelate with the emergence and re-constitution of policy problems? By using a novel combination of interviews with a content and network analysis of hand-coded parliamentary questions, this article maps the emergence of brain drain as a policy problem at the level of the European Union and follows the evolution of the issue over the last four parliamentary periods (fr
In the age of globalization, local memories of past violence are often dislocated from their material places as remembrance is transpiring in transnational memory spaces. Historical events and commemorative memory practices increasingly transcend national boundaries and change the way memories of historical violence, atrocity, and genocide are represented in the transnational memoryscape. This art
This article explores the evolution and determinants of public support for the euro since its creation in 1999 until the end of 2017, thereby covering the pre-crisis experience of the euro, the crisis years and the recent recovery. Using uniquely large macro and micro databases and applying up-to-date econometric techniques, the authors revisit the growing literature on public support for the euro
Microorganisms in wastewater treatment plants (WWTPs) are essential for water purification to protect public and environmental health. However, the diversity of microorganisms and the factors that control it are poorly understood. Using a systematic global-sampling effort, we analysed the 16S ribosomal RNA gene sequences from ~1,200 activated sludge samples taken from 269 WWTPs in 23 countries on
Numerous species adopt inducible defence strategies; that is, they have phenotypically plastic traits that decrease the risk of capture and consumption by potential predators. The benefits of expressing alternative phenotypes in high- vs. low-risk environments are well documented. However, inducible anti-predator traits are also expected to incur costs, as they are not expressed when predators are
X-ray free-electron lasers (FELs), which amplify light emitted by a relativistic electron beam, are extending nonlinear optical techniques to shorter wavelengths, adding element specificity by exciting and probing electronic transitions from core levels. These techniques would benefit tremendously from having a stable FEL source, generating spectrally pure and wavelength-tunable pulses. We show th
Occupational safety and health (OSH) is a vital part of the right to health. While the International Labor Organization (ILO) historically treated OSH as an entirely technical matter, it has increasingly been influenced by a human rights agenda. The ILO has responded by adopting and promoting a large number of international standards-in the form of conventions, recommendations, and codes of practi
A recent approach for measurement program planning, GQM+Strategies, provides an important extension to existing approaches linking measurements and improvement activities to strategic goals and ways to achieve these goals. There is a need for instruments aiding in eliciting information from stakeholders to use GQM+Strategies. The success of GQM+Strategies highly depends on accurately identifying g
Context: The global software industry and the software engineering (SE) academia are two large communities. However, unfortunately, the level of joint industry-academia collaborations in SE is still relatively very low, compared to the amount of activity in each of the two communities. It seems that the two ’camps’ show only limited interest/motivation to collaborate with one other. Many researche

During exploratory testing sessions the tester simultaneously learns, designs and executes tests. The activity is iterative and utilizes the skills of the tester and provides flexibility and creativity. Test charters are used as a vehicle to support the testers during the testing. The aim of this study is to support practitioners in the design of test charters through checklists. We aimed to ident
