A Quantitative Metric for Organic Radical Persistence Using Thermodynamic and Kinetic Features
Authors: Sowndarya S. V. Shree , St. John Peter , Paton Robert
Published: May 2021

Long-lived organic radicals are promising candidates for the development of high-performance energy solutions such as organic redox batteries, transistors, and light-emitting diodes. However, “stable” organic radicals that remain unreactive for an extended time and that can be stored and handled under ambient conditions are rare. A necessary but not sufficient condition for organic radical stability is the presence of thermodynamic stabilization, such as conjugation with an adjacent p-bond or lone-pair, or hyperconjugation with a s-bond. However, thermodynamic factors alone do not result in radicals with extended lifetimes: many resonance-stabilized radicals are transient species that exist for less than a millisecond. Kinetic stabilization is also necessary for persistence, such as steric effects that inhibit radical dimerization or reaction with solvent molecules. We describe a quantitative approach to map organic radical stability, using molecular descriptors designed to capture thermodynamic and kinetic considerations. The comparison of an extensive dataset of quantum chemical calculations of organic radicals with experimentally-known stable radical species reveals a region of this feature space where long-lived radicals are located. These descriptors, based upon maximum spin density and buried volume are combined into a single metric, the Radical Stability Score, that outperforms thermodynamic scales based on bond dissociation enthalpies in identifying remarkably long-lived radicals. This provides an objective and accessible metric for used in future molecular design and optimization campaigns. We demonstrate this approach in identifying Pareto-optimal candidates for stable organic radicals.

Alternativas al desarrollo y otras legalidades: los derechos de la Naturaleza
Authors: Álvarez-Lugo Yésica
Published: May 2021

La aparición del posdesarrollo ha supuesto un punto de inflexión en el devenir de los estudios sobre desarrollo. Sin embargo, el corpus bibliográfico que da forma a esta corriente de pensamiento adolece de una escasa integración de las cuestiones jurídicas en el análisis crítico del discurso desarrollista, limitadas a las referencias al pluralismo jurídico. En este sentido, parece oportuno evidenciar la importancia de profundizar en el estudio de las relaciones entre las alternativas al desarrollo y el campo jurídico, así como llamar la atención sobre la necesidad de matizar qué tipo de pluralismo jurídico es defendido por el posdesarrollo. Finalmente, presentaremos los derechos de la Naturaleza reconocidos en la Constitución ecuatoriana de 2008 como una oportunidad para ir avanzando hacia otro Derecho que respalde las alternativas al desarrollo.

Authors:   Bauman Moscow State Technical University, the Kaluga Branch, IGNATKIN IVAN Yu.
Published: May 2021

The paper discusses the results of comparative tests of the period of tap resistance in various technological environments. The workpieces were processed in the medium of industrial oil I-30 with using a 10 and 20 percent solution of the metal-coating additive “Valena SV” in the same oil. The tests were performed on M10×1 taps made of high-speed steel of the R6M5 brand during the production of through threaded holes in samples made of steel of the Steel 40X brand. The cutting speed varied from 5.7 to 11.1 m/min at the rotary speed of the tool ranging between 180 and 355 rpm. Based on the experimental material, a regression model of the relationship between the relative wear resistance and the additive concentration, and cutting speed has been determined. The author has evaluated the model adequacy and the convergence of the experimental and calculated data. It has been found that at a cutting speed of 11.1 m/min and an additive concentration of 20%, the relative wear resistance of the taps increased by 3.1 times. The results obtained testify to the eff ectiveness of the composition and confi rm the hypothesis of an increase in the wear resistance of the taps in the medium of metal-plating lubricating-and-cooling liquids.

The production of high-quality repaired engines is possible only with the right selection of technological equipment. The issues of the processing quality on honing machines rank first in the repair production, since the reliability of engines depends on the processing quality of cylinder liners. It is revealed that for a clear understanding of the feasibility of using old and choosing new technological equipment, it is necessary to evaluate it from the standpoint of an integral quality indicator. As a basic model for assessing the quality of technological equipment, use is made of the cost method. According to it, the cost index of quality as the value inverse to the integral indicator of product quality is formed for evaluating machines. It is determined by the value of the unit cost of processing one part calculated in cost form by groups of resource intensity indicators multiplied by the corresponding resource prices. Each cost group is the product of the resource price by its specific consumption in physical terms, resulting in a cost index of quality. For honing machines used for processing cylinder liners, a relationship was determined to analyze the cost index of quality. This index includes four basic elements – the indicators of material intensity, labor intensity, energy intensity of machinery and the material intensity of the inputs used in the technological process. The evaluation of the quality of machines has revealed that purchasing new equipment is economically feasible as technical and economic level of new machines exceeds the base level due to increased productivity, reduced energy consumption and unit cost. It is most advisable to use the ROBBI SET150-L machine (Italy) from among the new ones, since its integral quality indicator is significantly higher than its analogues. From among the old ones, NAGEL VS8-50 (Germany) should be recommended, while domestic machines should be replaced due to their low efficiency.

