    The System for Prediction of Environmental Emergency Dose Information called 'SPEEDI' provides realistic estimate of radiation concentration and dose assessment that may result from an atmospheric release of radioactive materials. SPEEDI uses advanced computer-based data processing and data communication system for atmospheric dispersion calculation to derive radiation consequence assessment with the concerned meteorological data and the source term information. SPEEDI has been developed since 1980 by Japan Atomic Energy Research Institute(JAERI), Meteorological Research Institute following to the lessons learned from the accident in 1979 at Three Mile Island, USA. Nuclear Safety Technology Center(NUSTEC) has been constructing a nationwide data communication network that links STA and relevant local governments since 1986. The network now comprises 13 local stations in local governments while the Science and Technology Agency(STA) functions as the command center for SPEEDI in case of emergency. In Japan, the conventional simplified Gaussian plume model has been used for emergency radiation dose estimation however, SPEEDI was recognized as the authorized method for it in 'Emergency Environmental Radiation Monitoring Criteria' and 'Off-site Emergency Planning and Preparedness for Nuclear Power Plants' in 1992. The role of SPEEDI is now far the more important. Local governments are now conducting nuclear emergency exercises almost every year incorporating the information of SPEEDI in their scenarios.

    The range and concentration of the radioactive plume discharged during an accident would depend on the local topography and the meteorological conditions, e.g., wind direction and velocity, precipitation, and atmospheric stability. Considering these situations, SPEEDI, a computational code system, predicts the concentration of radioactive materials in the atmosphere and on the ground surface, air absorbed dose rate, external exposure dose and internal dose by inhalation. We introduced advanced SPEEDI (A-SPEEDI) models to solve some problems that were included in the conventional SPEEDI. New models have been developed as successor models of the conventional SPEEDI by Japan Atomic Energy Research Institute. The major improvement is the introduction of a prognostic meteorological model PHYSIC to A-SPEEDI. PHYSIC performs the regional meteorological forecasts using nationwide meteorological observation data and meteorological forecast data RSM provided by the Japan Meteorological Agency (JMA) for the initial condition and the boundary conditions around a nuclear facility. Atmospheric dispersion and dose calculation models were upgraded to improve the prediction performance as well. By introducing A-SPEEDI models, a long-term meteorological forecast such as following 24 hours is possible, and the prediction performance is improved under various meteorological conditions.

  3. SPEEDY: An Eclipse-based IDE for invariant inference

    Full Text Available SPEEDY is an Eclipse-based IDE for exploring techniques that assist users in generating correct specifications, particularly including invariant inference algorithms and tools. It integrates with several back-end tools that propose invariants and will incorporate published algorithms for inferring object and loop invariants. Though the architecture is language-neutral, current SPEEDY targets C programs. Building and using SPEEDY has confirmed earlier experience demonstrating the importance of showing and editing specifications in the IDEs that developers customarily use, automating as much of the production and checking of specifications as possible, and showing counterexample information directly in the source code editing environment. As in previous work, automation of specification checking is provided by back-end SMT solvers. However, reducing the effort demanded of software developers using formal methods also requires a GUI design that guides users in writing, reviewing, and correcting specifications and automates specification inference.

    The SPEEDI system is a computational code system to predict the radiological dose due to the plume released in a nuclear accident in Japan. This paper describes the SPEEDI's application to the Chernobyl reactor accident for the estimation of the movement of plume and the release rate of radioactive nuclides into the environment. The predicted results on the movement of plume agreed well with the monitoring data in Europe. The estimated results on the release rate showed that half of the noble gas inventory, about 5 % of the iodine inventory and about 3 % of the cesium inventory are released into the environment within 24 hours.

    body. The crista serves as a rudder and propeller for the swimming organism. It is interesting to compare here the elastic and regularly waved flagella of certain bacteria and spirochetes; it is possible that the crista of Cristispira is a highly modified form of flagella. The nature of the substance which stains dark blue with Giemsa's stain is not known, but it does not give a chromatin reaction. By Heidenhain's iron-hematoxylin method it takes a dark grayish tint, similar to the cell wall or crista, which are also dark gray. This substance was regarded by Gross and Zuelzer as volutin, which is of nutritive origin. It is probable that there are also embedded within it minute chromidial elements. Multiplication is by transverse fission. Cristispira balbianii is parasitic and does not survive more than a few days in ordinary sea water emulsion, even at its optimum temperature. In its natural habitat, or the crystalline style, it is usually pure, but is sometimes found in association with a tiny spiral organism (Spirillum ostreae). The cristispiras in the styles seem to diminish rapidly when oysters are collected from their beds and transferred elsewhere; oysters kept in tanks or cars for several days do not contain the cristispiras, and in opened oysters the styles disappear promptly at room temperature. All efforts to cultivate this organism have failed.

    A numerical simulation system SPEEDI-MP has been developed to apply for various environmental studies. SPEEDI-MP consists of dynamical models and material transport models for the atmospheric, terrestrial, and oceanic environments, meteorological and geographical database for model inputs, and system utilities for file management, visualization, analysis, etc., using graphical user interfaces (GUIs). As a numerical simulation tool, a model coupling program (model coupler) has been developed. It controls parallel calculations of several models and data exchanges among them to realize the dynamical coupling of the models. A coupled model system for water circulation has been constructed with atmosphere, ocean, wave, hydrology, and land-surface models using the model coupler. System utility GUIs are based on the Web technology, allowing users to manipulate all the functions on the system using their own PCs via the internet. In this system, the source estimation function in the atmospheric transport model can be executed on the grid computer system. Performance tests of the coupled model system for water circulation were also carried out for the flood event at Saudi Arabia in January 2005 and the storm surge case by the hurricane KATRINA in August 2005.

  11. SPEEDY RECOVERY OF DAMAGED DIGITAL PHOTOGRAPHS USING MULTI STRUCTURE MORPHOLOGY

    Directory of Open Access Journals (Sweden)

    D. Jemi Florinabel

    2011-11-01

    Full Text Available A speedy recovery of damaged digitized photographs based on orientation driven multi structure morphology is proposed. The recovery order plays an important factor for human visualization and hence it is guided by the orientation of edges at the surrounding known regions of the missing domain. The image is edge detected by thresholding the image gradient along the eight possible orientations. These eight edge images are represented as eight edge planes. The edge-plane-sliced information is used twice manifold for reconstructing the regions within the missing part, as well as for guiding the integration that follows. The damaged regions are morphologically eroded using the structuring elements of corresponding orientations dictated by the edge-planes. The resultant filled image is obtained using local isotopic driven integration. The novelty of our approach is to explicitly specify the direction of filling herby ensuring ease in convergence in different orientations and then streamlining the process to guarantee complete and natural look. By implementing region-filling through morphological erosion, several pixels instead of one can be restored at every inpainting step, making the method faster than many traditional texture synthesis inpainting algorithms and successfully recovers images with better Peak Signal to Noise ratios even for massive damages.

    This study suggests a methodology of severe accident mitigation support with speediness and credibility. Using this methodology, the severe accident is automatically identified based on the information credibility check. And then, proper mitigation function, available mitigation routes, and an optimal mitigation path are automatically suggested. The basic logic of the information credibility is based on environmental evaluation, historical evaluation and some conventional methods such as redundancy and diversity comparison of instruments. To identify the available mitigation routes, availability of paths and components, source status, process limitation, expected adverse effect, and mitigation capability of the path are automatically were evaluated. Among the available routes, the optimal mitigation path was finally suggested based on the path priority criteria and physical relationship

    Data gathering is a key operator for applications in wireless sensor networks; yet it is also a challenging problem in mobile sensor networks when considering that all nodes are mobile and the communications among them are opportunistic. This paper proposes an efficient data gathering scheme called ADG that adopts speedy mobile elements as the mobile data collector and takes advantage of the movement patterns of the network. ADG first extracts the network meta-data at initial epochs, and calculates a set of proxy nodes based on the meta-data. Data gathering is then mapped into the Proxy node Time Slot Allocation (PTSA) problem that schedules the time slots and orders, according to which the data collector could gather the maximal amount of data within a limited period. Finally, the collector follows the schedule and picks up the sensed data from the proxy nodes through one hop of message transmissions. ADG learns the period when nodes are relatively stationary, so that the collector is able to pick up the data from them during the limited data gathering period. Moreover, proxy nodes and data gathering points could also be timely updated so that the collector could adapt to the change of node movements. Extensive experimental results show that the proposed scheme outperforms other data gathering schemes on the cost of message transmissions and the data gathering rate, especially under the constraint of limited data gathering period.

    2010-01-01

    A numerical simulation system named SPEEDI-MP for environmental studies has been developed by the Japan Atomic Energy Agency. In this development, the national emergency response system SPEEDI, which predicts atmospheric dispersion and environmental impacts of radionuclides from nuclear facilities after an accident, is extended to be able to deal with various environments from atmospheric to terrestrial and oceanic environments. In SPEEDI-MP, this kind of complex simulation was realized by introducing a model coupler. Calculations of component models are carried out by different processors of parallel computers and the coupler controls these processes and handles data exchange among component models. Performance of the coupled model has been demonstrated in simulations of the storm surge caused by Hurricane Katrina in August 2005 and flash floods after heavy rainfall in Saudi Arabia. The development toward inclusion of substances of environmental concern into the model system is currently under way. As the first step of this development, the incorporation of tritium as a hazardous material worked well. (author)

  20. Study of the global and regional climatic impacts of ENSO magnitude using SPEEDY AGCM

    2017-01-01

    ENSO is considered as a strong atmospheric teleconnection that has pronounced global and regional circulation effects. It modifies global monsoon system, especially, Asian and African monsoons. Previous studies suggest that both the frequency and magnitude of ENSO events have increased over the last few decades resulting in a need to study climatic impacts of ENSO magnitude both at global and regional scales. Hence, to better understand the impact of ENSO amplitude over the tropical and extratropical regions focussing on the Asian and African domains, ENSO sensitivity experiments are conducted using ICTPAGCM (‘SPEEDY’). It is anticipated that the tropical Pacific SST forcing will be enough to produce ENSO-induced teleconnection patterns; therefore, the model is forced using NINO3.4 regressed SST anomalies over the tropical Pacific only. SPEEDY reproduces the impact of ENSO over the Pacific, North and South America and African regions very well. However, it underestimates ENSO teleconnection patterns and associated changes over South Asia, particularly in the Indian region, which suggests that the tropical Pacific SST forcing is not sufficient to represent ENSO-induced teleconnection patterns over South Asia. Therefore, SST forcing over the tropical Indian Ocean together with air–sea coupling is also required for better representation of ENSO-induced changes in these regions. Moreover, results obtained by this pacemaker experiment show that ENSO impacts are relatively stronger over the Inter-Tropical Convergence Zone (ITCZ) compared to extratropics and high latitude regions. The positive phase of ENSO causes weakening in rainfall activity over African tropical rain belt, parts of South and Southeast Asia, whereas, the La Niña phase produces more rain over these regions during the summer season. Model results further reveal that ENSO magnitude has a stronger impact over African Sahel and South Asia, especially over the Indian region because of its significant

    1985-10-01

    SPEEDI, a computer code system for prediction of environmental doses from radioactive materials accidentally released from a nuclear plant has been developed to assist the organizations responsible for an emergency planning. For realistic simulation, have been developed a model which statistically predicts the basic wind data and then calculates the three-dimensional mass consistent wind field by interpolating these predicted data, and a model for calculation of the diffusion of released materials using a combined model of random-walk and PICK methods. These calculation in the system is carried out in conversational mode with a computer so that we may use the system with ease in an emergency. SPEEDI has also versatile files, which make it easy to control the complicated flows of calculation. In order to attain a short computation time, a large-scale computer with performance of 25 MIPS and a vector processor of maximum 250 MFLOPS are used for calculation of the models so that quick responses have been made. Simplified models are also prepared for calculation in a minicomputer widely used by local governments and research institutes, although the precision of calculation as same with the above models can not be expected to obtain. The present report outlines the structure and functions of SPEEDI, methods for prediction of the wind field and the models for calculation of the concentration of released materials in air and on the ground, and the doses to the public. Some of the diffusion models have been compared with the field experiments which had been carried out as a part of the SPEEDI development program. The report also discusses the reliability of the diffusion models on the basis of the compared results, and shows that they can reasonably simulate the diffusion in the internal boundary layer which commonly occurs near the coastal region.

    Full Text Available The failure of animals to fit all life-cycle stages into an annual cycle could reduce the chances of successful breeding. In some cases, non-optimal strategies will be adopted in order to maintain the life-cycle within the scope of one year. We studied trade-offs made by a High Arctic migrant shorebird, the red knot Calidris canutus islandica, between reproduction and wing feather molt carried out in the non-breeding period in the Dutch Wadden Sea. We compared primary molt duration between birds undertaking the full migratory and breeding schedule with birds that forego breeding because they are young or are maintained in captivity. Molt duration was ca. 71 days in breeding adults, which was achieved by an accelerated feather replacement strategy. Second-year birds and captive adults took ca. 22% and 27% longer, respectively. Second-year birds start molt in late June, more than four weeks before captive adults, and almost seven weeks before adults that return from breeding in late July-August. Adults finish molt in October when steeply increasing thermostatic costs and reductions in food availability occur. Primary molt duration was longer in female than in male knots (all ages, which was accordance with the somewhat larger body size of females. Since fast growth leads to lower quality feathers, the speedy wing molt shown by Arctic-breeding birds may represent a time constraint that is an unavoidable and routine cost of reproduction. So far it was hypothesized that only birds over 1 kg would have difficulty fitting molt within a year. Here we show that in birds an order of magnitude smaller, temporal imperatives may impose the adoption of non-optimal life-cycle routines in the entire actively breeding population.

    Status of the reforms in Lithuania's energy sector and preparation of updated Energy Strategy is presented in this article. The new Strategy has been worked out considering the conclusions of different studies as well as the changes that have taken place in Lithuania and restructuring of its energy sector, the guidelines of the European Union. The principal objectives of the country's energy sector consists in reliable and safe energy supply with minimum expenses, increasing efficiency of energy utilisation, introducing principles of market economy within the sector, reducing environmental impacts, preparing Lithuania's energy sector for integration into the EU. In the field of nuclear energy the top priority is to ensure the safety of Ignalina NPP. Ignalina NPP will only be operated if and as long as it is safe. Two most likely scenarios for the future operation of Ignalina NPP are analysed in the draft Strategy. According to scenario 1, reactor 1 and 2 are to be operated half of the design service life, until 2005 and 2010 respectively, i.e. until the gap between the graphite and fuel channels reaches the critical margin. In accordance with the second scenario, the fuel channels are to be replaced as envisaged in the design, after which the reactors may be operated for another 10 - 15 years

    BACKGROUND: Universal access to health care is valued in Canada but increasing wait times for services (eg, cardiology consultation) raise safety questions. Observations suggest that deficiencies in the process of care contribute to wait times. Consequently, an outpatient clinic was designed for Ensuring Access and Speedy Evaluation (Cardiac EASE) in a university group practice, providing cardiac consultative services for northern Alberta. Cardiac EASE has two components: a single-point-of-entry intake service (prospective testing using physician-approved algorithms and previsit triage) and a multidisciplinary clinic (staffed by cardiologists, nurse practitioners and doctoral-trained pharmacists). OBJECTIVES: It was hypothesized that Cardiac EASE would reduce the time to initial consultation and a definitive diagnosis, and also increase the referral capacity. METHODS: The primary and secondary outcomes were time from referral to initial consultation, and time to achieve a definitive diagnosis and management plan, respectively. A conventionally managed historical control group (three-month pre-EASE period in 2003) was compared with the EASE group (2004 to 2006). The conventional referral mechanism continued concurrently with EASE. RESULTS: A comparison between pre-EASE (n=311) and EASE (n=3096) revealed no difference in the mean (± SD) age (60±16 years), sex (55% and 52% men, respectively) or reason for referral, including chest pain (31% and 40%, respectively) and arrhythmia (27% and 29%, respectively). Cardiac EASE reduced the time to initial cardiac consultation (from 71±45 days to 33±19 days) and time to a definitive diagnosis (from 120±86 days to 51±58 days) (P<0.0001). The annual number of new referrals increased from 1512 in 2002 to 2574 in 2006 due to growth in the Cardiac EASE clinic. The number of patients seen through the conventional referral mechanism and their wait times remained constant during the study period. CONCLUSIONS: Cardiac EASE reduced

    Correction of dental crowding can be achieved with several orthodontic procedures like extraction of teeth, proximal stripping etc. In contemporary orthodontic practice, resolution of incisor crowding is most commonly achieved by the use of canine lacebacks. This method takes time, requires frequent activations and taxes anchorage since it involves the "PULL" mechanics. In order to overcome these disadvantages, mostly the time factor, we devised a method of using open coil NiTi spring on 0.016" SS wire piggy backed on the 0.014" heat activated NiTi base arch wire ligated only at the canines. This method, resolved the incisor crowding in almost one third of the time taken with the use of canine lacebacks. Moreover, the result was more physiologic since light continuous force was applied with the spring and it essentially eliminated the anchorage loss since it involved "PUSH" mechanics.

    The use of orthodontic treatment in adult patients is becoming more common and these patients have more specific objectives and concerns related to facial and dental aesthetics, specially regarding duration of treatment. Dentists are on the lookout for techniques for increased efficiency in orthodontic treatment. Alveolar Corticotomy-assisted orthodontic treatment is a recent orthodontic technique that is recently gaining wide acceptance and is recorded as effective means of accelerating orthodontic treatment. A 17-year-old female patient was undergoing orthodontic treatment for the past one year but during her space closure, a visual examination confirmed a buccal thickening that was encountered in the buccal plate between premolars and canine. Periodontal intervention involved elective alveolar decortication in the form of dots performed around the teeth that were to be moved. This was carried out to induce a state of increased tissue turnover and a transient osteopenia, which further helps in faster rate of orthodontic tooth movement. Its main advantages are reduction of treatment time and post-orthodontic stability. PMID:26894189

    As a nuclear emergency response system, numerical models to predict the atmospheric dispersion of radionuclides have been developed at Japan Atomic Energy Agency (JAEA). Evolving these models by incorporating new schemes for physical processes and up-to-date computational technologies, a numerical simulation system, which consists of dynamical models and material transport models for the atmospheric, terrestrial, and oceanic environments, has been constructed to apply for various environmental studies. In this system, the combination of a non-hydrostatic atmospheric dynamic model and Lagrangian particle dispersion model is used for the emergency response system. The utilization of detailed meteorological field by the atmospheric model improves the model performance for diffusion and deposition calculations. It also calculates a large area domain with coarse resolution and local area domain with high resolution simultaneously. The performance of new model system was evaluated using measurements of surface deposition of 137 Cs over Europe during the Chernobyl accident. (author)

    We study the motion of a classical point body of mass M, moving under the action of a constant force of intensity E and immersed in a Vlasov fluid of free particles, interacting with the body via a bounded short range potential Psi. We prove that if its initial velocity is large enough then the body escapes to infinity increasing its speed without any bound "runaway effect". Moreover, the body asymptotically reaches a uniformly accelerated motion with acceleration E/M. We then discuss at a he...

    Previous neuropsychiatric studies suggest a relationship between reading disability and cognitive impulsivity. This relationship is not entirely explained by the high comorbidity between reading disability and attention deficit hyperactivity disorder (ADHD), as children with a co-occurrence of these disorders tend to be more impulsive than those with ADHD only. Other research has demonstrated that poor verbal skill (irrespective of the presence of dyslexia) deficits in executive functions and impulsivity are important risk factors for criminal behaviour. The present study bridges these two research traditions by examining whether patients undergoing forensic psychiatric investigation who also have dyslexia, have a cognitive style characterized by impulsivity. Male forensic patients (mean age 27 years, range 16-35) with (n = 9) and without (n = 13) dyslexia were evaluated on the computerized EuroCog test battery. The findings suggest that patients with dyslexia tend to use a cognitive impulsive style and suggest a more direct link between dyslexia and cognitive impulsivity that is not mediated by the presence of ADHD. In order to identify treatment needs and tailor treatment accordingly, forensic patients should be assessed with respect to poor verbal skill, dyslexia and impulsivity.

    Dominique Jean Larrey (1766-1842) has been described as the father of modern military surgery and is considered even today as the model military surgeon. He developed a plan of rapid evacuation of wounded soldiers from the battlefield during combat, using flexible medical units which he named ambulances volantes ("flying ambulances"). He won the admiration of Napoleon Bonaparte (1769-1821), who was amazed by the results of Larrey's sanitary system. Larrey spent almost 18 years with Napoleon, accompanying him in 25 campaigns, 60 battles, and more than 400 engagements. Napoleon's enormous military success was due not only to his strategy and skill but also to the medical services provided by Larrey. The surgeon became a master of wound management and limb amputation. In his vivid battlefield journals, Larrey documented the course of tetanus, the pathophysiology of cold injury, the effective control of hemorrhage, the drainage of empyema and hemothorax, the aspiration of pericardial effusion or hemopericardium, and the packing of sucking chest wounds. Larrey established a categorical rule for the triage of war casualties, treating the wounded according to the observed gravity of their injuries and the urgency for medical care, regardless of their rank or nationality.

    Pedogenesis and drainage determine quantity and quality of material to be transported from the terrestrial ecosystem to aquatic ecosystem. Thus identification of controlling factors for the accumulation of certain elemental burden is important while, studying recent anthropogenic sources on soil and ground water elemental geochemistry. The continuous supply of organic and inorganic material in aquatic system such as lake, rivers and estuaries renders the sediment-water interface by marked chemical changes, resulting in steep gradients in physical, chemical and biological properties. Biogenic, authigenic and mineral particle which settle at the sediment surface accumulate to relatively high concentration and compared to their time in water column, have an appreciably long time in which to react mutually henceforth to the surrounding interacting forces. The particle flux in the ocean response to wind speed, aerosol deposition, nutrient level, carbon dioxide levels in the mixed layer, availability of the trace element such as Fe and volcanic emissions. Biochemical processes taking place in the deep ocean are coupled to the atmospheric processes via the particle flux in the ocean. As the oceanic flux, responds to the climatic and environmental forces, it has also a potential to detect and monitor, thus permitting the reconstruction of the global changes in the past. Thus, in spite of the fact that are distinct correlation between concentration and the distance of the sampling point from potential source such as industry, highway or municipal can not be established sediments from sea, lake, estuaries or river could be valuable tool to show spatial and temporal trends of metal contamination. Studies have been undertaken to construct a comprehensive scenario of environmental impact from marine pollution. Hence present work attempts to evaluate enrichment of various metals and cations in marine sediments from Japanese and Pakistan coastal areas. Concentration of Cr, Cu, Cd, Mn, Fe, Pb, Sr, Na, Ca, Ba, K, Al, Zn, Y and Ni were measured by AES and AAS in all sediment samples and normalised grain size and identical analytical conditions were maintained so that the variation in mineralogical effects as distinct from anthropogenic effect, could be differentiated.

    Full Text Available In a digital world, it seems as if the boundaries between rich and poor are becoming increasingly blurred. A mobinomic world is created through the use of cellular telephones, which plays an important role on multiple levels of socioeconomic understanding. Various advantages are created through the interplay between the power of mobility and the convergence of various forms of media. Considering the immediate accessibility of an overflow of data in various forms as well as time pressure, decision-making is increasingly becoming associated with living in the fast lane of the digital world. Unfortunately, the cost of faster decision-making is that it could potentially result in individuals making poor decisions on various levels. A practical-theological exploration, as embedded in a transversal rational engagement, entails a preliminary investigation and description of this digital reality, especially as portrayed in the dynamics of decision-making associated with the social media platform Twitter.

    Using a sample of English school children, we use accelerometery and global positioning systems to identify whether different intensities of activity (light, moderate, and vigorous) occur in different environments, and whether environments for bouts of moderate to vigorous activity (MVPA) vary from those for non-bout MVPA. We find that land uses such as buildings and roads and pavements were generally used for light activity, whilst green environments such as gardens, parks, grassland and farmland appear supportive of vigorous activity. Built land uses such as hard surface play areas were particularly used for activity of short duration. Future work may consider differentiating light activity from moderate and vigorous, and separating bout and non-bout MVPA to better identify environmental supportiveness for activity in children.

    Poor diet in childhood increases risk of obesity but the relationship between access to food and children's food choice is underexplored. We determined relationships between distance to and density of food outlets on children's food choice. Children (n 1721) aged 9-10 years who participated in a cross-sectional study from a sample of state and private schools across urban and rural areas. Food consumption was reported using a short validated FFQ. A Geographic Information System was used to determine proximity to local food outlets. Multivariable regression analyses were performed to determine associations between food consumption and distance to and density of local food outlets. Norfolk, England. Boys (n 754) and girls (n 967) aged 9-10 years. The impact of distance to or density of food outlets on food choice was small after adjustment. Living further away from a supermarket increased portions of fruit (0.11 portions/week per 1 km increase in distance to nearest supermarket, P < 0.05) and vegetables (0.11 portions/week, P < 0.05) consumed. Living closer to convenience stores was also associated with an increased consumption of crisps, chocolate and white bread. Density of supermarkets was associated with both an increase in vegetable intake (0.31 portions/week, P < 0.05) and unhealthy foods. Distance to and density of food outlets are both associated with children's food choice, although the impact appears to be small and the relationship is complex. However, the effects of individual foods combined could be important, particularly as even small differences in intake can impact on body weight over time.

    We report 2 cases of rat-bite fever (RBF), a multisystem zoonosis, in children and review the literature. RBF is caused by I of 2 Gram-negative organisms: Streptobacillus moniliformis or, less commonly, Spirillum minus. Both of our cases developed in school-aged girls with a history of rat exposure who presented with a multisystem illness consisting of fever, petechial and purpuric rash, arthralgia and polyarthritis. Both responded promptly to antibiotic treatment. An additional 10 cases from a MEDLINE review (1960-2000) are reviewed. RBF must be included in the differential diagnosis of febrile patients with rashes and a history of exposure to rats.

    Rat bite fever (RBF), a systemic infection of Streptobacillus moniliformis or Spirillum minus characterized by fever, arthralgias and petechial-purpuric rash on the extremities, carries a mortality rate of 7% to 10% if untreated. In Canada, one adult and two paediatric cases of RBF have been reported since 2000. In recent years, pet rats have become quite popular among children, placing them at an increased risk for RBF. Thus, paediatricians need to be more wary of the potential for RBF in their patients. In the present report, a culture-confirmed case of RBF and two additional cases of suspected infection are described. PMID:21358889

    2003-09-01

    Rat bite fever is a rarely reported acute febrile bacterial illness caused by Streptobacillus moniliformis or Spirillum minus following a rat bite. It is classically characterised by abrupt onset of fever with rigors, myalgias, headache, and the appearance of a generalised maculopapular petechial skin rash. Polyarthritis complicates the course of the disease in up to 50% of infected patients, and numerous hurdles can make the diagnosis particularly difficult in the absence of fever or rash, as in the present case. A high degree of awareness is necessary to make the correct diagnosis in such cases. Diagnosis has important prognostic implications as the disease is potentially lethal, but easily treatable.

    The peptidoglycan cell wall of bacteria is responsible for maintaining the cell shape and integrity. During the bacterial life cycle, the growth of the cell wall is affected by mechanical stress and osmotic pressure internal to the cell. We develop a theory to describe cell shape changes under the influence of mechanical forces. We find that the theory predicts a steady state size and shape for bacterial cells ranging from cocci to spirillum. Moreover, the theory suggest a mechanism by which bacterial cytoskeletal proteins such as MreB and crescentin can maintain the shape of the cell.

    The first demonstration that samples of lignite at a depth of 10 m are considerably enriched in bacteria is reported. According to direct microscopy, the abundance of bacteria was about 10{sup 7} cells/g. About 70% of cells had intact cell membranes and small size, which points to their anabiotic state. The fungal mycelium length was no more than 1 m. Lignite inoculation onto solid glucose-yeast-peptone medium allowed us to isolate bacteria of the genera Bacillus, Rhodococcus, Arthrobacter, Micrococcus, Spirillum, and Cytophaga. Representatives of the genera Penicillium and Trichoderma were identified on Czapek medium. Moistening of lignite powder increased the microbial respiration rate and microbial and fungal abundance but did not increase their generic diversity. This finding suggests that the studied microorganisms are autochthonous to lignite.

  4. Constant Flux of Spatial Niche Partitioning through High-Resolution Sampling of Magnetotactic Bacteria.

    2017-10-15

    Magnetotactic bacteria (MTB) swim along magnetic field lines in water. They are found in aquatic habitats throughout the world, yet knowledge of their spatial and temporal distribution remains limited. To help remedy this, we took MTB-bearing sediment from a natural pond, mixed the thoroughly homogenized sediment into two replicate aquaria, and then counted three dominant MTB morphotypes (coccus, spirillum, and rod-shaped MTB cells) at a high spatiotemporal sampling resolution: 36 discrete points in replicate aquaria were sampled every ∼30 days over 198 days. Population centers of the MTB coccus and MTB spirillum morphotypes moved in continual flux, yet they consistently inhabited separate locations, displaying significant anticorrelation. Rod-shaped MTB were initially concentrated toward the northern end of the aquaria, but at the end of the experiment, they were most densely populated toward the south. The finding that the total number of MTB cells increased over time during the experiment argues that population reorganization arose from relative changes in cell division and death and not from migration. The maximum net growth rates were 10, 3, and 1 doublings day -1 and average net growth rates were 0.24, 0.11, and 0.02 doublings day -1 for MTB cocci, MTB spirilla, and rod-shaped MTB, respectively; minimum growth rates for all three morphotypes were -0.03 doublings day -1 Our results suggest that MTB cocci and MTB spirilla occupy distinctly different niches: their horizontal positioning in sediment is anticorrelated and under constant flux. IMPORTANCE Little is known about the horizontal distribution of magnetotactic bacteria in sediment or how the distribution changes over time. We therefore measured three dominant magnetotactic bacterium morphotypes at 36 places in two replicate aquaria each month for 7 months. We found that the spatial positioning of population centers changed over time and that the two most abundant morphotypes (MTB cocci and MTB spirilla

  5. The impact of freeze-thawing on the friability of formed elemental sulfur

    Energy Technology Data Exchange (ETDEWEB)

    Clark, P.D.; Almond, P.

    1995-10-01

    Winter weather fluctuation tests were performed in a laboratory to determine the freeze-thaw effect on the particle size distribution and friability of sulfur samples of Polish Air Prills, Procor GX Granules, Petrosul, Sandvik Rotoform, and slate. Formed elemental sulfur is often stored outdoors and is subjected to temperature fluctuations which could potentially result in structural stress, particularly if the sulfur contained any moisture from rainwater or melting snow. Concern was expressed that sulfur stored under these conditions might have increased friability during shipping and handling. Results of stress level tests indicated that winter weather fluctuations did not effect the particle size distribution or friability of the samples. When sulfur samples were in contact with water for one month, there were was no significant change in overall friability. It was concluded that all premium product forms of solid elemental sulfur could be stored outdoors, even if subjected to freeze-thaw cycles. 4 tabs., 5 figs.

  6. Nuclear power as a necessary option, albeit in insufficient one

    International Nuclear Information System (INIS)

    Altin, V.

    2007-01-01

    In this presentation a comparative assessment of known energy resources are made with respect to their energy densities. Fossil fuels have formed the foundation of a worldwide economic development realized throughout the 20th century. Their comparatively high energy densities have made faster energy flows and thereby higher power levels and speedy development possible. However, renewable sources that are already feasible have much lower levels of energy densities. Their large scale utilization in lieu of fossil fuels would necessitate either reduction of economic growth rates to 'sustainable' levels or speedy development of feasible large scale storage technologies. Nuclear energy appears to impose itself as a necessity to alleviate this transition period, albeit within the constraint of known uranium reserves an insufficient one

    We present GalMC (Acquaviva et al. 2011), our publicly available Markov Chain Monte Carlo algorithm for SED fitting, show the results obtained for a stacked sample of Lyman Alpha Emitting galaxies at z ~ 3, and discuss the dependence of the inferred SED parameters on the assumptions made in modeling the stellar populations. We also introduce SpeedyMC, a version of GalMC based on interpolation of pre-computed template libraries. While the flexibility and number of SED fitting parameters is reduced with respect to GalMC, the average running time decreases by a factor of 20,000, enabling SED fitting of each galaxy in about one second on a 2.2GHz MacBook Pro laptop, and making SpeedyMC the ideal instrument to analyze data from large photometric galaxy surveys.

    Sterilization of fluids by means of microfiltration is commonly applied in research laboratories as well as in pharmaceutical and industrial processes. Sterile micropore filters are subject to microbiological validation, where Brevundimonas diminuta is used as a standard test organism. However, several recent reports on the ubiquitous presence of filterable bacteria in aquatic environments have cast doubt on the accuracy and validity of the standard filter-testing method. Six different bacterial species of various sizes and shapes (Hylemonella gracilis, Escherichia coli, Sphingopyxis alaskensis, Vibrio cholerae, Legionella pneumophila, and B. diminuta) were tested for their filterability through sterile micropore filters. In all cases, the slender spirillum-shaped Hylemonella gracilis cells showed a superior ability to pass through sterile membrane filters. Our results provide solid evidence that the overall shape (including flexibility), instead of biovolume, is the determining factor for the filterability of bacteria, whereas cultivation conditions also play a crucial role. Furthermore, the filtration volume has a more important effect on the passage percentage in comparison with other technical variables tested (including flux and filter material). Based on our findings, we recommend a re-evaluation of the grading system for sterile filters, and suggest that the species Hylemonella should be considered as an alternative filter-testing organism for the quality assessment of micropore filters.

    Telomeres integrity is indispensable for chromosomal stability by preventing chromosome erosion and end-to-end fusions. During meiosis, telomeres attach to the inner nuclear envelope and cluster into a highly crowded microenvironment at the bouquet stage, which requires specific mechanisms to protect the telomeres from fusion. Here, we demonstrate that germ cell-specific knockout of a shelterin complex subunit, Trf1, results in arrest of spermatocytes at two different stages. The obliterated telomere-nuclear envelope attachment in Trf1-deficient spermatocytes impairs homologue synapsis and recombination, resulting in a pachytene-like arrest, while the meiotic division arrest might stem from chromosome end-to-end fusion due to the failure of recruiting meiosis specific telomere associated proteins. Further investigations uncovered that TRF1 could directly interact with Speedy A, and Speedy A might work as a scaffold protein to further recruit Cdk2, thus protecting telomeres from fusion at this stage. Together, our results reveal a novel mechanism of TRF1, Speedy A, and Cdk2 in protecting telomere from fusion in a highly crowded microenvironment during meiosis.

  14. Application of Acoustic and Optic Methods for Estimating Suspended-Solids Concentrations in the St. Lucie River Estuary, Florida

    Science.gov (United States)

    Patino, Eduardo; Byrne, Michael J.

    2004-01-01

    Acoustic and optic methods were applied to estimate suspended-solids concentrations in the St. Lucie River Estuary, southeastern Florida. Acoustic Doppler velocity meters were installed at the North Fork, Speedy Point, and Steele Point sites within the estuary. These sites provide varying flow, salinity, water-quality, and channel cross-sectional characteristics. The monitoring site at Steele Point was not used in the analyses because repeated instrument relocations (due to bridge construction) prevented a sufficient number of samples from being collected at the various locations. Acoustic and optic instruments were installed to collect water velocity, acoustic backscatter strength (ABS), and turbidity data that were used to assess the feasibility of estimating suspended-solids concentrations in the estuary. Other data collected at the monitoring sites include tidal stage, salinity, temperature, and periodic discharge measurements. Regression analyses were used to determine the relations of suspended-solids concentration to ABS and suspended-solids concentration to turbidity at the North Fork and Speedy Point sites. For samples used in regression analyses, measured suspended-solids concentrations at the North Fork and Speedy Point sites ranged from 3 to 37 milligrams per liter, and organic content ranged from 50 to 83 percent. Corresponding salinity for these samples ranged from 0.12 to 22.7 parts per thousand, and corresponding temperature ranged from 19.4 to 31.8 ?C. Relations determined using this technique are site specific and only describe suspended-solids concentrations at locations where data were collected. The suspended-solids concentration to ABS relation resulted in correlation coefficients of 0.78 and 0.63 at the North Fork and Speedy Point sites, respectively. The suspended-solids concentration to turbidity relation resulted in correlation coefficients of 0.73 and 0.89 at the North Fork and Speedy Point sites, respectively. The adequacy of the

    This paper presents the results of an experimental study of the biosynthesis of magnetite nanoparticles (BMNPs) with particle sizes between 10 nm and 60 nm. The biocompatible magnetic nanoparticles are produced from Magnetospirillum magneticum (M.M.) bacteria that respond to magnetic fields. M.M. bacteria were cultured and used to synthesize magnetite nanoparticles. This was done in an enriched magnetic spirillum growth medium (EMSGM) at different pH levels. The nanoparticle concentrations were characterized with UV–Visible (UV–Vis) spectroscopy, while the particle shapes were elucidated via transmission electron microscopy (TEM). The structure of the particles was studied using X-ray diffraction (XRD), while the hydrodynamic radii, particle size distributions and polydispersity of the nanoparticles were characterized using dynamic light scattering (DLS). Carbodiimide reduction was also used to functionalize the BMNPs with a molecular recognition unit (luteinizing hormone releasing hormone, LHRH) that attaches specifically to receptors that are over-expressed on the surfaces of most breast cancer cell types. The resulting nanoparticles were examined using Fourier Transform Infrared (FTIR) spectroscopy and quantitative image analysis. The implications of the results are then discussed for the potential development of magnetic nanoparticles for the specific targeting and treatment of breast cancer. - Highlights: • Biosynthesis of MNPs with clinically relevant sizes between 10 and 60 nm. • New insights into the effects of pH and processing time on nanoparticle shapes and sizes. • Successful conjugation of biosynthesized magnetite nanoparticles to LHRH ligands. • Conjugated BMNPs that are monodispersed with potential biomedical relevance. • Magnetic properties of biosynthesized MNPs suggest potential for MRI enhancement.

    A new microaerophilic, Gram-negative, motile, 2-3 microm long and 0.3 microm wide, vibrioid to spirillum-shaped, CO oxidizing bacterium, designated strain MV, isolated from marine sediment (The North Sea) is described. Strain MV was able to couple the oxidation of CO to the reduction of elemental sulphur, DMSO and thiosulphate. Growth occurred with up to 100% (v/v) CO in the headspace. Acetate was needed as carbon source. No growth on CO was observed with nitrate and selenate as electron acceptor. Sulphite, elemental sulphur, DMSO, thiosulphate, nitrate, nitrite, perchloroethylene, arsenate and selenate were used as electron acceptors with pyruvate as energy and carbon source. Microaerophilic growth was observed. In non-agitated cultures growth occurred at atmospheric oxygen concentrations in the headspace. Hydrogen (with acetate as carbon source), formate (with acetate as carbon source), pyruvate, lactate, succinate, fumarate, malate alpha-ketoglutaric acid, aspartate and yeast extract (1% (w/v)) supported growth with nitrate as electron acceptor. Fumarate and malate were fermented. Vitamins were not required for growth. The strain was cytochrome C oxidase and catalase positive. The DNA mol G+C content was 30.5%. 16S rRNA gene sequence comparison showed that strain MV grouped within the genus Sulfurospirillum with Sulfurospirillum arcachonense (sequence similarity 98.3%) as closest relative. The relative DNA-DNA relatedness between strain MV and S. arcachonense was 33.1%. Based on a detailed phenotypic and phylogenetic analysis, inclusion of strain MV in the genus Sulfurospirillum as a well separated new species is proposed. As species name we propose Sulfurospirillum carboxydovorans. The type strain is strain MV (ATCC BAA-937 = DSM 16295, GenBank accession number: AY740528).

    Gadolinium-enhanced MR angiography (GEMRA) of the thoracoabdominal aorta is a noninvasive technique that can rapidly delineate the branch vessels diseases, without flow or respiration artifacts, obtained with non contrast MRA. The objective of this paper is to show the main clinical applications of GEMRA, compared to non contrast sequences. We have evaluated 30 patients with thorocoabdominal aorta diseases. These patients have been examined with GEMRA (3D, FFE sequences) obtained after 30 mlIV contrast injection and non contrast MRA (2D-TOF sequences). In our experience, gadolinium-enhanced MRA is a high resolution and speedy technique with advantages over non contrast MRA. (author)

    Liquids can now be heated at low temperature directly at the point of end use, thanks to flexible and customized natural gas technologies. For customers these advances eliminate the need for poorly-performing central boilers, while investors can look forward to a reduction in the period of time needed to recover investments. Decentralization of the production offers many challenges to industries that have to produce vast quantities of hot water, among them increased efficiency, direct and speedy response to demands for energy, and reduced maintenance expenses. Consumers can also look forward to reduced need for energy, hence better control of the energy dollar. 2 figs

    In nuclear power plants, it is very important to foresee occurring events with in-operation -inspection (IOI) since the foreseeing makes plant maintenance more speedy and reliable. Moreover, information on plant condition under operating would make period of in-service inspection (ISI) shorter because maintenance plan can be made effectively using the information. In this study, a high cycle fatigue diagnostic system is being developed applying to especially pipe branches with small diameter under in-operating condition, which are in the radioactive areas of PWR plants and hard to access. This paper presents a concept of the in-operating diagnostic system and current status of developing sensing systems. (author)

    Byrne, Michael J.; Patino, Eduardo

    2004-01-01

    A hydrologic analysis was made at three canal sites and four tidal sites along the St. Lucie River Estuary in southeastern Florida from 1998 to 2001. The data included for analysis are stage, 15-minute flow, salinity, water temperature, turbidity, and suspended-solids concentration. During the period of record, the estuary experienced a drought, major storm events, and high-water discharge from Lake Okeechobee. Flow mainly occurred through the South Fork of the St. Lucie River; however, when flow increased through control structures along the C-23 and C-24 Canals, the North Fork was a larger than usual contributor of total freshwater inflow to the estuary. At one tidal site (Steele Point), the majority of flow was southward toward the St. Lucie Inlet; at a second tidal site (Indian River Bridge), the majority of flow was northward into the Indian River Lagoon. Large-volume stormwater discharge events greatly affected the St. Lucie River Estuary. Increased discharge typically was accompanied by salinity decreases that resulted in water becoming and remaining fresh throughout the estuary until the discharge events ended. Salinity in the estuary usually returned to prestorm levels within a few days after the events. Turbidity decreased and salinity began to increase almost immediately when the gates at the control structures closed. Salinity ranged from less than 1 to greater than 35 parts per thousand during the period of record (1998-2001), and typically varied by several parts per thousand during a tidal cycle. Suspended-solids concentrations were observed at one canal site (S-80) and two tidal sites (Speedy Point and Steele Point) during a discharge event in April and May 2000. Results suggest that most deposition of suspended-solids concentration occurs between S-80 and Speedy Point. The turbidity data collected also support this interpretation. The ratio of inorganic to organic suspended-solids concentration observed at S-80, Speedy Point, and Steele Point

    1989-01-01

    According to the national research program revised by the Japan Nuclear Safety Commission after the TMI-2 reactor accident JAERI started the development of a computer code system for the real-time prediction of environmental consequences following a nuclear reactor accident, and in 1985 the basic development of the System for Prediction of Environmental Emergency Dose Information SPEEDI was completed. The system consists of three-dimensional models of wind field calculation (WIND04), dispersion calculation (PRWDA) and internal and external dose calculation (CIDE), and is designed to speedily predict radioactive concentration in the air, the ground deposition and radiation doses of upto 100 km range by simulation calculation when the radioactive materials are accidentally released from a reactor. At Chernobyl accident the calculational domain of SPEEDI were extended tentatively upto 2000 km, and simulation calculations of the movement of radioactive cloud were executed, and the estimation of the amounts of released radioactivities were made using calculated results and observed data. The calculated distribution and the movement of plume well agreed with the distribution patterns evaluated from observation data, and the estimated source term agreed approximately with data reported from USSR and other countries.

    In cases when an accident happens to arise with some risk for emission of a large amount radioactivity from the nuclear facilities, the environmental emergency due to this accident should be predicted rapidly and be informed immediately. The SPEEDI network system for such purpose was completed and now operated by Nuclear Safety Technology Center (NUSTEC) commissioned to do by Ministry of Education, Culture, Sports, Science and Technology, Japan. Fujitsu has been contributing to this project by developing the principal parts of the network performance, by introducing necessary servers, and also by keeping the network in good condition, such as with construction of the system followed by continuous operation and maintenance of the system. Real-time prediction of atmospheric diffusion of radionuclides for nuclear accidents in the world is now available with experimental verification for the real-time emergency response system. Improvement of worldwide version of the SPEEDI network system, accidental discharge of radionuclides with the function of simultaneous prediction for multiple domains and its evaluation is possible.

