Published: June 2021

Abstract
In order to make full use of waste as raw materials to prepare low-cost zeolite, develop green chemical industry and achieve the purpose of treating waste with waste. High-purity zeolite X was prepared by the alkaline fusion hydrothermal method (AFH) using waste basalt powder as raw material, and was used as an adsorbent to investigate the adsorption performance for uranium-containing wastewater. The structure, morphology, specific surface area, chemical composition, chemical bonds, characteristic functional groups and chemical states of surface elements of the samples were characterized by XRD, SEM, BET, EDS, FT-IR and XPS. zeolite X with high crystallinity and rich hydroxyl/carboxyl groups was successfully synthesized by the AFH method, and its specific surface area was as high as 623.4 m2·g-1. When the adsorption time (t) is 720 min, the adsorption temperature (T) is 30 ℃, the initial uranium (VI) concentration is (C0) 35 mg/L, pH is 6.0, and the adsorbent dosage (m) is 5/35 mg/mL, the equilibriu adsorption capacity of zeolite X for uranyl ions is 228.4 mg·g-1. Thermodynamic results show that the adsorption process of uranyl ions by zeolite X is spontaneous and exothermic. Freundlich isotherms and quasi-second-order models are suitable to describe the adsorption process of uranyl ions by zeolite X. XPS analysis results show that -OH and -COOH play an important role in the adsorption process. At the same time, there is ion exchange between UO22+ and zeolite during the adsorption process.

Abstract
Background: Over the years, the issue of environmental degradation of ecological resources from crude oil pollution and its human health impacts is receiving more global attention. The utilization of environmental models capable of predicting the fate, transport and toxicity of chemicals in spilled crude oil can provide essential knowledge required to deal with the complexity associated with the fate of volatile petroleum chemicals in the environment. Objective: This paper explores environmental fate of toxic volatile organics from oil spill in the Niger Delta Region of Nigeria.Methods: A critical analysis of available literatures/data from PubMed, Scopus, ResearchGate, Google Scholar, Jstor, including expert working group reports and environmental modeling using a screening tool (USEPA EPI Suite™) was carried out to determine the environmental partitioning of Benzene, Toluene and Naphthalene (BTN) respectively. The organic-carbon partitioning coefficient (Koc) was computed as a function of soil-water distribution coefficient (Kd) and percentage organic matter (%OM). This was utilized to determine the distribution of BTN in the environment and the possible risk posed on delicate ecological resources from crude oil pollution due to exploration and production activities within the Niger Delta Region (NDR), Nigeria. Results: Results from literature implicated sabotage and operational failures from pipelines as primary causes of crude oil spillages. Generation of a fugacity model using EPI Suite™ revealed that the behavior of BTN is greatly influenced by Koc values. The default Molecular Connectivity Index (MCI) showed that benzene and toluene will partition more into the water compartment while naphthalene will partition into the soil compartment. However, user-entered values showed all three chemicals partitioning more into the soil compartment. Aquatic toxicology estimation using Ecological Structural Activity Relationship (ECOSAR) revealed all chemicals not to be toxic even at over-estimated Koc values. Conclusion: This research established the usefulness of screening level environmental modelling tools in assessing environmental risk and hence helpful in developing site-specific models for monitoring chemicals in the environment which can assist governments, policy makers and industries in the design of appropriate regional disaster management plans.

Abstract
Background: Multiple sclerosis (MS)is the most common neurological disease that causes disability in the nervous system which reduces the quality of life(QoL). Studies have shown positive effects of therapeutic exercise with supplementation on motor- and cognitive functionandfatigue as well as on QoLin persons with MS. The purpose of this study was to the effect of home-based aerobic training (AT) and vitamin D(Vit D) supplementation on fatigue and QoL in patients with MS during the covid-19 outbreak. Methods: We recruited 40 females (20 - 40 years) with MS(EDSS: 3-5). Then, using simple randomization, the subjects were assigned to four groups including aerobic training (AT; n=9; 50%-75%, 20-40 min/day, 3 days/wk aerobic training), vitamin D supplementation (Vit D; n=9; 50,000 IU one day/week), aerobic training plus vitamin D supplementation (AT + Vit D; n=10), and sedentary control (C; n=10 placebo). The data were analyzed using paired t-test and one-way analysis of variance and Tukey’s post hoc test with SPSS21 at a significance level of P < 0.05.Results: After eight weeks of intervention, fatigue grade markedly reduced in the AT + Vit D, AT, and Vit D groups); However, fatigue increased in the control group. QoLincreased significantly in AT+Vit D, AT, and Vit D compared to C. Also, the results show that the AT+Vit D had significantly higherQoL compared to AT and Vit D. Conclusion:These findings suggest that therapeutic AT and VitD supplementation is very effective in reducing fatigue and consequently improves the QoLin female MS patients.

