« Resident and Visitor », Brook Andrew et Christine Barthe en conversation
Authors: Barthe Christine
Published: April 2022

En introduction à une conversation avec l’artiste Brook Andrew, l’auteur rappelle les enjeux du programme de résidence mené par le musée du quai Branly depuis 2008. Ce programme, visant à soutenir des projets et à intégrer de nouvelles pièces à la collection photographique du musée, a donné lieu à diverses œuvres, dont certaines, comme celle de Brook Andrew, ont été élaborées en liaison avec la collection de photographies historiques de l’établissement. La conversation permet de mieux appréhender l’œuvre de Brook Andrew dans son ensemble. Elle contextualise la démarche qui l’a conduit en 2016 à explorer la question de l’accès aux collections photographiques et à développer le rôle de l’artiste comme passeur.

Authors: Spanholi Maira Luiza , Mendes Francisco Eduardo , Costa Lucas de Almeida Nogueira da , Fares Lucas Rolo , Young Carlos Eduardo Frickmann
Published: April 2022

Os Parques Nacionais são áreas criadas para proteger a biodiversidade e promover o desenvolvimento sustentável. O objetivo deste trabalho é demonstrar a importância do Parque Nacional da Chapada dos Guimarães (PNCG) em evitar o desmatamento e proporcionar benefícios econômicos e ambientais na região em que está inserido. Para isso, utilizando diferentes metodologias de valoração econômica ambiental, foi calculada a redução das emissões de gases de efeito estufa e da erosão do solo pelo desmatamento evitado, assim como a influência do parque sobre os usos da água superficial, do ICMS ecológico e do uso público. Estimou-se que o PNCG evitou cerca de 10 mil hectares de desmatamento, impedindo a erosão de 195 mil toneladas anuais de solo e a emissão total de 1,5 milhões de tCO2e. O PNCG influencia até 45,2% do consumo de água da bacia do Rio Cuiabá, com valor de influência sobre os consumos da água estimado em até R$ 73,9 milhões. Em 2019, foram repassados para Cuiabá e Chapada dos Guimarães R$ 937 mil como ICMS ecológico devido a existência do PNCG. Estimou-se ainda, que a visitação ao PNCG induziu R$ 60,1 milhões anuais de produção de bens e serviços locais através do efeito multiplicador dos gastos que foram realizados pelos visitantes no ano de 2019. Portanto, áreas protegidas, tais como o PNCG, são capazes de evitar o desmatamento e assoreamento dos rios, auxiliar na mitigação das mudanças climáticas pela sua capacidade de estocar dióxido de carbono, além de servirem como indutoras do desenvolvimento econômico da região em que estão inseridas.

Authors: Coy Martin , Huber Christoph
Published: April 2022

Além de considerações conceituais introdutórias, este artigo trata de um dos “grandes” tópicos de pesquisa da Ecologia Política, que é a destruição das florestas e savanas tropicais. Com base em muitos anos de pesquisa empírica no Norte de Mato Grosso (Brasil), investigamos as mudanças das relações homem-meio ambiente. Abordamos, particularmente, as configurações locais de integração nas redes de produção globais de soja e nas implicações socioecológicas a elas associadas. Usa-se como estudo de caso a “cidade do agronegócio”, Sinop, e seus arredores.

Neste artigo analisamos a evolução recente (2006-2017) e as projeções (2019-2029) dos principais produtos da agropecuária brasileira. O objetivo é avaliar as dinâmicas regionais da agropecuária, sua importância para a economia, para o mercado interno e para a balança comercial. Ao mesmo tempo, apontamos as contradições e as fragilidades do “Brasil potência agrícola” construído com base em um projeto de reprimarização da economia, que constitui um obstáculo ao desenvolvimento do país e que intensifica cada vez mais a exploração dos recursos naturais.
O Programa de Regionalização do Turismo no Brasil e a competitividade espacial
Authors: Fonseca Maria Aparecida Pontes da , Todesco Carolina , Silva Rodrigo Cardoso da
Published: April 2022

