Assessment of antioxidant potential of Moringa stenopetala leaf extract

This study was conducted to assess the antioxidant potential of Moringa stenopetala leaf obtained from a private garden in Bahir Dar City and powdered Moringa leaf purchased from a supermarket in Bahir Dar City by using ferric reducing antioxidant power, 2,2-diphenyl-1-picrylhydrazyl radical scavenging capacity, peroxide value and conjugated diene hydroperoxide assays. The powdered Moringa stenopetala leaf extract was invariably found to have a higher antioxidant capacity than the purchased Moringa powder. In the conjugated diene hydroperoxide and peroxide value assays, sunflower oil was used as an oxidation substrate. Both peroxide value and conjugated diene concentration for sunflower oil containing extracts of Moringa leaf and purchased Moringa powder were found to be lower than the corresponding values observed for the control showing the effectiveness of the extracts in delaying oxidation of the oil. The total phenolic content, in terms of mg gallic acid equivalent per 100 g of dry weight of sample was found to be 92.8 ±1.01 and 75.5 ± 2.28 for, respectively, powdered leaves of M. stenopetala and purchased powder of Moringa leaf. The antioxidant capacity of the powdered Moringa stenopetala leaf and purchased Moringa powder were found to be, respectively, 442.0±10.58 and 291.3±15.52 mg of ascorbic acid equivalent per 100 g of dry weight of plant sample in the FRAP assay. The corresponding values for the powdered Moringa stenopetala leaf and purchased Moringa powder in the DPPH assay were found to be, respectively, 144.0±0.53, 138.8±1.05 mg of ascorbic acid equivalent per 100 g of dry weight of the sample. This difference in antioxidant capacity of these two samples can be attributed to differences in their total phenolic content. It is suggested that this antioxidant potential of the leaves of Moringa stenopetala may underlie the widespread use of the plant in traditional medicine. Key words : Moringa stenopetala , Antioxidant potential, Ferric reducing antioxidant power (FRAP), 2,2-diphenyl- 1-picrylhydrazyl (DPPH) radical, Folin-Ciocalteu’s phenol reagent (FCR), Peroxide value (PV).
Joint estimation of genetic parameters for daily recorded milk yield and body weight in first lactation Holstein cows.

The objective of the study was to jointly estimate the genetic parameters for daily recorded milk production (MY24) and body weight (BW) in first lactation Holstein cows. A total of 329,334 MY24 and BW phenotypes recorded from day in milk (DIM) 1 to 335 on 2,207 primiparous Holstein cows, calving from October 2013 to April 2017, were analyzed. The data came from 36 commercial dairy farms equipped with milking robots with automatic weighing platform, members of the Bretagne Conseil Elevage Ouest network. The variance components, heritability and genetic correlations for MY24 and BW were estimated using a bi-variate random regression test day model, where additive genetic and permanent environmental effects for the lactation and body weight curves were modeled using orthogonal Legendre polynomials of the second and fifth orders, respectively. The heritability for MY24 increased from 0.02 to 0.26 from DIM 1 to DIM 300, and then decreased. The heritability for BW increased from 0.26 (DIM 1) to 0.42 (DIM 100), remained quite stable until DIM 322, and then declined. The genetic correlations between BW and MY24 were positive. They were very low (<0.20) in early lactation, but larger after DIM15. This preliminary study will be repeated on a larger dataset and extended to multiparous cows, to evaluate the possibility of uncoupling body mobilization in early lactation from milk production.
Stellar Oscillations in Giant Stars

Walker et al. (1989) were the first to establish, using precise stellar radial velocity measurements, that K giant stars were a new class of variables. The variability of some of these stars can be quite complex showing several periods ranging from several hours to several hundreds of days. The long-period variations result from sub-stellar companions or rotational modulation, but the short-period variability certainly arises from stellar oscillations. We present recent of precise stellar radial velocity measurements (σ ≈ 6m s −1 ) of two oscillating K giant stars: β Oph and γ Dra. These stars show oscillation periods of hours (β Oph) and days (γ Dra). These periods are consistent with solar-like stellar oscillations, given the stellar properties of the star. Radial modes are a prime candidate for the type of oscillations in these stars.
THE EXPERIENCE OF POWER OR POWERLESSNESS AND MEMORY FOR OWN AND OTHER RACE FACES

EXPERIENCING POWER OR POWERLESSNESS AND MEMORY FOR OWN AND OTHER RACE FACES by Donald F. Sacco Jr. Research exploring the Cross Race Effect (CRE) indicates that individuals show better recognition accuracy for same-race faces compared to cross-race faces (Malpass, 1981), an effect thought to be due to a reduction in motivation to individuate cross-race faces (Hugenberg, Miller, & Claypool, 2007). Furthermore, research indicates that power reduces the motivation to individuate others while powerlessness increases the motivation to individuate others (Stevens & Fiske, 2000). Combining these research domains, the current study primed participants with either high or low power and had them complete a traditional CRE recognition task. The results indicated that compared to control participants, individuals primed with low power showed a larger CRE effect. High power participants, however, did not differ from control participants. Furthermore, the effect power on the CRE was not related to participants’ information processing style, which did not vary by power condition.

