    This is a study on public politics of inclusion of students with special educational needs in higher education, trying to understand its advances and difficulties, therefore, nowadays, this theme has been debated in higher education and has provoked changes of paradigms in higher superior institutions. Initially, it describes the trajectory of higher education in Brazil, its structure and the form of access. It also mentions historical journey of Special Education, from segregation to current attempts of inclusion of students with special educational needs in regular system of education. It presents the legal aspects of inclusion. The legislation constitutes a politics action of access and democratization of higher education and it must be in accord with constitutional principles in warranting rights of people with special needs. However, it is not enough to assure this access and the permanence of these students in the university. The main goal of this research is to identify public politics of inclusion and permanence of students with special educational needs at UEPA. To reach our goal, we applied a qualitative research using interviews with students, professors and technician from UEPA and, after that, the accomplishment of analysis of data according to student, professor and technician vision involved in this process was adopted. The result of this study evidenced the University of State of Pará, in its experience on this process, has gotten great conquests and, still, discloses what it must have to be done, according to the vision of participants in this process.Este é um estudo sobre as políticas públicas de inclusão de alunos com necessidades educacionais especiais no ensino superior, buscando compreender seus avanços e dificuldades, pois nos últimos anos a discussão sobre essa temática chegou ao ensino superior e gerou mudanças de paradigmas nas instituições de ensino superior. Inicialmente, relata a trajetória do ensino superior no Brasil, sua estrutura e a forma de acesso a ele. Mostra, também, o percurso histórico da Educação Especial, da segregação às tentativas atuais de inclusão de alunos especiais na rede regular de ensino. Apresenta os aspectos legais da inclusão. A legislação constitui uma ação política de acesso e democratização do ensino superior e deve estar em consonância com os princípios constitucionais na garantia dos direitos das pessoas com necessidades especiais. Porém, não é suficiente para assegurar esse acesso e, consequentemente, a permanência desses alunos na universidade. O objetivo geral da presente dissertação tem por escopo identificar as políticas públicas de inclusão e permanência de alunos com NEE’s na UEPA. Para alcançar o objetivo proposto, foi adotada a pesquisa qualitativa por meio de entrevistas com discentes, docentes e técnicos da UEPA e, em seguida, realização de análise da visão dos discentes, docentes e técnicos envolvidos nesse processo. O resultado do estudo evidenciou que a UEPA, em sua experiência nesse processo, obteve grandes conquistas e, ainda, revela o que há a ser feito, conforme a visão dos sujeitos participantes desse processo

    http://dx.doi.org/10.5902/1980509818456 The quality of seedlings produced at forest nurseries is related to several factors, including irrigation and the used substrate. Both have as their purposes the production of quality seedlings in a short time period, but over-irrigation can negatively affect the substrate nutrient content. This work aimed to evaluate the chemical characteristics dynamics of a forest substrate subjected to successive irrigation at sub-irrigation tanks in two plastic tubes sizes. To this end, plastic tubes of 110 and 300 cm³ were placed, containing forest substrate without the presence of new seedlings at two sub-irrigation tanks with recirculation, one for each tube size, built at Universidade Federal de Lavras. It was set up completely randomized design with two replications, being the treatment levels 0,6, 12, 18, 24 and 30 irrigations, five per day. The substrate chemical characteristics were evaluated: pH, phosphorus, potassium, iron, zinc, manganese, copper, calcium, magnesium, aluminum, boron, sulfur, effective CEC, organic matter and electrical conductivity. Additionally, before the irrigations counted as treatment, water samples were taken to check for possible changes in the quality of irrigation recycled water after successive irrigations. The sub-irrigations provided only changes in the potassium concentration in the substrate in both tubes, and most of the chemical characteristics assessed on the substrate were unchanged as a sub-irrigation function.http://dx.doi.org/10.5902/1980509818456A Qualidade das Mudas Florestais produzidas em viveiros ESTÁ relacionada a Fatores Diversos, Entre enguias um Irrigação EO Utilizado pelo substrato.

