description: This report develops the 1971-72 handling and storage costs associated with operating 175 commercial grain elevators in the United States. Standardized book costs for grain storage were 8.3 cents per bushel. Based on 1971-72 replacement value of the elevator's physical plant, the average yearly storage cost per bushel was 14.9 cents. Projecting storage costs to 1973-74 price levels and volumes shows an estimated 15 percent increase to 17.2 cents per bushel. A special study of 37 inland and port terminals shows capital and operating costs for dust control systems averaged 6.58 cents and 1.54 cents per bushel of storage capacity, respectively, and 1.16 and 0.27 cents per bushel of grain handled.

description: We show that introducing long-range Coulomb interactions immediately lifts the massive ground state degeneracy induced by geometric frustration for electrons on quarter-filled triangular lattices in the classical limit. Important consequences include the stabilization of a stripe-ordered crystalline (global) ground state, but also the emergence of very many low-lying metastable states with amorphous "stripe-glass" spatial structures. Melting of the stripe order thus leads to a frustrated Coulomb liquid at intermediate temperatures, showing remarkably slow (viscous) dynamics, with very long relaxation times growing in Arrhenius fashion upon cooling, as typical of strong glass formers. On shorter time scales, the system falls out of equilibrium and displays the aging phenomena characteristic of supercooled liquids above the glass transition. Our results show remarkable similarity with the recent observations of charge-glass behavior in ultra-clean triangular organic materials of the $θ$-(BEDT-TTF)$_2$ family.

description: In this work we deal with the presence of braneworld solutions in a five-dimensional space-time with a single extra spatial dimension of infinite extent. The braneworld scenario is built under the presence of a single real scalar field, and we modify the gravity sector to include generic function of the Gauss-Bonnet term. We study several specific models, and we construct exact braneworld solutions, in particular for including the Gauss-Bonnet term at first and second order power. As an interesting result, we show that the brane tends to split for a specific modification in the gravity sector, in the presence of non constant Gauss-Bonnet term.

description: This review article explores the possibility of developing an integrated approach to the management of the different needs of endometrial cancer (EC) patients seeking to become pregnant. Life preservation of the woman, health preservation of the baby, a precocious and—as much as possible—minimally invasive characterization of the health and fertility parameters of the patient, together with the concerns regarding the obstetric, neonatal, and adult health risks of the children conceived via assisted reproductive techniques (ART) are all essential aspects of the problem to be taken into consideration, yet the possibility to harmonize such needs through a concerted and integrated approach is still very challenging. This review aims to illustrate the main features of EC and how it affects the normal physiology of pre-menopausal women. We also focus on the prospect of a miR-based, molecular evaluation of patient health status, including both EC early diagnosis and staging and, similarly, the receptivity of the woman, discussing the possible evaluation of both aspects using a single specific panel of circulating miRs in the patient, thus allowing a relatively fast, non-invasive testing with a significantly reduced margin of error. Finally, the ethical and legal/regulatory aspects of such innovative techniques require not only a risk-benefit analysis; respect for patient autonomy and equitable health care access allocation are fundamental issues as well.

description: We show that the transition origins of electronic excitations identified by quantified natural transition orbital (QNTO) analysis can be employed to connect potential energy surfaces (PESs) according to their character across a widerange of molecular geometries. This is achieved by locating the switching of transition origins of adiabatic potential surfaces as the geometry changes. The transition vectors for analysing transition origins are provided by linear response time-dependent density functional theory (TDDFT) calculations under the Tamm-Dancoff approximation. We study the photochemical CO ring opening of oxirane as an example and show that the results corroborate the traditional Gomer-Noyes mechanism derived experimentally. The knowledge of specific states for the reaction also agrees well with that given by previous theoretical work using TDDFT surface-hopping dynamics that was validated by high-quality quantum Monte Carlo calculations. We also show that QNTO can be useful for considerably larger and more complex systems: by projecting the excitations to those of a reference oxirane molecule, the approach is able to identify and analyse specific excitations of a trans-2,3-diphenyloxirane molecule.

