Syntheses And Characterization Of Advanced Nanocomposites And Platinum Complexes, Jing Fang Dec 2013

Syntheses And Characterization Of Advanced Nanocomposites And Platinum Complexes, Jing Fang

Theses (Pre-2016)

The present research focuses on the following two areas: (1) to prepare advanced nanocomposites through electropolymerization, and (2) to synthesize novel platinum complexes. (1) Substrate-Enhanced Electrodeposition of Polypyrrole on Carbon Nanotubes. Silver membrane filter (SMF) was utilized as a substrate, where carbon nanotubes (CNTs) were anchored and evenly distributed in its highly porous yet interconnected microstructure through vacuum filtration. Taking advantage of SMF's superb electrical conductivity, the CNTs-loaded SMF could be engaged as a working electrode, where pyrrole was electropolymerized on the surface of CNTs. Scanning electron micrograms demonstrated that polypyrrole (PPy) grew more evenly on the H202/HCl-pretreated single-walled CNTs …

Environmental Beliefs And Concern About Animal Welfare: Exploring The Connections, Catherine A. Faver Dec 2013

Environmental Beliefs And Concern About Animal Welfare: Exploring The Connections, Catherine A. Faver

The Journal of Sociology & Social Welfare

An online survey examined environmental beliefs and concern about animal welfare among 105 social work students in the U.S.- Mexico border region. Environmental beliefs were measured using items from the revised New Ecological Paradigm (NEP) Scale (Dunlap, Van Liere, Mertig, & Jones, 2000). Higher concern about animal welfare was significantly related to three dimensions of the revised NEP Scale: (1) belief in the fragility of nature's balance, (2) belief in the possibility ofan ecological crisis, and (3) rejection of the notion that humans have a right to dominate nature (anti-anthropocentrism). The findings suggest that by making explicit connections between the …

Variations Of Vibrio Populations In Pacific White Shrimp, Litopenaeus Vannamei, Aquaculture Raceways, Tracy Rene Berutti Dec 2013

Variations Of Vibrio Populations In Pacific White Shrimp, Litopenaeus Vannamei, Aquaculture Raceways, Tracy Rene Berutti

Master's Theses

Reducing incidence of vibrioses in intensive aquaculture systems is essential to maintaining yields. This study performed real-time qPCR (quantitative polymerase chain reaction) using primers targeting 16s rDNA sequences for total bacteria, the Vibrio genus, and Vibrio parahaemolyticus in aquaculture tanks over the growing season. Total DNA concentrations in each sample were measured with a NanoDrop 2000 Spectrophotometer (Thermo Scientific, Inc. USA). These data were compared to two levels of bio-floc solids removal in addition to physical and chemical tank parameters such as temperature, ammonia, nitrite, nitrate and phosphate. The total bacteria gene copy abundances were higher (p = 0.0081) …

La Diversidad De Los Análisis De Diversidad La Diversidad De Los Analisis De Diversidad [The Diversity Of Diversity Analyses], Victor D. Carmona-Galindo, Tizziana V. Carmona

Biology Faculty Works

There is a lack of consistency with respect to the use of the terms like species richness, diversity and biodiversity, which extends to the analysis of diversity indices and the merit of using diversity indices in the evaluation (comparison and contrast) of biological communities. The purpose of this article is to provide working definitions for these terms and cite examples from the primary literature that demonstrate the utility of estimating richness, evaluating proportional abundance patterns, as well as comparing indices of diversity and similarity to study patterns of biological organization at different ecological scales. Additionally, we provide a manual in …

What Factors Structure Anthozoan Microbial Communities?, Joanna Warwick-Dugdale Dec 2013

What Factors Structure Anthozoan Microbial Communities?, Joanna Warwick-Dugdale

The Plymouth Student Scientist

The coral holobiont is a complex and diverse composition of organisms including algae, bacteria and viruses. A number of factors suggested as vital in shaping these communities are considered here. The anthozoan host generates great diversity within its microbiota via spatial and metabolic structuring at both macro- and micro-scales; coral communities appear to be somewhat species-specific, yet spatial and temporal variation in coral microbiota suggests the significance of environmental agents. Increasing sea temperatures may cause fatal dissolution of the coral-algal partnership (coral bleaching), and although some adaptation to elevated temperature appears possible, anthropogenic stressors such as reduced pH and sedimentation …

The Medicinal And Pharmacological Screening Of Wheatgrass Juice (Triticum Aestivum L.): An Investigation Into Chlorophyll Content And Antimicrobial Activity, Patrick Wakeham Dec 2013

The Medicinal And Pharmacological Screening Of Wheatgrass Juice (Triticum Aestivum L.): An Investigation Into Chlorophyll Content And Antimicrobial Activity, Patrick Wakeham

The Plymouth Student Scientist

Plant products are of increasing interest in the search for new drugs and medicines in the treatment of disease; and the discovery of new alternatives to existing antibiotics is an important area of this research due to pathogen resistance. One example of a plant product currently under pharmacological investigation is wheatgrass juice; a dietary supplement derived from Triticum aestivum L. There is both anecdotal and scientific evidence to suggest that the medicinal efficacy of this plant may be due to its high chlorophyll concentrations. In this study chlorophyll fresh weight was determined in mg/100g for organic field grown wheatgrass juice …