O Programa de Regionalização do Turismo (PRT) completa 16 anos de implementação e nesse período tem apresentado mudanças significativas com o aumento da quantidade de regiões turísticas, concomitantemente à diminuição do número de municípios que integram as referidas regiões. O objetivo do presente trabalho é analisar as diretrizes norteadoras do processo de regionalização turística implementado pelo Ministério do Turismo no Brasil. A metodologia da pesquisa está fundamentada em um estudo bibliográfico e documental, tendo como principal fonte as portarias ministeriais e as edições do Mapa do Turismo Brasileiro. Os resultados indicam que a fragilidade dos critérios para a composição das regiões turísticas e da categorização dos municípios se constituem em um entrave para maior êxito dessa política pública. A diretriz norteadora do PRT é a competitividade que vem induzindo a seletividade espacial no âmbito do programa através da categorização dos municípios e da proliferação de regiões turísticas em busca de maior identidade ao produto turístico ofertado. Desse modo, o PRT estimula tanto a competitividade inter-regional como a competição intrarregional.
Riscos hidrometeorológicos híbridos na bacia do Alto Iguaçu – Paraná (Brasil)
Authors: Goudard Gabriela , Mendonça Francisco de Assis
Published: April 2022

A compreensão dos riscos ligados ao clima reveste-se de grande complexidade, sendo necessário o entendimento das condições de perigo, suscetibilidade e vulnerabilidade de maneira conjugada. Neste contexto, o presente artigo coloca em evidência uma análise dos riscos híbridos relacionados aos episódios pluviais extremos (inundações, enchentes e alagamentos) na bacia do Alto Iguaçu. Para tanto, são utilizados dados de áreas de inundação, suscetibilidade e vulnerabilidade, sendo estes analisados de maneira integrada. Os principais resultados destacam os seguintes pontos: I) o risco híbrido é resultado de uma conjunção de fatores sociais, naturais e tecnológicos do ambiente; II) os riscos hidrometeorológicos híbridos são diferenciados ao longo da bacia, verificando-se sobreposições entre áreas de alta a muito alta vulnerabilidade e as porções mais afetadas pelos episódios pluviais extremos e; III) a proposta de análise dos riscos de forma híbrida configura-se como uma tentativa de análise sistêmica e holística, visando a gestão de riscos.
Análise da atividade neoextrativista da mineração de ouro no estado do Amapá (2000-2020)
Authors: Fernandes Rhuan Muniz Sartore , Dhenin Miguel Patrice Philippe
Published: April 2022

On the one hand, the withdrawal of natural resources from the subsoil has been defended as an important generator of foreign exchange and as a mechanism for economic growth. On the other hand, those responsible (environmentalists and / or affected groups) highlight their environmental and social impacts, their inability to promote local development and to generate benefits for localities and those responsible. Based on these considerations, the objective of the paper is an analysis of the impacts of the neo-extractive mining activity in the state of Amapá, particularly the extraction of gold. Therefore, the pertinent bibliography of the area is read, with the support of a database (RAISG, SIGMINE-ANM, among others). To illustrate this situation, we can base our analysis on several projects that already exist in Amapá, either in the legal sphere (mining companies) or by illegal mining (artisanal and small scale mining), as we can see in the maps generated. They highlight what already exists in legal mining (authoritative titles) and expectations (about the right to mine, which are represented by the requirements). Thus, it is observed that the socioenvironmental impacts arising from the neo-extractive activity of minerals favor the deforestation of protected areas and / or indigenous territories, particularly due to the illegal mining that crosses the borders of the state of Amapá (French Guiana and Suriname), the which makes it possible to observe that, despite the legal framework, the neo-extractive mining activity is responsible for favoring a degradation of the Amazonian biome, with the presence of land grabbing, the creation of highways, in addition to affecting the traditional mode.
Turismo e áreas protegidas : tendências globais e desafios para a integração de políticas públicas
Authors: Irving Marta de Azevedo , Lima Marcelo Augusto Gurgel de , Nasri Yasmin Xavier Guimarães
Published: April 2022

O turismo representa um fenômeno contemporâneo complexo, associado a dimensões econômicas, sociais, ambientais, éticas, políticas e simbólicas e, para a sua interpretação, se pressupõe uma leitura teórica multidimensional e, por consequência interdisciplinar, mediada por uma perspectiva política crítica. Mas apesar disso, as políticas públicas de turismo são predominantemente desenvolvidas pela lógica de mercado ou por um viés econômico e dissociadas das demais políticas setoriais, o que tende a mascarar algumas questões essenciais em planejamento turístico. Com base nesses antecedentes, o presente artigo tem como objetivo mapear, preliminarmente, as tendências globais, em termos de políticas públicas dirigidas à conservação da biodiversidade, em sua articulação com o turismo, com ênfase nas áreas protegidas. A pesquisa qualitativa foi orientada por levantamento e análise bibliográfica e documental, considerando o período de 1992 - pactuação da Convenção sobre Diversidade Biológica (CDB) - e 2019, marco de inflexão do início da Pandemia da Covid 19. Pela análise realizada é possível afirmar que são evidentes os esforços, no plano global, desde a CDB, para a articulação entre as políticas públicas de conservação da biodiversidade e turismo. No entanto, esse movimento é ainda incipiente diante dos riscos crescentes à biodiversidade e da urgência para a retomada do turismo, em bases sustentáveis, no contexto pós Pandemia da Covid 19.

