Increasing drought is considered one of the major threats associated with climate change in central Europe. To provide an objective, quantitative tool that represents current drought conditions, the Czech Drought Monitor System (CzechDM) was established in 2012. Like other drought monitoring systems worldwide, the CzechDM uses several approaches to provide drought data. However, the CzechDM is unique internationally due to its utilization of a network of voluntary reporters (farmers) who complete a weekly online questionnaire to provide information about soil water content and the impacts of drought on crop yield. In this study, the results from the questionnaires from individual …

Omega-6 And Omega-3 Fatty Acid-Derived Oxylipins From The Lipoxygenase Pathway In Maternal And Umbilical Cord Plasma At Delivery And Their Relationship With Infant Growth, Maranda Thompson, Arzu Ulu, Ana G.

Omega-3 and omega-6 fatty acids are important for neonatal development and health. One mechanism by which omega-3 and omega-6 fatty acids exert their effects is through their metabolism into oxylipins and specialized pro-resolving mediators. However, the influence of oxylipins on fetal growth is not well understood. Therefore, the objective of this study was to identify oxylipins present in maternal and umbilical cord plasma and investigate their relationship with infant growth. Liquid chromatography–tandem mass spectrometry was used to quantify oxylipin levels in plasma collected at the time of delivery. Spearman’s correlations highlighted significant correlations between metabolite levels and infant growth. They …

Race, Public Health, And The Epidemic Of Incarceration, Thalia González, Emma Kaeser

Nebraska Law Bulletin (Selected Issues)

COVID-19 is one of the greatest health crises of our time. While increased attention on the adverse individual and population-level effects of the pandemic for incarcerated people has motivated reforms and stimulated scholarly attention on carceral policies as health policies, this is only a first step. In this moment of heightened public consciousness around racism and health across all our public systems, this essay highlights the need for broader, health-justice-centered approaches to mass incarceration along the entire continuum. As new legal reforms emerge in this moment, we challenge the public health law community to work alongside racial justice, economic justice, …

Management-Intensive Grazing Impacts On Total Escherichia Coli, E. Coli O157: H7, And Antibiotic Resistance Genes In A Riparian Stream, Laura M. Rubeck, James E. Wells, Kathy Hanford, Lisa M. Durso, Walter H. Schacht, Elaine D. Berry

Department of Agronomy and Horticulture: Faculty Publications

The impacts of management-intensive grazing (MIG) of cattle on concentrations of total Escherichia coli, total suspended solids (TSS), and nitrate-nitrite nitrogen (NO₃+NO₂-N), and occurrence of E. coli O157:H7 and selected antibiotic resistance genes (ARGs) in stream water and/or sediments were evaluated. Cattle were grazed for twoweek periods in May in each of three years. Overall, grazing increased total E. coli in downstream water by 0.89 log10 MPN/100 mL (p < 0.0001), and downstream total E. coli concentrations were higher than upstream over all sampling intervals. Downstream TSS levels also increased (p ≤ 0.0294) during grazing. In contrast, there was …

Firearms And Toolmark Error Rates, Susan Vanderplas, Kori Khan, Heike Hofmann, Alicia L. Carriquiry

Department of Statistics: Faculty Publications

We have outlined several problems with the state of error rate studies on firearm and toolmark examination. Fundamentally, we do not know what the error rate is for these types of comparisons. This is a failure of the scientific study of toolmarks, rather than the examiners themselves, but until this is corrected with multiple studies that meet the criteria described in Section 3, we cannot support the use of this evidence in criminal proceedings.

Reminiscences Of Lafcadio Hearn, Setsuko Koizumi, Paul Kiyoshi Hisada, Frederick Johnson

Zea E-Books Collection

Setsuko Koizumi (1868–1932) was the daughter of a Japanese samurai family in Matsué. In 1891 she married a foreigner — Lafcadio Hearn (1850–1904) — and their union lasted 13 years and produced three children. Hearn adopted her family name, becoming Koizumi Yakumo 小泉八雲,and spent those years in Japan writing, teaching, and achieving international recognition. Setsuko’s Reminiscences tells something of the couple’s moves and travels, but focuses mostly on the character, habits, and eccentricities of her husband. The book is a heartfelt and intimate portrait of a marriage that brought Lafcadio the home and family he had never before enjoyed. This …

