PROTOCOLOS DE FOTOBIOMODULAÇÃO NO TRATAMENTO DE ALTERAÇÕES NEUROSSENSORIAIS DECORRENTES DE CIRURGIA ORTOGNÁTICA: revisão da literatura
Authors: Girotto Amanda Chiulo , Marson Giordano Bruno de Oliveira
Published: November 2023

Anomalias no complexo craniomaxilofacial, resultantes de alterações no desenvolvimento do neurocrânio ou viscerocrânio, podem surgir desde o período intrauterino ou devido a fatores etiológicos ao longo da vida. A cirurgia ortognática, visando corrigir tais irregularidades, frequentemente envolve técnicas como a osteotomia sagital do ramo mandibular (BSSO) para ajustar maloclusões. No entanto, déficits neurossensoriais após BSSO são comuns, com 1-2% dos casos persistindo por longos períodos, afetando a qualidade de vida. O nervo alveolar inferior (NAI) é muitas vezes danificado durante a BSSO, causando sensações atípicas ou dormência. Apesar da recuperação neurossensorial muitas vezes ocorrer espontaneamente, há uma busca por métodos que acelerem esse processo. A fotobiomodulação (FBM) surge como uma abordagem não invasiva promissora. Este trabalho tem como objetivo realizar uma revisão narrativa da literatura sobre os protocolos de uso da fotobiomodulação (FBM) como ferramenta auxiliar no tratamento das neurossensoriais decorrentes de cirurgia ortognática. A FBM é eficaz na recuperação neurossensorial pós-cirurgia ortognática envolvendo o NAI. A técnica, minimamente invasiva, tem seu uso recomendado no pós-operatório, com aplicação intraoral e extraoral. Contudo, a falta de um protocolo padrão para FBM evidencia a necessidade de mais pesquisas para esclarecer seus efeitos e eficácia no tratamento de distúrbios neurossensoriais pós-operatórios.

THE SUBLIME IN KEATS' POETRY: A COMPARATIVE STUDY WITH BLAKE AND BYRON
Authors: Singh Dr Pankaj Kumar
Published: November 2023

This comparative analysis explores the concept of the sublime in the poetry of Lord Byron, William Blake, and John Keats, providing new perspectives within the Heartfelt evolution. The review deconstructs the profound and philosophical foundations of the sublime through an analysis of each artist's individual work, highlighting the artists' distinctive approaches to outfitting the sublime to evoke extraordinary feelings, prompt existential reflection, and defy conventional norms. The richly woven artwork of the Heartfelt period is enhanced by the exotic and gloomy sublime of Keats, the visionary otherworldliness of Blake, and the often uncertain and defiant translation of the sublime by Byron. Their works captivate with distinct and unmistakable symbolism and continue to influence writing and craftsmanship by providing a sophisticated exploration of nature, otherworldliness, and the human condition.
Кодиране на редки болести в България и приложение на номенклатурата на Orphanet
Authors: Димитров Костадин , Стефанов Георги , Митова Елена , Стефанов Румен
Published: November 2023

Въведение: Международната статистическа класификация на болестите (МКБ) не е адаптирана за предоставяне на изчерпателни епидемиологични данни по отношение на редките болести, което затруднява обмена на информация, забавя времето до поставяне на точна диагноза и вземането на решения, базирани на доказателства. Номенклатурата разработена от международната референтна база данни за редки болести Orphanet, позволява прецизно кодиране с помощта на ORPHA кодове. Цел на това проучване е установяване на практиките и предизвикателствата, свързани с кодирането на редки болести в експертни центрове в България

Материал и методи: Проучването е насочено към медицински специалисти, работещи към официално обозначените експертни центрове за редки заболявания в България. За целта на проучването е създадена анкетна карта, съдържаща 10 въпроса.

Резултати: Номенклатурата за редки болести на Orphanet е посочена като втората по честота на използване след МКБ-10, но се прилага в практиката от по-малко от половината отговорили. По-голямата част от респондентите съобщават, че са запознати с нея. Ускорено въвеждане на кодиране по Orphanet би могло да се осъществи при адаптиране на софтуерните системи, използвани в здравеопазването. Обучение, подобрена комуникация с Националния регистър на пациенти с редки болести и законодателна подкрепа са посочени като важни фактори за по-широкото използване на ORPHA кодовете в България.

