Synthesis and characterizations of antimicrobial coating by atomic layer deposition technique for personal protective equipment applications
Creators: name: Tao, Li
Publisher: name: University of British Columbia
Year: 2023

description: The outbreak of COVID-19 has led to significant demand for Personal Protective Equipment (PPE), such as masks and face shields. While these PPEs can protect people from many infectious agents, they usually are one-time use and non-degradable after disposal, causing a shortage of supply and environmental issues. While many reusable substitutes, such as reusable cloth masks, were developed, their prevention capability might be compromised after prolonged usage. As such, self-disinfecting coatings have been applied to PPEs to improve antibacterial and antiviral properties. However, commercial coating methods, such as spraying and physical vapor deposition, have several limitations for PPE applications, including poor coverage, loose adhesion, and high coating temperature. This thesis work adopted an advanced atomic layer deposition (ALD) technique to fabricate nanoscale self-disinfecting coatings that overcome the above mentioned coating approaches limitations. This work investigated the ALD fabrication, material characterizations, and antimicrobial performance of titanium oxide (TiO₂) and zinc oxide (ZnO), two typical UV-activated self-disinfecting materials. The ALD-deposited TiO₂ and ZnO thin films on the glass substrate had thickness of 81.6 ± 6.6 nm and 312.8 ± 41.3 nm, respectively. Structural analysis by X-ray diffraction, Raman spectroscopy, and X-ray photoelectron microscopy confirmed the successful deposition of TiO₂ and ZnO, most of which were amorphous. The antimicrobial properties of the ALD-TiO₂ and ZnO were evaluated against E. coli, under modified AATCC-100 standard, with commercial TiO₂ and ZnO powders as references. Data indicated that ALD-ZnO could eliminate E. coli during a 12-hour test. All the data were verified through P value test with alpha set to 0.05, and statistically proved the antimicrobial performance of the ALD-ZnO. Moreover, the nanoscale ALD-ZnO exhibited antimicrobial properties similar to commercial ZnO. On the other hand, P-value tests indicated ALD-TiO₂ coating and commercial TiO₂ powders did not generate statistically significant data that suggests antimicrobial activity toward E. coli. The different antimicrobial properties of ALD-ZnO and TiO₂ could be caused by more substantial UV absorption capability of the former than the latter, as revealed by the UV absorption test. It is expected that this work could stimulate the application of the ALD technique for applying self-disinfecting ZnO coatings for PPE.

description:
The reliable estimation of the dynamic storage capacity for CO2 storage is a significant challenge due to the uncertainty of process parameters. In our study, we consider storage in the Triassic Bunter sandstone underneath the German sector of the North Sea.

We investigate CO2 injection into a saline aquifer, such as the Volpriehausen Sandstone by means of numerical simulations, to analyze the impact of parameter uncertainty on storage efficiency.

One of the main challenges for capacity estimations is the paucity of measurements regarding storage rock units like the Volpriehausen Sandstone for important process parameters such as relative permeabilities obtained from wells in the German North Sea. This requires the supplementation of measured parameters from the same storage rock units for instance from neighboring countries such as the Netherlands or Denmark.

We conduct flow simulations using TOUGH3 ECO2N and a self-developed framework for sensitivity analysis to investigate the parameter uncertainty of process parameters on storage efficiency.

Our results indicate that the level of uncertainty can significantly affect the estimation of storage capacity, and the accuracy of simulation results is highly dependent on certain input parameters.

This study provides insights into the impact of parameter uncertainty on the efficiency of CO2 storage. These findings are useful for future exploration, characterization, and operation of CO2 storage sites.

description: The K-shell emission line of neutral irons from the Galactic center (GC) region is one of the key for the structure and activity of the GC. The origin is still open question, but possibly due either to X-ray radiation or to electron bombarding to neutral atoms. To address this issue, we analyzed the Suzaku X-ray spectrum from the GC region of intense neutral iron line emission, and report on the discovery of Kalpha lines of neutral argon, calcium, chrome, and manganese atoms. The equivalent widths of these Kalpha lines indicate that the metal abundances in the GC region should be ~1.6 and ~4 of solar value, depending on the X-ray and the electron origins, respectively. On the other hand, the metal abundances in the hot plasma in the GC region are found to be ~1-2 solar. These results favor that the origin of the neutral Kalpha lines are due to X-ray irradiation.

