A Novel High Yield Process For Gold Sulfide Nanoparticle Synthesis Via Shifting Equilibrium Of Self-Assembly Reaction., Dhruvinkumar Patel Dec 2012

A Novel High Yield Process For Gold Sulfide Nanoparticle Synthesis Via Shifting Equilibrium Of Self-Assembly Reaction., Dhruvinkumar Patel

Electronic Theses and Dissertations

Gold nanoparticles (AuNPs) have attracted enormous attention in the field of nanotechnology for applications such as, immunoassay, drug delivery, contrast enhancement and tumor therapy. The typical range of gold nanoparticles varies from 1– 150 nm; there are many different subtypes of AuNPs mainly based on size, shape, and optical properties including: gold nanospheres, nanorods, nanocages, and nanoshells. The main advantage of using gold nanoparticles is the large surface-to-volume ratio; this will allow the particles to be functionalized with drugs and/or targeting agents to create many novel applications. Many AuNPs have another advantage as well, they can be fabricated to either …

Egypt's Police State In The Work Of Idris And Mahfouz, David F. Dimeo Dec 2012

Egypt's Police State In The Work Of Idris And Mahfouz, David F. Dimeo

CLCWeb: Comparative Literature and Culture

In his article "Egypt's Police State in the Work of Idris and Mahfouz" David F. DiMeo examines how two leading twentieth-century authors of politically committed fiction addressed an angry generation's confrontations with former members of the oppressive state police apparatus. Yusuf Idris's The Black Policeman (1962) and Najib Mahfouz's al-Karnak (1974) remain particularly relevant as today's Egyptian activists confront the vestiges of the former regime's security forces. Using Mikhail Bakhtin's theory of the carnival as a paradigm for analysis, DiMeo examines how both texts present sharp contrasts between hollow quests for public revenge through purges and a genuine overturning of …

Victims Of The City In Novels Of Zola And Dostoevsky, Marta L. Wilkinson Dec 2012

Victims Of The City In Novels Of Zola And Dostoevsky, Marta L. Wilkinson

CLCWeb: Comparative Literature and Culture

In her article "Victims of the City in Novels of Zola and Dostoevsky" Marta Wilkinson argues that urbanity in its nineteenth-century setting functioned as the culpable agent in criminal behavior found in Dostoevsky's Crime and Punishment and in several of Zola's Rougon-Macquart novels. Wilkinson an analysis of the novels based on Merlin Coverly's concept of psychogeography which supports the extension of the cityscape as an integral part of the novels' characters. Further, Wilkinson illustrates how in Zola's and Dostoevsky's novels the city reigns triumphant as characters fall victim to disease, drink, or are left with desperate choices: in Dostoevsky's novel …

Development Of Algorithms And Criteria For Continuous Condition Monitoring Of Railroad Bearings, Sean Michael Woods Dec 2012

Development Of Algorithms And Criteria For Continuous Condition Monitoring Of Railroad Bearings, Sean Michael Woods

Theses and Dissertations - UTB/UTPA

This thesis summarizes research conducted at the University of Texas-Pan American to investigate the implementation of condition monitoring algorithms for use with railway roller bearings equipped with wireless temperature sensor nodes. Current temperature based condition monitoring techniques utilize wayside detection equipment intermittently located along the track to garner sporadic bearing cup temperatures. Such devices are not capable of detecting brief transient temperature trending events. The developed algorithms were tested using a fleet of ten railway freight cars instrumented with wireless sensor nodes and operated by an Australian freight transportation company. Eighteen months of continuous monitoring combined with the inspection of …

Human Papillomavirus, Vaccines, And Protection From Cervical Cancer, Sadiman K. Altinbas, Omer L. Tapisiz Dec 2012

Human Papillomavirus, Vaccines, And Protection From Cervical Cancer, Sadiman K. Altinbas, Omer L. Tapisiz

Saudi Medical Journal

Current published data makes clear the relationship between genital human papillomavirus (HPV) infection and cervical cancer. Although there is an opportunity for screening programs that could obviate the disease, cervical cancer still remains the second most common cancer among women worldwide. The subtypes HPV 16 and 18 affect the anogenital tract mucosal surfaces, and accounts for nearly 70% of all cervical cancers, and 90% or more of anal cancer cases. When the 493,000 new cases of cervical cancer and 274,000 deaths per year are taken into consideration, the importance of treatment and prophylaxis modalities for HPV can clearly be recognized. …

Permaculture And Public Health: Mitigation Of The Lifestyle Risk Factors For Type 2 Diabetes Through The Establishment Of Permaculture Edible Forest Gardens, Brett Christopher Lehner Dec 2012

Permaculture And Public Health: Mitigation Of The Lifestyle Risk Factors For Type 2 Diabetes Through The Establishment Of Permaculture Edible Forest Gardens, Brett Christopher Lehner

