A Head-To-Head Comparative Study of Covid-19 Patients Between Epicenter and Peripheral Areas of Pandemic From China

Background: There has been little information on difference of epidemiology, clinical characteristics and outcomes between epicenter and peripheral areas of Covid-19 pandemic. Methods: Based on Sichuan & Wuhan collaboration research group for Covid-19, we established two retrospective cohorts reflecting the epicenter and peripheral area of pandemic. Epidemiology, clinical characteristics and outcomes of patients were compared. Multivariate regression analyses were used to estimate adjusted odds ratios (aOR) to identify clinical variables associated with outcomes.Results: Upon March 12, 2020, Wuhan cohort consisted of 710 patients using random sampling, and 474 consecutive cases constituted Sichuan cohort. Sichuan cohort had more upper airway symptoms, while Wuhan cohort is elder, has more lower airway symptoms and comorbidities. Wuhan cohort had higher risk of death (aOR=7.64), ICU admission (aOR=1.66), delayed time from illness onset to hospital and ICU admission (aOR=6.29 and aOR=8.03) and prolonged duration of viral shedding (aOR=1.64). Conclusions: Worse outcomes in the epicenter would be explained by delayed time from illness onset to hospital and ICU admission associated with elevated systemic inflammation reflecting organ dysfunction and prolonged duration of virus shedding except for age and comorbidities. It indicates potentially clinical implications of Covid-19 that early supportive care would achieve better clinical outcome.
High-Purity Purification of 2,6-Dimethylnaphthalene (2,6-DMN) in Light Cycle Oil - Purification of 2,6-DMN from Concentrate of DMN Isomers by Crystallization -

The high-purity purification of 2,6-dimethylnaphthalene (2,6-DMN, 10.43 wt%) from the concentrate of DMN isomers recovered from light cycle oil (LCO) through distillation-extraction combination was examined by a crystallization operation. To select the most suitable crystallization solvent for purification of 2,6-DMN, several conventional solvents, which have been employed commercially as crystallization solvents for high-purity performance, were tested, through measurement of purity and yield of 2,6-DMN. The solvents used were acetone, cyclohexanone, ethanol, ethyl ether, ethyl acetate, isopropyl ether, methanol, n-hexane, n-heptane, pyridine, THF, toluene, and a mixture of methanol and acetone. The mixture of 60 vol% methanol and 40 vol% acetone (M/A = 1.5) was found to be suitable for purification of 2,6-DMN in the concentrate of DMN isomers based on purity and yield. Increasing the operation temperature and the volume ratio of solvent (M/A = 1.5) to feed (concentrate of DMN) resulted in improving the purity of 2,6-DMN, whereas the yield decreased. The crystal recovered by crystallization run using the concentrate of DMN isomers contained about 76 wt% 2,6-DMN. Furthermore, for recovery of high-purity 2,6-DMN, crystal containing 76 wt% 2,6-DMN was crystallized. As a result, crystal with 99.7 wt% 2,6-DMN was recovered with 40% yield.

Acceptance and Use of Mobile Technologies in Learning and Teaching of EFL: An Economic Perspective

The use and integration of mobile information and communication technologies (ICTs) in learning and teaching, as well as the creation of new knowledge can determine whether a country is able to successfully compete in the emerging global knowledge economy. Technology acceptance theories and models have been widely developed, used and extended to determine the factors related to the acceptance of such technologies in specific national and subject contexts. This study set out to explore the key factors that determine students’ and instructors’ use behaviour and behavioural intentions to use mobile technologies in learning and teaching EFL, in an effort to determine the readiness and acceptance of mobile learning and teaching among students and instructors at a higher education institution in Saudi Arabia. The extended Unified Theory of Acceptance and Use of Technology (UTAUT2), was used as the framework for this study. This model takes into account several perspectives; and was designed to assess technology acceptance beyond the organizational context by embedding consumer context dimensions. The results indicated that the research model was partially confirmed and highlighted key variables as the driving forces of use behaviour and behavioural intention to use mobile technologies in learning and teaching EFL.
Long term effect of different plant based nitrification inhibitors and calcium carbide on total soluble solids (TSS), ascorbic acid and protein content of cauliflower (Brassica oleracea var. Botrytis L)

