The Future Of Nuclear Security: A Medical Physicist’S Perspective, Katharine E. Thomson

International Journal of Nuclear Security

Planning for the future of nuclear security is a vital and complex task, requiring cooperation and contribution from many disciplines and industries. This diversity of expertise should include the medical sector, which faces many of the same challenges as the nuclear industry: controlling access to dangerous material, creating a strong security culture, cooperating with the wider world and engaging the public.

Medical physicists, of which the author is one, oversee all aspects of small-scale radiation use. This paper discusses three key areas increasingly important to both medical and nuclear uses of radioactive materials: public engagement, prevention of nuclear and radiological …

Proposed Method For Measuring The Let Of Radiotherapeutic Particle Beams, Stephen D. Bello

Physics & Astronomy ETDs

The Bragg peak geometry of the depth dose distributions for hadrons allows for precise and effective dose delivery to tumors while sparing neighboring healthy tissue. Further, compared against other forms of radiotherapeutic treatments, such as electron beam therapy (EBT) or photons (x and \(\gamma\)-rays), hadrons create denser ionization events along the particle track, which induces irreparable damage to DNA, and thus are more effective at inactivating cancerous cells. The measurement of radiation's ability to inactivate cellular reproduction is the relative biological effectiveness (RBE). A quality related to the RBE that is a measurable physical property is the linear energy transfer …

Characterization Of Different Molecular Markers For Identification Of Salmonella Enterica Serovar Typhi In Pakistani Population, Faizan Muttiullah, Fida Muhammad Khan, Fakhar-I- Abbas, Sabiha Shamim

Journal of Bioresource Management

Typhoid is caused by Salmonella enterica serovar Typhi that is usually diagnosed by using serologic and immuno-chromatographic techniques in developing counties including Pakistan, which is thought to be an unreliable diagnostic method. For accurate diagnosis we used molecular techniques to amplify 204 bp StyR-36 and 498 bp flagellin gene for the identification of Salmonella enterica serovar Typhi. This study was done on 58 individuals diagnosed positive of typhoid via serologic tests and 50 healthy individuals as a control group. Success rate of amplification for flagellin gene was 77.58% while that for StyR-36 gene was 68.97% showing that flagellin gene primer …

Gadgets And Grieving: A Chronological Analysis On The Ways In Which Advancements In Medical Technologies Have Altered The Grieving Process, Grace Mcnair

Dialogue & Nexus

Since the 1940s, both end-of-life care and advancements in medical technologies have expanded exponentially. This article explores the advancements in medical technologies and how these have altered the way that Western society grieves death. With the capabilities to prolong life, the family, the patient, and the medical team, all grieve the end of life in different ways. This article provides a chronological analysis of palliative care, hospice care, and various medical advancements. These changes in medicine are then paralleled with alterations in the bereavement process. This article explores historical narratives of Western society’s transformation of grief through the lens of …

The Design Of An Instrument To Assess Clinical Laboratories Efficacy Post Implementation Of The Patient Protection Affordable Care Act, Harry Mcdonald Jr.

Dissertations

The healthcare system in the United States has undergone substantial changes in support of the Patient Protection and Affordable Care Act (PPACA). On March 23, 2010, the implementation of the new healthcare law brought universal healthcare access to all Americans, while attempting to increase quality and decrease medical costs. The new law promotes more of a quality-focused, outcome-based model rather than a pay-for-fee service model; thus, moving the paradigm from infrequent to preemptive healthcare. The PPACA postulates as the only way to achieve cost savings while increasing quality and access. Never before has there been such an extensive change to …

Post-Intensive Care Syndrome: Comparison Of Educational Interventions To Educate Parents Of Children Hospitalized In The Pediatric Intensive Care Unit At St. Louis Children’S Hospital, Stephanie A. Esses

Dissertations

Background: Family members of children hospitalized in the pediatric intensive care unit (PICU) can develop cognitive, psychological, and physical manifestations of post-intensive care syndrome (PICS). Targeted education to help parents/caregivers recognize the signs and symptoms of PICS may result in better awareness of the syndrome and greater willingness to seek and receive support during their child’s PICU admission.

Objective: to evaluate three targeted PICS educational interventions to increase PICS awareness among parents/caregivers in the St. Louis Children’s Hospital (SLCH) PICU.

Results: A total of 62 parents/caregivers received one of three educational interventions: informational brochures (n=22), scripted informational conversation (n=20), or …

Undergraduate Research On General Aviation Hypoxia: A Student’S Perspective, Claire Schindler

Discovery Day - Prescott

During the fall academic term of 2016, an opportunity arose through the College of Aviation to serve as an undergraduate research assistant. Through discussion with faculty mentors, it was decided that a severely overlooked aspect of the aviation industry was survivors of hypoxia, especially in the less regulated general aviation community. The problem this study addresses is the uncertainty of the common circumstances that general aviation pilots find themselves in that create a hypoxic state, as well as whether or not that pilot reported the occurrence to the proper establishments. The results of this study showed not only those that …

Comparison Of Atypical Bacteriophages That Infect Caulobacter Crescentus, Doreen Nguyen

Theses and Dissertations

Several Caulobacter bacterial genomes have been recently sequenced, and all of the genomes contained one or more clusters of genes with phage origins. This observation indicates that bacteriophages contribute to the Caulobacter gene pool, so in order to understand bacteria genomes we will need to understand phage genomes as well. As part of understanding the phage genomes, we want to isolate novel bacteriophages and study their genomics. This study resulted in the isolation of 12 new phages, including four that differ from the well-studied CbKlike phages. Two of these novel phages are Podoviruses with icosahedral heads and small tails, and …

Environmental Relationships And Predator-Prey Interactions Within The Snapper-Grouper Complex In The Southeastern U.S. Atlantic – Implications For Fisheries Management, Dawn M. Glasgow

Theses and Dissertations

Stock assessments indicate many valuable fish species are declining, or are considered overfished and/or are undergoing overfishing. Fisheries scientists and managers in the southeastern U.S. typically have utilized a single-species approach, and relied on catch per unit effort data derived from fishery-independent surveys to determine indices of abundance for economically important reef fish. However, catchability for these surveys vary for many reasons including environmental and predator-prey relationships. This research was developed to elucidate environmental influences on reef fish assemblages and distribution of reef-associated marine predators, and examine predator-prey dynamics that may influence relative abundance of large predators based on chevron …
