Published: August 2024

Tidal lowland is a marginal land characterized by low pH, deficient nutrients, and salinity. Despite these challenges, El Niño phenomenon often occurs during the second planting season, resulting in long droughts. However, tidal lowland must be used for cultivation due to the need for rice and the land should be treated accurately. Therefore, this research aimed to address the issues by improving the efficiency of rice cultivation on tidal lowland through precision farming practices. A survey and land analysis were conducted in tidal lowland of B typology in Delta Saleh, Indonesia, from March 2023 to June 2023. In this precision farming practice, water management was highly prioritized, starting from tertiary channels such as optimizing sluice gate operations and monitoring water levels in channels and groundwater. Additionally, pH, CEC, and C-Organic analysis were also carried out in rice cultivation, as showed by the equation Y = 0.15 - 0.001 pH + 0.000 CEC + 0.000 C-Organic. The highest production yield was 2.05 tons/ha in P5, with the SEW-10 value during cultivation activities being 778 cm and the number of days above -10 reaching 84. Moreover, the efficiency of rice cultivation was improved through precision agricultural practices by using valve sluices and levees.

Given the current challenges and issues, such as the risks and threats inherent in the use of the internet and smart devices, it is essential to be competent in digital security and behave ethically in digital environments. Therefore, the study aimed to design and validate the COSEDI instrument based on the European Framework for Digital Competence for Citizens (DigComp). To achieve this, an analysis based on structural equation modelling (PLS-SEM) was conducted, employing a non-experimental and quantitative methodology. The representative sample consisted of 497 teachers from the public education system in Andalusia, with a pilot study involving 60 teachers, who were excluded from the final analysis. The results demonstrate the validity and reliability of the instrument by illustrating the causal relationships between the constructs of data and privacy protection, device protection, environmental protection, and health and well-being protection. This is further supported by the inclusion of observed variables, as evidenced by the values of factor loadings and significance. Thus, the model supports the idea that the four latent variables influence each other, with the relationship between data and privacy protection and device protection being the strongest and most significant, while the weakest relationship is observed between the protection of personal data and environmental protection.
Ante los retos y desafíos actuales, como son los riesgos y amenazas inherentes al uso de internet y los dispositivos inteligentes, se hace indispensable ser competentes en seguridad digital y comportarnos éticamente en los entornos digitales. Por ello, el estudio ha tenido como objetivo diseñar y validar el instrumento COSEDI, basado en el Marco Europeo de Competencias Digitales para la Ciudadanía (DigComp). Para ello, se ha realizado un análisis basado en el modelado de ecuaciones estructurales (PLS-SEM), con una metodología de corte no experimental y cuantitativa. La muestra representativa ha quedado conformada por 497 profesores del sistema educativo público de Andalucía. Los resultados muestran la validez y fiabilidad del instrumento a través de la demostración de las relaciones causales entre los constructos de protección de datos y privacidad, protección de dispositivos, protección medioambiental y protección de la salud y el bienestar, así como la pertenencia de las variables observadas que los conforman, a través de los valores de las cargas factoriales y significancia. Por tanto, el modelo avala la idea de que las cuatro variables latentes tienen una influencia las unas sobre las otras, siendo la relación entre la protección de datos y privacidad y la protección de dispositivos la más fuerte y significativa, mientras que la más débil se da entre la protección de datos personales y protección medioambiental.

