description: Centralized communication-based control is one of the main methods that can be implemented to achieve autonomous advanced energy management capabilities in DC microgrids. However, its major limitation is the fact that communication bandwidth and computation resources are limited in practical applications. This can be often improved by avoiding redundant communications and complex computations. In this paper, an autonomous communication-based hybrid state/event driven control scheme is proposed. This control scheme is hierarchical and heuristic, such that on the primary control level, it encompasses state-driven local controllers, and on the secondary control level, an event-driven MG centralized controller (MGCC) is used. This heuristic hybrid control system aims at reducing the communication load and complexity, processor computations, and consequently system cost while maintaining reliable autonomous operation during all possible scenarios. A mathematical model for the proposed control scheme using Finite State Machines (FSM) has been developed and used to cover all the possible modes/sub-modes of operation, and assure seamless transitions among them during various events. Results of some case studies involving severe operational scenarios were presented and discussed. Results verify the validity and effectiveness of the proposed communication-based control scheme

description: Visualisation of data is critical to understanding astronomical phenomena. Today, many instruments produce datasets that are too big to be downloaded to a local computer, yet many of the visualisation tools used by astronomers are deployed only on desktop computers. Cloud computing is increasingly used to provide a computation and simulation platform in astronomy, but it also offers great potential as a visualisation platform. Virtual hosted desktops, with graphics processing unit (GPU) acceleration, allow interactive, graphics-intensive desktop applications to operate co-located with astronomy datasets stored in remote data centres. By combining benchmarking and user experience testing, with a cohort of 20 astronomers, we investigate the viability of replacing physical desktop computers with virtual hosted desktops. In our work, we compare two Apple MacBook computers (one old and one new, representing hardware and opposite ends of the useful lifetime) with two virtual hosted desktops: one commercial (Amazon Web Services) and one in a private research cloud (the Australian Nectar Research Cloud). For two-dimensional image-based tasks and graphics-intensive three-dimensional operations -- typical of astronomy visualisation workflows -- we found that benchmarks do not necessarily provide the best indication of performance. When compared to typical laptop computers, virtual hosted desktops can provide a better user experience, even with lower performing graphics cards. We also found that virtual hosted desktops are equally simple to use, provide greater flexibility in choice of configuration, and may actually be a more cost-effective option for typical usage profiles.

description: We study the relation between Chern numbers and Quantum Phase Transitions (QPT) in the XY spin-chain model. By coupling the spin chain to a single spin, it is possible to study topological invariants associated to the coupling Hamiltonian. These invariants contain global information, in addition to the usual one (obtained by integrating the Berry connection around a closed loop). We compute these invariants (Chern numbers) and discuss their relation to QPT. In particular we show that Chern numbers can be used to label regions corresponding to different phases.

description: The Lockman Hole field represents the sky area of lowest Galactic line-of-sight column density N_H=5.7X10^19 cm^-2. It was observed by the XMM-Newton X-ray observatory in 18 pointings for a total of 1.16 Msec (raw EPIC pn observing time) constituting the deepest XMM-Newton exposure so far. We present a catalogue of the X-ray sources detected in the central 0.196 deg^2 of the field and discuss the derived number counts and X-ray colours. In the 0.5--2.0 keV band, a sensitivity limit (defined as the faintest detectable source)of 1.9X10^-16 erg cm^-2 s^-1 was reached. The 2.0--10.0 keV band and 5.0--10.0 keV band sensitivity limits were 9X10^-16 erg cm^-2 s^-1 and 1.8X10^-15 erg cm^-2 s^-1, respectively.A total of 409 sources above a detection likelihood of 10 (3.9 sigma) were found within a radius of 15' off the field centre, of which 340, 266, and 98 sources were detected in the soft, hard, and very hard bands, respectively. The number counts in each energy band are in close agreement with results from previous surveys and with the synthesis models of the X-ray background. A 6% of Compton-thick source candidates have been selected from the X-ray colour-colour diagram. This fraction is consistent with the most recent predictions of X-ray background population synthesis models at our flux limits. We also estimated, for the first time, the logN-logS relation for Compton-thick AGN.

