Preliminary studies on the volumetric capacity of ceramic from the Neolithic site of Lugo di Grezzana (VR) through 3D graphics software
Get PDFThe aim of this study is to obtain an estimate of the volumetric capacity of a selection of ceramic vessels from the Neolithic site of Lugo di Grezzana (Verona, Italy). The method applied involved the use of Blender, a free and open source 3D computer graphics software. This program can calculate the volume from the graphic elaboration of the archaeological drawing of the artifacts. Through the calculation of volume it has been possible to obtain an estimate of the total capacity of the vessels, proposing two types of content. Volumetric estimates were then compared between the diameter and height of each ceramic vessels, to define size classes. The research shows that the internal variability of some ceramic shapes could be the consequence of different functional and/or cultural choices. The methodology tested in this paper could be applied in future research projects
Morphometric analysis for geoarchaeological research: from testing different methods to results verification in the Romagna plain
Get PDFThe Multi-Scale Relief Model (MSRM) is a novel algorithm developed for the visual interpretation of landforms. This was tested within the Romagna plain, the south-eastern part of the Po Valley (Italy), to establish whether it was able to detect fluvial ridges within this alluvial landscape. Since the MSRM is not the only method to carry out morphometric analysis, it was compared with other techniques previously used in landscape archaeology, such as the Topographic Wetness Index (TWI), the Topographic Position Index (TPI), and the Deviation from mean Elevation (DEV). At the same time, the SRTM 1 Arc-Second Global was compared with a Local DEM based on ground control points. Subsequently, the result of the MSRM algorithm was tested through targeted desktop- and field-based research. This validation phase proved essential to test the accuracy of the DEM-derived products. Furthermore, it allowed us to verify the existence of the detected fluvial ridges, to propose a chronological range for some of them, and, finally, to collect new archaeological evidence
PARMAUMENTATA. Ricerca archeologica, augmented reality e user experience nella ricostruzione del paesaggio urbano di Parma
Get PDFThe core of the research project CittAumentata is the development of a software tool that fully uses the potential of AR as a way of understanding and improving ancient landscapes. The app links a model of collecting and processing archaeological and topographical datasets to an experience that increases users’ interaction thanks to the ease-to-use and compatibility with most of the devices (smartphones and tablets). The scalability and the certification of a data protocol allows to systematize an innovative tool that manages 3D data and offers to citizenship a new way to understand cultural heritage and historical stratification in landscapes
The rediscovery of colors at Kainua-Marzabotto, in Baldoni V. (ed.), From Pottery to Context. Archaeology and Virtual Modelling
Get PDFThe city of Kainua (Marzabotto), inhabited between the end of the 6 th century BC and the beginning of the 4th century BC, is one of the most important and best-preserved Etruscan centers. During the excavations performed by the University of Bologna in the area of the temple of Uni, masses of rare red ochre and Egyptian blue pigments have been found. After this discovery, a series of analyses has been carried out in order to study the polychromy of the architectural terracottas of the site. Thanks to spectroscopic analysis, it has been possible to examine the composition of the pigments that were employed. Moreover, the Visible- Induced Luminescence (VIL) technique not only confirmed the use of Egyptian blue, but also allowed to rediscover the decoration pattern of some painted tiles which belonged to one of the temples of the acropolis. This discovery is very important because the use of Egyptian blue had never been attested before in the Etruscan Po Valley. Lastly, the study has allowed to create a 3D reconstruction of some painted architectural elements, which are preserved nowadays in fragments

Get PDFIn this research thesis (part III), we analyze a formula concerning the Zeros of the Davenport Heilbronn Function. We describe further new possible mathematical connections with some equations concerning some sectors of String Theory and Supersymmetry Breaking

Rare Presentation of a Metastatic Pancreatic Neuroendocrine Neoplasm Presenting with Atrial Flutter
Get PDFPancreatic neuroendocrine neoplasms (PanNENs) rarely secrete serotonin, which is the main cause of carcinoid syndrome. One of its unusual manifestations is carcinoid heart disease or Hedinger’s syndrome which is seldom accompanied by cardiac arrhythmias. We report the case of an 88-year-old woman who presented with recently experienced episodes of palpitations and a newly developed atrial flutter with a ventricular rate of 130 beats per minute. Echocardiography revealed thickened and tethered tricuspid and pulmonary valve leaflets causing severe valvular regurgitation and right ventricular dilatation. Episodes of intermittent diarrhoea over the previous 2 years were mentioned, making carcinoid syndrome our working diagnosis. The 5-hydroxyindoleacetic acid (5-HIAA) levels in a 24-hour urine collection specimen were elevated. Conventional imaging studies and a Ga-68 dodecane tetraacetic acid tyrosine-3-octreotate (DOTATATE) positron emission tomography/computer tomography (PET/CT) scan revealed the presence of a metastatic PanNEN arising from the pancreatic tail. The patient was managed with lanreotide and telotristat with remarkable improvement of her symptoms. To our knowledge, this is the first reported case of carcinoid syndrome presenting with atrial flutter as the initial symptom
COVID-19-Induced Pancytopenia in a Major Molecular Response CML Patient on Dasatinib: A Case Report and Review of the Literature
Get PDFSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), has caused a global health crisis. COVID-19 can have a multifaceted presentation, and a wide range of complications and outcomes may emerge based on the severity and comorbidities of the infected patient. We report the case of a 42-year-old man with a history of chronic myeloid leukaemia (CML) on dasatinib (in major molecular response) who was diagnosed with COVID-19 and developed pancytopenia. Our case report and review of available publications add to the limited literature available regarding COVID-19 in CML
Use of Brentuximab Vedotin in a Non-HIV Patient with Primary Effusion Lymphoma
Get PDFPrimary effusion lymphoma is a rare and aggressive large B-cell lymphoma presenting as malignant effusion with poor prognosis. Although it is more prevalent among HIV patients, it has also been described in non-HIV immunocompromised individuals. Given its rarity, there are no large randomized trials regarding the best therapeutic option. The choice of therapy is based on retrospective studies, case reports and preclinical data. We present the case of a non-HIV patient with relapsed disease after treatment with CHOP who was then successfully treated with brentuximab vedotin, achieving complete remission
Metamizole-Induced Type I Kounis Syndrome
Get PDFKounis syndrome (KS) is defined as acute coronary syndrome (ACS) triggered by mast cell and platelet activation in the setting of allergic or anaphylactic insults. KS is a unique and complex cause of ACS and many cases may be missed due to its highly variable clinical manifestations. In this report, we present a case of KS type I triggered by metamizole in the absence of a previous history of allergy to this drug. Following the administration of metamizole, the patient developed generalized acute urticaria, chest pain and diaphoresis. Electrocardiography (ECG) showed ST-segment elevation suggestive of myocardial infarction complicated by ventricular tachycardia. No coronary disease was observed on coronary angiography. The cardiac manifestations of KS may be life-threatening, and so it is important to appropriately recognize and treat this condition
