    Full Text Available The paper treats the area of Jodna spa in Novi Sad, which largely coincides with Futoški park, making with it the indissoluble unity. The main problem in the functioning of the Jodna psa is the fact that in legal sense Jodna spa does not exists, and in spatial sense there are still all of its content. The case of the paper is Jodna spa area, which includes the Special Hospital for Rheumatic Diseases, Hotel 'Park', Sports Center 'Sajmište' and Futoški park, which integrate them. The question of the Jodna spa planning, as well as the modern city recreation, spa and tourist center, is the goal of this paper. For this purpose it was necessary to show the historical background of the development of Jodna spa, to make the assessment of the state, critically analyze spatial plans which treat it and provide concrete suggestions for its design and equipping.

    2013-01-01

    The New Mexico Department of Health (NMDOH) investigated the cause of two cases of hypersensitivity pneumonitis (HP) in spa maintenance workers with laboratory confirmed Mycobacterium avium complex (MAC). The investigation occurred in tandem with worker protection and swimming pool regulatory investigations by the New Mexico Environment Department at the spa where the workers were employed. The investigation was conducted in order to identify unreported cases, exposure source(s), and to prevent further worker exposure. NMDOH surveyed 57 spa employees about symptoms and exposures, categorized jobs according to self-reported exposure to water, and computed odds ratios for symptom reporting by exposure category. Environmental isolates from spa water and filter swabs were cultured and compared to patient isolates by the Environmental and Applied Microbiology Team, Centers for Disease Control and Prevention (CDC). Workers with the highest exposure reported more HP-like symptoms (OR = 9.6), as did intermediate exposure workers (OR = 6.5), compared to workers with no aerosolized water exposure. Two of 13 environmental isolates were closely related to one of the patient isolates. Workers were likely exposed during spray cleaning of cartridge filters in a poorly ventilated work space. Recommendations include inhibiting organism growth in spa systems, assuring the use of respiratory protection, and adequately ventilating work spaces where filters and equipment are cleaned.

    One of the most important elements on the recovery of a small hydro-power plant is the electro-mechanical equipment (turbine-alternator), since the cost of the equipment means a high percentage of the total budget of the plant. The present paper intends to develop a series of equations which determine its cost from basic parameters such as power and net head. These calculations are focused at a level of previous study, so it will be necessary to carry out the engineering project and request a budget to companies specialized on the construction of electro-mechanical equipment to know its cost more accurately. Although there is a great diversity in the typology of turbines and alternators, data from manufacturers which cover all the considered range have been used. The above equations have been developed for the most common of turbines: Pelton, Francis, Kaplan and semiKaplan for a power range below 2 MW. The obtained equations have been validated with data from real installations which have been subject to analysis by engineering companies working on the assembly and design of small plants. (author)

    Canada has had a long and successful record of hydroelectric power development since the first hydraulic generators were installed at Chaudiere Falls near Ottawa in 1881. Canadian hydro engineers have demonstrated their ability to develop and manage higher voltages, longer transmission networks, larger projects, remote sites, and undersea cable technology. Canada has earned a reputation for excellence in the hydro industry and is successful at exporting its expertise to develop hydro resources in the international market. A prominent example is provided by the Three Gorges Project in China, for which the Chinese Ministry of Energy searched for the best foreign engineers to prepare a feasibility report. A Canadian team that integrated the expertise of hydro consultants, utilities, and major equipment suppliers was chosen to prepare the report, winning over teams from the USA, Brazil, and Europe. Success in this initiative is attributed to Canada's ability to demonstrate the favorable application of new technology at James Bay. Domestic hydro projects are thus seen as crucial in efforts to expand into international markets. However, Canada's new completed hydro capacity has fallen dramatically since 1986, and Canadian hydro contractors have tended to remain domestic operators with little incentive to enter foreign markets. By having the foresight to begin new hydro developments now, Canada would benefit from increased employment and orders for equipment, and would ensure a continuing base of technical expertise and innovation in the electrical industry. 2 figs

    2015-10-31

    Brigham City owns and operates its own municipal power system which currently includes several hydroelectric facilities. This project was to update the efficiency and capacity of current hydro production due to increased water flow demands that could pass through existing generation facilities. During 2006-2012, this project completed efficiency evaluation as it related to its main objective by completing a feasibility study, undergoing necessary City Council approvals and required federal environmental reviews. As a result of Phase 1 of the project, a feasibility study was conducted to determine feasibility of hydro and solar portions of the original proposal. The results indicated that the existing Hydro plant which was constructed in the 1960’s was running at approximately 77% efficiency or less. Brigham City proposes that the efficiency calculations be refined to determine the economic feasibility of improving or replacing the existing equipment with new high efficiency equipment design specifically for the site. Brigham City completed the Feasibility Assessment of this project, and determined that the Upper Hydro that supplies the main culinary water to the city was feasible to continue with. Brigham City Council provided their approval of feasibility assessment’s results. The Upper Hydro Project include removal of the existing powerhouse equipment and controls and demolition of a section of concrete encased penstock, replacement of penstock just upstream of the turbine inlet, turbine bypass, turbine shut-off and bypass valves, turbine and generator package, control equipment, assembly, start-up, commissioning, Supervisory Control And Data Acquisition (SCADA), and the replacement of a section of conductors to the step-up transformer. Brigham City increased the existing 575 KW turbine and generator with an 825 KW turbine and generator. Following the results of the feasibility assessment Brigham City pursued required environmental reviews with the DOE and

  10. Provincial hydro expansions

    Energy Technology Data Exchange (ETDEWEB)

    Froschauer, K J

    1993-01-01

    A study of the development of five provincial hydroelectric utilities in Canada indicates that power companies and the state invited manufacturers to use hydroelectricity and natural resources in order to diversify provincial economies. These hydro expansions also show that utilities and government designed hydro projects to serve continental requirements; serving both objectives became problematic. It is argued that when the Canadian state and firms such as utilities use hydro expansions to serve both continentalism and industrialization, then at best they foster dependent industrialization and staple processing. At worst, they overbuild the infrastructure to generate provincial surplus energy for continental, rather than national, integration. Hydro developments became subject to state intervention in Canada mainly through the failures of private utilities to provide power for the less-lucrative industrial markets within provincial subregions. Although the state and utilities invited foreign firms to manufacture hydro equipment within the provinces and others to use electricity to diversify production beyond resource processing, such a diversification did not occur. Since 1962, ca 80% of industrial energy was used to semi-process wood-derived products, chemicals, and metals. The idea for a national power network became undermined by interprovincial political-economic factors and since 1963, the federal national/continential power policy prevailed. 187 refs., 6 figs., 52 tabs.

  11. SP-A binding sites on bovine alveolar macrophages.

    Plaga, S; Plattner, H; Schlepper-Schaefer, J

    1998-11-25

    Surfactant protein A (SP-A) binding to bovine alveolar macrophages was examined in order to characterize SP-A binding proteins on the cell surface and to isolate putative receptors from these cells that could be obtained in large amounts. Human SP-A, unlabeled or labeled with gold particles, was bound to freshly isolated macrophages and analyzed with ELISA or the transmission electron microscope. Binding of SP-A was inhibited by Ca2+ chelation, by an excess of unlabeled SP-A, or by the presence of 20 mg/ml mannan. We conclude that bovine alveolar macrophages expose binding sites for SP-A that are specific and that depend on Ca2+ and on mannose residues. For isolation of SP-A receptors with homologous SP-A as ligand we isolated SP-A from bovine lung lavage. SDS-PAGE analysis of the purified SP-A showed a protein of 32-36 kDa. Functional integrity of the protein was demonstrated. Bovine SP-A bound to Dynabeads was used to isolate SP-A binding proteins. From the fractionated and blotted proteins of the receptor preparation two proteins bound SP-A in a Ca2+-dependent manner, a 40-kDa protein showing mannose dependency and a 210-kDa protein, showing no mannose sensitivity.

  14. Toronto Hydro annual report, 1992

    International Nuclear Information System (INIS)

    1993-01-01

    Toronto Hydro is the electric utility serving about 219,000 customers in Toronto, Ontario. In 1992, the utility purchased 9.6 billion kWh of electricity from Ontario Hydro, down 3.6% from 1990. Energy sales totalled 9.2 billion kWh, down 4.1% from 1990. Retail electricity rates increased an average of 6.7% in 1992, in spite of an increase in Ontario Hydro's wholesale rate by 8.2%, due to better than anticipated financial results and cost-control measures. The decline in electricity purchases and sales are attributed to economic factors, which also contributed to an increase in the utility's provision for bad debts. The third year of a 13.8-kV conversion project was completed in 1992; this project is converting the existing 4 kV distribution system to the higher voltage since maintenance and repair of the existing system is costly and the equipment is becoming less reliable. New construction, refurbishing, and modernization of equipment were performed at a number of substations. Other improvements in 1992 are reported in the areas of management and engineering systems, personnel policies, work safety, and energy management. Financial statements are included. 11 figs., 4 tabs

  19. Health tourism in a Czech health spa.

    Speier, Amy R

    2011-04-01

    This paper is about the changing shape of health tourism in a Czech spa town. The research focuses on balneotherapy as a traditional Czech healing technique, which involves complex drinking and bathing therapies, as it is increasingly being incorporated into the development of a Czech health tourism industry. Today, the health tourism industry in Mariánske Lázne is attempting to 'harmoniously' combine three elements--balneology, travel and business activities. One detects subtle shifts and consequent incongruities as doctors struggle for control over the medical portion of spa hotels. At the same time, marketing groups are creating new packages for a general clientele, and the implementation of these new packages de-medicalizes balneotherapy. Related to the issue of the doctor's authority in the spa, the changes occurring with the privatization of tourism entails the entrance of 'tourists' to Mariánske Lázne who are not necessarily seeking spa treatment but who are still staying at spa hotels. There is a general consensus among spa doctors and employees that balneotherapy has become commodified. Thus, while balneotherapy remains a traditional form of therapy, the commercial context in which it exists has created a new form of health tourism.

ICSI patients with the lowest SPA scores had significantly higher incidences of Sthan did patients in the other SPA groups. Sperm quality is higher with better SPA scores. Poor sperm quality has increased incidence of chromosomal abnormalities and is associated with early fetal loss. Couples with negative SPA are candidates for preimplantation genetic diagnosis, to reduce the incidence of SAB.

  6. Phenotypical analysis of the Lactobacillus rhamnosus GG fimbrial spaFED operon: surface expression and functional characterization of recombinant SpaFED pili in Lactococcus lactis.

    Directory of Open Access Journals (Sweden)

    Johanna Rintahaka

    Full Text Available A noticeable genomic feature of many piliated Gram-positive bacterial species is the presence of more than one pilus-encoding operon. Paradigmatically, the gut-adapted Lactobacillus rhamnosus GG strain contains two different fimbrial operons in its genome. However, whereas one of these operons (called spaCBA is encoding for the functionally mucus-/collagen-binding SpaCBA pilus, for the other operon (called spaFED any native expression of the SpaFED-called pili is still the subject of some uncertainty. Irrespective of such considerations, we decided it would be of relevance or interest to decipher the gross structure of this pilus type, and as well assess its functional capabilities for cellular adhesion and immunostimulation. For this, and by following the approach we had used previously to explicate the immuno-properties of SpaCBA pili, we constructed nisin-inducible expression clones producing either wild-type or SpaF pilin-deleted surface-assembled L. rhamnosus GG SpaFED pili on Lactococcus lactis cells. Using these piliated lactococcal constructs, we found that the pilin-polymerized architecture of a recombinant-produced SpaFED pilus coincides with sequence-based functional predictions of the related pilins, and in fact is prototypical of those other sortase-dependent pilus-like structures thus far characterized for piliated Gram-positive bacteria. Moreover, we confirmed that among the different pilin subunits encompassing spaFED operon-encoded pili, the SpaF pilin is a main adhesion determinant, and when present in the assembled structure can mediate pilus binding to mucus, certain extracellular matrix proteins, and different gut epithelial cell lines. However, somewhat unexpectedly, when recombinant SpaFED pili are surface-attached, we found that they could not potentiate the existing lactococcal cell-induced immune responses so elicited from intestinal- and immune-related cells, but rather instead, they could dampen them. Accordingly, we

    Full Text Available Two forms of tourism, which are represented to a large extent in the world, are spa and wellness tourism. In Serbia, spa and wellness tourism are not sufficiently used, although there are excellent conditions. During twenty century the state was paying more attention and money on the sea and river tourism. However, the separation of Serbia and Montenegro in two independent counties had left Serbia without an entrance to the Adriatic Sea, so development of other tourist products and destinations became an imperative for survival and existence in the tourist map of Europe and the world. The paper presents the basic aims and policies of development of spa tourism in Serbia and data obtained in the survey regarding quality of services provided in some spa towns in Serbia. Based on the results to which the research occurred, authors wished to point out main activities and tasks that the state uses in creating a development strategy of spa tourism, the programs that have already been taken, so as the influence of the economic crisis to spa tourism.

    2018-04-09

    Herbal spa treatments are favorite recreational activities throughout the world. The water in spas is often disinfected to control pathogenic microorganisms and guarantee hygiene. However, chlorinated water may cause the formation of disinfection byproducts (DBPs). Although there have been many studies on DBP formation in swimming pools, the role of organic matter derived from herbal medicines applied in herbal spa water has been largely neglected. Accordingly, the present study investigated the effect of herbal medicines on the formation of trihalomethanes (THMs) in simulated herbal spa water. Water samples were collected from a spa pool, and then, disinfection and herbal addition experiments were performed in a laboratory. The results showed that the organic molecules introduced by the herbal medicines are significant precursors to the formation of THMs in spa pool water. Since at least 50% of THMs were produced within the first six hours of the reaction time, the presence of herbal medicines in spa water could present a parallel route for THM exposure. Therefore, despite the undeniable benefits of herbal spas, the effect of applied herbs on DBP formation in chlorinated water should be considered to improve the water quality and health benefits of spa facilities.

    Staphylococcus aureus is a major human pathogen responsible for increasing the prevalence of community- and hospital-acquired infections. Protein A (SpA) is a key virulence factor of S. aureus and is highly conserved. Sequencing of the variable-number tandem-repeat region of SpA (spa typing......) provides a rapid and reliable method for epidemiological studies. Rarely, non-spa-typeable S. aureus strains are encountered. The reason for this is not known. In this study, we characterized eight non-spa-typeable bacteremia isolates. Sequencing of the entire spa locus was successful for five strains...... and revealed various mutations of spa, all of which included a deletion of immunoglobulin G binding domain C, in which the upper primer for spa typing is located, while two strains were truly spa negative. This is the first report demonstrating that nontypeability of S. aureus by spa sequencing is due either...

    Hydro-Quebec generates, transmits and distributes electricity mainly produced by renewable energy sources. Its sole shareholder is the Quebec government. This annual report reviewed the operations of Hydro-Quebec, and provided data on energy sales, production and details of the utility's environmental programs. Information on Hydro-Quebec subsidiaries in 2005 was presented in the following separate sections: Hydro-Quebec Production; Hydro-Quebec TransEnergie; Hydro-Quebec Distribution; Hydro-Quebec Equipement; and the Societe d'energie de la Baie James. In 2005, Hydro-Quebec Distribution signed contracts for an initial block of 990 MW of wind power and issued a tender call for an additional 2000 MW of wind power. A generator balancing service was created and authorized by the Regie de l'energie. Hydro-Quebec customers have achieved energy savings of nearly 450 GWh in 2005. The commissioning of Toulnustouc generating station was achieved 5 months ahead of schedule. The 526 MW facility will generate 2.7 TWh annually. Work at the Chute-Allard and Rapide-des-Coeurs sites has continued, as well as construction at Mercier and Peribonka and Eastmain-1. Income from continuing operations came to $2.25 billion, a $124 million increase that was attributed to a rise in domestic sales and net short-term exports. The income was offset by higher pension expenses, depreciation and amortization, as well as by cost of supply on external markets and financial expenses. All other operating expenses were lower than in 2004. Capital spending for the transmission system reached its highest level since 1997, with $793 million invested, including $336 million to meet growth. Data on the company's financial performance, executive changes and reorganization were provided. Financial statements included a review and analysis of financial transactions, an auditor's report, as well as customary notes to the consolidated financial statement including balance sheets, assets, liabilities and

    1999-01-01

    An operational and financial review of Hydro Mississauga for fiscal year 1998 is presented. Hydro Mississauga has been serving the municipality of Mississauga, Ontario for the past 82 years. In 1998, Hydro Mississauga went through major restructuring to include a new competitive 'Services' Division which offers a wide range of competitive products and services. Despite deregulation and restructuring, quality of service was maintained and all-time performance records were set for company safety and system reliability. Operating costs were also cut and low rates continued. The residential rate freeze will be extended for a sixth straight year into 1999. Consolidated financial statements show that in 1998 Hydro Mississauga was 100 per cent debt free. One of the top priorities for the utility in 1998 was to get ready to deal with any problem that might arise as we roll over into the year 2000. The utility has completed an inventory of all computer software and equipment and has taken measures such as remediation, testing and getting vendor assurances. tabs., figs

  5. SPA: a probabilistic algorithm for spliced alignment.

    Directory of Open Access Journals (Sweden)

    2006-04-01

    Full Text Available Recent large-scale cDNA sequencing efforts show that elaborate patterns of splice variation are responsible for much of the proteome diversity in higher eukaryotes. To obtain an accurate account of the repertoire of splice variants, and to gain insight into the mechanisms of alternative splicing, it is essential that cDNAs are very accurately mapped to their respective genomes. Currently available algorithms for cDNA-to-genome alignment do not reach the necessary level of accuracy because they use ad hoc scoring models that cannot correctly trade off the likelihoods of various sequencing errors against the probabilities of different gene structures. Here we develop a Bayesian probabilistic approach to cDNA-to-genome alignment. Gene structures are assigned prior probabilities based on the lengths of their introns and exons, and based on the sequences at their splice boundaries. A likelihood model for sequencing errors takes into account the rates at which misincorporation, as well as insertions and deletions of different lengths, occurs during sequencing. The parameters of both the prior and likelihood model can be automatically estimated from a set of cDNAs, thus enabling our method to adapt itself to different organisms and experimental procedures. We implemented our method in a fast cDNA-to-genome alignment program, SPA, and applied it to the FANTOM3 dataset of over 100,000 full-length mouse cDNAs and a dataset of over 20,000 full-length human cDNAs. Comparison with the results of four other mapping programs shows that SPA produces alignments of significantly higher quality. In particular, the quality of the SPA alignments near splice boundaries and SPA's mapping of the 5' and 3' ends of the cDNAs are highly improved, allowing for more accurate identification of transcript starts and ends, and accurate identification of subtle splice variations. Finally, our splice boundary analysis on the human dataset suggests the existence of a novel non

    British Columbia Hydro (BC Hydro) published this document which measures the environmental, social and economic performance of the company. It is a complement to BC Hydro's 2002 Annual Report. The report was prepared to better understand the company's business in terms of its commitment to being an environmentally, socially, and economically responsible company (the three bottom lines). BC Hydro proved its ability to integrate the three bottom lines in decision making processes by carefully examining the environmental, social and economical impacts of programs such as Power Smart, Green and Alternative Energy, and Water Use Planning. All indicators point to BC Hydro achieving its commitment of providing a minimum of 10 per cent of new demand through 2010 with new green energy sources. Water Use Plans were developed for hydroelectric generating stations, and they should all be in place by 2003. Efficiencies realised through the Power Smart program offset the increases in greenhouse gas associated with increased energy demand. Juvenile sturgeon raised in a hatchery were released into the Columbia River in May 2002. The completion of a 40-kilometre trail on the Sunshine Coast was helped by a financial contribution from BC Hydro in the amount of 23,000 dollars. Safety improvements were implemented at eight facilities, such as dam remediation, dam surveillance and instrumentation updates. Scholarships were awarded across the province, along with additional donations to non-profit organizations. Co-op positions were provided for 150 students. Internal energy efficiency programs were successful. Planning is under way for significant maintenance work and equipment replacement projects as the transmission and distribution infrastructure ages. The number of reported indicators was expanded this year. In turn, they were aligned with the revised Global Reporting Initiative (GRI) guidelines. tabs

    The spa of Bizovac is located 20 km on the west of Osijek in east Croatia. Radon concentrations in the air and water of the Bizovac spa were measured by the Radhome silicon detector and the average values were obtained as 70 Bq/m 3 in the indoor pool, 40 Bq/m 3 in the hotel room and 135 Bq/m 3 in the closed therapeutic bathroom. A special experiment was performed in a closed therapeutic bathroom by three bathtubes filled up with geothermal water as well as normal (potable) one from water-supply. Using measured radon concentrations in air by Radhome detector under the mentioned conditions in the closed bathroom, radon concentrations were assessed for the geothermal water as 25.3 Bq/m 3 and 2.7 Bq/m 3 for potable water. Radon in potable water, measured by the sampling glass ampoule and scintillation cell, had the concentration of 3.5 Bq/m 3 . The radon transfer factor from water to air in the indoor pool and therapeutic bathroom was 10 and 40 times higher than for normal dwelling factor (10 -4 ), respectively. The effective dose equivalent of inhaled radon for permanent personnel under the worst conditions in the spa (closed therapeutic bathroom) was 5.4 mSv/y, but visitors spending two weeks in the Bizovac spa could receive the dose of 77 μSv.

    Ontario Hydro have been using ultrasonic test (UT) technique to inspect steam generator (SG) tubes since 1993. The UT technique has higher sensitivity in detecting flaws in SG tubes and can characterize the flaws with higher accuracy. Although an outside contractor was used initially, Ontario Hydro has been using a self-developed system since 1995. The TRUSTIE system (Tiny Rotating UltraSonic Tube Inspection Equipment) was developed by Ontario Hydro Technologies specifically for 12.7 mm outside diameter (OD) tubes, and later expanded to larger tubes. To date TRUSTIE has been used in all of Ontario Hydro's nuclear generating stations inspecting for flaws such as pitting, denting, and cracks at top-of-tubesheet to the U-bend region. (author)

    2016-03-01

    Full Text Available Spam reviews are increasingly appearing on the Internet to promote sales or defame competitors by misleading consumers with deceptive opinions. This paper proposes a co-training approach called CoSpa (Co-training for Spam review identification to identify spam reviews by two views: one is the lexical terms derived from the textual content of the reviews and the other is the PCFG (Probabilistic Context-Free Grammars rules derived from a deep syntax analysis of the reviews. Using SVM (Support Vector Machine as the base classifier, we develop two strategies, CoSpa-C and CoSpa-U, embedded within the CoSpa approach. The CoSpa-C strategy selects unlabeled reviews classified with the largest confidence to augment the training dataset to retrain the classifier. The CoSpa-U strategy randomly selects unlabeled reviews with a uniform distribution of confidence. Experiments on the spam dataset and the deception dataset demonstrate that both the proposed CoSpa algorithms outperform the traditional SVM with lexical terms and PCFG rules in spam review identification. Moreover, the CoSpa-U strategy outperforms the CoSpa-C strategy when we use the absolute value of decision function of SVM as the confidence.

  10. A case study of small hydro and grid extension for rural electrification alternatives and complementarities

    International Nuclear Information System (INIS)

    Tebicke, H.L.; Mariam, H.G.

    1990-01-01

    This paper reports that rural electrification in Eastern and Southern African Countries (ESAC) has so far been based largely on stand-alone diesel electric generating plant or on the extension of high-voltage transmission grids fed by large hydro and/or thermal electric generating stations. The alternative of furnishing supply at modest investment and competitive cost from a nearby small- hydro plant has rarely been considered in those countries of the sub-region that have ample hydro-power resources. All countries in the sub-region (except Angola) import petroleum and/or petroleum product supplies, as well as all hardware for electricity supply and utilization. As a result, in most countries an acute shortage of foreign exchange severely hampers implementation of rural electrification schemes. This should turn attention increasingly to strategies which are less capital-intensive and less dependent on foreign exchange, such as small-hydro plants, where the resource is located near to rural demand. Increasing the local content of small-hydro project implementation has paid off in recent years, considerably reducing costs in a number of Asian and Latin American projects. Local contributions have taken the form of resource assessment at a particular site, design, construction works, and fabrication of relatively simple components of power plant such as hydraulic equipment, low pressure penstocks and gates, as well as simpler types of turbines (e.g., the Banki type). Inadequacy of indigenous technical capacity to make similar local contributions in the ESAC has meant that the few recent small-hydro projects have relied on importing both expertise and equipment. The high costs resulting have frequently fueled arguments against pursuit of small-hydro projects

    2014-12-01

    spa typing of methicillin-resistant Staphylococcus aureus (MRSA) has traditionally been done by PCR amplification and Sanger sequencing of the spa repeat region. At Hvidovre Hospital, Denmark, whole-genome sequencing (WGS) of all MRSA isolates has been performed routinely since January 2013, and an in-house analysis pipeline determines the spa types. Due to national surveillance, all MRSA isolates are sent to Statens Serum Institut, where the spa type is determined by PCR and Sanger sequencing. The purpose of this study was to evaluate the reliability of the spa types obtained by 150-bp paired-end Illumina WGS. MRSA isolates from new MRSA patients in 2013 (n = 699) in the capital region of Denmark were included. We found a 97% agreement between spa types obtained by the two methods. All isolates achieved a spa type by both methods. Nineteen isolates differed in spa types by the two methods, in most cases due to the lack of 24-bp repeats in the whole-genome-sequenced isolates. These related but incorrect spa types should have no consequence in outbreak investigations, since all epidemiologically linked isolates, regardless of spa type, will be included in the single nucleotide polymorphism (SNP) analysis. This will reveal the close relatedness of the spa types. In conclusion, our data show that WGS is a reliable method to determine the spa type of MRSA.

    2009-01-01

    Full Text Available Introduction. Ankylosing spondilitis (AS is a disease from a group of seronegative spondyloarthropathies with the prevalence of 0.1% affecting mainly young males, which also gives sociomedical significance to the disease. Among all inflammatory arthropathies, AS is the most suitable for balneotherapy. Thermomineral water of the Niška Banja spa is homeothermic, oligomineral, alkaline, low radioactive radon water and also, in conjunction with mineral peloid, is considered to be optimal for this indication. Objective. Our aim was to investigate the effects of natural factors of the Niška Banja spa as a part of complex treatment on the indexes of mobility of the vertebral column in the patients with AS. Methods. The study enrolled 40 patients with the average age of 48.0±14.82 years and the average duration of disease of 16.9±6.42 years. Patients were treated with hydro- and peloid- otherapy during the average of 17.23±2.71 days. At the beginning and at the end of treatment, a number of indexes of spinal mobility were measured. The statistical significance of differences was calculated using the Student's t-test. Results. All of the measured indexes were better after balneotherapy reaching statistically significant differences in regard to the wall-to-occiput distance (p<0.05, the index of sagittal mobility of the cervical (p<0.05 and lumbar (p<0.005 spine. Conclusion. The application of natural factors of the Niška Banja spa during complex treatment of the patients with AS is accompanied with the objective increase of the spine mobility.

    Very few studies tested the effectiveness of spa therapy in older patients with osteoarthritis. Therefore, we aimed to evaluate the short-term effects of spa therapy in patients aged 65 years and older with generalized, knee, hip, and cervical and lumbar spine osteoarthritis. In an observational retrospective study design at the Medical Ecology and Hydroclimatology Department of Istanbul Medical Faculty, we analyzed the records of 239 patients aged over 65 years with the diagnosis of all types of osteoarthritis who were prescribed a spa therapy course in some spa resorts in Turkey between 7 March 2002 and 31 December 2012. They travelled to a spa resort where they stayed at a thermal spa hotel and followed the usual therapy packages for 2 weeks. Patients were assessed by an experienced physician within a week before the spa journey and within a week after the completion of the spa therapy. Compared with baseline in whole sample, statistically significant improvements were observed in pain (visual analog scale, VAS), patient and physician global assessments (VAS), Health Assessment Questionnaire disability index (HAQ-DI), Lequesne algofunctional index (LAFI) for knee, Western Ontario and McMaster Universities index (WOMAC), Waddell disability index (WDI), and Neck Pain and Disability Scale (NPAD). According to Outcome Measures in Rheumatology—Osteoarthritis Research Society International (OMERACT-OARSI) Set of Responder Criteria, responder rate were 63.8 % (51/80) in generalized, 52 % (13/25) in knee, 50 % (2/4) in hip, 66.7 % (8/12) in lumbar, and 100 % (6/6) in cervical osteoarthritis subgroups. Spa therapy improved pain and physical functional status in older patients with osteoarthritis, especially generalized osteoarthritis and multiple joint osteoarthritis with involvement of knee. This improvement was clinically important in majority of the patients. To confirm the results of this preliminary study, there is a need of a randomized controlled clinical study

    Turkey has a lot of thermal and mineral springs and is looking back on a still vivid tradition of spa therapy and balneotherapy, applied especially for the treatment of rheumatic diseases. This tradition is predominantly empiric and intuitive, however, it has assumed some important aspects of modern balneotherapeutic methods as well. This article is aimed at presenting the characteristics of traditional and modern balneological and spa therapy forms in Turkey. The studies which have been conducted between 1990 and 2000 in different spas in Turkey on the efficacy and effectiveness of spa therapy and balneotherapy for rheumatic diseases have been searched and analyzed independent of their design. A descriptive evaluation of the studies was carried out. A total of 15 published studies have been found and analyzed. The investigations have been carried out in 8 different spa resorts in Turkey. In these studies the effectiveness and efficacy of different balneological and spa therapies on a variety of rheumatic diseases (from osteoarthritis to fibromyalgia and from rheumatoid arthritis to low back pain) could be shown. Nearly all studied balneotherapeutic modalities were applied as bathing cures. Only in one study peloid therapy was applied. Balneotherapeutic therapy was applied in a modern and traditional way, and both open and stationary spa therapy forms were used at the same time. The review has shown the effectiveness of the investigated spa therapy and balneotherapy forms. It could be concluded that nearly all forms of spa therapy and balneotherapy used for the treatment of rheumatic diseases in Turkey are effective. A definitive conclusion, however, is not possible because of the heterogeneity of the study designs, methodological flaws, and the publication bias. In future good quality randomized controlled trials are needed. Copyright 2004 S. Karger GmbH, Freiburg

    The 'Elguea' spa, located in the north coast of the county of Villa Clara, Cuba, is considered one of those more important spas of Latin America. The waters of this spa are rich in salts of chlorine, sodium, bromine, sulfides and its contain radon. As a result of measurements of environmental gamma dose rates carried out in the area of the spa, its were considered levels of dose between 0.13 and 2.3 mSv. The obtained results motivated that it was carried out a characterization, from the radiological point of view, of the spa. This characterization is of supreme importance to be able to evaluate the impact that it has and the discharges of its waters on the environment, as well as, those dose that the population potentially affected can receive by these discharges. With this end its were carried out quantitative determinations of those existent natural more significant radionuclides in different environmental objects coming from the area of the spa and its surroundings, as well as one characterization gamma 'in situ' of the same one. The obtained results are present in this work. (Author)

    The 12th of July 1635, Jan van Beverwyck wrote a letter from Dordrecht to his esteemed friend Luis Nunez, in Antwerp. He asked him for indications about the cure of kidney stones of which he was suffering. He had just passed two calculi very painfully. Nunez answered on July 31. His letter summarized his own experience with this disease. In such cases, temperate diuretics and emollients are well indicated: ingestion of light decoctions of Malva and Viola, Caerefolium and Parieteria as well as Marshmallow syrup. No purge and no 'chemicals'. However, the best remedy was drinking Spa water. Usually the best way to absorb it is to come to the springs, in the Ardennes, part of the independent Principality of Liège. However, considering the horrors of the war (the Thirty Years War) endangering the country, van Beverwyck would be wise to drink imported water during 40 or 50 days, while staying home quietly, in Dordrecht. The letter points out the importance of provoked diuresis in the treatment of kidney stones. On the other hand the letter is an illustration of the continuing contacts between the United Provinces and the Spanish territories and of the commercial traffic between Antwerp, Dordrecht and Spa. The exported water was bottled from many 'pouhons'. It was acid, ferruginous, sulfurous and saturated with carbon dioxide; no pathogen germs, at least at the spring. Nunez quoted the large number of his patients cured with Spa water in Antwerp. This is an illustration of its commercial expansion even during this critical period.

    Molecular typing is an important tool for control and prevention of infection. A suitable molecular typing method for epidemiological investigation must be easy to perform, highly reproducible, inexpensive, rapid and easy to interpret. In this study, two molecular typing methods including the conventional PCR-sequencing method and high resolution melting (HRM) analysis were used for staphylococcal protein A (spa) typing of 30 Methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered from clinical samples. Based on PCR-sequencing method results, 16 different spa types were identified among the 30 MRSA isolates. Among the 16 different spa types, 14 spa types separated by HRM method. Two spa types including t4718 and t2894 were not separated from each other. According to our results, spa typing based on HRM analysis method is very rapid, easy to perform and cost-effective, but this method must be standardized for different regions, spa types, and real-time machinery.

    We investigated the immune camouflage effects of methoxy polyethylene glycol succinimidyl propionate (mPEG-SPA) on corneal antigens and explored a novel approach for reducing corneal antigenicity, thereby decreasing corneal graft rejection. Importantly, this approach did not alter normal local immunity. Corneal grafts were treated with mPEG-SPA 5KD or 20KD (3% W/V), which could shield major histocompatibility antigen class I molecules (RT1-A) of corneal grafts. Skin grafts of Wistar rats were transplanted to SD rats. Then the splenic lymphocytes were isolated from SD rats. Subsequently, the lymphocytes were co-cultured with autologous corneal grafts or untreated corneal grafts and PEGylated grafts treated with mPEG-SPA 5KD or 20KD obtained from the counterpart skin donors, which were used as autologous control, allogeneic control, mPEG-SPA 5KD group and mPEG-SPA 20KD group, respectively. Lymphocyte proliferation was lower in mPEG-SPA 5KD group and mPEG-SPA 20KD group than in the allogeneic control. SD rats with corneal neovascularisation were used as recipients for high-risk corneal transplantation and were randomly divided into four groups: autologous control, allogeneic control, mPEG-SPA 5KD group and mPEG-SPA 20KD group. The recipients received corneal grafts from Wistar rats. Corneal graft survival was prolonged and graft rejection was reduced in the mPEG-SPA 5KD group and the mPEG-SPA 20KD group compared to the allogeneic control. Thus, we think that mPEG-SPA could immunologically camouflage corneal antigens to prolong corneal grafts survival in high-risk transplantation. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Objective To determine whether spa therapy, plus home exercises and usual medical treatment provides any benefit over exercises and usual treatment, in the management of knee osteoarthritis. Methods Large multicentre randomised prospective clinical trial of patients with knee osteoarthritis according to the American College of Rheumatology criteria, attending French spa resorts as outpatients between June 2006 and April 2007. Zelen randomisation was used so patients were ignorant of the other group and spa personnel were not told which patients were participating. The main endpoint criteria were patient self-assessed. All patients continued usual treatments and performed daily standardised home exercises. The spa therapy group also received 18 days of spa therapy (massages, showers, mud and pool sessions). Main Endpoint The number of patients achieving minimal clinically important improvement (MCII) at 6 months, defined as ≥19.9 mm on the visual analogue pain scale and/or ≥9.1 points in a normalised Western Ontario and McMaster Universities osteoarthritis index function score and no knee surgery. Results The intention to treat analysis included 187 controls and 195 spa therapy patients. At 6 months, 99/195 (50.8%) spa group patients had MCII and 68/187 (36.4%) controls (χ2=8.05; df=1; p=0.005). However, no improvement in quality of life (Short Form 36) or patient acceptable symptom state was observed at 6 months. Conclusion For patients with knee osteoarthritis a 3-week course of spa therapy together with home exercises and usual pharmacological treatments offers benefit after 6 months compared with exercises and usual treatment alone, and is well tolerated.

    This study was conducted in the scope of IAEA project with the name 'Establishing a Systematic Radioactivity Survey and Total Effective Dose Assessment in Natural Balneological Sites' (TUR/9/018), at the Health Physics department of Saraykoey Nuclear Research and Training Center (SANAEM). The aim of this study is estimation of radon and progeny sourced effective dose for the people who are working at the spa facilities by measuring radon activity concentration (RAC) at the ambient air of indoor spa pools and dressing rooms. As it is known, the source of the radon gas is the radium content of the earth crust. Therefore, thermal waters coming from ground may contain dissolved radon and the radon can diffuse water to air. So the ambient air of spa pools can contain serious RAC that depends on a lot of parameters. In this regard, RAC measurements were executed at the 70 spa facilities in Turkey. The measurements were done with both active and passive methods at ambient air of spa pools and dressing rooms. Thus, active measurements were carried out by using the Alphaguard R with diffusion mode during half an hour, and passive measurements were carried out by using the humidity resistive CR-39 radon detectors during 2 months. Results show that RAC values at ambient air of spa pools varies between 13 Bq m -3 and 10 kBq m -3 . Because long-term measurements are more reliable, if it is available, for dose calculations passive radon measurements (with CR-39 detectors) at ambient air of spa pools and dressing rooms were used, otherwise active measurement results were used. With the measurement by the conversion coefficients of ICRP 65 and occupational data of the employees has got from questionnaire forms, effective dose values were calculated. According to the calculations, spa employees are exposed to annual average dose between 0.05 and 29 mSv because of radon and progeny. (authors)

  7. Unbalance influence on the rotating assembly dynamics of a hydro

    The dynamics of the rotating parts of a hydro is characterized by the dynamic interaction between the rotor, the stator and the working fluid in order to operate the hydro. The main factors influencing the dynamics of the rotating parts of a hydro are: rotor unbalance, unbalanced magnetic pull, shaft misalignment and hydraulic flow regime. Rotor unbalanced is one of the most common factors influencing the dynamic stability of the rotating parts of a hydro. The unbalanced is determined by: uneven distribution of rotating masses, displacement of parts in the rotor during rotation, inhomogeneity of rotor component materials, expansion of the rotor due to heating, and rising speed during the transient discharge of the load. The mechanical imbalance of a rotor can lead to important forces, responsible for the vibration of the machine, which ultimately leads to a shorter operating time. Even a low unbalance can lead, in the case of high speed machines, to major unbalance forces that cause significant damage to the equipment. The unbalance forces cause additional vibrations in the bearings as well as in the foundation plate. To avoid these vibrations, it is necessary in the first stage to balance the static rotor in the construction plant and then to a dynamic rotation balancing.

