    Secondary recovery projects initiated annually by Atlantic Richfield Co. in the U.S. show a general trend somewhat characteristic of all U.S. producers. Why did the number of project starts decline. Simply because there was a lack of prospects for Atlantic Richfield to apply waterflooding economically. This raises the question of what is the next step to maintain U.S. oil producing rates. One answer is to recover a third crop of oil from those fields which have already undergone secondary recovery. It is becoming evident that tertiary recovery must be undertaken while the existing wells and surface equipment are still intact and usable. Very few prospects are expected to be so profitable that economics will permit redrilling of wells and replacement of surface equipment, but tertiary recovery will be applicable to many of the existing oil fields. Engineers and production personnel at all organizational levels must make an effort to recognize those fields under their supervision which are candidates for tertiary recovery applications.

  2. Tertiary oil recovery: potential application and constraints

    Geffen, C. A.


    The technology of tertiary oil recovery methods is described and potential economic and environmental constraints to future commercial application are identified. Oil recoverable by tertiary techniques represents a domestic resource of between 11- and 42-billion barrels. Estimates of additional oil supplies from tertiary methods by the year 2000 range from 1 to 8 million barrels per day, depending on the price of oil and the rate of technological development. The principal constraints to large-scale application of tertiary methods at the present time include environmental, economic and technological concerns. Regulatory action associated with the Clean Air Act Amendments of 1977 currently delay the expansion of thermal recovery operations in California and may discourage future projects. The high production costs of tertiary projects also hamper process implementation. Further testing and research is necessary to develop the technology of tertiary recovery methods and prove these techniques successful on a field-wide scale. To enable tertiary oil recovery to play a significant role in augmenting domestic energy supplies, further research and development is necessary. More accurate methods of determining reservoir structure and residual oil saturations are required, as well as means for assuring the technical feasibility and success of a tertiary method in different reservoir types. Technical process limitations must also be resolved. The severity of potential environmental impacts and constraints identified in this report should be determined. These concerns include the air pollutant emissions from steam generation in thermal processes; acceptable methods of brine disposal; damage due to runoff or accidental discharge of oil-rich chemicals into surface waters; the impacts of fluid injection on deep aquifers and the prevailing geological structure; and an adequate supply of high quality fresh water.

  3. Potential impact of tertiary oil recovery

    Tertiary oil recovery is America's energy ace-in-the-hole and the technology developed here over the past decade could well offer the rest of the world a big incremental boost in its future oil supplies. While U.S. producers are carefully engineering fields that have finished secondary phases of oil production, international operators are commencing pressure maintenance projects by water and gas injection, the first stage of improved oil recovery. Oil recovery authorities who have dealt with the problem for decades estimate that from 25 to 50 billion bbl could be recovered by relatively new sophisticated processes initially developed in the research laboratory and tested in the field. There are 4 basic processes that indicate promise of commercial applications. These are (1) hydrocarbon miscible which includes high-pressure gas drive, rich gas or LPG driven by gas; (2) carbon dioxide miscible with CO/sub 2/ driven by gas or water; (3) chemical flooding, such as surfactant, micellar slugs driven by an aqueous polymer solution; and (4) thermal processes.

    Objective: To examine the relationship between recovery experience, occupational stress, and physiological health of nurses in a municipal grade A tertiary hospital. Methods: A total of 296 in-service nurses from 7 municipal grade A tertiary hospitals were selected from October 2015 to February 2016. Individual characteristics of the subjects were collected using a self-made questionnaire. The recovery experience, occupational stress, and physiological health of the subjects were assessed based on the physiological health dimensions in the Chinese version of Recovery Experience Questionnaire (REQ-C) , Job Content Questionnaire (JCQ) , and Quality of Work Life (QWL7-32) . Results: The mean recovery experience score of nurses from the municipal grade A tertiary hospital was 45.04±7.72, and 51.35% of the nurses had satisfactory recovery experience. Occupational stress was identified in 81.76% of the nurses. Based on the four categories of occupational stress, 65 nurses were identified with high-strain jobs (21.95%) , 56 with relaxed (low-strain) jobs (18.92%) , 49 with passive jobs (16.55%) , and 126 with active jobs (42.57%) . In addition, the mean physiological health score of the nurses was 21.20±4.24. Physiological health was negatively correlated with occupational stress (r=-0.173, Pstress (r=-0.116, Pstress, where subjects with high-demand active jobs had the poorest recovery experience (F=2.610, Phealth (F=8.166, Pstress of nurses, where increased job demand can lead to stronger stress response, reduced recovery experience, and poorer physiological health.

    Full Text Available Orientation: Although work characteristics and recovery strategies are associated with work- family interference, the influence on specific types of work-nonwork interference (W-NWI has not been investigated. Research purpose: The aim of this study was to investigate the impact of work characteristics and recovery strategies on four types of W-NWI.Motivation for the study: It is clear from the literature that job characteristics and W-NWI have adverse effects on employees’ health and well-being. It is therefore important to identify work characteristics and recovery strategies associated with W-NWI.Research design, approach and method: A cross-sectional survey design was used in this study. The target population was married employees with children working at a Tertiary Education Institution (TEI in the North West Province (N = 366.Main findings: Work pressure and emotional demands significantly predicted all the work-nonwork role interference dimensions. A lack of autonomy predicted work-parent interference and work-religion and/or spirituality interference, whilst a lack of development possibilities predicted work-religion and/or spirituality interference. Relaxation and mastery recovery experiences significantly predicted lower work-parent interference. A lack of psychological detachment and relaxation were significantly associated with lower work- spouse interference. Relaxation and control significantly predicted lower work-domestic interference, whilst psychological detachment significantly predicted lower work-religion and/or spirituality interference.Practical/managerial implications: The results give managers insight into the specific work characteristics and recovery experiences that play a role in W-NWI, upon which interventions can be based to address these issues.Contribution/value-add: This study provides information on the relationship between work characteristics, recovery experiences and the effect on different types of W-NWI.

  6. Photoautotrophic Microalgae Screening for Tertiary Treatment of Livestock Wastewater and Bioresource Recovery

    Full Text Available Photoautotrophic microalgae offer high promise for a tertiary treatment of livestock wastewater owing to their rapid growth and nutrient uptake. To screen better microalga for the tertiary treatment, batch photobioreactor tests were conducted using Chlorella emersonii, Chlorella sorokiniana, and Botryococcus braunii. This study evaluated their specific growth rates, CO2 utilization rates, and nutrient removal rates to provide appropriate selection guidelines. Based on statistical comparisons, results indicate that selecting the right microalgae was the key to success in the tertiary treatment since each microalga responded differently, even under the same light, temperature, and nutrient conditions. Among the tested species, Chlorella emersonii was found to present the fastest photoautotrophic growth, total inorganic carbon (TIC utilization, and nutrient removal for livestock wastewater treatment. Regression results identified that its specific growth and total nitrogen removal rates were as high as 0.51 day−1 and 0.18 day−1, respectively. Estimated TIC utilization over the supplied TIC was much higher (~34% than those of others (11%–18%. This systemic evaluation of rate-limiting factors provides a quantitative understanding of the kinetic-based selection strategy of microalgae to polish livestock wastewater with better effluent quality.

  7. Introduction of enhanced recovery for elective caesarean section enabling next day discharge: a tertiary centre experience. (United States)

    Wrench, I J; Allison, A; Galimberti, A; Radley, S; Wilson, M J


    The widespread adoption of enhanced recovery programmes in various surgical specialties has resulted in patient benefits including reduced morbidity, reduced length of stay and an earlier return to normal activities. This evidence, along with the increased financial pressures in the UK National Health Service, has led many units to consider introducing such a programme for obstetric surgery. We report our experience in setting up an enhanced recovery programme for women undergoing elective caesarean section and a prospective analysis of factors that influence length of stay. An enhanced recovery pathway was designed by a multidisciplinary team and introduced in March 2012. Factors influencing length of stay were determined using a log normal model. The proportion of women discharged on Day 1 increased from 1.6% in the first quarter of 2012 to 25.2% in the first quarter of 2014. The 30-day readmission rate was 4.4% for those discharged on Day 1 and 5.6% for Day 2. Earlier gestation, multiple birth, intention to breast feed, longer surgery and more time in the post-anaesthesia recovery unit were all independently associated with a longer postoperative stay. Women presenting for obstetric surgery with the indication "one previous caesarean section" were more likely to leave hospital earlier compared to most other indications. An enhanced recovery programme was successfully introduced into our unit. Many of the interventions were straightforward and could be adopted easily elsewhere. Copyright © 2015 Elsevier Ltd.

  8. Integrating microalgae tertiary treatment into activated sludge systems for energy and nutrients recovery from wastewater. (United States)

    Arias, Dulce Maria; Solé-Bundó, Maria; Garfí, Marianna; Ferrer, Ivet; García, Joan; Uggetti, Enrica


    In this study, microalgae digestate and secondary effluent were used to grow microalgae in a tertiary wastewater treatment, and then, the biomass was co-digested for biogas generation. A 30L closed-photobioreactor was used for microalgae cultivation. The biomass, mainly composed by Scenedesmus sp., reached and maintained a concentration of 1.1gTSS/L during 30days. A complete removal of N-NH4+ and P-PO43- and high nitrates and organic matter removals were achieved (58% N-NO3- and 70% COD) with 8d of HRT. The potential biogas production of the cultivated microalgae was determined in batch tests. To improve their biodegradability, a novel method combining their co-digestion with activated sludge after a simultaneous autohydrolysis co-pretreatment was evaluated. After the co-pretreatment, the methane yield increased by 130%. Thus, integrating microalgae tertiary treatment into activated sludge systems is a promising and feasible solution to recover energy and nutrients from waste, improving wastewater treatment plants sustainability.

    The report investigates the technical feasibility of using the HTR modular reactor for steam supply to tertiary oil recovery, and for hydrogen recovery from the resulting petroleum gas. The report focusses on the design of the two main components, HTR modular reactor with a steam generator, and HTR modular reactor with a steam reformer, and on explaining the alternative system concepts feasible by varying the mode of combination of the two main components. Also, the design concept of a system for heat transport using nuclear long-distance energy (ADAM and EVE) is explained. The technical aspects of the required water treatment system and of the gas production unit for hydrogen recovery are discussed. (orig.).

  10. Psychological recovery and its correlates in adults seeking outpatient psychiatric services: An exploratory study from an Indian tertiary care setting. (United States)

    Gandotra, Aditi; Mehrotra, Seema; Bharath, Srikala


    The study was designed to explore psychological recovery and its correlates in adults receiving outpatient mental health services for psychiatric disorders. It specifically aimed at examining the association of psychological recovery with symptomatic and functional recovery and with selected illness and treatment variables. The relationship of psychological recovery with perceived social support was also the focus of inquiry. The study utilized a cross sectional survey design with a sample of 90 participants diagnosed with severe and common mental illness who had been seeking outpatient psychiatric follow up services. The data was collected with the help of both clinician rated and self-rated measures. The study findings suggested that symptomatic, functional and psychological recovery are significantly correlated but not completely overlapping constructs. Nearly 40% of the sampled participants were at the lower stages of psychological recovery, despite the fact that a majority of them were rated by clinicians as having mild or lower severity of symptoms. With respect to socio-demographic variables, a significant association was found between higher levels of education and psychological recovery. The participants with common mental illness were significantly lower on self-reported improvement and higher on moratorium subscale of psychological recovery (as compared to those with severe mental illness), indicating their struggle in dealing with a sense of loss and despair. Findings also suggested that higher levels of overall perceived social support is likely to facilitate psychological recovery. Copyright © 2017 Elsevier B.V. All rights reserved.

    The goal of treatment in mental illness has evolved from a symptom-based approach to a personal recovery-based approach. The aim of this study was to evaluate the predictors of personal recovery among patients with bipolar disorder. A total of 185 patients with bipolar disorder, currently in remission, were evaluated on Recovery Assessment Scale (RAS), Internalized Stigma of Mental Illness Scale (ISMIS), Brief Religious coping scale (RCOPE), Duke University Religiosity Index (DUREL), Religiousness Measures Scale, Hamilton depression rating scale (HDRS), Young Mania rating scale (YMRS) and Global Assessment of Functioning (GAF) scale. The mean age of the sample was 40.5 (standard deviation (SD), 11.26) years. Majority of the participants were male, married, working, Hindu by religion and belonged to extended/joint families of urban background. In the regression analysis, RAS scores were predicted significantly by discrimination experience, stereotype endorsement and alienation domains of ISMIS, level of functioning as assessed by GAF, residual depressive symptoms as assessed by HDRS and occupational status. The level of variance explained for total RAS score and various RAS domains ranged from 36.2% to 46.9%. This study suggests that personal recovery among patients with bipolar disorder is affected by stigma, level of functioning, residual depressive symptoms and employment status of patients with bipolar disorder. © The Author(s) 2016.

    The Paradox Basin of Utah, Colorado, and Arizona contains nearly 100 small oil fields producing from shallow-shelf carbonate buildups or mounds within the Desert Creek zone of the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to four wells with primary production ranging from 700,000 to 2,000,000 barrels (111,300-318,000 m{sup 3}) of oil per field at a 15 to 20 percent recovery rate. Five fields in southeastern Utah were evaluated for waterflood or carbon-dioxide (CO{sub 2})-miscible flood projects based upon geological characterization and reservoir modeling. Geological characterization on a local scale focused on reservoir heterogeneity, quality, and lateral continuity as well as possible compartmentalization within each of the five project fields. The Desert Creek zone includes three generalized facies belts: (1) open-marine, (2) shallow-shelf and shelf-margin, and (3) intra-shelf, salinity-restricted facies. These deposits have modern analogs near the coasts of the Bahamas, Florida, and Australia, respectively, and outcrop analogs along the San Juan River of southeastern Utah. The analogs display reservoir heterogeneity, flow barriers and baffles, and lithofacies geometry observed in the fields; thus, these properties were incorporated in the reservoir simulation models. Productive carbonate buildups consist of three types: (1) phylloid algal, (2) coralline algal, and (3) bryozoan. Phylloid-algal buildups have a mound-core interval and a supra-mound interval. Hydrocarbons are stratigraphically trapped in porous and permeable lithotypes within the mound-core intervals of the lower part of the buildups and the more heterogeneous supramound intervals. To adequately represent the observed spatial heterogeneities in reservoir properties, the phylloid-algal bafflestones of the mound-core interval and the dolomites of the overlying supra-mound interval were subdivided into ten architecturally distinct lithotypes, each of which

  17. Absolute Lymphocyte Count Recovery Independently Predicts Outcome in Childhood Acute Lymphoblastic Leukemia: Experience From a Tertiary Care Cancer Center of a Developing Country. (United States)

    Gupta, Anshul; Kapoor, Gauri; Jain, Sandeep; Bajpai, Ram


    Accurate risk stratification is essential for successful treatment outcome in childhood acute lymphoblastic leukemia. Early recovery of absolute lymphocyte count (ALC) during induction therapy is emerging as a reliable favorable prognostic indicator that may hold its relevance in resource-constraint settings. This is a retrospective chart review of medical records of 212 patients of acute lymphoblastic leukemia, aged less than 18 years, treated between January 1996 and December 2009. Time to lymphocyte recovery was analyzed with respect to various prognostic factors and survival and Martingale residuals were used to define ALC cut-offs. High-risk disease characteristics including older age (10 y and older), National Cancer Institute high risk, and central nervous system disease at diagnosis were associated with delayed lymphocyte recovery. The 5-year event-free, relapse-free, and overall survival of patients with day 15 ALC of ≥ 500 cells/µL and day 29 ALC of ≥ 1000 cells/µL was 81.7% ± 4%, 86.4% ± 2.8%, 91.0% ± 3%, respectively, compared with those with delayed recovery (16.6% ± 5.6%, 19.3% ± 6.4%, 32.8% ± 7.2%, P < 0.001). In multivariate analysis both these ALC cut-offs retained their significance as prognostic variables of survival. Our analysis revealed ALC to be an important independent predictor of treatment outcome and may provide key prognostic information in settings where minimal residual disease-based risk stratification is not feasible.

    The Paradox basin of Utah, Colorado, and Arizona contains nearly 100 small oil fields producing from carbonate buildups or mounds within the Pennsylvanian (Desmoinesian) Paradox Formation. These fields typically have one to four wells with primary production ranging from 700,000 to 2,000,000 barrels (111,300-318,000 m{sup 3}) of oil per field at a 15 to 20 percent recovery rate. At least 200 million barrels (31,800,000 m{sup 3}) of oil are at risk of being unrecovered in these small fields because of inefficient recovery practices and undrained heterogeneous reservoirs. Five fields (Anasazi, Mule, Blue Hogan, Heron North, and Runway) within the Navajo Nation of southeastern Utah are being evaluated for waterflood or carbon-dioxide (CO{sub 2})-miscible flood projects based upon geological characterization and reservoir modeling. The results can be applied to other fields in the Paradox basin and the Rocky Mountain region, the Michigan and Illinois basins, and the Midcontinent. Geological characterization on a local scale focused on reservoir heterogeneity, quality, and lateral continuity as well as possible compartmentalization within each of the five project fields. This study utilized representative core and modern geophysical logs to characterize and grade each of the five fields for suitability of enhanced recovery projects. The typical vertical sequence or cycle of lithofacies from each field, as determined from conventional core, was tied to its corresponding log response. The diagenetic fabrics and porosity types found in the various hydrocarbon-bearing rocks of each field can be an indicator of reservoir flow capacity, storage capacity, and potential for water- and/or CO{sub 2}-flooding. Diagenetic histories of the various Desert Creek reservoirs were determined from 50 representative samples selected from the conventional cores of each field. Thin sections were also made of each sample for petrographic description.

    Results are presented of stuides conducted to evaluate carbon dioxide sources in the Los Angeles Basin, determine the requirements for upgrading and transmitting the gas, write the necessary material specifications, and determine where carbon dioxde may be effectively utilized as an enhanced recovery agent in oil fields, estimate recovery performance, and evaluate potential economic benefits. Study results show that there are two major sources of CO/sub 2/ in the Los Angeles Basin. Six oil refineries and one ammonia plant (all near Los Angeles Basin oil fields), have hydrogen plants with by-product streams of concentrated CO/sub 2/. The total available (uncommitted) CO/sub 2/ from these streams is about 3,000 tons per day. Six major electric power plants, all near L.A. Basin oil fields, discharge a combined total of 70,000 tons per day of CO/sub 2/ from 27 large boilers. Average CO/sub 2/ concentration in the flue gas is about 14 percent on a dry basis. CO/sub 2/ processing recommendations include modification of the existing hydrogen-CO/sub 2/ separation system, so that nitrogen is not used for stripping and therefore does not need to be removed, use propylene carbonate absorption, and use low-temperature separation. For CO/sub 2/ extraction from flue gas, monoethanolamine (MEA) absorption is recommended. Several reservoirs have been identified and are listed as prime candidates for CO/sub 2/ injection, using the major criteria of high oil saturation in the reservoir, suitable depth of the reservoir, and a good potential for zone control.

The results can be applied to other fields in the Paradox basin and the Rocky Mountain region, the Michigan and Illinois basins, and the Midcontinent. The Anasazi field was selected for the initial geostatistical modeling and reservoir simulation. A compositional simulation approach is being used to model primary depletion, waterflood, and CO{sub 2}-flood processes. During this second year of the project, team members performed the following reservoir-engineering analysis of Anasazi field: (1) relative permeability measurements of the supra-mound and mound-core intervals, (2) completion of geologic model development of the Anasazi reservoir units for use in reservoir simulation studies including completion of a series of one-dimensional, carbon dioxide-displacement simulations to analyze the carbon dioxide-displacement mechanism that could operate in the Paradox basin system of reservoirs, and (3) completion of the first phase of the full-field, three-dimensional Anasazi reservoir simulation model, and the start of the history matching and reservoir performance prediction phase of the simulation study.

    The report investigates the use of HTR modular reactors for tertiary oil recovery in the Emsland oil fields of Ruehlermoor and Georgsdorf with a view to the economic aspects of such a project. The reference plant used for the study is a HTR-2 modular reactor for combined steam and hydrogen generation. In addition, some plant variants are considered (HTR-2 and HTR-3 modular systems) also for steam generation only, in this case providing for the plants' higher steam output to be fed to the oil field, or to be used otherwise without additional cost (e.g. for electricity generation). As the Emsland oil fields are sites where the conditions of application of HTR modular systems are relatively unfavourable, the study also covers an assessment of the economic potentials of larger HTR-4 modular systems and their application at more favourable (foreign) oil fields.

    Full Text Available The second tertiary combined model experiment zone has been developed in Block B, Field L. The percolation feature of the second tertiary combined develop model shows great importance to rational and efficient development of the reservoir. In order to clearly illuminate its percolation feature, the typical reservoir numerical model is built by Eclipse, which is a reservoir numerical simulation software. The percolation features of original and added perforation interval under the second tertiary combined model are studied, and the variation features of general water-cut, recovery percentage, wellbore pressure, reservoir pressure and water saturation on condition of higher injection rate under the second tertiary combined model are analyzed. The research indicates that the second tertiary combined enhances the recovery of remaining oil on top of thick reservoir by developing and enhancing original perforation interval under water drive, then improves development results by polymer flooding, and gains higher recovery rate by synthetic action of water driver and polymer flooding.

  5. Tertiary lymphoid tissue (United States)

    Di Caro, Giuseppe; Marchesi, Federica


    Tumor-infiltrating lymphocytes influence colorectal cancer progression. We have recently documented that tertiary lymphoid tissue in the colorectal cancer microenvironment orchestrates lymphocyte infiltration and that tertiary lymphoid tissue and lymphocytes cooperate in a coordinated antitumor immune response to improve patient outcome. Thus, tertiary lymphoid tissue represents a potential target in the design of tailored immune-based therapeutic approaches. PMID:25083321

    The West Hackberry Tertiary Project is a field test of the concept that air injection can be combined with the Double Displacement Process to produce a tertiary recovery process that is both low cost and economic at current oil prices. The Double Displacement Process is the gas displacement of a water invaded oil column for the purpose of recovering tertiary oil by gravity drainage. In reservoirs with pronounced bed dip such as those found in West Hackberry and other Gulf Coast salt dome fields, reservoir performance has shown that gravity drainage recoveries average 80% to 90% of the original oil in place while waterdrive recoveries average 50% to 60% of the original oil in place. The target for tertiary oil recovery in the Double Displacement Process is the incremental oil between the 50% to 60% waterdrive recoveries and the 80% to 90% gravity drainage recoveries. In previous field tests, the Double Displacement Process has proven successful in generating tertiary oil recovery. The use of air injection in this process combines the benefits of air`s low cost and universal accessibility with the potential for accelerated oil recovery from the combustion process. If successful, this project will demonstrate that utilizing air injection in the Double Displacement Process will result in an economically viable tertiary process in reservoirs (such as Gulf Coast salt dome reservoirs) where any other tertiary process is presently uneconomic.

  8. Secondary and tertiary hyperparathyroidism. (United States)

    Jamal, Sophie A; Miller, Paul D


    We reviewed the etiology and management of secondary and tertiary hyperparathyroidism. Secondary hyperparathyroidism is characterized by an increase in parathyroid hormone (PTH) that is appropriate and in response to a stimulus, most commonly low serum calcium. In secondary hyperparathyroidism, the serum calcium is normal and the PTH level is elevated. Tertiary hyperparathyroidism is characterized by excessive secretion of PTH after longstanding secondary hyperparathyroidism, in which hypercalcemia has ensued. Tertiary hyperparathyroidism typically occurs in men and women with chronic kidney disease usually after kidney transplant. The etiology and treatment of secondary hyperparathyroidism is relatively straightforward whereas data on the management of tertiary hyperparathyroidism is limited to a few small trials with short follow-up.

  10. Visibility of natural tertiary rainbows. (United States)

    Lee, Raymond L; Laven, Philip


    Naturally occurring tertiary rainbows are extraordinarily rare and only a handful of reliable sightings and photographs have been published. Indeed, tertiaries are sometimes assumed to be inherently invisible because of sun glare and strong forward scattering by raindrops. To analyze the natural tertiary's visibility, we use Lorenz-Mie theory, the Debye series, and a modified geometrical optics model (including both interference and nonspherical drops) to calculate the tertiary's (1) chromaticity gamuts, (2) luminance contrasts, and (3) color contrasts as seen against dark cloud backgrounds. Results from each model show that natural tertiaries are just visible for some unusual combinations of lighting conditions and raindrop size distributions.

  11. Increased oil production and reserves utilizing secondary/tertiary recovery techniques on small reservoirs in the Paradox basin, Utah. Quarterly technical progress report, April 1, 1996--June 30, 1996

    Energy Technology Data Exchange (ETDEWEB)

    Allison, M.L.


    The primary objective of this project is to enhance domestic petroleum production by demonstration and technology transfer of an advanced oil recovery technology in the Paradox basin, southeastern Utah. If this project can demonstrate technical and economic feasibility, the technique can be applied to approximately 100 additional small fields in the Paradox basin alone, and result in increased recovery of 150 to 200 million barrels of oil. This project is designed to characterize five shallow-shelf carbonate reservoirs in the Pennsylvanian (Desmoinesian) Paradox Formation and choose the best candidate for a pilot demonstration project for either a waterflood or carbon dioxide (CO{sub 2}-)flood project. The field demonstration, monitoring of field performance, and associated validation activities will take place in the Paradox basin within the Navajo Nation. The results of this project will be transferred to industry and other researchers through a petroleum extension service, creation of digital databases for distribution, technical workshops and seminars, field trips, technical presentations at national and regional professional meetings, and publication in newsletters and various technical or trade journals.

  12. General introduction and recovery factors (United States)

    Verma, Mahendra K.


    IntroductionThe U.S. Geological Survey (USGS) compared methods for estimating an incremental recovery factor (RF) for the carbon dioxide enhanced oil recovery (CO2-EOR) process involving the injection of CO2 into oil reservoirs. This chapter first provides some basic information on the RF, including its dependence on various reservoir and operational parameters, and then discusses the three development phases of oil recovery—primary, second­ary, and tertiary (EOR). It ends with a brief discussion of the three approaches for estimating recovery factors, which are detailed in subsequent chapters.

  15. Fundamentals of tertiary oil recovery. Pt. 7. Polymer flooding

    Energy Technology Data Exchange (ETDEWEB)

    Herbeck, E.F.; Heitz, R.C.; Hastings, J.R.


    Polymer flooding is directed toward improving sweep efficiency by reducing the mobility ratio. Some authorities state that mobility ratio is the most important single characteristic in a waterflood. Mobility of a given fluid is the permeability of the rock to that fluid divided by the fluid's viscosity. Mobility ratio in a waterflood is the mobility of the injected water at residual oil saturation divided by the mobility of the oil at connate water saturation. A mobility ratio (M) of approx. one or less is considered favorable. Examination of the formula for mobility ratio shows that M for a waterflood can be made more favorable by any of the following: (1) decrease the effective permeability to water; (2) decrease oil viscosity; (3) increase viscosity of injected water; and/or (4) increase the effective permeability to oil.

  20. Parathyroid carcinoma in tertiary hyperparathyroidism. (United States)

    Kim, Byung Seup; Ryu, Han Suk; Kang, Kyung Ho; Park, Sung Jun


    Parathyroid carcinoma is a rare disease of unknown etiology. This study presents a case of parathyroid carcinoma in a patient with tertiary hyperparathyroidism. Despite a successful kidney transplantation, the intact parathyroid hormone (iPTH) level of the patient was elevated consistently and could not be controlled by medical therapy. Due to the development of tertiary hyperparathyroidism with bone pain and osteoporosis, subtotal parathyroidectomy was performed 4 months after the kidney transplantation. Histological evaluation revealed that one of four parathyroid lesions was a parathyroid carcinoma, while the others were diffuse hyperplasia. Postoperative laboratory studies indicated a decreased level of iPTH. A positron emission tomography-computed tomography performed 6 months after the operation revealed no evidence of local recurrence or distant metastasis. Copyright © 2013.

  1. Oil recovery technology: key to future US supply

    Energy Technology Data Exchange (ETDEWEB)

    Kastrop, J.E.


    Secondary and tertiary recovery will account for over half the oil produced in the U.S. by 1980, exclusive of the North Slope. Estimates indicate that nearly 5,000,000 bopd will be produced from these oil recovery projects while total crude production in the Lower 48 will amount to just under 10,000,000 bopd. By this time, it is anticipated that North Slope oil will reach about 2,000,000 bopd. Last yr, secondary and tertiary recovery accounted for about 30% or 3,000,000 bopd in the U.S., and both will grow significantly with demand and some economic encouragement. Tertiary projects, now estimated to present a little more than 200,000 bopd, will increase to over 400,000 bopd by 1975, then to 1,000,000 bopd by 1980. The trend is shown in graphic form.

The present paper explores the varieties of spiritual experience within A.A., with particular reference to the growth of a wing of recovery spirituality promoted within A.A. It is suggested that the essence of secular spirituality is reflected in the experience of beyond (horizontal and vertical transcendence and between (connection and mutuality and in six facets of spirituality (Release, Gratitude, Humility, Tolerance, Forgiveness, and a Sense of Being-at-home shared across religious, spiritual, and secular pathways of addiction recovery. The growing varieties of A.A. spirituality (spanning the “Christianizers” and “Seculizers” reflect A.A.’s adaptation to the larger diversification of religious experience and the growing secularization of spirituality across the cultural contexts within which A.A. is nested.

  4. Tertiary hypothyroidism in a dog

    Shiel Robert E


    Full Text Available A nine-year-old male entire Labrador was diagnosed with pituitary dependent hyperadrenocorticism. Following seven months of successful mitotane therapy, the dog presented with marked weight gain, seborrhoea and alopecia. Routine clinicopathological analyses revealed marked hypercholesterolaemia. Serum total and free thyroxine (T4 concentrations were below their respective reference ranges. Serum thyroid stimulating hormone (cTSH concentration was within reference range. TSH and thyrotropin releasing hormone (TRH response tests revealed adequate stimulation of total T4 in both, and cTSH in the latter test. Magnetic resonance imaging revealed a mass arising from the pituitary fossa, with suprasellar extension. A diagnosis of tertiary hypothyroidism was made. Following four weeks of levothyroxine therapy, circulating cholesterol concentration had declined, weight loss had ensued and dermatological abnormalities had improved. Euthanasia was performed four months later due to the development of neurological signs. A highly infiltrative pituitary adenoma, with effacement of the overlying hypothalamus was identified on post mortem examination. Tertiary hypothyroidism has not been previously reported in dogs.

  7. Radioguided parathyroidectomy for tertiary hyperparathyroidism. (United States)

    Somnay, Yash R; Weinlander, Eric; Alfhefdi, Amal; Schneider, David; Sippel, Rebecca S; Chen, Herbert


    Tertiary hyperparathyroidism (3HPT) is defined as the persistent hyperproduction of parathyroid hormone and resulting hypercalcemia after renal transplantation. Here, we examine the utility of radioguided parathyroidectomy (RGP) in patients with 3HPT. We reviewed a prospective surgery database containing 80 3HPT patients who underwent RGP from January 2001-July 2014 at our institution. We evaluated patient demographics, operative management, radioguided neoprobe utilization, and operative outcomes. Data are reported as mean ± standard error of the mean. The mean age of the patients was 52 ± 1 y, and 46% were male. A total of 69 patients had hyperplasia and received subtotal parathyroidectomy, whereas 5 patients had double adenomas and 6 patients had single adenomas. The average calcium level among 3HPT patients was 10.8 ± 0.1 mg/dL preoperatively and 8.7 ± 0.1 mg/dL postoperatively. In vivo radioguided counts normalized to background counts averaged 145 ± 4%, whereas ex vivo counts normalized to background counts averaged 69 ± 5%. All but one ex vivo count was >20%. Ectopically located glands were successfully localized in 38 patients using the gamma probe. Ex vivo percentage did not correlate with parathyroid gland weight, preoperative parathyroid hormone, or preoperative calcium. Our radioguided approach achieved normocalcemia in 96% of 3HPT patients undergoing RGP; two patients developed recurrent disease. In this series, all enlarged parathyroid glands were localized and resected using the gamma probe. Thus, RGP reliably localizes adenomatous, hyperplastic, and ectopically located glands in patients with 3HPT, resulting in high cure rate after resection. Copyright © 2015 Elsevier Inc.

