Mama Nyani: A Study Of The Correlation Of Behaviors And Habitat In Papio Anubis, Madison Beran

Independent Study Project (ISP) Collection

As the population in Tanzania continues to grow more people are in search of jobs. In Northern Tanzania a village named Mto Wa Mbu is conveniently located directly adjacent to Lake Manyara National Park. With its good location and weather for crops, many people have moved there in hopes to earn some money from the 1 million tourists that visit Tanzania per year. As more people move to Mto Wa Mbu the pressure between animals and the people has increased. With the national park directly across the street from housing both animals and people can easily access each other’s homes. …

Arizona’s vulnerable populations are struggling on a daily basis but usually do so in silence, undetected by traditional radar and rankings, often unaware themselves of their high risk for being pushed or pulled into a full crisis. Ineligible for financial assistance under strict eligibility guidelines, they don’t qualify as poor because vulnerable populations are not yet in full crisis. To be clear, this report is not about the “poor,” at least not in the limited sense of the word. It is about our underemployed wage earners, our single-parent households, our deployed or returning military members, our under-educated and unskilled workforce, …

Genetic Risk Of Progression To Type 2 Diabetes And Response To Intensive Lifestyle Or Metformin In Prediabetic Women With And Without A History Of Gestational Diabetes Mellitus., Shannon D Sullivan, Kathleen A. Jablonski, Jose C Florez, Dana Dabelea, Paul W Franks, Sam Dagogo-Jack, Catherine Kim, William C Knowler, Costas A Christophi, Robert Ratner, Diabetes Prevention Program Research Group.

GW Biostatistics Center

OBJECTIVE The Diabetes Prevention Program (DPP) trial investigated rates of progression to diabetes among adults with prediabetes randomized to treatment with placebo, metformin, or intensive lifestyle intervention. Among women in the DPP, diabetes risk reduction with metformin was greater in women with prior gestational diabetes mellitus (GDM) compared with women without GDM but with one or more previous live births.

RESEARCH DESIGN AND METHODS We asked if genetic variability could account for these differences by comparing β-cell function and genetic risk scores (GRS), calculated from 34 diabetes-associated loci, between women with and without histories of GDM.

RESULTS β-Cell function was …

Increasing Dry Cow And Bred Heifer Performance With Environmental Management, Stephen F. Higgins, Kylie Schmidt

Agriculture and Natural Resources Publications

Producing high-quality milk is a primary concern of dairy farmers, which is why the production herd often receives more attention than the dry cows and bred heifers. However, it is important that dairy producers not lose sight of the great value that their dry cows and bred heifers hold: the future of the milking herd. Environmental management practices such as rotational grazing, heavy-use area pads for feeding and watering, and shelter can be used to increase close-up cows’ future performance by preventing mastitis and other health disorders such as lameness.

Soybean Nutrient Management In Kentucky, Edwin L. Ritchey, Chad Lee, Carrie Ann Knott, John H. Grove

Agriculture and Natural Resources Publications

Soybean grows best on fertile soils. For decades, the University of Kentucky has conducted field studies to establish the relationship between soil nutrient supplies and soybean yield. Adequate soil fertility must be present so that yields are not limited. Soybean removes a large amount of nutrients in the seed relative to other annual crops. For each bushel of soybean produced, 3 lb N, 0.7 lb P₂O₅, and 1.1 lb K₂O will be removed in the seed, but considerably more is required to supply the leaves, stems and pods that are not removed during harvest …

Such applications can help provide situational awareness during an emergency, improve preparedness, and assist during the rebuilding/recovery phase of a …

Study Of The Sustainbility Issues Of Food Production Using Vertical Farm Methods In An Urban Environment Within The State Of Indiana, Victor Mendez Perez

Open Access Theses

There are several problems around the globe related to water scarcity, energy shortages, deforestation and loss of fertile land, and food security. Climate change is making environmental and social issues arise. Issues such as, changes in the agricultural landscape, increasing population (9 billion is the expected population for 2040), rising food borne illnesses, scarcity of drinking water, and more crop failure due to plant pathogens and insect pests, among other factors make this study specially significant. Vertical farming could be a potencial solution to some of these problems.

