Challenges In Model Development For Meat Composition Using Multipoint Nir Spectroscopy From At‐Line To In‐Line Monitoring, Yash Dixit, Maria Piedad Casado-Gavalda, R. Cama-Moncunill, Patrick J. Cullen, Carl Sullivan

Articles

This study evaluates the efficiency of multipoint near‐infrared spectroscopy (NIRS) to predict the fat and moisture content of minced beef samples both in at‐line and on‐line modes. Additionally, it aims at identifying the obstacles that can be encountered in the path of performing in‐line monitoring. Near‐infrared (NIR) reflectance spectra of minced beef samples were collected using an NIR spectrophotometer, employing a Fabry‐Perot interferometer. Partial least squares regression (PLSR) models based on reference values from proximate analysis yielded calibration coefficients of determination of 0.96 for both fat and moisture. For an independent batch of samples, fat was estimated with a prediction …

The Experience Of Qigong Among Women Cancer Survivors, Jennifer Sveund

Antioch University Dissertations & Theses

Research has shown that qigong can be beneficial for a variety of health related conditions; However, evidence suggests that in the United States, a lack of well designed clinical trials limits the efficacy of qigong in the context of cancer treatment. Research has indicated that careful consideration should be given to the design of randomized control trials using qigong due to the conflicting philosophical methodologies. In the United States, qigong has been under investigated, particularly lacking are qualitative inquiries into qigong use and cancer survivorship. This study is an interpretative phenomenological inquiry that sought to understand women’s experience of qigong …

From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins

Antioch University Dissertations & Theses

Plastics, the epitome of disposable culture, pose both a toxicological and a spiritual problem. This dissertation examines plastics at a molecular level using the discourse of endocrine disruption, and at a sociological level using the discourses of eco-theology and environmental justice. Adding to the literature on the adsorption of toxicants to plastic marine debris, I demonstrate that certain types of plastic -- those containing mercaptans, such as styrene butadiene block copolymer -- efficiently concentrate methyl mercury from seawater. Further, samples of polycarbonate contributed mercury to seawater. I propose the term plastic-mediated magnification to describe the phenomenon that plastics, along with …

Feasibility Of Laser-Induced Breakdown Spectroscopy (Libs) As An At-Line Validation Tool For Calcium Determination In Infant Formula, Xavier Cama-Moncunill, Maria Markiewicz-Keszycka, Yash Dixit, Raquel Cama-Moncunill, Maria Piedad Casado-Gavalda, Patrick J. Cullen, Carl Sullivan

Articles

In this study, a 150 mJ laser-induced breakdown spectroscopy (LIBS) system was assessed to determine calcium content in infant formula (IF) samples. LIBS is a promising emission spectroscopic technique for elemental analysis, which offers advantages over conventional methods such as real-time analyses, little to no sample preparation and ease of use. The aim of this work was to evaluate the feasibility of LIBS as an at-line tool for IF manufacturing. To this end, IF mixtures with varying content of calcium were prepared over a range (approx. 1.5–7 mg/g of calcium) selected to be in conformity with the guidelines provided by …

Facilitating Smart Haccp Strategies With Process Analytical Technology, Fintan Moran, Carl Sullivan, Kevin Keener, Patrick J. Cullen

Articles

The critical feature to any food management system, be it safety or quality focused, is timely and accurate product and process data. The HACCP framework is one of a systematic preventive approach that addresses hazards as a means of prevention rather than finished product inspection. The PAT initiative is a framework which also aims to change product assurance from end-product testing to preventive control through timely measurements of critical product and process parameters. The continued emergence of sensitive yet affordable sensors capable of direct measurement of biological, chemical and physical risks associated with foods during production, processing or over their …

The Application Of Carbon Monoxide In Meat Packaging Needs To Be Re-Evaluated Within The Eu: An Overview, Lauren Anne Van Rooyen, Paul Allen, David I. O'Connor

Articles

Carbon monoxide (CO) has many value-added benefits in meat packaging due to its colour stabilising effects and enhancement of meat quality attributes. The regulation of CO within meat packaging varies worldwide and remains a topical and controversial issue. CO is prohibited in the EU for use in meat packaging mainly due to fears it may mask spoilage therefore misleading consumers. The issue of consumer acceptance of CO was not considered. This article reviews the most pertinent literature to assess if the problems associated with the prohibition have been addressed. Applying CO pretreatments prior to vacuum packaging enhances colour while allowing …

Characterizing The Mechanisms Of Insulin Resistance In Dairy Cattle, Amanda Nicole Davis

Graduate Theses, Dissertations, and Problem Reports (ETD)

Dairy cows transitioning from gestation to lactation experience insulin resistance as maternal adaptation to partition nutrients toward the mammary gland to support milk production. Insulin resistance causes increased lipolysis and free fatty acid (FFA) release into circulation. Unfortunately, this metabolic adaptation occurs during a time when energy demands are heightened and cows are already experiencing negative energy balance. As a result, accelerated hepatic FFA influx promotes hepatic triacylglycerol (TAG) accumulation and ketogenesis, which can cause postpartum metabolic disease. In diabetic monogastrics, mechanisms that mediate insulin resistance involve the sphingolipid ceramide. The role of ceramide in insulin signaling in dairy cows …

Construction Of Bacterial Strains Containing A Plasmid Producing An Opossum-Based Anti-Venom Peptide For Low Cost Production Of The Peptide, Angela Cifelli

