description: Finite cut-off effects strongly influence the thermodynamics of lattice regularized QCD at high temperature in the standard Wilson formulation. We analyze the reduction of finite cut-off effects in formulations of the thermodynamics of $SU(N)$ gauge theories with three different $O(a^2)$ and $O(a^4)$ improved actions. We calculate the energy density and pressure on finite lattices in leading order weak coupling perturbation theory ($T\rightarrow \infty$) and perform Monte Carlo simulations with improved $SU(3)$ actions at non-zero $g^2$. Already on lattices with temporal extent $N_τ=4$ we find a strong reduction of finite cut-off effects in the high temperature limit, which persists also down to temperatures a few times the deconfinement transition temperature.

Road development in the Brazilian Amazon and its ecological implications
Creators: name: Ahmed, Sadia Evelyn
Publisher: name: Imperial College London
Year: 2013

description: Roads are a distinctive feature in any landscape, with many countries giving 1-2% of their land surface over to roads and roadsides (Forman 1998). However, the ecological effects of roads spread beyond the physical footprint of the network and may impact 15-20% of the land or more (Forman & Alexander 1998). The Brazilian Amazon contains approximately one third of the world’s remaining rainforest, covering an area of 4.1 million km2. The region is highly biodiverse with 10-20 percent of the planet’s known species, it is also one of the three most bioculturally diverse areas in the world (Loh & Harmon 2005), and it provides many valuable ecosystem services. However, the Brazilian Amazon is rapidly undergoing extensive development with widespread land-use conversion. Road development is often perceived as the initial stage of development, opening access to remote areas for colonisation, agriculture development, resource extraction, and linked with these; deforestation (Chomitz & Gray 1996, Laurance et al. 2001, Perz et al. 2007, Laurance et al. 2009, Caldas et al. 2010). As such roads are a key spatial determinant of land use conversion in the Amazon region, dictating the spatial pattern of deforestation and biodiversity loss (Fearnside 2005, Kirby et al. 2006, Perz et al. 2008). Given that roads are a key spatial determinant of land use conversion and that they have extensive impacts on rates and patterns of habitat loss, it is important that we know how much, how fast and where road networks are developing in this globally important ecosystem. In this thesis, I aim to construct models of road network development to help better understand and predict the impacts of economic development in the Brazilian Amazon.

description: A method for the extraction of an effective meson-meson potential from Green functions, which can be obtained from a lattice simulation, is presented. Simulations are carried out for compact QED and QCD in four dimensions using the quenched approximation and the hopping parameter expansion. In a further study, a heavy-light meson is considered employing a conjugate gradient algorithm for the light propagators. Due to the Pauli exclusion principle, the results for QED indicate the existence of a hard core, but for QCD there is strong attraction at small meson distances.

Flow field and mixing in stirred vessels with regular and fractal impellers
Creators: name: Basbug, Salur
Publisher: name: Imperial College London
Year: 2017

description: The goal of this thesis is to explore the potential benefits of fractal objects in dynamic mixing applications. To this end, the performance of an impeller with fractal blades was evaluated and compared to the one with regular, rectangular-shaped blades. Direct Numerical Simulations (DNS) were performed to compute the flow and passive scalar fields inside an unbaffled stirred vessel in the transitional flow regime. It was observed that at Re=1600 the mean power consumption decreases by ca. 8% when the regular blades are replaced by fractal ones. The physical explanation for this reduction was provided by comparing several characteristics of the flows generated by the two types of impellers, such as the pressure distribution on blade surfaces, the time-average recirculation pattern and the trailing vortex system in wake of the blades, the radial transport of angular momentum and the distribution of energy dissipation inside the tank. Furthermore, fluctuations were observed in the power consumption with a peak frequency at ca. three times the impeller rotational speed, for both impeller types. It was discovered that these fluctuations are associated with a periodic event in the wake of the blades, which involves alternating growth and decay of the upper and lower cores of the trailing vortex pair as well as up-and-down swinging motion of the radial jet. Moreover, the mixing time required to homogenize an injected passive scalar was evaluated for both impeller types, at Sc=1. It was observed that the fractal impeller can lead to a shorter mixing time by 10-12%. This result was explained by the differences in characteristics of flow and scalar fields generated by regular and fractal blades. A simple mathematical model was suggested which is able to approximate the decay rate of the passive scalar fluctuations integrated over the tank volume.

