Review of a Small-scale Pelagic Longline Fishery off Northeastern Brazil

The annual catches of four small longliners operating off northeast Brazil from 1983 to 1997 were examined across different areas and locations. The total catch comprised tunas (30%), sharks (54%), billfishes (12%), and other fish species (4%). Fishing strategy and annual composition of catches showed large spatial and temporal variabilities with the dominant catches alternating among yellowfin tuna, Thunnus albacares; gray sharks, Carcharhinus spp.; and blue shark, Prionace glauca. Catches of blue and gray sharks showed a significant interaction among seamounts, with gray sharks occurring in maximum abundance around those seamounts that had relatively deep summits and low-sloping depth profiles. Results are discussed in terms of the various factors that may have influenced distribution of effort

Tape Mbo'e: A First Experimental Assessment

The development of software not only needs to consider the construction process, but also other aspects such as cost, human resources and communication among stakehold- ers. The lack of simplicity into this context becomes explicit when some restrictions, such as service oriented architecture, must be considered as the basic style to build sus- tainable applications into environments were practitioners are not aware of this software technology. In addition to this, most of the available software processes are not directly applicable nor are they reusable, so learning times becomes risk for the development of the project. Therefore, Tape Mbo'e (TME) has been proposed to support the building of such applications, into development environments like developing countries where we can have economic constraints and scarcity of proficient practitioners. The first application of TME has been to develop a service-based application whose goal is to provide the interoperability among legacy systems of different public agencies in Paraguay. Initial results of this experience indicated the feasibility and simplicity of TME when applied in this field. The evaluation process, its results and conclusions are described in this paper

An Evidence-based Roadmap for IoT Software Systems Engineering

Context: The Internet of Things (IoT) has brought expectations for software inclusion in everyday objects. However, it has challenges and requires multidisciplinary technical knowledge involving different areas that should be combined to enable IoT software systems engineering. Goal: To present an evidence-based roadmap for IoT development to support developers in specifying, designing, and implementing IoT systems. Method: An iterative approach based on experimental studies to acquire evidence to define the IoT Roadmap. Next, the Systems Engineering Body of Knowledge life cycle was used to organize the roadmap and set temporal dimensions for IoT software systems engineering. Results: The studies revealed seven IoT Facets influencing IoT development. The IoT Roadmap comprises 117 items organized into 29 categories representing different concerns for each Facet. In addition, an experimental study was conducted observing a real case of a healthcare IoT project, indicating the roadmap applicability. Conclusions: The IoT Roadmap can be a feasible instrument to assist IoT software systems engineering because it can (a) support researchers and practitioners in understanding and characterizing the IoT and (b) provide a checklist to identify the applicable recommendations for engineering IoT software systems

Post-release mortality of shortfin mako in the Atlantic using satellite telemetry: preliminary results

This paper provides an update of the study on post-release mortality of the shortfin mako, Isurus oxyrinchus developed within the ICCAT Shark Research and Data Collection Program (SRDCP). Up to date, 34 tags (14 sPATs and 20 miniPATs) have been deployed by observers on Brazilian, Portuguese, Uruguayan, and US vessels in the temperate NE and NW, Equatorial and SW Atlantic. Data from 28 out of 34 tagged specimens could be used to obtain preliminary information regarding post-release mortality, resulting in a total of 7 mortality and 21 survival events.This study was carried out as part of a cooperative work conducted by the ICCAT Shark species group integrated in the ICCAT Shark Research and Data Collection Program (SRDCP). The authors are grateful to all fishery observers and longline skippers from the Nations involved in this study. Tags from additional sources have been contributed and deployed with several national Projects, specifically: Project "LL-Sharks: Mitigação das capturas de tubarões na pescaria de palangre de superfície (Ref: 31-03-05-FEP-44, funded by PROMAR)", Project "MAKO-WIDE - "A wide scale inter-hemispheric and inter-disciplinary study aiming the conservation of the shortfin mako shark in the Atlantic Ocean (Ref: FAPESP/19740/2014)", funded by FCT (Portuguese Foundation for Science and Technology) and FAPESP (São Paulo Research Foundation, Brazil), and Project SAFEWATERS SC7 (The provision of advice on the conservation of pelagic sharks associated to fishing activity under EU Sustainable Fisheries Partnership Agreements in the Atlantic Ocean) under the Framework Contract MARE/2012/21, funded by the European Commission.

West Nile virus infection in the golden hamster (Mesocricetus auratus): a model for West Nile encephalitis.

This report describes a new hamster model for West Nile (WN) virus encephalitis. Following intraperitoneal inoculation of a New York isolate of WN virus, hamsters had moderate viremia of 5 to 6 days in duration, followed by the development of humoral antibodies. Encephalitic symptoms began 6 days after infection; about half the animals died between the seventh and 14th days. The appearance of viral antigen in the brain and neuronal degeneration also began on the sixth day. WN virus was cultured from the brains of convalescent hamsters up to 53 days after initial infection, suggesting that persistent virus infection occurs. Hamsters offer an inexpensive model for studying the pathogenesis and treatment of WN virus encephalitis

A Novel Technique for Risk Calculation of Anastomotic Leakage after Thoracoscopic Repair for Esophageal Atresia with Distal Fistula

Purpose: This study was designed to determine the risk of anastomotic leakage after thoracoscopic repair for esophageal atresia by digitally measuring the length of the proximal esophagus and distance of carina to proximal esophagus. Methods: With the use of Picture Archiving and Communication System (PACS), the length of the proximal esophagus from the top of the first thoracic vertebra was measured on the preoperative chest x-ray, as well as the distance from the carina to the proximal esophagus. The chest x-rays of 27 neonates, born with esophageal atresia with distal fistula, were examined. Furthermore, the tapes from the procedures were reviewed. Statistical analysis was performed with the t test for equality of means by using SPSS® 12.0.1 for Windows. Results: Both groups were comparable, and there was a statistical significant difference in both length of the proximal esophagus (p<0.023) and distance of carina to proximal esophagus (p<0.022) in patients who did and did not leak postoperatively. There seems to be a tendency toward a shorter proximal esophagus in recent years that was not obvious earlier. Conclusions: The digital measurement of the length of the proximal esophagus (M<7 mm) and distance of carina to proximal esophagus (M<13.5 mm) with the use of PACS gives a good risk calculation for postoperative leakage
