A OCUPAÇÃO DA ZONA RURAL COM FINS URBANOS, O ORDENAMENTO TERRITORIAL PELO MUNICÍPIO E A CIDADE SUSTENTÁVEL
O presente trabalho, através do método de pesquisa bibliográfico, busca tecer reflexões sobre a ocupação da zona rural com fins urbanos e o ordenamento territorial pelo município a partir das funções socioambientais da propriedade e da cidade, e do direito à cidade sustentável, conforme diretrizes do Estatuto da Cidade. A Constituição Federal atribui ao Município o dever de promover o adequado ordenamento territorial e a execução da política urbana, devendo realizar o planejamento do seu território como um todo através do Plano Diretor, incluindo as atividades desenvolvidas na zona rural, visando implementar o direito à cidade sustentável
O processo orçamentário do Ministério da Fazenda sofre influência do modelo de orçamento incremental?
O artigo analisa o processo de elaboração do orçamento do Ministério da Fazenda no período de 2010 a 2018. A hipótese testada é que o orçamento o MF é incremental, elaborado através de ajustes marginais nos seus itens de despesa e de programação dos anos anteriores. Foram analisados os dados orçamentários dos Programas do MF obtidos do Sistema de Planejamento e Orçamento do Governo Federal – SIOP. Verificou-se que os programas do MF apresentam uma tendência de crescimento, sem grandes alterações no período. A conclusão foi que o orçamento do MF é uma repetição do orçamento anterior acrescido da variação de preços ocorrida no período e pequenos ajustes nas programações.27 páginasGestão PúblicaOrçamento e Finança
How does performing demanding activities influence prospective memory? A systematic review
This paper is the first systematic review on the role of ongoing task load in prospective remembering, which was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Forty articles published between 1995 and 2020 were included. They evaluated prospective memory (PM) performance (i.e., the ability to remember to execute a delayed intention) in adult samples aged between 19 and 50 years old when the PM cue appeared under cognitively demanding conditions.The results revealed that people are more likely to fail to remember to perform a delayed intention at the appropriate circumstances or time in the future when their cognitive resources are taxed by demanding ongoing activities. We conclude the review by highlighting that the degree of working memory and executive resources seems to account for some of the discrepant findings and by proposing directions for future research.- This project was founded by the Portuguese Foundation for Science and Technology (FCT, Portugal) with the grant BD/123421/2016 awarded to Patricia Matos and with thegrant PD/BD/105964/2014 awarded to Diana R.

Pollen Analysis of Food Pots Stored by Melipona subnitida Ducke (Hymenoptera: Apidae) in a Restinga area
The geographic distribution of Melipona subnitida covers the dry areas in the northeastern Brazil, where it plays an important role as pollinator of many wild plant species. In the current study, the botanical species this bee uses as pollen and nectar sources in a restinga area of the Maranhão State, Brazil, were identified by analyzing pollen grains present in their storage pots in the nests. Samples were collected from five colonies bimonthly, from April 2010 to February 2011. In all the samples, 58 pollen types were identified; the families Fabaceae (8) and Myrtaceae (5) had the largest number of pollen types. In the pollen pots, 52 pollen types were identified; Fabaceae, Melastomataceae, Myrtaceae and Dilleniaceae species were dominant. In honey samples, 50 pollen types were found, with a predominance of nectariferous and polliniferous plant species. Out of the total of pollen types from nectariferous plants identified in honey, 20 pollen types contributed to the honey composition. Humiria balsamifera occurred in high frequency and was predominant in October. Chrysobalanus icaco, Coccoloba sp., Cuphea tenella and Borreria verticillata were also important for honey composition. The occurrence of a high number of minor pollen types indicated that M. subnitida visits many species in the locality; however, it was possible to observe that its floral preferences are very similar to those from other Melipona species
Problematizações sobre distúrbios e dificuldades de aprendizagem na escola
This work aims to address issues related to problematizations referents to the
difficulties and learning disorders in the school, has as a source literary studies,
becoming a production of literature review. The study started from the need to
understand the challenges faced by teachers in the classroom day to day with
students who have difficulties learning, assimilating and socializing knowledge. Often
these children are “diagnosed” at home by parents or at school by their teachers and
colleagues, causing an even greater trauma in this early stage of learning. On the
other hand, if a correct assessment is not performed, the child ends up being labelled
negatively as slow and lazy, so the importance of the school guiding the parents to
look for specialized professionals as psychologists, psychopedagogues and
neuropediatricians for the diagnosis to be formalized and thus, to favor practices that
act on the learning problems encountered. We will use as a methodological resource
the research of publications carried out in the portals of BDTD-Brazilian Digital
Library of Theses and Dissertations, in the Institutional Electronic Repository UFPB
and ANPED, in the last 5 years. We support ourselves in the theoretical references of
Arroyo, Kirk, Nunes and Silveira, Rotta, Ohlweiler and Riesgo. In the analyses and
discussion we explored 9 articles that made reference to the theme being the main
questions for the execution of this work.Este trabalho tem como objetivo abordar questões relacionadas as problematizações
referentes as dificuldades e distúrbios de aprendizagem na escola, tem como fonte
estudos literários, se configurando numa produção de revisão de literatura. O estudo
partiu da necessidade de compreender os desafios enfrentados pelos professores
no dia a dia na sala de aula com alunos que possuem dificuldades em aprender,
assimilar e socializar o conhecimento. Muitas vezes essas crianças são
́ ́diagnosticadas`` em casa pelos pais ou na escola pelos seus professores e
colegas, ocasionando um trauma ainda maior nessa fase inicial de aprendizagem.
Por outro lado, se não for realizada uma avaliação correta, a criança acaba sendo
rotulada negativamente como lerda e preguiçosa, por isso a importância da escola
orientar os pais a procurar profissionais especializados como psicólogos,
psicopedagogos e neuropediatra para que o diagnóstico seja formalizado e assim,
favorecer as práticas que atuem sobre os problemas de aprendizagem encontrados.
Usaremos como recurso metodológico a pesquisa de publicações realizadas nos
portais do BDTD – Biblioteca Digital Brasileira de Teses e Dissertações, no
Repositório Eletrônico Institucional UFPB e ANPED, nos últimos 5 anos.
Respaldamo-nos no referencial teórico de Arroyo, Kirk, Nunes e Silveira, Rotta,
Ohlweiler e Riesgo, entre outros. Nas análises e discussão exploramos 9 artigos que

