More on 1QSamuel and the Theory of Literary Growth. Response to Benjamin Ziemer
Authors: Elgvin Torleif
Published: March 2021

There is no space in the innermost part of the 1QSam scroll to include 2Sam 24. The last three columns (2Sam 20–23) can be materially reconstructed with 46, 42, or 21 lines. With one of the eight literary appendices to 2Samuel missing, other appendices may be absent too. A number of factors point to a reconstruction with 21 lines and containing only three appendices: a) very few scrolls dated to 50–1 BCE have more than 40 lines, medium-sized scrolls are most common; b) a 46-line reconstruction without ch. 24 would destroy the chiastic structure of the appendices; c) a 46-line reconstruction (as preferred by Ziemer) would require the long psalm of ch. 22 to be formatted without any section breaks or vacats; d) Qumran scrolls and literary analysis evince many cases of 2nd and 1st century literary editing of biblical scrolls as well as preservation of earlier variant recensions. Further, Ziemer’s consequent critique of the linear model of literary growth in biblical studies should be welcomed but remains one-sided. Editorial growth into new recensions could develop according to different paradigms.
Full-Scale Testing of Flowable Cementitious Materials for Rapid Pavement Repair
Authors: Carruth William D. , Edwards Lulu , Tingle Jeb S. , Howard Isaac L.
Published: March 2021

Flowable technologies that make use of hydraulic cements are relied upon in many ways for infrastructure, operations, and contingency activities. The primary objective of this paper is to report full-scale performance findings from testing of rapid-setting flowable fill (RSFF) as an expedient pavement repair technology in hot and cold climates. The scenarios explored were hot climates where RSFF was used as the surface of the repair and directly trafficked by an aircraft simulator load cart and cold climates where RSFF was used as an expedient backfill underneath a rapid-setting concrete (RSC) cap. Twelve expedient pavement repairs were investigated in this study. The data collected showed that RSFF is capable of being used as an expedient repair surface in hot weather and as a high-quality backfill in cold weather. All repairs withstood 112 passes of an aircraft load cart after approximately 2 hours of cure time, thus demonstrating the viability of RSFF as a temporary surface in hot weather conditions and as a backfill material with an RSC cap in cold weather conditions. Aluminum sulfate was tested as an accelerating admixture for cold weather conditions, but it did not perform well. The most efficient manner of using RSFF in cold weather was to heat the mix water.
Effectiveness of Hydrated Lime Filler on Fracture and Cracking Properties of Polymer and Crumb Rubber–Modified Asphalt Mastics
Authors: Singh Dharamveer , Das Aditya Kumar , Habal Ayyanna , Bhonsle Shreyanshu
Published: March 2021

This study evaluates fracture and toughness behavior of different types of mastics prepared using polymer-modified asphalt (PMA) and crumb rubber–modified asphalt (CRMA), in combination with basalt (B) and hydrated lime (HL) fillers. The asphalt mastics were prepared for filler to binder (F/B) ratio of 0.6 and 1.0. For F/B = 0.6, 2 combinations of mastic, namely, B = 60 % and HL = 0 % and B = 40 % and HL = 20 %, were prepared using PMA and CRMA asphalt binders. Likewise, for F/B = 1, 2 combinations of mastic, namely, B = 100 % and HL = 0 % and B = 80 % and HL = 20 %, were prepared using PMA and CRMA asphalt binders. Therefore, four different asphaltic mastic were prepared for PMA and CRMA to understand performance of asphalt mastic with and without HL in combination with B fillers. The fracture and toughness behavior of asphalt mastic was investigated using double-edge-notched tension (DENT) and force ductility (FD) test, respectively. The overall test results infer that, in addition to nature of fillers, filler quantity and type of binders have significant impact on the fracture and toughness potential of asphalt mastic at intermediate and sub-intermediate temperature. The DENT test results indicate that the inclusion of HL had an effective contribution in enhancing the fracture resistance of base PMA mastic prepared with low F/B ratio (0.6), whereas the addition of HL filler did not show improvement in the fracture resistance potential of the base CRMA mastic. Similarly, the toughness ratio signifies that the cracking resistance potential of PMA and CRMA mastics can be improved with the addition of HL filler irrespective of F/B ratio.

