Characterising Cytotoxicity And Genotoxicity Of Chemotherapeutic Agents (Etoposide And Vincristine) On Tk6, A Human Lymphoblastoid Cell Line, Leanne Edermaniger
The Plymouth Student Scientist
The ability of the chemotherapeutic agents namely etoposide and vincristine to cause cytotoxic and genotoxic damage to the human lymphoblastoid cell line, TK6, was at the centre of this study. Four different cytotoxic assays were tested for their ability to assess the cytotoxicity of the agents as well as two genotoxic assays to examine their ability to induce DNA damage. The TK6 cell line was exposed to increasing doses of the chemotherapeutic agents and cytoxicity assessed by in vitro trypan blue, neutral red uptake, LDH leakage and the glucose oxidase assays. The trypan blue assay was deemed to be the …
Building An Aging Advocacy Network: Findings From The New Hampshire Senior Leadership Series, Susan Fox, Laura K. Davie, Alison C. Rataj
Building An Aging Advocacy Network: Findings From The New Hampshire Senior Leadership Series, Susan Fox, Laura K. Davie, Alison C. Rataj
Institute on Disability
Public policy related to senior issues has not kept pace with the changes called for by an aging population. Advocacy is an important part of the policy landscape as it promotes a united effort to create change and encourage legislative action. Effective advocacy helps inform and educate policy makers, allows individuals to have their voices heard, builds stronger communities, and allows people to live more fulfilling lives. However, policy makers are inundated with causes to support, and it is easy for certain populations or causes to be lost in this process. This has been especially true for advocacy efforts around …

Bimetallic-Waveguide Coupled Sensors For Tunable Plasmonic Devices, Kunal K. Tiwari
Bimetallic-Waveguide Coupled Sensors For Tunable Plasmonic Devices, Kunal K. Tiwari
Physics Dissertations - Archive
Surface plasmon resonance (SPR) has been a widely used optical technique for the real time and label free sensing applications in biomedicine, homeland security, food safety, environmental monitoring, etc. Surface plasmons (SPs) being extremely sensitive to the surrounding media, their characteristics can be modulated by tuning their dielectric environment. The unique property of the nematic liquid crystalline materials that their dielectric constant can be tuned by externally applied electric fields formed the basis for development of tunable plasmonic sensor for monitoring changes at metal/dielectric interfaces. Even though sensors with high sensitivity are available, it remains highly desirable to enhance sensor …
Choosing Progress: Evaluating The "Salesmanship" Of The Vietnam War In 1967, Gregory A. Daddis
Choosing Progress: Evaluating The "Salesmanship" Of The Vietnam War In 1967, Gregory A. Daddis
History Faculty Books and Book Chapters
"As the president and his war managers increasingly saw Vietnam as a 'race between accomplishment and patience,' publicizing progress became an integral part of the war. Yet far from a unique case of bureaucratic dishonesty, the 1967 salesmanship campaign demonstrates the reality, even necessity, of conversation gaps when one is assessing progress in wars where the military struggle abroad matters less than the political one at home."
Facile Sol-Gel Molten Salt Synthesis Of Double Perovskite La 2nimno6 As An Electrocatalyst For Oxygen Evolution Reactions, Padmini Kukkapalli
Facile Sol-Gel Molten Salt Synthesis Of Double Perovskite La 2nimno6 As An Electrocatalyst For Oxygen Evolution Reactions, Padmini Kukkapalli
Theses and Dissertations
Double perovskites have attracted a great attention recently for its high intrinsic activity in oxygen evolution reaction (OER) in electrochemical energy storage and conversion systems in alkaline media. In this study, we are the first to report the new approach of La2NiMnO6 double perovskite which was synthesized via Sol-gel molten-Salt synthesis method. However their stability and specific activity remain challenging that need to be addressed to meet the reqiurement for OER activities. Here in this study we synthesized three different samples with varying concentrations by taking molten salts NaNO 3 and KNO3 in (1:1) ratio such as 30:30, 60:60, 90:90. …
The Relationship Between Ethical Regard And Academic Misconduct Among College Students, Susan Dickey
The Relationship Between Ethical Regard And Academic Misconduct Among College Students, Susan Dickey
Electronic Theses and Dissertations
A correlational quantitative research project was conducted at a large public research institution in the Southeast to investigate the relationship between ethical regard and academic dishonesty among undergraduate college students. An online survey was completed by 273 undergraduates. Participant engagement in cheating behaviors established a Propensity To Cheat (PTC) score, which was then analyzed in conjunction with student characteristics, ethical self-perception, ethical ideology, and perception of cheating behaviors. Data were analyzed using ANOVAs, independent t tests, correlations, and descriptive statistics.
