Ionic Liquids for Desulphurization: A Review

The literature survey has shown that not much work has been reported on the interaction mechanism of ionic liquids (ILs) with sulfur in model oil system. In recently published work, the interaction was predicted using COSMO-RS where the strength of hydrogen bond of anion should be reduced in order to increase thiophene extraction capacity. On the other hand, the same researchers also found that the smaller sized cations would lead to higher selectivity, which could lower the capacity and vice versa. While others have reported that the absorption capacity of sulfur compounds in ILs are strongly dependent on the chemical structures, physical properties and compactness between the cation and the anion of the ILs. However, these conclusions lead to a broad selection of ILs for extractive desulphurization process.
Prognostic Factor Utility of BAP1 Immunohistochemistry in Uveal Melanoma: A Single Center Study in Spain

Simple Summary As uveal melanoma metastasis rates are still very high, the mechanisms by which it spreads need to be evaluated. Our research sought to determine which pathological and clinical features were correlated with the prognosis of uveal melanoma in a Spanish community. BAP1 (BRCA1-Associated Protein 1) gene mutation is one of the strongest predictors for metastasis in uveal melanoma. The BAP1 protein has a tumor suppressor function and the presence of the BAP1 protein can be shown using immunohistochemical staining. Our study showed that nuclear BAP1 immunostaining had a significant correlation with survival rate in our sample, and patients with a lack of nuclear BAP1 immunostaining should be considered high-risk and receive a close follow-up. This stain can be used as routine technique in the pathological examination of uveal melanoma. Abstract Even today, the mortality rate for uveal melanoma (UM) remains very high. In our research, we sought to determine which pathological and clinical features were correlated with the prognosis of UM. BAP1 (BRCA1-Associated Protein 1) gene mutation has been analyzed as one of the strongest predictors for metastasis in UM. The BAP1 gene codifies the BAP1 protein which has a tumor suppressor function. The presence of this protein can be determined by BAP1 immunohistochemical staining. Eighty-four uveal melanoma patients and forty enucleated eyeballs were examined. Metastasis was present in 24 patients. Nuclear BAP1 staining was low in 23 patients. The presence of a higher large basal diameter tumor (p < 0.001), tumor infiltrating lymphocytes (p = 0.020), and a lack of nuclear BAP1 immunostaining (p = 0.001) ocurred significantly more often in the metastatic group. Metastasis-free survival was lower in patients with low nuclear BAP1 staining (p = 0.003). In conclusion, to the best of our knowledge, this is the first time that BAP1 staining has been studied in uveal melanoma in a Spanish community. We believe that this technique should become routine in the pathological examination of uveal melanoma in order to allow adequate classification of patients and to establish an individual follow-up plan.
Transdiagnostic Approaches to Sexual- and Gender-Minority Mental Health

Sexual- and gender-minority individuals experience minority stress, which is hypothesized to underlie the mental-health disparities affecting these populations. Drawing on advances in the classification of mental disorders, we argue that transdiagnostic approaches hold great promise for understanding and reducing these disparities. In contrast to traditional diagnostic approaches, which have limited construct validity and have produced a piecemeal literature, transdiagnostic approaches (a) are evidence based, (b) account for diffuse patterns of disparities and comorbidity, (c) pinpoint psychological mechanisms linking minority stress to poor mental health, (d) reduce scientific stigma, and (e) identify efficacious and efficient points of intervention for treatment of negative outcomes of minority stress.
Complexation of transition metals by chelators added during mashing and impact on beer stability

