Interaction of strategic management processes and achieved corporate profitability: Evidence from Croatia
Authors: Vinšalek-Stipić Valentina
Published: May 2021

Strategic management can be said to have evolved over time and will continue to evolve. In order for companies to be more successful in their operations, they need a methodological approach to developing a strategic plan. Strategy implementation is a complex process because it is a consequence of complex relationships. In accordance with the above, an empirical study was conducted on a sample of 53 companies in the Republic of Croatia. The subject and goal of the research was to scientifically determine the importance of adopting and implementing long-term strategic plans. The main results of the research are that the degree of implementation of the strategy is not significantly related to the indicators of net profit margin (ROS 0.164) and return on equity (ROE 0.216), while it is partially related to the indicator of earnings strength (TSZ 0.304) but is significant for a successful business. The implementation of the research revealed that strategic planning is an extremely important and significant factor for stable growth and development of the company. The implementation of the strategy has an important contribution to the successful operation of the company.
Eosinophilic esophagitis: A potential complication of sublingual immunotherapy
Authors: Knežević Snežana , Dugalić Branimir
Published: May 2021

Introduction. Eosinophilic esophagitis (EoE) represents chronic, a local immune-mediated disease with symptoms of esophageal dysfunction and histologically eosinophil-predominant inflammation and requires immediate endoscopy. Male gender is a strong risk factor. Case report. We presented a case of a 25-year-old young man with a history of allergic rhino-conjunctivitis, asthma, and intermittent severe feeding disturbance. The patient had begun sublingual immunotherapy therapy, containing specific soluble allergens for ambrosia. Six weeks after starting the ambrosia sublingual immunotherapy he developed burning epigastric pain, dysphagia, and odynophagia. Six days later, he was admitted to an emergency department due to choking on a solid of food. Esophageal histopathological findings were in favor of EoE. Sublingual immunotherapy was discontinued. He feels well now. Conclusion. The majority of cases of Eosinophilic esophagitis are diagnosed in spring or fall, 1-2 months following the peak of pollen season. Dysphagia, chest pain, food sticking, and bolus obstruction are the most common symptoms. Endoscopic findings are Schatzki ring, edema, exudates, furrows, and strictures. Six biopsies should be taken from areas with endoscopic mucosal abnormalities, and infiltration of eosinophils (more than 15 eosinophils/HRI) (HRI - high resolution imaging) is necessary for the diagnosis confirmation. Treatment options are proton pump inhibitors - oral dispersible tablets of budesonide or fluticasone propionate, an elimination diet. Sublingual immunotherapy should be discontinued. Family physicians should be aware of this complication in evaluating patients with dysphagia.

Published: May 2021

ResumenLa presente investigación se realiza en el campo de las lesiones en el deporte con el propósito de identificar su relación con las habilidades psicológicas de ejecución deportiva. Se realizó un estudio de 21 deportistas femeninas de alto rendimiento integrantes del equipo nacional cubano de Softbol a las que se les aplicó el Cuestionario de Aspectos Deportivos y Lesiones y el Inventario Psicológico de Ejecución Deportiva. Los resultados muestran un alto porcentaje de lesiones en las deportistas, cuyo perfil psicológico grupal se encuentra configurado por elevados niveles de Autoconfianza, Nivel Motivacional, Control de Afrontamiento Positivo y Control de la Actitud. Además se evidencia que las deportistas con menor autoconfianza, control emocional y de la actitud se han lesionado en más oportunidades y han presentado lesiones de mayor gravedad respectivamente. También se muestra que dentro del grupo de deportistas con antecedentes de lesiones existen diferencias estadísticamente significativas, ya que poseen valores medios inferiores de autoconfianza y control de afrontamiento negativo las que más lesiones han sufrido. Se discuten los resultados.AbstractThe present research is framed in the field of sports inju­ries, having as object of study its relation with the psycho­logical skills of sports performance. A study of 21 high-performance female athletes members of the Cuban na­tional softball team was carried out, to which the Sports Aspects and Injuries Questionnaire and the Psychological Inventory of Sports Execution were applied. The results show a high percentage of injuries in athletes, whose group psychological profile is configured by high levels of Self-Confidence, Motivational Level, Positive Coping Control and Attitude Control. It is also evidenced that ath­letes with less self-confidence, emotional control and atti­tude have been injured in more opportunities and have pre­sented more serious injuries respectively. It is also shown that within the group of athletes with a history of injuries there are statistically significant differences, since they have lower average values of self-confidence and negative coping control those who have suffered the most injuries. The results are discussed.