In a series of decisions issued during his last two years on the bench, Judge Jack B. Weinstein of the Eastern District of New York set out a new vision for the imposition and termination of federal supervised release. Specifically, beginning with his decision in U.S. v. Trotter in 2018, he focused on imposing shorter terms, terminating supervised release early, and vowed not to return people to prison for supervised release violations caused by habitual alcohol or marijuana use. This article examines Judge Weinstein’s jurisprudence on supervised release and looks at the impact of his new vision. After reviewing Judge Weinstein’s pre-Trotter supervised release cases, it examines the Trotter case and his subsequent supervised release decisions. The article concludes by reviewing the impact of these decisions on the imposition of supervised release in the Eastern District as well as the wider federal criminal legal system.
Disco Before Disco
Authors: Stratton Jon
Published: March 2021

Dancing has been a central component of the experience of popular music, yet with the exceptions of disco and electronic dance music, it is rarely discussed in the academic literature. This article focuses on a pivotal moment in the transformation of dancing to popular music in England. The second half of the 1960s saw the gradual move from dancing to live groups to dancing to records in clubs. Just before this dancing itself had changed from something done by couples to something done by individuals albeit usually in pairs, though often girls might dance together in a group. Young people in England learned to dance to music with a strongly emphasized beat. This article traces this genre from its early manifestations in tracks by the Honeycombs and the Dave Clark Five in the first half of the 1960s to the early 1970s in tracks by Mud and Slade. The article ends by looking at how this musical genre morphed into Eurodisco in the production work of Giorgio Moroder.
Reconstructed Nostalgia
Authors: Ballam-Cross Paul
Published: March 2021

In chillwave, synthwave, vaporwave, and their respective subgenres, a common element is the thread of nostalgia, constant in each. This is the case for both the cover art used for these releases, as well as compositional techniques used in the music itself. Although these genres certainly approach nostalgia in different ways, they each rely on imagery that evokes nostalgic feelings or memories in a form of collective, imaginative self-soothing. The memories evoked, however, tend to rely on unrealistic depictions of reality and center on times and places that have perhaps only existed in the listener’s imagination.

This article argues that the re-interpretation of cultural memory is an important structural feature in chillwave, synthwave, vaporwave, and vaporwave subgenres such as mallsoft and the associated Japanese “city pop” revival. Through a discussion of the visual and musical connections that draw these genres together, the concepts of nostalgia in music (as well as the related concept of “reconstructed nostalgia”) are explored. An examination of listeners’ narrative explorations of these genres posted online suggests that users engage knowingly and willingly with this “reconstructed nostalgia.” Ultimately, this forms a collaborative and collective universe used by listeners as a method of escapism, through both their own imaginations and online comments.

Published: March 2021

Introduction

Autosomal recessive forms of pseudohypoaldosteronism are caused by genetic defects in the epithelial sodium channel. Little is known about the long-term outcome and medication needs during childhood and adolescence.

Objective

This study reports a single-centre experience of children affected with this ultra-rare condition over a 37-year period.

Methods

We report the clinical presentation, growth, neuro-development, associated conditions, mortality and medication dosing and administration for 12 affected children from eight families.

Results

All children were presented within the first 2 weeks of life with life-threatening, severe hyperkalaemia and hyponatraemia. All parents were consanguineous and of South Asian, Middle Eastern or African ethnic origin. Eight children had homozygous mutations in the SCNN1A and SCNN1G genes, encoding the epithelial sodium channel subunits alpha and gamma, respectively, including one novel mutation. Three children died (25%) and two (16%) had severe neurological impairment post-cardiac arrest secondary to hyperkalaemia. One affected female had a successful pregnancy at the age of 28 years.

Conclusion

Despite high mortality and morbidity in this condition, survival with normal physical and neurological outcome is possible, justifying intensive management to prevent electrolyte imbalance.

Objective

Testosterone is a critical determinant of health in both genders. However, the relationship between circulating levels of testosterone and mortality remains undetermined.

Methods

We examined the associations of serum total testosterone (TT) and free testosterone (FT) with all-cause and cause-specific mortality in 154 965 men and 93 314 postmenopausal women from UK Biobank. Cox regression models were used to calculate the hazard ratios (HR) and 95% CIs. Given multiple testing, P < 0.005 was considered statistically significant.

