Published: January 2021

Attending to a stimulus enhances the neuronal responses to it, while responses to nonattended stimuli are not enhanced and may even be suppressed. Although the neural mechanisms of response enhancement for attended stimuli have been intensely studied, the neural mechanisms underlying attentional suppression remain largely unknown. It is uncertain whether attention acts to suppress the processing in sensory cortical areas that would otherwise process the nonattended stimulus or the subcortical input to these cortical areas. Moreover, the neurochemical mechanisms inducing a reduction or suppression of neuronal responses to nonattended stimuli are as yet unknown. Here, we investigated how attention directed toward visual processing cross-modally acts to suppress vestibular responses in the human brain. By using functional magnetic resonance spectroscopy in a group of female and male subjects, we find that attention to visual motion downregulates in a load-dependent manner the concentration of excitatory neurotransmitter (glutamate and its precursor glutamine, referred to together as Glx) within the parietoinsular vestibular cortex (PIVC), a core cortical area of the vestibular system, while leaving the concentration of inhibitory neurotransmitter (GABA) in PIVC unchanged. This makes PIVC less responsive to excitatory thalamic vestibular input, as corroborated by functional magnetic resonance imaging. Together, our results suggest that attention acts to suppress the processing of nonattended sensory cues cortically by neurochemically rendering the core cortical area of the nonattended sensory modality less responsive to excitatory thalamic input.

SIGNIFICANCE STATEMENTHere, we address a fundamental problem that has eluded attention research for decades, namely, how the brain ignores irrelevant stimuli. To date, three classes of solutions to this problem have been proposed: (1) enhancement of GABAergic interneuron activity in cortex, (2) downregulation of glutamatergic cell activity in cortex; and (3) downregulation of neural activity in thalamic projection areas, which would then provide the cortex with less input. Here, we use magnetic resonance spectroscopy in humans and find support for the second hypothesis, implying that attention to one sensory modality involves the suppression of irrelevant stimuli of another sensory modality by downregulating glutamate in the cortex.
Proximity and Expectancy Modulate Response Vigor After Reward Omission
Authors: Chen Zhang , Reimer Christina B. , Verbruggen Frederick
Published: January 2021

Both humans and some non-human animals tend to respond more vigorously after failing to obtain rewards. Such response invigoration becomes more pronounced when individuals have increased expectations of obtaining rewards during reward pursuit (expectancy), and when they perceive the eventual loss to be proximal to reward receipt (proximity). However, it was unclear whether proximity and expectancy may have distinct influences on response vigor. To investigate this question, we developed a computerized ’scratch card’ task, in which participants turned three cards one by one and won points when all three cards matched (AAA). After each game, they pressed keys to confirm the outcome and start a new game. We included three types of losses: AAB, where participants had increased expectancy of winning as the game evolved, and the final outcome was proximal to winning; ABB and ABA, with reduced expectancy, but high proximity to winning; and ABC, with reduced expectancy and low proximity to winning. In three online studies, we consistently observed that participants confirmed losses more quickly than wins. Importantly, detailed analyses of the different types of losses revealed that proximity reduced vigor, whereas expectancy increased it. Together, these findings are in line with general appraisal theories: the adjustments of response vigor may be triggered by the appraised discrepancy between the current state and a reference state (e.g., attaining one’s goal), and serve to close the gap and facilitate goal pursuit. These findings may also have implications for the effect of ‘near miss’ on gambling persistence. Further exploring how reward omission impacts response vigor may help us better understand the goal pursuit process, and how it becomes maladaptive under certain circumstances.

N6‐methyladenosine (m6A) regulates a variety of physiological processes through modulation of RNA metabolism. This modification is particularly enriched in the nervous system of several species, and its dysregulation has been associated with neurodevelopmental defects and neural dysfunctions. In Drosophila, loss of m6A alters fly behavior, albeit the underlying molecular mechanism and the role of m6A during nervous system development have remained elusive. Here we find that impairment of the m6A pathway leads to axonal overgrowth and misguidance at larval neuromuscular junctions as well as in the adult mushroom bodies. We identify Ythdf as the main m6A reader in the nervous system, being required to limit axonal growth. Mechanistically, we show that the m6A reader Ythdf directly interacts with Fmr1, the fly homolog of Fragile X mental retardation RNA binding protein (FMRP), to inhibit the translation of key transcripts involved in axonal growth regulation. Altogether, this study demonstrates that the m6A pathway controls development of the nervous system and modulates Fmr1 target transcript selection.
Housing habitability in times of COVID-19 in Mexico. Case of Culiacan
Authors:   Universidad Autónoma de Sinaloa, Verdugo López Mercedes
Published: January 2021