    Osteoarthritis (OA) continues to be one of the leading causes of `years lived with disability' worldwide. Symptomatic knee OA is highly prevalent among people aged 50 years and over and is destined to become an ever more important healthcare problem. Current management of knee OA includes non-pharmacological and pharmacological treatments. Spa therapy is one of the most commonly used non-pharmacological approaches for OA in many European countries, as well as in Japan and Israel. Despite its long history and popularity, spa treatment is still the subject of debate and its role in modern medicine continues to be unclear. The objective of this review is to summarize the currently available information on clinical effects and mechanisms of action of spa therapy in knee OA. Various randomized controlled clinical trials (RCTs) were conducted to assess the efficacy and tolerability of balneotherapy and mud-pack therapy in patients with knee OA. Data from these clinical trials support a beneficial effect of spa therapy on pain, function and quality of life in knee OA that lasts over time, until 6-9 months after the treatment. The mechanisms by which immersion in mineral or thermal water or the application of mud alleviate suffering in OA are not fully understood. The net benefit is probably the result of a combination of factors, among which the mechanical, thermal and chemical effects are most prominent. In conclusion, spa therapy seems to have a role in the treatment of knee OA. Additional RCTs and further studies of mechanisms of action with high methodological quality are necessary to prove the effects of spa therapy.

    The lung provides the main route for nanomaterial exposure. Surfactant protein A (SP-A) is an important respiratory innate immune molecule with the ability to bind or opsonise pathogens to enhance phagocytic removal from the airways. We hypothesised that SP-A, like surfactant protein D, may interact with inhaled nanoparticulates, and that this interaction will be affected by nanoparticle (NP) surface characteristics. In this study, we characterise the interaction of SP-A with unmodified (U-PS) and amine-modified (A-PS) polystyrene particles of varying size and zeta potential using dynamic light scatter analysis. SP-A associated with both 100 nm U-PS and A-PS in a calcium-independent manner. SP-A induced significant calcium-dependent agglomeration of 100 nm U-PS NPs but resulted in calcium-independent inhibition of A-PS self agglomeration. SP-A enhanced uptake of 100 nm U-PS into macrophage-like RAW264.7 cells in a dose-dependent manner but in contrast inhibited A-PS uptake. Reduced association of A-PS particles in RAW264.7 cells following pre-incubation of SP-A was also observed with coherent anti-Stokes Raman spectroscopy. Consistent with these findings, alveolar macrophages (AMs) from SP-A(-/-) mice were more efficient at uptake of 100 nm A-PS compared with wild type C57Bl/6 macrophages. No difference in uptake was observed with 500 nm U-PS or A-PS particles. Pre-incubation with SP-A resulted in a significant decrease in uptake of 100 nm A-PS in macrophages isolated from both groups of mice. In contrast, increased uptake by AMs of U-PS was observed after pre-incubation with SP-A. Thus we have demonstrated that SP-A promotes uptake of non-toxic U-PS particles but inhibits the clearance of potentially toxic A-PS particles by blocking uptake into macrophages.

    This study aims to investigate whether 2-week spa therapy, as an adjunct to usual pharmacological therapy, has any beneficial effect in patients with rheumatoid arthritis (RA). In this single-blind crossover study, 50 patients were randomly assigned in a 1:1 manner to receive usual pharmacological therapy plus 2-week spa therapy or usual pharmacological therapy alone (period 1.6 months); after a 9-month washout, patients were crossed over to the opposite assignment (period 2.6 months). Spa therapy program included a daily saline balneotherapy session at 36-37 °C for 20 min except Sundays. The clinical outcomes were evaluated at baseline, after spa therapy (2 weeks) and 3 and 6 months after the spa therapy in both period and were pain (Visual Analogue Scale (VAS)), patient and physician global assessments (VAS), Health Assessment Questionnaire (HAQ), and Disease Activity Score (DAS28). Spa therapy was superior to control therapy in improving all the assessed clinical outcomes at the end of the spa therapy. This superiority persisted significantly in physician global assessment ( p = 0.010) and with a trend in favor of spa group in patient global assessment ( p = 0.058), function ( p = 0.092), and disease activity ( p = 0.098) at 3 months. Statistically significant improvements were found in spa therapy compared to control in disease activity ( p = 0.006) and patient ( p = 0.020) and physician global ( p = 0.011) assessments, and a trend toward improvements in pain ( p = 0.069) and swollen joints ( p = 0.070) at 6 months. A 2-week spa therapy adjunct to usual pharmacological therapy provided beneficial clinical effects compared to usual pharmacological therapy alone, in RA patients treated with traditional disease-modifying antirheumatic drugs. These beneficial effects may last for 6 months.

    Aim. To perform a narrative review of spa therapy for management of the fibromyalgia syndrome (FMS), evaluating this traditional time-honored form of therapy in a historical perspective. Methods. Medline was searched using the terms “Spa therapy,” “Balneotherapy,” and “Fibromyalgia” between 1990 (year of ACR fibromyalgia criteria publication) and April 2013. The Cochrane database was also searched. Publications relating to the implementation of spa therapy and related practices over the centuries were identified through references, searched, and reviewed. Results. Reports of balneotherapy were described from diverse locations throughout Europe and Asia, and various forms of water-related therapy have been incorporated for many musculoskeletal indications. In the management of FMS, spa therapy has generally been shown to be well accepted and moderately effective for symptom reduction. Conclusion. While achieving high-quality evidence-based conclusions is difficult for complex natural therapies such as spa therapy, the existing evidence indicates a positive effect in management of FMS. In view of the long history of this modality in the management of rheumatic pain as well as the inherent difficulties related to pharmacological treatment, the role of spa therapy should currently be recognized as part of a therapeutic program for FMS.

  13. Role of surfactant protein A (SP-A)/lipid interactions for SP-A functions in the lung.

    Casals, C

    2001-01-01

    Surfactant protein A (SP-A), an oligomeric glycoprotein, is a member of a group of proteins named collectins that contain collagen-like and Ca(2+)-dependent carbohydrate recognition domains. SP-A interacts with a broad range of amphipathic lipids (glycerophospholipids, sphingophospholipids, glycosphingolipids, lipid A, and lipoglycans) that are present in surfactant or microbial membranes. This review summarizes SP-A/lipid interaction studies regarding the lipid system used (i.e., phospholipid vesicles, phospholipid monolayers, and lipids immobilized on silica or adsorbed on a solid support). The effect of calcium, ionic strength, and pH on the binding of SP-A to lipids and the subsequent lipid aggregation process is discussed. Current evidence suggests that hydrophobic-binding forces are involved in the peripherical association of SP-A to membranes. It is also proposed that fluid and liquid-ordered phase coexistence in surfactant membranes might favor partition of SP-A into those membranes. The binding of SP-A to surfactant membranes containing hydrophobic surfactant peptides makes possible the formation of a membrane reservoir in the alveolar fluid that is protected by SP-A against inactivation and improves the rate of surfactant film formation. In addition, the interaction of SP-A with membranes might enhance the affinity of SP-A for terminal carbohydrates of glycolipids or glycoproteins on the surface of invading microorganisms.

    A discussion of the potential privatisation of Hydro-Quebec, and of the motivation to do so, was presented. The creation of Hydro-Quebec resulted from the nationalization in 1963 of all major electricity producers in the province of Quebec. Since its inception, Hydro-Quebec has gone through many episodes of restructuring but none more far reaching in extent, or in consequences, than the present one. The current deregulation of the electrical industry in Quebec, and the potential commercialization of Hydro-Quebec is considered to be a natural and inevitable result of the current global trend towards competition in the power industry and the demand for greater consumer choice. 1 tab

    Shigella rely entirely on the action of a single type three secretion system (T3SS) to support cellular invasion of colonic epithelial cells and to circumvent host immune responses. The ATPase Spa47 resides at the base of the Shigella needle-like type three secretion apparatus (T3SA), supporting protein secretion through the apparatus and providing a likely means for native virulence regulation by Shigella and a much needed target for non-antibiotic therapeutics to treat Shigella infections. Here, we show that MxiN is a differential regulator of Spa47 and that its regulatory impact is determined by the oligomeric state of the Spa47 ATPase, with which it interacts. In vitro and in vivo characterization shows that interaction of MxiN with Spa47 requires the six N-terminal residues of Spa47 that are also necessary for stable Spa47 oligomer formation and activation. This interaction with MxiN negatively influences the activity of Spa47 oligomers while upregulating the ATPase activity of monomeric Spa47. Detailed kinetic analyses of monomeric and oligomeric Spa47 in the presence and absence of MxiN uncover additional mechanistic insights into the regulation of Spa47 by MxiN, suggesting that the MxiN/Spa47 species resulting from interaction with monomeric and oligomeric Spa47 are functionally distinct and that both could be involved in Shigella T3SS regulation. Uncovering regulation of Spa47 by MxiN addresses an important gap in the current understanding of how Shigella controls T3SA activity and provides the first description of differential T3SS ATPase regulation by a native T3SS protein.

    Very little is known about how the spa gene mutates over time in methicillin-resistant Staphylococcus aureus (MRSA) from the same patient. Copenhagen is an area with low prevalence of MRSA but with high variability in spa types. We collected 1536 MRSA isolates from 319 patients during a 5-year...... period and found spa type alterations in 30 MRSA isolates (2%) from 13 patients (4%). The alteration most often seen was the deletion of repeats followed by repeat duplication and point mutation....

  20. Ontario Hydro's nuclear program

    1984-01-01

    This report briefly describes Ontario Hydro's nuclear program, examining the design and construction status, and the future from Ontario Hydro's perspective. Ontario Hydro relies heavily on nuclear power. Nuclear fuel was responsible for approximately 34% of Ontario Hydro's energy production in 1983. The nuclear proportion was supplied by twelve operating units located: NPD, Douglas Point, Pickering A and B. It is expected that by approximately 1992, 65% of the total energy needs will be generated through nuclear power

    Millions are exposed to ozone levels above recommended limits, impairing lung function, causing epithelial damage and inflammation, and predisposing some individuals to pneumonia, asthma, and other lung conditions. Surfactant protein-A (SP-A) plays a role in host defense, the regulation of inflammation, and repair of tissue damage. We tested the hypothesis that the lungs of SP-A(-/-) (KO) mice are more susceptible to ozone-induced damage. We compared the effects of ozone on KO and wild type (WT) mice on the C57BL/6 genetic background by exposing them to 2 parts/million of ozone for 3 or 6 h and sacrificing them 0, 4, and 24 h later. Lungs were subject to bronchoalveolar lavage (BAL) or used to measure endpoints of oxidative stress and inflammation. Despite more total protein in BAL of KO mice after a 3 h ozone exposure, WT mice had increased oxidation of protein and had oxidized SP-A dimers. In KO mice there was epithelial damage as assessed by increased LDH activity and there was increased phospholipid content. In WT mice there were more BAL PMNs and elevated macrophage inflammatory protein (MIP)-2 and monocyte chemoattractant protein (MCP)-1. Changes in MIP-2 and MCP-1 were observed in both KO and WT, however mRNA levels differed. In KO mice MIP-2 mRNA levels changed little with ozone, but in WT levels they were significantly increased. In summary, several aspects of the inflammatory response differ between WT and KO mice. These in vivo findings appear to implicate SP-A in regulating inflammation and limiting epithelial damage in response to ozone exposure

    2011-01-01

    Background and purpose: The HydroCoil Embolic System (HES) was developed to reduce recurrences of aneurysms relative to platinum coils. But the HydroCoil Embolic System was characterized with many limitations. The manufacturer had recognized the challenge and recently a new design of hydrogel-coated coil-HydroSoft has become available in the market as the new generation HydroCoil. We reported our initial experience using HydroSoft coil versus HydroCoil in our center. Methods: 75 aneurysms embolized primarily using HydroSoft Coils from July 2008 to May 2009 were compared with 66 volume- and shape-matched aneurysms treated with HydroCoils from March 2006 to August 2008. Outcome measures included length and number of coils used, contrast volume, and length of hospital stay. During embolization, a stable framework was first established with bare coils, and hydrogel-coated coils were used subsequently to increase the packing density. Follow-up angiographic results 6 months after treatment were evaluated among some of the patients. Results: Successful coil embolization was achieved in all patients. There were no differences in average total coil length used per aneurysm. There were no differences in length of hospital stay and packing density. HydroSoft coils were more suitable using as the finishing or final coil. HydroSoft coil decreased the procedure-related retreated rates, and aneurysm packing was finished with soft, flexible HydroSoft coil and decreased the neck remnant rates. Follow-up angiography in HydroSoft-treated patients at 6 months revealed aneurysm stability without significant residual neck. Conclusions: HydroSoft coil allowed us to deploy coated coils with good packing density. A slight expansion of these coils at the neck can be expected to reduce neck remnant and potentially inhibit recurrence.

    Gram-negative pathogens often use conserved type three secretion systems (T3SS) for virulence. The Shigella type three secretion apparatus (T3SA) penetrates the host cell membrane and provides a unidirectional conduit for injection of effectors into host cells. The protein Spa47 localizes to the base of the apparatus and is speculated to be an ATPase that provides the energy for T3SA formation and secretion. Here, we developed an expression and purification protocol, producing active Spa47 and providing the first direct evidence that Spa47 is a bona fide ATPase. Additionally, size exclusion chromatography and analytical ultracentrifugation identified multiple oligomeric species of Spa47 with the largest greater than 8 fold more active for ATP hydrolysis than the monomer. An ATPase inactive Spa47 point mutant was then engineered by targeting a conserved Lysine within the predicted Walker A motif of Spa47. Interestingly, the mutant maintained a similar oligomerization pattern as active Spa47, but was unable to restore invasion phenotype when used to complement a spa47 null S. flexneri strain. Together, these results identify Spa47 as a Shigella T3SS ATPase and suggest that its activity is linked to oligomerization, perhaps as a regulatory mechanism as seen in some related pathogens. Additionally, Spa47 catalyzed ATP hydrolysis appears to be essential for host cell invasion, providing a strong platform for additional studies dissecting its role in virulence and providing an attractive target for anti-infective agents. © 2016 The Protein Society.

    Highlights: • This paper presents a novel 3 three-bladed vertical-axis micro-hydro turbine system. • This paper presents structure and performance of micro-hydroelectric turbine system. • The paper reveal that using VAMHT system in water is distinct from using in wind. • This paper present an experimental results of VAMHT system. • The paper show that the status transformation from cut-into stable power generation is short. - Abstract: This paper presents a novel 3-kW three-bladed vertical-axis micro-hydro turbine (VAMHT) system. The experimental results reveal that using this type of turbine in water is distinct from using it in wind. The micro-hydro turbine system uses a three-phase permanent magnet symmetric generator that transforms mechanical energy into electrical energy. The output voltage and frequency of the generator depend on water flow speed, and voltage steady equipment is used to maintain the maximum output power of the DC bus. According to the maximum power point tracking of the micro-hydro turbine system, the condition monitoring of the novel micro-hydro turbine requires no water flow meter. Furthermore, the construction and installation of the new micro-hydro turbine is simple, economical, and stable. This system combines a micro-hydro generator and electrical state-monitoring system, which can measure the speed, output power, DC-bus voltage, and all electrical characteristics of the micro-hydro turbine system. The results of comparing turbine between wind and water show that the speed ranges of water flow is narrower than that of wind, and the status transformation from cut-into stable power generation is short

  8. From sulphur to perfume: spa and SPA at Monchique, Algarve.

    Science.gov (United States)

    Bastos, Cristiana

    2011-04-01

    In the thermal village of Monchique, Algarve, different streams of water-related knowledge and practices coexisted for centuries. Those waters were traditionally known as aguas santas (holy waters) and believed to have redemptive healing powers. In the seventeenth century, the Catholic church took control of the place, refashioned the bathing rituals, developed infrastructures and provided assistance to the patients, granting free treatment to the poor. In the nineteenth century, the state replaced the church and imposed that treatments should be provided by professionals trained in the scientific principles of medical hydrology. Secular and scientific as they were, clinical logbooks still allowed for the account of patients that embodied miracle-like redemptive cures 'at the third bath'. People went to Monchique both for its magic and its medicine, bringing in the body ailments achieved in their lives of hard labour. They also went there for a socialising break while healing. From mendicants to rich landowners, coming mostly from the Algarve and neighbouring Alentejo, they crowded the place in summertime. In the twentieth century, as in other places in continental Europe, the spa evolved into a highly medicalised place that qualified for medical expenses reimbursements, which implied the eclipsing--at least from representation--of its leisure component. In the twenty-first century, a new trend of consumer-centred, market-based, post-water balneology with an emphasis on wellness and leisure reinvented the spa as place for lush and diversified consumption. This article argues that the seemingly contradictory systems (markets and medicine) coexist much in the same way that magic, religion and medicine coexisted in the old water sites. The new SPAs, rather than putting an end to the old spas, have enabled them to survive by reinventing thermal sites as places of attraction and leisure.

    Adhesin-mediated bacterial interspecies interactions are important elements in oral biofilm formation. They often occur on a species-specific level, which could determine health or disease association of a biofilm community. Among the key players involved in these processes are the ubiquitous fusobacteria that have been recognized for their ability to interact with numerous different binding partners. Fusobacterial interactions with Streptococcus mutans, an important oral cariogenic pathogen, have previously been described but most studies focused on binding to non-mutans streptococci and specific cognate adhesin pairs remain to be identified. Here, we demonstrated differential binding of oral fusobacteria to S. mutans. Screening of existing mutant derivatives indicated SpaP as the major S. mutans adhesin specific for binding to Fusobacterium nucleatum ssp. polymorphum but none of the other oral fusobacteria tested. We inactivated RadD, a known adhesin of F. nucleatum ssp. nucleatum for interaction with a number of gram-positive species, in F. nucleatum ssp. polymorphum and used a Lactococcus lactis heterologous SpaP expression system to demonstrate SpaP interaction with RadD of F. nucleatum ssp. polymorphum. This is a novel function for SpaP, which has mainly been characterized as an adhesin for binding to host proteins including salivary glycoproteins. In conclusion, we describe an additional role for SpaP as adhesin in interspecies adherence with RadD-SpaP as the interacting adhesin pair for binding between S. mutans and F. nucleatum ssp. polymorphum. Furthermore, S. mutans attachment to oral fusobacteria appears to involve species- and subspecies-dependent adhesin interactions. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  15. Fibromyalgia Syndrome and Spa Therapy: Myth or Reality?

    2012-01-01

    Full Text Available Fibromyalgia syndrome (FS is a common musculoskeletal disorder characterized by otherwise unexplained chronic widespread pain, a lowered pain threshold, high tender point counts, sleep disturbances, fatigue, headache, irritable bowel syndrome, morning stiffness, paraesthesias in the extremities, often psychological distress and depressed mood. Consequently, FS has a negative impact on working capacity, family life, social functioning and quality of life. Because of unknown etiology and not clearly understood pathogenesis, there is no standard therapy regime for FS. A variety of medical treatments, including antidepressants, opioids, analgesic or non-steroidal anti-inflammatory drugs, sedatives, muscle relaxants and antiepileptics, have been used to treat FS. Currently, no pharmacological treatment for FS is consistently successful. According to recent guidelines, the optimal treatment of FS requires a multidisciplinary approach with a combination of non-pharmacological and pharmacological treatment modalities. Spa therapy is a popular treatment for FS in many European countries, as well as in Japan and Israel. However, despite their long history and popularity spa treatments are still the subject of debate and their role in modern medicine is still not clear. The objective of this review is to summarize the currently available information on clinical effects and mechanism of action of spa therapy in FS. We also provide some suggestions for further development in this area.

  17. A comparison of the aquatic impacts of large hydro and small hydro projects

    Science.gov (United States)

    Taylor, Lara A.

    The expansion of small hydro development in British Columbia has raised concerns surrounding the effects of these projects, and the provincial government's decision to proceed with Site C has brought attention to the impacts of large hydro. Together, these decisions highlight that there are impacts associated with all energy development. My study examines the aquatic effects of large and small hydro projects using two case study sites: Site C and the Upper Harrison Water Power Project. I first determine the aquatic effects of each of the case study sites. Next, I use existing literature and benefits transfer to determine the monetary value of these effects. My results suggest that, with mitigation, small hydro projects have less of an effect on the environment than a large hydro project per unit of electricity. I also describe the implications of my study in the context of current British Columbia energy policy. Keywords: hydropower; aquatic effects. Subject Terms: environmental impact assessment; benefits transfer.

    Long-term power system expansion planning studies are carried out to meet the electricity requirement in the future. Prior to the expansion planning studies, it is essential to know the energy potential of the existing generating system, especially the hydro power plants. Detailed hydro thermal stimulation studies of the integrated system is therefore carried out to determine the best way to maximise the hydro energy of the existing and committed plants. The results of the integrated system simulated model are stored in numerous files and are available for retrieval. Most important output used for expansion analysis is the energy production of each hydro plant. The annual hydro energy potential of the total hydro system of Sri Lanka for the hydrological year from 1949 to 1988 is given. Hydro condition data with different probability levels are also indicated

    High-precision analyses of supersymmetry parameters aim at reconstructing the fundamental supersymmetric theory and its breaking mechanism. A well defined theoretical framework is needed when higher-order corrections are included. We propose such a scheme, Supersymmetry Parameter Analysis SPA, based on a consistent set of conventions and input parameters. A repository for computer programs is provided which connect parameters in different schemes and relate the Lagrangian parameters to physical observables at LHC and high energy e+e- linear collider experiments, i.e., masses, mixings, decay widths and production cross sections for supersymmetric particles. In addition, programs for calculating high-precision low energy observables, the density of cold dark matter (CDM) in the universe as well as the cross sections for CDM search experiments are included. The SPA scheme still requires extended efforts on both the theoretical and experimental side before data can be evaluated in the future at the level of the d...

    Hydro power on account of its several inherent advantages has a key role to play in the development of long term energy strategies based on diversified and balance use of natural national resources. Our country is fortunate to be endowed with large hydro-electric potential. It is estimated that the hydro potential while fully developed may yield to an installed capacity of 1,50,000 MW. An attempt has been made in this paper to examine and analyse the status and trend of hydro power development, need for accelerated development of hydro power, myths about hydro electric projects, principal causes responsible for scaling down of hydro share in the total installed capacity and strategies which could restore optimum hydro thermal mix.

    2014-09-01

    Full Text Available In wireless sensor networks, the energy consumption is mainly occurred in the stage of information transmission. The Low Density Parity Check code can make full use of the channel information to save energy. Because of the widely used decoding algorithm of the Low Density Parity Check code, this paper proposes a new decoding algorithm which is based on the LLR-SPA (Sum-Product Algorithm in Log-Likelihood-domain to improve the accuracy of the decoding algorithm. In the modified algorithm, a piecewise linear function is used to approximate the complicated Jacobi correction term in LLR-SPA decoding algorithm. Construct the tangent by the tangency point to the function of Jacobi correction term, which is based on the first order Taylor Series. In this way, the proposed piecewise linear approximation offers almost a perfect match to the function of Jacobi correction term. Meanwhile, the proposed piecewise linear approximation could avoid the operation of logarithmic which is more suitable for practical application. The simulation results show that the proposed algorithm could improve the decoding accuracy greatly without noticeable variation of the computational complexity.

    The present study was undertaken to determine the distribution and genotypic characteristics of Staphylococcus aureus isolates recovered from naturally occurring mastitis in cattle and buffaloes. For this purpose a total of 1445 lactating cattle (653) and buffaloes (792) present at two experimental livestock farms Okara (Bahadarnagar) and Sahiwal (Qadiarabad), in and around district Faisalabad and slaughtered at an abattoir due to low milk yield and were screened for mastitis. California Mastitis Test (CMT) was used to detect sub clinical mastitis. The positive quarter milk samples were collected for culturing of S. aureus isolates. taphylococcus aureus isolates were identified on the basis of growth features, biochemical characteristics, coagulase test and as well as amplification of coagulase (coa) and spa (spa-X) genes specific to its virulence. S. aureus isolates (n=265) were characterized by Polymerase chain reaction to determine the frequency of coagulase (coa) and spa (spa-X) genes. From these isolates the amplification of the coagulase (coa) gene yielded three different PCR products approximately 204bp to 490bp while spa (spa-X) gene produced five different products ranging in size from 190bp to 320bp. PCR revealed that from all the coagulase positive S. aureus isolates 261(98.5%) had spa (spa-X) gene. The results of the present study indicated that S. aureus isolates recovered from bovine mastitis were genetically different within and among the various herds which may provide essential and valuable strategies to control staphylococcal infections in future.

The positive quarter milk samples were collected for culturing of S. aureus isolates. taphylococcus aureus isolates were identified on the basis of growth features, biochemical characteristics, coagulase test and as well as amplification of coagulase (coa) and spa (spa-X) genes specific to its virulence. S. aureus isolates (n=265) were characterized by Polymerase chain reaction to determine the frequency of coagulase (coa) and spa (spa-X) genes. From these isolates the amplification of the coagulase (coa) gene yielded three different PCR products approximately 204bp to 490bp while spa (spa-X) gene produced five different products ranging in size from 190bp to 320bp. PCR revealed that from all the coagulase positive S. aureus isolates 261(98.5%) had spa (spa-X) gene. The results of the present study indicated that S. aureus isolates recovered from bovine mastitis were genetically different within and among the various herds which may provide essential and valuable strategies to control staphylococcal infections in future.

    2014-05-01

    Visible and short wave infrared spectroscopy (Vis/SW-NIRS) was investigated in the present study for measurement of soil organic matter (OM) and available potassium (K). Four types of pretreatments including smoothing, SNV, MSC and SG smoothing+first derivative were adopted to eliminate the system noises and external disturbances. Then partial least squares regression (PLSR) and least squares-support vector machine (LS-SVM) models were implemented for calibration models. The LS-SVM model was built by using characteristic wavelength based on successive projections algorithm (SPA). Simultaneously, the performance of LSSVM models was compared with PLSR models. The results indicated that LS-SVM models using characteristic wavelength as inputs based on SPA outperformed PLSR models. The optimal SPA-LS-SVM models were achieved, and the correlation coefficient (r), and RMSEP were 0. 860 2 and 2. 98 for OM and 0. 730 5 and 15. 78 for K, respectively. The results indicated that visible and short wave near infrared spectroscopy (Vis/SW-NIRS) (325 approximately 1 075 nm) combined with LS-SVM based on SPA could be utilized as a precision method for the determination of soil properties.

  10. Insulin utilizes the PI 3-kinase pathway to inhibit SP-A gene expression in lung epithelial cells

    Directory of Open Access Journals (Sweden)

    2002-10-01

    Full Text Available Abstract Background It has been proposed that high insulin levels may cause delayed lung development in the fetuses of diabetic mothers. A key event in lung development is the production of adequate amounts of pulmonary surfactant. Insulin inhibits the expression of surfactant protein A (SP-A, the major surfactant-associated protein, in lung epithelial cells. In the present study, we investigated the signal transduction pathways involved in insulin inhibition of SP-A gene expression. Methods H441 cells, a human lung adenocarcinoma cell line, or human fetal lung explants were incubated with or without insulin. Transcription run-on assays were used to determine SP-A gene transcription rates. Northern blot analysis was used to examine the effect of various signal transduction inhibitors on SP-A gene expression. Immunoblot analysis was used to evaluate the levels and phosphorylation states of signal transduction protein kinases. Results Insulin decreased SP-A gene transcription in human lung epithelial cells within 1 hour. Insulin did not affect p44/42 mitogen-activated protein kinase (MAPK phosphorylation and the insulin inhibition of SP-A mRNA levels was not affected by PD98059, an inhibitor of the p44/42 MAPK pathway. In contrast, insulin increased p70 S6 kinase Thr389 phosphorylation within 15 minutes. Wortmannin or LY294002, both inhibitors of phosphatidylinositol 3-kinase (PI 3-kinase, or rapamycin, an inhibitor of the activation of p70 S6 kinase, a downstream effector in the PI 3-kinase pathway, abolished or attenuated the insulin-induced inhibition of SP-A mRNA levels. Conclusion Insulin inhibition of SP-A gene expression in lung epithelial cells probably occurs via the rapamycin-sensitive PI 3-kinase signaling pathway.

    1995-01-01

    A small hydro plant in Canada is defined as any project between 1 MW and 15 MW but the international standard is 10 MW. The global market for small hydro development was considered good. There are some 1000 to 2000 MW of generating capacity being added each year. In Canada, growth potential is considered small, primarily in remote areas, but significant growth is anticipated in Eastern Europe, Africa and Asia. Canada with its expertise in engineering, manufacturing and development is considered to have a good chance to take advantage of these growing markets

  12. SWOT ANALYSIS OF SPA TOURISM IN BULGARIA

    2016-06-01

    Full Text Available Our time is marked by the increasingly dynamic changing environment. The new conditions in which we operate are characterized by increasing complexity and labor activities that require more responsible behavior. The rising levels of stress and the increasing lack of free time for relaxation and recreation require a new look at the possibilities for the prevention of personal health. The plane of the consumer society in which we live is increasingly shifted by aspiration and vision of an environmentally friendly lifestyle. The focus here is the implementation of a multilevel wellness concept that changes qualitatively the status quo and seeks for ways to harmonize the body with the nature. One of the options is the practice of SPA tourism in whose genesis is the multilayered beneficial impact of a series of procedures and actions. This new alternative through its economic dimensions is an attractive business niche which over time becomes an industry. The current state of the SPA tourism in Bulgaria is controversial despite existing achievements and introduced best practices. Traditions in this direction and the presence of favorable basis for its approval, however, are not sufficient to achieve stability and an upward trend in development. There are existing a number of weaknesses and negative aspects that create frustration in users, which is a real threat to its future. The proposed SWOT-analysis as part of a comprehensive and multilateral study of the state of SPA tourism in Bulgaria reveals some of the existing problems. There have been some suggestions to minimize the impact of weaknesses and eliminate the errors found in leading business organizations managing processes. A detailed analysis and evaluation of the formulated conclusions is ahead, as well as concluding on ideas to improve the state of the sector – a subject of a further investigation by the author.

    The Dalaelven hydro scheme is located in central Sweden. Fortum has in the scheme 50 dams and 35 hydro power plants producing 4 TWh energy with a capacity of 970 MW. The main reservoirs are Lake Siljan and Traengsletsjoen with Traengslet dam, the highest earth-filled dam in Sweden. Development of the hydro scheme started 1878 with construction of four power plants for industry until 1930. From 1931 to 1974 15 power plants were built for increasing electricity consumption. De-regulation of the energy market in 1990's and EU environmental targets in 2000's resulted in the rehabilitation of ten power plants between 1990 and 2014 with increased annual energy production of 377 GWh (29%) and capacity 124 MW (59%). This energy decreases the annual CO 2 emissions with 125918 tons in comparison to production of the same amount of energy by coal. In several cases the rehabilitation was made in new power houses, allowing the development of the layout and technology of civil structures, and use of state-of-art equipment. Sweden uses the green certificate system, and 235 GWh of the energy received this certificate. Other environmental benefits come from use of the environmentally friendly Kaplan turbines and construction of some new fish pass. There are further plans to increase the spillway capacity of Traengslet dam and to rehabilitate eight power plant units. The possibilities of obtaining the Environmental licences for the rehabilitations has became challenging in the past years and green certificates are nowadays agreed only for increased energy.

    Staphylococcus aureus causes life-threatening pneumonia in hospitals and deadly superinfection during viral influenza. The current study investigated the role of surfactant protein A (SP-A) in opsonization and clearance of S. aureus. Previous studies showed that SP-A mediates phagocytosis via the SP-A receptor 210 (SP-R210). Here, we show that SP-R210 mediates binding and control of SP-A-opsonized S. aureus by macrophages. We determined that SP-A binds S. aureus through the extracellular adhesin Eap. Consequently, SP-A enhanced macrophage uptake of Eap-expressing (Eap(+)) but not Eap-deficient (Eap(-)) S. aureus. In a reciprocal fashion, SP-A failed to enhance uptake of Eap(+) S. aureus in peritoneal Raw264.7 macrophages with a dominant negative mutation (SP-R210(DN)) blocking surface expression of SP-R210. Accordingly, WT mice cleared infection with Eap(+) but succumbed to sublethal infection with Eap- S. aureus. However, SP-R210(DN) cells compensated by increasing non-opsonic phagocytosis of Eap(+) S. aureus via the scavenger receptor scavenger receptor class A (SR-A), while non-opsonic uptake of Eap(-) S. aureus was impaired. Macrophages express two isoforms: SP-R210(L) and SP-R210(S). The results show that WT alveolar macrophages are distinguished by expression of SP-R210(L), whereas SR-A(-/-) alveolar macrophages are deficient in SP-R210(L) expressing only SP-R210(S). Accordingly, SR-A(-/-) mice were highly susceptible to both Eap(+) and Eap(-) S. aureus. The lungs of susceptible mice generated abnormal inflammatory responses that were associated with impaired killing and persistence of S. aureus infection in the lung. In conclusion, alveolar macrophage SP-R210(L) mediates recognition and killing of SP-A-opsonized S. aureus in vivo, coordinating inflammatory responses and resolution of S. aureus pneumonia through interaction with SR-A.

    2010-12-01

    Managing, handling and accessing hydrogeological information depends heavily on the applied hydrogeological data models, which differ between institutions and countries. The effective dissemination of hydrogeological information requires the convergence of such models to make hydrogeological information accessible to multiple users such as universities, water suppliers, and administration and research organisations. Furthermore, because hydrogeological studies are complex, they require a wide variety of high-quality hydrogeological data with appropriate metadata in clearly designed and coherent structures. A need exists, therefore, to develop and implement hydrogeological data models that cover, as much as possible, the full hydrogeological domain. A new data model, called HydroCube, was developed for the Walloon Region in Belgium in 2005. The HydroCube model presents an innovative holistic project-based approach which covers a full set of hydrogeological concepts and features, allowing for effective hydrogeological project management. The model stores data relating to the project locality, hydrogeological equipment, and related observations and measurements. In particular, it focuses on specialized hydrogeological field experiments such as pumping and tracer tests. This logical data model uses entity-relationship diagrams and it has been implemented in the Microsoft Access environment. It has been enriched with a fully functional user interface.

  17. Hydrogeothermal characteristics of groundwater from Ribarska Banja spa, central Serbia

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Ribarska Banja spa is one of the most popular balneotherapy and recreation centers in Serbia. It features several thermal groundwater sources whose temperatures range from 26 to 54°C. The mineral content of these waters is low and their composition is of the SO4-Na or HCO3-Na type. Thermal water exploration has been conducted in the general area for many years, to assess the hydrogeothermal potential in order to extract larger amounts of thermal water for multiple uses. The hydrogeothermal system of Ribarska Banja spa was defined based on a synthesis of the results of comprehensive structural geology, geophysical, hydrogeological, hydrochemical and geothermal research. The primary groundwater reservoir of the hydrogeothermal system is comprised of tectonic zones (systems of faults and fractures within Cretaceous-Paleogene metamorphosed and non-metamorphosed rocks. The overlying hydrogeological and temperature barrier is made up of a series of low metamorphosed rocks (chlorite, chlorite-sericite schists, gabbros, etc., highly metamorphosed rocks (gneisses and Neogene clay and sand sediments. The system is recharged by infiltration of atmospheric precipitation and surface water at the highest elevations of Mt. Jastrebac. Investigations have also shown that the system’s heat source is younger granitoide intrusion spreading northwest of Ribarska Banja spa. Based on the quartz geothermometers, expected reservoir temperatures are in the range of 85-97°C that can be expected at a depth of 1.87 km. Total energy usage at Ribarska Banja spa is 31 TJ/y with thermal capacity of 1.65 MWt and utilization factor of 0.58. Geothermal gradient is 0,051°C/m, while heat flow density is 163.5 mW/m2.

