Simultaneous determination of several crystal structures from powder mixtures: the combination of powder X-ray diffraction, band-target entropy minimization and Rietveld methods

Crystal structure determination is the key to a detailed understanding of crystalline materials and their properties. This requires either single crystals or high-quality single-phase powder X-ray diffraction data. The present contribution demonstrates a novel method to reconstruct single-phase powder diffraction data from diffraction patterns of mixtures of several components and subsequently to determine the individual crystal structures. The new method does not require recourse to any database of known materials but relies purely on numerical separation of the mixture data into individual component diffractograms. The resulting diffractograms can subsequently be treated like single-phase powder diffraction data, i.e. indexing, structure solution and Rietveld refinement. This development opens up a host of new opportunities in materials science and related areas. For example, crystal structures can now be determined at much earlier stages when only impure samples or polymorphic mixtures are available.
Three is a Magic Number: Evidence on the Effects of the Application of the Three-Point Rule in Italy’s Serie A

This paper contributes to the expanding literature that investigates the effects of the introduction of a three-points-for-a-win rule in football. To this end, it provides empirical evidence of the effect of the rule on Italy’s most prestigious football league. Our analysis uses data collected over a long period of time and relies on pooled regressions and a regression discontinuity design. The findings provide evidence that in the case of the Italian league the rule worked as expected, unlike what previous contributions have found when looking at other national football leagues.
Dynamics of dwarf bamboo populations and tree regeneration over 40 years in a clear-cut beech forest: effects of advance weeding and herbicide application

ABSTRACT We explored the dynamics of dwarf bamboo populations in a beech forest 11 years before and 30 years after clear-cutting. Repeated weeding or herbicide application (sodium chlorate) was used experimentally to reduce or eliminate dwarf bamboo prior to clear-cutting. At the beginning of the study, the understory comprised dense populations of two Sasa species, the dominant S. palmata and the less common S. kurilensis. Both weeding and herbicide application rapidly reduced the cover of S. palmata, but it began to recover prior to clear-cutting and soon exceeded initial cover values. Both weeding and herbicide application reduced the cover of S. kurilensis to near-negligible levels; the cover increased slowly after clear-cutting but remained below initial levels. Weeding or herbicide application resulted in different patterns with respect to height; height decreased rapidly in response to weeding, whereas herbicide application had more gradual effects. Height began to increase after clear-cutting, and S. palmata exceeded its initial height, reaching 1.5–2.0 m in the 10–15 years following clear-cutting. No tree recruits were found in sites where dwarf bamboo was left unmanaged. Weeding and herbicide application facilitated recruitment of Betula ermanii after clear-cutting, but recruits of Fagus crenata, which originally dominated the forest canopy, remained scarce or non-existent at 30 years after clear-cutting. We postulate that natural regeneration of Fagus is nearly impossible following clear-cutting in temperate beech forests in Japan with dense undergrowth of Sasa, even with advance measures to reduce or eliminate Sasa.
“Traditions Are Not for Me”: Curriculum, Alternative Schools, and Formerly Incarcerated Young Black Men’s Academic Success

Literature suggests that culturally promotive curricula can counter the effect of anti-Blackness in United States (U.S.) schools by cultivating Black students’ cultural, social, and academic development and fostering learning environments in which they feel respected, connected, and invested in their school communities. However, Black students, especially young Black men, who return to school following a period of incarceration, face discrimination and numerous barriers to school reentry and engagement. While some enroll in alternative schools as a last option to earn a diploma, little is known about how curricula in these educational settings can facilitate positive school reentry experiences and outcomes among this population. As such, this intrinsic qualitative case study explored how one alternative school’s culturally promotive curriculum fosters and cultivates educational resilience among formerly incarcerated young Black men. Data collection included observations, interviews, and document reviews, and utilized a thematic analytic approach that included grounded theory techniques. Results indicate that teaching content that formerly incarcerated young Black men perceived as truthful and relevant to their lived experiences augmented their school engagement. The young men reported feeling empowered by the school’s curriculum structure and culture that allowed them to self-direct learning goals and course content toward themes that affirmed their cultural and social identities. The curriculum also appeared to facilitate positive relationships with the instructors, leading to the development of a positive school climate where the young men felt safe, appreciated, and supported. These findings highlight the important role space, place, and relationships can play in bolstering formerly incarcerated young Black men’s educational resilience through a culturally promotive curriculum in the context of an alternative school.
Metodologia para determinação das classes de risco de incêndio florestal usando a Fórmula de Monte Alegre modificada

