In addition to a balanced production level, the timing of grape harvest is a crucial factor to be considered for the winemaking process of sparkling wines. A sufficient accumulation of sugars and an optimal level of acidity in grapes throughout ripening is necessary not only to achieve the desired alcohol levels in the wine but also to guarantee the biosynthesis of the aromatic precursors. To target optimal grape ripeness and maximise the positive sensory attributes of the wine produced, the work presented herein deals with a study on whether an extended harvest date might have a greater positive organoleptic impact and lead to an increase in important odour–impact compounds. In the resulting Ribolla Gialla monovarietal sparkling wines, a one-week delay after reaching technological maturity of the grapes expressed an improvement in the aromatic profile in the obtained samples by altering the profile and abundance of grape-derived compounds and fermentative esters. This was consequently reflected in the sensory evaluation, as the wines achieved higher scores for ‘floral’, ‘citrus fruit’, and ‘yeast’ sensory descriptors when the grapes were harvested a week after the minimum compromise between total acidity concentration and total soluble solids. Moreover, an extension of the harvest date is not necessarily correlated with the formation of untypical ageing off-flavour substances that could be detrimental to the quality of sparkling wines. Conversely, the lipid content proved to be more dependent on the climatic factors of the individual vintage compared to subsequent harvest time. By merging a multi-targeted approach of exploring wine metabolites and sensory characteristics, it is thus possible to predict an optimal harvest date for obtaining high-quality Ribolla Gialla sparkling wines.
TEMPORAL COREFERENCE IN ENGLISH

Published: May 2024

The article using the material of the English language focuses on studying the issues of temporal coreference. The purpose of the study is to identify the possibilities of implementing temporal coreference using Progressive forms in the English language. In verbal representing temporal reference in English, the referential moment can be expressed by Past Simple, implying a limited interval. These Tense forms may be antecedents for others. The remaining Tenses are anaphoric to it. In case of non-verbal representation of temporal reference, the adverbial modifier of pointed temporal semantics can express the referential moment. Coreference is possible in case of: 1) two non-verbally expressed time intervals, referring to one time interval: the first specifies a larger period, including the second; 2) two verbally expressed intervals; 3) one verbally expressed interval and a second, non-verbally represented. Temporal coreference is represented where a non-verbally expressed referential moment is anaphoric with a time interval verbally implied by predicates in the following Tenses: Past Progressive, Past Simple, Present Progressive, Future Simple. Present Progressive is characterized by coreference with the moment of speech or the present actual moment. Two predicates in Past Progressive and Past Simple can be coreferent to the referential moment represented by the predicate in the Past Simple. Two predicates in Present and Past Progressive can be coreferent provided they are coreferent to the moment of speech or to another moment.
Epitopological Learning and Cannistraci-Hebb Network Shape Intelligence Brain-Inspired Theory for Ultra-Sparse Advantage in Deep Learning

Published: May 2024

Sparse training (ST) aims to ameliorate deep learning by replacing fully connected artificial neural networks (ANNs) with sparse or ultra-sparse ones, such as brain networks are, therefore it might benefit to borrow brain-inspired learning paradigms from complex network intelligence theory. Here, we launch the ultra-sparse advantage challenge, whose goal is to offer evidence on the extent to which ultra-sparse (around 1% connection retained) topologies can achieve any leaning advantage against fully connected. Epitopological learning is a field of network science and complex network intelligence that studies how to implement learning on complex networks by changing the shape of their connectivity structure (epitopological plasticity). One way to implement Epitopological (epi- means new) Learning is via link prediction: predicting the likelihood of non-observed links to appear in the network. Cannistraci-Hebb learning theory inspired the CH3-L3 network automata rule for link prediction which is effective for general-purpose link prediction. Here, starting from CH3-L3 we propose Epitopological Sparse Meta-deep Learning (ESML) to apply Epitopological Learning to sparse training. In empirical experiments, we find that ESML learns ANNs with ultra-sparse hyperbolic (epi-)topology in which emerges a community layer organization that is meta-deep (meaning that each layer also has an internal depth due to power-law node hierarchy). Furthermore, we discover that ESML can in many cases automatically sparse the neurons during training (arriving even to 30% neurons left in hidden layers), this process of node dynamic removal is called percolation. Starting from this network science evidence, we design Cannistraci-Hebb training (CHT), a 4-step training methodology that puts ESML at its heart. We conduct experiments on 7 datasets and 5 network structures comparing CHT to dynamic sparse training SOTA algorithms and the fully connected counterparts. The results indicate that, with a mere 1% of links retained during training, CHT surpasses fully connected networks on VGG16, GoogLeNet, ResNet50, and ResNet152. This key finding is an evidence for ultra-sparse advantage and signs a milestone in deep learning. CHT acts akin to a gradient-free oracle that adopts CH3-L3-based epitopological learning to guide the placement of new links in the ultra-sparse network topology to facilitate sparse-weight gradient learning, and this in turn reduces the convergence time of ultra-sparse training. Finally, CHT offers the first examples of parsimony dynamic sparse training because, in many datasets, it can retain network performance by percolating and significantly reducing the node network size.

