Fundamental parameters and granulation properties of Alpha Centauri A and B obtained from inversions of their spectra

Properties of stellar granulation are obtained by inverting spectra of the late-type stars α Centauri A and B. Our inversions are based on a multi-component model of the stellar photosphere and take into account the center-to-limb variation and rotational broadening. The different atmospheric components describe the areas harboring up-, down- and horizontal flows. The inversions are constrained by fitting not only the flux profiles, but also their line bisectors, and by using a simple mass conservation scheme. The inversions return the properties of convection at the stellar surface, including the stratification of the thermodynamic parameters, as well as fundamental parameters such as the gravitational acceleration, v sini and the element abundances. For α Cen A (G2V) the derived stratifications of the temperature and convective velocity are very similar to the Sun, while for α Cen B (K1V) we find similar up- and downflow velocities, but lower horizontal speeds and a reduced overshoot. The latter is consistent with the smaller scale height of the atmosphere, while mass conservation arguments taken with the lower horizontal speed imply that the granules on α Cen B are smaller than on the Sun. Both these properties are in good agreement with the hydrodynamic simulation of Nordlund & Dravins (1990, A&A, 228, 155). The inversions also return the fundamental parameters (Teff ,l ogg, abundances, v sini, etc.) of the two stars. These values are on the whole in good agreement with literature values. Also, most of them do not strongly depend on the details of the inversion. However, importantly, the element abundances are 0.1 to 0.15 dex lower when a 2- or 3-component inversion is carried out than with a 1-component inversion.
Synthesis and characterisation of imidazolium-based ionic liquid crystals bearing a cholesteryl mesogenic group

A series of cholesteryl-containing imidazolium chlorides and imidazolium tetrachloroaluminates were synthesised, and the chemical structure, liquid crystalline behaviour and ionic conductivity were characterised by several technical methods. Whereas the imidazolium chlorides show chiral smectic A (SmA*) phase on heating and cooling cycles, the imidazolium tetrachloroaluminates display chiral nematic (N*) phase, which is uncommon for ionic liquid crystals (ILCs). The imidazolium chlorides display similar phase transition temperature and entropy, indicating the cholesteryl component influence predominately on the phase transition rather than the different alkyl substituent groups. The imidazolium tetrachloroaluminates show lower melting point temperatures and lower clear point temperature than the imidazolium chlorides. The mesophases exist at rather moderate temperatures. Non-mesomorphic imidazolium tetrachloroaluminate(III) salts with short alkyl substituents have been known for a long time, and the synthesised imidazolium tetrachloroaluminates are the first examples of tetrahalogenoaluminate(III)-containing ILCs. For the imidazolium tetrachloroaluminates, imidazolium cations combine loosely with AlCl4− ions because AlCl4− ions are large and occupy more space in spite of the hydrogen bond and electrostatic attraction interaction, indicating that the layer structure can be destroyed easily to form N* phase on heating.
Effect of light intensity and photoperiod on growth and survival of the Mexican cichlid, Cichlasoma beani in culture conditions

Wild populations of the green mojarra Cichlasoma beani , are being pressured by anthropogenic activities. It is possible to mitigate the deterioration of native species populations by developing culture techniques. Environmental factors such as light intensity and photoperiod may affect the development of fish under culture conditions. Therefore, the aim of the present study was to examine the effect of these factors on growth, survival, and condition of C. beani cultured in different light intensities and photoperiods. Light intensities of 1000, 1500 and 2000 lux and photoperiod 24:00, 16:08 and 08:16 Light:Dark (L:D) were tested in 40 L tanks (10 fish per tank, three replicates per treatment) during eight weeks. There were no significant differences in light intensity or photoperiod, which was associated with the natural adaptation of the species to these factors. The results also suggested the favorable overall growing conditions during the trial and he response of the life cycle stage of the specimens used in this study. The results of the present study indicate that the natural adaptations of C. beani , allow the favorable culture in various light conditions in juveniles, which can be advantageous for commercial culture as may imply low energy costs.
Antibacterial Properties of Allopathic Drug Loaded Polycaprolactone Nanomembrane

