Diário de Luanda e o Festival Carnavalesco de 1937
Authors: Marzano Andrea
Published: December 2023

O tema deste artigo é um festival carnavalesco organizado, em 1937, por iniciativa do Diário de Luanda. Pretende-se investigar de que forma o festival, e suas representações na imprensa, espraiaram, na capital da colônia de Angola, elementos centrais do modelo corporativo e da propaganda salazarista, que tinha lugar, na metrópole, através da realização de grandes eventos, como desfiles de marchas populares e exposições. Em matérias jornalísticas sobre o festival, pretende-se demonstrar representações orgânicas, harmônicas e hierarquizadas da sociedade, condizentes com os princípios do corporativismo; a exibição de símbolos do progresso social e industrial, que justificariam a presença colonial; a divulgação de uma imagem mítica, atemporal e heroica do povo português, fadado, desde tempos imemoriais, a levar a civilização aos trópicos; e a valorização de costumes regionais, entendidos como manifestações folclóricas que comporiam um todo indivisível, caracterizado como o “mundo português”.

Published: December 2023

Introduction. During one-stage mincing of frozen meat by milling, a change in the temperature of the boundary layer occurs resulting in plastic deformations of the raw meat and an increase in the size of the meat chips. The problem of regulating the operating parameters for the raw meat mincing process depending on its temperature can be solved through computer calculations of the temperature forecast of the meat boundary layer for several time intervals using fuzzy logic. The aim of the study was to develop an algorithm for hybrid control of single-stage mincing of frozen meat using fuzzy and clear mathematical control models.
Aim of the Article. The article is aimed at developing a hybrid control algorithm for singlestage grinding of frozen meat using fuzzy and clear mathematical control models.
Materials and Methods. The object of the study was the process of mincing frozen meat block (beef) with the use of a laboratory installation for a single-stage mincing with a capacity of 400 kg/hour. The E. Mamdani algorithm was used to develop a fuzzy mathematical control model. Mathematical modeling was carried out in the MATLAB, the Fuzzy Logic Toolbox package.
Results. There was developed a model for fuzzy control of the operation of an intelligent control system (ICS) when forming a task for setting the operating parameters of the meat mincing process with the use of adaptive forecasting of meat temperature. For this model, the membership functions of the input and output variables and a rule base (knowledge base) were created. There was proposed a functional scheme of temperature control, which reflects the structure of a fuzzy control model for single-stage mincing. The advantages of this control include the fact that the system is given the function of continuous automated control of the temperature regime of mincing raw meat under the control of an industrial computer.
Discussion and Conclusion. The results of temperature control can be used for further technological processing of meat. Using information about the temperature and chemical composition of raw meat, the ICS can realize the optimal mixing of minced meat ingredients. Artificial intelligence calculates all these characteristics of meat without the participation of a human operator. It makes it possible to fully automate the technological processing of meat in order to produce finished products of guaranteed high quality.
Gestaltungsprinzipien spätantiker Grabräume
Authors: Fugger Verena
Published: December 2023

Die vorliegende Untersuchung eröffnet eine völlig neue Perspektive auf die römische Katakombenmalerei. Als Schlüsselmonumente der Christlichen Archäologie stehen die Katakomben Roms seit ihrer Wiederentdeckung immer wieder im Fokus der Forschung. Dennoch sind übergreifende Fragestellungen zur konzeptionellen Gestaltung ihrer mit Malereien dekorierten Grabmäler bislang kaum behandelt worden. Diese Forschungslücke greift die Studie auf und arbeitet auf umfassender Materialbasis heraus, welche leitenden Prinzipien bei der malerischen Ausstattung christlicher Grabräume im 3. und 4. Jahrhundert n. Chr. bestimmend waren. Mithilfe eines bildwissenschaftlich-rezeptionsästhetisch orientierten Zugangs, der die Wechselbeziehung zwischen Raum, Bild und Betrachter in den Vordergrund stellt, werden die Anordnung und Kombination von Motiven erstmals systematisch untersucht und semantische Strukturen im Zusammenspiel der Bilder sichtbar gemacht. Die Studie kommt dabei zu dem erstaunlichen Ergebnis, dass sich der Umgang mit Bildern am Grab keineswegs beliebig gestaltete. Vielmehr werden bestimmte Regelmäßigkeiten greifbar, die sich auch an zeitgenössischen Grabmälern in anderen Regionen des Römischen Reiches wiederfinden lassen.
A comparison of performances of Brazilian and Chinese Universities in academic and industrial products using the “U-Multirank”
Authors: Prado Antonio
Published: December 2023