  20. Economics of Tertiary Education - Challenges and dynamics of the public tertiary education in Albania

    Directory of Open Access Journals (Sweden)

    Gledian Llatja


    Full Text Available The tertiary education is a critic mechanism for the socio-economic progress, for individuals who aspire a brighter future and it is also considered an important catalyzer of the economic mobility (Department of Treasury and Department of Education, 2012, 2. Based on the positive role and impact that the tertiary education has on the sustainable development, President Obama once stated that it is of damage to treat education as a luxurious public service. In line with the general considerations about the tertiary education in the U.S. the parallel comparison with Albania comes as a direct interpretation of utopia in the education policy-making. As policies are usually drafted based on data and findings, in the case of Albania there is a lack of data on expenses on tertiary education as share of GDP. This stands also for the main limitation of the paper.

  3. Effects of tertiary treatment by fungi on organic compounds in a kraft pulp mill effluent. (United States)

    Rocha-Santos, Teresa; Ferreira, Filipe; Silva, Lurdes; Freitas, Ana Cristina; Pereira, Ruth; Diniz, Mário; Castro, Luísa; Peres, Isabel; Duarte, Armando Costa


    Pulp and paper mills generate a plethora of pollutants depending upon the type of pulping process. Efforts to mitigate the environmental impact of such effluents have been made by developing more effective biological treatment systems in terms of biochemical oxygen demand, chemical oxygen demand, colour and lignin content. This study is the first that reports an evaluation of the effects of a tertiary treatment by fungi (Pleurotus sajor caju, Trametes versicolor and Phanerochaete chrysosporium and Rhizopus oryzae) on individual organic compounds of a Eucalyptus globulus bleached kraft pulp and paper mill final effluent after secondary treatment (final effluent). The tertiary treatment with P. sajor caju, T. versicolor and P. chrysosporium and R. oryzae was performed in batch reactors, which were inoculated with separate fungi species and monitored throughout the incubation period. Samples from effluent after secondary and after tertiary treatment with fungi were analysed for both absorbance and organic compounds. The samples were extracted for organic compounds using solid-phase extraction (SPE) and analysed by gas chromatography-mass spectrometry (GC/MS). The efficiencies of the SPE procedure was evaluated by recovery tests. A total of 38 compounds (carboxylic acids, fatty alcohols, phenolic compounds and sterols) were identified and quantified in the E. globulus bleached kraft pulp mill final effluent after secondary treatment. Recoveries from the extraction procedure were between 98.2% and 99.9%. The four fungi species showed an adequate capacity to remove organic compounds and colour. Tertiary treatment with R. oryzae was able to remove 99% of organic compounds and to reduce absorbance on 47% (270 nm) and 74% (465 nm). P. sajor caju, T. versicolor and P. chrysosporium were able to remove 97%, 92% and 99% of organic compounds, respectively, and reduce 18% (270 nm) to 77% (465 nm), 39% (270 nm) to 58% (465 nm) and 31% (270 nm) to 10% (465 nm) of absorbance

    that increases the length of anesthetic recovery and causes patient dissatisfaction. The evaluation of the risk of PONV and institution of prophylactic measures aiming the well-being of patients and cost reduction are frequent in the medical literature. This observational study evaluated the incidence, risk factors, and adjustment and effectivity of the prophylaxis of PONV in the recovery room of a tertiary teaching school. METHODS: Information obtained from patients' records and questionnaires answered by patients included age, major predictive factors for PONV (female gender, history, absence of smoking, and postoperative use of opioids, prophylactic drugs administered, development of PONV, type of surgery and anesthesia, use of nitrous oxide, clinical status, and length of stay in the recovery room. RESULTS: An incidence of 18.5% of nausea and 8.5% of vomiting in the immediate postoperative period was observed. A correlation between major risk factors and the development of PONV was also observed. A correlation between those factors and prophylactic anti-emetic drugs, as well as between their use and the development of PONV, was not observed. However, a tendency to administer prophylactic medication to young female patients was observed. CONCLUSIONS: The concerns of the anesthesiologists of the institution with PONV were evident. However, the absence of correlation between risk and prophylaxis suggests an empirical and ineffective procedure. Factors that were not evaluated were suggested by the absence between PONV and the use of anti-emetic drugs. The orientation for anesthesiologists regarding more effective prophylactic measures can improve care of the population assisted.

  5. Tertiary fatty amides as diesel fuel substitutes

    Energy Technology Data Exchange (ETDEWEB)

    Serdari, Aikaterini; Lois, Euripides; Stournas, Stamoulis [National Technical Univ. of Athens, Dept. of Chemical Engineering, Athens (Greece)


    This paper presents experimental results regarding the impact of adding different tertiary amides of fatty acids to mineral diesel fuel; an assessment of the behaviour of these compounds as possible diesel fuel extenders is also included. Measurements of cetane number, cold flow properties (cloud point, pour point and CFPP), density, kinematic viscosity, flash point and distillation temperatures are reported, while initial experiments concerning the effects on particulate emissions are also described. Most of the examined tertiary fatty amides esters have very good performance and they can be easily prepared from fatty acids (biomass). Such compounds or their blends could be used as mineral diesel fuel or even fatty acid methylesters (FAME, biodiesel) substitutes or extenders. (Author)

  6. Missed injury and the tertiary trauma survey. (United States)

    Thomson, Charles B; Greaves, Ian


    Missed injury in the context of major trauma remains a persistent problem, both from a clinical and medico-legal point-of-view. Estimates of the incidence vary widely, dependent on the precise parameters of the studied population, the definition of missed injury and the extent of follow-up, but may be as high as 38%. The tertiary survey, in which formal repeated examination of the patient is undertaken after initial resuscitation and treatment have taken place, has been suggested as a way of identifying injuries not found at presentation. This paper appraises the concept of the tertiary survey, and also reviews the literature on missed injury in order to identify the risk factors, the types of injury and the reasons for error.

The removal rates of salt and sugar were as high as 99.1% and 99.5% respectively, and the removal rates of CODCr and SS were 99.3% and 96.0%, respectively after the preserved wastewater was treated by the tertiary treatment technology, which both reached the primary standard of “The Integrated Wastewater Discharge Standard” (GB8978-1996.

  8. Exploring Tertiary Students' Understanding of Covalent Bonding (United States)

    Coll, Richard K.; Treagust, David F.


    There has been little research into learners' mental models of chemical bonding at any level, let alone the tertiary level. Undergraduate and graduate students encounter a plethora of sophisticated and highly abstract mental models for chemical bonding, and this study sought to investigate if there are preferred mental models for the concept of covalent bonding for secondary, undergraduate, and graduate chemistry learners. In particular, it was of interest to see whether exposure to increasingly sophisticated mental models at different points in a chemistry education showed up in patterns of preference and use of models in interpreting common physical properties and phenomena. The study revealed that, despite evidencing expertise in a number of highly complex and mathematically sophisticated mental models, tertiary students, including graduates (MSc and PhD), show a strong preference for simple realistic mental models. Furthermore, the students struggled to use their mental models to explain the physical properties of covalently bonded substances.

    Debout, D.G.; Luttrell, P.E.; Seo, J.H.


    Regional studies of the Frio Formation along the Texas Gulf Coast were conducted to evaluate potential geothermal energy from deep, geopressured sandstone reservoirs. Published regional cross sections, unpublished cross sections provided by several major oil companies, and extensive micropaleontological and electrical-log files at the Bureau of Economic Geology served as basic data. These sections are meant to show gross regional distribution of sand and shale facies both laterally and vertically throughout the entire Tertiary section along the Texas Gulf Coast.

    Reavley Nicola J


    Full Text Available Abstract Background Heavy alcohol consumption among adolescents and young adults is an issue of significant public concern. With approximately 50% of young people aged 18-24 attending tertiary education, there is an opportunity within these settings to implement programs that target risky drinking. The aim of the current study was to survey students and staff within a tertiary education institution to investigate patterns of alcohol use, alcohol-related problems, knowledge of current National Health and Medical Research Council (NHMRC guidelines for alcohol consumption and intentions to seek help for alcohol problems. Methods Students of an Australian metropolitan university (with staff as a comparison group participated in a telephone interview. Questions related to knowledge of NHMRC guidelines, drinking behaviour, alcohol-related problems and help-seeking intentions for alcohol problems. Level of psychological distress was also assessed. Results Of the completed interviews, 774 (65% were students and 422 (35% were staff. While staff were more likely to drink regularly, students were more likely to drink heavily. Alcohol consumption was significantly higher in students, in males and in those with a history of earlier onset drinking. In most cases, alcohol-related problems were more likely to occur in students. The majority of students and staff had accurate knowledge of the current NHMRC guidelines, but this was not associated with lower levels of risky drinking. Psychological distress was associated with patterns of risky drinking in students. Conclusions Our findings are consistent with previous studies of tertiary student populations, and highlight the disconnect between knowledge of relevant guidelines and actual behaviour. There is a clear need for interventions within tertiary education institutions that promote more effective means of coping with psychological distress and improve help-seeking for alcohol problems, particularly among

    Full Text Available Speaking is considered to be difficult thing, moreover English as a foreign language. Students' performance depends on their personalities. Students who have low participation in speaking activity in the classroom lose their opportunity to practice their speaking skill which may cause poor speaking skill and achievement. However, some of students are active in speaking activity in the classroom that leads them to have good skill and achievement in speaking. This study attempts to reveal: (1 speaking strategies used by Indonesian tertiary students in terms of speaking English and strategies to improve their speaking ability, and (2 to identify speaking strategies mostly used by the students when they speak English and improve their speaking ability. This study is a descriptive research since its purpose is to describe the Indonesian tertiary students’ learning strategies in learning speaking English. The data from 15 tertiary students, who have good performance and achievement in speaking, from one of schools of higher education in Cimahi were collected using a 21 items questionnaire of a modified version of Strategy Inventory Language Learning (SILL and 5 items interview questions. The result of the study revealed that some speaking strategies are used in terms of speaking English and improve speaking ability, namely cognitive, metacognitive and compensation strategy. In the type of speaking strategy that mostly used by the student in terms of speaking English is compensation strategy, while cognitive strategy was indicated as the mostly speaking strategies used by the Indonesian tertiary students in improving their speaking ability. Considering to the study conducted, it is recommended to students that they should know what strategies that appropriate and can help them in learning speaking English. The students should be able to choose strategies they need in learning and analyze which strategies that give better effect on their own learning.

    Full Text Available Refractory coeliac disease (RCD is a rare complication of coeliac disease (CD and involves malabsorption and villous atrophy despite adherence to a strict gluten-free diet (GFD for at least 12 months in the absence of another cause. RCD is classified based on the T-cells in the intra-epithelial lymphocyte (IEL morphology into type 1 with normal IEL and type 2 with aberrant IEL (clonal by PCR (polymerase chain reaction for T cell receptors (TCR at the β/γ loci. RCD type 1 is managed with strict nutritional and pharmacological management. RCD type 2 can be complicated by ulcerative jejunitis or enteropathy associated lymphoma (EATL, the latter having a five-year mortality of 50%. Management options for RCD type 2 and response to treatment differs across centres and there have been debates over the best treatment option. Treatment options that have been used include azathioprine and steroids, methotrexate, cyclosporine, campath (an anti CD-52 monoclonal antibody, and cladribine or fluadribine with or without autologous stem cell transplantation. We present a tertiary centre’s experience in the treatment of RCD type 2 where treatment with prednisolone and azathioprine was used, and our results show good response with histological recovery in 56.6% of treated individuals.

  16. Analysis of heavy-oil immiscible CO/sub 2/ tertiary coreflood data

    Energy Technology Data Exchange (ETDEWEB)

    Mayer, E.H.; Earlougher, R.C. Sr.; Spivak, A.; Costa, A.


    This paper describes the results of a series of tertiary, immiscible, CO/sub 2/ corefloods of Wilmington field Pliocene reservoir rock containing heavy oil (+- 14/sup 0/ API (+-0.97 g/cm/sup 3/) and +-480 cp (+-480 mPa . s)). An initial set of corefloods defined the recovery potential of the CO/sub 2/ injection, while a series of later tests served to define the process more accurately as applied in the field. In an attempt to understand the displacement mechanism, simulator matching of one of the later, more refined groups of corefloods was performed. The corefloods and simulator work indicate that the incremental recovery is more than can be accounted for by oil-viscosity reduction and crude-oil swelling. The improved performance is attributed to more favorable displacement characteristics and the presence of a free gas saturation in the cores.

    In October 2009, the project partners began a 36-month effort to develop an innovative, commercial-scale demonstration project incorporating state-of-the-art waste heat recovery technology at Clean Harbors, Inc., a large hazardous waste incinerator site located in Deer Park, Texas. With financial support provided by the U.S. Department of Energy, the Battleground Energy Recovery Project was launched to advance waste heat recovery solutions into the hazardous waste incineration market, an area that has seen little adoption of heat recovery in the United States. The goal of the project was to accelerate the use of energy-efficient, waste heat recovery technology as an alternative means to produce steam for industrial processes. The project had three main engineering and business objectives: Prove Feasibility of Waste Heat Recovery Technology at a Hazardous Waste Incinerator Complex; Provide Low-cost Steam to a Major Polypropylene Plant Using Waste Heat; and Create a Showcase Waste Heat Recovery Demonstration Project.

  18. Carbon dioxide enhanced oil recovery performance according to the literature (United States)

    Olea, Ricardo A.


    IntroductionThe need to increase the efficiency of oil recovery and environmental concerns are bringing to prominence the use of carbon dioxide (CO2) as a tertiary recovery agent. Assessment of the impact of flooding with CO2 all eligible reservoirs in the United States not yet undergoing enhanced oil recovery (EOR) requires making the best possible use of the experience gained in 40 years of applications. Review of the publicly available literature has located relevant CO2-EOR information for 53 units (fields, reservoirs, pilot areas) in the United States and 17 abroad.As the world simultaneously faces an increasing concentration of CO2 in the atmosphere and a higher demand for fossil fuels, the CO2-EOR process continues to gain popularity for its efficiency as a tertiary recovery agent and for the potential for having some CO2 trapped in the subsurface as an unintended consequence of the enhanced production (Advanced Resources International and Melzer Consulting, 2009). More extensive application of CO2-EOR worldwide, however, is not making it significantly easier to predict the exact outcome of the CO2 flooding in new reservoirs. The standard approach to examine and manage risks is to analyze the intended target by conducting laboratory work, running simulation models, and, finally, gaining field experience with a pilot test. This approach, though, is not always possible. For example, assessment of the potential of CO2-EOR at the national level in a vast country such as the United States requires making forecasts based on information already available.Although many studies are proprietary, the published literature has provided reviews of CO2-EOR projects. Yet, there is always interest in updating reports and analyzing the information under new perspectives. Brock and Bryan (1989) described results obtained during the earlier days of CO2-EOR from 1972 to 1987. Most of the recovery predictions, however, were based on intended injections of 30 percent the size of

  19. Stereoinversion of tertiary alcohols to tertiary-alkyl isonitriles and amines. (United States)

    Pronin, Sergey V; Reiher, Christopher A; Shenvi, Ryan A


    The SN2 reaction (bimolecular nucleophilic substitution) is a well-known chemical transformation that can be used to join two smaller molecules together into a larger molecule or to exchange one functional group for another. The SN2 reaction proceeds in a very predictable manner: substitution occurs with inversion of stereochemistry, resulting from the 'backside attack' of the electrophilic carbon by the nucleophile. A significant limitation of the SN2 reaction is its intolerance for tertiary carbon atoms: whereas primary and secondary alcohols are viable precursor substrates, tertiary alcohols and their derivatives usually either fail to react or produce stereochemical mixtures of products. Here we report the stereochemical inversion of chiral tertiary alcohols with a nitrogenous nucleophile facilitated by a Lewis-acid-catalysed solvolysis. The method is chemoselective against secondary and primary alcohols, thereby complementing the selectivity of the SN2 reaction. Furthermore, this method for carbon-nitrogen bond formation mimics a putative biosynthetic step in the synthesis of marine terpenoids and enables their preparation from the corresponding terrestrial terpenes. We expect that the general attributes of the methodology will allow chiral tertiary alcohols to be considered viable substrates for stereoinversion reactions.

    Rowe, Michael; Serowik, Kristin L; Ablondi, Karen; Wilber, Charles; Rosen, Marc I


    Social recovery and external money management are important approaches in contemporary mental health care, but little research has been done on the relationship between the two or on application of recovery principles to money management for people at risk of being assigned a representative payee or conservator. Out of 49 total qualitative interviews, 25 transcripts with persons receiving Social Security insurance or Social Security disability insurance who were at risk of being assigned a money manager were analyzed to assess the presence of recognized recovery themes. The recovery principles of self-direction and responsibility were strong themes in participant comments related to money management. Money management interventions should incorporate peoples' recovery-related motivations to acquire financial management skills as a means to direct and assume responsibility for one's finances. Staff involved in money management should receive training to support client's recovery-related goals. (PsycINFO Database Record (c) 2013 APA, all rights reserved).

    Full Text Available The tertiary oil recovery methods like alkaline, surfactant and polymer (ASP flooding are very perspective in order to achieve the synergetic effect out of the different impacts which are caused by these chemicals, which affect oil and water filtration in the reservoir and increase oil recovery. In this communication, we consider the applicability of hydrophobically modified polyampholyte – poly(hexadecylaminocrotonatebetaine (PHDACB as ASP flooding agent for recovery of oil from Karazhanbas oilfield. As “polysoap”, the aqueous solution of PHDACB dissolved in aqueous KOH was used. This system combines the advantages of alkaline, surfactant and polymer and exhibits the synergistic effect. The laboratory results showed that the ASP flooding considerably increases the oil recovery in addition to water flooding. In perspective, the ASP flooding may substitute the steam injection and other thermal enhanced oil recovery (EOR technologies.

    When tertiary health centers face capacity constraint, one feasible strategy to meet service demand is outsourcing clinical services to qualified community providers. Clinical outsourcing enables tertiary health centers to meet the expectations of service timeliness and provides good opportunities to collaborate with other health care providers. However, outsourcing may result in dependence and loss of control for the tertiary health centers. Other parties involved in clinical outsourcing such as local partners, patients, and payers may also encounter potential risks as well as enjoy benefits in an outsourcing arrangement. Recommendations on selecting potential outsourcing partners are given to minimize the risks associated with an outsourcing contract. Copyright (c) 2006 John Wiley & Sons, Ltd.

  4. The Tertiary tectonics of the southeast Asia

    Energy Technology Data Exchange (ETDEWEB)

    Honza, Eiichi (Geological Survey of Japan, Tsukuba (Japan))


    Most of the terranes in eastern Asia appear to be relics of arcs, oceanic islands, and subduction complexes. They have collided and accreted from the inner (northwestern) side in China since the Silurian. They are characterized by three stages of Pacific and Tethys evolution. The first collision is related to the Pacific domain in the Permian in which these movements are not clearly reconstructed. The second collision is related to the closure of the Paleo-Tethys in the Late Triassic to Early Jurassic. The third is related to closure of the Neo-Tethys and the subsequent collision of India in the Tertiary. Southeast Asia is in one of the most enigmatic plate boundaries in the world, forming many small plates, collisions, and consumptions. This complication is also suggested to be a result of the northward movement of Australia since its break-up from Gondwanaland in the Cretaceous. During their evolution, most of them have associated with arcs. These arcs also have formed superimpositions on the older exotic blocks of terranes. They are reconstructed on the base of the regular duration on the formation of arcs and backarc basins, which can be seen in the Western Pacific Arc Chain.

    Full Text Available BACKGROUND Hyponatraemia is defined as a serum sodium level less than 135 mEq/L. High mortality among the patients of hyponatraemia is secondary to the underlying medical condition. Frequency is high in elderly patients. MATERIALS AND METHODS The study was conducted at a tertiary care centre (Basaveshwar Teaching and General Hospital, Gulbarga, from the period September 2014 to August 2016. These patients were evaluated for the underlying cause of hyponatraemia, which included detailed history and physical examination followed by appropriate laboratory investigations. Patients were followed up till the hyponatraemia was treated or patients were discharged from the hospital. RESULTS 100 patients of hyponatraemia were included in the study. 46% of the patients were asymptomatic. 33% patients had lethargy, 28% patients had postural dizziness and 19% had abnormal behaviour. Overall incidence of hyponatraemia was 4.58% in the hospitalised population, whereas its incidence in ICU patients was 22.4%. Twelve patients of symptomatic severe hyponatraemia were treated with hypertonic saline infusion, 25% patients were given loop diuretics with oral supplementation of sodium chloride for free water excretion in SIADH cases and in patients with hypervolaemia, hyponatraemia, fluid restriction was advised to 44 patients, oral supplementation of sodium chloride was given in 36 patients and 64 patients received normal saline. 9 patients included in the study died, 5 of which had advanced cirrhosis of liver as underlying cause. One patient developed Osmotic Demyelination Syndrome (ODS. CONCLUSION The possible cause of hyponatraemia should always be sought as outcome in severe hyponatraemia is governed by aetiology, and not by the serum sodium level. Treatment of severe symptomatic hyponatraemia with hypertonic saline is safe if recommendation for the rate of correction of hyponatraemia is strictly followed.

  3. A Factor Analytic Investigation of the Person-in-Recovery and Provider Versions of the Revised Recovery Self-Assessment (RSA-R). (United States)

    Konkolÿ Thege, Barna; Ham, Elke; Ball, Laura C


    Recovery is understood as living a life with hope, purpose, autonomy, productivity, and community engagement despite a mental illness. The aim of this study was to provide further information on the psychometric properties of the Person-in-Recovery and Provider versions of the Revised Recovery Self-Assessment (RSA-R), a widely used measure of recovery orientation. Data from 654 individuals were analyzed, 519 of whom were treatment providers (63.6% female), while 135 were inpatients (10.4% female) of a Canadian tertiary-level psychiatric hospital. Confirmatory and exploratory techniques were used to investigate the factor structure of both versions of the instrument. Results of the confirmatory factor analyses showed that none of the four theoretically plausible models fit the data well. Principal component analyses could not replicate the structure obtained by the scale developers either and instead resulted in a five-component solution for the Provider and a four-component solution for the Person-in-Recovery version. When considering the results of a parallel analysis, the number of components to retain dropped to two for the Provider version and one for the Person-in-Recovery version. We can conclude that the RSA-R requires further revision to become a psychometrically sound instrument for assessing recovery-oriented practices in an inpatient mental health-care setting.

  4. Seawater Chemistry Across Cretaceous-Tertiary Boundary (United States)

    Misra, S.; Turchyn, A. V.


    Continental weathering is recognized as one of the primary mechanisms moderating the concentration of CO2 in the atmosphere. Past carbon cycle perturbations, often associated with mass extinction events, recovered on a timescale of hundreds of thousands of years, broadly consistent with enhanced chemical weathering being the key moderating process. Since chemical weathering of continental rocks controls the delivery of cations to the oceans, records of seawater cation chemistry provide a powerful archive of this interplay and feedback between climate and weathering.The Cretaceous-Paleogene (K-Pg) boundary at 65.6 Ma is the last major mass extinction event. The two accepted drivers of K-Pg events were the geologically coeval eruption of Deccan Trap continental flood basalts and the meteorite impact at Chicxulub. The Chicxulub impact happened during a second pulse of Deccan traps volcanism. Thus, teasing apart the timing and dominant driver of the mass extinction and the recovery remains enigmatic. A key feature of the K-Pg event is the transient acidification of the global surface ocean that drove the collapse of the oceanic ecosystem. This surface ocean acidification was caused by `geologically instantaneous' influx of large quantities of acidic gases (viz. CO2, SO2) to the ocean-atmosphere system. We will present high-resolution records of Li, B, Mg, and Ca isotope (δ7Li, δ11B, δ26Mg, and δ44Ca, respectively) measured in single species foraminifera across the K-Pg boundary to assess the perturbation and the subsequent continental weathering feedback. The unique aspect of the proposed research is in the first direct reconstruction of seawater isotopic composition of elements intimately linked to the continental weathering cycle (Li, Mg, and Ca), and the carbon budget of the ocean-atmosphere system (Boron) across an event of rapid climate transition and recovery. Moreover, this will allow to fingerprint the timing of the acidic gas input to the atmosphere and to

  8. The equity imperative in tertiary education: Promoting fairness and efficiency (United States)

    Salmi, Jamil; Bassett, Roberta Malee


    While the share of the tertiary education age cohort (19-25) which is being given the opportunity to study has increased worldwide over the past two decades, this does not in fact translate into reduced inequality. For many young people, especially in the developing world, major obstacles such as disparities in terms of gender, minority population membership or disabilities as well as academic and financial barriers are still standing in their way. The authors of this article propose a conceptual framework to analyse equity issues in tertiary education and document the scope, significance and consequences of disparities in tertiary education opportunities. They throw some light on the main determinants of these inequalities and offer suggestions about effective equity promotion policies directed towards widening participation and improving the chances of success of underprivileged youths in order to create societies which uphold humanistic values.

  9. Spontaneous recovery from acalculia. (United States)

    Basso, Anna; Caporali, Alessandra; Faglioni, Pietro


    A topic much considered in research on acalculia was its relationship with aphasia. Far less attention has been given to the natural course of acalculia. In this retrospective study, we examined the relationship between aphasia and acalculia in an unselected series of 98 left-brain-damaged patients and the spontaneous recovery from acalculia in 92 acalculic patients with follow-up. There was a significant association between aphasia and acalculia although 19 participants exhibited aphasia with no acalculia and six acalculia with no aphasia. We observed significant improvement between a first examination carried out between 1 and 5 months post-onset and a second examination carried out between 3 and 11 months later (mean: 5 months). The mechanisms of spontaneous recovery are discussed.

  10. Recovery in aluminium

    DEFF Research Database (Denmark)

    Gundlach, Carsten


    In the present thesis the development of a unique experimental method for volume characterisation of individual embedded crystallites down to a radius of 150 nm is presented. This method is applied to in-situ studies of recovery in aluminium. The method is an extension of 3DXRD microscopy, an X...... by the combined use of X-ray micro focusing optics, new scanning algorithms and the use of foils. The ratio of foil thickness to crystallite size should be at least 10 such that the central ones are situated in a bulk environment. To avoid thermal drifts, gold reference markers are deposited onto the sample...... are represented as strings. To identify the strings a combination of a 5D connected component type algorithm and multi-peak fitting was found to be superior. The first use of the method was a study of recovery of a deformed aluminium alloy (AA1050). The aluminium alloy was deformed by cold rolling to a thickness...

Exports of tertiary education services from the Queensland economy now rival wool and wheat in importance. A number of marketing and policy issues arise in the context of further change in th...

  14. Sexual harassment in tertiary institutions: A comparative perspective

    Directory of Open Access Journals (Sweden)

    Joseph Janice


    Full Text Available Sexual harassment is not a new phenomenon in tertiary institutions. It has been receiving considerable attention in research and the media and public awareness has increased dramatically. However, the term sexual harassment is not used uniformly across the globe because countries have defined it differently. Consequently, prevalence of sexual harassment in education varies across cultures. This paper examines sexual harassment from a comparative perspective. It specifically focuses on the definition of sexual harassment, incidence of sexual harassment of students in tertiary institutions, effects of sexual harassment on victims; and victims’ responses to sexual harassment. It also offers suggestions for curtailing sexual harassment in these institutions.

  15. Recovery From Comorbidity

    Directory of Open Access Journals (Sweden)

    Mathew Carter


    Full Text Available Comorbidity among mood, anxiety, and alcohol disorders is common and burdensome, affecting individuals, families, and public health. A systematic and integrative review of the literature across disciplines and research methodologies was performed. Supradisciplinary approaches were applied to the review and the ensuing critical appraisal. Definitions, measurement, and estimation are controversial and inconstant. Recovery from comorbidity cannot be easily extricated from a sociocultural milieu. Methodological challenges in quantitative and qualitative research and across disciplines are many and are discussed. The evidence supporting current treatments is sparse and short-term, and modalities operating in isolation typically fail. People easily fall into the cracks between mental health and addiction services. Clinicians feel untrained and consumers bear the brunt of this: Judgmental and moralistic interactions persist and comorbidity is unrecognized in high-risk populations. Competing historical paradigms of mental illness and addiction present a barrier to progress and reductionism is an impediment to care and an obstacle to the integration and interpretation of research. What matters to consumers is challenging to quantify but worth considering: Finding employment, safe housing, and meaning are crucial to recovery. Complex social networks and peer support in recovery are important but poorly understood. The focus on modalities of limited evidence or generalizability persists in literature and practice. We need to consider different combinations of comorbidity, transitions as opposed to dichotomies of use or illness, and explore the long-term view and emic perspectives.

  16. Tertiary syphilis in the lumbar spine: a case report. (United States)

    Bai, Yang; Niu, Feng; Liu, Lidi; Sha, Hui; Wang, Yimei; Zhao, Song


    The incidence of tertiary syphilis involvement in the spinal column with destructive bone lesions is very rare. It is difficult to establish the correct diagnosis from radiographs and histological examination alone. Limited data are available on surgical treatment to tertiary syphilitic spinal lesions. In this article, we report a case of tertiary syphilis in the lumbar spine with osteolytic lesions causing cauda equina compression. A 44-year-old man who suffered with low back pain for 6 months and progressive radiating pain at lower extremity for 1 week. Radiologic findings showed osteolytic lesion and new bone formation in the parts of the bodies of L4 and L5. Serum treponema pallidum hemagglutination (TPHA) test was positive. A surgery of posterior debridement, interbody and posterolateral allograft bone fusion with instrumentation from L3 to S1 was performed. The low back pain and numbness abated after operation. But the follow-up radiographs showed absorption of the bone grafts and failure of instrumentation. A Charcot's arthropathy was formed between L4 and L5. It is challenging to diagnose the tertiary syphilis in the spine. Surgery is a reasonable auxiliary method to antibiotic therapy for patients who suffered with neuropathy. Charcot's arthropathy should be considered as an operative complication.

  19. Microstructural Characterization of Alloy 617 Crept into the Tertiary Regime

    Energy Technology Data Exchange (ETDEWEB)

    Lillo, Thomas Martin [Idaho National Laboratory; Wright, Richard Neil [Idaho National Laboratory


    The microstructure of Alloy 617 was characterized following creep tests interrupted at total creep strains ranging from 2-20%. A range of creep temperatures (750-1000oC) and initial creep stresses (10-145 MPa) produced creep test durations ranging from 1 to 5800 hours. Image analysis of optical photomicrographs on longitudinal sections of the gage length was used to document the fraction of creep porosity as a function of creep parameters. Creep porosity was negligible below tertiary creep strains of 10% and increased with tertiary creep strain, thereafter. For a given temperature and total creep strain, creep porosity increased with decreasing creep stress. Creep porosity increased linearly with duration of the creep experiment. TEM performed on the gage sections did not reveal significant creep cavity formation on grain boundaries at the sub-micron level. It was concluded that the onset of tertiary creep did not result from creep cavitation and more likely arose due to the formation of low energy dislocation substructures with increasing tertiary strain.

    A method is described for recovering uranium values from uranium bearing phosphate solutions such as are encountered in the manufacture of phosphate fertilizers. The solution is first treated with a reducing agent to obtain all the uranium in the tetravalent state. Following this reduction, the solution is treated to co-precipitate the rcduced uranium as a fluoride, together with other insoluble fluorides, thereby accomplishing a substantially complete recovery of even trace amounts of uranium from the phosphate solution. This precipitate usually takes the form of a complex fluoride precipitate, and after appropriate pre-treatment, the uranium fluorides are leached from this precipitate and rccovered from the leach solution.

