This work has emerged from one of the core themes of research undergone in my masters' course at the Federal University of Minas Gerais - School of Nursing. In order to understand group learning, we used the theoretical references of Pichon-Riviére. According to this author, learning is an indicator of uttermost importance in group processes. Through process interactions, a learning mechanism u...

A distinction is drawn between psychoanalysis of the link and the link perspective of psychoanalysis. Pichon Riviere ́s notion of the internal group a notion which is lesser known and infrequently used would appear to be the theory which is most compatible with the latter of these perspectives. This approach requires a reformulation of the conception of the individual in relation to society and ...

Some endemic shrubs in arid and semiarid ecosystems are in danger of extinction, and yet they can play useful roles in maintaining or restoring these ecosystems, thus practical efforts are needed to conserve them. The shrubs Amygdalus pedunculata Pall., Amygdalus mongolica (Maxim.) Ricker and Ammopiptanthus mongolicus (Maxim. ex Kom.) Cheng f. are endemic species in arid and semiarid regions of...

The response of two stingless bees (Tetragonisca angustula and Melipona eburnea) to changes in vegetation cover was evaluated on seasonal spatial scales. Seasonal variation analysed for 15 months, with monthly melitopalinological assessments hives located three different covers: forests, fallows, grasslands, the Colombian Central Cordillera. Fallows, an intermediate disturbance degree, presente...

No clinical isolates have been reported for the recently described thermoactinomycete Kroppenstedtia eburnea. Between 2006 and 2011, we obtained 14 clinical isolates from patients in 9 U.S. states. Here we report growth characteristics, 16S rRNA gene sequencing, matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry-based identification, and antimicrobial susce...

The high-arctic Ivory Gull (Pagophila eburnea) has recently undergone a sharp decline in numbers, and in Canada it is listed as "Endangered" under the Species-At-Risk Act. To test for circumpolar genetic distinctiveness, we examined 264 bp of the mtDNA Control Region Domain I from 127 museum specimens collected during the breeding season from northern Canada, Greenland, and Norway, and during t...
