Mass Spectrometry-Based Proteomic Analysis To Characterise Barley Breeding Lines, Mahya Bahmani Jan 2023

Mass Spectrometry-Based Proteomic Analysis To Characterise Barley Breeding Lines, Mahya Bahmani

Theses: Doctorates and Masters

Barley is a key ingredient in the malting and brewing industry, and it is the fourth most important crop being cultivated worldwide. The protein content of the barley grain is one of the main components determining the quality and nutritive value of the food and beverages prepared from barley. Mass spectrometry-based proteomic analysis is a valuable tool that can guide and inform plant breeding strategies and crop improvement programs. Understanding the proteome changes in barley grain under different growing locations, the impact of different environmental conditions and its relationship with malting characteristics have the potential to inform breeding programs to …

Power Output Estimation Of A Two-Body Hinged Raft Wave Energy Converter Using Hf Radar Measured Representative Sea States At Wave Hub In The Uk, Daming Wang, Siya Jin, Martyn Hann, Daniel Conley, Keri Collins, Deborah Greaves

School of Engineering, Computing and Mathematics

For the physical model testing of wave energy converters (WECs) in the wave basin, it is necessary to test the models in a small number of sea states. Previously, the H – T binning method was widely used to determine the sea states that are representative of an ocean area. However, it omitted much useful information such as the wave directionality. In this paper, a novel method, the K-means clustering technique is used in combination with High Frequency (HF) radar measured data from Wave Hub, UK. The results show that K-means clustering method better preserves the characteristics of the ocean …

A Designed Two-Body Hinged Raft Wave Energy Converter: From Experimental Study To Annual Power Prediction For The Emec Site Using Wec-Sim, Siya Jin, Daming Wang, Martyn Hann, Keri Collins, Daniel Conley, Deborah Greaves

School of Engineering, Computing and Mathematics

The present study aims at providing more data and insights for the hinged type WEC, especially focusing on the two-body hinged raft WECs. Two WECs are considered: a well-studied generic hinged raft WEC (G-HRWEC) and a 1:25 scale designed hinged raft WEC (D-HRWEC). The open-source tool WEC-Sim is employed in numerical studies. Referring to the published numerical data for G-HRWEC, corrections are proposed to the WEC-Sim model which are shown to realise the ability of WEC-Sim to model the two-body hinged WEC. For the 1:25 scale D-HRWEC, the physical results show that the relative hinge motion between the rafts is …

Size Distribution, Elemental Composition And Morphology Of Nanoparticles Separated From Respirable Coal Mine Dust, Shoeleh Assemi, Lei Pan, Xuming Wang, Titilayo Akinseye, Jan D. Miller Jan 2023

Size Distribution, Elemental Composition And Morphology Of Nanoparticles Separated From Respirable Coal Mine Dust, Shoeleh Assemi, Lei Pan, Xuming Wang, Titilayo Akinseye, Jan D. Miller

Michigan Tech Publications, Part 1

Nanoparticles, defined as particles with one dimension below 100 nm, contribute little to the total mass concentration in respirable coal mine dust (RCMD) toxicological studies, but they could have a considerable part in the adverse health effects by RCMD inhalation. It has been shown that inhaled nanoparticles can penetrate deep into the lung and could plausibly contribute to acute and chronic pulmonary diseases by triggering oxidative stress formation and inducing inflammation. RCMD nanoparticles from samples collected in an underground mine in the United States were analyzed by a particle separation technique, field-flow fractionation (FFF), for size, morphology, and elemental composition. …


Modelling The Transmission Dynamics Of African Animal Trypanosomiasis; A Case Study Of Shimba Hills, Kwale County, Kenya, Gladys Jerono Rotich Jan 2023

Modelling The Transmission Dynamics Of African Animal Trypanosomiasis; A Case Study Of Shimba Hills, Kwale County, Kenya, Gladys Jerono Rotich

