Emergência de Bidens pilosa em diferentes profundidades de semeadura

Bidens pilosa é uma das mais importantes plantas daninhas que ocorrem em lavouras anuais e perenes da região Centro-Sul do Brasil. A grande capacidade de produção de aquênios é uma das suas principais estratégias de sobrevivência, e o conhecimento das condições fundamentais para germinação e emergência das plântulas é essencial para predição do crescimento populacional e para a elaboração de plano de manejo de suas infestações e de seus biótipos resistentes aos herbicidas. Foram conduzidos ensaios em condições de casa de vegetação, onde foi avaliada a emergência de aquênios de B. pilosa em diferentes profundidades (0, 1, 2, 3, 4 e 5 cm). Os experimentos foram conduzidos nos meses de maio, agosto e novembro de 2006 e em março de 2007. Os resultados mostraram que a emergência de plântulas de picão-preto foi bastante afetada pela localização do aquênio no perfil do solo, ocorrendo expressiva redução a partir de 2 cm de profundidade. Essa característica da biologia reprodutiva do picão-preto é importante para a formação de densos bancos de sementes em solos submetidos ao preparo convencional, onde grande parte da chuva de sementes é nele incorporada.

Compatibilidade entre acaricidas e fertilizantes foliares em função de diferentes águas no controle do ácaro da leprose dos citros Brevipalpus phoenicis

A adição de fertilizantes foliares à calda acaricida é frequentemente empregada na citricultura com o intuito de reduzir os custos das aplicações. Todavia, as implicações desta prática, na maioria dos casos, são desconhecidas. O objetivo do trabalho foi avaliar o efeito de caldas acaricidas em mistura com fertilizantes foliares e preparadas com diferentes águas no controle do ácaro B. phoenicis. Foram realizados dois experimentos em laboratório, nos anos de 2009 e 2010, utilizando-se de frutos de laranja para conter ácaros Brevipalpus phoenicis. Um dos experimentos constou de três bioensaios, nos quais se procurou verificar o efeito das misturas entre fertilizantes foliares e os acaricidas cyhexatin, propargite e acrinatrhrin sobre B. phoenicis. No outro experimento, além de verificar o efeito das misturas de fertilizantes com os acaricidas propargite e acrinatrhrin, buscou-se também avaliar o efeito de águas coletadas em diferentes fontes utilizadas no preparo das caldas sobre B. phoenicis. Os resultados evidenciaram que a aplicação dos fertilizantes foliares cloreto de zinco, cloreto de manganês, ureia e a mistura de fosfito de potássio + ureia + cloreto de zinco não afetaram a ação dos acaricidas cyhexatin, propargite e acrinathrin sobre o controle de B. phoenicis. As misturas dos cloretos de zinco e de manganês com o sulfato de magnésio e a adição de fosfito de potássio diminuíram a eficiência dos acaricidas propargite e acrinathrin, não devendo, a princípio, ser adicionadas numa mesma aplicação. Águas provenientes dos municípios paulistas de Itápolis, Pirangi e Pirassununga interferiram na ação dos acaricidas propargite e acrinathin sobre B. phoenicis, sendo que a água coletada em Itápolis apresentou resultados superiores em termos de eficiência. Verificaram-se alterações dos valores de pH e da condutividade elétrica após a adição de alguns dos fertilizantes à calda acaricida.

Variação das características físico-químicas e microbiológicas das salmouras empregadas na salga de queijos tipo mussarela durante o período de sua utilização

Foram analisadas 40 amostras de salmouras empregadas na salga por submersão de queijos tipo mussarela, em uma indústria de laticínios do Estado de São Paulo, Brasil, com o objetivo de se conhecer a variação das características físico-químicas e microbiológicas durante o período de sua utilização. Os valores médios do pH, concentração de cloreto de sódio e de proteínas solúveis, desde o preparo da salmoura até o 21° dia de utilização, variaram de 7,21 a 5,76, 27,1 a 24,5 e de zero a 0,126 mg/ml, respectivamente. Por outro lado, os valores médios das contagens de microrganismos mesófilos e do número mais provável de coliformes totais e de origem fecal variaram de 5,8 x 10 UFC/ml a 6,9 x 10(4) UFC/ml, zero a 1,6 x 10(5)/100ml e zero a 1,1 x 10(5)/100ml, respectivamente. Além disso, os valores médios das contagens de bolores e leveduras e de Staphylococcus coagulase positiva, variaram de 0,4 x 10 UFC/ml a 2,0 x 10³ UFC/ml e de zero a 1,3 x 10 UFC/ml, respectivamente. Os resultados encontrados sugerem a existência de condições higiênicas inadequadas durante o preparo e utilização das salmouras, de modo a representar uma importante fonte de contaminação para os queijos. em decorrência deste fato, existe a possibilidade do comprometimento da qualidade dos queijos, de modo a representar risco potencial à população consumidora.

