This study was undertaken to compare biogas production by maize and sorghum stalks for house hold energy supply in Pankshin local government area of Plateau state. An experimental research design was used. The experimental procedure included the growth of maize and sorghum stalks for two months (60 days) the stalks were selected and harvested while still succulents. The stalks were washed, cut into pieces using clean knives, pounded into pastes using mortar and pestles. An empty metal bucket with known weight was used, the pastes of each was weight and equal number of each bucket was put inside each digester accordingly from the top. The top was then sealed with super glue and the digesters were each painted with black oil paint. As a result of the size and volume of the digesters, the set up stayed for 14 days and being monitored daily. Findings indicate that for the Maize stalk there was no gas generated in day one as such the Bunsen burner did not burn. It burns for 50 seconds in day two, 1.5 minutes in day three and it rises steadily to 4 minutes in day eight. Then it started dropping to 3.5 minutes in day nine, 2.7 minutes in day ten, then it drops steadily to 0. 00 minute in day fifteen. For the Sorghum Stalk, days one and two no gas was generated as such the Bunsen burner did not burn. It burns for 1 minute in day three, 1.5 minutes in day four, then it rises steadily to 2.2 minutes for days 7 and 8 then to 2 minutes in day 9 then it started falling steadily to 0.00 minute in days 14 and 15. This implies that energy in form of biogas can be generated from maize and sorghum stalks. Exploring this can meet the increasing energy of man. Based on the results it was recommended amongst others the study can also be replicated with other varieties of common grass using standardized digesters. This is because grass is a weed and do not have other economic value like stalks from food crops. It was concluded that energy in form of biogas can be generated from maize and sorghum stalks. Exploring this can meet the increasing energy need of man. It is recommended that; the study can be carried out with the stalk of other crops such as rice, millet, cow pea and others.

Published: August 2023

This research provides clear perspective with broad spectrum on the pro-environmental behavior (PEB) of learners. It sought to determine the level of awareness, attitudes, intention, motivation, environmental social interaction, environmental education and green behavior of learners, and the significant relationship and significant difference among the variables. The researcher utilized the descriptive-qualitative survey method; through the use of a questionnaire backed up with Key Informant Interview (KII) and triangulated by Focus Group Discussion (FGD). CADMIACA, the model of this research, are from the theories of Comprehensive Action Determination Model (CADM) Motivational, Interpersonal ones (MI) and the Action Competence Approach (ACA). For the empirically causal relationship among variables, structural equation methodology (SEM) was initiated. The study included 384 learners from junior and senior high school of NDDU-IBED Lagao, General Santos City, school year 2017-2018. Overall, there is no significant difference on the PEB of junior and senior high school learners; they had a moderate energy-saving behavior and high level of environmental education. On the other hand, there is a significant difference in the attitude and global warming of students. Another study is recommended, using other respondents from a subdivision or barangay to determine whether social status might affect the totality of PEB of an individual.

Nitrogen oxides emissions from selected cities in North America, Europe, and East Asia observed by the TROPOspheric Monitoring Instrument (TROPOMI) before and after the COVID-19 pandemic
Authors: Lonsdale Chantelle R. , Sun Kang
Published: August 2023

Abstract. Nitrogen oxides (NOx=NO+NO2) emissions are estimated in three regions in the Northern Hemisphere,
generally located in North America, Europe, and East Asia, by calculating the directional derivatives of NO2 column amounts observed by
the TROPOspheric Monitoring Instrument (TROPOMI) with respect to the horizontal wind vectors. We present monthly averaged emissions from 1 May 2018 to 31 January 2023 to
capture variations before and after the COVID-19 pandemic. We focus on a diverse collection of 54 cities, 18 in each region. A spatial resolution of
0.04∘ resolves intracity emission variations and reveals NOx emission hotspots at city cores, industrial areas, and sea
ports. For each selected city, post-COVID-19 changes in NOx emissions are estimated by comparing monthly and annually averaged
values to the pre-COVID-19 year of 2019. While emission reductions are initially found during the first outbreak of COVID-19 in early 2020 in most
cities, the cities' paths diverge afterwards. We group the selected cities into four clusters according to their normalized annual NOx
emissions in 2019–2022 using an unsupervised learning algorithm. All but one of the selected North American cities fall into cluster 1 characterized by
weak emission reduction in 2020 (−7 % relative to 2019) and an increase in 2022 by +5 %. Cluster 2 contains mostly European cities and is
characterized by the largest reduction in 2020 (−31 %), whereas the selected East Asian cities generally fall into clusters 3 and 4, with the
largest impacts in 2022 (−25 % and −37 %). This directional derivative approach has been implemented in object-oriented, open-source Python and
is available publicly for high-resolution and low-latency emission estimation for different regions, atmospheric species, and satellite instruments.

