    Enterprise VRD, a stent frequently used to assist coil embolization of cerebral aneurysms, has been upgraded to reduce the risk of incomplete stent apposition (ISA), a known risk factor for thromboembolic complications. To compare the performances of Enterprise VRD and Enterprise VRD2 in curved vessels, and to investigate a deployment method that takes advantage of the features of Enterprise VRD2 to achieve better vessel wall apposition. A silicone vascular model connected to a temperature-adjustable perfusion circuit was used. First, Enterprise VRD and Enterprise VRD2 were deployed under fluoroscopy and then ISA was evaluated as the stent cross-sectional area ratio at the curved segment of the vessel. For the measurements, each stent was deployed in vessels with different angles of curvature. Second, the incidence of ISA after insertion of Enterprise VRD2 by the 'pushing over outer curve technique', in which stents are deployed along the outer curve of vessels with continuous wire advancement, was compared with 'Heller's push and pull technique'. For all stents, the cross-sectional area ratio decreased with acute curvature of the vessel. Comparisons of the two stents showed that Enterprise VRD2 was better than Enterprise VRD in maintaining a greater cross-sectional area ratio in curved vessels. In addition, kinking with an acute curvature was also minimized with Enterprise VRD2. Furthermore, ISA was reduced using our technique with Enterprise VRD2. Enterprise VRD2 is superior to Enterprise VRD in reducing ISA in curved vessels and can alter ISA according to the deployment technique used. Published by the BMJ Publishing Group Limited.

    Protein glycosylation is one of the most important posttranslational modifications. Numerous biological functions are related to protein glycosylation. However, analytical challenges remain in the glycoprotein analysis. To overcome the challenges associated with glycoprotein analysis, many analytical techniques were developed in recent years. Enrichment methods were used to improve the sensitivity of detection, while HPLC and mass spectrometry methods were developed to facilitate the separation of glycopeptides/proteins and enhance detection, respectively. Fragmentation techniques applied in modern mass spectrometers allow the structural interpretation of glycopeptides/proteins, while automated software tools started replacing manual processing to improve the reliability and throughput of the analysis. In this chapter, the current methodologies of glycoprotein analysis were discussed. Multiple analytical techniques are compared, and advantages and disadvantages of each technique are highlighted. © 2017 Elsevier Inc. All rights reserved.

    Nowadays, power quality (PQ) plays a very important role in power systems. So that is why it is very important to use suitable tools allowing a precise detection of anomalies and perturbations in power systems. Given traditional analysis techniques, such as Fourier Transform, today new tools are being developed based on domain transformation, such as Wavelet Transform (WT) or S-Transform (ST), along with Artificial Intelligence (AI) techniques such as Fuzzy Logic (FL) or Artificial Neural Networks (ANN). In this paper, new algorithm and mathematic techniques are reviewed and discussed, and also compared with traditional techniques, revealing the precision and superiority achieved with these new techniques. ST and WT is detailed, basically, as a tool with great scope and future in power quality analysis because of its precision, noise immunity and its contribution with quality information about PQ.

    Mangrove forests grow in the estuaries of 124 tropical countries around the world. Because in-situ monitoring of mangroves is difficult and time-consuming, remote sensing technologies are commonly used to monitor these ecosystems. Landsat satellites have provided regular and systematic images of mangrove ecosystems for over 30 years, yet researchers often cite budget and infrastructure constraints to justify the underuse this resource. Since 2001, over 50 studies have used Landsat or ASTER imagery for mangrove monitoring, and most focus on the spatial extent of mangroves, rarely using more than five images. Even after the Landsat archive was made free for public use, few studies used more than five images, despite the clear advantages of using more images (e.g. lower signal-to-noise ratios). The main argument of this paper is that, with freely available imagery and high performance computing facilities around the world, it is up to researchers to acquire the necessary programming skills to use these resources. Programming skills allow researchers to automate repetitive and time-consuming tasks, such as image acquisition and processing, consequently reducing up to 60% of the time dedicated to these activities. These skills also help scientists to review and re-use algorithms, hence making mangrove research more agile. This paper contributes to the debate on why scientists need to learn to program, not only to challenge prevailing approaches to mangrove research, but also to expand the temporal and spatial extents that are commonly used for mangrove research.

    Full Text Available ABSTRACT Introduction: Treatments with dental surgery seek to displace tooth to the correct position within the dental arch. Objective: To report a clinical case that took advantage of an unerupted third molar. Case history: A male patient, 18 years of age, was referred by his dentist to evaluate the third molars. The clinical exam revealed no visible lower third molars. The computed tomography (CT exam showed the presence of a supernumerary tooth in the region of the mandibular ramus, on the left side, and impaction of the third molar, which was causing root resorption on the second molar, thus making it impossible to remain in the buccal cavity. The preferred option, therefore, was to remove both second molar and the supernumerary tooth, in addition to attaching a device to the third molar during surgery for further traction. Results: After 12 months, the third molar reached the proper position. Conclusion: When a mandibular second permanent molar shows an atypical root resorption, an impacted third molar can effectively substitute the tooth by using an appropriate orthodontic-surgical approach.

    Anterior lumbar interbody fusion (ALIF) for lumbar interbody fusion from L2 to the sacrum has been an established technique for decades. The advantages and disadvantages of ALIF compared to posterior interbody fusion techniques are discussed. The operative technique is described in detail. Complications and avoidance strategies are discussed. This article is based on a selective literature search using PubMed and the experience of the authors in this medical field. The advantages of ALIF compared to posterior fusion techniques are the free approach to the anterior disc space without opening of the spinal canal or the neural foramina. This gives the possibility of an extensive anterior release and placement of the largest possible cages without the risk of neural structure damage. The disadvantages of ALIF are the additional anterior approach and the related complications. The most frequent complication is due to damage of vessels. The rate of complications is significantly increased in revision surgery. The ALIF technique meaningfully expands the repertoire of the spinal surgeon especially for the treatment of non-union after interbody fusion, in patients with epidural scar tissue at the index level and spinal infections. Advantages and disadvantages should be considered when evaluating the indications for ALIF.

    Precision measurements of ultrasmall linear velocities of one of the mirrors in a Michelson interferometer are performed using two different weak-value techniques. We show that the technique of almost-balanced weak values (ABWV) offers practical advantages over the technique of weak-value amplification, resulting in larger signal-to-noise ratios and the possibility of longer integration times due to robustness to slow drifts. As an example of the performance of the ABWV protocol we report a velocity sensitivity of 60 fm/s after 40 h of integration time. The sensitivity of the Doppler shift due to the moving mirror is 150 nHz.

    Full Text Available Face-to-face interviews have long been the dominant interview technique in the field of qualitative research. In the last two decades, telephone interviewing became more and more common. Due to the explosive growth of new communication forms, such as computer mediated communication (for example e-mail and chat boxes, other interview techniques can be introduced and used within the field of qualitative research. For a study in the domain of virtual teams, I used various communication possibilities to interview informants as well as face-to-face interviews. In this article a comparison will be made concerning the advantages and disadvantages of face-to-face, telephone, e-mail and MSN messenger interviews. By including telephone and MSN messenger interviews in the comparison, the scope of this article is broader than the article of BAMPTON and COWTON (2002. URN: urn:nbn:de:0114-fqs0604118

    Full Text Available Objective:Tibial shaft fractures are straightforward to treat but when associated with soft tissue injury particularly at the nail entry/plate insertion site or there is significant comminution proximally or a large butterfly fragment/a second split component in the posterior coronal plane, it is a challenge to the treating surgeon. The aim of the present report is to describe the technique of posterior coronal plating in such a scenario and its advantages. Methods:Between July 2008 and June 2011, 12 patients were pro spectively treated by this approach using 4.5 mm broad dynamic compression plates. Results:The time of bony consolidation and full weight bearing averaged 21.7 weeks (range, 16-26 weeks. Patients were followed up for at least 24 months (range, 24-48 months. At 1 year postoper atively, no loss in reduction or alignment was observed. Mean Hospital for Lower Extremity Measurement Functional Score was 72.8 (range, 64-78. All patients were satisfied with their treatment outcomes. Conclusion:Direct posterior approach and fixation using prone position helps to visualise the fracture fragments and provide rigid fixation. The approach is simple and extensile easily, apart from advantages of less soft tissue and hardware problems compared to standard medial or lateral plating.

    2017-01-01

    Full Text Available This paper studies internal reference price effects when competitive firms face reference price effects and make decisions based on partial information, where their decision-making mechanism is modeled by a dynamic adjustment process. It is shown that the evolution of this dynamic adjustment goes to stabilization if both adjustment speeds are small and the complexity of this evolution increases in adjustment speeds. It is proved that the necessary condition for flip bifurcation or Neimark-Sacker bifurcation will occur with the increase of adjustment speed in two special cases. What is more, numerical simulations show that these bifurcations do occur. Then, the impacts of parameters on stability and profits are investigated and some management insights for firms with limited information to take advantage of reference price effects are provided.

    Most designed functions in biomedical nanotechnology are directly influenced by interactions of biological molecules with nano surfaces. Here, we explored and detected the most favorable adsorption conformation of cytochrome c on graphene by measuring the adsorption energy, the number of contact atoms, and the minimal distance between protein and surface. From the root mean square deviation of the protein backbone, the radius of gyration, and the proportion of secondary structure, it is revealed that cytochrome c does not deform significantly and the secondary structures are preserved to a large extent. The residues, Lys, Phe and Thr contribute significantly to the adsorption of cytochrome c to graphene. The long hydrophobic and flexible alkyl tail of Lys, the π-π stacking interaction between Phe and graphene, and the presence of abundant Thr constitute the driving force for the stable adsorption of cytochrome c on graphene. Cytochrome c is adsorbed to graphene with the group heme lying almost perpendicular to the graphene, and the distance between Fe atom and the graphene is 10.15 A, which is shorter than that between electron donor and receptor in many other biosystems. All the results suggest that the most favorable adsorption takes the most advantageous conformation for electron transfer, which promotes significantly the electron transfer between graphene and cytochrome c. The findings might provide new and important information for designs of biomedical devices or products with graphene-based nanomaterials.

  15. Innovating in the teaching of Chemical Equilibrium: Taking effective advantage of Information and Communication Technologies

    Fonseca, Susana Cristina Morais da

    Chemical Equilibrium (CE) is a good example of the specific nature of chemistry. The understanding of this theme requires the conceptualization of macroscopic events, as well as explanations of sub microscopic nature, application of symbolic language and mathematics. CE is commonly identified as a topic suitable for the pedagogical use of Information and Communication Technologies (ICT). However, the growth in the roll of digital resources for the teaching of CE, that took place in the last decades, was not accompanied by a decrease in the signalling of students' difficulties and misconceptions in the subject. This fact, points out the relevance of clarifying the circumstances under which digital resources turn out to be useful in the teaching of CE and develop educative modules that take into account the findings and recommendations from the literature. This project aims to bring a contribution to take advantage form ICT potential in the teaching of CE. The objectives underlying the main purpose of the project were defined according to literature review, which crosses three fundamental dimensions (scientific, pedagogical and technological). The project also benefited from the previous experience of the group and the collaboration with an European project (CROSSNET). The level of abstraction necessary for the understanding of the scientific model is pointed out as the major source of difficulties in the learning of CE, while also referred as a privileged target for the intervention of ICT. In this context, we introduce the expression "facilitating abstraction" to summarize the idea of supporting students' abstract thinking process during the learning of formal concepts. This idea has gained importance throughout the project leading to the development of a pedagogical approach to facilitate abstraction in the learning of CE. Although based on the use of ICT, the main purpose wasn't to introduce new digital resources in the saturated field of CE. Instead, the

    During the software development life cycle process, basic testing starts with the development team. At the end of the development process, an acceptance test is performed for the user to ensure that the deliverable is acceptable. Ideally, the delivery is an operational product with zero defects. However, the goal of zero defects is normally not achieved but is successful to various degrees. With the emphasis on building low cost ground support systems while maintaining a quality product, a key element in the test process is simulator capability. This paper reviews the Transportable Payload Operations Control Center (TPOCC) Advanced Spacecraft Simulator (TASS) test tool that is used in the acceptance test process for unmanned satellite operations control centers. The TASS is designed to support the development, test and operational environments of the Goddard Space Flight Center (GSFC) operations control centers. The TASS uses the same basic architecture as the operations control center. This architecture is characterized by its use of distributed processing, industry standards, commercial off-the-shelf (COTS) hardware and software components, and reusable software. The TASS uses much of the same TPOCC architecture and reusable software that the operations control center developer uses. The TASS also makes use of reusable simulator software in the mission specific versions of the TASS. Very little new software needs to be developed, mainly mission specific telemetry communication and command processing software. By taking advantage of the ground data system attributes, successful software reuse for operational systems provides the opportunity to extend the reuse concept into the test area. Consistency in test approach is a major step in achieving quality results.

    . Our goal is to expand the use of these modules to a more broad public audience, including at a future campus/public event know as "All Things Water". We have also organized a walking tour/demo with 3rd-5th graders in a small mining town west of Boulder where we hiked to an old historical mine site, measured water quality (pH, dissolved lead, conductivity), and coated the inside of small bottles with silver. Organizing and hosting a conference can also be a great way to facilitate a discussion of ideas within the community. "All Things STEM" organized a broad student research conference related to water quality and water treatment which included research from 22 students from 11 different countries. We worked with 12 local engineering consultants, municipalities, and local businesses to provide 2000 for student awards. Our presentation will focus on lessons we have learned on how to take advantage of student energy, excitement, and time on campus to receive funding opportunities for planning events that engage the public. We will also talk about our experiences in using student energy to develop partnerships with K-12 schools, community groups, and industry professionals.

  19. From field to factory-Taking advantage of shop manufacturing for the pebble bed modular reactor

    2006-01-01

    The move of nuclear plant construction from the field to the factory for small, advanced pebble bed modular reactor (PBMR) designs has significant benefits compared to traditional light water reactor (LWR) field oriented designs. The use of modular factory construction techniques has a growing economic benefit over time through well-established process learning applications. This paper addresses the basic PBMR design objectives and commercialization model that drive this approach; provides a brief technical description of the PBMR design and layout with representative CAD views and discusses derived figures of merit highlighting the relative simplicity of PBMR compared to a modern LWR. The discussion emphasizes that more of PBMR can be built in the factory due to the simple design of a direct helium Brayton cycle compared to an indirect LWR steam cycle with its associated equipment. For the PBMR design there are fewer and less cumbersome auxiliary and safety systems with their attendant support requirements. Additionally, the labor force economic efficiency for nuclear projects is better in the factory than in the field, including consideration of labor costs and nuclear quality programs. Industrial learning is better in the factory because of the more controlled environment, mechanization optimization opportunities and because of the more stable labor force compared to the field. Supply chain benefits are more readily achievable with strategic contracts for module suppliers. Although building a nuclear power plant is not a typical high volume manufacturing process, for the PBMR-type of plant, with its high degree of standardization and relatively small, simplified design, the shift to factory work has a significant impact on overall project cost due to earlier identification and better coordination of parallel construction paths. This is in stark contrast to the construction of a large LWR in the past. Finally, the PBMR modular plant concept continues at the

    2003-01-01

    With recent advances in minimally invasive techniques, many surgeons are favoring laparoscopic over traditional "open" pyloromyotomy for hypertrophic pyloric stenosis. The results of few studies, however, exist in the literature adequately comparing surgical outcome. We present a retrospective analysis of 56 consecutive patients who underwent laparoscopic or open pyloromyotomy. A retrospective chart review of 56 consecutive infants (ages: 2 to 9 weeks; weights: 2.2 to 5.4 kilograms) who underwent laparoscopic (Group A-28) vs open (Group B- 28) pyloromyotomy between January 2000 and May 2001 was performed. Preoperative (age, sex, weight, HCO3, and K values) and postoperative (operating time, time to full feedings, persistence of emesis, and hospital stay) parameters were compared. Statistical analysis was performed via the Student t test and chi-square/Fischer analysis where appropriate. A P value 0.05). In Group A, 26/28 (92.9%) were completed successfully with 2 open conversions. Group A versus Group B average operating times (36.1 vs 32.5 minutes), time to full feedings (24.1 vs 27.0 hours), and hospital stay (2.5 vs 2.6 days) were similar (P>0.05). Persistent vomiting was observed in Group A, 25.0% (day 1)/3.5% (day 2) vs Group B, 39.3% (day 1)/10.7% (day 2). One infant in Group B required operative drainage of a wound abscess 1 week after surgery. Laparoscopic pyloromyotomy can be performed with similar efficiency and surgical outcome as traditional open pyloromyotomy. Improved cosmesis and avoidance of wound complications are major benefits of this procedure, and a tendency towards less postoperative emesis is a potential benefit that deserves further investigation.

    2014-06-01

    Taking notes on laptops rather than in longhand is increasingly common. Many researchers have suggested that laptop note taking is less effective than longhand note taking for learning. Prior studies have primarily focused on students' capacity for multitasking and distraction when using laptops. The present research suggests that even when laptops are used solely to take notes, they may still be impairing learning because their use results in shallower processing. In three studies, we found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. We show that whereas taking more notes can be beneficial, laptop note takers' tendency to transcribe lectures verbatim rather than processing information and reframing it in their own words is detrimental to learning. © The Author(s) 2014.

    Two-dimensional one-way coupled map lattices are used for cryptography where multiple space units produce chaotic outputs in parallel. One of the outputs plays the role of driving for synchronization of the decryption system while the others perform the function of information encoding. With this separation of functions the receiver can establish a self-checking and self-correction mechanism, and enjoys the advantages of both synchronous and self-synchronizing schemes. A comparison between the present system with the system of advanced encryption standard (AES) is presented in the aspect of channel noise influence. Numerical investigations show that our system is much stronger than AES against channel noise perturbations, and thus can be better used for secure communications with large channel noise.

    Freire, Sergio L S; Thorne, Nathaniel; Wutkowski, Michael; Dao, Selina

    2014-11-10

    Digital microfluidics (DMF), a technique for manipulation of droplets, is a promising alternative for the development of "lab-on-a-chip" platforms. Often, droplet motion relies on the wetting of a surface, directly associated with the application of an electric field; surface interactions, however, make motion dependent on droplet contents, limiting the breadth of applications of the technique. Some alternatives have been presented to minimize this dependence. However, they rely on the addition of extra chemical species to the droplet or its surroundings, which could potentially interact with droplet moieties. Addressing this challenge, our group recently developed Field-DW devices to allow the transport of cells and proteins in DMF, without extra additives. Here, the protocol for device fabrication and operation is provided, including the electronic interface for motion control. We also continue the studies with the devices, showing that multicellular, relatively large, model organisms can also be transported, arguably unaffected by the electric fields required for device operation.

    2016-01-01

    The emergence of Web 2.0 and Big Data technologies has allowed a new customer relationship strategy based on interactivity and collaboration called Social Customer Relationship Management (Social CRM) to be created. This enhances customer engagement and satisfaction. The implementation of Social CRM is a complex task that involves different organisational, human and technological aspects. However, there is a lack of methodologies to assist companies in these processes. This paper shows a novel methodology that helps companies to implement Social CRM, taking into account different aspects such as social customer strategy, the Social CRM performance measurement system, the Social CRM business processes, or the Social CRM computer system. The methodology was applied to one company in order to validate and refine it.

    Full Text Available The advantages of technology cannot be ignored and new technological applications come into our life almost every day. In this sense, it is inevitable to use those technological devices in the field of education for efficient teaching and learning. This paper deals with the attitudes of prep school students toward using Socrative in the classroom as a tool of response system in real time. Socrative is a smart student response system that enables instructors to discover or assess what students have learned in their lectures in real time. The study was conducted at the beginning of the second semester of 2014-2015 academic year in a university prep school. The survey was applied after the Socrative being practiced for a five-month period of first semester. The survey instrument which was previously used by Dervan (2014 was used to reveal students’ attitudes toward Socrative. The result of this study indicated that Socrative is a right tool that can help to improve users’ engagement in the classroom. Moreover, statistical analysis showed that there was no difference between the attitudes across gender.

    Percutaneous ultrasound-guided renal biopsy (RB) is the gold standard for diagnosis of renal diseases. The standard procedure involves biopsy in the prone position (PP) for the native kidneys. In high risk patients, transjugular and laparoscopic RB have been proposed. In patients suffering from obesity or respiratory diseases, the RB of the native kidney in the supine anterolateral position (SALP) represents an alternative to these invasive and expensive methods. We illustrate the technique of execution of RB in the lateral position (LP) on native kidneys. The procedure is safe, effective and has reduced the path travelled by the needle biopsy compared with PP and SALP.

    Full Text Available Tattooing process can be a painful experience whether achieving a permanent or temporary body art on skin, and there can be horrible consequences. By taking advantage of UV protection factor variables of fashion clothing materials, it is possible to create this kind of body art in a much healthier way. The material performance is key, besides UPF materials that relies on the material behaviour when combined, layer sequence of these materials used for the desired function is equally as important, if not, even more important so. When properly combined in the correct order, making use of the right technology it may be possible to test different combinations. The advantages are, besides creating a temporary tattoo, that the user can benefit from moderate sun bathing advantages, that can provide the desired body art design on skin and the sunbathing health benefits. All of this can only be possible with a deep understanding of the UV protection factor of fashion materials, and how it can be tested and used in the manufacturing process for the desired function.

  8. Size and shape of Brain may be such as to take advantage of two Dimensions of Time

    Science.gov (United States)

    Kriske, Richard

    2014-03-01

    This author had previously Theorized that there are two non-commuting Dimensions of time. One is Clock Time and the other is Information Time (which we generally refer to as Information, like Spin Up or Spin Down). When time does not commute with another Dimension of Time, one takes the Clock Time at one point in space and the Information time is not known; that is different than if one takes the Information time at that point and the Clock time is not known--This is not explicitly about time but rather space. An example of this non-commutation is that if one knows the Spin at one point and the Time at one point of space then simultaneosly, one knows the Spin at another point of Space and the Time there (It is the same time), it is a restatement of the EPR paradox. As a matter of fact two Dimensions of Time would prove the EPR paradox. It is obvious from that argument that if one needed to take advantage of Information, then a fairly large space needs to be used, a large amount of Energy needs to be Generated and a symmetry needs to be established in Space-like the lobes of a Brain in order to detect the fact that the Tclock and Tinfo are not Commuting. This Non-Commuting deposits a large amount of Information simultaneously in that space, and synchronizes the time there.

    Robin, Brett N; Lubowitz, James H

    2014-10-01

    Anterior cruciate ligament (ACL) femoral socket techniques have distinct advantages and disadvantages when considering the following techniques: transtibial, anteromedial portal, outside-in, and outside-in retroconstruction. There is no one perfect technique and we have an incomplete understanding of anatomical, biomechanical, isometry, stability, and clinical outcomes. Our primary focus is transtibial technique for creating the ACL femoral socket. Advantages include less invasive, isometric graft placement, stable Lachman exam, and minimal graft impingement with the tunnel and notch. Disadvantages include nonanatomic vertical graft placement that can cause rotational instability and positive pivot shift, interference screw divergence, graft-tunnel length mismatch, femoral socket constraint, posterior cruciate ligament impingement, and a short, oblique tibial tunnel that may undermine the medial plateau in an attempt to achieve anatomic ACL reconstruction.

    2018-02-01

    Full Text Available There are currently a number of imaging techniques available for evaluating the morphology of liposomes and other nanoparticles, with each having its own advantages and disadvantages that should be considered when interpreting data. Controlling and validating the morphology of nanoparticles is of key importance for the effective clinical translation of liposomal formulations. There are a number of physical characteristics of liposomes that determine their in vivo behavior, including size, surface characteristics, lamellarity, and homogeneity. Despite the great importance of the morphology of nanoparticles, it is generally not well-characterized and is difficult to control. Appropriate imaging techniques provide important details regarding the morphological characteristics of nanoparticles, and should be used in conjunction with other methods to assess physicochemical parameters. In this review, we will discuss the advantages and limitations of available imaging techniques used to evaluate liposomal formulations.

    Interventional techniques not only provide opportunity of treatment for many diseases, but also alter the traditional therapeutic pattern. With the new century of wide application of biological therapies, interventional technique also shows extensive roles. The current biological therapy, including gene therapy, cell transplantation therapy, immunobiologic molecule therapy containing cell factors, tumor antibody or vaccine, recombined proteins, radioactive-particles and targeting materials therapy, can be locally administrated by interventional techniques. The combination of targeting biological therapies and high-targeted interventional technique holds advantages of minimal invasion, accurate delivery, vigorous local effect, and less systemic adverse reactions. Authors believe that the biological therapy may arise a great opportunity for interventional radiology, therefore interventional colleagues should grasp firmly and promptly for the development and extension in this field.

    2014-12-01

    Sophisticated numerical tools exist for modeling geomorphic processes and linking them to tectonic and climatic systems, but they are often seen as inaccessible for users with an exploratory level of interest. We have improved the accessibility of landscape evolution models by producing a simple graphics user interface (GUI) that takes advantage of the Channel-Hillslope Integrated Landscape Development (CHILD) model. Model access is flexible: the user can edit values for basic geomorphic, tectonic, and climate parameters, or obtain greater control by defining the spatiotemporal distributions of those parameters. Users can make educated predictions by choosing their own parametric values for the governing equations and interpreting the results immediately through model graphics. This method of modeling allows users to iteratively build their understanding through experimentation. Use of this GUI is intended for inquiry and discovery-based learning activities. We discuss a number of examples of how the GUI can be used at the upper high school, introductory university, and advanced university level. Effective teaching modules initially focus on an inquiry-based example guided by the instructor. As students become familiar with the GUI and the CHILD model, the class can shift to more student-centered exploration and experimentation. To make model interpretations more robust, digital elevation models can be imported and direct comparisons can be made between CHILD model results and natural topography. The GUI is available online through the University of Maine's Earth and Climate Sciences website, through the Community Surface Dynamics Modeling System (CSDMS) model repository, or by contacting the corresponding author.

    Environmental pollution has been on the rise in the past few decades owing to increased human activities on energy reservoirs, unsafe agricultural practices and rapid industrialization. Amongst the pollutants that are of environmental and public health concerns due to their toxicities are: heavy metals, nuclear wastes, pesticides, green house gases, and hydrocarbons. Remediation of polluted sites using microbial process (bioremediation) has proven effective and reliable due to its eco-friendly features. Bioremediation can either be carried out ex situ or in situ, depending on several factors, which include but not limited to cost, site characteristics, type and concentration of pollutants. Generally, ex situ techniques apparently are more expensive compared to in situ techniques as a result of additional cost attributable to excavation. However, cost of on-site installation of equipment, and inability to effectively visualize and control the subsurface of polluted sites are of major concerns when carrying out in situ bioremediation. Therefore, choosing appropriate bioremediation technique, which will effectively reduce pollutant concentrations to an innocuous state, is crucial for a successful bioremediation project. Furthermore, the two major approaches to enhance bioremediation are biostimulation and bioaugmentation provided that environmental factors, which determine the success of bioremediation, are maintained at optimal range. This review provides more insight into the two major bioremediation techniques, their principles, advantages, limitations and prospects.

    2014-01-01

    Recent models on decision making under risk conditions have suggested that numerical abilities are important ingredients of advantageous decision-making performance, but empirical evidence is still limited. The results of our first study show that logical reasoning and basic mental calculation capacities predict ratio processing and that ratio processing predicts decision making under risk. In the second study, logical reasoning together with executive functions predicted probability processing (numeracy and probability knowledge), and probability processing predicted decision making under risk. These findings suggest that increasing an individual's understanding of ratios and probabilities should lead to more advantageous decisions under risk conditions.

    The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

  2. A symbiotic gas exchange between bioreactors enhances microalgal biomass and lipid productivities: taking advantage of complementary nutritional modes.