A escola normal de natal (Rio Grande do Norte, 1908-1971)

The research aims to analyze Professor Education in Natal, Rio Grande do Norte-Brazil in the period of 1908 to 1971. The work falls under the theme History of Scholar Institutions as well as Professor Education. The research investigates the evolution of the so called Normal School, a school that aimed professor education. It was based on assumptions by works of Chartier (1990), Chervel (1990), Elias (1994), Nóvoa (1987), Schriewer (2000), amongst others. The research dealt with a great array of documents in different institutions such as Minutes, Public Instruction Management Reports, Laws, newspaper articles (from the newspaper A Capital, A Ordem e A República), magazines such as Pedagogium (1921-1940); all of which present in the Geographical and Historical Institute of Rio Grande do Norte in Brazil. In the State´s public archive it was possible to find a book called Livro de Honra (1914-1919) as well as class diaries and books that contained details related to Scholar group Inscriptions. In the Atheneu Memorial the Atheneu Congregation of Normal School (1897) document was analyzed. In the Kennedy Superior Institute the researcher analyzed the Professor Nominal Graduation Registry Book. The work proposes a comparative study regarding the genesis present in the Lisbon Primary Normal School and the ones situated in Natal. The analysis dealt with institutional meanings attributed by educators. Documents from The Portuguese National Library as well as the Lisbon Superior Education School were analyzed. In this in environment, it was possible to analyze documents such as Minutes, Books, Manuals, Internal Regiments related to Pedagogy. The study allowed acknowledging that these Normal Schools emerged from the same historical substrate and present consonance between the two countries regarding once both were associated with politicians, professors, doctors, hygienists and professionals evolved with education. It was also possible to acknowledge that there is a presence of a pedagogical discourse attached to the primary school universe and professor education. The Natal Normal School was present in different contexts and was consolidated as an institution that was responsible for the education and preparation of primary school teachers. The school was considered a locus where it was possible to produce and work with specific knowledge in a peculiar fashion. This knowledge provided the necessary support for professor education and was in accordance with the world´s professional pedagogical movement as well as ideas, discussions and reflections. This school was considered a space for pedagogical activities, professional affirmation allowing action reflection enabling professor representation as knowledge producers legitimating professor instruction

Exploratory descriptive study, with a quantitative approach and prospective data, performed in Pronto Socorro Clóvis Sarinho (PSCS), in Natal/RN, aiming to analyze care given by the nursing and medical staff to victims of violence attended to in an emergency hospital in Natal/RN; to identify care given by the nursing and medical staff as viewed by the victims; to compare data observed during the process of care with the victim s view on the care given by the nursing and medical staff; to identify the existing knowledge on violence and the process of caring for victims and its relation with prejudice; to identify obstacles and perspectives for prevention during the process of caring for victims in the emergency services. The population consisted of 97 physicians, 16 nurses, 75 nursing technicians and assistants and 365 victims of violence, with data collected from April to May 2009. Out of 188 professionals, 52.1% are female; 32% were aged 41 to 50; 99.5% had given care to a victim of violence; 90.4% reported to have given care to patients under custody; among these, 17.3% felt prejudice; 55.3% stated they don t provide different care for assaulted victims and assailants, however 44.7% stated they do; 86.7% feel their workplace is unsafe; 61.7% denied the existence of any obstacle and 38.3% reported the existence of obstacles; among these, 26.1% referred to inadequate facilities; 37.8% believe reinforcing security and professional training are the main solutions. Among the 365 researched violence victims, 82.2% were assaulted; male (69.6%); aged 18 to 24 (24.9%); hailing from the Greater Natal area (89.9%); on 19.7% the event happened on Saturday; during the night (48.8%); victim of physical assault (61.4%); produced by body force (27.7%); 24.4% were injured in the head and neck. 57% had used some drug, among which alcohol was predominant (75.5%). On 621 observations performed during the victim care process, when compared to the report of assaulted victims, there was a statistical difference, at 5% significance level, regarding reception, resistance from the professionals, questioning about the violent event, providing of guidance, interaction with the patient and the understanding of receiving proper care, and care resolution. In comparisons involving the observed and the assailant victims reports, there was a statistical difference regarding the resence of resistance from the professionals, performance of necessary procedures and the nteraction with the patient and the understanding of receiving proper care and 58.1% reported the nursing team was the one that provided the best care. We conclude that professionals had lready given care to assailant patients, acknowledge the importance of knowing how the vent took place and acquired this preparation during their practice. The most often referred bstacles that hinder assistance were: inadequate facilities, material deficit and lack of rofessional preparation. As solutions for these problems, they cited the reinforcement of ecurity and professional training

