Charcoal fines are co-products of the wood carbonization process, unwanted because they reduce the gravimetric yield of the main product, charcoal. It can be produced due to the carbonization process, during the storage and transport of charcoal. Pelletizing charcoal fines increases the energy density of this material, producing a homogeneous fuel with lower moisture content, enabling burning in equipment with high energy efficiency, in addition to desirable properties in energy products such as high fixed carbon content and low moisture content. This study evaluated the effect of moisture content and drying time on the production of black pellets from charcoal fines bound with rice starch (Oryza sativa) on the physicochemical and mechanical characteristics. Black pellets were produced using two proportions of water (10 or 20%) and a drying time of 4 or 6 hours. Black pellets were evaluated for their proximate analysis, elemental composition, moisture content, size, apparent density, calorific value and energy density. The addition of water did not affect the content of volatile matter, ash, and fixed carbon, while the treatment with addition of 20% water and four hours of drying showed a higher moisture content (3.34%). The addition of water allowed for better heat conduction and particle arrangement, producing pellets with a durability greater than 98%. The better arrangement promoted by the addition of 20% water also increased the density of the pellets, resulting in greater energy density. Black pellets can be considered an alternative for residential heating, with T3 treatment (20% - 4h) with a high energy density and better performance in terms of desirable properties for use and commercialization according to the standard EN 14961-6.

Authors: García Maria , Ramírez Benito , Cesín Alfredo , Juárez José
Published: May 2024

La vivienda indígena está marcada por el arraigo cultural de sus habitantes, producto de un conjunto de valores, elementos y modos de concebir la vida y el espacio que le otorgan identidad. Esta investigación se realizó en Lipuntahuaca, comunidad Totonaca enclavada en la Sierra Norte del estado de Puebla, México. La información se obtuvo mediante un muestreo estadístico a 77 viviendas donde, a partir de un análisis arquitectónico, se determinó su composición espacial, sus cambios y el reflejo de la identidad cultural en la vivienda indígena. Los resultados muestran que, pese al paso del tiempo, su configuración espacial permanece sin cambios significativos, y presenta una clara continuidad en su composición material y simbólica, con rasgos ancestrales que persisten a través del tiempo. Esta es producto de las arraigadas celebraciones tradicionales que acompañan a la vida ceremonial totonaca de manera cíclica, y del gran tamaño de las familias.

Ivan Illich perspective of deschooling society and the right of education
Authors: Peixer Janaína Freiberger Benkendorf
Published: May 2024

For over a century, schools have been able to institutionalize the value behind learning and “earning” an education.  Ivan Illich argues that most learning was not the result of instruction, but of active engagement in a meaningful setting. He questions the system that encourages everyone to access an education that is guided by socio-economic relations, as pre-formatted product. This study aims to investigate if the theory of education proposed by Ivan Illich in Deschooling Society is feasible, legal, and how can it influence the creation of better models of education. The paper addresses the right to education according to the Universal Declaration of Human Rights and to what extent a parent has the ultimate authority to direct a child’s education. Using the review literature methodology, it investigates what is the role of school and what is the proposition of Ivan Illich for an alternative system of education. By reflecting on problems and contradictions of the tradition school system the paper discusses if schools contribute to a more democratic and egalitarian society, or if they reinforce inequalities. As a conclusion, Ivan Illich believes that the biggest obstacle to achieving a society that really educates is the existing imaginary that is conditioned to schooled thinking. Illich advocated for the decentralization of education and the empowerment of individuals to take control of their own learning processes. He promoted informal learning through community-based initiatives, apprenticeships, and self-directed study. This perspective has influenced alternative education movements and contributed to the development of concepts like homeschooling, unschooling, and self-directed learning. Alternative models of education can bring creativity and innovation to the learning process and should be encouraged and celebrated, especially if guided by an emancipatory approach and not by a neoliberal market logic that reinforces inequalities.

