The research study was conducted on a sample of pyrite-silver tailings provided by the Administrative Company Cerro S.A.C. located in the Simón Bolívar district, province and region of Pasco. The importance of research contributions for its best treatment of this material is due to the fact that it has a stock of one million tons with an average grade of 5,14 ozAg / t and another two million with a grade between 5 to 6 ozAg / t. The latter have not had any previous treatment, therefore, it is expected to determine the appropriate method to optimize the recovery of silver in this pyrite-silver complex mineral. The recovery of silver in this complex mineral by the flotation method reached 20 %, leading to define it as a refractory mineral to this process, therefore, it is a matter of investigation other processes such as leaching. From the evaluation of the results of the leaching tests,...

In the 21st century, the Psychotherapy continues to take giant steps with a comprehensive perspective. The areas of the current challenges of Psychotherapy are numerous, this article presents only one of them, the study of the relationship between Complex Trauma, Attachment and Dissociation. Many international colleagues such as Van der Hart O, Nijenhuis E, Steele K., Van der Kolk B., Pelcovitz D., Roth S., Mandel F., McFarlane A., Herman, J., inter alia , have given a great scientific contribution that helps us to generate a better dimensional and categorical diagnosis following the new indications of the DSMV, but more important , they indicate that the way to solve a problem that a patient brings us is not only one, it means there is a greater demand for those who work in the clinical area and especially in Psychotherapy, an update and constant study of new intervention approaches.

In the article published by Huamancayo-Espíritu and Pérez-Cárdenas on the consumption of fruits and vegetables in medical students, the authors estimated a prevalence of low consumption of fruits and vegetables of 60.1% in a sample of 371 students. The most frequent reasons found were the difficulty of obtaining them in the university cafeterias, insufficient time for their selection, purchase and preparation and the fact of living with their father or mother who is in charge of their feeding; the second being the only associated factor, and the last being a protective factor. The study has many strengths, among which the importance of the thematic axis that it develops stands out: healthy lifestyles are one of the great determinants of health, highlighting that one in every 5 deaths in the world is associated with unhealthy eating.