Background and aims

The present work studies the performances of Brazilian and Chinese Universities considering academic and industrial related products. A comparison of the behavior of Universities that belong to these two countries are important, because they have similar characteristics and both of them are considered to be emergent countries, being part of the group known as BRICS.

Methods

The data is obtained from the “U-Multirank” in the years from 2017 to 2020, which are recent, but not yet affected by the pandemic, since the results for the year 2020 were obtained in 2019. This ranking used 36 Indicators in those years, with some of them related to academic production (number of papers published, citations received by the papers, etc); while some others are related to industrial products (number of patents obtained, citations made in patents, etc). This analysis is made for the average performances of Brazilian, Chinese and all the universities listed in the “U-Multirank” in the years under study.

Results

The results show the number of institutions listed every year and the average grades of Brazilian and Chinese institutions, as well as the world averages, in all the Indicators studied.

Conclusions

The results show that Chinese Institutions have a good balance in terms of quantity and quality of academic researches, with both numbers ahead of world averages. Brazil is better in quantity of publications compared to quality, having grades similar to China in number of publications and well above world averages, but the indicators “Citation Rate” and “Top-cited” publications are well below world and Chinese averages.

Published: December 2023

The decline in seahorse populations in the wild due to high fishing activity and habitat degradation prompted the inclusion of all seahorse species in Appendix II of CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) in 2002. By being included in Appendix II of CITES, data and information on the abundance of seahorse populations become crucial as the basis for determining the quota for fishing and trade. Estimating population abundance of seahorse requires knowledge of habitat area, which can be modeled using the MaxEnt (maximum entropty). In this study, an estimation of the abundance of seahorses was carried out in the waters of Sebong Bay, Bintan Island. MaxEnt modeling was implemented with data on seahorse presence locations and environmental parameter maps consisting of chlorophyll-a as primary productivity parameter, benthic habitat as habitat type parameter, and dissolved oxygen, salinity, and pH as physiological parameters. From this model, the value of the area of suitable habitat for seahorses is 54,6 ha, while the density of seahorse in this area is 60 ind/ha, so it can be determined that the abundance of seahorses in the Sebong Bay is 3.276 individuals. Therefore, seahorse population in Sebong Bay is critically endangered since it is below the number of individuals that required to prevent the loss of quantitative genetic variation in a species.

Published: December 2023

Fish scales have a fairly high protein content, one of which is collagen. Therefore, it is necessary to conduct research related to the use of fish scales as gelatine, which is one of the collagen derivative products. This study used a completely randomized design consisting of 5 treatments of vinegar concentration, namely 10% palm vinegar immersion, 20%, 30%, 40%, 50%. The results showed that the protein content of gelatin from fish scales ranged from 39.95–47.35%, with the lowest protein content in the 10% lontar vinegar treatment, which was 39.95, while the highest protein content was at the 40% lontar vinegar concentration, which reached 47.35%. The average ash content of fish scale gelatin produced in this study was in the range of 46.58%–50.20%, with the lowest ash content found in the 50% palm vinegar pre-treatment, which was 46.58%. On the other hand, the highest ash content was at 30% vinegar concentration, which reached 50.2%. The results of functional group analysis showed that there was absorption of amide A, amide I, amide II, and amide III groups, indicating that the resulting product was gelatin. The most optimal treatment of palm vinegar concentration in this study was found at 40% palm vinegar concentration, namely 48.11% ash content and 47.35% protein, although the protein content did not meet commercial gelatin standards.

