Logo, o estudo se volta para a maneira como a narrativa denuncia e historiciza seus códigos de composição, adotando o humor como veículo de desconcerto que confessa a artificialidade da narrativa.
Analysis of exogenous auxin and cytokinin action in overcoming root restriction in green and variegated Benjamin fig
Authors: Benedetto Adalberto Di , Galmarini Claudio , Tognetti Jorge
Published: May 2023

Abstract Green and variegated Benjamin fig (Ficus benjamina) often suffer from root restriction when grown in pots. While exogenous cytokinin applications have proven effective in reversing this stress, the possibility that exogenous auxins, either alone or in combination with cytokinin, may also be helpful has received little attention. In this work, we analyse the response of green and variegated Ficus benjamina rooted cuttings growing in small pots to exogenous supply of auxin and cytokinin at different concentrations, either in single or combined applications. Our results show that both benzyl aminopurine (BAP) and indole acetic acid (IAA), at the highest concentration tested (100 mg L-1) increased leaf development and plant biomass accumulation in green and variegated Ficus genotypes. However, exogenous IAA and BAP appeared to elicit differential plant morpho-physiological responses. While BAP tended to enhance leaf appearance more than IAA did, the latter promoted leaf expansion in a steadier manner than BAP, thus resulting in plants with less, but larger, leaves than those treated with cytokinin. Despite these differences in plant architecture, regression analysis suggests that hormonal-induced growth promotion was solely attributable to enhanced carbon assimilation. Rather unexpectedly, IAA promoted net assimilation and photosynthesis rates at least as effectively as cytokinin. Possible mechanisms involved in growth and development promotion by exogenous application of both hormones are discussed. Auxin treatment may help overcome root restriction in Ficus as effectively as cytokinin in terms of growth promotion, although differences in plant architecture may arise as compared with plants sprayed with the latter hormone.

RESUMO Este artigo traz reflexões acerca de como a sociedade capitalista e patriarcal afeta a relação das mulheres com seu tempo e com seu lazer. Com o objetivo de mapear atravessamentos na relação entre mulheres, lazer e família, a partir de uma pesquisa com movimentos sociais brasileiros de mulheres, realizei um estudo bibliográfico, análise documental e entrevistas com lideranças de movimentos feministas brasileiros. Os resultados apontaram para aspectos macro e micropolíticos que colocam o lazer das mulheres em segundo plano nas reivindicações de tais movimentos. O vínculo estreio com o modelo de família apareceu como uma das motivações que afeta o lazer como direito pessoal. Trago para a reflexão alguns dos aspectos identificados.
Investigation of aggregate interlock contribution to shear strength of reinforced concrete and steel fiber reinforced concrete beams
Authors: Debella Leticia Col , Montoya-Coronado Luis Alberto , Resende Thomás Lima de , Pieralisi Ricardo
Published: May 2023

Abstract Shear strength in reinforced concrete (RC) beams, especially in steel fiber reinforced concrete (SFRC) beams is a subject of great interest in structural engineering. In the case of beams without transverse reinforcement, the failure is explained based on a predefined crack pattern and kinematics, and the transfer of shear force accomplished through different mechanisms. Among these mechanisms, the aggregate interlock is present in most of the existing shear strength mechanical models in the literature, with divergences regarding its performance and preponderance. Thus, this paper focuses on evaluating the contribution of aggregate interlock throughout the critical crack formation process up to the ultimate load by performing bending tests on small-scale rectangular RC and SFRC beams without considering the effect of transverse reinforcement. The Digital Image Correlation (DIC) technique is used to track the patterns of shear cracks and their associated kinematics by measuring the relative displacements of opening (w) and sliding (δ). A detailed description of the shear behavior of these beams is provided by quantifying the aggregate interlock using the simplified Walraven model. The results help to understand the level of contribution of the aggregate interlock, and the main differences between structural elements of concrete with and without steel fibers in the scope of the shear strength.

