    Following rainfall, infiltrated water may be redistributed internally to larger depths or lost to the atmosphere by evaporation (and by plant uptake from depths at longer time scales). A large fraction of evaporative losses from terrestrial surfaces occurs during stage1 evaporation during which phase change occurs at the wet surface supplied by capillary flow from the soil. Recent studies have shown existence of a soil-dependent characteristic length below which capillary continuity is disrupted and a drastic shift to slower stage 2 evaporation ensues. Internal drainage hastens this transition and affect evaporative losses. To predict the transition to stage 2 and associated evaporative losses, we developed an analytical solution for evaporation dynamics with concurrent internal drainage. Expectedly, evaporative losses are suppressed when drainage is considered to different degrees depending on soil type and wetness. We observe that high initial water content supports rapid drainage and thus promotes the sheltering of soil water below the evaporation depth. The solution and laboratory experiments confirm nonlinear relationship between initial water content and total evaporative losses. The concept contributes to establishing bounds on regional surface evaporation considering rainfall characteristics and soil types.

    This article introduces a special collection of fourteen articles accepted from among the 140 technical presentations, posters, and meeting papers presented at the 10th International ASABE Drainage Symposium. The symposium continued in the tradition of previous symposia that began in 1965 as a forum for presenting and assessing the progress of drainage research and implementation throughout the world. The articles in this collection address a wide range of topics grouped into five broad categories: (1) crop response, (2) design and management, (3) hydrology and scale, (4) modeling, and (5) water quality. The collection provides valuable information for scientists, engineers, planners, and others working on crop production, water quality, and water quantity issues affected by agricultural drainage. The collection also provides perspectives on the challenges of increasing agricultural production in a changing climate, with ever-greater attention to water quality and quantity concerns that will require integrated technical, economic, and social solutions.

    Percutaneous biliary drainage is an important technique for palliative therapy of obstructive biliary disease and diagnostic information. The purpose of this study is to review and evaluate the experiences of ultrasound-guided percutaneous transhepatic biliary drainage. Ultrasound-guided percutaneous transhepatic biliary drainage was performed on 146 occasions in 134 patients. The causes of biliary obstruction were: benign diseases (19 cases, 14.2%) such as bile duct stones or stricture, cholangiocarcinoma (37 cases, 27.6%), pancreatic carcinoma (35 cases, 26.1%), metastasis (22 cases, 16.5%), gall bladder cancer (14 cases, 10.4%), ampulla of Vater cancer (4 cases, 3.0%), hepatocellular carcinoma (3 cases, 2.2%). Retrospectively reviewing medical records, we found out frequency of external or external/internal biliary drainages, puncture of left or right hepatic duct, and presence of bileinfection. Ultrasound-guided percutaneous transhepatic biliary drainage was compared with conventional biliary drainage of previous reports on the basis of frequency of complications. External (124 procedures, 84.9%) and external/internal biliary drainage (22 procedures, 15.1%) were carried out by puncture of dilated right (59.6%) or left (40.4%) intrahepatic duct. Sixty-nine complications occurred in 47 patients. Catheter related complications (33/69, 47.8%) were most common: catheter dislodgement (17/69, 24.6%), malfunction (9/69, 13.1%), leakage (7/69, 10.1%). Other minor complications such as simple fever (16/69, 23.2%), cholangitis (7/69, 10.1%), hemobilia (4/69, 5.8%), biloma (2/69, 2.9%) and wound infection (1/69, 1.5%) occurred. Major complications including sepsis (4/69, 5.8%) and bile peritonitis (2/69, 2.9%) were also noted. Puncture-related complications such as hemobilia, biloma and bile peritonitis occurred in 8 cases (5.5%). Comparing with conventional X-ray guided drainage, ultrasound-guided percutaneous transhepatic biliary drainage is a safe procedure for

    To evaluate the safety and efficacy of the M4 (porous polyethylene plate) Ahmed Glaucoma Valve (AGV) drainage implant in a multicenter retrospective study. A retrospective chart review of medical records of patients who had undergone the M4 Ahmed valve was performed from January 2013 to April 2015. The primary outcome measure was surgical failure defined as: Less than a 20% reduction in baseline intraocular pressure (IOP) to last follow-up visit, final IOP less than 5 mm Hg or greater than 18 mm Hg, reoperation for glaucoma, or loss of light perception vision. All eyes not meeting the above criteria were defined as success. A total of 291 eyes met all study inclusion criteria. The average follow-up in the study was 6 months (±7.6 months) with 112 patients achieving 12-month follow-up (38.5%). 208 eyes (71.5%) met the study success criteria at final follow-up. No statistically significant spikes in postoperative IOP at 1 and 4 months were detected. The average preoperative IOP was 26.0 on an average of 2.8 medications. At 6 months, the average IOP dropped to 16.7 on 0.9 medications and stayed relatively stable at 15.8 on 1.2 medications at 12-month follow-up. The M4 valve appears to have less of a hypertensive phase compared with the other Ahmed class valves with a similar safety profile. While 71.5% success rate was achieved at final follow-up, the failure rate steadily increased over time. While the M4 production has been discontinued, the porous design of the M4 may avoid a pressure spike in the Ahmed valve class and warrants future investigation for valve design.

    The so-called stent-related symptoms caused mainly by detrusor overactivity due to distal ("cystic") curl of the internal stent are common among patients with this type of drainage. The need for long-term stenting makes the quality of life of cancer patients one of the challenging problems of modern urology. The aim of this study was to optimize treatment of stent-related symptoms in cancer patients with internal long-term stents by complementing the treatment regimen with m-anticholinergic solifenacin. From November 2013 to November 2015 68 cancer patients (26 males, 42 females, age 36-79 years) underwent elective internal ureteral stenting for drainage of the upper urinary tract (UUT) with special long-term stents coated with the hydrogel. The urinary tract obstruction was caused by urological (24), gynecological (26) and colorectal (18) cancers. Before deciding on urinary tract drainage, all patients were treated with radiation or chemotherapy, 28 (41.2%) patients underwent surgery, but on admission all of them had contraindications to radical surgery for different reasons. In 52 (76.5%) patients UUT stenting was performed using transurethral access, in 12 (17.6%) by percutaneous access and in another 4 (5.9%) by the combined access with patients in the supine position. Percutaneous and combined access was used in cases of impracticability (failure) of transurethral stenting. Patients in group 1 (n=32) after stent placement received standard therapy co-administered with solifenacin 5 mg daily, group 2 (n=36) - only standard therapy. The data analyzed were the technical features of the internal drainage, optimal access and registered solifenacin-related adverse events. Control examinations were scheduled once in 3 months after stent placement according to the following algorithm: ultrasound scanning, laboratory test monitoring and, if indicated, plain urography. To objectify the severity of stent-related symptoms, a survey of patients using a special

    Full Text Available A 71-year-old man presented with a productive cough and fever, and he was diagnosed as having an esophageal perforation and a mediastinal abscess. He had a history of traumatic hemothorax and pleural drainage for empyema in the right chest and was considered unable to tolerate thoracic surgery because of sepsis and progressive aspiration pneumonia. In order to aggressively drain the mediastinal contamination, we performed internal drainage by placing a Levin tube into the mediastinum through the perforation site. This procedure, in conjunction with controlling sepsis and providing sufficient postpyloric nutrition, allowed the esophageal injury to completely heal.

    Percutaneous transhepatic biliary drainage (PTBD) is a form of palliative care for patients with malignant obstructive jaundice. We here compared the infection incidence between internal-external and external drainage for patients with malignant obstructive jaundice. Patients with malignant obstructive jaundice without infection before surgery receiving internal-external or external drainage from January 2008 to July 2014 were recruited. According to percutaneous transhepatic cholangiography (PTC), if the guide wire could pass through the occlusion and enter the duodenum, we recommended internal-external drainage, and external drainage biliary drainage was set up if the occlusion was not crossed. All patients with infection after procedure received a cultivation of blood and a bile bacteriological test. Among 110 patients with malignant obstructive jaundice, 22 (52.4%) were diagnosed with infection after the procedure in the internal-external drainage group, whereas 19 (27.9%) patients were so affected in the external drainage group, the difference being significant (pinternal-external group infection was controlled, as compared to 12 (63.1%) in the external group (pinternal-external group in one month was 42.8%, while this rate in external group was 28.6% (pExternal drainage is a good choice, which could significantly reduce the chance of biliary infection caused by bacteria, and decrease the mortality rate at one month and improve the long-term prognosis.

    The purpose of this study is to describe our experience with the role of CT-guided percutaneous drainage of loculated intra-abdominal collections consisting entirely of gas. An IRB-approved retrospective study analyzing patients with air-only intra-abdominal collections over an 8-year period was undertaken. Seven patients referred for percutaneous drainage were included. Size of collections, subsequent development of fluid, and microbiological yield were determined. Clinical outcome was also analyzed. Out of 2835 patients referred for percutaneous drainage between 2004 and 2012, seven patients (5M, 2F; average age 63, range 54-85) met criteria for inclusion with CT showing air-only collections. Percutaneous drain placement (five 8 Fr, one 10 Fr, and one 12 Fr) using Seldinger technique was performed. Four patients (57%) had recently undergone surgery (2 Whipple, 1 colectomy, 1 hepatic resection) while two (29%) had a remote surgery (1 abdominoperineal resection, 1 sigmoidectomy). Despite the lack of detectable fluid on the original CT, 6 patients (86%) had air and fluid aspirated at drainage, 5 (83%) of the aspirates developed positive microbacterial cultures. Four patients (57%) presented with fever at the time of the initial scan, all of whom had positive cultures from aspirated fluid. Four patients (57%) had leukocytosis, all of whom had positive cultures from aspirated fluid. Although relatively rare in occurrence, patients with air-only intra-abdominal collections with signs of infection should be considered for percutaneous management similar to that of conventional infected fluid collections. Although fluid is not visible on CT, these collections can produce fluid that contains organisms.

    Full Text Available Background and objective Mediastinal infection is a serious infection of mediastinal connective tissue, with more complications and higher mortality. Application of broad-spectrum antibiotics and nutritional support, early sufficient drainage is the key to successful treatment. In the mode of drainage, this paper discusses the application of continuous negative pressure drainage technique to treat acute anterior mediastinal infection of severe mouth pharynx source, and the good results are summarized and shared. Methods In January to December in 2017, a total of 17 cases treated acute mediastinal infection is derived from the throat, has formed a mediastinal abscess, surgery adopts retrosternal counterpart negative pressure drainage way, namely the sternum nest and free sternum xiphoid process under the incision on the first mediastinal clearance, make breakthrough and placed drainage device, suture closed wound, continuous negative pressure drainage, negative pressure using 3 cm-5 cm water column. Results Among the 17 patients, 14 patients were relieved by continuous negative pressure drainage, and then the drainage tube was removed. In 2 cases, the infection broke into the right thoracic cavity, and the closed drainage caused the negative pressure to disappear, and the negative pressure drainage was replaced by the conventional drainage, and the drainage tube was removed after the drainage tube was clear. One patient had formed a mediastinal abscess incision drainage time later, complicated with septic shock and sepsis, resulting in the death of multiple organ failure. Conclusion The traditional treatment of severe acute mediastinal infection is sternal incision and drainage. Continuous negative pressure drainage adequate drainage of mediastinal can relieve patients' pain, effusion, and avoid the dressing out repeatedly. It is an effective method. However, there are limitations in this method, which need to be further optimized.

  18. An improved analysis of gravity drainage experiments for estimating the unsaturated soil hydraulic functions

    Sisson, James B.; van Genuchten, Martinus Th.

    1991-04-01

    The unsaturated hydraulic properties are important parameters in any quantitative description of water and solute transport in partially saturated soils. Currently, most in situ methods for estimating the unsaturated hydraulic conductivity (K) are based on analyses that require estimates of the soil water flux and the pressure head gradient. These analyses typically involve differencing of field-measured pressure head (h) and volumetric water content (θ) data, a process that can significantly amplify instrumental and measurement errors. More reliable methods result when differencing of field data can be avoided. One such method is based on estimates of the gravity drainage curve K'(θ) = dK/dθ which may be computed from observations of θ and/or h during the drainage phase of infiltration drainage experiments assuming unit gradient hydraulic conditions. The purpose of this study was to compare estimates of the unsaturated soil hydraulic functions on the basis of different combinations of field data θ, h, K, and K'. Five different data sets were used for the analysis: (1) θ-h, (2) K-θ, (3) K'-θ (4) K-θ-h, and (5) K'-θ-h. The analysis was applied to previously published data for the Norfolk, Troup, and Bethany soils. The K-θ-h and K'-θ-h data sets consistently produced nearly identical estimates of the hydraulic functions. The K-θ and K'-θ data also resulted in similar curves, although results in this case were less consistent than those produced by the K-θ-h and K'-θ-h data sets. We conclude from this study that differencing of field data can be avoided and hence that there is no need to calculate soil water fluxes and pressure head gradients from inherently noisy field-measured θ and h data. The gravity drainage analysis also provides results over a much broader range of hydraulic conductivity values than is possible with the more standard instantaneous profile analysis, especially when augmented with independently measured soil water retention data.

    Stormwater management (SWM) includes a wide range of services aimed at environmental protection, enhancement of water resources and flood control. Local governments are responsible for managing all these aspects within their jurisdiction, but they often present limitations in generating revenues. Thus, many municipalities have been seeking a dedicated funding source for these programs and practices. This publication provides a brief overview of current legal issues associated with stormwater funding focusing on the most used method: fees. It is a successful mechanism to fund legal obligations of municipalities; however, it must have a significant value to motivate the reduction of runoff. Through literature, we found stormwater fees in Australia, Brazil, Canada, Ecuador, France, Germany, Poland, South Africa and the United States (USA). France had the highest average monthly fee, but this financing experience was suspended in 2014. Brazil has the lowest fee by m², comparable to the US fee. While in Brazil overall SWM represents low priority investments, the USA represents one of the most evolved countries in stormwater funding practices. It was noticed by reviewing the international experience that charging stormwater fees is a successful mechanism to fund the legal obligations and environmental protection.

    Nanofiltration of real uranium-contaminated mine drainage was successfully discussed in experiments and modeling. For the simulation a renowned model was adapted that is capable of describing multi-component solutions. Although the description of synthetic multi-component solutions with a limited number of components was performed before ([Garcia-Aleman2004], [Geraldes2006], [Bandini2003]) the results of this work show that the adapted model is capable of describing the very complex solution. The model developed here is based on: The Donnan-Steric Partitioning Pore Model incorporating Dielectric Exclusion - DSPM and DE ref. [Bowen1997], [Bandini2003], [Bowen2002], [Vezzani2002]. The steric, electric, and dielectric exclusion model - SEDE ref. [Szymczyk2005]. The developed modeling approach is capable of describing multi-component transport, and is based on the pore radius, membrane thickness, and volumetric membrane charge density as physically relevant membrane parameters instead of mere fitting parameters which allows conclusions concerning membrane modification or process design. The experiments involve typical commercially available membranes in combination with a water sample of industrial relevance in the mining sector. Furthermore, it has been shown experimentally that uranium speciation influences its retention. Hence, all experiments consider the speciation of uranium when assessing its charge and size. In the simulation 10 different ionic components have been taken into account. By freely fitting 4 parameters in parallel (pore radius, membrane thickness, membrane charge, relative permittivity of the oriented water layer at the pore wall) an excellent agreement between experiment and simulation was obtained. Moreover, the determined membrane thickness and pore radius is in close agreement with the values obtained by independent membrane characterization using pure water permeability and glucose retention. On the other hand, the fitted and the literature

    Full Text Available Experimentally determined values of unsaturated soil hydraulic conductivity are presented for an Alfisol of the county of Piracicaba, S.P., Brazil. Simultaneous measurements of soil water content and pressure head are made along a 125 m transect within an irrigated field during the internal drainage process. Calculations of the soil hydraulic conductivity were made using the instantaneous profile method (Watson, 1966 and the unit gradient method (LIBARDI et al., 1980. The spatial variability of the soil hydraulic conductivity manifested along the transect indicates the need to develop a field method to measure K(theta within prescribed fiducial limits, taking into account quantitative evaluation of spatial and temporal variances associated with the mathematical model, instrument calibration and soil properties.São apresentados dados experimentais de condutividade hidráulica do solo, para uní Alfisol (terra roxa estruturada do Município de Piracicaba,SP - Brasil.

    A pumping test was carried out to explore the transfer rules of pressure drop in coal reservoir during the drainage. The experiment was divided into three stages. In the first stage, the pump displacement of 3m3/h was used to reduce the bottom hole flowing pressure and stopped until the continuous gas phase was produced; Undertaking the first stage, in the second stage, when the gas phase was continuously produced, the pump was stopped immediately. As the bottom hole flowing pressure going up without gas phase, pumping started again for a week. In the third stage ,the well pumping was carried out at the bottom hole pressure drop rate of 30Kpa/d after two months' recovery. Combined with the data of regional geology and fractured well, taking the characteristics of macroscopic coal rocks, development of pore and fracture in coal and isothermal adsorption test as the background, the features of reservoir output in each stage of the experiment were analyzed and compared, and then the transfer rules of pressure drop contained in the differences of the output was studied further. In the first and third stage of the experiment, the output of liquid phase was much larger than the space volume of coal reservoir pore and fracture in the range of 100m2. In the second stage, the output of the continuous gas phase appeared around 0.7Mpa when the continuous gas phase appears below the critical desorption pressure of 0.25Mpa during the whole experiment. The results indicate that, the transfer of pressure drop in the coal reservoir of this well is mainly horizontal, and the liquid phase produced in the reservoir mainly comes from the recharge of the reservoir at the far end of the relative high pressure area; the adsorption space of coalbed methane in the coal matrix as well as the main migration channel of fluid in the reservoir doesn't belong to the same pressure system and there exists the communication barrier between them. In addition, the increasing of the effective stress

One key issue is management of risk and uncertainties and therefore a framework for design......Climate change will influence the water cycle substantially, and extreme precipitation will become more frequent in many regions in the years to come. How should this fact be incorporated into design of urban drainage systems, if at all? And how important is climate change compared to other changes...... and analysis of urban structures in light of present and future uncertainties is presented....

    Highlights: > Organic carbon amendments can support passive treatment of mine drainage. > Decreased transport of sulfide-oxidation products under sulfate-reducing conditions. > Treatment effectiveness dependent on organic carbon source and amendment rate. - Abstract: A field-scale experiment was conducted to evaluate various organic C sources as amendments for passive treatment of tailings pore water. Varied mixtures of peat, spent-brewing grain (SBG) and municipal biosolids (MB) were assessed for the potential to promote dissimilatory sulfate reduction (DSR) and metal-sulfide precipitation. Five amended cells and one control were constructed in the vadose zone of a sulfide- and carbonate-rich tailings deposit, and the geochemistry, microbiology and mineralogy were monitored for 4 a. Increases in pore-water concentrations of dissolved organic C (DOC) and decreases in aqueous SO{sub 4} concentrations of >2500 mg L{sup -1} were observed in cells amended with peat + SBG and peat + SBG + MB. Removal of SO{sub 4} was accompanied by shifts in {delta}{sup 34}S-SO{sub 4} values of >+30 per mille, undersaturation of pore water with respect to gypsum [CaSO{sub 4}.2H{sub 2}O], and increased populations of SO{sub 4}-reducing bacteria (SRB). Decreases in aqueous concentrations of Zn, Mn, Ni, Sb and Tl were observed for these cells relative to the control. Organic C introduction also supported growth of Fe-reducing bacteria (IRB) and increases in Fe and As concentrations. Enhanced Fe and As mobility occurred in all cells; however, maximum concentrations were observed in cells amended with MB. Subsequent decreases in Fe and As concentrations were attributed to DSR and metal-sulfide precipitation. The common presence of secondary Zn-S and Fe-S phases was observed by field emission-scanning electron microscopy (FE-SEM) and energy dispersive X-ray (EDS) spectroscopy. Selective extractions indicated that large decreases in water-soluble SO{sub 4} occurred in cells that supported DSR

    1985-06-01

    Thirty patients with obstructive jaundice with plasma bilirubin values greater than 200 mumol/L were randomized at the time of percutaneous transhepatic Cholangiography to undergo immediate or delayed surgery. The patients who had preoperative percutaneous transhepatic biliary drainage (PTBD) for 13.8 +/- 5.8 days had fewer surgical complications than did patients who underwent immediate surgery (p less than 0.02), although when the complications of PTBD were included this advantage was diminished. Immediate surgery caused greater deterioration of renal function as measured by plasma urea, plasma B 2-microglobulin, phosphate clearance, uric acid clearance, and maximal concentrating ability than occurred after PTBD or delayed surgery. The improvement in phosphate clearance that followed PTBD was sustained through delayed surgical treatment, indicating better tubular function in these patients. This article supports the concept that preoperative PTBD will reduce surgical morbidity and will result in less renal impairment than will immediate surgery. However, the morbidity rates of the PTBD procedure will preclude its wide use.

    In 69 patients with extrahepatic biliary obstruction a specially designed teflon tube, the endoprosthesis, was inserted across the ductal stenosis either by percutaneous or by endoscopic route to reduce jaundice. After gaining experience our success rate of stent placement was more than 90%. Compared with catheter drainage the endoprosthesis worked faster and more efficiently, while in palliative treatment the quality of life of the patient improved and secondary cholangitis was prevented. The rate of significant long-term stent obstruction can be tolerated in view of the expected life span of four months as an average in our material.

    To identify reasons for inclusion of international practice experiences in pharmacy curricula and to understand the related structure, benefits, and challenges related to the programs. A convenience sample of 20 colleges and schools of pharmacy in the United States with international pharmacy education programs was used. Telephone interviews were conducted by 2 study investigators. University values and strategic planning were among key driving forces in the development of programs. Global awareness and cultural competency requirements added impetus to program development. Participants' advice for creating an international practice experience program included an emphasis on the value of working with university health professions programs and established travel programs. Despite challenges, colleges and schools of pharmacy value the importance of international pharmacy education for pharmacy students as it increases global awareness of health needs and cultural competencies.

  14. Polarized internal targets for electronuclear experiments

    1993-01-01

    Polarized internal gas targets represent a unique opportunity for the measurement of spin observables in electro-nuclear physics. Two measurements will be discussed. First, spin observables have been measured in elastic and quasi-free scattering of 45, 200, 300, and 415 MeV polarized protons from a polarized 3 He internal gas target at the Indiana University Cyclotron Facility Cooler Ring. The data obtained constitute the first measurement of spin correlation parameters using a storage ring with polarized beam and polarized internal gas target. Second, a quasi-free (e,e'p) experiment using tensor polarized deuterium will be discussed. Here, the goal is the measurement of the S- and D-state parts of the proton spectral function by scattering 700 MeV electrons from an atomic beam source. Large acceptance detectors have been used in both experiments. The internal-target technique has broad applicability in nuclear and particle physics

    Full Text Available Abstract Background Despite breast abscess becoming less common in developed countries, it has remained one of the leading causes of morbidity in women in developing countries. A randomized controlled trial was conducted at Mulago hospital complex in Kampala Uganda to establish whether ultrasound guided needle aspiration is a feasible alternative treatment option for breast abscesses. Results A total of 65 females with breast abscess were analyzed, of these 33 patients were randomized into the ultrasound guided needle aspiration and 32 patients in the Incision and drainage arm. The mean age was 23.12, most of them were lactating (66.2%, primipararous (44.6% with peripheral abscesses (73.8% located in the upper lateral quadrant (56%.The mean breast size was 3.49 cm. The two groups were comparably in demographic characteristic and breast abscess size. Survival analysis showed no difference in breast abscess healing rate between the two groups (Log rank 0.24 df 1 and P = 0.63. Incision and drainage was found to be more costly than ultrasound guided aspiration (cost effective ratio of 2.85. Conclusion Ultrasound guided needle aspiration is therefore a feasible and cost effective treatment option for both lactating and non lactating breast abscesses with a diameter up to 5 cm by ultrasound in an immune competent patient

    Malignant pleural effusions are common and can be difficult to manage. We have reviewed our use of ambulatory drains (Pleurex drains) in this regard with particular reference to hospital stay, duration of drainage, and incidence of complications. Of 125 patients with malignant pleural effusion with trapped lung or failed previous pleurodesis who underwent insertion of ambulatory pleural drain, 41 patients were under local anesthesia and 84 patients were under general anesthesia. Mean age was 66.5 years with male:female = 80:45. Data were collected retrospectively from the clinical notes, and the family doctors' clinics were contacted to enquire about the patients' survival. When data collection concluded, 48 patients (38.4%) had died, giving mean survival following drain insertion of 84.1 days. There were no in-hospital deaths related to the procedure. One procedure was converted to a mini-thoracotomy to control bleeding from a lung tear. Mean duration of catheter placement was 87.01 days (5-434). Video-assisted thoracoscopic surgery was used in 77 patients (61.6%), and Seldinger's technique was used in 48 patients (38.4%). Mesothelioma was the most common malignant cause. Minor complications were encountered in 15 patients (12%), and they were managed as outpatients. The use of ambulatory pleural catheters for managing malignant pleural effusion is a safe and effective strategy. It has only minor complications that are related to prolonged drainage. We feel that this strategy should be considered the first choice option for these patients.

  18. Experience with mechanical segmentation of reactor internals

    International Nuclear Information System (INIS)

    Carlson, R.; Hedin, G.

    2003-01-01

    Operating experience from BWE:s world-wide has shown that many plants experience initial cracking of the reactor internals after approximately 20 to 25 years of service life. This ''mid-life crisis'', considering a plant design life of 40 years, is now being addressed by many utilities. Successful resolution of these issues should give many more years of trouble-free operation. Replacement of reactor internals could be, in many cases, the most favourable option to achieve this. The proactive strategy of many utilities to replace internals in a planned way is a market-driven effort to minimize the overall costs for power generation, including time spent for handling contingencies and unplanned outages. Based on technical analyses, knowledge about component market prices and in-house costs, a cost-effective, optimized strategy for inspection, mitigation and replacements can be implemented. Also decommissioning of nuclear plants has become a reality for many utilities as numerous plants worldwide are closed due to age and/or other reasons. These facts address a need for safe, fast and cost-effective methods for segmentation of internals. Westinghouse has over the last years developed methods for segmentation of internals and has also carried out successful segmentation projects. Our experience from the segmentation business for Nordic BWR:s is that the most important parameters to consider when choosing a method and equipment for a segmentation project are: - Safety, - Cost-effectiveness, - Cleanliness, - Reliability.

    Aim: To evaluate the efficacy of ultrasound-guided percutaneous drainage of symptomatic meniscal cysts. Materials and methods: Patients with lateral knee joint tenderness and swelling and confirmed meniscal cyst on magnetic resonance imaging (MRI) were consecutively enrolled for ultrasound-guided percutaneous cyst aspiration. Cysts were injected with local anaesthetic and steroid before completion of procedure. All 18 patients (all male, average age 33 years) were subsequently followed up (average time 10 months) and meniscal cyst symptoms assessed by questionnaire. Fischer's exact test used to analyse the data. Results: In every case the procedure was well tolerated, and each patient indicated that they would be willing to have a repeat procedure in the future. Ten patients reported complete resolution of symptoms secondary to therapeutic cyst aspiration and had resumed participation in high-performance sport. Two patients reported a satisfactory sustained response, reporting only occasional 'twinges of pain'. In the remaining six patients, symptoms returned after an initial pain-free period. The pain-free period ranged from 1-8 weeks. In this study, patient outcome did not significantly correlate with any meniscal cyst characteristic. Conclusion: Ultrasound-guided percutaneous aspiration of meniscal cysts is a well-tolerated, simple, and safe procedure. In this small patient series, it was associated with positive early results with favourable outcomes in the mid to long-term. It should be considered in patients unsuitable for surgical debridement or as an interim therapy if surgery is delayed or postponed

    Westinghouse capitalizes more than 30 years of experience in the cutting of internal components of reactor and their packaging in view of their storage. Westinghouse has developed and validated different methods for cutting: plasma torch cutting, high pressure abrasive water jet cutting, electric discharge cutting and mechanical cutting. A long feedback experience has enabled Westinghouse to list the pros and cons of each cutting technology. The plasma torch cutting is fast but rises dosimetry concerns linked to the control of the cuttings and the clarity of water. Abrasive water jet cutting requires the installation of costly safety devices and of an equipment for filtering water but this technology allows accurate cuttings in hard-to-reach zones. Mechanical cutting is the most favourable technology in terms of wastes generation and of the clarity of water but the cutting speed is low. (A.C.)

    Full Text Available The experience of organizing school nutrition in Europe and usais analyzed. It is noted that long term programs aimed at optimizing schoolchildren nutrition have a beneficial effect on the children's health, culture of their nutrition and quality of life. The importance of carrying out similar programs in Russia is beyond any doubt: according to population research, the basic principles of good nutrition are often not observed, and school breakfasts and lunches do not correspond to the age physiological needs of children and teenagers for nutrient materials and energy. In this situation, the available experience of using vitaminbenriched products as well as vitamin and mineral complexes in children will permit to quickly resolve the existing problems of the improper, and sometimes, insufficient, nutrition.Key words: school nutrition, organization, international experience.

    1991-04-01

    The purpose of this report is to compile and present in a clear form international experience (USA, Canada, Sweden, FRG, UK, Japan, Switzerland) gained to date in conditioning spent fuel elements. The term conditioning is here taken to mean the handling and packaging of spent fuel elements for short- or long-term storage or final disposal. Plants of a varying nature fall within this scope, both in terms of the type of fuel element treated and the plant purpose eg. experimental or production plant. Emphasis is given to plants which bear some similarity to the concept developed in Germany for direct disposal of spent fuel elements. Worldwide, however, relatively few conditioning plants are in existence or have been conceived. Hence additional plants have been included where aspects of the experience gained are also of relevance eg. plants developed for the consolidation of spent fuel elements. (orig./HP) [de

    This paper reports the results of an artificial channel experiment in which water containing arsenic was purified by using Eleocharis acicularis. The experiment was conducted to investigate the feasibility of phytoremediation by Eleocharis acicularis in civil engineering projects. In the experiment, 15 m2 of Eleocharis acicularis mats were laid in an artificial channel. Three sessions of artificial flow were implemented by leading 100.0 L of river water containing 0.234 mg/L of arsenic into the channel each time. The arsenic concentration of the leachate from the channel was analyzed. As the results of experiment, the arsenic concentrations of the leachate for the three sessions were 0.045 mg/L, 0.133 mg/L, and 0.249 mg/L. This shows that the arsenic concentration decreased during the first two sessions, whose flow totaled 200 L. The arsenic concentrations in the Eleocharis acicularis were 0.87 mg/kg, 1.01 mg/kg, and 4.16 mg/kg, which show that the plant absorbs arsenic. Moreover, it was found that the amount of sample water was reduced through evapotranspiration from the plant and the artificial channel.

    1979-08-01

    Endoscopically placed inlying ureteral stents have proved useful in the conservative management of patients with ureteral obstruction, urinary fistula, and malignancy and have obviated the need for operative intervention. In high-risk symptomatic patients with widespread malignancy, internal urinary diversion offers the opportunity for an improved quality of life without the surgical risk or potential morbidity of supravesical diversion. Potential candidates for this simple, safe, and effective technique include: those with postsurgical obstruction and/or fistula, retroperitoneal fibrosis, metastatic carcinoma, congenital ureteropelvic junction obstruction, as well as those with reversible obstruction from lymphoma and carcinoma of the prostate who are undergoing radiotherapy and/or chemotherapy. The focus of this report is on the technique we have found successful in providing us with stents that fit our individual patients. Readily available fabricated graduated ureteral catheter can be cut and shaped to particular measurements unlike prefabricated catheters. Minimal preparation time is demanded, and there is no need for extensive stocking of various catheter sizes.

    2017-11-01

    Full Text Available The article is aimed at generalizing the foreign experience of implementing public procurement, analyzing peculiarities of organizational, normative and procedural provision of public procurement in the Member States of the European Union. The relevance of the research topic is due to the need to harmonize the procurement policy of the Government of Ukraine with the international legal framework and with broad political objectives within the European integration strategy. The organizational framework and principles of implementing public procurement in the EU Member States were analyzed. Special attention was paid to normative provision of public procurement by the EU Member States; peculiarities of the use of national or harmonized rules of public procurement in accordance with the amount of the procurement contract; restrictions and conditions for public authorities in the selection of applicants for bidding. Five types of public procurement procedures used in the EU have been characterized, namely: open procedure, limited procedure, negotiation procedure, competitive dialog, electronic auctions. The need to address the social and legal aspects of public procurement in international practice has been substantiated and the possibilities for resolving these problems have been presented.

    This study was designed to evaluate the efficacy and safety of computed tomography (CT)-guided drainage in treating infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity. From January 2007 to June 2009, 21 patients (9 men and 12 women; mean age, 39.2 (range, 26–52) years) with infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity underwent image-guided percutaneous drainage. All procedures were performed using CT guidance and 8- to 12-Fr pigtail drainage catheters. Immediate technical success was achieved in all 21 infected collections. In 18 of 21 collections, we obtained progressive shrinkage of the collection with consequent clinical success (success rate 86%). In three cases, the abdominal fluid collection was not resolved, and the patients were reoperated. Among the 18 patients who avoided surgery, 2 needed replacement of the catheter due to obstruction. No major complications occurred during the procedure. The results of our study support that CT-guided percutaneous drainage is an effective and safe method to treat infected abdominal fluid collections due to gastric leak in patients who had previously underwent laparoscopic sleeve gastrectomy for morbid obesity. It may be considered both as a preparatory step for surgery and a valuable alternative to open surgery. Failure of the procedure does not, however, preclude a subsequent surgical operation.

    The determination of the hydraulic properties of an alluvial soil in Cajueiro reservoir has been carried out in two experimental plots of 3.5 m x 3.5 m, installed in the opposite banks of the brook in which is located the dam, (Tuparetama Country, Pernambuco). For the determination of the hydraulic conductivity as a function of the soil water volumetric content K(θ), the internal driainage method proposed by Hillel et al. (1972) has been applied. The soil-water retention curves h (θ) have been determined through the experimental data of volumetric water content and pressure obtained in field experiments. The h (θ) and K (θ) curves have been fitted to van Genuchten's closed - form equations (1980), using the Burdine's model, and Brooks and Corey's model, respectively. The volumetric water content, matric potential, and total water content estimates have been fitted to two analytical functions: one being composed by the addition of three exponentials terms the other composed and by representation the reverse of the power functions. The latter has been preferred due to its smoother representation between the fast and the slow its drainage phases. Considering the hydraulic behavior, three different layers have been identified in the soil profiles of the two experimental parcels A2 and B4 in the alluvial soil Cajueiro reservoir. The second layer of the soil profile in parcel A2 turned out the more pemeable than the other two layers. As to the soil profile in parcel B4, the first layer turned out more conductive than the other layers. However, the biggest volumetric water content variations were due to the differences found in the texture and structure of the soil profiles under study. The hydrodynamic characterization of the two soil profiles, A2 and B4, brings significant elements for the simulation of scenarios related to the soil of water transport processes. It is of particular importance the study of scenarios related to the shallow soil layers, which are

    2002-01-01

    'Full text:' Agricultural drainage systems have been identified as potential contributors of non-point source pollution. Two of the major concerns have been with nitrate-nitrogen (NO3 - -N) concentrations and bacteria levels exceeding the Maximum Acceptable Concentration in drainage water. Heightened public awareness of environmental issues has led to greater pressure to maintain the environmental quality of water systems. In an ongoing field study, three experiment sites, each with own soil properties and characteristics, are divided into drainage plots and being monitored for NO3 - -N and fecal coliforms contamination. The first site is being used to determine the impact of the rate of manure application on subsurface drainage water quality. The second site is being used to determine the difference between hog manure and inorganic fertilizer in relation to fecal coliforms and NO3-N leaching losses under a carrot rotation system. The third site examines the effect of timing of manure application on water quality, and is the only site equipped with a surface drainage system, as well as a subsurface drainage system. Each of the drains from these fields lead to heated outflow buildings to allow for year-round measurements of flow rates and water samples. Tipping buckets wired to data-loggers record the outflow from each outlet pipe on an hourly basis. Water samples, collected from the flowing drains, are analyzed for NO3 - -N concentrations using the colorimetric method, and fecal coliforms using the Most Probable Number (MPN) method. Based on this information, we will be able better positioned to assess agricultural impacts on water resources which will help towards the development on industry accepted farming practices.

  20. International boundary experiences by the United Nations

    Science.gov (United States)

    Kagawa, A.

