Dry Matter Intake By Beef Steers On Piatã Palisadegrass (Brachiaria Brizantha Cv. Brs Piatã) Pasture, Denise B. Montagner, Valéria P. B. Euclides, Teresa C. M. Genro, Nayana N. Nantes

IGC Proceedings (1977-2023)

Beef production in Brazil is primarily based on tropical pastures and 85% of these pastures are Brachiaria brizantha cv. Marandu. Such a monoculture could prove disastrous if some pest or disease emerged. With the goal of further diversifying pastures and contributing to the sustainability of the pasture production system, B. brizantha cv. BRS Piatã was released by the Brazilian Agricultural Research Corporation (Embrapa). Little is known about the characteristics of this cultivar in relation to grazing management and plant-animal interactions. Dry matter (DM) intake by grazing animals is influenced by the structural characteristics of tropical grasses (Stobbs 1973, 1975), and …

Agronomic Evaluation Of 324 Intraspecific Hybrids Of Brachiaria Decumbens In Brazil, Rogério G. Mateus, Sanzio C. L. Barrios, Ulisses J. De Figueiredo, Cacilda B. Valle

IGC Proceedings (1977-2023)

Brachiaria decumbens cv. Basilisk is the most planted pasture grass in the tropics owing to its adaptation to poor and acid soils, typical of the tropics, plus good animal performance. This cultivar was responsible for a radical change of scenario in central Brazil in the early 1970s and is the only cultivar available commercially. Efforts to breed this species have been recent, as the successful somatic chromosome duplication of sexually reproducing diploid plants of B. decumbens was accomplished only in 2009 (Simioni and Valle 2009). Subsequently, intraspecific crosses with natural apomictic tetraploid accessions were carried out. Breeding is needed since …

Effect Of Season And Year Of Evaluation In The Selection Of Brachiaria Humidicola Hybrids, Ulisses J. De Figueiredo, José A. R. Nunes, Cacilda B. Valle, Sanzio C. L. Barrios, Geovani F. Alves

IGC Proceedings (1977-2023)

Brachiaria humidicola is well adapted to infertile and acid soils with poor drainage or temporary flooding (Keller-Grein et al. 1996). It is widely used in Brazil in wetlands and areas of marginal land characterised by waterlogged soils. During the evaluation stages of the breeding program of this species, genotypes are generally tested using consecutive cuts within different seasons for at least 2 years. The ‘Cerrado’ region, where most animal production takes place in Brazil, has 2 well defined seasons: spring-summer with warm weather and rain; and autumn-winter with cooler, dry weather. Thus, owing to environmental variation, especially related to …

Development, Isolation And Characterisation Of A New Non-Virulent Mimosine-Degrading Klebsiella Pneumoniae Strain From The Rumen Liquor Of German Steers By Using Ibt-Goettinger Bioreactor, Aung Aung, U. Ter Meulen, F. Gessler, H. Böhnel

IGC Proceedings (1977-2023)

The tropical legume Leucaena leucocephala (leucaena) has many uses, including: a potential source of firewood and timber; for soil erosion control (Dijkman 1950); to provide shade; to enhance soil fertility; and as a nutritious forage for animal feed (Ruskin 1977). It is widely used as forage for cattle in tropical agriculture (Shelton 1998). In Myanmar, leucaena is used as a protein source in urea-molasses multi-nutrient blocks for ruminants (Ni Ni Maw et al. 2004). However, the use of leucaena as ruminant feed is not without problems, because it contains mimosine, a toxic anti-nutritional factor limiting its use as animal …

Brs Paiaguás: A New Brachiaria (Urochloa) Cultivar For Tropical Pastures In Brazil, Cacilda B. Valle, Valéria P. B. Euclides, Denise B. Montagner, José R. Valério, Celso D. Fernandes, Manuel C. M. Macedo, Jaqueline R. Verzignassi, Luis A. Machado

IGC Proceedings (1977-2023)

