The GALAH survey: stellar streams and how stellar velocity distributions vary with Galactic longitude, hemisphere, and metallicity

Using GALAH (GALactic Archaeology with HERMES) survey data of nearby stars, we look at how structure in the planar (u, v) velocity distribution depends on metallicity and on viewing direction within the Galaxy. In nearby stars with distance d ≲ 1 kpc, the Hercules stream is most strongly seen in higher metallicity stars [Fe/H] > 0.2. The Hercules stream peak v value depends on viewed galactic longitude, which we interpret as due to the gap between the stellar stream and more circular orbits being associated with a specific angular momentum value of about 1640 km s-1 kpc. The association of the gap with a particular angular momentum value supports a bar resonant model for the Hercules stream. Moving groups previously identified in Hipparcos(HIgh Precision Parallax COllecting Satellite) observations are easiest to see in stars nearer than 250 pc, and their visibility and peak velocities in the velocity distributions depends on both viewing direction (galactic longitude and hemisphere) and metallicity. We infer that there is fine structure in local velocity distributions that varies over distances of a few hundred pc in the Galaxy.
Influence of primer mismatch and microdiversity on DGGE results: A case study with SAR11

Although SAR11 is usually the dominant bacterial group in most marine ecosystems when analyzed with clone libraries and fluorescence in situ hybridization, it is often not retrieved in studies where denaturing gradient gel electrophoresis (DGGE) has been used. We analyzed the microdiversity of SAR11 in Blanes Bay (NW Mediterranean) and we suggest that the high evenness of multiple microdiverse phylotypes, none of which being particularly dominant, is the probable rea- son for this methodological discrepancy. We used seeding experiments in which different amounts of 2 SAR11-affiliated clones were mixed with DNA from an environmental sample obtained from the Blanes Bay Microbial Observatory. Two primer sets differing at 2 base positions produced DGGE images that varied in their SAR11 detection threshold concentration. Our results show that primer mismatches and/or the presence of faint bands due to microdiversity could explain why SAR11 is frequently not retrieved from DGGE gels.
Pricing Determinants of selected Fixed Price IPOs issued in India

This paper is an attempt to examine the valuation factors affecting the pricing of Initial Public Offerings (IPOs) issued in India through fixed price mechanism and listed on BSE between 2010-2016. A total of 46 fixed Price IPOs were investigated for the impact of age of the company, revenue, net profits, net asset value per equity share, issue size, return on net worth, earnings per share, industry profits to earnings ratio and promoter’s shareholdings. The paper reveals that net asset value per share and net profits are positively correlated with both the offer price and listing price while issue size is negatively correlated with the offer price. Further the regression result also computed a significant impact of net asset value per share and net profits on the two pricing points.

Study on the Effect of Different Fe2O3/ZrO2 Ratio on the Properties of Silicate Glass Fibers

A series of silicate glass fibers with different ratios of Fe2O3/ZrO2 were prepared, and their corrosion resistance, mass loss, and strength loss were characterized. The crystallization and melting properties of the fibers were analyzed by differential scanning calorimetry (DSC), high temperature viscometer, and high temperature microscope. The results show that the deformation temperature, sphere temperature, hemisphere temperature, and crystallization temperature of the fiber initially decrease and then increase with the increase of Fe2O3/ZrO2 ratio, while the molding temperature decreases with the increase of the ratio of Fe2O3/ZrO2. When the ratio is close to 1 : 1, its alkali resistance is almost same as that of AR-glass fiber, and the drawing process performance is better. However, with the increase of the ratio, its alkali resistance continues to decline and the poor wire drawing performance is not conducive to the drawing operation.
Nonprice Competition in the Turkish Credit Card Market

Attempts to explain high and sticky credit card rates have given rise to a vast literature on credit card markets. This article endeavors to explain the rates in the Turkish market using measures of nonprice competition. In this market, issuers compete monopolistically by differentiating their credit card products. The fact that consumers perceive credit cards and all other banking services as a bundle allows banks to also employ bank level characteristics to differentiate their credit cards. Thus, the features and service quality of banks are expected to affect credit card rates. Panel data estimations also control for various costs associated with credit card lending. The results show that nonprice competition variables have significant and robust effects on credit card rates.
Efficiency of SSR, ISSR and RAPD markers in molecular characterization of mungbean and other Vigna species

