Aim: Dental hypersensitivity is commonly complained by the subjects in the dental office or hospitals. Our chief aim was to compare two commercially available toothpastes containing Calcium sodium phosphosilicate and 5% potassium nitrate for the treatment of dentinal hypersensitivity. Materials and methods: Sixty subjects with the chief complaint of dentinal hypersensitivity were selected and randomly divided into two groups. Assesment of hypersensitivity was done using visual analog scale (VAS) scores by applying water and air stimuli at baseline, 3 weeks after usage of the respective provided toothpaste, and 3 weeks after discontinuation i.e., 6 months of the respective toothpaste. Results: Both the groups showed reduction in hypersensitivity scores at 3 weeks and 6 weeks for air and water stimulus. The group provided with toothpaste containing potassium nitrate, however, showed significantly better reduction in hypersensitivity compared to the group provided with toothpaste containing calcium sodium phosphosilicate.
The Paradox of Self-Blame
Authors: Todd Patrick , Rabern Brian 
Published: May 2022

AbstractIt is widely accepted that there is what has been called a non-hypocrisy norm on the appropriateness of moral blame; roughly, one has standing to blame only if one is not guilty of the very offence one seeks to criticize. Our acceptance of this norm is embodied in the common retort to criticism, “Who are you to blame me?” But there is a paradox lurking behind this commonplace norm. If it is always inappropriate for x to blame y for a wrong that x has committed, then all cases in which x blames x (i.e., cases of self-blame) are rendered inappropriate. But it seems to be ethical common-sense that we are often, sadly, in position (indeed, excellent, privileged position) to blame ourselves for our own moral failings. And thus, we have a paradox: a conflict between the inappropriateness of hypocritical blame, and the appropriateness of self-blame. We consider several ways of resolving the paradox and contend none is as defensible as a position that simply accepts it: we should never blame ourselves. In defending this starting position, we defend a crucial distinction between self-blame and guilt.

Authors: Bhattarai Lata , Sharma Mamata 
Published: May 2022

Background: Attention deficit hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children. ADHD knowledge among teachers helps managing such children. This study aimed to assess the knowledge regarding ADHD of children among school teachers at Lalitpur, Nepal.
Methods: A descriptive cross-sectional study was conducted among 124 primary school teachers in 19 government schools of Lalitpur Metropolitan City. A standard tool “Knowl­edge of Attention Deficit Disorders Scale (KADDS)” was used, which is valid and reliable tool designed by Sciutto and colleagues. Data were collected from 2017/06/20 to 2017/07/20. Data were analyzed using descriptive (frequency, percentage, mean and standard deviation) and inferential statistics (chi square test) for frequency distribution and association between levels of knowledge regarding ADHD with selected variables.
Results: Eighty-five (68.5%) female and 39 (31.5%) male teachers with the mean age 41.85 ± 8.80 years (range 18 to 58 years) were enrolled. Majority teachers were married (94.4%) and from urban area (75%) with bachelor’s degree (37.9%) as their educational qualification and 11 to 20 years of teaching experiences (42.74%). The significant influencing variables were educational qualification (p = 0.009), type of service (p = 0.018), teaching experiences (p = 0.002), in-service education on ADHD (p = 0.004) and experience with ADHD students (p = 0.001). The study showed that 94 (75.8%) teachers had poor knowledge.
Conclusions: It was concluded that three fourth of the teachers had poor knowledge about ADHD. Teachers knowledge will help to identify, refer and help in management of children with ADHD.

Published: May 2022

En esta ponencia se exponen los resultados parciales de dos proyectos deinvestigación que analizan la formación de los alumnos universitariosavanzados de turismo, de los graduados y su inserción laboral comopercepción de desempeño en el mercado de trabajo; en un ámbito donde laActividad del turismo es un pilar de la economía. Se ha realizada unainvestigación cuali - cuantitativa mediante entrevistas a consultoras deRecursos Humanos y encuestas a los alumnos avanzados de las carreras deLicenciatura y Guía en Turismo de las dos Universidades que dictancarreras de Turismo en Misiones, y a egresados de la Carrera de Licenciatura y Guía de Turismo. Se observa que si bien existe un importante crecimiento del sector turístico en la provincia de Misiones y Argentina, no necesariamente genera desarrollo para el sector estudiado, porque los salarios del sector son insuficientes y los profesionales deben tener más de un empleo o por inestabilidad laboral y dificultades de ascenso. Finalmente, se pueden destacar las posturas diferentes acerca del que es “ser profesional en turismo”, y en qué estadio se encuentra la profesionalización en Misiones. Entre los aspectos a mejorar para lograr una mayor profesionalización en el turismo en Misiones se destacan por un lado la necesidad de ordenar más la actividad turística (que al ser reciente está desordenada y en parte des regulada, siendo una propuesta que supera el ámbito laboral y educativo), profundizar en la calidad y en la competitividad de empresas, destinos y trabajadores, especializar al recurso humano y formarlo más en cuestiones financieras y contables, trabajar más en la actitud y los valores de responsabilidad, ética y de formación integral. Palabras Clave: formación universitaria, inserción laboral y de laprofesionalización.

