Authors: Hu Ping , Mao Jiajia , Nie Hongkun , Wang Ruihua , Zhang Baitao , Li Tao , He Jingliang , Yang Kejian
Published: July 2021

A saturable absorber (SA) based on niobium diselenide (NbSe2), which is a layered transition metal dichalcogenide (TMD) in the VB group, is fabricated by the optically driven deposition method, and the related nonlinear optical properties are characterized. The modulation depth, saturable intensity, and nonsaturable loss of the as-prepared NbSe2 nanosheet-based SA are measured to be 16.2%, 0.76 MW/cm2, and 14%, respectively. By using the as-fabricated NbSe2 SA, a highly stable, passively Q-switched, erbium-doped, all-fiber laser is realized. The obtained shortest pulse width is 1.49 μs, with a pulse energy of 48.33 nJ at a center wavelength of 1560.38 nm. As far as we know, this is the shortest pulse duration ever obtained by an NbSe2 SA in a Q-switched fiber laser.

Olive vegetation water (OVW) is a by-product with a noticeable environmental impact; however, its polyphenols may be reused food and feed manufacture as high-value ingredients with antioxidant/antimicrobial activities. The effect of dietary supplementation with OVW polyphenols on the gut microbiota, carcass and breast quality, shelf life, and lipid oxidation in broiler chickens has been studied. Chicks were fed diets supplemented with crude phenolic concentrate (CPC) obtained from OVW (220 and 440 mg/kg phenols equivalent) until reaching commercial size. Cloacal microbial community (rRNA16S sequencing) was monitored during the growth period. Breasts were submitted to culture-dependent and -independent microbiological analyses during their shelf-life. Composition, fatty acid concentration, and lipid oxidation of raw and cooked thawed breasts were measured. Growth performance and gut microbiota were only slightly affected by the dietary treatments, while animal age influenced the cloacal microbiota. The supplementation was found to reduce the shelf life of breasts due to the growth of spoilers. Chemical composition and lipid oxidation were not affected. The hydroxytyrosol (HT) concentration varied from 178.6 to 292.4 ug/kg in breast muscle at the beginning of the shelf-life period. The identification of HT in meat demonstrates that the absorption and metabolism of these compounds was occurring efficiently in the chickens.
Large-Scale Reassessment of In-Vineyard Smoke-Taint Grapevine Protection Strategies and the Development of Predictive Off-Vine Models

Published: July 2021

Smoke taint in wine is thought to be caused by smoke-derived volatile phenols (VPs) that are absorbed into grape tissues, trapped as conjugates that are imperceptible by smell, and subsequently released into wines as their free odor-active forms via metabolism by yeasts during fermentation. Blocking VP uptake into grapes would, therefore, be an effective way for vineyards to protect ripening grape crops exposed to smoke. Here, we re-evaluated a biofilm that had previously shown promise in pilot studies in reducing levels of smoke-derived VPs. A suite of nine free and acid-labile VPs were quantitated in Pinot Noir grapes that had been exposed to smoke after being coated with the biofilm one, seven or 14 days earlier. In contrast with earlier studies, our results demonstrated that in all cases, the biofilm treatments led to increased concentrations of both free and total VPs in smoke-exposed grapes, with earlier applications elevating concentrations of some VPs more than the later time points. Tracking VP concentrations through the grape ripening process demonstrated that some (phenol, p/m-cresol, and guaiacol) were not entirely sequestered in grapes as acid-labile conjugates, suggesting the presence of VP storage forms beyond simple glycosides. Free VPs in grapes, though a minor portion of the total, most clearly correlated with concentrations present in the resulting wines. Finally, red table grapes, available year round, were observed to replicate the effects of the biofilm treatments and were capable of transforming most VPs into acid-labile conjugates in under 24 h, indicating that they might be an effective model for rapidly assessing smoke-taint prophylactic products in the laboratory.
Anomalous Terminal Shear Viscosity Behavior of Polycarbonate Nanocomposites Containing Grafted Nanosilica Particles
Authors: Ramakrishnan Vaidyanath , Goossens Johannes G. P. , Hoeks Theodorus L. , Peters Gerrit W. M.
Published: July 2021

