One step synthesis of maltose functionalized red fluorescent Ag cluster for specific glycoprotein detection and cellular imaging probe

The synthesis of non-cadmium based carbohydrate functionalized inorganic fluorescent nanoparticles has emerging potential applications in advanced biomedical science. Herein, we synthesized red fluorescent maltose functionalized silver clusters (AgC) using cysteamine modified maltose as a capping agent without adding any external reductant. The silver clusters had a hydrodynamic diameter of less than 5 nm with good colloidal, photochemical and fluorescent stability with a reasonably good fluorescence quantum yield. Maltose functionalized fluorescent silver clusters were produced in a one step procedure. Therefore, we exploited the maltose functionalized silver clusters for the visible detection of specific glycoprotein concanavalin-A. Because the synthesized red fluorescent maltose functionalized silver clusters possesses good photochemical stability and green light excitation, we used maltose functionalized red fluorescent AgC for HeLa cell labelling study.
Effects of Counter Ions (SO42 – and Cl– ) on the Adsorption of Copper and Nickel Ions by Swollen Chitosan Beads

swollen spherical beads of2.5 mmin average diameter, and with an average water content of 92%(wt/wt). The beads were collected and washed thoroughly with distilled water. High-grade CuSO4 à" 5H2O, CuCl2 à" 2H2O, NiSO4 à" 7H2O and NiCl2 à"6H2Osalts were used as adsorbates. Two grams of wet chitosan beads and 38ml ofa liquid solution of the prescribed concentration of an adsorbate were placed in a 100ml flask fitted with a stopper. The flask was shaken in a water bath maintained at 30+0.5°C for 24 hr, with shaking at 150 per minute in the longitudinal direction and 75 per minute in the transverse direction. After shaking, the solution was centrifuged at 6,000 rpm for lOmin. The residual concentration of metal ions in the supernatant was measured by atomic absorption spectrophotometry (Seiko SAS727). The adsorbed amounts of copper and nickel were calculated from their residual concentrations in the supernatant. The pH of the solution was not controlled because the addition of a buffer solution could disturb the net function of counter ions for metal adsorption. Therefore, all
Macroporous Bismuth Film Screen‐Printed Carbon Electrode for Simultaneous Determination of Ni(II) and Co(II)

Macroporous bismuth film screen-printed carbon electrode (mpBiF-SPCE) was used for simultaneous measurement of Ni(II) and Co(II) at their trace concentration level by means of adsorptive cathodic stripping voltammetry with dimethylglyoxime as a complexing agent. The mpBiF-SPCE was prepared on a screen printed carbon electrode by colloidal crystal templating using aqueous suspension of polystyrene microspheres which were self-assembled onto the electrode by slow evaporation of solvent. Following the electrochemical deposition of bismuth film, the microspheres were dissolved with toluene providing the macroporous bismuth film structure. The mpBiF-SPCE offered good electroanalytical performance with estimated limits of detection of 27 and 94 ng L−1 for Ni(II) and Co(II), respectively, in combination with an accumulation time of 180 s, and relative standard deviations of 3.3 % for Ni(II) and 5.2 % for Co(II). The effect of potentially interfering ions and the surface-active compounds was also investigated. Both Ni(II) and Co(II) were assayed in the sample of sewer water with satisfactory recovery.

What matters when managing childhood fever in the emergency department? A discrete-choice experiment comparing the preferences of parents and healthcare professionals in the United Kingdom. AUTHORS

