Published: August 2024

BACKGROUND AND OBJECTIVES

High-flow nasal cannula (HFNC) is used in up to 50% of children admitted with bronchiolitis. Consensus recommendations for feeding these children have not been established, and there is variability in practice. We sought to identify factors influencing feeding decisions for general care patients admitted with bronchiolitis on HFNC from a national sample of interdisciplinary care team members.

METHODS

In this qualitative study, we conducted semi-structured virtual interviews with care team members involved in making feeding decisions at 10 US hospitals from June 2022 to March 2023. Eligible participants included 1 nurse, respiratory therapist, speech language pathologist, and physician from each site. Interviews were audio-recorded, transcribed, and conducted until reaching sufficiency. Three researchers analyzed transcript data using content analysis guided by the Systems Engineering Initiative for Patient Safety 2.0 model.

RESULTS

We interviewed 29 participants, including 19 nurses, respiratory therapists, and speech language pathologists and 10 physicians. Participants identified 11 factors influencing feeding decisions related to hospital work systems and processes outlined in the Systems Engineering Initiative for Patient Safety model, including people (child and parent characteristics, care team experience), tools and technology (guideline, protocol, ordersets), organization (institutional culture, education), environment (time of day, care location), task (interventions to optimize feeding), and process (clinical assessment, feeding trial, communication).

CONCLUSIONS

Our findings suggest that feeding decisions are driven by factors related to the child, care team experience, institutional tools, and culture. These key factors may inform local improvement efforts to decrease variation in feeding children with bronchiolitis requiring HFNC.
First-order planar autoregressive model
Authors: Shklyar Sergiy
Published: August 2024

This paper establishes the conditions for the existence of a stationary solution to the first-order autoregressive equation on a plane as well as properties of the stationary solution. The first-order autoregressive model on a plane is defined by the equation

\[ {X_{i,j}}=a{X_{i-1,j}}+b{X_{i,j-1}}+c{X_{i-1,j-1}}+{\epsilon _{i,j}}.\]

A stationary solution X to the equation exists if and only if $(1-a-b-c)(1-a+b+c)(1+a-b+c)(1+a+b-c)\gt 0$. The stationary solution X satisfies the causality condition with respect to the white noise ϵ if and only if $1-a-b-c\gt 0$, $1-a+b+c\gt 0$, $1+a-b+c\gt 0$ and $1+a+b-c\gt 0$. A sufficient condition for X to be purely nondeterministic is provided.
An explicit expression for the autocovariance function of X on the axes is provided. With Yule–Walker equations, this facilitates the computation of the autocovariance function everywhere, at all integer points of the plane. In addition, all situations are described where different parameters determine the same autocovariance function of X.

Published: August 2024

Functional regression has been a hot topic in statistical research. However, not much work has been done when response variables are cross-sectionally dependent variables and explanatory variables contain a real-valued scalar variable and a functional-valued random variable. In this paper, we consider a new functional partially linear spatial autoregressive model. Based on the functional principal components analysis and basis function approximation, we obtain the estimators of the unknown parameter and functions through the instrumental variables estimation method. The asymptotic normality and convergence rates of estimators are proved under some mild conditions. In addition, we illustrate the finite sample performance of the proposed estimation method through simulation study and a real data analysis.

Relying on the development of radio electronics and computer technology, a direction has emerged in radar meteorology related to the development of methods and means for remote measurement of the vertical wind profile in the atmosphere by determining the Doppler frequency shift of the reflected signal from meteorological irregularities. The article provides a brief overview of the use of wind parameter radars (profilers) that operate in the decimeter wavelength range (400–1700 MHz), since it is in this range that wind parameters are most fully determined under absolutely clear sky conditions. The distribution of profilers across countries and continents is considered, their main technical characteristics are given, and the current situation in the Russian Federation is described.

