Tn5 mutagenesis of apdA (for antibiotic production) and deletion of
gacA (for global antibiotic and cyanide) resulted in the same pleiotropic phenotype in
Pseudomonas fluorescens (i.e. production of an array of secondary metabolites
including the antibiotics pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol as
well as a tryptophan-side-chain oxidase, hydrogen cyanide, and an...
Inheritance from pre-existing mantle domains and fluid and melt contributions from active subduction together produce the geochemical signatures of mantle-derived arc basalts. In this context, this work evaluates the evolution of Cascadia mantle sources by documenting the isotopic and compositional characteristics of primitive basalts along a transect across the Eocene-Oligocene...
Many countries around the world are looking to tourism as a sustainable solution for economic development and many individuals seek business opportunities in the tourism industry. Researchers in the field of anthropology and other disciplines alike have recorded findings of the environmental, economic and cultural impacts of tourism development that...
There is a wealth of research on issues surrounding teacher burnout and school reform. The literature on burnout, however, does not provide information on system-based burnout prevention models. Comprehensive reform, although intended to improve schools as a whole, does not look at reform models developed as sources of teacher support....
The fusion reaction ²⁰⁸Pb (⁵⁰Ti, xn) ²⁵⁸⁻x Rf (x = 1-3) was studied to determine PCN (probability that the mononucleus system evolves to form a compound nucleus inside the fission saddle point) and to establish the value of Wsur (survival probability) for the given reaction experimentally. The fission excitation function...
Greenwashing is a relatively novel, diversely interpreted, and under-researched social phenomenon. Therefore, studying greenwashing concepts, methodological yardsticks, and the dynamic behind its pervasiveness provides an excellent opportunity to improve our understanding of it, refine our detection tools, and illuminate its influencing factors and impacts on society. This study aims to:...
This study investigated the effect of first aid instruction on
college students' attitudes toward safety. It evolved from previous
studies of the relationship between first aid and accidents in Canada
and the United Kingdom. These earlier studies were concerned with the
effect of first aid training on accident rates. The...
