Numerical Solution for Cuttings' Transport in Inclined and Highly Inclined Drilling Annuli

AbstractIn deviated wellbores, drilled cuttings accumulate under the pipe in the narrow gap of the eccentric annulus; if these cuttings are not removed the drill string will become stuck. Researchers have investigated the effect of eccentricity on an annular velocity profile and have shown it to have a major impact. This phenomenon has led to hypothesize that the annular flow behavior, and in turn the drilled cuttings' flow behavior, could change markedly with such a variation in annular geometry. This paper presents a numerical solution of the drilled cuttings' transport mechanism during inclined transport. Drilling fluid rheology is modeled as Newtonian and power law non Newtonian fluids. The drilled cuttings are introduced into the drilling fluid flow. The mixture is treated as a single phase. The minimum fluid velocity required to lift or roll cutting particles from the narrow gap of the annulus are computed. Model predictions are in a good agreement with the published experimental data.

ClickToPrice: Incorporating Visual Features of Product Images in Price Prediction

E commerce websites provide product images in addition to textual description and other metadata about a product to shoppers. While the use of images in online product positioning is ubiquitous, its effect on shoppers and product prices has not been studied meaningfully in literature. In this paper, we make two primary contributions: (i) we find evidence of a causal link between the features of a product's image and its price, (ii) we conduct a comprehensive evaluation of regression algorithms to predict product price using metadata and image features of the product and find that the Random Forest algorithm provides the best prediction performance on this task. We discuss implications of our findings for e commerce portals and mobile app creators, and present directions for future research to further investigate the predictive power and statistical significance of product images on their prices.
Civil religious contention in Cairo, Illinois: priestly and prophetic ideologies in a "northern" civil rights struggle

We argue that analyses of civil religious ideologies in civil rights contention must include the interplay of both movement and countermovement ideologies and must recognize the ways in which such discourse amplifies conflict as well as serves as a basis for unity. Based on in depth interviews, archival research, and content analysis of civil religious language, this article examines how priestly and prophetic civil religious discourses, and the infusion of Black power ideologies, provided significant and dynamic resources for both movement and countermovement ideologies during periods of civil rights contention in Cairo, Illinois, especially from 1969 to 1972. We compare the ways in which Cairo's civil rights leaders mobilized prophetic versions of civil religion, and concomitantly, how white countermovement organizations used a priestly civil religion. On the prophetic side the themes of "equality," "freedom," "justice," and the "right to revolt" against worldly socio political arrangements were employed. On the priestly side, the theme of "law" and "order" was played up, with a secondary theme that connected religious acquiescence to worldly power with God's will. The former rhetoric saw calls for economic and employment integration within God's will and the nation's destiny. The latter rhetoric contrasted civil rights claims as essentially "un American."

Sex Specific Associations between One Carbon Metabolism Indices and Posttranslational Histone Modifications in Arsenic Exposed Bangladeshi Adults
Venue: Cancer Epidemiology, Biomarkers Prevention

Posttranslational histone modifications (PTHMs) are altered by arsenic, an environmental carcinogen. PTHMs are also influenced by nutritional methyl donors involved in one carbon metabolism (OCM) which may protect against epigenetic dysregulation.  We measured global levels of three PTHMs, which are dysregulated in cancers (H3K36me2, H3K36me3, H3K79me2) in peripheral blood mononuclear cells (PBMC) from 324 participants enrolled in the Folic Acid and Creatine Trial, a randomized trial in arsenic exposed Bangladeshi adults. Sex specific associations between several blood OCM indices (folate, vitamin B12, choline, betaine, homocysteine) and PTHMs were examined at baseline using regression models, adjusted for multiple tests by controlling for the false discovery rate (PFDR) We also evaluated the effects of folic acid supplementation (400 mg/d for 12 weeks) compared with placebo, on PTHMs.  Associations between choline and H3K36me2 and between vitamin B12 and H3K79me2 differed significantly by sex (Pdiff 0.01 and <0.05, respectively) Among men, plasma choline was positively associated with H3K36me2 (PFDR 0.05) and among women, plasma vitamin B12 was positively associated with H3K79me2 (PFDR 0.01) Folic acid supplementation did not alter any of the PTHMs examined (PFDR 0.80)  OCM indices may influence PTHMs in a sex dependent manner, and folic acid supplementation, at this dose and duration, does not alter PTHMs in PBMCs.  This is the first study to examine the influences of OCM indices on PTHMs in a population that may have increased susceptibility to cancer development due to widespread exposure to arsenic contaminated drinking water and a high prevalence of hyperhomocysteinemia.

