Authors: Suko Widodo  , Kristama Baswara
Published: August 2024

The goal of this research-based, scientific study is to shed light on how Surabaya's campuses and schools are prepared to handle the demands of modern, convergent digital media and learning methodologies. This study focuses on the in-person teaching and learning process that is scheduled to resume in July 2021 and reshaping society three years after the pandemic. Even while face-to-face instruction will introduce new habits for the new era—the new norm era—schools and campuses must nonetheless adhere to government-established health procedures. The education industry has updated its teaching strategies for this new normal period.  Schools and colleges use information and communication technology-based teaching and learning strategies both online and offline to keep up the teaching and learning process. The issue is that, from facilities to human resources (HR), Indonesian campuses and schools are currently not dispersed equally, especially in major cities like Surabaya. This presents a significant obstacle to Indonesia's educational system. In order to characterize the discourse and social changes that take place during the preparation process of learning techniques employing convergent digital media in the city of Surabaya, this study employs a discourse analysis method with a descriptive qualitative approach. The study's findings and recommendations indicate that, in the new normal period, digital communication media is presently a useful and efficient tool for learning. The new normal era's social shifts in the education sector today base its teaching strategies on the convergence of media and digital technologies.

Authors: K. Abdul Zahra Atheel , A. Wali Wasan
Published: August 2024

This article emphasizes on a strategy to design a Super Twisting Sliding Mode Control (STSMC) method. The proposed controller depends on the device of Field Programmable Gate Array (FPGA) for controlling the trajectory of robot manipulator. The gains of the suggested controller are optimized using Chaotic Particle Swarm Optimization (PSO) in MATLAB toolbox software and Simulink environment. Since the control systems speed has an influence on their stability requirements and performance, (FPGA) device is taken in consideration. The proposed control method based on FPGA is implemented using Xilinx block sets in the Simulink. Integrated Software Environment (ISE 14.7) and System Generator are employed to create the file of Bitstream which can be downloaded in the device of FPGA. The results show that the designed controller based of on the FPGA by using System Generator is completely verified the effectiveness of controlling the path tracking of the manipulator and high speed. Simulation results explain that the percentage improvement in the Means Square Error (MSEs) of using the STSMC based FPGA and tuned via Chaotic PSO when compared with the same proposed controller tuned with classical PSO are 17.32 % and 13.98 % for two different cases of trajectories respectively.
Unravelling the Influence of Advection and Diffusion on the Spatial and Temporal Evolution of Pollutant Concentration
Authors: Mohd Jamil Norazaliza , Khan Ilyas
Published: August 2024

The spatial distribution and temporal evolution of pollutant concentration are complex phenomena. Advection and diffusion are the primary drivers influencing the dynamic of pollutant concentrations. This paper aims to investigate and elucidate the roles of advection and diffusion on pollutant concentration's spatial and temporal evolution in a one-dimensional domain. The finite element method (FEM) is used to solve the governing equation numerically. The underlying concepts of FEM hand-to-hand with MATLAB software were presented. The simulation study revealed that advection and diffusion uniquely impact the system's dynamic. Advection, driven by the bulk movement of water, leads to rapid and long-range transport of pollutants, while diffusion, driven by random molecular motion, causes more gradual dispersion. The interplay between these processes is a critical determinant in understanding the overall behaviour of pollutant concentrations over time and space.
A Geografia do gás na Amazônia brasileira
Authors: Nogueira Ricardo José Batista , Oliveira Neto Thiago
Published: August 2024

