Selection of autochtone probiotic for Astyanax bimaculatus

This study aimed to isolate native lactic acid bacteria of yellow tail lambari (Astyanax bimaculatus) and evaluate their effect on host microbiota and gut morphology, as well as survival after experimental challenge. The isolated bacterial strains were evaluated for their inhibition against pathogenic bacterial strains in vitro, and the strain with highest inhibitory ability was molecularly identified as Lactobacillus spp. For in vivo testing, eighty fish were distributed in ten tanks equipped with a recirculation system. The experimental units were divided into two treatments: fish fed with Lactobacillus spp. supplement and fish fed an unsupplemented diet (control). After 30 days, guts from three fish from each experimental unit were pooled for microbiological and histological analysis. The other five fish were inoculated with 2.1x10CFU. mL of Aeromonas hydrophila to evaluate survival after 24h. Lambaris fed with the probiotic diet had a lower count of Vibrios spp. , Pseudomonas spp. and Staphylococcus spp. , and a higher count of lactic acid bacteria compared to control treatment, as well as, increased length, width and perimeter of intestinal villi, as well as higher survival rate (16.2%) after experimental challenge compared to the unsupplemented group. The results show that the Lactobacillus spp. used has effect probiotic for yellow tail lambari.
Earnings Management through Tax Reserves and Auditor-Provided Tax Services

This study investigates whether firms continue to use tax reserves to achieve financial reporting objectives in the post-FIN 48 period and the effect of auditor-provided tax services on earnings management through tax reserves. Three types of earnings management incentives are considered in this study: meeting or beating the consensus forecasts, income smoothing, and taking an “earnings bath. ” The analyses yield evidence that only non-large firms manipulate tax reserves to meet/beat earnings forecast in the post-FIN 48 period; however, tax reserves are still utilized by both large and non-large firms to smooth earnings. Moreover, evidence is provided that the auditor who provides more tax services facilitates large firms’ earnings smoothing in the post-FIN 48 period, implying independence impairment. But this behavior does not exist within non-large firms, arguably because the auditor does not compromise independence for less important clients.
Diffusion approximation of a Knudsen gas model: dependence of the diffusion constant upon the boundary condition

In this article we study a model for the dynamics of particles moving freely between two horizontal plates. Our goal is to characterize the diffusive behavior for such systems in the long-time and large (horizontal) scale limits. Using homoge- nization techniques for PDEs, we obtain a diffusion equation as a limit of the original kinetic equation, appropriately scaled. This limiting diffusion can be understood intuitively by observing that in the limit of long times and vanishing vertical distance between the plates, for a given particle, the mean free path between two successive reflections at the plates also vanishes, and therefore the number of reflections grows unboundedly with the length of the time interval. The nature of a particular reflection law then efficiently randomizes the particle motion. More specifically, we study the dependence of the diffusion constant Dα on mixed boundary conditions: the case of specular reflection (based on the "Arnold cat map") with an isotropic component (i.e., with small "accommodation" coefficient α). We find that the diffusion tensor Dα is positive definite for every α ∈ (0, 1). Furthermore, in the limit of vanishing isotropic component (α → 0), we recover the result of Bardos, Golse and Colonna (Physica D, 104 (1997), 32-60).
Multiscale mass transport in z ∼6 galactic discs: fuelling black holes

By using AMR cosmological hydrodynamic N-body zoom-in simulations, with the RAMSES code, we studied the mass transport processes onto galactic nuclei from high redshift up to $z\sim6$. Due to the large dynamical range of the simulations we were able to study the mass accretion process on scales from $\sim50[kpc]$ to $\sim$ few $1[pc]$. We studied the BH growth on to the galactic center in relation with the mass transport processes associated to both the Reynolds stress and the gravitational stress on the disc. Such methodology allowed us to identify the main mass transport process as a function of the scales of the problem. We found that in simulations that include radiative cooling and SNe feedback, the SMBH grows at the Eddington limit for some periods of time presenting $\langle f_{EDD}\rangle\approx 0.5$ throughout its evolution. The $\alpha$ parameter is dominated by the Reynolds term, $\alpha_R$, with $\alpha_R\gg 1$. The gravitational part of the $\alpha$ parameter, $\alpha_G$, has an increasing trend toward the galactic center at higher redshifts, with values $\alpha_G\sim 1$ at radii <$\sim$ few $ 10^1[pc]$ contributing to the BH fueling. In terms of torques, we also found that gravity has an increasing contribution toward the galactic center at earlier epochs with a mixed contribution above $\sim 100 [pc]$. This complementary work between pressure gradients and gravitational potential gradients allows an efficient mass transport on the disc with average mass accretion rates of the order $\sim$ few $1 [M_{\odot}/yr]$. These level of SMBH accretion rates found in our cosmological simulations are needed in all models of SMBH growth that attempt to explain the formation of redshift $6-7$ quasars.
Effect of incorporation of minced broiler skin and whole egg malange on the quality of chicken meat patties