Due to these problems the present thesis analyzed vertical farming as a …

Deforestation Of Cloud Forest In The Central Highlands Of Guatemala: Soil Erosion And Sustainability Implications For Q'Eqchi' Maya Communities, Ian Christopher Pope

Open Access Theses

Understanding the nexus between deforestation, food production, land degradation, and culture contributes knowledge that is useful for development practitioners working to enhance conservation and food security. Documenting deforestation and soil erosion in the Sierra Yalijux and Sierra Sacranix in the Central Highlands of Guatemala adds new knowledge about the rates and dynamics of deforestation and land degradation in areas with unique and sensitive cloud forest ecosystems. It also suggests possible areas of emphasis for efforts targeted at combining cloud forest conservation with sustainability for indigenous Q'eqchi' communities. In addition, this work contributes to a small but growing body of literature …

Oxidative Stress In Algae: Method Development And Effects Of Temperature On Antioxidant Nuclear Signaling Compounds, Md Noman Siddiqui

Open Access Theses

Non-enzymatic antioxidants neutralize the oxidative stress through scavenging reactive oxygen species. The structural complexity of non-enzymatic nuclear signaling antioxidants poses are more challenges for traditional quantitative analysis as these compounds have multiple forms and structurally diverse than proteins and therefore, challenge traditional analytical techniques. Current analytical methods cannot distinguish the carotenoids, and vitamin A and D metabolites within a single sample. To find an appropriate method to measure all the nuclear signaling compounds in algae, Isochrysis sp. , under thermal stress, HPLC/ESI-MS and HPLC /APPI-MS was used. Standards of those compounds were run by QQQ HPLC/ ESI-MS and HPLC /APPI-MS …

Prepubertal Exposure To Arsenic(Iii) Suppresses Circulating Insulin-Like Growth Factor-1 (Igf-1) Delaying Sexual Maturation In Female Rats, Michael P. Reilly, James C. Saca, Alina Hamilton, Rene F. Solano, Jesse R. Rivera, Wendy Innis-Whitehouse, Jason Parsons, Robert K. Dearth

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Arsenic (As) is a prevalent environmental toxin readily accessible for human consumption and has been identified as an endocrine disruptor. However, it is not known what impact As has on female sexual maturation. Therefore, in the present study, we investigated the effects of prepubertal exposure on mammary gland development and pubertal onset in female rats. Results showed that prepubertal exposure to 10 mg/kg of arsenite (As(III)) delayed vaginal opening (VO) and prepubertal mammary gland maturation. We determined that As accumulates in the liver, disrupts hepatocyte function and suppresses serum levels of the puberty related hormone insulin-like growth factor 1 (IGF-1) …

Uncertainties In Life Cycle Greenhouse Gas Emissions From U.S. Beef Cattle, Quentin M. Dudley, Adam Liska, Andrea K. Watson, Galen E. Erickson

Adam Liska Papers

Beef cattle feedlots are estimated to contribute 26% of U.S. agricultural greenhouse gas (GHG) emissions, and future climate change policy could target reducing these emissions. Life cycle assessment (LCA) of GHG emissions from U.S. grain-fed beef cattle was conducted based on industry statistics and previous studies to identify the main sources of uncertainty in these estimations. Uncertainty associated with GHG emissions from indirect land use change, pasture soil emissions (e.g. soil carbon sequestration), enteric fermentation from cattle on pasture, and methane emissions from feedlot manure, respectively, contributed the most variability to life cycle GHG emissions from beef production. Feeding of …