The article is devoted to the problem of determining the aspect angle of a surface ship based on its radar image obtained in synthetic aperture radars. Among the main methods of solving this problem are the classical Bayesian method of multi-alternative hypothesis testing and its modifications, and/or the method of classifying surface ships located at different angles using artificial neural networks (ANNs). The study demonstrates that achieving high efficiency in aspect recognition using ANNs requires significant computational resources, as well as an access large, representative, and scalable training dataset. ANNs demonstrates high performance in various observation conditions in case sufficient computational and time resources; however, it is noteworthy that their effective training requires a substantial amount of processing time, reaching several hours. At the same time, classical methods are capable of performing calculations in fractions of a second, even on relatively low-powered devices. It is also worth noting that as the number of recognised classes increases, ANNs may consume up to tens of gigabytes of RAM, limiting the accessibility of this method in the aspect of task recognition of spatially distributed targets.

Authors:   Research Institute of Radio Engineering Systems, Tomsk State University of Control Systems and Radioelectronics, Gogadze I. S.
Published: August 2024

The paper explores the effectiveness of modular coding for transmit- ting information message under low bit energy/noise ratio conditions. The analysis was conducted as part of the project aimed at enhancing the current GLONASS system and involved comparing it with the truncated Hamming code (85,77). During the analysis, we have calculated the minimum arithmetic operations needed to encode both codes and assessed the noise immunity of modular coding. When comparing the required arithmetic operations for coding, modular code only holds an advantage in cases where the numerical information is comparable to the bases of the system. Additionally, its noise immunity is inferior when transmitting the same amount of information bits as in the Hamming code. However, when reducing the bases of the system, modular code prevails. Additionally, it is worth noting that the system possesses certain features, such as the ability to process the coded information in parallel and flexible methods of decoding the information.

Published: August 2024

In radiophotonic microwave transmission systems, as in any radioelectronic systems, noise characteristics determine the potential of accuracy and range. As a measure of the difference between the noise characteristics of optoelectronic microwave signal converters from ideal ones, the use of the noise figures of the elements included in their composition is proposed. The effect of such a criterion is demonstrated by the example of the optoelectronic microwave oscillator (OEO). Based on the results of the study of the optoelectronic microwave oscillator noise parameters quantitative characteristics of the conversion of the OEO elements noise sources into phase and amplitude fluctuations of the output microwave oscillation are obtained. The analysis of the interaction of the OEO elements noise with the microwave harmonic oscillation is performed. The technique for measuring the noise conversion characteristics using the noise figure has been developed. The results of measuring characteristics of the interaction of harmonic oscillation with the optoelectronic components additive and multiplicative noise of optoelectronic components are presented. Based on the values of the noise figure, the possibilities of reducing the noise levels of microwave signal converters are evaluated and recommendations are made to reduce the influence of the noise.

TRAINING TEACHERS IN A COLLECTIVE: SOME GUIDING PRINCIPLES
Authors: BINSFELD CARINE DAIANA , LOPES ANEMARI ROESLER LUERSEN VIEIRA
Published: August 2024

ABSTRACT: This study falls within the field of research focused on teacher training, aiming to understand how these professionals are trained in a collective context, such as a study and research group. This article presents an interpretation of actions carried out in a study and research group, which, based on certain principles, can guide the teacher training of the participants. The intention is to view this training from the perspective of activity, based on the premise that a collective study and research group that emphasizes actions beyond its structural dimensions offers training that, with new qualities, transforms the individuals involved. Thus, a research was developed based on the premises of Historical-Cultural Theory, with the objective of understanding the principles that guide teacher training in a collective. Data were produced through the analysis of actions carried out in a study and research group with 18 members, comprising undergraduate students, teachers pursuing postgraduate studies, and/or teachers from Basic Education or Higher Education participating in its projects. The analytical process, grounded in the dialectic between the guiding and executing dimensions, sought to identify guiding principles of teacher training in the group through the various actions it develops. The results indicate that these actions allow the principles to be actualized, facilitating the formation of individuals from the perspective of a collectivist personality, based on the affective-cognitive unity constituted in the process of participating in the group/collective, which can contribute to the personality development of the individuals involved.
THE CONCEPT OF POST-CRITICAL CURRICULUM IN PHYSICAL EDUCATION: A GEOPHILOSOPHICAL ANALYSIS
Authors: VIEIRA RUBENS ANTONIO GURGEL , BONETTO PEDRO XAVIER RUSSO , BORGES CLAYTON CÉSAR DE OLIVEIRA
Published: August 2024

