Designing A Statistical Plan For Measuring Self-Efficacy Using A 2k Factorial Design​, Rachel A. Hart, Eugene H. Thompson

Mathematics, Computer Science & Statistics Presentations

This study focuses on designing a statistical plan that measures the effects of self-efficacy using a 2k factorial design. Specifically, we simulated data on physical, mental, spiritual, and social health, so we could focus on their interaction with self-efficacy. By using ANOVA to see the main and interaction effects, we can see the impact of individual autonomy on health. Our findings show the need for experimental data on the demographic of interest, peri-and post-menopausal women.

Examining The Effects Of Symbiotic State And Environmental Pollution On Wound Healing In Coral, Jonathan De Montagnac

College Honors Program

Understanding coral reef health requires comprehension of the biological processes that support live coral cover. Corals are frequently exposed to physical abrasion from various sources, thereby necessitating vital resources be directed towards wound recovery. For corals and other organisms that harbor photosynthetic symbionts, the balance between autotrophic versus heterotrophic energy contributions influences their fitness. Experimentally disentangling the individual effects of environmental stress and symbiotic state on coral health is difficult in most tropical corals due to the obligate nature of their symbiosis. However, determining how nutritional dynamics, environmental stressors, and health interact is crucial to understanding coral resilience. To examine …

Leveraging Hypersoft Set To Optimize Livestock In The Era Of Unmanned Aerial Vehicles, Alaa Salem, Mona Mohamed, Nebojsa Bacanin, Mohamed Abouhawwash

Neutrosophic Systems with Applications

Due to urbanization and industrialization, rapid global change and the potential loss of arable land, agricultural output must rise in production levels and harvest, distribute, and use resources more efficiently. It is believed that using technology on livestock would help meet the expanding population's demand for food. Internet of Things (IoT) and Unmanned Aerial Vehicle (UAV) integration in conventional farming has transformed operations, providing farmers with greater productivity, improved decision-making, and sustainability. We assume that there are enough UAVs to cover the entire pasture, and our goal is to identify the best UAVs. Accordingly, determining the best type of UAVs …

All Works

Age-related macular degeneration (AMD) is a prevalent retinal disorder in the elderly, often leading to significant vision impairment. The diagnosis of AMD is confirmed through various medical imaging modalities, with color fundus photography (CFP) being a primary tool. The detection and staging of AMD-severity depend on several factors, including the number and size of drusen, the presence of pigmentary changes, geographic atrophy, and neovascularization, all of which are identifiable through CFP. In this study, we introduce an innovative dual-vision transformer-based network designed to automatically detect AMD and classify its severity into either dry AMD or wet AMD using CFP. Early …

Al-Bahir

The CRISPR/Cas9 system is a revolutionary genome-editing tool that enables precise and inheritable modifications, transforming plant genetic engineering. Previous literature has indicated that, in agriculture, CRISPR has improved crop yield, biofortification, and resistance to environmental stressors, fostering resilient and high-yielding crops essential for sustaining a growing global population. In nutraceuticals, CRISPR has enhanced the biosynthesis of bioactive compounds such as anthocyanins, flavonoids, and omega-3 fatty acids, improving the nutritional and therapeutic value of crops.

Despite its immense potential, CRISPR technology faces technical, ethical, and regulatory challenges, including off-target effects, accessibility concerns, and public acceptance. Addressing these issues is crucial for …

Forage Crop Improvement Through Biotechnology, S S. Croughan

IGC Proceedings (1977-2023)

Bermudagrass (Cynodon dactylon) is a perennial forage grass grown on over 10 million ha worldwide. In the southern United States, it is used extensively for grazing and the production of hay. It is a well adapted grass, but improvements in traits such as forage quality and pest resistance are needed. Much vari­ation in the nutritional value exists between genotypes. Tissue culture offers a method for the production of improved germ­plasm. Most plants regenerated from callus cultures will vary from the original variety from which they were derived. This phenomenon is referred to as somaclonal variation and can be …

Apomixis And Sexuality In Brachiaria Decumbens Stapf., C B. Do Valle, Y H. Savidan, L Jank

IGC Proceedings (1977-2023)

