Indigenous Microbial Biostimulation For Microbial Enhanced Oil Recovery Through Oil Degradation With Variation In Nutrent Concentrations, Rika Handaruni, Dea Indriani Astuti, Isty Adhitya Purwasena, Lulu Nur Afifah

Makara Journal of Science

Oil production in Indonesia has been declining since 2002, and this decline is incompatible with the high oil consumption in Indonesia. As such oil production in Indonesia should be improved. Biostimulation in microbial enhanced oil recovery involves environmental modification to stimulate microbial growth within a reservoir by adding limiting nutrients. Variation in C, N, and P concentrations injected to reservoirs can induce different responses from indigenous microbes and increase oil recovery. In this study, molasses, urea and diammonium phosphate were used as nutrients injected to a reservoir for biostimulation. Biological, physical and chemical characteristics after biostimulation were observed and bacterial …

Antibacterial And Anti-Biofilm Activities Of Culture Filtrates From Schizophyllum Commune, Coniothyrium Sp., And Fusarium Sp., Aerma Hastuty, Rahma Mairani, Keukeu Kaniawati Rosada

Bacterial infections are usually caused by biofilms that are resistant to extreme conditions. Studies have shown that fungal extracts have the potential to inhibit biofilm formation. The aim of this study was to examine the activity of several fungal culture filtrates in inhibiting bacterial growth and biofilm formation. The fungi were identified by molecular method, and the effects of different concentrations (45%, 75%, and 90%), medium pH (6, 7, and 9), temperatures (30 and 37 °C), and incubation times (24, 48, and 72 h) of the filtrates on their anti-biofilm formation properties were investigated. Anti-biofilm assay was performed using the …

Biosensor And Chemosensor Fluorophores That Contain Chalcogenide Centers, Tesla Yudhistira, Woo Hyun Lee, David G. Churchill

Makara Journal of Science

In this timely review, we discuss the important attributes of various chalcogen-containing small-molecule probes that have been synthesized in the Molecular Logic Gate Laboratory at the Korea Advanced Institute of Science and Technology. Specifically, we discuss some of the important chemical and photophysical properties of these probes, including reversibility, responsiveness (response time), cellular localization, sensitivity to analytes, selectivity (toward a specific analyte in question), and some bioavailability criteria. Chalcogenides undergo reversible redox-type reactions with reactive oxygen species (ROS). These controlled solution reactions enable a sensible and clear response as they act to immediately affect the chemical and electronic properties of …

Identification Of Planthoppers (Hemiptera: Delphacidae) Intercepted On Aquarium Plants In Florida And Elucidation Of A Potential Pathway For Exotic Aquatic And Semiaquatic Pests, Susan E. Halbert, Matthew R. Moore, Charles R. Bartlett, Jade S. Allen

Insecta Mundi

Recent shipments of aquarium plants to pet stores in five Florida counties were found to be infested with an exotic delphacid planthopper. Rearing adult males allowed identification by morphological analysis. Molecular analysis confirmed that it was the same as authoritatively identified reference specimens of the planthopper, Opiconsiva anacharsis (Fennah) (new combination) (Hemiptera: Delphacidae), first reported from Florida in 1989 and known to be established only in Broward County. The host plants, Echinodorus spp. Rich. ex Engelm. (Alismatales: Alismataceae), originally from Thailand, were sold in enclosed plastic cylinders that provided a suitable environment for maintaining the planthoppers. Attempts to trace the …

Creating A Multi-Berry Shrub Via Cross Grafting, Alexa Laurent

The Pegasus Review: UCF Undergraduate Research Journal

Grafting is a process used to physically combine two different plants together. This process allows for a scion, the branch of one plant, to be added to the rootstock, the base of another plant. Combining plants allows for more varieties of fruit to be produced in less space for fruit bearing plants and creates more opportunities for hybridization with the plants utilized. Currently, research shows that grafting is possible when two plants of the same family are used. Using blackberry and raspberry plants, this study tests if the structural integrity of the rootstock can successfully support a scion from a …

Anatomy And Function Of Autonomic Innervation Of The Liver, Kennan Negrete

The Pegasus Review: UCF Undergraduate Research Journal

The liver is one of the most important regulatory organs, and its extensive influence upon homeostatic balance is well-documented. However, the role of autonomic innervation in the control and regulation of hepatic function is poorly understood relative to the other organs of the digestive system. Furthermore, the neuroanatomical layout of the liver remains an incomplete puzzle with various missing pieces. The scarcity of information concerning such a critical organ presents an interesting conundrum for the scientific and biomedical communities alike, especially given the prevalence of liver degeneracy and disease in the modern clinical setting. A more complete understanding of the …