    2011-08-01

    This paper describes the association of two bioreactors: one photoautotrophic and the other heterotrophic, connected by the gas phase and allowing an exchange of O(2) and CO(2) gases between them, benefiting from a symbiotic effect. The association of two bioreactors was proposed with the aim of improving the microalgae oil productivity for biodiesel production. The outlet gas flow from the autotrophic (O(2) enriched) bioreactor was used as the inlet gas flow for the heterotrophic bioreactor. In parallel, the outlet gas flow from another heterotrophic (CO(2) enriched) bioreactor was used as the inlet gas flow for the autotrophic bioreactor. Aside from using the air supplied from the auto- and hetero-trophic bioreactors as controls, one mixotrophic bioreactor was also studied and used as a model, for its claimed advantage of CO(2) and organic carbon being simultaneously assimilated. The microalga Chlorella protothecoides was chosen as a model due to its ability to grow under different nutritional modes (auto, hetero, and mixotrophic), and its ability to attain a high biomass productivity and lipid content, suitable for biodiesel production. The comparison between heterotrophic, autotrophic, and mixotrophic Chlorella protothecoides growth for lipid production revealed that heterotrophic growth achieved the highest biomass productivity and lipid content (>22%), and furthermore showed that these lipids had the most suitable fatty acid profile in order to produce high quality biodiesel. Both associations showed a higher biomass productivity (10-20%), when comparing the two separately operated bioreactors (controls) which occurred on the fourth day. A more remarkable result would have been seen if in actuality the two bioreactors had been inter-connected in a closed loop. The biomass productivity gain would have been 30% and the lipid productivity gain would have been 100%, as seen by comparing the productivities of the symbiotic assemblage with the sum of the two

    Stone disease has afflicted mankind since centuries; records from ancient civilisations of India and Egypt have shown stones in human bodies. The scientific mind of humans has always made smart endeavours to remove the kidney stones. From large instruments made like the beaks of different animals and birds in 600 BC (Indian civilisation) to extremely sophisticated and miniaturised endoscopic intruments of today the human race has travelled a long way. The theme has always been to remove the stones with minimal morbidity and mortality and with minimum pain to the patient. The article takes you through the journey of instruments used in 600 BC until today. The story of instrumentation is a symbiosis of the medical minds along with engineering advances. The story of miniaturisation could not have moved further without the development of lasers, fiberoptics and sophisticated cameras. As the field stands today, we remove more complex stones by larger endoscopic intervention and smaller stones by miniaturised instruments. The article discusses all the merits and shortcomings of various techniques: from open surgery to standard PCNL to Mini PCNL to Ultra- Mini PCNL to Micro-PCNL.

  11. Elemental analyses of goundwater: demonstrated advantage of low-flow sampling and trace-metal clean techniques over standard techniques

    Science.gov (United States)

    Creasey, C. L.; Flegal, A. R.

    The combined use of both (1) low-flow purging and sampling and (2) trace-metal clean techniques provides more representative measurements of trace-element concentrations in groundwater than results derived with standard techniques. The use of low-flow purging and sampling provides relatively undisturbed groundwater samples that are more representative of in situ conditions, and the use of trace-element clean techniques limits the inadvertent introduction of contaminants during sampling, storage, and analysis. When these techniques are applied, resultant trace-element concentrations are likely to be markedly lower than results based on standard sampling techniques. In a comparison of data derived from contaminated and control groundwater wells at a site in California, USA, trace-element concentrations from this study were 2-1000 times lower than those determined by the conventional techniques used in sampling of the same wells prior to (5months) and subsequent to (1month) the collections for this study. Specifically, the cadmium and chromium concentrations derived using standard sampling techniques exceed the California Maximum Contaminant Levels (MCL), whereas in this investigation concentrations of both of those elements are substantially below their MCLs. Consequently, the combined use of low-flow and trace-metal clean techniques may preclude erroneous reports of trace-element contamination in groundwater. Résumé L'utilisation simultanée de la purge et de l'échantillonnage à faible débit et des techniques sans traces de métaux permet d'obtenir des mesures de concentrations en éléments en traces dans les eaux souterraines plus représentatives que les résultats fournis par les techniques classiques.

    Heated intraperitoneal chemotherapy (HIPEC) treats residual microscopic disease after cytoreductive surgery. In experimental models, the open HIPEC technique has shown a higher and more homogenous concentration of platinum in the peritoneum than achieved using the closed technique. A 25-cm H2O pressure enhances the penetration of oxaliplatin. Because pressure is easier to set up with the closed technique, high pressure may counterbalance the drawbacks of this technique versus open HIPEC, and a higher pressure may induce a higher penetration. Because higher concentration does not mean deeper penetration, a study of tissues beneath the peritoneum is required. Finally, achieving a deeper penetration (and a higher concentration) raises the question of the passage of drugs through the surgical glove and the surgeon's safety. Four groups of pigs underwent HIPEC with oxaliplatin (150 mg/L) for 30 minutes in open isobaric pressure and pressure at 25 cm H2O, and closed pressure at 25 and 40 cm H2O. Systemic absorption and peritoneal mapping of the concentration of platinum were analyzed, as well as in the retroperitoneal tissue and the surgical gloves. Blood concentrations were higher in open groups. In the parietal surfaces, the concentrations were not different between the isobaric and the closed groups (47.08, 56.39, and 48.57 mg/kg, respectively), but were higher in the open high-pressure group (85.93 mg/kg). In the visceral surfaces, they were lower in the closed groups (3.2 and 3.05 mg/kg) than in the open groups (7.03 and 9.56 mg/kg). Platinum concentrations were similar in the deep retroperitoneal tissue when compared between isobaric and high-pressure procedures. No platin was detected in the internal aspect of the gloves. The use of high pressure during HIPEC does not counterbalance the drawbacks of closed techniques. The tissue concentration of oxaliplatin achieved with the open techniques is higher, even if high pressure is applied during a closed technique

    Rotator cuff tear is a common finding in patients with painful, poorly functioning shoulders. The surgical management of this disorder has improved greatly and can now be fully arthroscopic. To evaluate clinical and radiological results of arthroscopic rotator cuff repair using 2 different techniques: single-row anchor fixation versus transosseous hardware-free suture repair. Randomized controlled trial; Level of evidence, 1. Sixty-nine patients with rotator cuff tears were enrolled: 35 patients were operated with metal anchors and 34 with standardized transosseous repair. The patients were clinically evaluated before surgery, during the 28 days after surgery, and at least 1 year after the operation by the use of validated rating scores (Constant score, QuickDASH, and numerical rating scale [NRS]). Final follow-up was obtained at more than 3 years by a QuickDASH evaluation to detect any difference from the previous follow-up. During the follow-up, rotator cuff integrity was determined through magnetic resonance imaging and was classified according to the 5 Sugaya categories. Patients operated with the transosseous technique had significantly less pain, especially from the 15th postoperative day: In the third week, the mean NRS value for the anchor group was 3.00 while that for transosseous group was 2.46 ( P = .02); in the fourth week, the values were 2.44 and 1.76, respectively ( P rotator cuff repair integrity, based on Sugaya magnetic resonance imaging classification, no significant difference was found between the 2 techniques in terms of retear rate ( P = .81). No significant differences were found between the 2 arthroscopic repair techniques in terms of functional and radiological results. However, postoperative pain decreased more quickly after the transosseous procedure, which therefore emerges as a possible improvement in the surgical repair of the rotator cuff.

  14. Advantages of the technique with segmented fields for tangential breast irradiation

    2013-01-01

    In the case of breast cancer, the prominent role of radiation therapy is an established fact. Depending on the stage of the disease, the breast is most often irradiated with two tangential fields and a direct supraclavicular field. Planning target volume is defined through the recommendations in ICRU Reports 50 and 62. The basic ‘dogma’ of radiotherapy requires the dose in the target volume to be homogenous. The favorable situation would be if the dose width was between 95% and 107%; this, however, is often not possible to be fulfilled. A technique for enhancement of homogeneity of isodose distribution would be using one or more additional fields, which will increase the dose in the volume where it is too low. These fields are called segmented fields (a technique also known as ‘field in field’) because they occupy only part of the primary fields. In this study we will show the influence of this technique on the dose homogeneity improvement in the PTV region. The mean dose in the target volume was increased from 49.51 Gy to 50.79 Gy in favor of the plans with segmented fields; and the dose homogeneity (measured in standard deviations) was also improved - 1.69 vs. 1.30. The increase in the target volume, encompassed by 95% isodose, was chosen as a parameter to characterize overall planning improvement. Thus, in our case, the improvement of dose coverage was from 93.19% to 97.06%. (Author)

  15. Ultrasound elastography: advantages, limitations and artefacts of the different techniques from a study on a phantom.

    Science.gov (United States)

    Franchi-Abella, S; Elie, C; Correas, J-M

    2013-05-01

    Ultrasound elastography is a technique currently under development. Its use in clinical practice is complicated because of the wide range of techniques used by the different manufacturers and the parameters proposed to characterise tissues. A comparative analysis on five ultrasound diagnostic systems has been performed on a calibrated elasticity phantom and demonstrated that: (1) all systems tested are reliable for simple qualitative analysis: is a nodule present and is it harder or softer than neighbouring tissues? (2) the deformation or hardness ratios between two regions are usually, however, not proportional to the theoretical ratios and only a binary analysis greater than 1 (harder) and less than 1 (softer) is reliable and could be used as a negative predictive value (NPV) for malignant lesions, as has been suggested by some authors; (3) finally, quantitative analysis using shear wave techniques performed variably, reliable measurements being obtained with only one of the systems. Measurements produced by these different systems must not be compared in clinical practice to monitor a patient and the threshold values proposed in the literature must only be used in an analysis carried out with the same system and same probe.

    2014-01-01

    In recent years, resections of midline skull base tumors have been conducted using endoscopic endonasal skull base (EESB) approaches. Nevertheless, many surgeons reported that cerebrospinal fluid (CSF) leakage is still a major complication of these approaches. Here, we report the results of our 42 EESB surgeries and discuss the advantages and limits of this approach for resecting various types of tumors, and also report our technique to overcome CSF leakage. All 42 cases involved midline skull base tumors resected using the EESB technique. Dural incisions were closed using nasoseptal flaps and fascia patch inlay sutures. Total removal of the tumor was accomplished in seven pituitary adenomas (33.3%), five craniopharyngiomas (62.5%), five tuberculum sellae meningiomas (83.3%), three clival chordomas (100%), and one suprasellar ependymoma. Residual regions included the cavernous sinus, the outside of the intracranial part of the internal carotid artery, the lower lateral part of the posterior clivus, and the posterior pituitary stalk. Overall incidence of CSF leakage was 7.1%. Even though the versatility of the approach is limited, EESB surgery has many advantages compared to the transcranial approach for managing mid-line skull base lesions. To avoid CSF leakage, surgeons should have skills and techniques for complete closure, including use of the nasoseptal flap and fascia patch inlay techniques.

    Traditional survey methods, which are generally costly and time-consuming, usually provide information at the regional or national level only. The utilization of lot quality assurance sampling (LQAS) methodology, developed in industry for quality control, makes it possible to use small sample sizes when conducting surveys in small geographical or population-based areas (lots). This article describes the practical use of LQAS for conducting health surveys to monitor health programmes in developing countries. Following a brief description of the method, the article explains how to build a sample frame and conduct the sampling to apply LQAS under field conditions. A detailed description of the procedure for selecting a sampling unit to monitor the health programme and a sample size is given. The sampling schemes utilizing LQAS applicable to health surveys, such as simple- and double-sampling schemes, are discussed. The interpretation of the survey results and the planning of subsequent rounds of LQAS surveys are also discussed. When describing the applicability of LQAS in health surveys in developing countries, the article considers current limitations for its use by health planners in charge of health programmes, and suggests ways to overcome these limitations through future research. It is hoped that with increasing attention being given to industrial sampling plans in general, and LQAS in particular, their utilization to monitor health programmes will provide health planners in developing countries with powerful techniques to help them achieve their health programme targets.

    This paper investigates the impact of trade openness on CO2 emissions using time series data over the period of 1970QI-2011QIV for Malaysia. We disintegrate the trade effect into scale, technique, composition, and comparative advantage effects to check the environmental consequence of trade at four different transition points. To achieve the purpose, we have employed augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests in order to examine the stationary properties of the variables. Later, the long-run association among the variables is examined by applying autoregressive distributed lag (ARDL) bounds testing approach to cointegration. Our results confirm the presence of cointegration. Further, we find that scale effect has positive and technique effect has negative impact on CO2 emissions after threshold income level and form inverted U-shaped relationship-hence validates the environmental Kuznets curve hypothesis. Energy consumption adds in CO2 emissions. Trade openness and composite effect improve environmental quality by lowering CO2 emissions. The comparative advantage effect increases CO2 emissions and impairs environmental quality. The results provide the innovative approach to see the impact of trade openness in four sub-dimensions of trade liberalization. Hence, this study attributes more comprehensive policy tool for trade economists to better design environmentally sustainable trade rules and agreements.

    Full Text Available It is often said that the worst pen is better than the best memory and regardless of how good the students' memory might be, they need to take notes during the lesson or lecture because it is impossible to remember all the details later on. This is so easy to use technique which requires a brief record of important information can help students not only recall what has been said in the class, but also to achieve their learning goals and provide a useful summary of the material to be revised especially before the test. Unfortunately, it is noticed that most of the students, especially at the secondary stage, neglect this important skill. Most of them don’t often write notes unless they are told to do so by the teacher or depend only on the textbooks forgetting that not all the material mentioned during the lesson found in them as some are explanations to the complex and abstract ones and others are related to the teacher's experience in the subject matter. In fact, note taking skill is part of the learning process and to be useful, students need to learn how to do it effectively and what to record because not all what is said is important. This requires acquiring more than one skill on the part of the learners and more effort on the part of the teacher to teach them how to do it properly. For the above reasons, more light will be shed in this research on this topic followed by an experiment and a test to evaluate its effectiveness in learning

  20. The Advantages of an Attenuated Total Internal Reflection Infrared Microspectroscopic Imaging Technique for the Analysis of Polymer Laminates.

    Ling, Chen; Sommer, André J

    2015-06-01

    Until recently, the analysis of polymer laminates using infrared microspectroscopy involved the painstaking separation of individual layers by dissection or by obtaining micrometer thin cross-sections. The latter usually requires the expertise of an individual trained in microtomy and even then, the very structure of the laminate could affect the outcome of the spectral results. The recent development of attenuated total internal reflection (ATR) infrared microspectroscopy imaging has provided a new avenue for the analysis of these multilayer structures. This report compares ATR infrared microspectroscopy imaging with conventional transmission infrared microspectroscopy imaging. The results demonstrate that the ATR method offers improved spatial resolution, eliminates a variety of competing optical processes, and requires minimal sample preparation relative to transmission measurements. These advantages were illustrated using a polymer laminate consisting of 11 different layers whose thickness ranged in size from 4-20 μm. The spatial resolution achieved by using an ATR-FTIR (Fourier transform infrared spectroscopy) imaging technique was diffraction limited. Contrast in the ATR images was enhanced by principal component analysis.

    The historical and economic involvement of Brazil with tobacco, as a major producer and exporter, was considered an insurmountable obstacle to controlling the consumption of this product. Nevertheless, the country was able to achieve significant progress in implementing public policies and to take an international leadership position, meeting its constitutional commitment to protect public health. In this paper we provide a brief historical overview of tobacco control (TC) in Brazil, and analyse the factors that contributed to the major decline in tobacco consumption in the country over the last 20 years, as well as identify the challenges that had to be overcome and those still at play. The Brazilian case demonstrates how cross-sectorial collaborations among health-related groups that capitalize on their respective strengths and capacities can help to influence public policy and overcome industry and population resistance to change. Although Brazil still lags behind some leading TC nations, the country has an extensive collaborative TC network that was built over time and continues to focus upon this issue. The tobacco experience can serve as an example for other fields, such as alcoholic beverages, of how networks can be formed to influence the legislative process and the development of public policies. Brazilian statistics show that problems related to non-communicable diseases are a pressing public health issue, and advocacy groups, policy-makers and government departments can benefit from tobacco control history to fashion their own strategies. © 2013 Society for the Study of Addiction.

  7. Taking advantage of HTML5 browsers to realize the concepts of session state and workflow sharing in web-tool applications

    2013-12-01

    Scientists prefer not having to be tied down to a specific machine or operating system in order to analyze local and remote data sets or publish work. Increasingly, analysis has been migrating to decentralized web services and data sets, using web clients to provide the analysis interface. While simplifying workflow access, analysis, and publishing of data, the move does bring with it its own unique set of issues. Web clients used for analysis typically offer workflows geared towards a single user, with steps and results that are often difficult to recreate and share with others. Furthermore, workflow results often may not be easily used as input for further analysis. Older browsers further complicate things by having no way to maintain larger chunks of information, often offloading the job of storage to the back-end server or trying to squeeze it into a cookie. It has been difficult to provide a concept of "session storage" or "workflow sharing" without a complex orchestration of the back-end for storage depending on either a centralized file system or database. With the advent of HTML5, browsers gained the ability to store more information through the use of the Web Storage API (a browser-cookie holds a maximum of 4 kilobytes). Web Storage gives us the ability to store megabytes of arbitrary data in-browser either with an expiration date or just for a session. This allows scientists to create, update, persist and share their workflow without depending on the backend to store session information, providing the flexibility for new web-based workflows to emerge. In the DSASWeb portal ( http://cida.usgs.gov/DSASweb/ ), using these techniques, the representation of every step in the analyst's workflow is stored as plain-text serialized JSON, which we can generate as a text file and provide to the analyst as an upload. This file may then be shared with others and loaded back into the application, restoring the application to the state it was in when the session file

    Highlights: Black-Right-Pointing-Pointer Information from successive self-nucleation and annealing technique is analyzed. Black-Right-Pointing-Pointer Oxygen and antioxidants reduce crosslinking efficiency by reaction with free radicals. Black-Right-Pointing-Pointer Recognizable differences are obtained in samples irradiated at different atmospheres. - Abstract: Information obtained from successive self-nucleation and annealing (SSA) technique is analyzed, paying special attention to the observable effects of samples thickness and antioxidant and oxygen concentrations. Molecular structure changes for low density polyethylene (LDPE) samples, irradiated under three different atmospheres for doses between 33 and 222 kGy were analyzed, with emphasis on the changes of longer polymethylene crystallizable lengths. Antioxidant and oxygen concentrations were varied for samples of different thickness to study the effects on degradation. The changes in the molecular structure were followed simultaneously by SSA and Infrared spectroscopy (FTIR) via carbonyl group concentration. Preliminary quantifications of the SSA technique sensitivity are also advanced.

    1992-05-01

    Technetium (Tc) was the first artificially created by man and has no stable isotope. The most crucial technetium isotope environmentally /sup 99/Tc is a pure beta emitter with a half-life of 2.1 X 105 years. The main source of /sup 99/Tc to the environment is the disposal of liquid wastes from nuclear installations or during separation and recovery of spent nuclear fuels. Because of its long half life, high fission yield, mobility and current interest in the collective long term doses, it is necessary to establish a knowledge of the behavior of /sup 99/Tc in the environment for complete assessment of the impact of nuclear industry. Due to various analytical difficulties however, data on the behavior of Tc in the environment are limited. In the literature, many techniques are reported for the analysis of Tc. A very sensitive, precise and powerful technique is required which can be applied to environmental samples in order to gain information by obtaining more precise data to assess the impact of Tc releases on man. Attention has been focussed for this purpose on a new powerful technique i.e. inductively coupled plasma mass spectrometry (ICP-MS). This report has been directed towards the development of ICP-MS. The technique gives a very high sensitivity enabling long lived radionuclides including /sup 99/Tc to be measured directly down to pg ml-1 levels in solution. Because of its versatility ICP-MS is finding applications for trace multielement analysis and low detection limits in almost all fields. (author)

  12. MEMS Technology Sensors as a More Advantageous Technique for Measuring Foot Plantar Pressure and Balance in Humans

    Directory of Open Access Journals (Sweden)

    Clara Sanz Morère

    2016-01-01

    Full Text Available Locomotor activities are part and parcel of daily human life. During walking or running, feet are subjected to high plantar pressure, leading sometimes to limb problems, pain, or foot ulceration. A current objective in foot plantar pressure measurements is developing sensors that are small in size, lightweight, and energy efficient, while enabling high mobility, particularly for wearable applications. Moreover, improvements in spatial resolution, accuracy, and sensitivity are of interest. Sensors with improved sensing techniques can be applied to a variety of research problems: diagnosing limb problems, footwear design, or injury prevention. This paper reviews commercially available sensors used in foot plantar pressure measurements and proposes the utilization of pressure sensors based on the MEMS (microelectromechanical systems technique. Pressure sensors based on this technique have the capacity to measure pressure with high accuracy and linearity up to high pressure levels. Moreover, being small in size, they are highly suitable for this type of measurement. We present two MEMS sensor models and study their suitability for the intended purpose by performing several experiments. Preliminary results indicate that the sensors are indeed suitable for measuring foot plantar pressure. Importantly, by measuring pressure continuously, they can also be utilized for body balance measurements.

  14. The advantages, and challenges, in using multiple techniques in the estimation of surface water-groundwater fluxes.

    Science.gov (United States)

    Shanafield, M.; Cook, P. G.

    2014-12-01

    When estimating surface water-groundwater fluxes, the use of complimentary techniques helps to fill in uncertainties in any individual method, and to potentially gain a better understanding of spatial and temporal variability in a system. It can also be a way of preventing the loss of data during infrequent and unpredictable flow events. For example, much of arid Australia relies on groundwater, which is recharged by streamflow through ephemeral streams during flood events. Three recent surface water/groundwater investigations from arid Australian systems provide good examples of how using multiple field and analysis techniques can help to more fully characterize surface water-groundwater fluxes, but can also result in conflicting values over varying spatial and temporal scales. In the Pilbara region of Western Australia, combining streambed radon measurements, vertical heat transport modeling, and a tracer test helped constrain very low streambed residence times, which are on the order of minutes. Spatial and temporal variability between the methods yielded hyporheic exchange estimates between 10-4 m2 s-1 and 4.2 x 10-2 m2 s-1. In South Australia, three-dimensional heat transport modeling captured heterogeneity within 20 square meters of streambed, identifying areas of sandy soil (flux rates of up to 3 m d-1) and clay (flux rates too slow to be accurately characterized). Streamflow front modeling showed similar flux rates, but averaged over 100 m long stream segments for a 1.6 km reach. Finally, in central Australia, several methods are used to decipher whether any of the flow down a highly ephemeral river contributes to regional groundwater recharge, showing that evaporation and evapotranspiration likely accounts for all of the infiltration into the perched aquifer. Lessons learned from these examples demonstrate the influences of the spatial and temporal variability between techniques on estimated fluxes.

    Objective: To study the scanning technique of 16-detector multic-slice spiral CT(MSCT) for combined pulmonary artery and deep vein of lower limb in pulmonary thromboembolism (PE) patients. Methods: Forty suspected pulmonary thromboembolism patients were performed both pulmonary artery angiography (CTA) and indirect deep vein venography (CTV) on 16-detector MSCT. The parameters of the latter as following: total contrast volume 120-150 ml, injection rate 4.0-4.5 ml/s (from antecubital vein), delay time 4.0 for CTA 20-23 s, CTV 120-180 s, collimation for CTA 1.25 mm and 0.625 mm, CTV 2.5 mm, scan range of CTV: from popliteal vein to the level of bilateral renal vein into the inferior vena cava. Postprocessing include MPR, MIP, and VR. The test was used to analyzed the images. Results: Twenty five patients had both pulmonary thromboembolism (PE) and deep vein thromboembolism (DVT), 8 patients had only DVT, 2 had only PE, and 5 had neither. There was no difference between different collimation in depicting thrombus. The CT value number of enhanced pulmonary artery and lower deep vein was obviously higher than the thrombus. The value of MPR, MIP, VR for PE was 100%, 100%, and 65%, The value of MPR, MIP, VR for DVT is 100%, 60%, and 50%. Conclusion: The technique of combined pulmonary CTA and deep vein CTV of 16-detector MSCT will provide a new modality for pulmonary thromboembolism patients. (author)

    2017-04-01

    Major progress has been made in breast cancer reconstruction surgery. The standard technique for totally implanted vascular access device (TIVAD) implantation generally requires an incision for port insertion on the anterior part of the thorax that leaves a scar in the middle of the neckline in patients who have undergone mastectomy with complex breast reconstruction. The aim of this technical note is to report our revised surgical technique for TIVAD placement. In patients with breast cancer, we take a lateralized approach, performing an oblique incision on the lowest part of the deltopectoral groove. This allows us to introduce the port and to place it on the anterolateral part of the thorax, thus avoiding an unaesthetic scar on the anterior part of the thorax. Our modified technique for TIVAD implantation is described.

    Full Text Available High-resolution sensor Surface Reflectance (SR data are affected by surface anisotropy but are difficult to adjust because of the low temporal frequency of the acquisitions and the low angular sampling. This paper evaluates five high spatial resolution Bidirectional Reflectance Distribution Function (BRDF adjustment techniques. The evaluation is based on the noise level of the SR Time Series (TS corrected to a normalized geometry (nadir view, 45° sun zenith angle extracted from the multi-angular acquisitions of SPOT4 over three study areas (one in Arizona, two in France during the five-month SPOT4 (Take5 experiment. Two uniform techniques (Cst, for Constant, and Av, for Average, relying on the Vermote–Justice–Bréon (VJB BRDF method, assume no variation in space of the BRDF shape. Two methods (VI-dis, for NDVI-based disaggregation and LC-dis, for Land-Cover based disaggregation are based on disaggregation of the MODIS-derived BRDF VJB parameters using vegetation index and land cover, respectively. The last technique (LUM, for Look-Up Map relies on the MCD43 MODIS BRDF products and a crop type data layer. The VI-dis technique produced the lowest level of noise corresponding to the most effective adjustment: reduction from directional to normalized SR TS noises by 40% and 50% on average, for red and near-infrared bands, respectively. The uniform techniques displayed very good results, suggesting that a simple and uniform BRDF-shape assumption is good enough to adjust the BRDF in such geometric configuration (the view zenith angle varies from nadir to 25°. The most complex techniques relying on land cover (LC-dis and LUM displayed contrasting results depending on the land cover.

  1. What is the difference in the hybrid imaging techniques - SPECT/CT and PET-CT and is there any advantage of their application?

    International Nuclear Information System (INIS)

    Kostadinova, I.

    2012-01-01

    The hybrid imaging methods - Single Photon Emission Tomography-Computer Tomography /SPECT-CT / and Positron Emission Tomography-Computer Tomography / PET-CT/ allow receiving of combined image of two different techniques. In such a way it is possible to superimpose detailed anatomical image of the multislice spiral computer tomography with specific and sensitive molecular images of the SPECT and PET in a single study, allowing utilization of the full possibilities of the both techniques. They have advantages and disadvantages, which basically stem from the differences in the used radiopharmaceuticals and their physical properties. In PET- CT - positron emitters are applied, most often 18F and 11C, while in SPECT-CT - single photon emitters, most often 99m Tc and 131 I. A disadvantage of PET is a high cost, which is produced in cyclotron and its logistics is complicated. The great advantage of PET is its better spatial resolution, compared to SPECT, because of the possibility for simultaneous detection of pared photons and better registration. These techniques, especially PET-CT are nowadays the most increasing imaging methods in the world in making diagnosis, staging and following the effect of treatment in patients with oncological, neurological, cardiological, orthopedic diseases and infections. Recently, they are applied for the purposes of radiotherapy planning on the basis of the metabolically active tumor. As a final result, compared to the conventional techniques - roentgenography, CT and MRI, it is possible in many cases to make an early and more precise diagnosis, saving patients' time and using most appropriate treatment. As a conclusion it is clear, that the hybrid imaging has future and its application will increase. (author)

  2. Imaging with organic indicators and high-speed charge-coupled device cameras in neurons: some applications where these classic techniques have advantages.

    Ross, William N; Miyazaki, Kenichi; Popovic, Marko A; Zecevic, Dejan

    2015-04-01

    Dynamic calcium and voltage imaging is a major tool in modern cellular neuroscience. Since the beginning of their use over 40 years ago, there have been major improvements in indicators, microscopes, imaging systems, and computers. While cutting edge research has trended toward the use of genetically encoded calcium or voltage indicators, two-photon microscopes, and in vivo preparations, it is worth noting that some questions still may be best approached using more classical methodologies and preparations. In this review, we highlight a few examples in neurons where the combination of charge-coupled device (CCD) imaging and classical organic indicators has revealed information that has so far been more informative than results using the more modern systems. These experiments take advantage of the high frame rates, sensitivity, and spatial integration of the best CCD cameras. These cameras can respond to the faster kinetics of organic voltage and calcium indicators, which closely reflect the fast dynamics of the underlying cellular events.

