Authors:   Department of Saidla, Faculty of Unani Medicine, Aligarh Muslim University, Aligarh UP, India, Rahman Aziz	ur
Published: February 2025

Back ground and objective: The study was envisaged to design and develop a poly herbal shampoo along with its microbial analysis and standardization. In this study some Unani potent antidandruff drugs have been selected for preparation of shampoo. These herbs have antifungal, antimicrobial, radio protective, ant oxidative, anti-greying, anti-lice properties mentioned in classical literature as well as substantiated by recent studies. These herbs also promote healthy hair growth and exhibit soothing effects on scalp and hairs.

Material and method: Three different batches (F1, F2, and F3) of the shampoo were prepared by using aqueous extract of medicinal herbs. Among these batches, on the basis of the results of post formulation studies batch F1 was found most suitable and subjected for further evaluation. For quality assurance, physico-chemical tests i.e. pH, determination of solid residue, wetting time of shampoo, detergency evaluation, surface tension, viscosity, foam volume and stability, dirt dispersion, thermal and mechanical stability were carried out. Further, the optimized batch of the shampoo was also evaluated for its antimicrobial activity especially against fungus Malassezia furfur and accelerated stability studies.

Observation and result: The findings of physico-chemical studies and quality parameters of selected batch F1 were in accordance with the prescribed limits. The shampoo exhibited significant antimicrobial activity against different gram positive and gram negative bacterial strains. More over it also demonstrated antifungal activity against Malassezia furfur, which is one of the main causative organisms for producing scalp dandruff. Further, no significant changes were observed in physico-chemical properties of tested shampoo during the accelerated stability studies and the shelf life was predicted as at least of 02 years.

Authors: Muryani Luluk , Sugiyanto Sugiyanto
Published: February 2025

Poverty and income inequality in the community are strategic issues for the Yogyakarta City Government. One of the reasons is the low competitiveness of small businesses and the lack of strong synergy between poverty alleviation programs and activities. This encouraged the initiation of the Gandeng Gendong program innovation, namely a collaboration program between development stakeholders. To realize Gandeng Gendong's innovation, it is necessary to strengthen the role of stakeholders, namely cities, corporations, campuses, communities and villages, which is acronymed with the term 5K. Strong stakeholders will have a positive impact on the success of the tandem carrying program. Qualitative descriptive research approach. Informants were selected according to purposive sampling technique. Data collection techniques using interview, observation and documentation methods. Primary and secondary data are integrated into content analysis and then tested using triangulation techniques.  The research results show that the collaboration program has had a positive impact in reducing poverty rates. From 2019 to 2023, the poverty rate experienced a downward trend, namely 0.86%. Apart from that, the level of participation of people who are members of the gangen gendong program, especially in the nlarisi application, is increasing. However, several obstacles were still found, namely that assistance from authorized Regional Apparatus Organizations was felt to be insufficient.

Detection of Multi-Modal Doppler Spectra. Part 2: Evaluation of the Detection Algorithm and Exploring Characteristics of Multi-modal Spectra Using a Long-term Dataset
Authors: Wugofski Sarah , Kumjian Matthew R.
Published: February 2025

Abstract. In this paper, we process three years of vertically pointing Ka-band radar spectral data according to the methodology described and established in Part 1 (Wugofski et al. 2025). Across three years of data, we demonstrate the detection algorithm is successful in identifying multi-modal spectra, with 90.8 % of detected events verifying. Beyond the verification, we explore other characteristics of the detected events such as the height, depth, and temperature of the layers containing secondary modes. Reanalysis data from ERA-5 was used to gain additional context to the environmental conditions associated with the detected events. By connecting temperatures from ERA-5 with the detected layers, we access the potential for these events to be associated with common microphysical processes such as growth of columns or plates, Hallett-Mossop rime splintering, dendritic growth, and primary ice nucleation. We further explore the potential microphysical processes revealed by the multi-modal spectra using linear depolarization ratio to determine if the secondary mode may comprise ice crystals that can produce such a signal. Of the cases with a detected enhanced LDR signal, >55 % of those occurred in a layer with a mean temperature consistent with Hallett-Mossop rime splintering. Finally, three cases are investigated in more detail to illustrate the variety of events detected by the algorithm.

