An evaluation of nutrition welfare policies for low-income children in the United Kingdom
Creators: name: Parnham, Jennie
Publisher: name: Imperial College London
Year: 2021

description: Introduction A child’s socioeconomic status is one factor determining their dietary quality. Food-assistance policies in the UK include Healthy Start and Universal Infant Free School Meals (UIFSM). Around 17% of the population are eligible for these policies, yet uptake can be as low as 55%. However, they are under-evaluated and consequently, not well-understood. This thesis aims to evaluate these nutrition welfare policies on measures of dietary intake in British children. Methods In this thesis, I quantitively analyse nationally representative datasets to evaluate a range of food assistance policies, including Healthy Start and UIFSM. Multivariable regression methods were used to test how programme participation impacted the dietary intake in UK children. Indicators used to describe the impact of the policies on dietary intake included household purchases, nutrient and food content and degree of industrial food processing in the diet. Results Overall, I demonstrated mixed impacts of the food-assistance policies on the dietary intake of children. For instance, I did not find evidence that Healthy Start participation was associated with increased fruit and vegetable expenditure. Yet, I found that UIFSM was associated with lower national intakes of ultra-processed foods associated with packed lunches, contributing to lower sodium and saturated fat intakes. Furthermore, UIFSM was associated with lower socioeconomic dietary inequities. However, although school meals were preferable to packed lunches in this analysis, they were not optimal, with high levels of processed and sugary items. Conclusions Food-assistance policies in the UK have the potential to improve the diet of not only low-income children, but all children through universal schemes. However, improvements need to be made to realise their full potential. Key recommendations include broadening the age and income eligibility criteria of Healthy Start and Free School Meal policies, so they reach more of the population and ensure continuity of assistance throughout childhood.

description: The effects of mutual Coulomb interactions between Dirac fermions in monolayer graphene on the Hofstadter energy spectrum have been studied. Our studies indicate that the effects of the interaction depend strongly on the amplitude of the periodic potential. For large amplitudes the interaction effects are small and the properties of the system are primarily determined by the periodic potential but for small amplitudes the interaction greatly influences the band gap. The signature of the interaction effects in the Hofstadter system can be probed through magnetization where the Coulomb effects are dominant for small amplitudes of the periodic potential.

Novel MRI techniques in the diagnosis of musculoskeletal infection in children
Creators: name: Alavi, Afshin
Publisher: name: Imperial College London

description: Abstract Introduction: Musculoskeletal infections in children are common and if not adequately treated can result in poor prognoses. Early diagnosis and rapid treatment are crucial. The clinical and laboratory results are often non-conclusive or misleading. Radiology has always played a part in the diagnosis of Paediatric musculoskeletal infections. MRI is the most sophisticated MSK imaging tool and advanced MRI protocols with tailored techniques can improve the diagnostic yield of MRI in Paediatric MSK infection. Methods: 99 children with acute MSK pain and signs of infection were prospectively recruited. Each patient had a MRI scan on the first day of admission. A tailored MRI protocol was utilised, consisting of structural and biodynamic (DWI & SCE) sequences. Two consultant MSK radiologists independently analysed the scans and completed evaluation forms consisting of qualitative and semi-quantitative questions. The quantitative data from DWI and SCE sequences were separately analysed.Results: 103 MRI scans were performed. 3 scans were excluded due to incomplete protocols. 5 quantitative DWI and 3 SCE analyses were excluded due to irregularities of the values. The most common clinical diagnosis was infection. The feasibility of the protocol was excellent. The accuracy of the MRI protocol was good-excellent. The most accurate sequence was SCE. The diagnostic accuracy of the readers was good compared to an agreed gold standard. The most valued sequence by the readers for the diagnostic process was SCE. There were no relevant statistical thresholds for ADC and most of permeability values except for one regarding MSK infection. Conclusion: The tailored MRI protocol of the study is a feasible diagnostic tool with high level of diagnostic accuracy for paediatric MSK infections. The advanced MRI techniques in this study are the strengths of the protocol, which have demonstrated high accuracy and subjective diagnostic confidence. The quantitative values of the biodynamic sequences are promising parameters which need further evaluation in future studies.
NEURAL ROSETTES FORMATION AS A NEWLY EMERGENT HUNTINGTIN FUNCTION
Creators: name: LO SARDO, VALENTINA
Publisher: name: Universit� degli Studi di Milano
Year: 2010