Beer inevitably changes due to an array of staling reactions. A major factor in beer ageing is the involvement of transition metals (iron, copper, manganese) in oxidative reactions. To tackle the flavour stability issue, metal chelation was investigated. Based on previous research, five primary chelators (tannic acid, gallic acid, EDTA, citric acid and phytic acid) were screened using experimental design for their capacity to reduce the content of wort transition metals. The chelating agents were added under varying conditions (mash out temperature, mash pH, grain bill, chelator concentration, addition time) during laboratory scale mashing to assess how they altered complexation and metal load. Fourteen alternative chelators (ferulic acid, tartaric acid, quercetin, chlorogenic acid and ten polyphenolic foodextracts: green tea, pomegranate, grape seed, reishi, cinnamon, curcuma, milk thistle, ginkgo, grapefruit seed and raspberry) were also explored. Metal ions were analysed using inductively coupled plasma optical emission spectrometry and wort oxidative stability by electron spin resonance spectroscopy. Mash pH was the most decisive of all tested process variables: acidified mashing (pH 6 to 5) produced worts with more iron, manganese and zinc (230, 320 and 150%, respectively). Addition of effective chelators counteracted this undesirable effect for iron. Green tea extract, tannic acid and, particularly, pomegranate extract all resulted in lower wort iron. Conversely, addition of EDTA, caused iron, manganese and zinc to increase. Pomegranate extract (90% ellagic acid) was the best performing chelator and reduced radical generation in wort (80% reduction by 60 mg/L addition), making it a promising novel compound in the improvement of beer shelf life. © 2021 The Authors.

Linking uncertainty in simulated Arctic ozone loss to uncertainties in modelled tropical stratospheric water vapour

Abstract. Stratospheric water vapour influences the chemical ozone loss in the polar stratosphere via control of the polar stratospheric cloud formation. The amount of water vapour entering the stratosphere through the tropical tropopause differs substantially between simulations from chemistry–climate models (CCMs). This is because the present-day models, e.g. CCMs, have difficulties in capturing the whole complexity of processes that control the water transport across the tropopause. As a result there are large differences in the stratospheric water vapour between the models. In this study we investigate the sensitivity of simulated Arctic ozone loss to the simulated amount of water vapour that enters the stratosphere through the tropical tropopause. We used a chemical transport model, FinROSE-CTM, forced by ERA-Interim meteorology. The water vapour concentration in the tropical tropopause was varied between 0.5 and 1.6 times the concentration in ERA-Interim, which is similar to the range seen in chemistry–climate models. The water vapour changes in the tropical tropopause led to about 1.5 ppmv less and 2 ppmv more water vapour in the Arctic polar vortex compared to the ERA-Interim, respectively. The change induced in the water vapour concentration in the tropical tropopause region was seen as a nearly one-to-one change in the Arctic polar vortex. We found that the impact of water vapour changes on ozone loss in the Arctic polar vortex depends on the meteorological conditions. The strongest effect was in intermediately cold stratospheric winters, such as the winter of 2013/2014, when added water vapour resulted in 2 %–7 % more ozone loss due to the additional formation of polar stratospheric clouds (PSCs) and associated chlorine activation on their surface, leading to ozone loss. The effect was less pronounced in cold winters such as the 2010/2011 winter because cold conditions persisted long enough for a nearly complete chlorine activation, even in simulations with prescribed stratospheric water vapour amount corresponding to the observed values. In this case addition of water vapour to the stratosphere led to increased areas of ICE PSCs but it did not increase the chlorine activation and ozone destruction significantly. In the warm winter of 2012/2013 the impact of water vapour concentration on ozone loss was small because the ozone loss was mainly NOx-induced. The results show that the simulated water vapour concentration in the tropical tropopause has a significant impact on the Arctic ozone loss and therefore needs to be well simulated in order to improve future projections of the recovery of the ozone layer.
Characteristics of the Effective Scale Height in the Topside Ionosphere Extracted From Swarm A and Digisonde Observations: Preliminary Results