  12. Favorability for uranium in tertiary sedimentary rocks, southwestern Montana

    Energy Technology Data Exchange (ETDEWEB)

    Wopat, M A; Curry, W E; Robins, J W; Marjaniemi, D K


    Tertiary sedimentary rocks in the basins of southwestern Montana were studied to determine their favorability for potential uranium resources. Uranium in the Tertiary sedimentary rocks was probably derived from the Boulder batholith and from silicic volcanic material. The batholith contains numerous uranium occurrences and is the most favorable plutonic source for uranium in the study area. Subjective favorability categories of good, moderate, and poor, based on the number and type of favorable criteria present, were used to classify the rock sequences studied. Rocks judged to have good favorability for uranium deposits are (1) Eocene and Oligocene strata and undifferentiated Tertiary rocks in the western Three Forks basin and (2) Oligocene rocks in the Helena basin. Rocks having moderate favorability consist of (1) Eocene and Oligocene strata in the Jefferson River, Beaverhead River, and lower Ruby River basins, (2) Oligocene rocks in the Townsend and Clarkston basins, (3) Miocene and Pliocene rocks in the Upper Ruby River basin, and (4) all Tertiary sedimentary formations in the eastern Three Forks basin, and in the Grasshopper Creek, Horse Prairie, Medicine Lodge Creek, Big Sheep Creek, Deer Lodge, Big Hole River, and Bull Creek basins. The following have poor favorability: (1) the Beaverhead Conglomerate in the Red Rock and Centennial basins, (2) Eocene and Oligocene rocks in the Upper Ruby River basin, (3) Miocene and Pliocene rocks in the Townsend, Clarkston, Smith River, and Divide Creek basins, (4) Miocene through Pleistocene rocks in the Jefferson River, Beaverhead River, and Lower Ruby River basins, and (5) all Tertiary sedimentary rocks in the Boulder River, Sage Creek, Muddy Creek, Madison River, Flint Creek, Gold Creek, and Bitterroot basins.

  13. History of Somatization is Associated with Prolonged Recovery from Concussion (United States)

    Root, Jeremy M; Zuckerbraun, Noel S.; Wang, Li; Winger, Dan; Brent, David; Kontos, Anthony; Hickey, Robert


    Objective To determine the association between a history of somatization and prolonged concussion symptoms, including sex differences in recovery. Study design A prospective cohort study of 10–18 year olds with an acute concussion was conducted from July 2014 to April 2015 at a tertiary care pediatric emergency department. 120 subjects completed the validated Children’s Somatization Inventory (CSI) for pre-injury somatization assessment and Post-Concussion Symptoms Score (PCSS) at diagnosis. PCSS was re-assessed by phone at 2- and 4-weeks. CSI was assessed in quartiles with a generalized estimating equation model to determine relationship of CSI to PCSS over time. Results The median age of our study participants was 13.8 years (interquartile range: 11.5, 15.8), 60% male, with analyses carried out separately for each sex. Our model showed a positive interaction between total CSI score, PCSS and time from concussion for females p somatization had higher PCSS than the other three CSI quartiles at each time point (B −26.7 to −41.1, p-values somatization had higher concussion symptom scores over time. Females in the highest somatization quartile had prolonged concussion recovery with persistently high symptom scores at 4 weeks. Somatization may contribute to sex differences in recovery, and assessment at the time of concussion may help guide management and target therapy. PMID:27059916

  14. Factors influencing successful implementation of enhanced oil recovery projects

    Directory of Open Access Journals (Sweden)

    Karović-Maričić Vesna


    Full Text Available Tertiary methods in oil production process called 'Enhanced Oil recovery methods' (EOR are mostly applied in mature oil fields with declining production trend after primary and secondary recovery methods or immediately after primary production phase. These 'Enhanced Oil Recovery' methods implies injection of gases or fluids to mobilize residual oil captured in reservoir rock due to presence of strong viscous and capillary forces and high value of interfacial tension between fluid and rock. Depending on the type of injected fluid, production mechanism, as well as an approach to implementation, EOR methods are divided into thermal methods, chemical methods, miscible/immiscible gas injection methods and other methods that so far have an experimental application. The paper analyzes the key factors influencing the successful implementation of EOR projects: phases of EOR project implementation, the price of crude oil at the world market as a criterion for the beginning and the justification for EOR process application and development of new technologies for more efficient process realization.

  18. American tertiary clinic-referred bipolar II disorder versus bipolar I disorder associated with hastened depressive recurrence. (United States)

    Dell'Osso, Bernardo; Shah, Saloni; Do, Dennis; Yuen, Laura D; Hooshmand, Farnaz; Wang, Po W; Miller, Shefali; Ketter, Terence A


    Bipolar disorder (BD) is a chronic, frequently comorbid condition characterized by high rates of mood episode recurrence and suicidality. Little is known about prospective longitudinal characterization of BD type II (BD II) versus type I (BD I) in relation to time to depressive recurrence and recovery from major depressive episode. We therefore assessed times to depressive recurrence/recovery in tertiary clinic-referred BD II versus I patients. Outpatients referred to Stanford BD Clinic during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and with Clinical Monitoring Form during up to 2 years of naturalistic treatment. Prevalence and clinical correlates of bipolar subtype in recovered (euthymic ≥8 weeks) and depressed patients were assessed. Kaplan-Meier analyses assessed the relationships between bipolar subtype and longitudinal depressive severity, and Cox proportional hazard analyses assessed the potential mediators. BD II versus BD I was less common among 105 recovered (39.0 vs. 61.0%, p = 0.03) and more common among 153 depressed (61.4 vs. 38.6%, p = 0.006) patients. Among recovered patients, BD II was associated with 6/25 (24.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics and hastened depressive recurrence (p = 0.015). Among depressed patients, BD II was associated with 8/25 (33.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics, but only non-significantly associated with delayed depressive recovery. BD II versus BD I was significantly associated with current depression and hastened depressive recurrence, but only non-significantly associated with delayed depressive recovery. Research on bipolar subtype relationships with depressive recurrence/recovery is warranted to enhance clinical management of BD patients.

  19. Ear for recovery: protocol for a prospective study on parent-child communication and psychological recovery after paediatric injury. (United States)

    Alisic, Eva; Barrett, Anna; Bowles, Peter; Babl, Franz E; Conroy, Rowena; McClure, Roderick J; Anderson, Vicki; Mehl, Matthias R


    One in six children who have been admitted to hospital with an injury develop persistent stress symptoms that put their development at risk. Parents play a crucial role in children's psychological recovery, however, it is unknown how specific parenting behaviours can help or hinder. We aim to describe the nature and quantity of parent-child communication after a child has been injured, and to examine how these interactions are related to children's psychological recovery. We are conducting a prospective observational study among children aged 3-16 years, who have been admitted to a tertiary children's hospital with a serious injury. Data collection involves a naturalistic observation of spontaneous, everyday parent-child communication at home, shortly after discharge, and an assessment of children's psychological recovery at 6 weeks and 3 months post-injury. Main analyses comprise descriptive statistics, cluster analysis and analyses of variance. This study has been approved by the Human Research Ethics Committee of the Royal Children's Hospital Melbourne (33103) and Monash University Human Research Ethics Committee (CF13/2515-2013001322). We aim to disseminate the findings through international peer-reviewed journals, international conferences and social media. Participants will be sent a summary of the overall study findings.

  20. Teaching recovery to medical students.

    LENUS (Irish Health Repository)

    Feeney, Larkin


    Community mental health services are evolving toward more holistic, patient-centered, recovery-based practices. This change necessitates an attitudinal shift from mental health workers, and training in recovery principles is helpful in achieving this change. Medical students often have narrow, doctor-centered concepts of mental health care. Traditional clinical placements in psychiatry do little to address this. We evaluated a recovery-focused teaching program for medical students in psychiatry.

  1. Business recovery: an assessment framework. (United States)

    Stevenson, Joanne R; Brown, Charlotte; Seville, Erica; Vargo, John


    This paper presents a Business Recovery Assessment Framework (BRAF) to help researchers and practitioners design robust, repeatable, and comparable studies of business recovery in various post-disruption contexts. Studies assessing business recovery without adequately considering the research aims, recovery definitions, and indicators can produce misleading findings. The BRAF is composed of a series of steps that guide the decisions that researchers need to make to ensure: (i) that recovery is indeed being measured; (ii) that the indicators of recovery that are selected align with the objectives of the study and the definition of recovery; and, where necessary, (iii) that appropriate comparative control variables are in place. The paper draws on a large dataset of business surveys collected following the earthquakes in Canterbury, New Zealand, on 4 September 2010 and 22 February 2011 to demonstrate the varied conclusions that different recovery indicators can produce and to justify the need for a systematic approach to business recovery assessments. © 2017 The Author(s).

    Ernst, Timothy C.; Zigan, James A.


    A waste heat recovery system includes a Rankine cycle (RC) circuit having a pump, a boiler, an energy converter, and a condenser fluidly coupled via conduits in that order, to provide additional work. The additional work is fed to an input of a gearbox assembly including a capacity for oil by mechanically coupling to the energy converter to a gear assembly. An interface is positioned between the RC circuit and the gearbox assembly to partially restrict movement of oil present in the gear assembly into the RC circuit and partially restrict movement of working fluid present in the RC circuit into the gear assembly. An oil return line is fluidly connected to at least one of the conduits fluidly coupling the RC components to one another and is operable to return to the gear assembly oil that has moved across the interface from the gear assembly to the RC circuit.

  7. Recovery in soccer : part ii-recovery strategies. (United States)

    Nédélec, Mathieu; McCall, Alan; Carling, Chris; Legall, Franck; Berthoin, Serge; Dupont, Gregory


    In the formerly published part I of this two-part review, we examined fatigue after soccer matchplay and recovery kinetics of physical performance, and cognitive, subjective and biological markers. To reduce the magnitude of fatigue and to accelerate the time to fully recover after completion, several recovery strategies are now used in professional soccer teams. During congested fixture schedules, recovery strategies are highly required to alleviate post-match fatigue, and then to regain performance faster and reduce the risk of injury. Fatigue following competition is multifactorial and mainly related to dehydration, glycogen depletion, muscle damage and mental fatigue. Recovery strategies should consequently be targeted against the major causes of fatigue. Strategies reviewed in part II of this article were nutritional intake, cold water immersion, sleeping, active recovery, stretching, compression garments, massage and electrical stimulation. Some strategies such as hydration, diet and sleep are effective in their ability to counteract the fatigue mechanisms. Providing milk drinks to players at the end of competition and a meal containing high-glycaemic index carbohydrate and protein within the hour following the match are effective in replenishing substrate stores and optimizing muscle-damage repair. Sleep is an essential part of recovery management. Sleep disturbance after a match is common and can negatively impact on the recovery process. Cold water immersion is effective during acute periods of match congestion in order to regain performance levels faster and repress the acute inflammatory process. Scientific evidence for other strategies reviewed in their ability to accelerate the return to the initial level of performance is still lacking. These include active recovery, stretching, compression garments, massage and electrical stimulation. While this does not mean that these strategies do not aid the recovery process, the protocols implemented up until

  8. Is the sword moss (Bryoxiphium) a preglacial Tertiary relict? (United States)

    Patiño, Jairo; Goffinet, Bernard; Sim-Sim, Manuela; Vanderpoorten, Alain


    The disjunction of floras between East Asia, Southeast North America, West North America, and Southwest Eurasia has been interpreted in terms of the fragmentation of a once continuous mixed mesophytic forest that occurred throughout the Northern Hemisphere due to the climatic and geological changes during the late Tertiary. The sword moss, Bryoxiphium, exhibits a distribution that strikingly resembles that of the mesophytic forest elements such as Liriodendron and is considered as the only living member of an early Tertiary flora in Iceland. These hypotheses are tested here using molecular dating analyses and ancestral area estimations. The results suggest that the extant range of Bryoxiphium results from the fragmentation of a formerly wider range encompassing North America and Southeast Asia about 10 million years ago. The split of continental ancestral populations is too recent to match with a continental drift scenario but is spatially and temporally remarkably congruent with that observed in Tertiary angiosperm relict species. The timing of the colonization of Iceland from Macaronesian ancestors, about two million years ago, is, however, incompatible with the hypothesis that Bryoxiphium is the only living member of an early Tertiary flora of the island. Alaska was recurrently colonized from East Asia. The ability of Bryoxiphium to overcome large oceanic barriers is further evidenced by its occurrence on remote oceanic archipelagos. In particular, Madeira was colonized twice independently from American and East Asian ancestors, respectively. The striking range disjunction of Bryoxiphium is interpreted in terms of its mating system, as the taxon exhibits a very singular pattern of spatial segregation of the sexes.

  11. Enzymes for Enhanced Oil Recovery (EOR)

    Energy Technology Data Exchange (ETDEWEB)

    Nasiri, Hamidreza


    enzymes on interactions in the oil/brine/solid system was studied. It was found that enzymes can change the adhesion behavior of the crude oil on glass surfaces from adhesion to non-adhesion when they are added to the brine solution. This was confirmed by contact angle measurements, which showed that contact angles became more water-wet (i.e. decreased) after exposure to enzyme solutions. Possible mechanisms giving rise to these observations, including catalysis of ester hydrolysis and enzyme adsorption, were discussed and tested. An experimental study of changes in oil-water interfacial properties by addition of enzymes and proteins, including measurements of interfacial tension and electrophoretic mobility, has been performed. It was found that the effect of enzymes on oil-water properties is minor compared to their effect on oil-water-solid properties. Their contribution to change interfacial tension between oil and water is not significant while they affect the electrophoretic mobility of emulsified oil in enzyme-brine solution to some extent. Attempts were also made to study changes in both oil and water phase composition after equilibration with enzymes. However, since the chemical composition of crude oil is highly complex, a model oil was used in some of the experiments. The model oil was chosen to be a water insoluble ester (ethyl decanoate) solved in mineral oil in an effort to verify the possible role of catalysis of ester hydrolysis. Dynamic core displacements using sandstone and carbonate rocks were conducted to show the potential of improved oil recovery by enzyme- and combined enzyme-surfactant flooding. Most of the core flooding experiments commenced with water flooding from initial water saturation, Swi, (established with synthetic sea water) which will be referred to as secondary mode displacements. Accordingly, tertiary oil recovery processes were used to describe injection of enzyme and/or enzyme-surfactant solutions from residual oil saturation, Sor

  12. Application of decline curve analysis to estimate recovery factors for carbon dioxide enhanced oil recovery (United States)

    Jahediesfanjani, Hossein


    IntroductionIn the decline curve analysis (DCA) method of estimating recoverable hydrocarbon volumes, the analyst uses historical production data from a well, lease, group of wells (or pattern), or reservoir and plots production rates against time or cumu­lative production for the analysis. The DCA of an individual well is founded on the same basis as the fluid-flow principles that are used for pressure-transient analysis of a single well in a reservoir domain and therefore can provide scientifically reasonable and accurate results. However, when used for a group of wells, a lease, or a reservoir, the DCA becomes more of an empirical method. Plots from the DCA reflect the reservoir response to the oil withdrawal (or production) under the prevailing operating and reservoir conditions, and they continue to be good tools for estimating recoverable hydrocarbon volumes and future production rates. For predicting the total recov­erable hydrocarbon volume, the DCA results can help the analyst to evaluate the reservoir performance under any of the three phases of reservoir productive life—primary, secondary (waterflood), or tertiary (enhanced oil recovery) phases—so long as the historical production data are sufficient to establish decline trends at the end of the three phases.

  13. Salt Contribution to RNA Tertiary Structure Folding Stability (United States)

    Tan, Zhi-Jie; Chen, Shi-Jie


    Accurate quantification of the ionic contribution to RNA folding stability could greatly enhance our ability to understand and predict RNA functions. Recently, motivated by the potential importance of ion correlation and fluctuation in RNA folding, we developed the tightly bound ion (TBI) model. Extensive experimental tests showed that the TBI model can lead to better treatment of multivalent ions than the Poisson-Boltzmann equation. In this study, we use the model to quantify the contribution of salt (Na+ and Mg2+) to the RNA tertiary structure folding free energy. Folding of the RNA tertiary structure often involves intermediates. We focus on the folding transition from an intermediate state to the native state, and compute the electrostatic folding free energy of the RNA. Based on systematic calculations for a variety of RNA molecules, we derive a set of formulas for the electrostatic free energy for tertiary structural folding as a function of the sequence length and compactness of the RNA and the Na+ and Mg2+ concentrations. Extensive comparisons with experimental data suggest that our model and the extracted empirical formulas are quite reliable. PMID:21723828

    Taran-Benshoshan, Marina; Ofer, Naomi; Dalit, Vaizel-Ohayon; Aharoni, Avi; Revhun, Menahem; Nitzan, Yeshayahu; Nasser, Abidelfatah M


    Wastewater disposal may be a source of environmental contamination by Cryptosporidium and Giardia. This study was conducted to evaluate the prevalence of Cryptosporidium oocysts and Giardia cysts in raw and treated wastewater effluents. A prevalence of 100% was demonstrated for Giardia cysts in raw wastewater, at a concentration range of 10 to 12,225 cysts L(-1), whereas the concentration of Cryptosporidium oocysts in raw wastewater was 4 to 125 oocysts L(-1). The removal of Giardia cysts by secondary and tertiary treatment processes was greater than those observed for Cryptosporidium oocysts and turbidity. Cryptosporidium and Giardia were present in 68.5% and 76% of the tertiary effluent samples, respectively, at an average concentration of 0.93 cysts L(-1) and 9.94 oocysts L(-1). A higher detection limit of Cryptosporidium oocysts in wastewater was observed for nested PCR as compared to immune fluorescent assay (IFA). C. hominis was found to be the dominant genotype in wastewater effluents followed by C. parvum and C. andersoni or C. muris. Giardia was more prevalent than Cryptosporidium in the studied community and treatment processes were more efficient for the removal of Giardia than Cryptosporidium. Zoonotic genotypes of Cryptosporidium were also present in the human community. To assess the public health significance of Cryptosporidium oocysts present in tertiary effluent, viability (infectivity) needs to be assessed.

  15. Mudflow utilization for construction materials of tertiary irrigation canal lining (United States)

    Azis, Subandiyah; Kustamar


    Mudflow in Siring Village, Sidoarjo Regency, Indonesia, has been in eruption since May 29, 2006. It still shows irregular large bursts which loaded in a sludge reservoir with capacity of 59 million m3. From 2007 until 2015, there were more than 20 studies which concluded that the mudflow could be used as a mixture of building materials. However, the studies were not detailed and needed further research. This research aims to investigate the use of mudflow as tertiary irrigation canal lining material. This research comes with several laboratory tests to obtain a mixture that is solid and water-resistant. The methods that were used are descriptive methods as follows: 1). Sampling of mudflow, to be analyzed in Material Testing Laboratory. 2). Sampling of soil at research site, to be analyzed in Soil Mechanics Laboratory 3). Mixing of materials which are consist of mudflow and other materials and doing strength test in the laboratory. 4). Installation of tertiary irrigation canal lining using materials that have been tested. 5). Observation of lining's strength inactive soil pressure-bearing and its impermeability. It is expected that the results of this research will be applied extensively throughout the tertiary irrigation canals, so mudflow can be utilized as raw materials that are environmentally friendly, which are able to help preserving the environment, also to reduce the removal of sand / rock in the river, which has been used for lining materials, that benefits in preventing damage to the river ecosystem.

  16. Tertiary Normal Faulting in the Canyon Range, Eastern Sevier Desert. (United States)

    Wills; Anders


    The contact between pre-Mesozoic and Tertiary rocks in the western Canyon Range, west-central Utah, has been interpreted as a large, low-angle normal fault that marks the breakaway zone of the hypothesized, basin-forming Sevier Desert detachment. Recent fieldwork suggests that the contact may in fact be depositional along much or all of its length. Deformational fabric in the supposed footwall likely traces to the Mesozoic Sevier orogeny rather than to Tertiary detachment faulting. Kinematic indicators at the range front are not generally consistent with low-angle normal-fault motion; instead, well-exposed high-angle faults are the dominant range-bounding structures. The Tertiary conglomerates of the western Canyon Range foothills, previously viewed as an evolving syntectonic deposit related to detachment faulting, are here reinterpreted as three distinct units that reflect different periods and tectonic settings. The pattern in these conglomerates, and in fault-offset gravity-slide deposits that mantle the western foothills, is consistent with block faulting and rotation along several generations of high-angle structures. Local seismic-reflection data lend qualitative support to this interpretation, and underscore the need to consider alternative working hypotheses for evolution of the Sevier Desert basin.

  17. Pediatric Admissions After Dental Care Under General Anesthesia: A Retrospective Study at a Tertiary Care Center. (United States)

    Lucy, Anna L; Gandhi, Roopa P; Gross, Lilyana; McNair, Bryan


    The purpose of this study was to identify factors associated with planned and unplanned pediatric hospital admissions following dental treatment under general anesthesia (DGA) in a tertiary care center. Dental and medical records of 100 subjects one to 20 years of age, with a known history of admission after DGA, were reviewed retrospectively for patient-, procedure-, and anesthesia-related factors as well as adverse events following DGA. During the review period (December 3, 2011 to June 30, 2015), 10,371 subjects underwent DGA, of which 100 subjects (less than one percent) required admission. A significant association was found between postoperative (PO) recovery time and unplanned admissions following DGA (P<0.001). Adverse post-operative events significantly associated with unplanned admissions included emesis (P=0.01) and hypoxia (P<0.001). Patients who were classified as having American Anesthesiology Association (ASA) III status were more frequently admitted following DGA. Adverse events such as emesis and hypoxia were significantly associated with patients with an unplanned admission.

  18. Meiotic behaviour of telo-tertiary compensating trisomics of rye: evaluation for use in hybrid varieties. (United States)

    de Vries, J N; Sybenga, J


    Meiosis of four telocentric-tertiary compensating trisomics of rye (Secale cereale L.) was studied with the purpose of evaluating their suitability for use in maintaining genic male-sterile lines applied in hybrid varieties. They had been constructed from four different reciprocal translocations and three different telocentrics. In one trisomic a slight, but significant tendency was demonstrated for preferential pairing of the two normal chromosomes associated with the compensating complex. This promotes the desired segregation into one normal and one compensating karyotype. In all trisomies, however, too high a frequency of failure of chiasma formation in a critical segment of the complex was evident. This is correlated with the ease of recovery of the trisomics, but results in undesired segregational products. Interstitial chiasmata leading to the formation of branched configurations were also present, more in some trisomics than in others. These also result in undesired segregations. The behaviour at meiosis was so closely correlated with the length of the chromosome segments involved that a prediction of the most favourable combination of telocentric and translocation can be made. The telocentric should be large, the corresponding translocated segment large and the interstitial segment small. The non-translocated arm of the translocated chromosome should be large and the second translocated segment small. The combinations of translocations and telocentrics had not been selected for these criteria and did not meet the requirements for practical application.

  1. Topological constraints are major determinants of tRNA tertiary structure and dynamics and provide basis for tertiary folding cooperativity. (United States)

    Mustoe, Anthony M; Brooks, Charles L; Al-Hashimi, Hashim M


    Recent studies have shown that basic steric and connectivity constraints encoded at the secondary structure level are key determinants of 3D structure and dynamics in simple two-way RNA junctions. However, the role of these topological constraints in higher order RNA junctions remains poorly understood. Here, we use a specialized coarse-grained molecular dynamics model to directly probe the thermodynamic contributions of topological constraints in defining the 3D architecture and dynamics of transfer RNA (tRNA). Topological constraints alone restrict tRNA's allowed conformational space by over an order of magnitude and strongly discriminate against formation of non-native tertiary contacts, providing a sequence independent source of folding specificity. Topological constraints also give rise to long-range correlations between the relative orientation of tRNA's helices, which in turn provides a mechanism for encoding thermodynamic cooperativity between distinct tertiary interactions. These aspects of topological constraints make it such that only several tertiary interactions are needed to confine tRNA to its native global structure and specify functionally important 3D dynamics. We further show that topological constraints are conserved across tRNA's different naturally occurring secondary structures. Taken together, our results emphasize the central role of secondary-structure-encoded topological constraints in defining RNA 3D structure, dynamics and folding. © The Author(s) 2014.

    The recovery of uranium from the acidic aqueous metal waste solutions resulting from the bismuth phosphate carrier precipitation of plutonium from solutions of neutron irradiated uranium is described. The waste solutions consist of phosphoric acid, sulfuric acid, and uranium as a uranyl salt, together with salts of the fission products normally associated with neutron irradiated uranium. Generally, the process of the invention involves the partial neutralization of the waste solution with sodium hydroxide, followed by conversion of the solution to a pH 11 by mixing therewith sufficient sodium carbonate. The resultant carbonate-complexed waste is contacted with a titanated silica gel and the adsorbent separated from the aqueous medium. The aqueous solution is then mixed with sufficient acetic acid to bring the pH of the aqueous medium to between 4 and 5, whereby sodium uranyl acetate is precipitated. The precipitate is dissolved in nitric acid and the resulting solution preferably provided with salting out agents. Uranyl nitrate is recovered from the solution by extraction with an ether such as diethyl ether.

  3. Immune recovery vitritis

    Directory of Open Access Journals (Sweden)

    Dujić Mirjana


    Full Text Available Introduction Immune recovery vitritis (IRV is symptomatic vitritis of > 1+ severity associated with inactive cytomegalovirus (CMV retinitis. It is an opportunistic infection of the eye, in the patients who suffer from AIDS, and is treated with a highly active antiretroviral therapy (HAART. As a result of this therapy, there is an immune reconstitution in the body and inflammation of the vitreous body. Objective The aim of the study was to show the incidence of IRV in patients treated with HAART. Method A retrospective study was conducted in patients who suffered from CMV retinitis. Twenty-one were treated with HAART and had the diagnosis of CMV retinitis, as well. All of them were examined by the same ophthalmologist who peformed slit lamp examination with mydriasis and indirect ophthalmoscopy. Results Nine of 21 patients developed IRV as a complication of HAART, two had cystoid macular edema (CMO. Conclusion CMV retinitis develops when the number of CD4+ T lymphocytes drops below 50/mm3. This results in necrotic retinitis which, if untreated, leads to complete loss of vision. With the introduction of HAART, we learned that the reconstitution of immune status was achieved as well as life expectancy, but there was a dramatic decline in the opportunistic infection, including CMV retinitis, as well. With the immune reconstitution, the inflammation develops in the eye, known as IRV. Sometimes, it is necessary to treat this condition, but in the case of our patients, the inflammation was mild, and no treatment was necessary.

  4. LHC Report: Rocky Recovery

    CERN Document Server

    Mike Lamont for the LHC Team


    The last technical stop finished on Friday 8 July, but the machine returned to its pre-stop performance level over a week later.   Efficiency of LHC fills between 16 July and 20 July, 2011. The cryogenics team had the entire ring cold by Saturday morning and the usual post-technical stop tests with circulating beams started soon after. Unfortunately, they were interrupted by a major perturbation to CERN’s electrical network caused by an impressive thunderstorm that swept over the Pays de Gex. There were major knock-on effects, including the loss of cooling to the cryogenics and an inevitable recovery period once normal service had been re-established. The beams were circulating again by Tuesday afternoon and the post-technical stop checks continued, beefed up with further tests to address a number of issues related to the power cut.  Before the stop, the LHC had managed to get 1380 bunches per beam into collisions and the plan was to ramp back up relatively quickly to this leve...

  5. Recovery from cannabis use disorders: Abstinence versus moderation and treatment-assisted recovery versus natural recovery. (United States)

    Stea, Jonathan N; Yakovenko, Igor; Hodgins, David C


    The present study of recovery from cannabis use disorders was undertaken with 2 primary objectives that address gaps in the literature. The first objective was to provide an exploratory portrait of the recovery process from cannabis use disorders, comparing individuals who recovered naturally with those who were involved in treatment. The second objective was to explore systematically the similarities and differences between abstinence and moderation recoveries. Adults who have recovered from a cannabis use disorder were recruited in the community (N = 119). The abstinence and treatment-assisted participants exhibited higher levels of lifetime cannabis problem severity than the moderation and natural recovery participants, respectively. As well, cognitive factors were identified as the most useful strategies for recovery (e.g., thinking about benefits and negative consequences of cannabis), followed by behavioral factors (e.g., avoidance of triggers for use and high-risk situations). Findings lend further support to the effectiveness of cognitive, motivational, and behavioral strategies as helpful actions and maintenance factors involved in the recovery process. The findings also generally support the idea that cannabis use disorders lie on a continuum of problem severity, with moderation and natural recoveries more likely to occur at the lower end of the continuum and abstinence and treatment-assisted recoveries more likely to occur at the upper end.

  6. Course of Recovery from Alcoholism (United States)

    Venner, Kamilla L.; Matzger, Helen; Forcehimes, Alyssa A.; Moos, Rudolf H.; Feldstein, Sarah W.; Willenbring, Mark L.; Weisner, Constance


    This article represents the proceedings of a symposium at the 2005 Research Society on Alcoholism meeting in Santa Barbara, California, organized and chaired by Kamilla L. Venner. This symposium integrated current empirical research on the course of recovery from alcoholism from multiple perspectives, an aim that is consistent with NIAAA's new focus on the process of recovery. The presentations and presenters were as follows: (1) The Role of Community Services and Informal Support on 7-Year Drinking Outcomes in Treated and Untreated Drinkers, by Helen Matzger; (2) The Sequence of Recovery Events in a Native American Sample, by Kamilla L. Venner; (3) Transformational Change in Recovery, by Alyssa A. Forcehimes; (4) Social Settings and Substance Use: Contextual Factors in Recovery, by Rudolf H. Moos; and (5) A Broader View of Change in Drinking Behavior, by discussant Mark L. Willenbring. A theme connecting the presentations was that treatment is but one discrete aspect to recovery and that sustained recovery is often influenced by an individual interaction with others within a social context. Collectively, presentations underscored the need to think more broadly about factors contributing to the remission of alcohol dependence. PMID:16737468

  7. Global patterns of drought recovery (United States)

    Drought, a recurring phenomenon with major impacts on both human and natural systems, is the most widespread climatic extreme that negatively affects the land carbon sink. Although twentieth-century trends in drought regimes are ambiguous, across many regions more frequent and severe droughts are expected in the twenty-first century. Recovery time—how long an ecosystem requires to revert to its pre-drought functional state—is a critical metric of drought impact. Yet the factors influencing drought recovery and its spatiotemporal patterns at the global scale are largely unknown. Here we analyse three independent datasets of gross primary productivity and show that, across diverse ecosystems, drought recovery times are strongly associated with climate and carbon cycle dynamics, with biodiversity and CO2 fertilization as secondary factors. Our analysis also provides two key insights into the spatiotemporal patterns of drought recovery time: first, that recovery is longest in the tropics and high northern latitudes (both vulnerable areas of Earth’s climate system) and second, that drought impacts (assessed using the area of ecosystems actively recovering and time to recovery) have increased over the twentieth century. If droughts become more frequent, as expected, the time between droughts may become shorter than drought recovery time, leading to permanently damaged ecosystems and widespread degradation of the land carbon sink.

