Optimal Recipe Screening And Applications Of Iron-Filings Based Green Environmental Media (Ifgem) For Stormwater Treatment, Andrea Valencia

Electronic Theses and Dissertations

The applications of green sorption media for stormwater treatment and nutrient removal benefit surface and ground water bodies by reducing non-point source pollution from stormwater runoff. To enhance nitrogen and phosphorus removal, a sequential study was performed to develop an improved green sorption media in this study by including the iron filings into the previous biosorption activated media (BAM). The iron-filings-based green environmental media (IFGEM) are thus composed of sand, tire crumb, clay and ground iron filings in which clay and iron particles are supposed to have salient interactions that cannot be present in BAM. However, the optimal ratio between …

The Relationship Of Spirituality, Religiosity And Attitudes Toward Lesbians And Gay Men Among Students At A Faith-Based Institution, Megan C. Cormier Castaneda

Pennsylvania’S Need For Permanency: An Argument In Support Of Workable Standards For Representing Children In Involuntary Termination Of Parental Rights Proceedings, Anne M. Bingaman

Dickinson Law Review (2017-Present)

In cases of child abuse and neglect, Pennsylvania’s dependency laws both empower courts to act to protect the child and offer opportunities to bolster the parent-child relationship. However, when courts determine that maintenance of the parent-child relationship is not in the child’s best interest, termination of parental rights proceedings play an essential role in freeing the child for adoption.

Pennsylvania’s General Assembly has recognized that termination proceedings are both a necessary mechanism for permanency and a significant intrusion in the life of a child. As a result, the General Assembly enacted 23 PA. CONST. STAT. § 2313(a), a provision in …

Development Of Multicomponent Eam Potential For Ni-Based Superalloy, Muztoba Rabbani

Graduate Theses/Dissertations

We initiated the development of multi-component EAM potentials for Aluminides and Carbides, key phases in Ni-based Superalloys. The goal is to utilize the MD simulation to understand the deformation dynamics that contribute to the formation of voids and creep initiation. For this purpose, we constructed the raw data from ab-initio (molecular dynamics) MD simulations fed into the potential development code and used Nickel as the base metal with the addition of a number of various elements including Aluminum, Chromium, Tungsten.

Evaluating The Role Of A Cav2.2 Splice Variant In Behavioral Responses To Stress, Novelty, And Other Monoamine-Linked Functions, Ashton Brennecke

Master's Theses and Capstones

CaV2.2 (N-type) channel is a presynaptic channel that enables calcium influx into axon terminals, thereby playing a vital role in coupling action potentials to neurotransmitter release in the central and peripheral nervous systems. In vitro studies of CaV2.2 show that the channel directly modulates levels of the monoamines including dopamine, serotonin, and norepinephrine. Further, CaV2.2-null mice exhibit heightened aggression and hyperlocomotion linked to aberrant dopamine and serotonin function. All these studies suggest that CaV2.2 plays a pivotal role in monoaminergic function. CaV2.2 contains an alternatively spliced exon, e18a, which is either included (+18a-CaV2.2) or removed (Δ18a-Ca¬V2.2) from the channel and …

The Effect Of Meloxicam On The Ability Of Neonatal Dairy Calves To Absorb Igg Provided By Colostrum Replacer, Meaghan O.C. Clark

Master's Theses and Capstones

The objective of this study was to determine the effect of meloxicam, administered either in pill form immediately prior to colostrum replacer (CR), or powder form, mixed in solution with CR, on the immunoglobulin G (IgG) uptake, growth, and health of pre-weaned calves. A pilot study considering the potential benefits of meloxicam in pre-weaned heifers indicated administration of the drug following difficult parturition improved body weight (BW) and overall health, but was not associated with passive transfer of immunity (Murray et al., 2015). However, calves from this study were sampled from 10 commercial farms, and therefore, treatment administration was inconsistent, …

Spinning Charlotte's Web: Resident Perceptions And Neutralizations Of A Slaughterhouse Town, Ashley L. Flaherty

All Graduate Theses, Dissertations, and Other Capstone Projects

Meat production, consumption, and slaughterhouses significantly affect the environment, public health, and non-human animals. Those who live in communities that house slaughterhouses must negotiate what it means to live and work in this community, and be financially supported by the industry. Understanding how people negotiate the roles that the industry plays in their community through semi-structured interviews was the primary purpose of this study. To reconcile the issues the town faces, the respondents in this study used excuses and justifications, specifically techniques of neutralization, to account for both the company's actions and the social issues the city itself faces.

The Effects Of Heat-Killed Echinostomatid Parasites On Mice Treated With Dextran Sodium Sulfate (Dss), Natalie Gooder

All Graduate Theses, Dissertations, and Other Capstone Projects

Objective: Autoimmune diseases are chronic, incurable, and affect approximately 50 million Americans. This is a strong need for better ways to treat autoimmune diseases. Parasites and parasite proteins have been observed to protect mice from symptoms of induced colitis in mice treated with dextran sodium sulfate (DSS), a model for inflammatory bowel disease (IBD). I hypothesize that non-living echinostomatid parasites, given during DSS treatment, can decrease intestinal inflammation and weight loss, providing a possible novel treatment for IBD.