  3. R&D INVESTMENTS AND SPILLOVERS UNDER ENDOGENOUS ABSORPTIVE CAPACITY: COMPETITIVE R&D CANNOT TAKE FULL-ADVANTAGE OF COMPLEMENTARITY IN ABSORPTIVE CAPACITY WHILE COOPERATIVE R&D CAN

    Directory of Open Access Journals (Sweden)

    Mário A.P.M. Da Silva

    2018-03-01

    Full Text Available We show that the setting up of general conditions on complementarity in absorptive capacity gives rise to different, if not opposite Nash equilibrium outcomes to those found when absorptive capacity is assumed to be determined only by the similarity of R&D orientations. Firms that cooperate in R&D can take full-advantage of complementarity in R&D by adopting firm-specific R&D paths, which appears to contradict findings and predictions of existing theoretical literature on R&D and spillovers. Oddly, firms competing in R&D cannot gain the most from the potential of complementarity in knowledge by not choosing firm-specific R&D approaches in equilibrium under even milder conditions, which is contrary to another prediction of existing related models.

    For centuries, techniques used to manipulate joints in the spine have been passed down from one generation of manipulators to the next. Today, spinal manipulation is in the curious position that positive clinical effects have now been demonstrated, yet the theoretical base underpinning every aspect of its use is still underdeveloped. An important question is posed in this masterclass: why do spinal manipulation techniques take the form they do? From the available literature, two factors appear to provide an answer: 1. Action of a force upon vertebrae. Any 'direct' spinal manipulation technique requires that the patient be orientated in such a way that force is applied perpendicular to the overlying skin surface so as to act upon the vertebrae beneath. If the vertebral motion produced by 'directly' applied force is insufficient to produce the desired effect (e.g. cavitation), then force must be applied 'indirectly', often through remote body segments such as the head, thorax, abdomen, pelvis, and extremities. 2. Spinal segment morphology. A new hypothesis is presented. Spinal manipulation techniques exploit the morphology of vertebrae by inducing rotation at a spinal segment, about an axis that is always parallel to the articular surfaces of the constituent zygapophysial joints. In doing so, the articular surfaces of one zygapophysial joint appose to the point of contact, resulting in migration of the axis of rotation towards these contacting surfaces, and in turn this facilitates gapping of the other (target) zygapophysial joint. Other variations in the form of spinal manipulation techniques are likely to depend upon the personal style and individual choices of the practitioner.

    Full text: The ageing process through its complex mechanisms affects in time more or less the component parts, the systems and the structures of the nuclear power plant. For CANDU type nuclear power plant the main component part in operation is the pressure tube, made from Zr - 2,5% Nb alloy, used in extreme hard operation conditions (static and dynamic loading from high pressure and temperature and high neutron flux). The pressure tube endures, in time, changing of the material and of the geometry. Additionally, the excessive hydrogen uptake initiates the Delayed Hydride Cracking (DHC) mechanism on the pressure tubes. For checking the evolution of the hydride / deuteration phenomena in the material of the pressure tube and especially to establish the real lifetime as compared to design lifetime it is useful to initiate, develop and apply a technology and a complex equipment for taking samples directly from inside the pressure tube, this enabling the determination of the hydrogen content. In the paper are showed briefly: - the evolution in time of the techniques for axial taking of the samples from inside of the pressure tube used in the CANDU 6 NPP; - the reasons that determined us to develop one of these technologies; - the technological facilities needed to apply it.

  7. New Scientific Contribution on the 2-D Subdomain Technique in Polar Coordinates: Taking into Account of Iron Parts

    Directory of Open Access Journals (Sweden)

    Frédéric Dubas

    2017-10-01

    Full Text Available This paper presents a new scientific contribution to the two-dimensional red(2-D subdomain technique in polar coordinates taking into account the finite relative permeability of the ferromagnetic material. The constant relative permeability corresponds to the linear part of the nonlinear B ( H curve. As in the conventional technique, the separation of variables method and the Fourier series are used for the resolution of magnetostatic Maxwell equations in each region. The general solutions of the magnetic field in subdomains, as well as the boundary conditions (BCs between regions are different from the conventional method. In the proposed method, the magnetic field solution in each subdomain is a superposition of two magnetic quantities in the two directions (i.e., r- and Θ -axis, and the BCs between two regions are also in both directions. For example, the scientific contribution has been applied to an air- or iron-cored coil supplied by a constant current. The distribution of local quantities (i.e., the magnetic vector potential and flux density has been validated by a corresponding 2-D finite-element analysis (FEA. The obtained semi-analytical results are in very good agreement with those of the numerical method.

    2018-07-01

    In 2015, the Bundeswehr Institute of Radiobiology organized a North Atlantic Treaty Organization exercise to examine the significance of clinical signs and symptoms for the prediction of late-occurring acute radiation syndrome. Cases were generated using either the Medical Treatment Protocols for Radiation Accident Victims (METREPOL, n = 167) system or using real-case descriptions extracted from a database system for evaluation and archiving of radiation accidents based on case histories (SEARCH, n = 24). The cases ranged from unexposed [response category 0 (RC 0, n = 89)] to mild (RC 1, n = 45), moderate (RC 2, n = 19), severe (RC 3, n = 20), and lethal (RC 4, n = 18) acute radiation syndrome. During the previous exercise, expert teams successfully predicted hematological acute radiation syndrome severity, determined whether hospitalization was required, and gave treatment recommendations, taking advantage of different software tools developed by the North Atlantic Treaty Organization teams. The authors provided the same data set to radiobiology students who were introduced to the medical management of acute effects after radiation exposure and the software tools during a class lasting 15 h. Corresponding to the previous results, difficulties in the discrimination between RC 0/RC 1 and RC 3/RC 4, as well as a systematic underestimation of RC 1 and RC 2, were observed. Nevertheless, after merging reported response categories into clinically relevant groups (RC 0-1, RC 2-3, and RC 3-4), it was found that the majority of cases (95.2% ± 2.2 standard deviations) were correctly identified and that 94.7% (±2.6 standard deviations) developing acute radiation syndrome and z96.4% (±1.6 standard deviations) requiring hospitalization were identified correctly. Two out of three student teams also provided a dose estimate. These results are comparable to the best-performing team of the 2015 North Atlantic Treaty Organization exercise (response category: 92.5%; acute

  14. Advantages of active love wave techniques in geophysical characterizations of seismographic station - Case studies in California and the central and eastern United States

    Martin, Antony; Yong, Alan K.; Salomone, Larry A.

    2014-01-01

    Active-source Love waves, recorded by the multi-channel analysis of surface wave (MASLW) technique, were recently analyzed in two site characterization projects. Between 2010 and 2012, the 2009 American Recovery and Reinvestment Act (ARRA) funded GEOVision to conduct geophysical investigations at 191 seismographic stations in California and the Central Eastern U.S. (CEUS). The original project plan was to utilize active and passive Rayleigh wave-based techniques to obtain shear-wave velocity (VS) profiles to a minimum depth of 30 m and the time-averaged VS of the upper 30 meters (VS30). Early in this investigation it became clear that Rayleigh wave techniques, such as multi-channel analysis of surface waves (MASRW), were not suited for characterizing all sites. Shear-wave seismic refraction and MASLW techniques were therefore applied. In 2012, the Electric Power Research Institute funded characterization of 33 CEUS station sites. Based on experience from the ARRA investigation, both MASRW and MASLW data were acquired by GEOVision at 24 CEUS sites. At shallow rock sites, sites with steep velocity gradients, and, sites with a thin, low velocity, surficial soil layer overlying stiffer sediments, Love wave techniques generally were found to be easier to interpret, i.e., Love wave data typically yielded unambiguous fundamental mode dispersion curves and thus, reduce uncertainty in the resultant VS model. These types of velocity structure often excite dominant higher modes in Rayleigh wave data, but not in the Love wave data. It is possible to model Rayleigh wave data using multi- or effective-mode techniques; however, extraction of Rayleigh wave dispersion data was found to be difficult in many cases. These results imply that field procedures should include careful scrutiny of Rayleigh wave-based dispersion data in order to also collect Love wave data when warranted.

    Recent advances in catalysis instrumentations include synchrotron-based facilities where time-resolved X-ray scattering and absorption techniques are combined in the same in situ or operando experiment to study catalysts at work. To evaluate the advances and limitations of this method, we performed a series of experiments at the new XAFS/XRD instrument in the National Synchrotron Light Source. Nearly simultaneous X-ray diffraction (XRD) and X-ray absorption fine-structure (XAFS) measurements of structure and kinetics of several catalysts under reducing or oxidizing conditions have been performed and carefully analyzed. For CuFe 2 O 4 under reducing conditions, the combined use of the two techniques allowed us to obtain accurate data on kinetics of nucleation and growth of metallic Cu. For the inverse catalyst CuO/CeO 2 that underwent isothermal reduction (with CO) and oxidation (with O 2 ), the XAFS data measured in the same experiment with XRD revealed strongly disordered Cu species that went undetected by diffraction. These and other examples emphasize the unique sensitivity of these two complementary methods to follow catalytic processes in the broad ranges of length and time scales.

This paper reviews some of the practical advantages to using evolutionary algorithms as compared with classic methods of optimization or artificial intelligence. Specific advantages include the flexibility of the procedures, as well as their ability to self-adapt the search for optimum solutions on the fly. As desktop computers increase in speed, the application of evolutionary algorithms will become routine.

    Piezoelectric composites comprising an active phase of ferroelectric ceramic and a polymer matrix have recently found numerous sensory applications. However, it remains a major challenge to further improve their electromechanical response for advanced applications such as precision control and monitoring systems. We here investigated the incorporation of graphene platelets (GnPs) and multi-walled carbon nanotubes (MWNTs), each with various weight fractions, into PZT (lead zirconate titanate)/epoxy composites to produce three-phase nanocomposites. The nanocomposite films show markedly improved piezoelectric coefficients and electromechanical responses (50%) besides an enhancement of ~200% in stiffness. The carbon nanomaterials strengthened the impact of electric field on the PZT particles by appropriately raising the electrical conductivity of the epoxy. GnPs have been proved to be far more promising in improving the poling behavior and dynamic response than MWNTs. The superior dynamic sensitivity of GnP-reinforced composite may be caused by the GnPs' high load transfer efficiency arising from their two-dimensional geometry and good compatibility with the matrix. The reduced acoustic impedance mismatch resulting from the improved thermal conductance may also contribute to the higher sensitivity of GnP-reinforced composite. This research pointed out the potential of employing GnPs to develop highly sensitive piezoelectric composites for sensing applications.

    Given the rising profile of the Alexander Technique in the UK, there is a need for a comprehensive description of its teachers and of those who currently take lessons. In a national survey of Alexander teachers, we set out to address this information gap. A cross-sectional survey of 871 UK members of three main Alexander Technique teachers' professional associations was conducted. A questionnaire requested information about their professional background, teaching practice and methods, and about the people who attend lessons and their reasons for seeking help. With an overall response rate of 61%, 534 teachers responded; 74% were female with median age of 58 years, 60% had a higher education qualification, and 95% were self-employed, many with additional non-Alexander paid employment. The majority (87%) offered lessons on their own premises or in a privately rented room, and 19% provided home visits; both individual and group lessons were provided. People who took lessons were predominantly female (66%) with a median age of 48 years, and 91% paid for their lessons privately. Nearly two-thirds (62%) began lessons for reasons related to musculoskeletal conditions, including back symptoms, posture, neck pain, and shoulder pain. Other reasons were general (18%, including well-being), performance-related (10%, including voice-, music-, and sport-related), psychological (5%) and neurological (3%). We estimate that Alexander teachers in the UK provide approximately 400,000 lessons per year. This study provides an overview of Alexander Technique teaching in the UK today and data that may be useful when planning future research. Copyright © 2015 Elsevier Ltd. All rights reserved.

However, in the absence of gating device or without the possibility to use it, the 3-volume method allowed to take into account more precisely the organ motion than the classical technique. Conclusion: The 3-volume method can be done. It is a good method to take into account the organ motions. However, the gating-like method gives the best results leading to propose its use even for pre-operative patients with upper tumors. (authors)

  16. COMPETITIVE PRODUCT ADVANTAGES

    Directory of Open Access Journals (Sweden)

    Adrian MICU

    2006-01-01

    Full Text Available Cost advantages may be either internal or external. Internal economics of scope, scale, or experience, and external economies of focus or logistical integration, enable a company to produce some products at a lower cost than the competition. The coordination of pricing with suppliers, although not actually economizing resources, can improve the efficiency of pricing by avoiding the incrementalization of a supplier's nonincremental fixed costs and profit. Any of these strategies can generate cost advantages that are, at least in the short run, sustainable. Even cost advantages that are not sustainable, however, can generate temporary savings that are often the key to building more sustainable cost or product advantages later.. Even when a product's physical attributes are not readily differentiable, opportunities to develop product advantages remain. The augmented product that customers buy is more than the particular product or service exchanged. It includes all sorts of ancillary services and intangible relationships that make buying thesame product from one company less difficult, less risky, or more pleasant than buying from a competitor. Superior augmentation of the same basic product can add substantial value in the eyes of consumers, leading them to pay willingly what are often considerable price premiums.

    1998-01-01

    What differentiates truly great corporate strategies from the merely adequate? How can executives at the corporate level create tangible advantage for their businesses that makes the whole more than the sum of the parts? This article presents a comprehensive framework for value creation in the multibusiness company. It addresses the most fundamental questions of corporate strategy: What businesses should a company be in? How should it coordinate activities across businesses? What role should the corporate office play? How should the corporation measure and control performance? Through detailed case studies of Tyco International, Sharp, the Newell Company, and Saatchi and Saatchi, the authors demonstrate that the answers to all those questions are driven largely by the nature of a company's special resources--its assets, skills, and capabilities. These range along a continuum from the highly specialized at one end to the very general at the other. A corporation's location on the continuum constrains the set of businesses it should compete in and limits its choices about the design of its organization. Applying the framework, the authors point out the common mistakes that result from misaligned corporate strategies. Companies mistakenly enter businesses based on similarities in products rather than the resources that contribute to competitive advantage in each business. Instead of tailoring organizational structures and systems to the needs of a particular strategy, they create plain-vanilla corporate offices and infrastructures. The company examples demonstrate that one size does not fit all. One can find great corporate strategies all along the continuum.

    Plaut, Alfred B J

    2005-02-01

    In this paper the author explores the theoretical and technical issues relating to taking notes of analytic sessions, using an introspective approach. The paper discusses the lack of a consistent approach to note taking amongst analysts and sets out to demonstrate that systematic note taking can be helpful to the analyst. The author describes his discovery that an initial phase where as much data was recorded as possible did not prove to be reliably helpful in clinical work and initially actively interfered with recall in subsequent sessions. The impact of the nature of the analytic session itself and the focus of the analyst's interest on recall is discussed. The author then describes how he modified his note taking technique to classify information from sessions into four categories which enabled the analyst to select which information to record in notes. The characteristics of memory and its constructive nature are discussed in relation to the problems that arise in making accurate notes of analytic sessions.

  14. Advantages of later motherhood.

    2017-01-01

    In high-income countries childbearing has been increasingly postponed since the 1970s and it is crucial to understand the consequences of this demographic shift. The literature has tended to characterize later motherhood as a significant health threat for children and parents. We contribute to this debate by reviewing recent evidence suggesting that an older maternal age can also have positive effects. Literature linking the age at parenthood with the sociodemographic characteristics of the parents, with macrolevel interactions, and with subjective well-being. Comprehensive review of the existing literature. Recent studies show that there can also be advantages associated with later motherhood. First, whilst in past older mothers had low levels of education and large families, currently older mothers tend to have higher education and smaller families than their younger peers. Consequently, children born to older mothers in the past tended to have worse outcomes than children born to younger mothers, whilst the opposite is true in recent cohorts. Second, postponement of childbearing means that the child is born at a later date and in a later birth cohort, and may benefit from secular changes in the macroenvironment. Evidence shows that when the positive trends in the macroenvironment are strong they overweigh the negative effects of reproductive ageing. Third, existing studies show that happiness increases around and after childbirth among older mothers, whereas for younger mothers the effect does not exist or is short-lived. There are important sociodemographic pathways associated with postponement of childbearing which might compensate or even more than compensate for the biological disadvantages associated with reproductive ageing.

  7. Food irradiation: advantages and limitations

    International Nuclear Information System (INIS)

    Hernandes, N.K.; Vital, H. de C.; Sabaa-Srur, A.U.O.

    2003-01-01

    Food irradiation is a physical method of processing food (e.g. freezing, canning). It has been thoroughly researched over the last four decades and is recognized as a safe and wholesome method. It has the potential both of disinfesting dried food to reduce storage losses and disinfesting fruits and vegetables to meet quarantine requirements for export trade. Low doses of irradiation inhibit spoilage losses due to sprouting of root and tuber crops. Food- borne diseases due to contamination by pathogenic microorganisms and parasites of meat, poultry, fish, fishery products and spices are on the increase. Irradiation of these solid foods can decontaminate them of pathogenic organisms and thus provide safe food to the consumer. Irradiation can successfully replace the fumigation treatment of cocoa beans and coffee beans and disinfest dried fish, dates, dried fruits, etc. One of the most important advantages of food irradiation processing is that it is a coldprocess which does not significantly alter physico-chemical characters of the treated product. It can be applied to food after its final packaging. Similar to other physical processes of food processing, (e.g. canning, freezing), irradiation is a capital intensive process. Thus, adequate product volume must be made available in order to maximize the use of the facility and minimize the unit cost of treatment. Lack of harmonization of regulations among the countries which have approved irradiated foods hampers the introduction of this technique for international trade. Action at the international level has to be taken in order to remedy this situation. One of the important limitations of food irradiation processing is its slow acceptance by consumers, due inter alia to a perceived association with radioactivity. The food industry tends to be reluctant to use the technology in view of uncertainties regarding consumer acceptance of treated foods. Several market testing and consumer acceptance studies have been carried

    Katanik, Jill; McCabe, Brendan J; Brunengraber, Daniel Z; Chandramouli, Visvanathan; Nishiyama, Fumie J; Anderson, Vernon E; Previs, Stephen F

    2003-05-01

    The contribution of gluconeogenesis to glucose production can be measured by enriching body water with (2)H(2)O to approximately 0.5% (2)H and determining the ratio of (2)H that is bound to carbon-5 vs. carbon-2 of blood glucose. This labeling ratio can be measured using gas chromatography-mass spectrometry after the corresponding glucose carbons are converted to formaldehyde and then to hexamethylenetetramine (HMT). We present a technique for integrating ion chromatograms that allows one to use only 0.05% (2)H in body water (i.e., 10 times less than the current dose). This technique takes advantage of the difference in gas chromatographic retention times of naturally labeled HMT and [(2)H]HMT. We discuss the advantage(s) of using a low dose of (2)H(2)O to quantify the contribution of gluconeogenesis.

The theory is based on the influence of tacitness, context-specificity and casual ambiguity in the determinants of different types of motivation (extrinsic, normative intrinsic and hedonic intrinsic), under varying conditions of environmental dynamism. The analysis indicates the need to consider mitivational processes as a complem...

  16. Transnasal endoscopy: Technical considerations, advantages and limitations.

    Atar, Mustafa; Kadayifci, Abdurrahman

    2014-02-16

    Transnasal endoscopy (TNE) is an upper endoscopy method which is performed by the nasal route using a thin endoscope less than 6 mm in diameter. The primary goal of this method is to improve patient tolerance and convenience of the procedure. TNE can be performed without sedation and thus eliminates the risks associated with general anesthesia. In this way, TNE decreases the cost and total duration of endoscopic procedures, while maintaining the image quality of standard caliber endoscopes, providing good results for diagnostic purposes. However, the small working channel of the ultra-thin endoscope used for TNE makes it difficult to use for therapeutic procedures except in certain conditions which require a thinner endoscope. Biopsy is possible with special forceps less than 2 mm in diameter. Recently, TNE has been used for screening endoscopy in Far East Asia, including Japan. In most controlled studies, TNE was found to have better patient tolerance when compared to unsedated endoscopy. Nasal pain is the most significant symptom associated with endoscopic procedures but can be reduced with nasal pretreatment. Despite the potential advantage of TNE, it is not common in Western countries, usually due to a lack of training in the technique and a lack of awareness of its potential advantages. This paper briefly reviews the technical considerations as well as the potential advantages and limitations of TNE with ultra-thin scopes.

    1999-01-01

    Efforts by professional women in industry to encourage and mentor young women to study science and engineering and to raise the profile of women in industry are described. The case of Dr. Jane Cooley at Syncrude Research Centre is cited as an example of similar programs. Dr. Cooley provides guidance to third-year university students working on year-long internships at Syncrude. Reference is also made to the Alberta Women's Science Network (Internet address: www.awsn.com) where young women interested in careers in science and engineering can turn for advice. Female high school students unanimously complain of guidance counselors who even today discourage women from entering science and engineering programs. The general conclusion is that better guidance must start in the high schools, because missing out on the right courses in science and mathematics at that level can close career doors by the end of the twelfth grade

    Full Text Available When formal marketing thought developed in the early 1900s, dominant perspective of marketing was about taking things “to market”. After 1950 marketing thought moved to a “market to” orientation. This orientation reflects “product dominant logic”. After radical changes in information technology, knowledge asymmetry between firm and customer is decreased and customer becomes operant resource instead of a resource to be acted on. Therefore, new marketing paradigm has been emerged and main focus moved from “value in exchange” to “value in use” and customer becomes collaborative partner. Firm can only provide value proposition. New definition of marketing comprises “customer relationship”, “share holders”, and “value creation”. Apart from evolving of marketing thought, theories of competitive advantages have been also change form industry perspective to internal resource and dynamic capabilities.

    The role of environmental issues in the utility business has undergone a dramatic transition in the past few years and this new role is the basis for new definitions and new responses. Policies or products that protect the environment are now an advantage to those companies that properly capture environmental issues in their strategic planning process. This paper will focus on the underpinnings of this shift in the role of environmental protection in business and go beyond the issues of today to suggest some paradigms for the future. The current status of environmental concern is evident in the time and resources committed to environmental protection. Public officials take more proactive environmental positions; Corporations recognize environmental values in competitive equation; Citizens express willingness to pay for environmentally responsible services and products; Environmental issues tie business to the community; and Environmental planning tradeoffs are becoming more complex

    What would be the advantage of unicellular organisms becoming multicellular? For organisms that feed on organic food (heterotrophs), the most efficient way to produce energy is to metabolize the food by aerobic respiration, but the fastest way is to metabolize it by fermentation. In their Perspective, Cox and Bonner discuss a mathematical model (Pfeiffer et al.), which shows that when these two kinds of organisms (respirators and fermenters) compete for a limited food source, the respirators manage best when they are grouped in clusters rather than remaining as separate cells. In this way, multicellularity could have originated.

    Both ultrasound and CT are successfully used to guide interventional procedures throughout the body. There are advantages and disadvantages to each modality and choosing one over the other will vary from case to case. Major factors influencing choice are discussed in this paper. As a general rule CT guidance is usually required for lesions in the thorax, the adrenals, the pancreas, lymph nodes, and for percutaneous abscess drainage. The authors feel that a complimentary use of ultrasound and CT is essential to optimize success and cost-effectiveness; therefore, the interventional radiologist should be familiar with both imaging modalities

    Full Text Available The objective of this research is to analyze how organizational resources contribute to cooperatives achieving a sustainable competitive advantage. The theoretical approach of this study is the Resource Based View and VRIO model advocated by Barney and Hesterly (2007. The research was characterized as descriptive and quantitative, through data collection from secondary sources and a survey. The data collection tool was a questionnaire devised by Peacock, Sehnem and Hoffmann (2011. Data collection took place between the months of September 2014 and March 2015. The study sample was composed of a total of 215 cooperatives from across the country, divided into 13 segments. Secondary data was subjected to content analysis. The primary data was analyzed using statistical inference, namely: descriptive statistics, mean, Pearson correlation, Varimax rotation and the Kruskal-Wallis test. The main results showed that human resources are seen as important to achieving a sustainable competitive advantage. This research contributed to and enables new studies concerning the growth of cooperatives taking into account the use of internal resources.

  6. Contextual Advantage for State Discrimination

    2018-02-01

    Finding quantitative aspects of quantum phenomena which cannot be explained by any classical model has foundational importance for understanding the boundary between classical and quantum theory. It also has practical significance for identifying information processing tasks for which those phenomena provide a quantum advantage. Using the framework of generalized noncontextuality as our notion of classicality, we find one such nonclassical feature within the phenomenology of quantum minimum-error state discrimination. Namely, we identify quantitative limits on the success probability for minimum-error state discrimination in any experiment described by a noncontextual ontological model. These constraints constitute noncontextuality inequalities that are violated by quantum theory, and this violation implies a quantum advantage for state discrimination relative to noncontextual models. Furthermore, our noncontextuality inequalities are robust to noise and are operationally formulated, so that any experimental violation of the inequalities is a witness of contextuality, independently of the validity of quantum theory. Along the way, we introduce new methods for analyzing noncontextuality scenarios and demonstrate a tight connection between our minimum-error state discrimination scenario and a Bell scenario.

    Full Text Available The article examines the features of formation of competitive advantages, the depth of theoretical and methodological basis for the formation of competitive advantages at an enterprise. The author has reviewed the approaches to the formation of stable and long-term competitive advantages. The author has also overviewed the requirements which are to be met by competitive advantages of a company and the factors that affect the possibility of competitive advantages. The author develops her own approach to the definition of «competitive enterprise strategy», suggests to understand the concept as the perspective of company development, the way of achieving the goals a company sets for itself guided by its policy, using internal and external competitive advantages. The author implements the model of strategic management of enterprise development based on competitive advantage creating. The suggested model will take into account the maximum possible factors that impact on the development and implementation of strategies. Due to the model risks will also be reduced. The paper determines that the important stage of enterprise development strategic management based on competitive advantage creating is the management of changes and the management of resistance to changes caused by the influence of factors of external and internal environment.

    Full Text Available This paper took extra low permeability reservoirs in Dagang Liujianfang Oilfield as an example and analyzed different types of microscopic pore structures by SEM, casting thin sections fluorescence microscope, and so on. With adoption of rate-controlled mercury penetration, NMR, and some other advanced techniques, based on evaluation parameters, namely, throat radius, volume percentage of mobile fluid, start-up pressure gradient, and clay content, the classification and assessment method of extra low permeability reservoirs was improved and the parameter boundaries of the advantageous reservoirs were established. The physical properties of reservoirs with different depth are different. Clay mineral variation range is 7.0%, and throat radius variation range is 1.81 μm, and start pressure gradient range is 0.23 MPa/m, and movable fluid percentage change range is 17.4%. The class IV reservoirs account for 9.56%, class II reservoirs account for 12.16%, and class III reservoirs account for 78.29%. According to the comparison of different development methods, class II reservoir is most suitable for waterflooding development, and class IV reservoir is most suitable for gas injection development. Taking into account the gas injection in the upper section of the reservoir, the next section of water injection development will achieve the best results.

    Nuclear energy is controversial. But what's all about really in the controversy? It's about more than safty or electricity prices. Nuclear energy is not only a technical or political question, but also a moral, a human. The discussion enter various rational and irrational arguments, beside straightforward arguments various misleading and mendacious exist. The present publication is comprehensively dedicated to the thema of nuclear energy - its pro and contra - and considers its risks and advantages. Thereby the sources of energy, the processes in the nuclear reactor, and the risk potentials (Harrisburg, Chernobyl, Fukushima) are illustratively and reproducibly presented. Extensively the text explains the forms of the radiation, its doses, and the tolerance of it. Also to the theme waste and final disposal an explaining chapter is dedicated and the question for the exit from nuclear energy elucidated. Finally the author appoints with the question ''How considers mankind nuclear energy world-wide'' the international comparison.