O gás natural (GN) e o gás liquefeito de petróleo (GLP) são produtos essenciais na vida moderna e têm ampliada utilidade, que vai além do uso doméstico. A indústria, os serviços e os transportes vêm, gradativamente, promovendo a substituição do óleo combustível, em virtude dos apelos ambientais e por questões econômicas. Isso provocou o surgimento de uma “geopolítica” do gás, associada ao controle das jazidas por empresas e Estados-nacionais, dos percursos dos gasodutos e do seu transporte e distribuição. O objetivo deste artigo é mostrar o circuito espacial da produção desse produto no Brasil, as empresas que controlam o abastecimento desse produto no país e as redes constituídas para assegurar a produção e a distribuição. Foram realizados levantamentos bibliográficos e entrevistas nas distribuidoras de gás encanado e de botijões de GLP na cidade de Manaus. Um destaque é dado para a exploração e distribuição na Amazônia, região que possui uma das maiores jazidas em terra do país. Mostram-se o planejamento e a logística desenvolvidos pelas empresas para levar o gás de cozinha às mais distantes cidades por via fluvial, além das adaptações realizadas por moradores da região para o uso do gás em diversos equipamentos. Enfim, identifica-se o potencial de aumento do uso do gás na Amazônia para substituir, principalmente, o uso do diesel em diversas usinas térmicas espalhadas pela região, que atendem os sistemas isolados de geração de energia das pequenas cidades amazônicas.
La Amazonía en el pensamiento geopolítico brasileño
Authors: Padula Raphael , Brozoski Fernanda
Published: August 2024

Por su riqueza y posición geográfica, la Amazonía siempre ha estado presente en el pensamiento geopolítico brasileño. El presente artículo tiene como objetivo sistematizar sucintamente la evolución del pensamiento geopolítico brasileño con respecto a la Amazonía, mostrando cómo avanzó desde una perspectiva nacional hacia una mirada integradora sudamericana y cómo pasó a considerar otros actores en los análisis, dejando atrás un visón puramente estatal, pero que aún reconocía al Estado como el actor más relevante. El estudio procura señalar la importancia de la Amazonía para la relación entre los países sudamericanos desde el punto de vista estratégico y de desarrollo socioeconómico y destaca como la ocupación, integración y desarrollo de esa área son consideradas esenciales para apartar ambiciones externas. Para desarrollar esa propuesta, realizaremos una síntesis del pensamiento de cinco autores brasileños, utilizando al menos una obra de cada autor y sistematizando las producciones según tres períodos: la época de formación del pensamiento geopolítico brasileño en las décadas de 1920-1930, con Mário Travassos; el período de la Guerra Fría, con Golbery do Couto e Silva y Carlos de Meira Mattos; el período de la Posguerra Fría, con Therezinha de Castro y Bertha Becker. La estructura del artículo sigue el orden cronológico de los períodos señalados y el análisis se apoya en obras originales y, eventualmente, en producciones secundarias de especialistas sobre el tema.
From extractivism and illegalities to a circular bioeconomy in the Amazon Region
Authors: Denny Danielle Mendes Thame , Martins Michelle Márcia Viana , Burnquist Heloisa Lee
Published: August 2024

The Amazon is a vast region, but with many shortcomings. It presents one of the worst human development indicators in Brazil. This article shows that while the Amazon does not have an adequate policy to make the region economically viable, conservationist measures will be ineffective to protect the forest. A few responsible investments have not been sufficient to promote the region's economic development and there is an urgent need to preserve nature and increase the Amazon population's quality of life, eliminating deforestation and illegal extractive activities. It has been difficult to identify investments that bring real value in terms of sustainability to other options than extractive products. The analysis results showed how a combined effort between public and private initiatives is essential to increase the environmental social governance of companies that are doing business in global value chains, improve the institutional environment, catalyze sustainable measures to create a thriving sustainable circular bioeconomy in the Amazon region. To this end, this document addresses aspects related to responsible investments, circular bioeconomy, international markets, deforestation reduction, commodity production, land use regularization, and bioinputs extraction and cultivation.
A Conversão do TCA em OTCA e as dificuldades remanescentes
Authors: Filippi Eduardo Ernesto , Macedo Marcus Vinicius
Published: August 2024

