    Full Text Available The presence and load of species of LAB at the end of the malolactic fermentation (MLF were investigated in 16 wineries from the different Chilean valleys (Limarí, Casablanca, Maipo, Rapel, and Maule Valleys during 2012 and 2013, using PCR-RFLP and qPCR. Oenococcus oeni was observed in 80% of the samples collected. Dominance of O. oeni was reflected in the bacterial load (O. oeni/total bacteria measured by qPCR, corresponding to >85% in most of the samples. A total of 178 LAB isolates were identified after sequencing molecular markers, 95 of them corresponded to O. oeni. Further genetic analyses were performed using MLST (7 genes including 10 commercial strains; the results indicated that commercial strains were grouped together, while autochthonous strains distributed among different genetic clusters. To pre-select some autochthonous O. oeni, these isolates were also characterized based on technological tests such as ethanol tolerance (12 and 15%, SO2 resistance (0 and 80 mg l−1, and pH (3.1 and 3.6 and malic acid transformation (1.5 and 4 g l−1. For comparison purposes, commercial strain VP41 was also tested. Based on their technological performance, only 3 isolates were selected for further examination (genome analysis and they were able to reduce malic acid concentration, to grow at low pH 3.1, 15% ethanol and 80 mg l−1 SO2. The genome analyses of three selected isolates were examined and compared to PSU-1 and VP41 strains to study their potential contribution to the organoleptic properties of the final product. The presence and homology of genes potentially related to aromatic profile were compared among those strains. The results indicated high conservation of malolactic enzyme (>99% and the absence of some genes related to odor such as phenolic acid decarboxylase, in autochthonous strains. Genomic analysis also revealed that these strains shared 470 genes with VP41 and PSU-1 and that autochthonous strains harbor an interesting

    2018-02-09

    The convergence of different theories (ie, catch-up effect and windows of opportunities) allows for the interpretation of different "technological innovation gaps" in Chile's biomedical industry. It is common knowledge that Chile has always had an economy almost exclusively based on services, commodities, and mainly in the exploitation of natural resources with low value added. The literature confirms that countries that concentrate their economies on the knowledge, research, development, and commercialization of technology and innovation have a better and more stable growth rate in the medium and long run. The "Asian Tigers" are a good example of this. Analyzing the technological gaps that affect the Chilean biomedical industry, it is possible to find windows of opportunities to catch up. This could allow the country to take its knowledge, skills, and capabilities further, thus enabling Chile to not just depend on its unpredictable natural resources. For the first time, a quantitative diagnosis of the Chilean biomedical industry was made. This study considered the Chilean biomedical industry and its innovation and entrepreneurship environment, taking into account its productive capacities and its potential to make progress in technological innovation and, as a result, dramatically reducing technological gaps through windows of opportunities.

    Iron deficiency is the most prevalent nutritional deficiency in the world, primarily affecting infants, young children, and women of childbearing age. To evaluate the impact of the National Complementary Feeding Program (NCFP) on anemia and iron status in Chilean children aged 11 to 18 months. Two studies were performed. The first study was performed at one public outpatient health center in Santiago, using data collected in 1999 (n = 128) and 2000 (n = 125), before and after the national introduction of iron-fortified milk. Subsequently, a study of a representative sample (n = 320) from the two most populated areas of the country was performed in 2009. One year after fortification, the prevalence of anemia was 9%; significantly lower (p < .001) than the 27% prevalence observed 1 year before. Ten years after fortification, 14% of children were anemic and 77% of children with anemia (12% of all children) suffered from iron-deficiency anemia. In 2009, 11% of children consuming iron-fortified milk delivered by the NCFP (73%) were anemic, significantly lower (p = .028) than the 21% prevalence of anemia observed in children without consumption. Consumption of iron-fortified milk was positively associated with hemoglobin concentration (r = 0.28, p = .022) and was associated with a lower prevalence of anemia after adjusting for confounding factors (odds ratio, 0.50; 95% CI, 0.26 to 0.96). In Chile, the NCFP has had an impact on the reduction of anemia and improved the iron status of children aged 11 to 18 months. Increasing the consumption of this iron-fortified milk could enhance the impact of the NCFP.

    Analysis of potential utilization of applicable SO 2 -removal process for reduced-SO 2 -strength off-gases, including electron-beam irradiation, for incrementally improving overall abatement of SO 2 /SO 3 emissions from existing copper smelting facilities in Chile has been carried out. Off-gases are characterized by SO 2 content higher than 3,000 ppm, a complex chemical composition and highly oxidizing conditions, along with cyclical and fluctuating generation, reflecting relatively severe service. Laboratory tests with simulated high-SO 2 -strength process gas were performed at Polish Institute of Nuclear Chemistry and Technology. Test work proved the technical feasibility of removing SO 2 from ultra-high SO 2 content smelter gases by E-beam irradiation with ammonia injection. A laboratory unit with flow rate of 20 Nm 3 /h equipped with electron accelerator of 800 keV beam energy was used. Influence of different parameters on SO 2 removal efficiency, like temperature, dose, ammonia stoichiometry and water vapor content, has been established. Tests covered a high SO 2 content range, 2,000 to 10,000 ppm. A generic design has been deviced to address system arrangement, performance and control requirements. It encompasses upgrading of in-plant ventilation to the extent required by health standards, together with gas cleaning system based on EB Process. The arrangement of the facilities provides for gathering and treating off-gas from selected fugitive emission sources on a continuous basis, at the same time in-drafting a minimum amount of tramp air. An introductory dry dedusting stage uses activated coke injection in conjunction with a fabric filter to efficiently treat raw gas to remove heavy metals, including arsenic, along with particulate matter. Main conclusion of the two major stages of this work, i.e. experimental tests and engineering oriented studies, is that the EB Process is a simple and appropriate, cost-effective, chemical process that would, on a site

    2011-01-01

    Stroke survivors with hemiparesis and spinal cord injury (SCI) survivors with tetraplegia find it difficult or impossible to perform many activities of daily life. There is growing evidence that intensive exercise therapy, especially when supplemented with functional electrical stimulation (FES), can improve upper extremity function, but delivering the treatment can be costly, particularly after recipients leave rehabilitation facilities. Recently, there has been a growing level of interest among researchers and healthcare policymakers to deliver upper extremity treatments to people in their homes using in-home teletherapy (IHT). The few studies that have been carried out so far have encountered a variety of logistical and technical problems, not least the difficulty of conducting properly controlled and blinded protocols that satisfy the requirements of high-level evidence-based research. In most cases, the equipment and communications technology were not designed for individuals with upper extremity disability. It is clear that exercise therapy combined with interventions such as FES, supervised over the Internet, will soon be adopted worldwide in one form or another. Therefore it is timely that researchers, clinicians, and healthcare planners interested in assessing IHT be aware of the pros and cons of the new technology and the factors involved in designing appropriate studies of it. It is crucial to understand the technical barriers, the role of telesupervisors, the motor improvements that participants can reasonably expect and the process of optimizing IHT-exercise therapy protocols to maximize the benefits of the emerging technology.

