Laves phase crystal analysis (LaCA): Atomistic identification of lattice defects in C14 and C15 topologically close-packed phases
Authors: Xie Zhuocheng , Chauraud Dimitri , Bitzek Erik , Korte-Kerzel Sandra , Guénolé Julien 
Published: May 2021

Abstract
The identification of defects in crystal structures is crucial for the analysis of atomistic simulations. Many methods to characterize defects that are based on the classification of local atomic arrangement are available for simple crystalline structures. However, there is currently no method to identify both, the crystal structures and internal defects of topologically close-packed (TCP) phases such as Laves phases. We propose a new method, Laves phase crystal analysis (LaCA), to characterize the atomic arrangement in Laves crystals by interweaving existing structural analysis algorithms. The new method can identify the polytypes C14 and C15 of Laves phases, typical crystallographic defects in these phases, and common deformation mechanisms such as synchroshear and non-basal dislocations. Defects in the C36 Laves phase are detectable through deviations from the periodic arrangement of the C14 and C15 structures that make up this phase. LaCA is robust and extendable to other TCP phases.

AbstractCsPbBr3 represents a highly attractive material for perovskite light-emitting diodes (PeLEDs) in the green spectral range. However, the lack of deposition tools for reproducible and scalable growth of perovskite films is one of the major obstacles hindering PeLED commercialization. Here, we employ the highly scalable showerhead-assisted chemical vapor deposition (CVD) method to produce uniform pinhole-free CsPbBr3 films for PeLED application. The precursors CsBr and PbBr2 are evaporated under low vacuum in N2 carrier gas. By adjusting the PbBr2 sublimation temperature, process conditions for CsBr-rich, stoichiometric, and PbBr2-rich CsPbBr3 layer growth have been developed. A substrate temperature of 160 °C enables direct growth of these CsPbBr3 films on a polymeric hole transport layer (HTL), finally yielding PeLEDs with a maximum luminance of 125 cd/m2. Although the device efficiency still lags behind solution-processed counterparts, our approach presents the first demonstration of PeLEDs containing CsPbBr3 films processed in a perovskite showerhead-assisted CVD reactor.

Purpose of the Study: The present study is intended to determine the level of modernity and cultural change among university students. In addition, the study is also aimed to calculate the relationship between modernity and cultural change.
Methodology: Sequential mixed-method research approach is deployed in this study. Initially, the researcher used a quantitative research approach and surveyed the students using a cross-sectional survey design. A two-stage probability sampling technique was used, and a total of 420 students were selected using the stratified sampling technique and simple random sampling technique, respectively. Data were analyzed using SPSS 25 version.
Principal Findings: The results indicated that modernity and cultural change is not uniform among the respondents, but they varied as per the socio-demographic characteristics of the respondents. However, it is more visible in the material aspect of life than the non-material aspect of the social life among the students. In addition, results also indicated a positive relationship between modernity and changing culture among students.
Applications of the study: The results and findings of the study draw the attention of policymakers and researchers to take necessary steps to increase the benefits of modernity and cultural change and decrease the negative consequences of modernity and cultural change. Special measures are needed to protect local indigenous culture as well.
Novelty/Originality of this Study: The contribution of this study is a university student and modernity in changing values most prominent tool that makes us able to survive in society is cultural patterns through which we learn all that we need to survive and learn behavior, norms, customs repetition of acceptable action, etc. In the nineteenth century, modernization involves culture, and hence it is clear that modern tends are changing old ties of culture.
Sustainability as a “magic concept”
Authors: Ove Tøllefsen Trond 
Published: May 2021

Sustainability studies have not been able to come up with a consensus conceptualization of “sustainability,” despite many attempts. This article asks what this conceptual confusion means. I do this through a (conceptual history) vertical analysis, and horizontal (discourse) analysis of the current use of the term. It finds that sustainability is a perfect fit for what Hupe and Pollit have called a “magic concept,” in that it is; broad, has a positive normative charge, imply consensus or at least the possibility of overcoming current conflicts, and has global marketability (2011: 643). This has both positive and negative effects: On the one hand, the popularity of the concept of sustainability has enabled an overarching discourse on the responsible use of natural resources. On the other hand, the concept is vulnerable to various strategic misuses, ranging from corporate greenwashing to Luddite passions. Based on a vertical analysis of the history of sustainability, this vagueness is not a coincidence: It was part of a political bargain at its birth, where environmental concerns were grafted onto an older discourse on “development” during the writing of the 1987 Brundtland report. Based on a horizontal analysis, this vagueness is now inherent to the concept and cannot be abandoned without losing the very magic qualities that make sustainability such a rallying point. This finding points to the conclusion that we should be cautious about how sustainability is wielded.

