description: In the process of sustainability and especially electricity transition, the local and regional levels gain a new importance. Both social movements as well as governments from different levels (state, federal) are mobilizing and/or addressing local actors. The way this has been done and the capacities for local actors to have a say in the way transition processes do unfold, however, has changed significantly over the last decades in Germany. The paper will use the example of wind energy projects to analyze how multilevel governance arrangements have changed over time. The main thesis will be that the available repertoires of activities for local actors have become increasingly limited due to increasing policy management activities by state and federal governments. Especially the creation of artificial markets and auctioning devices have severely limited the scope of action for local actors. The article will reconstruct the changes in the multi-level governance structure and assess the effects on the development of wind energy by studying in detail two cases.
description: Im Zuge von Bemühungen um eine möglichst nachhaltige Gestaltung der Gesellschaft, wie insbesondere der Energiewende, kommt der lokalen und regionalen Ebene eine wichtige Bedeutung zu. Sowohl soziale Bewegungen als auch Regierungen auf verschiedenen Ebenen (Land, Bund) mobilisieren und/oder wenden sich an lokale Akteure. Die Art und Weise, wie dies geschieht, und die Möglichkeiten lokaler Akteure, den Übergangsprozess mitzugestalten, haben sich in den letzten Jahrzehnten in Deutschland jedoch stark verändert. Am Beispiel von Windenergieprojekten analysieren wir, wie sich Governance-Arrangements auf mehreren Ebenen im Laufe der Zeit verändert haben. Die Hauptthese ist, dass die Handlungsmöglichkeiten lokaler Akteure durch die zunehmende politische Steuerung durch Bund und Länder zunehmend eingeschränkt werden. Vor allem die Schaffung künstlicher Märkte und Versteigerungen haben den Handlungsspielraum der lokalen Akteure zunehmend begrenzt. Der Artikel rekonstruiert die Veränderungen in der Multi-Level-Governance-Struktur und untersucht die Auswirkungen auf die Entwicklung der Windenergie anhand von zwei Fallbeispielen.

description: We consider the case of a deformable material interface between two immiscible moving media, both of them being magnetiable. The time dependence of the metric at the interface introduces a non linear term, proportional to the mean curvature, in the surface dynamical equations of mass momentum and angular momentum. We take into account the effects of that term also in the singular magnetic and electric fields inside the interface which lead to the existence of currents and charges densities through the interface, from the derivation of the Maxwell equations inside both bulks and the interface. Also, we give the expression for the entropy production and of the different thermo-dynamical fluxes. Our results enlarge previous results from other theories where the specific role of the time dependent surface metric was insufficiently stressed.

description: Cascade models on networks have been used extensively to study cascade failure in complex systems. However, most current models consider failure caused by node damage and neglect the possibility of link damage, which is relevant to transportation, social dynamics, biology, and medicine. In an attempt to generalize conventional cascade models to link damage, we propose a link cascade model based on the standard independent cascade model, which is then solved via both numerical simulation and analytic approximation. We find that the probability that a node loses all its links due to link damage exhibits a minimum as a function of node degree, indicating that there exists an optimal degree for a node to be most resistant to link damage. We apply our model to investigate the sign distribution in a real-world signed social network and find that such optimal degree does exist in real-world dataset.

description: A summary of the results of several recent studies of charm mixing is presented. A number of different methods were used, including the measurement of lifetime ratios for final states of different CP, time dependence of wrong-sign hadronic decays, fits to time-dependent Dalitz plots, and searches for wrong-sign semi-leptonic decays. Taken together, they suggest mixing is of order 1%. The status of searches for indirect CP violation is also reported.

