Improving the reliability of Fe- and S-XANES measurements in silicate glasses: correcting beam damage and identifying Fe-oxide nanolites in hydrous and anhydrous melt inclusions

The redox state of silicate melts influences crystallization, element partitioning, and degassing behavior. Synchrotron-based micro-X-ray absorption near edge structure (μXANES) spectroscopy has emerged as a powerful tool for determining redox conditions through the direct measurement of speciation of multivalent elements such as iron and sulfur in silicate glasses. In particular, the high spatial resolution afforded by synchrotron μXANES makes it one of the few techniques available for determining redox conditions in melt inclusions, which can provide insights into pre-eruptive melt properties. However, the small size of melt inclusions, the deep penetration of X-rays, and irradiation-induced beam damage make μXANES measurements in melt inclusions challenging. Here we present data that show rapid Fe- and S-μXANES beam damage in experimental glasses, mid-ocean ridge basalt glasses, and olivine-hosted melt inclusions from the southern Cascade arc and Kīlauea Volcano and develop approaches to recognize and correct for beam damage through repeated rapid analyses. By applying a time-dependent correction to a series of rapid measurements (~82 s/scan) of Fe-μXANES pre-edge centroid positions, irradiation-induced photo-oxidation (Fe2+ to Fe3+) can be corrected back to undamaged initial Fe3+/ΣFe even in damage-susceptible hydrous glasses. Using this beam damage correction technique, hydrous basaltic melt inclusions from the southern Cascades have Fe3+/ΣFe that is ~0.036 lower (corresponding to -0.5 log units lower oxygen fugacity) than would have been indicated by standard Fe-μXANES measurements. Repeated, rapid analyses (150 – 300 s/scan) were used to identify S-μXANES beam damage (photo-reduction of S6+ to S4+), which was corrected with a peak fitting method to restore initial S6+/ΣS. We observe that S-μXANES beam damage can occur rapidly even in low-H2O mid-ocean ridge basaltic glasses and melt inclusions from Kīlauea Volcano, which are otherwise stable during even prolonged Fe-μXANES analyses. By mitigating and correcting for sulfur photo-reduction, we conclude that some mid-ocean ridge basaltic glasses contain 0.08 – 0.09 S6+/ΣS, which is more sulfate than might be expected based on the reduced oxidation state of these glasses (near the fayalite-magnetite-quartz oxygen buffer). Using beam damage identification and correction techniques, the valence states of iron and sulfur can be accurately measured even in beam damage-susceptible glasses and melt inclusions. Finally, using Fe-μXANES, we demonstrate the presence of Fe-oxide nanolites within otherwise glassy, naturally quenched melt inclusions, which can complicate determination of iron valence state in affected glasses.
Visual and aesthetic markers of gentrification: agency of mapping and tourist destinations

Abstract Framed within the context of contemporary place making and the urban tourism destination, a novel trans-disciplinary approach to mapping and interpreting gentrification and cityscape change is presented. A combination of multi-scalar cartographic and visual techniques, including Google Street View (GSV) and geo-tagged images (Photo Sphere), is applied within the setting of Valletta, Malta, to convey cartographically the dynamism of urban transformations and detect tourism-led gentrification in a rapid way through the identification of the visual and aesthetic markers of gentrification. Utilising a critical approach, such map-making can inform and transform the understanding of the processes underpinning urban change and their cartographic and visual representation. It identifies and highlights issues of image and street-level ‘realities’ for both (re)imagining and marketing place. Individual tourists are able to access and utilise GSV and other mobile digital imaging and cartographic tools, as well as social media, to create their own, potentially counter, place-imaginaries and interpretations of urban change, thereby encouraging and/or discouraging visiting the city.
THE IMPACT OF PANDEMIC CORONA VIRUS ON COMMUNICATION IN TOURISM