Introduction: In general, the creation system in Brazil has been characterized as an activity of great importance in the socio-economic market, as it generates employment and income opportunities.
Aims: This work aims to carry out a brief bibliographical review regarding the use of sustainability indicators within the creation systems.
Literature Review: The notion of sustainability is still a recent term and is under construction. Among the countless concepts of sustainability found in specialized literature, sustainability means the "possibility of continuously obtaining equal or superior conditions of life for a group of people and their successors in a given ecosystem. On the other hand, the concept of indicators, as well as for the concept of sustainability does not have a universal definition. Sustainability indicator “is an instrument that allows, based on its interpretation, to define the condition of a system as sustainable or not.” In other words, sustainability indicators can be understood as parameters, in which the assessment shows whether the limit, established according to the values ​​and objectives that govern a given reality, was exceeded or respected.

Background: The increase in prevalence of antimicrobial-resistant bacteria (ARB) is currently a serious threat, thus there is a need for new classes antimicrobial compounds to combat infections caused by these ARB. The growth inhibition ability of derivatives of the components of nucleic acids has been well-characterized but not for its antimicrobial characteristics.
Aims: To evaluate in vitro antimicrobial activity profile of modified pyrimidine nucleosides derivatives.
Methodology: Modified nucleosides arabinofuranosylcytosine (cytarabine, ara-C), [1-(2',3',5'-tri-O-acetyl-β-D-ribofuranosyl)-4-(1,2,4-triazol-1-yl)]uracil (TTU), and nucleotides cytarabine-5′-monophosphate (ara-CMP), and O2,2′-cyclocytidine-5′-monophosphate (cyclocytidine monophosphate, cyclo-CMP) were synthetized and subsequentially checked for antibacterial activity. Bacterial cells characteristics were assessed by antiproliferative and the production of intracellular reactive oxygen species (ROS) assays.
Results: It was found that modified nucleosides ara-C, and TTU, and nucleotides ara-CMP, and cyclo-CMP were able to inhibit Escherichia coli, Sarcina lutea, Bacillus cereus, and Proteus mirabilis strains in a time and dose dependent manner via killing kinetics assay. Gram-negative (E. coli and P. mirabilis) bacteria stains were more sensitive to the exposure of TTU and cyclo-CMP and less sensitive to the exposure of ara-C and ara-CMP compared to gram-positive ones. The most effective cells growth inhibitor for gram-positive strains (S. lutea, B. cereus) was ara-CMP with ED50 = 5.2•10-5 M and 3.1•10-4 M, respectively. Sarcina lutea appeared to be the most sensitive bacteria strain to the exposure of all studied compounds. It was demonstrated that studied modified pyrimidine nucleosides derivatives enhanced the production of intracellular ROS over time (validated via DCFA-DA probe assay).
Conclusion: This study has revealed the mechanism of action of cytarabine, cyclocytidine monophosphate, and TTU as an antimicrobial agent for the first time, and has shown that these pyrimidine derivatives enhanced might be able to combat infections caused by Escherichia coli, Sarcina lutea, Bacillus cereus, and Proteus mirabilis in the future.

AbstractSurface oxygen vacancies have been widely discussed to be crucial for tailoring the activity of various chemical reactions from CO, NO, to water oxidation by using oxide‐supported catalysts. However, the real role and potential function of surface oxygen vacancies in the reaction remains unclear because of their very short lifetime. Here, it is reported that surface oxygen vacancies can be well confined electrostatically for a polarization screening near the perimeter interface between Pt {111} nanocrystals and the negative polar surface (001) of ferroelectric PbTiO3. Strikingly, such a catalyst demonstrates a tunable catalytic CO oxidation kinetics from 200 °C to near room temperature by increasing the O2 gas pressure, accompanied by the conversion curve from a hysteresis‐free loop to one with hysteresis. The combination of reaction kinetics, electronic energy loss spectroscopy (EELS) analysis, and density functional theory (DFT) calculations, indicates that the oxygen vacancies stabilized by the negative polar surface are the active sites for O2 adsorption as a rate‐determining step, and then dissociated O moves to the surface of the Pt nanocrystals for oxidizing adsorbed CO. The results open a new pathway for tunable catalytic activity of CO oxidation.
Triggering Lattice Oxygen Activation of Single‐Atomic Mo Sites Anchored on Ni–Fe Oxyhydroxides Nanoarrays for Electrochemical Water Oxidation