Este artigo construiu uma narrativa histórica para analisar a conversão do Tratado de Cooperação Amazônica (TCA) em Organização do Tratado de Cooperação Amazônica (OTCA) e as dificuldades remanescentes enfrentadas pela instituição. A pesquisa tem caráter bibliográfico e documental, sendo classificada como longitudinal. Os principais eventos históricos perpassados pelo TCA até tornar-se OTCA envolvem as pretensões de internacionalização da Pan-Amazônia desde a Conferência de Estocolmo, o contexto da Guerra Fria, os avanços tecnológicos, o aprofundamento da globalização, as ditaduras militares e o processo de redemocratização que culminou no fortalecimento dos arranjos supranacionais. Todavia, o principal motivo dessa conversão deu-se pela tentativa de superação de dificuldades internas do bloco, tal como a percepção que sua configuração inicial pro tempore não contribuía para a integração de políticas na região, o que levou a uma reengenharia da instituição e adoção de uma secretaria permanente que, com mais autonomia, tem como função atual proteger os bens da natureza transnacional, conglomerados de nações, povos e diversidades integrados na Amazônia.

Published: August 2024

O debate sobre o desenvolvimento econômico na região Amazônica sempre foi uma questão delicada por envolver a complexidade, a biodiversidade, a potencialidade e, paradoxalmente, a fragilidade do bioma. Entretanto, a ocupação antrópica no Norte do continente sul-americano avançou ao longo do século XX, com projetos e propostas que urbanizaram e industrializaram polos regionais e, com a participação do Estado, como vetor de desenvolvimento da região. Com esse cenário, o meio ambiente sempre foi o grande ativo regional da América do Sul e, recentemente, palco de iniciativas de integração regional como a Iniciativa para a Integração da Infraestrutura Regional Sul-Americana (IIRSA), que representou em larga medida o grande projeto integracionista, ao longo da segunda metade da década de 2010, mudanças de calibre global alteram o escopo das decisões de Estados-nações, e, no fim de 2019, a pandemia de covid-19 mudou o mundo com 197 milhões de infectados e 4,2 milhões de mortos. Ainda assim, com a esperança trazida com as vacinas, os países ao redor do mundo têm orientado as balizas de ação e gestão para uma retomada econômica de baixo carbono e redução de utilização de combustíveis fósseis. Em paralelo a isso, as mudanças climáticas têm provocado cada vez mais eventos naturais extremos e fizeram com que a comunidade internacional voltasse as atenções para a América do Sul, com destaque para o Brasil, que desde 2019 tem adotado uma política ambiental desastrosa e errática. Com esse panorama, surgem experiências regionais, que intitularemos aqui de performance geoeconômica, que determinados espaços no continente, e no Brasil, podem incorporar a uma agenda de transição para uma economia de baixo carbono. Aqui apresentamos como esforço teórico-metodológico para compreensão das peculiaridades geoeconômicas e geopolíticas de governos subnacionais em desenhar e adotar políticas públicas (sociais, econômicas, territoriais e regionais) capazes de contribuir para as mudanças em curso no capitalismo contemporâneo que se reorganiza para retomada, mesmo com ameaças de novas variantes do SARS-CoV-2.

Published: August 2024

Quando se discute o término antecipado de contratos de concessão, a indenização pelos investimentos em bens reversíveis é uma questão central, que possui efeitos diretos sobre os interesses das partes. Por um lado, sem compensação economicamente justa, além de configurar possível ato de enriquecimento ilícito por parte da administração pública e empecilho à financiabilidade do projeto, o parceiro privado fica subjugado às ações do poder concedente e, como resultado, desencorajado a adimplir com as obrigações assumidas. Por outro lado, valores excessivos também prejudicam a melhor performance do concessionário no cumprimento dos investimentos, prazos e níveis de serviços acordados. Com o intuito de fomentar o debate sobre a “justa compensação”, este texto para discussão propõe metodologia para calcular a indenização na hipótese de extinção antecipada de concessões rodoviárias. O modelo sugere a limitação da compensação pelo valor economicamente recuperável do ativo, com a aplicação de regras de impairment em função dos níveis de tráfego simulados. Utilizando a teoria das opções reais, o trabalho avalia, em um estudo de caso, o valor adicionado pela flexibilidade de extinção prematura. Os resultados mostram que o método apresentado produz melhores resultados à execução contratual, uma vez que reduz os incentivos do concessionário e do poder concedente para interromper o contrato em relação ao modelo adotado pela legislação brasileira.
Influence of Process Parameters on Residual Stresses in Dissimilar Friction Stir Welding of Aluminum Alloys
Authors: Sarfaraz Zulqarnain , Aftab Saeed Hasan
Published: August 2024