Abstract
Background

Heart rate variability (HRV) reflects the balance of activities of sympathetic and parasympathetic components of the autonomic nervous system. Anti-thyroid antibodies have long been associated with thyroid dysfunction and influence thyroid profile testing, the most common being anti-Thyroid Peroxidase (TPO) and anti-Thyroglobulin antibodies. Subclinical hypothyroidism (SCHypo) is characterized by elevated TSH with normal thyroid hormones.We hypothesized that autonomic function may be deranged in anti-TPO positive sub-clinical hypothyroid cases even before the onset of overt hypothyroidism.
Objectives

To investigate the association between anti-TPO antibodies (anti-TPOAb) positive SCHypo and sympathovagal imbalance (SVI).
Methodology:

The study was conducted on age and BMI matched subclinical hypothyroid patients (n = 52) and healthy controls (n = 20). Cardiac autonomic activity was assessed by short term HRV in the time (SDNN, RMSSD, pNN50) and frequency domain (LFms2, HFms2, LFnu, HFnu, TP and LF/HF ratio). Nonlinear geometric measures (SD1, SD2, SD1/SD2, TINN, HRV triangular index) were also evaluated. Biochemical evaluation of serum thyroid profile, anti-TPOAb was done in all the subjects.
Results

Decreased HRV was observed in anti-TPOAb positive group when compared to negative and control groups. Significant positive correlation of anti-TPOAb with TSH, LF nu, LF/HF and negative correlation with SDNN, RMSSD, pNN50, SD1, SD1/SD2, HFnu and TP of HRV was observed.
Conclusion

Anti-TPOAb positive SCHypo group exhibited modifications in HRV characterized by decreased parasympathetic modulation, as compared to controls. The findings were also suggestive of increased risk of autonomic dysfunction in TPOAb- positive patients than negative. Anti-TPO antibody was significantly correlated with TSH and SVI in SCHypo patients.

Abstract
Antimicrobial resistance (AMR) is considered a global threat, and novel drug discovery needs to be complemented with systematic and standardized epidemiological surveillance. Surveillance data are currently generated using phenotypic characterization. However, due to poor scalability, this approach does little for true epidemiological investigations. There is a strong case for whole-genome sequencing (WGS) to enhance the phenotypic data. To establish global AMR surveillance using WGS, we developed a laboratory implementation approach that we applied within the NIHR Global Health Research Unit (GHRU) on Genomic Surveillance of Antimicrobial Resistance. In this paper, we outline the laboratory implementation at four units, in Colombia, India, Nigeria, and the Philippines. The journey to embedding WGS capacity was split into four phases: Assessment, Assembly, Optimization, and Reassessment. We show that onboarding WGS capabilities can greatly enhance the real-time processing power within regional and national AMR surveillance initiatives, despite the high initial investment in laboratory infrastructure and maintenance. Countries looking to introduce WGS as a surveillance tool could begin by sequencing select Global Antimicrobial Resistance Surveillance System (GLASS) priority pathogens that can demonstrate the standardization and impact genome sequencing has in tackling AMR.

Published: June 2021

Abstract
Background: To compare the effectiveness of High Flow Nasal Cannula (HFNC) and standard non rebreathing mask (NRBM) as oxygen delivery device, in moderate cases of COVID-19 Pneumonia.Methods: A single-centre, prospective, open label randomized controlled trial was conducted between February 2021 and April 2021. Sixty enrolled patients were randomly divided into two groups according to the oxygen delivery device used. Group 1 (n = 30) received HFNC and group 2 (n = 30) received NRBM as initial oxygen delivery device, to maintain a target saturation of ≥ 96% in both groups. The success rate of oxygen therapy, time to progression to severe disease, PaO2, PaO2/FiO2 ratio, respiratory rate, heart rate, blood pressure, number of patients requiring NIV or endotracheal intubation, time for de-escalation of oxygen therapy to lower Fio2 device and patient satisfaction level were compared among the two groups.Results: Demographic, clinical variables and treatment given were comparable in the two groups. In the HFNC group 83.3% patients had successful outcomes with the initial oxygen therapy device used as compared to 66.6% in the NRBM group. However, the use of HFNC resulted in improved oxygenation (P < 0.001), better patient satisfaction (P < 0.001) and shorter time for de-escalation of oxygen therapy to a lower FIO2 device (3.75 ± 1.032 vs. 6.83 ± 0.928).Conclusions: HFNC is a reliable oxygen therapy modality for moderate category COVID-19 pneumonia that results in better oxygenation and a greater patient satisfaction level as compared to a non-rebreathing mask.Trial Registration: ctri.nic.in; Reg No: CTRI/2021/01/030829; Date of Reg: 05/02/2021
Scientifically Speaking We know a lot, or do we? A model of knowledge using the Electromagnetic Spectrum
Authors: Espinoza Fernando 
Published: June 2021

Abstract
A quantitative model of human knowledge of the physical world based on the use of various parts of the electromagnetic spectrum is proposed. The model is epistemologically effective in demonstrating limits to what scientific knowledge can provide us about the physical world, thus enhancing for students the potentially exploratory opportunities available in scientific research, based on how little we really know. Additionally, the model provides a pedagogically useful way to engage students in considerations of the role of measurement, scale and estimation; these features are urgently needed by many students according to international assessments and are particularly important for non-science majors.