Making do Without Spectroscopy: Using Computational Models to Uncover Parameter Correlations in Binary Stars

Subjects: Stars, binary stars, eclipsing binary stars

description: The analysis of eclipsing binary star systems provides one of the most reliable methods of accurately estimating physical stellar parameters. However, when given photometric observations of a binary, the process of identifying which parameters best describe that system often proves difficult. This issue is further compounded for faint star systems where it is challenging to obtain stellar spectra. Here we present modelling of three binary systems observed with Kepler using the Physics of Eclipsing Binaries (PHOEBE) software package. Markov Chain Monte Carlo methods were used to evaluate the goodness of fit of our synthetic observables to photometric data gathered by the Kepler mission. We also seek to demonstrate the feasibility of constraining physical parameters using only photometric data, especially for those systems where spectroscopic data is difficult to obtain. Although we cannot completely constrain the parameters of systems for which we lack spectroscopic information, MCMC analysis provides knowledge of the correlations between the parameters of our model. We will discuss our findings along with the limits of what we can achieve using only photometric data.

description: Motivated by recent experimental realizations of topological edge states in Su-Schrieffer-Heeger (SSH) chains, we theoretically study a ladder system whose legs are comprised of two such chains. We show that the ladder hosts a rich phase diagram and related edge mode structure dictated by choice of inter-chain and intra-chain couplings. Namely, we exhibit three distinct physical regimes: a topological hosting localized zero energy edge modes, a topologically trivial phase having no edge mode structure, and a regime reminiscent of a weak topological insulator having unprotected edge modes resembling a "twin-SSH" construction. In the topological phase, the SSH ladder system acts as an analog of the Kitaev chain, which is known to support localized Majorana fermion end modes, with the difference that bound states of the SSH ladder having the same spatial wavefunction profiles correspond to Dirac fermion modes. Further, inhomogeneity in the couplings can have a drastic effect on the topological phase diagram of the ladder system. In particular for quasiperiodic variations of the inter-chain coupling, the phase diagram reproduces Hofstadter's butterfly pattern. We thus identify the SSH ladder system as a potential candidate for experimental observation of such fractal structure.

A model of the Mira-type star T UMi

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Stellar evolution calculations were carried out from the main sequence to the final AGB stage of stars with initial masses from 1 to $2M_\odot$ and metallicity $Z=0.01$. Selected models of evolutionary sequences were used as initial conditions for solution of the equations of radiation hydrodynamics and time-dependent convection describing radial stellar pulsations. The study was aimed to construct the hydrodynamic models of Mira-type stars that show the secular decrease in the pulsation period commenced in 1970--th at $Π=315$ day. We show that such a condition for the period change is satisfied with evolutionary sequences from 1 to $1.2M_\odot$ and the best agreement with observations is obtained for models with initial mass $1.2M_\odot$. The pulsation period reduction is due to both the stellar radius decrease during the thermal pulse of the helium burning shell and mode switch from the fundamental mode to the first overtone. Theoretical estimates of the fundamental parameters of the star at the onset of pulsation period reduction are as follows: the mass is $M=0.93M_\odot$, the luminosity is $L = 4080L_\odot$, and the radius is $R=220R_\odot$. The mode switch occurs 35 years after the onset of period reduction.

description: The presence of unseen halos of ``dark matter'' has long been inferred from the high rotation speeds of gas and stars in the outer parts of spiral galaxies$^{1}$. The volume density of this dark matter decreases less quickly from the galactic center than does that of the luminous mass (such as that in stars), meaning that the dark matter dominates the mass far from the center$^{1,2}$. While searching for faint starlight away from the plane of the edge-on disk galaxy \gal$^{3}$, we have found that the galaxy is surrounded by a faint luminous halo. The intensity of light from this halo falls less steeply than any known luminous component of spiral galaxies, but is consistent with the distribution of dark mass inferred from the galaxy's rotation curve.

