Radiofrequency Inactivation Of Salmonella In Black Pepper And Dried Basil Leaves Using In-Package Steaming, Surabhi Wason, Rossana Villa-Rojas, Jeyamkondan Subbiah

Department of Food Science and Technology: Faculty Publications

Radiofrequency (RF) heating has been extensively studied for pasteurizing low‐moisture foods. Currently, bulk foods are treated with radiofrequency; potential cross‐contamination may occur during packaging of pasteurized products. As an alternative, in‐package RF processing was evaluated for Salmonella inactivation on black peppercorns and dried basil leaves and prevention of cross‐contamination during storage postprocessing. Inpackage steaming refers to the process in which the samples were heated in a steam vent package to generate and retain steam during the treatment. This treatment achieved good heating uniformity which could be because of the circulation of steam within the package. One‐way steam vent allowed the …

Selenium (Se) may help prevent breast cancer (BC) development. Owing to limited observational evidence, we investigated whether prediagnostic Se status and/or variants in the selenoprotein genes are associated with BC risk in a large European cohort. Se status was assessed by plasma measures of Se and its major circulating proteins, selenoprotein P (SELENOP) and glutathione peroxidase 3 (GPX3), in matched BC case-control pairs (2208 for SELENOP; 1785 for GPX3 and Se) nested within the European Prospective Investigation into Cancer and Nutrition (EPIC). Single nucleotide polymorphisms (SNPs, n = 452) in 55 selenoprotein and Se metabolic pathway genes and an additional …

The Effect Of Social Support On Social Media On Asian College Students' Intention To Participate In Physical Activity In The United States, Ni Zhang, Kele Ding, Chulwoo Park, Jane Vo, Katrina Marie Cantos

Faculty Research, Scholarly, and Creative Activity

Background: College students who identified themselves as Asians in the United States (i.e., Asian college students) are facing health inequalities and engaging in increasingly low levels of physical activity (PA). Although social support was found to be effective in increasing college students' PA and social media is an important channel for social support for Asian students, few studies have explored how to provide social support through social media interventions to promote Asian students' PA level. Thus, this study aimed to explore the effects of social support on social media on Asian college students' intention to participate in PA based on …

Spectral Reflectance Indices Associated With Biomass Production Of Cold Stress Resistant White Clover Genotypes Collected In Argentine And Chilean Patagonia, Hernán Acuña, Luis Inostroza, Catalina Vásquez, Joel Ibañez

IGC Proceedings (1977-2023)

White clover (Trifolium repens L.) is the main forage legume species in grazing pastures in central and southern Chile and many other temperate regions of the world. Its growth rate is limited by low temperature, therefore, the selection of cold stress resistant genotypes is an important step for breeding cultivar to improve the clover growth curve and extend the grazing season in early spring and autumn. The main objective of this experiment was to determine the relationship between phenotypic traits, measured by the high-throughput phenotyping procedures based on canopy reflectance at different wavelengths (spectral reflectance indices, SRIs), and dry …

Plantain (Plantago Lanceolata L.) Growth Islimited Under Waterlogging, S. S. Wilson, Daniel J. Donaghy, D. J. Horne, Soledad Navarrete, P. D. Kemp

IGC Proceedings (1977-2023)

Plantain (Plantago lanceolata L.; PL) is becoming an increasingly important component of New Zealand dairy pastures because of its ability to reduce nitrogen losses to the environment. However, widespread suggestions of its poor persistence, have led to industry concern over its suitability for dairy systems. Anecdotal evidence suggests that PL does not cope well in waterlogged soil, yet there is little scientific literature relevant to this issue. Thus, the aim of this study was to investigate the impact of waterlogging stress on PL growth and survival. In a glasshouse, the performance of PL under waterlogging was evaluated against perennial …

IGC Proceedings (1977-2023)

Pastures occupy 30% of Earth and 80% of the entire agricultural area of the planet. To ensure food to the world and contribute to the quality of the environment, pasture-based animal production systems will also have to undergo through a more intense evolution. The intensification of tropical grasslands is an important strategy of land utilization in developing countries, contributing to increase production and minimize environmental impact through the best management practices. In this sense, the use of Brachiaria hybrids represents an excellent option, since combining the best traits of different Brachiaria species, with higher nutritive value, forage, and seed yield. …

