Sintomas de deficiência nutricional em mudas de Acacia holosericea em resposta à omissão de macronutrientes

A Acacia holosericea é uma espécie leguminosa arbórea bastante utilizada na recuperação de áreas degradadas. O conhecimento dos sintomas de deficiência nutricional apresentados por esta espécie possibilita a identificação e a correção de deficiências em exemplares plantados em substratos degradados. Os objetivos deste trabalho foram caracterizar a sintomatologia visual de carências de macronutrientes e avaliar a produção de biomassa e o acúmulo de nutrientes nas raízes e na parte aérea de mudas de Acacia holosericea, submetidas a diferentes soluções nutritivas com exclusão de macronutrientes. Os tratamentos constituíram-se de sete soluções nutritivas: 1) solução completa (SC); 2) SC -N; 3) SC -P; 4) SC -K; 5) SC -Ca; 6) SC -Mg; e 7) SC -S. Os tratamentos -N e Mg foram os que mais afetaram a produção total de biomassa. O decréscimo de produção manifestou-se na seguinte ordem: -N = -Mg > -K > -S > -Ca > SC > -P. As plantas do tratamento -N formaram nódulos no sistema radicular, exibindo teores foliares de N maiores que as plantas do tratamento SC. Com exceção dos tratamentos SC e -P, todos os outros apresentaram sintomas de deficiência. A ausência de S alterou a disposição natural dos filódios novos da A. holosericea.

Diagnóstico de deficiência de macronutrientes em mudas de teca

O trabalho teve como objetivo caracterizar a sintomatologia visual e o crescimento e teor de nutrientes na parte aérea e no sistema radicular de mudas de Tectona grandis, transferidas para soluções nutritivas com exclusão de macronutrientes. As mudas foram produzidas em substrato comercial, onde permaneceram por quatro meses, sendo depois transferidas para rizotrons, em que foram submetidas, por 30 dias, à solução nutritiva completa e soluções preparadas com a supressão de N, P, K, Ca, Mg e S. O delineamento foi inteiramente casualizado, com cinco repetições. As soluções foram renovadas a cada duas semanas e o volume, completado diariamente com água desionizada, mantendo-se o pH em torno de 5,5 + 0,5. O desenvolvimento inicial de mudas de Tectona grandis foi afetado pela omissão de todos os macronutrientes, sendo os sintomas condizentes com o padrão apresentado pela maioria das culturas. Os danos mais intensos e imediatos foram observados na ausência de N e Ca, causando, inclusive, apodrecimento das raízes secundárias e paralisação na emissão de novas raízes. Os teores nutricionais da parte aérea e sistema radicular das mudas submetidas à solução completa foram, respectivamente: 38,0 e 26,9 g kg-1 de N; 8,5 e 4,0 g kg-1 de P; 22,8 e 13,1 g kg-1 de K; 2,3 e 3,7 g kg-1 de S; 10,5 e 2,0 g kg-1 de Ca; 3,0 e 1,7 g kg-1 de Mg; 175,2 mg kg-1 e 3,6 g kg-1 de Fe; 23,1 e 48,1 mg kg-1 de Zn; 4,3 e 17,8 mg kg-1 de Cu; e 142,5 e 389,8 mg kg-1 de Mn.

Pensar a deficiência numa perspetiva inclusiva

O que há de mais cultural do que definir a deficiência e dar-lhe respostas? A deficiência afecta a pessoa mas também o seu contexto mais alargado, pressionando a ordem cultural reinante. Vem de qualquer modo corromper o ideal enraizado numa cultura. Um ideal que delimita a conformidade, define os “fora da lei”, elabora categorias, vigia o conformismo das pessoas, cria e sustenta processos de interação, de oposição ou de segregação. Este artigo interroga os modos de a conceber e de a tratar na nossa cultura. Questiona de facto o formato estabelecido e as representações culturais comuns. Numa perspetiva inclusiva, convida a uma “desconstrução” e a “Novas Luzes” em relação à deficiência.