It is noted that a safe return to earth does not guarantee a successful recovery. The focus of this presentation will be a discussion of the ground operation assets involved in a successful recovery. The author's experience in land and water-based recovery of crewed vehicles and flight hardware at Kennedy Space Center (KSC), Edwards Air Force Base, international landing sites, and the Atlantic Ocean provides for some unique insight into this topic. He has participated in many aspects of Space Shuttle landing and recovery operations including activation of Transatlantic Abort Landing (TAL) sites and Emergency Landing Sites (ELS) as an Operations Test Director, execution of post landing convoy operations as an Orbiter Move Director, Operations Test Director, and Landing and Recovery Director, and recovery of solid rocket boosters, frustum and their parachutes 140 miles offshore in a wide range of sea states as a Retrieval Diver/Engineer. The recovery operations for the Mercury, Gemini, and Apollo were similar from a landing and recovery perspective in th t they all were capsules with limited "flying" capability and had a planned End of Mission (EOM) in an ocean with a descent slowed by parachutes. The general process was to deploy swim teams via helicopters to prepare the capsule for recovery and assist with crew extraction when required. The capsule was then hoisted onto the deck of a naval vessel. This approach required the extensive use and deployment of military assets to support the primary landing zone as well as alternate and contingency locations. The Russian Soyuz capsule also has limited "flying" capability; however, the planned EOM is terrestrial. In addition to use of parachutes to slow the reentry descent, soft-landing rockets on the bottom of the vehicle are employed to cushion the

    Muscle injuries are one of the most common traumas occurring in sports. Despite their clinical importance, there are only a few clinical studies on the treatment of muscle injuries. Lack of clinical studies is most probably attributable to the fact that there is not only a high heterogeneity in the severity of injuries, but also the injuries take place in different muscles, making it very demanding to carry out clinical trials. Accordingly, the current treatment principles of muscle injuries have either been derived from experimental studies or been tested empirically only. Clinically, first aid for muscle injuries follows the RICE (Rest, Ice, Compression and Elevation) principle. The objective of RICE is to stop the injury-induced bleeding into the muscle tissue and thereby minimise the extent of the injury. Clinical examination should be carried out immediately after the injury and 5-7 days after the initial trauma, at which point the severity of the injury can be assessed more reliably. At that time, a more detailed characterisation of the injury can be made using imaging diagnostic modalities (ultrasound or MRI) if desired. The treatment of injured skeletal muscle should be carried out by immediate immobilisation of the injured muscle (clinically, relative immobility/avoidance of muscle contractions). However, the duration of immobilisation should be limited to a period sufficient to produce a scar of sufficient strength to bear the forces induced by remobilisation without re-rupture and the return to activity (mobilisation) should then be started gradually within the limits of pain. Early return to activity is needed to optimise the regeneration of healing muscle and recovery of the flexibility and strength of the injured skeletal muscle to pre-injury levels. The rehabilitation programme should be built around progressive agility and trunk stabilisation exercises, as these exercises seem to yield better outcome for injured skeletal muscle than programmes based

  13. Novel Regenerated Solvent Extraction Processes for the Recovery of Carboxylic Acids or Ammonia from Aqueous Solutions Part II. Recovery of Ammonia from Sour Waters

    Two novel regenerated solvent extraction processes are examined. The first process has the potential to reduce the energy costs inherent in the recovery of low-volatility carboxylic acids from dilute aqueous solutions. The second process has the potential for reducing the energy costs required for separate recovery of ammonia and acid gases (e.g. CO2 and H2S) from industrial sour waters. The recovery of carboxylic acids from dilute aqueous solution can be achieved by extraction with tertiary amines. An approach for regeneration and product recovery from such extracts is to back-extract the carboxylic acid with a water-soluble, volatile tertiary amine, such as trimethylamine. The resulting trimethylammonium carboxylate solution can be concentrated and thermally decomposed, yielding the product acid and the volatile amine for recycle. Experimental work was performed with lactic acid, SUCCiOlC acid, and fumaric acid. Equilibrium data show near-stoichiometric recovery of the carboxylic acids from an organic solution of Alamine 336 into aqueous solutions of trimethylamine. For fumaric and succinic acids, partial evaporation of the aqueous back extract decomposes the carboxylate and yields the acid product in crystalline form. The decomposition of aqueous solutions of trimethylammonium lactates was not carried out to completion, due to the high water solubility of lactic acid and the tendency of the acid to self-associate. The separate recovery of ammonia and acid gases from sour waters can be achieved by combining steam-stripping of the acid gases with simultaneous removal of ammonia by extraction with a liquid cation exchanger. The use of di-2,4,4-trimethylpentyl phosphinic acid as the liquid cation exchanger is explored in this work. Batch extraction experiments were carried out to measure the equilibrium distribution ratio of ammonia between an aqueous buffer solution and an organic solution of the phosphinic acid (0.2N) in Norpar 12.

    This work presents the preliminary results of the studies aiming to develop a hydrometallurgical process to produce uranium and thorium concentrates from thorianite ore from Amapa State, Brazil. This process comprises two major parts: acid leaching and Th/U recovery using solvent extraction strategies. Thorianite ore has a typical composition of 60 - 70% of thorium, 8 - 10% lead and 7 - 10% uranium. Sulfuric acid leaching operational conditions were defined as follows: acid/ore ratio 7.5 t/t, ore size below 65 mesh (Tyler), 2 hours leaching time and temperature of 100 deg C. Leaching tests results showed that uranium and thorium recovery exceeded 95%, whereas 97% of lead ore content remained in the solid form. Uranium and thorium simultaneous solvent extraction is necessary due to high sulfate concentration in the liquor obtained from leaching, so the Primene JM-T primary anime was used for this extraction step. Aqueous raffinate from extraction containing sulfuric acid was recycled to the leaching step, reducing acid uptake around 60%, to achieve a net sulfuric acid consumption of 3 t/t of ore. Uranium and thorium simultaneous stripping was performed using sodium carbonate solution. In the aqueous stripped it was added sulfuric acid at pH 1.5, followed by a second solvent extraction step using the tertiary amine Alamine 336. The following stripping step was done with a solution of sodium chloride, resulting in a final solution of 23 g L-1 uranium. (author)

    Current technology recovers only one-third to one-half of the oil that is originally present in an oil reservoir. Entrapment of petroleum hydrocarbons by capillary forces is a major factor that limits oil recovery (1, 3, 4). Hydrocarbon displacement can occur if interfacial tension (IFT) between the hydrocarbon and aqueous phases is reduced by several orders of magnitude. Microbially-produced biosurfactants may be an economical method to recover residual hydrocarbons since they are effective at low concentrations. Previously, we showed that substantial mobilization of residual hydrocarbon from a model porous system occurs at biosurfactant concentrations made naturally by B. mojavensis strain JF-1 if a polymer and 2,3-butanediol were present (2). In this report, we include data on oil recovery from Berea sandstone experiments along with our previous data from sand pack columns in order to relate biosurfactant concentration to the fraction of oil recovered. We also investigate the effect that the JF-2 biosurfactant has on interfacial tension (IFT). The presence of a co-surfactant, 2,3-butanediol, was shown to improve oil recoveries possibly by changing the optimal salinity concentration of the formulation. The JF-2 biosurfactant lowered IFT by nearly 2 orders of magnitude compared to typical values of 28-29 mN/m. Increasing the salinity increased the IFT with or without 2,3-butanediol present. The lowest interfacial tension observed was 0.1 mN/m. Tertiary oil recovery experiments showed that biosurfactant solutions with concentrations ranging from 10 to 60 mg/l in the presence of 0.1 mM 2,3-butanediol and 1 g/l of partially hydrolyzed polyacrylamide (PHPA) recovered 10-40% of the residual oil present in Berea sandstone cores. When PHPA was used alone, about 10% of the residual oil was recovered. Thus, about 10% of the residual oil recovered in these experiments was due to the increase in viscosity of the displacing fluid. Little or no oil was recovered at

  16. Tertiary siRNAs mediate paramutation in C. elegans. (United States)

    Sapetschnig, Alexandra; Sarkies, Peter; Lehrbach, Nicolas J; Miska, Eric A


    In the nematode Caenorhabditis elegans, different small RNA-dependent gene silencing mechanisms act in the germline to initiate transgenerational gene silencing. Piwi-interacting RNAs (piRNAs) can initiate transposon and gene silencing by acting upstream of endogenous short interfering RNAs (siRNAs), which engage a nuclear RNA interference (RNAi) pathway to trigger transcriptional gene silencing. Once gene silencing has been established, it can be stably maintained over multiple generations without the requirement of the initial trigger and is also referred to as RNAe or paramutation. This heritable silencing depends on the integrity of the nuclear RNAi pathway. However, the exact mechanism by which silencing is maintained across generations is not understood. Here we demonstrate that silencing of piRNA targets involves the production of two distinct classes of small RNAs with different genetic requirements. The first class, secondary siRNAs, are localized close to the direct target site for piRNAs. Nuclear import of the secondary siRNAs by the Argonaute HRDE-1 leads to the production of a distinct class of small RNAs that map throughout the transcript, which we term tertiary siRNAs. Both classes of small RNAs are necessary for full repression of the target gene and can be maintained independently of the initial piRNA trigger. Consistently, we observed a form of paramutation associated with tertiary siRNAs. Once paramutated, a tertiary siRNA generating allele confers dominant silencing in the progeny regardless of its own transmission, suggesting germline-transmitted siRNAs are sufficient for multigenerational silencing. This work uncovers a multi-step siRNA amplification pathway that promotes germline integrity via epigenetic silencing of endogenous and invading genetic elements. In addition, the same pathway can be engaged in environmentally induced heritable gene silencing and could therefore promote the inheritance of acquired traits.

    Commercial purity aluminium (99.5%) has been cold rolled to a true strain of 5.5 (99.6% reduction in thickness). The material is very strong but low temperature recovery may be a limiting factor. This has been investigated by isothermal annealing treatments in the temperature range 5–100C. Hardness...... tests, microstructural investigations by electron backscattered diffraction (EBSD) and transmission electron microscopy (TEM) were carried out to identify and characterise possible recovery mechanisms. Annihilation of zigzagged dislocations, positioned between deformationinduced lamellar boundaries...... of medium-to-high angles, and annihilation of dislocations in boundaries were found to be important recovery mechanisms, whereas other mechanisms, such as triple junction motion, subgrain coalescence, and boundary migration, were less important or negligible.

  5. Uncovering Recovery: The Resistible Rise of Recovery and Resilience

    Directory of Open Access Journals (Sweden)

    David Harper


    Full Text Available Discourses of recovery and resilience have risen to positions of dominance in the mental health field. Models of recovery and resilience enjoy purchase, in both policy and practice, across a range of settings from self-described psychiatric survivors through to mental health charities through to statutory mental health service providers. Despite this ubiquity, there is confusion about what recovery means. In this article we problematize notions of recovery and resilience, and consider what, if anything, should be recovered from these concepts. We focus on three key issues, i individualization, ii the persistence of a deficit model, and iii collective approaches to recovery. Through documentary analysis we consider these issues across third sector organizations, and public and mental health policy. Firstly, definitional debates about recovery reflect wider ideological debates about the nature of mental health. The vagueness of these concepts and implicit assumptions inherent in dominant recovery and resilience discourses render them problematic because they individualize what are social problems. Secondly, these discourses, despite being seen as inherently liberatory are conceptually dependent on a notion of deficit in that talk of “positives” and “strengths” requires the existence of “negatives” and “weaknesses” for these concepts to make sense.  We argue that this does little to substantially transform dominant understandings of psychological distress. Thirdly, these issues combine to impact upon the progressive potential of recovery. It comes to be seen as an individualistic experiential narrative accompaniment to medical understandings where the structural causes of distress are obscured. This in turn impacts upon the potential for recovery to be used to explore more collective, political aspects of emotional distress. Drawing on the work of Fraser, we use this critique to characterize “recovery” as a “struggle for

  7. From Ramachandran Maps to Tertiary Structures of Proteins. (United States)

    DasGupta, Debarati; Kaushik, Rahul; Jayaram, B


    Sequence to structure of proteins is an unsolved problem. A possible coarse grained resolution to this entails specification of all the torsional (Φ, Ψ) angles along the backbone of the polypeptide chain. The Ramachandran map quite elegantly depicts the allowed conformational (Φ, Ψ) space of proteins which is still very large for the purposes of accurate structure generation. We have divided the allowed (Φ, Ψ) space in Ramachandran maps into 27 distinct conformations sufficient to regenerate a structure to within 5 Å from the native, at least for small proteins, thus reducing the structure prediction problem to a specification of an alphanumeric string, i.e., the amino acid sequence together with one of the 27 conformations preferred by each amino acid residue. This still theoretically results in 27(n) conformations for a protein comprising "n" amino acids. We then investigated the spatial correlations at the two-residue (dipeptide) and three-residue (tripeptide) levels in what may be described as higher order Ramachandran maps, with the premise that the allowed conformational space starts to shrink as we introduce neighborhood effects. We found, for instance, for a tripeptide which potentially can exist in any of the 27(3) "allowed" conformations, three-fourths of these conformations are redundant to the 95% confidence level, suggesting sequence context dependent preferred conformations. We then created a look-up table of preferred conformations at the tripeptide level and correlated them with energetically favorable conformations. We found in particular that Boltzmann probabilities calculated from van der Waals energies for each conformation of tripeptides correlate well with the observed populations in the structural database (the average correlation coefficient is ∼0.8). An alpha-numeric string and hence the tertiary structure can be generated for any sequence from the look-up table within minutes on a single processor and to a higher level of accuracy

[Dr. Fechter GmbH, Umweltlabor und Ingenieurbuero, Berlin (Germany); Rotard, W. [Technische Univ. Berlin (Germany). Inst. fuer Technischen Umweltschutz, Abt. Klimachemie


    Since 1999 dioxin of possibly natural origin has repeatedly been found in kaolinitic clays of different countries. Until today it is not generally agreed how the dioxin was generated. The aim of this study is to determine the relationship between the dioxin content and the mineralogical composition of clays as well as the distribution of dioxin in different grain size fractions and its behaviour within a profile of Tertiary kaolinitic clays from Germany. The study may provide a hypothesis of dioxin formation, based on the genesis of the clays.

  9. Loop Entropy Assists Tertiary Order: Loopy Stabilization of Stacking Motifs

    Directory of Open Access Journals (Sweden)

    Daniel P. Aalberts


    Full Text Available The free energy of an RNA fold is a combination of favorable base pairing and stacking interactions competing with entropic costs of forming loops. Here we show how loop entropy, surprisingly, can promote tertiary order. A general formula for the free energy of forming multibranch and other RNA loops is derived with a polymer-physics based theory. We also derive a formula for the free energy of coaxial stacking in the context of a loop. Simulations support the analytic formulas. The effects of stacking of unpaired bases are also studied with simulations.

  11. Prognostic value of olfactory bulb volume measurement for recovery in postinfectious and posttraumatic olfactory loss. (United States)

    Rombaux, Philippe; Huart, Caroline; Deggouj, Naima; Duprez, Thierry; Hummel, Thomas


    Several prognostic factors influencing the recovery from olfactory dysfunction have been described. The aim of this study was to investigate whether olfactory bulb volume could be used as a new predictor of olfactory recovery in postinfectious and posttraumatic olfactory loss. Cohort study; Level of evidence, 4. Setting Tertiary university clinic, department of otolaryngology. A cohort of 60 patients with postinfectious (n = 28) and posttraumatic olfactory loss (n = 32) was investigated. Assessment of olfactory function was performed using orthonasal (Sniffin' Sticks test) and retronasal psychophysical olfactory tests, at the time of the diagnosis (t1) and 15 months later (t2). All patients were examined on 3 tesla magnetic resonance imaging, and the olfactory bulbs volume was assessed using planimetric contouring at the time of the diagnosis (t1). Recovery rate was 25% in patients with posttraumatic olfactory loss and 36% in patients with postinfectious olfactory loss. There was a correlation between both orthonasal and retronasal olfactory testing and the initial measurement of the total olfactory bulb volume. In addition, we observed a significant correlation between changes in olfactory functions and initial measurement of the total olfactory bulb volume, with larger volumes relating to higher improvement of olfactory function. Finally, we found that none of the patients with a total olfactory bulb volume of 40 mm(3) or less exhibited recovery of olfactory function. Olfactory bulb volume seems to be a predictor of olfactory recovery in patients with postinfectious and posttraumatic olfactory loss.

    Purpose To investigate motor recovery of stroke patients 1 year after rehabilitation. Materials and Methods A cross-sectional study of 192 stroke patients discharged from rehabilitation wards in nine tertiary hospitals was conducted. Motor recovery was assessed using the Brunnstrom motor recovery stages (BMRS), at 6 and 12 months after discharge. Factors related to the BMRS of the hand, arm and leg were analyzed. Results The mean age of patients was 62.2 years (57.3% male). Significantly more patients presented improvement of at least one BMRS of the hand, arm and leg compared with those with decreasing BMRS (p stroke was near maximal at six months. Regarding the factors related to motor recovery, only lengths of stay (LOS) stroke patients had motor improvement of at least one stage of BMRS at one year. Motor recovery after stroke at the end of the first year was associated with shorter LOS during the first admission, higher discharge Barthel index score and absence of complications at discharge.

  17. Laboratory investigation of the factors impact on bubble size, pore blocking and enhanced oil recovery with aqueous Colloidal Gas Aphron. (United States)

    Shi, Shenglong; Wang, Yefei; Li, Zhongpeng; Chen, Qingguo; Zhao, Zenghao

    Colloidal Gas Aphron as a mobility control in enhanced oil recovery is becoming attractive; it is also designed to block porous media with micro-bubbles. In this paper, the effects of surfactant concentration, polymer concentration, temperature and salinity on the bubble size of the Colloidal Gas Aphron were studied. Effects of injection rates, Colloidal Gas Aphron fluid composition, heterogeneity of reservoir on the resistance to the flow of Colloidal Gas Aphron fluid through porous media were investigated. Effects of Colloidal Gas Aphron fluid composition and temperature on residual oil recovery were also studied. The results showed that bubble growth rate decreased with increasing surfactant concentration, polymer concentration, and decreasing temperature, while it decreased and then increased slightly with increasing salinity. The obvious increase of injection pressure was observed as more Colloidal Gas Aphron fluid was injected, indicating that Colloidal Gas Aphron could block the pore media effectively. The effectiveness of the best blend obtained through homogeneous sandpack flood tests was modestly improved in the heterogeneous sandpack. The tertiary oil recovery increased 26.8 % by Colloidal Gas Aphron fluid as compared to 20.3 % by XG solution when chemical solution of 1 PV was injected into the sandpack. The maximum injected pressure of Colloidal Gas Aphron fluid was about three times that of the XG solution. As the temperature increased, the Colloidal Gas Aphron fluid became less stable; the maximum injection pressure and tertiary oil recovery of Colloidal Gas Aphron fluid decreased.

    Sale, T. [CH2M Hill, Denver, CO (United States); Pitts, M.; Wyatt, K. [Surtek, Inc., Golden, CO (United States)] [and others


    Chemically enhanced recovery is a promising alternative to current technologies for management of subsurface releases of organic liquids. Through the inclusion of surfactants, solvents, polymers, and/or alkaline agents to a waterflood, the transport of targeted organic compounds can be increased and rates of recovery enhanced. By far, the vast majority of work done in the field of chemically enhanced recovery has been at a laboratory scale. The following text focuses on chemically enhanced recovery from a field application perspective with emphasis given to chlorinated solvents in a low permeability setting. While chlorinated solvents are emphasized, issues discussed are also relevant to organic liquids less dense than water such as petroleum products. Topics reviewed include: (1) Description of technology; (2) General technology considerations; (3) Low permeability media considerations; (4) Cost and reliability considerations; (5) Commercial availability; and (6) Case histories. Through this paper an appreciation is developed of both the potential and limitations of chemically enhanced recovery. Excluded from the scope of this paper is the in situ destruction of organic compounds through processes such as chemical or biological oxidation, chemically enhanced recovery of inorganic compounds, and ex situ soil treatment processes. 11 refs., 2 figs., 1 tab.

  19. Global patterns of drought recovery

L.; Michalak, Anna M.; Fisher, Joshua B.; Biondi, Franco; Koch, George; Litvak, Marcy; Ogle, Kiona; Shaw, John D.; Wolf, Adam; Huntzinger, Deborah N.; Schaefer, Kevin; Cook, Robert; Wei, Yaxing; Fang, Yuanyuan; Hayes, Daniel; Huang, Maoyi; Jain, Atul; Tian, Hanqin


    Drought is a recurring multi-factor phenomenon with major impacts on natural and human systems1-3. Drought is especially important for land carbon sink variability, influencing climate regulation of the terrestrial biosphere4. While 20th Century trends in drought regime are ambiguous, “more extreme extremes” as well as more frequent and severe droughts3,7 are expected in the 21st Century. Recovery time, the length of time an ecosystem requires to revert to its pre-drought functional state, is a critical metric of drought impact. Yet the spatiotemporal patterning and controls of drought recovery are largely unknown. Here we use three distinct global datasets of gross primary productivity to show that across diverse terrestrial ecosystems drought recovery times are driven by biological productivity and biodiversity, with drought length and severity of secondary importance. Recovery time, especially for extreme droughts, and the areal extent of ecosystems in recovery from drought generally increase over the 20th Century, supporting an increase globally in drought impact8. Our results indicate that if future Anthropocene droughts become more widespread as expected, that droughts will become more frequent relative to recovery time. This increases the risk of entering a new regime where vegetation never recovers to its original state and widespread degradation of the land carbon sink ensues.

  20. Developing a Regional Recovery Framework

    Lesperance, Ann M.; Olson, Jarrod; Stein, Steven L.; Clark, Rebecca; Kelly, Heather; Sheline, Jim; Tietje, Grant; Williamson, Mark; Woodcock, Jody


    Abstract A biological attack would present an unprecedented challenge for local, state, and federal agencies; the military; the private sector; and individuals on many fronts ranging from vaccination and treatment to prioritization of cleanup actions to waste disposal. To prepare the Seattle region to recover from a biological attack, the Seattle Urban Area Security Initiative (UASI) partners collaborated with military and federal agencies to develop a Regional Recovery Framework for a Biological Attack in the Seattle Urban Area. The goal was to reduce the time and resources required to recover and restore wide urban areas, military installations, and other critical infrastructure following a biological incident by providing a coordinated systems approach. Based on discussions in small workshops, tabletop exercises, and interviews with emergency response agency staff, the partners identified concepts of operation for various areas to address critical issues the region will face as recovery progresses. Key to this recovery is the recovery of the economy. Although the Framework is specific to a catastrophic, wide-area biological attack using anthrax, it was designed to be flexible and scalable so it could also serve as the recovery framework for an all-hazards approach. The Framework also served to coalesce policy questions that must be addressed for long-term recovery. These questions cover such areas as safety and health, security, financial management, waste management, legal issues, and economic development.

  1. Total Value of Phosphorus Recovery. (United States)

    Mayer, Brooke K; Baker, Lawrence A; Boyer, Treavor H; Drechsel, Pay; Gifford, Mac; Hanjra, Munir A; Parameswaran, Prathap; Stoltzfus, Jared; Westerhoff, Paul; Rittmann, Bruce E


    Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements in P-use efficiency. While this motivation is increasingly being recognized, little P recovery is practiced today, as recovered P generally cannot compete with the relatively low cost of mined P. Therefore, P is often captured to prevent its release into the environment without beneficial recovery and reuse. However, additional incentives for P recovery emerge when accounting for the total value of P recovery. This article provides a comprehensive overview of the range of benefits of recovering P from waste streams, i.e., the total value of recovering P. This approach accounts for P products, as well as other assets that are associated with P and can be recovered in parallel, such as energy, nitrogen, metals and minerals, and water. Additionally, P recovery provides valuable services to society and the environment by protecting and improving environmental quality, enhancing efficiency of waste treatment facilities, and improving food security and social equity. The needs to make P recovery a reality are also discussed, including business models, bottlenecks, and policy and education strategies.

  2. Loop transfer recovery for general observer architecture

    Niemann, Hans Henrik; Søgaard-Andersen, Per; Stoustrup, Jakob


    A general and concise formulation is given of the loop transfer recovery (LTR) design problem based on recovery errors. Three types of recovery errors are treated: open loop recovery, sensitivity recovery and input-output recovery errors. The three corresponding versions of the asymptotic recovery...... recovery cases. This general recovery formulation covers all known observer based compensator types as special cases. The conditions given in this setting are effectively the aim of all known LTR design methods. The recovery formulation is interpreted in terms of a modelmatching problem as well, which...... is examined by means of the Q-parametrization. It is shown how the general controller obtained by the Q-parametrization can be written as a Luenberger observer based controller. In all cases, n controller states suffice to achieve recovery. The compensators are characterized for errors both on the input...

  3. Alkaline assisted thermal oil recovery: Kinetic and displacement studies

    Energy Technology Data Exchange (ETDEWEB)

    Saneie, S.; Yortsos, Y.C.


    This report deals with two major issues of chemical assisted flooding - the interaction of caustic, one of the proposed additives to steam flood, with the reservoir rock, and the displacement of oil by a chemical flood at elevated temperatures. A mathematical model simulating the kinetics of silica dissolution and hydroxyl ion consumption in a typical alkaline flooding environment is first developed. The model is based on the premise that dissolution occurs via hydrolysis of active sites through the formation of an intermediate complex, which is in equilibrium with the silicic acid in solution. Both static (batch) and dynamic (core flood) processes are simulated to examine the sensitivity of caustic consumption and silica dissolution to process parameters, and to determine rates of propagation of pH values. The model presented provides a quantitative description of the quartz-alkali interaction in terms of pH, salinity, ion exchange properties, temperature and contact time, which are of significant importance in the design of soluble silicate flooding processes. The modeling of an adiabatic hot waterflood assisted by the simultaneous injection of a chemical additive is next presented. The model is also applicable to the hot alkaline flooding under conditions of negligible adsorption of the generated anionic surfactant and of hydroxide adsorption being Langmuirian. The theory of generalized simple waves (coherence ) is used to develop solutions for the temperature, concentration, and oil saturation profiles, as well as the oil recovery curves. It is shown that, for Langmuir adsorption kinetics, the chemical resides in the heated region of the reservoir if its injection concentration is below a critical value, and in the unheated region if its concentration exceeds this critical value. Results for a chemical slug injection in a tertiary recovery process indicate recovery performance is maximized when chemical resides in the heated region of the reservior.

  4. Citizenship and recovery: two intertwined concepts for civic-recovery. (United States)

    Pelletier, Jean-François; Corbière, Marc; Lecomte, Tania; Briand, Catherine; Corrigan, Patrick; Davidson, Larry; Rowe, Michael


    Validation of the psychometric properties of a new measure of citizenship was required for a research project in the province of Quebec, Canada. This study was meant to study the interplay between recovery- and citizenship-oriented supportive employment. As recovery and citizenship were expected to be two related concepts, convergent validity between the Citizenship Measure (CM) and the Recovery Assessment Scale (RAS) was tested. Study objectives were to: 1) conduct exploratory factor analyses on the CM and confirmatory factor analysis on the RAS tools (construct validity), 2) calculate Cronbach's alphas for each dimension emerging from objective 1 (reliability), and 3) calculate correlations between all dimensions from both tools (convergent validity). Data were collected from 174 individuals with serious mental illness, working in social firms. Serious mental illnesses include major depression, schizophrenia, bipolar disorder, obsessive compulsive disorder, panic disorder, post traumatic stress disorder and borderline personality disorder. Five factors emerged from the exploratory factor analysis of the CM, with good reliability. Confirmatory factor analyses showed that the short and the long versions of the RAS present satisfactory results. Finally, the correlation matrix indicated that all dimensions from both tools are significantly correlated, thus confirming their convergent validity. This study confirms the validity and reliability of two tools, CM and RAS. These tools can be used in combination to assess citizenship and recovery, both of which may be combined in the new concept of civic-recovery.

  5. Halitosis amongst students in tertiary institutions in Lagos state. (United States)

    Arinola, J E; Olukoju, O O


    Halitosis is defined as a noticeable unpleasant odor from the mouth. It is a medico-social problem that affects a significant number of people around the world. Research reveals that nearly 50% of the adult population has halitosis. To determine level of awareness of halitosis and prevalence of the condition amongst students in tertiary institutions as a baseline survey. For this project, 100 students from three tertiary institutions in Lagos state were chosen: University of Lagos, Lagos State University, Ojo campus and Yaba College of Technology. A semi-structured questionnaire and practical testing/diagnostic tool were utilized. Data collected was collated and analyzed using Microsoft Excel 2007 and SPSS statistical software. Most of the respondents were single and Christian. Level of awareness of halitosis was high. Results showed that 15%, 2% and 22% from UNILAG, LASU and YCT respectively said they had halitosis. Using the diagnostic tool, 6%, 8% and 2% respectively were positive for halitosis. There is high level of awareness of halitosis among the respondents. The prevalence of the disorder is low, however, it is recommended that enlightenment campaigns be mounted in schools to improve level of awareness and treatment seeking.

    Kyle, Pippa M; Coghlan, Peter; Matthews, Jeannie; de Ryke, Rex; Reid, Rosemary


    To establish the accuracy of prenatal diagnosis in a tertiary referral fetal medicine unit by comparing those diagnoses made prenatally with diagnoses made at birth until discharge, and with postmortem information from cases that resulted in termination, intrauterine, or neonatal death. All cases seen in the Fetal Medicine Unit between 1 June 2004 and 30 November 2005 were collected prospectively and sorted according to diagnosis. Relevant outcome data for these pregnancies were collected including postmortem information. 681 cases seen which accounted for 1219 visits. 198 were classified prenatally as a major abnormality, 46 cases minor, 56 with raised nuchal translucency, and 381 no abnormality. Outcome details were not available for analysis in two cases. Therefore 679 (99.7%) cases were available (711 out of 713 fetuses). Of the liveborns, 93.6% of the prenatal diagnoses were confirmed, 5.1% were resolved (predominantly soft markers), and 1.3% resulted in an additional major abnormality that had a significant clinical effect. Postmortem examinations were performed on 52% fetal or neonatal deaths with a normal or unknown karyotype. There was one new finding at postmortem that changed the fetal medicine diagnosis significantly. Accuracy of prenatal diagnosis in a tertiary fetal medicine unit is high. Parents and staff need to be aware that not all abnormalities will be detected prenatally, but inaccurate diagnosis is uncommon. Clinical indicators for benchmarking need to be developed.

    Ectopic (or tertiary) lymphoid tissue develops at sites of inflammation or infection in non lymphoid organs and is associated with chronic inflammation. In colon mucosa, small lymphoid aggregates are already present in homeostatic conditions, as part of the gut-associated lymphoid tissue and play an essential role in the immune response to perturbations of the mucosal microenvironment. Despite the recognized role of inflammation in tumor progression, the presence and biological function of lymphoid tissue in cancer has been poorly investigated. We identified aggregates of lymphocytes resembling tertiary lymphoid tissue in human colorectal cancer specimens; intratumor accumulations of lymphocytes display a high degree of compartmentalization, with B and T cells, mature dendritic cells and a network of CD21{sup +} follicular dendritic cells (FDC). We analyzed the adaptation of colon lymphoid tissue in a murine model of colitis-associated cancer (AOM/DSS). B cell follicle formation increases in the context of the chronic inflammation associated to intestinal neoplasia, in this model. A network of lymphatic and haematic vessels surrounding B cell follicles is present and includes high endothelial venules (HEV). Future task is to determine whether lymphoid tissue contributes to the persistence of the tumor-associated inflammatory reaction, rather than represent a functional immune compartment, potentially participating to the anti tumor response.

    Full Text Available For tertiary English as a Foreign Language (EFL students, academic writing is not an easy task. It requires knowledge of the academic writing genres with their particular linguistic features. Moreover, academic writing demands good critical thinking. This research aims to explore the students' academic writing competencies that also focus on critical thinking. The research involved thirty-six first-year tertiary EFL students from a regular class of a private university in Pontianak, West Kalimantan, Indonesia. The source for data collection was the students’ texts. Three texts were selected and the students were categorized into low, medium, and high levels of writing achievement. The text analysis utilized functional grammar rooted in systemic functional linguistics (Emilia, 2014. The analysis shows that the students, regardless of their levels of writing achievement, have little control over the schematic structure and linguistic features of an argumentative writing. The text analysis also shows that the students’ texts have some limitations as regards their critical thinking capacity. Still, a few examples of academic language were detected in the texts. The findings suggest that the lecturer should incorporate explicit teaching and cooperative learning activities to alleviate the students' difficulties and develop their academic writing and critical thinking capacity.

As a means to fill this gap and provide a better understanding the following study using Biggs (1987c Study Process Questionnaire (SPQ, a 42-item self-report survey consisting of ratings on a 5-point scale to questions relating to respondents' study motivations and their usual study patterns was conducted with 355 respondents. Findings were consistent with Hong Kong students and supports studies carried out in other countries by Kemper et al. (1989, Kemper and Gow (1991, Niles (1995, Volet and Renshaw (1996, Ramburuth (2001 and Hua, Williams and Hoi (2007. Despite learning in a “rote” manner during their formative years, students have adapted to deeper learning approaches although there is a still a slight but insignificant bias to surface learning. They desire to achieve and get good marks although strategy is limiting their progress. According to Biggs, this is commonly caused by a language problem.

    Llave, F.M.; Gall, B.L.; French, T.R.; Noll, L.A.; Munden, S.A.


    The results of an evaluation of different mixed surfactant and alkaline-enhanced surfactant systems for enhanced oil recovery are described. Several mixed surfactant systems have been studies to evaluate their oil recovery potential as well as improved adaptability to different ranges of salinity, divalent ion concentrations, and temperature. Several combinations of screening methods were used to help identify potential chemical formulations and determine conditions where particular chemical systems can be applied. The effects of different parameters on the behavior of the overall surfactant system were also studied. Several commercially available surfactants were tested as primary components in the mixtures used in the study. These surfactants were formulated with different secondary as well as tertiary components, including ethoxylated and non-ethoxylated sulfonates and sulfates. Improved salinity and hardness tolerance was achieved for some of these chemical systems. The salinity tolerance of these systems were found to be dependent on the molecular weight, surfactant type, and concentration of the surfactant components.