The prolonged social distancing caused by the Covid-19 pandemic represents an unprecedented condition that has severely impacted on the different aspects of public and private life in Mexico. One of the most affected areas is the role of housing and its habitability. In a very short time, homes have become a place of work, a school, and sometimes a medical care facility. This article exposes the importance of the inhabitant's bond with their home and the habitability that is reconfigured in the social conditions imposed by the current health crisis. We believe that preventive isolation can contribute to containing contagions if the living conditions encourage to the collaboration of citizens. The methodology consists of a case study carried out in Culiacán, one of the Mexican cities most affected by the pandemic. The analysis is derived from the statistical processing of an online survey, applied in two times to the target population. In the first, 231 questionnaires were processed as a filter and in the second 50, which contained the most significant topics on the subject.
The Potential of Modeling Process for Social Sciences and Social Work
Authors:   Universitat de Barcelona, GRITS (Grup de Recerca i Innovació en Treball Social). Barcelona. España., Lorenzo-Aparicio Andrés
Published: January 2021

Simplification and necessary reductionism in a model cannot lead to detailed descriptions of social phenomena with all their complexity, but we can obtain useful knowledge from their application both in specific and generic contexts. Human ecosystems, that perform as adaptative complex systems, have features which make it difficult to generate valid models. Amongst them, the emergency phenomena, that presents new characteristics that cannot be explained by the components of the system itself. But without this knowledge derived from modelling, we, as social workers, cannot suggest answers that ignore the structural causes of social problems. Faced with this challenge we propose Agent Based Modelling, as it allows us to study the social processes of human ecosystems and in turn demonstrates new challenges of knowledge and competences that social workers might have.

Formulae, Wordplay, Verses and More: Where Humor Research Meets Phraseology
Authors: Masiulionytė Virginija
Published: January 2021

This paper aims to examine the meeting points between phraseology and humor research, focusing on the role and the functions of fixed phrases in humor discourse. The examples to illustrate certain aspects of usage of fixed phrases for joke purposes are taken mainly from social media such as Facebook and Twitter and include jokes in English, German, Lithuanian, Russian, and Polish. In the course of the investigation, a distinction ought to be made between set phrases (idioms in the narrower sense of the term, proverbs, catch phrases etc.) and fixed phrases in general. Set phrases (phrasemes) have an “added value” regarding their meaning – be it a figurative element, be it ready-made reasoning or behavioral models in short form in the case of adages. In humor discourse idioms – and proverbs – are used mainly for wordplay, in which both the literal and the idiomatic meaning are activated. The wordplay can happen also in verse form. Adages can be transformed or twisted resulting in new parodistic or funny sayings. Fixed phrases outside of the phraseology can be separated into two groups: phrases typical for a particular discourse type and joke frame related phrases. The former, as means to evoke a certain frame, are used in parodistic jokes (e.g., the phrase ladies if he evokes the dating tips frame). The latter constitute a distinct class of fixed phrases which can be found only in the humor discourse: these phrases act as joke formulae und provide a basis for bigger or smaller joke categories. Certain phrases in this group, such as checks notes or nothing like deserve a mention as irony markers with a distinctive evaluative character. The shared feature of all these idiomatic and non-idiomatic phrases is that they are well-known, re-occur in the language and, in that respect, can considered belonging to the sphere of interests of phraseology. Regarding the main functions of fixed phrases in the humor discourse, they can contribute to the social play, provide the cues to switch to a nonserious humor mindset or express evaluation – from mild mockery to aggressive ridicule.
Collocations in Letters to the Editor of Die Zeit
Authors: Skog-Södersved Mariann , Malmqvist Anita
Published: January 2021

In the field of phraseology collocations have been less extensively researched than idioms. Because of their lower degree of idiomaticity collocations do not normally cause receptive problems in foreign language learning but need to be paid attention to when producing texts. We therefore argue that collocations are an important part of phraseology.The purpose of this paper is to investigate the syntactic structure, use and functions of collocations in 243 Letters to the Editor published in the German weekly newspaper Die Zeit. After consulting two dictionaries of collocations and some more universal sources a total of 278 collocations were identified and their respective bases and collocates were determined. The results show that nouns make up the majority of the bases (97%), while adjectives and verbs prevail among the collocates (96%). This is contradictory to the distribution of parts of speech in one of the two most comprehensive German dictionaries of collocations. A closer analysis of the empirical material reveals that the bases seem to reflect the subjects discussed in the letters, whereas the collocates provide the means for expressing the authors’ attitudes and values.