Improving medication education at discharge: a quality improvement project
Creators: name: Villada, Maria Alejandra
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of the Project: Patients are at risk of adverse effects due to poor understanding of their medications. A key element affecting patient understanding is ineffective communication between nurses and patients. The purpose of this quality improvement project was to improve medication education using evidence-based tools such as the teach-back method to increase nurses’ adherence to the teach-back and to routinely provide written medication education.Methodology: A pre/post-education study design was used to evaluate nurses’ knowledge of the teach-back method and how to provide written medication education to patients at discharge and to encourage compliance. A total of 30 nurses were included in this project. A post-implementation interview of 30 nurses’ attitudes and changes in practice was conducted after the intervention period. A retrospective chart review of 120 records (60 pre and 60 post-implementation) was completed to evaluate adherence to using teach-back and providing written medication information in the after-visit summary and documentation of teach-back techniques.Results: The results of this project demonstrated that implementing an educational workshop significantly improved post-test scores (p =.003) and increased documentation of patient-specific written medication education at discharge X2 (1, N = 120) = 14.13, p =.002. No significant difference was found between pre-and post-intervention of documentation of teach-teach back (1, N = 120) = 24, p > .05. The interviews provided insight into the language barriers nurses encounter during discharge education.Implications for Practice: The results of this QI project demonstrate that knowledge and adherence can be changed by implementing simple educational interventions to reinforce the use of the teach-back method and written medication education.

description: В летний период дневные температуры в г. Апатиты практически не отличаются от температуры воздуха в его пригородах. Значительные положительные аномалии температуры воздуха в городе (до 6–8°С) могут возникать ночью в тихую и ясную погоду. Аккумуляция солнечной радиации городскими конструкциями и последующая его отдача воздуху является главным механизмом формирования ночного острова тепла летом. Однако разность температуры на городском и фоновом холмах не усиливается с увеличением суммы накопленной городом в предшествующие сутки солнечной радиации. Накопленная днем в городе солнечная радиация быстро выносится за пределы приземного слоя и практически не оказывает никакого влияния на тепловой режим приземного слоя воздуха в городе. Это указывает на слабую интенсивность городского острова тепла.

The galaxy - dark matter halo connection: which galaxy properties are correlated with the host halo mass?

description: We demonstrate how the properties of a galaxy depend on the mass of its host dark matter subhalo, using two independent models of galaxy formation. For the cases of stellar mass and black hole mass, the median property value displays a monotonic dependence on subhalo mass. The slope of the relation changes for subhalo masses for which heating by active galactic nuclei becomes important. The median property values are predicted to be remarkably similar for central and satellite galaxies. The two models predict considerable scatter around the median property value, though the size of the scatter is model dependent. There is only modest evolution with redshift in the median galaxy property at a fixed subhalo mass. Properties such as cold gas mass and star formation rate, however, are predicted to have a complex dependence on subhalo mass. In these cases subhalo mass is not a good indicator of the value of the galaxy property. We illustrate how the predictions in the galaxy property - subhalo mass plane differ from the assumptions made in empirical models of galaxy clustering by reconstructing the model output using a subhalo abundance matching scheme. In its simplest form, abundance matching generally does not reproduce the clustering predicted by the models, typically resulting in an overprediction of the clustering signal. We show how the basic abundance matching scheme can be extended to reproduce the model predictions more faithfully, which has implications for the analysis of galaxy clustering, particularly for low abundance samples.

