Published: September 2023

IntroductionSlovakia belongs among the countries with the highest cardiovascular mortality, nevertheless extensive data on the effectiveness of dyslipidaemia management is lacking. The aim of this study was to assess the implementation of European guidelines in the very high-risk population in Slovakia.Material and methodsWe retrospectively analysed anonymised LDL C values of patients at very high cardiovascular risk gathered between 2017 and 2019 from collaborating laboratory with nationwide reach. CV risk was based on patient’s ICD diagnoses. LDL C target values were based on the 2016ESC/EAS recommendations, as well as current recommendations from 2019. Patients diagnosed with ACS, stroke, or overall very high-risk CVD were selected.ResultsA total of 220 657 LDL-C test results from 72 039 patients were processed. Only 8 9% of patients with ACS attained target LDL-C in a follow-up test each year. 6-9% of patients had LDL-C levels ≥ 4.9 mmol/l. Only 9-10% of patients with stroke achieved target LDL-C levels, and 7-8% had levels ≥ 4.9 mmol/l. In the very high CV risk group, only 7% of patients achieved target levels, and 7-8% had extremely high LDL-C levels ≥ 4.9 mmol/l. With the ESC/EAS2019 recommendations only 2-3% of patients in each group achieved target levels each year.ConclusionsBased on our results, we found that over 90% of patients with very high CVD risk do not achieve target LDL-C levels. This percentage is even higher when implementing the 2019 guidelines. These patients remain at high risk of subsequent CVD events and would benefit significantly from intensified hypolipemic therapy.
Interpersonal differences in stress, coping, and satisfaction with life in the context of individual profiles of satisfaction and frustration of basic psychological needs
Authors: Barański Maciej , Poprawa Ryszard 
Published: September 2023

BackgroundBasic psychological need theory has identified three basic needs: autonomy, competence, and relatedness. Need satisfaction is necessary for development and well-being, while need frustration can lead to maladaptive functioning. The study investi-gated the significance of individual profiles of basic psychological need satisfaction and frustration in experiencing stress, coping, and satisfaction with life.Participants and procedureParticipants (N = 622, Mage = 22.22 ± 4.30) completed the Basic Psychological Need Satisfaction and Frustration Scale, Per-ceived Stress Scale, Stress Appraisal Questionnaire, COPE Inventory, and Satisfaction with Life Scale. We performed explor-atory factor analysis to identify coping styles, latent profile analysis to distinguish groups with specific need profiles, and MANOVA to demonstrate differences between these groups.ResultsFive coping styles were identified: (1) problem-focused, (2) emotion-focused, (3) meaning-focused, (4) escape-avoidance, and (5) religious. The following groups of individuals characterized by specific profiles of basic psychological need satisfaction and frustration were distinguished: (1) mainly low satisfaction and high frustration of relatedness; (2) high satisfaction and low frustration of all basic needs; (3) low satisfaction and high frustration of all basic needs; (4) average satisfaction and frustration of all basic needs; (5) mainly low satisfaction and high frustration of competence. These groups significantly differ in perceived stress, coping styles, and life satisfaction.ConclusionsIndividuals with profile 3 were the most stressed and tend to use escape-avoidance coping style. Participants with profile 2 coped using a problem-focused style and had higher life satisfaction. These findings indicate that a person-centered ap-proach leads to a better understanding of experiencing stress and coping.
An extraction method for nitrogen isotope measurement of ammonium in a low-concentration environment

