Introducing Transformative Plant Biotechnology: Unlocking the Secrets of Grass Stomata: Blue Light Response and the Role of Subsidiary Cells in Guard cell Starch Metabolism
Authors: Dang Trang
Published: November 2023

Stomata are essential for controlling gas exchange and maintaining plant water efficiency. While most angiosperms have kidney-shaped stomata, grasses have unique dumbbell-shaped stomata, which respond faster to environmental changes. It's believed that the presence of two subsidiary cells in grasses enables rapid osmotic adjustments, leading to prompt stomatal closure or opening. This makes investigating the molecular mechanisms underlying the interactions between subsidiary cells and guard cells crucial for enhancing plant adaptation to water-limited environments.

Recent research on Arabidopsis thaliana has revealed that blue light triggers fast stomatal opening kinetics by rapidly degrading starch in guard cell. However, this process hasn't been thoroughly studied in dumbbell-shaped stomata of grasses, and the sugar transportation pathway between guard and subsidiary cells in grass stomata is poorly understood. To bridge these knowledge gaps, our research focuses on examining the metabolic processes of chloroplast starch in C3 grass stomata. Our findings demonstrate that grass stomata respond significantly to blue light independently of leaf photosynthesis, and subsidiary cells in grass stomata play a crucial role in the metabolism of guard cell chloroplast starch in response to blue light. These insights provide new perspectives on the significance of carbohydrates in the superior performance of grass stomata and present exciting research opportunities for exploring the molecular mechanism of guard cell chloroplast starch in dumbbell-shaped stomata.

Findings from the first wave of Covid-19 on the different impacts of lockdown on public health and economic growth
Authors: Kargı Bilal , Coccia Mario , Uçkaç Bekir Cihan
Published: November 2023

This paper examines the impact of different durations of national lockdown measures during the first wave of the COVID-19 pandemic on the public health and economic conditions of nations. Results indicate that a) countries with shorter lockdown periods, approximately 15 days, experience a higher variation of confirmed cases/population (%) compared to countries with longer lockdowns, lasting for over one month; b) countries with shorter lockdown periods experience lower average fatality rates compared to countries with longer lockdown periods, while the variation in fatality rates indicates that countries with longer periods of lockdown achieved a more substantial reduction in fatality rates. Nevertheless, the findings of the study indicate that while longer durations of national lockdowns, implemented as a government response to the COVID-19 pandemic, appear to produce somewhat uncertain outcomes in terms of public health, they exhibit a more substantial adverse effect on a country’s economic growth, resulting in a contraction in gross domestic product growth. Extracting key lessons from this study can prove invaluable in crafting effective public responses for future COVID-19 waves and epidemics that resemble the characteristics of COVID-19.
The Treynor Ratio as a Risk-adjusted Return of Croatian Listed Firms
Authors: Pavic Kramaric Tomislava , Miletic Marko , Pepur Petar
Published: November 2023

Motivated by the importance of determinants of firm performance, especially in terms of risk-adjusted performance that considers underlying risks, this paper explores the effects of firm-specific determinants on risk-adjusted returns such as the Treynor ratio. Specifically, the authors explore whether firm size, capital expenditures, capital intensity, equity ratio, leverage, profitability, listing age, and liquidity affect the performance of Croatian non-financial listed companies that form the CROBEXplus equity index in the period 2014 – 2021. Utilizing dynamic panel analysis, several key deterministic factors of risk-adjusted performance are identified including firm size, capital intensity, equity ratio, leverage, profitability, and listing age. In other words, larger firms tend to experience greater risk adjusted returns than their smaller counterparts as well as firms with higher equity ratios, i.e. those not overly indebted. Results also show that capital intensity, which is viewed as a source of entry barrier, is positively related to risk adjusted-performance which is also true for profitability. Furthermore, companies that have a longer presence in the market in terms of being listed on the stock exchange document enhanced risk-adjusted returns. These findings have significant policy and practical implications.