    1984-11-01

    High-activity tritiated waste generated in the United States is mainly composed of tritium gas and tritium-contaminated organic solvents sorbed onto Speedi-Dri which are packaged in small glass bulbs. Low-activity waste consists of solidified and adsorbed liquids. In this report, current packages for high-activity gaseous and low-activity adsorbed liquid wastes are emphasized with regard to containment potential. Containers for low-level radioactive waste containing large amounts of tritium need to be developed. An integrity may be threatened by: physical degradation due to soil corrosion, gas pressure build-up (due to radiolysis and/or biodegradation), rapid permeation of tritium through the container, and corrosion from container contents. Literature available on these points is summarized in this report. 136 references, 20 figures, 40 tables

    Point kernel integration (PKI) method is widely used in the visualization of radiation field in engineering applications because of the features of quickly dealing with large-scale complicated geometry space problems. But the traditional PKI programs have a lot of restrictions, such as complicated modeling, complicated source setting, 3D fine mesh results statistics and large-scale computing efficiency. To break the traditional restrictions for visualization of radiation field, ARShield was developed successfully. The results show that ARShield can deal with complicated plant radiation shielding problems for visualization of radiation field. Compared with SuperMC and QAD, it can be seen that the program is reliable and efficient. Also, ARShield can meet the demands of calculation speediness and interactive operations of modeling and displaying 3D geometries on a graphical user interface, avoiding error modeling in calculation and visualization.

    Transient Sodium Boiling Tests and Fuel Failure Propagation Tests are being conducted with the out-of-pile test facility, SIENA, in the Core Safety Section of O-arai Engineering Center. The experimental data are recorded using a digital data acquisition system controlled by a HP-1000E computer. The SICILIAN (Speedy Illustration Code for Inspection Line Anomaly) code was developed to obtain quick graphic outputs of data recorded in the magnetic tapes. The program is written in BASIC and Assembler languages and uses a data processing system composed of a desktop computer HP 9845B, a magnetic tape system, a magnetic disc and an eightcolor plotter. The SICILIAN code enables us to get graphic outputs soon after a run. These outputs are very helpful to inspect anomaly in the instrument circuit and to check the experimental conditions of coming runs. (author)

    The nuclear controversy has recently taken a dynamic turn full of tensions. This is particularly true of the FRG where, after many years of continuous speedy development and the erection of the first large commercial power stations, a tough resistance movement of citizens' initiatives, expecially a radical opposition of some groups, has been growing over the past six months. Since the peaceful uses of nuclear energy were first embarked upon in the Federal Republic in the mid-fifties also the economic situation and the wishes and objectives of the working population have undergone major changes. While, in the sixties, most people sought high grade, qualitatively demanding jobs, a wish which was catered to very much by the fundamentally new technology of the utilization of nuclear energy, the two major goals of the working population, i.e., job security and job quality, have meanwhile changed positions on the scale of values.

    In the paper, it is suggested that the hazard to the population which would result from vessel failure rate of the order of 10 -6 to 10 -7 per vessel year could be acceptable to society on the basis of other natural and man-made risks. The paper considers the problems of demonstrating safety by calculation based on fracture mechanics, and indicates some of the uncertainties, and inconsistencies in the theory, particularly the effect of cracks in locally degraded volumes of material. The phenomenon of crack arrest is considered, and attention is drawn to the uncertainties as indicated at least by some tests. There is need for speedy resolution of this problem. The uncertainties in material properties, heat treatment and residual stresses are considered, and a proposed upper limit for residual defects ('original sin') is proposed. (orig.) [de

    The energy industry in Eastern Europe is preparing for the free market economy. The ambitions goal is to get fit and prepared for joining the free market economy as a competitor, and within the shortest possible time at that, struggling against the sharp wind of change that will blow, and trying to make the best of actually very unfavourable economic and political conditions. Priority has been given to privatisation of power plants and electricity networks, and to a speedy connection to the Western grids. However, all parties concerned are well aware that this task cannot be accomplished out of Russia's own resources alone. Whether the economy in Russia can be put on a stable footing and develop stable structures will depend on the development and efficient use of nuclear power, as the most important resources of Russia's energy industry are concentrated in the eastern part of the country, while 70% of electricity generation and demand is concentrated in the European part.

    Recently, secure quantum key distribution based on Deutsch's algorithm using the Bell state is reported (Nagata and Nakamura, Int. J. Theor. Phys. doi: 10.1007/s10773-017-3352-4, 2017). Our aim is of extending the result to a multipartite system. In this paper, we propose a highly speedy key distribution protocol. We present sequre quantum key distribution based on a special Deutsch-Jozsa algorithm using Greenberger-Horne-Zeilinger states. Bob has promised to use a function f which is of one of two kinds; either the value of f( x) is constant for all values of x, or else the value of f( x) is balanced, that is, equal to 1 for exactly half of the possible x, and 0 for the other half. Here, we introduce an additional condition to the function when it is balanced. Our quantum key distribution overcomes a classical counterpart by a factor O(2 N ).

    This book provides a uniform framework describing how fuzzy rough granular neural network technologies can be formulated and used in building efficient pattern recognition and mining models. It also discusses the formation of granules in the notion of both fuzzy and rough sets. Judicious integration in forming fuzzy-rough information granules based on lower approximate regions enables the network to determine the exactness in class shape as well as to handle the uncertainties arising from overlapping regions, resulting in efficient and speedy learning with enhanced performance. Layered network and self-organizing analysis maps, which have a strong potential in big data, are considered as basic modules,. The book is structured according to the major phases of a pattern recognition system (e.g., classification, clustering, and feature selection) with a balanced mixture of theory, algorithm, and application.

    Neutron activation analysis was used in determining the composition of used pigments, their age and origin. Microsamples from paintings with a weight of less than 10 -7 kg were taken with a hollow needle, irradiated in quartz ampoules for 20 hours in a reactor with a density of thermal neutrons of 10 13 cm -2 .s -1 and then in different configurations measured with a Ge(Li) detector. From the amount of obtained data (various paintings, different colours) a data bank will be established enabling speedy comparative evaluations. As an example the problem of the excellent white in Rubens' paintings is dealt with and the dating is discussed of the early beginnings of the use of zinc white in Guardi's paintings. (M.D.)

    Full Text Available East Asian economies have achieved spectacular growth rates in a relatively short timespan outstripping the rest of the developing world. Hence the concern of both scholarly and policymaking circles for their peculiar development strategies. Both their spectacular rise and provisional decline after the Asian financial crisis (AFC were explained from three major perspectives: statism, neoliberalism, and neoconfucianism.The paper purports to quantify and interpret the pre-crisis total factor productivity (TFP of three Northeast Asian economies by using the Solow Model. The interdependencies between their TFP dynamics were investigated via a VAR Model. The findings suggest that labour contribution has decreased over time in favour of capital inputs and/or TFP as speedy industrialisation, and a gradual refinement of international specialisation proceeded. However low or even negative TFP during the 1990s signal the emergence of structural problems that decelerate growth, and increase these economies’ vulnerability to exogenous shocks.

  14. Internal and External Dialogue: A Method for Quality Court Management

    2008-10-01

    Full Text Available The aim of quality court work is to maintain or improve public trust in the court as a vital part of a democratic society. Public confidence in the judicial system is affected by a number of factors, including speedy and judicially correct decisions which are generally understandable and a good treatment of parties and witnesses before and during court proceedings. In order to uphold and enhance public trust, courts need to work systematically to improve the quality of court functioning. But questions remain regarding how to institute quality court management, and how to achieve positive results. Although court managers in Sweden have shown an interest in starting systematic quality work, they have found it difficult to find a method for such work and systematically achieving results.

    Full Text Available The concept of beauty has acquired new dimensions due to the increasing awareness in general public about the aesthetic procedures. The problems between the patient and the cosmetologists arise when the patients expectations become very high and unrealistic. The classical concept of doctor – patient relationship born in the golden days of family physicians has undergone drastic change due to dramatic advancement in medical technology, availability of sophisticated imaging system, high tech electronics and preponderance of new diseases. However, the accountability of the doctors under the law of professional negligence has emerged as a debatable issue among the medical fraternity all over the country after the enactment of the consumer protection act, 1986, which has not only changed the law of medical negligence1, but created an inexpensive and speedy remedy against medical malpractice.

  16. INVESTIGATIONS INTO THE INFLUENCE OF GRAPHITIZATION-TIME AND -TEMPERATURE ON THE ASH CONTENT OF ELECTROGRAPHITE

    Energy Technology Data Exchange (ETDEWEB)

    Wege, E

    1963-06-15

    The de-ashing of carbon bodies at higher temperatures was found to be relatively speedy procedure. Under equal conditions, after equal time perrods, the ratio between momentary ash content and original ash content is constant, low final ash content means low original ash content. Since the ash content of the packing dust affects the graphitization system, it seemed possible to increase the de-ashing rate by the use of purex packrng dust, or to decrease the de-ashing rate by the use of impure packing dust. Since the de-ashing speed is dependent on the temperature, small differences in the effective temperature will affect the ash content considerably. Thus, in order to prevent large differences in the final product as far as the ash content is concerned, it is suggested that the most uniform furnace temperatures be ensured. (P.C.H.)

    2009-01-01

    The lifetimes of the J π =4 + , 6 + , 8 + , and 10 + levels along the ground state band in 168 Hf were measured by means of the recoil distance Doppler shift (RDDS) method using the New Yale Plunger Device (NYPD) and the SPEEDY detection array at Wright Nuclear Structure Laboratory of Yale University. Excited states in 168 Hf were populated using the 124 Sn( 48 Ti,4n) fusion evaporation reaction. The new lifetime values are sufficiently precise to clearly prove the increase of quadrupole deformation as a function of angular momentum in the deformed nucleus 168 Hf. The data agree with the predictions from the geometrical confined β-soft (CBS) rotor model that involves centrifugal stretching in a soft potential

    The provision of ambulatory care by major retailers is small but growing, providing speedy attention to consumers with minimal wait times and no appointments necessary. Users of these clinics are satisfied with the care they receive. Primary care physicians have opposed retail clinics, concerned that conditions will be misdiagnosed, opportunities to address comorbidities and risk behaviors will be missed, necessary follow-up care will be delayed or absent, and the profit motive will lead to cutting corners. Public health is now being challenged to capitalize on the advantageous possibilities these clinics can offer, such as serving uninsured patients, while remaining vigilant regarding potential hazards, such as financial pressures that could negatively affect health care quality, continuity, and accessibility.

    2013-07-01

    Detailed measurement of cell phenotype information from digital fluorescence images has the potential to greatly advance biomedicine in various disciplines such as patient diagnostics or drug screening. Yet, the complexity of cell conformations presents a major barrier preventing effective determination of cell boundaries, and introduces measurement error that propagates throughout subsequent assessment of cellular parameters and statistical analysis. State-of-the-art image segmentation techniques that require user-interaction, prolonged computation time and specialized training cannot adequately provide the support for high content platforms, which often sacrifice resolution to foster the speedy collection of massive amounts of cellular data. This work introduces a strategy that allows us to rapidly obtain accurate cell boundaries from digital fluorescent images in an automated format. Hence, this new method has broad applicability to promote biotechnology.

  3. Energy policy and nuclear power. Expectations of the power industry

    1995-01-01

    In the opinion of the power industry, using nuclear power in Germany is a responsible attitude, while opting out of nuclear power is not. Electricity utilities will build new nuclear power plants only if the structural economic and ecological advantages of nuclear power are preserved and can be exploited in Germany. The power industry will assume responsibility for new complex, capital-intensive nuclear plants only if a broad societal consensus about this policy can be reached in this country. The power industry expects that the present squandering of nuclear power resources in Germany will be stopped. The power industry is prepared to contribute to finding a speedy consensus in energy policy, which would leave open all decisions which must not be taken today, and which would not constrain the freedom of decision of coming generations. The electricity utilities remain committed proponents of nuclear power. However, what they sell to their customers is electricity, not nuclear power. (orig.) [de

    2014-01-01

    Full Text Available The method based on psychology concept has been proved to be a successful tool used for human-robot interaction. But its related research in multi-robot cooperation has remained scarce until recent studies. To solve the problem, a decision-making mechanism based on psychological values is presented to be regarded as the basis of the multi-robot cooperation. Robots give birth to psychological values based on the estimations of environment, teammates and themselves. The mapping relationship between psychological values and cooperation tendency threshold values is set up with artificial neural network. Robots can make decision on the bases of these threshold values in cooperation scenes. Experiments show that the multi-robot cooperation method presented in the paper not only can ensure the rationality of robots’ decision-making, but also can ensure the speediness of robots’ decision-making.

    Creutzfeldt-Jakob disease (CJD) and Gerstmann-Strüssler-Scheinker disease (GSSD) are transmissible spongiform encephalopathies or prion diseases affecting man. It has been reported that prion diseases may occur without the histological hallmarks of spongiform encephalopathies: vacuolation of the cerebral grey matter, neuronal loss and astrocytosis. These cases without characteristic neuropathology may go undiagnosed and consequently the true incidence of transmissible dementias is likely to have been under-estimated. Immunocytochemistry using antibodies to prion protein gives positive staining of these cases, albeit the pattern of immunostaining differs from that seen in typical forms. Accumulation of prion protein is a molecular hallmark of prion diseases, and thus a reproducible, speedy and cost-efficient immunocytochemical screening of unusual dementias may help to establish the true incidence of prion diseases.

    Mixed organic liquid waste generated from health-care and research activities containing tritium, carbon-14, and other radionuclide posed specific challenges in its management. Often, this waste becomes legacy waste in many nuclear facilities and being considered as 'problematic' waste. One of the most important recommendations made by IAEA is to perform multistage processes aiming at declassification of the waste. At this moment, approximately 3000 bottles of mixed liquid waste, with estimated volume of 6000 litres are currently stored at the National Radioactive Waste Management Centre, Malaysia and some have been stored for more than 25 years. The aim of this study is to develop a characterization protocol towards reclassification of these wastes. The characterization protocol entails waste identification, waste screening and segregation, and analytical radionuclides profiling using analytical procedures involving gross alpha beta, and gamma spectrometry. The results obtained from the characterization protocol are used to establish criteria for speedy classification of the waste. (author)

    Full Text Available The frequency of acute respiratory infections remains high in childhood. It is impossible to identify etiology most accurately in each particular case. However, according to multiple studies, viruses, their associations with each other and bacteria prevail as causative agents. In addition, it is quite often that a respiratory infection, especially in minor children, is combined with a condition of the gastrointestinal tract. Apart from symptomatic and antiviral therapies in these cases, as the authors of this article demonstrated, it is advisable to use enterosorbents. This tactics results in a decreased level of intoxication, lower intensity and duration of diarrheal syndrome, i.e. more speedy recovery.Key words: acute respiratory infections, condition of gastro tract, intoxication, diarrheal syndrome, treatment, enterosorbents, children.

    2010-04-01

    When large scale earthquake occurred, the word of "harmful rumor" came to be frequently heard. The harmful rumor means an economic damage which is caused by the action that people regard actually safe foods or areas as dangerous and then abort consumption or sightseeing. In the case of harmful rumor caused by earthquake, especially, tourism industry receives massive economic damage. Currently, harmful rumor which gives substantial economic damage have become serious social issue which must be solved. In this paper, we propose a countermeasure method for harmful rumor on the basis of media trend in order to implement speedy recovery from harmful rumor. Here, we investigate the amount and content of information which is transmitted to the general public by the media when an earthquake occurred. In addition, the media information in three earthquakes is treated as instance. Finally, we discuss an effective countermeasure method for dispeling harmful rumor through these analysis results.

    2017-01-01

    Current statistical model(CSM) has a good performance in maneuvering target tracking. However, the fixed maneuvering frequency will deteriorate the tracking results, such as a serious dynamic delay, a slowly converging speedy and a limited precision when using Kalman filter(KF) algorithm. In this study, a new current statistical model and a new Kalman filter are proposed to improve the performance of maneuvering target tracking. The new model which employs innovation dominated subjection function to adaptively adjust maneuvering frequency has a better performance in step maneuvering target tracking, while a fluctuant phenomenon appears. As far as this problem is concerned, a new adaptive fading Kalman filter is proposed as well. In the new Kalman filter, the prediction values are amended in time by setting judgment and amendment rules,so that tracking precision and fluctuant phenomenon of the new current statistical model are improved. The results of simulation indicate the effectiveness of the new algorithm and the practical guiding significance.

    Full Text Available Automatic Guided Vehicles (AGVs are navigated utilising multiple types of sensors for detecting the environment. In this investigation such sensors are replaced and/or minimized by the use of a single omnidirectional camera picture stream. An area of interest is extracted, and by using image processing the vehicle is navigated on a set path. Reconfigurability is added to the route layout by signs incorporated in the navigation process. The result is the possible manipulation of a number of AGVs, each on its own designated colour-signed path. This route is reconfigurable by the operator with no programming alteration or intervention. A low resolution camera and a Matlab® software development platform are utilised. The use of Matlab® lends itself to speedy evaluation and implementation of image processing options on the AGV, but its functioning in such an environment needs to be assessed.

    2017-01-01

    In the event of a severe nuclear or radiological accident, the release of radionuclides results in contamination of land surfaces affecting agricultural and food resources. Speedy accumulation of information and guidance on decision making is essential in enhancing the ability of stakeholders to strategize for immediate countermeasure strategies. Support tools such as decision trees and sampling protocols allow for swift response by governmental bodies and assist in proper management of the situation. While such tools exist, they focus mainly on protecting public well-being and not food safety management strategies. Consideration of the latter is necessary as it has long-term implications especially to agriculturally dependent Member States. However, it is a research gap that remains to be filled.

    2001-01-01

    Fifteen years after the Chernobyl accident, exhaustive studies by the IAEA and others provide a solid understanding of the causes and consequences of the accident, which stemmed from design deficiencies in the reactor compounded by violation of operating procedures. These deficiencies and the lack of an international notification mechanism led to the speedy adoption of early Notification and Assistance Conventions as well as later establishment of the landmark Convention on Nuclear Safety. Lessons learned from the accident were also a significant driving force behind a decade of IAEA assistance to the countries of Central and eastern Europe and the Former Soviet Union. Much of this work was focused on identifying the weaknesses in and improving the design safety of WWER and RBMK reactors

    These notes serve as an introduction to stochastic theories which are useful in population biology; they are based on a course given at the Courant Institute, New York, in the Spring of 1974. In order to make the material. accessible to a wide audience, it is assumed that the reader has only a slight acquaintance with probability theory and differential equations. The more sophisticated topics, such as the qualitative behavior of nonlinear models, are approached through a succession of simpler problems. Emphasis is placed upon intuitive interpretations, rather than upon formal proofs. In most cases, the reader is referred elsewhere for a rigorous development. On the other hand, an attempt has been made to treat simple, useful models in some detail. Thus these notes complement the existing mathematical literature, and there appears to be little duplication of existing works. The authors are indebted to Miss Jeanette Figueroa for her beautiful and speedy typing of this work. The research was supported by the Na...

    Researchers do not know if medications act the same in the spaceflight environment as they do on Earth. Aspects of the spaceflight environment (low gravity, radiation exposure, closed environment, stress) have been shown to alter human physiology. Some of these physiological changes could be expected to alter either pharmacokinetics (PK, how the body absorbs, distributes, metabolizes and excretes administered medications) or pharmacodynamics (PD, receptors or signaling systems that are the targets of medication action). Anecdotal data has suggested that, at least for certain medications or indications, inflight medication efficacy is poor. In order to prepare for exploration missions where speedy evacuation to Earth may not be a possibility, the likelihood of unexpected medication action must be determined.

  4. Del impacto mediático al olvido: la pérdida de interés noticioso como indicador de la deshumanización de los medios

    Full Text Available Present opulence news context leads media to redefine their role and functions, in order to give an answer to problems which overturn our society. Furthermore, it is a hopeful moment for Journalism and, particularly, for print press which can get the chance to recover its basic functions. Present age is determined by worldwide speedy transmission of information, but also by the ostracism of events such as conflicts, disasters or other human crisis. These are usually forgotten by journalists when first impact and novelty vanish, although it is not easy to understand the fact that these issues disappear rapidly from news titles to return later because of economic, politic or social disorder, commonly preferred by media to be related. Therefore, this article purposes a reflection on the social role of press, by analysing the interest and news coverage of the tsunami which devastated Asia-Pacific nations last December 2004 and its aftermath.

  5. An interpretation of the settlement and defences of the Otatara-Hikurangi pa complex, Hawke's Bay, New Zealand

    2005-01-01

    Despite the amorphous appearance of Hikurangi, one of New Zealand's largest pa, it is possible to draw conclusions about the defensive character of the place and its neighbour Otatara. Detailed study of vertical aerial photographs reveals potential defensive lines, which have to be interpreted in the light of the overall topography of the place. The defence of Otatara-Hikurangi relied largely on natural features, on controlling high ground, and on the speedy interior movement by defenders from one area to another as required. Fixed defences, including scarps, were a small part of the mix. Otatara-Hikurangi was an important centre in late prehistory and could probably muster large numbers of defenders.

    Full Text Available Nanotechnology is an interdisciplinary research field. In recent past efforts have been made to improve agricultural yield through exhaustive research in nanotechnology. The green revolution resulted in blind usage of pesticides and chemical fertilizers which caused loss of soil biodiversity and developed resistance against pathogens and pests as well. Nanoparticle-mediated material delivery to plants and advanced biosensors for precision farming are possible only by nanoparticles or nanochips. Nanoencapsulated conventional fertilizers, pesticides and herbicides helps in slow and sustained release of nutrients and agrochemicals resulting in precise dosage to the plants. Nanotechnology based plant viral disease detection kits are also becoming popular and are useful in speedy and early detection of viral diseases. In this article, the potential uses and benefits of nanotechnology in precision agriculture are discussed. The modern nanotechnology based tools and techniques have the potential to address the various problems of conventional agriculture and can revolutionize this sector.

    2012-01-01

    The NEAMS IPSC's are developing multidimensional, multiphysics, multiscale simulation codes based on first principles that will be capable of predicting all aspects of current and future nuclear reactor systems. These new breeds of simulation codes will include rigorous verification, validation and uncertainty quantification checks to quantify the accuracy and quality of the simulation results. The resulting NEAMS IPSC simulation codes will be an invaluable tool in designing the next generation of Nuclear Reactors and also contribute to a more speedy process in the acquisition of licenses from the NRC for new Reactor designs. Due to the high resolution of the models, the complexity of the physics and the added computational resources to quantify the accuracy/quality of the results, the NEAMS IPSC codes will require large HPC resources to carry out the production simulation runs.

    Accurate and rapid identification of bacterial pathogens of fish is essential for the effective treatment and speedy control of infections. Massive mortalities in market-sized red tilapia (Oreochromis spp.) were noticed in mariculture concrete ponds in northern Egypt. Histopathological examination revealed marked congestion in the central vein of the liver with the presence of bacterial aggregates inside the lumen and in the vicinity of the central vein. A total of 12 isolates of streptococci were obtained from the moribund fish. This study documented the ability of the MicroSeq 500 16S bacterial sequencing method to accurately identify Streptococcus agalactiae and S. dysgalactiae mixed infections from moribund red tilapia that were difficult to be recognised by the commercial biochemical systems. The continuously decreasing cost of the sequencing technique should encourage its application in routine diagnostic procedures.

    In order to take protection measures smoothly at the time of emergency in nuclear power stations and others, it is necessary to prepare information communication facilities mutually among disaster prevention organizations including the state and information transmission network for residents in surrounding areas. The matters decided in ''the measures to be taken for the time being for the countermeasures to prevent disaster in nuclear power stations and others'' are shown. In order to avoid the congestion of communication, the exclusively used communication systems are adopted for disaster prevention organizations, in which facsimile is used to transmit graphic information. The data communication circuits for distributing SPEEDI are installed between Science and Technology Agency, Nuclear Power Safety Technology Center and respective prefectures. The routes, means and order of notices must be confirmed beforehand mutually among the related organizations. As to the general communication for disaster countermeasures, the communication systems in ministries and agencies are described. (K.I.)

    2014-08-25

    Automatic Guided Vehicles (AGVs) are navigated utilising multiple types of sensors for detecting the environment. In this investigation such sensors are replaced and/or minimized by the use of a single omnidirectional camera picture stream. An area of interest is extracted, and by using image processing the vehicle is navigated on a set path. Reconfigurability is added to the route layout by signs incorporated in the navigation process. The result is the possible manipulation of a number of AGVs, each on its own designated colour-signed path. This route is reconfigurable by the operator with no programming alteration or intervention. A low resolution camera and a Matlab® software development platform are utilised. The use of Matlab® lends itself to speedy evaluation and implementation of image processing options on the AGV, but its functioning in such an environment needs to be assessed.

    The pharmaceutical packaging market is constantly advancing and has experienced annual growth of at least five percent per annum in the past few years. The market is now reckoned to be worth over $20 billion a year. As with most other packaged goods, pharmaceuticals need reliable and speedy packaging solutions that deliver a combination of product protection, quality, tamper evidence, patient comfort and security needs. Constant innovations in the pharmaceuticals themselves such as, blow fill seal (BFS) vials, anti-counterfeit measures, plasma impulse chemical vapor deposition (PICVD) coating technology, snap off ampoules, unit dose vials, two-in-one prefilled vial design, prefilled syringes and child-resistant packs have a direct impact on the packaging. The review details several of the recent pharmaceutical packaging trends that are impacting packaging industry, and offers some predictions for the future. PMID:23833515

    Late transition metal complexes that bear N-heterocyclic carbene (NHC) ligands have seen a speedy growth in their use as both, metal-based drug candidates and potentially active homogeneous catalysts in a plethora of C-C and C-N bond forming reactions. This review article focuses on the recent developments and advances in preparation and characterization of NHC-metal complexes (metal: silver, gold, copper, palladium, nickel and ruthenium) and their biomedical applications. Their design, syntheses and characterization have been reviewed and correlated to their antimicrobial and anticancer efficacies. All these initial discoveries help validate the great potential of NHC-metal derivatives as a class of effective antimicrobial and anticancer agents.

    Scientific societies provide numerous services to the scientific enterprise, including convening meetings, publishing journals, developing scientific programs, advocating for science, promoting education, providing cohesion and direction for the discipline, and more. For most scientific societies, publishing provides revenues that support these important activities. In recent decades, the proportion of papers on microbiology published in scientific society journals has declined. This is largely due to two competing pressures: authors' drive to publish in "glam journals"-those with high journal impact factors-and the availability of "mega journals," which offer speedy publication of articles regardless of their potential impact. The decline in submissions to scientific society journals and the lack of enthusiasm on the part of many scientists to publish in them should be matters of serious concern to all scientists because they impact the service that scientific societies can provide to their members and to science.

    2016-10-01

    There are contradictions among speediness, anti-disturbance performance, and steady-state accuracy caused by traditional PID controller in the existing light source systems of thermal frequency stabilizing laser with double longitudinal modes. In this paper, a new kind of fuzzy adaptive PID controller was designed by combining fuzzy PID control technology and expert system to make frequency stabilizing system obtain the optimal performance. The experiments show that the frequency stability of the designed PID controller is similar to the existing PID controller (the magnitude of frequency stability is less than 10-9 in constant temperature and 10-7 in open air). But the preheating time is shortened obviously (from 10 minutes to 5 minutes) and the anti-disturbance capability is improved significantly (the recovery time needed after strong interference is reduced from 1 minute to 10 seconds).

    The computerization of data processing in multi-disciplinary hospitals is the key factor in raising the quality of medical care provided to the population, intensifying the work of the personnel, improving the curative and diagnostic process and the use of resources. Even a small experience in complex computerization at the Botkin Hospital indicates that due to the use of the automated system the quality of data processing in being improved, a high level of patients' examination is being provided, a speedy training of young specialists is being achieved, conditions are being created for continuing education of physicians through the analysis of their own activity. At big hospitals a complex solution of administrative and curative diagnostic tasks on the basis of general hospital network of display connection and general hospital data bank is the most prospective form of computerization.

    The cases of two young men with the Gorham-Stout's syndrome of massive angiomatous osteolysis are presented. Attempted surgical removal of the pathological angiomatous tissue proved unsuccessful. Telegammatherapy with each patient receiving total focal dose of 40.0 Gy fractionated over a period of 4 weeks resulted in speedy and complete arrest of osteolysis, and in partial recalcification of the bone tissue destroyed. In one patient the favourable condition has been lasting for 9 years, in the other for 8 months from the end of the course of radiotherapy. The authors discuss the cause of a central fracture of the first patient's left acetabulum which was noted 5 years after the radiotherapy. Proceeding from their experience so far, the authors describe radiotherapy in the Gorham-Stout's syndrome as a method of choice, and give a list of the therapeutical principles. (orig.) [de

    Full Text Available An unusual penetrating chest injury was caused by high velocity road traffic accident. An 18-year-old had a four wheeler accident and was brought in emergency department with a ′bamboo′ stick on the left side chest exiting through back. After the stabilization of vital parameters, an inter-costal tube drainage was done on the left side. Except the minor brochopleural fistula which healed by 10 th day, his recovery was uneventful. The outcome was consistent with current aggressive management of penetrating chest injuries. Management of penetrating chest injury involving pulmonary trauma is based on three principles. One is stabilization of hemodynamics of patient with proper clinical evaluation. Second, a mere intercostal tube drainage sufficient for majority of the cases. Third, post-operative active as well as passive physiotherapy is necessary for speedy recovery.

    The cellular DNA is one of the components most affected by ionizing radiation. Lesions caused range from single and double stranded breaks to chemical modification of bases depending on the radiation dosage and the metabolic status of the tissue. In attempting to assess the DNA damage induced by irradiation of vegetables in a speedy and convenient manner, we examined the effect on the DNA by subjecting cauliflower to a dose of 1 kGy. If DNA is nicked by irradiation, the extent of the damage can be assessed by using DNA polymerase to repair the nicks. Comparisons were made between irradiated and non irradiated cauliflower and incorporation of 32 p deoxy GTP in the presence of the Klenow fragment of DNA polymerase measured

    The type of artificial illumination employed for chrysanthemum cultivation in greenhouses to induce photo period effect will determine its growing rate as well as the energy consumption. Incandescent filament is currently employed for artificial illumination in chrysanthemum nursery to induce photo period effect. Nowadays new illumination technology is being tested aiming energy consumption reduction. The application of illumination based on electrical discharge in sodium or mercury vapor, as well as tubular or integrated compact fluorescent bulbs in chrysanthemum cultivation is identified as the objective of this research work. The experimental part of this work was carried out in a commercial greenhouse model employing five chrysanthemum variety as Papiro, Lindy White, Mona Lisa Rose, Euro Speedy and Stateman during winter and summer period. Parameters employed to the study variety behavior included: production per area, fresh matter weight, presence of flower sprouts and moisture content. The parameters known as electrical variables, like consumption, demand and power factor, together with the treatment energy efficiency index were used to analyze the employed illumination technologies and light bulbs type. Results showed differences between weight of fresh flowers and moisture content for the flowers variety under consideration. Productivity per unit area was noticed to be larger for discharge technology when compared with filament bulbs, for both varieties being tested. The lowest flower sprout occurrence was associated to the discharge technology with the exception of the variety Stateman produced with incandescent bulbs of 100 W in the winter plot. The unique exception related to discharge technology was associated to the White 23 W Integrated Compact Fluorescent bulb yielding 2.4% of flower sprouts compared with 0% of other bulb types associated to the production of the variety Euro Speedy. It was noticed from the results that the yellow integrated compact

    The gypsy moth- Lymantria dispar (Linnaeus)-is a worldwide forest defoliator and is of two types: the European gypsy moth and the Asian gypsy moth. Because of multiple invasions of the Asian gypsy moth, the North American Plant Protection Organization officially approved Regional Standards for Phytosanitary Measures No. 33. Accordingly, special quarantine measures have been implemented for 30 special focused ports in the epidemic areas of the Asian gypsy moth, including China, which has imposed great inconvenience on export trade. The Asian gypsy moth and its related species (i.e., Lymantria monocha and Lymantria xylina ) intercepted at ports are usually at different life stages, making their identification difficult. Furthermore, Port quarantine requires speedy clearance. As such, it is difficult to identify the Asian gypsy moth and its related species only by their morphological characteristics in a speedy measure. Therefore, this study aimed to use molecular biology technology to rapidly identify the Asian gypsy moth and its related species based on the consistency of mitochondrial DNA in different life stages. We designed 10 pairs of specific primers from different fragments of the Asian gypsy moth and its related species, and their detection sensitivity met the need for rapid identification. In addition, we determined the optimal polymerase chain reaction amplification temperature of the 10 pairs of specific primers, including three pairs of specific primers for the Asian gypsy moth ( L. dispar asiatic ), four pairs of specific primers for the nun moth ( L. monocha ), and three pairs of specific primers for the casuarina moth ( L. xylina ). In conclusion, using our designed primers, direct rapid identification of the Asian gypsy moth and its related species is possible, and this advancement can help improve export trade in China.

  7. Influence of radiolysis and gas-liquid partition of I-131 in accumulated water on late phase source terms at Fukushima NPP accident

    Hidaka, Akihide

    2014-01-01

    In the process of core cooling at Fukushima Daiichi nuclear power plants accident, large amount of contaminated water was accumulated in the basements of the reactor buildings at Units 1 to 4. The present study estimated the quantities of I-131 and Cs-137 in the water as of late March based on the press-opened data. The estimated ratios of I-131 and Cs-137 quantities to the core inventories are 0.51%, 0.85% at Unit 1, 74%, 38% at Unit 2 and 26%, 18% at Unit 3, respectively. According to the Henry's law, certain fraction of iodine in water could be released to atmosphere due to gas-liquid partition and contribute to increase in the release to environment. A lot of evaluations for I-131 release have been performed so far by severe accident codes such as MELCOR or the reverse estimation with atmospheric dispersion code such as SPEEDI using the monitoring data. The SPEEDI reverse predicted significant release until March 26 while no prediction in MELCOR after March 17. The present study showed that iodine release from accumulated water due to radiolytic conversion from I - to I 2 and gas-liquid partition of I 2 may explain the release between March 17 and 26. This strongly suggests a need for improvement of current MELCOR approach which treats the release only from containment breaks for several days after the core melt. The study also indicates that the release of radioactive iodine from accumulated water in the basements of reactor buildings could become a great concern for the consequence of Fukushima accident.

    2008-02-01

    The biogeochemistry of sedimentary sulfur was investigated on the continental shelf off central Chile at water depths between 24 and 88 m under partial influence of an oxygen minimum zone. Dissolved and solid iron and sulfur species, including the sulfur intermediates sulfite, thiosulfate, and elemental sulfur, were analyzed at high resolution in the top 20 cm. All stations were characterized by high rates of sulfate reduction, but only the sediments within the Bay of Concepción contained dissolved sulfide. Due to advection and/or in-situ reoxidation of sulfide, dissolved sulfate was close to bottom water values. Whereas the concentrations of sulfite and thiosulfate were mostly in the submicromolar range, elemental sulfur was by far the dominant sulfur intermediate. Although the large nitrate- and sulfur-storing bacteria Thioploca were abundant, the major part of S 0 was located extracellularly. The distribution of sulfur species and dissolved iron suggests the reaction of sulfide with FeOOH as an important pathway for sulfide oxidation and sulfur intermediate formation. This is in agreement with the sulfur isotope composition of co-existing elemental sulfur and iron monosulfides. In the Bay of Concepción, sulfur isotope data suggest that pyrite formation proceeds via the reaction of FeS with polysulfides or H 2S. At the shelf stations, on the other hand, pyrite was significantly depleted in 34S relative to its potential precursors FeS and S 0. Isotope mass balance considerations suggest further that pyritization at depth includes light sulfide, potentially originating from bacterial sulfur disproportionation. The δ 34S-values of pyrite down to -38‰ vs. V-CDT are among the lightest found in organic-rich marine sediments. Seasonal variations in the sulfur isotope composition of dissolved sulfate indicated a dynamic non-steady-state sulfur cycle in the surface sediments. The 18O content of porewater sulfate increased with depth at all sites compared to the

    Full Text Available The 2013 World Health Organization Status Report on Road Safety estimated that approximately 1.24 million deaths occur annually due to road traffic crashes with most of the burden falling on low- and middle-income countries. The objective of this research is to study the prevalence of road traffic crashes in Mekelle, Tigray, Northern Ethiopia and to identify risk factors with the ultimate goal of informing prevention activities and policies.This study used a cross-sectional design to measure the prevalence and factors associated with road traffic crashes among 4-wheeled minibus (n = 130 and 3-wheeled Bajaj (n = 582 taxi drivers in Mekelle, Ethiopia. Bivariate and multivariate logistic regression were used to evaluate the association between risk factors and drivers' involvement in a road traffic crash within the 3 years prior to the survey.Among the 712 taxi drivers, 26.4% (n = 188 of them reported involvement in a road traffic crash within the past 3 years. Drivers who listened to mass media had decreased likelihood of road traffic crash involvement (AOR = 0.51, 0.33-0.78, while speedy driving (AOR = 4.57, 3.05-7.44, receipt of a prior traffic punishment (AOR = 4.57, 2.67-7.85, and driving a mechanically faulty taxi (AOR = 4.91, 2.81-8.61 were strongly associated with road traffic crash involvement. Receiving mobile phone calls while driving (AOR = 1.91, 1.24-2.92 and history of alcohol use (AOR = 1.51, 1.00-2.28 were also associated with higher odds of road traffic crash involvement.The results of this study show that taxi drivers in Mekelle habitually place themselves at increased risk of road traffic crashes by violating traffic laws, especially related to speedy driving, mobile phone use, and taxi maintenance. This research can be used to support re-evaluation of the type, severity, and enforcement of traffic violation penalties.

    The ^18O signal preserved in paleo-archives (e.g. speleothem, tree ring cellulose, ice cores) is widely used to reconstruct precipitation or temperature. In the tropics, the inverse relationship between precipitation ^18O and rainfall amount, namely "amount effect" [Dansgaard, Tellus, 1964], is often used to interpret precipitation ^18O. However, recent studies have shown that precipitation ^18O is also influenced by precipitation type [Kurita et al, JGR, 2009; Moerman et al, EPSL, 2013], and recent observations indicate that it is negatively correlated with the fraction of precipitation associated with stratiform clouds [Aggarwal et al, Nature Geosci, 2016]. It is thus important to determine to what extent isotope-enabled climate models can reproduce these relationships. Here we do so using output from LMDZ, CAM2, and isoGSM from the Stable Water Isotope Intercomparison Group, Phase 2 (SWING2) project and results of SPEEDY-IER [Dee et al, JGR, 2015] from an AMIP-style experiment. The results show that these models simulate the "amount effect" well in the tropics, and the relationship between precipitation ^18O and precipitation is reversed in many places in mid-latitudes, in accordance with observations [Bowen, JGR, 2008]. Also, these models can all reproduce the negative correlation between monthly precipitation ^18O and stratiform precipitation proportion in mid-latitude (30°N-50°N; 50°S-30°S), but in the tropics (30°S-30°N), models show a positive correlation instead. The reason for this bias will be investigated within idealized experiments with SPEEDY-IER. The correct simulations of the impact of convective activity on precipitation ^18O in isotope-enabled models will improve our interpretation of paleoclimate proxies with respect to hydroclimate variability.

    Tasks involved in the implementation of the Nuclear Waste Policy Act are discussed. The need for speedy action on applications to deal with spent fuel storage problems is stressed. The problems faced by the Virginia Electric and Power Company, where full core discharge capability at the 1600-megawatt Surry power station is expected to be reached in early 1986, are reviewed. It is pointed out that although the Nuclear Waste Policy Act does not apply in this case, the problems illustrate the situation that may be faced after the Act is implemented. Problems involved in intro-utility transhipments and dry cask storage of spent fuel from Surry, including transportation ordinances at state and local levels and approval for the use of dry casks for storage, are reported. The suggestion that dry casks be used for interim storage and eventual transport to monitored retrievable storage facilities or permanent storage sites is considered. It is pointed out that data from a proposed 3-utility demonstration program of dry cask storage of consolidated fuels and the storage of fuels in air should give information applicable to the timely implementation of the Nuclear Waste Policy Act

    Some of the Indian Railway bridges require reconstruction for electrification and expansion of railway tracks. Dismantling of bridge within time schedule in densely populated area requires controlled and pre-planned blasting methodology for safe pulling down of the structure and quick removal of blasted debris for fast restoration of tracks and smooth plying of trains. The three arched railway bridge (Bridge No. 61) located between Sahibganj and Karamtola cases one such example where the bridge was dismantled and the track was restored within 4 h of blasting, though the stipulated block period for demolition and restoration of tracks was 6 h. The 25.48 m long three-arched bridge was drilled and blasted with 225 number of blastholes (32 mm diameter) and 100 kg explosive (25 mm diameter). Length of blastholes varied between 0.5 and 1.8 m with blast geometry of 0.3-0.35 m burden and 0.33 m spacing. This paper deals with the conceptual and theoretical model developed for identification of the key locations for drilling and implementation of the same. It also discusses about the precautionary measures and the drilling pattern adopted for quick demolition and speedy restoration of tracks.

    Nano-scale carbon systems are emerging alternatives in drug delivery and bioimaging applications of which they gradually replace the quantum dots characterized by toxic heavy metal content in the latter application. The work intended to use carbon nanospheres synthesized from biowaste Sago bark for cancer cell imaging applications. This study synthesised carbon nanospheres from biowaste Sago bark using a catalyst-free pyrolysis technique. The nanospheres were functionalized with fluorescent dye coumarin-6 for cell imaging. Fluorescent nanosytems were characterized by field emission scanning electron microscopy-energy dispersive X ray, photon correlation spectroscopy and fourier transform infrared spectroscopy techniques. The average size of carbon nanospheres ranged between 30 and 40 nm with zeta potential of -26.8 ± 1.87 mV. The percentage viability of cancer cells on exposure to nanospheres varied from 91- 89 % for N2a cells and 90-85 % for A-375 cells respectively. Speedy uptake of the fluorescent nanospheres in both N2a and A-375 cells was observed within two hours of exposure. Novel fluorescent carbon nanosystem design following waste-to-wealth approach exhibited promising potential in cancer cell imaging applications.

    Legumes play a vital role in ensuring global nutritional food security and improving soil quality through nitrogen fixation. Accelerated higher genetic gains is required to meet the demand of ever increasing global population. In recent years, speedy developments have been witnessed in legume genomics due to advancements in next-generation sequencing (NGS) and high-throughput genotyping technologies. Reference genome sequences for many legume crops have been reported in the last 5 years. The availability of the draft genome sequences and re-sequencing of elite genotypes for several important legume crops have made it possible to identify structural variations at large scale. Availability of large-scale genomic resources and low-cost and high-throughput genotyping technologies are enhancing the efficiency and resolution of genetic mapping and marker-trait association studies. Most importantly, deployment of molecular breeding approaches has resulted in development of improved lines in some legume crops such as chickpea and groundnut. In order to support genomics-driven crop improvement at a fast pace, the deployment of breeder-friendly genomics and decision support tools seems appear to be critical in breeding programs in developing countries. This review provides an overview of emerging genomics and informatics tools/approaches that will be the key driving force for accelerating genomics-assisted breeding and ultimately ensuring nutritional and food security in developing countries.

    The Heavy Water Plant at Manuguru is designed to produce 185 MTY of nuclear grade heavy water based on bithermal H 2 S-H 2 O exchange process and handles large inventory of H 2 S gas (about 400 MT). As H 2 S gas is very toxic, corrosive and hazardous in nature, extreme care has been taken in the design of plant, selection of equipment and materials adhering to stringent fabrication procedures and codes to ensure the production of heavy water in a safe manner. This paper highlights the improvements done at Heavy Water Plant (Manuguru) to increase the standards of environmental protection. The safety assessment of a hazardous plant is a continuous process. Apart from the extreme care taken in the design, construction, commissioning and operation of the plant, review of each and every safety related unusual occurrence by various levels of review committees as stipulated and speedy implementation of the recommendations goes in a long way in increasing the standards of environmental protection

    Concrete usage in Construction becomes more common in this speedy world. Despite its benefits, concrete often exhibits crack which appear due to stresses. Larger cracks cause Structural integrity problems and smaller cracks may result in durability issues. A novel environmental friendly strategy to restore or remediate cracks formed in the structures is bio-mineralization of calcium carbonate using microbes such as Bacillus Subtilis (used in this study), as manual repair and maintenance is costly. In this Paper, an idea of using Super Absorbent Polymer in Bacterial Concrete was analysed which increases the strength and durability properties of concrete and also which acts as a protection to bacteria, where Self-Healing nature is viewed. In the span of 90 days, the results of Bacterial concrete cured under normal water providing nutrients inside with SAP shows healing up to 74 % and without SAP displays 49 % and when it is cured under nutrient medium, Bacterial Concrete having SAP displays healing up to 66 %, whereas without SAP it displays 57.4% of healing. During the observation it is discernible that the crack width ranging from 0.10 mm near 0.45 mm show better self-healing capacity. XRD analysis displays the presence of Calcium carbonate precipitation in cracks.

