Apparatus And Method For Low Flux Photocatalytic Pollution Control (Div), Ali Raissi, Eric Martin, Nazim Muradov

UCF Patents

A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to both low and high-flux photoreactor design and scale-up. The low-flux method is based on the implementation of natural biopolymeric and other low-pressure drop media support for titanium dioxide and other band-gap photocatalysts. The high-flux method is based on the implementation of multifunctional metal oxide aerogels and other media in conjunction with a novel rotating fluidized particle bed reactor.

On The Design And Performance Of Cognitive Packets Over Wired Networks And Mobile Ad Hoc Networks, Marino Ricardo Lent

Retrospective Theses and Dissertations

This dissertation studied cognitive packet networks (CPN) which build networked learning systems that support adaptive, quality of service-driven routing of packets in wired networks and in wireless, mobile ad hoc networks.

The first part of this study completed the design of the CPN algorithm for wired systems by revisiting the decision making procedure employed by smart packets in the former initiative. To conduct evaluation studies, this work proposed two implementation architectures, both of which were integrated into the Linus 2.4 kernel.

The second part of this dissertation extended CPN to ad hoc networks by introducing mechanisms to handle node mobility …

Lim Kinase 1 Is Essential For The Invasive Growth Of Prostate Epithelial Cells - Implications In Prostate Cancer, Monica Davila, Andra R. Frost, William E. Grizzle, Ratna Chakrabarti

Faculty Bibliography 2000s

Mammalian LIM kinase 1 (LIMK1) is involved in reorganization of actin cytoskeleton through inactivating phosphorylation of the ADF family protein cofilin, which depolymerizes actin filaments. Maintenance of the actin dynamics in an ordered fashion is essential for stabilization of cell shape or promotion of cell motility depending on the cell type. These are the two key phenomena that may become altered during acquisition of the metastatic phenotype by cancer cells. Here we show that LIMK1 is overexpressed in prostate tumors and in prostate cancer cell lines, that the concentration of phosphorylated cofilin is higher in metastatic prostate cancer cells, and …

Sulfolipid Deficiency Does Not Affect The Virulence Of Mycobacterium Tuberculosis H37rv In Mice And Guinea Pigs, Cécile Rousseau, Oliver C. Turner, Erik Rush, Yann Bordat, Tatiana D. Sirakova, Pappachan E. Kolattukudy, Shannon Ritter, Ian M. Orme, Brigitte Gicquel, Mary Jackson

Faculty Bibliography 2000s

Lipids that are found only in the cell envelope of pathogenic mycobacteria, such as those containing multiple methyl-branched fatty acids, have long been thought to play a role in pathogenesis. Among these complex lipids, sulfolipids have been the most extensively studied over the last 50 years. The numerous biological effects exhibited by purified sulfolipids on phagocytic cells led to the idea that these molecules are probably important virulence factors facilitating the intracellular survival of Mycobacterium tuberculosis. However, definitive evidence to support this concept has been lacking. The recent construction of an isogenic sulfolipid-deficient mutant of M. tuberculosis H37Rv (Sirakova et …

Coherence Properties Near Interfaces Of Random Media, A. Apostol, A. Dogariu

Faculty Bibliography 2000s

The spatial coherence theory of optical fields radiated by statistically homogeneous, infinite, planar sources does not account for detailed surface characteristics. However, coherence properties change with the angular distribution of the intensity radiated from such a source, which, in turn, depends on the physical properties of the sample. We show that second-order correlations of the optical field measured at several wavelengths away from the surface of a highly inhomogeneous medium relate to the statistical characteristics of the interface.

The Role Of Geometric Constraints In Amphiphilic Self-Assembly: A Brownian Dynamics Study, Geuorgui K. Bourov, Aniket Bhattacharya

Faculty Bibliography 2000s

We use a stochastic molecular dynamics simulation method to investigate the effect of optimal head group area in amphiphilic self-assembly. For a fixed tail geometry, we choose several sizes of the effective head group area and carry out a detailed study of how this affects the critical micelle concentration (CMC), the cluster distribution, and the shape of micelles for different concentrations and temperature. We find that with an increase of the effective head group area, the CMC is attained at a larger concentration of the free chains at all temperatures. Likewise, for a given concentration, amphiphiles with the larger effective …

