POLĂTICAS PĂBLICAS E (RE)PRODUĂĂO SUSTENTĂVEL DO ESPAĂO URBANO: âPROGRAMA RECIFE SEM PALAFITASâ â SEUS BENEFĂCIOS E SUA NATUREZA SOCIAL (Public policies and sustainable (re)production of the urban space: the âRecife without stiltsâ program...)
Este artigo analisa alguns dos benefĂcios e a natureza social do âPrograma Recife sem Palafitasâ, explicando em que medida as populaçÔes realocadas tĂȘm tido suas necessidades reais atendidas em sua complexidade e totalidade, extrapolando a valorização puramente econĂŽmica do espaço urbano. A metodologia deste escrito fundamenta-se em pesquisas bibliogrĂĄfica, cartogrĂĄfica e documental sobre polĂticas pĂșblicas, contextualizando-as na histĂłria dos programas de remoção de habitação de interesse social; bem como em trabalho de campo realizado nos novos conjuntos habitacionais e nas ĂĄreas desocupadas. Observou-se que, no passado, as açÔes governamentais aconteciam em contexto de pouca ou nenhuma compreensĂŁo da realidade das famĂlias atingidas, expulsando-as das ĂĄreas mais valorizadas da cidade; e que, a partir de 2003, a Prefeitura do Recife, administrada pelo Partido dos Trabalhadores, tem apresentado condiçÔes de cumprir com o seu papel de provedora de polĂticas pĂșblicas de interesse social, fazendo reduzir as desigualdades territoriais.

ABSTRACT
This paper analyses the benefits and social nature of the âRecife without Stiltsâ Program, explaining how the relocated populations have continued to benefit from this program; and taking into account the complexity and totality they have been able to maintain. This examination of urban dynamics goes beyond a merely economic valorization of the urban space. The methodology of this academic project is based on literature, maps and documents surrounding public policies, considering the history of policies for the removal of sub-standard housing, and what lies behind these policies. The field work encompasses the new housing and the areas that have been evacuated. In the past, urban management was not able to comprehend nor consider the reality of poor families in its policies. Nowadays, however, the urban focus of the Workersâ Party administration, principally since 2003, has tried to intervene in a different way. Public housing policies are applied to promote the reduction of territorial inequalities.

Residue from the production of Pochonia chlamydosporia in the development of lettuce seedlings and plants
O objetivo deste trabalho foi avaliar o efeito de subproduto do processo de produção de Pochonia chlamydosporia var. chlamydosporia no desenvolvimento de mudas e plantas de alface. Esse subproduto, um resĂduo constituĂdo de arroz que continha propĂĄgulos do fungo, foi adicionado em diferentes concentraçÔes (0, 2 e 4% volume de resĂduo:volume de substrato) a trĂȘs tipos de substratos para mudas (formulado, comercial e fibra de coco). Sementes de alface foram semeadas em bandejas de isopor que continham os diferentes substratos enriquecidos com o resĂduo. As mudas de alface foram transplantadas para vasos com o substrato solo e areia na proporção 1:1 (v:v), 28 dias apĂłs a semeadura. Todos os tipos de substratos e doses do resĂduo apresentaram interação significativa para todas as variĂĄveis relacionadas ao desenvolvimento das mudas e das plantas de alface. O maior desenvolvimento das mudas ocorreu na testemunha (sem o resĂduo) dos substratos. Entretanto, apĂłs o transplantio das mudas para os vasos, as doses de resĂduo atĂ© 4 e 2% v:v â nos substratos formulado e comercial, respectivamente â foram as que promoveram o maior desenvolvimento das plantas. A utilização de atĂ© 2% v:v do resĂduo nos substratos formulado e comercial Ă© viĂĄvel e nĂŁo prejudica o desenvolvimento de plantas de alface.The objective of this work was to evaluate the effect of a byâproduct of the production process of Pochonia chlamydosporia var. chlamydosporia in the development of lettuce seedlings and plants. This byâproduct, a residue made up of rice containing propagules of the fungus, was added at different concentrations (0, 2, and 4% volume of residue:volume of substrate) to three types of substrates for seedlings (formulated, commercial, and coconut fiber). Lettuce seeds were sown in polystyrene trays containing the different substrates enriched with the residue. The lettuce seedlings were