    Oxidative stress has been shown to play a contributory role in the pathogenesis of rheumatoid arthritis (RA). Recent studies have provided evidence for antioxidant properties of spa therapy. The purpose of this study is to investigate whether spa therapy with saline balneotherapy has any influence on the oxidant/antioxidant status in patients with RA and to assess clinical effects of spa therapy. In this investigator-blind randomized controlled trial, we randomly assigned 50 patients in a 1:1 ratio to spa therapy plus standard drug treatment (spa group) or standard drug treatment alone (control group). Spa group followed a 2-week course of spa therapy regimen consisting of a total of 12 balneotherapy sessions in a thermal mineral water pool at 36-37 °C for 20 min every day except Sunday. All clinical and biochemical parameters were assessed at baseline and after spa therapy (2 weeks). The clinical parameters were pain intensity, patient global assessment, physician global assessment, Health Assessment Questionnaire disability index (HAQ-DI), Disease Activity Score for 28-joints based on erythrocyte sedimentation rate (DAS28-4[ESR]). Oxidative status parameters were malondialdehyde (MDA), nonenzymatic superoxide radical scavenger activity (NSSA), antioxidant potential (AOP), and superoxide dismutase (SOD). The NSSA levels were increased significantly in the spa group ( p = 0.003) but not in the control group ( p = 0.509); and there was a trend in favor of spa therapy for improvements in NSSA levels compared to control ( p = 0.091). Significant clinical improvement was found in the spa group compared to the control in terms of patient global assessment ( p = 0.011), physician global assessment ( p = 0.043), function (HAQ-DI) ( p = 0.037), disease activity (DAS28-4[ESR]) (0.044) and swollen joint count (0.009), and a trend toward improvement in pain scores (0.057). Spa therapy with saline balneotherapy exerts antioxidant effect in patients with RA as reflected by the

    The Asian Pacific area offers good prospects for Canadian exports of equipment and expertise in the area of hydropower development. Rapidly growing economies in this area have large unsatisfied power demands, and many of these countries have significant undeveloped hydroelectric potential (notably China). Recent Canadian successes in Asia-Pacific hydropower developments are outlined, including the Chamera project in Himachal Pradesh, India; the feasibility study of the Three Gorges project, China; and technical assistance on a 5,000 MW hydroelectric project in Longtan, China. The issues facing Canada for developing and implementing long-term hydro development strategies are discussed. These issues are: establishing Canada's own energy needs; coordination and integration of Canadian hydro resource development; environmental issues and sustainable development; and realizing that energy exports are ethical. Benefits of domestic and international hydro development include environmental friendliness, creation of jobs and markets for Canadian products and expertise, and stimulation of technological and economic development. 1 tab.

  1. The Role of Aspiration Level in Risky Choice: A Comparison of Cumulative Prospect Theory and SP/A Theory.

    Science.gov (United States)

    Lopes; Oden

    1999-06-01

    In recent years, descriptive models of risky choice have incorporated features that reflect the importance of particular outcome values in choice. Cumulative prospect theory (CPT) does this by inserting a reference point in the utility function. SP/A (security-potential/aspiration) theory uses aspiration level as a second criterion in the choice process. Experiment 1 compares the ability of the CPT and SP/A models to account for the same within-subjects data set and finds in favor of SP/A. Experiment 2 replicates the main finding of Experiment 1 in a between-subjects design. The final discussion brackets the SP/A result by showing the impact on fit of both decreasing and increasing the number of free parameters. We also suggest how the SP/A approach might be useful in modeling investment decision making in a descriptively more valid way and conclude with comments on the relation between descriptive and normative theories of risky choice.

    2001-01-01

    In Spain, the benefits of small-scale (less than 10 MW) hydro are apparently rarely appreciated and there is little support from European institutions. The article suggests that small hydro technology can make a significant contribution to the country's energy requirements and create employment, provided certain obstacles can be removed. Data on the number of small hydros in Spain, and of recent installations are given; the share of hydro in Spain's total energy production is 2.5%. The low environmental impact of hydro is extolled, and the conclusions of a recent study of 'environmental impacts of the production of electricity' are listed. There are said to be unreasonable administrative obstacles; for example, it is more difficult to obtain permission to refurbish a 100 kW hydro plant in Castilla y Leon than it is to install a 30,000 kW gas plant. Some details relating to the affect of hydro on aquatic ecosystems, noise levels, and water quality, are given

    Staphylococcus aureus is an opportunistic pathogen causing infections in humans and animals. Here we report for the first time the prevalence of nasal carriage, spa typing and antimicrobial resistance of S. aureus in a Tanzanian livestock community. Nasal swabs were taken from 100 humans, 100 pigs and 100 dogs in Morogoro Municipal. Each swab was enriched in Mueller Hinton broth with 6.5% NaCl and subcultured on chromogenic agar for S. aureus detection. Presumptive S. aureus colonies were confirmed to the species level by nuc PCR and analysed by spa typing. Antimicrobial susceptibility patterns were determined by disc diffusion method. S. aureus was isolated from 22% of humans, 4% of pigs and 11% of dogs. A total of 21 spa types were identified: 13, 7 and 1 in human, dogs, and pigs, respectively. Three spa types (t314, t223 and t084) were shared between humans and dogs. A novel spa type (t10779) was identified in an isolate recovered from a colonized human. Antimicrobials tested revealed resistance to ampicillin in all isolates, moderate resistances to other antimicrobials with tetracycline resistance being the most frequent. S. aureus carrier frequencies in dogs and humans were within the expected range and low in pigs. The S. aureus spa types circulating in the community were generally not shared by different hosts and majority of types belonged to known clones. Besides ampicillin resistance, moderate levels of antimicrobial resistance were observed irrespective of the host species from which the strains were isolated.

    2009-01-01

    The South Pole-Aitken (SPA) basin is an important target for absolute age-dating. Vertical and lateral impact mixing ensures that regolith within SPA will contain rock fragments from SPA itself, local impact craters, and faraway giant basins. About 20% of the regolith at any given site is foreign [1, 2], but much of this material will be cold ejecta, not impact melt. We calculated the fraction of contributed impact melt using scaling laws to estimate the amount and provenance of impact melt, demonstrating that SPA melt is the dominant impact melt rock (>70%) likely to be present. We also constructed a statistical model to illustrate how many randomly-selected impact-melt fragments would need to be dated, and with what accuracy, to confidently reproduce the impact history of a site. A detailed impact history becomes recognizable after a few hundred to a thousand randomly-selected marbles, however, it will be useful to have more information (e.g. compositional, mineralogical, remote sensing) to group fragments. These exercises show that SPA melt has a high probability of being present in a scoop sample and that dating of a few hundred to a thousand impact-melt fragments will yield the impact history of the SPA basin.

    The presence of pathogenic microorganisms in public spa pools poses a serious threat to human health. The problem is particularly acute in herbal spas, in which the herbs and microorganisms may interact and produce undesirable consequences. Accordingly, the present study investigated the effectiveness of a combined disinfectant containing chlorine dioxide and sodium hypochlorite in improving the water quality of a public herbal spa in Taiwan. Water samples were collected from the spa pool and laboratory tests were then performed to measure the variation over time of the microorganism content (total CFU and total coliforms) and residual disinfectant content given a single disinfection mode (SDM) with disinfectant concentrations of 5.2 × 10, 6.29 × 10, 7.4 × 10, and 11.4 × 10(-5) N, respectively. Utilizing the experience gained from the laboratory tests, a further series of on-site investigations was performed using three different disinfection modes, namely SDM, 3DM (once every 3 h disinfection mode), and 2DM (once every 2 h disinfection mode). The laboratory results showed that for all four disinfectant concentrations, the CFU concentration reduced for the first 6 h following SDM treatment, but then increased. Moreover, the ANOVA results showed that the sample treated with the highest disinfectant concentration (11.4 × 10(-5) N) exhibited the lowest rate of increase in the CFU concentration. In addition, the on-site test results showed that 3DM and 2DM treatments with disinfectant concentrations in excess of 9.3 × 10 and 5.5 × 10(-5) N, respectively, provided an effective reduction in the total CFU concentration. In conclusion, the experimental results presented in this study provide a useful source of reference for spa businesses seeking to improve the water quality of their spa pools.

    Beauty industry grows vastly in the scope of regional, national, or international. Beauty industry includes Spa service. It becomes one of the choices where the urban citizen can use it to release their stress and relax their mind. This business grows as the development of technology. Spa industry should be able to provide the best service for physical and mental therapy, it will make the user of the service can be freed from their business and stress in the respective time to be healthies, more beautiful, and able to do their activity maximally. Spa treatment consists of hair creambath, facial treatment, manicure-pedicure, scrub treatment, foot spa, aromatherapy, and body treatment with traditional cosmetics which are easy to get in Indonesia. Beauty education is one of the programs in Home Economics Department of Engineering Faculty of UNNES. This program was established to produce graduates in beauty fields as Vocational High School teachers with bachelor (S1) qualification. The graduates suppose to be excellent, professional, skillful, and care to the environment, culture, and social condition around them. It prepares them as teachers of beauty (in formal and non- formal education). Besides, it also prepared them to have professional competence in production fields of beauty service with adaptive, creative, and innovative which can be entrepreneurs who are able to create job vacancies for others.

    2016-09-01

    Full Text Available Power is considered as the major back bone for all the nations throughout the world including India on the basis of which development of the country depends. If a country has the resources to generate the power at competitive price in that case the people of the country get the benefits in terms of improvement in their social and economical life. When we talk about India, various locations in the country where still there is no electricity people are living in dark without having the access of the modern technology. The total hydro power potential of India is 1, 50,000 MW out of this total hydro potential only 40,195 MW is exploited till 2014. More than 80% of the total hydro potential of the country is lying in the western Himalayan states (Jammu and Kashmir, Himachal Pradesh, Uttrakhand and Arunachal Pradesh. Small hydro projects are also playing a very important role in the modern world for the development of the remote areas which are not main grid connected specially in western Himalayan region of India. India has a total potential 19,749 MW of small hydro projects and of this total potential only 3990.9 MW harnessed till 2014. Ministry of new and renewable energy in India is also providing special incentives to hydro rich states of India. In this research article we are taken the case study of the small hydro projects in the western Himalayan region because theses states are having vast small hydro potential which is still needed to be harnessed. So, it is very important to identify the factors which are effecting the development of these small ventures especially in western Himalayan region in India.

    The current study presents the results of the activity of radionuclides in spa waters, and evaluates their radiological influences on the population consuming these waters in the Central and Eastern Black Sea regions of Turkey. Since these waters are used for therapy and consumption purposes unconsciously, their radiological impact on the people was computed by taking into consideration the annual intake through ingestion of 226 Ra, 232 Th, 40 K, 137 Cs and 222 Rn. The mean activities were estimated to be 11.35 for gross alpha, 6.23 for gross beta, 2.96 for 226 Ra, 0.42 for 232 Th, 0.069 for 137 Cs, 0.19 for 40 K, and 267 Bq L -1 for 222 Rn, respectively. The estimated effective doses from spa water were found to be 49.77 µSv a -1 ( 226 Ra), 5.95 µSv a -1 ( 232 Th), 0.07 µSv a -1 ( 137 Cs), 0.83 µSv a -1 ( 40 K) and 56.03 µSv a -1 ( 222 Rn). These values were evaluated and compared with related verified values from literature. Also, physico-chemical characterizations of spa water samples considered in the current study were investigated. This study would be useful for consumers and official authorities for the assessment of radiation exposure risk due to usage of the considered spa waters.

    2006-01-01

    Hydro-Quebec produces, transmits and distributes electricity through the use of renewable energy sources, particularly hydroelectricity. It also conducts research in energy related fields. This document listed the strategic plan for Hydro-Quebec's 4 main divisions: Hydro-Quebec Production, Hydro-Quebec TransEnergie, Hydro-Quebec Distribution and Hydro-Quebec Energy Society of Bay James. The 2006 to 2010 strategic plan continues to focus on 3 main priorities: energy efficiency; complementary development of hydroelectricity and wind power; and, technological innovation. Hydro-Quebec's objectives also include strengthening the security of Quebec's energy supply and making use of energy as a lever for economic development. The plan for Hydro-Quebec Production calls for accelerating the development of major hydroelectric projects and promoting other renewable forms of energy such as wind power and ensuring the efficiency and reliability of the generating fleet. The utility's objective is to reach 4.7 TWh in energy savings by 2010 and to work toward a target of 8 TWh by 2015. The plan also involves a portfolio of hydroelectric projects totaling 5,400 MW. The plan includes complementary development and integration of 4,000 MW of windpower by 2015. The plan for Hydro-Quebec TransEnergie calls for system reliability and becoming a world benchmark for quality and reliability in wind power integration and deployment of new technologies to enhance performance. The plan for Hydro-Quebec Distribution calls for more efficient use of electricity, increase customer satisfaction and meet electricity needs through the use of renewable energy sources. The utility has made a commitment for 2006 to 2010 to a net income of $2.5 billion per year for a total of $12.5 billion, and a capital investment of 19.4 billion. This paper outlined the contribution of each division to net income and listed the economic benefits for the 2006 to 2010 period. In 2006, the Quebec Energy Board authorized

  18. New markets for small-scale hydro

    International Nuclear Information System (INIS)

    Maurer, E.A.

    1997-01-01

    The market for small and medium sized hydro-electric power plant is more attractive than ever. The boom in Europe has increasingly spread to the emerging countries, and here too small hydro plays an important ecological role. In addition to new plant rehabilitation of 'historical' plant is now a major factor. The last few years have seen a market shift from single machine components to complete plant and systems, requiring a strategy re-think on the part of larger companies. Following the influx of private capital into the power industry, business conditions have also undergone a thorough transformation. In place of 'fast money', hydro power offers the prospect of earning longer-term, sustainable money'. The term small-scale hydro-electric power (or simply 'small hydro') is used slightly differently depending on the country and market. Here, it is used to denote plant with turbines up to 10 MW.

  20. Standardized CSR and climate performance: why is Shell willing, but Hydro reluctant?; Shell; Hydro

    Energy Technology Data Exchange (ETDEWEB)

    Boasson, Elin Lerum; Wettestad, Joergen

    2007-06-15

    This report aims to contribute to the ongoing discussion concerning whether CSR merely serves to streamline company rhetoric or also has an influence on actual efforts. We discuss the tangible effects of CSR instruments on the climate-related rules and performances of the two different oil companies Hydro and Shell. First we explore whether similar CSR instruments lead to similar climate-related rules and practices in the two companies. Both Hydro and Shell adhere to the Global Compact (GC), the Global Reporting Initiative (GRI), the Carbon Disclosure Project (CDP) and the Global Gas Flaring Reduction Public-Private Partnership (GGFR). The report concludes that the GC has not rendered any tangible effects in either of the companies. Concerning the other instruments, Hydro has only followed the instrument requirements that fit their initial approach, and refrained from all deviating requirements. Shell has been more malleable, but we have noted few effects on the actual emissions and business portfolio resulting from the instrument adherence. Second, we assess how the differing results of the similar CSR portfolio may be explained. The reluctant attitude of the leaders in Hydro and the strong CSR motivation of Shell's executives result in significant differences. Hydro executives are able to constrain the effects of the instrument adherence. With Shell we note the opposite pattern: Its leaders promoted the instruments to be translated into internal rules, but a general lack of hierarchical structures hinders them from governing the conduct of various sub-organisations. The very diversity of the Shell culture helps to explain why the efforts of its executives have resulted in limited impact. The strength of the Hydro culture makes the corporation resistant to the instruments. Moreover, Hydro is strikingly shielded by virtue of its strong position in Norway. In contrast, Shell is more strongly affected by the global field of petroleum and the global field of CSR

    The article outlines the history of hydro in Portugal and discusses the current position of small-scale hydro with particular reference to the Portuguese Small Hydro Association (AMPH). Encouraged by legislation, and the Valoren community programme (which defined investment incentives), many new small hydro projects sprang up in Portugal in the 1990s. In some areas of Portugal the water levels were higher than the urban centres where the water is required: how the problems of integrating power and water were addressed is described. The integration of power and irrigation schemes is also mentioned. In the wake of great expansion in the Portuguese hydro industry, there was a sharp reduction (in 1995-6) and the reasons for that are listed. The 1999 tariff was such that it is likely that small hydro will provide 3.8% of the electric power consumed nationally by 2010

    Babouee, B.; Frei, R.; Schultheiss, E.; Widmer, A. F.; Goldenberger, D.

    2011-01-01

    The emergence of methicillin-resistant Staphylococcus aureus (MRSA) has become an increasing problem worldwide in recent decades. Molecular typing methods have been developed to identify clonality of strains and monitor spread of MRSA. We compared a new commercially available DiversiLab (DL) repetitive element PCR system with spa typing, spa clonal cluster analysis, and pulsed-field gel electrophoresis (PFGE) in terms of discriminatory power and concordance. A collection of 106 well-defined MRSA strains from our hospital was analyzed, isolated between 1994 and 2006. In addition, we analyzed 6 USA300 strains collected in our institution. DL typing separated the 106 MRSA isolates in 10 distinct clusters and 8 singleton patterns. Clustering analysis into spa clonal complexes resulted in 3 clusters: spa-CC 067/548, spa-CC 008, and spa-CC 012. The discriminatory powers (Simpson's index of diversity) were 0.982, 0.950, 0.846, and 0.757 for PFGE, spa typing, DL typing, and spa clonal clustering, respectively. DL typing and spa clonal clustering showed the highest concordance, calculated by adjusted Rand's coefficients. The 6 USA300 isolates grouped homogeneously into distinct PFGE and DL clusters, and all belonged to spa type t008 and spa-CC 008. Among the three methods, DL proved to be rapid and easy to perform. DL typing qualifies for initial screening during outbreak investigation. However, compared to PFGE and spa typing, DL typing has limited discriminatory power and therefore should be complemented by more discriminative methods in isolates that share identical DL patterns.

    Piro, P.

    2010-01-01

    On average the hydro-power sector produces 12% of the electrical power in France. A quarter of this production might pass to another operator than EDF because the end of some grants is nearing (2012 for 12 installations). In France the power of rivers belongs to the state that gives operators grants to harness it. The allowance lasts 75 years usually but for installations below 4.5 MW a permanent and definitive grant is allowed. Most installations are ancient and their investment have been paid off since a long, so hydro-power is the most profitable renewable energy in France. A lot of bidders are expected. Each bid will be assessed on 3 criteria: -) the global energy efficiency of the waterfall, -) a balanced management of the water resource, and -) an economic and financial offer to the state. The balance between the different uses of water is getting more delicate to reach and this renewal of grants will be an opportunity for the state to impose a better preservation of the environment. In July 2008, the French government announced a program for the re launching of the hydro-power, this program has been reduced and now only 3000 GWh supplementary are expected by 2020. (A.C.)

  7. Effects of balneotherapy and spa therapy on levels of cortisol as a stress biomarker: a systematic review

    Science.gov (United States)

    Antonelli, Michele; Donelli, Davide

    2018-02-01

    Balneotherapy and spa therapy are well-known practices, even though limited evidence has been produced about their biological effects. This systematic review primarily aims at assessing if balneotherapy, mud/peloid therapy, and spa therapy may influence cortisol levels. Secondarily, it aims at understanding if these interventions may improve stress resilience. PubMed/Medline, Embase, and Cochrane Library were searched for relevant articles in English or Italian about studies involving healthy and sub-healthy subjects or patients with a diagnosed disease about effects of balneotherapy, mud/peloid therapy, and spa therapy on serum and salivary cortisol levels. Fifteen studies involving 684 subjects were included. Five studies investigated biological effects of balneotherapy alone. Two of them reported significant changes of cortisol levels in healthy participants. The other three studies reported no significant variations in patients with rheumatic conditions. No studies investigated biological effects of mud/peloid therapy alone. Ten studies investigated biological effects of spa therapy with or without included mud/peloid therapy, and in all but two studies, significant variations of cortisol levels were reported. Our main findings suggest that balneotherapy may have the potential to influence cortisol levels in healthy subjects, in such a way as to improve stress resilience. Spa therapy with or without included mud/peloid therapy demonstrated the same potential to influence cortisol levels also in sub-healthy subjects and in patients with a diagnosed disease. Therefore, balneotherapy and spa therapy may be considered as useful interventions for the management of stress conditions. Further investigation is needed because of limited available data.

  8. Hydro-thermal power flow scheduling accounting for head variations

    International Nuclear Information System (INIS)

    El-Hawary, M.E.; Ravindranath, K.M.

    1992-01-01

    In this paper the authors treat the problem of optimal economic operation of hydrothermal electric power systems with variable head hydro plants employing the power flow equations to represent the network. Newton's method is used to solve the problem for a number of test systems. A comparison with solutions with fixed head is presented. In general the optimal schedule requires higher slack bus and thermal power generation and cost in the case of variable head hydro plant than that required by the fixed head hydro plant in all demand periods. Correspondingly, the hydro generation is less in the case of variable head hydro plant compared to fixed head hydro plant. A negligible difference in voltage magnitudes in all the time intervals, but it is observed that slightly higher voltages occur in the case of the fixed head hydro plant. Higher power and energy losses occur in the case of variable head hydro plants compared to the fixed head hydro plants

    SpaE is the predicted basal pilin subunit in the sortase-dependent SpaFED pilus from the gut-adapted and commensal Lactobacillus rhamnosus GG. Thus far, structural characterization of the cell-wall-anchoring basal pilins has remained difficult and has been limited to only a few examples from pathogenic genera and species. To gain a further structural understanding of the molecular mechanisms that are involved in the anchoring and assembly of sortase-dependent pili in less harmful bacteria, L. rhamnosus GG SpaE for crystallization was produced by recombinant expression in Escherichia coli. Although several attempts to crystallize the SpaE protein were unsuccessful, trigonal crystals that diffracted to a resolution of 3.1 Å were eventually produced using PEG 3350 as a precipitant and high protein concentrations. Further optimization with a combination of additives led to the generation of SpaE crystals in an orthorhombic form that diffracted to a higher resolution of 1.5 Å. To expedite structure determination by SAD phasing, selenium-substituted (orthorhombic) SpaE crystals were grown and X-ray diffraction data were collected to 1.8 Å resolution.

  12. Energy efficiency at Hydro-Quebec: Why forget the substitution of electricity by natural gas?

    International Nuclear Information System (INIS)

    Bernard, J.-T.

    1994-01-01

    Hydro-Quebec has launched an energy program which will cost $1.9 billion and which intends to save 9.3 TWh of electricity consumption by the year 2000, equivalent to 5.6% of the forecasted electricity consumption. The program only considers electricity and ignores other energy sources. An analysis is conducted to determine whether the subsidies that Hydro-Quebec is prepared to spend in each sector of the program would be sufficient to make up the difference between the cost of electricity and that of natural gas for the end-user. A positive response to this question will allow identification of a less costly way that Hydro-Quebec could realize its energy efficiency objectives. The analysis takes into account the marginal cost of electricity production, the average cost of energy efficiency measures, electricity prices, and the prices of natural gas and of gas-burning equipment. The results of a detailed analysis of four typical cases in the residential and commercial sectors indicate that market segments exist in which an energy efficiency program that includes substitution of other forms of energy for electricity would be preferable to a simple reduction in electricity consumption. However, the rationale for the Hydro-Quebec program is that electricity prices are based on historical average costs; as a result, electricity prices are lower than marginal costs. This problem should be addressed before considering expensive energy efficiency programs where the least-cost alternative is not even considered. 5 refs., 1 fig., 2 tabs

    2015-09-01

    The viability of modular pumped storage hydro (m-PSH) is examined in detail through the conceptual design, cost scoping, and economic analysis of three case studies. Modular PSH refers to both the compactness of the project design and the proposed nature of product fabrication and performance. A modular project is assumed to consist of pre-fabricated standardized components and equipment, tested and assembled into modules before arrival on site. This technology strategy could enable m-PSH projects to deploy with less substantial civil construction and equipment component costs. The concept of m-PSH is technically feasible using currently available conventional pumping and turbine equipment, and may offer a path to reducing the project development cycle from inception to commissioning.

    1992-01-01

    Since the dawn of civilization, man has captured the energy potential of falling water, from the water wheels in the fertile crescent of ancient times to today's highly sophisticated conventional and pumped storage projects. As we approach the 21st century, electric energy captured from falling water provides 2.0 trillion kilowatt-hours (21.23 quadrillion Btu), roughly 20% of the world's electric energy. Of the 2.56 billion kilowatts of the world's installed electric generating capacity, hydropower accounts for 24%. Between 1980 and 1989, world generation of hydroelectric power rose from 1.7 trillion kWh to 2.0 trillion kWh. As of January 1, 1988, the US has 90.5 million kW of installed hydro capacity - 70.8 million kW of it under license by the Federal Energy Regulatory Commission - with annual generation estimated at just under 300 billion kWh. Hydro's share, which not long ago comprised 13% of the nation's total capacity, now is just a 9% share. The US has the option to choose one or another path for hydro. If policy makers are willing to coast on a cushion of cheap natural gas, they will continue to shun hydro and put obstacles in its path. But if they come to regard hydro as an attractive resource - as they did only recently - economically and environmentally, they will encourage more balance in resource policies. Believing that interest in a balanced national resource portfolio will grow, the author reviews the past and suggests a possible future course of reasonable development for hydro. The article concludes with some suggested principles that will be needed if the appropriate balance is to be found

    Full text: The era of new, large hydro-power development projects seems to be over in Norway. Partly as a response to this, a large number of applications for the development of smallscale hydro power projects up to 10 MW overflow the Water Resources and Energy Directorate, resulting in an extensive development of small tributaries and water courses in Norway. This study has developed a framework for the assessment and comparison of several small versus many large hydro-power projects based on a multi-criteria analysis (MCA) approach, and further tested this approach on planned or developed projects in the Helgeland region, Norway. Multi-criteria analysis is a decision-support tool aimed at providing a systematic approach for the comparison of various alternatives with often non-commensurable and conflicting attributes. At the same time, the technique enables complex problems and various alternatives to be assessed in a transparent and simple way. The MCA-software was in our case equipped with 2 overall criteria (objectives) with a number of sub criteria; Production with sub-criteria like volume of energy production, installed effect, storage capacity and economical profit; Environmental impacts with sub-criteria like fishing interests, biodiversity, protection of unexploited nature The data used in the case study is based on the planned development of Vefsna (large project) with the energy/effect production estimated and the environmental impacts identified as part of the feasibility studies (the project never reached the authorities' licensing system with a formal EIA). The small-scale hydro-power projects used for comparison are based on realized projects in the Helgeland region and a number of proposed projects, up scaled to the size of the proposed Vefsna-development. The results from the study indicate that a large number of small-scale hydro-power projects need to be implemented in order to balance the volume of produced electricity/effect from one

    1985-03-01

    The micro-hydro project, built on a small tributary of Cowley Creek, near Whitehorse, Yukon, is an important step in the development of alternative energy sources and in conserving expensive diesel fuel. In addition to demonstrating the technical aspects of harnessing water power, the project paved the way for easier regulatory procedures. The power will be generated by a 9 meter head and a 6 inch crossflow turbine. The 36 V DC power will be stored in three 12 V batteries and converted to ac on demand by a 3,800 watt inverter. The system will produce 1.6 kW or 14,016 kWh per year with a firm flow of 1.26 cfs. This is sufficient to supply electricity for household needs and a wood working shop. The project is expected to cost about $18,000 and is more economical than tying into the present grid system, or continuing to use a gasoline generator. An environmental study determined that any impact of the project on the stream would be negligible. It is expected that no other water users will be affected by the project. This pilot project in micro-hydro applications will serve as a good indicator of the viability of this form of alternate energy in the Yukon. The calculations comparing the micro-hydro and grid system indicate that the mico-hydro system is a viable source of inflation-proof power. Higher heads and larger flow resulting in ac generation in excess of 10 kW would yield much better returns than this project. 3 tabs.

    A fluidized-bed bioreactor was used to treat the industrial wastewater containing linear alkylbenzene sulfonate(LAS). Microorganism obtained by acclimation showed low growth rate and substrate inhibition at relatively high substrate concentration. It was found from the experiment using fluidized-bed bioreactor that 64 {mu}m-thick biofilm was made after 15 days. The 93.4% LAS removal efficiency in the reactor was obtained at 120 mg/L of initial LAS concentration, while the removal efficiency of sulfophenylalkannoates(SPA) which is a representative intermediate of biodegradation of LAS was 60-88% depending on the initial concentration of LAS. When sodium benzoate was added to the second reactor, the remaining SPA became lowered by 40% compared to the control experiment. And when activated carbon was added to the reactor, the removal efficiency of SPA was 96.2% and that of LAS was 100% when initial inflowing concentration of LAS was 350 mg/L. 13 refs., 4 tabs., 8 figs.

  7. Structural and Biochemical Characterization of Spa47 Provides Mechanistic Insight into Type III Secretion System ATPase Activation and Shigella Virulence Regulation*

    Like many Gram-negative pathogens, Shigella rely on a complex type III secretion system (T3SS) to inject effector proteins into host cells, take over host functions, and ultimately establish infection. Despite these critical roles, the energetics and regulatory mechanisms controlling the T3SS and pathogen virulence remain largely unclear. In this study, we present a series of high resolution crystal structures of Spa47 and use the structures to model an activated Spa47 oligomer, finding that ATP hydrolysis may be supported by specific side chain contributions from adjacent protomers within the complex. Follow-up mutagenesis experiments targeting the predicted active site residues validate the oligomeric model and determined that each of the tested residues are essential for Spa47 ATPase activity, although they are not directly responsible for stable oligomer formation. Although N-terminal domain truncation was necessary for crystal formation, it resulted in strictly monomeric Spa47 that is unable to hydrolyze ATP, despite maintaining the canonical ATPase core structure and active site residues. Coupled with studies of ATPase inactive full-length Spa47 point mutants, we find that Spa47 oligomerization and ATP hydrolysis are needed for complete T3SS apparatus formation, a proper translocator secretion profile, and Shigella virulence. This work represents the first structure-function characterization of Spa47, uniquely complementing the multitude of included Shigella T3SS phenotype assays and providing a more complete understanding of T3SS ATPase-mediated pathogen virulence. Additionally, these findings provide a strong platform for follow-up studies evaluating regulation of Spa47 oligomerization in vivo as a much needed means of treating and perhaps preventing shigellosis.

    Full Text Available Background/Aim. Treatment of psoriasis is very complex and there are no still universal, nor unique treatment modalities. Apart from conventional treatment, which includes topical calcipotriol (vitamin D3 analogue, balneotherapy is drawing increased attention worldwide. Being part of climatotherapy, balneotherapy is defined as the use of natural environmental factors in the treatment of health conditions, whereas in the treatment of psoriasis it means the use of mineral baths and peloids. The aim of this study was to examine the therapeutic efficacy of mineral waters and peloids of the Rusanda Spa on plaque psoriasis in patients also treated with calcipotriol. Methods. The study included 60 patients divided into two groups. The first group included patients treated with mineral waters, peloids and calcipotriol in the Rusanda Spa, while the second one included those treated only with calcipotriol. The study took 21 days, and each patient was followed up for at least one month after ending the treatment. The treatment efficacy was measured by psoriasis area severity index (PASI scores on the days 0, 7, 14 and 21 during the treatment and 30 after the end of the therapy. Results. After a 3-week treatment in the Rusanda Spa, the first group showed a decrease in PASI score by 59.45%, whereas in the group of outpatients treated by calcipotriol it was 39.34%. On the day 30 following the treatment, the first group presented with the PASI score reduction of 58.44%, and the second group of 34.78%. The therapeutic efficacy of mineral waters and peloids combined with calcipotriol showed to be significantly higher in regard to monotherapy with calcipotriol (p < 0.05. In regard to clinical symptoms, the best results were obtained in the reduction of desquamation (p < 0.001. Conclusion. The results of our study show that in the treatment of plaque-type psoriasis, topical calcipotriol combined with Spa Rusanda balneotherapy is more effective than topical

    Background Staphylococcus aureus is both human commensal and an important human pathogen, responsible for community-acquired and nosocomial infections ranging from superficial wound infections to invasive infections, such as osteomyelitis, bacteremia and endocarditis, pneumonia or toxin shock syndrome with a mortality rate up to 40%. S. aureus reveals a high genetic polymorphism and detecting the genotypes is extremely useful to manage and prevent possible outbreaks and to understand the route of infection. One of current and expanded typing method is based on the X region of the spa gene composed of a succession of repeats of 21 to 27 bp. More than 10000 types are known. Extracting the repeats is impossible by hand and needs a dedicated software. Unfortunately the only software on the market is a commercial program from Ridom. Findings This article presents DNAGear, a free and open source software with a user friendly interface written all in Java on top of NetBeans Platform to perform spa typing, detecting new repeats and new spa types and synchronizing automatically the files with the open access database. The installation is easy and the application is platform independent. In fact, the SPA identification is a formal regular expression matching problem and the results are 100% exact. As the program is using Java embedded modules written over string manipulation of well established algorithms, the exactitude of the solution is perfectly established. Conclusions DNAGear is able to identify the types of the S. aureus sequences and detect both new types and repeats. Comparing to manual processing, which is time consuming and error prone, this application saves a lot of time and effort and gives very reliable results. Additionally, the users do not need to prepare the forward-reverse sequences manually, or even by using additional tools. They can simply create them in DNAGear and perform the typing task. In short, researchers who do not have commercial software will

    2014-01-01

    The plaque psoriasis, one of the most common form of psoriasis, is a chronic inflammatory disease. This pathology can cause devastating effects on quality of life and social relations with significant physical and psychological distress. Currently among the therapeutic agents available for the treatment of psoriasis is including SPA therapy, whose mechanism of action is only partially known, as well as very few studies examined the impact of this therapy on the quality of life. On the basis of these considerations, the research analyzed the effectiveness of SPA bath therapy (BLT) and its impact on quality of life and psychological distress in patients suffering from chronic plaque psoriasis. The study was conducted on 35 patients with chronic plaque psoriasis: 23% male and 77% female; mean age:56 ± 19 years; age range:17-85 years. The subjects were treated, for 2 weeks, with sulphureous SPA bath therapy from Terme of Telese SpA (Benevento-Italy). At the beginning and at the end of the SPA treatment considered was evaluated: the itching symptom (using NRS scale); the PASI Index; the impact on quality of life (using SF-36 and DLQI questionnaires) and on psychological distress (using ZUNG -tests). At the end of the SPA treatment, the mean values ± SD, compared to baseline, have showed a significant (p 1.0 ± 1.0) and PASI score (4 ± 4-->1.7 ± 2) with an improvement in quality of life and psichological distress as demonstrated by SF-36, DLQI and ZUNG tests. The data of this research show that the sulphureous SPA bath therapy can be considered very useful in patients with mild-to-moderate psoriasis for the improving of the quality of life and social relationship.

    Evidence of Norway's position as a world leader in terms of design and construction of hydroelectric power plant, and its position as the biggest producer of hydro in Europe, is presented. There is still some 30 TWh of hydro available for development in Norway. Statkraft is the country's biggest hydro generator: it owns and operates 54 hydro plants and has shares in a further 30. Statkraft's research has shown that there is still a large market for renewables in Europe and believes that householders are prepared to pay a premium for green energy. Statkraft trades energy with Denmark and Sweden and is believed to be planning further growth overseas. The new millennium is set to bring major changes in Norway's power industry: Hafslund and Elkem have already agreed to merge to create the country's biggest privately-owned power group

    2008-03-01

    Hydroelectric power is a predictable renewable energy source that produces no greenhouse gases (GHGs) and has low maintenance costs. In addition to river resources, low head hydro is available in sluice gates, irrigation canals, drinking water pressure release valves, and municipal wastewater outfalls. Canada's potential for low head hydro has been estimated at 5000 MW at 2000 different sites across the country. Sites of up to 50 MW have been identified in Ontario and Manitoba. This study performed a market assessment on low head hydro developments. Available and emerging technologies for developing low head hydro were identified. The economics of low head hydro in Canada were explored, and barriers to low head hydro development were identified. Strategies to promote low head hydro development were also explored, and the impact of different incentive types on the low head hydropower market were estimated using a simple economic model. It was concluded that a reduced, streamlined, and standardized environmental assessment process will significantly benefit low head hydro development in Canada. 5 refs., 14 tabs., 17 figs

Follow-up mutagenesis experiments targeting the predicted active site residues validate the oligomeric model and determined that each of the tested residues are essential for Spa47 ATPase activity, although they are not directly responsible for stable oligomer formation. Although N-terminal domain truncation was necessary for crystal formation, it resulted in strictly monomeric Spa47 that is unable to hydrolyze ATP, despite maintaining the canonical ATPase core structure and active site residues. Coupled with studies of ATPase inactive full-length Spa47 point mutants, we find that Spa47 oligomerization and ATP hydrolysis are needed for complete T3SS apparatus formation, a proper translocator secretion profile, and Shigella virulence. This work represents the first structure-function characterization of Spa47, uniquely complementing the multitude of included Shigella T3SS phenotype assays and providing a more complete understanding of T3SS ATPase-mediated pathogen virulence. Additionally, these findings provide a strong platform for follow-up studies evaluating regulation of Spa47 oligomerization in vivo as a much needed means of treating and perhaps preventing shigellosis. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

    The recent introduction of Hydro-Quebec, the Canadian utility, into selling cheap electric power in the United States (US) deregulated power market is described, following applications to the US Federal Energy Regulatory Commission. As its prices are so much cheaper than its US competitors, it is expected that the company will soon have many willing customers across the USA. Hydro-Quebec will remain a publicly owned utility, but has experienced restructuring in order to meet this new competitive challenge. (UK)

    The pros and cons of the potential privatisation of Hydro-Quebec were discussed. A brief review of charges of less than competent management, low profitability and the corporation's recent administrative restructuring was presented. The general thrust of the argument was that Hydro-Quebec plays a crucial role in the economic development of Quebec, it can be made to be more profitable and that for the good of Quebec it should continue as a public corporation under the control of the provincial government

    The government in Peru has decided to utilise its gas reserves and restrict hydro to relatively small schemes. A number of reasons for the decision are given. In 1997, the Shell-Mobile-Bechtel-COSAPI consortium was formed and agreements were signed regarding exploiting Gas de Camisea. The country's energy needs to 2010 are being assessed. It is likely that by 2001 the whole of south Peru will be receiving gas from Camisea. The Peru situation is discussed under the headings of (i) existing capacity, (ii) growing demands, (iii) a history of hydro in Peru, (iv) electrification and SHP and (v) outlook. The future for Peru's electric energy development is bright. While most of its new power capacity will come from natural gas, the small hydros also have a part to play. A stronger commitment of national and regional political authorities to consider supplies outside the big cities is said to be needed. (UK)

    Hydro power is one of the most flexible sources of electricity production. Power systems with considerable amounts of flexible hydro power potentially offer easier integration of variable generation, e.g., wind and solar. However, there exist operational constraints to ensure mid-/long-term security of supply while keeping river flows and reservoirs levels within permitted limits. In order to properly assess the effective available hydro power flexibility and its value for storage, a detailed assessment of hydro power is essential. Due to the inherent uncertainty of the weather-dependent hydrological cycle, regulation constraints on the hydro system, and uncertainty of internal load as well as variable generation (wind and solar), this assessment is complex. Hence, it requires proper modeling of all the underlying interactions between hydro power and the power system, with a large share of other variable renewables. A summary of existing experience of wind integration in hydro-dominated power systems clearly points to strict simulation methodologies. Recommendations include requirements for techno-economic models to correctly assess strategies for hydro power and pumped storage dispatch. These models are based not only on seasonal water inflow variations but also on variable generation, and all these are in time horizons from very short term up to multiple years, depending on the studied system. Another important recommendation is to include a geographically detailed description of hydro power systems, rivers' flows, and reservoirs as well as grid topology and congestion.

