The standardized description of collections is an important means for prioritizing collection digitization on a supra-institutional level. Different organizational and systematic structures prevent easy comparison of collections sizes and foci, in order to make informed decisions on setting priorities and efficiently distributing tasks. In autumn 2018, the consortium of German Natural Sciences Collections (DCOLL), consisting of seven natural history collections holding institutions integrated as a National Research Infrastructure*1 performed a top-level description of the consortium's collections based on a subset of the criteria defined by the One World Collection Working Group (OWC). OWC is based on an initiative of the directors of the world's largest Natural Science Collections and aims at making collections and ressource allocations comparable. Categories relating to the staff structure of institutions were omitted, as those were considered sensitive and of little use for the purpose. The survey focused on collection size and geographical distribution only. Since some partners already had previously assembled the necessary data and since the OWC criteria are based on a reasonably high level, allowing the integration of heterogenous collections, the OWC dashboard presented an opportunity to achieve quick standardized results. However, as one purpose of the survey was to support decisions on the consortium's digitization strategy, arguably not the objective of OWC, a field to describe the digitization rate had to be added. Another shortcoming of the OWC dashboard for this purpose was the difficulty in subsuming some important sub-collections into the given criteria, namely digital collections (like animal sound archives) and non-biological or non-geological collections (e.g. historical objects and archives). On the positive side, the survey proved to be very helpful to indicate the consortium's collection focus in comparison with other institutions on an international level. This can provide valuable information for establishing an integrated collection development and digitization strategy on a supra-institutional level. It can be shown for example that 41% of the objects with origin from Europe in Natural Science Collections are held by DCOLL. While it may be possible to derive meaningful strategic goals from this information, it is a big challenge to implement practical objectives based on the same criteria. From a bottom-up perspective the OWC dashboard aggregates data, which were collected in a non-standardized form within institutions across organizational structures. Increasing the granularity from this level will result in an unreasonable effort. This presentation discusses the process of collecting information based on the OWC criteria and will present the collection structure of DCOLL.

Within the Netherlands, large scale digitization efforts of natural science collections have taken place in recent years. This has led to a wealth of digital information on natural science collections. Still, large quantities of collection data remain untapped and undigitized. The usage of all these digital collections data as driver for science and society remains underexplored. Especially important, is the opportunity for such data to be combined and/or enriched with other data types with the aim to empower different user groups. A consortium of Dutch partners has committed themselves in working together to make biological and geological collections into a joint research infrastructure, underpinning other research infrastructures and scientific uses also beyond the biodiversity research domain. This consortium combines the Dutch contribution to the Distributed Systems of Scientific Collections (DiSSCo), LifeWatch, the Catalogue of Life and the Global Biodiversity Information facility, under the coordination of the Netherlands Biodiversity Information Facility. As part of a preparatory project for DiSSCo, funded by the Dutch science council, we connected the different users groups of collection managers (data providers), scientists (end-users), IT-specialists and policymakers. With collection managers we explored how to move towards an overview of all natural science collections in the Netherlands. In addition, we studied to what extent collection holdings of different musea could be combined, managed, and shared into one research infrastructure. Using a research data management cycle perspective, we surveyed and interviewed the Dutch research community for the barriers and opportunities in using natural science collections and related data. The outcomes of the project should lead to the next steps in creating a more comprehensive and inclusive biodiversity research data infrastructure in the Netherlands that interacts seamlessly with existing international research infrastructures, including DiSSCo.