Published: August 2023

Abstract. Polar nephelometers provide in situ measurements of aerosol angular light scattering and play an essential role in validating numerically calculated phase functions or inversion algorithms used in space-borne and land-based aerosol remote sensing. In this study, we present a prototype of a new polar nephelometer called uNeph. The instrument is designed to measure the phase function, F11, and polarized phase function, -F12/F11, over the scattering range of around 5 to 175∘, with an angular resolution of 1∘ at a wavelength of 532 nm. In this work, we present details of the data processing procedures and instrument calibration approaches. uNeph was validated in a laboratory setting using monodisperse polystyrene latex (PSL) and di-ethyl-hexyl-sebacate (DEHS) aerosol particles over a variety of sizes ranging from 200 to 800 nm. An error model was developed, and the level of agreement between the uNeph measurements and Mie theory was found to be consistent within the uncertainties in the measurements and the uncertainties in the input parameters for the theoretical calculations. The estimated measurement errors were between 5 % and 10 % (relative) for F11 and smaller than ∼ 0.1 (absolute) for -F12/F11. Additionally, by applying the Generalized Retrieval of Aerosol and Surface Properties (GRASP) inversion algorithm to the measurements conducted with broad unimodal DEHS aerosol particles, the volume concentration, size distribution, and refractive index of the ensemble of aerosol particles were accurately retrieved. This paper demonstrates that the uNeph prototype can be used to conduct accurate measurements of aerosol phase function and polarized phase function and to retrieve aerosol properties through inversion algorithms.

Abstract. Multiphase chemistry is an important pathway for the formation of secondary organic aerosols (SOAs) in the atmosphere. In this study, an indoor 2 m3 Teflon chamber system (Aerosol multIphase chemistry Research chamber, AIR) was developed and characterized to specifically simulate atmospheric multiphase chemistry processes. The temperature and humidity controls, diurnal variation simulation, and seed particle generation unit in this chamber system were designed to meet the needs of simulating multiphase atmospheric chemical reactions. The AIR chamber is able to accurately control temperature (2.5–31 ± 0.15 ∘C) and
relative humidity (RH <2 %–>95 % ± 0.75 %) over a relatively broad range. In addition, an RH regulation module inside the chamber was designed to simulate the diurnal variation of ambient atmospheric RH. The aerosol generation unit is able to generate pre-deliquescent seed particles with an organic coating across a
wide range of phase states or morphologies. The organic coating thickness of the aerosols within the chamber can be precisely controlled through
adjusting the condensation temperature, further helping to elucidate the
roles of seed particles in multiphase chemical reactions. The inner walls of the AIR chamber are passivated to reduce the wall loss rates of reactive
gases. Yield experiments of α-pinene ozonolysis with and without
seed particles combined with a box model simulation demonstrate the
high-quality performance of secondary aerosol formation simulation using the AIR chamber.