ABSTRACT: This study aims to problematize the concept of post-criticality in curricular uses in the field of school Physical Education. To this end, we used theorizations from both the philosophical and educational fields, as well as their effects on the epistemological discussions of the aforementioned component. As a working method, we took as inspiration the concept of geophilosophy from the French philosophers Gilles Deleuze and Félix Guattari (Deleuze; Guattari, 2010). At first, based on its territorialization in the curricular field and its reterritorialization in Physical Education, we highlight the conditions of immanence and the potential of the concept in question and then de-territorialize it, pointing out the risks that accompany classificatory thinking. As a final reflection, we propose a radicalization of the differential process in curricular production, positioning all propositional minority creations in the field of Physical Education as important for a fairer and less violent society, requiring the continuity of work that avoids reductionism and sectarianism.

Resumo: Este trabalho tem como propósito introduzir e aprofundar a aplicação do método de Process Tracing (PT) na análise de estudos de caso como teste de teoria em Relações Internacionais (RI), focando especialmente em pesquisadores brasileiros. Inspirado pelo crescente uso e importância do PT, visa oferecer uma estrutura para sua utilização na modalidade de teste de teoria, auxiliando aqueles que buscam adaptar teorias de RI para avaliar casos específicos. Utilizando como exemplo a institucionalização da US Commission on International Religious Freedom (USCIRF) nos Estados Unidos, o artigo se baseia na estruturação do método para sistematizar o teste da teoria do Novo Liberalismo de Moravcsik (1997). O texto apresenta o caso de forma estruturada, demonstrando como o PT pode ser aplicado em estudos centrados na teoria. Além disso, oferece um mecanismo causal teórico específico sobre o lobby religioso institucionalizado da USCIRF. Este trabalho não se limita a ser um estudo de caso único, mas sim um esforço metodológico para orientar pesquisadores interessados em operacionalizar teorias de RI usando PT como teste de teoria. Com isso, busca-se aprimorar o rigor e a clareza na pesquisa qualitativa em RI, contribuindo para a crescente utilização do PT entre os pesquisadores brasileiros interessados nessa área, promovendo avanços significativos na compreensão dos mecanismos causais em contextos políticos complexos.

ABSTRACT: Owing to rich in vitamins, proteins, mineral elements, and active substances, the highly medicinal and economic value of mung bean seeds have been proven to be beneficial to human. In order to fully identificate and innovative utilization of excellent germplasm resources for mung bean yield and quality breeding, the genetic diversity level of eight seed phenotypic traits of 302 mung bean germplasm resources were comprehensively evaluated by diversity analysis, correlation analysis, principal component analysis (PCA), and cluster analysis. The results showed the genetic diversity of eight seed phenotypic traits of 302 mung bean germplasm resources with a Shannon diversity Index ranging from 0.25 to 2.09. For most traits, their coefficient of variation (CV) were more than 10% with the highest being seed shape (41.51%). Correlation analysis showed that the 100-seed weight had extremely positive correlations with seed size, seed length, seed width, and seed thickness. PCA of seed phenotypic traits showed that the cumulative contribution rate of the first three principal components was 78.551%. These principal components included seed width, seed coat gloss and seed color. The 302 mung bean germplasm resources were divided into eight groups by cluster analysis. A total of 140 germplasm resources with large-seed were selected from group I and group II, of which 9 germplasm resources in group II were likely to be high-yield varieties. Overall, this study not only indicated sufficient variation among the studied germplasm resources, but also provided a theoretical basis for the selection, utilization and hybrid breeding of mung bean germplasm resources.

