Iota-Carrageenan Hydrolysis By Pseudoalteromonas Carrageenovora Ifo12985, Bernadette M. Henares, Erwin P. Enriquez, Fabian M. Dayrit, Nina Rosario L. Rojas

Chemistry Faculty Publications

We report iota-carrageenan hydrolysis by Pseudoalteromonas carrageenovora IFO 12985. Kappa-carrageenase and lambda-carrageenase were previously isolated from this organism, but iota-carrageenase activity had not been reported in the literature. P. carrageenovora was grown in iota-carrageenan-based liquid medium. Using the zone of depression assay, transfer of aliquots of the culture to solid medium with 2% iota- and kappa-carrageenan showed extensive hydrolysis of iota-carrageenan. Analysis of the hydrolysates by C-13 Nuclear Magnetic Resonance spectroscopy confirmed degradation of the iota-carrageenan. Hydrolytic activity of P. carrageenovora grown in iota-carrageenan was compared with that of the same organism grown in kappa-carrageenan. Cell-free supernatants from each yielded …

A Fiber Bragg Grating-Based All-Fiber Sensing Systems For Telerobotic Cutting Applications, Ginu Rajan, Dean Callaghan, Yuliya Semenova, Mark Mcgrath, Eugene Coyle, Gerald Farrell

Articles

A fiber Bragg grating (FBG)-based strain sensing system for minimally invasive telerobotic cutting applications is presented in this paper. Investigations assume that a scissor blade can be approximated as a uniformly tapered cantilever beam. A replica of the scissor blade is produced and strain characterization has been carried out using an FBG sensor system. Results are validated against measurements obtained using conventional electrical resistance strain gauges. The scissor blade experiences both direct and lateral forces during cutting, hence the system is characterized for a direct load range of 0-30 N and a lateral load range of 0-10 N. The results …

Combining Mobile Technologies For Accurate, Open Source, Privacy Sensitive, Zero Cost, Location Determination, Seamus Rooney

Doctoral

Determining the location of an object or individual using a mobile device (e.g. cell phone) is an important aspect of modern information gathering. Various solutions have been proposed which all have their strengths and weaknesses. To date, no solution has been devised for a mobile device that will work effectively in multiple environments and without assistance from network-provider connections1. To address this, it is argued that the current state of the art can be advanced using a hybrid approach that combines a number of sensor technologies to provide a more reliable, and accurate mobile location determination that functions in multiple …

Applications Of Site-Specific Recombination Systems In Transgene Expression And Marker Gene Removal, Mehmet Aydin Akbudak

Graduate Theses and Dissertations

Site Specific Recombination systems, such as FLP-FRT and Cre-lox, have been successfully used for site-specific gene integration and marker-gene deletion in plant systems. They are very useful tools in the integration of single-copy full-length transgene cassettes into the genome because the transgene integration via conventional methods often generate multi-copy locus. Such complex locus containing direct and inverted repeats of full-length and truncated copies of the transgene cassette generate aberrant RNA resulting in gene silencing. Therefore, for stable gene expression, a single copy transgene locus is preferred. However, even single copy locus sometimes succumbs to gene silencing. Although the mechanism is …

Analysis Of The Response Of Medicago Truncatula Calcium Oxalate Mutants To Abiotic Stress, Wayra Gabriela Navia-Gine

Graduate Theses and Dissertations

Calcium oxalate crystals are found in most plant species. In Medicago truncatula wild-type A17, crystals accumulate in leaves along the secondary veins and the only role attributed to them so far is defense against chewing insects. Calcium oxalate deficient (cod) mutants were isolated in M. truncatula; the cod mutants include cod5, which completely lack crystals in the leaves and cod6 that accumulates fewer and smaller crystals compared to A17. We analyzed gene expression in the cod mutants and A17 using GeneChip® Medicago Genome Arrays and found important differences in transcriptome between the three genotypes. In particular, we found a gene …

Reframing Antitrust In Light Of Scientific Revolution: Accounting For Transaction Costs In Rule Of Reason Analysis, Alan J. Meese

UC Law Journal

This Article contends that modern rule of reason analysis, informed by workable competition’s partial equilibrium trade-off paradigm, is suitable for evaluating only a subset of agreements that may reduce transaction costs. The Article distinguishes between “technological” and “non-technological” transaction costs. Technological transaction costs entail the bargaining and information costs first emphasized by Ronald Coase, while non-technological transaction costs result from more fundamental departures from perfect competition, departures creating a risk of opportunism that accompanies relationship-specific investments. Modern law does accurately assess restraints that may reduce technological transaction costs—costs that are analogous to the sort of production costs recognized by the …