Toward Numerical VPP with the Full Coupling of Aerodynamic and Hydrodynamic Solvers for ACC Yachts
Authors: Jacquin Erwan , Roux Yann , Allessandrini Bertrand
Published: May 2021

The classical approach of Velocity Prediction Program is to find the balance of Hydrodynamic and aerodynamic sensors acting on the yacht to determine sailing conditions and associated performance. Usually, this approach is based on the data given by towing tank, wind tunnel or numerical computations. We present in this paper the unsteady coupling between an hydrodynamic RANSE with free surface solver and a panel aerodynamic solver that allow to directly find the sailing condition of the yacht, and its performances, compute bay solving the six degrees of freedom motion equations of the ship in the hydrodynamic solver. The main advantage of this computational method is the decrease of numerical evaluation, compared to the classical interpolation approach to determine performances of a hull, and to directly rank several hills in the term of performances and not only in the term of drag in fixed conditions. Further, improvements will allow to simulate unsteady maneuvering of sailing yacht, and focus will for example on restart behavior after tacking, dynamic behavior in waves.
Experimental Methods To Evaluate Underwater Appendages
Authors: Ranzenbach Robert , Zahn Mathew
Published: May 2021

The Glenn L. Martin Wind Tunnel (GLMWT) has developed specialized investigative techniques to evaluate underwater appendages for sailing yachts that have been continuously improved through practice by GLMWT staff. These specialized techniques are required to obtain the best possible differential evaluation of appendage designs that commonly have differences in drag of a fraction of 1percent. The general methods of study will be described and a representative set of results is presented, which highlights that the minimum drag appendage solution is not necessarily the optimal set of appendages for an America’s Cup yacht.

PCLINES, A Parametric Lines Development Program for the Home Computer
Authors: Martin David E.
Published: May 2021

An Excel© spreadsheet lines development program has been written for a home computer and is available to conference attendees. The program utilizes B-Spline parametric formulations for planar curve definition of the traditional hull lines: body, waterlines and buttocks. The user establishes the basic hull outline, in BSpline curves, by inputting bow and stern overhangs, freeboard at selected points, the draft of the canoe body at selected points, the beam on deck at selected points, and the maximum beam at the waterline. By judicious selections the user will see the resulting hull outline in profile and plan views, and can easily adjust these inputs to gain the desired hull outline. The user works with actual points on the hull rather than B-Spline vertices.

The hull lines are then developed by the Excel program which establishes the hull form defined by the above outlines and satisfying inputs of the conventional hull form parameters: Center of Buoyancy, (Lcb) Center of Floatation, (Lcf) Prismatic Coefficient, (Cp), Maximum Section Coefficient, (Cm) and the Water-plane Coefficient, (Cwp). The lines development is accomplished in two steps.

First, the user employs the Excel Solver to establish a waterline, and Sectional Area curve that satisfy the above parameters. The program accomplishes this by varying the draft at stations two and eight, which adjusts the shape of the center-plane curve without changing the draft, Tc. The solver ensures a “fair” waterline by minimizing the “bending” criterion of the waterline: that is, by minimizing the sum of the squares of d2y/du2 and d2x/du2. Here, y and x are defined by B-Spline formulations in the parameter “u”. The vertices of the B-Spline functions are varied by the Excel Solver to find the minimum bending criterion.

Second, with the Section Area and waterline beam established for each station, the program establishes the shape of each station body curve which satisfies the section area, draft, freeboard and beams on deck and waterline. Fairness is again established by minimizing the “bending” criterion.

Since there are no section areas for stations 10 and the transom, a scheme for constructing a transomgeometrically similar to station 9.5 is provided. Station 10 is established by fairing to the transom.

The program can establish a round bottom hull in about a minute and a half after the input parameters are entered. It is essential however that the hull form parameters be selected judiciously. Clearly Lcb and Lcf must be compatible, and the hull outline must be reasonable in order to gain a fair hull. In this regard the user is provided with automatic input of six different hull shapes that provide good starting points for a design effort. Thus, in a matter of minutes the user can examine an alternate hull shape while keeping selected hull form parameters constant.
An Aerodynamic Analysis of the U.S. Brig Niagara
Authors: Lasher William C. , Musho Terrence D. , McKee Kent C. , Rybka Walter
Published: May 2021

A CFD-based model has been developed for predicting the aerodynamic forces on the rig and sails of the U.S. Brig Niagara. Wind tunnel tests and full-scale experiments were performed to validate the model. The model was then used to predict both the optimum sail trim for various points of sail, as well as the heel angle for different wind speeds. The results show that the optimum bracing (or trim) angle for square sails when sailing off the wind differs significantly from conventional wisdom. The stability analysis shows that the maximum heeling moment occurs when the apparent wind is approximately 80° from the bow, and that with a typical heavy weather sail configuration Niagara would be at risk of capsize in about 40 knots of wind. These results are useful for learning about square rig sailing as well as providing guidance to the Niagara’s officers regarding survivability of the ship.

