description: Toilet flushing is known to generate and disperse bioaerosols which can contaminate surfaces in the washroom and increase the risk of infections through contact with the contaminated surfaces or inhalation of these bioaerosols. Whilst this phenomenon is well known for gravity toilets, vacuum toilets have been hypothesized not to generate bioaerosols and have been tagged as more sanitary compared to the gravity toilet. This study investigates whether a vacuum toilet produces bioaerosols and how the bioaerosols and particle concentrations of a vacuum and a gravity toilet differ from each other. The study further looks into the reasons and behaviour of the measured concentrations based on the main difference between the toilets - their flushing mechanism. Experiments were conducted in a warehouse-office building using two identical toilet cubicles with dimensions of 1.5 meters by 1.17 meters which were constructed for the purposes of this study. 12 experimental conditions this were framed around two main toilet-use scenarios; using the toilet during an incidence of diarrhea and using the toilet when there was no diarrhea (faecal matter of solid consistency). Faecal matter was not used in this study; rather, Escherichia coli bacteria, an indicator organism for faecal contamination on surfaces and in toilet water was used in seeding the toilet bowls to represent the experimental conditions in the study. The bioaerosol concentrations in this study were measured according to the ACGIH and ASTM standards. Particle concentrations were measured using an optical particle counter. Based on the results of this study, it can be concluded that, gravity toilets produce bioaerosols via visible splashes or overspray when faecal matter of loose or solid consistency is flushed with the lid open, but a vacuum toilet would not produce bioaerosols or visible splashes under the same conditions
The Star-Forming Histories of the Nucleus, Bulge, and Inner Disk of NGC 5102: Clues to the Evolution of a Nearby Lenticular Galaxy

description: Long slit spectra recorded with GMOS on Gemini South are used to examine the star-forming history of the lenticular galaxy NGC 5102. Structural and supplemental photometric information are obtained from archival Spitzer [3.6] images. Comparisons with model spectra point to luminosity-weighted metallicities that are consistent with the colors of resolved red giant branch stars in the disk. The nucleus has a luminosity-weighted age at visible wavelengths of ~1 Gyr, and the integrated light is dominated by stars that formed over a time period of only a few hundred Myr. For comparison, the luminosity-weighted ages of the bulge and disk are ~2 Gyr and ~10 Gyr, respectively. The g'-[3.6] colors of the nucleus and bulge are consistent with the spectroscopically-based ages. In contrast to the nucleus, models that assume star-forming activity spanning many Gyr provide a better match to the spectra of the bulge and disk than simple stellar population models. Isophotes in the bulge have a disky shape, hinting that the bulge was assembled from material with significant rotational support. The star-forming histories of the bulge and disk are consistent with the bulge forming from the collapse of a long-lived bar, and it is suggested that the progenitor of NGC 5102 was a barred disk galaxy that morphed into a lenticular galaxy through the buckling of its bar.

Quantitative Approximation of the Probability Distribution of a Markov Process by Formal Abstractions

Subjects: subject: Logic in Computer Science (cs.LO)

description: The goal of this work is to formally abstract a Markov process evolving in discrete time over a general state space as a finite-state Markov chain, with the objective of precisely approximating its state probability distribution in time, which allows for its approximate, faster computation by that of the Markov chain. The approach is based on formal abstractions and employs an arbitrary finite partition of the state space of the Markov process, and the computation of average transition probabilities between partition sets. The abstraction technique is formal, in that it comes with guarantees on the introduced approximation that depend on the diameters of the partitions: as such, they can be tuned at will. Further in the case of Markov processes with unbounded state spaces, a procedure for precisely truncating the state space within a compact set is provided, together with an error bound that depends on the asymptotic properties of the transition kernel of the original process. The overall abstraction algorithm, which practically hinges on piecewise constant approximations of the density functions of the Markov process, is extended to higher-order function approximations: these can lead to improved error bounds and associated lower computational requirements. The approach is practically tested to compute probabilistic invariance of the Markov process under study, and is compared to a known alternative approach from the literature.