    In most European countries, balneotherapy and spa therapy are widely prescribed by physicians and preferred by European citizens for the treatment of musculoskeletal problems including chronic low back pain (LBP). We aimed to review and evaluate the recent evidence on the effectiveness of balneotherapy and spa therapy for patients with LBP. We comprehensively searched data bases for randomized controlled trials (RCTs) published in English between July 2005 and December 2013. We identified all trials testing balneotherapy or spa therapy for LBP that reported that the sequence of allocation was randomized. We finally included total of eight RCTs: two on balneotherapy and six on spa therapy. All reviewed trials reported that balneotherapy was superior in long term to tap water therapy in relieving pain and improving function and that spa therapy combining balneotherapy with mud pack therapy and/or exercise therapy, physiotherapy, and/or education was effective in the management of low back pain and superior or equally effective to the control treatments in short and long terms. We used Jadad scale to grade the methodological quality. Only three out of total eight had a score of above 3 indicating the good quality. The data from the RCTs indicates that overall evidence on effectiveness of balneotherapy and spa therapy in LBP is encouraging and reflects the consistency of previous evidence. However, the overall quality of trials is generally low. Better quality RCTs (well designed, conducted, and reported) are needed testing short- and long-term effects for relieving chronic back pain and proving broader beneficial effects.

    A critique of current management and personnel problems at Hydro-Quebec was presented. With 20,000 employees and some of the world's greatest hydroelectric projects to its credit, Hydro-Quebec has historically been a source of great pride for its employees and Quebec's society. However, recent problems related to management, bureaucratization and communications within the corporation have led to important moral problems within the workforce. Management of the corporation under the newly appointed president, Andre Caille, the issue of profitability and competitiveness, the worsening morale among employees and the relationship between Hydro-Quebec and the provincial government were the principal topics discussed

  12. Innovative private micro-hydro power development in Rwanda

    Pigaht, Maurice; Plas, Robert J. van der

    2009-01-01

    Under the 'Private Sector Participation in Micro-Hydro Development Project in Rwanda', four newly registered Rwandan companies are each constructing a micro-hydro electricity plant (100-500 kW) and building a low-voltage distribution grid. These companies financed their plants through their own equity and debt with support from the PSP Hydro project. This support comprised a subsidy of 30-50% of investment costs, technical and business development assistance, project monitoring and financial controlling. The experiences gained so far have important implications for similar future micro-hydro energy sector development projects and this paper puts forward three key messages: (i) institutional arrangements rather than technical quality determine the success of such projects; (ii) truly sustainable rural electrification through micro-hydro development demands a high level of local participation at all levels and throughout all project phases, not just after plant commissioning; and (iii) real impact and sustainability can be obtained through close collaboration of local private and financial sector firms requiring only limited external funds. In short, micro-hydro projects can and will be taken up by local investors as a business if the conditions are right. Applying these messages could result in an accelerated uptake of viable micro-hydro activities in Rwanda, and in the opinion of the authors elsewhere too.

    Ontario Hydro is developing an integrated air management plan as a tool for comparing the environmental impacts of fossil-fuel power generation options. The goal is to relate equipment, location, emissions, and impacts and to identify the optimum way to manage the utility's fossil generation system in view of upcoming environmental regulations and public expectations. The eight steps of the plan are briefly described: definition of power generation scenarios (upgrading, conversion to natural gas, non-utility generation, alternative technologies); estimation of emissions for each generation and fuel option studied; identification of impact of air emissions on building materials, agriculture, forests, lakes, and fisheries; modelling of air emissions dispersion; quantification of damage to pollution receptors; quantification of full fuel cycle effects; and comparison of the scenarios. The scenario having the lowest overall environmental impact involved upgrading the existing fossil-fuel system with additional air emissions controls and two integrated gasification combined cycle plants. 9 refs., 3 figs., 3 tabs

    2008-01-01

    BC Hydro like many other hydro utilities has used the historical record of weather and runoff as the standard description the variability and uncertainty of the key weather drivers for its operation and planning studies. It has been conveniently assumed that this historical record is or has been statistically stationary and therefore is assumed to represent the future characteristics of climatic drivers on our system. This assumption is obviously no longer justifiable. To address the characterisation of future weather, BC Hydro has a multi-year a directed research program with the Pacific Climate Impacts Consortium to evaluate the impacts of climate change on the water resources that BC Hydro manages for hydropower generation and other uses. The objective of this program is to derive climate change adjusted meteorologic and hydrologic sequences suitable for use in system operations and planning studies. These climate-adjusted sequences then can be used to test system sensitivity to climate change scenarios relative to the baseline of the historical record. This paper describes BC Hydro's research program and the results achieved so far. (author)

    2017-10-01

    Hydrotherapy equipment provides a perfect environment for the formation and growth of microbial biofilms. Biofilms may reduce the microbiological cleanliness of hydrotherapy equipment and harbour opportunistic pathogens and pathogenic bacteria. The aims of this study were to investigate the ability of microorganisms that colonize hydrotherapy equipment to form biofilms, and to assess the influence of temperature and nutrients on the rate of biofilm formation. Surface swab samples were collected from the whirlpool baths, inhalation equipment and submerged surfaces of a brine pool at the spa center in Ciechocinek, Poland. We isolated and identified microorganisms from the swab samples and measured their ability to form biofilms. Biofilm formation was observed at a range of temperatures, in both nutrient-deficient and nutrient-rich environments. We isolated and identified microorganisms which are known to form biofilms on medical devices (e.g. Stenotrophomonas maltophilia). All isolates were classified as opportunistic pathogens, which can cause infections in humans with weakened immunity systems. All isolates showed the ability to form biofilms in the laboratory conditions. The potential for biofilm formation was higher in the presence of added nutrients. In addition, the hydrolytic activity of the biofilm was connected with the presence of nutrients.

    To determine whether spa therapy has a beneficial effect on pain and disability in patients with chronic shoulder pain, this single-blind randomised controlled clinical trial included patients with chronic shoulder pain due to miscellaneous conditions attending one of four spa centres as outpatients. Patients were randomised into two groups: spa therapy (18 days of standardised treatment combining thermal therapy together with supervised mobilisation in a thermal pool) and controls (spa therapy delayed for 6 months: `immediate versus delayed treatment' paradigm). All patients continued usual treatments during the 6-month follow-up period. The main endpoint was the mean change in the French-Quick DASH (F-QD) score at 6 months. The effect size of spa therapy was calculated, and the proportion of patients reaching minimal clinically important improvement (MCII) was compared. Secondary endpoints were the mean change in SF-36, treatment use and tolerance. One hundred eighty-six patients were included (94 patients as controls, 92 in the spa group) and analysed by intention to treat. At 6 months, the mean change in the F-QD score was statistically significantly greater among spa therapy patients than controls (- 32.6 versus - 8.15%; p < 0.001) with an effect size of 1.32 (95%CI: 0.97-1.68). A significantly greater proportion of spa therapy patients reached MCII (59.3 versus 17.9%). Spa therapy was well tolerated with a significant impact on SF-36 components but not on drug intake. Spa therapy provided a statistically significant benefit on pain, function and quality of life in patients with chronic shoulder pain after 6 months compared with usual care.

    The prospects for development of hydro in the Himalayas has been enhanced by privatisation and the urgent need for clean electricity in the north of India. There are various hurdles to be overcome before the projects are likely to move forward in earnest before 2005, and these are mentioned. The demand for electricity in India is said to be enormous. At present, there is much polluting industry along the Himalayas. As throughout the Indian privatisation dilemma, the critical issues for development of Himalayan hydro come down to credible commercial power markets and finance. With regard to finance and administrative changes, the Indian government is carrying out a number of actions and these are itemised. The US is vigorously promoting the development of Himalayan hydro as a key to much needed regional co-operation and the World Bank is supportive

    Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of bacteraemia. We aimed to obtain a complete picture of severe MRSA infections by characterizing all MRSA isolates from bloodstream infections in the largest German federal state (North Rhine-Westphalia, 18 million inhabitants) using S. aureus protein A (spa) sequence-typing and antimicrobial susceptibility testing. MRSA isolates (n = 1952) were collected prospectively (2011-2013) and spa-typed. Among 181 different spa types, t003 (n = 746 isolates; 38.2%) and t032 (n = 594; 30.4%) were predominant. Analysis of the geographical occurrence of spa clonal complexes (spa-CCs) and spa types revealed divergent distribution between federal state districts for spa-CCs 003 (p resistant to fluoroquinolones, 78% to erythromycin, 70% to clindamycin, 4% to gentamicin, 2% to rifampicin, 0.4% to daptomycin, 0.1% to linezolid and 0% to vancomycin, respectively. Vancomycin MICs of 2 mg/L involved 0.5% of the isolates. In conclusion, the detection of regional molecular clusters added valuable information for epidemiological case tracing and allowed conclusions to be reached on the importance of newly emerging MRSA reservoirs, such as livestock (spa-CC011), for MRSA bacteraemia in some parts of the federal state. Susceptibility testing revealed broad resistance to substances used for oral treatment, but demonstrated that those antibiotics that are mostly applied for treatment of MRSA bacteraemia and important combination partners were highly susceptible.

    Full Text Available As intermittent renewable energy is receiving increasing attention, the combination of intermittent renewable energy with large-scale energy storage technology is considered as an important technological approach for the wider application of wind power and solar energy. Pumped hydro combined with compressed air energy storage system (PHCA is one of the energy storage systems that not only integrates the advantages but also overcomes the disadvantages of compressed air energy storage (CAES systems and pumped hydro energy storage systems to solve the problem of energy storage in China’s arid regions. Aiming at the variable working conditions of PHCA system technology, this study proposes a new constant-pressure PHCA. The most significant characteristics of this system were that the water pump and hydroturbine work under stable conditions and this improves the working efficiency of the equipment without incurring an energy loss. In addition, the constant-pressure PHCA system was subjected to energy and exergy analysis, in expectation of exploring an attractive solution for the large-scale storage of existing intermittent renewable energy.

  9. CDM pilot project to stimulate market for family-hydro for low-income households

    International Nuclear Information System (INIS)

    2004-01-01

    Over 100,000 low-income households living in rural, rice-farming regions of Vietnam and China rely upon family-hydro (between 100 and 200W) as the only affordable means of obtaining electricity. These systems are used for domestic lighting, radio and, in some cases, televisions. The units are small, cheap and are usually installed and owned by a single family. Funding from the CDM could be utilised in order to reduce the cost of good quality equipment to provide low-income households living in isolated off-grid locations with an affordable and sustainable electricity supply which can meet their needs for lighting, educational, productive and recreational uses. Therefore research was needed to determine the level of carbon emission reductions resulting from their use. The successful acceptance by the Prototype Carbon Fund (PCF) of the methodology of establishing the benchmark developed during this project could then be used as a precedent by other project developers in the future, thus being of long-term support to the emerging family-hydro industry.

    1995-01-01

    Lubricant analysis has always played an important yet somewhat invisible role in equipment health monitoring. At its most primitive, simple observations and field testing alert equipment operators to changing conditions. At its most advanced, data from performance and analytical tests are used to develop or select optimum lubricants for service, stretch drain intervals, predict remaining equipment life and identify potential equipment or system problems at an incipient stage. Coupled with thermography and vibration analysis, lubricant analysis can become a major component of a comprehensive predictive maintenance (PM) program. Ontario Hydro finds itself at a turning point regarding the use and monitoring of lubricants. Increasing emphasis on equipment reliability and plant life extension, coupled with major, recent changes in lubricant composition in response to environmental, energy and safety concerns, forces an upgrading of many aspects of lubricant monitoring so that it may establish itself as a key part of modern PM practices. This paper discusses some of these aspects. (author)

    The hydraulic energy could be easily developed in France to reach the objectives of the european directive on the renewable energies. This development can be assured by the construction of power plants perfectly integrated in their environment and respecting the rivers and assured also by the increase of the capacities of existing power plants as it is allowing by the new regulations. This document presents the place and the capacity of the hydro-electricity in France, the implementing of a green electricity, the existing regulation, the river biological continuation, the ecosystems and the little hydro-electricity and the example of the hydro-electric power plant of Scey-sur-Saone.

    Hydro-carbon molecules are abundantly produced when graphites are used as internal wall materials of hydrogen plasmas and strongly influence properties of low temperature plasmas near the edges as well as those of high temperature plasmas at the center. In this report, following simple description of the production mechanisms of hydro-carbon molecules under the interactions between graphite and hydrogen plasma, the present status of collision data for hydro-carbon molecules by electron impact is discussed and the relevant data are summarized in a series of figures and tables. It should also be noted that, in addition to fusion plasmas, these hydrocarbon data compiled here are quite useful in other applications such as plasma chemistry and material processing. (author)

    To determine whether spa therapy has a beneficial effect on pain and disability in patients with chronic shoulder pain, this single-blind randomised controlled clinical trial included patients with chronic shoulder pain due to miscellaneous conditions attending one of four spa centres as outpatients. Patients were randomised into two groups: spa therapy (18 days of standardised treatment combining thermal therapy together with supervised mobilisation in a thermal pool) and controls (spa therapy delayed for 6 months: `immediate versus delayed treatment' paradigm). All patients continued usual treatments during the 6-month follow-up period. The main endpoint was the mean change in the French-Quick DASH (F-QD) score at 6 months. The effect size of spa therapy was calculated, and the proportion of patients reaching minimal clinically important improvement (MCII) was compared. Secondary endpoints were the mean change in SF-36, treatment use and tolerance. One hundred eighty-six patients were included (94 patients as controls, 92 in the spa group) and analysed by intention to treat. At 6 months, the mean change in the F-QD score was statistically significantly greater among spa therapy patients than controls (- 32.6 versus - 8.15%; p impact on SF-36 components but not on drug intake. Spa therapy provided a statistically significant benefit on pain, function and quality of life in patients with chronic shoulder pain after 6 months compared with usual care.

  20. BC Hydro shops for GHG offsets

    2000-01-01

    BC Hydro is reported to have offered to purchase one million tonnes of carbon dioxide reductions in Canada's Greenhouse Gas Emissions Reduction Trading program (GERT). The program uses a baseline and credit system, where emitters purchase measurable quantities of site-specific GHG reductions. Since mid-1998, the program registered five bilateral trades and seven offers to sell. BC Hydro's recent offer is the first offer to buy. BC Hydro has made the offer to buy in expectation of the introduction of the start of the Kyoto Protocol reductions, and expects to be in the game for some time to come if it is to meet its obligations under the Kyoto Protocol. Preference will be given to projects located in Canada, but BC Hydro will consider reductions created anywhere in the world. The financial range of a single trade is between $50,000 and $1 million. (GHG offsets are currently trading in North America for between $.50 and $3.00 Cdn per metric tonne of carbon dioxide equivalent.) At present, offsets are selling at a heavily discounted price because of the uncertainty that investments made now will be credited against future regulations curbing emitters. Consequently, buying now while prices are low, may lead to sizable benefits later, depending on the actual regulations when they are promulgated. Trading now will also give BC Hydro greater credibility and assurance to have its voice heard when discussions about emissions trading and the implementation of emission trading rules reaches the serious stage

    Hydro-Quebec''s advance into the North American and world multi-energy market began with the purchase of an interest in the natural gas holding company Noverco, a commercial partnership with Gaz de France, and marketing agreements with Enron and Trigen in the United States. Hydro-Quebec, the world''s sixth largest electric utility, aims to become a multi-energy enterprise selling not only electricity, but also natural gas, oil and certain renewable forms of energy. Currently, Hydro-Quebec is licensed to make border sales of electricity at regulated prices. Through the US Federal Energy Regulatory Commission (FERC), Hydro-Quebec will be able also to sell electricity through wholesale spot contracts with electricity marketers such as Trigen and Enron

  2. Enhanced discrimination of highly clonal ST22-methicillin-resistant Staphylococcus aureus IV isolates achieved by combining spa, dru, and pulsed-field gel electrophoresis typing data.

    ST22-methicillin-resistant Staphylococcus aureus type IV (ST22-MRSA-IV) is endemic in Irish hospitals and is designated antibiogram-resistogram type-pulsed-field group (AR-PFG) 06-01. Isolates of this highly clonal strain exhibit limited numbers of pulsed-field gel electrophoresis (PFGE) patterns and spa types. This study investigated whether combining PFGE and spa typing with DNA sequencing of the staphylococcal cassette chromosome mec element (SCCmec)-associated direct repeat unit (dru typing) would improve isolate discrimination. A total of 173 MRSA isolates recovered in one Irish hospital during periods in 2007 and 2008 were investigated using antibiogram-resistogram (AR), PFGE, spa, dru, and SCCmec typing. Isolates representative of each of the 17 pulsed-field group 01 (PFG-01) spa types identified underwent multilocus sequence typing, and all isolates were ST22. Ninety-seven percent of isolates (168 of 173) exhibited AR-PFG 06-01 or closely related AR patterns, and 163 of these isolates harbored SCCmec type IVh. The combination of PFGE, spa, and dru typing methods significantly improved discrimination of the 168 PFG-01 isolates, yielding 65 type combinations with a Simpson\\'s index of diversity (SID) of 96.53, compared to (i) pairwise combinations of spa and dru typing, spa and PFGE typing, and dru and PFGE typing, which yielded 37, 44, and 43 type combinations with SIDs of 90.84, 91.00, and 93.57, respectively, or (ii) individual spa, dru, and PFGE typing methods, which yielded 17, 17, and 21 types with SIDs of 66.9, 77.83, and 81.34, respectively. Analysis of epidemiological information for a subset of PFG-01 isolates validated the relationships inferred using combined PFGE, spa, and dru typing data. This approach significantly enhances discrimination of ST22-MRSA-IV isolates and could be applied to epidemiological investigations of other highly clonal MRSA strains.

    Degenerative joints and disc disease is accompanied by chronic pain which is the main symptom of the disease. Medical spa therapy has the task of providing comprehensive treatment embracing diseases of limbs as well as other systems and the essential role of medical treatment, in particular spa therapy, is pain relief. The aim of the study was to evaluate the effect of the spa treatment on the level of pain perception in patients with degenerative joints and disc disease. The observation embraced 120 people with degenerative joints and disc disease treated in the spa. The study included a comprehensive therapy conducted over a 21-day stays at the spa Przerzeczyn-Zdrój with the application of selected physical treatments, physiotherapy and the use of therapeutic natural resources: peloid mud and healing radon-sulphide water. Moreover, there was psychological counseling and health education conducted. The study also included observation of 21 persons from the control group. However, the patients in the control group did not benefit from balneotherapy, psychological care and education. There was a standard VAS scale for pain and non-standard questionnaire of pain assessment constructed for the study purposes. The assessment of pain using the VAS scale and questionnaire of pain assessment both in the study group and the control group were performed before and after the treatment. The results were analyzed statistically, there was Statistica program in Polish version used. In the analysis of the obtained results there were two tests scheduled: the sign test, the Wilcoxon test and descriptive statistics. As a result of the spa therapy and treatments administered on an outpatient basis there was reduction of pain intensity observed. 1. Spa therapy and outpatient treatment reduce the level of pain in patients with degenerative joints and disc disease. 2. The reduction of pain level was more effective in case of therapy conducted in the spa.

    The Hydrological data and maps based on SHuttle Elevation Derivatives at multiple Scales (HydroSHEDS) is an innovative product that, for the first time, provides hydrographic information in a consistent and comprehensive format for regional and global-scale applications. HydroSHEDS offers a suite of geo-referenced data sets, including stream networks, watershed boundaries, drainage directions, and ancillary data layers such as flow accumulations, distances, and river topology information. The goal of developing HydroSHEDS was to generate key data layers to support regional and global watershed analyses, hydrological modeling, and freshwater conservation planning at a quality, resolution and extent that had previously been unachievable. Available resolutions range from 3 arc-second (approx. 90 meters at the equator) to 5 minute (approx. 10 km at the equator) with seamless near-global extent. HydroSHEDS is derived from elevation data of the Shuttle Radar Topography Mission (SRTM) at 3 arc-second resolution. The original SRTM data have been hydrologically conditioned using a sequence of automated procedures. Existing methods of data improvement and newly developed algorithms have been applied, including void filling, filtering, stream burning, and upscaling techniques. Manual corrections were made where necessary. Preliminary quality assessments indicate that the accuracy of HydroSHEDS significantly exceeds that of existing global watershed and river maps. HydroSHEDS was developed by the Conservation Science Program of the World Wildlife Fund (WWF) in partnership with the U.S. Geological Survey (USGS), the International Centre for Tropical Agriculture (CIAT), The Nature Conservancy (TNC), and the Center for Environmental Systems Research (CESR) of the University of Kassel, Germany.

    Although India has approximately 150,000 megawatts of hydro potential, only a small portion is tapped. There is also significant untapped hydro potential in many developing countries such as Nepal, Bhutan, Vietnam, Indonesia and regions in South America and Africa. Small-scale hydroelectric power systems with capacities of up to a few megawatts are eco-friendly and sustainable. They can be classified based on unit sizes as pico (u pto 10 kilowatts), micro (10-100 kilowatts) and mini (100 kilowatts to a few megawatts) hydro systems. Mini hydro systems are always grid connected while micro can be either grid connected or off grid. Pico is always off grid. In India, there are thousands of favorable sites in this range that should be tapped for distributed power generation to electrify local communities. This need is reflected by the global emphasis on distributed power generation as well as the Government of India's policy to promote this type of power generation. A working stand alone pico-hydro power generating system has been successfully installed in 5 sites in Karnataka. The purpose of the project was to demonstrate the technical, managerial and economic feasibility of setting up small hydro projects in remote hilly areas of Karnataka, India and its positive environmental impact. The presentation discussed the site selection criteria; installed sites of pico hydro; system description; parts of the system; the electric load controller; types of electronic load controllers; and a description of the unit and control scheme. tabs., figs.

    The South Pole Aitken (SPA) basin is the stratigraphically oldest identifiable lunar basin and is therefore one of the most important targets for absolute age-dating to help understand whether ancient lunar bombardment history smoothly declined or was punctuated by a cataclysm. A feasible near-term approach to this problem is to robotically collect a sample from near the center of the basin, where vertical and lateral mixing provided by post-basin impacts ensures that such a sample will be composed of small rock fragments from SPA itself, from local impact craters, and from faraway giant basins. The range of ages, intermediate spikes in the age distribution, and the oldest ages are all part of the definition of the absolute age and impact history recorded within the SPA basin.

    The objective of this study is to determine the use and efficacy of spa therapy in patients with a wide spectrum of rheumatic and musculoskeletal diseases under real-life clinical practice circumstances. In this retrospective observational study at the Medical Ecology and Hydroclimatology Department of Istanbul Faculty of Medicine, the records of all adult patients with rheumatic and musculoskeletal diseases who were prescribed a spa therapy in various health resorts in Turkey between 2002 and 2012 were analyzed. Patients sojourned to and stayed at a health resort and followed a usual 2-week course of spa therapy. The patients were examined within a week before and after the spa therapy at the department by the physicians and outcome measures were pain intensity (visual analog scale, VAS), patient's general evaluation (VAS), physician's general evaluation (VAS), Health Assessment Questionnaire (HAQ), Lequesne's Functional Index (LFI), Western Ontario and McMaster Universities Index (WOMAC), Waddell Index (WI), Neck Pain and Disability Scale (NPDS), Shoulder Disability Questionnaire (SDQ), Fibromyalgia Impact Questionnaire (FIQ), and Beck's Depression Inventory (BDI). In total, 819 patients were included in the analysis. The diagnoses were 536 osteoarthritis; 115 fibromyalgia; 50 lumbar disc herniation; 34 cervical disc herniation; 23 nonspecific low back pain; 22 ankylosing spondylitis; 16 rheumatoid arthritis; 9 rotator cuff tendinitis; and 14 other conditions/diseases including scoliosis, stenosing flexor tenosynovitis, congenital hip dislocation in adult, Behçet's disease, de Quervain tendinopathy, psoriatic arthritis, osteoporosis, fracture rehabilitation, and diffuse idiopathic skeletal hyperostosis.

    Treatment of psoriasis is very complex and there are no still universal, nor unique treatment modalities. Apart from conventional treatment, which includes topical calcipotriol (vitamin D3 analogue), balneotherapy is drawing increased attention worldwide. Being part of climatotherapy, balneotherapy is defined as the use of natural environmental factors in the treatment of health conditions, whereas in the treatment of psoriasis it means the use of mineral baths and peloids. The aim of this study was to examine the therapeutic efficacy of mineral waters and peloids of the Rusanda Spa on plaque psoriasis in patients also treated with calcipotriol. The study included 60 patients divided into two groups. The first group included patients treated with mineral waters, peloids and calcipotriol in the Rusanda Spa, while the second one included those treated only with calcipotriol. The study took 21 days, and each patient was followed up for at least one month after ending the treatment. The treatment efficacy was measured by psoriasis area severity index (PASI) scores on the days 0, 7, 14 and 21 during the treatment and 30 after the end of the therapy. After a 3-week treatment in the Rusanda Spa, the first group showed a decrease in PASI score by 59.45%, whereas in the group of outpatients treated by calcipotriol it was 39.34%. On the day 30 following the treatment, the first group presented with the PASI score reduction of 58.44%, and the second group of 34.78%. The therapeutic efficacy of mineral waters and peloids combined with calcipotriol showed to be significantly higher in regard to monotherapy with calcipotriol (p balneotherapy as monotherapy in treatment of this type of psoriasis.

  11. IPPSO raises Hydro exports in smog negotiations

    1997-01-01

    The Independent Power Producers of Ontario (IPPSO) requested federal and provincial committees negotiating atmospheric emission standards to review Ontario Hydro's export wheeling plans. IPPSO alleges that Ontario Hydro is preparing to apply pressure on the Canadian export approval process, and is building up a major effort that will increase emissions, contrary to the objectives embodied in a number of environment protection projects such as the Ontario Smog Plan, The Federal-Provincial NOx Management Plan, the Strategic Options Plan, or the Convention on Long-Range Transboundary Air Pollution Draft NOx Protocol Negotiations. IPPSO alleges further that while Ontario Hydro is one of Canada's largest single emitter of greenhouse gases NOx, and SO 2 , and as a public sector corporation it should be the most amenable to serving the public good, the Corporation is doing exactly the opposite: it actively prevents production of electricity from less polluting sources. It is IPPSO's contention that Ontario Hydro's desire to control the Ontario market could come at significant cost to the environment

    The operational National Water Model (NWM), implemented in August 2016, is an instantiation of the Weather Research and Forecasting hydrological extension package (WRF-Hydro). Currently, the NWM only covers the contiguous United States, but will be expanded to include an Alaska domain in the future. It is well known that Alaska presents several hydrological modeling challenges, including unique arctic/sub-arctic hydrological processes not observed elsewhere in the United States and a severe lack of in-situ observations for model initialization. This project sets up an experimental version of WRF-Hydro in Alaska mimicking the NWM to gauge the ability of WRF-Hydro to represent hydrological processes in Alaska and identify model calibration challenges. Recent and upcoming launches of hydrology-focused NASA satellite missions such as the Soil Moisture Active Passive (SMAP) and Surface Water Ocean Topography (SWOT) expand the spatial and temporal coverage of observations in Alaska, so this study also lays the groundwork for assimilating these NASA datasets into WRF-Hydro in the future.

  13. Canadian hydro potential in the North American market

    Adams, K.

    2002-01-01

    Canada's hydro potential in the North American energy market was discussed. Canada is a net exporter of electricity in North America, and since 1990, has exported an average of 28 Terawatt hours/year to the United States. More than 65 per cent of these exports were generated from hydro power plants. It was emphasized that significant reductions in greenhouse gases can be achieved if Canadian hydroelectricity is substituted for coal power generation. It was also noted that although there may not be enough hydro capacity to meet all of North America's energy requirements, development of new large hydro resources in Canada could help meet the growing demand for electricity in the United States. Hydro can also complement other renewable energy sources such as wind and solar. The factors that will determine if Canadian hydropower will contribute to the energy demand are market mechanisms such as greenhouse gas credit trading systems which provide incentive for renewable energy projects. In addition, the existing infrastructure must be expanded both east and west within Canada and north and south between Canada and the United States. 5 figs

  14. Genomic and Functional Characterization of the Unusual pLOCK 0919 Plasmid Harboring the spaCBA Pili Cluster in Lactobacillus casei LOCK 0919

    2016-01-01

    Here, we report the extensive bioinformatic and functional analyses of the unusual pLOCK 0919, a plasmid originating from the probiotic Lactobacillus casei LOCK 0919 strain. This plasmid is atypical because it harbors the spaCBA-srtC gene cluster encoding SpaCBA pili. We show that all other spaCBA-srtC sequences of the Lactobacillus genus that have been previously described and deposited in GenBank are present in the chromosomal DNA. Another important observation for pLOCK 0919 is that the spaCBA-srtC gene cluster and its surrounding genes are highly similar to the respective DNA region that is present in the most well-known and active SpaCBA pili producer, the probiotic Lactobacillus rhamnosus GG strain. Our results demonstrate that the spaCBA-srtC clusters of pLOCK 0919 and L. rhamnosus GG are genealogically similar, located in DNA regions that are rich in transposase genes and are poorly conserved among the publicly available sequences of Lactobacillus sp. In contrast to chromosomally localized pilus gene clusters from L. casei and Lactobacillus paracasei, the plasmidic spaC of L. casei LOCK 0919 is expressed and undergoes a slight glucose-induced repression. Moreover, results of series of in vitro tests demonstrate that L. casei LOCK 0919 has an adhesion potential, which is largely determined by the presence of the pLOCK 0919 plasmid. In particular, the plasmid occurrence positively influenced the hydrophobicity and aggregation abilities of L. casei LOCK 0919. Moreover, in vivo studies indicate that among the three Lactobacillus strains used to colonize the gastrointestinal tract of germ-free mice, already after 2 days of colonization, L. casei LOCK 0919 became the dominant strain and persisted there for at least 48 days.

    The 'Elguea' spa, located in the north coast of the county of Villa Clara, Cuba, is considered one of those more important spas of Latin America. The waters of this spa are rich in salts of chlorine, sodium, bromine, sulfides and its contain radon. As a result of measurements of environmental gamma dose rates carried out in the area of the spa, its were considered levels of dose between 0.13 and 2.3 mSv. The obtained results motivated that it was carried out a characterization, from the radiological point of view, of the spa. This characterization is of supreme importance to be able to evaluate the impact that it has and the discharges of its waters on the environment, as well as, those dose that the population potentially affected can receive by these discharges. With this end its were carried out quantitative determinations of those existent natural more significant radionuclides in different environmental objects coming from the area of the spa and its surroundings, as well as one characterization gamma 'in situ' of the same one. The obtained results are present in this work. (Author)

    Full Text Available Investigations executed by the BNTU “Shipbuilding and hydraulics” department have shown that rather efficient implementation of the requirements to the metal sheet surface designed for laser cutting can be achieved by using hydro-abrasive jet cleaning while applying water pump equipment with the range of pressure – 20–40 MPa. Type of working fluid plays a significant role for obtaining surface of the required quality. The conducted experiments have demonstrated that the efficient solution of the assigned problems can be ensured by using a working fluid containing bentonite clay, surface-active agent polyacrylamide, soda ash and the rest water.

    Low back pain is a major public health concern and complementary treatments are frequently used for this condition. The objective of this systematic review and meta-analysis was to assess the evidence for or against the effectiveness of spa therapy and balneotherapy for treating low back pain. Systematic searches were conducted on Medline, Embase, Amed Cochrane Central, the UK National Research Register and ClincalTrials.gov (all until July 2005). Hand searches were performed and experts contacted. Methodological quality was assessed using a standard scale. Five randomized clinical trials met all inclusion criteria. Quantitative data synthesis was performed. The data for spa therapy, assessed on a 100 mm visual analogue scale (VAS), suggest significant beneficial effects compared with waiting list control groups (weighted mean difference 26.6 mm, 95% confidence interval 20.4-32.8, n=442) for patients with chronic low back pain. For balneotherapy the data, assessed on a 100 mm VAS, also suggest beneficial effects compared with control groups (weighted mean difference 18.8 mm, 95% confidence interval 10.3-27.3, n=138). Even though the data are scarce, there is encouraging evidence suggesting that spa therapy and balneotherapy may be effective for treating patients with low back pain. These data are not compelling but warrant rigorous large-scale trials.

    The CUAHSI Hydrologic Information System (HIS) is an internet based system that supports sharing of hydrologic data. HIS consists of databases connected using the Internet through Web services, as well as software for data discovery, access, and publication. The HIS system architecture is comprised of servers for publishing and sharing data, a centralized catalog to support cross server data discovery and a desktop client to access and analyze data. This paper focuses on HydroServer, the component developed for sharing and publishing space-time hydrologic datasets. A HydroServer is a computer server that contains a collection of databases, web services, tools, and software applications that allow data producers to store, publish, and manage the data from an experimental watershed or project site. HydroServer is designed to permit publication of data as part of a distributed national/international system, while still locally managing access to the data. We describe the HydroServer architecture and software stack, including tools for managing and publishing time series data for fixed point monitoring sites as well as spatially distributed, GIS datasets that describe a particular study area, watershed, or region. HydroServer adopts a standards based approach to data publication, relying on accepted and emerging standards for data storage and transfer. CUAHSI developed HydroServer code is free with community code development managed through the codeplex open source code repository and development system. There is some reliance on widely used commercial software for general purpose and standard data publication capability. The sharing of data in a common format is one way to stimulate interdisciplinary research and collaboration. It is anticipated that the growing, distributed network of HydroServers will facilitate cross-site comparisons and large scale studies that synthesize information from diverse settings, making the network as a whole greater than the sum of its

    We observed previously that newborn infants are colonized with Staphylococcus aureus, even if their mothers do not carry S aureus. This observation indicated a cross colonization, and, thus, a risk for nosocomial infection, although the infants are roomed in with their mothers. The S aureus colonization of infants, their parents, and staff members was measured at 3 maternity units. Possible transmission routes were determined using spa typing of S aureus isolates. Infants had the highest S aureus carriage (45%) compared with fathers (39%), mothers (27%), and staff members (27%). In 13 out of 44 colonized infants, transmission from staff members was indicated. This transmission was more frequent than was transmission from their own parents (11 cases), and occurred even in cases when parents were colonized with S aureus of other spa types. We confirm a high level of transmission of S aureus from staff members to infants, indicating a risk for patient safety, which necessitates continuing work with implementing scientific evidence for infection control. The spa typing is a rapid and valuable epidemiological tool, and it can be used in improving hospital hygiene control programs.

