Stretchable and Soft Electroadhesion Using Liquid‐Metal Subsurface Microelectrodes

Electroadhesion is an attractive mechanism to electrically modulate adhesion to surfaces. Electroadhesion arises from the interaction of electric fields with conductive or dielectric materials. Electroadhesion devices consist of in‐plane, interdigitated electrodes that generate out‐of‐plane electric fields, which increase adhesion with target surfaces. To date, these electrodes have predominantly been composed of carbonaceous materials. Here, liquid metal is utilized to create the electrodes in silicone substrates. Liquid metal can be patterned in a variety of unique ways, including microfluidic injection, spray deposition, or printing. These electrodes have nearly unlimited deformation in soft and stretchable substrates while maintaining metallic conductivity. The experimental results show that stretching improves electroadhesion performance due to the changes in geometry of the electrodes and insulation layer, whose behaviors are theoretically predictable. The use of liquid‐filled, sub‐surface microchannels can help to maintain contact between the elastomer and substrate during peeling due to the surface stresses caused by the capillary pressure. This approach to electroadhesion can be implemented in ultra‐stretchable and soft substrates, including those used in soft robotics, due to the inherently compliant and deformable electrical conductivity of the liquid metal electrodes.
Advertisers could come for your dreams, researchers warn

Now, a group of 40 dream researchers has pushed back with an open letter calling for regulations on "dream incubation advertising. " They worry companies might one day use smart speakers like the Amazon Echo to detect people9s sleep stages and play back sounds that could influence their night visions and behaviors.
Uma Juventude à Flor da Pele: o dilema de adolescer ou adoecer

Resumo: O crescimento das lesões de pele autoprovocadas e a elevação das taxas de suicídio em faixas etárias mais jovens indicam um profundo mal-estar no adolescer contemporâneo. A tendência a medicalização de diversos aspectos da vida tem produzido uma abordagem reducionista desses fenômenos, dificultando o estabelecimento de fronteiras entre o adolescer e o adoecer. A pandemia do Covid-19 acentuou o sofrimento psíquico entre os adolescentes. Como alternativa a medicalização das crises subjetivas é necessário dar voz aos jovens para que possam transformar a angústia e o desalento em participação ativa no processo de mudanças da sociedade.
Is Ethicality Itself a Boundary Condition for Ethicality: The Complementary Role of Employees’ Exchange Ideology and Moral Awareness in Restricting the Effect of Ethical Leadership in Reducing Workplace Deviance

Ethical leadership (EL) seems to be effective in reducing workplace deviance, questions remain as to whether its benefits are consistent across all situations. Specifically, whether its effectiveness remained in an already ethical environment. In this investigation, we explore two important boundary conditions of ethical leadership that are themselves related to ethicality. We first explore how employees’ moral awareness (MA) may lessen the need for ethical leadership. Drawing on substitutes for leadership theory, we suggest that when individuals already possess a heightened level of moral awareness, ethical leadership’s role in reducing deviant actions may be reduced. We also contended that Employees’ Exchange Ideology - the strength of an employee’s belief that the work effort should depend on treatment by the organization- also reduces EL effectiveness. This norm of reciprocity may not be ethical, as the leader’s positive or negative efforts towards employees may divert them from doing what is morally right to reciprocate. However, not all individuals value reciprocity to the same degree, hence higher Employees’ Exchange Ideology (EEI) may be another boundary condition of EL effectiveness. We conceptualize this framework by modifying Gok et. al. (2017) model to add Employees’ Exchange Ideology as a moderating factor along with Moral Awareness. Workplace Deviance was measured by organizational directed deviance (OD) and supervisor directed deviance (SD). Empirical validity was established by conducting a survey using a close-ended questionnaire. Data was collected from 310 employees working in different organizations in Pakistan and was analyzed using confirmatory factor analysis and structured equation modeling. Results indicated a significant negative complementarity of EEI, in the effect of EL on both dimensions of workplace deviance. This suggested, higher EEI seems to limit the effect of EL on organizational and supervisor-directed deviance. However, the moderating effect of MA was not substantiated for Pakistan. EEI also seems to have a positive effect on both OD and SD, while, SD seems to have a positive effect on OD. Interestingly, EL seems to be causing rather than reducing both OD and SD in the Pakistani environment.
Utilization of Foxtail Millet Starch Film Incorporated with Clove Leaf Oil for the Packaging of Queso Blanco Cheese as a Model Food