Authors: Bezaou Ferdous , Izemmouren Ouarda , Guettala Salim
Published: May 2024

The primary motivators behind the renewed focus on employing locally available materials, recycling industrial waste, and utilizing their characteristics for adobe bricks are cost-effective building materials, thermally efficient, consuming less energy and reducing environmental emissions. In light of this, this study examines how the physical characteristics and mechanical behavior of quicklime-stabilized adobe bricks' are affected when dune sand (DS) and crushed fired brick waste (CB) are combined. The thermal conductivity of adobe bricks was also studied. According to the data, the compressive and flexural strengths significantly improved with the addition of 40% CB. A slight strength increase was observed with the incorporation of 20% DS, which is not the case for the other types of sand. Addition of 20% DS to the mixtures resulted in a decrease in the TA and Cb. SEM technique confirmed that the use of CB and DS in the adobe bricks preparation procedure resulted in a reduction of voids in the matrix, thereby improving the characteristics, especially their physical characteristics. Additionally, there was an improvement in the apparent density when the M1 combination was included. This resulted in an increase in the speed at which ultrasonic waves propagated. Similarly, M3 combination helped to reduce the TA and Cb. With regard to M1 combination, it increased the compressive and flexural strength of adobe bricks by 71.75% and 52.23%, respectively, as compared to the RB. Significant increases in elasticity modulus were observed in compression and flexion. The combination of CB and DS slightly increased the thermal conductivity.
Active and passive soil wedges influence on the natural frequency of retaining structures
Authors: Lyazid Guechi , Abdelhak Bordjiba
Published: May 2024

Studying the behavior of retaining structures has been very important issue due to their large application in civil engineering. An accurate determination of the earth pressure and the natural frequency is elemental for studying the dynamic behavior of these structures. In the most previous investigations, the soil backfill was considered sufficient width as rectangular mass whereas in the real. the backfill behind retaining structures repartitioned as triangular active and passive soil wedges. Rectifying this weakness, this study proposed an analytical model for calculating the natural frequency of retaining structures by considering the triangular active and passive soil failure wedges, which take into account the variation of earth pressure behind retaining structures. The soil wedge causes an increase in the value of natural frequency. It is clarified that the soil wedge has a large influence on the natural frequency of retaining structures. In this regard, the consideration of active and passive soil wedges behind retaining structures plays an important influence in determining of the natural frequency.

Published: May 2024

Gas turbines are a well-known rotating machines used in a variety of industrial sectors.  However, the aforementioned turbines are highly sensitive to climatic changes such as variations in temperature and humidity, which can significantly affect their performance. Focusing on the being cited limitations, and aiming at the improvement of the system performances, it is important to control the ambient air temperature. In this context, the current study analyzes the design of an enhanced air-cooling system by putting forth a novel and practical method for raising output while lowering investment costs and ensuring steady and dependable operation. Firstly, the thermodynamic analysis of the realistic MS-7001 is carried out. Then, the feasibility of an air-cooling system for the MS-7001 turbine used at the Natural Gas Liquefaction complex – Skikda is conducted before starting the prototyping process. The proposed system uses a water evaporative cooler as a pre-cooler to reduce the temperature by around 12°C, while, increasing the relative humidity to around 90%, In order to ensure the thermal effectiveness of the system, a compressed air injection station is used for the production of a cold air at high pressure. CFD analysis results and conducted experiments on the proposed prototype have confirmed that it is effective and can be adapted to both wet and dry climates, even under hard variations. The adopted technique enhances the system efficiency and makes it possible to maintain the nominal operating point of gas turbines independently of external variations of atmospheric condition, without modifying their composition, which minimizes investment, development and maintenance costs.

Published: May 2024

Although the great advance in term of AC machine construction, control strategies are also necessary to be developed and improved continuously satisfying output torque/power. Hence the Doubly fed induction motor (DFIM)is widely used in industry, since it can operates in wide range of speed variation around the synchronous speed and the control of ﬂux and torque is independent. In this paper, control of doubly fed induction motor (DFIM) has been investigated, which two control strategies have been studied and compared: the first strategy uses a sliding mode control (SMC); the second employs Direct Torque Control (DTC). Modeling of DFIM and details of both control strategies have been presented. the mathematical description of different basic dynamic models of the DFIM have been carried out The performances in terms of torque tracking, accuracy and robustness of both control techniques under normal and various speed and load conditions have been demonstrated and compared.

