H2O coordination in macropa complexes of f elements (Ac, La, Lu): feasibility of the 11th coordination site
Authors: Kovács Attila , Varga Zoltán 
Published: January 2021

AbstractThe feasibility of an additional ligand coordination at the 11th coordination site of actinium, lanthanum, and lutetium ions in 10-fold coordinated macropa complexes has been studied by means of density functional theory calculations. The study covered the two main macropa conformers, Δ(δλδ)(δλδ) and Δ(λδλ)(λδλ), favoured by larger (Ac3+, La3+) and smaller (Lu3+) ions, respectively. At the molecular level, the coordination of H2O is the most favourable to the largest Ac3+while only slightly less to La3+. Protonation of the picoline arms enhances the coordination by shifting the metal ion closer to the open site of the ligand. The choice of macropa conformer has only a slight influence on the strength and bonding properties of the H2O coordination. Aqueous solution environment decreases considerably the energy gain of H2O coordination at the 11th coordination site.
Can happiness measures be calibrated?
Authors: Ingelström Mats , van der Deijl Willem 
Published: January 2021

AbstractMeasures of happiness are increasingly being used throughout the social sciences. While these measures have attracted numerous types of criticisms, a crucial aspect of these measures has been left largely unexplored—their calibration. Using Eran Tal’s recently developed notion of calibration we argue first that the prospect of continued calibration of happiness measures is crucial for the science of happiness, and second, that continued calibration of happiness measures faces a particular problem—The Two Unknowns Problem. The Two Unknowns Problem relies on the claim that individuals are necessarily a part of the measurement apparatus in first person measures of happiness, and the claim that we have no reason to believe that the evaluation standards people employ are invariant across individuals and time. We argue that calibrating happiness measures therefore involves solving an equation with two unknowns—an individual’s degree of happiness, and their evaluation standards—which is, generally, not possible. Third, we consider two possible escape routes from this problem and we suggest that the most promising route requires yet unexplored empirical and theoretical work on linking happiness to behavioral or neural evidence.
Financial Resilience, Income Dependence and Organisational Survival in UK Charities
Authors: Green Elizabeth , Ritchie Felix , Bradley Peter , Parry Glenn 
Published: January 2021

AbstractThe financial well-being of the charity sector has important social implications. Numerous studies have analysed whether the concentration of income in a few sources increases financial vulnerability. However, few studies have systematically considered whether the type of income (grants, donation, fund-raising activities) affects the survival prospects of the charity. We extend the literature by (a) explicitly modelling the composition of sources of income, (b) allowing for short-term volatility as well as long-term survival and (c) testing alternative specifications in a nested form. We show that the usual association between income concentration per se and financial vulnerability is a specification error. Greater vulnerability is associated with dependence on grant funding, not overall concentration. Previous studies showing that concentration of income per se is problematic are picking up a proxy effect. We also show that the volatility of income streams may be an important factor in the survival of charities, but that this also varies between income sources.

Published: January 2021

AbstractInformal volunteering is seen as an important indicator of social relations and community life. We therefore investigate the impact of various socialization practices on informal volunteering, being small helping behaviours outside of organizations for people outside the household. From theoretical notions on socialization, we hypothesize that experiencing extensive prosocial socialization practices promotes informal volunteering. We examine socialization processes of both modelling and encouragement and consider two socializing agents: parents and partners. We test our expectations employing the sixth wave of the Family Survey Dutch Population (N = 2464) that included unique measures on socialization as well as informal volunteering and holds important control variables. Our results indicated that parental modelling, partner modelling and partner encouragement were all positively related to informal volunteering, but that parental encouragement was not significantly related to informal volunteering. Our paper, thus, underscores that socialization practices are relevant in nurturing social relations and community life.
Spectrum of [18F]FDG-PET/CT Findings in Benign Lymph Node Pathology
Authors: Zeman Merissa N. , Green Clare , Akin Esma A. 
Published: January 2021

AbstractDiffuse lymphadenopathy has a long differential diagnosis that includes both malignant and benign causes. As part of the lymphadenopathy work-up, many patients undergo [18F]FDG-PET/CT for purposes of ruling out malignancy. FDG-avid lymph nodes, however, are not specific for malignancy. This review will illustrate the spectrum of nodal findings on FDG-PET/CT with correlation to other cross-sectional imaging and clinical history in patients with representative infectious, inflammatory, and benign lymphoproliferative disorders. These findings are important for the nuclear medicine radiologist to understand, as they can represent common pitfalls in the work-up of lymphadenopathy. While FDG-PET/CT may be limited in ascertaining a definitive diagnosis in a disease process as the cause of lymphadenopathy, it can help to narrow this differential and rule out certain diseases in the correct clinical context.