Published: August 2023

Abstract. There is a temporal correlation between the peak activity of the North
Atlantic Igneous Province (NAIP) and the Paleocene–Eocene Thermal Maximum
(PETM), suggesting that the NAIP may have initiated and/or prolonged this
extreme warming event. However, corroborating a causal relationship is
hampered by a scarcity of expanded sedimentary records that contain both
climatic and volcanic proxies. One locality hosting such a record is the island of Fur in Denmark, where an expanded pre- to post-PETM succession containing
hundreds of NAIP ash layers is exceptionally well preserved. We compiled a
range of environmental proxies, including mercury (Hg) anomalies,
paleotemperature proxies, and lithium (Li) and osmium (Os) isotopes, to
trace NAIP activity, hydrological changes, weathering, and seawater
connectivity across this interval. Volcanic proxies suggest that NAIP
activity was elevated before the PETM and appears to have peaked during the
body of the δ13C excursion but decreased considerably during
the PETM recovery. This suggests that the acme in NAIP activity, dominated
by flood basalt volcanism and thermogenic degassing from contact
metamorphism, was likely confined to just ∼ 200 kyr (ca. 56.0–55.8 Ma). The hundreds of thick (> 1 cm) basaltic ashes in the post-PETM strata
likely represent a change from effusive to explosive activity, rather than
an increase in NAIP activity. Detrital δ7Li values and clay
abundances suggest that volcanic ash production increased the basaltic reactive
surface area, likely enhancing silicate weathering and atmospheric carbon
sequestration in the early Eocene. Signals in lipid biomarkers and Os
isotopes, traditionally used to trace paleotemperature and weathering
changes, are used here to track seaway connectivity. These proxies indicate
that the North Sea was rapidly cut off from the North Atlantic in under 12 kyr during the PETM recovery due to NAIP thermal uplift. Our findings
reinforce the hypothesis that the emplacement of the NAIP had a profound and
complex impact on Paleocene–Eocene climate, both directly through volcanic
and thermogenic degassing and indirectly by driving regional uplift and
changing seaway connectivity.

Published: August 2023

Abstract. Lakes and reservoirs are ubiquitous across global landscapes, functioning as the largest repository of liquid surface freshwater, hotspots of carbon
cycling, and sentinels of climate change. Although typically considered lentic (hydrologically stationary) environments, lakes are an
integral part of global drainage networks. Through perennial and intermittent hydrological connections, lakes often interact with each other, and
these connections actively affect water mass, quality, and energy balances in both lacustrine and fluvial systems. Deciphering how global lakes are
hydrologically interconnected (or the so-called “lake drainage topology”) is not only important for lake change attribution but also increasingly
critical for discharge, sediment, and carbon modeling. Despite the proliferation of river hydrography data, lakes remain poorly represented in
routing models, partially because there has been no global-scale hydrography dataset tailored to lake drainage basins and networks. Here, we
introduce the global Lake drainage Topology and Catchment database (Lake-TopoCat), which reveals detailed lake hydrography information with
careful consideration of possible multifurcation. Lake-TopoCat contains the outlet(s) and catchment(s) of each lake; the interconnecting reaches
among lakes; and a wide suite of attributes depicting lake drainage topology such as upstream and downstream relationship, drainage distance between
lakes, and a priori drainage type and connectivity with river networks. Using the HydroLAKES v1.0 (Messager et al., 2016) global lake mask, Lake-TopoCat identifies
∼ 1.46 million outlets for ∼ 1.43 million lakes larger than 10 ha and delineates 77.5×106 km2 of lake catchments
covering 57 % of the Earth's landmass except Antarctica. The global lakes are interconnected by ∼ 3 million reaches, derived from MERIT Hydro v1.0.1 (Yamazaki et al., 2019), stretching a total distance of ∼10×106 km, of which ∼ 80 % are shorter than 10 km. With such
unprecedented lake hydrography details, Lake-TopoCat contributes towards a globally coupled lake–river routing model. It may also facilitate a
variety of limnological applications such as attributing water quality from lake scale to basin scale, tracing inter-lake fish migration due to changing
climate, monitoring fluvial–lacustrine connectivity, and improving estimates of terrestrial carbon fluxes. Lake-TopoCat is freely accessible at

Gas-Equilibrium Membrane Inlet Mass Spectrometery (GE-MIMS) for water at high pressure
Authors: Brennwald Matthias S. , Rinaldi Antonio P. , Gisiger Jocelyn , Zappone Alba , Kipfer Rolf
Published: August 2023

