У статті розкрито принципи реалізації технології замкнутого циклу використання води на території приватної власності (приватного будинку). Структуровано стандарти сертифікації зеленого будівництва та визначено показники відповідності будівельних проектів. Підкреслено, що метою впровадження технологій зеленого будівництва, на території приватного будинку є, перш за все, зниження рівня споживання енергетичних та матеріальних ресурсів при одночасному збереженні або підвищенні якості приватного будинку та комфорту його внутрішнього середовища. Визначено поняття «зеленого» будівництва та розкрито підхід до провадження інноваційної технологій в умовах сучасного будівництва. Наголошено, що «зелені» технології, які можуть бути реалізовані у поєднанні з існуючою інфраструктурою або як автономні системи, можуть підтримувати перехід до нової парадигми повторного використання води шляхом інтеграції циркулярної економіки у принципи водного господарства країни, міста, поселення, району, тощо. Представлено схематичне зображення існуючої системи використання водних ресурсів, яка заснована на зборі дощової води, її очищені та використанні. Наведену паралельну систему збору дощової води зручно застосовувати на об'єктах індивідуального заміського житлового будівництва, на територіях, віддалених від промислових зон. Підкреслено, що серед переваг використання дощової води у побуті слід відзначити суттєве скорочення споживання звичайної водопровідної води, оскільки її витрати залежать лише від кількості мешканців та їх звичок. Сформовано схему реалізації технології замкнутого циклу використання води на території приватної власності (приватного будинку). Наголошено, що для реалізації замкнутого циклу необхідним є встановлення спеціального обладнання, яке включає багатоступінчасті фільтри, різні реагенти та коагулянти, що доводять хімічний склад води до санітарних норм. Зазначено, що основною проблемою «зелених технологій» та розвитку екодевелопменту в цілому залишається дорожнеча їх реалізації, оскільки обладнання, що використовується, є імпортним, і не кожен забудовник чи замовник зможе дозволити собі реалізацію даної технології на своєму власному об'єкті.
Insights on amyloid-related imaging abnormalities from the “Pre-Alzheimer’s disease Alliance of China”
Authors: Li Tao-Ran , Han Ying , Pre-AD Alliance of China on behalf of the
Published: March 2022

Alzheimer’s disease (AD) is the most common cause of dementia and accounts for 60 – 80% of all such cases. For approximately 20 years, the research and development of new drugs for AD all ended in failure; however, aducanumab was recently granted accelerated approval by the US Food and Drug Administration. Aducanumab is a representative passive anti-β-amyloid (Aβ) immunotherapy and is the only approved drug that directly targets the pathological changes of AD; it can significantly reduce brain Aβ deposition, which is a hallmark of AD. During the clinical trials of amyloid-targeting monoclonal antibodies, represented by aducanumab, amyloid-related imaging abnormalities (ARIA) were the most common and important adverse reactions. Therefore, before the large-scale clinical application of amyloid-targeting monoclonal antibodies, clinicians and radiologists need to fully understand ARIA so that they can make more informed decisions. Considering the very uneven distribution of medical resources in China, we — on behalf of the “Pre-AD Alliance of China” — believe that it is necessary to write a consensus to elaborate on the mechanisms, risk factors, identification methods, and administration processes of ARIA.