Oyster Reef Restoration: Impacts On Infaunal Communities In A Shallow Water Estuary, Katherine Harris

The Pegasus Review: UCF Undergraduate Research Journal

Oyster reefs are important estuarine ecosystems that provide habitats to many species, including threatened and endangered wading birds and commercially important fishes and crabs. Infaunal organisms (i.e. aquatic, sediment-dwelling organisms) are also supported by oyster reef habitats. Infaunal organisms are critical to oyster-based food webs and are consumed by many important estuarine species. Due to their critical role in coastal food webs, infauna are hypothesized to be strong indicators of habitat productivity. With the dramatic global loss of intertidal oyster reefs, organisms that depend on oyster reef infauna are likely negatively impacted. Fortunately, oyster reef restoration is currently underway in …

Studying The Effects Of Predatory Presence And Enrichment On Cryptoprocta Ferox Behavior, Julie Sharpe

The Pegasus Review: UCF Undergraduate Research Journal

The Central Florida Zoo and Botanical Gardens houses two fossa (Cryptoprocta ferox), a male and a female. C. ferox is an endangered species of Malagasy mongoose from the island of Madagascar. In October of 2018, an amur leopard (Panthera pardus orientalis) was moved across from the male and female C. ferox. This study was used to identify if the presence of P. p. orientalis would affect the stereotypic pacing behavior of the female C. ferox. Staff were also curious about the impact of daily-renewed enrichment on the frequency of pacing in the female. Our …

Exploring The Utility Of Small Unmanned Aerial System (Suas) Products In Remote Visual Stream Ecological Assessment, Alexandra D. Evans, Kevin H. Gardner, Scott Greenwood, Bruce Pruitt

New Hampshire EPSCoR

Many restoration projects’ success is not evaluated (Roni & Beechie 2013; Nilsson et al. 2016), despite available conventional ecological assessment methods. There is a need for more flexible, affordable, and efficient methods for evaluation, particularly those that take advantage of new remote sensing and geospatial technologies (Hubbart et al. 2017). This study explores the use of illustrative small unmanned aerial system (sUAS) products, made using a simple structure-from-motion photogrammetry workflow, coupled with a visual assessment protocol as a remote evaluation and ecological condition archive approach. Three streams were assessed in the field (“surface assessments”) using the Stream Visual Assessment Protocol …

Exploring The Genomic Architectures Of Health, Physical Traits And Antisocial Behavioral Outcomes: A Brief Report, Jorim J. Tielbeek, Brian B. Boutwell

Faculty and Student Publications

© Copyright © 2020 Tielbeek and Boutwell. A widely replicated finding across the behavioral sciences is that antisocial behaviors correlate with an array of health problems. Less clear, however, is the precise nature of this association. There is reason to suspect that a direct causal link exists between incarceration—a consequence of some antisocial behaviors—and certain negative health outcomes, for instance. However, it might be the case that broader phenotypes like antisocial behavior may correlate with certain health and physiological traits at a genomic level. We explore this possibility from a theoretical vantage point, while also presenting some preliminary data from …

Ai Patents: A Data Driven Approach, Brian S. Haney

Chicago-Kent Journal of Intellectual Property

While artificial intelligence (AI) research brings challenges, the resulting systems are no accident. In fact, academics, researchers, and industry professionals have been developing AI systems since the early 1900s. AI is a field uniquely positioned at the intersection of several scientific disciplines including computer science, applied mathematics, and neuroscience. The AI design process is meticulous, deliberate, and time-consuming – involving intensive mathematical theory, data processing, and computer programming. All the while, AI’s economic value is accelerating. As such, protecting the intellectual property (IP) springing from this work is a keystone for technology firms acting in competitive markets.