In the present experiment, minced broiler skin (MBS) paste at three different levels (5, 7.5 and 10%) were used to replace both lean meat and fat proportionately in the preparation of chicken patties to study the combined effect of MBS and whole egg malange (WEM) (5%) on the quality of chicken patties. Batter was prepared by hand–mixing the ingredients with minced meat and minced fat and patties were cooked in preheated electrical oven at 180oC for 30 min to an internal temperature of 80oC. Increased level of incorporation of minced broiler skin paste significantly (p<0.05) decreased the emulsion stability of the batter, and percentage yield, moisture, protein, ether extract and ash contents of the cooked patties. Incorporation of broiler skin significantly (p<0.05) increased the shrinkage of the product as indicated by the measurement of diameter and thickness. Scores for the sensory attributes at all levels of minced broiler skin paste incorporation in the patties were fair to good (except juiciness = 5.87) which were comparable to control samples. Refrigerated (4±1°C) storage in LDPE for 15 days resulted in significant (p<0.05) and gradual decrease in all the quality attributes (TBA value, Tyrosine value and microbiological) and sensory scores, but were well within the limits of acceptability. It is concluded that good acceptable quality chicken patties can be prepared by replacing lean meat and fat with minced broiler skin paste at 5.0% level.
Reply to the Comment of A . Pszczólkowski on “ Calpionellid distribution and microfacies across the Jurassic / Cretaceous boundary in western Cuba ( Sierra de los Órganos ) ” by R . López-Martínez et al . ( 2013 )

Discussions about the Jurassic/Cretaceous boundary in Cuba are welcome and expected. We are grateful to A. Pszczółkowski for his interesting comment on our work. Our paper focuses on the calpionellid biostratigraphy and facies distribution to establish the Jurassic/Cretaceous boundary in a “specific” section of the Guasasa Formation named the San Vicente section. Unfortunately, the comment by A. Pszczółkowski included no special mentions of the main objectives of our publication. Comments are mainly stressed out around some minor discrepancies of the results of our contribution with those previously published by the aforementioned author.

Global analysis and indeterminacy in a two-sector growth model with human capital

The purpose of the present paper is to highlight some features of global dynamics of the two-sector growth model with accumulation of human and physical capital analyzed by Brito, P. and Venditti, A. (2010). In particular, we explore two cases where the Brito-Venditti system admits two balanced growth paths each of them corresponding, after a change of variables, to an equilibrium point of a 3-dimensional system. In the former one, the two stationary states have, respectively, a 2-dimensional and a 1-dimensional stable manifold (i.e. they are, in the Brito-Venditti terminology, locally indeterminate of order 2 and determinate, respectively). In the latter case, instead, the stable manifolds of the two equilibria have, respectively, dimension two and three (i.e. they are locally indeterminate of order 2 and 3). In both cases we prove the possible existence of points P such that in any neighborhood of P lying on the plane corresponding to a fixed value of the state variable there exist points Q whose positive trajectories tend to either equilibrium point. Moreover we show examples where the 2-dimensional stable manifold of the order 2 locally indeterminate equilibrium, in the former case, and the basin of the attracting equilibrium, in the latter case, are proven to be both unbounded.
Growth inhibition of human pro-myelocytic leukemia (HL-60) cells by lipid extracts of marine alga Sargassum marginatum (Fucales, Phaeophyta) harvested off Goa (west coast of India) with special reference to fatty acid composition

The present investigation deals with the fatty acid composition of total lipids and different lipid classes of brown seaweed Sargassum marginatum harvested off Goa. An effort was made to screen the growth inhibitiory/cytotoxic activity of lipid extracts on the human pro-melocytic leukemia (HL-60) cells. Phospholipids (PL) were found to be the most effective compared to the other lipid classes in terms of cytotoxic activity. PL exhibited cytotoxic activity at concentrations as low as 20 μg/ml. Phospholipids were found to be higher in poly unsaturated fatty acids (PUFA) among all the lipid classes analysed. This study indicates the possibility of seaweeds as potential sources of anticancer substances. Further works are needed to identify the active compound responsible for this anti-cancerous activity. The role of non-methylene interrupted (NMI) fatty acid specific to Sargassum spp, as anti-cancerous substance, also needs to be elucidated.
An ADPLL Clock Generator with Large Frequency Multiplication Factor for Video Application