Published: August 2024

In the field of science education, there is a lack of neuroeducational guidelines and resources. This is because it is a relatively new area of study. It is important to investigate whether these guidelines and resources can improve university-level teaching. To address this issue, a constructivist neuroeducational approach was taken using inquiry-based learning. This involved the integration of various resources into a set of activities for 77 future professionals in primary education.
The proposal’s effectiveness was evaluated using three questionnaires: 1) two ad-hoc content questionnaires and 2) a reliable (αCronbach = 0.968) and validated (KMO = 0.934) neuroeducational scale based on Likert scale by measuring the main dimensions. The study was based on a pre-experimental pretest-posttest design using Wilcoxon non-parametric tests, achieving a large effect size (mean values: pretest = 4.17 ± 1.40; posttest = 6.55 ± 0.53; z = 7.568; p < 0.001; r = 0.862), highlighting the importance of emotions in enquiry using novelty, which enhanced attention and the development of executive functions, resulting in an effective, feasible and practical proposal.
En la enseñanza de las ciencias existe una ausencia de orientaciones neuroeducativas y de recursos afines por ser un área reciente, siendo necesario comprobar si pueden mejorar la enseñanza universitaria. Para ello, se realizó una propuesta neuroeducativa constructivista a través de un aprendizaje basado en la indagación, en donde se utilizaron diferentes recursos integrados en una serie de actividades, para 77 futuros profesionales de la educación primaria.
La efectividad de la propuesta se valoró mediante el empleo de tres cuestionarios: 1) dos cuestionarios ad-hoc de contenido y 2) otro basado en una escala neuroeducativa tipo Likert fiable (αCronbach = 0,968) y validada (KMO = 0,934), en donde se midieron las dimensiones más notorias. El estudio se basó en un diseño pre-experimental pretest-postest utilizando pruebas no paramétricas de contraste (Wilcoxon), logrando un gran tamaño de efecto (valores medios: pretest = 4,17 ± 1,40; postest = 6,55 ± 0,53; z = 7,568; p < 0,001; r = 0,862), destacándose la importancia de las emociones en la indagación, utilizando la novedad, lo que potenció la atención y el desarrollo de las funciones ejecutivas, dando como resultado una propuesta efectiva, viable y práctica.

Objectives: The study aimed to evaluate the surgical results of antireflux surgery (ARS) in neurologically impaired children with gastroesophageal reflux disease (GERD) who underwent surgery in our clinic.
Patients and methods: This retrospective study included 84 children (50 males and 34 females; mean age: 44.4±49 months; range, 2 to 224 months) between January 2011 and October 2016. Data on patient demographics, indications for surgery, preoperative symptoms, preoperative diagnostic tests, surgical procedures, complications, and reoperations were collected.
Results: The mean follow-up period was 17.9±22.5 months. The most frequent underlying pathology was cerebral palsy (67.4%). The main indication was recurrent aspiration pneumonia (77.1%). Preoperative diagnostic tests included an upper gastrointestinal contrast study (78.6%), gastric emptying study (69%), 24-h pH monitoring (21.4%), and endoscopy (8.3%). Surgical procedures included laparoscopic Nissen fundoplication (LNF) and gastrostomy in 61 patients, only LNF in 12 patients, and open Nissen fundoplication and gastrostomy in five patients. Laparoscopic Nissen fundoplication and pyloroplasty were performed in three patients, and LNF, gastrostomy, and pyloroplasty were performed in three patients. In the postoperative period, 58.3% of patients were free of symptoms. Postoperative complications occurred in six patients. A redo Nissen fundoplication was performed in four patients. Three of these patients were diagnosed with a postoperative hiatal hernia. However, the wrap was intact in all three of them. One patient had a laryngotracheoesophageal cleft anomaly and underwent redo surgery. One patient died in the early postoperative period owing to nonsurgical reasons. Seventeen patients died due to nonsurgical reasons.
Conclusion: The indications and postoperative results of ARS in children with cerebral palsy are controversial. According to our results, the main indication for ARS was recurrent aspiration pneumonia, which decreased dramatically in the postoperative period. Long-term results suggest that 58.3% of our patients did not have any complaints and benefited from surgical treatment. Antireflux surgery is an effective and safe treatment for GERD in children with neurological deficits.

Fixed-point theory (FPT) has lot of applications not only in the field of mathematics but also in various other disciplines. Fixed Point Theorem presents that if T:X \(\to\) X is a contraction mapping on a complete metric space (X, d) then there exists a unique fixed point in X. FPT is also essential in game theory, in this case Brower Fixed Point has an application in game theory specifically in non-cooperative games and existence of Equilibrium. In particular, a game is a set of actions done by the participants defined by a set of rules. This is commonly described using mathematical concepts, which offers a concrete model to describe a variety of situations. On the other hand, the separation axioms Ti, i = 0,1,2,3,4 are vital properties that describes the topological spaces T0,T1,T2,T3 and T4. It is noted that a T3 - space is a generalized version of T2- space and since various results on application of fixed point theory in game theory on an arbitrary locally convex T2 - space has been established, in this study we sort to extend this concept to the general T3 - space. The utilization of a symmetric property of Hausdorff space established that if two continuous commutative mappings are defined on a T3 - space, then the two maps achieves unique fixed points.

