UMA REFLEXÃO SOBRE A CARÊNCIA DOS ESTUDOS GEOMORFOLÓGICOS NA REGIÃO NORTE DO BRASIL
Authors: Gabriela Mendonça Silva  , Alves André Campos
Published: February 2025

A geomorfologia é um ramo do conhecimento científico que tem como principal objetivo o estudo dos processos e formas da paisagem geomórfica. O presente trabalho visa evidenciar a carência de estudos geomorfológicos na região Norte, destacando suas lacunas na produção científica brasileira. No procedimento metodológico, optou-se pela catalogação dos trabalhos geomorfológicos das universidades estaduais e federais do Norte do Brasil, utilizando as plataformas de repositório de teses e dissertações em Geografia de cada instituição, assim como, o repositório da Capes. Pôde-se constatar o baixo quantitativo das universidades nortistas na produção de geomorfologia, destacando-se os programas da UFRR e UFPA. No entanto, a maior produção brasileira sobre a região corresponde aos programas de pós-graduação do Sudeste, fora do âmbito geográfico. A partir disso, nota-se que os geógrafos físicos da região Norte têm contribuído para a baixa produtividade na produção de trabalhos geomorfológicos, permitindo que outros profissionais, inclusive de outras regiões do Brasil, explorem o tema. Recomenda-se um maior estímulo à produção científica geomorfológica na região Norte, considerando a importância da região, especialmente por abrigar parte significativa da Amazônia. A utilização de imagens de satélite e o avanço tecnológico foram destacados como facilitadores para pesquisas remotas na região, apesar dos reais desafios logísticos.

Published: February 2025

O presente trabalho objetivou analisar a variação espaço-temporal de parâmetros limnológicos da região do médio curso do Pindaré. Para este trabalho foram coletadas amostras de água em seis diferentes pontos, distribuídos em entre as cidades de Tufilândia, Alto Alegre e Bom Jardim. As coletas ocorreram durante os períodos de estiagem e chuvoso da região. Foram analisados a transparência, temperatura, oxigênio dissolvido, condutividade, pH, turbidez e nutrientes inorgânicos. Os dados foram comparados à resolução CONAMA 357/2005. A temperatura e transparência da água apresentaram maiores valores durante a estiagem e menores durante o período de chuvas. Houve variação sazonal na concentração do oxigênio dissolvido. A concentração dos nutrientes inorgânicos apresentou variação sazonal sendo mais elevada durante o período chuvoso. O pH variou de pouco ácido a pouco básico. A condutividade apresentou valores variando entre 163 µS.cm-1 a 359 µS.cm-1 sendo estes resultados superiores ao estabelecidos pela resolução CONAMA 357/2005. As analises estatísticas uni e multivariadas não indicaram variações marcantes entre os pontos e as épocas de amostragem podendo esse resultado ser afetado pela época de amostragem bem como pela dinâmica do fluxo unidirecional do rio que atua como agente homogeneizador as massas d’água.

Authors: Araujo Elania , Otaviano Praça de Souza Jonas , Cristina Clemente Machado Célia
Published: February 2025

A paisagem é resultado de uma relação entre os processos passados e atuais. Seus processos formadores agem sobre as superfícies criadas por esses eventos passados. A classificação por Unidades de Paisagens se configura como ferramenta de análise paisagística, auxiliando no entendimento e as delimitando a partir de setores homogêneos. As paisagens semiáridas apresentam uma diversidade, variando entre chapadas, planaltos, depressões e os enclaves subúmidos, objeto de estudo dessa pesquisa. É a interação dos elementos naturais que propicia a formação dessas áreas de exceção, proporcionando um diferenciado regime de chuvas, solo e vegetação. Situadas no Sertão paraibano estão as Serras Sertanejas, classificadas como um enclave subúmido. O entendimento da dinâmica natural dessa área é de grande importância, pois ali se desenvolveu uma caatinga do tipo florestal, devido a interação do conjunto de fatores abióticos. Fundamentada a partir da importância dessas áreas de exceção, foi realizada por meio da análise geoambiental a classificação por unidade de paisagem das Serras Sertanejas paraibanas. Identificou-se uma particularidade quanto aos seus aspectos geoambientais, a interação entre a geologia, geomorfologia e o clima permite a existência de um ambiente individualizado dentro do Semiárido, proporcionando um regime de precipitação diferente e um desenvolvimento de uma vegetação local, com características distintas da vegetação habitual de caatinga. Foram identificadas quatro Unidades de Paisagens: Pedimento, Topo Convexo, Topo Plano e Escarpa. A análise integrada dos elementos fisiográficos aliada ao seu relevo de altitude média e superfícies aplainadas, faz do complexo de Serras uma área de exceção dentro do Semiárido.