Abstract. The continuous uptake of anthropogenic CO2 by the ocean leads to ocean acidification, which is an ongoing threat to marine ecosystem. The ocean acidification rate has been globally documented in the surface ocean, but this information is limited below the surface. Here, we present a monthly 4D 1°×1° gridded product of global seawater pH on the total scale and at in situ temperature (without standardization to 25 °C), derived from a machine learning algorithm trained on pH observations from the Global Ocean Data Analysis Project (GLODAP). The proposed pH product covers the years from 1992 to 2020 and depths from the surface to 2 km on 41 levels. A three-step machine-learning-based algorithm was used to construct the pH product, incorporating region division via a self-organizing map neural network, predictor selection via the stepwise regression algorithm that adds and removes variables from network inputs based on their contribution to reducing reconstruction errors, and nonlinear relationship regression by feedforward neural networks (FFNNs). The performance of the machine learning algorithm was validated using real observations with a cross-validation method, in which four repeating iterations were carried out with each iteration utilizing a different 25 % subset of observations for validation and the complementary 75 % subset for training. The proposed pH product is evaluated using comparisons to time-series observations and the GLODAP pH climatology. The overall root-mean-square error between the FFNN-reconstructed pH and the GLODAP measurements is 0.028, ranging from 0.044 at the surface to 0.013 at 2000 m. The pH product is distributed via the Marine Science Data Center of the Chinese Academy of Sciences: https://doi.org/10.12157/IOCAS.20230720.001 (Zhong et al., 2023).

Abstract. Reversed eutrophication, called oligotrophication, has widely been documented globally over the last 30 years in rivers, lakes, and estuaries. However, the absence of a comprehensive and harmonized dataset has hindered a deeper understanding of its ecological consequences. To address this data gap, we developed the OLIGOTREND database, which contains multi-decadal timeseries of chlorophyll-a, nutrients (nitrogen and phosphorus), and related physicochemical parameters, totalling 4.3 million observations. These data originate from 1,894 unique monitoring sites, mainly located in high-income countries, and across estuaries (n = 238), lakes (687), and rivers (969). Each location is associated to catchment and hydroclimatic attributes. Trend and breakpoint analyses were applied to all timeseries. Chlorophyll-a showed temporally variable and ecosystem-specific responses to nutrient declines with an overall declining trend for 18 % of the time series, contrasting greatly with a majority of declining trends for nutrient concentrations. We harmonized the database to ensure reproducibility, ease of access, and support future updates and contributions. Available at https://doi.org/10.6073/pasta/a7ad060a4dbc4e7dfcb763a794506524 (Minaudo & Benito, 2024) the OLIGOTREND database supports collaborative efforts aimed at further advancing our understanding of biogeochemical and biological mechanisms underlining oligotrophication, and ecological impacts of global long-term environmental change.

Published: February 2025

This article aims to provide a concise yet comprehensive overview of the etching
works created by various artists of the Armenian diaspora during the 1930s–1980s.
These works were produced under challenging historical and socio-political
circumstances in different countries around the world.
The article examines the available etchings of famous French-Armenian artists
Garzu, Zhansem, as well as Egyptian-Armenian Onnik Avetisyan, Italian-Armenian
Zhirayr Oragyan, who are known to the narrower circles of the art-loving public, and
through genre-thematic analyzes of individual works, the features of the artist’s work in a
given cultural environment and the connection with the aesthetic achievements of that
time are shown.
The work is based on studies of artistic, stylistic and etching techniques employed
by Armenian Diaspora artists. As a result of the study, we come to the conclusion that Armenian artists working
abroad were closely related to the cultural ferment taking place in the given country and
were greatly influenced by the Western, to different directions of modernism. Nevertheless,
their art remained deeply intertwined with national issues, as its unique characteristics were closely
connected to their cultural roots and notions of identity.