An Unfinished Revolution: A Historically Informed Picture of J.L. Austin’s Philosophy
Creators: name: Moscaritolo, Alessandro Ramon
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: J.L. Austin was the de facto leader of so-called ordinary language philosophy, the very heterogeneous philosophical movement that came into prominence at Oxford after the Second World War. But after his premature death in 1960, mainstream Anglo-American philosophy quickly came to view Austin’s work as obsolete. My dissertation challenges this view; it does so by reading Austin’s works against the historical context that accords them their true significance. In chapter II, I argue that Austin’s philosophy is part of a subversive movement founded by John Cook Wilson, a now-forgotten late-19th century anti-idealist revolutionary. This proposal challenges the widespread prejudice that Austin’s philosophy is an offshoot of Wittgenstein’s. I build on these results to engage in a historically informed reading of Austin’s ideas on knowledge and language. In chapter III, I put forth an alternative reading of “Other Minds,” Austin’s only essay in general epistemology. I argue that this essay has been systematically misunderstood because key components of Austin’s philosophical method and vision have been misunderstood. In chapter IV, I examine Austin’s works on language as a topic of interest in its own right, with a special emphasis on How to Do Things with Words. After showing that this work is in fact an elaboration of ideas Austin took up from Cook Wilson and H.A. Prichard (Austin’s teacher), I argue against the re-interpretation of Austin’s views on language put forth by Grice, Searle, and Derrida. Finally, I argue that in How to Do Things with Words, Austin gestures at a subversive model of positive theorizing.

description: The combination of gas-phase oxygen abundances and stellar metallicities can provide us with unique insights into the metal enrichment histories of galaxies. In this work, we compare the stellar and gas-phase metallicities measured within a 1$R_{e}$ aperture for a representative sample of 472 star-forming galaxies extracted from the SAMI Galaxy Survey. We confirm that the stellar and interstellar medium (ISM) metallicities are strongly correlated, with scatter $\sim$3 times smaller than that found in previous works, and that integrated stellar populations are generally more metal-poor than the ISM, especially in low-mass galaxies. The ratio between the two metallicities strongly correlates with several integrated galaxy properties including stellar mass, specific star formation rate, and a gravitational potential proxy. However, we show that these trends are primarily a consequence of: (a) the different star formation and metal enrichment histories of the galaxies, and (b) the fact that while stellar metallicities trace primarily iron enrichment, gas-phase metallicity indicators are calibrated to the enrichment of oxygen in the ISM. Indeed, once both metallicities are converted to the same `element base' all of our trends become significantly weaker. Interestingly, the ratio of gas to stellar metallicity is always below the value expected for a simple closed-box model, which requires that outflows and inflows play an important role in the enrichment history across our entire stellar mass range. This work highlights the complex interplay between stellar and gas-phase metallicities and shows how care must be taken in comparing them to constrain models of galaxy formation and evolution.

Mathematical model of the SL/RN direct reduction process
Creators: name: Venkateswaran, V.
Publisher: name: University of British Columbia
Year: 2010

description: A mathematical model has been developed to predict the operating behaviour of an SL/RN direct reduction kiln from a knowledge of the main process variables. The model is based on steady state principles and is capable of quantitatively describing the complex chemical reactions in the kiln such as reduction, Boudouard reaction, coal volatilization and combustion in the freeboard together with the mass and heat flows. Output from the model is in the form of axial profiles of gas, solids and wall temperatures, and concentrations in both the gas and the solid phases. Results from the model are in good agreement with measurements made on the 100 ton per day pilot kiln at the Steel Company of Canada. The influence of important process variables such as the type of coal, ore, degree of reduction, throughput etc. has been examined and predictions made regarding the operation of large commercial SL/RN kilns for sponge iron production.