Authors: Shi Tong Xin , Li You
Published: January 2021

Milk protein is beneficial for the health of infants and is mainly derived from bovine, sheep, goat or camel milk. High Fischer ratio peptides usually comprise two to nine amino acid residues. The ratio is computed as a molar ratio between branched-chain amino acids (BCAAs) over aromatic amino acids (AAAs) with various claimed health-promoting functions. In this Lilliput review, the classification and nutritional functions of milk proteins are discussed, the physiological functions and preparation methods of high Fischer ratio peptides are introduced, and the application of oligopeptide with unique amino acid composition and physiological functions in infant formula milk powder are reviewed. The development status of relevant industry is also summarized with future prospects. It is concluded that application of high Fischer ratio peptides prepared from milk protein in infant formula food is of great significance and requires further studies.

Published: January 2021

O objetivo desta pesquisa foi de verificar a influência da propriedade, gestão e controle familiar na prática de gerenciamento de resultados das empresas brasileiras listadas na B3. Adotou-se uma abordagem quantitativa, utilizando-se do modelo de Kang e Sivaramakrishnan (1995) para mensurar os accruals discricionários, realizando-se a análise a partir de testes de estatística descritiva, correlação e regressão linear múltipla. Os dados foram obtidos da Economática©, somando o total de 207 empresas, das quais 80 eram de propriedade familiar, enquanto 77 obtinham a gestão familiar e 55 o controle familiar, abrangendo um período de seis anos. Os resultados da pesquisa permitiram observar que as empresas de propriedade, gestão e controle familiar apresentam menores níveis de gerenciamento de resultados do que as empresas não familiares, sendo esta diferença estatisticamente significante. A segregação das empresas familiares em propriedade, gestão e controle familiar, permitiu verificar que somente as companhias cujo controle é familiar tem relação negativa com os níveis de gerenciamento de resultados. O custo de agência é reduzido pela presença do controle familiar, levando a menores índices de gerenciamento e melhor qualidade dos lucros. Essas entidades evitam ações que prejudicam o valor futuro devido à preocupação na sustentabilidade transgeracional.

A METHOD FOR QUALITATIVELY MAPPING THE FLOOD PHYSICAL VULNERABILITY OF RESIDENTIAL AREAS
Authors: Doan To-Uyen Thi , Kanno Ariyo , Yamamoto Koichi , Imai Tsuyoshi , Higuchi Takaya , Sekine Masahiko
Published: January 2021

Mapping flood physical vulnerability is spatially limited because it requires input data such as building structures and materials, which are unavailable on large spatial scales. In this study, we propose a new method for qualitatively evaluating the flood vulnerability of residential areas in the context of the exposure and resilience to flood hazard on large spatial scales. This method utilizes the possible correlations between the structural physical vulnerability and residential types obtained from the statistical classifications of multispectral satellite images. Because multispectral classification is well-established as an inexpensive technique for automatically classifying land cover types over wide areas, our method is feasible and efficient for mapping the physical vulnerability of residential areas. As a case study, we present an application of the proposed approach to the Thach Ha district, Ha Tinh province, Vietnam, using the Japanese type 2 Advanced Visible and Near Infrared Radiometer (AVNIR-2) images and Phased Array type L-band Synthetic Aperture Radar (PALSAR) images captured by the Advanced Earth Observing Satellite (ADEOS).
EVALUATION OF THE CHARACTERISTICS OF PLASTIC EXPLOSIVE ADHERED BY LIQUID NATURAL RUBBER
Authors: Doan Khai Minh
Published: January 2021