A multi-frequency ICA-based approach for estimating voxelwise frequency difference patterns in fMRI data
Authors: Behzadfar Neda , Mathalon Daniel , Preda Adrian , Iraji Armin , Calhoun Vince D
Published: February 2025

In resting-state functional magnetic resonance imaging (fMRI) studies, blood oxygenation level dependent (BOLD) signals exhibit temporal correlation across voxels. Prior research has established resting-state functional connectivity (RSFC) across multiple frequency ranges, indicating that functional integration between brain regions occurs at various frequencies. While a few studies have studied RSFC data filtered into different frequency ranges, prior work has focused on extracting the main effects of frequency and comparing them post hoc, rather than focusing on estimating multivariate spatial patterns explicitly capturing frequency differences. Here, we propose a novel multi-stage independent component analysis (ICA)-based approach for estimating frequency difference patterns (FDPs) in fMRI data. Our novel approach involves separating fMRI images into four frequency sub-bands, concatenating them, and then applying group ICA to extract informative components. After removing non-gray matter components (edge effects, white matter, ventricles), we compute voxelwise differences between these sub-bands and perform a second ICA stage. This allows us to identify distinct covarying spatial patterns associated with FDPs. Understanding the frequency-dependent characteristics is crucial for uncovering the underlying spatial and temporal signatures of brain activity across different frequency bands. This method allows for a more comprehensive spatial analysis of frequency-specific filtered fMRI data as it captures the frequency differences within maximally spatially independent spatial maps via a multivariate model. We applied our method to fMRI data from 90 subjects with schizophrenia (SZ) and 90 healthy controls. Our approach revealed structured spatial and temporal patterns which showed frequency-specific partial overlap with known resting-state networks (RSNs) but also exhibited unique spatial patterns. Our frequency-specific analysis unveils connectivity that might be overlooked by single frequency band methods, providing a new window into the brain’s functional architecture. These findings suggest that RSFC is a spatially distributed multi-frequency band phenomenon and highlight the potential for further investigation of BOLD signals in relation to cognitive processes.

En las comunidades de habla hispana hay una serie de instituciones y autoridades académicas que buscan regular el uso correcto de la lengua al ofrecer recomendaciones sobre cómo emplear ciertas expresiones. Sin embargo, en muchas ocasiones hay desacuerdos entre ellas, lo que no permite determinar qué usos deberíamos adoptar. Más aún, no siempre es claro o explícito cuáles son las razones o argumentos detrás de sus recomendaciones. Este libro analiza casos en los que no hay un acuerdo claro entre las autoridades de la lengua y los argumentos para apoyar sus recomendaciones, o bien no son claros o explícitos o simplemente están ausentes. El objetivo del libro, más que ofrecer recomendaciones categóricas para cada caso analizado, es identificar y sacar a la luz los argumentos que pueden guiar nuestras decisiones sobre cómo usar cierta expresión. Se ofrecen evaluaciones críticas de cada uno de los argumentos, de las cuales el lector podrá sacar sus propias conclusiones. Se busca fomentar así una actitud crítica hacia el uso que hacemos de nuestro lenguaje oral y escrito en contextos académicos.

Published: February 2025

El panorama epidemiológico de México es complejo. Enfermedades crónicas, emergentes y reemergentes conforman la casuística de padecimientos que diariamente se atienden en las unidades médicas de nuestro país; a este escenario se deben sumar las lesiones no intencionales que no siempre se les considera dentro de las prioridades de las políticas de salud. Las lesiones no intencionales, también conocidas como accidentes, constituyen un problema actual y urgente de salud pública derivado de la multicausalidad que propicia un ambiente lleno de factores intrínsecos y extrínsecos como, por ejemplo, la casa, la escuela, el lugar de trabajo o el trayecto a estos sitios. Las asfixias, las caídas, los ahogamientos o los eventos producidos en vehículo automotor son algunos ejemplos de motivos de lesiones no intencionales, sobre todo en los menores de diez años. En salud pública, la vigilancia epidemiológica es fundamental para la toma de decisiones, pero ¿se cuenta en México con un sistema apropiado para la vigilancia de las lesiones no intencionales? En este capítulo se desarrollará una breve revisión de las oportunidades de mejora en esta materia.
Niños solos en el hogar (niños de la llave), una cultura o una necesidad
Authors: Sevilla Elizabeth
Published: February 2025

