ДВУСТВОРЧАТЫЙ СУБМЕНТАЛЬНЫЙ ЛОСКУТ ПРИ РЕКОНСТРУКЦИИ ПОЛНОСЛОЙНЫХ ДЕФЕКТОВ ЧЕЛЮСТНО-ЛИЦЕВОЙ ОБЛАСТИ ПОСЛЕ РАДИКАЛЬНОГО УДАЛЕНИЯ ОПУХОЛЕЙ. КЛИНИЧЕСКИЙ СЛУЧАЙ
Authors: К.Н. Амиралиев
Published: October 2024

Реконструкция полнослойных дефектов челюстно-лицевой области является сложной задачей, поскольку предусматривает формирование внутренней и наружной выстилок дефекта. Для этого необходимы или два разных лоскута или двустворчатый регионарный или свободный лоскут. При использовании свободных трансплантатов пациенты могут не переносить длительную операцию из-за преклонного возраста или сопутствующих заболеваний. В статье приведены результаты применения двустворчатого субментального лоскута для восстановления, как кожи, так и слизистой оболочки дефекта. Операция проста, а время ее намного короче, чем при восстановлении свободным трансплантатом. Такое модифицированное использование субментального лоскута упрощает реконструкции сложного оро-лицевого дефекта.

Reconstruction of full-layer defects of the maxillofacial region is a difficult task, since it involves the formation of internal and external lining of the defect. This requires either two different flaps or a double layered regional flap or a free graft. When using free grafts, patients may not be able to tolerate a long-term operation due to old age or concomitant diseases. The article presents the results of using of bipaddled submental flap to restore both the skin and the mucous membrane of the defect. The operation is simple, and its time is much shorter than free flap reconstruction. This modified use of the submental flap simplifies the reconstruction of a complex oro-facial defect.

AIMS: Metformin is the main drug used in the treatment of type 2 diabetes mellitus, and the most widely prescribed oral antihyperglycemic medication. Its mechanism of action is still not completely understood and research into new uses for the compound is still ongoing, with one possible novel application of the medication being to combat aging on both the cellular and the macroscopic level. The aim of the study is to evaluate the current state of knowledge on metformin’s potential as a lifespan-extending and anti-senescence drug, present evidence on the matter and assess possible lanes of further study into such effects. METHODS: The literature review was performed using Internet research paper databases (PubMed, Google Scholar, Medline), using articles available in English. RESULTS: Multiple papers suggest tentative support for the notion that metformin may contribute to slowing cellular senescence, as well as to extending the human lifespan. Theoretical knowledge exists that shows possible routes of action of metformin in this regard. CONCLUSIONS: There is ample evidence in the literature for metformin’s possible effects as an anti-aging drug. Numerous cellular pathways by which it could exert lifespan-extending effects have been elucidated, and in vivo studies on some non-human animals have shown a measurable decrease in their production of aging markers, as well as an increase in the lifespan. Studies on diabetic patients have also demonstrated a significant reduction in all-cause mortality in that particular group. However, there is a lack of data and a need for more research that would investigate metformin’s potential as a universal anti-senescence agent more directly. Two large-scale studies (MILES and TAME) in the area are currently underway.

Defining the sequence and methods of revascularization in patients with multifocal atherosclerosis should be associated with a minimal risk of adverse events and identification of predictors of adverse outcomes of operations, which is of great importance for improving the results of surgical treatment. We present a clinical case of successful treatment of a patient with multifocal atherosclerosis. The case included atherosclerotic disease of the left subclavian artery with complete steal syndrome of the brachiocephalic arteries, arteries of the lower limbs and arteries of the heart. It is shown that, when choosing a method for treating multifocal atherosclerosis, treatment should begin with preserving and restoring blood supply to the brain, and followed by restoring blood supply to other body parts.

