Post-Return Stroke VHF Electromagnetic Activity in North-Western Mediterranean Cloud-to-Ground Lightning Flashes
Authors: Kolínská Andrea , Kolmašová Ivana , Defer Eric , Santolík Ondřej , Pédeboy Stéphane
Published: September 2024

Abstract. We investigate properties of the electromagnetic activity following the first lightning return stroke (RS), using concurrent observations from the SLAVIA (Shielded Loop Antenna with a Versatile Integrated Amplifier) sensor, the lightning mapping array (LMA) SAETTA (Suivi de l'Activité Electrique Tridimensionnelle Totale de l'Atmosphère) and Météorage LF network in the Corsica region. From the data collected between September and December 2015, we selected 66 negative cloud-to-ground (-CG) and 26 positive cloud-to-ground (+CG) lightning flashes in the north-western Mediterranean region. In the SAETTA data, we observe a decrease of the Very High Frequency (VHF) radiation rate and the VHF power as recorded within a typical 80-µs time window at the LMA stations, immediately after the RS pulse in 59 -CG flashes. Contrastingly, we show that all examined +CG flashes exhibit a rapid increase of the VHF radiation rate and the VHF power immediately after the RS. We suggest a possible explanation of this phenomenon by considering step-like propagation of a negative part of bidirectional leader starting at the top end of the positive lightning channel inside the thundercloud, emitting electromagnetic radiation across a broad frequency spectrum.
Subglacial and subaerial fluvial sediment transport capacity respond differently to water discharge variations
Authors: Delaney Ian , Tedstone Andrew , Werder Mauro A. , Farinotti Daniel
Published: September 2024

Abstract. Sediment transport capacity in both subaerial and subglacial channels depends on the shear stress exerted across the channel bottom, which varies with water velocity and channel width. In subaerial channels, water discharge variations are accommodated by flow depth and width changes, along with water velocity. However, in subglacial channels, water is pressurized by the ice above, and they grow in response to frictional heating of water flowing through them. As a result, water discharge changes mainly result in velocity variations, as the channel geometry evolves slowly (over days). Here, we present formulations of sediment transport capacity in different channel types and apply subglacial and subaerial hydraulics models to hydrographs from an Alpine glacier and the Greenland Ice. Numerical experiments show that the changing channel size results in sediment transport capacity peaking before the maximum water discharge. This hysteresis in channel size causes a highly variable relationship between sediment and water discharge in a transport-limited subglacial system. The results also indicate that high subglacial sediment transport capacities can occur across a wide range of water discharges. A second set of numerical experiments shows that subglacial sediment transport is highly non-linear with respect to water discharge, creating more variability in sediment transport capacity. Yet, results and formulations of subglacial sediment transport capacity show that its variability can approach that of subaerial systems when subglacial channel size is in equilibrium with water discharge. The implications of these findings are discussed in the context of sediment discharge from glaciers with different hydro-climatic forcings. We also discuss the impact of different assumptions of channel behavior on sediment transport capacity. These findings can improve the interpretation of sediment discharge records in glacierized catchments.
Increased sensitivity in Electron Nuclear Double Resonance spectroscopy with chirped radiofrequency pulses
Authors: Stropp Julian , Wili Nino , Nielsen Niels Christian , Klose Daniel
Published: September 2024

Abstract. Electron Nuclear Double Resonance (ENDOR) spectroscopy is an EPR technique to detect the nuclear frequency spectra of hyperfine coupled nuclei close to paramagnetic centres, which have interactions that are not resolved in continuous wave EPR spectra and may be fast relaxing on the time scale of NMR. For the common case of non-crystalline solids, such as powders or frozen solutions of transition metal complexes, the anisotropy of the hyperfine and nuclear quadrupole interactions renders ENDOR lines often several MHz broad, thus diminishing intensity. With commonly used ENDOR pulse sequences only a small fraction of the NMR/ENDOR line is excited with a typical RF pulse length of several tens of μs, and this limits the sensitivity in conventional ENDOR experiments. In this work, we show the benefit of chirped RF excitation in frequency domain ENDOR as a simple yet effective way to significantly improve sensitivity. We demonstrate on a frozen solution of Cu(II)-tetraphenylporphyrin that the intensity of broad copper and nitrogen ENDOR lines increases up to 9-fold compared to single frequency RF excitation, thus making the detection of metal ENDOR spectra more feasible. The tunable bandwidth of the chirp RF pulses allows the operator to optimize for sensitivity and choose a tradeoff with resolution, opening up options previously inaccessible in ENDOR spectroscopy. Also, chirp pulses help to reduce RF amplifier overtones, since lower RF powers suffice to achieve intensities matching conventional ENDOR. In 2D TRIPLE experiments the signal increase exceeds 10 times for some lines, thus making chirped 2D TRIPLE experiments feasible even for broad peaks in manageable acquisition times.