description: Future activity anticipation is a challenging problem in egocentric vision. As a standard future activity anticipation paradigm, recursive sequence prediction suffers from the accumulation of errors. To address this problem, we propose a simple and effective Self-Regulated Learning framework, which aims to regulate the intermediate representation consecutively to produce representation that (a) emphasizes the novel information in the frame of the current time-stamp in contrast to previously observed content, and (b) reflects its correlation with previously observed frames. The former is achieved by minimizing a contrastive loss, and the latter can be achieved by a dynamic reweighing mechanism to attend to informative frames in the observed content with a similarity comparison between feature of the current frame and observed frames. The learned final video representation can be further enhanced by multi-task learning which performs joint feature learning on the target activity labels and the automatically detected action and object class tokens. SRL sharply outperforms existing state-of-the-art in most cases on two egocentric video datasets and two third-person video datasets. Its effectiveness is also verified by the experimental fact that the action and object concepts that support the activity semantics can be accurately identified.
Novel two photon absorbers: evaluation of photophysical properties in view of biomedical applications

description: This thesis was focused on the investigation of the linear optical properties of novel two photon absorbers for biomedical applications. Substituted imidazole and imidazopyridine derivatives, and organic dendrimers were studied as potential fluorophores for two photon bioimaging. The results obtained showed superior luminescence properties for sulphonamido imidazole derivatives compared to other substituted imidazoles. Imidazo[1,2-a]pyridines exhibited an important dependence on the substitution pattern of their luminescence properties. Substitution at imidazole ring led to a higher fluorescence yield than the substitution at the pyridine one. Bis-imidazo[1,2-a]pyridines of Donor-Acceptor-Donor type were examined. Bis-imidazo[1,2-a]pyridines dimerized at C3 position had better luminescence properties than those dimerized at C5, displaying high emission yields and important 2PA cross sections. Phosphazene-based dendrimers with fluorene branches and cationic charges on the periphery were also examined. Due to aggregation phenomena in polar solvents, the dendrimers registered a significant loss of luminescence with respect to fluorene chromophore model. An improved design of more rigid chromophores yields enhanced luminescence properties which, connected to large 2PA cross-sections, make this compounds valuable as fluorophores in bioimaging.
The photophysical study of several ketocoumarine initiators, designed for the fabrication of small dimension prostheses by two photon polymerization (2PP) was carried out. The compounds showed low emission yields, indicative of a high population of the triplet excited state, which is the active state in producing the reactive species. Their efficiency in 2PP was proved by fabrication of microstructures and their biocompatibility was tested in the collaborator’s laboratory.
In the frame of the 2PA photorelease of drugs, three fluorene-based dyads have been investigated. They were designed to release the gamma-aminobutyric acid via two photon induced electron transfer. The experimental data in polar solvents showed a fast electron transfer followed by an almost equally fast back electron transfer process, which indicate a poor optimization of the system.
Smooth tensionful higher-codimensional brane worlds with bulk and brane form fields

description: Completely regular tensionful codimension-n brane world solutions are discussed, where the core of the brane is chosen to be a thin codimension-(n-1) shell in an infinite volume flat bulk, and an Einstein-Hilbert term localized on the brane is included (Dvali-Gabadadze-Porrati models). In order to support such localized sources we enrich the vacuum structure of the brane by the inclusion of localized form fields. We find that phenomenological constraints on the size of the internal core seem to impose an upper bound to the brane tension. Finite transverse-volume smooth solutions are also discussed.

Design and Optimization of Nanoformulations for Stability and Sustained Release of Therapeutic Compounds

Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Due to the complexity of physiological conditions inside the human body, therapeutic compounds often face challenges such as short half-life in plasma, fast enzymatic metabolism and degradation. Nanocarriers such as liposomes and polymeric nanoparticles offer solutions to improve the stability and sustain the release of therapeutic compounds. However, the development of such vehicles often requires careful optimization. We demonstrated that by using X-ray techniques integrated with the Langmuir trough, the liposomal development process can be shortened significantly through the understanding of the molecular interaction between our prodrug 5-FCPal, a capecitabine analogue, with our model lipids and the effects of 5-FCPal on the lipid packing structure at the air-liquid interface. Additionally, the X-ray techniques can be used as a new platform to predict the drug loading in liposomes by increasing the molar fraction of the prodrug in the monolayer and observing the changes in molecular interaction. It was revealed that 5-FCPal interacted strongly with cationic lipids through electrostatic interaction of the head groups and caused the molecular packing to be tighter while the prodrug exhibited weak interaction with neutral and anionic lipids. Proof-of-concept nanoformulations were prepared and found that cationic lipids were able to form 100 nm vesicles while neutral lipids formed large aggregates with 5-FCPal. Utilizing a unique flash nanoprecipitation (FNP) process, polymeric particles were optimized to sustain the release of pazopanib for the treatment of osteoarthritis (OA). The results showed that the release of pazopanib strongly depended on the degradation rate of the polymer matrix and pH conditions. In vivo efficacy evaluation found that after single injection, the pain reduction effect lasted up to 16 weeks in mice with partial medial meniscectomy (PMM)-induced knee. FNP was also optimized to produce PLGA polymeric nanoparticles encapsulating emricasan, a peptide compound with poor pharmacokinetics property. The nanoparticles stability in aqueous condition was tracked for 6 hours. Our results indicated that the nanoparticles were more stable with shorter sonication time and lower concentration of trehalose (added as cryoprotectant). These results lay the important groundwork for future direction of designing stable nanoparticles systems to improve emricasan pharmacokinetics and enhance its cancer treatment property.

description: Aviation's fossil fuel emissions contribute to global warming. The production and disposal of the materials used in aircrafts too. The current metallic alloys present in the hot section of engines pose constraints in terms of temperature, pressure and weight that restrain the performance of the aircrafts. Also, these alloys are produced using rare, depleting resources, and polluting processes. In this paper, we hypothesize the use of bioinspired nacre-like alumina (NLA), a ceramic material that exhibits unusual toughness, and evaluate its potential as a replacement for superalloys in aircraft's engines. Comparing the performance of Ni superalloys and NLA in terms of properties, engine performance, and life cycle sustainability, we find NLA a promising alternative although progress has to be made with regards to its reliability, shaping, repair, and governance of the production process.

description: Numerous variants of SARS-CoV-2 with increased transmissibility have emerged over the course of the pandemic. Potential explanations for the increased transmissibility of these variants include increased shedding from infected individuals, increased environmental stability, and/or a lower infectious dose. Upon exhalation of a respiratory particle into the environment, water present in the particle is rapidly lost through evaporation, resulting in a decrease in particle size. The aim of the present study was to compare the losses of infectivity of different isolates of SARS-CoV-2 during the rapid evaporation of aerosol particles that occurs immediately post-generation to assess if there are differences suggestive of increased survival, and ultimately greater transmissibility, for more recent variants. Losses of infectivity of several isolates of SARS-CoV-2 suspended in viral culture media were assessed following aerosolization and evaporation in a flowing chamber. The results demonstrate that losses of infectivity measured post-evaporation were similar for three different isolates of SARS-CoV-2, including isolates from the more recent Delta and Omicron lineages. The average loss in infectivity across all three isolates was 61 ± 15% (−0.46 ± 0.17 log10 TCID50/L-air) at a relative humidity <30%. These results, together with those from several previous studies, suggest that it is unlikely that an increase in environmental stability contributes to the observed increases in transmissibility observed with more recent variants of SARS-CoV-2.

description: In this talk we investigate the symmetry under E10 of Romans' massive type IIA supergravity. We show that the dynamics of a spinning particle in a non-linear sigma model on the coset space E10/K(E10) reproduces the bosonic and fermionic dynamics of massive IIA supergravity, in the standard truncation. In particular, we identify Romans' mass with a generator of E10 that is beyond the realm of the generators of E10 considered in the eleven-dimensional analysis, but using the same, underformed sigma model. As a consequence, this work provides a dynamical unification of the massless and massive versions of type IIA supergravitiy inside E10.