In this thesis, an all-digital phase-locked loop with large multiplication factor is presented. This circuit can be applied to the video system as a clock generator. It receives the horizontal synchronous signal from the graphics card and then generates a high frequency pixel clock according to the monitor resolution setting to acquire the video signal data. The stability of this sampling clock affects the display image quality directly. If the pixel clock is not stable, the display image will be glittering or jittering. Therefore, how to design a stable clock generator with large multiplication factor is the point of this thesis. This chip is implemented with standard cell library by synthesis and auto place-and-route tools, and realized using 90nm 1P9M standard CMOS process.
Mapping the methane on Mars

Context. In the past few years several authors have reported detection of a very small amount of methane in the martian atmosphere. Suggested hypotheses for this methane production can be linked either to geological or biological activities, and in both cases our perspective on the planet evolution would require a major revision. Aims. It has been suggested that methane is heterogeneously distributed in the atmosphere, but its temporal and spatial variability is still unknown. Our goal is to describe the distribution of the methane concentration in the martian atmosphere and its temporal evolution, providing insight into its sources and constraining its sinks. Methods. Using the extensive data set of the thermal emission spectrometer onboard Mars Global Surveyor and a statistical clustering technique, here we tracked the gas evolution over three martian years using the ν4 Q-branch methane band at 1306 cm −1 . Results. We identify three localized sources, corresponding to Arabia Terrae, well known for the high content of underground water, and to the two main volcano provinces, Tharsis and Elysium. Our analysis suggests a seasonal cycle of the methane distribution, as well as interannual variations. This discovery potentially constrains the lifetime of the methane molecule in the martian atmosphere to <1 yr, suggesting that there is a process able to remove the methane from the atmosphere much more efficiently than photochemistry (∼350 yr). High concentrations of methane are found in the warmest seasons, when relatively high energy could trigger volatile release, which is related either to geological processes, or outbreaks of biological activity. Our results, obtained with independent data in a new spectral range, are quantitatively consistent with previous estimates of methane concentration, building confidence that there is methane on Mars.
Metabolic surgery for diabetes Mellitus between benefits and risks

The incidence of type 2 diabetes is continuously growing worldwide, with enormous costs for individuals as well as for society. In the last decades, bariatric surgery has emerged as a possible solution for ameliorating metabolic control or even obtaining diabetes remission. Observational trials and metaanalyses demonstrate consistent improvement of type 2 diabetes following various bariatric procedures, but they are generally uncontrolled or they use historic controls as comparators. In recent years, several randomized trials studying the effectiveness of bariatric surgery in type 2 diabetes have been conducted and they all show substantial benefits, with the observation that the majority are shortterm trials. With the increased popularity of diabetes surgery, concerns about its immediate and long-time safety have also grown. The most frequent peri-operative are ulcers or stenosis, obstruction, venous thrombosis, pulmonary embolism and other pulmonary complications, with a mortality of less than 1%. Gastro-intestinal diseases, nutritional deficiencies and psychiatric disorders are the most important longterm problems to be addressed. The uncertainty regarding the long-term effects of bariatric surgery, together with its potential for morbidity and mortality, underline the necessity of large, long-term, randomized clinical trials comparing the best medical therapy with bariatric surgery in patients with type 2 diabetes.
On the local pairing behavior of critical points and roots of random polynomials

We study the pairing between zeros and critical points of the polynomial $p_n(z) = \prod_{j=1}^n(z-X_j)$, whose roots $X_1, \ldots, X_n$ are complex-valued random variables. Under a regularity assumption, we show that if the roots are independent and identically distributed, the Wasserstein distance between the empirical distributions of roots and critical points of $p_n$ is on the order of $1/n$, up to logarithmic corrections. The proof relies on a careful construction of disjoint random Jordan curves in the complex plane, which allow us to naturally pair roots and nearby critical points. In addition, we establish asymptotic expansions to order $1/n^2$ for the locations of the nearest critical points to several fixed roots. This allows us to describe the joint limiting fluctuations of the critical points as $n$ tends to infinity, extending a recent result of Kabluchko and Seidel. Finally, we present a local law that describes the behavior of the critical points when the roots are neither independent nor identically distributed.
Empirical Research of the Impact of Capital Structure on Agency Cost of Chinese Listed Companies

This paper, selecting 775 listed companies from Shanghai and Shenzhen stock markets during three years from 2010 to 2012 as samples, studies the relationship between agency cost and capital structure, using two econometrics methods which are ordinary least squares (OLS) and panel data respectively. Capital structure is calculated by debt-to-asset ratio and long-term liability rate while agency cost is measured by overhead expenses rate and asset turnover rate. The result shows agency cost has a slightly negative correlation to debt-to-asset ratio and there is a positive and insignificant correlation relationship between long-term liability rate and agency cost.
SIERPINSKIZED KOCH-LIKE SIDED MULTIFRACTAL DIPOLE ANTENNA