    Pyrosequencing technology is a rather novel DNA sequencing method based on the sequencing-by-synthesis principle. This bioluminometric, real-time DNA sequencing technique employs a cascade of four enzymatic reactions producing sequence peak signals. The method has been proven highly suitable for single nucleotide polymorphism analysis and sequencing of short stretches of DNA. Although the pyrosequencing procedure is relatively straightforward, users may face challenges due to varying parameters in PCR and sequencing primer design, sample preparation and nucleotide dispensation; such challenges are labor and cost intensive. In this study, these issues have been addressed to increase signal quality and assure sequence accuracy. PMID:16530870

    The simplification of genetic selection to the pragmatic choice of an appropriate base population, together with the adoption of such techniques as multiple ovulation and embryo transfer to accelerate the rate of response within the chosen population, would increase the contribution of genetic methods to the improvement of the performance of domestic animals. This is particularly relevant to developing countries where limited funds may constrain the opportunities for husbandry improvement, where it is important to select animals under the local conditions and where the infrastructure might limit the use of extensive programmes such as those based on progeny testing.

    Oral health education/promotion interventions have been identified as cost-efficient tools to improve the oral health of the population. These interventions are regularly made in contexts where the target population is captive, for example, in health centres. In Chile, there are no oral health interventions delivered at home. This community trial covers two disadvantaged urban areas in the province of Concepción. Both sectors have public preschool education coverage with a traditional programme (TP) to promote oral health. The intervention will comprise four to six visits by dental hygienists trained in the delivery of a standardised oral health promotion programme using motivational interviewing (MI) at home. The experimental group will receive TP and MI, while the control group will receive only TP. If a positive and significant effect of MI is found, this will be administered to the control group. For a 50% reduction in the incidence of caries, a sample size of 120 preschoolers per group is estimated. Data will be gathered on demographic and socioeconomic variables; oral health outcomes using WHO oral health indicators (the prevalence and severity of caries, periodontal disease, dentofacial anomalies and oral hygiene); the oral health literacy of caregivers, measured by the Rapid Estimation of Adult Literacy in Dentistry and the Oral Health Literacy Instrument, both validated for the Chilean population. Assessments will take place at baseline and at 12-month follow-up. The university bioethics committee approved this study (EI/21/2014). We will submit the trial's results for presentation at international scientific meetings and to peer-reviewed journals.

  19. Improving Technology for Vascular Imaging

    Science.gov (United States)

    Rana, Raman

    Neuro-endovascular image guided interventions (Neuro-EIGIs) is a minimally invasive procedure that require micro catheters and endovascular devices be inserted into the vasculature via an incision near the femoral artery and guided under low dose fluoroscopy to the vasculature of the head and neck. However, the endovascular devices used for the purpose are of very small size (stents are of the order of 50mum to 100mum) and the success of these EIGIs depends a lot on the accurate placement of these devices. In order to accurately place these devices inside the patient, the interventionalist should be able to see them clearly. Hence, high resolution capabilities are of immense importance in neuro-EIGIs. The high-resolution detectors, MAF-CCD and MAF-CMOS, at the Toshiba Stroke and Vascular Research Center at the University at Buffalo are capable of presenting improved images for better patient care. Focal spot of an x-ray tube plays an important role in performance of these high resolution detectors. The finite size of the focal spot results into the blurriness around the edges of the image of the object resulting in reduced spatial resolution. Hence, knowledge of accurate size of the focal spot of the x-ray tube is very essential for the evaluation of the total system performance. Importance of magnification and image detector blur deconvolution was demonstrated to carry out the more accurate measurement of x-ray focal spot using a pinhole camera. A 30 micron pinhole was used to obtain the focal spot images using flat panel detector (FPD) and different source to image distances (SIDs) were used to achieve different magnifications (3.16, 2.66 and 2.16). These focal spot images were deconvolved with a 2-D modulation transfer function (MTF), obtained using noise response (NR) method, to remove the detector blur present in the images. Using these corrected images, the accurate size of all the three focal spots were obtained and it was also established that effect of

    Non-adherence to prescribed treatment is a principle cause of treatment failure in patients with chronic diseases, such as type 2 diabetes mellitus (T2DM) and hypertension. Improved patient monitoring and education have been shown to improve adherence and clinical outcomes. This study evaluates the impact of a pharmacotherapy optimization plan centered on patient education that was implemented at a hospital in Arauco, Chile. A prospective study was conducted using 50 randomly selected patients diagnosed with both T2DM and hypertension. Each patient participated in three successive interview sessions over 6 months. At each session, the following variables were evaluated by a pharmacist: blood pressure, HbA1c, adherence to prescribed medication, and patient knowledge of disease. Significant decreases were observed for HbA1c (<0.001), and SBP (<0.001), with stronger and more significant decreases observed for females. Patient adherence to prescribed medication also improved, but not significantly. The number of patients with full knowledge of their diseases increased significantly (p < 0.001) from 10 to 66%. This study suggests that the incorporation of a pharmacotherapeutic optimization plan for patients with chronic diseases can have a positive impact on the control of chronic diseases, such as T2DM and hypertension.

  1. Technology in Arthroplasty: Are We Improving Value?

    Waddell, Bradford S; Carroll, Kaitlin; Jerabek, Seth

    2017-09-01

    Total joint arthroplasty is regarded as a highly successful procedure. Patient outcomes and implant longevity, however, are related to proper alignment and position of the prostehses. In an attempt to reduce outliers and improve accuracy and precision of component position, navigation and robotics have been introduced. These technologies, however, come at a price. The goals of this review are to evaluate these technologies in total joint arthroplasty and determine if they add value. Recent studies have demonstrated that navigation and robotics in total joint arthroplasty can decrease outliers while improving accuracy in component positioning. While some studies have demonstrated improved patient reported outcomes, not all studies have shown this to be true. Most studies cite increased cost of equipment and longer operating room times as the major downsides of the technologies at present. Long-term studies are just becoming available and are promising, as some studies have shown decreased revision rates when navigation is used. Finally, there are relatively few studies evaluating the direct cost and value of these technologies. Navigation and robotics have been shown to improve component position in total joint arthroplasty, which can improve patient outcomes and implant longevity. These technologies offer a promising future for total joint arthroplasty.