Microglial Replacement and COURIER or SPIT for Neuronal Gene Editing
Authors: Renteln Michael
Published: May 2024

Adeno-associated viral (AAV) vectors can be used for gene delivery. AAV.CAP-Mac was recently developed; it can cross the blood-brain barrier and transduce cells throughout the CNS. However, some brain regions were not transduced in adult rhesus monkeys. Additionally, AAV vectors can only package 5 kb of DNA. Also, AAV vectors may be genotoxic and cytotoxic, especially at high doses. Finally, AAV vectors are very expensive to produce at sufficiently high titers for treatment. Off-the-shelf cell-based delivery systems wherein the cells can infiltrate the target tissue and be hyper-motile would be ideal. Also, mRNA-based gene editing would be a transient treatment, and thus be much safer.

Published: May 2024

Lap joints were friction stir welded in AA 7075-T6 at 1320 rpm and using two welding speeds: 70 mm/min and 120 mm/min. The temperature profiles of the weld zone were registered during the process; furthermore, the microhardness, tensile strength, and microstructure of the joints produced were examined.
This study brings new insights into the thermomechanical behavior of the material during the process. The peak temperature obtained with the lower welding speed (70 mm/min) is 10% higher than that obtained with the higher speed (120 mm/min). Moreover, a 5% increase in microhardness and a 6% increase in tensile strength were were observed increasing the welding speed. Addition-ally, the microstructure examination demonstrated that, by decreasing the welding speed, the larger interaction between the tool and the material results in a deeper stir zone due to the increased heat diffusion downwards to the material. This heat flow affects the thermal profile and influences the resulting mechanical properties of the welded joints.
Probiotic yeasts: a developing reality?
Authors: Tullio Vivian
Published: May 2024

Yeasts are gaining increasing attention for their potential health benefits as probiotics in recent years. Researchers are actively searching for new yeast strains with probiotic properties (i.e, Debaryomyces hansenii; Kluyveromyces marxianus; Yarrowia lipolytica; Pichia hudriavzevii; Torulaspora delbrueckii) from various sources, including traditional fermented foods, the human gut, and the environment. This exploration is expanding the pool of potential probiotic yeasts beyond the well-studied Saccharomyces boulardii. Research suggests that specific yeast strains possess properties that could be beneficial for managing conditions like inflammatory bowel disease, irritable bowel syndrome, skin disorders and allergy. Additionally, probiotic yeasts may compete with pathogenic bacteria for adhesion sites and nutrients, thereby inhibiting their growth and colonization. They might also produce antimicrobial compounds that di-rectly eliminate harmful bacteria. To achieve these goals, the approach that uses probiotics for human health is changing. Next-generation yeast probiotics are emerging as a powerful new approach in the field of live biotherapeutics. By using genetic engineering, scientists are able to give these tools specialized capabilities. However, most research on these probiotic yeasts is still in its early stages, and more clinical trials are needed to confirm their efficacy and safety for various health condi-tions. This review could provide a brief overview of the situation in this field.
What To Expect (and What Not) From Dual-energy CT Imaging Now and in the Future?
Authors: García-Figueiras Roberto
Published: May 2024