Il s’agit dans cet article de présenter le positionnement des personnes impliquées par la réorganisation de la grille-horaire. Le problème de recherche cherche à répondre à la question suivante : comment les différentes parties prenantes perçoivent-elles ce réaménagement de la grille horaire en termes de conciliation des temps scolaire et extrascolaire, de partenariat et de justice scolaire ?
L’éducation au politique à travers les questions environnementales : ancrages épistémologiques et alignement avec l’éducation au développement durable
Authors: Slimani Melki
Published: April 2022

Les apprentissages politiques concernant les questions environnementales sont disséminés dans les « éducations à ». Ils se retrouvent aussi au croisement de différentes logiques éducatives formelle, non formelle et informelle. Il en résulte la double fragilité épistémologique et pédagogique de tels apprentissages. Cet article aborde la problématique du besoin d’ancrages épistémologiques et pédagogiques supportant la construction de curriculums appropriés pour une éducation au politique à travers les questions environnementales. Dans une première partie, les apprentissages politiques sont formalisés selon une perspective épistémologique qui les considère comme des processus de production d’un savoir politique. Puis, dans une deuxième partie, des ancrages pédagogiques sont explorés en termes de relations productives possibles entre les apprentissages politiques et les apprentissages associés à aux Objectifs de développement durable (ODD).
L’université à l’ère de l’anthropocène : repenser l’éducation au politique par l’écologie
Authors: Point Christophe
Published: April 2022

Ce travail imagine un dialogue fictif entre Hannah Arendt et Greta Thunberg au sujet de la place de l’écologie politique à l’université. Ainsi, l’objectif de notre travail est d’interroger le cadre théorique nécessaire à l’inscription à l’université d’une éducation à l’écologie politique. Dans un premier temps, nous interrogeons ce qui empêche pour l’heure de développer une véritable pédagogie universitaire sur ce sujet. Plus spécifiquement, nous prenons l’exemple de la pensée de Hannah Arendt pour illustrer les dualismes conceptuels entre l’enfant et le monde, l’éducation et la politique, l’éducation et l’instruction, qui, selon nous, nous empêchent de penser pédagogiquement et politiquement la place de l’écologie au sein des universités. Les dégâts de ces dualismes sont ensuite illustrés à partir de notre façon d’appréhender l’éco-anxiété. Enfin, nous proposons quelques pistes prospectives et générales pour inscrire l’écologie comme cadre épistémologique de recherche, d’enseignement et de formation universitaires.

Big Five Personality Traits Prediction Using Brain Signals
Authors: Arya Resham , Kumar Ashok , Bhushan Megha , Samant Piyush
Published: April 2022

Brain activity ensures the identification of emotions that are generally influenced by the personality of an individual. Similar to emotions, there exists a relationship between personality and brain signals. These brain signals could be of a mentally healthy person or someone having psychological illness as well. In this paper, first, the survey related to work done on the personality prediction of healthy subjects is explored. Thereafter, the relationship between personality and psychologically ill subjects is also briefly presented based on the existing literature. Following this, an analysis of physiological signals (EEG) is also done for more understanding of personality prediction. ASCERTAIN – a multimodal database for implicit personality and recognition, is considered. It contains EEG recordings and self-annotated big five personality values of 58 students. Some time and frequency domain features are extracted and then put into various classifiers to predict the personality in five dimensions.
An Iterative CrowWhale-Based Optimization Model for Energy-Aware Multicast Routing in IoT
Authors: Shende Dipali K. , Angal Yogesh S. , S.C. Patil.
Published: April 2022

This paper proposes an energy-aware multicast routing protocol (MRP) based on the optimization algorithm named iterative Crow Whale-Energy Trust routing (iterative CrowWhale-ETR). The CrowWhale-ETR is developed by including the historical terms from Taylor series in the CrowWhale optimization algorithm. Initially, the effective nodes for the multicast routing process are considered by measuring the trust and energy level of nodes. Based on the fitness factor, the protected nodes are selected relies on the trust and energy level of individual nodes. Once the secure nodes are selected, route detection and route selection is performed based on iterative CrowWhale-ETR. Finally, the route maintenance is done as per the remaining energy and trust factors of the nodes in the network. The comparative analysis of developed iterative CrowWhale-ETR is performed with the evaluation metrics, like energy, delay, throughput and detection rate using 50 and 100 nodes in the presence as well as absence of attacks.
Political Trust as a Judgement Heuristic in Predicting Readiness to Comply With Governmental Restrictions During the COVID-19 Pandemic
Authors: Austers Ivars , Dimdins Girts , Leja Veronika , Gaina Viktorija
Published: April 2022

