The perception of Brazilians regarding these new protocols was identified through a quantitative survey with a sample of 412 Brazilian respondents, carried out between May and June 2021. As main results, sanitary and health protocols that do not affect their experiences on board were identified, as well as those protocols that compromised the experience perceived by the future traveler. The respondents’ propensity to travel on cruise ships and their perceptions about the influence of the ship size, the number of ports of call, nationalities on board, the number of guests, among other aspects, were also analyzed. Finally, in the final section of this paper, we presented an estimation of the expected number of cruisers for the 21/22 cruising season in Brazil, based on a kind Bayesian argument, considering different scenarios for the forthcoming season.展开更多

Kuntze exhibits dimorphism in its stem structure, where the trunk is orthotropic and branches and branchlets(primary and secondary branches) are plagiotropic. These stems exhibit different behavior when used for vegetative propagation,and only segments of trunk can form a complete plant. The physiological and biochemical mechanisms that characterize these stems are still little known. The aim of this study was to describe the free amino acid profiles in trunks,branches, and branchlets of A. angustifolia. Segments of 5 cm in length were excised from young individuals below the stem apex. The needles were removed and samples were frozen and lyophilized. The determinations were made by high-performance liquid chromatography, and the results were expressed as lg/g fresh weight(FW). The trunks and branches had the highest content of total amino acids, which were 112.23 ± 20.57 lg/g FW and 111.97 ± 27.78 lg/g FW, respectively. The amino acids—glutamine, aspartate and c-aminobutyric acid and tyrosine—were noticeably higher in the three types of stems.In the trunk, a higher amount of asparagine and tryptophan,was also detected. Glutamic acid and glutamine were found in higher quantities in the branches. The branchlets had very low total amino acid content (30.79 ± 4.19 lg/g FW), wherein asparagine is the only amino acid not detected. Thus, it was observed that the profile of the free amino acid differs among trunks, branches, and branchlets in A. angustifolia, indicating that they perform different functions.展开更多

From the beginning, there are biographical notes made about the most well-known fan leaders in Rio, such as Jaime de Carvalho, who founded the Charanga （1942）. The emergence of dissent among the fans, in the late 1960s, is then covered, which establishes itself within the organized fans in Rio with these individuals beginning to question the authority of the old fan group leaders. This is against the principle of giving unconditional support to the club and it is postulated that the fans have the right to criticize and protest against the club＇s management, even if this means using forceful tactics. Along with the journalistic narrative, there is a break-off by the ＂Young Fans＂ and a process of emancipation begins which occurs over the 1970s, this happens by means of the use of fan coaches and the invention of a lifestyle that is associated with soccer. Finally, the 1980s is marked by the constructive and destructive potential that is linked to fan groups. On the one hand, creating an Association of fans--Astorj--is pointed to in order to reach a mutual understanding, but it should be noted, on the other, that there are feuds, in a scenario of spiraling violence, in which fights, beatings, and even murders begin to be commonplace.展开更多
