Considering the deficiency of proteins in the Peruvian residerifs diet, their alimentary habits and preferences in the ingesta of foods for quick consumption for the dynamism of the daily activities, one worked with the addition of proteins of high biological value in formulations of crakers. For this reason we prepare the flour, using as matter prevails to the hake that was selected applying the chart of evaluation organoléptica of Whittfogel, the procedures of obtaining of the hake flours they were compared, in those that optionally the pH was adjusted. The comparison of the elaborated fish flour was carried out with the standard flour of wheat. Tests were made with substitutions of 5, 10 and 15% of flour of having fished by wheat flour in the patron formulation of cookies and the acceptability of the product was evaluated making texture tests, color, scent and satisfaction of the pro...

In the present survey, factors influencing chocolate acceptability by kids between 6-10 years old have been identified through, the evaluation of products shape, color and savor. It was determined that the child population showed their preference for a milk covering and an oval shape in chocolates.

In the present study a Risk Control Program for exposures to electric power in a bank is approached, showing the main guidelines contributing to diminish electric accidents in a bank, and thus lessen short-circuits consequences, such as fires and losses of information.

Footwear imports have been increasing in recent years and have radically affected the profitability of the footwear sector, especially those from China. This situation has particularly affected SMEs in this sector, as they lack sophistication with respect to the quality of their products and the lack of quality assurance strategies. In Peru, SMEs represent a great importance for its economy, since approximately 99.5% of its companies are SMEs. Specifically, SMEs in the footwear sector generate 57,000 direct jobs and contribute 1.2% of the industrial GDP. Therefore, there is a need for research to ensure the quality of the footwear produced by SMEs in order to make them more competitive in the market. This through a model of quality assurance by combining the tools of quality standardization and motivation ERC. This is expected to reduce the rate of defective production of SMEs in the foo...

Nanoparticles (NPs) are currently the subject of intense scientific research due to a wide variety of potential applications in various fields such as medicine, optics, electronics, nano‐chemistry and agriculture. The properties of these nanostructures depend on their size and shape, and specific properties can be obtained by varying these characteristics. For this reason, a bibliographical analysis was carried out covering different investigators who studied the various methods of synthesis of copper (NPsCu) and silver (NPsAg) nanoparticles, as well as the factors that modify the shape and size of these particles. A main conclusion of this study is that the shape and size of the nanoparticles depend upon factors that can be controlled.

Actualmente las nanopartículas (NPs) son un área de intensa investigación científica, debido a una amplia variedad de aplicaciones potenciales en campos tales como biomédicos, ópticos, electrónicos, nano química o agricultura. Las propiedades de estas nanoestructuras están en función de su tamaño y forma, obteniendo propiedades específicas de acuerdo a la variedad de dichas características mencionadas. Por ello se realiza un análisis bibliográfico de diferentes investigadores que realizaron un estudio riguroso acerca de los diferentes métodos de síntesis de nanopartículas de cobre (NPsCu) y nanopartículas plata (NPsAg), así como también los factores que modifican la forma y tamaño de partícula. Como conclusión principal podemos señalar que el control de la forma y tamaño de las nanopartículas se debe a factores que puedan ser controlables.

El objetivo del trabajo fue evaluar el efecto de la inulina como prebiótico natural sobre los parámetros productivos de cuyes en crecimiento. Se realizó en el galpón de cuyes de la EP de Ingeniería Agroindustrial de la UNMSM con sede en San Juan de Lurigancho – Lima. Se emplearon 5 tratamientos: T1: Control (con APC), T2: Sin inulina y sin APC, T3: 150 ppm de inulina, T4: 300 ppm de inulina y T5: 600 ppm de inulina; en un periodo de 5 semanas. Se emplearon 40 cuyes machos genotipo Cieneguilla, de 28 +/- 2 días de edad, adquiridos de una granja de cuyes de Manchay. Se empleó un Diseño Completamente al Azar. Los animales fueron distribuidos en 5 tratamientos y 4 repeticiones, cada repetición representada por 2 cuyes alojados en una poza, previamente identificados. Los cuyes que recibieron el tratamiento con 150 ppm de inulina presentaron el mayor consumo de alimento con 1154 g, ...

The study was conducted at the Alpaicayan Experimental Centre, Daniel Alcides Carrión National University, Pasco, Peru, with the objective of determining the forage production and nutritional quality of oats associated with vetch. Forage production was determined in green matter content (GM), dry matter (DM) and percent of dry matter (%DM). For the nutritional value, crude protein (%CP), neutral detergent fibre (%NDF), acid detergent fibre (%ADF), calcium (%Ca) and phosphorus (%P) were determined. The treatments were T-1 (Creole oat, 150 kg/ha), T-2 (Mantaro 15 oat, 110 kg/ha), T-3 (Mantaro 15 oat plus vetch, 110 and 30 kg/ha) and T-4 (creole oat plus vetch, 150 and 30 kg/ha). GM production indicated that T-1 and T-4 were similar but significantly greater than T-2 and T-3 (p<0.05); however, without significant differences in DM production between treatments. T-4 obtained the largest ...

El estudio se realizó en el centro experimental de Casaracra, a una altitud de 3 819 msnm, perteneciente a la Universidad Nacional Daniel Alcides Carrión. Se utilizaron tres tratamientos: alfalfa WL 350 (T1), alfalfa W 440 (T2) y alfalfa Brown 6 (T3). La producción forrajera se determinó en materia verde (MV), materia seca (MS) y el porcentaje de contenido de materia seca. En la calidad nutricional se analizaron cinco variables: proteína total, fibra detergente neutra, fibra detergente ácida, calcio y fósforo. Los datos obtenidos fueron analizados utilizando el diseño completamente al azar, así como la prueba de Tukey de significancia (p<0.05). Los resultados de producción forrajera en MV y MS no mostraron diferencias significativas (p<0.05) entre los tratamientos T2 y T3, así como en el porcentaje de materia seca entre los tratamientos T1 y T3. En la calidad nutricional, las ...

In this work the synthesis of magnetite nanoparticles by coprecipitación in inverse microemulsion, which were introduced inside the pores of the polystyrene nanoparticles is reported. The nanoparticles of porous polystyrene were synthesized by heterogeneous polymerization in semicontinuo, which were employed like cover polymeric due to their biocompatibility and biostability. Through the analysis by X-ray diffraction was verified the structure of the magnetite, and estimated its average diameter of 9 nm. The polystyrene nanoparticles loaded with magnetite were prepared in different compositions magnetite/polymer and were determined by the test of magnetization that the magnetic moment (emu/g) is increased when the content of magnetite in the porous of polystyrene nanoparticles is increased.