An Empirical Analysis of the Roles of Risk Aversion in the Automobile Insurance Market

This paper investigates the roles of risk aversion in the automobile insurance market to provide a possible explanation for the recent empirical findings that little or no evidence of asymmetric information is found in this market. Using more than 10,000 individual data set, we calculate the level of risk aversion from the choice of insurance contract under the constant absolute risk aversion assumption, and then examine the relationship between (i) risk aversion and insurance coverage purchased, and (ii) risk aversion and risk propensity. We find that risk tolerant drivers are less likely to choose broader coverage contracts and are more likely to incur accidents.
Graph-based Data Integration in EUDAT Data Infrastructure

European Data Infrastructure (EUDAT) is a distributed research infrastructure offering generic data management services to the research communities. The services deal with different phases of the data life cycle, some of them are tailored to account for special needs of the individual communities or replicated to increase the availability and resilience. All that leads to scattering of the large and heterogeneous data across service landscape limiting discoverability, openness, and data reuse. In this paper, we show how graph database technology can be leveraged to integrated the data across service boundaries. Such an integration will facilitate better cooperation among the researchers, improve searching and increase the openness of the infrastructure. We report on our work in progress, to show how better user experience and enhancement of the services can be achieved by using graph algorithms.

Effect of aspartame on some oxidative stress parameters in liver and kidney of rats

Aspartame is one of the most widely used artificial sweeteners in over 90 countries worldwide. It is a highly intensity sweetener added to a large variety of food, most commonly found in low calorie beverages, desserts and table top sweeteners added to tea or coffee. The present study examined whether the daily oral administration of ASP (40 mg/kg) for 2, 4 and 6 weeks induce oxidative stress in the liver and kidney of male albino rats. Lipid peroxidation (LPO), glutathione reduced (GSH) levels as well as the activities of superoxide dismutase (SOD), glutathione-S-transferase (GST) and catalase (CAT) enzymes were determined. A significant increase in LPO levels was obtained in the liver tissue after 4 and 6 weeks of ASP administration while there was a significant decrease in LPO level after 2 weeks followed by a significant increase in the renal tissue at the end of the 6 weeks. SOD activity significantly decreased in the liver tissue after 2, 4 and 6 weeks of treatment. Also, there was a significant decrease in SOD activity after 2 and 4 weeks in the renal tissue. CAT activity significantly decreased in the liver tissue after 2 and 4 weeks of ASP administration. Regarding to GSH content, there was a significant decrease in the liver tissue after 2, 4 and 6 weeks which was accompanied by a significant increase in GST activity after 4 and 6 weeks of ASP administration. In conclusion, ASP may induce an oxidative stress in the liver and kidney of male albino rats. Key words: Aspartame, oxidative stress, liver, kidney.
Information-Gathering Strategies in Behavioral Assessment

Summary: In behavioral assessment, the strategy theoretically most coherent for case formulation is to carry out a functional analysis aimed at discovering, among other factors, functionally relevant stimuli acting upon the problem-behavior. However, little is known about the decision-making processes involved in this task. Although many authors have suggested prescriptive models for this process, the strategies used by clinicians when gathering information seem to be left to experience and common sense. The present research is an attempt to increase the knowledge about this process of information gathering. The study was carried out with psychology students in their final year who already had enough theoretical knowledge to gather this kind of information, but still lacked practical experience. Subjects were asked to gather information aimed at checking a hypothesis about the functional role on a given behavior of either an antecedent or a subsequent (i.e., reinforcing) stimulus. The results show that in.
Rejection Sensitivity as Mediator Between Stigma and Romantic Relationship Satisfaction

HIV/AIDS is a highly stigmatizing condition that dramatically influences the social relations of those infected with the disease (Herek & Glunt, 1988; Kalichman, 2000). Stigmatized individuals experience interpersonal rejection because of their stigma and this rejection can heighten dispositional sensitivity to rejection (Downey & Feldman, 1996). Increased sensitivity to interpersonal rejection has been shown to decrease relationship satisfaction and lead to relationship dissolution (Downey, Freitas, Michaelis, & Khouri, 1998). Few studies have examined the influence of stigmatization on romantic relationships and little is known about the romantic relationships of people living with HIV/AIDS. The current study examined the role of rejection sensitivity as a mediator in the association between HIV/AIDS stigma and romantic relationship satisfaction. A diverse sample of HIV-positive participants was recruited from Vermont and neighboring states. Participants completed measures of perceived stigma, rejection sensitivity and satisfaction with their current romantic relationship. Disclosure concerns and enacted, or personalized, stigma predicted decreased relationship satisfaction. Rejection sensitivity did not mediate the relationship between stigma and relationship satisfaction. Results suggest that both rejection sensitivity and perceived stigma independently influence relationship satisfaction. The implications of the influence of stigma on romantic relationships are discussed.
Numerical and experimental study of the time-dependent states and the slow dynamics in a von Kármán swirling flow