School of Geosciences Faculty and Staff Publications

Powdery mildew is one of the most serious diseases that have a significant impact on the production of winter wheat. As an effective alternative to traditional sampling methods, remote sensing can be a useful tool in disease detection. This study attempted to use multi-temporal moderate resolution satellite-based data of surface reflectances in blue (B), green (G), red (R) and near infrared (NIR) bands from HJ-CCD (CCD sensor on Huanjing satellite) to monitor disease at a regional scale. In a suburban area in Beijing, China, an extensive field campaign for disease intensity survey was conducted at key growth stages of winter …

Temperature And Relative Humidity Effects On Water Loss And Hemolymph Osmolality Of Littoraria Angulifera (Lamarck, 1822), Phillip J. Rose

Theses and Dissertations - UTB/UTPA

Desiccation stress is considered to be one of the more significant determining factors that influence how organisms are distributed in the marine littoral. Gastropods living above the high tide mark, referred to as eulittoral fringe gastropods are not wetted as regularly and face unpredictable and prolonged periods of emersion. Consequently, adaptations displayed by eulittoral fringe gastropods are aimed at minimizing water loss and surviving prolonged periods of desiccation stress. Littoraria angulifera, is a tropically distributed marine eulittoral fringe gastropod. Because L. angulifera spends a majority of its time emersed there was interest in studying how the weight loss and hemolymph …

Determination Of The Ecological Condition Of Benthic Communities Affected By Polycyclic Aromatic Hydrocarbons In The Elizabeth River, Chesapeake Bay, Usa, Adam M. Webb

Biological Sciences Theses & Dissertations

The Southern Branch of the Elizabeth River, a tributary of Chesapeake Bay, has historically been polluted with hydrocarbon based industrial by-products. My study compared benthic community condition from two locations in the Southern Branch: the subtidal region near Money Point, historically affected by pollution of polycyclic aromatic hydrocarbons (PAHs), to a subtidal region near Blows Creek on the opposite shore that is putatively designated as unimpacted by P AH contamination. Samples from both study sites in the Southern Branch were compared to the benthic community condition of samples from the same habitat type designations collected as part of the Chesapeake …

Influence Of Diet On Element Incorporation In The Shells Of Two Bivalve Molluscs: Argopecten Irradians Concentricus And Mercenaria Mercenaria, William Noland Elsaesser

USF Tampa Graduate Theses and Dissertations

Recently, biogenic carbonates have received much attention as potential proxies of environmental change; however, a major pathway of elemental incorporation is often overlooked when making interpretations or designing experiments. This research experimentally examines the influence of diet on elemental composition in juvenile shells of the bay scallop, Argopecten irradians concentricus, and the northern quahog, Mercenaria mercenaria.

Exploratory trials were conducted using Argopecten irradians concentricus juveniles fed different algal diets: Isochrysis, Chaetoceros, Pavlova, Tetraselmis, or a mix of all four in a 2:1:2:2 ratio. No differences between the left and right valves were revealed, thus, subsequent analysis of the dietary influence …

Sustainable Energy And Nutrient Recovery From Swine Waste, Adib Amini

USF Tampa Graduate Theses and Dissertations

Swine production represents approximately 40% of the world's meat production, and swine wastes contain high concentrations of organic matter, nitrogen (N) and phosphorus (P). Swine production is intensifying as meat demand increases and concentrated animal feeding operations (CAFOs) are becoming increasingly common, making it difficult to treat the waste generated. A system for holistic treatment of swine waste produced in CAFOs was investigated in this study that sustainably generates energy and recovers N and P as saleable fertilizers. The system uses anaerobic digestion (AD) for methane production and solids stabilization, followed by precipitation of struvite (MgNH4PO4*6H2O) and recovery of N …

Isolation Of Antibacterial Compounds From Artemisia Californica, Jae Eun Min

Seaver College Research And Scholarly Achievement Symposium

The Chumash Native Americans of Southern California have well-documented traditions of using plants for medicinal purposes. If a specific plant has traditionally been used by Chumash for the treatment of cuts, wounds and infections, it may contain chemicals with anti-bacterial properties. One plant that fits these criteria is Artemisia californica (coastal sage). Because of the widespread use of antibiotics over the past sixty years bacteria are evolving greater resistance to known antibiotics, but unfortunately the rate of antibiotic discovery has diminished during the past twenty years. Therefore, novel and effective antibiotics are essential for the continued treatment of bacterial infections. …