description: This document describes the relationship of EOSC-Pillar with the EOSC governance and the EOSC related initiatives (EOSC-Rel). We briefly describe how the EOSC was structured before the creation of the EOSC-Association and the main results achieved by the WG’s that were established by the Executive Board of EOSC, which was a body of representatives from the research and e-infrastructures communities, appointed by the European Commission, with a mandate ending in December 2020. Then we describe the transition phase that has led to the present situation with the new EOSC-Association with its board of Directors, partner of the EC in the EU Partnership that is being established, together with the new Steering Board representing the Member States and Associated Countries. The setting up of the new Advisory Groups intended to complete and further develop the work of the previous WG’s toward a fully valid EOSC is sketched and the role of EOSC-Pillar in the new structure of EOSC is shown. The main aspects of the collaboration of EOSC-Pillar with the other projects, starting with the regional ones, are then described. The status of the National Initiatives supported by EOSC-Pillar in the countries where it is established is then briefly addressed. Finally, we give an outlook of the EOSC-Rel activities in the near future and with the new incoming projects and conclude on the positive role played till now by EOSC-Pillar and the positive role expected for the EOSC future.

description: (abridged) We found in previous studies that standard Simple Stellar Population (SSP) models are unable to describe or explain the colours of Galactic open clusters both in the visible and in the NIR spectral range. (...) We construct a numerical SSP-model, with an underlying Salpeter IMF, valid within an upper $m_u$ and lower $m_l$ stellar mass range, and with total masses $M_c=10^2...10^4\,m_\odot$ typical of open clusters. We assume that the mass loss from a cluster is provided by mass loss from evolved stars and by the dynamical evaporation of low-mass members due to two-body relaxation. The data for the latter process were scaled to the models from high-resolution N-body calculations. We also investigate how a change of the $m_l$-limit influences magnitudes and colours of clusters of a given mass and derive a necessary condition for a luminosity and colour flash. The discreteness of the IMF leads to bursts in magnitude and colour of model clusters at moments when red supergiants or giants appear and then die. The amplitude of the burst depends on the cluster mass and on the spectral range; it is strongly increased in the NIR compared to optical passbands. In the discrete case, variations of the parameter $m_l$ are able to substantially change the magnitude-age and $M/L$-age relations. For the colours, the lowering of $m_l$ considerably amplifies the discreteness effect. The influence of dynamical mass loss on colour and magnitude is weak, although it provides a change of the slopes of the considered relations, improving their agreement with observations. For the Galactic open clusters we determined luminosity and tidal mass independent of each other. The derived mass-to-luminosity ratio shows, on average, an increase with cluster age in the optical, but gradually declines with age in the NIR. The observed flash statistics can be used to constrain $m_l$ in open clusters.

description: In self-tuning brane-world models with extra dimensions, large contributions to the cosmological constant are absorbed into the curvature of extra dimensions and consistent with flat 4d geometry. In models with conventional Lagrangians fine-tuning is needed nevertheless to ensure a finite effective Planck mass. Here, we consider a class of models with non conventional Lagrangian in which known problems can be avoided. Unfortunately these models are found to suffer from tachyonic instabilities. An attempt to cure these instabilities leads to the prediction of a positive cosmological constant, which in turn needs a fine-tuning to be consistent with observations.

The electron-hole spin interactions and s,p-d interactions between the electron, the hole and the magnetic impurity are also included. The exciton energy levels and optical transitions are evaluated using the exact diagonalization scheme. A novel mechanism is proposed here to manipulate impurity-spin in the quantum dot which allows us to drive selectively the spin of the magnetic atom into each of its six possible orientations.

Marrying Anthropocentrism to Ecocentrism: The Rising Voices of Dissent in American Environmentalism
Creators: name: Bakari, Mohamed E.
Publisher: name: ASJ
Year: 2019

description: In light of multiple significant incidents in its contemporary history, the American environmental movement (EM) seems to be at a crossroads as the national consensus on this movement—forged during the 1970s—starts to crack under the strain of rising challenges. Communities most adversely affected by environmental hazards—usually referred to as communities of color and labor—now seem to be estranged from and ignored by a mostly ecocentric movement they can hardly identify with. Against such a backdrop,I examine the emergence of new dissenting ‘anthropocentric’ voices within the American EM—most notably the Environmental Justice Movement (EJM)—and discuss the multiple facets of the anthropocentric-ecocentric divide and its bearing on the evolution of the movement. I will further analyze whether the emerging sustainability discourse will be able to contain this ideological divide and offer a reconciliation framework for a harmonization of these movements’ objectives, policies, and modes of activism.