description: We investigate the formation of virialized halos due to the gravitational collapse of collisionless matter using high-resolution N-body simulations. A variety of formation scenarios are studied, ranging from hierarchical clustering to monolithic radial collapse. The goal of these experiments was to study departures from the universal density profiles recently found to arise in cosmological settings. However, we found that even for models which exhibit quite a different formation history, the density and velocity dispersion profiles of the virialized halos are strikingly similar. Power law density profiles do not result even in models with initial power law profiles and no initial substructure or non-radial motions. Such initial conditions give rise to a radial orbit instability which leads to curved velocity dispersion and density profiles. The shapes of the density profiles in all our models are well parameterized by the profiles of halos formed in a generic cosmological setting. Our results show that the universality of dark halo density profiles does not depend crucially on hierarchical merging as has been suggested recently in the literature. Rather it arises because apparently different collapse histories produces a near universal angular momentum distribution among the halo particles. We conclude that the density and velocity dispersion profiles of virialized halos in an expanding universe are robust outcomes of gravitational collapse, nearly independent of the initial conditions and the formation history.

description: The chemical and magnetic structures of the series of compounds Ca$_{2-x}$La$_x$RuO$_4$ [$x = 0$, $0.05(1)$, $0.07(1)$, $0.12(1)$] have been investigated using neutron diffraction and resonant elastic x-ray scattering. Upon La doping, the low temperature S-Pbca space group of the parent compound is retained in all insulating samples [$x\leq0.07(1)$], but with significant changes to the atomic positions within the unit cell. These changes can be characterised in terms of the local RuO$_6$ octahedral coordination: with increasing doping the structure, crudely speaking, evolves from an orthorhombic unit cell with compressed octahedra to a quasi-tetragonal unit cell with elongated ones. The magnetic structure on the other hand, is found to be robust, with the basic $k=(0,0,0)$, $b$-axis antiferromagnetic order of the parent compound preserved below the critical La doping concentration of $x\approx0.11$. The only effects of La doping on the magnetic structure are to suppress the A-centred mode, favouring the B mode instead, and to reduce the Néel temperature somewhat. Our results are discussed with reference to previous experimental reports on the effects of cation substitution on the $d^4$ Mott insulator Ca$_2$RuO$_4$, as well as with regard to theoretical studies on the evolution of its electronic and magnetic structure. In particular, our results rule out the presence of a proposed ferromagnetic phase, and suggest that the structural effects associated with La substitution play an important role in the physics of the system.

Results obtained up to now with 200 configurations at $β=6.1$ on a $24^3\times64$ lattice and with 100 configurations at $β=6.3$ on a $32^3 \times80$ lattice suggest that the pseudoscalar decay constant varies little over this range of $β$ in both charm and bottom regions. Results for the $B$ parameter are also reported.

description: We use the two-point correlation function to calculate the clustering properties of the recently completed SSRS2 survey. The redshift space correlation function for the magnitude-limited SSRS2 is given by xi(s)=(s/5.85 h-1 Mpc)^{-1.60} for separations between 2 < s < 11 h-1 Mpc, while our best estimate for the real space correlation function is xi(r) = (r/5.36 h-1 Mpc)^{-1.86}. Both are comparable to previous measurements using surveys of optical galaxies over much larger and independent volumes. By comparing the correlation function calculated in redshift and real space we find that the redshift distortion on intermediate scales is small. This result implies that the observed redshift-space distribution of galaxies is close to that in real space, and that beta = Omega^{0.6}/b < 1, where Omega is the cosmological density parameter and b is the linear biasing factor for optical galaxies. We also use the SSRS2 to study the dependence of xi on the internal properties of galaxies. We confirm earlier results that luminous galaxies (L>L*) are more clustered than sub-L* galaxies and that the luminosity segregation is scale-independent. We find that early types are more clustered than late types, but that in the absence of rich clusters, the relative bias between early and late types in real space, is not as strong as previously estimated. Furthermore, both morphologies present a luminosity-dependent bias, with the early types showing a slightly stronger dependence on luminosity. We also find that red galaxies are significantly more clustered than blue ones, with a mean relative bias stronger than that seen for morphology. Finally, we find that the relative bias between optical and iras galaxies in real space is b_o/b_I $\sim$ 1.4.