The objective of this study was to calculate the Modified Monte Alegre Formula (FMA⁺) and adjust the wildfire risk classes of areas of forests planted in the northern-central coast of the state of Espirito Santo state and the southern coast of Bahia state. The methodology used included six stages: risk calculation; spreadsheet development according to the occurrence, or not, of forest fires; spreadsheet development according to the wildfire season in the study region; risk class definition; result analysis of the determined classes; best fit selection. It was observed that the class definition methodology for the FMA⁺ system obtained excellent results. It increased by 19.3, 21.53, and 31.3% for the percentage of success for subzones 1, 2, and 3, respectively, which implies this an important study for the successful implementation of FMA⁺ in other areas.
Air Quality Trends amid Covid-19 Lockdown in Metro Manila, Philippines: A Preliminary Case Review

CoVID-19 pandemic forced a countrywide lockdown in the Philippines from March 16, 2020 to May 15, 2020 and extended to May 31, 2020 in Metro Manila and some parts of Central Luzon. Because of these forced restrictions, the air pollution level in Metro Manila drastically slowed down just a few weeks upon the implementation of the lockdown. Therefore, this study aimed to establish a preliminary case review on the implications of the lockdown to the air quality in the country’s capital with the aid of data from the Centre for Research on Energy and Clean Air (CREA) and Airtoday.ph station. The empirical analysis revealed that when Metro Manila was under Enhanced Community Quarantine (ECQ), tropospheric nitrogen oxide (NO2) dropped by approximately 52% compared to the 2019 levels in the same period. The city also registered the lowest PM 2.5 air pollution levels during the first 30 days of the lockdown with an average of 11.59 ug/m3. Moreover, the satellite image from the Institute of Environmental Science and Meteorology (IESM), UP Diliman showed a lower Atmospheric Optical Depth (AOD) of 0.01, which means that the air is clean during the lockdown period when compared with the AOD value during the same period in 2018 and 2019. At the Lung Center of the Philippines, a comparison of pre-ECQ and ECQ air quality levels showed that PM2.5 is reduced from 80% to 180%, particularly during evenings and early mornings. A similar trend along EDSA Munoz, where 70-90% reduction of PM 2.5 was observed since the ECQ. Overall, the study revealed that lockdown measures, fortunately, have brought the opportunity to rationalize human impact on the environment. Although we could say those travel restrictions or lockdown is an unconventional measure to air pollution prevention and control, it is possible to improve air quality by reducing nonessential individual movements by highlighting the importance of fuel-free activities or implementing short-term lockdowns (3-5 days).
Development and validation of a machine learning‐based postpartum depression prediction model: A nationwide cohort study

Currently, postpartum depression (PPD) screening is mainly based on self‐report symptom‐based assessment, with lack of an objective, integrative tool which identifies women at increased risk, before the emergent of PPD. We developed and validated a machine learning‐based PPD prediction model utilizing electronic health record (EHR) data, and identified novel PPD predictors.
Clinical efficacy of low-dose emetine for patients with COVID-19: a real-world study

Abstract Objective: Emetine, an isoquinoline alkaloid that is enriched at high concentrations in the lung, has shown potent in vitro activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The aim of this study was to better understand the effectiveness of low-dose emetine for patients with coronavirus disease 2019 (COVID-19). Methods: In this real-world study, 63 patients with mild or common COVID-19 were recruited from Wuhan Fangcang Shelter Hospital and five COVID-19-designated hospitals in Anhui Province, China from February to March 2020. Thirty-nine patients from Wuhan Fangcang Shelter Hospital were assigned to a pragmatic randomized controlled clinical trial, and 24 patients from the 5 COVID-19-designated hospitals in Anhui Province underwent a real-world study. The medication course of emetine was less than 10 days. The main symptoms and adverse reactions of all patients were observed and recorded. The primary outcome measure was the time required for a negative SARS-CoV-2 RNA result or the negative result rate on day 10. Secondary outcomes included axillary temperature, transcutaneous oxygen saturation, and respiratory frequency recovery. The study was approved by the Ethics Committee of The First Affiliated Hospital of Anhui Medical University on February 20, 2019 (approval No. PJ2020-03-19) and was registered with the Chinese Clinical Trial Registry on February 20, 2019 (registration number: ChiCTR2000030022). Results: The oxygen saturation values were higher in the treatment group than in the control group on the first day after enrollment for patients treated at Fangcang Shelter Hospital. The axillary body temperature, respiratory rate, and oxygen saturation among patients in Fangcang Shelter Hospital were related to the time effect but not to the intervention measures. The respiratory rate and oxygen saturation of patients in the Anhui designated hospitals were related to the intervention measures but not to the time effect. The axillary body temperature of patients in Anhui designated hospitals was related to the time effect but not to the intervention measures. Conclusion: Our preliminary study shows that low-dose emetine combined with basic conventional antiviral drugs improves clinical symptoms in patients with mild and common COVID-19 without apparent adverse effects, suggesting that moderately increased doses of emetine may have good potential for treatment and prevention of COVID-19.
STUDENT SATISFACTION VS STUDENT ACHIEVEMENTS – SHOULD QUALITY MANAGEMENT SYSTEM IN HIGHER EDUCATION AIM AT STUDENT SATISFACTION OR STUDENT ACHIEVEMENTS?

