The present investigation was to evaluate the behavior of two constructed wetlands in series with Phragmites australis for the treatment of domestic sewage. The wastewater source was captured drainage network of the Universidad Nacional Agraria La Molina. The wastewater was conducted by pipes to a sedimentation tank and cylinders and subsequently distributed to two reservoirs installed in series planted with Phragmites australis : A Horizontal followed a vertical marsh swamp. The porous medium marsh consisted of gravel and sand substrates . The marshes were operating with subsurface flow under conditions of continuous power . Performance monitoring of the treatment system was conducted during the months of November 2000 and January 2001, with weekly sampling . In analyzing the behavior of TSS and BOD5 in the horizontal marsh A removal of 97.2 % and 79.6 % were obtained. The horizontal sw...

The objective of the professional sufficiency work was to evaluate the characterization of bovine production systems in the district of Barranquita-San Martin 2018. The results indicated an average livestock experience of 37 years and the farms have between 67-120 has with cut grass (Pennisetum purpureum Schumach) 20 has and 42-92.25 has/fundo of natural pastures such as torourco (Axonopus compresus, Paspalum conjugatum and Axonopus guianensis). The construction of stables varies between 0.25-0.75 ha/farm and warehouses and silos between 0.25-0.50 ha/farm. The cultivated or monoculture areas are 8-30 ha/farm and the forests are 10-30 ha/farm. The improved pasture is Brachiaria brizhanta, with 3-6/pastures/fundo. They use electric fencing and barbed wire for animal control. Meat and milk are produced; the average age at first service is from one year and eight months to two and a half yea...

Antecedentes.- La parasitosis intestinal en los niños constituye un problema de salud pública que debe ser valorado periódicamente. La incidencia, intensidad y prevalencia de los parásitos es mayor que en los niños que en los adultos, debido posiblemente a la falta de resistencia natural o adquirida y a las diferencias de comportamiento y hábitos. Objetivo.- Identificar la prevalencia del parasitismo intestinal por microscopia directa en materia fecal y su relación con las características epidemiológicas de los niños menores de cinco años del albergue Casa de la Niña de Loreto 2015. Metodología.- El estudio es de tipo descriptivo de corte transversal, el universo estuvo construido por 120 personas menores de cinco años. Los representantes firmaron el consentimiento informado, previa aplicación de la encuentra que contenía datos de DNI e información relacionada con las va...