Published: May 2023

Abstract The use of construction waste as aggregate in the production of concrete is becoming a more frequent alternative due to the advantages associated with the sustainability aspect. Results obtained in experimental tests with recycled aggregate concrete suggest that mechanical properties such as elastic modulus, compressive, tensile and flexural strength tend to reduce with partial or total replacement of natural aggregate by recycled one. On the other hand, the use of steel fiber reinforcement can minimize the reduction of these properties, since the fibers tend to improve the material strength and ductility. This work proposes a numerical approach, seeking to better predict and understand the structural mechanical behaviors and failure patterns of reinforced recycled aggregate concrete slabs with and without steel fiber. Based on the finite element method, an appropriated constitutive damage model is employed to represent the nonlinear behavior of the conventional/recycled concrete, while an elastic-perfectly plastic model is used to describe the mechanical behavior of the reinforcements. To couple the independent FE meshes and incorporate the mutual interaction between the different components, rigid and non-rigid coupling technique is used to represent the perfect adherence or the bond-slip behavior. Seven concrete slabs were numerically analyzed either with different percentages of recycled aggregate replacement (0, 50 and 100%) or steel fibers content (0.0, 0.5 and 1.0%) and the results were compared with the experimental ones. The results showed that the applied methodology is capable of simulating with good accuracy the punching shear failure mechanism of the slabs. It was observed that the punching ultimate load decreased with increase of recycled aggregate content, as well as that the steel fiber addition can minimize the negative effects of recycled aggregate employment.

Web slenderness effects on flexure of compound normal and high-strength steel beams
Authors: Ellobody Ehab
Published: May 2023

This paper discusses web slenderness effects on the flexural behaviour of epoxy adhesive-bonded compound normal and high-strength steel beams. The compound beams were simply supported and consisted of an I-section connected, on its top flange, to a channel section using an epoxy adhesive. A non-linear three-dimensional finite-element modelling study was performed using Abaqus software for the analysis of the beams. The non-linear finite-element modelling was verified against tests on compound steel beams with different cross-sections. An extensive parametric study was carried out using the finite-element modelling to study the effects of the change in web slenderness, cross-sectional geometries, beam lengths and steel strengths on the flexural behaviour of compound steel beams. The failure moments predicted by the finite-element modelling were compared with the design moments predicted by the European code for steel beams in flexure. It is shown that the code generally overestimated the design failure moments for most of the epoxy adhesive-bonded compound steel beams investigated in this study. In addition, reliability analysis was performed to assess the reliability of the design rules of the code. Generally, it was found that the European code is unconservative and statistically unreliable for the epoxy adhesive-bonded compound beams investigated in this study.
Coalescence characteristics of vibrated drops on a wettability gradient surface
Authors: Chen Feng , Jia Zhihai , Deng Yong
Published: May 2023

The coalescence characteristics of two vibrated droplets at a certain distance on a microstructured surface with gradient wettability are investigated using a high-speed camera in this work. The results show that the volume ratio of the two droplets has a significant effect on the vibration modes. With the change in the volume ratio, the droplet exhibits different vibration modes, such as the pumping mode (PM), the rocking mode (RM) or the pumping–rocking mixed mode (PRM). In addition, the coalescence time of the two droplets varies with the volume ratio. When the volume ratio is close to 1, the two vibrated droplets are in synchronous PM and the coalescence time is the shortest. When the volume ratio is far from 1, the two droplets may show the RM, the asynchronous PM or the PRM. At this point, the coalescence time is increased, particularly for small volume ratios. Finally, the movement characteristics of three-phase contact lines are discussed, and a theoretical model is proposed to analyze the coalescence process. This work provides a new method to remove droplets rapidly, which is essential to enhance the heat-transfer performance of dropwise condensation.

