A research work was carried out with veterinary medicine students from two universities in Lima, Peru, to determine factors that influence academic performance and the relationship between family functioning and academic performance. For this, 392 students were randomly surveyed (173 from the Universidad Nacional Mayor de San Marcos and 219 from the Universidad Científica del Sur). For data collection, a 20-question survey was applied based on the Family Cohesion and Adaptability Assessment Scale (FACES III). The results showed that the final average grades of the courses of the total population of students ranged from 12.9 to 13.2, with passing grades in both universities. Academic performance did not have a significant relationship with family types according to Olson's Circumflex Model; however, it was possible to establish significant differences in the final averages of the grades ...

The present study aimed to evaluate the effect of treating broiler litter with active aluminosilicate on productive parameters of broiler chickens. Four hundred broilers Ross 308 of both sexes were reared for 44 days. Half of them were reared on litter treated with aluminosilicate and the other half on untreated litter. Productive performance of chicks and ammonia concentrations, atmospheric ph, litter ph, and moisture ratio of the litter were evaluated on a weekly basis. Additionally, lesions in breast and foot pads were also evaluated. Body weight gain, feed conversion index, and productive efficiency index were statistically similar between the two groups. No breast lesions were observed and the degree of lesions in foot pads was similar in the two groups. The ammonia concentrations, atmospheric ph, and litter ph were higher in the non-treated litter group showing that the litter trea...

El estudio evaluó el efecto del tratamiento de la cama con un aluminosilicato activado sobre los parámetros productivos en pollos de carne. Se utilizaron 400 pollos de carne de ambos sexos de la línea Ross 308. La mitad se crió sobre cama tratada con aluminosilicato y la otra mitad sobre cama no tratada hasta los 44 días de edad. Se analizó los datos productivos de las aves, niveles de amoniaco y pH atmosférico del gallinero, y pH y porcentaje de humedad de la cama. También se evaluó la presencia de pododermatitis y lesiones a nivel de la pechuga. La ganancia de peso, el índice de conversión alimenticia y el índice de eficiencia productivo europeo fueron estadísticamente similares entre los dos grupos. No se evidenció lesiones a nivel de la pechuga y el grado de lesiones a nivel de las patas fue similar en ambos grupos. El nivel de amoniaco, pH atmosférico y pH de la cama ...

El agua es un fluido de proceso de mucha importancia en Tecnología Nuclear. La Unidad de Actividad Química (UAQ) ha dedicado mucho esfuerzo al estudio de sus propiedades fundamentales y de sus aplicaciones, con miras a optimizar el funcionamiento de los sistemas refrigerante, moderador y auxiliares en Centrales Nucleares. Uno de los aspectos fundamentales de estudio ha sido la necesidad de mantener agua muy pura en esos circuitos, para minimizar la corrosión de los materiales estructurales, y la incorporación de radionucleídos al agua. Esta incorporación es responsable de un incremento de las dosis ocupacionales de radiación de los trabajadores. La tecnología del agua como insumo de la industria nuclear requiere poseer capacidades en la producción y mantenimiento de agua extremadamente limpia. Dichas capacidades son las que se usan también para brindar soluciones a la provisió...

Water is a fluid process of great importance in Nuclear Technology. Chemical Activity Unit (UAQ) has devoted much effort to the study of fundamental properties and applications in order to optimize the operation of cooling systems, and auxiliary moderator in nuclear power plants. One of the fundamental aspects of this study was the need for very pure water in these circuits, to minimize corrosion of structural materials, and the incorporation of radionuclides into the water. This incorporation is responsible for increased radiation dose occupational workers. Water technology as an input of the nuclear industry, for skills, is required in the production and maintenance of water extremely clean. These capabilities are also used to provide solutions to the water supply to isolated rural communities, and small businesses to find alternatives to treat their effluents. Studies for this purpose...