ABSTRACT The impact of low water availability on maize yield depends on the severity of the water deficit and the phenological stage of the crop. The objective of this study was to evaluate the variability of the water regime during flowering in white (GB) and yellow (GA) maize hybrids and its effects on grain yield. The study was conducted under field conditions in a pelic vertisol soil in Celaya, Guanajuato, Mexico. The drought condition of the crop was 75% of soil humidity with a soil water potential of -1.5 MPa. Hydraulic conductivity (Lp), water (Ψr) and osmotic (Ψs) potentials of the roots (during flowering phenophase), grain yield and water productivity were the evaluated variables. As results, significant variability of the water regime variables was obtained among the evaluated hybrids, resulting in variation of grain yield. The white-grain hybrids with the highest Lp were GB4 and GB5 and for yellow-grain GA2 and GA10, all exceeding 347.75 mg m-1 s-1 MPa-1. In some hybrids Ψr and Ψs, decreased to more than -1.85 and -2.80 MPa, respectively, showing positive responsiveness during flowering to the drought condition of the soil. There was positive and significant correlation between Lp x Yield, and highly significant negative correlation between Ψs x Yield. The highest yielding hybrids were GB4 (8000 kg ha-1) and GA2 (7800 kg ha-1). These hybrids will continue to be evaluated for other variables for validation and recommendation for drought conditions.

ABSTRACT Potato virus Y (PVY) is recognized as one of the most common and destructive pathogens seriously affecting potato producing areas worldwide. More recently PVYNTN and PVYN:O/N-Wi, have emerged as the main strains present in the PVY infected plants detected in Brazilian potato fields. In this study, samples of potato collected in south part of Minas Gerais - Brazil were first tested by DAS-ELISA and then by RT-PCR multiplex in order to discriminate the PVY strains. Afterward, part of them was tested by RT-qPCR to confirm and quantify the viruses in infected tissues. The sensitivity of the techniques for detecting PVY isolates present in the sampled locations was investigated, as well as the occurrence of mixed infections, aiming to understand the general epidemiological picture of this pathogen in potato producing fields. In the multiplex RT-PCR test, the samples with O and N serotypes were identified as infected with PVYNTN and PVYN:O/N-Wi strains. When tested by RT-PCR for amplification of PVYE, 41 samples (67,2%) were positive, having a characteristic electrophoretic profile for this recombinant strain, and 9 isolates were also observed with atypical patterns for recombinant PVYE. The best technique to detect mixed infection was RT-qPCR, with the concentration of PVYNTN being much higher than that of PVYN:O/N-Wi. These results show the importance of using the most suitable method for the diagnosis and surveying of PVY strains in crop fields and reveal, for the first time, the dissemination of PVYE recombinants to several Brazilian potato fields.

Abstract The Astragalus grahamianus (AG) Royle ex. Benth is traditionally used for the treatment of various human disorders. The current research work is aimed to explore the neuroprotective anti-Parkinson effects of various fractions of Astragalus grahamianus (A. grahamianus). Fine powder of Astragalus grahamianus was extracted with 70% methanol and then fractionated with various solvents on the basis of polarity. Standard protocols were used to investigate the bioactive constituents present in the various plant fractions. In-vitro antioxidant potential of various fractions was checked using diverse free radicals. In-vivo rats model was used to determined the neuroprotective effects of methanol fraction of A. grahamianus. The results revealed that various fractions of A. grahamianus contain flavonoids, cardiac glycosides, steroids, gums, terpenes, proteins, and carbohydrates except chloroform fraction lake the presence of steroids, cardiac glycosides, gums and saponins, aqueous fraction of steroids, terpenoids, gums and saponins, n-Hexane fraction steroids, carbohydrates, alkaloids, gums and flavonoids. The highest amount of total phenolic contents was found in AGME (32.67 ± 2.3 mg GAE / g). The AGME also showed enhanced free radicals cations potential against DPPH, ABTS and H2O2, respectively. The correlation between AOA (antioxidant activity) and TPC (total phenolic contents) revealed to be substantial. Relative R2 values for ABTS, H2O2, and DPPH activity are 0.9974, 0.9845, and 0.9678, respectively. The in-vivo neuroprotective activities showed significant results. Our findings highlight significant antioxidant, and neuroprotective possessions of AGME attributed to powerful bioactive compounds.

