The transient response of a cylindrical casing–cement structure in a poroelastic stratum under dynamic radial tractions is one of the significant issues during the analysis of downhole operations and the selection of safe material. Based on the Biot theory and general elastic mechanics, this paper gives a set of exact solutions for radial ...

With diffused aeration systems, preventing the wastewater and biomass from entering into the air distribution system is critical to ensuring continual operation of the mixing system and the elimination of solids buildup and clogging inside the pipeline. The Tideflex® Check Valve Air Diffuser is a proprietary compression molded Tideflex® unit.
Smart Dynamic Concrete (SDC) is an innovative concrete that does not require vibration for placing and compaction. It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement.

The stream from the Gusher 3hp model will reach heights of up to 50 feet, creating a full, dynamic, constantly changing pattern. The frothy, highly aerated stream is not only aesthetically pleasing, it also maintains water clarity at the same time.
Clinical Performance of Retrieved Dynamic and Static Knee Antibiotic Cement Spacers ... Significance: Dynamic antibiotic bone cement spacers have replaced their static counterparts and have shown effectiveness in curing deep infections in past studies; however, this study aims to reveal the clinical ...
Scott Aerator Pond Fountains Lack of oxygen in a body of water can lead to fish kills, foul odors, algae growth, and stagnant vegetation. Our floating aerators have been made and proven to prevent these problems by adding vital oxygen to your pond or lake, for a clean, fresh, he
How and why to use ACTIVA BioACTIVECEMENT for crown cementation ... To qualify, materials must not be passive; they must play a dynamic role in the oral environment. "Bioactive" materials are moisture tolerant, which makes them more forgiving and easier to use in the mouth. They respond to pH cycles with release and recharge of calcium and ...
Visually striking and surprisingly lightweight: Dynamic Cladding's Natural Stone Collection offers flexible design solutions for exterior facades and interior decor. In keeping with tradition, Dynamic Cladding preserves the natural texture and appearance of the stone.
A dynamic method is presented which has the following capabilities: oil temperature to 350F, oil pressure to 200 psig, oil flow rate to 2 gpm, air flow rate to 2,000 ml/min and system pressure from ground level to in. Hg (simulated 50,000 ft altitude).
The aeration characteristics of the spiral aerator were determined by conducting aeration experiments in a cement concrete tank of dimension 5 × 5 × m. Nondimensional numbers related to oxygen transfer (E) and power consumption (Ne) were proposed and expressed as functions of geometric (number of handles per shaft, n) and dynamic (Froude ...
Oct 02, 2014· Cementstabilized base course materials of 4 %, 5 %, and 6 % cement contents (by mass) were used as the study materials. The findings of this study indicate that curing durations and cement contents significantly influence the dynamic modulus values of cementstabilized base course materials.
