Autobiographical Memory Specificity and the Role of Defensiveness, Brooding, Executive Control, and Family Functioning
The aim of this study was to examine the importance of defensiveness, tendency to brood, cognitive complaints and family functioning in the generation of specific autobiographical memories among a clinical sample of diagnostically diverse adult outpatients. Adults who report more defensiveness, more proneness to brood, more cognitive complaints and were raised by more dysfunctional families were hypothesized to elicit fewer specific memories. Further, trauma history and depressed mood were also explored. To explore these questions, I use data collected from eighty-eight adults. Pearson correlation is used to analyze the relationship between memory specificity and defensiveness, likelihood to brood, cognitive complaints and family functionality. Multiple regression analysis is used to explore whether the relationship between the previously mentioned variables depends on depressed mood. The results indicate:(1) patients who are more defensive have fewer specific memories, (2) the relationship between proneness to brood and memory specificity depends on mood; whereas non-depressed ruminators retrieve more specific memories, depressed ruminators retrieve fewer negative specific memories, (3) the relationship between cognitive complaints and memory specificity also depends on mood; whereas non-depressed patients who report more cognitive complaints retrieve more specific memories, depressed patients who report more cognitive complaints retrieve fewer specific memories, and (4) patients raised in less dysfunctional families retrieved more negatively overloaded specific memories. Further, there is no difference in memory specificity retrieval between traumatized and non-traumatized groups. In conclusion, being in contact with emotions allow patients to retrieve more specific memories. However, when the patient is depressed, an increased difficulty in controlling affect by being “stuck” in rumination or by feeling unable to think or concentrate impairs the ability of retrieving specific memories
Características morfológicas do sequestro pulmonar
ABSTRACTThe pulmonary sequestration corresponds to pulmonary tissue intra or extra-lobar with systemic arterial nutrition and collateral bronchial ramification. It is unfrequent and the intra-lobar identification depends on the correct clinical signs and morphology.The correct study includes imagiologic identification of the systemic artery and morphological characterization of parenchymal changes. These allow identification of abnormal pulmonary parenchyma in intra-lobar cases and were observed using histochemical and imunohistochemical routine methods, both in intra and extra-lobar cases. Four cases of intra-lobar sequestration and four cases of extra-lobar sequestration were studied with application of histochemical technics – Movat’s pentachrome stain and Verhoeff – and immunolabelling with CK7 and TTF1.The parenchymal inflammatory distortion by colagenization was constantly seen as was BALT hyperplasia and pleuritis.By using Movat’s pentachrome stain we characterized the sequestration by identifying the artery and the parenchymal changes.The CK7 was usefull in the identification of parenchymal damage, together with the antibody anti-TTF1 that had a variable expression, stronger in areas of inflammation because of PII hyperplasia.REV PORT PNEUMOL 2003 IX (2): 153-16

Mortality due to respiratory infections: an alert study before COVID-19 pandemic
Objective. Respiratory tract infections remain a common problem in clinical practice with high morbidity and mortality worldwide. In Portugal, pneumonia was the third leading death cause in 2018. Due to COVID-19 pandemic, there is a growing concern about the burden of respiratory diseases and preventable risk factors. The present study started before the pandemic and its aim was to determine the occurrence of pneumonia/bronchopneumonia in a postmortem series and to characterize its circumstantial context.
Methods. A retrospective anatomopathological study was performed on cases with acute pneumonia/bronchopneumonia at the Medicolegal Portuguese Institute (2011-2017).
Results. In an autopsy series of 737 patients, 521 were male and 675 presented comorbidities. The mean age was 63.87 ± 19.8 years. The most common acquisition site was community (65.1%), as natural death (65.5%). Concerning the manner of death, most cases (48.0%) were sudden deaths, followed by accidents (29.2%). A statistically significant association was observed between the medicolegal etiology and the place of infection acquisition, with higher prevalence of natural obitus (91.0%) in community-acquired pneumonia/bronchopneumonia versus higher prevalence of violent obitus in hospitalacquired pneumonia/bronchopneumonia (82.1%) (p < 0.001).