Abstract. Gas species are widely used as natural or artificial tracers to study fluid dynamics in environmental and geological systems. The recently developed gas-equilibrium membrane-inlet mass spectrometry (GE-MIMS) method is most useful for accurate and autonomous on-site quantification of dissolved gases in aquatic systems. GE-MIMS works by pumping water through a gas equilibrator module containing a gas headspace, which is separated from the water by a gas-permeable membrane. The partial pressures of the gas species in the headspace equilibrate with the gas concentrations in the water according to Henrys Law, and are quantified with a mass spectrometer optimized for low gas consumption (miniRUEDI or similar). However, the fragile membrane structures of the commonly used equilibrator modules break down at water pressures ≳ 3 bar. These modules are therefore not suitable for use in deep geological systems or other environments with high water pressures. To this end, the SysMoG® MD membrane module (Solexperts AG, Switzerland; “SOMM”) was developed to withstand water pressures of up to 100 bar. Compared to the conventionally used GE-MIMS equilibrator modules, the mechanically robust construction of the SOMM module entails slow and potentially incomplete gas/water equilibration. We tested the gas-equilibration efficiency of the SOMM and developed an adapted protocol that allows correct operation of the SOMM for GE-MIMS analysis at high water pressures. This adapted SOMM GE-MIMS technique exhibits a very low gas consumption from the SOMM to maintain the gas/water equilibrium according to Henrys Law and provides the same analytical accuracy and precision as the conventional GE-MIMS technique. The analytical potential of the adapted SOMM GE-MIMS technique was demonstrated in a high-pressure fluid-migration experiment in an underground rock laboratory. The new technique overcomes the pressure limitations of conventional gas equilibrators and thereby opens new opportunities for efficient and autonmous on-site quantification of dissolved gases in high-pressure environments, such as in research and monitoring of underground storage of CO2 and waste deposits, or in the exploration of natural resources.

Published: August 2023

Abstract. Maintaining good surface water quality is crucial to protect ecosystem
health and for safeguarding human water use activities. However, our
quantitative understanding of surface water quality is mostly predicated
upon observations at monitoring stations that are highly limited in space
and fragmented across time. Physical models based upon pollutant
emissions and subsequent routing through the hydrological network provide
opportunities to overcome these shortcomings. To this end, we have developed
the dynamical surface water quality model (DynQual) for simulating water
temperature (Tw) and concentrations of total dissolved solids (TDS),
biological oxygen demand (BOD) and fecal coliform (FC) with a daily time step
and at 5 arcmin (∼ 10 km) spatial resolution. Here, we
describe the main components of this new global surface water quality model
and evaluate model performance against in situ water quality observations.
Furthermore, we describe both the spatial patterns and temporal trends in
TDS, BOD and FC concentrations for the period 1980–2019, and we also attribute
the dominant contributing sectors to surface water pollution. Modelled
output indicates that multi-pollutant hotspots are especially prevalent
across northern India and eastern China but that surface water quality
issues exist across all world regions. Trends towards water quality
deterioration have been most profound in the developing world, particularly
sub-Saharan Africa and South Asia. The model code is available
open source (https://doi.org/10.5281/zenodo.7932317, Jones et al., 2023), and we
provide global datasets of simulated hydrology, Tw, TDS, BOD and FC at 5 arcmin resolution with a monthly time step (https://doi.org/10.5281/zenodo.7139222, Jones et al., 2022b). These data have the potential to inform
assessments in a broad range of fields, including ecological, human health
and water scarcity studies.
Automatic Labels in Leaflet
Authors: Gede Mátyás
Published: August 2023

Abstract. Automatic labelling is a lacking feature in the popular client-side web mapping library, Leaflet. Although there exist various workarounds and substitutes, most of these do not fulfil the basic cartographic rules, e.g. avoiding text overlaps.This paper discusses the various workarounds addressing this problem, and introduces the author’s solution, which extends Leaflet’s GeoJSON class with automatic labelling functionality. The new class displays labels for point, line or polygon features. Labels can be placed either on right or left side of points or automatically for better fitting. Markers for points are only displayed if their labels can be drawn without overlaps. Label text is specified either by property field name or a user-specified function. It is also possible to specify priority order of features (higher priority labels are drawn first) and to customize label styles.
Exploring the potential of an Augmented Reality sandbox for geovisualization
Authors: Bärthele Rebekka , Sauer Stefan , Wilkening Jan
Published: August 2023

