Key to this is the development of investigative skills that make the investigative process feasible. This review was carried out under the PRISMA methodology, the objective of which is to know how research skills are developed in university students. It was determined that the main strategies, techniques and methods to develop investigative skills are those that promote collaborative work, the accompaniment of a tutor and feedback at the relevant times. Likewise, the main skills that a university student must possess is analysis, search and selection of information, reading and writing. It was concluded that the acquisition of research skills facilitates what and how to investigate, also that the studies reviewed do not have a precise diagnosis of the skills development process, that is, how students start and end.
The soil is essential for the survival of the human race, being a key piece to develop agriculture; however, the excessive use of chemical fertilizers that are incorporated into the soil with the intention of obtaining a more accelerated food production in the shortest possible time is causing crops to have to depend on ever greater chemical inputs, experiencing the degradation of the I usually. Therefore, new options are sought to improve soil conditions using organic fertilizers. The objective of the research was to determine the relationship between chicken manure and soil improvement in the Santa María Alta sector, Trujillo. The design was correlational, non-experimental and cross-sectional, some observation sheets and a survey of the 9 farmers were carried out, the result of the Spearman correlation coefficient is 0.756 with an approximate significance of 0.018. It is concluded that there is a high and significant positive relationship between chicken manure and soil improvement. Likewise, farmers feel satisfied with the production of crops planted in soils fertilized with chicken manure because it is good, profitable and ecological.
The investigation compared the variation of the water Quality of the Moche River basin (La Libertad) using the Water Quality Index-Peru (ICA-PE), based on the results of the National Water Authority in dry season (2013-2018). The investigation was descriptive, with a non-experimental design. In the methodology, 19 monitoring points were selected, the parameters that had the greatest significance of affectation and were within the ICA-PE were also chosen. The data was processed using the ICA-PE methodology and statistical analysis. The results obtained from the ANOVA analysis (5% ) showed significant variances in the parameters; In addition, the comparison of the data studied with the current ECA-Water (category 3 and 4) showed that only conductivity and boron comply with this; Regarding the ICA-PE in each point, its rating varied between Regular, Terrible and Bad in its majority, which allowed the elaboration of a recovery Management Plan proposal. Finally, it was concluded that the water of the Moche River basin is being contaminated, since the ICA-PE in most points indicated poor quality.
In Peru, an ally to counteract forest fires is the identification of vulnerable points in the event of a p o ssi b le disaster. The objective of this investigation was to diagnose by means of geographic information systems, the study of the ri sk and prevention of forest fires in protected natural areas of Cuzco. The analysis scope consisted of 6 protected natural areas, of which heat maps were obtained using the free software program Qgis in version 3.16.8, with specific radii according to their land area. The results express the identification of vulnerable points to a possible forest fire, locating them geographically within the defined radius, identifying them w i th the color range according to the risk matrix of the Manual fo r Risk Assessment of National Center for Disaster Risk Estimation, Prevention and Reduction (C E NEPRED), b ei ngthese with the highest concentration of heat and risk. before a possible forest fire.
The general objective of this research was to determine the production of organic fertilizer from the segregation of municipal solid waste in the district of Julcan, La Libertad in the year 2020-2021. The type of methodology is retrospective and has a longitudinal d esign approach. Likewise, we worked with the data reported by the Provincial Municipality of Julcan regarding its monthly production of solid waste. In addition, production data from the municipal solid waste characterization study was considered. Data was collected and recorded using the monthly compost production record card. The results show that the waste produced is divided into: non-usable (20.94%), inorga nic (21.61%) and organic (57.35%). From the use of the latter, it wa s obtained that the district has an average monthly production of 1.3 tons of compost. This production gives rise to different applications in improvement projects such as reforestation and agriculture. Finally, a proposal was formulated for a valorization plant based on the production of waste generated in the district of Julcan. In short, the purpose of thisproposal is to improve the management and valorization of the so lid waste produced.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