Заключение: Ключово за използването на ORPHA кодовете е провеждане на информационна кампания за популяризиране на ползите от приложението им, разработване на специфична програма за обучение на специалисти в експертните центрове, подобряване на партньорството с Националния регистър за пациенти с редки болести, както и ангажирането на здравните власти с цел интегриране на номенклатурата на Orphanet в Националната здравноинформационна система, до която имат достъп всички лечебни заведения в България.

Радченко О. К., Гогаєв К. О., Аскеров М. Г., Воропаєв В. С. Кутові параметри осередку деформації під час прокатування металевих порошків (огляд)

Зважаючи на складність процесу прокатування порошків, а також  те, що існує потреба прогнозування режимів прокатування нових порошків та складних порошкових систем, встановлення кутових параметрів осередку деформації є актуальною задачею. Особливо важливим є знання кутових параметрів при оптимізації режимів прокатування у випадках коли ця операція є останньою при одержанні готового продукту. В огляді розглянуто кутові параметри, що характеризують симетричний осередок деформації при прокатуванні металевих порошків у валках з гладкою поверхнею. Показано, що прокатування металевих порошків є складним процесом, для опису якого в різний час були запропоновані різні кутові параметри. Розглянуто 11 кутів, їх назви, опис, методи визначення та розрахунку. Більшість з них мали кілька назв з яких обрані найбільш вдалі. Для трьох з них запропоновані нові назви, що повніше характеризують їх фізичну сутність. Проаналізовано величини кутів для різних порошків та різних методик їх вимірювання. Встановлені параметри від яких залежать кути, що розглядаються. Найбільш повно досліджено кут захвату порошку. Для кута захвату, за наявними літературними даними, параметри від яких він залежить ранжовані за їхньою значимістю. У порядку зменшення ступеня впливу досліджених параметрів кут захвату залежить від коефіцієнта тертя валок-порошок, коефіцієнта бічного тиску; відносної насипної щільності порошку; ширини бункера та зовнішнього зусилля, що прикладають до порошку. Залишився недослідженим вплив на кут захвату фізико-механічних властивостей матеріалу частинок. До існуючих кутів доданий кут випередження, який у парі з кутом відставання охоплює увесь осередок деформації. Показано, що співвідношення кутів відставання та випередження може бути використане для характеристики таких ознак осередку деформації як симетричність та наявність переднього натягу, а також може характеризувати пластичні властивості матеріалу частинок.
Підвищення ресурсу пресового інструменту шляхом комбінованої технології відновлення

Гринь О. Г., Трембач І. О., Жаріков С. В. Підвищення ресурсу пресового інструменту шляхом комбінованої технології відновлення

Аналіз літературних даних показав, що для відновлення пресового інструменту використовуються теплостійкі сталі системи легування Cr-W-Mo з карбідним зміцненням (3Х3М3Ф, 30Х2В8Ф, 40Х12В4К2Ф) та сталі з інтерметалідним зміцненням (03Н15К9М5ТЮ, 04Н18М4К11, 10Х9К3В2МФБР). Під дією змінного температурно-циклічного впливу в поверхневому шарі наплавленого металу з карбідним зміцненням відбувається розпад мартенситу і коагуляція карбідів, що зменшує твердість, та, відповідно, прискорює знос. Сталі з інтерметалідним зміцненням перспективні за своїми властивостями, але водночас дефіцитність та висока вартість основних легуючих елементів обмежує їх застосування. Тому актуальним питанням є розробка економно легованої сталі та технології відновлення пресового інструменту. Встановлено, що максимальна температура поверхні пуансону досягає 650-750 °С при встановленому режимі роботи і напруженому стані. Аналіз експлуатації пресового інструменту показав, що матеріал для їх виготовлення повинен відповідати комплексу вимог: висока міцність (не менше 1000 МПа), висока теплостійкість, достатня в'язкість, високий опір термічної втоми (розгаростійкість), хороша окалиностійкість та висока прогартовуваність. З метою підвищення надійності і довговічності пресового інструменту для деформування сплавів на основі міді запропонована комбінована технологія відновлення, що полягає в наплавленні металу на попередньо алітовану поверхню. При поєднанні технологій хіміко-термічної обробки (алітування) та наплавлення з використанням самозахисного порошкового дроту відбувається насичення наплавленого металу алюмінієм і його сполуками в результаті розчинення в ньому багатих алюмінієм фаз, що сприяє зменшенню окалиноутворення та має забезпечувати високу жаростійкість наплавленого шару.

