Published: March 2016

The purposes of this investigation were to determine the effects of different drugs such as GnRH analogue, vitamin AD3E and combination of vitamins and minerals on induction of cyclicity followed by conception in crossbred anoestrus heifers. The effects of body condition score (BCS) and age at anoestrus heifers during treatment on induction of cyclicity and conception were also determined. Sixty crossbred anoestrus heifers having > 2.5 BCS at >24 months age at Potiya Upazilla of Chittagong district were used. The cyclicity of the cows was confirmed by using real time ultrasonography on the basis of presence or absence of corpus luteum. The anoestrus heifers were allotted for 1 to 4 different treatment groups with GnRH analogue, vitamin AD3E and vitamin mineral solution including one no-treatment control group. AI was done in observed oestrus heifers and the conception was determined transrectally by using B-mode real time ultrasonography between 28-35 days post-Al. Heifers showed oestrus at higher (46.67%) proportion in treatment groups than that in no-treatment counterpart (6.67%) (P<0.05). The conception rate was 35.56% in treatment received heifers. The GnRH treated heifers showed the highest (60.00%) proportion of cyclicity and conception rate (46.67%) whereas vitamin mineral solution treated heifers showed the lowest cyclicity (33.33%) and conception rate (26.67%) (P<0.05). Heifers with BCS 3.5 had the highest (57.14%) rate of oestrus induction and (57.14%) rate of conception (P<0.05) whereas heifers with BCS 2.5 had the lowest (41.67%) rate of oestrus induction and (20.83%) rate of conception (P>0.05). Heifer showed highest rate (50.00%) of cyclicity and (38.89%) rate of conception when their age ranges from 36 to 42 months where as heifer showed lowest (37.50%) rate cyclicity and (31.58%) rate conception when their age ranges from 24 to 29 months (P>0.05). In conclusion, treatment of crossbred anoestrus heifers with drugs has positive effect on induction of cyclicity followed by conception. GnRH may be the drug of choice among the drugs tested in this study. The BCS of heifers during treatment influences the treatment outcome with respect to induction of cyclicity followed by conception.
Beckett'sWattand Monastic Tradition
Authors: Marangoni Kristen 
Published: March 2016

The enigmatic setting of Beckett's novel Watt has been compared to places as diverse as an insane asylum, a boarding school, a womb, and a concentration camp. Watt's experience at Knott's house does seem suggestive of all of these, and yet it may more readily conform to the setting of a monastery. The novel is filled with chants, meditations, choral arrangements, hierarchical classifications, and even silence, all highly evocative of a monastic lifestyle. Some of Watt's dialogue (such as his requests for forgiveness or reflections on the nature of mankind) further echoes various Catholic liturgies. Watt finds little solace in these activities, however. He feels that they are largely rote and purposeless as they are focused on Knott, a figure who in many ways defies linguistic description and physical know-ability. Watt's meditations and rituals become, then, empty catechisms without answers, something that is reflected in the extreme difficulty that Watt has communicating.In the face of linguistic and liturgical instability, the Watt notebooks present a counter reading that can be found in the thousand plus doodles that line its pages. The drawings reinforce as well as subvert their textual counterpart, and they function in many ways as the images in medieval illuminated manuscripts. The doodles in Watt often take the form of decorative letters, elaborate marginal drawings, and depictions of a variety of people and animals, and many of its doodles offer uncanny resemblances in form or theme to those in illuminated manuscripts like The Book of Kells. Doodles of saints, monks, crosses, and scribes even give an occasional pictorial nod to the monastic setting in which illuminated manuscripts were usually produced (and remind us of the monastic conditions in which Beckett found himself writing much of Watt).Beckett's doodles not only channel this medium of illuminated manuscripts, they also modernize its application. Instead of neat geometric shapes extending down the page, his geometric doodle sequences are often abstracted, fragmented, and nonlinear. Beckett also occasionally modernized the content of illuminated manuscripts: instead of the traditional sacramental communion table filled with candles, bread and wine, Beckett doodles a science lab table where Bunsen burners replaces candles and wine glasses function as beakers. It is through these modernized images that Watt attempts to draw contemporary relevance from a classic art form and to restore (at least partial) meaning to rote traditions.