Dictionary Sparse Recovery via Thresholding Based Algorithms

It is shown that the iterative hard thresholding and hard thresholding pursuit algorithms provide the same theoretical guarantees as \ell _1$$l1 minimization for the recovery from imperfect compressive measurements of signals that have almost sparse analysis expansions in a fixed dictionary. Unlike other signal space algorithms targeting the recovery of signals with sparse synthesis expansions, the ability to compute (near) best approximations by synthesis sparse signals is not necessary. The results are first established for tight frame dictionaries, before being extended to arbitrary dictionaries modulo an adjustment of the measurement process.

Review of high current rating insulated cable solutions

Current rating computations for HV and EHV insulated cables play a crucial role in the planning phase of a new line for both an entirely underground cable link and a mixed or hybrid (cascade connection of overhead and cable line) one. The paper gives a wide overview of the technical solutions which allow very high current ratings in undergrounded insulated cables. These solutions are examined from a theoretical standpoint and practical applications are shown and explained. The paper demonstrates that in underground insulated cables, current rating up to 2500 A can be reached.
A Spectral Estimation Theory for Color Appearance Matching
Venue: Color Imaging: Displaying, Processing, Hardcopy, and Applications

There are several reports describing color vision in subjects who are dichromatic in one eye and trichromatic in the other. Formulae fit to the between eye color appearance matches in such unilateral dichromats have been used to predict color appearance for dichromats [1][2] In this paper, we describe a general principle, spectral estimation theory, that guides how to predict the mapping from two cone class absorptions in a dichromatic eye to three cone class absorptions in a trichromatic eye. The theory predicts matches by first estimating the smoothest, non negative, spectral power distribution that is consistent with the measured cone absorption rates (e.g. of a dichromat) We then use this spectral estimate to calculate the absorption rate for the missing cone type (the standard color observer) In addition to predicting color appearance of dichromats, the theory predicts color appearance matches between color anomalous subjects and the standard color observer. Finally, the theory offers guidance about the possible effects on color appearance of gene therapy treatment for colorblindness.  Many students of color vision have asked how the color experienced by one person may appear to another person. A fascinating series of papers describe one attempt to answer this question by measuring between eye color matches measured in unilateral dichromats: these people are dichromatic in one eye and trichromatic in the other. The between eye color matching experiments were first reported by Judd et al.  and subsequently by Graham et al.  and Alpern et al.  Judd et al.  reported that equal energy light and two narrow band lights at 475 nm and 575 nm look the same when presented to both eyes of a unilateral protanope and a unilateral deuteranope. Alpern et al.  conducted a similar experiment with a unilateral tritanope and reported three eigen colors: equal energy light, narrow band light at 485 and 660.  reported We refer to lights whose color appearance match between the two eyes of a unilateral dichromat as eigen colors. In 1995, Vienot et al.  used the data from these unilateral dichromats to calculate the equivalent color appearance in a standard color observer. Vienot et al.  and later Brettel et al.  noted that eigen colors define an empirical map between two cone coordinates in a dichromatic eye and three cone coordinates in the trichromatic eye. They fit a piecewise linear relationship from the measured to missing cone types using the eigen colors.
Structural Basis of Host Autophagy related Protein 8 (ATG8) Binding by the Irish Potato Famine Pathogen Effector Protein PexRD54*
Venue: The Journal of Biological Chemistry

Filamentous plant pathogens deliver effector proteins to host cells to promote infection. The Phytophthora infestans RXLR type effector PexRD54 binds potato ATG8 via its ATG8 family interacting motif (AIM) and perturbs host selective autophagy. However, the structural basis of this interaction remains unknown. Here, we define the crystal structure of PexRD54, which includes a modular architecture, including five tandem repeat domains, with the AIM sequence presented at the disordered C terminus. To determine the interface between PexRD54 and ATG8, we solved the crystal structure of potato ATG8CL in complex with a peptide comprising the effector's AIM sequence, and we established a model of the full length PexRD54 ATG8CL complex using small angle x ray scattering. Structure informed deletion of the PexRD54 tandem domains reveals retention of ATG8CL binding in vitro and in planta. This study offers new insights into structure/function relationships of oomycete RXLR effectors and how these proteins engage with host cell targets to promote disease.
Potato NPH3/RPT2 Like Protein StNRL1, Targeted by a Phytophthora infestans RXLR Effector, Is a Susceptibility Factor1[OPEN]
Venue: Plant Physiology