Findings indicate that students aged 22-23 were significantly more likely to cheat than students in other age ranges; Millennials were …
Assessing The Physical Security Of Idfs With Psatool: A Case Study, Sulabh Bista
Assessing The Physical Security Of Idfs With Psatool: A Case Study, Sulabh Bista
Electronic Theses and Dissertations
PSATool is a checklist-based, web-based application for assessing the physical security of Intermediate Distribution Frameworks. IDFs, or wiring closets, are an integral if often neglected component of information security. Earlier work by Timbs (2013) identified 52 IDF-related security requirements based on federal and international standards for physical security. PSATool refines Timbs’ prototype application for IDF assessment, extending it with support for mobile-device-based data entry.
PSATool was used to assess 25 IDFs at a regional university, a college and a manufacturing corporation, with an average of 9 minutes per assessment. Network managers and assessors involved in the assessments characterized PSATool as …
The Human Terrain System: Operationally Relevant Social Science Research In Iraq And Afghanistan, Christopher Sims Dr.
The Human Terrain System: Operationally Relevant Social Science Research In Iraq And Afghanistan, Christopher Sims Dr.
Books, Monographs & Collaborative Studies
The Human Terrain System embedded civilians primarily in brigade combat teams (BCTs) in Iraq and Afghanistan between 2007 and 2014 to act as a collection and dispersal mechanism for sociocultural comprehension. Set against the backdrop of the program’s evolution, the experiences of these social scientists clarifies the U.S. Army’s decision to integrate social scientists at the tactical level in conflict. Based on interviews, program documents, material from Freedom of Information Act requests, and secondary sources, this book finds a series of limiting factors inhibiting social science research at the tactical level, common to both Iraq and Afghanistan. Complexity in integrating …
Sophorolipid Production From Lignocellulosic Biomass Feedstocks, Abdul Samad
Sophorolipid Production From Lignocellulosic Biomass Feedstocks, Abdul Samad
Theses
The present study investigated the feasibility of production of sophorolipids (SLs) using yeast Candida bombicola grown on hydrolysates derived lignocellulosic feedstock either with or without supplementing oil as extra carbon source. Several researchers have reported using pure sugars and various oil sources for producing SLs which makes them expensive for scale-up and commercial production. In order to make the production process truly sustainable and renewable, we used feedstocks such as sweet sorghum bagasse, corn fiber and corn stover. Without oil supplementation, the cell densities at the end of day-8 was recorded as 9.2, 9.8 and 10.8 g/L for hydrolysate derived …
The Never Ending Confession: The Confessional Mode In Two Novels By Mempo Giardinelli, Ryan Russel Hill
The Never Ending Confession: The Confessional Mode In Two Novels By Mempo Giardinelli, Ryan Russel Hill
Theses and Dissertations
In the years following the military dictatorship in Argentina many novels were published that spoke about the violence, terror, and traumas experienced during the Junta's rule. These texts deal with the theme of memory and retell the traumas of the past as a form of mourning. Such novels look back to the past in an effort to redeem it. In this essay I explore the use of the confessional mode in postdictatorial literature as a vehicle for the task of mourning. In two of his novels, Qué solos se quedan los muertos (1985) and Cuestiones interiores (2003), Argentine author Mempo …
Mountain Big Sagebrush (Artemisia Tridentata Ssp Vaseyana) Seed Production, Melissa L. Landeen
Mountain Big Sagebrush (Artemisia Tridentata Ssp Vaseyana) Seed Production, Melissa L. Landeen
Theses and Dissertations
