Progressing Cavity Pump Application in 40 API Light Oil-The Cooper Basin Field Study
Authors: Clarke Fred 
Published: August 2013

Abstract
The Cooper Basin is one of Australia's largest onshore resource projects. It is geographically located in central Australia in a remote and harsh area commonly known as the "Outback". On behalf of its joint venture partners, Santos operates more than 400 oil wells and 820 gas wells covering an extended operating area of approximately 12,000 square miles. A variety of artificial lift systems are used dependent on reservoir depth and fluid rate. This paper will focus on the application of Progressing Cavity Pumps (PCP) with a review of historical run life data and key lessons learned from 2004 to 2012.
Santos installed its first PCP system in 1990. The trial was considered unsuccessful as a result of a pump failure occurring within a matter of days. No further trials of a PCP system were undertaken until 2004. This second 2 well trial was able to demonstrate the operability of the PCP system by achieving run lives of 180 and 250 days. These results were encouraging enough to move forward with expanded trials in a wider range of reservoirs located in various fields.
The peak of the PCP implementation program in the Cooper Basin reached 145 installations in 2008. Unfortunately many of the applications fell outside of newly understood technical limits. Consequently a number of subsurface failures occurred which resulted in many unplanned workovers. As a result of poor PCP reliability, a change to more dependable forms of artificial lift was undertaken. The total PCP installation base has decreased to 38 systems of which 18 are operating in one particular field achieving pump run lives of 400 to 800 days.
This paper will assist operators to benchmark PCP system performance in similar light oil applications as found in the Cooper Basin. Additionally, the paper will outline a set of technical limits developed from our operating experience and lastly, it will provide a guideline to understand the risks associated with operating PCP systems in a light oil application.

ABSTRACTVerticillium wilt (VW) is one of the important damaging cotton (Gossypium hirsutum L.) diseases worldwide. The use of resistant cultivars has long been considered as the most practical and effective means of controlling VW. The upland cotton cultivar Prema has high VW resistance and is useful for breeding new cultivars resistant to VW. To tag the resistance quantitative trait loci (QTL) in this cultivar, a population of 180 recombinant inbred lines was developed via single seed decent from a cross between the resistant Prema and the susceptible cultivar 86‐1. Verticillium wilt resistance trials were conducted in the artificial disease nursery inoculated with mixed isolates and greenhouse individually with VW defoliating isolates V991 and VD8 over a 2‐yr period. Based on composite interval mapping analysis of the 2010 and 2011 data sets of adjusted disease reaction in the artificial disease nursery, seven resistant QTL were detected. Among them, one major VW‐resistant QTL, which explained 62.83% of the phenotypic variation on the average with logarithm of the odds scores ranging from 23.37 to 26.73, was detected consistently and anchored on chromosome (chr.) D9. Greenhouse experiments revealed the existence of five significant QTL on chr. A9, D3, D11, and D9. Our results showed that qVW‐D9‐1 is a major broad‐spectrum VW resistance QTL. Identification of this QTL will facilitate the marker‐assisted selection of VW resistance in cotton breeding.

ABSTRACTEarly‐maturing maize (Zea mays L.) genotypes yield 15 to 30% less than late‐maturing genotypes. One strategy for improving grain yield in the early‐maturing group involves assessment of grain‐filling traits as secondary traits for selection for high grain yield. In this study, we investigated the possibility of using grain‐filling rate and duration for improving grain yield in early‐maturing tropical maize. Forty‐four hybrids generated using North Carolina design II were evaluated at CIMMYT‐Zimbabwe during the 2011/2012 season under irrigated and nonirrigated environments. Although grain‐filling rate and effective grain‐filling duration were negatively correlated, several hybrids were distinctly above the trend line. The earliest‐maturing hybrid took 127 d to reach physiological maturity and produced grain yields comparable to those of the medium‐maturing genotypes (7 t ha−1). It had a high grain‐filling rate of 2.40 g per plant d−1 (18% higher than those of the low‐yielding hybrids) and a relatively longer effective grain‐filling duration. Grain‐filling rate and effective grain‐filling duration had high coefficients of genetic determination, positive correlations with grain yield, low error terms, and low genotype × environment interactions, making them appropriate selection traits for improved grain yield. The study shows that it is possible to develop high‐yielding early‐ to medium‐maturing maize hybrids based on favorable combining ability values for grain‐filling rate and duration.
Divergence in Drought‐resistance Traits among Parents of Recombinant Peanut Inbred Lines

