Once-daily oral HIV pre-exposure prophylaxis (PrEP) is an effective strategy to prevent HIV, but is highly dependent on adherence. Men who have sex with men (MSM) who use substances face unique challenges maintaining PrEP adherence. Digital pill systems (DPS) allow for real-time adherence measurement through ingestible sensors. Integration of DPS technology with other digital health tools, such as digital phenotyping, may improve understanding of nonadherence triggers and development of personalized adherence interventions based on ingestion behavior. This study explored the willingness of MSM with substance use to share digital phenotypic data and interact with ancillary systems in the context of DPS-measured PrEP adherence. Adult MSM on PrEP with substance use were recruited through a social networking app. Participants were introduced to DPS technology and completed an assessment to measure willingness to participate in DPS-based PrEP adherence research, contribute digital phenotyping data, and interact with ancillary systems in the context of DPS-based research. Medical mistrust, daily worry about PrEP adherence, and substance use were also assessed. Participants who identified as cisgender male and were willing to participate in DPS-based research (N = 131) were included in this subsample analysis. Most were White (76.3%) and non-Hispanic (77.9%). Participants who reported daily PrEP adherence worry had 3.7 times greater odds (95% CI: 1.03, 13.4) of willingness to share biometric data via a wearable device paired to the DPS. Participants with daily PrEP adherence worry were more likely to be willing to share smartphone data (p = 0.006) and receive text messages surrounding their daily activities (p = 0.003), compared to those with less worry. MSM with substance use disorder, who worried about PrEP adherence, were willing to use DPS technology and share data required for digital phenotyping in the context of PrEP adherence measurement. Efforts to address medical mistrust can increase advantages of this technology for HIV prevention.
The dynamics of carbon emissions, energy, income, and life expectancy: Regional comparative analysis
Authors: Osei-Kusi Frank , Wu Cisheng , Tetteh Stephen , Castillo Wendy Irena Guerra
Published: February 2024

This paper examines the linear effects of economic growth on carbon emissions and their impact on mortality and morbidity rates in specific regions sub-Sahara Africa, Middle-East and North Africa, Europe and Central Asia (SSA, MENA, ECA). By analyzing longitudinal data for 82 panels over 30 years, we investigate the relationships between energy usage, per capita GDP, life expectancy, and carbon emissions. Our estimation results show positive correlations between energy use, carbon production, and life expectancy in both the combined sample and individual regions. However, death rate has a negative relationship with carbon production in the combined sample, MENA, and SSA regions. Per capita GDP positively influences carbon emissions and life expectancy in the combined sample and ECA, MENA, and SSA regions. We also identify asymmetric relationships between per capita GDP and carbon production, with evidence supporting the Environmental Kuznets Curve hypothesis for the combined and ECA samples, and an N-trajectory for SSA. These findings emphasize the importance of region-specific approaches to sustainable development, considering the unique environmental and economic challenges each region faces. Policymakers should consider our research insights when designing policies to mitigate the negative impacts of economic progress on the environment.
Reshaping the narrative: Tracing the historical trajectory of HIV/AIDS, gay men, and public health in Sweden
Authors: Nyman Fredrik
Published: February 2024

The human immunodeficiency virus (HIV) emerged as an endemic health crisis in the United States during the early 1980s. Initially labelled a “gay disease” due to its prevalence among gay men, the spread of HIV led to widespread fear and moral panic, as there was limited medical knowledge on preventing its transmission. While HIV is often associated with Sub-Saharan Africa, this article focuses on Sweden, a pioneering nation that became the first to achieve the remarkable Joint UNAIDS/WHO 90-90-90 continuum in addressing the epidemic. However, despite this significant milestone, the punitive legislation and attitudes prevalent in Sweden have had a counterproductive effect on curbing the virus’s spread. Drawing upon a comprehensive triangulation of various data and sources on the evolution of public policy in Sweden, this article argues for the urgent need to reduce stigma surrounding HIV and AIDS. By undertaking further measures to combat stigmatisation, we not only have the potential to prevent the spread of HIV but also significantly enhance the quality of life for individuals living with the virus. An essential step in this journey is to eliminate the legally-enforced mandatory disclosure of one’s HIV status, which would mark a tremendous victory for all those affected. With limited evidence to support the effectiveness of criminalisation and penal laws, no longer being viewed as criminals for non-disclosure would be a monumental achievement, positively transforming the lives of people living with HIV and fostering a more inclusive and supportive society.

