How to approach higher education for training in applied research in a "change of epoch" where knowledge has become a substantial asset to the generation of value in goods and services in organizations? What strategy should be implemented when its efficiency tends to be measured through mechanisms external to the research areas of the university? Two questions that allow, on the one hand, going the traditional way in which the university reiterates trivial mechanisms for engineering research training, and, on the other, the holistic -systemic-cybernetic- approach that promotes this same training in the context of complexity. This paper reviews the experience in the field of engineering, emphasizing the educational strategy aimed at achieving an insight of knowledge, where the university is facing increasing difficulty in setting the direction of the areas of applied research in engineeri...

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.

Abstract: To answer the question, and then what? it is first necessary to ask ourselves how we appeared on Earth and how we got to where we are; then to answer what happens today; and, finally, to try to establish how our disturbed human system might unfold in the future. Development and preparation of this document use a complex systems perspective. The link between human system components is considered as a social energy that can unite or repel. The greater the cohesion energy, the greater the adaptive capacity of the system; its continuity implies transformation. Entropic energy leads to collapse. The human system historical deployment has generated changes in the predominance of cohesion and repulsion energies that have manifested themselves in the pattern of bonds., Entropic energy has been enhanced with the appearance of the COVID-19 pandemic. The same goes for the growth of mental...

This article aims to take out guidelines for addressing future pandemics from the recognition of the close relationship between nature and society through the application of the complex adaptive systems approach. From the review, it is concluded that the adoption of the complex adaptive systems approach allows assuming the complexity paradigm when addressing pandemics, reinforcing the reductionist systems approaches that, while it is true that they respond in cause and effect linear situations, they have limitations when facing phenomena with the characteristics of complexity: self-organization (emergency), non-linearity (chaos), adaptation-evolution (cybernetics) and interconnectivity (network structure), among others. From the approach of the complex adaptive systems and the socio-ecological systems, it is possible to understand the close interrelationships and interdependencies betwee...

10 April 2016 will be the presidential election in Peru. The media will cover the activities of the leading candidates and rummage in their resumes. In this process, the press will be tempted to use propaganda techniques, a category traditionally associated with political actors. For example, they may appeal to stereotypes, express their opinion through seemingly independent sources and select facts to build an ideological discourse. For its part the press agents of candidates and political marketing experts are hunting for journalists.

Peru maintains a leading position in the world mining in connection to production and extraction of metals like copper, zinc, silver, gold among others. Geological exploration and prospecting already carried out, show us a promissory future for the above mentioned minerals and other interesting findings like nickel in millerite ore which was proved in some ore deposits of the Marañón geological complex. This occurrence allowed us to carry out metallurgical investigation, specifically hydrometallurgical processing for the Peruvian sulphide ore aimed to the development of profitable mining operations for both private sector and the Peruvian state. We showed the metallurgical test results carried out at the metallurgical engineering school related to obtaining metallic nickel plates and its by products like cement and sulphate crystals.

Prospective studies developed in the zone of the Marañón basin show us a type of regional geology called the Marañón-Huánuco Region Complex, consisting of metallic minerals of Copper, Silver, Gold in schists and gneiss in contact with intrusives, as well as minerals of nickel, cobalt, titanium, platinum, among others. The characterization of the minerals in the area using instrumental techniques: minerographic microscope, Mössbauer spectroscopy analysis, multielemental chemical analysis, allow us to corroborate the presence of the metallic minerals of the Marañón Complex, as well as the presence of iron oxides, and to a degree of magnetization that are indicators of the metallic presence in the sampled areas. Metallurgical tests carried out indicate a good metallurgical recovery of the concentrates obtained for the chalcopyrite ore, which indicates a good economic possibility for...