transplanted into pots containing soil and sand substrate at the proportion 1:1 (v:v), 28 days after sowing. All types of substrates and residue levels showed a significant interaction for all variables related to the development of lettuce seedlings and plants. The highest development of seedlings occurred in the control treatment (no residue) of the substrates. However, after transplanting the seedlings into the pots, the residue levels of up to 4 and 2% v:v â in the formulated and commercial substrates, respectively â promoted the highest plant growth. The use of up to 2% v:v of the residue on the formulated and commercial substrates is viable and does not affect the development of lettuce plants

Portal de Acesso Ă s InformaçÔes das AçÔes das Universidades Federais em Resposta Ă Pandemia de Covid-19: uma anĂĄlise do perĂodo pandĂȘmico atĂ© a transição para uma pĂłs-pandemia
During the pandemic, a new organization of the academic activities of the Federal Universities was necessary to undertake internal and external actions to face Covid-19. To share the actions carried out, the Ministry of Education (MEC) developed two information portals on the numbers of Covid-19 and the actions developed for basic and higher education. One of these portals is the "Coronavirus Panel â Monitoring the Federal Network" which brings together a set of information regarding the actions taken by educational institutions from the beginning of the pandemic to the current moment of transition to a post-pandemic. Using a method of analyzing quantitative and qualitative data, we seek to discuss and correlate data from Covid-19 cases and their peaks with actions involving teaching, prevention and support to the academic community. As a result, some panels of the portal and the analysis of data from the actions are presented in a correlated way, allowing the sharing of strategies and the historical understanding of which actions were used in facing the pandemic and in the transition from a post-pandemic.Durante a pandemia, foi necessĂĄria uma nova organização das atividades acadĂȘmicas das Universidades Federais para empreender açÔes internas e externas de enfrentamento Ă Covid-19. Para compartilhar as açÔes realizadas, o MinistĂ©rio da Educação (MEC) desenvolveu dois portais de informação sobre os nĂșmeros da Covid-19 e sobrea as açÔes desenvolvidas para a educação bĂĄsica e superior. Um desses portais Ă© o âPainel CoronavĂrus â Monitoramento da Rede Federalâ, que reĂșne um conjunto de informaçÔes referente Ă s açÔes realizadas pelas instituiçÔes de ensino desde o inĂcio da pandemia atĂ© o momento atual de transição para uma pĂłs-pandemia. Utilizando um mĂ©todo de anĂĄlise de dados quantitativos e qualitativos, buscou-se discorrer sobre os dados de casos de Covid-19 e seus picos como as açÔes envolvendo modalidade de ensino, prevenção e apoio Ă comunidade acadĂȘmica. Como resultado, sĂŁo apresentados de forma correlacionada alguns painĂ©is do portal e a anĂĄlise dos dados das açÔes, permitindo compartilhar as estratĂ©gias e a compreensĂŁo histĂłrica de quais açÔes foram utilizadas no enfrentamento da pandemia e na transição de uma pĂłs-pandemia
Estrutura FitossociolĂłgica de um Cerrado Sensu Stricto, em Gurupi, Tocantins
Cerrado sensu stricto is a savannah phytophysiognomy with great floristic diversity and occupies approximately 70% of the Cerrado biome but undergoes rapid conversion to areas of anthropic use. Therefore, the objective was to analyze the phytosociological structure of a cerrado sensu stricto in Gurupi, Tocantins. In five plots of 20x50m were sampled individuals with circumference at breast height â„ 10 cm. A total of 906 individuals were found, distributed in 102 species, 42 families and 78 genera. The diversity index (H ') was 3.70 and the equability (J') was 0.80. The family with the highest importance value index (IVI) was Myrtaceae. The species Myrcia fallax obtained the largest number of individuals and IVI (23.1%). In relative dominance, Protium heptaphyllum (12.2%) and Tapirira guianensis (7.1%) stood out. The other species found presented values lower than (5.7%). The indices obtained in this study indicate the existence of a high floristic diversity.O cerrado sensu stricto Ă© uma fitofisionomia savĂąnica com grande diversidade florĂstica e que