Fine structure of prefollicular and developing germ cells in the male and female left embryonic chick gonads in vitro with and without androgenic steroids

Pieces of 6and 8-day male and female left embryonic chicken gonads were cultured in vitro for 17 or 21 days in ovo with and without androstenedione (0), dihydrotestosterone (DHT) and estradiol 17 p(E! p). Control cultures of female gonads differentiate into typical ovaries. In the cortex, the prefollicular cells elaborate « lining bodies>> and the germ cells develop Balbiani bodies, intercellular bridges and meiotic prophase figures. The ovarian cortex of treated female gonads is similar to that of controls. Control cultures of male gonads differentiate into typical testes. No cortical tissue is observed. In most cases, treatment with E. p, 0, or DHT induces a partial or complete sexreversal in the male gonads. In the cortex feminized by E, p or 0, the fine structure of prefollicular and germ cel Is is similar to that in females. Although DHT produces an extensive
Herschel -ATLAS: deep HST /WFC3 imaging of strongly lensed submillimetre galaxies

We report on deep near-infrared observations obtained with the Wide Field Camera-3 (WFC3) onboard the Hubble Space Telescope (HST) of the first five confirmed gravitational lensing events discovered by the Herschel Astrophysical Terahertz Large Area Survey (H-ATLAS). We succeed in disentangling the background galaxy from the lens to gain separate photometry of the two components. The HST data allow us to significantly improve on previous constraints of the mass in stars of the lensed galaxy and to perform accurate lens modelling of these systems, as described in the accompanying paper by Dye et al. We fit the spectral energy distributions of the background sources from near-IR to millimetre wavelengths and use the magnification factors estimated by Dye et al. to derive the intrinsic properties of the lensed galaxies. We find these galaxies to have star-formations rates (SFR) ∼ 400–2000 M⊙ yr−1, with ∼(6–25) × 1010 M⊙ of their baryonic mass already turned into stars. At these rates of star formation, all remaining molecular gas will be exhausted in less than ∼100 Myr, reaching a final mass in stars of a few 1011 M⊙. These galaxies are thus proto-ellipticals caught during their major episode of star formation, and observed at the peak epoch (z ∼ 1.5–3) of the cosmic star formation history of the Universe.
KROSS–SAMI: a direct IFS comparison of the Tully–Fisher relation across 8 Gyr sincez ≈ 1

We construct Tully–Fisher relations (TFRs), from large samples of galaxies with spatially resolved H α emission maps from the K-band Multi-Object Spectrograph (KMOS) Redshift One Spectroscopic Survey (KROSS) at z ≈ 1. We compare these to data from the Sydney-Australian-Astronomical-Observatory Multi-object Integral-Field Spectrograph (SAMI) Galaxy Survey at z ≈ 0. We stringently match the data quality of the latter to the former, and apply identical analysis methods and sub-sample selection criteria to both to conduct a direct comparison of the absolute K-band magnitude and stellar mass TFRs at z ≈ 1 and 0. We find that matching the quality of the SAMI data to that of KROSS results in TFRs that differ significantly in slope, zero-point, and (sometimes) scatter in comparison to the corresponding original SAMI relations. These differences are in every case as large as or larger than the differences between the KROSS z ≈ 1 and matched SAMI z ≈ 0 relations. Accounting for these differences, we compare the TFRs at z ≈ 1 and 0. For disc-like, star-forming galaxies we find no significant difference in the TFR zero-points between the two epochs. This suggests the growth of stellar mass and dark matter in these types of galaxies is intimately linked over this ≈8 Gyr period.
Micronucleus level in exfoliated buccal mucosa cells of cancer patients

Micronucleus levels in exfoliated buccal mucosa cells of patients with primary breast, lung, cervix uteri cancer, and patients with Hodgkin's disease were studied (n=59). Significantly increased number of micronuclei in cells of cancer patients was observed compared with healthy persons (n=45). The evaluation of micronuclei number in buccal mucosa cells shows genomic instability in somatic cells of humans.
Space environment of Mercury at the time of the first MESSENGER flyby: Solar wind and interplanetary magnetic field modeling of upstream conditions