  16. Clinico-microbiological profile and outcomes of nosocomial sepsis in an Indian tertiary care hospital--a prospective cohort study. (United States)

    Saravu, Kavitha; Prasad, Madhura; Eshwara, Vandana Kalwaje; Mukhopadhyay, Chiranjay


    Nosocomial infections are linked to rising morbidity and mortality worldwide. We sought to investigate the pattern of nosocomial sepsis, device usage, risk factors for mortality and the antimicrobial resistance pattern of the causative organisms in medical intensive care units (ICUs) in an Indian tertiary care hospital. We conducted a single-centre based prospective cohort study in four medical ICUs and patients who developed features of sepsis 48 hours after admission to the ICUs were included. Patients' demographics, indwelling device usage, microbiological culture reports, drug resistance patterns and the outcomes were recorded. The Acute Physiology and Chronic Health Evaluation (APACHE) III score and the relative risk of variables contributing towards non recovery were calculated. Pneumonia (49%) was the commonest nosocomial infection resulting in sepsis, followed by urosepsis (21.8%), bloodstream infection (BSI) (10.3%) and catheter-related bloodstream infection (CRBSI) (5%). Sixty three percent of the Acinetobacter baumannii and 64.4% of the Pseudomonas aeruginosa were multidrug-resistant (MDR). Seventy percent of the Klebsiella pneumoniae were extended spectrum beta-lactamase producers and 7.4% were resistant to carbapenems. Forty three percent of the Staphylococcus aureus were methicillin-resistant S. aureus. Resistance to carbapenems was 35.2% in this study. High APACHE III scores (P = 0.006 by unpaired t-test) and chronic kidney disease (P = 0.023) were significantly associated with non-recovery. A high degree of multidrug resistance was observed among both Gram-positive and -negative organisms in nosocomial sepsis patients. Carbapenem resistance was a common occurrence. Chronic kidney disease and high APACHE III scores were significantly associated with non-recovery. Male gender and sepsis leading to cardiovascular failure were the independent predictors of mortality.

    Full Text Available Abstract Background Vertebral osteomyelitis is a common manifestation of osteomyelitis in adults and associated with considerable morbidity. Limited data exist regarding hematogenous vertebral osteomyelitis. Our objective was to describe the epidemiology and management of hematogenous vertebral osteomyelitis. Methods We performed a 2-year retrospective cohort study of adult patients with hematogenous vertebral osteomyelitis at a tertiary care hospital. Results Seventy patients with hematogenous vertebral osteomyelitis were identified. The mean age was 59.7 years (±15.0 and 38 (54% were male. Common comorbidities included diabetes (43% and renal insufficiency (24%. Predisposing factors in the 30 days prior to admission included bacteremia (19%, skin/soft tissue infection (17%, and having an indwelling catheter (30%. Back pain was the most common symptom (87%. Seven (10% patients presented with paraplegia. Among the 46 (66% patients with a microbiological diagnosis, the most common organisms were methicillin-susceptible S. aureus [15 (33% cases], and methicillin-resistant S. aureus [10 (22%]. Among the 44 (63% patients who had a diagnostic biopsy, open biopsy was more likely to result in pathogen recovery [14 (93% of 15 with open biopsy vs. 14 (48% of 29 with needle biopsy; p = 0.003]. Sixteen (23% patients required surgical intervention for therapeutic purposes during admission. Conclusions This is one of the largest series of hematogenous vertebral osteomyelitis. A microbiological diagnosis was made in only approximately two-thirds of cases. S. aureus was the most common causative organism, of which almost half the isolates were methicillin-resistant.

    Full Text Available INTRODUCTION : Tuberculosis has been a major public health problem. The development and the introduction of antituberculous chemotherapeutic agents in the 1940’s reduced the death rate. Of all the patients with tuberculosis nearly 1 - 3% have involvement of the skeletal system. Vertebral tubercul osis is the most common form of skeletal tuberculosis with a reported incidence of up to 50%. Tuberculosis of the spine (Pott’s disease is the most common and most dangerous from of tuberculosis infection. Modification of surgical techniques and newer che motherapeutic agents has revolutionized the treatment of spinal tuberculosis. AIMS AND OBJECTIVES : To study and analyse the surgical and radiological results of patients who have been operated for dorsal and dorsolumbar caries. MATERIALS AND METHOD : It is a prospective study done in the Department of Neurosurgery, Government General Hospital,Kakinada from July 2014 to July 2015. It is a tertiary care hospital. 50 patients diagnosed with dorsal and dorsolumbar tuberculosis were recruited into the study and w ere managed. RESULTS: 50 patients with dorsal and dorsolumbar tuberculosis, with different symptoms were managed by a combination of surgical techniques and the improvement was assessed by various parameters. CONCLUSION: In this study, it was found that al l patients who underwent surgical decompression of the spinal cord there was improvement in the neurological status. The surgical approach and type of surgery is planned based on how the cord is compressed and the amount of instability. No single surgery w as found superior or inferior to any other and the results remain the same as far as neurological recovery is concerned

  19. The existential way to recovery. (United States)

    Moore, Laurie Jo; Goldner-Vukov, Mila


    This paper explores the essential features of recovery and the need for an existential approach in psychiatry. The biopsychosocial model often fails to sufficiently validate the existential suffering of patients. We review the major principles of recovery and the philosophical and psychiatric principles of existentialism. The ontological or intrinsic existential issues of death, isolation, freedom and meaninglessness are described and their manifestations are explored in clinical syndromes. When ultimate existential concerns are recognised, patients have an opportunity to understand their life on a deeper level that is not defined as a medical disorder but as a part of human existence. Understanding that existential concerns underlie a great deal of human behaviour helps to free patients from the stigma of psychiatric labels. An existential approach is a humanistic way toward recovery.

  8. Recovery times of riparian vegetation (United States)

    Vesipa, Riccardo; Camporeale, Carlo; Ridolfi, Luca


    Riparian vegetation is a key element in a number of processes that determine the eco-geomorphological features of the river landscape. Depending on the river water stage fluctuations, vegetation biomass randomly switches between growth and decay phases, and its biomass exhibits relevant temporal variations. A full understanding of vegetation dynamics is therefore only possible if the hydrological stochastic forcing is considered. In this vein, we focus on the recovery time of vegetation, namely the typical time taken by vegetation to recover a health state starting from a low biomass value (induced, for instance, by an intense flood). The minimalistic stochastic modeling approach is used for describing vegetation dynamics (i.e., the noise-driven alternation of growth and decay phases). The recovery time of biomass is then evaluated according to the theory of the mean first passage time in systems driven by dichotomous noise. The effect of the main hydrological and biological parameters on the vegetation recovery was studied, and the dynamics along the riparian transect was described in details. The effect of climate change and human interventions (e.g., river damming) was also investigated. We found that: (i) the oscillations of the river stage delay the recovery process (up to one order of magnitude, with respect to undisturbed conditions); (ii) hydrological/biological alterations (due to climate change, damming, exotic species invasion) modify the timescales of the recovery. The result provided can be a useful tool for the management of the river. They open the way to the estimation of: (i) the recovery time of vegetation after devastating floods, clear cutting or fires and; (ii) the timescale of the vegetation response to hydrological and biological alterations.

  12. A TLC visualisation reagent for dimethylamphetamine and other abused tertiary amines. (United States)

    Kato, N; Ogamo, A


    Application of citric acid/acetic anhydride reagent (CAR), a colour reagent selective for tertiary amines in solution, improves detection of abused tertiary amino drugs on the TLC plate. The plate is pretreated by a brief immersion in phosphoric acid/acetone solution to suppress colouration. After suppressing, the plate is sprayed with CAR and heated at 100 degrees C, causing tertiary amines to turn red purple within 3 minutes. The sensitivity of this new CAR method is 2.5 to 15-times greater than that of conventional detection with Dragendorff reagent for some of the tertiary amines dimethylamphetamine, methylephedrine, levomepromazine, chlorpromazine, caffeine, theophylline, theobromine and nicotine. This present method provides rapid TLC detection of abused tertiary amino drugs such as phenethylamine, phenothiazine, xanthine derivative, nicotine and narcotics.

  13. Entrepreneurship Education at Tertiary Education Level: Implication to Historical Studies

    Directory of Open Access Journals (Sweden)

    Salahu Mohammed Lawal


    Full Text Available Nigeria is richly endowed with both human and material resources that when well utilized can make her one of the richest and developed nation in the world.  But poor utilization of the resources, corruption and dwindling fortune in her education system made her among the first twenty five poorest nations in the world.  Similarly, report shows that 26% of the employable population remained unemployed.  This called for the need for entrepreneurship education most especially at tertiary level where high level manpower is supposed to be trained.  It is on this premise that the paper attempts to examine entrepreneurship education and its implication to history students and graduates.

  14. Aliphatic and aromatic triterpenoid hydrocarbons in a Tertiary angiospermous lignite

    Energy Technology Data Exchange (ETDEWEB)

    Stout, S.A. (Unocal Science and Technology Division, Brea, CA (USA))


    The hydrocarbon biomarker assemblage of a liptinite-rich, early Tertiary angiospermous lignite has been characterized. The biomarker distribution for the lignite confirms the low maturity and previous paleobotanic interpretations. The aliphatic hydrocarbon fraction consists predominantly of n-alkanes showing a strong odd-carbon predominance, and numerous de-A-triterpenoids and triterpenoids derived from higher plants. Bacterially-derived triterpenoids were represented primarily by homohopanes and hopenes. The aromatic hydrocarbon fraction contains a series of mono-, di-, and triaromatic de-A-triterpenoids and mono-, tri- and tetraaromatic triterpenoids derived from higher plants. The concentration and abundance of monoaromatic triterpenoids containing one to three additional degrees of unsaturation have not been previously observed in a single deposit. As such, a diagenetic scheme for angiosperm-derived triterpenoids is presented which confirms and extends previous hypotheses. 45 refs., 10 figs., 2 tabs.

  15. Cooperative activity and its potential for learning in tertiary education

    Directory of Open Access Journals (Sweden)

    Cirila Peklaj


    Full Text Available A learning situation can be structured in different ways, as an individual, competitive, or cooperative activity. Each of these structures can be used for different purposes and can lead to different learning outcomes. This paper focuses on cooperative activity and its potential for learning in tertiary education. After defining cooperative activity (or, in a broader sense, learning in interaction and introducing the CAMS theoretical framework to analyse cooperative activity, the main discussion focuses on the theoretical reasons for the usefulness of group learning and on the research of effects of cooperative learning on cognitive (metacognitive, affective-motivational and social processes in university students. The key elements that should be established for successful cooperation are also discussed. At the end, a new direction in using cooperative activity in learning—computer supported collaborative learning (CSCL, which emerged with rapid technology development in the last two decades—is presented and discussed.

  16. Medical treatment of primary, secondary, and tertiary hyperparathyroidism

    DEFF Research Database (Denmark)

    Thomsen, Súsanna v.; Vestergaard, Peter


    Hyperparathyroidism is a condition with elevated parathyroid hormone (PTH). The increase may be due to a) primary hyperparathyroidism which is caused by adenoma of one or more parathyroid glands or hyperplasia of all four glands, b) secondary hyperparathyroidism, which may be caused by deficiency...... in vitamin D or uremia, and 3) tertiary hyperparathyroidism, which most often is the result of a long-standing, severe secondary hyperparathyroidism, which has turned autonomous once the cause of the secondary hyperparathyroidism has been removed. Many new treatment options have been introduced in recent...... years. Cinacalcet is calcium sensing receptor agonist, which by stimulating the receptor decreases PTH and calcium levels. It may be used in primary hyperparathyroidism, secondary hyperparathyroidism caused by uremia, which may not be controlled with calcium and activated vitamin D. It may also be used...

  17. Updated Simulation Studies of Damage Limit of LHC Tertiary Collimators

    CERN Document Server

    AUTHOR|(CDS)2085459; Bertarelli, Alessandro; Bruce, Roderik; Carra, Federico; Cerutti, Francesco; Gradassi, Paolo; Lechner, Anton; Redaelli, Stefano; Skordis, Eleftherios


    The tertiary collimators (TCTs) in the LHC, installed in front of the experiments, in standard operation intercept fractions of 10−3 halo particles. However, they risk to be hit by high-intensity primary beams in case of asynchronous beam dump. TCT damage thresholds were initially inferred from results of destructive tests on a TCT jaw, supported by numerical simulations, assuming simplified impact scenarios with one single bunch hitting the jaw with a given impact parameter. In this paper, more realistic failure conditions, including a train of bunches and taking into account the full collimation hierarchy, are used to derive updated damage limits. The results are used to update the margins in the collimation hierarchy and could thus potentially have an influence on the LHC performance.

    Full Text Available Tertiary alkylamines in solution with organic diluents are attractive extractants for the recovery of carboxylic acids from dilute aqueous phases. The aim of this study was to investigate the mechanism for extraction of organic acids from water by a long-chain aliphatic tertiary amine. In order to attain this objective, we studied the liquid-liquid equilibria between the triisooctylamine + 1-octanol + n-heptane system as solvent and an aqueous solution of an individual carboxylic acid such as citric, lactic and malic acids. The experiments showed that the partition coefficient for a particular organic acid depends on the kind of solute, notably when the acid concentration in the aqueous phase is low. A mathematical model, where both chemical association and physical distribution are taken into consideration, is proposed. The model suggests that the various complexes obtained between amine and organic acids contribute to the distribution of the solute between the coexisting phases in equilibrium.

  19. Tertiary alphabet for the observable protein structural universe. (United States)

    Mackenzie, Craig O; Zhou, Jianfu; Grigoryan, Gevorg


    Here, we systematically decompose the known protein structural universe into its basic elements, which we dub tertiary structural motifs (TERMs). A TERM is a compact backbone fragment that captures the secondary, tertiary, and quaternary environments around a given residue, comprising one or more disjoint segments (three on average). We seek the set of universal TERMs that capture all structure in the Protein Data Bank (PDB), finding remarkable degeneracy. Only ∼600 TERMs are sufficient to describe 50% of the PDB at sub-Angstrom resolution. However, more rare geometries also exist, and the overall structural coverage grows logarithmically with the number of TERMs. We go on to show that universal TERMs provide an effective mapping between sequence and structure. We demonstrate that TERM-based statistics alone are sufficient to recapitulate close-to-native sequences given either NMR or X-ray backbones. Furthermore, sequence variability predicted from TERM data agrees closely with evolutionary variation. Finally, locations of TERMs in protein chains can be predicted from sequence alone based on sequence signatures emergent from TERM instances in the PDB. For multisegment motifs, this method identifies spatially adjacent fragments that are not contiguous in sequence-a major bottleneck in structure prediction. Although all TERMs recur in diverse proteins, some appear specialized for certain functions, such as interface formation, metal coordination, or even water binding. Structural biology has benefited greatly from previously observed degeneracies in structure. The decomposition of the known structural universe into a finite set of compact TERMs offers exciting opportunities toward better understanding, design, and prediction of protein structure.

  20. Hospital mortality in cirrhotic patients at a tertiary care center. (United States)

    Zubieta-Rodríguez, R; Gómez-Correa, J; Rodríguez-Amaya, R; Ariza-Mejia, K A; Toloza-Cuta, N A

    Cirrhosis of the liver is known for its high risk of mortality associated with episodes of acute decompensation. There is an even greater risk in patients that present with acute-on-chronic liver failure. The identification of patients at higher risk for adverse outcomes can aid in making the clinical decisions that will improve the prognosis for these patients. To determine in-hospital mortality and evaluate the epidemiologic and clinical characteristics of patients with cirrhosis of the liver seen at a tertiary referral hospital. A descriptive, observational, cohort study was conducted on adult patients with cirrhosis of the liver, admitted to a tertiary care center in Bucaramanga, Colombia, within the time frame of March 1, 2015 and February 29, 2016. Eighty-one patients with a mean age of 62 years were included in the study. The main etiology of the cirrhosis was alcoholic (59.3%). In-hospital mortality was 23.5% and the most frequent cause of death was septic shock (68.4%), followed by hypovolemic shock (10.5%). A MELD score≥18, a leukocyte count>12,000/ul, and albumin levels below<2.5g/dl were independent factors related to hospital mortality. In-hospital mortality in cirrhotic patients is high. Sepsis and bleeding are the 2 events leading to acute-on-chronic liver failure and death. A high MELD score, elevated leukocyte count, and low level of albumin are related to poor outcome during hospitalization. Adjusted prevention-centered public health measures and early and opportune diagnosis of this disease are needed to prevent the development of complications and to improve outcome in cirrhotic patients.

  1. PROSE for irregular corneas at a tertiary eye care center. (United States)

    Arumugam, Amudha Oli; Rajan, Rajni; Subramanian, Madhumathi; Mahadevan, Rajeswari


    The aim of this study was to report and discuss the clinical experience with PROSE (Prosthetic Replacement of Ocular Surface Ecosystem) practice at a tertiary eye care hospital. Retrospective data of patients who were prescribed PROSE during April 2011 to March 2012 in a tertiary eye care center in south India were analyzed. Data collected include patient demographics, indications of scleral lens fitting, previous correction modality, PROSE parameters, best-corrected visual acuity (BCVA) with spectacles, and BCVA with PROSE at initial assessment and few hours of wear. The BCVA before (with glasses) and after PROSE fitting was recorded in logMAR units. The age of the patients ranged between 13 and 68 years (male:female 60:25) with a mean age of 32.44±13.45 years. Mean BCVA improved by 0.3 logMAR units (3 lines) after fitting with PROSE. There was a statistically significant difference between pre- and post-PROSE BCVA (P=0.0001). Failure of rigid gas-permeable lens fitting or intolerance was the common indication for PROSE in corneas with irregular astigmatism (refractive conditions). The other reasons for which PROSE was prescribed were pain, photophobia, comfort, ghosting of images, and frequent loss of smaller lenses. Toric scleral haptic was indicated in 62 eyes. The diameter, vault, and haptic measurements of PROSE in ocular surface disorders were much less and flatter than that of refractive conditions. PROSE device is a very useful alternative for irregular corneas to improve visual acuity, to improve comfort, and for symptomatic relief.

  2. Survey of visual impairment in an Indian tertiary eye hospital

    Herse Peter


    Full Text Available A retrospective survey of 4, 122 consecutive patient records was performed in a tertiary care eye hospital in Hyderabad, India. Data collected included age, gender, visual acuity after completion of treatment and diagnosis. 62.8% of the patients were male. After completion of treatment, 10.8% had low vision (best corrected visual acuity <6/18 to 3/60 in the better eye and 2.6% were blind (best correct visual acuity <3/60 in the better eye. Most cases of low vision were found in the 50 to 70 year age group (42.9%. The most common visual acuity range after treatment amongst patients with vision loss was <6/18 to 6/60 (71%. The 4 main causes of low vision were cataract (21.4% of low vision group, glaucoma (14.0%, diabetic retinopathy (13.0%, and retinitis pigmentosa (10.7%. The 4 main causes of blindness were glaucoma (16.3% of blind group, diabetic retinopathy (13.2%, corneal opacities (11.6% and retinitis pigmentosa (11.6%. It is suggested that patients with low vision at the conclusion of treatment be referred to a vision rehabilitation centre. Referral should be made in cases with a best corrected visual acuity <6/18 to 3/60 or with visual field loss to within 15° of fixation. Patients aged under 50 years of age are expected to achieve maximal rehabilitation success. Motivation and vocational requirements should be assessed in older or more complex cases before referral. The data of this study show that about 10% of patients seen at a tertiary care eye hospital in India could benefit from low vision rehabilitation.

  3. Gestational Trophoblastic Disease - Clinicopathological Study at Tertiary Care Hospital. (United States)

    Jagtap, Sunil Vitthalrao; Aher, Vidhya; Gadhiya, Suchi; Jagtap, Swati Sunil


    Gestational Trophoblastic Disease (GTD) is a term used for a group of pregnancy-related tumours. These consist of various tumours and tumour like lesions characterized by proliferation of trophoblastic tissue. Amongst GTD, hydatidiform moles are the most common form. These lesions sometimes may develop into invasive moles, or, in rare cases, into choriocarcinoma. To study the clinicopathologic characteristics and prevalence of different forms of gestational trophoblastic disease in a tertiary care hospital. The present study was descriptive, observational, analytical type done in Department of Pathology at tertiary care hospital from May 2012 to April 2016. All cases clinically suspected of GTD were included and confirmation was done by histopathological study on H&E stained slides. The cases of GTD were classified according to WHO classification. Detailed histomorphological features and beta human Chorionic Gonadotropin (hCG) levels were correlated. During study period, 18345 deliveries were reported; out of which 77 cases were diagnosed as GTD. Almost 97.40% cases were of hydatidiform moles, 1.30% cases of choriocarcinoma and 1.30% cases of Placental Site Trophoblastic Tumour (PSTT). Among the cases of hydatidiform mole 57.34% were complete mole and 41.33% cases were of partial mole. The common clinical presentation was per vaginal bleeding and amenorrhea. The blood group A was most commonly observed in patient (49.35%). In majority of cases beta hCG levels were between 50,000 to 100000 mIU/ml. The correlation between beta hCG level and GTD were done. Pregnant females clinically presenting with abnormal vaginal bleeding must be evaluated for GTD. Histopathological examination is helpful for confirmatory diagnosis. Follow up of such patients is essential for early detection of malignant trophoblastic tumours.

  4. Description, measurement and evaluation of tertiary-education food environments. (United States)

    Roy, R; Hebden, L; Kelly, B; De Gois, T; Ferrone, E M; Samrout, M; Vermont, S; Allman-Farinelli, M


    Obesity in young adults is an increasing health problem in Australia and many other countries. Evidence-based information is needed to guide interventions that reduce the obesity-promoting elements in tertiary-education environments. In a food environmental audit survey, 252 outlets were audited across seven institutions: three universities and four technical and further education institutions campuses. A scoring instrument called the food environment-quality index was developed and used to assess all food outlets on these campuses. Information was collated on the availability, accessibility and promotion of foods and beverages and a composite score (maximum score=148; higher score indicates healthier outlets) was calculated. Each outlet and the overall campus were ranked into tertiles based on their 'healthiness'. Differences in median scores for each outcome measure were compared between institutions and outlet types using one-way ANOVA with post hoc Scheffe's testing, χ 2 tests, Kruskal-Wallis H test and the Mann-Whitney U test. Binomial logistic regressions were used to compare the proportion of healthy v. unhealthy food categories across different types of outlets. Overall, the most frequently available items were sugar-sweetened beverages (20 % of all food/drink items) followed by chocolates (12 %), high-energy (>600 kJ/serve) foods (10 %), chips (10 %) and confectionery (10 %). Healthy food and beverages were observed to be less available, accessible and promoted than unhealthy options. The median score across all outlets was 72 (interquartile range=7). Tertiary-education food environments are dominated by high-energy, nutrient-poor foods and beverages. Interventions to decrease availability, accessibility and promotion of unhealthy foods are needed.

  6. A Field-Scale Simulation of the Reversible Nanoparticle Adsorption for Enhancing Oil Recovery Using Hydrophilic Nanofluids (United States)

    Cao, Liyuan

    In order to develop and apply nanotechnology in oil industry, nanoparticles transport in porous media has been studied in the past few years. Theoretical modeling were carried out to evaluate nanoparticle mobility and investigate nanoparticle retention mechanism. In this study, a simulator based on Ju and Fan's mathematical model was used to study nanoparticles transport in porous media on a reservoir scale. The simulator was verified with two simulation software, Eclipse from Schlumberger and MNM1D (Micro- and Nanoparticle transport Model in porous media in 1D geometry) developed by Tosco et al. Different injection scenarios were simulated: continuous injection, slug injection, and postflush. The effect of injection time, injection rate, and slug size on oil recovery were studied. The result discovered that when nanofluids flooding is used after water flooding as tertiary recovery method, early nanofluids injection will lead to higher oil recovery, but with more nanoparticle loss. Higher injection rate of nanofluids could help improve the flooding efficiency, but not the ultimate oil recovery for field development. Also, it can cause more nanoparticle loss. Brine water postflush is recommended when doing nanoflooding. It can significantly improve the recovery of nanoparticles, and for a homogeneous or heterogeneous reservoir, oil recovery is better compared to water flooding.

  15. Recovery technologies for building materials (United States)

    Karu, Veiko; Nurme, Martin; Valgma, Ingo


    Mining industry provides building materials for construction. Civil engineers have settled the quality parameters for construction materials. When we produce high quality building materials from carbonate rock (limestone, dolostone), then the estimated waste share is 25% to 30%, depending on crushing principles and rock quality. The challenge is to find suitable technology for waste recovery. During international mining waste related cooperation project MIN-NOVATION (, partners mapped possibilities for waste recovery in mining industry and pointed out good examples and case studies. One example from Estonia showed that when we produce limestone aggregate, then we produce up to 30% waste material (fines with size 0-4mm). This waste material we can see as secondary raw material for building materials. Recovery technology for this fine grained material has been achieved with CDE separation plant. During the process the plant washes out minus 63 micron material from the limestone fines. This technology allows us to use 92% of all limestone reserves. By-product from 63 microns to 4 mm we can use as filler in concrete or as fine limestone aggregate for building or building materials. MIN-NOVATION project partners also established four pilot stations to study other mineral waste recovery technologies and solutions. Main aims on this research are to find the technology for recovery of mineral wastes and usage for new by-products from mineral mining waste. Before industrial production, testing period or case studies are needed. This research is part of the study of Sustainable and environmentally acceptable Oil shale mining No. 3.2.0501.11-0025 and the project B36 Extraction and processing of rock with selective methods -;

    Yu, Jessica; Agras, W Stewart; Bryson, Susan


    To examine how different definitions of recovery lead to varying rates of recovery, maintenance of recovery, and relapse in bulimia nervosa (BN), end-of-treatment (EOT) and follow-up data were obtained from 96 adults with BN. Combining behavioral, physical, and psychological criteria led to recovery rates between 15.5% and 34.4% at EOT, though relapse was approximately 50%. Combining these criteria and requiring abstinence from binge eating and purging when defining recovery may lead to lower recovery rates than those found in previous studies; however, a strength of this definition is that individuals who meet this criteria have no remaining disordered behaviors or symptoms.

    Full Text Available Background: The outcome of patients with acute kidney injury (AKI is highly variable. Patients who receive renal replacement therapy (RRT for similar diseases may recover differently. The factors that operate in each patient may alter the prognosis and outcome. Aims: Our study aims at identification of prognostic factors influencing recovery in patients who required hemodialysis for AKI. Material and Methods: Patients admitted in different ICUs with AKI who underwent hemodialysis in a tertiary care hospital over a three year period were included in the study. Time from day one of disease to first dialysis, hematological and biochemical parameters were noted. Patients were grouped based on the time taken for recovery of renal function following hemodialysis into group A (2 weeks. Studied parameters have been statistically analyzed to find any significant association with recovery time. Results: Out of 63 patients, 9 progressed to chronic kidney disease. In the remaining 54, Group A comprised 31 and group B 23. Out of all the factors studied, serum creatinine (7.0±1.3 vs 8.4±3.8; P=0.018, S. bicarbonate (21.7±2.8 vs 19.7±3.8; P=0.03, pH at admission (7.25±0.13 vs 7.1±0.19; P=0.048; number of hemodialysis sessions (3.5 ±1.5 vs 5±2.4; P=0.016 and time lag from day one of disease to first hemodialysis (8.6 ± 3.6 vs 11.5±5.9; P=0.007 showed significant association with recovery time. Conclusion: Recovery following AKI is influenced by factors liked delayed presentation, late initiation of hemodialysis, low pH and low bicarbonate which can predict delayed renal recovery following hemodialysis.

    Dalum, Helle; Pedersen, Inge Kryger; Cunningham, Harry


    Introduction: The recovery model has influenced mental health services and fostered new standards for best practice. However, knowledge about how mental health care professionals (HCPs) experience recoveryoriented programs is sparse. Aim/Question: This paper explores HCPs' experiences when...... in facilitating a recovery-oriented rehabilitation program in either the USA or Denmark. Results: Three themes emerged from the HCPs' reflections on changes in attitudes and practices: “Hopeful Attitude” captures a change in the HCPs' attitude toward a more positive view on the future for clients' living......, and it alters their professional practice toward a stronger focus on client's own goals during treatment. More studies are needed to further clarify how changes in HCPs' attitudes translate into changes in mental health practices....

    Kaskutas, Lee Ann; Borkman, Thomasina J; Laudet, Alexandre; Ritter, Lois A; Witbrodt, Jane; Subbaraman, Meenakshi Sabina; Stunz, Aina; Bond, Jason


    Although recovery increasingly guides substance use disorder services and policy, definitions of recovery continue to lack specificity, thereby hindering measure development and research. The goal of this study was to move the substance use disorders field beyond broad definitions by empirically identifying the domains and specific elements of recovery as experienced by persons in recovery from diverse pathways. An Internet-based survey was completed by 9,341 individuals (54% female) who self-identified as being in recovery, recovered, in medication-assisted recovery, or as having had a problem with alcohol or drugs (but no longer do). Respondents were recruited via extensive outreach with treatment and recovery organizations, electronic media, and self-help groups. The survey included 47 recovery elements developed through qualitative work followed by an iterative reduction process. Exploratory and confirmatory factor analyses were conducted using split-half samples, followed by sensitivity analyses for key sample groupings. Four recovery domains with 35 recovery elements emerged: abstinence in recovery, essentials of recovery, enriched recovery, and spirituality of recovery. The four-factor structure was robust regardless of length of recovery, 12-step or treatment exposure, and current substance use status. Four uncommon elements did not load on any factor but are presented to indicate the diversity of definitions. Our empirical findings offer specific items that can be used in evaluating recovery-oriented systems of care. Researchers studying recovery should include measures that extend beyond substance use and encompass elements such as those examined here--e.g., self-care, concern for others, personal growth, and developing ways of being that sustain change in substance use.

    Full Text Available This study investigates the impact of different schooling dimensions (primary, secondary and tertiary on the intensity of intra-state conflicts in 25 African states during the period 1989–2008. It uses fixed-effects and Generalized Methods of Moments (GMM estimators in an annualized panel data framework. Parameter estimates suggest the following (1 primary schooling broadly mitigates conflicts in Africa. However, in environments with high natural resource rents, it could ignite conflicts; (2 there is evidence, although not overwhelming, that secondary schooling potentially drives conflicts in Africa. There is also evidence that urbanization potentially drives conflicts in Africa. However, although secondary schooling and urbanization potentially drives conflicts, in environments where secondary schooling (urbanization is high, urbanization (secondary schooling mitigates conflicts; (3 there is no evidence of a strong direct positive impact of tertiary education on conflicts and conditioning on tertiary schooling, income inequality potentially drives conflicts in African states. However, in contexts where income inequality (tertiary schooling is high, tertiary schooling (inequality mitigates conflict. Two important policy implications follow from this study. First, in contexts where income inequality is high (for instance, in South Africa, governments should strive to foster tertiary education in order to reduce conflict. Second, where urbanization rates are high, they should foster both secondary and tertiary education. This study contributes to existing knowledge by clearly demonstrating the utility of distinguishing between different educational dimensions and the contexts wherein they matter for conflict mitigation in Africa.