Published: August 2013

ABSTRACTPeanut (Arachis hypogaea L.) is often grown in climates of intermittent drought on sandy soils. Plants expressing water‐conservative traits would minimize exposure to end‐of‐season, severe drought. Two traits resulting in conservative transpiration rates (TRs) are limitations on TR with soil drying and with increasing vapor pressure deficit (VPD). This study focused on parents of existing recombinant inbred line (RIL) populations as sources of divergent expression of these two traits. If divergence is found, their derived RIL population could be used in identifying genetic markers. Since both water‐conservation traits are laborious to document, a key extension of this study was to explore the possibility of using aquaporin inhibitors as practical tools in marker identification. Tifrunner had a lower soil water threshold for a decline in TR than NC 3033 and N08082olJCT. Tifrunner also had a higher VPD breakpoint than three genotypes, including NC 3033 and N08082olJCT. The difference between Tifrunner and these other two genotypes extended to their response to aquaporin inhibitors. The decrease in TR of Tifrunner when exposed to aquaporin inhibitors was much larger than NC 3033 when treated with silver and N08082olJCT when treated with zinc. This study indicates that an effort to develop drought markers in peanut RIL population should focus on Tifrunner × NC 3033 using the silver inhibitor and/or Tifrunner × N08082olJCT using the zinc inhibitor.

Abstract
Objective—To develop an in vivo CT method to measure inclination angles and motion of the sacroiliac joints in dogs of performance breeds.
Animals—10 German Shepherd Dogs and 12 Greyhounds without signs of lumbosacral region pain or neurologic problems.
Procedures—CT of the ilium and sacrum was performed in flexed, neutral, and extended hind limb positions. Lines were drawn on volume-rendered images acquired in the flexed and extended positions to measure motion of the ilia relative to the sacra. Inclination angles of the synovial and ligamentous components of the sacroiliac joints were measured on transverse-plane CT images acquired at cranial and caudal locations. Coefficients of variance of measurements were calculated to determine intraobserver variability.
Results—Coefficients of variance of measurements ranged from 0.17% to 2.45%. A significantly higher amount of sacroiliac joint rotational motion was detected for German Shepherd Dogs versus Greyhounds. The cranial synovial joint component had a significantly more sagittal orientation in German Shepherd Dogs versus Greyhounds. No significant differences were detected between breeds for x- or y-axis translational motion or caudal synovial or ligamentous joint component inclination angles.
Conclusions and Clinical Relevance—The small amounts of sacroiliac joint motion detected in this study may buffer high-frequency vibrations during movement of dogs. Differences detected between breeds may be associated with the predisposition of German Shepherd Dogs to develop lumbosacral region signs of pain, although the biological importance of this finding was not determined. Future studies are warranted to compare sacroiliac joint variables between German Shepherd Dogs with and without lumbosacral region signs of pain.
Flow-injection spectrophotometric determination of dipyrone in pharmaceutical formulations using a solid-phase reactor with copper(II) phosphate

Published: August 2013

Abstract
In this work, a flow-injection spectrophotometric method for dipyrone determination in pharmaceutical formulations was developed. Dipyrone sample solutions were injected into a carrier stream of deionized water and the reaction was carried out in a solid-phase reactor (12 cm, 2.0 mm i.d.) packed with Cu3(PO4)2(s) entrapped in a matrix of polyester resin. The Cu(II) ions were released from the solid phase reactor by the formation of Cu(II)-(dipyrone)n complex. When the complex is released, it reacts with 0.02% m/v alizarin red S in deionized water to produce a Cu(VABO3)3 complex whose absorbance was monitored at 540 nm. The calibration graph was linear over the range 5.0×10−5–4.0×10−4 mol L−1 with a detection limit of 2.0×10−5 mol L−1 and relative standard deviation for 10 successive determinations of 1.5% (2.0×10−4 mol L−1 dipyrone solution). The calculated sample throughput was 60 h−1. The column was stable for at least 8 h of continuous use (500 injections) at 25°C. Pharmaceutical formulations were analyzed and the results from an official procedure measurement were compared with those from the proposed FIA method in order to validate the latter method.

