Identification of apple fruit-skin constitutive laws by full-field methods usin...

The protective and preservative role of apple skin in maintaining the integrity of the fruit is well-known, with its mechanical behaviour playing a pivotal role in determining fruit storage capacity. This study employs a combination of experimental and numerical methodologies, specifically utilising the digital image correlation (DIC) technique. A specially devised inverse strategy is applied to evaluate the me...

Caracterização mecânica do material do ninho da vespa asiática

O ninho da vespa asiática (NVA) tem despertado o interesse de vários investigadores de diversas áreas do conhecimento. Na perspetiva da construção, este ninho revela uma complexidade funcional, arquitetónica, construtiva, estrutural e material deveras interessante. Alguns trabalhos de investigação foram publicados recentemente sobre o estudo desta construção animal. De uma maneira geral, estes trabalhos debruça...

Reputation, return and risk: A new approach

Corporate reputation has deserved attention in recent years from firms and researchers given its impact on creating a competitive advantage and on keeping a sustained superior performance. However, the impact of corporate reputation on risk, in addition to being less studied, still presents controversial results. Thus, the purpose of this study is to, simultaneously, analyze the effect of corporate reputation o...

Metamorfose no design alemão? Simplicidade no trabalho de Dieter Rams e Konstan...

O sucesso comercial e a visibilidade alcançada pelos produtos da Braun fizeram de Dieter Rams uma das principais figuras do design alemão. A abordagem racional, reforçada pelos seus Ten Principles for Good Design, parece corroborar o estereótipo de que o design alemão é caracterizado por uma tendência para a organização, sistematização e planeamento. Ainda que a sua prática aponte para uma direção consistente, ...

Recreational harvesting of the wedge clam (Donax trunculus) in southern Portuga...

This study was the first attempt to characterize the recreational harvesting of the wedge clam (Donax trunculus). For this purpose, 403 face-to-face interviews were performed in the summers of 2018 and 2019 in southern Portugal. The majority of the harvesters frequented the selected beaches during holidays and collected wedge clams as a hobby for an appetizer. The respondents reported an inter-annual variation ...

PADRES: Tool for PrivAcy, Data REgulation and Security

Experimental evaluation of cohesive laws components of mixed-mode I + II fractu...

Mixed-mode I + II fracture characterization of cortical bone tissue is addressed in this work. The mixed-mode bending test was used to impose different mode ratios. An equivalent crack length data reduction method was considered to obtain the strain energy release rate components. Crack opening and shear displacements were measured by means of digital image correlation. These quantities were then integrated to ...

Hybrid structures for Achilles' tendon repair

The management of extensive tendon injuries poses a considerable challenge. These cases typically require a partial replacement of the tissue, and conventional treatment options, either grafts or synthetic constructs, present disadvantages. Synthetic constructs may be produced with either non-biodegradable or biodegradable polymers. However, while the former lacks biointegration, the latter requires a compromis...

Torulaspora delbrueckii phenotypic and metabolic profiling towards its biotechn...

Wine is a particularly complex beverage resulting from the combination of several factors, with yeasts being highlighted due to their fundamental role in its development. For many years, non-<i>Saccharomyces</i> yeasts were believed to be sources of spoilage and contamination, but this idea was challenged, and many of these yeasts are starting to be explored for their beneficial input to wine character. Among t...
