A Density Functional Theory Study of the Ionic and Electronic Transport Mechanisms in LiFeBO3 Battery Electrodes

Lithium iron borate is an attractive cathode material for Li-ion batteries due to its high specific capacity and low-cost, earth-abundant constituents. However, experiments have observed poor electrochemical performance due to the formation of an intermediate phase, that is, LixFeBO3, which leads to large overvoltages at the beginning of charge. Using a convex-hull analysis, based on Hubbard-corrected density functional theory (DFT+U), we identify this intermediate phase as Li0.5FeBO3. Moreover, we show by means of the nudged elastic band (NEB) method, that the origin of these adverse electrochemical effects can be explained by an intrinsically low Li-ion and electron/hole-polaron mobility in Li0.5FeBO3 due to high activation barriers for both the ionic and electronic transport. These studies include the effects of the experimentally reported commensurate modulation. We have also investigated the Li-ion/hole diffusion through the interface between Li0.5FeBO3 and LiFeBO3, which is found not to result in ad.
Attentiveness Toward Oral Care Needs for Preventing Aspiration Pneumonia: A Comparative Study of Indonesian Care Workers in Japan and Indonesia

Background: Japan has opened its labor market to care workers from Indonesia under the Japan–Indonesia Economic Partnership Agreement (EPA). Many foreign care workers wish to enter Japan to learn skills that they can apply upon returning to work in their home countries. However, little research has examined the types of care skills that could be transferred between countries. In this study, we assessed Indonesian care workers employed at care institutions in Japan and Indonesia to identify discrepancies in their attentiveness toward checking essential points of oral care for older adults. Methods: A checklist comprising 42 items of universal oral care assessment was developed prior to the study. The checklist was distributed via the Internet to 418 Indonesian EPA care workers in Japan, and via a paper survey to 213 Indonesian care workers in Indonesia. The Mann–Whitney U test was used to compare the distribution of scores for each checklist item in each group. Results: The respondents comprised 110 Japan-based EPA care workers (response rate: 26.3%) and 213 Indonesia-based care workers (response rate: 99.1%). Comparing the two groups, Japan-based care workers were significantly more likely to perform environmental observations of their older adult patients (p < 0.001) and to check items on the oral care checklist during feeding (p < 0.01) and post-meal (p < 0.01) periods, while Indonesia-based care workers were more likely to check the overall condition of patients before meals (p < 0.05). Conclusions: Discrepancies between the two groups in checking the essential points of oral care were attributed to differences in laws and regulations governing the care environment. Indonesian care workers employed in Japan have the advantage of learning to provide a more systematic approach to caring for older adults in accordance with Japan’s Long-Term Care Act. This approach could contribute to lowering the risk of aspiration pneumonia in Indonesia. A training program designed for returning migrant workers to transfer newly developed oral care skills will be essential for Indonesia to keep pace with the negative impacts of its aging population.
Adaptive Expertise: A study on the influence of self-determination and transformational leadership

This study aimed to analyze the role of transformational leadership in adaptive expertise and test the mediating role of self-determination in this relationship by satisfying the psychological needs of autonomy, belonging, competence and achievement. The survey was conducted with 383 Brazilian workers. The collected data were analyzed through confirmatory factorial analysis (CFA) and multiple regressions. The results of the analyses made it possible to highlight the positive relationship between transformational leadership, adaptive expertise, and self-determination. Quadruple mediation analysis was performed to evidence the effect of self-determination on the relationship between transformational leadership and adaptive expertise. The results confirm the effect of the transformational leader on competence and the mediating effect of self-determination in this relationship. This research advances in the job demands-resources (JD-R), confirming the importance of the worker's resources and personal resources.
The Effect of Closed Area on Woody Species Regeneration: A Case study in Loma Bosa Woreda, Dawuro zone, Southern Ethiopia

