A análise econômica complementa a avaliação da eficiência dos cultivos consorciados, considerando além da produção física das culturas, o preço dos produtos segundo sua classificação qualitativa e época do ano. Avaliou-se economicamente consórcios de alface crespa e pepino, em duas populações de plantas, no inverno-primavera, em casa de vegetação, em Jaboticabal, SP, Brasil. Foram calculados o custo operacional total (COT), a receita bruta (RB) e o lucro operacional (LO) das culturas do pepino e alface em monocultura e em consórcio. A mão-de-obra foi a componente com maior participação no COT das culturas em consórcio e monocultura. Maiores RB e LO foram observadas nos cultivos consorciados estabelecidos com o transplante da alface e do pepino no mesmo dia, independente da densidade populacional. Considerando-se o lucro operacional e o índice de uso eficiente da área, recomenda-se o cultivo consorciado com transplante da alface até 10 dias após o transplante (DAT) do pepino, com duas linhas, e ao 0 DAT do pepino cultivado com uma linha no canteiro

This dissertation try to understand how management actions implemented by Monsenhor Walfredo Gurgel Hospital in the city of Natal promote effectively the benefits of Home Care Services / Programa Melhor em Casa . The research is exploratory and descriptive, qualitative approach. Data were collected through document analysis and the interviews with the managers of the Program in Health Department and Hospital beyond the questionnaires with the home care teams and technical management unit of Hospital Jobs. The information were treatment trough categories that analyzed to implemented actions and program objectives. The results show that: the practices carried out by the host teams produce the humanization of care by seeking to ensure access to health services and solving human form; networks of health care are not yet finalized hindering the referral of patients to other units, the networks allow support from other institutions to minimize the problems encountered, the management unit vacancies allows the reduction of costs, mainly by regulating beds and record of health initiatives in home care assists in the monitoring and evaluation process of the Services Home Care / Programa Melhor em Casa primarily the epidemiological profile and patients individual treatment plan. Concludes that most of the actions implemented by the Hospital contribute to the effectiveness of the goals of Programa Melhor em Casa

Sperm cryopreservation success depends upon the maintenance of spermatozoa fertility potential. Sperm cells must preserve both integrity and functionality of several cell structures. The stabilization phase must allow the exit of water from the sperm cells via osmosis. This study aimed to compare the effect of refrigeration in the commercial refrigerator (CR) and the transport/refrigeration box (TRB) upon the viability of frozen bull sperm diluted in three different extenders (A, B and C). Ten Nellore bulls, Bos taurus indicus maintained in Artificial Insemination Center were used and the spermatozoa samples was assessed for Plasma Membrane Integrity and CASA evaluation. The stabilization phase (5 degrees C/4 hours) was performed in the CR as well as in the TRB, and then samples were exposed to nitrogen vapor during 20 minutes and then plunged into nitrogen. The statistical analysis was done using the variance analysis and the significance level was set at 5%. In the CR the post-thawing parameters for PM and ALH were higher (p < 0.05) in the extender A (glicine egg-yolk) and extender B (glicine egg-free) when compared with extender C (TRIS egg-yolk). As for BCF, STR and LIN, the parameters were higher (p < 0.05) in extender B than in C. Samples that were stabilized in the TRB presented higher post-thawing parameters (p < 0.05) for PM and LIN in extender A and extender B when compared with C. BCF and STR parameters were higher (p < 0.05) in extemder B when compared with C. Extender B samples had higher (p < 0.05) PMI when stabilized in CR. The findings in this experiment enable us to say that both CR and TRB were effective in keeping the viability of post-thawing bull semen.

Paspalum dilatatum is a valuable forage grass in the subtropics. This species consists of several sexual (tetraploid) and apomict (penta- and hexaploid) biotypes. It has been proposed that the presence of a genome of unknown origin, the X genome, is responsible for apomixis in penta- and hexaploid biotypes. Here we evaluated the utility of random amplified polymorphic DNA (RAPD) markers for discriminating sexual and apomictic P dilatatum biotypes. DNA samples from nine accessions, including P. intermedium, P. juergensh, and P dilatatum (ssp. flavescens, and the common and Uruguayan biotypes) were analyzed with 86 RAPID primers. Three hundred sixty-two fragments were scored and genetic similarity estimates revealed that the penta- and hexaploid biotypes were highly similar (S,, greater than or equal to 0.913). Forty RAPDs were unique to the penta- and hexaploid biotypes. Overall RAPID markers were useful for assessing genetic variation among closely related P dilatatum genotypes as well as generating putative X genome markers.

