Evaluation of antimicrobial activity and phytochemical composition of some fractions of methanol stem bark extract of Diospyros mespiliformis

The aim of this study was to determine the active phytochemical(s) most probably responsible for microbial inhibitions, following a bioassay guided protocol. Column chromatographic fractions (AG) obtained from n-Butanol partitioned portion of stem bark extract of Diospyros mespiliformis were analyzed for phytochemical composition. These were subjected to antimicrobial activity tests on clinical isolates of Staphylococcus aureus, Streptococcus pyogenes, Pseudomonas aeruginosa, Klebsiella pneumoniae and Candida albicans. Phytochemical screening conducted on the column fraction E revealed the presence of tannins, free anthraquinones, cardiac glycosides, saponins, terpenoids, and flavonoids. The anti-microbial test results from fractions A, B, F and G, obtained showed no inhibition against most of the micro-organisms tested, while fractions C, D and E showed significant (P<0.05) activities with diameters of inhibition zone of inhibition ranging from 15.00±1.00 mm to 13.00±6.67 mm against Streptococcus pyogenes at all the concentrations tested (50, 12.5, 6.25 mg/ml equivalent to 3, 1.5 and 0.75 mg/disc). The column fraction E showed the highest inhibition zones with broader concentration dependent pattern with MIC at 12.5 mg/ml. The findings from this study showed the presence of bio-active components against Streptococcus pyogenes with relative higher potency in fraction E. Based on this findings, it can be surmised that Fraction E with significant dose-dependent activity is expected to revealed a potent broad-spectrum antimicrobial agent and thus recommended for further purification stages towards compound(s) isolation of a novel antimicrobial agent.Keywords: Antimicrobial, Diospyros mespiliformis, Phytochemical, Potency, Stem Bark
Butterflies embrace maladaptation and raise fitness in colonizing novel host

We illustrate an evolutionary host shift driven by increased fitness on a novel host, despite maladaptation to it in six separate host‐adaptive traits. Here, local adaptation is defined as possession of traits that provide advantage in specific environmental contexts; thus individuals can have higher fitness in benign environments to which they are maladapted than in demanding environments to which they are well adapted. A population of the butterfly Euphydryas editha adapted to a long‐lived, chemically well‐defended host, Pedicularis, had traditionally been under natural selection to avoid the ephemeral, less‐defended Collinsia. The lifespan of Collinsia was so short that it senesced before larvae entered diapause. After logging killed Pedicularis in clear‐cut patches and controlled burning simultaneously extended Collinsia lifespan, insect fitness on Collinsia in clearings suddenly became higher than on Pedicularis in adjacent unlogged patches. Collinsia was rapidly colonized and preference for it evolved, but insects feeding on it retained adaptations to Pedicularis in alighting bias, two aspects of postalighting oviposition preference, dispersal bias, geotaxis, and clutch size, all acting as maladaptations to Collinsia. Nonetheless, populations boomed on Collinsia in clearings, creating sources that fed pseudosinks in unlogged patches where Pedicularis was still used. After c. 20 years, butterfly populations in clearings disappeared and the metapopulation reverted to Pedicularis‐feeding. Here we show, via experimental manipulation of oviposition by local Pedicularis‐adapted and imported Collinsia‐adapted butterflies, that the highest survival at that time would have been from eggs laid in clearings by butterflies adapted to Collinsia. Second highest were locals on Pedicularis. In third place would have been locals on Collinsia in clearings, because local females maladaptively preferred senescent plants. Collinsia had been colonized despite maladaptation and, after successional changes, abandoned because of it. However, the abandoned Collinsia could still have provided the highest fitness, given appropriate adaptation. The butterflies had tumbled down an adaptive peak.
Progress and Challenges of Mercury-Free Catalysis for Acetylene Hydrochlorination

Activated carbon-supported HgCl2 catalyst has been used widely in acetylene hydrochlorination in the chlor-alkali chemical industry. However, HgCl2 is an extremely toxic pollutant. It is not only harmful to human health but also pollutes the environment. Therefore, the design and synthesis of mercury-free and environmentally benign catalysts with high activity has become an urgent need for vinyl chloride monomer (VCM) production. This review summarizes research progress on the design and development of mercury-free catalysts for acetylene hydrochlorination. Three types of catalysts for acetylene hydrochlorination in the chlor-alkali chemical industry are discussed. These catalysts are a noble metal catalyst, non-noble metal catalyst, and non-metallic catalyst. This review serves as a guide in terms of the catalyst design, properties, and catalytic mechanism of mercury-free catalyst for the acetylene hydrochlorination of VCM. The key problems and issues are discussed, and future trends are envisioned.
International Finance Trilemma as a Tool for Balanced Development of an Economy