Results

Over a median follow-up of 8.9 (inter-quartile range: 8.3–9.5) years, we documented 5754 deaths in men, including 1243 (21.6%) from CVD and 2987 (51.9%) from cancer. In postmenopausal women, 2435 deaths occurred, including 346 (14.2%) from CVD and 1583 (65.0%) from cancer. TT and FT concentrations were inversely associated with all-cause mortality in men, with the multivariable HR of 0.82 (95% CI: 0.75–0.91) and 0.80 (95% CI: 0.73–0.87) for the highest (Q5) vs the lowest quintile (Q1), respectively. In postmenopausal women, TT concentrations showed a positive association with all-cause mortality (HR for Q5 vs Q1 = 1.20, 95% CI: 1.06–1.37). Furthermore, higher TT and FT concentrations were associated with a lower risk of cancer mortality in men (both P for trend = 0.001), whereas TT concentrations were suggestively associated with a higher risk of cancer mortality in postmenopausal women (P for trend = 0.03).

Conclusions

Our findings suggest that high levels of circulating testosterone may be beneficial for all-cause and cancer mortality in men but detrimental in postmenopausal women.

I connettivi perché e weil come introduttori di enunciati autonomi nei giornali di oggi
Authors: Rosi Benedetta
Published: March 2021

The aim of this paper is, first of all, to outline the contemporary uses of causal structures in Italian writing, focusing on some less canonical syntactic and textual manifestations. These non-prototypical constructs will be, then, compared with the corresponding ones in German. The analysis that will be presented are based on qualitative and quantitative data derived from corpora of Italian and German newspaper writing. As far as the Italian language, the paper will focus on the causal connective perché: after presenting its frequency of use compared to the other causal connectives, we will discuss some of its most common syntactic and informative-textual configurations, with particular reference to the case in which perché introduces an independent utterance, preceded by a strong punctuation mark. Right this last use will be observed also in German newspapers, thanks to a preliminary survey that will focus on the causal connective weil. For both languages we will consider the frequency of this peculiar use, as well as its possible forms and textual functions, in order to highlight analogies and differences between German and Italian.

Seaweed bio-composite films with different proportion of Lemang and Semantan bamboo microcrystalline cellulose (MCC) were fabricated via solvent casting. The seaweed/MCC composite films were flexible, transparent, and slightly yellow. The MCC particles further enhanced mechanical properties and opacity of films. The thermal stability of seaweed films was moderately improved upon addition of bamboo MCC particles. Bamboo MCC was found to be comparable to commercial MCC in reducing the water vapor permeability (WVP), water solubility (WS), and moisture absorption capacity (MSC) of seaweed films. The tensile strength (TS) of seaweed films was increased by 20 to 23% with addition of up to 5% MCC particles. In addition, bamboo MCC efficiently reduced the WVP of seaweed films comparable to commercial MCC particles. The WS of seaweed films was decreased by 10 to 19% with addition of 1% MCC particles loading. Lemang bamboo MCC (SB-MCC) was remarkably reduced the moisture absorption capacity (MAC) of films up to 25% with inclusion of only 1% MCC. Morphological analysis via Scanning Electron Microscopy (SEM) confirmed that there was homogeneous dispersion of MCC particles in the films. MCC particles improved the mechanical, thermal, and optical properties of seaweed films making them more suitable for food packaging applications.

Timber structures in marine applications are often exposed to severe degradation conditions caused by mechanical loads and wood-degrading organisms. This paper presents the use of timber in marine environments in Europe from a wood protection perspective. It discusses the use of wood in coastline protection and archeological marine wood, reviews the marine borer taxa in European waters, and gives an overview of potential solutions for protection of timber in marine environments. Information was compiled from the most relevant literature sources with an emphasis on new wood protection methods; the need for research and potential solutions are discussed. Traditionally, timber has been extensively utilized in a variety of marine applications. Although there is a strong need for developing new protection systems for timber in marine applications, the research in this field has been scarce for many years. New attempts to protect timber used in marine environments in Europe have mainly focused on wood modification and the use of mechanical barriers to prevent colonization of marine wood borers. The importance of understanding the mechanisms of settlement, migration, boring, and digestion of the degrading organisms is key for developing effective systems for protecting timber in marine environments.