Foreseeing how welded structures will behave requires careful consideration of the residual stresses that the friction stir welding (FSW) process introduces. These residual stresses can cause severe deformation and compromise the ability of friction stir welded structures to bear imposed external loads. This work uses a Sequentially Coupled Thermo-mechanical finite element simulation to quantitatively evaluate the influence of such residual stresses coming from the FSW process. This modelling method examines the thermal and post- weld stress distributions during the friction stir welding of dissimilar AA2024-T3 and AA5086-O alloys. The procedure entails an initial thermal analysis followed by a mechanical analysis to determine the distribution of residual stresses across the entire dissimilarly welded alloys. The study examined how alterations in FSW operational parameters, such as rotational and translational speeds, influence both the thermal conditions and residual stress distribution. The findings highlighted that both temperature and residual stress exhibited higher values on the retreating side of the specimen compared to the intended advancing side. As the tool rotational speed rose, the magnitude of longitudinal residual stress dropped, however it showed an increase with greater tool translational speeds. Moreover, the simulated outcomes demonstrate the substantial impact of welding fixtures on the profiles and magnitudes of residual stresses.

In recent years, the utilization of deep learning techniques for image classification has made significant strides in the field of agriculture. One of the key areas of interest in agriculture is the early detection and classification of diseases in crops, as this can have an insightful impact on crop revenue and quality. This research has investigated the influence of parallel computing on the performance of a deep learning-based classification model for diagnosing bean diseases. Specifically, we have explored the use of parallel computing frameworks to accelerate model training and inference, thereby enhancing the efficiency and effectiveness of disease classification. Our findings demonstrated the potential for parallel computing to accelerate model training. When training a bean disease classification model, we achieved an accuracy of 0.93 using parallel computing, compared to 0.83 with serial computing. Moreover, parallel computing significantly reduced training time, taking only 3 minutes compared to 51 minutes with serial computing.

Published: August 2024

Microplastics can be lethal to human health and the environment. Due to the increasing amount of microplastics in the environment, it is significant to access and determine the different methods and techniques to reduce and remove the microplastics in the environment, particularly in wastewater. This study has conducted a systematic review to analyze and identify what kinds of methods and techniques are suitable for the microplastic removal of domestic and municipal wastewater. The researchers utilized search engines and research databases, namely Google Scholar, Science Direct/ Elsevier, NCBI, and IWA Publishing, to look for and select the eligible literature related to this study. The eligibility criteria of the literature are as follows: clearly stated methods or techniques used in removing microplastics; mentioned the type of microplastics removed; specified wastewater source, either domestic or municipal wastewater; a quantitative scientific paper published between 2016 and 2024; original studies as full-text research or review articles that were published in English; and the studies can be studied in multiple countries. Only the stated eligibility criteria were considered; others not mentioned were excluded. Only 20 of the 134 studies that were downloaded and analyzed by the researchers were eligible for this systematic review. The result of the study showed that the best methods for removing microplastics in primary and secondary treatment are electrocoagulation, electro-flotation (EC/EF), and membrane filtration process (MFP) with 100% removal efficiency. Meanwhile, the most efficient method for tertiary treatment is the laboratory-scale sand filter, with up to 100% removal efficiency.
Of Rock Stars and Politics: Subjects of History in Ivan Jablonka’s
Goldman
Authors: BRACHER NATHAN
Published: August 2024