description: Huntingtin is a large, ubiquitous, partially unknown protein, in which mutation in its N-terminus is the cause of genetic, neurodegenerative disease called Huntington Disease. Although the presence of mutated huntingtin, from one decade it is known that the loss of wild-type protein can contribute to pathogenesis of HD (Cattaneo et al 2000). Huntingtin is embryonic lethal during embryogenesis and it exerts a fundamental role in the adult brain as a protein sustaining viability and health of mature neurons. Huntingtin is shown to be involved in neuron viability and maintenance, but its really and univocal function is already unknown. This study, object of my PhD project is focused on understand normal huntingtin function. Firstly, through a bioinformatic study by multialignment of 17 different homologues of huntingtin, both in deuterostome and protostome branches, we dissect the primary aminoacid sequence of huntingtin to reveal the presence of protein domains. The C-terminal portion of the protein proved to be conserved during evolution, while the N-terminal tract exhibited more recent evolution of the sequence. Moreover, look at the particular evolution and specification of the nervous system structures, and complexity along deuterostomes, we speculate that the evolution of the primary huntingtin aminoacid sequence parallels the particular evolution of the nervous system. In this view huntingtin could have evolved during phylogenesis a particular neural function. Furthermore, we study the role of normal huntingtin since its early embryonic function, in particular during the early phases of neural development, by using embryonic stem cell model. To dissect how this function is acquired during phylogenesis we choose to study neural differentiation process and the activity of the N-terminal domain during neurulation. We demonstrated that: i) huntingtin has a key role in the formation of neural tube-like rosettes, since its absence lead to a severe disorganization of neural precursors cells. ii) This defect is due to an impaired cell-cell adhesion mechanism, mediated by N-cadherin. iii) This function has emerged during deuterostomes evolution and it is exerted by the huntingtin N-terminal domain.
A study of Chief Executive Officer (CEO) turnover in Vietnam: The link between firm performance and CEO turnover

description: In general, CEO turnover has been researched widely following numerous studies in developed countries. Nevertheless, the determinants of CEO turnover are still unclear in transition countries of which the legal and regulatory framework are weak and financial systems and corporate governance are underdeveloped. Therefore, examining determinants of CEO turnover in Vietnam, a transition country, helps to provide more evidence on the efficiency and effectiveness of corporate governance in transition countries. Furthermore, the examination helps to define weaknesses, and it, therefore, could provide guidance to improve corporate governance in Vietnamese enterprises. Particularly, the thesis investigates the CEO turnover in Vietnam following the research philosophy of positivism paradigms and deductive approach. Further, it implied logistics regression in order to evaluate the influences of factors on CEO turnover in Vietnamese-listed enterprises. The sample of the thesis, including 156 listed firms at the end of 2006 in Hanoi and HoChiMinh Securities Centres, 780 firm-year observations have been conducted. Among 780 observations, there are 88 CEO turnovers occurred during the observed period from 2006 to 2010. The main findings of the thesis show that firm performance had significant inverse relationship with the likelihood of CEO turnover. Meanwhile, the influence of ownership structure on CEO turnover was insignificant. Interestingly, aged CEOs in Vietnamese-listed enterprises were more likely to be dismissed than young CEOs. Additionally, the probability of CEO turnover significantly increased when CEOs reached the ages of 59-61. The certain age also reduced the influence of CEO duality on CEO turnover. Together, CEO ownership negatively influenced the sensitivities of the link between firm performance and CEO turnover, although the influence is insignificant when CEOs own less than 5% of firm shares. Importantly, the thesis provides the significant and positive relationship between the percentage of independent directors and CEO turnover. Based on those findings, the thesis concludes that the efficiency of corporate governance and effectiveness of management are able to improve by increasing the independence of the Board of Management rather than other factors.