    Full Text Available Purpose. The volume of cargo transportation demands the introduction of a new generation of cars that would be able to provide all the needs of carriers. But this is impossible without the implementation of renovation repair facilities with the introduction of new technologies and modernization of the repair process. Repair of rolling stock is a key factor that must proceed with the establishment of new cars, as not all of the inventions may be repaired in car-repair depots, most of which are obsolete. The purpose is to analyze the possibility of increasing the efficiency of the repair process by introducing new repair technologies or improving the existing ones. It will improve not only the quality of the repair, but also its rate. Methodology. Works on improving the designs of freight cars are held by many design organizations in almost all industrialized countries. It makes repair organizations (depots and car-repair plants to upgrade the repair process. Achievements of-this goal is possible by improving the technology renovation and reorganization through the use of flexible flow technologies, which to date are the most effective in the repair of rolling stock. Findings. When performing the analysis it was determined that there are different designs of cars. More of cars are all-purpose and their repair does not cause difficulties for car-repair business. However, the number of specialized cars is also significant, and the technology of their repair should be improved. One of the reasons is that many models, such as tank wagons for the carriage of sulfur, are intended for the carriage of dangerous goods and their failure at the time of motion is not permitted. Originality. Firstly the authors have defined direction at improving technologies of repair specialized cars. Practical value. Actual improvement in the construction of cars is to improve the existing repair facilities. In addition, the repair technology using nowadays when repairing

  8. Improvements in SPECT technology for cerebral imaging

    International Nuclear Information System (INIS)

    Esser, P.D.

    1985-01-01

    Advancement in three major areas of SPECT (single photon emission computed tomography) technology have resulted in improved image quality for cerebral studies. In the first area, single-crystal camera electronics, extensive use of microprocessors, custom digital circuitry, an data bus architecture have allowed precise external control of all gantry motions and improved signal processing. The new digital circuitry permits energy, uniformity, and linearity corrections to be an integral part of the processing electronics. Calibration of these correlations is controlled by algorithms stored in the camera's memory. The second area of improved SPECT technology is camera collimation and related imaging techniques. In this area, system resolution has been improved without loss of sensitivity by decreasing the air gap between patient and collimator surface. Since cerebral studies characteristically image high-contrast regions less than 1 cm in size, image quality has been improved by increasing collimator resolution even at the expense of sensitivity. Increased resolution also improved image contrast for studies using 123 I-labeled pharmaceuticals with 3% to 4% 124 I contamination. 65 references

    Effective irrigant delivery and agitation are prerequisites to promote root canal disinfection and debris removal and improve successful endodontic treatment. This paper presents an overview of the currently available technologies to improve the cleaning of the endodontic space and their debridement efficacy. A PubMed electronic search was conducted with appropriate key words to identify the relevant literature on this topic. After retrieving the full-text articles, all the articles were reviewed and the most appropriate were included in this review. Several different systems of mechanical activation of irrigants to improve endodontic disinfection were analysed: manual agitation with gutta-percha cones, endodontic instruments or special brushes, vibrating systems activated by low-speed hand-pieces or by sonic or subsonic energy, use of ultrasonic or laser energy to mechanically activate the irrigants and apical negative pressure irrigation systems. Furthermore, this review aims to describe systems designed to improve the intracanal bacterial decontamination by a specific chemical action, such as ozone, direct laser action or light-activated disinfection. The ultrasonic activation of root canal irrigants and of sodium hypochlorite in particular still remains the gold standard to which all other systems of mechanical agitation analyzed in this article were compared. From this overview, it is evident that the use of different irrigation systems can provide several advantages in the clinical endodontic outcome and that integration of new technologies, coupled with enhanced techniques and materials, may help everyday clinical practice.

    This describes work done in the final phase of a 3-y, 3-phase contract to demonstrate cost reductions and improvements in manufacturing technology. The work focused on near-term projects in the SSI (Siemens Solar Industries) Czochralski (Cz) manufacturing facility in Camarillo, CA; the final phase was concentrated in areas of crystal growth, wafer technology, and environmental, safety, and health issues. During this period: (1) The crystal-growing operation improved with increased growth capacity; (2) Wafer processing with wire saws continued to progress; the wire saws yielded almost 50 percent more wafers per inch in production. The wire saws needs less etching, too; (3) Cell processing improvements focused on better handling and higher mechanical yield. The cell electrical distribution improved with a smaller standard deviation in the distribution; and (4) Module designs for lower material and labor costs continued, with focus on a new junction box, larger modules with larger cells, and less costly framing techniques. Two modules demonstrating these cost reductions were delivered during this phase.

    Full Text Available Knowledge management (KM is a key element for the development of small-to-medium enterprises (SMEs in the construction industry. This is particularly relevant in Chile, where this industry is composed almost entirely of SMEs. Although various KM system proposals can be found in the literature, they are not suitable for SMEs, due to usability problems, budget constraints, and time and connectivity issues. Mobile Cloud Computing (MCC systems offer several advantages to construction SMEs, but they have not yet been exploited to address KM needs. Therefore, this research is aimed at the development of a MCC-based KM platform to manage lessons learned in different construction projects of SMEs, through an iterative and user-centered methodology. Usability and quality evaluations of the proposed platform show that MCC is a feasible and attractive option to address the KM issues in SMEs of the Chilean construction industry, since it is possible to consider both technical and usability requirements.

  13. Results of Chilean water markets: Empirical research since 1990

    Bauer, Carl J.

    2004-09-01

    Chile's free-market Water Code turned 20 years old in October 2001. This anniversary was an important milestone for both Chilean and international debates about water policy because Chile has become the world's leading example of the free-market approach to water law and water resources management, the textbook case of treating water rights not merely as private property but also as a fully marketable commodity. The predominant view outside of Chile is that Chilean water markets and the Chilean model of water management have been a success, and this perception has encouraged other countries to follow Chile's lead in water law reform. Much of the debate about Chilean water markets, however, has been based more on theoretical or political beliefs than on empirical study. This paper reverses that emphasis by reviewing the evolution of empirical research about these markets since 1990, when Chile returned to democratic government after 16 years of military rule. During the period since 1990, understanding of how Chilean water markets have worked in practice has gradually improved. There have been two major trends in this research: first, a gradual shift from exaggerated claims of the markets' success toward more balanced assessments of mixed results and, second, a heavy emphasis on the economics of water rights trading with very little attention given to the Water Code's impacts on social equity, river basin management, environmental protection, or resolution of water conflicts. The analysis in this study is qualitative and interdisciplinary, combining law, economics, and institutions.