Published: May 2023

The use of natural colorants in modern dye factories is a potential green chemistry idea that should be widely promoted to minimize the dependency of wool dyeing on some hazardous and non-biodegradable synthetic colors. In this study, an effort was undertaken to see if Rheum emodi (rhubarb) extract might be used as a natural dye for wool dyeing for the replacement of synthetic dyes. The dyeing of wool fabric was carried out using microwave (MW) ray treatment. By combining several mordants, a stunning color palette of shades of varying hues and tones was created. Comparative evaluation of the effects of various chemical mordants (aluminum salt, iron salt, tannic acid and cream of tartar) and bio-mordants (pomegranate extract and pine nut hull extract) on the characteristics of dyed wool samples was carried out to choose the best mordant for each application. It was found that MW-treated wool fabric using a bio-mordant showed a higher colorfastness value of 4/5 to 5 and a color strength value of approximately 10–20 than using metallic mordant. Scanning electron microscopy photographs and Fourier transform infrared spectroscopy analyses revealed the difference between irradiated and unirradiated wool fabrics. The employment of MW rays and bio-mordants in the natural coloring of wool fabric is encouraged due to their biocompatibility and non-toxicity when combined with MW treatment of wool fabric, as well as their high colorfastness and color strength performance. As a result, naturally extracted dyes from rhubarb can be a replacement for synthetic dyes for the coloration of wool fabric in the textile industry due to their environmental friendliness.

Siempre me ha atraído la imagen de ¡Oveja negra de la familia! Siempre he creído que hay algo trascendental en separarse de lo “normal”, de lo esperado, de responder a las expectativas, de soltar el statu quo y volar. Bert Hellinger dice que “Las llamadas ‘Ovejas Negras’ de la familia son, en realidad, buscadores natos de caminos de liberación para el árbol genealógico [...] las que no se adaptan, las que gritan rebeldía, reparan, desintoxican y crean una nueva y florecida rama”. Aquellos miembros que no se adaptan a las normas y tradiciones de un sistema cultural, social y familiar, son para mí lo que en ciencias sociales conocemos como “otros”. Esa otredad que va más allá de las líneas bien demarcadas de lo que es bueno o digno de ser estudiado o de que se le preste atención.

Authors: Eli Carmeli , Irit Grencel , Yacov Fogelman
Published: May 2023

The success of a patient's rehabilitation depends greatly on many variables. Stroke survivors are often not sufficiently or fully aware of their mental health condition, and as a result are unresponsive, frustrated, and have difficulty with executive functions. The aim was to investigate the effect of the "Golden Circle" cognitive exercise on the quality of life of post-stroke patients. The subjects were 30 volunteers at a subacute stage after an ischemic stroke. They were randomly allocated to either an experimental group (n = 15) or a control group (n = 15). Quality of life questionnaire and Visual Analogue Scale administered. They were asked to draw a circle on a blank A4 page and at the top to write a title, and within the circle to write their problems, their suggested solutions and to intuitively write associations to a color, a taste, an animal, and a general physical sensation, and below these the date. Following the intervention experimental group showed improvement in walking, standing up, daily activities and general quality of life. Using the "Golden Circle" exercise to improve self-awareness and motivation in stroke survivors contributes to coping and taking responsibility for their rehabilitation.

This paper aims to reveal how the impact of inflation on zakah can reduce the actual value of zakah collected, study the fiqh about zakah distribution, and apply zakah fund reserves funds not distributed entirely. The method used is qualitative with the form of library research (library research). This paper concludes that inflation impacts zakah acceptance; the amount of zakah collected is reduced. The management of zakah by the state in some scholars’ reviews turns out to have a more significant positive impact than if zakah is distributed individually by muzaki. The rule regarding zakah funds reserves, in distributing zakah during the time of the Prophet ﷺ is never to delay the distribution of zakah, the zakah received is then distributed to the asnaf, so that the nature of zakah distribution during the time of the Prophet ﷺ is immediately and distributed without remainder.