Dual-energy CT (DECT) imaging has broadened the potential of CT imaging by offering multiple postprocessing datasets with a single acquisition at more than one energy level. DECT shows profound capabilities to improve diagnosis based on its superior material differentiation and its quantitative value. However, the potential of dual energy imaging remains relatively untapped, possibly due to its intricate workflow and intrinsic technical limitations of DECT. Knowing the clinical advantages of dual-energy imaging and recognizing its limitations and pitfalls is neces-sary for an appropriate clinical use. The aims of this paper are to review physical and technical basis of DECT acquisition and analysis, to discuss advantages and limitations of DECT in dif-ferent clinical scenarios, to review technical constraints in material labeling and quantification, and to evaluate cutting-edge applications of DECT imaging, including artificial intelligence, qualitative and quantitative imaging biomarkers, and DECT-derived radiomics and radioge-nomics
Influence of Ambient Pressure on the Jet-Ignition Combustion Performance and Flame Propagation Characteristics in a Constant Volume Combustion Chamber

Published: May 2024

Based on a constant volume combustion chamber, the initial ambient pressure effect on combustion performance and flame propagation of the active and passive pre-chamber ignition systems were studied. Compared with the passive pre-chamber, the active pre-chamber can significantly expand the lean combustion limit, enhance the ignition and combustion performance, and speed up the combustion of the main combustion chamber. At slightly lean combustion conditions, the heat release performance has a positive correlation with the initial ambient pressure. As the premixed λ increases, the heat release performance and the initial ambient pressure begin to become negatively correlated. Ignition delay can be minimized by controlling the excess air coefficient in the pre-chamber close to the stoichiometric ratio. The high ambient pressure in the constant volume chamber greatly reduces the mixture entrainment ability of the jet flame at lean combustion conditions, thereby reducing the combustion speed and peak heat release rate.
Origins of Lunar Water Ice: Analyzing Isotope Signatures and Evidence from Satellite Observations
Authors: VUNNAM REDDY VARUN
Published: May 2024

The discovery of water ice on the moon has revolutionized our understanding of lunar science and has profound implications for future space exploration and habitation. Through a comprehensive analysis of remote sensing data, isotopic studies, and neutron detection experiments, this research elucidates the presence, distribution, and origins of lunar water ice. Radar observations from missions like Clementine and Chandrayaan-1 reveal distinct polar regions with elevated circular polarization ratios, indicative of volatile ice deposits. Spectral detections by instruments such as M3 and Diviner further confirm the presence of water ice in lunar-shadowed regions, with estimates suggesting reserves of up to 300 million tons at the poles. Neutron detection experiments on lunar orbiters like LRO provide additional evidence, detecting hydrogen signals consistent with water ice below the lunar surface. Isotopic analyses offer insights into the origin and evolution of lunar water ice, with comparisons to cometary and asteroidal sources. Proposed missions, such as Artemis-3 and Artemis-4, aim to collect samples from the lunar South Pole for detailed isotopic analysis, furthering our understanding of lunar water ice's composition and history. Scientific data, including the lunar bulk water content and estimated water ice reserves, underscore the significance of lunar water ice as a critical resource for future space exploration endeavors. Calculations estimating the total water-ice area and water abundance near specific lunar features provide valuable insights into the potential utilization of lunar water ice for sustained human presence on the Moon and beyond.

Simple summary
This reassessment of the findings from our Phase I/II study seeks to evaluate the effectiveness of SBRT for treating local intermediate-high risk prostate cancer in the absence of androgen-deprivation therapy due to patient’s refusal, with a median follow-up of 6.5 years. Our primary focus is on analysing the treated areas compared to recurrence patterns in the seven patients who experienced local relapse. Additionally, we provide updated data on late toxicities of grade 2 or higher, both genitourinary and gastrointestinal.

Abstract
Objectives: We investigated spatial patterns between primary and recurrent tumor sites and assessed long-term toxicity after dose escalation stereotactic body radiation therapy (SBRT) to the dominant intraprostatic nodule (DIN).
Materials and methods: In 33 patients with intermediate-high risk prostate cancer (PCa), doses up to 50 Gy were administered to the DIN. Recurrence sites were determined and compared to the original tumor development sites through multiparametric MRI and 68Ga-labelled prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (68Ga-PSMA-PET/CT) images. Overlap rates, categorized as 75% or higher for full overlap, and 25-74% for partial overlap, were assessed. Long-term toxicity is reported.
Results: All patients completed treatment, with only one receiving concomitant androgen deprivation therapy (ADT). Recurrences were diagnosed after a median of 33 months (range: 17-76 months), affecting 13 out of 33 patients (39.4%). Intraprostatic recurrences occurred in 7 patients (21%), with ≥ 75% overlap in two, a partial overlap in another two, and no overlap in the remaining three patient. Notably, 5 patients with intra-prostatic recurrences had synchronous bone and/or lymph node metastases, while six patients had isolated bone or lymph node metastasis without intraprostatic recurrences. Extended follow-up revealed grade 2 or higher late GU and GI toxicity in 18% (n=6) and 6% (n=2) of the patients.

