Efeitos do fósforo e potássio no rendimento e em outras características agronômicas do algodoeiro herbáceo

Com o objetivo de estudar o efeito da utilização de doses de fósforo e de potássio no rendimento e nas características agronômicas do algodoeiro (Gossypium hirsutum L.), cv. IAC 20, foi conduzido um experimento em 1994/95, num Latossolo Vermelho-Escuro do Campo Experimental da Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA)-Centro de Pesquisa Agropecuária do Oeste (CPAO), em Ponta Porã, MS. O delineamento experimental foi o de blocos ao acaso, num esquema fatorial 3 x 5, com quatro repetições. As doses foram de 30, 60 e 90 kg ha-1 de P2O5, na forma de superfosfato triplo; 0, 30, 60, 90 e 120 kg ha-1 de K2O, na forma de KCl. Somente as doses de K2O influenciaram significativamente o rendimento de algodão em caroço, a altura da planta e o peso de 100 sementes e dos capulhos.

Características agronômicas e qualidade comercial de cultivares de milho pipoca em alta população

Com o objetivo de identificar cultivares de milho pipoca que se constituam em alternativa viável aos produtores foi conduzido um experimento em delineamento experimental de blocos casualizados, com cinco genótipos de milho pipoca (BRS Ângela, Zélia, IAC 112, IAC 12 e IAC TC-01) e quatro repetições, na safra 2003/2004. O experimento foi instalado em espaçamento entre as linhas de 60 cm, com densidade populacional de 75 mil plantas por hectare. No decorrer do experimento, foram avaliadas características agronômicas e comerciais em condição de campo e de laboratório. A variedade BRS Ângela apresentou maior produtividade, seguida pelos híbridos simples IAC, com Zélia (híbrido triplo) apresentando menor produtividade. O híbrido simples IAC 12 apresentou pior qualidade comercial de pipoca. A produção de grãos está associada positivamente com o número de grãos por espiga e com a massa de 1.000 grãos e negativamente com o teor de Ntotal no grão. A qualidade comercial se correlacionou negativamente com a massa de 1.000 grãos.

Características agronômicas de arroz de terras altas sob plantio direto e adubação nitrogenada e potássica

Da negatividade a positividade: possível trânsito de saberes, práticas e representações sociais sobre o estigma da hanseníase

Leprosy is a chronic infectious-contagious disease, caused by Mycobacterium leprae, manifested by dermatological and neurological signs and symptoms and has great disabling power. It was marked by a strong stigma throughout its history, since its bearers represented a threat, target of fear and social contempt. Currently, leprosy has treatment and cure, and the need to separate the diseased from family and social environment is no more necessary. However, patients still suffer prejudice and discrimination. This study aimed to understand the social representations of leprosy that interfere modifying mental health of the patient with leprosy in relation to stigma and prejudice. This is a descriptive and exploratory study, with qualitative approach, which involved 22 users of the Special Care Clinic in Infectious Diseases at the Hospital Giselda Trigueiro, located in Natal / RN. They were in use of multidrug therapy in the period of data collection, were of both sexes, aged between 16 and 80 years of age and classified as paucibacillary or multibacillary. The study was approved by the UFRN Ethics in Research Committee. Data collection was performed by filling the questionnaire identification and then for conducting the semi-structured interview, which was recorded. After the end of data collection, there was the construction of tables and graphs, using the Microsoft Excel Start 2010 for proper characterization of the research subjects; and for the treatment of the data obtained from the interviews, was used the Content Analysis and based on the Theory of Social Representations. The subjects studied were mostly male (64%), married or in a stable relationship (68%), concentrated in the age group 50-60 years (36%) and 28-38 years (23%), had at most elementary education (65%) and were low-income (59%). Of the total respondents, 64% were classified as multibacillary, with predominantly dimorfous form, and 50% had disability grade I or II, with different periods of diagnosis. The reports originate two categories: 1. The negative meanings of illness and leprosy; and 2. The positive meanings of illness in leprosy, which were subsequently subdivided into subcategories. Thus, it was found that in the group studied, the social representation of leprosy experiences a moment of transition, as regards the understanding of the disease and its way of experiencing the disease process. Such representation is anchored in the quality of information on the disease of its bearers and aimed at an attempt to face the illness of leprosy as a "normal process". It was found in this study that the transition is due to the work of combating stigma and consequences of leprosy, which is able to gradually transform reality, both regarding the team work of reference, and in relation to a broader character, of actions of health education, which favors overcoming of psychosocial disabilities

Práticas populares de cuidado à criança: o saber/fazer de cuidadoras

Popular practices correspond to the resources used by households, lay people and popular therapists, whose perception of knowledge is constructed in the everyday. In this context, the sick child can become vulnerable to be dependent on a family caregiver, who often decide to employ popular practices. Thus, the child care should be shared between carer and health professional. However, they know little about the resources that the family uses to detect a grievance in infant. Therefore, the present research aimed to analyse the use of popular practices by caregivers of children with zero to five years old. We conducted an exploratory and descriptive study with a qualitative approach, together with 15 caregivers of children who were treated at the Joint Unit Felipe Shrimp, located in Natal, Rio Grande do Norte, Brazil. To select the participants, they should be age and above 18 years; be caregivers of children up to five years of age; and reside in the area ascribed the Joint Unit Felipe Shrimp. The data collection took place between September and October 2013, through in depth interview. This step was preceded by the approval of the Health Department of the city of Natal; the direction of the Joint Unit Felipe Shrimp; as well as, the Committee on Ethics in Research from the Federal University of Rio Grande do Norte with Certificate of Presentation and Consideration Ethics, No 15467013.8.0000.5537. Furthermore, the interviewees formally authorized their participation in the research by signing the consent form. The data were treated according to the technique of content analysis in the form of thematic analysis according to Bardin. This process, four categories emerged: "Types of popular practices used in the care of the child"; "Source of information of popular practices"; "Results obtained with popular practices"; "Factors that hinder the adoption of common practices." The results showed the use of popular practices by caregivers in the case of illness to children such as the homemade preparations with medicinal plants and folk healers. The family environment was referenced as the main learning space and spread of popular practices, which are influenced by cultural relations present in this context. As to the results obtained with popular features, the caregivers said to be satisfactory, and this triggers a feeling of confidence and acceptability of such measures. It is concluded that the use of popular practices in child care persists in everyday most of the participants, despite the hegemony of allopathic therapy. The caregivers stated that such practices are effective and easy to obtain, being secured in context by popular culture. In addition, health professionals, especially nurses, were seldom mentioned by the caregivers as to the information concerning popular resources used by them, which suggests the weakness in dialogic process of negotiating practices between both of them