Investigating the optimality of ancilla-assisted linear optical Bell measurements

description: In the last decade Grice and Ewert and van Loock found linear optical networks achieving near-unit efficiency unambiguous Bell state discrimination, when fed with increasingly complex ancillary states. However, except for the vacuum ancilla case, the optimality of these schemes is unknown. Here, the optimality of these networks is investigated through analytical and numerical means. We show an analytical upper bound to the success probability for interferometers that preserve the polarization of the input photons, saturated by both Grice's and Evert-van Loock's strategies. Furthermore, such an upper bound links the complexity of their ancilla states with the scaling of their performance. We also show a computer-aided approach to the optimization of such measurement schemes for generic interferometers, by simulating an optical network supplied with various kinds of ancillary input states. We numerically confirms the optimality of known small schemes. We use both methods to investigate other ancilla states, some of them never studied before.

description: We present a study of 581 Hz oscillations observed during a thermonuclear X-ray burst from the low mass X-ray binary (LMXB) 4U 1636-54 with the Rossi X-ray Timing Explorer (RXTE). We argue that the combination of large pulsed amplitudes near burst onset and the spectral evidence for localized emission during the rise strongly supports rotational modulation as the mechanism for the oscillations. We discuss how theoretical interpretation of spin modulation amplitudes, pulse profiles and pulse phase spectroscopy can provide constraints on the masses and radii of neutron stars. We also discuss the implication of these findings for the beat frequency models of kHz X-ray variability in LMXB.

description: Studies of dark energy at advanced gravitational-wave (GW) interferometers normally focus on the dark energy equation of state $w_{\rm DE}(z)$. However, modified gravity theories that predict a non-trivial dark energy equation of state generically also predict deviations from general relativity in the propagation of GWs across cosmological distances, even in theories where the speed of gravity is equal to $c$. We find that, in generic modified gravity models, the effect of modified GW propagation dominates over that of $w_{\rm DE}(z)$, making modified GW propagation a crucial observable for dark energy studies with standard sirens. We present a convenient parametrization of the effect in terms of two parameters $(Ξ_0,n)$, analogue to the $(w_0,w_a)$ parametrization of the dark energy equation of state, and we give a limit from the LIGO/Virgo measurement of $H_0$ with the neutron star binary GW170817. We then perform a Markov Chain Monte Carlo analysis to estimate the sensitivity of the Einstein Telescope (ET) to the cosmological parameters, including $(Ξ_0,n)$, both using only standard sirens, and combining them with other cosmological datasets. In particular, the Hubble parameter can be measured with an accuracy better than $1\%$ already using only standard sirens while, when combining ET with current CMB+BAO+SNe data, $Ξ_0$ can be measured to $0.8\%$ . We discuss the predictions for modified GW propagation of a specific nonlocal modification of gravity, recently developed by our group, and we show that they are within the reach of ET. Modified GW propagation also affects the GW transfer function, and therefore the tensor contribution to the ISW effect.