Purpose – The paper emphasises the importance of student development and claim that quality assurance processes at the higher education institutions are not responding to the challenges related to the student engagement. The premise is that student satisfaction is insufficient indicator of quality and that quality processes should focus on student development. Design/Methodology/Approach – The propositions in the paper are based on extensive literature review and are tested on a sample of 1378 students from 61 Croatian higher education institutions. Relationships in the model are tested using hierarchical linear model. Findings and implications The results of this paper enabled understanding the individual and institutional determinants that encourage students to engage in educationally purposeful activities. Teachers and administrators in higher education can use the results to design their processes to assure high levels of students’ achievements. The policy makers can use it to promote the activities that are critical for students’ development. Limitations – The survey was conducted in Croatian HE system and variables at the institutional level were adjusted due to the lack of data. Consequently, the institutional effect is underestimated and research results at the second level of analysis were insignificant. Originality – The paper emphasises the need to reconsider quality assurance processes in higher education to be oriented more toward student development and
Experimental studies of the core excitation of imidazole, 4,5-dicyanoimidazole, and s-triazine

The C and 1s and N 1s core level spectra of solid imidazole (IM) and 4,5-dicyanoimidazole (DCIM) have been recorded with ultrasoft X-ray absorption spectroscopy (USXAS) by using both total electron yield (EY) and fluorescence yield (FY) detection methods. IM, DCIM, and s-triazine (TZ) were studied in the gas phase by using inner-shell electron energy loss spectroscopy (ISEELS). USXAS and ISEELS show sensitivity to core level shifts, especially for 1M at the nitrogen edge, where the two main N 1s→π * resonances are observed with a separation on the order of the core level shifts. The N 1s→π * separation changes from 2.4 eV in the gas phase to 1.4 eV in the solid
A measurement of epidermal thickness of fingertip skin from OCT images using convolutional neural network

In this study, we proposed a method to measure the epidermal thickness (ET) of skin based on deep convolutional neural network, which was used to determine the boundaries of skin surface and the ridge portion in dermal–epidermis junction (DEJ) in cross-section optical coherence tomography (OCT) images of fingertip skin. The ET was calculated based on the row difference between the surface and the ridge top, which is determined by search the local maxima of boundary of the ridge portion. The results demonstrated that the region of ridge portion in DEJ was well determined and the ET measurement in this work can reduce the effect of the papillae valley in DEJ by 9.85%. It can be used for quantitative characterization of skin to differentiate the skin diseases.
Interactions of ion beams with surfaces. Reactions of nitrogen with silicon and its oxides

Ion beam studies of chemical reactions between nitrogen and surfaces of silicon and its oxides are reported. A spectrometer system designed for these studies which combines the techniques of x‐ray and uv photoelectron spectroscopy, Auger electron spectroscopy, secondary ion mass spectroscopy, low energy electron diffraction, and ion bombardment is described. This work employs XPS and UPS to examine the products induced by 500 eV N+2 beams on targets of elemental Si, SiO, and SiO2. The N+2 ions undergo charge exchange and dissociation at the surface of the target to form hot N atoms. Reaction with Si, produces nitrides which are similar to those of the type Si3N4. Reaction with SiO and SiO2 forms nitrides, with no evidence of nitrate or nitrite formation. The chemical nature of the reaction is suggested by identification of the reaction products through XPS and UPS and energy level shifts. The thickness of the silicon nitride layer on Si(111) formed by 500 eV N+2 bombardment has been determined to be ∼19 A.

Inflammatory biomarkers and tumoral growth factors are modulated by exercise in breast cancer survivors

Introduction: Insulin-like growth factors (IGF ́s) play a crucial role in controlling cancer cell proliferation, differentiation and apoptosis. Exercise has been postulated as an effective intervention in improving cancer-related outcomes and survival, although its effects on IGF ́s are not well understood. This meta-analysis aimed to determine the effects of exercise in modulating IGF ́s system in breast cancer survivors. Methods: Databases of PuMed, EMBASE, Cochrane Central Register of Controlled Trials, EMBASE, ClinicalTrials.gov, SPORTdiscus, LILACS and Scopus were systematically searched up to November 2014. Effect estimates were calculated through a random-effects model of metaanalysis according to the DerSimonian and Laird method. Heterogeneity was evaluated with the I test. Risk of bias and methodological quality were evaluated using the PEDro score.
In-hospital emergencies versus out-of-hospital emergencies admitted to ICU: is the outcome different? An observational study