Background Fever among children is a leading cause of Emergency Department (ED) attendance and a diagnostic conundrum; yet robust quantitative evidence regarding the preferences of parents and healthcare providers (HCPs) for managing fever is scarce. Objective To determine parental and HCP preferences for the management of paediatric febrile illness in the ED. Setting Ten children’s centres and a children’s ED in England from June-2018 to January-2019 Participants 98 Parents of children aged 0-11 years, and 99 HCPs took part. Methods Nine focus-groups and coin-ranking exercises were conducted with parents, and a discrete-choice experiment (DCE) was conducted with both parents and HCPs, which asked respondents to choose their preferred option of several hypothetical management scenarios for paediatric febrile illness, with differing levels of; visit time, out-of-pocket costs, antibiotic prescribing, HCP grade and pain/discomfort from investigations. Results The mean focus-group size was 4.4 participants (range 3-7), with a mean duration of 27.4 minutes (range 18-46minutes). Response rates to the DCE among parents and HCPs were 94.2% and 98.2% respectively. Avoiding pain from diagnostics, receiving a faster diagnosis and minimising wait times were major concerns for both parents and HCPs, with parents willing-to-pay £16.89 for every one-hour reduction in waiting times. Both groups preferred treatment by consultants and nurse practitioners to treatment by doctors in postgraduate training. Parents were willing to trade-off considerable increases in waiting times (24.1mins) to be seen by consultants and to avoid additional pain from diagnostics (45.6mins). Reducing antibiotic prescribing was important to HCPs but not parents. Conclusions Both parents and HCPs care strongly about reducing visit time, avoiding pain from invasive investigations and receiving diagnostic insights faster when managing paediatric febrile illness. As such, overdue advances in diagnostic capabilities should improve child and carer experience and HCP satisfaction considerably in managing paediatric febrile illness.

Perception of and Satisfaction with Video Assistant Refereeing in Soccer

The recent introduction of Video Assistant Referee (VAR) in soccer yielded mixed responses from soccer enthusiasts. This study primarily aimed at determining how much variance in satisfaction with VAR could be explained by the perceptions thereof. The secondary aim was to determine the effect of selected demographic variables on perception and satisfaction with VAR in a South African sample. A cross-sectional quantitative survey entailing a non-probability sample consisting of 140 (n = 140) respondents was used to measure perception and satisfaction with VAR at soccer matches. Inferential statistical analyses were performed viz. multiple regression analysis, independent sample t-tests and MANOVA to analyse the dataset. Results indicated that perception of VAR statistically significantly predicted satisfaction with the stated. It was determined that 22.2% of the variance in satisfaction with Video Assistant Refereeing could be attributed to the perception thereof. Additionally, as perception increased there was a concurrent increase in satisfaction with VAR. Results relating to the demographic variables and the impact thereof on perception of and satisfaction with VAR yielded mixed results. The application of VAR, in conclusion, has to be improved considerably for it to placate soccer enthusiasts as evident from the results presented.
Costus Root Extract Preserves Thyroid Hormones Levels, Thyroglobulin Expression and Thyroid Tissues in Rats Receiving Valproate Sodium

BACKGROUND: Valproate sodium is an anticonvulsant drug. Saussurea lappa (costus) is a medicinal plant rich with antioxidants. This research aimed to assess the protective effect of costus root extract against valproate sodium-induced thyrotoxicity. METHODS: Eighty adult male albino rats were equally divided into four groups; group I: untreated control, group II: rats were given 200 mg/kg BW valproate sodium orally and daily for 8 weeks, group III: rats were given 300 mg/kg BW costus root extract orally and daily for 8 weeks, and group IV: rats were given combination of valproate sodium and costus root extract. After 8 weeks, blood samples were collected to evaluate T3, T4 and thyroid-stimulating hormone (TSH) levels. Thyroid gland samples were handled for light and electron microscopic investigation. The heights of follicular cells, area % of collagen fibers and color intensity of thyroglobulin immunoreaction were statistically analyzed. RESULTS: After being given valproate sodium as an induction, hormonal assay showed significant decrease in serum T3 and T4 and significant increase of TSH. Follicular and cellular alterations were shown by light and electron microscopes. Morphometric study revealed increased follicular cell height and area % of collagen fibers and decreased color intensity of thyroglobulin. In contrast, costus root extract appeared to have a protective role against valproate sodium-induced thyroid injury. Most of the changes induced by valproate sodium were not observed after supplementation with the plant root extract. CONCLUSION: Valproate sodium has serious effects on the function and structure of thyroid gland, and this study shows that costus root extract could have a protective effect against these effects. KEYWORDS: valproate sodium, rat, thyrotoxicity, Saussurea lappa
Effect of hydrogen addition to fluorocarbon gases (CF4, C4F8) in selective SiO2/Si etching by electron cyclotron resonance plasma