    Wounds that fail to heal quickly are often encountered by community nursing staff. An important step in assisting these chronic or stalled wounds progress through healing is debridement to remove devitalised tissue, including slough and eschar, that can prevent the wound from healing. A unique wound treatment called HydroTherapy aims to provide an optimal healing environment. The first step of HydroTherapy involves HydroClean plus™, this dressing enables removal of devitalised tissue through autolytic debridement and absorption of wound fluid. Irrigation and cleansing provided by Ringer's solution from the dressing further removes any necrotic tissue or eschar. Once effective wound bed preparation has been achieved a second dressing, HydroTac™, provides an ongoing hydrated wound environment that enables re-epithelialisation to occur in an unrestricted fashion. This paper presents 3 case studies of slow healing wounds treated with HydroClean plus™ which demonstrates effective wound debridement.

    Build-operate-transfer (BOT) schemes are the latest methods adopted in the developing infrastructure projects. This paper outlines the project financing through BOT schemes and briefly focuses on the factors particularly relevant to hydro power projects. Hydro power development provides not only the best way to produce electricity, it can also solve problems in different fields, such as navigation problems in case of run-of-the river plants, ground water management systems and flood control etc. This makes HPP projects not cheaper, but hydro energy is a clean and renewable energy and the hydro potential worldwide will play a major role to meet the increased demand in future. 5 figs

    Artificial intelligence (AI)-based software packages which can optimize power plant operations that improves heat rate and also reduces nitrogen oxide emissions are now commonly available for commercial use. This paper discusses the implementation of the AI-based NOx and Heat Rate Optimization System at Ontario Hydro`s generation stations, emphasizing the current AI Optimization Project at Units 5 and 6 of the Lakeview Generating Station. These demonstration programs are showing promising results in NOx reduction and plant performance improvement. The availability of the plant Digital Control System (DCS) in implementing AI optimization in a closed-loop system was shown to be an important criterion for success. Implementation of AI technology at other Ontario Hydro fossil generating units as part of the overall NOx emission reduction system is envisaged to coincide with the retrofit of the original plant control system with the latest DCS systems. 14 refs., 3 figs.

    In 1992 a program was initiated to establish reactor noise analysis as a practical tool for plant performance monitoring and system diagnostics in Ontario Hydro`s CANDU reactors. Since then, various CANDU-specific noise analysis applications have been developed and validated. The noise-based statistical techniques are being successfully applied as powerful troubleshooting and diagnostic tools to a wide variety of actual operational I and C problems. The dynamic characteristics of critical plant components, instrumentation and processes are monitored on a regular basis. Recent applications of noise analysis include (1) validating the dynamics of in-core flux detectors (ICFDS) and ion chambers, (2) estimating the prompt fraction ICFDs in noise measurements at full power and in power rundown tests, (3) identifying the cause of excessive signal fluctuations in certain flux detectors, (4) validating the dynamic coupling between liquid zone control signals, (5) detecting and monitoring mechanical vibrations of detector tubes induced by moderator flow, (6) estimating the dynamics and response time of RTD (Resistance Temperature Detector) temperature signals, (7) isolating the cause of RTD signal anomalies, (8) investigating the source of abnormal flow signal behaviour, (9) estimating the overall response time of flow and pressure signals, (10) detecting coolant boiling in fully instrumented fuel channels, (11) monitoring moderator circulation via temperature noise, and (12) predicting the performance of shut-off rods. Some of these applications are performed on an as-needed basis. The noise analysis program, in the Pickering-B station alone, has saved Ontario Hydro millions of dollars during its first three years. The results of the noise analysis program have been also reviewed by the regulator (Atomic Energy Control Board of Canada) with favorable results. The AECB have expressed interest in Ontario Hydro further exploiting the use of noise analysis technology. (author

    2013-12-01

    In the face of growing water demands, climate change and spatial and temporal water access variability, accurately assessing the economic impacts of proposed water resource management changes is useful. The objective of this project funded by UK Water Industry Research was to present and demonstrate a framework for identifying and using the ';value of water' to enable water utilities and their regulators to make better decisions. A hydro-economic model can help evaluate water management options in terms of their hydrological and economic impact at different locations throughout a catchment over time. In this talk we discuss three modes in which hydro-economic models can be implemented: evaluative, behavioral and prescriptive. In evaluation mode economic water demand and benefit functions are used to post-process water resource management model results to assess the economic impacts (over space and time) of a policy under consideration. In behavioral hydro-economic models users are represented as agents and the economics is used to help predict their actions. In prescriptive mode optimization is used to find the most economically efficient management actions such as allocation patterns or source selection. These three types of hydro-economic analysis are demonstrated on a UK watershed (Great River Ouse) that includes 97 different water abstractors from amongst the public water supply, agriculture, industry and energy plant cooling sectors. The following issues under dry and normal historical conditions were investigated: Supply/demand investment planning, societal cost of environmental flows, water market prices, and scarcity-sensitive charges for water rights. The talk discusses which hydro-economic modeling mode is used to study each of these issues and why; example results are shown and discussed. The topic of how hydro-economic models can be built and deployed effectively is covered along with how existing water utility operational and planning tools can be

    Energy utility companies must balance production from limited sources with increasing demand from industrial, business, and residential consumers. The utility planning process requires a balanced, efficient, and effective distribution of energy from source to consumer. Therefore utility planners must consider the impact of weather on energy production and consumption. Hydro-electric companies should be particularly tuned to weather because their source of energy is water, and water supply depends on precipitation. BC Hydro operates as the largest hydro-electric company in western Canada, managing over 30 reservoirs within the province of British Columbia, and generating electricity for 1.6 million people. BC Hydro relies on weather forecasts of watershed precipitation and temperature to drive hydrologic reservoir inflow models and of urban temperatures to meet energy demand requirements. Operations and planning specialists in the company rely on current, value-added weather forecasts for extreme high-inflow events, daily reservoir operations planning, and long-term water resource management. Weather plays a dominant role for BC Hydro financial planners in terms of sensitive economic responses. For example, a two percent change in hydropower generation, due in large part to annual precipitation patterns, results in an annual net change of \\50 million in earnings. A five percent change in temperature produces a \\5 million change in yearly earnings. On a daily basis, significant precipitation events or temperature extremes involve potential profit/loss decisions in the tens of thousands of dollars worth of power generation. These factors are in addition to environmental and societal costs that must be considered equally as part of a triple bottom line reporting structure. BC Hydro water resource managers require improved meteorological information from recent advancements in numerical weather prediction. At BC Hydro, methods of providing meteorological forecast data

    Spa2 is an important component of the multiprotein complex polarisome, which is involved in the establishment, maintenance, termination of polarized cell growth and is important for defining tip growth of filamentous fungi. In this study, we isolated an insertional mutant of the rice blast fungus Magnaporthe oryzae that formed smaller colony and conidia compared with the wild type. In the mutant, a spindle pole antigen gene MoSPA2 was disrupted by the integration of an exogenous plasmid. Targeted gene deletion and complementation assays demonstrated the gene disruption was responsible for the defects of the insertional mutant. Interestingly, the MoSpa2-GFP fusion protein was found to accumulate as a spot at hyphal tips, septa of hyphae and conidial tip cells where germ tubes are usually produced, but not in appressoria, infection hyphae or at the septa of conidia. Furthermore, the deletion mutants of MoSPA2 exhibited slower hyphal tip growth, more hyphal branches, and smaller size of conidial tip cells. However, MoSPA2 is not required for plant infection. These results indicate that MoSPA2 is required for vegetative hyphal growth and maintaining conidium morphology and that spotted accumulation of MoSpa2 is important for its functions during cell polar growth.

    Full Text Available Research results of hydro-cycloning of flocculated and non-flocculated flotation tailing from the lead and zinc open pit mine 'Suplja stijena', Sula - Montenegro have been shown in this paper. Reason for this research was finding conditions in order to separate fraction that is suitable for embankment erection. Flotation tailings has been tested in the very state that it goes out from the flotation process and tailings which is flocculated by anionic flocculant. The object was to determine the impact of flocculation on properties of hydro-cycloning products and disposal process. In hydro-cycloning process greater underflow mass is being separated with non-flocculated tailing. Values of geomechanical parameters are significantly different, especially hydro-cyclone's underflow. All geomechanical parameters of hydro-cyclone's underflow are suitable for erecting embankment which shall be made from non-flocculated tailing. Underflow drainage of non-flocculated tailing is faster while overflow drainage is slower and problematic with both tailings.

  18. Competition policy and regulation in hydro-dominated electricity markets

    International Nuclear Information System (INIS)

    Rangel, Luiz Fernando

    2008-01-01

    This paper discusses the main competition issues that arise in electricity systems dominated by hydro generation, arguing that technological differences between hydro and thermal plants may allow hydropower producers to exert market power in different and subtler ways compared to thermal generators. The key for market power in hydro-based systems is the strategic allocation of a given amount of output across periods, rather than a straightforward reduction of total output. The paper examines the interaction between strategic hydro reservoir operation and transmission capacity constraints, and summarizes the implications of market power for system reliability. A review of recent relevant literature is included. Finally, possible interventions to mitigate market power are analysed

    Nuclear utilities in recent years have focused on improved plant performance and equipment reliability. In U.S., there is a movement toward process integration. Examples are INPO AP-913 equipment reliability program and the standard nuclear performance model developed by NEI. Synergistic effect from an integrated approach can be far greater than as compared to individual effects from each program. In Korea, PSA for all Korean NPPs (Nuclear Power Plants) has been completed. Plant performance monitoring and improvement is an important goal for KHNP (Korea Hydro and Nuclear Power Company) and a risk monitoring system called RIMS has been developed for all nuclear plants. KHNP is in the process of voluntarily implementing maintenance rule program similar to that in U.S. In the future, KHNP would like to expand the effort to equipment reliability program and to achieve highest equipment reliability and improved plant performance. For improving equipment reliability, the current trend is moving toward preventive/predictive maintenance from corrective maintenance. With the emphasis on preventive maintenance, the failure cause and operation history and environment are important. Hence, the development of accurate reliability database is necessary. Furthermore, the database should be updated regularly and maintained as a living program to reflect the current status of equipment reliability. This paper examines the development of reliability database system and its application of maintenance optimization or Risk Informed Application (RIA). (authors)

    This chapter presents an overview of current hydro, ocean, wave and tidal initiatives. Large hydro remains one of the lowest-cost generating technologies, although environmental constraints, resettlement impacts and the limited availability of sites have restricted further growth in many countries. Large hydro supplied 16 % of global electricity in 2004, down from 19 % a decade ago. Large hydro capacity totalled about 720 GW worldwide in 2004 and has grown historically at slightly more than 2 % annually. China installed nearly 8 GW of large hydro in 2004, taking the country to number one in terms of installed capacity (74 GW). With the completion of the Three Gorges Dam, China will add some 18.2 GW of hydro capacity in 2009. The socio-economic benefits of hydro include improved flood control and water supply. The socio-economic benefits of hydro include improved flood control and water supply. The socio-economic cost of hydro includes displacements and submergence. Further hydro can improve peak-capacity management. Ocean currents, some of which runs close to European coasts, carry a lot of kinetic energy. Part of this energy can be captured by sub-marine windmills and converted into electricity. These are more compact than the wind turbines used on land, simply because water is much denser than air. The main European countries with useful current power potential are France and the UK. Ocean tides are driven by the gravitational pull of the moon. With one high tide every 12 hours, a tidal power plant can operate for only four or five hours per cycle, so power from a single plant is intermittent. A suitably-designed tidal plant can, however, operate as a pimped storage system, using electricity during periods of low demand to store energy that can be recovered later. The only large, modern example of a tidal power plant is the 240 MW La Rance plant, built in France in the 1960s, which represents 91 % of the world tidal power capacity. Wave energy can be seen as

    The various types of hydraulic turbines currently used in hydroelectric power plants are described. The descriptions are intended for use by non-engineers who are concerned with fish passage and fish mortality at a hydro power facility. Terminology used in the hydro industry is explained. Since the extent of cavitation is one of the factors affecting mortality rates of fish passing through hydraulic turbines, an equation is introduced which measures the extent of cavitation likely to be experienced in a turbine. An example of how the cavitation index can be calculated is provided for two typical power plants. The relation between certain parameters of power plant operation and the extent of cavitation, and therefore of fish mortality, is illustrated. 2 refs., 14 figs

    Architecture at Hydro-Quebec is concerned not only with combining function and aesthetics in designing buildings and other structures for an electrical utility, but also to satisfy technical and administrative needs and to help solve contemporary problems such as the rational use of energy. Examples are presented of Hydro-Quebec's architectural accomplishments in the design of hydroelectric power stations and their surrounding landscapes, thermal power stations, transmission substations, research and testing facilities, and administrative buildings. It is shown how some buildings are designed to adapt to local environments and to conserve energy. The utility's policy of conserving installations of historic value, such as certain pre-1930 power stations, is illustrated, and aspects of its general architectural policy are outlined. 20 figs.

    Geothermal waters contain, among other components, soluble radon gas. Alpha radioactive radon is a health hazard to humans, especially when it gets into the respiratory tract. SPA facilities that use geothermal water can be a source of an increased radiation dose to people who stay there. Based on the available literature concerning radon concentrations, we assessed exposure to radon among people - workers and visitors of Spa centers that use geothermal waters. Radon concentrations were analyzed in 17 geothermal centers: in Greece (3 centers), Iran (5), China (4) and India (5). Doses recived by people in the SPA were estimated using the formula that 1 hour exposure to 1 Bq/m3 of radon concentration and equilibrium factor F = 0.4 corresponds to an effective dose of 3.2 nSv. We have found that radon levels in SPAs are from a few to several times higher than those in confined spaces, where geothermal waters are not used (e.g., residential buildings). In 82% of the analyzed SPAs, workers may receive doses above 1 mSv/year. According to the relevant Polish regulations, people receiving doses higher than 1 mSv/year are included in category B of radiation exposure and require regular dosimetric monitoring. Doses received by SPA visitors are much lower because the time of their exposure to radon released from geothermal water is rather short. The analysis of radon concentration in SPA facilities shows that the radiological protection of people working with geothermal waters plays an important role. It seems reasonable to include SPA workers staying close to geotermal waters into a dosimetric monitoring program.

  5. Hydro-Quebec's buyback tariff

    Hydro-Quebec had an installed electric generation capacity of 25,682 MW in 1990, of which 23,927 MW was hydraulic. Of the 26 thermal power plants, 22 are in remote communities on islands or in the north part of the province. The utility's development plan predicts an annual growth in demand of 2.6% to reach ca 200 TWh in 2006; this demand would be reduced to ca 180 TWh by energy efficiency measures. To increase capacity, Hydro-Quebec can utilize the hydro generation potential of its large rivers, of which 18,000 MW is economically viable, and its small rivers. Of the 10,000 MW theoretical potential of the latter, a large fraction cannot be economically developed under existing conditions. The utility has a policy to purchase energy as a function of the price of fossil fuel. For wind energy, this price was 4.22 cents/kWh in 1991; this price will be increased annually according to the inflation index. In its isolated sites such as the Magdalen Islands, current costs of diesel-generated electricity are at least 5.5 cents/kWh. There are possibilities for installing wind plants in isolated regions but their automatic control systems need to be improved for achieving a larger utilization factor relative to diesel generation and their cost needs to be reduced. 1 tab

    Ontario Hydro, North America's largest electric power utility, with an installed capacity of 34,000 MW, has under gone a major restructuring over the past year to better align itself with a changing electricity market and evolving customer needs. The single largest new business unit within the new Ontario Hydro is Ontario Hydro Nuclear (OHN), responsible for engineering, operation and maintenance of the Corporation's 20 large nuclear units at three generating sites, OHN faces a significant challenge in returning Ontario's nuclear units to the world-leading performance levels they enjoyed in the past, particularly the older Pickering A and Bruce A plants. However, steady progress is being made as evidenced by improving peer reviews and overall capacity and financial performance

  8. The political economy of Canadian hydro-electricity : between old provincial hydros and neoliberal regional energy regimes

    2007-01-01

    In economic terms, hydro-electricity is considered as a quasi-staple, as it prone to the classic staples problem of excess capacity. However, neither water nor hydroelectricity in Canada is produced primarily for export markets. Hydroelectric systems are often thought of as politicized monopolies. This paper discussed changes that have occurred in hydroelectric organizations over time, as they have been governed by a formative mixed regime; postwar provincial hydro systems; a megaprojects regime; and an emerging sustainability regionalization regime. The origins of electricity generation and transmission in Canada were discussed, as well as the ecological footprint of large mega-projects on rivers. The development of provincial hydro monopolies during the mid- to late- twentieth century was also outlined, as well as the sustainability and regionalization regime that developed after 1990. During the mature staples period of the mid-century, rents in hydro-electric organizations were distributed through cheap rates to subsidize and facilitate the development of mass production and mass consumption. However, post-staples consumption has now replaced mass consumption, and demand side management is replacing earlier cheap power policies. Nonetheless, the lack of systematic integration of networks has led to inefficiencies. Provincial grids are now being integrated into interconnected North American regional networks regulated by the United States. It was concluded that the Canadian electricity regime is increasingly influenced by the the supranational role that the United States is playing in structuring markets. 83 refs

    Ontario Hydro has been producing electricity commercially from nuclear power since 1968, using CANDU reactors which have proved enormously successful. The 206-MW Douglas Point station, nearly 10 times larger than the first Canadian power reactor, NPD-2, resulted from a cooperative effort between Atomic Energy of Canada Ltd., the provincial government of Ontario, and Ontario Hydro. This approach led to a basic working relationship between the parties, with Ontario Hydro acting as project manager and builder, and AECL acting as consultant with respect to the nuclear components. Before Douglas Point was fully commissioned Ontario Hydro was ready to commit itself to more nuclear stations, and work was started on the four-unit Pickering nuclear generating station. Multi-unit stations were adopted to achieve economies of scale, and the concept has been retained for all subsequent nuclear power plants constructed in the province. The organization of Ontario Hydro's project management, construction, and operation of nuclear generating stations is described. Performance of the existing stations and cost of the power they produce have been entirely acceptable

    SpaA, one of the major pilins of C. diphtheriae, has been expressed, purified and crystallized and X-ray diffraction data have been collected to 1.6 Å resolution. Bacterial pili are cell-surface organelles that are critically involved in adhesion to host cells, leading to the colonization of host tissues and the establishment of infections. Whereas the pili of Gram-negative bacteria have been extensively studied, those of Gram-positive bacteria came to light only recently after the discovery and characterization of Corynebacterium diphtheriae pili. These newly discovered pili are formed by the covalent polymerization of pilin subunits catalyzed by sortase enzymes, making them fundamentally different from the noncovalent pilin assemblies of Gram-negative bacteria. Here, the expression, crystallization and preliminary crystallographic analysis of SpaA, which forms the shaft of one of the three types of pili expressed by C. diphtheriae, are reported. SpaA 53–486 crystals diffracted to 1.6 Å resolution and belonged to space group P2 1 2 1 2 1 , with unit-cell parameters a = 34.9, b = 64.1, c = 198.7 Å, α = β = γ = 90°

    Background Bacterial contact in utero modulates fetal and neonatal immune responses. Maternal probiotic supplementation reduces the risk of immune-mediated disease in the infant. We investigated the immunomodulatory properties of live Lactobacillus rhamnosus GG and its SpaC pilus adhesin in human fetal intestinal models. Methods TNF-α mRNA expression was measured by qPCR in a human fetal intestinal organ culture model exposed to live L. rhamnosus GG and proinflammatory stimuli. Binding of recombinant SpaC pilus protein to intestinal epithelial cells was assessed in human fetal intestinal organ culture and the human fetal intestinal epithelial cell line H4 by immunohistochemistry and immunofluorescence, respectively. TLR-related gene expression in fetal ileal organ culture after exposure to recombinant SpaC was assessed by qPCR. Results Live L. rhamnosus GG significantly attenuates pathogen-induced TNF-α mRNA expression in the human fetal gut. Recombinant SpaC protein was found to adhere to the fetal gut and to modulate varying levels of TLR-related gene expression. Conclusion The human fetal gut is responsive to luminal microbes. L. rhamnosus GG significantly attenuates fetal intestinal inflammatory responses to pathogenic bacteria. The L. rhamnosus GG pilus adhesin SpaC binds to immature human intestinal epithelial cells and directly modulates intestinal epithelial cell innate immune gene expression. PMID:25580735

    Highlights: • A two-stage distributionally robust hydro-thermal-wind model is proposed. • A semi-definite programing equivalent and its algorithm are developed. • Cases that demonstrate the effectiveness of the proposed model are included. - Abstract: With the penetration of wind energy increasing, uncertainty has become a major challenge in power system dispatch. Hydro power can change rapidly and is regarded as one promising complementary energy resource to mitigate wind power fluctuation. Joint scheduling of hydro, thermal, and wind energy is attracting more and more attention nowadays. This paper proposes a distributionally robust hydro-thermal-wind economic dispatch (DR-HTW-ED) method to enhance the flexibility and reliability of power system operation. In contrast to the traditional stochastic optimization (SO) and adjustable robust optimization (ARO) method, distributionally robust optimization (DRO) method describes the uncertain wind power output by all possible probability distribution functions (PDFs) with the same mean and variance recovered from the forecast data, and optimizes the expected operation cost in the worst distribution. Traditional DRO optimized the random parameter in entire space, which is sometimes contradict to the actual situation. In this paper, we restrict the wind power uncertainty in a bounded set, and derive an equivalent semi-definite programming (SDP) for the DR-HTW-ED using S-lemma. A delayed constraint generation algorithm is suggested to solve it in a tractable manner. The proposed DR-HTW-ED is compared with the existing ARO based hydro-thermal-wind economic dispatch (AR-HTW-ED). Their respective features are shown from the perspective of computational efficiency and conservativeness of dispatch strategies.

    Ontario Hydro operates 20 CANDU reactors on three different sites. Since 1984, a review of security arrangements on all the sites has taken place on a five-yearly basis. The review process for 1995 is outlined. The three objectives were as follows: to assess current security threats and risks to the stations; to assess the adequacy of the existing programme to protect against current threats; by comparing the security programme against those of comparable entities to establish benchmarks for good practice as a basis for improvements at Ontario Hydro. Valuable insights gained through the review are listed. These could be useful to other utilities. (UK)

    Mineral and thermal waters can contain radioactivity of natural origin which, in some cases, can lead to radiation-protection problems for both workers and consumers. In Italy, as in many other countries, the consumption of bottled mineral water is rather high and the practice of spending short stays in spas is also popular. Consumer protection against natural radioactivity in mineral water is not regulated at all and exposure from thermal waters is not treated in detail, in either the European Union or Italy. For this reason, the Italian Ministry of Health - which has the duty to authorize spa activities and the sale of mineral water on the basis of water characteristics - asked the Istituto Superiore di Sanita (the Italian National Institute of Health) to provide ad-hoc reports containing both dosimetric calculations and analysis of the radiation-protection regulations to be applied in these situations. On the basis of these reports, the Ministry of Health decided, in two statements for spa and mineral waters respectively, to indicate upper levels for natural radioactivity content. Since 2002, spa water parameters have been in force for authorization of their use and sale, and are to be promulgated by specific and more comprehensive regulations. For mineral waters used for infant feeding and drinking, levels lower than those for general public uses have been proposed, in order to take into account the higher ingestion dose coefficients for infants. At the moment, mineral water levels are not enforced as law. This paper presents the dosimetric calculation results and the Ministry of Health statements. (Author) 17 refs

    2010-01-01

    Full Text Available The sum product algorithm on factor graphs (FG/SPA is a widely used tool to solve various problems in a wide area of fields. A representation of generally-shaped continuously valued messages in the FG/SPA is commonly solved by a proper parameterization of the messages. Obtaining such a proper parameterization is, however, a crucial problem in general. The paper introduces a systematic procedure for obtaining a scalar message representation with well-defined fidelity criterion in a general FG/SPA. The procedure utilizes a stochastic nature of the messages as they evolve during the FG/SPA processing. A Karhunen-Loève Transform (KLT is used to find a generic canonical message representation which exploits the message stochastic behavior with mean square error (MSE fidelity criterion. We demonstrate the procedure on a range of scenarios including mixture-messages (a digital modulation in phase parametric channel. The proposed systematic procedure achieves equal results as the Fourier parameterization developed especially for this particular class of scenarios.

    Hydro energy represents a priority in the energy policy of Portugal, with the aim of decreasing the dependence on fossil fuels. In this context, optimal hydro scheduling acquires added significance in moving towards a sustainable environment. A mixed-integer nonlinear programming approach is considered to enable optimal hydro scheduling for the short-term time horizon, including the effect of head on power production, start-up costs related to the units, multiple regions of operation, and constraints on discharge variation. As new contributions to the field, market uncertainty is introduced in the model via price scenarios and risk management is included using Conditional Value-at-Risk to limit profit volatility. Moreover, plant scheduling and pool offering by the hydro power producer are simultaneously considered to solve a realistic cascaded hydro system. -- Highlights: ► A mixed-integer nonlinear programming approach is considered for optimal hydro scheduling. ► Market uncertainty is introduced in the model via price scenarios. ► Risk management is included using conditional value-at-risk. ► Plant scheduling and pool offering by the hydro power producer are simultaneously considered. ► A realistic cascaded hydro system is solved.

Results: We have found that radon levels in SPAs are from a few to several times higher than those in confined spaces, where geothermal waters are not used (e.g., residential buildings. In 82% of the analyzed SPAs, workers may receive doses above 1 mSv/year.

Doses received by SPA visitors are much lower because the time of their exposure to radon released from geothermal water is rather short. Conclusions: The analysis of radon concentration in SPA facilities shows that the radiological protection of people working with geothermal waters plays an important role. It seems reasonable to include SPA workers staying close to geotermal waters into a dosimetric monitoring program. Med Pr 2013;64(2:193–198

    2004-01-01

    This final report for the Swiss Federal Office of Energy looks at the possibilities for improved waste water utilization in the Lavey-les-Bains thermal spa, Switzerland. According to the regulations in force, the temperature of the waste water rejected into the Rhone river shall not exceed 30 o C, what is currently not the case. Also the operational cost shall be reduced and the waste water quality improved. The installations are presented. From the two geothermal wells, mineral water comes out at an average flow rate of 940 l/min and a temperature of 63 o C. Actual waste water data are reported. The measured thermal water consumption data, including seasonal variations, are analysed by computerized simulation and measures to reduce the consumed volume by the optimization of internal procedures are evaluated. Measures to reduce the quantity of the rejected free chlorine are discussed. Several possible adaptations of the existing space heating, domestic water heating and pools' heating are evaluated, including cost. In addition, extensions of the thermal spa center to recreational activities are discussed, as the construction of a tropical greenhouse is

  2. Deconstructing hydro: the BC electricity sector in this decade

    Jaccard, M.

    2001-01-01

    This paper provided speculation regarding the world-wide trend to deregulate electric utilities with particular focus on power deregulation in British Columbia. The four main issues facing electricity reform in British Columbia are to determine if publicly-owned assets should be privatised, how to achieve competitive electricity commodity prices in a de-regulated generation market, to determine the extent to which customers will be allowed direct access to sellers of electricity, and to determine which changes in industry structure are needed to ensure that control over the common carrier does not hinder fair competition. BC Hydro recently issued a plan for the next decade entitled the Integrated Electricity Plan which suggests that almost all growth in supply on the Hydro system will be limited to a few large projects totalling 900 megawatts, to be owned and operated by either BC Hydro or by the Columbia Power Corporation, another Crown entity. This plan is in complete contrast to the evolution of the electricity industry nearly everywhere else in the world where demand growth is being met almost entirely by small- and medium-scale non-utility resources issuing from competitive markets with minimal public funding. This article looks at why BC Hydro will probably be transformed significantly, even dismantled, in the coming decade. The article begins with a section explaining the cause and effects of major changes in the world-wide electricity industry. This is followed by a section reviewing what BC Hydro did in the 1990s while reform was taking place. The article also describes what BC Hydro intends to do in the next decade and explores reasons why this outcome is unlikely. The final section of the article provides an alternative vision of BC Hydro's future over the next decade. 1 tab., 3 figs

    No controlled studies have investigated whether balneotherapy is effective in atopic dermatitis (AD). To investigate the efficacy and safety of balneotherapy performed at Comano spa (Trentino, Italy) compared to topical corticosteroids (TCS) in the treatment of AD. This was an open, randomized, clinical trial including 104 children (aged 1-14 years) with mild to moderate AD who were assigned either to balneotherapy (n = 54) or TCS (n = 50) once daily for 2 weeks. AD severity and quality of life were measured using the SCORAD, investigator global assessment (IGA), patients' self global assessment (PSGA), children's dermatology life quality index (CDLQI) and family dermatitis impact questionnaire (FDIQ). Subjective measures were re-evaluated 4 months after the end of therapy. Balneotherapy and TCS resulted in a significant reduction of all parameters at week 2. TCS were more effective than balneotherapy regarding SCORAD (46% ± 7.71 vs 26% ± 9.4, mean ± SD; p balneotherapy compared to those treated with TCS (p Balneotherapy at Comano spa appears to be beneficial in children with mild to moderate AD.

    Nowadays, some spa centers are suitable for providing rehabilitative and preventive treatment in association with traditional spa therapy. This study aims to evaluate the feasibility and the effectiveness of an intensive rehabilitation program after hip arthroplasty in an Italian spa center. Early after total hip arthroplasty for severe osteoarthritis (≤ 10 days after the intervention), 12 consecutive patients (5 males and 7 females) aged between 50 and 85 years were enrolled for this study. All the patients performed a 2-week thermal multimodal rehabilitation program, which consisted of education and physical rehabilitative measures. Patients had 2-h and half/day session of land-based and hydrokinesitherapy (aquatic therapy) consisted in active and passive joint mobilization, respiratory and functional re-education exercises, gait and balance training, resistance exercise, and power training mainly for the upper limb associated to physical therapy modalities (electrotherapy and low-level laser therapy). An educational program was performed to both patients and families. Both before and after the rehabilitation treatment, patients underwent clinical evaluation, hip flexion/abduction range of motion, and Numeric Pain Rating Scale. Harris Hip Score (HHS) and SF-12 questionnaires (physical—PCS-12—and mental health component—MCS-12) were also administered. After the 2-week thermal spa treatment, hip flexion/abduction improved significantly (p < 0.05), but there was no statistically significant reduction in pain (p = 0.350). The HHS score improved significantly from 62.6 ± 12.8 to 82.15 ± 12.7 (p < 0.05), and the PCS-12 score from 36.37 ± 8.4 to 43.61 ± 8.95 (p < 0.05). There was no adverse event during spa treatment. After total hip arthroplasty, patients who underwent an intensive post-acute multimodal rehabilitation program showed an improvement in motor and functional recovery and a positive impact on quality of life. Therefore, we believe that the

    Full Text Available The famous tradition of spa places like cultural centers and health resorts with unique potential in natural curing springs could be a solid, but not an adequate, ground for their development according to the challenges of contemporary society. The renewed interest in the territorial aspects of tourism as a response to globalization enhanced the influence of spatial factor (tourismscape on current on tourism demand. The network of flows, relationships and interactions, as the core of the territoriality concept, is not something new and unknown in regional planning but requires a new analytical tool for researching the global network connectivity. This paper analyzes the concept of territorial networking in the system of physical, functional and organizational networks as one of the crucial aspects in the development of well balanced tourism region. The consideration aim is to examine and define the relevant indicators that may specify the level of competitiveness of spa region in the global tourism market.

    2001-01-01

    A corporate profile of Hydro-Quebec was presented and the strategy that the utility will adopt for the 2002-2006 period was summarized. The utility plans to maintain its service quality and sustain environmental quality while developing a world class enterprise. Quebec has adopted a heritage pool giving Quebec consumers access to a maximum of 165 TWh of electricity per year at an average commodity rate of 2.79 cents per kilowatt-hour, the lowest rate for such a large amount of energy in North America. Above that volume, supply for the Quebec market will be ensured through competitive bidding, leading to the signing of supply contracts based on market price. Hydro-Quebec's strategy reflects the business opportunities open to Hydro-Quebec given its traditional activities in the province, the restructuring of North American energy markets, and the emergence of Quebec as a major energy hub. The business opportunities come from the fact that demand for electricity in Quebec is growing and from the opening of markets close to Quebec. Investment outlook in hydroelectric generation and transmission also appears to be profitable. It is likely that investment will be needed to build infrastructure. Hydro-Quebec is also working with its qualified workforce to develop a world-class international activity base. tabs., figs

    HydroViz is a web-based, student-centered, highly visual educational tool designed to support active learning in the field of Engineering Hydrology. The development of HydroViz is informed by recent advances in hydrologic data, numerical simulations, visualization and web-based technologies. An evaluation study was conducted to determine the effectiveness of HydroViz, to examine the buy-in of the program, and to identify project components that need to be improved. A total of 182 students from seven freshmen and junior-/senior-level undergraduate classes in three universities participated in the study over the course of two semesters (spring 2010 and fall 2010). Data sources included homework assignments, online surveys, and informal interviews with students. Descriptive statistics were calculated for homework and the survey. Qualitative analysis of students' comments and informal interview notes were also conducted to identify ideas and patterns. HydroViz was effective in facilitating students' learning and understanding of hydrologic concepts and increasing related skills. Students had positive perceptions of various features of HydroViz and they believe that HydroViz fits well in the curriculum. The experience with HydroViz was somewhat effective in raising freshmen civil engineering students' interest in hydrology. In general, HydroViz tend to be more effective with students in junior- or senior-level classes than students in freshmen classes. There does not seem to be obvious differences between different universities. Students identified some issues that can be addressed to improve HydroViz. Future adaptation and expansion studies are under planning to scale-up the application and utility of HydroViz into various hydrology and water-resource engineering curriculum settings.

    International Nuclear Information System (INIS)

    2000-01-01

    A consolidated review of the operations of Newfoundland and Labrador Hydro (Hydro) was presented with particular focus on energy production, energy sales, the Avalon Transmission upgrade, development of the Granite Canal and Hydro's dam safety program. Hydro reported a 4.5 per cent increase in gross energy production at their generating plants throughout the system. Production from hydro sources also increased by 4.5 per cent to a total of 5,032 GWh. Thermal production from the Holyrood generating facility also increased slightly to 1,040 GWh. Production for peaking and emergency requirements from gas turbines and diesel plants dropped to 0.6 GWh. In 2000, about 83 per cent of all the energy supplied to their customers came from hydro sources. Total energy sales were up 4.6 per cent during 2000. This annual report presented the company's financial performance, executive changes, rural rate inquiry, and reorganization. Financial statements included a thorough review and analysis of financial transactions, the auditor's report, and the customary notes to the consolidated financial statement including balance sheets, assets, liabilities and capital. tabs., figs

    2018-06-01

    Full Text Available We present the synthesis and solution properties of dual stimuli-responsive poly(N-isopropylacrylamide-co-spiropyran acrylate (P(NIPAAm-co-SPA copolymers of varying composition prepared via nitroxide-mediated copolymerization. The resulting copolymers feature molar masses from 40,000 to 100,000 g/mol according to static light scattering and an SPA content of up to 5.3%. The latter was determined by 1H NMR spectroscopy and UV–Vis spectroscopy. These materials exhibit reversible response upon irradiation in polymeric films for a minimum of three cycles; their response in solution to both light and temperature was also investigated in an aqueous TRIS buffer (pH 8. Irradiation was carried out using LED setups with wavelengths of 365 and 590 nm. In aqueous solution, a custom-made setup using a fiber-coupled 200 W Hg(Xe lamp with 340 and 540 nm filters was used and additional heating of the copolymer solutions during irradiation allowed to study influence of the presence of either the spiropyran or merocyanine form on the cloud point temperature. Hereby, it was found that increasing the SPA content leads to a more pronounced difference between both states and decreasing cloud points in general.

    Full Text Available Mineral waters from Bardejovske Kupele spa are natural, strongly mineralized, with healing effects. They are classified as hydrocarbonic - containing chloride and sodium - carbonic, cold, hypotonic, with a relatively high boric acid content. Potential anti-oxidative effects of curative waters from Bardejovske Kupele were investigated against the hyaluronan (HA degradation. High-molar-mass HA was exposed to the action of ascorbate and cupric ions, which initiate free-radical chain degradation. Time-dependent changes of dynamic viscosity (h of the HA solutions were monitored by rotational viscometry. The radical scavenging capacity of curative waters was determined by the ABTS assay. Despite a significantly high content of transition metal ions, especially iron, remarkable protective effects of the two curative spa waters were found, namely Alzbeta and Klara. Even though “Alzbeta´s“ iron content was 3.5-fold higher than “Klara´s“, “Alzbeta“ was shown to have better protective properties against the HA degradation compared to “Klara“. Bolus addition of ferric ions to the reaction system instead of the natural iron-containing curative water caused a significant HA degradation. The ABTS decolorization assay revealed that the curative spa waters were proven as poorly effective scavengers of the ABTS·+ cation radical.

  16. Analysis of the Hydro-Quebec development plan 1992-2010

    International Nuclear Information System (INIS)

    Bernard, J.-T.; Genest-Laplante, E.