International financial trilemma is a challenge of balancing the governmental policies ensuring healthy financial sector for facilitating economic development of a country. The scientific purpose of the paper is to develop a model of the international financial trilemma, defining the three key pillars of the international financial trilemma, the corresponding relevant metrics of economy, as well as describing expansion of financial technology as a disruptive element on a trilemma balance. Taking into account the experience of other researches of trilemma concept, analogically to the Energy Trilemma index, the authors developed the trilemma concept for the financial sector. The paper proposes determining the Financial trilemma index basing it on the following pillars: financial stability, financial inclusion and transparency. The authors analyse FinTech services as disruptive element affecting the International Financial trilemma index. As statistical basis of the financial trilemma and its building blocks the set of data from publicly available databases, such as the Global Competitiveness index, the Financial Development index, Global Findex and Doing Business is determined. The generally accepted quantitative and qualitative methods of economic science, inter alia comparative analysis, parameter estimation, grouping, economically mathematical modelling, synthesis, inductive, deductive and logically constructive methods have been used for the research. The financial trilemma index could be used as a tool for modelling an impact assessment of planned policy actions, as well as for developing determined steps for rising values of particular trilemma elements.
Fostering STEAM through challenge‐based learning, robotics, and physical devices: A systematic mapping literature review

Nowadays, companies are demanding better‐prepared professionals to succeed in a digital society, and the acquisition of Science, Technology, Engineering, Arts, and Mathematics (STEAM)‐related competencies is a key issue. One of the main problems in this sense is how to integrate STEAM into the current educational curricula. This is not something related to a subject or educational trend but rather to new methodological approaches that can engage students. In this sense, such active methodologies that apply mechatronics and robotics could be an interesting path to pursue. Given this context, the first necessary task in evaluating the potential of this approach is to understand the landscape of the application of robotics and mechatronics in STEAM Education and how active methodologies are applied in this sense. To carry out this analysis in a systematic and replicable manner, it is necessary to follow a methodology. In this case, the researchers employ a systematic mapping review. This paper presents this process and its main findings. Fifty‐four studies have been selected out of 242 total studies analyzed. From these, beyond obtaining a clear vision of the STEAM landscape regarding project topics, we can also conclude that robotics and physical devices have been applied successfully with collaborative methodologies in STEAM Education. Regarding conclusions, this paper shows that robotics and mechatronics applied with active methodologies is to be a good means to engage students in STEAM disciplines and thus aid the acquisition of what is commonly known as “21st‐century skills. ”
A wide input power range rectenna for energy harvesting and wireless power transfer applications

This article describes a novel rectifying‐antenna design with extended input power range operating at 2.4 GHz for both ambient wireless energy harvesting and wireless power transmission (WPT) systems. The rectenna consists of a 2 × 2 fractal antenna array and a rectifier circuit with a high‐power conversion efficiency (PCE) in a wide input power range. This circuit contains two conversion stages based on two different Schottky diodes, and a third stage that dissipates the unconverted input power, which can disturb the harvesting process. These three stages are controlled by a power management block based on circulators, that direct the input power to the adequate stage according to its power range. A prototype of the proposed harvesting system is fabricated and experimentally validated. The measurement results confirm the wide input power range behavior of the designed rectenna with a relatively constant and high PCE (between 58% and 67%) for a power density ranging from 4 to 252 μW/cm2. The proposed solution can be successfully used for both ambient energy harvesting and WPT systems.
Green Rust: Its Electrochemical Generation, Characterization, and Implications

Abstract : Green rust is an important intermediate in oxidative transformation of Fe(II) phase. This unstable compound contains a mixture of ferrous and ferric hydroxides that belong to a family of minerals known as layered double hydroxides (LDH). Its general formula is [FeII (6-x) FeIII x (OH)12]x+[Ax/n- *yH2O] x-, where A is an n-valent anion mainly Cl-, CO3 (-2) and SO4 (-2) , and in which either the bivalent or the trivalent iron can be replaced for other trivalent or bivalent metal ions. It was first identified as corrosion product, later in soils as a product of interactions between microbes and metals in soils. Due to its high reactivity, it is used in the reduction of organic and inorganic compounds, As removal, and the treatment of acid mine drainage. In this paper, we described the method of electrochemical generation of green rust, its characterization by XRD, SEM and FTIR and its implications to electrocoagulation.
Verification of ingroup morality promotes willingness to participate in collective action for immigrants’ rights