[1] The first flyby of Mercury by the Mercury Surface, Space Environment, Geochemistry and Ranging (MESSENGER) spacecraft occurred on 14 January 2008. In order to provide contextual information about the solar wind (SW) properties and the interplanetary magnetic field near the planet, we have used an empirical modeling technique combined with a numerical physics-based SW model. The Wang-Sheeley-Arge (WSA) method uses solar photospheric magnetic field observations (from Earth-based instruments) in order to estimate inner heliospheric conditions out to 21.5 solar radii from the Sun. This information is then used as input to the global numerical magnetohydrodynamic model, ENLIL, which calculates SW velocity, density, temperature, and magnetic field strength and polarity throughout the inner heliosphere. The present paper shows WSA-ENLIL conditions computed for the several week period encompassing the first flyby. This information is used in conjunction with MESSENGER magnetometer data (and the only limited available MESSENGER SW plasma data) to help understand the Mercury flyby results. The in situ spacecraft data, in turn, can also be used iteratively to improve the model accuracy for inner heliospheric “space weather” purposes. Looking to the future, we discuss how with such modeling we can estimate relatively continuously the SW properties near Mercury and at the cruise location of MESSENGER now, for upcoming flybys, and toward the time of spacecraft orbit insertion in 2011.
An evaluation model for the implementation of hospital information system in public hospitals using multi-criteria-decision-making (MCDM) approaches

Background: Hospital Information System (HIS) is implemented to provide high-quality patient care. The aim of this study is to identify significant dimensional factors that influence the hospital decision in adopting the HIS. Methods: This study designs the initial integrated model by taking the three main dimensions in adopting HIS technology. Accordingly, DEMATEL was utilized to test the strength of interdependencies among the dimensions and variables. Then ANP approach is adapted to determining how the factors are weighted and prioritized by professionals and main users working in the Iranian public hospitals, involved with the HIS system. Results : The results indicated that “Perceived Technical Competence” is a key factor in the Human dimension. The respondents also believed that “Relative Advantage," “Compatibility” and “Security Concern” of Technology dimension should be further assessed in relation to other factors. With respect to Organization dimension, “Top Management Support” and “Vendor Support” are considered more important than others. Conclusion: Applying the TOE and HOT-fit models as the pillar of our developed model with significant findings add to the growing literature on the factors associated with the adoption of HIS and also shed some light for managers of public hospitals in Iran to successfully adopt the HIS.
Modification of illite-muscovite crystallite-size distributions by sample preparation for powder XRD analysis

Mean crystallite sizes of illite-muscovite have been obtained by direct measurements usilg TEM on ion-milled (original rock) samples and separates prepared for XRD analysis, and by XRD profile analysis of separates in a prograde sequence of metapelites from southern New Zealand. The mean crystallite sizes determined by the analyses of XRD peak profiles increase with metamorphic grade, consistent with the trend determined by TEM from ion-milled rock samples. However, the sizes obtained by TEM on the ion-milled rock samples are approximately two to fow rimes larger than those by XRD profile analyses. This difference is geater in higher-grade than lower-grade samples. The mean sizes of cryst2llites measured using TEM on the separates that were u5sd 16 6ftein XRD profiles correspond well to those ftom XRD profile analyses. Further TEM and AFM observations of separates show that crystals have been b'roken across and cleaved along (001) planes. These relations indicate that the XRD 6ua 1a,g1g ogtained from samples that differ significantJy from the origilal rock samples; the data indicate that sample preparation for XRD analysis significantly altered the original size-distributions. Crystallite-size distributions are poor approximations to lognormal in original rocks, but are modified to lognormal or nearly lognormal distributions in separates. Interpretation of growth conditions from size distributions of separates is therefore subject to error. Only size distributions of unseparated samples, or separates where the effects of the separation process are known, should be used as indicators of growth conditions.

Reconstructing specular objects with Image Based Rendering using Color Caching

Various Image Based Rendering (IBR) techniques have been proposed to reconstruct scenes from its images. Voxel-based IBR algorithms reconstruct Lambertian scenes well, but fail for specular objects due to limitations of their consistency checks. We show that the conventional consistency techniques fail due to the large variation in reflected color of the surface for different viewing positions. We present a new consistency approach that can predict this variation in color and reconstruct specular objects present in the scene. We also present an evaluation of our technique by comparing it with three other consistency methods.
Autocorrelation in an unobservable global trend: does it help to forecast market returns?

In this paper, a Kalman filter-type model is used to extract a global stochastic trend from discrete non-synchronous data on daily stock market index returns from different markets. The model allows for the autocorrelation in the global stochastic trend, which means that its increments are predictable. It does not necessarily mean the predictability of market returns, since the global trend is unobservable. The performance of the model for the forecast of market returns is explored for three markets: Japan, UK, USA.
Relationship between Mental Health and Interest in Field of Study in Nursing and Midwifery Students

Nursing and midwifery students face high level of stress in their educational experiences which could influence on their mental health status. Furthermore, motivation and interest in field of study are important factors for students’ academic achievement and lack of them conducive to their failure. This study aimed to identifying relationship between mental health and interest in field of study in nursing and midwifery students. In this corrolationalcross sectional study, 209 nursing and midwifery students in Mashhad University of medical sciences were selected by stratified-cluster random sampling. Data were collected by demographic data form, General Health Questionnaire (GHQ-28), and questionnaire for interest in field of study. Data was analyzed by using SPSS software. Results showed according to GHQ score 32.1 % of students had poor mental health. There was a negative significant relation between interest in field of study and mental health status (r= 0.22 P=0.001), the lower interest in field of study brought the higher score of GHQ-28 representing worse mental health status or greater problems. In conclusion; lack of interest in field of study had a negative effect on students’ mental health. So it is recommended to considering students’ interest and providing educational and psychiatric consultation in order to improve educational condition and mental health promotion.

