Growth, Lipid Production And Biodiesel Potential Of Chromulina Freiburgensis Dofl., An Acidophilic Chrysophyte Isolated From Berkeley Pit Lake, June E. Mohler Mitman Mar 2109

Growth, Lipid Production And Biodiesel Potential Of Chromulina Freiburgensis Dofl., An Acidophilic Chrysophyte Isolated From Berkeley Pit Lake, June E. Mohler Mitman

Graduate Theses & Non-Theses

Microalgae remain a promising, but underdeveloped source of lipids for sustainable biodiesel. Some of the obstacles to cost-effective commercial-scale production have been culture contamination and expensive harvest methods. A chrysophyte isolated from Berkeley Pit Lake and identified as Chromulina freiburgensis, was found to grow rapidly in a pH 2.5 liquid medium and to amass numerous intracellular lipid bodies. This research addresses the scarcity of published knowledge on the topic of chrysophyte species as potential lipid sources for biodiesel. It investigates how growth phase, culture conditions, and harvest timing influence the quantity and composition of lipids produced by this alga ...


Use Of Nest Web Cameras And Citizen Science To Quantify Osprey Prey Delivery Rate And Nest Success, Michael H. Academia, Harmony J. Dalgleish Jun 2022

Use Of Nest Web Cameras And Citizen Science To Quantify Osprey Prey Delivery Rate And Nest Success, Michael H. Academia, Harmony J. Dalgleish

Arts & Sciences Articles

Ospreys (Pandion haliaetus) are obligate piscivores and their nesting success depends on sufficient amounts of fish delivered to the nests during the breeding season. Nests are considered successful when pairs raise a minimum of one young to fledging or near-fledging age. Through web cameras and online broadcasts of Osprey nests, citizen scientists quantified daily number of fish deliveries, nest survival, and nest success. We received and analyzed curated data (one to seven seasons, 2014–2020) from citizen scientist groups representing 19 Osprey web cameras from four countries in North America and Europe. We compared the average and the coefficient of ...


Robert Rosen And Relational System Theory: An Overview, James Lennox Jun 2022

Robert Rosen And Relational System Theory: An Overview, James Lennox

Dissertations, Theses, and Capstone Projects

Relational system theory is the science of organization and function. It is the study of how systems are organized which is based on their functions and the relations between their functions. The science was originally developed by Nicolas Rashevsky, and further developed by Rashevsky’s student Robert Rosen, and continues to be developed by Rosen’s student A. H. Louie amongst others. Due to its revolutionary character, it is often misunderstood, and to some, controversial. We will mainly be focusing on Rosen’s contributions to this science. The formal and conceptual setting for Rosen’s relational system theory is category ...

Evaluation Of Postmortem Protein Expression In Determining Cause Of Death, Zoe Robinson Jun 2022

Evaluation Of Postmortem Protein Expression In Determining Cause Of Death, Zoe Robinson

University Honors Theses

Cause of death differentiation during a medicolegal autopsy can be complicated by several factors, including sample conditions which can create uncertainty. Postmortem protein analysis has potential to be used as an additional evidentiary tool in determining cause of death. Proteomic biomarkers offer a method to directly measure physiological conditions at time of death that are stable in a postmortem state. Specific protein expression levels have been studied for their postmortem application in significantly differentiating many different causes of death. Work done in regard to asphyxial, toxicological, and traumatic deaths will be specifically discussed here. Proteins will be reviewed for potential ...

Seasonal Migration Distance Varies With Natal Dispersal And Predicts Parasitic Infection In Song Sparrows, Tosha R. Kelly, Heather L. Macgillivray, Yanina Sarquis-Adamson, Matthew J. Watson, Keith A. Hobson, Elizabeth A. Macdougall-Shackleton

Biology Publications

Seasonal migration and natal dispersal represent the major large-scale movements in the lives of animals. Individuals that are relatively prone to movement and exploration might thus be more likely to disperse and also to migrate farther. Such movement might be either negatively associated with parasitic infection (if infection prevents hosts from successful long-distance migration) or positively associated (e.g. if longer-distance migrants encounter more abundant or more diverse parasites). We examined whether natal dispersal tendency predicts seasonal migration distance in song sparrows (Melospiza melodia) and whether migration distance predicts infection with bloodborne parasites upon arrival at the breeding grounds. Migration ...