Evaluating Functional Diversity As Potential Early-Warning Indicator Of Rangeland Degradation, L.-M. Schwarz, C. P. Carmona, M. C. Bilton, F. Munyebvu-Chambara, K. Behn, A. Linstädter

IGC Proceedings (1977-2023)

Droughts and overgrazing play a crucial role in the degradation of semi-arid rangelands. This is evident in the loss of palatable long-lived grass species and bush encroachment. Early warning indicators are needed to mitigate long-term degradation and decline in essential forage provision. Functional diversity provides valuable information on ecosystem health. However, functional diversity indices have not yet been tested regarding their applicability as early warning indicators, revealing non-linear threshold behaviour. We therefore examined the following questions: (1) How do functional diversity indices respond to grazing pressure? (2) Does land tenure affect the relationship between functional diversity and grazing pressure? (3) …

Integrating Grazing With 2,4-D And Florpyrauxifen To Control Broadleaf Weeds And Maintain Red Clover Productivity In Grass-Legume Pastures, M. J. Renz, G. M. Imhoff

IGC Proceedings (1977-2023)

In grass-legume pastures, 2,4-D-amine + florpyrauxifen-benzyl controls broadleaf weeds but red clover (Trifolium pratense L.) is eliminated. Grazing within a week prior to herbicide application is likely to reduce leaf surface area and may reduce red clover injury and maintain productivity. Experiments were conducted in 2020 and in 2021 to determine if red clover could be productive when 560 g ae ha^-1 2,4-D-amine + 6.3 g ae ha-1 of florpyrauxifen-benzyl with 1% v/v methylated seed oil applied in the spring was grazed before or after herbicide application. Grazing timings occurred 6, 4, or 2 days prior to herbicide …

Enhancing Milk Production Of Lactating Camels In Kenya Via Supplementation Of The Invasive Cactus (Opuntia Stricta) In The Diet, W. O. Owino, Lucy W. Ikanya, J. G. Maina, C. K. Gachuiri, José C. B. Dubeux Jr.

IGC Proceedings (1977-2023)

Climate change leading to prolonged and recurrent droughts, changes in land use, primarily settlement of pastoralists, followed by overgrazing and subsequent land degradation, has made the highly drought resistant opuntia flourish and be aggressively invasive in the Kenya’s rangelands. Camel keeping has increasingly replaced cattle as a climate adaptation strategy and also as a result of a steady increase in demand for camel milk due to the associated nutritional and health benefits,To address the challenge of lack of pasture during prolonged drought, there is the need to utilize the invasive cactus as fodder. The invasive cactus can be a kind …

Normative Does Not Mean Inclusive: A Diverse Approach To Size In Cmhc Training, Courtney Boggs, Melinda Rule, Kassie R. Terrell, Madison Brantley, Hanadi Hamadi, Jenifer M. Ross

Journal of Counselor Preparation and Supervision

The medicalized model of weight and weight loss upholds a Weight Normative Approach which assumes that: (a) weight and disease are positively and causally related, (b) weight loss correlates to better health, (c) bodyweight is controllable, and (d) significant weight loss is possible and sustainable. This approach contributes to harmful societal standards that increase prejudice against fat people. This study examined counselor educators’ (n=88) training, values, and implementation of size and fat phobia-related content in their CACREP-accredited counseling courses. Results indicated that many participants include size and sizeism in their courses; however, participants also reported agreement with tenants of Weight …

Tiller Demography Within Synthetic Grass Populations, K. J. Moore, C. Córdova

IGC Proceedings (1977-2023)

Like other populations of biological organisms, the collective aging structure of a population of grass tillers has meaning and consequences far beyond the development of an individual within it. Using various methods, it is possible to assign numerical indices to tiller development so that it can be described numerically. By sampling a population of tillers and assigning a numerical index to each, the average stage of tillers within a population can be calculated and a repeatable assessment of its development determined. The average or mean stage count (MSC) of tiller development is commonly calculated and used to compare the development …

An Investigation On Food Habits Of Persian Gazelle In Cheshmeh Gol Reproduction Station Of Khorasan Province, Iran, I. Mohammdi-Abiz, Kamal Naseri, Mansour Mesdaghi, H. Yazdandad

IGC Proceedings (1977-2023)