ICLASS 06-151 COMPARISON OF PARTICLE SIZE AND VELOCITY INVESTIGATIONS IN SPRAYS CARRIED OUT BY MEANS OF DIFFERENT MEASUREMENT TECHNIQUES

Measurement techniques for simultaneous droplet sizing and velocimetry are compared in resp ect of their applicability and inherent limitations. A det ailed discussion of the results requires specific correction s f the data to compensate for the inherent effects of the diff rent sampling methods, i.e. flux-sensitive and concentra tion dependent. Among others, these incorporate a correcti on of the diameter-velocity relationship for the flux-dep endent Phase Doppler Interferometry (PDI) and a depth of f ield correction for Shadow Imaging. It is demonstrated, that flux-dependent methods lik e PDI and the concentration imaging techniques Interferom tric Mie Imaging (IMI) and Shadowgraphy yield consistent results at various positions in a dilute spray. While PDI is able to resolve a bi-modal droplet size distributio n, IMI tends to pronounce larger droplets. With respect to the application in the dense sprays for automotive applic ations and high-pressure and elevated temperature conditio s, Shadowgraphy is considered to be least sensitive to beam-steering and multiple light scattering.
The missing complexity in seismically imaged normal faults: what are the implications for geometry and production response?

Abstract The impact of geometric uncertainty on across-fault flow behaviour at the scale of individual intra-reservoir faults is investigated in this study. A high resolution digital elevation model (DEM) of a faulted outcrop is used to construct an outcrop-scale geocellular grid capturing high-resolution fault geometries (5 m scale). Seismic forward modelling of this grid allows generation of a 3D synthetic seismic cube, which reveals the corresponding seismically resolvable fault geometries (12.5 m scale). Construction of a second geocellular model, based upon the seismically resolvable fault geometries, allows comparison with the original outcrop geometries. Running fluid flow simulations across both models enables us to assess quantitatively the impact of outcrop resolution v. seismic resolution fault geometries upon across-fault flow. The results suggest that seismically resolvable fault geometries significantly underestimate the area of across-fault juxtaposition relative to realistic fault geometries. In turn this leads to overestimates in the sealing ability of faults, and inaccurate calculation of fault plane properties such as transmissibility multipliers (TMs).
Analytical description of stochastic field-Line wandering in magnetic turbulence

A nonperturbative nonlinear statistical approach is presented to describe turbulent magnetic systems embedded in a uniform mean magnetic field. A general formula in the form of an ordinary differential equation for magnetic field-line wandering (random walk) is derived. By considering the solution of this equation for different limits several new results are obtained. As an example, it is demonstrated that the stochastic wandering of magnetic field-lines in a two-component turbulence model leads to superdiffusive transport, contrary to an existing diffusive picture. The validity of quasilinear theory for field-line wandering is discussed, with respect to different turbulence geometry models, and previous diffusive results are shown to be deduced in appropriate limits.
JAPANESE MEAT IMPORT DEMAND ESTIMATION WITH THE SOURCE DIFFERENTIATED AIDS MODEL

A source differentiated AIDS model is specified to estimate Japanese meat import demand. Block separability and product aggregation are rejected at conventional levels of significance. The model with the block substitutability restriction explains more than 95% of data variation. The empirical results indicate that the U.S. has the largest potential for beef exports to Japan. Taiwan is in a strong position in the pork market, and Thailand and China are strong in the poultry market. The U.S. competes with Canada and Taiwan in the pork market, but the competition between Taiwan and European countries is the strongest in the market. The U.S. competes with Thailand in the poultry market, where the U.S. is the most vulnerable.
Optical properties of electron-beam evaporated TiO2 films deposited in an ionized oxygen medium

Optical absorption in TiO2 films depends upon starting material and deposition conditions. The influence of the combined effect of substrate temperature and ionized oxygen on the optical properties of TiO2 films deposited by reactive electron beam evaporation of TiO is presented. The ionized oxygen medium reduced the absorption in films considerably. The substrate temperature has only marginal influence on the extinction coefficient of these films. The influence of film thickness on the optical properties of TiO2 films is also studied. The variation in optical properties of TiO2 films has been explained on the basis of enhanced reactivity of oxygen and the decrease of the condensation coefficient of reacting species at elevated substrate temperature.
Future Lending Income and Security Value