HUNGARY’S POSITION ON THE RUSSIA-UKRAINE WAR AND ITS IMPLICATIONS FOR COOPERATION IN THE VISEGRAD GROUP
Authors:   Dokuz Eylul University, AKGUL DURAKCAY Fulya
Published: November 2023

Visegrad Group (V4) composed of Hungary, Poland, the Czech Republic and Slovakia is a significant subregional partnership that has influenced the European Union’s policies particularly in the area of migration policies. Although the group does not always speak with one voice in every policy area, Hungary became particularly estranged from the V4 due to its differing position on the Russia-Ukraine war. This study analyses the implications of Hungary’s stance on the Russia-Ukraine war for the V4 cooperation. With this aim, it overviews the importance of the V4 in furthering Hungary’s interests, searches for economic and political considerations influencing Hungary’s position on the Russia- Ukraine war, and discusses the diverging positions of the rest of the block on the war with its implications for the V4 cooperation. The study benefits from the analysis of primary sources such as the V4 declarations and official statements, Hungarian presidency programs, Orbán’s statements as well as the news and the secondary research. The study finds out that Hungary endorses the unified EU stance as long as it does not contradict its core interests among which its energy security prevails. Yet, Hungary’s differing position on the war from that of the EU and the V4 by being pro-Russian as a result of being pro-Hungarian stems from its divergent views on security and foreign policy objectives. Although Hungary’s stance on the war has affected the V4 cooperation adversely at the beginning, as there is no clear end to the Russia-Ukraine war soon, Hungary’s partners shifted their attitudes to focus on their shared interests inside the V4 bloc rather than on what separates them.

Authors:   Kırıkkale University, OZEL OZCAN Merve Suna
Published: November 2023

The Eurasian geography is a strategic intersection for great powers which are currently interested in the region. After the collapse of the USSR, the Russian Federation seemed to slow down politically between 1990 and 2000 to regain its lost power and maintain its influence in the region. Geography continues to impact states’ survival and foreign policies in the Eurasian region. After the Cold War, the Shanghai Cooperation Organization became one of the critical organizations in the Eurasian region. The paper discusses the organization’s influence and power in the region’s geopolitical significance. Its methodology will be a comparative literature interpretation on the axis of qualitative data. The study assumes that this region remains a game-changer where great powers focus. The paper also evaluates the latest situation based on regional and global developments.
Geneza post-istine
Authors: Mijović Pavle
Published: November 2023

Cilj rada naslovljenog Geneza post-istine. Politika i znanost je analizirati pojam i fenomen post-istine te ponuditi moguće određenje toga pojma. Metodologija rada temelji se na trima međusobno povezanim momentima koji su povoljno utjecali na nastajanje jednog takvog planetarnog fenomena, a to su politički, znanstveni te filozofski moment. Prvi dio rada donosi generalno određenje fenomena post-istine, isprva na temelju lingvističkih uvida koji nam pomažu da proniknemo u samu esenciju navedene sintagme. Politički kontekst, privilegirano mjesto javne sfere, pokazuje problematičan suodnos istine i politike, koje su često u antitetičkom odnosu. Prvi dio rada odgovara na pitanje o nastanku same sintagme post-istine, koja je uvjetovana društveno-političkim kontekstom. U drugom dijelu rada idemo korak dalje te ukazujemo na činjenicu kako se doba post-istine inspirira na skepsi u, društveno gledano, privilegirani oblik spoznaje, a to je onaj znanstveni. U nekoliko suvremenih primjera skepse u suvremenu znanost (cjepiva, klimatske promjene, ravnozemljaške teze) pokazujemo kako navedene antiznanstvene pozicije povoljno djeluju na generiranje pogleda na svijet nakon-istine. Nije riječ samo o epistemičkoj sumnji nego o jednom sveobuhvatnom momentu skepse koja je i psihološki utemeljena a transponirana je u širu javnu sferu. Zaključna razmatranja u sintetičkoj formi rezimiraju saznanja do kojih smo došli vezano za genezu post-istine.

