The Comet Assay To Determine The Mode Of Cell Death For The Ultrasonic Delivery Of Doxorubicin To Human Leukemia (Hl-60 Cells) From Pluronic P105 Micelles, Ghaleb A. Husseini, Kim L. O'Neill, William G. Pitt Feb 2006

The Comet Assay To Determine The Mode Of Cell Death For The Ultrasonic Delivery Of Doxorubicin To Human Leukemia (Hl-60 Cells) From Pluronic P105 Micelles, Ghaleb A. Husseini, Kim L. O'Neill, William G. Pitt

Faculty Publications

This notes examines the mode of cell death of HL-60 cells exposed to 70 kHz and 1.3 W/cm2 in the presence of 1% Pluronic P105 and 1.67 μg/ml doxorubicin (Dox). The cells were ultrasonicated for 30, 60 and 120 minutes. They were then lysed, electrophorised, stained using propidium iodide, and their DNA profile captured using a fluorescent microscope. The gradual DNA damage observed and the comet tails captured after 1 and 2 hours of insonation suggest that the mode of cell killing is apoptosis.


A Qualitative Study Of The Supports Women Find Most Beneficial When Dealing With A Spouse's Sexually Addictive Or Compulsive Behaviors, Jill Christine Manning Feb 2006

A Qualitative Study Of The Supports Women Find Most Beneficial When Dealing With A Spouse's Sexually Addictive Or Compulsive Behaviors, Jill Christine Manning

Theses and Dissertations

While not included in the diagnostic classifications of sexual disorders in the Diagnostic and Statistical Manual of Mental Disorders (DSM), sexual addictions and compulsivities are increasingly being encountered by mental health professionals, and the field of sexual addictions is gaining wider acceptance (Delmonico & Carnes, 1999; Garos, 1997). Research shows the majority of people struggling with sexual addictions and compulsivities involving the Internet are married, heterosexual males (Cooper, Delmonico, & Burg, 2000), and that women who are married to these men are directly impacted by this problem (Schneider, 2000b). Although there is research on many issues relating to wives of …


Using Augmented Virtuality To Improve Human-Robot Interactions, Curtis W. Nielsen Feb 2006

Using Augmented Virtuality To Improve Human-Robot Interactions, Curtis W. Nielsen

Theses and Dissertations

Mobile robots can be used in situations and environments that are distant from an operator. In order for an operator to control a robot effectively he or she requires an understanding of the environment and situation around the robot. Since the robot is at a remote distant from the operator and cannot be directly observed, the information necessary for an operator to develop an understanding or awareness of the robot's situation comes from the user interface. The usefulness of the interface depends on the manner in which the information from the remote environment is presented. Conventional interfaces for interacting with …


Characterization, Functionalization And Applications Of Alkyl Monolayers On Silicon Surfaces, Guilin Jiang Feb 2006

Characterization, Functionalization And Applications Of Alkyl Monolayers On Silicon Surfaces, Guilin Jiang

Theses and Dissertations

Investigations were performed on the stability, mechanism of formation and an application of alkyl monolayers chemomechanically prepared on silicon surfaces. A new method of surface modification, laser-activation modification of surfaces (LAMS), and multivariate analyses of time-of-flight secondary ion mass spectrometry (ToF-SIMS) images of LAMS spots were also reported. X-ray photoelectron spectroscopy (XPS) and other data show that alkyl monolayers prepared by scribing silicon under 1-iodoalkanes and 1-alkenes were stable over extended periods of time to air, water, a boiling acid and Al Ka X-rays. The stability is attributed to direct Si-C bonding in the monolayers. The observation that the oxygen …


A Propensity For Genius: That Something Special About Fritz Zwicky (1898 - 1974), John Charles Mannone Feb 2006

A Propensity For Genius: That Something Special About Fritz Zwicky (1898 - 1974), John Charles Mannone

Swiss American Historical Society Review

It is difficult to write just a few words about a man who was so great. It is even more difficult to try to capture the nuances of his character, including his propensity for genius as well as his eccentric behavior edging the abrasive as much as the funny, the scope of his contributions, the size of his heart, and the impact on society that the distinguished physicist, Fritz Zwicky (1898- 1974), has made. So I am not going to try to serve that injustice, rather I will construct a collage, which are cameos of his life and accomplishments. In …

Settling-Time Improvements In Positioning Machines Subject To Nonlinear Friction Using Adaptive Impulse Control, Tim Hakala Jan 2006

Settling-Time Improvements In Positioning Machines Subject To Nonlinear Friction Using Adaptive Impulse Control, Tim Hakala