description: We apply three optical coherence tomography (OCT) image analysis techniques to extract morphometric information from OCT images obtained on peripheral nerves of rat. The accuracy of each technique is evaluated against histological measurements accurate to +/-1 um. The three OCT techniques are: 1) average depth resolved profile (ADRP); 2) autoregressive spectral estimation (AR-SE); and, 3) correlation of the derivative spectral estimation (CoD-SE). We introduce a scanning window to the ADRP technique which provides transverse resolution, and improves epineurium thickness estimates - with the number of analysed images showing agreement with histology increasing from 2/10 to 5/10 (Kruskal-Wallis test, α = 0.05). A new method of estimating epineurium thickness, using the AR-SE technique, showed agreement with histology in 6/10 analysed images (Kruskal-Wallis test, α = 0.05). Using a tissue sample in which histology identified two fascicles with an estimated difference in mean fibre diameter of 4 um, the AR-SE and CoD-SE techniques both correctly identified the fascicle with larger fibre diameter distribution but incorrectly estimated the magnitude of this difference as 0.5um. The ability of OCT signal analysis techniques to extract accurate morphometric details from peripheral nerve is promising but restricted in depth by scattering in adipose and neural tissues.

description: This article analyses how government funding affects the interactions interest organisations initiate with governments in a multi-level context. Governments rarely write blank checks, but rather specify eligibility and spending requirements when funding interest organisations. Our primary argument is that these requirements do not only impact organisations’ interactions with their benefactors, but that they may also impact interactions with governments at other levels. We analyse this expectation drawing data from a recent survey of a representative sample of Belgian interest organisations. Our results demonstrate that organisations dependent on funding from the subnational and European level are less prone to interact with the national government. Whereas, organisations dependent on national government funding are not less likely to contact the subnational level of government. This variation is explained by the various ways these respective governments implement discretion.

description: We present a novel deep learning architecture to address the natural language inference (NLI) task. Existing approaches mostly rely on simple reading mechanisms for independent encoding of the premise and hypothesis. Instead, we propose a novel dependent reading bidirectional LSTM network (DR-BiLSTM) to efficiently model the relationship between a premise and a hypothesis during encoding and inference. We also introduce a sophisticated ensemble strategy to combine our proposed models, which noticeably improves final predictions. Finally, we demonstrate how the results can be improved further with an additional preprocessing step. Our evaluation shows that DR-BiLSTM obtains the best single model and ensemble model results achieving the new state-of-the-art scores on the Stanford NLI dataset.

description: The screening properties of fullerene molecules are described by means of a continuum model which uses the electronic wavefunctions of planar graphite as a starting point. The long distance behavior of the system gives rise to a renormalizable theory, which flows towards a non trivial fixed point. Its existence implies an anomalous dielectric constant. The screening properties are neither metallic nor insulating. Alternatively, the intramolecular screening is obtained from a simple approximation to the electronic wavefunctions. Intermolecular effects are also calculated. As a consistency check, it is shown that the observed polarizability of C$_{60}$ is well eproduced.

description: We use the UV-optical color magnitude diagram in combination with spectroscopic and photometric measurements derived from the SDSS spectroscopic sample to measure the distribution of galaxies in the local universe (z<0.25) and their physical properties as a function of specific star formation rate (SSFR) and stellar mass. Throughout this study our emphasis is on the properties of galaxies on and off of a local "star-forming sequence." We discuss how the physical characteristics of galaxies along this sequence are related to scaling relations typically derived for galaxies of different morphological types. We find, among other trends that our measure of the star formation rate surface density is nearly constant along this sequence. We discuss this result and implications for galaxies at higher redshift. For the first time, we report on measurements of the local UV luminosity function versus galaxy structural parameters as well as inclination. We also split our sample into disk-dominated and bulge-dominated subsamples using the i-band Sersic index and find that disk-dominated galaxies occupy a very tight locus in SSFR vs. stellar mass space while bulge-dominated galaxies display a much larger spread of SSFR at fixed stellar mass. A significant fraction of galaxies with SSFR and SF surface density above those on the "star-forming sequence" are bulge-dominated. We can use our derived distribution functions to ask whether a significant fraction of these galaxies may be experiencing a final episode of star formation (possibly induced by a merger or other burst), soon to be quenched, by determining whether this population can explain the growth rate of the non-star-forming galaxies on the "red sequence."