Honors Scholar Theses

Over the past thirty years, the incidence of type 2 diabetes and obesity has greatly increased in the United States. This paper compares the living environment of hunter-gathers to that of modern humans, in diet and activity levels, and discusses the recent increase of type 2 diabetes as a 'disease of civilization'. To address these changes in dietary composition and activity levels, an alternative agricultural model, permaculture edible forest gardening, is proposed. Permaculture edible forest gardening is an agricultural model which mimics natural ecosystem structure while consisting of entirely edible, perennial plant species. Permaculture edible forest gardens can potentially play …

Fluorescent Proteins And Chromoproteins In Phylum: Cnidaria, Mario Lewis Dec 2012

Fluorescent Proteins And Chromoproteins In Phylum: Cnidaria, Mario Lewis

The Plymouth Student Scientist

Green fluorescent protein was first discovered in Aequorea victoria. Its significance in a continually expanding range of scientific applications led to the discovery of an abundance of homologous fluorescent proteins and non-fluorescent chromoproteins in a variety of species in the phylum Cnidaria. The document reviews the various proposed hypotheses on the biological functions and biochemistry of fluorescent proteins and chromoproteins, wherein a full resolution remains elusive and is the subject of on-going debate. Mutagenesis has provided novel variants and insights into the relationship between the spectral characteristics and chromophore structures of fluorescent proteins that encompass the visible spectrum. Fluorescent proteins …

Effects Of Algal Toxicity On The Clearance Rate Of The Blue Mussel (Mytilus Edulis), Samantha Bowgen Dec 2012

Effects Of Algal Toxicity On The Clearance Rate Of The Blue Mussel (Mytilus Edulis), Samantha Bowgen

The Plymouth Student Scientist

The purpose of this study was to investigate the effect of toxic strains of Karlodinium veneficum on the clearance rate of Mytilus edulis. Suspensions of the toxic strain and the non-toxic strain of K. veneficum, mixed with an alternative non-toxic species, Prorocentrum micans, were made and performed as parallel experiments in order to compare their effects on clearance rate. Clearance rate was measured by taking samples from suspensions every five minutes up to 30 minutes, and counting the algal cells found within each sample using a Sedgewick rafter slide. No significant difference was found between the two experiments (F (9.322, …

Investigation Of The Vasorelaxant Properties Of Nitroxyl During Altered Glycaemic Conditions, Kimberley Sams Dec 2012

Investigation Of The Vasorelaxant Properties Of Nitroxyl During Altered Glycaemic Conditions, Kimberley Sams

The Plymouth Student Scientist

Nitroxyl (HNO) is currently a vasorelaxant of high interest, but as yet its mechanisms of action have not been fully elucidated. It is thought that HNO acts on KV channels to mediate vasorelaxation, and this has been shown in previous studies (Irvine et al, 2003; Favarolo & Kemp-Harper, 2009; Yuill et al, 2011). It has also been shown that high levels of glucose inhibit KV channels (Rainbow et al, 2006) so would inhibit HNO mediated relaxation. This study could provide further evidence of KV involvement of HNO mediated vasodilation. This study uses a temperature controlled organ bath with aortic ring …

The Effect Of Itgd Sensitivity And Contact On Attitudes Towards Burqas, Sophie Augarde Dec 2012

The Effect Of Itgd Sensitivity And Contact On Attitudes Towards Burqas, Sophie Augarde

The Plymouth Student Scientist

The presented research investigates whether intergroup disgust sensitivity (affect-laden construct reflecting individual differences to experience revulsion towards outgroups) predicts greater prejudicial attitudes towards burqas. In addition to investigating the effect of ITGD sensitivity on prejudicial attitudes, types of contact (no contact, imagined contact and physical contact) between participants and an outgroup member were investigated to assess the efficacy of reducing prejudice towards women who wear burqas. ITGD sensitivity along with attitude towards burqas was measured over two sessions. Results indicated that there was no statistically significant effect of ITGD sensitivity or contact type on attitudes towards burqas. However, mean score …

The Conservation Biology And Ecology Of The African Leopard Panthera Pardus Pardus, Ross Tyzack Pitman Dec 2012

The Conservation Biology And Ecology Of The African Leopard Panthera Pardus Pardus, Ross Tyzack Pitman

The Plymouth Student Scientist

The African leopard Panthera pardus pardus is an apex predator, and a reliable indicator of a healthy ecosystem. Currently assessed as ‗near threatened‘ by the IUCN Red List of Threatened Species, leopards are exposed to a range of threats that include: habitat loss and/or degradation, depletion of natural prey, conflict with people, consumptive- and non-consumptive practices, and the illegal trade of leopard products. Leopards have disappeared from 37% of their historical range, and are continuing to decline. Leopards have been extirpated across many areas of Africa, especially where people are densely populated, which has left patchily distributed leopard populations throughout …

Facies Analysis And Diagenesis Of Late Pleistocene Shoreline Sands, Saunton, North Devon, Sophie Young Dec 2012

Facies Analysis And Diagenesis Of Late Pleistocene Shoreline Sands, Saunton, North Devon, Sophie Young

