There is significant interest in harnessing the biosynthetic capacities of photosynthetic diatom microalgae for the production of unique bioinspired nanomaterials. Specifically, this research focuses on understanding the photoluminescent properties of diatom biosilica and β-chitin nanofiber production in diatoms. Diatoms are single-celled microalgae that possess intricately patterned biosilica shells called, frustules....
Statistical hypothesis testing has been widely criticized by ecologists in recent
years. I review some of the more persistent criticisms of P values and argue that most stem
from misunderstandings or incorrect interpretations, rather than from intrinsic shortcomings
of the P value. I show that P values are intimately linked...
The stability of 1 3-bis(2-chloroethyl)-1-nitrosourea
(NSC 409962)(BCNU) was investigated in several buffered
aqueous media, in mixed solvent and in nonaqueous solvent
systems, and in the presence of several electrolytes and
nonelectrolytes. The degradation rate constant of BCNU in
these systems was calculated from the parameters of the
linear regression of...
In an attempt to provide a practical means to measure the information
processing capacity of a real-time digital processing system a
theoretical framework, the Real-Time Schemata, whose basis is a
schematic description and a measure of "useful information," is presented.
The description applies to processes that would typically be
implemented...
Sequential machines uniquely determine directed graphs. A path in a sequential machine may be specified by a starting state and an input sequence. A uniform Hamiltonian touring sequence (UHTS) is an input sequence that specifies a Hamiltonian path regardless of the starting state. We present a polynomial time algorithm that...
The purpose of this study was to determine if parents of students
could improve the motor performance of their moderately and severely
mentally retarded children through the implementation of the
Data-Based Gymnasium (DBG) Instructional Model as a supplement to the
school program. The DBG Instructional Model is an individualized
system...
The field of accounting has experienced dramatic changes in the past 20 years. Advances in technology and workplace requirements have changed the responsibilities in the accounting position of a historical recorder to a functioning manager within the organization. The curriculum used by accounting instructors has not changed or kept pace...