Conclusions: Among patients with intermediate-high risk PCa undergoing focal dose-escalated SBRT without ADT, DIN recurrences were infrequent. When present, these recurrences were typically located at the original site or adjacent to the initial tumor. Conversely, relapses beyond the DIN and in extra-prostatic (metastatic) sites were prevalent, underscoring the significance of systemic ADT in managing this patient population.

Advances in knowledge: focal dose escalated prostate SBRT prevented recurrences in the dominant nodule, however extra-prostatic recurrence sites were frequent.

The antimicrobial peptide LRGG (LLRLLRRGGRRLLRLL-NH2) was designed and chemically synthesized in a study conducted by Jia et al. Gram-negative bacteria were found to be sensitive to LRGG and exhibited a high therapeutic index. Genetic engineering methods were used to create the prokaryotic fusion expression vector pQE-GFP-LRGG, and the resulting corresponding fusion protein GFP-LRGG was subsequently expressed and purified. The precursor GFP was then removed by TEV proteolysis, and pure LRGG was obtained after another round of purification and endotoxin removal. The prokaryotic-expressed antimicrobial peptide LRGG displays a broad-spectrum antibacterial effect on gram-negative bacteria and can eliminate 99.99% of E. coli within 100 minutes at the minimal MIC concentration. Compared to the chemically synthesized LRGG, the prokaryotic-expressed LRGG exhibits similar temperature, pH, salt ion, serum stability, and cell selectivity. Furthermore, prokaryotic-expressed LRGG showed excellent therapeutic effects in both the infection model of cell selectivity and no embryotoxicity in a Galleria mellonella infection model. The mechanism by which LRGG causes bacterial death was found to be disruption of Gram-negative cell membrane.
Instruments to Assess Family Nurse’s Workload: Scoping Review
Authors: Dias António , Araújo Beatriz , Jesus Élvio
Published: May 2024

Background: The importance of knowing the workload of family nurses lies essentially in the possibility of improving health outcomes, care processes and the nurse’s professional life. There is a lack of studies that fully describe nursing workload in primary care, particularly, in the context of family health nursing, and the ideal metrics to be used remains unknown, making it impossible to characterize and therefor provide the necessary insight to acknowledge the different contributions of several aspects that embodies the global workload of family nurses. The objective of this scoping review was to map the known evidence and characterize the instruments used to assess the workload of family nurses. Methods: Scoping review, according the Joanna Briggs Institute proposed methodology for scoping reviews, consisting of 3 research stages: 1) initial research in Medline and CINHAL; 2) extended search, using keywords and search terms, in the following databases: JBI, CINAHL Complete, MEDLINE, Cochrane and Scopus; 3) Search the reference list of the selected articles. No time limit was defined. Results: Fourteen studies referring to ten as-sessment instruments were included. Nine of them analyze workload as a dimension of a broader instrument, and two studies refer to an instrument that focuses exclusively on workload. Con-clusions: The diversity of professional competencies and contexts, the conceptual complexity of workload and the absence of an theoretical framework, makes it difficult to identify consensual instruments to assess the workload of family nurses. This study was registered in Open Science Framework® with the following registration (https://osf.io/3k6vr).

Published: May 2024

Natural risks encompass a range of disasters and dangers, requiring comprehensive management through assessments, anticipations, and advanced alert systems. Our specific focus is on landslides in challenging terrains. The evaluation of landslide risks employs sophisticated multicriteria models, such as the weighted sum approach, integrating qualitative parameters. Despite the challenges of the rugged terrain in Northern Algeria, it paradoxically hosts a dense population attracted by valuable hydro-agricultural resources. Our research is dedicated to studying landslide risks in these areas, particularly in the Mila region, with the aim of constructing a statistical model integrating considerations of both danger and vulnerability. This complex process identifies threats and their determining factors, including geomorphology and socio-economic conditions. The result is a valuable tool for effective risk management, strengthening safety and resilience against natural disasters. By understanding the intricate interplay of geological, environmental, and social elements, our research can contribute to the development of targeted interventions, fostering a more resilient community in the face of natural adversities.
Gastropod Allergy: A Comprehensive Narrative Review
Authors: Mederos-Luis Elena , Poza-Guedes Paloma , Pineda Fernando , Sánchez-Machín Inmaculada , González-Pérez and Ruperto
Published: May 2024