Published: May 2024

Understanding the delicate interplay between geometric design principles and dynamic responses is vital for numerous engineering applications because it allows optimization of structural integrity and performance for manufacturing and special use of this structures. In this study, a complete numerical analysis is undertaken to investigate how differences in geometric parameters impact the structural behaviour of a cantilever smart trapezoidal beam, giving useful insights for engineering applications. The beam consists of a host structure made of aluminum couple with two piezoelectric layers on its top and bottom surface. For such purpose, the study a 3D finite element model has been implemented in ANSY APDL and applied by Matlab we used the interfaces between the two software, considering that the beam changes its form in the axial direction following polynomial based function. The function takes two geometric parameters as an input which are the tapering ratios and the degree of non-uniformity. The beam is then subjected to a harmonic based excitation and the effect of changing tapering ratios and the degree of non-uniformity is analyzed., allowing analysis of the effects of altering tapering ratios and the degree of non-uniformity The results led to a conclusion that just by manipulating the mentioned parameters a considerable changing in the fundamental frequency and the amplitude has been noticed. Addition our numerical analysis shows that small changes to the tapering ratios and degree of non-uniformity have a considerable influence on the behavior of cantilever smart trapezoidal beams. These discoveries add to continuing research in smart materials, paving the road for creative engineering solutions.

Authors: Fourar Yasmine , Melkemi Khaled , Brahimi Mahmoud , Boussaad Abdelmalik
Published: May 2024

In this paper, we propose a novel method for designing non-stationary biorthogonal wavelets that leverages Bezout equations to compute wavelet filter coefficients. Our approach integrates cardinal Chebyshev B-splines of varying degrees (second, third, and fourth) as bases for constructing these wavelets, providing explicit formulations for both low-pass and high-pass filters at all levels. By employing this method, we streamline the design process, making it more efficient and accessible while accommodating diverse processing requirements. The utilization of Bezout equations offers a systematic framework for deriving wavelet filter coefficients, enhancing the reproducibility and reliability of the design process.  This systematic approach ensures that the resulting wavelets possess desired properties such as vanishing moments, smoothness, and optimal localization. Moreover, by incorporating cardinal Chebyshev B-splines, we can effectively capture intricate signal and image features, addressing challenges encountered in traditional wavelet design methods. Our method not only simplifies the design process but also provides a comprehensive solution by explicitly formulating filters and dual filters across all levels. This comprehensive approach ensures that the resulting wavelets meet the specific demands of applications in signal and image processing, including compression, denoising, and pattern recognition. These advancements hold significant implications for various domains, including information technology, healthcare, and engineering, where efficient and reliable processing techniques are crucial. Moving forward, it is imperative to refine algorithms, assess parameter robustness, and conduct thorough empirical validations across diverse datasets and application scenarios. This will ensure the efficacy and scalability of our proposed method and pave the way for further advancements in non-stationary wavelet design and its applications. By continuously improving and validating our approach, we can foster innovation and enhance practical outcomes in a wide range of fields.

O Acidente Vascular Encefálico (AVC) é globalmente a segunda principal causa de morte e a terceira principal causa de perda de anos de vida ajustados por incapacidade. As terapias de recanalização para AVC isquêmico (AVCi) agudo incluem a administração intravenosa de medicamentos trombolíticos e terapias intra-arteriais, como a trombectomia endovascular. Alcançar a reperfusão completa é o preditor modificável mais importante para maximizar o efeito do tratamento da trombectomia mecânica (TM). Dessa forma, com o crescente corpo de literatura sobre os avanços da trombectomia no acidente vascular encefálico isquêmico, foi possível a realização de uma revisão integrativa de literatura por meio da plataforma PubMed, com seleção e análise criteriosa dos artigos, a fim de revisar e analisar as evidências atuais sobre os aspectos da trombectomia mecânica no AVCi. Nesta revisão foi identificado que a trombectomia endovascular e as técnicas intra‐arteriais são terapias de recanalização em que o coágulo sanguíneo é removido utilizando um dispositivo mecânico, ou medicação trombolítica injetada por via intra-arterial diretamente no coágulo sanguíneo. Assim, nota-se maiores chances de bom resultado funcional em pacientes no grupo de trombectomia em comparação com o grupo sem trombectomia. Além disso, os fibrinolíticos IA podem melhorar a reperfusão após TM falhada ou incompleta. Por fim, a terapia endovascular encurta o tempo de internação hospitalar, aumenta o tempo de permanência em casa e resulta em situações de vida mais desejáveis ​​nos 90 dias pós-AVC. Portanto, conclui-se que, o tratamento com trombectomia foi associado à melhor resultado funcional e menor risco de mortalidade em pacientes com AVCi, entretanto, há como limitação, o pequeno número de artigos disponíveis sobre a relação clara entre a realização de trombectomia mecânica no tratamento do AVCi agudo e o prognóstico do paciente.