description: To support the successful integration of community pharmacies into value-based care models, research on the feasibility and effectiveness of novel pharmacist-provided patient care services is needed. The UNC Eshelman School of Pharmacy, supported by the National Association of Chain Drug Stores (NACDS) Foundation, designed the Community-based Valued-driven Care Initiative (CVCI) to (1) identify effective value-based patient care interventions that could be provided by community pharmacists, (2) implement and evaluate the feasibility of the selected patient care interventions, and (3) develop resources and create collaborative sustainability opportunities. The purpose of this manuscript is to describe recruitment strategies for CVCI and share lessons learned. The project team identified pharmacies for recruitment through a mixed data analysis followed by a “fit” evaluation. A total of 42 pharmacy organizations were identified for recruitment, 24 were successfully contacted, and 9 signed on to the project. During recruitment, pharmacies cited concerns regarding the financial sustainability of implementing and delivering the patient care services, challenges with staffing and infrastructure, and pharmacists’ comfort level. To foster participation, it was vital to have leadership buy-in, clear benefits from implementation, and assured sustainability beyond the research period.

description: Background: Inequities in COVID-19 vaccine accessibility and reliable COVID-related information disproportionately affected marginalized racial and ethnic communities in the U.S. The Get Out the Vaccine (GOTVax) program, an innovative statewide government-funded COVID-19 vaccine canvassing program in California, aimed to reduce structural barriers to COVID-19 vaccination in high-risk communities with low vaccination rates. GOTVax consisted of a community-academic-government partnership with 34 local trusted community-based organizations’ (CBOs) to conduct COVID-19 vaccine outreach, education, and vaccine registration. The purpose of this qualitative evaluation study was to explore the barriers and facilitators of using local CBOs to deploy a geographically, racially, and ethnically diverse state-wide COVID-19 vaccine outreach program. Methods: Semi-structured online interviews were conducted with participating GOTVax CBO leaders from November 2021 to January 2022. Transcripts were analyzed using reflexive thematic analysis. Results: Thirty-one of 34 CBOs participated (91% response rate). Identified themes encompassed both facilitators and barriers to program participation. Key facilitators included leveraging trust through recognized entities; promoting empathetic, tailored outreach; and flexibility of milestone-based CBO funding contracts for rapid program implementation. Barriers included navigating community sociopolitical, geographic, and cultural factors; managing canvassers’ safety; desiring metrics for self-evaluation of outreach success; mitigating canvassing technology challenges; and concerns of program infrastructure initially limiting outreach. CBOs problem-solved barriers with academic and government partners. Conclusions: Between May and December 2021, the GOTVax program reached over 2 million California residents and registered over 60,000 residents for COVID-19 vaccination. Public health campaigns may improve benefits from leveraging the expertise of community-trusted CBOs and universities by providing flexible infrastructure and funding, allowing CBOs to seamlessly tailor outreach most applicable to local minoritized communities.

description: Changes in regulations that would have allowed employers of H-2 temporary foreign agricultural workers to pay the Federal minimum wage instead of the higher adverse effect wage, would have lowered the estimated 1980 wage bill of H-2 employers by about 19 percent. The U.S. Department of Labor in consultation with the Department of Justice, operates the H-2 temporary foreign worker program. The non-wage costs incurred by employers of H-2 workers, primarily for housing, food, and transportation, was highest at $1,198 per worker on Virginia tobacco farms. Extending minimum wage coverage to all farms and hired farmworkers in the United States would have increased the 1980 farm wage bill by about 3.7 percent.

description: This study aimed to compare microscopic counting, culture, and quantitative or real-time PCR (qPCR) to quantify sulfate-reducing bacteria in environmental and engineered sludge samples. Four sets of primers that amplified the dsrA and apsA gene encoding the two key enzymes of the sulfate-reduction pathway were initially tested. qPCR standard curves were constructed using genomic DNA from an SRB suspension and dilutions of an enriched sulfate-reducing sludge. According to specificity and reproducibility, the DSR1F/RH3-dsr-R primer set ensured a good quantification based on dsrA gene amplification; however, it exhibited inconsistencies at low and high levels of SRB concentrations in environmental and sulfate-reducing sludge samples. Ultimately, we conducted a qPCR method normalized to dsrA gene copies, using a synthetic double-stranded DNA fragment as a calibrator. This method fulfilled all validation criteria and proved to be specific, accurate, and precise. The enumeration of metabolically active SRB populations through culture methods differed from dsrA gene copies but showed a plausible positive correlation. Conversely, microscopic counting had limitations due to distinguishing densely clustered organisms, impacting precision. Hence, this study proves that a qPCR-based method optimized with dsrA gene copies as a calibrator is a sensitive molecular tool for the absolute enumeration of SRB populations in engineered and environmental sludge samples.

