Napjainkban a digitális kultúra új környezetet teremtett az iskolákban is. Az intézmények nagy szerepet játszanak a digitális kompetencia kialakításában. Ebbe beletartozik az intézmények informatikai eszközökkel való ellátottsága, a korszerű eszközhasználat, a pedagógusszerep szükséges változása, a tananyag tartalmához igazodó módszerek kiválasztása és alkalmazása is. Felmérésekből tudjuk, hogy összefüggés mutatható ki az informatikai infrastruktúra fejlesztése és a tudáseredmények hatékonyságának a növekedése között. A 21. század diákjainak a digitális eszközök használata már magától értetődő, így érdemes ezek motivációs erejére építeni. A tanulmány az anyanyelvi órákon is használható IKT-eszközökből és programokból mutat be néhány jól adaptálható példát, amelyek hatodik osztályban segíthetik a tudás rendszerezését, bővítését, illetve pedagógusokat szólaltat meg az eszközhasználattal kapcsolatban.

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.

Abstract
—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.

Abstract

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.

Abstract

Background
Radiation-induced fibrosis (RIF) is a debilitating sequelae of radiation therapy that has been shown to improve with topical treatment with the iron chelator deferoxamine (DFO). We investigated whether DFO exerts this effect through attenuation of ferroptosis, a recently described iron-dependent pathway of cell death.
Methods
Adult C57BL/6J mice were treated with topical DFO or ferrostastin-1 (Fer-1) and irradiated with 30 Grays of ionizing radiation to the dorsal skin to promote development of chronic RIF. Immunofluorescent staining with 4-hydroxynonenal (4-HNE) antibody was carried out directly following irradiation to assess ferroptosis activity. Perfusion testing with laser Doppler was performed throughout the healing interval. Eight weeks following radiation, dorsal skin was harvested and analyzed histologically and biomechanically.
Results
Immunohistochemical staining demonstrated lower presence of 4-HNE in non-irradiated skin, DFO-treated skin, and Fer-1-treated skin compared to irradiated, untreated skin. DFO resulted in histological measurements (dermal thickness and collagen content) that resembled normal skin, while Fer-1 treatment yielded less significant improvements. These results were mirrored by analysis of extracellular matrix ultrastructure and biomechanical testing, which recapitulated the ability of topical DFO treatment to alleviate RIF across these parameters while Fer-1 resulted in less notable improvement. Finally, perfusion levels in DFO treated irradiated skin were similar to measurements in normal skin, while Fer-1 treatment did not impact this feature.
Conclusions
Ferroptosis contributes to the development of RIF and attenuation of this process leads to reduced skin injury. DFO further improves RIF through additional enhancement of perfusion not seen with Fer-1.

Abstract

Growth curve parameters in chickens can be affected by genetic and environmental factors. This study estimated the growth curve parameters of Ovambo (OV) and Black Australorp x Ovambo (BAO) chickens under a commercial (COM) and a Moringa oleifera leaf meal-containing (MOLM) diet. Thirty-two (32) BAO and 36 OV chicks were randomly allocated to eight pens and then the pens were randomly allocated the two diets giving rise to four treatment groups (BAO-COM; BAO-MOLM; OV-COM; and OV-MOLM). Chicks were weighed in groups of 4 from weeks 1–4; from 5–20 weeks chickens were individually weighed. The Logistic, Gompetz, von Bertalanffy and Richards functions were fitted to the data and the Gompertz function was the best fitting based on RMSE, AIC and BIC. The maturing rates, mature weights (g), age at inflection (d) and average daily gain (ADG) (g/d) were as follows: BAO-COM (0.0222 ± 0.0025; 3197.9 ± 196.5, 63.3, 25.8); BAO-MOLM (0.0142 ± 0.0036; 3783.4 ± 1031.3, 103.2, 17.3); OV-COM (0.0241 ± 0.0031; 2605.7 ± 159.0, 58.7, 22.3); and OV-MOLM (0.0159 ± 0.0037; 2952.9 ± 641.0, 95.5, 15.7), respectively. The results imply that the inclusion of M. oleifera led to higher mature sizes, but reduced the maturing rates and ADG compared to the commercial diet.