ABSTRACT
We report evidence for excess blue light from the Type Ia supernova (Sn Ia) SN 2012cg at 15 and 16 days before maximum B-band brightness. The emission is consistent with predictions for the impact of the supernova on a non-degenerate binary companion. This is the first evidence for emission from a companion to a normal SN Ia. Sixteen days before maximum light, the

color of SN 2012cg is 0.2 mag bluer than for other normal SN Ia. At later times, this supernova has a typical SN Ia light curve, with extinction-corrected

mag and

. Our data set is extensive, with photometry in seven filters from five independent sources. Early spectra also show the effects of blue light, and high-velocity features are observed at early times. Near maximum, the spectra are normal with a silicon velocity v
Si = −10,500 km s−1. Comparing the early data with models by Kasen favors a main-sequence companion of about six solar masses. It is possible that many other SN Ia have main-sequence companions that have eluded detection because the emission from the impact is fleeting and faint.
KINEMATIC DISTANCES OF GALACTIC PLANETARY NEBULAE
Authors: Yang A. Y. , Tian W. W. , Zhu H. , Leahy D. A. , Wu D. 
Published: March 2016

ABSTRACT
We construct H i absorption spectra for 18 planetary nebulae (PNs) and their background sources using data from the International Galactic Plane Survey. We estimate the kinematic distances of these PNs, among which 15 objects’ kinematic distances are obtained for the first time. The distance uncertainties of 13 PNs range from 10% to 50%, which is a significant improvement with uncertainties of a factor of two or three smaller than most previous distance measurements. We confirm that PN G030.2−00.1 is not a PN because of its large distance found here.
EARLY-TYPE HOST GALAXIES OF TYPE Ia SUPERNOVAE. I. EVIDENCE FOR DOWNSIZING

Published: March 2016

ABSTRACT
Type Ia supernova (SN Ia) cosmology provides the most direct evidence for the presence of dark energy. This result is based on the assumption that the lookback time evolution of SN Ia luminosity, after light curve corrections, would be negligible. Recent studies show, however, that the Hubble residual (HR) of SN Ia is correlated with the mass and morphology of host galaxies, implying the possible dependence of SN Ia luminosity on host galaxy properties. In order to investigate this more directly, we have initiated a spectroscopic survey for early-type host galaxies, for which population age and metallicity can be more reliably determined from the absorption lines. In this first paper of the series, we present here the results from high signal-to-noise ratio (≳100 per pixel) spectra for 27 nearby host galaxies in the southern hemisphere. For the first time in host galaxy studies, we find a significant (∼3.9σ) correlation between host galaxy mass (velocity dispersion) and population age, which is consistent with the “downsizing” trend among non-host early-type galaxies. This result is rather insensitive to the choice of population synthesis models. Since we find no correlation with metallicity, our result suggests that stellar population age is mainly responsible for the relation between host mass and HR. If confirmed, this would imply that the luminosity evolution plays a major role in the systematic uncertainties of SN Ia cosmology.
SICK: THE SPECTROSCOPIC INFERENCE CRANK
Authors: Casey Andrew R. 
Published: March 2016

ABSTRACT
There exists an inordinate amount of spectral data in both public and private astronomical archives that remain severely under-utilized. The lack of reliable open-source tools for analyzing large volumes of spectra contributes to this situation, which is poised to worsen as large surveys successively release orders of magnitude more spectra. In this article I introduce sick, the spectroscopic inference crank, a flexible and fast Bayesian tool for inferring astrophysical parameters from spectra. sick is agnostic to the wavelength coverage, resolving power, or general data format, allowing any user to easily construct a generative model for their data, regardless of its source. sick can be used to provide a nearest-neighbor estimate of model parameters, a numerically optimized point estimate, or full Markov Chain Monte Carlo sampling of the posterior probability distributions. This generality empowers any astronomer to capitalize on the plethora of published synthetic and observed spectra, and make precise inferences for a host of astrophysical (and nuisance) quantities. Model intensities can be reliably approximated from existing grids of synthetic or observed spectra using linear multi-dimensional interpolation, or a Cannon-based model. Additional phenomena that transform the data (e.g., redshift, rotational broadening, continuum, spectral resolution) are incorporated as free parameters and can be marginalized away. Outlier pixels (e.g., cosmic rays or poorly modeled regimes) can be treated with a Gaussian mixture model, and a noise model is included to account for systematically underestimated variance. Combining these phenomena into a scalar-justified, quantitative model permits precise inferences with credible uncertainties on noisy data. I describe the common model features, the implementation details, and the default behavior, which is balanced to be suitable for most astronomical applications. Using a forward model on low-resolution, high signal-to-noise ratio spectra of M67 stars reveals atomic diffusion processes on the order of 0.05 dex, previously only measurable with differential analysis techniques in high-resolution spectra. sick is easy to use, well-tested, and freely available online through GitHub under the MIT license.
A STAR-FORMING RING AROUND κ Ori 250 pc FROM THE SUN
Authors: Pillitteri I. , Wolk S. J. , Megeath S. T. 
Published: March 2016