Abstract. Geovisualization provides theories, methods, and tools for visualizing processes on the earth’s surface. One of the key challenges of the field is to find interesting and engaging ways to display geographical data. In this paper, we focus on the Augmented Reality (AR) Sandbox. An AR Sandbox combines a box filled with sand with a 3D camera and a projector to explore the topography of the sand terrain in real time and allow water flow simulations. This direct interaction between user and topography makes the AR sandbox a fascinating, explorative tool in the field of geovisualization.In this paper, we give an overview about how an AR Sandbox is built, what components are required, and how configuration, calibration or adding additional features work. We also discuss ways to improve the usability of the AR Sandbox or change its appearance to make it more suitable for specific use cases in geovisualization. Of particular importance is the DEM tool, which allows real-life data to be remodeled in the AR Sandbox to explore the terrain, create rainfall simulations, or export the current terrain as a DEM. Further advantages of using an AR sandbox for geovisualization are the hands-on methodology and gamification aspects, which motivate people to interact with topography and improve learning effects in the geosciences.
Inverse Distance Weighting as an alternative interpolation method to create radiometric maps of natural radionuclide concentrations using QGIS
Authors: le Roux Rikus , Henrico Susan , Bezuidenhout Jacques , Henrico Ivan
Published: August 2023

Abstract. A previous study by the authors illustrated the distribution of naturally occurring radionuclides, i.e., potassium (K40), thorium (Th232), and uranium (U238), in the sediment of the Berg River estuary. The study also described the Delta Underwater Gamma detection System (DUGS) and its usage to measure the concentrations of these natural radionuclides. It also proposed a novel radiometric mapping technique with QGIS and, more importantly, highlighted the geospatial process through Kernel Density Estimation (KDE) to create radiometric maps. The present study used the same data and a similar design but proposed the use of the Inverse Distance Weighted (IDW) interpolation method in QGIS to display natural radionuclide concentrations. The radiometric maps created in the previous study using the KDE technique created smooth and visually attractive maps. However, the IDW method is an exact interpolation method that predicts a value at a sampling location that is identical to the observed value. This is a requirement for the analysis of natural radionuclide concentrations in sediments. However, the effectiveness of the interpolation methods was evaluated using SPSS statistics software. First, probability-probability (P-P) plots were produced for each interpolation method. Secondly, descriptive regression statistics, including 'goodness-of-fit', Analysis-of-Variance (ANOVA), coefficients, and residuals were evaluated for both the IDW and KDE interpolation methods. This was done to assess which method was more effective for calculating the radionuclide concentrations (actual vs predicted values) in the Berg River area. The results showed that both methods experienced problems to predict unknown values. However, IDW consistently performed better than KDE across most of the interpolation tests. Natural radionuclides are useful predictors to track sedimentation and the results of this paper can serve as a benchmark for future work in tidal and non-tidal coastal environments.
Analysis of Cartographic Symbols as Visual Support in Interactive VR Geovisualizations
Authors: Olberding Helge , Vetter Mark
Published: August 2023

Abstract. Game engines and head-mounted displays (HMD) can create interactive virtual reality (VR) cartographies. Many VR geovisualizations try to depict places as close to reality as possible. The scaling is 1:1 for most VR geovisualizations. If VR geovisualizations are too close to reality or complex, users can navigate through them better, but the amount of detail makes it more challenging to target information. With the help of cartographic elements, a more targeted focus can again be acquired. The focus and style of VR cartography depend on the topic. The topics selected were "Floods and heavy rainfall events", "Noise propagation analysis", and "Lighting simulation". These are three topic examples in which 3D city models are used. CityGML models and fictitious 3D objects were used. Different rendering techniques and point signatures were implemented for each of the themes. All three topics were implemented in an application as a serious game. With the help of an interactive interface and motion controllers, users can change and navigate all three themes. Solution-oriented objects can be placed on all three topics as an additional interactive element. These options allow users to learn targeted information through various presentation options and implement solutions.
Primary Health Care Accessibility in Zomba, Malawi: A Spatial Modelling Approach
Authors: Phiri Yamikani , Munthali Kondwani Godwin
Published: August 2023