description: A non-commutative, planar, Hopf algebra of rooted trees was proposed in L. Foissy, Bull. Sci. Math. 126 (2002) 193-239. In this paper we propose such a non-commutative Hopf algebra for graphs. In order to define a non-commutative product we use a quantum field theoretical (QFT) idea, namely the one of introducing discrete scales on each edge of the graph (which, within the QFT framework, corresponds to energy scales of the associated propagators).

description: The mechanical behavior of crystals is dominated by dislocation networks, their structure and their interactions with impurities or thermal phonons. However, in classical crystals, networks are usually random with impurities often forming non-equilibrium clusters when their motion freezes at low temperature. Helium provides unique advantages for the study of dislocations: crystals are free of all but isotopic impurities, the concentration of these can be reduced to the ppb level, and the impurities are mobile at all temperatures and therefore remain in equilibrium with the dislocations. We have achieved a comprehensive study of the mechanical response of 4He crystals to a driving strain as a function of temperature, frequency and strain amplitude. The quality of our fits to the complete set of data strongly supports our assumption of string-like vibrating dislocations. It leads to a precise determination of the distribution of dislocation network lengths and to detailed information about the interaction between dislocations and both thermal phonons and 3He impurities. The width of the dissipation peak associated with impurity binding is larger than predicted by a simple Debye model, and much of this broadening is due to the distribution of network lengths.

description: Starting from equations of state of nucleonic and color-superconducting quark matter and assuming a first-order phase transition between these, we construct an equation of state of stellar matter, which contains three phases: a nucleonic phase, as well as two-flavor and three-flavor color-superconducting phases of quarks. Static sequences of the corresponding hybrid stars include massive members with masses of $\sim 2 M_{\odot}$ and radii in the range of $13< R < 16$ km. We investigate the integral parameters of rapidly rotating stars and obtain evolutionary sequences that correspond to constant rest-mass stars spinning down by electromagnetic and gravitational radiation. Physically new transitional sequences are revealed that are distinguished by a phase transition from nucleonic to color-superconducting matter for some configurations that are located between the static and Keplerian limits. The snapshots of internal structure of the star, displaying the growth or shrinkage of superconducting volume as the star's spin changes, are displayed for constant rest mass stars. We further obtain evolutionary sequences of rotating supramassive compact stars and construct pre-collapse models that can be used as initial data to simulate a collapse of color-superconducting hybrid stars to a black hole.

An investigation and development of a novel quality control system based on contactless resistivity measurement

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Industrial and product design

description: Measuring the diameter of a metal product during manufacturing is an important Quality Control activity in many industries including manufacturing of wires, nails, metal tubes and many more. Using manual measuring techniques in such situations is impractical because it is slow and time consuming. Many attempts have been made to automate the monitoring of the diameter of manufactured wires without disruption to the manufacturing process but these systems are either complicated to set-up or very expensive. This thesis investigates the feasibility of measuring the diameter of a conductive material with circular cross section area (e.g., wires, rods, nails, etc) without making any physical contact with the material itself. Such a measuring system could be extremely useful as a Quality Control mechanism for monitoring the fluctuations in the diameter of manufactured wires, rods or nails without disrupting the manufacturing process. The experimental activity has involved the design, construction and testing of a prototype system to measure the diameter of different metals, both solid bars and hollow tubes, without making physical contact with the samples. The theory of operation of the proposed system is based on the well-developed Contactless Resistivity Measurement theory used in Solid State Physics where the main interest is to measure the resistivity of the material knowing its dimension. In this project, we are trying to investigate the feasibility of using the same principle to measure the dimension of the sample knowing its resistivity. Results presented in this project proved the possibility of measuring the diameter of a conductive material without making physical contact with it. Further research will include: Increase the accuracy and reliability of the system; consider the effect of a moving wire on the accuracy and reliability of the measurement; developed a real-time industrial system. Further research will include measuring the thickness of thin metal coats where the physical measurement of thickness is extremely difficult and complicated.
The dissipative phase transition in a pair of coupled noisy two-level systems

