Unlocking nature's potential: Modelling acacia melanoxylon as a renewable resou...
Ozkan, Sila; Sousa, Henrique; Gonçalves, Diogo; Puna, Jaime; Carvalho, Ana; Bordado, João; Santos, Rui Galhano dos; Gomes, JoãoThis study is focused on the modelling of the production of bio-oil by thermochemical liquefaction. Species Acacia melanoxylon was used as the source of biomass, the standard chemical 2-Ethylhexanol (2-EHEX) was used as solvent, p-Toluenesulfonic acid (pTSA) was used as the catalyst, and acetone was used for the washing process. This procedure consisted of a moderate acid-catalysed liquefaction process and was ...
O nemátode da madeira do pinheiro: novas abordagens de controlo e monitorização
Faria, Jorge MS; Cavaco, Tomás; Nunes, João C.; Gonçalves, Diogo; Vicente, Cláudia S. L.; Pires, David; Bonifácio, Luis; Inácio, Maria LurdesO nemátode da madeira do pinheiro é a maior ameaça para os povoamentos de pinheiro-bravo em Portugal. A investigação no INIAV aposta no desenvolvimento de novas estratégias de monitorização e biopesticidas para a sua contenção. O recurso a compostos naturais e a organismos antagonistas é o alvo de estudo de vários projetos de investigação no INIAV, por poder vir a ser uma estratégia de luta inovadora e um impor...

Short-term rentals and housing market: Evidence from portuguese metropolitan areas
Nobre, Francisco; Gonçalves, Diogo; Cruz, RonizeIn this paper, we make use of the rapid expansion of short-term rentals in Portugal, based on a policy change in 2014, to estimate the effects on house prices. Using a novel dataset consisting of property transaction data, from 2010 to 2017, for the metropolitan areas of Lisbon and Porto, we causally identify the impact of these reforms through a two-way fixed effects model, at the quarterly level, where we con...
Modelling of burnt pine heartwood acid-catalysed liquefaction
Ozkan, Sila; Gonçalves, Diogo; Paulo, Ivo; Queirós, Carla S. G. P.; Carvalho, Ana; Puna, Jaime; Gomes, João; Bordado, João; Santos, Rui Galhano dosThis study focused on bio-oil production by thermochemical liquefaction. For the reaction, the burnt pine heartwood was used as feedstock material, 2-Ethylhexanol (2-EHEX) was used as a solvent, p-Toluenesulfonic acid (pTSA) was used as a catalyst, and the solvent for washing was acetone. The procedure consisted of a moderate-acid-catalysed liquefaction process, and it was applied at three different temperature...
Synergistic Activity of Cymbopogon citratus and Mentha piperita Essential Oils ...
Gonçalves, Diogo; Cavaco, Tomás; Pombo, Ana; Moiteiro, Cristina; Teixeira, Dora Martins; Inácio, Maria L.; Faria, Jorge M.S.The pinewood nematode (PWN) Bursaphelenchus xylophilus is a major threat to pine forests. Research on sustainable pest management strategies is now a priority. Essential oils (EOs) are biodegradable, complex mixtures of volatiles that can show low toxicity to mammals and powerful nematicidal activities depending on their chemical composition. In the present work, the EOs of four plants were screened against the...
First report on the synergistic interaction between essential oils against the ...
Faria, Jorge M. S.; Cavaco, Tomás; Gonçalves, Diogo; Barbosa, Pedro; Teixeira, Dora Martins; Moiteiro, Cristina; Inácio, Maria L.Control of the pinewood nematode (PWN), the causal agent of pine wilt disease, can be achieved through the trunk injection of nematicides; however, many pesticides have been linked to environmental and human health concerns. Essential oils (EOs) are suitable alternatives due to their biodegradability and low toxicity to mammals. These complex mixtures of plant volatiles often display multiple biological activit...
On the 3D Reconstruction of Coastal Structures by Unmanned Aerial Systems with ...
Gonçalves, Diogo; Gonçalves, Gil; Pérez-Alvávez, Juan Antonio; Andriolo, UmbertoA wide variety of hard structures protect coastal activities and communities from the action of tides and waves worldwide. It is fundamental to monitor the integrity of coastal structures, as interventions and repairs may be needed in case of damages. This work compares the effectiveness of an Unmanned Aerial System (UAS) and a Terrestrial Laser Scanner (TLS) to reproduce the 3D geometry of a rocky groin. The S...
An evolutionary structural optimization algorithm for the analysis of light aut...
Gonçalves, Diogo; Lopes, Joel; Campilho, Raul; Belinha, JorgePurpose The purpose of the present work is to develop the combination of the radial point interpolation method (RPIM) with a bi-directional evolutionary structural optimization (BESO) algorithm and extend it to the analysis of benchmark examples and automotive industry applications. Design/methodology/approach A BESO algorithm capable of detecting variations in the stress level of the structure, and thus respon...
Development and In Vitro Validation of Antibacterial Paints Containing Chloroxy...
Querido, Micaela Machado; Paulo, Ivo; Hariharakrishnan, Sriram; Rocha, Daniel; Barbosa, Nuno; Gonçalves, Diogo; dos Santos, Rui GalhanoThe establishment of self-disinfecting surfaces is an important method to avoid surface contamination. Recently, paints with antimicrobial properties have been developed to be applied on different surfaces, avoiding contamination with pathogens. In this work, self-disinfecting paints containing Chloroxylenol (CLX), Terpineol (TRP), and a mixture of both substances were developed. The goal was to evaluate and va...