The study was devoted to assess the effect of different nitrification plant based nitrification inhibitors and chemical inhibitor on total soluble solids (TSS), ascorbic acid and proteins content of cauliflower. The study was conducted as a field experimental with eight treatment combinations replicated thrice in completely randomized block design during rabi season 2018-19 and 2019-20. Different treatments combinations viz. melia fruit powder, pomegranate rind powder, commercial neem cake, calcium carbide (CaC2) and absolute control were incorporated in the study. The results revealed that during both the years of study maximum TSS values of 6.70 and 6.83 o brix were recorded in MF@ 20 g kg-1 soil and NC @ 20 g kg-1 soil, respectively. While the least TSS value recorded in control treatment. Maximum ascorbic acid was attributed to NC@ 20 g kg-1 soil i.e. 74.43 and 76.19 mg 100 g-1 during 2018-19 and 2019-20, respectively. Moreover, protein content in cauliflower varied from 2.44 g 100g-1 in control to 2.76 g 100g-1 in NC @20 g kg-1 soil during 2018-19 and 2.49 g 100g-1 in control to 2.76 g 100g-1 during 2019-20 in the same treatment. Application of plant based nitrification inhibitor neem cake@ 20 g kg-1 soil with recommended dose of NPK and farmyard manure was found effective over the chemical inhibitor and therefore improved the quality of cauliflower.
Inhibitory Effect of Nano-HA Particles on Human U87 Glioblastoma Cells Viability

To evaluate the effects of Hydroxyapatite nano-particles(nano-HA) with different morphologies on human U87 glioblastoma cell line(U87),three kinds of nano-HA were designed and synthesized,and a co-culture system containing nano-HA and U87 cells was established.Polyethylene glycol(PEG) was also added to the HA medium system for the samples stabilization.After determining the stabilization and high dispersed nanometer size of nano-HA in the medium system using Transmission electron microscope(TEM) and dynamic light scattering(DLS),the effects of nano-HA on GBM cells were assessed with an MTT method.Results showed that nano-HA could effectively inhibit U87 cells proliferation.Compared with other nano-HA,the needle-like nano-HA were more powerful in inhibiting U87 cells proliferation.Toll-like receptor 4(TLR4) induced by different nano-HA may be one reason for their different bioactivity.
Adaptive Trajectory Tracking During Motorized and FES-Induced Biceps Curls via Integral Concurrent Learning

A common rehabilitative technique for those with neuro-muscular disorders is functional electrical stimulation (FES) induced exercise such as FES-induced biceps curls. FES has been shown to have numerous health benefits, such as increased muscle mass and retraining of the nervous system. Closed-loop control of a motorized FES system presents numerous challenges since the system has nonlinear and uncertain dynamics and switching is required between motor and FES control, which is further complicated by the muscle having an uncertain control effectiveness. An additional complication of FES systems is that high gain feedback from traditional robust controllers can be uncomfortable to the participant. In this paper, data-based, opportunistic learning is achieved by implementing an integral concurrent learning (ICL) controller during a motorized and FES-induced biceps curl exercise. The ICL controller uses adaptive feedforward terms to augment the FES controller to reduce the required control input. A Lyapunov-based analysis is performed to ensure exponential trajectory tracking and opportunistic, exponential learning of the uncertain human and machine parameters. In addition to improved tracking performance and robustness, the potential of learning the specific dynamics of a person during a rehabilitative exercise could be clinically significant. Preliminary simulation results are provided and demonstrate an average position error of 0.14 ± 1.17 deg and an average velocity error of 0.004 ± 1.18 deg/s.
Ferromagnetism and spin-dependent transport at a complex oxide interface

Complex oxide interfaces are a promising platform for studying a wide array of correlated electron phenomena in low-dimensions, including magnetism and superconductivity. The microscopic origin of these phenomena in complex oxide interfaces remains an open question. Here we investigate for the first time the magnetic properties of semi-insulating NdTiO$_3$/SrTiO$_3$ (NTO/STO) interfaces and present the first milli-Kelvin study of NTO/STO. The magnetoresistance (MR) reveals signatures of local ferromagnetic order and of spin-dependent thermally-activated transport, which are described quantitatively by a simple phenomenological model. We discuss possible origins of the interfacial ferromagnetism. In addition, the MR also shows transient hysteretic features on a timescale of ~10-100 seconds. We demonstrate that these are consistent with an extrinsic magneto-thermal origin, which may have been misinterpreted in previous reports of magnetism in STO-based oxide interfaces. The existence of these two MR regimes (steady-state and transient) highlights the importance of time-dependent measurements for distinguishing signatures of ferromagnetism from other effects that can produce hysteresis at low temperatures.
Bottled Water from National Manufacturers in Somaliland: Water Quality and Health Implications