Dejar a los niños solos en el hogar es una práctica global cuando por motivos laborales los padres tienen que acudir al trabajo y no cuentan con el apoyo para dejarlos en algún centro de cuidado infantil. En estos casos se suele delegar el cuidado a los “hermanos mayores”, quienes todavía requieren ser cuidados, y que son en quienes debe recaer la responsabilidad de la seguridad en el hogar. Esto cobra mayor relevancia al ser el hogar el lugar en donde son más frecuentes las lesiones no intencionales en niños. La pobreza, un hogar monoparental, las malas condiciones de trabajo, las insuficientes redes de apoyo y la incapacidad para pagar los servicios de cuidado son algunas razones para dejar a los niños solos en casa. Cuando los hogares son monoparentales hay un 50% más de riesgo de exclusión social y ello conlleva circunstancias en la forma de vida que pueden agravar los riesgos al ser responsables de la crianza de los niños y del sustento económico del hogar que muchas veces no logran conciliarse.
El cuidado sensible y cariñoso, propuesto por la Organización Mundial para la Salud, incluye como elemento necesario la seguridad en el ambiente donde se desarrolla el niño, incluido el hogar. Para lograr esta meta se requiere fortalecer las políticas públicas que favorezcan el cuidado seguro de los niños y vincular acciones entre empresa-sociedad para hacer compatible el trabajo con el cuidado seguro de los niños.

Avhengighetsfokusert EMDR – oppsummert kunnskap
Authors: Arnevik Espen Ajo , Brun Aurora , Rognli Eline Borger , Abel Kristine Fiksdal
Published: February 2025

Bakgrunn: I denne artikkelen presenterer vi en oversikt over protokoller for avhengighetsfokusert Eye Movement Desensitization and Reprocessing (AF-EMDR) og gjennomgår studier som har undersøkt effekten av AF-EMDR. Metode: Vi har gjennomført et systematisk litteratursøk og inkludert studier som undersøker bruk av AF-EMDR for å påvirke klinisk utfall knyttet til avhengighet. Resultater: Totalt tretten studier oppfylte inklusjonskriteriene. Av disse var tre randomiserte kontrollerte studier, seks kasusseriestudier og fire kasusstudier. Behandlingsprotokollene som ble identifisert, var Craving Extinguished (CravEx), Feeling-State Addiction Protocol (FSAP), Desensitization of Triggers and Urge Reprocessing (DeTUR) og Palette of EMDR Interventions in Addiction (PEIA). Kasus- og kasusseriestudiene rapporterte reduksjon i russug, rusmiddelbruk og avhengighetsadferd. Ingen av de randomiserte kontrollerte studiene viste statistisk signifikante effekter av AF-EMDR. Konklusjon: AF-EMDR har blitt utviklet og brukt klinisk i nærmere 30 år, men er i liten grad forsket på. Vår gjennomgang av litteraturen viser at det er gjort få studier med design og styrke egnet til å trekke slutninger om effekt. Det er per i dag begrenset evidens for at AF-EMDR fører til bedring av avhengighet. Oppsummeringen tydeliggjør et behov for mer robust forskning, spesielt gjennomføring av studier med større antall deltagere og kontrollert design.

