Supportive Therapy For Reducing Anxiety In Certified Nurse Students Who Are Confirmed Covid 19 Who Are Undergoing Home Quarantine

Covid 19 is a respiratory disease with a high transmission rate and can lead to death. The high number of cases day by day makes patients exposed to Covid-19, both those treated in hospitals and those who are home quarantine felt physical pain, also show somatic symptoms with high anxiety, so it can affect mental health. One of the efforts to overcome anxiety is with supportive therapy. The purpose of this study is to find out supportive therapy for reducing anxiety in certified nurse students who are confirmed Covid 19 who are undergoing home quarantine at the Muhammadiyah University of Gorontalo. This research is a quantitative research with pre-test and post-test designs without control group. The population in this study were certified nurse students who were confirmed Covid 19. The sampling technique used non-probability sampling with the quota sampling technique. The number of sample used was 18 people. Data analysis using paired t test. The results of the study after the intervention showed that there was no anxiety as much as 33.3% and mild anxiety 66.7%. The difference in the average level of anxiety before and after supportive therapy was obtained p value of 0.0001. To reduce the level of anxiety providing psychological support will increase calm. Supportive therapy is also needed to support recovery and prevent further worsening of confirmed Covid-19 patients.
Combining Wilkinson Microwave Anisotropy Probe and Sloan Digital Sky Survey Quasar Data on Reionization Constrains Cosmological Parameters and Star Formation Efficiency

We present constraints on cosmological and star formation parameters based on combining observations from the Wilkinson Microwave Anisotropy Probe (WMAP) and high-redshift quasars from the Sloan Digital Sky Survey (SDSS). We use a semianalytic model for reionization that takes into account a number of important physical processes both within collapsing halos (e.g., H2 cooling) and in the intergalactic medium (e.g., H2 cooling, Compton cooling, and photoionization heating). We find that the Gunn-Peterson absorption data provide tight constraints on the power spectrum at small scales in a manner analogous to that derived from the cluster mass function. Assuming that the efficiency of producing UV photons per baryon is constant, the constraint takes on the form σ8Ω ≈ 0.33 in a flat, Λ-dominated universe with h = 0.72, n = 0.99, and Ωbh2 = 0.024. However, the calculated optical depth to electron scattering of τes ~ 0.06 is well below the value found by WMAP of 0.17 ± (0.04 ~ 0.07). Since the WMAP constraints on τes are somewhat degenerate with the value of the spectral index n, we then permit the primordial spectral index n to float and consider the 1 σ WMAP-only determination of Ω0h2 = 0.14 ± 0.02 (implying Ω0 = 0.27 ± 0.04), while normalizing the power spectrum using WMAP. In addition, we allow the UV efficiency to be greater in the past. Combining the WMAP constraints with the quasar transmission data, our analysis then favors a model with τes = 0.11(Ω0/0.27)-1, n = 0.96(Ω0/0.27)-0.57, implying a WMAP normalization of σ8 = 0.83(Ω0/0.27)0.53 (all at 95% confidence) and an effective UV efficiency that was at least ~10 times greater at z ≫ 6. The implied UV efficiency is not unreasonable for stars, spanning the range from 10-5.5 to 10-4. These results indicate that the quasar and WMAP observations are consistent. If future observations confirm an optical depth to electron scattering τes ~ 0.1, then it would appear that no more "exotic" sources of UV photons, such as miniquasars or active galactic nuclei, are necessary. However, unless one considers more radical sources of UV photons or alternative forms for the power spectrum of density fluctuations, one cannot achieve a value of τes ≳ 0.17 without violating some combination of constraints from quasar transmission data from z = 4 to 6 and WMAP measurements at large scales.
Gas flow in near surface comet like porous structures: Application to 67P/Churyumov-Gerasimenko

