A Pressure Gauge Based On Gas Density Measurement From Analysis Of The Thermal Noise Of An Atomic Force Microscope Cantilever, Dongjin Seo, Mark R. Paul, Willian A. Ducker

Faculty Publications

We describe a gas-density gauge based on the analysis of the thermally-driven fluctuations of an atomic force microscope (AFM) cantilever. The fluctuations are modeled as a ring-down of a simple harmonic oscillator, which allows fitting of the resonance frequency and damping of the cantilever, which in turn yields the gas density. The pressure is obtained from the density using the known equation of state. In the range 10–220 kPa, the pressure readings from the cantilever gauge deviate by an average of only about 5% from pressure readings on a commercial gauge. The theoretical description we use to determine the pressure …

Polyamidoamine Dendrimer Nanoparticle Cytotoxicity, Oxidative Stress, Caspase Activation And Infammatory Response: Experimental Observation And Numerical Simulation, Sourav Prasanna Mukherjee, Hugh Byrne

Articles

Mechanisms underlying the in vitro cytotoxicity of Polyamidoamine nano-dendrimers in human keratinocytes are explored. Previous studies demonstrated a systematic, dendrimer-generation-dependent cytotoxicity, oxidative stress, and genotoxicity. The emerging picture is of dendrimer endocytosis, endosomal rupture and subsequent mitochondrial attack and cell death. To understand the underlying mechanisms, the evolution of reactive oxygen species, intracellular glutathione, caspase activation, mitochondrial membrane potential decay, and inflammatory responses have been examined. Early-stage responses are associated with endosomal encapsulation, later-stage with mitochondrial attack. In all cases, the magnitude and evolution of responses depend on dendrimer generation and dose. The early-stage response is modelled using a rate …

On The Growth And Exploitation Pattern Effects On The Recuperation From Overfishing Of The Red Snapper, Lutjanus Campechanus, In The Gulf Of Mexico., Vallierre K. W. Deleveaux

Open Access Dissertations

The red snapper stock in the Gulf of Mexico has been classified as severely overfished, and overfishing continues, therefore several management actions have been imposed on the Gulf red snapper fishery, including closed seasons, quotas and minimum sizes. For this reason the red snapper is often referred to as one of the most intensively managed stocks in the United States. A recovery plan for red snapper, which includes a reduction of the shrimp bycatch mortality to 50% of the 2001-2003 level, had been established so that a 20% SPR would be attained by the year 2032. Due to the very …

Population Genetics Of The Potato Psyllid, Bactericera Cockerelli, Rebekah I. Chapman

Biology Theses

The potato psyllid (Bactericera cockerelli) is native to North America and occurs from Central America to Canada. A new disease of potatoes, Zebra Chip, has recently been associated with potato psyllid occurrence. Potato psyllids transmit a gram-negative α-proteobacter, Candidatus Liberibacter solanacearum, the putative causal agent of Zebra Chip in potatoes. Symptoms of Zebra Chip first appeared in potato plants grown outside of Saltillo, Mexico in 1994, and by 2000, this invasive disease complex was found in potatoes in south Texas. Since then, Zebra Chip has spread northward, throughout the central plains of the US and on the west coast. Potato …

Risk Aversion And Former Collegiate Athletes As Financial Investors, Tyler Buccetti

College of Management Honors Theses

Risk aversion is a concept that tries to understand an individual’s choice, when two options are presented with different levels of risk and reward. This concept can be applied to finance when looking at investors decisions to invest in options with different levels of risk and returns. This study examines if having played a collegiate sport will impact the level of risk aversion an investor has. In order to determine this, an experiment was given to Graduate students working on a Master’s degree in business. The experiment consisted of six different stock options representing different levels of risk. From this …

Computer-Based Sex Education For High School Students, Ashley Jones

Evidence-Based Practice Project Reports

Adolescents are four times more likely than other age groups to contract chlamydia or gonorrhea. In the USA, young people between 15 to 24 years of age acquire almost half of all newly diagnosed sexually transmitted infections (STI) a year. The purpose of this computer-based sex education EBP project was to increase student knowledge regarding transmission, disease process, and treatment for STIs, as well as to reduce high risk sexual behaviors. The evidence-based practice model for change and the Modeling, Role-Modeling nursing theory guided this project. Computer-based sex education is supported in research. Articles critiqued, utilizing Melnyk and Fineout-Overholt (2011) …

Shoc2 Is Targeted To Late Endosomes And Required For Erk1/2 Activation In Egf-Stimulated Cells, Emilia Galperin, Lina Abdelmoti, Alexander Sorkin

