Use Of Biopolymer Entrapped Sulfate Reducing Bacteria And Metal Nanoparticles For Effective Aqueous Sulfate Removal, Seydou Cisse Jan 2013

Use Of Biopolymer Entrapped Sulfate Reducing Bacteria And Metal Nanoparticles For Effective Aqueous Sulfate Removal, Seydou Cisse

Environmental and Conservation Sciences

Sulfate reducing bacteria (SRB) isolated from activated sludge were used to investigate sulfate removal from aqueous solution using calcium alginate entrapped SRB in batch studies with ethanol and lactose as the carbon sources. The interferences of pH, temperature, Al3+, Cu2+, and Zn2+ on sulfate removal were also investigated. Further, sulfate removal experiments were conducted with co-entrapped SRB and nanoscale zero-valent iron (NZVI) and separately entrapped SRB and NZVI. Results indicate that EntSRB can effectively remove sulfate from aqueous solution. 88-95% sulfate removal was achieved. Both ethanol and lactose worked well as carbon sources for entrapped bacteria.

A Robust Sound Perception Model Suitable For Neuromorphic Implementation., Martin Coath, Sadique Sheik, Elisabetta Chicca, Giacomo Indiveri, Susan L. Denham, Thomas Wennekers

School of Engineering, Computing and Mathematics

We have recently demonstrated the emergence of dynamic feature sensitivity through exposure to formative stimuli in a real-time neuromorphic system implementing a hybrid analog/digital network of spiking neurons. This network, inspired by models of auditory processing in mammals, includes several mutually connected layers with distance-dependent transmission delays and learning in the form of spike timing dependent plasticity, which effects stimulus-driven changes in the network connectivity. Here we present results that demonstrate that the network is robust to a range of variations in the stimulus pattern, such as are found in naturalistic stimuli and neural responses. This robustness is a property …

Pharmacy Faculty Articles and Research

A number of cyclic peptides including [FR](4), [FK](4), [WK](5), [CR](4), [AK](4), and [WR](n) (n = 3-5) containing L-amino acids were produced using solid-phase peptide synthesis. We hypothesized that an optimal balance of hydrophobicity and charge could generate self-assembled nanostructures in aqueous solution by intramolecular and/or intermolecular interactions. Among all the designed peptides, [WR](n) (n = 3-5) generated self-assembled vesicle-like nanostructures at room temperature as shown by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and/or dynamic light scattering (DLS). This class of peptides represents the first report of surfactant-like cyclic peptides that self-assemble into nanostructures. A plausible mechanistic insight into …

Synthesis, Photophysics, And Nonlinear Absorption Of Platinum (Ii) And Iridium (Iii) Complexes, Zhongjing Li

Chemistry and Biochemistry

Square planar d8 platinum(II) complexes and octahedral d6 iridium(III) complexes were synthesized. Their photophysics were studied in detail. Structure-property relationship was studied by varying the substitution on the ligands or the π-conjugation extent of the ligands. In Chapter 2, bipyridyl platinum(II) bisstilbenylacetylide complexes (2-1 – 2-6) with different auxiliary substituents on the stilbenylacetylide ligands were synthesized. While the substitution of H on the 4'-position of stilbene by Br and OMe groups does not alter the photophysical properties of the complexes eminently, the photophysical properties are significantly tuned by the CHO, NO2 and NPh2 substituents. In Chapter 3, platinum(II) complexes (3-1 …

Multiscale Modeling Of Electromagnetic Radiation Transport, Erik David Sapper Jan 2013

Multiscale Modeling Of Electromagnetic Radiation Transport, Erik David Sapper

Coatings and Polymeric Materials

The transport of electromagnetic radiation is a critical factor in determining many of the advanced features of novel materials, composites, and coatings systems. The radiation interaction with a material's surface, as well as its transport and interaction within the material, both combine to produce the overall electromagnetic signature of that object, which is the root cause of the color and appearance of these materials. Historically, approaches to light scattering behavior prediction focus on either the surface interactions or the bulk interactions, and the models most used today are valid only for certain compatible size and length scales of radiation.

Towards Providing Test Case Meta-Data To Assist Dynamic Regression Test Scheduling, Arti Katiyar Jan 2013

Towards Providing Test Case Meta-Data To Assist Dynamic Regression Test Scheduling, Arti Katiyar

Computer Science

Autonomic software is typically characterized by dynamic adaptation, a self-management process in which the system adds, removes, and replaces its own components at runtime. At the end of maintenance, the modified software would be retested to: (1) validate added or updated software features, and (2) ensure that new errors were not introduced into previously tested components, i.e., regression testing. King et al [14] introduced an implicit self-test characteristic into autonomic software. His approach modifies the success of a runtime testing approach for autonomic software depends on the way tests are selected and scheduled for execution, which still remains an open …
