In Vivo X-Ray Fluorescence Of Bone Lead In The Study Of Human Lead Metabolism In A Cohort Of The General Population And Smelter Employees, Sepideh Behinaein 2014 McMaster University

In Vivo X-Ray Fluorescence Of Bone Lead In The Study Of Human Lead Metabolism In A Cohort Of The General Population And Smelter Employees, Sepideh Behinaein

Open Access Dissertations and Theses

After developing the clover-leaf geometry system, the system was used for the first time in a major survey in 2008 to measure the lead levels of 497 smelter employees in the province of New Brunswick in Canada, who participated in a lead study during the time interval of 14 January to 6 March 2008. Participants were measured for lead concentration in the left tibia and right calcaneus, each for 30 min. The minimum detection limit (MDL) of the clover leaf geometry detector system was improved by a factor 3.1 compared to a conventional system. Improvement of the detection system ...


Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann 2014 California Polytechnic State University

Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann

Industrial Technology

With so many studies being conducted on professional football players regarding concussions and other related brain injuries, it’s amazing that such an important demographic has been missed. While NFL players are just as subjected to serious injuries as anyone else or even more so, it is important to remember that these players are outfitted, in most cases, with top-of-the-line equipment -- especially their helmets. If the focus is shifted to a younger demographic, youth football players in middle school and high school, the equipment is far less advanced and in a vast majority of cases, has been previously used by ...


Benjamin Banneker's Original Handwritten Document: Observations And Study Of The Cicada, Janet E. Barber, Asamoah Nkwanta 2014 Claremont Colleges

Benjamin Banneker's Original Handwritten Document: Observations And Study Of The Cicada, Janet E. Barber, Asamoah Nkwanta

Journal of Humanistic Mathematics

Benjamin Banneker, farmer, mathematician, astronomer, and scientist, is known for his mathematical puzzles, ephemeris calculations, almanacs, his wooden clock, land surveying work, and famous letter on human rights. However, as a naturalist, his scientific and systematic observations of the cicadas are less known. In this paper we publicize Banneker’s naturalistic study of the seventeen-year periodic cycle of the cicada and make available the original handwritten document of his observations. We also introduce the audience of this journal to an intriguing natural problem involving prime numbers.

Acceptance Of The Autonomy Required For Interplanetary Small Spacecraft Missions By The Scientists Who Will Use The Data, Jeremy Straub 2013 SelectedWorks

Acceptance Of The Autonomy Required For Interplanetary Small Spacecraft Missions By The Scientists Who Will Use The Data, Jeremy Straub

Jeremy Straub

Small spacecraft operating at a distance from Earth are constrained by communications in several ways. The delay between message trans- mission, receipt at Earth, and eventual receipt of a reply can be significant. Further, gain and transmission power limitations (introduced by spacecraft form factor constraints and the resulting limitation on antenna size and power generation capabilities) constrain the amount of data that can be sent and received. This drives a need for mission autonomy: a requirement that the spacecraft be able to manage its own operations and choose the data that it should collect and transmit, based on high-level instructions ...


Investigating Uranus With George: The Gap-Based Expanding Outer Region Geophysical Explorer Mission, Jeremy Straub, Josh Berk, Tyler Hill, Nick Long 2013 SelectedWorks

Investigating Uranus With George: The Gap-Based Expanding Outer Region Geophysical Explorer Mission, Jeremy Straub, Josh Berk, Tyler Hill, Nick Long

Jeremy Straub

This paper presents an overview of a two-part mission to Uranus and its moons. Key questions about the Uranian system remain unanswered which can and should be resolved by this mission. These include gaining an understanding about the offset of Uranus’s magnetic field and its axial tilt. Additional details about the composition and formation of Uranus’s moons are also desired. The mission will be comprised of a primary craft and three 6-U CubeSats. The CubeSats will initially be deployed in Uranian orbit to perform a characterization of the gravity field of the planet. They will then be moved ...


Uranian Moon Investigation With “Hitchhiker” Small Spacecraft, Jeremy Straub, Tyler Hill, Josh Berk, Nick Long 2013 SelectedWorks

Uranian Moon Investigation With “Hitchhiker” Small Spacecraft, Jeremy Straub, Tyler Hill, Josh Berk, Nick Long

Jeremy Straub

This poster presents a mission concept for exploring the Uranian moon system utilizing two 6-U (30 cm x 20 cm x 10 cm, 8 kg) CubeSat spacecraft which will be deployed from and relay their communications to Earth through a primary spacecraft. This primary spacecraft, part of the Gap- Based Expanding Outer Region Geophysical Explorer (GEORGE) Mission, will initially work in concert with the 6-U CubeSats to create a gravity map of Uranus. Once this is completed, the spacecraft will re-dock so that the primary craft can move the two 6-U CubeSats to their orbit around Miranda to perform imaging ...


Hilbert Space Theory And Applications In Basic Quantum Mechanics, Matthew Gagne 2013 California Polytechnic State University

Hilbert Space Theory And Applications In Basic Quantum Mechanics, Matthew Gagne

Mathematics

We explore the basic mathematical physics of quantum mechanics. Our primary focus will be on Hilbert space theory and applications as well as the theory of linear operators on Hilbert space. We show how Hermitian operators are used to represent quantum observables and investigate the spectrum of various linear operators. We discuss deviation and uncertainty and briefly suggest how symmetry and representations are involved in quantum theory.