Published: December 2023

The increase in aquaculture production must be accompanied by effective and efficient feed, thus requiring innovation to obtain the appropriate feed ingredients. This research aims to determine the effect of maggot meal and commercial eel feed on the growth, protein digestibility, and production cost of eel (Anguilla bicolor bicolor) aquaculture. Eels were reared in 15 aquariums measuring 60 × 40 × 40 cm, equipped with water filters, with five treatments and three replications. The treatments consisted of maggot meal + eel feed in the following proportions: A1 (0% + 100%), A2 (25% + 75%), A3 (50% + 50%), A4 (75% + 25%), and A5 (100% + 0%). The feed was given twice a day, morning and afternoon, according to the requirements. Data on growth rate and feed efficiency were collected every two weeks, while protein digestibility and production cost were calculated at the end of the 60-day study period. Treatment A2 showed a daily growth rate of 1.218±0.409%, which approached the growth rate of the commercial feed treatment (A1). Treatment A5 had a growth rate of 0.309±0.218% per day, while treatment A1 had a growth rate of 1.440±0.364%. The best feed conversion ratio (FCR) in each phase was obtained in treatment A1, with a value of 1.862±0.086. The highest FCR was found in treatment A5, with a value of 6.455±1.158 in each phase. The best feed efficiency was observed in treatment A2 at 82.79%, while the lowest digestibility was in treatment A4 at 34.88%. The digestibility of feed in treatment A2 was the highest at 58.42%. According to the research findings, the production cost per kilogram of eel was more cost-effective and required less time in treatment A2, with a feed cost of Rp 105,000/kg. The utilization of a combination of maggot meal and commercial feed shows potential as a feed that can be used to enhance growth rate.

Engaging adolescents’ negative emotional experiences as a resource for decision-making
Authors: Magnusson Simon
Published: December 2023

In this study, youth participation in a participatory democracy project is examined at the intersection of the deontic and emotional order. The data are drawn from a yearlong participatory democracy project where 14–15-year-olds meet with politicians and public servants to decide on a vision for how the community should be in 2050. By analysing their interactions, the present study shows how adult community representatives elicit adolescents’ negative emotional experiences and transform these into deontic building blocks in the impending decision-making. The analysis shows how the transformation of adolescents’ negative emotional experiences casts the adolescents as emotional perceivers and deontic objects, a role they are shown to comply with. Furthermore, this sets up a proximal deontic order that, in turn, re-establishes a distal deontic order, both in which the adolescents’ positions are subordinated and regulated. Ultimately, by inviting youths to participate in the democracy project itself as well as eliciting their negative emotional experiences the politicians and public servants are shown to use the youths as emotional gearwheels in an already set larger deontic machinery.
Sign language socialization and participant frameworks in three indigenous Mesoamerican communities
Authors: Horton Laura , Hou Lynn , German Austin , Singleton Jenny
Published: December 2023

This article provides a cross-cultural study of language socialization through sign language in three indigenous Mesoamerican communities. We explore whether child signers are socialized to use visual communicative practices as participants or observers. We present four conversations that illustrate how child signers are socialized into these practices. Child signers in our study acquire appropriate visual practices, even when they are primarily observers. But sign language socialization practices may be distinct from broader patterns of spoken language socialization in terms of participant frameworks. We find that recognition of child signers as full participants in sign conversation is shaped by a constellation of local child-rearing beliefs and language ecology dynamics.
Restraining the Senses and Relations of Care
Authors: Smith Caley Charles
Published: December 2023

This article puts late Vedic ritual and the renouncer and householder traditions of early South Asia into dialogue in a new way, by thinking about restraining the senses through the etic lens of regimes of care. Guiding questions in this study are: (1) How do regimes of care help us understand the conceptual interface of violence, restraint, purity and community? (2) How do shifting relations of care help us understand conceptual change over time? Finally, (3) how does conceptual change help us speculate productively about changes in relations of care? The clear thematic bifurcation in the texts will recapitulate what Nathan McGovern has termed a ‘broad, trans-sectarian tension between renunciate and householder lifestyles’.