Communication and information technologies have greatly influenced the changes of tourism as an activity, especially when it comes to distribution channels in tourism, achieving more accurate and closer communication with customers/tourists, easier access to information, which ultimately affected the creation of market competition with the focus on the tourist. Communication in the tourism industry is of universal importance if the goal is an adequate level of tourist satisfaction as well as competitiveness in the local and global market. Communication is not just promotional activity aimed at attracting tourists, but the totality of relationships that are realized before arrival, during staying and after the departure of tourists, and their quality determines the ratio of expected and achieved satisfaction of a service user. The aim of the research is to understand the different effects that communication (verbal and non-verbal) has in restrictive business conditions. In addition, the paper seeks to point out the practical aspects of the communication process of all participants, directly or indirectly, involved in the creation and provision of services in the tourism industry, with reference to the time of the pandemic.
Towards Representative Web Performance Measurements with Google Lighthouse

Web performance testing with tools such as Google Lighthouse is a common task in software practice and research. However, variability in time-based performance measurement results is observed quickly when using the tool, even if the website has not changed. This can occur due to variability in the network, web, and client devices. In this paper, we investigated how this challenge was addressed in the existing literature. Furthermore, an experiment was conducted, highlighting how unrepresentative measurements can result from single runs; thus, researchers and practitioners are advised to run performance tests multiple times and use an aggregation value. Based on the empirical results, 5 consecutive runs using a median to aggregate results reduce variability greatly, and can be performed in a reasonable time. The study’s findings alert to p otential pitfalls when using single run-based measurement results and serve as guidelines for future use of the tool.
Protocol for a cross-sectional study on factors affecting health-related quality of life among Afghan refugees in Pakistan

Background: Pakistan served as a host for more than 1.4 million Afghan refugees for more than 40 years. Access to health care is the most important issue faced by refugees, because they might be at a higher risk for certain diseases. This risk can be attributed to a lack of awareness of health care facilities, health beliefs, inadequate hygiene, cultural differences, and malnutrition. Health of individuals is closely associated with their quality of life. Quality of life over the whole lifespan is pivotal to overall life satisfaction. It includes physical wellbeing, mental health, education, occupation, income, personal safety, as well as (religious) freedom. Until now, the health status of Afghan refugees has never been comprehensively investigated in Pakistan. Therefore, an assessment in this regard is needed to explore their health-related quality of life, for securing their human right to health. Methods: A cross-sectional study has been designed to describe and explain the health-related quality of life of Afghan refugees in Pakistan. Multistage cluster sampling was applied for selection of study participants. The number of respondents from two regions in Pakistan was drawn through a proportionate sampling technique. A quantitative research method using pre-validated questionnaires was used for data collection. The questionnaire included items to assess well-being, mental health, health literacy, and factors affecting health and health care. Descriptive analysis was used, whereas inferential statistical tests (binary logistic regression model) was also performed. The study received ethically permission by the Advanced Studies and Research Board of the University of the Punjab, Lahore, Pakistan. Discussion: The assessment of Afghan refugee’s quality of life in Pakistan should lead to recommendations disseminated to public and health care officials. This evidence is needed for policymaking related to adequate measures for improving health conditions of Afghan refugees in Pakistan.
Roles of the Ratio of C-Reactive Protein to Serum and Pericardial Fluid Albumin Levels in Predicting in-Hospital Mortality in Patients Undergoing Pericardiocentesis