(1) Background: Somaliland, the breakaway republic of Northern Somalia, has a growing, commercial bottled water industry, but no available data on end-user water quality. The objective of this study was to do a public health quality assessment of popular brands of bottled water available in Somaliland. (2) Method: Between June and December 2010, 36 bottles with water from eight brands were purposefully sampled from shops in all four parts of Hargeisa city and analysed for 22 physico-chemical, five microbiological and nine informational variables. The findings were compared with international guidelines and the composition tables of the respective brands. (3) Results: The production and expiry dates on 50% of the bottles were inadequately presented. All of the physico-chemical measurements were within healthy limits; however, average pH was 5.6. Discrepancies between the physico-chemical analysis results and the composition table values provided on the bottles were large and significant (p = .018): Individual mineral concentrations could be as low as 1% of labelled values. Undesirable growth of total coliforms where found in 50% of all samples. (4) Conclusions: This study indicates a need for improved cleanliness in the production and distribution system, consistent production date labelling and regular physico-chemical analysis leading to accurate composition tables. There is a need for external monitoring of the quality of water delivered from the bottled water companies in Somaliland in order to prevent adverse public health effects.
Exploring the Gender Digital Divide in E-Government Use in a Developing Country

This article explores the gender digital divide in e-government use in Turkey. Historical trends and differences in internet and e-government use by males and females are investigated. The findings of this study indicate that although internet use has increased over the years, there remains a steady and significant gap between males and females in terms of internet use and e-government services use. It appears that females in Turkey tend to be on the wrong side of the digital divide, and a significant number of females do not benefit from the potential advantages of the internet and e-government services. The gender digital gap in e-government use is higher than in internet use.
Assessing Personality Traits and its influence on Academic Performance among Prospective Teachers of Shah Alam

Universities around the globe in this 21st century are facing challenges of globalization, technology and informational changes. Hence, to remain competitive and relevant, universities are required to equipped their students with new knowledge, skills and competencies so that they are able to cope with complex new roles which is in line with educational goals. Nonetheless, students have distinct personality traits which makes them perceived worldviews in a different way and behaving differently in various educational settings. Literature noted that non-cognitive constructs such as personality traits have been considered as predictors of success in learning. Thus, taking these differences into account can assist educators to recognize their students’ individual differences and academic achievement. Therefore, this study was intended to investigate personality traits and its influence on academic performance among prospective teachers of shah alam. A total of 130 prospective student teachers participated in this study. Pearson’s Product –Moment Correlation Coefficient (r) and multiple regression was conducted to measure the data. The finding showed that there was weak and positive relationships between conscientiousness and extroversion on academic performance. However, the finding found that the relationship between neuroticism and academic performance was significantly weak but inverse. Interesting, multiple regression analysis found that conscientiousness contribute about 11.8% of variance in academic performance. Implications and recommendation were discussed in this paper.

Histopathological Evaluation of Rabbit Hepatic Tissue Due to Remote Ischemic Reperfusion of Acute Limbs Injury Conducted with Ischemic Precondition and Hypothermic

Acute limb ischemia (ALI) is an emergency that occurs due to a rapid decrease in perfusion to limbs which can result in mitochondrial dysfunction, causing disturbances in distant organs such as liver. There are various ways to reduce the effects including treatment of hypothermia and ischemic preconditions. So, this study was made to see any differences in liver tissue damage as a result of reperfusion distant ischemic injury between the untreated and treated groups of hypothermia and ischemic precondition in cases of acute limb ischemia. This study is a true-experimental, with the New Zealand White (NZW) male rabbits as the samples and it divided into three groups, untreated rabbit group (as a control), treated with ischemic preconditioning group and hypothermia group. The data were collected by taking rabbit liver biopsy samples and were analyzed in univariate and bivariate with Shapiro Wilk normality test, independent T-test and Mann Whitney. This study used 21 rabbits as sample, 3 were excluded and each group have 6 samples. Statistical analysis of the comparison of liver tissue damage scores between the control group and the ischemic precondition treatment group showed a significant difference with a p value 0.002 and the comparison of the liver tissue damage scores between the control group and the hypothermic treatment group showed significant differences with p value 0.004. It can be concluded that there are liver tissue damage as a result of ischemic reperfusion injury in experimental rabbits, and there are significant differences in liver tissue damage between the control group, the hypothermia and ischemic precondition group

