Through a glass darkly : present and past land-use systems of Papuan sagopalm users

description: This study concerns the application of ethnographic information to the understanding of prehistoric peoples. The ethnography of contemporary sago-using peoples, who inhabit the foothill margin of the deltaic swamps of the Papuan Gulf, and the archaeological evidence recovered from a series of excavated open and rock shelter sites serve as the basis for this work.The Kairi living at Waira Village, who are the focus of my ethnographic research, follow a dual residence system: permanent villages along large rivers and temporary encampments sited near the interior margin of a broad alluvial plain. Their primary subsistence pursuits: sago-making, fishing and hunting follow traditional modes; however, European tools have contributed to some recent alterations. The contemporary Kairi land-use strategy, as interpreted from a time-and-motion study of the VJaira community, is oriented from the location of sagopalm stands, instead of the village site. Taking this information and the observed seasonal flucuations in subsistence and settlement strategies into account I construct a model of contemporary land-use. This analogue and that derived for the contact period are expressed in a series of working and test hypotheses which relate the modelled behavioural patterns to their archaeological reflections. Before considering the archaeological evidence I derive a further set of alternative models from an analysis of other Melanesian sago-using groups. The usefulness of this expanded view of the application of ethnographic analogues - namely the projection of possible prehistoric systems for which there is no evidence in the area today - is demonstrated through model testing. The second part of the thesis considers the archaeological evidence and an assessment against the sui-tes of test hypotheses is made. The results suggest that the occupation of the Waira region extends over approximately the last 3000 years. Subsistence strategies appear to have changed little during that time from what is noted today. Settlement patterns have, however, altered between 1500-1200 BP and from just before European contact to today. This change is marked by the siting of villages along major waterways, repeated use of temporary encampments near the karst escarpment and occurrence of large amounts of exotic commodities. A consideration of the mechanisms of trade and exchange whereby exotic goods reached the Kairi area concludes this thesis. From this analysis I hypothesize that the times when the regional settlement pattern was altered represent intense periods of coastal trade linking sago-producing peoples of the Papuan Gulf with more easterly sited pottery-making communities.

description: Coherent excitation of an ensemble of quantum objects underpins quantum many-body phenomena, and offers the opportunity to realize a quantum memory to store information from a qubit. Thus far, a deterministic and coherent interface between a single quantum system, e.g. a qubit, and such an ensemble has remained elusive. We first use an electron to cool the mesoscopic nuclear-spin ensemble of a semiconductor quantum dot to the nuclear sideband-resolved regime. We then implement an all-optical approach to access these individual quantized electronic-nuclear spin transitions. Finally, we perform coherent optical rotations of a single collective nuclear spin excitation corresponding to a spin wave called a nuclear magnon. These results constitute the building blocks of a dedicated local memory per quantum-dot spin qubit and promise a solid-state platform for quantum-state engineering of isolated many-body systems.

Interaction of [Ru(bpy)2Cl2]·2H2O with one equivalent of 5-chlorosalicylaldehyde in ethanol/N,N′-dimethylformamide afforded the bis(2,2′-bipyridine)ruthenium(II) complex [Ru(bpy)2(κ2-O,O-salCl)](PF6) (2). Complexes 1 and 2 were well characterized by infrared, proton nuclear magnetic resonance spectroscopies along with microanalyses and their molecular structures were determined by single-crystal X-ray diffraction.

description: This report details the synthesis and characterization of six new Mn(II) complexes coordinated to systematically varied 2,2',2''-nitrilotris(N-arylacetamidate) ligands (LR; R = NO2, Cl, Br, H, Me, and OMe). The complexes are synthesized as the di-tetramethylammonium salts [Me4N]2[MnLR(OAc)]. The nitro variant MnNO2 afforded crystals suitable for X-ray diffraction and its molecular structure is reported. We previously reported the crystal structures of FeNO2 and ZnNO2 and additionally report herein the synthesis and characterization of CoNO2. Using these four molecules, we conduct a brief comparison of the bond metrics to demonstrate that the primary difference governing structural changes is likely due to ionic crystal radii changes rather than electronic properties. The electrochemical properties of the MnR complexes were additionally explored with cyclic voltammetry, which revealed that the series is modulated by the various electronic substituents on the aryl groups of the ligands. The electrochemical studies also revealed, consistent with our previous report, that the acetate ligand on the MnR complexes is labile. Finally, a Hammett plot was constructed using the potentials obtained from cyclic voltammetry, which is compared with a few other similar transition metal complexes.