Authors: L Klimek , J Hagemann , I Casper , T Huppertz , A Bedbrook , J Bousquet
Published: May 2021

Background: Chronic rhinosinusitis (CRS) is a heterogeneous and multifactorial inflammatory disease of the nasal and paranasal mucosa. To date, no internationally standardized uniform classification has been developed for this disease. Usually, a phenotype classification according to CRS with (CRSwNP) and without (CRSsNP) polyposis is performed. However, through a variety of studies, it has been shown that even within these phenotypes, different endotypes of CRS exist, each with a different underlying inflammatory pathophysiology. In this mini-review, we aim to outline the essential immunological processes in CRSwNP and to highlight the modern therapeutic options with biologics derived from this disease. Methods: Current knowledge on the immunological and molecular processes of CRS, especially CRSwNP, was compiled by means of a structured literature review. Medline, PubMed, national/international trial and guideline registries as well as the Cochrane Library were all searched. Results: Based on the current literature, the different immunological processes involved in CRS and nasal polyps were elaborated. Current studies on the therapy of eosinophilic diseases such as asthma and polyposis are presented and their results discussed. Conclusion: Understanding the immunological basis of CRSwNP may help to develop new personalized therapeutic approaches using biologics. Currently, 2 biologics (dupilumab, omalizumab) have been approved for the therapy of CRSwNP (polyposis nasi) in Europe.
Role of toll-like receptors and their ligands in adipocyte secretion
Authors: A Mishra , AV Shestopalov , AM Gaponov , IA Alexandrov , SA Roumiantsev
Published: May 2021

Background: Adipose tissue is one of the main sites of energy homeostasis that regulates whole body metabolism with the help of adipokines. Disruption in its proper functioning results in adipose tissue remodeling (primarily hypertrophy and hyperplasia) which directly influences the secretion of said adipokines. Obesity characterized as chronic low-grade inflammation of the adipose tissue is one such condition that has far reaching effects on whole body metabolism. Inflammation in turn results in immune cells infiltrating into the tissue and further promoting adipocyte dysfunction. Purpose: In our study we explored this adipose tissue-innate immunity axis by differentiating adipose tissue derived stem cells (ADSCs) into white and beige adipocytes. We further stimulated our cultures with lipopolysaccharide (LPS), flagellin, or meteorin-like, glial cell differentiation regulator (METRNL) to trigger an inflammatory response. We then evaluated Toll-like receptor (TLR) mRNA expression and secretion of interleukin (IL-6), interleukin-8 (IL-8), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) in these cultures. Results: We found that TLR2 is the highest expressed receptor in adipocytes. Further, LPS and METRNL are strong activators of TLR2 in white and beigeBMP7(-) adipocytes. TLR4 was not significantly expressed in any of our cultures despite LPS stimulation. TLR9 expression is upregulated in ADSCs upon LPS and METRNL stimulation. IL-6 and IL-8 secretion is increased upon LPS stimulation in white adipocytes. METRNL activates both IL-6 and IL-8 expression in adipocyte cultures. Lastly, BDNF and NGF is secreted by all adipocyte cultures with beigeBMP7(-) and beigeBMP7(+) secreting slightly higher amounts in comparison to white adipocytes. Conclusion: ADSCs and adipocytes alike are capable of expressing TLRs, but white adipocytes remain the highest expressing in both control and stimulated cultures. TLR2 is highly expressed in white and beige adipocytes whereas TLR4 showed no significant expression. LPS and METRNL trigger IL-6 and IL-8 secretion in adipocytes. Products of white adipocyte “browning” are capable of secreting higher amounts of BDNF and NGF in comparison to white adipocytes.
To What Cost to its Continental Hegemonic Standpoint: Making Sense of South Africa’s Xenophobia Conundrum Post Democratization
Authors: Mlambo Daniel Nkosinathi , Mlambo Victor H.
Published: May 2021