The purpose of this paper is to propose an effective strategy for the design of turbine blades with underplatform dampers (UPDs). The strategy involves damper “pre-optimization,” already proposed by the authors, to exclude, before the blades-coupled nonlinear calculation, all those damper configurations leading to low damping performance. This paper continues this effort by applying pre-optimization to determine a damper configuration which will not jam, roll, or detach under any in-plane platform kinematics (i.e., blade bending modes). Once the candidate damper configuration has been found, the damper equilibrium equations are solved by using both the multiharmonic balance method (MHBM) and the direct-time integration (DTI) for the purpose of finding the correct number of Fourier terms to represent displacements and contact forces. It is shown that contrarily to non-preoptimized dampers, which may display an erratic behavior, one harmonic term together with the static term ensures accurate results. These findings are confirmed by a state-of-the-art code for the calculation of the nonlinear forced response of a damper coupled to two blades. Experimental forced response functions (FRF) of the test case with a nominal damper are available for comparison. The comparison of different damper configurations offers a “high-level” validation of the pre-optimization procedure and highlights the strong influence of the blades mode of vibration on the damper effectiveness. It is shown that the pre-optimized damper is not only the most effective but also the one that leads to a faster and more flexible calculation.

An anaerobic inverse turbulent bed, in which the biogas only ensures fluidisation of floating carrier particles, was investigated for carbon removal kinetics and for biofilm growth and detachment. The range of operation of the reactor was kept within 5 and 30 kgCOD· m−3· d−1, with Hydraulic Retention Times between 0.28 and 1 day. The carbon removal efficiency remained between 70 and 85%. Biofilm size were rather low (between 5 and 30 μm) while biofilm density reached very high values (over 80 kgVS· m−3). The biofilm size and density varied with increasing carbon removal rates with opposite trends; as biofilm size increases, its density decreases. On the one hand, biomass activity within the reactor was kept at a high level, (between 0.23 and 0.75 kgTOC· kgVS· d−1, i.e. between 0.6 and 1.85 kgCOD·kgVS · d−1).This result indicates that high turbulence and shear may favour growth of thin, dense and active biofilms. It is thus an interesting tool for biomass control. On the other hand, volatile solid detachment increases quasi linearly with carbon removal rate and the total amount of solid in the reactor levels off at high OLR. This means that detachment could be a limit of the process at higher organic loading rates.

By applying the concept of natural science to the study of music, on the one hand, we can understand the structure of music macroscopically, on the other, we can reflect on the history of music to a certain extent. Throughout the history of western music, from the classical period to the 20th century, music seems to have gone from order to disorder, but it is still orderly if analyzed carefully. Using the concept of complex information systems can give a good answer in the essence.

Abstract Many years ago, Emmanuel Todd came up with a classification of family types and argued that the historically prevalent family types in a society have important consequences for its economic, political, and social development. Here, we evaluate Todd's most important predictions empirically. Relying on a parsimonious model with exogenous covariates, we find mixed results. On the one hand, authoritarian family types are, in stark contrast to Todd's predictions, associated with increased levels of the rule of law and innovation. On the other hand, and in line with Todd's expectations, communitarian family types are linked to racism, low levels of the rule of law, and late industrialization. Countries in which endogamy is frequently practiced also display an expectedly high level of state fragility and weak civil society organizations.

Covalent Interactions

The S66 benchmark for non-covalent interactions has been re-evaluated using explicitly correlated methods with basis sets near the one-particle basis set limit. It is found that post-MP2 ‘high-level corrections’ are treated adequately well using a combination of CCSD(F12*) with (aug-)cc-pVTZ-F12 basis sets on the one hand, and (T) extrapolated from conventional CCSD(T)/heavy-aug-cc-pV{D,T}Z on the other hand. Implications for earlier benchmarks on the larger S66×8 problem set in particular, and for accurate calculations on non-covalent interactions in general, are discussed. At a slight cost in accuracy, (T) can be considerably accelerated by using sano-V{D,T}Z+ basis sets, whereas half-counterpoise CCSD(F12*)(T)/cc-pVDZ-F12 offers the best compromise between accuracy and computational cost.