Clove leaf oil was incorporated into foxtail millet starch (FMS) for developing an active packaging material with antimicrobial and antioxidant activities. The FMS films that contained clove leaf oil exhibited changes in tensile strength (6.78–4.00 MPa) and elongation at break (66.26–99.48%) with the addition of increasing concentrations of the essential oil, and possessed ultraviolet-light barrier properties. Moreover, the FMS films that contained clove leaf oil inhibited the growth of Listeria monocytogenes. The addition of clove leaf oil resulted in excellent ABTS and DPPH radical-scavenging activity of the films. The FMS film packaging that contained 1% clove leaf oil led to a decrease in the population of Listeria monocytogenes in queso blanco cheese by 1.19 log CFU g−1 after storage for 24 days, compared with that in the control samples. In addition, the concentration of thiobarbituric acid reactive substances decreased by 54%. Thus, these results suggest that the FMS films that contain clove leaf oil can be used as a new packaging material for enhancing the shelf life of queso blanco cheese.
Exploring Medical Students' and Faculty's Perception on Artificial Intelligence and Robotics. A Questionnaire Survey

Over the last decade, the emerging fields of artificial intelligence (AI) and robotics have been introduced in medicine, gaining much attention. This study aims to assess the insight of medical students and faculty regarding AI and robotics in medicine. A cross-sectional study was conducted among medical students and faculty of the University of Nicosia. An online questionnaire was used to evaluate medical students’ and faculty’s prior knowledge and perceptions toward AI and robotics. Data analysis was carried out using SPSS software, and the statistical significance was assumed as p value < 0.05. Three hundred eighty-seven medical students and 23 faculty responded to the questionnaire. Students who were “familiar” with AI and robotics stated that these breakthrough technologies make them more enthusiastic about working in their speciality of interest ( p value = 0.012). Also, students (59.9%) and faculty (47.8%) agreed that physician’s opinion should be followed when doctors’ and AI’s judgment differandthatthedoctorinchargeshouldbeliableforpossibleAI’smistakes(38.8%students:47.7%faculty).

Low-Profile Planar Dielectric Polarizer Using High-Dielectric-Constant Material and Anisotropic Antireflection Layers

A novel planar dielectric polarizer made of a low-profile high-dielectric-constant material is proposed. Two anisotropic antireflection layers are used on both sides to provide impedance transformation and anisotropy simultaneously. The proposed design uses a high-dielectric-constant material to reduce the overall thickness without severe reflections. The unit cells of the middle layer and the antireflection layer use separate periods for better adapting to the fabrication limitation. A polarizer prototype centered at 24 GHz is designed, fabricated, and measured. The prototype is 3-D-printed by commercial fused-deposition-modeling (FDM) technology using a material with a dielectric constant of 10. Experiments show that the prototype has a 25% operating bandwidth and a thickness of <inline-formula> <tex-math notation="LaTeX">$0.52\lambda _{0}$ </tex-math></inline-formula> (<inline-formula> <tex-math notation="LaTeX">$\lambda _{0}$ </tex-math></inline-formula> is the wavelength in the free space). The design methodology widens the choice for material selection and reduces the dimensions of the dielectric polarizer.
PHYTOCHEMICAL AND PROXIMATE ANALYSES OF DIFFERENT PARTS OF AZADIRACHTA INDICA A. JUSS