Master's Theses

A cost-effective therapy for snake bites and other biological toxins could save thousands of lives each year. A low-cost therapy can be achieved using a bacterial host that expresses a peptide that prevents death when administered after exposure to these toxins. A protein expressed in opossums, lethal toxin neutralizing factor (LTNF), provides the animal’s resistance to venom and a variety of other toxins. A small peptide fragment of this protein provides the same lifesaving properties as the full protein sequence. A synthetic copy of this peptide was tested in mice exposed to rattlesnake venom and showed lifesaving potential. The peptide …

The Perception Of Trust Between Athletic Trainers And Musical Performing Artists, Jenna Lea Chinburg

Parent Beliefs, Attitudes, And Needs In Preschool Age Literacy Development In A Head Start Program, Dianna Jean Mccoy

Theses and Dissertations

The topic of this applied dissertation concerns parents from low socioeconomic status (SES) backgrounds participation in support of literacy development of their preschool aged children. Evidence from the limited research on this topic suggested that some parents rely on the school to teach literacy to their children beginning in kindergarten. Consequently, little time and effort is dedicated to preschool narrative skills, letter knowledge (other than the ABC song), print awareness, phonological awareness, print motivation, and vocabulary.

Literacy development begins before children enter kindergarten. Kindergarten teachers expect children to be able to identify letters, their sounds, print their names. Children without …

Contributors To Processing Speed Deficit In Old Age: A Focus On History Of Obesity And Medical Conditions, Melissa E. Pulcini

Master's Theses and Doctoral Dissertations

Obesity has been associated with impairment in most cognitive domains, but the nature of this relationship is unclear. Most studies have examined the relationship between cognitive impairment and current obesity and/or history of obesity-related medical conditions. However, a number of “lower-level” obesity factors (e.g., increased adipokines, low grade inflammation, chronic mild hypoventilation) are present even among the otherwise healthy obese population, and it is possible that many of these factors have differential impact on cognition according to magnitude and duration of exposure. Knowledge of a person’s weight history, which may serve as a proxy for a number of lower-level obesity …

Role Of Food Preoccupation And Current Dieting In The Associations Of Parental Feeding Practices To Emotional Eating In Young Adults: A Moderated Mediation Study, Natalie A. Williams, Dipti A. Dev, Maren Hankey, Kimberly A. Blitch

Department of Child, Youth, and Family Studies: Faculty Publications

Parental feeding practices reflecting coercive control are related to children’s later eating behaviors, but the mechanisms underlying these effects remain poorly understood. This study examined the relationships between recalled childhood experiences of parental pressure to eat and restriction and current food preoccupation, dieting, and emotional eating in a racially diverse sample of college students (N = 711). Results revealed that parental restriction, but not pressure to eat, was associated with more emotional eating (r = 0.18, p < 0.0001). Food preoccupation mediated the association between restriction and emotional eating (95% CI [3.6495–7.2231]); however, a moderated mediation model revealed that the strength of the indirect effect of restrictive feeding on emotional eating through food preoccupation was significantly different for dieters and non-dieters (index of moderated mediation = 1.79, Boot SE = 0.79; 95% bias-corrected bootstrap CI [–3.5490 to –0.4515]). These findings provide unique insight into the mechanisms linking parental feeding practices with emotional eating in young adulthood. Future studies attempting to clarify the processes through which child feeding practices impact later eating behaviors should consider the role of current dieting.

Implementing The Academy Of Nutrition And Dietetics Benchmarks For Nutrition Education For Children: Child-Care Providers’ Perspectives, Dipti A. Dev, Virginia Carraway-Stage, Daniel J. Schober, Brent A. Mcbride, Car Mun Kok, Samantha Ramsay

Department of Child, Youth, and Family Studies: Faculty Publications

Background — National childhood obesity prevention policies recommend that childcare providers educate young children about nutrition to improve their nutrition knowledge and eating habits. Yet, the provision of nutrition education (NE) to children in child-care settings is limited.

Objective — Using the 2011 Academy of Nutrition and Dietetics benchmarks for NE in child care as a guiding framework, researchers assessed child-care providers’ perspectives regarding delivery of NE through books, posters, mealtime conversations, handson learning, and sensory exploration of foods to young children (aged 2 to 5 years).

Design — Using a qualitative design (realist method), individual, semistructured interviews were conducted …

Explaining And Monitoring Population Performance In Grizzly And American Black Bears, Jeffrey Brian Stetz

Graduate Student Theses, Dissertations, & Professional Papers

Understanding how environmental factors influence wildlife populations is at the heart of ecology and management. Populations and their habitats are, however, inherently dynamic, which requires monitoring responses to changes in the environment. Beyond quantifying population dynamics, understanding why populations respond as they do may allow improved predictions within and across populations, ideally leading to better management. Grizzly bears (Ursus arctos) and American black bears (U. americanus) have been researched in North America for decades, providing excellent opportunities to explore ecological questions involving inter- and intraspecific competition and responses to spatial and temporal variation in resources. The wealth of data collected …

A Biogeographic Perspective On The Impacts And Importance Of Rodent Granivory On Native Vs. Invasive Plants, Jacob Elias Lucero

Graduate Student Theses, Dissertations, & Professional Papers

One of the most well-known explanations for the success of invasive plants in novel environments is enemy release, which predicts that 1) invasive plants are limited by natural enemies in the native range but not the non-native range, and 2) native competitors in recipient communities remain limited by their natural enemies. Despite considerable empirical attention, very few studies have tested these basic predictions, especially with respect to generalist herbivores. We tested whether invasive cheatgrass (Bromus tectorum) has experienced enemy release from granivorous rodents – an important guild of generalists – using exclosures and experimental seed additions in western Asia (where …