Molecular and Cellular Biochemistry Faculty Publications

Shoc2 is the putative scaffold protein that interacts with RAS and RAF, and positively regulates signaling to extracellular signal-regulated protein kinases 1 and 2 (ERK1/2). To elucidate the mechanism by which Shoc2 regulates ERK1/2 activation by the epidermal growth factor (EGF) receptor (EGFR), we studied subcellular localization of Shoc2. Upon EGFR activation, endogenous Shoc2 and red fluorescent protein tagged Shoc2 were translocated from the cytosol to a subset of late endosomes containing Rab7. The endosomal recruitment of Shoc2 was blocked by overexpression of a GDP-bound H-RAS (N17S) mutant and RNAi knockdown of clathrin, suggesting the requirement of RAS activity and …

Remote Sensing-Based Time Series Models For Malaria Early Warning In The Highlands Of Ethiopia, A. Midekisa, G. Senay, G. M. Henebry, P. Semuniguse, M. C. Wimberly

Natural Resource Management Faculty Publications

Background

Malaria is one of the leading public health problems in most of sub-Saharan Africa, particularly in Ethiopia. Almost all demographic groups are at risk of malaria because of seasonal and unstable transmission of the disease. Therefore, there is a need to develop malaria early-warning systems to enhance public health decision making for control and prevention of malaria epidemics. Data from orbiting earth-observing sensors can monitor environmental risk factors that trigger malaria epidemics. Remotely sensed environmental indicators were used to examine the influences of climatic and environmental variability on temporal patterns of malaria cases in the Amhara region of Ethiopia. …

3dmolnavi: A Web-Based Retrieval And Navigation Tool For Flexible Molecular Shape Comparison., Yu-Shen Liu, Meng Wang, Jean-Claude Paul, Karthik Ramani

School of Mechanical Engineering Faculty Publications

Background

Many molecules of interest are flexible and undergo significant shape deformation as part of their function, but most existing methods of molecular shape comparison treat them as rigid shapes, which may lead to incorrect measure of the shape similarity of flexible molecules. Currently, there still is a limited effort in retrieval and navigation for flexible molecular shape comparison, which would improve data retrieval by helping users locate the desirable molecule in a convenient way.

Results

To address this issue, we develop a web-based retrieval and navigation tool, named 3DMolNavi, for flexible molecular shape comparison. This tool is based on …

Turkey’S Ministry Of National Education Study-Abroad Program: Is The Mone Making The Most Of Its Investment?, Servet Celik

The Qualitative Report

To answer an overwhelming demand for university faculty, Turkey’s Ministry of National Education (MoNE) developed a scholarship program to sponsor graduate study abroad. After completion, program recipients are expected to serve in Turkey’s universities. However, the cost of the program relative to the contributions of returning scholars has led to tremendous criticism. In order to explore whether this program is truly worth the investment, the author chose a qualitative research design to investigate the experiences of two program beneficiaries. The results revealed that their contributions were minimized by numerous institutional barriers; consequently, the system was unable to fully benefit from …

Posttraumatic Stress And Myocardial Infarction Risk Perceptions In Hospitalized Acute Coronary Syndrome Patients, Donald Edmondson, Jonathan A. Shaffer, Ellen-Ge Denton, Daichi Shimbo, Lynn Clemow

Publications and Research

Posttraumatic stress disorder (PTSD) is related to acute coronary syndrome (ACS; i.e., myocardial infarction or unstable angina) recurrence and poor post-ACS adherence to medical advice. Since risk perceptions are a primary motivator of adherence behaviors, we assessed the relationship of probable PTSD to ACS risk perceptions in hospitalized ACS patients (n = 420). Participants completed a brief PTSD screen 3-7 days post-ACS, and rated their 1-year ACS recurrence risk relative to other men or women their age. Most participants exhibited optimistic bias (mean recurrence risk estimate between "average" and "below average"). Further, participants who screened positive for current PTSD (n …

Get Your Butt Off The Ground!: Consequences Of Cigarette Waste And Litter-Reducing Methods, Joyce Lee

Pomona Senior Theses

Cigarette butts are rapidly accumulating on our planet; trillions of them are discarded every year. In this paper, I examine why cigarette litter is a problem. I first discuss the biodegradability of filters and its scientific basis, including ways to enhance degradation rates by chemically manipulating filters. I also talk about the persistence of cigarette chemicals and their potential toxic effects on children and animals. I consider other social, economic, and environmental consequences of cigarette filters and chemicals. Furthermore, I discuss various solutions smokers and non-smokers alike have created to address the problem of cigarette litter; these methods come from …

Agricultural Efficiency And The End Of The Oil Age; Building A Future Of Longevity, Keith Mchugh

Pomona Senior Theses

This thesis uses an efficiency analysis of agricultural systems to assert that, in lieu of rising prices of fossil fuel, people need to come into more direct contact with their food systems. With a switch to smaller, more efficient farms that rely less on fossil fuel and are connected with the communities they supply for, we can avoid an energy crisis turning into a famine. These smaller-scale systems can help create self-contained, carbon-neutral communities.