Approximately half the world’s beef is produced in the tropics and subtropics, almost exclusively on pasture. While the world production of beef and veal increased 91% over the past 40 years, the increase in the tropics was 200%. Brazil has today the largest commercial cattle herd in the world (about 190 M head) and is the world's largest exporter of beef. The area of cultivated pasture increased from 30 to 100 Mha between 1970 and 1995 (IBGE 2006). This area has now stabilised or decreased despite the increase in beef production, which reflects the gain in area productivity. Part of …

Selecting New Brachiaria Humidicola Hybrids For Western Brazilian Amazon, Giselle M. L. De Assis, Cacilda B. Valle, Carlos M. S. De Andrade, Judson F. Valentim

IGC Proceedings (1977-2023)

Brachiaria humidicola is a perennial and stoloniferous forage grass, with excellent adaptation to infertile soils and waterlogging. Producers in northern Brazil have become interested in this species, especially after the degradation of large areas of lowly permeable soils sown with B. brizantha cv. Marandu, which is highly intolerant of soil waterlogging (Andrade and Valentim 2006). However, since only 3 cultivars of B. humidicola are registered in Brazil (Mapa 2013), there is a need to develop new cultivars adapted to the range of environmental conditions experienced. Recently, Embrapa Beef Cattle obtained intraspecific hybrids of B. humidicola that need to be evaluated …

Brs Mandobi: A New Forage Peanut Cultivar Propagated By Seeds For The Tropics, Giselle M. L. De Assis, Judson F. Valentim, Carlos M. S. De Andrade

IGC Proceedings (1977-2023)

Forage peanut (Arachis pintoi) is a forage legume of relatively recent use in beef and dairy cattle feeding. Although it is native exclusively to Brazil, the first cultivar, Amarillo, was released in Australia in 1987. Forage peanut has a great number of favourable attributes for establishing grass-legume mixtures, which guarantee the persistence and high yields of high quality forage in cultivated pastures. Therefore, studies with this species have intensified in many tropical regions of the world (Assis and Valentim 2009). In the state of Acre, western Brazilian Amazon, 137,000 ha are cultivated with forage peanut, cv. Belmonte, benefiting …

Sample Size Considerations For Clustered And Correlated Outcomes In Clinical Research, Xiaohan Xu

Statistical Science Theses and Dissertations

In this dissertation, we investigate sample size calculations for three different study designs: stratified cluster randomization trials (CRTs), paired experimental designs and paired cluster experimental designs.

Stratified CRTs have been frequently employed in clinical and healthcare research. Comparing with simple randomized CRTs, stratified CRTs reduce the imbalance of baseline prognostic factors among different intervention groups. Clusters are often naturally formed with random sizes in CRTs. With varying cluster size, commonly used ad hoc approaches ignore the variability in cluster size, which may underestimate (overestimate) the required number of clusters for each group per stratum and lead to underpowered (overpowered) clinical …

Women’S Resilience In Preserving Family Life Following An Earthquake In North Lombok Regency, West Nusa Tenggara, Indonesia, Tuti Budirahayu, Anis Farida, Sughmita Maslacha Amala S.

Journal of International Women's Studies

The earthquake in Lombok, West Nusa Tenggara, in August 2018 not only damaged the environment and the area around the epicenter but also shook public order. The shaking of economic and social infrastructure is being paid for by unpreparedness in facing disasters, and this is compounded by the mental deterioration of the community due to the loss of family members. This study aims to describe women's abilities during the aftermath of the disaster, and their efforts to overcome economic and social problems within their families. We also observed women's collective efforts as a way to eliminate trauma (trauma healing). This …

Gender, Religion And Patriarchy: The Educational Discrimination Of Coastal Madurese Women, East Java, Sudarso Sudarso, Phillipus Edy Keban, Siti Mas’Udah