    An advanced LWR with hard neutron spectrum, FLWR, aims at efficient and flexible utilization of nuclear resources by evolving its fuel assembly design keeping the same core configuration. A proposed evolution process of the design toward a sustainable fuel cycle is composed of three stages, the first one based on the LWR fuel cycle infrastructures, the second one for transitioning from the LWR fuel cycle to the FR fuel cycle, and the third one based on the FR fuel cycle infrastructures. For the first stage, a fuel assembly design concept named FLWR/MIX has been developed in which enriched UO 2 fuel rods are arranged in the peripheral region of the assembly, surrounding the MOX fuel rods in the central region. The FLWR/MIX design realizes a breeder type operation under the framework of the LWR-MOX technologies and there experience. A modified FLWR/MIX design with low Pu inventory for the second stage has a potential of high Puf conversion ratio of 1.1 and can contribute to smooth and speedy transition from the LWR fuel cycle to the FR fuel cycle. For the third stage, the FLWR/MIX design is extended into a design with natural UO 2 fuel rods to realize multiple Pu recycling keeping a Puf conversion ratio of around 1.0. (author)

    Full Text Available ABSTRACT Purpose: To determine the predictive factors for postoperative urinary incontinence (UI following holmium laser enucleation of the prostate (HoLEP during the initial learning period. Patients and Methods: We evaluated 127 patients with benign prostatic hyperplasia who underwent HoLEP between January 2011 and December 2013. We recorded clinical variables, including blood loss, serum prostate-specific antigen levels, and the presence or absence of UI. Blood loss was estimated as a decline in postoperative hemoglobin levels. The predictive factors for postoperative UI were determined using a multivariable logistic regression analysis. Results: Postoperative UI occurred in 31 patients (24.4%, but it cured in 29 patients (93.5% after a mean duration of 12 weeks. Enucleation time >100 min (p=0.043 and blood loss >2.5g/dL (p=0.032 were identified as significant and independent risk factors for postoperative UI. Conclusions: Longer enucleation time and increased blood loss were independent predictors of postoperative UI in patients who underwent HoLEP during the initial learning period. Surgeons in training should take care to perform speedy enucleation maneuver with hemostasis.

    The team of five welders and five mechanics, represented by Pascal Mésenge (right) and Fabrice Multon (left), worked during two week-ends to repair the two ROCLA. At the centre, Oliver Boettcher, technical manager for the robot. The two LHC magnet transport robots ROCLA have recently been repaired after cracks were found in the welds of their load-bearing structure. The Safety Commission suspended the use of one robot and limited the operation conditions of the other. These vehicles are used intensively for the transport of the LHC cryodipoles between the test and the assembly facilities SM18 and SMA18. As a consequence, a speedy solution had to be implemented to minimize the potential disruption to the LHC schedule. Appropriate CERN resources were immediately focused on the problem. As soon as TS/MME had designed a reinforced gantry support, the necessary raw material was ordered. Less than 10 days were required to get the two ROCLA robots operating again. This included 2 full weekends, many extra hours a...

    2005-01-01

    In recent years, passenger train speed and freight train load have increased to enhance efficiency of rail road transportation. These trends have increased the severity of rail service conditions, calling for rails with greater wear resistance, strength and fatigue behaviour. In the United Stated and Europe, track site weld rails are made entirely by aluminothermic process. This work describes the results of experimental study conducted on bending fatigue strength of plain rails and aluminothermic welded rails with preheating procedures (oxipropane and air-induced propane) approved by railways authorities. Compliance with the required fatigue strength shall be ascertained by 4 point pulsating bending test in accordance with European standards by aluminothermic welding in rails. The locati method, based in the empirical Miner's law about the cumulative damage on a fatigue tested material, allows, once known the Wohler curve of the welding process in use to settle the fatigue tensile limit at 50% with only one test. The values obtained at 2.10''6 cycles for plain rails (S f =353 MPa), oxipropane preheated aluminothermic weld rails (S f =225 MPa), and propane-air induced aluminothermic weld rails (S f =210 MPa) are very similar to those resulting from test method stated in the European Standard. From our point of view and due to its ease, speediness and savings, this is the most suitable test to check the quality and compare the aluminothermic processes in use. (Author) 15 refs

    An ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) method integrating multi-ingredients determination and fingerprint analysis has been established for quality assessment and control of leaves from Ilex latifolia. The method possesses the advantages of speediness, efficiency, accuracy, and allows the multi-ingredients determination and fingerprint analysis in one chromatographic run within 13min. Multi-ingredients determination was performed based on the extracted ion chromatograms of the exact pseudo-molecular ions (with a 0.01Da window), and fingerprint analysis was performed based on the base peak chromatograms, obtained by negative-ion electrospray ionization QTOF-MS. The method validation results demonstrated our developed method possessing desirable specificity, linearity, precision and accuracy. The method was utilized to analyze 22 I. latifolia samples from different origins. The quality assessment was achieved by using both similarity analysis (SA) and principal component analysis (PCA), and the results from SA were consistent with those from PCA. Our experimental results demonstrate that the strategy integrated multi-ingredients determination and fingerprint analysis using UPLC-QTOF-MS technique is a useful approach for rapid pharmaceutical analysis, with promising prospects for the differentiation of origin, the determination of authenticity, and the overall quality assessment of herbal medicines.

    The consequence of thermal radiation in laminar natural convective hydromagnetic flow of viscous incompressible fluid past a vertical cone with mass transfer under the influence of chemical reaction with heat source/sink is presented here. The surface of the cone is focused to a variable wall temperature (VWT) and wall concentration (VWC). The fluid considered here is a gray absorbing and emitting, but non-scattering medium. The boundary layer dimensionless equations governing the flow are solved by an implicit finite-difference scheme of Crank-Nicolson which has speedy convergence and stable. This method converts the dimensionless equations into a system of tri-diagonal equations and which are then solved by using well known Thomas algorithm. Numerical solutions are obtained for momentum, temperature, concentration, local and average shear stress, heat and mass transfer rates for various values of parameters Pr, Sc, λ, Δ, Rd are established with graphical representations. We observed that the liquid velocity decreased for higher values of Prandtl and Schmidt numbers. The temperature is boost up for decreasing values of Schimdt and Prandtl numbers. The enhancement in radiative parameter gives more heat to liquid due to which temperature is enhanced significantly.

    In order to study the effects of exposure to a small dose of radiation during the fetal period upon behavior and growth, 2 groups of 13-day-old fetal mice were irradiated. One group consisted of 18 fetal mice given 25 R and the other of 15 given 100 R. The control group consisted of 18 fetal mice 13 days old. After birth they were all placed in the center of an open area (50 x 50 x 25 cm) for 3 minutes so as to determine the number of squares traversed ad lib. (the number which their extremities traversed for 3 minutes) and the time day when they began walking and grooming. After they were observed for 3 minutes, the time at which reflex actions such as speedy righting and auditory startle were observed was confirmed. There were no differnces between the 25 R-irradiated group and the control group. In the 100 R-irradiated group, walking was observed earlier than in the control group, and the number of squares traversed increased.

    Full Text Available The paper outlines the importance of balanced management of hard and soft key success factors, combining the economic logic of corporate performance and human capital through an integrated approach to mergers and acquisitions. The study, based on a questionnaire and interviews, suggests that the achievement level ofmergers and acquisitions’ objectives of acquiring companies in Slovenia should be comparable to findings of similar studies; namely, the objectives that drove the deal were met only half the time. The results indicate that five hard success factors – a professional target search and due diligence, a realistic assessment of synergies, theright mix of financial sources, a detailed post-acquisition integration plan already prepared in the pre-deal phase and its speedy implementation – and five soft success factors – a new “combined” organizational culture, a competent management team, innovative employees, efficient and consistent communication and a creative business environment – are becoming increasingly relevant. Even though they differ in their importance for individual companies in the sample, they are all considered essential to increasing the success rate of corporate combinations

    A method of microwave digestion technique-flame atomic absorption spectrometry was proposed to determine the total contents of Cu, Zn, Pb, Cd, Cr and Ni in five different kinds of waste bag filters from a steel plant. The digestion effects of the six acid systems on the heavy metals digestion were studied for the first time. The relative standard deviation (RSD) of the method was between 1.02% and 9.35%, and the recovery rates obtained by standard addition method ranged from 87.7% to 105.6%. The results indicated that the proposed method exhibited the advantages of simplicity, speediness, accuracy and repeatability, and it was suitable for determining the metal elements of the waste bag filter. The results also showed that different digestion systems should be used according to different waste bag filters. The waste bag filter samples from different production processes had different metal elements content. The Pb and Zn were the highest in the waste bag filters, while the Cu, Ni, Cd and Cr were relatively lower. These determination results provided the scientific data for further treatment and disposal of the waste bag filter.

    Natural movements and force feedback are important elements in using teleoperated equipment if complex and speedy manipulation tasks are to be accomplished in remote and/or hazardous environments, such as hot cells, glove boxes, decommissioning, explosives disarmament, and space to name a few. In order to achieve this end the research presented in this paper has developed an admittance type exoskeleton like multi-fingered haptic hand user interface that secures the user’s palm and provides 3-dimensional force feedback to the user’s fingertips. Atypical to conventional haptic hand user interfaces that limit themselves to integrating the human hand’s characteristics just into the system’s mechanical design this system also perpetuates that inspiration into the designed user interface’s controller. This is achieved by manifesting the property differences of manipulation and grasping activities as they pertain to the human hand into a nonlinear master-slave force relationship. The results presented in this paper show that the admittance-type system has sufficient bandwidth that it appears nearly transparent to the user when the user is in free motion and when the system is subjected to a manipulation task, increased performance is achieved using the nonlinear force relationship compared to the traditional linear scaling techniques implemented in the vast majority of systems.

    Mannakkara, Sandeeka; Wilkinson, Suzanne

    This paper looks at developing build back better (BBB) principles for economic recovery using the 2009 Victorian bushfires in Australia as a case study. The concept behind BBB-based economic recovery is to rejuvenate the economy in disaster-affected communities along with rebuilding to create resilient sustainable communities. A review of the literature identified several principles that can be applied to economic recovery to build back better. Data were collected in 2010 and 2011 by conducting semi- structured interviews with stakeholders who were directly involved in the Victorian bushfires recovery efforts, along with reports and other documentation. The recovery in Victoria displayed the use of BBB-based initiatives for economic recovery. The successes and shortcomings contributed to the creation of a modified list of BBB principles for economic recovery, including: creating an economic strategy based on thorough data collection; providing effective funding through grants and flexible low-interest loans; establishing business advice and mentoring services; providing incentives for businesses; assisting speedy rebuilding of business buildings; providing subsidised employee training and up-skilling programmes; and promoting local businesses through advertising.

    Full Text Available There is a global outcry over the speedy deterioration of structures in oil and gas facilities. While marine environment is considered the leading factor in the deterioration of offshore structures, there is no single factor considered as the main cause of the problem in onshore structures. Therefore, the aim of this paper is to present the result of global survey on the major factors causing the deterioration of concrete structures in onshore oil and gas facilities. To realize the objectives of the paper, an e-questionnaire was administered through two International LinkedIn groups with a membership mainly dominated by experts in onshore oil and gas facilities. 159 respondents completed the questionnaires, and the reliability of the responses was calculated to be 0.950 which is considered excellent. Relative importance index was used in ranking the factors, and it was observed that environmental factors ranked as the dominant factors causing the deterioration of concrete structures in onshore process plants. Another important finding in the study is the role that experience plays on the perception of experts on the causes of defects on concrete structures.

    In arid regions, primary pollutants may contribute to the increase of ozone levels and cause negative effects on biotic health. This study investigates the use of adaptive neuro-fuzzy inference system (ANFIS) for ozone prediction. The initial fuzzy inference system is developed by using fuzzy C-means (FCM) and subtractive clustering (SC) algorithms, which determines the important rules, increases generalization capability of the fuzzy inference system, reduces computational needs, and ensures speedy model development. The study area is located in the Empty Quarter of Saudi Arabia, which is considered as a source of huge potential for oil and gas field development. The developed clustering algorithm-based ANFIS model used meteorological data and derived meteorological data, along with NO and NO₂ concentrations and their transformations, as inputs. The root mean square error and Willmott's index of agreement of the FCM- and SC-based ANFIS models are 3.5 ppbv and 0.99, and 8.9 ppbv and 0.95, respectively. Based on the analysis of the performance measures and regression error characteristic curves, it is concluded that the FCM-based ANFIS model outperforms the SC-based ANFIS model.

    This paper presents the method commonly applied in Poland of forecasting the thermal character of an underground high-level radioactive waste repository. It is used for optimizing the mine excavation configuration as well as the order of storage. This method is shown with an example of the research results for the central radioactive waste repository. A short description of the designed repository as well as a comparison of expenditure for underground and surface repositories is given. The method shown in this paper of forecasting the temperature rise in the repository is based on the superposition of the analytical integral solutions of the heat conductivity equation for a single canister - the heat source. The detailed computer tabulation of these solutions enables forecasting the possibility of fast temperature increase at any repository point and at any time, taking into consideration localization and storage time for each of the thousands of stored canisters individually. In the repository design phase this allows the speedy investigation of various variants in the configuration of the placement and transportation corridors as well as the choice of a variant ensuring the best utilization of the repository area and also suitable working conditions for both mining and placement crews.

    One of Image indexing techniques is the Content-Based Image Retrieval which is an efficient way for retrieving images from the image database automatically based on their visual contents such as colour, texture, and shape. In this paper will be discuss how using content-based image retrieval (CBIR) method by colour feature extraction and similarity checking. By dividing the query image and all images in the database into pieces and extract the features of each part separately and comparing the corresponding portions in order to increase the accuracy in the retrieval. The proposed approach is based on the use of fuzzy sets, to overcome the problem of curse of dimensionality. The contribution of colour of each pixel is associated to all the bins in the histogram using fuzzy-set membership functions. As a result, the Fuzzy Colour Histogram (FCH), outperformed the Conventional Colour Histogram (CCH) in image retrieving, due to its speedy results, where were images represented as signatures that took less size of memory, depending on the number of divisions. The results also showed that FCH is less sensitive and more robust to brightness changes than the CCH with better retrieval recall values.

    During an emerging health crisis like the 2014 Ebola outbreak in West Africa, communicating with communities to learn from them and to provide timely information can be a challenge. Insight into community thinking, however, is crucial for developing appropriate communication content and strategies and for monitoring the progress of the emergency response. In November 2014, the Health Communication Capacity Collaborative partnered with GeoPoll to implement a Short Message Service (SMS)-based survey that could create a link with affected communities and help guide the communication response to Ebola. The ideation metatheory of communication and behavior change guided the design of the survey questionnaire, which produced critical insights into trusted sources of information, knowledge of transmission modes, and perceived risks-all factors relevant to the design of an effective communication response that further catalyzed ongoing community actions. The use of GeoPoll's infrastructure for data collection proved a crucial source of almost-real-time data. It allowed for rapid data collection and processing under chaotic field conditions. Though not a replacement for standard survey methodologies, SMS surveys can provide quick answers within a larger research process to decide on immediate steps for communication strategies when the demand for speedy emergency response is high. They can also help frame additional research as the response evolves and overall monitor the pulse of the situation at any point in time.

    The Great East Japan Earthquake on March 11, 2011 is said to be a once-in-1000-year catastrophic quake. The Tsunami triggered by the earthquake destroyed broad coastal areas in northeast Japan. As recovery from the earthquake proceeds, the demand for new road construction, housing hill development, and residential construction is rapidly increasing. Culture plays a critical role in the district's recovery. For that reason, before development, cultural properties in the corresponding districts must be urgently investigated. This is a must, although balancing cultural recovery with rapid economic recovery is no easy task. With this in mind, we have developed a new system focusing on speedy archaeological investigation and adequate documentation. The authors reexamined the existing investigation process to categorize tasks into two types: those that must be done only at archaeological sites (site A) and ones available at other places (site B). We then formulated a scheme where the tasks on both sites are performed simultaneously in parallel over the network. Experiments are ongoing. This presentation reports the process and issues of our research and development.

    Crisis management section members of Japan Nuclear Cycle Development Institute (JNC) Tokai Works had implemented two types of trainings against terrorism in last Japanese fiscal year and improved the countermeasure against the terrorism. In this fiscal year we trained against the new type of terrorism in the period of about 1 year later of a series of attacks on America by terrorism. As a result of the training some points which need further improvements and new weak points have been availed as follows. (1) Enlightenment of workers' senses against terrorism. Few members of the Emergency Control Center, workers and guards looked tensionless in the training. The sense against terrorism needs to be enlightened. (2) Speediness of initial response. In this training the events using a car went on more rapidly than expected. The rapid response to counter terrorism needs to be examined. (3) Improvement of fundamental countermeasures. The fundamental response of the workers to the terrorism under limited condition before the guard authorities' arrival has been improved further more through the education and trainings. (4) Completeness of the prevention of terrorism. After terrorism occurs, Tokai Works is helpless until the guard authorities arrive. First of all the measure to avoid terrorism occurrence is important. (5) Strengthen the cooperation with the guard authorities. Besides completeness of the prevention of terrorism it is necessary to cope with the guard authorities at ordinary times against an emergency. (author)

    The purpose of this paper is to present the variational method for geometric contours which helps the level set function remain close to the sign distance function, therefor it remove the need of expensive re-initialization procedure and thus, level set method is applied on magnetic resonance images (MRI) to track the irregularities in them as medical imaging plays a substantial part in the treatment, therapy and diagnosis of various organs, tumors and various abnormalities. It favors the patient with more speedy and decisive disease controlling with lesser side effects. The geometrical shape, the tumor's size and tissue's abnormal growth can be calculated by the segmentation of that particular image. It is still a great challenge for the researchers to tackle with an automatic segmentation in the medical imaging. Based on the texture analysis, different images are processed by optimization of level set segmentation. Traditionally, optimization was manual for every image where each parameter is selected one after another. By applying fuzzy logic, the segmentation of image is correlated based on texture features, to make it automatic and more effective. There is no initialization of parameters and it works like an intelligent system. It segments the different MRI images without tuning the level set parameters and give optimized results for all MRI's.

    Shape/phase coexistence and the evolution of structure in the region around ^152Sm have recently been of great interest. Experiments performed at WNSL, Yale University, measured the lifetime of low spin states in a target of ^150Sm with the recoil distance method (RDM) and the Doppler-shift attenuation method (DSAM). The low spin states, both yrast and non-yrast, were populated via Coulomb excitation with a beam of ^16O. The experiments were performed with the NYPD plunger in conjunction with the SPEEDY γ-ray array. The SCARY array of solar cells was used to detect backward scattered projectiles, selecting forward flying Coulomb excited target nuclei. The measured lifetimes yield, for example, B(E2) values for transitions such as the 2^+2 arrow 2^+1 and the 2^+3 arrow 0^+_1. Data from the RDM measurment and the DSAM experiment will be presented. This work was supported by the US DOE under grants DE-FG02-91ER-40609 and DE-FG02-88ER-40417.

    This study investigated (1) whether nonlinguistic processing speed predicts nonverbal IQ in TD children and children with SLI and (2) if the proposed relationship is different at two time points. The participants consisted of a subset of a longitudinal dataset, 55 typically developing children and 55 children with SLI. Children completed four nonverbal speed tasks and four subtests of the WISC-III. The WISC-III subtests requiring timed and untimed responses were examined separately. Linear mixed model analyses indicated that in both groups, processing speed predicted nonverbal IQ subtests that reward speedy responses, but not IQ subtests that do not. The relationships between processing speed and IQ with speed bonuses did not differ at grades 3 and 8, and these relationships also were not significantly different in children with SLI and their TD peers. The results suggest that the presence of processing speed limitations in many children with SLI raises questions about the utility of timed nonverbal IQ measures as tools for diagnosis of SLI. Future studies should investigate other cognitive assessments that could be used as inclusionary criteria for SLI. The reader will be able to (1) describe the relationship between processing speed and nonverbal IQ in children with TD and SLI and (2) discuss problems using an IQ criterion to diagnose children as having SLI.

    The data presented in this paper shows the spatiotemporal expansion of Dire Dawa City (eastern Ethiopia) and the ensuing land use land cover changes in its peri-urban areas between 1985 and 2015. The data were generated from satellite images of Thematic Mapper (TM), Enhanced Thematic Mapper-Plus (ETM+) and OLI (Operational Land Image) with path/raw value of 166/053 by using Arc GIS 10.1 software. The precision of the images was verified by geolocation data collected from ground control points by using Geographic Positioning System (GPS) receiver. Four LULC classes (built up area, vegetation, barren land and farmland) with their respective spatiotemporal dimensions were clearly identified in the analysis. Built up area had shown an overall annual increment of 15.8% (82 ha per year) from 517 ha in 1985 to 2976 ha in 2015. Expansion took place in all directions but it was more pronounced along the main road towards other nearby towns, recently established business/service areas and the Industrial Park. Barren land, farmland and vegetation areas showed speedy decline over the years.

    Conventional bricks are the most elementary building materials for houses construction. However, the rapid growth in today’s construction industry has obliged the civil engineers in searching for a new building technique that may result in even greater economy, more efficient and durable as an alternative for the conventional brick. Moreover, the high demands for having a speedy and less labour and cost building systems is one of the factor that cause the changes of the masonry conventional systems. These changes have led to improved constructability, performance, and cost as well. Several interlocking bricks has been developed and implemented in building constructions and a number of researches had studied the manufacturing of interlocking brick and its structural behaviour as load bearing and non-load bearing element. This technical paper aims to review the development of interlocking brick and its structural behaviour. In conclusion, the concept of interlocking system has been widely used as a replacement of the conventional system where it has been utilized either as load bearing or non-load bearing masonry system.

    Sovereign Wealth Funds (SWF) have different titles, goals and rules, but they share the underlying objective of helping governments deal with the problems created by large and variable revenues (mainly from energy or other commodity related sectors). In Kazakhstan, such a fund (the National Fund of the Republic of Kazakhstan (NFRK)) was established in 2000. This fund operates as both a stabilisation and a savings fund. The first test for the NFRK was 2007-2009 financial crisis, where the NFRK 'saved' the economy and guarantied its speedy recovery. The paper analyses the NFRK's operation up to 2007 and during the crisis years 2007-9, before drawing conclusions and implications for the future. Between 2001 and 2007 the NFRK conservatively accumulated assets, which proved to be useful in limiting the impact of the post-2007 crisis. However, the pre-2007 experience indicated structural weaknesses associated with discretionary executive authority and non-transparency. The paper concludes by observing that this history has created significant challenges for the future. - Highlights: > Expenditures of resource revenues should be consistent with the government's long-term plan to save for the future. > A system of indicators for the non-resource deficit is required. > Domestic investment provides more stability and economic resilience. > A transparent and accountable governance structure of the NFRK is required.

    A well-ordered porous three-phase boundary (TPB) was prepared with a polystyrene sphere as template and examined to improve the sensitivity of yttria-stabilized zirconia (YSZ)-based mixed-potential-type NO2 sensor due to the increase of the electrochemical reaction active sites. The shape of pore array on the YSZ substrate surface can be controlled through changing the concentration of the precursor solution (Zr(4+)/Y(3+) = 23 mol/L/4 mol/L) and treatment conditions. An ordered hemispherical array was obtained when CZr(4+) = 0.2 mol/L. The processed YSZ substrates were used to fabricate the sensors, and different sensitivities caused by different morphologies were tested. The sensor with well-ordered porous TPB exhibited the highest sensitivity to NO2 with a response value of 105 mV to 100 ppm of NO2, which is approximately twice as much as the smooth one. In addition, the sensor also showed good stability and speedy response kinetics. All these enhanced sensing properties might be due to the structure and morphology of the enlarged TPB.

    In order to study the effects of exposure to a small dose of radiation during the fetal period upon behavior and growth, 2 groups of 13-day-old fetal mice were irradiated. One group consisted of 18 fetal mice given 25 R and the other of 15 given 100 R. The control group consisted of 18 fetal mice 13 days old. After birth they were all placed in the center of an open area (50 x 50 x 25 cm) for 3 minutes so as to determine the number of squares traversed ad lib. (the number which their extremities traversed for 3 minutes) and the time day when they began walking and grooming. After they were observed for 3 minutes, the time at which reflex actions such as speedy righting and auditory startle were observed was confirmed. There were no differnces between the 25 R-irradiated group and the control group. In the 100 R-irradiated group, walking was observed earlier than in the control group, and the number of squares traversed increased. (Ichikawa, K.)

    Concerns about a lack of reproducibility of statistically significant results have recently been raised in many fields, and it has been argued that this lack comes at substantial economic costs. We here report the results from prediction markets set up to quantify the reproducibility of 44 studies published in prominent psychology journals and replicated in the Reproducibility Project: Psychology. The prediction markets predict the outcomes of the replications well and outperform a survey of market participants’ individual forecasts. This shows that prediction markets are a promising tool for assessing the reproducibility of published scientific results. The prediction markets also allow us to estimate probabilities for the hypotheses being true at different testing stages, which provides valuable information regarding the temporal dynamics of scientific discovery. We find that the hypotheses being tested in psychology typically have low prior probabilities of being true (median, 9%) and that a “statistically significant” finding needs to be confirmed in a well-powered replication to have a high probability of being true. We argue that prediction markets could be used to obtain speedy information about reproducibility at low cost and could potentially even be used to determine which studies to replicate to optimally allocate limited resources into replications.

    The purpose of this study was to assess the efficacy of instrumentation of C-shaped canals with ProTaper rotary system and traditional instruments by using micro-computed tomography (micro-CT). Twenty-four mandibular molars with C-shaped canals were selected in pairs and sorted equally into 2 groups, which were assigned for instrumentation by ProTaper rotary system (ProTaper group) or by K-files and Gates-Glidden burs (Hand Instrument group). Three-dimensional images were constructed by micro-CT. The volume of dentin removed, uninstrumented canal area, time taken for instrumentation, and iatrogenic error of instrumentation were investigated. Hand Instrument group showed greater amount of volumetric dentin removal and left less uninstrumented canal area than ProTaper group (P ProTaper group than for Hand Instrument group (P Hand Instrument group than for ProTaper group. It was concluded that ProTaper rotary system maintained the canal curvature with speediness and few procedural errors, whereas traditional instrumentation can clean more canal surface.

    2014-12-01

    Full Text Available Services composition is fundamental to software development in multi-service wireless sensor networks (WSNs. The quality of service (QoS of services composition applications (SCAs are confronted with severe challenges due to the open, dynamic, and complex natures of WSNs. Most previous research separated various QoS indices into different fields and studied them individually due to the computational complexity. This approach ignores the mutual influence between these QoS indices, and leads to a non-comprehensive and inaccurate analysis result. The universal generating function (UGF shows the speediness and precision in QoS analysis. However, only one QoS index at a time can be analyzed by the classic UGF. In order to efficiently analyze the comprehensive QoS of SCAs, this paper proposes an improved UGF technique—vector universal generating function (VUGF—which considers the relationship between multiple QoS indices, including security, and can simultaneously analyze multiple QoS indices. The numerical examples demonstrate that it can be used for the evaluation of the comprehensive QoS of SCAs subjected to the security constraint in WSNs. Therefore, it can be effectively applied to the optimal design of multi-service WSNs.

    Full Text Available Tumors occur in all domestic and wild animals. They are most often diagnosed in dogs and cats, and their numbers increase from year to year. In the recent years, cancer is believed to be the most frequent cause of pet deaths. A speedy and reliable diagnosis is of paramount importance because it enables the veterinarian to begin therapy and make a prognosis. The objective of an early diagnosis is to enable the detection of neoplastic diseases before the tumor spreads throughout the organism, consequently enabling the timely administration of therapy and providing greater chances for curing the animal. A tumor is diagnosed on the grounds of the anamnesis, clinical picture, and special diagnostic procedures. The most frequently applied diagnostic procedures are laboratory diagnostics, cytology, biopsy and pathohistology, imaging diagnostics (roentgenography and roentgenoscopy, ultrasound diagnostics, endoscopy, computer tomography, magnetic resonance, and scintigraphy and molecular diagnostics. Each of these methods has its advantages and faults in connection with costs, availability, sensitivity, specificity and quality of anatomic vs functional pictures. Every one of these techniques has its own field of implementation and each one provides different and additional information in connection with the nature and position of the primary lesion and the presence of metastases.

    The development of the hydrocarbon resources of the North Sea has resulted in both offshore and onshore environmental repercussions, involving the existing physical attributes of the sea and seabed, the coastline and adjoining land. The social and economic repercussions of the industry were equally widespread. The dramatic and speedy impact of the exploration and exploitation of the northern North Sea resources in the early 1970s, on the physical resources of Scotland was quickly realised together with the concern that any environmental and social damage to the physical and social fabric should be kept to a minimum. To this end, a wide range of research and other activities by central and local government, and other interested agencies was undertaken to extend existing knowledge on the marine and terrestrial environments that might be affected by the oil and gas industry. The outcome of these activities is summarized in this paper. The topics covered include a survey of the marine ecosystems of the North Sea, the fishing industry, the impact of oil pollution on seabirds and fish stocks, the ecology of the Scottish coastline and the impact of the petroleum industry on a selection of particular sites.

    Marfan syndrome is an autosomal dominant heritable disorder of the connective tissue, caused by mutations of the gene FBN1, which encodes fibrillin-1, a major component of the microfibrils of the extracellular matrix. Fibrillin-1 interacts with transforming growth factor-β (TGF-β), and dysregulated TGF-β signaling plays a major role in the development of connective tissue disease and familial aortic aneurysm and dissection, including Marfan syndrome. Losartan, an angiotensin II blocker, has the potential to reduce TGF-β signaling and is expected to be an additional therapeutic option. Clinical diagnosis is made using the Ghent nosology, which requires comprehensive patient assessment and has been proven to work well, but evaluation of some of the diagnostic criteria by a single physician is difficult and time-consuming. A Marfan clinic was established at the University of Tokyo Hospital in 2005, together with cardiologists, cardiac surgeons, pediatricians, orthopedists, and ophthalmologists in one place, for the purpose of speedy and accurate evaluation and diagnosis of Marfan syndrome. In this review, we discuss the recent progress in diagnosis and treatment of Marfan syndrome, and the characteristics of Japanese patients with Marfan syndrome. © 2014 Japan Pediatric Society.

    Full Text Available The design of low complexity sharp transition width Modified Discrete Fourier Transform (MDFT filter bank with perfect reconstruction (PR is proposed in this work. The current trends in technology require high data rates and speedy processing along with reduced power consumption, implementation complexity and chip area. Filters with sharp transition width are required for various applications in wireless communication. Frequency response masking (FRM technique is used to reduce the implementation complexity of sharp MDFT filter banks with PR. Further, to reduce the implementation complexity, the continuous coefficients of the filters in the MDFT filter banks are represented in discrete space using canonic signed digit (CSD. The multipliers in the filters are replaced by shifters and adders. The number of non-zero bits is reduced in the conversion process to minimize the number of adders and shifters required for the filter implementation. Hence the performances of the MDFT filter bank with PR may degrade. In this work, the performances of the MDFT filter banks with PR are improved using a hybrid Harmony-Gravitational search algorithm.

    A numerical simulation system SPEEDI-MP, which is applicable for various environmental studies, consists of dynamical models and material transport models for the atmospheric, terrestrial, and oceanic environments, meteorological and geographical databases for model inputs, and system utilities for file management, visualization, analysis, etc., using graphical user interfaces (GUIs). As a numerical simulation tool, a model coupling program (model coupler) has been developed. It controls parallel calculations of several models and data exchanges among them to realize the dynamical coupling of the models. It is applicable for any models with three-dimensional structured grid system, which is used by most environmental and hydrodynamic models. A coupled model system for water circulation has been constructed with atmosphere, ocean, wave, hydrology, and land-surface models using the model coupler. Performance tests of the coupled model system for water circulation were also carried out for the flood event at Saudi Arabia in January 2005 and the storm surge case by the hurricane KATRINA in August 2005.

    This review describes the adaptation of the plant virus-based transient expression system, magnICON(®) for the at-scale manufacturing of pharmaceutical proteins. The system utilizes so-called "deconstructed" viral vectors that rely on Agrobacterium-mediated systemic delivery into the plant cells for recombinant protein production. The system is also suitable for production of hetero-oligomeric proteins like immunoglobulins. By taking advantage of well established R&D tools for optimizing the expression of protein of interest using this system, product concepts can reach the manufacturing stage in highly competitive time periods. At the manufacturing stage, the system offers many remarkable features including rapid production cycles, high product yield, virtually unlimited scale-up potential, and flexibility for different manufacturing schemes. The magnICON system has been successfully adaptated to very different logistical manufacturing formats: (1) speedy production of multiple small batches of individualized pharmaceuticals proteins (e.g. antigens comprising individualized vaccines to treat NonHodgkin's Lymphoma patients) and (2) large-scale production of other pharmaceutical proteins such as therapeutic antibodies. General descriptions of the prototype GMP-compliant manufacturing processes and facilities for the product formats that are in preclinical and clinical testing are provided.

    The microprobe beamline of the Pohang Light Source (PLS) consists of main and second slits, a microprobe system, two ion chambers, a video-microscope, and a Si(Li) detector. These machine components must be controlled remodely through the computer system to make user's experiments precise and speedy. A real-time computer control system was developed to control and monitor these components. A VMEbus computer with an OS-9 real-time operating system was used for the low-level data acquisition and control. VME I/O modules were used for the step motor control and the scalar control. The software has a modular structure for the maximum performance and the easy maintenance. We developed the database, the I/O driver, and the control software. We used PC/Windows 95 for the data logging and the operator interface. Visual C{sup ++} was used for the graphical user interface programming. RS232C was used for the communication between the VME and the PC. (author)

  20. Concept Mapping for Higher Order Thinking

    Full Text Available Engineering education is facing a changing world in which how one thinks is becoming more important than what one thinks; that is, our course content is important but constantly changing and we need to help students learn how to think about that content.Today’s students have grown accustomed to immediate rewards, multi-channel stimuli, and rapid-fire communications.  As a result, they are often impatient and suffer a lack of focus. When reflection is called for in the learning process - a time consuming practice - students may find it difficult to overcome the conflict between their typically speedy management of priorities and the focused, time-intensive thinking required to acquire a strong foundation of declarative knowledge.Therefore, the exploration of tools to facilitate the formation of deep knowledge structures is essential. One instructional strategy that shows promise is the use of concept mapping, a learning activity that requires students to explain their understanding of important ideas and the relationships among those ideas.  This paper describes a pilot project to integrate concept mapping into a Mechanical Engineering Course and the preliminary results of that project.This project has been established within the Working Group of “Tools for Developing High Order Thinking Skills”, of the Portuguese Society for Engineering Education, in which the first author is the leader and the other two co-authors, are working group members

    Full Text Available In this article, we present our hypotheses regarding the divergence in the development of common-property regimes between Eastern and Western Europe. The latter area developed formalized arrangements for the collective exploitation of natural resources particularly early, and it was chosen not only by farmers, but also in the cities – by craftsmen – to deal with the economic and social problems during the late medieval and early modern times. In the East the development of such institutions for collective action started – we believe – much later, due to a number of factors. Whereas in the West population growth and urbanization occurred together with a speedy commercialization of the economy, putting pressure on natural resources and hence leading to an increasing demand by peasants to formalize the collective use of their land, the peasants east of the Elbe River lacked the agency to demand such change in the governance regime of their land. They were limited in their behaviour by the strictures of the second serfdom, which was accompanied by lesser urbanization and commercialization. In this article, we offer some explanatory frameworks to understand and study this long-term development – or lack thereof – of institutions for collective action across the European continent.

    Hongkong Route 3 construction under the BOT scheme (covering the basic plan, design, and construction, and the management of the completed tunnel as a private, toll facility) is described. The new route aims at dealing with aggravating traffic conditions as part of the major highway network joining Hongkong and Guanzhou, China proper. It is a dual three lane system, consisting of a 3.7km-long road tunnel, a 1.5km-long southern approach, and a 6.3km-long northern approach. Geologically speaking, the tunnel section as a whole is on a relatively hard and stable basement made of fine-grain granite and granitic diorite. Also introduced in this report are the project-executing organization and the flow of tendering under the BOT scheme. Since the shortening of the construction time is quite important in the 30-year BOT franchise period, rapid boring technologies were introduced into tunnel excavation. The 5.6m long-hole blasting enabled a maximum monthly progress of 460m. For the assurance of high boring accuracy and cycle time reduction, a fully automatic boring machine was adopted for speedy positioning and marking. An emulsion-type explosive was used, which can be pump-fed under pressure, for shortening the charging time. 5 figs.

    Full Text Available Bicycles are known to be rich source of kinetic energy, some of which is available for harvesting during speedy and balanced maneuvers by the user. A conventional dynamo attached to the rim can generate a large amount of output power at an expense of extra energy input from the user. However, when applying energy conversion technology to human powered equipments, it is important to minimize the increase in extra muscular activity and to maximize the efficiency of human movements. This study proposes a novel energy harvesting methodology that utilizes lateral oscillation of bicycle frame (weaving caused by user weight shifting movements in order to increase the pedaling force in uphill riding or during quick speed-up. Based on the 3D motion analysis, we designed and implemented the prototype of an electro-dynamic energy harvester that can be mounted on the bicycle’s handlebar to collect energy from the side-to-side movement. The harvester was found to generate substantial electric output power of 6.6 mW from normal road riding. It was able to generate power even during uphill riding which has never been shown with other approaches. Moreover, harvesting of energy from weaving motion seems to increase the economy of cycling by helping efficient usage of human power.

    2009-01-01

    A sensing system based on the photoinduced electron transfer of quantum dots (QDs) was designed to measure the interaction of anticancer drug and DNA, taking mitoxantrone (MTX) as a model drug. MTX adsorbed on the surface of QDs can quench the photoluminescence (PL) of QDs through the photoinduced electron-transfer process; and then the addition of DNA will bring the restoration of QDs PL intensity, as DNA can bind with MTX and remove it from QDs. Sensitive detection of MTX with the detection limit of 10 nmol L(-1) and a linear detection range from 10 nmol L(-1) to 4.5 micromol L(-1) was achieved. The dependence of PL intensity on DNA amount was successfully utilized to investigate the interactions between MTX and DNA. Both the binding constants and the sizes of binding site of MTX-DNA interactions were calculated based on the equations deduced for the PL recovery process. The binding constant obtained in our experiment was generally consistent with previous reports. The sensitive and speedy detection of MTX as well as the avoidance of modification or immobilization process made this system suitable and promising in the drug-DNA interaction studies.

    One critical factor for success in characterizing metals polluting mining environments so as to be able to eliminate them and subsequently recover these areas depends upon a speedy and correct response in the analysis of samples. Rapid, simultaneous, multi-element analysis can be undertaken using X-ray fluorescence spectrometry, a versatile, non-destructive analytical technique commonly employed to identify both major and minor elements in samples related to environmental studies. An additional advantage of this technique is the possibility of conducting the analysis directly on solid samples, which is extremely convenient when dealing with environmental samples that are difficult to dissolve, such as soils, sediments and mining wastes. Moreover, in recent years the development of spectrometers equipped with digital-signal processors combined with enlarged X-ray production, using better designs for excitation-detection, has contributed to an improvement in instrumental sensitivity, thus allowing us to detect important polluting elements such as Cd and Pb at trace levels. In this paper the authors describe, on the basis of their own experience, some interesting applications of XRF spectrometry for the analysis of several types of environmental samples related to the study of the dispersion of metals within mining environments: (A) analysis of mining wastes, soils and sediments; (B) analysis of samples of vegetation used as bio indicators or related to phyto remediation studies; and (C) analysis of water samples related to mining operations.

    This paper, for the first time, reported a speedy hyphenated technique of low toxic dual ultrasonic-assisted dispersive liquid-liquid microextraction (dual-UADLLME) coupled with microwave-assisted derivatization (MAD) for the simultaneous determination of 20(S)-protopanaxadiol (PPD) and 20(S)-protopanaxatriol (PPT). The developed method was based on ultra high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) detection using multiple-reaction monitoring (MRM) mode. A mass spectrometry sensitizing reagent, 4'-carboxy-substituted rosamine (CSR) with high reaction activity and ionization efficiency was synthesized and firstly used as derivatization reagent. Parameters of dual-UADLLME, MAD and UHPLC-MS/MS conditions were all optimized in detail. Low toxic brominated solvents were used as extractant instead of traditional chlorinated solvents. Satisfactory linearity, recovery, repeatability, accuracy and precision, absence of matrix effect and extremely low limits of detection (LODs, 0.010 and 0.015ng/mL for PPD and PPT, respectively) were achieved. The main advantages were rapid, sensitive and environmentally friendly, and exhibited high selectivity, accuracy and good matrix effect results. The proposed method was successfully applied to pharmacokinetics of PPD and PPT in rat plasma. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available The fast-food (FF industry and obesity rates have rapidly increased in China. This study examined the FF industry growth in China, key factors contributing to the growth, and the association between FF consumption (FFC and obesity. We collected related data from multiple sources and conducted analysis including linear regression analysis on the increase in FF revenue. It was found that FF industry in China is large, with over two million FF facilities. Its total revenue (in million US$ increased from 10,464 in 1999 to 94,218 in 2013, and by 13% annually since 2008. Increased income, urbanization, busier lifestyle, speedy FF service, assurance of food safety, new brands and foods have stimulated demand for FF. Studies have linked FFC with obesity risk, including a few reporting a positive association between FFC and obesity in China. Rapid expansion of Western-style FF restaurants has also stimulated local FF industry growth. Government regulation and public health education need to address the health consequences of rapidly increasing FFC. Lessons learned in China will help other countries.

    The selective laser melting (SLM) technique is a recent additive manufacturing (AM) technique. Several studies have reported success in the SLM-based production of biocompatible orthopaedic implants and three-dimensional bone defect constructs. In this study, we evaluated the surface properties and biocompatibility of an SLM titanium implant in vitro and compared them with those of a machined (MA) titanium control surface. In addition, we evaluated the osseointegration capability of the SLM implants in vivo and compared it with those of MA and Nobel-speedy (Nobel-S) implants. SLM microtopographical surface analysis revealed porous and high roughness with varied geometry compared with a smooth surface in MA Ti samples but with similar favourable wettability. Osteoblast proliferation and alkaline phosphatase activity were significantly enhanced on the SLM surface. Histological analysis of the bone-implant contact ratio revealed no significant difference among SLM, MA, and Nobel-S implants. Micro-CT assessment indicated that there was no significant difference in bone volume fraction around the implant among SLM implants and other types of surface modification implants. The removal torque value measurement of SLM implants was significantly lower that of than Nobel-S implants P manufacturing technique.

    In Environmental Radioactivity Research Institute, the verification and investigation of the wind velocity field forecast model 'EXPRESS-1' have been carried out since 1991. In fiscal year 1994, as the general analysis, the validity of weather observation data, the local features of wind field, and the validity of the positions of monitoring stations were investigated. The EXPRESS which adopted 500 m mesh so far was improved to 250 m mesh, and the heightening of forecast accuracy was examined, and the comparison with another wind velocity field forecast model 'SPEEDI' was carried out. As the results, there are the places where the correlation with other points of measurement is high and low, and it was found that for the forecast of wind velocity field, by excluding the data of the points with low correlation or installing simplified observation stations to take their data in, the forecast accuracy is improved. The outline of the investigation, the general analysis of weather observation data and the improvements of wind velocity field forecast model and forecast accuracy are reported. (K.I.)

    Full Text Available In this work the Enskog solution of the Boltzmann equation, as corrected by Speedy, together with the Weeks-Chandler-Andersen (WCA perturbation theory of liquids is employed in correlating and predicting self-diffusivities of dense fluids. Afterwards this theory is used to estimate mutual diffusion coefficients of solutes at infinite dilution in sub and supercritical solvents. We have also investigated the behavior of Fick diffusion coefficients in the proximity of a binary vapor-liquid critical point since this subject is of great interest for extraction purposes. The approach presented here, which makes use of a density and temperature dependent hard-sphere diameter, is shown to be excellent for predicting diffusivities in dense pure fluids and fluid mixtures. The calculations involved highly nonideal mixtures as well as systems with high molecular asymmetry. The predicted diffusivities are in good agreement with the experimental data for the pure and binary systems. The methodology proposed here makes only use of pure component information and density of mixtures. The simple algebraic relations are proposed without any binary adjustable parameters and can be readily used for estimating diffusivities in multicomponent mixtures.