The ionospheric scale height is a key parameter that defines the shape of the electron density profile. Given that its direct calculation requires knowledge of the physical and chemical state of the plasma, the concept of the effective scale height was proposed to facilitate its application. It is defined as the scale height that fits the electron density profiles with the α‐Chapman function. Its main characteristics, including the diurnal and altitudinal variation are still under investigation. This paper focuses on the specification of its key characteristics at middle latitudes based on coincident Digisonde and Swarm A satellite data. Based on the assumption that the topside electron density profile is approximated with the α‐Chapman model of variable scale height, the effective scale height at the Swarm A altitude is calculated and compared with the effective scale height at hmF2 $hmF2$ . A general conclusion is that the topside effective scale height at ∼450 km exhibits a diurnal variation with highest values in the early morning and evening sectors, while at hmF2 $hmF2$ it gets its maximum values at noon. At night, the effective scale height tends to increase with altitude, however in the daytime, its behavior is more complex. On a local scale, evidence for connection between spread F irregularities and high variability in the topside effective scale height is reported. These preliminary results indicate the potential to further exploit Swarm and Digisonde data for the development of a model for the effective scale height, able to support realistic electron density reconstruction models.
Comparison of the Scorpionism Caused by Centruroides margaritatus, Tityus pachyurus and Tityus n. sp. aff. metuendus Scorpion Venoms in Colombia

Among other scorpion species, Colombia has two genera of the Buthidae family Centruroides and Tityus, considered to be dangerous to humans. This research shares scientific knowledge aiming to a better understanding about the pathophysiological effects of such venoms. The venom of the three species: Centruroides margaritarus, Tityus pachyurus, and T. n. sp. aff. metuendus with biomedical interest were studied. An initial pre-glycemic sample was taken from ICR mice. They were later intraperitoneally inoculated with doses of 35% and 70% of LD50 of total venom. Poisoning signs were observed during a 6-h period to determine the level of scorpionism. After observation, a second glycemic sample was taken, and a histopathological evaluation of different organs was performed. This work revealed that all three venoms showed considerably notorious histopathological alterations in main organs such as heart and lungs; and inducing multiple organ failure, in relation to the glycemia values, only C. margaritatus and T. n. sp. aff. metuendus showed significant changes through manifestation of hyperglycemia. According to the Colombian scorpionism level; signs were mild to severe affecting the autonomous nervous system.
What Is Women’s Work? Reflections from Four North Indian Urban Clusters

The actual extent of the female employment challenge in India is much debated. Data on female labour force participation (FLFP) in India is hampered by shortcomings in data validity and data accuracy. The objective of this article is to explore challenges to data accuracy through two potential sources of error: measurement error and reporting error. Drawing on a unique source of granular survey data from households in four north Indian urban clusters, we demonstrate that the precise nature of the survey employed has meaningful impacts on the reporting of FLFP. Furthermore, the gender composition of respondents also seems to matter although, after controlling for gender, self-reporting is indistinguishable from proxy reporting.
Diversity of Flowering Insects and Their Impact on Yields of Phaseolus Vulgaris L. (Fabaceae) in Yaoundé (Cameroon)

To evaluate the diversity and impact of insect pollinators on pod and seed yields of Phaseolus vulgaris (red bean with small seeds), its foraging and pollinating behavior were studied in Yaoundé, during the mild raining season (March-June) in 2016 and 2017. Treatments included unlimited floral access by all visitors and bagged flowers to avoid all insect pollinators. For each year of study, observations were made on 55 ± 38 flowers per treatment. The seasonal rhythm of insects activities, its foraging behavior, and its impact on pollination (fruiting rate, number of seeds/pod and percentage of normal seeds) were recorded. Fourteen insect species visited P. vulgaris flowers. Out of 667 visits, Xylocopa olivacea, Halictus sp. , Chalicodoma sp. and Apis mellifera adansonii were the most frequent visitors with 21.43 %, 19.49 %, 12.44 % and 10.04 % visits respectively. These insects collected nectar and pollen intensely and regulatedly. The foraging activities of insect pollinators increased the fruiting rate by 23.56 %, the number of seeds/pod by 46.31 % and the normal seeds by 21.49 %. Therefore, conservation of nests and colonies of insect pollinators close to P. vulgaris crop fields should be recommended to improve pod and seed production in the region.
Potential solution-induced HfAlO dielectrics and their applications in low-voltage-operating transistors and high-gain inverters

