Investigation of tokamak turbulent avalanches using wave-kinetic formulation in toroidal geometry

The interplay between toroidal drift-wave turbulence and tokamak profiles is investigated using a wave-kinetic description. The coupled system is used to investigate the interplay between marginally stable toroidal drift-wave turbulence and geodesic acoustic modes (GAMs). The coupled system is found to be unstable. Notably, the most unstable mode corresponds to the resonance between the turbulent wave radial group velocity and the GAM phase velocity. For a low-field-side ballooned drift-wave growth, a background flow shear breaks the symmetry between inwards- and outwards-travelling instabilities. Although this turbulence–GAM coupling may not be the primary driver for avalanches in standard core ion temperature gradient simulations, this mechanism is generic and displays many of the expected features, and should be of interest in several other regimes, which include towards the edge or in the presence of energetic particles.
Density diagnostics of photoionized outflows in active galactic nuclei

Abstract Photoionized outflows in active galactic nuclei (AGNs) are thought to influence their circumnuclear and host galactic environment. However, the distance of the outflow with respect to the black hole is poorly constrained, which limits our understanding of the kinetic power by the outflow. Therefore, the impact of AGN outflows on their host galaxies is uncertain. If the density of the outflow is known, its distance can be derived. Density measurement via variability studies and density sensitive lines have been used, albeit not very effective in the X-ray band. Good measurements are rather demanding or challenging for the current generation of (grating) spectrometers. The next generation of spectrometers will certainly provide data with better quality and large quantity, leading to tight constraints on the location and the kinetic power of AGN outflows. This contribution summarizes the state-of-the-art in this field.
Carbonaceous chondrite meteorites as a record of protoplanetary disk conditions

Abstract Chondritic meteorites, and especially the most volatile-rich chondrites, the carbonaceous chondrites, preserve a record of the solar protoplanetary disk dust component and how it has been changed both in the disk environment itself and in its asteroidal parent body. Here we review some of the key features of carbonaceous chondrites and report some new data on their organics component. These show that the nebula reached temperature of >10000C, but only very locally, to produce chondrules. Most meteoritic material underwent thermal and/or aqueous processing, but some retain delicate nebular components such as complex organic molecules and amorphous silicates.
The Association between Psychological Capital and Burnout: The Moderating Effect of Job Fulfilment

The study aims to focus on determining the association among the psychological capital and employee burnout along with the moderating effect of job fulfilment. This study is quantitative in nature in which the data has been gathered from the primary sources of information. The researcher instrument used in the study is survey questionnaire. The researcher has adopted the convenience sampling in order to gather the data. The data in this study is analysed with the help of SEM technique in which CFA and path analysis were considered using SmartPLS. The analysis carried out in this study has determined that there is a significant effect of psychological capital over the employee burnout which is also positive. On the other hand, with respect to the moderating effect job fulfilment, it has been determined that there is insignificant moderating effect of job fulfilment over the relationship of psychological capital and employee burnout. However, the direct effect of job fulfilment was determined over the employee burnout. This study has focused on determining the association of psychological capital over the employee burnout in the moderation of job fulfilment. This study is restricted to psychological capital as the factor which influence the employee burnout. However, there are other factors which must be considered while determining the causes of employee burnout.
Production rates and metabolism of short-chain fatty acids in the colon and whole body using stable isotopes