    2013-12-01

    Over the last few decades, the United Nations (UN) has been approached by Security Council and Member States on international boundary issues. The United Nations regards the adequate delimitation and demarcation of international boundaries as a very important element for the maintenance of peace and security in fragile post-conflict situations, establishment of friendly relationships and cross-border cooperation between States. This paper will present the main principles and framework the United Nations applies to support the process of international boundary delimitation and demarcation activities. The United Nations is involved in international boundary issues following the principle of impartiality and neutrality and its role as mediator. Since international boundary issues are multi-faceted, a range of expertise is required and the United Nations Secretariat is in a good position to provide diverse expertise within the multiple departments. Expertise in different departments ranging from legal, political, technical, administrative and logistical are mobilised in different ways to provide support to Member States depending on their specific needs. This presentation aims to highlight some of the international boundary projects that the United Nations Cartographic Section has been involved in order to provide the technical support to different boundary requirements as each international boundary issue requires specific focus and attention whether it be in preparation, delimitation, demarcation or management. Increasingly, the United Nations is leveraging geospatial technology to facilitate boundary delimitation and demarcation process between Member States. Through the presentation of the various case studies ranging from Iraq - Kuwait, Israel - Lebanon (Blue Line), Eritrea - Ethiopia, Cyprus (Green Line), Cameroon - Nigeria, Sudan - South Sudan, it will illustrate how geospatial technology is increasingly used to carry out the support.

    A key aspect of electricity industry reorganization is transmission pricing because it heavily influences the degree of effective competition in 'liberalized' electricity markets. this paper presents an overview transmission pricing models, of issues related to an effective design of a transmission pricing approach, and presents approaches implemented internationally. A conclusion is that, due to the great number of institutional designs of electricity market organizations, particularly in Europe, it will be difficult to design/implement a model of cross-border transmission pricing that is capable of inducing a high degree of non-discriminatory international competition in electricity markets.

    To cope with the recent challenges within the health care industry, health care managers need to engage in the internal marketing of their various services. Internal marketing has been used as an effective management tool to increase employees' motivation, satisfaction, and productivity (J Mark Commun. 2010;16(5):325-344). Health care managers should understand that an intense focus on internal marketing factors will lead to a quality experience for employees that will ultimately have a positive effect on the patient experiences.

    With the success of percutaneous abdominal abscess drainage, attention is now being focused on the use of similar techniques in the thorax. We studied to evaluate the effect of percutaneous drainage in parenchymal fluid collections in the lungs. We performed percutaneous drainage of abscesses and other parenchymal fluid collections of the lungs in 15 patients. All of the procedures were performed under the fluoroscopic guidance with an 18-gauge Seldinger needle and coaxial technique with a 8-10F drainage catheter. Among 10 patients with lung abscess, 8 patients improved by percutaneous catheter drainage. In one patient, drainage was failed by the accidental withdrawal of the catheter before complete drainage. One patient died of sepsis 5 hours after the procedure. Among three patients with complicated bulla, successful drainage was done in two patients, but in the remaining patient, the procedure was failed. In one patient with intrapulmonary bronchogenic cyst, the drainage was not successful due to the thick internal contents. In one patient with traumatic hematoma, after the drainage of old blood clots, the signs of infection disappeared. Overally, of 14 patients excluding one who died, 11 patients improved with percutaneous catheter drainage and three patients did not. There were no major complications during and after the procedure. We conclude that percutaneous catheter drainage is effective and safe procedure for the treatment of parenchymal fluid collections of the lung in patients unresponsive to the medical treatment

    A large variety of JET discharges with internal transport barriers (ITBs) has been analysed in order to determine the main features which characterize turbulence stabilization at the barrier. It is found that the location of barriers is well correlated with regions where the ExB flow shearing rate exceeds the linear growth rate of the ion temperature gradient mode instability ({gamma}{sub {eta}{sub i}}). A key point is the dependence of {gamma}{sub {eta}{sub i}} on the magnetic shear: in the discharges of this database the reduction of {gamma}{sub {eta}{sub i}} associated to very low or null magnetic shear favours the formation of an ITB. After the ITB formation a positive feedback occurs in which the ExB flow shear mechanism has the leading role and the position of the barrier may be no longer linked to the low shear region.

    33 abdominal abscesses associated with fistulae in 31 patients were treated by percutaneous drainage. 19 of these patients had had surgery immediately preceding the drainage. In 64% the percutaneous drainage led to a diagnosis of an internal fistula. Additional therapeutic measures, because of the fistula, were necessary in 45% (operation, biliary drainage, repositioning of catheter). The average duration of drainage was 29 days. 77% of those abscesses which could be drained were treated successfully. Mortality in the entire series was 19%. (orig.) [de

  11. Determinants of International Migration: The Nigerian Experience

    2014-01-01

    Full Text Available This paper examines some determinants of international migration in Nigeria using annual time series data spanning the period 1991–2011. Using ordinary least square regression method, the results indicate that the level of unemployment, migrants’ remittances and population growth are the key determinants of emigration from Nigeria to other countries, statistically significant at 0.01 level.In a country where unemployment rate is very high, this movement is likely to help in reducing pressures on the labour market. Migrants’ remittances might also help in alleviating poverty within households. Migrants’ remittance to Nigeria has surpassed both Foreign Direct Investment and Net Official Development Assistance inflows, making it one amongst the major sources of foreign earnings to Nigeria. Nigerians will continue to migrate to other parts of the world so long as the reasons or causes for their movement are not fully addressed i.e. if political and socioeconomic issues in the country do not improve. The Nigerian government should as a matter of urgency, create better jobs and conducive environment in order to stop people from migrating while at the same time encouraging its skilled labour abroad to return home to help in national development.

    The role of preoperative biliary drainage (PBD) for periampullary and hilar malignancy is still controversial. We retrospectively studied consecutive 144 patients (92 periampullary and 52 hilar malignancy) undergoing surgical resection to evaluate the effects of PBD on surgical outcomes. The rate of PBD was 59% and 56%, and postoperative complications developed in 27% and 19% in periampullary and hilar malignancy, respectively. Risk factors for postoperative complications were overweight [odds ratio (OR), 7.6] and depression (OR, 8.5) in distal malignancy and American society of anesthesiologists score of 3 (OR, 6.6), depression (OR, 13.8), and portal vein embolization (OR, 6.1) in hilar malignancy. PBD was not associated with postoperative complications but reinterventions for PBD were necessary in 43% and 27% in distal and hilar biliary obstruction. In conclusion, PBD in pancreatobiliary surgery was not associated with postoperative complications, but the improvement of PBD is necessary given the high rate of reinterventions.

    2014-01-01

    The systematic analysis of safety-relevant events in nuclear power plants and their causes is a key driver for the further development of nuclear safety. The findings obtained from the evaluation of operating experience in this respect form the basis for both technical and organisational improvements in the plants as well as for adaptations of technical rules and standards. In its role as Technical Safety Organisation advising the German federal government, Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) has been concerned with the detection and analysis of failure mechanisms that underlie events in nuclear power plants at home and abroad since its foundation in 1977. This article provides an overview of the different objectives which are pursued in this context by order of or funded by the Federal Environment Ministry. Here, the focus is on the evaluation of reportable events for the preparation of so-called Information Notices and generic reports as well as for the acquisition of data that can be used for in-depth probabilistic analyses.

    Ali, H. N.; Atekwana, E. A.

    2007-05-01

    Water from an acid mine drainage spring, ground water from a mine tailings pile, stream water and tap water were acidified to simulate acid mine drainage (AMD) contamination. The objective was to determine how acidification of stream water by AMD affected DIC loss and carbon isotope fraction. Two 20 L HDP containers (reactors) containing samples from each source were left un-acidified and allowed to evolve under ambient conditions for several weeks in the laboratory and two others were acidified. Acidification was carried out progressively with sulfuric acid to pH <3. For acidified samples, one reactor was acidified open to the atmosphere and the other closed from contact with atmosphere and CO2(g) was collected under vacuum. The un-acidified samples did not show significant alkalinity and DIC loss, and the 13C of DIC was enriched with time. The acidified samples showed decrease in alkalinity and DIC and increase in the 13C of DIC and CO2(g) with progressive acidification. The enrichment of 13C of DIC for un-acidified samples was due to exchange with atmospheric CO2. On the other hand, the 13C enrichment in the acidified samples was due to fractionation during dehydration of HCO3- and diffusive loss of CO2(g) from the aqueous phase. The actual values measured depended on the amount of CO2 lost from the aqueous phase during acidification. Samples with greater CO2 loss (closed acidification) had greater 13C enrichment. Beyond the HCO3- titration end point, the δ13C of DIC and CO2(g) was similar and nearly constant. The result of this study suggests that AMD effects on DIC can be modeled as a first order kinetic reaction and the isotope enrichment modeled using Rayleigh distillation.

  5. International experiences with power supply crises

    International Nuclear Information System (INIS)

    2002-01-01

    Many so-called deregulated power markets experience a hardened energy and power balance and some have had supply crises. This report discusses the crises, their impacts and their causes as well as the measures taken by the authorities to solve the crises. It also considers the similarities or dissimilarities with respect to the situation in Norway the winter 2002/2003. Like Norway, many of the countries have a considerable share of hydroelectric power. It is found, however, that the dependence on water of its own is not the reason for the crises, but that the inflow conditions give the market greater challenges. Furthermore, the Norwegian market has greater flexibility in the consumption, greater import capacity, better price security possibilities and less problems with market power than most of the countries here considered. Various factors influence a country's power consumption and production capacity. Economic growth and the availability of inexpensive power contribute to accelerate the consumption, while predictable external conditions and sufficient expected investment earnings are necessary to achieve an increase of the capacity - both through new investments and attendance to existing capacity. In a smooth power market there must be a certain correspondence between consumption and installed capacity, and the capacity must be such that it can cover the continuous demand for power and at the same time be flexible enough to deliver power at peak loads. This is also true of the transmission capacity. In addition, some extra capacity must be available for unexpected events. The basic problem is, in any power market, that the consumption may rise fast, while the investments in new capacity typically occurs in leaps, with long and costly construction phases. Many countries have lately experienced a hardening of the balance between consumption and capacity and so have been vulnerable to unexpected increases in consumption or resource failure. This was also the

    While open drainage has been the standard treatment for pancreatic pseudocysts, less invasive technique which pay little attention to cyst wall biopsy are becoming popular. The aim of this study is to report on our experience in draining pancreatic pseudocysts and probe the necessity or otherwise of obtaining a wall biopsy at drainage. Operation theatre registry, operation log books and medical records at Aseer Central Hospital, Abha, Kingdom of Saudi Arabia, were reviewed to retrieve clinical details of the patients with pancreatic pseudocyst who required a drainage procedure in 13 years old period from August 1989 to November 2002. Sixteen patients were identified. Cyst wall biopsy was obtained in ten cases, in 8 of them the diagnosis was confirmed, while a true cyst was found in the remaining 2 excluding them further analysis. In the remaining 14 cases (8 males, 6 females, mean age 38 years, range 4-60), pain was the main presenting feature. Open internal damage was offered to 12 cases while one patient received external drainage under ultrasound guidance and the other received open external drainage. The type of operation was cystogastromy in 9 patients and cystojejunostomy in 3 patients. The recurrance rate after internal drainage was 16.7% while after external drainage was 100%. a procedure related complication occurred in 3 (21.4%) patients. The mortality, morbidity and recurrence rates in this series are compared favorably with other reports. The final diagnosis of a presumed pancreatic pseudocyst should rest on the histopathologic examination of the cyst wall. (author)

    To investigate the methods and effectiveness of one-stage operation for pelvis and acetabular fractures combined with Morel-Lavallée injury by internal fixation associated with vacuum sealing drainage (VSD). Between June 2008 and October 2012, 15 cases of pelvis and acetabular fractures combined with Morel-Lavallée injury were treated. There were 5 males and 10 females, aged from 18 to 67 years (mean, 36.8 years). Fractures were caused by traffic accident in 11 cases and crashing injury of heavy object in 4 cases. The time from injury to hospitalization was 3 hours to 9 days (mean, 5.4 days). Morel-Lavallée injury located in the above posterior superior iliac spine in 4 cases, greater trochanter in 7 cases, and anterior proximal thigh in 4 cases. In 10 cases complicated by pelvic fracture, there were 1 case of anteroposterior compression type, 3 cases of lateral compression type, 5 cases of vertical shear type, and 1 case of compound injury type; in 5 cases complicated by acetabular fracture, there were 1 case of transverse fracture, 1 case of posterior wall and posterior column fracture, 1 case of transverse acetabulum plus posterior wall fracture, and 2 cases of both columns fracture. Open reduction and internal fixation were used to treat pelvic and acetabular fractures, and VSD to treat Morel-Lavallée injury. When the drainage volume was less than 20 mL/d, interrupted wound suture or free skin grafting was performed. The hospitalization time was 16-31 days (mean, 20.8 days). Thirteen cases were followed up 4-16 months (mean, 7.8 months). The healing time of Morel-Lavallée injury was 16-36 days after operation (mean, 21.3 days). All the wounds had primary healing, and no infection occurred. The X-ray films showed that all fractures healed, with a mean healing time of 13.6 weeks (range, 11-18 weeks). At 6.5 months after operation, according to Majeed function scoring system in 8 cases of pelvic fracture, the results were excellent in 5 cases, good in 2 cases

    An experience of studying abroad or of academic exchange, really adds value to the professional and personal development of exchange students. This report aims to describe a student's experience in an international academic mobility program. It was developed from 2008 to 2009 in Brazil and Spain. The experiences, observations and activities of the student were emphasized believing that the training of students and researchers is not only restricted to the university and the students' home country, and that it is important to have possibilities of new experiences and differentiated knowledge. The conclusion is that this opportunity promoted a profound effect on psychological, cultural social and scientific development of the exchange student.

  9. Tourism and international business: The theoretical approach and practical experiences

    2011-01-01

    Full Text Available The paper discusses the relationships between tourism and international business. The research is based upon combining various theoretical concepts, significant empirical experiences and own attitudes of the authors. The key conclusion of the paper is that, despite of the partial progress in understanding tourism businesses, the relationships between tourism and international business need additional stimulus. In other words, more complete research in the related domains is needed in future. Any understanding of tourism is inadequate without appreciating the contributions that international business might bring, yet at the same time international business is incomplete in its coverage of international trade unless tourism is considered. The consumption-driven agenda of much tourism research has been favoured over supply-side discourses of the production process it self. That is why the role of major transnational companies, setting the trends that other types of firms in the tourism sector follow is focused in the paper.

    The inauguration of the cooler synchrotron COSY Juelich was celebrated on April 1st, 1993. After the first successful acceleration to proton momenta above 800 GeV/c, beamtimes for experiments were scheduled in parallel to further machine development. The first experiment was the internal target experiment EDDA, which investigated the energy dependence of the p-p interaction. It makes use of a 3x4 μm 2 thin CH 2 fiber as an internal target. The thickness of the fiber is more than adequate to achieve high luminosities, so the intensity of the stored beam has to be reduced to 10 7 p. On the other hand, it is thin enough to achieve beam lifetimes of 3 s at 1.4 GeV/c. Details of the target fabrication and the first experimental results will be discussed. Both external experimental facilities at COSY, the time-of-flight spectrometer, and the magnetic spectrometer BIG KARL use a liquid hydrogen (deuterium) target. The first experiments were carried out at proton energies between 300 MeV and 500 MeV. Also, these experimental data will be presented. Two further internal experiments are prepared for the installation into the COSY ring. The target for the first experiment is a gas-jet target, the second experiment uses ribbon targets for the interaction. The status of both experimental setups will be shown. (orig.)

    , the water-table oscillation was monitored using 2.5-m depth observation wells, during one year. The studied Oxisols were considered chemically and physically similar. However, they differed as to morphological and mineralogical characterization, with the presence of concretionary horizons and goethite in the LVA. Goethite stability in this soils was influenced by the water-table oscillation. The presence of concretionry horizons in LVA caused an internal drainage deficiency, which resulted in lower saturated hydraulic conductivity and lower variation of the water-table levels. Therefore, LVA soils show lower agricultural potential than LV ones, in Distrito Federal. Oxisols physicohydric characteristics have little influence on soil diagnostic attributes, except for iron oxides mineralogy, which show increased contents of goethite in low internal drainage conditions.

  13. Percutaneous biliary drainage and stenting

    Full text: Percutaneous transhepatic cholangiography (PTC) is an X-ray or US guided procedure that involves the injection of a contrast material directly into the bile ducts inside the liver to produce pictures of them. If a blockage or narrowing is found, additional procedures may be performed: 1. insertion of a catheter to drain excess bile out of the body or both - internal and external; 2. plastic endoprothesis placement; 3. self-expandable metal stents placement to help open bile ducts or to bypass an obstruction and allow fluids to drain. Current percutaneous biliary interventions include percutaneous transhepatic cholangiography (PTC) and biliary drainage to manage benign and malignant obstructions. Internal biliary stents are either plastic or metallic, and various types of each kind are available. Internal biliary stents have several advantages. An external tube can be uncomfortable and have a psychological disadvantage. An internal stent prevents the problems related to external catheters, for example, pericatheter leakage of bile and the need for daily flushing. The disadvantages include having to perform endoscopic retrograde cholangiopancreatography (ERCP) or new PTC procedures to obtain access in case of stent obstruction. Better patency rates are reported with metallic than with plastic stents in cases of malignant obstruction, though no effect on survival is noted. Plastic internal stents are the cheapest but reportedly prone to migration. Metallic stents are generally not used in the treatment of benign disease because studies have shown poor long-term patency rates. Limited applications may include the treatment of patients who are poor surgical candidates or of those in whom surgical treatment fails. Most postoperative strictures are treated surgically, though endoscopic and (less commonly) percutaneous placement of nonmetallic stents has increasingly been used in the past few years. Now there are some reports about use of biodegradable biliary

    Endoscopic management of post-Whipple pancreatic adverse events (AEs) with enteroscopy-assisted endoscopic retrograde pancreatography (e-ERP) is associated with high failure rates. EUS-guided pancreatic duct drainage (EUS-PDD) has shown promising results; however, no comparative data have been done for these 2 modalities. The goal of this study is to compare EUS-PDD with e-ERP in terms of technical success (PDD through dilation/stent), clinical success (improvement/resolution of pancreatic-type symptoms), and AE rates in patients with post-Whipple anatomy. This is an international multicenter comparative retrospective study at 7 tertiary centers (2 United States, 2 European, 2 Asian, and 1 South American). All consecutive patients who underwent EUS-PDD or e-ERP between January 2010 and August 2015 were included. In total, 66 patients (mean age, 57 years; 48% women) and 75 procedures were identified with 40 in EUS-PDD and 35 in e-ERP. Technical success was achieved in 92.5% of procedures in the EUS-PDD group compared with 20% of procedures in the e-ERP group (OR, 49.3; P procedures in the EUS-PDD group compared with 23.1% in the e-ERP group (OR, 23.3; P Procedure time and length of stay were not significantly different between the 2 groups. EUS-PDD is superior to e-ERP in post-Whipple anatomy in terms of efficacy with acceptable safety. As such, EUS-PDD should be considered as a potential first-line treatment in post-pancreaticoduodenectomy anatomy when necessary expertise is available.

    The Criticality Safety Benchmark Evaluation Project (CSBEP) was initiated in 1992 by the United States Department of Energy. The project quickly became an international effort as scientists from other interested countries became involved. The International Criticality Safety Benchmark Evaluation Project (ICSBEP) is now an official activity of the Organization for Economic Cooperation and Development-Nuclear Energy Agency (OECD-NEA). 'International Handbook of Criticality Safety Benchmark Experiments' was prepared and is updated year by year by the working group of the project. This handbook contains criticality safety benchmark specifications that have been derived from experiments that were performed at various nuclear critical facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate calculation techniques used. The author briefly introduces the informative handbook and would like to encourage Japanese engineers who are in charge of nuclear criticality safety to use the handbook. (author)

    Water flowing from underground and surface mines and contains high concentrations of dissolved metals is called mine drainage. Mine drainage can be categorized into several basic types by their alkalinity or acidity. Sulfide rich and carbonate poor materials are expected to produce acidic drainage, and alkaline rich materials, even with significant sulfide concentrations, often produce net alkaline water. Mine drainages are dangerous because pollutants may decompose in the environment. In...

    The Italian experience in the organization of transplantation procedures could represent a relevant example of an internal development at a national level, combined with a strengthening of international collaborations. These results can be attributed first to the creation of the Italian National Transplant Centre (Centro Nazionale Trapianti [CNT]), and then to an ongoing European process that is leading to a greater awareness of the importance of closer collaboration between the organizations already existing and operating in the field of transplantation. This article summarizes the role and the most significant achievements of the CNT. Copyright © 2011. Published by Elsevier Inc.

    2012-04-24

    Service learning and study abroad opportunities have become increasingly popular in nursing education in the past decade. The purpose of this systematic review was to explore existing literature concerning global health experiences in nursing education. Twenty-three empirical articles from 2003 to 2010 were reviewed, building upon existing reviews of international nursing education literature. Research on two-way exchange experiences and models for best practice were found to be lacking. While an array of countries were represented as the visiting or hosting side of the experience, few co-authors from host countries were found, particularly in literature originating from the U.S. The authors recommend that two-way exchange programs be evaluated to identify successful strategies and barriers to success. Ongoing evaluation of exchanges is necessary to ensure continued sustainable partnership and exchange in immersion experiences for nursing students.

    Full Text Available The article examines the market of leasing relations in the UK, Germany, France, the USA. Comparative analysis of development of leasing in foreign countries has been carried out in order to use international experience of leasing relations in Ukraine at the present stage of development of state economy. In spite of prevalence of leasing in developed countries, this kind of relationship is still uncommon in the economic environment of Ukraine because of its novelty and lack of experience. Relevance of leasing development in Ukraine, including the formation of leasing market, primarily is caused by a significant proportion of obsolete equipment and low efficiency of its use. One of solutions to these problems can be leasing which brings together all the elements of international trade, credit, and investment operations.

    The International Reactor Physics Experiment Evaluation (IRPhE) Project aims to provide the nuclear community with qualified benchmark data sets by collecting reactor physics experimental data from nuclear facilities, worldwide. More specifically the objectives of the expert group are as follows: - maintaining an inventory of the experiments that have been carried out and documented; - archiving the primary documents and data released in computer-readable form; - promoting the use of the format and methods developed and seek to have them adopted as a standard. For those experiments where interest and priority is expressed by member countries or working parties and executive groups within the NEA provide guidance or co-ordination in: - compiling experiments into a standard international agreed format; - verifying the data, to the extent possible, by reviewing original and subsequently revised documentation, and by consulting with the experimenters or individuals who are familiar with the experimenters or the experimental facility; - analysing and interpreting the experiments with current state-of-the-art methods; - publishing electronically the benchmark evaluations. The expert group will: - identify gaps in data and provide guidance on priorities for future experiments; - involve the young generation (Masters and PhD students and young researchers) to find an effective way of transferring know-how in experimental techniques and analysis methods; - provide a tool for improved exploitation of completed experiments for Generation IV reactors; - coordinate closely its work with other NSC experimental work groups in particular the International Criticality Safety Benchmark Evaluation Project (ICSBEP), the Shielding Integral Benchmark Experiment Data Base (SINBAD) and others, e.g. knowledge preservation in fast reactors of the IAEA, the ANS Joint Benchmark Activities; - keep a close link with the working parties on scientific issues of reactor systems (WPRS), the expert

    Student coaches undertake internships to develop practical skills and gain experience to improve employability prospects. The characteristics of the coaches who undertake these internships, their experiences and the nature of the work being performed are currently unknown. The purpose of this study was to report the characteristics of strength and conditioning (S&C) coaches who have undertaken internships and their experiences during their respective placements. A total of 113 men and 6 women completed an online survey. Placements generally lasted 6-12 months (66%), were unpaid (93%) and took place at professional teams (63%). All respondents had a standard of experience prior to commencement (82%); a higher-education degree (bachelor's degree 56%; master's degree 18%) and others were qualified S&C coaches (16%). Activities consisted largely of coaching (47%), data collection (22%) and equipment set-up (25%) but lacked provision of appropriate training. Mentors were allocated to interns; however, often developmental objectives were not discussed, meetings were rarely documented, and in some cases, no meetings took place. This study suggests that internships offer worthwhile experiences and assistance in skill development to progress in S&C. However, clearer guidelines are required to define the responsibilities of employers and interns, to maximise these experiential learning opportunities and avoid the exploitation of willing students.

  20. Vibration behavior of PWR reactor internals Model experiments and analysis

    Assedo, R.; Dubourg, M.; Livolant, M.; Epstein, A.

    1975-01-01

    In the late 1971, the CEA and FRAMATOME decided to undertake a comprehensive joint program of studying the vibration behavior of PWR internals of the 900 MWe, 50 cycle, 3 loop reactor series being built by FRAMATOME in France. The PWR reactor internals are submitted to several sources of excitation during normal operation. Two main sources of excitation may effect the internals behavior: the large flow turbulences which could generate various instabilities such as: vortex shedding: the pump pressure fluctuations which could generate acoustic noise in the circuit at frequencies corresponding to shaft speed frequencies or blade passing frequencies, and their respective harmonics. The flow induced vibrations are of complex nature and the approach selected, for this comprehensive program, is semi-empirical and based on both theoretical analysis and experiments on a reduced scale model and full scale internals. The experimental support of this program consists of: the SAFRAN test loop which consists of an hydroelastic similitude of a 1/8 scale model of a PWR; harmonic vibration tests in air performed on full scale reactor internals in the manufacturing shop; the GENNEVILLIERS facilities which is a full flow test facility of primary pump; the measurements carried out during start up on the Tihange reactor. This program will be completed in April 1975. The results of this program, the originality of which consists of studying separately the effects of random excitations and acoustic noises, on the internals behavior, and by establishing a comparison between experiments and analysis, will bring a major contribution for explaining the complex vibration phenomena occurring in a PWR

    Many tonnes of compost are generated per year due to door step composting of both garden and kitchen waste. Whilst there are commercial outlets for the finer grade of compost (25 mm). This paper reports part of a WRAP-sponsored (Waste Resources Action Programme) study which investigated the potential for green (GC) and mixed green and food (MC) composts to be incorporated into Sustainable Drainage (SUDS) devices such as swales, and replace the topsoil (TS) onto which turf is laid or grass seed distributed. However, it is not known whether compost can replace TS in terms of pollutant remediation, both the trapping of polluted particulates and in dealing with hydrocarbons such as oil, but also from a biofilm development and activity perspective. Using laboratory based experiments utilising leaching columns and an investigation of microbiological development in the composts studied, it was found that many of the differences in performance between MC and GC were insignificant, whilst both composts performed better in terms of pollutant retention than TS. Mixed compost in particular could be used in devices where there may be oil spillages, such as the lorry park of a Motorway Service Area due to its efficiency in degrading oil. Samples of GC and MC were found to contain many of the bacteria and fungi necessary for an active and efficient biofilm which would be an argument in their favour for replacement of TS and incorporation in swales.

    1997-11-01

    In order to extend our understanding of the thermally driven atmospheric winds and their influence on pollutant transport, a hot air balloon experiment was conducted over a four day period in June, 1997 near Nogales, Arizona. The focus was on the early morning break-up of the stable down-slope and down-valley flow and the establishment of a convective boundary layer near the surface in the absence of synoptic winds. Temperature, elevation, position and particulate matter concentration were measured aloft and temperature gradient and wind velocity were measured at ground level. The wind velocity within the stable layer was generally less than 1.5 m/s. Just above the stable layer (about 300 meters above the valley) the wind shifted leading to an erosion of the stable layer from above. Surface heating after sunrise created a convective layer which rose from the ground until the stable layer was destroyed. Examples of temperature fluctuation measurements at various elevations during the establishment of the convective flow will be presented. Implications of results for turbulence parameterizations needed for numerical models of wind fields in complex terrain will be discussed.

  7. WATER DRAINAGE MODEL

    International Nuclear Information System (INIS)

    Case, J.B.

    2000-01-01

    The drainage of water from the emplacement drift is essential for the performance of the EBS. The unsaturated flow properties of the surrounding rock matrix and fractures determine how well the water will be naturally drained. To enhance natural drainage, it may be necessary to introduce engineered drainage features (e.g. drilled holes in the drifts), that will ensure communication of the flow into the fracture system. The purpose of the Water Drainage Model is to quantify and evaluate the capability of the drift to remove water naturally, using the selected conceptual repository design as a basis (CRWMS M andO, 1999d). The analysis will provide input to the Water Distribution and Removal Model of the EBS. The model is intended to be used to provide postclosure analysis of temperatures and drainage from the EBS. It has been determined that drainage from the EBS is a factor important to the postclosure safety case

    Internationally trained health professionals are an important part of the domestic workforce, but little is known about the working experiences of internationally trained pharmacists (ITPs) in Great Britain (GB). The purpose of this study is to explore the work experiences of ITPs practising in the community or hospital sector in GB. Twenty-five semi-structured, face-to-face interviews were conducted with a sample of European Economic Area (EEA) and non-EEA pharmacists who, at the time of the study, practised in the community (n = 20) or hospital sector (n = 5) in the North West England from March to May 2009. In general, ITPs complained about their heavy workload, long working hours and lack of support from their employers. Specifically, EEA pharmacists in most cases felt excluded from the professional network and sensed colleagues saw them as 'foreigners' while some non-EEA pharmacists had to deal with a level of hostility from patients. This novel research provides a foundation for future work on ITPs in GB and could assist employers to better target their efforts in development of standards to support the working experiences of ITPs in GB. © 2014 Royal Pharmaceutical Society.

    2018-01-01

    Tensiometer readings obtained at high resolution during drainage of structured soil columns revealed pressure jumps with long range correlations and burst sequences with a hierarchical structure. The statistical properties of jumps are similar to Haines jumps described in invasion percolation...... processes at pore scale, but they are much larger in amplitude and duration. Pressure jumps can result from transient redistribution of water potential in internal regions of soil and can be triggered during drainage by capillary displacements at the scale of structural pores....

  10. ICSBEP-2007, International Criticality Safety Benchmark Experiment Handbook

    International Nuclear Information System (INIS)

    Blair Briggs, J.

    2007-01-01

    1 - Description: The Critically Safety Benchmark Evaluation Project (CSBEP) was initiated in October of 1992 by the United Sates Department of Energy. The project quickly became an international effort as scientist from other interested countries became involved. The International Criticality Safety Benchmark Evaluation Project (ICSBEP) is now an official activity of the Organization of Economic Cooperation and Development - Nuclear Energy Agency (OECD-NEA). This handbook contains criticality safety benchmark specifications that have been derived from experiments that were performed at various nuclear critical facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate calculational techniques used to establish minimum subcritical margins for operations with fissile material. The example calculations presented do not constitute a validation of the codes or cross section data. The work of the ICSBEP is documented as an International Handbook of Evaluated Criticality Safety Benchmark Experiments. Currently, the handbook spans over 42,000 pages and contains 464 evaluations representing 4,092 critical, near-critical, or subcritical configurations and 21 criticality alarm placement/shielding configurations with multiple dose points for each and 46 configurations that have been categorized as fundamental physics measurements that are relevant to criticality safety applications. The handbook is intended for use by criticality safety analysts to perform necessary validations of their calculational techniques and is expected to be a valuable tool for decades to come.

    1987-01-01

    Over the past 4 years, 55 cases (one transudate, 28 exudates, and 26 empymas) were drained. Surgical chest tubes alone were used in 35 drainages, percutaneous catheters alone in five drainages, and both types in 15 drainages. Percutaneous catheter drainage was successful in 12 of 20 drainages (60%). Surgical tube drainage was successful in 18 of 50 drainages (36%). The success rate for the nonempyema group was 45% with both types of drainage. For the empyema group, the success rate for percutaneous catheter drainage was 66% vs 23% for surgical tube drainage. Seven major complications occurred with surgical tube drainage, but only one major complication occurred with percutaneous catheter drainage. Radiologically guided percutaneous catheter drainage should be the procedure of choice for pleural fluid drainage. It has a higher success rate for empyemas and is associated with less complications

    2015-11-01

    This article examines the intersecting roles of gender, ethnicity, and professional status in shaping the experiences of internationally educated health professionals in Canada. The article is based on 140 semi-structured qualitative interviews with internationally trained nurses and physicians who came to Canada within past 10 years with the intention to practice their profession. Describing the challenging process of professional integration in Canada, our participants highlighted incidents of discrimination they experienced along the way. Although some of the participants from both professional groups experienced racial discrimination, the context of those experiences differed. Physicians rarely reported instances of discrimination in communication with patients or nurses. Instead, they were concerned with instances of discrimination within their own professional group. Nurses, on the other hand, reported discrimination at the hands of patients and their families as well as racialization by physicians, management, and other nurses. We conclude our article with a reflection on the role that gender and professional status play in shaping the experiences of ethnic discrimination of internationally educated health professionals. © The Author(s) 2015.

    2013-01-01

    For the past decade participation in service and experiential learning in higher education has increased. The purpose of this study was to explore the lived experience of BSN and MSN students participating in a multidisciplinary service-learning course in a rural, underserved village in Belize. Researchers analyzed student journals utilizing qualitative data analysis techniques. There were eight consistent themes found in the student journals. The findings indicate that international service learning opportunities increase students' awareness of their place in a global society and the potential contribution they can make in society. For the past decade, service and experiential learning in higher education, including nursing education, has become increasingly important. Simply put, service and experiential learning combine community service activities with a student's academic study for the sole purpose of enriching the academic experience. As faculty, we feel the goal of baccalaureate and graduate nursing education is to produce an educated professional who will become a responsible citizen.

    1998-09-01

    This publication gives a survey of economic theory and international experience connected to electricity spot markets. The main purpose is to consider the attempts that have been made to apply economic theory and empirical methods to the analysis of electricity markets, and to evaluate them in light of theoretical considerations and empirical evidence. The publication describes in simple terms the basic pool pricing mechanism, and experience with pools in a number of countries. It is worth emphasizing that it is not the purpose to treat in extensive detail the structure of electricity pools around the world. Key factors of the markets in England and Wales, Norway and Australia are described in order to allow for a comparison of design issues and evaluation of competitive performance. 80 refs., 14 figs., 15 tabs.

  18. A Burning Plasma Experiment: the role of international collaboration

    2003-04-01

    The world effort to develop fusion energy is at the threshold of a new stage in its research: the investigation of burning plasmas. A burning plasma is self-heated. The 100 million degree temperature of the plasma is maintained by the heat generated by the fusion reactions themselves, as occurs in burning stars. The fusion-generated alpha particles produce new physical phenomena that are strongly coupled together as a nonlinear complex system, posing a major plasma physics challenge. Two attractive options are being considered by the US fusion community as burning plasma facilities: the international ITER experiment and the US-based FIRE experiment. ITER (the International Thermonuclear Experimental Reactor) is a large, power-plant scale facility. It was conceived and designed by a partnership of the European Union, Japan, the Soviet Union, and the United States. At the completion of the first engineering design in 1998, the US discontinued its participation. FIRE (the Fusion Ignition Research Experiment) is a smaller, domestic facility that is at an advanced pre-conceptual design stage. Each facility has different scientific, programmatic and political implications. Selecting the optimal path for burning plasma science is itself a challenge. Recently, the Fusion Energy Sciences Advisory Committee recommended a dual path strategy in which the US seek to rejoin ITER, but be prepared to move forward with FIRE if the ITER negotiations do not reach fruition by July, 2004. Either the ITER or FIRE experiment would reveal the behavior of burning plasmas, generate large amounts of fusion power, and be a huge step in establishing the potential of fusion energy to contribute to the world's energy security.

    The Compressed Baryonic Matter (CBM) experiment is a part of the Facility for Antiproton and Ion Research (FAIR) in Darmstadt at GSI. In CBM experiment a precisely time synchronized fault tolerant self-triggered electronics is required for Data Acquisition (DAQ) system in CBM experiments which can support high data rate (up to several TB/s). As a part of the implementation of the DAQ system of Muon Chamber (MUCH) which is one of the important detectors in CBM experiment, a FPGA based Gigabit Transceiver (GBTx) emulator is implemented. Readout chain for MUCH consists of XYTER chips (Front end electronics) which will be directly connected to detector, GBTx emulator, Data Processing Board (DPB) and First level event selector board (FLIB) with backend software interface. GBTx emulator will be connected with the XYTER emulator through LVDS (Low Voltage Differential Signalling) line in the front end and in the back end it is connected with DPB through 4.8 Gbps optical link. IPBus over Ethernet is used for internal monitoring of the registers within the GBTx. In IPbus implementation User Datagram Protocol (UDP) stack is used in transport layer of OSI model so that GBTx can be controlled remotely. A Python script is used at computer side to drive IPbus controller.