The characteristics of time-dependent swirling flows in a von Kármán configuration are investigated numerically up to Reynolds number Re = 3000 (based on the angular velocity and the radius of the cylinder), and experimentally within turbulent regimes. Experimental results are analyzed together with the periodic and aperiodic flow obtained numerically. In the present configuration, the fluid is contained in a cylindrical cavity with aspect ratio (height to radius) Γ = 2 and the motion is driven by the exact counter rotation of the end walls while the sidewall is at rest. Spectral direct numerical simulations show that for this geometry the axisymmetric base flow becomes unstable to non-axisymmetric perturbations with azimuthal wavenumber m = 1 through a subcritical bifurcation, and the corresponding flow exhibits a pattern with one cat's eye in the axial-azimuthal planes. Increasing the Reynolds number the flow becomes unstable to non-axisymmetric steady perturbations with even azimuthal wavenumbers, and the corresponding flows exhibits a two cat's eyes pattern. The occurrence of cat's eye pattern in radial-azimuthal surfaces was observed in this and other aspect ratio cavities and is associated with vortices in 3D steady flows with characteristic azimuthal modes [Nore, C. , Tuckerman, L.S. , Daube, O. and Xin, S. , The 1 : 2 mode interaction in exactly counter-rotating von Kármán swirling flow, J. Fluid Mech. , 2003, 477, 51–88; Lackey, T.C. and Sotiropoulos, F. , Relationship between stirring rate and Reynolds number in the chaotically advected steady flow in a container with exactly counter-rotating lids, Phys. Fluids, 2006, 18, 1–14]. Time-dependent regimes are obtained numerically when the value of the Reynolds number is Re ≥ 1500. The time dependency is associated with a pulsation of the two vortices found in the steady regime. Experimental visualizations and measurements show that in turbulent regimes the flow also exhibits two vortices, but in this case they travel in the azimuthal direction with a frequency compatible with the frequency obtained in the numerical simulations at much lower Reynolds number. The azimuthal drift of these vortices is associated with the asymmetry of the mean azimuthal flow with respect to the equatorial plane.
OUTFLOWS IN SODIUM EXCESS OBJECTS

Van Dokkum and Conroy revisited the unexpectedly strong Na i lines at 8200 Å found in some giant elliptical galaxies and interpreted them as evidence for an unusually bottom-heavy initial mass function. Jeong et al. later found a large population of galaxies showing equally extraordinary Na D doublet absorption lines at 5900 Å (Na D excess objects: NEOs) and showed that their origins can be different for different types of galaxies. While a Na D excess seems to be related to the interstellar medium (ISM) in late-type galaxies, smooth-looking early-type NEOs show little or no dust extinction and hence no compelling signs of ISM contributions. To further test this finding, we measured the Doppler components in the Na D lines. We hypothesized that the ISM would have a better (albeit not definite) chance of showing a blueshift Doppler departure from the bulk of the stellar population due to outflow caused by either star formation or AGN activities. Many of the late-type NEOs clearly show blueshift in their Na D lines, which is consistent with the former interpretation that the Na D excess found in them is related to gas outflow caused by star formation. On the contrary, smooth-looking early-type NEOs do not show any notable Doppler components, which is also consistent with the interpretation of Jeong et al. that the Na D excess in early-type NEOs is likely not related to ISM activities but is purely stellar in origin.
Revival of Rural PDS: Expansion and Outreach

Using the recent rounds of NSS data, this paper evaluates the performance and outreach of India's public distribution system (PDS) in the rural areas. The results suggest a significant improvement in the performance of PDS in terms of its outreach and offtake. States like Bihar and Jharkhand which were lagging behind earlier have shown a marked improvement. [IGIDR WP-2014-012].
Individual and Organizational Factors of Safe Behaviour among Ghanaian Industrial Workers

