Influence of Mechanical Properties of Concrete and Soil on Solicitations of Mat Foundation

This work studies the influence of mechanical and geometrical characteristics of the concrete and the soil on the stresses in a mat foundation. In this study, the soil-structure interaction is modeled by two parameters, the modulus of subgrade vertical reaction (k) and the modulus of subgrade horizontal reaction (2T). These two parameters are dependent on the geometrical and mechanical characteristics of the system. Results of this study show a sensitivity of solicitations to variations of geometrical and mechanical characteristics of the model. Although solicitations in the plate are sensitive to mechanical properties of concrete, these solicitations are strongly influenced by the mechanical and geometrical characteristics of the soil mass. However, it should be noted that the influence of Eb is denoted in the center of the plate whereas the Es feels almost in the same manner over the entire extent of the plate. This study also shows that for the same load cases, the values of the torsion moment and shear stress are not significant those of bending moments and normal stresses, respectively.

Cortical reaction and solicitation mechanism in Hemibarbus labeo ovum

There are 1 to 4 rows and five types of cortical alveoli in the cortex of the pallas(Hemibarbus labeo)egg.From the outer to the inner of the cortex,the diameter of the cortical alveoli decreases gradually.We found a new structure named solicitation speckle at the low latitude of the animal pole and near the micropylar apparatus between the ovum envelope and cell membrane in the zygote of fish.The solicitation speckle similar to type I cortical alveoli was very purple in H.E chromosome,and it had no obvious boundary with the ovum envelope and membrane.Moreover,no membrane around the solicitation speckle in TEM was found.In SEM,the solicitation speckle looked flocculent.During cortical reaction,the solicitation speckle played a very important function in arousing cortical reaction.Thirty-five seconds after fertilization,cortical alveoli began to break down near the low latitude of the animal pole.At the same time,the same thing happened near the micropylar apparatus before cortical reaction.Both starting points encountered and healed up at the vestibule of the micropylar apparatus.The cortical reaction that happened near the low latitude of the animal pole was another new pattern.The cortical reaction was divided into four parts that included latent period,developmental period,climactic period and declining period.In the latent period,no cortical alveoli were released.In the developmental period,a few cortical alveoli were released outside the cortex.In the climactic period,several cortical alveoli were inosculated into a big vesicle and released intensely.In the declining period,the type V cortical alveoli and the other remnant cortical alveoli were released.Five minutes after fertilization,cortical alveoli were released entirely in the animal pole.Five minutes after fertilization,all of the remnant cortical alveoli were released.This leads us to conclude that cortical reaction is induced by type I cortical alveoli,and the solicitation speckle is a volcanic chain reaction under water or the other lower osmotic pressure of fluids.The outer cortical reaction can accelerate the inner cortical reaction.While cortical alveoli releases in batches,the cell plasma membrane is reorganized over and over.No cortical alveoli were found below the micropylar tube where sperm enters the ovum,which suggests that the cortical reaction prevents polyspermy.