Short-chain fatty acids (SCFA; mainly acetate, propionate and butyrate) are largely produced in non-ruminants during the colonic bacterial fermentation of non-digestible carbohydrates. These intestinal exogenous SCFA pass in part through the splanchnic bed and reach the peripheral bloodstream, mixing with the endogenous circulating SCFA. The whole-body turnover of SCFA is thus composed of an endogenous peripheral turnover and an exogenous production that depends on dietary intake of non-digestible carbohydrates. In the present work methods were developed for determining the SCFA turnover in animals and in human subjects using stable isotopes. The original studies performed to determine endogenous and exogenous metabolism of SCFA in animals and in human subjects are summarised. Using intravenous infusion of 13C-labelled SCFA the whole-body turnover of acetate, propionate and butyrate was assessed in rats in a fasted state. The endogenous turnover of acetate and its oxidation were determined in healthy human subjects in the post-absorptive state, using intravenous infusion of[l-13C]acetate. Intragastric tracer infusions were performed to evaluate the splanchnic first-pass retention of acetate in adults. Finally, an original model was developed in healthy human subjects using intravenous infusion of[l-13C]acetate to determine in vivo the true colonic acetate production after ingestion of a non-digestible disaccharide. These present studies using stable isotopes provide the basis for a novel strategy to evaluate in vivo, in human subjects, the production of SCFA in the large intestine.
Solar oscillations

Abstract Study of solar oscillations has provided us detailed information about solar structure and dynamics. These in turn provide a test of theories of stellar structure and evolution as well as theories of angular momentum transfer and dynamo. Some of these results about the solar structure and its implication on the recent revision of heavy element abundances are described. Apart from these the solar cycle variations in the rotation rate and its gradients are also discussed.
IMPACT OF PSYCHOSOCIAL INTERVENTION ON THE QUALITY OF LIFE FOR THE PATIENTS WITH HEPATITIS C RECEIVING INTERFERON AND RIBAVIRIN THERAPY

Background: Hepatitis C virus is a chronic medical condition that has broad implications for a person’s physical and mental wellbeing. In order for people with hepatitis C virus (HCV) infection to effectively deal with this condition, it is vital that they get great therapeutic care and support from many different sources as possible medical professionals, family and friends, and others living with hepatitis C. The purpose of this study was to evaluate the impact of psychosocial intervention on the quality of life in patients with chronic hepatitis C virus infection. Methods: A quasi-experimental study was conducted in this study. Results: The experimental and control groups were the same concerning the effective factors on the quality of life, such as age, sex, etc (P > 0.05). There was no significant difference between QOL mean score of both groups before the intervention, however the QoL significantly improved in the experimental group after the intervention (P= 0.001), while the QoL decreased in control group. Conclusion: The results of this study confirmed the beneficial effects of psychosocial intervention on the health related quality of life. Therefore, all hepatitis C patients should be counseled and encouraged to participate in educational programs at the time of diagnosis to reduce unnecessary behavioral changes and stigmatization perceptions to improve quality of life.
Dual Role of Hydrogen in Low Temperature Plasma Enhanced Carbon Nanotube Growth

The gas composition during carbon nanotube (CNT) growth has received much attention because it largely determines the properties of the nanotubes and the yield of the growth. Here, we investigated the influence of hydrogen to hydrocarbon ratio on the CNT growth at low temperatures (<500 °C) using plasma-enhanced chemical vapor deposition (PECVD). Hydrogen was found to have a dual role during the growth process on TiN using catalytic nickel or cobalt nanoparticles. On the one hand, when the ratio of hydrogen to hydrocarbon partial pressure was low, CNT growth terminated well before the total process duration. As a result, no CNT growth was observed without hydrogen added to the gas mixture. The growth process could not be prolonged or reactivated upon performing in situ reducing or oxidizing cycles. On the other hand, when [H2]/[C2Hx] was high, catalyst dependent etching of the CNT forest occurred. For nickel catalyzed CNT growth, the high relative hydrogen content resulted in etching of the CNT forest, wh.
Discovery of new changing look in NGC 1566