Introduction

There are gaps in knowledge and experience of antiretroviral pre-exposure prophylaxis (PrEP) delivery in adolescents.

Methods

This pilot study enrolled Thai adolescents 14–20 year-old without HIV who reported risk behaviour. All participants were offered daily tenofovir/emtricitabine (TDF-FTC) and followed for 24 weeks. HIV testing, renal function, bone density scan, and sexually transmitted infection (STI) testing including syphilis serology and urine molecular testing for gonorrhoea and C. trachomatis were performed at baseline and weeks 12 and 24. Adherence was evaluated through intracellular tenofovir diphosphate (TFV-DP) levels in dried blood spots.

Results

Of the 61 enrolled adolescents, median age 18.1 (IQR: 14.8–20.9) years, 46 (75.4%) were males and 36 (59%) were MSM. Retention to week 24 was 80.3%. One third (36%) had TFV-DP levels consistent with taking ≥6 pills/week at week 12 and 29% at week 24. The factors associated with taking ≥6 pills/week were being MSM (adjusted odds ratio [aOR]: 53.2, 95% CI: 1.6–1811; p = 0.027), presence of STI at baseline (aOR: 9.4, 95% CI: 1.5–58.5; p = 0.016), and self-report of decreased condom use while taking PrEP (aOR: 8.7, 95% CI: 1.4–56.6; p = 0.023). 31% had an STI at baseline and this declined to 18% at week 24. No renal or bone toxicity was observed and there were no HIV seroconversions.

Conclusions

Daily oral PrEP with FTC-TDF in high-risk Thai adolescents is feasible, accepted, well-tolerated, and had no increased risk compensation; however, low adherence was a major challenge. Adolescent-specific PrEP strategies including long-acting modalities are needed for successful HIV prevention.
Negotiating spaces of fear in Tahar Ben Jelloun’s migrant writing
Authors: Ajah Richard , Atilade Kayode
Published: February 2024

This article examines how dystopic Moroccan urban societies generate a culture of fear that produces the fantasy of fleeing and how this fear sustains the dynamic acts of nomadism. It deploys postcolonial utopianism and psycholinguistics to study how Ben Jelloun’s ‘postmodern nomads’ and exilic subjects negotiate the spaces of fear in Labyrinthe des sentiments and Partir. The essay goes further to show how these psychosocially alienated characters use attitudinal lexemes to indexicate the fearful episodic memories of their original and foster loci. In both novels, repressed fear remains an essential catalysing element for the psycholinguistic construction of the utopian imagination for the desired spaces of Europe. Social dreaming is, nevertheless, the cord that binds illusion with reality and transforms the postcolonial subject’s fear into faith for a better tomorrow. The study concludes that Ben Jelloun’s migrant writing illustrates migrant and exilic subjects who negotiate all spaces of fear that are gendered, transcultural and transnational.

O estudo tem como objetivo analisar a formação dos estudantes dos cursos de Licenciatura do Instituto Federal do Amapá - campus Macapá (IFAP), buscando verificar se o mesmo contribui para o exercício do magistério na Educação Profissional (EP). A investigação tomou como referência os cursos de Licenciatura em Informática e Licenciatura em Química ofertados pela instituição, bem como os documentos oficiais norteadores. Utilizou-se na metodologia a abordagem qualitativa, a partir de um estudo de caso. Os resultados revelaram que as Licenciaturas ofertadas pelo IFAP são voltadas para o magistério na Educação Básica e não privilegiam a formação docente para a Educação Profissional, situação que contribui para um distanciamento entre propósitos educacionais históricos do lócus onde as mesmas são ofertadas e a preparação para o magistério na Educação Profissional Técnica, impedindo que essa relação seja percebida e vivenciada de forma dialógica no itinerário formativo dos estudantes das licenciaturas do IFAP.
Skeleton-based Human Activity Classification in Sparse Image Sequences
Authors: Kasprzak Wlodzimierz , Piwowarski Pawel
Published: February 2024

