Intraoperative Neuromonitorization In Thyroid Surgery – A Qualitative Leap? Um ...
Mourão, Mariana; Guerreiro, Sofia; Crespo, Ana; Canberk, Sule; Tavares, Paula; Coutinho, José; Marques, Hugo Pinto Introduction: Identifying and preserving the recurrent laryngeal nerve is essential in thyroid surgery. Nerve Intraoperative Monitoring aids with this task and helps predict post-operative prognosis. Case Description: A 64-year-old male undergoes a Total Thyroidectomy with central and left lymphadenectomy for papillary thyroid cancer with intra-operative neuro-monitoring. Discussion: One of the most dread...
Silicon carbide diodes for neutron detection
Coutinho, José; Torres, Vitor J. B.; Capan, Ivana; Brodar, Tomislav; Ereš, Zoran; Bernat, Robert; Radulović, Vladimir; Ambrožič, Klemen; Snoj, LukaIn the last two decades we have assisted to a rush towards finding a He3-replacing technology capable of detecting neutrons emitted from fissile isotopes. The demand stems from applications like nuclear war-head screening or preventing illicit traffic of radiological materials. Semiconductor detectors stand among the stronger contenders, particularly those based on materials possessing a wide band gap like sili...
Silicon carbide neutron detector testing at the JSI TRIGA reactor for enhanced ...
Radulović, Vladimir; Yamazaki, Yuichi; Pastuović, Željko; Sarbutt, Adam; Ambrožič, Klemen; Bernat, Robert; Ereš, Zoran; Coutinho, José; Ohshima, TakeshiIn 2016, the NATO Science for Peace and Security Programme funded research project "Engineering Silicon Carbide for Border and Port Security" — E-SiCure was launched, its objective being the development of radiation-hard silicon carbide (SiC) based detectors of special nuclear materials (SNM), with the aim to enhance border and port security barriers. Detector prototypes based on SiC Schottky Barrier Diodes (SB...
Piezoelectric, ferroelectric, optoelectronic phenomena in hydroxyapatite by fir...
Bystrov, Vladimir; Coutinho, José; Avakyan, Leon; Bystrova, Anna; Paramonova, EkaterinaThe results are based on DFT calculations of hydroxyapatite (HAP) structures, pristine and defective, determined by various defects formed by Oxygen vacancy dependent on its charged states. Ordered hexagonal and monoclinic HAP phases have own spontaneous polarization, while disordered do not have it. These ferroelectric properties determined by orientation of OH dipoles provide piezoelectric and pyroelectric ph...

First record of the leafhopper Asymmetrasca decedens (Homoptera: Cidadellidae) ...
Coutinho, José; Amado, Carlos; Barateiro, Anabela; Quartau, José; Rebelo, TeresaAsymmetrasca decedens, a polyphagous leafhopper widely distributed in Mediterranean region, is here reported as a new record to mainland Portugal. Heavy infestations of this species have been found associated with peach, apricot and plum orchards, as well as on Alnus glutinosa, in southern of Serra da Gardunha (Beira Interior Region). Typical symptoms, the so-called ‘hopperburn', with leaves turning yellow and ...
Otimização da aplicação de fertilização azotada em trigos melhoradores
Costa, Maria Natividade; Rosa, Elizabete; Martins, P.; Espada, Rita; Boteta, Luis; Costa, Ana Rita; Pinheiro, Nuno; Gomes, Conceição; Bagulho, Ana SofiaO projeto FERTITRIGO - Otimizaçao da fertilização azotada em trigos melhoradores - foi desenvolvido na sequência de outros e tendo como base o conhecimento de que os principais fatores que influenciam a produção e a qualidade do grão de trigo são os genéticos (variedade), as condições climáticas e a as técnicas culturais, com destaque para a fertilização azotada.
Adsorption of H₂, O₂, H₂O, OH and H on monolayer MoS₂
Ferreira, Fábio; Carvalho, Alexandra; Moura, Ícaro J M; Coutinho, José; Ribeiro, R. M.Hydrogen and hydrogen-containing gases are commonly used as reductants in chemical vapor deposition (CVD) growth of MoS<sub>2</sub>. Here, we consider the defects resulting from the presence of hydrogen during growth and the resulting electronically active defects. In particular, we find that the interstitial hydrogen defect is a negative-$U$ center with amphoteric donor and acceptor properties. Additionally, w...
Alternância de herbicidas no controlo de infestantes do trigo
Barros, José; Coutinho, José; Costa, ArmindoNo ano agrícola de 2016/2017, realizou-se um ensaio de campo na Estação de Melhoramento de Plantas (Elvas), onde se estudou o efeito de vários herbicidas no controlo de infestantes em pré e pós-emergência na cultura do trigo (Triticum aestivum L.). O tratamento T1 (testemunha), foi o que menos grão e matéria seca total (grão + palha) produziu por unidade de área, consequência da maior competição com as infestan...