Intrusion Detection And Prevention System: Sql-Injection Attacks, Varian Luong

Master's Projects

Personally identifiable information (PII) is information regarding things such as bank accounts, retirement or stock investment accounts, credit card accounts, medical records, or insurance claims. There is a need to protect the PII in databases that are connected to the ubiquitous, global network that is the Internet. If there is any vulnerability in the protection in a system that holds PII, then it presents an opportunity for an unauthorized person to access this PII. One of the techniques available to would- be information thieves is SQL injection (SQL-I). In this project, a system is developed to analyze the values submitted …

Understanding Gender Differences In Media Perceptions: A Comparison Of 2d Versus 3d Media, Fiona Fui-Hoon Nah, David Dewester, Brenda Eschenbrenner

Research Collection School Of Computing and Information Systems

We examine gender differences in 2D versus 3D media perceptions. Using the Hunter-Gatherer Theory of Spatial Gender Differences and Jung’s Theory of Psychological Types, we hypothesize differences in men’s and women’s perceptions of skill, challenge, telepresence, and satisfaction with online experiences in 2D versus 3D media interaction. The findings suggest that even though women perceive lower skill levels and greater challenges in using 2D and 3D media than men, women’s sense of telepresence is higher than men in both 2D and 3D media. Women are also more satisfied with their interaction in 2D and 3D media than men.

Hybrid Nanomanufacturing Process For High-Rate Polymer Nanofiber Production, Chad T. Peterson

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

Nanotechnology and nanomaterials have the potential to revolutionize existing and create entirely new industries. Unique physical, mechanical, chemical, and biological properties of nanomaterials have been extensively documented in the last two decades. However, most nanomaterials are discontinuous in nature, creating problems with their processing and manipulation into devices and raising health concerns. Continuous nanofibers represent an emerging class of nanomaterials with critical advantages to applications. Continuous nanofibers are readily produced by electrospinning process comprising spinning polymer solutions in high electric fields. Electrospinning is a very economic top-down nanomanufacturing process that has been used to produce ultrafine continuous nanofibers from several …

Anomalous Loss Of Toughness Of Work Toughened Polycarbonate, Shawn E. Meagher

Department of Engineering Mechanics: Dissertations, Theses, and Student Research

Glassy polymers such as polycarbonate (PC) can be toughened through compressive plastic deformation. The increase in toughness is substantial, showing as much as a fifteen fold increase in the amount of dissipated energy during failure for samples compressed to 50% plastic strain. This toughness increase can be reversed through thermal aging at temperatures below the glass transition temperature (T_g = 147°C).

The combined effect of plastic compression and thermal aging has been studied using Charpy, Single Edge Notch Bending (SENB), and Compact Tension (CT) tests. The tests mapped the response of samples cut along different orientations relative to the …

Improved Mobile Wireless In Vivo Surgical Robots: Modular Design, Experimental Results, And Analysis, Jeff Hawks

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Laparoscopic surgery results in superior patient outcomes as measured by less painful recovery and an earlier return to functional health compared to conventional open surgery. However, the difficulty of manipulating laparoscopic tools from outside the patient’s body generally limits these benefits to patients undergoing relatively simple procedures. The use of miniature in vivo robots that fit entirely inside the peritoneal cavity represents a novel approach to laparoscopic surgery. These robots enable more complex laparoscopic procedures, increasing the number of patients that benefit from laparoscopic surgery.

This thesis describes recent work focused on developing a modular wireless mobile platform that can …

A Metrical Analysis And Rebarring Of Paul Creston's Sonata For Alto Saxophone And Piano, Op. 19, Christopher Kyle Sweitzer

Glenn Korff School of Music: Dissertations, Theses, Student Creative Work, and Performances

The Sonata For Alto Saxophone and Piano Op. 19 is one of the most popular pieces in the saxophone literature, commonly played by professional saxophonists during their training. It features exciting rhythmic devices like irregular and mixed meter, the notation of which is the main focus of this paper. Although Creston often used irregular and mixed meter in his compositions, he rarely specifically notated them, choosing instead to use accents, beams, slurs, and other phenomenal cues at the musical surface to create the effect of these metric plans. Time signatures often remained constant throughout entire movements. Creston believed this would …