Recently, much attention has been paid to the investigation of solution-driven oxides for application in thin film transistors (TFTs). In current study, a fully solution-based method, using 2-methoxyethanol as solvent, has been adopted to prepare InZnO thin films and HfAlOx gate dielectrics. Amorphous HfAlOx thin films annealed at 600 °C have shown a high transparency (>85%), low leakage current density (6.9 × 10−9 A cm−2 at 2 MV cm−1), and smooth surface. To verify the potential applications of HfAlOx gate dielectrics in oxide-based TFTs, fully solution-induced InZnO/HfAlOx TFTs have been integrated. Excellent electrical performance for InZnO/HfAlOx TFTs annealed at 450 °C has been observed, including a low operating voltage of 3 V, a saturated mobility of 5.17 cm2 V−1 s−1, a high Ion/Ioff of ∼106, a small subthreshold swing of 87 mV per decade, and a threshold voltage shift of 0.52 V under positive bias stress (PBS) for 7200 s, respectively. In addition, time dependent threshold voltage shift under PBS could be described by a stretched-exponential model, which can be due to charge trapping in the semiconductor/dielectric interface. Finally, to explore the possible application in logic operation, a resistor-loaded inverter based on InZnO/HfAlOx TFTs has been built and excellent swing characteristic and well dynamic behavior have been obtained. Therefore, it can be concluded that fully solution-driven InZnO/HfAlOx TFTs have demonstrated potential application in nontoxic, eco-friendly and low-power consumption oxide-based flexible electronics.
The Effect of Sourcing Policies on Suppliers’ Sustainable Practices

To meet the growing demand for sustainably produced products, firms must be able to source sustainably produced parts from their suppliers. In this study, we analyze how a buyer (manufacturer or retailer) can use sourcing policies to influence their suppliers to adopt sustainable processes that can meet certain sustainability criteria. We study two sustainable sourcing policies commonly observed in practice, which influence suppliers’ process decisions by committing to offer sustainable products. Under a Sustainable Preferred policy, a buyer commits to offering a sustainable product if she can source sustainably produced parts from the supplier, but will otherwise offer a conventional product. In contrast, under a Sustainable Required sourcing policy, a buyer will only offer a sustainable product, and therefore will only source from the supplier if he has adopted a sustainable process. Our results offer insights for managers by identifying how these sustainable sourcing policies influence upstream suppliers to switch to a sustainable process, and how this affects the ability of a downstream buyer to offer a sustainable product. We find that when the buyer sources from a sole supplier, the Preferred policy can deter the supplier from switching as compared to when the buyer remains noncommittal. However, only the Required policy can induce the supplier to switch. In contrast, when a buyer has multiple suppliers, the Preferred policy does not deter the supplier, but can induce him to switch to a sustainable process, similar to the Required policy. Accordingly, our results suggest that to induce the supplier to switch to a sustainable process, a buyer should adopt a Required policy when sourcing from a sole supplier, but utilize a Preferred policy when there are multiple suppliers.
Extending the family of quinolone antibacterials to new copper derivatives: self-assembly, structural and topological features, catalytic and biological activity

A new series of copper(II) compounds, [Cu(pef)2(MeOH)] (1), [Cu(pef)(bipyam)Cl] (2), [Cu(pef)(phen)Cl] (3) and [Cu(pef)(bipy)Cl] (4), bearing the quinolone family member pefloxacin (Hpef) were self-assembled in the presence (optional) of N,N′-donor heterocyclic ligands such as 2,2′-bipyridylamine (bipyam), 1,10-phenanthroline (phen), or 2,2′-bipyridine (bipy). The products were fully characterized, including single-crystal X-ray diffraction analysis of 2–4. The structures are extended into 1D (2), 2D (3), or 3D (4) networks via multiple H-bonds between the monocopper(II) units and guest water and/or methanol molecules; the latter are arranged into different types of water and hybrid water–methanol clusters. The resulting H-bonded networks were classified from a topological viewpoint, revealing diverse topologies that also include an undocumented type. Compounds 2–4 also act as homogeneous catalysts in a model oxidation reaction, namely the mild oxidation of C6–C8 cycloalkanes by H2O2 at 50 °C to give cyclic alcohols and ketones. The effects of various reaction parameters (substrate scope, temperature, and loadings of catalyst, cycloalkane, and oxidant) and selectivity features were investigated. Besides, products 1–4 also show remarkable antibacterial activity against four different microorganisms (Escherichia coli, Xanthomonas campestris, Staphylococcus aureus and Bacillus subtilis), which is superior to that of free Hpef. The interaction of the Cu(II) compounds with calf-thymus DNA was studied suggesting intercalation as the most possible binding mode. Furthermore, the interaction of the obtained copper(II) derivatives with human/bovine serum albumin was investigated by fluorescence emission spectroscopy and the corresponding albumin-binding constants were established. This study widens a limited family of transition metal pefloxacin derivatives.
Impact of integrated management of nitrogen fertilizers on yield and nutritional quality of potato

