Behavior of clayey soil existing in the portoviejo canton and its neutralization characteristics
Get PDFoai:ojs.pkp.sfu.ca:article/4An investigation has been carried out on soil characterization and behavior in the canton of Portoviejo province of Manabí, in the Eloy Alfaro street sector of the Andrés de Vera Parish; where pits or open-air surveys were carried out and experimental laboratory tests of soils. It was demonstrated that soils have expansive properties of different characteristics, from medium to high degree of expansively according to the results of Laboratory of Soil Mechanics, where samples were tested analyzing the behavior according to the soil type. In this context, the results obtained by incorporating lime into the mixture are presented in 3 and 6%, thus obtaining a reduction by contraction to the volumetric change of the soil between 8 and 13%, allowing to improve its physical and mechanical properties; as well as its increase to bearing capacity by the California Bearing Ratio (CBR) test method from 9 to 16%, thus improving soil plasticity. With the results obtained, a description of the soil could be elaborated to determine the variations and changes according to the lime content, which was added to the soil, which allowed to reduce the deformations and damages caused to the superficial and structural pavement caused by the clays expansive, because in contact with the water the soil expands and at the same time when it drains the water contracts, proving that stabilizing the expansive clays with hydrated lime would improve the conditions of the pavement and its useful life
The effect of aerobic and anaerobic physical training on the absorptive cells, absorption of carbohydrate and protein in small intestine
Get PDFThe purpose of this study is to investigate the morphofunctional response of a total number of absorptive cells, and carbohydrate and protein absorption capability in the small intestine of Rattus norvegicus strain Wistar (RNSW) that has been subjected to aerobic and anaerobic physical training based on the morphofunctional physiological paradigm. This study was based on the separate sample pretest-posttest control group design, using a t-test, and multivariate SPSS ten program, with five percent level of significance. The sample consisted of one hundred and twenty, male RNSW, with average age of five months, and body weight of 246-278 grams. They were divided into twelve groups at random, i.e. four pretest groups, two control groups, and six treated groups where different diets were given thirty minutes before undergoing posttest. The experimental animals underwent four weeks physical training (twelve times), three groups were given aerobic physical training by swimming with a burden of three percent fasting body weight, the others three groups received anaerobic physical training by swimming with a burden of nine percent fasting body weight. The experiment was conducted at night, between 7.30 PM to 10.30 PM, in a water with a temperature of 28°C to 30°C. Result of the study revealed: (1) Aerobic and anaerobic physical training, increased the number of absorptive cells (t = -73,281, p = 0,000), and increased the absorptive capacity of carbohydrate and protein (Hotelling’s Trace = 0,244, p = 0,000). (2) There was a difference in the increased absorptive capacity of carbohydrate and protein among groups (Hotelling’s Trace = 0,404a, p = 0,000). Aerobic physical training had less influence than anaerobic physical training on the increased number of absorptive cells, and the absorptive capacity of carbohydrate and protein in the small intestine. In conclusion: (1) Aerobic physical training of swimming with a burden of three percent fasting body weight, and anaerobic physical training of swimming with a burden nine percent fasting body weight correlate with the increase the number of absorptive cells, and carbohydrate and protein absorptive capacity of the small intestine. (2) Anaerobic physical training of swimming with a burden nine percent fasting body weight has better correlation than aerobic physical training of swimming with a burden of three percent fasting body weight with the increased number of absorptive cells, and the absorptive capacity of carbohydrate and protein in the small intestine