Environmental Toxins Disproportionately Affect Low Income And Minority Communities Along The Providence River, Jalynn Booker

Biology Student Scholarship

The effects of environmental toxins emitted from the various industrial businesses along the Providence River and Allen’s Ave have been reported by residents to cause an incline in respiratory diseases and other illnesses in children and adults in nearby neighborhoods. Operations along Allen’s Ave consist of heavy toxin emitting practices such as hot asphalt mixing, fuels emissions, toxic runoff, gas leaks and piles of scrap metal. Many local news articles and blog posts have reported on the fact that this industrial waterfront has adversely impacted neighboring communities. However, there is little research explicitly comparing the socioeconomic differences between ...


Climate Effects On Butterfly Species Richness, Isabelle Heron May 2022

Climate Effects On Butterfly Species Richness, Isabelle Heron

Biology Student Scholarship

The effects of climate change on the surrounding biodiversity lead scientists to argue an “insect apocalypse” is approaching. Butterflies, as poikilothermic animals, meaning their activity is closely controlled by weather, represent a useful indicator to studying climate change. Scientists can detect changes in butterfly abundance which result in changes in distribution and abundance over a short period of time. BIO 340 final project

Asset Values Of Trees Vary Among Age And Condition, Aidan Castricone

Biology Student Scholarship

Trees are utilized everywhere for visual, physical or functional means with an example being on Providence College campus. We have 1,403 trees part of an inventory and management plan. As part of this plan that was updated this past December 2021 each tree has an asset value calculated with consideration of the size, species, condition, and location. What was not clear in the management plan was whether one factor held more weight in the calculated value compared to another factor. This research focuses on the influence that the age and condition of the tree have on the tree asset ...


Lyme Disease Cases Dependent On Annual Snowfall, Andrew Jordan May 2022

Lyme Disease Cases Dependent On Annual Snowfall, Andrew Jordan

Biology Student Scholarship

Ticks are parasitic arachnids that inhabit every region of the United States. Ticks can spread diseases through feeding on the blood of mammals and birds. Lyme disease is a bacterial infection you can get from the bite of a Blacklegged tick (deer tick), which can lead to long term health effects and can ultimately lead to fatality. Depending on location, up to 50% of ticks in the given area can carry Lyme disease. Lyme disease is a problem and climate change could make it even worse. Whether or not a tick dies in the winter depends on how deep they ...


The Impacts Of Ph On Biodiversity In Marine Environments, Matthew Rock May 2022

The Impacts Of Ph On Biodiversity In Marine Environments, Matthew Rock

Biology Student Scholarship

Climate change continues to impact each and every environment on Earth due to rising levels of greenhouse gasses. CO2 is the most pervasive of these gasses, and when mixed with seawater it creates carbonic acid increasing the pH of water. Ocean acidification has led to large-scale die-offs of more sensitive marine species like coral; therefore, this project serves to evaluate the interaction between pH and the biodiversity of coastal marine environments.

Bird Nesting Trends In Massachusetts, Dieter Rodriguez May 2022

Bird Nesting Trends In Massachusetts, Dieter Rodriguez

Biology Student Scholarship

Bird nesting data has long been documented for various species across the United States. While trends between temperature changes or precipitation on bird nesting have been studied for particular species, studies done on the effects of temperature due to climate change on bird nesting on the broader state level are lacking. Using bird nesting data and average annual temperature data for Massachusetts collected over a ten year period, I assessed the effects of temperature changes over time on bird nesting attempts and total eggs laid for all documented species within the state.

The Effect Of Temperature On Algal Blooms In New York State, Kylie Taylor May 2022

The Effect Of Temperature On Algal Blooms In New York State, Kylie Taylor

Biology Student Scholarship

Water shapes all flora and fauna. Urbanization, industrialization, and other human activities have negatively affected this important source. For example, algal blooms arise due to a combination of sunlight, warm temperatures, and excessive nutrient runoff. The nutrients are a result of fertilizer runoff which enters aquatic systems and cause algal blooms. Increased air temperatures cause increased water temperatures which creates ideal conditions for cyanobacteria growth which are responsible for blooms. Algal blooms affect the entire ecosystem by decreasing sunlight availability in the water. Decreased sunlight contributes to low oxygen dead-zones which negatively affect drinking water reservoirs. I examined the relationship ...