The present study was designed to determine the extent to which political trust in government serves as a judgment heuristic in predicting readiness to comply with governmental restrictions during the COVID-19 pandemic. Through an online study of 1,429 respondents, we found that trust in government and the evaluation of government actions during the COVID-19 pandemic were the strongest predictors of readiness to comply with government restrictions aimed at mitigating the pandemic (in addition to the previous restriction-compliant behaviour of the respondent). This pattern of results shows that government-related judgments play an important role in predicting one's readiness to engage in mitigating actions in the future. These two variables seem to be central in terms of uniting all the variables which potentially predict mitigating behaviour: an evaluation of the government’s competence, benevolence, integrity, and the perceived risk of the government’s actions with respect to oneself and one’s family, as well as with respect to the evaluation of economic prospects.

Published: April 2022

One way to reduce mineral fertilizers is to use alternative fertilizers instead, such as the byproducts from the food industry. In the present study we evaluated the effects of sugarcane bagasse ash on the physiology, growth, and development of sunflowers (Helianthus annuus L.). We conducted an experiment in a greenhouse using a completely randomized design with two sunflower cultivars (Multissol and Catissol), five sugarcane bagasse ash doses (0.0, 3.125, 4.687, 6.25, and 7.812 mg ha-1), and 5 replicates. At 85 days after planting we determined the plant height; leaf number; stem diameter; internal and external diameter of the flower chapter; leaf area index; shoot dry weight; net assimilation rate; dry mass production rate; relative and absolute growth rate; extravasation of electrolytes; relative water content; photosynthetic pigments (chlorophyll a, b, carotenoids, and the chlorophyll a/b ratio); and soluble carbohydrates, proteins, and proline. The height, number of leaves, and shoot dry mass increased due to the availability of nutrients contained in the ash. The incorporation of ash into the soil increased the photosynthetic activity (chlorophyll a and b) of both sunflower cultivars. The diameter of the stem, leaf area index, and relative growth rate of both sunflower cultivars increased with increasing ash dose. Therefore, the ash can be used as an alternative fertilizer, complementing or replacing mineral fertilizers.

Published: April 2022

The study investigated meat quality of bulls fed concentrate feeds and hay. The treatments were hay ad libitum + dried cafeteria leftover 4 kg DM d-1 (D1); hay ad libitum + wheat bran 4 kg DM d-1 (D2); hay ad libitum + 4 maize grain 4 kg DM d-1 (D3); hay ad libitum + mix 4 kg DM d-1 (1:1, wheat bran to maize grain, respectively (D4)); hay ad libitum + scrambled whole groundnut 4 kg DM d-1 (D5); and hay ad libitum + mix of each ingredient 4 kg DM d-1(D6)). Samples from longissimus lumborum muscle were taken in triplicate. Beef from bulls fed D5 had highest (p < 0.05) protein and fat than those fed other treatments. However, bulls finished in D3 had similar fat to those fed with whole ground nut. Highest meat tenderness (p < 0.05) recorded at 24th followed by 16th d than those aged on other periods. Beef from D6 produced lean meat, which is acceptable to consumer and market demand than D3, produced carcass with highest fat coverage This study confirmed that meat from D6 had an acceptable quality attribute suggesting the breed could serve as a potential source in red meat industry.

Published: April 2022

Paiche (Arapaima gigas) belongs to the Kingdom Animalia, Phylum Chordata, Class Actinopterygii, Order Osteoglossiformes, Family Arapaimidae, Genus Arapaima, and its origin may date to the Jurassic period. The species has natural habitat in the Amazonian rivers, found mainly in marginal lakes, being considered an important fishing resource, with high market value and high demand for meat and leather in both Brazilian and international trade. This study aims to report the morphology of the esophagus and stomach by light microscopy and scanning electronics microscopy. The esophagus was presented as muscular, short, tubular and fan-shaped in the cranial portion, also presenting deep longitudinal folds, and the entire mucosa is covered by mucus secretory cells with distinct morphological characteristics. Pirarurcu’s stomach has a J-shape divided into three regions: cardiac with a lighter aspect, fundus portion with few folds in the mucosa, and pyloric with deeper folds, also presenting gastroliths in fundus and pyloric portions. Both microscopy studies highlighted three glandular regions, composed by mucoid columnar epithelial cells, gastric crypts with different shapes and sizes depending on each portion, in which the different shapes of the mucosal folds in each region of the stomach were evident, and digitiform microsaliences were found in the cardiac region, and micro-orifices and desmosome in the fundus region. Also, fundus and pyloric portions produce more mucus than the cardiac. Then morphology found was consistent with the eating habits and management of distinct characteristics of the digestive tract.