Theses and Dissertations

A new method of adaptive impulse control is developed to precisely and quickly control the position of machine components subject to friction. Friction dominates the forces affecting fine positioning dynamics. Friction can depend on payload, velocity, step size, path, initial position, temperature, and other variables. Control problems such as steady-state error and limit cycles often arise when applying conventional control techniques to the position control problem. Studies in the last few decades have shown that impulsive control can produce repeatable displacements as small as ten nanometers without limit cycles or steady-state error in machines subject to dry sliding friction. These …


Remote Terrain Navigation For Unmanned Air Vehicles, Stephen R. Griffiths Jan 2006

Remote Terrain Navigation For Unmanned Air Vehicles, Stephen R. Griffiths

Theses and Dissertations

There are many applications for which small unmanned aerial vehicles (SUAVs) are well suited, including surveillance, reconnaissance, search and rescue, convoy support, and short-range low-altitude perimeter patrol missions. As technologies for microcontrollers and small sensors have improved, so have the capabilities of SUAVs. These improvements in SUAV performance increase the possibility for hazardous missions through mountainous and urban terrain in the successful completion of many of these missions. The focus of this research was on remote terrain navigation and the issues faced when dealing with limited onboard processing and limited payload and power capabilities. Additional challenges associated with canyon and …


Fuel-Nox Formation During Low-Grade Fuel Combustion In A Swirling-Flow Burner, Chunyang Wu Jan 2006

Fuel-Nox Formation During Low-Grade Fuel Combustion In A Swirling-Flow Burner, Chunyang Wu

Theses and Dissertations

Insufficient knowledge of fireside behavior in the near-burner region during biomass combustion is one of major factors preventing widespread use of this renewable fuel in pulverized coal power plants. The current research is aimed to investigate the impact of biomass cofiring on NO formation in the near-burner region through interpretation of computational fluid dynamics (CFD) predictions and data collected from a series of biomass tests in a pilot-scale (0.2 MW), swirling flow burner. Two-dimensional gas species mole fraction data were collected with state-of-theart instruments from nine experiments, composing one herbaceous biomass (straw), one woody biomass (sawdust), a low sulfur sub-bituminous …


Characterization Of The Role Of Sox9 In Cartilage-Specific Gene Regulation, Mary Ann Genzer Jan 2006

Characterization Of The Role Of Sox9 In Cartilage-Specific Gene Regulation, Mary Ann Genzer

Theses and Dissertations

Although advances have been made toward understanding the complex mechanisms that regulate the process of DNA transcription, the specific mechanisms of activation for many individual genes remain unknown. In this study, we focus on the role the transcription factor SOX9 plays in activating cartilage-specific genes, specifically Col9a1 and Cartilage Link Protein (CRTL1). Previously, enhancers of these genes containing single SOX9 binding sites were shown to be activated through SOX9 binding. However, the hypothesis was made that in cartilage-specific genes dimeric SOX9, as opposed to monomeric SOX9, is necessary for activation. We identified a putative binding site adjacent to each of …

The data was collected through surveys, observations, interviews, and evaluations. The researcher concluded the following from the study; 92% of the students were actively participating in the two week service project, 76% of the students …


A Framework For An Implantable Wireless Pressure And Volume Sensor Focusing On The Diagnosis And Treatment Of Shunt Failure In Hydrocephalus Patients, Donald Monte Wichern Jan 2006

A Framework For An Implantable Wireless Pressure And Volume Sensor Focusing On The Diagnosis And Treatment Of Shunt Failure In Hydrocephalus Patients, Donald Monte Wichern

Theses and Dissertations

The framework for a permanently implantable wireless compliance sensor was developed and validated using laboratory experiments. The proposed sensor would measure the intracranial pressure and fluid volume in the brain and return this information to a monitoring device. The designed sensor received power remotely from the monitoring device negating the need for an implanted power source. Impedance measurement estimation techniques were suggested, studied and applied to the compliance sensing system. A new impedance measurement technique, accounting for multiple variability in the domain, was developed. An extensive simulation environment was designed and used to develop the laboratory experiments and hardware. The …


A User-Centric Tabular Multi-Column Sorting Interface For Intact Transposition Of Columnar Data, David B. L. Miles Jan 2006

A User-Centric Tabular Multi-Column Sorting Interface For Intact Transposition Of Columnar Data, David B. L. Miles

Theses and Dissertations

Many usability features designed in software applications are not procedurally intuitive for software users. A good example of software usability involves tabular sorting in a spreadsheet. Single-column sorting, activated with a mouse click to a column header or toolbar button, often produces rearranged listings that reduce cognitive organization beyond the sorted column. Multi-column sorting, generated through menu-driven processes, provides derived organization, however, locating feature options through menu-based systems can be confusing. A means to overcome this confusion is prioritized selection of database arrays issued to columnar displays for the purpose of intact transposition of data. This is a unique process …