This study was conducted to assess the phytochemical and proximate contents of different parts of Azadirachta indica. The dried and powdered fruit pulp, seed, leaf, stem, stem bark, root and root bark of A. indica were subjected to various sample preparation stages using standard laboratory procedures for determination of phytochemical and proximate composition in the test plant parts. Analysis of Variance (ANOVA) was employed to test for significance. Means were separated using Duncan’s New Multiple Range Test (DNMRT). The results of the study revealed that there were marked differences (P<0.05) in the phytochemical and proximate contents of the fruit pulp, seed, leaf, stem, stem bark, root and root bark of A. indica. Alkaloid was the highest phytochemical compound in the leaf of the test plant. Alkaloid contents of the leaf and root bark showed the highest and equal values (3.42+ 3.45) respectively, while steroid showed the lowest content in fruit pulp (0.15+ 0.17). Carbohydrate content of the fruit pulp showed the highest value (65.52+ 66.13), while the least was fat content of the root (0.42+ 0.45). This study suggests that the phytochemical values and nutritional components of fruit pulp, seed, leaf, stem, stem bark, root and root bark of A. indica, could be utilized as a good source of nutrient supplement, as well as source of useful pharmaceutical products.
Variation among pineapple half-sibs and selecting genitors based on potential genetic divergence

Knowledge about variation and relative importance of agronomic traits for genetic divergence studies can reveal useful information to guide the breeding programs. The objective of this study was to evaluate the phenotypic variation, and select of pineapple half-sib seedlings based on genetic divergence of fruit and plant traits. 'Pérola' cultivar (female genitor) received a pollen mix as from cultivars 'MD-2', 'BRS Imperial' and 'BRS Vitória' (male genitors). Four hundred twenty-nine F1 individuals propagated from seeds were evaluated under field conditions. Descriptive statistics, Singh's (1981) relative contribution, and Tocher's cluster optimization methods based on the distances matrix were estimated. Coefficients of variation ranged from 9.89 % to 63.79 %. Regarding total variance, fruit traits grouped 52.69%, while plant traits accumulated 47.30%. These results demonstrated that evaluated traits contribute for half-sib progeny relative discrimination and that none of them should be discarded for studies of diversity. Among the 12 heterotic clusters formed, group VII, IX and VIII are recommended to compose hybridization blocks and evaluation cycles of phenotypic stability for use per se. These groups have a broad heterotic potential, and desirable agronomic traits, mainly regarding to high means for fruit mass without crown (FMWC) upper than 4,000g and soluble solids content (SSC) around 20-21°Brix, which can be used by the IPA’s pineapple breeding program.
Resection or Preservation? A Tough Surgical Decision for Chinese Breast Cancer Patients Who Are in Line with Breast Conserving

Purpose Breast cancer patients who are in line with breast conserving are faced more challenges in making surgery decision, because breast conservation and mastectomy have equivalent oncologic outcomes. The purpose of this study is to analyze the surgical decision-making process for breast cancer patients and further explore the reasons why do Chinese women who are in line with breast conserving are more likely to choose mastectomy. Methods A qualitative study was conducted. With the sample saturation principle, data collected by semi-structured interviews with 14 breast cancer patients who are in line with breast conserving. Colaizzi’s method of phenomenology was used for data analysis. Results Three major themes emerged from the data. The themes were the following: (1) lack of significant decision-making support (stereotyping of breast cancer surgery, Inferior quality of interaction with health professions, and without the help of decision aids); (2) can’t mull under the strike (immediacy of the decision, breasts are out of deliberating, and escape); and (3) edified by the Chinese culture (deep family values, hiding concerns about femininity, and conservative character). Conclusions Our findings explore the reasons why more Chinese breast cancer patients with breast conserving conditions choose mastectomy, and help patients to choose knowledge-based treatment options which are concordant with their needs, values, and preferences.
Retos en construcción de traductores automáticos para lenguas indígenas de México

La traducción automática es una herramienta que aún con sus limitaciones permite el acceso a ideas e información entre lenguas. Su adopción para las lenguas indígenas de México podría revalorizarlas ante los hablantes que se enfrentan a la situación de qué sistemas digitales no las usan en sus interfaces. En este trabajo presentamos resultados de los primeros traductores de cinco lenguas indígenas: mexicanero, náhuatl, purépecha, wixarika y yorem nokki, con el español; pero más importante presentamos una reflexión sobre las lecciones aprendidas durante este esfuerzos y los retos para poder hacer sistemas de traducción automática funcionales para las lenguas indígenas de México.
A literature review of causes and management of pain related to endodontic procedure

