THE EFFECT OF HOLDING TIME OF WHOLE MARE BLOOD ON CONCENTRATION OF PROGESTERONE

The objective of this study was to evaluate if holding time had an effect on mare whole blood progesterone levels. This research was completed using 12 mares, with blood being collected on multiple cycles to get a total of 28 separate blood collections. At each collection 5 vials of blood were taken for different time treatments of 0, 12, 24, and 48 hours. The 0 hour was centrifuged within 30 mins of collection and the other 4 were refrigerated at 4℃ until the specific time treatment was finished. After they were centrifuged all the samples were stored in the freezer at -22℃ until they were transported to the lab. A total of 140 data points was analyzed for this research. On further analysis of the results, the conclusion is that there is no effect of time on concentration of progesterone in the whole blood of mares

Rye, triticale, and intermediate wheatgrass: Recent updates in research, plant breeding, and their common uses

This creative component (CC) provides a brief snapshot into three alternative small grain crops that provide viable alternatives to fill niche roles on farms looking for additional crops to include in their production system. These include, an ancient grain rye (Secale cereale L.), a man-made species Triticale (×Triticosecale Wittm. ex A. Camus) and a crop just beginning to be commercialized intermediate wheatgrass (Thiopyrium intermedium), with the first commercialized cultivar, Kernza™. The major areas covered in this CC includes the most recent updates on research, breeding and common uses for these three crops. These three crops rye, triticale and intermediate wheatgrass have multipurpose roles to fill on the farm including forage, fodder, grain and cover crop. On-going research is expanding and improving their economic viability along with their ability to excel on marginal soil and in unproductive areas on a farm

Carbon Mineralization in Fractured Basalt

The need to meet rising energy demands while mitigating climate change driven by associated CO2 emissions has motivated the development of geologic carbon storage systems. Until recently, most research has focused on sedimentary reservoirs that rely primarily on short-term solubility and physical trapping mechanisms, where CO2 can migrate if the structural integrity of the caprock or wellbore is compromised. This inherent leakage risk could be eliminated by leveraging the natural reactivity of basalt reservoirs, which are abundant in silicate minerals that dissolve rapidly under acidic conditions and can ultimately trap dissolved CO2 as solid carbonate minerals. Given the significant advantage of mineral trapping for long-term storage security, basalts may be the most readily deployable CO2 repositories in the near term. However, our fundamental understanding of the conditions under which this CO2 mineralization process occurs and its viability as a permanent carbon sequestration pathway remain limited. This dissertation highlights multiple series of high-pressure core flooding experiments and coupled reactive transport models designed to evaluate the effects of temperature, fluid chemistry, and flow regimes on basalt dissolution and CO2 trapping through carbonate precipitation. Results indicate that basalts can effectively mineralize CO2 at representative subsurface stress conditions, but mineralization predominantly occurred within buffered diffusion-limited zones (e.g. dead-end fractures) where reaction fronts have developed from competing geochemical gradients. Carbonate precipitation was highly localized on the reactive silicate minerals contributing key divalent cations and was significantly enhanced by elevated temperature and alkalinity. Complementary triaxial direct shear fracturing experiments with carbonate-rich shales revealed that spatial distributions of precipitates may be more significant than the total amount, as small volumes at critical fracture contact points can dramatically restrict flow. In combination, this work demonstrates how complex interactions between reservoir geochemistry and transport conditions drive the extent and location of carbon mineralization reactions in basalt fractures, which will inform selection of storage sites and injection schemes that optimize long-term CO2 trapping efficiency.PHDEnvironmental EngineeringUniversity of Michigan, Horace H.
