Directed biogenic fabrication : programming cells and their ecosystems to grow civil infrastructure
… framework for co-fabricating ecologically active civil infrastructure with living cells. I propose that imbuing our buildings and urban systems with life, or at least biologic capabilities, will enable tight interconnections between fundamental species occupying different infrastructural niches, …

An experimental study on the cyclic behaviour of riveted stiffened seat angle connection with concrete encasement.
Many older buildings have been constructed using what are considered today as semi-rigid or flexible types of connections. A concrete encasement was typically added to columns in the past for the sole purpose of fire protection. The behaviour of semi-rigid connections under cyclic loading and the …

Modeling ultrasonic transducer in homogeneous and non-homogeneous media using DPSM method
Modeling ultrasonic transducers is an important aspect of research in nondestructive evaluation and testing. In most nondestructive evaluation applications, the ultrasonic transducers are traditionally modeled as: (1) point sources generating spherical wave fronts (2) line sources generating …

Experimental and numerical study of the rod shear test for determining steel-sand interface behavior
One laboratory technique to determine the unit side resistance of piles is the rod shear test. In a rod shear test a model pile is placed inside a cylindrical soil specimen. A confining pressure is then placed around the specimen/pile assembly and the model pile axially loaded. In some cases rod …

Effect of pH on adsorption and desorption equilibria and kinetics of 2-nitrophenol and phenol onto two activated carbons.
The objective of this thesis was to investigate the impact of pH on the adsorption equilibria, adsorption kinetics, desorption equilibria and desorption kinetics. A study was conducted by using 2-nitrophenol (2NP) and phenol as organic pollutants and F-400 and WV-B carbons as adsorbents. The batch …

Seismic retrofit of existing reinforced concrete moment resisting frame structures using diagonal prestressing
… Over the years, knowledge related to structural engineering and more specifically seismic response has continued to evolve through research and field investigations. Recently, the 2005 NBCC has been made available with a new perspective on seismic design, including uniform hazard spectra provided …

Effects of the alkali-silica reaction on unloaded, statically loaded and dynamically loaded reinforced concrete beams.
The Alkali-Silica Reaction (ASR) affects many concrete structures throughout the world. Small scale, simply supported, singly reinforced concrete beams made of both reactive and non-reactive aggregate have been tested. Reactive and non-reactive concrete cylinders, resonant frequency prisms and CSA …

Metals recovery from industrial wastewaters and metallic hydroxide sludges through microbial sulphate-reduction.
This paper describes how metals originate in industrial wastewaters from the mining and metal finishing industries. Treatment of wastewaters containing dissolved metals produces a metallic hydroxide sludge which has to be disposed of in an environmentally acceptable way. It is estimated that the …

Concrete columns and beams reinforced with FRP bars and grids under monotonic and reversed cyclic loading
The use of fiber reinforced polymer (FRP) reinforcement is currently being explored by the construction industry as a new and innovative material. A significant force behind this consideration is the superior performance of FRP material in corrosive environments. FRP possesses high …

Simulation of ship-ice collision dynamics.
… It may therefore be applied more generally as an engineering tool for conceptual design and parametric analysis; either to investigate collisions with ice, or other types of obstacles, such as mud banks and reefs.

Experimental investigation of wave-induced morphological changes of gravel beaches
Gravel beaches are widespread around the North-Atlantic Ocean shorelines and can also be found along the coastlines of New Zealand, Russia and the Pacific shore of USA. Over the past decades, researchers in coastal morphodynamics have placed their emphasis on studying sand beaches but gravel …

Small and large deflection of clamped skew sandwich plates.
The problem of the small and large deflection behaviour of skew sandwich plates with built-in edges and subjected to a uniformly distributed load is investigated. Non-linear partial differential equations governing the load-displacement relationship for such plates are derived using the principle …