Published: April 2022

Oeceoclades maculata is a terrestrial orchid species that has potential for commercial purposes. Taking that into consideration, the present investigation aimed at studying its germination and initial development in vitro as well as its acclimatization. The influence of Murashige and Skoog (MS), Knudson C (KC), and Vacin and Went (VW) media in the presence and absence of 0.3% activated charcoal on in vitro germination and protocorm development were investigated. The effects of different concentrations of BA in combination with 0.5 mg L-1 NAA on seedling multiplication and growth were evaluated. The possibility of using dark-grown stem segments for micropropagation and acclimatization under laboratory and field conditions was also assessed. The results indicated that the most adequate media for germination were full-strength MS enriched with activated charcoal or KC supplemented with 1.5 mg L-1 BA in combination with 0.5 mg L-1 NAA. In terms of protocorm development, KC supplemented with 1.5 mg L-1 BA alone or in combination with 0.5 mg L-1 NAA provided the best results. The addition of 1.5 mg L-1 BA in combination with 0.5 mg L-1 NAA to KC medium favored the best results for seedling multiplication and development. The use of dark-grown stem segments is a viable alternative for the micropropagation of O. maculata. Regarding acclimatization, 100% survival of plants was observed during the initial phases and under field conditions average survival was 53.33%.
Naïve realism and the phenomenology of perception and memory
Authors: Fish William
Published: April 2022

In this paper, I begin to explore what a naïve realist might say about the phenomenology of episodic memory. I start by arguing that, when it comes to accounting for the phenomenology of memory experiences, there are two primary options available to the naïve realist: to treat memory phenomenology along the same lines as perceptual phenomenology – as involving phenomenal character that is grounded in acquaintance with the external environment – or to treat memory as lacking such acquaintance-based phenomenal character, and then attempting to account for there being something it is like to remember as being somehow inherited from cases that do have phenomenal character. I then explore the prospects of providing an account of the phenomenology of episodic memory in both ways, before tentatively coming down in favour of the latter approach
Introduction: philosophy of memory
Authors: Sant'Anna André Rosolem
Published: April 2022

Philosophical theorizing about the nature of memory is becoming increasingly prominent in the recent literature, with the philosophy of memory now being recognized as a distinct field of research (Michaelian & Sutton, 2017; Bernecker & Michaelian, 2017). As Michaelian et al. (2018) note in their introduction to a recent edited collection, this is attested by the large number of articles, journal special issues, books, and edited collections published recently, as well as the various conferences that have been organized in different parts of the world in the past few years. There is, to put it differently, a growing sense of community among philosophers of memory. But what is the philosophy of memory? What sort of questions are philosophers of memory concerned with?

Este ensaio sugere que a forma multifacetada, fragmentada e heterógena que caracteriza a originalidade do romance Serafim Ponte Grande, de Oswald de Andrade, pode também ser lida como resultante mimético de um processo de apreensão de um modo subjetivo que se mostra evidente e preponderante a partir do século XX
O O lugar franco-brasileiro de Cenas da natureza nos trópicos
Authors: Moraes Ariston
Published: April 2022

Este artigo analisa o argumento de Cenas da natureza nos trópicos e sua influência sobre a poesia, escrito por Ferdinand Denis (1824), a partir de uma reflexão sobre a relação entre o postulado do livro e suas principais referências teóricas. Esta análise, com o objetivo de compreender o lugar e a importância dessa publicação na história literária franco-brasileira, ainda faz uma comparação entre a proposta de Ferdinand Denis em despertar a literatura francesa para as paisagens dos trópicos e a reação dos principais críticos franceses ao pensamento do escritor. Por meio desta análise, observa-se que, ao contrário do Brasil, onde serviu de repertório temático à criação do romantismo brasileiro, Cenas da natureza nos trópicos, assim como a figura de Ferdinand Denis, foi rejeitado pelos literatos franceses devido à limitação das suas propostas teóricas.
Vozes femininas decoloniais em Redemoinho em dia Quente, de Jarid Arraes
Authors: Leites Amália Cardona , Dalcin Camila
Published: April 2022