    1994-01-01

    In November 1992, the Quebec provincial utility Hydro-Quebec presented its development plan for the 1992-2010 period and shortly thereafter introduced its 1993-1995 energy efficiency commitments. The plan is analyzed using a model that incorporates the main institutional features of electricity price setting. Two scenarios are constructed. The first incorporates Hydro-Quebec's electricity demand forecast and the second allows electricity demand to respond to its price. A comparative analysis shows that electricity demand in the province should increase faster than forecast by Hydro-Quebec until 2010. In fact, demand could exceed the predicted level by ca 16 TWh, or 8.6%. This larger increase is due to a fall in the real price of electricity, itself caused by a government imposed fall in the real unit cost of the utility's operation. This last constraint is the real challenge faced by Hydro-Quebec. 12 refs., 7 tabs

  17. Full cost accounting for decision making at Ontario Hydro

    International Nuclear Information System (INIS)

    Plagiannakos, T.

    1996-01-01

    Ontario Hydro's approach to full cost accounting (FCA) was outlined in response to questions raised earlier, in another forum, regarding Ontario Hydro's views on FCA. FCA was defined as an evaluation framework (as opposed to an accounting system) which tries to account for the internal (private) as well as the external (environment and human health) costs and benefits and integrate them into business decisions. When the external impacts cannot be monetized, qualitative evaluations are used based on the damage costing approach, which Ontario Hydro prefers to the cost of control method recommended by its critics. In general, however, Ontario Hydro is not opposed to FCA in so far as it puts the Utility in a better position to make more informed decisions, improve environmental cost management, avoid future costs, enhance revenue, improve environmental quality, contribute to environmental policy, and contribute to sustainable development. 1 fig

    Catalao, J.P.S.; Pousinho, H.M.I.; Mendes, V.M.F.

    2010-01-01

    This paper is on the problem of short-term hydro scheduling, particularly concerning head-dependent cascaded hydro systems. We propose a novel mixed-integer quadratic programming approach, considering not only head-dependency, but also discontinuous operating regions and discharge ramping constraints. Thus, an enhanced short-term hydro scheduling is provided due to the more realistic modeling presented in this paper. Numerical results from two case studies, based on Portuguese cascaded hydro systems, illustrate the proficiency of the proposed approach.

  20. The 12th 735-kV transmission line project: Hydro-Quebec network

    International Nuclear Information System (INIS)

    1992-01-01

    Hydro-Quebec is proposing to construct a 735-kV transmission line from the Chissibi station near the LG3 hydroelectric power plant to the Jacques-Cartier station near Quebec City. The width of the right-of-way will generally be 90 m and it is intended to install the line in two stages. The Chissibi-Chibougamau section should enter service in 1993 and the Chibougamau-Cartier section in 1994. The cost of the line is estimated at $1.21 billion, of which $900 million is for line construction and $310 million for station equipment. Prospective corridors for the line route have been selected, portions of which enable twinning with Hydro-Quebec's existing 9th 735-kV line. A series of hearings on the environmental and other impacts of the power line project was held by the Bureau d'audiences publiques sur l'environnement and results are summarized along with the views of the Bureau. The summary describes the justification for the project, the choice of the transmission line route, the evaluation of the impacts of the project on the natural and human environments, health effects due to magnetic fields, and effects on the economic development of northern Quebec. Recommendations are given for mitigating the impacts of the project. 13 refs., 8 figs., 2 tabs

    HydroShare is an online, collaboration system for sharing of hydrologic data, analytical tools, and models. It supports the sharing of and collaboration around "resources" which are defined by standardized content types for data formats and models commonly used in hydrology. With HydroShare you can: Share your data and models with colleagues; Manage who has access to the content that you share; Share, access, visualize and manipulate a broad set of hydrologic data types and models; Use the web services application programming interface (API) to program automated and client access; Publish data and models and obtain a citable digital object identifier (DOI); Aggregate your resources into collections; Discover and access data and models published by others; Use web apps to visualize, analyze and run models on data in HydroShare. This presentation will describe the functionality and architecture of HydroShare highlighting its use as a virtual environment supporting education and research. HydroShare has components that support: (1) resource storage, (2) resource exploration, and (3) web apps for actions on resources. The HydroShare data discovery, sharing and publishing functions as well as HydroShare web apps provide the capability to analyze data and execute models completely in the cloud (servers remote from the user) overcoming desktop platform limitations. The HydroShare GIS app provides a basic capability to visualize spatial data. The HydroShare JupyterHub Notebook app provides flexible and documentable execution of Python code snippets for analysis and modeling in a way that results can be shared among HydroShare users and groups to support research collaboration and education. We will discuss how these developments can be used to support different types of educational efforts in Hydrology where being completely web based is of value in an educational setting as students can all have access to the same functionality regardless of their computer.

  2. Hydro Tasmania - renewable energy drivers, action and plans

    International Nuclear Information System (INIS)

    Gill, R.; Andrews, H.

    2005-01-01

    In Tasmania, the island state of Australia, the generator, Hydro Tasmania, is pushing technical, environmental and business boundaries in its plans to integrate a relatively high proportion (up to 20 percent) of large wind generators into its current complex mix of large and small hydropower plants. Its plans include projects to increase the efficiency of its older hydropower equipment as it prepares to supply much needed peaking capacity to the market in southern Australia via the groundbreaking Basslink undersea cable, which is due for completion in November 2005. Taken as a package these developments are creating a globally significant reference site for renewable energy systems. The paper will describe what is happening, and more importantly what is underpinning the developments, including: the harnessing of Tasmania's world-class wind resource, where recently constructed 1.75 MW wind turbines are achieving capacity factors of over 45 percent - some of the best productivity in the world today; the application of leading environmental science measures to ensure the sustainability of both the new wind farm developments and the transformation of the hydropower system to meet peak capacity demands; the relevance of the existing large hydropower storages that can operate in synergy with the wind resource; the contribution of Australia's renewable energy certificate scheme, which is effectively doubling the value of new renewable energy developments compared with existing generation sources; the application of the latest technology in hydropower turbines, combined with power system expertise from the world's leading manufacturers, to increase the efficiency of older hydropower generators, thereby more effectively harnessing the existing environmental footprint; and the transformation of Hydro Tasmania's business into a significant supplier and trader of premium value peak energy into the sophisticated Australian National Electricity Market.

  4. Smooth pursuit adaptation (SPA exhibits features useful to compensate changes in the properties of the smooth pursuit eye movement system due to usage.

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Smooth-pursuit adaptation (SPA refers to the fact that pursuit gain in the early, still open-loop response phase of the pursuit eye movement can be adjusted based on experience. For instance, if the target moves initially at a constant velocity for approximately 100-200ms and then steps to a higher velocity, subjects learn to up-regulate the pursuit gain associated with the initial target velocity (gain-increase SPA in order to reduce the retinal error resulting from the velocity step. Correspondingly, a step to a lower target velocity leads to a decrease in gain (gain-decrease SPA. In this study we demonstrate that the increase in peak eye velocity during gain-increase SPA is a consequence of expanding the duration of the eye acceleration profile while the decrease in peak velocity during gain-decrease SPA results from reduced peak eye acceleration but unaltered duration. Furthermore, we show that carrying out stereotypical smooth pursuit eye movements elicited by constant velocity target ramps for several hundred trials (= test of pursuit resilience leads to a clear drop in initial peak acceleration, a reflection of oculomotor and/ or cognitive fatigue. However, this drop in acceleration gets compensated by an increase in the duration of the acceleration profile, thereby keeping initial pursuit gain constant. The compensatory expansion of the acceleration profile in the pursuit resilience experiment is reminiscent of the one leading to gain-increase SPA, suggesting that both processes tap one and the same neuronal mechanism warranting a precise acceleration/ duration trade-off. Finally, we show that the ability to adjust acceleration duration during pursuit resilience depends on the integrity of the oculomotor vermis (OMV as indicated by the complete loss of the duration adjustment following a surgical lesion of the OMV in one rhesus monkey we could study.

  7. More than energy: Ontario Hydro final annual report, January 1998 - March 1999

    International Nuclear Information System (INIS)

    1999-01-01

    Ontario Hydro ceased operations on March 31, 1999 and its assets and functions were transferred by provincial statute to two successor corporations: Ontario Power Generation Corp. (OPG) and Ontario Hydro Services Inc. Its functions were also transferred to the Independent Electricity Market Operator and the Electrical Safety Authority, two not-for-profit agencies. The original act defining Ontario Hydro was replaced by the Energy Competition Act, 1998. Until the demerger of the company on April 1, 1999, Ontario Hydro served 108 direct industrial clients, almost one million retail clients and 255 municipal utilities. Ontario Power Generation inherited Ontario Hydro's generating portfolio, making it one of the largest power producers in North America in terms of installed capacity. The OPG system includes 69 hydroelectric stations, three nuclear sites, and six operating fossil fueled stations. Total installed system capacity is approximately 31,000 megawatts, and Ontario Hydro's total sales in 1998 were almost 139 terawatt hours. Ontario Hydro Services Company is an energy services-based transmission and distribution company. It owns and maintains 29,000 km of transmission lines, 114,700 km of distribution lines, 245 km of high-voltage underground cable, 256 transformer stations, 928 distribution and regulation stations, and 250 microwave stations. It also retains the retail business held by Ontario Hydro, which serves over 950,000 clients, and the transmission and generating business for 23 remote communities in Northern Ontario

    The aim of this study was to examine the effect of age and spa treatment (i.e. combined sauna, cold water immersion, and jacuzzi) on match running performance over two consecutive matches in highly trained young soccer players. Fifteen pre- (age 12.8 ± 0.6 years) and 13 post- (15.9 ± 1 y) peak height velocity (PHV) players played two matches (Matches 1 and 2) within 48 h against the same opposition, with no specific between-match recovery intervention (control). Five post-PHV players also completed another set of two consecutive matches, with spa treatment implemented after the first match. Match running performance was assessed using a global positioning system with very-high-intensity running (> 16.1-19.0 km · h(-1)), sprinting distance (>19 km · h(-1)), and peak match speed determined. Match 2 very-high-intensity running was "possibly" impaired in post-PHV players (-9 ± 33%; ± 90% confidence limits), whereas it was "very likely" improved for the pre-PHV players (+27 ± 22%). The spa treatment had a beneficial impact on Match 2 running performance, with a "likely" rating for sprinting distance (+30 ± 67%) and "almost certain" for peak match speed (+6.4 ± 3%). The results suggest that spa treatment is an effective recovery intervention for post-PHV players, while its value in pre-PHV players is questionable.

    1985-01-01

    Ontario Hydro is a large Canadian utility producing 84% (7394 MWe) of the Nuclear Electricity generated in Canada. The low- and intermediate-level radioactive wastes generated by the Ontario Hydro program are currently being managed at the Bruce Nuclear Power Development with various volume reduction, packaging and interim storage systems. Ontario Hydro also owns and operates a radioactive waste transportation system. Studies are in progress for final disposal of these wastes in a suitable geology in Ontario. Since its inception in 1971, Ontario Hydro's radioactive waste management program has evolved into providing a full fledged radioactive waste management capability to the utility's two nuclear generation centres at Pickering and Bruce, and later in the decade, to Darlington. This paper summarizes the various developments in this program; highlights the major facilities both in-service and planned to be built; reviews the experiences gained over fifteen years of in-house waste management; and discusses the proposed reorientation towards ultimate disposal of these wastes. 2 refs., 8 figs., 1 tab

    The 'Elguea' spa, located in the north coast of the county of Villa Clara, Cuba, is considered one of those more important spas of Latin America. The waters of this spa are rich in salts of chlorine, sodium, bromine, sulfides and its contain radon. As a result of measurements of environmental gamma dose rates carried out in the area of the spa, its were considered levels of dose between 0.13 and 2.3 mSv. The obtained results motivated that it was carried out a characterization, from the radiological point of view, of the spa. This characterization is of supreme importance to be able to evaluate the impact that it has and the discharges of its waters on the environment, as well as, those dose that the population potentially affected can receive by these discharges. With this end its were carried out quantitative determinations of those existent natural more significant radionuclides in different environmental objects coming from the area of the spa and its surroundings, as well as one characterization gamma 'in situ' of the same one. The obtained results are present in this work. (Author)

    2005-01-01

    One of the major tasks in the field of hydraulic power engineering refers to machines and equipment modernization in the hydropower plants and pumped storage power plants commissioned more than 20 years ago. The increase of hydraulic units operation efficiency will allow in a number of cases to substantially reduce the specific water consumption and to drive the output of electric energy up. In these cases it is crucial to find out the operational efficiency of individual system elements and to precisely focus the modernization endeavours on such elements where the energy losses go beyond all admissible limits. Besides, the determination of the energy losses in the hydro energy turbo system will allow valid defining of hydraulic units operational scope. This work treats the methods of balance study of a hydraulic unit with Peiton water turbine. The experimental results of the balance study of Belmeken pumped storage power plant hydraulic unit No 5 under turbine operational mode are presented

    The environmental impact of energy production and use with the associated emissions of greenhouse gases, particularly CO 2 , has created much attention and growing concern at both national and international levels. In Egypt, efforts have been directed to incorporate the environment-protection issues within the overall planning of the energy sector, as appropriate to its national commitment and its techno-economic considerations. Over the past decade, 1985-1995, hydro-power had contributed between 28 and 22% of the total energy produced by Egyptian power-plants, while the contribution of the hydro capacity was between 32.4 and 21.5%. Many studies have been carried out on the impacts of the Aswan High Dam on various aspects of the environment. An objective evaluation of the Dam, based on 25 years of operational data, indicated that it has overall been positive even though it has contributed to some environmental problems. These problems, however, are significantly less than most people originally expected. This paper deals with the review and analysis of the detrimental effects of hydro-power in Egypt. An evaluation will be given of the emissions of greenhouse gases from the whole hydro-chain. (Author)

    The history of the electric utility Hydro-Quebec is reviewed from its creation in 1944 as the Hydroelectric Commission of Quebec. The utility inherited an installed capacity of 696 MW and it first went about standardizing electricity supply conditions and establishing equal rates in the Montreal area. It began major construction projects in the mid-1950s with the Bersimis and Carillon hydroelectric plants. By 1962, installed capacity reached 3,657 MW. In 1963, Hydro-Quebec bought 10 private electricity distribution companies, 45 cooperatives, and a series of private or municipal systems. In 1965, the utility commissioned the world's first 735-kV transmission line. In 1967, Hydro-Quebec opened its research institute, and another laboratory specializing in electrotechnologies was opened in 1987. The 1970s were noted for the James Bay hydroelectric projects, the development of which was eventually governed by the landmark James Bay and Northern Quebec Agreement of 1975. Electricity exports greatly expanded in the 1970s and early 1980s as larger hydroelectric projects came on stream. Challenges of the 1990s include service quality, environmental issues, energy efficiency, and conservation. Hydro-Quebec's Energy Efficiency Project has a target of annual savings of 9.3 TWh by the year 2000. Energy efficiency and power system upgrading are priorities for serving future customer needs. Hydro-Quebec continues to promote hydroelectric power as the cheapest, most environmentally benign form of energy and future generating stations in progress include phase II of the LaGrande complex (to be completed 1996). 2 figs

  19. Marginal-cost pricing for Hydro-Quebec residential customers

    An option available to governments and to utilities such as Hydro-Quebec for responding to objectives of energy efficiency is the adoption of marginal cost pricing. Compared to currently used price structures, marginal cost pricing will allow improvement of price signals and assure an optimal utilization of the resource. That type of pricing could be economically beneficial but may not be desirable from the point of view of revenue distribution. Taking account of Hydro-Quebec's cost structure, pure marginal cost pricing would generate an income that would be strongly contested on equity grounds. For example, it would raise prices 60% for residential customers. Faced with this possibility, an analysis is presented of the impact of a peak-offpeak pricing (or pure marginal cost pricing) on Hydro-Quebec's residential customer energy bills. The marginal costs of Hydro-Quebec are calculated by the method of Bernard and Chatel (1985) and analysis of the results is based on Friedman and Weare (1993). A sample of 28,417 residential customers from a 1989 Hydro-Quebec survey is used in the study. Two scenarios are analyzed; the first allowing comparison of the energy bill only on the basis of marginal costs and of average costs, and the second allowing comparison of the impact of marginal cost pricing on the total bill. In the first scenario, the impact translates into a 31% increase in energy bills for the entire customer class considered; in addition, this impact is inversely proportional to the revenue class. In the second scenario, the increase is 24%. 33 refs., 10 figs., 53 tabs

  20. The Present and Future of Szigetvár Spa – An Economic Analysis of Geothermal Energy Investment

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available In Hungary, geothermal energy has proved to be an economical source of energy for direct use. It highlights the pros and cons of including renewable energy in the power generation mix of Hungary, and the pros and cons of local application. This paper looks at the operation of Szigetvár Spa from both economic and social aspects. In this study, qualitative analysis is used for the basic economic and social introduction of the Spa, and then real options, based on quantitative methods, are described to identify the long-term financial consequences of the project. In 1966, thermal water was found in Szigetvár. In 1997, this thermal water was certified as medicinal water. The wellhead temperature of Szigetvár thermal water is 62°C in the 790 metres deep thermal well. It is used as so-called domestic hot water in the Szent István housing estate and in Szigetvár Spa. One of the problems with the project is that it is based on single stage thermal water utilization, another problem is that the waste water is too hot. This can be solved by exploiting the heat energy of thermal water more intensively. This way, maximum benefits can be gained from geothermal energy with minimum use of energy. Static and dynamic investment analyses were carried out to examine the spa from a financial aspect. The methods used include static payback period, average rate of return, levelized cost of electricity, net present value, profitability index, dynamic payback period, internal rate of return and real options. By pricing geothermal technology, it is possible to identify the strategic value of flexibility, to quantify what was previously left unquantified, and thus to show that geothermal investments are profitable not only from a social but also from a financial aspect as well.

  1. Power Management Based Current Control Technique for Photovoltaic-Battery Assisted Wind-Hydro Hybrid System

    Science.gov (United States)

    Ram Prabhakar, J.; Ragavan, K.

    2013-07-01

    This article proposes new power management based current control strategy for integrated wind-solar-hydro system equipped with battery storage mechanism. In this control technique, an indirect estimation of load current is done, through energy balance model, DC-link voltage control and droop control. This system features simpler energy management strategy and necessitates few power electronic converters, thereby minimizing the cost of the system. The generation-demand (G-D) management diagram is formulated based on the stochastic weather conditions and demand, which would likely moderate the gap between both. The features of management strategy deploying energy balance model include (1) regulating DC-link voltage within specified tolerances, (2) isolated operation without relying on external electric power transmission network, (3) indirect current control of hydro turbine driven induction generator and (4) seamless transition between grid-connected and off-grid operation modes. Furthermore, structuring of the hybrid system with appropriate selection of control variables enables power sharing among each energy conversion systems and battery storage mechanism. By addressing these intricacies, it is viable to regulate the frequency and voltage of the remote network at load end. The performance of the proposed composite scheme is demonstrated through time-domain simulation in MATLAB/Simulink environment.

    1996-01-01

    Manitoba Hydro was the first Canadian utility to initiate a program to decontaminate insulating oil contaminated with polychlorinated biphenyls (PCBs). This paper describes Manitoba Hydro's recovery, reuse and recycling program, operated out of the utility's Waverley Service Centre (WSC). The WSC is a central facility serving to phase out and and destroy PCBs which remain in Manitoba Hydro's electrical system. Several hundred thousand litres of PCB-contaminated insulating oil are decontaminated annually at the WSC. The decontaminated oil is then reconditioned for reuse within the system operations. A PCBX unit was purchased from Sun Ohio for the decontamination of insulating oils containing PCBs. PCB decontamination is achieved through a chemical dechlorination treatment process. The PCBX treatment unit and the PCB storage building were described. 18 refs., 8 figs

  3. Higher profits, lower bills : a new electricity strategy for Hydro-Quebec

    International Nuclear Information System (INIS)

    2010-01-01

    Quebec is the fourth largest producer of hydro-electricity in the world, and has among the lowest electricity rates in North America. In 2008, 89 percent of the electricity produced by Hydro-Quebec was sold in the province, and the remainder was exported. In 2009, the electric utility released its strategic plan for 2009 to 2013. Hydro-Quebec's net profits are forecast to decline by 24 percent by 2013 and electricity rates are forecast to rise by 8.5 percent. Since Hydro-Quebec has already developed all of the province's low-cost hydroelectric resources, it can no longer increase profits and lower rates by building new hydropower production stations. In order to continue to prosper, the utility will invest in energy efficiency and better coordination of its power system with Ontario's. Increased electricity exports from Hydro-Quebec will help both Ontario and the United States reduce their greenhouse gas emissions by displacing fossil power generation. 25 refs., 2 tabs., 3 figs.

    2001-07-01

    Development of a power system data communication architecture (PSDCA) at British Columbia Hydro that enables authorized corporate users to access station-intelligent electronic devices (IEDs) for power system data in non real-time, without compromising the reliability and availability of the real-time SCADA systems, is described. Also discussed is the development of major upgrade initiatives for expanding the use of intelligent electronic devices and remote terminal units (RTUs) which report to the main System Control Centre at Burnaby, BC, and to the four Area Control Centres located throughout the province. The network architecture that incorporates industry standards for PSDCA also provides an opportunity to existing network security systems against electronic threats such as hackers and saboteurs, beyond the simple methods of single or two-level passwords of existing protection control and monitoring equipment systems. The virtual private network (VPN) technology built into the PSDCA will allow secure access to station IED data by corporate users to access their own power data in a secure and reliable fashion. 4 figs.

  6. How would the privatization of Hydro-Quebec make Quebecers richer?

    Garcia, C.

    2009-02-01

    In 1962, a total of 46 companies shared Quebec's electricity production, involving no less than 9,710 megawatts of power. The 4 companies that controlled 85 per cent of this power were Hydro-Quebec, Aluminum Company of Canada (Alcan), Shawinigan Water and Power Company and the Gatineau Power Company. At the time, electricity rates also varied considerably throughout Quebec, being extremely high in regions far from Montreal, which hindered potential industrial development in those areas. This report discussed the privatization of Hydro-Quebec and how it could make Quebecers richer. The report discussed the early days of electricity in Quebec and outlined the reasons that led Quebec to nationalize the production and distribution of electricity and to entrust its management to Hydro-Quebec. A summary of the developments undertaken to enable Hydro-Quebec to substantially boost its exports to the United States following liberalization of the American market toward the end of the twentieth century was also provided. A comparison group of companies in the United States involved in the production, transmission and distribution of electricity was also presented in order to analyze Hydro-Quebec's performance from various standpoints. Other topics that were addressed in the report included operational efficiency; use of capital; the experience of the United Kingdom; the rise in electricity rates; a strategy for privatization; the public offering; and protecting Quebec electricity consumers. The role of the Quebec government and of Hydro-Quebec were also examined. Electricity exports and electricity and aluminum smelters were also assessed. The report noted that Hydro-Quebec's annual profit would shrink from $2,882 million to $709 million if it had to pay the market price for the electricity it obtains from Churchill Falls. 23 tabs., 1 fig., 2 appendices

  7. Production method of hydrogen jet plasma process in hydro machinery

    Amini, F.

    2007-01-01

    The purpose of present paper is to the process of plasma formation in hydro machinery when a hydro turbine operates at various conditions and load rejection. By investigation the power, shock pressure , and impact effects of hydro machinery, it is revealed that energy and hydrogen are generated by the plasma process. The investigation on several turbines of various hydro power plants reveals that cold fusion process in hydro machinery generates hydrogen. The hypothesis concerning the participation of alkaline metals in river water and the atomic nuclei of the runner blade material in the formation of hydrogen are considered. It is possible to assume hydrogen, deuterium, helium, and tritium atoms (based on Dr. Mizuno and Dr. Kanarev theories) that are formed, diffuse into cavitation bubbles. The plasma is generated during the collapse of the bubble; thus, the quantity of burnt hydrogen determine the volume of generating hydrogen and the impact force caused by hydrogen explosion (noise).There are five main notions, which can determine hydrogen and plasma process: (1) turbine power effect, (2) high shock pressure, (3) crack on turbine parts, (4) impacts effects and (4) the lift of rotating parts. The frequency of the excitation lies in a range from 0.786 to 1.095 Hz.In future, it may be possible to design hydro turbines based on the plasma process that generates hydrogen; or there may exist turbines that rotate with a mixture of hydrogen explosion and water energies

    The governments of most Latin American countries have yet to establish clear policies about the future ownership of existing generation assets, but they do expect future capacity to be largely developed by the private sector. There were at one time plans for many government-financed hydro projects in the area, but these projects produced much paper and little electricity. Present trends will take the area toward independent power projects, both hydro projects and thermal power projects. This article is a review of those present trends

    Ankylosing spondylitis (AS) can cause severe functional disorders that lead to loss of balance. The aim of this study was to investigate the effects of balance and postural stability exercises on spa based rehabilitation programme in AS subjects. Twenty-one participants were randomized to the study (n= 11) and control groups (n= 10). Patients balance and stability were assessed with the Berg Balance Scale (BBS), Timed Up and Go (TUG) Test, Single Leg Stance Test (SLST) and Functional Reach Test (FRT). AS spesicied measures were used for assessing to other parameters. The treatment plan for both groups consisted of conventional transcutaneous electrical nerve stimulation (TENS), spa and land-based exercises 5 days per week for 3 weeks. The study group performed exercises based on postural stability and balance with routine physiotherapy practice in thermal water and in exercise room. The TUG, SLST and FUT scores were significantly increased in the study group. In both groups, the BASMI, BASFI, BASDAI and ASQoL scores decreased significantly by the end of the treatment period (pbalance and stability exercises in addition to spa based routine approaches can increase the duration of maintaining balance and can improve the benefits of physiotherapy.

    Full Text Available Staphylococcus aureus is a leading cause of bacteremia in hospitalized patients. Whether or not S. aureus bacteremia (SAB is associated with clonality, implicating potential nosocomial transmission, has not, however, been investigated. Herein, we examined the epidemiology of SAB using whole genome sequencing (WGS. 152 SAB isolates collected over the course of 2015 at a single large Minnesota medical center were studied. Staphylococcus protein A (spa typing was performed by PCR/Sanger sequencing; multilocus sequence typing (MLST and core genome MLST (cgMLST were determined by WGS. Forty-eight isolates (32% were methicillin-resistant S. aureus (MRSA. The isolates encompassed 66 spa types, clustered into 11 spa clonal complexes (CCs and 10 singleton types. 88% of 48 MRSA isolates belonged to spa CC-002 or -008. Methicillin-susceptible S. aureus (MSSA isolates were more genotypically diverse, with 61% distributed across four spa CCs (CC-002, CC-012, CC-008 and CC-084. By MLST, there was 31 sequence types (STs, including 18 divided into 6 CCs and 13 singleton STs. Amongst MSSA isolates, the common MLST clones were CC5 (23%, CC30 (19%, CC8 (15% and CC15 (11%. Common MRSA clones were CC5 (67% and CC8 (25%; there were no MRSA isolates in CC45 or CC30. By cgMLST analysis, there were 9 allelic differences between two isolates, with the remaining 150 isolates differing from each other by over 40 alleles. The two isolates were retroactively epidemiologically linked by medical record review. Overall, cgMLST analysis resulted in higher resolution epidemiological typing than did multilocus sequence or spa typing.

    1998-01-01

    Progress made by BC Hydro to facilitate the use of the transmission system for wholesale electricity transactions, including the separation of the system operation function from generation and merchant functions, was discussed. BC Hydro, Canada's third largest electric utility, was the first Canadian utility to offer open access to its transmission system for wholesale transactions. The utility has an installed generating capacity of about 10.8 gigawatts, 90 per cent of which is hydroelectric. The remainder is thermal, gas turbine and stationary and mobile diesel generation. The key element in establishing wholesale transmission transactions was the FERC-mandated open access same-time information system (OASIS) on which BC Hydro posts available transmission capacity, planned outages and pricing. The system operates on BC Hydro's internet node and interfaces to a Transmission Scheduling System (TSS). The TSS was developed in-house to handle the increased complexity of scheduling multiple energy and capacity transactions for users of the transmission system. Operation of the system and the challenge to constantly improve it were discussed

    2014-10-01

    Full Text Available The hydro unit economic load dispatch (ELD is of great importance in energy conservation and emission reduction. Dynamic programming (DP and genetic algorithm (GA are two representative algorithms for solving ELD problems. The goal of this study was to examine the performance of DP and GA while they were applied to ELD. We established numerical experiments to conduct performance comparisons between DP and GA with two given schemes. The schemes included comparing the CPU time of the algorithms when they had the same solution quality, and comparing the solution quality when they had the same CPU time. The numerical experiments were applied to the Three Gorges Reservoir in China, which is equipped with 26 hydro generation units. We found the relation between the performance of algorithms and the number of units through experiments. Results show that GA is adept at searching for optimal solutions in low-dimensional cases. In some cases, such as with a number of units of less than 10, GA's performance is superior to that of a coarse-grid DP. However, GA loses its superiority in high-dimensional cases. DP is powerful in obtaining stable and high-quality solutions. Its performance can be maintained even while searching over a large solution space. Nevertheless, due to its exhaustive enumerating nature, it costs excess time in low-dimensional cases.

  18. Development of a Scintillation Proximity Assay (SPA) Based, High Throughput Screening Feasible Method for the Identification of PDE12 Activity Modulators.

    2016-01-01

    The scintillation proximity assay (SPA) technology has been widely used to establish high throughput screens (HTS) for a range of targets in the pharmaceutical industry. PDE12 (aka. 2'- phosphodiesterase) has been published to participate in the degradation of oligoadenylates that are involved in the establishment of an antiviral state via the activation of ribonuclease L (RNAse-L). Degradation of oligoadenylates by PDE12 terminates these antiviral activities, leading to decreased resistance of cells for a variety of viral pathogens. Therefore inhibitors of PDE12 are discussed as antiviral therapy. Here we describe the use of the yttrium silicate SPA bead technology to assess inhibitory activity of compounds against PDE12 in a homogeneous, robust HTS feasible assay using tritiated adenosine-P-adenylate ([3H]ApA) as substrate. We found that the used [3H]ApA educt, was not able to bind to SPA beads, whereas the product [3H]AMP, as known before, was able to bind to SPA beads. This enables the measurement of PDE12 activity on [3H]ApA as a substrate using a wallac microbeta counter. This method describes a robust and high throughput capable format in terms of specificity, commonly used compound solvents, ease of detection and assay matrices. The method could facilitate the search for PDE12 inhibitors as antiviral compounds.

    Scintillation proximity assay is a one of radioimmunoassay and can be assayed without the washing or filtration procedures normally used to separate bound from free fractions. Due to its simplicity and high-throughput protocol, it is broadly applicable to immunology, receptor binding, monitoring receptor-ligand interactions and enzyme reactions. Briefly, an antibody or receptor is coated on SPA beads. When a radiolabeled antigen or ligand binds to the beads, the SPA beads stimulate to emit short range electrons. The 3 H and 125 I are commonly used for radiolabeling and the produced photons are detectable with a liquid scintillation counter (LSC). A binding affinity of unlabeled ligands can be determined by competitive reaction of the radiolabeled ligands. Bevacizumab is a recombinant humanized monoclonal antibody, and can stop or delay growth of tumors by inhibiting vascular endothelial growth factor (VEGF). Bevacizumab was approved by FDA for metastatic cancer such as colorectal cancers, ovarian cancers, breast cancers and glioblastoma multiform of the brain. Recently, Dan G. duda et al. was reported that the concentration of vascular endothelial growth factor receptor-1 (VEGFR-1) in plasma may potentially be used as a negative selection biomarker. In this study, we describe a method using scintillation proximity assay to detect the amounts of VEGFR-1 protein. This method is successfully used to measure the concentration of VEGFR-1 protein in human cell extracts. In summary, a simple and sensitive assay is developed for measuring the amount of VEGFR 1 protein in cancer cell lysate using SPA beads. The antibody coating on the beads and antigen binding are achieved in one mixing step

    Although it is believed that the information economy is replacing the mass economy, many companies continue to grow on economies based on natural resources. Recent aggressive growth by Hydro-Quebec in the highly competitive market for energy products was singled out as one of the success stories. Among other things, Hydro-Quebec was reported to focus attention on the globalization of electricity products, particularly in Asia, Europe and Africa. The corporation was said to cooperate with other utilities companies such as Ontario Hydro and Power Asia Assets Corporation to diversify its markets abroad. Hydro-Quebec is also marketing new products, developed in its laboratories and by subsidiaries, such as power system simulators and power system planning and management systems, on a global scale

  9. The hydro-mechanical modeling of the fractured media

    2002-10-01

    The hydro-mechanical modeling of the fractured media is quite complex. Simplifications are necessary for the modeling of such media, but, not always justified, Only permeable fractures are often considered. The rest of the network is approximated by an equivalent continuous medium. Even if we suppose that this approach is validated, the hydraulic and mechanical properties of the fractures and of the continuous medium are seldom known. Calibrations are necessary for the determination of these properties. Until now, one does not know very well the nature of measurements which must be carried out in order to carry on a modeling in discontinuous medium, nor elements of enough robust validation for this kind of modeling. For a better understanding of the hydro-mechanical phenomena in fractured media, two different sites have been selected for the work. The first is the site of Grimsel in Switzerland in which an underground laboratory is located at approximately 400 m of depth. The FEBEX experiment aims at the in-situ study of the consecutive phenomena due to the installation of a heat source representative of radioactive waste in the last 17 meters of the FEBEX tunnel in the laboratory of Grimsel. Only, the modeling of the hydro-mechanical of the excavation was model. The modeling of the Febex enabled us to establish a methodology of calibration of the hydraulic properties in the discontinuous media. However, this kind of study on such complex sites does not make possible to answer all the questions which arise on the hydro-mechanical behavior of the fractured media. We thus carried out modeling on an other site, smaller than the fist one and more accessible. The experimental site of Coaraze, in the Maritime Alps, is mainly constituted of limestone and fractures. Then the variation of water pressure along fractures is governed by the opening/closure sequence of a water gate. Normal displacement as well as the pore pressure along these fractures are recorded, and then

    Hydro-abrasive erosion of hydraulic turbines is an economically important issue due to maintenance costs and production losses, in particular at high- and medium-head run-of- river hydropower plants (HPPs) on sediment laden rivers. In this paper, research and development in this field over the last century are reviewed. Facilities for sediment exclusion, typically sand traps, as well as turbine design and materials have been improved considerably. Since the 1980s, hard-coatings have been applied on Francis and Pelton turbine parts of erosion-prone HPPs and became state-of-the-art. These measures have led to increased times between overhauls and smaller efficiency reductions. Analytical, laboratory and field investigations have contributed to a better processes understanding and quantification of sediment-related effects on turbines. More recently, progress has been made in numerical modelling of turbine erosion. To calibrate, validate and further develop prediction models, more measurements from both physical model tests in laboratories and real-scale data from HPPs are required. Significant improvements to mitigate hydro-abrasive erosion have been achieved so far and development is ongoing. A good collaboration between turbine manufacturers, HPP operators, measuring equipment suppliers, engineering consultants, and research institutes is required. This contributes to the energy- and cost-efficient use of the worldwide hydropower potential.

    This article recounted the experience of a 14-member Hydro-Quebec line crew and support group that travelled to Haiti in November 2004 to help re-establish essential electricity services. The work was conducted together with Electricite d'Haiti (EDH). The team installed 400 poles, 10 km of conductors and 85 transformers, restoring service to water pumps; La Providence and Raboteau hospitals; a centre housing Doctors without borders; a CARE distribution centre; and several convents and schools. The installation of street lights at strategic points allowed lighting to be restored in several districts of Gonaives. Hydro-Quebec was able to extend their mission to Haiti and purchase more poles and transformers with the help of a $500,000 contribution from the Canadian International Development Agency. Hydro-Quebec was the only company who came to the aid of EDH. The total budget for the project was $4 million. 2 figs.

    The Crimea has the enormous potential for the health promotion activities. However, neither the profile of these activities nor the demand for the socio-medical services is clearly defined for the majority of the local spa and health resort facilities. The possibilities of modern information technology are not used in the full measure either. The objective of the present work was to elaborate the new medical information system and demonstrate its effectiveness. In addition, the article describes the main advantages of the system for the optimization of healthcare in the Crimean spa and health resort facilities. We reviewed and analyzed various literature publications, legal framework, standards, regulations, guidelines, and questionnaire survey data obtain at 50 spa and health resort facilities of the Crimea. The results of the assessment indicate the necessity of the systematic approach to the analysis of the quality of medical care and the process of its further development. Statistical and mathematical methods were used to elaborate the medical information system for the optimization of the activities of the Crimean spa and health resorts. The distinctive features of the proposed information system are modularity and the possibility of flexible adjustment to the conditions of individual settings, one-step data loading with the subsequent multiple application for the formulation of documents, automated filling of records in compliance with the medical standards, and taking into consideration the possible changes in or amendments to the form of the documents. The data obtained in the course of project implementation were used for the first time in the Republic of Crimea to design, substantiate, and recommend for the practical application the algorithm for the comprehensive estimation of the results of treatment of the patients based at the spa and health resort facilities with due regard for the specific regional conditions.