Abstract. Access to primary health care (PHC), as the first point of care, is an essential factor in influencing the health status of a society. In Malawi, an individual is considered to have access to health care if they are within an 8 km radius to a health facility. Based on this, the Health Sector Strategic Plan (HSSP) II, 2017–2022 puts access to PHC in Malawi at 90 %. However, a Demographic Health Survey (DHS) reports that 56 % of women find distance as a major barrier. As such the aim of the study was to model spatial access to health of households in the district. The study used the 2 Step Floating Catchment Area (2FCSA) with Gaussian decay function method to model health care access and the greedy algorithm to find optimal locations for new facilities. The study found that 62% households have the potential of walking 60 minutes to the facility, a figure 28 % lower than the one reported by HSSP. With 2SFCA scores ranging from 0 to 0.19, the results show that 98 % and 57 % of the households scored between 0.031 to 0.046 for urban and rural areas respectively. These scores imply that urban households have better spatial accessibility than rural households. The results provide a spatially objective PHC accessibility data to inform policy direction.

Published: August 2023

Abstract. The Sustainable Development Goals aim to "leave no one behind," including visually impaired individuals who should have equal access to information. However, the production of tactile maps for the visually impaired has been inhibited by factors such as a lack of data and technology, cartographical challenges, and high production costs. To address this issue, two research projects developed prototype tactile maps for visually impaired users and evaluated their usability through a focus group discussion and hands-on experience. In the first project, the maps were appreciated for their continuous style, thematic versatility, and proportional information density. Suggestions for improvement included the addition of a clear map title, an overview map, a mandatory legend, and distinguishable icons. Tactile maps were seen as supplementary to mobile navigation by providing a geographical overview, information about locations of interest, creating and correcting cognitive pictures of the living environment, and sharpening geographical and common knowledge. The second project focused on refining the results in multiple iterations, and for this purpose a multidisciplinary consortium was formed that, in collaboration with a test panel of visually impaired users, contributed to the aim of making tactile topography on-demand, fit-for-purpose and globally available.

Abstract. In this study the authors investigated the possibilities to use open data and open software complemented with machine learning to enhance the content of municipal databases. In the study area in Székesfehérvár, a GIS system is used with approximately with 30 modules, although many are still missing. The authors prepared examine the easiest and most affordable methods to extract data to use in two future modules: Parking and Traffic Engineering module. In parking model along field survey, they used QGIS and OpenStreetMap, in the other module they used Google StreetView for defining the places of traffic signs and used machine learning to define the signposts. They found that the accuracy of creating the parking module is based on the completeness of the database and the field measurement method, in case of the Traffic Engineering method the up-to-dateness and completeness of the original data source (Google Street View) and the number of teaching samples influence the results.
Tasks and challenges of the Head Office of Geodesy and Cartography in the area of developing topographic maps in 1:25,000 scale

Published: August 2023

Abstract. In accordance with the legal regulations in force in Poland in the field of cartography, i.e. the Geodetic and Cartographic Law, one of the tasks of the Chief National Surveyor is to create and provide access to topographic, general geographic, thematic and special maps. Moreover, the topographic maps are developed in close cooperation with the Minister of National Defense. The basis for the development of topographic maps is, in particular, the Topographic Objects Database BDOT10k with the topographic objects’ level of details corresponding to 1:10,000 scale, the National Register of Geographic Names and the Digital Terrain Model.Considering the above, in 2022, the Head Office of Geodesy and Cartography, as part of its own work, launched a pilot project aimed at developing tools to automatically generate topographic maps in 1:10,000 and 1:25,000 scale. At a current stage, as part of the II iteration, the maps do not yet constitute full-fledged topographic maps, but we are striving for such a goal. The tools are constantly developed and corrections are made to eliminate errors that still occur. The maps in 1:10,000 and 1:25,000 scales, developed so far under this project in a fully automatic manner, are available free of charge to all interested users on the www.geoportal.gov.pl website.In the article, the results of the developed tools and generated topographic maps 1:25,000 will be presented, as well as the problems faced both in the context of the methodology and the limitations resulting from the software used.
Assimilation of surface pressure observations from personal weather stations in AROME-France
Authors: Demortier Alan , Mandement Marc , Pourret Vivien , Caumont Olivier
Published: August 2023