    Full Text Available Issue that can already be seen and will be very clear in the future is that the central problem in the market of tube caps will not be the product or the price or promotion, but marketing channels. Therefore, the competitive advantage will most probably be built on marketing channels and not the production - as it has been so far, so, the questions of choice functioning and modification of marketing channels, as well as selection of the most appropriate members of channels will become more and more important. Accordingly, it may freely be said that the choice, i.e. the movement of marketing channels represents one of the strategic decisions which has to be made by a company management and which will subsequently very significantly influence the functioning and efficacy of not only the system of distribution, but also the entire business transactions.

  16. Advantages of Oscillatory Hydraulic Tomography

    Characterizing the subsurface is significant for most hydrogeologic studies, such as those involving site remediation and groundwater resource explo¬ration. A variety of hydraulic and geophysical methods have been developed to estimate hydraulic conductivity and specific storage. Hydraulic methods based on the analysis of conventional pumping tests allow the estimation of conductivity and storage without need for approximate petrophysical relations, which is an advantage over most geophysical methods that first estimate other properties and then infer values of hydraulic parameters. However, hydraulic methods have the disadvantage that the head-change signal decays with distance from the pumping well and thus becomes difficult to separate from noise except in close proximity to the source. Oscillatory hydraulic tomography (OHT) is an emerging technology to im¬age the subsurface. This method utilizes the idea of imposing sinusoidally varying pressure or discharge signals at several points, collecting head observations at several other points, and then processing these data in a tomographic fashion to estimate conductivity and storage coefficients. After an overview of the methodology, including a description of the most important potential advantages and challenges associated with this approach, two key promising features of the approach will be discussed. First, the signal at an observation point is orthogonal to and thus can be separated from nuisance inputs like head fluctuation from production wells, evapotranspiration, irrigation, and changes in the level of adjacent streams. Second, although the signal amplitude may be weak, one can extract the phase and amplitude of the os¬cillatory signal by collecting measurements over a longer time, thus compensating for the effect of large distance through longer sampling period.

    2016-08-01

    The purpose of this article is to review the literature and discuss the advantages of robotics in benign gynecologic surgery. Minimally invasive surgery has become the preferred route over abdominal surgery. The laparoscopic or robotic approach is recommended when vaginal surgery is not feasible. Thus far, robotic gynecologic surgery data have demonstrated feasibility, safety, and equivalent clinical outcomes in comparison with laparoscopy and better clinical outcomes compared with laparotomy. Robotics was developed to overcome challenges of laparoscopy and has led to technological advantages such as improved ergonomics, visualization with three-dimensional capabilities, dexterity and range of motion with instrument articulation, and tremor filtration. To date, applications of robotics in benign gynecology include hysterectomy, myomectomy, endometriosis surgery, sacrocolpopexy, adnexal surgery, tubal reanastomosis, and cerclage. Though further data are needed, robotics may provide additional benefits over other approaches in the obese patient population and in higher complexity cases. Challenges that arose in the earlier adoption stage such as the steep learning curve, costs, and operative times are becoming more optimized with greater experience, with implementation of robotics in high-volume centers and with improved training of surgeons and robotic teams. Robotic laparoendoscopic single-site surgery, albeit still in its infancy where technical advantages compared with laparoscopic single-site surgery are still unclear, may provide a cost-reducing option compared with multiport robotics. The cost may even approach that of laparoscopy while still conferring similar perioperative outcomes. Advances in robotic technology such as the single-site platform and telesurgery, have the potential to revolutionize the field of minimally invasive gynecologic surgery. Higher quality evidence is needed to determine the advantages and disadvantages of robotic surgery in benign

  18. Evolutionary advantages of adaptive rewarding

    Szolnoki, Attila; Perc, Matjaž

    2012-01-01

    Our well-being depends on both our personal success and the success of our society. The realization of this fact makes cooperation an essential trait. Experiments have shown that rewards can elevate our readiness to cooperate, but since giving a reward inevitably entails paying a cost for it, the emergence and stability of such behavior remains elusive. Here we show that allowing for the act of rewarding to self-organize in dependence on the success of cooperation creates several evolutionary advantages that instill new ways through which collaborative efforts are promoted. Ranging from indirect territorial battle to the spontaneous emergence and destruction of coexistence, phase diagrams and the underlying spatial patterns reveal fascinatingly rich social dynamics that explain why this costly behavior has evolved and persevered. Comparisons with adaptive punishment, however, uncover an Achilles heel of adaptive rewarding, coming from over-aggression, which in turn hinders optimal utilization of network reciprocity. This may explain why, despite its success, rewarding is not as firmly embedded into our societal organization as punishment. (paper)

  2. How Successful Is Medicare Advantage?

    Newhouse, Joseph P; McGuire, Thomas G

    2014-01-01

    Context Medicare Part C, or Medicare Advantage (MA), now almost 30 years old, has generally been viewed as a policy disappointment. Enrollment has vacillated but has never come close to the penetration of managed care plans in the commercial insurance market or in Medicaid, and because of payment policy decisions and selection, the MA program is viewed as having added to cost rather than saving funds for the Medicare program. Recent changes in Medicare policy, including improved risk adjustment, however, may have changed this picture. Methods This article summarizes findings from our group's work evaluating MA's recent performance and investigating payment options for improving its performance even more. We studied the behavior of both beneficiaries and plans, as well as the effects of Medicare policy. Findings Beneficiaries make “mistakes” in their choice of MA plan options that can be explained by behavioral economics. Few beneficiaries make an active choice after they enroll in Medicare. The high prevalence of “zero-premium” plans signals inefficiency in plan design and in the market's functioning. That is, Medicare premium policies interfere with economically efficient choices. The adverse selection problem, in which healthier, lower-cost beneficiaries tend to join MA, appears much diminished. The available measures, while limited, suggest that, on average, MA plans offer care of equal or higher quality and for less cost than traditional Medicare (TM). In counties, greater MA penetration appears to improve TM's performance. Conclusions Medicare policies regarding lock-in provisions and risk adjustment that were adopted in the mid-2000s have mitigated the adverse selection problem previously plaguing MA. On average, MA plans appear to offer higher value than TM, and positive spillovers from MA into TM imply that reimbursement should not necessarily be neutral. Policy changes in Medicare that reform the way that beneficiaries are charged for MA plan

    Recently, global nursing experts have been aggressively encouraging nurses to pursue creativity and innovation in nursing to improve nursing outcomes. Nurses' creativity plays a significant role in health and well-being. In most health systems across the world, nurses provide up to 80% of the primary health care; therefore, they are critically positioned to provide creative solutions for current and future global health challenges. The purpose of this study was to explore Iranian nurses' perceptions and experiences toward the expression of creativity in clinical settings and the outcomes of their creativity for health care organizations. A qualitative approach using content analysis was adopted. Data were collected through in-depth semistructured interviews with 14 nurses who were involved in the creative process in educational hospitals affiliated to Jahrom and Tehran Universities of Medical Sciences in Iran. Four themes emerged from the data analysis, including a) Improvement in quality of patient care, b) Improvement in nurses' quality of work, personal and social life, c) Promotion of organization, and d) Unpleasant outcomes. The findings indicated that nurses' creativity in health care organizations can lead to major changes of nursing practice, improvement of care and organizational performance. Therefore, policymakers, nurse educators, nursing and hospital managers should provide a nurturing environment that is conducive to creative thinking, giving the nurses opportunity for flexibility, creativity, support for change, and risk taking.

    2012-01-01

    Curious people seek knowledge and new experiences. In three studies, we examined whether, when, and how curiosity contributes to positive social outcomes between unacquainted strangers. Study 1 showed that curious people expect to generate closeness during intimate conversations but not during small-talk; less curious people anticipated poor outcomes in both situations. We hypothesized that curious people underestimate their ability to bond with unacquainted strangers during mundane conversations. Studies 2 and 3 showed that curious people felt close to partners during intimate and small-talk conversations; less curious people only felt close when the situation offered relationship-building exercises. Surprise at the pleasure felt during this novel, uncertain situation partially mediated the benefits linked to curiosity. We found evidence of slight asymmetry between self and partner reactions. Results could not be attributed to physical attraction or positive affect. Collectively, results suggest that positive social interactions benefits from an open and curious mindset. PMID:22092143

  10. Cognitive strategies take advantage of the cooperative potential of heterogeneous networks

    International Nuclear Information System (INIS)

    Vukov, Jeromos; Santos, Francisco C; Pacheco, Jorge M

    2012-01-01

    Understanding the emergence and maintenance of cooperation is one of the most challenging topics of our time. Evolutionary game theory offers a very flexible framework within which to address this challenge. Here we use the prisoner's dilemma game to investigate the performance of individuals who are capable of adopting reactive strategies in communities structurally organized by means of Barabási-Albert scale-free networks. We find that basic cognitive abilities, such as the capability to distinguish their partners and act according to their previous actions, enable cooperation to thrive. This result is particularly significant whenever fear is the leading social tension, as this fosters retaliation, thus enforcing and sustaining cooperation. Being able to simultaneously reward fellow cooperators and punish defectors proves instrumental in achieving cooperation and the welfare of the community. As a result, central individuals can successfully lead the community and turn defective players into cooperative ones. Finally, even when participation costs—known to be detrimental to cooperation in scale-free networks—are explicitly included, we find that basic cognitive abilities have enough potential to help cooperation to prevail.

    Full Text Available It is suggested, that the new flexible work practices are enhanced to meet the work-family demandsand therefore benefit especially women. In the article the focus is on informal flexibilitytaking place at home, for which field studies of the role of gender are rare. Against the assumptions,paid work at home is mostly informal, supplementary overtime by nature. In this article, I explorewhy employees undertake work in their private sphere during their free time and whether gendermakes a difference there. I carry out both qualitative and quantitative analyses. The qualitativedata consists of 21 interviews with white-collar employees and the quantitative data from theFinnish Quality of Work Life survey 2008 for which there are almost 4400 respondents. The methodsinclude content analysis, descriptive statistics and logistic regression analysis.According to both the qualitative and quantitative data, job characteristics play the most importantrole for all who work at home; employees with higher education, or supervisory tasks, inparallel with having an autonomous and inspiring job predict both tele- and supplemental work.Importantly, gender plays only a minor role in the puzzles of choosing when and where to work.The social relations at the workplace, including the atmosphere and the support of superiors andthe work community, are only weakly related to work at home. At the same time, supplementalwork is associated with great time pressure and involuntary overtime.

  16. Physical parameter determinations of young Ms. Taking advantage of the Virtual Observatory to compare methodologies

    Science.gov (United States)

    Bayo, A.; Rodrigo, C.; Barrado, D.; Allard, F.

    One of the very first steps astronomers working in stellar physics perform to advance in their studies, is to determine the most common/relevant physical parameters of the objects of study (effective temperature, bolometric luminosity, surface gravity, etc.). Different methodologies exist depending on the nature of the data, intrinsic properties of the objects, etc. One common approach is to compare the observational data with theoretical models passed through some simulator that will leave in the synthetic data the same imprint than the observational data carries, and see what set of parameters reproduce the observations best. Even in this case, depending on the kind of data the astronomer has, the methodology changes slightly. After parameters are published, the community tend to quote, praise and criticize them, sometimes paying little attention on whether the possible discrepancies come from the theoretical models, the data themselves or just the methodology used in the analysis. In this work we perform the simple, yet interesting, exercise of comparing the effective temperatures obtained via SED and more detailed spectral fittings (to the same grid of models), of a sample of well known and characterized young M-type objects members to different star forming regions and show how differences in temperature of up to 350 K can be expected just from the difference in methodology/data used. On the other hand we show how these differences are smaller for colder objects even when the complexity of the fit increases like for example introducing differential extinction. To perform this exercise we benefit greatly from the framework offered by the Virtual Observaotry.

    There is some general concern that economic development in developing countries will hasten global warning. In terms of reducing CO 2 emissions, fusion will have great potential as a primary energy in the late 21st century according to the results of WING model simulations based on scenario analysis, if the cost of fusion with hydrogen generation would become competitive compared with those of other substitutive energies. However, securing social acceptance is very important to maintain the fossil research funded by the government suffering from cumulative debt. (author)

    Butler, Helen; Bowes, Glenn; Drew, Sarah; Glover, Sara; Godfrey, Celia; Patton, George; Trafford, Lea; Bond, Lyndal

    2010-03-01

    Schools and school systems are increasingly asked to use evidence-based strategies to promote the health and well-being of students. The dissemination of school-based health promotion research, however, offers particular challenges to conventional approaches to dissemination. Schools and education systems are multifaceted organizations that sit within constantly shifting broader contexts. This article argues that health promotion dissemination needs to be rethought for school communities as complex systems and that this requires understanding and harnessing the dynamic ecology of the sociopolitical context. In developing this argument, the authors draw on their experience of the dissemination process of a multilevel school-based intervention in a complex educational context. Building on this experience, they argue for the need to move beyond conventional dissemination strategies to a focus on active partnerships between developers and users of school-based intervention research and offer a conceptual tool for planning dissemination.

    2014-05-01

    With the advancements in design processes down to the sub 7nm levels, the Electronic Design Automation industry appears to be coming to an end of advancements, as the size of the silicon atom becomes the limiting factor. Or is it? The commercial viability of mass-producing silicon photonics is bringing about the Optoelectronic Design Automation (OEDA) industry. With the science of photonics in its infancy, adding these circuits to ever-increasing complex electronic designs, will allow for new generations of advancements. Learning from the past 50 years of the EDA industry's mistakes and missed opportunities, the photonics industry is starting with electronic standards and extending them to become photonically aware. Adapting the use of pre-existing standards into this relatively new industry will allow for easier integration into the present infrastructure and faster time to market.

    Pasi T. Lautala, Ph.D., P.E.

    2015-06-01

    Full Text Available The United States has taken initial steps toward developing a high speed rail (HSR network, but the domestic workforce experience and institutional knowledge necessary for the planning, design, construction, and operations of HSR is underdeveloped. This paper describes and provides preliminary assessment of the High Speed Rail Learning System (HSRLS, a demonstration project that seeks to address gaps in HSR knowledge and skills in the US. The HSRLS developers designed an online education system to serve as a clearinghouse for rail-related information and content, connect teachers, trainers, and students at pre-, and postgraduate levels, and to collect demographic and professional information on groups and individuals interested in HSR. The paper explores the technology review, selection process, and content developed. Website visits and demographic information from over 4,000 unique individuals and 600 HSRLS course registrations are analyzed and assessed.

    Grzonkowski, Sławomir

    Transmission of users' profiles over insecure communication means is a crucial task of today's ecommerce applications. In addition, the users have to createmany profiles and remember many credentials. Thus they retype the same information over and over again. Each time the users type their credentials, they expose them to phishing or eavesdropping attempts.These problems could be solved by using Single Sign-on (SSO). The idea of SSO is that the users keep using the same set of credentials when visiting different websites. For web-aplications, OpenID1. is the most prominent solution that partially impelemtns SSO. However, OpenID is prone to phishing attempts and it does not preserve users' privacy [1].

  5. Taking advantage of local structure descriptors to analyze interresidue contacts in protein structures and protein complexes.

    Martin, Juliette; Regad, Leslie; Etchebest, Catherine; Camproux, Anne-Claude

    2008-11-15

    Interresidue protein contacts in proteins structures and at protein-protein interface are classically described by the amino acid types of interacting residues and the local structural context of the contact, if any, is described using secondary structures. In this study, we present an alternate analysis of interresidue contact using local structures defined by the structural alphabet introduced by Camproux et al. This structural alphabet allows to describe a 3D structure as a sequence of prototype fragments called structural letters, of 27 different types. Each residue can then be assigned to a particular local structure, even in loop regions. The analysis of interresidue contacts within protein structures defined using Voronoï tessellations reveals that pairwise contact specificity is greater in terms of structural letters than amino acids. Using a simple heuristic based on specificity score comparison, we find that 74% of the long-range contacts within protein structures are better described using structural letters than amino acid types. The investigation is extended to a set of protein-protein complexes, showing that the similar global rules apply as for intraprotein contacts, with 64% of the interprotein contacts best described by local structures. We then present an evaluation of pairing functions integrating structural letters to decoy scoring and show that some complexes could benefit from the use of structural letter-based pairing functions.

  6. Point-of-sale marketing of tobacco products: taking advantage of the socially disadvantaged?

    Science.gov (United States)

    John, Robert; Cheney, Marshall K; Azad, M Raihan

    2009-05-01

    With increasing regulation of tobacco industry marketing practices, point-of-sale advertising has become an important channel for promoting tobacco products. One hundred and ten convenience stores in Oklahoma County were surveyed for tobacco-related advertising. There were significantly more point-of-sale tobacco advertisements in low-income and minority neighborhoods than in better educated, higher-income, predominantly White neighborhoods. Storeowners or managers were also interviewed to determine who has decision-making power regarding store signage and placement, and to elicit perceptions of industry tactics. Contracts with tobacco companies leave storeowners with little or no control over promotion of tobacco products within their store, and many are unaware of the implications of the tobacco industry point-of-sale practices. Local ordinances that regulated outdoor signage reduced outdoor tobacco advertisements, as well as tobacco signage and promotions within the store. Policy change, rather than education targeting storeowners, is recommended as the most effective strategy for reducing point-of-sale tobacco advertising.

    Clinical data warehouses have accelerated clinical research, but even with available open source tools, there is a high barrier to entry due to the complexity of normalizing and importing data. The Office of the National Coordinator for Health Information Technology's Meaningful Use Incentive Program now requires that electronic health record systems produce standardized consolidated clinical document architecture (C-CDA) documents. Here, we leverage this data source to create a low volume standards based import pipeline for the Informatics for Integrating Biology and the Bedside (i2b2) clinical research platform. We validate this approach by creating a small repository at Partners Healthcare automatically from C-CDA documents. We designed an i2b2 extension to import C-CDAs into i2b2. It is extensible to other sites with variances in C-CDA format without requiring custom code. We also designed new ontology structures for querying the imported data. We implemented our methodology at Partners Healthcare, where we developed an adapter to retrieve C-CDAs from Enterprise Services. Our current implementation supports demographics, encounters, problems, and medications. We imported approximately 17 000 clinical observations on 145 patients into i2b2 in about 24 min. We were able to perform i2b2 cohort finding queries and view patient information through SMART apps on the imported data. This low volume import approach can serve small practices with local access to C-CDAs and will allow patient registries to import patient supplied C-CDAs. These components will soon be available open source on the i2b2 wiki. Our approach will lower barriers to entry in implementing i2b2 where informatics expertise or data access are limited. © The Author 2014.

    NASA is in the process of modernizing its communications infrastructure to accompany the development of a Crew Exploration Vehicle (CEV) to replace the shuttle. With this effort comes the opportunity to infuse more advanced coded modulation techniques, including low-density parity-check (LDPC) codes that offer greater coding gains than the current capability. However, in order to take full advantage of these codes, the ground segment receiver synchronization loops must be able to operate at a lower signal-to-noise ratio (SNR) than supported by equipment currently in use.

  20. Using integration technology as a strategic advantage.

    Science.gov (United States)

    Fry, P A

    1993-08-01

    The underlying premise of the Managed Competition Act previously cited is that through managed competition providers will be forced to lower care costs while increasing the level of positive care outcomes. Because it may also be that tomorrow's hospitals will find a severe rationing of technology, what can they do to prepare? Most of the systems in place today already have built within them all the necessary potential to address this premise and technology requirement with no change, no conversion, no expense for new equipment and software, and no disruption in day-to-day operations, just a little re-engineering. Today, however, these systems are similar to a 20-mule team pulling in different directions: all the power is there, but the wagon remains motionless and totally unable to reach its objective. It takes a skilled wagonmaster to bring them together, to make the mules work as a cohesive unit, to make the power of 20 mules greater than the sum of 20 mules. So it is and will be for the hospital of tomorrow. System integration is no longer a question of whether but of when. Those hospitals that use it today as a strategic advantage will be in a better position tomorrow to use it as a competitive strategic advantage in an environment that will reward low cost and high positive care outcomes and will penalize those that cannot compete. The technology is already here and economically within reach of nearly every hospital, just waiting to be used. The question that must nag all of us who want to make the health care system of America better is, Why not make the when now? Rich Helppie, president of Superior Consultant Company, summarized the solution well: The old ways will not give way to the new overnight. The re-engineering process in healthcare must evolve. Compared to the last 20 years, however, such evolution may appear to be a massive, forthright, complete, comprehensive, drastic and rapid revolution. Survival is the name of the game, and for healthcare

    2007-03-01

    Whether you're in a traditional smokestack industry or a "clean" business like investment banking, your company will increasingly feel the effects of climate change. Even people skeptical about global warming's dangers are recognizing that, simply because so many others are concerned, the phenomenon has wide-ranging implications. Investors already are discounting share prices of companies poorly positioned to compete in a warming world. Many businesses face higher raw material and energy costs as more and more governments enact policies placing a cost on emissions. Consumers are taking into account a company's environmental record when making purchasing decisions. There's also a burgeoning market in greenhouse gas emission allowances (the carbon market), with annual trading in these assets valued at tens of billions of dollars. Companies that manage and mitigate their exposure to the risks associated with climate change while seeking new opportunities for profit will generate a competitive advantage over rivals in a carbon-constrained future. This article offers a systematic approach to mapping and responding to climate change risks. According to Jonathan Lash and Fred Wellington of the World Resources Institute, an environmental think tank, the risks can be divided into six categories: regulatory (policies such as new emissions standards), products and technology (the development and marketing of climate-friendly products and services), litigation (lawsuits alleging environmental harm), reputational (how a company's environmental policies affect its brand), supply chain (potentially higher raw material and energy costs), and physical (such as an increase in the incidence of hurricanes). The authors propose a four-step process for responding to climate change risk: Quantify your company's carbon footprint; identify the risks and opportunities you face; adapt your business in response; and do it better than your competitors.

    2014-01-01

    Full Text Available The article considers evolution of development of the paradigm of ensuring competitive advantages of an enterprise. Foreign and domestic scientists focus on individual directions of development of competitive advantages and pay insufficient attention to new management concepts – development of the information society, knowledge economy and dynamism of integration processes. The goal of the study is formation of the modern paradigm of ensuring competitive advantages of an enterprise with consideration of tendencies of development of the knowledge economy, information society and integration processes. Enterprise competitiveness is a synergetic characteristic, which reflects enterprise capability of dynamic response to changes of the market situation with the aim of keeping predominance over other economic subjects. Management of the future, on the basis of the management 2.0 concept, should take into account interests not only of top management and shareholders but also employees, local communities and territories and meet requirements of the society in general, individual groups of consumers and tendencies of development of managerial and information technologies. The paradigm of the modern theory of ensuring competitive advantages should include models of keeping competitive advantages in the existing markets and models of development of future markets; strategy of development of enterprise competitiveness, human capital development and efficient enterprise management.

  11. Perspective Taking in Workplaces

    Full Text Available Workplaces are often described as places in which individuals are motivated by their self-interests and in which negative events like time pressure, anxiety, conflict with co-workers, miscomprehensions, difficulties in solving problems, not-transmitted or not-exchanged information that lead to mistakes, and in some cases to injuries, stress or control, are part of everyday life (Dormann & Zapf, 2002; Schabracq, Winnubst and Cooper, 2003. Such situations are often the result of the limited comprehension of needs, skills, or information available to colleagues, supervisors, subordinates, clients or providers. However, workplaces are also places in which employees take care of clients, support colleagues and subordinates (Rhoades & Eisenberger, 2002, are enthusiastic about their job (Bakker et al., 2008, are motivated by leaders that encourage employees to transcend their own self-interests for the good of the group or the organization and provide them with the confidence to perform beyond expectations (Bass, 1997. Thus positive relationships at work are becoming a new interdisciplinary domain of inquiry (Dutton & Ragins, 2006. Within this positive relationships framework, in this paper we focus on a positive component of workplaces, and particularly on an individual cognitive and emotional process that has an important role in the workplace because it facilitates interpersonal relations and communications: it is the perspective taking process. In order to describe perspective taking, we will refer to some empirical studies and particularly to the review published by Parker, Atkins and Axtell in 2008 on the International Review of Industrial and Organizational Psychology.

  12. Sampling vs. taking some - 59349

    Francois-Bongarcon, D.

    2012-01-01

    Collecting a sample is a delicate task that is Not naively equivalent to simply 'taking some of the material'. The question examined is: 'What is it exactly?' The problem of sampling in general, and for nuclear decontamination in particular, is properly defined. A theory is presented (Gy's Theory of Sampling, a.k.a. TOS) that brings all the answers and allows us to put them to work. The author draws form his lifelong experience in research, teaching and practical applications in this domain to emphasize the critical odds (i.e. risks) of not taking sampling explicitly into account when assessing grades and concentrations. The evolution of the acceptance of this theory in the nuclear industry is finally illustrated, and a hopeful glimpse into the future concludes the presentation. Equally interesting, however, besides what has already been achieved at the CEA along these years, is the realization of what could not be done with TOS, and therefore had to be treated in some other ways - e.g. using mapping tools (geostatistical). It is one the great side-advantages of using a consistent theory that it warns you, before it is too late, that what you are trying to do will not work: TOS, indeed, much like its Geo-statistics sister, besides preventing many a disaster, can provide pragmatic lessons in scientific humility that are best not being left ignored. In conclusion, there are great tools out there, such as TOS, that are well worth investing into, and that our community should be much more attuned to. (author)

    This study is divided into three parts. The first, devoted to the use of radiations in food production, deals especially with artificial mutagenesis, selectors taking advantage of altered hereditary features in plants from irradiated seed; sterilization of animals to eliminate harmful insects (male sterilization technique); the lethal power of radiations used for the production of animal vaccins, attenuated by irradiation, against organisms which infest or degrade food products. Part two shows that radioactive atoms used as tracers to reveal migrations and chemical transformations of products such as fertilizers and pesticides can speed up all kinds of agronomical research. Their possibilities in research on animal feeding and to detect poisonous substances in foodstuffs are also mentioned. The last part is devoted to the use of nuclear techniques in irrigation and more precisely in the study of underground water flows soil moisture and lastly the future of nuclear desalination [fr

  14. Wind power takes over

    International Nuclear Information System (INIS)

    2002-01-01

    All over the industrialized world concentrated efforts are being made to make wind turbines cover some of the energy demand in the coming years. There is still a long way to go, however, towards a 'green revolution' as far as energy is concerned, for it is quite futile to use wind power for electric heating. The article deals with some of the advantages and disadvantages of developing wind power. In Norway, for instance, environmentalists fear that wind power plants along the coast may have serious consequences for the stocks of white-tailed eagle and golden eagle. An other factor that delays the large-scale application of wind power in Norway is the low price of electricity. Some experts, however, maintain that wind power may already compete with new hydroelectric power of intermediate cost. The investment costs are expected to go down with one third by 2020, when wind power may be the most competitive energy source to utilize

  19. Mechanistic Basis of Cocrystal Dissolution Advantage.

    Cao, Fengjuan; Amidon, Gordon L; Rodríguez-Hornedo, Naír; Amidon, Gregory E

    2018-01-01

    Current interest in cocrystal development resides in the advantages that the cocrystal may have in solubility and dissolution compared with the parent drug. This work provides a mechanistic analysis and comparison of the dissolution behavior of carbamazepine (CBZ) and its 2 cocrystals, carbamazepine-saccharin (CBZ-SAC) and carbamazepine-salicylic acid (CBZ-SLC) under the influence of pH and micellar solubilization. A simple mathematical equation is derived based on the mass transport analyses to describe the dissolution advantage of cocrystals. The dissolution advantage is the ratio of the cocrystal flux to drug flux and is defined as the solubility advantage (cocrystal to drug solubility ratio) times the diffusivity advantage (cocrystal to drug diffusivity ratio). In this work, the effective diffusivity of CBZ in the presence of surfactant was determined to be different and less than those of the cocrystals. The higher effective diffusivity of drug from the dissolved cocrystals, the diffusivity advantage, can impart a dissolution advantage to cocrystals with lower solubility than the parent drug while still maintaining thermodynamic stability. Dissolution conditions where cocrystals can display both thermodynamic stability and a dissolution advantage can be obtained from the mass transport models, and this information is useful for both cocrystal selection and formulation development.

