One-dimensional numerical analysis of the transient thermal response of multilayer insulative systems

A one-dimensional numerical analysis of the transient thermal response of multilayer insulative systems has been developed. The analysis can determine the temperature distribution through a system consisting of from one to four layers, one of which can be an air gap. Concentrated heat sinks at any interface can be included. The computer program based on the analysis will determine the thickness of a specified layer that will satisfy a temperature limit criterion at any point in the insulative system. The program will also automatically calculate the thickness at several points on a vehicle and determine total system mass

The Powers of North Carolina’s Second Executive: Discovering if the Lieutenant Governor Should be Designated more Power under the Constitution

In the original 1776 North Carolina State Constitution, the executive branch of government was solely comprised of the Governor. It was not until 1868 that the Lieutenant Governor position, along with other executive offices, was added to the branch. The current NC State Constitution today was ratified in 1971 and outlines the powers of the Governor and Lieutenant Governor thoroughly. The designated constitutional powers of the NC Lieutenant Governor include serving as the President of the Senate with the ability to cast tie-breaking votes, serving on the State Board of Education, and most notably, succeeding the Governor upon the death, resignation, or removal from office. These powers are weak in the spectrum of NC government because ties in the Senate and Governor’s leaving office are rare. Additionally, it is important to note that in North Carolina, the Governor and Lieutenant Governor are elected separately and independent from each other, which can possibly result in the two offices representing different parties. I am going to argue that the office of the Lieutenant Governor should be delegated more constitutional powers rather than relying so heavily on the assignment of duties from the General Assembly and Governor. I will conduct research on the election style of the Lieutenant Governor, which additional powers (if any) should be designated to the Lieutenant Governor, and what are other States doing in terms of designating executive powers to their Governor and Lieutenant Governor

Chemical equilibrium of ablation materials including condensed species

Equilibrium is determined by finding chemical composition with minimum free energy. Method of steepest descent is applied to quadratic representation of free-energy surface. Solution is initiated by selecting arbitrary set of mole fractions, from which point on free-energy surface is computed

Effects of Craniofacial Structures on Mouse Palatal Closure In Vitro

Heads of Swiss-Webster mouse fetuses of four ages spanning days 12-13 of gestation, were partially dissected by removing the brain (B), tongue (T) and mandible (M) alone or in combination (BT, BM, BTM). Preparations were suspended in a gassed, circulating culture system such that palatal closure must take place against gravity. Closure occurred earlier than in vivo and required the posterior half of the mandible be intact and the tongue removed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68249/2/10.1177_00220345780570024401.pd

X ray imaging microscope for cancer research

The NASA technology employed during the Stanford MSFC LLNL Rocket X Ray Spectroheliograph flight established that doubly reflecting, normal incidence multilayer optics can be designed, fabricated, and used for high resolution x ray imaging of the Sun. Technology developed as part of the MSFC X Ray Microscope program, showed that high quality, high resolution multilayer x ray imaging microscopes are feasible. Using technology developed at Stanford University and at the DOE Lawrence Livermore National Laboratory (LLNL), Troy W. Barbee, Jr. has fabricated multilayer coatings with near theoretical reflectivities and perfect bandpass matching for a new rocket borne solar observatory, the Multi-Spectral Solar Telescope Array (MSSTA). Advanced Flow Polishing has provided multilayer mirror substrates with sub-angstrom (rms) smoothnesss for the astronomical x ray telescopes and x ray microscopes. The combination of these important technological advancements has paved the way for the development of a Water Window Imaging X Ray Microscope for cancer research

Scattering of 7^{7}Be and 8^{8}B and the astrophysical S17_{17} factor

Measurements of scattering of $^{7}$Be at 87 MeV on a melamine (C$_{3}$N$_{6}$H$_{6}$) target and of $^{8}$B at 95 MeV on C were performed. For $^{7}$Be the angular range was extended over previous measurements and monitoring of the intensity of the radioactive beam was improved. The measurements allowed us to check and improve the optical model potentials used in the incoming and outgoing channels for the analysis of existing data on the proton transfer reaction $^{14}$N($^{7}$Be,$^{8}$B)$^{13}$C. The resultslead to an updated determination of the asymptotic normalization coefficient for the virtual decay $^{8}$B $\to$ $^{7}$Be + $p$. We find a slightly larger value, $C_{tot}^{2}(^{8}B)=0.466\pm 0.047$ fm$^{-1}$, for the melamine target. This implies an astrophysical factor, $S_{17}(0)=18.0\pm 1.8$ eV$\cdot$b, for the solar neutrino generating reaction $^{7}$Be($p$,$\gamma$)$^{8}$B.Comment: 7 pages, 4 figure
