Essential oil from Piperaceae as a potential for biopesticide agents: a review

This review is aimed to present information on the properties of Piperaceae which can be potentially used as a biopesticide. The chemical compounds involved in were different as each species consist of different amount of secondary metabolites which then leads to different properties. In recent years, several reports have been published regarding the composition and the biological activities of the essential oils of Piper species. These studies have highlighted the existence of marked chemical differences among oils extracted from different species or varieties. Analysis of volatile constituents from Piperaceae species has revealed the presence of monoterpenes, sesquiterpenes and arylpropanoids that have shown interesting biological properties including cytotoxic, fungistatic, insecticide, molluscicidal, antioxidant and antimicrobial activities. Essential oils are natural complex secondary metabolites characterized by strong odour, volatility and have generally lower density than water. Due to their volatility, essential oils are environmentally non-persistent. On top of that, essential oils are ‘generally recognized as safe’ by the United States Food and Drug Administration (FDA). Since technology has become more advanced, people started to replace synthetic pesticide with bio-pesticide. The demand for EO has increased as it has biological properties that can be used to replace synthetic pesticide
Assessment of the therapeutic potential of anti-miR 24 and anti-miR 34 in cardiac diseases

Purpose: To study the therapeutic effects of anti-miR-24 and anti-miR-34 in cardiac diseasesMethods: H9c2 rat cardiomyocyte cell lines were transfected with the synthetic oligonucleotides antimiR-24 and anti-miR-34 which reduced the expressions of miR-24 and miR-34. Proliferation assay, real time-polymerase chain reaction (RT-PCR) and immunoblotting were carried out to determine the effect of the transfections on cardiomyocyte proliferation, expressions of miR-24 and miR-34, as well as expressions of the target genes, TGF-β1 and E2F3.Results: The proliferation ability of the transfected cells was decreased significantly, relative to negative control. In contrast, percentage apoptosis was higher in the negative control group than in transfected cells. The expression profiles of anti-miR-24 and anti-miR-34 were significantly reduced, when compared to negative control. These results were further confirmed using immunoblot which revealed that the expression of the target genes, TGF-β1 and E2F3, were upregulated in the transfected cells.Conclusion: These results suggest that the synthetic oligonucleotides (anti-miR-24 and anti-miR-34) might be useful in developing therapeutic drug targets for cardiac diseases by suppressing the expressions of miR-24 and miR-34. Keywords: H9c2rat cardiomyocyte miRNA, Anti-miR-24, Anti-miR-34, Cardiac diseases
In vitro antileishmanial activity and phytochemical analysis of Casearia javitensis Kunth (Salicaceae)

The objective of this study was to carry out phytochemical analysis of the bark extract of Casearia javitensis and to evaluate its antipromastigote activity against Leishmania amazonensis. The ethanol extract (EE) was fractionated in open-column chromatography to obtain the hexane (FrHex), dichloromethane (FrDcm), ethyl acetate (FrAcOET) and methanol (FrMeOH) fractions. The EE and its fractions were analyzed by thin layer chromatography (TLC). FrDcm was analyzed in high performance liquid chromatography with diode array detection (HPLC-DAD). The antipromastigote assay of Leishmania amazonensis and the cytotoxicity test against the acute monocytic leukemia cell line (THP-1) were performed by the MTT colorimetric assay. The phytochemical profile in TLC detected terpenes in all samples. However, in the ultraviolet spectrum (HPLC-DAD) for FrDcm suggested the presence of a phenolic compound. FrHex and FrDcm showed antipromastigote activity (IC50 = 116.6 ± 0.9 and 59.4 ± 1.1 μg mL-1, respectively) and low cytotoxicity (CC50 = 333.4 ± 3.2 and 241.2 ± 1.9 μg mL-1, respectively). The selectivity index for FrDcm was 4.1. We conclude that the FrDcm of C. javitensis has potantial as a leishmanicide, and this activity may be related to the presence of phenolic compound.