    1998-01-01

    An overview of Western Canada Sedimentary Basin (WCSB) natural gas supply, past, present and future, was presented. Reserves are considered as being more than adequate to meet supply requirements. In the long term, it is expected that there will be sufficient gas to fill all existing and currently planned pipelines serving the WCSB. Nevertheless, it does not pay to take anything for granted. One of the challenges facing the natural gas industry in an integrated North American market is to maintain a balance between deliverability and take-away capacity. Competition between fuels is also a factor that complicates matters. Measures taken by TransCanada Pipelines to prepare for the expected heightened competition were reviewed. Chief among them is the recent TransCanada/Nova merger which is expected to increase efficiency, decrease costs, provide a solid platform for continued growth, create customer-driven energy solutions and enable the new entity to successfully compete in an integrated North American market. The accord reached between CAPP, NOVA, SEPAC and TransCanada Pipelines and the status of the new Alberta tolls are further examples of measures taken by TransCanada Pipelines to prepare for all contingencies by leaving nothing to chance

The competitive advantage is volatile, difficult to obtain and more difficult to maintain and strengthened with consumers who through their individual choices polarization confirms the recognition performance and award competitive advantages, thus causing the competitive ranking of companies present in a particular market. The competitive advantage lies in the focus of the performance of companies in competitive markets and innovation is a source for obtaining and consolidating it. Companies will need to demonstrate the capacity to adapt to changes in the business environment so as to maintain the helded positions. This paper treats this aspect behavior that companies should adopt to get on the account of innovation a sustainable competitive advantage. I started of the work in the elaboration from the theory of developed by Michael Porter in his book "Competitive Advantage: Creating and Sustaining Superior Performance" we applied methods listed thus trying to point out possible ways of creating competitive advantage by companies. We have presented the sources of competitive advantage and the factors on which depends its creation. Walking theoretical research revealed how lack of competitive advantage leads to a lack of competitiveness of companies and the benefits that arise with the creation of this type of asset. Among the most important benefits is to increase performances.

    1978-02-01

    The art of history taking involves the ability to recognize the interrelationship between the details of the medical history and the patient's personal history. For the oral surgeon, this provides important insights into how the patient has reacted to illness in the past as well as how he is most likely to react to current treatment. Specific problems have been reviewed as well as suggested interview techniques to guide the oral surgeon in his management of his patient's reactions. No one expects the doctor to be an iconoclast. He cannot be all things to all patients. He should recognize a problem, acknowledge it as a problem, and be flexible enough to deal with it or refer the patient to someone who can. This kind of understanding will enable the oral surgeon to fulfill his role with appreciation from his patients and an inner sense of professional and personal achievement.

    Significant increase in violent crimes in recent years forced Icelandic men to take action against violence. Television was seen as a major contributory factor in increasing violence. Surveys indicate that 10-15 years after television broadcasting commences in a particular society, the incidence of crime can be expected to double. While the majority of the individuals arrested for violent crimes are men, being male does not necessarily mean being violent. The Men's Committee of the Icelandic Equal Rights Council initiated a week-long information and education campaign under the theme "Men Against Violence". This campaign involved several events including an art exhibit, speeches on violence in families, treatment sought by those who are likely to resort to violence, booklet distribution among students in secondary schools, and a mass media campaign to raise public awareness on this pressing problem.

  8. Exploring the sequential lineup advantage using WITNESS.

    Science.gov (United States)

    Goodsell, Charles A; Gronlund, Scott D; Carlson, Curt A

    2010-12-01

    Advocates claim that the sequential lineup is an improvement over simultaneous lineup procedures, but no formal (quantitatively specified) explanation exists for why it is better. The computational model WITNESS (Clark, Appl Cogn Psychol 17:629-654, 2003) was used to develop theoretical explanations for the sequential lineup advantage. In its current form, WITNESS produced a sequential advantage only by pairing conservative sequential choosing with liberal simultaneous choosing. However, this combination failed to approximate four extant experiments that exhibited large sequential advantages. Two of these experiments became the focus of our efforts because the data were uncontaminated by likely suspect position effects. Decision-based and memory-based modifications to WITNESS approximated the data and produced a sequential advantage. The next step is to evaluate the proposed explanations and modify public policy recommendations accordingly.

  12. The advantages of hydraulic packing extraction

    International Nuclear Information System (INIS)

    Baker, R.S.

    1991-01-01

    Today's competitive environment, coupled with industry's desire to improve the efficiency of plant maintenance and operations, has management continually seeking ways to save time, money, and, at nuclear plants, radiation exposure. One area where a tremendous improvement in efficiency can be realized is valve packing removal. For example, industry experience indicates that up to 70% of the time it takes to repack a valve can be spent just removing the old packing. In some case, the bonnets of small valves are removed to facilitate packing removal and prevent stem and stuffing box damage that can occur when using packing removal picks. In other cases, small valves are simply removed and discarded because it costs less to replace the valves than to remove the packing using conventional methods. Hydraulic packing extraction greatly reduces packing removal time and will not damage the stem nor stuffing box, thus eliminating the need for bonnet removal or valve replacement. This paper will review some of the more common problems associated with manual packing extraction techniques. It will explain how hydraulic packing extraction eliminates or greatly reduces the impact of each of the problem areas. A discussion will be provided of some actual industry operating experiences related to success stories using hydraulic packing extraction. The paper will also briefly describe the operating parameters associated with hydraulic packing extraction tools. Throughout the paper, actual operating experiences from the nuclear power, fossil power, petrochemical, and refinery industries will be used to support the conclusion that hydraulic packing extraction is an alternative that can save time, money, and exposure

  1. Medicaid: taking stock.

    Science.gov (United States)

    Davidson, S M

    1993-01-01

    In the last few years, Medicaid has attracted more than casual attention, one reflection of which is the fact that JHPPL has published five papers on the program in its last few issues. This paper, a sixth, takes a broader view of the program than is typically the case. After a critique of the five recent articles, I discuss several questions raised by them and reach the following conclusions: First, the states do not invest enough in producing program data suitable for policy analysis and research. One lesson: Better data and analysis can help the states to avoid expensive mistakes. Second, those policy analyses that have been offered fail to give sufficient attention to the political dimension of policy. That is one reason why policy choices produce unexpected effects. Third, since Medicaid is a relatively small player in the vast medical care market, incentives adopted by Medicaid officials throughout the country rarely have the desired effects. Finally, as long as Medicaid remains the principal mechanism to provide access to health care for the poor, it must be made as efficient and effective as possible. Yet, for both political and economic reasons, Medicaid can never be what its original planners had hoped, the vehicle for providing the poor with reliable access to mainstream medical care.

    1980-10-07

    The invention refers to the equipment for testing water-bearing levels in loose rocks. Its purpose is to simultaneously remove with the rock sample a separate fluid sample from the assigned interval. The sample-taking apparatus contains a core lifter which can be submerged into the casting string with housing and front endpiece in the form of a rod with a piston which covers the cavity of the core lifter, as well as mechanism for fixing and moving the endpiece within the core lifter cavity. The device differs from the known similar devices because the upper part of the housing of the core lifter is equipped with a filter and mobile casting which covers the filter. In this case the casing is connected to the endpiece rod and the endpiece is installed with the possibility of movement which is limited with fixing in the upper position and in the extreme upper position it divides the core lifter cavity into two parts, filter settling tank and core-receiving cavity.

    2018-01-21

    To evaluate the clinical advantages of single-port laparoscopic hepatectomy (SPLH) compare to multi-port laparoscopic hepatectomy (MPLH). We retrospectively reviewed the medical records of 246 patients who underwent laparoscopic liver resection between January 2008 and December 2015 at our hospital. We divided the surgical technique into two groups; SPLH and MPLH. We performed laparoscopic liver resection for both benign and malignant disease. Major hepatectomy such as right and left hepatectomy was also done with sufficient disease-free margin. The operative time, the volume of blood loss, transfusion rate, and the conversion rate to MPLH or open surgery was evaluated. The post-operative parameters included the meal start date after operation, the number of postoperative days spent in the hospital, and surgical complications was also evaluated. Of the 246 patients, 155 patients underwent SPLH and 91 patients underwent MPLH. Conversion rate was 22.6% in SPLH and 19.8% in MPLH ( P = 0.358). We performed major hepatectomy, which was defined as resection of more than 2 sections, in 13.5% of patients in the SPLH group and in 13.3% of patients in the MPLH group ( P = 0.962). Mean operative time was 136.9 ± 89.2 min in the SPLH group and 231.2 ± 149.7 min in the MPLH group ( P started earlier in the SPLH group (1.06 ± 0.27 d after operation) than in the MPLH group (1.63 ± 1.27 d) ( P < 0.001). The mean hospital stay after operation was non-significantly shorter in the SPLH group than in the MPLH group (7.82 ± 2.79 d vs 7.97 ± 3.69 d, P = 0.744). The complication rate was not significantly different ( P = 0.397) and there was no major perioperative complication or mortality case in both groups. Single-port laparoscopic liver surgery seems to be a feasible approach for various kinds of liver diseases.

    Spread spectrum communication techniques have been recognized as a viable method to gain an advantage in interference environments. Many military-oriented systems have been initiated, and some civil systems have been attempted. Spread spectrum allows the ability to hide the signal of interest below or in the noise floor, so as not to be detected. A spread spectrum system is one in which the transmitted signal is spread over a wide frequency band, much wider, in fact, than the minimum bandwidth required to transmit the information being sent. We at Army Research Lab (ARL) are proposing using the same technique on the Internet with port hopping. The information would be transmitted in data packets over multiple ports. The port used would vary per packet or per session basis. This port hopping gives you and the recipients the ability to take datagram's and spread them out over a multitude of ports. This will hide information among the Internet noise. This will allow trusted communications between the transmitter and receiver because of the port coding sequence. There are 64K possible ports to span datagram. Jamming of transmission would be limiting the ability of the sniffer/listener. Also, the listener will find it difficult to use a man in the middle attach, since the data will be spread over multiple ports and only the receiver and transmitter will know the specific port sequencing for the datagram.

    predictive monitoring. The testing in this strategy is part of an effort to ensure that the desired function is not only available today, but will be available tomorrow as well. This paper considers the application of a streamlined form of RCM to the Emergency Core Cooling (ECC) and Standby Generator (SG) Systems of a CANDU plant. Recently completed studies provide useful insight into the important value added of the systematic assessment approach (using RCM techniques) for these standby safety systems. In the case of RCM analysis performed on the Emergency Core Cooling (ECC) System of Point Lepreau Nuclear Power Generating Station (PLGS), it was found that 60% of the current maintenance tasks are testing (functional, stroke, logic, and annunciation tests). Similarly, the SGs have 50% of the maintenance tasks associated with testing. The paper considers how the results of the RCM analysis demonstrate that the analysis can be used to assist in the optimization of the testing program dictated by reliability while also taking better advantage of the testing through condition monitoring and predictive maintenance techniques. Further, the results illustrate the importance of identifying and linking the different plant activities within a well integrated plant culture. (author)

    Full Text Available The paper analyzes the cost of financing through financial and operational leasing due to the deductibility of depreciation and interest. The shareholders of any company aim to obtain profit and to increase their ownership equity. In order for this to happen, the company must have profit, for which a corporate tax must be paid. A good management translates into choosing the most advantageous means of financing, which will lead to paying a lower corporate tax. Leasing and the non-taxation of reinvested profits are two means through which companies can obtain significant fiscal advantages, by increasing the deductible expenses, or by paying lower taxes.

    2004-01-01

    To be consistently profitable, a construction company must complete projects in scope, on schedule, and on budget. At the same time, the nature of the often high-risk work performed by construction companies can result in high accident rates. Clients and other stakeholders are placing increasing pressure on companies to decrease those accident rates. Clients routinely demand copies of safety plans and evidence of past results at the "pre-qualification" or "request for proposal" stages of the procurement process. Are high accident rates and the associated costs just a part of business? Companies that deliver on scope, schedule, and budget have a competitive advantage. Is it possible for projects with low accident rates to use it as a competitive advantage? Is the value added by safety just a temporary or parity issue, or does a successful safety program offer significant advantage to the company and the client? This article concludes that in the case of a high-risk industry, such as the construction industry, an organization with a successful safety program can promote safety performance as a sustainable competitive advantage. It is a choice the company can make.

  15. The half-truth of first-mover advantage.

    Science.gov (United States)

    Suarez, Fernando; Lanzolla, Gianvito

    2005-04-01

    Many executives take for granted that the first company in a new product category gets an unbeatable head start and reaps long-lasting benefits. But that doesn't always happen. The authors of this article discovered that much depends on the pace at which the category's technology is changing and the speed at which the market is evolving. By analyzing these two factors, companies can improve their odds of succeeding as first movers with the resources they possess. Gradual evolution in both the technology and the market provides a first mover with the best conditions for creating a dominant position that is long lasting (Hoover in the vacuum cleaner industry is a good example). In such calm waters, a company can defend its advantages even without exceptional skills or extensive financial resources. When the market is changing rapidly and the product isn't, a first entrant with extensive resources can obtain a long-lasting advantage (as Sony did with its Walkman personal stereo); a company with only limited resources probably must settle for a short-term benefit. When the market is static but the product is changing constantly, first-mover advantages of either kind--durable or short-lived--are unlikely. Only companies with very deep pockets can survive (think of Sony and the digital cameras it pioneered). Rapid churn in both the technology and the market creates the worst conditions. But if companies have an acute sense of when to exit-as Netscape demonstrated when it agreed to be acquired by AOL-a worthwhile short-term gain is possible. Before venturing into a newly forming market, you need to analyze the environment, assess your resources, then determine which type offirst-mover advantage is most achievable. Once you've gone into the water, you have no choice but to swim.

Este artículo examina la ventaja comparativa revelada de las exportaciones de servicios de los países del CARIFORUM. El análisis muestra que la mayoría de los países del CARIFORUM han puesto de manifiesto las ventajas comparativas en el turismo, pero también hay casos de ventaja comparativa revelada en otros servicios como transporte, seguros y servicios empresariales, servicios personales, culturales y recreativos. Los resultados sugieren que existe un potencial de CARIFORUM para diversificar las exportaciones de servicios con el fin de pro-mover el crecimiento económico y reducir la vulnerabilidad. Sin embargo, en la medida en que los países del CARIFORUM pueden tomar ventaja de las oportunidades existentes de acceso al Mercado de los servicios depende de su capacidad de mejorar la capacidad de oferta de servicios y promover la competitividad de los servicios. English: Despite the importance of services ex-ports to CARIFORUM countries there is limited research on the competitiveness of such exports. This article examines the revealed comparative advantage of services exports in CARIFORUM countries. The analysis shows that most CARIFORUM countries have revealed comparative advantage in tourism but there are also cases of revealed comparative advantage in other services including transport, insurance, business services and personal, cultural and recreational services. The results suggest that there is potential for CARIFORUM to diversify exports of services in order to promote economic growth and reduce vulnerability. However, the extent to which CARIFORUM countries can take advantage of existing market access opportunities for services depends on their ability to improve the capacity to supply services and to promote the competitiveness of services.

    Macfarlane, Michael Alex

    2014-01-01

    In the current period of health industry reform, accountable care organizations (ACOs) have emerged as a new model for the delivery of high-quality and cost-effective healthcare. However, few ACOs operate in direct competition with one another, and the accountable care business model has yet to present a means of continually developing new marginal value for patients and network partners. With value-based purchasing and patient consumerism strengthening as market forces, ACOs must build organizational sustainability and competitive advantage to meet the value demands set by customers and competitors. This essay proposes a strategy, adapted from the disciplines of agile software development and Lean product development, through which ACOs can engage internal and external customers in the development of new products that will provide sustainability and competitive advantage to the organization by decreasing waste in development, promoting specialized knowledge, and closely targeting customer value.

Throughout the methodology, fuzzy logic is the basis for translating linguistic judgments required for the relationships and correlation matrix to numerical values. Moreover, final ranking of lean enablers is represented through area ranking method and taking into account various techniques of decision makers’ risk. Finally, a case study in automotive industry is introduced to demonstrate the implementation of the proposed methodology.

  3. Huffman-based code compression techniques for embedded processors

    KAUST Repository

    Bonny, Mohamed Talal

    2010-09-01

    The size of embedded software is increasing at a rapid pace. It is often challenging and time consuming to fit an amount of required software functionality within a given hardware resource budget. Code compression is a means to alleviate the problem by providing substantial savings in terms of code size. In this article we introduce a novel and efficient hardware-supported compression technique that is based on Huffman Coding. Our technique reduces the size of the generated decoding table, which takes a large portion of the memory. It combines our previous techniques, Instruction Splitting Technique and Instruction Re-encoding Technique into new one called Combined Compression Technique to improve the final compression ratio by taking advantage of both previous techniques. The instruction Splitting Technique is instruction set architecture (ISA)-independent. It splits the instructions into portions of varying size (called patterns) before Huffman coding is applied. This technique improves the final compression ratio by more than 20% compared to other known schemes based on Huffman Coding. The average compression ratios achieved using this technique are 48% and 50% for ARM and MIPS, respectively. The Instruction Re-encoding Technique is ISA-dependent. It investigates the benefits of reencoding unused bits (we call them reencodable bits) in the instruction format for a specific application to improve the compression ratio. Reencoding those bits can reduce the size of decoding tables by up to 40%. Using this technique, we improve the final compression ratios in comparison to the first technique to 46% and 45% for ARM and MIPS, respectively (including all overhead that incurs). The Combined Compression Technique improves the compression ratio to 45% and 42% for ARM and MIPS, respectively. In our compression technique, we have conducted evaluations using a representative set of applications and we have applied each technique to two major embedded processor architectures

    Three studies conducted among fifth and sixth graders examined how school contexts disrupt the achievement of working-class students by staging unfair comparison with their advantaged middle-class peers. In regular classrooms, differences in performance among students are usually showcased in a way that does not acknowledge the advantage (i.e., higher cultural capital) experienced by middle-class students, whose upbringing affords them more familiarity with the academic culture than their working-class peers have. Results of Study 1 revealed that rendering differences in performance visible in the classroom by having students raise their hands was enough to undermine the achievement of working-class students. In Studies 2 and 3, we manipulated students' familiarity with an arbitrary standard as a proxy for social class. Our results suggest that classroom settings that make differences in performance visible undermine the achievement of the students who are less familiar with academic culture. In Study 3, we showed that being aware of the advantage in familiarity with a task restores the performance of the students who have less familiarity with the task.

  18. Explaining Asian Americans’ academic advantage over whites

    Hsin, Amy; Xie, Yu

    2014-01-01

    The superior academic achievement of Asian Americans is a well-documented phenomenon that lacks a widely accepted explanation. Asian Americans’ advantage in this respect has been attributed to three groups of factors: (i) socio-demographic characteristics, (ii) cognitive ability, and (iii) academic effort as measured by characteristics such as attentiveness and work ethic. We combine data from two nationally representative cohort longitudinal surveys to compare Asian-American and white students in their educational trajectories from kindergarten through high school. We find that the Asian-American educational advantage is attributable mainly to Asian students exerting greater academic effort and not to advantages in tested cognitive abilities or socio-demographics. We test explanations for the Asian–white gap in academic effort and find that the gap can be further attributed to (i) cultural differences in beliefs regarding the connection between effort and achievement and (ii) immigration status. Finally, we highlight the potential psychological and social costs associated with Asian-American achievement success. PMID:24799702

    The main promise of quantum computing is to efficiently solve certain problems that are prohibitively expensive for a classical computer. Most problems with a proven quantum advantage involve the repeated use of a black box, or oracle, whose structure encodes the solution. One measure of the algorithmic performance is the query complexity, i.e., the scaling of the number of oracle calls needed to find the solution with a given probability. Few-qubit demonstrations of quantum algorithms, such as Deutsch-Jozsa and Grover, have been implemented across diverse physical systems such as nuclear magnetic resonance, trapped ions, optical systems, and superconducting circuits. However, at the small scale, these problems can already be solved classically with a few oracle queries, limiting the obtained advantage. Here we solve an oracle-based problem, known as learning parity with noise, on a five-qubit superconducting processor. Executing classical and quantum algorithms using the same oracle, we observe a large gap in query count in favor of quantum processing. We find that this gap grows by orders of magnitude as a function of the error rates and the problem size. This result demonstrates that, while complex fault-tolerant architectures will be required for universal quantum computing, a significant quantum advantage already emerges in existing noisy systems.

    This article shows medical groups how they can employ new financial management and information technology techniques to safeguard their revenue and income streams. These managerial techniques stem from the application of the medical group revenue function, which is defined herein. This article also describes how the medical group revenue function can be used to create value by employing a database and a decision support system. Finally, the article describes how the decision support system can be used to create competitive advantage. Through the wise use of internally generated information, medical groups can negotiate better contract terms, improve their operations, cut their costs, embark on capital investment programs and improve market share. As medical groups gain market power by improving in these areas, they will be more attractive to potential strategic allies, payers and investment bankers.

  2. Specialized financing techniques

    International Nuclear Information System (INIS)

    Shepherd, J.

    1992-01-01

    Specific financing techniques applicable to wind energy projects in Canada are discussed. A limited partnership is the classic Canadian approach to tax-advantaged financing. For a typical wind project, the limited partners would get an internal rate of return of around 8% over 20 years as well as income tax deductions on Class 34 investments. This rate can be improved if the investors borrow some of the money; they get tax-free cash flow while having deductible loan interest, raising their rate of return after taxes to ca 9-10%. Special situation investors can get to take all of the Class 34 deduction right away, raising their return up to the 12% range. These investors include principal business corporations (such as utilities or oil companies), or companies who have sold their business. A second type of financing structure is related to inflation-indexed debt. The loan is structured like a mortgage, with the annual payments indexed to inflation but nevertheless low enough to provide an early positive cash flow from the project. Other possible financing structures are the immigrant investor fund and the provincial incentive corporations

    The data of Gunung Ledang region of Malaysia acquired through LANDSAT are considered to map certain hydrogeolocial features. To map these significant features, image-processing tools such as contrast enhancement, edge detection techniques are employed. The advantages of these techniques over the other methods are evaluated from the point of their validity in properly isolating features of hydrogeolocial interest are discussed. As these techniques take the advantage of spectral aspects of the images, these techniques have several limitations to meet the objectives. To discuss these limitations, a morphological transformation, which generally considers the structural aspects rather than spectral aspects from the image, are applied to provide comparisons between the results derived from spectral based and the structural based filtering techniques.

    2012-01-01

    The hybrid imaging methods- Single Photon Emission Tomography-Computer Tomography / SPECT-CT / and Positron Emission Tomography-Computer Tomography / PET-CT/ allow receiving of combined image of two different techniques. In such a way it is possible to superimpose detailed anatomical image of the multislice spiral computer tomography with specific and sensitive molecular images of the SPECT and PET in a single study, allowing utilization of the full possibilities of the both techniques. They have advantages and disadvantages, which basically stem from the differences in the used radiopharmaceuticals and their physical properties. In PET-CT-positron emitters are applied, most often 18F and 11C, while-in SPECT-CT - single photon emitters, most often 99mTc and 131I. A disadvantage of PET is a high cost, which is produced in cyclotron and its logistics is complicated. The great advantage of PET is its better spatial resolution, compared to SPECT, because of the possibility to for simultaneous detection of pared photons and better registration. These techniques, especially PET-CT are nowadays the most increasing imaging methods in the world in making diagnosis, staging and following the effect of treatment in patients with oncological, neurological, cardiological, orthopedic diseases and infections. Recently, they are applied for the purposes of radiotherapy planning on the basis of the metabolically active tumour. As a final result, compared to the conventional techniques- roentgenography, computer tomography and magnetic resonance imaging, it is possible in many cases to make an early and more precise diagnosis and to safe time for the patient for adequate treatment. As a conclusion it is clear, that the hybrid imaging has future and its application will increase in future

    Full Text Available Recently, laparoscopic and afterwards robotic techniques have constituted most of urologic surgery procedures. Open surgery may give place to robotic surgery due to possible widespread use of robots in the future. Studies, that compare these two techniques are usually designed about radical prostatectomy, since it is the most common operation performed by using these techniques. In literature,robotic surgery seems more advantageous than other techniques but the most important disadvantage of this technique is cost-effective problems. In present review,history of open, laparoscopic and robotic surgery, and comparison of advantages, disadvantages and cost of these techniques have been discussed with literature.

    Cadmium zinc telluride (CdZnTe, or CZT) is a room-temperature semiconductor radiation detector that has been developed in recent years for a variety of applications. CZT has been investigated for many potential uses in medical imaging, especially in the field of single photon emission computed tomography (SPECT). CZT can also be used in positron emission tomography (PET) as well as photon-counting and integration-mode x-ray radiography and computed tomography (CT). The principal advantages of CZT are 1) direct conversion of x-ray or gamma-ray energy into electron-hole pairs; 2) energy resolution; 3) high spatial resolution and hence high space-bandwidth product; 4) room temperature operation, stable performance, high density, and small volume; 5) depth-of-interaction (DOI) available through signal processing. These advantages will be described in detail with examples from our own CZT systems. The ability to operate at room temperature, combined with DOI and very small pixels, make the use of multiple, stationary CZT "mini-gamma cameras" a realistic alternative to today's large Anger-type cameras that require motion to obtain tomographic sampling. The compatibility of CZT with Magnetic Resonance Imaging (MRI)-fields is demonstrated for a new type of multi-modality medical imaging, namely SPECT/MRI. For pre-clinical (i.e., laboratory animal) imaging, the advantages of CZT lie in spatial and energy resolution, small volume, automated quality control, and the potential for DOI for parallax removal in pinhole imaging. For clinical imaging, the imaging of radiographically dense breasts with CZT enables scatter rejection and hence improved contrast. Examples of clinical breast images with a dual-head CZT system are shown.

    Several techniques are used to limit the progression of eutrophication in lakes and ponds, and to reduce its main negative effects. One of these techniques consists in maintaining oxidant conditions in deeper water layers of lakes and ponds, and, thus, to reduce or even prevent the release of harmful substances, which would result in higher water treatment costs. This technique, called aeration by the-stratification, consists of the creation of one or several local air curtains, which generate an air life effect, leading water to circulate from bottom to surface and vice-versa. This process is calculated in order to prevent thermal stratification during the warm seasons. Contacting the air at the surface of the pond oxygenates water, the oxygen levels remaining constant throughout the entire water column. (Author)

    In the following paper we explore some of the ways in which competitive intelligence and game theory can be employed to assist firms in deciding whether or not to undertake international market diversification and whether or not there is an advantage to being a market leader or a market follower overseas. In attempting to answer these questions, we take a somewhat unconventional approach. We first examine how some of the most recent advances in the physical and biological sciences can contribute to the ways in which we understand how firms behave. Subsequently, we propose a formal methodology for competitive intelligence. While space considerations here do not allow for a complete game-theoretic treatment of competitive intelligence and its use with respect to understanding first and second mover advantage in firm internationalization, that treatment can be found in its entirety in the on-line proceedings of the 6th International Conference on Complex Systems at http://knowledgetoday.org/wiki/indec.php/ICCS06/89

    Background. The MammoSite radiotherapy system is an alternative treatment option for patients with early-stage breast cancer to overcome the longer schedules associated with external beam radiation therapy. The device is placed inside the breast surgical cavity and inflated with a combination of saline and radiographic contrast to completely fill the cavity. The treatment schedule for the MammoSite monotherapy is 34 Gy delivered in 10 fractions at 1.0 cm from the balloon surface with a minimum of 6 hours between fractions on the same day. Material and methods. This review article presents the advantages, disadvantages, uncertainties and clinical outcomes associated with the MammoSite brachytherapy (MSB). Results. Potential advantages of MSB are: high localised dose with rapid falloff for normal tissue sparing, minimum delay between surgery and RT, catheter moves with breast, improved local control, no exposure to staff, likely side-effects reduction and potential cost/time saving (e.g. for country patients). The optimal cosmetic results depend on the balloon-to-skin distance. Good-to-excellent cosmetic results are achieved for patients with balloon-skin spacing of =7 mm. There have been very few published data regarding the long term tumour control and cosmesis associated with the MSB. The available data on the local control achieved with the MSB were comparable with other accelerated partial breast irradiation techniques. The contrast medium inside the balloon causes dose reduction at the prescription point. Current brachytherapy treatment planning systems (BTPS) do not take into account the increased photon attenuation due to high Z of contrast. Some BTPS predicted up to 10% higher dose near the balloon surface compared with Monte Carlo calculations using various contrast concentrations (5-25%). Conclusion. Initial clinical results have shown that the MammoSite device could be used as a sole radiation treatment for selected patients with early stage breast cancer

  19. Advantages of going modular in HTRs

    Reutler, H.; Lohnert, G.H.