The benchmark specifications are intended for use by criticality safety engineers to validate calculational techniques used to establish minimum subcritical margins for operations with fissile material and to determine criticality alarm requirement and placement. Many of the specifications are also useful for nuclear data testing. Example calculations are presented; however, these calculations do not constitute a validation of the codes or cross section data. The evaluated criticality safety benchmark data are given in nine volumes. These volumes span over 55,000 pages and contain 516 evaluations with benchmark specifications for 4,405 critical, near critical, or subcritical configurations, 24 criticality alarm placement / shielding configurations with multiple dose points for each, and 200 configurations that have been categorized as fundamental physics measurements that are relevant to criticality safety applications. Experiments that are found unacceptable for use as criticality safety benchmark experiments are discussed in these evaluations; however, benchmark specifications are not derived for such experiments (in some cases models are provided in an appendix). Approximately 770 experimental configurations are categorized as unacceptable for use as criticality safety benchmark experiments. Additional evaluations are in progress and will be

    2013-11-01

    Short-term, study-abroad, elective engineering courses were developed in order to raise the international awareness and global competency of engineering students. These Compact International Experience (CIE) courses were taught in response to a strong student desire for engineering study abroad courses and an effort by the home institution to internationalize its curriculum. An assessment of repeat offerings of two three-semester-unit courses on Topics in Fluid Mechanics and Advanced Electronic Circuit Design in a three-week time frame in France and Australia was performed. The goals of the two CIE courses are an effective teaching of their respective technical content as well as a student understanding of the cultural environment and the impact of engineering solutions from a global and societal viewpoint. In the repeat offerings, increased interaction with local industry was an additional goal. The CIE courses were assessed through surveys completed at the beginning and end of the courses, weekly student reflection papers, course evaluations, and formalized instructor observations. Based on the assessment performed, the two CIE courses have been found to be a valuable approach in the delivery of engineering technical electives combined with an international experience.

    There is a long history of the microbe-collection experiments at high altitude. Microbes have been collected using balloons, aircraft and meteorological rockets from 1936 to 1976. Spore forming fungi and Bacilli, and Micrococci have been isolated in these experiments. It is not clear how high do microbes go up. If the microbes might have been present even at higher altitudes, the fact would endorse the possibility of interplanetary migration of life. TANPOPO, dandelion, is the name of a grass whose seeds with floss are spread by the wind. We propose the analyses of interplanetary migration of microbes, organic compounds and meteoroids on Japan Experimental Module (JEM) of the International Space Station (ISS). Ultra low-density aerogel will be used to capture micrometeoroid and debris. Particles captured by aerogel will be used for several analyses after the initial inspection of the gel and tracks. Careful analysis of the tracks in the aerogel will provide the size and velocity dependence of debris flux. The particles will be analyzed for mineralogical, organic and microbiological characteristics. Aerogels are ready for production in Japan. Aerogels and trays are space proven. All the analytical techniques are ready. The Tanpopo mission was accepted as a candidate experiments on Exposed Facility of ISS-JEM.

    2017-12-01

    Full Text Available The article is aimed at generalizing the international experience of regional development of creative industries and defining directions of its implementation in Ukraine. The experience of the world countries on regional development of creative industries has been generalized, tendencies and specificity of these development processes have been identified. The interrelation of the process of development of creative industries with innovation development of regions has been defined. Prospects for development of creative industries in regions of Ukraine have been identified and directions of implementation of foreign experience have been suggested. Thus, strategic measures for the development of creative clusters can be the corresponding priorities of cultural policy in the regions, the development of specific projects and programs, the opening of art-incubators, the creation of a favorable investment climate, financial and tax incentives as conditions for interaction between creativity and business. The scale and dynamics of the world’s creative sector, which has a significant potential for growth and less vulnerability in financial-economic crises compared to the traditional sector, gives chance to high expectations for the development of creative industries in Ukraine as well.

  6. Benthic metal fluxes and sediment diagenesis in a water reservoir affected by acid mine drainage: A laboratory experiment and reactive transport modeling

    Reservoirs are one of the primary water supply sources. Knowledge of the metal fluxes at the water-sediment interfaces of reservoirs is essential for predicting their ecological quality. Redox oscillations in the water column are promoted by stratification; turnover events may significantly alter metal cycling, especially in reservoirs impacted by acid mine drainage (AMD). To study this phenomenon, an experiment was performed under controlled laboratory conditions. Sediment cores from an AMD-affected reservoir were maintained in a tank with reservoir water for approximately two months and subjected to alternating oxic-hypoxic conditions. A detailed metal speciation in solid phases of the sediment was initially performed by sequential extraction, and pore water was analyzed at the end of each redox period. Tank water metals concentrations were systematically monitored throughout the experiment. The experimental results were then used to calibrate a diffusion-reaction model and quantify the reaction rates and sediment-water fluxes. Under oxic conditions, pH, Fe and As concentrations decreased in the tank due to schwertmannite precipitation, whereas the concentrations of Al, Zn, Cu, Ni, and Co increased due to Al(OH)3 and sulfide dissolution. The reverse trends occurred under hypoxic conditions. Under oxic conditions, the fluxes calculated by applying Fick’s first law to experimental concentration gradients contradicted the fluxes expected based on the evolution of the tank water. According to the reactive transport calculations, this discrepancy can be attributed to the coarse resolution of sediment sampling. The one-cm-thick slices failed to capture effectively the notably narrow (1-2 mm) concentration peaks of several elements in the shallow pore water resulting from sulfide and Al(OH)3 dissolution. The diffusion-reaction model, extended to the complete year, computed that between 25% and 50% of the trace metals and less than 10% of the Al that precipitated under

    Compassion is considered the cornerstone of nursing practice. However, the recent failures in delivering high-quality compassionate nursing care in the UK's National Health Service have brought the topic of compassion to the attention of the public, service providers, policy makers and academics. The aim of this study was to explore the nurses' views and experiences of a number of compassion-related issues in nursing and describe similarities and differences at an international level as well as from the different nursing roles of the participating nurses. An exploratory, cross-sectional descriptive study, using the International Online Compassion Questionnaire. A total of 1323 nurses from 15 countries completed the questionnaire. The majority of participants (59.5%) defined compassion as "Deep awareness of the suffering of others and wish to alleviate it" but definitions of compassion varied by country. Of participants, 69.6% thought compassion was very important in nursing and more than half (59.6%) of them argued that compassion could be taught. However, only 26.8% reported that the correct amount and level of teaching is provided. The majority of the participants (82.6%) stated that their patients prefer knowledgeable nurses with good interpersonal skills. Only 4.3% noted that they are receiving compassion from their managers. A significant relationship was found between nurses' experiences of compassion and their views about teaching of compassion. Our study is unique in identifying the views and experiences of nurses from 15 different countries worldwide. The findings reveal that compassion is neither addressed adequately in nursing education nor supported in the practice environment by managers. Self-report bias was inherent to our survey study design. Furthermore, the individual cultural differences and similarities in the findings are difficult to extrapolate owing to the fact that our analysis was at country level, as well as at the level of the

    International exchange training in genetic counseling is increasing, but research examining these experiences is lacking. In this study 309 genetic counseling students and genetic counselors completed an anonymous survey investigating six major research questions: (1) How prevalent are international genetic counseling experiences? (2) What types are pursued and why? (3) What supports and barriers exist? 3) What are the demographic characteristics of individuals accruing international experience? (5) Does international experience promote professional development? and (6) Do genetic counseling students and professionals perceive international experiences as beneficial? Most respondents were Caucasian females born in one of 25 countries. The most prevalent experiences involved either clinical observation or clinical training. Common motivations for pursuing international experience were personal growth, exposure to a different healthcare system, and travel opportunities. Outcomes included professionally-relevant experience and personal growth. Barriers included finances, limited availability of opportunities, and for those without international experience, family responsibilities. Additional findings, practice and training implications, and research recommendations are provided.

    2004-01-01

    The OECD/NEA Nuclear Science Committee (NSC) has identified the need to establish international databases containing all the important experiments that are available for sharing among the specialists and has set up or sponsored specific activities to achieve this. The aim is to preserve them in an agreed standard format in computer accessible form, to use them for international activities involving validation of current and new calculational schemes including computer codes and nuclear data libraries, for assessing uncertainties, confidence bounds and safety margins, and to record measurement methods and techniques. It is a significant saving results from disseminating a standard benchmark set to be used worldwide. A framework for professionals that use the standard benchmark set to validate and verify modeling codes and data for radiation transport, criticality safety and reactor physics applications guarantees a comparative set of analyses. It represents also a good basis for pinpointing important gaps and where efforts should be concentrated and ensures knowledge and competence preservation, management and transfer in nuclear science and engineering. A large number of experimentalists, physicists, evaluators, modelers have devoted large amounts of their efforts and competencies to produce the data on which the methods we are using today are based. These data are far from having been exploited fully for the different nuclear and radiation technologies. This wealth of information needs to be preserved in a form more easily exploitable by modern information technology and for use in connection with novel and refined computational models with limitations of the past removed. These data will form the basis for the studies of more advanced nuclear technology, will be instrumental in identifying areas where there is a lack of knowledge and thus provide support to justifying new experiments that would reduce design uncertainties and consequently costs.

    Full text: In 2008 the University of Groningen has ten years of experience with the system of complex broad licences. This system was introduced on a larger scale in the Netherlands in the last decade of the twentieth century. Its main characteristics are an internal radiation protection organization and a system of internal permits or licences for all applications of ionizing radiation along with periodical inspections. Since 1998/9 we yearly conduct inspections of all users of ionizing radiation within the University of Groningen. In our presentation we will discuss the general scheme for these inspections as well as the development of its results over the past decade. Following a period of habituation the last few years show a adequate and continuous level of radiation protection. It is also concluded that continuation of the inspection projects is a prerequisite to preserve this situation. Combined with the inspection project of 2007 an informal study of the 'customer'-satisfaction with respect to various aspects of the radiation protection organization was performed. Our data were collected using a questionnaire filled out by local radiation safety officers. In this contribution detailed results of this investigation will be presented. Preliminary results show that the overall appreciation of the radiation protection organization is qualified as 'good'. (author)

    1995-01-01

    This paper provides an overview of the recent trend towards private ownership and financing of power projects in the developing countries, focusing on the role played by both private and public agencies in meeting the large financing challenges. The paper draws upon the operational experience of the International Finance Corporation, which has been involved in the financing of more than 30 private power projects in the developing countries over the past three decades. Among the issues that affect implementation of private power projects is the balancing of risk and reward to equity investors and to commercial lenders. The paper discusses the principal sources of risk and the strategies used to manage them. A related issue is the competition for capital on the international markets, and the techniques that are being devised to bring more finance to the power sector. Finally, the paper considers the role of government in bringing private investors to the power sector, and the approaches being adopted to balance the needs of investors with the needs of the public.

    Nursing leaders from six countries engaged in a year-long discussion on global leadership development. The purpose of these dialogues was to strengthen individual and collective capacity as nursing leaders in a global society. Field experiences in practice and education were shared. Perspectives on global leadership can strengthen nurses' contributions to practice, workplace and policy issues worldwide. Transformational leadership empowers nurses' increasing confidence. Mentoring is needed to stimulate leadership development but this is lacking in many settings where nurses practice, teach and influence policy. Organizations with global mission provide opportunity for nurses' professional growth in leadership through international dialogues. Dialogues among participants were held monthly by conference calls or videoconferences. Example stories from each participant illustrated nursing leadership in action. From these exemplars, concepts were chosen to create a framework. Emerging perspectives and leadership themes represented all contexts of practice, education, research and policy. The cultural context of each country was reflected in the examples. Themes emerged that crossed global regions and countries. Themes were creativity, change, collaboration, community, context and courage. Relationships initially formed in professional organizations can be extended to intentionally facilitate global nursing leadership development. Exemplars from the dialogues demonstrated nursing leadership in health policy development within each cultural context. Recommendations are given for infrastructure development in organizations to enhance future collaborations. © 2014 International Council of Nurses.

    Microgrids can provide an avenue for increasing the amount of distributed generation and delivery of electricity, where control is more dispersed and quality of service is locally tailored to end-use requirements. Much of this functionality is very different from the predominant utility model to date of centralized power production which is then transmitted and distributed across long distances with a uniform quality of service. This different functionality holds much promise for positive change, in terms of increasing reliability, energy efficiency, and renewable energy while decreasing and carbon emissions. All of these functions should provide direct cost savings for customers and utilities as well as positive externalities for society. As we have seen from the international experience, allowing microgrids to function in parallel with the grid requires some changes in electricity governance and incentives to capture cost savings and actively price in positive externalities. If China can manage to implement these governance changes and create those incentive policies, it will go beyond the establishment of a successful microgrid demonstration program and become an international leader in microgrid deployment.

    Percutaneous transhepatic biliary drainage was successfully made 20 times on 17 patients of obstructive jaundice for recent 1 year since June 1981 at Department of Radiology in Seoul National University Hospital. The causes of obstructive jaundice was CBD Ca in 13 cases, metastasis in 2 cases, pancreatic cancer in 1 case and CBD stone in 1 case. Percutaneous transhepatic biliary drainage is a relatively ease, safe and effective method which can be done after PTC by radiologist. It is expected that percutaneous transhepatic biliary drainage should be done as an essential procedure for transient permanent palliation of obstructive jaundice

    2002-01-01

    The international muon ionization cooling experiment MICE will consist of two focusing cooling cells and a pair of uniform field solenoids used for particle identification and emittance measurements. The 2.75-meter long cooling cells have a pair of field flip coils and a coupling coil. The 0.52-meter diameter field flip coils surround an absorber that removes transverse and longitudinal momentum from the muons to be cooled. The beam in the absorber is at a minimum beta point so that scattering of the muons is minimized. The 1.7-meter diameter coupling coils are outside of conventional 201.25 MHz RF cavities that accelerate the muons putting longitudinal momentum into the muons without putting back the transverse momentum into the beam. A third set of flip coils helps the muon beam transition from and to the experimental solenoids. The 0.6-meter diameter experimental solenoids have a uniform field region (good to about 1 part in 1000) that is 1.3-meters long. The MICE experiment magnets must operate as a single unit so that the field profile will produce the maximum muon cooling

    This paper reports that international safeguards have been applied in Sweden since the early 70s. Experiences have been achieved from exclusive bilateral and trilateral control followed by NPT safeguards in 1975. The Swedish State System for accountancy and Control (SSAC) includes all regulations that follows from prevailing obligations regarding the peaceful uses of nuclear material. The system has been developed in cooperation between the national authority, the Swedish Nuclear Power Inspectorate (SKI) and the Swedish nuclear industry. The paper presents experiences from the practical implementation of the SSAC and the IAEA safeguards system, gained by the SKI and the nuclear industry, respectively. Joint approaches and solutions to some significant safeguards issues are presented. The cooperation between the nuclear industry and the authority in R and D activities, in particular with respect to the Swedish Support Program is highlighted, e.g. the use of nuclear facilities in development or training tasks. some of the difficulties encountered with the system are also touched upon

  1. Virtual Reality Simulation of the International Space Welding Experiment

    Phillips, James A.

    1996-01-01

    Virtual Reality (VR) is a set of breakthrough technologies that allow a human being to enter and fully experience a 3-dimensional, computer simulated environment. A true virtual reality experience meets three criteria: (1) It involves 3-dimensional computer graphics; (2) It includes real-time feedback and response to user actions; and (3) It must provide a sense of immersion. Good examples of a virtual reality simulator are the flight simulators used by all branches of the military to train pilots for combat in high performance jet fighters. The fidelity of such simulators is extremely high -- but so is the price tag, typically millions of dollars. Virtual reality teaching and training methods are manifestly effective, and we have therefore implemented a VR trainer for the International Space Welding Experiment. My role in the development of the ISWE trainer consisted of the following: (1) created texture-mapped models of the ISWE's rotating sample drum, technology block, tool stowage assembly, sliding foot restraint, and control panel; (2) developed C code for control panel button selection and rotation of the sample drum; (3) In collaboration with Tim Clark (Antares Virtual Reality Systems), developed a serial interface box for the PC and the SGI Indigo so that external control devices, similar to ones actually used on the ISWE, could be used to control virtual objects in the ISWE simulation; (4) In collaboration with Peter Wang (SFFP) and Mark Blasingame (Boeing), established the interference characteristics of the VIM 1000 head-mounted-display and tested software filters to correct the problem; (5) In collaboration with Peter Wang and Mark Blasingame, established software and procedures for interfacing the VPL DataGlove and the Polhemus 6DOF position sensors to the SGI Indigo serial ports. The majority of the ISWE modeling effort was conducted on a PC-based VR Workstation, described below.

  2. Monitoring, field experiments, and geochemical modeling of Fe(II) oxidation kinetics in a stream dominated by net-alkaline coal-mine drainage, Pennsylvania, USA

    Cravotta,, Charles A.

    2015-01-01

    Watershed-scale monitoring, field aeration experiments, and geochemical equilibrium and kinetic modeling were conducted to evaluate interdependent changes in pH, dissolved CO2, O2, and Fe(II) concentrations that typically take place downstream of net-alkaline, circumneutral coal-mine drainage (CMD) outfalls and during aerobic treatment of such CMD. The kinetic modeling approach, using PHREEQC, accurately simulates observed variations in pH, Fe(II) oxidation, alkalinity consumption, and associated dissolved gas concentrations during transport downstream of the CMD outfalls (natural attenuation) and during 6-h batch aeration tests on the CMD using bubble diffusers (enhanced attenuation). The batch aeration experiments demonstrated that aeration promoted CO2 outgassing, thereby increasing pH and the rate of Fe(II) oxidation. The rate of Fe(II) oxidation was accurately estimated by the abiotic homogeneous oxidation rate law −d[Fe(II)]/dt = k1·[O2]·[H+]−2·[Fe(II)] that indicates an increase in pH by 1 unit at pH 5–8 and at constant dissolved O2 (DO) concentration results in a 100-fold increase in the rate of Fe(II) oxidation. Adjusting for sample temperature, a narrow range of values for the apparent homogeneous Fe(II) oxidation rate constant (k1′) of 0.5–1.7 times the reference value of k1 = 3 × 10−12 mol/L/min (for pH 5–8 and 20 °C), reported by Stumm and Morgan (1996), was indicated by the calibrated models for the 5-km stream reach below the CMD outfalls and the aerated CMD. The rates of CO2 outgassing and O2ingassing in the model were estimated with first-order asymptotic functions, whereby the driving force is the gradient of the dissolved gas concentration relative to equilibrium with the ambient atmosphere. Although the progressive increase in DO concentration to saturation could be accurately modeled as a kinetic function for the conditions evaluated, the simulation of DO as an instantaneous equilibrium process did not affect the

    With the aim of exchanging information on various subjects about radiation protection and designing a site where the members can send and receive information on courses, scientific activities, articles, technical opinions, commentaries and everything that promotes the communication, collaboration and integration, the 15th March 2002 the networking: 'radioproteccion' is created with 11 persons from 11 countries. The number of members had been increased. By the first month it had 117 members and by the end of the year 2002 it had already 179 members, 315 messages were send by then. By December 2007, there were 726 members from 28 countries mainly from Latin America: Argentina, Brazil, Bolivia, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela. There were also members from Austria, Canada, France, Israel, Italy, Portugal, Spain, Sweden, United Kingdom and United States. There have been distributed 2049 messages about Congress, courses and activities on national and international radiation protection and related issues which initially were in Latin American and the Caribbean. This has allowed diverse specialists that work in different themes to interchange experiences and information about subjects of common interest. This objective is the continuation of the spreading of activities that since 1991 and for 10 consecutive years had been made through the Bulletin 'Proteccion Radiologica', from which 65000 samples were published and distributed to specialists from 40 countries thanks to the support of the International Atomic Energy Agency (IAEA) and the Pan-American Health Organization (PAHO). This idea is complemented by the Web: www.radioproteccion.org. Interesting topics have been discussed in the network for example: Pregnancy and medical radiation, emergency response, occupational exposure, radiation protection responsibilities, lessons learned from accidental

    The Flight Dynamics Division (FDD) of the National Aeronautics and Space Administration (NASA) Goddard Space Flight Center (GFSC) provides extensive support and products for Space Shuttle missions, expendable launch vehicle launches, and routine on-orbit operations for a variety of spacecraft. A major challenge in providing support for these missions is defining and generating the products required for mission support and developing the method by which these products are exchanged between supporting agencies. As interagency and international cooperation has increased in the space community, the FDD customer base has grown and with it the number and variety of external interfaces and product definitions. Currently, the FDD has working interfaces with the NASA Space and Ground Networks, the Johnson Space Center, the White Sands Complex, the Jet propulsion Laboratory (including the Deep Space Network), the United States Air Force, the Centre National d'Etudes Spatiales, the German Spaceflight Operations Center, the European Space Agency, and the National Space Development Agency of Japan. With the increasing spectrum of possible data product definitions and delivery methods, the FDD is using its extensive interagency experience to improve its support of established customers and to provide leadership in adapting/developing new interfaces. This paper describes the evolution of the interfaces between the FDD and its customers, discusses many of the joint activities ith these customers, and summarizes key lessons learned that can be applied to current and future support.

    2005-06-01

    The main policy instruments currently used in the EU Member States to achieve the targets set for electricity produced from renewable energy sources are: (1) the quota obligation system; (2) the feed-in tariff system; and (3) the tendering system. The current study aims to review the experience gained with the quota obligation system. The report provides an overview of the regions where obligation systems have been implemented and contains a detailed evaluation of the performance of the obligation systems in the USA, the UK and in Sweden. The obligation systems in these countries have been evaluated based on the following criteria: Effectiveness; Market efficiency; Certainty for the renewable energy industry; Cost effectiveness; Stakeholder support for the obligation system; and Equity. The evaluation of international experiences with the obligation system gives rise to a mixed picture. Although an obligation in theory is effective and cost effective, it seems too early to conclude that the system delivers these promises in practice. On the one hand this is due to the limited period of implementation that makes it hard to distinguish between the direct effect of the system and some teething problems that will be solved in due time. On the other hand, the conclusion can be drawn that the obligation is a complex system, which will only function well if designed carefully. It does seem worthwhile, however, to continue monitoring the experiences with the obligation system abroad, because this will further reveal whether the system is indeed effective and cost effective in practice. In the longer term, e.g. beyond 2010, the introduction of an obligation system in the Netherlands could be considered. Finally, as the design of support schemes is being improved, it appears that the basic concepts of both the obligation system and the feed in system have been refined in such a way that the two systems are gradually converging. An important difference between the two systems

On the basis of the illuminated materials were obtained the following conclusions: Signifi cant interest in the Arctic show today, not only the fi ve countries (Russia, USA, Canada, Norway, Denmark, who own Arctic territories, but also polar state (Iceland, Sweden, Finland, the European Union and Asia. As a consequence of that, it is expected that in the XXI century the Arctic region will be the focus of attention as an official Arctic 45, and a number of states whose territory is quite removed from it; For Russia, given the current, acute political conditions (sanctions, confrontation with the West, Ukrainian crisis and war in the Middle East development of Arctic territories, some moved away, moved on tomorrow and the day after tomorrow on the agenda. This approach is fundamentally fl awed and fraught with a number of threats, because other countries do not decrease, but only increase their interest in this issue; Territorial opposition to all those involved in the topic of causing instability in the Arctic region, but does not represent a real threat for the emergence of large-scale conflict. Therefore, making the choice between the hard pressure of national interests and the interests of harmonization of the Arctic states, Russia must be based on international cooperationand mutual consideration of interests in the development of its Arctic strategy; Considering the cooperation of the countries of the Arctic Council and their cooperation in the framework of a global economic forum G8, there are prerequisites for the decision of the Arctic confl ict through negotiation and compromise. In this context it is very important to develop

  13. Regional Community and International Relations: the Volgograd Region Experience

    Directory of Open Access Journals (Sweden)

    Danakari Richard A.

    2016-06-01

    Full Text Available The article deals with the complex and controversial problems of the new regional communities’ formation and the impact of the interethnic relations sphere on them. The author notes that the processes of interaction between representatives of different cultures and civilizations, ethnic groups and religions have become increasingly controversial and tense in the context of continuous social dynamics. Similarly to the Russian society as a whole, regional communities are in a state of transitivity. They get transformed, they acquire new qualities such as multicasting and heterogeneity, multi-ethnicity and multi-confessionalism, fragmentarity and multiculturality. This fact increases the risks and uncertainties, problematizes future prospects. National non-governmental organizations are increasingly positioning themselves as civil society institutions at the present stage of social development at the regional level. They perform a difficult dual task: on the one hand, they ensure the preservation and development of history, native language, culture, ethnic traditions, and on the other hand, they work on the integration, on the common identity and the Russian nation formation. On the territory of the Volgograd region, largely due to the active cooperation of regional authorities and local authorities with national public associations, international and inter-confessional relations are stable. The basis of such activity is respect for history, native language, culture, tradition, religion, national dignity of all people in the region, regardless of their belonging to a certain ethnic group or religion. Over two decades of accumulated considerable experience of joint inter-ethnic dialogue and cooperation, provided tolerance and peace, harmony and mutual understanding between people of different ethnicities and religions in the country.

    International experiences with power sector restructuring and the resultant impacts on bulk power grid operations and planning may provide insight into policy questions for the evolving United States power grid as resource mixes are changing in response to fuel prices, an aging generation fleet and to meet climate goals. Australia, Germany, Japan and the UK were selected to represent a range in the level and attributes of electricity industry liberalization in order to draw comparisons across a variety of regions in the United States such as California, ERCOT, the Southwest Power Pool and the Southeast Reliability Region. The study draws conclusions through a literature review of the four case study countries with regards to the changing resource mix and the electricity industry sector structure and their impact on grid operations and planning. This paper derives lessons learned and synthesizes implications for the United States based on answers to the above questions and the challenges faced by the four selected countries. Each country was examined to determine the challenges to their bulk power sector based on their changing resource mix, market structure, policies driving the changing resource mix, and policies driving restructuring. Each countries’ approach to solving those changes was examined, as well as how each country’s market structure either exacerbated or mitigated the approaches to solving the challenges to their bulk power grid operations and planning. All countries’ policies encourage renewable energy generation. One significant finding included the low- to zero-marginal cost of intermittent renewables and its potential negative impact on long-term resource adequacy. No dominant solution has emerged although a capacity market was introduced in the UK and is being contemplated in Japan. Germany has proposed the Energy Market 2.0 to encourage flexible generation investment. The grid operator in Australia proposed several approaches to maintaining

    Ascites can lead to many symptoms, and often occurs in patients with an end-stage malignancy such as ovarian, pancreatic, colonic, or gastric cancer. Intermittent ascites drainage is applied in these patients as a palliative measure. As frequent drainage is necessary, a subcutaneously tunnelled permanent ascites catheter is a good alternative for intermittent drainage. The patient can open - and then re-close - the catheter when abdominal pressure increases. We inserted 35 subcutaneously permanent ascites catheters in the course of the past 3.5 years in the Leiden University Medical Centre. The success rate was 100% and the complication risk was 2.9%. A subcutaneously tunnelled ascites catheter is an effective and safe palliative treatment for patients with end-stage malignant disease and suffering from ascites.

    Objective Conventional, separate mediastinal and pleural tubes are often inefficient at draining thoracic effusions. Description We developed a Y-shaped chest tube with split ends that divide within the thoracic cavity, permitting separate intrathoracic placement and requiring a single exit port. In this study, thoracic drainage by the split drain vs. that of separate drains was tested. Methods After sternotomy, pericardiotomy, and left pleurotomy, pigs were fitted with separate chest drains (n=10) or a split tube prototype (n=9) with internal openings positioned in the mediastinum and in the costo-diaphragmatic recess. Separate series of experiments were conducted to test drainage of D5W or 0.58 M sucrose, an aqueous solution with viscosity approximating that of plasma. One litre of fluid was infused into the thorax, and suction was applied at −20 cm H2O for 30 min. Results When D5W was infused, the split drain left a residual volume of 53 ± 99 ml (mean value ± SD) vs. 148 ± 120 for the separate drain (P=0.007), representing a drainage efficiency (i.e. drained vol/[drained + residual vol]) of 95 ± 10% vs. 86 ± 12% for the separate drains (P = 0.011). In the second series, the split drain evacuated more 0.58 M sucrose in the first minute (967 ± 129 ml) than the separate drains (680 ± 192 ml, Pdrain evacuated a similar volume of sucrose vs. the conventional drain (1089 ± 72 vs. 1056 ± 78 ml; P = 0.5). Residual volume tended to be lower (25 ± 10 vs. 62 ± 72 ml; P = 0.128) and drainage efficiency tended to be higher (98 ± 1 vs. 95 ± 6%; P = 0.111) with the split drain vs. conventional separate drains. Conclusion The split chest tube drained the thoracic cavity at least as effectively as conventional separate tubes. This new device could potentially alleviate postoperative complications.

  20. Experimental and numerical analysis of the drainage of aluminium foams

    2005-01-01

    Drainage is one of the driving forces for the temporal instability of molten metal foams. For usual aqueous foams this phenomenon is well examined and understood on both the experimental and the theoretical side. The situation is different for metallic foams. Due to their opaque nature, the observation of drainage is only possible by either measuring the density distribution of solidified samples ex situ or by x-ray or neutron radioscopy. Up to now there exists just one theoretical study describing the drainage behaviour of metallic foams incorporating the drainage equation, the temperature dependence of the viscosity and thermal transport. This paper will present results on the drainage behaviour of aluminium foams grown by a powder-metallurgical production route. For this purpose an experiment which allows the observation of drainage in cylindrical metal foam columns has been developed. Experimental density profiles after different drainage times are measured ex situ and compared to numerical results of the standard drainage equation for aqueous foams. This first comparison between the density redistribution of metallic aluminium foams and numerical solutions shows that the standard drainage equation can be used to explain the drainage behaviour of metallic foams

    2010-01-01

    The infiltration of acid mine drainage (AMD) material into mine voids is one of the environmental impacts of underground coal mining. In this study, the mitigation of AMD in a mine void was simulated in laboratory conditions. Various mixtures of fly ash, solid residues, and Portland cement were added to packed columns over a 6-month period. The fly ash additions generated near-neutral to alkaline pH levels, which in turn induced precipitation, co-precipitation, and adsorption contaminant attenuation mechanisms. A modelling study demonstrated that the precipitation of ferrihydrite, Al-hydroxides, Al-oxyhydroxysulphates, gypsum, ettringite, manganite, and rhodochrosite lowered contaminant levels. Results of the study indicated that the pH regime and acidity level of the AMD strongly influenced both the leaching of the toxic trace elements as well as the attenuation of the AMD. 3 refs., 2 figs.

    2016-12-01

    Full Text Available Asian students make up the largest proportion of international students who study in the United States. Seeking a degree in higher education can be challenging for any student, but Asian students often encounter more obstacles to completion than many other international and domestic students. Culture, family and health concerns, and safety are some of the largest concerns that this study found among Asian students in the US. The study found that East-Asian international students had more issues than students from other parts of Asia and difficulty with the English language was of major importance to respondents. In addition, safety is an issue that Asian students were concerned with while studying in the US. The study was exploratory in nature and informs the field on future avenues of research.

    2014-01-01

    Full Text Available Education exchanges are a key element of public diplomacy for most countries that considered effective in that domain of foreign policy activities. Education exchanges are attributed an important role in the post-war peace settlement between Germany and France and in determining the outcome of the Cold war. Relevant aspects of public diplomacy remain key elements of foreign policy instruments of the US, Germany and many other countries. Russia has been increasingly active in public diplomacy in the past decade and the role of education exchanges has been increasing which is also demonstrated by a growing number of expert publications on the subject. However the strategy, the quality of organization and the use of modern technologies remain at a relatively low level which leads to an inefficient use of resources. Priority issues that can be a core of Russia's public diplomacy (and foreign policy in general. Moreover, systemic work would be required to evaluate efficiency of current and complete projects which would allow determine effectiveness of programs and appropriateness of resources used. Education exchanges need to be targeted at both bringing international students to Russia and assisting Russian students to study internationally and professors to teach abroad. Finally, international best practices show that there is a need to maintain connections with international exchanges alumni and assist them to maintain connections with each other including with the use of modern technologies.

    Objective: To evaluate the effect of PTBD in treating malignant biliary obstruction caused by hilar cholangiocarcinoma. Methods: We retrospectively analyzed the data of 103 patients(M:62,F:41)with malignant obstructive jaundice caused by hilar cholangiocarcinoma. After taking percutaneous transhepatic cholangiography, metallic stent or plastic external catheter or external-internal catheter for drainage was deployed and then followed up was undertaken with clinical and radiographic evaluation and laboratory. examination. Results: All patients went though PTBD successfully (100%). According to Bismuth classification, all 103 cases consisted of I type(N=30), II type (N=30), III type (N=26) and IV type (N=17). Thirty-nine cases were placed with 47 stents and 64 eases with drainage tubes. 4 cases installed two stems for bilateral drainage, 2 cases installed two stents because of long segmental strictures with stent in stent, 1 case was placed with three stents, and 3 cases installed stent and plastic catheter together. Sixty-four cases received plastic catheters in this series, 35 cases installed two or more catheters for bilateral drainage, 28 cases installed external and internal drainage catheters, 12 eases installed external drainage catheters, and 24 eases installed both of them. There were 17 patients involving incorporative infection before procedure, 13 cases cured after procedure, and 15 new patients got inflammation after procedure. 13 cases showed increase of amylase (from May, 2004), 8 eases had bloody bile drainage and 1 case with pyloric obstruction. Total serum bilirubin reduced from (386 ± 162) μmol/L to (161 ± 117) μmol/L, (P<0.01) short term curative effect was related with the type of hilar cholangiocarcinoma. The survival time was 186 days(median), and 1, 3, 6, 12 month survival rate were 89.9%, 75.3%, 59.6%, 16.9%, respectively. Conclusion: Percutaneous transhepatic bile drainage is a safe and effective palliative therapy of malignant

    2013-10-11

    Abstract Nursing education has increasingly turned to international learning experiences to educate students who are globally minded and aware of social injustices in local and global communities. To date, research with international learning experiences has focused on the benefits for the students participating, after they have completed the international experience. The purpose of this qualitative study was to explore how nursing students learn during the international experience. The sample consisted of eight nursing students who enrolled in an international learning experience, and data were collected in "real time" in Zambia. The students were observed during learning activities and were interviewed three times. Three major themes emerged from the thematic analysis: expectations shaped students' learning, engagement facilitated learning, and critical reflection enhanced learning. Implications are discussed, related to disrupting media representations of Africa that shape students' expectations, and educational strategies for transformative learning and global citizenship.

    Earthquake experience data was recognized as an efficient basis for verification of seismic adequacy of equipment installed on NPPs. This paper is meant to initiate a database setup in order to use the seismic experience to establish the generic seismic resistance of NPPs equipment applicable namely to the Middle and East European countries. Such earthquake experience database should be then compared to the already existing and well-known SQUG-GIP database. To set up such an operational earthquake database will require an important amount of effort. It must be understood that this goal can be achieved only based on a long term permanent activities and coordinated cooperation of various institutions. (author)

    2013-01-01

    Education in the ambulatory setting should be an integral part of undergraduate medical education. However, previous studies have shown education in this setting has been lacking in medical school. Ambulatory education occurs on some internal medicine clerkships. The extent of this education is unclear. The purpose of this survey was to assess the structure, curriculum, assessment methods, and barriers to implementation of ambulatory education on the internal medicine clerkship. An annual survey of institutional members of the Clerkship Directors in Internal Medicine (CDIM) was done in April 2010. The data were anonymous and descriptive statistics were used to summarize responses. Free text results were analyzed using qualitative techniques. The response rate was 75%. The majority of respondents had a required ambulatory component to the clerkship. Ambulatory experiences distinct from the inpatient internal medicine experience were common (46%). Integration with either the inpatient experiences or other departmental clerkships also occurred. The majority of ambulatory educational experiences were with generalists (74%) and/or subspecialists (45%). The most common assessment tool was the National Board of Medical Examiners (NBME) ambulatory shelf exam. Thematic analysis of the question about how practice based learning was taught elicited four major themes: Not taught; taught in the context of learning evidence based medicine; taught while learning chronic disease management with quality improvement; taught while learning about health care finance. Barriers to implementation included lack of faculty and financial resources. There have been significant increases in the amount of time dedicated to ambulatory internal medicine. The numbers of medical schools with ambulatory internal medicine education has increased. Integration of the ambulatory experiences with other clerkships such as family medicine occurs. Curriculum was varied but difficulties with dissemination

    The authors performed percutaneous drainage of lung abscesses in 12 patients. Indications for drainage were septicemia and persistence or worsening of radiographic findings. These lung abscesses were refractory to intravenous antibiotics and to bronchial toilet. Etiology of the abscesses included pneumonia (most frequently), trauma, postoperative development, infected necrotic neoplasm, and infected sequestration. Guidelines for drainage included passage of the catheter through contiguously abnormal lung and pleura, inability of the patient to cough, and/or bronchial obstruction precluding bronchial drainage. Cure was achieved in 11 of 12 patients. Catheters were removed on an average of 16 days after insertion. Antibiotics were administered an average of 18 days before drainage. No major complications occurred

  3. Acid mine drainage

    Science.gov (United States)

    Bigham, Jerry M.; Cravotta, Charles A.