Viscosity controls an important issue in polymer processing. This paper reports on the terminal viscosity behavior of a polymer melt containing grafted nanosilica particles. The melt viscosity behavior of the nanocomposites was found to depend on the interaction between the polymer matrix and the nanoparticle surface. In the case of polycarbonate (PC) nanocomposites, the viscosity decreases by approximately 25% at concentrations below 0.7 vol% of nanosilica, followed by an increase at higher concentrations. Chemical analysis shows that the decrease in viscosity can be attributed to in situ grafting of PC on the nanosilica surface, leading to a lower entanglement density around the nanoparticle. The thickness of the graft layer was found to be of the order of the tube diameter, with the disentangled zone being approximately equal to the radius of gyration (Rg) polymer chain. Furthermore, it is shown that the grafting has an effect on the motion of the PC chains at all timescales. Finally, the viscosity behavior in the PC nanocomposites was found to be independent of the molar mass of PC. The PC data are compared with polystyrene nanocomposites, for which the interaction between the polymer and nanoparticles is absent. The results outlined in this paper can be utilized for applications with low shear processing conditions, e.g., rotomolding, 3D printing, and multilayer co-extrusion.

Published: July 2021

Integrative medicine comprising a tumor-associated antigen vaccine and chemotherapeutic regimens has provided new insights into cancer therapy. In this study, the AB-type diblock copolymers poly(ethylene glycol)–polylactide (PEG–PLA) were subjected to the dispersion of poorly water-soluble molecules in aqueous solutions. The physicochemical behavior of the chemotherapeutic agent DBPR114 in the PEG–PLA-polymeric aqueous solution was investigated by dynamic light scattering (DLS) technology. In vitro cell culture indicated that replacing the organic solvent DMSO with PEG–PLA polymeric micelles could maintain the anti-proliferative effect of DBPR114 on leukemia cell lines. A murine tumor-associated antigen vaccine model was established in tumor-bearing mice to determine the effectiveness of these formulas in inducing tumor regression. The results demonstrated that the therapeutic treatments effectively reinforced each other via co-delivery of antitumor drug/antigen agents to synergistically integrate the efficacy of cancer therapy. Our findings support the potential use of polymeric micellar systems for aqueous solubilization and expansion of antitumor activity intrinsic to DBPR114 and tumor-associated antigen therapy.
Effect of the Processing on the Resistance–Strain Response of Multiwalled Carbon Nanotube/Natural Rubber Composites for Use in Large Deformation Sensors

Published: July 2021

The dispersion, electrical conductivities, mechanical properties and resistance–strain response behaviors of multiwalled carbon nanotube (MWCNT)/natural rubber (NR) composites synthesized by the different processing conditions are systematically investigated at both macro- and micro-perspectives. Compared with the solution and flocculation methods, the two roll method produced the best MWCNTs distribution since the materials are mixed by strong shear stress between the two rolls. An excellent segregated conductive network is formed and that a low percolation threshold is obtained (~1 wt.%) by the two roll method. Different from the higher increases in conductivity for the composites obtained by the solution and flocculation methods when the MWCNT content is higher than 3 wt.%, the composite prepared by the two roll method displays obvious improvements in its mechanical properties. In addition, the two roll method promotes good stability, repeatability, and durability along with an ultrahigh sensitivity (GFmax = 974.2) and a large strain range (ε = 109%). The ‘shoulder peak’ phenomenon has not been observed in the composite prepared by the two roll method, confirming its potential for application as a large deformation monitoring sensor. Moreover, a mathematical model is proposed to explain the resistance–strain sensing mechanism.
Enhancing the Facilitation of Interprofessional Education Programs: An Institutional Ethnography
Authors: Ezzeddine Nadine , Price Sheri Lynn
Published: July 2021