Electrocatalytic Hydrogenation of Phenol over Platinum and Rhodium: Unexpected Temperature Effects Resolved

Both electrocatalytic hydrogenation (ECH) and thermal catalytic hydrogenation (TCH) of phenol by Pt and Rh show a rollover in rate with increasing temperature without changing the principal reaction pathways. The negative effect of temperature for aqueous-phase phenol TCH and ECH on Pt and Rh is deduced to be from dehydrogenated phenol adsorbates, which block active sites. ECH and TCH rates increase similarly with increasing hydrogen chemical potential whether induced by applied potential or H2 pressure, both via increasing H coverage, and indirectly by removing site blockers, a strong effect at high temperature. This enables unprecedented phenol TCH rates at 60–100 °C.
Gain‐scheduled steering control for autonomous vehicles

This study presents a linear parameter varying (LPV) approach for the lateral control of autonomous vehicles, in order to take into account the whole operating domain of longitudinal speeds, as well as the variation of the look-ahead distance. Combining a dynamical vehicle model with look-ahead dynamics, together with an identified actuator model including an input delay, the closed-loop performances can be achieved and the tracking capabilities can be improved for every speed. This is obtained in particular through ad hoc representation of the look-ahead time as a parameter-dependent function. An H ∞ LPV control problem is formulated considering parameter-dependent weighting functions, allowing the control adaptation for all speeds. The synthesis is performed using the gridding approach, in order to account for varying parameter rate. The proposed steering control system has been implemented on a real electric Renault Zoe car. The performances are therefore assessed experimentally on a real test track with a varying longitudinal speed profile, and compared with a classical LPV polytopic controller, which proves the advanced lane-tracking capabilities of the proposed methodology.

Facilitating Access to Higher Education for People Seeking Asylum in Australia: Institutional and Community Responses

Higher education remains unattainable for many people seeking asylum in Australia, where temporary visa status renders individuals ineligible for a range of government services including assistance with financing tertiary study. Many universities have responded by offering scholarships and other essential supports; however, our research indicates the challenges associated with studying while living on a temporary visa can affect the success of educational assistance. Here we highlight the importance of scholarships and other supports for facilitating access to tertiary study, particularly given the continuation of restrictive government policies, and identify the need for people seeking asylum to inform institutional and community responses. **** Note that the pagination of this article has been adjusted due to resolving a production error in another article in this issue. ***
A New Diversity Panel for Winter Rapeseed (Brassica napus L.) Genome-Wide Association Studies

A diverse population (429 member) of canola (Brassica napus L.) consisting primarily of winter biotypes was assembled and used in genome-wide association studies. Genotype by sequencing analysis of the population identified and mapped 290,972 high-quality markers ranging from 18.5 to 82.4% missing markers per line and an average of 36.8%. After interpolation, 251,575 high-quality markers remained. After filtering for markers with low minor allele counts (count > 5), we were left with 190,375 markers. The average distance between these markers is 4463 bases with a median of 69 and a range from 1 to 281,248 bases. The heterozygosity among the imputed population ranges from 0.9 to 11.0% with an average of 5.4%. The filtered and imputed dataset was used to determine population structure and kinship, which indicated that the population had minimal structure with the best K value of 2–3. These results also indicated that the majority of the population has substantial sequence from a single population with sub-clusters of, and admixtures with, a very small number of other populations. Analysis of chromosomal linkage disequilibrium decay ranged from ~7 Kb for chromosome A01 to ~68 Kb for chromosome C01. Local linkage decay rates determined for all 500 kb windows with a 10kb sliding step indicated a wide range of linkage disequilibrium decay rates, indicating numerous crossover hotspots within this population, and provide a resource for determining the likely limits of linkage disequilibrium from any given marker in which to identify candidate genes. This population and the resources provided here should serve as helpful tools for investigating genetics in winter canola.
ELECTROLESS DEPOSITION OF PALLADIUM USING HYPOPHOSPHITE AS A REDUCING AGENT

PLATING & SURFACE FINISHING Electroless deposition of flat and shiny coatings and powders of Pd-P alloy from an alkaline solution containing PdCl 2 as a source of Pd(II) ions and hypophosphite as a reducing agent was investigated. The results showed that the rate of deposition increased as temperature increased. On the other hand, an increase in pH led to a decrease in the rate of palladium deposition. Deposited Pd-P films and powders exhibited an amorphous structure. According to the DSC analysis, recrystallization of these materials was observed at a temperature of about 290 °C. In the recrystallized sample, phases such as Pd 6 P and elemental palladium were identified.
Imaging of Rydberg Impurities in an Ultracold Atomic Gas