The Effect Of Copper-Induced Oxidative Stress On Regeneration In Anemonia Viridis (Forskäl, 1775), Katharine Childs Dec 2013

The Effect Of Copper-Induced Oxidative Stress On Regeneration In Anemonia Viridis (Forskäl, 1775), Katharine Childs

The Plymouth Student Scientist

The release of pollutants such as metals into the aquatic environment has raised concerns over the health of coral reefs, as elevated concentrations of metals are known to cause oxidative stress and bleaching. This is an important issue to address as metals are continuously released into the environment and there is evidence that metals such as copper can still be prevalent after historical mining activities, particularly in estuaries around the Plymouth Sound, UK. Anemonia viridis is commonly found around this area and is used in the literature as a model organism for coral species. A.viridis harbours symbiotic zooxanthellae and is …

Heat Stress In Captive Endothermic Animals, Samantha Ward Dec 2013

Heat Stress In Captive Endothermic Animals, Samantha Ward

The Plymouth Student Scientist

Approximately 26 billion captive animals, spanning over 10, 000 species (Mason 2010) are housed in artificial habitats and face a wide range of potential environmental challenges. These include abiotic sources of stress, for instance, artificial lighting, exposure to loud or aversive sound, arousing odours and uncomfortable temperatures or substrates. In addition, confinement-specific stressors such as restricted movement, forced proximity to humans or conspecifics, reduced feeding opportunities and other behavioural restrictions (Morgan & Tromborg 2007). There is enormous variation between species in how they react to captivity, even among close taxonomic relatives (Mason 2010). Captive wild animals are often healthier, live …

Feeding Strategies In Sympatric Red Howler Monkeys (Alouatta Seniculus), Saddleback Tamarins (Saguinus Fuscicollis) And Squirrel Monkeys (Saimiri Boliviensis), In The Pacaya-Samiria National Reserve, Peru, Aimee May Dec 2013

Feeding Strategies In Sympatric Red Howler Monkeys (Alouatta Seniculus), Saddleback Tamarins (Saguinus Fuscicollis) And Squirrel Monkeys (Saimiri Boliviensis), In The Pacaya-Samiria National Reserve, Peru, Aimee May

The Plymouth Student Scientist

This study investigated the feeding strategies of sympatric red howlers (Alouatta seniculus), saddleback tamarins (Saguinus fuscicollis) and squirrel monkeys (Saimiri boliviensis) in the Pacaya-Samiria National Reserve, Peru. The habitat types occupied during all behaviours and purely when feeding differed significantly between the three species (p<0.005). The overall diet consumption was also shown to be significantly different between the three species (p<0.005). These results demonstrated that niche separation between these sympatric primates may be achieved through differences in habitat types used for foraging and food types consumed. Data from this study was compared with data collected at the same site using the same methods in 2011. The diet composition differed significantly within each of the species between 2011 and 2012 (p<0.005). It could be proposed that factors such as changes in climate may have an impact on the rainforest ecosystem, and consequently affect the feeding strategies of primates, however further research is required to determine if this is the case and the exact impacts this would have on the primates.

The Effectiveness Of Management Options In Reducing Human Disturbance To Wetland And Coastal Birds, Christopher Batey Dec 2013

The Effectiveness Of Management Options In Reducing Human Disturbance To Wetland And Coastal Birds, Christopher Batey

The Plymouth Student Scientist

Human disturbance to wildlife is a serious conservation issue for many groups of species. Birds inhabiting wetland and coastal environments may be of particular concern as they are exposed to disturbance both on land and on water, and due to growing pressure from tourism and leisure activities human disturbance in these environments may increase in the future. There are a wide variety of available management options referred to in the literature which aim to reduce or mitigate the negative impacts of disturbance to wetland and coastal birds. This review assesses the evidence for the effectiveness of these different management measures …

A Study Into The Impacts Of Water Table And Nitrogen Pulse On Cellulose Decomposition Rates And Carbon Release In Active Peatland, Matthew Culf

The Plymouth Student Scientist

Since the 1980s overstocking of sheep has become an increasing problem on UK uplands. This study examined the effect of livestock urination, and also water table depth, on active peatland on cellulose decomposition and fluvial carbon release. Urination was simulated using synthetic sheep urine (SSU) and applied to quadrats of active peatland at Redlake Mire on South Dartmoor and compared to quadrats without SSU treatment. Cellulose decomposition was measured using the cotton strip assay (CSA) method as a measure of microbial activity by examining a loss in tensile strength of cotton strips buried for 45 days from September 20th to …

An Audio Analysis Framework For Xna Developers, Stephen Hoult Dec 2013

An Audio Analysis Framework For Xna Developers, Stephen Hoult

The Plymouth Student Scientist

To those that are not specialists in the area, audio analysis can seem a daunting subject. This is particularly the case when creating software which draws upon the subject. There are many frameworks available which aid in the development of audio-driven software, yet few that cater to those with a limited knowledge of audio analysis. The aim of this project was to develop an audio analysis framework, specifically for implementation into C# XNA projects, which will enable developers with little to no understanding of audio analysis to develop audio-driven games. The result of this project has seen the completion of …