Research results on human activity classification in video are described, based on initial human skeleton estimation in video frames. Both single person actions and two-person interactions are considered. The initial skeleton data is estimated in selected video frames by OpenPose, HRNet or other dedicated library. Important contributions of presented work are computational steps of skeleton tracking and -refinement, and relational feature extraction from pairs of skeleton joints. It is shown, that this feature engineering significantly increases the classification accuracy. Regarding the final neural network encoder-classifier, two different architectures are designed and tested. The first solution is a lightweight MLP network, implementing the idea of a "mixture of pose experts". Several pose classifiers (experts) are trained independently on different time periods (snapshots) of single-person visual actions (or 2-person interactions), while the final classification is a time-related pooling of weighted expert classifications. All pose experts use the same deep encoding network. The second (middle weight) solution is based on a LSTM network.Both solutions are trained and tested on the action set of the well-known NTU RGB+D dataset, although only 2D data are used.Our results show comparable performance with some of the best reported STM- and CNN-based classifiers for this dataset. We conclude that by reducing the noise of skeleton data, highly successful lightweight- and midweight-approaches to visual activity recognition in image sequences can be achieved.
Singularity-Robust Inverse Kinematics for Serial Manipulators
Authors: Dulęba Ignacy
Published: February 2024

This paper is a practical~guideline how to analyze and evaluate literature algorithms of singularity-robust inverse kinematics or to construct new ones. Additive, multiplicative and based on the Singularity ValueDecomposition (SVD) methods are examined to retrieve well conditioning of a matrix to be inverted in the Newton algorithm of inverse kinematics. It is shown that singularity avoidance can be performedin two different, but equivalent, ways: either via properly modified manipulability matrix or not allowing to decreese the minimal singular value below a given threshold. It is discussed which method can always be used and which only when some pre-conditions are met. Selected methods are compared to with respect to the efficiency of coping with singularities based on a theoretical analysis as well as simulation results. Also some questions important for mathematically and/or practically oriented roboticians are stated and answered.

Influence of fiber types on the properties of the artificial cold-bonded lightweight aggregates
Authors: Sabr Hawraa Ahmed , Abbas Waleed A.
Published: February 2024

The cold-bonded pelletizing method is often employed in aggregate production since it uses less energy and helps reduce issues with gas emissions, contributing to economic and environmental benefits. In this study, fly ash was chosen as the raw material and used to partially replace cement in manufacturing artificial aggregate. Three types of fibers (polypropylene, polystyrene, and glass fiber) in different volume fractions were used to investigate their effect on the properties of the artificial cold-bonded lightweight aggregate. After the manufacturing process, aggregates were cured with a 28-day water curing. Their specific gravity, water absorption, density, impact value, and crushing value were tested to analyze the properties of the cold-bonded artificial aggregate. Results show that adding various volume fractions of PS, glass, and PP fibers during pelletization caused a more stable generation of aggregates with enhanced mechanical and physical properties.
The IgCAM BT-IgSF (IgSF11) Is Essential for Connexin43-Mediated Astrocyte–Astrocyte Coupling in Mice
Authors: Pelz Laura , Dossou Laura , Kompier Nine , Jüttner René , Siemonsmeier Gabrielle , Meyer Niklas , Lowenstein Elijah D. , Lahmann Ines , Kettenmann Helmut , Birchmeier Carmen , Rathjen Fritz G.
Published: February 2024