Ce thème peu débattu par la littérature traitant du marché français mérite d’être approfondi. Notre étude englobe toutes les opérations de CRI initiées par les entreprises du SBF 120 sur la période 2000-2018. Nos principaux résultats mettent en exergue le rôle joué par la structure de propriété, les ressources spécifiques ainsi que le profil de l’actionnariat dans la réalisation des opérations de CRI. Ainsi, ce travail contribue à l’enrichissement du débat sur l’utilité de ces véhicules de financement de l’innovation pour l’économie française.
Diversité du genre et conservatisme comptable
Authors: Sami Hind , Ureche-Rangau Loredana
Published: May 2021

Nous étudions l’impact du genre du directeur administratif et financier sur le conservatisme comptable. Utilisant un échantillon de 361 firmes françaises entre 2010-2017 nous analysons les flux opérationnels et les accruals afin de déterminer s’il existe une asymétrie dans la reconnaissance des pertes et des gains, preuve de conservatisme. Nos résultats confirment que les femmes adoptent des politiques plus prudentes dans leurs rapports financiers. Elles reconnaissent plus rapidement les pertes contribuant à la constitution d’accruals négatifs représentatifs du conservatisme. L’impact des femmes sur la qualité des rapports financiers milite en faveur de leur participation plus large aux espaces de décision.
Communication externe sur les Accords-Cadres Internationaux : entre coopération, légitimité et nouvelles tensions sociales
Authors: Negre Emmanuelle , Verdier Marie-Anne
Published: May 2021

Cette étude vise à identifier les enjeux de la communication externe relative à la signature d’Accords-Cadres Internationaux (ACIs) négociés entre multinationales et Fédérations Syndicales Internationales (FSI). Elle se base sur une étude qualitative reposant principalement sur 59 entretiens semi-directifs menés auprès d’entreprises françaises signataires d’ACIs. Les résultats montrent que la communication externe sur ces accords s’inscrit dans des logiques de coopération et de légitimité qui, de par les multiples tensions sociales qu’une telle communication suscite, se solde par une communication prudente revendiquée par les multinationales du fait des risques qu’elle peut générer.

Son éditrice et maîtresse d’oeuvre, Catherine Flohic, qui a d’abord fait ses armes dans une maison d’édition dédiée à la valorisation du patrimoine régional français, a créé en 2000 cette collection d’entretiens illustrés, qui mettent en vedette un écrivain interrogé par un proche ou un critique, dans le but de « remonte[r] le cours d’une vie à l’oeuvre ». Cette collection paraît ainsi particulièrement intéressante pour interroger la patrimonialisation de la littérature contemporaine et plus spécifiquement de l’écrivain contemporain.
L’Album NRF de François Nourissier dans les Albums de la Pléiade : patrimonialisation et célébration éditoriale1
Authors: Scibiorska Marcela
Published: May 2021

Les Albums de la Pléiade sont une série de monographies illustrées destinées à la promotion de la célèbre collection patrimoniale, la Bibliothèque de la Pléiade. Alors que la fonction publicitaire des Albums est généralement atténuée par son éditeur, Gallimard, un tome de la collection, l’Album NRF, déroge à cette règle en ce qu’il relève ouvertement de l’autopromotion éditoriale. Cet article se propose d’examiner quels moyens discursifs et médiatiques sont mis en oeuvre au sein du volume afin de véhiculer une image de la NRF en tant qu’institution au rôle crucial dans l’histoire littéraire. Finalement, nous regardons comment Gallimard procède à la patrimonialisation de son propre comptoir d’édition à la faveur du médium de la collection et de l’aura dont bénéficie la Pléiade au sein du paysage littéraire de notre temps.

