Шляхом мікромеханічного осереднення на циліндричній представницькій комірці вдалося послідовними аналітичними методами побудувати криву текучості для ізотропного пористого матеріалу. Отримана реологічна модель пластичності пористого матеріалу описує явища різноопірності розтягу-стиску та дилатансії. Вищезгадані ефекти зокрема характерні для пошкоджених або сипучих матеріалів. Також ця крива текучості відображає деякі інші, підтверджені експериментом, специфічні особливості пластичної реакції порошків та порошкових заготовок з металів і кераміки. Зокрема такі особливості пластичної реакції, які неможливо на деяких ділянках кривої текучості узгодити з асоційованим законом пластичної течії.

Background: The most prevalent joint condition and leading contributor to disability is osteoarthritis (OA), resulting in a significant socio-economic impact. It occurs due to an imbalance of pro-inflammatory and anti-inflammatory mediators, influencing anabolic and catabolic activities. This study aims to determine the effect of activated growth factor (AGF) on alpha-SMA levels.
Methods: This research is an in vivo post-test-only control group experimental study conducted at the Eureka Research Laboratory. Thirty male Wistar rats were divided into five treatment groups: normal control group, negative control group, AGF I group (TGF-β 100 pg/mL), AGF II group (TGF-β 1000 pg/mL), and AGF III group (TGF-β 10,000 pg/mL). AGF was obtained from rat blood intravenously and centrifuged at a predetermined speed. Growth factor activation was performed by adding 10% CaCl2, and then TGF-β levels were measured. All groups of rats were acclimatized for 7 days. After that, osteoarthritis was induced with intra-articular injection of monoiodoacetate (MIA) 4.8 mg/60μL in all groups of rats except the normal control group. Next, rats were given treatment according to the group for 21 days. On the 21st day, rats were euthanized, and alpha-SMA levels were measured using the sandwich method ELISA kit.
Results: Sequentially, the mean Alpha-SMA levels for each group in pg/mL were: 91.495 ± 2.36; 10.682 ± 1.09; 30.502 ± 2.00; 52.892 ± 1.29; and 76.180 ± 2.65. In the AGF group, there was an increase in alpha-SMA levels directly proportional to the dose of TGF-β injected.
Conclusion: AGF has an effect on increasing alpha-SMA levels in the joints of rats with a model of osteoarthritis.

The research aims to find out the Communication Strategy of the Youth Information and Counseling Center (PIK R) Merpati on the Generation Planning Program at SMKN 3 Bengkulu City.The method used in this research is qualitative research. This research uses Everett M. Rogers' innovation diffusion communication model which consists of: The results showed that first, PIK R Merpati SMKN 3 Bengkulu City provided knowledge on the importance of maintaining adolescent reproductive health only by conducting direct socialization during student orientation (MOS) for students of SMKN 3 Bengkulu City, namely through regular meetings to PIK R Merpati members. Furthermore, knowledge is also carried out by indirect socialization through the Instagram account @pikrmerpatismkn3. Second, the persuasion of PIK R Merpati trainers is by giving appreciation to students in the form of gifts for being active in the education of maintaining adolescent reproductive health. The socialization media used by PIK R Merpati is by disseminating videos and pamphlets on social media Instagram account @pikrmerpatismkn3 such as animations, and cartoons. Third, the decision of students of SMKN 3 Bengkulu City is that the majority accept it while only one student rejects it. Fourth, Confirmation of students of SMKN 3 Bengkulu City accepts well the education of maintaining adolescent reproductive health on the grounds that they consider the information important. While students who reject education because they do not get permission from their parents. The Communication Strategy of the Merpati Youth Information and Counseling Center (PIK R) on the Generasi Berencana Program at SMKN 3 Bengkulu City has been running well but has not been fully maximized because the number of followers of PIK R Merpati participants has not shown a significant increase in the number of followers of PIK R activities each year, because the communication strategy focuses more on face-to-face socialization while socialization through media only Instagram accounts should involve more social media as a medium of education.
Electron Heating by Magnetic Pumping and Whistler-mode Waves

Published: February 2024

Abstract
The investigation of mechanisms responsible for the heating of cold solar wind electrons around the Earth’s bow shock is an important problem in heliospheric plasma physics because such heating is vitally required to run the shock drift acceleration at the bow shock. The prospective mechanism for electron heating is magnetic pumping, which considers electron adiabatic (compressional) heating by ultralow-frequency waves and simultaneous scattering by high-frequency fluctuations. Existing models of magnetic pumping have operated with external sources of such fluctuations. In this study, we generalize these models by introducing the self-consistent electron scattering by whistler-mode waves generated due to the anisotropic electron heating process. We consider an electron population captured within a magnetic trap created by ultralow-frequency waves. Periodical adiabatic heating and cooling of this population drives the generation of whistler-mode waves scattering electrons in the pitch-angle space. The combination of adiabatic heating and whistler-driven scattering provides electron acceleration and the formation of a suprathermal electron population that can further participate in the shock drift acceleration.
How food insecurity experience among older adults can provide evidence for an innovative, system-led and culturally-sound social work practice interventions in a communal Ghana
Authors: Asamoah Brilliant 
Published: February 2024

