Revisiting the OH + H2 → H2O + H reaction at the molecular level: the plausible catalytic role of ice in its own reconstruction
Authors: Redondo P. , Pauzat F. , Markovits A. , Ellinger Y. 
Published: December 2020

Context. In spite of the permanent damage suffered from the radiation field (cosmic rays, X-rays, and intense UV-visible radiations), interstellar grains are still covered by ices mantles whose role in interstellar chemistry is well beyond any doubt. This clearly means that the destruction of the ice cover has to be counterbalanced by efficient reconstruction mechanisms.
Aims. Our goal is to determine whether the ice, which is still present after irradiation, has a catalytic role in the OH + H2 → H2O + H reaction for its own reconstruction. We focus on the three plausible reaction paths depending on the way reactants OH or H2 are adsorbed at the ice surface.
Methods. Calculations were performed in both cluster and solid state approaches, using ab-initio post Hartree-Fock methods for small systems, standard density functional theory (DFT) for larger clusters, and periodic solid state DFT with specific formalisms accounting for weak interactions in systems of infinite dimensions.
Results. Although the end product is the same, that is namely the reconstruction of one H2O on the subjacent ice, three different reaction paths are found depending on whether H2 reacts with adsorbed OH(ads), wether OH reacts with adsorbed H2(ads) or wether both OH(ads) and H2(ads) are adsorbed on the ice before reacting. In the first case, there is an activation barrier of ~6 kcal mol−1, requiring the tunneling effect for the reaction to proceed, which is in agreement with preceding studies. In the second case, the reaction is a barrierless process leading to the direct reconstruction of the ice. In the third case, the double adsorption increases the activation barrier due to the lowering of the starting energy. This is found regardless of the dimension of the supporting ice aggregates.
Conclusions. Icy grain surfaces play a critical role for their own reconstruction in cold, dense interstellar clouds. The prevalence of tunneling over the direct mechanism should strongly depend on the temperature and local environment.
The pulsational properties of ultra-massive DB white dwarfs with carbon-oxygen cores coming from single-star evolution
Authors: Córsico Alejandro H. , Althaus Leandro G. , Gil Pons Pilar , Torres Santiago 
Published: December 2020

Context. Ultra-massive white dwarfs are relevant for many reasons: their role as type Ia supernova progenitors, the occurrence of physical processes in the asymptotic giant branch phase, the existence of high-field magnetic white dwarfs, and the occurrence of double white dwarf mergers. Some hydrogen-rich ultra-massive white dwarfs are pulsating stars and, as such, they offer the possibility of studying their interiors through asteroseismology. On the other hand, pulsating helium-rich ultra-massive white dwarfs could be even more attractive objects for asteroseismology if they were found, as they should be hotter and less crystallized than pulsating hydrogen-rich white dwarfs, something that would pave the way for probing their deep interiors.
Aims. We explore the pulsational properties of ultra-massive helium-rich white dwarfs with carbon-oxygen and oxygen-neon cores resulting from single stellar evolution. Our goal is to provide a theoretical basis that could eventually help to discern the core composition of ultra-massive white dwarfs and the scenario of their formation through asteroseismology, anticipating the possible future detection of pulsations in helium-rich ultra-massive white dwarfs.
Methods. We focus on three scenarios for the formation of helium-rich ultra-massive white dwarfs. First, we consider stellar models coming from two recently proposed single-star evolution scenarios for the formation of ultra-massive white dwarfs with carbon-oxygen cores that involve the rotation of the degenerate core after core helium burning and reduced mass-loss rates in massive asymptotic giant branch stars. Finally, we contemplate ultra-massive oxygen-neon core white-dwarf models resulting from standard single-star evolution. We compute the adiabatic pulsation gravity-mode periods for models in a range of effective temperatures, embracing the instability strip of average-mass pulsating helium-rich white dwarfs, and we compare the characteristics of the mode-trapping properties for models of different formation scenarios through the analysis of the period spacing.
Results. Given that the white dwarf models coming from the three scenarios considered are characterized by distinct core chemical profiles, we find that their pulsation properties are also different, thus leading to distinctive signatures in the period-spacing and mode-trapping properties.
Conclusions. Our results indicate that in the case of an eventual detection of pulsating ultra-massive helium-rich white dwarfs, it would be possible to derive valuable information encrypted in the core of these stars in connection with the origin of such exotic objects. This is of the utmost importance regarding recent evidence for the existence of a population of ultra-massive white dwarfs with carbon-oxygen cores. There will soon be many opportunities to detect pulsations in these stars through observations collected with ongoing space missions.
Recent Therapeutic Interventions of Fenugreek Seed: A Mechanistic Approach
Authors: Idris Sahar , Mishra Anuradha , Khushtar Md 
Published: December 2020