description: Background: The aim was to determine the association between atrial fibrillation (AF) and outcome in patients undergoing coronary artery bypass grafting (CABG). Methods: All patients undergoing CABG between January 2010 and June 2013 were identified in the Swedish Heart Surgery Registry. Outcomes studied were all-cause mortality, cardiovascular mortality, myocardial infarction, congestive heart failure, ischemic stroke, and recurrent AF. Patients with history of AF prior to surgery (preoperative AF) and patients without history of AF but with AF episodes post-surgery (postoperative AF) were compared to patients with no AF using adjusted Cox regression models. Results: Among 9,107 identified patients, 8.1% (n = 737) had preoperative AF, and 25.1% (n = 2,290) had postoperative AF. Median follow-up was 2.2 years. Compared to no AF, preoperative AF was associated with higher risk of all-cause mortality, adjusted hazard ratio with 95% confidence interval (HR) 1.76 (1.33–2.33); cardiovascular mortality, HR 2.43 (1.68–3.50); and congestive heart failure, HR 2.21 (1.72–2.84). Postoperative AF was associated with risk of all-cause mortality, HR 1.27 (1.01–1.60); cardiovascular mortality, HR 1.52 (1.10–2.11); congestive heart failure, HR 1.47 (1.18–1.83); and recurrent AF, HR 4.38 (2.46–7.78). No significant association was observed between pre- or postoperative AF and risk for myocardial infarction and ischemic stroke. Conclusions: Approximately 1 in 3 patients undergoing CABG had pre- or postoperative AF. Patients with pre- or postoperative AF were at higher risk of all-cause mortality, cardiovascular mortality, and congestive heart failure, but not of myocardial infarction or ischemic stroke. Postoperative AF was associated with higher risk of recurrent AF.
The translation of cultural references in the Italian dubbing of television series
Creators: name: Ranzato, Irene
Publisher: name: Imperial College London
Year: 2013

description: This research describes the strategies adopted by dubbing professionals (mainly translators) in their translations for dubbing of television series, from English into Italian. More specifically, it means to account for the norms governing the work of the translators in this field. In order to draw substantial conclusions, the analysis is conducted on a corpus of television fiction shows, which is not only sufficiently large but also varied in terms of genre, content, language use, and target audiences. The main focus of the analysis is the translation of culture specific references; a subject that has widely been recognised by scholars as being one of the most problematic translation issues, not only in the case of translation for dubbing but also in other areas such as literary and drama translation. One of the hypotheses presented is that the social and historical context in which dubbing originally came to be in Italy had an impact on its subsequent evolution and can still be relevant when dealing with issues of censorship and manipulation of contents. The methodological foundations of this research rest on Toury’s (1980, 1995) notion of norms in translation. Toury (1980: 51) considers norms to be central to the act and the event of translating. The ultimate aim of this study is, therefore, to map out the strategies activated by translators in response to the cultural environment in which they operate, and to detect the norms that are prevalent in the case of dubbing television series into Italian. The analysis is carried out on a corpus of over 95 hours of television programmes, whole episodes of three fiction series belonging to different genres: Friends (sitcom, USA); Life on Mars (science fiction/police procedural drama, UK); Six Feet Under (drama, USA). All the culture specific elements present in the corpus have been detected and their adaptation into Italian analysed from a quantitative and qualitative point of view in order to highlight the prevalent translational behaviours.

description: We present a color-based method for identifying red giants based on Pan-STARRS grz and WISE W1 and W2 photometry. We utilize a subsample of bright stars with precise parallaxes from Gaia DR2 to verify that the color-based selection reliably separates dwarfs from giants. The selection is conservative in the sense that contamination is small (~30%) but not all giants are included (the selection primarily identifies K giants). The color-based selection can be applied to stars brighter than $W1\approx16$, more than two magnitudes fainter than techniques relying on shallower 2MASS photometry. Many streams and clouds are visible in the resulting sky maps, especially when binned by Gaia DR2 proper motions, including the Sagittarius stream, the Hercules-Aquila Cloud, the Eastern Banded Structure, Monoceros, and the Virgo Overdensity. In addition to the characterization of new and known stellar streams, we expect that this method for selecting red giants will enable detailed analysis of the diffuse stellar halo to distances exceeding 100 kpc.

description: This thesis is divided into four chapters. The first chapter comprises an introduction to the fasicularin family of marine alkaloids, and a review of previous total syntheses of the members of this class of compounds. This chapter also covers the previous work by Craig et al. on the synthesis of (±)-lepadiformine, and how this influenced our initial approach to the enantioselective synthesis of (–)-lepadiformine. The second chapter details the first part of our investigation into the synthesis of these compounds, including short reviews of diastereoselective aziridination protocols developed by Yoon et al. and Sharpless et al. This section includes the results of this investigation, and discusses the successes and failures of this approach. The third chapter concerns our revised second-generation strategy for the synthesis of (–)-lepadiformine, and includes a review of the decarboxylative Claisen rearrangement, and diastereoselective variants thereof. This section also covers our results and discussion for this revised synthesis. The fourth chapter contains experimental details and characterisation data for all compounds synthesised.