    2016-01-01

    Acid mine drainage (AMD) consists of metal-laden solutions produced by the oxidative dissolution of iron sulfide minerals exposed to air, moisture, and acidophilic microbes during the mining of coal and metal deposits. The pH of AMD is usually in the range of 2–6, but mine-impacted waters at circumneutral pH (5–8) are also common. Mine drainage usually contains elevated concentrations of sulfate, iron, aluminum, and other potentially toxic metals leached from rock that hydrolyze and coprecipitate to form rust-colored encrustations or sediments. When AMD is discharged into surface waters or groundwaters, degradation of water quality, injury to aquatic life, and corrosion or encrustation of engineered structures can occur for substantial distances. Prevention and remediation strategies should consider the biogeochemical complexity of the system, the longevity of AMD pollution, the predictive power of geochemical modeling, and the full range of available field technologies for problem mitigation.

    Full Text Available Abstract Background Few studies have addressed the challenges that international medical students face and there is a dearth of information on the behavioural strategies these students adopt to successfully progress through their academic program in the face of substantial difficulties of language barrier, curriculum overload, financial constraints and assessment tasks that require high proficiency in communication skills. Methods This study was designed primarily with the aim of enhancing understanding of the coping strategies, skill perceptions and knowledge of assessment expectations of international students as they progress through the third and fourth years of their medical degree at the School of Medicine, University of Tasmania, Australia. Results Survey, focus group discussion and individual interviews revealed that language barriers, communication skills, cultural differences, financial burdens, heavy workloads and discriminatory bottlenecks were key factors that hindered their adaptation to the Australian culture. Quantitative analyses of their examination results showed that there were highly significant (p Conclusions Despite the challenges, these students have adopted commendable coping strategies and progressed through the course largely due to their high sense of responsibility towards their family, their focus on the goal of graduating as medical doctors and their support networks. It was concluded that faculty needs to provide both academic and moral support to their international medical students at three major intervention points, namely point of entry, mid way through the course and at the end of the course to enhance their coping skills and academic progression. Finally, appropriate recommendations were made.

    Full Text Available The purpose of this paper is to examine the requirements and successes of the New International Financial Architecture (NIFA on transparency and corporate governance from a global perspective with a special focus on Africa. In recent years, transparency, accountability and governance have become key topics with many countries around the world having adopted International Financial Reporting Standards (IFRS and corporate governance codes. The outcomes of these initiatives have been unconvincing. Desktop research was used to gather literature and data on compliance with corporate governance codes and International Financial Reporting Standards (IFRS and other NIFA requirements. This study established that in spite of many regional and global initiatives by the World Bank and relevant regulators, compliance with IFRS and governance in parts of Africa has yet to reach its best level and guidelines are not fully followed leading to opportunities for improvement and policy adjustments. This research has implications and uses for both global and local institutions and regulators concerned with economic stability and growth including the World Bank, central banks, capital markets and boards of companies and the government in general. The findings contribute to governance debates by providing additional perspectives from Africa on compliance with accounting standards and codes in a region where research and corporate governance and reporting issues are still confusing.

    This study investigated the effects of experiences with weight stigma and weight bias internalization on exercise. An online sample of 177 women with overweight and obesity (M(age) = 35.48 years, M(BMI) = 32.81) completed questionnaires assessing exercise behavior, self-efficacy, and motivation; experiences of weight stigmatization; weight bias internalization; and weight-stigmatizing attitudes toward others. Weight stigma experiences positively correlated with exercise behavior, but weight bias internalization was negatively associated with all exercise variables. Weight bias internalization was a partial mediator between weight stigma experiences and exercise behavior. The distinct effects of experiencing versus internalizing weight bias carry implications for clinical practice and public health. © The Author(s) 2014.

    The International Science Olympiad is an international intellectual olympic in which students, aging under 20 and who have not entered university, compete using their creative problem solving skills in the field of science. Many nations participate in the Olympiad with great interest, for this competition is a global youth science contest which is also used to measure national basic science levels. However in Korea, benefits for Olympiad participants were reduced because issues were risen that the Olympiad could intensify private education. This resulted in a continuous decrease in the number of applicants, bringing national competitiveness deterioration to concern. Therefore in this study, we identified the problems by analyzing the actual conditions of Olympiad participants' private education, and sought support plans to activate Olympiad participation. For this use, we conducted a survey of 367 summer school and winter school acceptees in 9 branches. 68.9% of the students were preparing for the Olympiad by private education, and the highest percentage answered that their private education expenses were an average of 3~5 million won. Olympiad preparation took up 30~50% of all private education, showing that private education greatly influences the preparing processes for the Olympiad. Meanwhile the participants perceived that in order to reduce Olympiad-related private education, the following should be implemented priority: supply of free high-quality on-line education materials, and easy access to Olympiad related information. It was also suggested that the most effective and needed education methods were school olympiad preparation classes, on-line education expansion, and special lectures and mentoring from olympiad-experienced senior representatives. Additionally, as methods to activate Olympiad participation, it was thought that award records should be allowed to be used in college applications by enabling award records into student records and special

    Endoscopic drainage has become the standard of care for the treatment of mucoceles. In many patients this can be performed in the office. This study reviews our experience with in-office endoscopic mucocele drainage. Retrospective chart review. A retrospective review of one surgeon's experience with in-office endoscopic drainage of sinus mucoceles between 2006 and 2014 was performed. Charts were reviewed for patient demographics, previous surgery, mucocele location, bone erosion, and outcomes. Thirty-two patients underwent 36 in-office drainage procedures. All procedures were performed under topical/local anesthesia. The mean age was 55 years (range, 17-92 years). The mean follow-up time was 444 days. Fifty-five percent had previous sinus surgery. The primary sinus involved was the frontal (12), anterior (11), posterior ethmoid (six), maxillary (four), and sphenoid (two). Bone erosion was noted to be present on computed tomography in 18 mucoceles (51%) (16 orbital, seven skull-base). All mucoceles were successfully accessed in the office with the exception of one, which was aborted due to neo-osteogenesis. Five patients (14% of mucoceles) required additional surgery, two for mucocele recurrence and three for septated mucoceles not completely drained in the office. No treatment complications occurred. All but one patient preferred in-office to operating-room drainage. In-office drainage of sinus mucoceles is well tolerated by patients, with high success and low complication rates, even in large mucoceles with bone erosion. The presence of septations and neo-osteogenesis reduce the likelihood of complete drainage and are relative contraindications. Orbital and skull base erosion are not contraindications. 4. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

  18. Financing of internal displacement: excerpts from the Sri Lankan experience.

    2010-04-01

    This paper investigates how internally displaced persons (IDPs) in Batticaloa, Sri Lanka, financed their first year of displacement. We conducted extensive fieldwork in August 2007 in numerous welfare centres in Batticaloa that have received persons displaced from the Mutur divisional secretariat (DS) in the Trincomalee district. The sample was selected from the village of Sampur in Mutur DS. The displaced from Sampur are of Tamil origin and our findings reveal certain coping strategies that may be particular to this community, including the selling or mortgaging of gold jewellery to address the effects of displacement. We found that the IDPs in this region rely heavily on jewellery and other forms of savings to ensure their survival. There is also strong evidence to support the critically important coping role played by livelihoods. These coping strategies have enabled the IDP households in the present sample to live marginally above the poverty line.

    Percutaneous transhepatic biliary drainage is a safe, effective and palliative means of treatment in biliary obstruction, especially in cases with malignant obstruction which are inoperable. 175 cases of transhepatic biliary drainage were performed on 119 patients with biliary obstruction from January 1985 to June 1989 at Kyung-pook National University Hospital. The causes of obstructive jaundice were 110 malignant diseases and 9 benign diseases. The most common indication for drainage was palliative intervention of obstruction secondary to malignant tumor in 89 cases. 86 cases of external drainage were performed including 3 cases of left duct approach, 29 cases of external-internal drainage and 60 cases of endoprosthesis. In external and external-internal drainages, immediate major complications (11.9%) occurred, including not restricted to, but sepsis, bile peritonitis and hemobilia. Delayed major complications (42.9%) were mainly catheter related. The delayed major complication of endoprosthesis resulted from obstruction of the internal stent. The mean time period to reobstruction of the internal stent was about 12 weeks. To improve management status, regular follow-up is required, as is education of both patients and their families as to when immediate clinical attention is mandated. Close communication amongst the varying medical specialities involved will be necessary to provide optional treatment for each patient.

    The generation and release of acidic drainage containing high concentrations of dissolved metals from decommissioned mine wastes is an environmental problem of international scale. A potential solution to many acid drainage problems is the installation of permeable reactive walls into aquifers affected by drainage water derived from mine waste materials. A permeable reactive wall installed into an aquifer impacted by low-quality mine drainage waters was installed in August 1995 at the Nickel Rim mine site near Sudbury, Ontario. The reactive mixture, containing organic matter, was designed to promote bacterially mediated sulfate reduction and subsequent metal sulfide precipitation. The reactive wall is installed to an average depth of 12 feet (3.6 m) and is 49 feet (15 m) long perpendicular to ground water flow. The wall thickness (flow path length) is 13 feet (4 m). Initial results, collected nine months after installation, indicate that sulfate reduction and metal sulfide precipitation is occurring. The reactive wall has effectively removed the capacity of the ground water to generate acidity on discharge to the surface. Calculations based on comparison to previously run laboratory column experiments indicate that the reactive wall has potential to remain effective for at least 15 years

  7. Lessons learned from international siting experiences of LLW Disposal facilities

    McCabe, G.H.

    1990-01-01

    This paper reports that the United States can gain insight into successfully siting low-level radioactive waste (LLW) disposal facilities by studying the process in other nations. Siting experiences in France and Sweden are compared to experiences in the United States. Three factors appear to making siting of LLW disposal facilities easier in France and Sweden than in the United States. First, the level of public trust in the government and the entities responsible for siting, developing, and operating a LLW disposal facility is much greater in France and Sweden than in the United States. Second, France and Sweden are much more dependent on nuclear power than is the United States. Third, French and Swedish citizens do not have the same access to the siting process (i.e., legal means to intervene) as do U.S. citizens. To compensate for these three factors, public officials responsible for siting a facility may need to better listen to the concerns of public interest groups and citizen advisory committees and amend their siting process accordingly and better share power and control with the public. If these two techniques are implemented earnestly by the states, siting efforts may be increasingly more successful in the United States

    Man power development is an essential key to success in implementing nuclear projects, especially when maximum local participation is an important issue in every sector of nuclear industry. Bearing this in mind, the Korean Atomic Energy Research Institute (KAERI) founded the Nuclear Training Center (NTC). The Center began to train technical personnel in the fields of radioisotope utilization and radiation protection in 1960s. During the first stage of nuclear power project in ROK in 1970s, the main effort was exerted to the training of those in nuclear power and nuclear engineering sectors. During the stage of increased technical self-reliance in 1980s, its training role was extended to the implementation of more specific training courses on nuclear power and safety fields. As of the end of 1995, about 23,000 people received the training courses. In an attempt to upgrade the nuclear technology, the advanced training courses at the NTC by invited foreign experts and by IAEA technical cooperation program have been implemented. Also the training under IAEA Regional Cooperative Agreement in Asia Pacific Region has been offered. The change of the NTC to the International Training Center is recommended. (K.I.)

    A compilation of the available experimental internal conversion coefficients (ICCs), α T , α K , α L , and ratios K/L and K/LM of high multipole (L > 2) transitions for a number of elements in the range 21 ≤ Z ≤ 94 is presented. Our listing of experimental data includes 194 data sets on 110 E3 transitions, 10 data sets on 6 E4 transitions, 11 data sets on 7 E5 transitions, 38 data sets on 21 M3 transitions, and 132 data sets on 68 M4 transitions. Data with less than 10% experimental uncertainty have been selected for comparison with the theoretical values of Hager and Seltzer [R.S. Hager, E.C. Seltzer, Nucl. Data Tables A 4 (1968) 1], Rosel et al. [F. Roesel, H.M. Fries, K. Alder, H.C. Pauli, At. Data Nucl. Data Tables 21 (1978) 91], and BRICC. The relative percentage deviations (%Δ) have been calculated for each of the above theories and the averages (%Δ-bar) are estimated. The Band et al. [I.M. Band, M.B. Trzhaskovskaya, C.W. Nestor Jr., P.O. Tikkanen, S. Raman, At. Data Nucl. Data Tables 81 (2002) 1] tables, using the BRICC interpolation code, are seen to give theoretical ICCs closest to experimental values

  10. The Conceptualization of Energy Security: the International Experience

    2017-08-01

    Full Text Available The article reviews and analyzes existing interpretations of the term of «energy security», which are used by international organizations, individual countries, and foreign scientists. As result of a generalization of the numerous existing conceptual-methodical and substantive approaches to the definition of energy security, its main components and possible ways of its ensuring, it has been found that the concept of energy security includes many multifactor components that are interconnected by numerous functional linkages, including economic, political, social, and ecological aspects. The issues related to geology, geography, and time factor have impact on interpretation of energy security. But in general, energy security can be seen in a one-aspect dimension that is largely based on the security of energy supplies (availability of energy resources and in a multi-aspect dimension which, in addition to the security of energy supplies, also takes into consideration a number of other important interrelated aspects of energy security, particularly in the areas of accessibility of energy resources, energy efficiency, and environmental safety.

    Objectives: This article reports and analyses conversation with eight international educators in Europe, Canada, the United States, New Zealand and Australia. All are managing the impact of technology in different ways (reactive and pro-active, at different levels (pre-primary through to senior citizen, in different roles (teachers, administrators and senior managers and in different contexts (schools and universities. Method: Open-ended conversations with educators and educational administrators in developed countries were recorded, transcribed and analysed. The qualitative analysis of the content was done in the style of ‘open coding’ and ‘selective coding’ using a qualitative content analysis tool. Results: Whilst technology is still seen to drive much thinking, it is found that that success is not derived from the technology, but from a full and proper understanding of the needs and aspirations of those who are directly involved in educational processes, and by means of a managerial focus that properly recognises the context within which an institution exists. Conclusion: Whilst this result might be expected, the detailed analysis of the findings further reveals the need to manage investments in educational technologies at different levels and in different ways.

    Full Text Available ABSTRACT Objective: to identify predictors of chest drainage complications in trauma patients attended at a University Hospital. Methods: we conducted a retrospective study of 68 patients submitted to thoracic drainage after trauma, in a one-year period. We analyzed gender, age, trauma mechanism, trauma indices, thoracic and associated lesions, environment in which the procedure was performed, drainage time, experience of the performer, complications and evolution. Results: the mean age of the patients was 35 years and the male gender was the most prevalent (89%. Blunt trauma was the most frequent, with 67% of cases, and of these, 50% were due to traffic accidents. The mean TRISS (Trauma and Injury Severity Score was 98, with a mortality rate of 1.4%. The most frequent thoracic and associated lesions were, respectively, rib fractures (51% and abdominal trauma (32%. The mean drainage time was 6.93 days, being higher in patients under mechanical ventilation (p=0.0163. The complication rate was 26.5%, mainly poor drain positioning (11.77%. Hospital drainage was performed in 89% of cases by doctors in the first year of specialization. Thoracic drainage performed in prehospital care presented nine times more chances of complications (p=0.0015. Conclusion: the predictors of post-trauma complications for chest drainage were a procedure performed in an adverse site and mechanical ventilation. The high rate of complications demonstrates the importance of protocols of care with the thoracic drainage.

    Radiation detectors monitored trains at two international borders to evaluate the performance of NaI(Tl) and plastic (polyvinyltoluene: PVT) gamma-ray detectors to characterize rail cargo. The detectors included a prototype NaI(Tl) radiation-portal-monitor panel having four large detectors (10-cm × 10-cm × 41-cm) and a PVT panel with a 41 cm × 173 cm × 3.8-cm detector. Spectral data from the NaI(Tl) and PVT detectors were recorded. Of particular emphasis was the identification of naturally occurring radioactive material (NORM) and the resultant frequency of nuisance alarms. For rail monitoring, the difficulty in stopping trains to perform secondary inspection on alarming cars creates a need for reliable identification of NORM during initial screening. Approximately 30 trains were monitored, and the commodities in individual railcars were ascertained from manifest information. At one test site, the trains carried inter-modal containers that had been unloaded from ships, and at the other site, the trains contained bulk cargo in tanker cars and hopper cars or individual items in boxcars or flatbeds. NORM encountered included potash, liquefied petroleum gas, fireworks, televisions, and clay-based products (e.g., pottery). Analysis of the spectral data included the use of the template-fitting portion of the program GADRAS developed at Sandia National Laboratories. For most of the NORM, the NaI(Tl) data produced a correct identification of the radionuclides present in the railcars. The same analysis was also used for PVT data in which the spectral information (no peaks but only gradual spectral changes including Compton edges) was limited. However, the PVT analysis provided correct identification of 40K and 226Ra in many cases.

  18. Opposition to nuclear power: a review of international experience

    Energy Technology Data Exchange (ETDEWEB)

    Surrey, J; Huggett, C

    1976-12-01

    This paper examines the rise of opposition to nuclear power in the USA, the Federal Republic of Germany, France, Sweden, and Japan. It explores the course that opposition has taken, the issues on which it has focused, the factors that have influenced it, and the problems it poses for public decision making. Opinions differ about the causes of nuclear opposition. Indeed, it is probable that a variety of factors have contributed, including cultural and political values regarding continued economic and energy growth and fears of deliberate large-scale violence with the spread of radioactive materials, the protest movements against nuclear weapons testing, the upsurge in environmental concern in the 1960s, the movement towards greater social responsibility in science, and a growing distrust of ''the Establishment''--particularly in the USA because of Watergate. The upsurge in concern was reflected in greater attention to environmental matters in the mass media, schools, universities, and the international agencies. It is important to recognize that this concern cuts across conventional left-right divisions of politics. Radicals, communists, and conservatives can be found among both the proponents and the critics. These difficulties facing the policy maker are accentuated by the amorphous nature both of the opposition and the issues which have received attention and by the evidence of many opinion surveys: that more people are in favor of nuclear power than oppose it, but the majority are uncertain and do not understand the issues. For purposes of analysis it is useful to distinguish between three types of opposition--nuclear-specific, site-specific, and that related to planning and consent procedures. (MCW)

    The nature of hospital activity is changing in many countries, with some experiencing a broad trend towards the creation of hospital groups or chains and multi-hospital networks. This study seeks to contribute to the understanding of experiences in other countries about the extent to which different hospital "models" may provide lessons for hospital provision in England by means of a review of four countries: France, Germany, Ireland and the United States, with England included for comparison. We find that there has been a trend towards privatisation and the formation of hospital groups in France, Germany, and the United States although it is important to understand the underlying market structure in these countries explaining the drivers for hospital consolidation. Thus, and in contrast to the NHS, in France, Germany, and the United States, private hospitals contribute to the delivery of publicly funded healthcare services. There is limited evidence suggesting that different forms of hospital cooperation, such as hospital groups, networks or systems, may have different impacts on hospital performance. Available evidence suggests that hospital consolidation may lead to quality improvements as increased size allows for more costly investments and the spreading of investment risk. There is also evidence that a higher volume of certain services such as surgical procedures is associated with better quality of care. However, the association between size and efficiency is not clear-cut and there is a need to balance "quality risk" associated with low volumes and "access risk" associated with the closure of services at the local level.

  12. Status of the international Muon ionization cooling experiment

    International Nuclear Information System (INIS)

    Palladino, V.; Bonesini, M.

    2009-01-01

    Muon ionization cooling provides the only practical solution to prepare high brilliance beams necessary for a neutrino factory or muon colliders. The muon ionization cooling experiment (MICE) is under development at the Rutherford Appleton Laboratory (UK). It comprises a dedicated beam line to generate a range of input emittance and momentum, with time-of-flight and Cherenkov detectors to ensure a pure muon beam. A first measurement of emittance is performed in the upstream magnetic spectrometer with a scintillating fiber tracker. A cooling cell will then follow, alternating energy loss in liquid hydrogen and RF acceleration. A second spectrometer identical to the first one and a particle identification system provide a measurement of the outgoing emittance. By July 2009 it is expected that the beam and first set of detectors will have been commissioned and a first measurement of input beam emittance may be reported. Along with the steps in the measurement of emittance reduction (cooling) that will follow later and in 2010. (authors)

  13. Entombment Using Cementitious Materials: Design Considerations and International Experience

    Energy Technology Data Exchange (ETDEWEB)

    Seitz, Roger Ray

    2002-08-01

    Cementitious materials have physical and chemical properties that are well suited for the requirements of radioactive waste management. Namely, the materials have low permeability and durability that is consistent with the time frame required for short-lived radionuclides to decay. Furthermore, cementitious materials can provide a long-term chemical environment that substantially reduces the mobility of some long-lived radionuclides of concern for decommissioning (e.g., C-14, Ni-63, Ni-59). Because of these properties, cementitious materials are common in low-level radioactive waste disposal facilities throughout the world and are an attractive option for entombment of nuclear facilities. This paper describes design considerations for cementitious barriers in the context of performance over time frames of a few hundreds of years (directed toward short-lived radionuclides) and time frames of thousands of years (directed towards longer-lived radionuclides). The emphasis is on providing an overview of concepts for entombment that take advantage of the properties of cementitious materials and experience from the design of low-level radioactive waste disposal facilities. A few examples of the previous use of cementitious materials for entombment of decommissioned nuclear facilities and proposals for the use in future decommissioning of nuclear reactors in a few countries are also included to provide global perspective.

    Nuclear power occupies nowadays the third place among the different sources of energy in the world (17%), after coal (40%) and hydropower (18%). In the more developed countries of OECD (Organization for Economic Cooperation and Development), nuclear power already represents the second most utilized source of energy (coal; 40%, nuclear: 24%, hydro: 17%). It has been frequently stated that inadequate public information constitutes one of the main hindrances for broad use worldwide of nuclear power. However, in those countries where nuclear power has been more successful their well informed populations are generally in favor of its utilization. In countries like France, Japan, Republic of Korea and the U.S., big users of nuclear power, public opinion has been either in favor or has evolved favorably to the nuclear option. The experience in this field varies from country to country, depending mainly on their cultural and socio-political traditions. This report summarizes the situation in various countries as background information for possible adaptation to the conditions in Brazil. (author)

    The SCaN Testbed is an advanced integrated communications system and laboratory facility installed on the International Space Station (ISS) in 2012. The testbed incorporates a set of new generation of Software Defined Radio (SDR) technologies intended to allow researchers to develop, test, and demonstrate new communications, networking, and navigation capabilities in the actual environment of space. Qascom, in cooperation with ESA and NASA, is designing a Software Defined Radio GalileoGPS Receiver capable to provide accurate positioning and timing to be installed on the ISS SCaN Testbed. The GalileoGPS waveform will be operated in the JPL SDR that is constituted by several hardware components that can be used for experimentations in L-Band and S-Band. The JPL SDR includes an L-Band Dorne Margolin antenna mounted onto a choke ring. The antenna is connected to a radio front end capable to provide one bit samples for the three GNSS frequencies (L1, L2 and L5) at 38 MHz, exploiting the subharmonic sampling. The baseband processing is then performed by an ATMEL AT697 processor (100 MIPS) and two Virtex 2 FPGAs. The JPL SDR supports the STRS (Space Telecommunications Radio System) that provides common waveform software interfaces, methods of instantiation, operation, and testing among different compliant hardware and software products. The standard foresees the development of applications that are modular, portable, reconfigurable, and reusable. The developed waveform uses the STRS infrastructure-provided application program interfaces (APIs) and services to load, verify, execute, change parameters, terminate, or unload an application. The project is divided in three main phases. 1)Design and Development of the GalileoGPS waveform for the SCaN Testbed starting from Qascom existing GNSS SDR receiver. The baseline design is limited to the implementation of the single frequency Galileo and GPS L1E1 receiver even if as part of the activity it will be to assess the

Most SuDS, such as infiltration trenches, swales, green roofs, ponds, and wetlands, address water quality and quantity challenges, and enhance the local biodiversity while also being acceptable aesthetically to the public. Barriers to the implementation of SuDS include adoption problems, flood and diffuse pollution control challenges, negative public perception, and a lack of decision support tools addressing, particularly, the retrofitting of these systems while enhancing ecosystem services.

    Full Text Available Romanian students′ appreciation towards international experience has been increasing as the number of students involved in international programs has been rising year by year. Also, students′ expectations upon graduation are more related to finding a good job, usually in multinationals. Studies conducted in Romania (Frunzaru et al., 2013 and (Nicolescu and Păun, 2009 showed that students give great attention to the skills they acquire after completing various programs, often their choices being focused on several successful areas and international programs. The joint projects of several universities and governmental authorities in Romania have aimed to develop the international dimension of education (IEMU, 2015. The results of implementing those projects could be revealed by students’ perception of international competences gained by curricula or international exchange programs. The purpose of this paper is to analyze the dynamics of Romanian and European graduates’ satisfaction with international experience and extracurricular resources accessed during university courses. Also, the article will analyze the dynamics of graduates′ career priorities in accordance with the skills provided upon graduation. The data are selected from Trendence Graduate Barometer - Romanian Edition and the analysis establishes relevant conclusions regarding the young Romanian graduates′ need to develop, in comparison with European graduates from 5-year statistic data (2012-2016. The conclusions include a comparison of international exchange programs and career priorities expectations among Romanian and other European graduates. Also, the paper will draw new research directions regarding students′ need for specialization especially in gaining international competences.

    To determine if stable patients with a hemopericardium detected after penetrating chest trauma can be safely managed with pericardial drainage alone. The current international practice is to perform a sternotomy and cardiac repair if a hemopericardium is detected after penetrating chest trauma. The experience in Cape Town, South Africa, on performing a mandatory sternotomy in hemodynamically stable patients was that a sternotomy was unnecessary and the cardiac injury, if present, had sealed. A single-center parallel-group randomized controlled study was completed. All hemodynamically stable patients with a hemopericardium confirmed at subxiphoid pericardial window (SPW), and no active bleeding, were randomized. The primary outcome measure was survival to discharge from hospital. Secondary outcomes were complications and postoperative hospital stay. Fifty-five patients were randomized to sternotomy and 56 to pericardial drainage and wash-out only. Fifty-one of the 55 patients (93%) randomized to sternotomy had either no cardiac injury or a tangential injury. There were only 4 patients with penetrating wounds to the endocardium and all had sealed. There was 1 death postoperatively among the 111 patients (0.9%) and this was in the sternotomy group. The mean intensive care unit (ICU) stay for a sternotomy was 2.04 days (range, 0-25 days) compared with 0.25 days (range, 0-2) for the drainage (P drainage group (95% CI: 0.8-2.7). Total hospital stay was significantly shorter in the SPW group (P drainage is effective and safe in the stable patient with a hemopericardium after penetrating chest trauma, with no increase in mortality and a shorter ICU and hospital stay.

    Full Text Available Fungal endophthalmitis is rare but may complicate glaucoma drainage device surgery. Management is challenging as the symptoms and signs may be subtle at initial presentation and the visual prognosis is usually poor due to its resistant nature to treatment. At present there is lesser experience with intravitreal injection of voriconazole as compared to Amphotericin B. We present a case of successfully treated Aspergillus endophthalmitis following Baerveldt glaucoma drainage device implantation with intravitreal and topical voriconazole.

    In order to conduct the production experiments with polarized deuterium target and (un)polarized proton beam at ANKE/COSY, a commissioning experiment of the polarized internal target with deuterium is imperative. The commissioning experiment includes the measurements of both the vector (Q{sub y}) and tensor (Q{sub yy}) polarization of the deuterium gas target through the nuclear reactions with large and well known analyzing powers, which can be detected in ANKE. The dependence of the polarizations along the storage cell is also determined. The poster presents the physics case for the experiments with deuterium polarized internal target and the apparatus needed for the commissioning experiment, as well as the procedure of extraction for spin observables.

    International or foreign students are those who enrol in universities outside their country of citizenship. They face many challenges acculturating to and learning in a new country and education system, particularly if they study in an additional language. This qualitative inquiry aimed to explore the learning and acculturating experiences of international nursing students to identify opportunities for teaching innovation to optimise the experiences and learning of international nursing students. Undergraduate and postgraduate international nursing students were recruited from one campus of an Australian university to take part in semi-structured interviews. A purposive and theoretically saturated sample of 17 students was obtained. Interviews were audio-recorded and field notes and interview data were thematically analysed. Expressing myself and Finding my place were the two major themes identified from the international student data. International nursing students identified that it took them longer to study in comparison with domestic students and that stress negatively influenced communication, particularly in the clinical setting. Additionally international nursing students identified the need to find supportive opportunities to speak English to develop proficiency. Clinical placement presented the opportunity to speak English and raised the risk of being identified as lacking language proficiency or being clinically unsafe. Initially, international nursing students felt isolated and it was some time before they found their feet. In this time, they experienced otherness and discrimination. International nursing students need a safe place to learn so they can adjust and thrive in the university learning community. Faculty and clinical educators must be culturally competent; they need to understand international nursing students' needs and be willing and able to advocate for and create an equitable environment that is appropriate for international nursing

This handbook presents simplified homogeneous model experiments with relevant experimental data, as amended. The Nuclear Energy Agency of the Organization for Economic Cooperation and Development coordinates the activities of two international projects on the collection, evaluation and documentation of experimental data - the International Project on the assessment of critical experiments (1994) and the International Project on the assessment of reactor experiments (since 2005). The result of the activities of these projects are replenished every year, an international directory of critical (ICSBEP Handbook) and reactor (IRPhEP Handbook) experiments. The handbooks present detailed models of experiments with minimal amendments. Such models are of particular interest in terms of the settlements modern programs. The directories contain a large number of experiments which are suitable for the study of physics of fast reactors. Many of these experiments were performed at specialized critical stands, such as BFS (Russia), ZPR and ZPPR (USA), the ZEBRA (UK) and the experimental reactor JOYO (Japan), FFTF (USA). Other experiments, such as compact metal assembly, is also of interest in terms of the physics of fast reactors, they have been carried out on the universal critical stands in Russian institutes (VNIITF and VNIIEF) and the US (LANL, LLNL, and others.).

    Similar techniques for draining abdominal abscesses are now being applied to abscesses within the chest. This report describes the authors' experience in percutaneous drainage of seven chest abscesses in six children aged 3-13 years (mean, 7.3 years). Four pleural/extrapleural loculations were drained in three patients. Abscess location included right apex (one), right minor fissure (one), and left supradiaphragmatic (two). Collections resulted from esophageal perforation (two) or esophageal anastomotic leak (two). Three lung abscesses were drained in three patients. Abscess location included right lower, left lower, and right middle lobes. All lay adjacent to a pleural surface and were localized by CT or US before drainage. There were no complications. Complete resolution occurred in all six patients without the need for surgical intervention

    The purpose of this study was to explore the experiences of internationally educated nurses in management positions in United States health care organisations to understand the obstacles and support these individuals' experience when pursuing and working in managerial roles. Although internationally educated nurses are an integral part of the US health care industry, few work in managerial roles. Little is known about the experiences of internationally educated nurses who do obtain management positions. In this qualitative, phenomenological study, seven internationally educated nurses who were managers in Chicago, Illinois, responded to open-ended interview questions. Supervisors contributed to the participants' acceptance of management positions. The participants experienced challenges such as cultural differences, language, and communication. Despite these challenges, the participants had positive working relationships with staff and supervisors. Further, the participants had opportunities for education and professional growth. Internationally educated nurses benefit from participating in organisational committees. They face challenges related to work responsibilities, cultural differences and communication but can succeed in management roles through developing strategies to overcome the challenges and through receiving support from staff, colleagues and supervisors. More internationally educated nurses may obtain managerial positions if supervisors provide encouragement and support. © 2018 John Wiley & Sons Ltd.

    Medical treatment using antibiotics and postural drainage has been widely adopted as a treatment method of pulmonary abscess, accompanied by surgical methods in cases intractable to drug therapy. However long-term therapy may be required, and the tolerance of organisms to antibiotics or other complications are apt to be encountered, during medical treatment. To shorten the convalescent period or to decrease the risk of invasive procedures, rather simple and relatively easy interventional techniques such as transbronchial or percutaneous catheter drainage have been successfully tried. We have performed 12 cases of percutaneous drainages of lung abscesses under fluoroscope guidance. This report is on the results of this procedure.

    Helena M. Ramos

    2017-11-01

    Full Text Available Sustainability is crucial to the urban zones, especially related to the water management, which is vulnerable to flood occurrence. This research applies the procedure contemplated by the Soil Conservation Service (SCS to determine the generated volumes when the impervious areas can exceed the drainage capacity of existing pluvial water networks. Several computational simulations were developed for the current scenario of an existing basin in Lisbon. Using CivilStorm software from Bentley Systems (Bentley EMEA, Bentley Systems International Limited, Dublin, Ireland, it enabled the evaluation of the volumes of flood peaks and the hydraulic behavior of a small hydrographic basin in the continuation of an urbanization process, considering the modification of its superficial impervious parts and the growth of the urbanized area. Several measures are suggested to solve the limited capacity of the existing drainage system. This study analyzes the efficiency of the application of constructive measures, pondering the viability of their effectiveness, individually and combined. The option that best minimizes the effects of the urbanization is the combination of different structural measures, in particular retention ponds, storage blocks, ditches and specific drainage interventions in some parts of the network.

    We aimed to determine whether infants undergoing cardiac surgery would more efficiently attain negative fluid balance postoperatively with passive peritoneal drainage as compared to traditional pleural drainage. A prospective, randomized study including children undergoing repair of tetralogy of Fallot (TOF) or atrioventricular septal defect (AVSD) was completed between September 2011 and June 2013. Patients were randomized to intraoperative placement of peritoneal catheter or right pleural tube in addition to the requisite mediastinal tube. The primary outcome measure was fluid balance at 48 hours postoperatively. Variables were compared using t tests or Fisher exact tests as appropriate. A total of 24 patients were enrolled (14 TOF and 10 AVSD), with 12 patients in each study group. Mean fluid balance at 48 hours was not significantly different between study groups, -41 ± 53 mL/kg in patients with periteonal drainage and -9 ± 40 mL/kg in patients with pleural drainage (P = .10). At 72 hours however, postoperative fluid balance was significantly more negative with peritoneal drainage, -52.4 ± 71.6 versus +2.0 ± 50.6 (P = .04). On subset analysis, fluid balance at 48 hours in patients with AVSD was more negative with peritoneal drainage as compared to pleural, -82 ± 51 versus -1 ± 38 mL/kg, respectively (P = .02). Fluid balance at 48 hours in patients with TOF was not significantly different between study groups. Passive peritoneal drainage may more effectively facilitate negative fluid balance when compared to pleural drainage after pediatric cardiac surgery, although this benefit is not likely universal but rather dependent on the patient's underlying physiology. © The Author(s) 2014.

    Endoscopic ultrasound-guided drainage is a minimally invasive first-line modality for the drainage of pancreatic fluid collection (PFC) resulting in a shorter hospital stay and less morbidity compared with surgical cystogastrostomy. Our aim is to evaluate potential differences in the outcomes of endoscopic ultrasound (EUS) guided transmural drainage (EUS-TD) drainage of pancreatic pseudocyst (PP) and walled-off necrosis (WON). We retrospectively reviewed 100 consecutive EUS-guided drainages of PFC utilising EUS reports; clinical notes and imaging with follow-up (FU) to 12 months. All procedures were undertaken under conscious sedation with EUS guidance alone (without fluoroscopy) and placement of plastic double pigtail stents. In these 100 sequential cases, there were 78 cases of PP and 22 cases of WON. All 22/22(100%) cases of WON had successful EUS-guided stent placement. In 2/22(9%), there was little or no clinical improvement. These two patients required further computed tomography (CT)-guided drainage and one of these patients (1/22) (4.5%) developed recurrence within 12 months FU after removal of stents. In case of PP, overall stent placement was successful in 76/78 (97%) patients, but 6/78(8%) required 2nd EUS procedure after failure to show clinical improvement; 3/78(2.5%) required further CT-guided drainage. The overall complication rate was 9%(9/100) with 4%(4/100) requiring endoscopic or CT-guided intervention with no overall 30-day mortality. This is the largest series from a single UK centre demonstrating that EUS-guided cystogastrostomy of PFC drainage using plastic double pigtail stents is sufficient in majority of cases with PFC including that of WON, with or without infection.