From the 1940s, a period where the National Party (NP) came into power and destabilized African and Southern Africa’s political dynamics, South Africa became a pariah state and isolated from both the African and African political realms and, to some extent, global spectrum(s). The domestic political transition period (1990-1994) from apartheid to democracy further changed Pretoria’s continental political stance. After the first-ever democratic elections in 1994, where the African National Congress (ANC) was victorious, South Africa was regarded as a regional and continental hegemon capable of re-uniting itself with continental and global politics and importantly uniting African states because of its relatively robust economy. However, the demise of apartheid brought immense opportunities for other African migrants to come and settle in South Africa for diverse reasons and bring a new enemy in xenophobia. Post-1994, xenophobia has rattled South Africa driven (albeit not entirely) by escalating domestic social ills and foreign nationals often being blamed for this. Using a qualitative methodology supplemented by secondary data, this article ponders xenophobia in post-democratization South Africa and what setbacks this has had on its hegemonic standpoint in Africa post the apartheid era.
Acquisition of a spatial navigation task in the padding pool induces an increase of GABA level in the hippocampus of Swiss mice
Authors: Isabela Cristina Romano Sena  , Angela Maria Ribeiro
Published: May 2021

The balance between excitatory and inhibitory glutamatergic and GABAergic systems, respectively, is crucial for the maintenance of complex cognitive functions such as learning. Using Swiss mice as experimental model, the aims of the present study were to evaluate cognitive performance in a shallow water maze (SWM) and the effects of training in this spatial navigation task on hippocampal GABA and glutamate levels. In addition, correlations between neurochemical and behavioural data, and between glutamate and GABA levels were assessed. Forty-six three-month-old mice were divided into three groups: Learning, n=18: animals submitted to the SWM task; Active, n=14: animals exposed to the SWM, without the demand of performing a cognitive task and Control, n=14: the animals were kept in the vivarium without contact with the SWM. There was significant training effect indicating that the Learning group animals have learned the task. Regarding neurochemical data, the findings of the present work show for the first time that the task learning process in SWM has a significant effect on GABA levels in the hippocampus. The relationship between the two neurotransmitters, observed in the control animals, was adjusted by a significant increase in hippocampal GABA levels caused by the spatial training performed by the animals from the Learning group. However, the relationship observed in control condition is disrupted by a subsequent exposure to the maze in the absence of a spatial cognitive demand, as was the case of the Active group. These data open new perspectives to explore the involvement of the inhibitory and excitatory systems in the molecular mechanisms associated with different types and steps of learning processes.

Published: May 2021

Liver diseases are a major cause of mortality and morbidity in developing countries. This study aims at determining the hepatotoxicity effects of methanolic-extracts of Gmelina arborea leaves at different concentrations on liver marker enzymes in wistar rats. The experiment was laid out in a complete randomized design (CRD). Fresh leaves of Gmelina arborea from the school environments was collected, dried, grinded and extracted using muslin cloth and methanol. The extract was then placed in the oven at about 38oC for dryness. The extract was administered to five groups of wistar rats orally and twice daily for 21 days at doses of 1000mg/kg, 500mg/kg, 250mg/kg, 125mg/kg and group one control group (wasn’t administered this extract). At the end of every week (7 days) the blood samples were collected through ocular puncture, and biochemical analysis of Serum test (Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Alkaline phosphatase (ALP) , Total bilirubin (TB) and Conjugated bilirubin (CB) were estimated. There was no mortality observed as a result of administration of this leave extract. Methanol extract of Gmelina arborea did not produce significant differences in the body weight, organ weights and feeding habits between control and treated animals. Pathologically, neither gross abnormalities nor histopathological changes were observed. Methanol extract of Gmelina arborea was found safe in acute and repeated dose toxicity study when tested in wistar rat.

Authors: Godwin Chinedu Uloneme
Published: May 2021

Background: The plant, Corchorus olitorius is consumed by many tribes and cultures for both nutritional and therapeutic purposes. Purpose: The study was therefore designed to investigate, evaluate and unravel the possible effects of the plant extract on the sperm count and sperm motility. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 g separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorius; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the rats were sacrificed and the testes and accompanying epididymis harvested for investigations using standard laboratory standards. Results: Surprisingly, semen analysis showed that group B, C and D rats had an improved and increased sperm motility rate over group (A). Again, there was a pronounced significant increase in the average sperm count of the rats treated with varying doses of Corchorus olitorius leaf extract over that of the control group, a development that appeared to be dose dependent.