Abstract. Spatially dense surface pressure observations from personal weather stations (PWSs) have proved their ability to describe physical meteorological patterns, such as convective events, which are not visible with the only use of standard weather stations (SWSs). In this study, the benefit of assimilating PWS observations with the 3DVar and the 3DEnVar data assimilation schemes of the AROME-France model is evaluated over a 1-month period and during a heavy precipitation event in the south of France. Observations of surface pressure from PWSs are bias-corrected, quality-controlled, and thinned with a spacing equal to the horizontal dimension of an AROME-France grid cell. Over France, almost half of the 55 187 available PWS observations are assimilated, which is 129 times more than the number of assimilated SWSs observations. Despite the small advantages found from their assimilation with the 3DVar assimilation scheme, the 3DEnVar assimilation scheme shows systematic improvement and reduces by −10.3 % the root-mean-square departure in surface pressure between 1 h model forecasts and SWS observations over France. Significant improvement is observed up to 9 h of forecast in mean sea level pressure. Finally, when PWS observations are assimilated with the 3DEnVar assimilation scheme, a surface pressure anomaly generated by a mesoscale convective system – observed by PWSs and not visible without them – is successfully assimilated. In that case, the forecasts of location and temporal evolution of the mesoscale convective system as well as rainfall are closer to the observations when PWS observations are assimilated.

Abstract. The Aneto glacier, although it may be considered a very small
glacier (<0.5 km2), is the largest glacier in the Pyrenees.
Its surface and thickness loss have been continuous in recent decades, and
there have been signs of accelerated melting in recent years. In this study,
thickness and surface losses of the Aneto glacier from 1981 to 2022 are
investigated using historical aerial imagery, airborne lidar point clouds
and unoccupied aerial vehicle (UAV) imagery. A ground-penetrating radar (GPR) survey conducted in 2020, combined with data from
photogrammetric analyses, allowed us to reconstruct the current ice
thickness and also the existing ice distribution in 1981 and 2011. Over the
last 41 years, the total glacierised area has decreased by 64.7 %, and the
ice thickness has decreased, on average, by 30.5 m. The mean remaining ice
thickness in autumn 2022 was 11.9 m, as against the mean thickness of 32.9, 19.2 and 15.0 m reconstructed for 1981 and 2011 and observed in 2020,
respectively. The results demonstrate the critical situation of the glacier,
with an imminent segmentation into two smaller ice bodies and no evidence of
an accumulation zone. We also found that the occurrence of an extremely hot
and dry year, as observed in the 2021–2022 season, leads to a drastic
degradation of the glacier, posing a high risk to the persistence of the
Aneto glacier, a situation that could extend to the rest of the Pyrenean
glaciers in a relatively short time.
Potential Benefits of Mindfulness-Based Strength Practice for Individuals With Disabilities in Vocational Rehabilitation Settings

Positive psychology has brought us two key tools to support the well-being of individuals: character strengths and mindfulness. Character strengths, or the positive characteristics that make up who a person is, can be utilized to build awareness on identity and ability. Character strengths interventions have been researched for several decades, with newer utilizations in rehabilitation settings. Similarly, mindfulness, while originating centuries ago, has found modern uses in vocational settings. Mindfulness, defined as the ability to maintain attention in an intentional way, has been scientifically shown to improve well-being. These two interventions have recently been combined within Mindfulness-Based Strength Practice (MBSP; Niemiec, 2014). This intervention focuses on character strengths and mindfulness in a combined format and has shown preliminary evidence for benefit in a variety of settings. This paper explores MBSP and proposes its potential benefits in vocational rehabilitation settings, along with additional research implications and considerations for practice.

