Faculty Publications in Food Science and Technology

A prototype on-line acousto-optic tunable filter (AOTF)-based hyperspectral image acquisition system (λ = 450– 900 nm) was developed for tenderness assessment of beef carcasses. Hyperspectral images of ribeye muscle on stationary hanging beef carcasses (n = 338) at 2-day postmortem were acquired in commercial beef slaughter or packing plants. After image acquisition, a strip steak was cut from each carcass, vacuum packaged, aged for 14 days, cooked, and slice shear force tenderness scores were collected by an independent lab. Beef hyperspectral images were mosaicked together and principal component (PC) analysis was conducted to reduce the spectral dimension. Six different textural feature ...

Quantifying Land Cover Change Due To Petroleum Exploration And Production In The Haynesville Shale Region Using Remote Sensing, Daniel Unger, I-Kuai Hung, Kenneth W. Farrish, Darinda Dans

Faculty Publications

The Haynesville Shale lies under areas of Louisiana and Texas and is one of the largest gas plays in the U.S. Encompassing approximately 2.9 million ha, this area has been subject to intensive exploration for oil and gas, while over 90% of it has traditionally been used for forestry and agriculture. In order to detect the landscape change in the past few decades, Landsat Thematic Mapper (TM) imagery for six years (1984, 1989, 1994, 2000, 2006, and 2011) was acquired. Unsupervised classifications were performed to classify each image into four cover types: agriculture, forest, well pad, and other ...

Seed Set And Xenia Effects On Grain Iron And Zinc Density In Pearl Millet, Mahalingam Govindaraj

Mahalingam Govindaraj

Three types of seed samples (selfed, sibbed and open pollinated) can be used for mineral analysis in pearl millet [Pennisetum glaucum (L.) R. Br.] and other cross-pollinated crops. Cost effectiveness and reliability of mineral estimates in these types of seed samples have a direct bearing on breeding efficiency. Three sets of experiments using a diverse range of materials were conducted to examine the potential use of selfed and open pollinated (OP) seed samples for the analysis of grain Fe and Zn density in pearl millet. The results of this study showed that reduction in seed set under selfing, a genotype- ...

Ship-Induced Solitary Riemann Waves Of Depression In Venice Lagoon, Kevin E. Parnall, Tarmo Soomere, Luca Zaggia, Artem Rodin, Giuliano Lorenzetti, John Rapaglia, Gian Marco Scarpaf

Biology Faculty Publications

We demonstrate that ships of moderate size, sailing at low depth Froude numbers (0.37–0.5) in a navigation channel surrounded by shallow banks, produce depressions with depths up to 2.5 m. These depressions (Bernoulli wakes) propagate as long-living strongly nonlinear solitary Riemann waves of depression substantial distances into Venice Lagoon. They gradually become strongly asymmetric with the rear of the depression becoming extremely steep, similar to a bore. As they are dynamically similar, air pressure fluctuations moving over variable-depth coastal areas could generate meteorological tsunamis with a leading depression wave followed by a devastating bore-like feature.

Corn Response To Foliar-Applied Zinc Fertilizers, A. Lamb, N. O. Nelson

Kansas Agricultural Experiment Station Research Reports

This study was conducted to determine corn response to three foliar-applied zinc sources. The study was conducted on dryland corn in Manhattan, KS, during the 2014 growing season. Yields were low as a result of very low precipitation during pollination and grain fill. There was no yield response to foliar-applied Zn; however, grain analysis show significant increases in grain Zn concentration from foliar-applied Zn. Foliar-applied Zn products are effective for increasing Zn uptake in corn. Additional studies need to be conducted to determine the yield response.

Lactipro (Megasphaera Elsdenii) Increases Ruminal Ph And Alters Volatile Fatty Acids And Lactate During Transition To An 80% Concentrate Diet, J. Thieszen, C. L. Van Bibber, J. E. Axman, J. S. Drouillard

Kansas Agricultural Experiment Station Research Reports

Direct-fed microbials commonly have been used to enhance performance or to decrease shedding of foodborne pathogens in beef cattle. Megasphaera elsdenii is a recently introduced probiotic bacteria marketed under the trade name Lactipro (MS-Biotec Inc., Wamego, KS) and is a key lactate-fermenting bacterium in the rumens of cattle fed high-concentrate diets. Megasphaera elsdenii is responsible for metabolizing up to 95% lactic acid within the rumen, and thus is an important species for controlling occurrence of ruminal acidosis. The objective of this study was to evaluate changes in ruminal pH and volatile fatty acid concentration during the transition from a diet ...