Chronic pain syndrome developing in patients with oncological diseases significantly decreases their quality of life which makes effective integrative analgetic therapy a pressing issue. Currently, drugs of various pharmaceutical groups are used for pain management and administered subsequentially in accordance with the pain intensity visual analogue scale. For moderate and severe pain syndrome, opioid analgesics are used which have side effects limiting their use in some cases. Trials showed that new highly specific μ1-opioid receptor agonist tafalgin is characterized by high bioavailability, fast absorption, biotransformation, absence of accumulation which makes its safety profile favorable. Pronounced analgesic effect of tafalgin, as well as ease of administration and absence of significant adverse events, allow to significantly improve the quality of life of patients with chronic pain syndrome.

In order to ensure safe operation of buildings in undermined areas, it is necessary to take into account the influence of loads extrinsic to typical structures. The solution of the generalized boundary value problem on the evaluation of the stress-strain state (SSS) of the building–foundation–soil system with due regard for the complete geometry and physically nonlinear behavior of all the elements is inexpedient since it is complicated by the large dimensionality of the problem. This paper discusses an approach allowing the state of monolithic reinforced concrete building structures located in an undermined area to be estimated by solving boundary value problems on different scales, from modeling the whole system in an elastic formulation to modeling joints between load-bearing members (columns and floors) in a nonlinear formulation for concrete and reinforcement. In these problems, strain energy is taken as the parameter characterizing the deformation process at critical deformation stages and connecting the boundary value problems. The obtained loading diagrams for a unit and the evaluation of the SSS of the whole structure enable one to find the values of maximum permissible horizontal soil deformations in the vicinity of the foundation, at which the bearing members reach the SSS preceding the loss of bearing capacity.
Plasma adiponectin as a predictor of the effectiveness of coronary heart disease therapy in patients with metabolic syndrome
Authors: Firova Elvira M. , Tanyanskiy Dmitry A.
Published: May 2023

BACKGROUND: Adiponectin, an adipose tissue protein, plays a crucial role in the development of metabolic syndrome and atherosclerosis. As a potential therapeutic target, this adipokine can be considered in the context of treatment strategies.
AIM: The aim of this study was to assess the correlation between changes in plasma adiponectin concentration during coronary heart disease therapy and the effectiveness of the treatment, as well as to examine the relationship between initial adiponectin levels and treatment outcomes in patients with metabolic syndrome.
MATERIALS AND METHODS: The study included 31 patients with coronary heart disease and metabolic syndrome (age 59.7 5.9 years, 21 women) which underwent the reexamination after 23 years. Most patients received statins (n = 26), while some received fibrates (n = 4) and hypoglycemic drugs (n = 4). Additionally, the patients were on hypotensive and antithrombotic therapies. The effectiveness of coronary heart disease therapy was assessed by evaluating changes in the functional class of angina pectoris and exercise tolerance measured through cycle ergometry. Plasma samples were collected at the initial and reexamination periods to determine glucose, insulin, adiponectin, leptin, and lipidogram parameters.
RESULTS: The study revealed improvements in insulin sensitivity and plasma lipid spectrum, along with reduced levels of plasma leptin and increased adiponectin levels during the course of therapy. In addition, some patients showed enhanced exercise tolerance. Among the biochemical parameters, changes in insulin resistance during therapy correlated with improvements in exercise performance indicators during cycle ergometry (r = 0.320.36, p 0.05). Moreover, multiple regression analysis indicated that the initial adiponectin concentration independently determined changes in inotropic reserve and the amount of work performed ( = 0.44, p = 0.04 and = 0.64, p = 0.008).
CONCLUSIONS: The studys findings regarding the association of plasma adiponectin concentration with changes in exercise tolerance during coronary heart disease therapy suggest the potential for developing specific approaches to raise adiponectin levels in the future.
Simulation of Low-Frequency Waves Propagating along Water Service Pipelines
Authors:   , Hasan Fatmah , Bartoli Ivan
Published: May 2023