ABSTRACT
X-rays are a powerful probe of activity in early stages of star formation. They allow us to identify young stars even after they have lost the IR signatures of circumstellar disks and provide constraints on their distance. Here, we report on XMM-Newton observations that detect 121 young stellar objects (YSOs) in two fields between L1641 S and κ Ori. These observations extend the Survey of Orion A with XMM and Spitzer (SOXS). The YSOs are contained in a ring of gas and dust apparent at millimeter wavelengths, and in far-IR and near-IR surveys. The X-ray luminosity function of the YSOs detected in the two fields indicates a distance of 250–280 pc, much closer than the Orion A cloud and similar to distance estimates of κ Ori. We propose that the ring is a 5–8 pc diameter shell that has been swept up by κ Ori. This ring contains several groups of stars detected by Spitzer and WISE including one surrounding the Herbig Ae/Be stars V1818 Ori. In this interpretation, the κ Ori ring is one of several shells swept up by massive stars within the Orion Eridanus Superbubble and is unrelated to the southern portion of Orion A/L1641 S.

Published: March 2016

During the last years, more and more online portals were generated and are now available for ecologists to run advanced models with extensive data sets. Some examples are the Biodiversity Virtual e-Laboratory (BioVel) Portal (https://portal.biovel.eu) for ecological niche modelling and the Mobyle SNAP Workbench (https://snap.hpc.ncsu.edu) for evolutionary and population genetics analysis. Such portals have the main goal to facilitate the run of advanced models, through access to large-capacity computers or servers. In this study, we present the Analysis Portal (www.analysisportal.se), which is a part of the Swedish LifeWatch e-infrastructure for biodiversity research that combines a variety of Swedish web services to perform different kinds of dataprocessing.
For the first time, the Swedish Analysis Portal for integrated analysis of species occurrence data is described in detail. It was launched in 2013 and today, over 60 Million Swedish species observation records can be assessed, visualized and analyzed via the portal. Datasets can be assembled using sophisticated filtering tools, and combined with environmental and climatic data from a wide range of providers. Different validation tools, for example the official Swedish taxon concept database Dyntaxa, ensure high data quality. Results can be downloaded in different formats as maps, tables, diagrams and reports.
L’intervention sociologique : un mode de production de connaissances entre science et société
Authors: Audoux Christine 
Published: March 2016

Résumé La recherche intervention, théorisée par Marc Uhalde, est déployée dans les organisations par le sociologue pour produire des connaissances situées à des fins de transformation des rapports sociaux. Nous interrogeons la capacité de ce mode de recherche à produire des connaissances valides au regard de la discipline sociologique en le resituant dans la pluralité des rapports de production entre science et société. La recherche intervention, revisitée à l'aune des notions de « science en société » et de « démocratie technique », révèle les modalités hybrides qui la composent et en font une combinaison singulière entre production de connaissances à distance des acteurs de l'organisation et coproduction de sens et de capacités avec ces acteurs.
L’informatique, discipline scolaire
Authors: Archambault Jean-Pierre 
Published: March 2016

L’informatique est partout, dans la vie quotidienne de chacun, l’entreprise et les administrations, la société. L’enjeu afférent est de donner à tous une culture générale informatique correspondant aux exigences de l’époque, de former l’homme, le travailleur et le citoyen, à savoir les missions traditionnelles de l’École.Selon quelles modalités ? L’approche pédagogique selon laquelle les apprentissages doivent se faire exclusivement à travers les usages de l’outil informatique dans les différentes matières scolaires existantes, traduite dans le B2i, s’est révélée être un échec, un échec prévisible d’ailleurs.Les sciences physiques sont devenues matière scolaire parce qu’elles sous-tendaient les réalisations de la société industrielle. Or le monde devient numérique... Un enseignement de spécialité optionnel « Informatique et Sciences du numérique » a été créé en Terminale S. Il entrera en vigueur à la rentrée 2012. Ce premier pas positif en appelle d’autres. Il existe une complémentarité entre l’informatique outil pour enseigner et l’informatique objet d’enseignement qui se renforcent mutuellement.Le long et tortueux cheminement de l’informatique discipline scolaire ne doit pas surprendre : le nouveau émerge toujours dans la douleur.
Practical Considerations for Standard Flaw Acceptance Criteria on Subsea Pipeline Girth Welds
Authors: Reeves K. D. , Tran T. 
Published: March 2016