Authors: S Anitha , Saxena Lavi
Published: February 2025

Life skills are adaptable and positive behaviours that help people handle daily life (WHO). It turns knowledge into virtue. Adolescence is crucial to development. Stress and tension accompany the transition from infancy to adulthood. It involves fast physiological and psychological maturity. These are also years of risk-taking, problem-solving, important choices, peer pressures, and stress management. Thus, it marks a life turning point and prospective growth. Physiological, emotional, and sociocultural aspects of teenagers must be addressed. The bigger requirement is to teach teenagers life skills to handle obstacles and demands. Life skills grow dynamically throughout time. One needs numerous talents to handle any event in life every day. Due to their physical and intellectual abilities, adolescents are productive society members. Most teenagers are unable to maximise their potential owing to improper environments. They constantly do antisocial things and ruin their lives. Educational reform should prioritise life skills to make teenagers' lives useful and develop their potential. The researcher compares life skills education for state and CBSE pupils in this report.

Authors: S Jeena Rani M , Ravitosh Ravitosh
Published: February 2025

This research examines how personality qualities and socioeconomic circumstances affect stress levels and stress-related symptoms in challenging-job workers. The study included 34 psychiatric nurses. Women made up 68% of the sample and averaged 35.18 years old, while men averaged 32.25. The study examined how gender, age, and work tenure affected stress and symptoms, as well as how personality characteristics and stress interacted. The research found that female nurses' stress increased with age and service, whereas male nurses' stress increased at the start of their employment. Personality factors correlated strongly with stress and its effects. Researchers found that socioeconomic pressures affected individuals with poor social presence, empathy, independence, and intellectual efficiency. Less psychological insight, career direction, tolerance, and well-being were linked to more severe stress symptoms. These people were also more feminine. These results show that gender variations in stress adaptation are considerable and that personality traits mitigate socioeconomic stresses. This research emphasizes personalized mental health therapy and social support. These methods should consider participants' socioeconomic status and personality.Socioeconomic Stressors
Applications and Implementations of Pairing-Free Directed Signature Techniques in Real-World Scenarios
Authors: G Sajitha V , Saxena Dharmendra
Published: February 2025

Vehicular Ad-hoc Networks (VANETs), a type of Internet of Things system, allow groups of cars to communicate with one another and with traffic monitoring devices, improving traffic safety and quality of life. In a VANET, vehicles are used by drivers and the system controller to report not only their own status but also that of the road, traffic, and environment. Since VANET networks are open to the public, there is a significant influx and outflow of automobiles. This feature has led to the emergence of two top-tier requirements for VANET security: first, that systems ensuring message security must be quick, and second, that vehicles in a VANET must be held responsible for the accuracy of the information they provide. This study proposes an efficient pairing-free signature technique for VANETs that protects against signer identity fraud, even in situations of insider attacks, without the need for a tamper-proof device.

Review of the Use of Bacteriophages in Biotechnology
Authors: Radi Nisreen Kadum , Sahi Nebras Mohammed , Hmood Samreh Shaker , Sahi Marwah Mohammed , Radi Narges kazem
Published: February 2025

Background:Bacteriophages are ubiquitous entities that exhibit a specialty towards one or more host strains. They are the most prevalent entities on Earth, surpassing bacteria in quantity by a factor of ten. We can identify two categories of phages: lytic and temperate. This is about phages that can add their genetic material to the host genome. This makes a prophage that copies itself inside the host cell and may protect it from other phages of the same species that might try to infect it. Alternatively, lytic phages, which are of significant importance in biotechnology, encourage the host cell to undergo lysis after their reproductive cycle. In their lysogenic state, they can disseminate genes that provide antibiotic resistance to bacteria via horizontal gene transfer. Moreover, phage therapy has garnered support from the scientific community due to its distinctive ability to address issues associated with biofilm formation and microbial regulation that other prevalent methods struggle to resolve effectively. Bacteriophages are advantageous as they offer a feasible and promising alternative. This study aims to provide the latest knowledge on the application of phages for pathogen biocontrol in industrial and healthcare environments.