Increasing Vocational Information Seeking Behaviors of High School Students
Creators: name: Redmond, Ronald E.
Publisher: name: Digital Repository at the University of Maryland
Year: 1972

description: This study was an outgrowth of previous research which investigated reinforcement techniques used to increase the frequency of vocational information seeking behaviors (VISB). Based on the Larramore (1971) finding that subjects (Ss) intended but did not always carry out the suggested vocational information seeking behaviors (VISB), it became apparent that additional research was required to increase the actual performance of certain career seeking behaviors. This research was designed to evaluate the reinforcing effects of the Self-Directed Search (SDS, Holland, 1970) and contingency contracts on the frequency of VISB performed by high school Ss. It was assumed that the administration of the Self-Directed Search (SDS) followed by a contingency contract would increase the performance of a greater number of VISB than the administration of the SDS alone.
Field-regulated force by grafted polyelectrolytes

description: Generation of mechanical force regulated by external electric field is studied both theoretically and by molecular dynamics (MD) simulations. The force arises in deformable bodies linked to the free end of a grafted polyelectrolyte chain which is exposed to electric field that favours its adsorption. We consider a few target bodies with different force-deformation relations including (i) linear and (ii) cubic dependences as well as (iii) Hertzian-like force. Such force-deformation relations mimic the behaviour of (i) coiled and (ii) stretched polymer chains, respectively, or (iii) that of a squeezed colloidal particle. The magnitude of the arising force varies over a wide interval although the electric field alters within a relatively narrow range only. The predictions of our theory agree quantitatively well with the results of numerical simulations. Both cases of zero and finite electrical current are investigated and we do not obtain substantial differences in the force generated. The phenomenon studied could possibly be utilised to design, e.g., vice-like devices to fix nano-sized objects.

description: A single crystal of the Co2+ based pyrochlore NaCaCo2F7 was studied by inelastic neutron scattering. This frustrated magnet with quenched exchange disorder remains in a strongly correlated paramagnetic state down to one 60th of the Curie-Weiss temperature. Below T_f = 2.4 K, diffuse elastic scattering develops and comprises 30 +/- 10% of the total magnetic scattering, as expected for J_{eff} = 1/2 moments frozen on a time scale that exceeds \hbar/δE=3.8 ps. The diffuse scattering is consistent with short range XY antiferromagnetism with a correlation length of 16 Å. The momentum (Q) dependence of the inelastic intensity indicates relaxing XY-like antiferromagnetic clusters at energies below ~ 5.5 meV, and collinear antiferromagnetic fluctuations above this energy. The relevant XY configurations form a continuous manifold of symmetry-related states. Contrary to well-known models that produce this continuous manifold, order-by-disorder does not select an ordered state in NaCaCo2F7 despite evidence for weak (~12 %) exchange disorder. Instead, NaCaCo2F7 freezes into short range ordered clusters that span this manifold.

description: Resilience is a word that has been used a lot in the recent past and particularly in policies. The policies call for resilient infrastructure. But what exactly does resilient infrastructure mean? How is resilience defined and operationalised in the water sector? This research examined all the above questions. It used a case study approach to determine how resilient a water service provider’s infrastructure is; that is Severn Trent. It also examined the role the policies played in making their infrastructure and services resilient. Data was collected through policy review and document analysis of Severn Trent’s reports. The results indicated that policies and guidelines had similar approaches to resilience. Severn Trent’s approach was informed by the policies therefore they operationalised resilience the same way the polices did. However, Severn Trent description of resilience varied from one document to another and they did not have a definite definition. Most of the policies did not adequately represent the adaptability characteristic of resilience and this was translated onto Severn Trent. Adaptability was only mentioned with reference to climate change. Even though the utility had made progress towards achieving resilience, it still has a long way to go towards ensuring that their services are resilient in the face of future challenges. The research also showed that there was also room for the policies to grow as they play a key role in enhancing resilience in the sector.