The material of water service pipelines is of crucial concern to the public health. Some materials including lead can lead to serious health diseases. Unfortunately, lead has been widely used for water service pipelines in the 1900s. Currently, identification of the material of the pipes is challenging since it requires costly excavation. Consequently, developing a new non-destructive method which allows us to easily distinguish between the materials is important. In this research, guided waves concept is considered as a possible tool to non destructively identify the material of buried pipelines. Simulations of wave propagation in pipes has been done in ABAQUS to extract the dispersion curves of pipe made of different materials and to explore possible guided modes that could be adopted to identify the material of service lines. Simulations have been completed using ABAQUS EXPLICIT to represent wave propagation in the water service pipelines. A Two-dimensional Fourier Transform is used to analyze time histories obtained by ABAQUS to extract the dispersion curves. The hypothesis is that by extracting the phase velocity of buried pipes in a given frequency range, classification of the various materials could be attempted. The suggested method provides promising results. However, there are few limitations and challenges. For empty pipes in vacuum, the phase velocity dispersion curves are easily extracted. When the pipe is filled with water, a small amount of energy will dissipate into the water region reducing the excitability of some modes. In the case of buried pipes, soil will pose multiple challenges as the energy carried along buried pipes will leak into the surrounding medium causing significant wave attenuation.
Social Network Analysis of a Physics Faculty Online Learning Community
Authors:   , Hatcher Chase Wootton , Brewe Eric
Published: May 2023

Community-based professional development initiatives have been shown to support physics faculty in their adoption of research-based instructional strategies. Hoping to better understand these initiatives' mechanisms of success, we analyze the results of two surveys administered to a faculty online learning community teaching a common physics curriculum designed primarily for pre-service elementary teachers. We use social network analysis to represent the faculty network and compare members' centrality, a family of measures that capture the prominence of individuals within a network, to their reported experience in the community. We use a principal component analysis of different centrality measures to show that closeness, a measure of how closely connected a person is with every other person in their network, is the most appropriate centrality measure for our network. We then compare regression models according to Bayes factors to find relationships between participants' closeness and their survey responses. We find that participants' self-efficacy for instructional leadership, as well as their sense of improvement to their teaching and sense of benefitting from the community, are related to their closeness with other participants and thus their breadth and depth of participation in the community. Our results are consistent with other studies that have highlighted interactions among faculty as key components of successful professional development initiatives. They may also be useful for designers of similar communities as they decide how to prioritize time and resources to meet specific goals.

Published: May 2023

In this study, the validity of the estimation of a single regression equation for the diffuse frac-tion across 22 stations in India using the two parameters: the clearness index and the sunshine ratio is tested. The homogeneity test based on Fisher’s statistics was applied to test the homo-geneity of the estimated parameters across all stations. The results showed that the p-value at the level of 5% for each model is smaller than 0.05, indicating that all stations were heteroge-neous. The Hierarchical Cluster Analysis (HCA) was used to classify the data into homoge-nous clusters. The results of HCA indicated that the longitudinal data were divided into four main clusters. For each cluster, the regression analysis was applied based on the longitudinal data then, the fixed effects model (FEM) and the random-effects model (REM) were used for the evaluation. Further, the Hausman test was applied to choose between the fixed effects model and the random-effects model. Finally, the results showed that the four best regression models were found for the selected stations in the study area.

Published: May 2023

В данной статье рассмотрены некоторые элементы технологии возделывания нута, влияние способов посева и норм высева на продолжительность межфазных периодов перспективных сортов. Важным условием формирования высоких урожаев нута является линейный рост растений в посевах. Формирование линейного роста определяется генетическим потенциалом, растений и зависит от имеющихся запасов влаги в почве, уровня минерального питания и плотности посева. Заметные различия высоты растений по вариантам опыта стали проявляться в фазу бутонизации. Высота растений в этой фазе развития нута изменялась в пределах 16,5 - 32,6 см, в зависимости от водообеспеченности.