This study examines the effect of closed area on woody species regeneration by comparing the woody species regeneration among closure, open woodland, and degraded land areas in Loma Bosa district, Dawuro zone in southern Ethiopia. Results show that Simpson's Diversity Index was 7.24 for woody species in closed area, 6.01 in open woodland and 3.40 in open degraded land area. Shannon-Weiner Diversity Index(H') was 2.26 for woody species in closed area, 2.38 in open woodland area and 1.56 in open degraded land area. The results of Sorenson's similarity coefficients indicates woody species composition in closed area are highly correlated with open woodland areas. Wood species density were 2,225 ha-1, 1,642 ha-1, and 297 ha-1 for closed area, open woodland area, and open degraded land area, respectively. The results indicate that closed area development enhanced species composition, richness, diversity, woody vegetation regeneration, inverted J shape Diameter at Breast Height (DBH) and height class and higher woody species density and crown cover class percentage compared to open degraded area. Overall results from this study indicated that area closure is important for improvement of woody species regeneration in the study area.
Intraoperative radiotherapy (IORT) induced key molecular pathways in tumor bed of breast cancer patients: a pilot study

Background: Radiotherapy (RT) is recommended to all patients undergoing Breast Conserving Surgery (BCS). Two strategies can be applied to irradiation, External Beam RT (EBRT) in addition, Intraoperative Radiation Therapy (IORT). The aim of this study was to introduce a protein biomarker panel related to molecular function of IORT. Materials and Methods: Six Breast Cancer (BC) patients as a pilot study were treated by 12 Gy (Boost dose) and 21 Gy (Radical dose). Samples tissue included Margin before IORT (MB), and Margin 24 hours After IORT (MA24 h). High-throughput technology such as Isobaric Tag for Relative and Absolute Quantitation (iTRAQ) was performed to study proteomic of IORT-treated tumor bed. Results: We classified 110 differentially expressed proteins (DEPs) as a protein biomarker panel by mapping the annotated coding region sequences to the reference canonical pathways in the KEGG database. Conclusion: The analyses of protein function and signaling pathways of these DEPs reveal a molecular response to the effectiveness of IORT.
Azobenzene Guest Molecules as Light-Switchable CO2 Valves in an Ultrathin UiO-67 Membrane

Metal–organic frameworks (MOFs) with an exceptionally large pore volume and inner surface area are perfect materials for loading with intelligent guest molecules. First, an ultrathin 200 nm high-flux UiO-67 layer deposited on a porous α-Al2O3 support by solvothermal growth has been developed. This neat UiO-67 membrane is then used as a host material for light-responsive guest molecules. Azobenzene (AZB) is loaded in the pores of the UiO-67 membrane. From adsorption measurements, we determined that the pores of UiO-67 are completely filled with AZB and, thereby, steric hindrance inhibits any optical switching. After in situ thermally controlled desorption of AZB from the membrane, AZB can be switched and gas permeation changes are observed, yielding an uncomplicated and effective smart material with remote controllable gas permeation. The switching of AZB in solution and inside the host could be demonstrated by ultraviolet–visible spectroscopy. Tracking the completely reversible control over the permeance .

Bronchodilator reversibility: What are the differences between asthma and chronic obstructive pulmonary disease?

INTRODUCTION: Currently, the bronchodilator reversibility is not recommended to differentiate asthma from chronic obstructive pulmonary disease (COPD); however, physiopathological specificities of each disease contribute to the differences in response to the drug. OBJECTIVES: The objective of this study is to evaluate the differences in bronchodilator response between asthmatic and COPD patients and to determine which of the bronchodilation criteria have the best ability to detect the positive response in these patients. MATERIALS AND METHODS: This was a cross-sectional study. The sample included 104 patients with asthma or COPD who performed lung function tests between January and March 2018. The whole sample was analyzed according to postbronchodilator variation (Δ) of lung function parameters, and the postbronchodilator reversibility was characterized using a multiple bronchodilation criteria. The drug used in reversibility test was salbutamol. RESULTS: In this study, Δ forced-expiratory volume in the 1st s (ΔFEV1) and a Δ Raw was statistically higher in the group with asthma compared with the group with COPD. In the asthma group, the criteria ↓ functional residual capacity (FRC) ≥10%, ↓Raw ≥ 35%, ↑ forced expiratory flow between 25% and 75% of vital capacity (FEF25%–75%) ≥20% and ↑ FEV1 and / or ↑ forced vital capacity ≥12% and 200 mL were those that presented a greater capacity of detecting a positive response to bronchodilator. The criteria ↑ FEF25%–75%≥20% and ↓ FRC ≥ 10% were those that had the greater ability of detecting airway reversibility in COPD group. CONCLUSION: The analysis of postbronchodilator FEV1 and raw modifications as well as the using of a combination of multiple bronchodilation criteria contribute to a deeper characterization of bronchodilator reversibility in asthma and COPD.
Conversion Attribution:What Is Missed by the Advertising Industry?he OPEC Model and Its Consequencesfor Media Mix Modeling

