The Acoustic Camera As A Tool To Identify Belt Conveyor Noises, Piotr Bortnowski, Anna Nowak-Szpak, Maksymilian Ozdoba, Robert Król

Journal of Sustainable Mining

This paper explores the possibilities of using an acoustic camera as a tool that allows the verification of the correct construction and operation of individual elements of a belt conveyor. Based on the simultaneously recorded components - a video camera and measuring microphones, the sound pressure level map of the belt conveyor was created. The tests were carried out in laboratory conditions and covered the location and identification of individual noise sources. The verification consists not only of searching for dominant sound sources, but above all, of searching for frequencies in the analysed spectrum that should not occur during their …

Beekeeping Practices And Challenges In The Kingdom Of Saudi Arabia: Adoption Of New Technologies And Selection Of Bee Species, Ella M. Poole

RURALS: Review of Undergraduate Research in Agricultural and Life Sciences

Apiculture (or beekeeping) is a highly profitable industry in Saudi Arabia. The Saudi national government has recognized the sector as having the potential to grow and improve the quality of life in rural areas. To expand the industry, Saudi government officials and academics are calling for beekeepers to switch from using traditional hives to moveable-frame box hives and from keeping indigenous bees to importing foreign bees. Although both changes have been shown to increase honey productivity, they are opposed by most Saudi beekeepers and increase the risk for the spread of dangerous bee diseases. This paper explores Saudi arguments for …

Teacher Immediacy Behaviors And Students’ Public Speaking Anxiety: More And Less Helpful Than Anticipated, Beau Foutz, Michelle Violanti, Stephanie Kelly, Suzanne Marie Prentiss

Basic Communication Course Annual

Public speaking anxiety inhibits students in the basic course classroom, whether face-to-face, hybrid or online, and beyond. Equipping instructors with the tools necessary to empower students to manage that anxiety and excel in their basic communication course is a goal of scholars and practitioners. In this study, the researchers examine applying and testing a math anxiety model (i.e., Kelly at al., 2015) to the challenge of public speaking anxiety. We expanded the original model by examining instructor verbal immediate behaviors alongside their nonverbal immediate behaviors. We also tested the Instructional Beliefs Model (IBM; Weber et al., 2011), which indicates that …

Studying Chinese Characters In A Web-Based Learning Environment: A Case Study Of Swedish University Students, Tao Yang, Man Gao

Chinese Language Teaching Methodology and Technology

This survey study aims to investigate the perceptions learners have of the character-learning strategies they employ when taking a web-based course in Chinese. The seven Likert-scale statements are included in the questionnaire to examine learners’ opinions on the three character-learning strategies that are widely used in traditional campus courses. A total of 65 students who completed the beginner level ‘Chinese Characters’ web-based course at a university in Sweden completed the survey. The results suggest that students in web-based courses consider these three strategies to be just as helpful and effective as campus students; moreover, the more orthodox strategy – rote …

Role Of Antizyme Inhibitor Proteins In Cancers And Beyond, Venella Tulluri, Venkatesh V. Nemmara

College of Science & Mathematics Departmental Research

Polyamines are multivalent organic cations essential for many cellular functions, including cell growth, differentiation, and proliferation. However, elevated polyamine levels are associated with a slew of pathological conditions, including multiple cancers. Intracellular polyamine levels are primarily controlled by the autoregulatory circuit comprising two different protein types, Antizymes (OAZ) and Antizyme Inhibitors (AZIN), which regulate the activity of the polyamine biosynthetic enzyme ornithine decarboxylase (ODC). While OAZ functions to decrease the intracellular polyamine levels by inhibiting ODC activity and exerting a negative control of polyamine uptake, AZIN operates to increase intracellular polyamine levels by binding and sequestering OAZ to relieve ODC …

Bhlh Iridoid Synthesis 3 Is A Member Of A Bhlh Gene Cluster Regulating Terpenoid Indole Alkaloid Biosynthesis In Catharanthus Roseus, Sanjay Kumar Singh, Barunava Patra, Priyanka Paul, Yongliang Liu, Sitakanta Pattanaik, Ling Yuan

Kentucky Tobacco Research and Development Center Faculty Publications

Basic helix‐loop‐helix (bHLH) transcription factors (TFs) are key regulators of plant specialized metabolites, including terpenoid indole alkaloids (TIAs) in Catharanthus roseus. Two previously characterized subgroup‐IVa bHLH TFs, BIS1 (bHLH Iridoid Synthesis 1) and BIS2 regulate iridoid biosynthesis in the TIA pathway. We reanalyzed the recently updated C. roseus genome sequence and discovered that BIS1 and BIS2 are clustered on the same genomic scaffold with a previously uncharacterized bHLH gene, designated as BIS3. Only a few bHLH gene clusters have been studied to date. Comparative analysis of 49 genome sequences from different plant lineages revealed the presence of analogous …