    2008-01-01

    Socio-cultural factors and HIV-related misinformation contribute to the increasing number of Chilean women living with HIV. In spite of this, and to date, few culturally specific prevention activities have been developed for this population. The goal of the present study was to elicit the perspectives of low-income Chilean women regarding HIV and relevant socio-cultural factors, as a forerunner to the development of a culturally appropriate intervention. As part of a mixed-methods study, fifty low-income Chilean women participated in a survey and twenty were selected to participate in prevention, in-depth interviews. Results show evidence of widespread misinformation and misconceptions related to HIV/AIDS. Machismo and marianismo offer major barriers to prevention programme development. Future HIV prevention should stress partner communication, empowerment and improving the education of women vulnerable to HIV. PMID:18432428

  16. Review of Thermal Materials for CSP Plants and LCOE Evaluation for Performance Improvement using Chilean Strategic Minerals: Lithium Salts and Copper Foams

    Directory of Open Access Journals (Sweden)

    Gustavo Cáceres

    2016-01-01

    Full Text Available The improvement of solar thermal technologies in emerging economies like Chile is particularly attractive because the country is endowed with one of the most consistently high solar potentials, lithium and copper reserves. In recent years, growing interests for lithium based salts and copper foams in application of thermal technologies could change the landscape of Chile transforming its lithium reserves and copper availability into competitive energy produced in the region. This study reviews the technical advantages of using lithium based salts—applied as heat storage media and heat transfer fluid—and copper foam/Phase Change Materials (PCM alternatives—applied as heat storage media—within tower and parabolic trough Concentrated Solar Power (CSP plants, and presents a first systematic evaluation of the costs of these alternatives based on real plant data. The methodology applied is based on material data base compilation of price and technical properties, selection of CSP plant and estimation of amount of required material, and analysis of Levelized Cost of Electricity (LCOE. Results confirm that some lithium based salts are effective in reducing the amount of required material and costs for the Thermal Energy Storage (TES systems for both plant cases, with savings of up to 68% and 4.14% in tons of salts and LCOE, respectively. Copper foam/PCM composites significantly increase thermal conductivity, decreasing the volume of the TES system, but costs of implementation are still higher than traditional options.

    As the Hitachi Group's efforts in nuclear power generation, this paper explains the safety improvement technologies that are currently under development or promotion. As efforts for the decommissioning of Fukushima Daiichi Nuclear Power Station, the following items have been developed. (1) As for the spent fuel removal of Unit 4, the following items have mainly been conducted: removal of the debris piled up on the top surface of existing reactor building (R/B), removal of the debris deposited in spent fuel pool (SFP), and fuel transfer operation by means of remote underwater work. The removal of all spent fuels was completed in 2014. (2) The survey robots inside R/B, which are composed of a basement survey robot to check leaking spots at upper pressure suppression chamber and a floor running robot to check leaking spots in water, were verified with a field demonstration test at Unit 1. These robots were able to find the leaking spots at midair pipe expansion joint. (3) As the survey robot for reactor containment shells, robots of I-letter posture and horizontal U-letter posture were developed, and the survey on the upper part of first-floor grating inside the containment shells was performed. (4) As the facilities for contaminated water measures, sub-drain purification equipment, Advanced Liquid Processing System, etc. were developed and supplied, which are now showing good performance. On the other hand, an advanced boiling water reactor with high safety of the United Kingdom (UK ABWR) is under procedure of approval for introduction. In addition, a next-generation light-water reactor of transuranic element combustion type is under development. (A.O.)

  19. Improving Information Technology Curriculum Learning Outcomes

    The case study research methodology has been selected to conduct the inquiry into this phenomenon. This empirical inquiry facilitates exploration of a contemporary phenomenon in depth within its real-life context using a variety of data sources. The subject of analysis will be two Information Technology classes composed of a combination of second year and third year students; both classes have six students, the same six students. Contribution It is the purpose of this research to show that the use of improved approaches to learning will produce more desirable learning outcomes. Findings The results of this inquiry clearly show that the use of the traditional behaviorist based pedagogic model to achieve college and university IT program learning outcomes is not as effective as a more constructivist based andragogic model. Recommendations Instruction based purely on either of these does a disservice to the typical college and university level learner. The correct approach lies somewhere in between them; the most successful outcome attainment would be the product of incorporating the best of both. Impact on Society Instructional strategies produce learning outcomes; learning outcomes demonstrate what knowledge has been acquired. Acquired knowledge is used by students as they pursue professional careers and other ventures in life. Future Research Learning and teaching approaches are not “one-size-fits-all” propositions; different strategies are appropriate for different circumstances and situations. Additional research should seek to introduce vehicles that will move learners away from one the traditional methodology that has been used throughout much of their educational careers to an approach that is better suited to equip them with the skills necessary to meet the challenges awaiting them in the professional world.

  8. Opportunities to integrate solar technologies into the Chilean lithium mining industry - reducing process related GHG emissions of a strategic storage resource

    Telsnig, Thomas; Potz, Christian; Haas, Jannik; Eltrop, Ludger; Palma-Behnke, Rodrigo

    2017-06-01

    The arid northern regions of Chile are characterized by an intensive mineral mining industry and high solar irradiance levels. Besides Chile's main mining products, copper, molybdenum and iron, the production of lithium carbonate from lithium containing brines has become strategically important due to the rising demand for battery technologies worldwide. Its energy-intensive production may affect the ecological footprint of the product and the country's climate targets. Thus, the use of solar technologies for electricity and heat production might constitute an interesting option for CO2 mitigation. This study aims to quantify the impacts of the lithium carbonate production processes in Chile on climate change, and to identify site-specific integration options of solar energy technologies to reduce GHG life-cycle emissions. The considered solar integration options include a parabolic trough power plant with a molten salt storage, a solar tower power plant with molten salt receiver and molten salt storage, a one-axis tracking photovoltaic energy system for electricity, and two solar thermal power plants with Ruths storage (steam accumulator) for thermal heat production. CSP plants were identified as measures with the highest GHG mitigation potential reducing the CO2 emissions for the entire production chain and the lithium production between 16% and 33%. In a scenario that combines solar technologies for electricity and thermal energy generation, up to 59% of the CO2 emissions at the lithium production sites in Chile can be avoided. A comparison of the GHG abatement costs of the proposed solar integration options indicates that the photovoltaic system, the solar thermal plant with limited storage and the solar tower power plant are the most cost effective options.

  9. Blockchain technology for improving clinical research quality.

    Benchoufi, Mehdi; Ravaud, Philippe

    2017-07-19

    Reproducibility, data sharing, personal data privacy concerns and patient enrolment in clinical trials are huge medical challenges for contemporary clinical research. A new technology, Blockchain, may be a key to addressing these challenges and should draw the attention of the whole clinical research community.Blockchain brings the Internet to its definitive decentralisation goal. The core principle of Blockchain is that any service relying on trusted third parties can be built in a transparent, decentralised, secure "trustless" manner at the top of the Blockchain (in fact, there is trust, but it is hardcoded in the Blockchain protocol via a complex cryptographic algorithm). Therefore, users have a high degree of control over and autonomy and trust of the data and its integrity. Blockchain allows for reaching a substantial level of historicity and inviolability of data for the whole document flow in a clinical trial. Hence, it ensures traceability, prevents a posteriori reconstruction and allows for securely automating the clinical trial through what are called Smart Contracts. At the same time, the technology ensures fine-grained control of the data, its security and its shareable parameters, for a single patient or group of patients or clinical trial stakeholders.In this commentary article, we explore the core functionalities of Blockchain applied to clinical trials and we illustrate concretely its general principle in the context of consent to a trial protocol. Trying to figure out the potential impact of Blockchain implementations in the setting of clinical trials will shed new light on how modern clinical trial methods could evolve and benefit from Blockchain technologies in order to tackle the aforementioned challenges.