Inhibition of Plasmodium liver infection by Ivermectin
Copyright © 2017 Mendes et al. This is an open-access article distributed under the terms of the Creative Commons Attribution 4.0 International license.Avermectins are powerful endectocides with an established potential to reduce the incidence of vector-borne diseases. Here, we show that several avermectins inhibit the hepatic stage of Plasmodium infection in vitro Notably, ivermectin potently inhibits liver infection in vivo by impairing parasite development inside hepatocytes. This impairment has a clear impact on the ensuing blood stage parasitemia, reducing disease severity and enhancing host survival. Ivermectin has been proposed as a tool to control malaria transmission because of its effects on the mosquito vector. Our study extends the effect of ivermectin to the early stages of mammalian host infection and supports the inclusion of this multipurpose drug in malaria control strategies.A.M.M., P.M., and M.P. acknowledge the Fundação para a Ciência e Tecnologia, Portugal, for grants SFRH/BPD/80693/2011, SFRH/BD/71098/2010, and Investigador FCT (2013), respectively.

Pollen Analysis of the Post-Emergence Residue of Euglossa Bees (Apidae: Euglossini) Nesting in an Urban Fragment
Euglossini bees are considered pollinators of a wide variety of plants in the Neotropical region, but little is known about their floral preferences. In this study, we identified the botanical species used as pollen and nectar sources by three Euglossa species (Euglossa cordata, Euglossa townsendi, and Euglossa securigera) using pollen residue found in brood cells from trap nests installed in an urban fragment in São Luís, Maranhão, Brazil. In 14 analyzed Eg. cordata nests, 23 pollen types were observed, in 7 Eg. townsendi nests, 10 pollen types were observed, and in 1 nest of Eg. securigera, 6 morph types were identified. Solanum (Solanaceae), Zanthoxylum (Rutaceae), Mimosa pudica (Fabaceae), and Chamaecrista (Fabaceae) pollen types were common to all three bee species. Principal components analysis showed 83.04% variability on the first two axes, demonstrating substantial similarity among the samples. Solanum, Mimosa pudica, and Zanthoxylum were the principal components in the ranking. Larger diversity values (mean = 0.80) in some samples indicate that the species gathered resources in a heterogeneous manner; this resembles the findings of other studies of Euglossa. In general, the bees exhibited overlapping niches with regard to the most abundant pollens in the nests, but the females showed individual plasticity when gathering the floral resources
Analysis of Land Cover Distribution and Spatial Pattern of Landscape Fragmentation and Connectivity in the Taperoá and Upper Paraíba River Basins, Brazil
As bacias do alto curso do rio Paraíba e do Taperoá localizam-se na zona semiárida do Estado da Paraíba.
Grande parte da delimitação do semiárido possui bosques de Caatinga, que por suas condições bioclimáticas,
diversidade e endemismos, torna-se um bioma singular, estendendo-se por uma superfície de 844.453Km2
IBGE (2010). Diante do exposto, o objetivo deste trabalho foi analisar a distribuição do uso, cobertura do
solo, padrão espacial da fragmentação e conectividade da paisagem nas bacias do alto Paraíba e do Taperoá.
O mapeamento foi feito a partir de classificação GEOBIA de imagens MSI do satélite Sentinel 2, com o uso
do software GUIDOS. Os resultados apontam a maior presença de caatinga e maior conectividade no sul e
noroeste na bacia do alto Paraíba e no sudoeste da bacia do TaperoáLa cuenca de alto curso de río Paraíba y del Taperoá ubican-se en la zona semiárida del Estado de Paraíba.
