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 Dec 2021

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 …

Shastri, Joseph Lombardo, Samantha C Okere, Stephanie Higgins, Brittany C Smith, Tiziana Deangelis, Ajay Palagani, Kamryn Hines, Daniel A. Monti, Stella Volpe, Edith P. Mitchell, Nicole L Simone

Department of Radiation Oncology Faculty Papers

Understanding metabolic and immune regulation inherent to patient populations is key to improving the radiation response for our patients. To date, radiation therapy regimens are prescribed based on tumor type and stage. Patient populations who are noted to have a poor response to radiation such as those of African American descent, those who have obesity or metabolic syndrome, or senior adult oncology patients, should be considered for concurrent therapies with radiation that will improve response. Here, we explore these populations of breast cancer patients, who frequently display radiation resistance and increased mortality rates, and identify the molecular underpinnings that are, …

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 …

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 …

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. …

Does Cannabidiol (Cbd) Oil Convert To Psychotropic Cannabinoids Including Tetrahydrocannabinol?, Danielle Young

The Plymouth Student Scientist

Cannabidiol (CBD) is a non-psychotropic cannabinoid that belongs to the Cannabis Sativa L plant. This naturally occurring cannabinoid has gained huge interest in recent years because of the potential therapeutic and pharmacological effects it has upon ingestion and inhalation. Cannabidiol has not only been regarded as a medicinal product but is widely sold over the counter (OTC) in the form of concentrated oils, food supplements, cosmetics, and electronic cigarettes. Regulation of OTC products has proven difficult because of the narcotic nature of the cannabis plant and it has been advised that CBD might be degraded into psychotropic cannabinoids, namely tetrahydrocannabinol …

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, …

Analysis Of Some Farm Driving Variables And Its Relation With Milk Production In A Pastoral Dairy Farm Of Buenos Aires, Argentina, J. L. Rossi, A. Ayala Torales, G. Acosta, V. A. Deregibus

IGC Proceedings (1977-2023)

The quantity of milk solids produced determines a dairy farm income and contributes to its profit. Total pasture production, forage quality and herd consumption are factors to be managed in this production system. The outcomes of two years were analyzed. Primary production showed its dependence on climatic conditions and use of technological inputs. Forage quality was promoted through interseeding legumes, applying fertilizer and maintaining the pasture young and leafy. Total forage removed by the herd was similar in both years although pasture production decreased. It was possible to cope with seasonal variations in forage production, by varying the grazing pressure …

Rotational Grazing Increases Wool And Lamb Production From Phalaris-Subterranean Clover Pastures In South Eastern Australia, A. N. Thompson, D. Borg, J. F. Graham, J. Lamb, G. R. Saul

IGC Proceedings (1977-2023)

Wool and lamb production from different grazing systems was compared in a Mediterranean environment near Hamilton in southeastern Australia. The grazing systems were based on combinations of fertiliser inputs and grazing methods that could promote the growth and persistence of phalaris (Phalaris aquatica) and increase animal production compared to ‘typical’ unimproved pastures. In the first 2 years of this experiment, the most productive systems more than doubled ewe stocking rate and wool production, and more than trebled lamb production per hectare, compared to ‘typical’ unimproved pasture, low fertility, set-stocked systems. The change to a well fertilised phalaris/subterranean clover …

Pathology Research and Scholarship

A key question in SARS-CoV-2 infection is why viral loads and patient outcomes vary dramatically across individuals. Because spatial-temporal dynamics of viral spread and immune response are challenging to study in vivo, we developed Spatial Immune Model of Coronavirus (SIMCoV), a scalable computational model that simulates hundreds of millions of lung cells, including respiratory epithelial cells and T cells. SIMCoV replicates viral growth dynamics observed in patients and shows how spatially dispersed infections can lead to increased viral loads. The model also shows how the timing and strength of the T cell response can affect viral persistence, oscillations, and control. …