Three experiments tested whether verification of ingroup morality increases engagement in collective action in favor of immigrants’ rights. To that end, participants were exposed to (a) verifying, (b) negatively discrepant, (c) enhancing, or (d) no feedback about the morality of their group in general (Studies 1–2) or specifically in matters of corruption (Study 3). Results show that those who received verifying feedback of their group’s morality were more willing to engage in collective action than those who received negative or no feedback. These effects seemed to be mediated by increased anger over immigrants’ disadvantage and positive attitudes towards them. Critically, enhancing feedback exerted similar effects as verifying feedback, although the latter yielded more stable and consistent results across the studies. These results suggest that appeals to collective ingroup morality can be effective to promote immigrants’ rights, especially when members of the host society feel that others consider them as moral as they perceive themselves.
Predicting Hollow Heart Incidence in Triploid Watermelon (Citrullus lanatus)

In triploid (seedless) watermelon [Citrullus lanatus var. lanatus (Thunb. Matsum. and Nakai)], hollow heart (HH) is a disorder that is expressed as a crack in the center of the fruit that expands to an open cavity. Although HH incidence and severity is part of a screening process for marketable watermelon fruit during cultigen evaluations, HH incidence is highly variable with growing season, even when the best cultural practices are used. Placental tissue firmness is also measured because firmness is related to the marketability of watermelon and may be related to HH. Genetic and environmental factors can influence watermelon HH development, including plant genetics, pollen amount and viability, pollinator activity, and temperature and rainfall fluctuations. We used seedless watermelon cultigen evaluation data collected over 3 years (2012–14) to determine the relationship between germplasm HH and tissue firmness. Transplanted watermelon representing 30 to 44 cultigens per year were grown at the Central Crops Research Station, Clayton, NC, and interplanted with pollenizers ‘Ace’ and/or ‘SP-6’. Harvested fruit were cut length-wise and rated for HH incidence and severity. Flesh firmness was determined by a handheld penetrometer at five locations in the flesh (stem end, top side, ground spot, blossom end, and heart). A common cultigen subset, consisting of 13 cultigens that were grown in all three experiments, was used for analysis of HH severity and incidence, and placental firmness. The presence of HH was negatively correlated with tissue firmness in both the large multiyear cultigen set (R2 = −0.32; P = 0.0001) and the common cultigen set (R2 = −0.78; P = 0.0001). Cultigens with lower watermelon tissue firmness values had higher HH incidence and severity. By using multiyear cultigen studies and logistic regression, we were able to detect trends for cultigen susceptibility to this highly variable disorder. Using logistic regression, the probability of HH development was highest for ‘Bold Ruler’, ‘Liberty’, and ‘Affirmed’, and lowest for ‘Maxima’ and ‘Captivation’. The identification of cultigens with a tendency for higher or lower rates of HH will be useful for further research of the causes of HH. Measurements of placental flesh firmness may be useful indicators of susceptible cultigens.
Infusing Multiculturalism, Identity, and Social Justice in Asynchronous Courses

Introduction: Creating a multiculturally aware and inclusive class is critical with students. The lack of face-to-face contact with asynchronous courses limits instructors’ ability to form relationships with students. A myriad of teaching research provides strategies for incorporating multiculturalism, social justice, and identity into synchronous courses; however, considerably less research exists with asynchronous courses. Statement of the Problem: The purpose of the current article is to provide strategies for incorporating multiculturalism and issues of identity into asynchronous courses with a social justice lens. Literature Review: I review several published topical and review articles and offer suggestions and strategies that I have used in my own courses and/or in courses I have been involved with. Teaching Implications: I discuss the importance of incorporating multiculturalism and identity while maintaining justice in asynchronous courses. Moreover, I offer suggestions and strategies for doing so, from prior to class starting to navigating instances of microaggressions. Conclusion: This article builds off and infuses components of counseling psychology into the teaching of psychology to advance instructors’ cultural awareness, skills, and competence with asynchronous online courses.