Алієв І. С., Левченко В. М., Чучин О. В., Картамишев Д. О., Коцюбівська К. І. Верхня оцінка силових параметрів поперечно-кутового видавлювання

У роботі розглянуто процес комбінованого поперечно-кутового видавлювання відростка під кутом у матриці з нахиленою ділянкою. Моделювання силового режиму процесу комбінованого видавлювання методом верхньої оцінки виконано з використанням універсальних кінематичних модулів, що дозволило незалежно оцінити вплив геометричних параметрів на тиск деформування. Підтверджено можливість доповнення приведених тисків при послідовному комбінуванні схем видавлювання. Встановлено, що вибір розрахункової схеми та аналіз процесу необхідно вести в залежності від відносної висоти осередку деформації. Розрахункові формули для плаского поперечного видавлювання, отримані методом верхньої оцінки, показують результати, близькі до експериментальних даних та до аналогічних рішень для інших задач плаского деформування в процесах доштампування та осадки, що відрізняються видом поля швидкостей та умовами тертя на границях. Залежності для тиску деформування при кутовому видавлюванні в матриці з нахиленою твірною отримано з використанням трикутного модуля, для якого описано методику розрахунку компонентів тиску на лініях розриву швидкостей. Графічним аналізом залежності приведеного тиску встановлено, що найбільший вплив на рівень тиску має параметр – відносна товщина відростка h/s, що характеризує ступінь обтиснення металу. Рекомендації щодо розрахунку силових параметрів поперечно-кутового видавлювання можуть бути використані при проектуванні процесів видавлювання як деталей з відростками, так і порожнистих конічних виробів.

Podlesny S. V. Modern educational trends and technologies for training engineers for Industry 4.0

The fourth industrial revolution, also known as Industry 4.0, is transforming the manufacturing industry and creating a demand for highly skilled process engineers. To meet this demand, educational institutions must adapt to the changing needs of environmental science and provide education that prepares students for the challenges of Industry 4.0. This article discusses modern educational trends and technologies for training materials processing engineers for Industry 4.0. One of the trends in modern education is the adoption of interdisciplinary curricula. Interdisciplinary curricula also prepare materials processing engineers to work in cross-functional teams. Project-based learning, an approach to education that emphasizes learning through projects rather than traditional lectures, is an effective way to prepare material processing engineers for Industry 4.0 as it allows students to apply their knowledge and skills to real-world problems. Virtual and augmented reality technologies are becoming more and more popular in education. These technologies provide immersive learning. Artificial intelligence is another technology that is transforming the manufacturing industry. Materials processing engineers must have a basic understanding of artificial intelligence in order to work effectively in Industry 4.0. Educational institutions can incorporate artificial intelligence into their curricula by teaching courses in machine learning, data analysis, and robotics. Schools should partner with industry to provide students with hands-on experience and familiarity with real manufacturing processes. Educational institutions must adapt to the changing demands of industry and provide training that prepares students for the future of work.

Марков О. Є., Молодецький В. В., Зінській В. М., Абхарі П.Б. Експериментальне дослідження нового процесу деформування поковок типу гільз