Fossil Vertebrates From The Basal Lincoln Limestone Of The Greenhorn Limestone (Upper Cretaceous) In Southeastern Colorado, Christopher Gallardo

DePaul Discoveries

The basal Lincoln Limestone is a 95-million-year-old fossiliferous rock layer deposited under the Late Cretaceous Western Interior Seaway in North America. Over 4,500 identifiable vertebrate remains were collected from the stratigraphic horizon at a new fossil locality referred to as the Table Mesa locality in southeastern Colorado. Twenty-nine marine vertebrate taxa were identified comprising 13 chondrichthyans (cartilaginous fishes), 14 osteichthyans (bony fishes), and two squamate reptiles (lizards). These remains were then sorted according to their taxonomic similarities for faunal comparisons with other basal Lincoln Limestone localities. Proportions of common taxa at the Table Mesa locality are similar to another basal …

Predicting Human Behavior, Tamara Kneese

Media Studies

Countless highly accurate predictions can be made from trace data, with varying degrees of personal or societal consequence (e.g., search engines predict hospital admission, gaming companies can predict compulsive gambling problems, government agencies predict criminal activity). Predicting human behavior can be both hugely beneficial and deeply problematic depending on the context. What kinds of predictive privacy harms are emerging? And what are the implications for systems of oversight and due process protections? For example, what are the implications for employment, health care and policing when predictive models are involved? How should varied organizations address what they can predict?

Design, Synthesis, And Biological Evaluation Of Non-Symmetric Smal, Himabindu Anumala

Master's Theses and Doctoral Dissertations

Plasminogen activator inhibitor-1 (PAI-1) is a member of the serpin family of proteins, a primary inhibitor of both tissue-type and urokinase-type plasminogen activators in plasma, and is a well-established risk factor in various disease conditions. Increased levels of active PAI-1 in plasma are correlated with the development of atherosclerosis, diabetes, stroke, and other maladies. In the present study, we describe the synthesis of two new series of compounds that aim to reduce physiologically active PAI-1 levels. These molecules are related to a series of bis-arylsulfonimides and arylsulfonamides connected by short linking diamines, and to a series of hydrazine-based analogues. These …

In this study, we used a cross-sectional study design to examine the relationship between the calcium intake and risk factors for CVD among obese adults by using continuous waves of National Health and Nutrition Examination Survey (NHANES) data 1999-2010. The association between calcium intake and risk factors of CVD (hypertension, total cholesterol, HDL, glycohemoglobin), CRP, albuminuria) is assessed among obese adults in USA. The incidence of Cardiovascular Disease (CVD) is high among obese people. The potential effects of inadequate calcium intake on CVD are receiving increased epidemiologic attention. Understanding the association between risk factors for CVD and calcium intake among …

A Novel Three Serum Phospholipid Panel Differentiates Normal Individuals From Those With Prostate Cancer, Nima Patel, Robert L. Vogel, Kumar Chandra-Kuntal, Wayne Glasgow, Uddhav Kelavkar

Biostatistics: Faculty Publications

Background: The results of prostate specific antigen (PSA) and digital rectal examination (DRE) screenings lead to both under and over treatment of prostate cancer (PCa). As such, there is an urgent need for the identification and evaluation of new markers for early diagnosis and disease prognosis. Studies have shown a link between PCa, lipids and lipid metabolism. Therefore, the aim of this study was to examine the concentrations and distribution of serum lipids in patients with PCa as compared with serum from controls.

Method: Using Electrospray ionization mass spectrometry (ESI-MS/MS) lipid profiling, we analyzed serum phospholipids from age-matched subjects who …
