Evaluation of antimicrobial activity of Primula denticulata.

The aim of the present study was to evaluate the antibacterial and antifungal activities of Primula denticulata commonly called as “Primrose”. Different solvents viz. ethyl acetate, chloroform, butanol, ethanol, methanol were used for the preparation of the extracts. Antibacterial and antifungal studies were carried out using agar disc diffusion and broth dilution methods. During the study it was found that the ethyl acetate extract of P. denticulata exhibited potent growth inhibitory effect against three bacterial strains including Shigella flexneri, Pseudomonas aeruginosa and Escherichia coli. The ethyl acetate extract exhibited no significant activity against Salmonella typhimurium and Staphylococcus aureus at 500 g/ml and 750 g/ml concentrations. 250 g/ml and 500 g/ml concentrations of the ethyl acetate extract exhibited potent inhibition of three fungal strains including Aspergillus versicolor, Aspergillus Flavus and Candida albicans. The choloroform extract of P. denticulata was found to be effective against Shigella flexneri, Escherichia coli and Salmonella typhimurium strains. However, the extract showed no growth inhibitory effects against Pseudomonas aeruginosa and Salmonella typhimurium. The methanol extract of P. denticulata exhibited highest growth inhibition against Pseudomonas aeruginosa. We therefore propose that the plant may prove as an important source of antimicrobial molecules.
Messaging Media Perceptions and Preferences: An Exploratory Study

Although a significant amount of research has focused on traditional media choice and use and even on some of the “new” media, these studies have neglected Instant Messaging (IM) and Short Messaging Service (SMS). This study offers a novel exploration of students’ perceptions of and preferences for two new messaging media (IM and SMS) in the context of the use of other traditional and new communication media (face-to-face, telephone, and email) in their university learning activities. The findings reveal media richness is rated in decreasing order of face-to-face, telephone, IM, email and SMS. Face-to-face is the most preferred medium in most communication activities. Students preferred email in a manner similar to the telephone. This study has identified the importance of media experience, familiarity and frequency of use, when selecting media. The overall findings of this study support media richness theory.
Ecological significance indicators for an estimation of DNA quantity and purity by the use of RAPD technique for fish (S. aurita) at Libyan coastal areas

The paper presents findings of a study conducted in the western part of the coast in the Libyan cities of Tripoli (polluted with organic pollutants) and Sabratha. It deals with the molecular markers that require the extraction of genus and the genetic DNA extraction of genetic DNA in pure and sufficient concentration, compared with free genetic, i.e. free of contaminants, especially sugars Polysaccharides and phenolic compounds Polyphenols and proteins, which keep these molecules inherent to DNA during the process of extraction deposited with DNA. 24 samples of fish (S. aurita), 6 samples per month with 6 samples of muscle tissue of sardine’s fish as reference are collected. The random amplification multiple image RAPDs technique of DNA is used, to identify The effect of pollutants on sardine’s fish exposed to pollutants. Ecological Significance Indicators results are compared to the one obtained from reference samples, using polymerase chain reaction enzyme (PCR). The results show that there is a clear difference in the group. In addition, according to the molecular weight, there is disappearance of three of the packages respectively pack 2 (1000bp) & Pack 4 (300bp) & pack 5 (100bp). Finally, the paper shows that how the RAPD technique can easily assessed the estimation of DNA quantity and purity.
Measurements Admissions by condition and deciles of Index of Multiple Deprivation (IMD). Socioeconomic gradient measured as the relative index of inequality (RII, the slope of a linear regression of IMD on admissions adjusted for overall admission