Abstract. Gully erosion can be combatted in severely affected regions like sub-Saharan Africa using various low-cost interventions that are accessible to affected farmers. For successful implementation, however, biophysical evidence of intervention effectiveness needs to be validated against the interests and priorities of local communities. Working with farmers in a watershed in southern Ethiopia, we investigated (a) the effectiveness of low-cost gully rehabilitation measures to reduce soil loss and upward expansion of gully heads; (b) how farmers and communities view gully interventions; and (c) whether involving farmers in on-farm field trials to demonstrate gully interventions improves uptake, knowledge, and perceptions of their capacity to act. On-farm field experiments, key-informant interviews, focus group discussions, and household surveys were used to collect and analyse data. Three gully treatments were explored, all with riprap, one with grass planting, and one with grass planting and check-dam integration. Over a period of 26 months, these low-cost practices ceased measurable gully head expansion, whereas untreated gullies had a mean upward expansion of 671 cm, resulting in a calculated soil loss of 11.0 t. Farmers had a positive view of all gully rehabilitation measures explored. Ongoing rehabilitation activities and on-farm trials influenced the knowledge and understanding of similar gully treatments among survey respondents. On-farm experiments and field day demonstrations empowered farmers to act, addressing pessimism from some respondents about their capacity to do so.

Advance in age outcomes changes that disrupts the function of the salivary glands which are weakened vigorously. Advanced worsening in the histological structure of submandibular gland alters production of saliva. This study was hypothesized to point out the micro-cellular variations with aging in submandibular salivary glands, moreover to detect the role of myoepithelial markers and the propensity of malignant transformation with aging. Fifty male rats were used: group I (young adult), group II (senile). Light microscopic techniques (H&E, Masson trichrome, immunohistochemistry for vimentin, cytokeratin and PCNA) and electron microscopy were used. MDA, GSH and SOD, and a molecular study for p53 was evaluated. The submandibular gland of old rats shows variable sized, shrunken acini, and necrosis. Swollen intercalated ducts with eccentric lumina, and irregular striated ducts are reported. E.M. revealed degenerated myoepithelial cells, cytoplasmic rarefaction, marked reduction of the nuclear chromatin, large macrophages with large lysosomes and many endocytic vesicles. The mean area percent of collagen fibers, vimentin, and cytokeratin in senile rats exposed significant increase and a significant decrease of mean number of PCNA cells when compared to young rats. The mean values of MDA, P53 revealed a significant surge, while that of GSH and SOD exhibited a significant decline when compared to adult rats. Vimentin and cytokeratin have a direct correlation with aging in the submandibular gland. They are concomitant with hyperplastic changes in the gland so they might be a strong indicator of presence of a tumor.

Accurate age estimation holds paramount importance across various fields, encompassing forensic sciences, civil law, and the medicolegal domain. The applicability of the staging and atlas method for calculating dental age in Indonesian children and adolescents was assessed for this purpose. This study encompassed 104 orthopantomographs from outpatients (54 males and 50 females, aged 5-18 years) at the Airlangga University Dental Hospital in Surabaya, Indonesia. An analysis was conducted to determine the significance of the difference and the correlation between chronological age (CA) and estimated dental age (EDA). The findings unveiled a robust correlation between CA and EDA, with correlation coefficients surpassing 0.9 for both approaches. Although the London Atlas method exhibited a marginally lower Mean Absolute Error (MAE) of 0.81 years in comparison to the Nolla method’s MAE of 0.88 years, the difference between the two was deemed insignificant. The outcomes of this study provide valuable insights into the utility of the Nolla and London Atlas methods for estimating dental age among Indonesian youth. However, it is imperative to note that further investigations are warranted to validate these findings and to ascertain the generalizability of these methods across diverse populations.

