RISFracture Toughness of HSLA Coiled Tubing Used in Oil Wells Operations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Coiled Tubings are thin walled steel tubes of 25–89 mm diameter and thousands meters long, used in the oil industry for production and maintenance services. They suffer plastic deformation ...
Analytical and Experimental Lateral Load Behavior of Unbonded Posttensioned Precast Concrete Walls
Publisher: American Society of Civil Engineers
Abstract: The use of unbonded posttensioned (UPT) precast concrete walls with horizontal joints as the primary lateral load resisting system in seismic zones has been considered in several previous studies. This paper introduces a ...
Optimization of Reactor Depth in Membrane Bioreactors for Municipal Wastewater Treatment
Publisher: American Society of Civil Engineers
Abstract: Aeration energy demand represents 45 to 80% of the total energy consumption of a wastewater treatment plant (WWTP). In membrane bioreactor (MBR) technology, biological aeration requirements are higher than in conventional ...
The Effect of Modifying TiO2 on Catechol and Resorcinol Photocatalytic Degradation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The photocatalytic features of TiO2 doped with ferric oxides or mixed with activated carbon (AC-TiO2) are compared with those of the unmodified Degussa P-25 TiO2. These new catalysts show ...
Comparative Study of Photocatalytic Degradation Mechanisms of Pyrimethanil, Triadimenol, and Resorcinol
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The photocatalytic degradation of an endocrine disruptor (resorcinol) and of two fungicides (pyrimethanil and triadimenol) has been studied and compared. The effect of pH, oxygen, and H2O2 on ...
Cast-In Hypereutectic Aluminum Liners for Engine-Blocks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A series of experimental trials was carried out to study the metallic bond produced when hypereutectic aluminum liners are cast-in hypoeutectic aluminum engine-blocks. The samples were cast in ...
Column Base Connections for Hollow Steel Sections: Seismic Performance and Strength Models
Publisher: American Society of Civil Engineers
Abstract: The seismic response of exposed hollow steel section columns to base plate connections is examined through a series of eight experiments. The prototype-scale tests investigate a range of variables including base plate size ...
Application of a New System of Self-Tensioning to the Design of Large-Span Wood Floor Framings
Publisher: American Society of Civil Engineers
Abstract: This study describes a self-tensioning system in which the gravitational loads acting on a horizontal structural element are automatically converted to a posttensioning force on that component. The self-tensioning effect ...

Comparative Study of Phenolics Degradation Between Biological and Photocatalytic Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Phenol and phenol compounds are toxic organics that can be found in many industrial wastewaters. Biological wastewater treatments are considered to be the most convenient methods owing to their ...
