Adoption of Exhaust Air Dust Testing in SPF Rodent Facilities
Authors: Pettan-Brewer Christina , Trost Riley J , Maggio-Price Lillian , Seamons Audrey , Dowling Susan C
Published: February 2020

Reliable detection of unwanted microbial agents is essential for meaningful health monitoring in laboratory animal facilities. Most rodents at our institution are housed in IVC rack systems to minimize aerogenic transmission of infectious agents between cages. The most commonly used
rodent health monitoring systems expose live sentinel rodents to soiled bedding collected from other rodent cages on IVC racks and subsequently test these soiled-bedding sentinels for evidence of infection with excluded agents. However, infectious agents might go undetected when using this
health surveillance method, due to inefficient organism shedding or transmission failure. In 2016, our institution switched the health monitoring methodology for the majority of our SPF rodent colonies to real-time PCR testing of environmental samples collected from the exhaust plenums of
IVC racks. Here we describe our rationale for this conversion, describe some interesting health monitoring cases that arose soon after the conversion, and discuss a potential problem with the conversion—residual nucleic acids. We compared cost and implementation effort associated with
2 sampling methods, sticky swabs and in-line collection media. We also compared the ability of these 2 sampling methods to detect 2 prevalent microbes in our facilities, Helicobacter and murine norovirus. Our institution-wide switch to health monitoring by real-time PCR assay of exhaust
air dust samples thus far has provided a sensitive, simple, and reliable approach for maintenance of SPF conditions in laboratory rodents and has dramatically reduced the use of live sentinel animals.
Teaching on Religion and Violence
Authors: Bellinger Charles
Published: February 2020

I have many times now taught a course entitled “Religion and Violence” at Brite Divinity School and Texas Christian University. The Brite course is in-class; the TCU course is online with Master of Liberal Arts students. I will describe the difference between the two formats and also provide sample syllabi. The course has traditionally focused on the “why” question--“Why are human beings violent?”--rather than on ethical debates about pacifism vs. just war. Feedback from the online students often asked for another course focusing on peacemaking, now that the psychology of violence has become better understood. I therefore developed a new course called “Peacemaking in a Violent World,” which will also be described. I will make the argument that our culture as a whole would benefit from greater curricular attention to the psychology of violence, at all levels of education. I will also provide attendees with a bibliography for collection development in this area.
Building Collaboration with Faculty and Instructional Designers
Authors: Kumar Beth , Schiefelbein-Guerrero Kyle
Published: February 2020

Librarians are often working together within the library, but collaborating with faculty and instructional designers can benefit your students, faculty, and staff. Many large libraries have whole teams working collaboratively, but in a theological library you might be working at a much smaller scale, with a limited budget. This pre-conference focused on approaches that a small team (one librarian and one instructional designer/faculty member) has developed to collaborate across their departments to build a suite of services and collections to serve their patrons. The workshop allowed time to develop a plan of action to bring away three concrete items on which to collaborate with the faculty or instructional designers at your school.
Defining Digital Theology: Barthian Reflections on the Role of Open Access and Electronic Publishing in the Theological Toolkit
Authors: MoChridhe Race
Published: February 2020

As a student member of the Atla Press Coordinating Committee, the presenter has spent the past eight months evaluating, developing, and implementing digital tools to support the Press' initiatives in open access scholarship. This session frames those efforts in the context of theology's status as a "minor participant" (Hutchings 2015) in the digital humanities as well as the emergence of a trans-disciplinary domain increasingly identified as “digital theology” (Phillips 2014). Drawing on Anderson’s (2018) analysis of theology’s disciplinary distance from the main body of digital humanities work, the presenter outlines a case for the distinctive primacy of digital publishing tools and open access commitments in digital theology, as compared with the broader suite of research tools and methods that constitute the “cultural capital” (Schroeder 2016) of digital humanities as generally understood. Particular attention is paid in this regard to Karl Barth’s vision of a “proclamation-centered” (Hector, 2015) theological method as the basis for an ecclesiological critique of closed access publication models.