    Through the study to improve SPEEDI's capability, a three-dimensional numerical atmospheric model PHYSIC (Prognostic HYdroStatic model Including turbulence Closure model) was developed to apply it to the transport and diffusion evaluation over complex terrains. The detailed description of the atmospheric model was given. This model consists of five prognostic equations; the momentum equations of horizontal components with the so-called Boussinesq and hydrostatic assumptions, the conservation equations of heat, turbulence kinetic energy and turbulence length scale. The coordinate system used is the terrain following z * coordinate system which allows the existence of complex terrain. The minute formula of the turbulence closure calculation, the surface layer process, the ground surface heat budget, and the atmospheric and solar radiation were also presented. The time integration method used in this model is the Alternating Direction Implicit (A.D.I.) method with a vertically and horizontally staggered grid system. The memory storage needed to execute this model with 31 x 31 x 16 grid points, five layers in soil and double precision variables is about 5.3 MBytes. The CPU time is about 2.2 x 10 -5 s per one step per one grid point with a vector processor FACOM VP-100. (author)

    Many compounds submitted for analysis in Chemistry at the University of Southampton do not retain, elute or ionize using open access reversed-phase ultra-high-performance liquid chromatography/mass spectrometry (RP-UHPLC/MS) and require analysis via infusion. An ultra-high-performance supercritical fluid chromatography mass spectrometry approach was implemented to afford high-throughput analysis of these compounds with chromatographic separation. A UPC(2) -TQD MS system has been incorporated into the open access MS provision within Chemistry at the University of Southampton, using an ESCi source (electrospray and atmospheric pressure chemical ionization) and an atmospheric pressure photoionization (APPI) source. Access to instrumentation is enabled via a web-based interface (RemoteAnalyzer™). Compounds such as fluorosugars, fullerenes, phosphoramidites, porphyrins, and rotaxanes exhibiting properties incompatible with RP-UHPLC/MS have been analyzed using automated chromatography and mass spectrometry methods. The speedy return of data enables research in these areas to progress unhindered by sample type. The provision of an electronic web format enables easy incorporation of chromatograms and mass spectra into electronic files and reports. The implementation of UHPSFC/MS increases access to a wide range of chemistries incompatible with reversed-phase chromatography and polar solvents, enabling more than 90% of submitted samples to be analyzed using an open access approach. Further, chromatographic separation is provided where previously flow injection or infusion analyses were the only options. Copyright © 2016 John Wiley & Sons, Ltd.

    Mobile IPv6 (MIPv6) is one of the pioneer standards that support mobility in IPv6 environment. It has been designed to support different types of technologies for providing seamless communications in next generation network. However, MIPv6 and subsequent standards have some limitations due to its handoff latency. In this paper, a fuzzy logic based mechanism is proposed to reduce the handoff latency of MIPv6 for Layer 2 (L2) by scanning the Access Points (APs) while the Mobile Node (MN) is moving among different APs. Handoff latency occurs when the MN switches from one AP to another in L2. Heterogeneous network is considered in this research in order to reduce the delays in L2. Received Signal Strength Indicator (RSSI) and velocity of the MN are considered as the input of fuzzy logic technique. This technique helps the MN to measure optimum signal quality from APs for the speedy mobile node based on fuzzy logic input rules and makes a list of interfaces. A suitable interface from the list of available interfaces can be selected like WiFi, WiMAX or GSM. Simulation results show 55% handoff latency reduction and 50% packet loss improvement in L2 compared to standard to MIPv6.

    The industrial development of nuclear power, especially nuclear power plant technology, in the Federal Republic of Germany has reached a top level position worldwide with respect to availability and safety. The expansion of the use of nuclear power in the Federal Republic of Germany by comparison has been in a paradoxical situation for many years: the importance of this source of energy is being stressed again and again by politicians and industrialists, the speedy development of nuclear power described as indispensable for the national economy and the energy producing utilities. However, in actual practice, industry and the electricity utilities are facing no end of obstacles and difficulties which, ultimately, are beginning to jeopardize the major advantages of nuclear power, at least in the Federal Republic. Special difficulties arise not only in the completion of the prototypes of the two advanced reactor lines, i.e., the fast breeder and the high temperature reactor, but especially also in the completion of the fuel cycle by reprocessing plants, despite the fact that all legal conditions exist for allowing nuclear power to occupy the place found to be necessary also in the Federal Republic of Germany. Industry expects these complex effects on the economy to be recognized and taken into account especially on the political side before this important area of innovation suffers irreparable damage.

    This paper describes the main methods used to speed up the french advanced thermal-hydraulic computer code CATHARE and build a speedy version, called CATHARE-SIMU, adapted to real time calculations and simulation environment. Since CATHARE-SIMU, like CATHARE, uses a numerical scheme based on a fully implicit Newton's iterative method, and therefore with a variable time step, two ways have been explored to reduce the computing time: avoidance of short time steps, and so minimization of the number of iterations per time step, reduction of the computing time needed for an iteration. CATHARE-SIMU uses the same physical laws and correlations as in CATHARE with only some minor simplifications. This was considered the only way to be sure to maintain the level of physical relevance of CATHARE. Finally it is indicated that the validation programme of CATHARE-SIMU includes a set of 33 transient calculations, referring either to CATHARE for two-phase transients, or to measurements on real plants for operational transients

    Wang, Jie; Wang, Jun

    2016-01-01

    In an attempt to improve the forecasting accuracy of crude oil price fluctuations, a new neural network architecture is established in this work which combines Multilayer perception and ERNN (Elman recurrent neural networks) with stochastic time effective function. ERNN is a time-varying predictive control system and is developed with the ability to keep memory of recent events in order to predict future output. The stochastic time effective function represents that the recent information has a stronger effect for the investors than the old information. With the established model the empirical research has a good performance in testing the predictive effects on four different time series indices. Compared to other models, the present model is possible to evaluate data from 1990s to today with extreme accuracy and speedy. The applied CID (complexity invariant distance) analysis and multiscale CID analysis, are provided as the new useful measures to evaluate a better predicting ability of the proposed model than other traditional models. - Highlights: • A new forecasting model is developed by a random Elman recurrent neural network. • The forecasting accuracy of crude oil price fluctuations is improved by the model. • The forecasting results of the proposed model are more accurate than compared models. • Two new distance analysis methods are applied to confirm the predicting results.

    The facilities and nuclear materials under IAEA safeguards have steadily increased in the past few years with consequent increases in the manpower and effort required for the implementation of effective international safeguards. To meet this challenge, various techniques and instruments have been developed with the assistance, support and cooperation of the Member States. Improved NDA equipment now permits accurate verification of plutonium and HEU bearing items; and optical and TV surveillance systems have improved remarkably. Experience in safeguarding nuclear facilities now includes fast-reactor fuel reprocessing and enrichment plants, even though the Hexapartite Safeguards Project is yet to define an agreed approach for safeguarding enrichment plants. The establishment of field offices now enables the IAEA to adequately implement safeguards at important facilities and also with more effective use of manpower. Closer cooperation with Member States via liaison or similar committees makes for effective safeguards implementation and the speedy solution of attendant problems. The technical support programmes from the Member States continue to provide the basis of the recent advances in safeguards techniques and instrumentation. (author)

    In 1989, after only four and a half years of construction, the second unit of the Neckar Joint Nuclear Power Station (GKN-II) was commissioned as the third convoy type nuclear power plant. Its gross power of 1314 MWe makes the pressurized water reactor of GKN-II a unit in the highest power category so far of Siemens/KWU. Delivery to the operators ahead of schedule and observance of the budget are conclusive proof of the advantages of the convoy principle. In addition, GKN-II was able to benefit from the experience accumulated in the construction and commissioning of the two earlier convoy plants. This was reflected in the speedy completion, without major disturbances, of the warranty tests and the trial period of operation. It also has an impact on power operation, the first cycle of which showed the plant to have an availability of 100% throughout and is considered to be a full success by the operators. A special feature of GKN-II is the hybrid cooling tower ensuring that no heated cooling water is returned from the plant into the Neckar river. (orig.) [de

    The nature of clinical research has changed substantially over the last 2 decades, evolving from being centered almost exclusively in developed countries to a more global scenario that is increasingly involving less developed regions of the world. Pharmaceutical companies and some academic cooperative groups have been conducting challenging, large pivotal registration studies with multinational participation. The much more needed globalization of academic research demands particular attention and represents a worthwhile subject for a more profound discussion. The requirement of large sample sizes and the potential for fast recruitment leading to a speedy completion of clinical studies are probably the most important factors that have fueled globalization of studies. Reduced operational costs and the ability to expedite the regulatory approval of drugs in various countries or regions are also important drivers. Globalization of research should be seen as having a much wider effect in the societies involved, in particular, when we consider public health, economic, social, and ethical implications. Most importantly, the process of expanding the network of clinical research sites also fosters the integration and the development of closer relationships among investigators at a global level. We consider this an essential element that should remain a prominent element in the discussion. In this article, we address the underlying reasons for globalization and we highlight some of the scientific and ethical concerns arising as a consequence. Finally, some strategies to address and mitigate the challenges of conducting multinational clinical research are proposed.

    Full Text Available Consumer complaints affect company market value and common sense suggests that a negative impact is expected. However, do complaints always negatively impact company market value? We hypothesize in this study that complaints may have a non-linear effect on market value. Positive (e.g. avoiding high costs to solve complaints and negative (e.g. speedy and intense diffusion tradeoffs may occur given the level of complaints. To test our non-linear hypothesis, a panel data was collected from cell phone service providers from 2005 to 2013. The results supported our tradeoff rationale. Low levels of complaints allow for companies to increase market value, while high levels of complaints cause increasing harm to market value. The sample, model and period considered in this study, indicates a level of 0.49 complaints per thousand consumers as the threshold for a shift in tradeoffs. The effects on market value become increasingly negative when trying to make reductions to move below this level, due to negative tradeoffs.

    Workplace health promotion is a strategy to improve the health and well-being of people at work. The measures aim at the personal, organisational and work environment. Shift work is one of many reasons provoking increased job stress. According to worldwide epidemiological data, up to 30% of the working population are employed in shifts. Taking into consideration that shift work causes a large number of somatic and psychiatric diseases which bear considerable negative consequences for the health status and the quality of life, it seems to be important to initiate health promotion strategies for shift workers in the companies. The results of recent studies indicate that well-scheduled und targeted health programmes can change the lifestyle of shift working employees and have an impact on the risk factors involved. One problem, though, is a considerable time lag till effects become apparent; therefore, the long-term economic effects of workplace health promotion have not been evaluated sufficiently to date. These definitely positive effects highlight the demand for trainings and workshops for people in shift work. We urgently suggest a speedy implementation of the recommended strategies by companies with shift work systems. In our view, this poses a challenge to the "infant" interdisciplinary field of sleep medicine that should be solved.

    hypertensive retinopathy (HR) in the retina of the eye is disturbance caused by high blood pressure disease, where there is a systemic change of arterial in the blood vessels of the retina. Most heart attacks occur in patients caused by high blood pressure symptoms of undiagnosed. Hypertensive retinopathy Symptoms such as arteriolar narrowing, retinal haemorrhage and cotton wool spots. Based on this reasons, the early diagnosis of the symptoms of hypertensive retinopathy is very urgent to aim the prevention and treatment more accurate. This research aims to develop a system for early detection of hypertension retinopathy stage. The proposed method is to determine the combined features artery and vein diameter ratio (AVR) as well as changes position with Optic Disk (OD) in retinal images to review the classification of hypertensive retinopathy using Deep Neural Networks (DNN) and Boltzmann Machines approach. We choose this approach of because based on previous research DNN models were more accurate in the image pattern recognition, whereas Boltzmann machines selected because It requires speedy iteration in the process of learning neural network. The expected results from this research are designed a prototype system early detection of hypertensive retinopathy stage and analysed the effectiveness and accuracy of the proposed methods.

    2012-01-01

    Full Text Available Periodic outbreaks of epizooties of foot-and-mouth disease in countries of the Middle East and Africa pose a serious health threat to European states, in particular countries of the Mediterranean region and the Balkan peninsula. There are multiple reasons for the frequent appearance of this disease in Africa and the territory of the Middle East, and they are all a consequence of the insufficient development of the states in these geographic regions. More precisely, epizooties of foot-and-mouth disease are difficult to control in these regions due to the limited possibilities for activities by veterinary services, insufficiently developed diagnostic capacities for speedy and precise laboratory diagnostics, the lack of more advanced knowledge among the village populations, and the traditional manner of breeding ruminants. As a result of intensive traffic in goods, services and people, the cultural and tourist links between the Middle East and European countries, there is a constant and real danger of a swift and uncontrolled spreading of foot-and-mouth disease to the territory of Europe. This is why it is a priority of epizootiological services of the majority of European countries constantly to monitor the epizootiological situation in the Middle East and in Africa.

    2015-10-01

    A large international literature on how lay citizens make sense of various aspects of science and technology has been generated by investigations which utilise small group methods. Within that literature, focus group and other group-based methods have come to co-exist, and to some extent, hybridise, with the use of small groups in citizen engagement initiatives. In this article, we report on how we drew upon these methodological developments in the design and operationalisation of a policymaking support tool (STAVE). This tool has been developed to gain insight, in a relatively speedy and cost-effective way, into practical details of the everyday lived experience of people's lives, as relating to the sustainability of corresponding practices. An important challenge we faced was how, in Kuhn's terms, to 'translate' between the forms of life corresponding to the world of policymaking and the world of everyday domestic life. We examine conceptual and methodological aspects of how the tool was designed and assembled, and then trialled in the context of active real-world collaborations with policymaking organisations. These trials were implemented in six European countries, where they were used to support work on live policy issues concerned with sustainable consumption. © The Author(s) 2014.

    A new gamma-ray counting and data processing system for non-destructive neutron activation analysis has been set up in Radioisotope Center in Nagoya University. The system carry out gamma-ray counting, sample change and data processing automatically, and is able to keep us away from parts of complicated operations in INAA. In this study, we have arranged simple analytical procedure that makes practical works easier than previous. The concrete flow is described from the reparation of powder rock samples to gamma-ray counting and data processing by the new INAA system. Then it is run over that the analyses used two Geological Survey of Japan rock reference samples JB-1a and JG-1a in order to evaluate how the new analytical procedure give any speediness and accuracy for analyses of geological materials. Two United States Geological Survey reference samples BCR-1 and G-2 used as the standard respectively. Twenty two elements for JB-1a and 25 elements for JG-1a were analyzed, the uncertainty are <5% for Na, Sc, Fe, Co, La, Ce, Sm, Eu, Yb, Lu, Hf, Ta and Th, and of <10% for Cr, Zn, Cs, Ba, Nd, Tb and U. This system will enable us to analyze more than 1500 geologic samples per year. (author)

    2005-01-01

    Whenever a process is disturbed either by servo system or regulatory system, the control action is applied to trace the desired point. An efficient controller setting should be selected in order to get speedy response under the pattern or constraints of quality of the product. The effective control action is desired to utilize the maximum of raw material and to minimize the waste. This is a critical problem in cases where the raw material or product is valuable and costly, e.g. pharmaceuticals. This problem has been addressed in this work on a laboratory scale plant. The plant consists of feed tank, pumps, plate and frame heat exchanger and hot water re-circulator tank. The system responses were logged with computer while the controller was tuned with Ziegler-Nichols (Z-N) and Cohen-Coon (C-C) tunings. A detailed study indicates that Ziegler-Nichols Controller tunings is better than Cohen-Coon as waste production was minimized. (author)

    Full Text Available Cities in developing countries are faced waste management challenges in terms of quantity and quality. Most of the time, solid and liquid wastes are dumped on street and open spaces. Uncontrolled waste dumped has led to diverse kind of health problems. The purpose of this article is to characterize urban cities and evaluate their waste generation using the Geographical Info rmation System (GIS. The focus is on two cities in Burkina Faso. Specific variabl es which were considered during the survey include urban fabric, grey water outlets a nd household garbage dumps sites/techniques. The study shows that in the two cities, the most dominant urban fabric is low standard of living (about 64% of housing in Fada and 62% of housing in Pouytenga. The urban fabric is also characterized by the exis tence of empty spaces. Overall, the average density of grey water discharge points is 0.85 points and 5.7 points per ha of street in Fada N’Gourma and Pouytenga respectivel y. The average density of solid waste dumps is 1.45 waste dumps per ha street a nd 7 waste dumps per ha street in Fada N'Gourma and Pouytenga respectively. In case of urgent waste management intervention, the priority areas for speedy intervention are area 10 in Fada N’Gourma, areas 2 and 5 in Pouytenga. GIS applied to w aste management can be a decision making tool for urban planne rs in developing country.

    5-Fluorouracil (5-FU) and its oral pro-drug capecitabine are widely used in oncology for the treatment of various solid tumours, including colorectal cancers. Cardiotoxicity to these drugs is not an uncommon adverse effect and has been reported in 1%–18% of patients. Capecitabine has been reported to trigger mid-apical Takotsubo syndrome (TS). We describe here the case of a 55-year-old man who presented with cardiogenic shock and ECG signs of ST-elevation myocardial infarction. The symptoms began 28 h after the commencement of capecitabine adjuvant therapy, following a radical right-sided hemicolectomy for low-differentiated adenocarcinoma of the caecum. Echocardiography showed severe global left ventricular dysfunction. Cardiac magnetic resonance imaging showed no signs of late gadolinium enhancement. These clinical, cardiac image study findings and the course of the disease with full recovery within one week were consistent with global TS triggered by the adjuvant therapy capecitabine and presenting with a life-threatening cardiogenic shock. Moreover, we have demonstrated the speedy dynamic of the left ventricular wall motion abnormality with global TS at presentation and basal (inverted) TS findings 4 days later on.

    Recent years have brought new challenges for a clinician engaged in treatment of lung cancer. Advances in immunotherapy in the treatment of melanoma lead to increase of the number of studies in immunotherapy of other tumors. At present we are confronted with the fact that new drugs have been approved for immunotherapy of NSCLC. We feel a strong need for a speedy familiarization with the knowledge in this field both in terms of at least a basic understanding of the mechanisms of functioning of the immune system, and the new paradigms of treatment especially in the context of the assessment of response to treatment, which are significantly different from what we were used to in chemotherapy. This paper is designed as the first information for the clinician confronted with the possibility to use immunotherapy in the treatment of lung cancer. In the situation where new paradigms are only at the stage of initial formulations and the „dust has not settled yet“ we certainly did not avoid simplistic and non-rigorous formulations. Many things are likely to be modified in the near future. Nevertheless, we hope that the information we have attempted to summarize here may be useful for practicing clinician. (author)

    To explore an efficient, safe, and speedy application of pulsed electric field (PEF) technology for enzymatic modification, effects of PEF treatment on the enzymatic activity, property and kinetic parameters of α-amylase were investigated. Conformational transitions were also studied with the aid of circular dichroism (CD) and fluorescence spectra. The maximum enzymatic activity of α-amylase was obtained under 15 kV/cm electric field intensity and 100 mL/min flow velocity PEF treatment, in which the enzymatic activity increased by 22.13 ± 1.14% compared with control. The activation effect could last for 18 h at 4 °C. PEF treatment could widen the range of optimum temperature for α-amylase, however, it barely exerted any effect on the optimum pH. On the other hand, α-amylase treated by PEF showed an increase of Vmax, t1/2 and ΔG, whereas a decrease of Km and k were observed. Furthermore, it can be observed from fluorescence and CD spectra that PEF treatment had increased the number of amino acid residues, especially that of tryptophan, on α-amylase surface with enhanced α-helices by 34.76% and decreased random coil by 12.04% on α-amylase when compared with that of untreated. These changes in structure had positive effect on enhancing α-amylase activity and property.

    Sasol coal has developed a better brick for construction of ventilation walls underground. It has proven to be a speedy and cost-saving alternative to the standard concrete block used for the purpose. The brick has an interlocking design ensuring that it is laid correctly. Unlike the conventional concrete block, the ventilation walls built for the new brick do not have to be plastered to achieve airtightness. The skills required to build such walls are minimal as the design of the brick makes it virtually impossible to lay it badly or unevenly - further facilitated by the absence of mortar. While introducing the new method Sasol Coal took the opportunity to introduce a purpose-made trailer for transporting the bricks, with the trailer doubling as a building platform on site. This has further contributed to the efficiency and speed of the operation. It has also reduced to a minimum the number of times the bricks are handled, thus cutting down on breakages. 1 fig.

  18. Gaps, tensions, and conflicts in the FDA approval process: implications for clinical practice.

    Deyo, Richard A

    2004-01-01

    Despite many successes, drug approval at the Food and Drug Administration (FDA) is subject to gaps, internal tensions, and conflicts of interest. Recalls of drugs and devices and studies demonstrating advantages of older drugs over newer ones highlight the importance of these limitations. The FDA does not compare competing drugs and rarely requires tests of clinical efficacy for new devices. It does not review advertisements before use, assess cost-effectiveness, or regulate surgery (except for devices). Many believe postmarketing surveillance of drugs and devices is inadequate. A source of tension within the agency is pressure for speedy approvals. This may have resulted in "burn-out" among medical officers and has prompted criticism that safety is ignored. Others argue, however, that the agency is unnecessarily slow and bureaucratic. Recent reports identify conflicts of interest (stock ownership, consulting fees, research grants) among some members of the FDA's advisory committees. FDA review serves a critical function, but physicians should be aware that new drugs may not be as effective as old ones; that new drugs are likely to have undiscovered side effects at the time of marketing; that direct-to-consumer ads are sometimes misleading; that new devices generally have less rigorous evidence of efficacy than new drugs; and that value for money is not considered in approval.

    For over 20 years complex, in-reactor experiments have been performed at Argonne National Laboratory (ANL) to investigate the performance of nuclear reactor fuel and to support the development of large computer codes that address questions of reactor safety in full-scale plants. Not only are computer codes an important end-product of the research, but computer analysis is also involved intimately at most stages of experiment planning, data reduction, and evaluation. For instance, many experiments are of sufficiently long duration or, if they are of brief duration, occur in such a purposeful sequence that need for speedy availability of on-line data is paramount. This is made possible most efficiently by computer assisted displays and evaluation. A purposeful linking of main-frame, mini, and micro computers has been effected over the past eight years which greatly enhances the speed with which experimental data are reduced to useful forms and applied to the relevant technological issues. This greater efficiency in data management led also to improvements in the planning and execution of subsequent experiments. Raw data from experiments performed at INEL is stored directly on disk and tape with the aid of minicomputers. Either during or shortly after an experiment, data may be transferred, via a direct link, to the Illinois offices of ANL where the data base is stored on a minicomputer system. This Idaho-to-Illinois link has both enhanced experiment performance and allowed rapid dissemination of results

    The fast-food (FF) industry and obesity rates have rapidly increased in China. This study examined the FF industry growth in China, key factors contributing to the growth, and the association between FF consumption (FFC) and obesity. We collected related data from multiple sources and conducted analysis including linear regression analysis on the increase in FF revenue. It was found that FF industry in China is large, with over two million FF facilities. Its total revenue (in million US$) increased from 10,464 in 1999 to 94,218 in 2013, and by 13% annually since 2008. Increased income, urbanization, busier lifestyle, speedy FF service, assurance of food safety, new brands and foods have stimulated demand for FF. Studies have linked FFC with obesity risk, including a few reporting a positive association between FFC and obesity in China. Rapid expansion of Western-style FF restaurants has also stimulated local FF industry growth. Government regulation and public health education need to address the health consequences of rapidly increasing FFC. Lessons learned in China will help other countries.

  1. The Velocity of Density: Can We Build More Sustainable Cities Fast Enough?

    Directory of Open Access Journals (Sweden)

    Markus Moos

    2017-12-01

    Full Text Available Urban planners now commonly advocate for increases in density of the built environment to reduce car dependence and enhance the sustainability of cities. The analysis in this paper asks about the speed at which density as a sustainability policy can be implemented. The Greater Toronto Hamilton Area (GTHA is used as a case study to measure how quickly existing areas could be densified to meet minimum transit supportive density thresholds. Almost 70% of existing residents live in neighborhoods with densities below minimum transit supportive densities. The findings show that increases in minimum densities could be attained roughly within the target time horizon of existing growth plans, but that these increases hinge on assumptions of continuing high growth rates. The sustainability of cities relies on a high ‘velocity of density’, a term proposed in the paper to refer to the speed at which density can be implemented. Density is often slowed or halted by local residents, which could prove problematic if sustainability objectives require speedy implementation, for instance to address climate change. Analysis of the velocity of density suggests that planning for sustainability, and climate change, in cities would benefit from considering a broader set of solutions to car dependence in existing low-density areas than changes to the density of the built form alone.

    Full Text Available One of the greatest battles of the Great Patriotic and also the World War II took place on the outskirts of the capital of Nazi Germany on April 16, 1945. Three magor fronts - 1st Belorussian, 2nd Byelorussian, 1st Ukrainian - and four tank armies were involved. They were not used as highly mobile groups to enter Berlin from the north and north-west, they were sent first to break powerful enemy defenses, and then to wage battles on the streets. The Supreme Command and the commanders of the 1st Byelorussian and 1st Ukrainian fronts understood the inevitability of heavy losses in tanks and troops, but deliberately took this step. The aim was not only a speedy capture of the German capital and the end of the war, but also to be ahead of allies on their way to Berlin. The article deals with the planning and preparation for the Berlin Strategic Offensive Operation, the use of 2nd Guards Tank Army, who played along with other tank divisions a magor role in the success of this operation.

    The energy and fuel obtaining process must be understand as a political concept and a socially built one. Such a process should be understood taking in account social impacts, environmental issues, land struggles. There are plenty of empirical examples able to identify flows, directions and speedy up enterprises when extracting matter and energy conversion within areas of high social and environmental sensibility. The infra-structure expansion over traditional people areas, high biodiversity mapped regions and environmental sensibility areas are expression of the capital intensive accumulation process and must be legitimated in one way or another. Simultaneously two way processes occur: in one hand the use of land, riverside areas and natural landscapes to generate electrical energy and fuel obtaining an in the other hand the abandon of original usage for the land. Specifically, in the Amazon rain forest area it is evident that the mentioned flows are supported by the natural wealthy. So, the analyses under a scientific approach, elaborating theories, demonstrations and occurrences documentation are necessary. Two preliminary expectations are posted by the article: 1) Discuss the implications due to the creation of energetic reserve areas over traditional people regions; 2) Produce a preliminary picture of demands over natural resources and respective social conflicts based on significant selected cases.

    Sinclair, M.H.

    1979-01-01

    This paper discusses and illustrates the complicated problems faced by the plastic surgeon in a cancer hospital. His patients are often weakened, both physically and psychologically, not only by the cancer itself, but also by extensive ablative surgery. The goal of the plastic surgeon is rehabilitation of the patient after he is cured of cancer. Good planning with the cancer surgeon before the ablative operation is very important, as is immediate repair, whenever possible. The simplest procedure with the fewest stages that can accomplish satisfactory repair in the shortest time should be chosen, as we can never, even after the most extensive cancer operation, be sure that no recurrence will appear. Partial surgical repair and the use of a prosthesis should be considered for complicated defects in old and weak patients. Postoperative radiation therapy, if indicated, can be given after the flap has healed into the defect but before the pedicle is separated. The plastic surgeon should always be aware that his most important goal is speedy and satisfactory rehabilitation of the patient

    Full Text Available The Beijing 2008 Olympic and Paralympic Sailing Competitions (referred to as OPSC hereafter were held at Qingdao during August 9–23 and September 7–13 2008, respectively. The Qingdao Meteorological Bureau was the official provider of weather support for the OPSC. Three-dimensional real-time information with high spatial-temporal resolution was obtained by the comprehensive observation system during the OPSC, which included weather radars, wind profile radars, buoys, automated weather stations, and other conventional observations. The refined forecasting system based on MM5, WRF, and statistical modules provided point-specific hourly wind forecasts for the five venues, and the severe weather monitoring and forecasting system was used in short-term forecasts and nowcasts for rainstorms, gales, and hailstones. Moreover, latest forecasting products, warnings, and weather information were communicated conveniently and timely through a synthetic, speedy, and digitalized network system to different customers. Daily weather information briefings, notice boards, websites, and community short messages were the main approaches for regatta organizers, athletes, and coaches to receive weather service products at 8:00 PM of each day and whenever new updates were available. During the period of OPSC, almost one hundred people were involved in the weather service with innovative service concept, and the weather support was found to be successful and helpful to the OPSC.

    Full Text Available The determination of the optimal circular path has become widely known for its difficulty in producing a solution and for the numerous applications in the scope of organization and management of passenger and freight transport. It is a mathematical combinatorial optimization problem for which several deterministic and heuristic models have been developed in recent years, applicable to route organization issues, passenger and freight transport, storage and distribution of goods, waste collection, supply and control of terminals, as well as human resource management. Scope of the present paper is the development, with the use of fuzzy sets, of a practical, comprehensible and speedy heuristic algorithm for the improvement of the ability of the classical deterministic algorithms to identify optimum, symmetrical or non-symmetrical, circular route. The proposed fuzzy heuristic algorithm is compared to the corresponding deterministic ones, with regard to the deviation of the proposed solution from the best known solution and the complexity of the calculations needed to obtain this solution. It is shown that the use of fuzzy sets reduced up to 35% the deviation of the solution identified by the classical deterministic algorithms from the best known solution.

    Full Text Available We quantified insect visitation rates by counting how many flowers/inflorescences were probed per unit time for five plant species (four native and one garden: California lilac, bramble, ragwort, wild marjoram, and ivy growing in Sussex, United Kingdom, by following individual insects (n=2987 from nine functional groups (honey bees (Apis mellifera, bumble bees (Bombus spp., hoverflies, flies, butterflies, beetles, wasps, non-Apidae bees, and moths. Additionally, we made a census of the insect diversity on the studied plant species. Overall we found that insect groups differed greatly in their rate of flower visits (P<2.2e-16, with bumble bees and honey bees visiting significantly more flowers per time (11.5 and 9.2 flowers/minute, resp. than the other insect groups. Additionally, we report on a within-group difference in the non-Apidae bees, where the genus Osmia, which is often suggested as an alternative to honey bees as a managed pollinator, was very speedy (13.4 flowers/minute compared to the other non-Apidae bees (4.3 flowers/minute. Our census showed that the plants attracted a range of insects, with the honey bee as the most abundant visitor (34%. Therefore, rate differences cannot be explained by particular specializations. Lastly, we discuss potential implications of our conclusions for pollination.

    TO-2 is a fish cell line derived from the Tilapia ovary. It grows over a wide range of temperature (15-34 0 C). We report the effects of temperature on DNA replication and u.v. repair in TO-2 cells. When the cells were moved from 31 0 C to the sublethal high temperature of 37 0 C, the rate of DNA synthesis first decreased to 60%, then speedy recovery soon set in, and after 8h at 37 0 C the rate of DNA synthesis overshot the 31 0 C control level by 180%. When moved to low temperature (18 0 C) Tilapia cells also showed an initial suppression of DNA synthesis before settling at 30% of the control level. U.V. reduced but could not block DNA synthesis completely. The inhibition was overcome in 3h at 37, 31 and 25 0 C, but not at 18 0 C. Initiation of nascent DNA synthesis was blocked at 4Jm -2 in TO-2 cells compared with ≤ 1Jm -2 in mammalian cells. After 9Jm -2 u.v. irradiation, low molecular weight DNA replication intermediates started to accumulate. TO-2 cells showed low levels of u.v.-induced excision repair. (author)

  9. THE PROBLEM OF REVERSION OF OKINAWA IN THE US-JAPAN POSTWAR RELATIONS

    Full Text Available In the postwar period the Okinawa problem for many years was a stumbling block in the relations between Japan and the United States, creating the risk of undermining the foundations of the alliance. In fact, Okinawa personified a deep contradiction between the diplomatic and military-strategic interests of the United States in East Asia and the national interests of Japan, for which Okinawa was a primarily domestic political problem. In the mid-1960 's, despite the increasing role of Okinawa in the American global strategy after the start of the Vietnam war, the United States came to the conclusion of the speedy reversion of Okinawa to Japan. The main obstacle for the implementation of this decision was the nuclear weapon stored in Okinawa, which played an important role in the global strategy of Pentagon. The United States managed to find an option of reversion Okinawa to Japan in 1972, under which they retained the right to store nuclear weapons in Okinawa and to transit them through the island in the case of emergency. The transfer administrative right on Okinawa to Japan was a symbolic act, by which the United States demonstrated their willingness for Japan to play a ‘responsible role’ in the alliance as an active actor, not just a junior partner.

    A relational database (RDB) has been developed for classifying TJ-II experimental data according to physical criteria. Two objectives have been achieved: the design and the implementation of the database and the software tools for data access depending on a single software driver. TJ-II data were arranged in several tables with a flexible design, speedy performance, efficient search capacity and adaptability to meet present and future, requirements. The software has been developed to allow the access to the TJ-II RDB from a variety of computer platforms (ALPHA AXP/True64 UNIX, CRAY/UNICOS, Intel Linux, Sparc/Solaris and Intel/Windows 95/98/NT) and programming languages (FORTRAN and C/C++). The database resides in a Windows NT Server computer and is managed by Microsoft SQL Server. The access software is based on open network computing remote procedure call and follows client/server model. A server program running in the Windows NT computer controls data access. Operations on the database (through a local ODBC connection) are performed according to predefined permission protocols. A client library providing a set of basic functions for data integration and retrieval has been built in both static and dynamic link versions. The dynamic version is essential in accessing RDB data from 4GL environments (IDL and PV-WAVE among others)

    Combat stress reaction (CR) is a syndrome with a wide range of symptoms including changes in soldiers' behaviors, emotional and physiological responses, avoidance and a decrease in both personal and military functioning. The short-term goal in treating CR is a speedy return to healthy functioning, whereas the long-term goal is to prevent the development of PTSD. Previous research has indicated that the achievement of this short-term goal affects the achievement of the long-term goal and vice versa. Effective treatment requires intervention by trained professionals proficient in reinforcing personal and functional identity without psychiatric labelling. The present paper presents a therapeutic model integrating OT in treating CR within a military setting. The model emphasizes the importance of preventing fixation to the role of 'patient' and a rapid return to maximal functioning. Based on Kielhofner's Model of Human Occupation, which aims to promote adaptive and efficient functioning by engaging soldiers in tasks supporting their military identity, empowering functionality, and increasing their perceived competency. The model emphasizes the therapeutic milieu within a military environment. Practical application of this model focuses on interdisciplinary aspects and client-focused application. The paper describes an assessment process for each soldier entering the CR unit and a treatment model integrating OT.

    As the angiography in the field of radiological sciences is being increasingly diversified in its techniques, clinical applications of interventional radiology are rapidly increasing not only for its usefulness in simple diagnosis but for its capabilities of affording, by means of radiological surveillance, biological data such as those concerning tissues which are even substitutionary or supplementary to treatment of diseases. During the last 5 years from July 1980 to 1984 such applications in the cardiovascular division showed a trend of radical increase and thus emerging as a new domain of radiological medicine which has vast influence on diagnosis and treatment. The present treatise presents the results of research performed on the following: 1) Need for close coordination among physicians, radiologists, and nurses in the radiology department. 2) Need for prior explanation to the patient of the procedure to be followed to relieve his anxiety. 3) Checking of the angiographic equipment and selection of technical factors. 4) Proper management of manpower including medical radiologists and assistant radiologists. 5) Sterilization of auxiliary equipment required for surgical operation. 6) Selection of a catheter and control of clinical materials such as contrast agents. 7) Supplementary arrangements for speedy performance of clinical services.

    Full Text Available I wonder why sometimes we are able to rapidly recognize patterns of disease presentation, formulate a speedy diagnostic closure, and go on with a treatment plan. On the other hand sometimes we proceed studing in deep our patient in an analytic, slow and rational way of decison making. Why decisions sometimes can be intuitive, while sometimes we have to proceed in a rigorous way? What is the “back ground noise” and the “signal to noise ratio” of presenting sintoms? What is the risk in premature labeling or “closure” of a patient? When is it useful the “cook-book” approach in clinical decision making? The Emergency Department is a natural laboratory for the study of error” stated an author. Many studies have focused on the occurrence of errors in medicine, and in hospital practice, but the ED with his unique operating characteristics seems to be a uniquely errorprone environment. That's why it is useful to understand the underlying pattern of thinking that can lead us to misdiagnosis. The general knowledge of thought processes gives the psysician awareness an the ability to apply different tecniques in clinical decision making and to recognize and avoid pitfalls.

    Full Text Available Engineered TAL-effector nucleases (TALENs and TALE-based constructs have become powerful tools for eukaryotic genome editing. Although many methods have been reported, it remains a challenge for the assembly of designer-based TALE repeats in a fast, precise and cost-effective manner. We present an ULtiMATE (USER-based Ligation Mediated Assembly of TAL Effector system for speedy and accurate assembly of customized TALE constructs. This method takes advantage of uracil-specific excision reagent (USER to create multiple distinct sticky ends between any neighboring DNA fragments for specific ligation. With pre-assembled templates, multiple TALE DNA-binding domains could be efficiently assembled in order within hours with minimal manual operation. This system has been demonstrated to produce both functional TALENs for effective gene knockout and TALE-mediated gene-specific transcription activation (TALE-TA. The feature of both ease-of-operation and high efficiency of ULtiMATE system makes it not only an ideal method for biologic labs, but also an approach well suited for large-scale assembly of TALENs and any other TALE-based constructions.

    Sovereign Wealth Funds (SWF) have different titles, goals and rules, but they share the underlying objective of helping governments deal with the problems created by large and variable revenues (mainly from energy or other commodity related sectors). In Kazakhstan, such a fund (the National Fund of the Republic of Kazakhstan (NFRK)) was established in 2000. This fund operates as both a stabilisation and a savings fund. The first test for the NFRK was 2007-2009 financial crisis, where the NFRK 'saved' the economy and guarantied its speedy recovery. The paper analyses the NFRK's operation up to 2007 and during the crisis years 2007-9, before drawing conclusions and implications for the future. Between 2001 and 2007 the NFRK conservatively accumulated assets, which proved to be useful in limiting the impact of the post-2007 crisis. However, the pre-2007 experience indicated structural weaknesses associated with discretionary executive authority and non-transparency. The paper concludes by observing that this history has created significant challenges for the future. - Highlights: → Expenditures of resource revenues should be consistent with the government's long-term plan to save for the future. → A system of indicators for the non-resource deficit is required. → Domestic investment provides more stability and economic resilience. → A transparent and accountable governance structure of the NFRK is required.

    2015-08-01

    The recent onslaught of mass spectrometry (MS) to measurements of steroid hormones, including demands that they should be the only acceptable method, has confused clinicians and scientists who have relied for more than 40 years on a variety of immunoassay (IA) methods in steroid hormone measurements. There is little doubt that MS methods with their superior specificity will be the future method of choice in many clinical and research applications of steroid hormone measurement. However, the majority of steroid measurements are currently, and will continue to be, carried out using various types of IAs for several reasons, including their technical ease, cost and availability of commercial reagents. Speedy replacement of all IAs with MS is an unrealistic and unnecessary goal, because the availability of MS measurements is limited by cost, need of expensive equipment, technical demands and lack of commercial applications. Furthermore, IAs have multiple well-known advantages that vindicate their continuing use. The purpose of this article is to elucidate the advantages and limitations of the MS and IA techniques from two angles, i.e. promotion of MS and defence of IA. The purpose of the text is to give the reader an unbiased view about the current state and future trends of steroid analysis and to help him/her choose the correct assay method to serve his/her diagnostic and research needs. © 2015 European Society of Endocrinology.

    Chemical and biological warfare agents (CBWA's) are diverse in nature; volatile acute low-molecular-weight toxic compounds, chemical warfare agents (CWA's, gaseous choking and blood agents, volatile nerve gases and blister agents, nonvolatile vomit agents and lacrymators), biological toxins (nonvolatile low-molecular-weight toxins, proteinous toxins) and microbes (bacteria, viruses, rickettsiae). In the consequence management against chemical and biological terrorism, speedy decontamination of victims, facilities and equipment is required for the minimization of the damage. In the present situation, washing victims and contaminated materials with large volumes of water is the basic way, and additionally hypochlorite salt solution is used for decomposition of CWA's. However, it still remains unsolved how to dispose large volumes of waste water, and the decontamination reagents have serious limitation of high toxicity, despoiling nature against the environments, long finishing time and non-durability in effective decontamination. Namely, the existing decontamination system is not effective, nonspecifically affecting the surrounding non-target materials. Therefore, it is the urgent matter to build up the usable decontamination system surpassing the present technologies. The symposiast presents the on-going joint project of research and development of the novel decontamination system against CBWA's, in the purpose of realizing nontoxic, fast, specific, effective and economical terrorism on-site decontamination. The projects consists of (1) establishment of the decontamination evaluation methods and verification of the existing technologies and adaptation of bacterial organophosphorus hydrolase, (2) development of adsorptive elimination technologies using molecular recognition tools, and (4) development of deactivation technologies using photocatalysis.

    The study of 422 non-01 Vibrio cholerae strains from nine provinces, 9 of them isolated from a water-borne disease outbreak, was performed. All the strains exhibited antimicrobial susceptibility and virulence factors. The nine strains from the outbreak were subjected to a DNA macrorestriction study based on the pulsed field electrophoresis technique. For the first time in Cuba and the Caribbean. The circulation of atypical non-01 V cholerae strains (resistent to vibriostatic compound 0129 and trimethoprim/sulfamethoxazole). The behavior of antimicrobial susceptibility evinced for the first time the circulation of two different resistence patterns in Cuba (ampicilline, trimethoprim/ sulfamethoxazole, sulfonamide and tetracycline, trimethoprim/ sulfamethoxazole, sulfonamide). The frequency of trimethoprim/ sulfamethoxazole-resistent strains was similar during the whole period of study. However, resistance to ampicilline decreased whereas resistance to tetracycline increased. The main found virulence factors were gelatinase, hemolysine, elastase and adherence to Hep-2 cells. On the other hand, the outbreak strains showed higher percentages than the others due to the presence of heat-liable toxin and fimbriae. The results of the molecular and epidemiological studies allowed giving a speedy and accurate response that explained the etiology of the first food-borne disease outbreak.

    Diabetic patients suffer a high rate of amputation. There are two main reasons; infection which can spread rapidly leading to overwhelming tissue destruction and severe peripheral arterial disease. Studies that have stratified patients according to the presence or absence of both peripheral arterial disease and infection have shown significantly worse outcomes in patients with both peripheral arterial disease and infection. There have been two crucial significant advances in diabetic foot care to improve the outlook of these diabetic patients. First, there has been the realisation that diabetic foot patients experience repeated crises from the rapid onset infection and need a special form of easily accessible care within a multidisciplinary diabetic foot service to provide prompt treatment of infection before it progresses to necrosis. Secondly, within such a service, prompt diagnosis of ischaemia and urgent revascularisation has been established as a further important aspect of successful management. The critical factor in saving limbs is making a rapid diagnosis of infection and ischaemia and administering the appropriate treatment early. In this way speedy healing can be achieved and this can prevent patients from needing amputations.

    Services composition is fundamental to software development in multi-service wireless sensor networks (WSNs). The quality of service (QoS) of services composition applications (SCAs) are confronted with severe challenges due to the open, dynamic, and complex natures of WSNs. Most previous research separated various QoS indices into different fields and studied them individually due to the computational complexity. This approach ignores the mutual influence between these QoS indices, and leads to a non-comprehensive and inaccurate analysis result. The universal generating function (UGF) shows the speediness and precision in QoS analysis. However, only one QoS index at a time can be analyzed by the classic UGF. In order to efficiently analyze the comprehensive QoS of SCAs, this paper proposes an improved UGF technique-vector universal generating function (VUGF)-which considers the relationship between multiple QoS indices, including security, and can simultaneously analyze multiple QoS indices. The numerical examples demonstrate that it can be used for the evaluation of the comprehensive QoS of SCAs subjected to the security constraint in WSNs. Therefore, it can be effectively applied to the optimal design of multi-service WSNs.