Neste artigo desnudamos os contos de Redemoinho em dia quente (2019), de Jarid Arraes para reconhecermos as vozes decolonias que habitam as narrativas e ecoam resistência às violências cotidianas vivenciadas pelo ser mulher. Daremos especial atenção a três contos: ‘Cinco mil litros’; ‘Telhado quebrado com gente morando dentro’ e ‘Gesso’. Estes contos foram escolhidos porque compartilham a resiliência como modo de sobrevivência entre mulheres que subvertem seus destinos ao não aceitarem os abusos físicos, sexuais e financeiros e que, portanto, não se permitem colonizar.  Também é fundamental a este trabalho o reconhecimento da importância de vozes como a de Arraes, mulher, negra e nordestina no cenário literário contemporâneo. A voz de Jarid destaca-se, sobretudo, por sua tomada de posição e entendimento do seu fazer político através da sua literatura. Dentre as conclusões possíveis, a mais urgente é a necessidade de que cada vez mais vozes como a de Jarid Arraes ocupem o campo literário e tomem a cena ficcional brasileira: mulheres que fazem literatura com as feridas que carregam nos seus corpos e que com as marcas de suas ancestralidades, conquistam novos espaços.

Published: April 2022

In this work, we applied different extrapolation techniques in association with the multigrid method to discover which one is the most effective in reducing the iteration error and the processing time (CPU time), as well as in improving the convergence factors. The mathematical model studied refers to the two-dimensional laminar flow of an isothermal time-dependent incompressible fluid modeled by the Navier-Stokes equations, with , solved iteratively with the projection method and the Finite Volume Method. The extrapolation methods used were: Aitken, Empiric, Mitin, scalar Epsilon, scalar Rho, topological Epsilon, and topological Rho. A two-step application was performed: first, extrapolators methods were applied individually after the use of the multigrid method. Then, the best-performing extrapolation techniques were used in the second step, where they were applied between the cycles of the multigrid method. The methods that presented the best convergence properties in the first stage were topological and scalar Epsilon. In the second stage, both methods maintained their performance, however, the topological Epsilon method presented more significant convergence rates than the scalar Epsilon. The other parameters analyzed were: the storage memory peak, the dimensionless norm of the residual based on the initial estimate, and the error norms of iteration. Thus, it was possible to state which extrapolation technique performed best and to compare it with the multigrid method with no extrapolation, which in this study was the topological Epsilon method.

The study evaluated the production of proteases in solid-state fermentation using wheat bran as a substrate. The best producing isolates were used to obtain crude extract which was evaluated for optimal pH and temperature, thermostability, effect of salts and activity against inhibitors. The studied fungi were Aspergillus sp. 125, Fusarium sp. 132, Fusarium sp. 206, Pleurotus albidus 018 and Pleurotus pulmonarius CCB20. The isolates with better results (Aspergillus sp. and P. albidus), showed protease activity with an optimum pH of 7.0, and an optimum temperature of 50ºC with good thermostability between 40 and 50ºC. As for salts, the protease activity was inhibited in the presence of ZnSO4, and the activity of the proteases from the crude Aspergillus extract, strongly inhibited by PMSF, indicating the presence of a fraction of serine protease in the extract. The extracts of the two selected isolates showed considerable inhibition by EDTA. The milk clotting activity was 240 U mL-1 for the Aspergillus extract and 153 U mL-1 for the crude P. albidus extract. Proteases are important enzymes widely used in the food industry, including cheese. The data suggest that these fungi have the potential to produce these enzymes for usage in cheese making
Extracting feature requests from online reviews of travel industry
Authors: Kumari Superna , Memon Zulfiqar Ali
Published: April 2022

Before product development, Requirement Engineering (RE) is the fundamental need to know customer preferences for any product. Traditionally, RE is carried out in several ways, particularly by conducting interviews, questionnaires, surveys etc. but these methods provide limited amount of data. As user’s preferences vary from country to country for any type of application, it is very hectic and time consuming to collect user requirements from different countries manually. As the internet is widely used now a days, a large number of customer’s reviews are available online that can be used to obtain the requirements for any product without manual work. Online customer reviews can be divided into three types: user experience, bugs and feature requests. Among these 3 categories, feature requests can be very useful for stakeholders (analysts/ requirements engineers) to acquire the requirements of each application. So, the approach is proposed for feature requests extraction from mobile application reviews of travel industry. In this paper, 4 categories of mobile apps of travel industry belonging to 5 countries have been extracted from Google Play Store and Apple Store. For each category, data from 5 different mobile applications have been considered. Since, the review of users from different countries is in their respective language, those reviews are translated into a standard language i.e. English, and then feature requests from these reviews have been extracted. After that, features are retrieved from user reviews and topic modeling is performed on extracted features since one or more features can be modelled under one topic. To know the opinions of users for any feature request, sentiment analysis is also performed on feature request sentences. These feature requests are also classified as Functional and Non-functional Requirements since it is very useful for application developers to improve or maintain the product to better facilitate the application users