The liver remains the target organ for the accumulation of cadmium toxicity, mediated by the upregulation of reactive oxygen species. Allium cepa constitutes a potential source of natural antioxidants, while Ivermectin has been identified to treat a range of diseases, having antimicrobial, antiviral, and anti-cancer properties. Therefore, this study investigated the protective effects of Ivermectin and Allium cepa on cadmium-induced liver damage in adult Wistar rats. Twenty-eight (28) adult female Wistar rats were randomly divided into six (6) groups. Group A, control received distilled water; Group B, treated with 1.2 mg/kg b.w of Ivermectin; Group C, treated with 1.2 mg/kg b.w of Ivermectin and 2 mg/kg b.w Cadmium respectively; Group D, treated with 2 mg/kg b.w cadmium; Group E, treated with 2 mg/kg b.w Cadmium and 1.5 ml Allium cepa respectively; and Group F, treated with 1.5 ml Allium cepa. Single dose administration of cadmium was done intraperitoneally, while administration of Ivermectin and Allium cepa were given orogastrically for four (4) weeks. Animals were sacrificed twenty-four (24) hours after the last administration, and the right lobe of liver was excised following the abdominal incision, and then fixed in Bouin’s fluid for histological observation, while the left lobe of the liver was homogenated in 5% sucrose solution for biochemical assay using LDH, MDA, SOD and Catalase enzyme activity. Cadmium administration caused elevation of MDA enzyme activity, promoting cell membrane lipid peroxidation following cellular non-traumatic injury, similarly significantly increased LDH and Catalase activity, while it reduced the SOD enzyme activity. Histopathological changes associated with cadmium showed vacuolar and granular degenerations in hepatocytes, heterochromatic nucleuses and sinusoidal, hepatic deposits of amyloidal plaques. However, Ivermectin and Allium cepa treatment maintained the biochemical parameter integrity and the histological features relative to the control animals. Administration of Allium cepa and Ivermectin preserved liver histoarchitecture and maintained biochemical integrity of antioxidants and carbohydrate metabolic enzyme. More importantly, the antioxidant properties of the Allium cepa and the therapeutic action of Ivermectin had proved efficient against cadmium-induced liver damage in adult Wistar rats.

Published: September 2024

This study identifies the endogenous and exogenous factors that influence whether small coffee-growing households decide to join agricultural cooperatives in South Kivu, a conflict-prone province in the eastern Democratic Republic of Congo (DRC).
After a pilot test, data were collected through a cross-sectional survey in the territories of Kabare, Kalehe and Idjwi, and 412 randomly selected small coffee producers, coffee cooperative members and non-members participated in the survey. Geographical representativeness was observed in the distribution of this sample across the three territories. A logit model was applied to determine the main factors of membership.
In a challenging context such as the eastern DRC, trust in the leaders and initiators of an agricultural cooperative, the need for small coffee-growing households to build up social capital through the cooperative and the household’s perception of the adequacy of the economic benefits (dividends) to be received were the most significant factors in the decision to join or remain in an agricultural cooperative. Other factors such as the age of the household head, the household’s need to access to agricultural inputs and technical training, and the distance between the plantation and the nearest coffee washing station also had a significant effect on the decision to join a coffee cooperative in the eastern DRC. The results of this study help to clarify the dynamics of rural development and the management of agricultural cooperatives in difficult socioeconomic contexts, such as the eastern DRC. The findings also have implications for actions, strategies and public policies to be adopted by cooperatives, market system development actors and the government to promote social cohesion and improve the living conditions of the rural population through agricultural cooperatives.

Georgia is a small country, therefore, the effective use of the special possibilities of natural and climatic conditions for growing local or introduced plants is especially important for the country. Today, unfortunately, in many cases, the soil is not used properly. It is cultivated with plants that are not studied or not suitable for environmental conditions. Crop production (leaf, fruit, etc.) is cost-effective when studying its chemical composition using modern physicochemical methods. The research is particularly relevant when it comes to plants containing biologically active compounds. Therefore, there’ should be established qualitative and quantitative content, as well as the chemical structure and biological activity of a plant. There’ should also be studied the optimal period of accumulation of these compounds and, accordingly, the harvest time of raw material. It is important to adapt the most optimal (chemical composition, yield and other) varieties in this region. It is necessary to develop processing technology and pay attention to monitoring of biologically active compounds during the processing and in the obtained product. Early studies have shown that the Stevia plant of South American origin is particularly effective for soil and climatic conditions of western Georgia.