To translate and culturally adapt the Perceived Physical Literacy Instrument (PPLI) questionnaire, as well as to evaluate the factor structure. A single-measure cross-sectional study was conducted. For the first phase of the study, a translation and cultural adaptation of the PPLI questionnaire was carried out, as well as an interview, with the aim of assessing the understanding of the instrument. In the second part of the study, exploratory (EFA) and confirmatory (CFA) factorial analyses were conducted. A total of 213 Spanish adults with a mean age of 27.40 (10.58) participated. EFA was performed because of the good results offered by the sampling adequacy indices (Bartlett test = 1081.848; df = 153; p < 0.001; and KMO test = 0.825). The factor solution comprised three correlated factors:1) physical competence, 2) motivation and confidence, and 3) knowledge and understanding. After the EFA, items 7, 9, 10, 11, 12, 13, 14, 15 and 17 were excluded. Therefore, through CFA, a factor structure of 9 items grouped into three dimensions was extracted. The PPLI-Sp version for adults, obtained from the back-translation process as well as after individual interviews, proved to be valid and reliable after the EFA and CFA analyses, obtaining an instrument of nine items, divided into three dimensions. This instrument can be used to determine the perception of physical literacy among different Spanish adult populations.

La espiritualidad a través de la música en la poesía de Francisco Luis Bernárdez
Authors: Sarfson Susana
Published: August 2023

La expresión lírica del poeta argentino Francisco Luis Bernárdez (1900-1978) se desarrolla a partir de una serie de influencias que van desde los escritores modernistas y ultraístas a las de los poetas áureos. Sin embargo, a medida que consolida su voz personal, tres cuestiones emergen como constantes en su obra: la música, la búsqueda de lo sagrado y la angustia. En la poiesis del autor, la música se manifiesta como vehículo del espíritu. Este trabajo expone y ejemplifica estas tres ramas de un mismo punto de interés del poeta: la espiritualidad como destino del ser humano.

A comparative study on incorporation of green manure crop (Sesbania aculeata) with a newly developed tractor operated biomass incorporator (BI) was conducted in contrast to prevailing technologies. Average depth of soil cut with BI (174.7 mm) was significantly higher than rotavator (71.3 mm), disc harrow (114 mm) and disc harrow plus cultivator (121 mm) at crop growth stage I (36 DAS) and stage II (50 DAS). Size of cut with BI (202 mm and 326.5 mm) was significantly lower than disc harrow, disc harrow pluscultivator and mould board plough at crop growth stage I and II. Field capacity of BI and conventional mould board plough was significantly lower than rotavator and disc harrow because of smaller width of coverage of two-bottom implements. Fuel consumption was significantly higher for rotavator at both stages of crop growth. Pulverization index was lowest with rotavator (6.70 mm and 6.98 mm), followed by BI, disc harrow plus cultivator, disc harrow and mould board plough at both crop stages. Bulk density index was significantly high for BI, followed by rotavator, mould board plough, disc harrow plus cultivator and disc harrow at both crop stages. Mixing index with BI (97.1 %) was significantly higher than all other implements. Biomass incorporator resulted in analogous mixing index at both crop stages. For all other implements, decrease in mixing index was recorded.

In the present study, biometric properties of chilli (Pusa Jwala) and tomato (Abhilash) plug seedlings of 30-, 45- and 60-day old relevant to design of vegetable transplanter were investigated. The parameters determined were weight, stem diameter, height, critical canopy diameter, drop shatter height, compressive strength and coefficient of static friction of the plug seedlings. The average weight of chilli seedlings was 13.1, 15.2 and 15.9 g for 30-, 45- and 60-day old, respectively; whereas, that for tomato seedling was 13.4, 14.1 and 14.5 g for 30-, 45- and 60-day old, respectively. The optimum drop shatter height with minimum shattering of plug media for both seedlings was 400 mm. The critical canopy diameter for chilli and tomato seedling was 68.2 mm and 70.4 mm, respectively. The mean coefficient of static friction for canvas belt, mild steel, aluminium and galvanized iron varied from 0.63 to 0.89. The compressive strength of stem of seedlings ranged from 1.2 kgf to 1.6 kgf. These properties of vegetable seedlings are critical in designing and selection of different components of vegetable transplanter.