Published: May 2021

Objective Anxiety and depression and sociodemographic factors such as age, gender, education level, income, and marital status among people with panic disorder (PD) are associated with functional impairment in the areas of work, social, and family. Although both PD-specific scales such as the Panic Disorder Severity Scale (PDSS) and Anxiety Sensitivity Inventory-Revised (ASI-R) and early trauma have been investigated, their relationship with functional impairment in PD patients has not been clarified.Methods This study included 267 PD patients. The PDSS, Beck Depression Inventory (BDI), ASI-R, and Early Trauma Inventory were used. Pearson’s correlation and multiple linear regression analyses were performed. The Sheehan Disability Scale (SDS) was administered to assess the functional impairment level in PD patients.Results Our findings showed that high levels of PDSS, BDI, and ASI-R were significantly correlated with the functional impairment among PD patients. Multiple regression analyses showed that PDSS, BDI, and ASI-R can predict the functional impairment levels, and PDSS and ASI-R were significantly associated with lost and underproductive days in PD patients.Conclusion Panic-specific symptoms, depression, and AS are associated with functional impairment level in PD patients. Elevated symptom severity can play a role by affecting productivity and daily responsibilities in PD patients.
Congresos de amor Entrevistas sobre los italianos y el sexo, 1963
Authors: Merlo Alessandra
Published: May 2021

En el verano de 1963 Pier Paolo Pasolini recorre Italia con un micrófono en la mano. En las plazas de los pueblos, en las playas del norte y del sur, en las discotecas y en los trenes entrevista a la gente y le pregunta sobre el sexo: qué papel tiene en su vida, si para los hombres es igual que para las mujeres, si el matrimonio resuelve o satisface la sexualidad de cada uno. En sus preguntas toca los temas de la virginidad, el machismo, la diversidad, el matrimonio y la prostitución. Lo que nace de ese viaje es un documental, Comizi d’amore, que reflexiona sobre los límites y los tabúes de una sociedad, pero también sobre las formas de hablar de algo íntimo y colectivo a la vez, algo que a veces es censurado, a veces reivindicado, en muchos casos disimulado detrás de lugares comunes. El resultado es una radiografía poética de su entorno que logra dar voz a gente anónima junto con personajes conocidos, como Giuseppe Ungaretti, Alberto Moravia, Camilla Cederna y Oriana Fallaci, entre otros. La película circuló muy poco en Italia y todavía menos en el mundo de habla hispana, a pesar del valor social, cultural y político del experimento de Pasolini. Son justamente esos valores los que la hacen, hoy, todavía más interesante de lo que fue en su momento. Estas entrevistas muestran en efecto el atrevimiento, la libertad de nombrar y también el conservadurismo de una época; pero sobre todo su valor está en preguntarnos dónde estamos nosotros frente a la sexualidad y frente a los temas que en ese ámbito todavía limitan y dividen, contraponen y estigmatizan. ¿Cómo le contestaríamos, nosotros y en nuestra época, a Pasolini? Así, esta edición presenta por primera vez la traducción al español de las entrevistas y del primer argumento (Cien pares de bueyes), con unas fotos de Angelo Novi, que acompañó a Pasolini en su correría por Italia.

Published: May 2021

This study has been designed to examine pre-service teachers' metaphorical perceptions of physical education and sports. In this study, phenomenology, one of the qualitative research designs, was used. The study group consists of 60 pre-service teachers studying at the Department of Physical Education and Sports Teaching at Şırnak University during the 2020-2021 academic year. Research data were obtained from the statements of students who were asked to complete the sentence "Physical Education and sports are like … for me because ... ". Research data were analysed using the content analysis method. The analysis of the data consists of stages including classification, elimination, category development, validity and reliability tests, and interpretation of the metaphors obtained in the study, respectively. Six categories were created in this study in which the metaphorical perceptions of pre-service teachers of the concept of physical education and sports were examined. Categories created for physical education and sports were healthy/quality life, life/lifestyle, freedom/entertainment, indispensable/sine qua non, source of peace/love, and development. As a result, it was determined that pre-service teachers have positive opinions about physical education and sports and have no negative judgment.

