A Comparison of the Environmental Impact of Different AOPs : Risk Indexes

Today, environmental impact associated with pollution treatment is a matter of great concern. A method is proposed for evaluating environmental risk associated with Advanced Oxidation Processes (AOPs) applied to wastewater treatment. The method is based on the type of pollution (wastewater, solids, air or soil) and on materials and energy consumption. An Environmental Risk Index (E), constructed from numerical criteria provided, is presented for environmental comparison of processes and/or operations. The Operation Environmental Risk Index (EOi) for each of the unit operations involved in the process and the Aspects Environmental Risk Index (EAj) for process conditions were also estimated. Relative indexes were calculated to evaluate the risk of each operation (E/NOP) or aspect (E/NAS) involved in the process, and the percentage of the maximum achievable for each operation and aspect was found. A practical application of the method is presented for two AOPs: photo-Fenton and heterogeneous photocatalysis with suspended TiO2 in Solarbox. The results report the environmental risks associated with each process, so that AOPs tested and the operations involved with them can be compared

The Attitudinal Style as Pedagogical Model in Physical Education

[EN] The continuous changes in the different legislative systems have led to the application of different ways of understanding students and generating learning in them. In this sense, an area such as physical education is not alien to the continuous changes in teaching learning and its teaching has been modified from a behavioural approach to more cognitive perspectives. In this line, the Attitudinal Style concept arises with the intention of responding to this need for evolution, a global approach to teaching, as well as the generation of materials that allow the participation and learning of all types of students, greatly favoring their involvement and/or adaptation. The objective of this study is to present the Attitudinal Style as a pedagogical model within school physical education, analyzing its characteristics, elements and main purposes. A systematic review of narrative character is used, showing the origins and fundamental elements to justify the Attitudinal Style as a pedagogical model. Thus, aspects such as the generation of positive experiences in the students; the rigorous explanation of what is being learned, adaptation to the content, context and students; the work of collaboration and/or cooperation as a means to achieve a group achievement; the transfer of learning; and the application of formative evaluation, make this model of teaching applicable, relevant and necessary in the different educational levels.S

Los métodos de trabajo educativo, su expresión en la formación de los recursos humanos de la carrera de enfermería

Evaluación de factores de riesgo en accidentes oculares graves infantiles / Assessment of the risk factors for severe ocular accidents in children

Objetivo: evaluar factores de riesgo en accidentes oculares graves infantiles. Métodos: se realizó una investigación aplicada, epidemiológica, descriptiva, longitudinal y prospectiva sobre accidentes oculares graves en el Servicio de Oftalmología del Hospital Pediátrico Provincial de Pinar del Río (2006-2007). El universo y muestra estuvo constituido por dos grupos de niños de 1- 20 años, ambos sexos y todas las etnias. Primer Grupo: Niños con accidente ocular grave, Segundo Grupo: Niños sin accidente ocular; determinándose una muestra total de 130 seleccionados mediante muestreo aleatorio simple. Fueron utilizados métodos empíricos y teóricos de investigación científica. Resultados: el trauma ocular representó el 87,8% de los ingresos de urgencia durante el período. Se encontró que el grupo etáreo de 9-12 años (40%), y sexo masculino (89,2%) fueron los más afectados. Un 76,9% de los accidentados residía en zona rural.

Rendimiento de Habilla Negra (Paseolus Vulgaris L.) Influenciado por la Aplicación de Fertilizantes Quimicos

The research work had as a general objective, to determine the most efficient applications of chemical fertilizers in terms of development and performance of the broad bean crop. The objective of the experiment was to evaluate the response of the bean to the addition of Macro and microelements in different stages of application. It was conducted in the Experimental Field of the Faculty of Agricultural Sciences of the National University of Asunción, Branch Pedro Juan Caballero, Republic of Paraguay; The experimental design used was completely randomized blocks (DBCA) with four treatments and four repetitions. The treatments consisted of the application of chemical fertilizers, T1: CONTROL, T2: microelements; T3 NPK T4: NPK plus Microelements. The variables evaluated were number of pods per plant, number of grains in each pod, weight of 100 grains, yield kg/ha. The application of NPK plus microelements showed better results in the number of pods per plant and number of grains per pod respectively, as well as numerically they presented superior results for yield per hectare.El trabajo de investigación tuvo como objetivo general, determinar las aplicaciones más eficientes de fertilizantes químicos en cuanto a desarrollo y rendimiento del cultivo de habilla.