    delegation, it was clear that a multidisciplinary approach was required to properly analyze the emergency response, technical, and social components of this disaster. A diverse and knowledgeable delegation was necessary to analyze the Chilean response in a way that would be beneficial to preparedness in California, as well as improve mitigation efforts around the United States. By most standards, the Maule earthquake was a catastrophe for Chile. The economic losses totaled $30 billion USD or 17% of the GDP of the country. Twelve million people, or ¾ of the population of the country, were in areas that felt strong shaking. Yet only 521 fatalities have been confirmed, with 56 people still missing and presumed dead in the tsunami. The Science and Technology Team evaluated the impacts of the earthquake on built environment with implications for the United States. The fires following the earthquake were minimal in part because of the shutdown of the national electrical grid early in the shaking. Only five engineer-designed buildings were destroyed during the earthquake; however, over 350,000 housing units were destroyed. Chile has a law that holds building owners liable for the first 10 years of a building’s existence for any losses resulting from inadequate application of the building code during construction. This law was cited by many our team met with as a prime reason for the strong performance of the built environment. Overall, this earthquake demonstrated that strict building codes and standards could greatly reduce losses in even the largest earthquakes. In the immediate response to the earthquake and tsunami, first responders, emergency personnel, and search and rescue teams handled many challenges. Loss of communications was significant; many lives were lost and effective coordination to support life-sustaining efforts was gravely impacted due to a lack of inter- and intra-agency coordination.

    Buckner, M.A.

    1993-02-01

    Providing accurate neutron dosimetry for a variety of neutron energy spectra is a formidable task for any dosimetry system. Unless something is known about the neutron spectrum prior to processing the dosimeter, the calculated dose may vary greatly from that actually encountered; that is until now. The entrance of bubble detector technology into the field of neutron dosimetry has eliminated the necessity of having an a priori knowledge of the neutron energy spectra. Recently, a new approach in measuring personnel neutron dose equivalent was developed at Oak Ridge National Laboratory. By using bubble detectors in combination with current thermoluminescent dosimeters (TLDs) as a Combination Personnel Neutron Dosimeter (CPND), not only is it possible to provide accurate dose equivalent results, but a simple four-interval neutron energy spectrum is obtained as well. The components of the CPND are a Harshaw albedo TLD and two bubble detectors with theoretical energy thresholds of 100 key and 1500 keV. Presented are (1) a synoptic history surrounding emergence of bubble detector technology, (2) a brief overview of the current theory on mechanisms of interaction, (3) the data and analysis process involved in refining the response functions, (4) performance evaluation of the original CPND and a reevaluation of the same data under the modified method, (5) the procedure used to determine the reference values of component fluence and dose equivalent for field assessment, (6) analysis of the after-modification results, (7) a critique of some currently held assumptions, offering some alternative explanations, and (8) thoughts concerning potential applications and directions for future research

    Rodrigues, Licinia O; Alves, Teresa P; Cardoso, Joaquim P; Menezes, José C

    2006-01-01

    Within the process analytical technology (PAT) framework, as presented in the US Food and Drug Administration guidelines, the aim is to design, develop and operate processes consistently to ensure a pre-defined level of quality at the end of the manufacturing process. Three PAT implementation scenarios can be envisaged. Firstly, PAT could be used in its most modest version (in an almost non-PAT manner) to simply replace an existing quality control protocol (eg, using near-infrared spectroscopy for an in-process quality control, such as moisture content). Secondly, the use of in-process monitoring and process analysis could be integrated to enhance process understanding and operation for an existing industrial process. Thirdly, PAT could be used extensively and exclusively throughout development, scale-up and full-scale production of a new product and process. Although the first type of implementations are well known, reports of the second and third types remain scarce. Herein, results obtained from PAT implementations of the second and third types are described for two industrial processes for preparing bulk active pharmaceutical ingredients, demonstrating the benefits in terms of increased process understanding and process control.

  19. Improving Neural Recording Technology at the Nanoscale

    Ferguson, John Eric

    Neural recording electrodes are widely used to study normal brain function (e.g., learning, memory, and sensation) and abnormal brain function (e.g., epilepsy, addiction, and depression) and to interface with the nervous system for neuroprosthetics. With a deep understanding of the electrode interface at the nanoscale and the use of novel nanofabrication processes, neural recording electrodes can be designed that surpass previous limits and enable new applications. In this thesis, I will discuss three projects. In the first project, we created an ultralow-impedance electrode coating by controlling the nanoscale texture of electrode surfaces. In the second project, we developed a novel nanowire electrode for long-term intracellular recordings. In the third project, we created a means of wirelessly communicating with ultra-miniature, implantable neural recording devices. The techniques developed for these projects offer significant improvements in the quality of neural recordings. They can also open the door to new types of experiments and medical devices, which can lead to a better understanding of the brain and can enable novel and improved tools for clinical applications.

    Full Text Available Period of Pinochet rule in Chile is still in the centre of interest of many experts. This article concentrates (mostly on the economic side of the military rule. Pinochet took responsibility for the country in situation near to economic collapse caused by policy of the previous – Allendeęs government. The new government after the coup dęétat in 1973 had to stabilize economy. Soldiers at the same time start to implement economic reforms that improved the long run ability of the economy to grow. The economic uplift was interrupted by debt crisis at the beginning of 1980s. Pinochetęs government was able to deal with these obstacles and at the end passed the economy to the democratic government (at the end of 1980s in good shape. The following positive development in the 1990s is thus based on the foundations built under the military rule.

  13. Quantitative Determination of Technological Improvement from Patent Data

    Science.gov (United States)

    2015-01-01

    The results in this paper establish that information contained in patents in a technological domain is strongly correlated with the rate of technological progress in that domain. The importance of patents in a domain, the recency of patents in a domain and the immediacy of patents in a domain are all strongly correlated with increases in the rate of performance improvement in the domain of interest. A patent metric that combines both importance and immediacy is not only highly correlated (r = 0.76, p = 2.6*10-6) with the performance improvement rate but the correlation is also very robust to domain selection and appears to have good predictive power for more than ten years into the future. Linear regressions with all three causal concepts indicate realistic value in practical use to estimate the important performance improvement rate of a technological domain. PMID:25874447

