This study presents wave height distribution in terms of stem wave evolution phenomena on partially perforated wall structures through three-dimensional laboratory experiments. The plain and partially perforated walls were tested to understand their effects on the stem wave evolution under the monochromatic and random wave cases with the various wave conditions, incident angle (from 10 to 40 de...

A numerical study is performed to investigate the effect of height-to-width aspect ratio, Grashof number, and Schmidt number on the Double-diffusive convection of a fluid contained in a rectangular cavity with partially thermally active side walls. The active part of the left side wall is at a higher temperature and concentration than that of the right side wall. The length of the thermally act...

Active matter concerns the self-organization of energy consuming elements such as motile bacteria or self-propelled colloids. A canonical example is an active Brownian particle (ABP) that moves at a constant speed while its direction motion undergoes rotational diffusion. When ABPs are confined within channel, they tend to accumulate channel walls, even when inter-particle interactions ignored....

Hybrid steel and concrete seismic-resistant systems made by frames with reinforced infill walls (SRCWs) have potential advantages over structural solutions only or (RC). In fact, the high initial stiffness of is useful to minimize damage non-structural elements under frequent (low moderate) earthquakes while ductility dissipative capacity allow good performances rare (high-intensity) events. Eu...

The synthesis and accumulation of proteinase inhibitor I in excised tomato leaves can be induced with oligosaccharides obtained by fungal endo-alpha-1,4-polygalacturonase digestion of a pectic polysaccharide (M(r) 5000-10,000) isolated from tomato leaves. Active oligosaccharides were also released from isolated tomato leaf cell walls by endopolygalacturonases partially purified from tomato plan...

calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. the upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. in this paper formulation of finite element limit analysis is introduced ...

The design of a Geosynthetic Reinforced Soil (GRS) wall for internal stability requires computing the reinforcement embedment length against pullout failure. The location of failure plane is important input for this design. The current FHWA design guidelines assume the location of failure plane based on Rankine theory. While this assumption holds true for conventional walls it is unconservative...

background and aims. because of compromised angulations of implants, the abutments are sometimes prepared. the purpose of this study was to investigate the effect of removing one wall of the implant abutment on the retention of cement-retained crowns. materials and methods. four prefabricated abutments were attached to analogues and embedded in acrylic resin blocks. the first abutment was left ...
