Paragenetic positioning of PGE in mafic and ultramafic rocks of Cabeço de Vide – Alter do Chão Igneous Complex

A expressão mineralógica de platinóides nas rochas máficas e ultramáficas de Cabeço de Vide (Complexo Ígneo de Alter do Chão), ocorre em dois episódios de deposição primária que se relacionam com os estádios de fraccionação dunítico a pós-dunítico (estibiopaladinite e froodite) e lherzolítico, equivalente ao início da fraccionação de sulfuretos (auricuprite e ouro). Os minerais tipomórficos subsequentes (sperrylite e arsenopaladinite) representam o reposicionamento epigenético associado à serpentinização.PGE mineralisation in mafic and ultramafic rocks of Cabeço de Vide (Alter do Chão Igneous Complex) results from two primary deposition events related to progressive fraccionation at dunitic to post-dunitic stage, represented by stibiopaladinite and froodite, and at lherzolitic stage, coupled by sulphide segregation, causing auricuprite and gold crystallization. Subsequent PGM (sperrylite and arsenopaladinite) must result from serpentinization repositioning

Geological mapping of the Cabeço de Vide basic-ultrabasic complex: essay on geometry and metalogenesis potential

A área detém as características mínimas necessárias ao desenvolvimento da prospecção de sulfuretos magmáticos primários e mineralizações de platinóides: litologias básicas e ultrabásicas e teores de Ni, Cu, Pt e Pd, anómalos. Na cartografia à escala 1:10 000 individualizam-se quatro domínios geológicos: litologias ultrabásicas, gabróicas, o domínio metassomático, e calcários do Câmbrico. O complexo básico e ultrabásico terá resultado de dois episódios de instalação ígnea, sendo o impulso ultrabásico anterior ao que originou os gabros.The area holds minimal characteristics that are needed to develop Magmatic sulphide deposits and PGE mineralization: basic and ultrabasic lithologies and anomalous Ni, Cu, Pt, Pd grades. It is possible to discriminate four geological domains based on 1: 10 000 mapping of the area: ultrabasic lithologies, gabbroic lithologies, metasomatic rocks and Cambrian limestones. The basic-ultrabasic complex might have resulted from two different magmatic pulses (the ultrabasic event preceding the gabroic pulse)

Gold in the Lousal mine, Iberian Pyrite Belt, Portugal

Recent exploration boreholes in the Lousal Mine, located within the Portuguese sector of the Iberian Pyrite Belt (IPB) yielded marked concentrations in gold/electrum in a section of core consisting of banded metasediments with massive pyrite. Preliminary research indicates that the gold is associated with native bismuth and bismuthinite and is clearly late in the paragenetic sequence occurring in fine chalcopyrite (± covellite)-bismuthinite-gold filled veinlets within the dominant and more massive pyrite. The pale yellow gold grains are fine, seldom reaching more than 6 ..m in length and half of that in thickness. EPMA results indicate that silver concentrations in gold grains can be as high as 27 wt.%. The results show similarities with conclusions drawn from the IPB on the Spanish side where gold of Co-Bi geochemical association is found as electrum with abundant to common Co and Bi minerals. These associated with pyrite and/or chalcopyrite are characterized by an abundance of sedimentary facies and show that the gold association formed at high temperature (>300 °C) during the initial phases of massive sulphide formation

