Interesting rovibrational characteristics of two D_(3h) oblate symmetric top molecules were studied. Hamiltonian models for the fine rovibrational level structure of [1.1.1]propellane (propellane) were obtained for many low-lying modes. Ground state parameters (GSP) that are not exclusively K^(2n) dependent were obtained. Initially, the GSP were used in conjunction with density...

Interesting rovibrational characteristics of two D3h oblate symmetric
This investigation attempts to demonstrate that the development
of the early 20th century biological enterprise involved a striving for a
unifying theoretical perspective. A skeletal substantiation of this is
given by an overview of early 20th century biology in which some
biologists began recognizing a multiplicity of different orders of...
The purpose of this study was to understand how instruction in an introductory nonmajor astronomy course at Oregon State University affects how non-science majors view science and the scientific process. The study used research-based methods to design a reform-based lecture/lab course and implement it for students. Two top-level questions were...
Microfluidic devices have enabled lab-on-a-chip (LOC) systems that allow for complex sample analysis and preparation in a compact form factor. One technology that may benefit from a microfluidic approach and further miniaturization is flow cytometry. Flow cytometry is an analysis technique for enumerating and characterizing populations of cells; this is...
While hydrophobic surfaces coated with the poly[ethylene oxide]-poly[propylene oxide]-poly[ethylene oxide] (PEO-PPO-PEO) surfactant Pluronic® F108 are highly resistant to plasma protein adsorption, the antimicrobial peptide nisin has been observed to adsorb in multilayer quantities at such surfaces, and the PEO chains themselves suggested to inhibit nisin exchange by blood proteins. But...
Infections in hospitals account for over 100,000 deaths per year. These infections occur at the
hospital from complications following bacterial adhesion to intravenous catheters, coronary
stents and other implanted devices. Another common problem is protein adsorption to the
surface of the device and subsequent blood clotting. Methods for combating these...
The strained carbon ring, bicyclo[1.1.1]pentane, was synthesized by a reaction between
1-(phenylsulfanyl)bicyclo[1.1.1]pentane, prepared from propellane, and Raney nickel.
Infrared spectra were recorded at a resolution of 0.0015 cm-1, a resolution significantly
better than previous measurements, 0.06 cm-1. A single fundamental band was analyzed
to determine the ground state and excited...
Global increases in ultraviolet-B radiation (UVBR:290-
320 nm) resulting from decreases in stratospheric ozone
concentration have the potential to alter marine primary
production and affect global climate and marine trophic
dynamics. Effects of UVBR on phytoplankton carbon fixation
were determined from open ocean exposure studies conducted
off the coast of...