Marketers are currently focused on proper budget allocation to maximize ROI from online advertising. They use conversion attribution models assessing the impact of specifi c media channels (display, search engine ads, social media, etc.). Marketers use the data gathered from paid, owned, and earned media and do not take into consideration customer activities in category media, which are covered by the OPEC (owned, paid, earned, category) media model that the author of this paper proposes. The aim of this article is to provide a comprehensive review of the scientifi c literature related to the topic of conversion attribution for the period of 2010–2019 and to present the theoretical implications of not including the data from category media in marketers’ analyses of conversion attribution. The results of the review and the analysis provide information about the development of the subject, the popularity of particular conversion attribution models, the ideas of how to overcome obstacles that result from data being absent from analyses. Also, a direction for further research on online customer behavior is presented. JEL classifi cation: M31, M37
Bacterial and Fungal Gut Community Dynamics Over the First 5 Years of Life in Predominantly Rural Communities in Ghana

Background Bacterial and fungal microbiotas are increasingly recognized as important in health and disease starting early in life. However, microbiota composition has not yet been investigated in most rural, low-resource settings, and in such settings, bacterial and fungal microbiotas have not been compared. Thus, we applied 16S and ITS2 amplicon sequencing, respectively, to investigate bacterial and fungal fecal microbiotas in rural Ghanaian children cross-sectionally from birth to 5 years of age. Corresponding maternal fecal and breast milk microbiotas were additionally investigated. Results While bacterial communities differed systematically across the age spectrum in composition and diversity, the same was not observed for the fungal microbiota. We also identified a novel and dramatic change in the maternal postpartum microbiota. This change included much higher abundance of Escherichia coli and much lower abundance of Prevotella in the first vs. fourth week postpartum. While infants shared more bacterial taxa with their mother’s stool and breast milk than with those of unrelated mothers, there were far fewer shared fungal taxa. Conclusion Given the known ability of commensal fungi to influence host health, the distinct pattern of their acquisition likely has important health consequences. Similarly, the dynamics of mothers’ bacterial microbiotas around the time of birth may have important consequences for their children’s health. Both topics require further study.
Studies On Release Of Rifampicin From Sintered Matrix Tablets

The new methods for making polymeric systems for the controlled release of rifampicin drug is described. This method is very simple, it consists of mixing drug and polymer powder (ethylene-vinyl acetate copolymer) and compressed at room temperature. The compressed fluffy matrices were kept at 60Â°, 70Â° and 80Â° for 1Â½, 3 and 4Â½ h for sintering. The sintering tablets were charcterised for their physical parameters and conducted in vitro dissolution tests. The sintering time markedly affected the drug release properties of EVA (ethylene vinyl acetate copolymer) matrices. It is notable that the release rate of rifampicin from EVA matrices was inversely related to the time of sintering. This may be due to the increase in the extent and firmness of sintering which compacts the mass further so that the drug release is affected. The cumulative percent of rifampicin release decreased as the sintering temperature was increased, for all formulations. The drug release follows diffusive mechanism with first-order release kinetics.
An Experimental Investigation into the Off-State Viscosity of MR Fluids