Background: Pericardial effusions occur due to excessive fluid accumulation in the pericardial space. In effusions not responding to medical treatment, pericardiocentesis is an important method of treatment affecting prognosis. CRP/albumin ratios have been found to be associated with prognosis in conditions such as cardiac failure, sepsis, malignancy, and the routinely available parameters used for the prognosis prediction of the patients who underwent pericardiocentesis are limited. This study aimed to examine the usability of CRP/albumin and CRP/pericardial fluid albumin (CRP/pf-albumin) ratios as predictors for in-hospital mortality of patients who underwent surgery pericardiocentesis. Methods: This study included 54 patients (25 females and 29 males). All patients underwent pericardiocentesis. Results: The average age was 67±14 years. When the groups were compared with each other, CRP, CRP/albumin ratio and CRP/ pf-Albumin ratio were higher in the in-hospital mortality group compared to the group discharged with recovery [19 (14-25), 6.3 (1-30), p<0.001; 4.27 (3.87-12.02), 1.9 (0.24-10.38), p<0.001; 7 (6.25-13.59), 2.5 (0.28-12.22), p<0.001, respectively]. In the univariate logistic regression analysis, CRP (odds ratio [OR]: 0.821, P: 0.004, 95.0% confidence interval [CI]: 0.918-1.049), CRP/albumin ratio (OR: 0.600, P: 0.011, 95.0% CI: 0.406-0.888) and CRP/pf-Albumin ratio (OR: 0.608, P: 0.004, 95.0% CI: 0.431-0.856) was found to be associated with in-hospital mortality in patients who underwent pericardiocentesis. Conclusion: For the first time in the literature, we demonstrated that CRP/albumin and CRP/pf-Albumin ratios are associated with in-hospital mortalities in patients who underwent pericardiocentesis, irrespective of the etiology.

Production and Screening of Streptomyces-Extracellular Chitinase

The aim of this research was to produce Streptomyces-extracellular chitinase and screen its antifungal activity on a clinically isolated Candida albicans. The Streptomyces were isolated from an agricultural farmland; they were identified and screened for the chitinase production. Effects of time, temperature, pH and nitrogen sources on the chitinase production were determined using standard methods. Ammonium sulphate precipitation was used to partially purify the chitinase. Protein concentrations were determined spectrophotometrically using bovine serum albumin as standard. Agar-well diffusion method was used to evaluate the antifungal activity of the chitinase on C. albicans. The isolated Streptomyces were of three (3) strains, and all the strains are Gram positive, catalase positive, oxidase positive while, Strain A and C are indole positive and only Strain B is citrate positive. The maximum chitinase production was at 72 h, 40°C and when yeast extract was used as the nitrogen source. Ammonium sulphate (80%) precipitation yielded the highest enzyme activity of 39.0U/ml. The maximum enzyme activity was observed at temperature of 40oC, pH 5.5 and 1.0% colloidal chitin (substrate). The partially purified chitinase showed a zone of inhibition of 20.11 ± 1.26 mm against the Candida albicans. This result has no significant difference (P>0.05) when compared with that of the standard drug (Fluconazole) with 21.42 ± 0.08 mm zone of inhibition. These findings suggest that Streptomyces at favourable conditions produce chitinase, and this enzyme can be used as an antifungal agent on Candida albicans and other chitin containing fungi.

Two field experiments were conducted at the Experimental Research Station, Faculty of Agriculture, Moshtohor, Benha University, Qalyoubia Governorate, Egypt, during 2016/17 and 2017/18 winter seasons this study is to evaluate the effectiveness of four treatments: phosphate fertilization sources as soil addition (super phosphate (SP), rock phosphate (RP) + phosphate dissolving bacteria (PDB), sulphur (S) + phosphate dissolving bacteria (PDB) and RP + S+ PDB) with three spraying levels of lithovit ( 0 , as tap water, 0.5 and 1.0)g/L ), to increase the availability of phosphorus from rock phosphate and their effects on vegetative growth parameters, chemical composition, yield and yield attributes of faba bean plants cv. Sakha 4. Experiments were designed and carried out as split plot design where lithovit as foliar application levels randomly distributed in the main plots and phosphorus fertilization sources were in the split plots of three replicates. Results determined as follows: Application of different phosphate fertilization sources induced significant increases growth characteristics, yield, its components, and chemical constituents of faba bean (Sakha 4). In addition, Fertilizer application of RP + S + PDB formed the tallest plant heights, No. of branches / plant, chlorophyll content, yield and its components and seed index as well in the two respective seasons with variable significant magnitudes. Also, Nitrogen (%), Phosphorus (%) and Potassium (%) were increased in the 1 st season where fertilized with RP + S + PDB. Foliar application of lithovit, 1.0 g/L level exerted the highest values of growth characteristics, yield, its components, and chemical constituents of faba bean (Sakha 4) as well in each of the two growing seasons with different significant magnitudes.
Development of soil test crop response based fertilizer prescriptions through integrated plant nutrition system for aggregatum onion (Allium cepa L.) under drip fertigation

