Authors: John William McCann  , Rebecca R Rogers  , Nicholas B. Washmuth
Published: July 2023

Background: Despite the growing popularity of bouldering, little is known about the degree and variabilityof muscle activation that occurs while solving bouldering problems. The purpose of this study was to explorethe electromyography of eight upper extremity and trunk muscles during a session of indoor bouldering whilecompleting four different problems.Methods: Eleven climbers with self-reported ability to climb a V-scale V4 problem grade or higher and regularlyboulder at least two days/week for at least six months participated in this study. Electromyography was used torecord muscle activity of the flexor digitorum superficialis, extensor carpi radialis longus, biceps brachii, tricepsbrachii, anterior deltoid, middle deltoid, posterior deltoid, and latissimus dorsi.Conclusion: The highest average EMG across all four climbs occurred in the flexor digitorum superficialis,latissimus dorsi, and extensor carpi radialis brevis. Significant differences in muscle activity were noted betweenthe anterior deltoid and latissimus dorsi, flexor digitorum superficialis and biceps brachii, triceps brachii andflexor digitorum superficialis, posterior deltoid and latissimus dorsi, and triceps brachii and latissimus dorsi.This information may be useful in developing a strength and conditioning program for

Authors: Sangeeta Appannavar  , Khan Shaheen Munir
Published: July 2023

Introduction: Pulmonary function tests such as spirometer and peak expiratory flow rate are the standard measuresto test lung volumes and capacities; but generally there is a lack of such equipment in emergency departments.Hence there is a need for an easier, quicker and convenient outcome measure in such set-ups. Single breath count(SBC) can be a simple assessment method in such clinical settings. However no studies for normal values of SBCin young Healthy adults were found during the search for literature.Objective: The objective of this study was to estimate normal value of SBC in Healthy young adult population.Results: 100 participants were enrolled from 18-24 years of age in the study. The mean SBC was 39(±7) and 41(±9)in females and males respectively. The SBC had a significant positive correlation with age at r=0.3, p value 0.0051and height at r=0.28, p value 0.0038. The SBC had a non-significant negative correlation with BMI and weight.Discussion: The results show that SBC was influenced significantly by gender (males>females), age and height ofthe individuals. However BMI and weight did not seem to influence the SBC.Conclusion: SBC is a test which is easy to perform and appears to correlate well with standard measures ofpulmonary functions. We estimated the normal values of SBC in young healthy adults which can be used in theclinical set up.

Authors: Golestanizadeh Mahboobeh , Sarvari Hadi , Chan Daniel W. M. , Banaitienė Nerija , Banaitis Audrius
Published: July 2023

In construction projects, managers make multiple decisions every day. Most of these decisions are relatively unimportant; some of them are critical and could lead to the success or failure of a construction project. To ensure construction companies make effective managerial decisions, decision making requires performing an initial technical and economic analysis, comparing different decision-making solutions, using a planning system, and ensuring project implementation based on the provided plans. Therefore, the use of powerful systems such as business intelligence (BI), which play a central role in management and decision-making, is essential in project-based companies. The current study aims to determine and evaluate the main managerial opportunities in the application of BI in project-based construction companies using a descriptive survey approach. An empirical research questionnaire consisting of 60 factors and 7 categories was adopted. The questionnaire, after confirming its validity and reliability, was distributed to 100 experts engaged in 5 active project-based construction companies who were familiar with BI topics. To analyse the data, a one-sample t-test and the Friedman test were performed using the SPSS software. The findings indicated that the importance of the identified opportunities for the use of BI in project-based construction companies is above average and that, in the case of using BI in such companies, these opportunities can be used to improve project performance. The results of the current study can help managers and other stakeholders as an effective decision-making tool to better implement BI in project-based companies.