Big sagebrush (Artemisia tridentata Nutt.) is the most widespread and common shrub in the sagebrush biome of western North America. Of the three most common subspecies of big sagebrush (Artemisia tridentata), mountain big sagebrush (ssp. vaseyana; MBS) is the most resilient to disturbance, but still requires favorable climactic conditions and a viable post-fire seedbank for successful unassisted recovery. This study was designed to assess MBS seed production throughout post-fire recovery. We performed 2 pilot studies to develop methods for estimating seed production and plant age. The results of the pilot studies and a space-for-time substitution strategy were used to measure …

Gene Networks Involved In Competitive Root Colonization And Nodulation In The Sinorhizobium Meliloti-Medicago Truncatula Symbiosis, Ryan D. Vanyperen
Gene Networks Involved In Competitive Root Colonization And Nodulation In The Sinorhizobium Meliloti-Medicago Truncatula Symbiosis, Ryan D. Vanyperen
Theses and Dissertations
The rhizobia-legume symbiosis is the most agriculturally significant source of naturally fixed nitrogen, accounting for almost 25% of all biologically available nitrogen. Rhizobia-legume compatibility restrictions impose limits on symbiotic nitrogen fixation. In many cases, the molecular basis for symbiotic compatibility is not fully understood. The signals required for establishing a symbiotic partnership between nitrogen-fixing bacteria (e.g. Sinorhizobium meliloti) and leguminous plants (e.g. Medicago truncatula) have been partially characterized at the molecular level. The first stage of successful root colonization is competitive occupation of the rhizosphere (which is poorly understood). Here, the bacteria introduce themselves as potential symbiotic partners …
A Corpus-Based Analysis Of Russian Word Order Patterns, Stephanie Kay Billings
A Corpus-Based Analysis Of Russian Word Order Patterns, Stephanie Kay Billings
Theses and Dissertations
Some scholars say that Russian syntax has free word order. However, other researchers claim that the basic word order of Russian is Subject, Verb, Object (SVO). Some researchers also assert that the use of different word orders may be influenced by various factors, including positions of discourse topic and focus, and register (spoken, fiction, academic, non-academic). In addition, corpora have been shown to be useful tools in gathering empirical linguistic data, and modern advances in computing have made corpora freely available and their use widespread. The Russian National Corpus is a large corpus of Russian that is widely used and …
Audience Participation In Blue Man Group: Success Through Authentic Character, Adaptable Narrative, And Accessible Space, Haley Lauren Flanders
Audience Participation In Blue Man Group: Success Through Authentic Character, Adaptable Narrative, And Accessible Space, Haley Lauren Flanders
Theses and Dissertations
The relationship between performer and spectator is a constant topic in theatre since audiences are essential to any performance. Some contemporary performances strive to blur the line between the two by allowing audiences to participate during the show. Often, audience participation is despised and therefore avoided by spectators and theatre practitioners. However, Blue Man Group thrives on it due to their authentic character, adaptable narrative, and accessible space. Through my examination of the show as an audience member, I theorize that these three elements control the audience's willingness to participate in the production and in turn make the entire experience …

Functional Characterization Of Aggregatibacter Actinomycetemcomitans Qsebc : A Bacterial Adrengeric Receptor And Global Regulator Of Virulence., Whitney Weigel
Electronic Theses and Dissertations
In order for a pathogen to successfully colonize the host, it must be able to acquire essential nutrients and regulate gene expression to respond to environmental fluctuations. One mechanism bacteria have evolved in order to detect these fluctuations and respond is the two component signal transduction systems (TCS). Aggregatibacter actinomycetemcomitans, a dental commensal associated with localized aggressive periodontitis, contains a TCS designated QseBC that was previously shown to regulate expression of several iron acquisition genes, biofilm formation and virulence, but the activating signal was unknown []. QseBC is a conserved TCS in the Enterobacteriaceae and Pasteurellaceae, but the activating signal …