Gatekeeping et dynamique de circulation des informations virales et toxiques: Une étude de deux groupes WhatsApp en Côte d'Ivoire
Authors: Karimu Waliyu
Published: February 2025

RÉSUMÉ: La démocratisation de l'Internet facilite le recours massif aux applications de messagerie instantanée comme WhatsApp. Celle-ci, très prisée mondialement, favorise la socialisation et le partage d'informations variées. Cependant, en l'absence de toute prise de conscience, certains des contenus qui sont abondamment relayés dans les groupes WhatsApp peuvent conduire à la violence, à la haine, et pourraient être potentiellement dangereux pour la cohésion sociale dans un contexte de fragilité politique comme celui de la Côte d'Ivoire. Cette recherche, menée à l'aide d'une approche qualitative, repose sur un corpus d'une quinzaine d'informations provenant de deux groupes WhatsApp. Nous mobilisons ici le concept de gatekeeping. Nous parvenons à la conclusion que WhatsApp charrie d'abondants messages, mais comporte aussi des limites, ne parvenant pas à freiner la propagation de contenus toxiques. ABSTRACT: The democratization of the Internet has facilitated the widespread use of instant messaging applications such as WhatsApp. This platform, widely popular worldwide, encourages socialization and the sharing of diverse information. However, without sufficient awareness, some of the content that circulates on WhatsApp can incite violence, hatred, and potentially undermine social cohesion, particularly in politically fragile contexts like that of Côte d'Ivoire. This qualitative study is based on a corpus of about fifteen pieces of information from two WhatsApp groups. We employ the concept of gatekeeping in our analysis. We conclude that while WhatsApp serves as a vehicle for a vast array of messages, it also has significant limitations in controlling the spread of toxic content.
The gated, the gatekeepers and the 'gatekeeper state' : Une approche par le bas du problème de la circulation des personnes et des biens au sein de la CEDEAO
Authors: Hahonou Eric Komlavi
Published: February 2025

RÉSUMÉ: Cet article examine les modalités et les conséquences des pratiques de gatekeeping sur la circulation des personnes et des biens dans la Communauté Économique des États de l'Afrique de l'Ouest (CEDEAO). A partir d'un terrain réalisé auprès de pêcheurs migrants à la frontière Bénin-Niger, l'auteur décrit et analyse ces pratiques en croisant les points de vue des contrôlés (gated) et des « contrôleurs d'accès » (gatekeepers). Il montre que les contrôles aux frontières opérés par les agents de l'État sont cosmétiques et peu effectifs. Les divers types de contrôle d'accès, dont la création de postes de contrôle fictifs, se caractérisent par des formes de racket systématique qui renvoit essentiellement à des logiques d'accumulation de rente. Même si les « contrôlés » disposent de marges de manœuvre pour négocier leur passage aux points de contrôle, les pratiques de gatekeeping au quotidien sont principalement orientées vers la prédation et sont ancrées dans l'économie morale de la corruption. La gouvernance de la frontière Bénin-Niger illustre la nature extractive des relations État-citoyens et explique le paradoxe du non-respect des engagements des États membres de la CEDEAO d'assurer la libre circulation effective des biens et des personnes dans l'espace communautaire en s'appuyant sur les théories du gatekeeper state, du patrimonialisme et de la corruption. ABSTRACT: This article examines the modalities and consequences of gatekeeping practices on the circulation of people and goods in the Economic Community Of West African States (ECOWAS). Based on fieldwork carried out among migrant fishermen at the Benin-Niger border, the author describes and analyzes gatekeeping practices from the points of view of both the "gated" and the "gatekeepers." The article shows that controls carried out by gatekeepers are mostly cosmetic and ineffective. Gatekeeping and gate-making practices (creation of fictitious checkpoints) are characterized by systemic forms of racketeering operated by gatekeepers, who essentially relate to the logic of rent accumulation. Even if the "gated" have room to negotiate their passage through checkpoints, gatekeeping practices are mainly oriented toward predation and are anchored in the moral economy of corruption. The governance of the Benin-Niger border illustrates the extractive nature of state-citizen relations and explains the paradox of noncompliance with the commitments of ECOWAS member states to ensure the effective free movement of goods and people in the regional community by relying on theories of the "gatekeeper state," corruption and patrimonialism.