As people grow older and lose capacity to maintain activity in securing food for themselves either because of functional disability or financial incapacity, there should be a meso and or macro support services to ensure food security amongst them. In Ghana, evidence show that most older people report food insecurity, necessitating a need for a reflection on how social work professional (with its core mandate) can innovatively and culturally promote food security for older adults in Ghanaian context. Deploying descriptive qualitative analysis, this study presents the qualitative findings of older adults’ experiences of food insecurity across three regions of Ghana. Overarchingly, the analysis identified three major themes related to food insecurity experience recurrent to all or most of the participants. The themes include 1) sources of food items for older adults; 2) perspective on accessibility to food; 3) finances determining older adults’ food accessibility. Results are discussed in relation to existing literature and social work implications. Social work profession in Ghana can adopt innovative and culturally sound approaches, including ‘nnoboa’ in ensuring food security for older adults. The findings contribute to the evidence base for social work, elaborating the in-depth understanding of the experiences of food insecurity in old age.

The Influence of Virtual Events on Metaverse Commercial Real Estate Values: A Review
Authors: Nesaif Bader Mohammed Rashed Bin 
Published: February 2024

Purpose: This review paper examines the complex relationship between virtual events and the commercial real estate prices in the dynamic Metaverse, which is a network of interconnected virtual communities enabling real-time interactions. Virtual events have emerged as a prominent element of our digital reality, surpassing geographical limitations and reshaping the understanding of interaction and professional connections. This paper aims to explore the intricate interplay among technology, virtual events, and the commercial real estate ecosystem within the Metaverse.
Materials and Methods: It will analyse several case studies, identify emerging trends, and assess the economic ramifications of these dynamics. This observation highlights the capacity of virtual events to influence the real estate environment of the Metaverse, presenting prospects for developers and investors. However, it also underscores the need for comprehensive regulatory frameworks to guarantee equity and long-term viability.
Findings: The increasing recognition of virtual events by corporations and organisations has led to a growing need for appropriate virtual venues inside the Metaverse. Consequently, this surge in demand has directly influenced the worth of virtual commercial real estate. The ongoing development of the Metaverse holds the potential to create a forthcoming reality in which the physical and virtual domains coexist and fundamentally transform our methods of engaging with the surrounding environment.
Implications to Theory, Practice and Policy: Utilise digital twin technology for interactive property replicas, enabling potential buyers to explore properties virtually before visiting. Enhance efficiency and transparency in property transactions by exploring blockchain and smart contracts; leverage the metaverse for collaborative design and conduct virtual training for real estate agents to optimize technology utilisation.

Material and methodsWe used data from the Global Burden of Disease Study 2019 to calculate the incidence rates of and estimated annual percentage changes (EAPCs) in disability-adjusted life-years (DALYs) due to nutritional deficiencies in 204 countries and territories from 1990 to 2019.ResultsDuring this period, the age-standardized incidence rate of nutritional deficiencies remained stable globally (EAPC = –0.05; 95% confidence interval (CI): –0.20 to 0.09) and increased the most in high–middle-sociodemographic-index (SDI) areas. In addition, at the region level, from 1990 to 2019, the age-standardized incidence rate of nutritional deficiencies increased the most in South Asia, whereas at the country level, it increased the most in Czechia (EAPC = 1.81) and Turkey (EAPC = 1.45). Furthermore, from 1990 to 2019, the global age-standardized DALY rates due to nutritional deficiencies decreased (EAPC = –2.91), especially in East Asia, Andean Latin America, and Eastern Sub-Saharan Africa.ConclusionsFrom 1990 to 2019, the age-standardized incidence rate of and DALY rates due to nutritional deficiencies remained high in low–middle- and low-SDI areas, and Southeast Asia, Czechia, and Turkey had the highest levels of nutritional deficiencies.

