Solvent Recovery for an Extraction Process
The solvent recovery project involves the recovery of a valuable solute, acetic acid, from a spend solvent stream generated in a laboratory extraction experiment. The majority of this project’s efforts center on the simulation of a ten-stage distillation column that will recover the acid. These simulation results will then be used to specify the ancillary process equipment needed for this distillation process
Diffusion versus linear ballistic accumulation: different models but the same conclusions about psychological processes?
Quantitative models for response time and accuracy are increasingly used as tools to draw conclusions about psychological processes. Here we investigate the extent to which these substantive conclusions depend on whether researchers use the Ratcliff diffusion model or the Linear Ballistic Accumulator model. Simulations show that the models agree on the effects of changes in the rate of information accumulation and changes in non-decision time, but that they disagree on the effects of changes in response caution. In fits to empirical data, however, the models tend to agree closely on the effects of an experimental manipulation of response caution. We discuss the implications of these conflicting results, concluding that real manipulations of caution map closely, but not perfectly to response caution in either model. Importantly, we conclude that inferences about psychological processes made from real data are unlikely to depend on the model that is used
Spin-lattice order in frustrated ZnCr2O4
Using synchrotron X-rays and neutron diffraction we disentangle spin-lattice
order in highly frustrated ZnCrO where magnetic chromium ions occupy
the vertices of regular tetrahedra. Upon cooling below 12.5 K the quandary of
anti-aligning spins surrounding the triangular faces of tetrahedra is resolved
by establishing weak interactions on each triangle through an intricate lattice
distortion. The resulting spin order is however, not simply a N\'{e}el state on
strong bonds. A complex co-planar spin structure indicates that antisymmetric
and/or further neighbor exchange interactions also play a role as ZnCrO
resolves conflicting magnetic interactions

Using a Flipped Classroom to Teach Evidence-Based Practice to Entry-Level Occupational Therapy Students
Constructivist teaching approaches rely on students to be active participants in their learning. A flipped classroom is a constructivist approach that requires the students to complete pre-learning activities outside of class. Thus, in class the students can practice and engage in team-based discussions and teacher guided learning. We delivered evidence-based practice (EBP) concepts to entry level occupational therapy (OT) students in a doctoral program using a constructivist approach, that included a flipped classroom model and reliance on team-based strategies. We used the Evidence Based Practice Confidence (EPIC) Scale to assess the change in students’ confidence in EBP. Students demonstrated statistically significant differences in their confidence for EBP after the course. Evaluation of the changes in EPIC Scale scores indicates that a flipped classroom and team-based activities are effective approaches to teach EBP for entry level OT doctoral students
Structural Anomalies at the Magnetic and Ferroelectric Transitions in (R=Tb, Dy, Ho)
Strong anomalies of the thermal expansion coefficients at the magnetic and
ferroelectric transitions have been detected in multiferroic . Their
correlation with anomalies of the specific heat and the dielectric constant is
discussed. The results provide evidence for the magnetic origin of the
ferroelectricity mediated by strong spin-lattice coupling in the compounds.