An effector from the potato late blight pathogen targets a host protein that negatively regulates immunity. Plant pathogens deliver effectors to manipulate host processes. We know little about how fungal and oomycete effectors target host proteins to promote susceptibility, yet such knowledge is vital to understand crop disease. We show that either transient expression in Nicotiana benthamiana, or stable transgenic expression in potato (Solanum tuberosum) of the Phytophthora infestans RXLR effector Pi02860 enhances leaf colonization by the pathogen. Expression of Pi02860 also attenuates cell death triggered by the P. infestans microbe associated molecular pattern INF1, indicating that the effector suppresses pattern triggered immunity. However, the effector does not attenuate cell death triggered by Cf4/Avr4 coexpression, showing that it does not suppress all cell death activated by cell surface receptors. Pi02860 interacts in yeast two hybrid assays with potato NPH3/RPT2 LIKE1 (NRL1) a predicted CULLIN3 associated ubiquitin E3 ligase. Interaction of Pi02860 in planta was confirmed by coimmunoprecipitation and bimolecular fluorescence complementation assays. Virus induced gene silencing of NRL1 in N. benthamiana resulted in reduced P. infestans colonization and accelerated INF1 mediated cell death, indicating that this host protein acts as a negative regulator of immunity. Moreover, whereas NRL1 virus induced gene silencing had no effect on the ability of the P. infestans effector Avr3a to suppress INF1 mediated cell death, such suppression by Pi02860 was significantly attenuated, indicating that this activity of Pi02860 is mediated by NRL1. Transient overexpression of NRL1 resulted in the suppression of INF1 mediated cell death and enhanced P. infestans leaf colonization, demonstrating that NRL1 acts as a susceptibility factor to promote late blight disease.
Idiosyncratic Jobs, Organizational Transformation, and Career Mobility

Idiosyncratic jobs occur when formal job duties match the abilities or interests of a specific person. New duties can accrue or be negotiated to match an existing employee or a potential hire. Idiosyncratic jobs can help organizations deal with changing contexts, and influence organizational goals and structure. They can affect job holders' careers and organizational job structures. The evolutionary accumulation of idiosyncratic jobs can potentially generate unplanned organizational learning. Promising research frontiers include links to work on job crafting, I Deals, negotiated joining, and ecologies of jobs. Deeper exploration of these domains can advance core theories of job design and organizational transformation and inform normative theory on organizational use of idiosyncratic jobs without falling into cronyism, inefficiency, or injustice.
A Counselling Model for the Promoting Career Development of Erasmus Mobility Participants

The objective of this research paper is the elaboration and expert assessment of a counselling model to develop and support the careers of Erasmus mobility participants. EU funded student mobility programmes significantly contribute to the development of a European identity for young people, however, the link between learning mobility and career has been little explored as yet. This paper is written as a research paper. The field study was conducted at the University of Latvia. This is the first study in Latvia that explores the application and pertinence of career counselling in Erasmus student mobility. The lessons learned through the study of available support for Erasmus mobility participants confirm that students require career counselling to: consciously choose mobility as a career development initiative, raising the return on investment of time and resources, be able to submit more convincing applications to potential placement providers, better recognize and articulate the experience and knowledge acquired during the mobility Original Research Article Jansone and Dislere; BJESBS, 18(1) 1 13, 2016; Article no.BJESBS.28954 2 experience and effectively reflect these to potential traineeship, scholarships or employment providers, or when applying for their next education program. The counselling model created for the development and support of the careers of Erasmus mobility participants elaborated within this paper can serve as an instrument for the evaluation and improvement of career guidance services.
Cumulative Inequalities over the Life Course: Life long Learning and Social Mobility in Britain
Venue: Journal of Social Policy