This thesis investigates how a single highly excited atom, called Rydberg atom, can be optically imaged. Direct detection methods based on the scattering of light are hardly applicable due to the small scattering rate of the ground to Rydberg state transition. Instead, a cloud of ground state atoms, normally absorptive, is rendered transparent using electromagnetically induced transparency (EIT), involving an auxiliary probe Rydberg state. The cloud acts as a contrast medium, whose optical response is locally perturbed by the strong Rydberg-Rydberg interaction between the probe and the Rydberg impurity which we want to detect. This perturbation restores absorption within a small volume around the impurity, readily detected and spatially resolved on a camera. We call this technique Interaction Enhanced Imaging (IEI). To implement IEI we characterize the optical response of the EIT contrast medium in absence of interactions. By combining measurements of the spatially resolved optical spectrum and of the total Rydberg atom number, we can reconstruct the full one-body density matrix of the three-level system. Next, we excite |nS> or |nP> states and, using IEI, we demonstrate spatially resolved imaging, enabling us to study dipolar energy transport. To reach single impurity sensitivity we investigate our current detection fidelity and characterize the signal and noise contributions in IEI. We model our interacting system, finding good agreement with experimental data. Based on this model, we predict combinations of Rydberg states for which single-shot single impurity sensitivity should be possible in future experiments.

Growth and quality parameters of Tea (Camellia sinensis) mediated by arbuscular mycorrhizal fungi

Arbuscular mycorrhizal fungi (AMF) inoculation not only increases the growth but also improves the quality of many commercial plants. Tea (Camellia sinensis) plants were grown on different growth medium (with and without AMF inoculation) and the chemical properties of the leaves were assayed and compared. The growth media were sterilized soil with AMF, sterilized soil, natural soil inoculated with AMF, natural soil, and natural soil in natural condition with AMF. The highest root colonization (23 %) was found in tea plants grown on natural soil with AMF, whereas no colonization was found in the sterilized soil treatment. The highest level of leaf chlorophyll-a (2.74±0.06 μg.mL-1), chlorophyll-b (1.77±0.03 μg.mL-1) and carotenoid (0.35±0.01 μg.mL-1) contents were found in tea plants grown on natural soil under natural condition with AMF. The highest polyphenol concentration (64.46 mg.L-1) was found in natural soil inoculated with AMF whereas the lowest (38.09 mg.L-1) was recorded in sterilized soil. The highest contents of tannin (30.34 mg.mL-1) and reducing sugar (46.61 mg.L-1) were recorded in plants grown on natural soil under natural condition with AMF and the lowest values (21.22 mg.mL-1, 33.16 mg.L-1, respectively) in sterilized soil treatment. Though antioxidant properties (% scavenging effect) did not differed due to treatments, the highest IAA (Indole-3-acetic acid) concentration (3.16 μg.mL-1) was recorded in tea plants grown on natural soil under natural condition with AMF. The study concludes that AMF inoculation improves the quality of tea leaves.
How the Anonymous Feature of Audience Response System Influences the Interactions of Students by Different Types of Questions

The Audience Response System (ARS) has been found effective among educators as a good way of using technology to increase participation, involvement, and engagement. Many researchers suggest that the benefits of ARS on students' participation and interactions are associated with its anonymity. ARS questions and using questing strategies during an ARS-based learning activity are also regarded as crucial factors influencing the effectiveness of the implementation of ARS in a class. To examine the influences of the anonymous feature of ARS on students' interactions in light of different types of questions, a post-test only quasi-experiment was conducted with 17 college students. Findings suggested that in a face-to-face class, when given the option, the anonymous feature of ARS was increasingly used by students in their interactions, and the average class interaction was improved. Meanwhile, the effect of the anonymous feature of ARS on students' interactions in class differed according to the types of questions. The anonymous feature might be more useful and effective when students interact with Evaluate questions. While for Create or Apply questions, students preferred real name interactions. Implications for future research were provided for effectively using ARS to facilitate learning.
Plasma‐catalytic reforming of biogas over supported Ni catalysts in a dielectric barrier discharge reactor: Effect of catalyst supports