Biodegradable polymer nanomembrane have high porosity with interconnected pores and high surface area-to-volume ratio that makes them ideal for wound dressing and drug delivery applications. In this study, biodegradable Polycaprolactone (PCL) nanomembrane and PCL Nanomembrane containing allopathic drug (Tetracycline hydrochloride) were successfully prepared by the electrospinning technique and nanomembranes were characterized using Scanning Electron Microscope (SEM), Capillary flow porometer and Fourier Transform Infrared Spectroscopy (FTIR). The antibacterial properties of nanomembrane were evaluated by AATCC 100-2004. The incorporation of allopathic drug in PCL nanomembrane did not influenced the morphology of the resulting fibers, as both the drug-free and the drug loaded nanomembrane remained unaltered, microscopically. Drug loaded PCL nanomembrane was able to inhibit the growth of the bacteria which indicate that it could act not only as a drug delivery system but also in the treatment of wound healing or dermal bacterial infections thereby proving a potential application for use as a wound dressing.
The effect of heat stress and the use of Saccharomyces cerevisiae or (and) bacitracin zinc against heat stress on the intestinal mucosa in quails

Cette etude a pour but de determiner, chez des cailles, l'effet du stress de chaleur et d'evaluer l'impact de l'utilisation de Saccharomyces cerevisiae ou (et) de bacitracine zinc contre ce stress sur la longueur etla largeur des villosites intestinales du duodenum, jejunum et ileum ainsi que sur le nombre de cellules en gobelet par unite. Pour cela, 47 cailles japonaises de 56 jours ont ete utilisees. La longueur et la largeur des villosites et le nombre de cellules en gobelet ont ete determines a l'aide d'un programme d'analyse d'image sur des coupes en serie des echantillons intestinaux. Ces analyses ont montre une diminution de la longueur des villosites au niveau duodenum, jejunum et ileon chez les cailles soumises au stress de chaleur ; de meme, le nombre de cellules en gobelet des villosites a considerablement diminue dans leur ileon alors que cette diminution n'etait pas significative au niveau du duodenum et du jejunum. Chez les animaux ayant recu les levures pour lutter contre le stress de chaleur, les longueurs de villosites sont diminuees dans le jejunum, alors que le nombre des cellules en gobelet avait augmente chez les animaux ayant recu la bacitracine zinc. Chez les animaux ayant recu conjointement les deux produits, la longueur des villosits a diminue dans le jejunum et l'ileum alors que le nombre de cellules en gobelet a augmente. Par consequent, ces deux produits semblent avoir un effet additif mais aucun effet synergique n'a pu etre mis en evidence.
Tax E-filing Adoption in Malaysia: A Conceptual Model

Tax e-filing is one of the e-government services that is gaining importance for public to perform their responsibility to the country through tax payment. Despite the rapid adoption of e-filing in Malaysia, the e-filing system is still unreliable especially at peak period which lead to high level of risk perceived by taxpayers. This paper proposes a framework that incorporates the significant affect of performance risk, which is a significant perceived risk facet, on tax e-filing adoption in Malaysia. In this paper, the framework also posits the perceived risk and performance risk within the Technology Acceptance Model (TAM) within the e-filing context. This model will serve as a useful guideline not only for devising strategies to promote e-government services, particularly tax e-filing service but also to improve the performance of the e-filing system.

Abstrak Penelitian ini dilakukan bertujuan untuk menguji apakah keputusan manajer untuk meneruskan proyek yang gagal dipengaruhi oleh prinsip moral. Prinsip moral diduga oleh Harrison et al. (2003) mempengaruhi asimetri informasi dan dorongan untuk melalaikan (incentive to shirk) oleh manajer dalam memutuskan diteruskan tidaknya suatu proyek. Dengan menggunakan sampel 53 mahasiswa STIE Widya Wiwaha Jogjakarta, hipotesis pertama yang menyatakan bahwa asimetri informasi dan incentive to shirk mempengaruhi keputusan kelangsungan proyek terbukti signifikan. Untuk hipotesis kedua, variable prinsip moral ternyata tidak mempengaruhi secara signifikan baik sebagai kovariat, variable independent maupun variable moderasi.
Expression profile of toll-like receptor mRNA in an indigenous aseel breed of chicken in India.

Expression profile of chicken six Toll-like Receptor (TLR) mRNAs were analyzed in the heterophils, lungs, liver, spleen, duodenum, caecal tonsils and kidneys of 12-weeks old indigenous village chicken in India, using reverse transcription polymerase chain reaction (RT-PCR). TLR 2 type 1 mRNA was expressed in lungs, liver, spleen, duodenum and caecal tonsils. TLR2 type 2 mRNA was expressed only in the lungs. TLR 3 mRNA was expressed in lungs, liver, spleen and caecal tonsils. TLR 4 mRNA was expressed only in lungs, liver and spleen. TLR 5 and TLR 7 mRNAs were expressed in all the tissues examined. With respect to tissues, heterophils and lungs expressed all the TLR mRNAs examined while kidneys expressed only TLR 5 and TLR 7 mRNAs. All the TLR amplified PCR products were partially sequenced and showed high homologies with the available chicken (commercial) TLR gene sequences. There could be a possibility of correlation between TLR mRNA expressions with higher levels of innate immunity seen in indigenous village breeds of chickens.

