Consulting project for TAP´s melhoria contínua area to increase operational efficiency at Lisbon HUB

The following report is destined to shortly describe the project developed under NOVA SBE’s Management Consulting Field Labs initiative. five NOVA SBE’s students for the airline company TAP on its melhoria contínua area. The objectives were to reduce TAP’s operational irregularities Minimum Connecting Time (MCT) in approximately 15 minutes at Lisbon Airport. In order to find the solution to the mentioned challenges the team adopted a practical work approach that proved to have a final positive impact in the company, namely the implementation of recommendations for operational irregularities would sav

Carcinoma adenóide cístico do pulmão : Adenoid cystic carcinoma of the lung

Introdução: O carcinoma adenóide cístico primário de pulmão é uma neoplasia torácica de crescimento lento e com malignidade de baixo grau. Representa 0,04 a 0,2% de todos os tumores pulmonares, sendo considerada uma neoplasia rara. Apresentação do caso: Paciente, sexo masculino, 49 anos de idade, foi admitido no Hospital Santa Casa de Misericórdia de Goiania, apresentando tosse persistente, dispneia, hemoptise e cerca de 4 episódios previos de pneumonia; negou comorbidades, etilismo e tabagismo, uso de medicamentos e alergias conhecidas. Discussão: O adenocarcinoma pulmonar possui como subtipo o carcinoma adenóide cístico. Anteriormente conhecido como cilindroma. Têm baixo grau de malignidade principalmente pelo seu lento crescimento e curso clínico estendido. Conclusão: Por se tratar de uma baixa malignidade, a sobrevida a longo prazo é satisfatoriamente prevista

Cisto cavum interpositum: Cavum interpositum cyst

Introdução: O velum interpositum (VI) é uma membrana no subaracnóideo formado por uma invaginação da pia-máter preenchido por líquido cefalorraquidiano (LCR). Sua formação ocorre durante o período embrionário e regridem posteriormente. A persistência dessa estrutura primitiva pode acarretar em sua dilatação, sendo denominado cavum veli interpositum (CVI) e, se maior que 10 mm em medida transversal axial, cisto cavum veli interpositum. Sua prevalência é maior em recém nascidos e prematuros. Apresentação do caso: paciente do sexo masculino, recém-nascido de 10 dias, foi admitido no Hospital Materno Infantil (HMI), por quadro de vômitos intermitentes, associado a febre de 39.5ºC. A mãe relata prematuridade de 31 semanas, trabalho de parto prolongado, cesariana e apresentação pélvica. RN teve um episódio convulsivo minutos antes da chegada à unidade. Nega outras queixas. A ressonância magnética destaca-se como exame padrão ouro, seguido da tomografia computadorizada de crânio. Discussão: Os cistos de CVI não apontam fisiopatologia e quadro clínico bem definidos, mas os conhecimentos acerca de sua localização são importantes para correlacionar sinais e sintomas neurológicos que condizem com efeito de massa, sendo um diagnóstico diferencial de lesões císticas intracranianas da linha média. A terapêutica ainda é restrita, mas há muitos relatos de casos em que a técnica de fenestração endoscópica minimamente invasiva foi preconizada para o tratamento dos cistos de CVI. Conclusão: Quanto ao prognóstico, em âmbito radiológico, estudos demonstram redução do cisto e do efeito de massa em imagem de ressonância magnética pós-operatória. E, apesar da resposta clínica ser dependente se os sintomas são decorrentes direta ou indiretamente do cisto, também demonstraram melhora nessa esfera

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