Plastic explosive (PBX) is an explosive that a polymer binder is used to reduce the sensitivity of high explosives for various applications. This paper presents the characteristics of the PBXs based on liquid natural rubber (LNR) and hexogen (RDX). The PBXs are prepared according to a modified formulation of the Composition C-4. The plasticity of the PBXs is determined according to the MIL-STD-650 method 211.1. The uniaxial compression of the PBXs examined by the STANAG 4443. The test of the sensitivity of PBXs to friction is carried out by STANAG 4487. The thermal stability is tested by the STANAG 4556 at 100 oC for 40 hours. The results indicated that the plasticity is found to be more than 0.018 in accordance with the MIL-C-45010A. Further, the modulus of elasticity, yield strength, and strain can be adjusted by the composition of the LNR binder. In addition, the frictional sensitivity of the PBXs is significantly reduced to more 360 N of the load. The thermal stability is in the range of 0.156 to 0.225 ml.g-1 and completely meets technical requirements. Therefore, the direction of using LNR as a binder for PBXs gives acceptable results for further researches.

Authors: Le Tuan Van
Published: January 2021

This work presents batch mode experiments of combination ultrasonic wave (USW) and H2O2 in pre-treatment of landfill leachate. Additionally, in continuous mode experiments, a modified aerated bio-filter (ABF) was designed for the treatment of synthetic wastewater and the leachate (after treatment by USW/H2O2), with the stepwise increasing the volume ratios between the leachate and synthetic wastewater up to 100% of the leachate. The leachate was collected from Thuy Phuong landfill in Thua Thien Hue province, Vietnam, with characterized of color: 14,213 ± 150 PCU (n=3), N-NH4: 1213 ± 148 mg/L (n = 3), COD: 6068 ± 1611 mg/L (n = 3), BOD5: 1211 ± 158 mg/L (n=3), BOD5/COD: ~0.21 and pH ~7.7. The USW/H2O2 had shown a great potential to remove COD, N-NH4 and color of the raw leachate in short treatment time (5 mins). The ABF system was well operated with organic loads (0.26 to 1.13 kg-COD/m3/d), with a very small sludge volume was formed. Moreover, the presence H2O2 can be used for decreasing odor of the leachate. As “green” advanced oxidation process (AOPs), the combination of USW/H2O2 could be used to improve the effectiveness of activated sludge process in treatment of refractory compounds from landfill leachate.
WATER QUALITY ASSESSMENT OF SAIGON RIVER FOR PUBLIC WATER SUPPLY BASED ON WATER QUALITY INDEX
Authors: To Thuy Chau
Published: January 2021

Water Quality Index (WQI) is a dimensional number that aggregates information from many water quality parameters according to a defined method. WQI is accepted as an efficient tool for water quality management. In this study, WQI of Saigon river for public water supply was calculated from nine water quality parameters including pH, suspended solids (SS), dissolved oxygen (DO), chemical oxygen demand (COD), nitrite, ammonia, phosphate, total dissolved iron and total coliform based on water quality data obtained monthly from January 2016 to December 2019 at three sampling sites. The results showed that most of WQI values belonged to class III (medium water quality with the WQIs of 35 – 64) and class IV (poor water quality with the WQIs of 11 – 34) and a deteriorating trend was observed from upstream to downstream of Saigon river. The river water quality could not be used for public water supply.

Published: January 2021

The incredible growth of plastic waste is a major concern for the whole society in recent years. The accumulation of plastic waste has badly effects on wildlife, habitat, and humans. Plastics that act as pollutants are categorized into different sizes, from micro to macro. Disposable plastic waste was collected at the bakery shop and removed the residue food by tap water and NaOH 1M to remove residual food. This study focuses on modify waste plastic by sulfuric acid to bind the sulfonated function group on the structure of the polystyrene chain at room temperature. The sulfonated product was used for removing heavy metal ion in water with the mechanism of the ion exchange process. The prepared ion exchange material was characterized by FTIR and SEM to ensure that the sulfonation process has happened. The chromium (III) ion removal by modified ion exchange product in continuous mode was affected by an operational parameter such as the bed height of sulfonated material. The Yoon-Nelson and Thomas model were used to analyze the experimental result and the model parameters were evaluated. From this result, it can be concluded that with the increasing amount of sulfonated waste polystyrene, exchange capacity, and the time required for a 50% adsorbate breakthrough was higher.

