Parametric design for additive manufacturing: Application in facade panels
Latorraca, Tássia; Teixeira, João; Jesus, Manuel; Brandão, Filipe Jorge Silva; Rangel, Bárbara; Guimarães, Ana Sofia[Excerpt] Introduction: The architectural and construction industry is undergoing transformative change driven by sustainability and effi ciency. Optimising its thermal performance is essential for buildings accounting for significant global energy consump tion. Among the most promising technologies addressing these challenges is 3D Concrete Printing (3DCP), which en ables the creation of customised, energy-eff...
Synthesis of thermoset elastomer from microbial oil derived from the fermentati...
Capeto, Ana Paula; Uribe, Braian Esneider Buitrago; Pintado, Manuela; Guimarães, Ana Sofia; Oliveira, Ana L. S.In the context of the 21st century, the integration of diverse perspectives within the circular economy framework, encompassing waste management, economic growth, and environmental sustainability, stands out as a paramount challenge. Addressing this challenge, an innovative avenue emerges through the application of microbial oil to replace traditional petroleum in the synthesis of essential commodity chemicals....
Building a greener future: Advancing concrete production sustainability and the...
Capêto, Ana Paula; Jesus, Manuel; Uribe, Braian Esneider Buitrago; Guimarães, Ana Sofia; Oliveira, Ana L. S.The integration of waste materials in extrudable cement mixtures has the potential to make the construction industry more sustainable by reducing carbon footprints and developing eco-friendly materials. This along with advancements in 3D concrete printing (3DCP) provides engineering and architectural benefits by reducing material waste and costs. In this paper, the impact of waste incorporation on properties of...
Fire-resistant bio-based polyurethane foams designed with two by-products deriv...
Capêto, Ana Paula; Amorim, Manuela; Sousa, Sérgio; Costa, Joana R.; Uribe, Braian Esneider Buitrago; Guimarães, Ana Sofia; Pintado, ManuelaThere is a growing interest in replacing conventional fossil-based polymers and composites with waste-based materials and fillers for environmental sustainability. This study designed water-blown polyurethane rigid foams using two by-products from the Amyris fermentation process of producing β-farnesene. The distillation residue (FDR) served as the main polyol component in the foam’s formulation (PF), supplemen...

O lugar da poesia nas orientações curriculares oficiais portuguesas
Azevedo, Fernando; Guimarães, Ana SofiaO artigo analisa o lugar da poesia nas diversas orientações curriculares oficiais portuguesas: no Currículo Nacional do Ensino Básico, publicado em 2001, no Programa de Português do Ensino Básico, que entrou em vigor em 2011, e nas Metas Curriculares de Português para o Ensino Básico, já em vigor. Os autores concluem que, apesar de a poesia constituir uma mais-valia para a criança, ao facultar-lhe, de modo natu...
The relevance of fiscal rules for fiscal and sovereign yield developments
Afonso, António; Guimarães, Ana SofiaWe assess whether numerical fiscal rules impact budget balances and sovereign yields. For a panel of 27 EU countries between 1990 and 2011, we find that fiscal rules reduce budget deficits, specifically expenditure rules, while countries with better fiscal rules experienced lower sovereign bond yields.
The relevance of fiscal rules for fiscal and yield developments
Afonso, António; Guimarães, Ana SofiaNumerical fiscal rules mitigate the bias of pro-cyclicality, as an alternative to discretionary measures conducted by policy makers. We assess whether fiscal rules impact budget balances and sovereign yields, and we perform a simulation exercise to compute debt developments of EU countries, assuming that they had implemented a numerical expenditure rule in 1990. Our panel analysis covers 27 EU countries between...