We investigated the etch rate of SiO2 and Si in an electron cyclotron resonance (ECR) etching system as a function of H2 adding percentage to fluorocarbon gases such as CF4 and C4F8. The selectivity increases considerably in the case of C4F8 plasma as the H2 percentage increases. Actinometric optical emission spectroscopy and appearance mass spectrometry were employed to elucidate the mechanism of selective SiO2/Si etching in ECR plasma and the following are confirmed. First, the relative behavior of CF2 radical density as a function of H2 percentage in a CF4 ECR plasma system is very similar to that in a rf capacitively coupled plasma (RFCCP) system but its increasing rate with the addition of H2 is smaller by an order of magnitude compared to the case of CF4 RFCCP system. Second, the dominant polymer precursors that are responsible for the selective SiO2 to Si etching is CF among CFx (x=1–3) radicals in C4F8+H2 ECR plasma and the decreasing rate of the relative concentration of atomic F is higher in CF4.
Pattern transfer of hydrogen depassivation lithography patterns into silicon with atomically traceable placement and size control

Reducing the scale of etched nanostructures below the 10 nm range eventually will require an atomic scale understanding of the masks being used in order to maintain exquisite control over both feature size and feature density. Here, the authors demonstrate a method for tracking atomically resolved and controlled structures from initial template definition through final nanostructure metrology, opening up a pathway for top–down atomic control over nanofabrication. First, hydrogen depassivation lithography is performed on hydrogen terminated Si(100) using a scanning tunneling microscope, which spatially defined chemically reactive regions. Next, atomic layer deposition of titanium dioxide produces an etch-resistant hard mask pattern on these regions. Reactive ion etching then transfers the mask pattern onto Si with pattern height of 17 nm, critical dimension of approximately 6 nm, and full-pitch down to 13 nm. The effects of linewidth, template atomic defect density, and line-edge roughness are examined in .

TSD: A GENERATIVE RESEARCH PLATFORM IN THE AGE OF THE PANDEMICS

Platform based IT ecosystems enable new ways of organizing the relation between consumers and pro- viders. This also applies to research platforms established to facilitate the relationship between individ- uals and organizations in producing knowledge across professional research work. This is especially important when researchers need to store, safeguard, and secure real-time harvested data during a pandemic. The platform literature has previously addressed consumer-oriented generativity and how the dynamic interaction between consumers and platform owners affords new business ideas. In re- search platforms, we propose, these mechanisms are different since the consumerization aspects are less prominent. To investigate this interest, we ask: How can we establish a generative platform for real-time research? We frame our study within the platform literature and the literature on generativity. Our empirical evi- dence is a research platform called TSD (Tjenester (services) for sensitive data), which became central to a corona study in Norway. We offer two contributions; first, we establish a generativity framework and applies this framework to explain how generativity in research platforms differ from consumer platforms. Then we analyze in-depth, generativity in research platforms. Second, we contribute by demonstrating how this generativity framework can explain the fast establishment of a real-time re- search study.
System-Forming Dominant of Professional Qualities Formation of a Teacher on the Basis of Contextual-Network Technology

Due to the rapid globalization of the modern educational space, pedagogical education in Russia characterized by the process of large-scale modernization, which has led to growing problem of educator training as a multicultural personality capable of network collaboration with educators of both domestic and foreign countries. Orientation on the educator training capable of expressing responsibility and self-independence in the decision making, creativity and initiative is becoming the primary trend in the State policy in the context of educational sphere, that is viewed as the factor of development not only of the personality of a student, but also of an educator. The goal of the paper is to argue a theoretical foundation of the professional qualities of an educator in the context of contextual-network technology, the basis of which are the ideas of contextual education, androgogy, ideas of network learning. These trends are more focused on the problems of the professional qualities formation of an educator in the context of a health-saving educational environment in which the personalities of education interact to obtain a holistic picture of the world. However, the practical experience of professional qualities formation showed insufficient development of this problem in accordance with the requirements of the FSES HE and the introduction of digital technologies in the learning process, which is confirmed by regulatory documents, in particular the Russian Government's Resolution on the Approval of the State Program of the Russian Federation "Education Development (from 26.2017 No.1642). "All abovementioned trends have updated the need to develop the problem of professional qualities formation of an educator. Research methods of research are: theoretical (analysis of philosophical, psychological and educational literature, theoretical modeling of structural and meaningful basis of the study process; empirical (questionnaire, business games, projects); diagnostic (analysis of activity products, summative phase, pedagogical experiment, methods of mathematical statistics).