Violence And Masculinity In Small-Scale Societies, Debra L. Martin

Anthropology Faculty Research

© 2021 by The Wenner-Gren Foundation for Anthropological Research. All rights reserved. Archaeological and ethnographic accounts of violence in small-scale societies represent a baseline for thinking about the ways that violence and masculinity originated and evolved, becoming entwined social processes. Male violence (lethal and nonlethal) is expressed in diverse and complex ways because it is associated with social spheres of power and influence, and it is embedded within ideologies, histories, and collective memories. Applying anthropological research on violence as a generative and transformational social process demonstrates how violence plays a key role in creating, maintaining, and transforming social structures in …

Soil Properties Limiting Vegetation Establishment Along Roadsides, Shad D. Mills, Martha Mamo, Sabrina J. Ruis, Humberto Blanco-Canqui, Walter Schacht, Tala Awada, Xu Li, Pamela Sutton

Department of Agronomy and Horticulture: Faculty Publications

Roadside vegetation provides a multitude of ecosystem services, including pollutant remediation, runoff reduction, wildlife habitat, and aesthetic scenery. Establishment of permanent vegetation along paved roads after construction can be challenging, particularly within 1 m of the pavement. Adverse soil conditions could be one of the leading factors limiting roadside vegetation growth. In this study, we assessed soil physical and chemical properties along a transect perpendicular to the road at six microtopographic positions (road edge, shoulder, side slope, ditch, backslope, and field edge) along two highway segments near Beaver Crossing and Sargent, NE. At the Beaver Crossing site, Na concentration was …

Tomato Chlorosis Virus Infection Facilitates Bemisia Tabaci Med Reproduction By Elevating Vitellogenin Expression, Liping Huang, Xiaobin Shi, Jizhe Shi, Zhuo Zhang, Yong Fang, Zhanhong Zhang, Qiuyi Pan, Limin Zheng, Yang Gao, Deyong Zhang, Xinqiu Tan, Yong Liu, Xuguo Zhou

Entomology Faculty Publications

Transmission of plant pathogenic viruses mostly relies on insect vectors. Plant virus could enhance its transmission by modulating the vector. Previously, we showed that feeding on virus infected plants can promote the reproduction of the sweet potato whitefly, Bemisia tabaci MED (Q biotype). In this study, using a whitefly-Tomato chlorosis virus (ToCV)-tomato system, we investigated how ToCV modulates B. tabaci MED reproduction to facilitate its spread. Here, we hypothesized that ToCV-infected tomato plants would increase B. tabaci MED fecundity via elevated vitellogenin (Vg) gene expression. As a result, fecundity and the relative expression of B. tabaci MED Vg …

Manganese Exposure In Juvenile C57bl/6 Mice Increases Glial Inflammatory Responses In The Substantia Nigra Following Infection With H1n1 Influenza Virus., Collin M Bantle, C Tenley French, Jason E Cummings, Shankar Sadasivan, Kevin Tran, Richard A Slayden, Richard Jay Smeyne, Ronald B Tjalkens

Farber Institute for Neuroscience Faculty Papers

Infection with Influenza A virus can lead to the development of encephalitis and subsequent neurological deficits ranging from headaches to neurodegeneration. Post-encephalitic parkinsonism has been reported in surviving patients of H1N1 infections, but not all cases of encephalitic H1N1 infection present with these neurological symptoms, suggesting that interactions with an environmental neurotoxin could promote more severe neurological damage. The heavy metal, manganese (Mn), is a potential interacting factor with H1N1 because excessive exposure early in life can induce long-lasting effects on neurological function through inflammatory activation of glial cells. In the current study, we used a two-hit model of neurotoxin-pathogen …

Library Anxiety: An Overview Of Re-Emerging Phenomena, Nikica Gardijan

Library Philosophy and Practice (e-journal)

Since 1986, when library anxiety phenomenon was first mentioned by Mellon, numerous scientific papers have been written on this subject. The main purpose of this paper is to analyse and summarize existing scientific literature regarding library anxiety with a special emphasis on academic libraries.

By thorough review of literature authors reached two conclusions. First one being that library anxiety is a real occurrence among university library users and it impairs academic success and second that library anxiety can be prevented or alleviated by librarians.