Ces oeuvres nous permettent de suivre la trajectoire politique, personnelle et littéraire de l’auteur qui va du roman autobiographique, centripète, à la littérature de terrain, centrifuge ; de la quête à l’enquête ; d’une position d’autorité, de surplomb, d’une imposture en somme, à une « participation observante »,in situ, qui permet à l’intellectuel d’accepter son étrangement.
La nage en eau libre comme acte subversif : Patrolin et Deakin à contre-courant
Authors: Cornelus Hannah
Published: May 2021

Dans Waterlog. A Swimmer’s Journey Through Britain, livre qui a inspiré de nombreux lecteurs autour du monde, l’environnementaliste britannique Roger Deakin célèbre le « wild swimming » et le contact sensoriel au monde naturel. Sans connaître l’oeuvre de Deakin, l’auteur français Pierre Patrolin a publié en 2012 sa Traversée de la France à la nage, fictionnelle celle-ci. Une lecture croisée révèle que les deux livres articulent une même conception de la nage en eau libre comme activité manifestement subversive, qui s’oppose à la société de consommation numérisée et accélérée. La nage permet ainsi de rétablir le rapport corporel à la nature en activant tous les sens ; elle suscite un état de flux qui impose une certaine lenteur et immerge le nageur dans le moment présent et dans son environnement naturel. En se mouvant au ras de l’eau, le nageur voit se réduire sa perspective visuelle et renonce à la vue englobante qui est associée à la domination de la nature par l’homme. De plus, les deux textes privilégient l’environnement « banal » de leurs territoires nationaux respectifs au lieu de s’intéresser à une nature spectaculaire et sublime. La nage en eau libre est ainsi présentée comme un véritable acte de désobéissance civile, une action revendicative qui conteste la privatisation de la nature et met en pratique le « right to roam ».
Comparative transcriptome profiling of a resistant vs susceptible bread wheat (Triticum aestivum L.) cultivar in response to water deficit and cold stress

Published: May 2021

Bread wheat (Triticum aestivum L.) is one of the most important agricultural plants wearing abiotic stresses, such as water deficit and cold, that cause its productivity reduction. Since resistance to abiotic factors is a multigenic trait, therefore modern genome-wide approaches can help to involve various genetic material in breeding. One technique is full transcriptome analysis that reveals groups of stress response genes serving marker-assisted selection markers. Comparing transcriptome profiles of the same genetic material under several stresses is essential and makes the whole picture. Here, we addressed this by studying the transcriptomic response to water deficit and cold stress for two evolutionarily distant bread wheat varieties: stress-resistant cv. Saratovskaya 29 (S29) and stress-sensitive cv. Yanetzkis Probat (YP). For the first time, transcriptomes for these cultivars grown under abiotic stress conditions were obtained using Illumina based MACE technology. We identified groups of genes involved in response to cold and water deficiency stresses, including responses to each stress factor and both factors simultaneously that may be candidates for resistance genes. We discovered a core group of genes that have a similar pattern of stress-induced expression changes. The particular expression pattern was revealed not only for the studied varieties but also for the published transcriptomic data on cv. Jing 411 and cv. Fielder. Comparative transcriptome profiling of cv. S29 and cv. YP in response to water deficit and cold stress confirmed the hypothesis that stress-induced expression change is unequal within a homeologous gene group. As a rule, at least one changed significantly while the others had a relatively lower expression. Also, we found several SNPs distributed throughout the genomes of cv. S29 and cv. YP and distinguished the studied varieties from each other and the reference cv. Chinese Spring. Our results provide new data for genomics-assisted breeding of stress-tolerant wheat cultivars.
A REVIEW ON CLINICAL OUTCOMES OF BEMPEDOIC ACID AS ADD-ON THERAPY WITH EZETIMIBE FOR THE TREATMENT OF HYPERLIPIDEMIA
Authors: Vidhya D Raja , S Girija , Ganamurali Nila , Dhanasekaran Dhivya , Sabarathinam Sarvesh
Published: May 2021