Authors: Mahdy Mohamed A. A. 
Published: June 2021

Abstract
Purpose: The present study assessed the shift to remote teaching of veterinary anatomy during the COVID‐19 pandemic based on students’ perspectives. Methods: Participants were invited to answer an anonymous online Google Form questionnaire using the snowball sampling method. Only students who studied anatomy online during the COVID-19 lockdown period were eligible to answer the questionnaire. Results: A total of 961 participants were enrolled in this study from 87 countries and 6 continents. Data showed that the majority of students (81.6%) were interested in studying anatomy online during COVID-19 lockdown. Moreover, approximately 82% of students were comfortable with the technological skills and approximately 61% of students can understand online anatomy well during lockdown. Furthermore, approximately 52.76% of students believed that online learning of anatomy suited for theoretical, 8.74% believed that it suited for practical parts, and 30.28% believed that it suited for both theoretical and practical parts. On the contrary, about 36.63% of students thought that online learning of anatomy could replace face-to-face teaching. In conclusion, shifting to remote teaching appears to be a good and convenient approach during the lockdown period as shown by student interest to study anatomy online during the COVID-19 lockdown, their comfortability with the technological skills, and their level of understanding. However, practical classes with cadaver dissection and dealing with different anatomical specimens is essential for veterinary students, therefore, blended learning is recommended. Conclusion: the study highlighted several challenges associated with studying anatomy online during lockdown period and recommendation to overcome these challenges.

Abstract
Background: In malalignment syndrome, the spino-pelvic alignment correction with foot orthotics can be applied only to a standing position in the coronal plane. Considering the fact that the average time Koreans spend sitting in a chair is 7.5 hours per day, studies on spino-pelvic correction in sitting position is needed. The purpose of this study is to investigate the pressure changes and radiographic assessment of spino-pelvic alignment using a chair equipped with a height-adjustable seat-plate.Methods: Experiments were conducted on 30 research participants. The inclusion criteria for the participants were as follows: The volunteers of nonstructural malignment syndrome with shoulder height differences (SHDs) or iliac flea height differences (ICHDs) greater than 5 mm in radiographic images excluding participants with structural deformity. All participants were subjected to measure buttocks interface pressure while seated using a smart chair in three consecutive steps: (1) on initial seated, (2) on balancing seated, and then (3) on 1hr balancing seated. Radiographically, the five spino-pelvic parameters such as SHD, ICHD, LLD, POA, and coronal imbalance were analyzed to investigate the effect of pelvic imbalance compensation on spino-pelvic alignment.Results: Pelvic imbalance was compensated with seat plate height adjustment in average of 3.6 ± 1.8 mm, so that the pressure discrepancy improvement between buttocks from 36.4 ± 32.3 on initial seated to 15.7 ± 20.3 on balancing, 12.7 ± 10.9 on 1hr balancing seated (Ω, p=0.008). The radiographic changes before and after pelvic imbalance compensation demonstrated a statistically significant improvements of spino-pelvic parameters on sitting and standing: at the average value of -0.9 to -0.8 and 9.5 to 2.5, SHD and ICHD, respectively (mm, p=0.005, 0.037) and -3.0 to -1.0, 1.8 to 0.8, and 0.8 to 0.1, SHD, ICHD, and LLD, respectively (mm, p=0.005, 0.016, 0.033).Conclusions: Spino-pelvic malalignment can be improved by individually customized pelvic compensation using balanced seat plate height adjustments under the real-time pressure sensing and monitoring on the buttocks while seated.

Abstract
The quality and reliability of electric power supply systems determine the quality of life and the growth of a nation. Electricity is present in every aspect of our daily lives. Renewable energy is, without a doubt, one of the most critical drivers of a country's socio-economic growth, and its importance in this regard cannot be overstated. Electricity access plays a significant role in other sources of energy. Electricity has made life much more straightforward in various sectors and facets of human endeavors, such as education, health, agriculture, and all households. Efficient power consumption and energy savings have become a major issue these days as the need for power demand increases day to day in Ethiopia. Ethiopia’s electricity coverage and per capita consumption are among the lowest in sub-Saharan Africa. Only 44 percent of over 110 million Ethiopians have access to electricity. Around 83% of the population lives in areas with less than 2% of the population having access to electricity. Electricity is a necessary component of any modern economy. A country's economic growth and development are dependent on the availability of a sufficient power supply at a fair cost. However, to meet the demand and minimize greenhouse gas emissions, cost-effectiveness and efficiency in electricity generation and distribution must be improved further.