    Modification in Webster technique for lower lip reconstruction, using bilateral nasolabial flaps to improve reconstruction of vermilion

    Get PDF
    INTRODUCTION: Many authors consider the Bernard technique modified by Webster the first choice for total lower lip reconstruction. This technique preserves skin folds and anatomical landmarks on the face, and interferes minimally with the tactile sensibility of the reconstructed lip, resulting in satisfying cosmetic and functional outcomes. Despite agreeing with the principles of the Webster technique, a modification is proposed to improve reconstruction of vermilion, by using bilateral nasolabial flaps associated with the original advancement flaps. METHODS: We report five surgical cases carried out between 2003 and 2008, and discussion of results. RESULTS: Dissection need to advance flaps in Bernard-Webster technique does not make nasolabial flaps unviable, and they can be rotated properly to add volume and skin to the reconstructed vermilion. CONCLUSION: Proposed modification of Bernard-Webster technique does not increase risk or damage compared with classic technique, and it maintains the same reconstructive capabilities or even enhances it

    Introduction: The nipple-areola complex (NAC) plays an important role both in breastfeeding and sexual lives of the patients. Because of this, we must mention possible complications of reduction mammoplasty, such change or even loss of sensitivity of the NAC. Method: This was a prospective, randomized, controlled, double-blind study to evaluate the relationship between the sensitivity of the NAC after reduction mammoplasty with dermal release and the resected volume of breast tissue. This study was conducted between August 2013 and August 2015 at the Hospital das Clínicas of the Federal University of Pernambuco (HC-UFPE), in Recife City, Brazil. Results: The study involved 39 patients. The mean age and body mass index (BMI) of the patients were 31.7 years and 25.5 kg/m2, respectively. None of the patients was a smoker. The complication rate was 41%, including 7 cases of non-aesthetic scars, 6 cases of hematoma (bruises), and 4 cases of dehiscence. No patient had pain or NAC necrosis, and all the patients expressed being satisfied with the final surgical result. No statistically significant differences were found between the patients of the experimental and control groups, both in the group with resection of up to 300 g and those with resection >300 g. Conclusions: The maneuver of dermic release did not result in any differences in the sensitivity of the NAC, regardless of the quantity of resected breast tissue

    Twenty-four female canine subjects were submitted to ovariohysterectomies through laparoscopic surgical procedures. The surgical procedures were performed under general anesthesia with the animals in dorsal recumbency. The abdominal cavity was accessed through a punction with a Veress needle and was inflated with CO2. The animal was then placed in Trendelemburg position and four trocars were inserted in different regions of the abdominal wall. Following uterus identification, blood vessels were isolated and clipped with metallic devices. The body of the uterus was cut cranial to the cervix. The ovarian bursa was exposed and the suspensor ligament was fixed with a nipper. The suspensor ligament was clipped previously to its section. The ovarian arterial-venous complex was clipped and cut with the mesovarium ligament. The round ligament and the mesometrium were cut with a scissors and cauterized. The uterus and both ovaries were removed from the abdominal cavity trough one of the incisions. The most important intra-operatory event was the presence of hemorrhage with one death and one conversion to celiotomy. In the majority of the animals the hemorrhage was controlled with the placement of clips and/or cauterization. The laparoscopic surgery showed to be a suitable technique to perform ovariohysterectomy in canine females.Neste estudo, foram realizadas ovário-histerectomias laparoscópicas em 24 caninos. Os procedimentos cirúrgicos foram realizados sob anestesia geral, com os animais em decúbito dorsal. A cavidade abdominal foi puncionada com a agulha de Veress e foi insuflada com CO2. Os animais foram então colocados em posição de Trendelenburg, e quatro trocartes foram introduzidos em diferentes regiões da parede abdominal. Após a identificação do útero, os vasos uterinos foram isolados e ligados com dois clipes de titânio. O corpo do útero foi seccionado cranialmente à cérvix. A bursa ovariana foi exposta, e o ligamento suspensor foi apreendido com uma pinça. Procedeu-se à aplicação de um clipe neste ligamento previamente a sua secção. O complexo arteriovenoso ovariano foi ligado com um clipe e depois foi seccionado em conjunto com o mesovário. O ligamento redondo e o mesométrio foram seccionados com tesoura e cauterização monopolar. O útero e ambos os ovários foram retirados em bloco da cavidade por uma das incisões existentes. A principal complicação transoperatória foi a ocorrência de hemorragia, que ocasionou um óbito e uma conversão para cirurgia aberta. Na maioria dos animais, esta complicação foi adequadamente controlada pela aplicação de clipes e/ou utilização de cauterização monopolar. A realização de ovário-histerectomia em caninos por cirurgia laparoscópica demonstrou ser viável, e a técnica descrita para este procedimento mostrou-se adequada