description: The central ideas presented in this study together with most of the work concerned with individual writers and artists have arisen directly from research and reflection upon the primary sources examined. Indebtedness either in the matter of argument or fact has been acknowledged appropriately in the footnotes. Even so it is a pleasant duty to acknowledge that Dr. K. Badt’s John Constable's Clouds , Dr. O. Pacht's 'Early Italian Nature Studies’, and Dr. E. Wind’s ’The Revolution in History Painting' have been found most suggestive and are, in a sense, germinal to the central argument of the study. It will be obvious that it also owes much to Professor A. 0. Lovejoy’s studies in the history of ideas. (First paragraph of Preface).

description: This thesis is concerned with the course of the career of Robert Campbell of the Wharf, colonial merchant, who came from India to New South Wales in 1798 and subsequently established the firm of Campbell and Co. of Sydney. Campbell’s career, which began with some slight knowledge of merchanting and civil affairs in eighteen-century Scotland took him several times between India, England and Australia, as the result of both business and politics, for his career as a merchant involved him in many other activities, which included banking, politics, pastoralism and philanthropy. This narrative is concerned mainly with the effects of Campbell’s trading on the embryo society of New South Wales, traced through the difficulties he encountered in the attempt to trade in a primitive economy. Some attempt has been made to reconstruct his early methods of trading and the volume of that trade. Campbell and Company’s successful attempts to import livestock and their setbacks in the spirit trade show how the Sydney business was related to the trading of the main house in Calcutta. The way in which Campbell was forced to organise and expand some form of colonial export is seen in the development of the colonial fishery. This, in turn, increasingly identified Campbell with colonial aspirations as illustrated by the Lady Barlow’s entry to the Port of London, in defiance of the East India Company’s monopoly. The development of New South Wales’s trade and commerce and its significance in the rebellion against Governor Bligh is outlined, prior to the personal misfortunes which reduced Campbell in 1810 and resulted in the dissolution of the original Indian connection by 1813* Campbell’s return to Australia in 1815 and his attempts (which succeeded by 1827) to re-found a once extensive business coincided with a more active colonial commerce. His contemporaries felt that Campbell’s return to his once unique commercial eminence entitled him to the appellation of 'Father of Australian Commerce' and the merchant after 1827 was diverted into politics as a member of the colonial Legislative Council. From this period until his death in 1846 the emphasis of his life changes after the admission of his sons to partnership in Campbell and Company and with his acquisition of extensive pastoral property.

description: We found a consistent equation of reheating after inflation, which shows that for small quantum fluctuations the frequencies of resonance are slighted different from the standard ones. Quantum interference is taken into account and we found that at large fluctuations the process mimics very well the usual parametric resonance but proceed in a different dynamical way. The analysis is made in a toy quantum mechanical model and we discuss further its extension to quantum field theory.

description: A new organic-inorganic hybrid material, CoCl2N,N'-(1,2-phenylene)bis(2-aminobenzamide)@Al-SBA-15, was synthesized by modification of Al-SBA-15 with (3-chloropropyl) trimethoxysilane (CPTMS), then the ligand was covalently attached to CPTMS@Al-SBA-15 and finally addition of CoCl2 to form the complex. The mesoporous CoCl2NN'PhBIA@Al-SBA-15 was an efficient catalyst in the preparation of 3-benzoxazol-2-yl-chromen-2-one derivatives through reaction of different coumarin-3-carboxylates and 2-aminophenol derivatives. The nanocatalyst increased rate and facility of the aforementioned reaction and had influence in the green synthesis of different 3-benzoxazol-2-yl-2H-chromen-2-one derivatives. The nanocatalyst was characterized by N2 adsorption–desorption, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), powder X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS). Some advantages of this procedure are mild reaction condition, high yields of 3-benzoxazol-2-yl-2H-chromen-2-one, short reaction times, environmentally benign, recoverability of the catalyst and reusability without significant loss of its catalytic performance.

