Variability And Correlations Of Some Investigated Traits Of Perennial Ryegrass Populations, D. Sokolovic, S. Ignjatovic, Z. Tomic

IGC Proceedings (1977-2023)

Perennial ryegrass (Lolium perenne) is one of the most important perennial forage grasses for temperate climates. It is a highly productive grass with the highest nutritive value (Sokolovi et al., 2002). In Serbia, breeders have developed perennial ryegrass cultivars with high stabile yield and quality with different times of maturity and resistance to drought and frost. The initial breeding material were usually wild populations (Charmet et. al., 1996) with high variability and adaptability. These characteristics lend themselves for selection of superior genotypes. But breeding for some important agronomic traits may influence others. This relationship between traits …

Cattle Production From Native Pastures In The Semi-Humid Grasslands Of Uganda, S. Okello, Elly N. Sabiiti

IGC Proceedings (1977-2023)

The cattle population of Uganda, estimated at 6 million, consists of more than 95% indigenous stock, raised on the semi-arid and semi-humid grasslands that make up 48% of the total land area and which supply over 85% of the marketed milk and meat. Native grassland pastures, which vary seasonal in quantity and quality due to rainfall and temperature variations, are the sole feed resource for cattle (Mbuza et al., 1992). This study examined the effects of seasonal herbage mass (HM), dietary crude protein (CP_d), detergent lignin (ADL_d) and digestibility (DiG) on body condition scores of …

The Seasonal Dry Matter Production And Carrying Capacity Of Kikuyu Oversown With Ryegrass And Clover, Philip R. Botha, Robin Meeske, Hennie A. Snyman

IGC Proceedings (1977-2023)

In the main milk producing areas of the Southern Cape, kikuyu (Pennisetum clandestinum) is considered an important summer and autumn pasture which is climatologically well adapted. The main problem experienced with kikuyu is that winter and spring production is low and the exclusion of legumes make it dependent of nitrogen fertiliser and that increases the input cost. The aim of the study was to quantify the seasonal dry matter (DM) yield and carrying capacity of kikuyu (K) through treatments involving kikuyu oversown with annual ryegrass (Lolium multiflorum spp.) (KR), kikuyu oversown with a mixture of perennial ryegrass …

The Seasonal Botanical Composition, Calcium And Phosphorus Content Of Kikuyu Oversown With Ryegrass And Clover, Philip R. Botha, Robin Meeske, Hennie A. Snyman

IGC Proceedings (1977-2023)

Kikuyu (Pennisetum clandestinum) is one of the major grasses used for summer and autumn grazing in the Southern Cape coast area of South Africa. Annual ryegrass (Lolium multiflorum spp.), perennial white (Trifolium repens) and red clover (Trifolium pratense) can be incorporated into an existing kikuyu stand to improve pasture quality and spring production. The aim of this study was to determine the persistence of these species and effects on the calcium and phosphorus content of kikuyu (K), kikuyu oversown with annual ryegrass (KR), kikuyu oversown with a mixture of perennial ryegrass (L. …

Variability In Quantity And Composition Of Water Soluble Carbohydrates Among Irish Accessions And European Varieties Of Perennial Ryegrass, S. Mcgrath, S. Barth, A. Frohlich, M. Francioso, S. A. Lamorte, T. R. Hodkinson

IGC Proceedings (1977-2023)

The objective of this study was to identify perennial ryegrass accessions displaying high fructose and glucose contents and an improved ratio between fructose and glucose fractions across different time points throughout the year. Fructose and glucose are the main constituents of the water soluble carbohydrate (WSC) fraction in perennial ryegrass. For animal nutrition the amount of WSC is crucial as it is the primary energy source available to metabolise the intake of plant protein. The ratio between fructose and glucose fractions is important since fructosan chains, which are an excellent energy source for ruminants, are built from fructose. Furthermore the …

Using Integral Projection Models To Explore Management Strategies For Silver Carp (Hypophthalmichthys Molitrix), Cameron Coles, Elizabeth Balas, James Peirce, Greg Sandland, Richard Erickson

