The role of zinc nanoparticles in the initial events of olfaction, their characterization, preservation, and microenvironmental influence.
(2018-04-24)
Olfactory responses are intensely enhanced with the addition of endogenous and engineered primarily-elemental small zinc nanoparticles (ZnNPs). The endogenous ZnNPs have been found as proteon nucleating centers (PNCs) ...
The Roles of Acoustic and Visual Signals in the Reproductive Behavior of the Federally Threatened Pygmy Sculpin, Cottus paulus, (Cottidae)
(2009-07-02)
Animals use many modes of communication (i.e. tactile, visual, acoustic and chemical) for territory defense, resource defense, and/or courtship. These communication systems can be used singularly or combined together, such ...
Roles of an 'Inactive' Domain in Catalase-Peroxidase Catalysis: Modulation of Active Site Architecture and Function by Gene Duplication
(2006-12-15)
Within biological systems iron is a transition metal that allows access to the benefits of molecular oxygen as an oxidant. However, with these benefits come grave consequences if the reactions are not strictly controlled. ...
The Roles of Cytokinins and Cytokinin-N-Glucosides in Development and Gene Expression of Arabidopsis thaliana
(2020-07-02)
The phytohormone cytokinin (CK) was first discovered over sixty years ago, and the decades following have produced an enormous amount of data about the various roles CK plays in intracellular signaling, gene expression, ...
Roles of Large Loops in Catalytic Versatility of Catalase-Peroxidases: Significance of Peripheral Structures in Improvising Enzyme Functions
(2012-05-07)
Catalase-peroxidases are bifunctional enzymes that catalyze the removal of hydrogen peroxide by two distinct pathways (catalase and peroxidase). They are central to antibiotic resistance in Mycobacterium tuberculosis and ...
The Roles of Leadership in High Performing High Poverty Schools: A Case Study of Four Torchbearer Principals and Their Schools
(2013-03-21)
This study presents a comparative case study of four Torchbearer high performing-high poverty schools located in south Alabama. Using the underlying assumption that all children can learn and that principals are integral ...
The Roles of Touching and Massage Among Occupational Therapists and Teachers in Early Intervention Programs
(2008-12-15)
The purpose of this study was to determine what occupational therapists and teachers in early intervention programs know about touching and massage; their personal attitudes about touching and being touched; and their ...
Roles of Two Interhelical Insertions in Catalase-peroxidase Catalysis: Tracing the Impact of Peripheral Protein Structures on Heme Enzyme Function
(2005-08-15)
Monofunctional peroxidases and bifunctional catalase-peroxidases share almost superimposable active sites, yet peroxidases lack appreciable catalase activity. Moreover, catalase-peroxidases catalyze both catalase and ...
Roles, Relationships, and Power: The Patterns of Knowledge Co-Construction in an Online Educational Leadership Course
(2020-07-16)
Social interaction is an essential component of learning, but the online learning environment presents challenges to creating meaningful interactions (Palloff & Pratt, 2003; Simonsen, 2015). Researchers have long sought ...
Roll & Bank Estimation Using GPS/INS and Suspension Deflections
(2012-07-25)
This thesis presents three methods that provide and estimate of road bank by decoupling the vehicle roll due to dynamics and roll due road bank. Suspension deflection measurements were used to provide a measurement of the ...
Romantic Relationship Attachment and Identity Style as Predictors of Adolescent Interpersonal Competence: A Mediation Model
(2008-08-15)
Since interpersonal competence is such a significant predictor of a variety of important outcomes for adolescents, the central goal of the current study was to investigate the developmental factors of attachment style and ...
Romantic relationship investment and commitment: An expansion of the Investment Model conceptualization
(2015-12-08)
Objective: Rusbult (1980) postulated that the endowment of personal contributions to a
romantic relationship increases relationship commitment. This two-study project developed and
psychometrically tested a theoretical ...
Romantic Relationship Trajectories: A Qualitative Analysis of Young Adults Exposed to Marital Violence
(2016-08-05)