High photocatalytic activity of magnetic composite photocatalyst NiFe2O4/BiVO4 for rhodamine b degradation under visible led light irradiation
Authors: Doan Minh Que , Nong Linh Xuan , Nguyen Trinh Duy
Published: January 2021

To improve the photocatalytic activity of BiVO4 semiconductor, the design of composite photocatalyst containing BiVO4 with surpassing the recombination of photoinduced electron and hole is highly required. In this study, magnetic composite photocatalyst with NiFe2O4 and BiVO4 has developed through two-steps hydrothermal method. The results show that the morphology of the bare BiVO4 had a decahedral shape with smooth surfaces along with particles, while the morphology of the bare NiFeO4 had nanoparticles with the diameter in a range of 10-20 nm. In the case of 20% NiFe2O4/ BiVO4 samples, a large of nanoparticles were deposited into large bulk, implying the incorporation of NiFe2O4 nanoparticles on the surface of BiVO4 catalyst. Compared with the bare BiVO4, the NiFe2O4/BiVO4 composites had a higher photocatalytic efficiency for photodecomposition of rhodamine B (RhB) under visible LED light irradiation. The improvement of photocatalytic degradation RhB activity should be attributed to a direct Z‐scheme system. Therefore, the fabrication of semiconductors with a combination of magnetic materials provides new insight for the enhancement of their photocatalytic performance.

Authors: Duong Hung Cong , Tran Lan Thi Thu
Published: January 2021

Membrane distillation (MD) has great potential for the treatment of hyper saline waters, including liquid desiccant solutions used in air-conditioning systems. Previous experimental investigations have demonstrated the technical feasibility of MD for regeneration of liquid desiccant solutions. In this study, a direct contact membrane distillation (DCMD) process of the LiCl liquid desiccant solution was simulated using MATLAB software. The simulation was first validated using data obtained from experimental tests. Then, it was used to elucidate the water temperatures, LiCl concentration, and water flux profiles along the membrane leaf inside the DCMD membrane module. Finally, with the help of the simulation, the effects of membrane properties and process operating conditions on the DCMD process performance were systematically examined. The results obtained from this simulation enrich the knowledge and hence facilitate the realization of MD for the liquid desiccant solution regeneration application.

Published: January 2021

Recent interest in wastewater treatment has shifted to the use of agricultural waste to treat antibiotics in aqueous solutions due the economic efficiency the technique brings. This study focuses on the synthesis, properties and study of the kinetic mechanism of activated carbon and its potential application to remove antibiotics from aqueous solutions. Activated carbon is synthesized from sugarcane bagasse by activated method with active substance of ZnCl2. With a specific surface area of about 980.84 m2/g and high porosity, the product could absorb a large amount of ciprofloxacin (CIP) antibiotics. The properties of materials are characterized by relevant analytical techniques such as scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Brunauer-Emmett-Teller (BET). The behavior of CIP adsorption was studied under the effect of adsorption dose, initial CIP concentration and pH value. The adsorption and isothermal mechanisms are also studied. The results show that the adsorption adhered to the second kinetic model and the experimental data was found to be reasonably fitted to the Langmuir isotherm. Therefore, activated carbon manufactured from sugarcane bagasse could be used as a potential adsorbent to effectively remove antibiotics from aqueous solution.
Rationality or reasonableness: an attempt at changing the paradigm of philosophical cognition of God – thought of Xavier Zubiri
Authors: Niziński Rafał S.
Published: January 2021

The majority of the philosophical proves of the existence of God or other philosophical attempts of talking about Him try to meet standards of rationality only. In this way they reach mostly a philosophical notion of God which rules out a religious relationship to Him. Zubiri is trying to present a philosophical way which leads to a notion of God, who can be at the same time a God of philosophy and of religion. But this means overcoming rationality with reasonableness. Reasonable means compatible with human life.