    This study aimed to investigate the correlation of the image associated by the design Co-Brand (Jimmy S.P.A. and STRAUSS) and the impression perceived by subject of viewers. Visual images were used to examine the merit of the evaluation. The best result is provided using an object as an appropriate evaluation method. There are a lot of factors which influence to evaluation of a design. This study is limited to distinguish the appearance from Jimmy's picture books transform furniture and so on. Co-Brand of Jimmy S.P.A. and STRAUSS is not easy because there are not from the same cultural, and industry background and applying different marketing strategy, it is a way to combine the two brands by designing, used questionnaire of SD (Semantic differential evaluation) evaluation method to test out the perception of viewers, the objective of this study is to investigate and appraised the Co-Brands use by of the image in furniture from patrons. SD evaluation result showed, if design cannot understand the perception image of Jimmy S.P.A and STRAUSS with viewers mind, furniture design also can't transmit feeling with design.

    With the ever increasing demand for electricity, it is estimated that the world`s electrical generating capacity will grow by about 1,000,000 MW over the next eight years. This represents a 40 per cent increase over today`s capacity. Hydro-Quebec is determined to stake its place in international markets and to maximize the profits from the strong expertise gained during the construction of Quebec`s major electric facilities. The venture into international markets is primarily a commercial strategy. To that effect, Hydro-Quebec plans to invest up to $300 million in international projects around the world so that after five years it can have major interests and assets totaling $12 billion or more. China, North Africa and the Middle East are some of the market that Hydro-Quebec wishes to enter in the years ahead. The Eastern European and Southeast Asian markets are also worthy of interest. It was pointed out that Hydro-Quebec is not the only large electric utility turning to world market to pursue its growth. French, Spanish and American companies are also presently investing billions of dollars in the world market.

    The HydroCoil is an expansile hydrogel coil designed to produce a greater degree of volumetric packing within cerebral aneurysms when compared with bare platinum coils. This increased packing is, in turn, believed to decrease the risk of recurrence within aneurysms and hence the risk of their rupture in the long term. The aim of this work was to assess whether the use of HydroCoils and the proportion of HydroCoil used have any influence on the subsequent occlusion and recurrence rates of treated aneurysms.

    The purpose of this study was to establish a rat model of a brain injury with tracheotomy and compared the wetting effects of different airway humidification liquids, afterward, the best airway humidification liquid was selected for the clinical trial, thus providing a theoretical basis for selecting a proper airway humidification liquid in a clinical setting. Rats were divided into a sham group, group A (0.9% NaCl), group B (0.45% NaCl), group C (0.9% NaCl+ambroxol) and group D (0.9% NaCl+Pulmicort). An established rat model of traumatic brain injury with tracheotomy was used. Brain tissue samples were taken to determine water content, while lung tissue samples were taken to determine wet/dry weight ratio (W/D), histological changes and expression levels of SP-A mRNA and SP-A protein. 30 patients with brain injury and tracheotomy were selected and divided into two groups based on the airway humidification liquid instilled in the trachea tube, 0.45% NaCl and 0.9% NaCl+ambroxol. Blood was then extracted from the patients to measure the levels of SP-A, interleukin-6 (IL-6), interleukin-8 (IL-8) and tumour necrosis factor-α (TNF-α). The difference between group C and other groups in lung W/D and expression levels of SP-A mRNA and SP-A protein was significant (Phumidification liquid. Copyright © 2015 Elsevier B.V.

    2017-01-01

    Abstract Background and objective: Idiopathic pulmonary fibrosis (IPF) has a poor prognosis in general; however, it is heterogeneous to detect relative biomarkers for predicting the disease progression. Serum biomarkers can be conveniently collected to detect and help to differentially diagnose IPF and predict IPF prognosis. This meta-analysis aimed to evaluate the use of serum surfactant proteins A and D (SP-A and SP-D) for differential diagnosis and prognosis of IPF. Methods: Relevant articles were searched in PubMed, Embase, and Chinese National Knowledge Infrastructure databases and reviewed by 2 independent readers. Standard mean difference (SMD) and 95% confidence interval (CI) were calculated to assess the difference in serum levels of SP-A/D among patients with IPF, when compared to patients with non-IPF interstitial lung disease (ILD), pulmonary infection, and healthy control. Hazard ratio (HR) and 95% CI were used to compare the relative risk of mortality. Results: Twenty-one articles (totalling 1289 IPF patients) were included in final meta-analysis. Serum SP-A levels were significantly higher in patients with IPF than in patients with non-IPF ILD (SMD: 1.108 [0.584, 1.632], P infection (SMD: 1.320 [0.999, 1.640], P SMD: 2.802 [1.901, 3.702], P SMD: 0.459 [−0.000, 0.919], P = .050). Serum SP-D levels were significantly higher in patients with IPF than in patients with pulmonary infection (SMD: 1.308 [0.813, 1.803], P SMD: 2.235 [1.739, 2.731], P < .001). Risk of death in patients with IPF and elevated serum SP-A was increased 39% compared to patients with low SP-A groups. Elevated SP-D increased risk by 111% when compared to low SP-D. In acute exacerbation of IPF, serum SP-A/D were higher than those in stable stage. The comparisons and prognosis might be different in Asian and Caucasian patients. Conclusions: Serum SP-A/D detection might be useful for differential diagnosis and prediction of survival in patients with IPF. PMID:28591049

  7. Impact on the aquatic environment of hydro-peaking in hydroelectric plants

    International Nuclear Information System (INIS)

    Sabaton, C.; Lauters, F.; Valentin, S.

    1996-01-01

    There are a number of types of hydroelectric installations on French rivers. Some of these intermittently turbine water stored in dammed reservoirs, in order to use available reserves at the most opportune moment for power generation. These plants, run under 'hydro-peaking' management procedures, cause variations in discharge in river sections downstream of the restitution, on a daily or weekly scale. To answer questions concerning the impact of such variations in discharge on the aquatic environment, EDF launched a research program aimed at describing and better understanding the physical and biological phenomena related to hydro-peaking and assessing the possible impact of this type of plant management on French streams. Seven sites subjects to hydro-peaking were studied on rivers with mean flow rates lower than 20 m 3 /s (which corresponds to over 65 % of EDF hydro-peaking sites). Four themes in particular were examined: hydraulic characterization of hydro-peaking, modifications in thermal regime and water quality, response of benthic invertebrates and response of fish populations to hydro-peaking. For fish as well as for invertebrates, the role of the base discharge - in the absence of peaking flow - and that of the morphology of the river bed (and, in particular, the presence of shelter for fish) during periods of strong discharge were clearly highlighted. Impact assessment requires a precise diagnosis of the state of biocenoses. To carry out such a diagnosis, one must reason in terms of species, life phase (particularly the most sensitive phases) and population structure as well as the type of stream and the faunizone involved. A risk assessment is possible by means of simultaneous study of the morphology of the river bed and the response of the signal generated by hydro-peaking in terms of hydrology and physical characteristics downstream of the restitution.

    1999-10-01

    A special prosecutor has been appointed by the British Columbia Government to assist the Royal Canadian Mounted Police (RCMP) in its investigation, and to render appropriate charging decisions in the matter of the circumstances surrounding the creation of IPC International Power Corporation (IPC) owned by a Mr. John N. Laxton, former Chairman of BC Hydro and his two children, and its joint venture with BC Hydro for the development of an international power project in Pakistan known as the Raiwind project. Of particular concerns were the conflict of interest breached by Mr. Laxton in loaning a substantial sum of money to a principal member of the Pakistani side of the joint venture, and by the former President and CEO of BC Hydro, Mr. John Sheehan, by his purchase of shares of IPC by a company owned by members of his family. In 1996 Mr. Sheehan's employment as President and CEO was terminated by BC Hydro for breaching internal conflict of interest guidelines and for failing to get approval from BC Hydro for the acquisition of IPC shares. Subsequently, Mr. Sheehan commenced an action against BC Hydro for wrongful dismissal, a claim which was upheld by the Supreme Court of British Columbia. The focus of the special prosecutor's criminal investigation ultimately became the conduct of Mr. Laxton and whether a charge could or should be laid under Section 122 of the Criminal Code. The outcome of his investigation, which is discussed in this report, was that there was no substantial likelihood of conviction under the breach or trust provisions of Section 122 with respect to the indirect purchases by Mr. Laxton of shares in IPC. Nor was there any reason to believe that a personal loan made in high-risk circumstances could be a benefit or advantage to the lender. Furthermore, the loan cannot be causally related to any loss or financial harm to BC Hydro. In fact, it could be argued that Mr. Laxton's private decision to make the loan was of real assistance in ensuring that the

    A cost-benefit analysis is presented of the energy conservation programs of Hydro-Quebec for 1991 to 2010. Three possible scenarios are simulated. In the first scenario, Hydro-Quebec data are used without modification. In the second, the simulation is carried out in the absence of the Hydro-Quebec programs, and in the third, it is assumed that any economies achieved are only for the short term. A comparison between these simulations allows determination of results concerning the advantages and the costs which the programs introduce for the three groups comprising society: the consumer, the producer, and the government. The results of these comparisons show that the consumer, the producer, and the whole society gain benefits from the energy conservation programs, while the government loses. 13 refs., 13 figs., 14 tabs

    2006-01-01

    The Energy Drill Program is a demand response tool and economic instrument based on a fire drill protocol. The aim of the program is to reduce peak demand and emissions and improve system reliability and price volatility. This presentation provided details of an Energy Drill pilot program, conducted in Milton, Ontario. Customized approaches were used in the buildings partaking in the drill, which included the Milton Hydro Headquarters, the Robert Baldwin Public School, and a leisure centre. Building assessments inventoried building systems and equipment usage patterns. Pilot monitoring and evaluation was conducted through the use of checklists completed by marshals and building coordinators. Energy use data was tracked by Milton Hydro, and report cards were sent after each drill. A short-term drop in demand was observed in all the buildings, as well as overall reductions in peak period demand. Energy consumption data for all the buildings were provided. Results of the pilot program suggested that rotating the drills among participating buildings may prove to be a more effective strategy for the program to adopt in future. A greater emphasis on energy efficiency was also recommended. It was concluded that the eventual roll-out strategy should carefully consider the number and types of buildings involved in the program; internal commitment to the program; available resources; and timing for implementation. refs., tabs., figs

    This thesis studied the thermo-hydro-mechanical properties of Boom clay, which was chosen to be the host material for the radioactive waste disposal in Mol, Belgium. Firstly, the research was concentrated on the soil water retention properties and the hydro-mechanical coupling by carrying out axial compression tests with suction monitoring. The results obtained permitted elaborating a rational experimental procedure for triaxial tests. Secondly, the systems for high pressure triaxial test at controlled temperature were developed to carry out compression, heating, and shearing tests at different temperatures. The obtained results showed clear visco-elasto-plastic behaviour of the soil. This behaviour was modelled by extending the thermo-elasto-plastic model of Cui et al. (2000) to creep effect. (author)

    1992-01-01

    The Quebec government now requires Hydro-Quebec to submit a development plan every three years instead of annually, in order to permit more in-depth studies and a broader consultation with interested parties. In the first of such three-year plans, a series of plan proposals is presented which was developed after a year of consultation with various groups on four fundamental matters: energy efficiency, means of generation, electro-intensive industries, and electricity exports. Options for meeting future demand at Hydro-Quebec are assessed, including the construction of new generation and transmission facilities, rehabilitation of existing facilities, improving electrical energy efficiency, and conservation strategies. These options are considered while applying the principle of sustainable development that respects the environment. Hydroelectricity will continue to be emphasized as the main source of generation since hydroelectric facilities offer distinct advantages in terms of costs, environmental impacts, and economic spinoffs. The proposed plan also presents objectives and strategies for improving the quality of service and internal operations. Financial forecasts for Hydro-Quebec are proposed which take into account the forecast changes in the utility's cost and revenue factors and its self-financing requirements. 5 figs., 15 tabs

  4. Economically viable and environment-friendly hydro energy in Estonia

    2001-01-01

    Hydro energy has been in oblivion in Estonia for about 30 years now. During the 1960s, most of Estonia's small hydropower plants were closed down, just as it was done in the whole Soviet Union. As the only larger hydro plant, the 125 MW plant in Narva, was situated on the Russian side of the Narva River, there were only two or three small hydro plants left. Even those were exploited at low capacity and mainly for heating the buildings. It was not until the 1990s that a number of enthusiasts started to re-establish the hydro plants by reconstructing old installations. The pre-feasibility study 'Hydropower in Estonia' proposed by Estonian and Swedish experts, showed that the restoration of the hydropower plants and watermills is economically feasible and technically possible if advanced technology is used. Hydropower as an alternative ('green') energy source should be used in the best technical-economical way. The first pilot plant in Estonia, the 200 kW Kamari plant was constructed in 1998 with compact-propeller units, in co-operation with Waterpumps WP Oy and ABB. Today, ten new plants have been constructed or are under construction. Hydropower plants/watermills should be reconstructed in accordance with the legislative acts on environment protection

    The present hydro energy system in Bulgaria has been constructed mainly in the period 1950-1965. The currently utilized hydro-power potential, only 33% of the estimated technical potential, includes 87 HPP operating in 1991. A complex assessment of the environmental impact of the hydro energy objects as well as a comparative analysis of all energy sources in Bulgaria is made in the framework of Bulgarian Case Study of the DECADES Inter-Agency Project. The main types of environmental impact related to HPP operation are presented in 7 specific categories: land requirements, changes in the landscape, hydrological changes, micro-climatic changes, geodynamic changes, risk from man-made activities; generation of new ecosystems. A technique of expertise in ball is proposed as a suitable quantitative approach for more precise assessment of impact on climate factors from different energy sources. 2 tabs., 5 refs

    The most common form of utility- sized energy storage system is the pumped storage hydro system. Originally, these types of storage systems were economically viable simply because they displace more expensive generating units. However, over time, as those expensive units became more efficient and costs declined, pumped hydro storage units no longer have the operational edge. As a result, in the current electricity market environment, pumped storage hydro plants are struggling. To offset this phenomenon, certain market modifications should be addressed. This paper will introduce some of the challenges faced by pumped storage hydro plants in today's markets and purpose some solutions to those problems.

  12. Cost-effectiveness and efficacy of spa, SCCmec, and PVL genotyping of methicillin-resistant Staphylococcus aureus as compared to pulsed-field gel Electrophoresis.

    Directory of Open Access Journals (Sweden)

    Vincent Li

    Full Text Available Pulsed-field gel electrophoresis (PFGE is a valuable molecular typing assay used for methicillin-resistant Staphylococcus aureus (MRSA surveillance and genotyping. However, there are several limitations associated with PFGE. In Alberta, Canada, the significant increase in the number of MRSA isolates submitted to the Provincial Laboratory for Public Health (ProvLab for PFGE typing led to the need for an alternative genotyping method. In this study, we describe the transition from PFGE to Staphylococcus protein A (spa, Staphylococcal cassette chromosome (SCCmec, and Panton-Valentine leukocidin (PVL typing. A total of 1915 clinical MRSA isolates collected from 2005 to 2009 were used to develop and validate an algorithm for assigning PFGE epidemic types using spa, SCCmec, and PVL typing and the resulting data was used to populate a new Alberta MRSA typing database. An additional 12620 clinical MRSA isolates collected from 2010 to 2012 as part of ongoing routine molecular testing at ProvLab were characterized using the new typing algorithm and the Alberta MRSA typing database. Switching to spa, SCCmec, and PVL from PFGE typing substantially reduced hands-on and turn-around times while maintaining historical PFGE epidemic type designations. This led to an approximate $77,000 reduction in costs from 2010 to 2012. PFGE typing is still required for a small subset of MRSA isolates that have spa types that are rare, novel, or associated with more than one PFGE epidemic type.

    In this study, we report the electrodeposition of a chitosan/layered double hydroxides (LDHs) hydro-membrane for protein release triggered by an electrical signal. The electrodeposition was performed in a chitosan and insulin loaded LDHs suspension in the absence of salt. A free-standing chitosan/LDHs hydro-membrane was generated on the electrode with improved mechanical properties, which is dramatically different from the weak hydrogel deposited in the presence of salt. The amount of LDHs in the hydro-membrane affects the optical transmittance and multilayered structure of the hybrid membrane. Compared to the weak chitosan/LDHs hydrogel, the hydro-membrane has a higher insulin loading capacity and the release of insulin is relatively slow. By biasing electrical potentials to the hydro-membrane, the release behavior of insulin can be adjusted accordingly. In addition, the chitosan/LDHs hydro-membrane showed no toxicity to cells. Our results provide a facile method to construct a chitosan/LDHs hybrid multilayered hydro-membrane and suggest the great potential of the hydro-membrane in controlled protein release.

    Hydro-conversion of coal hydro liquefaction residue obtained from a 6 t/day pilot plant of Shenhua Group in Shanghai was carried out under the hydrotreating condition. The coal hydro liquefaction residue and its product were extracted in sequence with n-hexane, toluene and tetrahydrofuran in a Soxhlet apparatus. The n-hexane soluble fractions increased with the increase of reaction temperature and time. Its amount increased from 14.14% to a maximum of 40.86% under the conditions of 470 {sup o}C and 30 min, which meant that moderate extension of coal residence time in the coal hydro liquefaction reactor is beneficial to the increase of oil yield. A 4-lumped kinetic model of coal hydro liquefaction residue hydro-conversion was performed using solubility-based lumped fractions. In the model, the tetrahydrofuran insoluble fractions were classified into two parts: easily reactive part and unreactive part. The kinetic parameters were estimated by a fourth-order Runge-Kutta method and a nonlinear least squares method, and the apparent activation energies were calculated according to the Arrhenius Equation. A large quantity of total catalyst consisting of remained liquefaction catalyst, part of the mineral from raw coal and additive Fe-based catalyst could considerably reduce the apparent activation energy of hydro-conversion for the toluene insoluble/tetrahydrofuran insoluble fractions to 36.79 kJ-mol{sup -1}. The calculated values of the model coincided well with the experimental values. (authors)

    BC Hydro's installed generation capacity as of March 31, 2003 was 11,103 MW, of which 90 per cent was hydro power, 9 per cent was gas-fired and 1 per cent was non-integrated. The hydroelectric plants belong to one of three groups, the Peace River, Columbia River or small hydro which includes small to moderate sized-plants. Small hydro is controlled by hydrologic regime and storage limitations rather than by system requirements. The installed capacity for the 4 plants on the Columbia River totals 4,722 MW. The installed capacity at the 2 plants on the Peace River totals 3,424 MW. Both watersheds are subject to interior climate conditions with significant inflows from snowmelt and rainfall runoff. This presentation addressed the issue of mid-term hydro scheduling and its impact on markets. For the past 15 years, BC Hydro has used the marginal cost model for electricity trade and for operations planning. The model considers system loads and resources, and maximizes the expected net revenue over a planning horizon of 6 years. A marginal value of water stored in the Williston Reservoir has been established using the marginal cost model. The affect of weather, natural gas prices and water supply on hydro generation was also discussed. It was noted that information on spot market electricity prices has significantly improved since the electric power industry was deregulated in 1996. tabs., figs

    Small hydro system is one of the important sources of renewable energy and it has been recognized worldwide as clean energy sources. Small hydropower generation system uses the potential energy in flowing water to produce electricity is often questionable due to inconsistent and intermittent of power generated. Potential analysis of small hydro system which is mainly dependent on the availability of water requires the knowledge of water flow or stream flow distribution. This paper presented the possibility of applying Pearson system for stream flow availability distribution approximation in the small hydro system. By considering the stochastic nature of stream flow, the Pearson parametric distribution approximation was computed based on the significant characteristic of Pearson system applying direct correlation between the first four statistical moments of the distribution. The advantage of applying various statistical moments in small hydro potential analysis will have the ability to analyze the variation shapes of stream flow distribution.

    A new composite material based on alumina (Al2O3) modified by two surface nanocoatings - titanium dioxide (TiO2) and silver (Ag) - was studied for spa water disinfection. Regarding the most common microorganisms in bathing waters, two non-pathogenic bacteria Escherichia coli (Gram-negative) and Staphylococcus epidermidis (Gram positive) were selected as surrogates for bacterial contamination. The bactericidal properties of the Al2O3-TiO2-Ag material were demonstrated under various operating conditions encountered in spa water (temperature: 22-37 °C, presence of salt: CaCO3 or CaCl2, high oxygen content, etc.). Total removal of 10(8) CFU mL(-1) of bacteria was obtained in less than 10 min with 16 g L(-1) of material. Best results were observed for both conditions: a temperature of 37 °C and under aerobic condition; this latest favouring Reactive Oxygen Species (ROS) generation. The CaCO3 salt had no impact on the bactericidal activity of the composite material and CaCl2 considerably stabilized the silver desorption from the material surface thanks to the formation of AgCl precipitate. Preliminary tests of the Al2O3-TiO2-Ag bactericidal behaviour in a continuous water flow confirmed that 2 g L(-1) of material eliminated more than 90% of a 2.0 × 10(8) CFU mL(-1) bacterial mixture after one water treatment recycle and reached the disinfection standard recommended by EPA (coliform removal = 6 log) within 22 h.

  2. Reversible pumped hydro - benefits and challenges

    Full text: The Norwegian hydro power system is dominated with high head turbines, Pelton and Francis with high capacity in the reservoirs. Originally they were built for secure energy supply. In the system there are also reversible pump turbine (RPT) plants where in times with spare energy, made it possible to pump water from the lower reservoir to the higher. Again the idea was to secure energy supply, which meant pumping in early autumn to fill the reservoirs for winter. In the recent years, a more active use of the RPT plants has been actualized. The free market made price difference between night and day interesting, hence a more frequent pumping was desirable. In the coming years, new-renewable energy sources will utterly enhance a more active use of the RPT plants. More active use of the RPT plants means more frequent starts and stops, both in pumping and in turbine mode. There are a lot of challenges in adopting a new strategy for operating the machinery. More effective start equipment is required. The machinery will be exposed to more frequent dynamic loads; the turbines will be run at part- and full load. The existing RPT plants are connected to huge reservoirs. That means the RPTs are not only for short sighted power regulations, as many RPT-plants in Europe, but are also capable for a substantial energy production. In Norway, the nature is very suitable for RPT plants, both in connection with existing power plants, were reservoirs and conduits are already established, and standing alone with a minimum of energy production. RPTs are, as a design, a compromise between effective generating and stable as well as effective pumping. Stable pumping often results in very steep flow-speed characteristics when operating as a turbine. When dealing with hydraulic transients these characteristics cause a higher change in flow and torque leading to instability during start-up and possible off-design operation point. The instability slows down the synchronization

    The approaches based on different particle swarm optimization (PSO) techniques are applied to solve the short-term hydro-thermal scheduling problem. In the proposed methods, many constraints of the hydro-thermal system, such as power balance, water balance, reservoir volume limits and the operation limits of hydro and thermal plants, are considered. The feasibility of the proposed algorithm is demonstrated through an example system, and the results are compared with the results of a genetic algorithm and evolutionary programming approaches. The experimental results show that all the PSO algorithms have the ability to achieve nearly global solutions, but a local version of PSO with inertia weight appears to be the best amongst all the PSOs in terms of high quality solution

    HydroImage, user friendly software that utilizes high-resolution geophysical data for estimating hydrogeological parameters in subsurface strate, was developed under this grant. HydroImage runs on a personal computer platform to promote broad use by hydrogeologists to further understanding of subsurface processes that govern contaminant fate, transport, and remediation. The unique software provides estimates of hydrogeological properties over continuous volumes of the subsurface, whereas previous approaches only allow estimation of point locations. thus, this unique tool can be used to significantly enhance site conceptual models and improve design and operation of remediation systems. The HydroImage technical approach uses statistical models to integrate geophysical data with borehole geological data and hydrological measurements to produce hydrogeological parameter estimates as 2-D or 3-D images.

    Introduction The overall safety of the HydroCoil, an expansile hybrid hydrogel-platinum coil, is unknown. We report a prospective observational study of our first 100 cerebral aneurysms treated with HydroCoils, focusing on safety and initial efficacy.Methods Indications, procedural complications, clinical and angiographic outcomes were recorded. Packing density, number of coils deployed and angiographic results were compared with those in a matched control group of 100 aneurysms treated solely with bare platinum coils. HydroCoil complication rates were compared to bare platinum coil rates at our institution and in published series. Results Adjuvant HydroCoil treatment led to increased mean percentage aneurysm filling compared to controls (50 ± 21% versus 27 ± 13%, P < 0.001). Immediate posttreatment angiographic results showed significantly (P < 0.001) more complete occlusions and fewer incomplete (<95%) occlusions compared to controls. Intermediate follow-up angiograms (median 7.5 months) in 63 aneurysms showed a trend towards fewer incomplete occlusions with HydroCoil treatment. There were significantly fewer major recurrences with HydroCoil treatment compared to the control treatment (9.5% versus 22.6%, P 0.046). In the adjuvant HydroCoil group, major recurrent aneurysms had significantly less percentage volume packing with HydroCoils than non-recurrent aneurysms (50.3 ± 5.0% versus 65.3 ± 18.0%, P = 0.04). There was a 12% procedural complication rate, 6% procedural morbidity and 1% mortality rate, similar to institutional and reported bare platinum coil complication rates.Conclusion HydroCoils can be safely deployed with a similar complication rate to bare platinum coils. They result in improved aneurysm filling. Intermediate follow-up angiography showed significantly fewer major recurrences. Long-term follow-up is required to confirm initial improved stability.

    Reaction turbines basically Francis turbines and propeller/Kaplan turbines are suitable for medium and low head hydropower sites. The management of the small hydropower plants is an important factor, for achieving higher efficiency of hydro turbines with time. Turbines show declined performance after few years of operation, as they get severely damaged due to various reasons. One of the important reasons is erosive wear of the turbines due to cavitation. Reaction turbines, however are more prone to cavitation especially Francis turbines where a zone in the operating range is seriously affected by cavitation and considered as forbidden zone. Cavitation is a phenomenon which manifests itself in the pitting of the metallic surfaces of turbine parts because of the formation of cavities. In the present paper, studies undertaken in this field by several investigators have been discussed extensively. Based on literature survey various aspects related to cavitation in hydro turbines, different causes for the declined performance and efficiency of the hydro turbines and suitable remedial measures suggested by various investigators have been discussed.

  8. Hydro-Thermal Fatigue Resistance Measurements on Polymer Interfaces

    Science.gov (United States)

    Gurumurthy, Charan K.; Kramer, Edward J.; Hui, Chung-Yuen

    1998-03-01

    We have developed a new technique based on a fiber optic displacement sensor for rapid determination of hydro-thermal fatigue crack growth rate per cycle (da/dN) of an epoxy/polyimide interface used in flip chip attach microelectronic assembly. The sample is prepared as a trilayered cantilever beam by capillary flow of the epoxy underfill over a polyimide coated metallic beam. During hydro-thermal cycling the crack growth along the interface (from the free end) changes the displacement of this end of the beam and we measure the free end displacement at the lowest temperature in each hydro-thermal cycle. The change in beam displacement is then converted into crack growth rate (da/dN). da/dN depends on the maximum change in the strain energy release rate of the crack and the phase angle in each cycle. The relation between da/dN and maximum strain energy release rate characterizes the fatigue crack growth resistance of the interface. We have developed and used a simple model anhydride cured and a commercially available PMDA/ODA passivation for this study.

    1997-01-01

    Hydro-Quebec Energy Services US (HQUS), the marketing arm of Hydro-Quebec, amended its application for a power marketing licence with the Federal Energy Regulatory Commission (FERC), by offering to open up five per cent of the wholesale Quebec electricity market to competition. The Corporation hopes that its revised application will satisfy FERC to grant HQUS a power marketer licence, with the right to sell electricity in the US at market-based rates. Hydro-Quebec insiders believe that in addition to opening up the market to competition, thereby equalizing market conditions on both sides of the border, the Corporation's chances of receiving the licence also have been improved by the creation of the provincial energy board (Regie de l'energie) which in future will regulate electricity and gas transmission through Quebec, and establish transmission tariffs. FERC ruling is expected within 60 days of the March 7, 1997 amended application

    2014-01-01

    Research around micro-hydro power is focused on technical aspects with limited understanding of the social organisation and environmental implications. We examine the ways in which micro-hydro is engaged by people and organisations as a means of contributing to the UK's policy ambition for renewable energy. We bring to the fore the way in which expertise is used and contested. A web based review of micro-hydro schemes in the UK was undertaken and a detailed evaluation of two schemes in the North of England was conducted to determine how expertise and contestation figures in community schemes. Results demonstrate a rapid expansion of micro-hydro in the UK. Ownership/control is highly ‘community based’. Until now research around micro-hydro has been dominated by technical approaches with schemes defined in terms of hardware. We propose a third dimension to Walker and Cass's (2007) classification of renewable energy developments: the environmental dimension. We suggest this dimension of micro-hydro is critical, both in terms of the extent to which resources can be realised but also the ways in which it might attract controversy, in particular around how expertise is used and valued. - Highlights: • Analysis of micro-hydro schemes in the UK demonstrates a recent rapid expansion. • We propose a third dimension to renewable energy developments: the environmental dimension. • The environmental dimension of micro-hydro determines how resources are realised. • Environmental features underpin the controversy which can emerge around schemes. • The ownership of micro-hydro schemes is highly ‘community based’

    2016-01-01

    Eco-hydraulic investigations studying the effects of hydro-peaking on river biota are gaining in importance. Negative effects of rapid flow fluctuations due to hydro power production are well documented by many studies, with the larvae and juvenile fish identified among the mostly affected life stages. Therefore, elaboration of efficient hydro-peaking mitigation strategies is an important issue for energy companies as well as for water body administrations responsible for the fulfilment of WFD requirements. The present case study strives for practical solutions allowing to minimize or compensate the negative effects of hydro-peaking on the fish fauna of the 7 km long river reach on the river Lech (southern Germany). Model based investigations allow to access the impact from currently authorized discharge regime, suggest operational and structural measures within the reach in terms of reducing the risk of stranding for fish larvae and select the measures most easy to implement and with the largest ecological benefit. The paper describes the approach for accessing the effects of hydro-peaking based on 2D hydrodynamic modelling, fuzzy logic based habitat modelling and information on cutting-edge biological investigations on fish larvae from Lunz experimental facility (Austria).

    This paper is on the problem of short-term hydro scheduling (STHS), particularly concerning a head-dependent hydro chain. We use a method based on nonlinear programming (NLP), namely quadratic programming, to consider hydroelectric power generation a function of water discharge and of the head. The method has been applied successfully to solve a test case based on a realistic cascaded hydro system with a negligible computational time requirement and is also applied to show that the role played by reservoirs in the hydro chain do not depend only on their relative position. As a new contribution to earlier studies, which presented reservoir operation rules mainly for medium and long-term planning procedures, we show that the physical data defining hydro chain parameters used in the nonlinear model have an effect on the STHS, implying different optimal storage trajectories for the reservoirs accordingly not only with their position in the hydro chain but also with the new parameterisation defining the data for the hydro system. Moreover, considering head dependency in the hydroelectric power generation, usually neglected for hydro plants with a large storage capacity, provides a better short-term management of the conversion of the potential energy available in the reservoirs into electric energy, which represents a major advantage for the hydroelectric utilities in a competitive electricity market.

    1995-01-01

    Hydro-Quebec's telecommunication system, the largest private telecommunications network in Canada, was discussed. The network was set up to assure safety and efficiency of the power plants and energy transmission and distribution lines. By the year 2000 Hydro-Quebec will need electronic links with all its industrial, commercial and residential customers in order to guarantee competitive service and full customer satisfaction. Investments of about one half billion dollars have been earmarked to boost the capacity of their telecommunications grid and meet steadily growing needs. As a result of the very difficult negotiations to resolve the native land claims issue, Hydro-Quebec was forced to adapt a strict and far-reaching environmental policy, which is now beginning to pay off not only in environmental terms, but also in terms of goodwill among actual and prospective customers. As a result of these huge infrastructure projects Hydro Quebec will be in a position to guarantee people access to energy at a price that is among the lowest in the world. Although demand growth could slow, demand itself will not wane. As part of this overall strategy, Hydro-Quebec plans to defer large-scale projects, instead, for the foreseeable future it will concentrate on smaller power plants, some of which could be built on rivers that have already been tamed

  18. Using ecosystem services to represent the environment in hydro-economic models

    Demand for water is expected to grow in line with global human population growth, but opportunities to augment supply are limited in many places due to resource limits and expected impacts of climate change. Hydro-economic models are often used to evaluate water resources management options, commonly with a goal of understanding how to maximise water use value and reduce conflicts among competing uses. The environment is now an important factor in decision making, which has resulted in its inclusion in hydro-economic models. We reviewed 95 studies applying hydro-economic models, and documented how the environment is represented in them and the methods they use to value environmental costs and benefits. We also sought out key gaps and inconsistencies in the treatment of the environment in hydro-economic models. We found that representation of environmental values of water is patchy in most applications, and there should be systematic consideration of the scope of environmental values to include and how they should be valued. We argue that the ecosystem services framework offers a systematic approach to identify the full range of environmental costs and benefits. The main challenges to more holistic representation of the environment in hydro-economic models are the current limits to understanding of ecological functions which relate physical, ecological and economic values and critical environmental thresholds; and the treatment of uncertainty.

    The present study has attempted to apply the advantage of neuro-genetic algorithms for optimal decision making in maximum utilization of natural resources. Hydro-power is one of the inexpensive, but a reliable source of alternative energy which is foreseen as the possible answer to the present crisis in the energy sector. However, the major problem related to hydro-energy is its dependency on location. An ideal location can produce maximum energy with minimum loss. Besides, such power-plant also requires substantial amount of land which is a precious resource nowadays due to the rapid and unco

    1993-01-01

    Hydro regulation models provide extensive support for analyzing the efficacy of salmon recovery plans in the Northwest. Power planners developed these computer programs to help plan and efficiently operate a large multiple use river system. The models represent physical relationships and operational requirements on the system. They also simulate coordinated system operations for efficient power generation. These models are being pressed into service to provide data for fish recovery plans. They provide important information about hydro system capabilities and responses to recovery programs. However, the models cannot meet all of the analytical needs of fish biologists working toward salmon recovery

    Most utilities that have achieved high performance have introduced a management model to improve performance and operate plants safely. The Nuclear Energy Institute has developed and updated its Standard Nuclear Performance Model (SNPM) in order to provide a summary of nuclear processes, cost definitions, and key business performance measures for business performance comparison and benchmarking. Over the past decade, Korea Hydro and Nuclear Power Co. (KHNP) has introduced and implemented many engineering processes such as Equipment Reliability (ER), Maintenance Rule (MR), Single Point Vulnerability (SPV), Corrective Action Program (CAP), and Self Assessment (SA) to improve plant performance and to sustain high performance. Some processes, however, are not well interfaced with other processes, because they were developed separately and were focused on the process itself. KHNP is developing a Standard Equipment Management Model (SEMM) to integrate these engineering processes and to improve the interrelation among the processes. In this paper, a draft model and attributes of the SEMM are discussed.