Published: October 2024

In recent times, the investigation and development of multifunctional textiles have become a necessity for the textile and apparel industries. Therefore, this paper explores an innovative approach to enhancing the functional properties of cotton (cellulosic) fabric by integrating advanced technologies to impart oleophobic/hydrophobic, flame-retardant, and antibacterial characteristics. The methodology involves systematically applying chemical treatments utilizing a layer-by-layer finishing technique to achieve the desired multifunctionality in cotton fabric. Silver nanoparticles and a phosphorus-nitrogen-based synergistic flame-retarding agent were employed to finish the fabric. Performance testing encompasses evaluating bacterial reduction, contact angle measurements, water absorption properties, flame-retardant capabilities, and Limiting Oxygen Index (LOI). Characterization techniques such as FTIR, SEM, and EDX analysis, were carried out to assess structural and chemical modifications of the material. The results illustrate a notable transformation of the cellulosic fabric, showcasing enhanced resistance to bacterial attack, improved stain resistance, and heightened flame-retardant performance, without compromising its color indices and air permeability. The fabric retains these multifunctional attributes even after 20 cycles of laundering, which confers durability. The implications of this research extend the application of conventional cotton fabric in diverse sectors, including apparel, home furnishings, and industrial textiles.

Separation membranes have gained attention as promising options for water and wastewater treatment due to their financial sustainability, and eco-friendliness. However, practical challenges have limited their application in water separation. To overcome these limitations, inorganic-organic hybrid membranes have been developed in this study. The present work deals with two attractive aspects: (i) economical, through the valorization of a local clay (Algerian kaolin), and (ii) environmental, which is based on the membrane selectivity for metal ions. The principal objective of this work is the development of enhanced nanocomposite membranes. It is achieved with low costs, based on cellulose triacetate (CTA) as a polymeric matrix modified by the addition of a lamellar filler, i.e. yellow clay obtained from Jijel, located in the east of Algeria, and plasticized by dioctyl phthalate (DOP). A further objective of this paper was the treatment of wastewater polluted by lead (Pb2+) and cadmium (Cd2+). The prepared membranes were characterized by various characterization techniques, including scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy and thermogravimetric analysis (TGA).
All synthetized membranes had an amorphous structure, with homogeneous pore morphology and distribution. Moreover, the presence of nanocomposite clay showed effective integration into the membrane matrix and led to a significant improvement in thermal resistance. These membranes were applied to treat a synthetic aqueous solution contaminated with heavy metals, namely Pb2+ and Cd2+. The results revealed a rejection rate higher than 50%, suggesting the potential effectiveness of a stable and environmentally sustainable polymer inclusion membrane system for water purification.

O objetivo deste trabalho foi mapear a distribuição das variáveis dendrométricas e definir Unidades de Manejo em plantios comerciais de teca, por meio da krigagem com deriva externa, considerando os atributos químicos do solo. Para isso, o presente estudo foi conduzido em plantio comercial de teca situado no município de Nossa Senhora do Livramento, estado de Mato Grosso - Brasil, constituído por povoamento seminal implantado no ano de 1999, perfazendo o total de 223,16 hectares de efetivo plantio. Os dados foram coletados em 46 unidades amostrais, nas quais foram também coletadas as amostras de solo para caracterização química no 2º, 9º e 17º ano. Apesar da possibilidade de definir as Unidades de Manejo utilizando qualquer variável dendrométrica, o presente trabalho buscou estabelecer as Unidades de Manejo em função do produto florestal desejado, ou seja, do volume (V). As Unidades de Manejo para teca podem ser aplicadas no estudo da relação entre o volume (V) e os atributos químicos do solo (potássio trocável – K+, cálcio trocável – Ca2+ e Alumínio trocável Al3+) para os anos de 2008 e 2016. A possibilidade de estabelecer relações espaciais entre o desenvolvimento da teca e os atributos químicos do solo permite a prescrição de intervenções silviculturais precisas e direcionadas para as diferentes condições edáficas, visando a maximização da produção ao longo da rotação da cultura. Portanto, a definição das Unidades de Manejo é uma importante ferramenta de suporte à decisão quando o objetivo é definir a prática silvicultural a ser adotada para cada Unidade de Manejo.