Background and Aims In many countries conflicting gradients in alcohol consumption and alcohol-associated mortality have been observed. To understand this ‘alcohol harm paradox’ we analysed the socioeconomic gradient in alcohol-associated hospital admissions to test whether it was greater in conditions which were : (1) chronic (associated with longterm drinking) and partially alcohol-attributable, (2) chronic and wholly alcohol-attributable, (3) acute (associated with intoxication) and partially alcohol-attributable, (4) acute and wholly-alcohol attributable. Our aim was to clarify how (1) drinking patterns (e.g. intoxication linked to acute admissions or dependence linked to chronic conditions) and (2) non-alcohol causes (e.g. smoking and poor diet which are risks for partially alcoholattributable conditions) contribute to the paradox. Design Regression analysis testing the modifying effects of condition-group (1-4 above) and sex on the relationship between areas-based deprivation and admissions. Setting England, April 2010–March 2013 Participants 9.2 million English hospital admissions where a primary or secondary cause was one of 36 alcohol-associated conditions
Probiotic Potential of Five Lactobacillus Strains Isolated from Traditional Persian Yoghurt in Fars province , Iran : Viewing Through the Window of Phylogenetics

Probiotics are dietary supplements of live microorganisms which presence of them in gastrointestinal tract in sufficient quantities can be beneficial to host health. Amongst various bacterial strains, lactic acid bacteria (LAB) are the most common probiotic bacteria. The aims of this study were to isolate and identify potentially LAB probiotics from the fermented yoghurt products of townships and villages in Fars province, Iran. Thirty samples of traditional dairy products were collected from different regions of Fars province. Laboratory methods such as gram-staining, motility; and biochemical approaches including carbohydrate utilization and catalase activity were employed to isolate LAB and assess their relevant properties. In five final isolates, 16S rDNA genes were extracted, amplified through PCR and electrophoresed. These genes were then sequenced and compared with the library of the sequences of the NCBI databases. Five different isolates of Lactobacillus were identified and reported as the normal flora in traditional dairy products. These included L. acidophilus, L. delbrueckii subsp. bulgaricus, L. jensseni, L. cripatus and L. gasseri. Phylogenetic analysis revealed a genetic relationship between the five studied strains together and with some previously reported probiotic strains. The obtained strains are potentially probiotics and these isolates can be used in dairy product industries to achieve beneficial effects of probiotics.
Motivations for the Career Choice of Preservice Teachers in New South Wales, Australia and Ontario, Canada.

This study investigated and compared the reasons given by 40 preservice teachers in New South Wales (NSW), Australia, and Ontario, Canada, for their career choice, focusing on whether their motivations reflected the marked difference in the status and remuneration of teachers in NSW and Ontario. Preservice teachers participated in in-depth, focused, individual interviews in which they were asked to tell a little about themselves and why they decided to become teachers. The NSW students completed interviews during their first year of enrollment, and the Ontario students completed interviews at the beginning of their second year. Data analysis highlighted four categories of reasons: (1) little sense of personal agency (e.g., teaching by default or chance); (2) teaching as a means of gaining personal agency; (3) teaching as a means of assisting others to gain agency; and (4) self as a reform agent. The NSW student teachers had more diverse motivations than did their counterparts in Ontario, who mostly cited a vocation for teaching. In general, the responses of the Ontario preservice teachers indicated higher perceptions of personal agency than did those of the NSW preservice teachers, possibly a reflection of the higher professional status and salaries accorded teachers in Ontario.

The relationship between type of secondary education and subject choice with technically oriented aptitudes for automotive operators