Nurse Angélique : revisioning French Catholic nursing history as an ethical intervention in contemporary Canadian nursing practice
Creators: name: Philbert, J. Kyra
Publisher: name: University of British Columbia
Year: 2023

description: The social justice mandate of Canadian nursing ethics drives the profession to intervene on systems of inequity, like racism. Canadian nurses from the Black diaspora repeatedly report experiencing racial discrimination in their everyday practice. This occupational violence is sustained by Canadian nursing’s reliance and perpetual reproduction of the ideologies of whiteness and femininity. The ethics of Canadian nursing is demonstrated to be contrary to its actions as evidenced by the experiences of Black nurses. Those concerns are not new, just like Black folks in Canada are not new. In 1734, a Black woman known as Angélique was convicted of arson by the government of New France. For her crime, she was publicly executed in the town centre of Montréal. Present-day scholars recognize the significance of the court record of Angélique’s trial: those documents are primary historical evidence that slavery was practiced in Canada. In this a/r/tographic exploration, openings are formed. Openings are emotional, uncomfortable, messy, and relational. The connections between Angélique, as a history of resistance, and contemporary Canadian nursing practice are reconnoitred through the living-inquiry of a/r/tography. The artistic component reimagined Angélique as a modern Covid-19 nurse while asking what makes Blackness so surprising in Canadian nursing? The inquiry generated from the artmaking involved reinterpreting Angélique’s story vis-à-vis early French Catholic nursing history and analysing how the current scholarship about the celebrated genesis of Canadian nursing naturalizes ideologies of whiteness and femininity. The revisioning of our shared nursing history through a Black feminist intersectional lens, with sexuality a key vector of analysis, produced a sweaty concept of “the Canadian nurse”. The reader is invited to negotiate their own meaning about these openings with no solutions, recommendations, or strategies are provided. The future of nursing needs to be anti-racist [+ anti-colonial] if it wants to realign itself with disciplinary obligations towards social justice. The future of nursing must be accountable to its past. Embracing our reinterpreted history despite its shattering of the benevolence of the Canadian nurse. Finally, the future of nursing benefits from being imagined beyond the current limits of what is considered “good” and “moral” nursing.
Leveraging the Hero: Witnesses and Personal Stories as Persuasive Devices in Trump’s 2018 State of the Union Address

Publisher: name: ASJ
Year: 2019

description: Acknowledging guests during the State of the Union address is not a new practice; however, it has had a peripheral role in the overall architecture of the speech, with presidents typically acknowledging up to seven guests. In his 2018 State of the Union address, president Trump acknowledges no less than eighteen guests, transforming this otherwise marginal practice into an essential part of his discourse. This article analyzes, from a socio-rhetorical perspective, President Trump’s unprecedented use of real-life individuals for image-building purposes during the 2018 State of the Union Address. I use sociological, rhetorical and linguistic concepts such as framing, narrative persuasion and demeanor indexicals to analyze the way Trump portrays the guests as heroes, integrates each into a brief narrative, and finally positions himself as hierarchically superior to them. Finally, I suggest potential directions for further research into the sociological, philosophical, political and cultural implications of this uncommon persuasive strategy.

description: A molecular dynamics study of a two dimensional system of particles interacting through a Lennard-Jones pairwise potential is performed at fixed temperature and vanishing external pressure. As the temperature is increased, a solid-to-liquid transition occurs. When the melting temperature $T_c$ is approached from below, there is a proliferation of dislocation pairs and the elastic constant approaches the value predicted by the KTHNY theory. In addition, as $T_c$ is approached from above, the relaxation time increases, consistent with an approach to criticality. However, simulations fail to produce a stable hexatic phase using systems with up to 90,000 particles. A significant jump in enthalpy at $T_c$ is observed, consistent with either a first order or a continuous transition. The role of external pressure is discussed.

description: In this article we provide numerical and analytical evidence that some degenerate dispersive partial differential equations are ill-posed. Specifically we study the K(2,2) equation $u_t = (u^2)_{xxx} + (u^2)_{x}$ and the "degenerate Airy" equation $u_t = 2 u u_{xxx}$. For K(2,2) our results are computational in nature: we conduct a series of numerical simulations which demonstrate that data which is very small in $H^2$ can be of unit size at a fixed time which is independent of the data's size. For the degenerate Airy equation, our results are fully rigorous: we prove the existence of a compactly supported self-similar solution which, when combined with certain scaling invariances, implies ill-posedness (also in $H^2$).