  1. Formation Mechanism of NDMA from Ranitidine, Trimethylamine, and Other Tertiary Amines during Chloramination: A Computational Study (United States)


    Chloramination of drinking waters has been associated with N-nitrosodimethylamine (NDMA) formation as a disinfection byproduct. NDMA is classified as a probable carcinogen and thus its formation during chloramination has recently become the focus of considerable research interest. In this study, the formation mechanisms of NDMA from ranitidine and trimethylamine (TMA), as models of tertiary amines, during chloramination were investigated by using density functional theory (DFT). A new four-step formation pathway of NDMA was proposed involving nucleophilic substitution by chloramine, oxidation, and dehydration followed by nitrosation. The results suggested that nitrosation reaction is the rate-limiting step and determines the NDMA yield for tertiary amines. When 45 other tertiary amines were examined, the proposed mechanism was found to be more applicable to aromatic tertiary amines, and there may be still some additional factors or pathways that need to be considered for aliphatic tertiary amines. The heterolytic ONN(Me)2–R+ bond dissociation energy to release NDMA and carbocation R+ was found to be a criterion for evaluating the reactivity of aromatic tertiary amines. A structure–activity study indicates that tertiary amines with benzyl, aromatic heterocyclic ring, and diene-substituted methenyl adjacent to the DMA moiety are potentially significant NDMA precursors. The findings of this study are helpful for understanding NDMA formation mechanism and predicting NDMA yield of a precursor. PMID:24968236

  2. Tertiary Technical Education and Youth Integration in Brazil, Colombia and Mexico

    Claudia Jacinto


    Full Text Available Vocational training versus a traditional university education. This chapter seeks to answer the question of whether ‘tertiary technical education’ has contributed to increasing economic and social opportunity for young people in Latin America, using three case studies from Brazil, Colombia and Mexico. It examines the extent to which tertiary technical education has contributed towards democratising access to education through institutional diversification, expanded enrolment and, at least theoretically, improved access to quality employment. The analysis shows that tertiary technical education has contributed to widening of opportunities by offering an alternative form of education to new generations of young people. Tertiary technical education is more accessible, shorter in duration, has a vocational orientation, and tends to be cheaper than a university education. However, the case studies also reveal that while a tertiary technical education diploma is an asset for young people seeking employment, it nonetheless does not have the same perceived value as a traditional university education. Available data appear to indicate that graduates of tertiary technical education earn less on average than university graduates and face several challenges in the labour market. Furthermore, the studies reveal that despite the presence of highly regarded tertiary technical education institutions in all three countries, these carry less prestige and status than universities.

  3. Recovery rates, enhanced oil recovery and technological limits. (United States)

    Muggeridge, Ann; Cockin, Andrew; Webb, Kevin; Frampton, Harry; Collins, Ian; Moulds, Tim; Salino, Peter


    Enhanced oil recovery (EOR) techniques can significantly extend global oil reserves once oil prices are high enough to make these techniques economic. Given a broad consensus that we have entered a period of supply constraints, operators can at last plan on the assumption that the oil price is likely to remain relatively high. This, coupled with the realization that new giant fields are becoming increasingly difficult to find, is creating the conditions for extensive deployment of EOR. This paper provides a comprehensive overview of the nature, status and prospects for EOR technologies. It explains why the average oil recovery factor worldwide is only between 20% and 40%, describes the factors that contribute to these low recoveries and indicates which of those factors EOR techniques can affect. The paper then summarizes the breadth of EOR processes, the history of their application and their current status. It introduces two new EOR technologies that are beginning to be deployed and which look set to enter mainstream application. Examples of existing EOR projects in the mature oil province of the North Sea are discussed. It concludes by summarizing the future opportunities for the development and deployment of EOR.

  4. Mental health recovery: evaluation of a recovery-oriented training program. (United States)

    Wilrycx, G K M L; Croon, M A; van den Broek, A H S; van Nieuwenhuizen, Ch


    This study investigates the effectiveness of a recovery-oriented training program on knowledge and attitudes of mental health care professionals towards recovery of people with serious mental illness. Using data from a longitudinal study of recovery, changes in knowledge and attitudes of 210 mental health care professionals towards recovery were explored using the Recovery Attitude Questionnaire and the Recovery Knowledge Inventory. The study uses a two-group multiple intervention interrupted time-series design which is a variant of the stepped-wedge trial design. A total of six measurements occasions took place. This study shows that professionals' attitudes towards recovery from mental illness can improve with training. After two intensive recovery-oriented training sessions, mental health care professionals have a more positive attitude towards recovery in clinical practice. A recovery-oriented training program can change attitudes of mental health care professionals towards recovery of serious mental illness.

  5. Missed Injuries in Polytrauma Patients after Trauma Tertiary Survey in Trauma Intensive Care Unit. (United States)

    Tammelin, E; Handolin, L; Söderlund, T


    Injuries are often missed during the primary and secondary surveys in trauma patients. Studies have suggested that a formal tertiary survey protocol lowers the number of missed injuries. Our aim was to determine the number, severity, and consequences of injuries missed by a non-formalized trauma tertiary survey, but detected within 3 months from the date of injury in trauma patients admitted to a trauma intensive care unit. We conducted a cohort study of trauma patients admitted to a trauma intensive care unit between 1 January and 17 October 2013. We reviewed the electronic medical records of patients admitted to the trauma intensive care unit in order to register any missed injuries, their delay, and possible consequences. We classified injuries into four types: Type 0, injury detected prior to trauma tertiary survey; Type I, injury detected by trauma tertiary survey; Type II, injury missed by trauma tertiary survey but detected prior to discharge; and Type III, injury missed by trauma tertiary survey and detected after discharge. During the study period, we identified a total of 841 injuries in 115 patients. Of these injuries, 93% were Type 0 injuries, 3.9% were Type I injuries, 2.6% were Type II injuries, and 0,1% were Type III injuries. Although most of the missed injuries in trauma tertiary survey (Type II) were fractures (50%), only 2 of the 22 Type II injuries required surgical intervention. Type II injuries presumably did not cause extended length of stay in the intensive care unit or in hospital and/or morbidity. In conclusion, the missed injury rate in trauma patients admitted to trauma intensive care unit after trauma tertiary survey was very low in our system without formal trauma tertiary survey protocol. These missed injuries did not lead to prolonged hospital or trauma intensive care unit stay and did not contribute to mortality. Most of the missed injuries received non-surgical treatment. © The Finnish Surgical Society 2016.

    Full Text Available BACKGROUND Anaemia causes a reduction in the oxygen carrying capacity of the blood resulting in tissue hypoxia. Cardiac output at rest is not usually increased in most chronic anaemia until haemoglobin levels fall below 7 g/dL, but abnormal rise in output with exercise may occur with levels as high as 10 g/dL. The increase in cardiac output has been observed to correlate well with the degree of anaemia. Other compensatory mechanisms to chronic anaemia available to the body include decreased circulation time and increased tissue oxygen uptake. The latter is facilitated by a shift to the right of the oxygen haemoglobin dissociation curve. Cardiomegaly may also be as a result of the increased workload on the heart from the increased viscosity of blood in anaemia patients. Anaemia in the elderly is an extremely common problem that is associated with increased mortality and poorer health-related quality of life, regardless of the underlying cause of the low haemoglobin. A study of anaemia in elderly patients found a wide variation in prevalence, ranging from 2.9% to 61% in men and 3.3% to 41% in women. Higher rates were found in hospitalised patients than in community dwellers. It is easy to overlook anaemia in the elderly, since such symptoms as fatigue, weakness, or shortness of breath may be attributed to the ageing process itself. Our objective is to show the prevalence of anaemia even in a tertiary health care centre. METHODS One hundred patients were identified who were admitted in the Department of Medicine, Deccan College of Medical Sciences. Among the 100 patients, 38 were male and 62 were female. The study was conducted from Jan 2014 To Jan 2015. Patients having haemoglobin less than 10 g% in the medical wards were enrolled in the study. RESULTS Among the 100 patients, 38 were male and 62 were female. The average haemoglobin was 6.4 g%, the lowest being 2.8 g%. Peripheral blood smear showed hypochromic picture in 58, macrocytic picture in

  10. Addiction recovery: its definition and conceptual boundaries. (United States)

    White, William L


    The addiction field's failure to achieve consensus on a definition of "recovery" from severe and persistent alcohol and other drug problems undermines clinical research, compromises clinical practice, and muddles the field's communications to service constituents, allied service professionals, the public, and policymakers. This essay discusses 10 questions critical to the achievement of such a definition and offers a working definition of recovery that attempts to meet the criteria of precision, inclusiveness, exclusiveness, measurability, acceptability, and simplicity. The key questions explore who has professional and cultural authority to define recovery, the defining ingredients of recovery, the boundaries (scope and depth) of recovery, and temporal benchmarks of recovery (when recovery begins and ends). The process of defining recovery touches on some of the most controversial issues within the addictions field.

  11. Hydrogeophysical methods for analyzing aquifer storage and recovery systems. (United States)

    Minsley, Burke J; Ajo-Franklin, Jonathan; Mukhopadhyay, Amitabha; Morgan, Frank Dale


    Hydrogeophysical methods are presented that support the siting and monitoring of aquifer storage and recovery (ASR) systems. These methods are presented as numerical simulations in the context of a proposed ASR experiment in Kuwait, although the techniques are applicable to numerous ASR projects. Bulk geophysical properties are calculated directly from ASR flow and solute transport simulations using standard petrophysical relationships and are used to simulate the dynamic geophysical response to ASR. This strategy provides a quantitative framework for determining site-specific geophysical methods and data acquisition geometries that can provide the most useful information about the ASR implementation. An axisymmetric, coupled fluid flow and solute transport model simulates injection, storage, and withdrawal of fresh water (salinity ∼500 ppm) into the Dammam aquifer, a tertiary carbonate formation with native salinity approximately 6000 ppm. Sensitivity of the flow simulations to the correlation length of aquifer heterogeneity, aquifer dispersivity, and hydraulic permeability of the confining layer are investigated. The geophysical response using electrical resistivity, time-domain electromagnetic (TEM), and seismic methods is computed at regular intervals during the ASR simulation to investigate the sensitivity of these different techniques to changes in subsurface properties. For the electrical and electromagnetic methods, fluid electric conductivity is derived from the modeled salinity and is combined with an assumed porosity model to compute a bulk electrical resistivity structure. The seismic response is computed from the porosity model and changes in effective stress due to fluid pressure variations during injection/recovery, while changes in fluid properties are introduced through Gassmann fluid substitution.

  12. Heat recovery equipment for engines

    Energy Technology Data Exchange (ETDEWEB)

    Segaser, C.L.


    The recovery and use of waste heat from prime movers is an important consideration for evaluating an on-site power system, since it is the basic factor that makes possible a substantial increase in fuel-use efficiency. The equipment usually employed to recover waste heat can be categorized as: (a) shell-and-tube type heat exchangers, (b) radiator-type heat exchangers, (c) exhaust gas boilers for the generation of pressurized hot water and/or steam, (d) steam separators, and (e) combined packaged units for ebulliently cooled internal combustion piston engines. The functional requirements and cost considerations involved in applying these devices for the recovery of waste heat from various types of prime-movers considered for application in the ICES Systems Engineering Program are examined.

  13. Buddhist Approaches to Addiction Recovery

    Directory of Open Access Journals (Sweden)

    Paramabandhu Groves


    Full Text Available The Buddha recognized addiction problems and advised his followers accordingly, although this was not the primary focus of his teachings. Thailand and Japan, which have long-standing Buddhist traditions, have developed Buddhist influenced responses to addiction. With its emphasis on craving and attachment, an understanding of the workings of the mind, as well as practices to work with the mind, Buddhism lends itself as a rich resource to assist addiction recovery. The twelve step movement has been an impetus to making use of ideas and practices from Buddhism. In particular, mindfulness, has started to be used to support addiction recovery, with promising results. Exploration of other areas of Buddhism is beginning, and may provide additional benefit in the future.

    Full Text Available Spontaneous recovery represents the only hope of regaining autonomy, for the majority of stoke victims especially in developing countries like Morocco. This recovery is mainly based on the brain’s reorganization capacities, referred to as “adaptive plasticity”. Rehabilitation is one of the most powerful modulators of brain plasticity that, if well administered, can improve post-injury recovery.

  18. Timely thoracoscopic decortication promotes the recovery of paediatric parapneumonic empyema. (United States)

    Lau, C T; Fung, C H; Wong, K K Y; Tam, P


    Parapneumonic empyema is one of the most commonly encountered yet difficult to manage paediatric thoracic conditions. Conservative treatment with chest tube drainage and fibrinolytic agents had been proposed but operative decortication remains the gold standard for refractory cases. Thoracoscopic decortication has been advocated in recent years due to its superiority in terms of post-operative pain, cosmesis and other long-term results. However, few studies investigated the effect of timing on peri-operative outcomes. This study aims to explore the benefits of early decortication. Retrospective study of all patients who underwent thoracoscopic decortication between 1999 and 2013 at a tertiary referral centre was performed. Data were extracted from respective medical records. Patients' demographics, peri-operative outcomes, length of hospitalization and post-operative complications were analysed. A total of 28 patients were identified, 12 males and 16 females. Average age of patients was 4.5 years (range 12 months-14 years). Right-sided empyema was involved in 14 of the patients. Patients who underwent operation within 2 weeks from symptom onset (n = 16) showed significant shorter post-operative hospital stay (mean 9.5 vs 20.4 days, p = 0.003) and total hospitalization duration (mean 19.3 vs 38.8 days, p decortication for residual empyema. Thoracoscopic decortication is a safe and feasible procedure for parapneumonic empyema. Timely surgery is recommended as it promotes early recovery and shorter hospitalization.

  19. New interpretation of development of San Luis basin, south-central Colorado, based on petrology of Tertiary strata

    Energy Technology Data Exchange (ETDEWEB)

    Brister, B.S. (New Mexico Institute of Mining and Technology, Socorro (USA))


    A problem exists in determining which parts of the San Luis basin were depositional sites during three Tertiary tectonic events: early Tertiary (Laramide) transpression/compression, mid-Tertiary volcanism, and late Tertiary (Rio Grande rift) extension. Earlier studies have been hampered by incomplete knowledge of regional characteristics of poorly exposed early Tertiary rocks and by reliance upon inconclusive pollen age determinations. For simple petrologic analysis of well cuttings from boreholes across the basin, the authors must reinterpret the timing and mode of basin development. Applying general petrologic characteristics in well log correlations, it is apparent that the western part (Monte Vista graben) of the San Luis basin was an active depositional basin during all three of the Tertiary tectonic events, whereas the eastern part (Baca graben) is primarily a result of the late Tertiary rift episode.

  20. Submarine pyroclastic deposits in Tertiary basins, NE Slovenia

    Directory of Open Access Journals (Sweden)

    Polona Kralj


    Full Text Available In Tertiary basins of NE Slovenia, Upper Oligocene volcanic activity occurred in a submarine environment that experienced contemporaneous clastic sedimentation. Pyroclastic deposits are essentially related to gas- and watersupported eruption-fed density currents. At Trobni Dol, the Lako Basin, an over 100 m thick deposit formed by a sigle sustained volcanic explosion that fed gas-supported pyroclastic flow. Diagnostic features are large matrixshard content, normal grading of pumice lapilli, collapsed pumice lapilli and the presence of charcoal. In the Smrekovec Volcanic Complex, several but only up to 5 m thick deposits related to eruption-fed gassupported pyroclastic flows occur. Deposits settled from water-supported eruption-fed density currents form fining- and thinning-upward sedimentary units which resemble the units of volcaniclastic turbidites. Pyroclastic deposits related to gas- and water-supported density currents occur in an up to 1000 m thick succession composed of coherent volcanics, autoclastic, pyroclastic, reworked volcaniclastic and mixed volcaniclastic-siliciclastic deposits that indicate a complex explosive and depositional history of the Smrekovec Volcanic Complex.

    Baruch, Y; Swartz, M; Sirkis, S; Mirecki, I; Barak, Y


    Mental health professionals are at a high risk of burnout. Positive psychology outcomes of staff in acute in-patient psychiatric wards are poorly researched and unclear. To quantify the satisfaction with life and work-life satisfaction of mental health staff at a large university-affiliated tertiary psychiatric centre. We utilized the Satisfaction with Life Scale (SWLS) and the Work-Life Satisfaction Questionnaire (WLSQ). Two hundred and nine out of 450 staff members (46%) participated; mean age 48.2 + 9.9 years; 63% were male. On average the participants had been practising their speciality for 21.1 + 9.8 years (range: 2-48). The mean total SWLS scores differed significantly between professions (P happiness were reported by psychologists and social workers, followed by the administrative staff, the psychiatrists and finally the nursing staff. Staff scored the highest for work as a 'calling' followed by work as a 'career' and the lowest rating for work as a 'job'. The mean total WLSQ score differed between professions, (P happiness may contribute to increase in moral and counter burnout.

  2. Factors Hindering the Integration of CALL in a Tertiary Institution

    Directory of Open Access Journals (Sweden)

    Izaham Shah Ismail


    Full Text Available The field of Computer Assisted Language Learning (CALL is a field that is constantly evolving as it is very much dependent on the advancement of computer technologies. With new technologies being invented almost every day, experts in the field are looking for ways to apply these new technologies in the language classroom. Despite that, teachers are said to be slow at adopting technology in their classrooms and language teachers, whether at schools or tertiary institutions, are no exception. This study attempts to investigate the factors that hinder ESL instructors at an institution of higher learning from integrating CALL in their lessons. Interviews were conducted with five ESL instructors and results revealed that factors which hinder them from integrating CALL in their teaching are universal factors such as knowledge in technology and pedagogy, computer facilities and resources, absence of exemplary integration of CALL, personal beliefs on language teaching, views on the role of a computers as teacher, and evaluation of learning outcomes.

    To describe our experience using Minimally Invasive Surgery (MIS) techniques in tertiary center with specific oncological pediatric surgery unit. Retrospective review of patients undergoing MIS techniques in pediatric oncology surgery unit between January 2011 and December 2014. MIS procedures were considered made by both techniques such as laparoscopy and thoracoscopy with both diagnostic and therapeutic intent. 4 procedures were diagnostic and the rest were therapeutic: During the study, 56 procedures were performed by MIS. By type of technique, 13 were thoracoscopic (7 metastasectomies, 6 thoracic masses) and 43 laparoscopic (3 hepatic masses, 3 pancreatic masses 7 abdominal masses, 2 ovarian masses, 2 typhlitis 1 splenic mass and 25 oophorectomy for ovarian cryopreservation). In 5 cases (2 thoracic masses 1 pancreatic mass abdominal masses) conversion to open surgery to complete the procedure (2 for caution in the absence of vascular control bleeding 1 and 2 for lack of space) was necessary. In all cases safety principles of oncological surgery were respected. Providing an adecuate selection of patiens, MIS techniques are safe, reproducible and fulfill the objectives of quality of cancer surgery.

  4. Wildfires and animal extinctions at the Cretaceous/Tertiary boundary (United States)

    Adair, Robert K.


    Persuasive models of the ejection of material at high velocities from the Chicxulub asteroid impact marking the Cretaceous/Tertiary boundary have led to the conclusion that upon return, that material, heated in passage through the upper atmosphere, generated a high level of infrared energy density over the Earth's surface. That radiant energy has been considered to be a direct source of universal wildfires, which were presumed to be a major cause of plant and animal species extinctions. The extinction of many animal species, especially the dinosaurs, has also been attributed to the immediate lethal effects of the radiation. I find that the absorption of the radiation by the atmosphere, by cloud formations, and by ejecta drifting in the lower atmosphere reduced the radiation at the surface to a level that cannot be expected to have generated universal fires. Although the reduced radiation will have likely caused severe injuries to many animals, such insults alone seem unlikely to have generated the overall species extinctions that have been deduced.

    Full Text Available Background : We assessed job satisfaction among anesthesiologists at a tertiary hospital in Nigeria and identified elements of job stress and dissatisfaction. Methods : A cross-sectional study design was employed; a structured self-administered questionnaire was distributed, which focused on sociodemographic data, rating of job satisfaction, identification of stressors, and work relationships. Results : Out of 55 questionnaires distributed, 46 (83.6% completed questionnaires were returned. Overall, 27 (58.7% of the anesthesiologists were satisfied with their job. While 8.7% were very satisfied (grade 5, 6.5% were very dissatisfied (grade 1 with their job. The stressors identified by the respondents were time pressures, long working hours with complaints of insufficient sleep, and employment status. Among the respondents, the medical officers were the most discontented (9 out of 12, 75%, followed by senior registrars (5 out of 9, 56%. A high percentage of participants (54.1% declared that the one change if implemented that would enhance their job satisfaction was having a definite closing time. Conclusion : Our results showed that despite the demanding nature of anesthesiology as a specialty, many anesthesiologists were contented with their job.

  6. Predictors of Patient Satisfaction with Tertiary Hospitals in Korea

    Directory of Open Access Journals (Sweden)

    Hye-Sook Ham


    Full Text Available This study examined the general and system-related predictors of outpatient satisfaction with tertiary health care institutions in Korea. A cross-sectional descriptive study design was employed. The subjects were 1,194 outpatients recruited from 29 outpatient clinics of a university medical center in Korea. Measurements included 5 outpatient service domains (i.e., doctor service, nurse service, technician service, convenience, and physical environment of facility and patient satisfaction. Of the five domains, nurse service was the domain with the highest mean score M=4.21 and convenience was the domain with the lowest mean score M=3.77. The most significant predictor of patient satisfaction was the constructs of convenience β=0.21. The results of this study suggest that the concept of patient satisfaction with health care institutions in modern hospitals reflects an integrative process that includes not only the concerned health care personnel but also improved convenience such as user-friendly reservation system and comfortable waiting areas.

    Full Text Available Background: Accidental needle stick injuries (NSIs are an occupational hazard for healthcare workers (HCWs. A recent increase in NSIs in a tertiary care hospital lead to a 1-year review of the pattern of injuries, with a view to determine risk factors for injury and potential interventions for prevention. Methods: We reviewed 1-year (July 2006-June 2007 of ongoing surveillance of NSIs. Results: The 296 HCWs reporting NSIs were 84 (28.4% nurses, 27 (9.1% nursing interns, 45 (21.6% cleaning staff, 64 (21.6% doctors, 47 (15.9% medical interns and 24 (8.1% technicians. Among the staff who had NSIs, 147 (49.7% had a work experience of less than 1 year ( P < 0.001. The devices responsible for NSIs were mainly hollow bore needles ( n = 230, 77.7%. In 73 (24.6% of the NSIs, the patient source was unknown. Recapping of needles caused 25 (8.5% and other improper disposal of the sharps resulted in 55 (18.6% of the NSIs. Immediate post-exposure prophylaxis for HCWs who reported injuries was provided. Subsequent 6-month follow-up for human immunodeficiency virus showed zero seroconversion. Conclusion: Improved education, prevention and reporting strategies and emphasis on appropriate disposal are needed to increase occupational safety for HCWs.

    The prevalence of mucormycosis is reportedly high in India, although the studies are mainly from north and south India only. We analysed the mucormycosis cases at tertiary care centres of West India. We retrieved the clinical details of all the patients with probable and proven mucormycosis diagnosed at Sterling Hospital and ID clinic at Ahmedabad, Gujarat over the period from 1 January 2013 through 30 April 2015. The data were analysed to determine demography, risk factors, underlying diseases, site of infection and outcome of these patients. A total of 27 patients with the median age of 50 (16-65) years were diagnosed with mucormycosis during the period. Rhino-orbital-cerebral mucormycosis was the most common (51.9%) presentation. Majority (55.6%) of the patients had uncontrolled diabetes with or without ketoacidosis; 25.9% patients had no underlying disease and most of them (85.7%) had cutaneous mucormycosis. In this group, the mortality was 25.9% and an equal percentage of patients were lost to follow up; 14 (51.9%) patients could complete 6 weeks of amphotericin B therapy. All patients who completed antifungal therapy survived except one. Like other parts of India, uncontrolled diabetes was the predominant risk factor for mucormycosis in our group. Patients completing 6 weeks of amphotericin B treatment were likely to survive. © 2017 Blackwell Verlag GmbH.

    Nashrath, Mariyam; Akkadechanunt, Thitinut; Chontawan, Ratanawadee


    The present study explored nurses' and patients' expectations of nursing service quality, their perception of performance of nursing service quality performed by nurses, and compared nursing service quality, as perceived by nurses and patients. The sample consisted of 162 nurses and 383 patients from 11 inpatient wards/units in a tertiary care hospital in the Maldives. Data were collected using the Service Quality scale, and analyzed using descriptive statistics and the Mann-Whitney U-test. The results indicated that the highest expected dimension and perceived dimension for nursing service quality was Reliability. The Responsiveness dimension was the least expected dimension and the lowest performing dimension for nursing service quality as perceived by nurses and patients. There was a statistically significant difference between nursing service quality perceived by nurses and patients. The study results could be used by nurse administrators to develop strategies for improving nursing service quality so that nursing service delivery process can be formulated in such a way as to reduce differences of perception between nurses and patients regarding nursing service quality. © 2011 Blackwell Publishing Asia Pty Ltd.

    The terpenoid composition and class of Tertiary resins preserved within lignites of Cambay, Kutch and Cauvery Basins of India have been characterized using Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GC-MS) and Fourier Transform Infrared (FTIR) Spectroscopy. Major pyrolysis products include cadalene-based C{sub 15}-bicyclic sesquiterpenoids with some C{sub 30} and C{sub 31} bicadinanes and bicadinenes typical of Class II or dammar resin. The occurrence of these terpenoids in Early Eocene sediments may extend the first appearance of Dipterocarpaceae angiosperms, the predominant source of this resin class, back to the Early Eocene epoch in India. The same terpenoid biomarkers have been detected in many SE Asian oils reflecting a close source relationship with these resins. Strong CH{sub 3} (1377 cm{sup -} {sup 1}) and other CH{sub x} (3000-2800 and 1460-1450 cm{sup -} {sup 1}) aliphatic absorptions of much larger intensity than the aromatic C = C (1560-1650 cm{sup -} {sup 1}) absorption were detected in the Indian resins by FTIR Spectroscopy, confirming the quantitative significance of the terpenoid pyrolysates.

  11. Septic arthritis in adults in a tertiary care center. (United States)

    Ornelas-Aguirre, José Manuel


    To describe the history, clinical features and microorganisms involved in a group of adult subjects with and without septic arthritis (SA) at a tertiary care in Mexico. A cross-sectional descriptive study was conducted on 96 adults with clinical suspicion of AS in one or more joints. In all cases synovial fluid arthrocentesis and culture was performed. The comparison group subjects were culture negative. A descriptive statistical analysis and binary logistic regression model was performed between the variables associated with the development of AS. A value of P≤.05 was significant. A total of 49 out of 96 subjects had a positive culture, mostly of the monoarticular type (96%; P=.02). The knee was the most common site (61%; P=.06) and pain was the main clinical manifestation (59%; P=.001). Staphylococcus was the most common etiological agent (65%; P<.001). The risk factors revealed in the final regression model were SA the history of joint disease (OR=25; P=.03) and volume increase (OR=13.16; P=.06). Functional limitation (OR=8.54; P=.04) showed a significant risk among borderline for SA. Our results are consistent with previous studies, and can be generalized to geographical areas with similar clinical features to those observed in this study.

    Full Text Available Introduction. Mastalgia is a common breast condition among women referred to breast clinics worldwide. Whereas the prevalence is known in the Western world and Asia, the prevalence of the disease is unknown in many African countries. The aim of this study therefore was to determine the prevalence and describe factors associated with mastalgia among women attending a tertiary hospital in sub-Saharan Africa. Methods. A cross-sectional study was done in Kampala, Uganda. Mastalgia was defined as self-reported breast pain (unilateral or bilateral for a period not less than two months. A pretested questionnaire was used to collect the data and statistical analysis was performed using SPSS version 11. Ethical approval was obtained. Results. Out of the 1048 women who presented to the breast clinic during the study period, 168 (16% were diagnosed with mastalgia in the absence of breast cancer. Noncyclical and cyclical mastalgia were 22/168 (13% and 5/168 (3%, respectively. The onset of noncyclical category as compared to the cyclical type of mastalgia was observed to manifest before 24 years of age (P=0.006. Conclusion. Mastalgia was a common condition among women in this sub-Saharan African setting as is elsewhere. The early onset mastalgia in this sub-Saharan African study requires further exploration for determination of its risk factors.

    To evaluate the epidemiology of ankle fractures surgically treated at the Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Universidade de São Paulo. Medical records of patients admitted with foot and ankle fractures between 2006 and 2011 were revised. Seventy three ankle fractures that underwent surgical treatment were identified. The parameters analyzed included age, gender, injured side, AO and Gustilo & Anderson classification, associated injuries, exposure, need to urgent treatment, time to definitive treatment and early post-operative complications. retrospective epidemiological study. Male gender was predominant among subjects and the mean age was 27.5 years old. Thirty nine fractures resulted from traffic accidents and type B fracture according to AO classification was the most common. Twenty one were open fractures and 22 patients had associated injuries. The average time to definitive treatment was 6.5 days. Early post-operative complications were found in 21.3% of patients. Ankle fractures treated in a tertiary hospital of a large city in Brazil affect young people victims of high-energy accidents and present significant rates of associated injuries and post-operative complications.

    Al-Mahrouqi, Haitham H; Al-Harthi, Naila; Al-Wahaibi, Maryam; Hanumantharayappa, Kishore


    To describe the epidemiology of ocular trauma in a tertiary hospital setting in Muscat, Oman. Medical records of all cases of ocular trauma which presented to the Emergency Department at Al-Nahdha Hospital and were seen by the ophthalmology service from January 1, 2013 to June 30, 2013 (6 months) were reviewed to collect data on ocular trauma according to the World Eye Injury Registry initial reporting form which uses the Birmingham Eye Trauma Terminology System. There were 27,951 patients seen at the Emergency Department and 611 of which were ocular trauma cases (cumulative incidence 2.2% [confidence interval 2.0-2.4]). The mean age of the patients was 23 years and males comprised the majority of the cases (72%). Thirty-two patients had bilateral injury giving a total of 643 eyes injured. More than half of all injuries were caused by either blunt or large sharp objects. The cornea was the most frequently injured tissue (49%), but most injuries were minor in nature. More than three quarters (77%) of all eyes had a visual acuity of 0.3 (LogMAR) or better on presentation. There were 35 eyes (6%) with open globe injuries (OGI) and three-quarters of them occurring in the manual laborers. Ocular trauma is a common presentation at Al-Nahdha Hospital. Although the majority of trauma cases were minor without any visual disability sequelae, OGI could have been prevented with better ocular protection in the workplace.

  15. Experience of intravitreal injections in a tertiary Hospital in Oman. (United States)

    Al-Hinai, Ahmed S


    To find out statistical data regarding intravitreal injections in an outpatient department setup at a tertiary center in Oman. Retrospective chart review. Data collection of patients who underwent intravitreal injections from November 2009 to May 2013 at Sultan Qaboos University Hospital. Throughout a period of 42 months, a total of 711 intravitreal injections were performed. That included 214 patients (275 eyes). Around one-third of the eyes received two injections or more. The injected agents were bevacizumab (59.8%), ranibizumab (32.3%), triamcinolone (7.5%), and very few patients with endophthalmitis received intravitreal antibiotics and antifungal agents. The three most common indications for the injection therapy were diabetic macular edema (50.9%), choroidal neovascularization (24.3%), and retinal vein occlusive diseases (11.5%). Serious adverse events were rare, and they occurred as ocular (0.9% per patient) and systemic (3.3% per patient). There were 42 eyes received intravitreal triamcinolone, and 24% of them developed intraocular hypertension that required only medical treatment. Different intravitreal agents are currently used to treat many ocular diseases. Currently, therapy with intravitreal agents is very popular, and it carries a promising outcome with more efficiency and safety.

  17. Tertiary Lymphoid Organs in Central Nervous System Autoimmunity

    Directory of Open Access Journals (Sweden)

    Meike Mitsdoerffer


    Full Text Available Multiple sclerosis (MS is an autoimmune disease characterized by chronic inflammation in the central nervous system (CNS, which results in permanent neuronal damage and substantial disability in patients. Autoreactive T cells are important drivers of the disease, however, the efficacy of B cell depleting therapies uncovered an essential role for B cells in disease pathogenesis. They can contribute to inflammatory processes via presentation of autoantigen, secretion of pro-inflammatory cytokines and production of pathogenic antibodies. Recently, B cell aggregates reminiscent of tertiary lymphoid organs (TLOs were discovered in the meninges of MS patients, leading to the hypothesis that differentiation and maturation of autopathogenic B and T cells may partly occur inside the CNS. Since these structures were associated with a more severe disease course, it is extremely important to gain insight into the mechanism of induction, their precise function and clinical significance. Mechanistic studies in patiens are limited. However, a few studies in the MS animal model experimental autoimmune encephalomyelitis (EAE recapitulate TLO formation in the CNS and provide new insight into CNS TLO features, formation and function. This review summarizes what we know so far about CNS TLOs in MS and what we have learned about them from EAE models. It also highlights the areas that are in need of further experimental work, as we are just beginning to understand and evaluate the phenomenon of CNS TLOs.