description: A generalized analysis of the local entropy production of a simple fluid is used to show that, if intrinsic angular momentum is taken into account, rotational viscosity must arise in the linear non-equilibrium regime. As a consequence, the stress tensor of dense rotating matter, such as the one present in neutron stars, posseses a significant non-vansishing antisymmetrical part. A simple argument suggests that, due to the extreme magnetic fields present in neutron stars, the relaxation time associated to rotational viscosity is large (approx 10^{21} s). The formalism leads to generalized Navier-Stokes equations useful in neutron star physics which involve vorticity in the linear regime.

description: We examine the magnetic interference patterns of Josephson junctions with a region of 0- and of pi-phase shift. Such junctions have recently been realized as c-axis YBCO-Pb junctions with a single twin boundary in YBCO. We show that in general the junction generates self-fields which introduces an asymmetry in the critical current under reversal of the magnetic field. Numerical calculations of these asymmetries indicate they account well for the unexplained features observed in single twin boundary junctions.

description: The Opalinidae are a group of protozoa inhabiting the rectum of Anura. The systematics of the group has been the subject of much controversy. Metcalf's view (Metcalf, 1918), that the Opalinidae represent a primitive stage in the evolution of the Ciliata, has been discredited by more recent workers. A series of papers, culminating with that of Grasse (1952), has pointed out the affinities of the Opalinidae with the Flagellates. Grasse (op. cit.) created a new super-order Opalinina at the same level as the Protomonadina and Metamonadina, clearly indicating his view of their specialized evolution from existing flagellates. Corliss (1955) summarized the ciliate and the flagellate characters of the Opalinidae and agreed with Grasse as regards their specialized flagellate affinities. For these reasons the Order Protociliata of Metcalf (op. cit.) has been discarded.

description: A key challenge in origins-of-life studies is estimating the abundances of species relevant to the chemical pathways proposed to have contributed to the emergence of life on early Earth. Dissolved nitrogen oxide anions (NO$_{X}^{-}$), in particular nitrate (NO$_{3}^{-}$) and nitrite (NO$_{2}^{-}$), have been invoked in diverse origins-of-life chemistry, from the oligomerization of RNA to the emergence of protometabolism. Recent work has calculated the supply of NO$_{X}^{-}$ from the prebiotic atmosphere to the ocean, and reported steady-state [NO$_{X}^{-}$] to be high across all plausible parameter space. These findings rest on the assumption that NO$_{X}^{-}$ is stable in natural waters unless processed at a hydrothermal vent. Here, we show that NO$_{X}^{-}$ is unstable in the reducing environment of early Earth. Sinks due to UV photolysis and reactions with reduced iron (Fe$^{2+}$) suppress [NO$_{X}^{-}$] by several orders of magnitude relative to past predictions. For pH$=6.5-8$ and $T=0-50^\circ$C, we find that it is most probable that NO$_{X}^{-}$]$<1~μ$M in the prebiotic ocean. On the other hand, prebiotic ponds with favorable drainage characteristics may have sustained [NO$_{X}^{-}$]$\geq 1~μ$M. As on modern Earth, most NO$_{X}^{-}$ on prebiotic Earth should have been present as NO$_{3}^{-}$, due to its much greater stability. These findings inform the kind of prebiotic chemistries that would have been possible on early Earth. We discuss the implications for proposed prebiotic chemistries, and highlight the need for further studies of NO$_{X}^{-}$ kinetics to reduce the considerable uncertainties in predicting [NO$_{X}^{-}$] on early Earth.

Factors involved in the release of transmitter substances at mammalian junctional regions

description: The subject under investigation in this thesis presupposes that transmission across junctional regions is by means of a chemical substance- a transmitter. The basic idea of chemical transmission, that a nerve impulse releases a chemical substance from nerve endings, is now more than fifty years old,. In its genesis, proof and development many have been concerned, but the contributions of Elliott, Loewi and Dale have proved outstanding. It was Elliott (1904,1905) who, struck by the resemblance between the effects of adrenaline and sympathetic nerve stimulation, suggested that nerve endings might liberate a chemical substance which 'could act on a cell to modify its existing activity or start a new event.' (First paragraph of Introduction).