Published: March 2022

Objective. There is increased concern regarding acute ischemic stroke (AIS) in patients with coronavirus disease 2019 (COVID-19). The aim of this study was to depict the manifestations and outcomes of COVID-19-associated AIS.
Methods. We systematically searched for eligible studies describing AIS in patients with COVID-19 using PubMed, Embase, and Web of Science up to November 29, 2021. We complied with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and used the Newcastle–Ottawa Scale to assess data quality. The data were pooled using fixed- and random-effects models.
Results. Thirty-eight eligible studies involving 76,894 participants were included in this meta-analysis. Compared with AIS patients who did not have COVID-19, patients with COVID-19 were more likely to have anterior circulation stroke (odds ratio [OR]: 2.29, 95% confidence interval [CI]: 1.03 – 5.10; I2: 37%), particularly involving the internal carotid artery (OR: 1.85, 95% CI: 1.19 – 2.88; I2: 0); more severe neurological deficit (National Institutes of Health Stroke Scale [NIHSS]) (weighted mean difference [WMD]: 3.21, 95% CI: 2.13 – 4.29; I2: 64%); higher proportion of cryptogenic stroke (OR: 1.83, 95% CI: 1.24 – 2.70; I2: 62%), large vessel occlusion (OR: 1.68, 95% CI: 1.10 – 2.57; I2: 75%), and multi-territory involvement (OR: 2.64, 95% CI: 1.62 – 4.29; I2: 0%); higher C-reactive protein levels (WMD: 55.90, 95% CI: 33.32 – 78.49; I2: 67%), and D-dimer levels (standardized mean difference: 0.81, 95% CI: 0.52 – 1.10; I2: 59%). The proportion of poor outcomes were higher among patients with COVID-19, including increased risk of in-hospital death (OR: 3.70, 95% CI: 2.73 – 5.02; I2: 64%) and lower possibility of favorable discharge (OR: 0.49, 95% CI: 0.39 – 0.61; I2: 0). However, COVID-19 did not increase the risk of hemorrhagic transformation (OR: 1.34, 95% CI: 0.91 – 1.98; I2: 39%) and symptomatic intracerebral hemorrhage (OR: 1.46, 95% CI: 0.81 – 2.62; I2: 0).
Conclusion. AIS patients with COVID-19 seem to display a pattern of large vessel occlusion and multi-territory infarcts. These patients have high inflammatory marker levels and increased D-dimer levels, which implies that thrombosis and/or thromboembolism might be the underlying mechanism. These patients tend to have worse prognosis regardless of whether they receive reperfusion treatment.

Devoted to the Truth
Authors: Walter Hugo G.
Published: March 2022

This book is a collection of great essays which discuss four brilliant and impressive investigators and detectives in literary masterpieces by Arthur Conan Doyle, Agatha Christie, and Dorothy Bowers. The focus of this book is on Sherlock Holmes, Hercule Poirot, Jane Marple, and Dan Pardoe. These highly intelligent, perceptive, problem-solving, resilient, and resourceful investigators are committed to examining the evidence in any situation carefully, fairly, and honestly and devoted to searching for and discovering the truth in various criminal cases, even though such heroic endeavors frequently threaten their own lives. In Chapter Seven of Agatha Christie�s The Murder of Roger Ackroyd Hercule Poirot agrees to accept the case which is presented to him only if he may "go through with it to the end" and search for "all the truth." In numerous investigations Sherlock Holmes, Hercule Poirot, Jane Marple, and Dan Pardoe demonstrate not only an extraordinary commitment to searching meticulously and valiantly for the whole truth but also the absolute genius to discover it.

Published: March 2022

Aim: Whether incident left bundle branch block (LBBB) is associated with increased cardiovascular (CV) morbidity and mortality in treated hypertensive patients with left ventricular hypertrophy (LVH) is unknown. Thus, the present study aimed to examine CV outcomes of incident LBBB in treated hypertensive patients with LVH.
Methods: In the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study, 9,193 hypertensive patients with LVH on screening electrocardiogram (ECG) were randomized to losartan or atenolol based treatment. Participants (n = 8,567) did not have LBBB (Minnesota code 7.1) on baseline ECG. Cox regression models controlling for significant covariates assessed independent associations of incident LBBB with CV events and all-cause mortality during 4.8 years mean follow-up.
Results: Annual follow-up ECGs identified 295 patients (3.4%) with incident LBBB associated with male gender (P < 0.05), older age, higher Cornell voltage (both P < 0.005) and history of diabetes, isolated systolic hypertension and prevalent CV disease. When adjusted for the history of previous CV disease, diabetes, isolated systolic hypertension, the Framingham risk score, ECG-LVH and randomized study treatment, Cox regression models showed that incident LBBB predicted higher risk of the composite endpoint CV death, myocardial infarction and stroke [hazard ratio (HR) 1.9, 95% confidence intervals (CIs) 1.3–2.9, P < 0.001], CV death (HR 3.0, 95% CIs 1.84–5.0, P < 0.001), heart failure (HR 3.6, 95% CIs 1.9–6.6, P < 0.001) and all-cause mortality (HR 3.0, 95% CIs 2.0–4.3, P < 0.001).
Conclusions: These data suggest that among hypertensive patients with ECG-LVH receiving aggressive antihypertensive therapy, incident LBBB independently predicts increased risk of subsequent CV events including congestive heart failure and CV and all-cause mortality (ClinicalTrials.gov identifier: NCT00338260).

