in the construction process of a plastic concrete cut-off wall, concreting is usually performed using the termie pipe method. in this method, concreting is performed from the lowest point in the excavated trench (containing the slurry) using a funnel and the pipe connected to it. the concrete poured in the funnel gradually settles in the panel through the termie pipe which is beneath the slurry...

Rice Husk Ash (RHA) is natural Pozzolan containing reactive silica and/or aluminum. When the material is mixed with lime in powdered form and in the presence of water, it will set and harden like cement. This work uses Osadebe’s optimization model to optimize the shear modulus of concrete made from RHA. The strengths predicted by the model are in good agreement with their corresponding experime...

concrete is one of the most important construction materials widely using in hydraulic structures, such as lining of irrigation canals. concrete durability might be decreased due to the environmental or inner factors with physical, chemical or mechanical reactions. since, the climatologically condition is variable in most part of the country, local studies are needed to evaluate of the weakness...

What I intend to demonstrate in this paper is that Heidegger pretends immunize his philosophy from any possibility of refutation. The thesis argue precisely because the ontological cannot be corroborated by empirical realm and, on other hand, does not provide a foundation for what he considers priori, German philosopher shields kind reply: beings at same time, it can only reached “leap” (Sprung...

The Artificial Grammar Learning (AGL) paradigm provides a means to study the nature of syntactic processing and implicit sequence learning. With mere exposure and without performance feedback, human beings implicitly acquire knowledge about the structural regularities implemented by complex rule systems. We investigate to which extent a generic cortical microcircuit model can support formally e...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...