Published: September 2024

Numerous disciplines have been changed by nanotechnology, which is the manipulation of matter at the atomic and molecular size. The possibility that nanotechnology may be a catalyst for political change is discussed in this research. We study how the uses of nanotechnology might affect power relations, democratic processes, and international order by looking at the nexus between technology, society, and governance. Here discussed how nanotechnology might improve or subvert current political systems. Investigating its potential to address global issues including energy security, healthcare inequities, and climate change is part of this. We also explore the ethical ramifications of nanotechnology, covering security, equality, and accessibility concerns. The study makes the case that although nanotechnology has a lot of potential to benefit society, its effects on politics will be nuanced and varied. To guarantee that nanotechnology is created and applied in a way that advances human welfare and democratic principles, it is imperative to consider both the possible advantages and hazards. Through the promotion of critical discourse and responsible governance, the revolutionary potential of nanotechnology may be used for the benefit of society. In the end, this study hopes to spark debate on the complex link between politics and nanotechnology and to motivate academics, politicians, and the general public to participate in determining the direction of this potent technology.

Published: September 2024

Introduction. Despite extensive studies devoted to comprehensive comparisons of the expression of mRNA, proteins, mutations in cell cultures and tissue samples of breast cancer, there is insufficient data on the comparability of their receptor apparatus.

The purpose of the study was to determine changes in receptor expression levels in a cell culture obtained from a sample of the luminal B over five passages.

Materials and methods. A cell culture was obtained. Estrogen and Ki‑67, pancytokeratin and vimentin were analyzed over five passages. Paraffin blocks were prepared from part of the material for immunohistochemical analysis.

Results and discussion. A culture was obtained with high levels of Ki‑67 and estrogen expression during the first three passages. The cells maintained their epithelial nature throughout the culture. Perhaps this culture can demonstrate the processes occurring during regional metastasis. This is evidenced by the detection of tumor cells expressing vimentin from the first to the fourth passage. Thus, studying the processes occurring in in vitro models will help to come closer to understanding the processes in the biology of breast cancer and clarify the nature of the heterogeneity of this disease.

Conclusions. Studying the differences between primary culture cells and tumor tissue samples will provide an effective in vitro model.

Hybrid Recommender System Using CNNs, Bi-Directional RNNs, and Autoencoders
Authors: Naveen Kumar Navuri
Published: September 2024

This research presents an innovative hybrid recommender system that utilizes stacked Convolutional Neural Networks (CNNs), Bi-Directional Recurrent Neural Networks (RNNs), and Improved Autoencoders to deliver highly accurate and tailored product recommendations. Conventional recommendation methods including collaborative and content-based filtering, frequently struggle to accurately capture the complex and ever-changing connections between users and objects. In order to address these constraints, our hybrid approach integrates multiple deep learning methodologies to extract and merge visual, temporal, and latent characteristics from user interaction and product data.
The proposed method begins by employing convolutional neural networks (CNN) with layered architectures to extract visually rich and high-quality features from product photos. Afterwards, these visual characteristics are merged with embedded metadata via attention mechanisms, thus guaranteeing the precise acquisition of important visual and contextual data. Subsequently, bi-directional recurrent neural networks (Bi-RNN) are used to capture the temporal patterns of user activities, so providing a thorough comprehension of user behavior over a prolonged duration. Ultimately, the temporal features are combined with the visual features to offer a unified and complete user preferences representation, leading to a strong and well-balanced representation.
To boost the accuracy of suggestions, the combined features undergo processing using an advanced autoencoder that integrates residual blocks and attention processes. This autoencoder utilizes dimensionality reduction and reconstruction techniques to enhance the features and eliminate noise. The resulting brief and informative representations of features are subsequently employed to create suggestions.
The validation of our model is conducted using the TMDB dataset, which includes comprehensive metadata, textual descriptions, and visual content for movies. The findings of our experiment demonstrate significant enhancements in both the accuracy and relevance of recommendations when compared to conventional methods and other deep learning-based approaches. Specifically, our approach showcases improved efficiency in collecting complex user-item interactions and adjusting to evolving user preferences over time. This hybrid methodology provides a resilient solution for contemporary recommender systems, resulting in enhanced and tailored user interactions.