  5. Hydro investment analysis under new market conditions

    Energy Technology Data Exchange (ETDEWEB)

    Doorman, Gerard

    2010-07-01

    Full text: A future energy system with stronger coupling to Europe and with an increased share of non-regulated renewables will lead to increasing variability of the demand faced by the hydro system. In a market based system these variations will be reflected by larger daily price variations, both in the Elspot day ahead market, the Elbas intraday market and in the balancing market. With its unique regulation capabilities, hydro power will be very well positioned to handle these variations. However, existing model concepts for long term hydro scheduling were not developed for this framework, and do not take the new market conditions into account to a sufficient degree. Therefore hydro scheduling tools used for upgrading and investment analysis as well as analysing consequences of new environmental demands need adaptation to a finer temporal resolution, and to perform optimisation under varying constraints and uncertain input data for inflow and electricity prices. Focus is on investment analysis for a river system or power producer. Existing models can be grouped in the long-term (scheduling models with a time horizon up to 5 years) EOPS (Vansimtap), EOPS-ST (SimtapEffekt) and ProdRisk, and the shortterm scheduling models with a typical time horizon up to a few weeks, but focus on 1-2 days (SHOP and ID-SIM). A perfect tool in the present context would combine the properties of the long term stochastic optimisation models with the modelling details of SHOP and/or ID-SIM. However, this is probably not possible and simplifications will be necessary. Some important deficiencies in the present long term models are: Insufficiently realistic plant models in the relevant optimization models; Time delays are not handled; Handing of flexible / state dependent constraints; Handling of ramping constraints; Modelling of the cost of frequent regulations (wear and tear); Reserve markets As a result of these deficiencies the investment analysis does not adequately assess the value

    This volume is a collection of 10 papers presented at a conference in which the challenges of restructuring the electric power industry in Ontario were discussed. Legal experts, policy makers, economists and stakeholders in the industry presented their views regarding the future of the industry in Ontario. The implications of privatization were discussed. There was general agreement on the need for some industry de-integration and privatization. However, agreement on the exact nature of the approach to take was more divided. For example, opinion was divided on what the logical endpoint of industry restructuring should be i.e. wholesale or retail competition. Also contentious was the question of what portion of Hydro's generating assets should be sold off to private enterprise if Hydro's generation and transmission assets are unbundled. Opinions were also divided about the environmental consequences of nuclear energy. Significant differences of opinion were evident concerning the privatization of Ontario Hydro's nuclear assets. refs., tabs., figs

    1997-01-01

    The implications of a take-over of Gaz Metropolitain by Hydro-Quebec in early 1997 and the pricing of electricity and natural gas in Quebec were discussed. In January 1997, Hydro-Quebec purchased all the shares in Noverco that were formerly owned by SOQUIP. With this purchase, Hydro-Quebec became the major share holder in Noverco, the company that controls Gaz Metropolitain. This type of take-over, where an electrical utility purchases the interests in a natural gas distributor, has also been observed in the United States and is believed to be a consequence of the recent deregulation of the electricity market. In the near future, it is believed that consumers will probably pay for equivalent energy use (like heating or cooling) rather than separate tariffs for electricity or natural gas consumption. The recent popularity of gas-fueled electrical cogenerating stations is also believed to be an important factor in this take-over. 1 ref., 3 tabs

  16. Gross greenhouse gas fluxes from hydro-power reservoir compared to thermo-power plants

    Santos, Marco Aurelio dos; Pinguelli Rosa, Luiz; Sikar, Bohdan; Sikar, Elizabeth; Santos, Ednaldo Oliveira dos

    2006-01-01

    This paper presents the findings of gross carbon dioxide and methane emissions measurements in several Brazilian hydro-reservoirs, compared to thermo power generation. The term 'gross emissions' means gas flux measurements from the reservoir surface without natural pre-impoundment emissions by natural bodies such as the river channel, seasonal flooding and terrestrial ecosystems. The net emissions result from deducting pre-existing emissions by the reservoir. A power dam emits biogenic gases such as CO 2 and CH 4 . However, studies comparing gas emissions (gross emissions) from the reservoir surface with emissions by thermo-power generation technologies show that the hydro-based option presents better results in most cases analyzed. In this study, measurements were carried in the Miranda, Barra Bonita, Segredo, Tres Marias, Xingo, and Samuel and Tucurui reservoirs, located in two different climatological regimes. Additional data were used here from measurements taken at the Itaipu and Serra da Mesa reservoirs. Comparisons were also made between emissions from hydro-power plants and their thermo-based equivalents. Bearing in mind that the estimated values for hydro-power plants include emissions that are not totally anthropogenic, the hydro-power plants studied generally posted lower emissions than their equivalent thermo-based counterparts. Hydro-power complexes with greater power densities (capacity/area flooded-W/m 2 ), such as Itaipu, Xingo, Segredo and Miranda, have the best performance, well above thermo-power plants using state-of-the-art technology: combined cycle fueled by natural gas, with 50% efficiency. On the other hand, some hydro-power complexes with low-power density perform only slightly better or even worse than their thermo-power counterparts

    Hydro-peaking management can consistently alter fish populations, and particularly recruitment of diadromous species, like salmon. To progress in understanding the impacts and defining mitigation measures, it appears essential to combine long-term biological survey, hydrological analysis including hydro-peaks characterization, and hydro-morphologic approach. In a first time, a methodology for hydrological characterization of hydro-peaks is presented. Their diversity and high variability are illustrated. Then, we present operating experience on Maronne River, a tributary of the Dordogne River downstream Argentat affected by hydro-peaks of Hautefage scheme. Biological surveys and hydrologic and hydro-morphologic studies allowed a better understanding and a quantification of some biological impacts (redds dewatering, stranding-trapping of alevins), to support mitigation measures and to assess its effectiveness. The relevance of work on morphology, in addition to measures on flow management, is also illustrated. Some positive results have already been obtained. Studies on the Maronne River are pursued to achieve a really satisfactory situation. This example shows that the current knowledge does not allow, on a given stream, to pre-define mitigation measures and ensure their efficiency. This leads to advocate the setting up of similar approach on other river, to identify biological communities' responses depending on the characteristics of hydro-peaks and hydro-systems. (authors)

  18. MEA [Municipal Electric Association] declares opposition to 1991 Ontario Hydro rate increase

    International Nuclear Information System (INIS)

    1991-01-01

    In hearings before the Ontario Energy Board, the Municipal Electric Association (MEA) called for an average 1992 rate increase of 10.3%, lower than Ontario Hydro's revised figure of 10.4%, and a $129 million reduction in its operations, maintenance and administration budget. As it has been noted that Hydro pays considerably higher wages than the surrounding reference community, MEA recommended that the utility reduce and eventually eliminate the premium paid to employees, and also called for staff reductions and layoffs for 1991 and 1992. In the area of transmission reliability, MEA stated that Ontario Hydro's transmission maintenance is suffering at the expense of other priorities, and called for reorganizing its transmission plan to achieve target performance by 1996 rather than 1999. In 1991, only 65-70% of maintenance targets were being achieved. MEA also accused Hydro of deferring operational expenditures into deferment and capitalization, creating a false picture of the utility's financial condition. Also discussed at the hearing were the possible overestimating of the effects of Ontario Hydro's demand management programs, the possibility that a shift to time-of-use rates for industrial customers may increase demand, a downgrading of the province's and the utility's credit rating, and the unpleasant side effects of the non-utility generation program

  19. The future role of hydro-electricity in Sub-Saharan Africa

    1989-01-01

    Hydroelectric power currently supplies 56-93% of the electricity requirements of the different geographic areas of Sub-Saharan Africa and accounted for 73% of total requirements in 1980. The continent is richly endowed with hydro resources in all areas, with central Africa possessing the most abundant reserves. Existing installed hydro capacity is 13,500 MW and of the total technical resource of 290,000 MW, some 110,000 MW are estimated to constitute the potential that warrants investigation. The demand for electricity in the region is presently low and growing at 5-10%/y. It is projected to double from 47,000 GWh in 1980 to 110,000-170,000 GWh by the year 2000, and is likely to double again by 2020. Hydro reserves warranting investigation exceed the demand projected for the year 2000 by a ratio of over 3:1 and only 13 countries out of 36 have a ratio less than one. A large proportion of these reserves are estimated to be economic to develop relative to other means of power generation. The development of hydro resources should maintain the proportion of the demand met by hydro in the range of 60-75% well into the 21st century. The existing installed capacity is likely to be increased at the rate of 3,000-5,000 MW per decade to achieve this. Constraints on such increase include the large amounts of capital needed, environmental issues, the need to displace populations affected by flooding, and fluctuations in the oil price which make long-term planning uncertain. 5 refs., 1 fig., 11 tabs

    High index surfaces are of strong interest in todays research because of the possibility to grow low dimensional structures. It has for instance already been shown that the adsorption of Ga can induce the formation of 1D metal chains on Si(112) (cf. Snijders et al., PRB 72, 2005). In this work we investigated the clean Si(112) surface and the adsorption of In on Si(112) to establish an analogy to Ga/Si(112) using spot profile analyzing low energy electron diffraction (SPA-LEED). By means of reciprocal space mapping we determined the bare Si(112) surface to be decomposed into alternating (5512) and (111) facets in [1 anti 10] direction with (2 x 1) and (7 x 7) reconstruction, respectively (cf. Baski et al., Surf. Sci. 392, 1997). With SPA-LEED we were able to observe the decreasing intensity of the facet spots in-situ while depositing In on Si(112) and thus reveal the smoothening of the surface due to the deposition of In. At saturation coverage we found a (3.x1) reconstruction, where x is dependent on the deposition temperature and changes from x=7 at 400 C to x=5 at 500 C. This leads us to the assumption that the reconstruction is not incommensurate but a mixture of (3 x 1) and (4 x 1) building blocks, which is very similar to the super structure of Ga on Si(112).

    1999-01-01

    Full Text Available This paper examines the applicability of the Ritz method to multi-objective optimization of hydro-thermal systems. The algorithm proposed is aimed to minimize an objective functional that incorporates the cost of energy losses, the conventional fuel cost and the production of atmospheric emissions such as NO x and SO 2 caused by the operation of fossil-fueled thermal generation. The formulation includes a general layout of hydro-plants that may form multi-chains of reservoir network. Time-delays are included and the electric network is considered by using the active power balance equation. The volume of water discharge for each hydro-plant is a given constant amount from the optimization interval. The generic minimization algorithm, which is not difficult to construct on the basis of the Ritz method, has certain advantages in comparison with the conventional methods.

    This paper is on the problem of short-term hydro scheduling (STHS), particularly concerning a head-dependent hydro chain. We propose a novel mixed-integer nonlinear programming (MINLP) approach, considering hydroelectric power generation as a nonlinear function of water discharge and of the head. As a new contribution to earlier studies, we model the on-off behavior of the hydro plants using integer variables, in order to avoid water discharges at forbidden areas. Thus, an enhanced STHS is provided due to the more realistic modeling presented in this paper. Our approach has been applied successfully to solve a test case based on one of the Portuguese cascaded hydro systems with a negligible computational time requirement. (author)

  10. Hydro-Quebec : annual report 1998 : for today and tomorrow

    International Nuclear Information System (INIS)

    1999-01-01

    Hydro-Quebec is a publicly owned company with a single shareholder, the Quebec government. In 1998, the utility had over 31,400 MW in installed capacity, ranking it among North America's largest distributors of electrical energy. This report provides a review of progress and financial highlights including revenue, expenditure, financial expenses, net income, total assets, long term debt, shareholder's equity and the overall financial position of the utility. In 1998 sales totaled 161.4 TWh, with Quebec markets accounting for more than 88 percent and sales, outside Quebec accounting for 11.5 per cent. Three factors related to weather impacted the utility in 1998. The first was mild weather which brought down domestic and agricultural power consumption by 3 TWh compared with the average recorded in the past half-century. The second was low precipitation which caused Hydro-Quebec to turn to means other than hydroelectric generation to supply power to Quebec customers. These included start-up generation of the Tracy thermal generating station, reduction of sales on short-term markets outside Quebec, and electricity purchases on external markets. The third factor was the ice storm of January 1998, which caused significant damage to part of Hydro-Quebec's transmission and distribution systems. Throughout the year, Hydro-Quebec worked in reinforcing its power lines to prevent repetition of the devastation that occurred during the ice storm. In spite of the events of January 1998, the Utility remains committed to the growth and profitability orientations laid out in its Strategic Plan for 1998-2002. Significant progress was made in consolidating the Utility's position in international markets. Productive partnerships have been established with the Quebec Federation of Labour Solidarity Fund, and with Gaz de France. A network of international partners in a score of countries also has been developed. Hydro-Quebec has completed most of its preparations for Year 2000 readiness

    Radon ({sup 222}Rn) levels in air and water have been analyzed continuously for almost a year in Las Caldas de Besaya thermal spa, north Spain. Radon is a naturally occurring noble gas from the decay of radium ({sup 226}Ra) both constituents of radioactive uranium 238 series. It has been recognized as a lung carcinogen by the World Health Organization (WHO) and International Agency for Research on Cancer (IARC). Furthermore the Royal Decree R.D 1439/2010 of November, 2010 establishes the obligation to study occupational activities where workers and, where appropriate, members of the public are exposed to inhalation of radon in workplaces such as spas. Together with radon measures several physico-chemical parameters were obtained such as pH, redox potential, electrical conductivity and air and water temperature. The devices used for the study of the temporal evolution of radon concentration have been the RTM 2100, the Radon Scout and gamma spectrometry was complementarily used to determine the transfer factor of the silicone tubes in the experimental device. Radon concentrations obtained in water and air of the spa are high, with an average of 660 Bq/l and 2900 Bq/m{sup 3} respectively, where water is the main source of radon in the air. Radiation dose for workers and public was estimated from these levels of radon. The data showed that the thermal processes can control the behavior of radon which can be also influenced by various physical and chemical parameters such as pH and redox potential. - Highlights: • Radon in water is the major source of indoor air radon concentration in thermal facilities. • Radon in water has been used to characterize the origin of water used for treatments in a spa. • Preliminary dose assessment from radon exposure has been performed.

  14. Bearing Diagnostics of Hydro Power Plants Using Wavelet Packet Transform and a Hidden Markov Model with Orbit Curves

    Directory of Open Access Journals (Sweden)

    Gabriel Pino

    2018-01-01

    Full Text Available The contribution of a medium-sized hydro power plant to the power grid can be either at base load or at peak load. When the latter is the most common operation mode, it increases the start and stop frequency, intensifying the hydro turbine components’ degradation, such as the guide bearings. This happens due to more frequent operation in transient states, which means being outside the service point of the machines’ nominal condition, consisting of speed, flow, and gross head. Such transient state operation increases the runner bearings’ mechanical vibration. The readings are acquired during the runner start-ups and filtered by a DC component mean value and a wavelet packet transform. The filtered series are used to estimate the relationship between the maximum orbit curve displacement and the accumulated operating hours. The estimated equation associated with the ISO 7919-5 vibration standards establishes the sojourn times of the degradation states, sufficient to obtain the transition probability distribution. Thereafter, a triangular probability function is used to determine the observation probability distribution in each state. Both matrices are inputs required by a hidden Markov model aiming to simulate the equipment deterioration process, given a sequence of maximum orbit curve displacements.

    The complementarity of two renewable energy sources, namely hydro and wind, is investigated. We consider the diversification effect of wind power to reduce the risk of water inflow shortages, an important energy security concern for hydropower-based economic zones (e.g. Quebec and Norway). Our risk measure is based on the probability of a production deficit, in a manner akin to the value-at-risk, simulation analysis of financial portfolios. We examine whether the risk level of a mixed hydro-and-wind portfolio of generating assets improves on the risk of an all-hydro portfolio, by relaxing the dependence on water inflows and attenuating the impact of droughts. Copulas are used to model the dependence between the two sources of energy. The data considered, over the period 1958-2003, are for the province of Quebec, which possesses large hydro and wind resources. Our results indicate that for all scenarios considered, any proportion of wind up to 30% improves the production deficit risk profile of an all-hydro system. We can also estimate the value, in TW h, of any additional one percent of wind in the portfolio. (author)

    2004-01-01

    Radon ( 222 Rn) present in the spa facilities has been identified as an agent of additional radiation burden both for bathers and the working personnel. Although some researchers have been concentrated on the health impact of radon activity transient increases due to water flow of domestically used water, limited work has been reported on this effect in spa facilities. The aim of this work was to study the exposure both of bathers and working personnel due to water flow under working conditions in some thermal spas in Greece. The spas studied were built at two locations in Greece; Lesvos Island and the city of Loutra- Edipsou. The study was performed between 1999 and 2003. Measurements involved determination of radon concentration in the waters of the thermal spas, monitoring of radon and short-lived decay product activity (both in attached and unattached form) and coarse particles (> 500 nm). Water radon concentration was measured by Alpha Guard PQ2000Pro of Genitron GmbH equipped with an appropriate unit (Aquakit). Indoor radon activity was monitored by Alpha Guard PQ2000Pro and EQF3023 of Sarad GmbH which was also used for monitoring of radon short-lived decay product activity. Coarse particle concentration measurements were performed by a GRIMM 1.104 Portable Dust Monitor. Measurements indoors were performed in the treatment room and in the reception room, if existing, under working conditions. Several procedures for bath filling and pouring out of the treatment room, during the measurements, were studied. Radon concentrations of thermal waters were found to lie in the range 1 Bq.L -1 and 304 Bq.L -1 . Some of these concentrations may be considered as elevated. Elevated (about 2-6 kBq.m -3 ) indoor radon concentrations were measured in the treatment rooms of the spas of Polichnitos, Eftalou and Loutra Edipsou. This found to be in accordance to the high radon potential of these spas, as detected out of the measurements of their thermal waters. Concentration

    The early development of mini hydro development in Peninsular Malaysia was carried out by the National Electricity Board (NEB) and the projects developed in the 50s and 60s were Ulu Langat (Selangor), Sempam, Kg. Raja , Kuala Terla, and Robinson Falls (all in Pahang). In the 70s the main effort of hydropower development was concentrated on developing major hydropower projects not only to cater to the country increasing demand for electricity but also to the country needs for flood control. This development was feverishly carried out on the Perak River and the prohects built were Temenggor (384 MW), Bersia (72 MW), Kenering (20 MW), Sg Piah (70 MW) and the Kenyir (400 MW) project in Sungai Terengganu. In late 1970s, the government was keen to electrify the rural areas of Peninsular Malaysia and mini hydro power development was thought of as an option to provide electricity to these areas. The Mini Hydro Department of National Electricity Board (MHD) was then formed to undertake the task of planning, developing and implementing mini hydro projects to meet this government aspiration.

    This presentation reviewed public safety and historical practices at British Columbia (BC) Hydro. Historically, visitors were guided to safe locations at their facilities by visitor centres and public use management areas. Fences and booms were used to protect visitors from the more dangerous areas around the facility. This presentation also described the features of the safety management plans that BC Hydro has in place for each of its 41 facilities. The safety management plans are approved by the plant managers; they have common controls such as fences and signs; and there are excellent maps defining the danger areas. New risks that were identified were also presented. The next steps for BC Hydro include test driving the draft Canadian Dam Association guidelines for the Aberfeldie Dam; a new powerhouse to reduce overtopping of the dam during the spring; and continuing with public safety hazards and controls such as bow-ties. figs.

  4. Summary of Ontario Hydro's 1990-91 zebra mussel research program

    Claudi, R.; Wiancko, P.M.

    1992-01-01

    Ontario Hydro is the principal supplier of electricity to the Province of Ontario. It serves 3.6 million customers, with an inservice capacity of 28,200 MW. Ontario Hydro has seven fossil, five nuclear, and four hydraulic stations in the Great Lakes Basin and surrounding watershed. In addition, there are another 60 inland hydraulic stations and numerous dams. As the largest single user of raw water from the Great Lakes Basin, Ontario Hydro recognized the need to control zebra mussels early in 1989. At that time, very little was known in North America about the zebra mussel life cycle and potential impact. European utilities were consulted, but as we now know, zebra mussels are not perceived to be a problem in Europe at this time. To satisfy the immediate need for control, chlorination was identified as the most effective interim measure to prevent the fouling of systems which draw water from the aquatic environment. Due to the current regulatory environment, this solution is considered short term and Ontario Hydro was compelled to initiate a comprehensive research effort aimed at providing alternative methods of control. Most of the research effort during 1990, was methods of control. Most of the research effort during 1990, was directed towards this goal. Many alternative control measures, both chemical and nonchemical were considered. Also considered were the potential effects of the control measures and zebra mussels on station operations. A multidisciplinary team involving aquatic biologists, chemists, corrosion specialists, and civil and mechanical engineers from the various departments of Ontario Hydro was asked to address the problem. Some of the research also involved collaborative studies with universities, US utilities, American Water Works Association, and Canadian industries. Following is a summary of the research effort in 1990, and a preview of the research underway in 1991

    Anthocyanins are natural pigments that accumulate only in light-grown and not in dark-grown Arabidopsis plants. Repression of anthocyanin accumulation in darkness requires the CONSTITUTIVELY PHOTOMORPHOGENIC1/SUPPRESSOR OF PHYA-105 (COP1/SPA) ubiquitin ligase, as cop1 and spa mutants produce anthocyanins also in the dark. Here, we show that COP1 and SPA proteins interact with the myeloblastosis (MYB) transcription factors PRODUCTION OF ANTHOCYANIN PIGMENT1 (PAP)1 and PAP2, two members of a small protein family that is required for anthocyanin accumulation and for the expression of structural genes in the anthocyanin biosynthesis pathway. The increased anthocyanin levels in cop1 mutants requires the PAP1 gene family, indicating that COP1 functions upstream of the PAP1 gene family. PAP1 and PAP2 proteins are degraded in the dark and this degradation is dependent on the proteasome and on COP1. Hence, the light requirement for anthocyanin biosynthesis results, at least in part, from the light-mediated stabilization of PAP1 and PAP2. Consistent with this conclusion, moderate overexpression of PAP1 leads to an increase in anthocyanin levels only in the light and not in darkness. Here we show that SPA genes are also required for reducing PAP1 and PAP2 transcript levels in dark-grown seedlings. Taken together, these results indicate that the COP1/SPA complex affects PAP1 and PAP2 both transcriptionally and post-translationally. Thus, our findings have identified mechanisms via which the COP1/SPA complex controls anthocyanin levels in Arabidopsis that may be useful for applications in biotechnology directed towards increasing anthocyanin content in plants. © 2013 The Authors The Plant Journal © 2013 John Wiley & Sons Ltd.

  8. Hydro-Quebec and energy efficiency

    International Nuclear Information System (INIS)

    1990-01-01

    There is growing awareness that energy efficiency is both profitable and environmentally beneficial. In this year's Development Plan, Hydro-Quebec is proposing an Energy Efficiency Project made up of marketing programs designed for all markets throughout the final decade of the 20th century. This Project will have two aspects: energy efficiency and consumption management. Hydro-Quebec aims to reach an energy-efficiency level of 12.9 terawatt hours per year by 1999, fully 55% of its 23-terawatt hour potential. Over the next 10 years the utility intends to spend $1.8 billion for this purpose. Cumulative anticipated energy savings should be in the vicinity of 70 terawatt hours for the coming decade, and more than 130 terawatt hours for the first decade of the next century. Of the overall goal of 12.9 terawatt hours for Horizon 1999, energy savings of 9.0 terawatt hours should be the direct result of this year's proposed marketing programs, and will account for the bulk of anticipated investments. The remaining 3.9 terawatt hours will be gained as customers acquire better electrical appliance and accessory (household appliances, home insulation) buying habits

    A provincial Crown corporation, Manitoba Hydro serves approximately 502,000 customers throughout Manitoba with electric energy, and provides natural gas service to 251,000 customers in several communities in southern Manitoba. In addition, Manitoba Hydro exports electricity to electric utilities and marketers in the mid-western United States, Ontario, and Saskatchewan. In 2002, Winnipeg Hydro was purchased from the City of Winnipeg. Records were broken for historical peak demand for electricity (24 February 2003) and natural gas (22 January 2003). A study of wind power generation was launched, with seven sites being monitored. A Power Smart program focusing on geothermal heat pump systems also offered assistance to Manitoba homeowners. Successful conversion of the Selkirk Generating Station from coal to natural gas was achieved. In Brandon, a 260 mega watt (MW) natural gas combustion turbine plant was opened. Over $29 million in loans were issued to customers under the Home Comfort and Energy Savings Program. Electricity rates for residential customers remained unchanged, as did those for large industrial customers. Approval was received by the National Energy Board to export 500 MW of electricity to Northern States Power. A new international interconnection was brought into service in November 2002 between Glenboro, Manitoba and Harvey, North Dakota. The ISO 14001 international certification for environmental management systems was awarded to Manitoba Hydro. tabs., figs

    A number of molecular typing methods have been developed for characterization of Staphylococcus aureus isolates. The utility of these systems depends on the nature of the investigation for which they are used. We compared two commonly used methods of molecular typing, multilocus sequence typing (MLST) (and its clustering algorithm, Based Upon Related Sequence Type [BURST]) with the staphylococcal protein A (spa) typing (and its clustering algorithm, Based Upon Repeat Pattern [BURP]), to assess the utility of these methods for macroepidemiology and evolutionary studies of S. aureus in the United States. We typed a total of 366 clinical isolates of S. aureus by these methods and evaluated indices of diversity and concordance values. Our results show that, when combined with the BURP clustering algorithm to delineate clonal lineages, spa typing produces results that are highly comparable with those produced by MLST/BURST. Therefore, spa typing is appropriate for use in macroepidemiology and evolutionary studies and, given its lower implementation cost, this method appears to be more efficient. The findings are robust and are consistent across different settings, patient ages, and specimen sources. Our results also support a model in which the methicillin-resistant S. aureus (MRSA) population in the United States comprises two major lineages (USA300 and USA100), which each consist of closely related variants.

    Small hydro is a renewable source of energy that is economically and technically viable. This article described China's investment in small-scale hydroelectric power plants in 1,600 remote communities. Seventy per cent of China's small hydro power stations are concentrated in remote impoverished communities. These power stations provide electricity to 300 million people in China, where half of the territories, one third of the districts and towns, and one quarter of the population depend primarily on this energy source for their electricity needs. The first power station was built in the province of Yunnan in 1912, but the real development of small hydro occurred after 1950, and can be divided into three phases. Phase 1 occurred before 1980 when small hydro power stations concentrated on providing electricity for lighting in rural areas as well as for transforming agriculture and irrigation. For many decades following the foundation of the Republic of China, rural areas did not have access to electricity or had serious shortages of electricity. In order to ensure electricity in isolated and remote areas, the Chinese government requested that local authorities build and exploit small hydro where conditions were favourable, and this while respecting water resources. Phase 2 occurred between 1980s and 1990s, with a focus on improving the performance of small hydro power stations to include electricity provisions for local enterprises. During phase 2, small hydro became a tool for dynamic rural development for farmers to increase their revenues. The latest phase in small hydro development has also helped reduce poverty and develop local economies, but in addition, it plays a role in the long term protection of ecosystems, the environment and rural modernization. Today 660,000 people work for small power stations and most are employed locally. Replacing firewood with electricity has saved 130,000 hectares of forested land and helped protect ecosystems. Small

    The purpose of this study was to develop a checklist of items that describes and measures the quality of reports of interventional trials assessing spa therapy. The Delphi consensus method was used to select the number of items in the checklist. A total of eight individuals participated, including an epidemiologist, a clinical research methodologist, clinical researchers, a medical journalist, and a health fitness programmer. Participants ranked on a 9-point Likert scale whether an item should be included in the checklist. Three rounds of the Delphi method were conducted to achieve consensus. The final checklist contained 19 items, with items related to title, place of implementation (specificity of spa), care provider influence, and additional measures to minimize the potential bias from withdrawals, loss to follow-up, and low treatment adherence. This checklist is simple and quick to complete, and should help clinicians and researchers critically appraise the medical and healthcare literature, reviewers assess the quality of reports included in systematic reviews, and researchers plan interventional trials of spa therapy.

    2004-07-01

    BC Hydro's installed generation capacity as of March 31, 2003 was 11,103 MW, of which 90 per cent was hydro power, 9 per cent was gas-fired and 1 per cent was non-integrated. The hydroelectric plants belong to one of three groups, the Peace River, Columbia River or small hydro which includes small to moderate sized-plants. Small hydro is controlled by hydrologic regime and storage limitations rather than by system requirements. The installed capacity for the 4 plants on the Columbia River totals 4,722 MW. The installed capacity at the 2 plants on the Peace River totals 3,424 MW. Both watersheds are subject to interior climate conditions with significant inflows from snowmelt and rainfall runoff. This presentation addressed the issue of mid-term hydro scheduling and its impact on markets. For the past 15 years, BC Hydro has used the marginal cost model for electricity trade and for operations planning. The model considers system loads and resources, and maximizes the expected net revenue over a planning horizon of 6 years. A marginal value of water stored in the Williston Reservoir has been established using the marginal cost model. The affect of weather, natural gas prices and water supply on hydro generation was also discussed. It was noted that information on spot market electricity prices has significantly improved since the electric power industry was deregulated in 1996. tabs., figs.

    Water is an indispensable necessity of life for people in the whole world. In central Asia, water is the key factor for economic development, but is already a narrow resource in this region. In fact of climate change, the water problem handling will be a big challenge for the future. The regional research Network "Central Asia Water" (CAWa) aims at providing a scientific basis for transnational water resources management for the five Central Asia States Kyrgyzstan, Uzbekistan, Tajikistan, Turkmenistan and Kazakhstan. CAWa is part of the Central Asia Water Initiative (also known as the Berlin Process) which was launched by the Federal Foreign Office on 1 April 2008 at the "Water Unites" conference in Berlin. To produce future scenarios and strategies for sustainable water management, data on water reserves and the use of water in Central Asia must therefore be collected consistently across the region. Hydro-meteorological stations equipped with sophisticated sensors are installed in Central Asia and send their data via real-time satellite communication to the operation centre of the monitoring network and to the participating National Hydro-meteorological Services.[1] The challenge for CAWa is to integrate the whole aspects of data management, data workflows, data modeling and visualizations in a proper design of a monitoring infrastructure. The use of standardized interfaces to support data transfer and interoperability is essential in CAWa. An uniform treatment of sensor data can be realized by the OGC Sensor Web Enablement (SWE) , which makes a number of standards and interface definitions available: Observation & Measurement (O&M) model for the description of observations and measurements, Sensor Model Language (SensorML) for the description of sensor systems, Sensor Observation Service (SOS) for obtaining sensor observations, Sensor Planning Service (SPS) for tasking sensors, Web Notification Service (WNS) for asynchronous dialogues and Sensor Alert Service

    2015-12-01

    Full Text Available Lumbar spondylarthrosis is a degenerative disease that affects the joint structures of the lumbar spine. In the course of time, numerous studies on the role of hydro-kinesiotherapy in the treatment of lumbar spondylosis have been conducted. The aim of this research is motivated by the significantly high number of patients with chronic pain in the lumbar spine due to lumbar spondylosis, as well as by the negative impact on their quality of life through the impairment of the activities of daily living. The prospective longitudinal study was carried out at the Clinical Rehabilitation Hospital Cluj-Napoca. The study included 35 patients with chronic low back pain and mobility limitation in the lumbar spine. The patients were assigned to two groups: the study group formed by 20 patients and the control group consisting of 15 patients aged between 40-70 years. The treatment of the patients included in the study was performed over a two week period and consisted of a hydro-kinesiotherapy program, for the patients of the study group, the duration of a treatment session being 40 minutes. Both the subjects of the study group and of the control group also benefited from sedative massage of the lumbosacral spine, kinesiotherapy, laser therapy of the lumbar spine. The patients were evaluated using Schober’s test, the Visual Analogue Scale, the Oswestry index. These evaluation methods were applied to the patients of both groups at the beginning of the rehabilitation programs and after two weeks. The results of the study demonstrated the therapeutic efficacy of the medical rehabilitation programs that included hydro-kinesiotherapy programs. The patients of both groups had improvements through a decrease of lumbar pain, an increase in lumbar spine mobility, as well as in the patients’ ability to organize themselves in the activities of daily living. However, the patients of the study group, with a hydro-kinesiotherapy program performed for two weeks, had

    Methicilin resistance Staphylococcus aureus (MRSA) infections are the major challenges in hospitals, especially in the burn units. The use of molecular typing methods is essential for tracking the spread of S. aureus infection and epidemiological investigations. The aim of this study was to find the profile of the spa types and also the prevalence of each SCCmec type of S. aureus strains in a central burn hospital in southwest of Iran. A total of 81 non-duplicate S. aureus were isolated from burn patients between April 2011 and February 2012. The susceptibility of the isolates against 13 different antibiotics was tested by disk agar diffusion (DAD) method. MRSA strains were identified by amplification of mecA gene. Multiplex-polymerase chain reaction (PCR) technique was used to determine the SCCmec types of MRSA strains and all the S. aureus isolates were typed by spa typing method. Detection of mecA gene showed that 70 (86.4%) of the isolates were MRSA. The highest rate of resistance was observed for penicillin (97.5%) and erythromycin (77.8%). None of the isolates were resistant to vancomycin. Sixty-seven of the 70 MRSA isolates harbored only SCCmec type III and three untypeable isolates. Five different spa types were detected. The most common spa types were t037 (42.5%) and t631 (34.5%) and were only found in MRSA isolates. Only SCCmec type III was found in burn patients which emphasizes the HA-MRSA origin of these strains. Only five different spa types identified in this study are in accordance with one SCCmec type which indicates that a limited number of bacterial colons are circulated in the burn unit in this hospital. © 2015 APMIS.

    In spite of producing no atmospheric pollutants, hydroelectric power plants often go unrecognized as a unique provider of clean, efficient, low-cost energy. A concerted effort is needed to ensure that these attributes are fully accounted for when considering the uses and benefits of available water resources. Relicensing reviews and other regulatory activities associated with continued operation of hydro generation projects have drawn increased attention to hydro resources. This attention has typically resulted in imposition of conditions having a substantial cost impact without, necessarily, reflecting a full appreciation of the resource's benefits and attributes. With the extensive countrywide effort in relicensing and regulation, there is an opportunity to collect and compile lessons learned. This is particularly true with respect to preferred practices, technologies, and techniques applicable to required studies and mitigation measures. Such compilation will enable the industry and related stakeholders to improve quality and effectiveness while reducing costs of relicensing and mitigation for continued hydro operations. As a technology leader for the industry, EPRI is in a unique position to identify and document these techniques and practices. This report comprises the proceedings of the hydro licensees workshop. Fifteen licensee representatives with recent or current involvement in the relicensing process gathered at this workshop and shared their experiences, both good and bad. Support was strong among attendees for EPRI's effort to collect and compile these, along with the experiences of others, into a guidebook of accepted practices. Initial workshop findings were used in the second workshop to solicit buy-in from agencies and NGOs to the need for--as well as proposed scope of--a compendium of preferred practices

    Despite having had a deregulated electricity market in Sweden for over ten years we still need to increase our understanding as to how deregulated electricity markets actually work and how possible problems are to be solved. One question that is always in focus is if the competition between generators in the Nordic electricity market really works the way it was intended. Many argue that the concentration in ownership of generation plants already has gone too far. Together with joint ownership in nuclear facilities and barriers for entrance, critics say that this has resulted in higher electricity prices than necessary. In this report different methods to (ex ante) study potential possibilities for generating firms to influence the electricity price (market power) and (ex post) discover possible manipulation through analysing the spot price and other observed factors on the electricity market are analysed. The purpose of the longer underlying paper is to give a comprehensive treatment of the electricity market with storage, i.e. hydro power, with an auction market organisation and to test the models on the Nordic market in order to explore the explanatory power of auction market theory and the theory of contestable market. The main theoretical effort in the paper concerns auction theory with inventories. The paper develops an inter-temporal auction model of a thermal-hydro power market. Parallel to the derivation of the basic equations a numerical model is developed in order to illustrate the results of the model. Section 2 of the present paper summarizes the basic equations (derived in the longer paper) for an inter-temporal auction thermal-hydro market. Section 3 contains the illustrations of solutions to equations for some stylized markets. In section 4 the auction model is tested on the Nordic market

  12. Implications of the Bangor Hydro decision on FERC relicensings

    In the next 15 years, over 400 existing nonfederal dams will require new licenses by the Federal Energy Regulatory Commission (FERC) in order to continue operations. In many cases, state or federal agencies have a unique opportunity to condition the hydropower licenses to protect environmental values. In 1996, the Court of Appeals for the District of Columbia Circuit issued an opinion striking down a mandatory license condition imposed by the U.S. Department of the Interior in a FERC relicensing. The case, Bangor Hydro-Electric Company v.Federal Energy Regulatory Commission, is instructive for agencies regarding the procedures to be followed in imposing mandatory FERC licensing conditions in the future. After Bangor Hydro, agencies should: (1) support their decisions by substantial evidence in the FERC record, (2) request applicant studies to support agency decisions and allow public comment on the decisions as a means to test the facts and analysis, and (3) consider intervening in a case to defend the condition on appeal. Bangor Hydro also raises, but does not decide, the issue of whether the agency imposing the mandatory condition should engage in balancing the economics of the hydropower project with the public resources affected by the project.

  13. In the spotlight: New hydro development in North America

    1992 was a year of progress for many segments of the hydropower industry as developers worked to bring new projects on line. This industry overview features several of these projects and offers a preview of 1993 activity. The only operating privately owned hydroelectric project in Texas. The largest hydro plant in the province of Manitoba. The world's largest submersible hydroturbine-generator. These projects and others-completed and placed in service in 1992-can claim a special place in the history books. For each of the 31 hydro projects in North America that began operating in 1992, there's a unique story to tell. Each called upon the time, talent, commitment, ingenuity, and perseverance of those involved in their development. In aggregate, these projects contribute nearly 3,800 MW of clean, renewable electrical capacity that can be used efficiently and cost-effectively to help meet the power demands of customers in the US and Canada. Utilities, state agencies, municipalities, and independent power developers played roles in developing new hydro in 1992. We offer a sampling of their work to illustrate progress made in the past year

  19. B.C. Hydro drops Duke Point

    The abandonment of the proposed natural gas-fired Duke Point Power Project on Vancouver Island was discussed. It was suggested that the continuing appeal process increases the risk that the plant will not be built in time. The news followed a decision by the British Columbia (BC) Court of Appeal to hear an appeal of the project by a number of intervenors. Over $170 million has been spent on the project to date. The decision will impact the BC treasury, as the amount is being deducted from the dividends that BC Hydro would have paid to the government. A coalition of individuals and environmental groups, as well as local industry, are opposed to the plant on the basis of increased greenhouse (GHG) emissions and higher natural gas prices. The project would have required a natural gas pipeline to be built under Georgia Strait. The project was thought necessary due to the deteriorating condition of high voltage direct current cables running under the strait. BC Hydro's fallback plan for the island is load reduction. A new transmission line is also planned

  20. Liquid assets: factors contributing to the development of small hydro in China

    The rapid growth of small hydro capacity in China is reviewed. At present, the annual generation from rural small hydropower in China equates with the saving of 44 million tonnes of coal, or the emission of 110 million tonnes of carbon dioxide. Other environmental advantages such as a reduction in wood burning, reduced logging and therefore reduced soil erosion, are mentioned. Energy-starved China stood to gain much from the development of small hydro systems and government policy has been supportive in terms of relatively low tax rates and low interest loans. It is expected that due to the rapid economic growth in China, small-scale hydro will maintain its present level of development and continue to be promoted in a sound and rational manner. (author)
