Decision-Making Tools to Manage the Microbiology of Drinking Water Distribution Systems
2020
[EN] This paper uses a two-fold multi-criteria decision-making (MCDM) approach applied for the first time to the field of microbial management of drinking water distribution systems (DWDS). Specifically, the decision-making trial and evaluation laboratory (DEMATEL) was applied removing the need for reliance on expert judgement, and analysed interdependencies among water quality parameters and microbiological characteristics of DWDS composed of different pipe materials. In addition, the fuzzy technique for order preference by similarity to ideal solution (FTOPSIS) ranked the most common bacteria identified during trials in a DWDS according to their relative abundance while managing vagueness…
Neural generators of the frequency-following response elicited to stimuli of low and high frequency: A magnetoencephalographic (MEG) study.
2021
The frequency-following response (FFR) to periodic complex sounds has gained recent interest in auditory cognitive neuroscience as it captures with great fidelity the tracking accuracy of the periodic sound features in the ascending auditory system. Seminal studies suggested the FFR as a correlate of subcortical sound encoding, yet recent studies aiming to locate its sources challenged this assumption, demonstrating that FFR receives some contribution from the auditory cortex. Based on frequency-specific phase-locking capabilities along the auditory hierarchy, we hypothesized that FFRs to higher frequencies would receive less cortical contribution than those to lower frequencies, hence supp…
A Multi-Criteria Group Decision To Support The Maintenance Service: A Case Study
2015
The present paper wants to propose a methodology to support a group of decision makers into the choice of actions, to implement on a multi-component system, regarding the maintenance service. The choice has to be made on the basis of several criteria, namely the total maintenance cost, the system unavailability and by considering the maintenance actions feasibility. In particular, with the aim to select the maintenance service that represents for the group the best comprise among the criteria to satisfy, the proposed methodology consists of two multi-criteria decisions methods to apply in two successive phases. The first one regards the application of the Analytic Hierarchy Process (AHP) to…
Anomalous Origin and Course of the Right Coronary Artery
2006
Coronary anomalous origin from the wrong aortic sinus has been thought to be a risk factor for ischemia because of acute takeoff from the aorta and flow between the aorta and the pulmonary artery.1–4 A 30-year-old man suddenly died within an hour of waking. His clinical history revealed no evidence of any disease, and the postmortem toxicological examination was negative. Autopsy ruled out violent or natural noncardiac causes …
Concept and Treatment of Hydrocephalus in the Greco-Roman and Early Arabic Medicine
2007
In the ancient medical literature hydrocephalus was not often described although its existence and symptomatology were well known. Most detailed descriptions of hydrocephalus including the surgical treatment are extant in the encyclopaedic works on medicine of the physicians Oreibasios and Aetios from Amida from the 4th and 6th centuries AD, respectively. Because of their broad scientific interests, this type of physicians, typical for the late Roman empire, were known as philosophy-physicians (iota alpha tau rho o sigma o phi iota sigma tau alpha iota). They defined hydrocephalus in contrast to our present understanding as a fluid collection excluding abscesses visible as a bulging tumour …
Role of virtopsy in the post-mortem diagnosis of drowning.
2014
Purpose: Due to admitted limits of autopsy-based studies in the diagnosis of drowning, virtopsy is considered the new imaging horizon in these post-mortem studies. The aim of our study was to evaluate the role of virtopsy performed through computed tomography (CT) in the forensic diagnosis of drowning. Materials and methods: We retrospectively examined the CT data of four cadavers recovered from sea water and suspected to have died by drowning. Each patient underwent a full-body post-mortem CT scan, and then a traditional autopsy. Conclusion: To date, there are no autopsy findings pathognomonic of drowning. This study proves that virtopsy is a useful tool in the diagnosis of drowning in tha…
An Insight into the Role of Postmortem Immunohistochemistry in the Comprehension of the Inflammatory Pathophysiology of COVID-19 Disease and Vaccine-…
2021
On 11 March 2020, the World Health Organization (WHO) declared a pandemic due to the spread of COVID-19 from Wuhan, China, causing high mortality rates all over the world. The related disease, which mainly affects the lungs, is responsible for the onset of Diffuse Alveolar Damage (DAD) and a hypercoagulability state, frequently leading to Severe Acute Respiratory Syndrome (SARS) and multiorgan failure, particularly in old and severe-critically ill patients. In order to find effective therapeutic strategies, many efforts have been made aiming to shed light on the pathophysiology of COVID-19 disease. Moreover, following the late advent of vaccination campaigns, the need for the comprehension …
Postmortem Imaging in Drowning
2019
The diagnosis of drowning is one of the most difficult in the field of forensic medicine since the autopsy findings are often not specific and the laboratory examinations are controversially appreciated by the scientific community. In a cadaver recovered from water, it is of utmost importance to differentiate antemortem and postmortem drowning. This chapter fully investigates biological/thanato-chemical, pathological and imaging findings which may guide the definitive diagnosis.
The History of Rheumatic Diseases
1975
The lectures of Schonlein* (1873) (Fig. 1) state: The nature of this disease being more dynamic, explains the fact that few abnormalities of significance have been found at autopsy. This statement stems from the inadequacy of the then current methods but also suggests a concept of rheumatic diseases, some ingredients of which have survived to this day. However, even a short review of medical history shows progressive differentiation of various disease entities: originally Hippocrates (460–377 BC) took “Rheuma” and “Catarrh” to be synonymous with a process during which “mucous flux” left the brain for various foci in the entrails and also the joints, and there produced disease. He mentions “…
Three-dimensional helical computed tomography in prenatal diagnosis of fetal skeletal dysplasia
2013
Objectives (1) To study the use and diagnostic value, as a complement to ultrasound, of helical computed tomography (helical CT) to differentiate normal fetuses from cases of skeletal dysplasia; (2) to define the most relevant indications for helical CT; and (3) to evaluate its diagnostic performance with respect to radiological criteria considered discriminatory. Methods This was a retrospective study from 2005 to 2008 in 67 pregnant women who underwent helical CT after 26 weeks of gestation for suspected fetal skeletal dysplasia due to fetal shortened long bones on ultrasound (≤ 10thpercentile), either alone or associated with other bone abnormalities. The results were compared with pedia…