AIM: The purpose of this study was to determine the difference in the effect of the learning approach, hitting distance, and kinesthetic perception on the ability of tennis groundstrokes.
METHODS: In conducting this research, researchers used an experimental method with a 2 × 2 × 2 factorial design. The research sample was 40 athletes with a purposive random sampling technique. The data collection technique used was a kinesthetic perception test and a tennis groundstroke ability test. The analysis technique used was Analysis of Variance at the significance level α = 0.05.
RESULTS: The results showed that (1) There is a significant difference in the effect of the learning approach on the groundstroke ability of tennis court with the calculated F value (Fo) = 4.941 greater than F table (Ft) = 3.26, (2) There is no significant difference between the fixed hitting distance and the gradual hitting distance on the ability of tennis groundstrokes with the calculated F value (Fo) = 2.196 which is smaller than F table (Ft) = 3.26, (3) There is a significant difference in the effect between  students  who have good kinesthetic perception and less kinesthetic perception on tennis groundstroke ability with the calculated F value (Fo) = 11.473 greater than F table (Ft) = 3.26, (4) There is no interaction between the learning approach and hitting distance on the ability of tennis groundstrokes with the calculated F value (Fo) = 3.238 which is smaller than F table (Ft) = 3.26, (5) There is no interaction between the learning approach and the kinesthetic perception of tennis groundstroke ability with the calculated F value (Fo) = 0.908 which is smaller than F table (Ft) = 3.26, (6) There is no interaction between hitting distance and kinesthetic perception on the ability of tennis groundstrokes with the calculated F value (Fo) = 2.868 which is smaller than F table (Ft) = 3.26, (7) There is an interaction between the learning approach, hitting distance, and students’ kinesthetic perceptions of the tennis groundstroke ability with the calculated F value (Fo) = 9.423 greater than F table (Ft) = 3.26.
CONCLUSION: Overall, there is an interaction between the three variables of the training model, meaning that the learning outcomes of the tennis groundstroke ability are obtained due to regular exercise. The achievement of the groundstroke ability of the tennis court due to the application of the learning approach is directly influenced by the difference between the distance and the difference in the student’s kinesthetic perception.
Extended suprametric spaces and Stone-type theorem

Published: July 2023

Extended suprametric spaces are defined, and the contraction principle is established using elementary properties of the greatest lower bound instead of the usual iteration procedure. Thereafter, some topological results and the Stone-type theorem are derived in terms of suprametric spaces. Also, we have shown that every suprametric space is metrizable. Further, we prove the existence of a solution of Ito-Doob type stochastic integral equations using our main fixed point theorem in extended suprametric spaces.

Citoyenneté et normalité
Authors: Liljeström Marianne
Published: July 2023

La notion de « citoyenneté sexuelle » est généralement utilisée pour parler spécifiquement des droits sexuels accordés ou refusés aux différents groupes. Cependant, cette notion peut aussi – dans le contexte d’un discours sur la citoyenneté qui défend la « normalité » d’être gay – être conceptualisée dans un sens beaucoup plus large et appliquée à la relation entre l’hétérosexualité et la pleine citoyenneté de manière plus détaillée. Cet article traite de la construction de la citoyenneté à travers les processus de normalisation, d’assimilation et d’intégration des sujets queer, en problématisant particulièrement la division conceptuelle entre le privé et le public. Ce texte avance finalement comme thèse que, dans les politiques queer – contrairement aux politiques d’identité gay et au lieu de normaliser la morale –, il s’agit de repenser la citoyenneté démocratique et de reconstruire la vie individuelle et collective en imaginant des corps, des soi et des intimités façonnés et organisés dans un ordre social non normalisant.
Exposer la loi. L’application de la loi norvégienne sur le recours aux services sexuels
Authors: Jahnsen Synnøve Økland
Published: July 2023

Depuis plus de vingt ans, et ce au niveau international, la lutte contre le trafic humain est devenue une question politique majeure. L’attention se portant principalement sur la prostitution et les différentes manières de la combattre, on pourrait dire que ce coup de projecteur a dans le même temps laissé dans l’ombre les autres formes de trafic humain. Cet article a pour but d’interroger « la pensée de modèles » qui caractérise les débats internationaux sur la prostitution et de poser un regard critique sur la formule nordique prétendument couronnée de succès que serait la pénalisation du recours aux services sexuels dans la lutte pour une société plus égalitaire. L’article décrit les changements récents dans les politiques norvégiennes en matière de prostitution et démontre que les mécanismes d’exclusion dans les États providence traditionnels poussent les ressortissants de pays étrangers vers les domaines de la politique pénale.
Gouverner la sexualité des couples : des cours pour les couples financés par l’état norvégien
Authors: Danielsen Hilde , Ludvigsen Kari , Mühleisen Wenche
Published: July 2023