Проведено дослідження нового способу виготовлення пустотілих гільз. Запропонований метод полягає в деформуванні порожнистої заготовки з дном без оправки. Запропоновано методику проведення експериментальних досліджень на основі закону подібності. Методика призначена для визначення подовження, заковування внутрішнього діаметра та збільшення товщини стінки порожнистої заготовки при деформуванні пустотілих поковок з дном без використання оправки. Варіювали таким параметром – діаметр отвору пустотілої заготовки, який змінювався в діапазоні 0,3 ... 0,8. Було встановлено діаметр отвору пустотілої заготовки, який зменшується при деформуванні розробленим методом. Були встановлені закономірності інтенсивності витяжки та збільшення товщини стінки пустотілої заготовки. Було запропоновано параметр для визначення ступеня витяжки порожнистої заготовки. Було зазначено, що при збільшенні діаметра отвору інтенсивність подовження порожнистої заготовки підвищується та зменшується ступінь закриття внутрішнього діаметра. Визначальною закономірністю досліджених схем деформування є те, що значення витяжки порожнистої заготовки мало змінюється залежно від ступеня деформації при однакових вихідних геометричних параметрах порожнистої заготовки. В результаті було визначено ефективну подачу, яка підвищує ступінь витяжки порожнистої заготівлі та зменшує ступінь заковування внутрішньої порожнини. Ефективна подача повинна бути в діапазоні 10...15% від вихідного діаметру заготовки. Ці результати були встановлені на зразках із свинцю з додаванням сурми. Також встановлено, що при діаметрі отвору пустотілої заготовки приблизно 0,55 від діаметра заготовки відбувається інтенсивне збільшення товщини стінки заготовки. Похибка отриманих експериментальних результатів становить 7...11%. Встановлені залежності дозволяють визначати кінцевий діаметр отвору пустотілої заготовки. Результати дослідження дозволили встановити, що деформування порожнистих заготовок без оправки є можливим. Розроблений спосіб розширює технологічні можливості процесів виготовлення поковок типу гільз.

Mustakabali wa Bara la Afrika umekuwa suala la msingi katika maudhui ya riwaya ya kisasa ya Kiswahili. Fasihi ya kimajaribio inayoakisi hali za kidistopia inachora taswira hasi za mustakabali wa Bara la Afrika. Mazingira ya kidistopia ni mandhari yanayokabiliwa na kila aina ya matatizo au uovu uliokithiri ambayo huwa ya kiubunifu. Dhana hii hutumiwa kueleza jamii ambayo sheria zake hubadilishwa na kuishia kuwa za kuwadhalilisha wanajamii kupita kiasi. Kwa ujumla, wanajamii wanaojipata kwenye ulimwengu wa aina hii huwa kwenye njiapanda. Wanajamii hao huwa wamekwisha poteza tumaini la kuishi kutokana na dhuluma zinazowakabili. Baadhi yao hutamaushwa na ugumu wa maisha na kutamani kuangamia au kujiangamiza ili kuepuka ulimwengu huo wa shida. Kazi za fasihi zinazofuata mkondo wa kidistopia hudhamiria kutoa tahadhari au kuhamasisha jamii kuwajibika ili kuepuka maangamizi yanayokuja. Kazi hizo ni za utabiri wa mambo yanayoweza kutokea baadaye. Makala hii inakusudia kuonyesha jinsi taswira ya kidistopia inavyojitokeza katika riwaya ya kimajaribio ya Kiswahili kwa kutumia Nadharia ya Usasabaadaye ilioasisiwa na Linda Hutcheon na kufafanuliwa zaidi na Patricia Waugh. Riwaya mbili za kimajaribio; Dunia Yao (2006) ya Said Ahmed Mohamed na Bina-Adamu! (2002) ya Kyallo Wadi Wamitila zilitueliwa kimaksudi ili kuonyesha jinsi taswira ya distopia inavyobainika. Utafiti ulifanywa maktabani. Data ilikusanywa kutokana na usomaji wa kina wa riwaya teule ulioongozwa na mihimili ya Nadharia ya Usasabaadaye. Data iliyokusanywa ilichanganuliwa na kuwasilishwa kwa njia ya kimaelezo kwa mujibu wa Nadharia ya Usasabaadaye. Matokeo ya utafiti yanabainisha kuwa waandishi wana sababu za kimsingi za kusawiri mandhari ya kidistopia ili kutoa taswira kamili ya nchi za Kiafrika katika muktadha wa baada ya ukoloni chini ya utandawazi, mfumo wa soko huria, ubeberu mpya, ubinafsi, taathira za kigeni na uporomokaji wa kasi wa nguzo za maisha ya Kiafrika

Primary data was collected using structured questionnaires administered to heads of risk management and secondary data from financial statements were considered. The findings revealed that liquidity risk has a negative and insignificant effect (β=-0.093, p=0.317), credit risk has a positive and significant effect (β=0.159, p=0.023), and operational risk has a negative and insignificant effect on the financial performance (β=-0.140, p=0.463) of DT-SACCOs in the Mt. Kenya region. DT-SACCOs should strive to maintain optimal liquidity and tighten their credit risk and operational risk management practices.
Efficient Optical OFDM System Resilience to Indoor Wireless Multipath Channels
Authors: Leftah Hussein
Published: November 2023