Abstract The article gives a geobotanical description and a floristic analysis of communities with the participation of the rare and relict species Alnus glutinosa in condition of Aktobe region. The aim of the study is to provide a geobotanical assessment of the current status of a rare, relict species of the Alnus glutinosa population, which was included in the Red Data Book of Kazakhstan. At present, the flora of the Aktobe region is not sufficiently studied. Conservation of the biodiversity of the Aktobe region flora is one of the most topical issues. In Aktobe region, due to the lack of grazing, felling of trees, using as fuel and the emergence of uncontrolled tourism and at the same time due to the lack of natural renewal of the area, these consequences lead to a quantitative reduction in the species. In this regard, it is necessary to study the species and organize protection and conservation measures. The results of the study showed that the plant Alnus glutinosa is rarely found in the flora of Kazakhstan and also the distribution areas are reduced. Of the three investigated points, plants from 24 families were identified. Plant communities of Alnus glutinosa are being studied for the first time in the Aktobe region. For the first time in the conditions of the Aktobe region, the habitat of black alder was discovered. The floral composition of plant communities of Alnus glutinosa grown in various ecological environments was revealed, the ratio of life forms and phytocenotic features were studied for the first time. In addition, alder felt mite and ground bug, damaging black alder, were identified from 3 studied populations. It has been established that the main reason for the spread of this pest is a very strong moistening of the ground on which sticky Alder grows. Results sequencing showed that the DNA sample under study belongs to the fungus Alternaria alternata.

Published: August 2024

Abstract In the last few years, there has been an increasing interest in solutions for sustainable agriculture to reduce negative impacts on the environment resulting from modern agricultural practices. The use of environmentally beneficial bacteria, like Pseudomonas, which can increase plant productivity by reducing growth time, is a promising opportunity for sustainable agriculture. Pseudomonas is a gram-negative bacterium genus, commonly present in soils, plants, and irrigation water. Pseudomonas has a wide range of metabolic routes that could benefit agriculture, such as nutrient uptake, pathogen suppression, heavy metal solubilization, drought tolerance, and high salt concentration tolerance. Pseudomonas may even be proposed as a potential tool for future agriculture on other planets, where the use of microorganisms would be essential for crop development in hostile and inhospitable environments. Hence, the present review discusses the potential use of Pseudomonas in sustainable agriculture on planet Earth and potentially on Mars, highlighting its role in plant growth enhancement and plant protection from pathogenic microorganisms.

Abstract The World Health Organization (WHO) declared an international state of emergency in order to contain the rapid spread of COVID-19. To ensure that there is adherence to preventive measures by the population aimed at controlling the pandemic in Alagoas, it is expected that knowledge, behavior and practices play an important role in preventing and controlling the disease. In this sense, it becomes relevant to understand the knowledge of the population about the disease. To evaluate the knowledge, behavior and practices of social media users during social isolation to prevent the transmission of the SARS-CoV-2 in the state of Alagoas, Northeast, Brazil. A probabilistic sample was carried out across the entire territory of the state of Alagoas with those who have access to a device that accesses the internet and a cross-sectional study was carried out using an online questionnaire applied to a convenience sample, recruited between August 2021 and July 2022 by snowball sampling. The questionnaire consisted of seven sessions, the first collecting data on the socioeconomic and sociodemographic profile of the participants, and the other sessions involving knowledge, attitudes and practices, including topics related to the vaccination that had to be administered at that time. High popular knowledge about signs and symptoms, means of transmission and risk groups. Low knowledge about seeking health services. Based on the results obtained, information from official channels became relevant to better teach the population in order to reduce the impact of COVID-19.