Journal of International Women's Studies

One of the educational development problems is the gap in the quality of education between regions and community groups, as well as gender. This article has examined gender, religion, patriarchy and the educational discrimination faced by coastal women who are a part of the Madura culture in East Java. This study employed a qualitative approach by interviewing 70 informants who consisted of school dropouts, the parents of daughters who had dropped out, teachers, and community leaders. This study found there to be several key findings. In the Madura culture, the concept of gender for women is always associated with the …

Long-Lasting Insecticide Netting For Protecting Tree Stems From Attack By Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae), Christopher M. Ranger, Christopher T. Werle, Peter B. Schultz, Karla M. Addesso, Jason B. Oliver, Michael E. Reding

Agricultural and Environmental Sciences Faculty Research

Ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) are destructive wood-boring insects of horticultural trees. We evaluated long-lasting insecticide netting for protecting stems against ambrosia beetles. Container-grown eastern redbud, Cercis canadensis, trees were flood-stressed to induce ambrosia beetle attacks, and deltamethrin-treated netting was wrapped from the base of the stem vertically to the branch junction. Trees were deployed under field conditions in Ohio, Virginia, Tennessee, and Mississippi with the following treatments: (1) flooded tree; (2) flooded tree with untreated netting; (3) flooded tree with treated ‘standard mesh’ netting of 24 holes/cm²; (4) flooded tree with treated ‘fine mesh’ netting of 28 …

Food Choice Reform: Shifting American Culture Toward Sustainable Diets, Colleen Mccarthy

Student Theses 2015-Present

Excessive meat consumption is associated with a wide range of environmental problems. Reducing meat consumption has been recognized as one of the most efficient ways to decrease one’s ecological footprint, yet meat consumption is still on the rise and many are not willing to make changes to their diets to include less meat. This paper discusses the problem of America’s continued and rising overconsumption of meat, with the end goal of developing and concluding which strategies are most effective at shifting American culture toward sustainable diets. Chapter 1 gives an overview of why a reduction in meat consumption is necessary …

Characterization Of Phenolic Acids For Incorporation Into Shape Memory Polymer Foams, Jingyi Liu

Theses - ALL

Shape memory polymer (SMP) foams provide a promising new option for hemorrhage control on the battlefield; however, they lack a mechanism to control wound infections that can delay healing processes. Adding phenolic acids (PAs) into SMP foams provides a natural, non-drug option for incorporations of antioxidant and antimicrobial functionalities that may promote healing. However, PAs lack a systemic characterization of their structure/property relationships, and their chemical incorporation into SMP foams may alter their efficacy. In this work, a library of PAs was screened in terms of antioxidant and antimicrobial properties to provide a full understanding of how their structure affects …

Precarity Beyond Food: How The Closure Of An Independent Grocery Store Shed Light On The Limitations Of Food Access Efforts In Syracuse, New York, Katherine Louisa Ravene Mott

Theses - ALL

On September 11, 2017, the owner of an independent grocery store in Syracuse, New York’s Near Westside neighborhood announced that the store would close within the month. The Near Westside is often characterized by its high levels of concentrated poverty for African American and Hispanic neighborhood residents. Nojaim Brothers Supermarket opened in 1919 and persisted for 97 years amidst an unfavorable political and economic landscape marked by the creation of both chain grocery stores and supermarkets as well as the effects of urban renewal and disinvestment. I argue that Nojaim’s endurance can be attributed to the embeddedness of the grocery …

Fighting Food Insecurity For Nyc Children And Youth: Urban Agriculture And Food Justice, Devin C. O'Mara

Student Theses 2015-Present

The positive benefits of urban agriculture go beyond just providing fresh and healthy food to metropolitan areas. As the practice of urban farming has become increasingly more popular over the last decade or so, it has proven to develop community relations and aide with metropolitan and global issues such as poverty. Children and teens especially benefit from urban agriculture, specifically those that comes from underprivileged homes that may not have the resources to obtain fresh food every day. A shocking number of kids can go hungry every day due to lack of available food. Many children that live in metropolitan …