Background: Cardiovascular complications are one of the leading causes of global mortality. Statins are intended to produce beneficial effects in reducing the risk of morbidity and mortality in cardiovascular patients. However, it becomes negligible in statin intolerant patients mainly due to muscle related symptoms. Objective: The objective of the study is to summarize the results of the studies available on safety and efficacy of bempedoic acid/ezetimibe combination treatment in statin intolerant patients. Methods: After comprehensive literature survey, in Cochrane Library, PubMed, Embase and Medline, randomized controlled studies involving statin intolerant hyperlipidemia, patients with low- density lipoprotein ≥200 mg/dl and at high risk of cardiovascular disease treated with Bempedoic acid and ezetimibe combination were selected. Results: For final quality analysis two clinical trials were selected to assess the safety and efficacy of the combination of Bempedoic acid and Ezetimibe. Data shows Bempedoic acid and Ezetimibe combination significantly lowered the low-density lipoprotein compared to the control groups (placebo vs Bempedoic acid vs ezetimibe). In addition, the data shows significant reduction in highly sensitive C- reactive protein, non-high density lipoprotein cholesterol, total cholesterol and apolipoprotein B. Conclusion: Overall, we conclude that the combination of Bempedoic acid and Ezetimibe can be considered as a treatment of choice for the treatment of hyperlipidemia for patients with statin-intolerance or maximally tolerated even to low-dose statins.
FORMULATION DEVELOPMENT AND CHARACTERIZATION OF NADIFLOXACIN LOADED SOLID LIPID NANOPARTICLE BASED HYDROGEL
Authors: Kumar Prashant , Khatak Sunil
Published: May 2021

The aim of this dissertation work was to develop and characterize an optimal formulation of solid lipid nanoparticles of nadifloxacin, which would then be incorporated into hydrogel. The SLN was developed with drug nadifloxacin, which is poorly water soluble. On the basis of solubility studies (i.e. partitioning effects), the lipid and components were chosen. In this study, the two variables amount of lipid and concentration of Poloxamer 188 were studied. The EE increased as the concentration of Poloxamer 188 increased. The particle size was observed to decrease as the concentration of Poloxamer 188 was increased. The EE increased in a similar way as the amount of lipid was increased. So the purpose was to formulate hydrogel with carbopol 940 with improved drug entrapment, sufficient viscosity, good extrudability, good homogeneity and improved drug release. Hydrogels are polymers that have swelling ability in water or aqueous solvent systems. Due to their increased water content, gels can provide a better feeling for skin than other conventional dosage forms. Hydrogels are insoluble in water. They are not easily removed from the application site.
Depression-related stigma among primary care providers
Authors: Kluemper Andrew , Heath Lauren , Loeb Danielle , Kroehl Miranda , Trinkley Katy
Published: May 2021

Introduction

Depression is one of the most common mental illnesses in the United States and is often treated in primary care settings. Despite its prevalence, depression remains underdiagnosed and undertreated for a variety of reasons, including stigma. This may result in suboptimal management of depression. Studies evaluating stigma in US primary care providers (PCP) are scarce. The main objective of this study was to describe stigma in a cohort of PCPs.

Methods

We utilized a validated questionnaire to measure stigma (score range 15 to 75 with lower scores indicating lower stigma levels). PCPs in 2 academic internal medicine clinics were sent an electronic questionnaire and received a small monetary incentive for responding. In addition to the stigma survey, we collected demographic data, including age, provider type, gender, and other data related to social proximity to mental illness. To describe stigma, differences in stigma between provider characteristics were evaluated using t tests and ANOVA tests as appropriate.

Results

Of 107 PCPs, 71 responded (66.4% response rate). Male responders displayed higher stigma scores than females (31.8 vs 27.4, P = .0021). Medical residents displayed higher stigma scores than nonresidents (31.3 vs 27.2, P = .0045). Providers with personal exposure to mental illness and those who reported they frequently treated depression had less stigma.

Discussion

Overall, a range of stigma was present among PCPs surveyed. Higher levels of stigma were found in men, medical residents, those without personal exposure to mental illness, younger PCPs, and those who reported treating depression less frequently. Future studies should utilize larger sample sizes and focus on the impact of stigma on quality of care.

Embedding Aligned Graphene Oxides in Polyelectrolytes to Facilitate Thermo‐Diffusion of Protons for High Ionic Thermoelectric Figure‐of‐Merit
Authors: Jeong Myunghwan , Noh Juran , Islam Md Zahidul , Kim Kyomin , Sohn Ahrum , Kim Woochul , Yu Choongho
Published: May 2021