description: We study the renormalization group (RG) equations of a pair of spin-boson systems coupled in the z-direction with each other. Each spin is coupled to a different bath of harmonic oscillators. We introduce a systematic adiabatic RG, which generalizes the first-order adiabatic renormalization previously used for the single spin-boson model, and we obtain the flow equations for the tunneling constant, the dissipation strength and the inter-spin coupling up to third order in the tunneling. If one of the two spins is treated as a constant magnetization the other spin is described by a biased spin-boson Hamiltonian. In this case the RG equations we find coincide with the ones obtained via a mapping to a long-range Ising chain. If the whole Ohmic two-spin system is considered the Kosterlitz-Thouless phase transition is replaced by a second-order phase transition. In the case of a sub-Ohmic bath our approach predicts that the two-spin system is always localized.

Carbon electrode for the oxygen reduction reaction
Creators: name: Feng, Jingyu
Publisher: name: Imperial College London
Year: 2021

description: This PhD thesis presents work on developing freestanding carbon electrodes for the oxygen reduction reaction application cost-effectively and sustainably. Within different alternatives to the high-cost Pt catalysts, heteroatoms and transitional metals modified carbon electrocatalysts have shown great promise to reduce the use of Pt. Meanwhile, synthesising freestanding catalysts has drawn interest due to the advantages of being binder-free, fewer manufacturing steps, and high recyclability. The first part of this thesis focuses on synthesising a freestanding carbon electrode with a hierarchical porosity and abundant nitrogen-doped sites. The carbon electrodes were synthesised through hydrothermal carbonization, followed by a pelleting process and further carbonization. Uniformly dispersed nitrogen sites and high specific surface area were obtained for the carbon electrodes. The electrochemical activity showed high stability in the freestanding configuration, and I found only the surface of electrode was reducing oxygen. The second part focuses on improving the carbon electrode's catalytic performance via post functionalization of the as-obtained nitrogen-doped carbon electrodes. Functionalization was carried out by immersing the carbon electrode into Fe solutions and followed by carbonization. The Fe was found to exist mainly as single sites. The electrochemical performance showed doubled current density compared to without Fe, and 100,000 s (27.77 h) stability was observed at 0.5 V. Through ex-situ X-ray absorption spectroscopy and electron paramagnetic resonance studies, Fe sites were found responsible for reducing oxygen. The third part focuses on the scalable synthesis of a low-cost iron, nitrogen co-doped carbon. Powdered iron, nitrogen co-doped carbon catalysts was prepared by hydrothermal carbonization and high-temperature post carbonization. FeN4 was found to be the main iron existing form in the obtained catalysts. Two different precursors containing Fe2+ and Fe3+ are compared. Both chemical and structural differences have been observed in catalysts starting from Fe2+ and Fe3+ precursors. Furthermore, this catalyst is studied in an anion exchange membrane fuel cell.

description: We propose a technique for engineering momentum-dependent dissipation in Bose-Einstein condensates with non-local interactions. The scheme relies on the use of momentum-dependent dark-states in close analogy to velocity-selective coherent population trapping. During the short-time dissipative dynamics, the system is driven into a particular finite-momentum phonon mode, which in real space corresponds to an ordered structure with non-local density-density correlations. Dissipation-induced ordering can be observed and studied in present-day experiments using cold atoms with dipole-dipole or off-resonant Rydberg interactions. Due to its dissipative nature, the ordering does not require artificial breaking of translational symmetry by an opticallattice or harmonic trap. This opens up a perspective of direct cooling of quantum gases into strongly-interacting phases.