Características agronômicas e composição química de oito híbridos de sorgo [Sorghum bicolor (L.) Moench]

O experimento foi conduzido com o objetivo de avaliar as características agronômicas, composição química das frações e da planta inteira de oito híbridos de sorgo, semeados em março de 2000, no sentido de contribuir para os programas de seleção de germoplamas resistentes aos efeitos das estiagens prolongadas e, ao mesmo tempo, apropriados ao processo de ensilagem. Utilizou-se o delineamento em blocos ao acaso com oito tratamentos e três repetições, para avaliar os híbridos AG-2005, BR-700, MASSA-03, 498111, 65E3, 698005, 698007 e 699005. Não houve diferenças significativas entre produção de matéria seca (PMS) e proporção de folhas dos híbridos avaliados. A maior proporção de colmo (41,3%) foi observada no 498111 e a menor no MASSA-03 (28,9%). O híbrido 65E3 apresentou a maior proporção de panícula (43,2%) e o 498111 a menor (28,9%). Quanto à composição química da planta inteira, não foram observadas diferenças significativas entre os híbridos quanto aos teores de matéria seca, matéria mineral, hemicelulose, nitrogênio insolúvel em detergente neutro, nitrogênio insolúvel em detergente ácido e nutrientes digestíveis totais (NDT). Os teores de proteína bruta variaram de 6,5 a 8,8%, fibra em detergente neutro de 57,0 a 70,3%, fibra em detergente ácido de 29,8 a 36,2%, celulose de 25,3 a 31,2% e lignina de 3,6 a 5,5%, sendo estatisticamente diferentes entre os híbridos. O 699005 apresentou o maior teor de carboidratos solúveis (14,5%), diferindo estatisticamente apenas do híbrido 698007 (9,6%). Os híbridos também mostraram diferenças na composição química das frações folhas, colmo e panícula. de forma geral, todos os híbridos apresentaram teores de matéria seca e carboidratos solúveis adequados ao processo de ensilagem. As produções médias de matéria seca dos híbridos (6,2 t/ha), foram altas considerando-se a baixa precipitação ocorrida durante o período experimental. A análise de Cluster sugeriu o agrupamento dos híbridos de maior PMS e menores porcentagens de panícula e NDT e híbridos de menor PMS, porém com maiores porcentagens de panícula e NDT.

Educação ambiental em Natal/RN: um olhar sobre a implementação de práticas em uma escola da rede municipal de ensino

This work provides a discussion involving the development of practices in Environmental Education (EE) in Natal-RN city, taking as reference the Programa Vamos Cuidar do Brasil com as Escolas (PVCBE). The EE is emphasized by importance it takes within the context of the reforms carried out in Brazil to formal education, especially from the decade of 1980. The investigations focus the effect of PVCBE in promoting the EE. We take as theoretical - methodological base the global/national guidelines on EE, carried out the non-participant observation, document analysis, and application of questionnaires and use of statistical techniques in the data tabulation. The results indicate that there has been reasonable progress to the achieving of an implementation policy of EE clearly qualitative, with a better coordination among municipal policymakers and the schools involved. It has been also noticed that there is a gap between what the law provides for a formal EE and what is carried out in practice. Despite the limitations noted, we must remember that actions have been achieved. Even considering that they are isolated action; they already show that there are possibilities of follow ways to processes based on the criteria of integration, reflexive action, quality and autonomy

A influência da cultura organizacional na adoção de práticas de qualidade Seis Sigma: um estudo exploratório no segmento de farmácia de manipulação do Estado do Rio Grand do Norte

In recent debates about the issues of quality, the theme organizational culture and Six Sigma has appeared ever more frequently. In this context several authors suggest that the adoption of Six Sigma practices is influenced by culture. This work focuses on the relationship of organizational culture and quality to the practices of Six Sigma quality. Thus a descriptive-exploratory and correlational study of forty pharmacies of manipulation from Rio Grande do Norte was undertaken. Data collection identified features of companies and the level of use of the practices of Six Sigma quality that have been identified in the literature. For the Organizational Culture evaluation was used the Competitive Value Model (Cameron & Quinn, 1996), tested on north-American organizations and considered a high value academic and professional instrument. This model has been involved with the taximetrics created by Cameron who classifies quality culture in four levels. The results suggest that the Group and Developmental cultures are associated with higher levels of use of the practices of Six Sigma quality than the Rational and Hierarchical Cultures. Regarding the levels of the culture s quality, the highest levels were most frequently cited in Errors Prevention and Perpetual Improvement and Creativity, being the last one more positively related to the Six Sigma indicators
