Autopercepción de las competencias ciudadanas en estudiantes de educación física en Santiago de Chile

Las competencias ciudadanas se pueden describir como aquellas herramientas que orientan y forman a los ciudadanos de manera integral. En el contexto de la Educación Física, existen escasos estudios abordando esta temática, y tampoco se encontraron instrumentos validados en dicha población. Los objeti...

Qualitative Histologic Assessment vs. Geomorphometric Analysis of Nerve Fiber Shape after the Intraneural Application of Liposomal Bupivacaine

Int. j. morphol; 41 (3), 2023
SUMMARY: The preserved form of all components of the nerve fiber is a prerequisite for the proper conduction of the nerve impulse. various factors can change the shape of nerve fibers. In everyday practice, qualitative histological analysis is the gold standard for detecting changes in shape. Geometric m...

Sex estimation based on foramen magnum: a three-dimensional geometric morphometrics approach

Int. j. morphol; 41 (2), 2023
SUMMARY: The foramen magnum is an important topographic opening which connects cranial cavity and spinal canal. The analysis of the bone material established that there are differences in the shape of the foramen magnum between individuals. The aim of this study was to determine sex based on shape and si...

Variation in phenolic, antioxidant and vitamin amounts among some medicinal plants and investigation by PCA analysis: Lamiaceae family

Aromatic and medicinal plants are of great importance to determine the contents of the active compounds of plant origin and to evaluate them depending on variety and climate factors in order to determine the phenolic, antioxidant enzyme activity, vitamin contents in species belo...

F approach algorithm in missing landmark problem

Int. j. morphol; 40 (1), 2022
SUMMARY: Missing data may occur in every scientific studies. Statistical shape analysis involves methods that use geometric information obtained from objects. The most important input to the use of geometric information in statistical shape analysis is landmarks. Missing data in shape analysis occurs whe...

Planejamento e desenvolvimento de novos compostos com atividade frente a Leishmania spp: Síntese, avaliação da atividade e toxicidade de derivados 5-nitro-2-furfurilidênicos e estudos de relações estrutura-atividade

A leishmaniose é uma zoonose de ampla distribuição mundial, causada pelos parasitas tripanossomatídeos do gênero Leishmania. Infelizmente, o arsenal terapêutico disponível é precário, mas vê-se crescente o interesse científico pela busca do potencial de derivados nitroheterocíclicos como alte...

Revisão taxonômica de Psalidodon eigenmanniorum (Cope) com base em análises morfométrica, merística e padrão de colorido (Characiformes: Characidae)

Iheringia, Sér. zool; 112 (), 2022
A identidade de Psalidodon eigenmanniorum (Cope, 1894) e a possibilidade de se constituir em mais de uma espécie é testada através de análises da morfometria (19 medidas), dos caracteres merísticos (14 contagens) e do padrão de colorido de 705 exemplares provenientes dos sistemas dos rios TramandaÃ...

Application of back propagation neural network in sports fatigue indicators

Rev. bras. med. esporte; 27 (3), 2021
ABSTRACT Introduction High-intensity rehabilitation training will produce exercise fatigue. Objective A backpropagation (BP) network neural algorithm is proposed to predict sports fatigue based on electromyography (EMG) signal images. Methods The principal component analysis algorithm is used to re...

The improvement of pca algorithm and its application in the prediction of elbow knee joint injury

Rev. bras. med. esporte; 27 (5), 2021
ABSTRACT Objective: There were many constraints produced by training time and joint injury to analyze the influence of the training intensity on the elbow and knee joints of athletes during the training process. Methods: An improved algorithm-based master component analysis (PCA) modeling method is pro...