Note: a new paragraph 'What this study adds:' was added to page 250 on 27 March 2014.Background Social networking sites are web-based services through which individuals can create a public or semi-public profile within a bounded system, connect with a list of other linked users, and view and interact with a list of their connections and with those made by others within the system. To estimate the proportion of university students using social networking sites (SNS) and to determine the association between SNS use and age, gender, nationality, course and year of study, living context, family size, number of close friends, close relationships, stress related to studies and interpersonal relationships. Materials and Methods A cross sectional study was carried out among 300 students from two universities in Ajman, UAE. A self-administered, content-validated and pilot-tested questionnaire was used. The participants answered questions related to their use of social networking sites and details of socio-demographic variables. The data collected were entered into Microsoft Excel and transferred to PASW 18.0 version. Data were analyzed as frequencies, percentages, means and SDs, and Chi-square test used for associations. The odd ratio was calculated for the significant variables to find the degree of association. The SNS usage was categorized as average, moderate or high based on mean and SD on the SNS test score. Results The study population was comprised of 41.6% males and 58.3% females. 89% used social networking sites (SNS) and 11% were non-users. Of the 267 users of SNS, 58.8% were average users, 37.8% moderate users and 3.4% high users. Students in the first and second years of study, small family size, age below 20 years, male gender, being in a non-medical study program, friends in close relationship were found to be associated with higher SNS use. Conclusion Social networking sites were found to be popular among a large number of university students in the UAE, this being more so among males and non-medical students of first two years of study.

Emergency department is one of the most important part of the hospital and also vulnerable to criticism. The reputation of a hospital rests to a large extent on the service of emergency department. The sudden and unexpected nature on the emergency produces panic and psychological disturbances to the relatives, which must be valued and borne in mind during organization and management of services. A descriptive type of cross sectional study was conducted at Emergency Department of National Institute of Cardiovascular Hospital, Dhaka to evaluate the existing facilities, waiting time for the patients for receiving treatment, emergency referral rate and availability of health personnel, overall management and patients suggestion to improve the services of the emergency department. A total of 150 patients were interviewed by a structured questionnaire and a checklist was utilized for equipments and drugs. It was observed that the mean age 49.49 years. About 38.7% patients were attended by doctor within 6-10 minutes. Shifting of the patients form emergency department to another hospital was 12%. 87.3% patients were satisfied with time to complete treatment. In emergency department 69.3% patients were satisfied with reception facility, 89.3% patients were satisfied with given treatment, 92% patients were satisfied with doctors service and 74% patients were satisfied with the service of the support staff. About 90% patients were satisfied with overall management. The findings of cardiac emergency services obtained through check-list were fairly comparable with the opinions expressed by the patients. For further management of emergency department patients gave suggestion for arrangement of waiting room and toilet facility, X-ray and other laboratory facility for emergency patient should be made available for all the duty shift, drugs should be supply adequately and on regular basis. They suggested for augmentation of the equipments, drugs and security and other facilities and recruitment of some trained service providers. According to the patients the Emergency Department is well-studded to manage most of the cardiac emergencies. However, specific problems identified by different stakeholders need to be critically appraised by the authority to improve the services further.DOI: http://doi.dx.org/10.3329/bjdre.v2i2.16245 Bangladesh Journal of Dental Research & Education Vol.2(2) 2012: 52-57
La perception allemande de la notion de souveraineté
Authors: Bieber Roland 
Published: August 2013

Bien que la constitution allemande, le « Grundgesetz », ne connaisse pas le terme Souveränität , cette notion fait partie de la terminologie juridique et politique allemande. Or, on note des différences considérables entre les définitions appliquées par la science politique et par la science juridique ainsi qu’à l’intérieur de chaque discipline... La jurisprudence de la Cour constitutionnelle depuis 1987, notamment dans les arrêts « Maastricht » et « Lisbonne », est marquée par une interprétation de plus en plus explicite des notions d’État, qui reflète les positions d’une partie de la doctrine juridique qui trouvent leurs racines à la fin du xix e siècle. Cependant, la réalité de l’intégration européenne et l’évolution du droit international ainsi que l’ouverture expressément voulue par la constitution allemande, amènent un nombre croissant d’auteurs soit à défendre le concept d’une « souveraineté adaptée », soit à contester l’utilité et la justification de son emploi dans le domaine du droit constitutionnel.
La souveraineté est-elle soluble dans l'Union européenne ?
Authors: Constantinesco Vlad 
Published: August 2013

L’Union européenne – ce processus de plus d’un demi-siècle voulu et continué par un nombre toujours plus élevé d’États membres – a indiscutablement affecté la manière de concevoir la souveraineté des États qui y participent. Cet article étudie les modalités de cette influence et explore la voie que pourrait emprunter une « souveraineté constituante », s’exprimant au niveau de l’Union européenne, à la fois par la décision conjointe les gouvernements des États membres (souverains au sens du droit international) et par ratification des peuples des États membres (souverains au sens du droit constitutionnel).