Published: August 2024

ABSTRACT Purpose: This research aims to measure the impacts of determining factors of organizational ambidexterity on academic performance in private higher education institutions (HEIs) in Brazil. Originality/value: This study investigates predictive, mediating, and moderating relationships in a model that has yet to be explored in the literature. Design/methodology/approach: This theoretical-empirical research uses questionnaires containing 172 Brazilian private HEIs and analyzes them through structural equation modeling. Findings: The results indicated that entrepreneurial orientation positively influences academic performance directly or is mediated by organizational ambidexterity. Learning orientation does not directly influence academic performance, but the result is significant when mediated by organizational ambidexterity. Although not substantial, market turbulence shows a medium moderation in the relationship between ambidexterity and performance. The indirect path between entrepreneurial orientation and academic performance mediated by organizational ambidexterity was stronger than the direct path without the mediation of ambidexterity. In conclusion, ambidexterity is presented as a relevant construct to mediate entrepreneurial orientation and learning orientation in the performance of private HEIs in Brazil under conditions of market pressure.
A gestão orgânica de conflitos desenvolvida em empreendimentos formados por mulheres da economia solidária: uma análise pós-colonialista sobre uma prática feminista de autogestão
Authors: Soares Maria de Nazaré Moraes , Rebouças Sílvia Maria Dias Pedro , Lázaro José Carlos
Published: August 2024

Resumo Esta pesquisa surge dos estudos das práticas de gestão de mulheres, de Martin (1993), contudo se articula no lugar da autogestão da Rede de Economia Solidária e Feminista (RESF). Por isso, foi desenvolvido, ao longo do texto, um novo construto para identificar algumas práticas que se performatizam na economia solidária (ES), nomeadas de práticas feministas de autogestão (Bauhardt, 2014; Faria, 2017; Vieta, 2015). O objetivo é analisar uma das ações observadas em campo: a gestão orgânica de conflitos. Os principais aportes teóricos para mediar a discussão partem da abordagem de Martin (1993), da perspectiva da racionalidade substantiva em Ramos (1989), dos estudos sobre conflitos nas organizações em Guerardi (2009) e Putnam (2010), bem como da visão pós-colonialista que adere ao contexto das mulheres na ES (Lugones, 2008; Mohanty, 2006). A coleta de dados se vale de entrevistas semiestruturadas com mulheres da RESF e da observação direta e indireta em campo, entre 2018 e 2021. A perspectiva adotada para a análise dos dados é a da história oral com base em análise crítica do discurso (Meihy, 2002; Wodak, 2004). Os resultados apontam para os seguintes achados: não ocultação do conflito nos processos de autogestão, conflito gerido de forma orgânica sob uma comunicação intensa e gestão do conflito como processo de aprendizagem que prioriza experiências e diferenças. Para as mulheres, o conflito não é demérito; em vez disso, ele é gerido de forma a fortalecer laços de reciprocidade entre os membros dos empreendimentos solidários.

Resumo A relação entre economia social e solidária (ESS) e gestão social (GS) no caso do colegiado territorial rural da baía da Ilha Grande (Colegiado BIG) abrange atividades de ensino, pesquisa e extensão. A questão de pesquisa é a influência da GS na ruptura dos ciclos de “inserção e desmantelamento” das políticas públicas de ESS (Silva, 2021). O objetivo é analisar a escalabilidade da ESS no contexto do Colegiado BIG, tendo como objetivos intermediários estabelecer referências para pensar as categorias teóricas da GS e qualificar um campo de relações entre ESS e GS. A hipótese é construir um pacto pela sustentabilidade do território baseado na disponibilidade de água, com contrapartida em pagamentos por serviços ambientais (PSA), configurando uma moeda social. O eixo teórico-metodológico é a discussão das categorias teóricas da GS, do campo do poder e da análise relacional. A metodologia foi a utilização da pesquisa de campo participativa, com as ferramentas da prospectiva. Os procedimentos metodológicos consistem em retrospectiva do marco legal das políticas ambiental e da influência dos movimentos sociais nas políticas de desenvolvimento territorial. A análise dos resultados comporta 4 sessões: variáveis-chave da gestão colegiada na BIG desde o desmantelamento das políticas do Ministério do Desenvolvimento Agrário (2000-2016); relações entre comunidades tradicionais e organizações de extensão universitária; cenários do pacto pela sustentabilidade do território com referência nos ODS; verificação na prática das categorias da GS. A resposta à questão de pesquisa está configurada no paradigma da gestão social em pagamentos por serviços ambientais.
El nuevo municipalismo y la gestión de lo común: la experiencia de la Red de Municipios Cooperativos (República Argentina, 2016-2022)
Authors: García Ariel Oscar , Tarsia Aldana García
Published: August 2024