description: Single-crystals of binuclear neutral sulfur-nitrosyl iron complex with 2-mercaptobenzthiazole ligand [Fe2(С7н4NS2)2(NO)4] (BTz) have been obtained. From X-ray data, BTz has a centrosymmetric dimeric structure, with the iron atoms being linked through the µ-N-C-S bridge. As follows from mass-spectra of the BTz gas phase, the complex is stable in the crystalline state under normal conditions (ambient temperature and standard humidity) and releases nitric oxide upon heating. Using amperometry, kinetics of NO release by BTz in 1% dimethyl sulfoxide aqueous solution has been studied: release of NO was shown to occur immediately upon dissolution in protic media. BTz inhibited growth of K562 leukemia and SKOV3 ovarian carcinoma cells in vitro and induced apoptosis via activation caspases 3 and 7.

description: We report the discovery of X-ray emission from NGC 7027, a prototypical object for the study of the formation and evolution of planetary nebulae (PNs). Observations with the Advanced CCD Imaging Spectrometer (ACIS) aboard the Chandra X-ray Observatory show that the X-ray emission from NGC 7027 is extended and is bipolar in morphology. The ACIS spectrum displays strong emission from highly ionized Ne and weaker emission features which we attribute to O, Mg, and Si. Model fits to this spectrum suggest a characteristic temperature T_x ~ 3x10^6 K and an intrinsic (unabsorbed) X-ray luminosity of L_x ~ 1.3x10^32 ergs/s. The intranebular absorption of X-ray emission is highly nonuniform, but the modeling indicates an average column density N_H ~ 6x10^21 cm^-2, consistent with previous measurements of relatively large visual extinction within the nebula. We suggest that the X-ray emission from NGC 7027 is or was generated by a hitherto undetected fast wind from the central star of NGC 7027, or from a companion to this star. Chandra's detection of extended, high-temperature X-ray emission from BD +30 3639, NGC 6543, and now NGC 7027 suggests that such emission is a common feature of young planetary nebulae.

description: By applying renormalization group method to the bosonized Hamiltonian of two-coupled chains with repulsive intrachain interaction, we have examined a role of backward scattering with a spin-anisotropy which competes with interchain hopping. From calculation of a dominant state in the limit of low energy, it is found that superconducting state moves into spin density wave state when the anisotropy becomes larger than a critical value. Further phase diagram is shown on the plane of g-ology.

description: The object of this thesis is to present a formal theory for the seasonal adjustment of a single series in terms of spectral analysis, that is, the analysis of frequency components, together with a practical illustration. Instead of describing the well-know classical procedures we refer the reader to two quite sophisticated examples, the work of the Bank Deutscher Lander (1957) and Shiskin and Eisenpress (1957). It will appear that the spectral method is more powerful for description and analysis than are the classical methods, since it decomposes variables into their fundamental component parts; the estimation of variances and tests of significance are thus greatly facilitated.

description: The widespread clinical use of antibiotics was one of the most important advancements in medicine during the 1900’s, increasing the average human lifespan and allowing for other progressions in modern medicine. However, due to human misuse in combination with bacterial dissemination mechanisms, the rise of antibiotic resistance in bacteria has become a global threat. A prevalent method of resistance in bacteria is the expression of antibiotic-modifying enzymes. 6′-N-acetyltransferase type Ib [AAC(6′)-Ib] is one such enzyme that inactivates aminoglycosides, a broad-spectrum class of antibiotics, and is ubiquitous, found in mobile genetic elements and in chromosomal DNA. The antibiotic pipeline is greatly waning, and the development of new antibiotics cannot keep up with the spread of antimicrobial resistance.

A strategy to combat bacterial resistance to antibiotics that circumvents many of the hurdles of antibiotic development is the use of adjuvants to restore or enhance efficacy of existing antibiotics. In this study, adjuvants that inhibit the acetylation reaction of AAC(6’)-Ib such as metal ions for antibiotic protection, small molecule inhibitors for enzyme inhibition, and antisense oligonucleotides for mRNA steric hindrance are assessed in combinations of two in their inhibition of Acinetobacter baumannii, a Gram-negative ESKAPE pathogen. Results demonstrated that the relationships were additive and there was not a statistically significant difference between the inhibition by one adjuvant and two adjuvants. Secondly, another adjuvant, external guide sequences, are optimized with the incorporation of bridged nucleic acids to increase their RNase P and RNase H-mediated cleavage of aac(6’)-Ib mRNA. The LNA EGS elicited the highest average degradation percent, with 98% for RNase P and 72% for RNase H.