Orientation: The central theme of this study attends to the role of secondary education in relation to two broad categories of specific aptitudes (psychomotor and spatial abilities). Utilising type of secondary education (incorporating subject choice) could be a crucial selection mechanism for high-volume, entry-level technical positions. Research purpose: The objective of this research was to investigate whether the type of secondary education (incorporating subject choice) could be used as a proxy for psychomotor (dexterity and coordination) and/or spatial (ability to mentally assemble representations and spatial perception 2-D and 3-D) aptitudes in the selection of operators for an automotive plant in South Africa. Motivation for the study: The motivation for this study arose from the evident gap in academic literature as well as the selection needs of the automotive industry. Research design, approach and method: A quantitative approach with a cross-sectional research design was used with a convenience sample ( n = 1566) of work-seeking applicants for automotive operator positions in South Africa. These applicants completed a biographical questionnaire and five sub-tests from the Trade Aptitude Test Battery. The Chi-square test was used to determine the association between form of Grade 12 qualification and selected technical aptitudes. Main findings: Statistically and practically significant relationships were found between type of secondary education (incorporating subject choice), eye–hand coordination and spatial visualisation. Broad performance levels in the five aptitude instruments employed in this study were significantly associated with the type of matriculation certificate held by applicants. Specifically, types of secondary education that included mathematics and/or science as subjects were associated with higher levels of performance in the five specific aptitudes. Practical/managerial implications: The type of secondary education (incorporating subject choice) held by applicants could be regarded as a key predictor variable in human resource selection. The study makes a case for a multiple-hurdles approach to selection and proposes a cost-effective preliminary screening method for low-level technical positions. Contribution/value-add: The study provides information to improve upon selection practices within the South African automotive industry. It could also assist human resource practitioners in designing selection processes for similar entry-level employees in other working contexts. The study makes a case for a multiple-hurdles approach to selection and highlights the reciprocal relationship between education and specific cognitive abilities in the science, technology, engineering and mathematics fields.
Vacuum energy density and pressure near a soft wall

Perfectly conducting boundaries, and their Dirichlet counterparts for quantum scalar fields, predict nonintegrable energy densities. A more realistic model with a finite ultraviolet cutoff yields two inconsistent values for the force on a curved or edged boundary (the "pressure anomaly"). A still more realistic, but still easily calculable, model replaces the hard wall by a power-law potential; because it involves no a posteriori modification of the formulas calculated from the theory, this model should be anomaly-free. Here we first set up the formalism and notation for the quantization of a scalar field in the background of a planar soft wall, and we approximate the reduced Green function in perturbative and WKB limits (the latter being appropriate when either the mode frequency or the depth into the wall is sufficiently large). Then we display numerical calculations of energy density and pressure for the region outside the wall, which show that the pressure anomaly does not occur there. Calculations inside the wall are postponed to later papers, which must tackle regularization and renormalization of divergences induced by the potential in the bulk region.
Management of Concomitant Medications With Romidepsin ( Istodax ® ) : Concerns and Recommendations Concomitant Medication Concerns Recommendations

Data Synthesis: Cardiac concerns during treatment with romidepsin are multifactorial. Electrolyte deficiencies, which are associated with ECG abnormalities and dysrhythmias, are common among patients with T-cell lymphoma. In addition, clinically insignificant changes in the corrected QT interval reported with romidepsin are primarily attributable to concomitant use of prophylactic antiemetics and likely exaggerated by transient increases in heart rate.
A MODEL OF CREATIVITY AND INNOVATION IN ORGANIZATIONS

As reported by Amabile et al. (1996:1154): “All innovation begins with creative ideas. We define innovation as the successful implementation of creative ideas within an organization. In this view, creativity by individuals and teams is a starting point for innovation; the first is a necessary but not sufficient condition for the second". As creativity is an important source of organizational innovation as well as competitive advantage (Amabile, 1988, 1996; Oldham & Cummings, 1996), organizations are increasingly seeking to foster it. Different managerial practices influence the work environment, which is one of the major factors impacting on creativity within business organizations (Couger, 1995). Therefore, managers face the challenge of creating the right context and conditions for creativity to flourish (Shalley, Gilson & Blum, 2000).
ranial morphological variation of Dromiciops gliroides Microbiotheria ) along its geographical distribution in south-central hile : A three-dimensional analysis

We analyzed the variation in cranial morphology of the marsupial Dromiciops gliroides along its distribution in south-central Chile. We evaluated whether the cranial morphological variation is congruent with the phylogeographic structure previously observed in this species. We built three-dimensional models of 69 crania on which we digitized 30 landmarks. We used standard geometric morphometric methods to extract and analyze the shape and size components of the crania. Our data showed a subtle but consistent cranial size and shape variation along the studied distributional range, suggesting a geographic variation pattern rather than a phylogeographic structuring. Indeed, our multivariate analyses recovered a subtle
Repeated jökulhlaups at Russell Glacier , Kangerlussuaq , West Greenland : a reappraisal of the jökulhlaup cycle concept