This article presents a developed intensity modulation/direct detection (IM/DD) optical orthogonal frequency division multiplexing (O-OFDM). More precisely, the presented C-O-OFDM is based on the C-transform as a unitary orthogonal transform instead of the state-of-the-art discrete Fourier transform (DFT). Due to the properties of the real C-transform, Hermitian symmetry (HS) is not required to produce real OFDM samples. Therefore, the proposed scheme supports twice the input symbols compared to conventional DFT-based OFDM system. Real data mapping and DC bias technology is considered to evaluate the performance of the presented scheme over optical wireless multipath. The simulation results shows that the proposed C-O-OFDM is more resilience to multipath phenomena than the competitive DFT-O-OFDM and DHT-O-OFDM schemes for similar bit rate. The proposed scheme achieves about 22 dB signal-to-noise ratio (SNR) gain in comparison with the DFT-O-OFDM and about 2.5 dB SNR gain in comparison with the DHT-O-OFDM scheme.

Authors: Srivastava Sneha , Sureka Ritu K.
Published: November 2023

The present study reviews the Maternal Nutrition knowledge of health care providers (ANMs and ASHAs) of Primary Health Centers (PHCs) and Community Health Centers (CHCs) and attempts to find out the existing gaps in their knowledge level related to maternal nutrition as well as discusses strategies to bridge those gaps. Good nutrition is the core pillar for human development and its necessity varies with respect to age, gender and during physiological changes such as pregnancy which is a critical phase in a woman's life when the expectant mother needs optimal nutrients to support the developing fetus. Awareness about appropriate nutrition during pregnancy is a serious concern and lack of it may lead to child morbidity and mortality. Therefore it is imperative to address this issue properly in various government policies and schemes. ICDS scheme initiated by Government of India is a major step in this regard which provides nutrition and health education, supplementary nutrition, family planning tips etc. to the pregnant women. The Anganwadi workers are the basic functionaries of the ICDS scheme and their services (providing counseling, supplementary nutrition, distribution of Iron & Folic acid tablets) are transmitted to the beneficiaries through a channel of Anganwadi centers (AWCs). Keeping the above background in mind relevant literature such as journals, newspapers, articles, research papers from Scopus, Pub Med, research gate, and Google scholar related to national and state policies pertinent to maternal nutrition were reviewed to find out the existing gaps in the knowledge level of health care providers. It is concluded from the study that maternal nutritional needs have to be prioritized in government health programmes and strategies to improve the status of expectant mothers need to be implemented to address nutritional challenges. Government schemes can be strengthened by promoting integration of services, ensuring effective procurement mechanisms for supplementary nutrition and food supplements, establishing regional training facilities and strengthening program monitoring and evaluation.
Effect of Moisture Adsorption on Low-Speed and Moderate-Speed Braking: Effect on In-Stop Friction Coefficient and Low Frequency Noise

Copper-free NAO disc pads of passenger cars were investigated for a combination of prior braking conditions and moisture adsorption influencing in-stop friction and noise during low-speed stops, and in-stop-friction during moderate-speed stops. Prior braking conditions and moisture adsorption strongly influence subsequent in-stop friction behavior and noise at room temperature. The low-speed in-stop friction behavior looks totally different from that of moderate-speed stops. The low-speed in-stop friction increasingly oscillates with increasing moisture adsorption and goes down towards the end of a stop, which is accompanied by increasing low-frequency noise.

The moisture content needs to be quantified/specified to obtain repeatable/reproducible brake test results as the moisture is an unintended and uncontrolled ingredient of a friction material. As the disc surface roughness increases due to prior braking conditions, the friction coefficient of low-speed stops is found to decrease. The changing friction coefficient is explained by the nature of the friction film and its interactions with moisture.
Standalone Hill Drive Away Assist
Authors: Ramani Sudha , Ramani Sriram , Balasubramaniam Ramthilak
Published: November 2023