The type I transmembrane protein BT-IgSF is predominantly localized in the brain and testes. It belongs to the coxsackievirus and adenovirus receptor subgroup of Ig cell adhesion proteins, which are hypothesized to regulate connexin expression or localization. Here, we studied the putative link between BT-IgSF and connexins in astrocytes, ependymal cells, and neurons of the mouse. Global knock-out of BT-IgSF caused an increase in the clustering of connexin43 (Gja1), but not of connexin30 (Gjb6), on astrocytes and ependymal cells. Additionally, knock-out animals displayed reduced expression levels of connexin43 protein in the cortex and hippocampus. Importantly, analysis of biocytin spread in hippocampal or cortical slices from mature mice of either sex revealed a decrease in astrocytic cell–cell coupling in the absence of BT-IgSF. Blocking either protein biosynthesis or proteolysis showed that the lysosomal pathway increased connexin43 degradation in astrocytes. Localization of connexin43 in subcellular compartments was not impaired in astrocytes of BT-IgSF mutants. In contrast to connexin43, the localization and expression of connexin36 (Gjd2) on neurons were not affected by the absence of BT-IgSF. Overall, our data indicate that the IgCAM BT-IgSF is essential for correct gap junction–mediated astrocyte–astrocyte cell communication.
Social Sciences in the Arab World Special Collection: Introduction
Authors: Anderson Lisa , Salloukh Bassel
Published: February 2024

In the Middle East and North Africa, where most states have their origins in colonial regimes that supplied research for their own imperial purposes, the utility of university-based social research in informing public policy has never been uncontested. Continuing ambiguity about the status of the region and of its constituent units in global affairs both reflects and shapes the conduct of social science research. The absence of a widespread notion of the public, the public interest, or the public good as a reference for governments—the absence, in other words, of citizenship rights and democratic accountability—contributes to the confusion about the audience for the research that is conducted. This collection showcases novel interpretations and approaches that transcend persistent challenges to social research in the Middle East and North Africa

Concept and content of gender equality: legal aspect
Authors: Savetchuk N.M. , Pytliovana V.P.
Published: February 2024

The article studies the concept, essence, and content of gender equality as a legal category. Examples of definitions regarding the understanding of gender equality are provided. It was determined that Ukraine shares the gender principles regarding the establishment of equal rights and opportunities for women and men, declared in international documents. Today, gender equality is considered the main value of the third millennium, along with other values, such as justice, tolerance and freedom. A democratic society must provide equal opportunities for men and women to participate in all spheres of life. Therefore, it is imperative that gender discrimination be eliminated at the state level. It is recognized that effective regulation of gender relations is crucial for promoting gender equality, preventing gender discrimination, and ensuring equal participation of both genders in socially important decisions. This regulation also ensures equal opportunities for men and women in their professional duties and responsibilities. Today, gender equality is a crucial factor in a country’s development, and in the era of globalization, every society must address the issue of gender inequality.It has been established that gender equality is a fundamental component of the general principle of equality. This means that every individual should be treated equally, regardless of their gender. Gender equality, as a legal concept, encompasses the equal rights and opportunities for individuals of all genders, providing the same conditions for the realization of their potential, and affirming the fundamental rights of both women and men. It is emphasized that Ukraine has made some positive changes in terms of gender equality at a legislative level. However, there has been no significant progress in implementation, which has resulted in Ukraine receiving low international ratings regarding gender equality.

We have developed a simple model of the air permeability of paper and shown that it is in reasonable agreement with experimental results for softwood chemical pulps. The permeability is given as a function of ﬁbre external height and width and ﬁbre volume fraction including the lumen volume if present. The most important conclusion from the model is that the average ﬁbre thickness in the paper is the critical ﬁbre property controlling air permeability. In fact, the theory predicts that the sheet permeability is roughly proportional to the fourth power of the ﬁbre thickness.
The effect of constructivism-based science activities on young children s scientific inquiry process skills and self-directed learning ability
Authors:   Research Institute for Early Childhood Education - Korea National University of Education, Go Yu-ri
Published: February 2024