With the objective of evaluating the response of baru (Dipteryx alata Vog.) to nutrient limitation and to the different levels of fertilization, seven experiments were conducted. Experiment 1: Nutritional limitation in greenhouse. We employed 12 treatments in a completely randomized design with eight replicates. Experiment 2: Levels of liming and P in greenhouse. The experimental design was completely randomized in a factorial scheme with four levels of liming (V23.2% (natural soil), V45%, V65% and V85%) and four doses of P (0, 100, 300 and 500 mg kg -1 of P). Experiment 3: Doses of N in greenhouse. We used seven treatments (0, 75, 150, 225, 300, 375 and 450 mg kg -1 of N) in a completely randomized design. Experiment 4: Doses of K in greenhouse. We used seven treatments (0, 75, 150, 225, 300, 375 and 450 mg kg -1 ) in a completely randomized design. Experiment 5: Levels of liming under field conditions. We used four treatments (V6.7% (natural soil), V35%, V55% and V75%) in a randomized blocks design. Experiment 6: doses of P under field conditions. We used five treatments (0, 23.67, 53.34, 106.67 and 213.36 kg ha -1 of P 2O5) in a randomized blocks design. Experiment 7: Doses of N under field conditions. We used five treatments (0, 30, 60, 120 and 240 kg ha -1 of N) in Latin square. In greenhouse, the evaluations were conducted at eight months (for experiments 1 and 2) and 12 months (for experiments 3 and 4) after seeding, when the measurements of height and root collar diameter of the seedlings. Subsequently, the plants were harvested and separated into shoot and root system, for weighing and evaluating dry biomass gain. In the field, the evaluations were conducted at six, 12, 18, 24 and 30 months (for experiments 5 and 6) and at six, 12 and 18 months (for experiment 7). In these experiments, we evaluated the survival of the seedlings, height of the plants and diameter of the stem at soil height. The data obtained were submitted to analysis of variance, mean tests and regression analysis. In conclusion, during the phase of seedling formation, the species is little demanding in S and B, negatively responds to liming, positively responds to phosphate fertilization and does not respond to nitrogen and potassium fertilization. In the field, in general, the species does not respond to the application of P or to liming, and is negatively influenced by the application of elevated doses of nitrogen.

A presente pesquisa tem como objetivo investigar a dinâmica curricular implementada pelo Núcleo de Educação Popular Paulo Freire (NEP), da Universidade do Estado do Pará (UEPA), no contexto hospitalar, especificamente no Pavilhão São José; através da relação com o outro, a relação com o saber no cotidiano da relação pedagógica, as interpretações dadas ao currículo pelas docentes, as alterações de sentidos, do conhecimento e do saber, que contribuem, de forma concreta, para a inclusão e para a ação pedagógica em ambientes hospitalares. Os eixos teóricos que fundamentam esta investigação se voltam para os aspectos do conhecimento e construção do currículo e suas interfaces, mais diretamente a prática do currículo no cotidiano. Através da realidade curricular do Pavilhão São José, podemos conhecer o currículo adotado e interpretado pelas docentes nessa classe hospitalar e como essa proposta vem se materializando enquanto dinâmica curricular. Trabalhamos com a abordagem qualitativa aplicando no estudo de caso realizado no Pavilhão São José da Fundação Santa Casa de Misericórdia do Pará, no período de 2004 até junho de 2005. A coleta de dados foi feita através da entrevista com as duas professoras e a Coordenadora do Projeto de Ensino do NEP, análise documental, tendo sido privilegiados os questionários sócio-antropológicos realizados pelo NEP com os alunos-pacientes ou mães, fichas de atividades das docentes e o Projeto de Ensino do NEP. Os principais resultados apontam para a necessidade de valorização dessa ação educativa frente aos profissionais de saúde e pais, para que os alunos-pacientes a compreendam como caminho para sua escolarização; para os cursos de Formação de Professores reverem o tempo da ação educativa pelo "princípio da simultaneidade de eventos", pela partilha coletiva docente, pela orientação de currículos interdisciplinares e ampliação da cultura popular; para a forma grupal de problematizar os conteúdos articulados em classe, aumentar os relativos à escolarização, visto que essa proposta tem a pretensão de ofertar aos alunos-pacientes o acesso à escola; de buscar estratégias de interação entre os profissionais de saúde e educação; e investigar essa dinâmica curricular de forma mais sistemática e constante para desenvolver o processo educativo em ambiente hospitalar.