An insight into the balanced crop nutrition and efficient irrigation will be rewarding to attain profitable bulb yield of shallow-rooted and high nutrient requiring aggregatum onion. To develop fertilizer prescription equations(FPEs) for aggregatum onion under drip fertigation by encompassing the Soil Test Crop Response approach (STCR), a field experiment was conducted in Palaviduthi soil series with 15 treatments viz., Absolute control (T1), Blanket recommendation (60:60:30) + Farm Yard Manure (FYM) @ 12.5 t ha-1(T2), STCR based NPK fertilizer recommendation (STCR-NPK) for the targeted yield of 14 (T3),15 (T4),16 t ha-1 (T5), FYM @ 6.25 (T6), 12.5 t ha-1 (T7), STCR–NPK+FYM @ 12.5 t ha-1 for the targeted yield of 14 (T8),15 (T9),16 t ha-1 (T10), Biocompost @ 2.5 (T11), 5 t ha-1 (T12) and STCR–NPK+Biocompost @ 5 t ha-1 for the targeted yield of 14 (T13),15 (T14),16 t ha-1 (T15). The results revealed that T10 was more supercilious than others. The basic parameters were deliberated from the experimental data on total nutrient uptake, initial soil fertility status, applied fertilizer doses. The aggregatum onion (variety CO 4) required 0.43, 0.32, 0.45 Kg of N, P2O5, K2O to produce one quintal of bulb yield. The percent contribution of nutrients from soil and fertilizer was 14.01, 54.57 for N, 35.11,50.50 for P2O5 and 12.69, 70.12 for K2O, respectively. The contribution of N, P2O5, K2O from FYM and biocompost were 41.02, 16.23, 41.53 and 47.98, 15.87, 49.56 percent sequentially. Based on the above parameters, the fertilizer prescription equations were formulated for aggregatum onion under drip fertigation in Palaviduthi soil series.
Topics, Concepts, and Measurement: A Crowdsourced Procedure for Validating Topics as Measures

Abstract Topic models, as developed in computer science, are effective tools for exploring and summarizing large document collections. When applied in social science research, however, they are commonly used for measurement, a task that requires careful validation to ensure that the model outputs actually capture the desired concept of interest. In this paper, we review current practices for topic validation in the field and show that extensive model validation is increasingly rare, or at least not systematically reported in papers and appendices. To supplement current practices, we refine an existing crowd-sourcing method by Chang and coauthors for validating topic quality and go on to create new procedures for validating conceptual labels provided by the researcher. We illustrate our method with an analysis of Facebook posts by U.S. Senators and provide software and guidance for researchers wishing to validate their own topic models. While tailored, case-specific validation exercises will always be best, we aim to improve standard practices by providing a general-purpose tool to validate topics as measures.

Highly Sensitive Luminescent Bioassay Using Recombinant Escherichia coli Biosensor for Rapid Detection of Low Cr(VI) Concentration in Environmental Water