Sustaining environmental health and sustainable agriculture depend on maintaining the health of the soil. Soil health management is a critical aspect of sustainable agriculture, aiming to maintain and enhance the productivity of soil while minimizing environmental impacts. This bibliometric analysis investigates the evolution and trends in extension approaches for soil health management over the past two decades. Using data from major scientific databases, we analyzed publications on soil health management, focusing on extension methodologies, stakeholder engagement, and the dissemination of best practices. The study identifies key themes, influential authors, prominent journals, and geographical distribution of research activities. The research landscape of soil health management and extension strategies is examined in this bibliometric study. We examine articles that were obtained from such as Scopus, between 2010 and 2023 Publication trends, authorship patterns, keyword co-occurrence networks, and citation analysis are the main areas of our investigation. How effective are different extension approaches in enhancing soil health management practices among farmers?" This Review is to pinpoint important figures in the field, recurring themes in the study, and new lines of investigation. We also investigate how well extension strategies work to spread information and methods for managing soil health. Researchers, decision-makers, and extension staff will benefit greatly from the findings, which will shape future research paths and improve the creation and use of efficient soil health management plans. The problem statement identifies a gap in understanding which extension methodologies most effectively promote soil health, particularly in diverse agricultural settings. Through a comprehensive biometrics analysis, this research evaluates the impact of educational programs, technological interventions, and participatory approaches on soil health indicators such as nutrient levels, soil structure, and microbial activity. Data was collected from a diverse sample of farming communities, and statistical tools were used to analyze changes in soil health parameters over time. The findings are expected to provide insights into optimizing extension strategies for better soil management, thereby contributing to improved agricultural sustainability and resilience.

The experiment was laid in randomized block design (RBD) with three replications consisting of twelve treatments. The treatments included viz. T0: Control, T1: FeSO4 (0.5%), T2: ZnSO4 (0.5%), T3: Borax (0.2%), T4: Ammonium Molybdate (0.03%), T5: FeSO4 (0.5%) + ZnSO4 (0.5%), T6: FeSO4 (0.5%) + Borax (0.2%), T7: FeSO4 (0.5%) + Ammonium Molybdate (0.03%), T8: ZnSO4 (0.5%) + Borax (0.2%), T9: ZnSO4 (0.5%) + Ammonium Molybdate (0.03%), T10: Borax (0.2%) + Ammonium Molybdate (0.03%) and T11: FeSO4 (0.5%) + ZnSO4 (0.5%) + Borax (0.2%) + Ammonium Molybdate (0.03%). Foliar spray of micronutrients was done at 30 and 45 DAT of cauliflower. The results revealed that foliar application of treatment T11 recorded significantly maximum yield parameters such as curd diameter (13.22 cm), curd depth (9.26 cm), curd size index (122.66 cm2), total biomass production per plant (599.73 g), marketable curd weight (315.51 g), net curd weight (208.55g), yield per plot (6.94 kg plot-1) and yield per hectare (231.37 qha-1). In economics T11 incurred maximum total cost of cultivation (Rs. 263739.00 ha-1), gross income (Rs. 809800.44 ha-1), net income ( Rs. 546061.44 ha-1) and maximum benefit: cost ratio 3.07. In contrast, the minimum value for the above parameters were recorded under T1 (control).
Detection of Bulky Endogenous Oxidative DNA Lesions Derived from 8,5′‐Cyclo‐2′‐deoxyadenosine by 32P‐Postlabeling Assay
Authors: Zhou Guo‐Dong , Moorthy Bhagavatula 
Published: May 2015

Abstract8,5′‐Cyclopurine‐2′‐deoxynucleotides represent a class of oxidative DNA lesions that are specifically repaired by nucleotide excision repair but not by base excision repair or direct enzymatic reversion. The 32P‐postlabeling assay is an ultrasensitive method that has been extensively used for the detection of carcinogen‐DNA adducts in laboratory animal and epidemiological studies. This assay under modified chromatographic conditions is also a suitable and sensitive method for the detection of 8,5′‐cyclo‐2′‐deoxyadenosine (cA). After enzymatic digestion of DNA, and enrichment of the oxidative products from the DNA digest, four dinucleotides containing cA, i.e., Ap‐cAp, Cp‐cAp, Gp‐cAp, and Tp‐cAp, are 5′‐labeled with [32P]orthophosphate from [γ‐32P]ATP, mediated by polynucleotide kinase (PNK). The 32P‐labeled cA products are separated by two‐dimensional thin‐layer chromatography (TLC) and quantified by Instant Imager or by a scintillation counter. The assay only requires 1 to 10 μg of DNA sample and is capable of detecting cA lesions at frequencies as low as 1 in 1010 normal nucleotides. © 2015 by John Wiley & Sons, Inc.
Thin current sheet formation in response to the loading and the depletion of magnetic flux during the substorm growth phase
Authors: Hsieh M.‐S. , Otto A. 
Published: May 2015