description: The current artistic and academic interest in the archive of militant cinemas within the contemporary discourse on the urgency of decolonization is the starting point for this analysis of Sarah Maldoror’s first feature Sambizanga (1972). Set right on the brink of the beginning of the armed struggle for independence in Angola in 1961, the film focuses on a woman’s search for her imprisoned husband and 'the time it takes to march' (Evan 1973). This essay aims at showing how Maldoror develops a unique way of seeing in Sambizanga that seems to have the potential to open up what Achille Mbembe (2017) calls 'the dungeon of appearances', by telling a story of the process of leaving the 'dark night' of colonialism (Fanon 1963, Andrade and Ollivier 1971, Mbembe 2021). By reading the film’s decolonial aesthetics in dialogue with Fanon’s theory of decolonization, and with reference to Mbembe and Kara Keeling, I trace the aesthetic approach to decolonizing temporality and visibility, bringing to the fore the argument that Maldoror achieves nothing less than what I would like to call a caring gaze, which seems to extend the logic of representation and recognition (by international audiences), and instead can be seen as a work of repair.

description: We present a new calculation of the CP violation parameter $ε^{\prime}/ ε$. The results reported in this paper have been obtained by using the $ΔS=1$ effective Hamiltonian computed at the next-to-leading order, including QCD and QED penguins. The matrix elements of the relevant operators have been taken from lattice QCD, at a scale $μ=2$ GeV. At this relatively large scale, the perturbative matching between the relevant operators and the corresponding coefficients is quite reliable. The effect of the next-to-leading corrections is to lower the prediction obtained at the leading order, thus favouring the experimental result of E731. We analyze different contributions to the final result and compare the leading and next-to-leading cases.

First Observations of Individual Molecular Clouds in the Irregular Galaxy NGC 6822

Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Three molecular clouds have been mapped in the nearby metal-poor dwarf irregular galaxy NGC 6822 using the Owens Valley Millimeter-Wave Interferometer. Based on upper limits to the virial masses of the clouds, the CO-to-H2 conversion factor in NGC 6822 is <2.2+/-1.3 times larger than the Galactic value. Conversion factors obtained for Galactic molecular clouds, NGC 6822, and the SMC are consistent with the variation in the CO-to-H2 conversion factor being linearly proportional to the oxygen abundance of the galaxy. However, the uncertainties are sufficiently large that equal conversion factors in NGC 6822 and the Galaxy cannot be ruled out. The gas depletion time obtained for the HII region Hubble V is comparable to those of giant HII regions in M33. Thus high-efficiency star formation is not limited to the giant HII regions seen spiral galaxies, but can also occur in a small group of relatively low-mass molecular clouds.

description: We propose the analog quantum simulation of generalized Dicke models in trapped ions. By combining bicromatic laser interactions on multiple ions we can generate all regimes of light-matter coupling in these models, where here the light mode is mimicked by a motional mode. We present numerical simulations of the three-qubit Dicke model both in the weak field (WF) regime, where the Jaynes-Cummings behaviour arises, and the ultrastrong coupling (USC) regime, where rotating-wave approximation (RWA) cannot be considered. We also simulate the two-qubit biased Dicke model in the WF and USC regimes and the two-qubit anisotropic Dicke model in the USC regime and the deep-strong coupling (DSC) regime. The agreement between the mathematical models and the ion system convinces us that these quantum simulations can be implemented in the lab with current or near-future technology. This formalism establishes an avenue for the quantum simulation of many-spin Dicke models in trapped ions.

description: None of the 1000 solar models in a full Monte Carlo simulation is consistent with the results of the chlorine or the Kamiokande experiments. Even if the solar models are forced artifically to have a \b8 neutrino flux in agreeement with the Kamiokande experiment, none of the fudged models agrees with the chlorine observations. The GALLEX and SAGE experiments, which currently have large statistical uncertainties, differ from the predictions of the standard solar model by $2 σ$ and $3 σ$, respectively.