Abstract
Purpose
The aim of this study was to estimate the impact of lake disappearance, groundwater table fluctuations, and some aspects of human pressure on stages of soil cover development in the catchment of Lake Rakutowskie.

Materials and methods
Research was conducted in soil chronosequence composed of eight soil profiles located in 785-m-long transect. Soils were sampled every 10 cm. Physical and chemical properties were determined with the use of disturbed and undisturbed samples. Radiocarbon dates were obtained for the bottom part of peat in each soil profile. The mineral composition of selected soil samples was determined using the X-ray diffraction (XRD) method. Additionally, the hydrological conditions were continuously monitored from July 27, 2013 to September 23, 2014.

Results and discussion
An increased rate of shallow lakes overgrowth and final disappearance is a commonly observed process in the European lowlands. This paper presents and discusses the influence of changes in the range of the Lake Rakutowskie wetlands complex (central Poland) and water level fluctuations on soil cover transformation in the immediate vicinity of the lake. Five major phases of soil cover development (from Subaquatic Histosols (Limnic) to Hypereutric Regosol (Drainic, Humic)) were hypothetically reconstructed based on detailed studies of soil physical and chemical properties, mineral composition, water level fluctuations, and radiocarbon dating. The degree of peat decomposition in the studied profiles increased with the distance from the contemporary lake surface. Along with the progressive dehydration and mineralization of organic soils, their physical and chemical properties deteriorated, which is visible, e.g., in soil structure, and mineral and chemical composition (especially TOC and TN). Obtained radiocarbon ages of selected samples indicate that the oldest peat layers developed about 5856 cal BCE (6970 ± 70 14C BP), while the youngest were deposited about 1074 cal CE (980 ± 40 14C BP)–1573 cal CE (300 ± 35 14C BP). Hydrological studies indicate a progressive process of lake disappearance.

Conclusions
The process of soil cover transforming of the studied area takes place relatively quick, mainly recently due to the influence of human activity. Based on these results, it can be predicted that the lake will most likely disappear in a relatively short time, and the soil cover will be entirely in the fifth phase (P5) of evolution.
Urban soil microbial community and microbial-related carbon storage are severely limited by sealing
Authors: Pereira Marlon Correa , O’Riordan Roisin , Stevens Carly 
Published: January 2021

Abstract
Purpose
Urbanisation causes changes in land use, from natural or rural to urban, leading to the sealing of soil and the replacement of vegetation by buildings, roads and pavements. The sealing process impacts soil properties and services and can lead to negative consequences for microbial attributes and processes in soil. At present, information about the microbial community following soil sealing is limited. As such, we investigated how changes in soil physical and chemical properties caused by sealing affect the soil microbial community and soil ecosystem services.

Material and methods
Soils were sampled beneath impervious pavements (sealed) and from adjacent pervious greenspace areas (unsealed). Soil properties (total C, total N, C:N ratio and water content) and microbial attributes (microbial biomass C, N-mineralisation and phospholipid fatty acids—PLFA) were measured and correlated.

Results and discussion
A reduction of total C, total N, and water content were observed in sealed soil, whilst the C:N ratio increased. Sealed soil also presented a reduction in microbial attributes, with low N-mineralisation revealing suppressed microbial activity. PLFA data presented positive correlations with total C, total N and water content, suggesting that the microbial community may be reduced in sealed soil as a response to soil properties. Furthermore, fungal:bacterial and gram-positive:gram-negative bacterial ratios were lower in sealed soil indicating degradation in C sequestration and a consequential effect on C storage.

Conclusions
Sealing causes notable changes in soil properties leading to subsequent impacts upon the microbial community and the reduction of microbial activity and soil C storage potential.

Published: January 2021

AbstractThe major aim of this research was to investigate the effect of ozone treatment on the energy metabolism in raspberry fruit during storage at room temperature. Raspberries were ozonated with an ozone concentration of 8–10 mg L−1, for 30 min, every 12 h of storage at room temperature for 72 h. The results indicated that ozone treatment significantly enhanced the activities of mitochondrial respiratory enzymes, such as succinate dehydrogenase, cytochrome C oxidase, and H+-ATPase, which contributed to maintain the high level of ATP and energy charge in fruit during storage. Moreover, the energy metabolism in mitochondria was closely correlated with the antioxidant potential of raspberry fruit. This study has given an experimental evidence that ozonation procedure in proposed process conditions significantly affects the mitochondrial respiratory system leading to maintain the high quality of the fruit over a long period of storage at room temperature.
Peer network Status and Depressive Symptoms Among Early Adolescents: Testing the Mediating Effects of Metaperception and Loneliness