In this study, we constructed a recombinant Escherichia coli strain with different promoters inserted between the chromate-sensing regulator chrB and the reporter gene luxAB to sense low hexavalent chromium (Cr(VI)) concentrations (<0.05 mg/L); subsequently, its biosensor characteristics (sensitivity, selectivity, and specificity) for measuring Cr(VI) in various water bodies were evaluated. The luminescence intensity of each biosensor depended on pH, temperature, detection time, coexisting carbon source, coexisting ion, Cr(VI) oxyanion form, Cr(VI) concentration, cell type, and type of medium. Recombinant lux-expressing E. coli with the T7 promoter (T7-lux-E. coli, limit of detection (LOD) = 0.0005 mg/L) had the highest luminescence intensity or was the most sensitive for Cr(VI) detection, followed by E. coli with the T3 promoter (T3-lux-E. coli, LOD = 0.001 mg/L) and that with the SP6 promoter (SP6-lux-E. coli, LOD = 0.005 mg/L). All biosensors could be used to determine whether the Cr(VI) standard was met in terms of water quality, even when using thawing frozen cells as biosensors after 90-day cryogenic storage. The SP6-lux-E. coli biosensor had the shortest detection time (0.5 h) and the highest adaptability to environmental interference. The T7-lux-E. coli biosensor—with the optimal LOD, a wide measurement range (0.0005–0.5 mg/L), and low deviation (−5.0–7.9%) in detecting Cr(VI) from industrial effluents, domestic effluents, and surface water—is an efficient Cr(VI) biosensor. This unprecedented study is to evaluate recombinant lux E. coli with dissimilar promoters for their possible practice in Cr(VI) measurement in water bodies, and the biosensor performance is clearly superior to that of past systems in terms of detection time, LOD, and detection deviation for real water samples.
Properties of Biocomposites Produced with Thermoplastic Starch and Digestate: Physicochemical and Mechanical Characteristics

This paper presents the results of a study on the influence of the addition of digestate (DG) sludge from an agricultural biogas plant on the mechanical properties of the coating obtained from thermoplastic starch (TPS). The dried, fragmented digestate, some of which had previously undergone ultrasound treatment, is used in the study. Biocomposites are produced by the pouring method using Teflon moulds as matrices. The physicomechanical study included the determination of the basic parameters of the materials obtained. Strength parameters, the contact angle, thermogravimetric properties (TGA), colour and colour difference and moisture absorption are determined. Photographs of the surface of the samples are taken with a scanning electron microscope (SEM) as well. It is found that the addition of the digestate has an advantageous effect on improving the physical and mechanical parameters. In general, samples with digestate also have a higher strength compared to the pure TPS material. The highest tensile strength and Young’s modulus are found in samples with the 14 wt% addition of ultrasound-treated digestate. On the basis of this study, it can be concluded that the addition of digestate is a promising approach for the production of TPS biocomposites with superior mechanical properties.
Occurrence and associated factors of aflatoxin M1 in raw cow milk in South Gondar Zone, North West Ethiopia, 2020

Abstract Aflatoxin M1 is the most significant toxin of milk and milk products. It is immunosuppressive, mutagenic, and carcinogenic compounds to humans. Therefore, this study was aimed to evaluate the concentration of aflatoxin M1 and its determinants in raw cow milk sample intended for human consumption in South Gondar Zone, Ethiopia. A cross‐sectional study was conducted on a total of 100 dairy farmers from January to February 2020. Around 50 ml, 100 raw milk samples were collected for aflatoxin M1 analysis. A simple random sampling technique was applied to get the households. Binary and multivariate logistic regressions were used to see the association between predictor and outcome variables. From the 100 dairy farmers who had participated, 38% had heard about aflatoxin in the milk sample. Aflatoxin M1 was detected in the 99(99%) raw milk samples, of these 41 (41%) exceeded the limit of the European Union. The logistic regression analysis result showed that residence, awareness about the level of aflatoxin in the milk sample, management mold‐contaminated animal feed, animal feed storage facility, and grazing systems were significantly associated with the high level of aflatoxin in the milk sample. Almost all milk samples analyzed were positive for aflatoxin M1, and 41% of samples were above the limit set by European Union. Many easily manageable and preventable factors were associated with higher levels of aflatoxin M1 in the milk sample than the European Union limit, which suggests continuous monitoring of milk and milk products is necessary.