Edadismo: la barrera invisible
Authors: Seco Lozano Luisa
Published: March 2022

La enfermedad renal crónica es frecuente en las personas mayores y su prevalencia se incrementa conforme aumenta la edad. El envejecimiento de la población en diálisis tiene unas características que no se pueden extrapolar a la población en general. Esta patología además es un reto para la salud pública con importantes implicaciones sociales y económicas. Las enfermeras nefrológicas solemos ser los primeros profesionales en detectar numerosas problemáticas sociales, relacionales, incluso económicas que presentan las personas en diálisis. El edadismo es uno de los retos emergentes  al que las enfermeras nefrológicas vamos a tener que enfrentarnos en nuestra práctica diaria. Para ello necesitaremos formarnos, sensibilizarnos, educarnos y educar a los demás, tareas que no nos son ajenas y para las que necesitaremos usar los recursos de divulgación de que disponemos para acompañar a la sociedad en el proceso de visibilización, denuncia y transformación de una discriminación que nos afecta a todos. Utilizar esta editorial para hablar del edadismo es un ejemplo de cómo las enfermeras nefrológicas se hacen eco de la necesidad de cuidar no sólo de los aspectos técnicos, sino de liderar los cambios necesarios para vivir y cuidar en una sociedad justa y solidaria.

Published: March 2022

Introducción: La lesión renal aguda se ha convertido en una complicación común en los niños hospitalizados, especialmente cuando están en una situación clínica crítica. Objetivo: Conocer y sintetizar la bibliografía científica más actualizada sobre la lesión renal aguda en la población pediátrica. Metodología: Estudio descriptivo de revisión integrativa. La búsqueda de artículos se ha realizado en las bases de datos Pubmed, Scopus y Google Scholar. La estrategia de búsqueda se estableció con los siguientes términos MeSH: ”acute kidney injury”, “children” y “pediatric”. La calidad metodológica se realizó mediante la escala STROBE. Resultados: Se incluyeron 35 artículos, 19 de diseño observacional retrospectivo, 12 observacionales prospectivos, 3 revisiones bibliográficas y 1 estudio cualitativo. No hay variables sociodemográficas destacables que impliquen mayor probabilidad de presentar lesión renal aguda. Tanto la etiología como los factores de riesgo son muy variables. La lesión renal aguda se asocia a mayor número de complicaciones y estancia hospitalaria. No hay evidencia de cuidados enfermeros en la lesión renal aguda en pacientes pediátricos. Conclusiones: Se observa una falta de homogeneidad en los criterios de definición, incidencia, etiología, factores de riesgo y de tratamiento en los pacientes pediátricos con lesión renal aguda, y escasez de artículos originales de investigación. La lesión renal aguda pediátrica se asocia a mayor mortalidad, morbilidad, mayor estancia hospitalaria y mayor duración de la ventilación mecánica. El papel de enfermería en el manejo del tratamiento conservador y de las terapias de reemplazo renal de este cuadro, es fundamental en la supervivencia de estos pacientes.