The sight of silence : the conceptualisation of silence in the visual cultures of sign language communities

Deaf people are perceived by hearing people as living in a silent world. Yet, silence cannot exist without sound, so if sound is not heard, can there be silence? From a linguistic point of view silence is the absence of, or intermission in, communication. Silence can be communicative or noncommunicative. Thus, silence must exist in sign languages as well. Sign languages are based on visual perception and production through movement and sight. Silence must, therefore, be visually perceptible; and, if there is such a thing as visual silence, how does it look? The paper will analyse the topic of silence from a Deaf perspective. The main aspects to be explored are the perception and evaluation of acoustic noise and silence by Deaf people; the conceptualisation of silence in visual languages, such as sign languages; the qualities of visual silence; the meaning of silence as absence of communication (particularly between hearing and Deaf people); social rules for silence; and silencing strategies.

Aspectos laboratoriais do diagnóstico da deficiência de glicose-6-fosfato desidrogenase (G6PD)

A G6PD é expressa em todos os tecidos, onde catalisa a primeira etapa da via das pentoses-fosfato. O NADPH produzido pela ação da G6PD serve como doador de elétrons na biossíntese redutora. Pelo fato de os glóbulos vermelhos não terem mitocôndria, a via das pentoses-fosfato é a única fonte de NADPH e essencial para sua proteção contra o stress oxidativo. A deficiência da G6PD é classificada como anemia hemolítica hereditária ligada ao cromossomo X, associada a manifestações clínicas heterogêneas. O gene da G6PD possui cerca de 140 variantes moleculares já descritas, muitas dessas associadas à enzimopatia. Considerando-se a alta freqüência populacional da deficiência de G6PD, a constituição da população do Rio Grande do Sul e as dificuldades diagnósticas desta deficiência, este trabalho teve como objetivo caracterizar os aspectos laboratoriais do diagnóstico da deficiência de G6PD em nosso meio. Para a quantificação da atividade da G6PD, foi utilizado o método enzimáticocolorimétrico com normalização da hemoglobina (kit intercientífica) e para as análises moleculares foram investigadas as mutações 202, 376 e 563 por PCR/RFLP. O presente estudo revelou uma prevalência combinada de 7,9% das duas formas de deficiência de G6PD (completa e parcial) no Rio Grande do Sul, com alta prevalência de pacientes parcialmente deficientes e sem correlação com origem étnica. Usando técnicas bioquímicas e moleculares, foi caracterizada a deficiência de G6PD em amostras de Porto Alegre como sendo principalmente devida às mutações G202A e A376G, representando a variante G6PD A-, confirmando uma distribuição homogênea do padrão G6PD A- no Brasil. Os resultados apresentados aqui demonstraram que as condições de estocagem (temperatura principalmente) desempenham um papel fundamental na atividade da G6PD, especialmente nas coletas em papel filtro. Na avaliação da acurácia do método enzimático de medida da atividade da G6PD as sensibilidades e especificidades calculadas para os valores de cut-off estabelecido em uma população normal foram: para 2,9 U/gHb ( 11,4% e 100%), para 8 U/g Hb (77,1% e 94,7%) e para 11,5 U/g hb (97,1% e 76,3%). Estima-se que a deficiência de ambas as formas combinadas de G6PD seja de aproximadamente 8% numa amostra do RS. A partir de uma probabilidade pré-teste de 8,0%, após a realização do ensaio enzimático, a probabilidade pós-teste de uma pessoa ser deficiente de G6PD com nível enzimático inferior a 8 U/g Hb passa a ser 55,9%. Ao passo que para níveis superiores a 11,5 U/gHb esta probabilidade de deficiência diminui para 0,37%. Pode-se concluir que o método empregado (kit Intercientífica) foi adequado para avaliar a atividade enzimática de G6PD em amostras de sangue total. É um método capaz de detectar a deficiência de G6PD, demonstrando de forma satisfatória o grau de deficiência em indivíduos que possuem mutações que causam deficiência enzimática menos severa, inclusive mulheres heterozigotas. A análise molecular pode identificar o tipo de variante mas não pode indicar o risco real para as mulheres portadoras, que é diretamente estimado pelo nível de atividade enzimática.