Published: January 2021

AbstractPrevious research shows that deficits in social relationships increase the risk of depression. This study tests the hypothesis that among early adolescents, their status in their peer network (likeability/dislikeability) will be associated with depressive symptoms but only indirectly, through the subjective perception of this status (positive/negative metaperception) and loneliness (feeling of social isolation). Data were collected using sociometric methods and self-report scales from 388 students aged 12–13. Path analysis was applied to verify the hypothesized relationships between the study variables. The findings indicate that: (1) status in the peer network and its perception affect depressive symptoms only indirectly, through loneliness; (2) depressive symptoms depend directly on loneliness alone; (3) status in the peer network does not directly translate into loneliness—its effect is mediated by metaperception; (4) the negative dimension of the peer network status indirectly affects both loneliness and depressive symptoms more strongly than the positive one. The main limitation of the research is its cross-sectional design, which precludes definite conclusions about the direction of the relationships observed. The results obtained help to clarify the complex mechanisms through which objective status in the peer network, its subjective perception and feelings of loneliness contribute to the severity of depressive symptoms among early adolescents. On the practical side, the findings highlight the importance of developing and implementing interventions targeting both the objective and subjective aspects of social relations for the prevention of depression in this age group.

AbstractGroundwater is the major source for resident drinking, industrial development, and agricultural irrigation in the Huai River Basin (HRB). With the development of industry and agriculture, exploitation of the deep groundwater increases dramatically in the HRB in recent years. Therefore, analysis and evaluation the renewability of the deep groundwater in the HRB is critical. In our study, a total of 390 groundwater samples were collected along four profiles in 35 cities and counties within the HRB to obtain their hydrochemical characteristics and isotopic data. Based on the isotopic data of these samples, three deep groundwater subsystems: the Shaying River System, the Guohe River System, and the Ancient Yellow River System were identified. The further comparison indicates that the deep and shallow groundwater systems of Guohe River System and Shaying River System have good differentiation. While, the connection of deep and shallow aquifer of Ancient Yellow River System is strong. According to the calculation results based on the combination of stable isotopes and water chemistry, the renewable ability of deep groundwater of Ancient Yellow River, Shaying river, and Guo river are 36%, 22%, and 12%, respectively, which implies faster renewal rate and greater exploitation potential.
Herbicide stress-induced DNA methylation changes in two Zea mays inbred lines differing in Roundup® resistance

Published: January 2021

AbstractDNA methylation plays a crucial role in the regulation of gene expression, activity of transposable elements, defense against foreign DNA, and inheritance of specific gene expression patterns. The link between stress exposure and sequence-specific changes in DNA methylation was hypothetical until it was shown that stresses can induce changes in the gene expression through hypomethylation or hypermethylation of DNA. To detect changes in DNA methylation under herbicide stress in two local Zea mays inbred lines exhibiting differential susceptibility to Roundup®, the methylation-sensitive amplified polymorphism (MSAP) technique was used. The overall DNA methylation levels were determined at approximately 60% for both tested lines. The most significant changes were observed for the more sensitive Z. mays line, where 6 h after the herbicide application, a large increase in the level of DNA methylation (attributed to the increase in fully methylated bands (18.65%)) was noted. DNA sequencing revealed that changes in DNA methylation profiles occurred in genes encoding heat shock proteins, membrane proteins, transporters, kinases, lipases, methyltransferases, zinc-finger proteins, cytochromes, and transposons. Herbicide stress-induced changes depended on the Z. mays variety, and the large increase in DNA methylation level in the sensitive line resulted in a lower ability to cope with stress conditions.
Waiting time before NDT of welded offshore steel grades under consideration of delayed hydrogen-assisted cracking
Authors: Wilhelm Eugen , Mente Tobias , Rhode Michael 
Published: January 2021

AbstractOffshore wind turbines (OWT) are a major goal of the energy strategy of Germany encompassing the increase of the installed wind power. OWT components are manufactured from welded steel plates with thicknesses up to 200 mm. The underlying standards and technical recommendations for construction of OWTs encompass specifications of so-called minimum waiting time (MWT) before non-destructive testing of the weld joints is allowed. Reason is the increased risk of time-delayed hydrogen-assisted cold cracking as hydrogen diffusion is very slow due to the very thick plates. The strict consideration of those long MWT up to 48 h during the construction of OWTs leads to significant financial burden (like disproportionately high costs for installer ships as well as storage problems (onshore)). In this study, weld joints made of S355 ML were examined in comparison with the offshore steel grade S460 G2+M. The aim was to optimize, i.e., reduce, the MWT before NDT considering varied heat input, hydrogen concentration and using self-restraint weld tests. This would significantly reduce the manufacturing time and costs of OWT construction. To quantify the necessary delay time until hydrogen-assisted cold cracks appear, acoustic emission analysis was applied directly after welding for at least 48 h.

