Quantifying uncertainty in probabilistic volcanic ash hazard forecasts, with an application to weather pattern based wind field sampling
Authors: Phillips Jeremy , Williams Shannon , Lee Anthony , Jenkins Susanna 
Published: October 2023

AbstractProbabilistic forecasting of volcanic ash dispersion involves simulating an ensemble of realistic event scenarios to estimate the probability of a particular hazard threshold being exceeded. Although the number of samples that make up the ensemble, how they are chosen, and the desired threshold all set the uncertainty of (or confidence in) the estimated exceedance probability, current practice does not quantify and communicate the uncertainty in ensemble predictions. In this study, we use standard statistical methods to estimate the variance in probabilistic ensembles and use this measure of uncertainty to assess different sampling strategies for the wind field, using the example of volcanic ash transport from a representative explosive eruption in Iceland. For stochastic (random) sampling of the wind field, we show how the variance is reduced with increasing ensemble size and how the variance depends on the desired hazard threshold and the proximity of a target site to the volcanic source. We demonstrate how estimated variances can be used to compare different ensemble designs, by comparing stochastic forecasts with forecasts obtained from a stratified sampling approach using a set of 29 Northern European weather regimes, known as Grosswetterlagen (GWL). Sampling wind fields from within the GWL regimes reduces the number of samples needed to achieve the same variance as compared to conventional stochastic sampling. Our results show that uncertainty in volcanic ash dispersion forecasts can be straightforwardly calculated and communicated, and highlight the need for the volcanic ash forecasting community and operational end-users to jointly choose acceptable levels of variance for ash forecasts in the future.

Abstract
Key message
The physiological responses expressed by variation in carbon and oxygen stable isotopes and iWUE in five provenances of maritime pine grown in four common gardens were primarily determined by genotype differences in phenotypic plasticity and secondarily by genotype.

Abstract
Given the impacts of climate change on forest resources and considering the slowness of evolutionary processes in trees, a need arises to understand the interplay between tree species adaptation to climate, genetic variation, and their impact on tree growth and productivity. Broadening knowledge of the capacity of tree populations to respond to climate-related disturbances is a prerequisite for the development of resilience strategies, including assisted migration and climate-smart forestry. This study tests the physiological ability of different maritime pine provenances, comparing Mediterranean (Corsica, Sardinia, and Tuscany) and Atlantic (Portugal) provenances, to adapt to progressively drier conditions that have occurred in the last thirty years. Four provenance trials with randomized blocks of the five maritime pine provenances were used as test sites in Sardinia (Italy). Wood cores were collected from the 40-year-old plants. Cores were split into five-year segments to determine provenance-related variations in carbon and oxygen stable isotopes and provide information on long-term patterns in intrinsic water use efficiency (iWUE). The provenance × site interaction was the most important source of variation, meaning that the genotypes responded differently to the planting sites. Considering the main effects, both genotype and environmental conditions at the planting sites influenced stable isotope composition in tree rings. This suggests that iWUE was determined by phenotypic plasticity that differed among genotypes. In contrast, provenance responses were stable with time, and the provenance × site interaction was stable across time periods. These findings suggest that provenance selection to improve iWUE in maritime pine may need to consider site conditions but point more to soil conditions than to climate. In any case, they limit our ability to recommend maritime pine provenances based on iWUE until the missing site factors can be identified.
A priori bounds for GIETs, affine shadows and rigidity of foliations in genus two
Authors: Ghazouani Selim , Ulcigrai Corinna 
Published: October 2023

AbstractWe prove a rigidity result for foliations on surfaces of genus two, which can be seen as a generalization to higher genus of Herman’s theorem on circle diffeomorphisms and, correspondingly, flows on the torus. We prove in particular that, if a smooth, orientable foliation with non-degenerate (Morse) singularities on a closed surface of genus two is minimal, then, under a full measure condition for the rotation number, it is differentiably conjugate to a linear foliation.The corresponding result at the level of Poincaré sections is that, for a full measure set of (standard) interval exchange transformations (IETs for short) with $d=4$

