Caroline de Moura D’Andréa Mateus, Kathia Fernandes Lopes Pivetta, Roberto Lyra Villas B?as, Regina Maria Monteiro de Castilho, Maria Márcia Pereira Sartori, Renata Bachin Mazzini-Guedes
American Journal of Plant Sciences (AJPS) , 2018, DOI: 10.4236/ajps.2018.92020
Abstract: Amaryllis plants (Hippeastrum hybrid, in the family Amaryllidaceae) are cultivated in Brazil mainly for bulb export. Studies about the nutrient accumulation dynamics by the species are yet incipient when considering Brazilian cultivation conditions. The objective was to determine the nutrient accumulation in amaryllis “Orange Souvereign” cultivated in the field. The experimental design was entirely randomized with four replications and 14 collection periods (at 30, 60, 90, 120, 150, 180, 210, 240, 270, 300, 330, 360, 390, and 420 days after planting). Sampled plants were divided into leaves, bulb, and roots, which were used for determination of nutrient accumulation by leaves (aerial part) and bulb + roots (underground part). Nutrient accumulation of N, P, K, Ca, Mg, S, B, Cu, Fe, Mn, and Zn was calculated for each collection period, and then represented by curves of macro and micronutrient accumulation, as well as accumulation percentages for each plant part. For most macro and micronutrients, the interval of maximum accumulation fell from 301 to 420 days after planting, matching with the cycle final stage of plants cultivated in the field. Accumulated macronutrients by amaryllis plants along the cultivation cycle was, in g·plant-1: 1.57 N; 0.19 P; 2.58 K; 0.64 Ca; 0.20 Mg; and 0.29 S, following the descending order: K > N > Ca > S > Mg > P. Accumulated micronutrients, in mg·plant-1, was: 2.18 B; 1.17 Cu; 22.33 Fe; 2.19 Mn; and 4.09 Zn, following the descending order: Fe > Zn > Mn > B > Cu.

Abstract: O lodo de esgoto pode ser uma alternativa viável na aduba o organica da alface, em solos arenosos. Avaliou-se a produtividade e a qualidade dessa cultura por meio de um experimento de campo, comparando a aplica o de lodo de esgoto da cervejaria Equatorial, com a de esterco de galinha. Os tratamentos consistiram de aduba es com lodo de esgoto, lodo de esgoto + NPK, esterco de galinha, esterco de galinha + NPK, NPK e controle. A produ o e a qualidade comercial da alface cultivada com lodo de esgoto de cervejaria n o diferiram em compara o ao tratamento com esterco de galinha. N o houve diferen a no teor de macronutrientes nas folhas dessa cultura, com a utiliza o do esterco ou lodo de esgoto de cervejaria. Os teores de micronutrientes e metais pesados nas folhas da alface dos tratamentos n o diferiram daqueles observados no controle. Desses resultados depreende-se que o lodo de esgoto de cervejaria pode substituir o esterco de galinha em aduba es da cultura de alface, sem prejuízos na produtividade, qualidade e sem afetar os teores de metais pesados nas folhas.

Abstract: the teaching of philosophy to youngsters in school is justified if it teaches the creation of concepts that help them to solve their problems. there is no split between philosophy and philosophizing. the teaching of philosophy should be the production of philosophy as taught by philosophers; thus, the teacher of philosophy should be a philosopher. the teaching of the philosophic discipline in thought results in producing philosophic parameters which enable the youngster to create to himself and to the world in an original and autonomous way.

Mourning of professionals in a hematopoietic stem cell transplantation unit Luto de profissionais em uma unidade de transplante de células-tronco hematopoéticas
Renata Pereira Rodrigues,Renata Curi Labate
Ciência & Saúde , 2012,
Abstract: Introduction: The transplant of hematopoietic stem cells (HSCT) is a procedure that can either retrieve the patient's life or lead him/her to death. No avoiding death can bring to the professionals the experience of mourning and their limits. Objective: To understand the process of mourning experienced by health professionals who work in a HSCT Unit. Materials and Methods: This is a clinical-qualitative study with eight professionals from a HSCT Unit. Semi structured interviews were performed and the material was subjected to qualitative content analysis. Results: The results indicate that the professionals in a HSCT Unit experience the mourning when they observe slow processes of death and when the patient’s suffering becomes too intense. Conclusion: The process of mourning of the professional is still not recognized and there is little opportunity for public expression to facilitate the experience of mourning. Introdu o: O transplante de células-tronco hematopoéticas (TCTH) é um procedimento que pode tanto recuperar a vida do paciente quanto conduzi-lo ao óbito. N o conseguir evitar a morte pode trazer ao profissional à vivência do luto e de seus limites. Objetivo: Compreender o processo de luto vivenciado pelos profissionais da saúde de uma Unidade TCTH. Materiais e Métodos: Trata-se de um estudo clínico-qualitativo de 8 profissionais de uma unidade de TCTH. Foram realizadas entrevistas semidirigidas e o material foi submetido à análise qualitativa de conteúdo. Resultados: Os resultados indicam que os profissionais de uma unidade de TCTH vivenciam o luto quando verificam processos lentos de morte e quando o sofrimento do paciente se torna muito intenso. Conclus o: O processo do luto do profissional ainda n o é reconhecido e existe pouca oportunidade de express o pública para facilitar a vivência desse luto.

Abstract: gunnera perpensa (gunneraceae) is an african plant widely used in traditional medicine. this species is known for its activity involving the female reproductive system, such as inducing or increasing labor, treating female infertility, expelling the placenta and/or preventing post-partum hemorrhage. these properties are probably due to (z)-venusol, a majoritary compound, and its action in conjunction with substances in the whole extract and other natural products. in southern brazil, a native species gunnera manicata l. that also belongs to gunneraceae can be found. in spite of the traditional use of g. perpensa, there is no pharmacological and phytochemical information regarding the south american gunnera species. therefore, the aim of this study was to investigate the activity of brazilian g. manicata aqueous extracts on the reproductive system of immature female wistar rats through a uterotrophic assay and to verify the presence of (z)-venusol by liquid chromatography coupled with tandem mass spectrometry (lc-ms/ms). data were analyzed by analysis of variance (anova) and bonferroni′s post-hoc test (p< 0.01). results obtained shown that g. manicata extracts did not present in vivo anti or estrogenic activity. furthermore, (z)-venusol compound was not found. this study represents the first preliminary screening done on the south american g. manicata species.

Eccos Revista Científica , 2007,
Abstract: The present study analyses the contribution of the academic sector to community through a case study taking the Centro de Divulga o Científica e Cultural (Cultural and Scientific Diffusion Centre) as subject. This centre was set up in 1980, and since then, under the supervision of the University of S o Paulo in S o Carlos city, runs educational projects aimed at fostering school children interest for sciences. Differently from like initiatives, this centre endeavours to eschew patronising stances in favour of supportive actions. One of its project is the Experimentoteca , a collection of laboratory experiments which, upon request, are taken to schools for classroom demonstrations. Besides analysis of collated documents and facts within the country s educational scenario, this case is studied under the theoretical and methodological framework of the so called New History, which avails means to combine broad relations to singular descriptions.