The purpose of this study was to examine the effect of constructivism-based science activities on the scientific inquiry process skills and self-directed learning ability of young children. The method used in this study to investigate the improvement of young children scientific inquiry ability was developed by Cho, Hong-Ja (2015). When looking into the self-directed learning activity level of young children, Hyun, Jeong-Sook s(1999) measuring instrument was used. This instrument revised and complemented Guglielmino s(1977) `self-directed learning readiness scale: SDLRS, 1977 . After consulting with an early childhood education expert and 4 graduate students majoring in early childhood education, the researchers revised this method before using it. The constructivism-based science activities were chosen following the standard of selection based on the references(Lee, Kyung-Woo, Cho, Boo-Kyung, Kim, Jeong-Jun 1999: Forman, Hill, 1984; Kamii, DeVries, 1993) and this experiment was conducted during a 11-week period from April 25, 2016 to July 8, 2016. To address the research questions, statistical data on mean and standard deviation for each group were obtained, and t-test was conducted after their pretest scores were subtracted from their posttest scores. The findings of the study were as follows: First, the experimental group that engaged in the constructivism-based science activities scored higher than the control group in scientific inquiry process skills, and the difference between the two was statistically significant(t=7.47, p<.05). Among the components of scientific inquiry process skills, the experimental group scored higher than the control group in observing(t=6.32, p<.05), measuring(t=3.58, p<.05), inferring (t=4.62, p<.05), predicting(t=4.54, p<.05) and communication ability(t=6.68, p<.05), and all the intergroup differences were statistically significant. But there was no statistically significant difference in classification skills. Second, the experimental group that engaged in the constructivism-based science activities scored higher than the control group in self-directed learning ability, and the difference between the two was statistically significant(t=7.02, p<.05). Among the components of scientific inquiry process skills, the experimental group scored higher than the control group in openness(t=3.38, p<.05), self-concept(t=5.63, p<.05), autonomy(t=3.15, p<.05), self-rating(t=3.53, p<.05), inner motive(t=3.76, p<.05), creativity(t=4.53, p<.05) and ability to solve problems(t=3.16, p<.05), and all the intergroup differences were statistically significant.

Communal register of monuments as an innominate form of conservator’s supervision
Authors: Sienkiewicz Tomasz
Published: February 2024

The view that the communal register of monuments constitutes an innominate form of conservator’s supervision results from the following observations. It is one of the grounds for the protection of a historical artefact contained in the register, mentioned, inter alia, in the decision on zoning development conditions (Article 19 section 1a item 2 of the Act on the protection and guardianship of monuments). With respect to artefacts included in the aforementioned register, decisions stipulated in Article 51 section 1 of the Act on planning and spatial development are subject to conservation agreements at the stage of proceedings to establish development conditions (Article 53 section 4 point 2 of the Act on spatial planning and development). In addition, with respect to buildings and areas not listed in the register of monuments, but included in the communal register of monuments, permission for the construction or demolition of a building structure is issued by the architectural and construction administration authority in agreement with the voivodeship conservator of monuments (Article 39 section 3 of the Construction Law Act). This legal situation in the light of the statutory aim of conservation supervision expressed, in accordance with Article 38 section 1 of the Act on the protection and guardianship of monuments, as monitoring the observance and application of the provisions on the protection and guardianship of monuments justifies the thesis of the article.
Impact of Import Substitution Policy on Domestic Chain Retail: New Reality
Authors: Fedotov Andrey
Published: February 2024

The recent geopolitical events related to the special military operation have caused a new wave of economic sanctions against Russia. Western sanctions were bound to affect the activity of the trade sphere, in particular, network retail. The response actions of the Russian Federation aimed at improving effectiveness of the import substitution policy are proving fruitful. In view of a new retail trade policy, the article examines some issues of import substitution in terms of filling the business niches vacated by former Western partners. It is indicated that many entrepreneurs in the field, previously unable to compete with foreign brands, have received an excellent opportunity to fulfill their own projects, among other things, by means of parallel imports. Having studied and analyzed the latest regulations and modern literature on the subject, the author proposes a hypothesis stating that the brand void left by Western companies after withdrawing from the Russian market should be effectively filled with domestic brands. With methods of statistical and factor analysis and based on the brand substitution strategy, a mechanism of applying the policy of import substitution in the field of domestic network retail is proposed.
Theoretical Aspects and Practical Significance of the “Minsky Moment” Under the Financial Crisis
Authors: Bubnov Vyacheslav , Abgaldaev Vladimir
Published: February 2024