In particular we study the hexaboride NdB_6 which is shown to exhibit strong spin-quadrupolar coupling. The CEF scheme is analyzed and a non-collinear magnetization response is found. The spin orientation in the antiferromagnetically ordered ground-state is identified. Moreover, the spin excitations are evaluated and in agreement with inelastic neutron scattering a suppression of one of the two magnetic modes in the strong-coupling regime is predicted.

description: Blue horizontal-branch stars are Population II objects which are burning helium in their core and possess a hydrogen-burning shell and radiative envelope. Because of their low rotational velocities, diffusion has been predicted to work in their atmospheres. In many respects, blue horizontal-branch stars closely resemble the magnetic chemically peculiar stars of the upper main sequence, which show photometric variability caused by abundance spots on their surfaces. These spots are thought to be caused by diffusion and the presence of a stable magnetic field. However, the latter does not seem to be axiomatic. We searched for rotationally induced variability in 30 well-established bright field blue horizontal-branch stars in the solar neighbourhood and searched the literature for magnetic fields measurements of our targets. We employed archival photometric time series data from the ASAS, ASAS-SN, and SuperWASP surveys. The data were carefully reduced and processed, and a time series analysis was applied using several different techniques. We also synthesized existing photometric and spectroscopic data of magnetic chemically peculiar stars in order to study possible different surface characteristics producing lower amplitudes. In the accuracy limit of the employed data, no significant variability signals were found in our sample stars. The resulting upper limits for variability are given. We conclude that either no stellar surface spots are present in field blue horizontal-branch stars, or their characteristics (contrast, total area, and involved elements) are not sufficient to produce amplitudes larger than a few millimagnitudes in the optical wavelength region. New detailed models taking into account the elemental abundance pattern of blue horizontal-branch stars are needed to synthesize light curves for a comparison with our results.

Opsiphanes quiteria

description: Opsiphanes quiteria (Stoll, 1780)
(Figs 134–161)
 Diagnosis. The male of Opsiphanes quiteria has the DFW with an oblique whitish, yellow, or orange band, at least twice the width of the DFW oblique band of Opsiphanes badius stat. rest., a closely related species, this band also has a regular distal margin, and the CuA 2 -2A portion is usually wider in Opsiphanes quiteria than in Opsiphanes quirinus stat. rest., another closely related species (Fig. 134a). The female of Opsiphanes quiteria quirinalis is similar to females of Opsiphanes badius stat. rest. and Opsiphanes quirinus stat. rest. in having the DFW with an oblique whitish band, but differs from them in having the DHW without a rusty red color in the postdiscal region, between M 2 and CuA 2 (Fig. 145a). Females of Opsiphanes quiteria quiteria and Opsiphanes quiteria meridionalis have the DFW with an oblique yellow band (Fig. 138a), distinguishing them from females of Opsiphanes badius stat. rest. and Opsiphanes quirinus stat. rest. Molecular analyses recovered Opsiphanes quiteria as closely related to Opsiphanes badius stat. rest. and Opsiphanes quirinus stat. rest. (Fig. 2) (genetic distance 1.9–2.5% and 1.4–2.1%, respectively).
 Male genitalia. Tegumen in dorsal view with anterior margin with a small concavity in the median region and anterior margin wider than the posterior margin; anterior projection of saccus in lateral view almost twice as long as dorsal arms of saccus (Fig. 146).
 Female genitalia. Lamella antevaginalis membranous medially and sclerotized laterally; lamella postvaginalis as a W-shaped plate; ostium membranous (Fig. 147).
 Variation. Subspecies vary in the following characters: DHW, with or without a yellow spot of variable length near the distal margin of the humeral cell. VFW, EIII submarginal line exceeds or not CuA 1. VHW, the size of the eyespot between Sc+R 1 and M 1, and the width of its dark-brown ring; size and shape of the eyespot between M 3 and CuA 2; the postdiscal region with or without small light-brown spots between M 1 and CuA 1; and the zigzag EIII submarginal line not always evident (Figs 134–145).
 Comments. Opsiphanes quiteria is sympatric with Opsiphanes invirae and differs in having the HW with a crenulated outer margin; DHW, near the distal margin of the humeral cell, usually with a yellow spot of variable length, and VHW with a marbled pattern.