-conjugate to it. This in particular settles a conjecture by Marmi, Moussa and Yoccoz in genus two. Our results also show that this conjecture on the rigidity of GIETs can be reduced to the study of affine IETs, or more precisely of Birkhoff sums of piecewise constant observables over standard IETs, in genus $g \geq 3$

we prove a dynamical dichotomy on the behaviour of the orbits under renormalization, by proving that either an orbit is recurrent to certain bounded sets in the space of GIETs, or it diverges and it is approximated (up to lower order terms) by the orbit of an affine IET (a case that we refer to as affine shadowing). This result can in particular be used, in conjunction with previous work by Marmi-Moussa and Yoccoz on the existence of wandering intervals for affine IETs, to prove, a priori bounds in genus two and is therefore at the base of the rigidity result.
Earthquake and structural engineering science for civil protection
Authors: Dolce Mauro 
Published: October 2023

AbstractA close relationship between civil protection organizations and scientific community is widely recognized today at international and European level as being of paramount importance for the effectiveness of research products in their application for disaster risk management. In this perspective, European research projects on risks are more and more focused on application oriented outcomes, requiring the involvement of civil protection organizations, and creating a well-structured knowledge network within a European civil protection framework. For about forty years, the Italian civil protection has been relying upon the contribution of the scientific community to find the best solutions based on the most advanced and consolidated knowledge, for activities that concern the management of the entire disaster risk cycle. The interactions between civil protection and scientific community in Italy are mainly based on the so-called Competence Centers, i.e. the scientific operational partners of the Civil Protection Department (DPC), and on the Major Risks Commission, i.e. the technical-scientific advisory body of DPC. They both work with an interdisciplinary, multisectoral and, when necessary, multi-hazard risk approach. This paper aims to describe how Competence Centers presently operate, in a way that has evolved over the years. The focus will be on scientific activities and products related to the earthquake and structural engineering science, emphasizing the way of operating and collaborating of Competence Centers, consistently with the principles of the Italian Civil Protection Code.
Ultrasound assistance synthesis of optimized ion imprinted polymer for efficient and selective removal of cobalt ions from waste streams
Authors: Hamed Mahmoud Goneam , Borai Emad Hassan 
Published: October 2023

AbstractSelective recognition of metal ions is a real challenge for a large range of applications especially in sorption purposes. The use of ultrasound in the synthesizing and modifying of sodium alginate-based material is investigated, for enhancing the dispersion, degassing, crosslinking processes and enhance the homogeneity of ion imprinted polymer properties. Cobalt imprinted polymer was prepared using an inexpensive and simple ultrasonic-mediated polymerization process that incorporated dual functional monomers, acrylic acid, and 2-Acrylamido-2-methylpropane sulfonic acid to feature a multifunctional of carboxylic and sulfonic groups. SEM, TGA, DTA, and EDX were used to analyze the surface morphology. FT-IR study confirmed that the complexation of the Co-IIP was successfully takes place. The ability of the adsorption of ion imprinted was optimized at pH 5. The increase of the temperature from 27 to 52 °C caused the increase in the adsorption capacity. Batch tests have been performed to evaluate the selectivity mechanism, and found that the prepared polymer exhibit excellent selectivity for Cobalt, more than nickel, and strontium at 300°K (single component) were 71, 20, and 12 mg.g−1 respectively. Pseudo-second-order kinetics and the Langmuir isotherm gave the most satisfactory explanation for the adsorption process. The prepared polymer can be reused 5 times with a very low loss in adsorption capacity. The prepared ion imprinted polymer is efficiently utilized in controlling Co2+ sorption/desorption processes, enabling its successful recovery from complex sample matrices for various applications especially that required separation processes.

Published: October 2023

Abstract
Aims
The objective of this study was to identify the most suitable substrate for Cannabis sativa L. cultivation based on its effects on water relations and Cannabidiol (CBD) production.

Methods
Biomass, physiological parameters, minerals, changes in the expression levels of plasma membrane intrinsic Proteins (PIP) and CBD concentration was measured in C. sativa (var. Tiborszallasi) plants cultivated on 5 substrates with different physical–chemical characteristics.

Results
The substrates available water (AW) was the main factor affecting growth and production. The efficiency of the water use was governed fundamentally by transpiration. Experimental substrates(S) 1 and 3 (S1 and S3) were those in which the plants grew optimally and allows plants to invest energy in secondary metabolites production acquiring high levels of CBD. The plants grown in S2 and S5, composed by coconut fiber and perlite, showed the lowest growth in agreement with low transpiration rates which reduce the water uptake. S5 substrate, with some available water (AW) still present, is forcing plants to invest energy in improving water and nutrient transport, as observed by the high levels of nutrients in planta and PIPs expression levels. S4 plants presented the highest inflorescence production and CBD content, which can be attributed to plant stress due to the low levels of AW and high pH and electrical conductivity (EC).