The Plymouth Student Scientist

The succession at Saunton is composed of all the major elements of Pleistocene coastal stratigraphy from across north Devon. The aim of this study is to analyse and interpret the depositional environment of the laterally variable late Pleistocene sedimentary succession at Saunton, using facies analysis. This knowledge is used to infer local relative sea level changes from patterns of transgressions, normal, and forced regressions and an attempt is made, using sequence stratigraphy, to constrain the relative ages of the deposits based on marine oxygen isotope stages. Petrographic observations of the different facies and grain types are used to evidence the …

Biologging Science: Advances In Our Knowledge Of Seabirds And Their Behaviours, David Evans Dec 2012

Biologging Science: Advances In Our Knowledge Of Seabirds And Their Behaviours, David Evans

The Plymouth Student Scientist

The use of miniature tags attached to free-living animals to record data is termed ‘biologging’. This procedure has been used to study seabirds since the 1970’s and our knowledge of their behaviour, physiology and migration has advanced through the decades, along with the potential for conservation of species. Technological advances in recent years have improved data resolution and storage, enabling a better understanding of seabirds and their environment

The Effects Of Logging And Fragmentation On Bird Diversity, Bethany Mccarthy Dec 2012

The Effects Of Logging And Fragmentation On Bird Diversity, Bethany Mccarthy

The Plymouth Student Scientist

Deforestation and forest degradation is occurring globally at an alarming rate. The annual net loss of forest cover has been reduced in the past decade through sustainable forest management and conservation measures. Despite this, the remaining forest is becoming increasingly degraded with the total area of primary forest declining. Avian diversity has been shown to decline in degraded and fragmented forests due to logging activities. In this review the impacts of logging on avian communities are assessed by comparing diversity between primary forest and degraded secondary forest, industrial plantations and forest fragment sizes. The major organisations and current initiatives that …

The Positive Effects Of Aquarium Visits On Children's Behaviour: A Behavioural Observation, Hazel Cocker Dec 2012

The Positive Effects Of Aquarium Visits On Children's Behaviour: A Behavioural Observation, Hazel Cocker

The Plymouth Student Scientist

To date research has found a positive effect of blue spaces on adults’ wellbeing. However, it remains to be seen whether these findings are also true for children. The present study aims to address this gap in the literature. The researchers observed children’s behaviour at the National Marine Aquarium across two weeks, including one where the Big Draw event was taking place. In line with restorative theories of natural environments (Kaplan, 1995, Ulrich, 1983), the current research found the exhibit had a calming effect on behaviour and increased levels of happiness across both weeks. During the Big Draw week children …

Analyses Of Captive Behaviour And Enclosure Use In Rothschild Giraffes (Giraffa Camelopardalis Rothschildi) Housed At Paignton Zoo Environmental Park ®, Sarah Garry Dec 2012

Analyses Of Captive Behaviour And Enclosure Use In Rothschild Giraffes (Giraffa Camelopardalis Rothschildi) Housed At Paignton Zoo Environmental Park ®, Sarah Garry

The Plymouth Student Scientist

It has been suggested that wild herbivorous animals, like the Rothschild Giraffe (Giraffa camelopardalis rothschildi), are difficult to house in captivity due to their natural wide home range and specialised diet. The aim of this study was to understand what influence the design of the giraffe enclosure at Paignton Zoo has on the activity budget of the Rothschild Giraffes (Giraffa camelopardalis rothschildi) housed in it, in relation to enclosure use and the performance of a natural behavioural repertoire. This was achieved by observing the giraffe’s behaviour and location when in the enclosure, both indoors and outdoors. The Spread of Participation …

Conservation Genetics Of A Spotted Salamander (Ambystoma Maculatum (Shaw 1802)) Local Population In Southeast Tennessee, Daniel Scott Armstrong Dec 2012

Conservation Genetics Of A Spotted Salamander (Ambystoma Maculatum (Shaw 1802)) Local Population In Southeast Tennessee, Daniel Scott Armstrong

Masters Theses and Doctoral Dissertations

Currently there is a worldwide amphibian decline with numerous causes. Because of this, it is important to understand how genetic variation in local amphibian populations is affected by disturbance. The goal of this study was to assess the genetic impacts of past chemical and ammunition storage and present industrialization on a local population of Ambystoma maculatum (Shaw 1802) using thirteen microsatellite markers. Most loci exhibited no loss of heterozygosity but the low effective population size may indicate vulnerability to future declines. No population substructure or sex-biased dispersal was detected. Possible explanations for the reduction in genetic diversity at four loci …

Mortality Salience And Worldview Defense, Toni Brooke Merkey Dec 2012

Mortality Salience And Worldview Defense, Toni Brooke Merkey

Dissertations

Research generated from Terror Management Theory has demonstrated that reminding participants of their eventual death increases self-esteem striving and worldview defense (Pyszczynski, Greenberg, Solomon, Arndt, & Schimel, 2004). The hypothesis in the present study is that individuals higher in emotion dysregulation will engage in higher levels of worldview defense than those lower in emotion dysregulation. This hypothesis was based on the assumption that individuals high in emotion dysregulation will have a greater need to regulate their emotions by engaging in worldview defense after being asked to think about their own death than will non-emotionally dysregulated individuals. To test this hypothesis, …