The world economic crisis of 2007–2008 became a trigger in the search for a new understanding of instability. As a representative of monetary post-Keynesianism and the author of the financial instability hypothesis, H. Minsky showed that the financial system was precisely the reason for the cyclical nature of the economic crisis that reached its peak in its functioning so-called “Minsky moment”, after which the crisis was inevitably coming. Economic growth induces a sense of self-confidence among business entities and a desire for even more borrowing and lending, that provokes a systemic risk of high losses. The authors of this article used deductive and historical research methods, studied the financial crisis causes, taking into account high debt and risky operations on the financial markets that led to the financial system destabilization and destruction. It was revealed that business entities should take into account the “Minsky moment” in order to respond to the economic crisis in a timely manner, because financial instability would periodically generate next crisis, the course of which can become chronic.

Brazil is the world's third-largest maize producer. Its yield is influenced by climate, soil conditions, management and their interactions. Identifying the most suitable sowing window and using yield forecasting systems allows for increased yields and better harvest management. Crop simulation models can be used to assess crop responses to various conditions. This study aimed to identify the most favorable planting date for off-season maize by using the DSSAT CSM-CERES-Maize model for Jataí, Goiás state. Using meteorological data from 1986 to 2015, eight productivity forecasting strategies were tested. The results of the model application at different sowing dates indicated that the dates in January tended to present a more favorable attainable yield (Ya), i.e., values closer to the potential yield (Yp) of the crop, whereas in February, Ya were affected by lower precipitation from April to June. The best date for maize sowing was January 25th. The simulations indicated the possibility of predicting the off-season maize productivity in Jataí with high precision and accuracy up to 30 days prior to harvest (R² ≥ 0.81, d ≥ 0.90, and c ≥ 0.81).

BACKGROUND: The microbiome of the gastrointestinal tract ensures colonization resistance of the intestinal epithelium, produces enzymes, and participates in nutrient metabolism. Changes in its composition lead to pathological conditions of the intestines.AIM: To determine the structure of the incidence of acute intestinal infections in children living in the Southern Aral Sea region and to characterize the effect of bioimmune correction of changes in the intestinal microbiome in children with shigellosis.
MATERIAL AND METHODS: In the period from 06.07.2020 to 05.10.2020, 179 children with intestinal infections aged 2 to 7 years living in an environmentally unfavorable zone of Southern Uzbekistan were examined. The children were divided into two groups: the first (32 children) received basic therapy (pathogenetic therapy, antibiotic therapy, diet), the second (11 children) received basic therapy with bioimmune correction with bifidobacteria bifidum (bifidumbacterin PL) and thymus peptides of sheep embryos and newborn lambs (immunomodulin). To characterize the microbiome, the material was screened on differential diagnostic media, identifying obligate, facultative and opportunistic microflora. To assess the statistical significance of differences between data groups, the Student's t test was used, taking p ≤0.05 as a significant level.
RESULTS: Shigellosis was diagnosed in 43 sick children (24% of those examined), escherichiosis was diagnosed in 34 (19%), salmonellosis was diagnosed in 30 (16.3%), and diarrhea of other bacterial etiology was diagnosed in 23 (13%) patients. In all variants, changes in the intestinal microbiome were detected. Etiotropic therapy led to an improvement in the general condition of patients, but did not affect dysbiotic changes in the intestines and did not contribute to the restoration of the microbiome. Bioimmune correction of dysbiosis in shigellosis in 11 patients using preparations of bifidobacteria bifidum and fetal thymic peptides led to the restoration of intestinal microflora to normal values: the number of lactose-negative E. coli significantly decreased by more than 5 orders of magnitude (p=0.037), fungi of the genus Candida (p=0.030) and enterococci (p=0.019) by 3 orders of magnitude, and staphylococci by 2 orders of magnitude (p=0.048).
CONCLUSION: The use of preparations of bifidobacteria bifidum and fetal thymus peptides as bioimmunocorrectors is a promising therapeutic strategy for shigellosis in children.
Optimal Distributed Generation Placement and Economic Analysis for Enhancing the Active Radial Distribution System using BPSO

Published: February 2024

Dispersed generation (DG) are known to improve the reliability of electrical grids. However, to maximize their benefits, it’s essential to ensure that DG units are optimally sized and positioned. Poor placement can have adverse effects on power grids, causing voltage profile degradation and an increase in power loss. Various methods have been recommended to determine the best size and location for DG units. This article focuses on establishing a technique for optimal scheduling and operation of DG units to reduce power-loss, improve voltage contour, and enhance network reliability. The Binary particle swarm optimization (BPSO) artificial intelligence method is implemented to find the optimal node and DG size. The applicability of BPSO is demonstrated using the IEEE 33 distribution system with Typ-1 DG, with results compared with other methods. The evidence clearly demonstrates that BPSO reigns supreme over all other methods.

