People cannot perform at their best unless they are healthy and well. A key behavior in attaining and maintaining a high state of health and wellness is physical activity. Regular physical activity participation is widely known to provide numerous physical, psychological, and social benefits. In spite of this, very few...
Several studies in recent years have demonstrated that upper-division students struggle with the
mathematics of thermodynamics. This paper presents a task analysis based on several expert attempts
to solve a challenging mathematics problem in thermodynamics. The purpose of this paper is twofold.
First, we highlight the importance of cognitive task...
[This paper is part of the Focused Collection on Upper Division Physics Courses.] The formalism of quantum mechanics includes a rich collection of representations for describing quantum systems, including functions, graphs, matrices, histograms of probabilities, and Dirac notation. The varied features of these representations affect how computations are performed. For...
The yields of over 200 projectile-like fragments (PLFs) and target-like fragments (TLFs) from the interaction of (E[subscript]c.m.=450 MeV) Xe¹³⁶ with a thick target of Pb²⁰⁸ were measured using Gammasphere and off-line γ-ray spectroscopy, giving a comprehensive picture of the production cross sections in this reaction. The measured yields were compared...
We present double-differential measurements of antineutrino charged-current quasielastic scattering in the MINERvA detector. This study improves on a previous single-differential measurement by using updated reconstruction algorithms and interaction models and provides a complete description of observed muon kinematics in the form of a double-differential cross section with respect to muon...
"After a brief description of the setting of the Yaquina Estuary, estuarine dynamics and classification, and estuarine chemistry are presented. Then, temperature-salinity relations are reviewed using the Rattray-Officer model in simulating variable distributions reported by Callaway and Specht (1982) and Callaway (1991). Finally, the numerical models DynHyd and WASP are...
This report discusses data collected in the Yaquina Estuary from July 1976 through December 1977 at 6-8 week intervals. Also summarized are recording salinometer, runoff and precipitation data from September 1967 through July 1968. Station names and locations for the 76-77 field data are shown in Figure 1. Figure 2...
Restoration to achieve Stage 0 is a valley-scale, process-based (hydrologic, geologic and biological) approach that aims to reestablish stream depositional environments to maximize longitudinal, lateral, and vertical connectivity at base flows and facilitate development of dynamic, self-formed and self-sustaining wetland-stream complexes. The term Stage 0 originally described complex multi-channel conditions...
The purpose of this research was to determine the common
professional training needs, proficiency and managerial requirements
of Oregon community college physical education instructors. The
respondents in this study were instructors who teach physical education
activity courses PE 180 - 185 - 190 in Oregon community colleges.
Four major tasks...