description: A new cross-correlation synchrony index for neural activity is proposed. The index is based on the integration of the kernel estimation of the cross-correlation function. It is used to test for the dynamic synchronization levels of spontaneous neural activity under two induced brain states: sleep-like and awake-like. Two bootstrap resampling plans are proposed to approximate the distribution of the test statistics. The results of the first bootstrap method indicate that it is useful to discern significant differences in the synchronization dynamics of brain states characterized by a neural activity with low firing rate. The second bootstrap method is useful to unveil subtle differences in the synchronization levels of the awake-like state, depending on the activation pathway.

description: Over the past two decades, emerging fungal pathogens have been reported in numerous groups ranging from mammals to key crop species across the globe. To combat the rise of these fungal pathogens in industrial agriculture, fungicides have been developed and subsequently applied en masse. Despite their growing usage, research examining the effects of these anthropogenic contaminants on natural systems is severely limited compared to other major classes of pesticides. Of particular concern are their impacts on aquatic systems, which can be especially at risk due to their proximity to agriculture. Herein I used a tiered approach to assess the impacts of this class of pesticides on aquatic ecosystems using amphibians as model system. In the first chapter, I assessed the acute toxicity of two widely applied fungicides, pyraclostrobin and chlorothalonil, to six different species of amphibians commonly found in the Midwest. My results showed that these fungicides are very acutely toxic to several species of amphibians at levels within the expected environmental concentration (EEC). In the second chapter, I examined the impacts of long-term low-dose exposure of pyraclostrobin on the growth, development, and activity levels of three species of amphibians. Despite the acute toxicity of pyraclostrobin, sublethal effects of the fungicide were rather limited with only minor effect on growth and activity. In the third chapter, I investigated the effects of fungicide exposure on host-parasite interactions using trematodes and American Bullfrog tadpoles. I found that in all treatments pyraclostrobin increased parasite loads from ~3 to 8 times compared to control tadpoles. Additionally, parasite loads were approximately 2 times higher in tadpoles with the continued fungicide exposures compared to those tadpoles that were moved to fresh water following initial fungicide exposure. Finally, my fourth chapter investigated the impact of pyraclostrobin and chlorothalonil application regime on community-level interactions under semi-natural conditions. While chlorothalonil had limited effects on the community, I found that pyraclostrobin was acutely toxic to Gray Treefrogs at environmentally relevant concentrations and these effects were stronger with more frequent applications. Collectively, my research has demonstrated that fungicides can be acutely toxic to amphibians at EECs under laboratory and semi-natural conditions. Additionally, they have the potential to alter disease dynamics by increasing infection risk. Given our increasing usage of fungicides to control emerging fungal pathogens, a greater emphasis on understanding the environmental implications of this management strategy is needed to inform ecological risk assessments.