Se você nasceu no Paraná na década de 1990, provavelmente cresceu ouvindo histórias sobre as Bruxas de Guaratuba. Celina e Beatriz Abagge foram presas em julho de 1992, acusadas de sacrificarem um menino de apenas 7 anos de idade durante um ritual de bruxaria, e permaneceram presas por mais de 6 anos. Em 1998, o caso resultou no júri mais longo da história do judiciário brasileiro. Mas, e se te contarmos que de bruxas elas não têm nada? Que, apesar de terem confessado o crime, Celina e Beatriz foram absolvidas depois de julgadas por exaustivos 34 dias? Desde 2018, esses nomes voltaram à boca do povo por conta do sucesso do podcast “O Caso Evandro” – produzido e narrado pelo jornalista Ivan Mizanzuk, que prefaciou esta obra –, e a acusação e a prisão das Abagge voltaram a ser debatidas. Neste livro, você vai descobrir os detalhes da história, contados pelas próprias “bruxas”.
DISLEXIA: das causas e consequências ao diagnóstico e intervenções
Authors: Gonçalves Araújo Ana Claudia
Published: May 2021

A Dislexia, suas causas, consequências, o diagnóstico e as possíveis intervenções são tema deste estudo. A metodologia utilizada é uma revisão bibliográfica, focada em livros sobre a temática, percorrendo um período na história da Dislexia até os dias atuais com o uso das Tecnologias da Informação e Comunicação (TIC). Objetivou-se investigar sua origem, sua definição, o que ocasiona na vida do disléxico, como realizar um diagnóstico até sugestões para intervenções escolares. Concluímos que apesar de ter sido descoberta há muitos anos, há ainda bastante desconhecimento por parte da escola, professores e familiares. Sendo, portanto, necessária mais divulgação acadêmicocientífica para que essas pessoas sofram menos seus efeitos.

Published: May 2021

U radu autor analizira način na koji se Državno vijeće u Francuskoj bavilo zdravljem u okolnostima izvanrednih kriza. Iako su sudske metode i sredstva njegove kontrole blisko povezane s povijesti i kulturom zemlje autor je pozivajući se na Pascala (''Istina ispod Pirineja je negdje drugdje pogreška'') uvjeren da ova institucija podržava ključnu vrlinu opće pravednosti. Također je uvjeren da unatoč svih razlika koje nas dijele, moramo učiti jedni od drugih, što i podiže vrijednost bilateralne suradnje.

The role of love in public sector leadership in Slovenia
Authors: Pličanič Senko
Published: May 2021

The article discusses the importance of self-love in public sector leadership and public sector employees engagement. Given the importance of leadership in our civilisation, the almost complete absence of self-love in leaders is especially detrimental to the organisations they lead and their employees. This is especially important in the public sector–due to the importance of the goods and services it provides, and the fact that it does so with the taxpayers’ money. Leaders who love themselves and lead with love, know how to step into the employees’ shoes, understand them; know how to find the best in each one of them and encourage the development of that aspect; they are sincere and warm; know how to listen to employees and impress them; they are respectful of them; they inspire a sense of security and confidence; spread positive energy and know how to make decisions.
Also, the connection between self-love and sustainable development social model is discussed. Due to the unilateral orientation of our civilisation toward material development, individuals have almost eliminated the pursuit of spiritual development from their lives. However, love and happiness can only be achieved with the balance of both. The integral principle of sustainable development, which, in addition to economic growth, encompasses spiritual growth, is a model that offers us a way out of our (bad) state–in the world and in Slovenia. Of particular importance–primarily because of the long absence–is the spiritual side. People need to reintroduce it into their lives. In doing so, the state and the law should be “utilised”, and to set as their main task the provision of conditions for (in addition to economic) spiritual growth and thus love and happiness.
Pervasiveness of Communication Disorders and Fatigue in Stroke Patients: A Systematic Scoping Review
Authors: Riley Ellyn , Hart Emily , Preston Jonathan , Wu Ying , Ashaie Sameer
Published: May 2021

