Published: July 2021

The purpose of work is to evaluate the 4-chlorophenol (CP) adsorption capacity of brown coal activated carbons (ACs) prepared at different temperature of KOH activation. ACs were obtained in three stages: 1) impregnation of coal with a KOH solution, 2) heating (4 deg/min) in argon to a given temperature t (400-800°C) and exposure for 1 h, 3) cooling, washing from KOH, drying. The samples are designated as AC(t). Based on the N2 adsorption-desorption isotherms, the ACs total pore volume (Vt, cm3/g) and specific surface area (S, m2/g) were determined. The ACs adsorption capacity were measured at 25°С, CP concentration ≤700 mg/L, АC dosage – 1 g/L.
The alkaline activation temperature was found to be a key factor in forming porosity of ACs and ability to adsorb CP. The CP maximum capacity (ACP(m), mg/g) increases 6.6 times up to 307 mg/g for AC(800) having S=1142 m2/g. The specific adsorption capacity (ACP(S) = ACP(m)/S, mg/m2) sharply decreases in a sample range from AC(400) to AC(550) and weakly depends on temperature at 550-800°C. The kinetics of CP adsorption is best described by a pseudo-second order model. The rate determining stage is the interaction of CP molecules with AC surface. The CP adsorption isotherms are best described by the Langmuir model.
The dependence of the ACP(m) from S can be approximated by three linear equations that probably correspond to the three regions of forming surface adsorbtion centers (AdCs). The first (S≤370 m2/g) is characterized by a small adsorption capacity increment (kS=0.103 mg/m2), but a significant (16.4 times) decrease in the specific capacity ACP(S). In the second region (S=370-770 m2/g, t=550-750°C), capacity increment is 10 times more (kS=0.985 mg/m2) and in the third region (S≥770 m2/g, t≥750°C) the increase in CP capacity is the smallest (kS=0.067 mg/m2). The thermoinitiated formation of AdCs is assumed to be not proportional to the increase in surface area, and their chemical structure and reactivity is determined by the alkaline activation temperature.

Case:
Our patient was a 31-year-old woman with previously undiagnosed panhypopituitarism who presented with bilateral slipped capital femoral epiphysis (SCFE). Together with endocrinology, her treatment plan involved medical management of her panhypopituitarism and surgical correction with femoral neck osteotomy. Hormone deficiencies were corrected 6 weeks after replacement therapy began, and the patient was cleared for surgery. By 5 months after osteotomy, examination revealed delayed union and prominent screws bilaterally. Hardware exchange and repeat internal fixation were then performed. At 8 weeks after revision, she presented with avascular necrosis, and the decision was made to proceed with total hip arthroplasty. A 5-year follow-up period was documented.

Conclusion:
This case presented a rare look at SCFE in an adult patient with panhypopituitarism. Other systemic illnesses that can contribute to SCFE or other orthopaedic issues include, but are not limited to, multiple endocrine neoplasia syndromes, vitamin D deficiency, renal osteodystrophy, Kallmann syndrome, Klinefelter syndrome, and pathologies affecting the thyroid and pituitary gland.

Abstract
Background A new coronavirus, SARS-CoV-2, has caused the coronavirus disease-2019 (COVID-19) epidemic. Current diagnostic methods mainly include nucleic acid detection, antibody detection, antigen detection, and chest computed tomography (CT) imaging. Although these methods are crucial for the diagnosis of COVID-19, there is a lack of a rapid and economical method for preliminary screening COVID-19.Methods We measured the FeNO concentrations of 103 subjects without COVID-19 and 46 patients with COVID-19. Using machine learning (ML) method, we build a ML model based on fractional exhaled nitric oxide (FeNO) concentration and features of age, and body size for rapid preliminary screening COVID-19 suspects with low-cost.Findings The statistical analysis t-test show that there is a significant difference between the FeNO of healthy people and patients with COVID-19. The ML model can screen out the patients with COVID-19 or other diseases, which show abnormal FeNO distributions. An area under the curve of 0.982 and a sensitivity 0.917 have been achieved for preliminary screening COVID-19 suspects. This non-invasive detection method which takes in two minutes and costs less than a dollar could provide a direction for the control of the rapid spread COVID-19.Interpretation During the COVID-19 pandemic, large numbers and extensive testing of COVID-19 patients remains a problem. Public healthy efforts to limit SARS-CoV-2 spread need to find a more economical and faster screening method.