description: The temperature dependence of electron spin polarization for a narrow quantum Hall system shows behavior analogous to that of a two-dimensional system at major filling factors. At the lowest half-filled quantum Hall state for which no two-dimensional analog exists, we find a stable spin partially-polarized system. Periodic Gaussian repulsive impurities (antidots) in such a system leads to novel spin transitions at $ν=\frac13$ and $ν=\frac12$ and the pair-correlation functions provide clues about nature of different ground states in the system. These results can be explored in optical spectroscopy and optically pumped NMR Knight shift measurements.

description: The curved spacetime surrounding a rotating black hole dramatically alters the structure of nearby electromagnetic fields. The Wald field which is an asymptotically uniform magnetic field aligned with the angular momentum of the hole provides a convenient starting point to analyze the effects of radiative corrections on electrodynamics in curved spacetime. Since the curvature of the spacetime is small on the scale of the electron's Compton wavelength, the tools of quantum field theory in flat spacetime are reliable and show that a rotating black hole immersed in a magnetic field approaching the quantum critical value of $B_k=m^2 c^3/(e\hbar) \approx 4.4 \times 10^{13}$~G $\approx 1.3\times10^{-11}$ cm$^{-1}$ is unstable. Specifically, a maximally rotating three-solar-mass black hole immersed in a magnetic field of $2.3 \times 10^{12}$~G would be a copious producer of electron-positron pairs with a luminosity of $3 \times 10^{52}$ erg s$^{-1}$.

description: The present study offers an historical outline of the antecedents, establishment and growth of the London Wool Terminal Market. It also examines the problem whether in the long run either side of the market made significant gains. The analysis undertaken indicates that operators maintaining long positions would have made gross profits and certain groups among them also net profits. The findings are broadly consistent with the Keynesian theory of normal backwardation. The absence of definite normal backwardation for close maturities can be explained as the effect of hedgers leaving the market in that phase of their futures' maturity. The interpretation of a price pattern which permits systematic transfers from one group of operators to another as evidence for the payment of a risk premium may be criticized by those who minimize the importance of risk avoidance in hedgers' motivation. How ever, statistics on motivation are even harder to come by than in formation on a great many other factors in futures trading of a less ambiguous nature. If the statistical analysis is accepted, the risk-premium interpretation seems not only the most abvious but the only plausible one. References have been confined to writings bearing directly on the argument and no systematic or historical survey of the literature dealing with the theory of futures trading has been attempted, as this would easily have usurped the role of the main subject.

description: We report on the position, timing, and energy resolution of a range of plastic scintillator bars and reflector treatments using dual-ended silicon photomultiplier readout. These measurements are motivated by the upcoming construction of an optically segmented single-volume neutron scatter camera, in which neutron elastic scattering off of hydrogen is used to kinematically reconstruct the source direction and energy of an incoming neutron. For this application, interaction position resolutions of about 10 mm and timing resolutions of about 1 ns are necessary to achieve the desired efficiency for fission-energy neutrons. The results presented here indicate that this is achievable with an array of $5\times5\times190~\mathrm{mm}^3$ bars of EJ-204 scintillator wrapped in Teflon tape, read out with SensL's J-series $6\times6~\mathrm{mm}^2$ silicon photomultipliers. With two independent setups, we also explore the systematic variability of the position resolution, and show that, in general, using the difference in the pulse arrival time at the two ends is less susceptible to systematic variation than using the log ratio of the charge amplitude of the two ends. Finally, we measure a bias in the absolute time of interactions as a function of position along the bar: the measured interaction time for events at the center of the bar is $\sim$100 ps later than interactions near the SiPM.

description: The black hole candidate MAXI J1836-194 was discovered in 2011 when it went into an outburst, and was the subject of numerous, quasi-simultaneous, multi-wavelength observations in the radio, infrared, optical and X-rays. In this paper, we model its multi-wavelength radio to optical spectral energy distributions (SEDs) with an internal shock jet model. The jet emission is modelled on five dates of the outburst, during which the source is in the hard and hard intermediate X-ray spectral states. The model assumes that fluctuations of the jet velocity are driven by the variability in the accretion flow which is traced by the observed X-ray timing properties of the source. While the global shape of the SED is well reproduced by this model for all the studied observations, the variations in bolometric flux and typical energies require at least two parameters to evolve during the outburst. Here we investigate variations of the jet power and mean Lorentz factor, which are both found to increase with the source luminosity. Our results are compatible with the evolution of the jet Lorentz factor reported in earlier studies of this source. However, due to the large degeneracy of the parameters of the ishem model, our proposed scenario is not unique.