description: Objective: To determine the relation of COVID-19 symptoms to COVID-19 antibody positivity among unvaccinated pregnant women in low- and middle-income countries (LMIC). Design: COVID-19 infection status measured by antibody positivity at delivery was compared with the symptoms of COVID-19 in the current pregnancy in a prospective, observational cohort study in seven LMICs. Setting: The study was conducted among women in the Global Network for Women's and Children's Health's Maternal and Newborn Health Registry (MNHR), a prospective, population-based study in Kenya, Zambia, the Democratic Republic of the Congo (DRC), Bangladesh, Pakistan, India (Belagavi and Nagpur sites) and Guatemala. Population: Pregnant women enrolled in the ongoing pregnancy registry at study sites. Methods: Data on COVID-19 symptoms during the current pregnancy were collected by trained staff between October 2020 and June 2022. COVID-19 antibody testing was performed on samples collected at delivery. The relation between COVID-19 antibody positivity and symptoms was assessed using generalised linear models with a binomial distribution adjusting for site and symptoms. Main outcome measures: COVID-19 antibody status and symptoms of COVID-19 among pregnant women. Results: Among 19 218 non-vaccinated pregnant women who were evaluated, 14.1% of antibody-positive women had one or more symptoms compared with 13.4% in antibody-negative women. Overall, 85.3% of antibody-positive women reported no COVID-19 symptoms during the present pregnancy. Reported fever was significantly associated with antibody status (relative risk [RR] 1.10, 95% CI 1.03–11.18; P = 0.008). A multiple variable model adjusting for site and all eight symptoms during pregnancy showed similar results (RR 1.13, 95% CI 1.04–1.23; P = 0.012). None of the other symptoms was significantly related to antibody positivity. Conclusions: In a population-based cohort in LMICs, unvaccinated pregnant women who were antibody-positive had slightly more symptoms during their pregnancy and a small but significantly greater increase in fever. However, for prevalence studies, evaluating COVID-19-related symptoms does not appear to be useful in differentiating pregnant women who have had a COVID-19 infection.

description: Представляются результаты численных расчетов, направленных на моделирование нестационарного процесса формирования крупномасштабных вихрей на начальной стадии в тропосфере в окрестности внутритропической зоны конвергенции. Эти результаты ранее былиизложенывсерии работ, которые были опубликованы в разрозненных научных изданиях. В настоящей работе приводится обзор этих результатов и их обобщение. Обозреваемые результаты были получены не так давно при помощи региональной математической модели ветровой системы нижней атмосферы, разработанной ранее в Полярном геофизическом институте. Обозреваемые результаты моделирования показывают, что возникновение выпуклостей в очертаниях внутритропической зоны конвергенции может привести к зарождению различных крупномасштабных вихрей в нижней атмосфере, в частности, тропического циклона, пары циклонов, пары циклон-антициклон, а также трех циклонических вихрей. Обсуждается физический механизм, который приводит к формированию смоделированных крупномасштабных вихрей в окрестности внутритропической зоны конвергенции.

description: This study characterized variations in the methylation profile of mitochondrial DNA (mtDNA) during initial bovine embryo development and correlated the presence of methylation with mtDNA transcription. Bovine oocytes were obtained from abattoir ovaries and submitted to in vitro culture procedures. Oocytes and embryos were collected at various stages (immature oocyte, IM; mature oocyte, MII; zygote, ZY; 4-cells, 4C; 16-cells, 16C and blastocysts, BL). Total DNA (including mtDNA) was used for Whole Genome Enzymatic Methyl Sequencing and for quantification of mtDNA copy number. Extracted RNA was used for quantification of mitochondrial transcripts using Droplet Digital PCR. We selected ND6, CYTB, tRNA-Phe and tRNA-Gln based on their location in the mitochondrial genome, functionality and/or previous literature associating these regions with cytosine methylation. The number of mtDNA copies per oocyte/embryo was found to be similar, while methylation levels in mtDNA varied among stages. Higher total methylation levels were found mainly at 4C and 16C. In specific gene regions, higher methylation levels were also observed at 4C and 16C (ND6, CYTB and tRNA-Phe), as well as an inverse correlation with the quantity of transcripts for these regions. This is a first description of epigenetic changes occurring in mtDNA during early embryonic development. Our results indicate that methylation might regulate the mtDNA transcription at a local level, particularly around the time of embryonic genome activation.