Spora: A Journal of Biomathematics

Silver carp (Hypophthalmichthys molitrix) are planktivorous fish that were originally introduced to the United States for use in fish production ponds and have since escaped these enclosures and are invading the Mississippi River Basin. The silver carp invasion of the Illinois River has a myriad of negative effects on native ecosystems. In this paper, we introduce key dependencies that are likely important in the population dynamics of silver carp: length-dependent egg production and density-dependent growth. Using movement data between two adjacent pools of the Illinois River, we conduct numerical simulations to explore the theoretical effect of harvesting and …

A Mathematical Model For Mosquito Population Dynamics, Christian Evans, Jemal Mohammed-Awel, Andreas Lazari

Georgia Journal of Science

In this study, a deterministic mathematical model for mosquito population dynamics is presented. The use of chemical insecticide to control population is incorporated into the model. It is assumed that there is insecticide sensitive (sensitive-type) and insecticide resistant (resistant-type) mosquitoes in the environment. Conditions for the existence and stability of four equilibria of the model have been established. Numerical simulations are carried out to confirm the analytical results and the implications, in terms of mosquito control in the environment, are discussed.

The De-Indigenisation Of The English Language: On Linguistic Idiosyncrasy, Fayssal Bensalah

Journal of Creative Writing Studies

This paper introduces and explains a fresh adaptation of linguistic hybridity. This creative strategy is common among postcolonial, transnational and transcultural writers, who would import linguistic features from their first languages to hybridise their prose and paint it with a distinctive identity. I aim, however, to demonstrate that my English text can be hybridised without looking outside the English language, but rather by looking within it. The English language, as I argue, is already a hybrid language, populated by thousands of words borrowed from various languages, including Arabic. The words of this latter, if used intelligently and selectively in my …

A Survey Of European Regional Adaptation In Italian Ryegrass Varieties, T. J. Gilliland, A. J. P. Van Wijk

IGC Proceedings (1977-2023)

Ryegrass is widely adapted to cool temperate eco-zones and breeders often submit individual varieties for testing in a number of EU countries. National testing programmes often combine data from several trial sites that may differ climatically, but not from sites in other member states, despite the possibility of high ecological similarity. Given increasing interest in animal value characters (soluble sugars, lipids, sward geometry), additional testing for these would be valuable but is prohibited by capped or declining funding. Data sharing between EU national authorities could be advantageous but is inhibited by the lack of statistically valid data on the sensitivity …

Milk Production Potential Of Different Dairy Pasture Types In Southern Australia, J. Tharmaraj, D. F. Chapman, Z. N. Nie, A. P. Lane

IGC Proceedings (1977-2023)

The growth rate of traditional perennial ryegrass-based pastures commonly fails to meet herd feed requirements through winter and summer in non-irrigated dairy systems in southern Australia. Alternative pasture species can improve seasonal feed supply in this region (Tharmaraj & Chapman, 2005). However, the feeding value and milk production of these pastures must at least match perennial ryegrass if they are to be adopted successfully on dairy farms. This paper reports results of a comparison of the milk production potential of pasture types similar to those investigated by Tharmaraj & Chapman (2005) for their agronomic performance.

Effect Of Strain Of Holstein-Friesian Cow And Feed System On Reproductive Performance In Seasonal-Calving Milk Production Systems Over Four Years, B. Horan, J. F. Mee, Myles Rath, P. O'Connor, P. Dillon

IGC Proceedings (1977-2023)

In Ireland most dairy farms operate seasonal calving grass-based milk production systems. Feed demand and supply are matched by having calving highly concentrated in spring. This requires high pregnancy rates within a short time following the start of mating in late April or early May, but has become increasingly difficult to achieve due to declining fertility in Irish dairy herds (Mee, 2004). In New Zealand, cows of North American Holstein-Friesian origin have poorer fertility than New Zealand Holstein-Friesians on pasture-based seasonal calving systems (Harris & Kolver, 2001). The present study sought to determine the effect of strain of Holstein-Friesian (HF) …

Phenotype X Herbage Allowance Interactions In Reproduction Of First Calf Heifers Grazing Semiarid Rangeland, J. W. Holloway, B. G. Warrington, M. K. Owens

IGC Proceedings (1977-2023)

Cattle are differentially adapted to nutritional environments. The most sensitive measure of adaptation is reproduction of first-calf heifers. We studied the role of maturation rate and milk production on reproductive performance of first-calf heifers allowed different levels of herbage in semiarid rangeland.