Explorations in Bibliography: Zotero Goes Public
Authors: Morrison Greg
Published: February 2020

The publishing of scholarly bibliographies has diminished significantly over the past two decades for an obvious reason: access to bibliographic tools via the Internet. But this has not marked the end altogether of research-level bibliographies, which are still vital to the preservation and advancement of knowledge. Research bibliographies are finding a new home online, and open source tools are now available to help scholars and librarians reestablish this genre in dynamic fashion.  This listen and learn session discussed one such project that deploys Zotero, Tablesorter, and Libguides to serve a targeted group of users.
First Nations/Native Americans and Religion: Bibliographic Conversation and Recommendations
Authors: Schmersal David Edward , Elder Jane
Published: February 2020

A quick search using the subject “Indians of North America – Religion” in Bridwell Library’s catalog retrieved 130 results out of a collection of about 490,000 volumes. This suggests (a) The Library of Congress may want to consider revising some of its subject headings (but that is a topic for another time), (b) religious and spiritual practices among native North Americans/First Nations are not widely studied by our students. While there are certainly exceptions, likely this situation is not unique among theological libraries. This session represents an effort to rectify this by sharing and inviting colleagues to share recommendations of resources on spirituality and religious beliefs and practices of various native North American/First Nations groups and their relation to the faith traditions that are more broadly represented in our collections.

Three Credits' Worth of Research: The Librarian as Research Advisor for MA Candidates
Authors: Humble James
Published: February 2020

In addition to the MDiv degree, granted after three years of graduate study, students at St. Charles Borromeo Seminary in Wynnewood, Pennsylvania, can complete their requirements for the MA degree in Theology in their fourth and final year by writing a thesis paper. Several years ago, in an effort to ensure that the candidates were performing an acceptable level of research before beginning writing, academic administrators enjoined the librarian to supervise them during the fall semester of that fourth year, when their courseload is lighter. The students now earn three credits for the research they do. Thus, without the framework of regular class meetings, the librarian had not only to advise each student individually on the best sources and research techniques suited to his subject, but to encourage the students to work consistently, without the structural benefits that traditional courses provide, in the hope that the students will produce academically satisfactory work. The author will relate the trial-and-error course he took to bring this enterprise to its current form, and share some of the methods that he uses to keep on top of all the students throughout their research journey.

Catalogers and Directors: At Loggerheads or Mutually Advancing the Profession?
Authors: Lammert Richard Allen , Hicks Heather , Vianney Stephen , Phillips Thomas
Published: February 2020

Especially in recent years, the future of cataloging as a part of the library profession has become a point of discussion. It seems at times that catalogers and directors are at opposite parts of the spectrum: catalogers holding on to cataloging because “that’s the way it’s always been done”; directors trying to make use of dwindling funds, and deciding that cataloging as we know it is not a major part of the future. So it seems—but is the appearance accurate? Are catalogers and directors simply saying the same thing in different ways and with different focuses, or is there a fundamental disconnect between the two viewpoints? The purpose of this panel was to bring together one cataloger and two directors to discuss precisely that topic.

ALTERNATIVE ENERGY SOURCES FOR INCREASING ENERGY EFFICIENCY OF IRRIGATION SYSTEMS
Authors: Dekhtiar O. O.
Published: February 2020

Actuality of the problem. The article discusses the current level of use of alternative sources of electrical power in the world. The main areas of the global power development were determined, the statistical data of leading energy companies, analytical international organizations and financial institutions were analysed. For today, all civilized countries successfully switch to alternative energy sources: wind, solar energy, biofuels, etc. In addition, the use of solar energy is one of the most promising inexhaustible, renewable energy sources. The use of renewable energy sources replaces the traditional one, based on extractive technologies polluting the atmosphere with harmful emissions, and enhances the greenhouse effect, reduces the burden on the resource base and energy systems of countries and improves the environment. Sustainable development of the agricultural sector of the economy of Ukraine and, in particular, irrigated agriculture requires a reduction in energy dependence. In the structure of the cost of irrigation water, a significant share accounts for electrical power. That is why to increase the efficiency of irrigated agriculture, to ensure high and sustainable yields in the context of climate change, it is extremely important to reduce the cost of power consumption. The need to use alternative energy sources in the drainage complex of Ukraine as part of the implementation of the energy strategy of Ukraine, aimed at the transition to fficient use and consumption of energy resources is highlighted. The Institute of Water Problems and Land Reclamation deals with the investigations of measures and technologies to improve power efficiency to reduce the specific energy consumption for pumping water by pumping stations and to reduce the rate of power losses for water intake and water transportation by water supply paths. One of the effective measures to reduce power cost is the use of alternative energy sources, in particular solar energy. The economic potential of the measures for improving energy efficiency in irrigation systems wass estimated. Conclusions. The estimation showed that the use of modules of solar power plants installed above the surface of open irrigation canals will lead to lower energy costs in the face of a constant increase in tariffs, that is, it will help to increase the economic efficiency of irrigation, reduce the share of water resources in national energy consumption and have a positive environmental effect. The sale of surplus power to the energy system at “green” tariffs can significantly reduce the payback period for the modernization of the engineering infrastructure of irrigation systems.

