Determination of Individual Diffusion Coefficients of C3H8/n-C4H10/CO2/Heavy-Oil Systems at High Pressures and Elevated Temperatures by Dynamic Volume Analysis
Authors: Zheng Sixu , Yang Daoyong 
Published: October 2016

SummaryBy coupling heat and mass transfer for C3H8/n-C4H10/CO2/heavy-oil systems as well as by treating heavy oil as multiple pseudocomponents, a new technique together with its computational scheme has been developed to determine individual diffusion coefficients of alkane solvents and CO2 in heavy oil at high pressures and elevated temperatures by dynamic volume analysis (DVA). Experimentally, well-designed diffusion tests have been conducted for an n-C4H10/heavy-oil system, a CO2/heavy-oil system, an n-C4H10/CO2/heavy-oil system, and a C3H8/n-C4H10/CO2/heavy-oil system by using a visualized pressure/volume/temperature (PVT) setup. The volume change of liquid phase is monitored and recorded during the measurements, whereas the gas-chromatography (GC) method is used to determine the compositions of gas mixtures at the beginning and the end of the diffusion tests. Theoretically, the volume-translated Peng-Robinson (PR) equation of state (EOS) characterizing heavy oil as multiple pseudocomponents has been incorporated to develop a 2D heat-and-mass-transfer model for the aforementioned systems. The alternating-direction-implicit algorithm is applied to solve the 2D difference equations into which a moving gas/liquid interface has been successfully incorporated. The discrepancy between the measured and calculated dynamic-volume change and the discrepancy between the measured and calculated gas compositions at the end of diffusion tests have been minimized to determine the individual diffusion coefficients. Alkane solvents diffuse faster than CO2 in heavy oil, whereas addition of alkane solvent(s) into the CO2 stream not only enhances mass transfer, but also achieves an improved swelling effect of heavy oil. Among the four diffusion tests, the largest dynamic swelling factor at the end of the diffusion test is measured to be 1.118 for the C3H8/n-C4H10/CO2/heavy-oil system.

Authors: Schmid K. S. , Alyafei N.. , Geiger S.. , Blunt M. J. 
Published: October 2016

Summary
We present analytical solutions for capillary-controlled displacement in one dimension by use of fractional-flow theory. We show how to construct solutions with a spreadsheet that can be used for the analysis of experiments as well as matrix-block-scale recovery in field settings. The solutions can be understood as the capillary analog to the classical Buckley-Leverett solution (Buckley and Leverett 1942) for viscous-dominated flow, and are valid for cocurrent and countercurrent spontaneous imbibition (SI), as well as for arbitrary capillary pressure and relative permeability curves. They can be used to study the influence of wettability, predicting saturation profiles and production rates characteristic for water-wet and mixed-wet conditions. We compare our results with in-situ measurements of saturation profiles for SI in a water-wet medium. We show that the characteristic shape of the saturation profile is consistent with the expected form of the relative permeabilities. We discuss how measurements of imbibition profiles, in combination with other measurements, could be used to determine relative permeability and capillary pressure.

Published: October 2016

SummaryAnaphylactic shock due to albumin exposure is rare. The incidence of anaphylactic shock after transfusion is recognised to be higher in ahaptoglobinaemia or IgA‐deficiency patients. We present a rare case of a 67‐year‐old female who developed anaphylactic shock 30 minutes after the infusion of 25% human albumin solution a day following aortic valve replacement surgery. The patient did not have ahaptoglobinemia nor was she IgA deficient. The half‐life of albumin is 19 days, therefore it is important to monitor the patient's clinical course after albumin‐induced adverse events have occurred.

Published: October 2016

SummaryWe describe the use of ultrasound‐guided parasternal Pecs (pectoral nerves) block for pain relief following mastectomy and reconstructive breast surgery. This new ultrasound‐guided parasternal Pecs block provides effective supplementary analgesia when the established block techniques (e.g. Pecs I and serratus anterior block) together with multimodal analgesics fail to ameliorate pain arising from the parasternal area supplied by the anterior cutaneous branches of the intercostal nerves T2‐T6. In this report, the patient undergoing reconstructive breast surgery continued to complain of severe pain even after substantial systemic opioids had been administered postoperatively in the recovery area. When the patient was administered the established Pecs I and serratus anterior blocks the pain was initially reduced markedly, but recurred in the parasternal area. Following administration of an ultrasound‐guided parasternal Pecs block, the pain disappeared and the patient was pain‐free when discharged to the ward.