Brachiaria decumbens Stapf is a perennial tropical forage grass, native to east African savannas. It was introduced to Brazil in the 1960's and is now widely cultivated over 30 million hectares in Central Brazil alone. The two commercial varieties are apomictic tetraploids (2n = 4x = 36), producing uniform progeny, and were selected for their high dry matter production and persistence on poor acid soils. They lack, however, resist­ance to spittlebugs (Deois spp., Zulia spp., Aeneolania spp.) and produce forage of low nutritive value, especially during the dry winter months. The absence of natural variability associated to apomictic reproduction has …

Use Of New Methods For Grass And Legume Breeding In Western Region Of The Soviet Union, R Dapkus

IGC Proceedings (1977-2023)

The climatic conditions of the Western region of the Soviet Union are favourable for grassland production which provides the major part of forage for livestock nutrition. In raising grassland productivity, new varieties play an important role. Adapted varieties with high yield potential must be used. For developing such varieties, the Fodder Crops Breeding Centre fbr the Western region of the Soviet Union was estab­lished at the Lituanian Agricultural Research Institute in 1972 on the basis of experience since 1922, when selection of herbage species was initiated there. During the past twenty years, breed­ing work has progressed rapidly. At present, breeding …

Overall Quality And Quantity Evaluations Of Native Ecotypes Of Crested Wheatgrasses Of Iran, B Peymani-Fard

IGC Proceedings (1977-2023)

Agropyron cristatum (L.) Gaertn (crested wheatgrass) is indigenous to central Asia including parts of the USSR, China, Afghanistan, Turkey and Iran (Bore, 1970). It is a perennial tufted grass which often grows naturally on stony slopes and calcareous soils. In very hot dry periods it tends to remain dor­mant but renews its growth as soon as its moisture supply returns to normal. It also survives the coldest temperature encountered in its area of adaptation (Rogler, 1960). The toler­ance of Agropyron cristatum to heavy spring grazing results from early root activity, early accumulation of leaf tissue and significant accumulation of carbohydrates …

The Potential Of Lolium Multiflorum X Festuca Gigantea Hybrids, M O. Humphreys, H Thomas, B F. Tyler

IGC Proceedings (1977-2023)

The potential for combining traits from broadly adapted Festuca with more highly specialised Lolium has been investi­gated for many years especially with regard to cytological behaviour (Breese et al., 1981). In the USA, efforts to increase the nutritive value of tall fescue through hybrids with ryegrasses succeeded in producing the variety Kenhy (Buckner et al., 1977). So far, Lolium/Fescue hybrids have not been able to compete commercially with more productive ryegrasses in intensive UK farming systems (Breese and Lewis, 1984). How­ever, with recent economic changes in European agriculture there is a need for more efficient, lower input grassland …

Comparative Study Of Some Varieties Of Cowpea I- Productivity And Nutritive Analysis, K M. Ghobrial, M A. Gabra

IGC Proceedings (1977-2023)

In Egypt, the serious problem of feed shortage, especially of green summer fodder suppresses the improvement of animal production. Therefore, dependence on improving local food and food resources for both animals and humans becomes a «must» for a right policy. The animal feeding system is depen­ding on the cultivation of berseem (Trifolium alexandrium L.). It produces annually around 4.81 million tons starch value/year and could cover the requirements of animals with surplus of 0.92 million tons starch value. However, in summer period, there will be at least a deficiency of 1.50 million tons starch value and most animals are …

IGC Proceedings (1977-2023)

During one of the joint plant exploration missions between CIA T's Tropical Pastures Program and national research institutions which aim at building up a comprehensive inter­national forage germplasm collection for development of acid­soil tolerant cultivars (Schultze-Kraft, 1985), an unknow Cen­trosema species was collected. It is closely related to C. brasili­anum and was recently described as C. tetragonolobum (Schultze-Kraft and Williams, in press). Its natural distribution is restricted to the Orinoco region in Colombia and Venezuela between latitudes 4° and 6° N. At present 12 germplasm accessions are available. They were collected during 1984-86 on acid soils (pH 4.5-5.5) and in …

L’Amatante (Amaranthus Retroflexus L.) Comme Plante Fourragere, L Bosch, F Casanas, A.M.C Verdu

IGC Proceedings (1977-2023)