Posljednja dva poglavlja Knjige Otkrivenja donose nam čuveni prikaz novog grada Jeruzalema. Dok se s jedne strane divimo ljepoti toga prikaza, istodobno smo uistinu i zbunjeni te se pitamo koji bi bio smisao takvog prikaza (usp. Otk 21–22). Naravno, uzimajući u obzir književnu vrstu Knjige Otkrivenja te njezin simboličan govor dolazimo na neki način do mogućeg odgovora o smislu i značenju prikaza novog Jeruzalema u Knjizi Otkrivenja. Međutim, opis novog grada Jeruzalema ipak nas dovodi i pred temeljno pitanje o tome je li prikaz novog grada Jeruzalema u Knjizi Otkrivenja utopija ili realnost? Stoga autor u ovom radu, uzevši u obzir novija istraživanja ove apokaliptičke knjige, nastoji na sveobuhvatan način pristupiti iznalaženju odgovora na pitanje o realitetu prikaza novog grada Jeruzalema u Knjizi Otkrivenja.

Authors: Santos Gesmar Rosa , Farias Ana Lizete , Bronzatto Luiz Augusto
Published: November 2023

A Agenda ONU (Organização das Nações Unidas) 2030 reconhece, no conjunto de seus 17 ODS (Objetivos de Desenvolvimento Sustentável), a presença de conflitos de distintos graus, natureza e tipologia. Seguindo o debate acadêmico, a Agenda considera importante o registro de conflitos e a promoção de ações de mitigação em foros participativos e com amplo diálogo. Neste contexto, o objetivo deste artigo é apresentar distintas concepções, dados e formas de manifestação dos conflitos pela água no cenário internacional e, particularmente, no Brasil. Faz-se também uma reflexão sobre possibilidades de aprimoramentos nos registros com o advento dos ODS. São destacados dados históricos de plataformas, instituições gestoras e outros registros públicos de conflitos pela água. Entre os resultados para o Brasil, destaca-se que os levantamentos são aperiódicos, com metodologias em desenvolvimento e foco no meio rural. Os registros da Comissão Pastoral da Terra (CPT) apontam trajetória de aumento do número e tipos de conflitos pela água no campo, majoritariamente causados por atividades produtivas (mineração, energia e agricultura). Entre as lacunas por parte do Estado, encontra-se a falta de estratégia para registro e monitoramento dos conflitos, com dependência de levantamentos voluntários de organizações sociais e da academia.
Mulheres, água e equidade: uma agenda que faz sentido?
Authors: Santos Gesmar Rosa , Nogueira Daniela Soares , Freitas Diego Antônio França
Published: November 2023

A questão de gênero na Agenda 2030 tem espaços em diversas metas dos Objetivo de Desenvolvimento Sustentável (ODS), incluindo o ODS 6, cujo foco é gestão da água e universalização do saneamento. A Organização das Nações Unidas (ONU) destaca o papel diferenciado de mulheres e meninas no provimento e gestão da água, particularmente em situações de insegurança hídrica por escassez de água ou ineficiência de serviços de saneamento. Nesse sentido, o objetivo deste artigo é destacar convergências, lacunas e oportunidades de promoção da agenda água e mulheres no Brasil, a partir da articulação de políticas públicas nacionais e locais. O tema água e mulheres registra avanços no contexto mais amplo de conquistas por igualdade de espaços, condições de acesso, poder e oportunidades no país, embora esta agenda esteja ainda em construção. No tocante à gestão da água, o artigo apresenta lacunas organizativas e de participação e descontinuidade de orçamentos que dificultam a efetivação das políticas. São necessárias estratégias de incorporação da perspectiva de gênero considerando: i) a internalização dessa agenda na estrutura oficial de gestão e governança das águas; ii) a abertura de espaços participativos em diferentes níveis e instâncias decisórias (comunitário, bacia hidrográfica, governos, empresas e outros); iii) a incorporação do tema nas instituições e foros públicos e privados; iv) a articulação efetiva dos ODS 2, 5 e 6 às leis nacionais para maior inclusão das mulheres na gestão e governança das águas.

