An Experimental method to determine micromechanical properties of thin films using the atomic force microscope

A promising method has been developed to determine micromechanical properties of thin film materials. Metal and ceramic thin films are used extensively in the computer microprocessor industry and in the relatively new field of Micro- Electromechanical Systems (MEMS). The push for miniaturization and increased performance out of the computer microprocessor and MEMS devices have pushed materials to their limits. Micromechanical properties are very difficult to obtain due to the lack of adequate testing equipment on the microscale. The atomic force microscope (AFM), most commonly used as an imaging tool, lends itself to mechanical interaction with the sample surface by means of a microscale cantilever probe. Using an array of microbeams fabricated from an aluminum thin film in the microfabrication facilities at RIT, the AFM was utilized to deflect the microbeams. Force and deflection information gathered yielded micromechanical properties such as stiffness and elasticity for the aluminum thin film

Aplicabilidad de la goniometría mediante videografía en el seguimiento de programas de flexibilidad

El objetivo del siguiente trabajo es el de evaluar los efectos de un programa específico de la mejora de la flexibilidad isquiotibial, utilizando la videografía como metodología para el cálculo del ángulo de extensión de rodilla. La muestra ha estado formada por 75 deportistas escolares con un rango de edad de entre 7 y 16 años. Los resultados nos muestran como antes de la intervención sólo un 5% de los casos era considerado flexible (ángulo<20º). Después de la intervención, el porcentaje de flexibles fue del 21% (p=0,002). No obstante, el 47% de los casos había mejorado su flexibilidad. Esta mejora estaba asociada al género (OR niños vs. niñas 3,7 (IC95% 1,04–13,16)), y a la edad (OR 0,78 por año (IC95% 0,62–0,97)), no observándose asociación con las características antropométricas. La intervención practicada fue efectiva, tanto en relación al aumento de casos considerados flexibles, como al número de casos que habían mejorado su flexibilidad. La posibilidad de mejora de la flexibilidad es mayor en los niños y disminuye con la edad. La videografía es un método objetivo para el cálculo del rango de movimiento, hace posible la comparación visual entre dos tests realizados y permite dar un feedback al deportista.The purpose of this study was to investigate the influence of a hamstring stretching program, using videography as the methodology to calculate knee extension range of motion. 75 scholar football players, between 7 and 16 years old, were evaluated. 5% (angle <20º) of the subjects had hamstrings flexibility limitation before the stretching program and 21% (p=0,002) of the total population had flexibility limitations after the program conclude. Nevertheless, 47% of subjects showed increases in their flexibility between first and second assessment. The improvement of flexibility is gender (OR boys vs. girls 3,7 (IC95% 1,04–13,16)) and age (OR 0,78 per year (IC95% 0,62–0,97)) correlated. No association was found with anthropometric characteristics. The stretching program was successful for the improvement of hamstrings flexibility. Boys have greater possibility to improve flexibility and it decreases in relation with age. Videography is an objective methodology to analyze range of movement, allows the visual comparison between tests and gives a feedback to the subject

Comparación entre la videografía y el método Sit and Reach para la valoración de la flexibilidad isquiotibial en deportistas escolares

Existen diferentes test para evaluar la flexibilidad articular. El objetivo de nuestro estudio era el de comparar el test de sit and reach y el de goniometría de la rodilla en extensión, mediante videografía para la valoración de la flexibilidad isquiotibial en una muestra de 139 deportistas escolares, de edades comprendidas entre los 7 y los 16 años. El coeficiente de Kappa muestra una concordancia muy débil entre las dos pruebas (0,022 (I.C. 95% -0,07 – 0,12)). Demostrando que el sit and reach no es un test válido para la evaluación de la flexibilidad isquiotibial.There are different test to evaluate flexibility of human movement. The comparison of sit and reach test and videogaphy measurement of hamstrings flexibility was the purpose of this study. 139 scholar football players, between 7 and 16 years old, were evaluated. Kappa coefficient shows little concordance between the two tests (0,022 (I.C. 95% -0,07 – 0,12)) which demonstrates that sit and reach test is not valid enough for hamstrings flexibility evaluation

Du théologique au religieux: l'usage de la rhétorique dans les pensées de Marc Aurèle

Our purpose is to renew the studies on the relationship between Rhetoric and Philosophy in Marcus Aurelius’s Meditations: beyond its unquestionable therapeutic function, does Rhetoric have a religious dimension? Is it legitimated by the author as a powerful expression of the stoic piety? In his meditations on cosmic order, Marcus Aurelius uses the stylistic features of the hymn: these fragments become a praise of the divine world but they haven’t the same religious value than philosophical hymns since they are first addressed to the self, not to the God. They reveal the ambiguity of stoic asceticism which considers moral introspection and devotion to God as the one and same movement. Rhetoric expresses the fervent desire to conform to the cosmic design but it is also the sign of the proficiens’ imperfection

A Cross-Cultural Comparison of the Cognitive and Mental Health Repercussions of Childhood Adversity in Adulthood

The majority of individuals in the United States experience at least one type of traumatic during childhood (“Understanding Child Trauma”, 2017). Individuals with childhood adversity have an increased incidence of depression, anxiety, and alcohol abuse during adulthood (Rehan et al., 2017). However, the consequences of early adversity are not limited to mental health and extend to areas of cognitive functioning (e.g., working memory). The present research study addresses the long-term consequences of childhood adversity on psychological and cognitive functioning. Data collection took place online from February 2019 - April 2019 in Iceland and the United States. The survey assessed outcomes including anxiety, depression, resilience, PTSD, trauma, and working memory. The results indicate that Iceland and the United States did not show differences in PTSD symptomology or adversity. There was a significant difference in the scores for depression between the two countries, conditions; t(192.96)= 1.71, p=.04. Additionally, resilience differed between the United States and Iceland, t(146.537)= 1.21, p=.02. The individuals with moderate trauma from both countries reported higher anxiety and depression compared to the participants without trauma. In addition, Individuals showing higher levels of PTSD symptomology had greater depression, anxiety, and lower resilience compared to individuals without PTSD symptomology. The research study compared the types of reported traumas between the United States and Iceland and the differences in mental health functioning between the two countries. This study provides evidence that individuals from both countries who report more PTSD symptomology and higher trauma show differences in the following areas of anxiety, depression, and resilience
