Management of estuarine beaches on the Amazon coast though the application of recreational carrying capacity indices

The purpose of this paper is to determine the Recreational Carrying Capacity of three estuarine beaches (Colares, Marudá and Murubira) on the Amazon coast of Brazil, based on the combined assessment of natural conditions and visitor facilities. In the final analysis, the carrying capacity of Colares beach was estimated to be 1089 visitors per day, and that of Murubira beach, 238 visitors per day. At Marudá beach, however, the inadequate quality of the water resulted in an RCC of zero, indicating that the beach should not be visited for recreational use. The results of this study may provide a valuable diagnostic tool for the development of future state and municipal coastal management programs. We believe that the procedures adopted in this study are applicable to other estuarine beaches on the Amazon coast, as well as in other estuarine beaches elsewhere with similar natural characteristics.Peer ReviewedPostprint (author's final draft

On the r−r-stability of spacelike hypersurfaces

In this paper we study the strong stability of spacelike hypersurfaces with constant $r$-th mean curvature in Generalized Robertson-Walker spacetimes of constant sectional curvature. In particular, we treat the case in which the ambient spacetime is the de Sitter space

A Mobile App to Manage Children Dental Anxiety: Context and Approach

Anxiety and fear related to dentistry interventions have been identified as problems affecting children. This reduces their quality of life and may have a negative impact on aspects such as sleep, self –esteem, mood, social relationships, and other psychological issues.The ARCADE project aims to design and develop a technological solution to manage children dental anxiety. This solution consists on a mobile system co-designed with children. An ecological momentary intervention is proposed using this solution before, during and after dentistry treatments. This paper presents a methodological approach to develop the project

Seasonal variation in the diet of Lontra longicaudis in the Paraná River basin, Argentina

We studied the Neotropical otter ( Lontra longicaudis ) seasonal diet variations in the middle Paran á River valley, in central-northern Argentina, at the southern limit of its global range. We recorded 745 prey items in 320 scats collected over the course of 1 year in a tributary stream of the Paran á River. Fish, crustaceans, mammals, and insects were the most important items in frequency of occurrence among items. Other items, like mollusks, birds, amphibians, and reptilians were presented in low frequency in all seasons. We recorded seasonal variation in the frequency of the principal categories items: fish, mammals, crustaceans, and insects and in reptilian that had low frequency. Although fish were the most common items consumed by the otter, other groups such as crustaceans, mammals, and insects, were also important in the diet of the Neotropical otter throughout the seasons. Mammals and insects showed a higher frequency in the Neotropical otter diet in our study than in Brazil, Mexico, and even northern Argentina. We noted a marked variation throughout the Neotropical region in the niche breadth indices among studies of Neotropical otter ’ s diet. The Shannon H ′ diversity index showed a higher value in our study than in most of previous diet analyses of this species.Fil: Vezzosi, Raúl Ignacio. Provincia de Entre Ríos.

Atos Poéticos Performativos no Chão de Tupinambá

O artigo nasce de pesquisa em andamento no PPGArtes (Doutorado interinstitucional) da Escola de Belas Artes da UFMG, sobre o ato poético performativo realizado por Tereza de Colares, no Chão de Tupinambá, em Colares-Pará, utilizando o Chá Sagrado com a Ayahuasca. Segue-se a busca de uma cartografia poética no campo das artes da cena, desenhada em práticas orais, corporais e improvisações performativas, junto às experiências de traço xamânico de Tereza de Colares