Abstract
Aims/Introduction
The relationship between urinary excretion rate of glucose (UEGL) and uric acid (UA) metabolism in adults with type 2 diabetes (T2D) remains unclear to date. This study aimed to investigate the relationships of UEGL with serum UA (SUA), urinary excretion rate of uric acid (UEUA), and renal clearance of uric acid (CLUA) in adults with T2D. We hypothesised that high UEGL increases UA excretion, which in turn leads to lower SUA.

Materials and methods
This was a cross-sectional study of 635 inpatients with T2D recruited between 2018 and 2019. The relationships of UEGL with UEUA, CLUA, and hyperuricaemia were assessed using analysis of covariance and multivariate regression analysis.

Results
Patients in the higher quartile of UEGL tended to have lower SUA levels than those in the lower quartile. In contrast, patients in the higher quartile of UEGL tended to have higher CLUA (p for trend < 0.0001), and a similar trend was observed for UEUA. In adjusted multivariable linear regression model, UEGL was negatively correlated with SUA (β = − 0.023, 95% CI − 0.034 to − 0.013, p < 0.0001). However, positive correlations of UEGL with UEUA (β = 0.046, 95% CI 0.018–0.074, p = 0.001) and CLUA (β = 0.063, 95% CI 0.042–0.085, p < 0.0001) were found. Furthermore, consistent significant inverse associations were observed between quartiles of UEGL and hyperuricaemia in the adjusted multivariate logistic regression model.

Conclusions
A high UEGL level was positively correlated with UEUA and CLUA. Moreover, it was inversely associated with SUA level, and a consistently increased UEGL level reduced the risk of hyperuricaemia in patients with T2D.

Published: January 2021

Introduction The number of children with asthma has increased significantly in China. In recent years, there has been a steady increase in outpatient visits of children with asthma, attributed to poor air quality and environmental pollution reported regionally and at our institution. This study aimed to assess the association between air pollution and the number of outpatient visits of children with asthma in Xi’an, the largest city in northwest China. Methods We searched the database of the largest children’s hospital in Xi’an for related information from 2014 to 2018 and then acquired data on air pollution, including the daily average concentrations of fine particles (PM2.5), inhalable particles (PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2) of that same time period. Time-series generalized additive models were used to analyze the relationships. Results Our results revealed that air pollution was very serious in Xi’an, with elevated average concentrations of PM2.5, PM10, and NO2 from 2015 to 2018. The relative risk of outpatient visits due to asthma associated with PM2.5, PM10, and SO2 pollution rose significantly and reached 1.11 (1.02–1.21), 1.25 (1.01–1.55), and 1.71 (1.31–2.25), respectively, when there was a 10 ug·m-3 increase in concentration, during a lag of 21 d. Conclusions A high concentration of particulate matter (PM2.5 and PM10) was the prominent feature of air pollution in Xi’an. Exposure to air pollutant (PM2.5, PM10, SO2) was positively associated with an increased risk of children’s outpatient visits for asthma in Xi’an.
The Democratic Impact of Strengthening European Fundamental Rights in the Digital Age: The Example of Privacy Protection
Authors: Seubert Sandra , Becker Carlos 
Published: January 2021

AbstractIn times of digital pervasion of everyday life, the EU has strengthened a normative idea of European fundamental rights, especially by referring to a strong notion of privacy protection. A normative corridor is evolving with the “right to privacy” at its heart, a right that will be instrumental in shaping the European legal architecture’s future structure. In this Article we argue that the constitutional protection of privacy rights is not only of individual relevance but also of major democratic significance: it protects the integrity of the communication structures that underpin democratic self-determination. The debate on privacy protection, however, often lacks a democratic understanding of privacy and misses its public value. Following an interactionist understanding of privacy and a discourse-theoretical model of democracy, our argument puts forward a conceptual link between privacy and the idea of communicative freedom. From this perspective, the substantiation of a European fundamental right to privacy can be seen as a possible contribution to promoting European democracy in general.