"Reforma urbana já"; "arroz, feijão, saúde e habitação" :A luta por moradia na grande João Pessoa

Our object of study in this work concerns to the movement of fight for the housing in the Great João Pessoa, Paraíba, Brazil, and looks for to investigate the conditions and context of the occupations of building, public or private, for devoid populations that do not have where to live. Front to the absence of politics effective directed to the habitation or the cities, in a picture of unemployment and impoverishment of the population, the result of the habitation point of view, is the absolute lack of popular housings, the degradation of the cities and the growth of the number of homeless and also of its occupations. The urban occupations today represent a reply of these devoid populations that from an involvement with parties or Not Governmental Organizations, and social movements leave for the class action known by the occupation of abandoning public or private buildings. These occupations, even so initially if assume as pressure instrument or of visibility for attainment of housings, for the delay in obtaining the attention of the public agencies and a solution for the problem, becomes definitive or is drawn out per many years. E this if gives although the deficiencies, of the accumulation or families neither in an adequate, always precarious space nor in sanitary installations, that the necessary privacy does not allow. The study it consisted of an empirical research, through the participant comment and open and half-open interviews, and counted on the audiovisual register of two occupations, one in the downtown of João Pessoa City (old building of the INSS, in the Ponto dos Cem Réis) and other (Community of the Cajueiro), next to the Beach "Praia do Jacaré", in the city of Cabedelo.The choice of the Visual Anthropology as research instrument is on to a concern in better translating other ways of life, therefore the accomplishment of the video in allows them to know with more precision the reality where the citizens of the research live. We also use as methodological resource in the research the deepened interview, in intention to better understand the description of the way of life of the studied families and the movements of fight for the housing, particularly the MDM - Movement of Right for the Housing, and the MNLM- Nacional Movement of Fight for the Housing

Acesso e permanência na universidade federal do rio grande do Norte sob o ponto de vista do docente e do estudante com deficiência Natal-RN

Inclusion of students with disabilities is a recent case that has been discussed in school contexts, but the current policy of inclusion for access and retention of students in higher education is still a problem face there is much to do, therefore, are incipient studies in which this student body is involved. Accordingly, what is happening is that the most studies deal with on these students and little is said about them. For inclusive education thus the institution should prepare to receive students, having as one of its premises their point of views about what actually experience aiming at promoting education for all. Therefore, this study deals with the process of inclusion of students with disabilities regularly enrolled in undergraduate courses at the Universidade Federal do Rio Grande do Norte - UFRN.They were used the assumptions of qualitative research enabled by the case study method and semi-structured interviews. It has been analyzed by guiding actions and teaching practices, under the views of disabled students and teachers, the conditions of access and permanence offered by UFRN. Twelve students with physical, visual, hearing disabilities participated and five teachers from the acedemic centers that in academic year 2008 taught to these students. For data analysis it was used the technique of content analysis. It was extracted two themes: access and retention of students with disabilities in UFRN, in which emerged the categories described and analyzed in the course of this work. The results show the difficulties of access and retention of students with disabilities within the UFRN, such as attitudinal, pedagogical and architectural barriers. However, as it has also turned out, initial advances in the quest for achieving more effective actions to guarantee access and permanence of these students in UFRN. It has concluded that the scope for the exercise of citizenship in the pupils with disabilities who need this Higher Education Institution has an inclusive education Project, wide and consolidated, for the actions undertaken by the Ministry of Education - MEC, by itself, are not guaranteed to all students due to mobility, autonomy and security. It has hoped this work will bring benefits for new studies to develop features that were located, but were not our focus, because then the UFRN may advance the inclusive process of disabled students

Diagnósticos de enfermagem em pacientes submetidos à hemodiálise: semelhanças entre o modelo de adaptação e a NANDA internacional