    Globalisation has brought new possibilities for international growth in education and professional mobility among healthcare professionals. There has been a noticeable increase of international degree programmes in non-English speaking countries in Europe, creating clinical learning challenges for healthcare students. The aim of this systematic review was to describe mentors' experiences of international healthcare students' learning in a clinical environment. The objective of the review was to identify what influences the success or failure of mentoring international healthcare students when learning in the clinical environment, with the ultimate aim being to promote optimal mentoring practice. A systematic review was conducted according to the guidelines of the Centre for Reviews and Dissemination. Seven electronic databases were used to search for the published results of previous research: CINAHL, Medline Ovid, Scopus, the Web of Science, Academic Search Premiere, Eric, and the Cochrane Library. Search inclusion criteria were planned in the PICOS review format by including peer-reviewed articles published in any language between 2000 and 2014. Five peer-reviewed articles remained after the screening process. The results of the original studies were analysed using a thematic synthesis. The results indicate that a positive intercultural mentor enhanced reciprocal learning by improving the experience of international healthcare students and reducing stress in the clinical environment. Integrating international healthcare students into work with domestic students was seen to be important for reciprocal learning and the avoidance of discrimination. Many healthcare students were found to share similar experiences of mentoring and learning irrespective of their cultural background. However, the role of a positive intercultural mentor was found to make a significant difference for international students: such mentors advocated and mediated cultural differences and

    Full Text Available Introduction Prior work links empathy and positive physician-patient relationships to improved healthcare outcomes. The objective of this study was to analyze a patient experience simulation for emergency medicine (EM interns as a way to teach empathy and conscientious patient care. Methods We conducted a qualitative descriptive study on an in situ, patient experience simulation held during EM residency orientation. Half the interns were patients brought into the emergency department (ED by ambulance and half were family members. Interns then took part in focus groups that discussed the experience. Data collected during these focus groups were coded by two investigators using a grounded theory approach and constant comparative methodology. Results We identified 10 major themes and 28 subthemes in the resulting qualitative data. Themes were in three broad categories: the experience as a patient or family member in the ED; application to current clinical practice; and evaluation of the exercise itself. Interns experienced firsthand the physical discomfort, emotional stress and confusion patients and families endure during the ED care process. They reflected on lessons learned, including the importance of good communication skills, frequent updates on care and timing, and being responsive to the needs and concerns of patients and families. All interns felt this was a valuable orientation experience. Conclusion Conducting a patient experience simulation may be a practical and effective way to develop empathy in EM resident physicians. Additional research evaluating the effect of participation in the simulation over a longer time period and assessing the effects on residents’ actual clinical care is warranted.

    Full text: Mammary lymphoscintigraphy using small volume (0.1-0.2 ml) peritumoral injections of 99 Tc m -antimony sulphide colloid provided a map of the lymph drainage of a breast cancer to its draining sentinel lymph nodes in 92 of 102 patients (over 90%). Non-migration of tracer is reduced by post-injection massage for 5 min but may occur especially if the lymphatics are blocked by metastases. Drainage included the axilla in 92%, internal mammary nodes in 43%, supraclavicular nodes in 12% and intramammary interval nodes in 10% of patients. One patient drained to an interpectoral node. Drainage across the centre-line of the breast occurred in 46% of patients but direct drainage to the contralateral side of the patient was not seen. Lymphatic drainage occurred to 1 node field in 52 patients, 2 node fields in 34 patients and 3 node fields in 6 patients, so that 43% of patients had multiple draining node fields. Drainage to non-axillary sites occurred in 51% of patients. In conclusion, mammary lymphoscintigraphy accurately maps sentinel node location in breast cancer. Approximately half of the patients will have sentinel nodes outside the axilla. To achieve complete lymph node staging in patients with breast cancer, it is logical to biopsy these non-axillary sentinel nodes as well as the sentinel nodes in the axilla. Failure to do so will potentially understage the node status in 50% of patients

    2002-01-01

    Equatorial Energy Inc. is a small Canadian company that has succeeded in the international world of oil exploration and production. The 5 year old company has grown from zero to 13,000 boe/d through its engagement in the acquisition, exploration and development of petroleum and natural gas in Western Canada and Indonesia. Finding costs are getting higher as domestic sedimentary basins mature. This results in higher decline rates and fewer opportunities for growth. However, the international energy sector has become more accessible to small- and medium-sized companies due to the removal of political barriers and better access to new technologies. The support of capital markets and international experience also contributes to greater success in accessing the international energy sector. 16 figs

  12. Properties of the subglacial till inferred from supraglacial lake drainage

    Science.gov (United States)

    Neufeld, J. A.; Hewitt, D.

    2017-12-01

    The buildup and drainage of supraglacial lakes along the margins of the Greenland ice sheet has been previously observed using detailed GPS campaigns which show that rapid drainage events are often preceded by localised, transient uplift followed by rapid, and much broader scale, uplift and flexure associated with the main drainage event [1,2]. Previous models of these events have focused on fracturing during rapid lake drainage from an impermeable bedrock [3] or a thin subglacial film [4]. We present a new model of supraglacial drainage that couples the water flux from rapid lake drainage events to a simplified model of the pore-pressure in a porous, subglacial till along with a simplified model of the flexure of glacial ice. Using a hybrid mathematical model we explore the internal transitions between turbulent and laminar flow throughout the evolving subglacial cavity and porous till. The model predicts that an initially small water flux may locally increase pore-pressure in the till leading to uplift and a local divergence in the ice velocity that may ultimately be responsible for large hydro-fracturing and full-scale drainage events. Furthermore, we find that during rapid drainage while the presence of a porous, subglacial till is crucial for propagation, the manner of spreading is remarkably insensitive to the properties of the subglacial till. This is in stark contrast to the post-drainage relaxation of the pore pressure, and hence sliding velocity, which is highly sensitive to the permeability, compressibility and thickness of subglacial till. We use our model, and the inferred sensitivity to the properties of the subglacial till after the main drainage event, to infer the properties of the subglacial till. The results suggest that a detailed interpretation of supraglacial lake drainage may provide important insights into the hydrology of the subglacial till along the margins of the Greenland ice sheet, and the coupling of pore pressure in subglacial till

    2011-09-01

    Since the International Conference on Nuclear Criticality Safety (ICNC) 2007, the International Criticality Safety Benchmark Evaluation Project (ICSBEP) and the International Reactor Physics Experiment Evaluation Project (IRPhEP) have continued to expand their efforts and broaden their scope. Eighteen countries participated on the ICSBEP in 2007. Now, there are 20, with recent contributions from Sweden and Argentina. The IRPhEP has also expanded from eight contributing countries in 2007 to 16 in 2011. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Criticality Safety Benchmark Experiments1' have increased from 442 evaluations (38000 pages), containing benchmark specifications for 3955 critical or subcritical configurations to 516 evaluations (nearly 55000 pages), containing benchmark specifications for 4405 critical or subcritical configurations in the 2010 Edition of the ICSBEP Handbook. The contents of the Handbook have also increased from 21 to 24 criticality-alarm-placement/shielding configurations with multiple dose points for each, and from 20 to 200 configurations categorized as fundamental physics measurements relevant to criticality safety applications. Approximately 25 new evaluations and 150 additional configurations are expected to be added to the 2011 edition of the Handbook. Since ICNC 2007, the contents of the 'International Handbook of Evaluated Reactor Physics Benchmark Experiments2' have increased from 16 different experimental series that were performed at 12 different reactor facilities to 53 experimental series that were performed at 30 different reactor facilities in the 2011 edition of the Handbook. Considerable effort has also been made to improve the functionality of the searchable database, DICE (Database for the International Criticality Benchmark Evaluation Project) and verify the accuracy of the data contained therein. DICE will be discussed in separate papers at ICNC 2011. The status of the

    A variety of critical experiments were constructed of enriched uranium metal (oralloy ) during the 1960s and 1970s at the Oak Ridge Critical Experiments Facility (ORCEF) in support of criticality safety operations at the Y-12 Plant. The purposes of these experiments included the evaluation of storage, casting, and handling limits for the Y-12 Plant and providing data for verification of calculation methods and cross-sections for nuclear criticality safety applications. These included solid cylinders of various diameters, annuli of various inner and outer diameters, two and three interacting cylinders of various diameters, and graphite and polyethylene reflected cylinders and annuli. Of the hundreds of delayed critical experiments, only three experimental configurations are described here. They are internal graphite reflected metal uranium assemblies with three different diameter HEU annuli (15-9 inches, 15-7 inches and 13-7 inches). These experiments can be found in Reference 1 and in their associated logbook

    2002-01-01

    The OECD/NEA Nuclear Science Committee (NSC) has identified the need to establish international databases containing all the important experiments that are available for sharing among the specialists. The NSC has set up or sponsored specific activities to achieve this. The aim is to preserve them in an agreed standard format in computer accessible form, to use them for international activities involving validation of current and new calculational schemes including computer codes and nuclear data libraries, for assessing uncertainties, confidence bounds and safety margins, and to record measurement methods and techniques. The databases so far established or in preparation related to nuclear data validation cover the following areas: SINBAD - A Radiation Shielding Experiments database encompassing reactor shielding, fusion blanket neutronics, and accelerator shielding. ICSBEP - International Criticality Safety Benchmark Experiments Project Handbook, with more than 2500 critical configurations with different combination of materials and spectral indices. IRPhEP - International Reactor Physics Experimental Benchmarks Evaluation Project. The different projects are described in the following including results achieved, work in progress and planned.

    This paper examines the experiences of nursing students undertaking an international placement during their pre-registration education. The study took place in two schools--one in the United Kingdom, and one in Sweden. The move of nursing education into higher education enabled students to participate in international exchange programmes. Previous research demonstrates that students participating in such programmes may gain enhanced cultural awareness and experience personal and professional growth. The study comprised a multiple case study, utilising semi-structured individual and group interviews and documentary analysis. Eighteen students from the UK and 14 from Sweden participated. Participants described an increase in confidence, self-reliance and professional knowledge and skills resulting from their international placement. There was an awareness of how healthcare roles differ between countries and a change in attitudes to others from different backgrounds and cultures. The differences between the two cases were marginal. Whilst there was support from both home and host universities this varied between the international placement providers. The international placements were beneficial; however, there is a need for change in the preparation, support and monitoring of students, greater engagement with the partner institutions, and more effective mentoring of staff.

  20. Warnings on alcohol containers and advertisements: international experience and evidence on effects.

    Wilkinson, Claire; Room, Robin

    2009-07-01

    In light of possible introduction of alcohol warning labels in Australia and New Zealand, this paper discusses the international experience with and evidence of effects of alcohol warning labels. The report describes international experience with providing information and warnings concerning the promotion or sale of alcoholic beverages, and considers the evidence on the effects of such information and warnings. The experience with and evaluations of the effects of tobacco warning labels are also considered. The most methodologically sound evaluations of alcohol warning labels are based on the US experience. Although these evaluations find little evidence that the introduction of the warning label in the USA had an impact on drinking behaviour, there is evidence that they led to an increase in awareness of the message they contained. In contrast, evaluations of tobacco warning labels find clear evidence of effects on behaviour. There is a need and opportunity for a rigorous evaluation of the impacts of introducing alcohol warning labels to add to the published work on their effectiveness. The experience with tobacco labels might guide the way for more effective alcohol warning labels. Alcohol warning labels are an increasingly popular alcohol policy initiative. It is clear that warning labels can be ineffective, but the tobacco experience suggests that effective warning labels are possible. Any introduction of alcohol warning labels should be evaluated in terms of effects on attitudes and behaviour.

    The Alpha Magnetic Spectrometer (AMS) is a detector designed to operate in space to search for antimatter components in cosmic ray, the annihilation products of darkmatter and to study the antiprotons, positrons and light nuclei. A 'baseline' version of the experiment has successfully completed the precursor flight on Space Shuttle Discovery (June 2-12, 1998). The complete AMS is programmed for installation on International Space Station in year 2003 for an operational period of 3 years. In this contribution we report on the experimental configuration of AMS that will be installed on International Space Station.

    Full Text Available The harmonization of proteomics experiments facilitates the exchange and comparison of results. The definition of standards and metrics ensures reliable and consistent data quality. An internal quality control procedure was developed to assess the different steps of a proteomic analysis workflow and perform a system suitability test. The method relies on a straightforward protocol using a simple mixture of exogenous proteins, and the sequential addition of two sets of isotopically labeled peptides added to reference samples. This internal quality control procedure was applied to plasma samples to demonstrate its easy implementation, which makes it generic for most proteomics applications.

  3. Evaluation of Critical Parameters to Improve Slope Drainage System

    2017-01-01

    Full Text Available This study focuses on identifying and evaluating critical parameters of various drainage configurations, arrangement, and filter which affect the efficiency of water draining system in slopes. There are a total of seven experiments with different types of homogeneous soil, drainage envelope, filter material, and quantity of pipes performed utilizing a model box with a dimension of 0.8 m × 0.8 m × 0.6 m. The pipes were orientated at 5 degrees from the horizontal. Rainfall event was introduced via a rainfall simulator with rainfall intensity of 434.1 mm/h. From the experiments performed, the expected outcomes when utilizing double pipes and geotextile as envelope filter were verified in this study. The results obtained from these experiments were reviewed and compared with Chapter 14 “Subsurface Drainage Systems” of DID’s Irrigation and Agricultural Drainage Manual of Malaysia and the European standard. It is recommended that the pipe installed in the slope could be wrapped with geotextile and in tandem with application of granular filter to minimize clogging without affecting the water discharge rate. Terzaghi’s filter criteria could be followed closely when deciding on new materials to act as aggregate filter. A caging system could be introduced as it could maintain the integrity of the drainage system and could ease installation.

    2005-01-01

    As a result of European Directives 96/92 and 2003/54 on the liberalisation of the internal market for electricity, the Italian electricity sector has been subject to extensive institutional changes which have affected the competitive nature of the market. In this paper we attempt to assess the likely effect of these institutional changes on the Italian electricity industry, and focus particularly on the impact of the introduction of a centralised wholesale market. The assessment of the likely impact of these institutional changes is based on the comparison with the international experience of countries where extensive liberalisation measures have been implemented (such as the US, UK and the Scandinavian region). On the basis of this international comparison, we draw some lessons about how to promote effective competition in the Italian market and in other electricity markets which have not been fully liberalised.

    At present, there is an urgent need to preserve integral reactor physics experimental data including separate or special effects data for nuclear energy and technology applications and the knowledge and competence contained therein. The International Reactor Physics Evaluation Project (IRPhEP) was initiated as a pilot activity in 1999 by the Organization of Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). The project was endorsed as an official activity of the NSC in June of 2003. While coordination and administration of the IRPhEP takes place at an international level, each participating country is responsible for the administration, technical direction, and priorities of the project within their respective countries. This document outlines the general presentation guidelines that evaluators should follow for the description of the experiments and all relevant experimental data in order to ensure the consistency between the evaluations published in the final Handbook. Publication templates will be used to ensure this consistency and will follow the general scheme below: 1 - Experiment identification number; 2- Date; 3 - Name of experiment (Purpose of experiment, Phenomena measured and scope); 4 - Name or designation of experimental programme; 5 - Description of facility; 6 - Description of test or experiment (Experimental configuration, Core life cycle, Experimental limitations or shortcomings); 7 - Phenomena measured (Description of results and analysis, Special features and characteristics of experiment, Measurement systems/methods and uncertainties); 8 - Duplicate or complementary experiments / other related experiments; 9 - Status of completion of the evaluation; 10 - References (pointer to evaluation, archive if available, otherwise generic bibliographic reference); 11 - Authors/ organisers 12 - Material available

    The Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) mission will extend the SAGE data record from the ideal vantage point of the International Space Station (ISS). The ISS orbital inclination is ideal for SAGE measurements providing coverage between 70 deg north and 70 deg south latitude. The SAGE data record includes an extensively validated data set including aerosol optical depth data dating to the Stratospheric Aerosol Measurement (SAM) experiments in 1975 and 1978 and stratospheric ozone profile data dating to the Stratospheric Aerosol and Gas Experiment (SAGE) in 1979. These and subsequent data records, notably from the SAGE II experiment launched on the Earth Radiation Budget Satellite in 1984 and the SAGE III experiment launched on the Russian Meteor-3M satellite in 2001, have supported a robust, long-term assessment of key atmospheric constituents. These scientific measurements provide the basis for the analysis of five of the nine critical constituents (aerosols, ozone (O3), nitrogen dioxide (NO2), water vapor (H2O), and air density using O2) identified in the U.S. National Plan for Stratospheric Monitoring. SAGE III on ISS was originally scheduled to fly on the ISS in the same timeframe as the Meteor-3M mission, but was postponed due to delays in ISS construction. The project was re-established in 2009.

  9. Experience with nuclear safety standards development in non-governmental international organizations

    International Nuclear Information System (INIS)

    Becker, K.

    1985-01-01

    Besides the IAEA as a 'governmental' organization dealing with basic safety recommendations addressed primarily to the national regulatory bodies in developing countries, two closely related non-governmental international standards organizations have gained extensive experience in the field of nuclear standardization. Over more than 25 years since their formation, both (a) the International Organization for Standardization's (ISO) Technical Committee 85 'Nuclear Energy', in particular in its Sub-Committee 3 'Reactor Technology and Safety' and (b) the International Electrotechnical Commission's (IEC) Technical Committee 45 'Nuclear Instrumentation' have published numerous standards. A brief review is given of these, draft standards, and other documents planned to become international standards. Many of them deal with rather specialized topics typical for 'industrial' standards such as standardized procedures, instruments, methods, materials, test methods, terminology, and signs and symbols, but others are directly related to more basic safety issues. In some areas such as quality assurance, seismic aspects of siting and terminology, there has been in the past occasional overlap in the activities of the NUSS programme, IEC and ISO. Letters of Understanding have since 1981 contributed to clarifying the borderlines and to avoiding redundant efforts. Also, some experiences and problems are described arising, for example, from the harmonization of different national safety philosophies and traditions into universally accepted international standards, and the transfer of international standards into national standards systems. Finally, based on a recent comprehensive compilation of some 3300 nuclear standards and standards projects, an attempt is made to present a cost/benefit analysis and an outlook on future developments.

  11. The Voluntariat: A Freirean framework to understand the nature of undergraduate international (medical experiences

    Directory of Open Access Journals (Sweden)

    Seemi Qaiser

    2016-12-01

    Full Text Available Despite literature documenting limited and asymmetrical benefits along with ethical issues, short-term international volunteering is increasingly popular among North American university students as a perceived advantage when applying to professional healthcare schools or the job market. Academic institutions are also encouraging students to pursue international experiences in order to cultivate values as global citizens. These experiences are most typically limited to economically privileged students. Furthermore, international activities in developing countries often lack a pedagogy of social justice and may confirm a simplistic understanding of development. Brazilian educator Paulo Freire’s “liberation pedagogy” provides a framework for understanding the limitations of international volunteering, whereby the presence of privileged volunteers implementing Western models of development may hinder aspects of local movements. Regardless, university students face intense competition in accessing opportunities, such as medical school, and pay large sums to participate in volunteering to strengthen their academic credentials. We propose that these students form “the voluntariat.” They simultaneously play two roles by, first, contributing to the conditions that oppress the very communities in which they volunteer and, second, by playing a role as objects of oppression by the liberal institutions of learning and employment to which they are attempting to gain access.

    2010-01-01

    The International Reporting System for Operating Experience (IRS) is an international system jointly operated by the International Atomic Energy Agency (IAEA) and the OECD Nuclear Energy Agency (OECD/NEA). The fundamental objective of the IRS is to contribute to improving the safety of commercial nuclear power plants which are operated worldwide. This objective can be achieved by providing timely and detailed information on lessons learned from operating and construction experience at the international level. This information could be related to issues and events that are related to safety. The purpose of these guidelines is to describe the system and to give users the necessary background and guidance to enable them to produce IRS reports meeting a high standard of quality while retaining the effectiveness of the system expected by all Member States operating nuclear power plants. As this system is owned by the Member States, the IRS Guidelines have been developed and approved by the IRS National Co-ordinators with the assistance of both Secretariats (IAEA/NEA).

  13. The Voluntariat: A Frieirean framework to understand the nature of undergraduate international (medical) experiences.

    Despite literature documenting limited and asymmetrical benefits along with ethical issues, short-term international volunteering is increasingly popular among North American university students as a perceived advantage when applying to professional healthcare schools or the job market. Academic institutions are also encouraging students to pursue international experiences in order to cultivate values as global citizens. These experiences are most typically limited to economically privileged students. Furthermore, international activities in developing countries often lack a pedagogy of social justice and may confirm a simplistic understanding of development. Brazilian educator Paulo Freire's "liberation pedagogy" provides a framework for understanding the limitations of international volunteering, whereby the presence of privileged volunteers implementing Western models of development may hinder aspects of local movements. Regardless, university students face intense competition in accessing opportunities, such as medical school, and pay large sums to participate in volunteering to strengthen their academic credentials. We propose that these students form "the voluntariat." They simultaneously play two roles by, first, contributing to the conditions that oppress the very communities in which they volunteer and, second, by playing a role as objects of oppression by the liberal institutions of learning and employment to which they are attempting to gain access.

    Intern support groups have been instituted in many residency programs to improve resident well-being. In this article, we discuss the themes that emerged in intern support group meetings in a family medicine program operating in a setting of war and political instability. We held support groups, led by a family physician and a psychologist, that met monthly. Participants were residents in the family medicine program at the American University of Beirut. These residents began their training days after the commencement of the 34-day war between Israel and Hizbollah in 2006. Themes and issues discussed by the residents were noted and are reported in this article. We found that despite the stressors of the political situation, our interns focused on the usual stress of internship, such as the difficulties of functioning as interns in other departments and dealing with the time demands of internship as their main sources of stress at the beginning of internship. The stresses associated with the war did not emerge in the group until later in the year. These included tension with patients and political confrontations with staff, as well as personal struggles with the lack of political stability and depressed mood. This paper serves to share our experience and highlight some areas of concern that residents experience when training in a country or region that is at war.

    Full Text Available Background: In 2010 a community of practice was set up for and by doctoral students engaged in person-centred and practitioner research. After three years, this community became part of a larger international community of practice. Aims and objectives: Captured under the stanzas of a poem and supported by the literature, this paper uses member narratives and creative expressions in a critical reflection on the experience of being a member of the Student International Community of Practice. Conclusions: Membership in the community of practice was experienced as beneficial, providing both support and challenge to enrich the doctoral students’ development as person-centred researchers. Retaining connectivity across an international landscape and finding effective ways to integrate new members into the community presented the greatest challenges. Implications for practice development: • The theoretical foundation and experiential knowledge could assist others considering support structures for the development of person-centred practices • Shared learning and co-creation of knowledge add value to the experience of being a doctoral researcher • Membership fluctuations present challenges to continuity of learning and the maintenance of a safe space with communities of practice. Such fluctuations, however, create chances for community members to experience diverse roles within the group and encourage explicit attention to person-centredness

    Despite the great influence International Medical Experiences (IMs) can have on young physicians and their impact on patients and communities, they are not offered in all training programs and are at risk of being reduced in some due to stringent guidelines for funding of graduate medical education. IMs provide unique experiences in clinical, epidemiologic, cultural, and political arenas. From an educational perspective, they broaden a physician's differential diagnostic skills and introduce clinical entities rarely seen in the U.S. Time spent in developing countries emphasizes the importance of community health and increases cultural and linguistic competence. Experience working with the underserved during an IM has been shown to increase interest in volunteerism, humanitarian efforts, and work with underserved populations both in the US and abroad. IMs also afford physicians the opportunity to learn about the delivery of health care abroad and are associated with an increase in primary care specialty choice. It is time for the leaders in graduate medical education to prioritize international health opportunities. Leaders in academic medicine can press for changes in reimbursement patterns at the national level or special funds for international electives. Hospitals can set up separate accounts to help finance resident salaries and benefits while abroad. Individual departments must be flexible with resident schedules to allow elective time. Medical students and housestaff can organize and lobby larger organizations such as the American Medical Association (AMA), the American Association of Medical Colleges (AAMC), and specialty groups to make IMs universally accessible.

    Internal tides are suggested to play a major role in the sustaining of the global oceanic circulation [1][5]. Although the exact origin of the energy conversions occurring in stratified fluids is questioned [2], it is clear that the diapycnal energy transfers provided by the energy cascade of internal gravity waves generated at tidal frequencies in regions of steep bathymetry is strongly linked to the general circulation energy balance. Therefore a precise quantification of the energy supply by internal waves is a crucial step in forecasting climate, since it improves our understanding of the underlying physical processes. We focus on an academic case of internal waves generated over an oceanic ridge in a linearly stratified fluid. In order to accurately quantify the diapycnal energy transfers caused by internal waves dynamics, we adopt a complementary approach involving both laboratory and numerical experiments. The laboratory experiments are conducted in a 4m long tank of the CNRM-GAME fluid mechanics laboratory, well known for its large stratified water flume (e.g. Knigge et al [3]). The horizontal oscillation at precisely controlled frequency of a Gaussian ridge immersed in a linearly stratified fluid generates internal gravity waves. The ridge of e-folding width 3.6 cm is 10 cm high and spans 50 cm. We use PIV and Synthetic Schlieren measurement techniques, to retrieve the high resolution velocity and stratification anomaly fields in the 2D vertical plane across the ridge. These experiments allow us to get access to real and exhaustive measurements of a wide range of internal waves regimes by varying the precisely controlled experimental parameters. To complete this work, we carry out some direct numerical simulations with the same parameters (forcing amplitude and frequency, initial stratification, boundary conditions) as the laboratory experiments. The model used is a non-hydrostatic version of the numerical model Symphonie [4]. Our purpose is not only to

    Full Text Available The growing attention placed on experiences can be regarded as a mega-trend, and has given currency to the proposition that experiences are important for consumer’s self-perception and satisfaction with a specific visit. In order to assess this assumption, this study empirically examines the applicability of Pine and Gilmore’s ‘experience economy’ concept and examines the impact of its four dimensions i.e., education, escapism, esthetics, and entertainment on delegates’ satisfaction and behavioural intentions. Based on convenience sampling, 210 questionnaires are distributed to the delegates of 2 international academic conferences out of which 188 were deemed fit for further analysis 89% response rate. The results indicate that Pine and Gilmore’s model can further our understanding of the experience market. However, the findings in contrast with previous studies show that different experiential dimensions influence the delegates’ overall satisfaction in different contexts. For instance, the dimension of education has a relatively higher significant effect on the delegates’ overall satisfaction and behavioural intentions in the context of international academic conferences. The theoretical and practical implications of this study are also discussed.

  2. Experience of International Education of East Asian Students in English-speaking Countries: A four-dimensional approach

    2017-07-01

    Full Text Available Global participation in international education in the last two decades has increased exponentially. International students face difficulties in adjusting to the culture of their host country due to their unique needs (Bertram, Poulakis, Elsasser & Kumar, 2014. This article presents themes comprising the international education phenomenon involving the experiences of East Asian international students in English-speaking countries. The literature reviewed for this article pertains to many aspects of international education, covering the factors that influence the decision to embark on the international education journey to the adjustment experienced by students to the host culture. The authors suggest that the international education experience is comprised of four dimensions: structural, linguistic, internal, and external. We also posit that Confucianism, which many East Asian students follow, influences not only the psycho-social dimension of the international education experience but also their instructional preferences within the structural dimension. We further contend that students’ actual and perceived proficiency (or the lack thereof in the host country’s language greatly shapes all aspects of the student’s international education experience, which then determines the degree of acculturative stress involved and plays a key role in each of the three dimensions. Because of the anticipated continued growth in the number of international students from East Asia attending higher education institutions in English-speaking countries such as the United States, Australia, Canada, and parts of Africa, it is important to examine how each of the dimensions proposed impact each other. Approaching the study of the international education experience one dimension at a time, as many scholars have done, does not completely address all of the unique needs of international students. We suggest that research in this area be conducted holistically by

    With more than 25 years of experience in the development of reactor vessel internals segmentation and packaging technology, Westinghouse has accumulated significant know-how in the reactor dismantling market. Building on tooling concepts and cutting methodologies developed decades ago for the successful removal of nuclear fuel from the damaged Three Mile Island Unit 2 reactor (TMI-2), Westinghouse has continuously improved its approach to internals segmentation and packaging by incorporating lessons learned and best practices into each successive project. Westinghouse has developed several concepts to dismantle reactor internals based on safe and reliable techniques, including plasma arc cutting (PAC), abrasive water-jet cutting (AWJC), metal disintegration machining (MDM), or mechanical cutting. Westinghouse has applied its technology to all types of reactors covering Pressurized Water Reactors (PWR's), Boiling Water Reactors (BWR's), Gas Cooled Reactors (GCR's) and sodium reactors. The primary challenges of a segmentation and packaging project are to separate the highly activated materials from the less-activated materials and package them into appropriate containers for disposal. Since space is almost always a limiting factor it is therefore important to plan and optimize the available room in the segmentation areas. The choice of the optimum cutting technology is important for a successful project implementation and depends on some specific constraints like disposal costs, project schedule, available areas or safety. Detailed 3-D modeling is the basis for tooling design and provides invaluable support in determining the optimum strategy for component cutting and disposal in waste containers, taking account of the radiological and packaging constraints. Westinghouse has also developed a variety of special handling tools, support fixtures, service bridges, water filtration systems, video-monitoring systems and customized rigging, all of which are required for a

    From the very beginning nuclear energy appeared as a fruitful field for international co-operation and particularly for international projects and joint ventures. By pooling scientific, technical and financial resources, the participating countries sought to promote the development of technology and the transition of nuclear energy to the industrial stage. Governments and therefore intergovernmental organizations were the driving force behind the establishment of joint projects in various R and D sectors, often in association with industry and private research institutes. The situation changed considerably from the end of the 1960s onwards. Despite some remarkable technical achievements, international co-operation did not develop to the extent predicted at the outset. Industry took over in the exploitation of proven technologies, and industrial co-operation agreements have become an important feature in some key areas of nuclear energy. This trend raises questions as to the future of joint R and D projects organized through intergovernmental co-operation. Although such projects are still very useful, they tend to be concentrated in those few sectors which continue to be of direct interest to the Governments; for instance, fundamental research, radioactive waste management and nuclear safety. The position of nuclear energy has changed, and the benefits to be drawn from this form of international co-operation must be critically re-assessed accordingly. While advantage to be gained from international projects for countries which are the most advanced in the development of nuclear energy is not the same as it was at the beginning, the transfer of experience and knowledge to less advanced countries is still the main concern of projects dealing with safety and regulatory matters. The experience thus gained provides a very useful insight into the legal and institutional framework of joint projects

    This qualitative study explored the cultural adjustment experiences of 15 Asian Indian, Japanese, Korean, and Vietnamese international college women through semistructured interviews. By using consensual qualitative research methodology (C. E. Hill, B. J. Thompson, & E. N. Williams, 1997), 6 primary domains or themes related to these women's cultural adjustment experiences were identified via data analysis: their feelings and thoughts about living in the United States, perceived differences between their country of origin and the United States, their English language acquisition and use, their prejudicial or discriminatory experiences in the United States, their peer and family networks, and their strategies for coping with cultural adjustment problems. Implications of the findings for mental health practice are discussed. Copyright (c) 2005 APA, all rights reserved.

    A series of experiments have been carried out in 2008 at JT-60U and JET to find common characteristics and explain differences between internal transport barriers (ITBs). The identity experiments succeeded in matching the profiles of most dimensionless parameters at the time ITBs were triggered. Thereafter the q-profile development deviated due to differences in non-inductive current density profile, affecting the ITB. Furthermore, the ITBs in JET were more strongly influenced by the H-mode pedestal or edge localized modes. It was found to be difficult to match the plasma rotation characteristics in both devices. However, the wide range of Mach numbers obtained in these experiments shows that the rotation has little effect on the triggering of ITBs in plasmas with reversed magnetic shear. On the other hand the toroidal rotation and more specifically the rotational shear had an impact on the subsequent growth and allowed the formation of strong ITBs.

    The internal jugular veins are considered to be the main pathways of cerebral blood drainage. However, angiographic and anatomical studies show a wide anatomical variability and varying degrees of jugular and non-jugular venous drainage. The study systematically analyses the types and prevalence of human cerebral venous outflow patterns by ultrasound and MRI. Fifty healthy volunteers (21 females; 29 males; mean age 27±7 years) were studied by color-coded duplex sonography. Venous blood volume flow was measured in both internal jugular and vertebral veins in the supine position. Furthermore, the global arterial cerebral blood volume flow was calculated as the sum of volume flows in both internal carotid and vertebral arteries. Three types of venous drainage patterns were defined: a total jugular volume flow of more than 2/3 (type 1), between 1/3 and 2/3 (type 2) and less than 1/3 (type 3) of the global arterial blood flow. 2D TOF MR-venography was performed exemplarily in one subject with type-1 and in two subjects with type-3 drainage. Type-1 drainage was present in 36 subjects (72%), type 2 in 11 subjects (22%) and type 3 in 3 subjects (6%). In the majority of subjects in our study population, the internal jugular veins were indeed the main drainage vessels in the supine body position. However, a predominantly non-jugular drainage pattern was found in approximately 6% of subjects. (orig.)

  11. Learning in an Online Distance Education Course: Experiences of Three International Students

    Directory of Open Access Journals (Sweden)

    Zuochen Zhang

    2010-03-01

    Full Text Available This case study explores the learning experiences of three international students who were enrolled in an online master’s program offered by a large university in Canada. The aim of the study was to understand the international students’ experiences with, and perspectives on, the online learning environment. Findings indicate that previous education and especially language proficiency strongly impacted the learning of these students in this environment. Non-native English speakers required considerably more time to process readings and postings and to make postings themselves. Their lack of familiarity with the details of North American culture and colloquial language made it difficult to follow much of the course discussion. They also tended to avoid socializing in the course, which left them at the periphery of course activities. Based on these findings, the authors make the following recommendations for designers and instructors of online courses: 1 Raise the English language proficiency requirement for graduate admissions into online programs because the text-based communication in a CMC space requires interpreting messages without non-verbal cues; 2 Ensure that online distance education course designers are aware of the needs and expectations of international students; and 3 Combine the design principles from both traditional and constructivism theories.

    Full Text Available Introduction: the method and way of learning and teaching are effective in acquiring clinical skills, and identifying the shortcomings of learning and teaching will lead to better planning. The purpose of this study was to explain the experiences of the learning clinical procedures of the internal medicine residents in gastroenterology department. Methods: qualitative study using content thematic analysis was done. Six fourth-year residents were selected and interviewed considering purposive sampling. The data of the interviews were transcribed and analyzed after rereading. Results: the collected data are divided into three categories: learning and experience with the following four categories (learning time and experiencing, leaning and experiencing times, learning and experiencing opportunities, training and the lack of the training of some procedures. These categories are explained by using some quotes derived from the data. Conclusion: the results of this study suggest that the administrative management of internal residency is poor and should get seriously in implementation and application of intended instructions existing in the prepared program of Medical Education and Specialized Council of internal residency period. The attending physicians and residents must be aware of the content of education program at the beginning of the residency periods and the trainers must try to supervise the residents’ education.

    Residents experience severely high levels of stress, depression and burnout, leading to perceived medical errors, as well as to symptoms of impairment, such as chronic anger, cognitive impairment, suicidal behavior and substance abuse. Because research has not yet provided a psychometrically robust population-specific tool to measure the level of stress of medicine residents, we aimed at building and validating such a measure. Using an inductive scale development approach, a short, pragmatic measure was built, based on the interviews of 17 medicine residents. The Internal Medicine Residency Stress Scale (IMRSS) was then administered in a sample of 259 internal medicine residents (199 females, 60 males, M Age  = 25.6) along with the Hospital Anxiety and Depression Scale, Maslach Burnout Inventory, Satisfaction With Life Scale and Ways of Coping Checklist. The IMRSS showed satisfactory internal reliability (Cronbach's α = .86), adequate structural validity - studied through Confirmatory Factor Analysis (χ 2 /df = 2.51, CFI = .94; SRMR = .037, RMSEA = .076) - and good criterion validity - the IMRSS was notably strongly correlated with emotional exhaustion (r = .64; p is recommended to quickly and frequently assess and monitor stress among internal medicine residents.

    This report provides a summary of the experimental, analytical, and numerical results of the Capillary Flow Experiment (CFE) performed aboard the International Space Station (ISS). The experiments were conducted in space beginning with Increment 9 through Increment 16, beginning August 2004 and ending December 2007. Both primary and extra science experiments were conducted during 19 operations performed by 7 astronauts including: M. Fincke, W. McArthur, J. Williams, S. Williams, M. Lopez-Alegria, C. Anderson, and P. Whitson. CFE consists of 6 approximately 1 to 2 kg handheld experiment units designed to investigate a selection of capillary phenomena of fundamental and applied importance, such as large length scale contact line dynamics (CFE-Contact Line), critical wetting in discontinuous structures (CFE-Vane Gap), and capillary flows and passive phase separations in complex containers (CFE-Interior Corner Flow). Highly quantitative video from the simply performed flight experiments provide data helpful in benchmarking numerical methods, confirming theoretical models, and guiding new model development. In an extensive executive summary, a brief history of the experiment is reviewed before introducing the science investigated. A selection of experimental results and comparisons with both analytic and numerical predictions is given. The subsequent chapters provide additional details of the experimental and analytical methods developed and employed. These include current presentations of the state of the data reduction which we anticipate will continue throughout the year and culminate in several more publications. An extensive appendix is used to provide support material such as an experiment history, dissemination items to date (CFE publication, etc.), detailed design drawings, and crew procedures. Despite the simple nature of the experiments and procedures, many of the experimental results may be practically employed to enhance the design of spacecraft engineering

    The Energy Foundation's China Sustainable Energy Program (CSEP) has undertaken a major project investigating fiscal and tax policy options for stimulating energy efficiency and renewable energy development in China. This report, which is part of the sectoral sub-project studies on energy efficiency in industry, surveys international experience with tax and fiscal policies directed toward increasing investments in energy efficiency in the industrial sector. The report begins with an overview of tax and fiscal policies, including descriptions and evaluations of programs that use energy or energy-related carbon dioxide (CO2) taxes, pollution levies, public benefit charges, grants or subsidies, subsidized audits, loans, tax relief for specific technologies, and tax relief as part of an energy or greenhouse gas (GHG) emission tax or agreement scheme. Following the discussion of these individual policies, the report reviews experience with integrated programs found in two countries as well as with GHG emissions trading programs. The report concludes with a discussion of the best practices related to international experience with tax and fiscal policies to encourage investment in energy efficiency in industry.