Published: May 2021

ObjectiveThere is a need to support healthcare providers, including physician-mothers at all training levels, related to breastfeeding and expressing breast milk. This study was designed to understand the attitudes and preferences of lactating employees regarding current lactation resources at an academic medical center.MethodsCross-sectional survey. Respondents reported their satisfaction with current lactation resources on scale of 0 [complete dissatisfaction] to 100 [complete satisfaction]. Respondents were asked to identify greatest priorities for improvements to existing lactation spaces.Results304 (34.2%) respondents, of whom 69.3% anticipated using a lactation room in the next 5 years. Satisfaction with the current status of lactation rooms was low (mean score 37.8; SD 25.3). Accessible and proximal lactation spaces were highest priorities. More than 50% of respondents indicated daily use of a “nontraditional” lactation space.ConclusionThis study demonstrates the current state of healthcare providers' lactation-related experiences and highlights priorities for improvement, particularly provision of adequate lactation spaces.

ObjectiveThe objective of this study was to determine if patient satisfaction with teleconsults during the COVID-19 pandemic, both with and without corresponding car-side weight measurements, was different from satisfaction with in-person visits prior to the pandemic.MethodsRetrospective descriptive and quantitative analysis was used to examine existing patient satisfaction data collected via email survey from patients who completed at least one in-person visit from March 2019 to February 2020 or at least one teleconsult during April or May 2020.ResultsRespondents reported high levels of satisfaction with teleconsults. Approximately 97% of respondents found teleconsults helpful. Satisfaction with teleconsults during the pandemic, both with and without car-side weight measurements, was similar to satisfaction with in-person visits prior to the pandemic.ConclusionProviding families with teleconsults in conjunction with car-side weight measurements was a successful model for providing lactation services to patients during the COVD-19 pandemic.
The methodologist staff in central libraries of the Russian Federation subjects
Authors: Akilina М. I. 
Published: May 2021

The relevance of the paper topic is due to the need to study the personnel situation in the methodological departments of the central libraries (CB) of the constituent entities of the Russian Federation (RF) in the context of sociocultural transformations and active development of digital technologies. The article objective is to present to the library community the results of the study ”Personnel of methodologists in the central libraries of the constituent entities of the Russian Federation” and subsequent observations of the work of the methodological departments of the regions. It reflects the analysis results of quantitative, job, age composition of the personnel, the educational level of specialists, functional changes in methodological units, the system of advanced training of methodologists, and problems of demanded educational activities. The staffing potential level is quite high in most libraries, because methodologists belong to a promising age group of 55 years with higher education, broad competences, sufficient work experience, regularly updating their knowledge.  At the same time, the author concerns the staff small number and further reduction in its number, the lack of opportunities to fill vacancies, the uneven workload of methodologists by a number of supervised libraries, the lack of standards for staffing special structural units and methodology to determine them, as well as the optimal structure of units. Methodists perform a wide range of responsibilities, being universal specialists, competent on various issues. There is a complication and increase in the requirements for methodical activities. 97,9 % of methodologists have higher education, but their large part does not have a special library education. Methodists receive regular training, but there are virtually no special training courses for methodologists in the training system. The identified problems require solution at coordinating the efforts of the methodological centers and state support.

Authors: Mazov N. A. , Gureyev V. N. , Glinskikh V. N. 
Published: May 2021

Revealing research fronts and detecting research priorities are one of the most significant problems in the science of science and scientific policy due to the crucial importance when planning research. Bibliometric approaches are the main tool when detecting research trends and fronts providing the basis for further expertise of research priority. To date, different approaches have been developed for research trends and fronts detection including analysis of scholarly output, citation analysis, and content analysis. The most spread is citation analysis and its variants, i.e., direct citation analysis, co-citation analysis, and bibliographic coupling. The paper discusses the main features of each method; describes current issues of detecting research fronts and setting of research priorities. The authors conclude that bibliometric approaches for detecting research fronts and research priorities are objective, especially when combining different forms of bibliometric analyses. Bibliometrics seems to be the most promising approach due to its flexibility and capability to be rapidly adapted to a dynamic scientific environment and new publication models.
METHOD OF FORMING AN EFFECTIVE TEAM OF EDUCATIONAL PROFESSIONAL PROJECTS
Authors: Kuzminska Yuliia , Danchenko Elena , Bedrii Dmytro 
Published: May 2021