Recently emerged ionic thermoelectric conversion with the Soret effect is advantageous in providing large thermopower on the order of ≈1–10 mV K−1, but the origin of the large thermopower and the methodology of attaining superior thermoelectric performances are yet to be disclosed. Here, key parameters and their optimization for outstanding thermoelectric responses with polystyrene sulfonic acid (PSS‐H) are unveiled. It is found that the thermo‐diffusion of water boosts proton transport, playing a key role in obtaining large ionic thermopower by promoting unidirectional migration of protons from a hotter to colder side. When graphene oxide (GO) embedded in PSS‐H is aligned along the transport direction of protons and water, their diffusion along the in‐plane direction of GO is promoted, enlarging both ionic thermopower and ionic electrical conductivity. PSS‐H containing 3 wt% GO possesses extremely large ionic power factors up to 1.8 mW m−1 K−2 and ionic figure‐of‐merits up to 0.85 at 23 °C. This study provides not only preeminent thermoelectric performances based on ion transport but also identifies the influence of the key parameters on thermoelectric properties, suggesting controllability of thermo‐diffusion of ions depending on inclusions in base materials, which will draw numerous subsequent research with their alterations.
Injectability of Biosynthetic Hydrogels: Consideration for Minimally Invasive Surgical Procedures and 3D Bioprinting
Authors: Birman Tamara , Seliktar Dror
Published: May 2021

Injectable hydrogels are often preferred when designing carriers for cell therapy or developing new bio‐ink formulations. Biosynthetic hydrogels, which are a class of materials made with a hybrid design strategy, can be advantageous for endowing injectability while maintaining biological activity of the material. The chemical modification required to make these gels injectable by specific crosslinking pathways can be challenging and also make the hydrogels inhospitable to cells. Therefore, most efforts to functionalize biosynthetic hydrogel precursors toward injectability in the presence of cells try to balance between chemical and biological functionality, in order to preserve cell compatibility while addressing the injectability design challenges. Accordingly, hydrogel crosslinking strategies have evolved to include the use of photoinitiated “click” chemistry or bio‐orthogonal reactions with rapid gelation kinetics and minimal cyto‐toxicity required when working with cell‐compatible hydrogel systems. With many new injectable biosynthetic materials emerging, their impact in cell‐based regenerative medicine and bioprinting is also becoming more apparent. This review covers the main strategies that are used to endow biosynthetic polymers with injectability through rapid, cyto‐compatible physical or covalent crosslinking and the main considerations for using the resulting injectable hydrogels in cell therapy, tissue regeneration, and bioprinting.
Low temperature tolerance at early growth stage of maize hybrids released in the 1970s–2000s

Published: May 2021

Early freezes in the spring are becoming increasingly common. To protect farmers from low temperatures (LT), crops need improved LT tolerance. The hypothesis of this paper is that maize (Zea mays L.) hybrids released in the 2000s had higher LT tolerances than those released in the 1970s. In the study, eight popular maize released between 1970 and 2010 were subjected to LT in four different trials. Germination time, growth uniformity, recovery ability from LT stress, and leaf productivity at seedling stage are important indicators in evaluating LT tolerance of maize. Hybrids released in the 1970s had a higher gibberellin A3 (GA3) content in seeds, which resulted in faster germination in LT (P = .02). In contrast, plant growth uniformity of the 2000s hybrids were higher than that of the 1970s hybrids in LT (P = .00 at emergence). Upon being returned to warm temperatures, the 2000s hybrids recovered more rapidly than old ones mainly because of the larger root systems, higher GA3, and indole‐3‐acetic acid (IAA) content in seedlings. In addition, the 2000s hybrids had a higher chlorophyll content, Fv/Fm, soluble sugar and starch content, and antioxidant enzyme activity in seedlings than old hybrids in LT, which can also contribute to a fast recovery from LT stress. Based on the growth uniformity and recovery ability from LT stress, new hybrids showed a higher LT tolerance than old hybrids during early growth stage. This study showed the genetic tolerance in LT may exist in hybrids that were released 50 yr ago, and that exporting differences between hybrids possible mechanism of temperature tolerance can be identified.

Separation of acetylene from carbon dioxide remains a daunting challenge because of their very similar molecular sizes and physical properties. We herein report the first example of using copper(I)‐alkynyl chemistry within an ultra‐microporous MOF (CuI@UiO‐66‐(COOH)2) to achieve ultrahigh C2H2/CO2separation selectivity. The anchored CuIions on the pore surfaces can specifically and strongly interact with C2H2molecule through copper(I)‐alkynyl π‐complexation and thus rapidly adsorb large amount of C2H2at low‐pressure region, while effectively reduce CO2uptake due to the small pore sizes. This material thus exhibits the record high C2H2/CO2selectivity of 185 at ambient conditions, significantly higher than the previous benchmark ZJU‐74a (36.5) and ATC‐Cu (53.6). Theoretical calculations reveal that the unique π‐complexation between CuIand C2H2mainly contributes to the ultra‐strong C2H2binding affinity and record selectivity. The exceptional separation performance was evidenced by breakthrough experiments for C2H2/CO2gas mixtures. This work suggests a new perspective to functionalizing MOFs with copper(I)‐alkynyl chemistry for highly selective separation of C2H2over CO2.