Food allergies have increased significantly in recent decades, with shellfish being a leading cause of food allergy and anaphylaxis worldwide, affecting both children and adults. The prevalence of shellfish allergies is estimated to be approximately 0.5-2.5% of the general population, varying significantly by geographical location, age, and consumption habits. Although mollusk consumption has risen, the prevalence of mollusk allergies remains unknown. While extensive research has focused on crustacean allergies, mollusk allergies, particularly those related to gastropods, have received comparatively less attention. Clinical manifestations of shellfish allergy range from localized symptoms to life-threatening systemic reactions, such as anaphylaxis. Notably, severe bronchospasm is a predominant clinical feature in cases involving gastropods. Several allergens have been identified in mollusks, including paramyosin, tropomyosin, and sarcoplasmic calcium-binding protein. In gastropods, documented allergens include tropomyosin, paramyosin, the heavy chain of myosin, and Der p 4 amylase. Diagnosis typically involves a thorough clinical history, skin testing, in vitro quantification of immunoglobulin (Ig) E, and confirmation through oral challenge, although the latter is reserved for selected cases. This review highlights the limited research on gastropod allergy, the identified allergens to date, and the necessity for further investigations to better understand the implications of shellfish allergy within this class.
Primordial Black Holes in the Pre-Inflationary Period, the Probabilities of Their Occurrence Taking Into Account Quantum-Gravitational Corrections, and Some Cosmological Implications
Authors: Shalyt-Margolin Alexander
Published: May 2024

In the last decades the primordial black holes ({\bf pbhs}) have attracted much attention of cosmologists and astrophysicists. This is associated with origination of such black holes in the early Universe as a result of a gravitational collapse of the high-density matter, making them natural ''detectors'' of the processes involved. In inflationary cosmology of particular importance are {\bf pbhs} originated during the pre-inflationary period. And, since they are small and generated at the energies close to the Planck energies, for them we should take into consideration the quantum-gravitational corrections ({\bf qgcs}). In turn, these corrections change (shift) the inflationary parameters. The paper presents a study of the above-mentioned shifts with regard to these corrections for different scenarios. It is shown that probabilities of occurrence of the {\bf pbhs} under study with due regard for the given {\bf qgcs} are rising as compared to the semiclassical consideration. Besides, high-energy deformations of Friedmann Equations created on the basis of these corrections have been derived for different patterns. Conclusion contains the general remarks concerning the above-mentioned {\bf qgcs} for cosmological parameters and perturbations due to inflation; the steps for their investigation are outlined and the key problems of such a study are formulated.
Remote Coastal Weed Infestation Management Using Bayesian Networks

Published: May 2024

The increasing prevalence of species that are detrimental to biodiversity is a major concern, particularly for managers of National Parks. To develop effective programs for controlling weeds, it is essential to have a thorough understanding of the extent and severity of infestations, as well as the contributing factors such as temperature, rainfall, and disturbance. Predicting these factors on a regional scale requires models that can incorporate a wide range of variables in a quantifiable manner, while also assisting with on-ground operations. In this study, we present two Bayesian Network models specifically designed for six significant weed species found along the southern coast of Australia. Our models are based on empirical data collected during a coastal weed survey conducted in 2015 and repeated in 2016. We applied these models to the coastal national parks in the isolated and pristine East Gippsland region. Importantly, the prediction models were developed at two different spatial scales that directly corresponded to the scale of the observations. Our findings indicate that coastal habitats, with their vulnerable environments and prevalence of open dune systems, are particularly susceptible to weed infestations. Moreover, adjacent regions also have the potential for colonization if these infestations are not effectively controlled. Climate-related factors play a role in moderating the potential for colonization, which is a significant concern for weed control efforts in the context of global climate change.