Abstract

In the context of regenerative agriculture (RA) and sustainability in lowland rice agroecosystems, inefficient resource use leads to reduced agricultural output and significant greenhouse gas emissions (GHG), particularly methane from flooded paddy fields. Adopting regenerative practices such as precision nutrient and water management, conservation tillage, and crop diversification can enhance soil health, reduce emissions, and improve productivity. The adoption of sustainable agricultural practices aligns with several United Nations Sustainable Development Goals (SDGs), including SDG 2 (zero hunger), SDG 13 (climate action), and SDG 15 (life on land). By promoting climate-smart agriculture, regenerative practices in rice farming can contribute to mitigating climate change effects, ensuring food security, and conserving biodiversity. In this scholarly investigation, we explore the efficacy of resource conservation technologies (RCTs) as nature- based solutions to enhance carbon storage, mitigate GHG emissions, and improve energy efficiency within rice-based cropping systems. Our study revealed that all resource conservation treatments led to increased system productivity and soil organic carbon compared to conventional practices. Among these treatments, zero-tillage exhibited the highest effectiveness in terms of carbon sequestration, with a rate of 0.97 Mg ha− 1y− 1. Zero-tillage consistently demonstrated the highest energy savings, ranging from 52.0–67.8% across analyzed seasons, and emerged as the most effective nature-based solution, with lower greenhouse warming potential compared to conventional practices. Implementing zero tillage reduces global warming potential, carbon emissions, and greenhouse gas intensity compared to conventional methods. Our findings support zero tillage and green manuring as effective strategies to enhance soil organic carbon levels, reduce emissions, and improve crop productivity in lowland rice-green gram cropping systems, fostering sustainable and climate-friendly agriculture. These findings provide valuable insights into nature-based solutions and resource conservation practices, addressing climate change mitigation, carbon sequestration, energy efficiency, and energy savings in rice-based cropping systems, promoting a more sustainable future.

Abstract

Detecting trace amounts of harmful bacteria and nanoscale biomarkers is essential for early diagnosis and preventing food poisoning and various diseases. Hindered by limited sensitivity and speed due to dilute samples, conventional detection methods, such as cultivation techniques and immunoassays, are expensive and time-consuming. In contrast, optical condensation using photothermal convection and bubbles facilitates rapid transport and dense assembly of dispersoids toward the observation area; however, its efficiency on two-dimensional substrates remains restricted. Here, to develop a more sensitive and rapid detection method using optical condensation, we introduce a metallic thin film-coated optical fibre module that serves as a photothermal source, generating convection and bubbles at the fibre tip. This leads to optical condensation at three-dimensionally arbitrary positions within the liquid. Notably, when the optical fibre module is positioned away from the substrate, 103-105 bacteria and microparticles in 20 μL liquid sample can be assembled at the fibre tip within 60 s. Furthermore, the assembly efficiency increases more than 10-fold, in comparison with the conventional two-dimensional photothermal assembly, exceeding 10% of all the disperoids due to horizontal and vertical convections from the fibre tip. Additionally, when the fibre module is placed on the substrate, target objects can be assembled not only at the fibre tip but also around the side wall of the fibre. Therefore, our findings demonstrate a significant enhancement in detection capabilities. This discovery paves the way for novel applications in bioanalytical technology, drug delivery systems, and material engineering.

Published: May 2024

Abstract

The structural and electronic properties of XGeCl3 (X = K, Rb) were calculated under hydrostatic pressure from 0 to 8 GPa using density functional theory (DFT). It is used Projector Augmented Wave (PAW) method which describes electron-ions interaction. The exchange-correlation functional energy functional was computed using Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation (GGA). It was observed that the lattice parameters and bond length of XGeCl3 (X = K, Rb) compounds examined by introducing hydrostatic pressure range of 0 to 8 GPa decreased. The band gap of XGeCl3 (X = K, Rb) compounds reveals the direct band gap at the R symmetry point in the Brillouin Zone. These compounds exhibit semiconductor behavior with narrow band gap at ambient pressure. The electronic band gap (Eg) of KGeCl3 and RbGeCl3 is calculated 0.5802 (eV) and 0.657 (eV) at 0 GPa, respectively. As expected, hydrostatic pressure reduced the band gap, and the metallic character was detected at 5 GPa for both structures. The compounds described in this paper were evaluated for the visible energy area, which might be viable candidates for optoelectronic applications, and turned out to exhibit the direct electronic band.

