Equitable access to primary health care is vital to the overall health and development of a country. Since its independence in 1967, Tanzania has established a clear objective of achieving primary health care for all. Yet achieving the goal of health care for all is especially difficult considering Tanzania’s poverty...
Crystals are solid materials with periodic and symmetric molecular patterns. The structure of a crystalline solid determines its properties, making it essential to study its structures. From the principle of minimum energy, a crystal will choose a structure with the lowest free energy F = U – TS. At low...
Mixed anion compounds that form ZrCuSiAs-type crystal structures exhibit remarkable properties such as superconductivity at low temperatures,
hole conduction with optical transparency in the visible region, and exciton absorption at room temperature. In this thesis, properties of a selected group of materials out of the very large set of mixed...
The ability to focus light through strongly scattering materials is opening up exciting new avenues in many fields, such as optics, computer vision, biology, and medicine, which utilize light delivery and imaging techniques. Efficient, high resolution wavefront shaping and optimization methods are crucial to enabling this new capability.
In this...
The behavior of small atomics cluster largely depends on their geometry,
due to the high ratio of surface atoms to interior atoms. One interesting aspect
to study clusters centers around characterizing the transition behavior between
nite and bulk materials, where the ratio of surface atoms to interior atoms is
very...
This thesis presents the results of quantum-mechanical first principles calculations
of optical, electronic and mechanical properties of organic molecules and solids, which have
diverse potential applications such as photovoltaics, flexible electronics, and mechanical
catalysts with applications in force sensors and self-healing materials.
The electronic and optoelectronic properties of organic thin...
When the Affordable Care Act was passed in 2010, eligibility for Medicaid was expanded to include people whose income was less than 138% of the federal poverty level. In 2012, the Supreme Court ruled that states could choose whether to expand their Medicaid programs or not. The objective of this...
American Indians and Alaska Natives (AIAN) have more negative sexual and reproductive health outcomes than non-Hispanic whites. Little is known, however, about the factors that lead to sexual and reproductive health disparities for AIANs, including the role of sexual and reproductive health services (SRHS).
Logistic regression analyses were performed on...
As indicated by the title, this thesis generalizes the Main Inertia
Theorem of Ostrowski and Schneider [8]. The first three results
concern the formation of a polynomial function f(A, A*, H) so that
the existence of an hermitian H for which f(A, A*, H) is positive
definite is a necessary...