O estudo elenca os principais obstáculos que afetam o lançamento de notas fiscais, e causam atraso nos pagamentos das duplicatas de fornecedores contribuintes de impostos, e o recolhimento deles pelo tomador do serviço, a nível de mudar o faturamento da empresa. O estudo traz como tema, despesas geradas por gargalo durante retenção automática de imposto no lançamento de nota fiscal, estudo realizado na empresa Krindges Industrial S/A situada no sudoeste do Paraná. E como pergunta norteadora, indagou se os atrasos no lançamento de notas fiscais em tempo hábil, impactam nos resultados financeiros e geram atrasos nas retenções e envio dos impostos a Receita Federal? Para que houvesse coerência e desenvolvimento de uma forma ordenada, o estudo baseou-se em um objetivos geral que foi verificar se os atrasos em lançamento de notas fiscais em tempo hábil, impactam nos resultados financeiros e geram retenção de impostos na empresa, e para seguir uma linha de raciocínio utilizou-se de três objetivos específicos, levantamento bibliográficos em relação ao tema do estudo, conhecer o sistema contábil e de lançamento in loco, levantamento de dados e tabulação e analise de resultados. E como metodologia, pode-se dizer que se trata de um estudo de caso, bibliográfico e quantitativo. A estudo demonstrou que atrasos no lançamento de notas fiscais causaram prejuízo financeiro à empresa, totalizando R$ 7.350,09 entre 2021 e 2023. Esses custos foram atribuídos principalmente a juros por pagamentos em atraso e ao trabalho extra do setor contábil e TI para corrigir as falhas. Embora a apresentação pareça pequena para uma empresa SA de lucro real, este valor poderia ter sido direcionado para investimentos estratégicos, gerando um retorno financeiro maior ou melhorando a produção.
Introduction

Why all the fuss about economic inequality? Why does economic inequality matter? Is it just a political theme used to support (or win over) the have-nots? Or, at the very extreme, is it driven by socialists whose goal is to establish a utopia of a supposed ‘equal society’, eventually resulting in a pure communist state? Or is it, at the fundamental level, simply a (serious) threat to economic sustainability and social stability? Yes, inequality does matter. The high levels of poverty and inequality in the world and South Africa justify that these related challenges matter and require continuous analysis, debate, reflection, and discussion. Poverty and its close relation to inequality, the likely increase in conflict and civil war, and the search for social justice need more inquiry into the complexity of inequality’s relationship with other economic variables. In this book, which targets the general public, policymakers, and anyone interested in inequality, the following essays will reflect on different aspects of economic inequality in South Africa, specifically focusing on the period after 1994. The chapters focus on the following topics: how to measure inequality, wealth inequality, wage inequalities, land distribution, access to banking services, inequality in service delivery, socioeconomic inequalities in health, and inequality in education. The final chapters focus on the informal sector, the consideration of a universal basic income grant, and economic inclusivity as some remedies for inequality in South Africa.
Service Delivery Inequality
Authors: Motsitsi Constance
Published: October 2024

Service delivery is the fundamental responsibility of governments all over the world; moreover, the provision of public services has a direct impact on people’s lives and thus enhances their wellbeing. Service delivery and inequality have always been a central focus in South Africa, pre-democracy and post-democracy. In the last 30 years, South African public service delivery has gone through transformation systems, all aimed at enhancing equality in the provisioning of service delivery. However, 30 years later, public service delivery remains utterly poor and unequal among the citizens of South Africa. Nnadozie (2013) is of the opinion that the “current socioeconomic inequalities in service delivery are the effects of the apartheid regime,” which unfortunately continue to haunt the South African service delivery system.
Education and Inequality
Authors: Duvenhage Cecile , Keyser Nico
Published: October 2024