The Impact Of The Level Of Feed-On-Offer Available To Merino Ewes During Winter-Spring On The Wool Production Of Their Progeny As Adults, Chris Oldham, M. Ferguson, B. Paganoni, A. Thompson, G. Kearney, M. A. Van Burgel

IGC Proceedings (1977-2023)

New opportunities for developing optimum ewe management systems, based on achieving liveweight and body condition score (CS) targets at critical stages of the reproductive cycle, have emerged from the acceptance that nutrition during pregnancy can have substantial impacts on the lifetime wool performance of the progeny (Kelly et al,. 1996). However, most studies of the impacts of nutrition on foetal growth and development tended to focus on late pregnancy and have also only considered extreme nutritional regimes often outside the boundaries of commercial reality. Hence, the Lifetime Wool team (Thompson & Oldham, 2004) conducted dose-response experiments to determine the …

Effects Of Forage Chicory (Cichorium Intybus) On Farmed Deer Growth And Internal Parasitism, S. O. Hoskin, P. R. Wilson, W. E. Pomroy, T. N. Barry

IGC Proceedings (1977-2023)

Internal parasitism (particularly lungworm - Dictyocaulus sp) significantly limits post-weaning growth of deer. Endoparasite control using anthelmintics may be unsustainable, due to the increasing risk of anthelmintic resistance and the risk or perception of chemical residues in animal products. Chicory has a high feeding value and contains sesquiterpene lactones and low levels of condensed tannins, both with anti-parasitic activity (Molan et al., 2003). Grazing chicory during autumn may reduce the requirement for anthelmintic treatment of young deer compared with grazing ryegrass-based pasture (Hoskin et al., 1999). The objective of this study was to investigate the effect of withholding …

Oxygen Insufflation Through The Bronchoscope Channel For Sedation-Induced Hypoxia: Safe And Effective., Wissam Abouzgheib, Henry Miller, Thaddeus Bartter

Moving Forward By Looking Back: How Family Firms Create Competitive Advantage By Embracing Their History, Adam Goldman

Dissertations

Family businesses are the engine that drives the United States economy. While extensive implications have been made in the literature about the advantages or disadvantages of family-owned businesses compared to non-family-owned businesses, the focus of this study was to show how small to medium-sized family-owned firms (FF SMEs) based in the United States can use their unique history to create a competitive advantage. Drawing on imprint theory and the resource-based view (RBV), this history-informed study helped identify the impact that founder imprints, business traditions, and storytelling have on the business performance of FF SMEs. Using quantitative methods, the findings of …

Effects Of Caregiver Education On Emotional Regulation In Foster And Adopted Children, Cassie Lorraine Ice

MOT Student Capstones

There is a large demographic of American children that are in foster care or have been adopted. These children experience occurrences of adversity than children living with their biological families, including issues such as high conflict, housing instability, family isolation, abuse and neglect, and inadequate attachments with caregivers. The trauma from these factors affects the child's emotional regulation skills, leading to deficits in their social, emotional, mental, and physical well-being. Caregivers of children with emotional regulation dysfunction often feel ill-equipped to handle their child's behaviors and emotional disturbances. Caregivers often report a poor mental state, affecting time management skills, daily …

Climatic Impact Of Cross-Timber Production And Ecosystem Services On Profit Efficiency, Brian Sancewich, Iryna Mcdonald