The research method used is literacy (literature study). In addition, the Prediction, Observation, Explanation, Elaboration, Write and Evaluation (POE2WE) learning model was developed from the POEW learning model and the Physics learning model with a Constructiveivistic Approach. Therefore, information has an important and real role, in the era of the information society or the information society. POE2WE learning model can make students as subjects in learning. students actively find a concept through direct observation or experimentation, not from memorizing material books or explanations from the teacher. This model allows active students in the learning process, gives students the opportunity to construct their knowledge, communicate their thoughts and write down the results of the discussion so that students are more mastered and understand the concepts that will have an impact on increasing student learning achievement. The application of learning innovation through Digital Technology in Physics learning with the POE2WE model is categorized as a new thing. The development of this model touches the realm of e-learning in response to the demands of the industrial revolution 4.0.
Comparison of Markov versus quantum dynamical models of human decision making
Authors: Busemeyer Jerome R , Kvam Peter D. , Pleskac Timothy Joseph
Published: February 2020

What kind of dynamic decision process do humans use to make decisions? In this article, two different types of processes are reviewed and compared: Markov and quantum. Markov processes are based on the idea that at any given point in time a decision maker has a definite and specific level of support for available choice alternatives, and the dynamic decision process is represented by a single trajectory that traces out a path across time. When a response is requested, a person's decision or judgment is generated from the current location along the trajectory. By contrast, quantum processes are founded on the idea that a person's state can be represented by a superposition over different degrees of support for available choice options, and that the dynamics of this state form a wave moving across levels of support over time. When a response is requested, a decision or judgment is constructed out of the superposition by 'actualizing' a specific degree or range of degrees of support to create a definite state. The purpose of this article is to introduce these two contrasting theories, review empirical studies comparing the two theories, and identify conditions that determine when each theory is more accurate and useful than the other.

Conflicts Between Work and Family and Displaced Aggression with Working Parents in South Korea: An Exploratory Study
Authors: Kim Eunha , Shin Yun-Jeong , Kim Jisu
Published: February 2020

Because the related domains of work-family conflict and family-work conflict have become significant issues for Korean dual-career couples, we examined whether the satisfaction of autonomy needs (feelings of agency, volition, and initiating one’s own actions) in a marriage would moderate the relationship between work-family conflicts and displaced aggression toward family. In addition, we investigated whether such moderating effects would be different for men and women. The results revealed that the satisfaction of autonomy needs in marital relationships buffered the negative effects of work-family conflicts on displaced aggression toward family, although this effect was significant only for men. In contrast, the satisfaction of autonomy needs had a moderating effect on the association between family-work conflicts and displaced aggression toward family for women, but not for men.

13th-century fortifications of Kraków
Authors: Niemiec Dariusz
Published: February 2020

The paper recapitulates the current state of knowledge about the fortifications of the three basic settlement units of 13th-century Kraków, namely Wawel, Okół, and the city established under Magdeburg Law. With respect to Wawel, written accounts have survived that clearly point to large-scale construction works on timber-and-earth defences of the stronghold undertaken in 1258 and 1265; these fortifications have partly been uncovered by archaeological research close to the southern edge of the hill. The northern section of the moat protecting the Kraków suburbium known as Okół (by the southern border of Wszystkich Świętych Square and Dominikańska Street) probably ceased to function in 1191 due to its destruction during the struggles among provincial dukes vying for control over Kraków. New archaeological investigations of the moat in the area between Poselska and Senacka Streets suggest that in the second half of the 13th century the area of Okół was constricted, with its northern boundary moved back to the line running between these two streets. The earliest planned attempt at fortifying the city of Kraków did not take place before 1285–1287, and it was undertaken on the initiative of Duke Leszek Czarny. It is worth emphasising that at the initial stage it was connected with incorporation of an older Dominican mill-race (mentioned before 1284) into the new system of defences. The construction of the full defensive perimeter in the form of timber-and-earth ramparts and moats must have been completed before the third Mongol invasion, which reached Kraków in the winter of 1287. The remains of a moat connected with the oldest fortifications of the city of Kraków, presumably created during the reign of Leszek Czarny on the northern side of the Church of St. Mark, were archaeologically identified on a parcel at 26 Sławkowska Street. The western line of a moat of the same age was confirmed in several places in the westernmost part of the University Quarter. The construction of Kraków city walls after 1298, during the reign of Wacław II and Władysław Łokietek, was connected with expanding the area of the city in virtually all directions beyond the line marked by older fortifications from the times of Leszek Czarny.

