Comunicação interpessoal em três assentamentos de reforma agrária de Unaí-Minas Gerais. Infoteca-e
ROCHA, F. E. de C.; ZOBY, J. L. F.; XAVIER, J. H. V.; GASTAL, M. L..
ABSTRACT: A research project on farming community development has been carried out by Embrapa Cerrados (Savannah Agricultural Research Center of the Brazilian Agricultural Research Corporation) in three Agrarian Reform Settlement Projects (PA): PA Jibóia, PA Paraíso and PA Santa Clara Furadinho, in Unaí country, Minas Gerais State, Brazil. At its initial phase, there was a diagnose and survey of information about the interpersonal interaction among group members. The objective of this article is to discuss the applicability of Moreno Sociometry in mapping the interpersonal relations between the land reform settlers to subsidize development of farming communities. initially, farmers were interviewed and requested to respond to three questions related to...

Intraerythrocytic organic phosphates and hemoglobins of skua - Catharacta maccormicki (Stercoraridae): at two different stages of the year in relation to Antartic migration BABT
Landini,Gustavo Fraga; Di Vito Neto,Alfredo; Schwantes,Arno Rudi; Schwantes,Maria Luiza Barcellos; Santos,Marcelo dos.
Catharacta maccormicki blood samples were collected in the winter (October) and in the summer (February) in order to study the intraerythrocytic organic phosphates, hemoglobin (Hb) electrophoretic patterns, oxygen blood equilibrium and stripped Hbs, as well as the effect of 2,3-biphosphoglycerate (BPG) and inositol hexaphosphate (IHP) on oxygen affinity. All the samples (five from the winter and five from the summer) showed the same electrophoretic pattern: one minor fast component and one major slow one. No differences in oxygen affinity and Bohr effect in the samples collected in the winter and in the summer were found. Oxygen affinity was higher in the stripped Hb than in the blood. BPG seemed to have no effect on the functional properties of skua Hb...

Purification of microbial b-galactosidase from Kluyveromyces fragilis by bioaffinity partitioning Rev. Microbiol.
Silva,Maria Estela da; Franco,Telma Teixeira.
This work investigated the partitioning of b-galactosidase from Kluyveromyces fragilis in aqueous two-phase systems (ATPS) by bioaffinity. PEG 4000 was chemically activated with thresyl chloride, and the biospecific ligand p-aminophenyl 1-thio-b-D-galactopyranoside (APGP) was attached to the activated PEG 4000. A new two-step method for extraction and purification of the enzyme b-galactosidase from Kluyveromyces fragilis was developed. In the first step, a system composed of 6% PEG 4000-APGP and 8% dextran 505 was used, where b-galactosidase was strongly partitioned to the top phase (K = 2,330). In the second step, a system formed of 13% PEG-APGP and 9% phosphate salt was used to revert the value of the partition coefficient of b-galactosidase (K = 2 x...