    2018-03-01

    Full Text Available International university students are a growing section of the workforce and are thought to be at greater risk of injury. Qualitative studies have highlighted vulnerabilities, but there is a shortage of quantitative research exploring the injury experience and associated risk factors of this emerging issue. In this study, a total of 466 university student workers across a range of study programs in a single Australian university completed an online survey, with questions relating to their background, working experience, training and injury experience. Risk factors for injury were explored in a multivariate statistical model. More than half had not received any safety training before they started work, and 10% reported having had a work injury. About half of these injuries occurred after training. Statistically significant risk factors for injury included working more than 20 h per week (adjusted odds ratio 2.20 (95% CI 1.03–4.71 and lack of confidence in discussing safety issues (AOR 2.17; 95% CI 1.13–4.16. The findings suggest the need for a more engaging and effective approach to safety education and a limit on working hours. This situation is a moral challenge for universities, in that they are effectively sponsoring young workers in the community. It is recommended that longitudinal studies of international student workers be conducted.

    Materials degradation due to the aging phenomena is one of the key issues for the life assessment and extension of the light water reactors (LWRs). This presentation introduces JAERI`s activities in the field of LWR material researches which utilize the research and testing reactors for irradiation experiments. The activities are including the material studies for the core internals, pressure vessel and fuel cladding. These materials are exposed to the neutron/gamma radiation and high temperature water environments so that it is worth reviewing their degradation phenomena as the continuum. Three topics are presented; For the core internal materials, the irradiation assisted stress corrosion cracking (IASCC) of austenitic stainless steels is the present major concern. At JAERI the effects of alloying elements on IASCC have been investigated through the post-irradiation stress corrosion cracking tests in high-temperature water. The radiation embrittlement of pressure vessel steels is still a significant issue for LWR safety, and at JAERI some factors affecting the embrittlement behavior such as a dose rate have been investigated. Waterside corrosion of Zircaloy fuel cladding is one of the limiting factors in fuel rod performance and an in-situ measurement of the corrosion rate in high-temperature water was performed in JMTR.

    The determination of the hydraulic properties of an alluvial soil in Cajueiro reservoir has been carried out in two experimental plots of 3.5 m x 3.5 m, installed in the opposite banks of the brook in which is located the dam, (Tuparetama Country, Pernambuco). For the determination of the hydraulic conductivity as a function of the soil water volumetric content K({theta}), the internal driainage method proposed by Hillel et al. (1972) has been applied. The soil-water retention curves h ({theta}) have been determined through the experimental data of volumetric water content and pressure obtained in field experiments. The h ({theta}) and K ({theta}) curves have been fitted to van Genuchten's closed - form equations (1980), using the Burdine's model, and Brooks and Corey's model, respectively. The volumetric water content, matric potential, and total water content estimates have been fitted to two analytical functions: one being composed by the addition of three exponentials terms the other composed and by representation the reverse of the power functions. The latter has been preferred due to its smoother representation between the fast and the slow its drainage phases. Considering the hydraulic behavior, three different layers have been identified in the soil profiles of the two experimental parcels A2 and B4 in the alluvial soil Cajueiro reservoir. The second layer of the soil profile in parcel A2 turned out the more pemeable than the other two layers. As to the soil profile in parcel B4, the first layer turned out more conductive than the other layers. However, the biggest volumetric water content variations were due to the differences found in the texture and structure of the soil profiles under study. The hydrodynamic characterization of the two soil profiles, A2 and B4, brings significant elements for the simulation of scenarios related to the soil of water transport processes. It is of particular importance the study of scenarios related to the

    US healthcare facilities have addressed nursing shortages in part by recruiting internationally educated nurses (IENs), and studies suggest IENs may make up a significant percentage of the nursing workforce in urban hospitals. Despite the economic recession of 2008-2012, international nurse migration is expected to continue. Little is known about IENs in the southeastern USA, and no studies have compared their perspectives to those of their US counterparts. The purpose of this study was to gain a deeper understanding about the experiences of IENs compared to those of US registered nurses (RNs) practising in two urban hospitals in southeastern USA. This study involved two rounds of semi-structured interviews of 82 IENs and US RNs. Interviews focused on themes relating to education, barriers to practice, intent to stay in nursing and IENs' migration experiences. Most IENs interviewed migrated to the USA after 1990 to join their family and do not plan to return to their home countries to practise. Most IENs initially received their Associate Degree in Nursing; many have obtained their Bachelor of Science in Nursing degree. IENs and newly licensed US RNs faced similar barriers when they began practising in the USA, but IENs faced additional challenges adjusting to the attitudes of US patients, the perceived lack of respect for nurses and delivering total patient care. IENs would benefit from orientation regarding the cultural differences in the USA. In other ways, their challenges are similar to those of US RNs; policies regarding education, recruitment and retention could target both groups together. © 2013 The Authors.

    Full Text Available The U.S. is fast becoming more culturally diverse, creating a greater need for entry-level occupational therapists to be culturally competent. In order to increase students’ cultural competence, there is a growing support for international service learning (ISL. The purpose of this qualitative research study was to explore the perspectives of occupational therapy practitioners who engaged in ISL as occupational therapy students. Interviews were conducted with nine practicing occupational therapists, all of whom graduated from the same occupational therapy program in the U.S. and participated in an ISL experience in Guatemala. Phenomenological methods were used to analyze the transcribed interviews for codes, categories, and themes. The three themes that emerged were: Participants reported encountering many new experiences that led to experiencing a variety of emotions, their experiences in the Guatemalan culture further contributed to a deeper level of understanding about culture, and all of the participants reported that their ISL experiences allowed them to practice occupational therapy skills and interventions with limited resources, which facilitated creativity and resourcefulness. The findings of this study support that completing ISL as students contributes to occupational therapists’ personal and professional lives and offers a glimpse of potential long-term effects of completing an ISL experience.

    Planning an international practice experience for nursing students is a challenging, but rewarding, opportunity. Kwantlen University College faculty members' experience of planning for 8 Bachelor of Science in Nursing students to study abroad was no exception. Faculty members' and students' interest prompted a request for a placement in Nepal. The faculty members involved in the planning were dedicated to using a process that would enable them to remain true to the program philosophy and theoretical underpinnings throughout the entire experience, from the planning phase to the follow-up presentation. Using Wheatley's theory, the students and faculty members reexamined their personal leadership styles to ensure they remained relationship focused, rather than task focused. Wheatley maintained that because the potentiality lies in building strong relationships, it is important to support the creative power that lies in those involved in a project. This article describes new science leadership and relates it to the planning phase for the practice experience in Nepal. Then, reflections on how the philosophy of the program may have influenced the experience are shared. Finally, critical reflection on using this theory in nursing education is presented.

    This paper is a descriptive account of how short-term international and multicultural experiences can be integrated into early design experiences in an aerospace engineering curriculum. Such approaches are considered as important not only in fostering a student's interest in the engineering curriculum, but also exposing them to a multicultural setting that they are likely to encounter in their professional careers. In the broader sense, this programme is described as a model that can be duplicated in other engineering disciplines as a first-year experience. In this study, undergraduate students from Rensselaer Polytechnic Institute (RPI) and Universidad del Turabo (UT) in Puerto Rico collaborated on a substantial design project consisting of designing, fabricating, and flight-testing radio-controlled model aircraft as a capstone experience in a semester-long course on Fundamentals of Flight. The two-week long experience in Puerto Rico was organised into academic and cultural components designed with the following objectives: (i) to integrate students in a multicultural team-based academic and social environment, (ii) to practise team-building skills and develop students' critical thinking and analytical skills, and finally (iii) to excite students about their engineering major through practical applications of aeronautics and help them decide if it is a right fit for them.

    The goal of this research is to provide durable and long-term water management solutions using exterior insulating sheathing as part of the water management system. It is possible to tape or seal the joints in insulating sheathing to create a drainage plane and even an air control layer. There exists the material durability component of the tape as well as the system durability component being the taped insulating sheathing as the drainage plane. This measure guideline provides best practice and product recommendations from the interviewed contractors and homebuilders who collectively have a vast amount of experience. Three significant issues were discussed with the group, which are required to make taped insulating sheathing a simple, long-term, and durable drainage plane: horizontal joints should be limited or eliminated wherever possible; where a horizontal joint exists use superior materials; and frequent installation inspection and regular trade training are required to maintain proper installation.

    Adolescent girls today suffer from internalizing problems such as somatic symptoms and mental health problems at higher rates compared to those of previous decades, and effective interventions are warranted. The aim of this study was to explore the experiences of participating in an 8-month dance intervention. This qualitative study was embedded in a randomized controlled trial of a dance intervention for adolescent girls with internalizing problems. A total of 112 girls aged 13–18 were included in the study. The dance intervention group comprised 59 girls, 24 of whom were strategically chosen to be interviewed. Data were analyzed using qualitative content analysis with an inductive approach. The experiences of the dance intervention resulted in five generic categories: (1) An Oasis from Stress, which represents the fundamental basis of the intervention; (2) Supportive Togetherness, the setting; (3) Enjoyment and Empowerment, the immediate effect; (4) Finding Acceptance and Trust in Own Ability, the outcome; and (5) Dance as Emotional Expression, the use of the intervention. One main category emerged, Finding Embodied Self-Trust That Opens New Doors, which emphasizes the increased trust in the self and the ability to approach life with a sense of freedom and openness. The central understanding of the adolescent girls’ experiences was that the dance intervention enriched and gave access to personal resources. With the non-judgmental atmosphere and supportive togetherness as a safe platform, the enjoyment and empowerment in dancing gave rise to acceptance, trust in ability, and emotional expression. Taken together, this increased self-trust and they discovered a new ability to “claim space.” Findings from this study may provide practical information on designing future interventions for adolescent girls with internalizing problems.

    1996-01-01

    We described a new ventricular catheter that is the combination of a "classic" ventricular catheter with a piezo-resistive transducer at its tip. The device allows parallel recordings of intraventricular fluid pressure via a chip and a fluid-filled external transducer, drainage of cerebrospinal fluid from the ventricle or injection of fluid into the ventricle with simultaneous monitoring of intracranial pressure, and recording of brain tissue pressure in cases of misplacement or dislocation of the ventricular catheter or in cases of progressively narrowing ventricles caused by brain edema. Clinical tests in various situations at different pressure ranges (total recording time, 1356 h in 13 patients) gave excellent correlations of both pressures. Application of the device is especially indicated in clinical situations in which pressure-controlled drainage is desirable, occlusion of ventricular bolts is likely, or pressure-volume tests are needed.

    Extensive work has been carried out in the field of food irradiation in the GDR and Hungary in recent years. The irradiation of onions for sprout inhibition has reached a commercial stage in the GDR of more than 5,000 tons in 1986. The export of onions is the first example of international trade in irradiated food between socialist countries. Experiences of this trade is presented in the paper. Results of quality control of the bulbs (losses in weight an quality) after an intermediate storage period are discussed. Hungarian consumer reactions to irradiated onions is also evaluated.

    Successful transition to practice of internationally educated nurses (IENs) can critically affect quality of care. The aim of this study was to characterize the facilitators and barriers to transition of Nigerian IENs (NIENs) to the United States health care setting. Using a descriptive phenomenology approach, 6 NIENs were interviewed about their transitional experiences in the United States. Thematic methods were used for data analysis. The three major themes identified from the participants' stories were "fear/anger and disappointment" (FAD), "road/journey to success/overcoming challenges" (RJO), and "moving forward" (MF). The FAD theme predominated, including experiences of racism, bullying, and inequality. The RJO theme included resilience, and the MF theme encompassed personal growth. NIENs face personal and organizational barriers to adaptation, especially fear, anger and disappointment. Future research should seek to develop a model for optimal adaptation that focuses on improving both personal and organizational facilitators and decreasing barriers.

    More efficient methodology for assessing the impact of combined exposures to multiple chemicals has been considered in a project of the World Health Organization (WHO) International Programme on Chemical Safety (IPCS). Recommendations regarding terminology and the status of development of the framework, its content, review and application are described. Evolving experience in its application is illustrated by example (polybrominated diphenyls) with special emphasis on the critical content of problem formulation, the role of predictive tools in grouping of chemicals for consideration and the importance of explicit delineation of relative uncertainty and sensitivity for tiered assessment. Priorities in increasing the efficiency of risk assessment not only for combined exposures, but more generally based on experience acquired in developing the framework and its application in case studies are identified and recommendations included

    This technical note will present simple but widely used methods for the design of drainage systems. The note will primarily deal with surface water (rainwater) which on a satisfactorily way should be transport into the drainage system. Traditional two types of sewer systems exist: A combined system......, where rainwater and sewage is transported in the same pipe, and a separate system where the two types of water are transported in individual pipe. This note will only focus on the separate rain/stormwater system, however, if domestic sewage should be included in the dimensioning procedure, it......’s not major different than described below - just remember to include this contribution for combined systems where the surface water (rain) and sewage are carried in the same pipes in the system and change some of the parameters for failure allowance (this will be elaborated further later on).

    This paper provides an overview of the microgravity fluid physics and transport phenomena experiments planned for the International Spare Station. NASA's Office of Life and Microgravity Science and Applications has established a world-class research program in fluid physics and transport phenomena. This program combines the vast expertise of the world research community with NASA's unique microgravity facilities with the objectives of gaining new insight into fluid phenomena by removing the confounding effect of gravity. Due to its criticality to many terrestrial and space-based processes and phenomena, fluid physics and transport phenomena play a central role in the NASA's Microgravity Program. Through widely publicized research announcement and well established peer-reviews, the program has been able to attract a number of world-class researchers and acquired a critical mass of investigations that is now adding rapidly to this field. Currently there arc a total of 106 ground-based and 20 candidate flight principal investigators conducting research in four major thrust areas in the program: complex flows, multiphase flow and phase change, interfacial phenomena, and dynamics and instabilities. The International Space Station (ISS) to be launched in 1998, provides the microgravity research community with a unprecedented opportunity to conduct long-duration microgravity experiments which can be controlled and operated from the Principal Investigators' own laboratory. Frequent planned shuttle flights to the Station will provide opportunities to conduct many more experiments than were previously possible. NASA Lewis Research Center is in the process of designing a Fluids and Combustion Facility (FCF) to be located in the Laboratory Module of the ISS that will not only accommodate multiple users but, allow a broad range of fluid physics and transport phenomena experiments to be conducted in a cost effective manner.

    2017-01-01

    The International Reactor Physics Evaluation (IRPhE) Project was initiated as a pilot in 1999 by the Nuclear Energy Agency (NEA) Nuclear Science Committee (NSC). The project was endorsed as an official activity of the NSC in June 2003. While the NEA co-ordinates and administers the IRPhE Project at the international level, each participating country is responsible for the administration, technical direction and priorities of the project within their respective countries. The information and data included in this handbook are available to NEA member countries, to all contributing countries and to others on a case-by-case basis. The IRPhE Project is patterned after the International Criticality Safety Benchmark Evaluation Project (ICSBEP). It closely co-ordinates with the ICSBEP to avoid duplication of efforts and publication of conflicting information. Some benchmark data are applicable to both nuclear criticality safety and reactor physics technology. Some have already been evaluated and published by the ICSBEP, but have been extended to include other types of measurements in addition to the critical configuration. Through this effort, the IRPhE Project will be able to 1) consolidate and preserve the existing worldwide information base; 2) retrieve lost data; 3) identify areas where more data are needed; 4) draw upon the resources of the international reactor physics community to help fill knowledge gaps; 5) identify discrepancies between calculations and experiments due to deficiencies in reported experimental data, cross-section data, cross-section processing codes and neutronics codes; 6) eliminate a large amount of redundant research and processing of reactor physics experiment data, and 7) improve future experimental planning, execution and reporting. This handbook contains reactor physics benchmark specifications that have been derived from experiments performed at nuclear facilities around the world. The benchmark specifications are intended for use by

  18. Exploring Agricultural Drainage's Influence on Wetland and ...

    Science.gov (United States)

    Artificial agricultural drainage (i.e. surface ditches or subsurface tile) is an important agricultural management tool. Artificial drainage allows for timely fieldwork and adequate root aeration, resulting in greater crop yields for farmers. This practice is widespread throughout many regions of the United States and the network of artificial drainage is especially extensive in flat, poorly-drained regions like the glaciated Midwest. While beneficial for crop yields, agricultural drains often empty into streams within the natural drainage system. The increased network connectivity may lead to greater contributing area for watersheds, altered hydrology and increased conveyance of pollutants into natural water bodies. While studies and models at broader scales have implicated artificial drainage as an important driver of hydrological shifts and eutrophication, the actual spatial extent of artificial drainage is poorly known. Consequently, metrics of wetland and watershed connectivity within agricultural regions often fail to explicitly include artificial drainage. We use recent agricultural census data, soil drainage data, and land cover data to create estimates of potential agricultural drainage across the United States. We estimate that agricultural drainage in the US is greater than 31 million hectares and is concentrated in the upper Midwest Corn Belt, covering greater than 50% of available land for 114 counties. Estimated drainage values for numerous countie

    We report the design, construction, and performances of a microwave (MW) heating device for laboratory experiments with non-contact, homogeneous internal heating. The device generates MW radiation at 2.47 GHz from a commercial magnetron supplied by a pulsed current inverter using proprietary, feedback based command and control hardware and software. Specially designed MW launchers direct the MW radiation into the sample through a MW homogenizer, devised to even the MW power distribution into the sample's volume. An adjustable MW circuit adapts the MW generator to the load (i.e., the sample) placed in the experiment chamber. Dedicated heatsinks maintain the MW circuits at constant temperature throughout the experiment. Openings for laser scanning for image acquisition with a CCD camera and for the cooling circuits are protected by special MW filters. The performances of the device are analyzed in terms of heating uniformity, long term output power stability, and load matching. The device is used for small scale experiments simulating Earth's mantle convection. The 30 × 30 × 5 cm(3) convection tank is filled with a water‑based viscous fluid. A uniform and constant temperature is maintained at the upper boundary by an aluminum heat exchanger and adiabatic conditions apply at the tank base. We characterize the geometry of the convective regime as well as its bulk thermal evolution by measuring the velocity field by Particle Image Velocimetry and the temperature field by using Thermochromic Liquid Crystals.

    One of the most important problems that have some cities is the urban floods because of poor drainage design. Therefore the systems the drainage do not have the capacity of capture the flow of discharge generated in a rain event and insert it into the drainage network. Even though the two problems that have caught the main attention are the evaluation of the volumes falling in the river basin because extreme rainfall events often lead to urban pluvial flooding being a hydrologic problem and the hydraulic design of the sewer network being a hydraulic problem to limiting capacity of the drainage system, there is an intermediate step between these two processes that is necessary to solve that is the hydraulic behavior of the grate inlet. We need to collect the runoff produced on the city surface and to introduce it in the sewer network. Normally foundry companies provide complete information about drainage grate structural capacity but provide nothing about their hydraulic capacity. This fact can be seen because at the moment does not exist any official regulation at national or international level in this field. It's obvious that, nowadays, there is a great gap in this field at the legislative level owing to the complexity of this field and the modernity of the urban hydrology as science [1]. In essence, we shows the relevance to know the inlet hydraulic interception capacity because surface drainage requires a satisfactory knowledge on storm frequency, gutter flow and above all inlet capacity. In addition, we development an important achievement is the invention and development of techniques for measurement of field velocities in hydraulics engineering applications. Hence knowledge the technological advances in digital cameras with high resolution and high speed found in the environmental, and the advances in image processing techniques, therefore now is a tremendous potential to obtain of behavior of the water surface flow [2].

    Often, during daily experiences, hearing peers' actions can activate motor regions of the CNS. This activation is termed auditory-motor resonance (AMR) and is thought to represent an internal simulation of one's motor memories. Currently, AMR is demonstrated at the neuronal level in the Macaque and songbird, in conjunction with evidence on a systems level in humans. Here, we review evidence of AMR development from a motor control perspective. In the context of internal modelling, we consider data that demonstrates sensory-guided motor learning and action maintenance, particularly the notion of sensory comparison seen during songbird vocalisation. We suggest that these comparisons generate accurate sensory-to-motor inverse mappings. Furthermore, given reports of mapping decay after songbird learning, we highlight the proposal that the maintenance of these sensorimotor maps potentially explains why frontoparietal regions are activated upon hearing known sounds (i.e., AMR). In addition, we also recommend that activation of these types of internal models outside of action execution may provide an ecological advantage when encountering known stimuli in ambiguous conditions.

    2017-05-01

    Internal medicine residents are frequently called upon to provide palliative care to hospitalized patients, but report feeling unprepared to do so effectively. Curricular development to enhance residents' palliative care skills and competencies requires an understanding of current beliefs, attitudes and learning priorities. We conducted a qualitative study consisting of semi-structured interviews with ten internal medicine residents to explore their understanding of and experiences with palliative care. All of the residents interviewed had a sound theoretical understanding of palliative care, but faced many challenges in being able to provide care in practice. The challenges described by residents were system-related, patient-related and provider-related. They identified several priority areas for further learning, and discussed ways in which their current education in palliative care could be enhanced. Our findings provide important insights to guide curricular development for internal medicine trainees. The top five learning priorities in palliative care that residents identified in our study were: 1) knowing how and when to initiate a palliative approach, 2) improving communication skills, 3) improving symptom management skills, 4) identifying available resources, and 5) understanding the importance of palliative care. Residents felt that their education in palliative care could be improved by having a mandatory rotation in palliative care, more frequent didactic teaching sessions, more case-based teaching from palliative care providers, opportunities to be directly observed, and increased support from palliative care providers after-hours.

    The emerging global-health paradigm requires medical teaching to be continuously redefined and updated; to this end, transnational approaches should be encouraged and medical training harmonized. Infectious diseases (ID) teaching in the current context of emerging infections, fast-increasing bacterial resistance and large-scale human migration, was chosen to develop a common international course. We report the successful implementation of a joint European undergraduate course aiming to (i) develop a common ID core curriculum among European medical schools; (ii) promote mobility among teachers and students (iii) promote international cooperation among European teachers. The course was built around teachers' mobility. It was delivered in English by a team of European medical educators from Paris Descartes University, Università Cattolica del Sacro Cuore in Rome and the University of Edinburgh to groups of 25-30 undergraduate medical students at each university. Partner Institutions officially recognized the course as substitutive of or additive to the regular curriculum. The course has been running for 3 years and received excellent satisfaction scores by students and staff as regards to scientific content, pedagogy and international exchanges. This cooperative approach demonstrates the feasibility of a harmonized European undergraduate medical education, having ID as a test experiment for future developments.

    Since the mid-1990s, a large number of foreign women have migrated from developing countries to South Korea by means of international marriages. These nulliparous foreign women may experience more difficulties in pregnancy and childbirth than native Koreans. This study aimed to describe the meaning of the first childbirth experiences of international marriage migrant women marrying Korean men in South Korea. This is a descriptive phenomenological study that included 10 participants using the purposive and snowball sampling in one multicultural support center in Seoul, South Korea. Colaizzi's data analysis method was used to inductively determine themes and formulate meanings. The meanings of first childbirth were categorized into four themes-'coming to a crisis,' 'depending on others,' 'searching for solutions,' and 'strengthening family unity.' Inadequate antenatal care is associated with obstacles such as language barriers, social isolation, lack of knowledge, different midwifery practice and dependent lifestyle. Meanwhile, their children were a source of energy for the women to fulfill their emotional needs and improve family relationships. Childbirth is a life-changing event for these women, in which they face challenges as well as opportunities to develop new coping skills and a new role identity in their family. It is important for healthcare providers and policy makers to identify obstacles and unmet needs to improve maternity care in light of the distinctive challenges of immigrant living in multicultural families.

    One of the problems one is faced with when uranium mines are closed is the decontamination of acid mine drainage (AMD) from tailings and flooding of the underground mines. The high concentrations of sulfates and metals in mining water make it impossible to dispose of the water into rivers without having to decontaminate it first. A bioremediation process is proposed in which sulfate-reducing bacteria are used to remove metals, neutralize the water and reduce the sulfate concentrations. Methylotrophic sulfate-reducing strains have been isolated which can be used in such a process. Lab scale experiments with different reactor types were carried out in order to find the optimum design for this bioremediation process. Comparisons were made between methanol and other electron donors with regards to their suitability as substrate for this process. Methanol was found to be most suited. Laboratory data suggest that immobilizing the bacteria on pumice particles increases the sulfate-reduction rate (SRR) up to three fold to 18 mg/l.h, compared to the rates of free flowing cells of between 3.7 and 6.8 mg/l.h. Preliminary experiments on a larger scale (15 l) using acid mine drainage pH 2.5 show SRR of 0.71 mg/l.h. In biosorption experiments up to 140 mg of aluminium per g biomass was removed from the water. One strain was found to reduce uranium VI, thus changing it from the soluble to the insoluble form. The application of the proposed process with regards to bioremediation of AMD are discussed. (orig.)

    To analyse the literature regarding the context and experiences of internationally qualified registered nurses, particularly Filipino and Indian nurses, who have transitioned to New Zealand. Internationally qualified nurses are a significant proportion of the nursing workforce in many developed countries including New Zealand. This is increasingly important as populations age, escalating demand for nurses. Understanding the internationally qualified nurse experience is required as this could influence migration in a competitive labour market. Examination of peer-reviewed research, policy and discussion documents, and technical reports. A systematic literature search sought articles published between 2001 and 2014 using Google Scholar, CINAHL, and Medline. Articles were critically appraised for relevance, transferability, and methodological rigour. Fifty-one articles met inclusion criteria and demonstrate internationally qualified nurses face significant challenges transitioning into New Zealand. The internationally qualified nurse experience of transitioning into a new country is little researched and requires further investigation.

    The current study explores the potential mediating role of internalized racism in the relationship between racist experiences and anxiety symptomology in a Black American sample. One hundred and 73 Black American participants, between 18 and 62 years of age, completed a questionnaire packet containing measures of anxious arousal and stress symptoms, internalized racism, and experiences of racist events. Results indicated that internalized racism mediated the relationship between past-year frequency of racist events and anxious arousal as well as past-year frequency of racist events and stress symptoms. Internalized racism may be 1 mechanism that underlies the relationship between racism and anxious symptomology for Black Americans. These preliminary findings suggest that internalized racism may be an avenue through which clinicians can target the anxiety elicited by racist experiences. The clinical implications of these findings and future research directions are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    The Texas A&M REU in Costa Rica provides students with an opportunity to participate in research on the ecohydrology of a tropical pre-montane forest. The international and field components of this program require both that students to work in research clusters of several faculty and students, and that each of the clusters contribute to a primary research question of closing the water budget for a small watershed. Specifically, students and faculty participate in precipitation (P), evapotranspiration (E), hydrology (Q) or subsurface storage (DS) research clusters. It is argued that having the students at a central research station location and focusing their research on a common research problem is an important aspect of an international REU program to avoid a feeling of isolation and to ensure that the students remain safe in their research and during their free time. However, this shared experience and research question can highlight differences among the faculty mentors and make the students evaluate their individual experience more critically. To better understand the relationship between the REU student and their faculty mentor(s), we have been conducting pre- and post-surveys, interviews, and focus groups to understand their experience in the REU and the manner in which the faculty mentor can affect that experience and the desire to continue in research. Results of the pre-trip survey suggest that the undergraduate students are most concerned about their projects and show little no concern about the faculty mentor with whom they will be completing their research. Post-trip results from 2011 and 2012 suggest that mentors had a much greater impact on the experience than expected. Many students said that their future research/graduate school plans were significantly affected by their REU mentor relationship. One student said that by working closely with mentors, "you know that what you are doing and learning is pertinent because you are learning it from actual

    Detailed discussions were held with members of the Gallium Experiment (GALLEX) international solar neutrino research collaboration concerning negotiations to provide $1.4 million in services to enrich (50)Cr for a (51)Cr neutrino source. The source will be used to calibrate the 20-ton gallium solar neutrino detector currently in place in the Gran Sasso Laboratory in Italy. Funding approval for the enrichment services is expected from the European Common Market by October 19, 1990. The discussions focused on the technical aspects of the enrichment, the health and safety requirements for handling the process gas, cost projections, schedule, the Work-for-Others contract, and the method of payment. Discussions were also held with members of the Nuclear Physics Dept. at the University of Milan concerning the availability of isotopes enriched by the Calutron at the Oak Ridge National Laboratory. Very high purity material is needed to grow crystals for use in double beta decay detectors. Finally, working sessions were held to draft a coauthored paper on the results of using the gas centrifuge to remove trace quantities of (85)Kr from natural xenon.

  16. International Handbook of Evaluated Criticality Safety Benchmark Experiments - ICSBEP (DVD), Version 2013

    International Nuclear Information System (INIS)

    2013-01-01

    The Criticality Safety Benchmark Evaluation Project (CSBEP) was initiated in October of 1992 by the United States Department of Energy. The project quickly became an international effort as scientists from other interested countries became involved. The International Criticality Safety Benchmark Evaluation Project (ICSBEP) became an official activity of the Organisation for Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) in 1995. This handbook contains criticality safety benchmark specifications that have been derived from experiments performed at various nuclear critical experiment facilities around the world. The benchmark specifications are intended for use by criticality safety engineers to validate calculational techniques used to establish minimum subcritical margins for operations with fissile material and to determine criticality alarm requirement and placement. Many of the specifications are also useful for nuclear data testing. Example calculations are presented; however, these calculations do not constitute a validation of the codes or cross section data. The evaluated criticality safety benchmark data are given in nine volumes. These volumes span nearly 66,000 pages and contain 558 evaluations with benchmark specifications for 4,798 critical, near critical or subcritical configurations, 24 criticality alarm placement/shielding configurations with multiple dose points for each and 200 configurations that have been categorised as fundamental physics measurements that are relevant to criticality safety applications. New to the Handbook are benchmark specifications for Critical, Bare, HEU(93.2)- Metal Sphere experiments referred to as ORSphere that were performed by a team of experimenters at Oak Ridge National Laboratory in the early 1970's.

  17. Nocturnal drainage wind characteristics in two converging air sheds

    International Nuclear Information System (INIS)

    Gedayloo, T.; Clements, W.E.; Barr, S.; Archuleta, J.A.

    1980-01-01

    During the short experimental period in the Grants Basin of Northeastern New Mexico a survey was conducted on the complex meteorology of this area. Emphasis was placed on the nocturnal drainage flow because of the potential hazards to the populated areas of Milan and Grants from the effluents of the uranium mining and milling operation in this area. This investigation has shown that the nocturnal drainage flow patterns agree with the winds predicted on the basis of the complex terrain of the area. Because of the surface cooling at night (over 25 0 C during summer and about 20 0 C during winter), air from elevated surrounding areas flows to the low lying regions consequently setting up a nocturnal drainage flow. This regime exists over 60% of the time during summer months and over 65% of the time during winter months with a depth generally less than 200 m. In the San Mateo air shed the drainage flow is east northeast, and in the Ambrosia Lake air shed it is from northwest. The confluence of these two air flows contributes mainly to the drainage flow through the channel formed by La Ja Mesa and Mesa Montanosa. The analysis of data collected by the recording Flats Station confirms the prediction that although the area south of the channel region broadens considerably causing a reduction in flow speed, contributions from the southside of La Jara Mesa and Mesa Montanosa partly compensate for this reduction. The position of this recording station is 15 to 20 km from the populated towns of Milan and Grants. A drainage flow speed of approximately 2.2 m s -1 and the duration of over 11 hours as recorded by this station indicates that air from the San Mateo and Ambrosia Lake regions may be transported southwards to these population centers during a nocturnal period. In order to test this prediction, a series of multi-atmospheric tracer experiments were conducted in the Grants Basin

    This report is an investigation of the beam parameter evolution in the experiments with internal target. In calculations of the proton and deuteron beams we concentrated on cluster, atomic beam, storage cell and pellet targets at ANKE experiment mainly. In these calculations electron and stochastic cooling, intrabeam scattering, scattering on the target and residual gas atoms are taken into account. Beam parameter evolution is investigated in the long-term time scale, up to one hour, at different beam energies in the range from 1.0 to 2.7 GeV for proton beam and from 1 to 2.11 GeV for deuteron beam. The results of numerical simulations of the proton and deuteron beam parameters at different energies obtained using new version of BETACOOL program (elaborated at the first stage of this work [1]) are presented. Optimum parameters of the electron cooling system are estimated. The COSY experiment requirements can be satisfied even when electron cooling time is rather long. That allows to apply an electron cooling ...

    A ground-based experimental facility to perform flow boiling and condensation experiments is built in support of the development of the long duration Flow Boiling and Condensation Experiment (FBCE) destined for operation on board of the International Space Station (ISS) Fluid Integrated Rack (FIR). We performed tests with the condensation test module oriented horizontally and vertically. Using FC-72 as the test fluid and water as the cooling fluid, we evaluated the operational characteristics of the condensation module and generated ground based data encompassing the range of parameters of interest to the condensation experiment to be performed on the ISS. During this testing, we also evaluated the pressure drop profile across different components of the fluid subsystem, heater performance, on-orbit degassing subsystem, and the heat loss from different components. In this presentation, we discuss representative results of performance testing of the FBCE flow loop. These results will be used in the refinement of the flight system design and build-up of the FBCE which is scheduled for flight in 2019.

    Materials and devices used on the exterior of spacecraft in low Earth orbit (LEO) are subjected to environmental threats that can cause degradation in material properties, possibly threatening spacecraft mission success. These threats include: atomic oxygen (AO), ultraviolet and x-ray radiation, charged particle radiation, temperature extremes and thermal cycling, micrometeoroid and debris impacts, and contamination. Space environmental threats vary greatly based on spacecraft materials, thicknesses and stress levels, and the mission environment and duration. For more than a decade the Materials International Space Station Experiment (MISSE) has enabled the study of the long duration environmental durability of spacecraft materials in the LEO environment. The overall objective of MISSE is to test the stability and durability of materials and devices in the space environment in order to gain valuable knowledge on the performance of materials in space, as well as to enable lifetime predictions of new materials that may be used in future space flight. MISSE is a series of materials flight experiments, which are attached to the exterior of the International Space Station (ISS). Individual experiments were loaded onto suitcase-like trays, called Passive Experiment Containers (PECs). The PECs were transported to the ISS in the Space Shuttle cargo bay and attached to, and removed from, the ISS during extravehicular activities (EVAs). The PECs were retrieved after one or more years of space exposure and returned to Earth enabling post-flight experiment evaluation. MISSE is a multi-organization project with participants from the National Aeronautics and Space Administration (NASA), the Department of Defense (DoD), industry and academia. MISSE has provided a platform for environmental durability studies for thousands of samples and numerous devices, and it has produced many tangible impacts. Ten PECs (and one smaller tray) have been flown, representing MISSE 1 through MISSE

    This paper describes a space solar cell experiment currently being built by the Naval Research Laboratory (NRL) in collaboration with NASA Glenn Research Center (GRC), and the US Naval Academy (USNA). The experiment has been named the Forward Technology Solar Cell Experiment (FTSCE), and the purpose is to rapidly put current and future generation space solar cells on orbit and provide validation data for these technologies. The FTSCE is being fielded in response to recent on-orbit and ground test anomalies associated with space solar arrays that have raised concern over the survivability of new solar technologies in the space environment and the validity of present ground test protocols. The FTSCE is being built as part of the Fifth Materials on the International Space Station (MISSE) Experiment (MISSE-5), which is a NASA program to characterize the performance of new prospective spacecraft materials when subjected to the synergistic effects of the space environment. Telemetry, command, control, and communication (TNC) for the FTSCE will be achieved through the Amateur Satellite Service using the PCSat2 system, which is an Amateur Radio system designed and built by the USNA. In addition to providing an off-the-shelf solution for FTSCE TNC, PCSat2 will provide a communications node for the Amateur Radio satellite system. The FTSCE and PCSat2 will be housed within the passive experiment container (PEC), which is an approximately 2ft x2ft x 4in metal container built by NASA Langley Research Center (NASA LaRC) as part of the MISSE-5 program. NASA LaRC has also supplied a thin film materials experiment that will fly on the exterior of the thermal blanket covering the PCSat2. The PEC is planned to be transported to the ISS on a Shuttle flight. The PEC will be mounted on the exterior of the ISS by an astronaut during an extravehicular activity (EVA). After nominally one year, the PEC will be retrieved and returned to Earth. At the time of writing this paper, the

    Thomas, David S. G.; Shaw, Paul A.