This study investigates the off-state rheological characteristics of magnetorheological fluids. Various carbonyl iron powder grades are tested, both micron- and nano-sized. The study considers both unimodal and bimodal MR fluid samples. The bimodal MR fluids are both micron-sized only compositions and mixed micron- and nano-sized compositions. All fluid compositions employ a novel PFPE oil as a base fluid. This base fluid is introduced and its qualities discussed. An off-state experimental investigation is conducted, for shear-rates from 0 to 200 s−1. All samples exhibit the well-known shear-thinning property of MR fluids, but with varying proportions. The off-state viscosity is of importance in a particular application, in an MR prosthetic knee. It determines how fast the knee joint can rotate in the absence of a magnetic field. A prominent MR fluid composition is selected for the proposed application which aims to maximize to rotational speed of the MR knee joint in the absence of a magnetic field.
ZEOLITE-ENCAPSULATED CU(II)-SALEN COMPLEX AS A CATALYST FOR OXIDATION OF CYCLOHEXANOL

Cu (salen) complex encapsulated in zeolite Y is characterized by elemental analysis, IR, UV-vis and ESR spectroscopy and is shown to be a catalyst for the selective oxidation of cyclohexanol to cyclohexanone in the presence of H 2 0 2 under much milder conditions (80·C) than those in current practice.
The Value of C-Reactive Protein, C-Reactive Protein Kinetics and C-reactive Protein to Albumin Ratio on Prognosis in Newly Diagnosed Indolent B-cell Non-Hodgkin Lymphoma

Objective: This study aimed to determine prognostic significance of C-reactive protein (CRP), CRP kinetics and CRP to albumin ratio (CAR) in indolent B-cell non-Hodgkin lymphoma (B-iNHL) patients. Methods: The association among these blood makers and overall survival (OS), disease-free survival (DFS), progression-free survival (PFS) were analyzed in 243 B-iNHL patients. OS, DFS and PFS were determined by Kaplan–Meier curves. Cox proportional analysis was performed to examine the prognostic significance of clinicopathological variables. Results: Multivariate analyses identified that elevated pretreatment CRP (HR: 5.110, 95% CI: 1.904-13.717, p=0.001), post-treatment CRP (HR: 5.826, 95% CI: 1.659-20.458, p=0.006), continuously elevated CRP (HR: 6.461, 95% CI: 2.620-15.930, p<0.001) and elevated CAR (HR: 3.768, 95% CI: 1.415-10.034, p=0.008) had association with worse OS. Likewise, elevated pretreatment CRP (HR: 3.767, 95% CI: 1.777-7.984, p=0.001), post-treatment CRP (HR: 2.384, 95% CI: 1.027-5.534, p=0.043), ever-elevated CRP (HR: 2.425, 95% CI: 1.105-5.322, p=0.027), continuously elevated CRP (HR: 4.748, 95% CI: 2.114-10.660, p<0.001) and elevated CAR (HR: 2.824, 95% CI: 1.336-5.971, p=0.007) were in independent significance with worse DFS. Elevated pretreatment CRP (HR: 2.606, 95% CI: 1.338-5.076, p=0.005), ever-elevated CRP (HR: 2.086, 95% CI: 1.040-4.188, p=0.039), continuously elevated CRP (HR: 3.296, 95% CI: 1.594-6.818, p=0.001) and elevated CAR (HR: 1.991, 95% CI: 1.021-3.882, p=0.043) were determined in independent significance with poor PFS. The effect was statistically significant in both follicular lymphoma (FL) and chronic lymphocytic leukemia/ small lymphocytic lymphoma (CLL/ SLL) patients.Conclusions: In conclusion, we demonstrate that CRP level, CRP kinetics and CAR could be potential prognostic indicators with independent significance in patients with B-iNHL, also in FL and CLL/ SLL subgroups. CRP and CAR make an implementation for prognostic evaluation more easily and effectively in B-iNHL patients.
Visualizations of Combinatorial Entropy Index on Whole SARS-CoV-2 Genomes

