description: The attached letter to the SHPO indicates our intent to replace all original roofing tiles on historic buildings because they are brittle and broken. In the original Section 106 letter to the SHPO in 1992 we indicated that we would use the original tiles if at all possible. In 1993, US Tile’s Bernardo Blend was selected as a replacement of the original and for future new construction roofing tiles. The sentence in the first Section 106 letter to the SHPO we sent to your office and was changed so as not to give the erroneous indication that we selected Bernardo Blend now - May 97. See paragraph 4 of the attached letter. The determination was No Adverse Effect rather than No Effect; therefore, additional coordination with the Advisory Council on Historic Preservation (ACHP) is required.
Stellar intensity interferometry over kilometer baselines: Laboratory simulation of observations with the Cherenkov Telescope Array

description: A long-held astronomical vision is to realize diffraction-limited optical aperture synthesis over kilometer baselines. This will enable imaging of stellar surfaces and their environments, show their evolution over time, and reveal interactions of stellar winds and gas flows in binary star systems. An opportunity is now opening up with the large telescope arrays primarily erected for measuring Cherenkov light in air induced by gamma rays. With suitable software, such telescopes could be electronically connected and used also for intensity interferometry. With no optical connection between the telescopes, the error budget is set by the electronic time resolution of a few nanoseconds. Corresponding light-travel distances are on the order of one meter, making the method practically insensitive to atmospheric turbulence or optical imperfections, permitting both very long baselines and observing at short optical wavelengths. Theoretical modeling has shown how stellar surface images can be retrieved from such observations and here we report on experimental simulations. In an optical laboratory, artificial stars (single and double, round and elliptic) are observed by an array of telescopes. Using high-speed photon-counting solid-state detectors and real-time electronics, intensity fluctuations are cross correlated between up to a hundred baselines between pairs of telescopes, producing maps of the second-order spatial coherence across the interferometric Fourier-transform plane. These experiments serve to verify the concepts and to optimize the instrumentation and observing procedures for future observations with (in particular) CTA, the Cherenkov Telescope Array, aiming at order-of-magnitude improvements of the angular resolution in optical astronomy.

description: Many predictions of Doppler cooling theory of two-level atoms have never been verified in a three-dimensional geometry, including the celebrated minimum achievable temperature $\hbar Γ/2 k_B$, where $Γ$ is the transition linewidth. Here, we show that, despite their degenerate level structure, we can use Helium-4 atoms to achieve a situation in which these predictions can be verified. We make measurements of atomic temperatures, magneto-optical trap sizes, and the sensitivity of optical molasses to a power imbalance in the laser beams, finding excellent agreement with the Doppler theory. We show that the special properties of Helium, particularly its small mass and narrow transition linewidth, prevent effective sub-Doppler cooling with red-detuned optical molasses.

description: Внутригодовая геохимическая изменчивость атмосферных осадков была прослежена на модельной территории Курской биосферной станции Института географии РАН (КБС). Основными объектами опробования были снежный покров в конце снегонакопления и дождевые осадки за теплый период года 2017 г. Установлено, что зимние атмосферные осадки отличаются очень малой минерализацией, слабокислой реакцией, минимальными концентрациями химических элементов. Подщелачивание дождевой влаги происходит в весенне-летний период во время распашки агроландшафтов. Для дней с дождями были рассчитаны обратные траектории движения воздушных масс (NOAA HYSPLIT MODEL). Выявлено, что основной вклад в геохимию атмосферных осадков вносят воздушные массы западного сектора. Преобладающий западный перенос воздушных масс привносит в ландшафты тяжелые металлы: никель, железо, кобальт, медь, цинк. Атмосферные осадки являются значимым источником поступления в лесостепные ландшафты селена и бериллия. Внутригодовая изменчивость химического состава атмосферных осадков может являться индикатором атмосферного загрязнения и оказывать заметное антропогенное влияние на фоновые лесостепные ландшафты модельной территории Курской биосферной станции ИГ РАН.
description: Geochemical variability of precipitation during the year was observed on the model territory of the Kursk Biosphere station of the Institute of Geography of RAS (KBS). The snow at the end of accumulation and rainfall during the warm period of 2017 were sampled. The results showed that winter precipitation has very low mineralization, slightly acidic pH, and minimal concentrations of chemical elements. Alkalization of rainwater occurs in the spring-summer period during the plowing of agricultural landscapes. Backward trajectories of air masses (NOAA HYSPLIT MODEL) for days with rain showed potential pollution sources. Air masses of the western sector make the main contribution to the geochemistry of atmospheric precipitation. The predominant western transfer of air mass carries heavy metals in the landscapes: nickel, iron, cobalt, copper, zinc. The precipitation is an important income source of selenium and beryllium in forest-steppe landscapes. The variability of the chemical content of precipitation during the year can be an indicator of the air pollution and provide significant anthropogenic influence on natural forest-steppe landscapes of the Kursk Biosphere Station.

