Department of Animal Science: Dissertations, Theses, and Student Research

Pregnancy to artificial insemination and late gestation fetal programming of the next calf crop are central to genetic development, reproductive longevity, calf crop productivity, and efficiency of cow/calf ranching. The purposes of this research are to find methods to improve pregnancy rate to artificial insemination, the growth and reproductive health of pregnant heifers, and the productivity of their offspring. In the first of four studies we found that extending the period of progesterone administration in an estrus synchronization protocol did not significantly hasten estrus response or increase pregnancy rate to artificial insemination, but timing of estrus within the melengestrol acetate …

Compound Marine Cold Spells And Hypoxic Events In A Nearshore Upwelling System, Ryan K. Walter, Michael Dalsin, Piero L.F. Mazzini, Cassia Pianca

Physics

Prolonged periods of extreme warm and cold seawater temperature anomalies, known as marine heatwaves (MHWs) and marine cold spells (MCSs), respectively, can have significant impacts on coastal marine ecosystems. Prior research has examined the co-occurrence of multiple extremes [low dissolved oxygen (DO) and/or low pH] during MHWs, with the impact of these compound events potentially exceeding that of a single stressor due to synergistic effects. However, we are not aware of any studies that have examined compound extreme events during MCSs, despite the ecosystem implications. Along Eastern Boundary Current Upwelling Systems (EBUS), strong-wind driven upwelling has led to …

Nonlocal Frameworks For Differential Equations--Analysis And Numerical Investigations, Layla Montemayor

Honors Program: Senior Projects (Public)

Systems of differential equations have been employed successfully in nearly every scientific field, including natural phenomena, finance, A.I. and machine learning. In a classical set up, a differentiable equation will be associated with a number of initial conditions that will help determine a unique solution to the system. The setting of classical differential equations requires assumptions on the regularity or smoothness of the input functions. Thus, we cannot produce with classical differential equations solutions which are irregular or even have discontinuities.

To overcome some of these challenges brought up by investigations of irregular or singular behavior, different formulations of nonlocal …

Soil Moisture Profile Estimation By Combining P-Band Sar Polarimetry With Hydrological And Multi-Layer Scattering Models, Anke Fluhrer, Thomas Jagdhuber, Carsten Montzka, Maike Schumacher, Hamed Alemohammad, Alireza Tabatabaeenejad, Harald Kunstmann, Dara Entekhabi

Geography

An approach for estimating vertically continuous soil moisture profiles under varying vegetation covers by combining remote sensing with soil (hydrological) modeling is proposed. The approach uses decomposed soil scattering components, after the removal of the vegetation scattering components from fully polarimetric P-band SAR observations. By comparing these with hydrological simulations, soil moisture profiles from the soil surface until a soil depth of 30 cm (assumed average P-band penetration depth) are estimated. Here, the hydrological model HYDRUS-1D, as a representative of any soil hydrological model, is employed to simulate an ensemble of realistic soil moisture profiles, which are used for a …

The Effect Of Crime On Mental Health In South Africa, Magda Tsaneva, Lauren-Kate Laplante

Economics

This paper examines the impact of district-level crime rates in South Africa on individual depression symptoms. We use panel data from the National Income Dynamics Survey collected between 2008 and 2014 and estimate an individual fixed effects regression model, thus controlling for characteristics of the individual's environment that could affect crime and mental health. We find that an increase of one standard deviation in property (violent) crime is associated with a 7.2 (8.7) percentage point increase in the probability of depression symptoms. Analysis of potential mechanisms suggests that indirect exposure to crime likely affects mental health by increasing stress rather …