Adaptive artificial viscosity in calculations via non-uniform grids
Authors: Gasilov Vladimir Anatolievich , Krukovskiy Alexander Yur’evich , Popov Igor Viktorovich , Lepe Nikolai Leonidovich
Published: May 2024

The paper concerns with some adaptive artificial viscosity technique which is proposed for the numerical solution of gas-dynamic problems using non-uniform difference grids. The construction of a corresponding conservative difference scheme is developed for one-dimensional problem formulations. We’ve estimated the viscosity value bounds which give sufficient conditions for preserving a monotonicity property of the solution. The estimations take into acсount both the heterogeneity of gas-dynamic quantities (density, pressure, internal energy...) in the flow region, and the unevenness of the computational grid. Approbation of the modified methodology is carried out by calculating a number of well-known test problems. Computational experiments demonstrate a possibility of high-precision calculations via using grids incorporating adjacent computational cells with a great difference in sizes.

A hangos olvasás hibajavításának mintázatai szemkamerás és akusztikai, fonetikai vizsgálatok tükrében
Authors: Bóna Judit , Steklács János
Published: May 2024

A hangos olvasás folyamatossága és tempója az egyik legfőbb mérőeszköze az olvasási képességnek. Az olvasás folyamatossága mellett vizsgálható az is, hogy milyen típusú hibákat vétenek a gyermekek a hangos olvasás közben. Ezeknek a hibáknak a javítása valószínűleg más stratégiákat igényel, mint a spontán beszédben előfordulóké. A jelen tanulmány ezt az olvasás során végbemenő hibajavítási folyamatot vizsgálja akusztikai fonetikai és szemkamerás módszerrel. Ez utóbbi nóvum nemcsak a hazai, hanem a nemzetközi szakirodalomban is. Az eredmények azt mutatják, hogy a hiba javításának nehézsége mind a beszédben, mind a szemmozgások jellemzőiben megmutatkozik: a nehezebben javítható hibák nemcsak hosszabb javítási idővel járnak együtt a beszédben, hanem ilyenkor a szemmozgások is összetettebbé válnak. Az eredmények hozzájárulhatnak az olvasástanítás hatékonyságának a növeléséhez, az olvasástechnika fejlesztésének a korszerűsítéséhez.

A gyermekek személyiségfejlődésére különösen hátráltató hatással van a verbálisan agresszív légkör. Az iskola az egyik olyan hely, ahol a gyerekek a legtöbb időt töltik, így ez az intézmény befolyásolja leginkább a diákok jellemfejlődését. Ezért döntő szerepe van annak, hogy tanárként hogyan kommunikálunk, miként oldjuk meg a konfliktusokat a diákokkal, és ezáltal milyen mintát adunk nekik a felnőtt, érzelmileg intelligens beszédmódról. Létfontosságú, hogy az olyan családokból érkező gyermekek, akik ezt a mintát otthon nem kapták meg, az oktatásban új kommunikációs eszközökhöz jussanak. Ezt igyekszik támogatni annak a tréningnek a bemutatása, amely az erőszakmentes kommunikáció alapjait ismerteti meg a saját élményű tanulás segítségével egy csoportnyi kamasz gyerekkel. A bemutatott gyakorlatok kipróbálása hozzájárulhat ahhoz, hogy az osztályban egy konfliktusokat eredményesen kezelni tudó és egymással együttműködő közeg jöjjön létre.

Kategóriák és társas jelentések: roma diákok beszédmódjainak elemzése a heteroglosszia-elmélet alapján
Authors: Bernadett Jani-Demetriou
Published: May 2024

A tanulmány magukat kétnyelvű romaként meghatározó gyerekek beszédmódjait vizsgálja. Az elemzés alapját a heteroglosszia (Bahtyin 1986) elmélete adja, amely a beszélői perspektívát érvényesíti. Jelen elemzés arra fókuszál, hogy a gyerekek kétnyelvűsége milyen tanári nyelvi ideológiák mentén értékelődik, a társas közeg hogyan alakítja a (többnyelvű) megszólalásokat, illetve a beszélők nyelvi erőforrásai milyen társas jelentéseket indexálnak. A hangok elemzésével megismerhetővé válnak az egyének kulturálisan meghatározott, az interakciókban megjelenített identitásai. Az adatgyűjtés megfigyeléssel és tanári interjúk készítésével a tanár-diák interakciókban jelentkező feszültségekre (Hong et al. 2017) koncentrálódott. Az interakcióban megjelenő feszültségek indikálják a közösségben létező nyelvi ideológiákat, amelyek alakulása a gyerekek tanulására is hatással van; az, ahogy a tanárok látják őket, befolyásolja a pedagógiai eszközök kiválasztását a gyerekek tanulásának támogatására.

