A new approach to semantic sustainability assessment: text mining via network analysis revealing transition patterns in German municipal climate action plans

Background Various monitoring approaches have shown that urban areas and their energy systems are major contributors to climate change. Corresponding observations have mostly been based on physical data. However, text data is an untapped source of information that can be analyzed by text mining methods. Taking the example of the German Energy Transition, an interpretation network ...

The influence of surface texture and wettability on initial bacterial adhesion on titanium and zirconium oxide dental implants

Background This study aims to investigate bacterial adhesion on different titanium and ceramic implant surfaces, to correlate these findings with surface roughness and surface hydrophobicity, and to define the predominant factor for bacterial adhesion for each material. Methods Zirconia and titanium specimens with different surface textures and wettability (5.0 mm in diameter, 1.0 ...

Same but different? Measurement invariance of the PIAAC motivation-to-learn scale across key socio-demographic groups

Background Data from the Programme for the International Assessment of Adult Competencies (PIAAC) revealed that countries systematically differ in their respondents’ literacy, numeracy, and problem solving in technology-rich environments skills; skill levels also vary by gender, age, level of education or migration background. Similarly, systematic differences have been documented ...

Assessment of performance and parameter sensitivity of multicomponent geothermometry applied to a medium enthalpy geothermal system

The determination of reservoir temperatures represents a major task when exploring geothermal systems. Since the uncertainties of classical solute geothermometry are still preventing reliable reservoir temperature estimations, we assess the performance of classical geothermometers and multicomponent geothermometry by applying them to fluids composed from long-term batch-type ...

Economic Growth in the USA and Germany 1960–2013: The Underestimated Role of Energy

Economic growth in Germany and the USA between the years 1960 and 2013 is analyzed, using two LinEx production functions \(Y_{L1}(K,L,E;t)\) and \(Y_{L11}(K,L,E;t)\), which depend linearly on energy and exponentially on quotients of the production factors capital K(t), labor L(t), and energy E(t). The two production functions result from output elasticities that are the simplest, ...

Decoupled signal detection for the uplink of massive MIMO in 5G heterogeneous networks

Massive multiple-input multiple-output (MIMO) systems are strong candidates for future fifth-generation (5G) heterogeneous cellular networks. For 5G, a network densification with a high number of different classes of users and data service requirements is expected. Such a large number of connected devices needs to be separated in order to allow the detection of the transmitted ...

Some general points on the \(I^2\) -measure of heterogeneity in meta-analysis

Meta-analysis has developed to be a most important tool in evaluation research. Heterogeneity is an issue that is present in almost any meta-analysis. However, the magnitude of heterogeneity differs across meta-analyses. In this respect, Higgins’ \(I^2\) has emerged to be one of the most used and, potentially, one of the most useful measures as it provides quantification of the ...

Tobacco dependence among people with mental illness: a facility-based cross sectional study from Southwest Ethiopia

Background Tobacco smoking is a health care issue in developed as well as in developing countries. Tobacco smoking among people with mental illness is significantly higher than in the general population. Tobacco smoking has negative effects on physical, mental and financial well-being of people with mental illness but little is known about tobacco dependence among mental health ...

Pharmacokinetics, microscale distribution, and dosimetry of alpha-emitter-labeled anti-PD-L1 antibodies in an immune competent transgenic breast cancer model

Background Studies combining immune checkpoint inhibitors with external beam radiation have shown a therapeutic advantage over each modality alone. The purpose of these works is to evaluate the potential of targeted delivery of high LET radiation to the tumor microenvironment via an immune checkpoint inhibitor. Methods The impact of protein concentration on the distribution of ...

Generic atorvastatin is as effective as the brand-name drug (LIPITOR®) in lowering cholesterol levels: a cross-sectional retrospective cohort study

Background In a world of ever increasing health care costs, generic drugs represent a major opportunity to ensure access to essential medicines for people who otherwise would be unable to afford them. However, some clinicians and patients are still questioning the safety and effectiveness of generic formulations compared to the proprietary drugs necessitating further systematic ...

Modelling and implementation of virtual radio resources management for 5G Cloud RAN

The virtualisation of Radio Access Networks (RANs) is one of the goals in designing 5G mobile networks. This paper aims at presenting a proof of concept for the virtualisation of radio resources using Open Air Interface (OAI), a software-based Long-Term Evolution (LTE) eNodeB physical emulator. OAI was extended to support multi-tenancy, representing diverse Virtual mobile Network ...

Comparison of the polyphenolic profile and antibacterial activity of the leaves, fruits and flowers of Rhododendron ambiguum and Rhododendron cinnabarinum

Background Rhododendron species have been traditionally used in countries like China, Nepal, Russia and North America for treating human diseases. These species are known to be a good source of polyphenolic plant secondary plant metabolites. They are known to have beneficial health properties for humans and have been used to treat diseases like asthma, skin diseases. In this ...

An approach to geometry-based dynamic location referencing

Introduction An important requirement for knowledge infrastructures in smart cities is the continuous updating of location-based information. Protocols for dynamic location referencing like e.g. OpenLR or AGORA-C tackle the problem of accurately matching locations between dissimilar digital maps. They are map-agnostic and aim at limiting the amount of descriptive data to reduce ...

Where are the SVHCs?

Background The European chemicals regulation REACH includes the legal duty for suppliers to inform consumers on request about the presence of substances of very high concern (SVHCs) in articles. Since this requirement has been in force now for 10 years, the intention of this study was to find out whether information on SVHCs is adequately communicated to the consumer today. Data on ...
