The Engineering and Development of pH-Responsive Biopolymers for Drug Delivery Applications

description: This dissertation describes experimental studies to understand the structure of biocompatible pH responsive polymers and their interaction with the biological system in order to design more effective entities for biomedical applications. A systemic approach was used to study the structure and biological interaction of pH responsive biocompatible poly (L-lysine iso-phthalamide) (PLP) polymer and its derivatives. Poly (L-lysine isophalamide) is a unique polymer that contains pendant carboxylate group and modification with phenylalanine was able to enhance the intracellular delivery efficiency of the polymer. However, the exact structure and mechanism of action remains mostly unknown. In this study, a variety of modifiers was used to synthesise new PLP derivatives in order to elucidate their effect on the polymer structure and other functional characteristics. New characterisation methods including circular dichroism and small angle neutron scattering were introduced to provide more detailed information on the polymer structure and evidence to explain the polymer-membrane interaction. It was determined that PLP adopted a helical structure in solution and that the ability of the PLP- derivative to from a lamellar structure in solution would lead to enhanced intracellular delivery effectiveness. Chirality of the PLP components and modifiers were also examined. Three PLP enantiomers and four phenylalanine modified PLP were synthesised and characterised. The polymers were determined to be chemically identical and had comparable functionalities. However, it was proven again that the ability for polymer to form lamellar structure would result in enhanced intracellular delivery efficiency. The structural and functional information was later used to better design a drug delivery system for the cryopreservation of mammalian cells. The approach was successful, as the resulting vitamin E modified polymer was able to achieve similar cryosurvival rate with trehalose as cryoprotectant compared the gold standard DMSO protocol. The success marked the importance of application-specific design and understanding of drug delivery systems.

description: In the spirit of Kobayashi's applications of methods of invariant metrics to questions of projective geometry, we introduce a projective analogue of the complex squeezing function. Using Frankel's work, we prove that for convex domains it stays uniformly bounded from below. In the case of strongly convex domains, we show that it tends to 1 at the boundary. This is applied to get a new proof of a projective analogue of the Wong-Rosay theorem.

title: Gendered spaces in contemporary Irish poetry
Creators: name: Fulford, Sarah
Publisher: name: University of Kent
Year: 2022

description: The thrust of this thesis is summarized by the following questions: How does contemporary Irish poetry migrate from traditional conceptions of identity drawn on by the cultural nationalism of the Irish Literary Revival, and what effects does this have on understanding gendered and national identity formation? Chapters are on the following: Seamus Heaney, Tom Paulin, Paul Muldoon, MedbhMcGuckian, Eavan Boland and Sara Berkeley. These poets are chosen for discussion since their work most effectively engages with the relationship between woman and nation, the representation of gendered national identity, and the importance of feminist and post-colonial theorization. Focusing on poetry worth and South of the border from the last fifteen years, the thesis asks how a younger generation of poets provide a response to nationality which is significantly different from their predecessors. The thesis is composed of three parts: the first understand how the male poets depart from conventional conceptions of the nation with reference to post-colonial theorization; the second explores how feminist theorization informs readings of how the female poets respond to the nation; the final part investigates migration in the poetry and problematizes this in terms of post-nationalism. Discussing the issue of deterritorialization in Irish poetry, the thesis notice how as the poets attempt to take flight from the mythologies of nationhood, they undermine the monoliths of gendered and national identity inscribed within Irish political discourse, which is typified at a representative level by the figure of Mother Ireland or Cathleen Ni Houlihan. Investigating the ways in which gender and nation, and the body and space are reinscribed by the poets, the thesis argues that their poetry challenges authentic conceptions of Irish identity and the nation-state, so as to loosen the legacy of a colonial and nationalist inheritance.

description: This research uses data from the 2005–2011 Agricultural Resource Management Survey and a two-part-model regression procedure to examine the impact of health insurance and other relevant socio-economic factors on the distribution of health care expenditures among U.S. farm households. Find-ings show the importance of privately acquired health insurance coverage in explaining inequality in health care expenditures. The results also reveal, among other things, a statistical positive association between health care expenditures and farm operators who fall into the baby boomer age category. A similar statistical association is found for higher income levels but not for inequality of income.

description: The formal solution of a general stargenvalue equation is presented, its properties studied and a geometrical interpretation given in terms of star-hypersurfaces in quantum phase space. Our approach deals with discrete and continuous spectra in a unified fashion and includes a systematic treatment of non-diagonal stargenfunctions. The formalism is used to obtain a complete formal solution of Wigner quantum mechanics in the Heisenberg picture and to write a general formula for the stargenfunctions of Hamiltonians quadratic in the phase space variables in arbitrary dimension. A variety of systems is then used to illustrate the former results.