We performed an investigation of a comet like porous surface to study how sub-surface sublimation with subsequent flow through the porous medium can lead to higher gas temperatures at the surface. A higher gas temperature of the emitted gas at the surface layer, compared to the sublimation temperature, will lead to higher gas speeds as the gas expands into the vacuum thus altering the flow properties on larger scales (kilometres away from the surface). Unlike previous models that have used modelled artificial structures, we used Earth rock samples with a porosity in the range 24–92% obtained from X-ray micro computed tomography (micro-CT) scans with resolution of some μm. Micro-CT scanning technology provides 3D images of the pore samples. The direct simulation Monte Carlo (DSMC) method for the rarefied gas dynamics is directly applied on the digital rock samples in an unstructured mesh to determine the gas densities, temperatures and speeds within the porous medium and a few centimetres above the surface. The thicknesses of the rock samples were comparable to the diurnal thermal skin depth (5 cm). H2O was assumed to be the outgassing species. We correlated the coma temperatures and other properties of the flow with the rock porosities. The results are discussed as an input to analysis of data from the Microwave Instrument on Rosetta Orbiter (MIRO) on the 67P/ChuryumovGerasimenko.
STEROL ISOLATION AND FULL CHARACTERISATION OF TWO GLUCOSIDES FROM TEUCRIUM BARBEYANUM ASCHERS

:-The genus Teucrium is used in folk medicine for a long time as hypoglycemic and hypolipidemic agents, and showed a wide spectrum of interesting biological activities. In this study, the aerial parts of Teucrium barbeyanum which collected from Ras El-Hilal, Libya were subject of extraction with different organic solvents, followed by extensive columns chromatography and crystallization using various solvent systems in order to isolate compounds. Dichloromethane extract afforded two sterol glucosides which successfully identified as sitosterol-3-O-β-D-glucoside and the rare compound, clerosterol-3-O-β-D-glucoside. The protons, carbons and OHgroups were fully assigned by means of spectroscopic techniques including NMR (1H, 13C, DEPT-135, 90 and Q, COSY, HSQC and HMBC) and IR, and Electron Impact Mass Spectrometry.
A systematic review of computer-mediated communications in Chinese as a foreign language from 2008 to 2022: Research contexts, theoretical foundations and methodology, affordances and limitations

The Covid-19 pandemic has demonstrated how ubiquitous and pervasive technology to support communication and collaboration has become in people’s lives. This article seeks to provide an overview of the use of computer-mediated communication (CMC) in learning Chinese as a foreign language (CFL). The authors systematically reviewed 68 empirical research articles and 3 review articles published between 2008 and 2022 (early April). This in-depth review aims to investigate: (1) the characteristics of CMC-facilitated CFL learning in the worldwide context;(2) common theoretical foundations and methodological approaches;(3) CFL learners’ linguistic and intercultural communicative competence development through CMC;(4) affordances and limitations of CMC in the field of CFL research. Findings from this review suggest that the majority of studies were in formal education contexts within Anglosphere countries. The most commonly acknowledged theoretical foundations in CFL were well aligned with the wider second language acquisition (SLA) domain. A mixed-methods approach was the predominant methodological approach undertaken in the selected papers, with a small number of experimental or quasi-experimental studies between 2008 and 2022. The analysis also identified a clear research gap in relation to young CFL learners in the literature. The predominance of studies at ab initio level would suggest that more research is needed on younger CFL learners and on intermediate and advanced CFL learners using CMC. Additionally, the synthesized affordances of applying CMC technologies in CFL practice from this review were: (1) active engagement;(2) authentic communication;(3) learner centeredness;and (4) opportunities for practice and discovery. By addressing technological and individual CMC implementation limitations in a CFL context, suggestions and recommendations about further research and teaching practice are highlighted in the conclusion section.