Authors: Venkata Prasanna N
Published: September 2024

This study uses Icosagonal Fuzzy Numbers (IFNs) to assess the quality of healthcare services in Andhra Pradesh across four zones, we rank characteristics such as appointment scheduling, medical quality, hygiene, lab efficiency, care quality, safety, value for money, dependability, cost-effectiveness, facility quality, and recommendations. Data analysis suggests that hygiene is the most important factor in both zones. A comparison with other fuzzy number approaches (Pentagonal, Hexagonal, Heptagonal, and Hex-Decagonal) reveals that IFNs provide a more nuanced view of service quality. The findings provide insights for enhancing healthcare services in Andhra Pradesh.
Ranking Fuzzy Numbers by Defuzzification using Volumes
Authors: P. N. V. L. Sasikala
Published: September 2024

Fuzzy numbers (FNs) are used to represent uncertain and ambiguous data and are mainly useful in decision-making. Ranking fuzzy numbers is an important concept in fuzzy set theory and has various applications in decision-making, data analysis, artificial intelligence, and optimization problems. To overcome the shortcomings in some of the existing fuzzy ranking methods, in this paper, we introduce a new ranking method for ranking generalized trapezoidal fuzzy numbers (GTrFNs) by a defuzzification technique using a score function defined using the volume of the solid obtained by revolving the left and right inverse membership functions of GTrFN about a vertical line. This score represents the defuzzified value of the GTrFN and is used to rank FNs. The proposed ranking method can rank different types of FNs in an effective manner and can be implemented in real-time applications like multicriteria decision-making and risk analysis.

Authors: Chiranjeevi Perala
Published: September 2024

The aim of this paper is to establish three common fixed point theorems in Multiplicative Metric Space (MMS). By utilizing the conditions concepts of non-continuous and non-compatible mappings.The first theoem is generated by applying the concepts of semi-compatible mapping, WCM and reciprocally continuous mappings.The second theorem is established by using the concepts of strongly semi compatible mappings,conditionally reciprocally continuous mappings and and OWC mappings. These conditions  are weaker than the existing conditions like compatible mappings and cotinuous which generalizes the theorem of Afrah A. N. Abdou.
Menger Space and Some Contraction Mappings
Authors: Ajay Kumar Chaudhary
Published: September 2024

Menger space is a probabilistic metric space introduced by K. Menger [15] in 1942 as one of the generalizations of metric space. The two different types of contraction mappings in probabilistic metric spaces are the creation of V.M. Sehgal [20-21], and T.L. Hicks [14]. Since then many researchers have introduced generalizations of these contraction mappings and established fixed point theorems in Menger space. 
In this paper, we discuss Menger space and contraction mapping in Menger space. Also, presents the interrelationship between some contraction mapping with examples.
A Mathematical Approach for Stability Analysis of MHD Nanofluid Flow and Heat Transfer over a Stretching Sheet with Thermal Dispersion and Variable Viscosity
Authors: Vinodkumar
Published: September 2024

Incorporating thermal dispersion and variable viscosity effects, the stability analysis of magnetohydrodynamic (MHD) nanofluid flow and heat transfer over a stretching sheet is performed in this article on the basis of comprehensive mathematical framework. This study deals with important features of MHD nanofluid dynamics, stressing the effect of viscosity variation on the stability and flow attributes. Governing equations including both momentum and thermal energy transfer are developed, then non-dimensionalized to expose the important dimensionless numbers. Linear stability analysis is used to find the critical conditions of flow, under which the flow is seen stable. Heat transfer efficiency is evaluated while accounting for thermal dispersion, and interacting with variations in viscosity. Controlled stability equations solved using eigenvalue analysis and numerical methods yield critical values for several parameters. These findings are crucial with regard to the important influence of thermal dispersion and variable viscosity in improving its stability for several practical industrial devices like cooling systems, energy storage units as well as types of manufacturing industries involving advanced technologies. This research has extended the understanding of the stability analysis for low-Prandtl-number MHD nanofluid flows, which could be helpful to develop ways by means of simpler and effective controlling when designing heat transfer devices.

Authors: Aparna Jagtap
Published: September 2024

Self-compacting concrete has improved quality and improved performance and performance due to its high capacity and elimination of collisions. Self-compacting concrete is designed for structures with complex reinforcement and without vibration. Does a good job of covering the ground.Fiber contribution in self-compacting concrete is 1.2%, 1.8% and 2.2%. In cases where fly ash remained unchanged, comparative studies were conducted on the compressive strength of self-compacting concrete with different polypropylene fiber contents. 25% fly ash is also used instead of cement. Extensive benefits of self-compacting concrete (SCC) in full fill the mold and achieving full compaction without vibration, with good behavior after concrete cracking, raise the idea of self-compacting concrete production. The fundamental challenge in this area is the unsatisfactory performance of concrete with fibers; In other words, using fibers in concrete will reduce concrete fluidity. In this research paper polypropelenfiber is used to improve the compressive strength of self compacting concrete.