Evaluating Nicotine as a Cognitive Enhancer
Authors: Editorial Office
Published: March 2022

Nicotine is a bicyclic chemical compound that is derived from tobacco plants. Due to its effect on the brain, nicotine is addictive and has long been used as a popular recreational drug. In numerous studies, nicotine has been shown to improve memory and reaction time performances. Some nicotine skin patch studies have exhibited characteristics of a possible treatment for cognitive impairments (Rezvani and Levin, 2001). Although many studies have shown that nicotine has cognitive-enhancing effects, there is not sufficient research conducted to examine the specific impacts of nicotine on reaction time. The aim of this study is to assess how reaction time differs before and after nicotine use for people who regularly use the drug and to test how the reaction times of non-users compares to those of regular users. This study was conducted on individuals aged 18 to 22. A Brain Gauge device and its associated software was used to collect reaction time data. Each user completed the Hardware Reaction Time test, which required the participant to press a button with their right index finger as soon as they felt the stimulus that was delivered to their right ring finger. It was found that people who did not use nicotine had faster reaction times than those who use nicotine regularly. However, regular nicotine users had slower reaction times before nicotine use as compared to after nicotine use. Although these results improve our understanding of the effects of nicotine use, there were limitations to the study. The experiment was not well-controlled as the environment of each participant was different, and the population tested consisted of mostly people in their early 20s. Further studies should be conducted with more controlled testing conditions and with a more diverse population.

Authors: Reski Nur Awalia
Published: March 2022

This study aimed to determine the measurement of performance in the Village Government of Jabal Nur, Kec. Kodeoha, North Kolaka Regency in 2015-2019 using the concept of Value For Money. Performance measurement is one of the factors for a private or public organization. Performance measurement is used as a control tool in an organization to evaluate the results of activity and determine the success of the management carried out by an organization. The application of the value for money concept is important for the government as a public service because the implementation of this concept will provide benefits for assessing: 1) the effectiveness of public services, 2) the quality of public services, 3) spending allocations that are more oriented to the public interest, and 4) increasing public cost awareness as the root of the implementation of public accountability. The results of this study indicate that the performance of the Jabal Nur village government has been said to be economical because the percentage ratio has never exceeded 100%; in terms of efficiency, government performance is efficient even though the first 3 years are in balanced efficiency, but in years 4 and 5 the level of efficiency has increased, and from in terms of the effectiveness of the performance of the village government of Jabal Nur has been effective even though in 2017 the level of effectiveness was according to. Still, the following year the level of effectiveness increased again.
Minkowski Functionals of SDSS-III BOSS: Hints of Possible Anisotropy in the Density Field?

Published: March 2022

We present measurements of the Minkowski functionals extracted from the SDSS-III BOSS catalogs. After defining the Minkowski functionals, we describe how an unbiased reconstruction of these statistics can be obtained from a field with masked regions and survey boundaries, validating our methodology with Gaussian random fields and mock galaxy snapshot data. From the BOSS galaxy data, we generate a set of four density fields in three dimensions corresponding to the northern and southern skies of LOWZ and CMASS catalogs, smoothing over large scales (Gaussian smoothing scale of 35 Mpc) such that the field is perturbatively non-Gaussian. We extract the Minkowski functionals from each data set separately, and measure their shapes and amplitudes by fitting a Hermite polynomial expansion. For the shape parameter of the Minkowski functional curves a
0, that is related to the bispectrum of the field, we find that the LOWZ-South data presents a systematically lower value of a
0 = −0.080 ± 0.040 than its northern sky counterpart a
0 = 0.032 ± 0.024. Although the significance of this discrepancy is not very high, it potentially indicates some systematics in the data or that the matter density field exhibits anisotropy at low redshift. By assuming a standard isotropic flat ΛCDM cosmology, the amplitudes of the Minkowski functionals from the combination of northern and southern sky data give the constraints Ωc

Probing the Inner Edge of Dead Zones in Protoplanetary Disks with ALMA and Next Generation Very Large Array
Authors: Ueda Takahiro , Ricci Luca , Flock Mario , Castro Zachary
Published: March 2022