Corn Yield Response To Plant Populations, D. E. Shoup, E. A. Adee, I. A. Ciampitti

Kansas Agricultural Experiment Station Research Reports

Corn hybrid development with a focus on drought tolerance has emerged in recent years, and producers have questions about their yield performance across a range of plant populations. A two-year study was conducted to determine the yield of corn hybrids across several plant populations. Corn hybrids responded differently in 2013 and 2014. In 2013, a lower yield environment occurred. The hybrid with drought tolerance had the greatest yield of 95 bu/a at a plant population of 21,500 plants/a, whereas the non-drought-tolerant hybrid’s greatest yield was 90 bu/a at a plant population of 13,500 plants ...

A corn research trial was conducted at Scandia, KS, during the 2014 growing season. The objective was to study the contribution of different farming systems in developing efficient and high-yielding corn production systems. The experiment had five treatments: farmer practices, comprehensive fertilization, production intensity, ecological intensification, and advanced plus. Farmer practice was the lowest-yielding treatment, and ecological intensification and advanced plus treatment presented similar yields.

Influence Of Different Seeding Dates On Fenugreek (Trigonella Foenum-Graecum L.) Forage Yield And Nutrient Value, A. Obour, E. Obeng, J. D. Holman

Kansas Agricultural Experiment Station Research Reports

Fenugreek (Trigonella foenum-graecum L.) is used as medicinal plant in many Asian countries and has been reported to have forage quality similar to alfalfa. Fenugreek is an annual crop and may have the potential to diversify forage production systems in the central High Plains. This study evaluated forage dry matter (DM) production and the nutritive value of three fenugreek cultivars as influenced by planting date at Hays and Garden City, KS, in 2014. Results at Hays showed forage DM yield of fenugreek cultivars was not affected by planting date, but fenugreek cultivars differed significantly (P < 0.05) in forage DM yield. Averaged across planting date, forage DM production was 760 lb/a for ‘Amber,’ 910 lb/a for ‘F96,’ and 672 lb/a for ‘Tristar.’ Forage crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrient (TDN) concentrations, and relative feed value (RFV) did not differ (P > 0.05) among fenugreek ...

A Bioinformatics Approach To Revealing The Genetic Basis For Host Range Specificity, Hayley A. Norian

James Madison Undergraduate Research Journal

Bacteriophages, or phages, are viruses that infect bacteria. Mycobacteriophages are bacteriophages that specifically infect the genus Mycobacterium. This genus of bacteria includes human pathogens such as Mycobacterium tuberculosis, Mycobacterium leprae and Mycobacterium ulcerans, which cause tuberculosis, leprosy and Buruli ulcer, respectively. The full genome sequences of 654 mycobacteriophages are currently available. Collectively, these 654 phages encode 69,581 genes. Only 20.25% of these genes have at least one known homologue in NCBI, the National Center for Biotechnology Information, leaving roughly 80% of all known mycobacteriophage genes without even a predicted function. Bacteriophages are highly host-specific and typically only infect ...

Nitrogen And Sulfur Fertilization Effects On Camelina Sativa In West Central Kansas, E. Obeng, A. Obour

Kansas Agricultural Experiment Station Research Reports

Camelina sativa is early maturing and possesses characteristics that make it a good fit as a rotation crop in dryland wheat cropping systems. Nitrogen (N) and sulfur (S) play very important roles in oilseed production, including camelina. This study was undertaken in 2013 and 2014 to determine N and S rates necessary for optimum camelina production in West Central Kansas. The experiment was set up as randomized complete blocks with four replications in a split-plot arrangement. Treatments were four N rates (0, 20, 40, and 80 lb/a) as the main plots, and S rate (0 and 18 lb/a ...

Seeding Date Effects On Camelina Seed Yield And Quality Traits, E. Obeng, A. Obour

Kansas Agricultural Experiment Station Research Reports

Identifying crops that are adapted to dryland environments of the central and northern Great Plains (GP) has been a major challenge. An alternative crop with potential for dryland crop production in the GP is camelina (Camelina sativa L. Crantz). Time of planting is an important management consideration that can affect camelina production. Early planting allows camelina to mature before the onset of hot summer temperatures in the central GP that can affect seed yield. A study was carried out in the spring of 2013 and 2014 to evaluate planting date effects on spring camelina varieties grown under dryland conditions in ...

Cyanobacteria, Algae And Microfungi Present In Biofilm From Božana Cave (Serbia), Slađana Popović, Gordana Subakov Simić, Miloš Stupar, Nikola Unković, Dragana Predojević, Jelena Jovanović, Milica Ljaljević Grbić

International Journal of Speleology

Phototrophic microorganisms (cyanobacteria and algae) and microfungi, were identified from biofilm on the walls of the entrance of BožanaCavein west Serbia. Temperature, relative humidity and light intensity were measured, and chlorophyll a content determined. Light intensity differed from the entrance inwards. However, Chl a content was not proportional to light intensity, instead it was positively correlated to biofilm weight. Biofilm samples from two sites were also observed using a scanning electron microscope. Coccoid forms of cyanobacteria were abundant at the sampling site with the lowest light intensity, while members of the order Nostocales were predominant at the sampling site with ...