Crowd Counting with Stacked Pooling for Boosting Scale Invariance

—In this work, we take insight into the crowd counting problem by exploring the phenomenon of cross-scale visual similarity caused by perspective distortions. It is a quite common phenomenon in crowd scenarios, suggesting the crowd counting model to enable a good performance of scale invariance. Existing deep crowd counting approaches mainly focus on the multi-scale techniques over convolutional layers to capture scale-adaptive features, resulting in high computing costs. In this paper, we propose simple but effective pooling variants, i.e., multi-kernel pooling and stacked pooling, to take place of the vanilla pooling layers in convolutional neural networks (CNNs) for boosting the scale invariance. Speciﬁcally, the multi-kernel pooling comprises of pooling kernels with multiple receptive ﬁelds to capture the responses at multi-scale local ranges. The stacked pooling is an equivalent form of multi-kernel pooling, while it reduces considerable computing cost. Our proposed pooling modules do not introduce extra parameters and can be easily implemented in practice. Empirical studies on two benchmark crowd counting datasets show that the proposed pooling modules beat the vanilla pooling layer in most experimental cases.
The Effect of Rapid Rotation & Stratification on Homogeneous Turbulent Shear Flows via Linear Kinematic Simulations

The evolution and statistics of developed turbulence quite often can dominate the resulting global system dynamics. This is especially the case for example in planetary boundary layers (atmospheric or oceanic) and astrophysical discs, where the structure of turbulence is influenced by the background shear, as well as system rotation and stable stratification. For example, the source and structure of turbulence in non-ionised Keplerian accretion discs (such as our very own nascent solar system) is still largely unknown [Johnson and Gammie, 2005], but is known to critically influence the protostellar accretion rate as well as the ability to seed planetesimal formation. It is thus desirable to understand more fully the exact turbulence suppression or enhancement mechanisms active in rotating and stratified homogeneous shear flows. To this end, the structure and short-time evolution of turbulence in a rotating, stratified, and shearing domain will be studied via Rapid Distortion Theory (RDT) [Batchelor and Proudman, 1954]. Even though turbulence is inherently nonlinear, the linearisation proposed by Batchelor can still give useful insight into the behaviour of turbulence unrelated to the cascade. Distinct from conventional linear stability analysis which considers the exponential growth of a single eigenmode, but whose end result is quite often turbulence, the objective of RDT is to capture the short-time evolution of this resulting turbulence. It thus effectively forms a link between linear stability analysis and the behaviour of developed turbulence. RDT may also be utilised to motivate construction of turbulence models; however, the scope of this paper will be restricted to the trends of either stabilisation or destabilisation of turbulent fluctuations. In particular, the evolution of turbulent fluctuations will be studied in a domain where the axis of rotation, shear, and stratification are aligned, as is often approximated in the atmospheric boundary layer. Deissler [1961] was the first to apply the ideas of RDT to study turbulence in plane shear flows. Similarly, Hanazaki and Hunt [2004] considered the effects of stable stratification on the spectrum of turbulence. Finally, Salhi and Cambon [2006] has explored particular analytic solutions to the RDT equations for the combined rotating, shearing, and stratified flows for the case with no streamwise fluctuations. Still much is yet unexplored for the evolution of 3D isotropic fluctuations in this situation where the axes of rotation and stratification are parallel. Nonetheless, many studies have used kinematic simulations (KS) of the RDT equations to evolve the case with these axes oriented perpendicular to each other (cf. Sagaut and Cambon [2008]), and so will be used as guidance.