Published: July 2021

Abstract
The Arnasay depression in Central Uzbekistan received large quantities of drainage water leading to the formation of the Aydarkul-Arnasay Lake System (AALS). The water level of the AALS drastically increased in 1969, when a flood in the nearby Syrdarya River basin could not be contained in the Chardarya reservoir, and today it occupies an area of 4000 km² of the Mirzachul and Kyzylkum desert. Increasing the lake’s water level also affects the surrounding agricultural land, further enhancing the level of groundwater and soil salinization. But the irrigated farming areas also influence the lake system due to the pollution of the drainage water discharged into the lake. As a result, both the arable land and the lake system are in a process of degradation, leading to reduced productivity and a variety of ecological problems. We used more of the remote sensing method in determining the degradation process in agroirrigation landscapes. Landsat EVI (Enhanced vegetation index) extremely resistant to various atmospheric resistances (aerosols). It monitors plants with very high sensitivity even in low biomass areas. Landsat has 4,5,7,8 series programs. Herein, we used Landsat-5 TM Collection 1 Tier 1 32-Day EVI and Landsat-8 ETM + Collection 1 Tier 1 32-Day EVI. To classify the degradation process in agroirrigation landscapes around the lake, we compared Landsat EVI images from March-April, May-June, June-July, Ilyul-August, August-September. We selected July-August as the optimal month to determine the perennial degradation process.

Abstract
In this paper a simple and tunable reflective polarization converter has been investigated numerically based on metamaterial which composes of a two-corner-cut square patch resonator with a slit embedded into Vanadium dioxide film (VO2) and reflective ground layer. All the results obtained by the CST Microwave Studio show that the polarization conversion ratio (PCR) above 90% is achieved from 2.22-5.42THz at the temperature about 25°C under the linearly and circularly polarized wave incidence normally. In addition, the influences on electromagnetic polarization properties have been demonstrated with the insulator-to-metal phase transition of the Vanadium dioxide film (VO2) film by the method of varying the temperature. At the same time, to be demonstrated, the physical mechanism of changeable polarization conversion has been discussed by the distributions of current densities. According to the results, the designed metamaterial could be applied in the area of temperature-controlled sensing, THz wireless communication, tunable polarized devices.

Published: July 2021

Abstract
This study demonstrates and analyses spatio-temporal changes and trends of 15 water quality parameters that were arbitrated from the samples collected at 11 sampling locations during the water quality monitoring across the Dal Lake from September 2017 to August 2020. Further a revised WQI (named WQImin) was developed contingent on multiple regression modeling comprising six key parameters (NH4-N, DO, COD, WT, TUB and NO3-N) so as to ease the course of action and lessen the systematic costs of the water quality assessment. The results signify that the general mean WQI value 81.9 and seasonal average WQI values ranges from 79.44 to 84.55. The quality of water showed seasonal variance, with lowest values in summer, succeeded by autumn and winter, and highest in spring. Moreover, the suggested WQImin model contingent on the selected six critical parameters displayed execution in the evaluation of Dal Lake’s water quality with R2 = 0.99, RMSE value (5.48) and PE value of 6.34%. This manifested that the developed WQImin model can be convenient and efficacious implement to control and determine Dal Lake’s water quality. Further results showed that most of the nutrients were above the threshold value during the monitoring period, which is the leading cause of eutrophication at some places in the lake.