L'amarante est une des mauvaises herbes !es plus communes dans nos champs. Elle parvient a etouffer la culture principale si on ne la contr6le pas correctement. Elle a une germination maximale en fin de printemps et en debut d'ete, bien que la ger­mination continue pendant tout l'ete, favorisee par Jes hautes temperatures et la lumiere intense (Baskin et Baskin, 1977). Sa croissance rapide s'explique par le fait qu'il s'agit d'une plante en C-4 specialement efficace pour la captation de CO2 puis­qu'elle a des cloisons cellulaires tres minces (Longstreht et al., 1980). Elle presente aussi une remarquable capacite de repousse apres …

Morpho-Physiological Aspects And Nutritive Value Of Brachiaria Brizantha Cv. Marandu And Heteropogon Sp Affected By The Plants' Age, V. De B.G Alcantara, A.R P. De Almeida, P B. Alcantara, G Braun, E L. Caielli

IGC Proceedings (1977-2023)

Grazing pressure must be related to the pasture potential capacity of recovery. The measurement of leaf area index (LAI) is a way of evaluating that effect. Whatever the management, the main objective will be to allow pasture to reach a high LAI status and its' maintenance (Peterson, 1970). In elephant grass the stem/leaf ratio was used to indicate the dry matter production and indirectly indicates the grazing pressure (Rodrigues, 1984). Present experiment was done to evaluate the evolution of leaf area index (LAI), leaf/stem ratio (L/S), percentages of crude protein (CP), crude fiber (CF) and in vitro dry matter digesti­bility …

Factors Affecting Isotopic Fractionation During Nitrogen Fixation By Pasture Legumes, S F. Ledgard

IGC Proceedings (1977-2023)

The ¹⁵N natural abundance method for measuring N₂ fix­ation by legumes has compared favourably with other methods (reviewed by Shearer and Kohl, 1986). This method is based on the small difference in ¹⁵N abundance between nitrogen (N) derived from N2 fixation and N derived from soil. The pro­portion of legume N fixed from atmospheric N2 (PN) is cal­culated using :

PN = (o¹⁵Nref - o¹⁵N1egume)/(0¹⁵Nref - B)

where o¹⁵N is the per mil ¹⁵N excess over atmospheric N₂ ; ref is a reference plant which obtains all …

Effect Of Nitrogen On Herbage Growth And Intake By Sheep In Continuously Grazed Swards Of Tall Fescue Genotypes, A Mazzanti, G Lemaire, F Gastal

IGC Proceedings (1977-2023)

Relatively little is known about the growth of tall fescue under continuous grazing. Most of reported works about herb­ age production in such a grazing management have been done with perennial ryegrass and with relatively high levels of nitro­ gen fertilisation (Hodgson, 1981 ; Bircham, 1981; Parsons et al., 1983). The effect ot the level N nutrition on growth of a continuously grazing sward has not been yet studied. On intermitently defoliated swards of tall fescue, Gastal & Lemaire (1988) have shown that with non limiting level of N nutrition the increase in dry matter production could be 4 or …

Stand Characteristics Of Irrigated Cocksfoot Regrowth And Leaf Area Increasing, M Duru, A Langlet, S Rouzies

IGC Proceedings (1977-2023)

For grasses, high leaf area index (LAI) extension rate is necessary to intercept much radiation and to increase the growth rate (Gosse et al., 1986). The LAI extension rate depends on stand status just after the cut : tiller density (Nelson and Zarrough, 1981), residual leaf area and reserves level (Smith, 1974), plant nutrition (nitrogen especially). We study the setting up of LAI for vegetative regrowths according to nitrogen nutrition and different stand status : tiller number and size.

Growth And Gas Exchange Of Rhizoma Peanut (Arachis Glabrata Benth.) Subjected To Water Deficit, K A. Albrecht, J M. Bennett, G M. Prine

IGC Proceedings (1977-2023)

Rhizoma peanut (Arachis glabrata Beuth.) is a long lived per­ennial forage legume adapted to well drained soils of Florida and the humid tropics and subtropics that are prone to both long and short term moisture deficits. The nutritive value of rhizoma peanut is similar to that of alfalfa, thus it is an excel­lent supplement to tropical grass pastures. Prine (1983) reported that yields of 11 t/ha are regularly obtained in north­ern Florida and that yield potentials could be greater in areas with longer growing seaso��and well distributed rainfall. The influence of dryught on yield and physiological responses of rhizoma …
