El presente estudio propone el uso de residuos sólidos orgánicos para el aprovechamiento de estos mediante técnicas factibles que puedan convertir el material en adsorbentes para la remoción de metales pesados provenientes de los efluentes residuales de la industria textil. Específicamente de las actividades que realiza la empresa “La Grande” en Junín. Siguiendo los antecedentes se brinda la propuesta de trabajar con materiales de desecho de esta manera dándoles un uso adecuado y sostenible, a un menor costo de tecnologías más avanzadas que son eficientes pero requieren de un significativo financiamiento.Al finalizar el estudio se concluye que la cascara de naranja tiene un gran potencial de uso para la remoción de metales pesados de efluentes al convertirlos mediante procesos físicos en materiales adsorbentes.

The research work that is presented was developed with the objective of verifying the influence of playful strategies on the development of fine motor skills in children from an initial educational institution. It is an investigation carried out from the quantitative approach, of an experimental type and specified in a pre-experimental design. Likewise, for data collection, the observation sheet was used as an instrument, which was applied to a sample of 20 children of 5 years of age of the initial education level. The statistician used for the corresponding hypothesis test was Wilcoxon as it is ordinal scale data. The results obtained as a result of the research carried out allow us to conclude that playful strategies significantly influence the development of fine motor skills in 5-year-old children of the initial education level, a result that is corroborated with the level of signifi...

Objective: (i) Analyze the effect of altitude above the sea level on the mortality rate in patients undergoing invasive mechanical ventilation. (ii) Validate the traditional equation for adjusting PaO2/FiO2 according to the altitude. Design: A prospective, observational, multicenter and international study conducted during August 2016. Patients: Inclusion criteria: (i) age between 18 and 90 years old, (ii) admitted to intensive care unit (ICU) situated at the same altitude above the sea level (AASL) in which the patients has stayed, at least, during the previous 40 days and (iii) received invasive MV for at least 12 h. Material and methods: All variables were registered the day of intubation (day 0). Patients were followed until death, ICU discharge or day 28. PaO2/FiO2 ratio was adjusted by the AASL according to: PaO2/FiO2 * (barometric pressure/760). Categorical variables were compared...