    1999-01-01

    In summary, major paradigm shifts in the health care industry are altering the way technology is maintained and supported. Service organizations are now responsible for maintaining a broader base of technology within the health care delivery network and must to this on an extremely rapid, efficient, and productive basis. A number of new technologies are coming on-line, which can allow a health care technology service organization to experience significant improvements in profitability, efficiency, and productivity. To realize maximum benefit from these technologies, service organizations may find themselves re-engineering their service processes. The author believes that this is a requirement for many service organizations, regardless of whether new technology is implemented. The traditional approaches to service delivery are ineffective in managing the new structural realities and service requirements of today's health care environment. New strategies and tactics are required for ensuring that these requirements are met. These approaches will no doubt improve the overall quality, productivity, and efficiency of service and are based on best practices utilized by leading OEMs and ISOs in the medical electronics and other high technology service industry such as information technology and telecommunications, where the service organization is responsible for supporting a broad array of the technology over a large geography with a densely populated installed base, not unlike the typical health care delivery service environment. Once operational improvements are made, a service organization can take advantage of the productivity and efficiency gains brought on by new technology. Organizations interested in doing so are urged to thoroughly research the current state-of-the-art and best practices, because there are numerous systems currently available off-the-shelf. The author believes that new technology will be a basic requirement for competing in the health care

    2018-02-01

    Full Text Available Operational Risk Management (ORM comprises the continuous management of risks resulting from: human actions, internal processes, systems, and external events. With increasing requirements, complexity and a growing volume of risks, information systems provide benefits for integrating risk management activities and optimizing performance. Business Performance Management (BPM technologies are believed to provide a solution for effective Operational Risk Management by offering several combined technologies including: work flow, data warehousing, (advanced analytics, reporting and dashboards. BPM technologies can be integrated with an organization’s Planning & Control cycle and related to strategic objectives. This manuscript aims to show how ORM can benefit from BPM technologies via the development and practical validation of a new maturity model. The B4ORM maturity model was developed following the Design Science Research approach. The maturity model relates specific maturity levels of ORM processes with BPM technologies applicable for a specific maturity stage. There appears to be a strong relationship (0.78 with ORM process maturity and supporting BPM technologies. The B4ORM maturity model as described in this manuscript provides an ideal path of BPM technologies related to six distinctive stages of ORM, leading towards technologies suitable for continuous improvement of ORM processes and organization-wide integration.

    Cybertherapy is a field that is growing rapidly due to today's technology and information boom. Virtual reality and advanced technologies have been used successfully to in a variety of healthcare issues, including treatment of anxiety disorders and phobias, treatment of eating and body dysmorphic disorders, neuropsychological assessment and rehabilitation and distraction during painful or unpleasant medical procedures. The novel applications of these technologies yield many advantages over traditional treatment modalities, and the disadvantages that accompanied the first trials of virtual reality are quickly being addressed and eliminated. Virtual reality peripherals such as data gloves, physiological monitoring and Internet worlds are swiftly demonstrating their usefulness in cybertherapy applications. Future directions for research include improvements of objective measures of efficacy such as fMRI and physiological monitoring devices, and investigations are being carried out to determine if virtual reality and advanced technologies can be used to treat a broader scope of disorders, including depression, schizophrenia, drug addiction, and autism.

    Animal welfare is receiving increasing attention from the authorities, the public and NGOs. For this reason, the improvement of animal welfare and animal handling systems is of the utmost importance for the meat industry. Technological developments have led to more animal friendly systems that handle animals on the day of slaughter, and these developments will be even more important as consideration for animal welfare and sustainability is no longer just a trend but a licence to operate. Improvement of animal welfare also leads to a higher value of the carcasses due to higher product quality, less cut-off caused by fewer injuries, and reduced working load, which leads to increased business opportunities. Therefore, good animal welfare is good business, and the development and implementation of new technology is the way to obtain improved animal welfare. These subjects will be addressed using examples and cases from the pork and broiler production industry. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Science.gov (United States)

    Cianelli, Rosina; Ferrer, Lilian; McElmurry, Beverly J

    2008-04-01

    Socio-cultural factors and HIV-related misinformation contribute to the increasing number of Chilean women living with HIV. In spite of this, and to date, few culturally specific prevention activities have been developed for this population. The goal of the present study was to elicit the perspectives of low-income Chilean women regarding HIV and relevant socio-cultural factors, as a forerunner to the development of a culturally appropriate intervention. As part of a mixed-methods study, fifty low-income Chilean women participated in a survey and twenty were selected to participate in prevention, in-depth interviews. Results show evidence of widespread misinformation and misconceptions related to HIV/AIDS. Machismo and marianismo offer major barriers to prevention programme development. Future HIV prevention should stress partner communication, empowerment and improving the education of women vulnerable to HIV.

  9. Ecosystem process interactions between central Chilean habitats

    Directory of Open Access Journals (Sweden)

    Meredith Root-Bernstein

    2015-01-01

    Full Text Available Understanding ecosystem processes is vital for developing dynamic adaptive management of human-dominated landscapes. We focus on conservation and management of the central Chilean silvopastoral savanna habitat called “espinal”, which often occurs near matorral, a shrub habitat. Although matorral, espinal and native sclerophyllous forest are linked successionally, they are not jointly managed and conserved. Management goals in “espinal” include increasing woody cover, particularly of the dominant tree Acacia caven, improving herbaceous forage quality, and increasing soil fertility. We asked whether adjacent matorral areas contribute to espinal ecosystem processes related to the three main espinal management goals. We examined input and outcome ecosystem processes related to these goals in matorral and espinal with and without shrub understory. We found that matorral had the largest sets of inputs to ecosystem processes, and espinal with shrub understory had the largest sets of outcomes. Moreover, we found that these outcomes were broadly in the directions preferred by management goals. This supports our prediction that matorral acts as an ecosystem process bank for espinal. We recommend that management plans for landscape resilience consider espinal and matorral as a single landscape cover class that should be maintained as a dynamic mosaic. Joint management of espinal and matorral could create new management and policy opportunities.

Particularly in agriculture, the genetically modified plants have augmented resistance to harmful agents, enhanced product yield, and shown increased adaptability for better survival. Moreover, recombinant pharmaceuticals are now being used confidently and rapidly attaining commercial approvals. Techniques of recombinant DNA technology, gene therapy, and genetic modifications are also widely used for the purpose of bioremediation and treating serious diseases. Due to tremendous advancement and broad range of application in the field of recombinant DNA technology, this review article mainly focuses on its importance and the possible applications in daily life.

  11. Why technology matters as much as science in improving healthcare.

    Science.gov (United States)

    Szczerba, Robert J; Huesch, Marco D

    2012-09-10

    More than half a million new items of biomedical research are generated every year and added to Medline. How successful are we at applying this steady accumulation of scientific knowledge and so improving the practice of medicine in the USA? The conventional wisdom is that the US healthcare system is plagued by serious cost, access, safety and quality weaknesses. A comprehensive solution must involve the better translation of an abundance of clinical research into improved clinical practice.Yet the application of knowledge (i.e. technology) remains far less well funded and less visible than the generation, synthesis and accumulation of knowledge (i.e. science), and the two are only weakly integrated. Worse, technology is often seen merely as an adjunct to practice, e.g. electronic health records.Several key changes are in order. A helpful first step lies in better understanding the distinction between science and technology, and their complementary strengths and limitations. The absolute level of funding for technology development must be increased as well as being more integrated with traditional science-based clinical research. In such a mission-oriented federal funding strategy, the ties between basic science research and applied research would be better emphasized and strengthened. It bears repeating that only by applying the wealth of existing and future scientific knowledge can healthcare delivery and patient care ever show significant improvement.