The nurses in the hemodialysis has an important role in the nursing process implementation, in the context of a theoretical referential. Among the nursing theories, highlights the Roy´s adaptations model, who considers a person as an holistic adaptive system that aims to adapt customers to different living conditions. Thus, it is believed that the Roy´s nursing process will guide nursing care to patients on dialysis. Therefore, the study aimed to analyze the nursing diagnosis present in patients with chronic kidney disease on hemodialysis based on the theoretical model of Roy and NANDA-International. Descriptive and cros-sectional study, performed at a dialysis center in a city in northeastern Brazil. Sample of 178 patients and consecutive sampling by convenience. Data collection ocurred from October/2011 until February/2012, through interview and physical examination forms. Data analysis was initiated by clinical reasoning, diagnosis judgment and similarity relation. Then, the data were entered into SPSS program, 16.0 version, generating descriptive statistics. The project was approved by the Ethics Research Committee (protocol nº 115/11) with a Presentation Certificate for Ethics Appreciation (in 0139.0.051.000-111) and was funded by the Universal edict MCT / CNPq 14/2010. The results revealed that most patients were male (52.2%), married (62.9%) and residents in the Natal´s metropolitan region (54.5%). The mean age was 46.6 years and the years of study, 8,5. Regarding nursing diagnosis obtained an average of 6.6, especially: Risk of Infection (100%), excessive fluid volume (99.4%) and hypothermia (61.8%). On the other hand the adaptive problems average was 6.4, and the most common: intracellular fluid retention (99.4%); Hyperkalemia (64.6%); Hypothermia (61.8%) and edema (53.9%). Were established 20 similarity relations between the NANDA-International nursing diagnosis and adaptive problems of Roy, namely: risk of falls / injury risk and potential for injury, impaired physical mobility and walking mobility and / or restricted coordination, dressing self-care deficit and loss of self-care ability; hypothermia and hypothermia; impaired skin integrity and impaired skin integrity; excessive fluid volume and intracellular fluid retention / Hyperkalemia / Hypocalcemia / edema; imbalanced nutrition: less than body requirements and Nutrition less than the body's needs; constipation and constipation, acute pain and acute pain, chronic pain and chronic pain, sensorial perception disturbed: visual, tactile and auditory disabilities and a primary sense: sight, hearing and tactile; sleep deprivation and insomnia, fatigue and intolerance to activities; ineffective self health and fails in the role; sexual dysfunction and sexual dysfunction; situational low self-esteem and low self-esteem, and diarrhea and diarrhea. We conclude that there is similarity between the typologies and was required a model´s analysis, because they present different ways to establish the nursing diagnosis. Moreover, the nursing process use, under the context of a theory and a classification system, subsidizes the care and contributes to the strengthening of nursing science

Sintomas de deficiência tardia de fósforo em soja

Foi notado, em área de cultivo experimental em Botucatu (SP), que a soja, na época de enchimento das vagens, apresentava folhas com cor amarelada, que evoluía para palha, com tons arroxeados no limbo foliar e nos pecíolos. Esses sintomas eram compatíveis com as descrições mais genéricas de deficiência de P para outras espécies, apesar de não estarem descritos para soja. Foi conduzido um experimento em vasos com areia lavada e solução nutritiva, com o objetivo de reproduzir os sintomas observados em condição de campo. Foram cultivadas três plantas de soja por vaso, em ambiente aberto. Os sintomas de deficiência de P apareceram inicialmente nas folhas mais velhas, que ficaram amareladas, conservando algumas nervuras verdes. O tom amarelado foi-se intensificando, adquirindo tons avermelhados e, posteriormente, arroxeados. Notou-se ainda colapso do pecíolo das folhas com sintomas de deficiência. A fase de pegamento de vagens de soja mostrou-se mais sensível à deficiência de P do que a fase de enchimento de grãos podendo ocorrer recuperação de parte da produtividade pela produção de menor número de grãos e vagens chochas e aumento no tamanho de grão, se a deficiência ocorrer tardiamente e não for muito severa.