Deterministic and stochastic analysis of a prey-dependent predator–prey system

This paper reports on studies of the deterministic and stochastic behaviours of a predator–prey system with prey-dependent response function. The first part of the paper deals with the deterministic analysis of uniform boundedness, permanence, stability and bifurcation. In the second part the reproductive and mortality factors of the prey and predator species are perturbed by coloured noise to simulate a random environment. Using spectral density analysis it has been shown that this system exhibits large fluctuations for high amplitude random forces. When k, the carrying capacity of prey, tends to a particular value k*, this system exhibits abnormally large fluctuations with increasing time with a periodic background noise. A comparative study of the deterministic and stochastic criteria of stability is also established.
Radiative Properties of Carbonaceous Aerosols

Abstract The complex index of refraction for various carbonaceous materials is presented for wavelengths from 0. 3μ≲λ≲20μ. An ensemble of spherical carbon dust particles represented by two size distributions typical of urban aerosols is utilized in conjunction with Mic theory to determine the extinction coefficient, the albedo for single scattering, the asymmetry factor, 〈cosθ〉, the average phase function, and the polarization for wavelengths 0. 3μ≲λ≲15μ.
Hydrogen-mediated structural changes of amorphous and microcrystalline silicon

Amorphous $(a\ensuremath{-}\mathrm{S}\mathrm{i}:\mathrm{H})$ and microcrystalline silicon $(\ensuremath{\mu}c\ensuremath{-}\mathrm{S}\mathrm{i}:\mathrm{H})$ samples were exposed to a hydrogen plasma in a clean electron-cyclotron-resonance system. We present unequivocal experimental evidence for hydrogen-induced crystallization of $a\ensuremath{-}\mathrm{S}\mathrm{i}:\mathrm{H}. $ A 60-min post-hydrogenation at 325 \ifmmode^\circ\else\textdegree\fi{}C resulted in an increase of the crystalline fraction by 10--15 %. Similar H plasma treatments performed on $\ensuremath{\mu}c\ensuremath{-}\mathrm{S}\mathrm{i}:\mathrm{H}$ caused a decrease of the crystalline fraction ${X}_{C}$ by up to 20%. The lack of an amorphous phase in posthydrogenated c-Si shows that the presence of grain boundaries is required to observe hydrogen-induced conversion of crystalline to amorphous silicon. We propose that the driving force for the decrease of ${X}_{C}$ is the minimization of the lattice-strain energy.
The lattice of completely regular semigroup varieties

Abstract A completely regular semigroup is a semigroup which is a union of groups. The class CR of completely regular semigroups forms a variety. On the lattice L (CR) of completely regular semigroup varieties we define two closure operations which induce complete congruences. The consideration of a third complete congruence on L (CR) yields a subdirect decomposition of L (CR). Using these results we show that L (CR) is arguesian. This confirms the (tacit) conjecture that L (CR) is modular.
Inference of Dynamic Generalized Linear Models: On‐Line Computation and Appraisal

The purpose of this paper is to provide a critical discussion on real‐time estimation of dynamic generalized linear models. We describe and contrast three estimation schemes, the first of which is based on conjugate analysis and linear Bayes methods, the second based on posterior mode estimation, and the third based on sequential Monte Carlo sampling methods, also known as particle filters. For the first scheme, we give a summary of inference components, such as prior/posterior and forecast densities, for the most common response distributions. Considering data of arrivals of tourists in Cyprus, we illustrate the Poisson model, providing a comparative analysis of the above three schemes.
Aerodynamic Characterization of Linear Aerospike Nozzles in Off-Design Flight Conditions

Spike surface flowfields and base wake behaviors of clustered linear aerospike nozzles under the presence of external flow were characterized using surface pressure measurements, flow visualizations using the background-oriented schlieren method, and theoretical modeling. The test model consisted of three clustered cell nozzle modules or a nonclustered two-dimensional nozzle with an exit Mach number of 3.5, followed by a straight section and a contoured spike. The model was exposed to an external flow of Mach 2.0 to simulate off-design transonic flight conditions. The measured surface pressure distributions indicated that the entire flowfield on the spike surface became more two-dimensional under the presence of external flow. Periodic compressions and expansions of the cell nozzle jet were eliminated, but the pressure continued to increase downstream. The results of the flow visualizations found that this was mainly governed by the external flow that controls the jet expansion by forming a slip surface.
Morphology and ultrastructure-related local mechanical properties of PC-12 cells studied by integrating atomic force microscopy and immunofluorescence imaging