Published: January 2021

El objetivo de este artículo es analizar la lectura literaria escolar, específicamente, el reconocimiento y la participación como categorías epistémicas y políticas que operan en los encuentros lectoliterarios en la escuela, desarrollando dos perspectivas de revisión: la experiencia lectora y la distinción de dos caminos explicativos sobre el conocimiento; uno que lo sitúa como revelación de la realidad, y otro que lo concibe como construcción de mundo en la experiencia. Metodológicamente, este trabajo corresponde a una revisión teórica que busca articular las dimensiones epistémicas, políticas y didácticas de las configuraciones posibles del reconocimiento y la participación imbricadas en distintas concepciones de la educación literaria. Para ello, desde una mirada interpretativa, se realiza una aproximación conceptual a la díada conocimiento/realidad, luego se describen aspectos de la experiencia lectora y, finalmente, se desarrolla un enfoque crítico sobre la lectura literaria en la escuela, situando la reflexión en el campo de la justicia educativa como condición para la justicia social. Entre las principales conclusiones destacan: la necesidad de complejizar el reconocimiento epistémico y político del lector literario escolar para habilitar su participación expresiva y la necesidad de situar la reflexión didáctica de la educación literaria más allá de lo metodológico

Abstract The stem rot and fusarium vascular wilt are among the main factors the most limiting the passion fruit cultivation in the State of Mato Grosso. This study aimed to evaluate the resistance / susceptibility of the genus Passiflora species to soil pathogens from different biomes of Mato Grosso (Cerrado, Pantanal and Amazon). The part I evaluated the response of P. edulis Sims, P. foetida, P. nitida and P. quadrangularis on eight isolates of F. solani. In part II was evaluated the genotypes P. edulis Sims, P. mucronata, P. foetida, P. nitida and P. morifolia on three isolates of F. oxysporum f. sp. passiflorae. The experimental design was randomized blocks in factorial arrangement (genotypes x isolates). The statistical analysis used for both steps were the variance analyses by F test and grouping of averages of genotypes by Scott-Knott test (P =0.05). Among the isolates of F. solani was found that isolates FS8A and FS3P are more aggressive, indicating genetic variability among isolates. The most resistant genotypes to the pathogen were P. nitidaand P. foetida. Among the isolates of F. oxysporum f. sp. passiflorae there was no significant difference in aggressive levels, and the P. mucronata and P. nitida species are more resistant to Fusarium. Thus genotypes P. nitida, foetida and P. mucronatacan be indicated as a resistance source to improvement of commercial passionfruit programs.

Published: January 2021

ABSTRACT Spectral remote sensing and proximal sensors are important tools for managing the plant-pathogen relationship. The lack of experimental planning and the probability of error in agricultural studies may result in work repetition and, consequently, in financial expenses and costs with human resources. To reduce such problems, determining the optimum size of the experimental plot for treatments is one of the adopted methods. The objective of this study was to estimate the optimum plot size for reflectance in soybeans that were treated with different fungicide levels according to the methods of modified maximum curvature and maximum distance. Reflectance readings were carried out for the soybean crop with a radiometer GreenSeeker®, considering basic units of 0.45 m² in an area of ten rows, 10 m long, for each treatment. Treatments were applied to create a gradient of Asian soybean rust, varying the number of fungicide applications. Data were collected in two phenological stages (R5.5 and R6), obtaining 300 simulations of experimental area for each stage. Based on the results, the use of 5.40 m² plots with a group of three rows, 4 m long, is recommended.

RESUMO As Parcerias Público-Privadas (PPPs) surgem como instrumentos da administração pública brasileira, no contexto das políticas de desestatização, iniciadas em 1995 pelo Plano Diretor da Reforma do Estado. Essa reforma e a busca por maior governança se basearam na experiência do New Public Management, trazendo consigo os princípios do gerencialismo e do governo por contratos (GAUDIN, 2007). O objetivo deste trabalho é analisar os instrumentos de participação social presentes na legislação das parcerias público-privadas de São Paulo e Minas Gerais (2005-2015), sob a perspectiva deliberativa da democracia. Através do método da análise bibliográfica e documental, observamos o escopo e a obrigatoriedade da participação social, identificando os instrumentos consulta pública, audiência pública e composição dos conselhos gestores. Concluímos que a consulta pública é o único instrumento de participação efetivamente obrigatório nas PPPs. Nos conselhos gestores de parcerias, observa-se a participação de representantes do Estado e/ou participantes com perfil técnico, marcada pela ausência de representantes da sociedade civil. Trata-se de uma composição e de uma adoção de instrumentos que enfraquece o caráter deliberativo da democracia. Por fim, levantamos diversos casos de parcerias que apresentam problemas legais, financeiros e contratuais, com intuito de sugerirmos uma agenda de pesquisa.