AbstractThe physics of geomagnetic substorms has been under debate for a long time. Although the growth phase has received less attention than the spectacular expansion phase, the state of the magnetotail at the end of the growth phase, i.e., a thin current sheet (CS) formation is of central importance because it provides the magnetotail conditions for the expansion phase onset. This study investigates CSs evolution during the substorm growth phase. The growth phase physics considered here includes the removal of closed magnetic flux in the near‐Earth tail and the addition of magnetic flux into the tail lobes. It is found that two separate CSs evolve at distinct locations in the near‐Earth and the midtail region in response to the depletion and the loading of magnetic flux. The relative current densities in the dual‐current‐sheet configuration depends strongly on whether the depleted or the added magnetic flux dominates. The presented results suggest that substorm expansion onset may be associated only with reconnection onset in the near‐Earth CS, while midtail reconnection causes bursty bulk flows or bubbles.
Realistic simulations of atmospheric gravity waves over the continental U.S. using precipitation radar data
Authors: Stephan Claudia , Alexander M. Joan 
Published: May 2015

AbstractConvectively forced gravity waves can affect the dynamics of the upper troposphere and middle atmosphere on local to global scales. Simulating these waves requires cloud‐resolving models, which are computationally expensive and therefore limited to case studies. Furthermore, full‐physics models cannot accurately reproduce the locations, timing, and intensity of individual convective rain cells, limiting the validation of simulated waves. Here, we present a new modeling approach that retains the spatial scope of larger‐scale models but permits direct validation of the modeled waves with individual cases of observed waves. Full‐physics cloud‐resolving model simulations are used to develop an algorithm for converting instantaneous radar precipitation rates over the U.S. into a high‐resolution latent heating/cooling field. This heating field is used to force an idealized dry version of the WRF model. Wave patterns and amplitudes observed in individual satellite overpasses are reproduced with remarkable quantitative agreement. The relative simplicity of the new model permits longer simulations with much larger and deeper domains needed to simulate wave horizontal/vertical propagation. Eliminating the complicating factors of cloud physics and radiation this approach provides a link between conceptual and full‐physics models and is suitable for studying wave‐driven far‐field circulation patterns.
Implications of RCP emissions for future changes in vegetative exposure to ozone in the western U.S.

Published: May 2015

AbstractFuture changes in anthropogenic emissions of ozone precursors will likely impact seasonal vegetative ozone exposure, W126, in the western U.S. To investigate this, source‐receptor relationships are calculated with the GEOS‐Chem adjoint model and are separated by location, species, and sector. These are used to project changes in W126 through midcentury following representative concentration pathway (RCP) emissions. The overall behavior of W126 is governed by declining domestic emissions. However, foreign emissions of NOx, non‐methane volatile organic compounds, and CO and CH4 abundance can either slow or enhance this trend, depending on scenario. The relative importance of foreign emissions increases as U.S. emissions decline, and, in some cases, the contribution of foreign sources exceeds that of domestic as early as 2020. In 2050, W126 in the western U.S. contributed by Chinese emissions alone, dominated by the industrial sector, is up to 15% higher than in 2000, although such estimates are strongly dependent on scenario.
Modulation of Antarctic vortex composition by the quasi‐biennial oscillation
Authors: Strahan S. E. , Oman L. D. , Douglass A. R. , Coy L. 
Published: May 2015

AbstractUsing a decade of Aura Microwave Limb Sounder observations, we show distinctly different N2O distributions in Southern Hemisphere winter that depend on the phase of the quasi‐biennial oscillation (QBO). Composites of the nitrous oxide (N2O) anomalies calculated for westerly and easterly phases show that QBO‐generated variability originating in the subtropical middle stratosphere fills the midlatitude surf zone by late winter. After the spring vortex breakup, the anomaly is transported to the Antarctic where it remains until the next vortex forms in fall. Trapped in the newly formed vortex, the anomaly descends in isolation through fall and winter, arriving in the Antarctic lower stratosphere in September—about 1 year after it formed. This transport pathway explains previously reported variability of N2O and inorganic chlorine (Cly) inside the Antarctic vortex and demonstrates that the middle stratosphere QBO affects ozone depletion by modulating Antarctic Cly.