AbstractFenugreek seeds have widespread relations with Ayurveda, Unani, and Arabic medicine. The seeds were useful for the treatment and prevention of different ailments. Fenugreek (Trigonella foenum-graecum) or methi is from the Leguminosae family and are primarily known for its anti-diabetic and hypocholesterolemic activities. The germinated fenugreek seeds were used in the treatment of E.coli infection in Germany and France. The important phytoconstituents responsible for such medicinal applications are saponins, polyunsaturated fatty acids, galactomannans, trigonelline, and 4-hydroxy isoleucine. Flavonoids, apigenin 6,8-di-C-glucoside, apigenin-6-C-glucosyl-8-C-galactoside, 6-Cgalactosyl- 8-C-arabinoside are the chief ingredients of fenugreek seeds; responsible for reducing blood glucose while given to diabetic rats, whereas important flavones are epigenin, luteolin and vitexin. The other major bioactive components in fenugreek seeds are polyphenols like rhaponticin and isovitexin. Fenugreek seeds contain phosphorus and are categorized into different classes such as inorganic phosphorus, phospholipids, phytates, phosphor-proteins, and nucleic acid. Germinated seeds profusely filled with amino acids with amino acids, proteins, ascorbic acid, sugars. Further, this review shares information about the recent therapeutic intervention not covered earlier; on in vivo and in vitro and some clinical applications against certain interesting ailments other than older applications. This review includes certain nano delivery systems of Fenugreek seeds and their medicinal application.

Authors: Friebe Michael P. , LeGrand Joseph R. , Shepherd Bryan E. , Breeden Elizabeth A. , Nelson Scott D. 
Published: December 2020

Abstract
Background The American Geriatrics Society recommends against the use of certain potentially inappropriate medications (PIMs) in older adults. Prescribing of these medications correlates with higher rates of hospital readmissions, morbidity, and mortality. Vanderbilt University Medical Center previously deployed clinical decision support (CDS) to decrease PIM prescribing rates, but recently transitioned to a new electronic health record (EHR).
Objective The goal of this study was to evaluate PIM prescribing rates for older adults before and after migration to the new EHR system.
Methods We reviewed prescribing rates of PIMs in adults 65 years and older, normalized per 100 total prescriptions from the legacy and new EHR systems between July 1, 2014 and December 31, 2019. The PIM prescribing rates before and after EHR migration during November 2017 were compared using a U-chart and Poisson regression model. Secondary analysis descriptively evaluated the frequency of prescriber acceptance rates in the new EHR.
Results Prescribing rates of PIMs decreased 5.2% (13.5 per 100 prescriptions to 12.8 per 100 prescriptions; p < 0.0001) corresponding to the implementation of alternatives CDS in the legacy EHR. After migration of the alternative CDS from the legacy to the new EHR system, PIM prescribing rates dropped an additional 18.8% (10.4 per 100 prescriptions; p < 0.0001). Acceptance rates of the alternative recommendations for PIMs was low overall at 11.1%.
Conclusion The prescribing rate of PIMs in adults aged 65 years and older was successfully decreased with the implementation of prescribing CDS. This decrease was not only maintained but strengthened by the transition to a new EHR system.

Authors: Bezdek Máté J. , Luo Shao-Xiong Lennon , Ku Kang Hee , Swager Timothy M. 
Published: December 2020

Significance
Methane is potentially explosive and is a major threat to environmental health as a potent greenhouse gas. However, its volatility and nonpolar nature render selective methane detection a significant challenge. Here we report a chemiresistive sensor based on single-walled carbon nanotubes and a molecular platinum-polyoxometalate complex known to mediate methane oxidation near ambient conditions. We show that the composite is a robust sensor that operates at room temperature, exhibits air and moisture stability, as well as selectivity for methane. Our results demonstrate that concepts in molecular methane oxidation can be leveraged to develop low-power, low-cost, and potentially distributable sensors for selective methane detection.
A sociological study of Howard Goldblatt’s English translations of the ideological markers in Mo Yan’s three Chinese novels
Authors: Wu Guangjun 
Published: December 2020

AbstractOver the last two decades, ideology has evolved into a major issue in translation studies. In terms of the ideological explorations of translation, previous studies focused on the explicit or implicit ideological manifestations in translated texts, or how translation was used to serve ideology. Studies on the diachronic changes of translator’s ideology, however, remain scarce. This study of Howard Goldblatt’s English translations of three Chinese novels over three different periods finds that translators’ ideology is dynamic rather than static. In their translations, translators may follow the ideology of the source culture or that of the target culture, depending on the relative status of the source culture and the target culture as well as the capital possessed by the author and the translator. A sociological account is provided to explain the changes in translators’ ideology over time.