Backgrounds: this theoretical article reviews empirically and in detail the concepts of well-being, optimal/positive mental health, types of well-being and flourishing, with a view to clarification and differentiation based on what the current scientific literature offers, and given that they are often used as synonyms, or as interchangeable terms. State of the art: various criteria of inclusion and reference of what we usually consider "positive" and "negative" in scientific studies of well-being and distress (disease, pathogenic, decay) are explained and proposed as a framework and reliable guide for future research and work methodologies related to the constructs studied here, as well as a means of support in the elaboration and enrichment of the same definitions. In addition, specific and differentiated concepts of well-being, optimal mental health and flourishing, which are recogniz...

The aim of this study was to evaluate the effect of a parenteral treatment with vitamins and minerals on the percentage of pregnancy in heifers after a fixed-time artificial insemination (FTAI) scheme as well as to determine possible relationships between the response to the treatment and the Reproductive Tract Score (RTS). A total of 360 heifers from three farms were used (A, B and C). On day 0, the animals were divided into two groups according to their RTS. A group was supplemented via i.m. with a commercial vitamin-mineral complex (V+M Group) and the other one remained as a control group. Simultaneously, an intravaginal device with 0.5 g of progesterone was placed and 2 mg of estradiol benzoate was injected. On day 7, the device was removed and 500 µg of D(+) cloprostenol and 1 mg of estradiol cypionate were injected. The FTAI was performed between 48 and 56 h after the device was r...

Plants have an innate immune system that is organized at two levels: one on the surface of the cells and another in the cytoplasm of the cell. Receptors on the cell surface are involved in the first line of defense, triggering immune responses by perceiving immunogenic patterns that occur during pathogen invasion. The Cf-4 receptor, present on the cell surface of tomato, requires the presence of the co-receptor SOBIR1 to confer resistance to strains of the fungal pathogen Cladosporium fulvum that secrete the Avr4 effector protein. This interaction triggers an immune response that includes a form of programmed cell death known as the hypersensitive response (HR). This thesis explores the early signaling events triggered by the cell surface receptor Cf-4, using the solanaceous model plant Nicotiana benthamiana. Furthermore, a novel method to visualize and quantify HR intensity is presented...

I present in this article the results of survey and mapping at sites with early monumental architecture in the Middle Fortaleza Valley. Architecture provisionally assigned to the Late Archaic period is analyzed, and some hypotheses on its development are proposed. The Fortaleza sites are then compared with other ones throughout the North Central Coast. I propose that the architectural complexes in this region seem to correspond to local-range sociopolitical entities, instead of large, regional polities. Finally, I conclude with some thoughts on new theoretical perspectives to understand the origins and development of such entities.

El presente artículo trata de la formulación de una propuesta de las Ciencias Forestales para la vida. El propósito es enriquecer el marco teórico y operacional de las Ciencias Forestales a partir de los enfoques de la complejidad, y así ampliar su campo de actuación e impacto en la sociedad. Para el efecto se realizó una revisión bibliográfica especializada y se complementó con el propio proceso reflexivo del autor que viene desarrollando sistemáticamente una línea de investigación en clave de filosofía forestal. De la revisión y reflexión se concluye que las Ciencias Forestales se corresponden con la ciencia normal, por la cual tiene un marco positivista, objetivista, lineal y universalista. Esta forma de hacer ciencia ha sido fundamental, y lo seguirá siendo, pero presenta limitaciones frente a la realidad compleja que presenta problemas de frontera, cuyas soluciones ...

The objective of the study was to determine the factors associated with QRS complex alterations in domestic dogs undergoing electrocardiographic examination at a cardiological diagnosis center in Lima during the period 2018-2020. An analytical observational study was carried out. A data collection form was used to record information about the dependent variables: duration, amplitude, polarity and morphology of the QRS wave; and the independent variables: age, sex, breed size and obesity of the dog. Subsequently, a logistic regression analysis was performed to quantify the association between the classification variables and QRS complex alterations. The results showed that adult dogs were 1.74 times more likely to present QRS complex lengthening, and geriatric dogs were 2.14 times more likely to present alterations in the duration of this electrocardiographic variable compared to young do...