    The development of the Zambezi drainage system is discussed within the framework of the post-Gondwana tectonic evolution of southern Africa. An internal drainage system, including teh proto-Upper Zambezi, has been progressively captured during the late Cainozoic by a more agressive coastwise system. Supporting geomorphic evidence is presented from the eastern Kalahari rim. Drainage alignments and gradients, and terrace sequences are discussed. Lacustrine features found on the present watershed between the Middle Zambezi and internal systems are described and explained as remnants of the former proto-Upper Zambezi tributary system. Their interaction with linear dune activity is also examined. Despite the problems of dating the drainage changes described, it is concluded that their elucidation is important in understanding sedimentation and landform development in the eastern part of the Kalahari basin.

    The success of France's nuclear power program can be attributed to two main factor. Firstly, the necessity for France to increase its energy independence. Nuclear energy was the only viable choice, but French industry had to master all the phases of such a program. Secondly, a will to pursue the objectives set, which has remained steadfast for over 20 years. Today, two-thirds of French electricity comes from unclear power, and the French program is continuing its regular progression. Several times already, in particular in this pacific basin region, French industry has cooperated in nuclear power projects abroad. It is convinced that even greater international cooperation can only be beneficial for all, and is ready , for its part, to bring to bear on this effort all of its experience and resources. (author)

    To summarize international experiences in promoting use of generics and to extract essence for China's reference. This is a commentary of two systematic reviews about policies to promote use of generics and its implications to China. Price, reimbursement, and generic substitution policies in European countries, and approaches in low and middle income countries in promoting market competition, appropriate intellectual property right protection strategy, and necessary demand side incentives, are all meaningful for China to contain soaring pharmaceutical expenditures, and to maintain the achievements and outcomes of the national health system reform. Effective promotion of generics use must be practice based on the real situation. Tailor-made and comprehensive measures are needed to address both demand and supply sides barriers before achieving tangible cost containment effect without unexpected side effects. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

  6. Feasibility analysis of large length-scale thermocapillary flow experiment for the International Space Station

    Science.gov (United States)

    Alberts, Samantha J.

    The investigation of microgravity fluid dynamics emerged out of necessity with the advent of space exploration. In particular, capillary research took a leap forward in the 1960s with regards to liquid settling and interfacial dynamics. Due to inherent temperature variations in large spacecraft liquid systems, such as fuel tanks, forces develop on gas-liquid interfaces which induce thermocapillary flows. To date, thermocapillary flows have been studied in small, idealized research geometries usually under terrestrial conditions. The 1 to 3m lengths in current and future large tanks and hardware are designed based on hardware rather than research, which leaves spaceflight systems designers without the technological tools to effectively create safe and efficient designs. This thesis focused on the design and feasibility of a large length-scale thermocapillary flow experiment, which utilizes temperature variations to drive a flow. The design of a helical channel geometry ranging from 1 to 2.5m in length permits a large length-scale thermocapillary flow experiment to fit in a seemingly small International Space Station (ISS) facility such as the Fluids Integrated Rack (FIR). An initial investigation determined the proposed experiment produced measurable data while adhering to the FIR facility limitations. The computational portion of this thesis focused on the investigation of functional geometries of fuel tanks and depots using Surface Evolver. This work outlines the design of a large length-scale thermocapillary flow experiment for the ISS FIR. The results from this work improve the understanding thermocapillary flows and thus improve technological tools for predicting heat and mass transfer in large length-scale thermocapillary flows. Without the tools to understand the thermocapillary flows in these systems, engineers are forced to design larger, heavier vehicles to assure safety and mission success.

    2007-01-01

    Since the beginning of the 1990's, the OECD Nuclear Energy Agency (NEA) has offered its member countries a forum for improving efficiency and effectiveness in nuclear emergency management, focusing in particular on the international aspects of emergency preparedness and response. A central approach to this has been the preparation and conduct of the International Nuclear Emergency Exercise (INEX) series. The INEX 3 consequence management exercises were developed by the NEA Working Party on Nuclear Emergency Matters in response to its members desire to better prepare for the longer-term response following a nuclear or radiological emergency. The INEX 3 exercise series was developed in 2002-2004, and conducted throughout 2005 and early 2006 by 15 participating countries. The INEX 3 evaluation workshop held in Paris (France) in May 2006 was convened with the objective of allowing participants to share their national experiences with INEX 3, compare approaches, analyse the implications on decision making and identify key needs in longer-term consequence management. In addition to providing a valuable discussion forum for participants, the workshop concluded by establishing a set of identified needs in longer-term consequence management to which the participants felt that the NEA and international community could usefully contribute. These included the four main areas addressed by the exercise agriculture and food countermeasures, decisions on countermeasures such as travel, trade or tourism, recovery management and public information as well as stakeholder involvement and liability/compensation issues. This report summarises the development of the INEX 3 exercise, the major evaluation outcomes of the national exercises, and the key policy-level outcomes, recommendations and follow-up activities arising from the exercise and workshop.

    We compared English language and cognitive skills between internationally adopted children (IA; mean age at adoption=2.24, SD=1.8) and their non-adopted peers from the US reared in biological families (BF) at two time points. We also examined the relationships between outcome measures and age at initial institutionalization, length of institutionalization, and age at adoption. On measures of general language, early literacy, and non-verbal IQ, the IA group performed significantly below their age-peers reared in biological families at both time points, but the group differences disappeared on receptive vocabulary and kindergarten concept knowledge at the second time point. Furthermore, the majority of children reached normative age expectations between 1 and 2 years post-adoption on all standardized measures. Although the age at adoption, age of institutionalization, length of institutionalization, and time in the adoptive family all demonstrated significant correlations with one or more outcome measures, the negative relationship between length of institutionalization and child outcomes remained most robust after controlling for the other variables. Results point to much flexibility and resilience in children's capacity for language acquisition as well as the potential primacy of length of institutionalization in explaining individual variation in IA children's outcomes. (1) Readers will be able to understand the importance of pre-adoption environment on language and early literacy development in internationally adopted children. (2) Readers will be able to compare the strength of the association between the length of institutionalization and language outcomes with the strength of the association between the latter and the age at adoption. (3) Readers will be able to understand that internationally adopted children are able to reach age expectations on expressive and receptive language measures despite adverse early experiences and a replacement of their first

    2008-01-01

    The greater demand for electricity and the available capacity within safety margins in some operating NPPs are prompting nuclear utilities to request license modification to enable operation at a higher power level, beyond their original license provisions. Such plant modifications require an in-depth safety analysis to evaluate the possible safety impact. The analysis must consider the thermo hydraulic, radiological and structural aspects, and the plant behavior, while taking into account the capability of the structures, systems and components, and the reactor protection and safeguard systems set points. The purpose of this paper is to introduce international experiences and approaches for implementation of power uprates related to the reactor thermal power of nuclear power plants. The paper is intended to give the reader a general overview of the major processes, work products, issues, challenges, events, and experiences in the power uprates program. The process of increasing the licensed power level of a nuclear power plants is called a power uprate. One way of increasing the thermal output from a reactor is to increase the amount of fissile material in use. It is also possible to increase the core power by increasing the performance of the high power bundles. Safety margins can be maintained by either using fuels with a higher performance, or through the use of improved methods of analysis to demonstrate that the required margins are retained even at the higher power levels. The paper will review all types of power uprates, from small to large, and across various reactor types, including light and heavy water, pressurized, and boiling water reactors. Generally, however, the content of the report focuses on power uprates of the stretch and extended type. The International Atomic Energy Agency (IAEA) is developing a technical guideline on power uprates and side effects of power uprates in nuclear power plants

    2013-01-01

    In 2011, the Accreditation Council for Graduate Medical Education Surgery Residency Review Committee first provided guidelines for elective international general surgery rotations. The Vanderbilt general surgery residency program received Surgery Residency Review Committee approval for a fourth-year elective in Kenya beginning in the 2011-2012 academic year. Because this rotation would break ground culturally and geographically, and as an educational partnership, a briefing and debriefing process was developed for this ground-breaking year. Our objectives were to prepare residents to maximize the experience without competing for cases with local trainees or overburdening the host institution and to perform continuous quality assessment and improvement as each resident returned back. Briefing included health protection strategies, a procedures manual containing step-by-step preparation activities, and cultural-sensitivity training. Institutional Review Board exemption approval was obtained to administer a questionnaire created for returning residents concerning educational value, relations with local trainees, physical environment, and personal perceptions that would provide the scaffold for the debriefing conference. The questionnaire coupled with the debriefing discussion for the first 9 participants revealed overall satisfaction with the rotation and the briefing process, good health, and no duty hours or days-off issues. Other findings include the following: (1) emotional effect of observing African families weigh cost in medical decision making; (2) satisfactory access to educational resources; (3) significant exposure to specialties such as urology and radiology; and (4) toleration of 4 weeks as a single and expressed need for leisure activity materials such as books, DVDs, or games. The responses triggered adjustments in the briefing sessions and travel preparation. The host institution invited the residents to return for the 2012-2013 year as well as 2013

    1983-01-01

    The International Commission on Radiological Protection has issued radiation protection recommendations since 1928. The latest set of basic recommendations was adopted by the Commission on 17 January 1977, and subsequently published as ICRP Publication 26. This document has met with a wider interest than any of the previous ICRP recommendations. It has been considered to mark a radical change in the protection policy advocated by ICRP. It is not often appreciated that recommendations which are believed to be 'new' in ICRP Publication 26 had already been made in ICRP Publication 9 more than ten years earlier. In any event, ICRP Publication 26 has had a substantial impact on regulatory work in countries all over the world. It forms the basis for the Basic Safety Standards of the international organizations IAEA, ILO, OECD/NEA and WHO. The paper refers to the experience gained in using the new ICRP recommendations over the five years that have passed since ICRP Publication 26 was adopted and discusses some of the problems that have arisen in the practical application of the new recommendations in various countries.

    Traditionally, spent fuel assemblies (SFA) have been transported across the Russian Federation by rail in special railcars. New conditions required SFA shipments by other conveyance, i.e. road, sea and even air transport. The air shipment of the VVR-S research reactor SNF in TUK-19 casks from Magurele, Romania in June 2009 was the first experience after new Russian and international regulations for the safe transport of radioactive material came into effect. The preparatory stage of the shipment focused on the issues associated with radiation and nuclear safety both during the loading and transport operations. The project covered development of a technology and equipment for SFA loading into TUK-19 casks and that for the air shipment. The SFAs were loaded into the TUK-19 casks with a specially designed transfer cask, and the SFA-containing packages were transported in specialized freight 20-foot ISO-containers. The safety of the loading and transport operations was ensured both by reliable engineering solutions, and selected conveyances and routes. The paper shows that the loading and the air shipment of the Romanian SFAs in TUK-19 casks does not contradict Romanian, Russian and international regulations for the safe transport of radioactive material. The outcomes of the SNF shipment from Romania confirmed correctness of the solutions and demonstrated high environmental safety. (author)

    The increasing flow of Syrian refugees to Turkey, coupled with their extended stay, highlights the need for culturally competent health care, which includes nursing interventions. The purpose of this study was to describe the experiences of nurses who provide care for Syrian refugees in internal medicine clinics in a hospital located in Turkey. This descriptive study was based on qualitative content analysis using an inductive approach and involved discovery and description of the data. The study sample consisted of 10 nurses who work at the internal medicine clinic of a State Hospital in Turkey. Data were collected using semistructured interviews. Three themes with related subthemes were derived from the data. Nurses who participated in the study experienced: (a) Nurses found communicating with Syrian refugees and their families difficult in the clinic. (b) Nurses observed and experienced differences and similarities in caring for Turkish and Syrian patients. (c) Nurses expressed and displayed compassion toward Syrian refugees during the caring process. In order for nurses to provide the best care for Syrian refugee patients, it is important to identify cultural caring behaviors observed by nurses in the promotion of culturally congruent nursing and health care.

  17. Manual for IRS Coding. Joint IAEA/NEA International Reporting System for Operating Experience

    2011-01-01

    The International Reporting System for Operating Experience (IRS) is jointly operated by the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency of the Organisation for Economic Co-operation and Development (OECD/NEA). In early 2010, the IAEA and OECD/NEA jointly issued the IRS Guidelines, which described the reporting system and process and gave users the necessary elements to enable them to produce IRS reports to a high standard of quality while retaining the effectiveness of the system expected by all Member States operating nuclear power plants. The purpose of the present Manual for IRS Coding is to provide supplementary guidance specifically on the coding element of IRS reports to ensure uniform coding of events that are reported through IRS. This Coding Manual does not supersede the IRS Guidelines, but rather, supports users and preparers in achieving a consistent and high level of quality in their IRS reports. Consistency and high quality in the IRS reports allow stakeholders to search and retrieve specific event information with ease. In addition, well-structured reports also enhance the efficient management of the IRS database. This Coding Manual will give specific guidance on the application of each section of the IRS codes, with examples where necessary, of when and how these codes are to be applied. As this reporting system is owned by the Member States, this manual has been developed and approved by the IRS National Coordinators with the assistance of the IAEA and NEA secretariats

  18. Transformation of internal solitary waves at the "deep" and "shallow" shelf: satellite observations and laboratory experiment

    2013-10-01

    Full Text Available An interaction of internal solitary waves with the shelf edge in the time periods related to the presence of a pronounced seasonal pycnocline in the Red Sea and in the Alboran Sea is analysed via satellite photos and SAR images. Laboratory data on transformation of a solitary wave of depression while passing along the transverse bottom step were obtained in a tank with a two-layer stratified fluid. The certain difference between two characteristic types of hydrophysical phenomena was revealed both in the field observations and in experiments. The hydrological conditions for these two processes were named the "deep" and the "shallow" shelf respectively. The first one provides the generation of the secondary periodic short internal waves – "runaway" edge waves – due to change in the polarity of a part of a soliton approaching the shelf normally. Another one causes a periodic shear flow in the upper quasi-homogeneous water layer with the period of incident solitary wave. The strength of the revealed mechanisms depends on the thickness of the water layer between the pycnocline and the shelf bottom as well as on the amplitude of the incident solitary wave.

    2010-09-01

    This study investigated links between internal working models of attachment and the quality of adult love relationships in a high risk sample of women (n = 34), all of whom reported negative parenting in childhood. Half of the sample was identified as having a history of satisfying adult love relationships, while the remainder had experienced ongoing adult relationship problems. Measures of internal working models of attachment were made using the Adult Attachment Interview (AAI). A strong association was found between attachment classifications and the quality of adult love relationships. In addition, women with satisfying love relationships demonstrated significantly higher coherence of mind ratings than those with poor relationship histories. Insecure working models of attachment were associated with problems in adult love relationships. Although secure/autonomous attachment status was linked to optimal adult relationship outcomes, some women with a history of satisfying love relationships had insecure working models of attachment. These results suggest that the ways that adults process early experiences may influence later psychosocial functioning.

    Intracranial internal carotid artery aneurysms are an extremely rare cause of spontaneous epistaxis, with a few documented cases. The management of such cases is challenging due to the relative anatomical inaccessibility of the bleeding point. The aim of the present study was to acquaint the readers with this rare type of aneurysm presenting with epistaxis and to report our experience of treating cases of severe epistaxis due to internal carotid artery (ICA) aneurysms. Data of 4 patients with İCA aneurysms presenting with epistaxis from June 2011 to July 2013 was retrospectively reviewed. The age of patients ranged from 16 to 62 years. Duration of epistaxis ranged from 3 months to 3 years. Two patients had severe epistaxis following transnasal biopsy. Two patients had a history of trauma. Two patients developed hemodynamically instability. All the patients were managed with trapping of the aneurysm. Complete exclusion of aneurysm from circulation was achieved in all the patients. ICA aneurysms can rarely present as life-endangering epistaxis. In patients presenting with a history of craniocerebral trauma, traumatic pseudoaneurysm must be considered as a differential diagnosis. Trapping of the aneurysm is a good option if there is good cross circulation.

    Occupational health professionals need to know more about the health, worklife, and family life of international business travelers (IBTs). This descriptive correlational study, in two parts, examines the physiological and psychosocial experiences associated with business travel for a sample of 140 employees from western Canada's oil and gas industry. Results for Part One show that 76% of IBTs report travel related health problems, 74% have jet lag, 45% have travelers' diarrhea and gastrointestinal complaints, 12% to 16% have climate adaptation problems, and 2% report accidents and minor injuries. High risk behaviors include not carrying a first aid travel kit (54%); drinking more alcohol than ordinarily (21%); and neglecting food, water, and antimalarial precautions (6% to 14%). Other risk factors include age, length of stay, destination, pre-travel medical examinations, pre-travel advice, and eating and accommodation facilities. Findings show that IBTs are at risk for travel related physiological health problems. Implications for practitioners call for increased occupational health expertise in pre-travel preparation, follow up post-travel and regular health surveillance for employees who travel on international business.

    As the Space Shuttle continues flight, construction and assembly of the International Space Station (ISS) carries on as the United States and our International Partners resume the building, and continue to carry on the daily operations, of this impressive and historical Earth-orbiting research facility. In his January 14, 2004, speech announcing a new vision for America s space program, President Bush ratified the United States commitment to completing construction of the ISS by 2010. Since the launch and joining of the first two elements in 1998, the ISS and the partnership have experienced and overcome many challenges to assembly and operations, along with accomplishing many impressive achievements and historical firsts. These experiences and achievements over time have shaped our strategy, planning, and expectations. The continual operation and assembly of ISS leads to new knowledge about the design, development and operation of systems and hardware that will be utilized in the development of new deep-space vehicles needed to fulfill the Vision for Exploration and to generate the data and information that will enable our programs to return to the Moon and continue on to Mars. This paper will provide an overview of the complexity of the ISS Program, including a historical review of the major assembly events and operational milestones of the program, along with the upcoming assembly plans and scheduled missions of the space shuttle flights and ISS Assembly sequence.

    Full Text Available This study is focused on exploration of experience of cultural transition that has lived a group of international students (European and not European host at an Italian University during particular experiential segment marking the transition from their culture of belonging to the new social and cultural context. From an epistemological point of view that aligns with the phenomenological tradition with individual and group interviews, it was monitored with a longitudinal methodology as the representation of the transit cross-cultural adaptation to the context it emerged from the interviews are associated through the dominant narrative themes. The results show how in the early stage of contact with the new culture, the group of students, both European and not, have felt a sense of disorientation associated with the loss of its cultural matrix. Over the next step of analysis is rather more clearly the difference between the group of European students, whose performances evoke an adjustment process easier and less based on feelings of ambivalence and close relationships that characterize the group of non-European students.Keywords: Cross-cultural transition; International students: Phenomenology

    Endoscopic retrograde cholangiography (ERCP) is currently standard treatment for biliary drainage. Endoscopic ultrasound guided rendezvous (EUS-RV) is a novel method to overcome an unsuccessful biliary drainage procedure. Under endoscopic ultrasound guidance a guidewire is passed via a needle from the stomach or duodenum to the common bile duct and from there on to the duodenum enabling ERCP. With a relatively high rate of success EUS-RV should be considered as an alternative to biliary drainage and surgical intervention.

    From March 1987 to July 1989, six patients (five adults and one child) with lung abscess (size, 5-13 cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr cartheter was inserted for drainage. Five of 6 had a dynamatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days(average, 15.5 days) in successful cases. One case of the failure in drainage was due tio persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provide anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is safe and effective method for treating patient with lung abscess.

    Glaucoma is a frequent reason of loss vision. It is usually caused by increased intraocular pressure leading to damage of optic nerve head. This work deals with the development of fibrous structure suitable for glaucoma drainage implants (GDI). Commercially produced metallic glaucoma implants are very effective in lowering intraocular pressure. However, these implants may cause adverse events such as damage to adjacent tissue, fibrosis, hypotony or many others [1]. The aim of this study is to reduce undesirable properties of currently produced drains and improve their properties by creating of the composite fibrous drain for achieve a normal intraocular pressure. Two types of electrospinning technologies were used for the production of very small tubular implants. First type was focused for production of outer part of tubular drain and the second type of electrospinning method made the inner part of shape follows the connections of both parts. Complete implant had a special properties suitable for drainage of fluid. Morphological parameters, liquid transport tests and in-vitro cell adhesion tests were detected.

    plants dismantled to date in the US have repackaged the less activated waste back into the reactor vessel and shipped the entire assembly to the disposal site. Decisions like these can be driven by many factors such as disposal costs, transportation logistics, licensing fees, etc., but will have a significant impact on the segmentation and packaging plan so must be considered early in the planning phase. All segmentation tools are remotely controlled since the mechanical segmentation projects that Westinghouse has executed, so far, have been performed under water due to the high radiation levels. ALARA and personal safety is the number one priority during the site work. The complexity of the work requires well designed and reliable tools. Westinghouse has optimized the technologies from its experiences accumulated over the years. Its main focus has always been to improve tool handling and cutting speed, water cleanliness, fail-safe and safety aspects. Different band saws, disc saws, tube cutters and shearing tools have been developed to cut the reactor internals. All of those equipments are hydraulically driven which is very suitable for submerged applications. The purpose of this paper will be to provide an overview of the Westinghouse mechanical segmentation process, based on actual experience from the work that has been completed to date. (authors)

    Intracontinental endorheic basins are key elements of source-to-sink systems as they preserve sediments eroded from the surrounding catchments. Drainage reorganization in such a basin in response to changing boundary conditions has strong implications on the sediment routing system and on landscape evolution. The Ebro and Duero basins represent two foreland basins, which developed in response to the growth of surrounding compressional orogens, the Pyrenees and the Cantabrian mountains to the north, the Iberian Ranges to the south, and the Catalan Coastal Range to the east. They were once connected as endorheic basins in the early Oligocene. By the end of the Miocene, new post-orogenic conditions led to the current setting in which the Ebro and Duero basins are flowing in opposite directions, towards the Mediterranean Sea and the Atlantic Ocean. Although these two hydrographic basins recorded a similar history, they are characterized by very different morphologic features. The Ebro basin is highly excavated, whereas relicts of the endorheic stage are very well preserved in the Duero basin. The contrasting morphological preservation of the endorheic stage represents an ideal natural laboratory to study the drivers (internal and/or external) of post-orogenic drainage divide mobility, drainage network, and landscape evolution. To that aim, we use field and map observations and we apply the χ analysis of river profiles along the divide between the Ebro and Duero drainage basins. We show here that the contrasting excavation of the Ebro and Duero basins drives a reorganization of their drainage network through a series of captures, which resulted in the southwestward migration of their main drainage divide. Fluvial captures have a strong impact on drainage areas, fluxes, and their respective incision capacity. We conclude that drainage reorganization driven by the capture of the Duero basin rivers by the Ebro drainage system explains the first-order preservation of

    2015-04-01

    In this paper, issues of agricultural drainage systems are introduced and discussed from the views of their former, current and future roles and functioning in the Czech Republic (CR). A methodologically disparate survey was done on thirty-nine model localities in CR with different intensity and state of land drainage systems, aimed at description of commonly occurred problems and possible adaptations of agricultural drainage as perceived by farmers, land owners, landscape managers or by protective water management. The survey was focused on technical state of drainage, fragmentation of land ownership within drained areas as well as on possible conflicts between agricultural and environmental interests in a landscape. Achieved results confirmed that there is obviously an increasing need to reassess some functions of prevailingly single-purpose agricultural drainage systems. Drainage intensity and detected unfavourable technical state of drainage systems as well as the risks connected with the anticipated climate change from the view of possible water scarcity claims for a complex solution. An array of adaptation options for agricultural drainage systems is presented, aiming at enhancement of water retention time and improvement of water quality. It encompasses additional flow-controlling measures on tiles or ditches, or facilities for making selected parts of a drainage system inoperable in order to retain or slow down the drainage runoff, to establish water accumulation zones and to enhance water self-cleaning processes. However, it was revealed that the question of landowner parcels fragmentation on drained land in CR would dramatically complicate design and realization of these measures. Presented solutions and findings are propounded with a respect to contemporary and future state policies and international strategies for sustainable agriculture, water management and environment.

    An effective means to reducing the size and weight of future space vehicles is to replace present mostly single-phase thermal management systems with two-phase counterparts. By capitalizing upon both latent and sensible heat of the coolant rather than sensible heat alone, two-phase thermal management systems can yield orders of magnitude enhancement in flow boiling and condensation heat transfer coefficients. Because the understanding of the influence of microgravity on two-phase flow and heat transfer is quite limited, there is an urgent need for a new experimental microgravity facility to enable investigators to perform long-duration flow boiling and condensation experiments in pursuit of reliable databases, correlations and models. This presentation will discuss recent progress in the development of the Flow Boiling and Condensation Experiment (FBCE) for the International Space Station (ISS) in collaboration between Purdue University and NASA Glenn Research Center. Emphasis will be placed on the design of the flow boiling module and on new flow boiling data that were measured in parabolic flight, along with extensive flow visualization of interfacial features at heat fluxes up to critical heat flux (CHF). Also discussed a theoretical model that will be shown to predict CHF with high accuracy.

    Understanding the physics of internal transport barriers (ITBs) is a crucial issue in developing ITER relevant advanced tokamak scenarios. To gain new information on ITBs, RF power modulation experiments, mainly devoted to the study of electron heat transport through ITBs, have been performed on the JET tokamak. The main physics results have been reported in [1]. The present paper describes in detail the data analysis and numerical modelling work carried out for the interpretation of the experiments. ITBs located in the negative shear region behave as localized insulating layers able to stop the heat wave propagation, thus implying that the ITB is a region of low diffusivity characterized by a loss of stiffness. Various sources of spurious effects affecting the interpretation of the results are analysed and discussed. First principle based models have so far failed to predict the temperature profile in the first place, which prevented their application to modulation results, while empirical transport models have been set up and reproduce the major part of the data.

    The objective of this article is to describe the key areas of consideration for global/international advanced pharmacy practice experience (G/I APPE) preceptors, students and learning objectives. At the 2013 Annual Meeting of the American Association of Colleges of Pharmacy (AACP), the GPE SIG prepared and presented an initial report on the G/IAPPE initiatives. Round table discussions were conducted at the 2014 AACP Annual Meeting to document GPE SIG member input on key areas in the report. Literature search of PubMed, Google Scholar and EMBASE with keywords was conducted to expand this report. In this paper, considerations related to preceptors and students and learning outcomes are described. Preceptors for G/I APPEs may vary based on the learning outcomes of the experience. Student learning outcomes for G/I APPEs may vary based on the type of experiential site. Recommendations and future directions for development of G/IAPPEs are presented. Development of a successful G/I APPE requires significant planning and consideration of appropriate qualifications for preceptors and students.

    A high-brightness hydrogen/deuterium atomic beam source is presented. The apparatus, previously used in electron scattering experiments with tensor-polarized deuterium (Ferro-Luzzi et al., Phys. Rev. Lett. 77 (1996) 2630; van den Brand et al., Phys. Rev. Lett. 78 (1997) 1235; Zhou et al., Phys. Rev. Lett. 82 (1998) 687; Bouwhuis et al., Phys. Rev. Lett. 82 (1999) 3755), was configured as a source for internal target experiments to measure single- and double-polarization observables, with either polarized hydrogen or vector/tensor polarized deuterium. The atomic beam intensity was enhanced by a factor of ∼2.5 by optimizing the Stern-Gerlach focusing system using high tip-field (∼1.5 T) rare-earth permanent magnets, and by increasing the pumping speed in the beam-formation chamber. Fluxes of (5.9±0.2)x10 16 1 H/s were measured in a diameter 12 mmx122 mm compression tube with its entrance at a distance of 27 cm from the last focusing element. The total output flux amounted to (7.6±0.2)x10 16 1 H/s

    Full Text Available The CASE-IPY project, part of the larger POLENET initiative of geophysical observations for the International Polar Year, was built on our extensive experience of running seismological stations in Antarctica, both on rock sites (Dumont d’Urville station, and directly on the ice plateau (Concordia station. For CASE-IPY, we deployed 8 temporary seismic stations on the Antarctic plateau: 3 situated near Concordia itself (starting 2008, and the other 5 regularly spaced between Concordia and Vostok (2010-2012, following the maximum in ice topography. The technical problems we have encountered in our field deployments were essentially due to a combination of extreme environmental conditions and isolation of deployment sites. The 3 stations near Concordia were used as test sites to experiment different solutions, and to converge on a design for the 5 main stations. Results from the nearest stations, which transmit data regularly to Concordia, are very promising. The data recorded by our stations will be distributed widely in the scientific community. We expect them to be exploited essentially for structural studies involving Antarctica itself (its ice-cap, crust and lithosphere via receiver functions, noise correlation, and surface-wave tomography, but also for studies of the Earth’s core.

    International Standard Problems (ISP) organized by the OECD are defined as comparative exercises in which predictions with different computer codes for a given physical problem are compared with each other and with a carefully controlled experimental study. The main goal of ISP is to increase confidence in the validity and accuracy of analytical tools used in assessing the safety of nuclear installations. In addition, it enables the code user to gain experience and to improve his competence. This paper presents the results and assessment of ISP No. 36, which deals with the early core degradation phase during an unmitigated severe LWR accident in a Russian type VVER. Representatives of 17 organizations participated in the ISP using the codes ATHLET-CD, ICARE2, KESS-III, MELCOR, SCDAP/RELAP5 and RAPTA. Some participants performed several calculations with different codes. As experimental basis the severe fuel damage experiment CORA-W2 was selected. The main phenomena investigated are thermal behavior of fuel rods, onset of temperature escalation, material behavior and hydrogen generation. In general, the calculations give the right tendency of the experimental results for the thermal behavior, the hydrogen generation and, partly, for the material behavior. However, some calculations deviate in important quantities - e.g. some material behavior data - showing remarkable discrepancies between each other and from the experiments. The temperature history of the bundle up to the beginning of significant oxidation was calculated quite well. Deviations seem to be related to the overall heat balance. Since the material behavior of the bundle is to a great extent influenced by the cladding failure criteria a more realistic cladding failure model should be developed at least for the detailed, mechanistic codes. Regarding the material behavior and flow blockage some models for the material interaction as well as for relocation and refreezing requires further improvement.

    Providing food or nutrition supplements during hemodialysis (HD) may be associated with improved nutritional status and reduced mortality; however, despite these potential benefits, eating practices vary across countries, regions, and clinics. Understanding present clinic practices and clinician experiences with eating during HD may help outline best practices in this controversial area. Therefore, the objective of this study was to examine clinical practices and experiences related to eating during HD treatment. We surveyed clinicians about their clinic practices during the 2014 International Society of Renal Nutrition and Metabolism Conference. We received 73 responses from six continents. Respondents were primarily dietitians (71%) working at units housed in a hospital (63%). Sixty-one clinics (85%) allowed patients to eat during treatment, with 47 of these patients (65%) actively encouraging eating. Fifty-three clinics (73%) provided food during HD. None of the nine clinics from North America, however, provided food during treatment. The majority (47 clinics; 64%) provided supplements during treatment. Clinics in the hospital setting were more likely to provide food during treatment, whereas outpatient clinics were less likely to provide nutrition supplements (P≤ 0.05 for both). We also asked clinicians about their experience with six commonly cited reasons to restrict eating during treatment using a four-point scale. Clinicians responded they observed the following conditions "rarely" or "never": choking (98%), reduced Kt/V (98%), infection control issues (96%), spills or pests (83%), gastrointestinal issues (71%), and hypotension (62%). Our results indicate that while eating is common during treatment in some areas, disparities may exist in global practices, and most of the proposed negative sequelae of eating during HD are not frequently observed in clinical practice. Whether these disparities in practice can explain global differences in albumin warrants

    The Constrained Vapor Bubble (CVB) is a wickless, grooved heat pipe and we report on a full- scale fluids experiment flown on the International Space Station (ISS). The CVB system consists of a relatively simple setup a quartz cuvette with sharp corners partially filled with either pentane or an ideal mixture of pentane and isohexane as the working fluids. Along with temperature and pressure measurements, the two-dimensional thickness profile of the menisci formed at the corners of the quartz cuvette was determined using the Light Microscopy Module (LMM). Even with the large, millimeter dimensions of the CVB, interfacial forces dominate in these exceedingly small Bond Number systems. The experiments were carried out at various power inputs. Although conceptually simple, the transport processes were found to be very complex with many different regions. At the heated end of the CVB, due to a high temperature gradient, we observed Marangoni flow at some power inputs. This region from the heated end to the central drop region is defined as a Marangoni dominated region. We present a simple analysis based on interfacial phenomena using only measurements from the ISS experiments that lead to a predictive equation for the thickness of the film near the heated end of the CVB. The average pressure gradient for flow in the film is assumed due to the measured capillary pressure at the two ends of the liquid film and that the pressure stress gradient due to cohesion self adjusts to a constant value over a distance L. The boundary conditions are the no slip condition at the wall interface and an interfacial shear stress at the liquid- vapor interface due to the Marangoni stress, which is due to the high temperature gradient. Although the heated end is extremely complex, since it includes three- dimensional variations in radiation, conduction, evaporation, condensation, fluid flow and interfacial forces, we find that using the above simplifying assumptions, a simple successful

    From the very beginning of electro-nuclear programmes the need has become internationally obvious to develop systems aiming at automation and improvement of monitoring of the transients stressing the main mechanical components of nuclear units, by checking the conservativeness of the design no longer from a comparison of causes (temperature and pressure variations) but by directly assessing the results (stresses and linked damage). Prototypes of such systems have appeared since the middle of the 1980's mainly in France, the USA and Germany, and manufacturing them has since continued. Several years of development and on site testing of prototypes of fatigue measuring devices designed by the R and D Direction have enabled contacts with the developers of similar systems to be established and, in some cases, comparisons to be made. The experience accumulated in the use of such systems, both in France and abroad from now on makes a first experience feedback possible. The fatigue measuring device concept is based on a succession of elementary modules which enable the information received from the unit to be processed, first in the form of transient counting (transient meters), then in the form of mechanical diagnosis (fatigue monitoring systems). Among the systems in operation some provide actually only the transient meter part while others link transient meters and fatigue meters (EDF, EPRI and MITSUBISHI systems and some versions of the SIEMENS system). Moreover, numerous systems require, in addition to unit operation instrumentation, specific instrumentation located in monitored areas. The number of devices in operation has not stopped growing since the middle of the 80's to reach 53 systems working in 1996. The biggest developers are EPRI and its consultant Structural Integrity Associates (FatiguePro system), SIEMENS (FAMOS system) and EDF whose gradual implementation of SYSFAC from '96 is going to make its share particularly increase.

  6. Effects of peatland drainage management on peak flows

    Full Text Available Open ditch drainage has historically been a common land management practice in upland blanket peats, particularly in the UK. However, peatland drainage is now generally considered to have adverse effects on the upland environment, including increased peak flows. As a result, drain blocking has become a common management strategy in the UK over recent years, although there is only anecdotal evidence to suggest that this might decrease peak flows. The change in the hydrological regime associated with the drainage of blanket peat and the subsequent blocking of drains is poorly understood, therefore a new physics-based model has been developed that allows the exploration of the associated hydrological processes. A series of simulations is used to explore the response of intact, drained and blocked drain sites at field scales. While drainage is generally found to increase peak flows, the effect of drain blocking appears to be dependent on local conditions, sometimes decreasing and sometimes increasing peak flows. Based on insights from these simulations we identify steep smooth drains as those that would experience the greatest reduction in field-scale peak flows if blocked and recommend that future targeted field studies should be focused on examining surface runoff characteristics.

    Acute suppurative cholangitis is a severe inflammatory process of the bile duct occurred as result of partial or complete obstruction of the bile duct, and may manifest clinically severe form of disease, rapidly deteriorating to life-threatening condition. We analyzed emergency percutaneous transhepatic biliary drainage in 20 patients of acute suppurative cholangitis with biliary sepsis to evaluate the therapeutic effect and complication of the procedure. The underlying cause were 12 benign disease(stones) and eight malignant tumors and among eight malignant tumors, bile duct stones(n=4) and clonorchiasis(n=1) were combined. Percutaneous transhepatic biliary drainage was performed successfully in 17 of 20 patients resulting in improvement of general condition and failed in three patients. The procedure were preterminated due to the patient's condition in two and biliary-proto fistula was developed in one. After biliary decompression by percutaneous transhepatic biliary drainage, effective and successful elective surgery was performed in nine cases, which were seven biliary stones and two biliary cancer with stones. Our experience suggest that emergency percutaneous transhepatic biliary drainage is an initial and effective treatment of choice for acute suppurative cholangitis with sepsis and a safe alternative for nonsurgical treatment

    Since the 2011 Accreditation Council of Graduate Medical Education (ACGME) work hour rules for residents were implemented, 24-30 h call for interns has been replaced by shift work, including night-float. The impact of these changes on undergraduate medical education experiences in internal medicine has not been described. We aimed to determine the current status of medical students' overnight experiences in Internal Medicine clerkships and sub-internships, and to assess internal medicine educators' perceptions of the importance of overnight work during internal medicine rotations. In May 2014, the Clerkship Directors in Internal Medicine (CDIM) conducted its annual survey. Twenty-eight questions about student participation in overnight work and perceptions of the importance of overnight work (rated on 1-5 Likert scale, 1 = very unimportant and 5 =  ery important) were included. Descriptive statistics were used to summarize responses. Free text results were analyzed qualitatively. The response rate was 78 %. A minority of respondents reported students having any overnight experience during the clerkship (38.7 %) or the sub-internship (40.7 %). Only 5 % of respondents reported having students assigned to night-float rotations outside of clerkships or sub-internships. Respondents agreed that overnight experiences were more important during the sub-internship than the clerkship, 4.0 ± 1.1 vs. 3.2 ± 1.2, p intern in particular was an important chance to practice providing emergency cross coverage and other intern roles. In the era of ACGME duty hours, there is a need to further examine whether there is a role for increased overnight hospital experiences for medical students.