The discovery of substructures in protoplanetary disks by the Atacama Large Millimeter/submillimeter Array (ALMA) has provided us with key insights into the formation of planets. However, observational constraints on the formation of rocky planets have been still sparse, especially because of the limited spatial resolution. The inner edge of the so-called dead zone is one of the preferential sites of rocky planet formation. We investigate the capabilities of ALMA and Next Generation Very Large Array (ngVLA) for observing a dust concentration expected at the inner edge of the dead zone around a Herbig star. Herbig Ae/Be stars are useful laboratories for exploring the evolution of rocky grains in protoplanetary disks because of their high luminosity that pushes the dead zone inner edge outward. We find that, thanks to its unprecedented angular resolution and sensitivity, ngVLA can detect the dust concentration at the dead zone inner edge, with a reasonable integration time of 10 hr at λ = 3, 7 mm, and 1 cm. The dust concentration is expected to be optically thick at the ALMA wavelengths and cannot be spatially resolved due to its limited resolution. On the other hand, the flux density from the inner disk regions (∼3–4 au) observed with current VLA is higher for disks with a dust ring, and hence would be a useful indicator that helps us choose potential candidates of disks having a dust concentration at the innermost region. With these observations we can characterize the process of dust concentration in the innermost disk regions, where rocky planets can form.

The CNIa0.02 project aims to collect a complete, nearby sample of Type Ia supernovae (SNe Ia) light curves, and the SNe are volume-limited with host-galaxy redshifts z
host < 0.02. The main scientific goal is to infer the distributions of key properties (e.g., the luminosity function) of local SNe Ia in a complete and unbiased fashion in order to study SN explosion physics. We spectroscopically classify any SN candidate detected by the All-Sky Automated Survey for Supernovae (ASAS-SN) that reaches a peak brightness <16.5 mag. Since ASAS-SN scans the full sky and does not target specific galaxies, our target selection is effectively unbiased by host-galaxy properties. We perform multiband photometric observations starting from the time of discovery. In the first data release (DR1), we present the optical light curves obtained for 247 SNe from our project (including 148 SNe in the complete sample), and we derive parameters such as the peak fluxes, Δm

On the Detectability of Post-common-envelope Binary Central Stars of Planetary Nebulae
Authors: Hume George , Yarker Paige , Jones David
Published: March 2022

Common envelope evolution is widely accepted as the principal shaping agent in the formation of aspherical planetary nebulae. However, only some 20% of planetary nebulae are found to host post-common-envelope binary central stars. To probe the detectability of post-common-envelope binary central stars, and their potential to evade detection, we simulate the light curves of an array of these systems varying their stellar and orbital parameters. We find that while binaries with late-type companions and/or long orbital periods will likely go undetected, they are unlikely to represent a large fraction of the overall post-common-envelope central star population.
Inactivité de la raison et influence du sentiment : de la métaéthique humienne au point de vue architectonique
Authors: Jaffro Laurent
Published: March 2022

Selon Hume, la raison, à elle seule, est impuissante non seulement à apprécier d’une manière ou d’une autre une attitude ou une situation, à déterminer une action, mais aussi à susciter une croyance. Cette thèse fait système avec une thèse de l’influence du sentiment. Cet article s’interroge sur les manières dont on peut ou non considérer la thèse de l’impuissance de la raison en matière pratique comme une forme particulière d’une thèse très générale de l’inactivité de la raison. En outre, on s’efforce de montrer que la thèse selon laquelle l’influence provient de sentiments particuliers doit être comprise de plusieurs manières, selon que tel ou tel domaine est concerné, mais également selon qu’il s’agit d’une thèse formelle ou d’une thèse matérielle. Au-delà des usages de la position humienne dans la métaéthique contemporaine, il s’agit d’apprécier la portée architectonique des conceptions que Hume proposait des rôles de la raison et du sentiment dans la détermination de la croyance et de la volonté.
La « division des sexes » chez Durkheim : éléments pour une sociologie comparative
Authors: Théry Irène
Published: March 2022