Introdução: A Hipertensão Arterial Pulmonar (HAP) tem uma ampla lista de etiologias, dentre elas podemos destacar as cardiopatias congênitas (CC), que podem resultar na comunicação das circulações sistêmica e pulmonar no coração, resultando no aumento do fluxo pulmonar, com aumento da pressão e resistência vascular nesse órgão. A Síndrome de Eisenmenger (SE) representa um quadro irreversível, indicando o quadro severo e final da HAP, com shunt reverso ou bidirecional, resultantes de defeitos não reparados, levando a sintomas clínicos de baixa saturação de oxigênio, cianose e distúrbios sistêmicos. Objetivos: Descrever a associação entre hipertensão pulmonar e cardiopatia na síndrome de Eisenmenger. Métodos: Trata-se de uma revisão sistemática da literatura, na qual os artigos foram selecionados nas bases de dados Sciencedirect, PubMed, MedLine e Lilacs. Os descritores utilizados foram “pulmonary hypertension AND Eisenmenger AND heart”. Os filtros aplicados foram: 10 years, humans. A partir de 209 artigos disponíveis, foram selecionados 25 após a leitura inicial dos títulos, resumos e excluídos os repetidos e que não se enquadraram ao tema, restando 23 artigos para compor a revisão. Resultados: A SE é o fenótipo mais grave e extremo da hipertensão arterial pulmonar associada a CC, envolvendo-se grande número de shunts não restritivos sistêmicos da esquerda para a direita, o que desencadeia desenvolvimento de vasos vasculares pulmonares, hipertensão arterial pulmonar progressiva, aumento da resistência da vascularização pulmonar por transmissão da pressão sistêmica para a artéria pulmonar e, consequentemente, sobrecarga do ventrículo direito. Assim, pacientes com SE associada a hipertensão arterial pulmonar (SE-HAP) apresentam risco aumentado de trombose da artéria pulmonar, com aumento simultâneo do risco de hemoptise e hemorragia pulmonar. Os estudos evidenciaram que pacientes com SE diagnosticado têm maior sobrevida do que pacientes com outras causas de HAP. Porém, a expectativa de vida global é semelhante em pacientes com SE-HAP ou com HAP idiopática ou secundária. Nota-se também como manejo não operatório é cada vez mais importante no tratamento de casos complexos. Conclusão: Foi evidenciado que a SE apresenta-se como uma forma grave de HAP associada à CC, acarretando em uma menor sobrevida em relação a pacientes de HAP sem a síndrome.

O presente artigo é um recorte da dissertação de Mestrado vinculada à linha de pesquisa Formação de Professores, Currículos e Práticas Inovadoras do Programa de Pós-Graduação em Educação do Centro Universitário Adventista de São Paulo (UNASP). Aborda a formação do professor de espanhol e reflexões sobre políticas educacionais e ensino de línguas, com foco na inclusão de estudantes surdos e constatou que, apesar dos avanços no que se refere à educação inclusiva, desafios persistem no contexto escolar. A pesquisa qualitativa, de natureza exploratória objetivou investigar a formação e a prática docente de língua espanhola, para nos informar da oferta de cursos de formação continuada no estado do Espírito Santo, os quais visem à capacitação de professores de língua espanhola para atuar no âmbito da educação inclusiva, especificamente com estudiantes surdos. Utilizamos como metodologia a observação de sala de aula e a entrevista semiestruturada. Participaram da entrevista três professoras de espanhol do ensino médio de três escolas da rede estadual do Espírito Santo. Para desenvolver o estudo, apoiamo-nos em outras pesquisas relacionadas ao tema, destacando os estudos de Teixeira (2016) e Sousa e Silveira (2016). Os resultados indicam que os professores não estão preparados para ensinar educandos surdos, devido à falta de formação inclusiva em sua formação inicial e continuada, o que os leva a práticas pedagógicas ineficazes. Espera-se, com este estudo, inspirar educadores e legisladores para uma reflexão sobre práticas inclusivas, promovendo uma educação fundamentada no respeito, equidade e qualidade, visando ao desenvolvimento pleno de todos os estudantes, tanto surdos quanto ouvintes.