description: The nature of the magnetic field fluctuations in the solar wind between the ion and electron scales is still under debate. Using the Cluster/STAFF instrument, we make a survey of the power spectral density and of the polarization of these fluctuations at frequencies $f\in[1,400]$ Hz, during five years (2001-2005), when Cluster was in the free solar wind. In $\sim 10\%$ of the selected data, we observe narrow-band, right-handed, circularly polarized fluctuations, with wave vectors quasi-parallel to the mean magnetic field, superimposed on the spectrum of the permanent background turbulence. We interpret these coherent fluctuations as whistler mode waves. The life time of these waves varies between a few seconds and several hours. Here we present, for the first time, an analysis of long-lived whistler waves, i.e. lasting more than five minutes. We find several necessary (but not sufficient) conditions for the observation of whistler waves, mainly a low level of the background turbulence, a slow wind, a relatively large electron heat flux and a low electron collision frequency. When the electron parallel beta factor $β_{e\parallel}$ is larger than 3, the whistler waves are seen along the heat flux threshold of the whistler heat flux instability. The presence of such whistler waves confirms that the whistler heat flux instability contributes to the regulation of the solar wind heat flux, at least for $β_{e\parallel} \ge$ 3, in the slow wind, at 1 AU.

description: We describe a statistical technique, which we call Moment Component Analysis (MCA), that extends Principal Component Analysis (PCA) to higher co-moments such as co-skewness and co-kurtosis. This method allows us to identify the factors that drive co-skewness and co-kurtosis structures across a large set of series. We illustrate MCA using 44 international stock markets sampled at weekly frequency from 1994 to 2014. We find that both the co-skewness and the co-kurtosis structures can be summarized with a small number of factors. Using a rolling window approach, we show that these co-moments convey useful information about market returns, for systemic risk measurement and portfolio allocation, complementary to the information extracted from a standard PCA or from an Independent Component Analysis.

On the Feeding Zone of Planetesimal Formation by the Streaming Instability
Creators: name: Yang, Chao-Chin
name: Johansen, Anders
Publisher: name: arXiv
Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The streaming instability is a promising mechanism to overcome the barriers in direct dust growth and lead to the formation of planetesimals. Most previous studies of the streaming instability, however, were focused on a local region of a protoplanetary disk with a limited simulation domain such that only one filamentary concentration of solids has been observed. The characteristic separation between filaments is therefore not known. To address this, we conduct the largest-scale simulations of the streaming instability to date, with computational domains up to 1.6 gas scale heights both horizontally and vertically. The large dynamical range allows the effect of vertical gas stratification to become prominent. We observe more frequent merging and splitting of filaments in simulation boxes of high vertical extent. We find multiple filamentary concentrations of solids with an average separation of about 0.2 local gas scale heights, much higher than the most unstable wavelength from linear stability analysis. This measures the characteristic separation of planetesimal forming events driven by the streaming instability and thus the initial feeding zone of planetesimals.