Published: November 2023

Apesar da importância dos recursos hídricos para o ser humano, observam-se diversas lacunas na disponibilidade de dados para o suporte às tomadas de decisão na esfera das políticas públicas. Neste contexto, o System of Environmental-Economic Accounting for Water (SEEA-Water) é uma ferramenta auxiliar da gestão e planejamento de recursos hídricos cujo objetivo é a sistematização e padronização de dados hidrológicos e econômicos em um mesmo quadro conceitual. Esse quadro é constituído por tabelas e indicadores que seguem a organização dos Sistemas de Contas Nacionais (SNA), conforme regularmente publicado pelo Instituto Brasileiro de Geografia e Estatística (IBGE). O modelo tem sido adotado com o objetivo de fornecer informações estratégias, de maneira sistematizada e confiável, para apoiar a tomada de decisão frente aos desafios da gestão de recursos hídricos em escala nacional e subnacional. Este artigo apresenta uma discussão sobre a contribuição do SEEA-Water para o planejamento e gestão de recursos hídricos. Além disso, a contribuição do SEEA-Water ao monitoramento dos Objetivos do Desenvolvimento Sustentável (ODS) é apresentada considerando as informações que podem ser obtidas diretamente do SEEA e/ou adaptadas para o ODS 6, ou ainda suporte ao monitoramento das metas e objetivos vinculados. Por fim, apresenta-se uma discussão sobre o caráter amplo de modelos como o SEEA-Water no contexto da política ambiental brasileira e os avanços rumo a integração do capital natural na composição do Produto Interno Bruto do país.

O artigo aborda a metodologia para cálculo dos indicadores adotada pela Organização das Nações Unidas (ONU) para o sexto Objetivo de Desenvolvimento Sustentável (ODS 6: Água potável e saneamento) e resultados para o Brasil. O foco é a meta 6.1 e o indicador 6.1.1, que tratam do abastecimento de água segura para todos. São utilizadas as principais bases de dados disponíveis no Brasil e uma abordagem descritiva e interdisciplinar do tema. Ao apresentar fragilidades nos parâmetros de cálculo e nos dados disponíveis, o texto ressalta a importância de que eles traduzam realidades locais e regionais em sintonia com as leis e os atos regulatórios nacionais. Foram observadas divergências entre os resultados apresentados por entidades responsáveis distintas para o indicador 6.1.1, restando dúvidas sobre sua contribuição para orientar políticas tendo em vista a universalização dos serviços. Sobre outros indicadores, como os de governança participativa e gestão integrada, são baseados fortemente em processos e não em resultados práticos, sendo insuficientes no caso de países em desenvolvimento como o Brasil. São sugeridos novos indicadores para o ODS 6, além dos 11 atualmente medidos, de modo a cobrir todas as diretivas presentes nas suas oito metas.
CONSTRUCTAL DESIGN APPLIED TO INVESTIGATE THE INFLUENCE OF GEOMETRY ON THE MASS FLOW RATE OF AN INCLINED PASSIVE WALL SOLAR CHIMNEY ATTACHED TO A ROOM

Published: November 2023

The present work aims to analyze the turbulent flow in an inclined passive wall solar chimney attached to a room, evaluating the influence of its geometry on the thermal performance of the building (measured by the mass flow rate in the chimney exit) by means of Constructal Design. The flow is considered turbulent, incompressible, under natural convection heat transfer, transient and in a two-dimensional domain that simulates a solar chimney attached to a room. Time-averaged conservation equations of mass, momentum, and energy are numerically solved with the finite volume method using the commercial package FLUENT. For closure modeling of turbulence, it is employed the standard k – ε model. Chimney and room areas are the problem constraints. Moreover, the problem is subjected to three degrees of freedom: the ratio between the inlet opening size and chimney height (Hi/Ha) (which is maintained constant in the present investigations, Hi/Ha = 0.05); ratio between the width of inferior base of the chimney and its height (Wg/Ha); and the ratio between the exit air gap and the inferior base widths of the chimney (We/Wg). The latter two degrees of freedom are varied. Results showed that the degrees of freedom analyzed have a strong influence on the mass flow rate of the air in the building, confirming that the geometrical configuration of solar chimney can be important for the improvement of thermal conditions on the attached building.
COMPARISON BETWEEN TWO WAYS OF MODELING THE FLOW RESISTANCE IN A POROUS MEDIUM
Authors: Pereira G. S. , Oliveira C. P. , Souza J. A.
Published: November 2023