Abstract We present continuation of the multi-wavelength (from X-ray to optical) monitoring of the nearby changing look (CL) active galactic nucleus in the galaxy NGC 1566 performed with the Neil Gehrels Swift Observatory,the MASTER Global Robotic Network over the period 2007–2019. We also present continuation of optical spectroscopy using the South African Astronomical Observatory 1.9-m telescope between Aug. 2018 and Mar. 2019. We investigate remarkable re-brightenings in of the light curve following the decline from the bright phase observed at Dec. 2018 and at the end of May 2019. For the last optical spectra (31 Nov. 2018–28 Mar. 2019) we see dramatic changes compared to 2 Aug. 2018, accompanied by the fading of broad emission lines and high-ionization [FeX]6374Å line. Effectively, one more CL was observed for this object: changing from Sy1.2 to the low state as Sy 1.8–Sy1.9 type. Some possible explanations of the observed CL are discussed.
CLINICAL EFFICACY OF GIOMER VERSUS SODIUM FLUORIDE VARNISH FOR MANAGEMENT OF HYPERSENSITIVITY: RANDOMIZED CONTROL TRAIL

Aim: to assess the clinical effectiveness of Giomer varnish in comparison to sodium fluoride in reducing hypersensitivity. Methodology: Using a Split mouth design, 66 participants were enrolled. Each participant should have at least two sensitive teeth in different sides of the same jaw, with a visual analogue scale score two or more. Teeth were examined by using different stimuli: Evaporative, thermal and tactile stimuli. Sides were categorized randomly into two groups according to the desensitizing agents used either sodium fluoride or Giomer. Degree of Hypersensitivity was assessed by visual analogue scale (VAS) before the application of the agents , immediately after , 1 week and one month later . Data were analyzed using Two way ANOVA, partial eta-squared, Kruskal-Wallis, Bonferroni-corrected Wilcoxon, Mann-Whitney test and Chi-square tests. Absolute risk, relative risk, relative risk reduction with 95% confidence interval. Results: Sodium fluoride exhibited high VAS scale at T1 3.39(1.11), T2 3.21(0.99) and T4 3.13(1.01) with a non-statistical difference between them. While at T3 statistically lower VAS scale 1.30 (0.9) was shown in this group. Giomer exhibited high VAS scale at T1 3.79(1.5) followed by T2 2.17(0.57) and T4 2.56(1.87) with a non-statistical difference between them. While at T3 lower VAS scale 0.17(0.57) was shown in this group. At T2 and T3, Giomer revealed statistically lower VAS scale and it exhibited a relative risk reduction by 83% at T3 and 24% at T4. Conclusion: Giomer varnish is a promising desensitizing agent, which can replace sodium fluoride varnish in management of hypersensitivity.
Effect of Propolis as a Feed Additive on Nutritional and Productive Performance of Pregnant Ewes and their Lambs under Halaib-Shalateen Pastures Condition

Thirty, 3-4 year of age, female Abu-duleik sheep, local breed, in late pregnancy period were chosen to study the effect of feeding two levels from propolis(P)during late pregnancy and postpartum period on nutritional and productive performance. Animals were divided into three equal groups(10 ewes in each). The first group was fed on concentrate feed mixture(CFM)without propolis (P0) as a control ration, while, the second(P1)and third(P2)groups received the control ration supplemented with propolis at the levels of 100 and 200 mg /kg DM, respectively.All animals were fed CFM at 2.5% of live body weight(LBW)and allowed to graze on Panicum turgidum as a basal range plant for 8 hours daily. The results could be summarized as follows:Propolis treatments led to significant increases in all nutrients digestibility.Propolis improved ruminal condition represented by a decrease(P<0.05)in pH, ammonia-N and volatile fatty acids concentrations. Propolis treatments showed lower(P<0.05)total bacteria count(X 1010/ml),especially ruminal gram positive bacteria, compared with control treatment.Also, 4% fat correct milk yield and percentage of constituents (fat, protein and total solid) increase(P<0.05)with increasing the level of propolis. Lambs belonging to the P1 and P2 groups recorded a significant increase in the average daily gain, total gain and weaning weight compared to lambs belonging to the control group. Propolis treatments improved ewe's production index represented by weaning weight index percentage at a rate of22.60 and 33.53%for P1 and P2 ewes compared with control ewes. Generally,propolis additive under arid-area rangelands condition improved nutritional and productive performance of pregnant ewes and their lambs beside improved economic efficiency
The spectral evolution of cool white dwarfs