Published: March 2021

The residual peels of andiroba seeds were submitted to alkaline pretreatment that aimed to maximize the recovery of fermented sugar. Evaluation of the best operation performance via the reaction time variables (20, 60, and 100 min), NaOH concentration (2, 3, and 4% (m/v)), and temperature (60, 90, and 120 °C) at a fixed solids concentration of 5% (m/v) was performed. A Box-Behnken experimental design was used. Lignocellulosic material was characterized by cellulose (30.57 ± 1.00%), hemicellulose (15.08 ± 0.65%), lignin (36.02 ± 1.05%), extractives (7.49 ± 0.03%), and ash (1.53 ± 0.28%). The optimization was performed using the response surface methodology approach. The model provided a coefficient of determination (R2) of 0.95. The predicted optimal conditions for the process were a reaction time of 100 min, NaOH concentration of 4% (m/v), and temperature of 120 °C, which allowed the authors to obtain a saccharification of approximately 47.9%.

Published: March 2021

The remediation effects of peanut shell biochar (HBC) and Mg-modified peanut shell biochar (MHBC) prepared under pyrolysis temperatures of 300 °C and 600 °C on Cd2+ polluted brown soil were investigated in a pot experiment. The results showed that the biochar treatment increased soil pH and decreased the bioavailable Cd2+ content in the soil. Compared with the control treatment (CK), the pH value increased by 0.32 to 2.5 upon treatment with 1% and 2% of HBC and MHBC. Bioavailable Cd2+ in the soil decreased by 5.64% to 21.33% with HBC. The MHBC presented better amendment effects than HBC; bioavailable Cd2+ in the soil decreased by 26.2% to 50.1% with the addition of MHBC. The addition of HBC and MHBC increased the shoot height and decreased the root length of the spinach. Moreover, they significantly decreased the accumulation of Cd2+ in the shoots and roots of the spinach. Compared to CK, the Cd2+ content in the shoots decreased by 7.0% to 46.8% upon treatment with 1% and 2% of HBC and MHBC, while the Cd2+ content in the roots decreased by 7.3% to 52.7%. The Cd2+ content in the shoots and roots was more greatly decreased with MHBC than with HBC.

Published: March 2021

BACKGROUND:

In South Africa, tuberculosis (TB) is a leading cause of death among those <20 years of age. We describe changes in TB mortality among children and adolescents in South Africa over a 13-year period, identify risk factors for mortality, and estimate excess TB-related mortality.

METHODS:

Retrospective analysis of all patients <20 years of age routinely recorded in the national electronic drug-susceptible TB treatment register (2004–2016). We developed a multivariable Cox regression model for predictors of mortality and used estimates of mortality among the general population to calculate standardized mortality ratios (SMRs).

RESULTS:

Between 2004 and 2016, 729 463 children and adolescents were recorded on TB treatment; 84.0% had treatment outcomes and 2.5% (18 539) died during TB treatment. The case fatality ratio decreased from 3.3% in 2007 to 1.9% in 2016. In the multivariable Cox regression model, ages 0 to 4, 10 to 14, and 15 to 19 years (compared with ages 5 to 9 years) were associated with increased risk of mortality, as was HIV infection, previous TB treatment, and extrapulmonary involvement. The SMR of 15 to 19-year-old female patients was more than double that of male patients the same age (55.3 vs 26.2). Among 10 to 14-year-olds and those who were HIV-positive, SMRs increased over time.

CONCLUSIONS:

Mortality in South African children and adolescents treated for TB is declining but remains considerable, with 2% dying during 2016. Adolescents (10 to 19 years) and those people living with HIV have the highest risk of mortality and the greatest SMRs. Interventions to reduce mortality during TB treatment, specifically targeting those at highest risk, are urgently needed.

Published: March 2021

El asma es una enfermedad del sistema respiratorio cuyos síntomas incluyen dificultad para respirar, opresión del pecho, tos y sibilancias. Distintos tratamientos han sido investigados y probados para su control, siendo el tratamiento con esteroides antiinflamatorios el más utilizado. No obstante, la biorretroalimentación se ha posicionado como un tratamiento con relevancia y efectividad clínica. Este estudio realizó una revisión sistemática que contó con 16 artículos sobre el uso de la biorretroalimentación como tratamiento para el asma. Los criterios de elegibilidad fueron: a) La variable dependiente debía ser asma y utilizar biorretroalimentación como tratamiento. b) Ser un estudio experimental o cuasi experimental y brindar el tamaño de la muestra. c) Tener grupo control, pre y postest. Los resultados sugieren que el uso de biorretroalimentación de respiración y variabilidad de la tasa cardiaca son efectivos cuando se trata de asma leve a moderada y, aún más, si se acompaña de medicación y otros tratamientos como relajación. Esto implica que podría ser considerada como tratamiento probablemente eficaz cuando el tratamiento farmacológico no sea viable.

