This cross-sectional descriptive quantitative research was performed from November to December 2012, in 80706 High School, in order to determine the relationship between, self-esteem levels, family functioning and, snuff and alcohol consumption in teenagers. The universe consisted of 177 people, of which 30 were chosen for the sample, according to established inclusion criteria. For data collection we used the Coopersmith self esteem test and scale Olson Family Functioning. Data were tabulated and presented in statistical tables of single and double entry. The analysis of the relationship between the study variables was performed by Chi square test (X2). In the discussion of the results we concluded that:The 1.7 percent have low family functioning, the 7.9 percent median family functioning and family functioning 90.4 percent higher. 4.6 percent have low self-esteem, 19.1 percent lower mi...

El presente estudio de investigación es con enfoque cuantitativo de tipo Descriptivo – Correlacional y de diseño metodológico no experimental, de corte transversal. El estudio está conformado por una población conformada por 154 estudiantes de enfermería de ambos sexos de la Facultad de Enfermería de una universidad de Trujillo. En el estudio se utilizó los cuestionarios de percepción y actitud hacia la investigación en estudiantes de pregrado de enfermería. Este instrumento fue tomado del trabajo de investigación realizado por Condori Chacón quien lo validó por varios jueces expertos dando una confiabilidad de 0.854 mediante alfa de Cronbach,, este instrumento fue modificado y adaptado por nosotras las autoras y sometido a prueba de confiabilidad la cual se utilizó pruebas estadísticas de fiabilidad (alfa de Cronbach = 0.848), los datos obtenidos fueron tabulados y pre...

The productive sustainability of Pennisetum clandestinum in the Peruvian highlands was evaluated through productivity, growth and chemical composition. The effect of the nitrogen (N) rate, organic matter application, and cutting frequency on Kikuyu grass's yield, chemical composition, plant height, and growth rate was investigated. Experimentation followed a randomized block design with split plots. Multivariate analysis of variance (MANOVA) assessed differences across study factors. Applying 120 kg of N ha-1 yr-1 raised the protein yield to 3454.53 kg ha¯¹, with a crude protein (CP) content of 23.54%. Moreover, cypress (Cupressus lusitanica) trees influenced the Kikuyu biomass, producing 19,176.23 kg of dry matter (DM) ha-1 yr-1 at 8.5-11.5 m from the tree base. Organic matter enhanced Kikuyu aboveground biomass. While dry matter production showed no significant difference between 30-...