SACAD: Scholarly Activities

The Cross-Timbers is a forested region that stretches from southern Kansas to central Oklahoma and into Texas. As an essential transitional ecotone between the eastern forest and Great Plains grassland biomes, this region is crucial for maintaining biological diversity. Much of this land is not actively managed for the critical ecosystem services that benefit people living in the region. The Cross-Timbers face threats from natural and anthropogenic factors, including climate variability. The lack of proper forest management (prescribed fires and thinning’s) has resulted in a reduction of wildlife habitats and water availability, and an increased risk of wildfires surrounding human …

From Daimones To Demons: Exorcisms And Cultural Constructions Of The Demonic In Late Antique Egypt, Madeleine Gulbransen

Departmental Honors & Graduate Capstone Projects

Christian conceptions of demonic forces and possession in Late Antique Egypt were heavily shaped by pre-existing Greek, Egyptian, and Jewish traditions. The syncretic nature of Christianization facilitated an integration of local traditions with new beliefs. A process of demonization occurred as pre-existing views of daimones from the Underworld were transformed from morally ambiguous beings into inherently evil figures. Demons and exorcism rituals served important anthropological functions as they revealed the underlying social conflicts that arose as Christianity spread and changed earlier traditions. This study focuses on magical texts, amulets, and early Christian literature to analyze the effects of Christianization on …

Afrikaans Taboo Words: Offensiveness Ranking And Reflections In Usage, Rebecca Brenkman

Theses and Dissertations

This thesis analyzes the offensiveness of Afrikaans taboo words gathered from an online survey and cross-compares it to grammatical constructions and functionality as displayed in an Afrikaans corpus. Culturally speaking, Afrikaans has a rich history of taboo terminology, especially in the racial category. The historical importance of taboo terms aids in understanding the evolution of the offensiveness of terms, especially as influenced by factors such as politics, attitude shifts, younger generations, etc. Results from the online survey focused primarily on the White Afrikaans-speaking population, as minimal responses were gathered from other ethnic groups. Additional findings from the survey indicated that …

Lysosomal Lipid Peroxidation Regulates Tumor Immunity, Monika Bhardwaj, Jennifer J Lee, Amanda M Versace, Sandra L Harper, Aaron R Goldman, Mary Ann S Crissey, Vaibhav Jain, Mahendra Pal Singh, Megane Vernon, Andrew E. Aplin, Seokwoo Lee, Masao Morita, Jeffrey D Winkler, Qin Liu, David W Speicher, Ravi K Amaravadi

Lysosomal inhibition elicited by palmitoyl-protein thioesterase 1 (PPT1) inhibitors such as DC661 can produce cell death, but the mechanism for this is not completely understood. Programmed cell death pathways (autophagy, apoptosis, necroptosis, ferroptosis, and pyroptosis) were not required to achieve the cytotoxic effect of DC661. Inhibition of cathepsins, or iron or calcium chelation, did not rescue DC661-induced cytotoxicity. PPT1 inhibition induced lysosomal lipid peroxidation (LLP), which led to lysosomal membrane permeabilization and cell death that could be reversed by the antioxidant N-acetylcysteine (NAC) but not by other lipid peroxidation antioxidants. The lysosomal cysteine transporter MFSD12 was required for intralysosomal transport …

Climate Change, Site Formation, And Indigenous Use Of Coastlines In Barbuda, Isabel C. Rivera-Collazo, Sophia Perdikaris

School of Global Integrative Studies: Faculty Publications

This article explores the landscape dynamics at the island of Barbuda in the context of changing climate to understand (1) the environmental setting of indigenous settlements; (2) the impacts of current coastal processes; and (3) the potential threats moving forward toward increasing pressure of climate change. Focusing on the site of Seaview, on the east coast of Barbuda, we use geoarchaeological methods to reconstruct the ancient geomorphological setting, investigate changes post-abandonment, and identify the hazards faced under future sea-level projections. Our study shows that (1) sea level stabilization after the Mid-Holocene allowed the formation of coral reefs, seagrass beds and …