All Master’s Theses

African Animal Trypanosomiasis (AAT) is caused by parasites of the species Trypanosoma vivax, Trypanosoma congolense, and Trypanosoma rhodesiense. Of 48 sub-Saharan African nations, 36 have endemic cases of AAT. The disease is prevalent in savannah and woodland areas. It poses a major threat to livestock production and health in agro-pastoralist communities, many of which are located along the boundaries of wildlife reserves. Most epidemiological studies on AAT around Shimba Hills National Reserve (SHNR) have focused on the vectors (tsetse fly) and the host (cattle). No studies have been done to show how efficiently a trypanosome can be transmitted from tsetse …

ASEAN Journal on Science and Technology for Development

There have been many studies examining the processing of tapioca wastewater. However, most studies have only researched at a laboratory scale without considering whether the treatment is appropriate. The study's purpose is to compare the processing technology of biogas and liquid sugar using technical, environmental, social, and cost-benefit analysis criteria to determine the appropriate technology to be applied. Literature study, observation, and interviews were used to determine the characteristics of each criterion. Cost-benefit analysis is calculated using the R/C Ratio. Furthermore, priority determination is carried out using the Exponential Comparison Method (MPE) using assessments from environmental and industrial experts on …


Neighbor-Anchoring Adversarial Graph Neural Networks, Zemin Liu, Yuan Fang, Yong Liu, Vincent W. Zheng Jan 2023

Neighbor-Anchoring Adversarial Graph Neural Networks, Zemin Liu, Yuan Fang, Yong Liu, Vincent W. Zheng

Research Collection School Of Computing and Information Systems

Graph neural networks (GNNs) have witnessed widespread adoption due to their ability to learn superior representations for graph data. While GNNs exhibit strong discriminative power, they often fall short of learning the underlying node distribution for increased robustness. To deal with this, inspired by generative adversarial networks (GANs), we investigate the problem of adversarial learning on graph neural networks, and propose a novel framework named NAGNN (i.e., Neighbor-anchoring Adversarial Graph Neural Networks) for graph representation learning, which trains not only a discriminator but also a generator that compete with each other. In particular, we propose a novel neighbor-anchoring strategy, where …


Taurus: Towards A Unified Force Representation And Universal Solver For Graph Layout, Mingliang Xue, Zhi Wang, Fahai Zhong, Yong Wang, Mingliang Xu, Oliver Deussen, Yunhai Wang Jan 2023

Taurus: Towards A Unified Force Representation And Universal Solver For Graph Layout, Mingliang Xue, Zhi Wang, Fahai Zhong, Yong Wang, Mingliang Xu, Oliver Deussen, Yunhai Wang

Research Collection School Of Computing and Information Systems

Over the past few decades, a large number of graph layout techniques have been proposed for visualizing graphs from various domains. In this paper, we present a general framework, Taurus, for unifying popular techniques such as the spring-electrical model, stress model, and maxent-stress model. It is based on a unified force representation, which formulates most existing techniques as a combination of quotient-based forces that combine power functions of graph-theoretical and Euclidean distances. This representation enables us to compare the strengths and weaknesses of existing techniques, while facilitating the development of new methods. Based on this, we propose a new balanced …


Structural Impact Of Epstein-Barr Virus- Encoded Small Rna -1 On Its Transport And Function, Zubaida Hassan Jan 2023

Structural Impact Of Epstein-Barr Virus- Encoded Small Rna -1 On Its Transport And Function, Zubaida Hassan

Dissertations

Epstein-Barr Virus (EBV)-Encoded RNAs (EBERs) are two small, noncoding, structurally conserved transcripts that are expressed in millions of copies in all stages of EBV infection. Despite their abundant expression, the role of EBERs in EBV biology or pathogenesis is not well defined. However, they are associated with driving cell proliferation and improving intercellular communication via their secretion in exosomes. In spite of the pathogenic potentials of EBERs, the mechanisms involved in their transport and function remain to be elucidated. The aim of this PhD dissertation was to investigate the structural impact of EBER1 in its transport and function. The conserved …