The potential floor between the two barriers is higher than 2mc^2 whereas the top of the barriers is at least 2mc^2 above the floor. The relativistic version of the conventional double barrier transmission resonance is obtained for energies within + or - mc^2 from the height of the barriers. However, we also find two more (sub-barrier) transmission resonance regions below the conventional one. Both are located within the two Klein energy zones and characterized by resonances that are broader than the conventional ones.

The morphology of the NT's has been characterized by Transmission Electron Microscopy (TEM) while the metallic elements have been quantified by Instrumental Neutron Activation Analysis (INAA) technique. The static and dynamic magnetic properties were studied collecting data of magnetization as a function of magnetic field and temperature and by Electron Paramagnetic Resonance (EPR). We observed that the incorporation of metallic ions (Co2+, S=3/2 and Ni2+, S=1) decrease notably the amount of V4+ ions in the system, from 14-16% (non-doped case) to 2-4%, with respect to the total vanadium atoms into the tubular nanostructure, improving considerably their potential technological applications as Li-ion batteries cathodes.

description: We describe a method to measure and subtract the incoherent component of energy flow arising from multiple interactions from jet shape/substructure observables of ultra-massive jets. The amount subtracted is a function of the jet shape variable of interest and not a universal property. Such a correction is expected to significantly reduce any bias in the corresponding distributions generated by the presence of multiple interactions, and to improve measurement resolution. Since in our method the correction is obtained from the data, it is not subject to uncertainties coming from the use of theoretical calculations and/or Monte Carlo event generators. We derive our correction method for the jet mass, angularity and planar flow. We find these corrections to be in good agreement with data on massive jets observed by the CDF collaboration. Finally, we comment on the linkage with the concept of jet area and jet mass area.

description: We investigate the ground state of the two-dimensional Heisenberg antiferromagnet on two Archimedean lattices, namely, the maple-leaf and bounce lattices as well as a generalized $J$-$J'$ model interpolating between both systems by varying $J'/J$ from $J'/J=0$ (bounce limit) to $J'/J=1$ (maple-leaf limit) and beyond. We use the coupled cluster method to high orders of approximation and also exact diagonalization of finite-sized lattices to discuss the ground-state magnetic long-range order based on data for the ground-state energy, the magnetic order parameter, the spin-spin correlation functions as well as the pitch angle between neighboring spins. Our results indicate that the "pure" bounce ($J'/J=0$) and maple-leaf ($J'/J=1$) Heisenberg antiferromagnets are magnetically ordered, however, with a sublattice magnetization drastically reduced by frustration and quantum fluctuations. We found that magnetic long-range order is present in a wide parameter range $0 \le J'/J \lesssim J'_c/J $ and that the magnetic order parameter varies only weakly with $J'/J$. At $J'_c \approx 1.45 J$ a direct first-order transition to a quantum orthogonal-dimer singlet ground state without magnetic long-range order takes place. The orthogonal-dimer state is the exact ground state in this large-$J'$ regime, and so our model has similarities to the Shastry-Sutherland model. Finally, we use the exact diagonalization to investigate the magnetization curve. We a find a 1/3 magnetization plateau for $J'/J \gtrsim 1.07$ and another one at 2/3 of saturation emerging only at large $J'/J \gtrsim 3$.

description: We study a magnetic field effect on the Non-Fermi Liquid (NFL) which arises around the quantum critical point (QCP) due to the competition between the f^2-crystalline-electric-field singlet and the Kondo-Yosida singlet states by using the numerical renormalization ground method. We show the characteristic temperature T_F^*, corresponding to a peak of a specific heat, is not affected by the magnetic field up to H_z^* which is determined by the distance from the QCP or characteristic energy scales of each singlet states. As a result, in the vicinity of QCP, there are parameter regions where the NFL is robust against the magnetic field, at an observable temperature range T > T_F^*, up to H_z^* which is far larger than T_F^* and less than min(T_{K2}, $Delta).