Use Of Population Viability Analysis And Reserve Selection Algorithms In Regional Conservation Plans, Carlos Carroll, Reed F. Noss, Paul C. Paquet, Nathan H. Schumaker

Faculty Bibliography 2000s

Current reserve selection algorithms have difficulty evaluating connectivity and other factors necessary to conserve wide-ranging species in developing landscapes. Conversely, population viability analyses may incorporate detailed demographic data, but often lack sufficient spatial detail or are limited to too few taxa to be relevant to regional conservation plans. We developed a regional conservation plan for mammalian carnivores in the Rocky Mountain region using both a reserve selection algorithm (SITES) and, a spatially explicit population model (PATCH). The spatially explicit population model informed reserve selection and network design by producing data on the locations of population sources, the degree of threat …

Characterization Of A Novel And Specific Inhibitor For The Pro-Apoptotic Protease Omi/Htra2, Lucia Cilenti, Younghee Lee, Sibylle Hess, Srinivasa Srinivasula, Kwon Moo Parrk, Daniela Junqueira, Hedvika Davis, Joseph V. Bonventre, Emad S. Alnemri, Antonis S. Zervos

Faculty Bibliography 2000s

Omi/HtrA2 is a mammalian serine protease with high homology to bacterial HtrA chaperones. Omi/HtrA2 is localized in mitochondria and is released to the cytoplasm in response to apoptotic stimuli. Omi/HtrA2 induces cell death in a caspase-dependent manner by interacting with the inhibitor of apoptosis protein as well as in a caspase-independent manner that relies on its protease activity. We describe the identification and characterization of a novel compound as a specific inhibitor of the proteolytic activity of Omi/HtrA2. This compound (ucf-101) was isolated in a high throughput screening of a combinatorial library using bacterially made Omi-(134-458) protease and fluorescein-casein as …

Biochemical Function Of Msl5 (Pks8 Plus Pks17) In Mycobacterium Tuberculosis H37rv: Biosynthesis Of Monomethyl Branched Unsaturated Fatty Acids, Vinod S. Dubey, Tatiana D. Sirakova, Michael H. Cynamon, Pappachan E. Kolattukudy

Faculty Bibliography 2000s

We show that the disruption of one of the mycocerosic acid synthase (mas)-like genes, msl5 (pks8 plus pks17) in Mycobacterium tuberculosis H37Rv generates a mutant incapable of producing monomethyl branched unsaturated C-16 to C-20 fatty acids that are minor constituents of acyltrehaloses and sulfolipids. The msl5 mutation did not cause any significant change in the acyl lipid composition and also did not affect growth in culture, in mouse alveolar macrophage cell line MH-S, or in the murine lung.

Potential Involvement Of Extracellular Signal-Regulated Kinase 1 And 2 In Encystation Of A Primitive Eukaryote, Giardia Lamblia - Stage-Specific Activation And Intracellular Localization, John G. Ellis Iv, Monica Davila, Ratna Chakrabarti

Faculty Bibliography 2000s

Mitogen-activated protein kinase (MAPK) pathways are major signaling systems by which eukaryotic cells convert environmental cues to intracellular events such as proliferation and differentiation. We have identified Giardia lamblia homologues of two members of the MAPK family ERK1 and ERK2. Functional characterization of giardial ERK1 and ERK2 revealed that both kinases were expressed in trophozoites and encysting cells as 44- and 41-kDa polypeptides, respectively, and were catalytically active. Analysis of the kinetic parameters of the recombinant proteins showed that ERK2 is similar to5 times more efficient than ERK1 in phosphorylating myelin basic protein as a substrate, although the phosphorylating efficiency …

A General Paradigm To Model Reaction-Based Biogeochemical Processes In Batch Systems, Yilin Fang, Gour-Tsyh Yeh, William D. Burgos

Faculty Bibliography 2000s

[1] This paper presents the development and illustration of a numerical model of reaction-based geochemical and biochemical processes with mixed equilibrium and kinetic reactions. The objective is to provide a general paradigm for modeling reactive chemicals in batch systems, with expectations that it is applicable to reactive chemical transport problems. The unique aspects of the paradigm are to simultaneously (1) facilitate the segregation (isolation) of linearly independent kinetic reactions and thus enable the formulation and parameterization of individual rates one reaction by one reaction when linearly dependent kinetic reactions are absent, (2) enable the inclusion of virtually any type of …