Conclusions. Forensic anatomopathological postmortem data may contribute to better understand community and hospital pulmonary infections.info:eu-repo/semantics/publishedVersio
Low-Density Cardoon (Cynara cardunculus L.) Particleboards Bound with Potato Starch-Based Adhesive
In the present work, and for the first time, totally biosourced low-density particleboards were produced using cardoon particles (a no added value by-product from the Portuguese cheese making industry), bound with a potato starch adhesive. Different starch/cardoon ratios (0.6, 0.8, 1 and 1.2) were tested and the effect of different bio-based additives (chitosan, wood fiber and glycerol) on the performance of the adhesive system was evaluated. The best result was obtained for a formulation with a starch/cardoon mass ratio of 0.8, a chitosan/starch mass ratio of 0.05 and a water/starch mass ratio of 1.75. The particleboards produced had a density of 323 kg·m⁻³, internal bond strength of 0.35 N·mm⁻² and thickness swelling of 15.2%. The values of density and internal bond strength meet the standard requirements of general-purpose lightweight boards for use in dry conditions according to CEN/TS 16368 specification. Moreover, the susceptibility of the formulations with best results was established against subterranean termites and one decay fungi.Laboratory for Process Engineering, Environment, Biotechnology and Energy (UIDB/00511/2020); FCT/MCTES (PIDDAC); North Portugal Regional Operational Programme (NORTE 2020), under the Portugal 2020 Partnership Agreement, through the European Regional Development Fund (ERDF) (NORTE-01-0145-FEDER-000005); Centre Portugal Regional Operational Programme (CENTRO 2020), under the Portugal 2020 Partnership Agreement, through the European Regional Development Fund (ERDF) (CENTRO-01-0246-FEDER-000003).info:eu-repo/semantics/publishedVersio
Analytical Hierarchy Process for Risk Management in the Stabilized Flight Approach - Expert Judgment
Destabilised approaches have been the primary cause of fatal accidents during the approach and landing phase, as stated in (Airbus, 2023). The stabilised approach concept is of great importance for the safe operation of an airline during the approach and landing phases (Acarbay & Kiyak, 2020). The elements highlighted in the approach phases are the runway's dry or contaminated condition and length. In the crew, we analyse their competence, recurrence, and fatigue. Another variable is the type of approach, whether it is precision, non-precision or visual. The external conditions of the aerodrome include obstacles, wind, and wildlife—the type of aircraft, whether light, medium or heavy. Due to the large amount of qualitative information derived from the pilots' experience about risk management in the approach and landing phases, this paper proposes an Analytic Hierarchy Process model (AHP) for threat characterisation and risk analysis to achieve a stabilised approach. The results show that AHP proposed model establishes a new methodology for identifying potential in-flight risks to air operations based on expert criteria, improving the decisions to land at an alternate airport based on qualitative information from expert pilots in the risk management field.info:eu-repo/semantics/publishedVersio
Validação de métodos de análise de águas por ICP-AES
Mestrado em Química Analítica e Controlo de QualidadeDada a importância da qualidade da água para a saúde pública, é
muito importante que os laboratórios possuam métodos certificados para a
respectiva análise e controlo da qualidade da água. Por este facto, o presente
trabalho visa avaliar as condições de aplicabilidade do ICP-AES (Plasma
Acoplado Indutivamente à Espectrofotometria de Emissão Atómica) à análise
de metais em águas utilizados para o consumo Humano. Sendo assim, este
trabalho consiste na validação de métodos para a análise de metais em águas
para o consumo Humano. No processo de validação foram estudados diversos
parâmetros, tais como, quantificação do método de ensaio, precisão, exactidão
e cartas de controlo. Os elementos validados no presente trabalho são: Ferro,
Manganês, Zinco, Crómio, Cálcio, Magnésio, Sódio, Potássio e Níquel.
Através do presente trabalho de validação, podemos inferir que os
elementos que apresentam maior sensibilidade, melhores limites de detecção
e quantificação e melhor precisão são o Zinco e o Manganês, apresentando
valores da mesma ordem de grandeza. Por outro lado, o elemento mais
complicado de validar, ou seja, o elemento que apresenta menor sensibilidade
e consequentemente maiores limites de detecção e quantificação é o Potássio.
A utilização de cartas de controlo elaboradas no presente trabalho, permitiu
observar que o método de análise de águas por ICP-AES está sob controlo
estatístico.
ABSTRACT: Given the importance of the quality of the water for the public health,
it is very important that the laboratories possess certified methods
for the respective analysis and control of the quality of the water. For
this fact, the present work aims to evaluate the conditions of
applicability of the ICP-AES (Inductively Connected Plasma to the
Atomic Emission Spectrofotometric) to the metal analysis in waters
used for the human consumption. Being thus, this work consists of
the validation of methods for the metal analysis in waters for the
Human consumption. In the validation process several parameters
had been studied, such as, quantification of the assay method,
precision, accuracy and letters of control. The elements validated in
the present work are: Iron, Manganese, Zinc, Chromium, Calcium,
Magnesium, Sodium, Potassium and Nickel.
Through the present work of validation, we can infer that the
elements with greater sensitivity, better limits of detection,
quantification and better precision are the Zinc and the Manganese,
presenting values of the same order of scale. On the other hand, the
element more complicated to validate, or either, the element that
presents minor sensitivity and bigger limits of detention and
quantification is the Potassium. The use of elaborated letters of
control in the present work, allowed to observe that the method of
water analysis for ICP-AES is under statistical control
Fuzzy electre model for the characterisation of aeronautical operational risks in the approach and landing phase
One of the significant challenges facing the aviation sector is the management of risks arising from its flight operations, especially in the approach and landing phases, where pilot experience and training are of great importance and where the most significant incidents for air safety occur. Therefore, this paper proposes a model inspired by the structure of a Fuzzy ELECTRE model for managing the operational risks that arise in the approach and landing phases that can lead to safety events. Thanks to the analysis of the literature collected, the management criteria and risk parameters to be taken into account for these two flight phases were shown following air safety manuals such as the International Civil Aviation Organization (ICAO) manual, and where the data obtained was obtained qualitatively thanks to the implementation of surveys with expert pilots, whose information served as the primary input for the characterisation of risks. Following the structure of the proposed model, five (5) reference risk scenarios management were constructed using the previous information, and an analysis of the dominance and discrepancy of a risk scenario vs. the previously established reference scenarios was carried out. Finally, it can be concluded that the proposed model allowed the quantitative-qualitative characterisation for managing the most relevant risks in the approach and landing phases, integrating the expertise of experts in this area.info:eu-repo/semantics/publishedVersio