Cross-Modal Perception Of Identity By Sound And Taste In Bottlenose Dolphins, Jason N. Bruck, Sam F. Walmsley, Vincent M. Janik

Faculty Publications

While studies have demonstrated concept formation in animals, only humans are known to label concepts to use them in mental simulations or predictions. To investigate whether other animals use labels comparably, we studied cross-modal, individual recognition in bottlenose dolphins (Tursiops truncatus) that use signature whistles as labels for conspecifics in their own communication. First, we tested whether dolphins could use gustatory stimuli and found that they could distinguish between water and urine samples, as well as between urine from familiar and unfamiliar individuals. Then, we paired playbacks of signature whistles of known animals with urine samples from either the same ...

Simulating Photo-Disintegration Of 137cs Radioactive Waste Using Various Energies Of Gamma Photons, Hassanain H. Alkazzaz, Asia H. Al-Mashhadani, Kamal H. Lateef

Karbala International Journal of Modern Science

In this study, the possibility of using gamma-ray in photo-disintegration method was examined so that it can be used in the remediation of 137Cs radionuclides waste materials by nuclear transmutation to convert long-lived nuclides to other isotopes nuclides, which are shorter half-life (or stable), by different photo-nuclear reaction channels (γ,n), (γ,2n), (γ,p), (γ, a), (γ,d). A simulation code has been written using MATLAB for conducting calculations of reduction and residual. The results showed that gamma-ray fluxes below 1017 [cm-2 s-1] are not adequate to perform effective incinera-tion of 137Cs, and as for gamma flux of 1018 ...

Karbala International Journal of Modern Science

The COVID-19 outbreak has infected millions of people worldwide, but no vaccine has been discovered to combat it efficiently. This research aims to design a multi-epitope vaccine using highly efficient B- and T-cell epitopes from the SARS-CoV-2 Surabaya isolate through a viroinformatic approach. First, the putative epitopes were linked together to develop tertiary structures and then docked with toll-like receptor 4 (TLR-4) that demonstrated a robust interaction with a low eigenvalue of 4.816138 e-06. Furthermore, the structure's high immunogenic response was observed and successfully cloned into the expression vector pET28a (+). This implies that the designed vaccine can prove ...


Does Manuka Honey Induce Antibiotic Resistant Bacterial Persisters And Viable But Non-Culturable Subpopulations?, Bryn Tennyson May 2022

Does Manuka Honey Induce Antibiotic Resistant Bacterial Persisters And Viable But Non-Culturable Subpopulations?, Bryn Tennyson

2022 Symposium

Long-term antibiotic use has allowed microbes to develop resistance and cause chronic infectious diseases that were previously treatable. Resistance is phenomenon in which bacteria survive treatment with a concentration of antibiotics that was once lethal. Bacteria resist antibiotic treatment by genetic change or initiating states of dormancy called persisters or Viable but Non-Culturable (VBNCs) cells. These subpopulations of antibiotic resistant persisters and VBNCs increase with exposure to stresses, including antibiotic treatment, and are a major cause of reoccurring infections that result in significant morbidity and mortality. Manuka honey (MH), a well-known alternative broad-spectrum antimicrobial, is a promising treatment for cutaneous ...


Gene Expression Analysis Revealed The Activation Of Immune Responses During The Postnatal Development Of The Cerebellum In A Mouse Model Of Niemann-Pick Type C, Sierra Elizabeth Melli May 2022

Gene Expression Analysis Revealed The Activation Of Immune Responses During The Postnatal Development Of The Cerebellum In A Mouse Model Of Niemann-Pick Type C, Sierra Elizabeth Melli

Theses and Dissertations

Niemann-Pick Type C (NPC) is a recessive neurodegenerative lysosomal storage disorder that is caused by autosomal recessive mutations. The mutations result in the inactivation of NPC1 and NPC2 proteins. Inactivation of the NPC1 protein results in the accumulation of cholesterol within the endosomal and lysosomal compartments of cells including Cerebellar Purkinje cells. This accumulation of cholesterol leads to symptoms of dementia, neurodegeneration and potential of early childhood death in cases of early onset. In this study, we analyze the gene expression levels using the RNAseq technique in order to determine whether there is a significant difference between the expression of ...