Natural resources, such as soil and water, play a crucial role in sustaining life on Earth. When used appropriately, these resources can mitigate environmental impacts. However, inadequate soil management practices can result in negative effects, such as the intensification of erosion processes and significant losses of soil, water and nutrients essential for plant growth. Thus, considering that the Farinha River basin - MA is located in the Cerrado biome and has a large part of its area occupied by highly erodible soils, the aim was to quantify water, soil and nutrient losses using a rainfall simulator. The experimental design adopted was entirely randomised (DIC), in a bifactorial scheme with 5 replications. Factor 1 considered two types of soil management systems (Anthropised Area and Non-Anthropised Area), while factor 2 involved three simulated rainfall intensities (80mm.h-¹, 110mm.h-¹ and 130mm.h-¹). The response variables assessed were losses of water, soil and nutrients and organic matter.The averages were subjected to analysis of variance and, if significant, the Tukey test was applied at 5% probability using Past 4.03 software. The results indicated significant losses of soil, water and nutrients associated with both the soil management system and the rainfall intensities, as well as making it possible to quantify the nutrients lost in runoff water on site. The conclusion is that the combination of inadequate soil management practices and intense rainfall can exacerbate erosion processes and the leaching of macro and micronutrients, resulting in an increasing need to incorporate fertilisers and correctives into agroforestry activities. Furthermore, it is important to emphasise that water erosion also contributes to an increase in soil and nutrient loss, which can lead to adverse environmental impacts, such as contamination of water resources and degradation of soil quality.

Chronic total occlusion (CTO) sores in coronary arteries present a challenge in percutaneous coronary intervention (PCI) because of their complex anatomy and high rates of procedural failure. Objectives: In this comparative study, we aim to investigate the safety and feasibility of rotational atherectomy (RA) versus conventional stenting in patients with chronic total occlusion (CTO) lesions. Methods: This comparative study was conducted at Ayub teaching hospital from September 2023 to December 2023. Data was collected from 110 patients from both genders. Patients aged > 18 years and diagnosed with chronic total occlusion (CTO) lesions in coronary arteries confirmed by coronary angiography were included in the study. Baseline demographic and clinical data, including age, gender, comorbidities, and angiographic characteristics, were collected for each participant. Additionally, procedural details such as the type of intervention, rotational atherectomy, conventional stenting, procedural time, fluoroscopy time, contrast volume, and any adverse events encountered during the procedure were recorded. Results: Data were collected from 110 patients from both genders. The mean age of participants in the Rotational Atherectomy (RA) group was 62.4 ± 7.3 years, while in the Conventional Stenting group, it was 61.8 ± 6.9 years. There were 40 males and 15 females in the RA group, compared to 38 males and 17 females in the Conventional Stenting group. The prevalence of diabetes mellitus was 42.0% in the RA group and 45.5% in the Conventional Stenting group. Left ventricular ejection fraction (LVEF) was 53.7 ± 4.2% in the RA group and 54.1 ± 4.5% in the Conventional Stenting group. The RA group showed a success rate of 81.8%, and the conventional stenting group achieved a success rate of 90.9%. However, the RA group experienced slightly higher rates of major procedural complications (9.1% vs. 5.5%) and minor procedural complications (12.7% vs. 10.9%) than the conventional stenting group. Conventional stenting group, the mean change was -1.2 ± 0.7. Additionally, the incidence of target lesion revascularisation (TLR) was observed in 8 patients (14.5%) in the RA group and 12 patients (21.8%) in the conventional stenting group. Furthermore, major adverse cardiovascular events (MACE) occurred in 9 patients (16.4%) in the RA group and 11 patients (20.0%) in the conventional stenting group. Conclusion: It is concluded that both rotational atherectomy (RA) and conventional stenting are effective and safe treatment options for patients with chronic total occlusion (CTO) lesions. Our findings suggest that both strategies yield comparable procedural success rates, complication rates, and efficacy outcomes, including myocardial infarction frequency, troponin levels, and left ventricular ejection fraction changes.