description: In Finland, expanding dairy farms often face the problem of additional fields being geographically distant and only available as small parcels. We develop a stochastic production frontier model to estimate the technical efficiency of Finnish dairy farms and simulate the effect of parcel distance and parcel size on the efficiency of an average farm for 2000 through 2009. The overall development of technical efficiency is positive during the study period but increases in distance and decreases in parcel size both significantly reduce farm efficiency. Therefore, efforts to improve the parcel structure are justified.

description: Spiral drawings on paper are used as routine measures in hospitals to assess Parkinson’s Disease motor deficiencies. In the age of emerging mobile health tools and Artificial Intelligence a comprehensive digital setup enables granular biomarker analyses and improved differential diagnoses in movement disorders. This study aims to evaluate on discriminatory features among Parkison’s Disease patients, healthy subjects and diverse movement disorders. Overall, 24 Parkinson’s Disease patients, 27 healthy controls and 26 patients with similar differential diagnoses were assessed with a novel tablet-based system. It utilizes an integrative assessment by combining a structured symptoms questionnaire—the Parkinson’s Disease Non-Motor Scale—and 2-handed spiral drawing captured on a tablet device. Three different classification tasks were evaluated: Parkinson’s Disease patients versus healthy control group (Task 1), all Movement disorders versus healthy control group (Task 2) and Parkinson’s Disease patients versus diverse other movement disorder patients (Task 3). To systematically study feature importances of digital biomarkers a Machine Learning classifier is cross-validated and interpreted with SHapley Additive exPlanations (SHAP) values. The number of non-motor symptoms differed significantly for Tasks 1 and 2 but not for Task 3. The proposed drawing features partially differed significantly for all three tasks. The diagnostic accuracy was on average 94.0% in Task 1, 89.4% in Task 2, and 72% in Task 3. While the accuracy in Task 3 only using the symptom questionnaire was close to the baseline, it greatly improved when including the tablet-based features from 60 to 72%. The accuracies for all three tasks were significantly improved by integrating the two modalities. These results show that tablet-based drawing features can not only be captured by consumer grade devices, but also capture specific features to Parkinson’s Disease that significantly improve the diagnostic accuracy compared to the symptom questionnaire. Therefore, the proposed system provides an objective type of disease characterization of movement disorders, which could be utilized for home-based assessments as well.

description: We apply a flexible parametric model, a combination of generalized Plummer profiles, to infer the shapes of the stellar density profiles of the Milky Way's satellite dwarf spheroidal galaxies (dSphs). We apply this model to 40 dSphs using star counts from the Sloan Digital Sky Survey, PanStarrs-1 Survey, Dark Energy Survey, and Dark Energy Camera Legacy Survey. Using mock data, we examine systematic errors associated with modelling assumptions and identify conditions under which our model can identify `non-standard' stellar density profiles that have central cusps and/or steepened outer slopes. Applying our model to real dwarf spheroidals, we do not find evidence for centrally cusped density profiles among the fifteen Milky Way satellites for which our tests with mock data indicate there would be sufficient detectability. We do detect steepened (with respect to a standard Plummer model) outer profiles in several dSphs--Fornax, Leo I, Leo II, and Reticulum II--which may point to distinct evolutionary pathways for these objects. However, the outer slope of the stellar density profile does not yet obviously correlate with other observed galaxy properties.

description: We report a Chandra observation of the z=3.395 radio galaxy B2 0902+343. The unresolved X-ray source is centred on the active nucleus. The spectrum is well fit by a flat power law of photon index of Gamma~1.1 with intrinsic absorption of 8x10^{22} cm^{-2}, and an intrinsic 2-10keV luminosity of 3.3x10^{45} erg/s. More complex models which allow for a steeper spectral index cause the column density and intrinsic luminosity to increase. The data limit any thermal luminosity of the hot magnetized medium, assumed responsible for high Faraday rotation measures seen in the radio source, to less than ~10^{45} erg/s.

