Dielectric Relaxation Studies Of Hydrogen Bonded Complexes Of Benzamide And Acetamide With Halogenated Phenols Using X-Band Microwave Frequency, Basha A. Aathif, Khan F. Liakath Ali

ASEAN Journal on Science and Technology for Development

At 308 K, using a 9.37 GHz dielectric relaxation setup, dielectric studies of hydrogen bonded complexes of benzamide and acetamide with 4-fluorophenol, 4-bromophenol, 4-chlorophenol, and 4-iodophenol in benzene were performed. Various dielectric parameters (such as ?', ?'', ?0, ??) were tested. The steric interactions of the proton donor determined the group rotation relaxation time t(2), whereas the significance of the single frequency method of Higasi et al. for multiple relaxation time t(1) was determined by the hydrogen bonding power of the phenolic hydrogen. The presence of a 1:1 complex system between the prepared samples, as well as a charge transfer …

High Expression Of Glycolytic Genes In Clinical Glioblastoma Patients Correlates With Lower Survival, Kimberly M. Stanke, Carrick Wilson, Srivatsan Kidambi

Department of Chemical and Biomolecular Engineering: Faculty Publications

Glioblastoma (GBM), the most aggressive brain tumor, is associated with a median survival at diagnosis of 16–20 months and limited treatment options. The key hallmark of GBM is altered tumor metabolism and marked increase in the rate of glycolysis. Aerobic glycolysis along with elevated glucose consumption and lactate production supports rapid cell proliferation and GBM growth. In this study, we examined the gene expression profile of metabolic targets in GBM samples from patients with lower grade glioma (LGG) and GBM. We found that gene expression of glycolytic enzymes is up-regulated in GBM samples and significantly associated with an elevated risk …

Spontaneous Visual Perspective-Taking: Level 2 Representations Of Another's Perspective Are Not Related To What They Actually See, Louis Aldrich Dec 2021

Spontaneous Visual Perspective-Taking: Level 2 Representations Of Another's Perspective Are Not Related To What They Actually See, Louis Aldrich

The Plymouth Student Scientist

The ability to understand what another person can see is a fundamental feature of human interaction, commonly referred to as ‘visual perspective-taking’ (VPT). Traditionally, this ability has been conceptualised along two ‘levels’, in line with developmental observations (Flavell, Everett, Croft & Flavell, 1981). ‘Level-1 VPT’ is a simple, automatic, and rapid process enabling understanding of what another individual can see. In contrast, ‘Level-2 VPT’ is a more complex process requiring conscious control, which enables understanding of how features of the environment look from another’s location. This has led to a widely accepted hypothesis that Level-1 VPT is necessary in the …

Who Owns These Objects? - Impact Of Social And Personal Conditions On Self-Prioritisation, Sammy Parkin Dec 2021

Who Owns These Objects? - Impact Of Social And Personal Conditions On Self-Prioritisation, Sammy Parkin

The Plymouth Student Scientist

A relatively new development concerning literature pertaining to the concept of self-bias has highlighted that humans tend to self-prioritise when completing tasks based on perceptual judgements (the self-prioritisation effect). Since then, further exploration into the role that other tasks can have on this effect have been demonstrated, including the idea that object-ownership tasks show the same effects (Golubickis et al., 2018). As recent focus has been on the association between this effect and the task used, it means that there has been little exploration into the possible role that other variables have on predicting levels of self-prioritisation. Based on this, …

Using Remote Sensing Techniques To Investigate The Detection Of Sargassum Blooms In The Caribbean And Possible Causes For These Events, Louise Ely Dec 2021

Using Remote Sensing Techniques To Investigate The Detection Of Sargassum Blooms In The Caribbean And Possible Causes For These Events, Louise Ely

The Plymouth Student Scientist

Sargassum was thought to originate from a single source, the Sargasso Sea in the central west Atlantic. This has been challenged over the past decade after excessive amounts of the macroalgae began washing up on Caribbean coastlines in June 2011, leading the scientific community to investigate causes of this phenomenon. These, now yearly, events are having detrimental environmental and socioeconomic impacts in areas of the Caribbean and central America, providing motivation for uncovering any regime shifts or severe changes in anthropogenic activity. Anthropogenic sources of nitrate from three rivers surrounding the CWA in addition to wind stress and chlorophyll-a levels …

Handedness: Does It Affect Interhemispheric Transfer?, Diyotima Datta Dec 2021

Handedness: Does It Affect Interhemispheric Transfer?, Diyotima Datta

The Plymouth Student Scientist

Left- handed people have different patterns of cerebral dominance to the rest of the population, as explained by Annett’s (1996) right shift theory. Left handers are considered to have bilateral functionality unlike right handers who have left cerebral dominance, which is believed to lead to faster interhemispheric transmission time in left- handers. The current research examined the effect of handedness on interhemispheric transfer time. The study was conducted online using fifty-one left and fifty-one right handers classified by laterality quotients obtained from Oldfield’s (1971) 12 item Edinburgh Handedness Inventory. The crossed uncrossed difference was calculated using mean reaction times yielded …

Constrained Portfolio Optimisation, Mohammad Alam Tahir Dec 2021

Constrained Portfolio Optimisation, Mohammad Alam Tahir

The Plymouth Student Scientist

Portfolio optimisation is an important problem in finance; it allows investors to manage their investments effectively. This paper considers finding the efficient frontier associated with the mean-variance portfolio optimisation (unconstrained) problem. We then extend the mean-variance model to include cardinality constraints (resulting in an NPHard problem) that limits the number of assets in a portfolio. We discuss different types of algorithms that one can use for finding the optimal portfolios, implementing a meta-heuristic genetic algorithm technique to solve the unconstrained and cardinality constrained problems. Finally, we improve our solutions by altering the crossover and mutation probabilities in the genetic algorithm …