Contrairement à Auguste Compte qui voyait dans la famille organisé autour d’un couple hétérosexuel procréateur non seulement la véritable base de la société, mais aussi, par déduction, la justification des différences naturelles des sexes jusqu’à la subordination de la femme à l’homme, Durkheim s’emploie à démontrer que les différences observables entre les deux sexes ne sont en aucun cas naturelles, mais bien le produit de la division sexuée du travail, ce qui revient à rompre radicalement avec les représentations dominantes à son époque. Par ailleurs, la famille conjugale n’est pas, selon lui, la modèle vers lequel tendrait notre nature, mais bien une institution sociale, autrement dit une construction, dont la cohérence normative résulte avant tout de la division du travail. Marcel Mauss poursuivra le travail de distanciation de son oncle en franchissant une autre étape. Les progrès fulgurants de l’ethnographie au début du XXe siècle permirent en effet à ce dernier de démontrer que plus on s’éloigne du modèle des sociétés modernes, plus la division par sexes est forte. Loin d’être le produit d’une conception naturelle des différences, les rapports entre les sexes dans les sociétés polysegmentaires relèvent en réalité de la règle et par conséquent d’une division "par sexes". Ce n’est pas à la perfection de la nature humaine et à la civilisation que l’on doit la distinction des qualités masculines et féminines puisque la division par sexes était déjà réglementée dans les sociétés dites "primitives".
Faire sens d'un déplacement
Authors: Demonteil Marion
Published: March 2022

Cet article prend pour objet les haut·es fonctionnaires en fin de carrière. Il contribue à penser les dernières étapes de leur trajectoire professionnelle en déplaçant la focale depuis les conditions de promotion et de mobilité vers les modalités d’ajustement, désajustement et maintien dans les positions de fin de carrière. À partir du cas des inspectrices et inspecteurs du ministère de la Culture, anciens cadres administratifs, conservateurs et conservatrices du patrimoine mais également danseurs et danseuses, administrateurs et administratrices de théâtre ou encore architectes, l’étude met à profit l’analyse dispositionnelle des pratiques professionnelles, la sociologie de la vocation et celle du vieillissement professionnel, pour traiter de l’articulation entre l’action publique et les caractéristiques sociales des agents de l’État. La diversité des formes d’ajustement comme les résistances à l’institution, qui vont parfois jusqu’à la sortie de rôle, apportent un éclairage original sur ces déplacements professionnels tardifs.
Use of intravascular hypo- and hyper-attenuation on non-contrast-enhanced computed tomography in diagnosing acute septic thrombophlebitis
Authors: Yoshikawa Satoshi , Ueda Takeshi , Fujiwara Takuya
Published: March 2022

Septic thrombi, such as those observed in pylephlebitis and Lemierre's syndrome, are characterized by portal vein thrombosis and venous thrombosis with bacterial infection. Although radiographic findings of septic thrombus on contrast-enhanced computed tomography have been well described, no report has described the characteristics of non-contrast-enhanced computed tomography. We describe a case series of septic thrombophlebitis exhibiting intravascular hypo- and hyper-attenuation on non-contrast-enhanced computed tomography. These radiographic features reflect the pathophysiology of septic thrombus, and therefore, it is important and useful to evaluate thrombus attenuation on non-contrast-enhanced computed tomography.
The effects of electrical and ultrasonic pretreatments on the moisture, oil content, color, texture, sensory properties and energy consumption of microwave-fried zucchini slices
Authors: Rayman Ergün A.
Published: March 2022

In this study, the effects of a moderate electrical field application and two different blanching methods (conventional and ultrasound) on the frying (deep-frying in oil at 180 °C for 6 minutes and compared to the microwave (400W)) of zucchini slices were investigated. Microwave-fried samples presented a lower moisture content than deep fried ones. The moderate electrical field significantly reduced the oil content before the microwave frying. Greenness (–a*), which is important for the zucchini samples, was found at its best (-3.25) in the combination group of moderate electrical field pre-treated, ultrasound blanched, and microwave fried. Gumminess, cohesiveness, and fracturability of the zucchini slices decreased while chewiness, springiness, and resilience increased after microwave frying. The scores of the sensory test were higher for the ultrasonic blanching and microwave fried sample groups. Besides, these electrical methods were found more advantageous in terms of energy consumption.

