Edible coatings on the post-harvest conservation of orange Natal CNPMF 112.

Citrus fruit have a lengthy post-harvest lifetime, however owing to water loss, they lose firmness and luster on the skin after being picked. In light of the foregoing, this study aimed to assess the effects of coatings on the post-harvest conservation of ?Natal CNPMF 112? oranges under refrigerated settings using aqueous and alcoholic propolis extracts and carnauba wax. Fruit of ?Natal CNPMF 112? orange tree grafted on ?Rangpur? lime were treated with carnauba wax (100%) and alcoholic and aqueous propolis extracts (30%). The experimental design was totally randomized, with the plots consisting of the coatings plus the control (distilled water), and the subplots separated by the storage time (0, 10, 20, and 30 days) at 12 ºC ± 2, with the exception of weight loss, which was assessed at three-day intervals (0 to 30 days). Loss of fruit mass, average fruit mass, soluble solids, titratable acidity, ascorbic acid, maturity index, pH, and technical index were all examined. According to the findings, the alcoholic extract of propolis produced decreased fruit mass loss, a high maturity index, and balanced acidity. The coatings used in the postharvest conservation of refrigerated ?Natal CNPMF 112? oranges had no effect on the other parameters. As a result, propolis alcoholic extract is suggested for the preservation of ?Natal CNPMF 112? orange

Analysing interactions in a teacher network forum: a sociometric approach

This article presents the sociometric analysis of the interactions in a forum of a social network created for the professional development of Portuguese-speaking teachers. The main goal of the forum, which was titled Stricto Sensu, was to discuss the educational value of programmes that joined the distance learning model in Brazil. The empirical study focused on the sociometrie analysis of the social interactions that take place in asynchronous online environments. This approach, according to literature, allows for new means to observe, analyse, and interpret the reality of a new social paradigm. This type of analysis tries to understand the relationship established between the different actors, seeking to verify if the roles they play in both the access to information and the construction of shared knowledge. The data collected allow the researchers to deduce that the indicators used in the analysis are important for understanding and intervening in the dynamics and functioning of the network to propose improvements in its structure and organisation. In the specific case of the aforementioned discussion forum, the results of the sociometrie analysis of the perceived interactions were not surprising, considering that the nature of the topic did not demand deep reflection to contribute to the debate.This work is funded by Portuguese Foundation for Science and Technology under the doctoral grant SFRH/BD/60677/2009