Published: December 2023

This work entitled Facewords. Word formation trends in social media adds to the body of work focussing on the latest trends in the Polish language. The primary goal of this research is to observe changes in word formation in the language of contemporary social media. The raw ata is derived from excerpts from online comments posted on Facebook in fanpages of popular socio-political press titles: Gazeta Wyborcza, Fronda, Newsweek and Wprost. The collected lexical material comes from the years 2013–2018. Word formations within two parts of speech were analysed: the noun and the adjective. The set of discussed items includes both existing derivatives, well embedded in the lexical resource of the general language, as well as new items which are yet to be recorded in general Polish dictionaries. The comparison of these two groups of derivatives allows us to answer the question of what kind of word-formation techniques are most often applied in the language of the Internet. The main part of the work is a chapter devoted to the analysis of the derivatives of noun and adjective word-formation. Pronounced lexemes are characterized in terms of the word-formation techniques used to create tchem (prefixing, suffixing, negative derivation, paradigmatic, alternating). Simple derivatives and assemblies, adhesions and contamination were discussed. The analysed lexemes were assigned to the appropriate word formation categories. The description includes a broadly understood social and communication context. The summary highlights the most important trends in word-formation of the language of contemporary electronic media.

Authors: CAVUSOGLU Aysun
Published: December 2023

This experiment was undertaken to determine the adaptation of Lilium L. cultivars to North-Western part of Türkiye and to define morphologic plant growth characteristics at aboveground part, including flower life and flower abnormalities. The bulbs of the three Lilium L. cultivars, ‘Profundo’, ‘Valverde’, and ‘Vonq’, were sown to perlite in pots in June, 2021, and evaluated for emergence and flowering rates, stem and plant height, stem and flower diameter, leaf and flower number, flower abnormality rates, flower fragrance degree and flower life in 2022, after one year adaptation without removing the previous sown bulbs. As the results of the cultivars differences these were determined that, at the adaptive year; the emergence rates varied between 60.42-89.58%, flowering rates changed between 43.75-87.50%, stem heights changed between 40.63-48.25 cm, plant heights changed between 52.50-59.75 cm and these data showed statistically importance. In addition to the data in the adaptive year; stem diameters, leaf numbers, flower numbers flower fragrance degree and flower longevities also showed statistical importance between cultivars. The flower abnormality rates were found between 8.3-25% in cultivars although no statistical results. Interestingly a striking, stochastic case also was observed from a flower with 8 tepals, 8 stamen and 4 lobed stigma at ‘Valverde’ contrary to well-known flower formula. It has been concluded that ‘Profundo’ has more remarkable result in terms of longevity of flower compared to the other two varieties while ‘Valverde’ and ‘Vonq’ shared the same group with some precedence in most of the agro-morphologic characteristics e.g. plant height, stem height and stem diameter. Lilium L. ‘Vonq’ showed that the highest adaptive capacity among the cultivars with the highest emergence rate (89.58) in all sowed bulbs and flowering rate (87.50) in all emerged bulbs under the study conditions in the open-air.

Published: December 2023

In Santorini Island, Greece, the research and revival of cultivation techniques are crucial to the adaptation of viticulture in the current unique and extreme climatic and cultural conditions, including the increasingly extreme climatic phenomena resulting from climate change. This work presents the use of cover crops, in a new planting and productive Assyrtiko vineyard in Santorin Island. Our study is the first reflection of the use of cover crops in the special conditions of the island to mitigate wind and sandblasting damages and reduce high ground temperatures during days with high temperatures. We showed that the use of cover crops could play a significant role in reducing the wind speed and the resulting sandblasting that cause almost every year damage to young and productive vines when they are at critical growth stages.

