Severe Injuries of Former Portuguese Football Players: a Post-Career Burden?

: Background/Objectives: Football players have a high injury risk due to the physical demands of their profession, which can negatively affect their quality of life (QoL) in the long term. The aim of this study is to characterize the severe injuries that former Portuguese football players suffered throughout their professional careers and investigate the resulting impacts on the physical domain of QoL after ret...

The professional careers of former portuguese football players: a sociodemograp...

Introduction: The study is aimed to identify sociodemographic and professional characteristics related to the careers of former Portuguese football players. Methodology: The sample consisted of 84 Portuguese former players (48.8 ± 8.2 years old) with at least 8 years of professional experience, who finished their careers between 1988 and 2018. Quantitative data was collected from a validated semi-structure inte...

Contributos para a análise sociológica dos espaços azuis

reflexão em torno da problemática dos espaços azuis. Por ora sabemos, da literatura exploratória consultada, que existe uma perspetiva otimista sobre tais espaços, onde a água assume uma certa centralidade nas dinâmicas da ordem local social, económica, cultural e política. Assim, num primeiro momento, colocamos em debate as perspetivas concetuais sobre os espaços azuis, questionando a especificidade dos mesmos...

Durable and breathable ZnO/graphene-coated fabrics for enhanced BQR protection

This work developed a new strategy to create active protection against chemical, biological, radiological and nuclear (CBRN) threats, based on polyurethane-based coatings for outer (water and oil-repellency) and inner (CBRN protection) functionalization of fabric. The internal coatings were functionalized with varying concentrations of zinc oxide nanoparticles (ZnO) and/or graphene nanoplatelets (Gf) and carefu...

Microsatellites reveal high levels of genetic admixture in the natural populati...

Laurus (Lauraceae) species are currently restricted to isolated refugia in the southern Black Sea, Mediterranean Basin, southern Morocco, and Macaronesian archipelagos. One to three species of Laurus has been recognized: the Azorean endemic Laurus azorica, L. nobilis from the Mediterranean, and L. novocanariensis from Madeira and the Canary Islands. This study aims to determine the population structure, genetic...

The Quality of Life of Former Portuguese Football Players

Background: The demands of playing professional football can have an impact on an individual’s quality of life (QoL), which may remain into retirement. Given limited evidence exists regarding the QoL in former football players, this study aimed to assess QoL among Portuguese former players according to career duration, career end period, competitive level, tactical-positional status, international status, acade...

On the enhancement of material formability in hybrid wire arc additive manufact...

This paper is focused on improving material formability in hybrid wire-arc additive manufacturing comprising metal forming stages to produce small-to-medium batches of customized parts. The methodology involves fabricating wire arc additive manufactured AISI 316L stainless steel parts subjected to mechanical and thermal processing (MTP), followed by microhardness measurements, tensile testing with digital image...

Joining by forming of bi-material collector coins with rotating elements

This paper presents a novel manufacturing process for producing innovative bi-material collector coins with free- rotating inner elements. The inner elements are fabricated using additive manufacturing, enabling the creation of coins with complex and intricate geometric details that would be unattainable using conventional wrought materials. The outer elements (rings) are metallic, and this study addresses the ...
