The Use of Animation in Propaganda: Caricature to Depict the Enemy

This is an essay about the use of animation as a vehicle for propaganda, using the World War II Disney cartoon short Der Fuehrer's Face (1943) and the North Korean television show Squirrel and Hedgehog (1970-) as examples. The essay analyzes and compares these two cartoons focusing on their ideological content as well as on how their technical aspects and features as animation works are used to deliver their propagandistic message. It describes the mechanisms of propaganda and how it works, and more concretely how caricaturization and humour are used in propaganda to depict the enemy in a negative light. It also pays attention to the historical context of both texts, taking into account how propaganda is used differently in contemporary North Korea and 1940s USA in terms of methods, intended audience and technical aspects

Effects of 8-Weeks Concurrent Strength and Aerobic Training on Body Composition, Physiological and Cognitive Performance in Older Adult Women

(1) Background: Despite plenty of evidence supporting the advantages of regular physical exercise amongst older women, it is not clear what the best methodology is to improve these parameters. Considering the growth of older population and aging process, this study analyses an 8-weeks concurrent training intervention; (2) Methods: A total of 48 older women participated in concurrent strength and aerobic exercises training intervention being used to know physical and cognitive improvements in older women through physical, physiological and vigilance tests; (3) Results: Significant differences were found in weight and body mass index (BMI) between pre-intervention and post-intervention and even better results, but non-significative, in maximum oxygen consumption (VO2max), total fat percentage and skeletal muscle mass. Additionally, we found cognitive improvements in vigilance (RT) related to executive functions. (4) Conclusions: An 8-weeks concurrent training program (strength and aerobic exercises) give another efficient possibility to obtain better physical, physiological and cognitive improvements in older women

A modification of the Norris failure criterion for the prediction of the mechanical failure of the aged paper insulation in the windings of a power transformer

The deterioration of the insulation in the windings of power transformers affects their lifespan. A commercial insulated Continuously Transposed Conductor (CTC) was studied experimentally, numerically and analytically. The purpose was to understand the mechanisms governing the mechanical failure of the insulating paper, and to achieve a criterion for predicting failure under different conditions. Samples of that insulated CTC were extracted from a coil and aged at 150∘C for different durations inside vessels filled with naphthenic oil. Then the degree of polymerisation and tensile, compressive and shear mechanical properties of the insulation were measured/estimated. Aged insulated CTC samples were subjected to three-point bending tests, producing deformations compatible with a short circuit, and the fractures in the insulation were analysed. The bending test over a CTC sample was simulated by means of a FEM Program. The Norris failure model, applicable to a lamina, was adapted to the studied insulation materials. The predictions of that failure criterion agreed with experimental observations

Experimental dataset on the tensile and compressive mechanical properties of plain Kraft and crepe papers used as insulation in power transformers after ageing in mineral oil

The solid insulation in the windings of power transformers, which generally consists of oil-impregnated thin paper, is one of the key elements for the performance and durability of these electrical machines. Insulation paper is subjected to static and dynamic forces of electromagnetic origin, in combination with high temperatures and chemical reactions, during the operating life of a power transformer. The mechanical properties of the cellulosic insulation are relevant parameters because its breakage could result in the electric failure of the transformer. Indeed, paper manufacturers usually provide values of the tensile strength and elongation at breakage of the insulating paper in its two principal material directions, the MD (machine direction) and CD (cross-direction). However, paper is a highly anisotropic material and its material properties evolve as the paper insulation ages. The paper insulation in an operating transformer is subjected to a multiaxial stress state field including compressive and shear stresses. This article reports experimental data on the tensile and compressive mechanical properties of two types of paper, plain Kraft and crepe paper, typically used as insulation in power transformers, under different ageing states (which were induced through accelerated thermal ageing and quantified by means of the degree of polymerisation). These data could be reused for several purposes. They can improve the current understanding of the mechanical response and degradation processes of the cellulosic insulation in power transformers, and give some reference values that can be compared with others obtained in the factory by manufacturers. In the field of engineering failure analysis, those values could be reused for the assessment of mechanical failure of paper materials used in power transformers, see [1]

Mechanical behaviour of the cellulosic dielectric materials of windings in power transformers in operation

Power transformers are crucial elements in electrical systems, and the end of their useful life is commonly conditioned by the degradation of the cellulosic insulation materials inside them. These materials are subjected to elevated temperatures and mechanical stresses, generated by electrical solicitations which deform the copper conductors and subsequently the paper, and also to the chemical reactions which take place in the dielectric oil in which the paper is impregnated. In order to better understand the behaviour of cellulosic insulation, we have studied the previous bibliography analysing the mechanical behaviour of cellulosic materials. At present, there are no experimental results analysing how the paper responds to the deformation suffered by the copper conductor in a realistic situation. We have developed a simulation model describing the mechanical behaviour of a standardised copper conductor wrapped with four layers of dielectric paper, using ANSYS Workbench Static Structural, which will be compared with experimental results afterwards