Published: December 2023

The MADS-box family genes are involved in the development of plant roots, leaves, flowers, and fruits, and play a crucial role in plant growth and development. Studying MADS-box genes with K-box domain is crucial to distinguish different types of MADS-box genes. This study systematically analysed the genomic structural information of maize MADS-box family members containing the K-box Domain at the genome-wide level using the maize (Zea mays) B73 genome as the reference sequence, and provided insight into the biological functions of the maize MADS-box family containing the K-box domain. According to the findings, 52 MADS-box family genes with K-box domain were identified and divided into 4 subgroups. The distribution of motif in the same subgroup was found to be relatively conservative, and all of them had MADS-box conserved domain and K-box domain. Gene structure analysis showed that the introns and exons of the same subgroup genes have similar gene structure, and different types of genes containing the K-box domain showed different exon/intron structure characteristics. Chromosome mapping showed that 52 genes containing the K-box domain were unevenly distributed on the 10 chromosomes of maize, most of which were distributed at both ends of the chromosome and a small number of genes were distributed near the centromere. Based on the analysis of cis-acting elements of it up-stream promoter, it was found that MADS-box family genes may be involved in light response, IAA, GA, ABA, and LTR signal pathways, indicating that they play a certain role in stress response and hormone signal transduction. The expression analysis of genes with the K-box domain in maize leaves treated with auxin and gibberellin revealed that MADS-box genes may have a regulatory effect on certain plant hormones. Through the identification and bioinformatics analysis of MADS-box family genes containing the K-box domain, it is helpful to further study the function and pathway of MADS-box family genes, and provide a theoretical basis for further re-search for the molecular mechanism of maize growth and development.
Improving quality parameters of spinach by adjusting light spectra under moderate water deprivation conditions

Published: December 2023

Spinach (Spinacia oleracea L.) is a highly valuable leafy vegetable, abundant in vitamins, minerals, and antioxidants, offering various health benefits such as enhancing cardiovascular health, reducing inflammation, and aiding digestion. Consequently, it is crucial to effectively cultivate and maintain spinach's quality. Light plays a pivotal role in the growth and development of plants, including spinach, where different light qualities can influence its morpho-physiological traits and overall quality. To explore this, an experiment was conducted, using three distinct LED lighting sets for spinach cultivation. Light 1 emphasized blue light, Light 2 served as the standard white light control, and Light 3 focused more on red light with occasional brief UV-C flashes. Additionally, mild water deprivation was induced using 2.5% polyethylene glycol (PEG). The results revealed that using a high red-to-blue light ratio with intermittent UV-C radiation significantly reduced various growth parameters of spinach, such as root length, shoot length, root volume, fresh and dry root and shoot weight, as well as total and relative chlorophyll contents, when compared to the control group. Furthermore, water deprivation had a negative impact on spinach's growth, affecting shoot and root length, and fresh and dry weight in all light qualities, proving to be fatal under Light 3 conditions. Therefore, it is essential to carefully select appropriate light qualities throughout the plant's life cycle to enhance the quality of spinach, especially when mild water deprivation is involved. Opting for a higher blue-to-red light ratio was found to be somewhat beneficial in improving the overall quality of spinach.

The low availability of micronutrients in the soil leads to a deficit of these micronutrients in crops, causing malnutrition in the population. Approximately 3,000 million people in the world have health problems caused by inadequate Zn intake. Agronomic biofortification is a way to produce crops rich in micronutrients and mitigate malnutrition problems. Nano biofortification with zinc oxide nanoparticles (NPs-ZnO) is a good strategy to mitigate and increase the nutritional content of the edible part of the plant. The aim was to determine the effect of foliar spraying with NPs-ZnO on yield and biosynthesis of enzymatic and non-enzymatic antioxidant compounds and their bioaccumulation. In this study, the effect of foliar fertilization with NPs-ZnO: 0, 25, 50, 75, and 100 mg L-1, on yield, the content of bioactive compounds and their bioaccumulation in grapevine berries was evaluated. The distribution of the treatments was under a completely randomized design, each treatment consisted of 10 plants, each representing one experimental unit. The treatments were applied by foliar sprays at fruit formation, in veraison and 15 days before harvest. Foliar spraying with NPs-ZnO positively modifies yield, the content of bioactive compounds, and their bioaccumulation. Doses of 50-75 mg L-1 of NPs-ZnO increased crop yield, and oenological parameters. In addition, all doses evaluated modified enzymatic and non-enzymatic antioxidants, and improving Zn concentration in grapevine berries. Foliar spraying of NPs-ZnO is an alternative to improve grape quality and yield, in addition to enriching its nutritional and antioxidant content.

