Richardson and Zaki (1954) formulated a correction function for determining the sedimentation velocity of a suspension of particles on the basis of the velocity of a single particle not subject to forces other particles in the suspension. The Reynolds number for the flow is less than 0.25, so the Stokes equation can be used to calculate their velocity. The exponent in the Richardson and Zaki correction function is n = 4.65, independent of size. This paper describes research with micro particles in which the value of the exponent of the Richardson and Zaki correction function was found to be inversely dependent on the size of the micro particles.

The aim of the present work was to optimize the sensorial and technological features of ice cream. The experimental work was performed in two stages: 1) optimization of lactose enzymatic hydrolysis, and 2) optimization of the process and product. For the first stage a complete factorial design was developed, optimized using both response surface and the steepest ascent method. In the second stage a mixture design was performed, combining the process variables. The product with the best sensorial acceptance, high yield and low cost was selected. The acceptance of the product was developed by an untrained taster’s panel. As a main result the sensorial and technological features of the final product were improved, establishing the optimum parameters for its elaboration.

La función de corrección formulada por Richardson y Zaki en 1954, se utiliza para determinar la velocidad de sedimentación de un colectivo de partículas a partir de la velocidad de una partícula que no se encuentra sujeta a la acción de las fuerzas de otras partículas en la suspensión. Dado el tamaño de las partículas que es micrométrico y el valor del número de Reynolds del escurriento que es menor a 0,25; se emplea la solución de Stokes para evaluar la velocidad de éstas, por lo que el valor del exponente de la función de corrección de Richardson y Zaki es n = 4,65; independientemente del tamaño. El presente trabajo demuestra a partir de un trabajo experimental con micro partículas que el valor del exponente de la función de corrección de Richardson y Zaki depende de su tamaño y es mayor mientras menor es el diametro de éstas.

Introduction and objectives: The objective of this study is to determine if the type of cleft lip and palate is associated with a higher risk of alteration of the Eustachian tube. Materials and methods: A descriptive case series study was carried out with an inferential analysis of children operated on for cleft lip and palate at the San Bartolomé hospital during the years 2018 and 2019. Results: 48 patients with tympanometry were evaluated, 62.5% male (n = 30) and 37.5% female (n = 18), the mean age was 1.3 years. The type of cleft lip and palate was determined using the Veau classification, the most frequent type found was Veau type III: 62.5% (n = 30), the least frequent type was Veau I with 4.2% (n = 2). The evaluation of the function of the Eustachian tube was performed with tympanometry, defining the type B curve as pathological. In the studygroup, there was an overall prevalence ...

The aim of the article is to study the sustainable practice and the economic role of the agricultural biodiversity in the more unstable environments of the floodplains, the "sand bars" and "silt bars". The study was carried out in seven communities of the "Setor Muyuy" near the town of Iquitos in 2004. This study also compares the agrobiodiversity of a community in 1999. The methodology used is the same applied by the "People, Land Management and Environmental Change" from United Nations University, which prioritizes experimentation, demonstration and explication of the agricultural systems by farmers themselves. The results show the agricultural systems of sand bars and silt bars vary according to the type of annual sediment. In 2004, agricultural credit is promoted for rice. The agricultural biodiversity in sand bars and silt bars comprised 9 cultures in 1999 and 2 cultures in 2004. Th...

Left lung autotransplantation was practiced in twenty dogs, divides in two groups of ten each one, in the first group the autotransplantation was performed following conventional technics with no conservation of the peribronchial structures, menwhile in the second group the bronchial artiries had been preserved. All of them had bronchoscopy, bronchoespirometry pulmonary X rays and bronchography in the inmediate pre and post operative, in first, second and third months; finally the dogs that survive more than 90 days, were sacrifaiced and necropsied as the ones which died before reaching this period. The surgical technique and the methods for bronchoscopy, bronchoespirometry, radiology and broncography are described. Eleven of twenty animals reached to the final part of the experiment, 4 from the first group and 7 from the second group. High mortality was observed in the first group on th...

Se realizó un experimento para evaluar los efectos del descanso al pastoreo sobre la estructura de la vegetación, la función hidrológica y el estatus ecológico en pastizales de condición regular para vacunos. El área de estudio está ubicada a 4 095 msnm, en la comunidad campesina Cordillera Blanca, Región Ancash, Perú. El diseño experimental fue factorial 2 x 2 en bloques, donde los factores fueron: a) dos sistemas de pastoreo P1: Pastoreo no controlado en tierras de usufructo comunal y P2: Descanso o exclusión total de pastoreo, y b) tres años de monitoreo comprendidos entre el 2011 al 2013. Al finalizar el estudio, la estructura de la vegetación fue cambiando según el régimen de uso del pastizal, en donde el descanso favoreció al aumento de especies de gramíneas nativas y en detrimento de las hierbas, pseudogramíneas y arbustos. El descanso incrementó la cobertura v...

Objectives: To determine the relationship between the level of resilience and family functionality in adolescents of the Ventanilla shelter, Peru. Material and Methods: The study approach is quantitative, the design is non-experimental, correlational and cross-sectional. The population consisted of 160 adolescents residing in the shelter. The instruments used were the Connor-Davidson resilience scale (CD-RISC) and the family APGAR questionnaire. Results: In relation to the level of resilience, the average level predominated (52.5%), followed by the high level (46.9%) and low level (0.6%). The dimension of resilience that presented the highest percentage of high level of resilience was control and purpose (61.9%), the one that presented the highest percentage of low level of resilience was spirituality (8.1%). Regarding family functionality, families with mild dysfunction predominated (33...