Published: December 2020

Abstract
One type of the considerable potential of Indonesia is its natural resources, specifically plants, andJamaican cherry is one example, a type of tall-growing flora easy to live and grow profusely in the country. However, only a few people get its best benefit, for example, from its leaves containing flavonoid and tannin useful in textile dyeing. This research contributes to ecofashion development, presented to determine the effect of fixation substances on ecoprint dyeing using Jamaican cherry leaves (Muntingia calabura L.) with steaming technique in terms of the hue directions investigated through three different color test results. The study was conducted with an ecoprint dyeing experiment whose results were then tested by using hue difference tests in the laboratory. Thedyeing experiment employedmedium-aged cherry leavessteamed together with the selected textiles. The fixation substances used to display and lock colors were iron (ferrous sulfate), alum, and calcium carbonate. The steaming process was carried out twice,30 minutes for each, and the fixation process was done by submersing the fabric for 5-10 minutes. The results show that fixation substances affectthe fabric’s hue directions. With alum, the results of the dyeingare leafy and brownish-yellow, while with alum, black green dominates, and with thecalcium carbonate the color is brownish-green. The results are applicable in environmentally friendly textile manufacturing and inspire further research with other types of plants.

Published: December 2020

Abstract
This study aimed to: describe the value of color fastness to washing by using five types of detergent namely cream, powder, bar, liquid, and Sapindusrarak on Tan written batik cloth with naphthol dyes; determine the effect of the detergent types on the color fastness; and find out the best type of detergent according to its composition for washing batik with naphthol dyes. This was true experimental research with the AXB factorial design in which A is the Tan batik cloth, and B is the factor of washing treatment with five detergent types. To collect the data, the researchers employed the probability sampling technique, which is asimple random sampling technique. Also, they tested the color fastness in the washing processes carried out by the examining team at the Batik and Craft Center with procedures and calibrated tools.The data were analyzed using a non-parametric analysis, namely, a Kruskal-Wallis test. The color fastness test of Tan batik cloth washed using five types of detergent produces a good average value of 4- 4.5. The result of the difference test on thecolor fastness to washing and staining is p 0.406> 0.05. It means there is no significant difference becausethe detergents have the same composition, i.e., an anionic surfactant.The detergent with the best composition is Sapindusrarak, because it contains saponin as a natural surfactant. People can use detergents to wash batik by selectingthe composition of lauryl alkyl benzene sulfonate as a soft substance.

Published: December 2020

Abstract
UPI has successfully developed a smokeless incinerator. Incinerator combustion occurs at high temperatures. High temperature is the potential energy that can be converted into electricity. The innovation space is still open here to increase the ability of the UPI incinerator to become part of a system that can generate electricity by utilizing the burning of waste that occurs in the incinerator. This conversion system uses the Rankine Cycle. The Rankine cycle utilizes water as its working fluid. This research is targeted to get the design of an incinerator heat energy conversion system into electricity by using classical basic Rankine cycle. The investigation will vary three different pumps to get the best performance. The performance parameter are the cycle thermal efficiency and net power produced by the cycle. The design process starts with the calculation of potential heat from waste combustion. The calculation uses the LHV value of municipal solid waste and the second heat source comes from reaction of LPG which consists of 48.5% propane, 48.5% butane and 3% pentane and air which consists of 79% Nitrogen and 21% Oxygen. The reaction is assumed perfect and Nitrogen is not reacted. Total heat is 581.4 kW which comes from 574 kW from LHV of municipal waste and 7.76 kW from the reaction of LPG and air. The heat transferred to work fluid comes from 50% LHV of municipal waste and 14% from the reaction of LPG and air. The cycle can produce 55.5 kW power and the efficiency is 13%. The cycle use 600W water pump with 8 liter/min debit. Debit is the important parameter to get better power output and efficiency from heat of incinerator waste combustion.