Resumen El presente artículo tiene la finalidad de presentar una experiencia de generación de políticas públicas elaboradas en el intercambio entre burocracias locales y sector cooperativo bajo el precepto de generar una dinámica económica asociada al compre local cooperativo, en el que el crédito es una dimensión relevante para la generación y sostenimiento de fuentes de empleo locales y el fortalecimiento de la estructura económica municipal. El nuevo municipalismo como enfoque teórico permite la conceptualización de la Red de Municipios Cooperativos de la República Argentina como una herramienta de gobernanza comunitaria y de gestión urbana. A través de fuentes primarias (entrevistas semiestructuradas y observaciones de campo) y secundarias (bibliografía académica e informes oficiales), se recupera la historia de la Red de Municipios Cooperativos (desde 2016 a la actualidad) y se analizan sus limitaciones y potencialidades en cuanto al mejoramiento de la sostenibilidad de las experiencias asociativas que acceden al financiamiento para el compre local en el marco de la red. En cuanto a las conclusiones, se destaca la capacidad de las iniciativas a escala local de fortalecer las economías municipales de forma autónoma a las políticas públicas nacionales.
Trabajo decente en la economía solidaria de Cataluña
Authors: Pascual Jordi Estivill
Published: August 2024

Resumen El objetivo de este trabajo es presentar un panorama del trabajo decente en la economía solidaria de Cataluña. Para ello se empieza por señalar las ambigüedades de este concepto a la vez que sus éxitos internacionales. Se continúa poniendo de relieve sus dificultades al desarrollarse en el sistema hostil del capitalismo y la importancia de un tratamiento histórico, al que se dedica otro apartado, para entrar en un análisis cualitativo y otro cuantitativo de la realidad en Cataluña. Se finaliza planteando algunas conclusiones y retos de futuro que se le plantean. El conjunto del trabajo se apoya en la amplia bibliografía existente y los análisis cualitativos y cuantitativos, en particular utiliza dos instrumentos de la Red Catalana de la Economía Solidaria. Se trata de Palmo a Palmo (Pam a Pam) una mapificación territorial de iniciativas y del balance social que se realiza desde 2007. El resultado de estos análisis es que la economía solidaria, aunque ha crecido mucho y se ha diversificado en los últimos años, continúa siendo un movimiento minoritario, pero que reúne unas condiciones más cercanas a lo que puede denominarse el trabajo decente.
Derivation of the Schrödinger equation IV: Stochastic and the Langevin Equations for Quantum Mechanics
Authors: Silva Filho Olavo Leopoldino da , Ferreira Marcello
Published: August 2024

This is the fourth paper of a series devoted to mathematically derive the Schrödinger equation using stochastic constructs. We then show that Quantum Mechanics has a stochastic support by following two paths: we first present a stochastic derivation already known in the literature and show that it is equivalent to the characteristic function derivation, made by us in the first paper of this series. However, this approach does not furnish the true stochastic dynamics of the quantum mechanical system, but only an averaged one. We then present a new derivation of the Schrödinger equation based on Langevin equations that present all features of a true stochastic system. These two approaches then improve our understanding of Quantum Mechanics to encompass stochastic behavior.