This article focuses on the historiographic questions posed—and answered—by Ivan Jablonka’s August 2023 historical biography of singer-songwriter-composer Jean-Jacques Goldman, and in particular on issues of subjectivity. On the one hand, Jablonka makes his own active presence as a historian visible and explicit in his narrative, thus continuing the historiography implemented in his books since publishing his
Histoire des grands-parents que je n’ai jamais eus
in 2012. On the other, his
Goldman
lays bare and analyzes the collective underpinnings that structure and inform what at first glance appears as individual, private experience. In the end, family stories prove to be prime subjects of history, while human subjectivity proves to be inextricably tied to configurations of historical evolution. Jablonka moreover demonstrates that, while long neglected and discounted by French historiography, popular culture clearly holds insights valuable for the intelligence of society and politics past and present.

Research suggests that girls’ initial interest in computer science tends to decline during their teenage years, a trend that is not observed among boys. This paper addresses this gender gap and proposes integrating programming into handicraft lessons to provide a creative activity for all students. The project was conducted in three Austrian schools over one year (2019–2020), involving 229 middle school students. The evaluation included questionnaires and the assessment of programmed and stitched designs to structure gender-sensitive workshops. While boys consistently reported higher scores than girls in interest, sense of belonging, and enjoyment, girls’ scores remained more stable. However, girls were significantly more likely to express pride in their final designs than boys, and overall, more girls completed individual designs as final products. These findings can be applied to interdisciplinary handicraft lessons in line with the Maker-Education movement to foster interest in programming.
Integration of AI and Metaheuristics in Educational Software: A Hybrid Approach to Exercise Generation
Authors: Láng Blanka , Dömsödi Balázs
Published: August 2024

This study explores the integration of generative artificial intelligence (AI) with Exercise Generation Algorithm+ (EGAL+), a multi-objective harmony search (HS) metaheuristic-based algorithm capable of composing high-quality exercises. These exercises are characterized by their diversity, consistent difficulty, and comprehensive coverage of the source material, tailored to user preferences. One of the main challenges of using metaheuristics to compile exercises efficiently is the initial creation of a large question bank, which often demands significant time and effort from instructors. To overcome this challenge, the integration of a readily available existing generative AI module is proposed. This module is accessed through its application programming interface, autonomously populating the question bank. This sets the stage for EGAL+ to fine-tune the selection and assembly of specific exams. The resulting program enables educators to create an extensive question bank from any educational material, independent of the subject, and subsequently compose exercises with minimal effort. This approach leverages the synergistic benefits of both generative AI and metaheuristicbased optimization, offering a robust and efficient solution for exercise generation.

Published: August 2024

O conceito de mecânica da fratura para previsão da capacidade resistente do concreto sob força axial de arrancamento dos pinos leva em consideração apenas a influência da projeção da área cônica e da resistência à tração do concreto; portanto, a precisão do modelo depende apenas do coeficiente de ajuste (k) do modelo, obtido experimentalmente. Este trabalho apresentou resultados experimentais da capacidade resistente de pinos isolados embutidos em blocos de concreto de fibra de aço para avaliar a precisão dos modelos empíricos da literatura. Os parâmetros estudados foram a espessura das cabeças dos pinos e as taxas volumétricas das fibras de aço. Os resultados experimentais mostraram ganhos de resistência em torno de 50% e 60%, respectivamente, para 0,5% e 1,0% de adição de fibra, para a resistência à compressão do concreto de 25 MPa e a espessura de cabeça th > 5,0 mm. A comparação com os modelos teóricos mostrou-se bastante conservadora, com valor de k inferior a 17, e mais precisa com a consideração do efeito da espessura da cabeça.