Irrigation is a practice that increases productivity and enables the expansion of agricultural borders. This practice should be well managed to ensure the efficient use of water by plants, and such management requires specialized labor, which increases operating costs. Therefore, the main objective of this study is the implementation of an automated irrigation system that considers factors ranging from  water demand to the operation of the system. Because the daily water demand is determined by crop evapotranspiration,  a low-cost weather station was developed to acquire data daily. Such data can be used to estimate the reference evapotranspiration (ET0) using the Penman-Monteith model of the Food and Agriculture Organization (FAO). Thus, by combining the amount of water required by a crop with the physical  and hydraulic properties of the soil and the hydraulic properties of the irrigation system, it was possible to determine the daily frequency and amount of time required for the system to operate to meet the water requirements of the    crop without undergoing stress from a deficit or an excess of water. The management/monitoring system was designed and implemented to allow the  user to access data remotely through an online application. This application enables the real-time transmission of irrigation-related data, such as weather station data and system logs, obviating the need for the user to be present at the crop site. This allows the supervision of many areas simultaneously with low cost

Background

Documentation presents an overwhelming burden to bedside clinical nurses. Nurses must manually enter several hundred data points into electronic health record flow sheets, taking time from direct patient care and introducing opportunity for documentation errors.

Local Problem

A patient record audit revealed a significant gap in documented patient repositioning events. This quality improvement initiative evaluated automated repositioning documentation via a wearable sensor system.

Methods

A pretest-posttest design was used to examine retrospectively collected manual documentation and prospectively collected sensor documentation of patient repositioning events in a 148-bed rural community hospital. Repositioning documentation manually entered into electronic health records during the baseline period (January 1 to February 28, 2018) was compared with automatic, sensor-based repositioning documentation during the implementation period (corresponding months in 2019 and 2020 to eliminate seasonality).

Results

A convenience sample of 105 patient records was reviewed. The mean documented patient repositioning interval was 6.6 hours in the baseline period and 2.4 hours in the implementation period. The improvement was most pronounced in patients with obesity, whose mean repositioning interval improved from 9.4 hours to 2.5 hours. Documentation compliance (actual vs expected repositioning documentation) was 31% with manual documentation and 82% with automatic sensor-based documentation.

Conclusions

Repositioning was documented more than 2.5 times as frequently with sensor technology as with manual data entry. Body position and reasons for delayed repositioning events were documented more completely with sensor technology. Automated documentation may improve the accuracy of electronic health records and reduce the documentation burden for nurses.
Effects of an Electronic Health Record Tool on Team Communication and Patient Mobility: A 2-Year Follow-up Study
Authors: Anderson Robert
Published: April 2022

Background

Intensive care unit early mobility programs improve patients’ functional status and outcomes. An electronic health record–based communication tool improved interprofessional communication within an early mobility program. Long-term sustainability of this communication tool has not been evaluated.

Local Problem

Ineffective interprofessional communication was perceived as a barrier to success of an intensive care unit early mobility program at the project institution. An electronic health record–based communication tool was successfully implemented to improve communication. Sustaining the intervention is of continued importance.

Methods

Longitudinal data were collected 2 years after initial implementation of the communication tool to evaluate its continued impact on patient outcomes and staff engagement with an intensive care unit early mobility program.

Results

Initial implementation of the electronic health record–based communication tool resulted in statistically and clinically significant improvements in patient and staff metrics. Compared with postimplementation data, 2-year longitudinal follow-up data revealed nonsignificant changes in patient outcomes (time from admission to mobility goal, mechanical ventilation duration, length of intensive care unit stay, and discharge disposition recommendations to higher independence levels). Staff reported continued use of the communication tool and positive perceptions of its impact on the intensive care unit early mobility program.

Conclusions

Nonsignificant changes in patient outcomes may indicate sustainment of the effect of the communication tool’s original implementation. Employing appropriate sustainment techniques is essential to maintain practice change. The electronic health record–based communication tool can improve interprofessional communication within an intensive care unit early mobility program, improving patient outcomes and staff teamwork.
Using a Standardized Rounding Tool to Improve the Incidence of Spontaneous Awakening and Breathing Trials

Published: April 2022

Background

Spontaneous awakening and breathing trials have been associated with shorter durations of mechanical ventilation and intensive care unit lengths of stay.