Pieces manufactured from polymeric composites are known for their good mechanical properties and low specific weight. However, controlling their fabrication process requires precise knowledge of the reinforcement and resin physical properties. This is needed to ensure that defective composites are not manufactured. Investigations into these materials physical properties are generally carried out experimentally, which makes it difficult to observe what happens on microscale level. Present work aims to analyze, and compare, flow behavior in a porous medium using two approaches: a) flow resistance is modeled with Darcy's Law, and b) fluid flow is solved through the reinforcement fibers in a micro-sample level. Medium permeability determination was used in results comparison. A good quantitative agreement in predictions obtained with both methods was observed.

Published: November 2023

Duplex stainless steels are widely used in the chemical, nuclear and oil and gas industries. They have an austenitic-ferritic microstructure, in equal parts. In this work, the impacts on the mechanical properties, on the metallographic behavior and the analysis of the residual stresses caused after the welding process by coated electrode were analyzed. In these analyses, a specimen produced from a 10 mm thick duplex sheet was welded, and tensile tests, micrography and residual stress analysis by x-ray diffraction were carried out. The tensile test results showed values higher than those required by the material's manufacturing standard. The specimens broke in the base metal during the tests, indicating that the welding parameters were properly specified and applied to the specimen. The metallographic analysis showed an increase in the ferritic phase in the weld region, which makes this region susceptible to pitting corrosion in environments containing chlorides. Residual stress analysis showed tensile stresses in the weld bead, in the longitudinal and transverse directions, and in the HAZ and in the root compressive stresses in the transverse direction and tensile stresses in the longitudinal direction. These stresses must be considered in the design of equipment and structures manufactured from this steel and when using coated electrode welding, to avoid premature failure, especially fatigue failure.

Published: November 2023

Alternative treatments to urban solid waste (USW) landfill and its integration with biomass can generate social, economic, and environmental benefits beyond contributing to the just energy transition in the Carboniferous Region of Santa Catarina State (Brazil). In this paper, were collected and analyzed data on generation, quantity processed, and current USW treatment practices, as well as rice and forest biomass, aiming to identify the potential for application in the development of USW-derived fuel and biomass that can be used in the energy and industrial markets. In 2020, 236,272.2 t of USW were produced by the forty municipalities considered, with 50% concentrated in just five of these. With only three landfill sites in this region, many municipalities dispose of their USW at a distant location, which increases the overall cost of waste management for the municipalities. The total forest biomass handled in 2019 was 2,135,704.31 tons, and rice husk and straw (2020/2021 harvest) were 999,750.00 tons. Based on this amount and the analysis of the points of concentration of these materials, alternative treatments are being studied with a focus on adding value to the waste chain and advances in the development of the waste management sector in Santa Catarina and in Brazil.

The editorial of Thermal Engineering of this issue continues the discussion on scientific research needs in vital areas in which thermal engineering has important participation. The main goal is to motivate the readers, within their specialties, to identify possible subjects for their future research. The naval sector dominates global commerce totalizing more than 80% of volumes transported]. Heavy fuel oil and marine gas oil are the most utilized fuels and make up 2 to 3% of the human produced CO2 dumped in the atmosphere. Until the year 2050, the International Maritime Organization (IMO) is committed to a 50% reduction of ship greenhouse gases (GHG) emissions with predicted full elimination by 2100. However, military ships are expected to require ten times more electric power than current navy vessels. As a result, the all-electric military ship initiative depends heavily on scientific research and development of environmentally benign high density power generation systems. In that scenario, fuel cells bring a possible path to problem solution. The low-temperature Polymer Electrolyte Membrane Fuel Cell (PEMFC) is recognized to be the most popular FC. Although PEMFC has been used in transportation (e.g., vehicular, ships), PEMFC general use still brings several concerns, due to some shortcomings (e.g., water management, platinum content, Nafion membrane high cost, free energy demanding H2 availability). In parallel, there has been a demand to develop innovative and environmentally correct technologies for alternative energy sources to replace traditional fossil and nuclear sources, including the naval sector, for quite a while, and this need is current, and the main hurdles to overcome are the generation and storage of renewable energy in a technically and economically viable way.  The mission of Thermal Engineering is to document the scientific progress in areas related to thermal engineering (e.g., energy, oil and renewable fuels). We are confident that we will continue to receive articles’ submissions that contribute to the progress of science.

