Constraining the origin and influence of andesite in the Purico ignimbrite, N. Chile

Creator:: Lapinski, Sarah L.
Abstract:: A feature of large continental magmatic systems is voluminous dacite ignimbrites erupted from upper crustal magma reservoirs. In the Altiplano Puna Volcanic Complex (APVC) of the Central Andes, a major ignimbrite and caldera plateau, magma systems are found to be long-lived and remarkably homogeneous requiring that they be maintained by...

Exploring Links between Circadian Rhythms and Healthy Aging

Creator:: Mattison, Braden J.
Abstract:: Circadian rhythms are the daily oscillations in multiple organism functions, from clock gene expression to behavior. Lost or irregular rhythms lead to health problems later in life including nervous system disorders, abnormal sleep/activity cycles, diabetes and obesity. However, it is not known whether strengthening the expression of clock genes throughout...

Achilles Assistance Device as a Passive Ankle Foot Orthosis for Achilles Tendon Injuries

Creator:: Gonnerman, Evan J.
Abstract:: An Achilles tendon injury can be devastating. Surgical methods to bring the muscle to full strength are not always available. Proposed is an ankle foot orthosis (AFO) that is entirely passive (does not add energy to the system) and uses the mechanical advantages provided by the walking gait of a...

Systematic review of residual toxicity studies of pesticides to bees and comparison to language on pesticide labels using data from residual toxicity studies and USEPA published values

Creator:: Swanson, Leah
Abstract:: BACKGROUND. Residues of pesticides on crops can result in mortality to foraging bees. The likelihood of mortality can be mitigated by applying pesticides in the evening so that their residues dissipate by the following morning when bees resume foraging. The dissipation rates of different pesticides, or their residual toxicity, is...

Modification of Teleost Visual Feeding Range Model for Cuttlefish: A Visual-Systems Comparison

Creator:: Ebel, Rebekah E.
Abstract:: With human activity causing increases in turbidity in coastal marine waters, it is of economic and ecological importance to understand how this increase will affect organisms living in these areas. At most risk may be predators, such as many teleosts and cephalopods, reliant on vision to detect and capture prey....

Sonification as a pathway to knowledge

Creator:: Fitch, Russell Alan
Abstract:: This paper explores the use of sonification, the conversion of data into sound, to convey the significance of SARS-COV-2 and its global impact. It emphasizes sonification as a valuable tool for making complex data accessible, particularly in high school education. Sonification, an interdisciplinary field, leverages the human auditory system's pattern...