Local Problem

Inconsistent spontaneous awakening trials and spontaneous breathing trials, mechanical ventilation weaning strategies, and interdisciplinary rounding processes contributed to prolonged mechanical ventilation duration and length of stay in a 44-bed adult medical intensive care unit. Methods A standardized rounding tool that focused on coordinating spontaneous awakening and breathing trials, and on their outcomes, was integrated into daily multidisciplinary rounds in a medical intensive care unit. Aggregated patient data from the 4-month project implementation phase were compared with historical data collected for 2 months before project implementation.

Results

During the 2-month preintervention phase, 613 adult patients were managed in the medical intensive care unit and 41 patients required mechanical ventilation, whereas during the 4-month intervention phase, 1271 patients were managed in the unit and 96 patients required mechanical ventilation. The project was associated with a 24% (0.89-day) reduction in the mean length of stay (3.72 vs 2.83 days) and a 46.3% (2.81 day) reduction in mechanical ventilation duration (6.06 vs 3.25 days) when comparing August 2019 to January 2020.

Discussion

A standardized rounding tool emphasizing a coordinated process for spontaneous awakening and breathing trials was associated with a shorter length of stay and duration of mechanical ventilation among patients in the medical intensive care unit.

Conclusion

An evidence-based approach to weaning from mechanical ventilation and standardized rounding may be a cost-effective way to reduce mechanical ventilation duration and length of stay in a medical intensive care unit.
Virus-Specific Regulatory T Cells Persist as Memory in a Neurotropic Coronavirus Infection

Regulatory T cells (Tregs) are critical for regulating immunopathogenic responses in a variety of infections, including infection of mice with JHM strain of mouse hepatitis virus (JHMV), a neurotropic coronavirus that causes immune-mediated demyelinating disease. Although virus-specific Tregs are known to mitigate disease in this infection by suppressing pathogenic effector T cell responses of the same specificity, it is unclear whether these virus-specific Tregs form memory populations and persist similar to their conventional T cell counterparts of the same epitope specificity. Using congenically labeled JHMV-specific Tregs, we found that virus-specific Tregs persist long-term after murine infection, through at least 180 d postinfection and stably maintain Foxp3 expression. We additionally demonstrate that these cells are better able to proliferate and inhibit virus-specific T cell responses postinfection than naive Tregs of the same specificity, further suggesting that these cells differentiate into memory Tregs upon encountering cognate Ag. Taken together, these data suggest that virus-specific Tregs are able to persist long-term in the absence of viral Ag as memory Tregs.

In stroke patients, infection is a significant contributor to morbidity and mortality. Moreover, older stroke patients show an increased risk of developing stroke-associated infection, although the mechanisms underlying this increased susceptibility to infection are unknown. In this study, using an experimental mouse model of ischemic stroke, we showed that older (12–15 mo of age) mice had elevated lung bacterial infection and inflammatory damage after stroke when compared with young (8–10 wk of age) counterparts, despite undergoing the same degree of brain injury. Intravital microscopy of the lung microvasculature revealed that in younger mice, stroke promoted neutrophil arrest in pulmonary microvessels, but this response was not seen in older poststroke mice. In addition, bacterial phagocytosis by neutrophils in the lung microvasculature was reduced by both aging and stroke, such that neutrophils in aged poststroke mice showed the greatest impairment in this function. Analysis of neutrophil migration in vitro and in the cremaster muscle demonstrated that stroke alone did not negatively impact neutrophil migration, but that the combination of increased age and stroke led to reduced effectiveness of neutrophil chemotaxis. Transcriptomic analysis of pulmonary neutrophils using RNA sequencing identified 79 genes that were selectively altered in the context of combined aging and stroke, and they were associated with pathways that control neutrophil chemotaxis. Taken together, the findings of this study show that stroke in older animals results in worsening of neutrophil antibacterial responses and changes in neutrophil gene expression that have the potential to underpin elevated risk of stroke-associated infection in the context of increased age.

This paper presents an innovative digital method to analyse agricultural tire profiles based on pictures. From this method, we can conclude that the tire deformation is caused by the changes in vertical load and inflation pressure. The first stage in this method is 3D-scanning; the vertical cross-section is created from the obtained picture of the tested tire. From this cross-section, the deflection of the tire can be determined. Then, the horizontal cross-section is created - this operation allows determining the tire’s contact area at the highest vertical deformation. Obtained results can be useful to create the tire deformation characteristic. In turn, the contact pressure values can be determined (even through laboratory testing, without research in field conditions). The knowledge about contact pressure allows taking some actions to reduce soil compaction. In the description of the method, the radial tire was used, but the structure and equipment of the test bench allow the use of cross-ply tires with different dimensions.