A cost-effective method that integrates high-resolution morphology using an atomic force microscope and immunofluorescence imaging for measuring the local mechanical properties of a cell was developed. By considering the normal indentation conditions and the distribution of the underlying cytoskeleton, a criterion for selecting indentation sites was proposed. PC-12 cells cultivated under normal and high D-glucose medium are employed to demonstrate the applicability of the proposed method. The apparent Young's modulus for each indentation site was estimated by fitting the data with a pyramidal punch contact mechanics model. The results showed that the cell bodies cultivated in the high D-glucose medium were higher but their growth cones were shorter than those cultivated in a normal medium. The Young's moduli of the growth cones were positively correlated with the density of the actin filament in the cytoskeleton. The Young's moduli at the growth cone and the nucleus region of cells cultivated in the high D-glucose medium were higher and lower, respectively, than those of the control group. The results demonstrated the integrated method could correlate local mechanical properties and distribution of actin filament of the growth cone of PC-12 cell.
On Raghunathan’s measure conjecture

This paper represents the last in our three-part series on Raghunathan's measure conjecture (see [R1], [R2] for Parts I and II). More specifically, let G be a real Lie group (all groups in this paper are assumed to be second countable) with the Lie algebra (, r a discrete subgroup of G and ir: G-> r \ G the projection lwg) = rg. The group G acts by right translations on r \ G, x ->x g, x E r \ G, g E G. Let gt be a Borel probability measure on r \ G. Define
Real-time PCR has advantages over culture-based methods in identifying major airway bacterial pathogens in chronic obstructive pulmonary disease: Results from three clinical studies in Europe and North America

Introduction We compared the performance of real-time PCR with culture-based methods for identifying bacteria in sputum samples from patients with chronic obstructive pulmonary disease (COPD) in three studies. Methods This was an exploratory analysis of sputum samples collected during an observational study of 127 patients (AERIS; NCT01360398), phase 2 study of 145 patients (NTHI-004; NCT02075541), and phase 2b study of 606 patients (NTHI-MCAT-002; NCT03281876). Bacteria were identified by culture-based microbiological methods in local laboratories using fresh samples or by real-time PCR in a central laboratory using frozen samples. Haemophilus influenzae positivity with culture was differentiated from H. haemolyticus positivity by microarray analysis or PCR. The feasibility of bacterial detection by culture-based methods on previously frozen samples was also examined in the NTHI-004 study. Results Bacterial detection results from both culture-based and PCR assays were available from 2,293 samples from AERIS, 974 from the NTHI-004 study, and 1736 from the NTHI-MCAT-002 study. Quantitative real-time PCR (qPCR) showed higher positivity rates than culture for H. influenzae (percentages for each study: 43.4% versus 26.2%, 47.1% versus 23.6%, 32.7% versus 10.4%) and Moraxella catarrhalis (12.9% versus 6.3%, 19.0% versus 6.0%, 15.5% versus 4.1%). In the NTHI-004 and NTHI-MCAT-002 studies, positivity rates were higher with qPCR for Streptococcus pneumoniae (15.6% versus 6.1%, 15.5% versus 3.8%); in AERIS, a lower rate with qPCR than with culture (11.0% versus 17.4%) was explained by misidentification of S. pseudopneumoniae/mitis isolates via conventional microbiological methods. Concordance analysis showed lowest overall agreement for H. influenzae (82.0%, 75.6%, 77.6%), due mainly to culture-negative/qPCR-positive samples, indicating lower sensitivity of the culture-based methods. The lowest positive agreement (culture-positive/qPCR-positive samples) was observed for S. pneumoniae (35.1%, 71.2%, 71.2%). Bacterial load values for each species showed a proportion of culture-negative samples with a load detected by qPCR; for some samples, the loads were in line with those observed in culture-positive samples. In the NTHI-004 study, of fresh samples that tested culture-positive, less than 50% remained culture-positive when tested from freeze/thawed samples. In the NTHI-004 study, of fresh samples that tested culture-positive, less than 50% remained culture-positive when tested from freeze/thawed samples. Discussion Real-time PCR on frozen sputum samples has enhanced sensitivity and specificity over culture-based methods, supporting its use for the identification of common respiratory bacterial species in patients with COPD.