description: Atomic ionised regions with strong continuum emission are often associated with regions of high-mass star formation and low-frequency (<2GHz) observations of these regions are needed to help build star formation models. The region toward the Vela Supernova Remnant is particularly interesting as it is a complex structure of recent supernova explosions and molecular clouds containing a number of HII regions that are not well characterised. We searched publicly available catalogues for HII regions, both candidate and identified, which also have low-frequency emission. In the area of ~400 square degrees toward the Vela Supernova remnant, we found 10 such HII regions, some of which have multiple components in catalogues. In this work we use data from the Australian Square Kilometre Array Pathfinder and previously unpublished data from the Murchison Widefield Array and the Australian Telescope Compact Array to analyse these sources. The high-mass star forming region RCW 38, with observations specifically targeted on the source, is used as a pilot study to demonstrate how low-frequency, wide-field continuum observations can identify and study HII regions in our Galaxy. For the 9 other HII regions, we discuss their properties; including information about which clouds are interacting, their ages, whether they are dominated by infrared or optical H$α$ lines, distances, ionising photon flux, and upper limits on the infrared luminosity. In future work, these 9 regions will be analysed in more detail, similar to the result for RCW 38 presented here.

The angular momentum of two collided rarefied preplanetesimals and the formation of binaries

Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: This paper studies the mean angular momentum associated with the collision of two celestial objects in the earliest stages of planet formation. Of primary concern is the scenario of two rarefied preplanetesimals (RPPs) in circular heliocentric orbits. The theoretical results are used to develop models of binary or multiple system formation from RPPs, and explain the observation that a greater fraction of binaries originated farther from the Sun. At the stage of RPPs, small-body satellites can form in two ways: a merger between RPPs can have two centers of contraction, or the formation of satellites from a disc around the primary or the secondary. Formation of the disc can be caused by that the angular momentum of the RPP formed by the merger is greater than the critical angular momentum for a solid body. One or several satellites of the primary (moving mainly in low-eccentricity orbits) can be formed from this disc at any separation less than the Hill radius. The first scenario can explain a system such as 2001 QW322 where the two components have similar masses but are separated by a great distance. In general, any values for the eccentricity and inclination of the mutual orbit are possible. Among discovered binaries, the observed angular momenta are smaller than the typical angular momenta expected for identical RPPs having the same total mass as the discovered binary and encountering each other in circular heliocentric orbits. This suggests that the population of RPPs underwent some contraction before mergers became common.

description: Aims: I investigate the gravitational binding of a nearby common proper motion system in the young Castor moving group (tau ~ 200 Ma), formed by the bright quadruple star alpha Lib (Zubenelgenubi) and the young solar analog KU Lib. The system has an exceptionally wide angular separation, of about 2.6 deg, which corresponds to a projected physical separation of about 1.0 pc. Methods: I compile basic information of the system and compare its binding energy with those of other weakly bound systems in the field, and study the physical separations of resolved multiple systems in Castor. Results: KU Lib has roughly the same proper motion, parallactic distance, radial velocity, and metallicity than the young hierarchical quadruple system alpha Lib. Besides, KU Lib also displays youth features. The resemblance between these basic parameters and the relatively large estimated binding energy point out that the five stars are gravitationally bound. KU Lib and alpha Lib constitute the widest known multiple system at all mass domains, and likely represent the most extreme example of young wide binaries on the point of being disrupted. Besides, I make a comprehensive compilation of star candidates in Castor, including new ones.

description: Being able to safely distinguish astrophysical from potential dark matter (DM) annihilation signals is of utmost importance for indirect DM searches. To this end, one has to rely on distinctive -- and unique -- spectral signatures to look for. Internal bremsstrahlung (IB), unavoidable in the presence of charged annihilation products, provides such a signature. In fact, as it generically dominates the gamma-ray spectrum expected from DM annihilations, at high energies, it may well turn out to be more important for indirect DM searches than the traditionally looked-for line signals. As illustrated in some detail, the observation of IB signatures would even allow to distinguish between different DM candidates or to constrain significantly the parameter space of, e.g., neutralino DM. The gamma-ray contributions reported here are therefore of great interest for the already launched Fermi/GLAST satellite and the upcoming new generation of Air Cherenkov Telescope systems like CTA -- which are most sensitive at the high energies where these effects are particularly important. Finally, radiative corrections may even significantly alter the positron spectrum from DM annihilations; an intriguing positron excess recently found by the PAMELA satellite might turn out to be an indication of the peculiar spectral signature expected in that case.