After a stroke, it is highly likely that an individual will experience substantial fatigue that can significantly affect recovery and function; stroke survivors also have more than a 50% chance of having at least one communication disorder. Current reviews of post-stroke fatigue have not provided evidence focused on communication disorders or the potential influence they may have on post-stroke fatigue and related recovery. The aim of this review was to determine how communication disorders are represented in post-stroke fatigue research and to catalogue methods used to identify communication disorders and measure fatigue. A systematic scoping review was conducted to identify studies measuring post-stroke fatigue. To identify these studies, a comprehensive literature search was conducted using relevant databases and grey literature sources, followed by several stages of review that adhered to PRISMA guidelines. We evaluated these studies using pre-established eligibility criteria and extracted data regarding the inclusion/exclusion of persons with communication disorders and the assessment methods used. The scoping review analysis was conducted on 161 studies. Of these, 41 (26%) excluded all communication disorders, 71 (44%) excluded severe communication disorders, and 49 (30%) included participants with communication disorders. Of the 120 studies that did not explicitly exclude all communication disorders, only 34 were confirmed to report data from at least one person with a communication disorder. Further, only 5 studies reported data that could be used to determine a relationship between these co-morbidities. Persons with communication disorders are underrepresented in post-stroke fatigue research and very few studies have examined the relationship between post-stroke fatigue and communication disorders, limiting conclusions that can be drawn. This is problematic because medical professionals relying on this evidence to guide clinical practice are likely to be treating individuals with co-occurring fatigue and communication disorders and the current research does not provide enough information about the potential impact of fatigue on communication disorders or vice versa. To bridge this gap, we suggest methods of assessment that could provide ways to more accurately 1) reflect the real patient population in post-stroke fatigue studies, and 2) measure and document fatigue in post-stroke communication disorder studies.

Objectives: Transmission routes for SARS-CoV2, include fomites/ surfaces, ballistic droplets and aerosols/airborne. Current infection prevention and control guidance in the UK does not make strong recommendations against the airborne aerosol route perceiving the other routes to be more relevant. Methods: We conducted a single centre retrospective observational study before and after implementation of enhanced respiratory protection with FFP3 respirators. Results: There was a 59% reduction in staff absence due to Covid-19 infection from the ten weeks prior vs four weeks post implementation of FFP3 respirators (3.2 vs 1.3 staff off sick per week respectively). This corresponded with a 65% reduction in total days absent from work for the same periods (18 vs 6.25 sick days per week). Conclusions: Although causation cannot be proven from this study, significant decreases in staff sickness from Covid-19 were observed following FFP3 implementation.Keywords: Respiratory protective equipment, COVID-19, SARS-CoV2, FFP3, FRSM, personal protective equipment

Field evidence for disequilibrium dynamics in preserved fluvial cross-strata: A record of discharge variability or morphodynamic hierarchy?
Authors: Lyster Sinead , Whittaker Alexander , Hajek Elizabeth , Ganti Vamsi
Published: May 2021

Bedforms preserved in the rock record can provide detailed information on the morphologies and hydrodynamics of ancient fluvial systems on Earth and other planets. Existing process–product relations for bedform preservation assume that fluvial cross strata reflect conditions under which bedforms were equilibrated with the prevailing flow, i.e., steady-state conditions. However, recent theoretical and experimental observations indicate that enhanced bedform preservation can occur in non-steady state, or disequilibrium, conditions, and it is currently unclear how prevalent disequilibrium dynamics are in preserved fluvial strata at outcrop scale. Here we explore whether steady-state assumptions are appropriate for ancient fluvial systems by evaluating the nature of bedform preservation in well studied fluvial deposits of three Late Cretaceous (Turonian and Campanian) geologic formations in central Utah, USA: the Blackhawk Formation, Castlegate Sandstone, and Ferron Sandstone. In the field, we made systematic measurements of dune-scale cross-strata to quantify the extent to which preserved cross-sets reflect dune preservation in steady-state conditions. Across the three formations, consistently low coefficients of variation in preserved cross-set thicknesses of 0.25–0.5 are inconsistent with bedform preservation in steady-state conditions, and instead point to fluvial systems in which enhanced bedform preservation occurred in disequilibrium conditions.Enhanced bedform preservation in dune-scale cross-stratification can be explained by two independent hypotheses: the effect of flashy flood hydrographs on bedform preservation (flood hypothesis) or bedform preservation in the presence of larger migrating barforms (hierarchy hypothesis). We estimated bedform turnover timescales to quantitatively assess these competing hypotheses and contextualize their implications. Under the flood hypothesis, field measurements are consistent with enhanced bedform preservation driven by flashy flood hydrographs with flood durations ranging on the order of hours to a few days, which are consistent with perennial fluvial systems subject to heavy rains and tropical storms. Alternatively, under the hierarchy hypothesis, field measurements are consistent with bedform climb angles that range from 10−2 to 10−1, reflecting rapid bar migration. Our work provides a novel way of investigating fluvial discharge variability in the geologic past, and we outline the potential next steps to disentangle the relative controls of flow variability and hierarchy in controlling bedform preservation in ancient fluvial systems.
