Investigation of Homogeneous Degradation in Shape Memory Polyurethane Foams used in Embolic Applications
Get PDFShape Memory Polymers (SMPs) are a type of smart material that can transition from a deformed shape back to a preset shape when prompted by a stimulus such as a temperature change. SMPs have been used in a broad range of medical applications including blood vessel occlusion and aneurysm filling. The SMPs can be crimped to a compact, maneuverable secondary conformation for ease of placement, then actuated using the ambient body temperature and surrounding blood to expand back into its primary shape to fill a vascular region. Two types of SMPs are currently used in FDA-cleared medical devices and have been characterized via in vivo and in vitro testing. However, because tissue grows throughout the SMP after in vivo implantation, it is often difficult to accurately measure the amount of degradation of these SMPs. By measuring mass loss gravimetrically through in vitro studies and correlating them with digital microscopy and histological imaging at key degradation time points, we can help bridge the gap between the in vivo histological imaging of the degradation and the quantitative mass loss measured gravimetrically. This will also set the groundwork to create a calibration curve to quantify the amount of degradation seen in vivo
Bacterial Early Seedling Decline Disease of Peanuts
Get PDFPeanuts (Arachis hypogaea L.) are legumes that are grown in tropical and subtropical regions of the world and serve as an important source of oil and protein. In Texas, peanuts are produced in nine of the 12 agricultural districts of the state, accounting for approximately 4.5 percent of the state's annual revenue from agriculture (Texas A&M AgriLife Extension Annual Increment Report, 2020) and approximately 12.4 percent of total U.S. peanut production (USDA-NASS, 2019)

Fueling the mind, feeding the world: Decision making ��� Lifelong learning (DM06)
Get PDFFall 2024 version. Created at Texas A&M University as part of a grant sponsored by the USDA.
For additional information, visit the Texas A&M University Science Communications Lab at https://scicomm.tamu.edu/.This packet contains instructional materials and online modules prepared for Fueling the mind, feeding the world: Decision making ��� Lifelong learning (DM06). It includes curriculum, PowerPoint slides, activities, handouts, grading considerations, and notes for instructors. These materials were created as part of the USDA Grant entitled "Fueling the Mind, Feeding the World: Enhancing Communication and Decision-Making Skills of Secondary Agricultural Education Students."
MODULE OVERVIEW: Learning does not���and should not���end when students graduate from high school. Lifelong learning should continue for personal and professional topics, and positive self-talk can help individuals keep a growth-oriented mindset. After deciding what to learn, lifelong learners find resources, set goals, and evaluate the finished product.Secondary Education, Two-Year Postsecondary Education, and Agriculture in the K-12 Classroom (SPECA) Challenge Grants Program no. 2019-38414-30265 and Hatch Project No. TEX09825 from the USDA National Institute of Food and Agriculture