Conclusion
The absorption of water and minerals by plants has been affected by PIP-mediated water transport, playing key roles for the optimal utilization of the water present in the substrates, with specific isoforms involved in these responses.
Assesment of Hypoderma infestation in a wild population of Cervus elaphus from mountains Atlantic ecosystems in southwestern Europe (Spain)

Published: October 2023

AbstractHypodermosis in Cervus elaphus was studied in the Riaño Regional Hunting Reserve, Province of León, north-western Spain. One hundred and ten red deer were examined for the presence of warble fly larvae. They were analyzed by PCR analysis of the COI region of mt-DNA and identified as Hypoderma actaeon. The prevalence of larvae was 42.7% with a mean intensity of 12.5 ± 18 (range 1–80) warbles/deer infested. The distribution of larvae in the infested animals showed an aggregated/overdispersed pattern (aggregation index = 25.84), where the larvae are not randomly or uniformly distributed, but strongly aggregated among their hosts. Larvae were found in all three states. First and second-instars were observed mainly in the autumn until the end of winter (November-March) and third-instars in late winter until mid-spring (March–May). The adult animals and the males had a higher prevalence than the young and the females, finding statistically significant differences only according to the sex of the animals. Seasonal variations were observed in the prevalence with the highest number of infested animals in winter and autumn, but not in terms of the mean intensity of parasites. Additionally, we assessed the presence of anti-Hypoderma antibodies in serum by means of indirect ELISA tests, using a crude larval extract (CLE) and a purified fraction the hypodermin C (HyC) obtained from first instars of Spanish isolates of Hypoderma lineatum (cattle). These findings confirm that H. actaeon is widely distributed in northern Spain, and provide new information about its chronobiology in mountainous Atlantic ecosystems from southwestern Europe.

Published: October 2023

AbstractThis study focused on determining the effect of the inoculum to substrate ratio (ISR) on biogas production efficiency from the anaerobic co-digestion of two substrates: synthetic food waste and common reeds (Phragmites australis) that were ground and pre-treated using sodium hydroxide at a concentration of 2% to increase access to their cellulose. It also studied the role of different mixing ratios of the two substrates in improving the stability of the digestion process and increasing biogas production. A series of batch tests were carried out under mesophilic conditions using three ratios of ISR: 1:4, 1:2, and 1:1, and five substrate mixing ratios (synthetic food waste: pre-treated P. australis): 25:75, 50:50, 75:25, 100:0, and 0:100. The results showed low biogas production at the ISR 1:4 (21.58±0.00–44.46±0.01 mL/g volatile solid (VS) added), and the reactors suffered from acidification at the different substrates mixing ratios, while the biogas production increased at an ISR of 1:2, where the reactors with the substrate mixing ratio of 25:75 presented the highest biogas production (82.17±0.62 mL/g VS added), and the digestion process was stable. However, the reactors with substrate mixing ratios of 50:50, 75:25, and 100:0 suffered from acidification effects at this ISR. In contrast, at ISR of 1:1, the reactors did not expose to acidification inhibition at all the substrates mixing ratios, and the highest biogas production was found at synthetic food waste: pre-treated P. australis mixing ratios of 75:25 and 100:0 (76.15±1.85 and 82.47±1.85 mL/g VS added, respectively).

AbstractNeurodevelopmental disorders are increasing globally, and metal exposure may play a significant role as an environmental factor. This cross-sectional study aimed to identify metal mixture patterns and assess their impact on children’s neurodevelopment. Data from 962 children (aged 4–5 years) participating in the Spanish INMA cohort study were analysed. Urinary metal concentrations (cobalt (Co), copper (Cu), molybdenum (Mo), selenium (Se), lead (Pb), zinc (Zn), and arsenic speciation) were used as exposure biomarkers. Principal component analysis (PCA) revealed four latent exposure variables representing uncorrelated metal mixture patterns. Linear regression analyses examined the associations between these variables and children’s neuropsychological functions assessed through the McCarthy Scales of Children’s Abilities. The first latent exposure variable (Cu, Se, Pb, Zn) and the second (inorganic arsenic, monomethylarsonic acid) showed negative associations with verbal executive function (ß =  − 1.88, 95% confidence interval (CI) =  − 3.17 to − 0.59) and gross motor function (ß =  − 1.41, 95% CI =  − 2.36 to − 0.46), respectively. Conversely, the third variable (Mo, Co) and the fourth (arsenobetaine) exhibited positive associations with visual and verbal span functions (ß = 1.14, 95% CI = 0.16 to 2.12) and fine motor function (ß = 1.01, 95% CI = 0.11 to 1.92), respectively. This study suggests that even relatively low levels of metal latent exposures, notably inorganic arsenic and a mixture of metals including Pb, adversely affect children’s neuropsychological development function scores, while exposure to arsenobetaine and a mixture of Co and Mo has a positive impact.
In the land of tin men? Warrior stelae, mobility, and interaction in western Iberia during the Late Prehistory
Authors: Rodríguez-Corral Javier , Rodríguez-Rellán Carlos 
Published: October 2023