Robotic4all project: Results of a hands-on robotic surgery training program

Objective: Although robotic surgery adoption and its indications are growing worldwide, for multiple factors, including costs, there is a lack of training and experience. Our aim was to study the impact of a robotic introduction training program on gesture performance, such as suturing, in robot-naive individuals. Methods: Using the DaVinci robot, a 2-hour program was based on virtual reality and anatomical model exercises. All participants performed 3 repetitions of virtual reality exercises on the virtual simulator, and then performed and were assessed on 2 tests, ie robot and laparoscopic training box. After the course, the participants were surveyed for this training program. Results: Twenty-seven residents and surgeons were enrolled in the training program. With only 2 hours of training, all of the participants were able to complete the training program, thus learning generic and specific skills in robotic surgery. In virtual reality exercise, the scores of the 3 exercises increased significantly with every repetition (p < 0.001) and the size of the increase was large. The completion time on the robot platform was 2.6 times faster (169.33 ± 28.28 s vs. 447.96 ± 156.55 s, p < 0.001) than that in the laparoscopic box, and the difference between both types of tests was large (p h 2 ¼ 0.797). The centralization and passage of the needle were significantly better on the robot platform (5 vs. 3, p < 0.001, r ¼ 0.47; 5 vs. 4, p < 0.001, r ¼ 0.59) than in the laparoscopic box. For the intracorporeal stitchþknot test, every participant was able to perform the exercise on the robot but only 85.2% (23/27) in the laparoscopic box. Twenty-one participants answered the survey, and 13 (61.9%) of them consid- ered robotic performance independent of laparoscopic experience. Conclusions: Surgeons are interested and seek training in robotic surgery. We implemented the first hands-on robotic surgery training program in Portugal and participants considered it was important and adequate for its purpose. All participants, even without robotic experience, learned quicker, performed better, faster and more precisely on the robot over laparoscopy

Influenza severe cases in hospitals, between 2014 and 2016 in Portugal

Rede Portuguesa de Laboratórios para o Diagnóstico da GripeBackground: Since 2009, the Portuguese Laboratory Network (PLNID) for Influenza Diagnosis has integrated 15 Laboratories in mainland and Atlantic Islands of Azores and Madeira. This PLNID added an important contribute to the National Influenza Surveillance Program regarding severe and hospitalized influenza cases. The present study aims to describe influenza viruses detected in influenza like illness (ILI) cases: outpatients (Outp), hospitalized (Hosp), and intensive care units (ICU), between 2014 and 2016. Methods: The PLNID performs influenza virus diagnosis by biomolecular methodologies. Weekly reports to the National Influenza Reference Laboratory ILI cases tested for influenza. Reports include data on detecting viruses, hospital assistance, antiviral therapeutics, and information on death outcome. Were reported during two winter seasons 8059 ILI cases,being 3560 cases in 2014/15 (1024 in Outp, 1750 Hosp, and 606 in ICU) and 4499 cases in 2015/2016 (1933 in Outp, 1826 Hosp, and 740 in ICU). Results: The higher percentage of influenza positive cases were detected in Outp in both seasons, 18% during 2014/15 and 20% in 2015/16. In 2014/15,influenza cases were more frequent in individuals older than 65 years old and these required more hospitalizations,even in ICU. In 2015/16,the influenza cases were mainly detected in individuals between 15-64 years old. A higher proportion of influenza positive cases with hospitalization in ICU were observed in adults between 45-64 years old.During the study period,the predominant circulating influenza viruses were different in the two seasons: influenza B and A(H3) co-circulated in 2014/15,and influenza A(H1)pdm09 was predominant during 2015/16. Even when influenza A is notthe dominant virus, A(H3) and A(H1)pdm09 subtypes correlate with higher detection rate in hospitalized cases (Hosp and UCI), with higher frequencies in adults older than 45. Influenza B,detected in higher proportion in outpatients, was frequently relatedwith influenza cases in younger age groups: 0-4 and 5-14 years old. Conclusions: This study highlights the correlation of theinfluenza virus type/subtype that circulates in each season with the possible need for hospitalization and intensive care in special groups of the population. Circulation of influenza A subtypes can cause more frequentdisease in individuals older than 45, with need of hospitalization including intensive care. On the other hand, influenza B is more frequently associated with less severe cases and with infection in children and younger adults. Influenza B circulation might predict lower number of hospitalizations.The identification of influenza type in circulation,byPLNID ineach season, could guide action planning measures in population health care.info:eu-repo/semantics/publishedVersio