Using Performance Incentives to Improve Health Outcomes

This study examines the effect of performance incentives for health care providers to provide more and higher quality care in Rwanda on child health outcomes. The authors find that the incentives had a large and significant effect on the weight-for-age of children 0-11 months and on the height-for-age of children 24-49 months. They attribute this improvement to increases in the use and quality of prenatal and postnatal care. Consistent with theory, They find larger effects of incentives on services where monetary rewards and the marginal return to effort are higher. The also find that incentives reduced the gap between provider knowledge and practice of appropriate clinical procedures by 20 percent, implying a large gain in efficiency. Finally, they find evidence of a strong complementarity between performance incentives and provider skill.
Botanical Regulation: Comparison of the United States and Canada

Botanicals are defined as ingredients or finished products “of or relating to plants” or “a substance obtained from a plant. ” Botanicals have been used by humans since the beginning of civilization. Archaeological excavation documents the medicinal use of plants by humans dating back as far as 60,000 years [1]. Today about 80% of the world still uses plants and plant-based products to treat medical conditions [2].
A Market-Based Framework for Bankruptcy Prediction

We estimate probabilities of bankruptcy for 5,784 industrial firms in the period 1988-2002 in a model where common equity is viewed as a down-and-out barrier option on the firm's assets. Asset values and volatilities as well as firm-specific bankruptcy barriers are simultaneously backed out from the prices of traded equity. Implied barriers are significantly positive and monotonic in the firm's leverage and asset volatility. Our default probabilities outperform the ones inferred from a standard Black-Scholes/Merton and KMV frameworks, both in terms of discriminatory power and calibration. In particular, the possibility of early bankruptcy resolves some of the well-documented miscalibration. We also find that accounting-based measures such as Altman Z- and Z"-scores outperform structural models in one-year-ahead bankruptcy predictions, to fade away as the forecast horizon is extended.
Does 4G Technology Trigger the S-commerce Era Coming Evidence from Taiwanese ICT Market

In reviewing of the generalization of wireless technology in the variously relative information and communication technology (ICT) industries, this research systematically explore the potential determinants of the fourth generation (4G) technology to cross-analyze the drivers of the smart-commerce (S-commerce) era forthcoming through the comprehensive measurements of the hierarchical analytical network process (ANP) resulted from the multiple criteria decision making (MCDM) methodology by gathering of the Taiwanese ICT market surveyed data. The most contribution is that "the 4G technology probably trigger the Smartcommerce (S-commerce) era coming. (4GPYTSEC)" that means the S-commerce is still the developed mainstream in the variously relative ICT industries according to the some restricted factors, such as technological development limitation, government political prohibition, users' operational restrains.
Turbulent, stratified flow through a suspended shellfish canopy: implications for mussel farm design

Observations were used to quantify the influences of turbulent flow and mixing through the suspended canopy formed by a shellfish aquaculture farm in the microtidal Danish Limfjorden. Observations included current meter/profiler timeseries data and turbulence microstructure profiling. The influence was 2-way in that the turbulence is partially driven by the canopy and in turn the canopy is affected by the turbulence. The canopy reduced the flow speeds within its interior, which was sufficient to reduce levels of turbulent kinetic energy so that withincanopy rates of turbulent kinetic energy dissipation ε were between 10−8 and 5 × 10−6 m2 s−3. Stratification and turbulence were generally inter-related. It was difficult to link the canopy effect to changes in stratification. This was partly due to a high degree of natural variability and partly because the canopy did not appear to generate that much mixing relative to background variability. Vertical diffusivities enabled estimates of the effect of mixing on nutrient depletion and suggest that in the investigated farm set-up vertical diffusivities are secondary in terms of contribution to this relationship but that they could play a dominant role in farms with a more spacious or compressed set-up of canopies. However, vertical flux estimates imply that there must be transverse fluxes of material. Results suggest several avenues for enhanced sustainable shellfish production. For example, canopy flushing can be enhanced with suitable arrangement of crop within a farmed area (heterogeneity). In addition, stratification persists within the canopy and so exposure to nutrient-deplete water can be minimized through staggered crop heights. However, to benefit from this knowledge, improved understanding of long-term variability in the background environment is required.
Situational Social Support and Relapse: An Exploration of Compulsory Drug Abuse Treatment Effect in China