Published: December 2023

Cereal crops are essential for providing essential nutrients and energy in the daily human diet. Additionally, they have a crucial role as a significant constituent of cattle feed, hence enhancing meat production. Drought, being an abiotic stressor, adversely affects the growth and yield of numerous crops on a global scale. This issue poses a significant and pressing obstacle to maintaining global cereal crop production and ensuring food security. Nanoparticles have become a valuable resource for improving cereal crop yield and productivity under ongoing rapid climate change and escalating drought conditions. Among these, silica nanoparticles (SiNPs) have demonstrated their potential for agricultural applications in regions with limited water availability. Drought stress has detrimental effects on cereal crops, impacting their growth, metabolic, and physiological processes, hampering water and nutrient absorption, disrupting cellular membranes, damaging the photosynthetic apparatus, and reducing antioxidant activities by altering gene expression. SiNPs help preserve cellular membranes, regulate water balance, and improve water and nutrient absorption, resulting in a substantial enhancement in plant growth under water-deficit conditions. SiNPs also protect the photosynthetic system and enhance its efficiency, facilitate the accumulation of phenolics, hormones, osmolytes, antioxidant activities, and gene expression, thus empowering plants with increased resistance to drought stress. Moreover, SiNPs decrease leaf water loss by promoting stomatal closure, primarily by fostering the accumulation of abscisic acid (ABA) and mitigating oxidative stress damage by activating the antioxidant defence system and reducing reactive oxygen species (ROS). However, a limited number of studies examine the role of SiNPs in cereal crops under drought stress conditions. In this review, we highlighted the promising potential of SiNPs to improve cereal crop resilience by changing morpho-histological traits, antioxidant properties, and gene expression to maintain food security in drought-prone areas. This study will aid researchers in using SiNPs as an environmentally benign way to improving drought resistance in cereal crops in order to fulfill global food supply needs.
Water ecological requirements of Characeae taxa in eastern Spain
Authors: SANZ Borja , FERRIOL María , BOIRA Herminio
Published: December 2023

Presence of Characeae taxa is limited by the existence of clear and oligotrophic waters. Some other chemical water parameters can also influence the distribution of taxa, which can thus be used as ecological bioindicators. The area of eastern Spain contains a high diversity of water basins in both coastal and inland habitats that allow the study of ecological gradients. This work aimed to identify the most relevant and significant water chemical parameters that determine the distribution of Characeae taxa, and establish their optima and tolerance ranges for each parameter in eastern Spain. Ninety-six records corresponding to unpublished old and recent samplings of the presence of 17 taxa belonging to the genera Chara, Nitella, Tolypella and Lamprothamnium were related to water parameters that included salinity, pH, electric conductivity, total water hardness, alkalinity, concentrations of Na+, Mg2+, Ca2+, Cl-, and SO42-, and Mg2+/Ca2+ ratio. Principal Component Analysis showed that salinity was the major factor that determined the distribution of Characeae taxa, followed by concentration of Mg2+, Mg2+/Ca2+ ratio and alkalinity. When previously published records from the same area were added, non-parametric tests showed significant differences among taxa only for salinity, water hardness, and Mg2+/Ca2+ ratio. These statistical analyses, along with optima and tolerance ranges for each parameter showed that Characeae taxa, especially Lamprothamnium papulosum and Tolypella spp., could be used as bioindicators in eastern Spain, although their ecological differentiation is not clear in many cases.