description: If the Sun was born in a relatively compact open cluster, it is quite likely that a massive (10MSun) star was nearby when it exploded in a supernova. The repercussions of a supernova can be rather profound, and the current Solar System may still bear the memory of this traumatic event. The truncation of the Kuiper belt and the tilt of the ecliptic plane with respect to the Sun's rotation axis could be such signatures. We simulated the effect of a nearby supernova on the young Solar System using the Astronomical Multipurpose Software Environment. Our calculations are realized in two subsequent steps in which we study the effect of the supernova irradiation on the circumstellar disk and the effect of the impact of the nuclear blast-wave which arrives a few decades later. We find that the blastwave of our adopted supernova exploding at a distance of $0.15$--$0.40$\,pc and at an angle of $35^\circ$--$65^\circ$ with respect to the angular-momentum axis of the circumsolar disk would induce a misalignment between the Sun's equator and its disk to $5^\circ.6\pm1^\circ.2$, consistent with the current value. The blast of a supernova truncates the disk at a radius between $42$ and $55$\,au, which is consistent with the current edge of the Kuiper belt. For the most favored parameters, the irradiation by the supernova as well as the blast wave heat the majority of the disk to $\sim 1200$\,K, which is sufficiently hot to melt chondrules in the circumstellar disk. The majority of planetary system may have been affected by a nearby supernova, some of its repercussions, such as truncation and tilting of the disk, may still be visible in their current planetary system's topology. The amount of material from the supernova blast wave that is accreted by the circumstellar disk is too small by several orders of magnitude to explain the current abundance of the short live radionuclide $^{26}$Al.

Subjects: Frieden, Krieg, Geschichte, Friedensbegriffe, Innere Sicherheit, Äußere Sicherheit, Friedensansätze, Friedenskultur, Friedenserziehung, Bildung

description: Die Schwerpunkte der vorliegenden Arbeit liegen in den Bereichen post-moderner Friedensansätze, wie beispielsweise energetische und moralische Frieden, des trans-rationalen Friedensansatzes und des demokratischen Friedensansatzes bei dem auch die drei wichtigsten politikwissenschaftlichen Erklärungsmodelle Thema sind. Die Werke der Autoren Carl Schmitt „Der Begriff des Politischen“ und Dolf Sternberger „Begriff des Politischen“ waren und sind fundamental im Bereich Politischer Theorie und Ideengeschichte zu den Themen Krieg und Frieden sowie auch zum Thema Freund und Feind. Eine Untersuchung und ein Vergleich zu Kernaussagen bzw. Kernfragen der Völkerrechtsordnung im Kontext der Thematik Krieg und Frieden, hier vor allem politische Motive und Handlungen, sind wesentliche Inhalte die kontrovers diskutiert werden. Definitionen von Frieden und Krieg und Fridens-ansätze, auch im historischen Kontext, werden fokussiert und behandelt. Hier liegt ein Schwerpunkt auf wissenschaftlich fundierten Fiedensansätzen. Beispielsweise wird Im Bereich „Demokratischer Frieden“ die Theorie in ein normatives Postulat und ein analytisches Forschungsprogramm unterteilt. Hier existieren auch „Demokratische Frieden“ und „Demokratische Kriege“ nebeneinander. Innerhalb der Theorien der internationalen Beziehungen als subsystemischer Ansatz erfolgt die Zuordnung dem Paradigma des Liberalismus. Diese liberalen Ansätze sehen im Unterschied zum klassischen Realismus oder Neorealismus die Ursachen für Frieden und/oder Krieg nicht primär im Bereich der zwischenstaatlichen Ebene, sondern sind auf die innerstaatliche Situation der Konfliktparteien zentriert. Neben diesen Ansätzen ist auch das Thema Friedensforschung eine wesentliche Komponente im Bereich der Politik. In der modernen Friedensforschung sind auch die Themen Friedenserziehung, Friedenspädagogik und Friedenskultur von zunehmender Relevanz. Im Kontrext der Erziehung für eine Kultur des Friedens werden auch Arbeitsfelder im Bereich der Friedenserziehung aufgezeigt. Ausgewählte Inhalte zum Studienzentrum für Frieden und Konfliktlösung in Österreich, mit deren Forschungsschwerpunkten und der jährlich stattfindenden Konferenz „State of Peacebuilding“ und ein Ausblick auf die Friedenserziehung im Schulbereich sowie eine Reflexion runden die gegenständliche Arbeit ab.

description: A análise crítica à problemática de género permite desmontar as falácias do pensamento eurologocêntrico e apontar os estereótipos que a episteme, tacitamente colonial, edificou. Trata-se de questionar, no conceito de género e na dicotomia nele subjacente – masculino/feminino –, a lógica do pensamento ocidental, de matriz binária, e como essa lógica se afigura ser aquela que impera face ao olhar de e sobre o Outro, o colonizado.O que acontece, tanto com os estudos de género, quanto com os estudos pós-coloniais, é eles abrirem novas epistemes e mostrarem, portanto, que a episteme ocidental, nas suas bases disciplinadoras, é reprodutora de estereótipos e de lógicas eurologocêntricas, e, ainda, que as ontologias que constrói são, antes de mais, epistemologias ancoradas historicamente e nos juízos avaliativos da chamada cultura ocidental moderna. A convocação da análise à Chora platónica permitiu sair do pensamento dicotómico e repensar os processos de subjectivação como processos transubjectivos.

