    In a theoretical framework of game theory, one can distinguish between the noncooperative and the cooperative game theory. While the theory of noncooperative games is about modeling competitive behavior, cooperative game theory is dedicated to the study of cooperation among a number of players. The cooperative game theory includes mostly two branches: the Nash negotiation and the coalitional game theory. In this chapter, we restrict our attention to the latter. In recent years, the concept of efficient management of electric power has become more complex as a result of the high integration of distributed energy resources in the scenarios to be considered, mainly distributed generation, energy storage distributed, and demand management. This situation has been accentuated with the appearance of new consumption elements, such as electric vehicles, which could cause a high impact on distribution gridworks if they are not managed properly. This chapter presents an innovative approach toward an efficient energy model through the application of the theory of cooperative games with transferable utility in which the management, capacity, and control of distributed energy resources are integrated to provide optimal energy solutions that allow achieving significant savings in associated costs. This chapter presents a general description of the potential of the application of the theory to address Smart Grid, providing a systematic treatment

    We perform a detailed analysis of the solvability of linear strain equations on hyperbolic surfaces. We prove that if the surface is a smooth noncharacteristic region, any first order infinitesimal isometry can be matched to an infinitesimal isometry of an arbitrarily high order. The implications of this result for the elasticity of thin hyperbolic shells are discussed

    Dado que la realización de encuestas y entrevistas, así como las observaciones a clases, permitieron constatar insuficiencias en la preparación del docente de Ciencias Naturales en formación como un comunicador ambiental, y que ello limita su capacidad de rectorar la educación ambiental en la escuela, se definieron las características que debe poseer el mismo para cumplir con esta condición y se elaboró una alternativa didáctica que toma como base, potenciar el desarrollo de la comunicación, su cultura general integral, el enfoque interdisciplinario y la estrecha relación entre lo cognitivo y lo afectivo, de modo que pueda educar acertadamente hacia la conservación del medio ambiente.After surveys and interviews we carried out together with class observation, some inadequacies were verified in the preparation of the in-training Natural Sciences teacher as an environmental communicator which limits it their capacity to control the environmental education in the school. Some of the characteristics they must possess are defined to fulfill this task; therefore a didactic alternative was elaborated that is based on developing their communication skills, culture, interdisciplinary focus and link between the cognitive and the affective aspect. All this is done to eventually allow him to can wisely educate when approaching the environment in education

    Influence of a Multidisciplinary Program of Diet, Exercise, and Mindfulness on the Quality of Life of Stage IIA-IIB Breast Cancer Survivors

    Background: Integrative oncology has proven to be a useful approach to control cancer symptoms and improve the quality of life (QoL) and overall health of patients, delivering integrated patient care at both physical and emotional levels. The objective of this randomized trial was to evaluate the effects of a triple intervention program on the QoL and lifestyle of women with breast cancer. Methods: Seventy-five survivors of stage IIA-IIB breast cancer were randomized into 2 groups. The intervention group (IG) received a 6-month dietary, exercise, and mindfulness program that was not offered to the control group (CG). Data were gathered at baseline and at 6 months postintervention on QoL and adherence to Mediterranean diet using clinical markers and validated questionnaires. Between-group differences at baseline and 3 months postintervention were analyzed using Student’s t test for related samples and the Wilcoxon and Mann-Whitney U tests. Results: At 6 months postintervention, the IG showed significant improvements versus CG in physical functioning (p = .027), role functioning (p = .028), and Mediterranean diet adherence (p = .02) and a significant reduction in body mass index (p = .04) and weight (p = .05), with a mean weight loss of 0.7 kg versus a gain of 0.55 kg by the CG (p = .05). Dyspnea symptoms were also increased in the CG versus IG (p = .066). Conclusions: These results demonstrate that an integrative dietary, physical activity, and mindfulness program enhances the QoL and healthy lifestyle of stage IIA-IIB breast cancer survivors. Cancer symptoms may be better managed by the implementation of multimodal rather than isolated interventions.Background: Integrative oncology has proven to be a useful approach to control cancer symptoms and improve the quality of life (QoL) and overall health of patients, delivering integrated patient care at both physical and emotional levels.

    This study assesses genetic diversity and population structure of Quarter Horse, Azteca, Thoroughbred and Creole horses, frequently used for horse dancing competitions in traditional regional festivities. Since most animals in the studied area are used as breeders, the results support the improvement of management strategies, including periodical assessment of these populations to ensure acceptable population sizes and breed integrity, and documenting genetic flow and reproductive management.The South-Central region of Mexico has experienced a sizeable introduction of purebred horses for recreational aims. A study was designed to assess effective population sizes and genetic diversity and to verify the genetic integrity of four horse breeds. Using a 12-microsatellite panel, Quarter Horse, Azteca, Thoroughbred and Creole (CRL) horses were sampled and analysed for diversity and genetic structure. Genetic diversity parameters showed high numbers of heterozygous horses but small effective population sizes in all breeds. Population structure results suggested some degree of admixture of CRL with the other reference breeds. The highly informative microsatellite panel allowed the verification of diversity in introduced horse populations and the confirmation of small effective population sizes, which suggests a risk for future breed integrity