Influência da diferença esperada na progênie no preço da dose do sêmen de touros da raça Nelore
Authors: Buzzo Álida Mariana dos Reis , Martinez Antonio Campanha 
Published: October 2016

The aim of this study was to evaluate the commercial price of bull’s semen and estimate it’s correlation with genetic characteristics (from the Summary of Program of Genetic Improvement of the Nelore Breed – PMGRN) and with the prizes from Competitions of National Association of Brazil’s Nelore Breeders (ANCB), and verify what influences the final price of bull semen. Data were collected from both ANCB and PMGRN’s Summary 2008. The PROC COR’s SAS V8.0 program was used. Results show that, only the bulls whose calf had won prizes, from the first to the third place, had correlation with the bull’s semen, with 60,6%, 60,2% and 56,5%, respectively. About the heritability characteristics, the only one which had correlation with semen price was birth of weight, with an influence of 17,6% on the bull’s semen price. The most important genetic characteristics when aiming at improving cattle’s genotype in a farm have not been used to determine the price of each dose of commercial semen. Therefore, the present investigation showed that the cattle’s phenotipe has influenced more than inherited characteristics.
Local Bias in Google Search and the Market Response around Earnings Announcements
Authors: Chi Sabrina S. , Shanthikumar Devin M. 
Published: October 2016

ABSTRACT
We examine the impact of distance on internet search, and the effect of the “local bias” in search on the stock market response around earnings announcements. We find significant local bias in search behavior. Motivated by theories explaining local bias, local information advantage, and familiarity bias, we predict and find that firms with higher local bias in search experience higher bid-ask spreads, lower trading volumes, and lower earnings response coefficients at the time of earnings announcements, consistent with non-local investors relying more than locals on public information announcements. Consistent with local information advantage, we find that in the week prior to the announcement, firms with higher local bias have higher bid-ask spreads, higher trading volumes, and returns that are more predictive of the coming earnings surprise. Consistent with familiarity bias, firms with higher local bias in search experience stronger post-earnings announcement drift. We use unique predictions, propensity score matching, and two-stage least squares to identify the effects of local bias separately from the effects of overall visibility. Overall, we show there is significant local bias in search, and that this local bias has a significant impact on the market response around earnings announcements.
Audit Partner Identification: Unintended Consequences on Audit Judgment

Published: October 2016

SUMMARY
We examine the impact of partner identification, a regulation proposed by the PCAOB and contested by the audit profession, on audit partners' judgments. Based on accountability theory (e.g., Lerner and Tetlock 1999) and professionalism literature (e.g., Hall 1968; Adler and Kwon 2013), we conduct an experiment in which we manipulate partner identification at three levels (i.e., no identification, disclosure identification, signature identification) and ask 83 partners to make inventory writedown assessments and other judgments underlying their decision making. We find that, contrary to the PCAOB's stated purpose of enhancing audit quality, and consistent with the professionalism literature, partner identification—in the form of either disclosure or signature—yields more aggressive writedown judgments through its negative impact on partners' self-reported measures of commitment to the profession and, in turn, commitment to the public. This result suggests that regulators should consider possible unintended consequences of accountability-inducing regulations.

ABSTRACT
We report the discovery by the HATSouth network of HATS-18b: a

,

planet in a

day orbit, around a solar analog star (mass

and radius

) with

mag. The high planet mass, combined with its short orbital period, implies strong tidal coupling between the planetary orbit and the star. In fact, given its inferred age, HATS-18 shows evidence of significant tidal spin up, which together with WASP-19 (a very similar system) allows us to constrain the tidal quality factor for Sun-like stars to be in the range of

even after allowing for extremely pessimistic model uncertainties. In addition, the HATS-18 system is among the best systems (and often the best system) for testing a multitude of star–planet interactions, be they gravitational, magnetic, or radiative, as well as planet formation and migration theories.

ABSTRACT
We present H-band near-infrared polarimetric imaging observations of the F5V star HD 157587 obtained with the Gemini Planet Imager (GPI) that reveal the debris disk as a bright ring structure at a separation of ∼80–100 au. The new GPI data complement recent Hubble Space Telescope/STIS observations that show the disk extending out to over 500 au. The GPI image displays a strong asymmetry along the projected minor axis as well as a fainter asymmetry along the projected major axis. We associate the minor and major axis asymmetries with polarized forward scattering and a possible stellocentric offset, respectively. To constrain the disk geometry, we fit two separate disk models to the polarized image, each using a different scattering phase function. Both models favor a disk inclination of ∼70° and a 1.5 ± 0.6 au stellar offset in the plane of the sky along the projected major axis of the disk. We find that the stellar offset in the disk plane, perpendicular to the projected major axis is degenerate with the form of the scattering phase function and remains poorly constrained. The disk is not recovered in total intensity due in part to strong adaptive optics residuals, but we recover three point sources. Considering the system’s proximity to the galactic plane and the point sources’ positions relative to the disk, we consider it likely that they are background objects and unrelated to the disk’s offset from the star.