Abstract
The current study was carried out near and surrounding fault line areas of Balakot-Bagh (B-B). The study aimed to find radon concentration levels in drinking water sources near and away from the fault line. The comparison was carried out for the radon level in those samples taken from the area near with those taken away from the fault line. Also, to evaluate health hazard from these drinking water to the people of the area. This area had received an earthquake of magnitude 7.6 in 2005. An active technique, RAD-7, based on alpha spectroscopy was used. The study period for the current study was three months, from 16th May to 15th August 2020. Radon concentrations were found higher in bore water with the mean value of 20.6 BqL− 1. These were 19.5 BqL− 1 and 9.3 BqL− 1 in spring and surface water, respectively. The mean value in all type of sources in the study area was 16.5 BqL− 1 which is higher than the maximum contaminated level of 11.1 BqL− 1 recommended by the U.S. The calculated doses from the radon levels were 0.0532 mSv, 0.0562 mSv and 0.0254 mSv and 0.0449 mSv, respectively.
Past Gait Speed as an Independent Predictor of Mortality in Older Adults Beyond Current Gait Speed
Authors: Solomon Joshua , Chabot Julia , Desmarais Philippe , Forget Marie-France , Nguyen Quoc Dinh 
Published: July 2021

Abstract
Background
We investigated whether past values of gait speed in older adults provide additional prognostic information beyond current gait speed alone. We assessed various models to best describe past and current value for prediction.
Methods
We used data from the first five yearly rounds of the National Health and Ageing Trends Study, starting from 2011. The cohort consisted of 4289 community-dwelling participants aged 65 years and older. Gait speed was measured at baseline (Y1) and one year later (Y2). Three-year follow-up for mortality started in year 2. We estimated hazard ratios of various models using combinations of Y1 gait speed, Y2 gait speed, and change in gait speed from Y1 to Y2.
Results
The mean gait speed at year 2 was 0.77 m/s (0.26) and slightly increased by a mean of 0.04 m/s (0.20) from Y1 to Y2. A 0.1 m/s higher gait speed at Y2 was associated with decreased mortality (HR, 0.81 [0.78, 0.84]). Gait speed improvement from Y1 to Y2 decreased mortality (HR, 0.95 [0.92, 0.99] per 0.1 m/s increase). Models including both Y2 gait speed and change indicated that improvement in gait speed was associated with increased mortality (HR, 1.05 [1.00, 1.11]), independently of Y1 gait speed.
Conclusions
Past gait speed is predictive of mortality, independent of current gait speed, however, gait speed recovery does not completely negate mortality risks. Past gait speed information is a useful measure for risk prediction in older adults, but the direction of time is important for modelling and data interpretation.
A Case Study From Ramannapeta Mandal, Nalgonda, Telangana, India: Fluoride Contamination of Ground Water
Authors: Ganaboina G.Machender , Kota Narsimha 
Published: July 2021

Abstract
The groundwater quality evaluation for fluoride element was studied in Ramannapeta Mandal, Nalgonda District, and Telangana State, India. The water samples were collected in pre and post monsoon seasons in the year of 2015-2016 from hand pumps bore wells or dug wells in the villages of Ramannapeta Mandal. The collected water samples were analyzed within a week. The Spatial distributions of fluoride maps were prepared with the help of the Remote Sensing Imaginary (RSI) and Geographical Information System (GIS) techniques. The range of fluoride in the study area varied from 0.6 to 5.6 ppm whereas the maximum permissible limit in drinking water is 1.5 ppm (As per Bureau of Indian Standard (BIS) guideline-IS: 10500: 1991). The high contamination 4.0-5.5 ppm of fluoride in drinking water was observed in Siripuram, Dubbaka villages. During the study, it was found that the most of villages in Ramannapeta Mandal are affected with high fluoride content in drinking water in the range of 1.5-3.0 ppm. Nalgonda district including Ramannapeta Mandal is underlain by different rocks such as granites (80%), gneisses, dolerite, dykes (10%), older metamorphic and intrusive (10%). The lock of freshwater exchange due to periodical drought conditions, the granitic rocks and the arid climate of the region are the factors for the higher incidence of fluoride in the groundwater resources. The constructions of rain water harvesting structures are proposed to minimize fluoride content in drinking water.