This study examines the impact and effectiveness of educational broadcast methods implemented during the COVID-19 pandemic for secondary school students in Asaba, Delta State, Nigeria. Following the outbreak of COVID-19 in March 2020 and subsequent school closures, the Delta State Government adopted various educational broadcast methods and e-learning approaches to ensure educational continuity. Through a systematic analysis, this research investigates the level of utilization of educational broadcast methods, evaluates opportunities provided by the state government, identifies implementation challenges, and examines factors influencing technology acceptance among secondary school students. The study employs both quantitative and qualitative methodologies to assess the effectiveness of these emergency educational measures. Findings reveal significant variations in the utilization of educational broadcast methods among students, highlighting disparities in access and adoption. The research also uncovers critical challenges including inadequate internet facilities, insufficient teacher training in educational broadcasting methods, and technological infrastructure limitations. This study contributes to the growing body of knowledge on emergency remote education in developing countries and provides valuable insights for policymakers and educators in implementing effective distance learning solutions during crisis periods. The findings emphasize the need for improved technological infrastructure, enhanced teacher training programs, and more inclusive educational broadcast strategies to ensure equitable access to quality education during emergencies.
Network intrusion detection using hybrid approach
Authors: Ashwani Attri  , Priyanka Gundeboyena  , Vaishnavi Chigurla  , Soumika Moluguri  , Nithin Kasoju
Published: February 2025

This project presents a new approach to network security by combining two types of detection techniques: signature-based and anomaly-based. The signature-based method helps catch known threats by recognizing attack patterns, while the anomaly detection technique, powered by machine learning (specifically Isolation Forest), identifies unusual or new network behaviors that might signal emerging threats. After rigorous testing with benchmark datasets, the system has shown to be more accurate and generates fewer false alarms than traditional methods. It also includes useful features like storing detected anomalies for later review and sending real-time alerts to ensure prompt responses. This research emphasizes how blending these detection methods can make network intrusion systems more effective, with potential future improvements like integrating real-time monitoring or deep learning for even better performance. The findings are currently being prepared for publication.

A comparative study of four schools of jurisprudence is urgently needed to overcome legal uncertainty in Indonesia regarding the return of inherited assets if the marriage is annulled. The increasing number of marriage annulments in 2024, coupled with differences in interpretations of schools of thought and positive law, makes this study crucial for creating legal certainty, justice and harmonization between Islamic law and positive law in Indonesia. This study will recommend practical solutions to avoid conflict and protect the rights involved. This research uses a normative method with a literature study approach to analyze Islamic law regarding the return of inherited assets when a marriage is annulled. Comprehensive law for fair dispute resolution and the results of the discussion are that the Shafi'i and Maliki schools have different opinions regarding the withdrawal of offerings before the wedding. Shafi'i takes into consideration the giver's intentions, allowing withdrawal if it is for marriage and annulled, despite internal differences of opinion. Malikis are stricter, generally prohibiting withdrawals except from father to son, with the potential exception of pre-covenant dowries. These differences, plus internal differences of opinion within the two schools, demonstrate the complexity of this issue. Implementation in Indonesia faces challenges: differences in sectarian interpretations, difficulty proving intent, gender inequality, and a lack of a modern legal framework. Comprehensive legal reform, increasing legal awareness, and harmonization of Islamic-positive law are very necessary to create justice.

Multivariate Optimization of a HS-SPME+GC×GC-MS Procedure to Determine Fingerprints of the Volatile Fraction of Lager Beers
Authors:   Instituto de Química, Universidade Estadual de Campinas, Cunha Isabela , Augusto Fabio
Published: February 2025

In this work we describe the optimization and application of a HS-SPME-GC×GC-MS method to assess the volatile fraction of Lager beers. The method development was performed using a combination of univariate and simultaneous multivariate approaches. Before use, canned beer samples were decarbonated by a freeze+taw procedure designed to minimize loss of volatile compounds and ensure complete elimination of CO2 before extraction. The GC×GC cryogenic modulation conditions were optimized considering overall peak resolution and widths, where for the HS-SPME step parameters a multivariate approach using a Doehlert matrix was adopted, targetting the maximization of the total integrated peak area. The results of the multivariate optimization pointed that the extraction efficiency was maximum with 40 °C and 30 min as extraction temperature and time respectively. Using these optimized extraction conditions, it was possible to detect from 240 to 270 chromatographic peaks on the volatile fraction of the samples; among them 85 were identified. These results point out that careful optimization of operational parameters render HS-SPME combined to GC×GC-MS as a powerful tool to retrieve qualitative and quantitative information regarding the composition of beers.

INTRODUCTION. Vaccination against smallpox was discontinued in 1980 following the success of the World Health Organization’s Smallpox Eradication Programme. Consequently, more than half of the current world population lacks immunity to orthopoxviruses pathogenic to humans. Since 2022, several countries have been reporting outbreaks of mpox (previously known as monkeypox), which necessitates developing new small molecules active against orthopoxviruses.

AIM. The aim was to evaluate the safety and tolerability of NIOCH-14, a Russian anti-smallpox medicinal product, after oral administration in a phase I clinical trial.