    Measurement-while-drilling (MWD) aims at collecting accurate, speedy and high resolution information from the production blast hole drills with a target of characterization of highly variable rock masses encountered in sub-surface excavations. The essence of the technique rests on combining the physical drill variables in a manner to yield a fairly accurate description of the sub-surface rock mass much ahead of following downstream operations. In this light, the current paper presents an overview of the MWD by explaining the technique and its set-up, the existing drill-rock mass relationships and numerous on-going researches highlighting the real-time applications. Although the paper acknowledges the importance of concepts of specific energy, rock quality index and a couple of other indices and techniques for rock mass characterization, it must be distinctly borne in mind that the technique of MWD is highly site-specific, which entails derivation of site-specific calibration with utmost care.

  7. The art of designing markets.

    2007-10-01

    Traditionally, markets have been viewed as simply the confluence of supply and demand. But to function properly, they must be able to attract a sufficient number of buyers and sellers, induce participants to make their preferences clear, and overcome congestion by providing both enough time to make choices and a speedy means of registering them. Solutions to these challenges are the province of market design--a blend of game theory and experimental economics. Roth, a professor of both business and economics at Harvard, is a leading market designer. He and his colleagues have rescued failing markets by, for example, designing labor clearinghouses through which U.S. doctors get their first jobs and auctions through which the Federal Communications Commission sells licenses for parts of the radio broadcast spectrum. They have also created marketlike allocation procedures that involve neither prices nor an exchange of money; these include systems for assigning children to schools in Boston and New York and for facilitating exchanges of kidneys. Computers enable the design of "smart markets" that combine the inputs of users in complex ways: In kidney exchange, they run through every possible match of donors and recipients to arrange the greatest possible number of transplants. In the future, computers may make it possible to auction bundled goods, such as airport takeoff and landing slots. As online markets--like those for jobs and dating--proliferate, a growing understanding of markets in general will provide virtually limitless opportunities for market design.

    Dendrobium is a commonly used and precious herb in Traditional Chinese Medicine. The high biodiversity of Dendrobium and the therapeutic needs require tools for the correct and fast discrimination of different Dendrobium species. This study investigates Fourier transform infrared spectroscopy followed by cluster analysis for discrimination and chemical phylogenetic study of seven Dendrobium species. Despite the general pattern of the IR spectra, different intensities, shapes, peak positions were found in the IR spectra of these samples, especially in the range of 1800-800 cm-1. The second derivative transformation and alcoholic extracting procedure obviously enlarged the tiny spectral differences among these samples. The results indicated each Dendrobium species had a characteristic IR spectra profile, which could be used to discriminate them. The similarity coefficients among the samples were analyzed based on their second derivative IR spectra, which ranged from 0.7632 to 0.9700, among the seven Dendrobium species, and from 0.5163 to 0.9615, among the ethanol extracts. A dendrogram was constructed based on cluster analysis the IR spectra for studying the chemical phylogenetic relationships among the samples. The results indicated that D. denneanum and D. crepidatum could be the alternative resources to substitute D. chrysotoxum, D. officinale and D. nobile which were officially recorded in Chinese Pharmacopoeia. In conclusion, with the advantages of high resolution, speediness and convenience, the experimental approach can successfully discriminate and construct the chemical phylogenetic relationships of the seven Dendrobium species.

Dismantling of bridge within time schedule in densely populated area requires controlled and pre-planned blasting methodology for safe pulling down of the structure and quick removal of blasted debris for fast restoration of tracks and smooth plying of trains. The three arched railway bridge (Bridge No. 61) located between Sahibganj and Karamtola cases one such example where the bridge was dismantled and the track was restored within 4 h of blasting, though the stipulated block period for demolition and restoration of tracks was 6 h. The 25.48 m long three-arched bridge was drilled and blasted with 225 number of blastholes (32 mm diameter) and 100 kg explosive (25 mm diameter). Length of blastholes varied between 0.5 and 1.8 m with blast geometry of 0.3-0.35 m burden and 0.33 m spacing. This paper deals with the conceptual and theoretical model developed for identification of the key locations for drilling and implementation of the same. It also discusses about the precautionary measures and the drilling pattern adopted for quick demolition and speedy restoration of tracks.

    Three dimensional As-built DAtabase Management System (NUSEC-ADAMS) is a system whose goal is to produce economical, speedy and accurate maintenance services of nuclear power plants by using 3D point group data. This system makes it possible to understand the plant situation remotely without field measurements. 3D point group data are collected before and after plant equipment installations, and it is stored to database after converted to viewable data on the web. Therefore, it can be shared in domestic network of a company and it can be connected with system diagram, specification of equipment, and additional information (e.g. maintenance record) by registering key information between 3D point group data and equipment's data. Thus, it reduces workload of pre-job field survey and improves work efficiency. In case of problem at a plant, if 3D as-built data is set to be seen on the network, it is possible to understand accurate information and the cause remotely in the beginning of problem. Collecting 3D point group data and updating database continuously keep as-built information up to date, therefore it improves accuracy of off-site study, and plant situation can be grasped timely. As a result, we can reduce workload and improve quality of maintenance services of nuclear power plants. (author)

    Concerns about a lack of reproducibility of statistically significant results have recently been raised in many fields, and it has been argued that this lack comes at substantial economic costs. We here report the results from prediction markets set up to quantify the reproducibility of 44 studies published in prominent psychology journals and replicated in the Reproducibility Project: Psychology. The prediction markets predict the outcomes of the replications well and outperform a survey of market participants' individual forecasts. This shows that prediction markets are a promising tool for assessing the reproducibility of published scientific results. The prediction markets also allow us to estimate probabilities for the hypotheses being true at different testing stages, which provides valuable information regarding the temporal dynamics of scientific discovery. We find that the hypotheses being tested in psychology typically have low prior probabilities of being true (median, 9%) and that a "statistically significant" finding needs to be confirmed in a well-powered replication to have a high probability of being true. We argue that prediction markets could be used to obtain speedy information about reproducibility at low cost and could potentially even be used to determine which studies to replicate to optimally allocate limited resources into replications.

    Epileptic seizure detection plays an important role in the diagnosis of epilepsy and reducing the massive workload of reviewing electroencephalography (EEG) recordings. In this work, a novel algorithm is developed to detect seizures employing log-Euclidean Gaussian kernel-based sparse representation (SR) in long-term EEG recordings. Unlike the traditional SR for vector data in Euclidean space, the log-Euclidean Gaussian kernel-based SR framework is proposed for seizure detection in the space of the symmetric positive definite (SPD) matrices, which form a Riemannian manifold. Since the Riemannian manifold is nonlinear, the log-Euclidean Gaussian kernel function is applied to embed it into a reproducing kernel Hilbert space (RKHS) for performing SR. The EEG signals of all channels are divided into epochs and the SPD matrices representing EEG epochs are generated by covariance descriptors. Then, the testing samples are sparsely coded over the dictionary composed by training samples utilizing log-Euclidean Gaussian kernel-based SR. The classification of testing samples is achieved by computing the minimal reconstructed residuals. The proposed method is evaluated on the Freiburg EEG dataset of 21 patients and shows its notable performance on both epoch-based and event-based assessments. Moreover, this method handles multiple channels of EEG recordings synchronously which is more speedy and efficient than traditional seizure detection methods.

  16. Leasing of nuclear installations

    The high costs to be borne in industrialised countries for expanding nuclear programmes make leasing, in terms of funding, an attractive proposition even in times of recession. This system is advantageous to both parties: the bodies providing funds make substantial profits without untoward risk, given the internationally-recognised regime of channelling liability onto the nuclear operator and because such contracts usually provide that ownership of the property involved will eventually be transferred to the operator. The latter obtains the sums needed by a simple, speedy procedure enabling him to start operations more quickly than if he had to seek funds by a more conventional method. The problem in Italy is that nuclear electricity generating plants are a State monopoly while leasing is a private enterprise. The Italian 1975 Siting Act provides a consultation procedure of regional and State authorities, with the ultimate decision taken by the latter. To maintain the momentum, arrangements could be made for leasing, before starting the licensing procedure proper according to the Act. (NEA) [fr

    Full Text Available To investigate the tolerance of tomato cultivars to Egyptian broomrape (Orobanche aegyptiaca pers., an experiment was conducted in a randomized complete block design with 11 treatments and 3 replications in mazrae Nemoune Astan Quds Razavi in Mashhad, Iran, 2012. Treatment were 11 varieties (Peto early CH, Sterling (Karon, Khorram, Petorak, DNP 3005, PS 6515, SPEEDY, IDEN, VADI STAR, FIRINZEH and DNP 3001 which were transplanted in the field along with broomrape. Sampling was done at two stages: 1- after appearance and establishment of broomrape on tomato root where the dry weight, stem number and node numbers of broomrape on tomato root and tomato dry weight were measured and 2- at the end of growing season where tomato fruit weight and its yield were determined. Result indicated that Sterling and Khorram cultivars did have the least broomrape dry weight, stem number and node numbers of broomrape on tomato root and while produced highest plant dry weight, fruit and yield as compared to the other cultivars. Thus, may be considered as tolerant cultivars. Petorak and DNP 3001 on the other hand, presented the most broomrape dry weight, stem number and node number on tomato root. However, Petorak, Peto early CH and FIRINZEH cultivars produced the least plant weight, fruit and yield and thus, they can be called the sensitive cultivars. DNP 3001 being highly attacked by broomrape produced increased fruit yield and therefore compensated its ill effects.

    Infectious diseases, mostly caused by bacteria and viruses but also a result of fungal and parasitic infection, have been one of the most important public health concerns throughout human history. The first step in combating these pathogens is to get a timely and accurate diagnosis at an affordable cost. Many kinds of diagnostics have been developed, such as pathogen culture, biochemical tests and serological tests, to help detect and fight against the causative agents of diseases. However, these diagnostic tests are generally unsatisfactory because they are not particularly sensitive and specific and are unable to deliver speedy results. Nucleic acid-based diagnostics, detecting pathogens through the identification of their genomic sequences, have shown promise to overcome the above limitations and become more widely adopted in clinical tests. Here we review some of the most popular nucleic acid-based diagnostics and focus on their adaptability and applicability to routine clinical usage. We also compare and contrast the characteristics of different types of nucleic acid-based diagnostics.

    Full Text Available During competition for resources in primitive networks increased fitness of an information variant does not necessarily equate with successful elimination of its competitors. If variability is added fast to a system, speedy replacement of pre-existing and less-efficient forms of order is required as novel information variants arrive. Otherwise, the information capacity of the system fills up with information variants (an effect referred as “error catastrophe”. As the cost for managing the system’s exceeding complexity increases, the correlation between performance capabilities of information variants and their competitive success decreases, and evolution of such systems toward increased efficiency slows down. This impasse impedes the understanding of evolution in prebiotic networks. We used the simulation platform Biotic Abstract Dual Automata (BiADA to analyze how information variants compete in a resource-limited space. We analyzed the effect of energy-related features (differences in autocatalytic efficiency, energy cost of order, energy availability, transformation rates and stability of order on this competition. We discuss circumstances and controllers allowing primitive networks acquire novel information with minimal “error catastrophe” risks. We present a primitive mechanism for maximization of energy flux in dynamic networks. This work helps evaluate controllers of evolution in prebiotic networks and other systems where information variants compete.

    At NPP Cernavoda-Unit 1 the fuel surveillance and the defect detection system in operation are based on monitoring the coolant activity concentration and on measuring the flux of delayed neutrons emitted by some short-lived fission products. In order to identify the failed fuel underwater non-destructive examination has to be performed. The major interest for the availability of underwater examination consists in the necessity of a speedy acquisition of the data on failed fuel in operation and of appropriate follow-up actions to be taken. Often the identification operation will be followed by more detailed examinations on selected fuel rods in the hot cells of the Post-irradiation Examination Laboratory of the Institute for Nuclear Research at Pitesti. Transfer of selected fuel rods will be done by the use of a type B(U) road transportation cask. Such an integrated approach will help to keep the level of activity concentration of the primary circuit well below the authorized limits. (author). 2 figs., 1 tab., 2 refs

    Full Text Available Abstract: Purpose: The train dispatching is a crucial issue in the train operation adjustment when passenger flow outbursts. During holidays, the train dispatching is to meet passenger demand to the greatest extent, and ensure safety, speediness and punctuality of the train operation. In this paper, a fuzzy passenger demand forecasting model is put up, then a train dispatching optimization model is established based on passenger demand so as to evacuate stranded passengers effectively during holidays. Design/methodology/approach: First, the complex features and regularity of passenger flow during holidays are analyzed, and then a fuzzy passenger demand forecasting model is put forward based on the fuzzy set theory and time series theory. Next, the bi-objective of the train dispatching optimization model is to minimize the total operation cost of the train dispatching and unserved passenger volume during holidays. Finally, the validity of this model is illustrated with a case concerned with the Beijing-Shanghai high-speed railway in China. Findings: The case study shows that the fuzzy passenger demand forecasting model can predict outcomes more precisely than ARIMA model. Thus train dispatching optimization plan proves that a small number of trains are able to serve unserved passengers reasonably and effectively. Originality/value: On the basis of the passenger demand predictive values, the train dispatching optimization model is established, which enables train dispatching to meet passenger demand in condition that passenger flow outbursts, so as to maximize passenger demand by offering the optimal operation plan.

    The Federal Government is obliged by law to install facilities for safekeeping and ultimate storage of radioactive waste, and it fulfills this duty purposefully, assigning top priority to safety. This is demonstrated by the large number of court cases in which the Federal Government firmly seeks its right vis-a-vis a State Government bent on opting out of nuclear power. Against the backdrop of the failed energy consensus talks there is no need to discontinue the speedy exploration of the Gorleben salt dome to determine its suitability as a repository, about which there can be no doubt. Comment: The Lueneburg Court of Administration recently has set aside the decision of the Ministry of the Environment of the Land Lower Saxony, to stop the exploration at the Gorleben site. The public hearing about the Konrad site has been successfully terminated after a period of 75 days. The Magdeburg Court of Administration confirmed the lawfulness of the operating permit issued for the Morsleben site, which now is allowed to receive radwaste, also from installations in the western part of Germany.

    One of the most important indicators of successful function of the International Monitoring System is existence of highly reliable communication channels providing transfer data from observation points in a real time scales. Up to present, the most communication channels were provided with existing VF-channels (Voice Frequency) that are relatively low-speedy in transfer process (4.8-9.6 kbit/sec.). In addition, reliability of the channels is insufficient because of many retransmission points. In connection with it, the special control service of MD RF decided to improve the information transfer system (ITS) installed between the observation point and National Data Center (Dubna-city). The improvement of the ITS comprises replacement of wire lines of VF-channels with satellite ones within the framework of the computer-aided satellite communication system (CASCS) M aterik . Besides it was considered to be expedient that the satellite system of data transfer from NPP to the Crisis Center of 'ROSENERGOATOM' Concern would be combined with CASCS M aterik , using the facilities of the Central Earth Station of Satellite Communication (CESSC) in Dubna. Such approach to the creation of Satellite communication has advantages in solution of radiation safety and global monitoring issues

    The postmortem examination and identification procedures performed by medical and law enforcement personnel involved in mass disaster management in Israel are reported. The Israel National Police, the Israel Defense Forces, and the L. Greenberg Institute of Forensic Medicine's experts examined 171 victims who died in 21 incidents of suicidal terrorism. The trauma sustained by the victims and perpetrators of suicidal bombings included complete body disruption and explosive, flying missile, and blast injuries. The modus operandi of the perpetrators, reconstructed from the distribution and type of injury of the victims, is discussed. Fifty-five victims perished in open space bombings and 91 inside buses. All perpetrators of these bombings died at the time of the incident regardless of their location. Identification of the victims was achieved using fingerprints, dental records, medical intervention signs, anatomic variation, genetic profile, and personal recognition. Prompt identification of the perpetrators allowed speedy apprehension of the accomplices and prevention of similar attacks. Collaboration between the different forensic, military, and law enforcement teams increased the efficiency of disaster management efforts.

    Full Text Available The success of supervizing an infectious disease depends on the ability for speedy detection and characterization of the cause and the forming of a corresponding system for examining the success of control implemented in order to prevent a recurrence of the disease. Since influenza viruses continue to circle, causing significant morbidity and mortality both among the human population and among animals all over the world, it is essential to secure the timely identification and monitoring of the strains that are in circulation. The speedy detection and characterization of new highly-virulent varieties is one of the priorities of the World Health Organization monitoring network. The implementation of molecular methods has an increasingly significant role in diagnostics and the monitoring of the influenza virus. Among a large number of molecular methods, the one particularly in use is the reverse transcription-polimerase chain reaction (PT-PCR. Technological progress in the area of the conducting of molecular methods has enabled that we can prove, in one day, using the RT-PCR method even very small quantities of the infective agent in a sample. In an obtained PCR product, we can relatively easily establish the nucleotide sequence, a detailed analysis and molecular epidemiology of the circulating strains. The molecular diagnostics procedure (RT-PCR is based on the correct choice or designing of primers depending on the desired knowledge. In order to obtain a specific diagnosis of influenza A, B or C, primers are used which multiply internal genes, such as the nucleoprotein (NP or matrix gene (M, because these are genes that are highly conserved among the virus types. In the event that we are interested in the subtype of influenza A, after obtaining a positive reaction, primers for genes of surface antigens are selected, such as hemagglutinin. Following the correct detection of the H subtype, it is possible to establish the virus virulence through the

Metabolic acidosis has a significant effect in postoperative recovery and morbidity of patients undergoing major surgery. Metabolic acidosis has a say in proper functioning of cardiovascular, renal and pulmonary system, added to severe stress full condition related to postoperative period, it bring about major shift in the speedy recovery of patient. It becomes significantly important that metabolic acidosis in diagnosed as early as possible and corrective measures are taken immediately. MATERIALS AND METHODS Study design is a prospective observational study. 109 patients who underwent elective and emergency surgeries in the department of General Surgery, Govt. Medical College Kottayam was studied for a period of 3 months (2016. On arrival of the patient, a detailed history of the patient was taken, along with emphasis to the multiple factors in the history which could be contributory to postoperative metabolic acidosis such as diabetic status, drug history, history of respiratory, cardiac and renal status. Basic preoperative laboratory investigation was carried out and its values were recorded. A preoperative arterial blood gas analysis (ABG of the patient was done before patient was taken for surgery, values of which were recorded and analysed to rule out existing acidotic status of patient, if the patient is already having metabolic acidosis he was excluded from the study. A second ABG was sent at 2 hours after induction of anaesthesia, values of which was recorded, along with the values of intraoperative fluids, preoperative Hb, duration of surgery, type of surgery, blood transfusion and colloid administration given during the time of anaesthesia. A third ABG was sent within six hours of completion of surgery and the values analysed, with due notes on postoperative care done and the days of ICU stay, for analysis and comparison

    The speedy rate of change in the environmental and socio-economics factors may increase the incidence, prevalence and risk of schistosomiasis infections in Zambia. However, available information does not provide a comprehensive understanding of the biogeography and distribution of the disease, ecology and population dynamics of intermediate host snails. The current study used an information-theoretical approach to understand the biogeography and prevalence schistosomiasis and identified knowledge gaps that would be useful to improve policy towards surveillance and eradication of intermediate hosts snails in Zambia. To summarise the existing knowledge and build on past and present experiences of schistosomiasis epidemiology for effective disease control in Zambia, a systematic search of literature for the period 2000-2017 was done on PubMed, Google Scholar and EBSCOhost. Using the key words: 'Schistosomiasis', 'Biomphalaria', 'Bulinus', 'Schistosoma mansoni', 'Schistosoma haematobium', and 'Zambia', in combination with Booleans terms 'AND' and 'OR', published reports/papers were obtained and reviewed independently for inclusion. Thirteen papers published in English that fulfilled the inclusion criteria were selected for the final review. The papers suggest that the risk of infection has increased over the years and this has been attributed to environmental, socio-economic and demographic factors. Furthermore, schistosomiasis is endemic in many parts of the country with infection due to Schistosoma haematobium being more prevalent than that due to S. mansoni. This review also found that S. haematobium was linked to genital lesions, thus increasing risks of contracting other diseases such as HIV and cervical cancer. For both S. haematobium and S. mansoni, environmental, socio-economic, and demographic factors were influential in the transmission and prevalence of the disease and highlight the need for detailed knowledge on ecological modelling and mapping the

    A digital H{sub {infinity}}controller for a permanent magnet synchronous generator (PMSG) based wind energy conversion system (WECS) is presented. Wind energy is an uncertain fluctuating resource which requires a tight control management. So, it is still an exigent task for the control design engineers. The conventional proportional-integral (PI) control is not ideal during high turbulence wind velocities, and the nonlinear behavior of the power converters. These are raising interest towards the robust control concepts. The robust design is to find a controller, for a given system, such that the closed-loop system becomes robust that assurance high-integrity and fault tolerant control system, robust H{sub {infinity}}control theory has befallen a standard design method of choice over the past two decades in industrial control applications. The robust H{sub {infinity}}control theory is also gaining eminence in the WECS. Due to the implementation complexity for the continuous H{sub {infinity}}controller, and availability of the high speedy micro-controllers, the design of a sample-data or a digital H{sub {infinity}}controller is very important for the realistic implementation. But there isn’t a single research to evaluate the performance of the digital H{sub {infinity}}controller for the WECS.

    Full Text Available Abstract Background Road traffic injuries (RTIs are a major public health problem, requiring concerted efforts both for their prevention and a reduction of their consequences. Timely arrival of the Emergency Medical Service (EMS at the crash scene followed by speedy victim transportation by trained personnel may reduce the RTIs' consequences. The first 60 minutes after injury occurrence - referred to as the "golden hour"- are vital for the saving of lives. The present study was designed to estimate the average of various time intervals occurring during the pre-hospital care process and to examine the differences between these time intervals as regards RTIs on urban and interurban roads. Method A retrospective cross-sectional study was designed and various time intervals in relation to pre-hospital care of RTIs identified in the ambulance dispatch centre in Urmia, Iran from 20 March 2005 to 20 March 2007. All cases which resulted in ambulance dispatches were reviewed and those that had complete data on time intervals were analyzed. Results In total, the cases of 2027 RTI victims were analysed. Of these, 61.5 % of the subjects were injured in city areas. The mean response time for city locations was 5.0 minutes, compared with 10.6 minutes for interurban road locations. The mean on-scene time on the interurban roads was longer than on city roads (9.2 vs. 6.1 minutes, p Conclusion The response, transport and total time intervals among EMS responding to RTI incidents were longer for interurban roads, compared to the city areas. More research should take place on needs-to and access-for EMS on city and interurban roads. The notification interval seems to be a hidden part of the post-crash events and indirectly affects the "golden hour" for victim management and it needs to be measured through the establishment of the surveillance systems.

    Full Text Available Introduction: As a result of the growing evidence on tumor radical resection in literature, simple enucleation has become one of the best techniques associated to robotic surgery in the treatment of renal neoplasia, as it guarantees minimal invasiveness and the maximum sparing of renal tissue, facilitating the use of reduced or zero ischemia techniques during resection. The use of a robotic ultrasound probe represents a useful tool to detect and define tumor location, especially in poorly exophytic small renal mass. Materials and methods: A total of 22 robotic enucleations were performed on < 3 cm renal neoplasias (PADUA score 18 Pz 6/7 e 4 Pz 8 using a 12-5 MHz robotic ultrasound probe (BK Drop-In 8826. Results: Once kidney had been isolated from the adipose capsule at the site of the neoplasia (2, the exact position of the lesion could be easily identified in all cases (22/22, even for mostly endophytic lesions, thanks to the insertion of the ultrasound probe through the assistant port. Images were produced and visualized by the surgeon using the TilePro feature of the DaVinci surgical system for producing a picture-in-picture image on the console screen. The margins of resection were then marked with cautery, thus allowing for speedy anatomical dissection. This reduced the time of ischemia to 8 min (6-13 and facilitated the enucleation technique when performed without clamping the renal peduncle (6/22. No complications due to the use of the ultrasound probe were observed. Conclusions: The use of an intraoperative robotic ultrasound probe has allowed for easier identification of small, mostly endophytic neoplasias, better anatomical approach, shorter ischemic time, reduced risk of pseudocapsule rupture during dissection, and easier enucleation in cases performed without clamping. It is noteworthy that the use of intraoperative ultrasound probe allows mental reconstruction of the tumor through an accurate 3D vision of the hidden field during

    Toxoplasma gondii infects all warm-blooded vertebrates, resulting in a great threat to human health and significant economic loss to the livestock industry. Ingestion of infectious oocysts of T. gondii from the environment is the major source of transmission. Detection of T. gondii oocysts by existing methods is laborious, time-consuming and expensive. The objective of the present study was to develop a recombinase polymerase amplification (RPA) method combined with a lateral flow (LF) strip for detection of T. gondii oocysts in the soil and water. The DNA of T. gondii oocysts was amplified by a pair of specific primers based on the T. gondii B1 gene over 15min at a constant temperature ranging from 30°C to 45°C using RPA. The amplification product was visualized by the lateral flow (LF) strip within 5min using the specific probe added to the RPA reaction system. The sensitivity of the established assay was 10 times higher than that of nested PCR with a lower detection limit of 0.1 oocyst per reaction, and there was no cross-reactivity with other closely related protozoan species. Fifty environmental samples were further assessed for the detection validity of the LF-RPA assay (B1-LF-RPA) and compared with nested PCR based on the B1 gene sequence. The B1-LF-RPA and nested PCR both showed that 5 out of the 50 environmental samples were positive. The B1-LF-RPA method was also proven to be sufficiently tolerant of existing inhibitors in the environment. In addition, the advantages of simple operation, speediness and cost-effectiveness make B1-LF-RPA a promising molecular detection tool for T. gondii. Copyright © 2017 Elsevier B.V.

These bright arrowheads, or bow shocks, can be seen in these four images taken with NASA's Hubble Space Telescope. The bow shocks form when the stars' powerful stellar winds, streams of matter flowing from the stars, slam into surrounding dense gas. The phenomenon is similar to that seen when a speeding boat pushes through water on a lake. The stars in these images are among 13 runaway stars spotted by Hubble's Advanced Camera for Surveys. The stars appear to be young, just millions of years old. Their ages are based on their colors and the presence of strong stellar winds, a signature of youthful stars. Depending on their distance from Earth, the bullet-nosed bow shocks could be 100 billion to a trillion miles wide (the equivalent of 17 to 170 solar system diameters, measured out to Neptune's orbit). The bow shocks indicate that the stars are moving fast, more than 180,000 kilometers an hour (more than 112,000 miles an hour) with respect to the dense gas they are plowing through. They are traveling roughly five times faster than typical young stars, relative to their surroundings. The high-speed stars have traveled far from their birth places. Assuming their youthful phase lasts only a million years and they are moving at roughly 180,000 kilometers an hour, the stars have journeyed 160 light-years. The Hubble observations were taken between October 2005 and July 2006.

    Over the last four decades a tremendous progress has been made in the Earth science space-based remote sensing observations, technologies and algorithms. Such advancements have improved the predictability by providing lead-time and accuracy of forecast in weather, climate, natural hazards, and natural resources. It has further reduced or bounded the overall uncertainties by partially improving our understanding of planet Earth as an integrated system that is governed by non-linear and chaotic behavior. Many countries such as the US, European Community, Japan, China, Russia, India has and others have invested billions of dollars in developing and launching space-based assets in the low earth (LEO) and geostationary (GEO) orbits. However, the wealth of this scientific knowledge that has potential of extracting monumental socio-economic benefits from such large investments have been slow in reaching the public and decision makers. For instance, there are a number of areas such as water resources and availability, energy forecasting, aviation safety, agricultural competitiveness, disaster management, air quality and public health, which can directly take advantage. Nevertheless, we all live in a global economy that depends on access to the best available Earth Science information for all inhabitants of this planet. This presentation discusses a process to transition Earth science data and products for societal needs including NASA's experience in achieving such objectives. It is important to mention that there are many challenges and issues that pertain to a number of areas such as: (1) difficulties in making a speedy transition of data and information from observations and models to relevant Decision Support Systems (DSS) or tools, (2) data and models inter-operability issues, (3) limitations of spatial, spectral and temporal resolution, (4) communication limitations as dictated by the availability of image processing and data compression techniques.

Due to trauma from accidents by speedy vehicles, falling down from height or gunshot injury particularly in human being, acquired or developmental diseases like rickets, congenital defects like abnormal bone development, wearing out because of age and overuse; lead to bone loss and to replace the loss we need the bone grafting. Osteogenesis, osteoinduction, osteoconduction, mechanical supports are the four basic mechanisms of bone graft. Bone graft can be harvested from the iliac crest, proximal tibia, proximal humerus, proximal femur, ribs and sternum. An ideal bone graft material is biologically inert, source of osteogenic, act as a mechanical support, readily available, easily adaptable in terms of size, shape, length and replaced by the host bone. Except blood, bone is grafted with greater frequency. Bone graft indicated for variety of orthopedic abnormalities, comminuted fractures, delayed unions, non-unions, arthrodesis and osteomyelitis. Bone graft can be harvested from the iliac crest, proximal tibia, proximal humerus, proximal femur, ribs and sternum. By adopting different procedure of graft preservation its antigenicity can be minimized. The concept of bone banking for obtaining bone grafts and implants is very useful for clinical application. Absolute stability require for successful incorporation. Ideal bone graft must possess osteogenic, osteoinductive and osteocon-ductive properties. Cancellous bone graft is superior to cortical bone graft. Usually autologous cancellous bone graft are used as fresh grafts where as allografts are employed as an alloimplant. None of the available type of bone grafts possesses all these properties therefore, a single type of graft cannot be recomm-ended for all types of orthopedic abnormalities. Bone grafts and implants can be selected as per clinical problems, the equipments available and preference of

    The current health care system is complex and inefficient. A simple and reliable health monitoring system that can help patients perform medical self-diagnosis is seldom readily available. Because the medical system is vast and complex, it has hampered or delayed patients in seeking medical advice or treatment in a timely manner, which may potentially affect the patient's chances of recovery, especially those with severe sicknesses such as cancer, and heart disease. The purpose of this paper is to propose a methodology in designing a simple, low cost, Internet-based health-screening platform. This health-screening platform will enable patients to perform medical self-diagnosis over the Internet. Historical data has shown the importance of early detection to ensure patients receive proper treatment and speedy recovery. The platform is designed with special emphasis on the user interface. Standard Web-based user-interface design is adopted so the user feels ease to operate in a familiar Web environment. In addition, graphics such as charts and graphs are used generously to help users visualize and understand the result of the diagnostic. The system is developed using hypertext preprocessor (PHP) programming language. One important feature of this system platform is that it is built to be a stand-alone platform, which tends to have better user privacy security. The prototype system platform was developed by the National Cheng Kung University Ergonomic and Design Laboratory. The completed prototype of this system platform was submitted to the Taiwan Medical Institute for evaluation. The evaluation of 120 participants showed that this platform system is a highly effective tool in health-screening applications, and has great potential for improving the medical care quality for the general public.

    The trial took place in July 1987, and it was a speedy trial of three weeks until the ruling from indictment reading. The court was virtually 'closed.' The accused were the following 6 persons: Director of Chernobyl NPP, power plant chief engineer, power plant deputy chief engineer, second reactor work center chief, Chernobyl NPP National Nuclear Energy Supervisory Board inspector, and power plant night shift chief. Court records or court documents have not officially published as of March 2013. These court records have been reconstructed from the memos of Nikolay Karpan (Chernobyl NPP nuclear safety ex-deputy chief engineer), who recorded them at a time when he appeared in the court as a witness, and when he attended the court for hearing. The impressions of the translator are as follows. (1) The first purpose of the trial was to promptly punish responsible persons, and to put an end to the accident. (2) Emphasis was not placed on the investigation of the accident cause or accident background. (3) As Mr. Karpan pointed out, this trial gave impression that it was 'farce' according to certain 'scenario' or 'fixed game' that was held in order to conclude that the accident was caused by the sins of accused persons. As for the defects of the nuclear reactor as the defendants pointed out, they were dismissed as 'separate issues to be addressed,' and eliminated from judgment contents. (4) All the accused denied the indictment contents (asserting the inadequacy of the reactor itself, deficiencies of regulations and documentations, and deficit of authority). However, they admitted the moral responsibility for being unable to prevent the accident. All the defendants received actual prison term of 2 to 10 years with correctional labor. (A.O.)

    The managed care revolution is sweeping the country as a result of intense marketing on the part of managed care organizations and the widespread belief that price-sensitive managed care systems will control health costs. Although few believe that managed care alone can adequately stem the growth of nation health care spending, competition based on price has emerged as a powerful force in the health care sector. Academic health center (AHCs) stand to suffer with this new managed care regime because their special missions of teaching, research, and highly specialized clinical care make them more expensive than nonacademic hospitals and place them at a noncompetitive disadvantage. The traditional focus of the acute care hospital with individual departmentally designed programs will be narrow. Major changes will be required on the part of AHCs if they are to survive and preserve patient volume, maintain the integrity of medical education, advance scientific research, and provide highly specialized care. AHCs will have to make unprecedented adjustments in virtually every phase of their operations, particularly in the areas of clinical decision making and speedy patient-related information flow. A premium will be placed on multidisciplinary, inclusive medical services that can assume total health care risks for large populations. New ways of educating students in ambulatory settings with an emphasis on outcomes and population-based health will be needed along with the traditional responsibility of pursuing new approaches to the diagnosis, treatment, and prevention of disease. The extent to which managed care will ultimately alter the traditional role of AHCs in the American health care system is unclear, but successful adaptation in the short term will require them to respond broadly, flexibly, and in a timely fashion to the anticipated health care scene.

    2018-01-01

    Full Text Available The article describes the clinical cases of acute keratoconus in three patients with Down syndrome who underwent penetrating  keratoplasty. Acute keratoconus were diagnosed in patients by examination of medical history, biomicroscopy, corneal topography,optical coherence tomography. Acute keratoconus occurs suddenly due to the rupture of Descemet’s membrane in the zone of itsstretching, when chamber moisture seeps into the thickness of the stroma, causing its swelling and perforation. If untreated, theprocess continues for 3–5 months. Most researchers recommend keratoplasty during the cold period of the disease. However, withthe threat of perforation require urgent surgical intervention. There are two effective methods of surgical treatment: epikeratophakiaand penetrating keratoplasty. Patients underwent penetrating keratoplasty. The preference for this method was given in connectionwith the following factors: young age patients (under 40 years, relatively healthy transparent peripheral zone of the cornea, whichwas observed in our patients, genetically determined diseases — Down syndrome, the threat of corneal perforation in the centre, apenchant for rubbing his eye, low vision other eye and the desire to obtain speedy optical effect along with the treatment. All patientsafter penetrating keratoplasty had improvement of visual acuity with observation periods up to 1 year. Due to the relatively highincidence of keratoconus in patients with Down syndrome should focus the attention of ophthalmologists. Thus, difficulties in thediagnosis of ophthalmic pathology in patients with concomitant Down syndrome can cause errors in verification of diagnosis and hencewrong treatment selection. In case of hydrops of the cornea penetrating keratoplasty is the choice treatment and contributes to the preservation of the eye and visual functions.

  1. The market equilibrium of OPEC's pricing mechanism

    Hammoudeh, S.; Madan, V.

    1990-01-01

    At least twice a year, oil ministers of the Organization of the Petroleum Exporting Countries (OPEC) meet in Vienna or Geneva to adjust the group's output ceiling to eliminate discrepancies between the market price and the target price. If the market imbalances are persistent, then the target price is also adjusted. Often, OPEC's members differ in their assessment of future market demand for their oil and, thus, present different views on the need to adjust the output celing and the target price. During periods of downward pressures on oil prices, the high absorbers of capital (i.e., oil revenues) prefer a speedy downward adjustment to the celing, while the low absorbers are slow to react. However, in the event of tightening markets, the low absorbers usually respond by exceeding their quotas before agreeing on a ceiling adjustment. Therefore, OPEC nations have different desirable speeds of adjustment. This paper specifies and examines the stability of OPEC's pricing mechanism. It presents a strategy which would enable the organization to achieve a target price-based market equilibrium with increased rapidity through the appropriate manipulation of the speed of output ceiling adjustment. This strategy is applied using data on market and target prices, actual output, and output ceilings for the first quarter of 1991. The main finding is that, given the target price, OPEC's equilibrium market demand is significantly lower than the assigned output ceiling. Production should have been reduced by at least 3 million barrels a day for OPEC to realize the $21 per barrel target price in the first quarter of 1991. Seasonal factors can cause slight variations in this output but would not bring out compatibility between the target price and the output ceiling within a reasonable period of time unless OPEC follows an activist policy of output adjustment. 3 figs., 1 tab

    Fortification with multiple micronutrients has been shown to improve growth and cognitive performance among children in developing countries, but it is unknown whether higher concentrations are more effective than lower concentrations. We compared the effect of 2 different concentrations of a combination of micronutrients and n-3 (omega-3) fatty acids on indicators of growth and cognitive performance in low-income, marginally nourished schoolchildren in Bangalore, India. In a 2-by-2 factorial, double-blind, randomized controlled trial, 598 children aged 6-10 y were individually allocated to 1 of 4 intervention groups to receive foods fortified with either 100% or 15% of the Recommended Dietary Allowance of micronutrients in combination with either 900 mg alpha-linolenic acid plus 100 mg docosahexaenoic acid or 140 mg alpha-linolenic acid for 12 mo. Anthropometric and biochemical assessments were performed at baseline and 12 mo. Cognitive performance was measured at baseline and at 6 and 12 mo. The high micronutrient treatment significantly improved linear growth at 12 mo (0.19 cm; 0.01, 0.36) and short-term memory at 6 mo (0.11 SD; 0.01, 0.20) and was less beneficial on fluid reasoning at 6 (-0.10 SD; -0.17, -0.03) and 12 (-0.12 SD; -0.20, -0.04) mo than was the low micronutrient treatment, whereas no differences were observed on weight, retrieval ability, cognitive speediness, and overall cognitive performance. No significant differences were found between the n-3 treatments. The high micronutrient treatment was more beneficial for linear growth than was the low micronutrient treatment. However, with some small differential effects, higher micronutrient concentrations were as effective as lower concentrations on cognitive performance. This trial was registered at clinicaltrials.gov as NCT00467909.

    Globalisation and interregional exchange of people, goods, and services has boosted the importance of and reliance on all kinds of transport networks. The linear structure of road networks is especially sensitive to natural hazards. In southern Norway, steep topography and extreme weather events promote frequent traffic disruption caused by debris flows. Topographic susceptibility and trigger frequency maps serve as input into a hazard appraisal at the scale of first-order catchments to quantify the impact of debris flows on the road network in terms of a failure likelihood of each link connecting two network vertices, e.g. road junctions. We compute total additional traffic loads as a function of traffic volume and excess distance, i.e. the extra length of an alternative path connecting two previously disrupted network vertices using a shortest-path algorithm. Our risk metric of link failure is the total additional annual traffic load, expressed as vehicle kilometres, because of debris-flow-related road closures. We present two scenarios demonstrating the impact of debris flows on the road network and quantify the associated path-failure likelihood between major cities in southern Norway. The scenarios indicate that major routes crossing the central and north-western part of the study area are associated with high link-failure risk. Yet options for detours on major routes are manifold and incur only little additional costs provided that drivers are sufficiently well informed about road closures. Our risk estimates may be of importance to road network managers and transport companies relying on speedy delivery of services and goods.

    Full Text Available Background: The most important prerequisites for neurosurgeries are brain relaxation, need of stable haemodynamics with less fluctuation in intracranial pressure and speedy recovery from anaesthesia. Endotracheal intubation is the major stressful stimuli that can elicit a marked pressor response. Various drugs have been used to attenuate these reflexes. Dexmedetomidine, a highly selective alpha 2-adrenoceptor agonist, have neuroprotective, cardioprotective, and sedative effects so it is potentially useful during neuroanaesthesia. This is a prospective randomised control trial carried out to see whether administration of Dexmedetomidine prior to intubation can attenuate the various haemodynamic responses, intraocular pressure (IOP and the requirement of induction dose of propofol in control and study group. Materials and Methods: Fifty patients (ASA grade 1, 2 scheduled for intracranial tumour surgeries were divided into two groups (25 each. Group D received Dexmedetomidine 0.8 μg/kg i.v. over 10 mins and group C received 20 ml saline. Anaesthesia induced with Propofol, dose adjusted using bispectral index monitor. The groups were compared with IOP, Heart rate (HR, Mean arterial pressure (MAP, and dose of Propofol required for induction. Results : Groups were well matched for their demographic data and pre-operative. IOP in both the eyes decreases significantly after premedication and remained below baseline even after 10 th min of intubation in group D while in Group C; it increased significantly after intubation and remained above baseline. The difference between groups was also statistically significant. HR and MAP decreased significantly in patients of group D compared to group C (P < 0.05. Patients were more haemodynamicaly stable at all time points after premedication in group D (P < 0.05. Propofol requirements for induction was lesser in group D (P < 0.05. Bradycardia and hypotension incidences were higher in group D. Conclusion

    Endoscopic submucosal dissection (ESD) is currently widely conducted for the treatment of early gastrointestinal -cancers. Due to the characteristic anatomy of the large intestine, needle- tip type devices such as Dual knife are mainly used in colorectal ESD. On the other hand, the non- needle-tip type IT knife is a unique device with an insulated tip, and has been reported to be safe, efficacious and speedy when used in gastric ESD. A new model of IT knife, IT knife nano, anticipated to be useful for esophageal and colorectal ESD has become available, but its usefulness has not been reported. Therefore, we performed this study to evaluate the usefulness of IT knife nano for ESD of large colorectal lesions. Previous studies have shown that a tumor size of 40 mm or above significantly prolongs treatment time and is a factor of treatment difficulty. We selected colorectal lesions of 40 mm and above, and compared 32 lesions treated with Dual knife alone before IT knife nano was available (No-IT group) and 40 cases treated with IT knife nano as a second knife after IT knife nano became available (IT group). We assessed en bloc resection rate, complete en bloc resection rate, complication rate and treatment time. The en bloc resection rates in No-IT group and IT group were 100% and 97.5%, respectively, with no significant difference. The respective median treatment time was 70 min and 51 min, and was significantly shortened in IT group (P knife nano in ESD for large colorectal -lesions achieves the same levels of efficacy and safety as conventional device, with the additional merit of shortening treatment time. © Acta Gastro-Enterologica Belgica.

    1967-01-01

    The evaluation work to provide accurate and consistent neutron cross-section data for multigroup neutronics calculations is not fully exploiting the available theoretical and experimental results; this has been so particularly since the introduction of on-line data handling techniques enabled experimenters to turn out vast quantities of numbers. This situation can be radically improved only by mechanizing the evaluation processes. Systems such as the SC1SRS tape will not only largely overcome the task of collecting data but will provide speedy access to it; by using computers and graph-plotting machines to tabulate and display this data, the labour of evaluation can be very greatly reduced. With some types of cross-section there is hope that by using modern curve-fitting techniques the actual evaluation and statistical accounting of the data can be performed automatically. Some areas where automatic evaluation would seem likely to succeed are specified and a discussion of the mathematical difficulties incurred, such as the elimination of anomalous data, is given. Particularly promising is the use of splines in the mechanized evaluation of data. Splines are the mathematical analogues of the draughtsman's spline used in drawing smooth curves. Their principal properties are the excellent approximations they give to the derivatives of a function; in contrast to conventional polynomial fitting, this feature ensures good interpolation and, when required, stable extrapolation. Various methods of using splines in data graduation and the problem of marrying these methods to standard statistical procedures are examined. The results of work done at AWRE with cubic splines on the mechanized evaluation of neutron scattering total cross-section and angular distribution data are presented. (author)

    Full Text Available Abstract Background Existing scientific literature is a rich source of biological information such as disease markers. Integration of this information with data analysis may help researchers to identify possible controversies and to form useful hypotheses for further validations. In the context of proteomics studies, individualized proteomics era may be approached through consideration of amino acid substitutions/modifications as well as information from disease studies. Integration of such information with peptide searches facilitates speedy, dynamic information retrieval that may significantly benefit clinical laboratory studies. Description We have integrated from various sources annotated single amino acid polymorphisms, post-translational modifications, and their documented disease associations (if they exist into one enhanced database per organism. We have also augmented our peptide identification software RAId_DbS to take into account this information while analyzing a tandem mass spectrum. In principle, one may choose to respect or ignore the correlation of amino acid polymorphisms/modifications within each protein. The former leads to targeted searches and avoids scoring of unnecessary polymorphism/modification combinations; the latter explores possible polymorphisms in a controlled fashion. To facilitate new discoveries, RAId_DbS also allows users to conduct searches permitting novel polymorphisms as well as to search a knowledge database created by the users. Conclusion We have finished constructing enhanced databases for 17 organisms. The web link to RAId_DbS and the enhanced databases is http://www.ncbi.nlm.nih.gov/CBBResearch/qmbp/RAId_DbS/index.html. The relevant databases and binaries of RAId_DbS for Linux, Windows, and Mac OS X are available for download from the same web page.