Abstract The aim of this study was to investigate the influence of different compositions of nitrogen (N) sources on yield and nutritional quality in potato cultivars (Solanum tuberosum L.). The experiment used a factorial arrangement as two factors in randomized complete block design. Factor (A) was nitrogen sources: control, 75% M + 25%V, 50% M + 50%V, 100% M, where M plots received nitrogen from mineral fertilizer and V plots received nitrogen from vermicompost. Factor (B) was potato cultivars (Sante and Savalan). In Sante cultivar, 75% M + 25%V produced the highest total and marketable yield. In Savalan, cultivar application of vermicompost in 75% M + 25%V and 50% M + 50%V increased significantly total and marketable yield as compared with 100% M. Application of vermicompost significantly decreases tuber nitrate content and increases nitrogen-use efficiency. In Savalan, cultivar 50% V + 50%M and in Sante cultivar 75% V + 25%M can effectively be used for improving yield and nutritional quality of tuber.
The amplifying effect of perceived group politicization: Effects of group perceptions and identification on anxiety and coping self‐efficacy among members of UK COVID‐19 mutual aid groups

Abstract Mutual aid groups developed and mobilized in communities across the UK and globally at the outset of the pandemic in order to support vulnerable community members with practical assistance and emotional support, with some understanding their work in political terms. This study adopted a “social cure” lens to investigate the effects of group identification and group perceptions on anxiety and coping self‐efficacy among members of UK Covid‐19 mutual aid groups. Survey data were collected from self‐identified members of these groups (N = 844) during the initial period of “lockdown” restrictions in April – May 2020. Correlational analyses showed that identification with the mutual aid group was linked to more positive group perceptions and better self‐reported psychological outcomes. Perceived group politicization showed the reverse pattern. Mixed support for the “social cure” model was evident; the effect of group identification on coping self‐efficacy (but not anxiety) was serially mediated by perceived support and collective efficacy. Perceived group politicization was a significant moderator, seeming to amplify the indirect effect of group identification on coping self‐efficacy via perceived support. Results are discussed in light of previous empirical work on the social cure and Covid‐19 mutual aid groups.

Emerging Community Pantries in the Philippines during the Pandemic: Hunger, Healing, and Hope

This research is a critical approach to the emergence of community pantries during the COVID-19 pandemic as at-once contestatory and transformative narratives, foregrounding the Filipino poor’s experience of hunger, suffering, and marginality, while also highlighting their collective hope for a better world. I began by exploring the emergence of the community pantry in the Philippines, which was prompted by the government’s inadequate response to the plight of the hungry poor due to prolonged mandatory lockdown in the National Capital Region. I then turned to Emmanuel Levinas’ concept of hunger as the basis for the ethical giving displayed in the community pantries, which is a symbolic arena where leadership is questioned and the marginalized voices of the hungry poor are both mainstreamed and articulated. I brought ethical giving into relation with the Jewish concept of Tikkun Olam as the platform for the possibility of healing wounded relations. I constructed a particular weave between the community pantry and the Filipinos’ shared experiences of hunger that touches on the ethical that can create liberating spaces for collective hope. In conclusion, I argue that this study is valuable for confronting unexamined assumptions of the relationship between hunger, healing, and hope for critical pedagogy and critical spirituality, which can have significant philosophical and theological implications.
