The inadequate treatment of urban waste in landfills represents an environmental risk for agricultural soils where their edaphological properties can be modified. The aim of the study was to evaluate organic matter and pH in agricultural soil in front of the Quitasol dump in the city of Abancay, Apurímac, Peru. Three sampling points (PM1, PM2, PM3) of the agricultural soil where organic matter (OM) and pH were determined were selected by means of a random probability sampling. The results were: PM1 (MO = 1.69%; pH = 7.05), PM2 (MO = 1.12%; pH = 7.06) and PM3 (MO = 0.30%; pH = 7.26). The percentage of OM ranged from the medium to low range where there were statistically significant differences between the three sampling points. The pH values were on the neutral scale. It is concluded that the use value of the agricultural land near the Quitasol dump is limited according to the organic ma...

El tratamiento inadecuado de los desechos urbanos de los botaderos de residuos sólidos representa un riesgo ambiental por las modificaciones subyacentes que pueden generarse hacia los suelos; de modo que, la sistematicidad evaluativa sobre las propiedades físico-químicas permite prevenir cualquier alteración relacionada con su valor de uso. El objetivo del proyecto fue evaluar propiedades físico-químicas, plomo asimilable y valor ambiental del suelo agrícola ante exposición al botadero de Quitasol en Abancay, Apurímac. En noviembre de 2017 y febrero del 2020 se seleccionó mediante un muestreo probabilístico aleatorio, tres muestras de suelo agrícola. En condiciones de laboratorio se determinó, la materia orgánica mediante el método de Walkley-Black, el pH se registró con el equipo Hanna Hi 2898 y el plomo asimilable se cuantificó por espectrofotometría de adsorción at�...

The absorption of heavy metals by growing plants is an environmental problem for human consumption. The aim of the study was to describe the biological absorption coefficient in Zea mays due to lead exposure in the Quitasol solid waste dump in Abancay, Apurímac, Peru. Three sampling points (PM1, PM2, and PM3) of the agricultural soil where the biological absorption coefficient (BAC) was determined were selected through a random probability sampling, through the relationship between the concentration of assimilable lead in the root and the concentration of assimilable lead in the soil. The BCA ranged from 0.06 to 0.91 where there were statistically significant differences between sampling points 1 and 3 compared with 2. It was observed that the CAB concentrations were higher than the value 0, which indicates that the plant is absorbing lead and could produce phytotoxicity effects in Z. m...

El propósito del estudio fue evaluar el aprendizaje de procesos metodológicos mediante prácticas evaluativas en docentes universitarios. Se fundamentó una experiencia mediante los módulos: investigación científica con enfoque cualimétrico y redacción de artículos científicos impartidos durante el Diplomado Internacional ¨Creatividad Científica e Innovación Tecnológica¨ que se desarrolló desde junio a diciembre del 2018 en la Universidad Nacional ¨San Luis Gonzaga¨ de Ica, Perú. Se aplicó a 50 docentes un examen de entrada con base en siete (7) preguntas agrupadas en dos tipos de test psicolaboral: 1ro), de rapidez y 2do), de lápiz y papel donde se midió el porcentaje de inclusión según los intervalos de puntuación: 20–16 y 15–11. Se consideró, dos niveles de respuesta: inmediato (1 a 15 minutos) y demorado (16 a 30 minutos). El mayor porcentaje de docentes ...

Every recognizable and competitive result is based on interactive cognitive actions so that universities base their social responsibility on the dynamics of professional recognition and its realization in research projects. The purpose of this study was to evaluate the collaborative communication of teamwork as a key indicator in scientific research. Three general questions were asked: 1st) Who knows what you do to the ones you know?, 2nd) Who of you recognizes the scientific knowledge about what you do to the ones you know? and 3rd) How many of you recognize the scientific contribution of those who recognize your scientific work? The questions were indicated in three graduate training programs where the low percentage of recognition interpreting possible difficulties on the scientific policy was measured; for this, the Likert-type scale technique was applied where 4 aspects were conside...