Abstract Gels containing juca seed galactomannan (JSG) were evaluated for their potential to prevent the progression of dentin erosive wear in an in vitro study with four experimental groups (n = 9). The treatments included distilled water (DW), 0.05% stannous fluoride (121 ppm F), and 0.5% or 1% JSG. The specimens underwent a cycle (3 times/day) consisting of immersion in 1% citric acid (5 minutes), treatment (5 minutes), and artificial saliva exposure (2 hours/overnight) for 5 days. Surface changes were assessed using mechanical profilometry (wear), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). The data were analyzed using ANOVA followed by Tukey's post-test (p < 0.05). The negative control group exhibited the highest wear (6.0 µm ± 3.5), significantly differing from the group treated with 0.05% stannous fluoride gel (p = 0.007), which showed less dentin loss. The groups treated with 0.5% and 1% JSG showed results similar to the negative control (p = 0.661; p = 0.212, respectively) and the stannous fluoride group (p = 0.103; p = 0.379, respectively). In the SEM images, the specimen treated with stannous fluoride showed obliterated tubules, while the JSG gels formed crystals on the dentin surface, as confirmed by the presence of oxygen and calcium in the EDS analysis. Although the JSG gels showed similar results to the stannous fluoride, did not exhibit superior efficacy at the tested concentrations.

Abstract This study evaluated the efficacy of incorporating different concentrations of bioactive glass-ceramic (Biosilicate) into coconut oil on the remineralizing potential and surface roughness of white spot lesions. Fragments (6 x 6 x 2mm) of bovine teeth were sectioned and initial microhardness (KHN) and surface roughness (Ra) readings were obtained. The samples were submitted to cariogenic challenge to form white spot lesions and were separated into six groups (n=13): 1) Artificial Saliva (AS); 2) Coconut Oil (CO); 3) CO+2% Biosilicate (CO+2%Bio); 4) CO+5% Biosilicate (CO+5%Bio); 5) 2% Biosilicate Suspension (2% Bio) and 6) 5% Biosilicate Suspension (5% Bio). The treatments for 1 cycle/day were: immersion into the treatments for 5 minutes, rinsing in distilled water, and storage in artificial saliva at 37ºC. After 14 days, KHN and Ra readings were taken. The surface roughness alteration ((Ra) was analyzed (Kruskal-Wallis, Dunn’s post-test, p<0.05). CO+2%Bio had higher (p = 0.0013) (Ra followed by CO+5%Bio (p = 0.0244) than AS. The relative KHN and remineralization potential were analyzed (ANOVA, Tukey, p<0.05), and 5% Bio treatment presented a higher relative microhardness than all other groups (p>0.05). The remineralizing potential of all the treatments was similar (p > .05). When Biosilicate was added, the pH of the suspensions increased and the alkaline pH remained during the analysis. Biosilicate suspension is more efficient than the incorporation of particles into coconut oil at white spot lesion treatment. In addition to the benefits that coconut oil and Biosilicate present separately, their association can enhance the remineralizing potential of Biosilicate.

Abstract This study evaluated a method to determine the spatial geometry of root canal preparation (RCP) using navigation dynamics and a specific algorithm from a new CBCT software (e-Vol DX). CBCT scans of 168 root canals of mandibular molars were acquired before and after RCP, using nickel-titanium (NiTi) instruments (ProTaper Next, BioRace, Reciproc Blue, and WaveOne Gold). The spatial geometry of the root canals and the operative risk of disproportional wear of dentinal walls after RCP were evaluated using a new CBCT software. A 3-point scoring system was used after the measuring of cementum/dentin thickness before and after RCP in all root thirds. The root thirds were distributed into three parts of similar sizes, and the scores were categorized at three levels: 1. mild risk (1/3), 2. moderate risk (2/3), 3. severe risk (3/3). These levels were proposed according to the risk of creating disproportionate shapes, thin walls, or perforations. The data were analyzed statistically by Fischer’s exact test (α = 5%). There were no significant differences in operative risk among the NiTi engine-driven systems, for the distal or mesial walls of all the root canal thirds (p>0.05). The spatial geometry method to assess operative risk allows clinical planning for a predictable enlargement of the root canal in all root thirds. Based on using a map-reading strategy on root canals in CBCT scans, NiTi engine-driven instruments did not present an increased operative risk during RCPs.