The present study explores situational social support of drug abusers during compulsory rehabilitation and provides a preliminary estimation of relationship between social support and relapse. Links between social support and relapse are examined in a study of drug abusers accepting coercive detoxification and rehabilitation treatment, and self-reported relapse in the following 6 months (N = 535). External and internal social support with abstinence-specific support inclusive are investigated. With certain demographic variables and risk-related variables controlled, greater special type of external social support (as measured by number of children) predicts a lower risk of relapse, which means better effect of compulsory rehabilitation. Participation into some of the institutional programs and experienced personal conflicts for abstinence show no statistically significant with relapse risk.
Comparison of e-Noses: the case study of honey

Authentication is a major research theme in food analysis. Electronic noses (e-Noses) represent an effective tool for food authentication and - among others - for the determination of food origin. In this work we compare the performance of two e-Noses (metal-oxide-sensor based vs mass-spectrometry based) in the determination of geographic origin of honey. We analyzed 14 honey samples from South Tyrol, an Italian alpine region, which were compared with other 12 commercial samples from diverse European origins. Both e-Noses afforded 85% of correct identifications. Mass spectrometry provided a deep analytical insight, thanks to the possibility to determine mass peaks with good accuracy.
Integrated SAR Receiver/Converter for L, C and X-Bands

The receiver circuit described in this paper is intended for X (9.65 GHz), C (5.41 GHz) or L-band (1.2575 GHz) synthetic aperture radar (SAR) receiver. The circuit includes all the front end excluding the first low noise amplifier (LNA). In the planned application the LNA, together with band pass filters, is a separate circuit. However, the circuit in this paper can also be used as a stand-alone front end in less demanding applications by using its buffer amplifier as the LNA.
Reinventing Organization Development: How a Sensemaking Perspective Can Enrich OD Theories and Interventions

Organization development (OD) has traditionally devoted much attention to organizational change. Recently, however, questions have emerged concerning OD's relevance to solve issues of stagnation in change processes. In this article, it is argued that traditional OD's basic assumptions about people, organization and change may cause a certain myopia with regard to problems that result from patterns of action that people have constructed in their mutual interactions and that may lead to stagnation or deadlock. The goal of this article is to study how a sensemaking approach might help OD practitioners to better understand the phenomena with which they are confronted in organizational change and enrich OD interventions by a more explicit focus on actors' habituated patterns of sensemaking and action. This article describes such a pattern in a police organization, its implications for the change process and lessons for OD assumptions, theory, and interventions.
Inverse optimal control problem: the linear-quadratic case

A common assumption in physiology about human motion is that the realized movements are done in an optimal way. The problem of recovering of the optimality principle leads to the inverse optimal control problem. Formally, in the inverse optimal control problem we should find a cost-function such that under the known dynamical constraint the observed trajectories are minimizing for such cost. In this paper we analyze the inverse problem in the case of finite horizon linear-quadratic problem. In particular, we treat the injectivity question, i.e. whether the cost corresponding to the given data is unique, and we propose a cost reconstruction algorithm. In our approach we define the canonical class on which the inverse problem is either injective or admit a special structure, which can be used in cost reconstruction.
A wind energy policy design: lessons from the Galician case. y

This note is concerned with the success of the wind energy policy undertaken by the Galician regional government from 1995, which turned Galiza into the 6th world wind energy producer. On account of windfarms require a site to operate, such a policy promoted eolian energy by affecting landownership and land uses: windfarms are considered of “public use,” so sites can be condemned via eminent domain unless a rental agreement is reached. The available data report the bargaining process between landowners and eolian firms resulted in few condemnations, and agreement rents lower than the (discounted) condemn compensation. We present a partial equilibrium analysis of the land market that is able to reproduce this outcome, under the assumption of landowners’ lack of information on i) the new policy setting, and ii) the condemn monetary compensations. Our main findings refer to the consequences of the failure of the renewable policy chosen to design an efficient market of land. First, landowners’ shortage of information may account for the achievements of such a policy; and, second, the low rents of the land input went with an inefficient overprovision of competitive land allocation for energy production. Finally, as more information on prices will be available in the future, we predict a higher agreement rents or a dramatic increase in the number of condemnations.