Project management methodology is widely used in various aspects of educational activities, including in the field of adult education. In-service training projects implemented by higher education institutions in the field of adult education, mainly at public expense, are limited, on the one hand, in terms of implementation, which leads to the impossibility of increasing project implementation time, then in the amount of funding regulated by relevant provisions and resolutions on the organization of professional training (advanced training) of specialists, and on the other hand, the internal regulations and rules of educational institutions on the organization of training and implementation of educational projects in the field of higher education, aimed at working with students. At the same time, the implementation of such projects is subject to increased requirements for their quality. Under such conditions, the implementation of educational projects of professional development is quite difficult. Teams of educational projects of advanced training are formed mainly of persons selected from among the internal employees of the educational institution, who are able to work with an adult audience. To form such teams, it is necessary to take into account the peculiarities of adult learning, the peculiarities of educational projects of professional development and the peculiarities of the teams of such projects. Accordingly, the management of such teams is associated with certain personnel risks that may affect the success of the project. In turn, working with teams whose members have a high creative potential requires effective management methods, one of which is the process of forming a single, coherent team of like-minded people who can effectively achieve the project goal. A method of forming teams of educational projects of advanced training, obtained as a result of cross-evaluation of qualities (creativity) of team members of such projects, taking into account their personnel risks and "degrees of trust", is proposed. It is concluded that this method allows the head of the educational project to increase the efficiency of decision-making on team building or planning of executors for the educational project of professional development, by selecting applicants with the highest "degrees of trust".
Intravenous oxygen insufflation (IOI) changes the IL-1-Ra:IL-1β ratio in autologous conditioned serum
Authors: König Brigitte , Wiechert Dirk 
Published: May 2021

Abstract
Background
Interleukin-1 (IL-1) is still regarded as the main offender that promotes the pro-inflammatory cascade in muscle injuries, tendopathies and especially in osteoarthritis. Thus, if present in high enough concentrations, IL-1receptor antagonist (IL-1Ra) has the potential to inhibit Interleukin-1. In this regard, autologous conditioned serum with an IL-1Ra/IL-1 ratio of at least > 10 might fulfill optimal therapeutic effects. The purpose of this study was to analyze the combination of Regelsberger’s intravenous oxygen insufflation (IOI) with autologous conditioned serum (ACS) on IL-1Ra and IL-1 formation.
Methods
Venous blood from 15 patients which underwent intravenous oxygen insufflation (IOI) for routinely preventive purposes was taken before the first, the 6th, and the 9th session of intravenous oxygen insufflation. IL-1β and IL-1-RA levels were quantified from serum and from autologous conditioned serum (ACS).
Results
Previous intravenous oxygen insufflation treatments significantly reduced IL-1β levels in autologous conditioned serum from mean 67.85pg/ml (before the first treatment) down to mean 4.08pg/ml (before the 9th treatment). Post conditioning levels of IL-1Ra were not changed to any significant degree (before 1st/before6th/ before 9th treatment: 1038.37 ± 140.51 / 900.30 ± 79.24 / 902.84 ± 95.68). Thus, the IL-1Ra:IL-1β ratio was altered on a molecule to molecule basis from a mean of 37.03:1 up to a mean 223.54:1 through the pretreatment.
Conclusion
IOI alters the IL-1Ra:IL-1ß ratio of autologous conditioned serum to a more favorable ratio which might mitigate the inflammatory cascade more efficaciously.
Expression and prognosis analyses of PEA3 subfamily in head and neck squamous cell carcinoma via integrated bioinformatics
Authors: Wei Mei , Wang Wei , Ni Guangjian 
Published: May 2021

Abstract
Backgroud: The PEA3 subfamily belongs to the first category of the ETS family, and it consists of three family members, namely, ETV1, ETV4, and ETV5. These members were implicated in the progression of many cancers. But their prognostic roles in head and neck squamous cell carcinoma (HNSCC) remain to be characterized.Methods: Data from multiple open databases were used to analyze the expression, regulation, mutations, immune infiltration, and functional networks of the PEA3 subfamily in patients with HNSCC. Results: The results demonstrated that these patients showed downregulated ETV1 and upregulated ETV4/5 compared with healthy subjects. Furthermore, high expression of ETV4/5 and low expression of ETV1 were linked to the shortened overall survival in patients with HNSCC. The immune infiltration in B cells stimulated the prognosis, and it may have a prognostic medical significance linked to the PEA3 subfamily in HNSCC. These results showed that data mining efficiently revealed the expression of the PEA3 subfamily in HNSCC, but this study requires further large-scale genomic and basic research.Conclusions: This study provided new insight into the prognostic roles of PEA3 subfamily in HNSCC with potential mechanistic values.