Abstract Empirically characterizing the spectral evolution of cool white dwarfs is a prerequisite to understanding the physical processes that shape the evolution of these old objects. However, the high photospheric densities of cool helium-rich atmospheres seriously complicate the study of those stars. We have recently developed an updated atmosphere code that is appropriate for high densities and that can model any cool white dwarf (including DZs and DQpecs). Here, we present recent advances in our understanding of the spectral evolution of cool white dwarfs that were made possible thanks to these improved models. We discuss in particular the evolution of the hydrogen-rich to helium-rich ratio at low effective temperatures as well as the DQ→ DQpec transition.
Interaction of transferrin with cefuroxime sodium

ABSTRACT The interaction between cefuroxime sodium and transferrin in physiological buffer (pH 7.4) was investigated by spectroscopy at 298, 310, and 318 K. The analysis of data indicated that quenching mechanism of the transferrin–cefuroxime sodium system was probably static. The electrostatic force played an important role in the conjugation reaction between transferrin and cefuroxime sodium. The order of magnitude of binding constants (Ka) was 104, and the number of binding site (n) in the binary system was approximately equal to 1. Besides, the values of Hill’s coefficients were lager than 1, which indicated very weakly positive cooperativity in the transferrin–cefuroxime sodium system. The synchronous fluorescence spectra and circular dichroism spectra revealed that the microenvironment and the conformation of transferrin were changed during the binding reaction.
DOES SWITCHING BARRIERS MEDIATE THE INFLUENCE OF CUSTOMER TRUST TO CUSTOMER LOYALTY?

To be loyal to one of cellular operator brand was difficult. It happened because customer had lack of communication technology knowledge while their necessity of it was high. Customer trust had important role to influence customer loyalty. They could be loyal to one of cellular operator brand because they could not change it or even, they did not want it. This condition was called switching barriers. The aim of this research was to determine the relationship between switching barrier, customer trust and customer loyalty in cellular operator brands. The respondents of this study were students from several different university in East Java, Indonesia. 284 questionnaires collected and analyzed used SmartPLS 3.0. The result showed that switching barriers were able to mediated the influence of customer trust to customer loyalty.
Under Darwin's Cosh? Neo-Aristotelian Thinking in Environmental Ethics

As a first shot, one might say that environmental ethics is concerned distinctively with the moral relations that exist between, on the one hand, human beings and, on the other, the non-human natural environment. But this really is only a first shot. For example, one might be inclined to think that at least some components of the non-human natural environment (non-human animals, plants, species, forests, rivers, ecosystems, or whatever) have independent moral status, that is, are morally considerable in their own right, rather than being of moral interest only to the extent that they contribute to human well-being. If so, then one might be moved to claim that ethical matters involving the environment are best cashed out in terms of the dutes and responsibilities that human beings have to such components. If, however, one is inclined to deny independent moral status to the non-human natural environment or to any of its components, then one might be moved to claim that the ethical matters in question are exhaustively delineated by those moral relations existing between individual human beings, or between groups of human beings, in which the non-human natural environment figures. One key task for the environmental ethicist is to sort out which, if either, of these perspectives is the right one to adopt—as a general position or within particular contexts. I guess I don't need to tell you that things get pretty complicated pretty quickly.
Effect of PTMGDA-PEGMA dopant on PVDF ultrafiltration membrane

As a novel hydrophobic monomer, polytetrahydrofuran diacrylate (PTMGDA) was synthesized by the esterification reaction between polyethylene tetrahydrofuran (PTMG) and acryloyl chloride (AC). In situ free radical polymerization reaction method was utilized to fabricate poly (vinylidene fluoride) (PVDF)-PTMGDA-poly(ethylene oxide) dimethacrylate (PEGMA) ulrafiltration (UF) membranes. The performances of PVDF-PTMGDA-PEGMA UF membranes in terms of morphologies, mechanical properties, separation properties and hydrophilicities were investigated. The introduction of the PTMGDA-PEGMA dopants not only increased the membranes’ pure water flux, but also improved their mechanical properties and the dynamic contact angles. The addition of the PTMGDA/PEGMA dopants led to the formation of the finger-like structure in the membrane bulk. With the increase concentration of PTMGDA/PEGMA dopants, the porosity and the mean effective pore size increased. Those performances were coincide with the physicochemical properties of the casting solutions.
INTRODUCTION