    1984-01-01

    A multitude of problems that are encountered in large HTR power plans, constructively as well as concerning plant safety, can be related to the mere physical size of a large reactor core. In limiting the thermal power of an HTR-module to approximately 200 MW an inherent limitation of the fuel element temperature below critical values can be guaranteed for all possible core heat up accidents. Consequently, a significant failure rate of coated particles can be excluded and, hence, out of physical reasons, no intolerable fission product release from the core will ever have to be considered. The HTR-module is so qualified and very well suited for all possible plant sides which have to be taken into consideration for medium sized plants for the production of process steam and electricity. The cost investigations show considerable cost advantages for modular HTRs. For German conditions it was found that even a four-modular plant (800 MW/thermal) is competitive with a fossile-fueled plant of the same size, the specific plant costs were evaluated to be DM 4700/kW (electric). Moreover the investigations show that the increase of the power of the modular unit yields only small cost advantages, therefore in a modularized power plant it even would be possible to reduce the power of a modular unit below 200 MW without having to cope with severe economic penalties, if the distance from technological or safety limits is felt to be too small.

    2006-01-01

    The advantages and limitations of radiological digital images in comparison with analogic ones are analyzed. We discuss three main topics: acquisition, post-procedure manipulation, and visualization, archive and communication. Digital acquisition with computed radiology systems present a global sensitivity very close to conventional film for diagnostic purposes. However, flat panel digital systems seems to achieve some advantages in particular clinical situations. A critical issue is the radiation dose-reduction that can be accomplished without reducing image quality nor diagnostic exactitude. The post-procedure manipulation allows, particularly in multiplanar modalities like CT or MR, to extract all implicit diagnostic information in the images: Main procedures are multiplanar and three-dimensional reformations, dynamic acquisitions, functional studies and image fusion. The use of PACS for visualization, archive and communication of images, improves the effectiveness and the efficiency of the workflow, allows a more comfortable diagnosis for the radiologist and gives way to improvements in the communication of images, allowing tele consulting and the tele radiology.

    Full Text Available The article is aimed at systematization and development of a conceptual-categorical apparatus of the essence of competitive advantages. The approaches to their interpretation have been allocated. The essential characteristics and stages of the life cycle of competitive advantages are considered. As active stages it is suggested to consider the following: formation, implementation, and development. The basic properties of competitive advantages such as dual character have been substantiated and supplemented. Both the factor and the effective nature of competitive advantages are characterized. On the basis of the mentioned approaches together with the identified features, a definition of the concept of «competitive advantages» as economic category has been proposed. Its use as a base along with taking into consideration the functional specificity of trade enterprises has allowed: clarifying the essence of competitive advantages of retail enterprises; suggesting their definition as a factor and as a result of competitive relations. The identification of dual character will increase the possibilities to assess competitive advantages. Prospects for further researches in this direction are connected with allocating of peculiarities and kinds of competitive advantages of retail trade enterprises with the purpose of increasing the of validity of decisions on their formation, implementation, and development.

    Salps are marine invertebrates comprising multiple jet-propelled swimming units during a colonial life-cycle stage. Using theory, we show that asynchronous swimming with multiple pulsed jets yields substantial hydrodynamic benefit due to the production of steady swimming velocities, which limit drag. Laboratory comparisons of swimming kinematics of aggregate salps ( Salpa fusiformis and Weelia cylindrica ) using high-speed video supported that asynchronous swimming by aggregates results in a smoother velocity profile and showed that this smoother velocity profile is the result of uncoordinated, asynchronous swimming by individual zooids. In situ flow visualizations of W. cylindrica swimming wakes revealed that another consequence of asynchronous swimming is that fluid interactions between jet wakes are minimized. Although the advantages of multi-jet propulsion have been mentioned elsewhere, this is the first time that the theory has been quantified and the role of asynchronous swimming verified using experimental data from the laboratory and the field. © 2017 The Author(s).

    Understanding the fundamental patterns and determinants of human cooperation and the maintenance of social order in human societies is a challenge across disciplines. The existing empirical evidence for the higher levels of cooperation when altruistic punishment is present versus when it is absent systematically ignores the institutional competition inherent in human societies. Whether punishment would be deliberately adopted and would similarly enhance cooperation when directly competing with nonpunishment institutions is highly controversial in light of recent findings on the detrimental effects of punishment. We show experimentally that a sanctioning institution is the undisputed winner in a competition with a sanction-free institution. Despite initial aversion, the entire population migrates successively to the sanctioning institution and strongly cooperates, whereas the sanction-free society becomes fully depopulated. The findings demonstrate the competitive advantage of sanctioning institutions and exemplify the emergence and manifestation of social order driven by institutional selection.

    Full Text Available In this paper we study neural responses to inequitable distributions of rewards despite equal performance. We specifically focus on differences between advantageous (AI and disadvantageous inequity (DI. AI and DI were realized in a hyperscanning fMRI experiment with pairs of subjects simultaneously performing a task in adjacent scanners and observing both subjects' rewards. Results showed i hypoactivation of the ventral striatum under DI but not under AI; ii inequity induced activation of medial and dorsolateral prefrontal regions, that were stronger under DI than AI; iii correlations between subjective evaluations of DI and amygdala activity, and between AI evaluation and right ventrolateral prefrontal activity. Our study provides neurophysiological evidence for different cognitive processes that occur when exposed to DI and AI, respectively. Our data is compatible with the assumption that any form of inequity represents a norm violation, but that important differences between AI and DI emerge from an asymmetric involvement of status concerns.

    Acceleration of a common car with with a turbocharged diesel engine is compared to the same type with an electric motor in terms of kinematics. Starting from a state of rest, the electric car reaches a distant spot earlier than the diesel car, even though the latter has a better specification for engine power and average acceleration from 0 to 100 km h-1. A three phase model of acceleration as a function of time fits the data of the electric car accurately. The first phase is a quadratic growth of acceleration in time. It is shown that the tenfold higher coefficient for the first phase accounts for most of the kinematic advantage of the electric car.

    Full Text Available Despite rapid and sustained development of electronic commerce, many companies doing e-business are still in the investment and brand-building phase and have yet to show a profit. However, as e-businesses shift their focus from  building a customer base to increasing revenue growth and profitability, they should reevaluate their current business strategies, if any, and develop strategies that provide a clear path to profitability. This study uses McCarthy’s four marketing mix model and Porter’s five competitive forces model to identify strategies for Internet companies that respond to the five competitive forces and thereby achieve a competitive advantage. The study provides significant new insights into the development and implementation of e-business strategies that contribute to increased profit.

    In 1992, a preoperative education program was developed for total joint replacement patients in a small community hospital. The goals of the program were to increase educational opportunities for the joint replacement patients, prepare patients for hospitalization, plan for discharge needs, and increase efficiency of the orthopaedic program. Since 1992, approximately 600 patients have attended the education program. Outcomes have included positive responses from patients regarding their preparedness for surgery, increased participation in their plan of care, coordinated discharge planning, decreased length of stay, and progression across the continuum of care. A multidisciplinary approach to preparing patients for surgery allows for a comprehensive and efficient education program. Marketing of successful programs can enhance an institution's competitive advantage and help ensure the hospital's viability in the current health care arena.

    Sugimoto, Cassidy R; Ni, Chaoqun; West, Jevin D; Larivière, Vincent

    2015-01-01

    We analyzed gender disparities in patenting by country, technological area, and type of assignee using the 4.6 million utility patents issued between 1976 and 2013 by the United States Patent and Trade Office (USPTO). Our analyses of fractionalized inventorships demonstrate that women's rate of patenting has increased from 2.7% of total patenting activity to 10.8% over the nearly 40-year period. Our results show that, in every technological area, female patenting is proportionally more likely to occur in academic institutions than in corporate or government environments. However, women's patents have a lower technological impact than that of men, and that gap is wider in the case of academic patents. We also provide evidence that patents to which women--and in particular academic women--contributed are associated with a higher number of International Patent Classification (IPC) codes and co-inventors than men. The policy implications of these disparities and academic setting advantages are discussed.

  12. Costs and advantages of nuclear energy

    2006-01-01

    Recent studies on nuclear energy competitiveness show that considering only the economics this option is the most economic one to generate the base load electricity in most of the countries which do not have plenty of alternative fuels, being this advantage both for the actual prices formation and for their stability on the long term. Should we add the strategic and environmental benefits linked to: Kioto emissions limits, short and long term supply security, national wealth increase due to quality and price of the supply and enhancement of related enterprises, the goodness of nuclear energy to supply a significant share of the electricity demand in most of the countries is evident. For the investors to make decisions for this option, some conditions have to be assured: regulatory stability, favourable national energy policy and expectation for the future, predictable and proven licensing process and expectation for moderate interest rates in the long term.

    Virtual museum refers to display and simulate the functions of real museum on the Internet in the form of 3 Dimensions virtual reality by applying interactive programs. Based on Virtual Reality Modeling Language, virtual museum building and its effective interaction with the offline museum lie in making full use of 3 Dimensions panorama technique, virtual reality technique and augmented reality technique, and innovatively taking advantages of dynamic environment modeling technique, real-time 3 Dimensions graphics generating technique, system integration technique and other key virtual reality techniques to make sure the overall design of virtual museum.3 Dimensions panorama technique, also known as panoramic photography or virtual reality, is a technique based on static images of the reality. Virtual reality technique is a kind of computer simulation system which can create and experience the interactive 3 Dimensions dynamic visual world. Augmented reality, also known as mixed reality, is a technique which simulates and mixes the information (visual, sound, taste, touch, etc.) that is difficult for human to experience in reality. These technologies make virtual museum come true. It will not only bring better experience and convenience to the public, but also be conducive to improve the influence and cultural functions of the real museum.

    The use of CT volume-rendering techniques allows the evaluation of visceral organs without the need for endoscopy. Conventional endoscopic evaluation of the bladder is limited by the invasiveness of the technique and the difficulty exploring the entire bladder. Virtual evaluation of the bladder by three-dimensional CT reconstruction offers potential advantages and can be used in place of endoscopy. This study investigates the sensitivity of virtual CT in assessing lesion of the bladder wall to compare it with that of conventional endoscopy, and outlines the indications, advantages and disadvantages of virtual CT-pneumocystography. Between September 2001 and May 2002, 21 patients with haematuria and positive cystoscopic findings were studied. After an initial assessment by ultrasound, the patients underwent pelvic CT as a single volumetric scan after preliminary air distension of the bladder by means of 12 F Foley catheter. The images were processed on an independent workstation (Advantage 3.0 GE) running dedicated software for endoluminal navigation. The lesions detected by endoscopy were classified as sessile or pedunculated, and according to size (more or less than 5 mm). Finally, the results obtained at virtual cystoscopy were evaluated by two radiologists blinded to the conventional cystoscopy results. Thirty lesions (24 pedunculated, 6 sessile) were detected at conventional cystoscopy in 16 patients (multiple polyposis in 3 cases). Virtual cystoscopy identified 23 lesions (19 pedunculated and 4 sessile). The undetected lesions were pedunculated <5 mm (5 cases) and sessile (2 cases). One correctly identified pedunculated lesion was associated with a bladder stone. Good quality virtual images were obtained in all of the patients. In only one patient with multiple polyposis the quality of the virtual endoscopic evaluation was limited by the patient's intolerance to bladder distension, although identification of the lesions was not compromised.

    Rising income inequality is a global trend. Increased income inequality has been associated with higher rates of crime, greater consumer debt, and poorer health outcomes. The mechanisms linking inequality to poor outcomes among individuals are poorly understood. This research tested a behavioral account linking inequality to individual decision making. In three experiments ( n = 811), we found that higher inequality in the outcomes of an economic game led participants to take greater risks to try to achieve higher outcomes. This effect of unequal distributions on risk taking was driven by upward social comparisons. Next, we estimated economic risk taking in daily life using large-scale data from internet searches. Risk taking was higher in states with greater income inequality, an effect driven by inequality at the upper end of the income distribution. Results suggest that inequality may promote poor outcomes, in part, by increasing risky behavior.

    2010-10-01

    This article aims to reflect on which areas or tasks of microbiology laboratories could be unified with those of clinical biochemistry, hematology, immunology or pathology laboratories to benefit patients and the health system, as well as the areas that should remain independent since their amalgamation would not only fail to provide a benefit but could even jeopardize the quality of microbiological diagnosis, and consequently patient care. To do this, the distinct analytic phases of diagnosis are analyzed, and the advantages and disadvantages of amalgamation are evaluated in each phase. The pros and cons of the unification of certain areas such as the computer system, occupational risk units, customer service, purchasing logistics, and materials storage, etc, are also discussed. Lastly, the effect of unification on urgent microbiology diagnosis is analyzed. Microbiological diagnosis should be unique. The microbiologist should perform an overall evaluation of the distinct techniques used for a particular patient, both those that involve direct diagnosis (staining, culture, antigen detection techniques or molecular techniques) and indirect diagnosis (antibody detection). Moreover, the microbiology laboratory should be independent, with highly trained technicians and specialists in microbiology that provide added value as experts in infection and as key figures in the process of establishing a correct etiological diagnosis.

    A significant amount of antimony (Sb) enters into the environment every year because of the wide use of Sb compounds in industry and agriculture. The exposure to Sb, either direct consumption of Sb or indirectly, may be fatal to the human health because both antimony and antimonide are toxic. Firstly, the introduction of Sb chemistry, distribution and health threats are presented in this review, which is essential to the removal techniques. Then, we provide the recent and common techniques to remove Sb, including adsorption, coagulation/flocculation, membrane separation, electrochemical methods, ion exchange and extraction. Removal techniques concentrate on the advantages, drawbacks, economical efficiency and the recent achievements of each technique. We also take an overall consideration of experimental conditions, comparison criteria, and economic aspects. Copyright © 2018 Elsevier Inc. All rights reserved.

  2. How can we take advantage of halophyte properties to cope with heavy metal toxicity in salt-affected areas?

    Lutts, Stanley; Lefèvre, Isabelle

    2015-01-01

    Background Many areas throughout the world are simultaneously contaminated by high concentrations of soluble salts and by high concentrations of heavy metals that constitute a serious threat to human health. The use of plants to extract or stabilize pollutants is an interesting alternative to classical expensive decontamination procedures. However, suitable plant species still need to be identified for reclamation of substrates presenting a high electrical conductivity. Scope Halophytic plant species are able to cope with several abiotic constraints occurring simultaneously in their natural environment. This review considers their putative interest for remediation of polluted soil in relation to their ability to sequester absorbed toxic ions in trichomes or vacuoles, to perform efficient osmotic adjustment and to limit the deleterious impact of oxidative stress. These physiological adaptations are considered in relation to the impact of salt on heavy metal bioavailabilty in two types of ecosystem: (1) salt marshes and mangroves, and (2) mine tailings in semi-arid areas. Conclusions Numerous halophytes exhibit a high level of heavy metal accumulation and external NaCl may directly influence heavy metal speciation and absorption rate. Maintenance of biomass production and plant water status makes some halophytes promising candidates for further management of heavy-metal-polluted areas in both saline and non-saline environments.

    The DNA damage response (DDR) is a complex signalling network activated when DNA is altered by intrinsic or extrinsic agents. DDR plays important roles in genome stability and cell cycle regulation, as well as in tumour transformation. Viruses have evolved successful life cycle strategies in order to ensure a chronic persistence in the host, virtually avoiding systemic sequelae and death. This process promotes the periodic shedding of large amounts of infectious particles to maintain a virus reservoir in individual hosts, while allowing virus spreading within the community. To achieve such a successful lifestyle, the human papilloma virus (HPV) needs to escape the host defence systems. The key to understanding how this is achieved is in the virus replication process that provides by itself an evasion mechanism by inhibiting and delaying the host immune response against the viral infection. Numerous studies have demonstrated that HPV exploits both the ataxia-telangiectasia mutated (ATM) and ataxia-telangiectasia and rad3-related (ATR) DDR pathways to replicate its genome and maintain a persistent infection by downregulating the innate and cell-mediated immunity. This review outlines how HPV interacts with the ATM- and ATR-dependent DDR machinery during the viral life cycle to create an environment favourable to viral replication, and how the interaction with the signal transducers and activators of transcription (STAT) protein family and the deregulation of the Janus kinase (JAK)-STAT pathways may impact the expression of interferon-inducible genes and the innate immune responses.

    Science education research suggests that our everyday intuitions of motion and interaction of physical objects fit well with how physicists use the term "momentum". Corpus linguistics provides an easily accessible approach to study language in different domains, including everyday language. Analysis of language samples from English text corpora reveals a trend of increasing metaphorical use of "momentum" in non-science domains, and through conceptual metaphor analysis, we show that the use of the word in everyday language, as opposed to for instance "force", is largely adequate from a physics point of view. In addition, "momentum" has recently been borrowed into Swedish as a metaphor in domains such as sports, politics and finance, with meanings similar to those in physics. As an implication for educational practice, we find support for the suggestion to introduce the term "momentum" to English-speaking pupils at an earlier age than what is typically done in the educational system today, thereby capitalising on their intuitions and experiences of everyday language. For Swedish-speaking pupils, and possibly also relevant to other languages, the parallel between "momentum" and the corresponding physics term in the students' mother tongue could be made explicit..

    The standardized infection ratio (SIR) evaluates individual publicly reported health care-associated infections, but it may not assess overall performance. We piloted an infection composite score (ICS) in 82 hospitals of a single health system. The ICS is a combined score for central line-associated bloodstream infections, catheter-associated urinary tract infections, colon and abdominal hysterectomy surgical site infections, and hospital-onset methicillin-resistant Staphylococcus aureus bacteremia and Clostridium difficile infections. Individual facility ICSs were calculated by normalizing each of the 6 SIR events to the system SIR for baseline and performance periods (ICS ib and ICS ip , respectively). A hospital ICS ib reflected its baseline performance compared with system baseline, whereas a ICS ip provided information of its outcome changes compared with system baseline. Both the ICS ib (baseline 2013) and ICS ip (performance 2014) were calculated for 63 hospitals (reporting at least 4 of the 6 event types). The ICS ip improved in 36 of 63 (57.1%) hospitals in 2014 when compared with the ICS ib in 2013. The ICS ib 2013 median was 0.96 (range, 0.13-2.94) versus the 2014 ICS ip median of 0.92 (range, 0-6.55). Variation was more evident in hospitals with ≤100 beds. The system performance score (ICS sp ) in 2014 was 0.95, a 5% improvement compared with 2013. The proposed ICS may help large health systems and state hospital associations better evaluate key infectious outcomes, comparing them with historic and concurrent performance of peers.

    Godoy, E.; Benz, S.J.; Scenna, N.J.

    2011-01-01

    Optimal combined cycle gas turbine power plants characterized by minimum specific annual cost values are here determined for wide ranges of market conditions as given by the relative weights of capital investment and operative costs, by means of a non-linear mathematical programming model. On the other hand, as the technical optimization allows identifying trends in the system behavior and unveiling optimization opportunities, selected functional relationships are obtained as the thermodynamic optimal values of the decision variables are systematically linked to the ratio between the total heat transfer area and the net power production (here named as specific transfer area). A strategy for simplifying the resolution of the rigorous economic optimization problem of power plants is proposed based on the economic optima distinctive characteristics which describe the behavior of the decision variables of the power plant on its optima. Such approach results in a novel mathematical formulation shaped as a system of non-linear equations and additional constraints that is able to easily provide accurate estimations of the optimal values of the power plant design and operative variables. Research highlights: → We achieve relationships between power plants' economic and thermodynamic optima. → We achieve functionalities among thermodynamic optimal values of decision variables. → The rigorous optimization problem is reduced to a non-linear equations system. → Accurate estimations of power plants' design and operative variables are obtained.

    With the advent of Internet-based 24-hour recall (24HR) instruments, it is now possible to envision their use in cohort studies investigating the relation between nutrition and disease. Understanding that all dietary assessment instruments are subject to measurement errors and correcting for them under the assumption that the 24HR is unbiased for usual intake, here the authors simultaneously address precision, power, and sample size under the following 3 conditions: 1) 1-12 24HRs; 2) a single calibrated food frequency questionnaire (FFQ); and 3) a combination of 24HR and FFQ data. Using data from the Eating at America\\'s Table Study (1997-1998), the authors found that 4-6 administrations of the 24HR is optimal for most nutrients and food groups and that combined use of multiple 24HR and FFQ data sometimes provides data superior to use of either method alone, especially for foods that are not regularly consumed. For all food groups but the most rarely consumed, use of 2-4 recalls alone, with or without additional FFQ data, was superior to use of FFQ data alone. Thus, if self-administered automated 24HRs are to be used in cohort studies, 4-6 administrations of the 24HR should be considered along with administration of an FFQ.

    We explored the evolution from cigarette product attributes to psychosocial needs in advertising campaigns for low-tar cigarettes. Analysis of previously secret tobacco industry documents and print advertising images indicated that low-tar brands targeted smokers who were concerned about their health with advertising images intended to distract them from the health hazards of smoking. Advertising first emphasized product characteristics (filtration, low tar) that implied health benefits. Over time, advertising emphasis shifted to salient psychosocial needs of the target markets. A case study of Vantage cigarettes in the USA and Canada showed that advertising presented images of intelligent, upward-striving people who had achieved personal success and intentionally excluded the act of smoking from the imagery, while minimal product information was provided. This illustrates one strategy to appeal to concerned smokers by not describing the product itself (which may remind smokers of the problems associated with smoking), but instead using evocative imagery to distract smokers from these problems. Current advertising for potential reduced-exposure products (PREPs) emphasizes product characteristics, but these products have not delivered on the promise of a healthier alternative cigarette. Our results suggest that the tobacco control community should be on the alert for a shift in advertising focus for PREPs to the image of the user rather than the cigarette. Global Framework Convention on Tobacco Control-style advertising bans that prohibit all user imagery in tobacco advertising could preempt a psychosocial needs-based advertising strategy for PREPs and maintain public attention on the health hazards of smoking.

The development of molecular probes that specifically bind biochemical markers and the advances of instrumentation have revolutionized the possibilities to gain insight into the human brain organization and beyond this-visualize structure-function and brain-behavior relationships. The review describes the development and current applications of functional brain imaging techniques with a focus on applications in psychiatry. A historical overview of the development of functional imaging is followed by the portrayal of the principles and applications of positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), two key molecular imaging techniques that have revolutionized the ability to image molecular processes in the brain. We conclude that the juxtaposition of PET and fMRI in hybrid PET/MRI scanners enhances the significance of both modalities for research in neurology and psychiatry and might pave the way for a new area of personalized medicine.

    Full Text Available This paper is focused on general properties of straw bale as a building material which has been proven by buildings throughout the world to be an appropriate material choice. Still, there are many hesitations about using this alternative building material. The building techniques are relatively easy to learn and the performance of straw bale structures has a high value in terms of several aspects as long as general requirements are followed. The primary benefit of straw bale as a building material is its low embodied energy. It also has high thermal and sound insulation properties. Many previous research studies on straw bale building have been focused on structural stability, fire resistance and assessing moisture content in straw bales which is one of the major issues. Therefore, special attention needs to be devoted to details to insure proper building safety. Render selection is especially crucial and an extremely important step in straw bale building, not only in matters concerning moisture but also structural capacity and fire protection. A major disadvantage of straw bale construction is its lack of material research. The paper is divided into three parts in which advantages and disadvantages of such a building are discussed. In the third part, results are presented for a survey in which correspondents emphasized the advantages and disadvantages of living in a straw bale building.

    To describe Single Incision Pediatric Endoscopic Surgery (SIPES) performed on children with various diagnoses, emphasizing its advantages. Study Design: An observational case series. Place and Duration of Study: Department of Pediatric Surgery, Dr. Sami Ulus Maternity and Child Health Hospital, Ankara, Turkey, from January 2011 to November 2014. Methodology: A review of patient charts was conducted in which SIPES was preferred as the surgical procedure. Patient demographics, operative details, operative time, clinical outcomes, postoperative pain and cosmesis were analyzed. Results: SIPES was performed on 45 patients (21 girls, 24 boys). Thirty-three appendectomies, 5 varicocelectomies, 3 oophorectomies, 2 ovarian and one paratubal cyst excision, and one fallopian tube excision were performed. All except one procedures were performed through our standard 2cm umbilical vertical or smile incision. In 18 cases, abdominal irrigation/aspiration was easily performed through the existing larger incision, as is done with open surgical technique. None of the patients had early postoperative shoulder/back pain since complete disinflation of CO/sub 2/ could be ensured. All of the patients/parents were satisfied with the cosmesis. Conclusion: SIPES has the advantages of limiting the surgical scar to within the umbilicus and providing easy disinflation of CO/sub 2/, allowing intraabdominal cleaning and extraction of large volume tissue samples through a single large umbilical incision.

    Millimeter-wave gyrotron collective Thomson scattering can be an effective diagnostic technique for the study of alpha particle behavior in ignited plasmas. The measurement of alpha particle density, velocity distribution, and alpha particle induced plasma instabilities can be accomplished with both spatial and temporal resolution. Advantages include long pulse operation which can make possible very high signal to noise ratios and use of millimeter waves which maximizes the Doppler shifted scattered signal in WHz -1 and makes possible scattering angles up to 180 0 . Extraordinary mode scattering at approximately 60 and 200 GHz would be used in TFTR and CIT respectively, and 140 GHz ordinary mode scattering in JET. 8 refs., 1 fig

    Full Text Available With the expansion of globalization, economic integration and the mobility of production factors at the local and global level have been facilitated. In Europe, the process of economic and monetary integration began when barriers to the free movement of goods, capital and labor were formally abolished, although cultural barriers still exist. The need and justification of tax competition is that it can lead to greater efficiency in the use of public sector resources and more efficient allocation of capital. The main advantages of tax competition are those related to the reduction of tax rates, which can lead to boosting consumption and investment. The method used to achieve the objective is complex, from statistical and economic analyzes of fiscal data to a comparative technique at the level of the European Union. The database used is from Eurostat sources and other European Commission work on taxation in the Member States of the European Union.

    1976-01-01

    The use of high intensity glow-discharge permits to realize a superficial thermochemical treatment. Ions formed by discharge are accelerated against the surfaces to be treated; by effect of ion bombardment, surfaces get heated and a chemical reaction is developed depending on the composition of the ionized gas. The technique presents advantages, as the potential of the active gas might be freely chosen, and as many gases might be used, the decomposition of gases by pyrolysis and a homogeneous treatment (concerning nature of phases and thickness) all over the surface being not necessary. It is possible to develop layers of various nature, looking for those which offer the best properties to solve a technological problem (wear, friction, fatigue toughness, etc.). Some examples of nitruration, carbonitruration are considered [fr

  6. The Academic Advantage: Gender Disparities in Patenting

    Sugimoto, Cassidy R.; Ni, Chaoqun; West, Jevin D.; Larivière, Vincent

    2015-01-01

    We analyzed gender disparities in patenting by country, technological area, and type of assignee using the 4.6 million utility patents issued between 1976 and 2013 by the United States Patent and Trade Office (USPTO). Our analyses of fractionalized inventorships demonstrate that women’s rate of patenting has increased from 2.7% of total patenting activity to 10.8% over the nearly 40-year period. Our results show that, in every technological area, female patenting is proportionally more likely to occur in academic institutions than in corporate or government environments. However, women’s patents have a lower technological impact than that of men, and that gap is wider in the case of academic patents. We also provide evidence that patents to which women—and in particular academic women—contributed are associated with a higher number of International Patent Classification (IPC) codes and co-inventors than men. The policy implications of these disparities and academic setting advantages are discussed. PMID:26017626

    Difficult or unsuccesful tracheal intubation is one of the important causes for morbidity and mortality in susceptible patients. Almost 30% of the anesthesia-related deaths are induced by the complications of difficult airway management and more than 85% of all respiratory related complications cause brain injury or death. Nowadays, due to the advances in technology, new videolaryngoscopic devices became available. Airtraq is a novel single-use laryngoscope which provides glottis display without any deviation in the normal position of the oral, pharyngeal or the tracheal axes. With the help of the display lens glottis and the surrounding structures are visualised and under direct view of its tip the tracheal tube is introduced between the vocal cords. In patients having restricted neck motion or limited mouth opening (provided that it is greater than 3 cm) Airtraq offers the advantage of a better display. Moreover the video image can be transfered to an external monitor thus an experienced specialist can provide assistance and an educational course can be conducted simultaneously. On the other hand the Airtraq videolaryngoscopic devices possess certain disadvantages including the need of experience and the time demand for the operator to learn how to use them properly, the rapid deterioration of their display in the presence of a swelling or a secretion and the fact that they are rather complicated and expensive devices. The Airtraq device has already documented benefits in the management of difficult airways, however serial utilization obviously necessitates experience.