Is positive self-perception a determinant of cardiovascular performance? A didactic and sustainable view in female university students

Traditionally women have been less active and physically active than men. Although the recent literature indicates this gender gap, the sexes' difference when practicing sport seems to be decreasing. This study framework's importance could be reflected in the 17 Sustainable Development Goals (SDG) proposed by UNESCO, which highlight the need to generate strategies to improve health (SDG 3) and equalize opportunities between men and women (SDG 4). The reasons for these differences are multifactorial, with intrinsic and extrinsic motivations indicated as requiring further research. Self-perception in physical performance has been documented to influence women to perform the exercise and physical activity. Therefore, this research aimed to identify and healthy women's self-perception and motivations to perform in a VO2max test. A total of 31 women (21.12 ± 2.01) completed the research. The study was divided into two principal tests. On the one hand, the measurement of a sub-maximal incremental stress test following established ASCM indications. Heart rate and ventilatory parameters were measured during the stress test using a metabolic measurement system and a gas analyser. After the test, the study sample completed the self-completed Healthy Lifestyle Questionnaire and the International Short Form Physical Activity Questionnaire (IPAQ-SF), and the Self Report of Reasons for Physical Activity (AMPEF). Correlation between VO2Max and average weight and body image (r = .001) was detected, showing the positive relationship between both values. The results obtained help confirm the importance of a positive self-perception in women regarding their weight and body image for better physical performance. Although these findings cannot be generalized, they establish a potential relationship between better physical performance and self-perception in most adults.Work carried out by Research Group, Pontifical University of Comillas, CESAG, Palma, Spain and SICA Research group HUM 564 (Expresión Corporal) Project PROMOTEX (University of Málaga)

Acute effect on working memory in trained university students: A continuous exercise in different environments

The associated benefits of physical exercise on cognition have been studied in terms of different variables. These benefits in natural environments have been studied during the last decades, and several investigations have shown contradictory results, it could be explained by the diversity of methodological variables that influence the results. The present study aims to analyse the acute effect of a 10 km resistance test in two environments (natural and artificial) on working memory, evaluated with the Digit Span Test. Thirteen highly trained University Students exceeded the inclusion criteria for the study, the methodological recommendations found in previous studies were implemented. The physical exercise intervention was running 10 kilometres at a rate of between 4.00 min/km and 4.10 min/km. This exercise was done in two circuits, in an artificial and natural environment. The subjective perception of effort and the control over the difficulty of the two circuits were controlled to confirm the same level of intensity. One-way ANOVA with Pre-Artificial Environment Condition (0.23 ± 0.16) and Post Artificial Environment Condition (0.94 ± 0.03)] revealed a significant main effect of environment condition, t (13) = 2.14, p < .05, d = 0.62. The results obtained showed how the natural environment produced significant improvements however, the artificial environment improved the results in the cognitive test, although not significantly. The results could be explained by the theory of restoration of attention that natural environments represent, confirming the hypothesis that the performance of physical exercise in natural environments produces an additional effect on working memory

Optimized automatic system to obtain ultrasonic radiation patterns

Due to the need to know and modify the radiation pattern of the ultrasonic sensors, to suit them to a particular application, in this paper is presented an automated measure system to obtain the radiation pattern for ultrasonic sensors in air. The system allows to obtain the radiation pattern in different conditions, for example for checking the characteristics of the ultrasonic sensors provided by the manufacturer, or for obtaining the modifications in the radiation pattern when a mechanical element is coupled to the ultrasonic sensor. In addition, the system has been improved by shortening the measurement time and decreasing the volume of data needed to carry out a measure. Furthermore, due to the fact of implementing the system inside a climatic chamber, the system allows to analyze the influence of environmental factors such as temperature and humidity, plus an evaluation of the degradation behaviour of the ultrasonic sensors in air under conditions of high temperature and humidity. At the end of the paper, two measurements have been done and the results have been compared with the characteristics of the radiation pattern provided by the manufacturer. Finally, a robust measurement system is presented, designed to find the modifications in the radiation pattern of an ultrasonic sensor when it is coupled to a mechanical element

Motivation and self-efficacy influence in the academic performance of Secondary students-athletes

The present study investigated the relationship between Academic Performance, Goal-orientations, Motivation, self-efficacy and Academic satisfaction. Seventy-four healthy secondary school students-athletes participated in the present research. The results showed correlations between the different variables analysed. Thus, we found a positive correlation between self-efficacy and qualifications, and task-goals with achievements-motive. However, the avoidance of negative judgments correlates negatively with task-goals and positively with inhibitor anxiety. Comparative analysis showed that were no differences according to gender, although significant differences were depending on the level of academic, mainly in ego-goals. Finally, another comparative analysis using the scores an independent variable, showed that students with higher grades presented more orientation to the goals-task and greater self-efficacy. The present study demonstrates a positive correlation between self-efficacy and ratings or score, task-goals, and achievements-motive. Thus, we can suggest an individualized study of each child where self-efficacy could be seen as a means of predicting new results