    Full Text Available BACKGROUND Birth defects are responsible for increased perinatal mortality and long-term morbidities. To reduce its incidence, which is the need of the hour we should know more about them and possible risk factors, which can be prevented. The aim of the study is to study the overall frequency of birth defects in a tertiary hospital and search for association with certain risk factors. MATERIALS AND METHODS All newborns/stillborns with birth defects during one year were enrolled for the study. Similar number of newborns without birth defect during this period was taken as control. Relevant information was documented in both the groups and analysed. RESULTS Out of 11,008 births, congenital anomaly was found in 130 cases. The prevalence of birth defects was 1.18 percent. Association of occurrence of birth defects with increased paternal age, consanguinity, fever and drug intake in first trimester was found. 57.6% of the newborns with birth defects were stillborn, born at an earlier gestational age (33.6 week v/s. 37.5 weeks. Commonest system to be affected was CNS (49.2%. CONCLUSION Screening for aneuploidy and birth defects should be universal. Routine folic acid supplementation and pregnancy termination of malformed babies will reduce the incidences.

  19. After-hour physiotherapy services in a tertiary general hospital. (United States)

    Lim, Edwin C W; Liu, Jinyu; Yeung, Meredith T L; Wong, Wai Pong


    The aims of the present study were to describe the after-hour physiotherapy services in a tertiary general hospital, the patients and their demographics, and to determine which independent variables would predict physiotherapists' referrals to after-hour physiotherapy. A retrospective record review from April 1, 2004, to April 30, 2005, identified 992 patients (mean age 63.8 years; 95% confidence interval [CI] 62.6-65.0 years) who were either referred by daytime physiotherapists (68%) or referred by medical practitioners for urgent attendance after hours (32%). Pneumonia was formally diagnosed medically in 20% (n=197) of the patients. Of all the patients who had surgery, upper abdominal or thoracic incisions formed the majority (61%; n=236). Whether patients had upper abdominal/thoracic surgery (estimated odds ratio 3.4; 95% CI 2.3-4.9) and the presence of pneumonia (2.8; 95% CI 1.9-4.2) were two independent factors identified from a logistic regression model predicting daytime physiotherapists' referral of patients to after-hour service. This model correctly predicted 65.5% of the cases. Most patients were seen for mucociliary clearance. Referral behaviour by physiotherapists reflects the basis of their clinical decision making and has implications for practice, training, and further research.

  20. Reduction of secondary and tertiary phosphine oxides to phosphines. (United States)

    Hérault, Damien; Nguyen, Duc Hanh; Nuel, Didier; Buono, Gérard


    Achiral or chiral phosphines are widely used in two main domains: ligands in organometallic catalysis and organocatalysis. For this reason, the obtention of optically pure phosphine has always been challenging in the development of asymmetric catalysis. The simplest method to obtain phosphines is the reduction of phosphine oxides. The essential difficulty is the strength of the P=O bond which involves new procedures to maintain a high chemio- and stereoselectivity. The reduction can occur with retention or inversion of the stereogenic phosphorus atom depending on the nature of the reducing agent and the presence of additives. In fact, the reactivity of the phosphine oxides and the mechanism of the reduction are not always well understood. Since the first work in the 1950's, numerous studies have been realised in order to develop methodologies with different reagents or to understand the mechanism of the reaction. In the last decade, efficient stereospecific methodologies have been developed to obtain optically pure tertiary phosphines from P-stereogenic phosphine oxides. In this review, we intend to provide a comprehensive and critical overview of these methodologies.

  2. Uses and abuses of recovery: implementing recovery-oriented practices in mental health systems. (United States)

    Slade, Mike; Amering, Michaela; Farkas, Marianne; Hamilton, Bridget; O'Hagan, Mary; Panther, Graham; Perkins, Rachel; Shepherd, Geoff; Tse, Samson; Whitley, Rob


    An understanding of recovery as a personal and subjective experience has emerged within mental health systems. This meaning of recovery now underpins mental health policy in many countries. Developing a focus on this type of recovery will involve transformation within mental health systems. Human systems do not easily transform. In this paper, we identify seven mis-uses ("abuses") of the concept of recovery: recovery is the latest model; recovery does not apply to "my" patients; services can make people recover through effective treatment; compulsory detention and treatment aid recovery; a recovery orientation means closing services; recovery is about making people independent and normal; and contributing to society happens only after the person is recovered. We then identify ten empirically-validated interventions which support recovery, by targeting key recovery processes of connectedness, hope, identity, meaning and empowerment (the CHIME framework). The ten interventions are peer support workers, advance directives, wellness recovery action planning, illness management and recovery, REFOCUS, strengths model, recovery colleges or recovery education programs, individual placement and support, supported housing, and mental health trialogues. Finally, three scientific challenges are identified: broadening cultural understandings of recovery, implementing organizational transformation, and promoting citizenship.

  3. Tertiary instability of zonal flows within the Wigner-Moyal formulation of drift turbulence (United States)

    Zhu, Hongxuan; Ruiz, D. E.; Dodin, I. Y.


    The stability of zonal flows (ZFs) is analyzed within the generalized-Hasegawa-Mima model. The necessary and sufficient condition for a ZF instability, which is also known as the tertiary instability, is identified. The qualitative physics behind the tertiary instability is explained using the recently developed Wigner-Moyal formulation and the corresponding wave kinetic equation (WKE) in the geometrical-optics (GO) limit. By analyzing the drifton phase space trajectories, we find that the corrections proposed in Ref. to the WKE are critical for capturing the spatial scales characteristic for the tertiary instability. That said, we also find that this instability itself cannot be adequately described within a GO formulation in principle. Using the Wigner-Moyal equations, which capture diffraction, we analytically derive the tertiary-instability growth rate and compare it with numerical simulations. The research was sponsored by the U.S. Department of Energy.

    Full Text Available We describe the characteristics of patients attending an Australian tertiary multidisciplinary pain service and identify areas for nutrition interventions. This cross-sectional study targets patients experiencing chronic pain who attended the service between June–December 2014. Self-reported data was captured from: (1 an Electronic Persistent Pain Outcomes Collaboration (ePPOC referral questionnaire, incorporating demographics, pain status, and mental health; (2 a Pain Assessment and Recovery Plan (PARP, which documents patients’ perceived problems associated with pain and personal treatment goals. The ePPOC referral questionnaire was completed by 166 patients and the PARP by 153. The mean (SD patient age was 53 ± 13 years, with almost 60% experiencing pain for >5 years. Forty-five percent of patients were classified as obese (BMI ≥ 30 kg/m2, mean (SD BMI was 31 ± 7 kg/m2, with a mean waist circumference of 104 ± 19.4 cm (SD. The most frequent patient nominated treatment goals related to physical activity (39%, followed by nutritional goals (23%. Traditionally, pain management programs have included physical, psychosocial, and medical, but not nutritional, interventions. By contrast, patients identified and reported important nutrition-related treatment goals. There is a need to test nutrition treatment pathways, including an evaluation of dietary intake and nutrition support. This will help to optimize dietary behaviors and establish nutrition as an important component of multidisciplinary chronic pain management.

    The relationship between recovery and fatigue and its impact on performance has attracted the interest of sports science for many years. An adequate balance between stress (training and competition load, other life demands) and recovery is essential for athletes to achieve continuous high-level performance. Research has focused on the examination of physiological and psychological recovery strategies to compensate external and internal training and competition loads. A systematic monitoring of recovery and the subsequent implementation of recovery routines aims at maximizing performance and preventing negative developments such as underrecovery, non-functional overreaching, the overtraining syndrome, injuries, or illnesses. Due to the inter- and intra-individual variability of responses to training, competition, and recovery strategies, a diverse set of expertise is required to address the multifaceted phenomena of recovery, performance and their interactions to transfer knowledge from sports science to sports practice. For this purpose, a symposium on Recovery and Performance was organized at the Technical University Munich Science and Study Center Raitenhaslach (Germany) in September 2016. Various international experts from many disciplines and research areas gathered to discuss and share their knowledge of recovery for performance enhancement in a variety of settings. The results of this meeting are outlined in this consensus statement that provides central definitions, theoretical frameworks, as well as practical implications as a synopsis of the current knowledge of recovery and performance. While our understanding of the complex relationship between recovery and performance has significantly increased through research, we also elaborate some important issues for future investigations.

  12. The Stigma of Mental Illness and Recovery. (United States)

    Avdibegović, Esmina; Hasanović, Mevludin


    Stigma and recovery "from" and "in" mental illness are associated in many various ways. While recovery gives opportunities, makes person stronger, gives purpose and meaning to their lives and leads to social inclusion, in the same time stigma reduces opportunities, reduces self-esteem and self-efficacy, reduces the belief in own abilities and contributes to social exclusion through discrimination. The recovery of a person with mental illness means to get and keep hope, to understand their own possibilities and impossibilities, active living, to be autonomous, to have a social identity and to give meaning and purpose of our own lives. The care system, recovery-oriented, provides help and support to people with mental disorders in his/her recovery, which contributes to reduction of self-stigma, to the elimination of stigmatizing attitudes and beliefs in mental health services which consequently may have a positive reflection in reducing the stigma of mental illness in the community. It is important to look at the stigma and recovery from the perspective of individual experience of each person with a mental illness in the process of recovery. A support to the recovery concept and the development of a recovery-oriented system of care should be one of the key segments of any strategy to combat the stigma of mental illness. Also, the cultural and the social stigma aspects of stigma would be taken into account in the developing of the recovery concept and on the recovery-oriented care system.

    Full Text Available Primary, secondary and tertiary alcohols can be easily distinguished due to their reactivity towards tribromoisocyanuric acid (TBCA. The test is performed by adding TBCA to the alcohol in a test tube heated in a boiling water bath. Orange color develops in the tube containing the primary alcohol, light yellow is observed in the tube containing the secondary alcohol while the tertiary alcohol results in a colorless mixture.

  17. Determining factors of youth unemployment in Greece with emphasis on tertiary education graduates


    Theodore Mitrakos; Panos Tsakloglou; Ioannis Cholezas


    Unemployment rates for young individuals are particularly high in Greece and an important fraction of the young unemployed are tertiary education graduates. The results of this study imply that the problem is the transition from education to the labour market, irrespective of the individual’s age and educational qualifications. By and large, unemployment rates for tertiary education graduates tend to diminish a few years after graduation, while they fall slower and remain higher for persons w...

  19. Positive effects of tertiary centres for amyotrophic lateral sclerosis on outcome and use of hospital facilities. (United States)

    Chiò, A; Bottacchi, E; Buffa, C; Mutani, R; Mora, G


    To evaluate the effects of tertiary centres for amyotrophic lateral sclerosis (ALS) on ALS outcome and the use of hospital facilities. The study was based on the data of an epidemiological, prospective, population-based register on ALS (Piemonte and Valle d'Aosta Register for amyotrophic lateral sclerosis, PARALS). The 221 patients recruited between 1995 and 1996 were prospectively followed up for outcome and use of hospital-based services. In all, 97 patients were followed up by tertiary ALS centres and 124 by general neurological clinics. Patients followed up by tertiary ALS centres were found to be 4 years younger and underwent percutaneous endoscopic gastronomy and non-invasive positive-pressure ventilation more often. Patients followed up by tertiary ALS centres were found to have a considerably longer median survival time (1080 v 775 days), even when stratifying by age, site of onset and respiratory function at diagnosis. In Cox multivariate analysis, attending a tertiary ALS centre was observed to be an independent positive prognostic factor. Moreover, patients attending a tertiary ALS centre were admitted to hospital less often (1.2 v 3.3) and were more frequently admitted for planned interventions. Conversely, patients followed up by general neurological clinics were more frequently admitted for acute events. Also, the hospital stay was considerably shorter for patients attending tertiary ALS centres (5.8 v 12.4 days). Improved survival was seen in patients with ALS attending tertiary ALS centres, independently from all other known prognostic factors, possibly through a better implementation of supportive treatments. Moreover, because of these centres, the hospitalisation rate was markedly reduced, thus offering a cost-effective service to patients with ALS and to the community as a whole.

  20. Tertiary thiols from allylic thiocarbamates by tandem enantioselective [3,3]-sigmatropic rearrangement and stereospecific arylation. (United States)

    Mingat, Gaëlle; MacLellan, Paul; Laars, Marju; Clayden, Jonathan


    The synthesis of tertiary thiols in enantiomerically enriched form is accomplished by lithiation of enantiomerically enriched N-aryl allylic thiocarbamates. Formation of an allyllithium derivative promotes intramolecular N to C aryl migration to the position α to sulfur, generally with good stereospecificity. The substrates may themselves be obtained by Pd-catalyzed enantioselective [3,3]-sigmatropic rearrangement of N-aryl O-allyl thiocarbamates. Solvolysis of the product thiocarbamates yields tertiary thiols, which may be converted to sulfide derivatives.

  3. Recycling and recovery routes of plastic solid waste (PSW): a review. (United States)

    Al-Salem, S M; Lettieri, P; Baeyens, J


    Plastic solid waste (PSW) presents challenges and opportunities to societies regardless of their sustainability awareness and technological advances. In this paper, recent progress in the recycling and recovery of PSW is reviewed. A special emphasis is paid on waste generated from polyolefinic sources, which makes up a great percentage of our daily single-life cycle plastic products. The four routes of PSW treatment are detailed and discussed covering primary (re-extrusion), secondary (mechanical), tertiary (chemical) and quaternary (energy recovery) schemes and technologies. Primary recycling, which involves the re-introduction of clean scrap of single polymer to the extrusion cycle in order to produce products of the similar material, is commonly applied in the processing line itself but rarely applied among recyclers, as recycling materials rarely possess the required quality. The various waste products, consisting of either end-of-life or production (scrap) waste, are the feedstock of secondary techniques, thereby generally reduced in size to a more desirable shape and form, such as pellets, flakes or powders, depending on the source, shape and usability. Tertiary treatment schemes have contributed greatly to the recycling status of PSW in recent years. Advanced thermo-chemical treatment methods cover a wide range of technologies and produce either fuels or petrochemical feedstock. Nowadays, non-catalytic thermal cracking (thermolysis) is receiving renewed attention, due to the fact of added value on a crude oil barrel and its very valuable yielded products. But a fact remains that advanced thermo-chemical recycling of PSW (namely polyolefins) still lacks the proper design and kinetic background to target certain desired products and/or chemicals. Energy recovery was found to be an attainable solution to PSW in general and municipal solid waste (MSW) in particular. The amount of energy produced in kilns and reactors applied in this route is sufficiently

    Suik, H. [Tallinn Technical University, Horizon Pulp and Paper, Tallinn (Estonia)


    The corrosion of heat surfaces and the cracking the drums are the main problems of the recovery boiler. These phenomena have been appeared during long-term operation of boiler `Mitsubishi - 315` erected at 1964. Depth of the crack is depending on the number of shutdowns and on operation time. Corrosion intensity of different heat surfaces is varying depend on the metal temperature and the conditions at place of positioning of tube. The lowest intensity of corrosion is on the bank tubes and the greatest is on the tubes of the second stage superheater and on the tubes at the openings of air ports. (orig.) 5 refs.

  5. Sustainable phosphorus recovery from waste.


    Kleemann, Rosanna


    Phosphorus (P) is an essential non-substitutable nutrient for all living organisms, but it is also a dwindling non-renewable resource. Approximately two-thirds of the world’s supply of phosphate rock is located in China, Morocco, and the USA. Phosphate rock is included in the EU list of ‘critical raw materials’ and is ranked 20th in an index of commodity price volatility. P recovery from waste water can help alleviate reliance on imported phosphate and reduce vulnerability to fluctuating pric...

  9. The Ames Resource Recovery facility (United States)

    Chantland, A. O.

    The diminishing availability of natural gas, the use of high-sulfur coal and the need to dispose of waste material prompted the City of Ames, IA, to build a facility to produce refuse-derived fuel (RDF) and to recover other valuable resources from the city's solid waste. Recovery is through mechanical processes. The fuel is used to fire two types of boilers as a supplement to coal in an electric generating plant. Ferrous metals and miscellaneous materials are also recovered and marketed.

  10. Nutritional Supplements to Enhance Recovery (United States)

    Ziegenfuss, Tim N.; Landis, Jamie; Greenwood, Mike

    The ability to recover from intense exercise often separates good athletes from great ones. In the past, "recovery" often simply included rest, physical modalities (e.g., massage, hydration therapy) and meeting basic nutritional needs for fluid and energy intake. Today, athletes have a number of additional options to help them recover from high intensity training, one of which includes the judicious use of dietary supplements. This chapter briefly reviews nutritional strategies that have a strong theoretical background for enhancing rehydration/electrolyte balance, replenishing energy reserves, minimizing oxidative damage, and stimulating muscle repair.

  11. Alcohol, Athletic Performance and Recovery

    David Cameron-Smith


    Full Text Available Alcohol consumption within elite sport has been continually reported both anecdotally within the media and quantitatively in the literature. The detrimental effects of alcohol on human physiology have been well documented, adversely influencing neural function, metabolism, cardiovascular physiology, thermoregulation and skeletal muscle myopathy. Remarkably, the downstream effects of alcohol consumption on exercise performance and recovery, has received less attention and as such is not well understood. The focus of this review is to identify the acute effects of alcohol on exercise performance and give a brief insight into explanatory factors.

  12. Microwave Plasma Hydrogen Recovery System (United States)

    Atwater, James; Wheeler, Richard, Jr.; Dahl, Roger; Hadley, Neal


    A microwave plasma reactor was developed for the recovery of hydrogen contained within waste methane produced by Carbon Dioxide Reduction Assembly (CRA), which reclaims oxygen from CO2. Since half of the H2 reductant used by the CRA is lost as CH4, the ability to reclaim this valuable resource will simplify supply logistics for longterm manned missions. Microwave plasmas provide an extreme thermal environment within a very small and precisely controlled region of space, resulting in very high energy densities at low overall power, and thus can drive high-temperature reactions using equipment that is smaller, lighter, and less power-consuming than traditional fixed-bed and fluidized-bed catalytic reactors. The high energy density provides an economical means to conduct endothermic reactions that become thermodynamically favorable only at very high temperatures. Microwave plasma methods were developed for the effective recovery of H2 using two primary reaction schemes: (1) methane pyrolysis to H2 and solid-phase carbon, and (2) methane oligomerization to H2 and acetylene. While the carbon problem is substantially reduced using plasma methods, it is not completely eliminated. For this reason, advanced methods were developed to promote CH4 oligomerization, which recovers a maximum of 75 percent of the H2 content of methane in a single reactor pass, and virtually eliminates the carbon problem. These methods were embodied in a prototype H2 recovery system capable of sustained high-efficiency operation. NASA can incorporate the innovation into flight hardware systems for deployment in support of future long-duration exploration objectives such as a Space Station retrofit, Lunar outpost, Mars transit, or Mars base. The primary application will be for the recovery of hydrogen lost in the Sabatier process for CO2 reduction to produce water in Exploration Life Support systems. Secondarily, this process may also be used in conjunction with a Sabatier reactor employed to

  13. Remote Sensing Tertiary Education Meets High Intensity Interval Training (United States)

    Joyce, K. E.; White, B.


    Enduring a traditional lecture is the tertiary education equivalent of a long, slow, jog. There are certainly some educational benefits if the student is able to maintain concentration, but they are just as likely to get caught napping and fall off the back end of the treadmill. Alternatively, a pre-choreographed interactive workshop style class requires students to continually engage with the materials. Appropriately timed breaks or intervals allow students to recover briefly before being increasingly challenged throughout the class. Using an introductory remote sensing class at Charles Darwin University, this case study presents a transition from the traditional stand and deliver style lecture to an active student-led learning experience. The class is taught at undergraduate and postgraduate levels, with both on-campus as well as online distance learning students. Based on the concept that active engagement in learning materials promotes 'stickiness' of subject matter, the remote sensing class was re-designed to encourage an active style of learning. Critically, class content was reviewed to identify the key learning outcomes for the students. This resulted in a necessary sacrifice of topic range for depth of understanding. Graduates of the class reported high levels of enthusiasm for the materials, and the style in which the class was taught. This paper details a number of techniques that were used to engage students in active and problem based learning throughout the semester. It suggests a number of freely available tools that academics in remote sensing and related fields can readily incorporate into their teaching portfolios. Moreover, it shows how simple it can be to provide a far more enjoyable and effective learning experience for students than the one dimensional lecture.

  14. Biometric Secured Result Processing Software For Nigerian Tertiary Institutions

    Oladipo Oluwasegun


    Full Text Available Abstract One of the challenges facing result processing in Nigerian tertiary institutions is the problem of insecurity. Untraceable changes are made to students result and this result to various disasters such as innocent people losing their jobs since their innocence cannot be proven. Biometric based systems operate on behavioral and physiological biometric data to identify a person and grant required access to a user. Physiological characteristics such as fingerprint remains unchanged throughout an individuals life time and thus it can serve as a viable means of identifying and authenticating users who are to access a system. In this study fingerprint biometric based result processing software is developed to ensure that users are well authenticated and are made to see only what they are pre-configured to see and work with. The fingerprint authentication system was developed using visual Staff fingerprints were enrolled into the system to form a biometric template which the system validates against at every login attempt on the result processing software. The digital personal one touch ID sdk and other libraries were used in developing the authentication system. The result processing software also ensures that all write transactions to the database are confirmed and identified by forcing another biometric authentication at the point of making a write request to the web server and associated database. This ensures that the exact person initiating the transaction was the same user who logged in to the application. The users identified at login and various confirmation milestones set for write transactions are logged into a table for future reference and audit trail. Conclusively the developed system has helped to eradicate the problem of user impersonation by ensuring only authorized users are made to access the software and in-turn participate in result processing activities.

    Patryn, Eliza K; Vrijman, Violette; Nieuwendaal, Carla P; van der Meulen, Ivanka J E; Mourits, Maarten P; Lapid-Gortzak, Ruth


    To review the spectrum of disease, symptomatology, and management offered to patients referred for a second opinion after refractive surgery. A prospective cohort study was done on all patients referred from October 1, 2006, to September 30, 2011, to a tertiary eye clinic after refractive surgery of any kind (ie, corneal laser surgery, conductive keratoplasty, radial keratotomy, phakic implants, refractive lens exchanges, or any combination thereof). Data analysis was performed on all demographic and clinical aspects of this cohort, including the initial complaint, type of referral, number of complaints, procedure previously performed, diagnosis at our center, type of advice given, and rate and type of surgical intervention. One hundred thirty-one eyes (69 patients) were included. Corneal refractive surgery was performed in 82% (108 eyes), and 11% (14 eyes) were seen after phakic intraocular lens (PIOL) implantation and 7% (9 eyes) after refractive lens exchange. The most common diagnoses were tear film dysfunction (30 eyes, 23%), residual refractive error (25 eyes, 19%), and cataract (20 eyes, 15%). Most patients (42 patients, 61%) were treated conservatively. In 27 patients (39%), 36 eyes (28%) were managed surgically. Severe visual loss was seen in 1 eye. No major problems were found in most second opinions after refractive surgery referral. Dry eyes, small residual refractive error, or higher-order aberrations were the most common complaints. Surgical intervention was needed in 36 eyes (28%), almost half of which were cataract extractions. Severe visual loss was seen in 1 eye with a PIOL. There was no incidence of severe visual loss in keratorefractive and refractive lens exchange procedures. Copyright 2014, SLACK Incorporated.

    Full Text Available Objective: to analyze the epidemiology, clinical features and survival rate of patients undergoing orbital exenteration (OE in a tertiary referral hospital. Methods : we conducted a retrospective study of all patients undergoing OE at the Hospital das Clínicas, FMUSP between January 2007 and December 2012. We collected data records related to gender, age, origin, length of stay, duration of the disease, other treatments related to the disease, number of procedures outside of the face related to the disease, follow-up and histological diagnosis. Results : we treated 37 patients in the study period. The average survival in one year was 70%, in two years, 66.1%, and 58.3% in three years. There was no significant difference in the one-year survival related to histological diagnosis (p=0.15, days of hospitalization (p=0.17, gender (p=0.43, origin (p=0.78, disease duration (p=0.27 or the number of operations for the tumor (p=0.31. Mortality was higher in elderly patients (p=0.02. The average years of life lost was 33.9 in patients under 60 years, 14.7 in patients in the 61-80 years range and 11.3 in patients over 80 years. Conclusion : the present series of cases is significant in terms of prevalence of orbital exenteration; on the other hand, it shows one of the lowest survival rates in the literature. This suggests an urgent need for improved health care conditions to prevent deforming, radical resections.

  17. Meconium aspiration syndrome - the experience of a tertiary center. (United States)

    Espinheira, M C; Grilo, M; Rocha, G; Guedes, B; Guimarães, H


    Approximately 5 % of infants born with a meconium-stained amniotic fluid (MSAF) develop meconium aspiration syndrome (MAS). The aims of this study were to analyse demographic data, morbidity and mortality associated with MAS and to identify possible risk factors. Retrospective chart review of newborns with MAS delivered at a tertiary centre from January 1st, 1997 to December 31st, 2008. MAS was responsible for 1.4 % of all Neonatal Intensive Care Unit (NICU) admissions, with a trend towards a decreasing incidence during the study duration, especially in the cases of thin meconium. Seventy two newborns were analysed during the study period: 55.6 % (n = 40) were of the female gender, 62.5 % were delivered by caesarean section, 93 % had > 36 weeks of gestational age and 91.2 % had a birth weight over 2500g. Sixty-nine percent had an Apgar score bradicardia was present in 26.4 % of the newborns and tachycardia in 1.4 %. The presence of meconium was associated with severe asphyxia and carried a bad prognosis with an increased risk of developing hypoxia (58.3 %), need of mechanical ventilatory support (43.1 %), respiratory and/or metabolic acidosis (30.6 %), pulmonary hypertension (11.1 %) and hypoxic ischemic encephalopathy (29.2 %). The mortality rate was 2.8 %. Thick meconium was associated with higher morbidity and mortality rates. The number of admissions for MAS has been decreasing mostly because of a lower admission rate due to thin meconium; the number of cases with thick meconium has remained constant throughout the years. An Apgar score < 7 at 1 minute and signs of foetal distress during labour were associated with MAS. The MAS related morbidity remains significant.

  18. Mainstreaming of Climate Change into the Ghanaian Tertiary Educational System (United States)

    Nyarko, B. K.


    The impact of Climate Change has a far-reaching implication for economies and people living in the fragile Regions of Africa analysts project that by 2020, between 75 million and 250 million people will be exposed various forms of Climate Change Stresses. Education as a key strategy identified under Agenda 21 has been incorporated into the efforts of various educational institutions as a means of mitigating climate change and enhancing sustainability. Climate Change education offers many opportunities and benefits for educators, researchers, learners, and for wider society, but there are also many challenges, which can hinder the successful mainstreaming of climate change education. The study aims at understanding barriers for Climate Change Education in selected tertiary institutions in Ghana. The study was conducted among Geoscience Departments of the 7 main public universities of Ghana. The transcript analysis identified issues that hinders the mainstreaming of Climate Change, these includes existing levels of knowledge and understanding of the concept of climate change, appreciating the threshold concepts, ineffective teaching of Climate Change and some Departments are slow in embracing Climate Change as a discipline. Hence to develop strategies to mainstream climate change education it is important to recognise that increasing the efficiency and delivery of Climate Change education requires greater attention and coordination of activities and updating the educators knowledge and skill's. Various Ministries should be challenged to develop and integrate climate change into education policies. In the design of curriculum, there is a need to integrate Climate Change Education into curricula without compromising already overstretched programmes of study. There is a need to encourage and enhance innovative teaching approaches such as Problem-based learning (PBL) is an approach that challenges students to learn through engagement in a real problem.

    M S Maputle


    Full Text Available The purpose of the study was to explore and describe experiences of mothers during childbirth in a tertiary hospital in the Limpopo Province. This was achieved through a qualitative research study which was exploratory, descriptive, contextual and inductive in nature. A sample of 24 mothers participated in this study. Data obtained from unstructured in-depth interviews were analysed according to the protocol by Tesch (1990, cited in Cresswell, 1994:155. Five themes were identified, namely mutual participation and responsibility sharing, dependency and decision-making; information sharing and empowering autonomy and informed choices; open communication and listening; accommodative/non-accommodative midwifery actions; and maximising human and material infrastructure. The themes indicated experiences that foster or promote dependency on midwifery care. Guidelines on how to transform this dependency into a mother-centered care approach during childbirth are provided.

  20. Near total parathyroidectomy is effective therapy for tertiary hyperparathyroidism. (United States)

    Dewberry, Lindel Krige; Weber, Collin; Sharma, Jyotirmay


    Tertiary hyperparathyroidism (3°HPT) is defined as persistent hyperparathyroidism with hypercalcemia after renal transplantation. Near total parathyroidectomy (NTPTX) is the current standard for surgical intervention. The purpose of this study was to identify outcomes of NTPTX. A retrospective review was conducted of surgeries performed between 1994 and 2013. NTPTX resulted in resolution of 96.9 per cent of patients' hypercalcemia at a median follow-up of three years (interquartile range [IQR], 1 to 8). However, 3.1 per cent of patients remained hypercalcemic with a mean calcium of 10.5 ± 0.2 mg/dL. A total of 78.4 per cent of patients had parathyroid hormone (PTH) levels below 250 pg/mL at a median follow-up of two years (IQR, 2 to 8). The remaining 21.6 per cent had a median PTH of 535 (IQR, 345 to 857). PTH levels dropped from a median of 745 (IQR, 285.75 to 1594.25) pg/mL to 97 (IQR, 60 to 285) pg/mL one month post-NTPTX (P < 0.01). The most frequent complication was transient hypocalcemia in 27.1 per cent of patients, but no patients became permanently hypocalcemic. In the 1-month postoperative period, only one patient had a cardiac complication, and there was 0 per cent all-cause mortality. Glomerular filtration rate fell from 57.9 ± 28.3 mL/min pre-NTPTX to 53.2 ± 27.5 mL/min at 1-year post-NTPTX (P < 0.01). NTPTX effectively treats hypercalcemia in 3°HPT. However, PTH remains elevated (greater than 250) in 21.6 per cent of patients.

  1. [Eosinophilic esophagitis--the experience in a tertiary pediatric center]. (United States)

    Guz-Mark, Anat; Zevit, Noam; Rosenbach, Yoram; Morgenstern, Sara; Reznik, Dana; Davidson, Keren; Shamir, Raanan; Livni, Gilat


    Eosinophilic esophagitis (EoE) is an inflammatory disorder with increasing prevalence. It typically presents with swallowing difficulties, heartburn or dyspepsia, and in toddlers, failure to thrive. EoE is characterized by eosinophilic infiltrates of the esophageal mucosa, and endoscopies with tissue diagnosis are mandatory. Hypersensitivity has been implicated in the pathogenesis, therefore, most treatment options include steroids and allergen avoidance. To summarize a tertiary pediatric clinic's experience with EoE in children and adolescents, describe the spectrum of clinical presentations and treatment options, and raise awareness of this disorder among medical personnel. A retrospective, descriptive study of patients diagnosed with EoE at our institute over the past 5 years. Demographic details, presenting symptoms, laboratory studies, endoscopic and pathologic findings were analyzed. Information regarding medical and nutritional therapies and response to treatment were summarized. Fifteen cases of EoE in children and adolescents are described. Average age at diagnosis was 9 years (range 0.7-161. The most common complaint was dysphagia (60%e. The majority demonstrated food allergies 19/121. Most of the patients were treated with topical ingested steroids, while others had either elemental formula or allergen elimination. Favorable responses were seen in most patients treated with steroids (8/11). Long-term results of nutritional therapy are insufficient to draw conclusions on its efficacy. EoE causes major eating difficulties and affects quality of life in children, sometimes accompanied by failure to thrive. There is a clear association with food allergies, and positive responses to steroids are common. A high index of suspicion and referral to a gastroenterologist for definite diagnosis are required. Combining medical with nutritional treatment seems promising but further studies regarding the long-term outcome are needed.