Pain if found to be the prime most factor for most of the patients to visit the dental clinic. Pain can be associated to different reasons, might be due to periodontal reason, due to local infection, due to any oral surgical trauma, due to any peri apical infection, due to impingement of the prostheses to the soft tissue. But most often patient visit to the dental clinic with the pain associated with endodontic reason. So one should have an adequate knowledge to differentiate between the main cause of the endodontic pain and to diagnose the same with a proper treatment plan.
Does the Dark Side of Personality Traits Explain Compulsive Smartphone Use of Higher Education Students? The Interaction Effect of Dark Side of Personality with Desirability and Feasibility of Smartphone Use

Research on compulsive use of smartphones amongst students largely remains unexplored. The study seeks to investigate the feasibility and desirability motives—instant gratification, mood regulations, convenience, flow and personality—to understand the compulsive use of smartphones. The results of the useful data of 200 respondents following purposive sampling design, provided evidence of instant gratification, mood regulation and convenience motives, which significantly explain flow and compulsive smartphone use. Personality of users also appeared as a significant moderator between flow and compulsive smartphone use. The findings of the study reveal that the personality of smartphone users enhances the propensity to build compulsive smartphone use. Additionally, the findings reveal the double-edged sword impact of flow in forming compulsive smartphone use and allowing smartphone brands to design phones that help phone users to develop self-control over their behaviours related to using smartphones.
Development of 45S5/PEEK Bioactive Coatings by Cold Gas Spray for Orthopedic Implants

Cold Gas Spray (CGS) technology has allowed the development of biofunctional composite coatings composed of 45S5 and Polyetheretherketone (PEEK). The combination of a bioactive glass material embedded in a biocompatible polymeric matrix becomes this new composite in an interesting material for orthopedic applications since meet the biomechanical and biological requirements of an artificial implant. In the present study, blends of bioactive glass 45S5 and PEEK powder with different granulometry and 45S5/PEEK ratio have been prepared. These mixtures of powders have been deposited onto PEEK substrates by CGS with the goal of incorporating a bioactive additive to the biocompatible polymer, which can improve the bone-implant interaction of PEEK. The deposition efficiency (DE) and thickness of the coatings have been evaluated and from the results obtained, it was possible to conclude that DE and coating thickness are significantly affected by the granulometry and by the 45S5/PEEK ratio of the blends. By Scanning Electron Microscopy (SEM) inspection, it was observed that the use of blends with high 45S5/PEEK ratio led to the deposition of coatings with high content of 45S5 particles embedded in the polymeric matrix. Finally, the friction behavior of the coatings was analyzed performing ball-on-disk tests and these experiments showed that the presence of glass particles has a beneficial role in the wear resistance of the coatings.
STAKEHOLDERS` PERCEPTION ON USEFULNESS OF PUBLISHED CORPORATE ANNUAL REPORTS

Corporate financial reporting acts as an information system between the management and stakeholders. The management communicates the relevant quantitative and qualitative information to the various stakeholders for decision making. Enhanced disclosure of the relevant information brings about the transparency which increases the credibility of the company and boosts investor confidence thereby promoting an investor friendly market. Although information about the company affairs can be communicated through other media like financial press release, interim reports newspapers, business and industry journals, Published Corporate Annual Report is regarded as the most important source of information about the company’s affairs. The present study examines the stakeholders’ perception on the usefulness of published corporate annual reports. Kruskal Wallis test has been applied to investigate whether the type of stakeholder affects the stakeholders’ perception on usefulness of published corporate annual reports.
Study the analgesic effect of diclofenac and silymarin coadministration in chicks