    The objective of this work is to describe, through the literature review, or the use of remote sensors integrated to unmanned vehicles (UAV). The types of sensors and their operation are also described in addition to the processing methods and applications in forestry and protection against forest fires. The UAV was used for military activities, mainly for monitoring areas of difficult access, for human use. With the technological development of vehicles equipped with the Global Satellite Navigation System (GNSS) and minimization of sensors made possible to capture electromagnetic electrical energy reflected and transmitted by targets on the surface, being converted into traffic signals so that they can be stored or transmitted in real time. The data captured by the sensors are processed to be used in the process of using information from objects observed on the earth's surface to be used in the management of forest resources.O objetivo deste trabalho é descrever, através de revisão da literatura, o uso dos sensores remotos integrados aos Veículos Aéreos Não tripulados (VANT). Os tipos sensores e seu funcionamento também são apresentados além dos métodos de processamento e aplicações na silvicultura e na proteção contra incêndios florestais. O VANT foi utilizado inicialmente em atividades militares, principalmente para atender monitoramento de áreas de difícil acesso, consideradas inósptas para o ser humano.  Com o desenvolvimento tecnológico dos veículos equipados com Sistema Globais de Navegação por Satélite (GNSS) e minituarização dos sensores possibilitaram a captação da energia eletromagnética refletida e transmitida pelos alvos na superfície, sendo posteriormente convertida em sinais elétricos de maneira que podem ser armazenadas ou transmitidas em tempo real. Os dados capturados pelos sensores são processados para serem utilizados no processo de aquisição de informações dos objetos observados na superfície terrestre para serem aplicados no gerenciamento dos recursos florestais

    Osmoprotectants play a major role in the Portulaca oleracea resistance to high levels of salinity stress—insights from a metabolomics and proteomics integrated approach

    Get PDF
    IntroductionPurslane (Portulaca oleracea L.) is a non-conventional food plant used extensively in folk medicine and classified as a multipurpose plant species, serving as a source of features of direct importance to the agricultural and agri-industrial sectors. This species is considered a suitable model to study the mechanisms behind resistance to several abiotic stresses including salinity. The recently achieved technological developments in high-throughput biology opened a new window of opportunity to gain additional insights on purslane resistance to salinity stress—a complex, multigenic, and still not well-understood trait. Only a few reports on single-omics analysis (SOA) of purslane are available, and only one multi-omics integration (MOI) analysis exists so far integrating distinct omics platforms (transcriptomics and metabolomics) to characterize the response of purslane plants to salinity stress.MethodsThe present study is a second step in building a robust database on the morpho-physiological and molecular responses purslane to salinity stress and its subsequent use in attempting to decode the genetics behind its resistance to this abiotic stress. Here, the characterization of the morpho-physiological responses of adult purslane plants to salinity stress and a metabolomics and proteomics integrative approach to study the changes at the molecular level in their leaves and roots is presented.Results and discussionAdult plants of the B1 purslane accession lost approximately 50% of the fresh and dry weight (from shoots and roots) whensubmitted to very high salinity stress (2.0 g of NaCl/100 g of the substrate). The resistance to very high levels of salinity stress increases as the purslane plant matures, and most of the absorbed sodium remains in the roots, with only a part (~12%) reaching the shoots. Crystal-like structures, constituted mainly by Na+, Cl−, and K+, were found in the leaf veins and intercellular space near the stoma, indicating that this species has a mechanism of salt exclusion operating on the leaves, which has its role in salt tolerance. The MOI approach showed that 41 metabolites were statistically significant on the leaves and 65 metabolites on the roots of adult purslane plants. The combination of the mummichog algorithm and metabolomics database comparison revealed that the glycine, serine, and threonine, amino sugar and nucleotide sugar, and glycolysis/gluconeogenesis pathways were the most significantly enriched pathways when considering the total number of occurrences in the leaves (with 14, 13, and 13, respectively) and roots (all with eight) of adult plants; and that purslane plants employ the adaptive mechanism of osmoprotection to mitigate the negative effect of very high levels of salinity stress; and that this mechanism is prevalent in the leaves. The multi-omics database built by our group underwent a screen for salt-responsive genes, which are now under further characterization for their potential to promote resistance to salinity stress when heterologously overexpressed in salt-sensitive plants