description: The lifetime and utilization of a nuclear fusion reactor like ITER depends strongly on its capabilities to mitigate damage during disruptions. While shattered pellet injection (SPI) was chosen as the baseline mitigation method for ITER, the exact relation of pellet injection parameters and the resulting fragment distributions is not yet clear. This knowledge is of paramount importance for optimizing the impurity deposition and disruption mitigation efficiency. In this thesis, I present fragmentation analysis of 170 SPI pellets, with the focus on the produced fragment sizes as a function of normal impact velocity. The experiments were carried out at the Max Planck-Institute for Plasma Physics (IPP) in Garching, Germany, using the shattered pellet injection system that is now installed on the ASDEX Upgrade tokamak. Comparisons with a theoretical fragmentation model (Parks 2016) show that the model underestimates the amount of fragments below 0.9 mm in diameter. Also, statistical parameters such as the mean fragment size and the standard deviation of fragment size seem to scale exponentially in the experiment and linearly in the model. Furthermore, we found that the fragmentation induced by circular shattering geometries is less reproducible than for rectangular geometries, which might be relevant for design choices in future mitigation systems.

description: The effect of solute hydrogen on the stability of vacancy clusters in hexagonal closed packed zirconium is investigated with an ab initio approach, including contributions of H vibrations. Atomistic simulations within the density functional theory evidence a strong binding of H to small vacancy clusters. The hydrogen effect on large vacancy loops is modeled through its interaction with the stacking faults. A thermodynamic modeling of H segregation on the various faults, relying on ab initio binding energies, shows that these faults are enriched in H, leading to a decrease of the stacking fault energies. This is consistent with the trapping of H by vacancy loops observed experimentally. The stronger trapping, and thus the stronger stabilization, is obtained for vacancy loops lying in the basal planes, i.e. the loops responsible for the breakaway growth observed under high irradiation dose.

description: Globally, the implications of climate change and rapid urbanisation are a growing concern for the future of water resource management. African cities are places with significant water security risk, rapid urbanisation and multiple spatial and temporal scales (UN-WWAP, 2009). Identifying these risks provides insights into where resilience is required, which allows for informed adaptation decisions. Water managers are accustomed to changing circumstances and adapting to them; however, uncertainties associated with climate and socio-economic changes create an additional layer of complexity. Decision-support tools used for the evaluation and management of water resources should reflect the potential impacts of these changes.

description: The article deals with the musical training of the Benedictine nuns at Staniatki Abbey as witnessed by 18th-century sources Music was definitely a substantial component of the life of Benedictine nuns in early modern times With reference to the Staniatki Abbey near Krakow, the importance of music is confirmed by a significant collection of various music books from the 16th to the 20th century preserved in the local library, and the testimony of chronicles mentioning heroic nuns who insisted on singing in the choir notwithstanding their advanced age, maladies and other afflictions. The foundation for this particular allegiance to liturgical singing had been already laid at the beginning of cloistered life The five (l) to fifteen-years—old girls, after having been received on probation, were required to learn, during a period of time not exceeding a year, to read and write in Polish and Latin, and to sing according to the rules of solmization Four 18th-century manuals provide examples of the peculiar solmization system taught by the ‘Mistress of the lay maidensl It can be inferred from the manuscripts that the first lessons included also an introduction to the tonal idiom of the eight modes for which a short tonary with psalm tones difierentiae was used Girls, as it seems, were also required to memorize the most basic repertoire including ferial antiphons for Vespers, invitatory tones and Benedicamus domino formulae The notated entries in the manuals confirm that as late as the 18th century, local, medieval melodies were preserved.

description: Hybrid propulsion generally combines a liquid oxidizer with a solid fuel. Compared to
solid or bi-liquid engines, this type of propulsion offers advantages in terms of cost
and flexibility. For several years, ONERA has been providing expertise in this area, both
in experimental and numerical simulations. Various hybrid rocket motors have been
designed and tested on ground, including under low ambient pressure conditions and
in flight. The Propulsion Laboratory unit of the DMAE uses fully instrumented engine
breadboards in order to optimize the oxidizer/fuel pair, as well as the injection system
and the combustion efficiency. In addition, 0D and 1D codes for engine design are
actively being developed. More recently, studies have been undertaken as part of the
LEOP future satellite platforms, with the development of an innovative new combustion
chamber.

description: In Argentina, a significant loss of genetic diversity, especially of traditional crops and associated knowledge, is detected which is due to the replacement of local varieties by improved ones. However, there are groups of farmers and communities that conserve local populations and are interested in recovering traditional varieties of different crops. Through the project PR-154 “Conservación y uso sostenible de los recursos fitogenéticos locales para la alimentación y la agricultura (RFAA) para contribuir a la seguridad alimentaria de los pequeños agricultores de Argentina”supported in the 4th project cycle of the Benefit-sharing Fund (BSF) of the International Treaty on Plant Genetic Resources (ITPGRFA) of the Food and Agriculture Organization (FAO); different actions related to in situ conservation and sustainable use of local PGRFA have been supported by family farmers in the Northwest, Northeast and Northern Patagonia of Argentina.

