[developing The Hospital's Mission To Facilitate Organizational Change: Limits And Possibilities].

The author begins by discussing the field of General Administration Theory vis-à-vis the defining role of organizational goals within an overall change process in organizations. While admitting the validity of some challenges raised by certain authors who deny the possibility of establishing a single direction for the organization by explicitly outlining its formal or official goals, the author presents and discusses his experience in defining the mission in the health sector as a way to implement organizational goals. This definition is meant as a strategy to improve communications among health team members and to a culture of responsibility when dealing with health service users.16973-8

Induction and growth curve of calli from leaf and nodal explants of genipap.

The aim of this study was to determine the effect of the auxin 2,4-D (2,4-dichlorophenoxyacetic) in calli formation from leaf and nodal segments of genipap and to characterize its growth curve. Explants obtained from shoots previously established from in vitro seedlings were used for calli induction. The experimental design was completely randomized in a 3x5x2 factorial with three accessions (NB, SA, SAL), five concentrations of 2,4-D (0.0; 2.0; 4.0, 6.0 or 8.0 mg L-1) and two times of measurement for calli fresh weight (30 and 60 days). There was callus formation in all treatments tested. It was observed that the best response for callus induction from leaf segments was with 2.0 mg L-1 of 2,4-D. For the nodal segment, the response among the accessions was different due to 2,4-D concentrations. The growth curve was plotted according to the fresh weight of callus obtained at intervals of 10 days up to 60 days. Through the established growth curve, the nodal-derived calli from accession SA should be transferred to a new medium, after 40 days of culture

Produção de alface (Lactuca sativa L.) fertirigada com solução contendo sólidos marinhos.

O presente trabalho teve por objetivo avaliar o efeito da utilização de soluções contendo sólidos marinhos (SM) sobre a produção de alface. Para isso, instalou-se uma estrutura de horta vertical confeccionada com caules de bambu em casa de vegetação, na qual se cultivou a alface cv. Baba de verão. Os tratamentos foram constituídos da aplicação de uma lâmina d´água de 2,85 ml dia-1 contendo soluções nutritivas nas concentrações de zero (testemunha), 0,0421, 0,1263, 0,2947 g L-1 de SM e tratamento adicional de 0,0421 g L-1 SM + 0,5% de urina de vaca. Aos 45 DAT foram determinados: o número de folhas, massa fresca da parte área, circunferência e altura do caule. A aplicação de soluções de SM promoveu redução do número de folhas e não afetou a circunferência da planta; as plantas submetidas à fertirigação com a solução SM mais concentrada apresentaram menor altura de caule e peso fresco
