Effective Methods of Constituency Service in Oregon State
One would think that casework is the most effective method to reach constituents, however, that was not the case with this research about the Oregon State Legislature. Out of the 90 State Senators and House Representatives, there was a total of 50 surveys conducted and four interviews. The purpose of this research was to determine between casework, outreach and providing information, which method is deemed most effective within the Oregon Legislature when it comes to constituency service. Calculations show that third method, providing information, was the most effective with a solid 63%. These results shows that our legislator still lack in efforts with the other two main methods. There are certainly room for improvement when it comes to bettering the communication between constituents and legislators, even at the local level
Simple Combined Model for Nonlinear Excitations in DNA
We propose a new simple model for DNA denaturation bases on the pendulum
model of Englander\cite{A1} and the microscopic model of Peyrard {\it et
al.},\cite{A3} so called "combined model". The main parameters of our model
are: the coupling constant along each strand, the mean stretching
of the hydrogen bonds, the ratio of the damping constant and driven force
. We show that both the length of unpaired bases and the velocity
of kinks depend on not only the coupling constant but also the
temperature . Our results are in good agreement with previous works.Comment: 6 pages, 10 figures, submitted to Phys. Rev.
Effect of Dipolar Interaction in Molecular Crystals
We investigate in this paper the ground state and the nature of the
transition from an orientational ordered phase at low temperature to the
disordered state at high temperature in a molecular crystal. Our model is a
Potts model which takes into account the exchange interaction between
nearest-neighbor molecules and a dipolar interaction between molecular axes in
three dimensions. The dipolar interaction is characterized by two parameters:
its amplitude and the cutoff distance . If the molecular axis at a
lattice site has three orientations, say the , or axes, then when
D=0, the system is equivalent to the 3-state Potts model: the transition to the
disordered phase is known to be of first order. When , the
ground-state configuration is shown to be composed of two independent
interpenetrating layered subsystems which form a sandwich whose periodicity
depends on and . We show by extensive Monte Carlo simulation with a
histogram method that the phase transition remains of first order at relatively
large values of .Comment: 6 pages, 7 figure
