Exploring the psychophysiology of mantra meditation: effects of repetitive speech on attention, autonomic control, and cortical entrainment

A fala repetida foi considerada como uma componente fundamental da meditação com mantras, mas muito permanece por saber acerca dos mecanismos neurocognitivos que poderá envolver. Este estudo teve dois objetivos principais: perceber se a fala repetida com um mantra e a fala repetida com palavras elicitaria os correlatos típicos da meditação com mantras (atenção e controlo autómico aumentados) de forma semelhante; testar se a fala repetida elicitaria entrainment cortical à frequência de repetição. Os participantes (n = 12) realizaram tarefas de fala repetida em três condições: mantra repetido a um ritmo de 0.2 Hz, palavra repetida a 0.2 Hz e palavra repetida a 1 Hz. Foram obtidas medidas comportamentais e eletrofisiológicas durante uma tarefa auditiva oddball como marcadores de atenção, e foi medido o ritmo cardíaco. Os resultados indicam que tanto a fala repetida com um mantra como a fala repetida com palavras levaram a uma redução generalizada da responsividade a estímulos não-alvo. A repetição contínua e rítmica de palavras não-mantra é, por isso, capaz de modular a atenção, um resultado que acrescenta à evidência de que a fala repetida é uma componente relevante da meditação com mantras. Por outro lado, o controlo autonómico não foi afetado significativamente pela fala repetida. Não foi também encontrada evidência de entrainment à frequência de repetição

Theatrical Confrontation: Social Confrontation

This paper intends by establishing connexion between the tragic form and the destiny of the African descendant in Brazil to show that this is not the so-called country of racial democracy For this the relations between society and the Brazilian theater will be observed presenting aspects of the foundation and the importance of the genre The discussion will be illustrated with the capital speech of the central character of Antonio Callado s play A Revolta da Cacha a 1982 He is Ambr sio black actor to whom they only support supporting roles Ill he goes to meet Vito friend and playwright to seek the play promised for years and which would be the protagonist The play is still unfinished and Ambr sio decides that he will not leave until the work is completed With the negative of Vito the confrontation is establishe

The optimization of the logistics chain at Jerónimo Martins: The centralization decision

This work project results from a challenge proposed by Jerónimo Martins, the largest food distribution group in Portugal, which consists in developing a simulator to support the centralization decision in Recheio, a cash & carry chain. A quantitative analysis was performed to understand the dispersion of purchasing volume by region and centralization degree. The simulator designed intends to acknowledge the impact of a specific decision on three dimensions: economic, environmental and social. The economic costs, CO2 emissions and stock-out probabilities, are presented for both centralized and decentralized scenarios. In the end, this project aims to optimize the company’s logistics chain

Preparation and characterization of stainless steel 316L/HA biocomposite

The austenitic stainless steel 316L is the most used metallic biomaterials in orthopedics applications, especially in the manufacture of articulated prostheses and as structural elements in fracture fixation, since it has high mechanical strength. However, because it is biologically inactive, it does not form chemical bond with bone tissue, it is fixed only by morphology. The development of biocomposites of stainless steel with a bioactive material, such as hydroxyapatite - HA, is presented as an alternative to improve the response in the tissue-implant interface. However significant reductions in mechanical properties of the biocomposite can occur. Different compositions of the biocomposite stainless steel 316L/HA (5, 20 and 50 wt. (%) HA) were prepared by mechanical alloying. After milling the powders for 10 hours, the different compositions of the biocomposite were compacted isostatically and sintered at 1200 ºC for 2 hours. The mechanical properties of the biocomposites were analyzed by compression tests. The powders and the sintered composites were analyzed by scanning electron microscopy (SEM) and X-ray diffraction (XRD).Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Universidade Federal de Itajubá IEMUniversidade Federal de Itajubá Instituto de Ciências ExatasUniversidade Federal de São Paulo (UNIFESP) Instituto de Ciência e TecnologiaUNIFESP, Instituto de Ciência e TecnologiaSciEL

Prediction models applied to lung cancer using data mining

Lung cancer is the most common cause of cancer death in men and the second leading cause of cancer death in women worldwide. Even though early detection of cancer can aid in the complete cure of the disease, the demand for techniques to detect the occurrence of cancer nodules at an early stage is increasing. Its cure rate and prediction are primarily dependent on early disease detection and diagnosis. Knowledge discovery and data mining have numerous applications in the business and scientific domains that provide useful information in healthcare systems. Therefore, the present work aimed to compare several prediction models as well as the features to be used, with the help of Weka and RapidMiner tools. Both classification and association rules techniques were implemented. The results obtained were quite satisfactory, with emphasis on the Naive Bayes model, which obtained an accuracy of 95.03% for cross-validation 10 folds and 94.59% for percentage split 66%.This work has been supported by FCT—Fundação para a Ciência e Tecnologia within the R&D Units Project Scope: UIDB/00319/2020

Adaptação transcultural do instrumento Family Needs Questionnaire

This is a quantitative methodological development study on the cross-cultural adaptation of the "Family Needs Questionnaire" (FNQ), which is a structured instrument developed in the United States to measure the perceived needs of family members after the Traumatic Brain Injury (TBI) of a relative. This instrument aims to identify important needs presented by family members, whether met or not. The FNQ translation and adaptation followed a particular method, which permitted to achieve semantic, idiomatic, cultural and conceptual equivalence of the instrument version labeled in Portuguese as "Questionário de Necessidades da Família". The results of the questionnaire application to 161 family members showed that the instrument content is valid to measure the needs of families of patients with TBI in the Brazilian context.Se trata de estudio cuantitativo de desarrollo metodológico sobre la adaptación transcultural del Family Neds Questionnaire (FNQ), instrumento estructurado, desarrollado en los Estados Unidos, para medir las necesidades percibidas por los miembros de la familia, después del trauma cráneo encefálico (TCE) de un familiar. El propósito de ese instrumento es identificar necesidades atendidas y no atendidas importantes para los familiares. La traducción y adaptación del FNQ siguieron una metodología propia que permitió alcanzar equivalencia semántica, idiomática, cultural y conceptual del instrumento traducido, denominado, en portugués, Cuestionario de Necesidades de la Familia.

Influence of temperature and photoperiod on the maturation of the seminal vesicle and albumen gland in Oxychilus (Drouetia) atlanticus (Gastropoda: Pulmonata)

The land snail Oxychilus (Drouetia) atlanticus is endemic to São Miguel (Azores). In this species, the reproductive system, especiailly the glandular organs, changes in size and shape during the reproductive cycle. As maturation-diagnostic organs, the seminal vesicle and the albumen gland have complementary interpretations. While the former is appropriate to establish the phase of the pre-copulatory and copulatory periods the latter appears a more accurate way to define pre-egg-laying and egg-laying periods. Concerning the effects of photoperiod and temperature on both organs, it seems that while the former triggers the physiological phenomena related to reproduction, inducing the seminal vesicle and the albumen gland to mature, the latter acts mainly as a regulatory factor for these organs, delimiting the distinct phases of reproduction