Published: August 2024

Project success is the primary goal of every construction project execution. The achievement of project success is influenced by who and how it is managed. Therefore, the leadership of the project manager significantly determines the quality of the construction project execution. Success is generally associated with the triple constraint criteria of being time, budget, and quality. Previous research states that the consequences arising from the application of an inappropriate leadership style can affects the performance of employees and will have an impact on smooth running construction project. So the aim of this research is to analyze the relationship and influence of the project manager's leadership style on the success of construction projects. The research involved employees from a large contractor company in Aceh. Data was collected through questionnaire distribution and analyzed using correlation methods with SPSS software. From the results of data analysis using product moment correlation, it was found that the leadership style variable as a whole has a significant relationship to the success of construction projects (Sig. < 0,05). The close relationship between the two is included in the moderate category, with a Pearson correlation value of 0,512.

Published: August 2024

The construction of the dam project poses a significant risk of workplace accidents, particularly due to the inherent dangers associated with large-scale construction. One such incident occurred at the Karaloe Dam site in South Sulawesi in 2019, resulting in the tragic death of a heavy equipment operator who fell from a height of 85 meters along with his machinery. This study aims to identify hazards and conduct a risk assessment of workplace accidents affecting construction, workers, communities, and the environment in the Main Dam Works of the Rukoh Dam Construction Project, Pidie Regency. The determination of hazards is qualitative, employing a case study approach through direct field observation. The Identification of Hazards Risk Assessment Determination of Risk Control and Opportunities (IBPRP) method is used, along with the determination of risk levels based on the risk matrix outlined in Minister of PUPR Regulation Number 10 of 2021. The analysis yielded 23 potential hazards, comprising 14 moderate-risk categories and 9 high-risk categories. However, following control measures such as engineering solutions, administrative protocols, and the utilization of personal protective equipment, the overall potential hazards have been mitigated to a low-risk level. The potential hazard with the highest risk level at the worksite is exposure to tire blowouts from heavy vehicles, specifically dump trucks.Keywords: Project Main Dam, Hazard Identification, Risk Assessment, Risk Level
Antigen-driven Convergent Evolution of Polysaccharide-specific “DH-less” B Cells in Glycoconjugate Immunized Mice
Authors: Kushwaha Sachin , Shome Pratiksha , Sehgal Devinder
Published: August 2024

Glycoconjugate vaccines elicit robust anti-polysaccharide Ab response by recruiting T-cell help. Multiple doses of glycoconjugate vaccine are required to induce long-lasting immunity. The characteristics of anti-polysaccharide Ab response have been reported previously. However, the effect of glycoconjugate booster immunization on anti-polysaccharide and anti–carrier protein Ab repertoire remains poorly understood. In this study, we used clinically relevant pneumococcal capsular polysaccharide type 14 (PCP14) conjugated with cross-reactive material 197 (CRM197) as a model glycoconjugate Ag (PCP14-CRM197). We performed a comprehensive sequence analysis of mouse mAbs generated against PCP14 and CRM197 following immunization with one or three doses of PCP14-CRM197. Analysis of the paired Ig H and L chain transcripts revealed that anti-PCP14 Ab repertoire is extremely restricted. The reoccurrence of five replacement mutations at identical positions in anti-polysaccharide mAbs generated from different mice provided evidence for Ag-driven selection in PCP14-specific B cells. Convergent evolution was observed wherein distinct V(D)J rearrangements resulted in identical or nearly identical CDR3 in anti-PCP14 mAbs. Abs that lacked DH encoded amino acids dominated the anti-PCP14 Ab response. In contrast, anti-CRM197 Ab response was quite diverse, with fewer mutations compared with the anti-PCP14 mAbs, suggesting that conjugation of the polysaccharide to a carrier protein interferes with the development of carrier protein–specific Ab responses. Our findings provide molecular insights into the maturation of Ab responses driven by booster doses of glycoconjugate. This has fundamental implications for the design of glycoconjugate vaccines, especially where the development of Ab response against the carrier protein is also crucial.
Mitochondrial DNA Programs Lactylation of cGAS to Induce IFN Responses in Patients with Systemic Lupus Erythematosus
Authors: Zhang Juan , Ji Huiyan , Liu Mengdi , Zheng Ming , Wen Zhenke , Shen Haili
Published: August 2024