Genetic diversity among 35 Vigna genotypes was assessed using SSR, ISSR and RAPD markers. SSR (21), ISSR (17) and RAPD (25) markers produced a total of 319 bands, of which 284 exhibited polymorphism. Higher marker indices were obtained for ISSR markers, which also proved to be the most efficient marker system in terms of average heterozygosity values. All the marker systems characterized the genotypes effectively. The similarity coefficients were significant for all the three marker systems, but were lower for SSR compared to ISSR and RAPD markers. The pooled allelic diversity data grouped 35 genotypes into 4 major clusters with most of the genotypes reflecting relationship according to the species distribution. The DNA based markers used in the present study were efficient in discriminating the studied Vigna species.
Crystal structure and docking studies of hexahydrocycloocta[b]pyridine-3-carbonitriles

The crystal structures of two new isomorphous pyridine structures, 2-ethoxy-4-(2-flurophenyl)-5,6,7,8,9,10-hexahydrocycloocta[b]pyridine-3-carbonitrile (Ia) and 2-methoxy-4-(4-isopropylphenyl)-5,6,7,8,9,10-hexahydrocycloocta[b]pyridine-3-carbonitrile (Ib) were elucidated by single crystal X ray diffraction. Compound (Ia) C 20 H 21 FN 2 O, crystallizes in the monoclinic system, space group P2 1 /n with a = 7.0738 (3) A, b = 17.3519(8) A, c = 14.4239 (7) A, b = 91.837 (2)° and Z = 4. The compound (Ib), C 22 H 25 N 2 O, crystallizes in the same crystal system as compound (Ib), space group P2 1 /c with a = 9.7123(6) A, b = 20.6046(9) A, c = 10.4657(6) A, b = 117.208 (3)° and Z = 4. The central heterocyclic ring adopts a planar conformation and the cyclooctane ring adopts a twisted boat chair conformation in both (Ia) and (Ib). The synthesized compounds were screened for their anti-tuberculosis activity and were used to identify lead structures through docking studies, by automated docking. This approach was used to determine the orientation of inhibitors bound in the active site with the enzyme N-acetyl-gamma-glutamyl-phosphate reductase that is involved in arginine biosynthesis in M. tuberculosis (MtbAGPR). Details of the preparation, crystal structure determination, intra and inter molecular interactions of the compounds and their docking studies are given.
Social Evaluations in a Multiple-Audience Context : The Impact of a Social Misconduct on People's Complaints, Share Price and Media Evaluation

Literature on social evaluations has mainly analyzed the “audience-candidate” dyad,leaving underexplored the way the evaluation of a main audience (e.g. a social-control agent)influences the evaluation of another audience. This dissertation looks at social evaluations in amultiple-audience context. It focuses on organizational social misconduct - an important, yetunderstudied social evaluation - and it investigates “Why does an audience change its evaluationfollowing organizational social misconduct? ”. Each of the three essays focuses on a differentaudience (evaluation): people (people’s complaints), investors (share price) and the media(newspapers’ evaluation). Two novel settings and unique databases were used: advertising selfregulationin the UK and Calciopoli, the scandal that affected the Italian Serie A in 2006. Resultsshow that in case of organizational social misconduct, the evaluation of a social control agent doesinfluence the evaluation of another audience, however this effect is not mechanical. Three primarymoderators emerge from the three essays: the ambiguity of the norm, the saliency of the event, andlocalness of the transgressors. In summary, this dissertation shows that social norms are betterunderstood in a triadic framework: “candidate – social-control agent – another audience”. Socialnorms are not set exogenously, but are endogenously created by the actions of the candidates andthe evaluations of (at least) two audiences.
Influence of blade aerodynamic model on prediction of helicopter rotor aeroacoustic signatures

Brown’s vorticity transport model has been used to investigate how the local blade aerodynamic model influences the quality of the prediction of the high-frequency airloads associated with blade–vortex interactions, and thus the accuracy with which the acoustic signature of a helicopter rotor can be predicted. The vorticity transport model can accurately resolve the structure of the wake of the rotor and allows significant flexibility in the way that the blade loading can be represented. The Second Higher-Harmonic Control Aeroacoustics Rotor Test was initiated to provide experimental insight into the acoustic signature of a rotor in cases of strong blade–vortex interaction. Predictions of two models for the local blade aerodynamics are compared with the test data. A marked improvement in accuracy of the predicted high-frequency airloads and acoustic signature is obtained when a lifting-chord model for the blade aerodynamics is used instead of a lifting-line-type approach. Errors in the amplitude and phase of the acoustic peaks are reduced, and the quality of the prediction is affected to a lesser extent by the computational resolution of the wake, with the lifting-chord model producing the best representation of the distribution of sound pressure below the rotor.
Plant regeneration studies of Jatropha curcas using induced embryogenic callus from cotyledon explants