I test the Duffie, Gârleanu, and Pedersen (2002) hypothesis that security prices incorporate expected future securities lending income. To determine whether institutional investors anticipate gains from future lending of securities, I examine their trading behavior around loan fee increases. The evidence suggests that institutions buy shares in response to an increase in lending fees and that this could explain the premium associated with high lending fee stocks. Expected future lending income aff ects stock prices, although the e ffect seems to be attenuated by the negative information that arises from short selling.
International Financial Reporting Standards Applied in the Czech Republic

This article provides an extensive analysis of application of International Financial Reporting Standards companies with publicly traded shares in the Czech Republic for 2013. At first the attention is paid to the basic requirements of International Accounting Standards (IAS) and International Financial Reporting Standards (IFRS) and to evaluation of proposed method. Then followed research results, based on an answer to the question of whether the companies are preparing their financial statements in accordance with IAS / IFRS, i.e. whether they serve plenty of mandatory information, and further whether individual companies act similarly. The object of the research consists in further observations regarding the implementation of the new IFRS 9 Financial Instruments, which is designed to replace IAS 39 Financial instruments: recognition and measurement. The level of the information presented was evaluated using a signed test. Using this statistical method we can conclude that companies submit their financial statements in accordance with IAS / IFRS. Using the Friedman test, it was found that the group of companies proceeds with the application of individual IAS / IFRS alike. Only two of seven respondents have already implemented IFRS9. Statistical analysis confirmed that companies reported, in their financial statements, all mandatory information that is relevant to stakeholders. On the other hand, there are also signs pointing to the contrary, but these are not statistically significant. This analysis was provided with detailed knowledge about this phenomenon.
Half-range lattice Boltzmann models for the simulation of Couette flow using the Shakhov collision term

The three-dimensional Couette flow between parallel plates is addressed using mixed lattice Boltzmann models which implement the half-range and the full-range Gauss-Hermite quadratures on the Cartesian axes perpendicular and parallel to the walls, respectively. The ability of our models to simulate rarefied flows are validated through comparison against previously reported results obtained using the linearized Boltzmann-BGK equation for values of the Knudsen number (Kn) up to $100$. We find that recovering the non-linear part of the velocity profile (i.e., its deviation from a linear function) at ${\rm Kn} \gtrsim 1$ requires high quadrature orders. We then employ the Shakhov model for the collision term to obtain macroscopic profiles for Maxwell molecules using the standard $\mu \sim T^\omega$ law, as well as for monatomic Helium and Argon gases, modeled through ab-initio potentials, where the viscosity is recovered using the Sutherland model. We validate our implementation by comparison with DSMC results and find excellent match for all macroscopic quantities for ${\rm Kn} \lesssim 0.1$. At ${\rm Kn} \gtrsim 0.1$, small deviations can be seen in the profiles of the diagonal components of the pressure tensor, the heat flux parallel to the plates, and the velocity profile, as well as in the values of the velocity gradient at the channel center. We attribute these deviations to the limited applicability of the Shakhov collision model for highly out of equilibrium flows.
Flavonoid constituents of the mature fruit of Tetrapleura tetraptera schum. Et Thonn.)

Phytochemical investigation of the ethanolic extract of the mature fruit of Tetrapheura tetraptera led to the isolation of three flavonoid constituents namely 2', 4, 4'-trihydroxychalcone, 2', 3, 4, 4'- tetrahydroxychalcone and 4', 5, 7-trihydroxyflavanone. The structures were established from 1D and 2D NMR experiments. This is the first isolation of flavonoid constituents in the genus Tetrapleura. Keywords : tetrapheura tetraptera, flavonoid, chalcone, flavanone, 1D and 2D NMR. Journal of Science and Technology Vol. 26(1) 2006: 47-53
Wavelet calculus and finite difference operators

This paper shows that the naturally induced discrete differentiation operators induced from a wavelet-Galerkin finite-dimensional approximation to a standard function space approximates differentiation with an error of order 0(h2d+2), where d is the degree of the wavelet system. The degree of a wavelet system is defined as one less than the degree of the lowest-order nonvanishing moment of the fundamental wavelet. We consider in this paper compactly supported wavelets of the type introduced by Daubechies in 1988. The induced differentiation operators are described in terms of connection coefficients which are intrinsically defined functional invariants of the wavelet system (defined as L2 inner products of derivatives of wavelet basis functions with the basis functions themselves). These connection coefficients can be explicitly computed without quadrature and they themselves have key moment-vanishing properties proved in this paper which are dependent upon the degree of the wavelet system. This is the basis for the proof of the principal results concerning the degree of approximation of the differentiation operator by the wavelet-Galerkin discrete differentiation operator.