Published: November 2023

The study aimed to determine the relationship between community engagement and project performance in the Child Centered Development Project in Rwamagana District, Rwanda (CCDP). The objectives were to assess the influences of community participation on project performance, determine the influence of community knowledge and skills on project performance, and assess the influence of community accountability on project performance. The study used both descriptive and analytical research designs, with a sample size of 2056 beneficiaries. Data collection was conducted through questionnaires and interviews for primary data, and documentary review for secondary data. The findings showed minimal participation from respondents in the initial stages of the project, with 47.7% stating their participation was nil and 42.9% small. However, 82% of respondents considered their leadership roles excellent or good. Most respondents believed that community level of understanding was the main factor influencing participation, with 89.1% indicating their knowledge and skills significantly influenced project performance. Additionally, 73.3% reported increased community accountability through participation in project monitoring and evaluation. The Pearson correlation between community participation, knowledge and skills, and project performance was positive and statistically significant, with varying degrees of significance. Multiple regression analysis also showed positive and significant regression coefficients, with a reported R2=0.875 indicating that community engagement significantly contributed to project performance at 87.5%. The researcher recommends that project managers conduct feasibility studies to identify key stakeholders and actively engage them in the project.

Scott Joplin in the Overworld: Super Mario's Rag-Inflected Score
Authors: Heazlewood-Dale James C.
Published: November 2023

A rolling banjo, walking bass, steel drum, and syncopated piano. What strange music to accompany your trials and tribulations throughout the Mushroom Kingdom. Eclecticism pervades the Mario franchise and manifests in its digital places, the ways players interact within them, and, indeed, the sounds emanating from them. Mario and his jumping adventures have long been in the hearts of players, the minds of scholars, and the ears of ludomusicologists. By engaging with Koji Kondo's scores for early Mario games, this article highlights an overlooked component in the iconic scores of early Super Mario games: ragtime music. Furthermore, this research contributes examples of African American and Latino musical creation and innovation to ludomusicological discourse. I argue that, as a means to connect, contextualize, and enhance Mario's movement with music, composer Koji Kondo draws from ragtime and early jazz styles because of their distinctive rhythmic qualities. His rag-inflected score establishes ragtime as fundamental to early Super Mario soundscapes. While a substantial ludomusicological body of literature focuses on the Western classical tradition in games, jazz-centered research is scarce. This cross-disciplinary research draws on a wide range of scholarly perspectives from jazz studies and ludomusicology, including work by Andrew Schartmann, Edward Berlin, Ingrid Monson, Neil Lerner, David Butler, and Charles Hiroshi Garrett. As game audio is indispensable in facilitating a player's sense of verisimilitude of Mario's imaginative and, at times, nonsensical worlds, an inquiry into how jazz participates in this unique audiovisual relationship is long overdue.
Query Recommendation System in Social Networks

Published: November 2023

Recommender Systems are software which provides suggestions to the user according to his or her interest. These suggestions are related to supporting users in making their decisions, for example, what to search, what to buy, what to listen, etc. Recommender systems are very important in online stores where there are a lot of items to buy. These recommender systems help user to find things according to their interest and buy them. There are a lot of techniques proposed for recommendation and used in commercial environments. People are thought to trust suggestions from friends more than those from websites that are similar to them [2]. As a result, it is helpful to feed a recommender system with the friends' ratings. However, social media sharing websites' recommender systems have several difficulties, such as ranking the information from the user's friends as well, finding information from other sources in comparison to the user's immediate friends, and using metadata and context links for suggestion. In this research, an architecture based on profile-based crawling of social media sharing websites is proposed for query recommendation.