Published: September 2023

Abstract. Ammonia (NH3) participates in the nucleation and growth
of aerosols and thus plays a major role in atmospheric transparency,
pollution, health, and climate-related issues. Understanding its emission
sources through nitrogen stable isotopes is therefore a major focus of
current work to mitigate the adverse effects of aerosol formation. Since ice
cores can preserve the past chemical composition of the atmosphere for
centuries, they are a top tool of choice for understanding past NH3
emissions through ammonium (NH4+), the form of NH3 archived
in ice. However, the remote or high-altitude sites where glaciers and ice
sheets are typically localized have relatively low fluxes of atmospheric
NH4+ deposition, which makes ice core samples very sensitive to
laboratory NH3 contamination. As a result, accurate techniques for
identifying and tracking NH3 emissions through concentration and
isotopic measurements are highly sought to constrain uncertainties in
NH3 emission inventories and atmospheric reactivity unknowns. Here, we
describe a solid-phase extraction method for NH4+ samples of low
concentration that limits external contamination and produces precise
isotopic results. By limiting NH3atm exposure with a scavenging fume
hood and concentrating the targeted NH4+ through ion exchange
resin, we successfully achieve isotopic analysis of 50 nmol NH4+
samples with a 0.6 ‰ standard deviation. This extraction
method is applied to an alpine glacier ice core from Col du Dôme,
Mont Blanc, where we successfully demonstrate the analytical approach
through the analysis of two replicate 8 m water equivalent ice cores
representing 4 years of accumulation with a reproducibility of ±2.1 ‰. Applying this methodology to other ice cores in
alpine and polar environments will open new opportunities for understanding
past changes in NH3 emissions and atmospheric chemistry.
Understanding representations of uncertainty, an eye-tracking study – Part 2: The effect of expertise

Published: September 2023

Abstract. As the ability to make predictions regarding uncertainty information
representing natural hazards increases, an important question for those
designing and communicating hazard forecasts is how visualizations of
uncertainty influence understanding amongst the intended, potentially
varied, target audiences. End-users have a wide range of differing expertise
and backgrounds, possibly influencing the decision-making process they
undertake for a given forecast presentation. Our previous, Part 1 study
(Mulder et al., 2023) examined how the presentation of uncertainty
information influenced end-user decision making. Here, we shift the focus to
examine the decisions and reactions of participants with differing areas of expertise
(meteorology, psychology, and graphic-communication students) when presented
with varied hypothetical forecast representations (boxplot, fan plot, or
spaghetti plot with and without median lines) using the same eye-tracking
methods and experiments. Participants made decisions about a fictional
scenario involving the choices between ships of different sizes in the face
of varying ice thickness forecasts. Eye movements to the graph area and key
and how they changed over time (early, intermediate, and later viewing
periods) were examined. More fixations (maintained gaze on one location)
and more fixation time were spent on the graph and key during early and
intermediate periods of viewing, particularly for boxplots and fan plots.
The inclusion of median lines led to less fixations being made on all graph
types during early and intermediate viewing periods. No difference in eye
movement behaviour was found due to expertise; however, those with greater
expertise were more accurate in their decisions, particularly during more
difficult scenarios. Where scientific producers seek to draw users to the
central estimate, an anchoring line can significantly reduce cognitive load,
leading both experts and non-experts to make more rational decisions. When
asking users to consider extreme scenarios or uncertainty, different prior
expertise can lead to significantly different cognitive loads for processing
information, with an impact on one's ability to make appropriate decisions.
Understanding representations of uncertainty, an eye-tracking study – Part 1: The effect of anchoring

Published: September 2023

Abstract. Geoscience communicators must think carefully about how
uncertainty is represented and how users may interpret these
representations. Doing so will help communicate risk more effectively, which
can elicit appropriate responses. Communication of uncertainty is not just a
geosciences problem; recently, communication of uncertainty has come to the
forefront over the course of the COVID-19 pandemic, but the lessons learned
from communication during the pandemic can be adopted across geosciences as
well. To test interpretations of environmental forecasts with uncertainty,
a decision task survey was administered to 65 participants who saw different
hypothetical forecast representations common to presentations of
environmental data and forecasts: deterministic, spaghetti plot with and
without a median line, fan plot with and without a median line, and box plot
with and without a median line. While participants completed the survey,
their eye movements were monitored with eye-tracking software. Participants'
eye movements were anchored to the median line, not focusing on possible
extreme values to the same extent as when no median line was present.
Additionally, participants largely correctly interpreted extreme values from
the spaghetti and fan plots, but misinterpreted extreme values from the box
plot, perhaps because participants spent little time fixating on the key.
These results suggest that anchoring lines, such as median lines, should
only be used where users should be guided to particular values and where
extreme values are not as important in data interpretation. Additionally,
fan or spaghetti plots should be considered instead of box plots to reduce
misinterpretation of extreme values. Further study on the role of expertise
and the change in eye movements across the graph area and key is explored in more detail in the companion paper to this study (Williams et al., 2023; hereafter Part 2).
El Niño–Southern Oscillation (ENSO)-driven hypersedimentation in the Poechos Reservoir, northern Peru