IntroductionIodine deficiency is a global issue; however, no comparable assessments of the burden of iodine deficiency have been conducted worldwide. Hence, we measured the estimated annual percentage changes (EAPCs) from 1990 to 2019. Our aim was to quantify the geographic differences in the burden of iodine deficiency worldwide.Material and methodsThe Global Burden of Diseases, Injuries, and Risk Factors Study 2019 methodology was employed to investigate the worldwide, regional, and national incidence of iodine deficiency and the accompanying disability-adjusted life years (DALYs).ResultsThe global age-standardized incidence (ASI) and DALY rates of iodine deficiency declined from 1990 to 2019, with an EAPC of –0.44 and –1.35, respectively. Low and low-middle SDI had much higher ASI and DALY rates of iodine deficiency than other SDI regions. At the regional level, the largest growth in the ASI rate of iodine insufficiency from 1990 to 2019 occurred in East Asia, and at the national level, the greatest increases in the ASI rate of iodine deficiency occurred in the Philippines, Pakistan and Nepal. In addition, males had a lower worldwide ASI rate of iodine insufficiency than females did, with the incidence rate peaking in populations aged 20–24.ConclusionsBetween 1990 and 2019, there was a decline in the global ASI and DALY rates of iodine deficiency. However, East Asia, the Philippines, Pakistan and Nepal exhibited the largest increases in the ASI rates of iodine deficiency, demonstrating their significant burden of iodine insufficiency. These regions must therefore be targeted for intervention.

Published: February 2024

Aim: New types of denture teeth using modified acrylic resin that incorporate cross-linking agents and composite resin containing different types of filler have become increasingly common. It has been possible to produce nano-sized filler particles with nanotechnology. However, evidence-based information regarding composition and properties is lacking. The purpose of this study was to evaluate the colour stability of four commercially available denture tooth materials with different chemical structure when subjected to various beverages.
Methods: Conventional acrylic resin, reinforced acrylic resin, microfiller composite resin, and nanofiller composite resin teeth with different brands were used, for a total of four different denture teeth groups. Denture teeth were subjected to four beverages (tea, filtered coffee, cola, and cherry juice) and distilled water as control. The test period of 24 hours appears comparable to approximately 1 month of normal beverage consumption. The test periods used in this study were arranged according to this protocol and 1 week, 1 month, 3 months and 6 months of normal beverage consumptions were simulated. From each group, 10 maxillary first molar denture teeth were immersed in each of the five solutions. The baseline, 1st week, 1st month, 3rd month and 6th month values for colour change of denture teeth were measured.
Results: The differences of each value were calculated by one-way ANOVA statistically. For colour changes (ΔE) there was no significant difference among the specimens immersed in distilled water (Tukey HSD test, p>0.01). The highest colour changes were recorded for the specimens of Integral and Major immersed in cola, whereas for the specimens of Veracia and Orthosit immersed in tea (Tukey HSD test, p

Published: February 2024

Волоконная сетка Брэгга (tbt) волоконные датчики были успешно имплантированы и за последние два десятилетия были признаны пригодными для использования в автомобильной, авиационной, морской промышленности, для наблюдения за конструкциями и подводной разведки нефти. Их использование в интернете, биомедицинских наблюдениях и реабилитационных технологиях является недавней тенденцией. В этой статье обсуждается теоретическое моделирование работы датчиков ТБТ, чтобы перечислить параметры моделирования, которые изначально использовались в моделировании. Фактически, спектр отражения должен быть получен с помощью оптического анализатора спектра, что является дорогостоящим решением. Используя эти параметры, была разработана программа моделирования MatLab для снижения лабораторных затрат и производительности, что дает представление о смоделированном спектре отражения. MatLab позволяет использовать оптическое волокно перед созданием конкретного датчика на основе tbt, поскольку полученные результаты дают четкое представление о конкретных производственных параметрах, при которых производятся датчики. Также на основании полученных результатов можно изучить влияние внешних факторов, таких как деформация, давление и температура, на спектры отражения датчика на основе ТБТ.

Общепринятая в странах ближнего зарубежья система ремонта парка железнодорожного подвижного состава, в том числе и Казахстана, сформировалась с учетом плановой экономики и основана, в основном, на «статистических» принципах, например: неизменная структура эксплуатационного парка железнодорожного подвижного состава, неизменяемые в течение продолжительного времени нормативно-технические и регламентирующие документы по выполнению ремонтных воздействий, а также имеющиеся в наличии неснижаемые материально-технические запасы и неизменяемые эксплуатационные условия. В статье рассмотрены основные показатели железнодорожного транспорта на железных дорогах Казахстана и предложен сравнительный анализ системы технического обслуживания, ремонта и сервисного обслуживания подвижного состава железнодорожного подвижного состава. Выполненные исследования показали, что применение логистического подхода находит все более широкое внедрение на самых различных предприятиях, занимающимися не только железнодорожными перевозками, но и в других отраслях экономики и бизнеса. В статье показано, что обеспечение вагонного парка необходимыми запчастями, в том числе для вагонов новой конструкции, следует осуществлять в рамках согласованных заявок ремонтных предприятий на поставку запасных частей. Заявки формируются исходя из потребности и объемов на основании прогнозов от собственников, выбора ими предприятий с учетом дислокации оперирования вагонов и планирования необходимой номенклатуры на основе логистического подхода.