Resumo Introdução Com o início da pandemia, inquietações quanto à condução da parada cardiorrespiratória em casos suspeitos e confirmados da COVID-19 surgiram ante as peculiaridades e publicações científicas quanto à temática. Dessa forma, o presente estudo apresenta uma reflexão e demonstra as novas recomendações acerca dos cuidados necessários a serem adotados pela equipe multiprofissional. Método Trata-se de um estudo de reflexão teórica, de caráter descritivo e abordagem qualitativa com base em documentos convencionais e não convencionais emitidos pelos principais órgãos reguladores e revistas de grande impacto que abordam as temáticas discorridas. Além disso, não houve recorte temporal para a seleção do referencial bibliográfico. Resultados Os resultados expostos abordaram o cuidado relacionado com os recursos humanos e materiais envolvendo a temática, o manejo da via aérea nesse evento em pacientes que estavam ou não em uso de intubação endotraqueal, assim como em relação aos indivíduos em posição prona. Conclusão e implicações para a prática Diante das discussões apresentadas, é evidente a necessidade de atualização por parte das instituições de saúde em suas rotinas e dos profissionais que se encontram neste estudo como mecanismo de proteção e manutenção da qualidade do cuidado prestado.

ABSTRACT Purpose: The speech therapy practice in mental health is questioned by the challenge of producing shared care strategies to, above all, expand the conditions and the communicational repertoire, the discursive and social circulation of people with mental suffering. Objective of this study was to identify the perception of clinical listening in professionals of Child and Adolescent Psychosocial Care Center (CAPSij), specifying the role of speech therapy in the care and listening of patientes. Methods: This is a participatory and dialogical research. A discussion group was used to collect data. Results: were grouped in the following categories: listening conception; listening and working process; listening effects; speech therapy and clinical listening. These professionals think of clinical listening as a central device for mental health care. The clinical listening favors reflection on the bio psychic dynamics of healthcare. It was observed contributions of speech therapy in intra and interinstitutional scopes, in the clinical-therapeutic work of the health professionals, patients and relatives. The speech therapist’s skills and knowledge about organic aspects of child development in the opinion of professionals enhance clinical listening. Conclusion: It was concluded that without teamwork, care in CAPSij would not happen in a qualified way under the public health policies: Psychosocial Care Network (PSCN) and Unified Health System (SUS) frameworks. The clinical listening is a condition of possibility of the care offered by the professionals.

ABSTRACT Purpose: to evaluate the lingual frenulum and breastfeeding in infants from a maternal-perinatal referral center, as well as to monitor infants with ankyloglossia up to six months of age. Methods: a cohort study conducted at the Instituto Nacional Materno Perinatal - Maternidad de Lima in Lima, Peru. The consecutive intentional sample consisted of 304 newborns and their respective mothers, evaluated during December 2017 and January 2018, which were the baseline of the study. A clinical evaluation of the lingual frenulum adapted and the Clinical Evaluation of Breastfeeding Efficacy (CEBE) scale, was performed. Results: of the 304 newborns, 15 (4.9%) were considered with altered frenulum, and only 4 (26.7%) presented a low score in CEBE. The mean of the CEBE score was 9.3. (DP=1.35, Min=3, Max=10). Of the follow-up infants, only 2 (13.3%) persisted with breastfeeding difficulties for which frenotomy was indicated. Conclusion: This study demonstrates the low prevalence of ankyloglossia in infants, as it does not indicate a trend of difficulty or negative interference in breastfeeding.

As is well known, nano-particles have received particular attention in various application fields for fabricating materials with novel functionalities. This paper presents the effect of nano-silica on the properties of magnesium oxychloride cement (MOC), such as setting time, the hydration process, compressive strength, composition and microstructure of the paste. Results show that nano-silica can promote the hydration process and shorten the initial and final setting times of MOC, which were shortened by 14% and 8% when 5% nano-silica was incorporated in the MOC. In addition, nano-silica can increase the compressive strengths and make the pore structure of MOC denser. The compressive strengths at 3 days and 28 days increase by 29.5% and 18.0%, respectively, when 5% nano-silica is incorporated in MOC. Compared with the pure MOC paste, nano-silica yields no new hydration products in MOC besides P5 and magnesium hydroxide (Mg(OH)2). The higher compressive strength is mainly attributed to the water absorption and filling effect of nano-silica in MOC slurry.