Published: May 2022

AbstractTuning the reactivity of lattice oxygen is of significance for lowering the energy barriers and accelerating the oxygen evolution reaction (OER). Herein, single‐atomic Mo sites are anchored on Ni–Fe oxyhydroxide nanoarrays by a facile metal–organic‐framework‐derived strategy, exhibiting superior performance toward the OER in alkaline media. In situ electrochemical spectroscopy and isotope‐labeling experiments reveal the involvement of lattice oxygen during OER cycles. Combining theoretical and experimental investigations of the electronic configuration, it is comprehensively confirmed that the incorporation of single‐atomic Mo sites enables higher oxidation state of the metal and strengthened metal–oxygen hybridization, as well as the formation of oxidized ligand holes above the Fermi level. In a word, the considerable acceleration of water oxidation is achieved via enhancing the reactivity of lattice oxygen and triggering the lattice oxygen activation. This work may provide new insights for designing ideal electrocatalysts via tuning the chemical state and activating the anions ligands.
An Open‐Environment Tactile Sensing System: Toward Simple and Efficient Material Identification
Authors: Wei Xuelian , Wang Baocheng , Wu Zhiyi , Wang Zhong Lin 
Published: May 2022

AbstractRobotic perception can have simple and effective sensing functions that are unreachable for humans using only the isolated tactile perception method, with the assistance of a triboelectric nanogenerator (TENG). However, the reliability of triboelectric sensors remains a major challenge due to the inherent environmental limitations. Here, an intelligent tactile sensing system that combines a TENG and deep‐learning technology is proposed. Using a triboelectric triple tactile sensor array, typical characteristics of each testing material can be maintained stably even under different contact conditions (touch conditions and external environmental conditions) by extracting features from three independent electrical signals as well as the normalized output signals. Furthermore, a convolutional neural network model is integrated, and a high accuracy of 96.62% is achieved in a material identification task. The tactile sensing system is exhibited to an open environment for material identification and the real‐time demonstration. Compared to the complex process that humans must integrate multiple sensing (touching and viewing) to accomplish tactile perception, the proposed sensing system shows a huge advantage in cognitive learning for the visually impaired, biomimetic prosthetics, and virtual spaces construction.
Bias‐Triggered Conductivity Switching and High Effective Rectification in Metallocene‐Based Molecular Junctions
Authors: Asyuda Andika , Das Saunak , Lang Heinrich , Zojer Egbert , Zharnikov Michael 
Published: May 2022

AbstractMolecular diodes usually exhibit fixed current values at a specific bias and achieve sizable rectification ratio (RR) at voltages of ≈1.0 V. Here, a series of custom‐designed molecular films of ferrocenyl/ruthenocenyl‐substituted biphenylthiolates and fluorenethiolates on Au (111) is presented, which exhibit a distinctly different behavior. When embedded into two‐terminal junctions, they show two different conduction states, with a high conductivity state at a negative bias and a low conductivity state upon applying a sufficiently high positive bias. Comparing the current values for these two states, an effective RR of more than 1000 is obtained, a value comparable to the best performing molecular diodes but attained already at particularly low voltages. Significantly, the switching between the conduction states is reversible and the initial, high conductivity state can be recovered by the application of a negative bias. The proposed explanation for these observations is the bias‐induced switching of the junction to a metastable state comprising oxidized ferrocenyl/ruthenocenyl entities, which are characterized by less delocalized frontier orbitals and cause the formation of a significant potential barrier within the junction. It is hypothesized that this state can be stabilized by structural changes in the monolayers, affecting also their coupling to the top electrode.
Bubble size distribution in a bubble column with vertical tube internals: Experiments and CFD‐PBM simulations
Authors: Guan Xiaoping , Yang Ning 
Published: May 2022

AbstractKnowledge of bubble size distribution (BSD) is critical for controlling mass transfer and reaction in bubble column reactors. Installation of internals further complicates this issue. The effects of internals on BSD were systematically investigated through experiments and computational fluid dynamics‐population balance model simulations. The experiments show a bimodal distribution of the volume‐based BSD except at low superficial gas velocity of 0.01 m/s. Addition of 20% internals increases the small‐bubbles fraction, making the first BSD peak more evident. Correspondingly, the simulation reveals a prominent decrease of turbulent dissipation rate and turbulent kinetic energy. Moreover, while the unresolved turbulent kinetic energy dominates in the empty columns, the resolved portion becomes the major component in the presence of internals. This suggests that internals may redistribute turbulent kinetic energy in each scale, which provides more insights into the complex flow characteristics in the presence of internals and process intensification.