title: Myths of the Western Front
Creators: name: Galer, Graham Stanley
Publisher: name: University of Kent
Year: 2023

description: This thesis is an exploratory essay into ways in which a number of myths have emerged from the experience of those who fought on the Western Front in 1914-1918. The approach adopted comprises a presentation of some of the myths, and an analysis of the ways in which they have been represented in literature. Three principal myths are identified, and are termed “Loss, Anger and Futility” (LAF), “Renewal through Sacrifice” (RTS) and “Reconciliation and Regeneration” (RR). The first two myths are particular examples of general myths of war, which gave rise to ‘liberal’ and ‘conservative’ experiences of WW1. RR is a myth of reconciliation which evolved from LAF and RTS, and which, it is suggested, underpins the movement for European unity which gained strength in the post-WW2 years. The tools used to analyse the expression of the myths through literature are ‘mythic consciousness’, and myth as derived from ‘remembered communitas\ or from the ‘retrospective transfiguration of a sacrificial crisis’. The theoretical work from which these concepts arise is due respectively to Ernst Cassirer, Victor Turner and René Girard. These tools are employed to analyse three groups of writings inspired by the experience of the Western Front. These groups are referred to in the thesis as the ‘First Wave’ (during and soon after the war), the ‘Second Wave’ (around 1930) and the ‘Third Wave’ (post-1990). Within the First and Second Waves, particular attention is given to the writings of Siegfried Sassoon and Ernst Jünger. The perspective adopted in this thesis suggests that, from a mythological point of view, the Western Front may be seen as the ‘founding murder’ of the present-day European Union.
How Property Shapes Distributional Preferences

description: We study how distributional preferences are affected by a major property rights reform that transformed informal use-rights over land traditionally characterizing rural Beninese villages in a system akin to private ownership. The design combines the randomized control-trial implementation of the reform across villages with lab-in-the-field experiments eliciting villagers’ distributional choices – both when luck is the source of situational inequality and when an unequal distribution is originated by merit considerations. Results show that reforming allocation rules in the direction of impersonal market-alike institutions increases participants’ acceptance of inequality determined by luck, while leaving participants’ tolerance for inequality generated by merit unaffected.
From "a doubtful privilege" to "the solo in every concert" : the oboist's tuning-A in John Corigliano's "Tuning Game"

description: In the modern symphony orchestra, it is common practice for the musicians to tune to the principal oboist’s note A– known as the “tuning-A”– at the beginning of a concert. Although tuning the orchestra is widely accepted by orchestral musicians and audiences as an important part of the oboist’s job, there is a lack of academic research on the practice. We do not yet have a clear understanding of why the oboist gives the tuning-A– a practice whose origins Geoffrey Burgess and Bruce Haynes call a “mystery” in their well-researched history of the instrument, The Oboe (2004). Further, because the practical knowledge required to successfully play the A has mainly been passed aurally from oboist to oboist, there is little written documentation of the practice. In this dissertation, I begin to document the oboist’s relationship to the orchestral tuning-A from three different perspectives. In Chapter One, using primary historical sources from the seventeenth to the twentieth centuries, I trace the emergence of the oboist as the orchestral tuner around 1800 in Paris and the continued debates surrounding the oboe’s suitability for tuning into the nineteenth and twentieth centuries. In Chapter Two, I discuss the findings of my original online survey of practicing principal oboists in Canadian professional orchestras, including evidence that oboists see the tuning-A not only as a practical tool, but as an expressive solo. I also address possible reasons for the oboe’s continued role in modern orchestral tuning, including the instrument’s unique timbre and oboists’ ability to adjust pitch. In Chapter Three, I present my analysis of the first movement of acclaimed American composer John Corigliano’s (1938- ) Oboe Concerto (1975), called “Tuning Game,” which the composer describes as “an extension of the preperformance tuning rite into a virtuosic game.” Using Hepokoski and Darcy’s Sonata Theory (2006) as a starting point, my original analysis shows the ingenuity of Corigliano’s use of the tuning-A as a defining compositional feature of “Tuning Game”—a perspective that no scholar has contributed before. Ultimately, I argue that the oboist’s tuning-A is a musical object with rich aesthetic value.

