A new species of the wasp genus Trypoxylon from southern Brazil, with notes on the systematics of Pisoxylon (Hymenoptera, Crabronidae)
A new species of Trypoxylon is described from females and males collected in trap-nests and Malaise traps disposed in sites of Atlantic forest in southern Brazil (Paraná and São Paulo states). Trypoxylon basirufum sp. nov. is structurally very similar to Pisoxylon roosevelti Antropov, differing in details of the color pattern, clypeal apex, male antenna and propleura. In an ongoing molecular phylogenetic study of the genus Trypoxylon, T. basirufum sp. nov. did not group with Pisoxylon amenkei Antropov, a species very close morphologically to P. xanthosoma Menke, the type species of Pisoxylon. Based on these results, the scope of the Neotropical wasp genus Pisoxylon Menke is changed to include only the type species and P. amenkei, and consequently Pisoxylon roosevelti is transferred to Trypoxylon s. str
THE MEANING OF THE ORGANIC CERTIFICATION SEAL FOR THE CONSUMER: A CLUSTER ANALYSIS
Academia has been analyzing organic certification labels for at least 10 years, with emphasis on their importance and level of knowledge. However, little has been written about the associations and meanings they have for consumers. This article aims to study this meaning through a quantitative research, survey type, with 388 respondents. The data were analyzed through a cluster analysis which revealed the existence of three customer groups, according to the meaning assigned to the labels. The three segments were called “Greeners”, “GMO-Freers” and “Don’t Carers”. The first group, the “Greeners”, is the largest (46.6%), and brings greater association with the meanings “sustainable agriculture” and “environmentally friendly” and is associated with older people. The second, the “GMO-Freers”, presents closer association with the meaning “It does not make use of genetically modified/transgenic seeds” and is related to people who have already done post-graduation courses (24.7% of respondents). Finally, the third, “Don’t Carers”, (28.7%), shows lower association to the label’s meanings in general, and is also more concentrated in an elite group of consumers. The research comes to the conclusion that the label’s meanings may change according to different consumer profiles. On theoretical grounds the present study fills a gap in the literature in a way that it deepens a first analysis of the label’s meaning, by reaching a second level of consumer attributions, and revealing the need for understanding this meaning among different groups. Based on the consumer behavior model presented by Kotler and Keller (2012), it is possible to show how consumers’ psychological aspects can be influenced by social characteristics in the way the groups perceive organic labels. The practical contributions to manufacturers and certifying agencies of organic products are also discusse
Comparative Analysis Between Native and Hybrid Mobile Applications
With the growth of technology in the mobile area, the app market has been bringing solutions to many problems and making life easier for many people, whether in the business, technology, administrative and many others. It is necessary to understand that to build an app, there are many technologies for different purposes, and developers need to know which one is best applied in every situation. Therefore, the objective of this research is to bring an analysis about the native and hybrid development, showing its main features and information regarding the usability and functionality of two existing applications, which were built within the standards of each tool, based on two features of ISO / IEC 25010: 2011 regarding Software Product Quality. An exploratory research was conducted to bring comparative data regarding applications, and based on the results obtained, it was observed that it is possible to develop similar applications in interface, quality and functionality, even if they are built with different technologies. As a result, native technology is often used to build more robust functionality-based applications that follow the interface standard of each platform, and hybrids are a lower-cost alternative, as well as fact that its source code is fully reusable for use on other platforms
Impact of climate changes in the suitable areas for Coffea arabica L. production in Mozambique: Agroforestry as an alternative management system to strengthen crop sustainability
Climate changes (CC) are a main global phenomenon, with a worldwide impact on natural and agricultural
ecosystems. The objective of this study was to analyse the potential impact of future CC on the suitability of areas
for rainfed coffee growth, both at the Mozambique national scale and in the Gorongosa Mountain, under
Agroforestry (AFS) and Full Sun (FS) management systems. The latter study site is part of the Gorongosa National
Park (PNG), one of the most biodiverse places and an outstanding case of successful ecosystem restoration,
including the rainforest from Gorongosa Mountain. Additionally, coffee cultivation in PNG under AFS is part of a
strategy to strengthen the socio-economic sustainability of the local population, and the recovery of biodiversity
in a degraded tropical rainforest ecosystem. Future climate assessments were elaborated through bioclimatic and
biophysical variables (Elevation), with Coffea arabica L. being modeled under the current conditions and four
global climate models (GCMs) using four Shared Socio-economic Pathways (SSPs). Isothermality, annual precipitation,
and altitude were the most important variables influencing suitable areas in Mozambique. The
analysis revealed that currently suitable areas where C. arabica is grown in Mozambique will be negatively
affected under future scenarios (SSP126 to SSP585) in both systems (AFS and FS), although with clear worst
impacts for FS. Under AFS, suitable areas will be reduced between about half and two-thirds by 2041–2060, and