description: Airborne wind energy systems aim to harvest the power of winds blowing at altitudes higher than what conventional wind turbines reach. They employ a tethered flying structure, usually a wing, and exploit the aerodynamic lift to produce electrical power. In the case of ground-based systems, where the traction force on the tether is used to drive a generator on the ground, a two phase power cycle is carried out: one phase to produce power, where the tether is reeled out under high traction force, and a second phase where the tether is recoiled under minimal load. The problem of controlling a tethered wing in this second phase, the retraction phase, is addressed here, by proposing two possible control strategies. Theoretical analyses, numerical simulations, and experimental results are presented to show the performance of the two approaches. Finally, the experimental results of complete autonomous power generation cycles are reported and compared with first-principle models.

description: The distribution of magnetic flux across the solar photosphere results in a complex web of coronal magnetic field structures. To understand this complexity, the magnetic skeleton of the coronal field can be calculated. The skeleton highlights the separatrix surfaces that divide the field into topologically distinct regions, allowing open-field regions on the solar surface to be located. Furthermore, separatrix surfaces and their intersections (separators) are important likely energy release sites. This paper investigates, throughout the solar cycle, the nature of coronal magnetic-field topologies that arise under the potential-field source-surface approximation. In particular, we characterise the typical global fields at solar maximum and minimum. Global magnetic fields are extrapolated from observed Kitt Peak and SOLIS synoptic magnetograms, from Carrington rotations 1645 to 2144, using the potential-field source-surface model. Hence, variations in the coronal skeleton are studied over three solar cycles. Key building blocks which make up magnetic fields are identified and classified according to the nature of their separatrix surfaces. The magnetic skeleton reveals that, at solar maximum, the global coronal field involves a multitude of topological structures at all latitudes. Many open-field regions exist originating anywhere on the photosphere. At solar minimum, the coronal topology is heavily influenced by the solar dipole. A strong dipole results in a simple large-scale structure involving just two large polar open-field regions, but, at short radial distances between plus or minus 60 deg latitude, the small-scale topology is complex. If the solar dipole if weak, as in the recent minimum, then the low-latitude quiet-sun magnetic fields may be globally significant enough to create many disconnected open-field regions at low latitudes, in addition to the two polar open-field regions.
Anaerobic Benzene Degradation in Albertan Sediments
Creators: Lee, Korris
Publisher: name: University of Alberta Library
Year: 2022

ABSTRACT

Benzene is a priority contaminant that is commonly coincident with fossil fuel entities, whether

natural or anthropogenic, and is characterized by high mobility and toxicity. In Alberta, Canada,

where oil and gas production comprises much of the provincial industrial output, benzene

contamination presents an omnipresent environmental risk to health and safety, necessitating

economical methods that can minimize such threats. In this study, bioremediation is

investigated as a benzene removal option for contaminated sites. Bioremediation can involve

the use of microorganisms to metabolize benzene, and typically requires either the potentiation

of available microbes (i.e. biostimulation) or the introduction of external microbes (i.e.

bioaugmentation) in situ. Remediators can benefit greatly in using indigenous cultures that have

been developed to maximize degradative capabilities and minimize time burden. This project,

therefore, is focused on the generation of anaerobic benzene degrading cultures (under

methanogenic, sulfate-reducing, iron-reducing, and nitrate-reducing conditions) derived from

indigenous Albertan sediments and analysis of their community properties and primary degrader

populations, while investigating different strategies to enhance their metabolic performance.

These include the implementation of iron-dissolution protocols with external chelators such as

acetohydroxamic acid and oxalic acid to expand ferric iron pools, and the addition of conductive

magnetite at nano and micrometer scales to enhance the conductivity of microbial morphologies

that can ease the transfer of electrons for metabolism. Lastly, an attempt was made to produce

the putative benzene carboxylase AbcDA in vitro and subvert the difficulties of culture creation

and maintenance entirely.

The research in this thesis demonstrated robust degradation of benzene in cultures sourced

from Albertan sediments in a multitude of redox conditions, including nitrate-reducing, ironreducing,

sulfate-reducing, and methanogenic contexts, with iron and nitrate-reducers exhibiting

the highest levels of benzene degradation (11-12 uM/d). Primary benzene degraders were

iii

identified in nitrate-reducing and iron-reducing cultures, namely Peptococcaceae and

Geobacter, respectively. Geobacter metallireducens was also identified at a species taxonomic

level in iron-reducing cultures. While the isolation of Geobacter from iron-reducing cultures was

unsuccessful, and putative benzene hydroxylases gmet 0231-0232 were not found within these

consortia, the potential of certain chelator combinations such as acetohydroxamic acid (aHA)

and oxalic acid in enhancing the benzene degrading performance of iron-reducing cultures was

demonstrated, although their specific functions within these cultures could not be elucidated.

