A Comparison Study on the Effect of Various Layered Sandy Soil Deposited on Final Settlement under Dynamic Loading

The foundation is expansion in base of column, wall or other structure in order to transmit the loads from the structure to under footing with a suitable pressure with soil property. There are two conditions to design foundation: 1. The stress is applied by footing on soil is not exceeded allowable bearing capacity ( ). 2. The foundation settlement and differential settlement are due to applied loads are not exceeding the allowable settlement that based on the type and size of structure, the nature of soil. Rigid square machine footing with dimension 200*200 mm with two types of relative density (50 and 85)% medium and dense density respectively are using in this study in different 28 models to show the effect of layered sandy soil in two configuration, medium-dense MD and dense-medium DM on the final settlement in magnitudes and behaviors under dynamics loads applying with different amplitude of loads (0.25 and 2) tons at surface with amplitude-frequency 0.5 Hz with explain the effect of reinforcements material on reduction the magnitude of settlement. The final results appeared with respect to the specified continuous pressure and the number of loading cycles, the resulting settlement from the dynamic loading increases with the increase in the dynamic pressure magnitude, the variation on densities of layered soil effect on the amount of settlement due to different loads applied...

Behavioural seasonality of the estuarine dolphin, Sotalia guianensis, on the north-eastern Brazilian coast

This study tested the association between variation in precipitation and behavioural seasonality in Sotalia guianensis , at the Curral inlet (6o13′00″S 35o3′00″W) in north-eastern Brazilian coast. From October 1999 to September 2003, observations were carried out four days a month. Behaviours were registered instantaneously each five minute interval. The observation period consisted of six hours into the daytime (0600 to 1700 h). Two observers inspected the area simultaneously, from a fixed location at the top of the cliff. During June to November, socialization (Md JN = 1.524; Md DM = 0.667; U = –2.848; P = 0.004) and forage (Md JN = 3.268; Md DM = 1.762; U = –2.881; P = 0.004) were significantly higher than from December to May, although the number of individuals (Md JN = 6.000; Md DM = 5.000; U = –1.395; P = 0.163) did not change over the year. Such behavioural seasonality was not associated with dry/rainy periods (number of individuals: Md RS = 5.000; Md DS = 6.250; U = –1.672; P = 0.095; socialization: Md DS = 0.947; Md RS = 1.464; U = –0.858; P = 0.391; and forage: Md DS = 3.017; Md RS = 2.292; U = –1.506; P = 0.132). These results support behavioural seasonality in an equatorial odontocete population.