MATERIALS AND METHODS. The clinical trial was conducted in 90 healthy volunteers at the Federal State budgetary Institution of Healthcare ‘Medical and Sanitary Unit No. 163 of the Federal Medical and Biological Agency’ in accordance with Protocol No. NIOCH-01/20 ‘An open, simple, randomised study of the safety, tolerability, pharmacokinetics of NIOCH-14 in volunteers aged 18–50 years in parallel groups’. Investigators used a standard set of clinical, laboratory, and instrument-based testing methods. The clinical trial included six experimental groups of 15 subjects each. Groups 1, 2, and 3 received NIOCH-14 as a single oral dose of 200, 600, and 1200 mg, respectively. Groups 4, 5, and 6 received NIOCH-14 at daily oral doses of 200, 600, and 1200 mg/day, respectively, for 6 days.

RESULTS. After single and repeated administration of NIOCH-14 at doses of 200, 600, and 1200 mg to volunteers, the study did not demonstrate any changes in the blood test results (erythrocyte, leucocyte, platelet, and differential leucocyte counts; haemoglobin levels; erythrocyte sedimentation rate values; alanine transaminase, aspartate transaminase, and alkaline phosphatase activity levels; total protein, total bilirubin, glucose, creatinine, urea, and C-reactive protein levels; prothrombin time ratios; thymol turbidity). Similarly, the urinalysis results remained unaltered throughout the entire observation period. No adverse events were observed in volunteers receiving NIOCH-14 at all single doses or repeated doses of 200 and 600 mg. One volunteer receiving the investigational medicinal product at a repeated dose of 1200 mg/day experienced transient epigastric pain on days 2 and 5.

CONCLUSIONS. The physical examination, haematology, blood chemistry, and urinalysis results did not reveal any pathological changes in healthy volunteers. The investigational medicinal product, formulated as hard gelatin capsules containing 200 mg of NIOCH-14 and excipients, demonstrated a favourable safety and tolerability profile.

REGISTRATION. This clinical trial is registered at ClinicalTrials.gov (NCT05976100).
Measuring Grading Standards at High Schools: A Methodological Contribution, an Example, and Some Policy Implications
Authors: Johnson David R.
Published: February 2025

At schools with low grading standards, students receive higher school-awarded grades across multiple courses than students with the same skills receive at schools with high grading standards. I show school grading standards vary substantially, enough to affect post-secondary opportunities, across high schools in Alberta, Canada. Schools with low grading standards are more likely to be private, rural, offer courses for students returning to high school after dropping out, have smaller course cohorts, have a smaller percentage of lone-parent households, and have a larger percentage of well-educated parents. The article makes a useful methodological contribution in clarifying the assumptions needed to estimate and interpret a measure of grading standards from course-year-school observations of average school-awarded grades and average external examination grades.
中国古代建筑模数-佛光寺东大殿
Authors: xiaoggang Xu
Published: February 2025

摘 要：佛光寺东大殿在中国古代建筑史的地位不言而喻。通过材与开间、面阔、进深等比较，拟合营造尺为314.5毫米。符合唐代大小尺制度，每大尺是12小寸，也是12小寸。大殿没有使用材份制，而使用了建筑模数。基本模数为2尺，合24小寸。8小寸是分模数，是基本模数的3分之1，用于材宽、间广划分。0.4小寸是基本模数的30分之1，也是分模数，用于材。此手法与现代建筑模数非常相似。建筑外形及大木作构架符合简明比例和经典比例。关键词：佛光寺东大殿；建筑模数；营造尺；比例；大木作；衰分Abstract: The significance of the East Hall of Foguang Temple in the history of ancient Chinese architecture is self - evident. Through the comparison of the cai(Similar to dimension lumber) with the bay width, facade width, and depth, etc., the construction ruler (Yingzao chi) is fitted to be 314.5 millimeters. It conforms to the long and short ruler system since the Tang dynasties. Each ruler (1 chi) is 10 cun, and each chi is divided into 12 small cun. The construction module was adopted. The hall did not use the cai-fen system but adopted an architectural modular system. The basic module is 2 chi, equivalent to 24 small cun. Eight small cun is a infra module, one - third of the basic module, used for dividing the width of the cai and the bay width. 0.4 small cun is one - thirtieth of the basic module and also a infra module, applied to the cai. This approach bears a striking resemblance to modern architectural modular systems. The exterior of the building and its large - scale timber framework adhere to concise and classic proportions. The exterior of the building and its Damuzuo adhere to concise and classic proportions.Keywords: The East Hall of Foguang Temple;Architectural Modular System; construction ruler (Yingzao chi); Proportion; Damuzuo(greater structural carpentry); Cui fen(Proportional Allocation, 衰分)