South Africa is known as one of the countries with the most income inequality globally.1 South Africa’s inequality can be attributed to an intriguing relationship between inequalities in access to education, health, income, employment, and living conditions, where many citizens are living in poverty. The decline in South Africa’s economic wellbeing is evident from the ever-increasing unemployment rate, lower living standards, rising poverty levels, inequality, and a sense of hopelessness. This chapter reflects on the opportunity of access to quality education in South Africa and its relevance to inequality. South Africa’s economic growth rate varied between a low of -1.5% per annum in 2009 (after the subprime crisis) and a high of 5.6% in 2006. An average economic growth rate of 2.98% was recorded for South Africa from 1994 to 2015, with a continuing downward trend until 2022. Unemployment has, since 1994, increased from 20% (1994) to 25.3% (2015) and 29.2% (2020),2 indicating an upward trend (see Figure 1).
Income Inequality, Employment, and the Informal Sector
Authors: Fourie Frederick CvN
Published: October 2024

The most critical social and economic ills of South Africa are often listed as a triad: unemployment, poverty, and inequality. These phenomena and how they are defined and measured are dissimilar, and often analysed and studied separately.1 However, in essence, they measure and capture the dimensions of the same phenomenon: the critical challenges of a developing country. In a post-apartheid South Africa 30 years after 1994, these challenges remain intense and unrelenting – and sometimes overpowering, as witnessed in high and increasing rates of unemployment and persistent high inequality.
The Case for a ‘Workable’ Basic Income Grant for Addressing Income Inequality

Can a basic income grant (BIG) reduce poverty and inequality in South Africa? In 1967, Martin Luther King said that guaranteed income is the most straightforward approach to abolish poverty. Nearly six decades later, the South African government is still grappling with the implementation of a universal basic income grant for the millions of destitute South Africans.

В статье рассматривается задача свободного колебания упругих изотропных пластин в форме произвольного треугольника с комбинациями граничных условий по сторонам «жесткое защемление - шарнирная опора». Для определения значения основной частоты колебаний пластин предлагается использовать геометрический метод профессора А.В. Коробко: метод интерполяции по коэффициенту формы, с использованием при этом в качестве альтернативного геометрического аргумента известных из теории конформных отображений геометрически определяемых величин – конформных радиусов. Как показали проведённые исследования, такая замена аргумента позволяет значительно повысить точность метода. Приводится числовой пример вычислений. Указываются преимущества применения данного метода, перспективы решения смежных задач, отличие от известного метода конформных отображений. Рассмотренный алгоритм был реализован в программе для ЭВМ.

Определение предельно допустимой высоты сечения верхнего пояса комбинированной упруго-податливой конструкции
Authors: А.В. Чесноков , В.В. Михайлов
Published: October 2024

Постановка цели. Развитие комбинированных упруго-податливых строительных конструкций, приобретающих эксплуатационную форму за счет натяжения высокопрочных затяжек и деформирования гибких элементов верхнего пояса в упругой стадии, способствует снижению транспортных расходов, а также упрощению и удешевлению монтажных работ. Вместе с тем упруго-податливые конструкции отличаются сложным поведением на этапе трансформации в эксплуатационную форму, а определение их допустимых параметров является важной задачей. Целью настоящей работы является разработка методики нахождения предельно допустимой высоты сечения верхнего пояса упруго-податливой конструкции из условий обеспечения прочности и устойчивости при трансформации в эксплуатационную форму. Результаты. Нормальное напряжение в верхнем поясе и критическая сила выражены в зависимости от отношения площади поперечного сечения к моменту инерции, а также от относительного усилия в затяжке нижнего пояса, которое находится из граничных условий, налагаемых на форму верхнего пояса в эксплуатационном положении. Выяснено, что увеличение жесткости на изгиб верхнего пояса влечет рост напряжений на стадии трансформации конструкции. Для прямоугольных трубчатых элементов получены условия обеспечения прочности и устойчивости, позволяющие при заданной толщине стенки и относительной ширине определить предельно допустимую высоту сечения. Выводы. Полученные результаты могут быть использованы для определения области эффективного применения упруго-податливых конструкций в части назначения предельно допустимых пролетов и выбора материала верхнего пояса. Результаты работы способствуют развитию методики расчета и проектирования комбинированных строительных конструкций, эффективных для применения на отдаленных и труднодоступных территориях.