A pápaság és a császárság küzdelme – a fogalmi terminologizálódás egy tankönyvcsaládban
Authors: Anna Magdolna Fésű
Published: May 2024

A tanulmány egy történelem-tankönyvcsaládban két kiválasztott történelmi vezetői tisztségnév – pápa, császár – fogalmának konstruálódását vizsgálja két tankönyv szövegén keresztül. A kutatás alapvető kérdése, hogy a szövegkörnyezetnek köszönhetően kialakul-e a kifejezéseknek olyan definíciója, amely terminusértékkel rendelkezik, továbbá az, hogy a középiskolai tankönyvekben szövegszinten hogyan épül fel a két fogalom a diákok számára, és milyen további fogalmak segítik a terminologizációs folyamatot. A tanulmány elméleti keretét a funkcionális kognitív nyelvészet adja, dinamikus modellt kínál az elemzéshez. A kiválasztott fogalmak konstruálódásának vizsgálata korpuszalapon történik. A korpusz azokat a szövegrészeket tartalmazza, amelyek közvetlenül kapcsolódnak a tisztségnevekhez. A tanulmány a szövegszinten megjelenő fogalmi kapcsolatokat fogalmi háló formájában, vizuálisan is ábrázolja.

—The three-dimensional dynamic problem solution of the theory of elasticity as it applies to modeling of all types of seismic waves propagating in real geological media is considered. The elements of the 3D forward modeling algorithm based on the spectral element method (SEM) for the numerical solution of the problems posed are presented. The SEM’s main characteristics (high order spatial discretization, explicit time integration scheme) and its advantages are compared with the classical finite element method (FEM). Distinctive features of massively parallel implementation of this algorithm on Nvidia GPU using CUDA (Compute Unified Device Architecture) are considered. The efficiency of parallelization on hybrid systems at different orders of SEM and parameters of the numerical scheme of time integration is analyzed. Results of solving a three-dimensional problem of modeling seismic wave propagation in a heterogeneous geological medium with faults and strongly varying (vertically and horizontally) properties of the investigated layers are presented. A highly detailed digital geological model constructed for one of the petroleum fields in the Arctic region using Petrel, the world’s most popular geological modeling tool, is used as input datasets. The problem was solved on a mesh of hexahedral elements in 3D to perform efficient SEM calculations in the CAE Fidesys software developed earlier with the authors participation for engineering simulations (strength analysis, etc.). The derivation of the model was based on the typical seismogeological conditions of Western Siberia so that the modeling allows investigating look-ahead capabilities of numerous seismic exploration methods for an in-depth study of major oil-and-gas-bearing complexes in this region. The prospects of model implementation for other candidate regions with different geological structure are equally promising. Outputs of the full-waveform seismic modeling is stored in the standard SEG-Y format currently widely used worldwide in industry for seismic data processing. The obtained synthetic seismograms and seismic wave fields are analyzed. The practical significance of the conducted research whose results can be utilized in the future for solving a wide range of applied tasks for regions with different geological conditions is deduced.

This study assessed the effects of high-fibre olive pomace (OP) and exogenous multi-enzyme (phytase, cellulase, and xylanase) on broiler chickens' growth performance, internal organs, intestinal morphology, blood traits, lipid profile of serum, and health. 300 one-day-old Ross 308 chicks were randomly divided into six groups using a 2 × 3 factorial design with 0 and 0.5g/kg multi-enzyme and 0, 5, and 10% olive pomace. The diet was primarily based on corn and soybean meal. The experiment was carried out in three stages: starter, grower, and finisher. The results indicated that the inclusion of OP at both 5% and 10% levels did not negatively impact broilers' performance (P > 0.05). However, supplementing the diet with multi-enzyme significantly increased feed consumption, body weight, and weight gain (P < 0.05). Furthermore, chickens offered with 10% OP + multi-enzyme exhibited the best performance compared to other experimental groups. The mortality rate also showed a non-significant decline of almost 5% (P > 0.05). Additionally, administration of OP and multi-enzyme or a combination of them to the broilers' diet improved serum lipid profile and liver enzyme activity (P < 0.05) and did not affect the relative weight and length of internal organs, and intestinal histomorphology (P > 0.05). In conclusion, simultaneous use of multi-enzyme and diet containing olive pomace could improve the serum lipid profile, liver enzyme activity, and overall health without adverse effect on broilers performance.