ocupa, aproximadamente, 70% do bioma Cerrado, porĂ©m, sofre uma rĂĄpida conversĂŁo para ĂĄreas de uso antrĂłpico. Diante disso, objetivou-se analisar a estrutura fitossociolĂłgica de um cerrado sensu stricto em Gurupi, Tocantins. Em cinco parcelas de 20x50m foram amostrados os indivĂduos com circunferĂȘncia a altura do peito â„ 10 cm. Foram encontrados 906 indivĂduos, distribuĂdos em 102 espĂ©cies, 42 famĂlias e 78 gĂȘneros. O Ăndice de diversidade (Hâ) foi de 3,70 e a equabilidade (Jâ) de 0,80. A famĂlia com o maior Ăndice de valor de importĂąncia (IVI) foi Myrtaceae. A espĂ©cieMyrcia fallax obteve o maior nĂșmero de indivĂduos e de IVI (23,1%). Na dominĂąncia relativa se destacaram Protium heptaphyllum (12,2%) e Tapirira guianensis (7,1%). As demais espĂ©cies encontradas apresentaram valores inferiores Ă (5,7%). Os Ăndices obtidos neste estudo indicam a existĂȘncia de uma alta diversidade florĂstica
Mineralogy, chemistry and stability of silt-size aggregates of soils from the Southeast Region of Brazil
Com o objetivo de avaliar a relação da composição mineralĂłgica e quĂmica do solo com a estabilidade de agregados do tamanho de silte, foram realizados estudos utilizando-se amostras de horizontes A e B de diversos solos da RegiĂŁo Sudeste do Brasil. Amostras de TFSA foram dispersas a 12.000 rpm por 20 minutos e a fração silte foi separada por esgotamento da fração argila, constituindo-se na fração denominada pseudo-silte, a qual foi sonificada, separando-se a fração argila desagregada (por sifonamento) da fração silte propriamente dita. Estudos de correlação mostraram que as composiçÔes mineralĂłgica e quĂmica dos solos tĂȘm efeito marcante na dispersĂŁo de argila, com reflexos na fração silte. Maiores teores de gibbsita refletem em maior estabilidade dos agregados do tamanho de silte ao passo que a caulinita proporciona efeito inverso. As formas de Al determinadas na fração pseudo-silte estĂŁo associadas Ă maior dificuldade de dispersĂŁo da fração argila dos solos.The objective of this work was to evaluate the relationship of soil mineralogical and chemical composition with stability of silt-size aggregates. The studies were carried out using samples of A and B horizons of some soils from the Southeast Region of Brazil. Fine-earth samples were dispersed at 12,000 rpm during 20 minutes and the silt fraction was separated through clay fraction drain, constituting the fraction named pseudo-silt, which was sonificated, separating the desegregated clay fraction (by sonication) from the properly named silt fraction. Correlation analyses showed that the soil mineralogical and chemical compositions have marked influence upon clay dispersion, with reflections on the silt fraction. Higher amounts of gibbsite reflect in higher stability of silt-size aggregates, while the kaolinite promotes inverse effect. The Al forms determined on the pseudo-silt fraction are associated with higher difficult of dispersion of clay fraction of soils
Metastases of Melanoma to Head and Neck Mucosa: A Report of Short Series
Objectives Metastasis of melanoma to the head and neck mucosa is a very unusual condition. The aim of this study was to report four cases of patients with metastatic melanoma in the head and neck mucosa treated at a single institution. Methods Clinical data were obtained from the medical records. All cases were histologically reviewed to confirm the diagnosis, and immunohistochemical reactions were performed in the cases submitted to biopsy. Results All patients were males and the mean age was 40.5 years old. The sites of the metastatic tumors were gingival mucosa, floor of the mouth, oropharynx, and larynx. Two tumors appeared as submucosal nodules with normal color; one lesion was a blackish nodular lesion, and one was shown to be an ulcerated lesion. The size of tumors ranged from 2.0 to 4.0 cm. All patients had developed systemic disease at time of diagnosis of metastatic tumor in the head and neck mucosa. Survival rates ranged from 2 to 19 months after the diagnosis of the metastatic mucosal melanoma in the head and neck region. Conclusion Although rare, patients with melanoma must be closely and regularly followed up, with careful routine examination of head and neck, because metastatic tumors in this region seem to be part of a lethal widespread metastatic disease
