Distribution And Abundance Of Soft-Sediment Intertidal Polychaetes, Hassan Muftah Howege
Distribution And Abundance Of Soft-Sediment Intertidal Polychaetes, Hassan Muftah Howege
University of the Pacific Theses and Dissertations
Polychaetes are important components of the intertidal sandflat community in Lawson’s Flat, Dillon Beach, California. Little is known about the factors that control the relative abundance of these species. In view of the extensive evidence of the importance of interactions between component species in intertidal communities it is of interest to obtain information that would facilitate future experimental work of such interactions. This study documents seasonal changes in the abundance of the polychaete component of the intertidal community. Attention is directed at possible factors that might affect seasonal changes in distribution. A major finding is that certain herbivorous polychaetes exhibit …

Video Tape : An Old-New Instructional Aid In The Physics Laboratory, Fanny Mercedes Torres Holguin
University of the Pacific Theses and Dissertations
My objective is to use the video-tape as another medium -- along with overhead projector, textbooks, guides of apprenticeship, pictures, lab equipment and suggestions from the programs and new trends in physics teaching -- being used to supplement our efforts in trying to reach more and more of our students The use of audiovisual media, and generally speaking the use of technology in education, can be constructive or destructive, can e very powerful in developing "human beings" or "robots", can increase the rate of apprenticeship, or can produce an educational catastrophe. However, it will heavily depend on the the professor, …
Interactive Pace Approach To Learning In Physics : Method And Materials, Mario Amézquita
Interactive Pace Approach To Learning In Physics : Method And Materials, Mario Amézquita
University of the Pacific Theses and Dissertations
This study has the following general objectives: first, to present in detail the techniques that the author has developed and used in designed the course and the final materials produced for am introductory physics course in Mechanics; second, to state and examine the important blended ingredients used to get a new strategy for teaching-learning in which and individualized pace together with a group interaction is used; third, to analyze a combination of structural and operational course where concept, structure formation, and problem solving are emphasized.
Kinetics And Stoichiometry Of The Aquation Reaction Of Pentaaquomonobromomethylchromium (Iii) Perchlorate, Janice Imada Byington
Kinetics And Stoichiometry Of The Aquation Reaction Of Pentaaquomonobromomethylchromium (Iii) Perchlorate, Janice Imada Byington
University of the Pacific Theses and Dissertations
The purpose of this thesis was to determine the kinetics and stoichiometry for the aquation of the pentaaquomonobromonmethylchromium(III) complex. The complex was prepared by the reduction of dibromomethane by chromium(II). The products of aquation, in the absence of oxygen, were found to be hexaaquachromium(III), methanol, and bromide. The balanced net ionic reaction can be written: 2H2O + (H2O)5CrCH2Br2+ → (H2O)6Cr3+ + CH3OH + Br-
Group Of Point Transformations Of Time Dependent Harmonic Oscillators, Jose Ricardo Bernal
Group Of Point Transformations Of Time Dependent Harmonic Oscillators, Jose Ricardo Bernal
University of the Pacific Theses and Dissertations
In general, a physical system has invariant quantities which are very often related to its symmetry and to the invariance of the equation that describe it. A detailed study of the invariance property of the differential equation will be helpful in understanding this relation.
The work is concerned with a preliminary investigation of the Lie-group which leaves invariant the Newtonian and Lagrangian equation of motion for a one-dimensional harmonic oscillator. A brief review of Ehrenfest's adiabatic principle and the later treatments on exact and adiabatic invariants will be presented.
Some Applications Of Lie Transformation Groups To Classical Hamiltonian Dynamics, Donald Robert Peterson
Some Applications Of Lie Transformation Groups To Classical Hamiltonian Dynamics, Donald Robert Peterson
University of the Pacific Theses and Dissertations
Recent work has established that a group theoretical viewpoint of completely integrable dynamical systems with N degrees of freedom yields an algorithm that provides new information concerning the symmetry transformation group structure of this class of dynamical systems. The work presented here rests heavily on the results presented in reference and it is recommended that the reader consult this reference for a more rigorous discussion of the results given in this thesis.