description: Evolution by the Gross-Pitaevskii equation, which describes Bose-Einstein condensates under certain conditions, solves the unstructured search problem more efficiently than does the Schrödinger equation, because it includes a cubic nonlinearity, proportional to $|ψ|^2ψ$. This is not the only nonlinearity of the form $f(|ψ|^2)ψ$ that arises in effective equations for the evolution of real quantum physical systems, however: The cubic-quintic nonlinear Schrödinger equation describes light propagation in nonlinear Kerr media with defocusing corrections, and the logarithmic nonlinear Schrödinger equation describes Bose liquids under certain conditions. Analysis of computation with such systems yields some surprising results; for example, when time-measurement precision is included in the resource accounting, searching a "database" when there is a single correct answer may be easier than searching when there are multiple correct answers. In each of these cases the nonlinear equation is an effective approximation to a multi-particle Schrödinger equation, for search by which Grover's algorithm is optimal. Thus our results lead to quantum information-theoretic bounds on the physical resources required for these effective nonlinear theories to hold, asymptotically.

description: Agricultural landscapes often provide an impoverished environment for bees given their limited plant and pollen diversity. Agri-environment schemes (AES) such as flower strips have been developed to improve the quality of the agricultural environment for bees but their  efficacy  varies with their composition and, for specific pollinators, with the value of the available plant species. This study provides a detailed report of the pollen collection patterns of two bee species, the western honey bee (Apis mellifera L.) and the common eastern bumble bee (Bombus impatiens Cresson), over their foraging season. We compared the floral constancy, pollen richness and diversity of the two bee species and the pollen morphotypes of bee-collected pollen   in relation to resource availability. The honey bee was more flower constant while the bumble bee collected a greater family level diversity of pollen. While both bee species collected similar resources over their entire foraging season, the preferred morphotypes in given surveys differed between bee species. Neither bee species collected resources based on their availability but indicated patterns of preference and avoidance. We discuss how such knowledge can inform on the composition of AES to best sustain these pollinators in more impoverished depauperate agricultural landscapes.

description: This dataset was collected as part of a field experiment in 2016. Corbicular pollen loads of honey bees and bumble bees were collected, along with floral resource availabilty from June through September. The contents of pollen loads were idenfied using visual microscopy to determine the frequency of flower constancy, along with the richness and diversity of pollen collected by bee colonies. In addition, the abundance distribution of flower resources was compared to that of bee collected pollen to examine more preferred and less preferred pollen types for these two bee species throughout the foraging season. Floral abundance was sampled seperately for wildflowers, alfalfa, corn, and soybean, so there will be a seperate dataset for each.

Wet spinning fibres from imogolite and carbon nanotubes
Creators: name: Moore, Joseph
Publisher: name: Imperial College London
Year: 2022