In this study, plasma-catalytic reforming of simulated biogas for the production of value-added fuels and chemicals (e.g., H2) has been carried out in a coaxial dielectric barrier discharge (DBD) plasma reactor. The influence of four Ni catalysts (Ni/γ-Al2O3, Ni/MgO, Ni/SiO2, and Ni/TiO2) on the plasma-catalytic biogas reforming has been investigated in terms of the conversion of reactants, the yield and selectivity of target products, the carbon deposition on the catalysts, and the energy efficiency of the plasma-catalytic process. The use of plasma combined with these Ni catalysts enhanced the performance of the biogas reforming. A maximum CO2 conversion of 26.2% and CH4 conversion of 44.1% were achieved when using the Ni/γ-Al2O3 catalyst at a specific energy density (SED) of 72 kJ l−1. Compared to other Ni catalysts, placing the Ni/γ-Al2O3 catalyst in the DBD produced more syngas and C3C4 hydrocarbons, but less C2H6. The lowest energy cost (EC) for biogas conversion and syngas production, as well as the highest energy efficiency and fuel production efficiency (FPE), were achieved when using the Ni/γ-Al2O3 catalyst in the plasma process. The Ni/γ-Al2O3 catalyst also showed the lowest surface carbon deposition of 3.8%, after catalysing the plasma biogas reforming process for 150 min at a SED of 60 kJ l−1. Compared to other Ni catalysts, the enhanced performance of the Ni/γ-Al2O3 catalyst can be attributed to its higher specific surface area, higher reducibility and more, stronger basic sites on the catalyst surface.
Public procurement in Big Science: politics or technology? The case of CERN

Public procurement from Big Science Centers (BSCs) yields a variety of spillover effects that can ultimately have growth enhancing consequences for their Member States (MS). We study the determinants of procurement for the biggest research infrastructure ever built: the Large Hadron Collider (LHC) at CERN. A unique database of firms that have registered to become industrial partners of the LHC program allows us to estimate the determinants for potential suppliers of receiving an order from CERN. We compare the relative weight of firms’ technological features and CERN’s procurement rules aimed at securing a juste retour for its MS. Although in accordance to CERN’s procurement rules our results highlight the role of both technological factors and political constraints, we also show the existence of a premium toward Swiss and French firms. We document that the constraints related with the achievement of a juste retour affect—directly or indirectly—the procurement policy of many European BSCs and international bodies whose budget is financed by the public funds of their MS. Therefore, our results have policy implications that go beyond our empirical application.
Optical and photodetector properties of stripe-like InS crystal

Stripe-like InS crystals have been grown by physical vapor transport method. Transmission electron microscopy, scanning electron microscopy, optical microscope and Raman measurement characterize the outline shape and orthorhombic structure of the as-grown InS. A prototype photo-metal-semiconductor-field-effect transistor (Photo-MESFET) has been made by a stripe and layer-like InS crystal with Ag for the drain and source contacts and Au for the gate metal. Transmittance results determine its band gap, and the value of about 1.78 eV renders InS more sensitive to near infrared (NIR) than to visible-light optical response. VSD–ISD measurements show p-channel conduction behavior of the InS Photo-MESFET. Under the illumination of a tungsten lamp of power density ∼3 mW cm−2, the transconductance gain reaches gm = 0.272 ± 0.005 μA V−1.
Interventions to Deliver Vaccination to, and Improve Vaccination Rates in, People who are Homeless

Background: In comparison to the general population, people who are homeless have poorer health and health-related outcomes, including for vaccine-preventable diseases. Vaccination is safe, effective and cost-effective, and many vaccination guidelines specifically recommend vaccination in people who are homeless. This systematic review will identify interventions which are effective in delivering vaccination to, and/or at improving vaccination rates in, people who are homeless. Methods/Design: This systematic review is presented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches will be undertaken on eight electronic databases, using combinations of search terms and subject headings or index terms. Citation chaining will also be undertaken. Literature will be screened for relevance against inclusion/exclusion criteria firstly by title/abstract and secondly by full text. The selected studies will be assessed for quality using an evidence-based tool appropriate to their methods. Data relevant to the topic will be extracted and examined using meta-analysis and narrative synthesis. Discussion: This systematic review will address an important gap in the literature about vaccination in people who are homeless. The review’s findings are particularly relevant considering the current coronavirus disease (COVID-19) pandemic, which is likely to be managed through vaccination.