Neutrosophic Multi-Criteria Decision-Making Methodology to Identify Key Barriers in Education
Authors:   College of Technological Innovation, Zayed University, Dubai, UAE, Taher Fatma
Published: November 2023

Various educational barriers have negative impacts on teachers, organizations, and students. Identify these barriers and introduce some strategies that give benefits to organizations. There are different conflicting barriers, so the concept of multi-criteria decision-making (MCDM) is used to deal with these barriers. We proposed an MCDM Framework to evaluate the education barriers and rank strategies to select the best one. We suggest a TOPSIS method to rank the alternatives. The TOPSIS method is integrated with the neutrosophic set to deal with uncertain information. The weights of the criteria are computed with the mean method. We collected ten barriers and nine strategies in this study. The results show that Promoting teacher motivation is the best of the nine strategies. We created a sensitivity analysis to show the model's effectiveness and the results' stability. The sensitivity analysis is made by changing the criteria weights and ranking the strategies. The results show that promoting teacher motivation is the best in all cases in sensitivity analysis.
Influence of setting time and compressive strength for coal bottom ash as partial cement replacement in mortar
Authors: Al Biajawi Mohammad I. , Embong Rahimah
Published: November 2023

Environmental degradation from forestry practices to extract limestone from mountains, as well as subsequent calcination in cement factories and dumping of coal bottom ash (CBA) waste from thermal power plants, are among the wastes from industry. However, it is essential for the construction industry to look for sustainable solutions to mitigate the negative impact on the environment. In order to promote an environmentally friendly and sustainable ecosystem, the use of recycled CBA waste as a partial substitute for cement in the manufacturing process has significant potential to mitigate the environmental damage caused by the two distinct sectors of cement and waste management. A series of six mortar preparations were prepared, each containing varying percentages of CBA as a partial substitute for cement. The percentages used ranged from 0% to 50% by weight of cement. The time tests were performed on freshly prepared pastes. All samples were cured with water until the respective test time was reached. The experiment included the evaluation of the compressive strength of hardened mortar cubes at three different time intervals: 7, 14 and 28 days. The findings of the study demonstrate that the incorporation of CBA as a partial substitute for cement affects both the setting time and the compressive strength of the mortar. It has been shown that the use of up to 20% CBA as a cement replacement effectively increases the compressive strength of the mortar. Conclusively, the successful use of CBA as a partial substitute for cement in the manufacture of mortar has the potential to reduce the amount of cement consumed, eliminate the need for landfill space for waste disposal, and contribute to the production of a more sustainable environment, thereby promoting a better lifestyle for the surrounding population.

Introduction: Combined skin diseases represent the fourth leading cause of non-fatal disability worldwide. In 2013, it was estimated that skin diseases represented almost 2.0% of the total global burden of disease. Different fasting models have been studied in an attempt to understand the effect of fasting on skin structure and function. Objective: It was to present the main scientific evidence of the effects of calorie restrictions and intermittent fasting on skin health. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from July to September 2023 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 119 articles were found, and 26 articles were evaluated in full, and 23 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 22 studies with a high risk of bias and 26 studies that did not meet GRADE and AMSTAR-2. Most studies showed homogeneity in their results, with X2=64.7%>50%. It was concluded that although calorie restriction is the most effective intervention to prolong the life of organisms and prevent age-related diseases, its effects on aging and skin diseases can be significant. Dietary lifestyles can affect epithelial lineages such as the skin and intestine. The impact of Ramadan fasting on skin health can be compared with the effect of other types of fasting, including periodic dieting, calorie restriction, dietary restriction, dietary manipulation, and intermittent, short-term, and prolonged fasting. However, despite the scarcity of studies on the topic, no serious health risks have been reported and, therefore, patients who wish to fast should be warned about the importance of continuing their treatment and the administration of transdermal/topical medications.