Gender Differences In Children's Non-Leisure Activities: A Decomposition Analysis, Dayang Haszelinna Abang Ali

Economics and Finance in Indonesia

The prevalence of son preference indicates that girls will have less leisure time compared to boys. This study aims to examine gender differences in weekly hours in schooling, housework, and working among children in Indonesia using Tobit Model and decomposition model of Bauer & Sinning (2005), to test whether son preference explains the differences. The dataset was drawn from the fourth wave of Indonesia Family Life Survey (IFLS) in 2007. The results show significant gender differences in housework and working for children aged 5-14 years and insignificant gender gap in schooling for both age groups. These results confirm the existence …

Ecology Center Publications

Changes in global and regional precipitation regimes are among the most pervasive components of climate change. Intensification of rainfall cycles, ranging from frequent downpours to severe droughts, could cause widespread, but largely unknown, alterations to trophic structure and ecosystem function. We conducted multi-site coordinated experiments to show how variation in the quantity and evenness of rainfall modulates trophic structure in 210 natural freshwater microcosms (tank bromeliads) across Central and South America (18°N to 29°S). The biomass of smaller organisms (detritivores) was higher under more stable hydrological conditions. Conversely, the biomass of predators was highest when rainfall was uneven, resulting in …

Janus: A Python Package For Agent-Based Modeling Of Land Use And Land Cover Change, K. E. Kaiser, A. N. Flores, C. R. Vernon

Geosciences Faculty Publications and Presentations

Janus is an open source Python package for agent-based modeling (ABM) of land use and land cover change (LULCC). Many ABMs of LULCC have been created across platforms, some of which are not ideal for large scale, high resolution scenarios. This model provides a simple object-oriented framework for creating ABMs specific to LULCC. The organizational philosophy of the modeling framework is to create software objects (agents) that are associated with specific and contextual attributes which are isolated from where those agents exist in the spatial setting of the model, and still provide clear linkages between the agent, their environment, and …

Studies Of Quaternary Depositional Systems Of The Coastal Plain And Inner Continental Shelf Along The Georgia Bight: South Carolina And Georgia, U.S.A., Joshua H. Long

Electronic Theses and Dissertations

The Quaternary stratigraphy of the continental shelf offshore of South Carolina consists of stratigraphic units deposited in coastal plain, shallow marine, and shelfal environments bound by composite erosional surfaces that developed in response to numerous glacioeustatic cycles and overprinted by regional uplift. These units are commonly distributed laterally rather than stacked vertically, a function of the long-term, low shelf gradient and the resulting lack of accommodation. This study integrates high-resolution geological and geophysical data sets acquired offshore and onshore with existing data onshore into a comprehensive conceptual model describing the Quaternary geologic evolution of the coastal plain and continental shelf …

Removal Of Iron And Manganese From Groundwater: A Study Of Using Potassium Permanganate And Sedimentation., Mahmoud Elsheikh, Hany Guirguis, Abd El-Rahman Amer

Mansoura Engineering Journal

This paper studies the efficiency of iron (Fe+2) and manganese (Mn+2) removal from groundwater using oxidation by potassium permanganate followed by filtration and using conventional treatment consisting of flocculation, sedimentation and filtration. Experiments were done for different combinations of Fe+2 and Mn+2 concentrations. The obtained results show that Potassium Permanganate (PP) gives good results. By using PP dose equals to half of the theoretically required one, it can remove up to 100% and 90% of iron and manganese respectively over different tested concentrations at pH=7.0. Increasing rate of filtration decreases the Mn+2 removal efficiency obviously. Sedimentation is required when combined …

Convergent Evolution Of Conserved Mitochondrial Pathways Underlies Repeated Adaptation To Extreme Environments, Ryan Greenway, Nick Barts, Chathurika Henpita, Anthony P Brown, Lenin Arias Rodriguez, Carlos M Rodríguez Peña, Sabine Arndt, Gigi Y Lau, Michael P Murphy, Lei Wu, Dingbo Lin, Michael Tobler, Joanna L Kelley, Jennifer H. Shaw

PCOM Scholarly Works

Extreme environments test the limits of life; yet, some organisms thrive in harsh conditions. Extremophile lineages inspire questions about how organisms can tolerate physiochemical stressors and whether the repeated colonization of extreme environments is facilitated by predictable and repeatable evolutionary innovations. We identified the mechanistic basis underlying convergent evolution of tolerance to hydrogen sulfide (H₂S)-a toxicant that impairs mitochondrial function-across evolutionarily independent lineages of a fish (Poecilia mexicana, Poeciliidae) from H₂S-rich springs. Using comparative biochemical and physiological analyses, we found that mitochondrial function is maintained in the presence of H₂S in sulfide …