  2. Multiphoton ionization-fragmentation patterns of tertiary amines (United States)

    Parker, D. H.; Bernstein, R. B.; Lichtin, D. A.


    Multiphoton ionization (MPI)-fragmentation patterns are reported for a series of normal and caged tertiary amines. Ionization is enhanced by two-photon resonance with the 3s and 3p Rydberg states of trimethylamine, triethylamine, and the caged amines quinuclidine and triethylenediamine. Over the wavelength region λ = 400-530 nm, N(CH3)3 ionizes to the parent ion (P) and fragments only by the loss of a H atom to yield the P-H daughter ion; N(C2H5)3 ionizes to its parent ion and fragments by the loss of a methyl to form the P-CH3 ion. The branching ratio of daughter to parent ions is found to be essentially independent of laser intensity but strongly dependent on laser wavelength. The caged amines quinuclidine [N(C2H4)3CH, or ABCO] and triethylenediamine [N(C2H4)3N, or DABCO] fragment extensively over this λ range in a manner dependent on both laser wavelength and intensity. The extent of daughter ion formation in N(CH3)3 and N(C2H5)3 can be understood by consideration of the wavelength regions in which the total available energy from the initial three- or four-photon ionization event exceeds the appearance potential of the given daughter ion. For the caged amines direct observation of this mechanism is masked by fragmentation due to sequential absorption of photons (during the ˜5 ns pulse duration) by the parent and/or daughter ions. The present results show that even for molecules with broad, unstructured UV absorption and MPI spectra such as N(CH3)3 and N(C2H5)3, considerable information on photon-molecule and photon-ion interactions can still be gained by the MPI mass spectrometry technique.

    Introduction: Vaginal discharge is one of the common reasons for gynecological consultation. Many of the causes of vaginitis have a disturbed vaginal microbial ecosystem associated with them. Effective treatment of vaginal discharge requires that the etiologic diagnosis be established and identifying the same offers a precious input to syndromic management and provides an additional strategy for human immunodeficiency virus prevention. The present study was thus carried out to determine the various causes of vaginal discharge in a tertiary care setting. Materials and Methods: A total of 400 women presenting with vaginal discharge of age between 20 and 50 years, irrespective of marital status were included in this study and women who had used antibiotics or vaginal medication in the previous 14 days and pregnant women were excluded. Results: Of the 400 women with vaginal discharge studied, a diagnosis was established in 303 women. Infectious causes of vaginal discharge were observed in 207 (51.75%) women. Among them, bacterial vaginosis was the most common cause seen in 105 (26.25%) women. The other infections observed were candidiasis alone (61, 15.25%), trichomoniasis alone (12, 3%), mixed infections (22, 5.5%) and mucopurulent cervicitis (7 of the 130 cases looked for, 8.46%). Among the non-infectious causes, 72 (18%) women had physiological vaginal discharge and 13 (3.3%) women had cervical in situ cancers/carcinoma cervix. Conclusion: The pattern of infectious causes of vaginal discharge observed in our study was comparable with the other studies in India. Our study emphasizes the need for including Papanicolaou smear in the algorithm for evaluation of vaginal discharge, as it helps establish the etiology of vaginal discharge reliably and provides a valuable opportunity to screen for cervical malignancies.

    The knowledge of the distribution and pattern of salivary gland tumors in the tertiary care center can provide overview of the disease pattern in the region. It also helps in planning the strategies to treat the disease and launch the awareness program in the community to this largely curable disease. A retrospective observational study of all the salivary gland tumors treated in the department of Otolaryngology, B. P. Koirala Institute of Health Sciences during April 2004 to March 2009 was done. Age, sex, presenting features, radiological findings, histopathological type of the tumor and type of surgery were recorded and descriptive analysis was done to calculate frequencies, percentage and their relations. Out of total 51 cases, 81% (n=41) were benign and 19% (n=10) malignant tumors. Male to female ratio was 1:2.1. Mean age for benign and malignant tumors were 32.3 and 46.5 years respectively. Parotid tumor outnumbered all other sites comprising 69%, followed by submandiibular 18% and minor glands 13%. Pleomorphic adenoma was the commonest tumor (76%) of all primary salivary gland tumors. Benign to malignant tumor ratio of parotid, submandibular and minor glands were 6:1, 3.5:1 and 1.3:1 respectively. Adenoid cystic carcinoma (40%) and mucoepidermoid carcinoma (30%) were commonest malignant tumors. The principal site for salivary gland tumors in eastern Nepal population was the parotid and the pleomorphic adenoma outnumbered all other tumors. Most of the cases in both benign and malignant group presented with painless lump often misleading the gravity of disease.

    Full Text Available Language assessment can be a valuable tool for providing information regarding language teaching. Given the importance of assessment that has undergone much change, there are important issues that warrant investigation, particularly those related to language instructors. Understanding the assessment beliefs of ESL instructors, especially at the tertiary level, is important since it can help improve the quality of assessment practices as well. Therefore, this study investigated English language instructors’ assessment beliefs in the Malaysian context. This study adopted a cross-sectional research design. The survey method was utilized to collect data from six Malaysian universities using a purposive sampling strategy. English language instructors (n=83 were selected via purposive sampling for the study. Findings of the study revealed that English language instructors believed that the purpose of assessment was to improve teaching and learning. Regarding the assessment beliefs that are related to the assessment purposes, analyses of data showed that the items that received the highest percentage of agreement were diagnosing strength and weaknesses in students, providing information about students’ progress and providing feedback to students as they learn, respectively. Although they reported using both formal and informal assessment of their students’ work, English language instructors relied heavily on paper and pencil assessment while giving more weightage on formative assessment. The majority of English language instructors reported employing marking schemes for the courses they taught, carrying out sample marking and providing feedback. Finally, English language instructors reported using different types of assessments for every language skill taught in their language unit/center. The findings highlight the fact that English instructors should be more empowered in their role as the assessors of students. Their knowledge about what, how

    Bernasconi, A; Azancot, A; Simpson, J M; Jones, A; Sharland, G K


    Objective: To evaluate the incidence of fetal dextrocardia, associated cardiac and extracardiac malformations, and outcome. Design: Retrospective echocardiographic study. Setting: Two tertiary centres for fetal cardiology. Patients: 81 consecutive fetuses with a fetal dextrocardia presenting at Guy’s Hospital, London, between 1983 and 2003 and at Hôpital Robert Debré, Paris, between 1988 and 2003. Fetal dextrocardia was defined as a condition in which the major axis of the heart points to the right. Results: The incidence was 0.22%. There were 38 fetuses (47%) with situs solitus (SS), 24 (30%) with situs ambiguus (SA), and 19 (23%) with situs inversus (SI). Structural cardiac malformations were found in 25 cases (66%) of SS, 23 cases (96%) of SA, and 12 cases (63%) of SI. Extracardiac malformations were identified in 12 cases (31%) of SS, in five cases (21%) of SA, and in two cases (10%) of SI. Of the 81 cases of fetal dextrocardia, there were 27 interrupted pregnancies (15 of 24 SA, 10 of 38 SS, and 2 of 19 SI), six intrauterine deaths (3 of 38 SS, 2 of 24 SA, and 1 of 19 SI), and five neonatal deaths (3 of 24 SA, 1 of 19 SI, and 1 of 38 SS). There were 43 survivors (24 of 38 SS, 15 of 19 SI, and 4 of 24 SA). Conclusion: The majority of fetuses with dextrocardia referred for fetal echocardiography have associated congenital heart disease. There is a broad spectrum of cardiac malformation and the incidence varies according to the atrial situs. Fetal echocardiography enables detection of complex congenital heart disease so that parents can be appropriately counselled. PMID:16287744

    Adhikari, Chaitanya Raj; Parajuli, Durga; Kawakita, Hidetaka; Inoue, Katsutoshi; Ohto, Keisuke; Harada, Hiroyuki


    Waste newsprint paper was modified with dimethylamine (DMA) to obtain a tertiary amine type adsorption gel called DMA-paper gel. This new derivative was investigated for adsorption, from hydrochloric acid medium, of gold, palladium, and platinum as well as some base metals. The gel exhibited selectivity only for precious metals with a remarkably high capacity for Au(III), i.e., 4.6 mol/kg dry gel and comparable capacities, i.e., 2.1 and 0.9 mol/kg for Pd(II) and Pt(IV), respectively. Also, Au(III) was reduced to the elemental form during adsorption. Furthermore, column adsorption and subsequent elution of the adsorbed metal ions by acidic thiourea revealed encouraging recoveries (approximately 90%), thus enhancing the scope of the gel for effective preconcentration, separation, and recovery of precious metals. The effectiveness of recovery of precious metals from real industrial liquor was also tested, and it showed highly encouraging results with respect to the stability of the gel in the harsh medium, and selectivity for the targeted metal ions in the presence of excess of other metal ions.

    Root, Jeremy M; Zuckerbraun, Noel S; Wang, Li; Winger, Daniel G; Brent, David; Kontos, Anthony; Hickey, Robert W


    To determine the association between a history of somatization and prolonged concussion symptoms, including sex differences in recovery. A prospective cohort study of 10- to 18-year-olds with an acute concussion was conducted from July 2014 to April 2015 at a tertiary care pediatric emergency department. One hundred twenty subjects completed the validated Children's Somatization Inventory (CSI) for pre-injury somatization assessment and Postconcussion Symptoms Scale (PCSS) at diagnosis. PCSS was re-assessed by phone at 2 and 4 weeks. CSI was assessed in quartiles with a generalized estimating equation model to determine relationship of CSI to PCSS over time. The median age of our study participants was 13.8 years (IQR 11.5, 15.8), 60% male, with separate analyses for each sex. Our model showed a positive interaction between total CSI score, PCSS and time from concussion for females P somatization had higher PCSS than the other 3 CSI quartiles at each time point (B -26.7 to -41.1, P values somatization had higher concussion symptom scores over time. Females in the highest somatization quartile had prolonged concussion recovery with persistently high symptom scores at 4 weeks. Somatization may contribute to sex differences in recovery, and assessment at the time of concussion may help guide management and target therapy. Copyright © 2016 Elsevier Inc. All rights reserved.

Catolica do Rio de Janeiro, RJ (Brazil); Naccache, Monica F. [Pontificia Univ. Catolica do Rio de Janeiro, RJ (Brazil). Dept. de Engenharia Mecanica


    In crude oil extraction, water can be injected into the well (secondary oil recovery). The amount of the oil extracted decrease after some operation time. In order to improve the oil recovery, polymer flooding would subsequently be used (tertiary oil recovery). The aim of this work was to study the rheological behavior of polyacrylamide, xanthan gum, guar gum and their blends in seawater solutions, and the rheology of a crude oil. Dynamic measurements of the pure polymers (1000 ppm) and blends (2000 ppm) exhibited G' values lower than G'' in low frequencies, and inversion of G' and G'' curves in frequencies between 20 and 30 rad/s. The xanthan gum presented the greatest values of G' when compared to the other polymers, which means that its structure is more rigid. The oil showed G' values lower than G'' values in low and high frequencies of oscillation. Steady measurements revealed pseudoplastic behavior for polymers and Newtonian behavior for the oil. In shear rates around 10 s{sup -1}, polyacrylamide/xanthan blend would be the most appropriate for the extraction of the oil presented. (author)

  11. Application of Nanoparticles in Enhanced Oil Recovery: A Critical Review of Recent Progress

    Directory of Open Access Journals (Sweden)

    Xiaofei Sun


    Full Text Available The injected fluids in secondary processes supplement the natural energy present in the reservoir to displace oil. The recovery efficiency mainly depends on the mechanism of pressure maintenance. However, the injected fluids in tertiary or enhanced oil recovery (EOR processes interact with the reservoir rock/oil system. Thus, EOR techniques are receiving substantial attention worldwide as the available oil resources are declining. However, some challenges, such as low sweep efficiency, high costs and potential formation damage, still hinder the further application of these EOR technologies. Current studies on nanoparticles are seen as potential solutions to most of the challenges associated with these traditional EOR techniques. This paper provides an overview of the latest studies about the use of nanoparticles to enhance oil recovery and paves the way for researchers who are interested in the integration of these progresses. The first part of this paper addresses studies about the major EOR mechanisms of nanoparticles used in the forms of nanofluids, nanoemulsions and nanocatalysts, including disjoining pressure, viscosity increase of injection fluids, preventing asphaltene precipitation, wettability alteration and interfacial tension reduction. This part is followed by a review of the most important research regarding various novel nano-assisted EOR methods where nanoparticles are used to target various existing thermal, chemical and gas methods. Finally, this review identifies the challenges and opportunities for future study regarding application of nanoparticles in EOR processes.

  12. Factors Associated With Recovery from Anorexia Nervosa (United States)

Blake; Kaye, Walter H.; Bulik, Cynthia M.


    Previous studies of prognostic factors of anorexia nervosa (AN) course and recovery have followed clinical populations after treatment discharge. This retrospective study examined the association between prognostic factors—eating disorder features, personality traits, and psychiatric comorbidity—and likelihood of recovery in a large sample of women with AN participating in a multi-site genetic study. The study included 680 women with AN. Recovery was defined as the offset of AN symptoms if the participant experienced at least one year without any eating disorder symptoms of low weight, dieting, binge eating, and inappropriate compensatory behaviors. Participants completed a structured interview about eating disorders features, psychiatric comorbidity, and self-report measures of personality. Survival analysis was applied to model time to recovery from AN. Cox regression models were used to fit associations between predictors and the probability of recovery. In the final model, likelihood of recovery was significantly predicted by the following prognostic factors: vomiting, impulsivity, and trait anxiety. Self-induced vomiting and greater trait anxiety were negative prognostic factors and predicted lower likelihood of recovery. Greater impulsivity was a positive prognostic factor and predicted greater likelihood of recovery. There was a significant interaction between impulsivity and time; the association between impulsivity and likelihood of recovery decreased as duration of AN increased. The anxiolytic function of some AN behaviors may impede recovery for individuals with greater trait anxiety. PMID:23535032

  13. Towards a definition of recovery of function. (United States)

    Murray, Marion; Fischer, Itzhak; Smeraski, Cynthia; Tessler, Alan; Giszter, Simon


    In this review we consider recovery of function after spinal cord injury, and, in particular, recovery improved following intraspinal cellular transplants. Some recovery occurs spontaneously and this can be especially dramatic in neonates, supporting the notion that developing and adult spinal cord respond differently to injury. Recovery can be improved in both neonates and adults by appropriate cellular transplants into the injury site. We describe several functional tests used in animals with spinal lesions and transplants. We compare the effects of transplants of fetal tissue and genetically modified fibroblasts into neonatal and adult injury sites on recovery of motor and sensorimotor function. Fetal tissue transplants support greater recovery and elicit more regeneration in neonates than in adults. Transplants of fibroblasts modified to produce neurotrophic factors however support both recovery and axonal growth even in adults. The contribution of the transplant to recovery is shown by the loss of function that follows a second lesion just rostral to the original lesion/transplant site. The effect of the re-lesion indicates that the recovery is mediated by the presence of the transplant but the way in which transplants act to promote recovery may include a number of mechanisms, including regeneration and sprouting, neuroprotection, and modifications of organization of spared CNS structures.

    This article highlights the research presentations at the satellite symposium on "Brain Pathways to Recovery from Alcohol Dependence" held at the 2013 Society for Neuroscience Annual Meeting. The purpose of this symposium was to provide an up to date overview of research efforts focusing on understanding brain mechanisms that contribute to recovery from alcohol dependence. A panel of scientists from the alcohol and addiction research field presented their insights and perspectives on brain mechanisms that may underlie both recovery and lack of recovery from alcohol dependence. The four sessions of the symposium encompassed multilevel studies exploring mechanisms underlying relapse and craving associated with sustained alcohol abstinence, cognitive function deficit and recovery, and translational studies on preventing relapse and promoting recovery. Gaps in our knowledge and research opportunities were also discussed. Published by Elsevier Inc.

  16. Saturation Recovery EPR and Nitroxide Spin Labeling for Exploring Structure and Dynamics in Proteins. (United States)

    Yang, Zhongyu; Bridges, Michael; Lerch, Michael T; Altenbach, Christian; Hubbell, Wayne L


    Experimental techniques capable of determining the structure and dynamics of proteins are continuously being developed in order to understand protein function. Among existing methods, site-directed spin labeling in combination with saturation recovery (SR) electron paramagnetic resonance spectroscopy contributes uniquely to the determination of secondary and tertiary protein structure under physiological conditions, independent of molecular weight and complexity. In addition, SR of spin labeled proteins was recently demonstrated to be sensitive to conformational exchange events with characteristic lifetimes on the order of μs, a time domain that presents a significant challenge to other spectroscopic techniques. In this chapter, we present the theoretical background necessary to understand the capabilities of SR as applied to spin labeled proteins, the instrumental requirements, and practical experimental considerations necessary to obtain interpretable data, and the use of SR to obtain information on protein: (1) secondary structure via solvent accessibility measurements, (2) tertiary structure using interspin distance measurements, and (3) conformational exchange. © 2015 Elsevier Inc.

  17. Enzymes for Enhanced Oil Recovery (EOR)


    Nasiri, Hamidreza


    Primary oil recovery by reservoir pressure depletion and secondary oil recovery by waterflooding usually result in poor displacement efficiency. As a consequence there is always some trapped oil remaining in oil reservoirs. Oil entrapment is a result of complex interactions between viscous, gravity and capillary forces. Improving recovery from hydrocarbon fields typically involves altering the relative importance of the viscous and capillary forces. The potential of many EOR me...

  20. Technologies and countermeasures for gas recovery enhancement


    Ping, Guo; Shasha, Jing; Caizhen, Peng


    Since 2000, China has been ranked as one of the top countries in gas production. Nevertheless, the domestic gas production can hardly satisfy the need of national economic development. Besides, an increasing number of gas fields have come to the middle or late development stages, and most gas reservoirs have low recovery efficiency due to the low permeability and water drive nature. Therefore, gas recovery enhancement has become an urgent issue. At present, the oil recovery enhancement is wel...

  1. Glaucoma Blindness at a Tertiary Eye Care Center. (United States)

    Stone, Jordan S; Muir, Kelly W; Stinnett, Sandra S; Rosdahl, Jullia A


    Glaucoma is an important cause of irreversible blindness. This study describes the characteristics of a large, diverse group of glaucoma patients and evaluates associations between demographic and clinical characteristics and blindness. Data were gathered via retrospective chart review of patients (N = 1,454) who were seen between July 2007 and July 2010 by glaucoma service providers at Duke Eye Center. Visual acuity and visual field criteria were used to determine whether patients met the criteria for legal blindness. Descriptive and comparative statistical analyses were performed on the glaucoma patients who were not blind (n = 1,258) and those who were blind (n = 196). A subgroup analysis of only those patients with primary open-angle glaucoma was also performed. In this tertiary care population, 13% (n = 196) of glaucoma patients met criteria for legal blindness, nearly one-half of whom (n = 94) were blind from glaucoma, and another one-third of whom (n = 69) had glaucoma-related blindness. The most common glaucoma diagnosis at all levels of vision was primary open-angle glaucoma. A larger proportion of black patients compared with white patients demonstrated vision loss; the odds ratio (OR) for blindness was 2.25 (95% CI, 1.6-3.2) for black patients compared with white patients. The use of systemic antihypertensive medications was higher among patients who were blind compared with patients who were not blind (OR = 2.1; 95% CI, 1.4-3.1). A subgroup analysis including only patients with primary open-angle glaucoma showed similar results for both black race and use of systemic antihypertensive medications. The relationship between use of systemic antihypertensive medications and blindness was not different between black patients and white patients (interaction P = .268). Data were based on chart review, and associations may be confounded by unmeasured factors. Treated systemic hypertension may be correlated with blindness, and the cause cannot be explained solely

  2. What determines nutritional recovery in malnourished children after correction of congenital heart defects? (United States)

    Vaidyanathan, Balu; Radhakrishnan, Reshma; Sarala, Deepa Aravindakshan; Sundaram, Karimassery Ramaiyar; Kumar, Raman Krishna


    Malnutrition is common in children with congenital heart disease (CHD), especially in developing countries. To examine the impact of corrective intervention on the nutritional status of children with CHD and identify factors associated with suboptimal recovery. Consecutive patients with CHD in a tertiary center in South India were evaluated for nutritional status before and 2 years after corrective intervention. Anthropometry was performed at presentation and every 6 months for 2 years, and z scores were compared. Malnutrition was defined as a weight-for-age, height-for-age, and weight/height z score nutritional status at presentation, and height of parents and not with type of cardiac lesion, dietary intake, or socioeconomic factors. This study from South India demonstrates severe malnutrition in over half of the patients with CHD and is not always reversed by corrective surgery or intervention. Persistent malnutrition after corrective intervention is predicted by nutritional status at presentation, birth weight, and parental anthropometry.

    Raeburn, Toby; Hungerford, Catherine; Sayers, Jan; Escott, Phil; Lopez, Violeta; Cleary, Michelle


    Recovery-oriented mental health services promote the principles of recovery, such as hope and optimism, and are characterized by a personalized approach to developing consumer self-determination. Nurse leaders are increasingly developing such services as social enterprises, but there is limited research on the leadership of these programs. Leading a recovery-oriented mental health nurse social enterprise requires visionary leadership, collaboration with consumers and local health providers, financial viability, and commitment to recovery-focused practice. This article describes the framework of an Australian mental health nursing social enterprise, including the service attributes and leadership lessons that have been learned from developing program sustainability.

    As a result of the 1987 Montreal Protocol and its amendments, the atmospheric loading of anthropogenic ozone-depleting substances is decreasing. Accordingly, the stratospheric ozone layer is expected to recover. However, short data records and atmospheric variability confound the search for early signs of recovery, and climate change is masking ozone recovery from ozone-depleting substances in some regions and will increasingly affect the extent of recovery. Here we discuss the nature and timescales of ozone recovery, and explore the extent to which it can be currently detected in different atmospheric regions.

  9. Rapid Recovery of Damaged Ecosystems (United States)

    Jones, Holly P.; Schmitz, Oswald J.


    Background Recent reports on the state of the global environment provide evidence that humankind is inflicting great damage to the very ecosystems that support human livelihoods. The reports further predict that ecosystems will take centuries to recover from damages if they recover at all. Accordingly, there is despair that we are passing on a legacy of irreparable damage to future generations which is entirely inconsistent with principles of sustainability. Methodology/Principal Findings We tested the prediction of irreparable harm using a synthesis of recovery times compiled from 240 independent studies reported in the scientific literature. We provide startling evidence that most ecosystems globally can, given human will, recover from very major perturbations on timescales of decades to half-centuries. Significance/Conclusions Accordingly, we find much hope that humankind can transition to more sustainable use of ecosystems. PMID:19471645

  12. Aerobic microbial enhanced oil recovery

    Energy Technology Data Exchange (ETDEWEB)

    Torsvik, T. [Univ. of Bergen (Norway); Gilje, E.; Sunde, E.


    In aerobic MEOR, the ability of oil-degrading bacteria to mobilize oil is used to increase oil recovery. In this process, oxygen and mineral nutrients are injected into the oil reservoir in order to stimulate growth of aerobic oil-degrading bacteria in the reservoir. Experiments carried out in a model sandstone with stock tank oil and bacteria isolated from offshore wells showed that residual oil saturation was lowered from 27% to 3%. The process was time dependent, not pore volume dependent. During MEOR flooding, the relative permeability of water was lowered. Oxygen and active bacteria were needed for the process to take place. Maximum efficiency was reached at low oxygen concentrations, approximately 1 mg O{sub 2}/liter.

    Full Text Available The worldwide population increase and subsequent surge in energy demand leads electricity producers to increase supply in an attempt to generate larger profit margins. However, with Global Climate Change becoming a greater focus in engineering, it is critical for energy to be converted in as environmentally benign a way as possible. There are different sustainable methods to meet the energy demand. However, the focus of this research is in the area of Waste Heat Recovery. The waste heat stored in the exiting condenser cooling water is delivered to the air flow through a water-air cross flow heat exchanger. A converging thermal chimney structure is then applied to increase the velocity of the airflow. The accelerated air can be used to turn on the turbine-generator installed on the top the thermal chimney so that electricity can be generated. This system is effective in generating electricity from otherwise wasted heat.

  14. Recovery after abdominal wall reconstruction. (United States)

    Jensen, Kristian Kiim


    Incisional hernia is a common long-term complication to abdominal surgery, occurring in more than 20% of all patients. Some of these hernias become giant and affect patients in several ways. This patient group often experiences pain, decreased perceived body image, and loss of physical function, which results in a need for surgical repair of the giant hernia, known as abdominal wall reconstruction. In the current thesis, patients with a giant hernia were examined to achieve a better understanding of their physical and psychological function before and after abdominal wall reconstruction. Study I was a systematic review of the existing standardized methods for assessing quality of life after incisional hernia repair. After a systematic search in the electronic databases Embase and PubMed, a total of 26 studies using standardized measures for assessment of quality of life after incisional hernia repair were found. The most commonly used questionnaire was the generic Short-Form 36, which assesses overall health-related quality of life, addressing both physical and mental health. The second-most common questionnaire was the Carolinas Comfort Scale, which is a disease specific questionnaire addressing pain, movement limitation and mesh sensation in relation to a current or previous hernia. In total, eight different questionnaires were used at varying time points in the 26 studies. In conclusion, standardization of timing and method of quality of life assessment after incisional hernia repair was lacking. Study II was a case-control study of the effects of an enhanced recovery after surgery pathway for patients undergoing abdominal wall reconstruction for a giant hernia. Sixteen consecutive patients were included prospectively after the implementation of a new enhanced recovery after surgery pathway at the Digestive Disease Center, Bispebjerg Hospital, and compared to a control group of 16 patients included retrospectively in the period immediately prior to the

  15. Assessing the energy and environmental performance of algae-mediated tertiary treatment of estrogenic compounds. (United States)

    Colosi, Lisa M; Resurreccion, Eleazer P; Zhang, Yongli


    This study uses a systems-level modeling approach to illustrate a novel synergy between municipal wastewater treatment and large-scale algaculture for production of bio-energy, whereby algae-mediated tertiary treatment provides efficient removal of unregulated, strongly estrogenic steroid hormones from the secondary effluent. Laboratory results from previously published studies suggested that algae-mediated treatment could deliver roughly 75-85% removal of a model estrogen (17β-estradiol) within typical algae pond residence times. As such, experimental results are integrated into a comprehensive life cycle assessment (LCA) framework, to assess the environmental performance of an algae-based tertiary treatment system relative to three conventional tertiary treatments: ozonation, UV irradiation, and adsorption onto granular activated carbon. Results indicate that the algae-mediated tertiary treatment is superior to the selected benchmarks on the basis of raw energy return on investment (EROI) and normalized energy use per mass of estrogenic toxicity removed. It is the only tertiary treatment system that creates more energy than it consumes, and it delivers acceptable effluent quality for nutrient and coliform concentrations while rendering a significant reduction in estrogenic toxicity. These results highlight the dual water and energy sustainability benefits that accrue from the integration of municipal wastewater treatment and large-scale algae farming.

Braunschweig (Germany)


    Electricity consumption in the tertiary sector is still increasing - by 3 % per year between 1995 and 2005 in the EU-25 countries - and a further increase is expected of more than 2 % per year over the next 15 years. The tertiary sector includes companies and institutions of public and private services with very heterogeneous economic and energy-related characteristics. A study of the current state of data in the tertiary sector in European countries revealed that the availability of disaggregated data on electricity consumption and its use by purpose (lighting, office equipment, ventilation, air conditioning, etc.) is poor. Building managers and decision-makers are not well enough informed about the electricity consumption structure and electricity-saving potentials. EL-TERTIARY develops a harmonised methodology for monitoring electricity consumption and applies it in more than 100 cases in 12 EU countries. Implications for dissemination and energy efficiency policies will be derived. It is regarded as important to have an exchange of experiences on these issues within the scientific community and with actors and decision-makers in order to develop efficient instruments for practical use. EL-TERTIARY is an EU Intelligent Energy project under Key Action 4 'Energy efficient equipment and products'.

  17. Modification of the inlet to the tertiary air duct in the cement kiln installation

    Full Text Available Rotary kiln installation forms a very complex system, as it consists of various components which affect cement production. However, some problems with particle settling are encountered during operation of tertiary air installation. This paper reports on the results of a study into gas-particle flow in a tertiary air duct installation. This flow was calculated using Euler method for air motion and Lagrange method for particle motion. The results in this paper demonstrate that study focus on the tertiary air installation is a practical measure without the analysis of other processes in the rotary kiln. A solution to this problem offers several alternatives of modifying the inlet to the tertiary air duct. As a result of numerical calculations, we demonstrate the influence of geometry of a rotary kiln modification on the number of large particles transported in the tertiary air duct. The results indicate that in order to reduce large particles, rotary kiln head geometry needs to be modified, and a particle settler should be installed at its outlet.

  18. Comparison of biomechanical and anthropometrical data of Nigeria tertiary institution students with some selected countries

    Full Text Available The anthropometric data of student in selected tertiary institutions in Abeokuta, Ogun State, Nigeria was investigated and this was compared with some selected foreign countries. The study was to determine whether design improvement and further study is required in order to improve the conditions in Nigeria tertiary institutions. The anthropometrics measurements data were collected from 720 students of selected institutions. The data indicate a substantial degree of variability between the Nigerian tertiary students’ body and the foreign counterparts. Since most of the furniture in use in our tertiary institutions in Abeokuta, Nigeria were designed and constructed using the anthropometric data of students in foreign countries, there is need for anthropometric data of Nigerian students in the tertiary institution for the design and construction of furniture to suit them. The result is of great concern which could affect students in other institutions throughout Nigeria and could also pose a great risk of having back problem among students in Nigeria. Statement of Relevancy: The chair and table used in Nigeria were designed with reference to the measurement of other countries. The database of the Nigerian students will be very useful parameter in guiding principle for the designing of future equipment to be used in classrooms, laboratories and lecture theaters of the institutions.

The tensile tests investigate the free recovery (zero load) response as well as the constrained displacement recovery (stress recovery) response at extension values up to 25%, and two consecutive cycles are performed during each test. The material is observed to recover 100% of the applied deformati...

  20. Tertiary-amine-containing thermo- and pH-sensitive hydrophilic ABA triblock copolymers: effect of different tertiary amines on thermally induced sol-gel transitions. (United States)

    Henn, Daniel M; Wright, Roger A E; Woodcock, Jeremiah W; Hu, Bin; Zhao, Bin


    This Article reports on the synthesis of a series of well-defined, tertiary-amine-containing ABA triblock copolymers, composed of a poly(ethylene oxide) (PEO) central block and thermo- and pH-sensitive outer blocks, and the study of the effect of different tertiary amines on thermally induced sol-gel transition temperatures (T(sol-gel)) of their 10 wt % aqueous solutions. The doubly responsive ABA triblock copolymers were prepared from a difunctional PEO macroinitiator by atom transfer radical polymerization of methoxydi(ethylene glycol) methacrylate and ethoxydi(ethylene glycol) methacrylate at a feed molar ratio of 30:70 with ∼5 mol % of either N,N-diethylaminoethyl methacrylate (DEAEMA), N,N-diisopropylaminoethyl methacrylate, or N,N-di(n-butyl)aminoethyl methacrylate. The chain lengths of thermosensitive outer blocks and the molar contents of tertiary amines were very similar for all copolymers. Using rheological measurements, we determined the pH dependences of T(sol-gel) of 10 wt % aqueous solutions of these copolymers in a phosphate buffer. The T(sol-gel) versus pH curves of all polymers exhibited a sigmoidal shape. The T(sol-gel) increased with decreasing pH; the changes were small on both high and low pH sides. At a specific pH, the T(sol-gel) decreased with increasing the hydrophobicity of the tertiary amine, and upon decreasing pH the onset pH value for the T(sol-gel) to begin to increase noticeably was lower for the more hydrophobic tertiary amine-containing copolymer. In addition, we studied the effect of different tertiary amines on the release behavior of FITC-dextran from 10 wt % micellar gels in an acidic medium at 37 and 27 °C. The release profiles for three studied hydrogels at 37 °C were essentially the same, suggesting that the release was dominated by the diffusion of FITC-dextran. At 27 °C, the release was significantly faster for the DEAEMA-containing copolymer, indicating that both diffusion and gel dissolution contributed to the