Στην παρούσα συγχρονική πeιραματική μeλέτη eρeυνήσαμe την πρώιμη ικανότητα των βρeφών να ανιχνeύουν διατροπικά την πληθικότητα οπτικο-ακουστικών αντικeιμένων και κοινωνικών eρeθισμάτων. Υποθέσαμe ότι η παρουσίαση του προσώπου θα αποσπούσe τη βρeφική προσοχή από την ανίχνeυση της αριθμητικής σταθeράς. Eξeτάστηκαν 78 βρέφη ηλικίας 5, 7 και 9 μηνών που συμμeτeίχαν σe τέσσeρις πeιραματικές Συνθήκeς (ταυτόχρονη προβολή ζeυγών όμοιων αντικeιμένων, ανόμοιων αντικeιμένων, αντικeιμένων ταυτόχρονα μe οικeίο πρόσωπο και αντικeιμένων ταυτόχρονα μe μη οικeίο πρόσωπο). Σe κάθe δοκιμή, τα ζeύγη των οπτικών eρeθισμάτων διέφeραν ως προς την πληθικότητα (1 – 2 / 1 – 3 / 2 – 3) και συνοδeύονταν από ήχους πιάνου ή φωνής της μητέρας ή μίας ξένης γυναίκας. Τα ακουστικά eρeθίσματα eπίσης διέφeραν ως προς το πλήθος (ένας, δύο ή τρeις ήχοι στην τονικότητα του La). Μέσω της τeχνικής του προτιμησιακού κοιτάγματος, μeτρήσαμe τη διάρκeια της βρeφικής προσοχής προς το οπτικό eρέθισμα που ταίριαζe αριθμητικά μe τον ήχο. Όταν προβάλλονταν αντικeίμeνα, τα βρέφη –eκτός από τα αγόρια 5 μηνών– έτeιναν να ανιχνeύουν δια-αισθητηρια- κά την αριθμητική σταθeρά. Η ομοιότητα του σχήματος των αντικeιμένων διeυκόλυνe τα βρέφη να αντιλαμβάνονται το κοινό πλήθος των οπτικο-ακουστικών eρeθισμάτων. Όταν προβάλλονταν το πρόσωπο μαζί μe αντικeίμeνα, τα βρέφη προτιμούσαν να κοιτούν προς το πρόσωπο, αγνοώντας το πλήθος του ακουστικού eρeθίσματος. Ούτe η ποιότητα του ήχου ούτe η οικeιότητα του προσώπου δeν eπηρέασαν τη βρeφική αντίληψη. Τα παραπάνω αποτeλέσματα υποδeικνύουν ότι, παρόλο που η διατροπική ανίχνeυση αντιληπτικών νύξeων eίναι μία πρωταρχική λeιτουργία τόσο της αντίληψης του προσώπου όσο και της αντίληψης του αριθμού, κάθe ένα από αυτά τα αντιληπτικά συστήματα φαίνeται να ακολουθeί ένα διαφορeτικό αναπτυξιακό μονοπάτι.
Nexus Between Tuberculosis and Diabetic Mellitus, A Prospective Cohort Study.

Background: This work aimed to describe the clinical presentation of TB in patient with DM, to determine the effects of DM on TB treatment outcomes, to identify the effects of TB on glycemic control, and to describe the lipid profile of TB and DM patients. Methods: This prospective cohort study design was conducted. The data were collected from September 2018 to June 2020 using patient interviews, examining the patients, chart review, and collecting blood samples. Binary logistic regression was used to identify the determinants of TB treatment outcomes in the context of DM. Kaplan Meier survival curve was used to see the effects of DM on TB clinical response. Linear regression was used to identify the determinants of the HbA1c level during TB infection. Results: A total of 1092 study participants were included giving for the response rate at 93.81 %. Good TB treatment outcome was observed in 72.5 % of the patients [95 % CI: 69 % - 76 %]. The odds of good TB treatment outcomes were at 75 % lower in the presence of DM (AOR 0.25 [95 % CI: 0.08 – 0.73]). The median time of clinical response in TB and DM patients was 45 days interquartile range (IQR) of 8 days; the median time of clinical response in DM free TB patients was 9 days [IQR 2 days]. TB increased the HbA1c level of DM patients by 1.22 % (B 1.22 [95% CI: 1.11 – 1.34]). In six months period, 60 % of TB and DM patients had got 3 episodes of acute complications. Conclusion: DM significantly decreases the favorable treatment outcome of DOTS. TB predisposed DM patients for bad glycemic control and increased episodes of acute DM complications.
Do Fans Impact Sports Outcomes? A COVID-19 Natural Experiment

This paper studies the effect of fan attendance on home field advantage in top European soccer leagues. We exploit exogenous variation in the level of fan attendance driven by COVID-19 mitigation policies and find that the home field advantage, as measured by home minus away (expected) goals, is reduced by more than 50% across the English Premier League, German Bundesliga, Italian Serie A, and Spanish La Liga. This leads to a decrease in probability for a home win, indicating that these goals are pivotal with respect to match outcomes.
The effects of low concentration methanol solutions on hydrate formation

The field experiments conducted by Statoil in collaboration with SINTEF (1) showed that hydrate blockages form more readily in under-inhibited systems than in systems completely without inhibitor. To further investigate this field observation, the Westport Technology Center conducted a set of hydrate formation experiments where hydrates were formed from aqueous solutions of 1.0 to 5wt% of methanol and natural gas. The results (2) showed that the rate of hydrate formation increases with increasing concentration of methanol in the water. Both gas up-take and reactor temperature showed substantial increase over those obtained from pure water.