Published: July 2021

Abstract
Background: Play is critical for children’s physical, cognitive, and social development. Technology-based toys like robots are especially of interest to children. This pilot study explores the affordances of the play area provided by developmentally appropriate toys and a mobile socially assistive robot (SAR). The objective of this study is to assess the role of the SAR on physical activity, play behavior, and toy-use behavior of children during free play. Methods: Six children (5 females, Mage = 3.6 ± 1.9 years) participated in the majority of our pilot study’s seven 30-minute-long weekly play sessions (4 baseline and 3 intervention). During baseline sessions, the SAR was powered off. During intervention sessions, the SAR was teleoperated to move in the play area and offered rewards of lights, sounds, and bubbles to children. Thirty-minute videos of the play sessions were annotated using a momentary time sampling observation system. Mean percentage of time spent in behaviors of interest in baseline and intervention sessions were calculated. Paired-Wilcoxon signed rank tests were conducted to assess differences between baseline and intervention sessions. Results: There was a significant increase in children’s standing (~15%; Z = -2.09; p = 0.037) and a tendency for less time sitting (~19%; Z = -1.89; p = 0.059) in the intervention phase as compared to the baseline phase. There was also a significant decrease (~4.5%, Z = -2.70; p = 0.007) in peer interaction play and a tendency for greater (~4.5%, Z = -1.89; p = 0.059) interaction with adults in the intervention phase as compared to the baseline phase. There was a significant increase in children’s interaction with the robot (~11.5%, Z = -2.52; p = 0.012) in the intervention phase as compared to the baseline phase. Conclusions: These results may indicate that a mobile SAR provides affordances through rewards that elicit children’s interaction with the SAR and more time standing in free play. This pilot study lays a foundation for exploring the role of SARs in inclusive play environments for children with and without mobility disabilities in real-world settings like day-care centers and preschools.

Published: July 2021

Abstract
Objectives To comprehend the epigenetic mechanism of low temperature in delaying senescence of fruit, the changes of DNA methylation patterns of genes related to ethylene biosynthesis and signaling were analyzed in tomato fruit. Results In the present results, the expression level of LeEIN3, SlERF-A1 and LeERT10 decreased, and the expression level of LeCTR1 increased in tomato fruit stored at the low temperature of 11 oC. Meanwhile, the DNA methylation level of CpG island of LeEIN3, SlERF-A1 and LeERT10 increased, and the DNA methylation level of CpG island of LeCTR1 decreased in tomato fruit, respectively. The low temperature suppressed ethylene signaling via changing DNA methylation and gene expression, and delayed senescence of tomato fruit. Conclusions The present study offered valuable information for understanding the role of DNA methylation in senescence of fruit, and provided a foundation for genetic modifying the epigenetic target sites and controlling fruit senescence.

Abstract
Background: Workplace programmes to test staff for asymptomatic COVID-19 infection have become common, but raise a number of ethical challenges. In this article, we report the findings of a consultation that informed the development of an ethical framework for organisational decision-making about such programmes.Methods: We conducted a mixed-method consultation – a survey and semi-structured interviews – in a case study organisation that had introduced asymptomatic testing for all staff working on-site in its buildings. Analysis of closed-end survey data was conducted descriptively. An analysis approach based on the Framework Method was used for the open-end survey responses and interview data. The analyses were then integrated to facilitate systematic analysis across themes. Inferences were based on the integrated findings and other inputs (literature review, ethical analysis, legal and public health guidance, expert discussions) to develop an ethical framework. Results: The consultation involved 61 staff members from the case study organisation (50 survey respondents and 11 interview participants). There was strong support for the asymptomatic testing programme: 90% of the survey respondents viewed it as helpful or very helpful. Open-ended survey responses and interviews gave insight into participants’ concerns, including those relating to goal drift, risk of false negatives, and potential negative impacts for household members and people whose roles lacked contractual and financial stability. Integration of the consultation findings and the other inputs identified the importance of a whole-system approach with appropriate support for the key control measure of isolation following positive tests. The need to build trust in the testing programme, for example through effective communication from leaders, was also emphasised.Conclusions: This consultation, together with other inputs, informed an ethical framework intended to support employers. The framework may support organisational decision-making in areas ranging from design and operation of the programme through to choices about participation. The framework is likely to benefit from further consultation and refinement in new settings.
