Análise das respostas de atributos sísmicos dos carbonatos barremiano, albiano e neógeno no campo de Bonito, bacia de Campos - RJ

The Bonito oil field, located on southwest of Campos Basin-RJ, has been explored since 1982. The main reservoir is composed by calcarenites of Quissamã Formation (Macaé Group) from Albian, but two other carbonate levels are present on the field, firsts is Coqueiros Formation (Aptian) and the second Siri Member (Oligo-Miocene). In this context and considering that carbonates reservoirs are a challenge for exploratory geoscientists, since the difficulty on recognize the effective reservoir distribution. This work aim to characterize the geophysical/geological facies based on seismic attributes responses, related to reservoir geometrical distribution, for the tree carbonates intervals on Bonito oil Field. A tree dimensional interpretation of the levels has been developed, based on well cross correlation and a 3D seismic interpretation, resulting on the stratigraphic and structural framework of the field, which showed a NE-SW fault trend controlling the Aptian carbonates reservoirs, and halocnetics structures showing a structural trap on Albian carbonates reservoirs. The definition of the structural/ stratigraphic framework possibly the seismic attributes calculations over the reservoir intervals. To select the best response in comparison with the reservoir distribution, obtained by seismic interpretation, the attributes response were compared with isopachs maps of each carbonate stratigraphic level. The attributes Maximum Amplitude, Maximum Magnitude and Rms Amplitude showed a good answer to reservoir distribution. The Rms Amplitude also showed a good correlation with physical rock properties, like RHOB bulk density, for the Albian and Aptian carbonates, as consequence it is possible make a characterization of reservoir distribution based on seismic attribute answer

Defensive strategies of neonate nurse sharks, Ginglymostoma cirratum, in an oceanic archipelago of the Western Central Atlantic

Two defensive tactics of neonates of nurse sharks, Ginglymostoma cirratum, are reported based on underwater observations. Described as "hiding behaviour" and "substrate resemblance", the defensive strategies were categorized according to the predominant habitat in which the individuals were found and to the behaviour displayed by the sharks in the presence of the observer. In structurally more complex habitats with a wide availability of shelters, the preferential behaviour displayed by neonates is to hide inside holes or crevices. When in open areas deprived of refuges, neonates tend to resemble arborescent coverings as seaweed banks or colonies of octocorals, which allows the use of more exposed habitats without increasing the susceptibility of capture by predators. Both aspects are relevant for a better understanding of the behaviour of neonates of G. cirratum and have important implications for identifying important habitat in nursery areas, and also for the management of this vulnerable species off South America.

Shark Attacks and Shark Diving Reply

It is with great astonishment and concern that I read the letter to the editor by Barreiros et al1 in which the authors report an attack by a blue shark on a spear fisherman in the Azores. Whereas the first part of the article accurately details the circumstances of the accident, Barreiros et al, in the second part, devise a far-fetched and illegitimate connection with shark diving, in particular with shark feeding.

Fatores ergonômicos críticos de mochos odontológicos e sua relação com a produtividade e satisfação de cirurgiões dentistas

The purpose of the ergonomics is to generate adequate working conditions, by the correct use of equipment and appropriate anatomic positions. Ergonomics has become essential in the dentist's life while in the dental practice. The misuse of equipment in performing tasks or the wrong choice of equipment can initiate various problems like back pain, bursitis, repetitive strain injury (RSI), limitation of movement, and stress. Using a survey that was implemented with professional dentists linked to Paulista Association of Dental Surgeons (APCD) and graduate students at the Universidade Estadual Paulista (UNESP) in the São José dos Campos (SP) region, this study intends to propose an adequate research instrument to identify ergonomic critical factors of dental stools and their relation to productivity and satisfaction of dentists. The survey was developed with Google Docs Forms tool and was designed by analysis of other studies, existing surveys and other papers in this area. Relevant content were discussed and developed questions about the stool used by dentists in their activities, the occurrence of any problems arising from the exercise of their profession and the views of respondents about the influence of using the dental stool in these cited problems as well as their productivity. Due to obstacles encountered during the project, particularly bureaucratic issues, the survey cannot be implemented as needed, resulting in a test with reduced number of answers. The users' opinion varies according to the stool used, bringing some difficulty to generalizing the answers, but if treated properly, it is possible to obtain relevant conclusions about the main aspects perceived by users in relation to the stool and the needs pointed as most important