up to 91% by 2081–2100 (depending on scenarios) at the whole country level. Additionally, in Gorongosa
Mountain, almost all scenarios point to a 30% reduction of the suitable area by 2041–2060, reaching 50% by
2081–2100, both in SSP126 and SSP245 scenarios. In sharp contrast, at the whole country level, the FS system is projected to be unsuitable for most of Mozambique, with area losses close to or above two-thirds already in
2021–2040, and greater than 80% by 2061–2080. Under this system, the projections were even more dramatic,
pointing to a total absence of adequate areas at Gorongosa Mountain already by 2021–2040. Overall, our study
provides clear evidence that the implementation of AFS greatly reduces CC deleterious impacts, being crucial to
guarantee the sustainability of the coffee crop in the near future.info:eu-repo/semantics/publishedVersio

Estigma Social e saúde de mulheres com deficiência: um diálogo acerca da iniquidade
Este trabalho descreve o acesso à saúde por mulheres com deficiência (McD) à luz do conceito de estigma de Goffman1, a partir da Pesquisa Nacional de Saúde (PNS). O perfil da morbimortalidade e do acesso à saúde são impactados pelas desigualdades de gênero, sob o aspecto dos atributos biológicos e culturais, bem como os agravos à saúde decorrentes da associação entre estereótipos de gênero e estigmas específicos, e acabam por comprometer o exercício da cidadania, sobretudo relacionado ao direito à saúde
EFICÁCIA CLÍNICA DO LASER ACUPUNTURAL NO TRATAMENTO DA DESORDEM TEMPOROMANDIBULAR
A disfunção temporomandibular (DTM) é a condição mais frequente de dor orofacial crônica. A DTM é caracterizada pela a presença de sinais e sintomas na região orofacial. A acupuntura e Terapia a laser de baixa intensidade (TLBI) vêm sendo empregadas no tratamento da DTM. A acupuntura consiste na inserção de agulhas em acupontos específicos do corpo para promover efeitos terapêuticos. A TLBI é uma modalidade de tratamento não invasiva, que vem sendo utilizada com frequência na prática clínica para o tratamento das DTM. Diante do exposto, o objetivo deste estudo foi realizar revisão de literatura, acerca da eficácia clinica do laser acupuntural em pacientes com a DTM. O emprego do laseracupuntural no tratamento das DTM favorece o controle antálgico, miorrelaxante e anti-inflamatório, no entanto, são necessárias novas pesquisas acerca do tema para determinar a eficácia do laser acupuntural em longo prazo para o tratamento de desordens temporomandibulares

Monitoria de patologia nos tempos de pandemia: um relato de experiência / Pathology monitoring in times of pandemic: an experience report
Introdução: A Patologia Humana é uma disciplina teórico-prática que estuda os mecanismos de desenvolvimento das doenças. Na área da medicina, sua importância justifica-se pela possibilidade de realizar diagnósticos de diversas doenças a partir da comparação entre tecidos saudáveis e doentes. Nesse contexto, ressalta-se o desafio de auxiliar no ensino de uma disciplina teórico-prática durante a pandemia de COVID-19. Objetivos: Relatar as experiências da monitoria virtual no ensino da disciplina de Patologia. Metodologia: Para auxiliar no ensino do componente de Patologia foram desenvolvidos objetivos de aprendizagem semanais e roteiros com questões. A cada semana procuramos utilizar uma estratégia diferente de ensino, onde a gameficação é uma ferramenta bastante utilizada. Em alguns objetivos foram elaborados casos clínicos, jogos e quizzes intencionando-se maior fixação do conteúdo, interatividade, engajamento e motivação por parte dos discentes nesse semestre atípico. Alternando com essa ferramenta, utilizamos o site www.kahoot.it, o qual possui um quizz de perguntas e respostas que faz um ranking de acordo com o índice de acertos e tempo de resposta, estimulando uma competição saudável entre os participantes. Resultados: Após a utilização da estratégia de gameficação, observou-se maior estimulação no estudo prévio, maior interatividade dos alunos durante as monitorias e consequentemente maior desempenho dos mesmos nas dinâmicas propostas nas monitorias e atividade avaliativas da disciplina. Além disso, a monitoria propiciou à equipe de monitores a oportunidade aprender, explorar novas ferramentas e auxiliar os professores nesse mundo virtual. Conclusões: Observou-se, portanto, que mesmo à distância e utilizando ferramentas virtuais não habituais, a monitoria foi efetiva e cumpriu seu objetivo de auxiliar no aprendizado dos discentes, dar suporte ao docente e aproximar a teoria da prática
Effect of rice grain (Oryza sativa L.) enrichment with selenium on foliar leaf gas exchanges and accumulation of nutrients
grant number 101-030671An agronomic itinerary for Se biofortification of two rice cultivars (Ariete and Ceres) through foliar fertilization with sodium selenate and sodium selenite with different concentrations (25, 50, 75 and 100 g Se.ha−1), was implemented in experimental fields. The selenium toxicity threshold was not exceeded, as shown by the eco-physiological data obtained through leaf gas exchanges. The highest Se enrichment in paddy grains was obtained with selenite for both cultivars, especially at the highest doses, i.e., 75 and 100 g Se.ha−1, with approximately a 5.0-fold increase compared with control values. In paddy grains, Zn was the most affected element by the treatments with Se with decreases up to 54%. When comparing the losses between rough and polished grains regardless of the cultivars, Se species and concentrations, it was observed that only Cu, Mg and Zn exhibited losses 70%. The loss of Se is more pronounced in Ceres cultivar than in Ariete but rarely exceeds 50%. The analysis by µ-EDXRF showed that, in Ariete cultivar, Se is mostly homogeneously distributed in the grain regardless of any treatments, while in Ceres cultivar, the Se distribution seems to favor accumulation in the periphery, perhaps in the bran.publishersversionpublishe