Marine traffic is increasing globally yet collisions with endangered megafauna such as whales, sea turtles, and planktivorous sharks go largely undetected or unreported. Collisions leading to mortality can have population-level consequences for endangered species. Hence, identifying simultaneous space use of megafauna and shipping throughout ranges may reveal as-yet-unknown spatial targets requiring conservation. However, global studies tracking megafauna and shipping occurrences are lacking. Here we combine satellite-tracked movements of the whale shark, Rhincodon typus, and vessel activity to show that 92% of sharks’ horizontal space use and nearly 50% of vertical space use overlap with persistent large vessel (>300 gross tons ...

Honors Projects

Quercus palustris and Quercus alba acorns are a primary component in many wild animal diets, particularly during preparation for winter. As such, they provide a natural, easily gathered food staple for wildlife recovering in rehabilitation facilities. We examined whether collection and temperature-controlled storage methods differentially affect the nutritional deterioration of crude fat in acorns to assess both caching by wildlife and to provide recommendations to rehabilitators. We collected acorns from Q. palustris in 2020 (N=8) and Q. alba in 2017 (N=11) in Bridgewater, VA, USA. Acorns were dried for 7 days using a fan or for 30 minutes ...


Isolation Of Arabidopsis Thaliana Plants Homozygous For An Insertional Inactivation Mutation Within Atprp4., Sydney Raitz, Timothy D. Trott May 2022

Isolation Of Arabidopsis Thaliana Plants Homozygous For An Insertional Inactivation Mutation Within Atprp4., Sydney Raitz, Timothy D. Trott

Faculty Works

The AtPRP4 gene in Arabidopsis thaliana has been shown to function in several specific parts of the plant’s cell wall. It is shown to be expressed in the seeds, radicles, roots, leaves, inflorescences, and embryos of Arabidopsis thaliana. These patterns have suggested unique functions for ATPRP4 in determining cell-type-specific wall structure during the development of a plant as well as contributing to defense reactions against physical damage to the plant and pathogen infection within the plant. In this study, a simple DNA prep was performed on the true leaves of Arabidopsis thaliana. Subsequent PCR reactions were performed using AtPRP4F ...

Integrating Radio Telemetry And Accelerometry To Evaluate The Scale-Dependent Effects Of Roadways On The Movement Patterns Of Timber Rattlesnakes (Crotalus Horridus), Anna F. Tipton

Biology Theses

Roadways are among the most widespread and disruptive anthropogenic land use features that influence the behavior and movement of wildlife. Negative impacts such as vehicle-induced mortality, habitat destruction and fragmentation, and the creation of barriers to movement have been well documented across taxa, but the fine-scale behavioral impact of roadways on smaller, cryptic species has yet to be directly examined. Using a novel integration of radio telemetry and tri-axial accelerometry, we evaluated the movement response of Timber Rattlesnakes (Crotalus horridus) to roadways in central Georgia. We quantified individual C. horridus movement and space use with both radio telemetry and accelerometry ...

Karbala International Journal of Modern Science

Ethereum smart contracts have recently received new commercial applications and a lot of attention from the scientific community. Ethereum eliminates the requirement for a trusted third party by allowing untrusted parties to expose contract details in computer code. Nonetheless, as online commerce grows, plenty of fraudulent activities, such as money laundering, bribery, and phishing, emerge as major threats to trade security. For correctly recognizing fraudulent transactions, this paper developed a Light Gradient Boosting Machine (LGBM) technique-based model. The modified LGBM model optimized the parameters of Light GBM using the Euclidean distant structured estimation approach. This paper also examines the performance ...

A Bi-Level Data Lowering Method To Minimize Transferring Big Data In The Sensors Of Iot Applications, Ali Kadhum M. Al-Qurabat, Ali Kadhum Idrees, Abdallah Makhoul, Chady Abou Jaoude

Karbala International Journal of Modern Science

In the IoT era, the number of devices connected to it continues to grow significantly. This can lead to an increase in the amount of reported data by these IoT devices. The reported data by the Sensor Nodes (SNs) to the Gateway (GW) drives these IoT sensors to consume their energy and storage. These problems can be solved by reducing the amount of data in the source nodes in order to reduce both the amount of energy consumed and the amount of storage required. Energy consumption represents one aspect of the Quality of Service (QoS) in the sensor nodes of ...