Koch-like fractal curve and Sierpinski Gasket are syncretized into a novel Sierpinskized Koch-like sided bow-tie (SKLB) multifractal in superior-inferior way. A K4S4 SKLB multifractal dipole fed by a linearly tapered microstrip Balun is designed, simulated, fabricated and measured. The well consistent results from measurement and experiment corroborate validity of design and the multifractal antenna’s superiority and advantages over its monofractal counterparts in impedance, bandwidth, directivity, efficiency, and dimension. Six good matched bands (S11 ≤ −10 dB) with moderate gain (2.12 dBi–9.55 dBi) and high efficiency (87%–97%) are obtained within band 1.5GHz–14.5 GHz, of which f1 = 1.92 GHz, f2 = 3.94GHz, and f3 = 5.09GHz are generally useful. The multibands are all almost omnidirectional or quasi-omnidirectional in H-plane (Phi = 0◦, XOZ) and doughnut-shaped or dented doughnut-shaped in E-plane (Phi = 90◦, Y OZ). So it is an attractive candidate for applications like PCS, IMT2000, UMTS, WLAN, WiFi, WiMAX and other fixed or mobile wireless multiband communication systems.
Effect of Host Plant Part on Larval Body-Color Polymorphism in Helicoverpa Armigera (Lepidoptera: Noctuidae)

ABSTRACT Larvae of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), exhibit a body-color polymorphism that is most distinct in the final instar. Larval coloration was investigated in relation to the effects of host plant diet. Larval coloration was strongly influenced by the plant parts on which larvae fed; larvae that fed on leaves exhibited a higher frequency of green coloration than larvae that fed on flowers and fruit. This pattern also was exhibited in full sibling larvae that had uniform genetic background. Larval performance in terms of survival, developmental period, and pupal weight was better in larvae reared on fruit than in those reared on leaves. Our results suggest that larval coloration was determined primarily by the portion of the plant upon which larvae were reared. Larvae also had a certain degree of plastic response to the diet change, which indicates larvae can adjust body color as they change the part of the host plant where they feed. Although the adaptive consequence of similar body color to plant part is still unknown, diet-induced body-color polymorphism in H. armigera might have some role in helping larvae avoid visual predation.
Interactional perspective on environmental communication in construction projects

Drawing on theories of social interaction, a critical discourse analysis approach is used to examine the resources and constraints on environmental-communication practices in four construction projects in Sweden. The assumption is that talk and action work together to construct, maintain and change organizational structure, social practices, and contractual arrangements. The empirical data were collected through in-depth interviews and field observations where photo documentation was extensively used. The study showed mismatches between information and action, both within the project and between the project and its stakeholders. The mismatches were not caused by a lack of information, but rather by inconsistencies between the communication cultures, the status of the communicator, and the tools used to mediate the information, e.g. the media, discourses and genres used. These discrepancies resulted in a lack of engagement in environmental work in the projects. If environmental and other performances in construction projects are to be improved, more effort needs to be exerted on understanding the dynamics of the social context, human interaction, and the mediating tools used to communicate. This paper suggests an approach that can enhance such an understanding. S'appuyant sur les théories de l'interaction sociale, les auteurs procède à une analyse du discours critique pour examiner les ressources et les contraintes liées aux pratiques en matière d'environnement et de communication dans le cadre de quatre projets de construction en Suède. On suppose que la parole et l'action fonctionnent ensemble pour construire, entretenir et modifier la structure organisationnelle, les pratiques sociales et les dispositions contractuelles. Les données empiriques ont été recueillies au cours d'interviews approfondies et d'observations sur le terrain où la documentation photographique a été largement utilisée. L'étude a montrer des décalages entre l'information et l'action, à la fois dans le cadre de projets et entre projets et parties intéressées. Ces décalages ne sont pas dus à un manque d'information mais plutôt à des incohérences entre cultures de la communication, état du communicateur et les outils utilisés pour médiatiser les informations comme, par exemple, les média, les discours et les genres. Ces différences se sont traduites par un manque d'engagement dans les travaux environnementaux des projets. Si les performances environnementales et d'autres dans le cadre de projets de construction doivent être améliorées, il faut faire davantage d'efforts pour mieux comprendre la dynamique du contexte social, les interactions humaines et les outils de médiatisation utilisés pour communiquer. Cet article suggère une approche qui pourrait améliorer une telle compréhension.