Escuta clínica e atitude fenomenológica no atendimento à pessoa surda: reflexões sobre um processo psicoterápico

Psychology uses listening as a work resource. When it comes to psychotherapy, listening establishes communication and makes psychologist-client dialogue easier. This qualitative research aims to discuss the clinic listening in phenomenological attitude in existential-phenomenological psychotherapy with deaf people. This perspective is based on the thinking of German philosopher Martin Heidegger, who considers humane a being-with and being-in-the-world, always unveiling meanings. Regarding the deaf people, Libras is currently the natural language of Brazilian deaf people. In this new language configuration, communication occurs in a visual-spatial modality. Thus, listening and speech gain new dimensions, demanding different ways of understanding in the field of psychotherapy. To the development of this research, we present excerpts from therapeutic sessions narratives with a deaf client, interpreted in the light of Heidegger s hermeneutics. We consider that it is possible for the psychotherapist to listen to deaf people in phenomenological attitude. Such position, which does not naturalize and limit the humane, helps so that the clients do not feel responsible for their existence and can hermeneutically converse in their language. In this context, the psychologist must be qualified to conduct the treatment in Libras. We hope that this research can, somehow, fill the existing gap of the scientific production about such theme in the field of Psychology and, mainly, instigate discussion in the context of Psychology courses on the importance and need to qualify psychologists for the management of clinical practice with deaf people

Um estudo das condições de percolação e estabilidade em barragens de terra mediante métodos geofísicos: caso do dique de Sant Llorenç de Montgai - Espanha

The monitoring of Earth dam makes use of visual inspection and instrumentation to identify and characterize the deterioration that compromises the security of earth dams and associated structures. The visual inspection is subjective and can lead to misinterpretation or omission of important information and, some problems are detected too late. The instrumentation are efficient but certain technical or operational issues can cause restrictions. Thereby, visual inspections and instrumentation can lead to a lack of information. Geophysics offers consolidated, low-cost methods that are non-invasive, non-destructive and low cost. They have a strong potential and can be used assisting instrumentation. In the case that a visual inspection and strumentation does not provide all the necessary information, geophysical methods would provide more complete and relevant information. In order to test these theories, geophysical acquisitions were performed using Georadar (GPR), Electric resistivity, Seismic refraction, and Refraction Microtremor (ReMi) on the dike of the dam in Sant Llorenç de Montgai, located in the province of Lleida, 145 km from Barcelona, Catalonia. The results confirmed that the geophysical methods used each responded satisfactorily to the conditions of the earth dike, the anomalies present and the geological features found, such as alluvium and carbonate and evaporite rocks. It has also been confirmed that these methods, when used in an integrated manner, are able to reduce the ambiguities in individual interpretations. They facilitate improved imaging of the interior dikes and of major geological features, thus inspecting the massif and its foundation. Consequently, the results obtained in this study demonstrated that these geophysical methods are sufficiently effective for inspecting earth dams and they are an important tool in the instrumentation and visual inspection of the security of the dams

Fotografia e marketing: uma análise dos atrativos turísticos da cidade de João Pessoa-PB

Photography is a resourse of the most used and effective marketing, besides being an polysemic art, boundless sense; this allows for different readings. Nevertheless, there are those who, through the control and supervision, try to organize its meaning, such as the marketing companies. Others, such as artists, are the responsibility of the observers to give their work some understanding. Resorting a photographic iconography of the tourist attractions of the city of João Pessoa in Brazil from 2005 to 2010. This survey selected images published in catalogs supported by the Fundo de Incentivo a Cultura (FIC) and the Empresa Paraibana de Turismo (PBTUR). The central idea of this qualitative research is the assumption that, in general, tourists crave, even unconsciously, a reality of a tourist attraction motivated by photographic image conveyed the travel market, meanwhile, emphasizes that the art market, the same attraction is exposed and uncovered. Thus it is argued, by photos, such as environmental and sociocultural characteristics are commodified by these organs that have different purposes is not exclusive, given that the FIC supports art and PBTUR sponsors the tourism. Beyond the iconography used for cataloging and photographic analysis, interviews were conducted by the method of visual narratives in ordes to approximate the data with the view of tourists and photographers. In that resulted in a refletion on the current imagistic process involving the release of the tourist destinations in order to be allowed on a critical reading of photographic production and market resources to marketing and promoting the art of the city. It was observed that both the art and photography marketing acquire different symbolic values with respect to their markets promoted by the catalogs analyzed.
