Temperature-Dependent Macrophage Activity In Rainbow Trout, Danica McGrevey 2021 University of Arkansas, Fayetteville

Temperature-Dependent Macrophage Activity In Rainbow Trout, Danica Mcgrevey

Biological Sciences Undergraduate Honors Theses

Fever is an essential component of the immune response. Fever enhances immune responses as well as creates an environment in which the body has advantages over pathogens. Macrophages are often the first cells that come in contact with pathogens, as they reside in tissues. They are important for their engulfment of pathogens that results in the digestion of the pathogen, but they also produce nitric oxide and cytokines that contribute to immune response in a variety of ways, including initiating adaptive immunity and directing the production and activity of other immune cells. We were curious about macrophages from other temperature ...

Impulse Vaccination Model For The Control Of Devil Facial Tumor Disease, Zachary Bobbitt, Timothy Comar, Megan O. Powell, Catherine Roberts, Nicholas Schneider, Teagen Smith

Spora: A Journal of Biomathematics

Devil facial tumor disease (DFTD) is a cancer that affects Tasmanian devils and that has caused the devil population to grossly decline since 1996. We present an SEIVR model to explore if recent advances in DFTD vaccines can help the wild population recover. Considering both and bi-annual impulse of vaccinating wild devils through food drops and introducing vaccinated captive-bred devils into the population, we explore the vaccine efficacy, percent of healthy devils receiving the vaccine, and years of campaign necessary for the devil population to have a long-term recovery. Based on our initial parameter estimations, we find a stable population ...

Prevalence Of Snake Fungal Disease Caused By Ophidiomyces Ophiodiicola In East Texas, Alan Lizarraga 2020 University of Texas at Tyler

Prevalence Of Snake Fungal Disease Caused By Ophidiomyces Ophiodiicola In East Texas, Alan Lizarraga

Biology Theses

Fungal pathogens and resultant disease are credited with the decline of many species across all branches of the tree of life. Fungal diseases such as Snake Fungal Disease (SFD), primarily caused by the fungus Ophidiomyces ophiodiicola (Oo), have been strongly associated with the cause of the decrease/disappearance of many snake populations in North America. To date SFD in the wild has been described as far southwest as central Louisiana. Due to similar conditions and the proximity of East Texas to central Louisiana, a survey of local snake populations provided crucial information about the spread and presence of this emerging ...

Has Covid-19 Impacted Price-Weight Relationships And Value Of Gain?, Elliott James Dennis 2020 University of Nebraska-Lincoln

Has Covid-19 Impacted Price-Weight Relationships And Value Of Gain?, Elliott James Dennis

Extension Farm and Ranch Management

First paragraph:

In the beginning of COVID-19, much of the attention was focused on managing the redirection of meat product from food service to retail stores. This past month has keenly focused on packing plant closures due to COVID-19 cases among workers and how to manage the supply of fat cattle already ready for slaughter. Fat cattle available for slaughter either cannot get bids or bids are significantly below breakeven prices leaving feedlots with decisions to be made about marketing and placements. The April 2020 Cattle on Feed report (https://usda.library.cornell.edu/concern/publications/m326m174z) revealed March placement ...


Pre Covid-19 Market Conditions Persist & The Stocker Industry Can Dampen The Damage, Elliott James Dennis 2020 University of Nebraska - Lincoln

Pre Covid-19 Market Conditions Persist & The Stocker Industry Can Dampen The Damage, Elliott James Dennis

Extension Farm and Ranch Management

First paragraph:

The effects of COVID-19 on the livestock market are well known and felt. Some effects include depressed futures and cash prices, unusual basis patterns, decreased packer bids and sale barn volume, packing plant closures, consumer hording of meat products, and shifting food service products for retail consumption. All these effects occurred as market participants grappled with everchanging government and industry policy which reduced consumer demand and resulted in bottlenecks and increasing supply gluts upstream. Simultaneously reducing demand and increasing supply always cause prices to plummet, and in the case of COVID-19 very rapidly. Some segments of the market ...


Live Cattle Basis Due To Covid-19: Deviations And Convergence, Elliott James Dennis 2020 University of Nebraska - Lincoln

Live Cattle Basis Due To Covid-19: Deviations And Convergence, Elliott James Dennis

Extension Farm and Ranch Management

A Fundamental Review on Basis

Basis is defined as the cash minus futures. Cash market reflects today's supply conditions and price. Futures market reflects upcoming supply and demand conditions. If it is anticipated that there will be a period of increasing supplies, futures prices will decline to reflect that information. Likewise, periods of time with expected decreasing supplies, future prices are expected to increase.

Since cash and futures prices can move simultaneously, basis will fluctuate through time. In periods where basis becomes more positive (i.e. basis is said to be strengthening/narrowing) it implies that cash prices are ...