Persian gazelle (Gazella subgutturosa) is one of the most important wild species in Iran. This species prefers plain and low hill habitats which are dominated by sagebrush (Artemisia sieberi). However, due to extensive hunting and habitat destruction, the populations of gazelle were declined and this valuable species was recorded as threatened species in 2006. To rehabilitate the habitats of gazelle and improve their productivity, Cheshmeh-Gol captive reproduction station with an area of 50 hectares was established. To provide more reliable information on diet requirements of gazelle, direct observation and cafeteria feeding on captive animals were employed. …

Natural Regeneration Of Severely Degraded Terrestrial Arid Ecosystems Needs More Than Just Removing The Cause Of The Degradation, M. Louhaichi, M. Gamoun, N. Al Hashash, F. Al-Ameer, D. Alrashedi, A. Redha, F. Alkandari, A. Niane

IGC Proceedings (1977-2023)

Rangelands cover over 75% of Kuwait’s total land area. Most of these rangelands are severely degraded because of overgrazing, poor anthropic utilization, and mismanagement. Restoring natural rangelands is a way to increase forage productivity, enhance biodiversity, and achieve sustainable development. When degradation has not reached the point of irreversibility, natural restoration through resting is one of the best low-cost restoration techniques. This study evaluated the effect of natural restoration on vegetation cover and species richness in the desert rangelands of Kuwait. The studied rangeland was a completely fenced area of 1 km2. The percent of vegetation was measured using the …

Belowground Productivity In Patches Of Heterogeneous Grass Swards After Nearly Two Decades Of Low-Intensity Cattle Grazing, M. Komainda, J. Isselstein

IGC Proceedings (1977-2023)

In low-input grassland, patch-grazing leads to tall and short patches that provide different growth conditions for the grass sward. Since belowground biomass and the associated turnover represent the main carbon input to soil in grassland, we investigated within-pasture variation of above- and belowground net primary production in relation to patches over one year of production in a long-term grazing experiment during the year 2022. The analysis of above- and belowground net primary production showed an effect of patch types, partly in interaction with the month, indicating a strong variation due to climatic conditions. In those few cases where differences existed …

Activity Budget And Foraging Patterns Of Nubian Giraffes (Giraffa Camelopardalis Camelopardalis) In Lake Nakuru National Park, Kenya, Consolata G. Gitau, J. S. Mbau, R. K. Ngugi, A. B. Muneza, E. Ngumbi

IGC Proceedings (1977-2023)

How animals decide to spend their time has a key impact on their survival and reproduction. These behavioral decisions are shaped by ecological and environmental factors, such as seasonal changes. Foraging patterns show how an animal chooses to forage in its environment as influenced by resource availability, competition, and predation risk. Giraffe activity budget has been investigated in populations across Africa and found to be influenced by body size, diet composition, and sex. The activity budget and foraging patterns of Nubian giraffes vary considerably between ecosystems. The Nubian giraffe, a subspecies of the Northern giraffe species (Giraffa Camelopardalis) …

IGC Proceedings (1977-2023)

Aeschynomene (Aeschynomene americana L.) is a warm-season annual legume commonly overseeded into warm-season perennial grass pastures in tropical and subtropical regions. Although aeschynomene usually increases forage production and nutritive value, there is limited information about the ecosystem services provided by this legume. The objective of these studies was to evaluate the effects of overseeding aeschynomene into bahiagrass (Paspalum notatum Flüggé) pastures on nutrient dynamics and microbial N-cycling gene abundances. The studies were conducted in Ona, FL, from April to March 2019-2020 and 2020-2021. Treatments were the split-plot arrangement of two forage systems treatments (overseeding aeschynomene into bahiagrass or …

Sustainable Intensification Of Livestock Systems Using Forage Legumes In The Anthropocene, José C. B. Dubeux Jr., D. M. Jaramillo, E. R. S. Santos, L. Garcia, L. M. D. Queiroz, K. R. Trumpp

IGC Proceedings (1977-2023)

Sustainable intensification of livestock systems implies greater efficiency in resource utilization resulting in greater output of products and other ecosystem services per unit of resource input. Strategies to improve resource use efficiency include diversification of plant and ruminant species with complementary resource use. Forages that have root systems with contrasting architecture and exploring different soil layers with complementary use of resource acquisition (e.g., nutrients, water) could enhance primary productivity. Belowground interactions with soil microbiota (e.g., mycorrhizae) is key to enhance resource utilization. Forages with complementary canopy characteristics that helps enhancing light interception and utilization could also lead to greater resource …