    Multi-analytes simultaneous monitoring of amino acid and monoamine neurotransmitters (NTs) has important scientific significance for their related pathology, physiology and drug screening. In this work, in virtue of a mass spectrometry sensitizing reagent 10-ethyl-acridone-3-sulfonyl chloride (EASC) as derivatization reagent, an Ultra High Performance Liquid Chromatography-Tandem Mass Spectrometry (UHPLC-MS/MS) method was developed and validated for simultaneous determination of six amino acid NTs, two monoamine ones and its one metabolite. The simple and rapid derivatization reaction was innovatively combined with plasma preparation by using EASC acetonitrile solution as protein precipitant. This interesting combination brought the advantages of speediness, simpleness and high-throughput in a cost-effective way. Under the optimized conditions, LODs (0.004-3.80nM) and LOQs (0.014-13.3nM) of EASC derivatized-NTs were calculated and found to be significantly lower than those of direct UHPLC-MS/MS detection about 11.5-275.0 and 14.4-371.4 times, respectively. Moreover, EASC derivatization significantly improved chromatographic resolution and matrix effect when compared with direct UPLC-MS/MS detection method without derivatization. Meanwhile, it also brought acceptable precision (3.0-13.0%, peak area CVs%), accuracy (86.4-112.9%), recovery (88.3-107.8%) and stability (3.8-8.5%, peak area CVs%) results. This method was successfully applied for the antiparkinsonian effect evaluation of levodopa and Ginsenoside Rg1 using PC12 cells and rats models by measuring multiple NTs. This provided a new method for the NTs related studies in the future. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Rice genome sequencing projects have generated remarkable amount of information about genes and genome architecture having tremendous potential to be utilized in both basic and applied research. Success in transgenics is paving the way for preparing a road map of functional genomics which is expected to correlate action of a gene to a trait in cellular and organismal context. However, the lack of a simple and efficient method for transformation and regeneration is a major constraint for such studies in this important cereal crop. Results In the present study, we have developed an easy, rapid and highly efficient transformation and regeneration protocol using mature seeds as explants and found its successful applicability to a choice of elite indica rice genotypes. We have optimized various steps of transformation and standardized different components of the regeneration medium including growth hormones and the gelling agent. The modified regeneration medium triggers production of large number of shoots from smaller number of calli and promotes their faster growth, hence significantly advantageous over the existing protocols where the regeneration step requires maximum time. Using this protocol, significantly higher transformation efficiency (up to 46% and regeneration frequency (up to 92% for the untransformed calli and 59% for the transformed calli were achieved for the four tested cultivars. We have used this protocol to produce hundreds of independent transgenic lines of different indica rice genotypes. Upon maturity, these transgenic lines were fertile thereby indicating that faster regeneration during tissue culture did not affect their reproductive potential. Conclusions This speedy, yet less labor-intensive, protocol overcomes major limitations associated with genetic manipulation in rice. Moreover, our protocol uses mature seeds as the explant, which can easily be obtained in quantity throughout the year and kept

    A new design of a miniaturized, atmospheric-pressure, low-power (e.g., battery-operated), self-igniting, planar-geometry microplasma device (MPD) for use with liquid microsamples is described. The inexpensive MPD was a hybrid, three-substrate quartz-plastic-plastic structure and it was formed on chips with area the size of a small postage stamp. The substrates were chosen for rapid prototyping and for speedy device-geometry testing and evaluation. The approximately 700-microm (diameter) and 7-mm (long) He-H(2) (3% H(2)) microplasma was formed by applying high-voltage ac between two needle electrodes. Operating conditions were found to be critical in sustaining stable microplasma on plastic substrates. Spectral interference from the electrode materials was not observed. A small-size, electrothermal vaporization system was used for introduction of microliter volumes of liquids into the MPD. The microplasma was operated from an inexpensive power supply. And, operation from a 14.4-V battery has been demonstrated. Microplasma background emission in the spectral range between 200 and 850 nm obtained using a portable, fiber-optic spectrometer is reported. Analyte emission from microliter volumes of dilute single-element standard solutions of Cd, Cu, K, Li, Mg, Mn, Na, Pb, and Zn is documented. Element-dependent precision was between 10-25% (the average was 15%) and detection limits ranged between 1.5 and 350 ng. The system was used for the determination of Na in diluted bottled-water samples.

    2014-01-01

    Background The current health care system is complex and inefficient. A simple and reliable health monitoring system that can help patients perform medical self-diagnosis is seldom readily available. Because the medical system is vast and complex, it has hampered or delayed patients in seeking medical advice or treatment in a timely manner, which may potentially affect the patient’s chances of recovery, especially those with severe sicknesses such as cancer, and heart disease. Objective The purpose of this paper is to propose a methodology in designing a simple, low cost, Internet-based health-screening platform. Methods This health-screening platform will enable patients to perform medical self-diagnosis over the Internet. Historical data has shown the importance of early detection to ensure patients receive proper treatment and speedy recovery. Results The platform is designed with special emphasis on the user interface. Standard Web-based user-interface design is adopted so the user feels ease to operate in a familiar Web environment. In addition, graphics such as charts and graphs are used generously to help users visualize and understand the result of the diagnostic. The system is developed using hypertext preprocessor (PHP) programming language. One important feature of this system platform is that it is built to be a stand-alone platform, which tends to have better user privacy security. The prototype system platform was developed by the National Cheng Kung University Ergonomic and Design Laboratory. Conclusions The completed prototype of this system platform was submitted to the Taiwan Medical Institute for evaluation. The evaluation of 120 participants showed that this platform system is a highly effective tool in health-screening applications, and has great potential for improving the medical care quality for the general public.

    Full Text Available People have developed ceremonies and rituals to help make sense or celebrate an alteration in position, circumstance or relationship. However, over time some have become diluted or rejected for whom they are intended. In majority of cultures, the greatest effort is given to the death rite of passage– and yet paradoxically it is the one that is now most often distorted or lost. This study attempted to describe the multiple aspects of changes that are occurring in Gurung death rite. Gurungs are followers of ‘Bonism’ but they are under the profound influence of Tibetan Mahayani Lamaism. Gurung community is changing from Mechanical to Organic Solidarity in which the Mechanical Unity of their traditional culture is transforming to loosely united Organic Solidarity of body. Gurung death rites have been influenced by many rudiments--migration, urbanization and modernization due to which there has been the emergence of deformed usages and behaviors in death rite. Urbanization impact on death rite is closely linked to modernization and the sociological process of rationalization, a speedy and historic transformation of Gurung social roots whereby predominantly rural Gurung culture is being rapidly modified by urban ostentatious culture. However, there is very vital element of unity, cooperation, sympathy and we feeling among the Gurungs owing to death rite that has tied all Gurungs under a shared and endorsed bond. It has created a reciprocal relationship between the living and dead-- both depending upon each other. Death rituals have been a means of co-ordination creating solidarity through ‘Syaisyai’ which is a social institution for uniting the Gurungs. This bond between giver and gift, the act of giving creates a social bond in Gurung community with an obligation to reciprocate on part of the recipient.

    Together with evidence of higher bleeding tendencies, the vulnerability of the South-Asian population to anemia secondary to a higher prevalence of hemoglobinopathies and micronutrient deficiencies merits further exploration of the effects of tranexamic acid on this population. Additionally, limited access to self-care facilities and certain sociocultural beliefs and practices may not be conducive to a speedy recovery from surgical complications. The aim of this study is to investigate the effects of intraoperative administration of tranexamic acid during total knee arthroplasty when considering the South-Asian population. Medical record files of 355 patients who underwent total knee arthroplasty (2007-2015) were reviewed to collect data regarding patient characteristics, surgical variables and post-operative complications. Unilateral and Bilateral total knee arthroplasty were studied separately. Analysis was done using t-test, Mann-Whitney U test, chi-square and Fisher's exact square where appropriate. The threshold for significance was p tranexamic acid caused a significant reduction in estimated blood loss (p-value=0.011), total operative time, calculated blood loss, and hemoglobin change (p-valuetranexamic acid only caused a significant reduction in calculated blood loss (p-value tranexamic acid vs. those who did not, there was a significant increase in length of hospital stay (ptranexamic acid effectively reduces intraoperative blood loss, it does not have an effect on the need for post-operative blood transfusions. The increased length of stay and special care unit admissions associated with tranexamic acid use should be explored further to reveal the complete safety profile of tranexamic acid administration in the South-Asian population during total knee arthroplasty.

    Full Text Available A digital H∞ controller for a permanent magnet synchronous generator (PMSG based wind energy conversion system (WECS is presented. Wind energy is an uncertain fluctuating resource which requires a tight control management. So, it is still an exigent task for the control design engineers. The conventional proportional-integral (PI control is not ideal during high turbulence wind velocities, and the nonlinear behavior of the power converters. These are raising interest towards the robust control concepts. The robust design is to find a controller, for a given system, such that the closed-loop system becomes robust that assurance high-integrity and fault tolerant control system, robust H∞ control theory has befallen a standard design method of choice over the past two decades in industrial control applications. The robust H∞ control theory is also gaining eminence in the WECS. Due to the implementation complexity for the continuous H∞ controller, and availability of the high speedy micro-controllers, the design of a sample-data or a digital H∞ controller is very important for the realistic implementation. But there isn’t a single research to evaluate the performance of the digital H∞ controller for the WECS. In this paper, the proposed digital H∞ controller schemes comprise for the both generator and grid interactive power converters, and the control performances are compared with the conventional PI controller and the fuzzy controller. Simulation results confirm the efficacy of the proposed method Energies 2013, 6 2085 which are ensured the WECS stabilities, mitigate shaft stress, and improving the DC-link voltage and output power qualities.

    Enhanced Recovery After Surgery (ERAS) pathways are known to decrease complications and duration of stay in colorectal surgery patients. However, it is unclear whether an ERAS pathway would be feasible and effective at a safety-net hospital. The aim of this study was to identify local barriers and facilitators before the adoption of an ERAS pathway for patients undergoing colorectal operations at a safety-net hospital. Semistructured interviews were conducted to assess the perceived barriers and facilitators before ERAS adoption. Stratified purposive sampling was used. Interviews were audiotaped, transcribed verbatim, and analyzed using content analysis. Analytic and investigator triangulation were used to establish credibility. Interviewees included 8 anesthesiologists, 5 surgeons, 6 nurses, and 18 patients. Facilitators identified across the different medical professions were (1) feasibility and alignment with current practice, (2) standardization of care, (3) smallness of community, (4) good teamwork and communication, and (5) caring for patients. The barriers were (1) difficulty in adapting to change, (2) lack of coordination between different departments, (3) special needs of a highly comorbid and socioeconomically disadvantaged patient population, (4) limited resources, and (5) rotating residents. Facilitators identified by the patients were (1) welcoming a speedy recovery, (2) being well-cared for and satisfied with treatment, (3) adequate social support, (4) welcoming early mobilization, and (5) effective pain management. The barriers were (1) lack of quiet and private space, (2) need for more patient education and counseling, and (3) unforeseen complications. Although limited hospital resources are perceived as a barrier to ERAS implementation at a safety-net hospital, there is strong support for such pathways and multiple factors were identified that may facilitate change. Inclusion of patient perspectives is critical to identifying challenges and

    The importance of the leak detection of a buried pipe in a power plant of Korea is being emphasized as the buried pipes of a power plant are more than 20 years old. The first objective of this work is to develop new technologies for leak detection of a buried pipe. The second objective is to design and fabricate a trial product of leakage detection system for buried pipe. To achieve these purposes, as a first step, literature survey of the leak detection methods and techniques has been performed. As an algorithm for enhancing the leak detection capability of newly developed leakage detection system, an algorithm for removing mechanical noise and reflected wave within the pipe has been developed, and its feasibility was verified by performing numerical simulations and experiments. The hardware for leakage detection system is designed as a portable type by considering the test environment of a power plant, where speedy leakage inspection and rapid movement/reinstallation of the inspection equipment is necessary. The software is designed to provide a user-friendly GUI(Graphic User Interface) environment, making the system setup and data display quick and easy. It is also designed to allow for a real time visualization of analysis results on a monitoring screen for an estimation of the leakage location. The feature of the developed leak detection system is that it equipped with noise rejection algorithms that can effectively enhance the leak detection capability in a noisy environment. Then, a trial product of the leakage detection system has been fabricated, and its functionality and capability were verified by field experiments. The experimental results demonstrated that even in a noisy environment, the developed system can provide more reliable means for estimating the leak location of the buried pipe. It is expected that the reliability of leakage point estimation can be enhanced when the developed leak detection system is applied to a leakage estimation problem

    In this work, we presented a three-dimensional (3D) molecularly imprinted electrochemical sensor (MIECS) with novel strategy for ultrasensitive and specific quantification of metolcarb based on prussian blue (PB) mediated amplification combined with signal enhancement of ordered mesoporous carbon. The molecularly imprinted polymers were synthesized by electrochemically induced redox polymerization of para aminobenzoic acid (p-ABA) in the presence of template metolcarb. Ordered mesoporous carbon material (CMK-3) was introduced to enhance the electrochemical response by improving the structure of the modified electrodes and facilitating charge transfer processes of PB which was used as an inherent electrochemical active probe. The modification process for the working electrodes of the MIECS was characterized by scanning electron microscope (SEM) and cyclic voltammetry (CV), and several important parameters controlling the performance of the MIECS were investigated and optimized in detail. The MIECS with 3D structure had the advantages of ease of preparation, high porous surface structure, speedy response, ultrasensitivity, selectivity, reliable stability, good reproducibility and repeatability. Under the optimal conditions, the MIECS offered an excellent current response for metolcarb in the linear response range of 5.0 × 10(-10)-1.0 × 10(-4) mol L(-1) and the limit of detection (LOD) was calculated to be 9.3 × 10 (-11)mol L(-1) (S/N = 3). The proposed MIECS has been successfully applied for the determination of metolcarb in real samples with satisfactory recoveries. Furthermore, the construction route of this ultrasensitive 3D MIECS may provide a guideline for the determination of non-electroactive analytes in environmental control and food safety.

    The historical background of the play, the developments at the Roman court affecting Octavia, extends from the year 48, when Octavia's engagement to Lucius Junius Silanus was broken off in anticipation of Agrippina's marriage to Emperor Claudius early in 49, to be followed by a new engagement  to Agrippina's son, the later Emperor Nero, to 62, when Nero's planned marriage to Poppaea Sabina led to Octavia's exile and speedy execution on a false charge of adultery. In this temporal frame, the paper highlights the following milestones in Octavia's life: Agrippina's appointment of the philosopher Lucius Annaeus Seneca as tutor to her son Domitius (later known as Nero in 49 AD; Claudius' adoption of Agrippina's son on 25 February 50 AD; the proclamation of thirteen-year-old Nero's coming of age in March 51; Nero's marriage to Octavia in 53; the death of Claudius and Nero's rise to power in 54; Nero's murder of Britannicus in 55, and of his mother, Agrippina, four years later (59; Nero's affair with Poppaea Sabina, whom he had met in 58, and their wedding in 62, as well as Octavia's exile and execution in the same year. But despite the close bearing of these events on Octavia's fate, she is largely or completely ignored in most written sources on the topic. Rather than attempt to disentangle the many questions raised by Octavia's little known life, the paper thus gives a mere outline of her life story, trapped in the dynastic intrigues of the contemporary Roman court, which are luridly depicted in the tragedy Octavia, formerly attributed to Seneca.

    Full Text Available Abstract Background Given the costs associated with the management of musculoskeletal pain in primary care, predicting the course of these conditions remains a research priority. Much of the research into prognostic indicators however considers musculoskeletal conditions in terms of single pain sites whereas in reality, many patients present with pain in more than one site. The aim of this study was to identify prognostic factors for early improvement in primary care consulters with acute and persistent musculoskeletal conditions across a range of pain sites. Methods Consecutive patients with a new episode of musculoskeletal pain completed self-report questionnaires at baseline, and then again at the 4/5th treatment visit, and if they were still consulting, at the 10th visit. The outcome was defined as patient self-report improvement sufficient to make a meaningful difference. Independent predictors of outcome were identified using multivariate regression analyses. Results Acute (th visit. Several variables at baseline were associated with improvement at the 4/5th visit, but the predictive models were weak and unable to discriminate between patients who were improved and those who were not. In contrast, it was possible to elicit a predictive model for improvement later on at the 10th visit, but only in patients with persistent pain. Being employed, reporting a decline in work fear-avoidance behaviour at the 4/5th visit, and being better by the 4/5th visit, were all independently associated with improvement. This model accounted for 34.3% (p Conclusions We were unable to identify baseline characteristics that predicted early outcome in musculoskeletal pain patients. However, early self-reported improvement and decline in work fear-avoidance behaviour as predictors of later improvement highlighted the importance of speedy recovery in persistent musculoskeletal pain consulters. Our findings reinforce the elusive nature of baseline predictors, and

    As a result of the growing evidence on tumor radical resection in literature, simple enucleation has become one of the best techniques associated to robotic surgery in the treatment of renal neoplasia, as it guarantees minimal invasiveness and the maximum sparing of renal tissue, facilitating the use of reduced or zero ischemia techniques during resection. The use of a robotic ultrasound probe represents a useful tool to detect and define tumor location, especially in poorly exophytic small renal mass. A total of 22 robotic enucleations were performed on < 3 cm renal neoplasias (PADUA score 18 Pz 6/7 e 4 Pz 8) using a 12-5 MHz robotic ultrasound probe (BK Drop-In 8826). Once kidney had been isolated from the adipose capsule at the site of the neoplasia (2), the exact position of the lesion could be easily identified in all cases (22/22), even for mostly endophytic lesions, thanks to the insertion of the ultrasound probe through the assistant port. Images were produced and visualized by the surgeon using the TilePro feature of the DaVinci surgical system for producing a picture-in-picture image on the console screen. The margins of resection were then marked with cautery, thus allowing for speedy anatomical dissection. This reduced the time of ischemia to 8 min (6-13) and facilitated the enucleation technique when performed without clamping the renal peduncle (6/22). No complications due to the use of the ultrasound probe were observed. The use of an intraoperative robotic ultrasound probe has allowed for easier identification of small, mostly endophytic neoplasias, better anatomical approach, shorter ischemic time, reduced risk of pseudocapsule rupture during dissection, and easier enucleation in cases performed without clamping. It is noteworthy that the use of intraoperative ultrasound probe allows mental reconstruction of the tumor through an accurate 3D vision of the hidden field during surgical dissection.

    Full Text Available This paper demonstrates how the short messaging service SMS popularly known as texting has facilitated production of solutions to farm issues using the Farmers Text Centre FTC of the Philippine Rice Research PhilRice as the case study. Text messages registered in the FTC database in 2010 covering one cropping season were discourse analyzed. Interpretive qualitative research particularly the Grounded Theory was employed to interprettheorize said data. Since texting is a new emerging discourse in agricultural development Grounded Theory allows the explication of theoretical accounts that explain its existence and impact. Results indicate that timing queries received within working days from 8am to 5pm get speedy response content the easier the question the faster it gets reply length the shorter the message the better and clarity of the querytext message as well as cultural factors such as greetings and terms of respect are all important governing factors in texting for farm use. Moreover analysis reveals that the series of text messages sent back and forth by farmers and agricultural specialist in FTC suggests a dynamic process of negotiation rather than passive information sharing. The analysis further reveals that texting has allowed farmers to have access to a negotiated knowledge rather than a standard scientific recommendation vis--vis the solution to their farm issues. The term negotiated implies that farmers are actively involved in knowledge production via texting. Textholder is coined in this paper to describe farmers and agricultural specialists as co-creators of knowledge in texting as opposed to their traditional role as knowledge generator and user respectively. From the analysis reflections implications and theoretical contributions are drawn in relation to the value of SMSing in agricultural extension and communication.

  6. Status of French breeder development and German-French cooperation

    The development of fast breeder reactors in France is at present characterized by the successful operation of the 250 MW reactor, Phenix, and the speedy progress made in construction of the 1200 MW Superphenix plant. The technical concept of Superphenix is a logical extension of the Phenix concept, i.e., the pool type sodium cooled breeder reactor. While the only change in the primary system has been an increase in capacity, the main modification over Phenix is the change from small modular steam generators to four large units. The development of the work to date does not cast any doubt upon the envisaged date of first criticality in the second half of 1982. The basis of German-French cooperation is a joint declaration by the then Ministers for Research of the two countries on February 13, 1976 in which the Ministers had expressed themselves in favor of close cooperation between both countries in the development of safe, reliable and economic fast breeder reactors. On this basis, the two governments, the research centers and the industrial partners in the two countries, including the previous partners in Belgium, the Netherlands and Italy, agreed on the general principles of this cooperation. Meanwhile, the cooperation formalized in 1977 has been activated. Both in research and development and among planning and building industries the exchange of know-how and cooperation is in full swing. The joint company, SERENA, is the pool for the know-how introduced by the partners and the sole representative of the partners in the scheme. (orig.) 891 UA [de

  7. Is Late or Non-Payment a Significant Problem to Malaysian Contractors?

    2007-12-01

    Full Text Available Some developed countries have drawn lip construction-specific statutory security of payment acts/legislations typically known as Construction Contracts Act to eliminate poor payment practices and to assist continuous uninterrupted construction works. Malaysia too cannot pretend not to have these problems. This paper presents findings of a study conducted amongst Malaysian contractors with the aims to determine the seriousness of late and non- payment problems; to identify the main causes and effects of late and non-payment; and to identify ways to sustain the payment flows in the Malaysian construction industry. The study focused on contractual payments from the paymaster (government or private to the contractors. The main factors for late and nonpayment in the construction industry identified from the study include: delay in certification, paymaster's poor financial management, local culture/attitude, pay master's failure to implement good governance in business, underpayment of certified amounts by the pay master and the use of 'pay when paid' clauses in contracts. The research findings show that late and non-payment can create cash flow problems, stress and financial hardship on the contractors. Amongst the most appropriate solutions to overcome the problem of late and non-payment faced by local contractors include: a right to regular periodic payment, a right to a defined time frame (or payment and a right to a speedy dispute resolution mechanism. Promptness of submitting, processing, issuing interim payment certificates and honouring the certificates are extremely important issues in relation to progress payment claims. Perhaps, an increased sense of professionalism in construction industry could overcome some of the problems related to late and non- payment issues.

    2009-07-01

    Full Text Available Abstract Background There is increasing evidence that the environment plays a role in influencing physical activity in children and adults. As children have less autonomy in their behavioural choices, neighbourhood environment supportiveness may be an important determinant of their ability to be active. Yet we know rather little about the types of environment that children use for bouts of physical activity. This study uses accelerometery and global positioning system technologies to identify the charactieristics of environments being used for bouts of continuous moderate to vigorous physical activity (MVPA in a sample of English schoolchildren. Methods The study used a convenience sample of 100 children from SPEEDY (Sport, Physical activity and Eating behaviour: Environmental Determinants in Young people, a cohort of 2064 9–10 year-olds from Norfolk, England, recruited in 2007. Children wore an ActiGraph GT1M accelerometer and a Garmin Forerunner 205 GPS unit over four consecutive days. Accelerometery data points were matched to GPS locations and bouts (5 minutes or more of MVPA were identified. Bout locations were overlaid with a detailed landcover dataset developed in a GIS to identify the types of environment supporting MVPA. Findings are presented using descriptive statistics. Results Boys were also more active than girls, spending an average of 20 (SD 23 versus 11 (SD 15 minutes per day in MVPA bouts. Children who spent more time outside the home were more active (p = 0.002, especially girls and children living in rural locations (both p Conclusion The study has developed a new methodology for the identification of environments in which bouts of continuous physical activity are undertaken. The results highlight the importance of the provision of urban gardens and greenspaces, and the maintenance of safe street environments as places for children to be active.

    While undernutrition and anaemia have previously been linked to poor development of children, relatively little is known about the role of B-vitamins and fatty acids on cognition. The present study aims to explore the associations between indicators of body size, fatty acid and micronutrient status on cognitive performance in 598 Indian school children aged 6-10 years. Baseline data of a clinical study were used to assess these associations by analyses of variance adjusting for age, sex, school, maternal education and cognitive tester. The Kaufman Assessment Battery for Children II was used to measure four cognitive domains, including fluid reasoning, short-term memory, retrieval ability and cognitive speediness. Scores were combined into an overall measure, named mental processing index (MPI). Body size indicators and Hb concentrations were significantly positively related to cognitive domains and MPI, such that increases of 1 sd in height-for-age and weight-for-age z-scores would each translate into a 0.09 sd increase in MPI, P = 0.0006 and 0.002, respectively. A 10 g/l increase in Hb concentrations would translate into a 0.08 sd increase in MPI, P = 0.0008. Log-transformed vitamin B12 concentrations were significantly inversely associated with short-term memory, retrieval ability and MPI (beta (95 % CI) = - 0.124 (- 0.224, - 0.023), P = 0.02). Other indicators of Fe, iodine, folate and fatty acid status were not significantly related to cognition. Our findings for body size, fatty acids and micronutrients were in agreement with previous observational studies. The inverse association of vitamin B12 with mental development was unexpected and needed further study.

    Modern cancer research often involves large datasets and the use of sophisticated statistical techniques. Together these add a heavy computational load to the analysis, which is often coupled with issues surrounding data accessibility. Connectivity mapping is an advanced bioinformatic and computational technique dedicated to therapeutics discovery and drug re-purposing around differential gene expression analysis. On a normal desktop PC, it is common for the connectivity mapping task with a single gene signature to take > 2h to complete using sscMap, a popular Java application that runs on standard CPUs (Central Processing Units). Here, we describe new software, cudaMap, which has been implemented using CUDA C/C++ to harness the computational power of NVIDIA GPUs (Graphics Processing Units) to greatly reduce processing times for connectivity mapping. cudaMap can identify candidate therapeutics from the same signature in just over thirty seconds when using an NVIDIA Tesla C2050 GPU. Results from the analysis of multiple gene signatures, which would previously have taken several days, can now be obtained in as little as 10 minutes, greatly facilitating candidate therapeutics discovery with high throughput. We are able to demonstrate dramatic speed differentials between GPU assisted performance and CPU executions as the computational load increases for high accuracy evaluation of statistical significance. Emerging 'omics' technologies are constantly increasing the volume of data and information to be processed in all areas of biomedical research. Embracing the multicore functionality of GPUs represents a major avenue of local accelerated computing. cudaMap will make a strong contribution in the discovery of candidate therapeutics by enabling speedy execution of heavy duty connectivity mapping tasks, which are increasingly required in modern cancer research. cudaMap is open source and can be freely downloaded from http://purl.oclc.org/NET/cudaMap.

    The First World War produced a huge number of disabled soldiers. During the war, surgeons realized that it was not enough to merely treat the limbs of the wounded soldiers; it was also necessary to train them to use their remaining abilities to their greatest capacity. Governments at the same time realized that such a high number of veterans created a financial burden, by entitling disabled veterans to full healthcare, raising the issues of social welfare. Both in the US and Europe, programs of rehabilitation were instituted, providing injured soldiers with long-term medical care and vocational training aimed at restituting soldier's independence for a speedy return to work. In Italy at the Istituto Ortopedico Rizzoli, one of the most renowned Hospitals for the treatment of orthopedic deformities, Putti set up a technologically advanced Orthopedic Workshop, and a Rehabilitation House. The so called "reconstruction programs" addressed all aspects of rehabilitation (including physiotherapy, curative workshops and vocational therapy), seeing disability in terms of function. The experience gained in the treatment of war victims markedly enriched rehabilitation techniques, but overall the First World War helped engender the concept of rehabilitative programs to assist disabled veterans reintegrate in the workplace, thus laying the foundations of the modern concept of participation at a social level. In the centenary of Italy's entry into the First World War, it is worth underlining just how much hindsight affords us a new perspective on Physical Medicine and Rehabilitation. It reminds us that rehabilitation is not merely the role of medicine, but forms part of a multifaceted approach involving societal roles and expectations, regardless of the psychological and physical impairments suffered by the individuals concerned.

    Objective: The objective of the paper was to compare the satisfaction of hydrophilic-coated catheters (HC) (SpeediCath, Coloplast Canada, Mississauga, ON) versus uncoated catheters in a pediatric neurogenic bladder population, in order to identify a target group for HC. The main hypothesis was that our patients, with regard to their limitations, might have difficulties using the HC. Material and methods: A comparative prospective study was initiated in one pediatric rehabilitation centre. Out of the 39 patients who tried the HC during a routine clinic visit, 31 patients/parents accepted to participate in a 1-week trial and to answer a satisfaction questionnaire. Their medical records were reviewed for age, neurological disease, intellectual deficit, impaired dexterity and method of catheterization (Mitrofanoff/urethra). Results: Thirty of the 31 patients answered the satisfaction questionnaire. The median age for the 30 patients was 13.5 years (range 6–20 years). Of these patients, 19 were females (63%), 26 performed self-catheterization (87%), and 6 had Mitrofanoff (20%). Ten children (33%) would be ready to proceed with HC and all 10 children would receive catheterization by the urethra. Of these, 9 were females (90%), 8 used compact-HC (80%) and all were self-sufficient. Patients using compact-HC would continue with this catheter. In the patient comments, males catheterizing per-urethra and patients using a continent stoma requiring long catheters had problems with the excess of lubricant. Conclusion: Most children preferred their usual uncoated catheter and would not change for HC. Female patients catheterizing per-urethra with a compact-HC seem to benefit most from this catheter.

    Full Text Available The war criminals of World War II had speedy trials in the former socialist countries. Only those perpetrators who had succeeded in leaving their countries before the victory of the anti-fascist alliance were spared the death penalty. Some of them could live for decades peacefully in their new homelands – especially in both Americas. For decades Argentina was a safe haven for European war criminals. This was also the case with Dinko Šakić who had been a commander of the notorious Ustasha-camp Jasenovac for several months in 1944. After the international recognition of the Republic of Croatia at the beginning of 1992, Šakić seemed to have felt utterly at ease and drew considerable attention upon himself – by giving interviews (on TV and in newspapers and scandalous comments about the Ustasha-regime – so that eventually the Croatian legal institutions started dealing with him. Having established the existence of a founded suspicion that Dinko Šakić as the commander of Jasenovac camp on the territory of the »Independent State of Croatia« allegedly committed a criminal offence, a war crime against the civilian population as defined by Article 120, Paragraph 1 of the Basic Criminal Law of the Republic of Croatia, the investigation judge issued a decree on April 21, 1998 and subsequently Šakić’s extradition was requested from the Republic of Argentina. The county State Attorney filed the indictment on December 14, 1998 and the trial at the Zagreb County Court began on March 15, 1999 and was terminated after 56 days of trial. The judgement was pronounced on October 1, 1999: Šakić was found guilty on all charges but two and sentenced to the highest punishment of 20 years in prison. The verdict and the penalty were confirmed by the first and second Appeals Chamber in 2000.

  14. The value captor's process: getting the most out of your new business ventures.

    2007-05-01

    The high failure rate among new business ventures is usually chalked up to the fundamental uncertainty of the process. In actuality, say McGrath and Keil, flawed ways of assessing and managing ventures may account for the disappointing amount of value they generate. Instead of taking the go/no-go approach, whereby a project either advances toward launch or is killed, decision makers should consider a range of alternatives: recycling the venture by aiming it at a new target market; spinning it off to other owners or a joint venture; spinning it in to an established business unit; or salvaging useful elements such as technologies, capabilities, knowledge, and patents. Firms that excel in value extraction--the "value captors" whose practices and mind-set this article explores--have created formal processes to systematically mine successes, failures, and everything in between. They know that a venture should be treated like a scientific experiment, in which learning plays a critical role. They are ready to seize new opportunities if a venture falters on its original course. They foster networks to promote cooperation and collaboration between established business leaders and venture teams and involve people from throughout the company in the venture review process. They don't allow financial criteria to dominate the reviews, and they recognize that the best people to launch a business may not be the ones who developed the idea. If your innovation pipeline is dry, your promising projects are being strangled for lack of a speedy payback, or someone else has made a fabulous business out of a slightly altered idea that you abandoned, consider the value captor's path.

    Full Text Available Abstract Background and aims There still is a lack of prospective studies on bone mineral development in patients with a history of early onset Anorexia nervosa (AN. Therefore we assessed associations between bone mass accrual and clinical outcomes in a former clinical sample. In addition to an expected influence of regular physical activity and hormone replacement therapy, we explored correlations with nutritionally dependent hormones. Methods 3-9 years (mean 5.2 ± 1.7 after hospital discharge, we re-investigated 52 female subjects with a history of early onset AN. By means of a standardized approach, we evaluated the general outcome of AN. Moreover, bone mineral content (BMC and bone mineral density (BMD as well as lean and fat mass were measured by dual-energy x-ray absorptiometry (DXA. In a substudy, we measured the serum concentrations of leptin and insulin-like growth factor-I (IGF-I. Results The general outcome of anorexia nervosa was good in 50% of the subjects (BMI ≥ 17.5 kg/m2, resumption of menses. Clinical improvement was correlated with BMC and BMD accrual (χ2 = 5.62/χ2 = 6.65, p = 0.06 / p = 0.036. The duration of amenorrhea had a negative correlation with BMD (r = -.362; p th percentile. IGF-I serum concentrations corresponded to the general outcome of AN. By contrast, leptin serum concentrations showed great variability. They correlated with BMC and current body composition parameters. Conclusions Our results from the main study indicate a certain adaptability of bone mineral accrual which is dependent on a speedy and ongoing recovery. While leptin levels in the substudy tended to respond immediately to current nutritional status, IGF-I serum concentrations corresponded to the individual's age and general outcome of AN.

  16. BDI position on energy policy and energy market deregulation

    Secure energy supplies are indispensable for our modern way of life and our economy. Energy policy is a part of economic policy and must be shaped within the magic triangle of objectives, i.e. security, competitiveness, environmental compatibility. As a result of their outstanding role, electricity and natural gas, with respective shares of 70% in industrial energy use and 85% in energy costs, are in the focus of energy policy interest of the Federation of German Industries (BDI). One important development over the past few years has been the deregulation of the markets for electricity and gas. However, the markedly lower electricity rates to be paid by industry, commercial tariff consumers, and private customers are being offset by new burdens arising from government intervention and taxes. Other dirigistic interventions into the energy market by the red-green federal government since 1998, referred to as 'turning point of energy policy', are invalidating what market opening had been achieved. With a view to a sustainable energy policy for the future, BDI pleads in favor of a broad energy mix. In a mix neutral with respect to competition, this includes the classical energy sources, the renewables, and low-cost, environmentally friendly nuclear power. In principle, it is the forces of the market, coupled with responsible action, which are to steer further developments. On a European level, speedy implementation of the opening of the electricity and gas markets, as decided, should be urged. It is important that the leeway won as a result of deregulation not be constrained again by new regulations. More market, less regulation, and more direct responsibility must provide room for a powerful energy supply system under the premises of the triangle of objectives referred to above. (orig.) [de

    Full Text Available On the basis of the earliest accounting records of the Hospitale misericordiae initiated after the Great Earthquake of 6 April 1667 and other sources, the infl uence of the earthquake on the work of the foundling home has been examined. Payment frequency made to the wet nurses in the seven months after the earthquake suggests normalization of the activities of the state charitable institution during the crisis caused by the natural disaster. The swift recovery of the activities of the state foundling home, the fi rst payments being made some twenty days after the earthquake, points to the government’s intention to restore the work of the institutions whose role was not essential to the survival of the state. Thus the death of three out of four administrators and the likely heavily damaged building of the foundling home were clearly not an impediment to the payment of the wet nurses on 1 May, nor to the re-establishment of the regular accounting records on 15 June, nor to the reception of new wards. The majority of the wet nurses noted in the accounting records until the end of 1667 lived in Rijeka and Župa dubrovačka, the rural areas closest to the city. Some wet nurses cared for more than one ward, and at least half of the breastfeeding contracts made in the fi rst years after the earthquake lasted one year or longer. The state funding of the foundling home of 300 perpers per month proved adequate and was established promptly after the earthquake. The speedy recovery of the administration of the Hospitale misericordiae is an eloquent testimony to the accumulated knowledge and experience of Dubrovnik’s government in dealing with the crisis situation.

  18. Predictors of business return in New Orleans after Hurricane Katrina.

    Nina S N Lam

    Full Text Available We analyzed the business reopening process in New Orleans after Hurricane Katrina, which hit the region on August 29, 2005, to better understand what the major predictors were and how their impacts changed through time. A telephone survey of businesses in New Orleans was conducted in October 2007, 26 months after Hurricane Katrina. The data were analyzed using a modified spatial probit regression model to evaluate the importance of each predictor variable through time. The results suggest that the two most important reopening predictors throughout all time periods were the flood depth at the business location and business size as represented by its wages in a logarithmic form. Flood depth was a significant negative predictor and had the largest marginal effects on the reopening probabilities. Smaller businesses had lower reopening probabilities than larger ones. However, the nonlinear response of business size to the reopening probability suggests that recovery aid would be most effective for smaller businesses than for larger ones. The spatial spillovers effect was a significant positive predictor but only for the first nine months. The findings show clearly that flood protection is the overarching issue for New Orleans. A flood protection plan that reduces the vulnerability and length of flooding would be the first and foremost step to mitigate the negative effects from climate-related hazards and enable speedy recovery. The findings cast doubt on the current coastal protection efforts and add to the current debate of whether coastal Louisiana will be sustainable or too costly to protect from further land loss and flooding given the threat of sea-level rise. Finally, a plan to help small businesses to return would also be an effective strategy for recovery, and the temporal window of opportunity that generates the greatest impacts would be the first 6∼9 months after the disaster.

  20. The Need for More Earthquake Science in Southeast Asia

    Many regions within SE Asia have as great a density of active seismic structures as does the western US - Sumatra, Myanmar, Bangladesh, New Guinea and the Philippines come first to mind. Much of Earth's release of seismic energy in the current millennium has, in fact, come from these regions, with great losses of life and livelihoods. Unfortunately, the scientific progress upon which seismic-risk reduction in SE Asia ultimately depends has been and continues to be slow. Last year at AGU, for example, I counted 57 talks about the M6 Napa earthquake. In contrast, I can't recall hearing any talk on a SE Asian M6 earthquake at any venue in the past many years. In fact, even M7+ earthquakes often go unstudied. Not uncommonly, the region's earthquake scientists face high financial and political impediments to conducting earthquake research. Their slow speed in the development of scientific knowledge doesn't bode well for speedy progress in the science of seismic hazards, the sine qua non for substantially reducing seismic risk. There are two basic necessities for the region to evolve significantly from the current state of affairs. Both involve the development of regional infrastructure: 1) Data: Robust and accessible geophysical monitoring systems would need to be installed, maintained and utilized by the region's earth scientists and their results shared internationally. Concomitantly, geological mapping (sensu lato) would need to be undertaken. 2) People: The training, employment, and enduring support of a new, young, international corps of earth scientists would need to accelerate markedly. The United States could play an important role in achieving the goal of significant seismic risk reduction in the most seismically active countries of SE Asia by taking the lead in establishing a coalition to robustly fund a multi-decadal program that supports scientists and their research institutions to work alongside local expertise.

    While significant capacity has been built in the field of web-based coastal mapping and informatics in the last decade, little has been done to take stock of the implications of these efforts or to identify best practice in terms of taking lessons learned into consideration. This study reports on the second of two transatlantic workshops that bring together key experts from Europe, the United States and Canada to examine state-of-the-art developments in coastal web atlases (CWA), based on web enabled geographic information systems (GIS), along with future needs in mapping and informatics for the coastal practitioner community. While multiple benefits are derived from these tailor-made atlases (e.g. speedy access to multiple sources of coastal data and information; economic use of time by avoiding individual contact with different data holders), the potential exists to derive added value from the integration of disparate CWAs, to optimize decision-making at a variety of levels and across themes. The second workshop focused on the development of a strategy to make coastal web atlases interoperable by way of controlled vocabularies and ontologies. The strategy is based on web service oriented architecture and an implementation of Open Geospatial Consortium (OGC) web services, such as Web Feature Services (WFS) and Web Map Service (WMS). Atlases publishes Catalog Web Services (CSW) using ISO 19115 metadata and controlled vocabularies encoded as Uniform Resource Identifiers (URIs). URIs allows the terminology of each atlas to be uniquely identified and facilitates mapping of terminologies using semantic web technologies. A domain ontology was also created to formally represent coastal erosion terminology as a use case, and with a test linkage of those terms between the Marine Irish Digital Atlas and the Oregon Coastal Atlas. A web interface is being developed to discover coastal hazard themes in distributed coastal atlases as part of a broader International Coastal

    The European Council held in Laeken in December 2001 had decided to call a convention preparing the next conference of the heads of state and government which, among other topics, was to deliberate the question of a fully formulated European constitution. Under the presidency of Giscard d'Estaing, all delegates to the European Convention on July 10, 2003 signed the draft treaty for a European constitution. This final document is the basis of the conference of the heads of state and government to begin in October 2003. On this occasion, the draft of a separate chapter on energy could well come up again for examination. This chapter had been introduced only at the end of the deliberations of the convention and adds to the competences of the EU institutions. Also the Euratom Treaty was a topic of the convention preparing the constitution. As the presidency felt that no specific issues had been raised in the Laeken declaration, it is proposed to adapt the Euratom Treaty to the new provisions of the constitution by adding a protocol. This would mean that the European Atomic Energy Community, for the time being, would retain its independent legal status. The contents would have to be examined at some later date. Consequently, the real discussion of the Euratom Treaty is yet to come. Also, the speedy completion of the single market for electricity would make it desirable for the Community to adopt a uniform, positive stance in the use of nuclear power at the best possible safety standards so as to ensure a level playing field. Current events entailing power failures in the United States and the United Kingdom have alerted the public to the problem of the continuity of power supply. This could well be the beginning of a new, unbiased, balanced energy discussion in a bigger Europe. (orig.)

    MODIFIED PAPER TITLE AND ABSTRACT DUE TO SLIGHTLY MODIFIED SCOPE: TITLE: Nonlinear Force Profile Used to Increase the Performance of a Haptic User Interface for Teleoperating a Robotic Hand Natural movements and force feedback are important elements in using teleoperated equipment if complex and speedy manipulation tasks are to be accomplished in hazardous environments, such as hot cells, glove boxes, decommissioning, explosives disarmament, and space. The research associated with this paper hypothesizes that a user interface and complementary radiation compatible robotic hand that integrates the human hand’s anthropometric properties, speed capability, nonlinear strength profile, reduction of active degrees of freedom during the transition from manipulation to grasping, and just noticeable difference force sensation characteristics will enhance a user’s teleoperation performance. The main contribution of this research is in that a system that concisely integrates all these factors has yet to be developed and furthermore has yet to be applied to a hazardous environment as those referenced above. In fact, the most prominent slave manipulator teleoperation technology in use today is based on a design patented in 1945 (Patent 2632574) [1]. The robotic hand/user interface systems of similar function as the one being developed in this research limit their design input requirements in the best case to only complementing the hand’s anthropometric properties, speed capability, and linearly scaled force application relationship (e.g. robotic force is a constant, 4 times that of the user). In this paper a nonlinear relationship between the force experienced between the user interface and the robotic hand was devised based on property differences of manipulation and grasping activities as they pertain to the human hand. The results show that such a relationship when subjected to a manipulation task and grasping task produces increased performance compared to the

    Silk Road is located on the Deep Web and provides an anonymous transacting infrastructure for the retail of drugs and pharmaceuticals. Members are attracted to the site due to protection of identity by screen pseudonyms, variety and quality of product listings, selection of vendors based on reviews, reduced personal risks, stealth of product delivery, development of personal connections with vendors in stealth modes and forum activity. The study aimed to explore vendor accounts of Silk Road as retail infrastructure. A single and holistic case study with embedded units approach (Yin, 2003) was chosen to explore the accounts of vendor subunits situated within the Silk Road marketplace. Vendors (n=10) completed an online interview via the direct message facility and via Tor mail. Vendors described themselves as 'intelligent and responsible' consumers of drugs. Decisions to commence vending operations on the site centred on simplicity in setting up vendor accounts, and opportunity to operate within a low risk, high traffic, high mark-up, secure and anonymous Deep Web infrastructure. The embedded online culture of harm reduction ethos appealed to them in terms of the responsible vending and use of personally tested high quality products. The professional approach to running their Silk Road businesses and dedication to providing a quality service was characterised by professional advertising of quality products, professional communication and visibility on forum pages, speedy dispatch of slightly overweight products, competitive pricing, good stealth techniques and efforts to avoid customer disputes. Vendors appeared content with a fairly constant buyer demand and described a relatively competitive market between small and big time market players. Concerns were evident with regard to Bitcoin instability. The greatest threat to Silk Road and other sites operating on the Deep Web is not law enforcement or market dynamics, it is technology itself. Copyright © 2013 Elsevier

  6. Final storage of radioactive waste in Germany. Waste arisings and availability of a repository as seen by an electricity utility

    2004-01-01

    The management of waste arising in the operation of nuclear power plants has been taken into account since the beginnings of the peaceful uses of nuclear power in Germany. As early as in 1957, a memorandum of the German Advisory Committee on Atomic Energy contains a reference to the need for safe disposal of radioactive waste. Legislation adopted the suggestion and laid down some provisions on the safe utilization of radioactive materials as early as in the Atomic Energy Act of December 23, 1959. In connection with the nuclear waste management center, the Federal Republic also looked for a suitable site for a repository. After thorough site selection proceedings by the federal government and the state of Lower Saxony, the Lower Saxony state government in 1977 defined Gorleben as the site. The decision has been preceded by a three-stage selection process in which more than 140 sites had been investigated. Exploration of the Gorleben site began in 1979 and was interrupted on October 1, 2000 to clarify conceptual and safety-related doubts of the federal government. The German Federal Ministry for the Environment (BMU) seeks to make a repository (for high-level waste) available in 2030. Technically, it is still possible to commission a repository for waste generating heat at Gorleben after 2025 if the salt dome is found to be suitable after speedy conclusion of the exploration work. Reference is made to foreseeable problem areas. Another project pursued by the federal government is the use of the Konrad mine as a repository for low and medium-level radioactive waste. After well over twenty years, the plans approval decision was made in May 2002 and is at present the subject of litigation.

