Perception of naturalness in materials and user’s choice: hardwood and melamine foil finished products

In this study we have sought to identify the existing relationship between materials perception of naturalness, and interviewee’s preferences between hardwood and low-pressure melamine foil MDF products. Prototypes of the same product were built in five different materials: ceramics, hardwood, polyethylene, wood-like décor melamine foil MDF, and aluminum. At first, 30 interviewees from ages 20-60, ranked samples of materials according to a) perceived degree of naturalness and b) preference (hedonic scale). After that, they identified the use of the product (prototype) and chose one, under the criteria of material adequacy. The results have shown that wood and its imitations are the materials perceived as most natural, and preferred by the interviewees. However, naturalness is not necessarily the deciding factor upon choosing a product

Dose calculation in Abdominal-Pelvic CT examinations from two hospitals in the Lisbon area

This work aims to evaluate whether the dose values received by patients submitted to Abdominal-pelvic Computed Tomography (CT) in two hospitals in the Lisbon area do agree with the Diagnostic Reference Levels. The dosimetric units of examinations performed with modulated and continuous current in both hospitals were also compared. The study consisted in collecting data from 200 abdominal - pelvic CT's, obtained in two hospitals (100 per hospital). In Hospital A, the mean DLP was 562.34 mGy.cm and the average values CTDIvol was 12.06 mGy. In Hospital B, the mean DLPand CTDIvol was 767.14 mGy.cm and 15.02 mGy, respectively. We have concluded that, from this sample, none of the dosimetric units values exceeded the Diagnostic Reference Levels values. It was also noted that tests performed in B involved higher doses of patient exposure to ionizing radiation

Quality of life of Brazilian plastic surgeons

Introduction: Medical quality of life (QoL) is an international object of study. Brazilian Plastic Surgeons QoL hasn`t yet been assessed, with few studies to perform any evaluation on the subject or estimate variables involved. Methods: This is a transversal, non-comparative, non-experimental, contemporary and of full selection study. An on-line research was performed between July and December in 2021, through the WHOQOL-bref questionnaire application, added with social-demographic information. The population will be composed of plastic surgery residents and surgeons associated with the Brazilian Society of Plastic Surgery (SBCP). Results: We obtained 168 answers via Google Forms®, which allowed us to determine our population through social- demographic questionnaire and make associations with the WHOQOL-bref findings. Conclusion: The current study identified correlations between sociodemographics and quality of life of the Brazilian plastic surgeon. We bring forward descriptive data on a subpopulation of responders inside the SBCP, which achieved a score positively higher than 50% in all of the questionnaire domains

Abordagem sobre bullying, drogas e violência com adolescentes na escola / Approach on bullying, drugs and violence with adolescents in school

A prevalência de violência, bullying e uso de drogas entre os adolescentes vem aumentando em todo o mundo, sendo necessária intervenções para sensibilizá-los sobre os assuntos, tendo na escola um ambiente ideal. O objetivo principal foi relacionar a incidência de bullying, uso de drogas e violência e as relações entre elas nas turmas do oitavo e nono ano de uma escola estadual e promover ações de prevenção. Nesse contexto, o presente trabalho realizou questionários sobre esses temas com alunos de 13 a 15 anos, e realizou palestras educativas, aplicando novamente os questionários para avaliar a validade da intervenção. Coletamos dados relevantes, 37% dos entrevistados relataram ter usado alguma droga, e 16% já foram agredidos, o que demonstram a estreita relação entre o uso de drogas e a violência, pontuada como bullying, entre os escolares, além de mensurar o consumo de substâncias entre eles e quais são elas. Além disso, foi promovida a saúde no ambiente escolar, com engajamento de alunos e professores.

Unexpected species diversity in electric eels with a description of the strongest living bioelectricity generator

Is there only one electric eel species? For two and a half centuries since its description by Linnaeus, Electrophorus electricus has captivated humankind by its capacity to generate strong electric discharges. Despite the importance of Electrophorus in multiple fields of science, the possibility of additional species-level diversity in the genus, which could also reveal a hidden variety of substances and bioelectrogenic functions, has hitherto not been explored. Here, based on overwhelming patterns of genetic, morphological, and ecological data, we reject the hypothesis of a single species broadly distributed throughout Greater Amazonia. Our analyses readily identify three major lineages that diverged during the Miocene and Pliocene—two of which warrant recognition as new species. For one of the new species, we recorded a discharge of 860 V, well above 650 V previously cited for Electrophorus, making it the strongest living bioelectricity generator. © 2019, The Author(s)

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.