Cet article se propose d’analyser la construction de la sexualité des couples norvégiens telle que la présente un cours mis en place et financé par l’État à l’intention des couples appelés à devenir parents pour la première fois. Intitulé « Bien vivre ensemble » (« Godt Samliv »), ce cours, lancé en 2005, est proposé gratuitement par les Centres de santé publique. De l’analyse des documents officiels, des débats politiques et des manuels utilisés pour cet enseignement, il ressort un discours sur la sexualité spécifiquement norvégien où l’accent est mis aussi bien sur l’égalité et la neutralité du genre que sur l’idée d’une démocratisation inclusive. Les jeunes parents sont encouragés à tout faire pour maintenir une relation durable et une vie sexuelle active permettant de favoriser le bien-être des enfants. L’idée de la sexualité qu’implique cette politique conjugale est fondée sur ce que l’on pourrait appeler « le devoir de spontanéité », lequel est présenté comme une tâche à laquelle les deux parents doivent s’atteler afin d’entretenir une relation stable et saine. À notre sens, cependant, telle qu’elle apparaît dans la politique gouvernementale sur la sexualité, cette rhétorique inclusive prônant la diversité a des limites, son discours excluant certaines formes d’intimité et de sexualité.
From Error Analysis to Effective Writing Outputs
Authors: Kurt Ali
Published: July 2023

This chapter investigates the overlap between error analysis, process-oriented writing, and a social constructivist approach to teaching and their effects on foreign language technical writing. The study is significant for its unique emphasis on the coalescence of these three domains, which is natural yet rare in research. Data collection tools included interviews, document analysis, and random participant observation. Error analysis was also used as a methodological approach to examine longitudinal data from a cohort of B1-level English language learners. The initial technical writing work revealed a failure to adopt the nature, structure, and content of technical writing. Yet, later-produced works exhibited better development over time after the interventions, which were full of specific strategies. By validating the synergy in error correction between process writing, which clears clouded minds with its precise step-by-step layout, and social constructivism, which helps generate meaning and cooperate, the study concludes the necessity of such integration into technical writing classes.
Determinants of Cryptocurrency Exchange Adoption
Authors: Illia Abdou , Lawson-Body Assion , Lee Simon , Akalin Gurkan I
Published: July 2023

Cryptocurrencies have become a global phenomenon, and the number of registered users of cryptocurrency exchange platforms has grown worldwide. However, only a small number of the registered users are active users that engage in actual transactions. In this study, the authors used a multi-theory approach to identify the key factors of the adoption of cryptocurrency exchanges and to develop a conceptual model that would have a potentially high explanatory power. The proposed model emphasizes the role of psychological innovation resistance, functional innovation resistance, technology readiness and trust, perceived risk and risk propensity, subjective norms, and critical mass of users. The authors discuss the model along with the research propositions it implies and the theoretical and practical implications of the study.

Published: July 2023

On-demand home service application (HSA) is a technological advancement that has brought various day-to-day services to our doorstep with just a few clicks. By using consumer-perceived values (utilitarian, hedonic, and social), trust transfer theory, and commitment-trust theory, the present study aims to investigate the factors influencing sharing intention and repurchase intention of consumers towards using HSAs on their mobile phones. This study involves collecting data from 357 respondents in India and analyzing the same using the SmartPLS 3 software. The results indicate that trust in HSA is influenced by utilitarian value and social value, but not by hedonic value. Trust in HSA results in repurchase intention, commitment, and sharing intention. Interestingly, trust in the user community affects sharing intention but not repurchase intention and commitment. The study integrates the consumer-perceived value, trust transfer theory, and commitment-trust theory to build an integrative framework that explains the consumers' sharing and repurchase intentions towards HSAs.
Bacillus Calmette-Guérin–Trained Macrophages Elicit a Protective Inflammatory Response against the Pathogenic Bacteria Brucella abortus
Authors: de Araujo Ana Carolina V S C , de Queiroz Nina M G P , Marinho Fábio V , Oliveira Sergio C
Published: July 2023