Breaking Ground On New Agricultural Models: Industrial Agriculture And The Local Food Movement, Elizabeth Nealon

Student Theses 2015-Present

This paper discusses and examines the longstanding issues surrounding industrial food production as it currently exists and the various ways that purpose-driven enterprises and environmentally-conscious consumers in the United States have been able to steer food production in a more sustainable direction. Over the course of the technological revolution, people living in metropolitan areas have become so distanced from farms and the processes of food production that many are ignorant of the realities of the food industry. Chapter 1 addresses these issues by presenting quantitative data that lays out a timeline of the evolution of the food and agriculture industry …

The Effects Of Replacement Of Fish Meal Protein With A Mixture Of Poultry By-Product Meal, Fish Silage And Fish Protein Hydrolysate On The Growth Performances Of Asian Sea Bass (Lates Calcarifer), Yu-Cong Hong, Angela Chien, Shyn-Shin Sheen

Journal of Marine Science and Technology–Taiwan

This feeding trial was conducted to investigate the effects of replacement of dietary fishmeal (FM) with a mixture of poultry by-product meal (PBM), fish silage (FS) and fish protein hydrolysate (FPH) on the growth performances of the Asian sea bass Lates calcarifer. Five isonitrogenous (46% crude protein) and isolipidic (12% crude lipid) diets were formulated to replace 0 (CON), 25 (FM 25), 50 (FM 50), 75 (FM 75) and 100% (FM 100) of fishmeal protein with the protein mixture (78% PBM, 11% FS, and 11% FPH). One additional diet, namely POM was designed to completely replace FM protein with PBM. …

Microbial Communities In Human Milk Relate To Measures Of Maternal Weight, Sara N. Lundgren, Juliette C. Madan, Margaret R. Karagas, Hilary G. Morrison, Anne G. Hoen, Brock C. Christensen

Dartmouth Scholarship

The process of breastfeeding exposes infants to bioactive substances including a diversity of bacteria from breast milk as well as maternal skin. Knowledge of the character of and variation in these microbial communities, as well as the factors that influence them, is limited. We aimed to identify profiles of breastfeeding-associated microbial communities and their association with maternal and infant factors. Bilateral milk samples were collected from women in the New Hampshire Birth Cohort Study at approximately 6 weeks postpartum without sterilization of the skin in order to capture the infant-relevant exposure. We sequenced the V4–V5 hypervariable region of the bacterial …

A Transcriptomic Exploration Of Hawaiian Drosophilid Development And Evolution, Madeline M. Chenevert

LSU New Orleans Theses and Dissertations

One in four known species of fruit flies inhabit the Hawaiian Islands. From a small number of colonizing flies, a wide range of species evolved, some of which managed to reverse-colonize other continental environments. In order to explore the developmental pathways, which separate the Hawaiian Drosophila proper and the Scaptomyza group that contains reverse-colonized species, the transcriptomes of two better-known species in each group, Scaptomyza anomala and Drosophila grimshawi, were analyzed to find changes in gene expression between the two groups. This study describes a novel transcriptome for S. anomala studies as well as unusual changes in gene expression …

Role Of Astrocyte-Derived Extracellular Vesicles In Neuroinflammation Mediated By Drug Abuse, Ke Liao

Theses & Dissertations

Neuronal damage and neuroinflammation is a hallmark feature of HIV-associated neurological disorders (HANDs). Opioids abuse accelerates the incidence and progression of HAND; however, the mechanisms underlying the potentiation of neuropathogenesis by these drugs remain elusive. Extracellular vesicles (EVs) are essential conduits in HIV and drug abuse-mediated synaptodendritic injury and neuroinflammation. Findings from our group have demonstrated that astrocyte-derived EV (ADEV)-miRNA-29b mediates HIV Tat and morphine-induced neuronal injury, thus underscoring the importance of such interactions in NeuroHIV.