Electricity and energy price interactions in modern EU markets
Creators: name: Castagneto Gissey, Giorgio
Publisher: name: Imperial College London
Year: 2014

description: This thesis studies the interactions between wholesale electricity prices and various energy and fuel prices, including those of natural gas, coal, oil and EUA carbon permits, in both spot and forward EU markets, during the late years of the noughties boom and the start of the twenty-tens. Chapter 1 introduces the thesis, Chapter 2 provides the necessary background on EU electricity prices and markets, whereas Chapter 3 presents a review of the relevant literature. Chapter 4 uses a nonlinear AR-GARCH approach to analyse the impacts of euro and pound sterling exchange rates (against the USD) and crude oil prices on the levels and volatility of six electricity spot prices. The study finds that electricity price return volatility was asymmetrically affected by both exchange rate and oil price returns in all markets only after the 2008 subprime crisis, which provided a considerably more symmetric response of electricity prices to positive and negative system innovations. Chapter 5 investigates the year-forward interactions between electricity prices and carbon, coal and natural gas prices in four markets via a combination of VAR, Granger-causality and asymmetric AR-GARCH analyses. The study shows that average electricity generators in the Nord Pool and EEX markets pass their carbon costs through to consumers with a ca. 35% higher rate than justified by effective carbon intensity, implying non-competitive practices. Additionally, coal prices are found to be the most influential determinant of European electricity price levels and volatilities. Chapter 6 analyses the integration of a sample of thirteen electricity spot markets. The application of complex network theory enables the creation of an evolving Granger-causal network of electricity price interactions, informing us on the presence of any changes in the normal functioning of electricity markets at both the national and European-wide levels. Finally, Chapter 7 summarises the conclusions of this thesis.

description: The Radical Pair Mechanism is a canonical model for the magnetosensitivity of chemical reaction processes. The key ingredient of this model is the hyperfine interaction that induces a coherent mixing of singlet and triplet electron spin states in pairs of radicals, thereby facilitating magnetic field effects (MFEs) on reaction yields through spin-selective reaction channels. We show that the hyperfine interaction is not a categorical requirement to realize the sensitivity of radical reactions to weak magnetic fields. We propose that, in systems comprising three instead of two radicals, dipolar interactions provide an alternative pathway for MFEs. By considering the role of symmetries and energy level crossings, we present a model that demonstrates a directional sensitivity to fields weaker than the geomagnetic field and remarkable spikes in the reaction yield as a function of the magnetic field intensity; these effects can moreover be tuned by the exchange interaction. Our results further the current understanding of the effects of weak magnetic fields on chemical reactions, could pave the way to a clearer understanding of the mysteries of magnetoreception and other biological MFEs and motivate the design of quantum sensors. Further still, this phenomenon will affect spin systems used in quantum information processing in the solid state and may also be applicable to spintronics.

description: We investigate the non-gaussian properties of cosmic-string-seeded linear density perturbations with cold and hot dark matter backgrounds, using high-resolution numerical simulations. We compute the one-point probability density function of the resulting density field, its skewness, kurtosis, and genus curves for different smoothing scales. A semi-analytic model is then invoked to provide a physical interpretation of our results. We conclude that on scales smaller than $1.5{(Ωh^2)}^{-1}$Mpc, perturbations seeded by cosmic strings are very non-gaussian. These scales may still be in a linear or mildly non-linear regime in an open or $Λ$-universe with $Γ=Ωh \lsim 0.2$.
description: 6 pages, 6 figures; accepted by Ap. J. Lett. With error bars included in the genus curves (figure 3). Also corrected for a minor error in the standard normalization of wavenumbers $k$, resulting from using an incorrect figure for the time $t_{eq}$ of the equal matter-radiation transition given in the Kolb and Turner textbook "The Early Universe". Main conclusions remain unchanged
Association of eating patterns with blood pressure and body mass index: the INTERMAP study
Creators: name: Aljuraiban, Ghadeer
Publisher: name: Imperial College London
Year: 2014