Published: February 2020

Albino tea mutants with specific shoot colors (white or yellow) have received increasing attention from researchers due to their unique phenotypes, beneficial metabolites, and special flavor. In this study, novel natural yellow leaf mutants of the same genetic background of “Rougui” were obtained, and the transcriptome and metabolite profiles of the yellow leaf mutant (YR) and original green cultivar (GR) were investigated. A total of 130 significantly changed metabolites (SCMs) and 55 differentially expressed genes (DEGs) were identified in YR compared to GR. The leaf coloration of YR was primarily affected by pigment metabolism including of chlorophyll, carotenoids, and flavonoids, and the co-expression of three heat shock proteins (HSPs) and four heat shock transcription factors (HSFs) may also regulate leaf coloration by affecting chloroplast biogenesis. Of the 130 SCMs, 103 showed clearly increased abundance in YR, especially nucleotides and amino acids and their derivatives and flavonoids, suggesting that YR may be an ideal albino tea germplasm for planting and breeding. Our results may help to characterize the leaf coloration and metabolic mechanism of albino tea germplasm.

In the present study, Ni50Ti50 (NiTi) particle reinforced aluminum nanocomposites were fabricated using microwave sintering and subsequently hot extrusion. The effect of NiTi (0, 0.5, 1.0, and 1.5 vol %) content on the microstructural, mechanical, thermal, and damping properties of the extruded Al-NiTi nanocomposites was studied. Compared to the unreinforced aluminum, hardness, ultimate compression/tensile strength and yield strength increased by 105%, 46%, 45%, and 41% while elongation and coefficient of thermal expansion (CTE) decreased by 49% and 22%, respectively. The fabricated Al-1.5 NiTi nanocomposite exhibited significantly higher damping capacity (3.23 × 10−4) and elastic modulus (78.48 ± 0.008 GPa) when compared to pure Al.

With the increase of water depth, the design and use of the top-tensioned risers (TTR) are facing more and more challenges. This research presents the effect of top tension on dynamic behavior of deep-sea risers by means of numerical simulations and experiments. First, the governing equation of vortex-induced vibration (VIV) of TTR based on Euler-Bernoulli theory and Van der Pol wake-oscillator model was established, and the effect of top tension on natural vibration of TTR was discussed. Then, the dynamic response of TTR in shear current was calculated numerically by finite difference method. The displacement, bending stress and vibration frequency of TTR with the variation of top tension were investigated. Finally, a VIV experiment of a 5 m long flexible top-tensioned model was carried out at the towing tank of Tianjin University. The results show that the vibration displacement of TTR increases and the bending stress decreases as the top tension increases. The dominant frequency of VIV of TTR is controlled by the current velocity and is barely influenced by the top tension. With the increase of top tension, the natural frequency of TTR increases, the lower order modes are excited in the same current.

Published: February 2020

A three degrees-of-freedom model based on the potential flow theory was implemented to represent the motion of a slender cylindrical buoy under waves. The model calibration was performed by means of the comparison between the model results and the experiments performed at the Laboratory of Hydraulic Engineering of the University of Bologna (Italy). The dynamics of the floating cylinder, placed at the mid-section of the wave flume and anchored at the bottom through a mooring system of four catenaries, were obtained through videography analysis, providing surge, heave and pitch motions. The implementation of the mathematical model consisted of two main parts: The first has been developed in the frequency domain by applying NEMOH to assess the hydrodynamic coefficients of the object, i.e., the excitation, radiation and added mass coefficients; then, the used mooring system was included in the time-domain model, solving the motion of the floating cylinder, by calibrating the mooring coefficients by comparing the results with the data. The simplicity of the implemented model is a very important feature, and it should be used as a preliminary study to understand the response of moored floating cylinders and others floating bodies under waves.