In this paper we have listed definitions of library anxiety, scales for measuring library anxiety and …

The Use Of Insecticides To Manage The Western Corn Rootworm, Diabrotica Virgifera Virgifera, Leconte: History, Field-Evolved Resistance, And Associated Mechanisms, Lance J. Meinke, Dariane Souza, Blair D. Siegfried

Department of Entomology: Faculty Publications

The western corn rootworm, Diabrotica virgifera virgifera LeConte (Dvv) is a significant insect pest of maize in the United States (U.S.). This paper reviews the history of insecticide use in Dvv management programs, Dvv adaptation to insecticides, i.e., field-evolved resistance and associated mechanisms of resistance, plus the current role of insecticides in the transgenic era. In the western U.S. Corn Belt where continuous maize is commonly grown in large irrigated monocultures, broadcast-applied soil or foliar insecticides have been extensively used over time to manage annual densities of Dvv and other secondary insect pests. This has contributed to the sequential occurrence …

Visit-To-Visit Blood Pressure Variability And Sleep Architecture, Xiaoyue Liu, Jeongok Logan, Younghoon Kwon, Jennifer M. Lobo, Hyojung Kang, Min-Woong Sohn

Health Management and Policy Faculty Publications

Visit‐to‐visit blood pressure (BP) variability (BPV) is an independent risk factor of cardiovascular disease (CVD). Sleep architecture characterizes the distribution of different stages of sleep and may be important in CVD development. We examined the association between visit‐to‐visit BPV and sleep architecture using in‐lab polysomnographic data from 3,565 patients referred to an academic sleep center. BPV was calculated using the intra‐individual coefficient of variation of BP measures collected 12 months before the sleep study. We conducted multiple linear regression analyses to assess the association of systolic and diastolic BPV with sleep architecture—rapid eye movement (REM) and non‐rapid eye movement (NREM) …

Sustainable Bioproduction By Rhodopseudomonas Palustris Tie-1 Through Metabolic Engineering¬¬¬, Wei Bai

McKelvey School of Engineering Graduate Student Theses & Dissertations

The heavy reliance of the petroleum industry for raw material and the rising atmospheric CO2 caused by this reliance have driven the research and development of sustainable alternatives. Microbial production of chemicals, such as fuel and plastic, has been viewed as a feasible method. The wide selection of substrates by microbes enables them to produce chemicals using naturally abundant material or industrial waste, such as CO2, making the production sustainable. Compared to the model organisms such as Escherichia coli, Saccharomyces cerevisiae, many non-model organisms have a broader selection for carbon, electron, and nitrogen sources, making them great candidates for sustainable …

Malaria In Southern Venezuela: The Hottest Hotspot In Latin America, Maria Eugenia Grillet, Jorge E. Moreno, Juan V. Hernández-Villena, Maria F. Vincenti-González, Oscar Noya, Adriana Tami, Alberto Paniz-Mondolfi, Martin Llewellyn, Rachel Lowe, Ananias A. Escalante, Jan E. Conn

Harold W. Manter Laboratory of Parasitology: Library Materials

Malaria elimination in Latin America is becoming an elusive goal. Malaria cases reached a historical ~1 million in 2017 and 2018, with Venezuela contributing 53% and 51% of those cases, respectively. Historically, malaria incidence in southern Venezuela has accounted for most of the country’s total number of cases. The efficient deployment of disease prevention measures and prediction of disease spread to new regions requires an in-depth understanding of spatial heterogeneity on malaria transmission dynamics. Herein, we characterized the spatial epidemiology of malaria in southern Venezuela from 2007 through 2017 and described the extent to which malaria distribution has changed country-wide …

New Particle Formation In The Remote Marine Boundary Layer, Guangjie Zheng, Yang Wang, For Full List Of Authors, See Publisher's Website.

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Marine low clouds play an important role in the climate system, and their properties are sensitive to cloud condensation nuclei concentrations. While new particle formation represents a major source of cloud condensation nuclei globally, the prevailing view is that new particle formation rarely occurs in remote marine boundary layer over open oceans. Here we present evidence of the regular and frequent occurrence of new particle formation in the upper part of remote marine boundary layer following cold front passages. The new particle formation is facilitated by a combination of efficient removal of existing particles by precipitation, cold air temperatures, vertical …

Department of Paediatrics and Child Health

Background: The Global Enteric Multicenter Study (GEMS) determined the etiologic agents of moderate-to-severe diarrhea (MSD) in children under 5 years old in Africa and Asia. Here, we describe the prevalence and antimicrobial susceptibility of non-typhoidal Salmonella (NTS) serovars in GEMS and examine the phylogenetics of Salmonella Typhimurium ST313 isolates.
Methods: Salmonella isolated from children with MSD or diarrhea-free controls were identified by classical clinical microbiology and serotyped using antisera and/or whole genome sequence data. We evaluated antimicrobial susceptibility using the Kirby-Bauer disk diffusion method. Salmonella Typhimurium sequence types were determined using multi-locus sequence typing and whole genome sequencing was performed …