Modeling Predator Habitat To Enhance Reintroduction Planning, Shiloh Michael Halsey, William J. Zielinski, Robert M. Scheller

Environmental Science and Management Faculty Publications and Presentations

Context

The success of species reintroduction often depends on predation risk and spatial estimates of predator habitat. The fisher (Pekania pennanti) is a species of conservation concern and populations in the western United States have declined substantially in the last century. Reintroduction plans are underway, but the ability of the species to establish a selfsustaining population is affected by predation from its primary predator, the bobcat (Lynx rufus).

Objectives

To develop a habitat model that incorporates both habitat of the focal species and the spatial patterning of predator habitat. To locate areas of densely aggregated habitat that would be suitable ...

Evaluating The Effectiveness Of Iron Chelates In Managing Iron Deficiency Chlorosis In Grain Sorghum, A. Obour, R. Perumal

Kansas Agricultural Experiment Station Research Reports

Grain sorghum production in alkaline or calcareous soils is frequently affected by iron (Fe) chlorosis. Soil conditions such as high pH, high free calcium carbonate (lime), and low organic matter favor development of iron deficiency chlorosis (IDC), which can delay crop maturity and reduce yields. Two field experiments were conducted in the summer of 2014 to determine the effectiveness of Fe chelate application in alleviating IDC in grain sorghum. Treatments in the first study were four Fe chelate application rates (0, 3, 6, and 9 lb/a) applied either in-furrow with the seed at the time of planting or 2 ...

Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond

Kansas Agricultural Experiment Station Research Reports

Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated corn in western Kansas. In 2014, N applied alone increased yields 58 bu/a, whereas P applied alone increased yields only 12 bu/a. Nitrogen and P applied together increased yields up to 152 bu/a. This is slightly above the 10-year average, where N and P fertilization increased corn yields up to 146 bu/a. Application of 120 lb/a N (with P) produced about 91% of maximum yield in 2014, which was similar to the 10-year average. Application of 80 ...

Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Grain Sorghum, A. Schlegel, H. D. Bond

Kansas Agricultural Experiment Station Research Reports

Long-term research shows that phosphorus (P) and nitrogen (N) fertilizer must be applied to optimize production of irrigated grain sorghum in western Kansas. In 2014, N applied alone increased yields 49 bu/a, whereas N and P applied together increased yields up to 81 bu/a. Averaged across the past 10 years, N and P fertilization increased sorghum yields up to 73 bu/a. Application of 40 lb/a N (with P) was sufficient to produce more than 80% of maximum yield in 2014, which almost equals the 10-year average. Application of potassium (K) has had no effect on sorghum ...

High-Density Lipoprotein Antioxidant Responses To High-Intensity Interval And Steady-State Moderate-Intensity Exercise, Zacharias Papadakis, Jeffrey S. Forsse, Annie A. Bane, Taylor Kyle, Li Qian, Flor Elisa Morales Marroquín, Peter W. Grandjean

International Journal of Exercise Science: Conference Proceedings

High-intensity interval exercise (HIIE) may impart health benefits beyond what is acquired through moderate-intensity steady state exercise (SSE). Paraoxonase 1 (PON1), an antioxidant associated with high-density lipoprotein (HDL), may be altered with exercise; however, it is unclear whether HIIE provides a greater stimulus for increasing PON1 antioxidant activity than a comparable or greater amount of SSE. PURPOSE: Determine the influence of HIIE on PON1 concentration and activity relative to a comparable amount of moderate-intensity SSE and a dose that is half that of SSE. METHODS: Seventeen male participants (age 27.8 + 6.4 yr; weight 80.6 + 9.0 kg ...

The Effects Of Physical Activity On Markers Of Hepatic Inflammation During Weight-Loss, Andrew Seija, Kaylee E. Poole, Kevin Eck, Matthew Harris, Tayler N. Nick, Joshua S. Wooten

International Journal of Exercise Science: Conference Proceedings

Non-alcoholic fatty liver disease (NAFLD) represents a continuum that begins with accumulation of lipid in hepatic cells progressing to hepatic steatosis with inflammation (steatohepatitis), fibrosis, and cirrhosis. Weight-loss using dietary modification and physical activity are common strategies used for the treatment of NAFLD; however, it remains to be determined the effects of physical activity on hepatic inflammation during weight-loss. The purpose of this study was to determine the therapeutic role of physical activity on plasma and hepatic inflammatory markers during weight-loss. Male C57BL/6 mice were fed either a low-fat (LFD; 10% kcal fat) or high-fat (HFD; 60% kcal fat ...