AbstractThe warrior stelae, also called southwestern stelae or western stelae, emerge as one of the most characteristic manifestations of the Bronze Age in Iberia. Since the earliest findings more than a century ago, these monoliths have received great attention from scholars, becoming the subject of an intense debate, without a consensus having been reached on their meaning and sense. A slow but steady trickle of new findings, as well as the implementation of new approaches to their study, has only enriched these discussions in recent years. One of the most successful lines has been the spatial analysis focused on the relationship of these monuments with routes, transit areas, and resources of great value. It is within this line that this article explores the potential relationship that the stelae may have had with a critical mineral resource: the tin ores distributed in western Iberia, which is the highest concentration of this mineral in Europe. To do this, a detailed spatial analysis has been conducted in order to explore if the uneven density of these monuments across western Iberia may be linked with the presence of tin ores or, alternatively, with the control of the routes that allowed the circulation of this mineral by land.
Becoming an English language teacher over lines of desire: Stories of lived experiences
Authors: Nigar Nashid , Kostogriz Alex , Gurney Laura 
Published: October 2023

AbstractBeyond the notion of decision-making of career choice just being rational, this article proposes the primacy of ‘affect’ in the decision to become teachers over time. The article explores the becoming of immigrant English language teachers as an identity formation process, focusing on the lived experiences of 16 English language teachers since early childhood, mostly prior to their migration to Australia. Findings of the hermeneutic phenomenological narrative analysis of the teachers’ reflective accounts revealed two lines of becoming and their intersections—the line of becoming an English language learner and the line of becoming an English language teacher through decision-making for career choice. The histories of their initial professional decision to ‘become’ English teachers demonstrate the interplay of socially produced desires and personal investment in professional learning and capabilities since early childhood. Through unravelling the assemblages within which their desires to become teachers were fomented and strengthened through embodied lived experiences over a long period of time, we argue that the concept of English teachers’ ‘desired becoming’ informed their initial and long-term decision about career choice. This notion provides a window into the teachers’ decision-making of career choice in terms of the formation of their professional identities as an interplay of the affective and the rational. Embracing and appreciating the combined role of the affective and the rational in teachers’ becoming is important to consider in future research in this area as well as for teacher recruitment and retention, hence potentially addressing critical teacher shortages.
From disenfranchisement to hope through youth-adult participatory action research
Authors: Howell Angelique 
Published: October 2023

AbstractThis paper proposes dovetailing the concept of youth-adult partnership with youth participatory action research to generate a methodology of youth-adult participatory action research. Within contemporary education, deficit-oriented discourses of hopelessness and demoralisation among ‘at risk’ young people and their teachers, particularly those in marginalised and/or high poverty communities, pervade the literature. However, scholarship suggests that negative emotions do not tend to stem from a sense of hopelessness but one of uncertainty, which is typically caused by a lack of accurate information and thus provides a starting point for investigations through integrating reason and emotion. Embedded in Fraser’s conceptualisation of justice as parity of participation, coupled with Freire’s notion of intergenerational dialogue and a critical-democratic conceptualisation of engagement, youth-adult participatory action research seeks to generate communities of praxis in which students, teachers and researchers form explicit tripartite partnerships as co-investigators and co-learners. As they jointly explore their shared concerns, the members of the community mobilise their collective power and agency to co-design context-specific solutions and in so doing, transform the negative emotion and disenfranchisement stemming from uncertainty into a critical hope for more optimistic futures than those alluded to by the ‘at risk’ and ‘disengaged’ policy tags.