A long-overlooked Mamluk bridge spanning the W?d? al-Hasi (Na?al Shiqma) between Gaza andMajdal (Ashqelon) was built at the behest of Sultan Baybars about 1270, as mentioned by ?Izz al-D?n Ibn Shadd?d in his Ta?r?khal-M?lik al-??hir. It was also noted in a variety of travel accountsspanning the 17th through 19th centuries and it was even photographed in the 1880s. Later itbecame a point of interest during the Great War when it was shelled by the British Navy as partof the Third Battle of Gaza, yet it survived to be repaired. Since it was on an important road evenin 1948, it was destroyed by a unit of Palmach in an attempt to impact infrastructure. The bridgeis one of the smallest of the six known Baybars bridges, yet it fully fits with the technologicalcharacteristics of the other examples.

Published: March 2021

ABSTRACT Objective: Although the mobile-bearing Oxford unicompartmental knee arthroplasty (OUKA) seems an appropriate procedure to treat spontaneous osteonecrosis of the knee (SONK), aseptic tibial component loosening was the leading cause for medial UKA failure. This study aimed to observe short-term and midterm clinical outcomes following OUKA and determine whether tibial lesion affects the procedure clinical and radiographic outcomes. Methods: Sixty patients (mean age 73.1 ± 6.6 years) diagnosed with SONK in the medial femoral condyle and treated with OUKA were separated into two groups using T1-weighted preoperative magnetic resonance imaging (MRI): group F (necrotic lesion confined to the femur) and group T (necrotic lesion spread to the tibia). The Oxford Knee Score (OKS), maximum flexion angle (MFA), and radiographic findings (radiolucent line and subsidence) were compared between the two groups using unpaired t-test. Results: Both groups showed significant improvement in OKS and MFA values at the final follow-up, but without significant differences in the clinical and radiographic outcomes. Conclusion: OUKA is a reliable treatment procedure for SONK in the short and midterm. The presence of tibial lesions on preoperative MRI does not affect postoperative radiographic and clinical outcomes. Level of Evidence IV, Case Series.

ABSTRACT Objective: To compare bone marrow aspirate concentrate (BMAC) with the standard treatment for gluteal tendinopathies. Methods: 48 patients diagnosed with gluteal tendinopathy at a university hospital were selected by a randomized clinical trial and divided into two groups: (G1) bone marrow aspirate concentrate and (G2) corticosteroid injections. Results: 40 of the 48 selected patients were monitored for six months and both groups showed better scores. Visual analog scale (VAS) scores and Lequesne index were statistically significant higher in patients submitted to BMAC treatment when compared to standard treatment. Both groups improved their quality of life, without statistically significant difference. Conclusion: BMAC constitutes an alternative to gluteal tendinopathy standard treatment, proving to be a safe technique with promising results when combined with multidisciplinary team behavioral therapy.

Abstract Brazil's current housing deficit exceeds 6 million homes and a demand of 10 million homes for low-income families is expected by 2040. On the other hand, during the last 10 years, approximately 850,000 social housing units have been delivered through the "My House, My Life" Program - (Programa Minha Casa, Minha Vida - PMCMV). Despite these numbers, several studies suggest some problems related to the low quality of the houses. This article aims to investigate the design parameter related to the geometry of social housing in Chapecó/SC, Brazil, which contributes to the achievement of the best thermal performance. Parametric methods and multi-objective optimizations were utilized, two objective-functions were optimized regarding the degree-hours for cooling and heating. The results showed significant improvements, reaching up to 98% during the hot period and 49% during the cold period. Guidelines were defined to assist architects in the early-phases of the social housing design based on the climate of the target region. However, the best design solutions for thermal comfort throughout the year can only be indicated with computational methods.

