An indirect way to measure the speed of bottom currents may be using granulometric parameters such as the proxy sortable silt (). This proxy is associated with the sedimentation process and can estimate paleocurrents. This study aims to evaluate the range of the near-bottom current flow speed through the and related to oceanographic processes in the southeastern Brazilian continental slope. The values ranged from 17.08 to 26.23 µm, presenting a mean value of 19.87 µm. The flow speed values were obtained through Ledbetter's (1986) and Miller's (1977) formulas, varying from a minimum of 0.07 and 0.21 m s-1 to a maximum of 0.26 and 0.24 m s-1. The changes in bottom velocities observed in the Campos Basin are influenced by geomorphologic and hydrodynamic parameters, namely the off-shelf export of the sediment; the action currents (Brazil Current, Intermediate Western Boundary Current, and the Deep Western Boundary Current); and the geomorphological characteristics (island, ravine, and halokinesis movement).
The present study sought to analyze the impacts that the pandemic context generated on the mental health and subjectivity of women who worked on the front lines of Covid-19, understanding the material and subjective conditions to which these workers were subjected.The methodological procedure used in this research is qualitative and exploratory.Seven individual interviews were conducted with a semi-structured script, containing open and closed questions.Regarding the profile of the participants, they had an average age of 49 years, self-declared white, with formal employment, belonging to a high socioeconomic level and had a high level of schooling.The collected data were analyzed under the precepts of hermeneutic-dialectic analysis, with the formation of five categories of analysis to facilitate the identification of shared meanings and own meanings expressed in the speeches.With regard to the results, the interviewees verbalized about the intense workday, the reconciliation between the domestic sphere and the productive sphere, the fear of contamination and transmission of the virus, the feeling of impotence in the face of deaths, the feeling of loneliness in relation to some family members and friends and the presence of solidarity among the professional teams.That said, it was noted that, although they belonged to a high social class and were supported by the institutions in which they worked, the pandemic situation generated psychic and physical suffering in the women in question.
Objective To evaluate bone development in patients with alveolar clefts and permanent dentition treated with alveolar bone graft supplemented with stromal vascular fraction (SVF). Design Clinical, prospective, randomized. Location Single tertiary care institution. Patients Eighteen participants with unilateral alveolar cleft and permanent dentition were included. Patients with other comorbidities were excluded. Intervention The control group underwent alveolar bone grafting (ABG) using iliac crest bone, while the experimental group underwent the same treatment, supplemented with SVF. Adipose tissue was collected by abdominal liposuction, and the SVF was processed using mechanical methods (decantation, microfragmentation, and filtration). Main Outcome Measurement Bone formation and bone graft integration rate in alveolar cleft at 6 months postsurgery using 3-dimensional tomographic methods and density measurements. Results The amount of bone graft correlated with an improvement in the relationship between the cleft and noncleft sides (R = 0.78, P < .001) and an improvement in alveolar cleft density (R = 0.69, P = .005), but did not correlate with the graft integration rate. The experimental group showed larger cleft sizes (0.83 × 1.74 cm 3 , P = .021) and older patients (17.35 × 27.6 years, P = .002), and did not differ in terms of bone development variables when compared to the control group. Conclusion ABG supplemented with SVF showed statistically similar bone development results, but with a better trend than conventional ABG. Additionally, the studied groups had asymmetric pre-existing characteristics, with greater severity in the experimental group. A larger study will be necessary to mitigate preoperative characteristic differences and to more accurately compare the results between the methods.
As the urgency to evaluate the impacts of climate change on marine ecosystems increases, there is a need to develop robust projections and improve the uptake of ecosystem model outputs in policy and planning. Standardising input and output data is a crucial step in evaluating and communicating results, but can be challenging when using models with diverse structures, assumptions, and outputs that address region-specific issues. We developed an implementation framework and workflow to standardise the climate and fishing forcings used by regional models contributing to the Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) and to facilitate comparative analyses across models and a wide range of regions, in line with the FishMIP 3a protocol. We applied our workflow to three case study areas-models: the Baltic Sea Mizer, Hawai’i-based Longline fisheries therMizer, and the southern Benguela ecosystem Atlantis marine ecosystem models. We then selected the most challenging steps of the workflow and illustrated their implementation in different model types and regions. Our workflow is adaptable across a wide range of regional models, from non-spatially explicit to spatially explicit and fully-depth resolved models and models that include one or several fishing fleets. This workflow will facilitate the development of regional marine ecosystem model ensembles and enhance future research on marine ecosystem model development and applications, model evaluation and benchmarking, and global-to-regional model comparisons.
Mammals are threatened worldwide, with ca. 26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated to habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information on their distribution is crucial to delineate and support conservation actions. MAMMALS IN PORTUGAL is a publicly available data set compiling unpublished geo-referenced occurrence records of 92 terrestrial, volant and marine mammals in mainland Portugal and archipelagos of Azores and Madeira that includes 105,026 data entries between 1873 and 2021 (72% of the data occurring in 2000 and 2021). The methods used to collect the data were: live observations/captures (43%), sign surveys (35%), camera trapping (16%), bioacoustics surveys (4%) and radio-tracking and inquiries that represent less than 1% of the records. The data set includes 13 types of records: 1) burrows | soil mounds | tunnel, 2) capture, 3) colony, 4) dead animal | hair | skulls | jaws, 5) genetic confirmation, 6) inquiries, 7) observation of live animal, 8), observation in shelters, 9) photo trapping | video, 10), predators diet | pellets | pine cones/nuts, 11) scat | track | ditch, 12) telemetry and 13) vocalization | echolocation. The spatial uncertainty of most records ranges between 0 and 100 m (76%). Rodentia (n = 31,573) has the highest number of records followed by Chiroptera (n = 18,857), Carnivora (n = 18,594), Lagomorpha (n = 17,496), Cetartiodactyla (n = 11,568) and Eulipotyphla (n = 6,400). The data set includes records of species classified by the IUCN as threatened (e.g., Oryctolagus cuniculus (n = 12,159), Monachus monachus (n = 1512), and Lynx pardinus (n = 197)]. We believe that this data set may stimulate the publication of other European countries data sets which would certainly contribute to ecology and conservation-related research, and therefore assisting on the development of more accurate and tailored conservation management strategies for each species.