На сегодняшний день, как и всегда было, строительство является одной из основных системообразующих сфер человеческой деятельности. Строительная отрасль сегодня покрывает практически каждый уголок нашей планеты, будь то жаркая пустыня или Тихий океан. Исключением не является и северная часть нашей страны. Это территория, на которой основным видом грунта является вечная мерзлота. Стоит отметить, что общая площадь вечномерзлых грунтов составляет около 65% всей площади России. Именно поэтому, когда речь идет о строительстве в таких районах, на первое место выходит вопрос термостабилизации грунтов. Данный вопрос требует больших капиталовложений для обустройства месторождений полезных ископаемых, организации их инфраструктуры, а также строительства объектов гражданского, военного и специального назначения. В данной статье будет рассмотрен вопрос термостабилизации грунтов, а также рассмотрены возможные методы его решения.

We have carried out the rehabilitation of a patient after a traumatic injury to the maxillofacial region resulting from the explosion of an electronic cigarette. The patient was treated in the Department of Maxillofacial Surgery of the Republican Children's Clinical Hospital in Ufa. A 16-year-old boy was delivered by an ambulance to the emergency department of the Republican Children's Clinical Hospital in Ufa 30 minutes after the injury. The child was hospitalized in the department of maxillofacial surgery. At stage I, primary surgical treatment was performed, reposition of the free-lying fragment of the upper jaw in the frontal section and fixation of the mucosa of the alveolar process of the upper jaw in the region of 1.3 and 2.4 teeth with vicryl 2.0. The mucosa was mobilized along the transitional fold of the upper jaw in the anterior region, placed in the region of the defect in the upper jaw, and sutured with a 5-0 Vicryl thread. After 6 months, the patient enters the II stage of surgical treatment. The cortical plates were placed in the area of the defect and fixed with titanium screws. After another 6 months, the child enters the III stage of surgical treatment - the removal of titanium screws, the installation of dental implants. Stage IV. Installation of temporary crowns of teeth.
As a result of smoking a vape, a teenager received severe traumatic stress. Stage IV of complex surgical treatment was carried out. There are stages of implant prosthetics, which is quite expensive for the patient, since this treatment is not included in the List of State Guarantees. Undoubtedly, vape smoking is a very cost-effective procedure, and very harmful to health in general.

The problem of studying the prevalence of dentofacial abnormalities in children in the Sverdlovsk region is relevant, as the data for different regions are differ, which is confirmed by the heterogeneity of indicators and statistics in the research. In 2022, an epidemiological study was conducted among the children's population of 4 cities of the Sverdlovsk region to study the prevalence of dentofacial abnormalities in the age groups 3–5, 6, 12 and 15 years, a total of 455 children were examined. Registration of dentofacial abnormalities was carried out in the author's card of dentofacial system disorders developed, using the classifications of MGMSU and ICD-10. Statistical processing of the data obtained was carried out in STATISTICA 13.3. The study revealed a high prevalence of dentofacial abnormalities in children in the Sverdlovsk region – 71.43% ± 2.12. With age, there is a tendency to increase the frequency of dentofacial abnormalities: in children 3–5 years of dentofacial abnormalities were in 34.85% ± 5.87 cases; in the group of 6-year-olds – in 70.18% ± 4.28; and in groups of 12-year-old and 15-year-old children – 81.38% ± 3.23 and 80.00%. It was revealed that the older the children are, the more likely they have severe malocclusion compared to children aged 3–5 and 6. The groups noted high rates of dentition deformities, the number of which also increases with age (decrease in the length of the upper dentition was detected in 36.26% ± 2.25, the lower dentition – in 47.47% ± 2.34 of cases; narrowing of the upper dentition – in 55.60 ± 2.33%, lower dentition – in 45.49% ± 2.33 of cases). Dentition deformities are associated with the development of teeth abnormalities, such as teeth retention (13.10% ± 2.80 and 9.23% ± 2.54 of cases in 12- and 15-year-old children, respectively), as well as mandibular displacement (displacement to the side was detected in 22.20% ± 1.95 of cases). Performed study is justification for the development and implementation of a regional program for the prevention of dental diseases in children of the Sverdlovsk region.