Abstract Recent studies underline that simple and non-invasive retrofit solutions can recover natural ventilation potential in existing buildings under temperate climate. Nonetheless, the efficiency of these solutions in dense urban contexts under hot and humid climate remains unclear. This paper aims to evaluate the thermal comfort gains caused by natural ventilation when retrofitting an office building in downtown Rio de Janeiro. Computational Fluid Dynamics (CFD) and thermal simulations are carried out on Ansys CFX and Design builder to assess indoor air flow before and after retrofit. The diagnosis of the current scenario indicates that the surrounding buildings block a significant part of the wind flow, and occupants experience only a few hours of thermal comfort during the year, especially on lower floors. To increase indoor air flow, the fixed upper windows were transformed into pivot windows and kept open permanently. This measure increases the annual hours of thermal comfort by 0.5-35%, depending on the floor and the adaptive comfort model. These findings suggest that natural ventilation itself may not be sufficient to ensure occupants' comfort throughout the year under the investigated context.

Abstrac The literature presents several BIM maturity models for projects, organizations and individuals. However, there is still a gap in models for Higher Education Institutions (HEIs). Consequently, there is an absence of studies that measure the BIM maturity of those institutions. Thus, the present study aims at (i) present a BIM maturity matrix model for HEIs; (ii) perform the measurement of BIM maturity in the HEIs in the state of Ceará, Brazil. The developed model is structured into three BIM fields (Policies, Processes and Technology), through 16 criteria and divided into five maturity levels. This research analyzed 26 courses in Civil Engineering as well as Architecture and Urbanism, in both public and private HEIs, therefore obtaining the Degree of Maturity, the Maturity Index, as well as the characteristics of BIM use. As a contribution, the study presents: (i) a theoretical contribution through the proposal of a BIM maturity model for HEIs, allowing other institutions to measure their performance; (ii) BIM characterization in HEIs, as well as the barriers for its adoption, uses and BIM disciplines; (iii) measurement of HEIs' maturity. The measurement of BIM maturity in the HEIs in Ceará state allowed an overview of them, becoming part of a macro-diagnostic state in the sector.

Abstract The poor initial resilience of the ground-breaking Brazilian urban social housing programme ‘Minha Casa, Minha Vida’(MCMV) affects millions of people, who have tried to adapt their homes, survived the unexpected and have to reinvent themselves constantly. This study delimits the elements that compose the concept of resilience, namely: the impacts, vulnerabilities and adaptive capacities that characterize the resilience of the built environment in the case study selected. To achieve these aims, advanced Post-Occupancy Evaluation (POE) and Co-production techniques have been applied in the case study of a typical Brazilian MCMV development in Uberlandia (Brazil). The results highlighted factors going beyond the typical vulnerabilities already seen in most of these developments. They pointed out the adaptive recovery capacities as key factors for resilience. This case study provides the means to investigate resilience and its variables in depth within the specific context of MCMV’s social housing, subsidising designers and public policies makers in the elaboration of more resilient projects for these social housing communities.

Resumo Estudos têm apontado o importante papel dos espaços públicos como suporte para uma vida mais saudável. O objetivo da pesquisa foi verificar a existência de associação entre as configurações espaciais de parques localizados em áreas socioeconômicas distintas com a prática de atividade física. A estratégia metodológica foi a de estudo de caso comparativo em dois parques na cidade de Londrina, PR, a partir do uso dos protocolos Soparc (System for Observing Play and Recreation in Communities) e Para (Physical Activity Resource Assessment) para capturar dados dos usuários, atividades e intensidade de atividade física e as características dos parques. Os resultados indicaram associação entre instalações como academia ao ar livre, pista de caminhada, campo esportivo, área de piquenique e arquibancada com a prática de atividade física em nível moderado/vigoroso. As análises apontaram diferenças qualitativas de inserção, acessos, entorno imediato e condições diferenciadas dos parques. Os resultados contribuem para subsidiar diretrizes espaciais para projetos de parques, bem como motivar um debate interdisciplinar no uso de protocolos validados e aplicados nas pesquisas da área da Saúde.

