In the present work, the nutritional evaluation and control of the diet of the children studying in gardens assisted by Qali Warma, Alto Trujillo 2018 was carried out. The nutritional evaluation was carried out by anthropometric methods, according to the WHO reference tables. To control the diet, the 24-hour reminder method was used. According to the BMI, it was found that 73% of the children of the I.E N ° 2193 present a normal nutritional status; 7% overweight, 7% severe thinness and 13% thinness risk. In the Darío Celis Vásquez institution it was found that children have 86% of obesity, 7% of children have a normal nutritional status and 7% are overweight. According to the indicator (T / E), 100% of the children who attend the Darío Celis Vásquez garden have a normal nutritional status, and those who attend the Educational Institution No. 2193, 93% have a normal nutritional statu...

The purpose of this study was to determine the effect of temperature on the reaction rate of 1-fenilbutan-1-ona and ethylene glycol in the synthesis of 2-phenyl-2-propyl-1.3-dioxolano. The study was performed by determining the chemical kinetics of reaction speed at different temperatures 50 °c and 70 °c. According to this method, we submit to the reactants in an acidic medium with a light organic solvent (benzene). then the distillation equipment was installed a reflux with light solvent separator at a temperature of 50 and 70 °c; until a constant volume of water is obtained from the chemical reaction; getting the product. the following results were obtained: percentage of practical performance of the cetal (2-phenyl-2-propyl-1.3-dioxolano) is 60% and 64% respectively, boiling point was 228 ° c, density at 22 °c was 1,057; refractive index 1,623; the activation energy of 5,321 kcal...