Mitochondrial DNA (mtDNA) is frequently released from mitochondria, activating cGAS–STING signaling and inducing type I IFNs (IFN-Is) in systemic lupus erythematosus (SLE). Meanwhile, whether and how the glycolytic pathway was involved in such IFN-I responses in human SLE remain unclear. In this study, we found that monocytes from SLE patients exerted robust IFN-I generation and elevated level of cytosolic mtDNA. Transfection of mtDNA into THP-1 macrophages was efficient in inducing IFN-I responses, together with the strong glycolytic pathway that promoted lactate production, mimicking the SLE phenotype. Blockade of lactate generation abrogated such IFN-I responses and, vice versa, exogenous lactate enhanced the IFN-I generation. Mechanistically, lactate promoted the lactylation of cGAS, which inhibited its binding to E3 ubiquitination ligase MARCHF5, blocking cGAS degradation and leading to strong IFN-I responses. In accordance, targeting lactate generation alleviated disease development in humanized SLE chimeras. Collectively, cytosolic mtDNA drives metabolic adaption toward the glycolytic pathway, promoting lactylation of cGAS for licensing IFN-I responses in human SLE and thereby assigning the glycolytic pathway as a promising therapeutic target for SLE.

This study aimed to identify critical issues in artisanal bakery and pastry production in Italy that could improve food safety and quality. Fifteen voluntary Italian companies underwent on-site inspections and interviews from 2018 to 2021. The inspection concerned the production site characteristics, processing flows, materials, and personnel to pinpoint potential product contamination and record objective data collection through a 126-question demerit scoring system. The examined areas encompassed various aspects, such as the point of sale, management of raw materials and packaging, hygiene practices, finished product quality, sanitization procedures, external spaces, personnel, and other factors impacting food safety and hygiene. Additionally, assessments of the microbiological air quality were carried out. Two cohorts (six and nine companies in 2018-2019 and in 2020-2021, respectively) revealed critical issues in warehouse/packaging (70% non-compliance), finished product/cooling (50%), and people/products flow (38%). Site visits identified pest management and raw material handling challenges. Significant airborne mold and yeast contamination (30-50 colony-forming units/plate/h) was observed in areas near processing sites or with air turbulence. This study facilitated constructive discussions and proposed solutions with the participating companies.

The genome tagging project (GTP) plays a pivotal role in addressing a critical gap in the understanding of protein functions. Within this framework, we successfully generated a human influenza hemagglutinin-tagged sperm-specific protein 411 (HA-tagged Ssp411) mouse model. This model is instrumental in probing the expression and function of Ssp411. Our research revealed that Ssp411 is expressed in the round spermatids, elongating spermatids, elongated spermatids, and epididymal spermatozoa. The comprehensive examination of the distribution of Ssp411 in these germ cells offers new perspectives on its involvement in spermiogenesis. Nevertheless, rigorous further inquiry is imperative to elucidate the precise mechanistic underpinnings of these functions. Ssp411 is not detectable in metaphase II (MII) oocytes, zygotes, or 2-cell stage embryos, highlighting its intricate role in early embryonic development. These findings not only advance our understanding of the role of Ssp411 in reproductive physiology but also significantly contribute to the overarching goals of the GTP, fostering groundbreaking advancements in the fields of spermiogenesis and reproductive biology.
Exel–Pardo algebras with a twist

Takeshi Katsura associated a

-algebra

C^{\ast}_{A,B}

to a pair of square matrices

A\ge 0

and

B

of the same size with integral coefficients and gave sufficient conditions on

(A,B)

to be simple purely infinite (SPI). We call such a pair a KSPI pair. It follows from a result of Katsura that any separable

C^{\ast}

-algebra

\mathfrak{A}

which is a cone of a map

\xi:C(S^{1})^{n}\rightarrow C(S^{1})^{n}

in Kasparov’s triangulated category

KK

is

-isomorphic to

C^{\ast}_{A,B}

for some KSPI pair

(A,B)