Background: Rapid Response Systems (RRS) are now commonly implemented throughout hospital health systems to manage in-hospital emergencies (IHE). There is limited data on characteristics and outcomes of such patients admitted to an intensive care unit (ICU). The goal was to determine whether the hospital mortality of ICU patients was different depending on their admission pathway: in-hospital via rapid response teams (RRT), or out-of-hospital emergencies (OHE) via prehospital emergency medical systems. Results: Out of 422 ICU admissions (Timone University Hospital ICU), 241 patients were retrospectively (2019-2020) included: 74 IHE versus 167 OHE. In-hospital mortality rates did not differ between both cohorts (n = 31(42%) vs. 63(39%) respectively, NS). IHE patients were older and had more comorbidities (immunosuppression and ongoing malignancy). OHE patients had more severe organ failures at presentation with more frequent mechanical ventilation support. Independent global hospital mortality risk factors were ongoing malignancy (OR = 10.4 [2.7-40], p < 0.001), SAPS II (OR = 1.05 [1.03-1.08], p < 0.0001) and SOFA scores (OR = 1.14 [1.01-1.3], p < 0.05), hemorrhagic stroke as admission diagnosis (OR = 8.4 [2.7-26], p < 0.001), and arterial lactate on arrival (OR = 1.11 [1.03-1.2], p < 0.01). Conclusion: This study provides a thorough and comprehensive analysis of characteristics and outcomes of ICU admissions following a mature rapid response activation system, compared to the “conventional” out-of-hospital admission pathway. Despite the more vulnerable background of IHE patients, hospital mortality does not differ, supporting the use of early RRS to identify deteriorating ward patients. Take-home message: Hospital mortality does not differ between in-hospital emergencies admitted to intensive care unit and conventional out-of-hospital admissions, supporting the use of early rapid response systems and the importance of early intensive care unit admission.
Changes in Community Composition of Tropical Evergreen Forests during Succession in Ta Dung National Park, Central Highlands of Vietnam

Degradation of tropical forests is a major driver of the global extinction crisis. A key question is understanding the role of evolution history during forest succession in the context of forest restoration for maintaining ecosystem function and stability. This study was conducted in a fragmented forest landscape in the central highlands of Vietnam. We sampled living trees with diameters at breast height of ≥6.0 cm in nineteen 0.25 ha plots to evaluate forest community structure changes over two early successional stages (<10 years and 10–20 years old) after abandonment and old-growth. We used both statistically metric and nonmetric analyses to examine correlations of community composition during successional stages and along elevational gradients. We found that (i) significant differences existed in the structural compositions between early successional forests and old-growth forests, but did not exist within early successional forests; (ii) the phylogenetic structure shifted from overdispersion to clustering with increasing successional ages; and (iii) above-ground biomass (AGB), representing ecosystem functioning, significantly increased from early-to-late successional stages, but did not correlate with phylogenetic diversity or elevation. Our results revealed that the forest community structure was strongly affected by degradation, particularly AGB and phylogenetic structure. These findings have clear implications for sustaining biodiversity persistence and ecosystem functioning in human-modified landscapes in the study region.
Instability and dewetting of evaporating thin water films on partially and completely wettable substrates

Stability, dynamics and dewetting of thin (<100 nm) evaporating water films on partially and completely wettable substrates are studied based on numerical solutions of the nonlinear thin film equation, as well as by simplified semianalytical approaches. The instability and rupture of aqueous films are engendered by the hydrophobic attraction, whereas the net van der Waals force is repulsive for aqueous films on most substrates. An evaporating aqueous film on a partially wettable surface thins uniformly to a critical thickness, and then spontaneously dewets the substrate by the formation of growing holes. Complete nonlinear simulations as well as the linear analyses are used to predict the most important, experimentally accessible characteristics of the instability such as the length scale and time scale of the instability and the mean film thickness at the instant of rupture. Curiously, in contrast to nonthinning films, the number density of holes decreases slightly with increased strength and range of hy.
Nephrolepis exaltata - Hibiscus rosa-sinensis combination herbal mask decreases levels of reactive oxygen species in nasal wash

BACKGROUND Poor air and mask quality in the work environment increase the risks of inflammation, reactive oxygen species (ROS) production, ongoing oxidative stress, and superoxide dismutase 3 (SOD3) levels in the airways. The study aimed to investigate the effect of the Nephrolepis exaltata Hibiscus rosa-sinensis (NE-HRS) combination herbal mask on the airways, as measured by ROS and SOD3 levels in the nasal wash of textile industry workers.