The Gating Charge Should Not Be Estimated By Fitting A Two-State Model To A Q-V Curve, Francisco Bezanilla, Carlos A. Villalba-Galea Dec 2013

The Gating Charge Should Not Be Estimated By Fitting A Two-State Model To A Q-V Curve, Francisco Bezanilla, Carlos A. Villalba-Galea

School of Pharmacy Faculty Articles

The voltage dependence of charges in voltage-sensitive proteins, typically displayed as charge versus voltage (Q-V) curves, is often quantified by fitting it to a simple two-state Boltzmann function. This procedure overlooks the fact that the fitted parameters, including the total charge, may be incorrect if the charge is moving in multiple steps. We present here the derivation of a general formulation for Q-V curves from multistate sequential models, including the case of infinite number of states. We demonstrate that the commonly used method to estimate the charge per molecule using a simple Boltzmann fit is not only inadequate, but in …

The Effects Of 8 Weeks Of Low Dose Supplementation Of Creatine And Sodium Bicarbonate On Exercise Performance, Amanda Jessica Morris Dec 2013

The Effects Of 8 Weeks Of Low Dose Supplementation Of Creatine And Sodium Bicarbonate On Exercise Performance, Amanda Jessica Morris

Master's Theses

Short-term (3-7 days), high doses of creatine (20g/d) and/or sodium bicarbonate (0.5g/kg body weight) supplementation increase exercise performance during short term high intensity activities; however, it remains unclear whether long-term, low doses of these supplements have a positive impact on exercise performance. The purpose of this study was to determine the effects of long-term (8 weeks), low dose creatine supplementation on exercise performance, and whether combining creatine and sodium bicarbonate supplementation has an additive effect. Sixty-three healthy, habitually active, adults (28 M, 35 W; 22+2 years; 23+ 3 BMI) were randomly assigned by sex to one of three supplement groups: …

Perfection: United Goal Or Divisive Myth? A Look Into The Concept Of Posthumanism And Its Theoretical Outcomes In Science Fiction, Rebecca Leah Mccarthy Dec 2013

Perfection: United Goal Or Divisive Myth? A Look Into The Concept Of Posthumanism And Its Theoretical Outcomes In Science Fiction, Rebecca Leah Mccarthy

Theses

As science races to keep up with science fiction, many scientists are beginning to believe that the next step in human evolution will be a combination of human and machine and look a lot like something out of Star Trek. The constant pursuit of perfection is a part of the human condition, but if we begin to stretch beyond the natural human form can we still consider ourselves human? Transhumanism and posthumanism are only theories for now, but they are theories that threaten to permanently displace the human race, possibly pushing it into extinction. This thesis will look at the …

Investigation Into The Effects Of Pegylation On The Thermodynamic Stability Of The Ww Domain, Sam S. Matthews Dec 2013

Investigation Into The Effects Of Pegylation On The Thermodynamic Stability Of The Ww Domain, Sam S. Matthews

Theses and Dissertations

The covalent attachment of poly(ethylene glycol) (PEG) to a protein surface (known as PEGylation), has been demonstrated to increase the serum half-life of therapeutic proteins by reducing kidney clearance and immunogenicity and by protecting against proteolysis. Theses beneficial effects could be further enhanced if PEGylation consistently increased protein conformational stability (i.e. the difference in free energy between the folded and unfolded states). However, the effects of PEGylation on protein conformational stability are unpredictable; PEGylation has been reported to increase, decrease, or have no effect on the conformational stability of medicinal proteins.This thesis details the results of two studies aimed at …

Mutiny Against The Mmpa: A Look At Alaska Sb 60, Garrett Boyle Dec 2013

Mutiny Against The Mmpa: A Look At Alaska Sb 60, Garrett Boyle

Alaska Law Review

In an attempt to curb the detrimental effects of a ballooning sea otter population, a new bill proposed in the Alaska State Senate seeks to amend the Alaska fish and game statutes by placing a bounty of $100 on sea otters lawfully taken by Alaska Natives. This Note studies the conflicting nature of the proposed bill, SB 60, with the current version of the Marine Mammal Protection Act, examining the enforceability of the provision in light of precedent from the Alaska Supreme Court and a liberal interpretation of the MMPA. The Note ultimately concludes that SB 60, as written, is …

The “Middle Place”: The Npr-A Impact Mitigation Program And Alaska’S North Slope, Shauna Woods Dec 2013

The “Middle Place”: The Npr-A Impact Mitigation Program And Alaska’S North Slope, Shauna Woods

Alaska Law Review

The communities of Alaska's North Slope increasingly find themselves in a "middle place," stuck between a past to which they cannot return and a future that is fraught with uncertainty. Oil and gas development on Alaska's North Slope has resulted in environmental, cultural, and social changes that have adversely affected the communities in the area. At the same time, oil and gas leasing in the National Petroleum Reserve in Alaska, located on the North Slope, has created an important revenue source for helping those communities mitigate the impacts of development and augment their capacities for addressing future changes. In particular, …
