Evaluation of Paper Pulp Industry Waste as a Conductivity and Water Colour Reducer
Mourão, Paulo; Gomes, José; Branco, SaraThis work consists in exploring the preparation, characterisation and application of adsorbents based on lignocellulosic materials obtained from waste from the paper pulp industry, namely “Knots and Rejects - KR” and “Primary Sludge - PS”. These carbon materials were prepared by carbonisation under nitrogen flow, N2, and by chemical activation with the activating agent phosphoric acid, H3PO4. The materials were...
Stresses, friction, and wear on different materials and design for temporomandi...
Pinto-Borges, Henrique; Pinto, João; Carvalho, Óscar Samuel Novais; Henriques, Bruno; Silva, Filipe Samuel; Gomes, José; Ramos, AntonioThe purpose of the present study was to evaluate the coefficient of friction, wear volume, surface damage, and contacting stresses regarding different materials and condyle design for alloplastic temporomandibular joint total joint replacement (TMJ TJR). Spherical-and anatomical-shape condyle specimens were prepared from CoCrMo or Ti6Al4V alloys which were assessed against ultra-highly molecular weight polyethy...
COVID-19 cases and their impact on global air traffic
Sousa, Regina; Gomes, João Manuel; Gomes, José; Arcipreste, Mário; Guimarães, Pedro; Oliveira, Daniela Sofia Rijo; Machado, José ManuelThe air transport industry has marked unprecedented changes throughout the pandemic period of Covid-19 infection. Mostly in the number of flights canceled, liquidation of airlines and disconnection between points worldwide. The existing documentation relating to air traffic, in the specific period of this study, can be extracted, processed and visualized through tools widely used to support case study assumptio...
Major events that changed the instrumentalists’ performance
Travasso, Rui; Veiga, Pedro Alves da; Gomes, JoséThis article proposes to identify aesthetic currents and key events that affected music instrumentalists over the last 100 years - approximately - as well as to characterize new outcomes in music performance. The aesthetical, technical, and compositional evolution of music influenced and changed the traditional conception of the performance – that of a musician taking to the stage using only his instrument, per...
New aspects regarding the instrumentalists' performance
Travasso, Rui; Veiga, Pedro Alves da; Gomes, JoséThis article proposes to identify the aesthetic currents and key events that influenced music instrumentalists over the last century, as well as to characterize new outcomes in music performance. The aesthetical, technical, and compositional evolution of music impacted and changed the traditional conception of the performance – that of a musician taking to the stage using only his instrument in order to deliver...
A influência da média-arte digital no instrumentista e na performance: novos ca...
Travasso, Rui; Veiga, Pedro Alves da; Gomes, JoséO objetivo deste artigo é identificar e discutir a evolução impulsionada pelo uso das tecnologias digitais na performance musical instrumental. Limitamos o foco à performance musical de instrumentos identificados como pertencentes à família orquestral da tradição ocidental, de modo a auferir as repercussões, quer na performance, quer no instrumentista e considerando três aspetos chave da média-arte digital: int...
NOVAS TENDÊNCIAS NA SEGMENTAÇÃO TURÍSTICA: UM ESTUDO SOBRE MARKETING TERRITORIA...
Sousa, Bruno; Dieguez, Teresa; Gomes, JoséO turismo é uma atividade dinâmica e complexa do ponto de vista geográfico, visto que, cada vez mais, ele origina novos (e diferentes) segmentos de mercado com interesses individuais distintos. Esses segmentos são caracterizados pelas motivações que os fazem viajar e, por sua vez, pela diferenciação da oferta existente. Especificamente, o turismo cinematográfico tem-se afirmado, cada vez mais, como uma das ativ...

Adsorption of MCPA, 2,4-D and diuron onto activated carbons from wood
Cansado, Isabel; Mourão, Paulo; Gomes, José; Almodôvar, VitorActivated carbon adsorbents were produced from particleboard and medium-density fiberboard, industry originated wastes, without value added applications. These materials were characterized, showing a well-developed microporous structure reaching 0.58 cm3/g, and afterwards, their potential application for the removal of phenoxy acetic acids and substituted urea herbicide was evaluated. Studies in liquid phase we...