description:
Crocodylomorpha, the crocodylian stem-lineage, is the only pseudosuchian clade that survived into the Jurassic. Its earliest members, the non-crocodyliform crocodylomorphs or ‘sphenosuchians’, were terrestrial and mostly small-bodied (<2 m long). A redescription of both known European ‘sphenosuchian’ taxa is provided, Terrestrisuchus gracilis from the Late Triassic (Norian-Rhaetian?) of southern Wales, and Saltoposuchus connectens from the Norian of southwestern Germany. Terrestrisuchus and Saltoposuchus can clearly be distinguished based on many character states, contrary to some previous hypotheses. A new phylogenetic analysis finds that both taxa form a clade of gracile, long-legged crocodylomorphs, identified as Saltoposuchidae, together with Litargosuchus leptorhynchus. Analysis of a µCT-scan provides a virtually complete threedimensional reconstruction of the Terrestrisuchus braincase. The quadrate only forms a small, unfused contact with the prootic, contrary to later crocodylomorphs in which the braincase is heavily fused to surrounding cranial elements. The posterior skull region is extensively pneumatised by, among others, large pre- and postcarotid recesses on the parabasisphenoid and a large pneumatic cavity within the articular of the mandible, revealing extensive braincase pneumatisation occurred early within Crocodylomorpha. Terrestrisuchus preserves an ossified basihyal and scleral ring, the latter representing the first occurrence among non-bird-line archosaurs. Based on phylogenetic flexible discriminant analysis (pFDA) of the relative dimensions of the sclerotic ring and orbit, Terrestrisuchus was likely active in a range of light levels. Histological long bone sections of both Terrestrisuchus and Saltoposuchus reveal highly vascularized fibrolamellar tissue, indicating sustained high growth rates and thus high resting metabolic rates and active lifestyles for saltoposuchids.

description: We explore the dynamics of non-interacting particles loaded into a phase-modulated one-dimensional lattice formed by laterally oscillating square barriers. Tuning the parameters of the driven unit cell of the lattice selected parts of the classical phase space can be manipulated in a controllable manner. We find superdiffusion in position space for all parameters regimes. A directed current of an ensemble of particles can be created through locally breaking the spatiotemporal symmetries of the time-driven potential. Magnitude and direction of the current are tunable. Several mechanisms for transient localization and trapping of particles in different wells of the driven unit cell are presented and analyzed.

description: It has been conjectured that a complete set of mutually unbiased bases in a space of dimension d exists if and only if there is an affine plane of order d. We introduce affine constellations and compare their existence properties with those of mutually unbiased constellations, mostly in dimension six. The observed discrepancies make a deeper relation between the two existence problems unlikely.

description: Understanding the behavior of hydrogen in hexagonal tungsten carbide (WC) is of particular interest for fusion reactor design due to the presence of WC in the divertor of fusion reactors. Therefore, we use first-principles calculations to study the hydrogen behavior in WC. The most stable interstitial site for the hydrogen atom is the projection of the octahedral interstitial site on tungsten basal plane, followed by the site near the projection of the octahedral interstitial site on carbon basal plane. The binding energy between two interstitial hydrogen atoms is negative, suggesting that hydrogen itself is not capable of trapping other hydrogen atoms to form a hydrogen molecule. The calculated results on the interaction between hydrogen and vacancy indicate that the hydrogen atom is energetically trapped by vacancy and the hydrogen molecule can not be formed in mono-vacancy. In addition, the hydrogen atom bound to carbon is only found in tungsten vacancy. We also study the migrations of hydrogen in WC and find that the interstitial hydrogen atom prefers to diffusion along the c axis. Our studies on the hydrogen behavior in WC provide some explanations for the experimental results of the thermal desorption process of energetic hydrogen ion implanted into WC.

description:
Both the sustainable use of our resources and the prevention of geohazards requires reliable information about the spatial distribution of soil and geological properties. Since direct measurements are costly, artificial intelligence (AI) methods are used to estimate these attributes, leveraging a machine learning algorithm which relates laboratory measurements or expert class information to environmental covariates derived, e.g. from relief, geology and climate data. This study evaluates random forest (RF) as an AI technique to predict the occurrence of debris on slopes of the entire Black Forest in 10 m resolution. It also examines whether RF models can be applied to measured geogenic radon potential (GRP) for assessing the risk of possibly harmful radon concentrations inside buildings in Baden-Wuerttemberg.

A suite of 6770 expert class labels indicating whether hillside debris of at least 1 m thickness occurs or not, were associated with main geological classes and various terrain attributes obtained from a LiDAR-based digital elevation model. RF classification showed very good results with an accuracy rate of 86 %. GRP mapping is currently based on 580 radon measurements in soil gas at 1 m depth and a set of covariates comprising soil attributes, climate variables and geological data such as uranium concentrations. Preliminary results indicate that the GRP map generated by using a state-specific RF model is highly useful in identifying municipalities as vulnerable areas for which action is needed to mitigate this particular threat to human health.