Several arguments suggest that the Planck scale could be the characteristic scale of curvature of momentum space. As other recent studies, we assume that the metric of momentum space determines the condition of on-shellness while the momentum space affine connection governs the form of the law of composition of momenta. We show that the possible choices of laws of composition of momenta are more numerous than the possible choices of affine connection on a momentum space. This motivates us to propose a new prescription for associating an affine connection to momentum composition, which we compare to the one most used in the recent literature. We find that the two prescriptions lead to the same picture of the so-called [Formula: see text]-momentum space, with de Sitter (dS) metric and [Formula: see text]-Poincaré connection. We then show that in the case of “proper dS momentum space”, with the dS metric and its Levi–Civita connection, the two prescriptions are inequivalent. Our novel prescription leads to a picture of proper dS momentum space which is DSR-relativistic and is characterized by a commutative law of composition of momenta, a possibility for which no explicit curved momentum space picture had been previously found. This momentum space can serve as laboratory for the exploration of the properties of DSR-relativistic theories which are not connected to group-manifold momentum spaces and Hopf algebras, and is a natural test case for the study of momentum spaces with commutative, and yet deformed, laws of composition of momenta.

Background: The ‘Primary Care SHOPping Intervention for Cardiovascular Disease Prevention’ (PCSHOP) trial tested the effectiveness and feasibility of a behavioural intervention to reduce saturated fat in food purchases. The intervention offered feedback from data collected through a supermarket loyalty card to supplement brief advice from a nurse. This qualitative study aimed to describe participants’ experiences of receiving this intervention. Methods: We conducted semi-structured, one-to-one, telephone interviews with participants from the PCSHOP trial. Interviews were audio-recorded and transcribed verbatim. We employed the one sheet of paper technique and a thematic analysis to develop high-level themes in NVivo software. Results: Twenty-four participants were interviewed (mean age: 63 years (SD 12)). They reported that the brief advice did not provide any new information but they welcomed the sense of accountability the nurse provided. The personalised shopping feedback and healthier swap suggestions provided novel information that challenged previously held beliefs about the saturated fat content of food purchases and encouraged some positive dietary changes. However, the taste preferences of the participant or other household members were a barrier to changing food shopping behaviours. Conclusion: Harnessing loyalty card data is a novel and acceptable method to offering personalised dietary feedback. Yet, issues on the suitability of the healthier swap suggestions limited the extent of dietary change. Trial registration: ISRCTN14279335. Registered 1 September 2017.

В современных стрессовых и негативных внешних экологических условиях растет число неуверенных в себе, эмоционально неустойчивых тревожных детей. В работах А.И.Захаровой, Н.В.Имеладзе, Л.М. Прихожановой говорится, что когда человек постоянно волнуется - возникает паника. Согласно анализу исследований многих авторов, детская тревога, с одной стороны, имеет психодинкамическую природу, с другой-является результатом социализации. По мнению психологов, у учащихся наблюдается высокий уровень тревожности в процессе обучения. В результате изучения данной проблемы установлено, что уровень тревожности и успеваемость ребенка тесно взаимосвязаны. Процесс приобщения детей, пришедших в школу, к процессу обучения тесно связан с процессом паники . In the current stressful and negative external environmental conditions, the number of insecure, emotionally unstable children with anxiety is growing. In the works of A.I. Zakharova, N.V. Imeladze, L.M. Prikhozhan, it is said that when a person is constantly agitated, panic occurs. According to the analysis of the research of many authors, child anxiety, on the one hand, has a psychodynamic nature, and on the other-is the result of socialization. According to psychologists, there is a high level of anxiety in students ' learning process. As a result of the study of this problem, it was found that the level of anxiety and the child's academic performance are closely related. The process of adaptation of children to the learning process is closely related to the panic process. However, the level of anxiety in lower-class students affects the learning process and learning outcomes.

This study aims to examine the laws of dowry money decoration that are common in the community. The innovation and soul of art that is channeled through décor of dowry money is proven to produce beautiful and unique works, so as to attract the attention and interest of the wider community. However, because to produce beautiful and unique works, a high level of creativity is needed, so not everyone can do it. On the one hand, this phenomenon opens up quite good business opportunities, but on the other hand, it should be watched out, because in some conditions it contains the practice of buying and selling currencies with nominal differences. Through this study, I would like to uncover the law of buying and selling practices decorating dowry money and decorating services. As I also intend to present an applicative solution for the community so that they can still channel their artistic talents without violating Shari’ah law.
