The instability caused by fluid leakage leads to limited performance in turbomachines. This instability may be improved by using flexible bearing supports with anisotropic stiffness. With a simplified model this effect is investigated, including the influence of many parameters. The results show that the optimum range of anistropy is strongly dependent on the parameters of the rotor-bearing system. In this paper an explanation from an energy point of view is presented to clarify the different stability behaviors with anisotropic bearing support.

Actualmente,   la obesidad es una de las enfermedades nutricionales que afectan con gran significación la población ecuatoriana y en especial la manabita y esto se debe a lo variada que resulta la gastronomía en la provincia, partiendo de esta idea, se desarrolló esta investigación, especialmente con el objetivo de realizar una revisión bibliográfica que resumiera  los  aspectos  más  importantes  relacionados  con  los  riesgos  que  implican  el sobrepeso y la obesidad desde el punto de vista energético y también para caracterizar la situación actual de la población representada por los estudiantes que cursan el primer año de bachillerato en la Unidad Educativa “ITSUP”. Para ello se utilizó la población adolescente de los estudiantes que cursan el bachillerato en cualquiera de sus modalidades de la institución antes mencionada. Se llevó a cabo un control antropométrico de peso/talla de los estudiantes antes señalados, con la finalidad de poder evaluar, calcular  y sacar el diagnóstico del índice de masa corporal   de ingreso   de cada uno de ellos. Se concluyó que el síndrome de la obesidad se debe a varias causas y factores, como el cultural, el amplio surtido de alimentos en la región, y lo económico que éstos resultan; se concluye además  en que una cuarta parte de los adolescentes del instituto, presentan un peso por encima del adecuado.  Palabras claves: Obesidad, sobrepeso, riesgos, balance energético, nutrición Risks involved in overweight and obesity for health from the energy point of view Abstract  Nowadays,  obesity  is  one  of  the  nutritional  diseases  with  great  significance  on    the Ecuadorian population and especially the Province of  Manabi and this is due to the varied cuisine resulting in the province, based on this idea, this research was carried out, especially in order to perform a literature review to summarize the most important aspects of the risks involved overweight and obesity from the energy point of view and also to characterize the  current status of the population represented by the students in the first year of bachelor of Education Unit "ITSUP". For this adolescent population of students in the school in any of the aforementioned modes institution was used. Conducted an anthropometric control weight / height of the students mentioned above, in order to be able to evaluate, calculate and make the diagnosis of body mass index entry each. It was concluded that the syndrome of obesity to various causes and factors, such as cultural, the wide range of food in the region, ; It is also concluded that a quarter of high school adolescents, have a weight above adequate.  Keywords: Obesity, overweight, risk, energy balance, nutrition

The industrial component under loading change its mechanical characteristics by stress. It is very important to make clear the distribution of the applied stress in the component to reduce the failure. In this paper, magnetic Barkhausen noise (MBN) method is used to evaluate the stress of DC01 steel. Combined with theory for both magnetic domain and magnetization, this work analyzed MBN signal from energy point of view. Magnetic strength corresponding to the maximum MBN shows a downward trend with the increase of tensile stress. Plots of energy against stress showed a relationship providing a convenient method for detecting stress levels by MBN.

Active mobility has been described as a healthy action, it also contributes to diminish climate change and improvethe air quality. Research the advertisements in the roles of mobility from anenvironmental and energy point of view is highly relevant. In this analysis the bicycle appears as an added element, from company campaigns to institutional advertising, and also of specific advertisements where bicycles are directly marketed. This study had as objective to provide a novel analysis of adverting regarding bicycle and mobility. A quantitative and qualitative analysis has been carried out based on diverse publicizing documents spread during the last twenty years. Based on the analysis, the results showed how the role of the bicycle presented in publicity not related about mobility seems to be equal better communication between people, transport, fun and healthy element good and bad practices identified and analyzed in both corporate and institutional campaigns. Also, some bicycle advertisements reuse the slogans for automobiles, focusing on gadgets or design. Based on the analysis, it would be wise to insist on the development of communication guides that focus on the bicycle as an element of the smart city, electric mobility, zero emissions vehicle and healthy transport, both from individual and collectivebeneficial perspective.