description: Synchronisation and stability under periodic oscillatory driving are well-understood, but little is known about the effects of aperiodic driving, despite its abundance in nature. Here, we consider oscillators subject to driving with slowly varying frequency, and investigate both short-term and long-term stability properties. For a phase oscillator, we find that, counter-intuitively, such variation is guaranteed to enlarge the Arnold tongue in parameter space. Using analytical and numerical methods that provide information on time-variable dynamical properties, we find that the growth of the Arnold tongue is specifically due to the growth of a region of intermittent synchronisation where trajectories alternate between short-term stability and short-term neutral stability, giving rise to stability on average. We also present examples of higher-dimensional nonlinear oscillators where a similar stabilisation phenomenon is numerically observed. Our findings help support the case that in general, deterministic non-autonomous perturbation is a very good candidate for stabilising complex dynamics.

description: In the hadronic phase, the dominant configuration of QCD with two flavors of massless quarks is a gas of massless pions. We calculate the bulk viscosity (zeta) using the Boltzmann equation with the kinetic theory generalized to incorporate the trace anomaly. We find that the dimensionless ratio zeta/s, s being the entropy density, is monotonic increasing below T=120 MeV, where chiral perturbation theory is applicable. This, combined with previous results, shows that zeta/s reaches its maximum near the phase transition temperature Tc, while eta/s, eta being the shear viscosity, reaches its minimum near Tc in QCD with massless quarks.

description: Nuclear emulsions are capable of very high position resolution in the detection of ionizing particles. This feature can be exploited to directly resolve the micrometric-scale fringe pattern produced by a matter-wave interferometer for low energy positrons (in the 10-20 keV range). We have tested the performance of emulsion films in this specific scenario. Exploiting silicon nitride diffraction gratings as absorption masks, we produced periodic patterns with features comparable to the expected interferometer signal. Test samples with periodicities of 6, 7 and 20 μm were exposed to the positron beam, and the patterns clearly reconstructed. Our results support the feasibility of matter-wave interferometry experiments with positrons.

description: We generalize the definition of strong positive partial transpose (SPPT) to the multipartite system. The tripartite case was first considered by X.-Y. Yu and H. Zhao [ Int. J. Theor. Phys.,54, 292, (2015)]. In this extension, unfortunately, desired properties such as the PPT of SPPT states the separability of super and pure SPPT states are not preserved. In contrast, this paper provides an alternative generalization to multipartite cases with these properties preserved. We also provide sufficient conditions for the separability of SPPT states.

Only area in T. crassaformis still contained a small amount of autocorrelation in the first differences time series. However, comparison of two Generalized Least Squares models with and without autocorrelation (by setting the continuous auto-correlation parameter phi=0.3 and phi=0.1, which converges to 0 under maximum likelihood, respectively) show lower AIC values for the model without autocorrelation, implying that the model with temporal autocorrelation is actually a poorer fit to the data than that without. S5: ΔAIC values showing the added relative importance of each environmental parameter or combination of parameters to the total model.

description: The highly industrialized and densely populated city of Tarapur provides ideal conditions for the study of the effects of urban stresses on plants. The foliar surface of plants is an important receptor of atmospheric pollutants hence it is very crucial to select suitable plant species for urban environment. Tithonia diversifolia a member of Asteraceae was exposed to five different sites during the dry season of 2011. The transplants were exposed for thirty days. The above grounds phytomass dry weight, shoot length, total chlorophyll content and dust fall were recorded. The readings were compared with a control which was a relatively clean area. The decrease in all the parameters was observed when compared to control. There was a marked seasonal variation in all the parameters. Shoot length and chlorophyll content are more reliable parameters for air quality indication and in identifying Tithonia diversifolia as important indicator species. Urban air quality affects the health of humans, animals, and plants equally. Hence it becomes necessary to monitor the air quality for taking the abatement measures and understanding the effect of air pollutants on living organisms.