Two recent jökulhlaups from an ice-dammed lake on the northern margin of Russell Glacier in West Greenland mark the onset of a renewed jökulhlaup cycle after 20 years of stability. We present a novel record of successive ice-dammed lake (IDL) drainage events and associated ice margin dynamics spanning ~ 25 years, which is enabled via robust calculations of lake volumes and peak discharges based on intensive field surveys, and high spatial resolution orthophotographs of the lake basin and ice margin. These data enable the first field-based examination of controls on jökulhlaup magnitude and frequency for this system and provide a test of prevailing models relating fluctuations of glacier margin position to jökulhlaup cyclicity. Russell Glacier jökulhlaups have a much higher peak discharge than predicted by the Clague-Mathews relationship, due to an unusually short englacial/subglacial routeway and the presence of a thin ice dam that permits incomplete sealing of jökulhlaup conduits between lake drainages. We demonstrate that the passage of jökulhlaups through an inter-linked system of proglacial bedrock basins results in a significant attenuation of peak discharge downstream. Improved understanding of jökulhlaup dynamics requires accurate information about ice-dammed lake volume and ice-proximal jökulhlaup discharge. It is clear that larger ice-dammed lakes may prevent the direct runoff of significant volumes of meltwater over annual to decadal timescales. INTRODUCTION AND AIMS Glacier-dammed lakes exist worldwide and often pose an extreme hazard when they drain rapidly generating glacial outburst floods or ‘jökulhlaups’. Indeed mountain glacier margin recession and accompanying increases in meltwater production have resulted in the formation and destabilization of many ice-dammed lakes (e.g. Wiles and others, 2008). Whilst controls on the drainage of a
On the type Ia supernovae 2007on and 2011iv: evidence for Chandrasekhar-mass explosions at the faint end of the luminosity–width relationship

Radiative transfer models of two transitional type Ia supernovae (SNe Ia) have been produced using the abundance stratification technique. These two objects - designated SN 2007on and SN 2011iv - both exploded in the same galaxy, NGC1404, which allows for a direct comparison. SN 2007on synthesized 0.25M⊙of56Ni and was less luminous than SN 2011iv, which produced 0.31M⊙of56Ni. SN2007on had a lower central density (ρc) and higher explosion energy (Ekin~1.3 ± 0.3 × 1051erg) than SN 2011iv, and it produced less nuclear statistical equilibrium (NSE) elements (0.06M⊙). Whereas, SN2011iv had a larger ρc, which increased the electron capture rate in the lowest velocity regions, and produced 0.35M⊙of stable NSE elements. SN 2011iv had an explosion energy of ~Ekin~0.9 ± 0.2 × 1051erg. Both objects had an ejecta mass consistent with the Chandrasekhar mass (Ch-mass), and their observational properties are well described by predictions from delayed-detonation explosion models. Within this framework, comparison to the sub-luminous SN 1986G indicates SN 2011iv and SN 1986G have different transition densities (ρtr) but similar ρc. Whereas SN 1986G and SN 2007on had a similar ρtrbut different ρc. Finally, we examine the colour-stretch parameter sBVversus Lmaxrelation and determine that the bulk of SNe Ia (including the sub-luminous ones) are consistent with Ch-mass delayed-detonation explosions, where the main parameter driving the diversity is ρtr. We also find ρcto be driving the second-order scatter observed at the faint end of the luminosity-width relationship. © 2018 The Author(s).