Published: October 2024

Plant-derived products have played an important role in the development of several clinically useful anticancer agents. Several cancer treatments have been widely used, including surgery, chemotherapy, and radiotherapy. However, no selective cancer therapies exist that can eliminate cancer cells while preserving healthy cells unharmed. This study aims to determine the antimitotic activity of Hibiscus rosa-sinensis leaf extract in the early in-vitro development of sea urchin Tripneustes gratilla embryo.

The Hibiscus rosa-sinensis leaves were extracted using ethanol into four different concentrations (0.5%, 1.0%, 1.5%, 2.0%). A Sea urchin bioassay was then performed to determine its antimitotic activity against the Tripneustes gratilla embryo. Phytochemical confirmatory tests were also done to confirm the presence of bioactive compounds. The results of the study showed that Hibiscus rosa-sinensis leaf extracts contained alkaloids, flavonoids, tannins, and saponins.

The Sea Urchin Bioassay reveals that the various leaf extract concentrations (0.5%, 1.0%, 1.5%, 2.0%) inhibited antimitotic activity against the early cell development of sea urchin embryo as it had a slower rate of mitotic activity as compared to the negative control. Moreover, the higher concentration of leaf extract 1.5% and 2.0% revealed to have greater antimitotic activity similar to that of the positive control colchicine as data showed it had the least number of embryos developed. This implies that the antimitotic activity of Hibiscus rosa-sinensis leaf extracts is concentration-dependent.

An ANOVA test showed that there are significant differences between the various leaf concentrations and control groups in the early cell development of sea urchin embryos in minute intervals.

Effective Propagation Methods: Vegetative Propagation of Some Fruit Tree Species and Endangered Tree Species
Authors: - Bhim Sahu , - Smitha Pankaj , - Jyoti Kumar , - Geeta Mahto
Published: October 2024

Vegetative propagation is a method used for plant reproduction. This process is commonly used in fruit plant propagation for several reasons, including the maintenance of desirable traits, rapid multiplication of plants, and ensuring genetic uniformity. Vegetative propagation is widely used in agriculture, horticulture, and landscaping for various purposes, including crop production, ornamental plant cultivation, and conservation of rare or endangered species. Various vegetative propagation techniques exploit the ability of plants to regenerate specialized tissues and structures. Commercially valuable crops, such as seedless fruits (e.g., seedless grapes and bananas) and sterile ornamental plants, are propagated through vegetative means because they do not produce variable seeds. Vegetative propagation enables the continued production of these varieties. The mass replication of commercially important fruit species depends on high-quality and consistent planting materials for economic gains. The lengthy gestation period of fruit crops also necessitates high-quality planting material to avoid any economic loss in later stages. The success rate of vegetative propagation methods depends on factors such as plant species, environmental conditions, and propagator skill. This study investigated various vegetative propagation techniques for mango, lychee, guava, jamun, lemon, salai, and Rudraksha trees. The results demonstrate the effectiveness of different methods such as stem cutting, air layering, and grafting, ensuring rapid multiplication, genetic uniformity, and preservation of desirable traits.
The Evolution and Challenges of Women Legislators in Bihar: A Historical Analysis
Authors: - Habibul Rahman Ansari
Published: October 2024

This paper explores the role of women legislators in Bihar, India, from the first general election in 1952 to the present. It examines how women’s participation in the state assembly has changed over time and the challenges they have faced. In the early years, women had very limited representation in Bihar’s politics, mainly due to patriarchal norms, caste discrimination, and a lack of political opportunities. The 73rd and 74th Constitutional Amendments in the 1990s, which introduced reservations for women in local governance, helped increase their participation, particularly at the grassroots level. However, at the state level, progress has been slow. As of 2020, women held only 10.7% of seats in the Bihar Legislative Assembly. Despite these challenges, women legislators have made important contributions, especially in areas like education, healthcare, and social welfare. This study also highlights barriers such as caste and gender bias, financial limitations, and a lack of support from political parties. Finally, the paper suggests policy changes, such as stronger reservation enforcement and more support for women candidates, to improve women’s representation in Bihar.