The bacillus Calmette-Guérin (BCG) can elicit enhanced innate immune responses against a wide range of infections, known as trained immunity. Brucella abortus is the causative agent of brucellosis, a debilitating disease that affects humans and animals. In this study, we demonstrate that C57BL/6 mouse bone marrow–derived macrophages under BCG training enhance inflammatory responses against B. abortus. BCG-trained macrophages showed increased MHC class II and CD40 expression on the cell surface and higher IL-6, IL-12, and IL-1β production. The increase in IL-1β secretion was accompanied by enhanced activation of canonical and noncanonical inflammasome platforms. We observed elevated caspase-11 expression and caspase-1 processing in BCG-trained macrophages in response to B. abortus compared with untrained cells. In addition, these BCG-trained cells showed higher NLRP3 expression after B. abortus infection. From a metabolic point of view, signaling through the Akt/mammalian target of rapamycin/S6 kinase pathway was also enhanced. In addition, BCG training resulted in higher inducible NO synthase expression and nitrite production, culminating in an improved macrophage-killing capacity against intracellular B. abortus. In vivo, we monitored a significant reduction in the bacterial burden in organs from BCG-trained C57BL/6 mice when compared with the untrained group. In addition, previous BCG immunization of RAG-1–deficient mice partially protects against Brucella infection, suggesting the important role of the innate immune compartment in this scenario. Furthermore, naive recipient mice that received BM transfer from BCG-trained donors showed greater resistance to B. abortus when compared with their untrained counterparts. These results demonstrate that BCG-induced trained immunity in mice results in better control of intracellular B. abortus in vivo and in vitro.

Published: July 2023

With the pursuit of extending the flight envelopes of helicopters towards higher cruise speed, helicopter manufacturers increasingly have come up with non-conventional configurations in recent years. Amongst these, Airbus Helicopters' RACER is a compound helicopter equipped with a boxwing and lateral pusher rotors. In combination with the main rotor, these additional components determine the aerodynamic characteristics of the helicopter. Thereby, depending on the flight conditions, their individual performance is influenced by a variety of interactions. As the understanding of these interactions is vital for the evaluation of the overall system, the respective mutual influence of main rotor, wings and lateral rotors is analysed in this paper for cruise flight. For this reason, high-fidelity coupled aerodynamic simulations are conducted not only for the full RACER configuration but also for reduced setups omitting individual components in order to isolate the effect of these components on the helicopter's aerodynamic performance.
Lichten Runner-up Paper: Semi-Empirical Modeling of Group 1 UAS Electric Powertrains
Authors:   Texas A&M University, Saemi Farid ,   US Army Research Lab, Beals Nathan , Benedict Moble
Published: July 2023

This paper describes the development of performance prediction models for the electric powertrains of group 1 unmanned aerial systems (G1UAS) that use sensorless brushless DC (BLDC) motor architecture consisting of a BLDC motor, electronic speed controller, and a battery. Per US Army definitions, G1UAS are platforms that weigh less than 20 lb. (9 kg). The resulting semi-empirical models for the motor, power electronics, and battery use high-level component specifications to enable pre-conceptual design space exploration and mission-based design optimization of G1UAS without a library of test data. The models also enable tradeoffs analysis between existing and/or conceptual designs without a series of flight tests. To develop, tune, and validate the models, a custom dynamometer test setup was designed and built to measure torque, speed, and electrical power data of small-scale motor drive systems. The validated models reveal that popular claims of high efficiency for electric powertrains are only valid in a narrow band of high speed/low torque operation. This is a critical finding for vehicle designers in the VTOL industry who are increasingly transitioning to electric powertrains in low speed/high torque applications which may decrease the overall system efficiency. A traditional rotor hover test stand was also developed to generate data with a traditional rotor load. The integrated motor and electronic speed controller model was able to predict the total efficiency of the hover stand tests within 5 percent of experimental values. The electrical models presented in this work can be immediately applied to design G1UAS given the torque and speed requirements of the rotors/propellers, the operating voltage of the vehicle system, and certain high-level component specifications for the motor, electronic speed controller, and battery. The models can also be used to BLDC powertrains for small terrestrial or aquatic electric vehicles.