Interprofessional collaboration (IPC) among health care professionals has been identified as essential to enhance patient care. Interprofessional education (IPE) is a key strategy towards promoting IPC. Several factors including the nature of facilitation shape the IPE experience and outcomes for students. Stereotypes held by students have been recognized as a challenge for IPE and IPC. This study aimed to explore institutional rules and regulations that shape facilitators’ work in IPE interactions problematized by students’ stereotypes at a university in Atlantic Canada. Employing institutional ethnography as a method of investigation, data were collected through observations, interviews, focus groups, and written texts (such as course syllabi). Participants included three facilitators, two undergraduate nursing students, and two IPE committee members of an IPE program. Findings revealed four work processes conducted by facilitators in local IPE settings related to students’ stereotypes. These processes were shaped by translocal discourse and included the work used to form teams, facilitate student introductions to team members, facilitate team dynamics, and provide course content and context. Study results included the identification of several strategies to address student stereotypes and enhance collaboration, including directions for future curriculum decisions and the pedagogical organization of IPE.

Published: July 2021

Colorado potato beetle (CPB) is an economic pest of potato that has developed resistance to all classes of chemical insecticides, thus requiring alternative control measures. As a potential solution, entomopathogenic nematodes (EPNs) have proven effective in suppressing this pest, but their efficacy against overwintering generations of CPB in Croatia has not been sufficiently researched. The aim of this two-year (2018–2019) field study was to determine the efficacy of Steinernema feltiae and Steinernema carpocapsae applied to overwintering CPB adults. EPNs were applied at three doses (7.5 mil./10 m2, 5.0 mil./10 m2 (the recommended dose) and 2.5 mil./10 m2) by watering the soil where the adults were overwintering. The first-year results were satisfactory for both EPNs: the efficacy of S. feltiae ranged from 79.03% to 100.00%, while the efficacy of S. carpocapsae ranged from 77.32% to 96.22%. In the second year, the highest efficacy (69.57%) was obtained using the recommended dose of S. feltiae. Although the results are not consistent across the two years of our study and suggest further research, they indicate that EPNs have great potential in controlling overwintering CPB generations to reduce first generation abundance and damage, and also to prevent the spread of new generations to surrounding potato growing areas.

Published: July 2021

The appearance of pest insects can lead to a loss in yield if farmers do not respond in a timely manner to suppress their spread. Occurrences and numbers of insects can be monitored through insect traps, which include their permanent touring and checking of their condition. Another more efficient way is to set up sensor devices with a camera at the traps that will photograph the traps and forward the images to the Internet, where the pest insect’s appearance will be predicted by image analysis. Weather conditions, temperature and relative humidity are the parameters that affect the appearance of some pests, such as Helicoverpa armigera. This paper presents a model of machine learning that can predict the appearance of insects during a season on a daily basis, taking into account the air temperature and relative humidity. Several machine learning algorithms for classification were applied and their accuracy for the prediction of insect occurrence was presented (up to 76.5%). Since the data used for testing were given in chronological order according to the days when the measurement was performed, the existing model was expanded to take into account the periods of three and five days. The extended method showed better accuracy of prediction and a lower percentage of false detections. In the case of a period of five days, the accuracy of the affected detections was 86.3%, while the percentage of false detections was 11%. The proposed model of machine learning can help farmers to detect the occurrence of pests and save the time and resources needed to check the fields.

Authors: Abdul Rasool Bazigha K. , Mohammed Amira A. , Salem Yasmein Y.
Published: July 2021

Dimenhydrinate is an over-the-counter medication that is used to relieve nausea, vomiting, and vertigo caused by motion sickness. It has a short elimination half-life, possibly due to its first-pass metabolism. The current study aimed to prepare and evaluate new transdermal formulations of dimenhydrinate to prolong the drug’s release and improve its cutaneous permeation. First, the patches were fabricated and evaluated to determine their properties. The results were statistically investigated and considered significant at the p < 0.05 level. Additionally, the quantitative analysis of the drug-release data and kinetic modeling was performed by using the DDSolver software to decide the candidate formula dependably. The effect of the penetration enhancers on the permeability of dimenhydrinate from the selected patch was then studied ex vivo compared to the control sample, and the patch’s safety was evaluated in rabbits, using the skin-irritation test.