The recycling of millions of tons of glass bottle waste produced each year is far from optimal. In the present work, ground blast furnace slag (GBFS) was substituted in fly ash-based alkali-activated mortars (AAMs) for the purpose of preparing glass bottle waste nano-powder (BGWNP). The AAMs mixed with BGWNP were subsequently subjected to assessment in terms of their energy consumption, economic viability, and mechanical and chemical qualities. Besides affording AAMs better mechanical qualities and making them more durable, waste recycling was also observed to diminish the emissions of carbon dioxide. A more than 6% decrease in carbon dioxide emissions, an over 16% increase in compressive strength, better durability and lower water absorption were demonstrated by AAM consisting of 5% BGWNP as a GBFS substitute. By contrast, lower strength was exhibited by AAM comprising 10% BGWNP. The conclusion reached was that the AAMs produced with BGWNP attenuated the effects of global warming and thus were environmentally advantageous. This could mean that glass waste, inadequate for reuse in glass manufacturing, could be given a second life rather than being disposed of in landfills, which is significant as concrete remains the most commonplace synthetic material throughout the world.

Published: February 2020

The surface of SnO2 nanowires was functionalized by chitosan for the development of room-temperature conductometric humidity sensors. SnO2 nanowires were synthesized by the seed-mediated physical-vapor-deposition (PVD) method. Chitosan layers were deposited on top of the SnO2 nanowires by spin coating. Surface morphology, crystal structure, and optical properties of the synthesized hybrid nanostructure were investigated by scanning electron microscope, grazing incidence X-ray diffraction, and UV–Vis absorption measurements. During electrical conductivity measurements, the hybrid nanostructure showed unusual behavior towards various relative humidity (RH) concentrations (25%, 50%, 75%), under UV-light irradiation, and in dark conditions. The highest sensor responses were recorded towards an RH level of 75%, resulting in 1.1 in the dark and 2.5 in a UV-irradiated chamber. A novel conduction mechanism of hybrid nanowires is discussed in detail by comparing the sensing performances of chitosan film, SnO2 nanowires, and chitosan@SnO2 hybrid nanostructures.

This work was aimed to obtain and characterize the well-defined biocomposites based on β-tricalcium diphosphate(V) (β-TCP) co-doped with Ce3+ and Pr3+ ions modified by poly(l-lactide) (PLLA) with precise tailored chain length and different phosphate to polymer ratio. The composites as well as β-tricalcium diphosphate(V) were spectroscopically characterized using emission spectroscopy and luminescence kinetics. Morphological and structural properties were studied using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The self-assembled poly(l-lactide) in a shape of rose flower has been successfully polymerized on the surface of the β-tricalcium diphosphate(V) nanocrystals. The studied materials were evaluated in vitro including cytotoxicity (MTT assay) and hemolysis tests. The obtained results suggested that the studied materials may find potential application in tissue engineering.

GaAs has been demonstrated to be a promising material for manufacturing semiconductor light-emitting devices and integrated circuits. It has been widely used in the field of aerospace, due to its high electron mobility and wide band gap. In this study, the structural and photoelectric characteristics of Si-doped GaAs under different gamma irradiation doses (0, 0.1, 1 and 10 KGy) are investigated. Surface morphology studies show roughen of the surface with irradiation. Appearance of transverse-optical (TO) phonon mode and blueshift of TO peak reflect the presence of internal strain with irradiation. The average strain has been measured to be 0.009 by Raman spectroscopy, indicating that the irradiated zone still has a good crystallinity even at a dose of 10 KGy. Photoluminescence intensity is increased by about 60% under 10 KGy gamma irradiation due to the strain suppression of nonradiative recombination centers. Furthermore, the current of Si-doped GaAs is reduced at 3V bias with the increasing gamma dose. This study demonstrates that the Si-doped GaAs has good radiation resistance under gamma irradiation, and appropriate level of gamma irradiation can be used to enhance the luminescence property of Si-doped GaAs.