  12. Improving truck safety: Potential of weigh-in-motion technology

    Directory of Open Access Journals (Sweden)

    2010-07-01

    Full Text Available Trucks exceeding the legal mass limits increase the risk of traffic accidents and damage to the infrastructure. They also result in unfair competition between transport modes and companies. It is therefore important to ensure truck compliance to weight regulation. New technologies are being developed for more efficient overload screening and enforcement. Weigh-in-Motion (WIM technologies allow trucks to be weighed in the traffic flow, without any disruption to operations. Much progress has been made recently to improve and implement WIM systems, which can contribute to safer and more efficient operation of trucks.

  14. Misconception p value among Chilean and Italian academic psychologists

    Directory of Open Access Journals (Sweden)

    Laura Badenes-Ribera

    2016-08-01

    Full Text Available The p value misconceptions are based on certain beliefs and attributions about the significance of the results. Thus, they affect the professionals’ decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italians, 30 Chileans, questioned on this topic. Our findings are consistent with original research and suggest that some participants do not know how to correctly interpret p values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy. These results highlight the importance of the statistical re-education of researchers. Recommendations for improving statistical cognition are proposed.

    Health technology assessment (HTA) is the multidisciplinary study of the implications of the development, diffusion and use of health technologies. It supports health-policy decisions by providing a joint knowledge base for decision-makers. To increase its policy relevance, HTA tries to extend beyond effectiveness and costs to also considering the social, organizational and ethical implications of technologies. However, a commonly accepted method for analysing the ethical aspects of health technologies is lacking. This paper describes a model for ethical analysis of health technology that is easy and flexible to use in different organizational settings and cultures. The model is part of the EUnetHTA project, which focuses on the transferability of HTAs between countries. The EUnetHTA ethics model is based on the insight that the whole HTA process is value laden. It is not sufficient to only analyse the ethical consequences of a technology, but also the ethical issues of the whole HTA process must be considered. Selection of assessment topics, methods and outcomes is essentially a value-laden decision. Health technologies may challenge moral or cultural values and beliefs, and their implementation may also have significant impact on people other than the patient. These are essential considerations for health policy. The ethics model is structured around key ethical questions rather than philosophical theories, to be applicable to different cultures and usable by non-philosophers. Integrating ethical considerations into HTA can improve the relevance of technology assessments for health care and health policy in both developed and developing countries.

  16. MANAGEMENT TECHNOLOGIES AS A MEANS OF IMPROVING MANAGEMENT

    Directory of Open Access Journals (Sweden)

    Komarov V. F.

    2017-09-01

    Full Text Available Scientists and managers pay great attention to improving planning and accounting at the enterprise level. Significantly less attention is paid to issues of theory and methodology of the personal planning and accounting activities of the managers themselves. This reason causes companies to sustain large losses. These losses could be avoided by introducing the company management technology, within which formalized procedures of personal planning and accounting would be implemented. It is necessary to implement the technology specifically. Because only the technology allows you to synchronize and harmonize the individual steps, procedures, operations of a process. Allows you to control the process. Eliminates the concept of «management is an art» or «management is a craft». In favor of the concept of «management is regulated by the procedural process». That allows to avoid dependence on personal qualities and whims of the agents. The technology is based on the principle of decomposing every activity into its component elements. This separation, on the one hand, allows to raise efficiency of implementation of individual stages, procedures, operations. On the other hand, conscious design and implementation of a rational sequence of steps, procedures, and operations give the system effect - increase in the productivity of human activity. In addition, technologies serve as a mediator between science and practice (scientific knowledge is transmitted to the economic and social spheres through technology, and help replicate best practices, promote specialization of human activity (and hence growth of labor productivity. This article investigates the nature and properties of management technologies, the technique of their design, describes the experience of building technology for personal planning and accounting activities of managers and specialists at specific enterprises.

    Weigel, Fred K; Switaj, Timothy L; Hamilton, Jessica

    2015-01-01

    Healthcare delivery in America is extremely complex because it is comprised of a fragmented and nonsystematic mix of stakeholders, components, and processes. Within the US healthcare structure, the federal healthcare system is poised to lead American medicine in leveraging health information technology to improve the quality of healthcare. We posit that through developing, adopting, and refining health information technology, the federal healthcare system has the potential to transform federal healthcare quality by managing the complexities associated with healthcare delivery. Although federal mandates have spurred the widespread use of electronic health records, other beneficial technologies have yet to be adopted in federal healthcare settings. The use of health information technology is fundamental in providing the highest quality, safest healthcare possible. In addition, health information technology is valuable in achieving the Agency for Healthcare Research and Quality's implementation goals. We conducted a comprehensive literature search using the Google Scholar, PubMed, and Cochrane databases to identify an initial list of articles. Through a thorough review of the titles and abstracts, we identified 42 articles as having relevance to health information technology and quality. Through our exclusion criteria of currency of the article, citation frequency, applicability to the federal health system, and quality of research supporting conclusions, we refined the list to 11 references from which we performed our analysis. The literature shows that the use of computerized physician order entry has significantly increased accurate medication dosage and decreased medication errors. The use of clinical decision support systems have significantly increased physician adherence to guidelines, although there is little evidence that indicates any significant correlation to patient outcomes. Research shows that interoperability and usability are continuing challenges for

    2018-04-01

    Full Text Available Table olives are the most widely consumed fermented food in the Mediterranean countries. Peculiar processing technologies are used to process olives, which are aimed at the debittering of the fruits and improvement of their sensory characteristics, ensuring safety of consumption at the same time. Processors demand for novel techniques to improve industrial performances, while consumers' attention for natural and healthy foods has increased in recent years. From field to table, new techniques have been developed to decrease microbial load of potential spoilage microorganisms, improve fermentation kinetics and ensure safety of consumption of the packed products. This review article depicts current technologies and recent advances in the processing technology of table olives. Attention has been paid on pre processing technologies, some of which are still under-researched, expecially physical techniques, such ad ionizing radiations, ultrasounds and electrolyzed water solutions, which are interesting also to ensure pesticide decontamination. The selections and use of starter cultures have been extensively reviewed, particularly the characterization of Lactic Acid Bacteria and Yeasts to fasten and safely drive the fermentation process. The selection and use of probiotic strains to address the request for functional foods has been reported, along with salt reduction strategies to address health concerns, associated with table olives consumption. In this respect, probiotics enriched table olives and strategies to reduce sodium intake are the main topics discussed. New processing technologies and post packaging interventions to extend the shelf life are illustrated, and main findings in modified atmosphere packaging, high pressure processing and biopreservaton applied to table olive, are reported and discussed.