The functionalization of C−H bonds in light alkanes, particularly to form C−N bonds, remains a challenge. We report the dehydrogenative coupling of amides with C1–C4 hydrocarbons to form N‐alkyl amide products with tBuOOtBu as oxidant, and a copper complex of a phenanthroline‐type ligand as catalyst. The reactions occurred in good yields in benzene or supercritical carbon dioxide as solvents. This strategy allowed for the determination of the relative reactivity of these alkane C−H bonds toward this amination process and showed, in contrast to prior work with larger alkanes, that the reactivity correlated with bond dissociation energies.

Based on liquid crystal elastomer (LCE) materials, hierarchically structured soft actuators can meet some requirements for “human‐friendly” working mode and execute complex tasks with intelligent adaptation to environmental changes. However, few researchers have paid much attention to the preparation methods of multicomponent/hierarchical LCE actuators. In this communication, we demonstrate the successful integration of an exchangeable diselenide chain extender for the preparation of dynamic LCEs, which could be reprogrammed on heating or under visible light illumination. Moreover, the rearrangeable polydiselenide networks could be applied to develop the self‐welding technology toward fabricating hierarchically structured LCE actuators with sophisticated deformability without using any auxiliary reagent (adhesive, tape, catalysts or initiator) during the assembling process.

Wir berichten über eine 12‐stufige Totalsynthese des Naturstoffes Dysiherbol A, eines stark entzündungshemmenden und antitumoralen Avaran‐Meroterpens aus dem Meeresschwamm Dysidea sp. Als Schlüsselschritte dienen eine enantioselektive Cu‐katalysierte 1,4‐Addition mit Abfangen des Enolates, eine Gold‐katalysierte Doppelcyclisierung zum Aufbau des tetracyclischen Kohlenstoff‐Gerüsts sowie die späte Einführung der C5‐Brückenkopf‐Methylgruppe durch Protonen‐induzierte Cyclopropan‐Öffnung unter spontaner Ausbildung einer Etherbrücke. Die erhaltene pentacyclische Verbindung (entsprechend einem Anhydrid der ursprünglich für Dysiherbol A vorgeschlagenen Struktur) zeigte identische spektroskopische Daten wie der Naturstoff, jedoch einen entgegengesetzten Drehwert. CD‐spektroskopische Messungen bestätigten, dass sowohl die Konstitution als auch die absolute Konfiguration der ursprünglich für (+)‐Dysiherbol A vorgeschlagenen Struktur revidiert werden müssen.
Reply to Comment on “Highly Selective Removal of Perfluorinated Contaminants by Adsorption on All‐Silica Zeolite Beta”
Authors: Vercammen Jannick , De Vos Dirk
Published: May 2021

All‐silica Beta zeolite was recently proven by our group to display a surprisingly high capacity and affinity for perfluorooctanoic acid and perfluorooctanesulfonic acid even in the presence of an excess of competing low‐molecular organic compounds. We reply to a comment, which argues that this zeolite's performance does not surpass that of some specific carbon materials.
Distributed dynamic event‐triggered control approach to multi‐agent systems via adaptive consensus protocols
Authors: Zhao Guanglei , Wei Haoxiong , Fu Xiuwei
Published: May 2021

This paper studies the event‐triggered consensus problem of multi‐agent system with general linear dynamics. A novel dynamic event‐triggering mechanism (ETM) is proposed, and it is formally shown that the proposed dynamic ETM can achieve larger triggering intervals than the existing ones. Then, a distributed adaptive control protocol is developed with the updating law of coupling strength. With the proposed adaptive control protocol and dynamic ETM, the event‐triggered consensus control protocol can be implemented in a fully distributed way. Moreover, Zeno behavior can be ensured to be excluded, and an algorithm is developed such that the implementation of the proposed consensus control protocol does not need continuous communication between neighboring agents. Finally, the effectiveness of the proposed methods is illustrated by a numerical example.
Stabilizing a spherical pendulum on a quadrotor