Abstract

Background
The Pediatric Quality of Life Inventory™ (PedsQL™) Family Impact Module, a valuable assessment tool for health-related quality of Life (HRQoL), is not accessible in Swahili. This study evaluated the construct validity of the PedsQL™ Family Impact Module in assessing HRQoL for Swahili speakers in Eastern Africa, Tanzania, particularly focusing on families of chronic congenital heart disease (CHD) with both operated and unoperated children.
Methods
The cross-sectional study involved primary caregivers at a national referral cardiac centre. Descriptive statistics for continuous and categorical variables were employed. Translation and cross-cultural adaptation of the Family Impact Module (FIM) were conducted. The "known-groups method" was used to establish construct validity, while internal consistency reliability was assessed using Cronbach's alpha coefficient at a value of ≥ 0.70. HRQoL was measured using a Likert linear analogue scale. Mean scores, standard error of the mean (SEM) and Cohen's d-effect size were used to summarize the results. Group comparisons were made using a t-test, and predictors of HRQoL were analysed using generalized linear models. The significance level was set at a p < 0.05.
Results
The Swahili version of the FIM for internal consistency showed high reliability (α = 0.99). The module was applied to 204 primary caregivers and was mostly answered by mothers, 74.0% of whom had an average of 9.5 + 3.6 years of schooling. The socioeconomic status (SES) of families was moderate at 0.68 ± 0.17 but statistically significantly higher in the operated group (0.71 ± 0.14; p-value < 0.001): This group also had a significantly higher HRQoL (91.5 vs. 84.7, d = 0.60, p-value < 0.001 and a much better emotional well-being (d = 0.71). Notably, the overall family functioning, particularly the family relations and communication, did not differ between groups. SES and operative status were the only significant predictors of the caregiver’s HRQoL, with p < 0.001. Principally, QoL was not predicted by the child’s age, CHD severity, number of cardiac lesions, medication use, or the parent's level of education.
Conclusion
The study validated the Swahili PedsQL™ Family impact module for chronic illnesses in the Swahili-speaking population. It highlighted improved quality of life due to cardiac treatment and ongoing issues in communication, family dynamics and functioning post-surgery. Recommendations included health care providers addressing these gaps proactively, advocating community support for affected families and caregivers prioritizing positive family relationships to enhance overall well-being.

Abstract

Heavy metal pollution poses a significant environmental challenge, adversely impacting global crop yields and posing health risks to humans. Cadmium (Cd), a non-essential and highly phytotoxic metal, poses substantial harm to overall plant metabolism even at minimal concentrations. The current research aimed to evaluate the beneficial impacts regarding priming of seeds of trehalose upon the development of cells able to photosynthesis traits, biochemical, and physiological and antioxidant defense systems among two variety of maize (FH-1046 and FH-5724) under Cd stress. For this purpose, a pot experiment was carried out in the University of Education Lahore, Faisalabad campus. After two weeks, growth parameters, biochemical and Cd concentration were examined. Results revealed that Cd significantly reduced the growth and maize variety FH5427 showed better growth as compared with FH1046. Chlorophyll contents also decreased under Cd stress and trehalose improved the photosynthetic efficiency under Cd stress. Carbohydrates and protein contents also reduced under Cd stress and trehalose significantly ameliorated the Cd stress in both maize varieties. Enzymatic and non-enzymatic antioxidants were greater under Cd stress and lower in trehalose treated group. This clearly showed the Cd alleviation potential of trehalose in maize plants. Trehalose also inhibits the movement of Cd into shoot from root system. Results also showed that Cd stress significantly decreased the growth, photosynthetic efficiency, and biochemical characteristics of two maize cultivars. However, the seeds treated with trehalose solution significantly reduce the impact of Cd stress. Moreover, it also enhances photosynthetic activity, enzymatic activities in requisites of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) and decreases the reactive oxygen species. The study suggests that priming maize seeds with trehalose could be effectively utilized in agricultural settings to enhance plant tolerance to cadmium stress.
Finite-time tracking control of tanker/UAV formation with hose connection based on constraint space

Published: May 2024

Abstract

This paper investigates the problem of finite-time tracking control for refueling formations under hose connection constraints subsequent to the docking of a receiving unmanned aerial vehicle (UAV) and a tanker in autonomous aerial refueling missions. The inclusion of hose connections not only imposes constraints to prevent disconnection but also introduces disturbances to the UAV. Initially, a model for the tension constraints at the hose-UAV connection point is first introduced, transforming complex hose constraints into relative state constraints between the UAV and the tanker. Meanwhile, a modified barrier function that incorporates the UAV's state and formation tracking errors is designed to deal with the decomposed hose constraints. Furthermore, an extended state observer is deployed to estimate external complex disturbances. Subsequently, leveraging dynamic surface control techniques, a finite-time control scheme is proposed to meet the dual requirements of preventing hose disconnection and achieving rapid convergence in the refueling formation. Compared to traditional hose constraint solutions, this scheme enhances the safety of refueling formation systems. Both theoretical proofs and simulation results substantiate the efficacy of the proposed control scheme.

Abstract

A simple synthesis of novel N-(2-[N’-acetamidomethyl])benzanilides derivatives from 2-nitrobenzaldehyde in a four steps process is described. The 1H-NMR and 13C-NMR spectra were meticulously analyzed to characterize their structure and it was observed that derivatives with an ortho-substituted phenyl group exhibited detectable atropisomerism. The ADME/toxicity analyses was performed and several of these acetamidobenzanilides were tested in vitro against the epimastigote form of Trypanosoma cruzi, demonstrating significant activity.