Objective To investigate the incidence, trends, and survival rates of all gynecologic cancers using the Korea Central Cancer Registry (KCCR) database from 1999-2019.Methods Gynecologic cancer data were obtained from the KCCR database between 1999 and 2019. Age-standardized incidence rates (ASRs), annual percentage changes, and average annual percentage changes (AAPCs) were calculated. The relative survival rate (RSR) was reported by age group, stage, and 6-year period (I: 1999-2005, II: 2006-2012, III: 2013- 2019).Results The gynecologic cancer ASRs were 26.2 and 24.9 per 100,000 individuals in 1999 and 2019, respectively. Trends of incidence in gynecologic cancer revealed a decrease in cervical cancer and gestational trophoblastic neoplasia (GTN) with AAPCs of -3.4 and -4.3, respectively. Conversely, the incidence of uterine, ovarian, and vulvar cancers increased with AAPCs of 4.7, 2.3, and 2.1, respectively. AAPC for vaginal cancer showed no change. The 5-year survival rate was highest for GTN (90.5%) and lowest for vaginal cancer (56.6%). An increase in age was correlated with poorer survival rates across all gynecologic cancers, excluding vaginal cancer. For all gynecologic cancer types, the prognosis deteriorates with advancing cancer stages. The RSR of uterine cancer improved consistently across all periods. The ovarian cancer RSR improved more in period III than in periods I or II. Additionally, the vulvar cancer RSR improved more in periods II and III than in period I.Conclusion In Korea, the incidence of cervical cancer and GTN decreased, whereas the incidence of uterine, ovarian, and vulvar cancer increased from 1999 to 2019. The RSR for uterine, ovarian, and vulvar cancers showed consistent improvements over different periods. Effective screening programs and the adoption of advanced treatments may be necessary to further reduce the burden of gynecologic cancer.

Published: November 2023

The segmentation of MR brain images using this method is based on K-means clustering, feature extraction using a discrete wavelet transform (DWT), and feature selection using a grey level co-occurrence matrix (GLCM). For this procedure, we have used a Perfect Radial Basis Function (RBF) - Support Vector Machine (SVM) Classifier. Based on fractions of selectivity and sensitivity, the classifier's performance was measured in terms of accuracy. The proposed classifier was found to be 93% accurate. Additionally, the Histogram methodology was applied in this proposed method in place of randomly choosing the cluster centres. Keywords: K-means clustering, Histon creation, Discrete Wavelet Transform (DWT), GLCM feature selection, and RBF- SVM Classifier.

Authors: Journal IJSREM
Published: November 2023

As artificial intelligence technology has advanced, it has become commonplace to employ hand gesture detection to control virtual objects. The suggested system in this research is a hand gesture-controlled virtual mouse that uses AI algorithms to recognize hand gestures and transform them into mouse movements. People who have trouble using a conventional mouse or keyboard can use the system to provide an alternate interface. The suggested method takes pictures of the user's hand with a camera, which an AI program then utilizes to identify the motions the user is making. Since the development of computer technology, the method for constructing a process of human- computer interaction is advancing. The mouse is one of the best pieces of HCI (Human-Computer Interaction) technology ever created. This article suggests an HCI-based virtual mouse system that makes use of hand movements and computer vision. webcam or built-in camera recordings of gestures that have been subjected to a color segmentation and detection procedure. This system uses a webcam or an integrated camera to capture frames. It then processes the frames to make them trackable, identifies various user motions, and executes mouse functions. In order to make the interaction more effective and dependable, this study suggests a vision-based system to control various mouse behaviors, such as left and right clicking, using hand gestures. This system uses a webcam or an integrated camera to capture frames. It then processes the frames to make them trackable, identifies various user motions, and executes mouse functions. Therefore, the suggested mouse solution removes the need for a device to use a mouse. Therefore, it can be seen that the development of HCI technology is advantageous.

Published: November 2023

Fruits and vegetables are essential for human life. Maintaining the quality and safety of fruits and vegetables are critical challenges for the food packaging industry in this decade. Chitosan and starch are most widely used for food packaging as they bring unique properties for packaging applications. Chitosan has good antimicrobial properties but weak water vapor permeability. Meanwhile, starch has a better water vapor barrier but has poor mechanical properties. This paper discusses the application of chitosan and starch blends in the field of films and coatings. Several characteristics, such as mechanical, thermal, antimicrobial properties, solubility, and water vapor permeability, are also discussed. This review also discussed several applications of chitosan-starch-based films and coatings for the preservation of fruits and vegetables.