ABSTRACT
We used the newly commissioned 50 cm Binocular Network telescope at Qinghai Station of Purple Mountain Observatory (Chinese Academy of Sciences) to observe the old open cluster NGC 188 in V and R as part of a search for variable objects. Our time-series data span a total of 36 days. Radial velocity and proper-motion selection resulted in a sample of 532 genuine cluster members. Isochrone fitting was applied to the cleaned cluster sequence, yielding a distance modulus of

and a total foreground reddening of E(V − R) = 0.062 ± 0.002 mag. Light-curve solutions were obtained for eight W Ursae Majoris eclipsing binary systems (W UMas), and their orbital parameters were estimated. Using the latter parameters, we estimate a distance to the W UMas that is independent of the host cluster’s physical properties. Based on combined fits to six of the W UMas (EP Cep, EQ Cep, ES Cep, V369 Cep, and—for the first time—V370 Cep and V782 Cep), we obtain an average distance modulus of

, which is comparable to that resulting from our isochrone fits. These six W UMas exhibit an obvious period–luminosity relation. We derive more accurate physical parameters for the W UMa systems and discuss their initial masses and ages. The former show that these W UMa systems have likely undergone angular momentum evolution within a convective envelope (W-type evolution). The ages of the W UMa systems agree well with the cluster’s age.

ABSTRACT
The Wide Angle Camera of the OSIRIS instrument on board the Rosetta spacecraft is equipped with several narrow-band filters that are centered on the emission lines and bands of various fragment species. These are used to determine the evolution of the production and spatial distribution of the gas in the inner coma of comet 67P with time and heliocentric distance, here between 2.6 and 1.3 au pre-perihelion. Our observations indicate that the emission observed in the OH, O i, CN, NH, and NH2 filters is mostly produced by dissociative electron impact excitation of different parent species. We conclude that CO2 rather than H2O is a significant source of the [O i] 630 nm emission. A strong plume-like feature observed in the CN and O i filters is present throughout our observations. This plume is not present in OH emission and indicates a local enhancement of the CO2/H2O ratio by as much as a factor of 3. We observed a sudden decrease in intensity levels after 2015 March, which we attribute to decreased electron temperatures in the first few kilometers above the surface of the nucleus.
ELLIPTICITIES OF ELLIPTICAL GALAXIES IN DIFFERENT ENVIRONMENTS

ABSTRACT
We studied the ellipticity distributions of elliptical galaxies in different environments. From the ninth data release of the Sloan Digital Sky Survey, we selected galaxies with absolute

-band magnitudes between −21 and −22. We used the volume number densities of galaxies as the criterion for selecting the environments of the galaxies. Our samples were divided into three groups with different volume number densities. The ellipticity distributions of the elliptical galaxies differed considerably in these three groups of different density regions. We deprojected the observed 2D ellipticity distributions into intrinsic 3D shape distributions, and the result showed that the shapes of the elliptical galaxies were relatively spherically symmetric in the high density region (HDR) and that relatively more flat galaxies were present in the low density region (LDR). This suggests that the ellipticals in the HDRs and LDRs have different origins or that different mechanisms might be involved. The elliptical galaxies in the LDR are likely to have evolved from mergers in relatively anisotropic structures, such as filaments and webs, and might contain information on the anisotropic spatial distribution of their parent mergers. By contrast, elliptical galaxies in the HDR might be formed in more isotropic structures, such as galaxy clusters, or they might encounter more torqueing effects compared with galaxies in LDRs, thereby becoming rounder.

ABSTRACT
We present the results of a recent reverberation mapping campaign for UGC 06728, a nearby low-luminosity Seyfert 1 in a late-type galaxy. Nightly monitoring in the spring of 2015 allowed us to determine an Hβ time delay of

days. Combined with the width of the variable Hβ line profile, we determine a black hole mass of

. We also constrain the bulge stellar velocity dispersion from higher-resolution long-slit spectroscopy along the galaxy minor axis and find

km s−1. The measurements presented here are in good agreement with both the

relationship and the

relationship for active galactic nuclei. Combined with a previously published spin measurement, our mass determination for UGC 06728 makes it the lowest-mass black hole that has been fully characterized, and thus an important object to help anchor the low-mass end of black hole evolutionary models.

ABSTRACT
We present measurements of the luminosity-dependent redshift-space three-point correlation functions (3PCFs) for the Sloan Digital Sky Survey Data Release 7 Main galaxy sample. We compare the 3PCF measurements to the predictions from three different halo and subhalo models. One is the halo occupation distribution (HOD) model and the other two are extensions of the subhalo abundance matching model by allowing the central and satellite galaxies to have different occupation distributions in the host halos and subhalos. Parameters in all the models are chosen to best describe the projected and redshift-space two-point correlation functions (2PCFs) of the same set of galaxies. All three model predictions agree well with the 3PCF measurements for the most luminous galaxy sample, while the HOD model better performs in matching the 3PCFs of fainter samples (with luminosity threshold below L*), which is similar in trend to the case of fitting the 2PCFs. The decomposition of the model 3PCFs into contributions from different types of galaxy triplets shows that on small scales the dependence of the 3PCFs on triangle shape is driven by nonlinear redshift-space distortion (and not by the intrinsic halo shape) while on large scales it reflects the filamentary structure. The decomposition also reveals more detailed differences in the three models, which are related to the radial distribution, the mean occupation function, and the velocity distribution of satellite galaxies inside halos. The results suggest that galaxy 3PCFs can further help constrain the above galaxy–halo relation and test theoretical models.