Domestication changes in Japanese quail (Coturnix japonica): a review

SUMMARY Domestic quail (Coturnix japonica domestica) is a domesticated gallinaceous bird that originated in East Asia with ancestor the wild Japanese quail (Coturnix japonica). Subsequently, to domestication, quail have undergone a number of morphological, ethological and productive changes that make them quite different from those of their wild ancestors. These reflect greater intraspecific differences than even in the differences between species in the genus Coturnix. Unlike the wild quail, a variety of other plumage colours are seen in the domestic quail, the most popular being variations of golden, tuxedo, extended brown and recessive white. The average live weight of the wild Japanese quail varies within 85–110 g, whereas the domestic quail are about 45% to more than 250% heavier, depending on their productive type. Major differences are visible in the migratory, sexual, nesting and brooding behaviour, and other ethological reactions such as vocalisation, mating calls, aggression and fighting. A number of productive parameters have been affected by domestication. Wild Japanese quail lay about 5–14 eggs per clutch, with 2–3 broods per year. Domestic quail could lay more than 250 eggs per year with average egg weight increase of 20% in egg production to 100% in meat production compared to their ancestors. This review summarises how domestication and human impact affect a number of features, significantly altering the Japanese quail. The aim is to emphasise the changes that occurred during the domestication of Japanese quail, supporting the proposal of using the term ‘domestic quail’ (Coturnix japonica domestica).

Optimizing the Huff ‘n’ Puff Gas Injection Performance in Shale Reservoirs Considering the Uncertainty: A Duvernay Shale Example

Recent studies have indicated that huff ‘n’ puff (HNP) gas injection has the potential to recover an additional 30 to 70% oil from multifractured horizontal wells in shale reservoirs. Nonetheless, this technique is very sensitive to production constraints and is impacted by uncertainty related to measurement quality (particularly frequency and resolution) and lack of constraining data. In this paper, a Bayesian workflow is provided to optimize the HNP process under uncertainty using a Duvernay shale well as an example. Compositional simulations are conducted that incorporate a tuned pressure/volume/temperature (PVT) model and a set of measured cyclic injection/compaction pressure-sensitive permeability data. Markov-Chain Monte Carlo (MCMC) is used to estimate the posterior distributions of the model uncertain variables by matching the primary production data. The MCMC process is accelerated by using an accurate proxy model (kriging) that is updated using a highly adaptive sampling algorithm. Gaussian processes are then used to optimize the HNP control variables by maximizing the lower confidence interval (μ-σ) of cumulative oil production (after 10 years) across a fixed ensemble of uncertain variables sampled from posterior distributions. The uncertain variable space includes several parameters representing reservoir and fracture properties. The posterior distributions for some parameters, such as primary fracture permeability and effective half-length, are narrower, whereas wider distributions are obtained for other parameters. The results indicate that the impact of uncertain variables on HNP performance is nonlinear. Some uncertain variables (such as molecular diffusion) that do not show strong sensitivity during the primary production strongly impact gas injection HNP performance. The results of optimization under uncertainty confirm that the lower confidence interval of cumulative oil production can be maximized by an injection time of approximately 1.5 months, a production time of approximately 2.5 months, and very short soaking times. In addition, a maximum injection rate and a flowing bottomhole pressure around the bubblepoint are required to ensure maximum incremental recovery. Analysis of the objective function surface highlights some other sets of production constraints with competitive results. Finally, the optimal set of production constraints, in combination with an ensemble of uncertain variables, results in a median HNP cumulative oil production that is 30% greater than that for primary production. The application of a Bayesian framework for optimizing the HNP performance in a real shale reservoir is introduced for the first time. This work provides practical guidelines for the efficient application of advanced techniques for optimization under uncertainty, resulting in better decision making.

Improving PAPR performance of filtered OFDM for 5G communications using PTS

The filtered orthogonal frequency division multiplexing (F‐OFDM) system has been recommended as a waveform candidate for fifth‐generation (5G) communications. The suppression of out‐of‐band emission (OOBE) and asynchronous transmission are the distinctive features of the filtering‐based waveform frameworks. Meanwhile, the high peak‐to‐average power ratio (PAPR) is still a challenge for the new waveform candidates. Partial transmit sequence (PTS) is an effective technique for mitigating the trend of high PAPR in multicarrier systems. In this study, the PTS technique is employed to reduce the high PAPR value of an F‐OFDM system. Then, this system is compared with the OFDM system. In addition, the other related parameters such as frequency localization, bit error rate (BER), and computational complexity are evaluated and analyzed for both systems with and without PTS. The simulation results indicate that the F‐OFDM based on PTS achieves higher levels of PAPR, BER, and OOBE performances compared with OFDM. Moreover, the BER performance of F‐OFDM is uninfluenced by the use of the PTS technique.