Besides, HIV Tat and morphine-mediated synaptodendritic injury via ADEVs, we are also interested in whether ADEVs contributes to neuroinflammation. Microglia are critical players in …

Acclimation, Long-Term Repeatability, And Phenotypic Correlations Of Aerobic Metabolic Traits In The Gulf Killifish, Fundulus Grandis, Jessica E. Reemeyer

LSU New Orleans Theses and Dissertations

This research examined the effects of acclimation to lowered salinity, elevated temperature, and hypoxia on aerobic metabolism of the Gulf killifish, Fundulus grandis, a common estuarine resident of the Gulf of Mexico. Standard metabolic rate (SMR), maximum metabolic rate (MMR), absolute aerobic scope (AAS), and critical oxygen tension (P_crit) were each influenced by one or more acclimation treatments. Assessing the consistency of these traits measured in the same individuals over time, all were found to be significantly repeatable with no indication that the repeatability of any traits was affected by acclimation conditions. Significant correlations were found between …

Lifestyle Management For Vestibular Disorders, Michelle Pock

Student Capstone Papers

Individuals with vestibular disorders have concerns that impact lifestyle including limiting activities of daily living, limiting participation in social events, difficulty driving, and difficulty working (Cohen, 2014). Occupational therapists are able to help individuals with vestibular disorders by task analyzing symptom provoking activities, assessing the impact of symptoms on occupations, providing adaptations, and providing ways to modify environments (Gronski, Neville, Kannenberg, & Cohen, 2017). While occupational therapists are qualified to provide services to sustain and improve the occupational performance of individuals with vestibular disorders, occupational therapy is not well represented in this area particularly in addressing lifestyle components for vestibular …

Ecdysoneless, A Novel Regulator Of Ca2+ Homeostasis And Metabolism, Aniruddha Sarkar

Theses & Dissertations

The hallmarks of cancer include sustained proliferation and survival in the face of cellular stresses imposed by the oncogenic drive, as well as metabolic rewiring for tumor growth under adverse nutritional conditions. Adaptive alterations in key biochemical networks that underlie metabolic rewiring represent potential opportunities to develop new therapeutic strategies against cancer.

My thesis focuses on mammalian Ecdysoneless (ECD), a conserved homolog of the fly Ecdysoneless gene product, which engages fundamental cell biological processes of ER stress, Ca²⁺ signaling and metabolism to help sustain the oncogenic drive in tumor cells. Recent studies from our laboratory provide a clear evidence …

Weathering The Storm: Black Maternal Mortality, Resistance, And Power In Richard Wright’S “Down By The Riverside,” Zora Neale Hurston’S Their Eyes Were Watching God, And Jesmyn Ward’S Salvage The Bones, Renee Vincent

LSU New Orleans Theses and Dissertations

Representations of natural disasters in Black Southern literature identify social location as the greatest indicator of risk vulnerability. Moreover, they can expose the precarious subjectivity of the Black female reproductive body, as addressed through characters Lulu in Richard Wright’s “Down by the Riverside,” Janie in Zora Neale Hurston’s Their Eyes Were Watching God, and Jesmyn Ward’s Esch in Salvage the Bones. Together, these female characters share a legacy of social marginalization and Black female resistance that is (re)shaped through their experiences with ecological catastrophe. This thesis considers these three texts together as an ongoing testimony and as a …

The Ethical Justification Of Increasing Awareness Of Preventive Medicine Among Healthcare Professionals, Patients And The General Public In The United States, Karishma Ether Moazzam

Electronic Theses and Dissertations

While practiced for centuries, preventive medicine has received increased attention during the recent times. Preventive medicine has a distinct mission to protect, promote, and maintain health as well as to prevent diseases, disabilities, and premature deaths. It aims to fulfill its mission through the combined form of clinical intervention and health promotion. In the recent years, preventive medicine has begun to lean more towards the clinical interventions, taking away from the health promotion. This imbalance has caused preventive medicine to lose its effectiveness in fulfilling its mission. One of the leading causes for such imbalance is the lack of proper …