The project activities focused on the conservation and use of local varieties of potatoes, beans and maize-crops that play a central role in the world's food supply, particularly for some vulnerable communities. The germplasm conserved in INTA's banks and in the territory has also been characterized and evaluated by producers, in order to make adapted materials available to local conditions and contribute to the diversification of cropping systems.

Coordination between farmers, seed guardians and institutions succeeded in establishing networks for the conservation and circulation of native maize seeds and their value as “human food”. In this way, in situ conservation enabled both access to a strategic common good and the interaction of its associated knowledge among the producing families themselves.

This recipe booklet proposes to share a fragment of those customs rooted in the knowledge/know-how about the culinary uses of maize based on the testimonies collected in the Confluencia region. The recipes shared here therefore offer a recognition of traditional cooking habits and are also an invitation to revitalize the culinary traditions of local gastronomy.

description: Inspired on the well known dynamical dichotomy predicted in voids, where some underdense regions expand whereas others collapse due to overdense surrounding regions, we explored the interplay between the void inner dynamics and its large scale environment. The environment is classified depending on its density as in previous works. We analyse the dynamical properties of void-centered spherical shells at different void-centric distances depending on this classification. The above dynamical properties are given by the angular distribution of the radial velocity field, its smoothness, the field dependence on the tracer density and shape, and the field departures from linear theory. We found that the velocity field in expanding voids follows more closely the linear prediction, with a more smooth velocity field. However when using velocity tracers with large densities such deviations increase. Voids with sizes around $18\,h^{-1}\,Mpc$ are in a transition regime between regions with expansion overpredicted and underpredicted from linear theory. We also found that velocity smoothness increases as the void radius, indicating the laminar flow dominates the expansion of larger voids (more than $18\,h^{-1}\,Mpc$). The correlations observed suggest that nonlinear dynamics of the inner regions of voids could be dependent on the evolution of the surrounding structures. These also indicate possible scale couplings between the void inner expansion and the large scale regions where voids are embedded. These results shed some light to the origin of nonlinearities in voids, going beyond the fact that voids just quickly becomes nonlinear as they become emptier.

description: Even though the technology of cryogenic rocket engines is well mastered today,
and has been applied successfully in many launchers all over the world, research
activities on the various elementary or coupled processes involved in these complex
systems are still relevant and useful for future developments, cost reduction, and
knowledge improvement.
The Mascotte test facility was designed and built with this in mind twenty years ago.
Since then, numerous configurations have been tested, enabling almost all of the phenomena
involved in the operation of a rocket engine to be investigated, in a research
lab environment, but nevertheless under representative conditions.
Research items addressed on the Mascotte test rig include: injector concepts; liquid
oxygen jet atomization and combustion, new propellant combinations (methane instead
of hydrogen), ignition, heat transfer at the chamber walls, high frequency instabilities,
flow-separation in an over-expanded nozzle, plume and infrared signature.

description: Systems for processing big data---e.g., Hadoop, Spark, and massively parallel databases---need to run workloads on behalf of multiple tenants simultaneously. The abundant disk-based storage in these systems is usually complemented by a smaller, but much faster, {\em cache}. Cache is a precious resource: Tenants who get to use cache can see two orders of magnitude performance improvement. Cache is also a limited and hence shared resource: Unlike a resource like a CPU core which can be used by only one tenant at a time, a cached data item can be accessed by multiple tenants at the same time. Cache, therefore, has to be shared by a multi-tenancy-aware policy across tenants, each having a unique set of priorities and workload characteristics. In this paper, we develop cache allocation strategies that speed up the overall workload while being {\em fair} to each tenant. We build a novel fairness model targeted at the shared resource setting that incorporates not only the more standard concepts of Pareto-efficiency and sharing incentive, but also define envy freeness via the notion of {\em core} from cooperative game theory. Our cache management platform, ROBUS, uses randomization over small time batches, and we develop a proportionally fair allocation mechanism that satisfies the core property in expectation. We show that this algorithm and related fair algorithms can be approximated to arbitrary precision in polynomial time. We evaluate these algorithms on a ROBUS prototype implemented on Spark with RDD store used as cache. Our evaluation on a synthetically generated industry-standard workload shows that our algorithms provide a speedup close to performance optimal algorithms while guaranteeing fairness across tenants.