Vivências de docentes de enfermagem no ensino do cuidar

Care, in a global perspective, appears in the main quarrels as the necessary phenomenon that will have to permeate the thoughts, the perception and values for the change that will lead to the overcoming of a paradigmatic crisis. The professional care was attributed, in elapsing of history, to the Nursing. Its historical evolution and articulation with the social processes, political and scientific in prominence place, in what it says respect to human well-being, not objectifying to cure, but to comfort, to complement the weak capacities and to the establishment the present capacities, alleviating pain, in other words, caring. The Teaching of care in Nursing, suffered great influences of the biomedical model, being like this, the education in Nursing has been criticized for if being valid pedagogical models incapable to promote the growth of the subjects, keeping it passive before your life processes, showing fragilities, attitudes and questionable behaviors, dissonances, appearing the imminence of an act of to care and to educate that needs to be considered as dialectical and intersubjective act. The objective of this research is to understand the lived experience of the nursing teachers in the Teaching of Care, in order to reflect about the insert of Nursing in the current world context, watching the dialetics of the Teaching of care and the paradigm changes in the section health. It is a phenomenological research that used the analysis of the located phenomenon, to obtain the units of meaning of the speech Nursing teachers about your experience lived in the Teaching of care. This study allowed the Nursing teachers could share your existences, senses and information on the interior of your pedagogic action exalting the interpretation, which appears intentionally in the conscience, emphasizing the pure experience of the be-professor, including emotions and affectivities in the teaching of care. In the construction of the results, three moments were devoted for discussion: Multidimensional Care; Care as Professional Practice; and the Teaching of care. The speeches had revealed rich, complex and for paradoxical times. The understanding of a sensitive teaching, that sometimes, arrives if to worry in rescuing the tenderness and the humanity, it is running into the other permeated speeches of fragilities, inconstancies, technifying, that showed lacks of pedagogic preparation. The Teaching of care needs to adopt a conception of education/learning and to use methodologies that can lead to an action liberating, capable to breach with traditional mooring cables and preconceptions or little healthful habits of life, favoring the use of methods that promote educating for the way of the sensitive, detaching aspects that they contribute for this end, as the intuition, the emotion, the creation, the perception and the sensibility. In this direction, it is considered important to deepen subjects that make possible the creation of care strategies and educational with the human being vision in your totality, therefore if it perceives that the necessary therapeutical boarding to be ampler, passing for the social individual, family and its relations

Representações sociais sobre a prática do cuidado para enfermeiros da saúde indígena: um estudo transcultural

The desire to research on this subject arisen from the experience as nursing in the indigenous health, where I observed that many professionals from all regions of Brazil chose to work within this zone. It was notorious the nurse s difficult to settle in only one place for a long length of time. Probably due to health care in indigenous zones happens from a cultural confront. This confront materialize because both sides are imbued with their own culture: in one hand the nurse professional with its scientific knownledgment on the other the indigenous with their rituals and peculiars habits. In this context nurses should delineate and negotiate the reality through symbolic representations of life, and then make questions on the new reality. In this way, this study set out with the aim of apprehends the nurse s social representations of transcultural care in indigenous health. This knownledgment is important to avoid possible conflicts, shocks, difficulties and health care incongruence within this context. The data collect was carried out on a range of non structured interview guided by a pre-elaborated questionnaire with four questions and a hand drawing related to nurse s health care in the indigenous health. This research had a sample of 17 nurses from the Indigenous Sanitary District of Manaus in the Amazon State. To interpret data we used the Discourse of the Collective Subject, which findings were presented in three chapters: characterization of participants, discussion on themes prevalent in discourse; social representation of nursing care through infographics. The analysis revealed that the care in the indigenous health is challenging because the native people imbued in its world are perceived and processed according to the nurse s cultural lens, leading to materialize of some strangeness and adaptation difficulties, especially in the first contacts. The Social Representation on nursing practice, in many cases, is projected and contrived on the basis of scattered believes and on perception derived from common sense. The findings shows that representions are essential to mitigating the initial strangeness and help nurses to better situate themselves in the new universe. The nurse s practice in the indigenous health care should merge into each other. From the Social Representations is possible to perceive that assimilation, also comprehension on indigenous health system and its traditional knowledge are important to developing strategies to improve access and quality of care for indigenous peoples. After analysis the nurse s discourses and drawings, it is possible to represent the nurse s practice in the indigenous health as anthropophagism, since nurses should literally consuming its patients culture, digesting it and seize it as means to provide culturally congruent care. We highlight the urgent need for preparation and training of professionals to work more effectively with indigenous peoples