description: We present the conceptual design of an alternative injector system based on laser-plasma accelerator technology, to deliver high-quality electron bunches to PETRAIV - the future 4th generation synchrotron light source at DESY. The design consists ofa laser-plasma accelerator to produce electron bunches at 6 GeV with state-of-the-artenergy spread and stability, and a X-band energy compressor beamline to further reducethe overall beam energy deviations and maximize the charge injection throughput intothe PETRA IV storage ring. Driven by the Petawatt upgrade of DESY’s new flagship laserKALDERA, the plasma injector system can be used to top up the PETRA IV storage ring,significantly lowering the load on the conventional injector chain. Ultimately, uponfurther development of high-efficiency, high-power laser drivers that operate at highrepetition rates, the plasma injector could potentially replace the conventional systemin the future and dramatically reduce the spatial footprint and energetic cost of thewhole injector complex.

description: We study the anomalous triple gauge boson couplings (aTGC) in $ZW^\pm$ production in $3l$ + missing $E_T$ channel at the LHC for $\sqrt{s}=13$ TeV. We use cross sections, azimuthal asymmetry, forward-backward asymmetry, and polarization asymmetries of $Z$ and reconstructed $W$ to estimate simultaneous limits on the anomalous couplings for both the effective vertex formalism as well as the effective operator approach using the Markov-chain--Monte-Carlo (MCMC) method for luminosities $35.9$ fb$^{-1}$, $100$ fb$^{-1}$, $300$ fb$^{-1}$, $1000$ fb$^{-1}$, and $3000$ fb$^{-1}$. The trilepton invariant mass ($m_{3l}$)and the transverse momentum of $Z$ ($p_T(Z)$) are found to be sensitive to the aTGC for the cross sections as well as for the asymmetries. We observed that the asymmetries significantly improve the measurement of anomalous couplings at the high-luminosity large hadron collider (LHC) if a deviation from the Standard Model (SM) is observed.

description: The 1996 Safe Drinking Water Act Amendments required that water utilities send quality reports to customers. We test whether receiving such reports of health violations increases purchases of bottled water using newly released data and disaggregate changes in demand at the intensive and extensive margins. We find that a water-quality violation makes American households 25 percent more likely to purchase bottled water and, among purchasers, expenditures increase 4–7 percent, both larger responses than found in previous studies. Consumers spend approximately $300 million per year—about 4 percent of annual national spending on bottled water—to avoid health risks associated with violations.

description: We report the discovery and monitoring of radio emission from the Type Ic SN 2002ap ranging in frequency from 1.43 to 22.5 GHz, and in time from 4 to 50 days after the SN explosion. As in most other radio SNe, the radio spectrum of SN 2002ap shows evidence for absorption at low frequencies, usually attributed to synchrotron self-absorption or free-free absorption. While it is difficult to discriminate between these two processes based on a goodness-of-fit, the unabsorbed emission in the free-free model requires an unreasonably large ejecta energy. Therefore, on physical grounds we favor the synchrotron self-absorption (SSA) model. In the SSA framework, at about day 2, the shock speed is approximately 0.3c, the energy in relativistic electrons and magnetic fields is approximately 1.5e45 erg and the inferred progenitor mass loss rate is approximately 5e-7 solar masses per year (assuming a 1,000 km/sec wind). These properties are consistent with a model in which the outer, high velocity supernova ejecta interact with the progenitor wind. The amount of relativistic ejecta in this model is small, so that the presence of broad lines in the spectrum of a Type Ib/c supernova, as observed in SN 2002ap, is not a reliable indicator of a connection to relativistic ejecta and hence gamma-ray emission.

description: A sample selection system is used to examine factors associated with likelihoods of purchase and amounts spent on fresh, frozen, and processed meats in Malaysia based on data from the 2009/10 Malaysian Household Expenditure Survey. Statistical tests support use of the sample selection system estimator over more conventional estimation procedures. Results indicate that household size, location of residence, ethnicity, age, education, and income are closely associated with patterns of house-hold expenditures for fresh, frozen, and processed meats. Several observations are noted regarding determinants of purchase likelihoods and expenditure patterns for meat in Malaysia.

description: The study examines the trend, annual and seasonal variability and relative profitability of spices in Bangladesh. All spices except turmeric and ginger show negative growth rates in production since independence. Production growth trend of all spices was lower compared with other food crops but it was reverse in case of nominal price trend. Real price remained more or less same during the study period. Production as well as price fluctuation were higher for onion and garlic and lower for ginger and turmeric. Price fluctuation is directly related to the production fluctuation. Seasonality mostly depends on the perishability of the product and seasonal price variation of spices decreased in the recent years. All the selected spices except coriander are more profitable compared with their competing crops except potato and lentil. On average, 82% of production, were sold during harvesting period.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The issue of the international buffer stock scheme for the stabilization of prices of primary commodities came to forefront in the mid 1970's. This survey aims at highlighting some critical issues with a selective review of the major recent contributions in the area. The analytical work on commodity price stabilization started with the works of Waugh in 1944, Oi in 1961 and Massel in 1969. Johnson (1976) clarified some of the underlying assumptions and showed the impact on revenue under different supply and demand conditions. Among others, Behrman (1979) and Vines (1984) provided empirical and analytical support to the argument. One outstanding contribution in the area is that of Newbery and Stiglitz (1981) whose theoretical work and empirical estimates tend to reject the case for price stabilization. Kanbur (1984) shows that the analysis of Newbery and Stiglitz (1981) is largely microeconomic that ignores the potential macroeconomic benefit emphasized by Kaldor (1976, 1983).