In this paper, a set of SARS-CoV-2 genomes from four countries are selected for visualizations under the C1 modules of the metagenomic analysis system MAS. Based on the variant construction and the theory of information entropy, the module makes statistics on the number of bases in SARS-CoV-2 sequences to calculate the base probability measures in segments to generate the combinatorial entropy index data from the base probability measures. Under visualization technology, the combinatorial entropy index is projected on 2D clustering genomic index maps and 1D histogram maps to provide projection results. The visual results provide intuitive and easy properties to analyze complicated clustering among genomes to support clustering analysis of SARS-CoV-2 genomes in batches, showing the distribution characteristics of SARS-CoV-2 genomes in different countries or regions conveniently.
Frequency of cell treatment with cold microwave argon plasma is important for the final outcome

The purpose of this work was to establish the influence of a regime of cold microwave argon plasma treatments on the physiological characteristics of human fibroblasts and keratinocytes. We used three regimes of plasma application: a single treatment, double treatment with a 48 h interval, and daily treatments for 3 d. Cell proliferation after plasma application was quantified in real time, and immunohistochemistry was used to establish the viability of the cells and determine changes in their physiology. It was established that the frequency of cell treatments is important for the outcome. In the samples treated with single plasma application and double plasma applications with a 48 h interval, a 42.6% and 32.0% increase was observed in the number of cells, respectively. In addition, there were no signs of deoxyribonucleic acid breaks immediately after plasma application. In contrast, plasma application increased the accumulation of cells in the active phases of the cell cycle. The activation of proliferation correlated with a decrease in the level of β-galactosidase, a senescence marker. This could be due to cell renovation after plasma application. Daily treatment decreased cell proliferation up to 29.1% in comparison with the control after 3 d.
Baduanjin Exercise May Improve the Anxiety and Insomnia in COVID-2019 Patients: A Case-Control Study

Background: Since December 2019, an epidemic caused by novel coronavirus(2019-nCoV) infection has occurred unexpectedly in China. Because of the sudden nature of the outbreak and the infectious power of the virus, it will inevitably cause people anxiety and other stress reactions. Previous studies showed that Baduanjin exercise was effective for people in anxiety and insomnia. The purpose of this study was to evaluate the potential benefits of Baduanjin exercise on the anxiety and insomnia in COVID-2019 patients.Methods: This is a Case-Control Study. The COVID-2019 patients including 39 Baduanjin exercises or willing to do Baduanjin exercises and 39 age-and gender-matched nonexercising controls. The anxiety and insomnia in COVID-2019 patients were measured by using the GAD-7 and SMH Sleep Questionnaire at baseline and discharge.Results: In the study, the Paired T-test showed that two groups had improved the GAD-7 scores and SMH Sleep Questionnaire compared with baseline at discharge. Baseline results showed there were no significant differences in the GAD-7 scores and SMH Sleep Questionnaire between the two groups. However, the significant differences found in the Baduanjin group included a 43.9% lower (p<0.001) in the GAD-7 score and an approximately 75.9% higher (p=0.003) in SMH Sleep Questionnaire score compare with the control group at discharge.Conclusion: The Baduanjin exercise may improve the anxiety and insomnia in COVID-2019 patients. It can also be used as a form of rehabilitation exercise for discharged patients or patients isolated at home.Trial Registration: ChiCTR2000030528.
Optimization of biodegradable polymeric submicroparticles preparation

The influence of various surfactants and their combinations on the particle diameter and particles size distribution during their preparation from biodegradable poly(lactide acid) by the method of emulsification and solvent evaporation at reduced pressure was investigated. The attention was focused on the possibility to control the size of resultant particles by hydrophilic-lipophilic balance parameter (HLB), which is a characteristic of nonionic surfactants. First, nonionic surfactants were combined to obtain various HLB values of the system and then combinations with the biodegradable surface active polymer Gelatin A were assayed. Gelatin A proved to be a suitable emulsion stabilizer in the process of PLA submicroparticles preparation and it was found that to achieve PLA submicroparticles with the lowest diameter and narrow distribution HLB of the system has to be set up under about 16. For combinations of gelatin A and another nonionic surfactant the reduction of the aggregate HLB value of the system could better be achieved with an addition of a surfactant having HLB closer to the optimum like Tween 20 or Tween 85.