Resumo O objetivo do estudo foi validar a metodologia da imunoquimioluminescência (CLIA) através da imunoabsorção enzimática (ELISA), determinando a concentração sérica de progesterona em vacas de leite e de corte, durante o ciclo estral. Foram empregadas 30 vacas multíparas não-prenhes (12 da raça Holandesa Preta e Branca e 18 Nelore). Vacas com corpo luteo foram escolhidas com vistas à sincronização do estro e da ovulação, mediante aplicação de 500 mcg de cloprostenol (im). Após a aplicação do luteolitico, os animais foram diariamente submetidos a exames de ultrasssonagrafia (US) ovariana para verificação da ovulação (=dia 01 do ciclo), bem como eram colhidas 02 amostras de sangue para a determinação da P4 pela CLIA e ELISA. As amostras eram centrifugadas para a obtenção do soro, e congeladas a -20 graus para posterior dosagem. Os valores de ELISA e CLIA foram comparados entre si mediante teste t pareado, regressão, ANOVA e coefficiente de determinação (R2), visando a verificação da sensibilidade e correspondência linear. A concentração de P4 originou perfis similares entre as duas metodologias; os perfis de P4 foram mais elevados em bovinos de corte, que nos de leite. A correspondência entre as metodologias resultou em elevado quociente de R2 nos perfis de P4. Concluiu-se que a CLIA pode ser empregada nas determinações hormonais da P4 serica bovina; a CLIA mostrou elevada correspondência linear com os valores da ELISA; a CLIA pode auxiliar as biotecnicas da reprodução nas determinações hormonais.

Abstract The aim was to evaluate the effect of butterfly pea inclusion on the fermentation dynamics, nutritional quality and aerobic stability of mixed elephant grass silages. Butterfly pea levels (0, 20, 40, 60 and 80% on a natural matter basis) were added to elephant grass silages. A completely randomized design was adopted, with 5 treatments and 3 replications, totaling 15 experimental silos, which were opened after 30 days of fermentation. The inclusion of butterfly pea in elephant grass silages resulted in a quadratic effect for permeability, density, maximum pH, final pH, time to reach maximum temperature and aerobic stability (P<0.05). Butterfly pea inclusion levels increased dry matter recovery, pH, dry matter, organic matter, ether extract, crude protein and total digestible nutrients (P<0.001) and reduced gas and effluent losses, mineral matter, neutral detergent fiber, acid detergent fiber, hemicellulose, cellulose, lignin and total carbohydrates (P<0.001). Inclusions of 40, 60 and 80% of butterfly pea provided temperature increases at 10, 20, 30 and 40 hours. The inclusion of butterfly pea with levels of up to 80% reduces fermentation losses, allows for a nutritional increase and increase in aerobic stability of silages.

Abstract This study aimed to calculate the temperature and humidity indexes (THIs) derived from extremely high air temperatures during the months of December 2021, January, and February 2022 in Rio Grande do Sul. The main goal was to characterize and regionalize potential impacts on dairy production. We used hourly measurements of temperature and relative humidity from 28 meteorological stations of the INMET/SIMAGRO/SEAPI network. These data cover ten ecoclimatic regions of the state. THI and Estimated Milk Loss (EML) were calculated, with the daily number of hours classified under each THI category during the trimester by municipality and region. The effects of region and month on THI and EML were evaluated through analysis of variance at a 5% significance level. Differences between means were compared using the Tukey HSD test (P<0.05). The probability of each daily hour having a THI in thermal discomfort (THI>70) was determined through analysis of variance for binomial variables by region, with the observed effect of time (P<0.05), and means were compared using the non-parametric Bonferroni test at 5%. To group these data, we applied the ScottKnott test. The Baixo Vale do Uruguai stood out in the trimester with the highest THI values, indicating thermal discomfort. Conversely, no heat stress was indicated in the Serra do Nordeste. In all regions, the most frequent daily classification of thermal discomfort ranged from attention to alert, with January being particularly significant. The highest EML estimates for most of the eight production levels were recorded in January. High estimates of productivity loss occurred in cows with higher milk production potential.