The Extent To Which Autistic Traits Are Predictive Of Impairments In Allocentric Spatial Navigation, Amber Presley Dec 2021

The Extent To Which Autistic Traits Are Predictive Of Impairments In Allocentric Spatial Navigation, Amber Presley

The Plymouth Student Scientist

This research is centred around how individuals with autistic traits navigate using both allocentric and egocentric spatial reference frames. Previous research suggests differences in the way that those with Autistic Spectrum Disorder (ASD) navigate with much research indicating that those with ASD struggle particularly with allocentric navigation. In this study, 256 participants completed a place learning task followed by two self-report questionnaires, the Navigation Inventory and the Autism Spectrum Quotient (AQ). Results showed that AQ scores correlated with better performance in the allocentric condition of the place learning task, this was in the opposite direction than predicted. Further to this, …

The Dark Tetrad Of Personality And The Tendency To Engage In Revenge Porn, Niamh Thomason-Darch Dec 2021

The Dark Tetrad Of Personality And The Tendency To Engage In Revenge Porn, Niamh Thomason-Darch

The Plymouth Student Scientist

Revenge porn is an increasing and pervasive phenomenon. Despite this, the knowledge and understanding of this behaviour is limited, especially the psychological characteristics of perpetrators of revenge porn. The Dark Tetrad of personality: Machiavellianism, psychopathy, narcissism, and sadism, has been associated with a range of antisocial behaviours. Recent research indicates a relationship between the Dark Tetrad and revenge porn proclivity. The present study extended these findings by investigating the relationship between revenge porn proclivity and the Dark Tetrad using more trait-specific measures. A community sample of 306 participants, aged 18-77, were recruited online. Participants completed a series of personality measures …

Public Perceptions Of Indecent Image Offenders, Joshua Samuel Taylor-Smith Dec 2021

Public Perceptions Of Indecent Image Offenders, Joshua Samuel Taylor-Smith

The Plymouth Student Scientist

Indecent images of children (IIOC) offences are on the rise year by year, in part due to the easy accessibility to this content with the augmentation of the internet. This has led to increased attention from the public and those involved with law enforcement. However, research into the public perceptions of these offences is very limited. While they do not directly dictate law enforcement, the views of the public have become dominant in penal policymaking and therefore, understanding their current perceptions and beliefs is paramount. One of the only items of research into this area was conducted by Lam et …

How Do Personality Traits Influence The Experience Of Positive Emotions?, Elenie Shotton Dec 2021

How Do Personality Traits Influence The Experience Of Positive Emotions?, Elenie Shotton

The Plymouth Student Scientist

Neuroticism is a personality trait known to be associated with negative emotions (Tellegan, 1985), but little is known about how it affects the experience of positive emotions, and more specifically, hope. Positive emotions can have long lasting effects on well-being, by broadening thought-action repertoires and undoing lingering negative emotions (Frederickson, 1998). Cognitive strategies strongly influence state positive emotions in individuals low in neuroticism, but have no effect on those with high neuroticism (Ng & Diener, 2009). We expected individuals high in neuroticism would experience a smaller increase in state hope following hope emotion induction. Participants completed an online survey involving …

The Effect Of Onshore Wind On Wave Overtopping Of A Vertical Sea Wall, Sarah Durbridge Dec 2021

The Effect Of Onshore Wind On Wave Overtopping Of A Vertical Sea Wall, Sarah Durbridge

The Plymouth Student Scientist

Strong winds can produce overtopping rates that are considerably higher than predicted by the EurOtop formulae, which do not make provision for wind. However, no detailed industry guidance exists about the quantification of those wind effects. Physical modelling tests (scale 1:21) investigated how the mean rate of overtopping changed with wave frequency under the influence of various wind speeds. The nature and quantity of overtopping was found to be strongly related to the frequency of the incident wave. The wind had a significant effect on the mean overtopping rate, with the most pronounced effect occurring when the overtopping was at …

Variability In Epifaunal Assemblages Between Sargassum Muticum And Zostera Marina: A Functional Group Approach, Jenny Hickman

The Plymouth Student Scientist

Marine macrophytes are globally important to coastal ecosystems, providing refugia, nutrients and important ecological processes. The structure and composition of macrophytes have a bottom-up effect on the epifauna they support. Due to their wide-reaching effects, invasive algae are considered one of the greatest threats facing marine ecosystems. Sargassum muticum is a Japanese algae increasing its non-native range in coastal habitats globally. A highly dispersive algae, able to colonise soft substratum, it is considered a threat to seagrass beds across the North East Atlantic. In Salcombe Estuary, Devon, beds of Zostera marina have seen increasing levels of invasion by S. muticum. …

Exploring The Minimum Number Of Trials Needed To Accurately Detect Concealed Information Using Eeg, Rhian Graham Dec 2021

Exploring The Minimum Number Of Trials Needed To Accurately Detect Concealed Information Using Eeg, Rhian Graham

The Plymouth Student Scientist

Deception can have serious consequences, therefore detection methods such as the Electroencephalogram (EEG) are vital. However, they can be perceived as time-consuming thus causing limited usage. The purpose of this study was to discover the minimum number of trials needed to accurately detect deception. It was hypothesised that accuracy would increase with number of trials (due to reduced effects of noise) but would then fall (due to subject’s fatigue). Due to the Coronavirus, this study was restricted to 9 participants within our ‘Lab Bubble’ of third-year Psychology students at the University of Plymouth. A Concealed Information Test (CIT) was conducted, …