description: New families of non-parity-time-symmetric complex potentials with all-real spectra are derived by the supersymmetry method and the pseudo-Hermiticity method. With the supersymmetry method, we find families of non-parity-time-symmetric complex partner potentials which share the same spectrum as base potentials with known real spectra, such as the (complex) Wadati potentials. Different from previous supersymmetry derivations of potentials with real spectra, our derivation does not utilize discrete eigenmodes of base potentials. As a result, our partner potentials feature explicit analytical expressions which contain free functions. With the pseudo-Hermiticity method, we derive a new class of non-parity-time-symmetric complex potentials with free functions and constants, whose eigenvalues appear as conjugate pairs. This eigenvalue symmetry forces the spectrum to be all-real for a wide range of choices of these functions and constants in the potential. Tuning these free functions and constants, phase transition can also be induced, where conjugate pairs of complex eigenvalues emerge in the spectrum.

The study is also intended to forecast the yield of the Aman crop and to determine the difference between the forecast and actual yield estimation by varieties at different stages of the crop of Rangpur district in Bangladesh. On the basis of forecast estimate pertinent authority could take appropriate actions such that the sufferings of the rural people are minimized. Data were collected from district meteorological offices and district fertilizer sales office of Rangpur district. Data were collected from 1968 to 1988 in the weekly form Forecasting equations were formulated where predictor variables showed significant effect at different stages (i.e. vegetative reproductive, grain filling and maturation stages) for Aman rice crop on weekly basis. Simple and multiple linear regression analysis were used for analytical purposes. F-test, T-test and test of lack of fit were used to test the validity of the models. Statistical analysis which showed retrodictive results (20 years average) very close to actual estimate of Rangpur district were IIYV Aman at Vegetative and at reproductive stages whereas for LV Aman at Vegetative, reproductive, grain filling and maturation stage. Recommendations were made for inclusion of more non weather variables and to use the models for other districts for forecasting.

description: This thesis explores how Virgil's readers imagined the authorial techniques and biographical persona of Virgil, the most canonical – yet extraordinarily elusive – Latin poet. While ancient biography is often dismissed as transparently fictional, this thesis makes a case for taking biographical reports of Virgil’s authorial techniques seriously – if not as historical fact, then as sites where later readers creatively explored conceptions of authorship, negotiated literary practices, and constructed an author worthy of reading. These shifting portrayals of 'the poet at work' interact with interpretations of his works in complex and sophisticated ways. By re- evaluating them as fragmented traces of interpretation and creative engagement, we can not only reassess the reception of Virgil, but radically alter our understanding of ancient literary criticism too. After an introduction outlining the theoretical and methodological premises of this study, the thesis falls into two halves. The first two chapters explore biographical accounts of Virgil’s authorship which purport to be factual, focusing especially on scholarly texts such as commentaries, biographies, histories and miscellanies. Chapter 1 tackles anecdotes of Virgil’s methods of composition and revision, tracing the uses later authors made of them and examining how they interact with Virgil’s texts; I argue that they reflect a keenly observant reading of Virgil’s own metapoetic modes of authorial self-fashioning. The second chapter shifts from the written to the oral, investigating reports of the performance and recitation of Virgil’s works, particularly by the poet himself. The third, fourth and fifth chapters, by contrast, investigate explicitly fictional representations of Virgil: those in which he is openly represented as a character from his own works, by means of biographical allegory. This section focuses principally on poetic texts (Propertius, Calpurnius Siculus), and explores the pendulum-swing of attribution, as these poets attribute the allegorising move now to Virgil, now to their own creativity.