Abstract This study aims to evaluate the fatigue resistance of monolithic zirconia (Yz) and multilayer ceramic structures using the CAD-on technique in different thicknesses. Fifty (N=50) standardized single crowns preparations were made in fiberglass-reinforced epoxy resin (NEMA grade G10), digitalized, and restorations were machined in CAD-CAM, composing 5 groups (n= 10): Control: 1.5 mm (milled zirconia framework + manual layered porcelain); Yz monolithic 1.5 mm; Yz monolithic 1.0 mm; CAD-on 1.5 mm; and CAD-on 1.0 mm (milled zirconia framework 0.5 mm thickness bonded by a low fuse ceramic to a milled lithium disilicate layer of 1.0 mm or 0.5 mm, respectively). The G10 bases were conditioned with 10% hydrofluoric acid; the crowns were air abraded with 110 μm alumina particles; and then luted onto each other with self-adhesive resin cement. A cyclic fatigue test was performed (initial load: 400N for 10,000 cycles, frequency of 20 Hz, step size of 200N) until failure, and the data was submitted to a survival statistical analysis. No failures were observed at Yz monolithic 1.5 mm. High and similar performance was observed for Cad-On groups and Yz monolithic 1.0 mm. The control group depicted the worst behavior. The Weibull modulus of CAD-on 1.5 mm was higher than the control while being similar to the other conditions. Both the monolithic systems and the CAD-on technique showed high and similar fatigue fracture behavior and survival rates, which were also higher than the control bilayer system. Both systems reduced the occurrence of delamination failures, making them suitable for clinical use.

Abstract An aortoesophageal fistula is an abnormal communication between the aorta and the esophagus, causing potentially fatal upper gastrointestinal bleeding. The objective of this article is to report a successful case of treatment with a single aortic endovascular approach and conservative treatment of the esophagus in a case of aortoesophageal fistula. An 81-year-old patient was admitted with signs of massive upper gastrointestinal bleeding and, after tests, an aortoesophageal fistula was diagnosed. Endovascular treatment was chosen and performed successfully. The patient was discharged after 9 days in hospital and remained in outpatient follow-up until the condition completely resolved. Early diagnosis is extremely important, since this is a fatal condition if left untreated. It is hoped that this report contributes content of relevance to the scientific community.

Abstract The objective of the study was to measure the impacts of Pronaf access on family farming (FF) performance measures with analysis for the FF and its typologies Pronaf B and Pronaf V of the 2017 Agricultural Census. Variables related to family farmers, their establishments and climate were used. The methodology was composed of Entropy Balancing for treatment analysis and Minimal Weighted Squares to measure the impacts. The use of different levels of intensity confirmed the presence of regional concentrations in access in all analyzes. The results of the impacts on FF showed to be related to the Pronaf V typology, confirming the need to analyze the disaggregated FF. The impacts on the Pronaf B typology were negative, suggesting that these farmers are potentially using the obtained credit inappropriately and/or inefficiently. This reaffirms the need to integrate Pronaf with other policies, such as technical assistance and rural extension.

ABSTRACT Objective: To understand the meanings attributed to family relationships by women who have experienced domestic violence. Method: Explanatory study using Symbolic Interactionism and Grounded Theory as references. Data were collected from March to November 2021, through online interviews with 23 women found on the social media application Facebook®. Results: Data analysis allowed the construction of a theoretical model consisting of three processes: “We learned that it was normal to be mistreated”: experiencing a context of violence in the family of origin; “I just wanted a family”: experiencing partner violence and redefining family relationships in the context of violence. Conclusion: The meanings attributed to family relationships are elaborated and modified according to the interpretation, trajectory of confrontation, and interactions of women with other individuals and objects in the social web, over time. When experiencing domestic violence, women give new meaning to their feelings and begin to attribute new values, emotions, and empathy to family relationships, expanding their understanding of their weaknesses and potential.
