Th e current study established the presence of Toxocara spp. eggs in public parks of the Jesús de Nazareno district in the Ayacucho Region, Peru. Th is study evaluated the presence of Toxocara spp. eggs, degree of upkeep of public parks, presence of fences, and also, verifi ed whether a correlation exists between the presence of these eggs and the presence of dogs and children in the parks inspected. It was determined that 90% of public parks in the district of Jesús de Nazareno are contaminated with Toxocara eggs, a 70% have low contamination and a 20% have a moderate contamination. As for the presence of perimeter fences, the absence of these fences was observed in 60% of cases, the Eta analysis found a low association (0.15) between the presence of fences and the degree of contamination. Th e correlation between the presence of dogs with the presence of Toxocara eggs was low. Finally, the largest concentration of children is found in public playgrounds, where there degree of contamination is low, indicating that the infection risk decreases but potentially always could mean a public health problem.

Th e purpose of this research aims to assess the prevalence of Brucella sp. in small and medium livestock cattle farmers in the district of Oxapampa, Chontabamba and Huancabamba province Oxapampa, department of Cerro de Pasco. Rose Bengal Test was used for the detection of Brucella sp. Antibodies. Of the 441 specimens analyzed by this study, none of them tested positive for Brucella’s antibodies, indicating the absence of the disease, that could represent a threat to livestock and public health, in the area. SENASA (National agricultural Health Service) is the responsible institution of the annual vaccination for the control and eradication of the disease.

In the process of educational quality, several higher education institutions have shown concern for the satisfaction of their students, in order to know their expectations and opinion of the various parameters of the study, development and improvement plans, according to the evaluation or self-assessment models. Th e present work was carried out with the purpose of knowing how satisfi ed students are with the Biology degree at Ricardo Palma University, Lima, Peru. Such as the sequence of courses, teaching methodology, basic and specialty training, content of subjects, teaching strategies, subject assessment, library use, learning and performance. A survey was designed and applied to 63 students from the 7th to the 9th academic year in the semester 2015-II, whose results are presented generally in the categories, level of percentage satisfaction index Th e analysis of the information determined that 67% of the students are satisfi ed with the 2006-II curriculum, being their best appreciation in the achievements and performances with respect to the area of biodiversity, and their lower satisfaction in the area of ecology and environment; Th is indicates that a revision of the curricular plans and improvements in the respective plan are needed.

In recent years, the scientifi c community is becoming increasingly interested in the knowledge of the biology of spermatogonia. Th is mini-review aims to announce the progress made in the origin and migration of primordial germ cells, their propagation and renewal, in vitro culture methods as well as the perspectives of the use of spermatogonial stem cells (SSCs) of mammals, mainly in regenerative biology. Mammalian spermatogonial stem cells are a population of cells that are found in very small amounts at the periphery of the seminiferous tubules, from which spermatozoa are produced continuously, throughout the life of the males. Th e SSCs, are the unique adult stem cells that, at this biological complexity level, can be recognized it which allows to deepen investigations about its organization and functions in biological models, diff erent from the most studied mouse, such as humans, cattle, canines, for the importance of its knowledge in the use of strategies in reproductive biotechnology and in regenerative biology.

Th e bird diversity of the Ricardo Palma University campus was studied through continuous sightings with the aim of developing an inventory of birds that are distributed on the campus, in addition to indicating their trophic guild and compare this study with similar campuses of Peruvian universities. Th e bird species richness was 22, that belong to 15 families grouped in 8 orders. Most species belong to the order Passeriformes. Th e most representative trophic guild was the granivore. In addition, the observed richness of species, families and orders with similar campuses of Peruvian universities was compared. Th e campus of the Ricardo Palma University is considered an interesting bird watching point within an urban ecosystem.

At the local level, in Manta there is little or no information on the conservation status of birds and the number of species that exist, since wildlife monitoring is restricted to the protected areas of the province, without taking into account the ecological synergy that exists outside these spaces. Therefore, the objective of this article is to determine the abundance and diversity of the boreal migratory avifauna on Tarqui beach. The study area is located on the beach of Tarqui, in the city of Manta, Ecuador, specifically from the market for the commercialization of fishing products "Playita Mía" to the mouth of the "Río Manta-Burro" and the artificial rocky area that limits with the sector known as "La Poza". The study area delimited on the bird watching route is approximately 1 km. long, variable width that includes the sea, and is intervened by a wide range of human activities. Differences are observed between the number of species in the Tarqui Beach study area, which has a maximum number of species of 17 and a minimum of 11 with respect to the protected area known as “Isla Corazón y Fragata”. Keywords: birds, fauna, beach, index, abundance.

Communication is defined as an opportunity for meeting and exchanging information with others, this poses a wide range of possibilities for social interaction, since through it you can achieve understanding, coordination and collaboration between different actors within an organization for its development and growth. This research aims to review the conceptualization of the aspects that govern the internal communication process in universities. Thus, university communication once again assists the doctrinal sources that it has traditionally liked. Above all, organizational communication, which over the last half century has managed to treasure a set of knowledge that has guaranteed the effective performance of that professional activity. It was learned that the media have become privileged areas of public spaces to provide information, propaganda, advertising and consensus, with the purpose of expanding a corporate culture. Keywords: institutional communication, communication plan, media.

This project was carried out in order to use the residual milk whey from the processes of the lactic industries of the sector, located in the province of Manabí, canton Santa Ana, as raw material for obtaining lactic acid, for which purpose, it was carried Carry out the calculation of the annual potential demand in Manabí ($ 23,360) representing this value 16% of the national demand, covering 10% of the lactic acid market. Subsequently, a bibliographical investigation was carried out to evaluate the production of lactic acid, a yield of 8.3% of lactic acid was determined from the fermentation of the whey using the bacterium lactobacillus bulgaricus as a microorganism. Then the elaboration of the sizing of the equipment that the plant will use for the production of lactic acid was carried out, avoiding the oversizing of the equipment that increases the cost of production. Each one of the equipment has its technical data sheet which shows its capacity, dimensions and energy required for its operation. Finally, an economic proposal was made which includes the price of the equipment necessary for the implementation of the plant, it also consists of the annual expenditure made by the inputs used in the industry, thus giving us an idea of the investment required for start-up of a plant at this scale. Keywords: lactic acid, whey, fermentation, lactobacillus bulgaricus, AutoCAD.