The rate of rape and other sexually induced crimes is rapidly on the increase worldwide with weak empirical confirmational tools, and expensive financial implications This is further compounded by poor proof of the time of the committal of the crime and its attendant effect on the parameter of interest. This called for a cheap and accurate approach involving the use of biochemical parameters indicative of seminal fluids on fabrics and other ancillary materials found in a crime scene. This study was therefore designed to validate a suitable seminal fluid biochemical approach to detecting seminal stained fabrics and the attendant circadian rhythm effects. Seminal fluid biochemical parameters used for the study include prostate-specific antigen, gamma-glutamyl transferase, acid phosphatase, magnesium, zinc, and inorganic phosphorus. These parameters were analyzed using WHO-approved methods after the extraction phase from dried stained fabrics. Forty (40) participants were recruited for the study divided into two groups; nocturnal and diurnal. The mathematical and empirical analysis data were analyzed using One-way ANOVA (Post Hoc) on an SPSS 25 version platform. The result showed a significant increase (p< 0.05) in seminal PSA, GGT, and ACP in the semen-stained fabrics when compared to distilled water-stained fabrics. In a similar vein, there was a significant increase in seminal ACP and PSA concentrations in the nocturnal group when compared to the diurnal, whereas seminal GGT decreased. In conclusion, this study has shown that semen-stained fabric can be detected for the presence of seminal fluids using seminal PSA, ACP, and GGT. Also, the effect of circadian rhythm should be considered during result interpretation.

The COVID-19 pandemic has become a complicated problem faced by the world. The absence of specific antiviral drugs or vaccines at the beginning of the outbreak made the public health approach the primary strategy for preventing the spread of COVID-19. The lack of transparency at the start of the COVID-19 outbreak also led to public misinformation. WHO called it an infodemic, an excess of information, whether true or not, making it difficult for people to determine valid references. In Indonesia, misinformation on health matters is not a new difficulty and is in the top rank along with socio-political. The government utilizes social media to provide information to the citizens. Social media itself has a vital role in the infodemic as a medium for disseminating information, whether credible or not. The Indonesian FDA plays an essential role in conducting education through social media. This study aims to map the elements forming citizens' engagement in Indonesian FDA social media use, especially in disseminating information about the COVID-19 vaccine. This study uses a regression method with citizens' engagement (calculated from the number of likes and comments) as the dependent variable. Three independent variables form citizen engagement elements: media richness, content production, and content type defined by the government. The sentiment toward government Instagram posts was measured by analyzing citizens' comments using the dataset from InSet Semantic Lexicon. Based on negative binomial regression results, data obtained that the framework developed in this research was statistically significant in observing the phenomenon. Media richness and content production significantly affect citizens' engagement. On the other hand, original and informative content encourages more citizen engagement. Generally, public sentiment on Indonesian FDA Instagram content, both head office and regional offices, tends to be more positive than negative.

Social media is a group of electronic and digital appliances which has its basis on internet and allow sharing, transforming and exchanging ideas, information, educational material and content. In the 21st century, internet usage has been increased significantly. Our life has been entirely changed by the internet and social media. Social media cause different health related issues and academic decline among students. Objective: To observe the relationship between social media use and depression among nursing students. Methods: Cross-sectional analytical study was performed on 120 nursing students. Ethical permission was obtained from Ethical Review Committee, Sohail University, Karachi. Descriptive statistics was performed on demographic variables. Pearson Correlation test was performed to check the relationship between social media use and depression. Results: Beyond 120 participants, males were in majority (57.5%). Mostly (58.3%) participants were in their 1st and 2nd year, 20.8% were married and 69.2% were living with their friends. Largely (77.5%) belong to Generic BSN program and 55.0% partakers were using social media from 0-4 hours per day. Mostly (44.2%) participant have moderate to extreme level of depression. We found positive correlation of social media use with depression.   Conclusions: The findings of this study suggest significant correlation between depression and social media use. Spending more time on using social media can lead to depression. Therefore, policy makers should pay attention in planning to minimize the harmful effects of social media usage among students.