Published: May 2021

In this article, we design a backstepping control law based on geometric principles to swing up a spherical pendulum mounted on a moving quadrotor. The available degrees of freedom in the control vector also permit us to position the plane of the quadrotor parallel to the ground. The problem addressed here is, indeed, novel and has many practical applications which arise during the transport of a payload mounted on top of a quadrotor. The modeling and control law are coordinate‐free and thus avoid singularity issues. The geometric treatment of the problem greatly simplifies both the modeling and control law for the system. The control action is verified and supported by numerical experiments for aggressive maneuvers starting very close to the downward stable equilibrium position of the pendulum.
Wilhelm Rudolf Kutter – Portrait eines Wasserbauingenieurs
Authors: Vockrodt Hans‐Jörg
Published: May 2021

Beim Studium historischer Erläuterungsberichte, wie bspw. zum Bau des Erfurter Flutgrabens in den Jahren 1890–1898, stößt man immer wieder auf die sog. „Kuttersche Formel“ und damit auf die Frage, wer eigentlich der Namensgeber dieser hydraulischen Abflussformel war. In den allgemeinen, frei zugänglichen Quellen findet man hierzu nur begrenzte Hinweise, welche im Wesentlichen den wissenschaftlich‐technischen Hintergrund erläutern. Unterzieht man sich aber der Mühe, die familiären Beziehungen über vier Generationen hinweg zu recherchieren, und hat man dabei noch das Glück, mit Samuel Kutter einen promovierten Physiker als Ururenkel zu finden, so kann man auch heute noch ein beeindruckendes Portrait von Wilhelm Rudolf Kutter nachzeichnen.

Castor protein isolate (CPI) was prepared by aqueous solubilization of defatted castor kernel meal under alkaline conditions (pH 12.0), with precipitation at the isoelectric point (pH 5.0) followed by heat treatment. Five experimental diets were prepared by substituting soybean protein isolate (SPI) at 0%, 25%, 50%, 75%, and 100% with CPI based on protein equivalent basis. The diets were assigned as control, PI25, PI50, PI75, and PI100, respectively. A 60‐day feeding trial was conducted following a completely randomized design. Results revealed significant improvement in growth rates, feed conversion, and protein retention in Labeo rohita fingerlings (P < 0.05) at 124.50 g CPI kg−1 diet (PI75). However, these were similar between control and PI100 (P > 0.05). Dietary CPI did not alter the hepatosomatic index, viscerosomatic index, survival, carcass composition (except crude protein), and digestive enzymes (P > 0.05). The metabolic enzymatic profile of rohu fingerlings was significantly affected due to dietary treatments (P < 0.05) but oxidative stress enzymes were not affected by feeding of CPI. The activity of the aminotransferases, lactate dehydrogenase, and malate dehydrogenase did not differ (P > 0.05) between control and PI100. The preparation of protein isolate is therefore a way forward for the effective valorization of toxic castor meal and could be used at 164.0 g kg−1 inclusion (complete substitution of soybean protein isolate) in the diet of L. rohita. © 2021 Society of Industrial Chemistry and John Wiley & Sons Ltd.
Characteristics of quantifiers moderate the framing effect
Authors: Holford Dawn L. , Juanchich Marie , Sirota Miroslav
Published: May 2021

The attribute framing effect, where people judge a quantity of an item more positively with a positively described attribute (e.g., “75% lean”) than its negative, albeit normatively equivalent description (e.g., “25% fat”), is a robust phenomenon, which may be moderated under certain conditions. In this paper, we investigated the moderating effect of the characteristics of the quantifier term: its format (verbal, e.g., “high,” or numerical, e.g., “75%”) and magnitude (i.e., if it is a small or large quantity) using positive or negative synonyms of attributes (e.g., energy vs. calories). Over five pre‐registered studies using a 2 (synonym, between‐subjects: positive or negative) × 2 (quantifier format, between‐subjects: verbal or numerical) × 2 (quantifier magnitude, within‐subjects: small or large) mixed design, we manipulated quantifier format and magnitude orthogonally for synonyms with differing valence. We also tested two mechanisms for the framing effect: whether the effect was mediated by the affect associated with the frame and whether participants inferred the speaker to be positive about the target. We found a framing effect with synonyms that was reversed in direction for the small (vs. large) quantifiers, but not significantly moderated by quantifier format. Both the affect associated with the frame and the inferred level of speaker positivity partially mediated the framing effect, and the level of mediation varied with quantifier magnitude. These results suggest that the magnitude of the quantifier modifies one's evaluation of the frame, and the mechanism for people's evaluations in a framing situation may differ for small and large quantifiers.