description: The numerical simulation of cryogenic combustion is crucial for a better understanding of the complex physics involved in reactive flows of rocket engines and to help to reduce the development cost of these engines. The focus of this study is set on the oxidizer injection and its dispersion through jet dense core destabilization and atomization or supercritical mixing. Specific models have been implemented in the CFD code CEDRE created by ONERA to address these physical phenomena

description: An arithmetic function $f$ is called a {\it sieve function of range} $Q$, if its Eratosthenes transform $g=f\astμ$ is supported in $[1,Q]\cap\N$, where $g(q)\ll_{\varepsilon} q^{\varepsilon}$ ($\forall\varepsilon>0$). Here, we study the distribution of $f$ over short {\it arithmetic bands} $\cup_{1\le a\le H}\{n\in(N,2N]: n\equiv a\, (\bmod\,q)\}$, with $H=o(N)$, and give applications to both the correlations and to the so-called weighted Selberg integrals of $f$, on which we have concentrated our recent research.

description: The valence band of a variety of few-layer, two-dimensional materials consists of a ring of states in the Brillouin zone. The energy-momentum relation has the form of a `Mexican hat' or a Rashba dispersion. The two-dimensional density of states is singular at or near the band edge, and the band-edge density of modes turns on nearly abruptly as a step function. The large band-edge density of modes enhances the Seebeck coefficient, the power factor, and the thermoelectric figure of merit ZT. Electronic and thermoelectric properties are determined from ab initio calculations for few-layer III-VI materials GaS, GaSe, InS, InSe, for Bi$_{2}$Se$_{3}$, for monolayer Bi, and for bilayer graphene as a function of vertical field. The effect of interlayer coupling on these properties in few-layer III-VI materials and Bi$_{2}$Se$_{3}$ is described. Analytical models provide insight into the layer dependent trends that are relatively consistent for all of these few-layer materials. Vertically biased bilayer graphene could serve as an experimental test-bed for measuring these effects.

description: In this paper we show how reliable measurements on porous ceramic films can be made by appropriate nanoindentation experiments and analysis. Room-temperature mechanical properties of the mixed-conducting perovskite material LSCF6428 were investigated by nanoindentation of porous bulk samples and porous films sintered at temperatures from 900-1200C. A spherical indenter was used so that the contact area was much greater than the scale of the porous microstructure. The elastic modulus of the bulk samples was found to increase from 33.8-174.3 GPa and hardness from 0.64-5.32 GPa as the porosity decreased from 45-5% after sintering at 900-1200C. Densification under the indenter was found to have little influence on the measured elastic modulus. The residual porosity in the dense sample was found to account for the discrepancy between the elastic moduli measured by indentation and by impulse excitation. Crack-free LSCF6428 films of acceptable surface roughness for indentation were also prepared by sintering at 900-1200C. Reliable measurements of the true properties of the films were obtained by data extrapolation provided that the ratio of indentation depth to film thickness was in the range 0.1 to 0.2. The elastic moduli of the films and bulk materials were approximately equal for a given porosity. The 3D microstructures of films before and after indentation were characterized using FIB-SEM tomography. Finite element modelling of the elastic deformation of the actual microstructures showed excellent agreement with the nanoindentation results.

description: Deriving minimum evolution times is of paramount importance in quantum mechanics. Bounds on the speed of evolution are given by the so called quantum speed limit (QSL). In this work we use quantum optimal control methods to study the QSL for driven many level systems which exhibit local two-level interactions in the form of avoided crossings (ACs). Remarkably, we find that optimal evolution times are proportionally smaller than those predicted by the well-known two-level case, even when the ACs are isolated. We show that the physical mechanism for such enhancement is due to non-trivial cooperative effects between the AC and other levels, which are dynamically induced by the shape of the optimized control field.