Published: August 2013

Three each of 3-year-old Angus and Simmental heifers, surgically modified to collect bile, were used to measure the effects of pregnancy and breed on bile flow, biliary copper and zinc excretion and plasma copper and zinc concentrations. Bile copper excretion was significantly higher at 7-mo of pregnancy when samples from both breeds were pooled. From then onwards it declined to its lowest, one week post-partum. During pregnancy, plasma copper concentration increased slightly, reaching its highest level at 7-mo of pregnancy and then decreased slightly until full term. In pooled samples from both breeds, the correlation between increase in bile copper excretion and plasma copper concentration from 0 to 7-mo of pregnancy was high (r = 0.85) and significant (p < 0.05). Plasma zinc concentration decreased to the lowest level around 6-mo of pregnancy but increased thereafter until full term. In cows that were dried off one week after parturition, major shifts in bile and plasma copper and zinc parameters occurred at one week following and these coincided with a marked decline of bile flow and bile copper and zinc excretion. By 3-mo post-partum, biliary copper and zinc excretion and plasma copper and zinc concentrations had reached levels observed prior to pregnancy. When the data from all samples were pooled, the bile flow and bile copper excretion were significantly (p < 0.05) higher in Simmental, and plasma copper and zinc concentration higher in the Angus.
Driving Assessment Tools Used by Driver Rehabilitation Specialists: Survey of Use and Implications for Practice
Authors: Dickerson Anne E. 
Published: August 2013

Abstract
OBJECTIVE. This article describes the use of assessment tools by North American driver rehabilitation specialists (DRSs).
PARTICIPANTS. Participants were 227 self-identified DRSs from the combined databases of two national associations.
MEASURES. Information was solicited through a self-administered survey about the driving evaluation process, assessment tools, and process for making fitness-to-drive recommendations.
RESULTS. More than 80% of the DRSs reported testing visual acuity, range of motion, muscle strength, and fine motor coordination. The most consistently used cognitive–perceptual tests were the Trail Making Tests, Motor-Free Visual Perception Test–Revised, and short cognitive screening tests. A client’s behind-the-wheel performance was the main factor in making a fitness-to-drive recommendation. Few specialists are using computer-based tests or interactive driving simulators.
CONCLUSION. Although use of the Useful Field of View® has increased, there continues to be no consistency in cognitive assessments or guidelines for behind-the-wheel assessment. Implications for practice are discussed.

Published: August 2013

Abstract
This study examined the psychometric properties of item pools relevant to upper-extremity function and activity performance and evaluated simulated 5-, 10-, and 15-item computer adaptive tests (CATs). In a multicenter, cross-sectional study of 200 children and youth with brachial plexus birth palsy (BPBP), parents responded to upper-extremity (n = 52) and activity (n = 34) items using a 5-point response scale. We used confirmatory and exploratory factor analysis, ordinal logistic regression, item maps, and standard errors to evaluate the psychometric properties of the item banks. Validity was evaluated using analysis of variance and Pearson correlation coefficients. Results show that the two item pools have acceptable model fit, scaled well for children and youth with BPBP, and had good validity, content range, and precision. Simulated CATs performed comparably to the full item banks, suggesting that a reduced number of items provide similar information to the entire set of items.

Published: August 2013

Abstract
Despite the inevitable loss of function seen in people with progressive dementias, interventions for reversing or minimizing functional loss are understudied. Research supports task-oriented training, but practical gaps in how to best evaluate clients for this training and how to implement it in clinical settings may be thwarting translation to occupational therapy practice. We structured an intervention model called STOMP (Skill-building through Task-Oriented Motor Practice) using a unique blend of task-oriented training and motor-learning principles. In this article, we describe through a case study the process and outcome of using STOMP to improve functional skills in a woman with moderate dementia with Lewy bodies. Our findings suggest that STOMP has the potential to serve as a structure for the evaluation and treatment of occupational performance deficits in people with dementia and that this model warrants further investigation.

ABSTRACT
This essay discusses the themes and motifs in Ariel Dorfman's play Death and the Maiden and attempts to situate them within a constellation of Southern Cone post-dictatorial traumatic expression, including Jacobo Timerman's testimonial and the 1986 film La historia oficial. The essay argues that not only the specific themes (such as justice, trauma, and revenge in the wake of state-sponsored crimes) but also the historical and demographic context confer upon these works an important place in the growing field of Latin American Jewish literature.