Published: March 2021

Resumo A confiabilidade está relacionada ao grau de confiança de um sistema, o qual deve ser estabelecido em projeto, prevendo-se e especificando-se suas condições de operação. O Anexo E da norma NBR 7190:1997 destinada a projetos de estruturas de madeira apresenta resultados de uma ampla amostragem de diferentes espécies de dicotiledôneas e coníferas, com grande variação no número de exemplares, fixando um coeficiente de variação (CV) para solicitações normais e tangenciais igual a 18% e 28%, respectivamente. Este trabalho avaliou, com enfoque probabilístico, a distribuição de frequência de resistência à compressão paralela às fibras das amostras apresentadas no modelo normativo, buscando especificar-se o índice de confiabilidade estabelecido. Os resultados apontam que os dados propostos podem não ser normalmente distribuídos, acarretando distorções na obtenção da resistência característica. A adoção de um único coeficiente de variação para coníferas e dicotiledôneas não foi ratificada na análise dos dados e, ao se considerar a homogeneização de classes, também são gerados diferentes coeficientes de variação. Sobre a proposta de revisão da NBR 7190, conclui-se que a inclusão de mais uma classe de resistência (D50) melhora a distribuição das amostras, contudo, a supressão do Anexo E dificulta a categorização das classes por espécies.

Published: March 2021

Resumo Com o aumento do processo de urbanização e da população das cidades, surge a necessidade de entender o custo energético para produção dos materiais de construção. Entre os instrumentos utilizados, o aporte de energia é um importante instrumento no monitoramento do uso de fontes de energia não renováveis para produção de concretos convencionais, o que demanda novas pesquisas na área. Neste trabalho, um modelo híbrido ANFIS (Adaptive Neuro-Fuzzy Inference System) foi desenvolvido para predição do aporte de energia, para a avaliação da demanda de energia necessária para cada um dos componentes na produção de concretos convencionais (cimento, água, agregado miúdo e agregado graúdo), mediante a utilização de 101 dosagens experimentais, 101 dosagens para validação e coeficientes energéticos disponíveis em literaturas. Identificou-se que a escolha adequada da dosagem pode gerar uma economia no custo energético para produção do concreto da ordem de 24,77%, mantendo a característica mecânica de resistência à compressão para construções convencionais.

Resumo O contrapiso é uma camada do sistema de piso cuja função é regularizar, dar caimento e absorver deformações. Comumente, é executado com uma argamassa seca à base de cimento que apresenta uma baixa produtividade. O emprego de um material autonivelante à base de gesso permite um endurecimento mais rápido, menor custo e lisura da superfície com obtenção de menores espessuras. O objetivo desta pesquisa foi desenvolver pastas de gesso autonivelantes (GSL), apenas com gesso beta como aglomerante e avaliar a influência do aditivo superplastificante à base de policarboxilato (PCE). As relações água/gesso (a/g) de 0,35; 0,40; 0,45; 0,475; 0,50 e 0,55 foram empregadas e o teor de PCE foi ajustado para a fluidez adequada. As pastas foram caracterizadas no estado fresco quanto aos tempos de pega, espraiamento e calor de hidratação. No estado endurecido quanto a resistência à compressão, à tração na flexão, dureza superficial e MEV. As pastas de GSL foram obtidas com relação a/g de 0,45 e 0,475, contendo 3,5% e 2,0% de PCE, respectivamente. O PCE aumentou os tempos de pega, modificou a estrutura cristalina do hemi-hidrato e reduziu o intertravamento dos cristais com a consequente diminuição das propriedades mecânicas.

Published: March 2021

Resumo A demanda mundial de energia está em constante crescimento, ao mesmo tempo as reservas de combustíveis fósseis estão diminuindo e não serão suficientes para satisfazer as demandas globais de energia no futuro. Além disso, os sistemas convencionais de aquecimento e refrigeração consomem a maior parte da demanda por energia elevando consideravelmente os custos. O trocador de calor solo-ar (TCSA) é uma opção sustentável que consume menos energia com potencial para melhorar as condições térmicas em edifícios. Apesar de ser uma tecnologia simples e antiga, no Brasil as pesquisas sobre eles são muito limitadas. Nesse contexto, faltam estudos na Região Norte deste país, em particular na cidade de Belém do Pará. Portanto, o objetivo desta pesquisa é desenvolver um modelo numérico tridimensional do TCSA usando ANSYS Fluent para avaliar a influência de parâmetros operacionais e construtivos, tais como a velocidade de escoamento do ar, comprimento e diâmetro do duto no desempenho térmico desse sistema adaptado às condições climáticas e às características do solo dessa cidade. A partir dos resultados obtidos, conclui-se que esse sistema pode reduzir a temperatura do ar na saída do duto até em 5,91 °C.
