The Model of Motivational Dynamics (MMD; Skinner and Pitzer, 2012) infers that peers influence behavioral engagement levels, which in turn is linked to coping and resilience. Scholars, however, are yet to test the MMD among an athletic population. The purpose of this paper was to assess an a priori model that included key constructs from the MMD, such as resistance to peer influence, behavioral...

Free acidity of aqueous solutions was initially defined in 1909 by Søren Peter Lauritz Sørensen as pH = −lgcH+ (c/mol·dm−3 or m/mol·kg−1 of the free hydrogen ions in solution, H+) soon (1910) was changed to pH = paH+ = −lgaH+, integrating the new concepts of activity, ai and activity coefficient γi, for the ionic species i under concern, H+ in this case; it is ai = −lg(miγi). Since individual i...

This paper documents the technology developed during the creation of the PR2 Remote Lab and the process of using it for shared development for Learning from Demonstration. Remote labs enable a larger and more diverse group of researchers to participate directly in state-ofthe-art robotics research and will improve the reproducibilS. Osentoski ( ) · B.

Solutions of iron(III) nitrate nonahydrate (INN) in ethanol and 1-propanol are interesting starting materials for producing iron oxide nanoparticles by spray flame synthesis. For the design these processes, it is important to have information on solid-liquid equilibria (SLE) solutions. As corresponding data were not available literature, we studied SLE solutions INN experimentally at temperatur...

T h r e s h e r E d i t o r i a l S t a f f A Faculty Committee on Undergraduate Teaching has been c r e a t e d and charged with "promoting excellence in undergraduate teaching by any appropriate means," President Kenneth S. Pitzer announced last week. Chairman of the committee is Ronald Sass, Master of Hanszen College. The committee was formed to fulfill the conditions of a g i f t of $500,00...

Air is one of the most important substances used in industrial and technological applications. Applications air require a consistent set reliable data on its thermodynamic thermophysical properties. Over last few decades, researchers have developed number empirical theoretical models for correlation prediction properties pure fluids mixtures. The ideal gas Equation State (EoS) property calculat...

The analogy between the restricted primitive model and capacitor circuits, originally described decades ago for Mean Spherical Approximation, is explored to demonstrate its transferability in linearized electrolyte theories. On this basis, we offer an explanation of why treating salt diameter as a free adjustable parameter blurs differences theories calculation mean ionic activity coefficients....