Published: July 2023

Background: Physical activity is known to prevent several diseases and positively affect mental health. Previous studies have shown that smartphone addiction negatively affects the physical activity of children and adolescents. This study aimed to investigate the relationship between problematic smartphone use and physical activity among adolescents and the related factors using path analysis.Methods: Using data from the 16th Youth Risk Behavior Web-based Survey from 2020, scores on the Smartphone Addiction Scale—Short Version for Adolescents, physical activity, sex, socioeconomic status (SES), academic performance, depression, smoking, drinking, and sitting time were assessed. Complex sampling and path analyses were performed.Results: Of the total 54,948 students, 25.5% were smartphone risk users, including potential and high-risk users. The direct path coefficients of each factor indicated that female sex (-0.14 for male), low SES (-0.062), high academic performance (0.056), low sitting time for studying purposes (-0.033), high sitting time for non-studying purposes (0.071), and depressive mood (0.130) were related to problematic smartphone use (all P<0.001). Each factor affected problematic smartphone use, and subsequently had a negative effect on the amount of physical activity, with a direct path coefficient of -0.115 (P<0.001).Conclusion: In this study, we confirmed that problematic smartphone use among adolescents was negatively associated with performing an adequate amount of physical activity and that various factors, such as sex, SES, academic performance, and sitting time, directly and indirectly affected this relationship.

Materials and Methods: This is a retrospective analysis of patients with FA who underwent a matched-related donor HSCT.

Results: Sixty patients underwent 65 transplants between 1999-2021 using a fludarabine-based low-intensity conditioning regimen. The median age at transplant was 11 years (range: 3-37). Aplastic anemia (AA) was the underlying diagnosis in 55 (84.6%) while 8 (12.4%) had myelodysplastic syndrome (MDS) and 2 (3%) had acute myeloid leukemia (AML). The conditioning regimen used was fludarabine with low-dose cyclophosphamide for aplastic anemia and Fludarabine with low-dose busulfan for MDS/AML. Graft versus host disease (GVHD)prophylaxis consisted of cyclosporine and methotrexate. Peripheral blood stem cells was the predominant graft source (86.2%). Engraftment occurred in all but 1 patient. The median time to neutrophil and platelet engraftment was 13 days (range: 9-29) & 13 days (range: 5-31), respectively. Day 28 chimerism analysis showed complete chimerism in 75.4 % and mixed chimerism in 18.5%. Secondary graft failure was encountered in 7.7%. Grade II–IV acute GVHD occurred in 29.2% while Grade III-IV acute GVHD occurred in 9.2%. Chronic GVHD was seen in 58.5% and was limited in most patients. The median follow-up is 55 months [range: 2-144] & the 5-year estimated overall survival (OS) is 80.2 ± 5.1%. Secondary malignancies were noted in 4 patients. The 5-year OS was significantly higher in patients undergoing HSCT for AA (86.6 + 4.7%) as compared to MDS/AML (45.7+16.6%) (p= 0.001).

Conclusion: SCT using a fully matched donor provides good outcomes with low-intensity conditioning regimens in patients with FA who have an aplastic marrow.

Background:

There is an emergency need in discovering an efficient profile of molecular biomarkers for early diagnosis of Non-small cell lung cancer (NSCLC). Transcription factors as important groups of regulators that are able to adjust the cell cycles have attracted the attention of most researchers recently. NFATc2 and PPARG are two important factors that have been selected for this project to assess their potential for being a biomarker for NSCLC.

Materials and Methods:

Here in this study, 50 NSCLC patients were included. During bronchoscopy, which was their routine diagnostic approach, we collected tumoral and marginal normal tissues. After the extraction of the total RNA from the tissues, cDNA was synthesized, and the transcriptional level of NFATc2 and PPARG was examined by quantitative real-time PCR. Subsequently, the data were analyzed by proper statistical analyses.

Results:

The mRNA expression of NFATc2 and PPARG were down-regulated in biopsy tissues of NSCLC patients compared with their pair marginal tissues (Pvalues were 0.0011 and <0.0001 respectively). Moreover, both of them had significant AUC (area under the curve) in the ROC curve analysis (0.65 for NFATc2 and 0.81 for PPARG, Pvalue <0.05).

Conclusion:

It appears that mRNA expression of NFATc2 and PPARG possesses the potential to be regarded as a diagnostic or prognostic biomarker for NSCLC.

