A Standoff Approach To Monitoring Infant Apnea, Lauren J. West
Master's Theses
The focus of this thesis was to capture and measure carbon dioxide concentrations upon exhalation to determine if an apnea event is occurring. Research in the fields of respiratory physiology and apnea built the foundation for the design of the standoff infant apnea monitor. The monitor is designed to track infant respiration using carbon dioxide and sound signatures of breath without touching the infant. Each detection system, audio and carbon dioxide, were designed separately and brought together for a final proof-of-concept device. The software was developed using LabView and run on a Netbook. Testing was conducted on healthy adults to …

Commissioning An Anthropomorphic Spine And Lung Phantom For Remote Dose Verification Of Institutions Participating In Rtog 0631, Douglas F. Caruthers
Dissertations and Theses (Open Access)
The RPC developed a new phantom to ensure comparable and consistent radiation administration in spinal radiosurgery clinical trials. This study assessed the phantom’s dosimetric and anatomic utility. The ‘spine phantom’ is a water filled thorax with anatomy encountered in spinal radiosurgery: target volume, vertebral column, spinal canal, esophagus, heart, and lungs. The dose to the target volume was measured with axial and sagittal planes of radiochromic film and thermoluminescent dosimeters (TLD). The dose distributions were measured with the radiochromic film calibrated to the absolute dose measured by the TLD. Four irradiations were administered: a four angle box plan, a seven …

Preosteoblast Behavior On A Synthetic Calcium Phosphate Scaffold Coated With Cell Derived Matrix, Daniel A. Young
Theses and Dissertations (ETD)
Bone grafts are commonly used for the treatment of large bone defects. Biodegradable, synthetic bone grafts combined with cells and growth factors as a tissue engineered construct can provide benefits over the common autografts and allografts currently used. Calcium phosphate (CaP) materials offer high biocompatibility and chemical similarity to natural bone tissue. Biodegradable beta-tricalcium phosphate (β-TCP) scaffolds with an interconnected porous network have been created to promote tissue ingrowth and regeneration in vitro and in vivo. Extracellular matrix (ECM) coated on titanium and polymer scaffolds has been shown to improve cell response to those material surfaces. Here, we attempted …
Enhancing Student Usability Of The Osmette,

Enhancing Student Usability Of The Osmette, Mitchell Foutz
Biomedical Engineering
Precision Systems' Micro-Osmette located in the St. Jude Lab at Cal Poly SLO is a freezing-point depression osmometer capable of measuring the osmolality, the concentration of hydrated species in osmoles per-kilogram of water, with unrivaled speed and accuracy. The Osmette could be used extensively by students in a wide variety of applications if students are able to become acquainted with the device in an accelerated manner. The amount of time required to safely and effectively operate the micro-Osmette using the operator's manual provided with the device is prohibitive of widespread use by students. Revisions and improvements to the existing operator's …

The present invention provides compounds, methods and systems for sequencing nucleic acid using single molecule detection. Using labeled NPs that exhibit charge-switching behavior, single-molecule DNA sequencing in a microchannel sorting system is realized. In operation, sequencing products are detected enabling real-time sequencing as successive detectable moieties flow through a detection channel. By electrically sorting charged molecules, the cleaved product molecules are detected in isolation Without interference from unincorporated NPs and Without illuminating the polymerase-DNA complex.

Segmentation Of Thermographic Images Of Hands Using A Genetic Algorithm, Payel Ghosh, Judith Gold, Melanie Mitchell
Computer Science Faculty Publications and Presentations
This paper presents a new technique for segmenting thermographic images using a genetic algorithm (GA). The individuals of the GA also known as chromosomes consist of a sequence of parameters of a level set function. Each chromosome represents a unique segmenting contour. An initial population of segmenting contours is generated based on the learned variation of the level set parameters from training images. Each segmenting contour (an individual) is evaluated for its fitness based on the texture of the region it encloses. The fittest individuals are allowed to propagate to future generations of the GA run using selection, crossover and …

A Bland–Altman Comparison Of The Lead Care® System And Inductively Coupled Plasma Mass Spectrometry For Detecting Low-Level Lead In Child Whole Blood Samples, Christina Sobin, Tanner Schaub, Natali Parisi, Eva De La Riva
Selected Works Temporary Series
Chronic childhood lead exposure, yielding blood lead levels consistently below 10 μg/dL, remains a major public health concern. Low neurotoxic effect thresholds have not yet been established. Progress requires accurate, efficient, and cost-effective methods for testing large numbers of children. The LeadCare® System (LCS) may provide one ready option. The comparability of this system to the “gold standard” method of inductively coupled plasma mass spectrometry (ICP-MS) for the purpose of detecting blood lead levels below 10 μg/dL has not yet been examined. Paired blood samples from 177 children ages 5.2–12.8 years were tested with LCS and ICP-MS. Triplicate repeat tests …

Electromyographic Analysis Of Trunk Muscle Activation During A Throwing Pattern Following Rotator Cuff Mobilization, Aubrey L. Doede
CMC Senior Theses
Correct muscular activation of the body segments during an overhand throw is achieved when movement originates in the larger and more proximal legs and trunk and moves sequentially to the smaller, distal segments of the shoulder and arm. This sequence permits angular velocity to transfer progressively through the throw as part of an open kinetic chain. The athlete can summate angular velocity and segmental forces only if he is able to create a separation between the body segments during the movement pattern, and this separation is thus essential to effective segmental sequencing for activation of the trunk muscles to occur …
