Relation between implant/abutment vertical misfit and torque loss of abutment screws

This study investigated whether there is a direct correlation between the level of vertical misfit at the abutment/implant interface and torque losses (detorque) in abutment screws. A work model was obtained from a metal matrix with five 3.75 x 9 mm external hex implants with standard platform (4.1 mm). Four frameworks were waxed using UCLA type abutments and one-piece cast in commercially pure titanium. The misfit was analyzed with a comparator microscope after 20 Ncm torque. The highest value of misfit observed per abutment was used. The torque required to loose the screw was evaluated using a digital torque meter. The torque loss values, measured by the torque meter, were assumed as percentage of initial torque (100%) given to abutment screws. Pearson's correlation (α=0.05) between the misfit values (29.08 ± 8.78 µm) and the percentage of detorque (50.71 ± 11.37%) showed no statistically significant correlation (p=0.295). Within the limitations of this study, it may be concluded that great vertical misfits dot not necessarily implies in higher detorque values

Calculia: an innovative game to assist individuals with learning difficulties in basic mathematics operations

The educational application entitled “CALCULIA: An innovative game to help people with learning difficulties in basic Mathematics operations” was developed by a multidisciplinary team from the Federal Institute of Education, Science and Technology of Maranhão and Piauí – IFMA and IFPI, together with the Department of Education of the Government of the State of Maranhão – SEDUC-MA, formed by teachers, students and volunteers, to be used in formal and non-formal learning spaces, aiming to teach basic mathematical operations, as well as numerical symbolic understanding, targeting people with dyscalculia. Gamification was inserted as a teaching-learning strategy to acquire mathematical knowledge such as: addition, subtraction, multiplication and division, in addition to understanding mathematical symbols: figures, proportions, concepts and formulas. The methodological path adopted was Applied Behavior Analysis – ABA, for which bibliographical surveys, document analysis, prior search and field research were carried out, followed by the computational steps for the prototyping process, character creation, application development process, creation levels, prototype testing, adjustments and application validation. Its approach focused on verbal and operational dyscalculia with the aim of helping professionals in the field of Education and Health, improving the quality of life of individuals with dyscalculia. The evidence found reinforces the need to expand the project to cover practical, lexical, graphic and ideognostic dyscalculia

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions. Please cite this data paper when using the data in publications. We also request that researchers and teachers inform us on how they are using the data