This paper describes a patented, standalone, intelligent Hill Drive Away Assist (HDAA) system, comprising of an electro-mechanical unit, to overcome the hurdles faced by the driver while starting the vehicle on a gradient. This system can be added as an additional feature in vehicles which have Manual or Automatic Transmission and are equipped with or without ABS (Antilock Braking System). The developed system is available as Hill Start Assist (HSA) feature in vehicles with Electronic Stability Control (ESC). This HSA functionality is achieved through Drive Away Release (DAR) feature in vehicles equipped with Electric Park Brake (EPB). In ABS only vehicles, this feature cannot be achieved with the existing hardware and software. This HDAA can be implemented as a stand-alone system in vehicles without ESC / EPB, thereby reducing the cost of the vehicle while providing the Hill Start feature. The HDAA is a driver friendly system, which aids the driver while trying to start a vehicle while on a gradient. This development is aimed at providing an assisting feature with the inputs from a g-sensor and other signals available in a vehicle. An algorithm is developed to identify the conditions in which the driver may require assistance to start the vehicle on a gradient. When the vehicle is moving on a gradient, un-coordinated behaviour of the brake, the clutch and the throttle will result in unintended rolling of the vehicle. To avoid this roll, the developed mechanism, added to the brake system, aids the driver by holding the brake pressure for a certain duration, while the driver shifts the foot from brake pedal to accelerator pedal in order to move the vehicle. Considering that ESC is yet to be mandated in Indian sub-continent, this system finds purpose across all vehicle categories.
Shim Bond Coverage Analysis Using Artificial Intelligence

Published: November 2023

Shim bond coverage analysis is a common practice in brake and pad manufacturing during brake pad development. This analysis is used to assess the quality of a shim bond and quantify it in case of any quality or de-bond issues during production and warranty returns. Currently, the analysis is carried out manually in the industry using a 1:1 template printed on tracing paper, which is placed on the deboned shim to identify bad bonded regions. The bond coverage is then calculated manually based on the data obtained from the template, which is a time-consuming process taking around 15 minutes per pad/shim analysis. To minimize manual work and increase accuracy, artificial intelligence is being used to estimate the shim bonding quality and coverage. The idea is to feed the deboned shim and pad picture to the model and predict the following:

Whether the bond coverage is good or bad.

Identify the good/bad and unnecessary regions on the shim/pad for bond coverage analysis.

Finally, provide a bond coverage percentage with a pass/fail criterion.

The training dataset was prepared with good and bad coverage information, and a convolutional neural network model was selected to predict the bond coverage. This paper discusses in detail how the model was trained and deployed to analyze shim bond coverage using visual AI.
Teachers’ Experiences of Teaching the Financial Literacy Component to Enhance Learner Performance in Economic and Management Sciences

Published: November 2023

A few studies have been conducted to understand how secondary school teachers made sense of quality teaching and learning and assessment in general, and particularly in the financial literacy component of Economic and Management Sciences (EMS), a subject outlined in the South African Curriculum Assessment Policy Statement (CAPS). Learner performance in the financial literacy component of Economic and Management Sciences (EMS) has been poor, hence the reason for exploring the experiences of teachers teaching the financial literacy component. The study adopted an exploratory case study design qualitative approach within an interpretivist paradigm. Data were collected through semi-structured interviews with teachers, departmental heads and Subject Advisors considered experts in teaching, in addition to classroom observation. The collected data were analysed by means of thematic analysis. The study findings revealed that many factors influence the teaching of the financial literacy component of EMS. It was recommended if these factors were addressed it could enhance learner performance. In addition, the notional hours allocated to EMS should be increased and it is suggested that projects and case studies should be done away with as forms of assessment as they do not give a true reflection of learner performance. Learners should only be assessed with controlled tests and examinations so that a true picture of their performance could be determined, and proper intervention strategies mapped out.

Studies have shown that self-efficacy is the belief in one's ability to complete a task or achieve a goal, and that this belief can have a significant impact on teaching methods and learning outcomes. Yet, in the context of South Africa, despite the promotion of indigenous languages in Foundation Phase (FP) classrooms, learners continue to struggle on account of low teacher self-efficacy. Underpinned by Bandura’s social cognitive theory, this study used a literature review methodology to explore the self-efficacy-related challenges confronting FP teachers in assessing learners using their indigenous languages. The study also examined the strategies that can used to enhance teachers’ self-efficacy. The findings revealed that factors, such as inadequate teacher training, learner mobility, and resource constraints militate against teachers’ beliefs of their ability to equitably assess FP classrooms. The findings also revealed that possible strategies to enhance FP teachers’ self-efficacy could include making use of role-modelling, improving working conditions, and encouraging continuous professional development and training of in-service teachers, among other steps to be taken. Some of the study’s recommendations include rolling out targeted training and support programmes for FP teachers, aligning FP learner assessment instruments with the diverse linguistic and cultural backgrounds of the learners, and tailoring collaboration between schools and local communities for the benefit of the learners.
Mathematical modelling of terrorists re-cycle induced with backward bifurcation