This paper examines the possibility that life long learning promotes intergenerational class mobility. The following two research questions are asked. Is it the case that further education provides individuals coming from less advantaged origins with a second chance to improve on their educational attainment? Is it the case that the returns to further qualifications, in terms of chances of upward class career mobility, are greater for children from less advantaged backgrounds than for children from more advantaged backgrounds? The analyses that are based on the complete educational and class histories of men and women in a British birth cohort mainly produce negative findings. Children coming from managerial and professional backgrounds seem to benefit most from further education. More specifically, further education appears to be an effective means of career advancement for individuals of managerial and professional origins who start out in their working lives in relatively low level class positions. Via further education they can increase or update their qualifications, and in turn enhance their chances of being counter mobile back to their class of origin. Overall, based on the findings of this paper, we can conclude that qualifications attained through life long learning primarily serve to maintain, rather than to narrow, inequalities attached to social origins in Britain.
Common Agricultural Policy support, technical efficiency and productivity change in French agriculture

This paper investigates how the various changes in the policy supporting agriculture in the European Union, i.e. the Common Agricultural Policy (CAP) and various types of subsidies (investment, production and rural development) affected the technical efficiency and productivity change of farms in France between 1990 and 2006. Three types of farming field crop, dairy and beef cattle are considered. Comparison of efficiency across periods indicates a significant reduction in efficiency in the period following the first CAP reform (1992 MacSharry reform) but an improvement in efficiency change. Econometric results related to the effect of subsidies on efficiency scores (with fixed effect models) and productivity change indices (with ordinary least squares) give ambiguous findings. The effect of a particular type of subsidy was found to be negative or positive depending on the sample's production orientation and on the performance considered. Several methodological recommendations are drawn from the analysis for future research.
The Race between Machine and Man: Implications of Technology for Growth, Factor Shares and Employment

We examine the concerns that new technologies will render labor redundant in a framework in which tasks previously performed by labor can be automated and new versions of existing tasks, in which labor has a comparative advantage, can be created. In a static version where capital is fixed and technology is exogenous, automation reduces employment and the labor share, and may even reduce wages, while the creation of new tasks has the opposite effects. Our full model endogenizes capital accumulation and the direction of research towards automation and the creation of new tasks. If the long run rental rate of capital relative to the wage is sufficiently low, the long run equilibrium involves automation of all tasks. Otherwise, there exists a stable balanced growth path in which the two types of innovations go hand in hand. Stability is a consequence of the fact that automation reduces the cost of producing using labor, and thus discourages further automation and encourages the creation of new tasks. In an extension with heterogeneous skills, we show that inequality increases during transitions driven both by faster automation and introduction of new tasks, and characterize the conditions under which inequality is increasing or stable in the long run.
PHYLOSOPHICAL AND CONSTITUSIONAL PROTECTION TOWARDS RELIGION IN INDONESIA

Legal protection on religion is certainty for a state with Pancasila principle. The first principle the Divinity of the Only God has been spirit of the following points, as living guidance for Indonesian country. The believing of the Divinity of the Only God shows that the Indonesian Republic is religious based country by protecting freedom to have religion for its people. This regulation has implication in governmental circle, that the country makes Religion Ministry as one of ministries that its existence has the same position to other state institutions. The implementation of legal protection toward religion needs legitimating in the field of civil law, showed in issuing President Decree No. 1 of 1965 on the Preventing of Misuse and/or Religion Staining. The existence of this Decree in Old Order has been legitimated newly as a Law by issuing the Law No. 5 of 1969, thus the President Decree has been added to the Criminal Code, Act 156a.
Self Reconfiguring Robotic Framework Using Fuzzy and Ontological Decision Making

Advanced automation requires complex robotic systems that are susceptible to mechanical, software and sensory failures. While bespoke solutions exist to avoid such situations, there is a requirement to develop generic robotic framework that can allow autonomous recovery from anomalous conditions through hardware or software reconfiguration. This paper presents a novel robotic architecture that combines fuzzy reasoning with ontology based deliberative decision making to enable self reconfigurability within a complex robotic system architecture. The fuzzy reasoning module incorporates multiple types of fuzzy inference models that passively monitor the constituent sub systems for any anomalous changes. A response is generated in retrospect of this monitoring process that is sent to an Ontology based rational agent in order to perform system reconfiguration. A reconfiguration routine is generated to maintain optimal performance within such complex architectures. The current research work will apply the proposed framework to the problem of autonomous visual navigation of unmanned ground vehicles. An increase in system performance is observed every time a reconfiguration routine is triggered. Experimental analysis is carried out using real world data, concluding that the proposed system concept gives superior performance against non reconfigurable robotic frameworks.