description: As 1D materials with high intrinsic strength and stiffness, nanotubes are promising building blocks for the next generation of fibres in structural composites. This thesis explores wet spinning techniques for assembling macroscale fibres from nanotubes. Carbon nanotubes (CNTs) are an obvious target material to compete with commercial carbon fibres, based on their excellent intrinsic mechanical properties and low density, alongside high electrical conductivity for multifunctional applications. However, studying CNT materials is challenging due to their intrinsically high optical absorbance and low X-ray scattering cross-section, as well as the dispersity of typical feedstocks in both size and helicity. Imogolite nanotubes (INTs) are an inorganic analogue that offers an opportunity to observe the assembly of nanotubes into fibres using both polarised optical microscopy (POM) and X-ray scattering (XRS). In contrast to CNTs, INTs are optically transparent and can be synthesised at low temperature to provide feedstocks that are uniform in structure and diameter. In this work, the first known pure INT fibres have been produced and used to understand the nanotube wet spinning process. In situ POM demonstrated that in cylindrical spinnerets the spinning dope undergoes plug flow with inhomogeneous alignment due to the shear thinning nature of the solutions. The use of a tapered spinneret enables good alignment of the spinning dope, due to the induced extensional flow. Using this information, CNT fibres were spun from reduced CNT solutions and the wet spinning process was refined using a combination of in situ observation and statistical experimental design. The dissolution of negatively-charged CNTs (nanotubides) was examined both from a theoretical perspective and experimentally to identify the key conditions required to obtain homogeneous spinning dopes. The optimal dissolution depended upon both degree of charging and effective stirring. The optimised CNT dope was then wet spun using a variety of coagulating systems to identify the accessible process window and optimum parameters for spinning from these reactive charged solutions. Further improvement of the CNT fibre properties is predicted to arise through the use of higher aspect ratio CNT feedstocks. However, challenges still remain in the liquid phase processing of longer CNTs. In order to create CNT fibres competitive with commercial CFs, future research should focus on how to process these longer feedstocks following the guidance in this thesis.

description: A key component to the structuring effects of neoliberalism is its impact on the subjectivity of citizens (Brown, 2003). Individuals are increasingly induced to act as self-disciplining, self-transforming entrepreneurial citizens, fully responsible for their own successes and failures (Harvey, 2005). Viewed in tandem with the changing landscape of employment under post-Fordism, women have come to be positioned as ideal neoliberal citizens and workers (Adkins, 1999, Gill and Scharff, 2011, Harris, 2006, Morini, 2010). Women possess a cultural legacy of self- transformation and self-discipline, and their ‘natural’ feminine characteristics align with expectations of contemporary affective and emotional labour. Within this context, a narrative abounds that women can make-over work, to better suit their passions and interests. Etsy.com is the largest digital craft-selling platform worldwide and promises its largely female workforce a means towards pleasurable, self-actualising business ownership. Through an analysis of twenty-one semi-structured interviews, this thesis explores the lived realities of women’s experiences of such freelance employment, via the Etsy.com platform. I will argue that women engaged in Etsy-based work must reconcile a complex web of competing cultural, economic, and social demands, which centre on contradictory notions of ideal femininity. Moreover, Etsy.com itself operates as a structuring force, that iterates contradictory gendered ideals of ‘successful’ femininity. How such contradictions are navigated is dependent not only on individual women’s entrepreneurial capacities but access to, and capacity to utilise, wider forms of capital.
Stability of Bianchi attractors in Gauged Supergravity

description: In this paper, we analyse the stability of extremal black brane horizons with homogeneous symmetry in the spatial directions in five dimensional gauged supergravity, under the fluctuations of the scalar fields about their attractor values. We examine the scalar fluctuation equations at the linearised level and demand that the fluctuations vanish as one approaches the horizon. Imposing certain restrictions on the Killing vectors used for gauging we find that the necessary conditions for stability are satisfied only by a subclass of the Bianchi metrics whose symmetry group factorises into a two dimensional Lifshitz symmetry and any homogeneous symmetry group given by the Bianchi classification. We apply these results to a simple example of a gauged supergravity model with one vector multiplet to find the stable attractors.

description: In this paper, we consider high scale (100 TeV) supersymmetry (SUSY) breaking and realize the idea of hilltop supernatural inflation in concrete particle physics models based on flipped-SU(5) and Pati-Salam models in the framework of supersymmetric grand unified theories (SUSY GUTs). The inflaton can be a flat direction including right-handed sneutrino and the waterfall field is a GUT Higgs. The spectral index is $n_s=0.96$ which fits very well with recent data by PLANCK satellite. There is no both thermal and non-thermal gravitino problems. Non-thermal leptogenesis can be resulted from the decay of right-handed sneutrino which plays (part of) the role of inflaton.

