Autistic Spectrum Disorder and Dental Management
To analyze the scientific production on the dental management of individuals with Autism Spectrum Disorder (ASD), in light of the current literature, considering its implications for professional practices, health communication, and inclusive care. An integrative review with a descriptive and qualitative approach was conducted in major electronic databases in order to answer the following guiding questions: what are the difficulties and potential…
Radiocarbon analysis of mixed-sources plastic
In Brazil, laws are being adopted prohibiting the use and distribution of non-recyclable plastic bags and encouraging the use of recyclable, biodegradable and bioplastic bags. However, there is no specific standard method in Brazil to inspect the carbon content of bioplastics. This work aims to implement the sample preparation for radiocarbon biogenic fraction determination in bioplastics in the new radiocarbon laboratory at the Federal Universit…
Cardiac tamponade as the initial presentation of t-cell lymphoblastic lymphoma in a young female
T-cell lymphoblastic lymphoma (T-LBL) is a rare and aggressive subtype of non-Hodgkin lymphoma. It often presents with mediastinal masses, but its initial manifestation with cardiac tamponade is exceedingly uncommon. We report the case of a 24-year-old female presenting with progressive dyspnea due to large pericardial effusion with tamponade physiology, leading to the diagnosis of T-LBL. The patient underwent partial pericardiectomy followed by …
Methodological tests using Amazonian soil samples for 14 C-AMS dating
Although radiocarbon-accelerator mass spectrometry ( 14 C-AMS) is an important tool for the establishment of soil chronology, its application is challenging due to the complex nature of soil samples. In the present study, chemical extraction methodologies were tested to obtain the most representative age of Amazonian soil deposition by 14 C-AMS. We performed acid hydrolysis with different numbers of extractions, as well as treatments combining ac…
Seized ivory in Brazil
Within a collaboration between the Brazilian Federal Police and the Radiocarbon Laboratory of the Fluminense Federal University (LAC-UFF), this work studies seized art objects made from ivory. We aim to develop protocols to verify whether they are illegal according to the Convention on International Trade of Endangered Species from Wild Flora and Fauna (CITES) law by measuring the carbon-14 concentration in the modified ivory samples from differe…
Brazilian AMS Radiocarbon Laboratory (LAC-UFF) and intercomparison of preliminary results with Sample Preparation Laboratory (Lapa 14 C – Ufba)
This study presents the initial results of carbon-14 dating after performing sample preparation and graphite production processes at the Federal University of Bahia (UFBA) in an intercomparison with the same processes performed at the Radiocarbon Laboratory of the Fluminense Federal University (LAC-UFF). Both laboratories are located in Brazil. The accelerator mass spectrometry (AMS) system at LAC-UFF was used for radiocarbon measurements. To ver…
Radiocarbon dating in South America and the impact of the continent's first 14 C‐AMS facility to archaeological research
Due to the lack of formal historical records, the pre‐Columbian history of the American continent is often referred to as prehistory. The large population decline following the arrival of Europeans, mainly due to the extinction of several cultural groups, combined with the lack of written records, means that researchers may often have to rely primarily on archaeological evidence. For this reason, the radiocarbon dating technique has been crucial …

Biogenic carbonate samples
Most of the carbonate samples have a basic well-defined pretreatment protocol for 14 C-AMS dating, but particularities of specific organisms have to be treated with care. This is the case of stromatolite samples, in which carbonate is formed by biogenesis and also has a porous structure that could contain recent organic material as a contaminant. In this work, we analyzed the differences in the radiocarbon content by using organic matter removals…
Assessing the 14 C Marine Reservoir Effect in Archaeological Contexts
Prehistoric shell mounds can be useful for the quantification of the radiocarbon marine reservoir effect (MRE) and, at the same time, knowledge about the MRE allows for the establishment of robust chronologies for these sites. This creates a loop in which the archaeological setting has a dual role: it is part of both the method and the application. Therefore, it is paramount to address these sites from both archaeological and environmental perspe…
Preliminary Radiocarbon Dating Results of Bone Samples at the Lac-Uff, Brazil
Collagen extraction depends on the state of bone preservation, and the acidity of Brazilian soils often prevents the use of this material for radiocarbon dating. When available, however, bone samples constitute very important chronological records for both archaeological sites and natural depositional sites of specific animals. The extraction of collagen was performed using two filters, the first aiming to remove insoluble contaminants, and the s…
Establishing Water Sample Protocols for Radiocarbon Analysis at Lac-Uff, Brazil
Since the establishment of the first radiocarbon accelerator mass spectrometry facility in Latin America in 2009, the Radiocarbon Laboratory team of Universidade Federal Fluminense (LAC-UFF) has worked to improve sample preparation protocols and increase the range of environmental matrices to be analyzed. We now present the preliminary results for DIC sample preparation protocols. The first validation tests include background evaluation with pMC …
Lac-Uff Status Report
The Radiocarbon Laboratory of the Fluminense Federal University was installed in 2009, and its NEC Single Stage Accelerator Mass Spectrometry system has been operational since 2012. As the first 14 C-AMS facility in Latin America, the LAC-UFF became a reference center for radiocarbon ( 14 C) dating in Brazil. Over the years we have implemented pretreatment protocols for several kinds of materials, such as cellulose, soil, bone, and biofuels. In t…
Otolith-Based Chronology of Brazilian Shellmounds
The radiocarbon ( 14 C) chronology of hunter-fisher-gatherers’ archaeological settlements along the Brazilian coast is usually based on mollusk shells, charcoal from hearths, and eventually human bones. However, fish otoliths are found in several archaeological contexts and may represent a reliable option as a chronological record. In this work, we compare the 14 C dates of whitemouth croakers ( Micropogonias furnieri ) otoliths with dates obtain…
Os princípios do "Specula Principum" nas narrativas pedagógicas de Ramon Llull
A presente reflexão tem como objetivo discutir as narrativas pedagógicas para a formação política do príncipe, presentes na obra de Ramon Llull. A obra analisada se caracteriza como fonte de formação moral e política, de modo que fazemos referência desta obra aos "Espelhos de Príncipe" (Specula Principum) enquanto narrativas medievais pautadas em uma pedagogia prescritiva e normativa. O bom príncipe, de acordo com Llull, deve ser a imagem de Deus…
Potential Use of Archaeological Snail Shells for the Calculation of Local Marine Reservoir Effect
Shellmounds are archaeological sites found across the Brazilian coast and form an important record of the human occupation of this area during the Holocene. The presence of both terrestrial and marine remains within the same archaeological context enables the comparison of different carbon reservoirs. There is only a small number of similar studies for the coast of south-southeastern Brazil. Previous work was based on the analysis of pre-bomb she…