Dalam campuran mortar, jumlah pasir yang dibutuhkan kira-kira tiga kali lipat jumlah semen yang digunakan. Oleh karena itu, permintaan pasir alam sangat tinggi karena pesatnya pertumbuhan infrastruktur saat ini. Akibatnya, penambangan pasir yang berlebihan telah menyebabkan erosi sungai yang berlebihan dan bahaya lingkungan. Hal ini menyebabkan perlunya mencari bahan alternatif pengganti pasir. Berkaitan dengan hal tersebut, penelitian ini dilakukan untuk mengetahui kinerja mortar dengan limbah peledakan sebagai material pengganti pasir. Limbah peledakan adalah limbah bahan peledak yang berasal dari area pembuatan kapal atau perawatan di anjungan angkut dan operasi militer. Persentase penggantian limbah peledakan terpilih adalah 0%, 10%, 20%, 30%, 40% dan 50%. Hasil penelitian menunjukkan bahwa persentase limbah peledakan yang dapat digunakan sebagai pengganti pasir mencapai 50%, dengan kuat tekan 21.8Mpa yang hampir dua kali lipat nilai sampel kontrol sebesar 14.2Mpa. Di sisi lain, tingkat penyerapan air untuk sampel 50.0% adalah 9.0%, lebih rendah dari nilai mortar kontrol sebesar 9.2%. Sesuai dengan ASTM C1329, kekuatan tekan mortar yang menggunakan limbah peledakan memenuhi kekuatan yang diijinkan untuk struktur.In a mortar mixture, the amount of sand needed is about three times the amount of cement used. Therefore, the demand for natural sand is extremely high due to the rapid growth of infrastructure these days. As a result, the over-mining of sand has caused excessive river erosion and environmental hazards. This has led to the need of finding an alternative material to replace sand. In this regard, this study was conducted to investigate the performance of mortar with blasting waste as a replacement material for sand. Blasting waste is explosive waste from shipbuilding areas or maintenance on transport bridges and military operations. The replacement percentages of blasting waste selected were 0%, 10%, 20%, 30%, 40% and 50%. The result showed that the percentage of blasting waste that can be used as a replacement for the sand is up to 50%, with a compressive strength of 21.8Mpa which was almost double the value of the control sample at 14.2Mpa. On the other hand, the water absorption rate for the 50.0% sample was 9.0%, lower than the value of the control mortar at 9.2%. In accordance with the ASTM C1329, the compressive strength of the mortar using blasting waste complied with the allowable strength for structures.

A Honra e o Brio militar: uma categoria de análise na formação do discurso na imprensa militar do Oitocentos
Authors: De Santos Nascimento Fernanda
Published: February 2024

A partir dos anos 1850 observa-se a ocorrência de muitos periódicos militares na imprensa nacional. Tais periódicos escritos por militares e voltados para o público militar acompanham as tendências de profissionalização das forças armadas nacionais que começam a ocorrer no século XIX, como consequência do desenvolvimento do moderno estado nação. No Brasil, os periódicos servem para afirmar, de forma categórica, um discurso positivo sobre o que é ser militar neste período. Na falta de um discurso institucional oficial, a construção discursiva institucional paira nas mãos de oficiais comuns, que utilizam a imprensa como canal de comunicação para expor suas ideias sobre o metier militar e suas atribuições.  Neste sentido, o objetivo deste artigo é apresentar a honra e o brio militar, como importantes características atribuídas ao ser militar no século XIX, de acordo com os redatores e colaboradores dos periódicos militares publicados no período.