Published: February 2025

STEM (Science, Technology, Engineering, and Mathematics) education is essential in preparing students for a rapidly evolving, technology-driven world. It fosters interdisciplinary learning, problem-solving, and innovation while promoting student engagement through hands-on experiences. However, challenges such as limited resources, inadequate teacher training, and curriculum constraints hinder its effective implementation. Simultaneously, youth volunteerism plays a vital role in community development, cultivating leadership, teamwork, and social responsibility among students. Integrating STEM education with volunteer activities presents an opportunity to enhance both academic and social competencies. This study investigates the perceptions and implementation of STEM education among science and mathematics teachers in Thailand, focusing on its role in promoting youth volunteerism. Sixteen teachers from Secondary School, Thailand participated through surveys and interviews. The findings highlight that while teachers recognize STEM's value in developing future-ready skills, challenges such as time constraints and institutional support limit its integration. Additionally, real-world STEM projects encourage civic engagement, yet structured programs remain underdeveloped. Teachers reported that students initially reluctant to engage in STEM activities became more motivated when involved in practical, community-based projects. To optimize STEM education and foster youth volunteerism, recommendations include enhancing professional development programs, providing institutional support, and designing curriculum frameworks that explicitly connect STEM learning with service-learning opportunities. Addressing these factors can help bridge the gap between academic knowledge and social impact, cultivating a generation of students who are both skilled professionals and responsible global citizens.
ԱՐԳԵԼԱՎԱԶՔԻ ԱՌԱՆՁԻՆ ՀԱՏՎԱԾՆԵՐԻ ՈՒՍՈՒՄՆԱՍԻՐՄԱՆ ԱՐԴՅՈՒՆՔՆԵՐԸ / THE STUDY OF INDIVIDUAL SEGMENTS OF THE RUNNING DISTANCE IN HURDLING
Authors: Harutyunyan M. A.

Hurdles is a technically complex discipline in athletics. To achieve high athletic performance, a hurdler must have excellent coordination of movements, a refined sense of rhythm, high speed, general and specific endurance, agility, and flexibility. Modern scientific research focuses on studying the biomechanical indicators of hurdlers, improving technical elements in individual segments of the distance, enhancing motor abilities, and developing innovative training methods.
The aim of the research is to analyze the proportion and correlations in overcoming individual segments of the distance among highly qualified hurdlers and their impact on athletic performance.
The objectives of the research are:
1.To study the correlation between the time of overcoming individual segments of the distance in hurdling and the overall athletic performance.
2. To analyze the Proportion of the start time, inter-hurdle segments and the finish to achieve athletic result.The analysis of specialized literature and the results of this study allow us to conclude that the high correlation with athletic performance for highly qualified men hurdlers in the segments from the start to the third hurdle, and for women up to the second hurdle, is due to high performance, a well-developed level of motor abilities, and the neuromuscular system. The time taken to overcome the segments from the third to the eighth hurdle shows an average correlation with athletic performance, while the last segments of the distance show a low correlation for both men and women. This is likely due to the onset of fatigue.

A unique two-dimensional gridded geomagnetic map of India is constructed using the geomagnetic field observations from 11 observatories of India, operated by the Indian Institute of Geomagnetism. In order to create the spatial grid, 11 spatial techniques are compared with observed magnetic field during 2011–2020. Out of the 11 known techniques of spatial interpolation, the Modified Shepard’s Method is selected as the best suitable method for interpolation. The spatial gird provides the hourly values of absolute and variations in horizontal (H) and vertical (Z) magnetic field over India. The spatial grid can be applied to higher temporal resolution of data sets as well. This map can be used to get the regional changes in the magnetic field during quiet and disturbed conditions. A user-friendly MATLAB based GUI is created for obtaining the spatial grid.

Delivering inclusive and accessible education via a change in pedagogical approach using the student voice: reducing a high failure rate module into a highly successful module
Authors: Handley Ryan , Moogan Yvonne
Published: February 2025

The need to prioritise student engagement through inclusive, student-centred education is increasingly recognised in higher education institutions across the UK. This study investigates how incorporating the student voice can transform a challenging core module within a Business Management degree. Students need to be viewed as customers and be listened to, as they invest significant time and resources into their education. Consequently, the student voice has become crucial as universities strive to achieve high NSS scores, improve rankings, and reduce attrition rates, which impact revenue. By making proactive changes with students at the heart of decision-making, this study employs a three-stage mixed-methods approach involving secondary data, pre-intervention interviews, and post-intervention focus groups to explore how student feedback informed pedagogical changes in an Accounting and Finance module. The findings highlight the value of co-creation with students, demonstrating that such engagement can enhance academic performance and lead to higher pass rates.
