Food and Machinery

Moisture content and temperature variation of cut tobacco during convective drying were detected with the different hot air temperature from 70 ℃ to 120 ℃. The heat and mass transfer model for the variation of cut tobacco surface temperature with moisture content was established, and the characteristic temperature was proposed to characterize the heating degree of cut tobacco in the drying process. Then the correlation between the physicochemical properties of cut tobacco and the characteristic temperature was analyzed after the end of drying (12.5% moisture content of wet base). The results were present as follows: ① Heat and mass transfer …

Is Tb Testing Associated With Increased Blood Interferon-Gamma Levels?, Aideen E. Kennedy, Jim O'Mahony, Noel Byrne, John Macsharry, Riona G. Sayers

Department of Biological Sciences Publications

The Republic of Ireland reports a relatively low prevalence of Johne’s disease (JD) compared to international counterparts. Postulated reasons for this include a lower average herd size and a grass-based production system. Ireland also engages in high levels of bovine tuberculosis (bTB) testing. As interferon-gamma (IFN-γ) is believed to play a key role in protecting against JD, it is our hypothesis that administration of purified protein derivative (PPD), as part of the bTB test, is associated with a systemic increase in IFN-γ production, which may potentially limit clinical progression of the disease. We studied 265 cows (202 Friesian and 63 …

Hedonic Pricing Of Chocolate Quality Characteristics: Is There A Difference For Fruit Or Nut Chocolate?, Willie B. Bedell, Michael R. Reed

Agricultural Economics Presentations

Chocolate campaigns in the United States have focused on the production of premier quality and healthy blend chocolate bars. We expect that merchandising efforts will offer a higher price for fruit or nut blend chocolates. Using online retail data from Amazon, eBay, and Walmart, we applied the hedonic function to estimate retailers offer price for a blended bar. The findings show that online retailers have mixed offer prices for a blend or plain bar. The paper suggests that studies would learn much more from a data and analysis that control for quantity sold and time effects in the chocolate market.

Strengthening Quality Of Life In Small Towns, Cheryl A. Burkhart-Kriesel

Cornhusker Economics

Quality of life is often mentioned as the reason why some people choose to live in a small town. But if you try to get a definition of what quality of life means, you quickly discover that there are all kinds of answers. For instance, it may be the low student-to-teacher ratios in the local school, or it may be the friendly check-out person at the grocery store or the variety of activities available through civic organizations and local churches which come to mind when people define small town quality of life.

Substantial Contribution Of Genetic Variation In The Expression Of Transcription Factors To Phenotypic Variation Revealed By Erd-Gwas, Hung-Ying Lin, Qiang Liu, Xiao Li, Jinliang Yang, Sanzhen Liu, Yinlian Huang, Michael J. Scanlon, Dan Nettleton, Patrick S. Schnable

Department of Agronomy and Horticulture: Faculty Publications

Background: There are significant limitations in existing methods for the genome-wide identification of genes whose expression patterns affect traits.

Results: The transcriptomes of five tissues from 27 genetically diverse maize inbred lines were deeply sequenced to identify genes exhibiting high and low levels of expression variation across tissues or genotypes. Transcription factors are enriched among genes with the most variation in expression across tissues, as well as among genes with higher-than-median levels of variation in expression across genotypes. In contrast, transcription factors are depleted among genes whose expression is either highly stable or highly variable across genotypes. We developed a …

Symptoms And Causes Of Foamy Bloat In Cattle, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

The bovine stomach normally produces gases such as ammonia, carbon dioxide and methane. However when these gases become trapped in the bovine stomach because of a thick, frothy or foamy liquid it is called bloat. Cattle bloat is a very old condition and goes by many names but is primarily trapped gas within the bovine stomach. Readily digested feedstuff such as highly processed grain diets or an overabundance of fresh immature alfalfa often leads to a vast amount of small particles and carbohydrates in the rumen; this is the major cause of foamy bloat. Severe bloat causes death by suffocation …

The Future Of Food In Blade Runner 2049, Diarmuid Cawley

Other resources

The science fiction genre has always been a hotbed for questions about the existence of life and what it means to be human. Food, like water and oxygen, is necessary to sustain life, but also is a key indicator of culture. One of the things that fascinates us about science fiction is how an imagined future culture might look. Blade Runner 2049, although not centred around food, interweaves food and agriculture into a dystopian narrative on evolution and a bio-engineered labour force, while asking us what it means to have memories and to be human.

Trophic Roles Of Tadpoles In Tropical Australian Streams, Katrin Schmidt, Melanie L. Blanchette, Richard G. Pearson, Ross A. Alford, Aaron M. Davis

Research outputs 2014 to 2021

Tadpoles can be abundant consumers in stream ecosystems, and may influence the structure and function of streams through their feeding activities and interactions with other organisms. To understand the contribution of tadpoles to stream functioning, and the potential impact of their loss, it is necessary to determine their diets and how they might influence food-web structure. Using gut-content analysis and stable-isotope analysis of N and C, we determined the main food sources and trophic positions of tadpoles of five native frog species, invertebrates, and fish in upland and lowland Australian Wet Tropics streams. Omnivory was prevalent among the tadpoles and …