Isospin model for suppression of charge order in hole- doped NaV_2O_5

description: The layered perovskite compound NaV_2O_5 exhibits charge ordering (CO) and spin gap formation which is driven by inter- site Coulomb forces and exchange dimerisation. Experimentally it was found that the CO transition is rapidly reduced by doping. Charge ordering in NaV_2O_5 has a quasi 1D character due to inter- ladder frustration in the Trellis lattice. Based on an extended pseudospin (T=1) approach for hole doped NaV_2O_5 ladders we construct an Ising like model that explains qualitatively the destruction of the CO phase as function of hole doping δand show how the CO parameter depends on δand the ratio of Coulomb and hopping energies.

description: This thesis investigates three areas of scientific interest under the umbrella of gravity- driven flow. In the first problem we analyse the effect of curved boundaries on the evolution of finite-release low-Reynolds-number exchange flow. From the equations of motion in an annular geometry we derive the governing nonlinear PDE for the evolution of the density interface. Systematically varying the initial conditions leads to the recognition that there are different routes to equilibrium. Asymptotic analysis of squeezing and draining limits allows us to find analytical solutions with good agreement to the numerical solutions. Finally, we show the time taken to reach equilibrium can vary by two orders of magnitude. We relate these time scales to the application of displacing drilling lubricant by cement in a horizontal oil well. In the second problem we develop a simplified theory relating the downstream structure of horizontally propagating turbulent gravity currents to uniform source conditions. We constrain the downstream solutions by conserving the flux of horizontal buoyancy and momentum. With an experimentally motivated ansatz that the down- stream horizontal velocity and buoyancy structure is either i) entirely linearly stratified ii) consists of a well-mixed uniform lower region overlain by a linearly stratified region, we can relate the upstream conditions to the downstream conditions as a function of source Froude number, downstream gradient Richardson number, and a shape factor φ. These solutions lead to global constraints on the entrainment flux and energy dissipation of transitioning currents. In the third problem we present a series of new numerical simulations on two- dimensional gravity currents propagating down a rigid inclined boundary. From the data generated by the simulations we can estimate the rate of entrainment E of these currents, and present this data over a range of angles θ. Furthermore, we show that around 10% of the buoyancy, and 15% of the momentum flux, is transported by turbulent fluctuations. We also show that the Richardson number Ri of these currents remains marginally stable Ri ≈ 0.25 and is independent of angle. Finally we show that the coefficient of drag cd experienced by these currents is constant and approximately cd ≈ 0.01.

description: Input use efficiency and productivity of different sizes of farms producing FIYV Boro in some selected areas of Brahman Baria district were investigated by employing primarily a Cobb-Douglas production function. Returns to scale and farmer's capability of producing at the least cost level were statistically tested. Farm size and productivity relationships were found to be positive. Boro production was characterized by increasing return to scale for only the medium farms. Few inputs were used in Boro production at the least cost combination level. Adequate extension services including application of right quantity of inputs at right times may help achieve efficiency in input use and improve profitability.

description: Relative performance of alternative farming systems was studied by applying residual income measures such as gross margin, net farm income and management income. The results showed that gross margin per Taka of variable cost varied sufficiently among enterprises within each farming system. Among the individual enterprises within the crop component, vegetabale and fruits gave highest gross margin per Taka of variable cost in all the systems of farming. Among the components of the whole farm business, fish component had the highest gross margin per Taka of variable cost in all the systems of farming. Net farm income was reasonably high for all the systems. Except for the Crop-Cattle-PouItryFish system, all the systems earned negative management income. However, return to operator's labour and management was positive for all the systems. In view of the fact that many of the farm fixed resources have lower opportunity costs, it may be plausible to assume that farmers might be content with whatever positive return they earn over their composite input "labour and management".

description: It was recently shown (quant-ph/9909074) that parasitic random interactions between the qubits in a quantum computer can induce quantum chaos and put into question the operability of a quantum computer. In this work I investigate whether already the interactions between the qubits introduced with the intention to operate the quantum computer may lead to quantum chaos. The analysis focuses on two well--known quantum algorithms, namely Grover's search algorithm and the quantum Fourier transform. I show that in both cases the same very unusual combination of signatures from chaotic and from integrable dynamics arises.

description: Beat note measurements between a mode-locked and a continuous-wave laser as well as between two mode-locked sources were used to demonstrate that the sub-threshold, cavity filtered, amplified spontaneous emission is not stationary even when a fast mode-locking mechanism, such as nonlinear polarization rotation, is used to generate short pulses. A relatively small gain modulation of a few percents created by high intensity pulses can produce a significant modulation of the amplified noise once synchronously accumulated over several cavity round-trips, even if the repetition rate is faster than the gain dynamics.