    This report covers the topics of pandemics, epidemics and partnerships, including regulatory convergence initiatives, new technologies and novel vaccines, discussed by leading public and private sector stakeholders at the 18th Annual General Meeting (AGM) of the Developing Countries Vaccine Manufacturers' Network (DCVMN). Contributions of Gavi and the vaccine industry from emerging countries to the growing global vaccine market, by improving the supply base from manufacturers in developing countries and contributing to 58% of doses, were highlighted. The Coalition for Epidemic Preparedness Innovations (CEPI), the International Vaccine Institute (IVI) and others reported on new strategies to ensure speedy progress in preclinical and clinical development of innovative vaccines for future MERS, Zika or other outbreak response. Priorities for vaccine stockpiling, to assure readiness during emergencies and to prevent outbreaks due to re-emerging diseases such as yellow fever, cholera and poliomyelitis, were outlined. The role of partnerships in improving global vaccine access, procurement and immunization coverage, and shared concerns were reviewed. The World Health Organization (WHO) and other international collaborating partners provided updates on the Product, Price and Procurement database, the prequalification of vaccines, the control of neglected tropical diseases, particularly the new rabies elimination initiative, and regulatory convergence proposals to accelerate vaccine registration in developing countries. Updates on supply chain innovations and novel vaccine platforms were presented. The discussions enabled members and partners to reflect on efficiency of research & development, supply chain tools and trends in packaging technologies improving delivery of existing vaccines, and allowing a deeper understanding of the current public-health objectives, industry financing, and global policies, required to ensure optimal investments, alignment and stability of

    The number of people being affected by Diabetes mellitus worldwide is increasing at an alarming rate. Monitoring of the diabetic condition and its effects on the human body are therefore of great importance. Of particular interest is diabetic retinopathy (DR) which is a result of prolonged, unchecked diabetes and affects the visual system. DR is a leading cause of blindness throughout the world. At any point of time 25 - 44% of people with diabetes are afflicted by DR. Automation of the screening and monitoring process for DR is therefore essential for efficient utilization of healthcare resources and optimizing treatment of the affected individuals. Such automation would use retinal images and detect the presence of specific artifacts such as hard exudates, hemorrhages and soft exudates (that may appear in the image) to gauge the severity of DR. In this paper, we focus on the detection of hard exudates. We propose a two step system that consists of a screening step that classifies retinal images as normal or abnormal based on the presence of hard exudates and a detection stage that localizes these artifacts in an abnormal retinal image. The proposed screening step automatically detects the presence of hard exudates with a high sensitivity and positive predictive value (PPV ). The detection/localization step uses a k-means based clustering approach to localize hard exudates in the retinal image. Suitable feature vectors are chosen based on their ability to isolate hard exudates while minimizing false detections. The algorithm was tested on a benchmark dataset (DIARETDB1) and was seen to provide a superior performance compared to existing methods. The two-step process described in this paper can be embedded in a tele-ophthalmology system to aid with speedy detection and diagnosis of the severity of DR.

    Full Text Available The number of mutations underlining b-thalassemia generate a wide variety of different clinical phenotypes. An understanding of the genotype is important for medical personnel in order to provide proper counseling to patients and their families. Characterization of these mutations should aid the planning of a prenatal diagnosis program for bthalassemia. The heterogeneity of the mutations makes it difficult and time consuming to identify the mutation in some individuals. We developed a single-tube multiplex amplification refractory mutation system (multiplex ARMS to identify common ethnic- specific b-thalassemia mutations. Confirmation of multiplex ARMS results was carried out using direct sequencing. Three thousand three hundred twenty two people from Phitsanulok province were screened for the b-thalassemia trait by quantitation of HbA2 with microcolumn chromatography and the genotypes of mutations were characterized using multiplex ARMS and direct sequencing. We found that the deletion at codons 41/42 (-TCTT was the most frequent (48%, codon 17 (A®T (30%, -28 (A®G (6% and IVS-I-1(G®T (6% were the second and third in frequency respectively. A -87 (C®A mutation (4%, IVS II-654 (C®T (2%, codons 71/72 (+A (2% and codon 35 (C®A mutations (2% were also found. These techniques were found to be a valuable tool for analysis of b-thalassemia mutations because they are accurate, simple, and speedy in operation. The application for the diagnosis of severe thalassemia in high-risk pregnancies is promising.

    Full Text Available Malaysia is a speedy developing country and now struggling to become a developed country with a first class infrastructural network. Towards the vision, various developments have been well planned especially in building construction sectors in order to fulfill the need of society and an organization. In the hasty stream of building construction whether government, private or personal building, the facilities management planning should not be neglected. The planning of building and facilities management before, during and after a building creation must be parallel to maintain the initial condition of the building and to ensure the surrounding of the building is always in good quality, safe and healthy to all occupants or visitors of the building. Practically the construction management only focuses on before and after building construction. Otherwise the facilities management should focus on three levels that are before, during and after construction. Nowadays, many issues reflected to quality, safety and health originated from the weakness of facilities management especially building maintenance aspect such as impairment, fire, collapse, failure compliance of law and so on. Such events will threat the safety and health of the occupants and visitors of buildings. So, the quality, safety and health practices are two essential elements in building maintenance to ensure that all occupants always comfortable, safe and healthy during occupation of a building. This paper discussed a few factors that should be considered by facilities management organization to maintain a good level of quality, safe and healthy of a building. Some of the factors are developing objective, policy and strategy; implementation of planning; providing budget; procedure development, regulation and standard compliance; and human resources.

    Observing another person performing a complex action accelerates the observer's acquisition of the same action and limits the time-consuming process of learning by trial and error. Observational learning makes an interesting and potentially important topic in the developmental domain, especially when disorders are considered. The implications of studies aimed at clarifying whether and how this form of learning is spared by pathology are manifold. We focused on a specific population with learning and intellectual disabilities, the individuals with Williams syndrome. The performance of twenty-eight individuals with Williams syndrome was compared with that of mental age- and gender-matched thirty-two typically developing children on tasks of learning of a visuo-motor sequence by observation or by trial and error. Regardless of the learning modality, acquiring the correct sequence involved three main phases: a detection phase, in which participants discovered the correct sequence and learned how to perform the task; an exercise phase, in which they reproduced the sequence until performance was error-free; an automatization phase, in which by repeating the error-free sequence they became accurate and speedy. Participants with Williams syndrome beneficiated of observational training (in which they observed an actor detecting the visuo-motor sequence) in the detection phase, while they performed worse than typically developing children in the exercise and automatization phases. Thus, by exploiting competencies learned by observation, individuals with Williams syndrome detected the visuo-motor sequence, putting into action the appropriate procedural strategies. Conversely, their impaired performances in the exercise phases appeared linked to impaired spatial working memory, while their deficits in automatization phases to deficits in processes increasing efficiency and speed of the response. Overall, observational experience was advantageous for acquiring competencies

    Malaysia is a developing country in Southeast Asia, with rapid industrial and economic growth. Speedy population growth and aggressive consumerism in the past five decades have resulted in environmental pollution issues, including products containing polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs). PCBs and PBDEs are classified as persistent organic pollutants (POPs) by the Stockholm Convention due to their persistence, bioaccumulation in the environment and toxicity to humans and wildlife. These compounds are known to cause liver dysfunction, thyroid toxicity, developmental neuro-toxicity and possibly cancer. PCBs in air, mussels, pellets, seawater, fresh water, and human breast milk samples were analyzed in Malaysia, while studies on the pollution level of PBDEs in Malaysia were conducted on mussels, soils, leachate and sediment samples. PCBs in breast milk collected from Malaysia was the highest among Asian developing countries, with mean concentration of 80 ng/g lipid weight. On the other hand, the mean concentration of PCBs in mussels collected from Malaysia recorded the second lowest, with 56 ng/g and 89 ng/g lipid weight in two studies respectively. The concentrations of PBDEs in mussels taken from Malaysia fall in the range of 0.84-16 ng/g lipid weight, which is considerably low compared to 104.5 ng/g lipid weight in Philippines and 90.59 ng/g in Korea. Nevertheless, there are limited studies on these compounds in Malaysia, particularly there is no research on PBDEs in breast milk and sediment samples. This review will summarize the contamination levels of PCBs and PBDEs in different samples collected from Asian countries since 1988 until 2010 with a focus on Malaysia and will provide needed information for further research in this field.

    The present study examines seasonal and temporal patterns in food-related content of two UK magazines for young women focusing on food types, cooking and weight loss. Content analysis of magazines from three time blocks between 1999 and 2011. Desk-based study. Ninety-seven magazines yielding 590 advertisements and 148 articles. Cluster analysis of type of food advertising produced three clusters of magazines, which reflected recognised food behaviours of young women: vegetarianism, convenience eating and weight control. The first cluster of magazines was associated with Christmas and Millennium time periods, with advertising of alcohol, coffee, cheese, vegetarian meat substitutes and weight-loss pills. Recipes were prominent in article content and tended to be for cakes/desserts, luxury meals and party food. The second cluster was associated with summer months and 2010 issues. There was little advertising for conventional foods in cluster 2, but strong representation of diet plans and foods for weight loss. Weight-loss messages in articles focused on short-term aesthetic goals, emphasising speedy weight loss without giving up nice foods or exercising. Cluster 3 magazines were associated with post-New Year and 2005 periods. Food advertising was for everyday foods and convenience products, with fewer weight-loss products than other clusters; conversely, article content had a greater prevalence of weight-loss messages. The cyclical nature of magazine content - indulgence and excess encouraged at Christmas, restraint recommended post-New Year and severe dieting advocated in the summer months - endorses yo-yo dieting behaviour and may not be conducive to public health.

    To examine how the Australian media portrays the childbearing body through the use of celebrity stories in women's magazines. The study aimed to provide insight into socially constructed factors that might influence women's body image and expectations during pregnancy and the early postnatal period. Media content analysis was used to analyse 25 celebrity stories about the childbearing postnatal body (images and texts) collected from Australia's three leading women's magazines between January and June 2009 (n=58). A variety of persuasive textual and visual messages were elicited. The major theme representing how the postnatal body was constructed was labelled 'Bouncing back'; the focus of this paper. The social messages inherent in the magazine stories were that women need to strive towards regaining a pre-pregnant body shape with the same effort one would employ when recovering from an illness. Three specific sub-themes that promoted weight loss were identified. These were labelled 'Racing to bounce back', 'Breastfeeding to bounce back' and 'Pretending to bounce back'. A fourth sub-theme, 'Refusing to bounce back: Celebrating my new body', grouped together stories about celebrities who appeared to embrace their changed, but healthy, postnatal body. The study highlighted the expectations of the postpartum body in relation to speedy return to the pre-pregnant state. Understanding how these portrayals may contribute to women's own body image and expectations in the early postpartum period may better assist maternity health care providers to engage with women in meaningful discussions about this important time in their lives and challenge notions of ideal body types. Assisting women to accept and nurture themselves and have confidence in their ability as a new parent is a crucial element of quality maternity service provision.

    Ophthalmology departments face intensifying pressure to expedite sight-saving treatments and reduce the global burden of disease. The use of electronic communication systems, digital imaging, and redesigned service care models is imperative for addressing such demands. The recently developed Scottish Eyecare Integration Project involves an electronic referral system from community optometry to the hospital ophthalmology department using National Health Service (NHS) email with digital ophthalmic images attached, via a virtual private network connection. The benefits over the previous system include reduced waiting times, improved triage, e-diagnosis in 20% without the need for hospital attendance, and rapid electronic feedback to referrers. We draw on the experience of the Scottish Eyecare Integration Project and discuss the global applications of this and other advances in teleophthalmology. We focus particularly on the implications for management and screening of chronic disease, such as glaucoma and diabetic eye disease, and ophthalmic disease, such as retinopathy of prematurity where diagnosis is almost entirely and critically dependent on fundus appearance. Currently in Scotland, approximately 75% of all referrals are electronic from community to hospital. The Scottish Eyecare Integration Project is globally the first of its kind and unique in a national health service. Such speedy, safe, and efficient models of communication are geographically sensitive to service provision, especially in remote and rural regions. Along with advances in teleophthalmology, such systems promote the earlier detection of sight-threatening disease and safe follow-up of non-sight-threatening disease in the community.

    The importance of the leak detection of a buried pipe in a power plant of Korea is being emphasized as the buried pipes of a power plant are more than 20 years old. The first objective of this work is to develop new technologies for leak detection of a buried pipe. The second objective is to design and fabricate a trial product of leakage detection system for buried pipe. To achieve these purposes, as a first step, literature survey of the leak detection methods and techniques has been performed. As an algorithm for enhancing the leak detection capability of newly developed leakage detection system, an algorithm for removing mechanical noise and reflected wave within the pipe has been developed, and its feasibility was verified by performing numerical simulations and experiments. The hardware for leakage detection system is designed as a portable type by considering the test environment of a power plant, where speedy leakage inspection and rapid movement/reinstallation of the inspection equipment is necessary. The software is designed to provide a user-friendly GUI(Graphic User Interface) environment, making the system setup and data display quick and easy. It is also designed to allow for a real time visualization of analysis results on a monitoring screen for an estimation of the leakage location. The feature of the developed leak detection system is that it equipped with noise rejection algorithms that can effectively enhance the leak detection capability in a noisy environment. Then, a trial product of the leakage detection system has been fabricated, and its functionality and capability were verified by field experiments. The experimental results demonstrated that even in a noisy environment, the developed system can provide more reliable means for estimating the leak location of the buried pipe. It is expected that the reliability of leakage point estimation can be enhanced when the developed leak detection system is applied to a leakage estimation problem

    Full Text Available This paper presents a proposed set of the novel technique, methods, and algorithm for simultaneous path planning, area exploration, area retrieval, obstacle avoidance, object detection, and object retrieval   autonomously by a multi-robot system. The proposed methods and algorithms are built considering the use of low cost infrared sensors with the ultimate function of efficiently exploring the given unknown area and simultaneously identifying desired objects by analyzing the physical characteristics of several of the objects that come across during exploration. In this paper, we have explained the scenario by building a coordinative multi-robot system consisting of two autonomously operated robots equipped with low-cost and low-range infrared sensors to perform the assigned task by analyzing some of the sudden changes in their environment. Along with identifying and retrieving the desired object, the proposed methodology also provide an inclusive analysis of the area being explored. The novelties presented in the paper may significantly provide a cost-effective solution to the problem of area exploration and finding a known object in an unknown environment by demonstrating an innovative approach of using the infrared sensors instead of high cost long range sensors and cameras. Additionally, the methodology provides a speedy and uncomplicated method of traversing a complicated arena while performing all the necessary and inter-related tasks of avoiding the obstacles, analyzing the area as well as objects, and reconstructing the area using all these information collected and interpreted for an unknown environment. The methods and algorithms proposed are simulated over a complex arena to depict the operations and manually tested over a physical environment which provided 78% correct results with respect to various complex parameters set randomly.

    Full Text Available Background: Information and Communication Technologies (ICTs are gaining popularity in South Africa; this includes the use of mobile phones and the Internet. Mobile phones also seem to be popular with the student cohort of the South African population, especially for communication purposes. Empirical evidence affirms the importance of mobile phones to this cohort, including the need to research further how these groups use and experience such devices. Objectives: This study seeks to provide an understanding of how mobile phone features, the motivation to use and time spent on a mobile phone influence behavioural intention to use mobile phones among a sample of technical and vocational educational and training (TVET students in the Eastern Cape Province of South Africa. Method: A survey was carried out with 161 TVET students through a self-administered questionnaire completed by each respondent. Pre-testing and pilot testing of measures were conducted using a sample of final-year students using mobile phones who fit the same characteristics as the intended sample. To arrive at findings, data analysis was undertaken through the Chi-square test. Results: Descriptive results of the study reveal that the majority of mobile phones owned by TVET students were in the category of smartphones, bearing modern features that facilitate instant messaging, exchange of data and information as well as speedy access to information via the Internet. Conclusion: Inferential results of the study indicate that the more features a mobile phone has, the higher the desire to make use of the phone for communication purposes. Furthermore, motivation and time were found to play insignificant roles in influencing student utilisation of mobile phones for communication purposes.

    2008-12-01

    When laser ranger is transported or used in field operations, the transmitting axis, receiving axis and aiming axis may be not parallel. The nonparallelism of the three-light-axis will affect the range-measuring ability or make laser ranger not be operated exactly. So testing and adjusting the three-light-axis parallelity in the production and maintenance of laser ranger is important to ensure using laser ranger reliably. The paper proposes a new measurement method using digital image processing based on the comparison of some common measurement methods for the three-light-axis parallelity. It uses large aperture off-axis paraboloid reflector to get the images of laser spot and white light cross line, and then process the images on LabVIEW platform. The center of white light cross line can be achieved by the matching arithmetic in LABVIEW DLL. And the center of laser spot can be achieved by gradation transformation, binarization and area filter in turn. The software system can set CCD, detect the off-axis paraboloid reflector, measure the parallelity of transmitting axis and aiming axis and control the attenuation device. The hardware system selects SAA7111A, a programmable vedio decoding chip, to perform A/D conversion. FIFO (first-in first-out) is selected as buffer.USB bus is used to transmit data to PC. The three-light-axis parallelity can be achieved according to the position bias between them. The device based on this method has been already used. The application proves this method has high precision, speediness and automatization.

    Destructive natural disasters such as earthquakes and tsunamis have occurred frequently in the world. For instance, 2004 Sumatra Earthquake in Indonesia, 2008 Wenchuan Earthquake in China, 2010 Chile Earthquake and 2011 Tohoku Earthquake in Japan etc., these earthquakes generated very severe damages. For the reduction and mitigation of damages by destructive natural disasters, early detection of natural disasters and speedy and proper evacuations are indispensable. And hardware and software developments/preparations for reduction and mitigation of natural disasters are quite important. In Japan, DONET as the real time monitoring system on the ocean floor is developed and deployed around the Nankai trough seismogenic zone southwestern Japan. So, the early detection of earthquakes and tsunamis around the Nankai trough seismogenic zone will be expected by DONET. The integration of the real time data and advanced simulation researches will lead to reduce damages, however, in the resilience society, the resilience methods will be required after disasters. Actually, methods on restorations and revivals are necessary after natural disasters. We would like to propose natural disaster mitigation science for early detections, evacuations and restorations against destructive natural disasters. This means the resilience society. In natural disaster mitigation science, there are lots of research fields such as natural science, engineering, medical treatment, social science and literature/art etc. Especially, natural science, engineering and medical treatment are fundamental research fields for natural disaster mitigation, but social sciences such as sociology, geography and psychology etc. are very important research fields for restorations after natural disasters. Finally, to realize and progress disaster mitigation science, human resource cultivation is indispensable. We already carried out disaster mitigation science under `new disaster mitigation research project on Mega

    Full Text Available The article addresses the problems of the conceptual apparatus of innovation as an economic category, the basic aspects of the innovation activities of the organization, conducted a historical analysis of the evolution of the concept of “innovation”. Previously, it was customary to assume that the process is driven by innovative organizations that develop and offer innovations, today; society has come to the realization of the consumer – the driving force of innovation development. All the analyzed theory can be combined approach to “innovation” consideration in terms of business benefits. The authors of the twentieth millennium write about innovation because of constant movement and change of the market economy, which leads to the speedy preparation of pre – businessman benefits by satisfying needs. Based on the foregoing, we believe that it is necessary to distinguish the concept of “invention” and “innovation”. Under the invention, we mean a new technical solution. An innovation is the initiation of the idea of innovation as a way out of intellectual activity, i. e., a new product, a new method, a new solution. By innovation author implies innovation, ie an invention or innovation after the commercialization process, demanded and implemented - introduction to the market, has successfully sold and which brought a profit. Treat innovation as the development process is not entirely correct, because not every development is innovation, development or process cannot be measured qualitatively, and it is impossible to talk about innovation as a result of the process will not be launched on the market and consumer demand there as the final result of the innovative activity of the enterprise. Because such an interpretation does not meet the scientific and practical needs of economic systems, the resolution of the identified contradictions, perhaps for the demarcation of the terms “innovation” and “innovation process

  2. Stigma Sensitivity and the Duration of Temporary Closure Are Affected by Pollinator Identity in Mazus miquelii (Phrymaceae, a Species with Bilobed Stigma

    Full Text Available A sensitive bilobed stigma is thought to assure reproduction, avoid selfing and promote outcrossing. In addition, it may also play a role in pollinator selection since only pollinators with the appropriate body size can trigger this mechanism. However, no experimental study has investigated how the sensitive stigma responds to different pollinators and its potential effects on pollination. Mazus miquelii (Phrymaceae, a plant with a bilobed stigma was studied to investigate the relationship between stigma behaviors and its multiple insect pollinators. The reaction time of stigma closure after touched, duration of temporary closure, and factors determining permanent closure of the stigma were studied when flowers were exposed to different visitors and conducted with hand pollination. Manual stimulation was also used to detect the potential differences in stigmas when touched with different degrees of external forces. Results indicated that, compared to pollinators with a small body size, larger pollinators transferred more pollen grains to the stigma, causing a rapid stigma response and resulting in a higher percentage of permanent closures. Duration of temporary closure was negatively correlated with the speed of stigma closure; a stigma that closed more rapidly reopened more slowly. Manual stimulation showed that reaction time of stigma closure was likely a response to external mechanical forces. Hand pollination treatments revealed that the permanent closure of a stigma was determined by the size of stigmatic pollen load. For large pollinators, the speedy reaction of the stigma might help to reduce pollen loss, enhance pollen germination and avoid obstructing pollen export. Stigmas showed low sensitivity when touched by inferior pollinators, which may have increased the possibility of pollen deposition by subsequent visits. Therefore, the stigma behavior in M. miquelii is likely a mechanism of pollinator selection to maximize pollination

    Overeating and obesity are associated with impulsivity. In studies among patients with a substance use disorder, impulsivity was found to be associated with substance-related attentional bias. This study examined whether obesity, impulsivity and food craving are associated with an attentional bias for high-calorie food. Obese (n = 185, mean BMI = 38.18 ± 6.17) and matched healthy-weight (n = 134, mean BMI = 22.35 ± 1.63) men (27.9%) and women (72.1%), aged 18-45 years, took part in the study. Participants were tested on several self-report and behavioral measures of impulsivity (i.e., response inhibition and reward sensitivity) and self-reported trait craving. In addition, they performed a visual search task to measure attentional bias for high- and low-caloric foods. Self-reported impulsivity influenced the relationship between weight status and detection speed of high- and low-caloric food items: High-impulsive participants with obesity were significantly faster than high-impulsive healthy-weight participants in detecting a high-caloric food item among neutral items, whereas no such difference was observed among low-impulsive participants. No significant effects were found on low-caloric food items, for trait craving or any of the behavioral measures of impulsivity. Self-reported impulsivity, but not trait craving or behavioral measures of impulsivity, is associated with an attentional bias for high-caloric foods, but only in people with obesity. It is in particular the speedy detection of high-caloric foods in the environment that characterizes the impulsive person with obesity, which in turn may cause risky eating patterns in a society were high-caloric food is overly present.

    Full Text Available For Russia as a democratic federal state, federal relations are basic for the whole social development of the country. In this regard, it is particularly important to strike a balance between centripetal and centrifugal forces. The analysis of budget indicators presented in the article revealed the growing process of centralization, which enabled to conclude the low efficiency of the modern mechanism of tax allocation and its non-compliance to the principles of fiscal federalism. The growing budget crisis of the regions and the long-felt need of the structural reforming of Russian tax system require speedy implementation of internal reserves. Among these provisions, Russian scientists including the Institute of Socio-Economic Development of Territories of the Russian Academy of Sciences see the urgent need of the structural reform of the tax system in the Russian Federation. The results of the scientific search for answers to the questions of how and what it is expedient to amend, supplement, and delete in the Russian tax system are presented. In order to create incentives for the territorial authorities to increase the income, the algorithm of the distribution of tax revenue between the federal and regional budgets is developed on the basis of the estimations of the ratio of the volume of tax revenues collected in the region and received by the federal budget. Experimental calculations on the example of 83 subjects of the Russian Federation have identified the existing provisions of tax revenue growth in 36 subjects that could increase revenues by 2 –12 %. The authors have proposed a set of key measures for optimizing the tax incentive policies, involving the development of selective and differential principles of tax incentives, the introduction of compensatory forms of the loss of income as a result of benefits. The main measures to enhance the collection of regional and local property taxes are systematized.

Thus, by exploiting competencies learned by observation, individuals with Williams syndrome detected the visuo-motor sequence, putting into action the appropriate procedural strategies. Conversely, their impaired performances in the exercise phases appeared linked to impaired spatial working memory, while their deficits in automatization phases to deficits in processes increasing efficiency and speed of the response. Overall, observational experience was advantageous for

    The incidences of seizures and epilepsy in the population show a peak after 60 years of age. Due to the lack of reported clinical aspects of seizure and epilepsy in the older patients in our region in Iran, this study was conducted to describe the clinical manifestation, etiology, differential diagnosis, and epilepsy subtypes of epilepsy and seizure. A cross-sectional retrospective study was performed on all consecutively elderly seizure and epilepsy patients, referred to the Epilepsy Association in the city of Qom, Iran over a 10-year period. A total of 466 patients aged >60 years were admitted. 31 % of the patients had epilepsy or seizure and 69 % of them had non-epileptic events. The most prevalent differential diagnoses in the beginning were syncope and cardiovascular disorders. The most frequent clinical symptom of epilepsy was generalized tonic-clonic seizures (75 %). The most common cause of seizure was systemic metabolic disorder (27 %). In epileptic elderly patients, no cause was ascertained for 38 % and the most frequently observed pathological factors were cerebrovascular diseases, which accounted for 24 %. The most common type of epileptic seizure was generalized epileptic seizures (75 %). 10 % of elderly epileptic patients suffered from status epilepticus, which was primarily caused by anoxia. Despite the rising rate and potentially profound physical and psychosocial effects of seizures and epilepsy, these disorders have received surprisingly little research focus and attention in Iran. Referring older patients to a specialist or a specialist epilepsy center allows speedy assessment, appropriate investigation and treatment, and less likely to miss the diagnosis.

  7. EXO70C2 is a key regulatory factor for optimal tip growth of pollen

    The exocyst, an eukaryotic tethering complex, co-regulates targeted exocytosis as an effector of small GTPases in polarized cell growth. In land plants, several exocyst subunits are encoded by double or triple paralogs, culminating in tens of EXO70 paralogs. Out of 23 Arabidopsis EXO70 isoforms, we analyzed seven isoforms expressed in pollen. Genetic and microscopic analyses of single mutants in EXO70A2, C1, C2, F1, H3, H5, and H6 genes revealed that only a loss-of-function EXO70C2 allele resulted in a significant male-specific transmission defect (segregation 40%:51%:9%) due to aberrant pollen tube growth. Mutant pollen tubes grown in vitro exhibited enhanced growth rate and a decreased thickness of the tip cell wall, causing tip bursts. However, exo70C2 pollen tubes could frequently recover and restart their speedy elongation, resulting in a repetitive stop-and-go growth dynamics. A pollen-specific depletion of the closest paralog, EXO70C1, using ami-RNA in the exo70C2 mutant background resulted in a complete pollen-specific transmission defect, suggesting redundant functions of EXO70C1 and EXO70C2. Both EXO70C1 and EXO70C2, GFP-tagged and expressed under their native promoters, localized in the cytoplasm of pollen grains, pollen tubes, and also root trichoblast cells. Expression of EXO70C2-GFP complemented aberrant growth of exo70C2 pollen tubes. The absent EXO70C2 interactions with core exocyst subunits in the yeast two-hybrid assay, cytoplasmic localization, and genetic effect suggest an unconventional EXO70 function possibly as a regulator of exocytosis outside the exocyst complex. In conclusion, EXO70C2 is a novel factor contributing to the regulation of optimal tip growth of Arabidopsis pollen tubes.

    The nutritional status of both women and men before conception has profound implications for the growth, development, and long-term health of their offspring. Evidence of the effectiveness of preconception interventions for improving outcomes for mothers and babies is scarce. However, given the large potential health return, and relatively low costs and risk of harm, research into potential interventions is warranted. We identified three promising strategies for intervention that are likely to be scalable and have positive effects on a range of health outcomes: supplementation and fortification; cash transfers and incentives; and behaviour change interventions. On the basis of these strategies, we suggest a model specifying pathways to effect. Pathways are incorporated into a life-course framework using individual motivation and receptiveness at different preconception action phases, to guide design and targeting of preconception interventions. Interventions for individuals not planning immediate pregnancy take advantage of settings and implementation platforms outside the maternal and child health arena, since this group is unlikely to be engaged with maternal health services. Interventions to improve women's nutritional status and health behaviours at all preconception action phases should consider social and environmental determinants, to avoid exacerbating health and gender inequalities, and be underpinned by a social movement that touches the whole population. We propose a dual strategy that targets specific groups actively planning a pregnancy, while improving the health of the population more broadly. Modern marketing techniques could be used to promote a social movement based on an emotional and symbolic connection between improved preconception maternal health and nutrition, and offspring health. We suggest that speedy and scalable benefits to public health might be achieved through strategic engagement with the private sector. Political theory supports

  9. Effective assimilation of global precipitation: simulation experiments

    Full Text Available Past attempts to assimilate precipitation by nudging or variational methods have succeeded in forcing the model precipitation to be close to the observed values. However, the model forecasts tend to lose their additional skill after a few forecast hours. In this study, a local ensemble transform Kalman filter (LETKF is used to effectively assimilate precipitation by allowing ensemble members with better precipitation to receive higher weights in the analysis. In addition, two other changes in the precipitation assimilation process are found to alleviate the problems related to the non-Gaussianity of the precipitation variable: (a transform the precipitation variable into a Gaussian distribution based on its climatological distribution (an approach that could also be used in the assimilation of other non-Gaussian observations and (b only assimilate precipitation at the location where at least some ensemble members have precipitation. Unlike many current approaches, both positive and zero rain observations are assimilated effectively. Observing system simulation experiments (OSSEs are conducted using the Simplified Parametrisations, primitivE-Equation DYnamics (SPEEDY model, a simplified but realistic general circulation model. When uniformly and globally distributed observations of precipitation are assimilated in addition to rawinsonde observations, both the analyses and the medium-range forecasts of all model variables, including precipitation, are significantly improved as compared to only assimilating rawinsonde observations. The effect of precipitation assimilation on the analyses is retained on the medium-range forecasts and is larger in the Southern Hemisphere (SH than that in the Northern Hemisphere (NH because the NH analyses are already made more accurate by the denser rawinsonde stations. These improvements are much reduced when only the moisture field is modified by the precipitation observations. Both the Gaussian transformation and

    The aim of this prospective clinical study was to evaluate the 3-year outcome of fixed partial prostheses supported by implants with immediate provisionalization without occlusal contacts inserted in predominantly soft bone with flap and flapless protocols. Forty-one patients partially rehabilitated with 72 NobelSpeedy implants (51 maxillary; 21 mandibular) were consecutively included and treated with a flapless surgical protocol (n = 20 patients; 32 implants) and flapped surgical protocol (n = 21 patients; 40 implants). Primary outcome measure was implant survival; secondary outcome measures were marginal bone resorption (comparing the bone levels at 1 and 3 years with baseline) and the incidence of biological, mechanical, and esthetic complications. Survival was computed through life tables; descriptive statistics were applied to the remaining variables of interest. Eight patients with eight implants dropped out of the study. One implant failed in one patient (flapless group) giving an overall cumulative survival rate (CSR) of 98.6%. No failures were noted with the flapped protocol (CSR 100%), while for the implants placed with the flapless surgical technique, a 96.9% CSR was registered. The overall average marginal bone resorption at 3 years was 1.37 mm (SD = 0.94 mm), with 1.14 mm (SD = 0.49 mm) and 1.60 mm (SD = 1.22 mm) for the flap and flapless groups, respectively. Mechanical complications occurred in nine patients (n = 5 patients in the flapless group; n = 4 patients in the flap group). Implant infection was registered in three implants and three patients (flapless group), who exhibited inadequate oral hygiene levels. Partial edentulism rehabilitation through immediate provisionalization fixed prosthesis supported by dental implants inserted through flap or flapless surgical techniques in areas of predominantly soft bone was viable at 3 years of follow-up. The limitations and risks of the "free-hand" method in flapless surgery should be considered when

    Full Text Available Background  Apnea is one of the most common problems in preterm neonates. This study aimed to evaluate the effectiveness of aromatherapy on the reduction of apnea, bradycardia, and Pulse Oximetry (SPO2 in premature infants. Materials and Methods In a clinical trial study, 60 preterm neonates randomly divided in two groups and exposed to aromatherapy with Rosa damascenes distillate or distilled water beside the routine treatment. In experimental group, two drops of 10% Rosa damascenes distillate was dropped on the pad eye in second day of birth at 6 Am. The intervention was repeated in 9 AM, 12 Am, 15 PM and 18 PM hours. A same condition applied for control group and distilled water was dropped on the pad eye. The number of apnea attacks, bradycardia and decrease in SpO2 compared between two groups using chi-square test, independent t-test and repeated measure test. Results The overall apnea attacks, bradycardia, and SPO2 in tree studied days were lower in intervention group than control group (0.47±0.13 vs. 2.6±0.41, 0.47±0.13 vs. 2.56±0.41 and 0.70±0.17 vs. 2.77±0.21, respectively. In addition, the repeated measurement test showed that the mean number of apnea attacks, decrease in heart pulse rate, and decrease in SpO2 was statistically lower in intervention group with aromatherapy than controls in first, second, third and sum of three days (P< 0.05. Conclusion Aromatherapy with Rosa damascenes distillate can reduce more and speedy the occurrence of apnea attacks, bradycardia and SPO2 in premature infants, along with other routine treatment.

    Pregnant NMRI mice were X-irradiated with 50, 100 and 200 R, respectively, on the twelfth gestational day. The brains of their offspring were weighed and examined for acetylcholinesterase and Na,K-ATPase activities from birth until the 64th postnatal day. The postnatal brain weights were influenced by the prenatal irradiation in a dose-dependent manner. At birth the brains of the treated animals weighed less than those of the controls. After a limited period of restitution (postnatal days 3 to 10), weights fell again, as compared to the controls, and persisted at subnormal levels. This was assumed to be a sequel of surplus neuron cell formation and their speedy degradation as soon as neuronal function had been established. The curves of the activites (per gram of brain tissue) of acetylcholinesterase as well as Na,K-ATPase showed oscillating compensatory responses to the prenatal irradiation. Activities were preferentially found at supernormal levels, the oscillation lasting as long as the restitution period of the brain weights. With the 50 R and 100 R groups, enzyme activities were steadily above the control levels from the 16th until the 48th day after birth. On the 64th postnatal day all enzyme activities but one (200 R, Na,K-ATPase) had returned to the control levels. Oscillating responses to prenatal X-irradiation have been described for the DNA-synthesis in livers and brains of mice during the first three postnatal weeks. From this perspective, our results are discussed as the outcome of radiation-induced alterations in genome activity. (orig.) [de

  13. "Like a trip to McDonalds": a grounded theory study of patient experiences of day surgery.

    The amount and complexity of (ambulatory) day surgery is rapidly expanding internationally. Nurses have a responsibility to provide quality care for day surgery patients. To do this they must understand all aspects of the patient experience. There is dearth of research into day surgery using a sociological frame of reference. The study investigated patients' experiences of day surgery using a sociological frame of reference. A qualitative study using the grounded theory approach was used. The study was based in two day surgery units in two urban public hospitals in the United Kingdom. 145 patients aged 18-70 years and 100 carers were purposely selected from the orthopaedic, ear nose and throat and general surgical lists. They were all English speaking and were of varied socio-economic background. The data was collected from 2004 to 2006. Semi-structured interviews were conducted on three occasions: before surgery, 48 h following surgery and one month following discharge. Permission was received from the Local Research Ethics Committee. Analysis of the data involved line-by-line analysis, compilation of key words and phrases (codes) and constant comparison of the codes until categories emerged. Patients liked day surgery and placed it within the wider societal context of efficiency and speed. Time was a major issue for them. They wished surgery, like all other aspects of their life to be a speedy process. They likened it to a McDonald's experience with its emphasis on speed, predictability and control. This study throws new light on patient experiences and offers an understanding of day surgery against a western culture which emphasises the importance of speed and efficiency. It is a popular choice for patients but at times it can be seen to be a mechanistic way of providing care. The implications for nurses to provide education and information to add to the quality of the patient experience are discussed. Copyright © 2010 Elsevier Ltd. All rights reserved.

    Breast cancer is the leading cause of cancer morbidity among Shanghai and Hong Kong women, which contributes to 20-25% of new female cancer incidents. This study aimed to describe the temporal trend of breast cancer and interpret the potential effects on the observed secular trends. Cancer incident data were obtained from the cancer registries. Age-standardized incidence rate was computed by the direct method using the World population of 2000. Average annual percentage change (AAPC) in incidence rate was estimated by the Joinpoint regression. Age, period and cohort effects were assessed by using a log-linear model with Poisson regression. During 1976-2009, an increasing trend of breast cancer incidence was observed, with an AAPC of 1.73 [95% confidence interval (CI): 1.54-1.92)] for women in Hong Kong and 2.83 (95% CI, 2.26-3.40) in Shanghai. Greater upward trends were revealed in Shanghai women aged 50 years old or above (AAPC = 3.09; 95% CI, 1.48-4.73). Using age at 50 years old as cut-point, strong birth cohort effects were shown in both pre- and post-menopausal women, though a more remarkable effect was suggested in Shanghai post-menopausal women. No evidence for a period effect was indicated. Incidence rate of breast cancer has been more speedy in Shanghai post-menopausal women than that of the Hong Kong women over the past 30 years. Decreased birth rate and increasing environmental exposures (e.g., light-at-night) over successive generations may have constituted major impacts on the birth cohort effects, especially for the post-menopausal breast cancer; further analytic studies are warranted.

    Sedentary behaviours (SB) are highly prevalent in young people and may be adversely associated with physical and mental health. Understanding of the modifiable determinants of SB is necessary to inform the design of behaviour change interventions but much of the existing research is cross-sectional and focussed upon screen-based behaviours. To examine the social, psychological and environmental determinants of change in children's objectively measured sedentary time from age 11 to 14 years. Data are from the second (2008) and third (2011) waves of assessment in the Sport, Physical Activity, and Eating Behaviour: Environmental Determinants in Young People (SPEEDY) study, conducted in the county of Norfolk, United Kingdom. Longitudinal data on accelerometer assessed sedentary time were available for 316 (53.5% female, 11.2±0.3 years at baseline) and 264 children after-school and at the weekend respectively. Information on 14 candidate determinants, including school travel mode and electronic media ownership, was self-reported. Change in the proportion of registered time spent sedentary was used as the outcome variable in cross-classified linear regression models, adjusted for age, sex, body mass index and baseline sedentary time. Simple and multiple models were run and interactions with sex explored. Daily sedentary time increased by 30-40 minutes after-school and at the weekend from baseline to follow-up. Participants who travelled to school by cycle exhibited smaller increases in after-school sedentary time (beta; 95%CI for change in % time spent sedentary: -3.3;-6.7,-0.07). No significant determinants of change in weekend sedentary time were identified. Time spent sedentary increased during the three-year duration of follow-up but few of the variables examined were significantly associated with changes in sedentary time. Children's mode of school travel may influence changes in their sedentary time over this period and should be examined further, alongside

    As for the relationship between 'science and technology' and society, a huge gap exists between the question and expectation toward sociology given by ordinary people and the actual state of sociology. Sociology of science tries to provide a platform for transforming this kind of situation. What is currently talked about the Fukushima nuclear accident would be required to be revised according to the revealed fact in the future. Although there is such a limitation, what should be done at present is described from the viewpoint of sociology of science. The structure disaster is taken up from the viewpoint for not alienating the Fukushima accident, and the following five characteristics are involved in a complex manner. (1) To preserve precedent problems even if the precedents are wrong. (2) The complexity and mutual dependency of system amplify problems. (3) The informal norms of small groups hollow the official norms over a long term. (4) Stopgap measures based on ad hock presumption proliferate in face of measures against problems. (5) The secrecy principle obscures the whereabouts of responsibility throughout sectors. As for the way to operate SPEEDI (system for prediction of environmental emergency dose information) immediately after the Fukushima accident, this paper discusses the ideal way of responsibility attribution in consideration of the implication of structural disaster. In order not to invite such social conditions again as causing a serious accident due to the easy belief of unsafe conditions as safe, it is essential to create a mechanism that everyone publicly shares the issues associated with unlimited liability by means of the re-designing of the system.

    1996-01-01

    All activities in the field of radiation protection are based on the Euratom Treaty. Both the Single European Act and the Maastricht Treaty leave the Euratom Treaty practically unchanged. So far the Commission has considered that the provisions of the Euratom Treaty, in particular its Chapter III - health and safety, give enough competence to the Community, and an acceptable level of safety is reached through the carrying out of a number of duties incumbent on the Community institutions and the Member States. It is to be noted that the task of the Euratom Treaty, as set out in its Article 1, is to c reate the conditions necessary for the speedy establishment and growth of nuclear industries . However, for several years, the Commission has recognised that the major contribution it could make to achieve the task of the Treaty is by ensuring a high level of protection and safety in all activities concerned with radioactivity and nuclear energy. The following is a list of the major provisions of the Treaty on which activities in the field of radiation protection are based.Article 2b) Euratom Treaty requires the Community to establish uniform safety standards to protect the health of workers and of the general public and ensure that they are applied. The meaning and the procedure for such standards is given in Articles 30-32 of the Treaty. Article 33) of the Euratom Treaty sets out that draft national regulations on radiation protection are communicated to the Commission which may wish to issue recommendations within three months. Article 35 imposes on Member States the establishment of facilities to carry out the environmental monitoring of radioactivity and to ensure compliance with the basic safety standards. It also gives the Commission the right of access to such facilities. Article 37 requires Member States to provide the Commission with such general data on any plan for the disposal of radioactive waste as will make it possible to evaluate its possible impact on

    Background Poor communication between in-hours and out-of-hours (OoH) general practitioners (GPs) causes unwanted admissions to hospital of patients who want to die at home Setting A GP OoH service in West London (London Central and West Unscheduled Care Service) used by 159 general practices from four primary care trusts Question What helps to avoid hospital admission of patients who want to die at home when a crisis occurs in the OoH period? Methods Whole system participatory action research, with four stages: 1. engage stakeholders; 2. understand the initial situation; 3. re-design the system; 4. action for change Results The following help to avoid undesirable hospital admission of a dying person who has a crisis in the OoH period: 1. a register of vulnerable adults; 2. records at home; 3. key worker(s); 4. home interventions; 5. day-time practitioner communication; 6. a development and governance group; 7. speedy discharge from hospital; 8. decision support for OoH GPs. Discussion This project revealed a useful set of policies to help avoid unnecessary OoH admission to hospital, especially improved communication between day-time GPs and OoH GPs. The approach combined whole system participatory action research with systems modelling and this helped the issues to be revealed quickly and cheaply. Furthermore, including leaders from partner organisations at each stage of the inquiry has encouraged shared purpose and produced champions to move forward the project recommendations. Some changes have already happened.