The Effect of Manuka Honey on the Cell Cycle of MRSA
Creators: name: Jenkins, Rowena
Publisher: name: Cardiff Metropolitan University

Subjects: Bacteriology

description: Preliminary studies have shown that manuka honey affects the cell cycle of MRSA by impeding cell division, but mode of action was unknown. Cell division depends on the formation of septa and cleavage of peptidoglycan at cytokinesis. This study investigated how manuka honey might alter the cell cycle of EMRSA-15. Physiological and chemical changes in the bacteria exposed to manuka honey were determined using time to kill studies, confocal and electron microscopy. Data indicated that honey had a bactericidal effect on MRSA, inhibiting the cell cycle cytokinesis. Increased septum formation was noted in honey treated cells by transmission electron microscopy. Cell division components including FtsZ and Endo-B-N-Acetylglucosaminidase were investigated using cell wall turbidity assays, zymography, immunofluorescence and immuno gold labelling. Manuka honey treated MRSA cells showed a marked reduction in hydrolase activity after 12 hours compared to untreated cells. The immunofluorescence indicated an initial increase in FtsZ production followed by a significant decrease by 24 hours. PCR of FtsZ showed a 10% increase in production after 1 and 4 hours. Localization by gold labelling gave inconclusive results. Immunofluorescence of Endo-B-N-Acetylglucosaminidase showed a decrease in the amount of enzyme over 24 hours and localization by gold labelling indicated altered distribution of this enzyme. PCR showed no significant difference in expression. 2-D electrophoresis showed a differing proteomic profile between control cells and those treated with honey, with a potential target protein being identified. Methylglyoxal (an antibacterial component of manuka honey) was investigated after a report named this as potentially the active component of manuka honey. Results showed it has an effect but is not wholly responsible for the effects induced by manuka honey. It was concluded that increased numbers of cells with septa were formed and alteration in production of proteins and enzymes resulted in MRSA cells exposed to bactericidal concentrations of manuka honey. The work was also carried out with artificial honey controls, indicating that effects seen were not due to sugar content within honey or methylglyoxal content.

title: Phenotypic variation and sexual dimorphism of the Madeiran wall lizard (Tiera dugesii)
Creators: name: Thomas, J
Publisher: name: Liverpool John Moores University
Year: 2023

description: The Madeiran wall lizard, Teira dugesii (Milne-Edwards, 1829) is an endemic lizard of the Madeiran archipelago and is widely dispersed throughout different environments. The previous reports of morphological variation of T.dugesii within Madeira have not provided clear patterns but prompted this research into sexual and environment-related differences in morphology. For this study, geometric morphometrics (GMM) techniques combined with phenotypic trajectory analysis were applied to investigate the dorsal and lateral head shape morphology of T. dugesii. Univariate and multivariate statistical analyses were conducted to assess sexual dimorphism within the species and identify if ecological adaptations towards intertidal and terrestrial habitats occurred in the T. dugesii populations across four different localities within Madeira. Sexual dimorphism accounted for the largest proportion of size and shape variation in head morphology. Males exhibited a larger and more robust head shape compared to that of females which displayed relatively more petite and slender head shapes. Intertidal/terrestrial habitats were associated with head shape variation between sexes. Specimens from terrestrial environments also consistently had larger heads compared to intertidal specimens from the same locality. Additionally, phenotypic trajectory analysis revealed habitat differences in head morphology, again supporting parallel phenotypic divergence across localities between lizards from terrestrial and intertidal habitats.

description: Admissible point transformations between Burgers equations with linear damping and time-dependent coefficients are described and used in order to exhaustively classify Lie symmetries of these equations. Optimal systems of one- and two-dimensional subalgebras of the Lie invariance algebras obtained are constructed. The corresponding Lie reductions to ODEs and to algebraic equations are carried out. Exact solutions to particular equations are found. Some generalized Burgers equations are linearized to the heat equation by composing equivalence transformations with the Hopf-Cole transformation.