A Chloroplast Transgenic Approach To Hyper-Express And Purify Human Serum Albumin, A Protein Highly Susceptible To Proteolytic Degradation, Alicia Fernández-San Millán, Angel Mingo-Castel, Michael Miller, Henry Daniell

Faculty Bibliography 2000s

Human Serum Albumin (HSA) accounts for 60% of the total protein in blood serum and it is the most widely used intravenous protein in a number of human therapies. HSA, however, is currently extracted only from blood because of a lack of commercially feasible recombinant expression systems. HSA is highly susceptible to proteolytic degradation in recombinant systems and is expensive to purify Expression of HSA in transgenic chloroplasts using Shine-Dalgarno sequence (SD), which usually facilitates hyper-expression of transgenes, resulted only in 0.02% HSA in total protein (tp). Modification of HSA regulatory sequences using chloroplast untranslated regions (UTRs) resulted in hyper-expression …

Discrete Vector Solitons In Two-Dimensional Nonlinear Waveguide Arrays: Solutions, Stability, And Dynamics, J. Hudock, P. G. Kevrekidis, B. A. Malomed, Demetrios N. Christodoulides

Faculty Bibliography 2000s

We identify and investigate bimodal (vector) solitons in models of square-lattice arrays of nonlinear optical waveguides. These vector self-localized states are, in fact, self-induced channels in a nonlinear photonic-crystal matrix. Such two-dimensional discrete vector solitons are possible in waveguide arrays in which each element carries two light beams that are either orthogonally polarized or have different carrier wavelengths. Estimates of the physical parameters necessary to support such soliton solutions in waveguide arrays are given. Using Newton relaxation methods, we obtain stationary vector-soliton solutions, and examine their stability through the computation of linearized eigenvalues for small perturbations. Our results may also …

Body Image Among Older, Rural, African-American Women With Type 2 Diabetes, Leslie Sue Lieberman, Claudia K. Probart, Nancy E. Schoenberg

Faculty Bibliography 2000s

Type 2 diabetes and obesity co-occur in high prevalence among African-American women. The positive value placed on large body size has both historic and contemporary biosocial relevance. The maintenance of weight at medically recommended levels is a cornerstone of both prevention and treatment of Type 2 diabetes. This study of overweight, elderly, rural African-American women with 7 pe 2 diabetes found they generally preferred smaller body sizes compared to previous studies. Normal to slim body images as presented in a photographic array were selected as being more attractive, less likely to have diabetes and hypertension, healthier and to be more …

Hexagonal Lattice Of 10-Nm Magnetic Dots, L. Malkinski, R. E. Camley, Z. Celinski, T. A. Winningham, S. G. Whipple, K. Douglas

Faculty Bibliography 2000s

We have grown precisely ordered and precisely located arrays of ultra-small magnetic dots. The nanofabrication process is based on the use of a protein crystal etch mask which is used to create a hexagonal lattice of holes in Si substrates. An assembly of (Fe/Pd)(4) dots with the average dot size of 10 nm in diameter, 6.5 nm height, and an average separation between dot centers of 22 nm was grown using molecular-beam epitaxy. The dot locations are determined by the biological mask that is used to create ordered arrays of similar to4 nm deep holes in Si. Fe/Pd multilayers (1 …

Identification And Initial Characterization Of Three Novel Cyclin-Related Proteins Of The Human Malaria Parasite Plasmodium Falciparum, Anaïs Merckx, Karine Le Roche, Marie-Paule Nivez, Dominique Dorin, Pietro Alano, Gustavo J. Gutierrez, Angel R. Nebreda, Dean Goldring, Christina Whittle, Shelly Patterson, Debopam Chakrabarti, Christian Doerig

Faculty Bibliography 2000s

The molecular mechanisms regulating cell proliferation and development during the life cycle of malaria parasites remain to be elucidated. The peculiarities of the cell cycle organization during Plasmodium falciparum schizogony suggest that the modalities of cell cycle control in this organism may differ from those in other eukaryotes. Indeed, existing data concerning Plasmodium cell cycle regulators such as cyclin-dependent kinases reveal structural and functional properties that are divergent from those of their homologues in other systems. The work presented here lies in the context of the exploitation of the recently available P. falciparum genome sequence toward the characterization of putative …