Published: September 2023

Abstract. Although extreme El Niño events (EENEs) have always impacted
hydrological anomalies and sediment transport in South America, their
intensification by global warming and their association with changes in
human activities and land cover after humid periods may lead to the
acceleration of sediment transfers in river systems and dam reservoirs. This
situation may threaten soil and water resources in arid and semiarid regions
highly dependent on water originating from large dams. In this study, we
investigated the sediment sequence accumulated in the Poechos Reservoir
(northern Peru) and provided a retrospective reconstruction of the
interactions of El Niño–Southern Oscillation (ENSO), agricultural
practices and vegetation cover changes with sediment dynamics (1978–2019). To
this end, a sediment core was dated and characterized by physical and
chemical analyses (e.g., scanner tomography, X-ray fluorescence, particle
size analysis) to estimate the evolution of sedimentation rates and
changes in sediment sources during the last 5 decades. Sediment tracing results indicated the occurrence of changes in sediment
sources associated with positive and negative phases of the Eastern Pacific
index with a greater contribution of the lowland dry-forest area in
comparison to that of the Andean area to sediment during the El Niño
events (mean contribution of 76 %; up to 90 % during the coastal El
Niño events (CENEs) of 2016–2017). This source contribution was mostly
controlled by the stationary rainfall occurring during the EENEs in the lowland dry-forest area characterized by a low vegetation cover. Overall, after an extreme phase of ENSO, like after the
EENE 1982–1983, the normal discharges and persistent sediment supplies from
the middle- and upper-catchment parts led to river aggradation and the
storage of substantial amounts of sediment in alluvial plains. In the
absence of a significant EENE between 1983 and 1997, the large volume of
sediment stored in the alluvial plains was exported by the EENE 1997–1998
resulting in an increase in sedimentation rate of 140 % after 1997 with
a significant aggradation of the deltaic zone of the reservoir. In addition
to the impact of extreme climate events on sediment dynamics, the
development of agriculture along the riverine system after an extreme phase
of ENSO increased the availability of sediments in the main channel of the
rivers, easily transported by the next EENE. This study suggests that
intensification of human activities associated with a higher frequency of
extreme rainfall events amplified the quantity of sediment transported by
the river system, which will significantly decrease the lifespan of the
reservoir, which is essential to meeting the freshwater demands of the farmers and the
populations living in this arid and semiarid region.
Cross-scale perspective on the Opalinus Clay: insights from the GeomInt2 project
Authors: Cajuhi Tuanny , Maßmann Jobst , Ziefle Gesa , Nagel Thomas , Yoshioka Keita 
Published: September 2023

Abstract. Understanding complex systems, such as radioactive waste repositories,
involves the study of cross-scale coupled processes. We discuss some important concepts and their mutual interactions for interpreting such
systems based on complementary model-based analyses at various scales (Fig. 1). These points are linked with practical examples that pertain to the hydromechanical effects and cracking of the Opalinus Clay. In the
Federal Ministry of Education and Research (BMBF)-funded project “Geomechanical integrity of host and barrier rocks – experiment, modeling and analysis of discontinuities (GeomInt2)” (Cajuhi et al., 2023a in Kolditz et al., 2023), these effects have been investigated experimentally and numerically, both at laboratory and at field scales. While interpretation influences the conceptualization of experimental and/or numerical models, a clear goal definition is required to delimit the complex system. One goal statement in the context of this contribution is to explain the formation of drying cracks, where essential processes and boundary conditions must be pinned down. Monitoring data are critical for determining the correlation between experimental and numerical setups. This is achieved by quantifying and questioning the assignability of information derived from data obtained from core samples tested in the laboratory to field-scale analyses. Numerical modeling can help validate model ideas by reproducing measured data and making predictions beyond the experimentally observable range. The detailed information gained from these studies can be used for interpretation and simplification. In a recent study, we used the phase-field approach to model the formation and evolution of cracks and stated the conditions under which desiccation cracks will develop at the field scale as well as how deep they propagate into the rock (Cajuhi et al., 2023b). This information about the near field can be used to determine how detailed repository far-field models must be and, for example, whether cracks need to be taken into account. Consequently, the cross-scale study of complex systems can lead to more robust analysis results.
AREHS: effects of changing boundary conditions on the development of hydrogeological systems: numerical long-term modelling considering thermal–hydraulic–mechanical (–chemical) coupled effects