A correlação entre a Teoria Vygotskyana e a Teoria da Objetivação no processo de ensino e aprendizagem da Matemática
Authors: Batista Antonia Naiara de Sousa , Oliveira Gisele Pereira , Pereira Ana Carolina Costa
Published: July 2021

A partir de estudos e seminários realizados na disciplina intitulada, Teorias da Educação e Formação de Professores, realizada na Pós-graduação em Educação na Universidade Estadual do Ceará, no semestre 2020.1, tivemos o contato com diferentes estudos realizados por teóricos no âmbito da Educação, como Piaget, Saviani, John Dewey, Paulo Freire, entre outros. No entanto, nesse estudo vamos dar ênfase, ao estudo da Teoria de Vygotsky (TV), principalmente, porque a partir de pesquisas, percebemos que poderia existir uma relação com a Teoria da Objetivação (TO), desenvolvida por Luis Radford, a qual estamos trabalhando no momento. Assim, nos empenhamos nesse estudo, com vista a conhecer as relações existentes entre a TV e a TO como base para o ensino e aprendizagem de Matemática. Esse estudo se caracteriza como qualitativo, envolvendo aspectos exploratórios e descritivos. E por meio desse processo realizado foi possível perceber que ambos consideram elementos como, a linguagem (signos), artefatos, interiorização e semiótica, no processo de ensino e aprendizagem. Todavia, na TV esses termos são levados para uma esfera mais psicológica, enquanto que, na TO, Radford procura vincular esses elementos ao processo de ensino e aprendizagem numa concepção mais pedagógica. Desta forma, esse estudo visa contribuir para as pesquisas que vem sendo realizadas com o intuito de compreender como as teorias estão articuladas no processo de ensino e aprendizagem, principalmente, no campo da Educação Matemática.

Authors: Azarova Natalia
Published: July 2021

The article is devoted to the study of the growing trends in the quality of the environment in the regions, in the pursuit of trends in the development of the "green economy" in the Russian Federation. The author studied the issue of the prospects for solving environmental problems within the framework of state documents developed in the field of developing solutions to environmental problems in the country's economy and the economy of the regions for sustainable development. The way to activate these processes will be environmental innovations. The author put forward a controversial assumption about the possibility of interaction between human capital and environmental innovations in a regional context, highlighted the prerequisites for creating eco-innovations at the regional level, determined the target group (youth) for the prospects of researching environmental-oriented behavior to stimulate the economically innovative sustainable development of the region. Research was carried out in the form of surveys of this target category, priority directions for the application of the development of environmentally friendly activities of youth were identified in the form of participation in public organizations, environmental festivals, the use of mobile applications for environmental public control. Under the influence of these tools, human capital acquires new qualities: the growth of social environmental responsibility and environmental culture in the region. This trend will also be a sign of the emergence of a civil society.
ANALYSIS AND DIRECTIONS FOR IMPROVING THE SYSTEM OF INCENTIVES FOR EMPLOYEES IN THE CIVIL SERVICE
Authors: Ivanova Elena , Kolesnichenko Elena
Published: July 2021

The article examines the actual problem of stimulating the work of civil servants. The authors analyzed the theoretical aspects of motivation and stimulation and concluded that the interpretations of the concepts of motivation and stimulation have significant differences, and the emphasis should be on the combination of material and non-material tools. The analysis of the motivation system for civil servants was carried out on the basis of materials from one of the departments of the regional administration. It was revealed that for certain structural divisions of the civil service, an outflow of personnel is characteristic, and the main reasons are: dissatisfaction with the level of material support; discrepancy between the level of wages and the costs of individual resources for the implementation of labor activities; lack of recognition of their merits. The authors analyzed the content of tangible and intangible instruments in the public administration system and concluded that the main principles of intangible incentives for civil servants should be: justice, equal opportunities, objectivity, consistency, transparency, awareness. Recommendations on the effective use of the system of non-material incentives are offered: ways of non-material incentives for an employee should be tangible; carry out only an objective assessment of the results of activities; the criteria should be made clear, transparent and easily verifiable; the indicators, in accordance with the achievement of which the incentive is carried out, must be achievable; control at all stages of measures for non-material incentives for employees.