description: Background Epidemiologic evidence is sparse on the role of dietary patterns that may be important drivers of high blood pressure (BP) and body mass index (BMI) levels. Additionally, dietary fibre intake in association with BP and BMI yielded inconsistent results. Objective Investigate the relationships of eating frequency, dietary energy density, diet quality, evening energy intake, GI, GL, and dietary fibre to BP, BMI using cross-sectional data from the INTERnational study on MAcro/micronutrients and blood Pressure (INTERMAP) of 4680 men and women aged 40–59 y from Japan, China, the United Kingdom, and the United States of America. Methods During 4 visits, eight BP, four weight and height measures, four 24-hour dietary recalls, and two 24-hour urine samples were collected. Consumption of all solid foods was aggregated into eating occasions. Nutrient density is expressed using the Nutrient Rich Food index. Multivariable adjusted linear regression models were used to estimate BP and BMI differences per 2SD higher intakes of eating occasions, dietary energy density, Nutrient Rich Food index, evening energy intake, GI, GL, and dietary fibre. Results Compared to participants with <4 eating occasions/24-hours, those with ≥6 eating occasions/24-hours had lower average: systolic BP: 116.4 vs. 121.4 mm Hg; BMI: 27.3 vs. 29.0 kg/m2; total energy: 2127 vs. 2521 kcal/24-hours; dietary energy density: 1.5 vs. 2.2 kcal/g; and higher Nutrient Rich Food index score: 35.1 vs. 26.8. Additionally, insoluble fibre higher by 4 g/1000 was inversely associated with systolic BP (p<0.05), while soluble fibre and GI, GL showed no associations with BP and BMI. Conclusions Results suggest that higher meal frequency may be associated with improved diet quality and lower BP and BMI. Higher intakes of insoluble fibre may contribute to lower BP and BMI. This may have implications for behavioural approaches to controlling high BP levels and the obesity epidemic.

Evolutionary calculations of carbon dredge-up in helium envelope white dwarfs

description: We investigate the evolution of cooling helium atmosphere white dwarfs using a full evolutionary code, specifically developed for following the effects of element diffusion and gravitational settling on white dwarf cooling. The major difference between this work and previous work is that we use more recent opacity data from the OPAL project. Since, in general, these opacities are higher than those available ten years ago, at a given effective temperature, convection zones go deeper than in models with older opacity data. Thus convective dredge-up of observationally detectable carbon in helium atmosphere white dwarfs can occur for thicker helium layers than found by Pelletier et al (1986). We find that the range of observed C to He ratios in different DQ white dwarfs of similar effective temperature is well explained by a range of initial helium layer mass between $10^{-3}$ and $10^{-2} M_{\odot}$, in good agreement with stellar evolution theory, assuming a typical white dwarf mass of $0.6 M_{\odot}$. We also predict that oxygen will be present in DQ white dwarf atmospheres in detectable amounts if the helium layer mass is near the lower limit compatible with stellar evolution theory. Determination of the oxygen abundance has the potential of providing information on the profile of oxygen in the core and hence on the important $^{12}$C$(α,γ)^{16}$O reaction rate.