Abstract. The objective of the AREHS project, funded by BASE (FKZ 4719F10402), is to
model the effects of changing external boundary conditions on the
hydrogeologically relevant parameters and effects (e.g. hydraulic
permeability, porosity, migration pathways, fluid availability, hydraulic
gradients) of a generic geological repository in Germany in all three
potential host rocks (clay, salt, and crystalline rocks) in its hydrogeological setting. Special attention is paid to the cyclic mechanical
loading due to glaciation events. This results in stress changes (M – mechanical processes) as well as induced temperature effects (T – thermal processes) due to permafrost and warm periods. Since the thermal, hydraulic (H – hydraulic processes), and mechanical processes are strongly coupled, they have to be covered by state-of-the-art coupled thermal–hydraulic–mechanical (THM) (C) modelling. The presentation consists of a (a) presentation of important findings for all three host rock types and a (b) presentation of the overall workflow. Complex, time-varying boundary conditions have been formulated for modelling glacial cycles. Investigating the effects of these boundary conditions with THM simulation reveals a variety of coupling effects. To conduct the complex modelling workflow for claystone and salt rock
effectively, an automated workflow was developed and tested. It handles the
transformation from a simulator-independent geological model to a numerical
model specific to the simulator. This contains a suitable finite-element
mesh and a parameterization of the fully coupled or optionally isolated
thermal–hydraulic–mechanical processes, which are implemented and executed in the OpenGeoSys simulator. Simulation results are presented for selected physical quantities at characteristic local and temporal points with respect to the position of a migrating glacier. The investigation results are reproducible
through full automation, container deployment, and a continuous integration
process running on a GitLab instance (see Fig. 1a). To simulate the response of a fractured crystalline rock mass to THM impacts, the explicit integration of the fracture network in numerical models is necessary. The workflow couples the distinct element method (DEM) software “3DEC” and the discrete fracture network (DFN) software “DFN.Lab” automatically (Fig. 1b).

Published: September 2023

Abstract. In a deep geological repository for radioactive waste,
anaerobic corrosion of various metals lead to the formation of hydrogen. In
Switzerland, the implementor (i.e., Nagra) is commissioned to describe and evaluate
safety-relevant processes related to gas that can affect the long-term
evolution of low- and intermediate-level waste (L/ILW), high-level waste
(HLW), and combined L/ILW and HLW repositories. Key tasks include the
evaluation of gas and radionuclide release pathways and the pressure and
temperature evolution in the repository using multiphase and
multicomponent flow and transport models. The Swiss repository design foresees the installation of multiple seals
(engineered barriers) in the repository: (i) the V1 seals next to the waste
emplacement caverns and tunnels, (ii) the V2 seals located in the access tunnels
toward the emplacement caverns and tunnels, and (iii) the V3 seals positioned in
the shafts of the repository. These seals are designed to satisfy a wide
range of requirements, including requirements related to the hydraulic
evolution of the repository and the associated transport of gas, water, and
radionuclides. A modeling workflow is currently being developed that integrates modeling
performed both at the repository scale using site-specific models and at the
component scale using semi-generic models. The repository-scale models are
built to assess the thermo-hydraulic evolution in the entire repository,
whereas the component-scale models allow for more detailed evaluations of
the gas and water flows in key structures of the repository, such as the V1,
V2, and V3 seals as well as the emplacement caverns and tunnels. This conference
contribution describes the methodology and workflow developed to integrate
these models, with a focus on the development and functionality of the
component-scale models.