Methods: A range of DSS concentrations (0.5%-3%) were delivered to female C57BL/6 mice in their drinking water in order to determine the …

Demography, Risk, And Power: An Examination Of The Deceased Patient Population At The Hastings State Hospital, 1900-1978, Dawn T. Whitney

All Graduate Theses, Dissertations, and Other Capstone Projects

The purpose of this research is to investigate the Hastings State Hospital (HSH) and its cemetery (HSHC) within a multidisciplinary framework, invoking discourse analysis, demography, and critical race theory to examine how power and risk factors impact the treatment and disposal of the body at death. It incorporates perspectives from both anthropology and sociology to interpret the data, relying heavily on the ideas of Michel Foucault. Integrating these diverse analytical tools is important to this research because social and structural forces all intersect in the creation of identity, power, and inequality.

The Effect Of Dorsal Rhizotomy On Renal Sodium Excretion Following Dorsal Spinal Stimulation, Tanko Tijani Ahmed

All Graduate Theses, Dissertations, and Other Capstone Projects

Hypertension is one of the most common risk factors in the development of heart disease, stroke and end stage renal failure. Sympathetic overactivity is believed to be one of the main mechanism behind resistant hypertension. Renal denervation has been used to treat resistant hypertension, although this procedure is an invasive one. Spinal cord stimulation (SCS) is a known modality to treat ischemic pain, angina pectoris, and peripheral vascular diseases. In previous studies in this laboratory, unilateral spinal cord stimulation in spontaneously hypertensive rat (SHR) at 67% of the motor threshold increased urinary sodium and water excretion significantly, without affecting mean …

Metabolic And Morphological Evaluation Of Two Brewer’S Yeast Strains Throughout Serial Re-Pitching In Beer Fermentation, Anh Pham

All Graduate Theses, Dissertations, and Other Capstone Projects

Beer fermentation is the process of growing yeast anaerobically in a malt-based medium, ultimately resulting in alcohol and carbon dioxide production. In order to reduce the cost and waiting time, serial repitching has been practiced among microbrewers. The technique emphasizes transferring yeast from one batch of beer to the subsequent brewing cycles. It has been shown that aged yeast cultures have higher fermentation efficiency and shorter lag period, thereby resulting in shorter fermentation times, faster pH drop, and lower concentrations of unwanted products. Despite the advantages of serial repitching, one can only practice repitching for approximately 5-6 times with a …

Castration-Resistant Prostate Cancer: Androgen Receptor Inactivation Induces Telomere Dna Damage, And Damage Response Inhibition Leads To Cell Death, Vidyavathi Reddy, Asm Iskander, Clara Hwang, George Divine, Mani Menon, Evelyn R. Barrack, Prem-Veer Reddy, Sahn-Ho Kim

Urology Articles

Telomere stability is important for cell viability, as cells with telomere DNA damage that is not repaired do not survive. We reported previously that androgen receptor (AR) antagonist induces telomere DNA damage in androgen-sensitive LNCaP prostate cancer cells; this triggers a DNA damage response (DDR) at telomeres that includes activation of ATM, and blocking ATM activation prevents telomere DNA repair and leads to cell death. Remarkably, AR antagonist induces telomere DNA damage and triggers ATM activation at telomeres also in 22Rv1 castration-resistant prostate cancer (CRPC) cells that are not growth inhibited by AR antagonist. Treatment with AR antagonist enzalutamide (ENZ) …

The Lived Experiences Of Emotionally Forgiving Abusive Parents, Chelsea Bryant

Walden Dissertations and Doctoral Studies

The subject of forgiveness has been heavily explored during the past few decades; however, limited research has been conducted on the phenomenology of emotional forgiveness, the internal process of replacing negative feelings with positive feelings. This study explored the emotional forgiveness experiences of 7 adult men who were previous victims of abuse by their parents. Using Moustakas's phenomenological research approach, the participants were interviewed about their experiences of emotional forgiving their abusive parents. The recall, empathize, altruism, commitment, and holding on, REACH forgiveness model and family systems theory were the conceptual frameworks to explore the central research question, which addressed …

Ethnic Minority Young Adult Perspectives On Health Literacy Readiness For Adulthood, Selwyn A. B. Carrington

Walden Dissertations and Doctoral Studies

Health literacy is a social determinant of health and health disparity and low health literacy contributes to poor health outcomes in ethnic minority young adults (EMYAs). There is a gap in the literature regarding the health literacy readiness (HLR) of EMYAs transitioning to adulthood. The overarching research question concerned the perspectives of EMYAs on HLR for the transition to adulthood. A phenomenological study design was used with a theoretical framework that integrated concepts from the socioecological and health belief models. Twelve purposefully selected EMYAs ages 18-22 from a southern U.S. county participated in the study. Data were collected by telephone …

African American Women's Perceptions Of Self-Value In The Transition To Natural Hair, Tekeilla Darden

Walden Dissertations and Doctoral Studies

Scholars have reported on the upsurge of African American women wearing their kinky, or natural, hair and the issues surrounding their choices. The wearing of natural African American hair has not been fully accepted in mainstream society. The purpose of this phenomenological study was to explore how African American women understand self-value in the process of wearing their natural hair. The ethnic and racial identity model, critical race theory, and the strong Black woman collection were the conceptual frameworks used to connect identity, race and racism, and a collective vulnerability to the African American woman's hair journey. The study included …