Abstract
Toxic cyanobacteria blooms are a frequent problem in subtropical reservoirs and freshwater systems. The purpose of this study was to investigate the occurrence of potentially toxic cyanobacteria and the environmental conditions associated with the presence of cyanotoxins in a Brazilian subtropical reservoir. Five collections were carried out at seven sampling locations in the reservoir, during the rainy and dry seasons, between the years 2016 and 2017. There was permanent occurrence of Raphidiopsis raciborskii (Woloszynska) Aguilera, Berrendero Gómez, Kastovsky, Echenique & Salerno, ranging between dominant and abundant, with an average biomass of 38.8 ± 29.9 mg L− 1. Also abundant were D. solitarium, D. planctonicum, P. isothrix, and A. gracile. Saxitoxin (STX) was detected in all the collected samples (0.11 ± 0.05 µg L− 1). Microcystin (MC) was also detected, but at lower concentrations (0.01 ± 0.0 µg L− 1). Low availability of NO3− and phosphorus limitation had significant effects on the R. raciborskii biomass and the levels of STX and MC. It was observed that R. raciborskii was sensitive to thermal stratification, at the same time that STX levels were higher. This suggested that STX was produced under conditions that restricted the growth of R. raciborskii. These are important findings, because they add information about the permanent occurrence of STX and R. raciborskii in an aquatic ecosystem limited by phosphorus, vulnerable to climatic variations, and polluted by domestic effluents.
Determination of some heavy metals concentration in species animal meat (sheep, beef, turkey, and ostrich) and carcinogenic health risk assessment in Kurdistan province, western Iran

Published: May 2021

Abstract
Accumulation of heavy metals in food as one of the environmental pollutants due to the development of urban industries and human activities, is one of the threats to public health. The purpose of this study, as the first report in Sanandaj, one of the strategic cities of western Iran, was to investigate the concentration of heavy metals in the meat of different species of sheep, calves, turkeys and ostriches. In a cross-sectional study, the content of selenium, lead, cadmium, arsenic, cobalt, zinc, nickel, copper, and chromium in 170 meat samples prepared from meat distribution centers in Sanandaj was investigated. The content of these elements was measured by the ICP-MS method in the meat of beef, sheep, turkey, and ostrich. Data were analyzed using parametric tests of ANOVA and one-sample t-test, and the correlation coefficient and the relationship among the concentration of metals were also calculated and compared in studied species. The results showed that the mean content of selenium, nickel, cobalt, and chromium in the studied species did not show a significant difference (P > 0.05). However, the mean content of lead, cadmium, arsenic, zinc, and copper showed a significant difference (P < 0.05). A significant negative correlation was also found between cadmium and selenium in turkey meat. With the exception of copper and selenium, the concentrations of other metals were higher than allowed in the meat of the studied species. The Target Risk (TR) of cancer for lead, cadmium, and arsenic in some species studied was higher than allowed (more than 10− 4). Due to the excessive accumulation of carcinogenic heavy metals in sheep, beef, turkey, and ostrich meat, it is necessary to monitor and remove barriers to environmental pollutants.
Music therapy for postoperative pain management after mastectomy in Nigeria: An exploratory qualitative study
Authors: TOLA Yetunde Oluwafunmilayo , Iloba Njokanma G , Chow Ka Ming 
Published: May 2021

Abstract
Purpose

This study aimed to explore the cultural elements of music in relation to pain management among women who have undergone mastectomy.
Method:

An exploratory qualitative study with in-depth interviews. Using the purposive sampling technique, 20 participants were recruited for the study. The interviews were conducted face to face at the surgical out-patient clinic and female surgical ward. Data collection continued until data saturation was reached. The inductive approach was used to analyse the data, and the concepts were organized into themes. The consolidated criteria for reporting qualitative research guidelines (COREQ) were used to report this study.
Results

The participants were between 28 and 83 years old and mostly diagnosed with Stage III breast cancer. Three main themes emerged from the data analysis, including pain experienced after mastectomy, culture and music, and the perception of music for postoperative pain management after mastectomy.
Conclusion

Knowledge and the utilisation of music as a therapy for pain management remains inadequate, but the participants perceived that music could be useful for pain control after mastectomy when the language and religion of the patient and the meaningfulness of the music were considered when introducing and selecting the music. This study will help open and extend the conversation about the utilisation and cultural elements of music that can be used clinically for pain management after mastectomy.