Obstructive jaundice (OJ) is a common problem in daily clinical practice. However, completely understanding the pathophysiological changes in OJ remains a challenge for planning current and future management. The effects of OJ are widespread, affecting the biliary tree, hepatic cells, liver function, and causing systemic complications. The lack of bile in the intestine, destruction of the intestinal mucosal barrier, and increased absorption of endotoxins can lead to endotoxemia, production of proinflammatory cytokines, and induce systemic inflammatory response syndrome, ultimately leading to multiple organ dysfunction syndrome. Proper management of OJ includes adequate water supply and electrolyte replacement, nutritional support, preventive antibiotics, pain relief, and itching relief. The surgical treatment of OJ depends on the cause, location, and severity of the obstruction. Biliary drainage, surgery, and endoscopic intervention are potential treatment options depending on the patient's condition. In addition to modern medical treatments, Traditional Chinese medicine may offer therapeutic benefits for OJ. A comprehensive search was conducted on PubMed for relevant articles published up to August 1970. This review discusses in detail the pathophysiological changes associated with OJ and presents effective strategies for managing the condition.

Published: July 2023

Metabolic-associated fatty liver disease (MAFLD) is one of the most common chronic liver diseases worldwide. In recent years, the occurrence rate of MAFLD has been on the rise, mainly due to lifestyle changes, high-calorie diets, and imbalanced dietary structures, thereby posing a threat to human health and creating heavy social and economic burdens. With the development of 16S sequencing and integrated multi-omics analysis, the role of the gut microbiota (GM) and its metabolites in MAFLD has been further recognized. The GM plays a role in digestion, energy metabolism, vitamin synthesis, the prevention of pathogenic bacteria colonisation, and immunoregulation. The gut-liver axis is one of the vital links between the GM and the liver. Toxic substances in the intestine can enter the liver through the portal vascular system when the intestinal barrier is severely damaged. The liver also influences the GM in various ways, such as bile acid circulation. The gut-liver axis is essential in maintaining the body’s normal physiological state and plays a role in the onset and prognosis of many diseases, including MAFLD. This article reviews the status of the GM and MAFLD and summarizes the GM characteristics in MAFLD. The relationship between the GM and MAFLD is discussed in terms of bile acid circulation, energy metabolism, micronutrients, and signalling pathways. Current MAFLD treatments targeting the GM are also listed.

The family home related to childhood and growing up is a model of culture and a fundamental matrix for shaping of human personality. In literature and the arts it makes an important point of reference in biographical and reminiscence-based narrations. All images from childhood are subject to diverse mechanisms of individual and collective memory and are used to work out certain events in the subconsciousness, thanks to the oneiric activity of the mind. The experiences from childhood should be interpreted taking into account the cultural images and patterns, e.g. a family home representing Arcadia, childhood as a land of happiness. From the psychological perspective, the elderly often come back to the time of childhood and show a tendency to reproduce the past events and writing memoirs. Particular events may be subjected to all kinds of transformations because of the subjective perspective, tendency to idealization and selective memory. spent her childhood in Russowo, school years in Kalisz, then she made her home in a Warsaw tenement house. Many times she visited the places she knew from her childhood, as documented in her Dzienniki. Her visits were of real character (travels to Kalisz), imaginary (when writing the novel Noce i dnie), of reminiscent character (a hot summer in Russowo), oneiric ones (during the war she dreamt of a full larder in Russowo), intuitive ones (she dreamt of coming back to her family home shortly before her death). Everything that has been left from her past life, transformed and confronted with reality, helps understanding her struggles and affections, her identity and helps making her biography.

A extração de minério de ferro no Brasil possui papel fundamental no desenvolvimento econômico e social, contribuindo com o sustento de diversas famílias em grande parte do território nacional. Entretanto, a indústria mineradora encontra problemas relacionados à gestão dos seus resíduos a fim de reduzir os impactos causados pelo acúmulo dos rejeitos provenientes dessa atividade. A fim de minimizar os impactos ambientais, sociais e econômicos causados pela atividade de mineração, este trabalho propõe o uso de rejeitos de minério de ferro para produção de concretos. O resíduo utilizado tem origem na atividade de mineração do estado de Minas Gerais, especificamente na barragem de rejeitos de Fundão, Mariana/MG. Para este trabalho, foram confeccionados concretos com relação água/cimento de 0,45 e 0,60, com adições de 0%, 5%, 10% e 15% de resíduo de beneficiamento de minério de ferro (RBMF). Foi avaliado a influência das adições do resíduo sobre a resistência mecânica dos concretos com os ensaios de resistência à tração por compressão diametral e resistência à compressão axial. No que se refere à resistência mecânica, as adições de 10% do RBMF, nos concretos com relação a/c = 0,45 e 0,60, apresentaram melhores resultados em relação às suas referências.