  20. Formulaic language in cortical and subcortical disease: Evidence of the dual process model.

    2014-04-01

    Full Text Available Introduction: It is known that an intact cortical left hemisphere is crucial for language production. Recently, more credit is given to the right hemisphere and subcortical areas in the production of non-novel language, including formulaic language. John Hughlings Jackson (1874/1958, first described how propositional and non-propositional speech are differentially affected by neural impairment. Non-propositional language is often preserved following left hemisphere stroke even when aphasia is present (Code, 1982; Sidtis et al., 2009; Van Lancker Sidtis & Postman, 2006. With right hemisphere and subcortical stroke, formulaic language is reduced (Sidtis et al., 2009; Van Lancker Sidtis & Postman, 2006; Speedie et al., 1993. The dual process model of language competence states that propositional and non-propositional speech are processed differently in the brain, with novel speech controlled by the left hemisphere, and a right hemisphere/subcortical circuit modulating formulaic language (Van Lancker Sidtis, 2004; 2012. Two studies of formulaic language will be presented as further evidence of the dual process model: a study of formulaic language in Alzheimer’s disease, and a study of recited speech in Parkinson’s disease. Formulaic language includes overlearned words, phrases or longer linguistic units that are known to the native speaker, occur naturally in discourse, and are important for normal social interaction (Fillmore, 1979; Pawley & Syder, 1983; Van Lancker, 1988; Van Lancker Sidtis, 2004; Wray, 2002. Formulaic expressions include conversational speech formulas, idioms, proverbs, expletives, pause fillers, discourse elements, and sentence stems (stereotyped sentence-initials. Longer units of linguistic material, such as prayers, rhymes, and poems, termed recited speech, is another subtype of formulaic language that is learned in childhood and recited periodically throughout life.

    The SPIDR (Speedy PIxel Detector Readout) system is a flexible general-purpose readout platform that can be easily adapted to test and characterize new and existing detector readout ASICs. It is originally designed for the readout of pixel ASICs from the Medipix/Timepix family, but other types of ASICs or front-end circuits can be read out as well. The SPIDR system consists of an FPGA board with memory and various communication interfaces, FPGA firmware, CPU subsystem and an API library on the PC . The FPGA firmware can be adapted to read out other ASICs by re-using IP blocks. The available IP blocks include a UDP packet builder, 1 and 10 Gigabit Ethernet MAC's and a 'soft core' CPU . Currently the firmware is targeted at the Xilinx VC707 development board and at a custom board called Compact-SPIDR . The firmware can easily be ported to other Xilinx 7 series and ultra scale FPGAs. The gap between an ASIC and the data acquisition back-end is bridged by the SPIDR system. Using the high pin count VITA 57 FPGA Mezzanine Card (FMC) connector only a simple chip carrier PCB is required. A 1 and a 10 Gigabit Ethernet interface handle the connection to the back-end. These can be used simultaneously for high-speed data and configuration over separate channels. In addition to the FMC connector, configurable inputs and outputs are available for synchronization with other detectors. A high resolution (≈ 27 ps bin size) Time to Digital converter is provided for time stamping events in the detector. The SPIDR system is frequently used as readout for the Medipix3 and Timepix3 ASICs. Using the 10 Gigabit Ethernet interface it is possible to read out a single chip at full bandwidth or up to 12 chips at a reduced rate. Another recent application is the test-bed for the VeloPix ASIC, which is developed for the Vertex Detector of the LHCb experiment. In this case the SPIDR system processes the 20 Gbps scrambled data stream from the VeloPix and distributes it over four

    Full Text Available Sleep, physical activity, screen time and dietary behaviours influence health during childhood, but few studies have looked at all of these behaviours simultaneously and previous research has relied predominantly on self- or proxy-reports of physical activity and food frequency questionnaires for the assessment of diet.To assess the prevalence and clustering of health behaviours and examine the socio-demographic characteristics of children that fail to meet multiple health behaviour guidelines.Data are from the Sport, Physical activity and Eating behaviour: Environmental Determinants in Young people (SPEEDY study. Participants (n = 1472, 42.9% male were dichotomized based on whether or not they met public health guidelines for accelerometer-assessed physical activity, diet-diary assessed fruit/vegetable intake and fat/non-milk extrinsic sugar (NMES intake, and self-reported screen time and sleep duration. Behavioural clustering was assessed using an observed over expected ratio (O/E. Socio-demographic characteristics of participants that failed to meet multiple health behaviour guidelines were examined using ordinal logistic regression.

    Assimilating precipitation observations by modifying the moisture and sometimes temperature profiles has been shown successful in forcing the model precipitation to be close to the observed precipitation, but only while the assimilation is taking place. After the forecast start, the model tends to "forget" the assimilation changes and lose their extra skill after few forecast hours. This suggests that this approach is not an efficient way to modify the potential vorticity field, since this is the variable that the model would remember. In this study, the ensemble Kalman filter (EnKF) method is used to effectively change the potential vorticity field by allowing ensemble members with better precipitation to receive higher weights. In addition to using an EnKF, two other changes in the precipitation assimilation process are proposed to solve the problems related to the highly non-Gaussian nature of the precipitation variable: a) transform precipitation into a Gaussian distribution based on its climatological distribution, and b) only assimilate precipitation at the location where some ensemble members have positive precipitation. The idea is first tested by the observing system simulation experiments (OSSEs) using SPEEDY, a simplified but realistic general circulation model. When the global precipitation is assimilated in addition to conventional rawinsonde observations, both the analyses and the medium range forecasts are significantly improved as compared to only having rawinsonde observations. The improvement is much reduced when only modifying the moisture field with the same approach, which shows the importance of the error covariance between precipitation and all other model variables. The effect of precipitation assimilation is larger in the Southern Hemisphere than that in the Northern Hemisphere because the Northern Hemisphere analyses are already accurate as a result of denser rawinsonde stations. Assimilation of precipitation using a more comprehensive

    Total knee arthroplasty (TKA) has become the most preferred procedure by patients for the relief of pain caused by knee osteoarthritis. TKA patients aim a speedy recovery after the surgery. Joint mobilization techniques for rehabilitation have been widely used to relieve pain and improve joint mobility. However, relevant randomized controlled trials showing the curative effect of these techniques remain lacking to date. Accordingly, this study aims to investigate whether joint mobilization techniques are valid for primary TKA. We will manage a single-blind, prospective, randomized, controlled trial of 120 patients with unilateral TKA. Patients will be randomized into an intervention group, a physical modality therapy group, and a usual care group. The intervention group will undergo joint mobilization manipulation treatment once a day and regular training twice a day for a month. The physical modality therapy group will undergo physical therapy once a day and regular training twice a day for a month. The usual care group will perform regular training twice a day for a month. Primary outcome measures will be based on the visual analog scale, the knee joint Hospital for Special Surgery score, range of motion, surrounded degree, and adverse effect. Secondary indicators will include manual muscle testing, 36-Item Short Form Health Survey, Berg Balance Scale function evaluation, Pittsburgh Sleep Quality Index, proprioception, and muscle morphology. We will direct intention-to-treat analysis if a subject withdraws from the trial. The important features of this trial for joint mobilization techniques in primary TKA are randomization procedures, single-blind, large sample size, and standardized protocol. This study aims to investigate whether joint mobilization techniques are effective for early TKA patients. The result of this study may serve as a guide for TKA patients, medical personnel, and healthcare decision makers. It has been registered at http

    Over the last 25 years, a tremendous progress has been made in the Earth science space-based remote sensing observations, technologies and algorithms. Such advancements have improved the predictability by providing lead-time and accuracy of forecast in weather, climate, natural hazards, and natural resources. It has further reduced or bounded the overall uncertainties by partially improving our understanding of planet Earth as an integrated system that is governed by non-linear and chaotic behavior. Many countries such US, European Community, Japan, China and others have invested billions of dollars in developing and launching space-based assets in the low earth (LEO) and geostationary (GEO) orbits. However, the wealth of this scientific knowledge that has potential of extracting monumental socio-economic benefits from such large investments have been slow in reaching the public and decision makers. For instance, there are a number of areas such as energy forecasting, aviation safety, agricultural competitiveness, disaster management, homeland security, air quality and public health, which can directly take advantage. Nevertheless, we all live in a global economy that depends on access to the best available Earth Science information for all inhabitants of this planet. This paper surveys and examines a number such applications in terms of their architecture, maturity and economic applicability as they apply to the societal needs. A detailed analysis is also presented of various challenges and issues that pertain to a number of areas such as: (1) difficulties in making a speedy transition of data and information from observations and models to relevant Decision Support Systems (DSS) or tools, (2) data and models inter-operability issues, (3) limitations of spatial, spectral and temporal resolution,(4) communication limitations as dictated by the availability of image processing and data compression techniques. Additionally, the most critical element amongst all is

    Background The school journey may make an important contribution to children’s physical activity and provide exposure to food and physical activity environments. Typically, Geographic Information Systems (GIS) have been used to model assumed routes to school in studies, but these may differ from those actually chosen. We aimed to identify the characteristics of children and their environments that make the modelled route more or less representative of that actually taken. We compared modelled GIS routes and actual Global Positioning Systems (GPS) measured routes in a free-living sample of children using varying travel modes. Methods Participants were 175 13-14 yr old children taking part in the Sport, Physical activity and Eating behaviour: Environmental Determinants in Young people (SPEEDY) study who wore GPS units for up to 7 days. Actual routes to/from school were extracted from GPS data, and shortest routes between home and school along a road network were modelled in a GIS. Differences between them were assessed according to length, percentage overlap, and food outlet exposure using multilevel regression models. Results GIS routes underestimated route length by 21.0% overall, ranging from 6.1% among walkers to 23.2% for bus users. Among pedestrians food outlet exposure was overestimated by GIS routes by 25.4%. Certain characteristics of children and their neighbourhoods that improved the concordance between GIS and GPS route length and overlap were identified. Living in a village raised the odds of increased differences in length (odds ratio (OR) 3.36 (1.32-8.58)), while attending a more urban school raised the odds of increased percentage overlap (OR 3.98 (1.49-10.63)). However none were found for food outlet exposure. Journeys home from school increased the difference between GIS and GPS routes in terms of food outlet exposure, and this measure showed considerable within-person variation. Conclusions GIS modelled routes between home and school were not

  12. Brexit, Euratom and nuclear proliferation

    2016-01-01

    One of the issues absent from the academic (and public) debate on the United Kingdom's (UK) referendum vote to withdraw from the European Union (EU) (commonly referred to as 'Brexit') is what will happen to the UK's membership in the European Atomic Energy Community (Euratom). The Euratom Treaty was signed in Rome in 1957, together with the European Economic Community (EEC) Treaty. It was concluded for an unlimited period and it establishes a Community that has a separate legal personality from the EU. Thus, the EU and Euratom form two separate, although closely linked entities. Euratom's principal mission is related to the economy, tasked with 'creating the conditions necessary for the speedy establishment and growth of nuclear industries'; in other words, to promote the nuclear industry. This reflects the high expectations for nuclear energy in the 1950's. Some even believed that the development of nuclear energy would trigger an industrial revolution; however, Euratom only came to play a minor role in the European integration process. Despite this, the Euratom Treaty has remained, almost unchanged, since its adoption and is still frequently applied, although it is unclear to what extent it has boosted the nuclear industry. This article has a two-fold purpose. The first purpose is to address the constitutional issue of 'partial membership'. All EU member states are also members of Euratom. It has always been assumed that with membership in the EU also comes a membership in Euratom. But, what about withdrawal? What are the arguments for 'partial membership'? The second purpose of this article is to shed light on some implications of Brexit as it relates to Euratom. The most serious consequences are perhaps found in the area of nuclear non-proliferation. The United Kingdom is one of two nuclear weapon states in the EU (France being the other one). Withdrawal from Euratom means withdrawal from its control system, the system of so-called nuclear safeguards. Under

    A battery-operated, atmospheric pressure, self-igniting, planar geometry Ar-H(2) microplasma for elemental analysis of liquid microsamples is described. The inexpensive microplasma device (MPD) fabricated for this work was a hybrid plastic-quartz structure that was formed on chips with an area (roughly) equal to that of a small-sized postage stamp (MPD footprint, 12.5-mm width by 38-mm length). Plastic substrates were chosen due to their low cost, for rapid prototyping purposes, and for a speedy microplasma device evaluation. To enhance portability, the microplasma was operated from an 18-V rechargeable battery. To facilitate portability even further, it was demonstrated that the battery can be recharged by a portable solar panel. The battery-supplied dc voltage was converted to a high-voltage ac. The ~750-μm (diameter) and 12-mm (long) Ar-H(2) (3% H(2)) microplasma was formed by applying the high-voltage ac between two needle electrodes. Spectral interference from the electrode materials or from the plastic substrate was not observed. Operating conditions were found to be key to igniting and sustaining a microplasma that was simply "warm" to the touch (thus alleviating the need for cooling or other thermal management) and that had a stable background emission. A small-sized (900 μL internal volume) electrothermal vaporization system (40-W max power) was used for microsample introduction. Microplasma background emission in the spectral region between 200 and 850 nm obtained using a portable fiber-optic spectrometer is reported and the effect of the operating conditions is described. Analyte emission from microliter volumes of dilute single-element standard solutions of Cd, Cu, K, Li, Mg, Mn, Na, Pb, and Zn is documented. The majority of spectral lines observed for the elements tested were from neutral atoms. The relative lack of emission from ion lines simplified the spectra, thus facilitating the use of a portable spectrometer. Despite the relative spectral

    Background Sedentary behaviours (SB) are highly prevalent in young people and may be adversely associated with physical and mental health. Understanding of the modifiable determinants of SB is necessary to inform the design of behaviour change interventions but much of the existing research is cross-sectional and focussed upon screen-based behaviours. Purpose To examine the social, psychological and environmental determinants of change in children’s objectively measured sedentary time from age 11 to 14 years. Methods Data are from the second (2008) and third (2011) waves of assessment in the Sport, Physical Activity, and Eating Behaviour: Environmental Determinants in Young People (SPEEDY) study, conducted in the county of Norfolk, United Kingdom. Longitudinal data on accelerometer assessed sedentary time were available for 316 (53.5% female, 11.2±0.3 years at baseline) and 264 children after-school and at the weekend respectively. Information on 14 candidate determinants, including school travel mode and electronic media ownership, was self-reported. Change in the proportion of registered time spent sedentary was used as the outcome variable in cross-classified linear regression models, adjusted for age, sex, body mass index and baseline sedentary time. Simple and multiple models were run and interactions with sex explored. Results Daily sedentary time increased by 30–40 minutes after-school and at the weekend from baseline to follow-up. Participants who travelled to school by cycle exhibited smaller increases in after-school sedentary time (beta; 95%CI for change in % time spent sedentary: -3.3;-6.7,-0.07). No significant determinants of change in weekend sedentary time were identified. Conclusions Time spent sedentary increased during the three-year duration of follow-up but few of the variables examined were significantly associated with changes in sedentary time. Children’s mode of school travel may influence changes in their sedentary time over this

    To examine the association between diet and physical activity and sedentary behaviours in 9-10-year-old children. A cross-sectional study using data from the SPEEDY (Sport, Physical activity and Eating behaviour: Environmental Determinants in Young People) study undertaken in Norfolk, UK. Data from 4-day food diaries and 7 days of accelerometery were matched on concurrent days. Time spent in moderate-to-vigorous physical activity (MVPA), time spent in sedentary behaviour and various measures of dietary intake were collected. Covariates included age, sex, weight status, family socio-economic status, and energy intake reporting quality. Multivariable regression models, adjusted for clustering of children by school and stratified by sex, were fitted to examine the associations between dietary measures and physical activity and sedentary outcomes. In total, 1317 children (584 boys and 733 girls) provided concurrent data. Boys in the highest quartile of energy percentage from protein spent approximately 6 min [95% confidence interval (CI) 0-12] less in MVPA compared with boys in the lowest quartile. Those in the highest quartiles of fruit and vegetable intake and fruit juice intake had respective average activity counts per minute that were 56 above (95% CI 8-105) and 48 below (95% CI 2-95) those in the lowest quartiles, whilst those in the highest quartile of fizzy drink consumption spent approximately 7 min (95% CI 2-13) more in MVPA and approximately 14 min (95% CI 5-24 min) less in sedentary behaviour. Boys in the highest quartile of savoury snack consumption spent approximately 8 min (95% CI 2-13 min) more in MVPA per day, and approximately 12 min (95% CI 2-23) less in sedentary behaviour. No significant associations were apparent among girls. Few associations were detected, and the directions of those that were apparent were mainly counterintuitive. The extent to which this reflects a true lack of association or is associated with the measurement methods used for

    The behavior of metastable water at low temperatures is unusual. The isothermal compressibility, the isobaric heat capacity, and the magnitude of the thermal expansion coefficient increase sharply upon supercooling, and structural relaxation becomes extremely sluggish at temperatures far above the glass transition(Angell, C.A., Annu. Rev. Phys. Chem., 34, 593, 1983)(Debenedetti, P.G., Metastable Liquids. Concepts and Principles, Princeton University Press, 1996). Water has two distinct glassy phases, low- and high-density amorphous ice (LDA, HDA). The transition between LDA and HDA is accompanied by sharp volume and enthalpy changes, and appears to be first-order(Mishima, O., L.D.Calvert, and E. Whalley, Nature, 314, 76, 1985)(Mishima, O., J. Chem. Phys., 100, 5910, 1994). The understanding of these observations in terms of an underlying global phase behavior remains incomplete(Speedy, R.J., J. Phys. Chem., 86, 982, 1982)(Poole, P.H., F. Sciortino, U. Essman, and H.E. Stanley, Nature, 360, 324, 1992)(Sastry, S., P.G. Debenedetti, F. Sciortino, and H.E. Stanley, Phys. Rev. E, 53, 6144, 1996)(Tanaka, H., Nature, 380, 328, 1996)(Xie, Y., K.F. Ludwig, G. Morales, D.E. Hare, and C.M. Sorensen, Phys. Rev. Lett., 71, 2050, 1993). Microscopic theories and computer simulations suggest several scenarios that can reproduce some experimental observations. Interesting and novel ideas have resulted from this body of theoretical work, such as the possibility of liquid-liquid immiscibility in a pure substance(Poole, P.H., F.Sciortino, T.Grande, H.E. Stanley, and C.A. Angell, Phys. Rev. Lett., 73, 1632, 1994)(Roberts, C.J., and P.G. Debenedetti, J. Chem. Phys., 105, 658, 1996)(Roberts, C.J., P.G. Debenedetti, and A.Z. Panagiotopoulos, Phys. Rev.

    Graphical abstract: Co x Fe 3−x O 4 was proved to possess higher peroxidase-like activity comparing with Fe 3 O 4 MNPs. It could effectively catalyze the reaction between 3,3,5,5-tetramethylbenzidine (TMB) and H 2 O 2 under 40 °C within 15 min. So this proposed method was used for measuring dopamine. The color variation was very obvious on visual observation, which offered a convenient approach to detect DA by naked eye. -- Highlights: • The Co x Fe 3−x O 4 MNPs were firstly prepared by a simple coprecipitation method. • Co x Fe 3−x O 4 MNPs could effectively catalyze the reaction between TMB and H 2 O 2 . • This colorimetric analytical method was convenient, economic and speedy. • The method had been applied to detection of DA in Shan Yao and human serum sample. -- Abstract: In this study, cobalt doped magnetic composite nanoparticles (Co x Fe 3−x O 4 MNPs) were firstly prepared through a simple and convenient coprecipitation approach. The characterization results from EDX, ICP-AES, TEM, XRD and XPS showed that the cobalt atoms might be located in the lattice position instead of the part of iron atoms. Co x Fe 3−x O 4 MNPs possessed higher peroxidase-like activity comparing with Fe 3 O 4 MNPs, although they were similar in crystal structure, size distribution and morphology. The as-prepared nanomaterials could effectively catalyze the reaction between 3,3,5,5-tetramethylbenzidine (TMB) and H 2 O 2 under 40 °C within 15 min. Dopamine (DA) has some reducibility due to the existence of phenol hydroxyl group, which results in it can consume H 2 O 2 and cause the blue shallowing of the reaction solution between H 2 O 2 and TMB. A visual, sensitive and simple colorimetric method based on Co x Fe 3−x O 4 MNPs as peroxidase mimetics was developed for detecting DA. Good linear relationship and recoveries for DA were obtained from 0.6 to 8.0 μM and 98.7 to 101.0%, respectively. The limit of detection (LOD) of the proposed method was calculated as 0

    Simultaneous monitoring of several neurotransmitters (NTs) linked to Parkinson's disease (PD) has important scientific significance for PD related pathology, pharmacology and drug screening. A new simple, fast and sensitive analytical method, based on in situ derivatization-ultrasound-assisted dispersive liquid-liquid microextraction (in situ DUADLLME) in a single step, has been proposed for the quantitative determination of catecholamines and their biosynthesis precursors and metabolites in rat brain microdialysates. The method involved the rapid injection of the mixture of low toxic bromobenzene (extractant) and acetonitrile (dispersant), which containing commercial Lissamine rhodamine B sulfonyl chloride (LRSC) as derivatization reagent, into the aqueous phase of sample and buffer, and the following in situ DUADLLME procedure. After centrifugation, 50μL of the sedimented phase (bromobenzene) was directly injected for ultra high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) detection in multiple reaction monitoring (MRM) mode. This interesting combination brought the advantages of speediness, simpleness, low matrix effects and high sensitivity in an effective way. Parameters of in situ DUADLLME and UHPLC-MS/MS conditions were all optimized in detail. The optimum conditions of in situ DUADLLME were found to be 30μL of microdialysates, 150μL of acetonitrile containing LRSC, 50μL of bromobenzene and 800μL of NaHCO3-Na2CO3 buffer (pH 10.5) for 3.0min at 37°C. Under the optimized conditions, good linearity was observed with LODs (S/N>3) and LOQs (S/N>10) of LRSC derivatized-NTs in the range of 0.002-0.004 and 0.007-0.015 nmol/L, respectively. It also brought good precision (3.2-12.8%, peak area CVs%), accuracy (94.2-108.6%), recovery (94.5-105.5%) and stability (3.8-8.1%, peak area CVs%) results. Moreover, LRSC derivatization significantly improved chromatographic resolution and MS detection sensitivity of NTs when compared with the

    A Different Approach to the Skills and Resource Shortage The Nuclear Industry has for many years been concerned about a skills and resource shortage. This has been due to a poor perception of the industry by those on the outside, highly competitive industries vying for the same resource pool, a steep retirement curve for highly qualified staff and a lack of graduates entering industry. Here in the UK the creation of the National Skill Academy for Nuclear (NSAN) has put in place a framework to record skills and look to accredit the training providers in the nuclear industry to ensure that the correct skills for the future are available. This has gone some way to solving the skills problem and developing a well recognised accredited system but what about resource - where are the additional qualified resources going to be found? Part of the Solution - A Resource Exchange. How do we solve the skills shortage? We come together as an industry and share the available resource through a collaborative resource exchange. It has been done before in the IT industry when rates for specialists hit Pounds 1500 per day and recruitment agencies were charging extortionate fees for providing temporary resource. ReTek Consulting have developed the ReTek Resource Exchange to provide a neutral collaborative platform across the supply chain; from large scale infrastructure companies and joint venture platforms through to small companies and independent consultants. Using the ReTek Exchange permanent staff are made available to work for others during periods of under-utilisation. Links with similar highly regulated industries enable further management of peaks and troughs and a growth in experienced nuclear professionals through focused training and development. The Benefits of the ReTek Exchange are: - Increased utilisation of your current workforce. - Shared cost of permanent staff. - Speedy access to staff available in your region. - Reduced need for contract or agency staff. - Access

    Full Text Available Abstract Background Activity levels are known to decline with age and there is growing evidence of associations between the school environment and physical activity. In this study we investigated how objectively measured one-year changes in physical activity may be associated with school-related factors in 9- to 10-year-old British children. Methods Data were analysed from 839 children attending 89 schools in the SPEEDY (Sport, Physical Activity, and Eating behaviours: Environmental Determinants in Young People study. Outcomes variables were one year changes in objectively measured sedentary, moderate, and vigorous physical activity, with baseline measures taken when the children were 9–10 years old. School characteristics hypothesised to be associated with change in physical activity were identified from questionnaires, grounds audits, and computer mapping. Associations were examined using simple and multivariable multilevel regression models for both school (9 am – 3 pm and travel (8–9 am and 3–4 pm time. Results Significant associations during school time included the length of the morning break which was found to be supportive of moderate (β coefficient: 0.68 [p: 0.003] and vigorous (β coefficient: 0.52 [p: 0.002] activities and helps to prevent adverse changes in sedentary time (β coefficient: -2.52 [p: 0.001]. During travel time, positive associations were found between the presence of safe places to cross roads around the school and changes in moderate (β coefficient: 0.83 [p:0.022] and vigorous (β coefficient: 0.56 [p:0.001] activity, as well as sedentary time (β coefficient: -1.61 [p:0.005]. Conclusion This study suggests that having longer morning school breaks and providing road safety features such as cycling infrastructure, a crossing guard, and safe places for children to cross the road may have a role to play in supporting the maintenance of moderate and vigorous activity behaviours, and preventing the development of

    Road traffic injuries (RTIs) are a major public health problem, requiring concerted efforts both for their prevention and a reduction of their consequences. Timely arrival of the Emergency Medical Service (EMS) at the crash scene followed by speedy victim transportation by trained personnel may reduce the RTIs' consequences. The first 60 minutes after injury occurrence--referred to as the "golden hour"--are vital for the saving of lives. The present study was designed to estimate the average of various time intervals occurring during the pre-hospital care process and to examine the differences between these time intervals as regards RTIs on urban and interurban roads. A retrospective cross-sectional study was designed and various time intervals in relation to pre-hospital care of RTIs identified in the ambulance dispatch centre in Urmia, Iran from 20 March 2005 to 20 March 2007. All cases which resulted in ambulance dispatches were reviewed and those that had complete data on time intervals were analyzed. In total, the cases of 2027 RTI victims were analysed. Of these, 61.5% of the subjects were injured in city areas. The mean response time for city locations was 5.0 minutes, compared with 10.6 minutes for interurban road locations. The mean on-scene time on the interurban roads was longer than on city roads (9.2 vs. 6.1 minutes, p transport times from the scene to the hospital were also significantly longer for interurban incidents (17.1 vs. 6.3 minutes, p transport and total time intervals among EMS responding to RTI incidents were longer for interurban roads, compared to the city areas. More research should take place on needs-to and access-for EMS on city and interurban roads. The notification interval seems to be a hidden part of the post-crash events and indirectly affects the "golden hour" for victim management and it needs to be measured through the establishment of the surveillance systems.

    Existing training methods for neuroendoscopic surgery have mainly emphasized the acquisition of anatomical knowledge and procedures for operating an endoscope and instruments. For laparoscopic surgery, various training systems have been developed to teach handling of an endoscope as well as the manipulation of instruments for speedy and precise endoscopic performance using both hands. In endoscopic endonasal surgery (EES), especially using a binostril approach to the skull base and intradural lesions, the learning of more meticulous manipulation of instruments is mandatory, and it may be necessary to develop another type of training method for acquiring psychomotor skills for EES. Authors of the present study developed an inexpensive, portable personal trainer using a webcam and objectively evaluated its utility. Twenty-five neurosurgeons volunteered for this study and were divided into 2 groups, a novice group (19 neurosurgeons) and an experienced group (6 neurosurgeons). Before and after the exercises of set tasks with a webcam box trainer, the basic endoscopic skills of each participant were objectively assessed using the virtual reality simulator (LapSim) while executing 2 virtual tasks: grasping and instrument navigation. Scores for the following 11 performance variables were recorded: instrument time, instrument misses, instrument path length, and instrument angular path (all of which were measured in both hands), as well as tissue damage, max damage, and finally overall score. Instrument time was indicated as movement speed; instrument path length and instrument angular path as movement efficiency; and instrument misses, tissue damage, and max damage as movement precision. In the novice group, movement speed and efficiency were significantly improved after the training. In the experienced group, significant improvement was not shown in the majority of virtual tasks. Before the training, significantly greater movement speed and efficiency were demonstrated in

    Single-tooth implant restorations are commonly used to replace anterior maxillary teeth. The esthetic, functional, and biologic outcomes are, in part, a function of the abutment and crown. The purpose of this clinical study was to describe the implant, abutment, and crown survival and complication rates for CAD/CAM zirconia abutment and lithium disilicate crown restorations for single-tooth implants. As part of a broader prospective investigation that enrolled and treated 141 participants comparing tissue responses at the conical interface (CI; AstraTech OsseoSpeed), flat-to-flat interface (FI; NobelSpeedy), and platform-switch interface (PS; NanoTite Certain Prevail) of single-tooth implants, computer-aided design and computer-aided manufacturing (CAD/CAM) zirconia abutments (ATLANTIS Abutment) and cemented lithium disilicate (e.max) crowns were used in the restoration of all implants. After 2.4 years in function (3 years after implant placement), the implant, abutment, and crown of 110 participants were evaluated. Technical and biologic complications were recorded. Demographic results were tabulated as percentages with mean values and standard deviations. Abutment survival was calculated with the Kaplan-Meier method. After 2.4 years, no abutments or crowns had been lost. Abutment complications (screw loosening, screw fracture, fracture) were absent for all 3 implant groups. Crown complications were limited to 2 crowns debonding and 1 with excess cement (2.5%). Five biological complications (4.0%) were recorded. The overall complication rate was 6.5%. CAD/CAM zirconia abutments restored with cemented lithium disilicate crowns demonstrated high survival on 3 different implant-abutment interface designs. No abutment or abutment screw fracture occurred. The technical complications observed after 2.4 years were minor and reversible. The use of CAD/CAM zirconia abutments with cemented lithium disilicate crowns is associated with high technical and biologic success at 2

    Background Promoting physical activity in youth is important for health, but existing physical activity interventions have had limited success. We aimed to inform intervention design by i) describing drop-out, continuation and uptake of specific activities over the transition to adolescence; and ii) examining Variety (number of different activities/week) and Frequency (number of activity session/week) of activity participation and their associations with changes in objectively measured physical activity from childhood to adolescence. Methods At age 10.2±0.3 and 14.2±0.3 years, 319 children in the SPEEDY study (46% boys) wore GT1M Actigraph accelerometers for 7 days and provided self-reported participation (never, once, 2 to 3 times or four or more times, over the last 7 days) in 23 leisure-time activities. Associations of change in moderate-to-vigorous intensity PA (MVPA) (≥2000 counts/minute) and change in total physical activity (TPA) (average accelerometer counts/minute) with exposure variables Z-score transformed (change in) Variety and Frequency were examined using multilevel linear regression, clustered by school, in simple and adjusted models. Results The number of children ever reporting a specific activity ranged from 30 (‘Hockey’) to 279 (‘Running or jogging’). Some activities were susceptible to drop-out (e.g. ‘Skipping’) but others were commonly continued or taken up (e.g. ‘Household chores’). Overall, Variety and Frequency declined (mean±SD ΔVariety −3.1±4.4 activities/week; ΔFrequency −7.2±12.0 session/week). ΔMVPA and ΔTPA were not associated with Variety or Frequency at baseline, nor with ΔVariety or ΔFrequency (p>0.29 in all models). Conclusions Popularity of specific activities as well as drop-out, continuation and uptake should be considered in future intervention development. Activities that are commonly continued or taken up may be more valuable to encourage in interventions than those with low participation or

    The regulation of the carbon cycle is a critical ecosystem service provided by forests globally. It is, therefore, necessary to have robust techniques for speedy assessment of forest biophysical parameters at the landscape level. It is arduous and time taking to monitor the status of vast forest landscapes using traditional field methods. Remote sensing and GIS techniques are efficient tools that can monitor the health of forests regularly. Biomass estimation is a key parameter in the assessment of forest health. Polarimetric SAR (PolSAR) remote sensing has already shown its potential for forest biophysical parameter retrieval. The current research work focuses on the retrieval of forest biophysical parameters of tropical deciduous forest, using fully polarimetric spaceborne C-band data with Polarimetric SAR Interferometry (PolInSAR) techniques. PolSAR based Interferometric Water Cloud Model (IWCM) has been used to estimate aboveground biomass (AGB). Input parameters to the IWCM have been extracted from the decomposition modeling of SAR data as well as PolInSAR coherence estimation. The technique of forest tree height retrieval utilized PolInSAR coherence based modeling approach. Two techniques - Coherence Amplitude Inversion (CAI) and Three Stage Inversion (TSI) - for forest height estimation are discussed, compared and validated. These techniques allow estimation of forest stand height and true ground topography. The accuracy of the forest height estimated is assessed using ground-based measurements. PolInSAR based forest height models showed enervation in the identification of forest vegetation and as a result height values were obtained in river channels and plain areas. Overestimation in forest height was also noticed at several patches of the forest. To overcome this problem, coherence and backscatter based threshold technique is introduced for forest area identification and accurate height estimation in non-forested regions.

    Full Text Available OBJECTIVES AND BACKGROUND The management of sepsis requires a hasty identification of infection, through the application of different dynamic strategies in prehospital and hospital conditions, through the implementation of a number of changes and by measuring the outcome of these changes thus ensuring a decrease in the mortality rate and allowing a rapid identification of the infection MATERIALS AND METHODS Procalcitonin (PCT was used as a marker of sepsis in emergency departments. Due to its sensitivity and molecular peculiarities, procalcitonin allows a rapid diagnosis of severe bacterial infections, and is able to differentiate viral infections from bacterial ones. It is also able to differentiate an infectious process from an inflammation, thus sketching a clinically applicable protocol that can be implemented and continuously improved. RESULTS The identification of the infectious process in the emergency department within 24 hours leads to a decreased in the mortality rate. Speedy diagnostic methods of infection based on the determination of specific, rapidly measurable, markers – procalcitonin in our case - can confirm the presence of sepsis and its’ outcome. CONCLUSIONS Prehospital determination of procalcitonin (PCT is recommended in the early diagnosis of sepsis and is also an indicator of its severity, starting from a solid theoretical database that is justified by the efficiency and effectiveness of its usage.

According to the law, citizens can put forward their information requests either orally (at the premises or over the phone or in writing (by mail, fax, email, etc. and public offices are obligated to respond within five working days. For this dialogical communication to be efficient, both parties must follow well-developed and tacitly accepted communication practices. According to Swales’ (1990 genre theory, the analysis of the inner structure of information requests demonstrates that a prototypical information request consists of six different steps: creating of a communicative situation, justification of the request, putting forward the main request, and if needed, also an additional request, offering additional information and of an ending of the communicative situation. Some differences can be found in the structure of the requests based on whether they were sent in via a web interface or by email. While a part of an information request sent in by email is also to end the particular communicative situation (email usually ends with polite wishes and sender’s name then in information requests sent by web interfaces senders often limit themselves to only voicing their main request. The requests in the information requests analysed in this study are formulated mainly as pleas. The please-construction in the request helps to build a short and speedy information exchange and it also contributes towards decreasing the nature or tone of the request. For example, it allows one to use the imperative mood or to change a direct question into an indirect one. In addition to the pleading acts, Estonian information requests also contain wishing and asking acts whereas other ways of expressing the request (verbless constructions

    Full Text Available Objective – To investigate reasons why undergraduate and postgraduate students choose to use chat reference services and their satisfaction with the experience. Design – User survey. Setting – Large academic library in the United States. Subjects – A total of 341 library users took part in the survey. Of these, 79 were graduate students, 215 undergraduates, 21 staff, 5 alumni and 21 members of the public. Method – A user survey form was posted on the library website for a period of one month (March 2003. Users of the chat reference service received an automatic closing message asking them to complete the survey. Responses were fed into a database to be analysed by the research staff. Additional data was also gathered about the behaviour of all users of the chat service during that period – both responders and non‐responders. Main results – The most popular reason for choosing to use a chat service was the desire for a speedy response, followed by ‘distance from the library’. Responders chose to use chat to ask a range of different kinds of questions. Nearly half (45% were looking for a specific resource and 23% were seeking help at the beginning of their research. There were notable differences between undergraduate and graduate students. Twice as many undergraduates as graduates used the service to help them get started on their research. Graduates were three times as likely as undergraduates to be using the service to address technical problems they were having with the website. Overall satisfaction with the service was extremely high, with 77.5% rating it 5 out of 5 and 94.5% giving it 4 or 5 out of 5. Conclusion – Chat reference services are popular with users primarily because they are quick and convenient. However, users expect that these services will be able to deal with all types of questions, including help with research. This challenges an assumption by library staff that the medium is only suitable for short

    As an alternative to the tort or fault-based system, a no-fault compensation system has been viewed as having the potential to overcome problems inherent in the tort system by providing fair, speedy and adequate compensation for medically injured victims. Proponents of the suggested no-fault compensation system have argued that this system is more efficient in terms of time and money, as well as in making the circumstances in which compensation is paid, much clearer. However, the arguments against no-fault compensation systems are mainly on issues of funding difficulties, accountability and deterrence, particularly, once fault is taken out of the equation. Nonetheless, the no-fault compensation system has been successfully implemented in various countries but, at the same time, rejected in some others, as not being implementable. In the present trend, the no-fault system seems to fit the needs of society by offering greater access to justice for medically injured victims and providing a clearer "road map" towards obtaining suitable redress. This paper aims at providing the readers with an overview of the characteristics of the no fault compensation system and some examples of countries that have implemented it. Qualitative Research-Content Analysis. Given the many problems and hurdles posed by the tort or fault-based system, it is questionable that it can efficiently play its role as a mechanism that affords fair and adequate compensation for victims of medical injuries. However, while a comprehensive no-fault compensation system offers a tempting alternative to the tort or fault-based system, to import such a change into our local scenario requires a great deal of consideration. There are major differences, mainly in terms of social standing, size of population, political ideology and financial commitment, between Malaysia and countries that have successfully implemented no-fault systems. Nevertheless, implementing a no-fault compensation system in Malaysia is not

    In the age of high speed Internet where people can interact instantly, scientific tools have lacked technology which can incorporate this concept of communication using the web. To solve this issue a web application for geological studies has been created, tentatively titled WebViz. This web application utilizes tools provided by Google Web Toolkit to create an AJAX web application capable of features found in non web based software. Using these tools, a web application can be created to act as piece of software from anywhere in the globe with a reasonably speedy Internet connection. An application of this technology can be seen with data regarding the recent tsunami from the major japan earthquakes. After constructing the appropriate data to fit a computer render software called HVR, WebViz can request images of the tsunami data and display it to anyone who has access to the application. This convenience alone makes WebViz a viable solution, but the option to interact with this data with others around the world causes WebViz to be taken as a serious computational tool. WebViz also can be used on any javascript enabled browser such as those found on modern tablets and smart phones over a fast wireless connection. Due to the fact that WebViz's current state is built using Google Web Toolkit the portability of the application is in it's most efficient form. Though many developers have been involved with the project, each person has contributed to increase the usability and speed of the application. In the project's most recent form a dramatic speed increase has been designed as well as a more efficient user interface. The speed increase has been informally noticed in recent uses of the application in China and Australia with the hosting server being located at the University of Minnesota. The user interface has been improved to not only look better but the functionality has been improved. Major functions of the application are rotating the 3D object using buttons

    To dosimetrically validate AcurosXB algorithm for Volumetric Modulated Arc Therapy (VMAT) in comparison with standard clinical Anisotropic Analytic Algorithm(AAA) and Collapsed Cone Convolution(CCC) dose calculation algorithms. AcurosXB dose calculation algorithm is available with Varian Eclipse treatment planning system (V10). It uses grid-based Boltzmann equation solver to predict dose precisely in lesser time. This study was made to realize algorithms ability to predict dose accurately as its delivery for which five clinical cases each of Brain, Head&Neck, Thoracic, Pelvic and SBRT were taken. Verification plans were created on multicube phantom with iMatrixx-2D detector array and then dose prediction was done with AcurosXB, AAA & CCC (COMPASS System) algorithm and the same were delivered onto CLINAC-iX treatment machine. Delivered dose was captured in iMatrixx plane for all 25 plans. Measured dose was taken as reference to quantify the agreement between AcurosXB calculation algorithm against previously validated AAA and CCC algorithm. Gamma evaluation was performed with clinical criteria distance-to-agreement 3&2mm and dose difference 3&2% in omnipro-I'MRT software.

    Over the last 25 years, a tremendous progress has been made in the Earth science space-based remote sensing observations, technologies and algorithms. Such advancements have improved the predictability by providing lead-time and accuracy of forecast in weather, climate, natural hazards, and natural resources. It has further reduced or bounded the overall uncertainties by partially improving our understanding of planet Earth as an integrated system that is governed by non-linear and chaotic behavior. Many countries such US, European Community, Japan, China and others have invested billions of dollars in developing and launching space-based assets in the low earth (LEO) and geostationary (GEO) orbits. However, the wealth of this scientific knowledge that has potential of extracting monumental socio-economic benefits from such large investments have been slow in reaching to public and decision makers. For instance, there are a number of areas such as energy forecasting, aviation safety, agricultural competitiveness, disaster management, security, air quality and public health can directly take advantage. Nevertheless, we all live in a global economy that depends on access to the best available Earth Science information for all inhabitants of this planet. This paper surveys and examines a number such applications in terms of their architecture, maturity and economic applicability as they apply to the societal needs. A detailed analysis is also presented of various challenges and issues that pertain to a number of areas such as: (1) difficulties in making a speedy transition of data and information from observations and models to relevant Decision Support Systems (DSS) or tools, (2) data and models inter-operability issues, (3) limitations of spatial, spectral and temporal resolution, (4) communication limitations as dictated by the availability of image processing and data compression techniques. Additionally, the most critical element amongst all is the organizational

    rhythmically. Moreover, the training of conversational speech formulas led to long-term progress in the production of formulaic language. The patients were able to establish their own individual formulaic repertoire in order to communicate some basic needs in daily life. This finding may result from the fact that, according to present knowledge, the production of formulaic language engages bilateral neural networks including right frontotemporal areas, the right basal ganglia and, possibly, the right cerebellum (Hughlings-Jackson, 1878; Speedie et al., 1993; Ackermann et al., 1998; Van Lancker Sidtis & Postman, 2006; Sidtis et al., 2009. In other words, left-hemisphere stroke patients may use right-hemisphere language resources to produce conversational speech formulas, whether they are sung or rhythmically spoken. In conclusion, the current experiments highlight the critical role of rhythm and conversational speech formulas in melody-based aphasia therapy.

    The discovery by the Interstellar Boundary Explorer (IBEX) of a "Ribbon" in the measurements of Energetic Neutral Particles (ENA) was a major surprise that lead to the re-thinking of the Physics underpinning the heliosphere-intergalactic medium boundary dynamics. Several physical models have been proposed and tested in their ability to mimic the IBEX observations. Some of the ENA IBEX's include the following features: 1) The presence of fine structure within the ribbon suggests that the physical properties of it exhibit small-scale spacial structure and possibly rapid small-scale variations. 2) The ribbon is a fairly narrow feature at low energies and broadens with increasing energy;The IBEX detectors were designed to maximize count rate by incorporating wide angular and broad energy acceptance. Thus far, the existing mapping software used by the IBEX Science Operation Center has not been design with the "Ribbon" ( 20o wide) in mind: the current generation of maps are binned in 6o longitude pixels by 6o latitude pixels (so the pixels are all of the same size in angle and are quite "blocky"). Furthermore, the instrumental point spread function has not been deconvolved, making any potential narrow features broader than they are. An improvement in the spatial resolution of the IBEX maps would foster a better understanding of the Ribbon and its substructure, and thus reply to some of the basic and profound questions related to its origin, the nature of the outer boundaries of the our solar system and the surrounding interstellar Galactic medium.Here we report on the application of the Bayesian image reconstruction algorithm "Speedy Pixons" to the ENA data with the aim to sharpen the ENA IBEX maps. A preliminary application allow us to conclude that: The peaks in the count rate do appear to be more enhanced in the reconstruction; The reconstruction is clearly denoised; The "Ribbon" is better defined in the reconstruction. We are currently studying the implications of

    in the mean value of the function. Using statistical significance tests both at the local and field level, it is shown that the climatology of the SPEEDY model is not modified by the changed time stepping scheme; hence, no retuning of the parameterizations is required. It is found the accuracy of the medium-term forecasts is increased by using the RAW filter.