Protecting Agricultural Land: How Informal Institutions and Historical Perspectives Affect Land-Use Policy
Creators: Epperson,Darren,M
Publisher: name: University of Alberta Library
Year: 2022

Land-use pressures in Alberta's agricultural landscapes have intensified in recent years. With the province's broad historical agricultural base and ongoing urban expansion, there have been growing concerns about the loss of prime agricultural land. These concerns and conflicts have been reflected in recent provincial policies that attempt to balance competing land-use pressures. These policies include the 2008 Land-Use Framework (LUF) and the 2009 Alberta Land Stewardship Act (ALSA), which authorizes the creation of policies and management strategies to protect, conserve and enhance agricultural land (ALSA: Government of Alberta, 2009). However, local interpretations concerning province-wide land-use policies and perceived restrictions on private land use have hindered the desired outcomes (Lavelle, 2012).

Since the creation of Alberta’s most recent land use policies, various studies have reported a persistent pattern of fragmentation and conversion of prime agricultural lands. While several research projects have measured the spatial context and implications of converting agricultural lands, few have attempted to assess the non-spatial causes of continuing conversion and fragmentation of agricultural land. Following a qualitative case study approach, this research aims to understand better how factors such as social norms and informal institutions influence land-use decisions at the municipal level, focusing on decisions affecting the fragmentation and conversion of agricultural land. This study also considers how these informal factors affect the application of Alberta's land-use policies and formal mandates.

description: We use the tomographic density of states (TDoS), which is a measure of the density of states for a single slice through the band structure of a solid, to study the temperature evolution of the superconducting gap in the cuprates. The TDoS provides unprecedented accuracy in determining both the superconducting pair-forming strength, $Δ$, and the pair-breaking rate, $Γ$. In both optimally- and under-doped Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$, we find the near-nodal $Δ$ smoothly evolves through the superconducting transition temperature - clear evidence for the existence of pre-formed pairs. Additionally, we find the long observed `filling' of the superconducting gap in the cuprates is due to the strongly temperature dependent $Γ$.
SoDa-TAP: A Data Platform for Social Media Analysis
Creators: Gutierrez Gutierrez, Candelario A.
Publisher: name: University of Alberta Library
Year: 2022

Social media platforms are online public venues where conversations about a wide range of public interests take place. Users can interact within a social platform in two ways: (i) they can post an opinion, talk about an event, or share a personal status, optionally accompanied with a video, an image, url(s), and/or hashtag(s); or (ii) they can like, share, reply and/or quote another user's post. Social platforms are known to generate high volume of interactions: a large number of users are frequently participating in online conversations, and share their ideas or thoughts on issues. Private and public organizations have shown interest in the data that is generated from these interactions with the purpose of monitoring topics, events, brands, and/or persons of interest. This data then allows them to make informed, event-driven decisions. In order to achieve this, there is a necessity for Social Media Analytics systems that facilitate the collection, processing, storage and extraction of insights from social media data.

In this thesis, we present SoDa-TAP (Social Data - Toolkit Analysis Platform), an automated, scalable, and extensible data platform that offers three key functionalities: (a) Data Workflow: data extraction of posts' elements and metadata, calculation of secondary metrics, and multiple visualizations for data exploration; (b) Engagement Calculation: analysis and calculation of multiple indicators of influence from the posts' data; and (c) Statistics Toolkit: a toolkit for descriptive statistical analysis and information visualization. We demonstrate the platform's potential in two ways. First we describe the software architecture and how the interconnectivity of each component supports fast and scalable deployment. The second is the presentation of two case studies that we performed, to show the ability to measure influence using official Twitter accounts from the University of Alberta, and its adaptability to provide insights about conversations and content engagement around energy, during the "Energy East Pipeline" timeline.