What Can We Learn From Danish Farmers?, Palle Pedersen Jan 2006

What Can We Learn From Danish Farmers?, Palle Pedersen

The Bridge

During the past 100 years, Danish agriculture has developed its position and ability to compete on international markets. Since Denmark joined the European Economic Community in 1973, productivity in Danish agriculture has increased considerably; and, with a food production sufficient for 15 million people and a population of only 5.2 million, Denmark exports two-thirds of it agricultural production to more than 180 countries. Overall, Denmark is the largest food exporter in the world relative to its population.1


The Reception Of Danish Science Fiction In The United States, Kristine J. Anderson Jan 2006

The Reception Of Danish Science Fiction In The United States, Kristine J. Anderson

The Bridge

Science fiction is a distinctly American genre. Although scholars have traced its origins back as far as the Latin writer Lucian of Samosata,1 it was Hugo Gernsback, a publisher of pulp magazines in the United States, who first gave the genre its name in the June 1929 issue of Wonder Stories. Gernsback had been serializing the scientific romances of such writers as Jules Verne and HG. Wells, emphasizing their treatment of technology and putting them forth as models for other budding writers to imitate. The magazines that Gernsback initiated became very popular, spawning more from other publishers. Groups of aficionados …

Conference Opening Remarks, Lene Balleby Jan 2006

Conference Opening Remarks, Lene Balleby

The Bridge

When I first heard about this year's conference, it was being launched as a celebration and recognition of two of Denmark's most famous sons: Hans Christian Andersen and Soren Kirkegaard. But looking at the extensive program for the upcoming days, it is clear that this program is also meant to present a much wider picture of the richness and scope of Danish culture and that it will indeed live up to its title: "Danish Culture, Past and Present."


Danish Nobel Laureates In Literature With Special Emphasis On Johannes V. Jensen, Erik M. Christensen Jan 2006

Danish Nobel Laureates In Literature With Special Emphasis On Johannes V. Jensen, Erik M. Christensen

The Bridge

Religion, Philosophy, and Art are related. Sometimes more than other. They are so much in family, in fact, that they are able to become one. This may even happen without being intended or even realized, but we also have, in Western civilization, instances where the artist very clearly meant his work to represent a unity of Religion, Philosophy, and Art. The greatest known instance of this is, of course, Dante Alighieri's poem La Divina Commedia (ca. 13071320), the story of his wandering through Purgatory, down to Hell, and up to Paradise where his ideal love for Beatrice allows him to …


Estimation Of Aquifer Hydraulic Characteristics From Electrical Sounding Data: The Case Of Middle Imo River Basin Aquifers, South- Eastern Nigeria. Jan 2006

Estimation Of Aquifer Hydraulic Characteristics From Electrical Sounding Data: The Case Of Middle Imo River Basin Aquifers, South- Eastern Nigeria.

Journal of Spatial Hydrology

We have used the concept of Da - Zarrouk parameters (transverse unit resistance (R) and longitudinal conductance (C)) in porous media to determine aquifer hydraulic characteristics within the middle Imo river basin. The lithostratigraphic units within the study area include: Imo formation, Bende - Ameki formation, Ogwashi Asaba formation and Benin formation. The direct current electrical resistivity method was utilized for the present study. Twenty-four (24) vertical electrical soundings (VES) using the Schlumberger array was acquired for the study area. A maximum current electrode spacing (AB) of 1000 meters was used. Eight of the soundings were carried out near existing …

Blended Learning Systems Definition, Current Trends, And Future Directions, Charles R. Graham Jan 2006

Blended Learning Systems Definition, Current Trends, And Future Directions, Charles R. Graham

Faculty Publications

The term blended learning is being used with increased frequency in both academic and corporate circles. In 2003, the American Society for Training and Development identified blended learning as one of the top ten trends to emerge in the knowledge delivery industry (Rooney, 2003). In 2002, the Chronicle of Higher Education quoted the president of Pennsylvania State University as saying that the convergence between online and residential instruction was “the single-greatest unrecognized trend in higher education today” (Young, 2002, p. A33). Also quoted in that article was the editor of the Journal of Asynchronous Learning Networks, who predicted a dramatic …

Many privately held companies aspire to go public through an initial public offering. But the IPO process is time-consuming, expensive, and fraught with uncertainty. With the aim of shedding light on the process and reducing at least some of the uncertainty, the authors asked several hundred CFOs to share their experiences and perceptions with regard to six specific aspects of the IPO process: (1) motives for going public; (2) the timing of IPOs; (3) criteria for choosing an underwriter; (4) cause of IPO underpricing; (5) IPO signaling; and (6) reasons to stay private.