description: In the 1980s, rural localities struggled to recover from the farm crisis and the national recession. Because of Federal and State cuts in social spending, rural communities had to rely more heavily on their own financial and organizational resources to initiate projects generating local jobs and income. Such grassroots efforts, called "self-development," were examined through a survey of 103 self-development projects across the United States, enriched by indepth study of eight successful and unsuccessful cases. The case studies suggest that the success of self-development efforts is in part related to contextual factors that the community cannot control. More importantly, however, community success in self-development is heavily dependent on its ability to overcome organizational problems. Communities enjoying the most success in their self-development efforts demonstrated leadership flexibility and adopted inclusive or group-focused approaches to community development.

description: TeV-blazars potentially heat the intergalactic medium (IGM) as their gamma rays interact with photons of the extragalactic background light to produce electron-positron pairs, which lose their kinetic energy to the surrounding medium through plasma instabilities. This results in a heating mechanism that is only weakly sensitive to the local density, and therefore approximately spatially uniform, naturally producing an inverted temperature-density relation in underdense regions. In this paper we go beyond the approximation of uniform heating and quantify the heating rate fluctuations due to the clustered distribution of blazars and how this impacts on the thermal history of the IGM. We analytically compute a filtering function that relates the heating rate fluctuations to the underlying dark matter density field. We implement it in the cosmological code GADGET-3 and perform large scale simulations to determine the impact of inhomogeneous heating. We show that, because of blazar clustering, blazar heating is inhomogeneous for z>= 2. At high redshift, the temperature-density relation shows an important scatter and presents a low temperature envelope of unheated regions, in particular at low densities and within voids. However, the median temperature of the IGM is close to that in the uniform case, albeit slightly lower at low redshift. We find that blazar heating is more complex than initially assumed and that the temperature-density relation is not unique. Our analytic model for the heating rate fluctuations couples well with large scale simulations and provides a cost-effective alternative to subgrid models.

description: This paper reports results from a large-scale randomized controlled trial assessing whether counter-stereotypical messaging and partisan cues can induce people to get COVID-19 vaccines. The study used a 27-s video compilation of Donald Trump's comments about the vaccine from Fox News interviews and presented the video to millions of U.S. YouTube users through a $100,000 advertising campaign in October 2021. Results indicate that the number of vaccines increased in the average treated county by 103 (with a one-tailed P value of 0.097). Based on this average treatment effect and totaling across our 1014 treated counties, the total estimated effect was 104,036 vaccines.

description: Optical Feshbach resonances (OFRs) have generated significant experimental interest in recent years. These resonances are promising for many-body physics experiments, yet the practical application of OFRs has been limited. The theory of OFRs has been based on an approximate model that fails in important detuning regimes, and the incomplete theoretical understanding of this effect has hindered OFR experiments. We present the most complete theoretical treatment of OFRs to date, demonstrating important characteristics that must be considered in OFR experiments and comparing OFRs to the well-studied case of magnetic Feshbach resonances. We also present a comprehensive treatment of the approximate OFR model, including a study of the range of validity for this model. Finally, we derive experimentally useful expressions that can be applied to real experimental data to extract important information about the resonance structure of colliding atoms.

description: Particle size measurement is crucial in various applications, be it sizing droplets in inkjet printing or respiratory events, tracking particulate ejection in hypersonic impacts or detecting floating target markers in free-surface flows. Such systems are characterised by extracting quantitative information like size, position, velocity and number density of the dispersed particles, which is typically non-trivial. The existing methods like phase Doppler or digital holography offer precise estimates at the expense of complicated systems, demanding significant expertise. We present a novel volumetric measurement approach for estimating the size and position of dispersed spherical particles that utilises a unique ‘Depth from Defocus’ (DFD) technique with a single camera. The calibration-free sizing enables in situ examination of hard to measure systems, including naturally occurring phenomena like pathogenic aerosols, pollen dispersion or raindrops. The efficacy of the technique is demonstrated for diverse sparse dispersions, including dots, glass beads and spray droplets. The simple optical configuration and semi-autonomous calibration procedure make the method readily deployable and accessible, with a scope of applicability across vast research horizons.