. In this article, we introduce, for the data of a commutative ring

\ell

, non-necessarily square matrices

A

,

B

and a matrix

C

of the same size with coefficients in the group

\mathcal{U}(\ell)

of invertible elements, an

\ell

-algebra

\mathcal{O}_{A,B}^{C}

, the
twisted Katsura algebra
of the triple

(A,B,C)

. When

A

and

B

are square and

C

is trivial, we recover the Katsura

\ell

-algebra first considered by Enrique Pardo and Ruy Exel. We show that if

\ell

is a field of characteristic

0

and

(A,B)

is KSPI, then

\mathcal{O}_{A,B}^{C}

is SPI, and that any

\xi:\ell[t,t^{-1}]^{n}\rightarrow \ell[t,t^{-1}]^{n}

in the triangulated bivariant algebraic

K

-theory category

-isomorphic to

\mathcal{O}_{A,B}^{C}

for some

L(G,E,\phi)

associated to a group

G

acting on a directed graph

E

and a

\phi:G\times E^{1}\rightarrow G

. Similarly, twisted Katsura algebras are examples of the twisted Exel–Pardo

\ell

L(G,E,\phi_{c})

we introduce in the current article; they are associated to data

(G,E,\phi)

as above twisted by a

1

-cocycle

c:G\times E^{1}\rightarrow \mathcal{U}(\ell)

. The algebra

L(G,E,\phi_{c})

can be variously described by generators and relations, as a quotient of a twisted semigroup algebra, as a twisted Steinberg algebra, as a corner skew Laurent polynomial algebra, and as a universal localization of a tensor algebra. We use each of these guises of

L(G,E,\phi_{c})

to study its

K

-theoretic, regularity, and (purely infinite) simplicity properties. For example, we show that if

\ell

is a field of characteristic

0

,

G

and

E

are countable, and

E

is regular, then

L(G,E,\phi_{c})

is simple whenever the Exel–Pardo

C^{\ast}

-algebra

C^{\ast}(G,E,\phi)

is, and is SPI if in addition the Leavitt path algebra

L(E)

is SPI.

Published: August 2024

The membrane employed in microbial fuel cells (MFC) stands as a pivotal component, comprising more than half of the overall construction cost of the assembled MFC. This study introduces a novel earthen membrane, crafted by inclusion of wood ash in different weight ratios, providing a low-cost substitute to the conventional Nafion 117 membrane. Among the fabricated membranes, X3, engineered with red soil and 20% wood ash exhibits superior performance. The inclusion of wood ash enhances proton transport and mitigates oxygen diffusion into the anode, while also augmenting the ion exchange capacity of the fabricated membrane. The MFC equipped with the X3 membrane (MX3) demonstrates the highest COD removal (93.89±0.73%) and coulombic efficiency (66.10±2.53%). Notably, MX3 achieves a remarkable power density (Pmax: 1450.09±151.3 mW/m3), surpassing all other microbial fuel cells and marking a 9.8-fold increase in comparison to the control MFC. This study underscores the potential of the X3 membrane as a novel and economically viable alternate to Nafion 117 membrane.

Authors: Manahan Ian Jeffrey
Published: August 2024

Environmental pollution is the greatest problem in the world. The youth as future carriers have the most at stake to resolve this dilemma and take the lead together with other stakeholders to change this harmful trend. Qualitative research which employs key informant interviews, observation, and document analysis captures the various angles to describe the nature of the youth eco camp, analyze the changes in the environmental leadership and propose community organizing and action to support the youth eco camp.  NVIVO 14 was utilized to import the files, including the transcript of the KI responses, assist, and organize the coding of themes. The success of the youth eco camp is attributed to the collective effort and expertise of all stakeholders to achieve change and address environmental problems. The activities of the youth eco camp were able to develop and transform youth leaders’ environmental leadership which entails collaboration among people, empowerment, and inspiration that help youth leaders to become mentors and facilitators.  Basic steps, ethics, and principles of community organizing and action were presented to continuously support the environment-theme and leadership-inspired program.