    High critical temperature superconductors have zero power consumption and could be used to produce ideal electric power lines. The principal obstacle in fabricating superconducting wires and tapes is grain boundaries—the misalignment of crystalline orientations at grain boundaries, which is unavoidable for polycrystals, largely deteriorates critical current density. Here we report that high critical temperature iron pnictide superconductors have advantages over cuprates with respect to these grain boundary issues. The transport properties through well-defined bicrystal grain boundary junctions with various misorientation angles (θGB) were systematically investigated for cobalt-doped BaFe2As2 (BaFe2As2:Co) epitaxial films fabricated on bicrystal substrates. The critical current density through bicrystal grain boundary (JcBGB) remained high (>1 MA cm−2) and nearly constant up to a critical angle θc of ∼9°, which is substantially larger than the θc of ∼5° for YBa2Cu3O7–δ. Even at θGB>θc, the decay of JcBGB was much slower than that of YBa2Cu3O7–δ. PMID:21811238

    2010-01-01

    Prochlorococcus is the key phytoplanktonic organism of tropical gyres, large ocean regions that are depleted of the essential macronutrients needed for photosynthesis and cell growth. This cyanobacterium has adapted itself to oligotrophy by minimizing the resources necessary for life through a drastic reduction of cell and genome sizes. This rarely observed strategy in free-living organisms has conferred on Prochlorococcus a considerable advantage over other phototrophs, including its closest relative Synechococcus, for life in this vast yet little variable ecosystem. However, this strategy seems to reach its limits in the upper layer of the S Pacific gyre, the most oligotrophic region of the world ocean. By losing some important genes and/or functions during evolution, Prochlorococcus has seemingly become dependent on co-occurring microorganisms. In this review, we present some of the recent advances in the ecology, biology, and evolution of Prochlorococcus, which because of its ecological importance and tiny genome is rapidly imposing itself as a model organism in environmental microbiology.

  11. Grounding Animal Rights in Mutual Advantage Contractarianism

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Contrary to critics and advocates of contractarianism alike, I argue that mutual advantage contractarianism entails rights and protections for animals. In section one I outline the criteria that must be met in order for an individual to qualify for moral rights on the contractarian view. I then introduce an alternative form of ‘rights,’ which I call ‘protectorate status,’ from which an individual can receive protections indirectly. In section two I suggest guidelines for assigning animal rights based on two ways of categorizing animals. On the basis of the categorization according to benefit derived, I argue that animals used for companionship, security, hunting assistance, transportation, entertainment, medical service, nourishment, or clothing will tend to qualify for basic rights against starvation, predation, and disease. On the basis of the categorization according to species, I argue that, on top of the basic rights above, dogs tend to qualify for rights against abuse, and against frivolous medical experimentation, as well as further negotiated rights. Cows have the basic rights against starvation, predation, and disease, but squirrels and bears have no rights. In section three I argue that some animals qualify for protectorate status, which would establish various protections for different animals, but would also generally prohibit cruelty towards animals.

    Owing to their excellent dosimetric properties, luminescence detectors of ionizing radiation are now extensively applied in individual dosimetry services. The most frequently used personal dosemeters are based on Optically Stimulated Luminescence (OSL), radiophotoluminescence (RPL) or thermoluminescence (TL). Luminescence detectors have also found several applications in clinical dosimetry, especially around new radiation modalities in radiotherapy, such as Intensity Modulated Radiotherapy (IMRT) or ion beam radiotherapy. Requirements of luminescence detectors applied in individual and clinical dosimetry and some recent developments in luminescence of detectors and techniques leading to significant improvements of the functionality and accuracy of dosimetry systems are reviewed and discussed.

    Electromagnetic strange particle production developed at Jefferson Laboratory was an important source of information on strange particle electromagnetic formfactors and induced and transferred polarization. The high quality of the beam and the detection techniques involved could be an argument for detecting strange particles in weak interactions and answer questions about cross sections, weak formfactors, neutrino properties, which have not been investigated yet. The paper analyses some aspects related to the weak lambda production and detection with the Hall C facilities at Jefferson Laboratory and the limitations in measuring the weak interaction quantities.

  17. [The precautionary principle: advantages and risks].

    Tubiana, M

    2001-04-01

    The extension of the precautionary principle to the field of healthcare is the social response to two demands of the population: improved health safety and the inclusion of an informed public in the decision-making process. The necessary balance between cost (treatment-induced risk) and benefit (therapeutic effect) underlies all healthcare decisions. An underestimation or an overestimation of cost, i.e. risk, is equally harmful in public healthcare. A vaccination should be prescribed when its beneficial effect outweighs its inevitable risk. Mandatory vaccination, such as in the case of the Hepatitis B virus, is a health policy requiring some courage because those who benefit will never be aware of its positive effect while those who are victims of the risk could resort to litigation. Defense against such accusations requires an accurate assessment of risk and benefit, which underlines the importance of expertise. Even within the framework of the precautionary principle, it is impossible to act without knowledge, or at least a plausible estimation, of expected effects. Recent affairs (blood contamination, transmissible spongiform encephalitis by growth hormone, and new variant of Creutzfeldt-Jacob disease) illustrate that in such cases the precautionary principle would have had limited impact and it is only when enough knowledge was available that effective action could be taken. Likewise, in current debates concerning the possible risks of electromagnetic fields, cellular phones and radon, research efforts must be given priority. The general public understands intuitively the concept of cost and benefit. For example, the possible health risks of oral contraceptives and hormone replacement therapy were not ignored, but the public has judged that their advantages justify the risk. Estimating risk and benefit and finding a balance between risk and preventive measures could help avoid the main drawbacks of the precautionary principle, i.e. inaction and refusal of

    2007-11-01

    Full Text Available The advantages of cooperation between research library associations can be demonstrated quite clearly. Where cooperation becomes essential is where there is a common cause to champion or an initiative to pursue for the common good. Thanks in part to the power of information communications technology, research is becoming increasingly international in scope. The members of interdisciplinary and multidisciplinary research teams are frequently drawn from across the world. Correspondingly, scholarly publishing (especially in medicine and the sciences is dominated by a few multinational publishers. In this context, issues that play a vital role in global scholarly communication - such as copyright, journal pricing, the managing of datasets, digital preservation and open access - are issues for the research library community everywhere in the world. Certainly there are many challenges at the local or regional level. However there are definite roles that research library associations can play most effectively at the national or international level. It is clear that by sharing expertise, building partnerships and alliances, it is possible to address common issues much more effectively than when working alone. What is special is that potentially the most powerful form of cooperation is advocacy at the national and international levels. It is essential for research library associations to work together at the political level to move their agenda forward. Examples are lobbying about copyright legislation (nationally, or within the EC or at WIPO; or promoting the cause of Open Access. The unique value of LIBER is to provide a forum and a platform for European research library associations to explore and benefit from cooperation and their shared strength.

  19. Searching for the Advantages of Virus Sex

    Science.gov (United States)

    Turner, Paul E.

    2003-02-01

    Sex (genetic exchange) is a nearly universal phenomenon in biological populations. But this is surprising given the costs associated with sex. For example, sex tends to break apart co-adapted genes, and sex causes a female to inefficiently contribute only half the genes to her offspring. Why then did sex evolve? One famous model poses that sex evolved to combat Muller's ratchet, the mutational load that accrues when harmful mutations drift to high frequencies in populations of small size. In contrast, the Fisher-Muller Hypothesis predicts that sex evolved to promote genetic variation that speeds adaptation in novel environments. Sexual mechanisms occur in viruses, which feature high rates of deleterious mutation and frequent exposure to novel or changing environments. Thus, confirmation of one or both hypotheses would shed light on the selective advantages of virus sex. Experimental evolution has been used to test these classic models in the RNA bacteriophage φ6, a virus that experiences sex via reassortment of its chromosomal segments. Empirical data suggest that sex might have originated in φ6 to assist in purging deleterious mutations from the genome. However, results do not support the idea that sex evolved because it provides beneficial variation in novel environments. Rather, experiments show that too much sex can be bad for φ6 promiscuity allows selfish viruses to evolve and spread their inferior genes to subsequent generations. Here I discuss various explanations for the evolution of segmentation in RNA viruses, and the added cost of sex when large numbers of viruses co-infect the same cell.

    Multimodality imaging has made great strides in the imaging evaluation of patients with a variety of diseases. Positron emission tomography/computed tomography (PET/CT) is now established as the imaging modality of choice in many clinical conditions, particularly in oncology. While the initial development of combined PET/magnetic resonance imaging (PET/MRI) was in the preclinical arena, hybrid PET/MR scanners are now available for clinical use. PET/MRI combines the unique features of MRI including excellent soft tissue contrast, diffusion-weighted imaging, dynamic contrast-enhanced imaging, fMRI and other specialized sequences as well as MR spectroscopy with the quantitative physiologic information that is provided by PET. Most evidence for the potential clinical utility of PET/MRI is based on studies performed with side-by-side comparison or software-fused MRI and PET images. Data on distinctive utility of hybrid PET/MRI are rapidly emerging. There are potential competitive advantages of PET/MRI over PET/CT. In general, PET/MRI may be preferred over PET/CT where the unique features of MRI provide more robust imaging evaluation in certain clinical settings. The exact role and potential utility of simultaneous data acquisition in specific research and clinical settings will need to be defined. It may be that simultaneous PET/MRI will be best suited for clinical situations that are disease-specific, organ-specific, related to diseases of the children or in those patients undergoing repeated imaging for whom cumulative radiation dose must be kept as low as reasonably achievable. PET/MRI also offers interesting opportunities for use of dual modality probes. Upon clear definition of clinical utility, other important and practical issues related to business operational model, clinical workflow and reimbursement will also be resolved.

  12. When perspective taking increases taking: reactive egoism in social interaction.

    Science.gov (United States)

    Epley, Nicholas; Caruso, Eugene; Bazerman, Max H

    2006-11-01

    Group members often reason egocentrically, believing that they deserve more than their fair share of group resources. Leading people to consider other members' thoughts and perspectives can reduce these egocentric (self-centered) judgments such that people claim that it is fair for them to take less; however, the consideration of others' thoughts and perspectives actually increases egoistic (selfish) behavior such that people actually take more of available resources. A series of experiments demonstrates this pattern in competitive contexts in which considering others' perspectives activates egoistic theories of their likely behavior, leading people to counter by behaving more egoistically themselves. This reactive egoism is attenuated in cooperative contexts. Discussion focuses on the implications of reactive egoism in social interaction and on strategies for alleviating its potentially deleterious effects.

  13. Advantages of efficiency-aware smart charging strategies for PEVs

    Highlights: ► We analyze smart variable-rate-based charging strategies for electric vehicles. ► We consider the impact of the charging rate on the charging efficiency. ► Accounting for charging efficiency variations allows improving system performance. ► The study defines useful guidelines to develop smart battery chargers. - Abstract: Plug-in Electric Vehicles (PEVs) diffusion is expected to grow considerably over the next few years. Aiming to overcome severe grid overload problems caused by a large PEV penetration, utilities and vehicle manufactures are involved in the effort of developing ad hoc charging systems interacting in real-time with smart grids in order to implement smart energy dispatching strategies for PEVs. Strategies which take advantage of varying the charging rate during the charging process appear the most effective solution to guarantee both a full exploitation of the grid capacity and suitable degrees of user satisfaction. This work demonstrates that the actual effectiveness of variable-rate-based dispatching strategies significantly depends on the energy efficiency of the battery charging process, which is in turn strongly related to the charging rate used. Simulation results for a realistic situation show that smart efficiency-aware dispatching strategies, which take into account the actual dependence between the charging efficiency and the charging rate, allow significant improvements in both the user satisfaction and the utility profit compared with non-efficiency-aware strategies. The results of the analysis performed give useful guidelines for the development of smart-grid management policies and for the design of next-generation PEVs battery chargers and charging stations.

  14. Kinetic advantage of controlled intermediate nuclear fusion

    International Nuclear Information System (INIS)

    Guo Xiaoming

    2012-01-01

    The dominated process of controlled fusion is to let nuclei gain enough kinetic energy to overcome Coulomb barrier. As a result, a fusion scheme can consider two factors in its design: to increase kinetic energy of nuclei and to alter the Coulomb barrier. Cold Fusion and Hot fusion are all one-factor schemes while Intermediate Fusion is a twofactors scheme. This made CINF kinetically superior. Cold Fusion reduces deuteron-deuteron distance, addressing Coulomb barrier, and Hot Fusion heat up plasma into extreme high temperature, addressing kinetic energy. Without enough kinetic energy made Cold Fusion skeptical. Extreme high temperature made Hot Fusion very difficult to engineer. Because CIFN addresses both factors, CIFN is a more promising technique to be industrialized.

During the citation analysis-based selection of the world scientific serial publications apposite for a qualitative performance of research in energy security, energy conservation and energy efficient technologies and techniques with the use of the data of Journal Citation Reports® (which basic results are available at: https://figshare.com/articles/energy_sec_xlsx/5606053/2 a noticeable amount of non-serial items was also found out in addition to serial publications, as well as some publications that, though being serial, did not look typical to be used in the research activities. Individual consideration of each such “exotic” information source confirmed, however, that their noticeable citedness by the world experts in power engineering looked quite natural. Moreover, it becomes clear that these (apparently wrongly reflected in Journal Citation Reports® information sources are, however, not an “information noise”, but a useful addition to the “professional reading” of power engineering experts.

  16. The competitive advantage of corporate philanthropy.

    2002-12-01

    When it comes to philanthropy, executives increasingly see themselves as caught between critics demanding ever higher levels of "corporate social responsibility" and investors applying pressure to maximize short-term profits. In response, many companies have sought to make their giving more strategic, but what passes for strategic philanthropy is almost never truly strategic, and often isn't particularly effective as philanthropy. Increasingly, philanthropy is used as a form of public relations or advertising, promoting a company's image through high-profile sponsorships. But there is a more truly strategic way to think about philanthropy. Corporations can use their charitable efforts to improve their competitive context--the quality of the business environment in the locations where they operate. Using philanthropy to enhance competitive context aligns social and economic goals and improves a company's long-term business prospects. Addressing context enables a company to not only give money but also leverage its capabilities and relationships in support of charitable causes. The produces social benefits far exceeding those provided by individual donors, foundations, or even governments. Taking this new direction requires fundamental changes in the way companies approach their contribution programs. For example, philanthropic investments can improve education and local quality of life in ways that will benefit the company. Such investments can also improve the company's competitiveness by contributing to expanding the local market and helping to reduce corruption in the local business environment. Adopting a context-focused approach goes against the grain of current philanthropic practice, and it requires a far more disciplined approach than is prevalent today. But it can make a company's philanthropic activities far more effective.

    1997-01-01

    The capability for an ion beam to penetrate easily the matter is an original feature for the nuclear microprobe analysis when compared to other techniques. Information in death of the sample can thus be obtained. Scanning Transmission Ion Microscopy (STIM) takes advantage of this capability to provide two dimensional maps of the sample thickness. Cross-sectional images of an object may be calculated from a set of STIM projections allowing the determination of the three-dimensional structure. This is the principle of STIM-Tomography. When PIXE analysis is carried out rotating the object under investigation, the elemental 3-D chemical distribution may also be elucidated at a microscopic scale. (authors)

  19. Advantages and Challenges of Radiative Liquid Lithium Divertor

    2017-10-01

    Steady-state fusion power plant designs present major divertor technology challenges, including high divertor heat flux both in steady-state and during transients. In addition to these concerns, there are the unresolved technology issues of long term dust accumulation and associated tritium inventory and safety issues. The application of lithium (Li) in NSTX resulted in improved H-mode confinement, H-mode power threshold reduction, and reduction in the divertor peak heat flux while maintaining essentially Li-free core plasma operation even during H-modes. These promising results in NSTX and related modeling calculations motivated the radiative liquid Li divertor (RLLD) concept and its variant, the active liquid Li divertor concept (ARLLD), taking advantage of the enhanced Li radiation in relatively poorly confined divertor plasmas. It has been suggested that radiation-based liquid lithium (LL) divertor concepts with a modest Li-loop could provide a possible solution for the outstanding fusion reactor technology issues such as divertor heat flux mitigation and real time dust removal, while potentially improving the reactor plasma performance. Laboratory tests are also planned to investigate the Li-T recover efficiency and other relevant research topics of the RLLD. This work supported by DoE Contract No. DE-AC02-09CH11466.

    The quality of software is achieved during its development. Development teams use various techniques to investigate, evaluate and control potential quality problems in their systems. These “Quality Attribute Techniques” target specific product qualities such as safety or security. This paper proposes a framework to capture important characteristics of these techniques. The framework is intended to support process tailoring, by facilitating the selection of techniques for inclusion into process models that target specific product qualities. We use risk management as a theory to accommodate techniques for many product qualities and lifecycle phases. Safety techniques have motivated the framework, and safety and performance techniques have been used to evaluate the framework. The evaluation demonstrates the ability of quality risk management to cover the development lifecycle and to accommodate two different product qualities. We identify advantages and limitations of the framework, and discuss future research on the framework.

    Since the 1997 Kyoto Protocol set binding targets for greenhouse gas reductions, there has been a rapid increase in interest in emissions trading. This is based on the premise that reduction options may be cheaper in countries such as those of eastern Europe and the developing world, than in others such as the USA and Norway. As long as real emission reductions take place, and given that climate change is a global problem, setting up an emissions trading market should provide a much cheaper option than reductions applied solely at a national level. The real prospects for a viable market, what it will look like, and the deals already taking place are examined. (UK)

Although not profit-driven, libraries should leverage excellent customer service to achieve their unique missions. Evaluating and improving customer service practices will help a library determine if it is successfully serving its customers. The library should review three areas to improve customer service: the physical space of the library, how library employees work with library policies, and the communication skills of the library staff. By using the Take Five model, the library can make immediate, no-cost changes or plan for future improvements by taking just five minutes, every day, to assess specific areas. Over a few weeks or months, these small changes will result in better customer service.

  3. The Exposure Advantage: Early Exposure to a Multilingual Environment Promotes Effective Communication.

    2015-07-01

    Early language exposure is essential to developing a formal language system, but may not be sufficient for communicating effectively. To understand a speaker's intention, one must take the speaker's perspective. Multilingual exposure may promote effective communication by enhancing perspective taking. We tested children on a task that required perspective taking to interpret a speaker's intended meaning. Monolingual children failed to interpret the speaker's meaning dramatically more often than both bilingual children and children who were exposed to a multilingual environment but were not bilingual themselves. Children who were merely exposed to a second language performed as well as bilingual children, despite having lower executive-function scores. Thus, the communicative advantages demonstrated by the bilinguals may be social in origin, and not due to enhanced executive control. For millennia, multilingual exposure has been the norm. Our study shows that such an environment may facilitate the development of perspective-taking tools that are critical for effective communication. © The Author(s) 2015.

    At Lawrence Livermore National Laboratory (LLNL) we have recently developed several techniques for volume visualization of scalar and vector fields, all of which use back-to-front compositing. The first renders volume density clouds by compositing polyhedral volume cells or their faces. The second is a ''splatting'' scheme which composites textures used to reconstruct the scalar or vector fields. One version calculates the necessary texture values in software, and another takes advantage of hardware texture mapping. The next technique renders contour surface polygons using semi-transparent textures, which adjust appropriately when the surfaces deform in a flow, or change topology. The final one renders the ''flow volume'' of smoke or dye tracer swept out by a fluid flowing through a small generating polygon. All of these techniques are applied to a climate model data set, to visualize cloud density and wind velocity

  14. Novel information theory techniques for phonon spectroscopy

    International Nuclear Information System (INIS)

    Hague, J P

    2007-01-01

    The maximum entropy method (MEM) and spectral reverse Monte Carlo (SRMC) techniques are applied to the determination of the phonon density of states (PDOS) from heat-capacity data. The approach presented here takes advantage of the standard integral transform relating the PDOS with the specific heat at constant volume. MEM and SRMC are highly successful numerical approaches for inverting integral transforms. The formalism and algorithms necessary to carry out the inversion of specific heat curves are introduced, and where possible, I have concentrated on algorithms and experimental details for practical usage. Simulated data are used to demonstrate the accuracy of the approach. The main strength of the techniques presented here is that the resulting spectra are always physical: Computed PDOS is always positive and properly applied information theory techniques only show statistically significant detail. The treatment set out here provides a simple, cost-effective and reliable method to determine phonon properties of new materials. In particular, the new technique is expected to be very useful for establishing where interesting phonon modes and properties can be found, before spending time at large scale facilities

    Full Text Available Entrepreneurs work in a resource-constrained environment. What is more, the resources controlled by new ventures are often much more limited compared to the resources controlled by existing competitors. In order to overcome the gap between needed and controlled resources, entrepreneurs use techniques such as financial bootstrapping (Ebben & Johnson, 2006 and bricolage (Philips & Tracey, 2007. This study extends the concept of entrepreneurial bricolage by introducing the concept of resource hijacking, which explains how entrepreneurs take advantage of resources controlled by others to extend their resource base and develop new ventures. Using an exploratory grounded theory approach, this study aims to: (1 conceptualize resource hijacking, (2 identify different dimensions and variants of resource hijacking, (3 provide empirical evidence of resource hijacking in practice, and (4 fit the emergent concept into the existing body of literature on bootstrapping and bricolage within the entrepreneurial process.

  17. The Advantages of Fixed Facilities in Characterizing TRU Wastes

    International Nuclear Information System (INIS)

    FRENCH, M.S.

    2000-01-01

    In May 1998 the Hanford Site started developing a program for characterization of transuranic (TRU) waste for shipment to the Waste Isolation Pilot Plant (WIPP) in New Mexico. After less than two years, Hanford will have a program certified by the Carlsbad Area Office (CAO). By picking a simple waste stream, taking advantage of lessons learned at the other sites, as well as communicating effectively with the CAO, Hanford was able to achieve certification in record time. This effort was further simplified by having a centralized program centered on the Waste Receiving and Processing (WRAP) Facility that contains most of the equipment required to characterize TRU waste. The use of fixed facilities for the characterization of TRU waste at sites with a long-term clean-up mission can be cost effective for several reasons. These include the ability to control the environment in which sensitive instrumentation is required to operate and ensuring that calibrations and maintenance activities are scheduled and performed as an operating routine. Other factors contributing to cost effectiveness include providing approved procedures and facilities for handling hazardous materials and anticipated contingencies and performing essential evolutions, and regulating and smoothing the work load and environmental conditions to provide maximal efficiency and productivity. Another advantage is the ability to efficiently provide characterization services to other sites in the Department of Energy (DOE) Complex that do not have the same capabilities. The Waste Receiving and Processing (WRAP) Facility is a state-of-the-art facility designed to consolidate the operations necessary to inspect, process and ship waste to facilitate verification of contents for certification to established waste acceptance criteria. The WRAP facility inspects, characterizes, treats, and certifies transuranic (TRU), low-level and mixed waste at the Hanford Site in Washington state. Fluor Hanford operates the $89

    Remote video consultations between clinician and patient are technically possible and increasingly acceptable. They are being introduced in some settings alongside (and occasionally replacing) face-to-face or telephone consultations. To explore the advantages and limitations of video consultations, we will conduct in-depth qualitative studies of real consultations (microlevel) embedded in an organisational case study (mesolevel), taking account of national context (macrolevel). The study is based in 2 contrasting clinical settings (diabetes and cancer) in a National Health Service (NHS) acute trust in London, UK. Main data sources are: microlevel--audio, video and screen capture to produce rich multimodal data on 45 remote consultations; mesolevel--interviews, ethnographic observations and analysis of documents within the trust; macrolevel--key informant interviews of national-level stakeholders and document analysis. Data will be analysed and synthesised using a sociotechnical framework developed from structuration theory. City Road and Hampstead NHS Research Ethics Committee, 9 December 2014, reference 14/LO/1883. We plan outputs for 5 main audiences: (1) academics: research publications and conference presentations; (2) service providers: standard operating procedures, provisional operational guidance and key safety issues; (3) professional bodies and defence societies: summary of relevant findings to inform guidance to members; (4) policymakers: summary of key findings; (5) patients and carers: 'what to expect in your virtual consultation'. The research literature on video consultations is sparse. Such consultations offer potential advantages to patients (who are spared the cost and inconvenience of travel) and the healthcare system (eg, they may be more cost-effective), but fears have been expressed that they may be clinically risky and/or less acceptable to patients or staff, and they bring significant technical, logistical and regulatory challenges.

    This lecture presents the experimental techniques, developed in the last 10 or 15 years, in order to perform a new class of experiments with exotic nuclei, where the reactions induced by these nuclei allow to get information on their structure. A brief review of the secondary beams production methods will be given, with some examples of facilities in operation or under project. The important developments performed recently on cryogenic targets will be presented. The different detection systems will be reviewed, both the beam detectors before the targets, and the many kind of detectors necessary to detect all outgoing particles after the reaction: magnetic spectrometer for the heavy fragment, detection systems for the target recoil nucleus, {gamma} detectors. Finally, several typical examples of experiments will be detailed, in order to illustrate the use of each detector either alone, or in coincidence with others. (author)

    In this article, the applications, potential advantages, and challenges of thermal plasma spray (PS) processing for nanopowder production and cell fabrication of solid oxide fuel cells (SOFCs) are reviewed. PS processing creates sufficiently high temperatures to melt all materials fed into the plasma. The heated material can either be quenched into oxide powders or deposited as coatings. This technique has been applied to directly deposit functional layers as well as nanopowder for SOFCs application. In particularly, low melting point and highly active electrodes can be directly fabricated on zirconia-based electrolytes. This is a simple processing technique that does not require the use of organic solvents, offering the opportunity for flexible adjustment of process parameters, and significant time saving in production of the cell and cost reduction compared with tape casting, screen printing and sintering processing steps. Most importantly, PS processing shows strong potential to enable the deposition of metal-supported SOFCs through the integrated fabrication of membrane-electrode assemblies (MEA) on porous metallic substrates with consecutive deposition steps. On the other hand, the application of PS processing to produce SOFCs faces some challenges, such as insufficient porosity of the electrodes, the difficulty of obtaining a thin (<10 {mu}m) and dense electrolyte layer. Fed with H{sub 2} as the fuel gas and oxygen as the oxidant gas, the plasma sprayed cell reached high power densities of 770 mW cm{sup -2} at 900 C and 430 mW cm{sup -2} at 800 C at a cell voltage of 0.7 V.