A plant regeneration system for Jatropha curcas , a biofuel- producing plant, was established from the induced embryogenic callus. Cotyledon explants cultured on single auxin media were able to form callus. However, only the callus induced from cotyledon explants using Murashige and Skoog (MS) medium containing 0.8 mg l -1 dicamba was embryogenic. The somatic embryos were suitable to be proliferated using phytohormone- free woody plant medium (WPM). Two somatic embryo regeneration methods were studied and the direct somatic embryos plant regeneration method using the media containing 0.3 mg l -1 6-benzylaminopurine (BAP) and 0.4 mg l -1 gibberellic acid (GA 3 ) was more effective, 83.3 and 73.33% plant regeneration, respectively. The other method that needed to mature the somatic embryos prior to plant regeneration from the phytohormone- free MS medium was not preferred, less than 40% plant regeneration. In conclusion, an efficient plant regeneration system for J. curcas was established through somatic embryogenesis. Keywords: Jatropha curcas , cotyledons, callus , somatic embryogenesis , plant regeneration
PERFORMANCE OF BROILER CHICKENS UNDER VARIOUS STRESS CONDITIONS

The performance of birds reared under recommended management (T1 and T2 controls) was compared with those reared under various stress conditions. The data on various parameters were analyzed in completely randomized design (CRD). Stress of overcrowding and poor litter conditions affected body weight gains during latter weeks of age from 4th week. Feed intake was significantly affected by overcrowding from 4th week onwards, by high light intensity from 2nd week onwards and poor litter condition from 4th week onwards as compared to control birds. Feed Conversion Ratio (FCR) under stress of poor feeding was significantly inferior from 2nd week onwards. FCR was not affected significantly either by high light intensity or by poor litter conditions.
The Effect of Genetic Background on the In Vitro Development of Mouse Embryos in Potassium Simplex Optimized Medium Supplemented with Amino Acids (KSOMAA)

In vitro culture systems are required for many biotechnological and assisted reproductive technologies. In order to perfect the conditions, the effect of genetic background was evaluated in the in vitro development of embryos from CD-1 and CB6F1 mice in potassium simplex optimized medium supplemented with amino acids (KSOM AA ). Presumptive zygotes were recovered from superovulated and mated females (19-20 h post-hCG injection). Two-cell stage block, morula (M), expanded blastocyst (EB), and completely hatched blastocyst (CHB) rates and total cell count were compared in the two mouse strains. The development of CD-1 vs. CB6F1 embryos to 2-cell (98% vs. 96%) and to 3- to 8-cell (89% vs. 93%, respectively) were not significantly different (p > 0.05). However, significant differences were detected in the proportions of CD-1 vs. CB6F1 embryos reaching later stages (79% vs. 91% for M (p < 0.01), 65% vs. 77% for EB (p < 0.05), and 34% vs. 49% for CHB stages (p < 0.01), respectively). The results showed that the genetic background of mouse embryos has a significant effect on in vitro developmental potential to late pre- implantation stages. Nevertheless, zygotes obtained both from CB6F1and CD-1 mouse strains have been cultured successfully in KSOM AA in 5% CO2 in air at 37 iC.

Competition and cost pass-through in differentiated oligopolies

The impact that competition exerts on the incentives of firms to pass through reductions in their marginal costs is an important consideration in assessing the performance of alternate market structures. This paper examines the role of product differentiation on firm-specific and industry-wide pass-through rates. Relying on Shubik’s (1980) model of differentiated Cournot competition with linear demand, we show that there exists an initial critical range over which the firm-specific cost pass-through rate decreases in the number of firms. Beyond this range the rate continually increases – approaching 50 percent as the number of firms goes to infinity. This contrasts with a model of differentiated Bertrand competition in which cost pass through monotonically decreases in the number of firms. The disparate effects across the Cournot and Bertrand models are shown to stem from the influence of competition and product differentiation on the respective firm reaction functions. Suggestions for future empirical work based upon the models’ predictions and implications for antitrust policy are also discussed.
Temperature sensitivity analysis of thermal comfort in a UK residential building