Published: November 2023

In this work, we formulate a deterministic mathematical model that aims at controlling and preventing terrorism in a population. The model incorporates the prevention of the spread of terrorists in the population by imprisoning individuals caught in the act and allows for natural repentance from terrorism. The main aim of the study is to assess the effect of re-cycling terrorists on the bifurcation phenomena of the model. The model exhibits a backward bifurcation phenomenon. These may have serious implications for the design of intervention programs aiming at eradicating the menace of terrorism. When the values of the scaling factor of the re-cycling rate change from 0 to 1, the bifurcation changes from backward to forward. One or more stable endemic equilibria coexist alongside the stable terrorists-free equilibrium (TFE). It is further demonstrated that the recycling of terrorists who have repented from the terrorism act is what triggers the backward bifurcation cycle. This conclusion is important because it shows that eliminating terrorists from the population is no longer dependent on the old precondition of the basic reproduction number being less than one. The parameter of recycling is deleted, and the model is examined, to determine the reason why this model exhibits a backward bifurcation phenomenon. By taking into account the importance of the original model, this was made achievable. When the terrorists aren’t recycled, the second model will demonstrate a forward bifurcation, according to an analysis of the second model’s coefficient of bifurcation, which is negative.
De abandonos y circulación de niñas:
Authors: Sidy Bettina
Published: November 2023

Analizaremos las formas que fueron adquiriendo los vínculos sociales y filiales en relación con la circulación de menores, particularmente mujeres, en el Río de la Plata durante el periodo tardo colonial. Observaremos cuestiones como: los derechos y las obligaciones implicados en la relación, el peso de las cargas laborales en cada caso y los márgenes de violencia que se ejercieron, especialmente cuando la sexualidad de las menores estuvo directamente implicada en los procesos en cuestión. Para ello analizaremos una serie de procesos judiciales dados en la ciudad de Buenos Aires, en los que se dirimía la potestad sobre el destino de niñas, para explorar diversas conformaciones familiares, así como las trayectorias de las menores involucradas. En este sentido, este trabajo representa un intento por reflexionar en torno a las consecuencias de la circulación de menores en la constitución de los entramados sociofamiliares y en las experiencias vitales de aquellos involucrados.
Bolívar, San Martín y “el pobre” Mitre:
Authors: Amorebieta y Vera María Laura
Published: November 2023

Este artículo tiene como objetivo reconstruir y examinar los contenidos y propósitos que caracterizaron las intervenciones del escritor venezolano Rufino Blanco Fombona y de diversos intelectuales argentinos a lo largo del debate surgido en la revista Hispania entre abril y noviembre de 1913, prestando especial atención a su dimensión textual y a las circunstancias históricas en que se produjo el mismo. En última instancia, se analizan las tensiones suscitadas en torno a las interpretaciones que aquellos actores trazaron sobre Bolívar, San Martín y la revolución de independencia, relacionándolas, a su vez, con los empeños de los primeros por consagrar determinados imaginarios nacionales y continentales, así como por contribuir a la realización o confirmación de ciertos proyectos político-ideológicos.
diputados novohispanos y centroamericanos en las cortes del trienio:
Authors: Chust Manuel
Published: November 2023

En las dos primeras legislaturas de las Cortes durante el Trienio Liberal, los diputados americanos, especialmente los novohispanos y centroamericanos, pusieron de manifiesto la necesidad de desarrollar los artículos constitucionales en lo que respectaba al poder provincial. De esta forma, en un minucioso plan, propusieron y consiguieron que las intendencias se transformaran en provincias, aumentando con ello el número de diputaciones provinciales, verdadero eje central del autonomismo americano y de la descentralización que quería conseguir del nuevo estado liberal doceañista. Sin embargo, encontraron la oposición de la mayor parte de la representación peninsular que se mantuvo en parámetros centralistas.