This fourth volume of the editorial series British Envoys to Germany comprises the last sixteen years of the German Confederation, between the Dresden Conferences of 1851 and the war between Prussia and the majority of the other member states in 1866. Many historical accounts of German politics of the years 1851 to 1866 are influenced on the one hand by the legacy of the revolutionary events of 1848–1849 and on the other hand by the dissolution of the Confederation and Bismarck's unification of a German nation-state dominated by Prussian policies and politics. While the early 1850s can be seen as a period of ‘reaction’ and a negative response to popular social and political demands, the remainder of the period is generally discussed in terms of the struggle for mastery in Germany, particularly the political and ultimately military conflict between Prussia and the Austrian Empire. However, the envoys’ correspondence questions teleological accounts of the time between Dresden and Königgrätz. Throughout the 1850s and 1860s, British diplomatic representatives reported on all matters regarding the German states and the German Confederation. In addition to international affairs and bilateral relations, the dispatches also cover German politics, its federal dimensions, and the policies and societies of the federal states. Like other contemporary sources, the envoys’ reports provide strong evidence that the period 1851–1866 should be seen as more than just a time of transition between revolution and unification. In fact, the multifaceted views of British diplomatic representatives to Germany provide a much broader picture and substantiate the demand for understanding the time between 1851 and 1866 in its own right.
Effect of endurance training on body composition blood glucose and insulin among college boys

Identifying potential risk factors associated with the development of hypo kinetic diseases among teen age population and finding out preventive strategies is vital in today scenario as early intervention can prevent the onset of such diseases including coronary heart disease and Diabetes mellitus. The effects of an endurance training program on body composition fasting blood sugar and insulin was examined among forty male under graduate students (Age: 19.63 ± 1.27; Height: 1.70±0.06, Weight: 66.20± 13.35, BMI: 22.99 ± 4.38) who were randomly assigned either to an experimental group (N =20) or a Control Group (N = 20). The experimental group underwent an endurance training program for tewelve weeks while the control group maintained their regular routine. The experimental group trained three to five sessions in a week and 25 to 50 min per session with a gradual increase in the number of sessions and duration as the program progresses. Height, Weight, and BMI were measured before (Pre) and after (Post) the training program. Fasting blood samples were collected 24 hours before, and 48 hours after the training period and analyzed for blood glucose and insulin levels. The obtained data were statistically analyzed using ANACOVA to find out significant difference if any. The result shows a significant reduction in Body Weight, BMI, Fasting blood sugar and Insulin in the experimental group when compared with the control group.
Developing of the calixarene based diamide chemical sensor chip for detection of aromatic hydrocarbons’ vapors

In the present work, a new macrocycle materials (SB77) was selected and LangmuirBlodgett thin films of this macrocycle compounds were examined for its vapor sensing capabilities against vapor of aromatic BTX hydrocarbons (benzene, toluene, xylene) through Quartz Crystal Microbalance (QCM) technique. In accordance with this aim, the calix[4]arene LB thin films were prepared onto quartz crystal substrates. The characterization of SB77 LB thin film was performed for nine LB layers fabricated onto the quartz crystal. The frequency shifts and the mass changes for monolayer of these LB thin films were obtained as 32.35 Hz / per layer and 2206.65 ng (8.32 ng mm), respectively. All QCM results indicated that SB77 LB thin film chemical sensors exhibits high response, a good sensitivity and selectivity for benzene vapor at saturated or different concentrations than other aromatic hydrocarbon vapors. These LB thin film sensors with SB77 calix [4]arene macrocycle materials have been potential candidates for organic vapor sensing applications with simple and low cost preparation at room temperature.
