Identification Of Bacterial Species Composition And Diversity Of Chicken Breast Meat During Processing., Lizzie Raquel Zaldivar

Theses and Dissertations

Understanding the bacterial profile of chicken during processing is essential to identify spoilage-related bacteria. Using advanced methods like Oxford Nanopore sequencing, specific bacterial species on chicken meat can be identified. This study aimed to characterize bacterial composition and diversity on chicken breast during processing. Results showed a reduction in aerobic bacteria, E. coli, coliform, and lactic acid bacteria counts. However, three thermophilic bacteria, Anoxybacillus contaminants, Neobacillus thermocopriae, and Anoxybacillus flavithermus, dominated across processing steps. Notably, Pseudomonas species were undetected by conventional plating but identified via Nanopore sequencing, highlighting the need for molecular detection methods. Although antimicrobial interventions significantly reduced bacterial …

Theses and Dissertations

In 2014, a virulent clonal group of Aeromonas hydrophila (VAH) was the predominant disease impacting the east Mississippi (EMS) commercial catfish industry. The EMS aquatic ambulatory service observed an area not prone to VAH outbreaks. In addition, frequent underestimations of the scope and economic impact of the EMS catfish industry and its diseases warranted a descriptive effort. Therefore, the EMS catfish industry, its economic impact, the diseases of this region and their economic impact were described. Further, differences in water and geological chemistry of the area not prone to VAH outbreaks, and the sensitivity of VAH and Edwardsiella ictaluri to …

Invasive Bigheaded Carp Distribution Patterns In Oxbow Lakes Of The Lower Mississippi Alluvial Valley, Michaela Ann Palmieri

Theses and Dissertations

Large populations of Silver Carp (Hypophthalmichthys molitrix) and Bighead Carp (H. nobilis), collectively called bigheaded carps, may have significant impacts where they are invasive. In the Lower Mississippi Alluvial Valley (LMAV), bigheaded carps have been documented in major rivers; however, knowledge of their distribution in oxbow lakes is lacking. Species distribution models are tools that can be used to estimate species distribution with presence data and environmental variables. As a cost-effective alternative to onsite sampling, I administered a questionnaire to biologists to inventory bigheaded carp presence and obtained environmental data from existing datasets. I used Maximum Entropy (Maxent) to illustrate …

Investigations Of Guayule Resin As A Wood Protectant, Queen Aguma

Theses and Dissertations

Wood products are subject to deterioration by numerous processes, as a biological material. Today, a significant area of preservative development is the utilization of existing plant residues that have water-repelling, antibacterial, antifungal, and insecticidal properties as components of wood protectants. Parthenium argentatum, known as guayule (wy-oo-lee), is a promising wood protectant due to its resin. However, the resin's complicated chemical, physical, and solvent-resistant properties make it difficult to use. The primary goal of this study was to eliminate the use of any solvent and rely on thermal modification only to fractionate usable compounds from guayule resin. Utilizing heated dialysis and …

Aboard The Giant Clam: Ramon Muzones's Maritime Historicization Of The Nation, Winton Lou G. Ynion

Kritika Kultura

Philippine literature scholarship is currently interested in decentering the discourse of nation-building from the capital to the periphery, but least often is attention given to the very geography that makes these communities marginalized. Habitually, multiculturalism and multilingualism have been convenient explanations for why it is difficult for the Philippines to come up with a “national literature” and a paradigm for imagining a nation. This essay centers on this neglected aspect, casting a novel written by a marginalized author in a vernacular language – the Margosatubig (1946) by Ramon Muzones. Three prime objectives guided the navigation of this paper: (1) to …

Site 152: A Small Settlement From The Bronze And Iron Ages In Ramot Menashe (With Contributions By Miriam Pines, Inbar Ktalav) (Hebrew; English Summary), Ron Beeri

'Atiqot

In a trial excavation conducted at Site 152 four occupation strata were discovered, dating to the Intermediate Bronze Age, Middle Bronze Age II, Late Bronze Age I and Iron Age I. A water channel, dating to the Hellenistic period or later, was also found. The finds included pottery, flint tools, animal bones and mollusks. This area appears to have been settled in almost all historical periods due to its proximity to water streams and alluvial soils.

A Byzantine-Period Monastery At Ḥura, Daniel Varga, Rina Talgam

'Atiqot

A building identified as a monastery, probably associated with the nearby Byzantine settlement at Ḥorbat Ḥur, was paved with four mosaic pavements containing four Greek inscriptions and one bilingual inscription in Greek and local Syriac. The inscription in the prayer hall indicates that the building was a monastery, probably founded in 575 CE. The monastery’s cemetery, located to its southwest, was well-preserved including four sealed graves of adult males, possibly monks. The mosaic art in the monastery deviates from the period’s trends, depicting figurative images and implicit crosses. This, and the location of the monastery, suggest that the monastery served …

The Effect Of Dha On Myo-Inositol Levels In Lymphoblasts Derived From Patients With Bipolar Disorder, Katherine Pierre

Honors Theses

Bipolar disorder is a mood disorder that is characterized by recurring episodes of mania and depression. Bipolar I disorder is accompanied by severe episodes of mania and depression, while bipolar II disorder is characterized by a milder form of mania. It has been hypothesized that currently approved treatments for this disorder, lithium and valproic acid, exert their therapeutic effect by decreasing myo-inositol levels intracellularly. However, these treatments may lead to undesired side effects, creating a need for safer treatments. Omega-3 fatty acids are polyunsaturated fats that have been shown to be effective in relieving symptoms of bipolar disorder.