Revisiting a Paradox of Increased Cannibalism Among Juvenile Wolf Spiders with an Individual-Based Model

description: To resolve an observed paradox by Wagner & Wise (1996) where similar or increased rates of cannibalism were observed among juvenile wolf spiders (Lycosidae) despite an increase in habitat complexity and the presence of alternative prey, I developed a series of individual-based models within the modeling environment NetLogo to test several hypotheses that could potentially replicate the phenomenon. I calibrated my models with real-world spider data and scaled the dimensions of the simulations to match that of Wagner & Wise’s 1996 mesocosm experiment (0.35 m2). Instead of replicating their 2x2 factorial design, however, I modeled habitat complexity along a gradient of increasing leaf litter cover which captured potential non-linearities that may have been missed along this gradient. Failing to reproduce the paradox with the first set of mechanisms I tested, I adjusted the model to incorporate an additional range of cannibalistic propensities within the modeled spider population. Some spiders would starve before attacking conspecifics, others would attack conspecifics only if hungry, and another group would readily attack conspecifics without any physiological constraints. This trait was also plastic, meaning spiders which were normally reluctant to engage in cannibalism shifted their behavior to become more aggressive while within leaf litter. Following these adjustments, I successfully demonstrated multiple sets of circumstances under which the paradox could be replicated, namely when the spider population was initialized to be heterogenous regarding their affinity towards cannibalism, and when leaf litter induced a behavioral shift towards the most aggressive cannibalistic morph. Although my model may not replicate the exact set of circumstances that produced the original paradox, this research revealed several in which it could, increasing the likelihood that the pattern Wagner & Wise observed in their mesocosm study is a naturally occurring phenomenon. Additionally, because of NetLogo's ease of use in exploring speculative hypotheses, this research provides a scaffold for alternative theories to be proposed and tested. If future empirical studies can successfully demonstrate these patterns, then this might shift the paradigm of how ecologists envision “highly cannibalistic” species, leading population and community models to consider incorporating an innate propensity to cannibalize within their framework.

description: Let $K=k(C)$ be the function field of a curve over a field $k$ and let $X$ be a smooth, projective, separably rationally connected $K$-variety with $X(K)\neq\emptyset$. Under the assumption that $X$ admits a smooth projective model $π: \mathcal{X}\to C$, we prove the following weak approximation results: (1) if $k$ is a large field, then $X(K)$ is Zariski dense; (2) if $k$ is an infinite algebraic extension of a finite field, then $X$ satisfies weak approximation at places of good reduction; (3) if $k$ is a nonarchimedean local field and $R$-equivalence is trivial on one of the fibers $\mathcal{X}_p$ over points of good reduction, then there is a Zariski dense subset $W\subseteq C(k)$ such that $X$ satisfies weak approximation at places in $W$. As applications of the methods, we also obtain the following results over a finite field $k$: (4) if $|k|>10$, then for a smooth cubic hypersurface $X/K$, the specialization map $X(K)\longrightarrow \prod_{p\in P}\mathcal{X}_p(κ(p))$ at finitely many points of good reduction is surjective; (5) if $\mathrm{char} k\neq 2, 3$ and $|k|>47$, then a smooth cubic surface $X$ over $K$ satisfies weak approximation at any given place of good reduction.