Abstract
Modern subsea pipelines are now routinely exposed to high strains. When above yield they receive appropriate attention since Engineering Critical Assessment (ECA) derived flaw acceptance criteria would normally be considered mandatory. For stress based designs, (applied axial strain up to 0. 4%), standard flaw acceptance criteria, that originated with empirically based workmanship levels, will be applied unless an optional ECA has been performed. Some of the best current guidance for ECA on pipeline girth welds can be found in DNV-OS-F01 [1]. DNV also provide guidance for workmanship level flaw sizes, (height and length) to be used with Automated Ultrasonic Testing (AUT).
In this paper the tolerability of the DNV-guided workmanship level flaw sizes has been assessed using ECA. The methodology used in this study is in line with the guidance as per DNV-OS-F101 (2013) [1]. When applying this it can be seen that DNV-guided workmanship flaw sizes may not be considered appropriate when the applied strain approaches yield level. This finding implies that the extra testing and analysis required for ECA may result in more stringent acceptance criteria, which does not make sense and creates confusion in the industry. It may be that the recommended ECA methods are overly conservative or the recommended workmanship flaw sizes are not actually safe, or both.
New initiatives have recently been launched, (e.g. TWI) to standardize ECA for pipeline girth welds and based on the findings here it is recommended that these studies also check workmanship flaw acceptance and if necessary restrict further the domain in which they can be applied, e.g. adjust the maximum applied stress to well below yield. It would be useful if a standard ECA approach could consistently allow less stringent criteria over the domain that ‘workmanship’ acceptance criteria can be applied when overmatching weld strength and good toughness data are ensured by testing and enhanced welding control.
An Evaluation of Essential Parameters for Enhancing Drilling Efficiency for ERD Wells Profile
Authors: Salam Mohamed Abdel , Goswami Shreyasi , Hamed Mohamed 
Published: March 2016

Abstract
Drilling efficiency depends on several dynamic factors and challenges. Horizontal drilling well design is critical to maximizing production and reservoir contact particularly cases in which several fluid engineering aspects affect drilling. Challenges increase when transitioning from horizontal to extended-reach drilling (ERD); however, minimizing metal-metal or metal-formation friction is vital. This paper presents a detailed study of laboratory testing of a range of lubricants and software simulation models of a true drilling environment to minimize friction.
For nearly a decade, efforts to reduce friction have focused on engineering the lubricant only without taking into consideration additional factors that could help diminish friction. The challenges of drilling reservoirs are numerous; however, the availability of intelligent software allows for replication of the actual conditions precisely enough to design and drill wells with minimum friction, while taking into account the numerous aspects affecting success. A detailed laboratory study that included software simulation was conducted to create a true ERD environment model with the goal of creating a plan to reduce friction; thus, improve production.
During one of the ERD intelligent projects, the service company team successfully simulated a scenario showing how the drilling fluid behaves under downhole conditions. Taken into consideration were temperature and pressure, the effect of tripping pressures on the equivalent static density (ESD), the effect of drilling parameters on equivalent circulating density (ECD), and the effect of lubricants on performance of different types of fluid design. A comprehensive study of all the parameters was completed, and their effect on drilling performance was determined. Both laboratory-prepared fluids and field fluids were further studied for high-pressure/high-temperature (HP/HT) rheology, lubricity, tripping pressure calculations, and ECD predictions to identify any gaps. Both data sets were consistent, allowing for excellent predictions for the fluid performance when well geometry is known.
A wide range of lubricants, both solid and liquid, and their effects were studied as well as the effect of using ester-based oil to formulate nonaqueous synthetic fluid. The study was extended to include both clay-based and clay-free invert emulsion fluids (IEF), including variable concentrations of ester-based fluid at different oil/water ratios and with different types of lubricants to present a comprehensive overview of all aspects of lubricity.