Published: March 2022

A busca por novos materiais poliméricos, nas quais apresentem entre suas propriedades a capacidade de se apresentar como um material adsorvedor tem se tornado nos últimos anos, uma alternativa para remoção destes poluentes. A primeira parte deste trabalho apresentar os dados obtidos para a incorporação de nanopartículas de zeólita em fibras de PVDF, obtidos por meio de uma variação da técnica de fiação por sopro em solução (FSS) denominada Aerógrafo. Através das análises de DRX e as análises de fluorescência de raios X verifica-se, mesmo que timidamente a presença das partículas e dos de picos característicos de matriz polimérica e juntamente com as análises térmicas, a técnica de DSC e de TGA demonstram que a incorporação de zeólita do tipo clinoptilolita, bem como a formação de microfibras como observado nas micrografias em MEV, e ainda as mesmas não alteram a conformação e configuração do polímero e a sua presença, diminui a temperatura de degradação da matriz polimérica, como previsto na literatura.
EFEITO DA ADIÇÃO DE MICRO E MACROFIBRAS DE POLIPROPILENO (PP) ÀS FIBRAS DE AÇO SOBRE O COMPORTAMENTO MECÂNICO DO CONCRETO
Authors: Ferrari Vladimir José , Gobbi Drun Anderson
Published: March 2022

Nessa pesquisa foram analisadas as propriedades no estado fresco e endurecido de um CRF híbrido por meio da associação de microfibras e macrofibras de polipropileno (PP) com fibras de aço. O objetivo foi desenvolver um CRF com boa capacidade de absorção de energia na fase pós-pico do carregamento. Foram analisados cinco grupos de CRF com diferentes teores de fibras. O abatimento do tronco de cone foi utilizado para avaliar as condições de trabalhabilidade das misturas. Foram realizados ensaios em corpos de prova cilíndricos para obtenção da resistência à compressão, módulo de elasticidade estático e dinâmico. Essa última propriedade obtida pelo ensaio de excitação por impulso. Ensaios de flexão em corpos de prova prismáticos foram realizados utilizando-se um equipamento Instron/Emic visando-se a obtenção das resistências e tenacidade. Os resultados revelaram diminuição significativa nos valores da resistência à compressão e módulo. Os CRFs desenvolvidos apresentaram boa capacidade de carga após a fissuração, as fibras de aço agiram mais eficazmente em baixos níveis de deformação e as fibras de PP tiveram melhor desempenho em maiores níveis de deformação. O comportamento das diferentes fibras em distintos estágios de carregamento, permitiram obter um material com elevada capacidade de absorção de energia quando comparado aquele CRF contendo apenas fibras de aço.

JABUTICABA FRUIT BEER: PHYSICOCHEMICAL AND SENSORY EVALUATION
Authors: Imaizumi Vitor Massami
Published: March 2022

This research focused on craft beer production of jabuticaba (Myrciaria cauliflora Berg) “fruit beer” and the physicochemical and sensory analisys of the samples. The research was divided into four treatments regarding the stage of fruit addition during the brewing process (Boiling, Fermentation, Maturation) and the Control (all malt), with three replicates each. The mashing was performed by the infusion method, and the wort was boiled for 60 minutes. The fermentation took place at 10 °C ± 1, and the green beer was later bottled with priming sugar and bottle conditioned for carbonation. The maturation occurred in the bottles for 30 days at 0 °C ± 1, except for the Maturation treatment. The beers were analyzed physicochemically for the parameters of alcoholic content, real extract, apparent extract, apparent fermentability, true fermentability, color, bitterness, turbidity, pH, total acidity and carbon dioxide. The beers were submitted to sensory analysis by affective test using 9-point hedonic scale. The addition of jabuticaba increases the total acidity, CO2 content and bitterness of the beer, but does not alter its real extract, apparent extract and pH. Sensorially, treatments and Control had the same preference for all parameters analyzed (appearance, aroma, flavor and overall evaluation).
