Revisamos sistemáticamente el proceso de producción de di-muones vía la dispersión de neutrinos en el campo Coulombiano del núcleo, conocido como producción tridente de neutrinos. A pesar de que este proceso tiene una sección de choque pequeña comparada con el proceso de dispersión neutrino-núcleo vía corriente cargada inclusiva en el Modelo Estándar, se caracteriza por una señal experimental muy clara. El par de muones cargados opuestamente es caracterizado investigando sus distribuciones cinemáticas. Para esto, hemos implementado una simulación detallada del proceso de producción tridente de neutrinos en el generador de eventos Montecarlo GENIE; y analizamos y simulamos los backgrounds relevantes. También exploramos métodos de Análisis Multivariado para mejorar la selección de la señal en el contexto de detectores tipo MINERVA y DUNE como representantes de experime...

Corporate Social Responsibility (CSR) can be defined as a responsible way of doing business and the impact these operations have in the economy, the society and the environment. Nowadays, companies use different avenues to communicate CSR initiatives. Social Media platforms are one of the important resources to communicate CSR. This paper performs an empirical analysis of frequency, content, and feedback of CSR messages presented on social platforms (Facebook and Twitter) of 50 companies from the Fortune Magazine. Results showed that in spite of the great resources available for CSR online communication, companies are still in its infancy in promoting a two-way communication process. In order to resolve this problem, this paper proposes a theoretical framework for CSR communication through social media.

The climatologically changes that involve the global heating, have produced in the last decades a great reduction of glacial areas on earth, and this is evidenced by the glacial back stripping The area of study is situated into a seismotectonic zone where an intercordilleran segment has a Cordillera Blanca’s glaciers, that produces a lot of ice2 s falls, moraines landslides and great rocks. These materials fall in to glacial lakes and produce a violent damage. Huaraz city is in the Quilcay2 s alluvial fan, and consists of the fluvial-alluvial sediments Historically in Huaraz have been reported events like landslides that evidence the risk factor and increase the vulnerability of the zone due to deglatiation and lacustrine phenomena’s of Palcarraju mountain and Palcacocha lake. For the mitigation of the risk we are showing some instructions that must be diffused to the most of the peo...

Digital Image Processing (DIP) books teach algorithms to digitally operate on images and include some figures to show the effects of those mathematical tools. In this report the creation of Imagery, a Virtual Laboratory for computer-assisted education (teaching and learning) of DIP is reported. Imagery can be used in the classroom, in the laboratory or at home. This software was developed to be used as a DIP laboratory, allowing the user to experiment with DIP algorithms, enabling him to see their effects on his own images. In the classroom Imagery helps the teacher in the exposition of the DIP topics he is covering; in the laboratory, Imagery can be used to carry out experiments supporting the topics covered in class; at home, this Virtual Lab can be used by the student to practice and thus reinforce the knowledge acquired in class.

This essay is a first approximation to the study of Hipolito Unanue’s thinking influence on the Peruvian epidemiology discourse construction. After describing general aspects of Unanue’s thought on the processes of disease propagation, we discuss how at the beginning of the XX century, in middle of the debate on the community problems and the various possibilities of the nation’s development, different authors retake Unanue’s ideas, who had already been raised up as a cultural hero of the medical community. We analyze his influence in the work of intellectuals like Paz Soldan, Olaechea and Lastres analyzing the diverse particularities of their thinking decodifying process and how this allowed the development of an identity process linked to the making of a ‘Peruvian conscience’, that is, of a particular way of seeing and transforming the world. This systemic way of approachin...

Mining and metallurgical activity produces liquid effluents as a waste during the extraction process, which must be treated in order to be disposed in the environment, following governmental and environmental legislation. Big and medium size mining industry carry on environmental projects as it is the trend worldwide, but small size and informal mining did not have between its priorities the environmental issue due to the lack of research on clean technologies related to this sector which finally could influence in make more efficient its processes. The main aim of the research is centered on propose solutions with an experimental basis for design and dimension of containers in processes with chemical precipitation and cementing of dissolved metals in liquid effluents. Laboratory tests are detailed for cementing copper from liquid effluents by means of light scrap iron which allows recov...

A framework for pricing Asian power options is developed when the underlying asset follows a jump-fraction process. The partial differential equation (PDE) in the fractional environment with jump is constructed for such option using general Itô's lemma and self-financing dynamic strategy. With the boundary condition an analytic formula for the option with geometric average starting at any time before maturity is derived by solving the PDE and the option with arithmetic average is evaluated in Monte Carlo simulation using control variate technique with the help of the above analytic solution. Overwhelming numerical evidence indicates that the technique proposed is computationally efficient and dramatically improves the accuracy of the simulated price. Moreover this study will pave a novel way to copy with the option contracts based on thinly-traded assets like oil or currencies or intere...

This article presents reflections on thinking and how it can be enhanced to generate projectual memory applied to the creative process. Thus, design situations, although challenging, will not represent an insurmountable peak of stress. The incorporation of Artificial Intelligence in the process provides feedback that encourages the enhancement of projectual thinking. Thanks to the fact that it makes it possible to visualize the process and ideas that allow the designer to manage, and/or create, tools to successfully approach any situation by returning to the thoughts and inputs used. The path to approach empowerment will be like this: review the faculty of thought; next, approach the projectual in the architectonic. Then, with the sections about conceptual and schematic inputs, communication and the creative process, the journey is consolidated.