  1. Principles and advantages of robotics in urologic surgery.

    Renda, Antonio; Vallancien, Guy

    2003-04-01

    Although the available minimally invasive surgical techniques (ie, laparoscopy) have clear advantages, these procedures continue to cause problems for patients. Surgical tools are limited by set axes of movement, restricting the degree of freedom available to the surgeon. In addition, depth perception is lost with the use of two-dimensional viewing systems. As surgeons view a "virtual" target on a television screen, they are hampered by decreased sensory input and a concurrent loss of dexterity. The development of robotic assistance systems in recent years could be the key to overcoming these difficulties. Using robotic systems, surgeons can experience a more natural and ergonomic surgical "feel." Surgical assistance, dexterity and precision enhancement, systems networking, and image-guided therapy are among the benefits offered by surgical robots. In return, the surgeon gains a shorter learning curve, reduced fatigue, and the opportunity to perform complex procedures that would be difficult using conventional laparoscopy. With the development of image-guided technology, robotic systems will become useful tools for surgical training and simulation. Remote surgery is not a routine procedure, but several teams are working on this and experiencing good results. However, economic concerns are the major drawbacks of these systems; before remote surgery becomes routinely feasible, the clinical benefits must be balanced with high investment and running costs.

    We evaluated clinical advantages and the quantitativeness of computerized three-dimensional (3D) cinematic images of a human heart, which were produced with a set of magnetic resonance (MR) images by using the computer graphic technique. Many contiguous, multi-location and multi-phase short axis images were obtained with the ECG gated conventional and fast cardiac imaging sequences in normal volunteers and selected patients with myocardial infarction, hypertrophic cardiomyopathy, dilated cardiomyopathy and left ventricular dysfunction. Judging by visual impressions of the computerized 3D cinematic cardiac images, we could easily understand and evaluate the myocardial motions or the anatomic and volumetric changes of a heart according to the cardiac phases. These images were especially useful to compare the wall motion, the left ventricular ejection-fraction (LVEF), or other cardiac functions and conditions between before and after therapeutic procedures such as percutaneous transluminal coronary angioplasty for patients with myocardial infarction. A good correlation between the LVEF calculated from a set of computerized 3D cinematic images and the ultra sound examinations were found. The results of our study showed that computerized 3D cinematic cardiac images were clinically useful to understand the myocardial motions qualitatively and to evaluate cardiac functions such as the LVEF quantitatively.

    2017-10-01

    The aim of this review was to summarize the advantages and pitfalls of the available osteoporotic animal models of bone healing. A thorough literature search was performed in MEDLINE via OVID and EMBASE to identify animal studies investigating the effect of experimental osteoporosis on bone healing and bone regeneration. The osteotomy model in the proximal tibia is the most popular osseous defect model to study the bone healing process in osteoporotic-like conditions, although other well-characterized models, such as the post-extraction model, might be taken into consideration by future studies. The regenerative potential of osteoporotic bone and its response to biomaterials/regenerative techniques has not been clarified yet, and the critical size defect model might be an appropriate tool to serve this purpose. Since an ideal animal model for simulating osteoporosis does not exist, the type of bone remodeling, the animal lifespan, the age of peak bone mass, and the economic and ethical implications should be considered in our selection process. Furthermore, the influence of animal species, sex, age, and strain on the outcome measurement should be taken into account. In order to make future studies meaningful, standardized international guidelines for osteoporotic animal models of bone healing need to be set up.

  4. [Conclusions. The precautionary principle: its advantages and risks].

    Science.gov (United States)

    Tubiana, M

    2000-01-01

    The proposed extension to health of the precautionary principle is the reaction to two social demands: the desire for greater health safety and for more transparency in the decision making process by associating the public. In medical care, all decisions are based on the balance between cost (dangers induced by the treatment) and benefit (the therapeutic effect). It is as dangerous to overestimate the cost, in other words the risks, as it is to underestimate them. The same problem is encountered in public health. If a vaccination is to be prescribed, the beneficial effects must outweigh the risks; however, these risks are inevitable and have been known to exist since the 18th century, but they have been accepted for the public good. It takes courage to make a vaccination mandatory because those who benefit from it will never know, while those who suffer from its ill effects could take legal action. In order to counter accusations, an evaluation must be made beforehand of the risks and benefits, which underlines the important role of expert opinion. Within the framework of the precautionary principle, actions cannot be taken in ignorance and, at the very least, plausible estimations must be made. The analysis of several recent events (contaminated blood, BSE, growth hormone and Creutzfeldt-Jacob disease) shows that the precautionary principle would have had a very limited impact and that only once there was sufficient knowledge was action made possible. The same is true concerning current debates (the possible risks associated with electromagnetic fields, mobile phones and radon); in these three cases, no country in the world has invoked the precautionary principle, but rather the priority has been given to research. The public understands quite readily the cost/benefit relationship. In the case of oral contraceptives, or hormone replacement therapy the public was aware of their possible health risks but judged that the advantages outweighed the risks. The

    Spin-echo (SE) imaging of lymphadenopathy has been limited by the high signal of surrounding fat. With short TI Inversion Recovery (STIR), fat is cancelled (black), T1 and T2 contrast are additive, and pathologic nodes are white. STIR images (repetition time, 1,400 - 2,400; echo time, 36 or 40; inversion time, 100 or 125) of 69 patients with malignant adenopathy were compared with T1-weighted spin-echo (T1 SE) or intermediate SE and some T2 SE sequences at 0.15 T. Signal-intensity measurements of nodes versus adjacent tissues were used as a measure of contrast. Ratios of these values ranged from 2.5- to more than 17-fold greater for STIR versus T1 or intermediate SE sequences and to more than 40:1 for STIR versus T2 SE images. Some nodes detected on STIR were only identifiable in retrospection CT or T1 SE. In two cases, STIR detected minimally enlarged nodes not detected on CT; biopsy confirmed malignancy. Normal nodes have lower signal than malignant nodes; inflammatory nodes may mimic neoplasm. The authors replaced T2 SE with a combination of T1 SE and STIR, shortening imaging time and enhancing detection of lymphadenopathy

  9. Coarse-grid-CFD. An advantageous alternative to subchannel analysis

    International Nuclear Information System (INIS)

    Class, A.G.; Himmel, S.R.; Viellieber, M.O.

    2011-01-01

    In the 1960 th to 80 th when current GEN II reactor technology was developed, the only possible approach was to use one-dimensional subchannel analysis to compute the flow inside a fuel bundle so that the subchannel scale could be resolved. For simulations of the whole reactor core either system codes or homogenization were employed. In system codes resolution of individual assemblies was the state of the art. Homogenization used porous media equations simulations and averaged the thermohydraulics on reactor core scale. Current potent computing power allows using Computational Fluid Dynamics (CFD) to simulate individual fuel assemblies. Yet the large number of fuel assemblies within the core forbids exploiting CFD for core wide simulation. We propose to combine ideas of subchannel analysis and CFD to develop a new methodology which takes advantage of the fast development of commercial CFD software and the efficiency of subchannel analysis. In this methodology was first applied to simulate a wire-wrap fuel bundle of the High Performance Light Water Reactor (HPLWR). Computations using an inviscid Euler solver on an extremely coarse grid were tuned to predict the true thermohydraulics by adding volumetric forces. These forces represent the non-resolved sub-grid physics. The volumetric forces cannot be measured directly. However, they can be accessed from detailed CFD simulations resolving all relevant physics. Parameterization of these subgrid forces can be realized analogous to models in subchannel codes. In the present work we extend the methodology to the open source solver OpenFOAM and a specific hexagonal fuel assembly which is studied in the framework of liquid metal cooled GEN IV reactor concepts.

    2014-09-01

    Over the past few years, the expansion of general-purpose graphic-processing unit (GPGPU) technology has had a great impact on computational science. GPGPU is the utilization of a graphics-processing unit (GPU) to perform calculations in applications usually handled by the central processing unit (CPU). Use of GPGPUs as a way to increase computational power in the material sciences has significantly decreased computational costs in already highly demanding calculations. A level of the acceleration and parallelization depends on the problem itself. Some problems can benefit from GPU acceleration and parallelization, such as the finite-difference time-domain algorithm (FTDT) and density-functional theory (DFT), while others cannot take advantage of these modern technologies. A number of GPU-supported applications had emerged in the past several years (www.nvidia.com/object/gpu-applications.html). Quantum Espresso (QE) is reported as an integrated suite of open source computer codes for electronic-structure calculations and materials modeling at the nano-scale. It is based on DFT, the use of a plane-waves basis and a pseudopotential approach. Since the QE 5.0 version, it has been implemented as a plug-in component for standard QE packages that allows exploiting the capabilities of Nvidia GPU graphic cards (www.qe-forge.org/gf/proj). In this study, we have examined the impact of the usage of GPU acceleration and parallelization on the numerical performance of DFT calculations. Graphene has been attracting attention worldwide and has already shown some remarkable properties. We have studied an intercalated graphene, using the QE package PHonon, which employs GPU.

    2016-04-01

    Full Text Available Purpose: Culture plays a role in international trade much as it does in any other human activity. Attitudes and ways of life do matter even when a lucrative business opportunity exists, especially across national borders. This paper examines which aspects of culture give countries competitive edge in terms of bilateral trade performances. Specifically, do relatively higher scores in certain cultural dimensions have a deterministic effect on bilateral trade performance (terms of trade or bilateral trade balance? Methodology: We adopt empirical econometric estimation methods on trade data covering 59 countries and 29 years combined with the nine "Global Leadership and Organizational Behavior Effectiveness (GLOBE" culture dimensions, Our estimations were based on Robust Regression Analysis and Ordinary Least Squares methods. Findings: We find that indeed, certain aspects of culture enhance bilateral trade performance/competitiveness. Performance Orientation, Future Orientation, Institutional Collectivism, Gender Egalitarianism, Power Distance and Uncertainty Avoidance improve bilateral trade performance while Assertiveness, Humane Orientation and In-Group Collectivism impair it. Research limitations: Direct measures of international competitiveness are not readily available. So we had to adopt proxies for measuring international competitiveness. Implications: Many countries want to boost international competitiveness. However, in the current world order with multilateral trade agreements under the WTO and increased transferability of technology, governments are clipped in terms of available trade policy options. By understanding which aspects of culture promote bilateral competitiveness and performance, governments could take steps to maximize their competitiveness. For instance, when negotiating trade treaties, policy makers may benefit from the knowledge of culture's impact on competitive advantage when selecting partners. Originality/value: To

    Full Text Available http://dx.doi.org/10.5007/2177-7055.2015v36n71p43 A long-standing consensus exists that the arbitrary or excessive expropriation of private property by a country hurts its economic growth. Although constitutions can play an important role in protecting private property, remarkably little is known about how they actually restrict the power of eminent domain and whether such restrictions are associated with reduced de facto expropriation risks. The main finding of this essay is that no observable relationship exists between de jure constitutional restrictions on the power of eminent domain and de facto expropriation risks. This finding suggests that the effectiveness of takings clauses might depend on the politics surrounding their adoption.

    1997-01-01

    The growing contract energy management business in the United Kingdom is examined. At the top end, established electricity generators are supplying combined heat and power plants of over 20MW or so to meet the steam, power and heating requirements of large industrial sites on contracts of, typically, 15-20 years. These are very much the province of companies such as National Power and PowerGen familiar with linking into the high voltage transmission system and hence able to sell surplus power from these projects into the National Grid. A much wider range of services is on offer by other more specialised companies. These range from the supply and operation of combined heat and power plants to smaller companies, to fuel purchasing contracts and the monitoring of energy consumption of existing facilities in public buildings. Cost cutting is the driving attraction of contract energy management for the purchasers, but there are other advantages. The view of one company, for example, is that it enables them to focus on their core business while leaving energy production and management to a third party whose core business that is. Energy costs become totally forecastable and expertise is always at hand. (UK)

    A variety of research targets in marine sciences including the investigation of gas hydrates, slope stability, alteration of oceanic crust, ore formation and palaeoclimate can be addressed by shallow drilling. However, drill ships are mostly used for deep drillings, both because the effort of building up a drill string from a drill ship to the deep sea floor is tremendous and control on drill bit pressure from a movable platform and a vibrating drill string is poor especially in the upper hundred meters. During the last decade a variety of remotely operated drill rigs have been developed, that are deployed on the sea bed and operated from standard research vessels. These developments include the BMS (Bentic Multicoring System, developed by Williamson and Associates, operated by the Japanese Mining Agency), the PROD (Portable Remotely Operated Drill, developed and operated by Benthic Geotech), the Rockdrill 2 (developed and operated by the British geological Survey) and the MeBo (German abbreviation for sea floor drill rig, developed and operated by Marum, University of Bremen). These drill rigs reach drilling depths between 15 and 100 m. For shallow drillings remotely operated drill rigs are a cost effective alternative to the services of drill ships and have the major advantage that the drilling operations are performed from a stable platform independent of any ship movements due to waves, wind or currents. Sea floor drill rigs can be deployed both in shallow waters and the deep sea. A careful site survey is required before deploying the sea floor drill rig. Slope gradient, small scale topography and soil strength are important factors when planning the deployment. The choice of drill bits and core catcher depend on the expected geology. The required drill tools are stored on one or two magazines on the drill rig. The MeBo is the only remotely operated drill rig world wide that can use wire line coring technique. This method is much faster than conventional

    Few data are available regarding patients' perceptions of new cholecystectomy (CC) techniques, in the context of the patients' risk behaviours. We investigated patients' preferences for transgastric pure natural orifice translumenal endoscopic surgery (NOTES; transgastric NCC) and rigid-hybrid transvaginal NOTES CC (tvNCC) compared with the standard laparoscopic CC (SL-CC), and patients' risk behaviours. A total of 140 inpatients scheduled for elective laparoscopic CC were enrolled in this prospective single-centre study, from January 2009 to January 2010. Patients judged the potential advantages and disadvantages of transgastric NCC and tvNCC compared with SL-CC. The individual's risk behaviour was analysed by means of the validated 40-item Domain-Specific Risk Attitude Scale (DOSPERT). Of the 140 recruited patients, 57 (65% females; mean age 51.5 years) were analysed. Twenty-five percent of males opted for transgastric NCC and 75% opted for SL-CC. Among females, 10.8%, 37.8% and 51.4% opted for transgastric NCC, tvNCC and SL-CC, respectively. Faster convalescence was graded as the primary potential advantage of transgastric NCC, whereas the potential risk of long-term stomach injuries was considered a primary disadvantage. Females graded the reduction of hospital-acquired morbidity as the primary advantage of tvNCC. The risk assessment showed significantly more risk-taking behaviour in the recreational domain of life among patients who opted for innovative surgical techniques than among those opting for conventional surgery. Transgastric NCC is rarely accepted by females but accepted by a quarter of males. Females consider rigid-hybrid tvNCC and SL-CC similarly attractive. Despite promising new techniques, three-quarters of male and one half of female patients still prefer the standard laparoscopic CC.

    Leak detection systems range from simple, visual line walking and checking ones to complex arrangements of hard-ware and software.

    Circadian clocks are believed to confer an advantage to plants, but the nature of that advantage has been unknown. We show that a substantial photosynthetic advantage is conferred by correct matching of the circadian clock period with that of the external light-dark cycle. In wild type and in long- and short-circadian period mutants of Arabidopsis thaliana, plants with a clock period matched to the environment contain more chlorophyll, fix more carbon, grow faster, and survive better than plants with circadian periods differing from their environment. This explains why plants gain advantage from circadian control.

    CERN Multimedia

    2014-01-01

    The 2014 High School Teacher Programme (HST) is well under way, and this year it has a distinct Middle Eastern flavour, with eight teachers from the region among the 54 taking part.   Established in the late 1990s, HST is a three-week residential programme in English designed to give teachers a taste of frontier research and promote the teaching of modern physics in high schools. Along with the more than 30 other teacher schools given in the native language of the participants, HST aims to help teachers bring modern physics to the classroom and motivate their students to study science at upper secondary school and university. As part of the HST programme, teachers form working groups to develop lessons based on CERN science. This year, however, with eight teachers coming from Israel, Palestine, Iran and Jordan, all of which are members of SESAME, the international laboratory for Synchrotron-Light for Experimental Science Applications in the Middle East, one group is working on a dif...

    This session is intended to apprise one of the various aspects of procedures and routines that Exxon Nuclear uses with respect to its nuclear materials physical inventory program. The presentation describes how plant physical inventories are planned and taken. The description includes the planning and preparation for taking the inventory, the clean-out procedures for converting in-process material to measurable items, the administrative procedures for establishing independent inventory teams and for inventorying each inventory area, the verification procedures used to include previously measured tamper-safed items in the inventory, and lastly, procedures used to reconcile the inventory and calculate MUF (materials unaccounted for). The purpose of the session is to enable participants to: (1) understand the planning and pre-inventorty procedures and their importance; (2) understand the need for and the required intensity of clean-out procedures; (3) understand how inventory teams are formed, and how the inventory is conducted; (4) understand the distinction between inventory previously measured tamper-safed items and other materials not so characterized; (5) understand the reconciliation procedures; and (6) calculate a MUF given the book and inventory results

    Rotenberg, E.; Denlinger, J.D.; Kevan, S.D.

    1997-01-01

    Angle-resolved photoemission (ARP) of valence bands is a mature technique that has achieved spectacular success in band-mapping metals, semiconductors, and insulators. The purpose of the present study was the development of experimental and analytical techniques in ARP which take advantage of third generation light sources. Here the authors studied the relatively simple Cu surface in preparation for other metals. Copper and related metals themselves are of current interest, especially due to its role as an interlayer in spin valves and other magnetic heterostructures. A major goal of this study was the development of a systematic technique to quickly (i.e. in a few hours of synchrotron beamtime) measure the FS and separate it into bulk and surface FS's. Often, one needs to avoid bulk features altogether, which one can achieve by carefully mapping their locations in k-space. The authors will also show how they systematically map Fermi surfaces throughout large volumes of k-space, and, by processing the resulting volume data sets, provide intuitive pictures of FS's, both bulk and surface

  16. Home advantage in the Winter Olympics (1908-1998).

    Science.gov (United States)

    Balmer, N J; Nevill, A M; Williams, A M

    2001-02-01

    We obtained indices of home advantage, based on the medals won by competing nations, for each event held at the Winter Olympics from 1908 to 1998. These indices were designed to assess home advantage while controlling for nation strength, changes in the number of medals on offer and the performance of 'non-hosting' nations. Some evidence of home advantage was found in figure skating, freestyle skiing, ski jumping, alpine skiing and short track speed skating. In contrast, little or no home advantage was observed in ice hockey, Nordic combined, Nordic skiing, bobsled, luge, biathlon or speed skating. When all events were combined, a significant home advantage was observed (P = 0.029), although no significant differences in the extent of home advantage were found between events (P > 0.05). When events were grouped according to whether they were subjectively assessed by judges, significantly greater home advantage was observed in the subjectively assessed events (P = 0.037). This was a reflection of better home performances, suggesting that judges were scoring home competitors disproportionately higher than away competitors. Familiarity with local conditions was shown to have some effect, particularly in alpine skiing, although the bobsled and luge showed little or no advantage over other events. Regression analysis showed that the number of time zones and direction of travel produced no discernible trends or differences in performance.

    2017-01-01

    There is a limited amount of home advantage research concerned with winter sports. There is also a distinct lack of studies that investigate home advantage in the context of para sport events. This paper addresses this gap in the knowledge by examining home advantage in the Winter Paralympic Games. Using a standardised measure of success, we compared the performances of host nations at home with their own performances away from home between 1976 and 2014. Both country level and individual sport level analysis is conducted for this time period. Comparisons are also drawn with the Winter Olympic Games since 1992, the point from which both the Winter Olympic Games and the Winter Paralympic Games have been hosted by the same nations and in the same years. Clear evidence of a home advantage effect in the Winter Paralympic Games was found at country level. When examining individual sports, only alpine skiing and cross country skiing returned a significant home advantage effect. When comparing home advantage in the Winter Paralympic Games with the Winter Olympic Games for the last seven host nations (1992-2014), we found that home advantage was generally more pronounced (although not a statistically significant difference) in the case of the former. The causes of home advantage in the Winter Paralympic Games are unclear and should be investigated further.

    2013-03-01

    Giant pituitary adenomas (> 4 cm in maximum diameter) represent a significant surgical challenge. Endoscopic endonasal surgery (EES) has recently been introduced as a treatment option for these tumors. The authors present the results of EES for giant adenomas and analyze the advantages and limitations of this technique. The authors retrospectively reviewed the medical files and imaging studies of 54 patients with giant pituitary adenomas who underwent EES and studied the factors affecting surgical outcome. Preoperative visual impairment was present in 45 patients (83%) and partial or complete pituitary deficiency in 28 cases (52%), and 7 patients (13%) presented with apoplexy. Near-total resection (> 90%) was achieved in 36 patients (66.7%). Vision was improved or normalized in 36 cases (80%) and worsened in 2 cases due to apoplexy of residual tumor. Significant factors that limited the degree of resection were a multilobular configuration of the adenoma (p = 0.002) and extension to the middle fossa (p = 0.045). Cavernous sinus invasion, tumor size, and intraventricular or posterior fossa extension did not influence the surgical outcome. Complications included apoplexy of residual adenoma (3.7%), permanent diabetes insipidus (9.6%), new pituitary insufficiency (16.7%), and CSF leak (16.7%, which was reduced to 7.4% in recent years). Fourteen patients underwent radiation therapy after EES for residual mass or, in a later stage, for recurrence, and 10 with functional pituitary adenomas received medical treatment. During a mean follow-up of 37.9 months (range 1-114 months), 7 patients were reoperated on for tumor recurrence. Three patients were lost to follow-up. Endoscopic endonasal surgery provides effective initial management of giant pituitary adenomas with favorable results compared with traditional microscopic transsphenoidal and transcranial approaches.

    Full Text Available The main objective that business organisations in particular should strive to attain is achieving a competitive advantage position relative to their competitors.. This research empirically examined the importance of and emphasis placed on organisational resources, capabilities and systems in their relationships with competitive advantage. The overall findings indicated significant, positive effects of organisational resources, capabilities and systems collectively on competitive advantage, providing support and corroboration to the resource-based view (RBV. The total variance in competitive advantage accounted for by the multiple linear regression (MLR model was 56.2%. In short, the findings from this study have not only contributed to the literature on the issue of the relationship between organisational resources, capabilities, systems and competitive advantage, but also provided vital information to both practitioners and policy makers on the subject matter.

    2017-01-01

    This study uses several bibliometric indices to explore the temporal course of publication trends regarding the bilingual advantage in executive control over a ten-year window. These indices include the number of published papers, numbers of citations, and the journal impact factor. According to the information available in their abstracts, studies were classified into one of four categories: supporting, ambiguous towards, not mentioning, or challenging the bilingual advantage. Results show that the number of papers challenging the bilingual advantage increased notably in 2014 and 2015. Both the average impact factor and the accumulated citations as of June 2016 were equivalent between categories. However, of the studies published in 2014, those that challenge the bilingual advantage accumulated more citations in June 2016 than those supporting it. Our findings offer evidence-based bibliometric information about the current state of the literature and suggest a change in publication trends regarding the literature on the bilingual advantage.

    Patel, Disha; Bauman, Joseph D; Arnold, Eddy

    2014-01-01

    X-ray crystallography has been an under-appreciated screening tool for fragment-based drug discovery due to the perception of low throughput and technical difficulty. Investigators in industry and academia have overcome these challenges by taking advantage of key factors that contribute to a successful crystallographic screening campaign. Efficient cocktail design and soaking methodologies have evolved to maximize throughput while minimizing false positives/negatives. In addition, technical improvements at synchrotron beamlines have dramatically increased data collection rates thus enabling screening on a timescale comparable to other techniques. The combination of available resources and efficient experimental design has resulted in many successful crystallographic screening campaigns. The three-dimensional crystal structure of the bound fragment complexed to its target, a direct result of the screening effort, enables structure-based drug design while revealing insights regarding protein dynamics and function not readily obtained through other experimental approaches. Furthermore, this "chemical interrogation" of the target protein crystals can lead to the identification of useful reagents for improving diffraction resolution or compound solubility.

    In order to take full advantage of the long time series collected by the GONG and MDI helioseismic projects, we present here an adaptation of the rotation-corrected m-averaged spectrum technique in order to observe low radial-order solar p modes. Modeled profiles of the solar rotation demonstrated the potential advantage of such a technique. Here we develop a new analysis procedure which finds the best estimates of the shift of each m of a given (n, {iota}) multiplet, commonly expressed as an expansion in a set of orthogonal polynomials, which yield the narrowest mode in the m-averaged spectrum. We apply the technique to the GONG data for modes with 1 {<=} {iota} {<=} 25 and show that it allows us to measure lower-frequency modes than with classic peak-fitting analysis of the individual-m spectra.

    2015-04-01

    Happy facial expressions are recognized faster and more accurately than other expressions in categorization tasks, whereas detection in visual search tasks is widely believed to be faster for angry than happy faces. We used meta-analytic techniques for resolving this categorization versus detection advantage discrepancy for positive versus negative facial expressions. Effect sizes were computed on the basis of the r statistic for a total of 34 recognition studies with 3,561 participants and 37 visual search studies with 2,455 participants, yielding a total of 41 effect sizes for recognition accuracy, 25 for recognition speed, and 125 for visual search speed. Random effects meta-analysis was conducted to estimate effect sizes at population level. For recognition tasks, an advantage in recognition accuracy and speed for happy expressions was found for all stimulus types. In contrast, for visual search tasks, moderator analysis revealed that a happy face detection advantage was restricted to photographic faces, whereas a clear angry face advantage was found for schematic and "smiley" faces. Robust detection advantage for nonhappy faces was observed even when stimulus emotionality was distorted by inversion or rearrangement of the facial features, suggesting that visual features primarily drive the search. We conclude that the recognition advantage for happy faces is a genuine phenomenon related to processing of facial expression category and affective valence. In contrast, detection advantages toward either happy (photographic stimuli) or nonhappy (schematic) faces is contingent on visual stimulus features rather than facial expression, and may not involve categorical or affective processing.

    It was almost a decade ago that accelerator experts were introduced to the concept of object-oriented programming. This new methodology was expected to play a key role in solving various software problems. Today, there seems be nothing that prevents us from taking advantage of this new technology. In fact, we are often forced to catch up with the computer industry's new standards. This is especially true for graphics programming. While evaluating the benefits of using this new technology, we must also evaluate whether it is as effective as it was claimed.

    Full Text Available Introduction. Competitive advantage determines the success of modern enterprises, such as hospitality companies, on the market. In turn, competitive advantage is gained as the result of skillful management, taking into account the factors that characterize the company environment. In the management process, methods and concepts that, when properly applied, facilitate the company's innovative activities play the key role, thus contributing to building competitive advantage. The purpose of this paper is to specify and characterize the methods and management concepts most commonly used by hospitality companies in the process of building competitive advantage. The core benefit of these considerations is that they serve to identify those activities of hospitality companies in which the analyzed methods and concepts found practical application. The final part of the article is devoted to an attempt to identify barriers and problems that significantly limit the use of these methods and concepts. Material and methods. In order to achieve this objective, a survey and interviews were carried out in all three- and four-star hotels in the Rzeszów area in the first quarter of 2012. Results. The results revealed that the concept most commonly used by hoteliers was knowledge-based organization (knowledge management, followed by outsourcing, benchmarking and internal competition, respectively. Conclusions. The study also demonstrated that the managers of these hospitality companies significantly lacked substantive knowledge of emerging “market” management methods and concepts.

  19. Does being female provide a neuroprotective advantage following spinal cord injury?

    Directory of Open Access Journals (Sweden)

    Jeffrey P Datto

    2015-01-01

    Full Text Available It has been controversial whether gender has any effect on recovery following spinal cord injury (SCI. Past experimental and clinical research aimed at addressing this subject has led to constrasting findings on whether females hold any advantage in locomotor recovery. Additionally, for studies supporting the notion of a female gender related advantage, a definite cause has not been explained. In a recent study, using large sample sizes for comparative male and female spinal cord injury cohorts, we reported that a significant gender advantage favoring females existed in both tissue preservation and functional recovery after taking into consideration discrepancies in age and weight of the animals across sexes. Prior animal research frequently used sample sizes that were too small to determine significance with certainty and also did not account for two other factors that influence locomotor performance: age and weight. Our finding is important in light of controversy surrounding the effect of gender on outcome and the fact that SCI affects more than ten thousand new individuals annually, a population that is disproportionately male. By deepening our understanding of why a gender advantage exists, potential new therapeutics can be designed to improve recovery for the male population following the initial trauma or putatively augment the neuroprotective privilege in females for enhanced outcomes.