Comment on "Does Gluons Carry Half of the Nucleon Momentum?" by X. S. Chen et. al. (PRL103, 062001 (2009))

description: The authors claim to have found a "proper", "gauge-invariant" definition of a charged-particle's momentum in gauge theory, which is more "superior" than the textbook version. I show that their result arises from a misunderstanding of gauge symmetry by generalizing the Coulomb gauge result indiscriminately and is not physical.
Femtosecond Laser Desorption Postionization Mass Spectrometry Imaging of Geological Samples

description: Ultrashort pulses from femtosecond (fs) lasers can be used to ablate any material regardless of the target’s optical properties. Another important aspect of fs laser pulses is that, while ablating material from a sample surface, they do minimal or no damage to the underlying material. Single-photon ionization is a universal ionization mechanism of molecules that is less constrained by molecules’ structural and electronic properties. A newly designed time-of-flight mass analyzer has been built and implemented on the custom-built laser desorption postionization (LDPI) mass spectrometer in the Hanley group, replacing the old reflectron time-of-flight mass analyzer with a new time-of-flight referred to as a right angle ion mirror prism (RAIMP). A fluorine excimer laser was also added as a photoionization laser. The 7.9 eV fs-LDPI mass spectrometry utilizes 800 nm, <100 fs desorption pulses combined with 157 nm, 7.9 eV photon energies from the fluorine excimer laser for single-photon ionization. The 7.9 eV fs-LDPI technique can be used to analyze various samples, including test mixtures, drug compounds, and geological samples. The performance of the new LDPI RAIMP-TOF mass spectrometer is evaluated and documented regarding mass resolution and accuracy. Three drug compounds that show low ionization efficiencies in secondary ion mass spectrometry have been successfully detected and analyzed. The ability of fs-LDPI mass spectrometry on analyzing geological samples is demonstrated and discussed in terms of performing targeted analysis, removing surface contaminants, and excavating into the sample to uncover organic components and hence biomarkers.

description: Let{N(t), -T<t0, assumed integrable on [-T,T]. The optimal linear estimator, λ[sub L], of the intensity function is considered in this thesis. Chapter 1 discusses λ[sub L] as a function of h(t;s), which is Lthe unique solution of the Fredholm integral equation of the second kind, m(s)h[sub t](s) + /[sup b/ sub a]K(s;u)h[sub t](u)du = K(t;s), a<s<b. Chapters 2 and 3 are respectively devoted to a discussion of some of the exact and approximate methods for solving the above integral equation. To illustrate the use of the techniques devised, three numerical examples are treated. Chapter 4 deals with data on oilwell discoveries in Alberta, Canada. Finally, in Chapter 5, the model is applied to data on traffic counts on the Lions Gate Bridge, Vancouver, and to data on coal-mining disasters in Great Britain. Computer programs and numerous diagrams are also presented.

description: This article introduces REAS (Rutgers Electrostatic Active Sampler), a new active bioaerosol sampler using permanently polarized ferroelectric film (e.g., PVDF) to capture charge-carrying bioaerosol particles. While REAS operates on an electrostatic collection principle, due to its unique materials and design, it does not require external power to charge incoming particles or to create an electrostatic collection field. The sampler consists of a polarized film wound in a spiral configuration with oppositely polarized film sides positioned 2.25 mm apart. The film and its holder are inserted into a 3D-printed housing cylinder to connect to a pump. The device has an open channel design, creating virtually no pressure drop, which allows for longer sampling times on the same battery charge compared to filter samplers. When REAS was tested in different field environments, the physical collection efficiency ranged from 19 ± 2% in a laboratory environment at 1 L/min to 41 ± 0.1% in residence at 0.1 L/min. When REAS was used to capture culturable bacteria and fungi over a 24-hr period, the concentrations determined by REAS were not different from those determined by an Institute of Medicine sampler (IOM, SKC, Inc.). The concentrations determined by both samplers were lower than those measured by a SAS Super 180 Sampler (SAS, Bioscience International), except for outdoor fungi. However, the SAS was used as a grab sampler to avoid overloading or desiccating the plates, while both REAS and IOM continuously sampled for 24 hrs. Further studies will explore improvements to the REAS sample elution protocols. Copyright © 2022 American Association for Aerosol Research
