Purpose of the Study
The purpose of this study was to investigate the relationships
between modern and traditional schools and children's self-concepts.
In order to do this, it was necessary to describe and define the
phenomenon "self-concept" as used in education and to describe what the
author meant by modern...
Coastal multi-hazards, i.e., earthquakes followed by tsunamis, induce severe damage to coastal infrastructure. The multi-hazards can cause soil liquefaction, which is one of the major concerns for evaluating sediments transport potential and structure failure mechanisms. The objectives for this work is threefold. First, to build and validate a soil numerical...
The problems facing our nation's public schools today cannot
be divorced from our enthusiasm for technology and the positive
relationship we believe it shares with our perception of progress.
Based on the second law of thermodynamics, the law of entropy,
author Jeremy Rifkin argues that the development of increasingly
"efficient"...
Toxoflavin, a toxic secondary metabolite produced by a variety of bacteria, has been implicated as a causative agent in food poisoning and a virulence factor in phytopathogenic bacteria. This toxin is produced by the tox operon in Burkholderia glumae, in which the encoded protein, ToxD, was previously characterized as essential...
Natural products have long been an important source of resources for humans. Many of these compounds possess unique chemical structures and potent biological properties. By targeting natural products with specific chemical properties, we can gain a better understanding of the roles these compounds play in the environment and their interactions...
Cyanobacteria represent an underexploited source of bioactive natural products of interest to the pharmaceutical industry. Lack of development of these compounds as drug leads is due mainly to myriad practical problems with the producing strains including long doubling times, genetic intractability, and low compound yields. Previous attempts at heterologous expression...
This study utilizes differential scanning calorimetry (DSC) to characterize the thermodynamics, kinetics and crystallization b processes of a new Pt₅₇.₃Cu₁₄.₆Ni₅.₃P₂₂.₈ bulk metallic glass forming alloy. The heat capacity of the alloy is measured for the crystalline, glassy, and supercooled liquid phases. This data is used to obtain thermodynamic driving forces...
Two different doping techniques, oxygen intercalation and Mg cation
substitution, were investigated in thin film p-type CuScO₂, a wide band gap
semiconductor with the delafossite structure. Films rf-sputtered onto amorphous SiO₂
substrates were polycrystalline after post-deposition annealing. X-ray diffraction was
used to determine that the films are predominantly polycrystalline 3R...