A note on estimating a smooth monotone regression by combining kernel and density estimates

In a recent paper Dette, Neumeyer and Pilz (H. Dette, N. Neumeyer, and K.F. Pilz, A simple nonparametric estimator of a strictly monotone regression function, Bernoulli 12 (2006), pp. 469–490) proposed a new nonparametric estimate of a smooth monotone regression function. This method is based on a non-decreasing rearrangement of an arbitrary unconstrained nonparametric estimator. Under the assumption of a twice continuously differentiable regression function, the estimate is first-order asymptotic equivalent to the unconstrained estimate and other types of smooth monotone estimates. In this note, we provide a more refined asymptotic analysis of the monotone regression estimate. In the case where the regression function is increasing but only once continuously differentiable, we prove the asymptotic normality of an appropriately standardised version of the estimate, where the asymptotic variance is of order n −2/3−ϵ, the bias is of order n −1/3+ϵ and ϵ > 0 is small. Therefore, the rate of convergence of the new estimate is worse than the rate n −1/3 of the (unsmoothed) monotone least squares estimate. On the other hand, if the derivative of the regression function is Hölder continuous, the rate of convergence of the new estimate is faster than n −1/3.
Title Anxiety Impacts Cognitive Inhibition in Remitted Anorexia Nervosa Permalink

Objective: Eating disorders are complex psychiatric disorders, associated with alterations in neural and cognitive functioning. Research suggests inhibition and set-shifting deficits in anorexia nervosa (AN), but less is known about the persistence of these deficits after recovery, or their relationship to comorbid psychiatric symptoms. Method:Women aged 19–45 remitted from AN (RAN, N=47) and controls (CW, N=24) completed the Delis–Kaplan Executive Function System Color-Word Interference Test. It was hypothesized that RAN, and those with higher anxiety or depression, would demonstrate worse Inhibition and Switching task performance than CW. Results: Differences in performance between groups trended toward significance on Inhibition Ratio (p=0.08) but were nonsignificant on Inhibition/Switching Ratio (p=0.93). A model including State Anxiety and diagnosis revealed a significant independent effect of State Anxiety (p=0.026), but not of diagnosis nor their interaction. Regressing State Anxiety on Color-Word Interference Test Inhibition among just the RAN group was significant [β=0.37, t(46) = 2.63, p=0.012] but among just CW was not (p=0.54). Discussion: Interference control for neutral stimuli is influenced by anxiety in women with a history of AN. Anxiety is linked with greater symptom severity among AN individuals, and state anxiety may account for larger deficits seen on tasks using disorderspecific stimuli. Future research is warranted to elucidate the nature of neuropsychological deficits in eating disorders.

Possible effect of wheat germ oil or beta-carotene to enhance kidney recovery processes in irradiated rats

Radiation nephropathy has appeared as a substantial complication of radionuclide radiotherapy. Thus, the requirement for a protective agent against radiation injury is evident. The present study explored the potential effects of beta-carotene (βC) as well as, wheat germ oil (WGO) on gamma-irradiation resulted in oxidative stress and renal nephropathy in rats. Rats were divided into six groups: normal control group, βC group, WGO group, irradiated (IRR) group, βC+IRR group, WGO +IRR group. Oral administration of βC (10 mg /kg) or WGO (80 mg/kg) for 7 days after γ-irradiation (7.5 Gy) have significantly minimized the severity of biochemical changes, which was evidenced by a significant diminution in the level of malondaldhyde (MDA) in kidney, urea, creatinine as well as C-reactive protein (CRP) along with an increase in Glutathione (GSH) level, superoxide dismutase activity (SOD), urea and creatinine clearance comparing to the corresponding values of irradiated rats (P < 0.05). Histopathological examination of kidney tissues further confirms the biochemical records. Therefore, it is concluded that, βC as well as, WGO may reduce radiation nephropathy and enhance recovery processes after radiation exposure.
Galactic Center gamma-ray excess from two-Higgs-doublet-portal dark matter

We consider a simple extension of the type-II two-Higgs-doublet model by introducing a real scalar as a candidate for dark matter in the present Universe. The main annihilation mode of the dark matter particle with a mass of around $31-40$ GeV is into a $b\bar{b}$ pair, and this annihilation mode suitably explains the observed excess of the gamma-ray flux from the Galactic Center. We identify the parameter region of the model that can fit the gamma-ray excess and satisfy phenomenological constraints, such as the observed dark matter relic density and the null results of direct dark matter search experiments. Most of the parameter region is found to be within the search reach of future direct dark matter detection experiments.