Scavenger Receptors In Host Defense: From Functional Aspects To Mode Of Action, Qamar Taban, Peerzada Tajamul Mumtaz, Khalid Z. Masoodi, Ehtishamul Haq, Syed Mudasir Ahmad

Department of Nutrition and Health Sciences: Faculty Publications

Scavenger receptors belong to a superfamily of proteins that are structurally heterogeneous and encompass the miscellaneous group of transmembrane proteins and soluble secretory extracellular domain. They are functionally diverse as they are involved in various disorders and biological pathways and their major function in innate immunity and homeostasis. Numerous scavenger receptors have been discovered so far and are apportioned in various classes (A-L). Scavenger receptors are documented as pattern recognition receptors and known to act in coordination with other co-receptors such as Toll-like receptors in generating the immune responses against a repertoire of ligands such as microbial pathogens, non-self, intracellular …

Effects Of Harvest Season On Carcass Characteristics Of Lambs In The Intermountain West, J. R. Whaley, T. W. Murphy, C. L. Gifford, W. J. Means, J. P. Ritten, H. N. Mckibben, C. M. Page, W. C. Stewart

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Objective: The objectives of this study were to survey characteristics including hot carcass weight (HCW), 12th rib fat thickness (RFT), body-wall thickness (BWT), longissimus muscle area (LMA), USDA yield grade (USDA YG), percentage closely trimmed retail cuts (RC), and calculated yield grade (Calc YG) of lamb carcasses in the Intermountain West to determine the effects of season of slaughter and interrelationships among carcass characteristics.

Materials and Methods: Lamb carcass characteristics were evaluated in 2 commercial Intermountain West processing plants over one year (n = 10,027). Carcasses were evaluated by season: spring (December–April, n = 2,322) and summer (May–August, n …

Phylogenetic Tests Of Models Of Viral Transmission, Robert M. Zink, Kenedi Holck, Grant L. Morgan

School of Natural Resources: Faculty Publications

The hunt for the immediate non-human host of SARS-CoV-2 has centered on bats of the genus Rhinolophus. We explored the phylogenetic predictions of two models of viral transmission, the SpilloverModel and the CirculationModel and suggest that the Spillover Model can be eliminated. The Circulation Model suggests that viral transmission occurs among susceptible hosts irrespective of their phylogenetic relationships. Susceptibility could be mediated by the ACE2 gene (important for viral docking) and we constructed a phylogeny of this gene for 159 mammal species, finding a phylogenetic pattern consistent with established mammalian relationships. The tree indicates that viral transfer occurs over …

The ecosystem performance approach, used in a previously published case study focusing on the Nebraska Sandhills, proved to minimize impacts of non-climatic factors (e.g., overgrazing, fire, pests) on the remotely-sensed signal of seasonal vegetation greenness resulting in a better attribution of its changes to climate variability. The current study validates the applicability of this approach for assessment of seasonal and interannual climate impacts on forage production in the western United States semi-arid grasslands. Using a piecewise regression tree model, we developed the Expected Ecosystem Performance (EEP), a proxy for annual forage production that reflects climatic influences while minimizing impacts of …

Fourteen Propositions For Resilience, Fourteen Years Later, Morgan Mathisonslee, Steven J. Lade, Conor Barnes, Karina Benessaiah, Erin T.H. Crockett, Andrea S. Downing, Julie A. Fowler, Rachel Belisle-Toler, Shubhechchha Sharma, Klara J. Winkler

In 2006, Walker et al. published an article titled, “A Handful of Heuristics and Some Propositions for Understanding Resilience in Social-ecological Systems.” The article was incorporated into the Ecology and Society special feature, Exploring Resilience in Social-Ecological Systems. Walker et al. identified five heuristics and posed 14 propositions for understanding resilience in social-ecological systems. At the time, the authors hoped the paper would promote experimentation, critique, and application of these ideas in resilience and social-ecological systems research. To determine the extent to which these propositions have achieved the authors’ hopes, we reviewed the scientific literature on socialecological systems since the …

School of Natural Resources: Faculty Publications

Agricultural crop cover identification is a major issue and time-consuming effort to verify the crop type through surveys of the individual field or using prehistoric methods. To establish the scenario of crop identification, the stage of crop provides diverse spatial information about the variety of crops due to its spectral changes. The main aim of this study was to the identify the crop types and their behavior using remote sensing and geographical information system-based approach. Moreover, two main methods were applied to the Sentinel-2 satellite data in which one is random forest based supervised classification and another was Normalize Difference …