    The growth and drainage of active subglacial lakes in Antarctica has previously been inferred from analysis of ice surface altimetry data. We use a subglacial hydrology model applied to a synthetic Antarctic ice stream to examine internal controls on the filling and drainage of subglacial lakes. Our model outputs suggest that the highly constricted subglacial environment of our idealized ice stream, combined with relatively high rates of water flow funneled from a large catchment, can combine to create a system exhibiting slow-moving pressure waves. Over a period of years, the accumulation of water in the ice stream onset region results in a buildup of pressure creating temporary channels, which then evacuate the excess water. This increased flux of water beneath the ice stream drives lake growth. As the water body builds up, it steepens the hydraulic gradient out of the overdeepened lake basin and allows greater flux. Eventually this flux is large enough to melt channels that cause the lake to drain. Lake drainage also depends on the internal hydrological development in the wider system and therefore does not directly correspond to a particular water volume or depth. This creates a highly temporally and spatially variable system, which is of interest for assessing the importance of subglacial lakes in ice stream hydrology and dynamics.

    The research probes into the temporal-spatial process of drainage development of Loess Plateau on the basis of a carefully designed experiment. In the experiment, the development of a simulated loess watershed is tested under the condition of lab-simulated rainfall. A close-range photogrammetry survey is employed to establish a series of high precision and resolution DEM (Digit Elevation Model) of the simulated loess surface. Based on the established DEM, the erosion loss, the slope distribution, the topographic index , the gully-brink, and the drainage networks are all derived and discussed through comparison analysis and experimental validation. All the efforts aim at revealing the process and mechanism of erosion and drainage development of loess surface .This study demonstrates: 1) the stimulation result can effectively reflect the truth if those experimental conditions, i.e. loess soil structure, simulated rainfall, are adjusted in accord with true situation; 2) the remarkable character of the erosion and drainage up-growth of loess surface include the drainage traced to the source, the increased of the drainage's density, the enlarged of gully, the durative variety of multiple terrain factor's mean value and its distribution, such as slope and topographic index; 3) The slope spectrum is the more felicitous terrain factor for depicting the erosion and drainage development of loess surface, including the rule of erosion and evolution process. It is the new way and mean for studying the loess physiognomy.

    The Stratospheric Aerosol and Gas Experiment III on the International Space Station (SAGE III/ISS) mission will provide the science community with high-vertical resolution and nearly global observations of ozone, aerosols, water vapor, nitrogen dioxide, and other trace gas species in the stratosphere and upper-troposphere. SAGE III/ISS measurements will extend the long-term Stratospheric Aerosol Measurement (SAM) and SAGE data record begun in the 1970s. The multi-decadal SAGE ozone and aerosol data sets have undergone intense scrutiny and are considered the international standard for accuracy and stability. SAGE data have been used to monitor the effectiveness of the Montreal Protocol. Key objectives of the mission are to assess the state of the recovery in the distribution of ozone, to re-establish the aerosol measurements needed by both climate and ozone models, and to gain further insight into key processes contributing to ozone and aerosol variability. The space station mid-inclination orbit allows for a large range in latitude sampling and nearly continuous communications with payloads. The SAGE III instrument is the fifth in a series of instruments developed for monitoring atmospheric constituents with high vertical resolution. The SAGE III instrument is a moderate resolution spectrometer covering wavelengths from 290 nm to 1550 nm. Science data is collected in solar occultation mode, lunar occultation mode, and limb scatter measurement mode. A SpaceX Falcon 9 launch vehicle will provide access to space. Mounted in the unpressurized section of the Dragon trunk, SAGE III will be robotically removed from the Dragon and installed on the space station. SAGE III/ISS will be mounted to the ExPRESS Logistics Carrier-4 (ELC-4) location on the starboard side of the station. To facilitate a nadir view from this location, a Nadir Viewing Platform (NVP) payload was developed which mounts between the carrier and the SAGE III Instrument Payload (IP).

    This paper compares the traditional tools of calculation for a journal's efficacy and visibility with the new tools that have arrived from the Internet, social media and search engines. The examples concern publications of orthopaedic surgery and in particular International Orthopaedics. Until recently, the prestige of publications, authors or journals was evaluated by the number of citations using the traditional citation metrics, most commonly the impact factor. Over the last few years, scientific medical literature has developed exponentially. The Internet has dramatically changed the way of sharing and the speed of flow of medical information. New tools have allowed readers from all over the world to access information and record their experience. Web platforms such as Facebook® and Twitter® have allowed for inputs from the general public. Professional sites such as LinkedIn® and more specialised sites such as ResearchGate®, BioMed Central® and OrthoEvidence® have provided specific information on defined fields of science. Scientific and professional blogs provide free access quality information. Therefore, in this new era of advanced wireless technology and online medical communication, the prestige of a paper should also be evaluated by alternative metrics (altmetrics) that measure the visibility of the scientific information by collecting Internet citations, number of downloads, number of hits on the Internet, number of tweets and likes of scholarly articles by newspapers, blogs, social media and other sources of data. This article provides insights into altmetrics and informs the reader about current tools for optimal visibility and citation of their work. It also includes useful information about the performance of International Orthopaedics and the bias between traditional publication metrics and the new alternatives.

    The discourse about mental health problems among migrants and refugees tends to focus on adverse pre-migration experiences; there is less investigation of the environmental conditions in which refugee migrants live, and the contrasts between these situations in different countries. This cross-national study of two samples of Somali refugees living in London (UK) and Minneapolis, Minnesota, (USA) helps to fill a gap in the literature, and is unusual in being able to compare information collected in the same way in two cities in different countries. There were two parts to the study, focus groups to gather in-depth qualitative data and a survey of health status and quantifiable demographic and material factors. Three of the focus groups involved nineteen Somali professionals and five groups included twenty-eight lay Somalis who were living in London and Minneapolis. The quantitative survey was done with 189 Somali respondents, also living in London and Minneapolis. We used the MINI International Neuropsychiatric Interview (MINI) to assess ICD-10 and DSM-IV mental disorders. The overall qualitative and quantitative results suggested that challenges to masculinity, thwarted aspirations, devalued refugee identity, unemployment, legal uncertainties and longer duration of stay in the host country account for poor psychological well-being and psychiatric disorders among this group. The use of a mixed-methods approach in this international study was essential since the quantitative and qualitative data provide different layers and depth of meaning and complement each other to provide a fuller picture of complex and multi-faceted life situations of refugees and asylum seekers. The comparison between the UK and US suggests that greater flexibility of access to labour markets for this refugee group might help to promote opportunities for better integration and mental well-being.

Conclusion The use of a mixed-methods approach in this international study was essential since the quantitative and qualitative data provide different layers and depth of meaning and complement each other to provide a fuller picture of complex and multi-faceted life situations of refugees and asylum seekers. The comparison between the UK and US suggests that greater flexibility of access to labour markets for this refugee group might help to promote opportunities for better integration and mental well-being.

    Nuclear Company AREVA is proud to look back on versatile experience in successfully dismantling nuclear components. After performing several minor dismantling projects and studies for nuclear power plants, AREVA completed the order for dismantling of all remaining Reactor Pressure Vessel internals at German Boiling Water Reactor Wuergassen NPP in October '08. During the onsite activities about 121 tons of steel were successfully cut and packed under water into 200l- drums, as the dismantling was performed partly in situ and partly in an underwater working tank. AREVA deployed a variety of different cutting techniques such as band sawing, milling, nibbling, compass sawing and water jet cutting throughout this project. After successfully finishing this task, AREVA dismantled the cylindrical part of the Wuergassen Pressure Vessel. During this project approximately 320 tons of steel were cut and packaged for final disposal, as dismantling was mainly performed by on air use of water jet cutting with vacuum suction of abrasive and kerfs material. The main clue during this assignment was the logistic challenge to handle and convey cut pieces from the pressure vessel to the packing area. For this, an elevator was installed to transport cut segments into the turbine hall, where a special housing was built for final storage conditioning. At the beginning of 2007, another complex dismantling project of great importance was acquired by AREVA. The contract included dismantling and conditioning for final storage of the complete RPV Internals of the German Pressurized Water Reactor Stade NPP. Very similar cutting techniques turned out to be the proper policy to cope this task. On-site activities took place in up to 5 separate working areas including areas for post segmentation and packaging to perform optimized parallel activities. All together about 85 tons of Core Internals were successfully dismantled at Stade NPP until September '09. To accomplish the best possible on

    We have used dacryoscintigraphy to study the efficiency of the lacrimal system following the repair of a divided lower canaliculus in 4 children. This test has been reliable in evaluating lacrimal function and suggests that a canaliculus can be repaired and splinted satisfactorily. Our experience with dacryoscintigraphy confirms that it is a safe comfortable, and reliable method for studying the patency of the lacrimal drainage system

    resistances were tested, again to accommodate a large range of potential drainage flows rates. The experiment was continued until the Sorbicell's capacity was exhausted, which gave experimentation times from 6 to 34 days, while continuously changing the drainage flow rate to simulate field drainage conditions, and to test the range of the Flowcap. The laboratory testing yielded a very good linear correlation between drainage flow rates and Sorbicell sampling rates, giving r = 0.99 for both the Q25 and the Q256 Flowcap. The Sorbicells in this experiment were designed to measure NO3, but the Flowcap can be used with any Sorbicell and thus be used to measure any compound of interest. The Flowcap does not need housing, electricity, or maintenance and continuously register drainage volumes and contaminant loads for periods up to one month. This, in addition to the low cost of the monitoring system, enables large-scale monitoring of contaminant loads via tube drains, giving valuable data for the improvement of contaminant transport models. Further, these data will help select and evaluate the different mitigation option to improve water quality.

    Essential Skills in the Management of Surgical Cases (ESMSC) is a novel 3-day international undergraduate surgical masterclass. Its current curriculum (Cores integrated for Research-Ci4R) is built on a tetracore, multiclustered architecture combining high-fidelity and low-fidelity simulation-based learning (SBL), with applied and basic science case-based workshops, and non-technical skills modules. We aimed to report our experience in setting up ESMSC during the global financial crisis. We report the evolution of our curriculum's methodology and summarised the research outcomes related to the objective performance improvement of delegates, the educational environment of the course and the use of mixed-fidelity SBL. Feedback from the last three series of the course was prospectively collected and analysed using univariate statistics on IBM SPSS V.23. 311 medical students across the European Union (EU) were selected from a competitive pool of 1280 applicants during seven series of the course between 2014 and 2017. During this period, curriculum 14 s evolved to the final Ci4R version, which integrates a tetracore structure combining 32 stations of in vivo, ex vivo and dry lab SBL with small group teaching workshops. Ci4R was positively perceived across different educational background students (p>0.05 for any comparison). ESMSC is considered an innovative and effective multidisciplinary teaching model by delegates, where it improves delegates objective performance in basic surgical skills. Our experience demonstrates provision of high-quality and free surgical education during a financial crisis, which evolved through a dynamic feedback mechanism. The prospective recording and subsequent analysis of curriculum evolution provides a blueprint to direct development of effective surgical education courses that can be adapted to local needs. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    To assess the academic performance and experiences of local, international, and collaborative exchange students enrolled in a 4-year Australian bachelor of pharmacy degree program. Survey instruments exploring the demographics, background, and academic and cultural experiences of students during the program were administered in 2005 to students in all 4 years. Additionally, grades from each semester of the program for students (406 local, 70 international, 155 exchange) who graduated between 2002 and 2006 were analyzed retrospectively. The main differences found in the survey responses among the 3 groups were in students' motivations for choosing the degree program and school, with international and collaborative exchange students having put more thought into these decisions than local students. The average grades over the duration of the program were similar in all 3 demographic groups. However, local students slightly outperformed international students, particularly at the start of the year, whereas collaborative exchange students' grades mirrored those of local students during the 2 years prior to leaving their home country of Malaysia but more closely mirrored those of international students in the final 2 years after arriving on campus in Australia. Despite differences in academic backgrounds and culture, international and exchange students can perform well compared to local students in a bachelor of pharmacy program and were actually more satisfied than local students with the overall experience. Studying in a foreign country can negatively influence academic grades to a small extent and this is probably related to adjusting to the new environment.

    Six patients with 7 tuberculous psoas or ilio-psoas abscesses were treated by CT-guided catheter drainage and chemotherapy. The abscesses (5 unilateral and 1 bilateral) were completely drained using a posterior or lateral approach. The abscess volume was 70 to 700 ml (mean 300 ml) and the duration of drainage 5 to 11 days (mean 7 days). Immediate local symptomatic improvement was achieved in all patients, and there were no procedural complications. CT follow-up at 3 to 9 months showed normalization in 5 patients, 2 of whom are still in medical therapy. One patient, who did not take the medication regularly, had a recurrent abscess requiring new catheter drainage after which the fluid collection disappeared. Percutaneous drainage represents an efficient and attractive alternative to surgical drainage as a supplement to medical therapy in the management of patients with large tuberculous psoas abscesses.

    Full Text Available In 20 patients with cubitus varus, a clinical test suggested by Yamamoto et al (1985 was carried out to measure the internal rotation. Average internal rotation was found to be 37.5 +/- 9.390. A correction for internal rotation was carried out for all the patients having angle more than 20 degrees. Following osteotomy, post-operative Yamamoto′s angle was measured and was found to be 8.85 +/- 6.5. An experiment was carried out on postmortem human humerus with cubitus varus. The internal rotation was measured with Kirschner wires and was found to be 30 degrees. Osteotomy was carried out to eliminate varus and correct internal rotation. Radiographs taken before and after the osteotomy confirmed the correction. We conclude that this derotation has to be corrected and Yamamoto′s test should be used to assess the correction.

    Gastrectomy remains the primary therapeutic method for resectable gastric cancer. Thought of as an important measure to reduce post-operative complications and mortality, abdominal drainage was used widely after gastrectomy for gastric cancer in previous decades. The benefits of abdominal drainage have been questioned by researchers in recent years. The objectives of this review were to access the benefits and harms of routine abdominal drainage post gastrectomy for gastric cancer. We searched the Cochrane Controlled Trials Register (Central/CCTR) in The Cochrane Library (2010, Issue 10), including the Specialised Registers of the Cochrane Upper Gastrointestinal and Pancreatic Diseases (UGPD) Group; MEDLINE (via Pubmed, 1950 to October, 2010); EMBASE (1980 to October, 2010); and the Chinese National Knowledge Infrastructure (CNKI) Database (1979 to October, 2010). We included randomised controlled trials (RCTs) comparing abdominal drain versus no drain in patients who had undergone gastrectomy (not considering the scale of gastrectomy and the extent of lymphadenectomy; irrespective of language, publication status, and the type of drain). We excluded RCTs comparing one drain with another. From each trial, we extracted the data on the methodological quality and characteristics of the included studies, mortality (30-day mortality), re-operations, post-operative complications (pneumonia, wound infection, intra-abdominal abscess, anastomotic leak, drain-related complications), operation time, length of post-operative hospital stay and initiation of soft diet. For dichotomous data, we calculated the risk ratio (RR) and 95% confidence intervals (CI). For continuous data, we calculated mean differences (MD) and 95% CI. We tested heterogeneity using the Chi(2) test. We used a fixed-effect model for data analysis with RevMan software but we used a random-effects model if the P value of the Chi(2) test was less than 0.1. We included four RCTs involving 438 patients (220

    Treatment for achalasia has traditionally been Heller myotomy (HM). Despite its excellent efficacy rate, a number of patients remain symptomatic post-procedure. Limited data exist as to the best management for recurrence of symptoms post-HM. We present an international, multicenter experience evaluating the efficacy and safety of post-HM peroral endoscopic myotomy (POEM). Patients who underwent POEM post-HM from 13 centers from January 2012 to January 2017 were included as part of a prospective registry. Technical success was defined as successful completion of the myotomy. Clinical success was defined as an Eckardt score of ≤3 on 12-month follow up. Adverse events (AE) including anesthesia-related, operative, and postoperative complications were recorded. Fifty-one patients were included in the study (mean age 54.2, 47% male). Technical success was achieved in 100% of patients. Clinical success on long-term follow up was achieved in 48 patients (94%), with a mean change in Eckardt score of 6.25. Seven patients (13%) had AE: six experienced periprocedural mucosal defect treated endoscopically and two patients developed mediastinitis treated conservatively. For patients with persistent symptoms after HM, POEM is a safe salvation technique with good short-term efficacy. As a result of the challenge associated with repeat HM, POEM might become the preferred technique in this patient population. Further studies with longer follow up are needed. © 2017 Japan Gastroenterological Endoscopy Society.

  11. China: EDF's feedback experience of reactor operating is essential to win international markets

    2016-01-01

    The main assets of EDF on the Chinese nuclear power market is first, its very important feedback experience of reactor operations (EDF cumulates one year of reactor operations every week due to its fleet of 58 reactors), secondly the cooperation with China allowed China to enter nuclear energy in 1983 with the construction of the Daya Bay plant and now to develop its own technology: the CPR-1000 reactor. China is the world leader in terms of nuclear market dynamism with 30 reactors in operation, 24 reactors being built and 40 others planned. A new stage in the Franco-China cooperation would be to share relevant good practices in the managing of both French and Chinese fleets of reactors. EDF has upgraded its commercial international offer, it now proposes to cover all the stages of the nuclear power plant from site selection to plant deconstruction via construction, operation, maintenance and waste management which constitutes a commitment over a 100 year period.

    The Strata-1 experiment will study the evolution of asteroidal regolith through long-duration exposure of simulant materials to the microgravity environment on the International Space Station (ISS). Many asteroids feature low bulk densities, which implies high values of porosity and a mechanical structure composed of loosely bound particles, (i.e. the "rubble pile" model), a prime example of a granular medium. Even the higher-density, mechanically coherent asteroids feature a significant surface layer of loose regolith. These bodies are subjected to a variety of forces and will evolve in response to very small perturbations such as micrometeoroid impacts, planetary flybys, and the YORP effect. Our understanding of this dynamical evolution and the inter-particle forces involved would benefit from long-term observations of granular materials exposed to small vibrations in microgravity. A detailed understanding of asteroid mechanical evolution is needed in order to predict the surface characteristics of as-of-yet unvisited bodies, to understand the larger context of samples collected by missions such as OSIRIS-REx and Hayabusa 1 and 2, and to mitigate risks for both manned and unmanned missions to asteroidal bodies. Understanding regolith dynamics will inform designs of how to land and set anchors, safely sample/move material on asteroidal surfaces, process large volumes of material for in situ resource utilization (ISRU) purposes, and, in general, predict behavior of large and small particles on disturbed asteroid surfaces.

    Full Text Available The article is aimed at analysis and synthesis of the international experience as to the State support for creating the transport and logistics centers (TLCs. The causes for emergence of the first TLCs in Europe (60-80-ies of XX century were considered. Values of the LPI index for the countries occupying the first 40 positions of the ranking as of 2014 and of 2016 have been provided, and the major changes during this time have been analyzed. The ranking position of Ukraine is displayed separately. Features of the logistics infrastructure of nine countries with a high value of the LPI index have been considered, degree of the State involvement in the formation of the TLC network has been analyzed. It has been substantiated that creation of the transport and logistics centers allows to reduce the logistics costs of individual producers and contributes to enhancing the efficiency of operation of the national economy in general by attracting investments in the infrastructure development, increasing the number of jobs and tax revenues. The basic motifs that determine the interest of the State authorities in providing support for creating the transportation and logistics centers have been defined. Prospect for further research in this direction will be determining the efficiency of using the different models of the State support for creation and development of TLCs

    1993-02-01

    An second international comparison on measuring techniques of tritium production rates for fusion neutronics experiments (ICMT-2) has been performed. The purpose is to evaluate the measurement accuracy of tritium production rates in the current measurement techniques. Two 14 MeV neutron source facilities, FNS at JAERI-Japan and LOTUS at EPFL-Switzerland, were used for this purpose. Nine groups out of seven countries participated in this program. A fusion simulated blanket assembly of simple-geometry was served as the test bed at each facility, in which Li-containing samples from the participants were irradiated in an uniform neutron field. The tritium production rates were determined by the participants using their own ways by using the liquid scintillation counting method. Tritiated water sample with unknown but the same concentration was also distributed and its concentration was measured to make a common reference. The standard deviation of measured tritium production rates among participants was about 10 % for both FNS and LOTUS irradiation levels: 4x10 -13 T-atoms/Li-atom and 1.6x10 -12 T-atoms/Li-atom at a sample, respectively. This standard deviation exceeds the expected deviation of 5 % in this program. It is presumed that the deviation of 10 % is caused mainly by the systematic and unknown errors in a process of tritium extraction from the irradiated samples depending on each organization.

    2007-02-01

    This article aims to review the regulatory framework governing the Belgian ostomy appliance market in the light of the experience of Denmark, France, the Netherlands and Ontario (Canada) with regulation of ostomy appliances. Information about the regulatory framework was derived from the international literature, analysis of legal texts and a survey completed by national experts. The comparative analysis revealed that these countries have adopted varying approaches towards regulating their domestic ostomy appliance market. Strategies to keep down prices include public procurement in Denmark, maximum prices in France and exclusion of expensive appliances from reimbursement in the Netherlands. To contain public expenditure on ostomy appliances, consumption patterns are monitored in the Netherlands, the quantity of reimbursed appliances is limited in Belgium and public reimbursement is restricted in Ontario. Ostomy appliances are generally distributed by community pharmacies and medical equipment shops. In countries that emphasise home care delivery such as Denmark, domiciliary distributors dominate the market to the detriment of community pharmacies which do not seem to be able to offer this service at a competitive price. An avenue for reforming the Belgian ostomy appliance market is proposed which valorizes the role of ostomy care nurses in guiding the choice of ostomy appliances. Furthermore, it is recommended that a competitive tendering process determines the price of ostomy appliances, that reimbursement for service provision by distributors is separated from reimbursement of appliances, and that patients receive a fixed grant from the third-party payer to buy ostomy appliances.

    Kimrey, J.O.; Fayard, L.D.

    1984-01-01

    Drainage wells are used to inject surface waters directly into an aquifer, or shallow ground waters directly into a deeper aquifer, primarily by gravity. Such wells in Florida may be grouped into two broad types: (1) surface-water injection wells, and (2) interaquifer connector wells. Drainage wells of the first type are further categorized as either Floridan aquifer drainage wells or Biscayne aquifer drainage wells. Floridan aquifer drainage wells are commonly used to supplement drainage for urban areas in karst terranes of central and north Florida. Data are available for 25 wells in the Ocala, Live Oak, and Orlando areas that allow comparison of the quality of water samples from these Floridan aquifer drainage wells with allowable contaminant levels. Comparison indicates that maximum contaminant levels for turbidity, color, and iron, manganese, and lead concentrations are equaled or exceeded in some drainage-well samples, and relatively high counts for coliform bacteria are present in most wells. Biscayne aquifer drainage wells are used locally to dispose of stormwater runoff and other surplus water in southeast Florida, where large numbers of these wells have been permitted in Dade and Broward Counties. The majority of these wells are used to dispose of water from swimming pools or to dispose of heated water from air-conditioning units. The use of Biscayne aquifer drainage wells may have minimal effect on aquifer potability so long as injection of runoff and industrial wates is restricted to zones where chloride concentrations exceed 1,500 milligrams per liter. Interaquifer connector wells are used in the phosphate mining areas of Polk and Hillsborough Counties, to drain mines and recharge the Floridan aquifer. Water-quality data available from 13 connector wells indicate that samples from most of these wells exceed standards values for iron concentration and turbidity. One well yielded a highly mineralized water, and samples from 6 of the other 12 wells exceed

The process is explored on the level of atomic quantum dynamics both experimentally and theoretically, employing cold collisions at temperatures down to 10 Kelvin involving small molecules or also very large systems ranging up to biomolecules. Dissociative recombination (DR) and related processes, such as dissociative excitation, collisional cooling of vibrations and rotations, photodissociation via high-lying electronic states, resonant electron attachment, and electron-induced processes in large molecules and clusters, are studied by a variety of experimental methods, including stored and trapped molecular ions, plasma techniques such as stationary and flowing afterglow, and laser spectroscopic diagnostic of molecular excitations. The Sixth International Conference on Dissociative Recombination: Theory, Experiments and Applications (DR2004) was organized by the Research Group on Atomic and Molecular Physics with Stored Ions at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany, and held near Heidelberg in the town of Mosbach in July 2004. It was attended by about 90 scientists working in atomic and molecular physics, astrophysics, plasma- and biophysics. International Conferences on Dissociative Recombination and related processes were held before at Lake Louise, Alberta, Canada (1988), Saint Jacut, Brittany, France (1992), Ein Gedi, Israel (1995), Nässlingen, Stockholm Archipelago, Sweden (1999), and last within a symposium at the American Chemical Society meeting in Chicago, USA (2001). The presentations of this conference document a strong development of theoretical ideas towards the understanding of DR in particular in polyatomic

    Radiologically guided percutaneous catheter drainage was used in 38 patients to treat pleural empyemas (35 patients) and pulmonary abscesses (3 patients). Drainage was successful in 85.7% of empyemas including 11 cases with fistulous communications. Three percutaneously drained pulmonary abscesses required subsequent lobectomy. One patient died during the drainage procedure due to sepsis. No major complications related to the drainage procedure were observed. Guided percutaneous drainage proved to be a safe and successful alternative to closed drainage of pleural fluid collections. (orig.)

    We measured the Cu isotopic composition of primary minerals and stream water affected by acid mine drainage in a mineralized watershed (Colorado, USA). The ??65Cu values (based on 65Cu/63Cu) of enargite (??65Cu = -0.01 ?? 0.10???; 2??) and chalcopyrite (??65Cu = 0.16 ?? 0.10???) are within the range of reported values for terrestrial primary Cu sulfides (-1??? waters (1.38??? ??? ??65Cu ??? 1.69???). The average isotopic fractionation (??aq-min = ??65Cuaq - ??65Cumin, where the latter is measured on mineral samples from the field system), equals 1.43 ?? 0.14??? and 1.60 ?? 0.14??? for chalcopyrite and enargite, respectively. To interpret this field survey, we leached chalcopyrite and enargite in batch experiments and found that, as in the field, the leachate is enriched in 65Cu relative to chalcopyrite (1.37 ?? 0.14???) and enargite (0.98 ?? 0.14???) when microorganisms are absent. Leaching of minerals in the presence of Acidithiobacillus ferrooxidans results in smaller average fractionation in the opposite direction for chalcopyrite (??aq-mino = - 0.57 ?? 0.14 ???, where mino refers to the starting mineral) and no apparent fractionation for enargite (??aq-mino = 0.14 ?? 0.14 ???). Abiotic fractionation is attributed to preferential oxidation of 65Cu+ at the interface of the isotopically homogeneous mineral and the surface oxidized layer, followed by solubilization. When microorganisms are present, the abiotic fractionation is most likely not seen due to preferential association of 65Cuaq with A. ferrooxidans cells and related precipitates. In the biotic experiments, Cu was observed under TEM to occur in precipitates around bacteria and in intracellular polyphosphate granules. Thus, the values of ??65Cu in the field and laboratory systems are presumably determined by the balance of Cu released abiotically and Cu that interacts with cells and related precipitates. Such isotopic signatures resulting from Cu sulfide dissolution should be useful for acid mine drainage

  8. Improving the international system for operating experience feedback. INSAG-23. A report by the International Nuclear Safety Group

    International Nuclear Information System (INIS)

    2008-01-01

    The operational safety performance of nuclear facilities has, in general, improved notably over time throughout the world. This has been achieved, in part, through operating experience feedback (OEF) and the introduction of new technology. While the continued strong safety performance by operators is encouraging, safety significant events continue to recur in nuclear installations. This indicates that operators are not learning and applying the lessons that experience can teach us. This report focuses on systems that are operated by intergovernmental organizations with close contacts to national regulatory authorities. These systems provide an alternative network to the worldwide system employed by the operators of nuclear facilities known as the World Association of Nuclear Operators (WANO). The WANO system is restricted to its members, who have concluded that keeping the information exchanged confidential improves its usefulness. INSAG recognizes the merits of this approach, particularly in light of the primary responsibility of licensed operators for the safety of their facilities. Nevertheless, INSAG encourages WANO to share key safety lessons with national regulatory authorities and intergovernmental organization

    2018-01-01

    Use of agricultural subsurface drainage systems in the Prairie Pothole Region of North America continues to increase, prompting concerns over potential negative effects to the Region's vital wetlands. The U.S. Fish and Wildlife Service protects a large number of wetlands through conservation easements that often utilize standard lateral setback distances to provide buffers between wetlands and drainage systems. Because of a lack of information pertaining to the efficacy of these setback distances for protecting wetlands, information is required to support the decision making for placement of subsurface drainage systems adjacent to wetlands. We used qualitative graphical analyses and data comparisons to identify characteristics of subsurface drainage systems and wetland catchments that could be considered when assessing setback distances. We also compared setback distances with catchment slope lengths to determine if they typically exclude drainage systems from the catchment. We demonstrated that depth of a subsurface drainage system is a key factor for determining drainage setback distances. Drainage systems located closer to the surface (shallow) typically could be associated with shorter lateral setback distances compared with deeper systems. Subsurface drainage systems would be allowed within a wetland's catchment for 44–59% of catchments associated with wetland conservation easements in North Dakota. More specifically, results suggest that drainage setback distances generally would exclude drainage systems from catchments of the smaller wetlands that typically have shorter slopes in the adjacent upland contributing area. For larger wetlands, however, considerable areas of the catchment would be vulnerable to drainage that may affect wetland hydrology. U.S. Fish and Wildlife Service easements are associated with > 2,000 km2 of wetlands in North Dakota, demonstrating great potential to protect these systems from drainage depending on policies for installing

    A major factor affecting patients' length of hospitalisation following head and neck surgery remains the use of surgical drains. The optimal time to remove these drains has not been well defined. A routine practice is to measure the drainage every 24 h and remove the drain when daily drainage falls below 25 ml. This study aims to determine whether drainage measurement at shorter intervals decreases the time to drain removal and hence the length of in-patient stays. A 6-month prospective observational study was performed. The inclusion criteria were patients who underwent head and neck surgery without neck dissection and had a closed suction drain inserted. Drainage rates were measured at 8-hourly intervals. Drains were removed when drainage-rate was ≤ 1 ml/h over an 8-h period. A total of 43 patients were evaluated. The highest drainage rate occurred in the first 8 postoperative hours and decreased significantly in the subsequent hours. The median drainage rates at 8, 16, 24, 32 and 40 postoperative hours were 3.375, 1, 0, 0 and 0 ml/h, respectively. Applying our new removal criteria of ≤ 1 ml/h drainage rate, the drains were removed in 22 (51%) patients at the 16th postoperative hour; 37 (86%) were removed by 24 h after operation. In comparison, only nine (20.9%) patients could potentially be discharged the day after surgery if previous criteria of ≤ 25 ml/24-h were used to decide on drain removal. Our 8-hourly drainage-rate monitoring has facilitated safe earlier discharge of an additional 28 (65%) patients on the day after surgery. This has led to improvement in patient care, better optimisation of hospital resources and resulted in positive economic implications to the department.

    2008-12-01

    A large multi-institutional international field experiment (ECORS Truc Vert'08) was conducted Feb-April 2008 on the southern part of the French Atlantic coastline. More than 120 scientists, students and technicians participated to this effort coming from 3 continents and 6 countries : Australia (University of New South Wales), France (SHOM, University Bordeaux I, University Pau et Pays de l'Adour, University Sud-Toulon Var, University Joseph Fourier, University Perpignan, BRGM, University Lyon 1), Great Britain (Plymouth University), New Zealand (NIWA), The Netherlands (Delft University of Technology, University of Utrecht) and USA (Naval Postgraduate School, University of Miami, Franklin and Marshall College). Truc Vert beach is a high-energy, dynamic, macrotidal, double-barred beach representative of most of the beaches on this 250 km long coastline. The inner bar can go through all the states within the intermediate classification and usually exhibits a transverse bar and rip morphology (380 m alongshore wavelength). The outer bar is changeable from linear to crescentic (720 m alongshore wavelength). The goals were to measure the hydrodynamic processes, sedimentary processes and morphologic responses on a macrotidal beach during energetic wave conditions and covering a large spectrum of spatial and temporal scales. This dataset will facilitate the validation of surf zone wave, hydrodynamic and morphodynamic models, it will lend insight into the morphodynamic evolution of three dimensional beaches and it will fill the gaps in previous nearshore data sets. A wide range of unique instrumentation was used including continuously sampled 2Hz high-resolution surfzone video cameras, daily topographic surveys, bathymetric surveys from the French naval vessels and personal watercrafts, high frequency velocity and pressure sensors, acoustic Doppler current profilers, sediment transport devices, sand porosity and grain size devices, and position-tracking drifters

    NASA is investigating a range of future human spaceflight missions, including both Mars-distance and Near Earth Object (NEO) targets. Of significant importance for these missions is the balance between crew autonomy and vehicle automation. As distance from Earth results in increasing communication delays, future crews need both the capability and authority to independently make decisions. However, small crews cannot take on all functions performed by ground today, and so vehicles must be more automated to reduce the crew workload for such missions. NASA's Advanced Exploration Systems Program funded Autonomous Mission Operations (AMO) project conducted an autonomous command and control experiment on-board the International Space Station that demonstrated single action intelligent procedures for crew command and control. The target problem was to enable crew initialization of a facility class rack with power and thermal interfaces, and involving core and payload command and telemetry processing, without support from ground controllers. This autonomous operations capability is enabling in scenarios such as initialization of a medical facility to respond to a crew medical emergency, and representative of other spacecraft autonomy challenges. The experiment was conducted using the Expedite the Processing of Experiments for Space Station (EXPRESS) rack 7, which was located in the Port 2 location within the U.S Laboratory onboard the International Space Station (ISS). Activation and deactivation of this facility is time consuming and operationally intensive, requiring coordination of three flight control positions, 47 nominal steps, 57 commands, 276 telemetry checks, and coordination of multiple ISS systems (both core and payload). Utilization of Draper Laboratory's Timeliner software, deployed on-board the ISS within the Command and Control (C&C) computers and the Payload computers, allowed development of the automated procedures specific to ISS without having to certify

    The number of internationally educated nurses is increasing in the Canadian workforce. Recruitment of internationally educated nurses is often seen as a solution to ongoing nursing shortages. However, international recruitment needs to be accompanied by strategies to ensure long-term retention. One of the criteria for successful retention is the availability and accessibility of career advancement and educational opportunities. Little research exists on the opportunities for career advancement and education for internationally educated nurses in Canada. This interpretive descriptive study was conducted to look at the perceptions of internationally educated nurses regarding career advancement and educational opportunities in Alberta, Canada. Eleven internationally educated nurses, working as registered nurses in Alberta, were interviewed using semi-structured interviews. Five themes were identified: motherhood as a priority, communication and cultural challenges, process of skill recognition, perceptions of opportunity and need for mentorship.

    Food-borne diseases are attracting a lot of attention in Vietnam as a result of repeated episodes of adulterated and unsafe food. In this paper, we provide some perspectives on food safety in Vietnam from the point of view of an international research institution working on food safety with partners in the country. We argue that one of the key issues of food safety in Vietnam is that certain food value chain stakeholders lack ethics, which leads to the production and trading of unsafe foods in order to make profits irrespective of adverse health effects on consumers. In turn, the shortfall in ethical behaviours around food can be attributed to a lack of incentives or motivating factors.Although food safety causes panic in the population, it is unclear how much contaminated food contributes to the burden of food-borne diseases and food poisonings in Vietnam. However, globally, the biggest health problem associated with food are infections from consuming food contaminated with viruses, bacteria or parasites. A major food safety challenge is the inappropriate way of communicating food risks to the public. Another key constraint is the inherent difficulty in managing food in wet markets and from smallholder production. On the other hand, local foods, and local food production and processing are an important cultural asset as well as being essential to food safety, and these aspects can be put at risk if food safety concerns motivate consumers to purchase more imported foods.In this paper, we also discuss good experiences in food safety management from other countries and draw lessons learnt for Vietnam on how to better deal with the current food safety situation.