Article history: Received May 07, 2020 Accepted May 22, 2020 Available online December 7, 2021 The study aimed to investigate the analgesic as well as anti-inflammatory effects of diclofenac and silymarin in chicks. The up and down procedure was used to assess the effective median analgesic dosages (ED50s) of diclofenac and silymarin administered intraperitoneally either alone or at the same time in chicks. Also, Analgesic and antiinflammatory effects were measured by using the formalin test. Isobolographically, ED50s of drugs were assessed for the manner of interaction between both. Formalin testing also supervised analgesic and anti-inflammatory coadministration impact of diclofenac and silymarin at doses 5 and 40 mg/kg and 2.5 and 20 mg/kg respectively. Analgesic ED50s for diclofenac and silymarin in chicks were 9.3 and 76.6 mg/kg separately. Concomitant administration of drugs at a fixed ratio 0.5:0.5 and 0.25:0.25 of their individual ED50 values reduced their ED50s to 2.3:18.6 mg/kg and 2.2:16.5 mg/kg separately. ED50s isobolographic analysis showed synergistic analgesic effects of both drugs. Additionally, coadministration of both drugs had effective analgesic and anti-inflammatory effect, as seen by formalin test, led to a significant rise in latency to lift right foot beside a significant decline in foot lifting frequency when compared with control value, the antiinflammatory reaction was demonstrated by a significant decrease in foot thickness compared to control value. In conclusion, the data indicate that diclofenac and silymarin coadministration controls acute pain synergistically, and suppress inflammatory reaction.
SYNTHESIS OF FUNCTIONAL NANOPARTICLES FOR APPLICATION IN INKJET PRINTING

Ag nanoflakes were synthesized by chemical reduction method using cetyltrimethylammonium bromide (CTAB) as a surfactant. The results of transmission electron microscope (TEM) analysis, ultraviolet-visible spectroscopic (UV-Vis) analysis, X-ray diffraction (XRD) analysis showed that the obtained Ag nanoflakes had size of ~50 – 60 nm, thickness of 16 nm, with flake shape reached 96 %. The particles crystallized in cubic structure of Ag. The Ag nanoflakes synthesized with pH = 4 were dispersed stably after 60 days from synthesis. The properties of the obtained Ag nanoflakes were suitable for using them as conductive particles in fabrication of functional inks for electrohydrodynamic printing technique.
Effect of synthetic route in particle size distribution of zinc oxide, silver and carbon nanoparticles and its role in controlling phytopathogenic fungus Alternaria solani

Abstract There are plethoras of studies on antifungal effect of nanomaterials. But the effect of synthetic route on physico-chemical characteristics of nanoparticles and its corresponding effect on antifungal effect are not properly investigated. Though green synthesis is considered to be more eco-friendly and economical, mostly resultant nanomaterials have much broader size range in comparison with those prepared chemically. In this study three nanoparticles – zinc oxide, silver and carbon were prepared both by chemical and green routes and their efficacy was evaluated in controlling Alternaria solani, a phytopathogenic fungus. The average particle size of both zinc oxide and silver nanoparticles was smaller in case of chemical synthesis and these particles were much more potent antifungal agent than those particles that were synthesised by green route. In our study, there was no effect of synthetic route in size and shape of carbon nanoparticles and these particles were mostly not effective against A. solani. Supplemental data for this article is available online at https://doi.org/10.1080/03235408.2021. 1936868 .
Ideology and Institutional Change: The Case of the English National Planning Policy Framework

ABSTRACT This paper deploys a discursive institutionalist framework to explore how various categories of ideas – from ideology, to programme, to policy – interact to shape the planning policymaking process. Using the emergence of the 2012 National Planning Policy Framework in England as a case study, the role of the political ideology of the leadership of a political party (as distinct from, but related to, the broader category of ‘neoliberalism’) in shaping and legitimising planning reform is analysed. It is shown that it is not only the political ideological legacy of a political party and how it melds with the prevailing paradigmatic orthodoxy (such as neoliberalism) that matters in framing planning reform, but that the way in which ideas are communicated and consulted on in the policymaking process is also significant.