The aim of this study is to compare individual and organizational factors as predictors of accident frequency. Four hypotheses based on the literature were presented: 1) both individual and organizational factors contribute to accident frequency, 2) individual factors have more impact than organizational factors, 3) both Organizational citizenship behaviour and Perceived organizational support are positively associated with safety behaviour, and 4) among the four organizational factors, Perceived organisational support has the most impact. The participants were 320 Ghanaian industrial workers from textile factories, breweries and mines. Organizational safety climate was measured using the 50-item Workplace Safety Scale. Organizational citizenship behaviour, Perceived organizational support and job satisfaction were measured by standardised scales. Individual factors were gender, age, education, marital status and job tenure. The respondents reported their accidents during the past 12 months. Models were tested using Structural Equation Modelling: Both individual and organizational factors contributed to accident frequency supporting hypothesis 1. Hypothesis 2 was rejected as organizational factors were more strongly related to accident frequency than individual factors. Organizational citizenship behaviour and Perceived organizational support were positively associated with safety performances as Hypothesis 3 suggested. In line with Hypothesis 4 the strongest predictor of safety behaviour was Perceived organizational support. This study showed that both individual and organizational factors are contributory for accident process. However, the influence of organizational factors was stronger than that of individual factors. Implications for safety in Ghanaian organizations were discussed.
Oxygen abundances in G- and F-type stars from HARPS

We present a detailed and uniform study of oxygen abundance from two different oxygen lines at 6158$\AA$ and 6300$\AA$ in a large sample of solar-type stars. The results are used to check the behaviour of these spectral lines as oxygen abundance indicators and to study the evolution of oxygen in thick and thin disk populations of the Galaxy. Equivalent width measurements were carried out for the [OI]~6158$\AA$ and OI~6300$\AA$ lines. LTE abundances were obtained from these two lines in 610 and 535 stars, respectively. We were able to measure oxygen abundance from both indicators in 447 stars, enabling us, for the first time, to compare them in a uniform way. Careful error analysis has been performed. We found that oxygen abundances derived from the 6158$\AA$ and 6300$\AA$ lines agree to within 0.1dex in 58\% of the stars in our sample, and this result improves for higher signal-to-noise values. We confirm an oxygen enhancement in stars of the thick disk, as has also been seen for other $\alpha$-elements. The new oxygen abundances confirm previous findings for a progressive linear rise in the oxygen-to-iron ratio with a slope equal to 0.78 from solar metallicity to [Fe/H]$\sim$-1. However, the slope we measured is steeper than the one found in previous studies based on the oxygen triplet. Below [Fe/H]=$-$0.6 our stars show [O/Fe] ratios as high as $\sim$0.8, which can be interpreted as evidence for oxygen overproduction in the Galactic thick disk. These high oxygen abundances do not pose a problem to chemodynamical models since there is a range of parameters that can accommodate our results.
Finding self in literary fiction

This study investigates the role of literary fiction and in particular the Bildungsroman for narrative identity construction. It emphasizes the consumption of its fans, as one can say that they are the most devoted consumers. The results of in-depth interviews with 10 international respondents demonstrate that the consumption of the Bildungsroman by its fans is a form of narrative practices. The consumption of the Bildungsroman as a form of narrative practices is based on three integral concepts. The first implies embodied reading (a potential subcategory of embodied cultural capital), which refers to potential effects of experiencing literary fiction. The second concept is the narratable self, which emphasizes the idea that one cannot narrate the self just individually, but that we also need the other in order to get a full image of who we are and what we can be. The third concept is narrative identity construction, which in this case entails the construction of the self, (partly) based on the subjective experience of fiction. In other words, this study demonstrates that the consumption of fiction has potential effects on narrative identity construction.
Genotyping and Drug Resistance Patterns of M. tuberculosis in Eastern Amhara region, Ethiopia

Background: Ethiopia is among the countries with the highest incidence of tuberculosis (TB) and has a early incidence of 379 cases/100,000 population. Of the high TB burden regions, Amhara is the top. So understanding the epidemiology of TB through molecular genotyping techniques such as Spoligotyping have invaluable role to combat TB. It will help to designing appropriate intervention and strengthen TB control program. Objectives: To provide insight about the genetic biodiversity of Mycobacterium tuberculosis, strain specific drug susceptibility and possible associated factors in Eastern Amhara region, Ethiopia. Methods: A facility based cross sectional study was conducted among smear positive TB patients (age ≥ 18 years old) from September 2011 to June 2012. Smear positive sputum samples were processed and decontaminated by the modified Petrof method. Primary isolation and drug susceptibility testing (DST) were carried out on egg based Lowenstein-Jensen (LJ). Genotyping of mycobacterial DNA was performed by spoligotyping and isolates were assigned to families using the SpolDB4 and the model-based program ‘Spotclust’. P-values less than 0.05 were considered as statistically significant. Result: The predominant Mycobacterium tuberculosis strains in the present study were ST 149/T3-ETH 49(22.6%), ST53/T1 18(8.3%) and ST50/H3 16(7.4%). T3-ETH strain showed the highest MDR-TB cases. Conclusion: Our finding suggests that a diversity of Mycobacterium tuberculosis strains accompanied with high rate of drug resistance.
