Maintaining body weight in breeders is highly emphasized prior to first egg as to reach optimum peak production feeding increases dramatically to meet energy needs. Energy is supplied to the breeder in three forms carbohydrates (fast energy), protein (medium energy), and fat (slow energy). Carbohydrates are quickly used by the breeders, while protein is constantly being utilized by the breeder for growth and egg production, fat is stored and used lastly as the energy requirements …
Developing Anisotropic Soft Matter As Functional Materials To Interface With Biological Systems, Homa Ghaiedi
Developing Anisotropic Soft Matter As Functional Materials To Interface With Biological Systems, Homa Ghaiedi
Graduate Theses and Dissertations
Liquid crystals (LCs) constitute a subset of soft matter possessing hybrid characteristics from both liquid and crystalline phases. In this state, the center of masses remains uncorrelated similar to an isotropic phase, while the long axis of molecules aligns in parallel, resulting in molecules exhibiting orientational and positional order, either individually or concurrently. The directional alignment inherent in LCs arises from the asymmetrical shape and structure of the constituent molecules, causing a spontaneous self-assembly into ordered phases. This cooperative molecular behavior manifests distinctive optical features when subjected to cross polarizers. The remarkable sensitivity of LCs to external stimuli, including temperature, …

The Causes And Consequences Of Behavioral Plasticity In Anti-Predatory Defense And Mate Choice In Tropical Butterflies, Sushant Potdar
The Causes And Consequences Of Behavioral Plasticity In Anti-Predatory Defense And Mate Choice In Tropical Butterflies, Sushant Potdar
Graduate Theses and Dissertations
Behavioral plasticity, where individuals change their behaviors in response to varying environmental and social conditions, affects major evolutionary trajectories. But how individuals change these behaviors under certain social situations, and what the genetic causes and consequences of such behavioral changes are in response to social environments are yet to be fully understood. I address these questions in the context of anti-predatory behaviors (chapter 1), and mate choice (chapters 2, 3, 4) in tropical butterflies. In the context of anti-predatory behaviors, I found predator-specific behavioral changes in toxic Heliconius butterflies, suggesting variance in predation pressures and butterfly recognition of bird calls. …

Guaraní Sexuality And Contestations Over The Old Way Of Being, Robert Miles Berry
Guaraní Sexuality And Contestations Over The Old Way Of Being, Robert Miles Berry
Graduate Theses and Dissertations
The Jesuits in seventeenth century Guairá attempted to shift the sin of adultery and polygyny away from Guaraní men, and onto Guaraní women in their process of evangelization in Paraguay. The Jesuits did so because Guaraní men, as influential patriarchs within the missions, would revolt against the Jesuits or flee the Jesuit missions in response to Jesuit indoctrination that denounced the practice of polygyny. This is evident through two works of the Jesuit Antonio Ruiz de Montoya: one lexical, the Tesoro, and the other narrative, the Conquista. Montoya was directly involved in the founding and maintenance of the Guaraní missions, …