The LHC main dipoles and quadrupoles toward series production

The Large Hadron Collider (LHC) is under construction at CERN. Most of its 27 km underground tunnel will be filled with superconducting magnets, mainly 15 m long dipoles and 3.3 m long quadrupoles. In total 1248 dipole and 400 quadrupole magnets will be built (including spares), all wound with copper stabilized NbTi Rutherford cables and designed to operate in superfluid helium at 1.9 K. The dipoles operative field is 8.3 T, the system being designed for possible operation up to 9 T (ultimate field). The pre-series dipole production has started in 2000 in three companies while the series dipole construction will start at the beginning of 2003. As far as quadrupoles are concerned, the prototypal phase (carried out at CEA-Saclay, F) is followed directly by the series construction, started in March 2002. In the paper the magnet main characteristics are reviewed and the special tooling, put in place to fulfill the mass production with suitable accuracy and safety margin, is described. The results obtained on the first fifteen pre-series magnets as well as the effect of the corrective actions taken to meet the necessary field quality are discussed. Finally a realistic plan of the project, foreseeing that last dipoles are delivered in summer 2006, is presented.
Hysteresis in Adiabatic Dynamical Systems: an Introduction

We give a nontechnical description of the behaviour of dynamical systems governed by two distinct time scales. We discuss in particular memory effects, such as bifurcation delay and hysteresis, and comment the scaling behaviour of hysteresis cycles. These properties are illustrated on a few simple examples.
Modelling of the structure-property relationships in the α-quartz structures

The molecular mechanism has been employed to model the structure-property relationships of auxetic material with tetrahedral framework at the atomistic level. The germania α–quartz subject uniaxial stress loading in z direction will be investigated. The strain-dependent structure and mechanical properties will be predicted from the force field based simulations, including the transformation from positive-to-negative Poisson’s ratio behaviour and vice versa.
A systematic review of UTAUT2 constructs’ analysis among MSMEs in non-OECD countries

Purpose This paper aims to analyse the unified theory of acceptance and use of technology (UTAUT) and UTAUT2 constructs used in research on information and communication technology (ICT) adoption and use among micro, small and medium enterprises (MSMEs) in non-organisation for economic co-operation and development (OECD) countries. It also investigates the areas of ICT adoption along the value chain in studies using these constructs. Design/methodology/approach Systematic literature review (SLR) was conducted, where 910 studies were retrieved manually in five academic databases. Forty-eight studies were finalised after four filtration levels. Findings Majority of the studies were published within the past six years, and 85.42% were studies in the form of journal papers. UTAUT constructs more researched compared to UTAUT2 constructs. More than half of the studies investigated ICT application in value chain boundaries, while 16 studies were organisation-wide studies. Research limitations/implications With developments in MSMEs’ technology, the UTAUT2 model must be expanded to internal company operations including finance and infrastructure maintenance. To boost competitiveness and productivity, non-OECD authorities should focus on the cost and user-centric characteristics of MSMEs’ technology adoption. Originality/value Although SLRs on UTAUT and UTAUT2 constructs have been attempted previously, this study contributes to the body of knowledge by focusing analysis on the application of those constructs on MSMEs in non-OECD countries and also by situating ICT adoption along the value chain of enterprises.