The Quest for Identity and Self-Discovery: A Study of Existential Crisis in Anuradha Roy’s The Folded Earth
Authors: - Swati Vaishya
Published: October 2024

The main objective of this term paper is to analyze the theme of existential crisis in Anuradha Roy’s famous novel The Folded Earth. The term “existential crisis” refers to facing the crisis of one's existence. This mainly talks about how people view themselves, as well as their meaning and goals in life. When people feel unsure about their purpose, options, or freedom in life, they are experiencing an existential crisis. Many persons who experience existential anxiety believe that life is meaningless and that there is no purpose to it. Confused thoughts concerning one's sense of identity might also result from an existential crisis. Some of the greatest existential philosophers and writers are Friedrick Nitzsche, Hegel, Soren Kierkegaard, Martin Heidegger, Jean-Paul Sartre, Karl Marx, Franz Kafka, Fyodor Dostoyevsky, Albert Camus and Simon de Beauvoir, etc. This novel The Folded Earth is written by Roy, a recent Sahitya Akademi Award winner, which traces the story of a young woman Maya who creates a new life for herself in the foothills of the Himalayas. It deals with how she becomes alone in her life and questions her existence in this world. It is a time of internal turmoil for Maya when she struggles with self-identity, meaning, and purpose in life. She fights with many traumatic experiences like alienation, anxiety, depression, identity crisis, etc. Then, after leaving her tragedy behind, he decides to go for exploring a new life. Thus, this novel explores the "new woman identity" in modern-day society. The theme of this novel is based on political and religious conflicts in society, patriarchal suppression, inequality, the psychological instincts of a person, identity crisis, and the desire for a new peaceful life. Although the novel has various themes the effect of existential crisis is dominant over the novel.
Julius Caesar's Rise to Power
Authors: - Ashya Agarwal
Published: October 2024

Beginning in 69 BCE. Caesar rose in the Roman cursus honorum,2 first as quaestor then to the rank of aedile and subsequently pontifex maximus (one in-charge of state religion) in 63 BCE marking his beginning of ascendency of power.3 Historian Robert C.L. Holmes says Caesar lived through the barbaric invasion of Rome undertaken by General Sulla forcing him to escape and ultimately join the Roman forces with the North Europeans in the Gallic Region of modern day France.4 His command during the successful repression of the invading Helvetii tribe, pressured the existing senate of Rome into acknowledging his leadership and military prowess.5 Historian Plutarch states that along with his military acumen, the political backing of the financially affluent Marcus Licinius Crassus and the then consul of Rome, general Pompey allowed him to gain a strong foothold in the Roman senate system.6 Researcher Phillips states that Caesar’s mighty conquest of Gaul (58-50 BC), was followed by his refusal to disband his war legions against what contemporary practice suggested, thus opposing the senate; breeding a civil war in ancient Rome which became the epicentre of his renowned military exploits.7 Caesar consequently attained the highest position in Rome, that of consul, in 59 BCE with the guarantee of being given a province to rule, by the senate.8 These military achievements allowed Caesar to create and enforce his influence not only on the populace but paved the way for convenient eradication of his competitors. “He (Caesar) played on Pompey's frailties cleverly and offered to resign his command.”9 Apprehensive of the resulting complications and the threat to stability of the administration, “...the Senate dared not entertain such an offer.”10 The subsequent win against Pompey in 49-45 BCE made him the most powerful man in Rome and thus, the senate had to accept his motion of being made ‘Dictator’ followed shortly by ‘Dictator for Life.’11 He reinvented the concept of dictatorship which was previously a set period of time to resemble the autocratic regime now known to the modern public, as the sole ruler for as long as one lives.12