This research focusses on investigating the sensitivity of thermal comfort to temperature in a heated space. Thermal comfort test sessions are conducted in a test house representative of a typical UK house during the winter season. A total of 119 participants took part in the series of tests conducted in the test house’s living room. Operative temperature in the heated space was maintained within the comfortable range recommended by CIBSE for a living room area in a UK house. Two different heating emitters were used for heating during the tests in order to examine their effects on occupant thermal comfort. Conventional radiators supplemented by a gas boiler and an electric fan heater were investigated in the presence and absence of a circulation fan running in the corner of the room. Thermal comfort sensation of occupants was calculated using sensors installed in the living room (Fanger’s Predicted Mean Vote). At the same time the occupants were asked to fill in surveys which were used to record their Actual Mean Vote. From the test sessions conducted it was found that AMV predicted a neutral temperature of 23.5°C whilst PMV predicted a neutral temperature of 24.0°C thus PMV over predicted the occupant’s thermal sensation compared to AMV. For the four heating scenarios it was found that a convective fan heater with a circulation fan causes the smallest temperature gradient (1.0oC) between ankle and head height for a seated occupant according to ISO7730 standards. The highest temperature gradient was measured for fan heater without a circulation fan (7.3oC). Occupants reported to be most uncomfortable if the convector heater without a circulation fan was used.
Gaining Balance: Toward a Grounded Theory of the Decision- Making Processes of Applicants for Adoption of Children with and without Disabilities

A grounded theory is presented of the decision-making processes among applicants when considering available children with and without disabilities for domestic public adoption. Using grounded theory methodology (Strauss & Corbin, 1998), data from 15 adoption applicants were analyzed followed the traditional three coding phases. The central category of Adoption Decision Making is labeled Gaining Balance and was the underpinning concept to all categories and sub-categories (i.e., in parentheses) of the theory: Commitment (e.g., motivation, financial considerations), Persistence (e.g., coping with emotions, counteracting pessimism), and Evaluation (e.g., assessments of personal abilities and resources, assessments of knowledge of potential adoptees’ needs). The results are compared to existing literature and implications for child
Public Perceptions on Location of Filling Stations in the City of Kitwe in Zambia

Location of manufacturing and service activities in urban areas are guided by planning principles and standards, expressed in either structure plans or land use development plans. Though Local authorities are the major overseers on the implementation of approved structure plans based on the advice of Urban Planners and consultants on environmental protection and sustainability, unfortunately, there appears to be sporadic emergence of filling stations within the City of Kitwe in Zambia that raises the questions, “What are the locational determinants for filling stations in urban areas in Zambia? ” What is the public’s perception on location of filling stations in the City of Kitwe? What are the possible factors that influence filling stations’ locations in Kitwe? Are filling stations located according to established planning standards, guidelines and regulations in the City of Kitwe? These are questions that require empirical investigations in view of the possible inflammatory consequences of the service. The paper is an exploratory study that applied a cross-sectional descriptive research design to find answers to the research questions and to validate the following hypotheses: Environmental Impact Assessment (EIA) Criteria is positively related to the location of filling stations in Kitwe; Entrepreneurs preferential location choices is positively related to location of filling stations; and Planning principles, standards and regulations positively influence locations of filling stations in the City of Kitwe. The t-test statistics was used to validate the hypotheses. The main finding was that, filling stations are located influenced by choices made by service station entrepreneurs. Keywords: Public Perceptions, filling stations, location, planning standards, Kitwe
Cymbopogon citratus (DC.) Stapf : chemical composition and biological activities

Cymbopogon citratus (DC.) Stapf is a perennial grass that grows spontaneously around the world, mainly in the tropical and savannah regions. Infusions of its leaves are used in traditional medicine as antimicrobial, anti-inflammatory and sedative. The leaf essential oil is used in the food, perfumery, soap, cosmetic, pharmaceutical and insecticide industries. The main constituents of the essential oil are citral (aldehydes geranial + neral) and terpenes (myrcene monoterpene and geranial terpenic alcohol). The comprehensive account of the chemical constituents and the biological activities are presented in this review to allow an evaluation of the potential use of this plant either in pharmaceutics or as an agricultural resource.
Oxidative Stability Of Palm Olein Added With Ethanol Extract Of Curry Leaves And Sensory Quality Of The Fried Product

In this study, curry leaves extract was used to minimize the oxidation process upon deep-fat frying. Crude extract was isolated from dried and ground curry leaves using ethanol and excess solvent was evaporated off. Three systems of frying oil; I) palm olein without curry leaves extract, II) palm olein with 0.02% curry leaves extract and III) palm olein with 0.04% curry leaves extract were prepared and fried repeatedly to 6 consecutive batches. Oil sample was collected at batches 2, 4 and 6 for analysis of iodine value (IV), peroxide value (PV), free fatty acid (FFA) content and thiobarbituric acid (TBA) value while the fries was kept for sensory quality assessment. Generally, the findings showed that system III was the most effective in retarding oil oxidation as compared to system I and II. This could be clearly observed in analysis of PV and IV, where system III gave the lowest rate of increment. Sensory attributes (yellow colour, hardness, oiliness, rancid smell, curry leaves aroma and overall quality) of the fried fries was found to have no significant (P>0.05) differences between all the systems indicating that the extract did not affect the sensory attributes evaluated.