Effect of silver nanoparticles and microbial ligands on the innate immune response of the human alveolar epithelium
Creators: name: Zambianchi, Marta
Publisher: name: Imperial College London
Year: 2014

description: Over the past decade there has been a rapid increase in the development and use of nanoparticles (NPs, <100nm). Silver (Ag) NPs, due to their antimicrobial activity, are the most commercialised NPs in the world and are incorporated into several consumer goods. However, little is known about the potential adverse effects of AgNPs in humans. Approximately 50% of inhaled NPs preferentially deposit in the alveoli, where alveolar epithelial type-I cells (AT1) form 95% of the alveolar surface, thus constituting a significant target for deposition. We hypothesised that (I) inhalation of AgNPs induces oxidative stress in AT1 cells, leading to a pro-inflammatory response, autophagy activation and DNA damage; (II) in the presence of a microbial infection, AgNP exposure potentiates the innate immune response, leading to increased inflammation and genotoxicity. An immortalised human transformed alveolar type1-like cell line (TT1) was used to investigate these hypotheses. TT1 cells were exposed to AgNPs in the presence/absence of Poly I:C (TLR-3 ligand) and LPS (TLR-4 ligand) prior to assaying cell viability, inflammatory mediator release, oxidative stress, autophagy and DNA damage. AgNPs induced oxidative stress in TT1 cells, as well as inflammation, autophagy activation and DNA damage. The AgNPs-Poly I:C combination further stimulated IL-6 release, DNA damage and delayed autophagic flux, whereas the AgNPs-LPS combination did not. We also discovered two different sources of AgNP-mediated oxidative stress, mitochondria and NADPH oxidase. Pre-treatment of TT1 cells with a TLR-4 inhibitor prevented AgNP-induced inflammation, autophagy activation and DNA damage. On the contrary, TLR-3 inhibition did not affect any of the pathways investigated. In conclusion, we showed that AgNPs induce oxidative stress and act via TLR-4, leading to a pro-inflammatory response, autophagy activation and DNA damage. These cellular pathways are potentiated by co-exposure with Poly I:C. This suggests that inhalation of AgNPs may exert deleterious effects on the lung and, in presence of a viral infection, a worsening of the pulmonary condition.

description: [fol. 109] Mon oncle le receveur part pour Nîmes, Mon cher M. Séguier, et je me hâte de vous écrire, relativement à notre goût commun. J’attends par le courrier d’aujourd’hui un paquet très considérable de graines américaines qui me viennent par la voie des ambassadeurs, mais on m’avertit que les paquets ne sont pas étiquettés attendu que le botaniste envoyé par la cour d’Angleterre aux isles méridionales n’a pu, ou voulu les déterminer ; nous verrons leur produit, si elles réussissent. J’attends votre réponse à mon mémoire avec la plus grande impatience. Joignez Boerhave aux autres livres que je vous ai demandés, Camerarius, Lonicer me sont nécessaires aussi.
La plante cruciforme a fruits ronds et toute ridée que je savais bien ne pas être le Bunias orientalis de Linnae est une plante qu’on m’avait envoyé sous le nom de Bunias Aegyptiaca fructa verrucoso Boerh. J’ai retrouvé la note et vous verrez que le nom de Myagrum orientale crucaginis folio et facie T. Cor. n’était pas le sien mais bien celui de ce Brunias orientalis dont les fruits sont ovés et hinc crassionibus. Linnae n’a pas connu cette espèce. Vous pouvez en garder un échantillon, car je crois y en avoir mis deux. Le synopsis peut-il faire voyage avec les autres livres ? Pouvez-vous encore engager M. Baux à me donner le Lilium flore duplici : folio variegato : la Fritillaria imperialis, l’Hyacinthus muscari flore flavo, qui est de Constantinople. Ce seraient des arres pour les miennes. A-t-il à me donner l’Ornithogalum arabicum que j’ai perdu ?
Notre ami Sauvages est toujours dans le même état et ne voit personne. Vous savez que les états ont presque jugé l’affaire que vous sollicitez ici et que vous risquez de la perdre. Je finis et voudrais que vous ne fussiez pour rien dans le conseil de ville de Nîmes, peut-être en seriez-vous plus libre pour vos amis.
 Je suis certainement celui qui vous est le plus attaché.

 Gouan

A Montpellier le 5 janvier 1767.

Faites, je vous prie partir cette lettre pour l’abbé de Sauvages. Mon oncle ne restera que le lendemain à Nîmes, vous pourriez profiter de ce moment pour m’envoyer au moins votre réponse et mes deux livres qu’il mettra dans sa voiture.