    Most children experience pain in hospitals; and their parents report dissatisfaction with how well pain was managed. Engaging patients and families in the development and evaluation of pain treatment plans may improve perceptions of pain management and hospital experiences. The aim of this performance improvement project was to engage patients and families to address hospitalized pediatric patients' pain using interactive patient care technology. The goal was to stimulate conversations about pain management expectations and perceptions of treatment plan effectiveness among patients, parents, and health care teams. Plan-Do-Study-Act was used to design, develop, test, and pilot new workflows to integrate the interactive patient care technology system with the automated medication dispensing system and document actions from both systems into the electronic health record. The pediatric surgical unit and hematology/oncology unit of a free-standing, university-affiliated, urban children's hospital were selected to pilot this performance improvement project because of the high prevalence of pain from surgeries and hematologic and oncologic diseases, treatments, and invasive procedures. Documentation of pain assessments, nonpharmacologic interventions, and evaluation of treatment effectiveness increased. The proportion of positive family satisfaction responses for pain management significantly increased from fiscal year 2014 to fiscal year 2016 (p = .006). By leveraging interactive patient care technologies, patients and families were engaged to take an active role in pain treatment plans and evaluation of treatment outcomes. Improved active communication and partnership with patients and families can effectively change organizational culture to be more sensitive to patients' pain and patients' and families' hospital experiences.

    Competitiveness of power equipment primarily depends on speeding-up the development and mastering of new equipment samples and technologies, enhancement of organisation and management of design, manufacturing and operation. Actual political, technological and economic conditions cause the acute need in changing the strategy and tactics of process planning. At that the issues of maintenance of equipment with simultaneous improvement of its efficiency and compatibility to domestically produced components are considering. In order to solve these problems, using the systems of computer-aided process planning for process design at all stages of power equipment life cycle is economically viable. Computer-aided process planning is developed for the purpose of improvement of process planning by using mathematical methods and optimisation of design and management processes on the basis of CALS technologies, which allows for simultaneous process design, process planning organisation and management based on mathematical and physical modelling of interrelated design objects and production system. An integration of computer-aided systems providing the interaction of informative and material processes at all stages of product life cycle is proposed as effective solution to the challenges in new equipment design and process planning.

  6. Improving information technology competencies: implications for psychiatric mental health nursing.

    Science.gov (United States)

    Fetter, Marilyn S

    2009-01-01

    While substantial evidence links information technology (IT) with improved patient safety, care quality, access, and efficiency, nurses must demonstrate competencies in computers, informatics, and information literacy in order to use IT for practice, education, and research. The nursing profession has established IT competencies for all nurses at beginning and experienced levels. Newly revised standards also articulate role-specific expectations for advanced practice nurses. Unfortunately, there is a concern that many nurses may not possess these capabilities and that nurse educators are not prepared to teach them. IT competency evaluations, which have focused predominately on nursing education, indicate novice skill levels for most faculty and students. In numerous studies, again conducted largely in nursing education, significant improvement in IT competencies has been achieved only with intensive interventions. Deficits in IT competencies are a significant concern, because the federal government has mandated full implementation of Electronic Health Records (EHR) by 2014. EHR will require all nurses to use IT to deliver, document, and obtain reimbursement for patient care. In response to these concerns, two recent initiatives, the "Health Information Technology Scholars (HITS)" and "Technology Informatics Guiding Education Reform (TIGER)" projects, have been launched. By enhancing IT competencies, these projects will enable nurses to use evidence-based practice and other innovations to transform clinical care, education, and research. This report updates psychiatric-mental health nurses on the IT competencies literature, recent enhancement initiatives and innovations, and their implications for the specialty.

    Childhood obesity is an increasing public health problem in western culture. Sedentary lifestyles and an "obesogenic environment" are the main influences on children leading to an increase in obesity. The objective of this paper is to describe an e-health platform for the treatment and prevention of childhood obesity called ETIOBE. This e-health platform is an e-therapy system for the treatment of obesity, aimed at improving treatment adherence and promoting the mechanisms of self-control in patients, to obtain weight loss maintenance and to prevent relapse by establishing healthy lifestyle habits. ETIOBE is composed of three different applications, the Clinician Support System (CSS), the Home Support System (HSS) and the Mobile Support System (MSS). The use of new Information and Communication (ICT) technologies can help clinicians to improve the effectiveness of weight loss treatments, especially in the case of children, and to achieve designated treatment goals.

  14. IMPROVING LOGISTICS SERVICES THROUGH THE TECHNOLOGY USED IN FLEET MANAGEMENT

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Outsourcing logistics has established itself in the area of the LSP (Logistics Service Provider, which offers a range of services to its customers. In this line, transportation is characterized as one of the most important services, and therefore efficient fleet management is essential for establishing a high level of customer service. With advances in technology and vehicle tracking systems, this approach of management has gained new possibilities for the improvement of logistics services. By studying the specific case of an LSP, this paper investigates the use of these technologies in the management of their business and services. The results indicate that the LSP seeks to increase its services and to streamline information in order to respond to customer needs in real time. It is also evident in this case under study that the combination of the technology available together with the fleet management system has become a distinguishing feature for this LSP, one which increases their skills and important information for both customers and business.

    We present a framework for relativistic quantum metrology that is useful for both Earth-based and space-based technologies. Quantum metrology has been so far successfully applied to design precision instruments such as clocks and sensors which outperform classical devices by exploiting quantum properties. There are advanced plans to implement these and other quantum technologies in space, for instance Space-QUEST and Space Optical Clock projects intend to implement quantum communications and quantum clocks at regimes where relativity starts to kick in. However, typical setups do not take into account the effects of relativity on quantum properties. To include and exploit these effects, we introduce techniques for the application of metrology to quantum field theory. Quantum field theory properly incorporates quantum theory and relativity, in particular, at regimes where space-based experiments take place. This framework allows for high precision estimation of parameters that appear in quantum field theory including proper times and accelerations. Indeed, the techniques can be applied to develop a novel generation of relativistic quantum technologies for gravimeters, clocks and sensors. As an example, we present a high precision device which in principle improves the state-of-the-art in quantum accelerometers by exploiting relativistic effects.

    1998-07-01

    Safety and reliability in glovebox operations can be significantly improved and waste packaging efficiencies can be increased by inserting flexible, lightweight, high capacity HEPA filters into the walls of plastic sheet barriers. This HEPA filter/barrier technology can be adapted to a wide variety of applications: disposable waste bags, protective environmental barriers for electronic equipment, single or multiple use glovebag assemblies, flexible glovebox wall elements, and room partitions. These reliable and inexpensive filtered barriers have many uses in fields such as radioactive waste processing, HVAC filter changeout, vapor or grit blasting, asbestos cleanup, pharmaceutical, medical, biological, and electronic equipment containment. The applications can result in significant cost savings, improved operational reliability and safety, and total waste volume reduction. This technology was developed at the Argonne National Laboratory-West (ANL-W) in 1993 and has been used at ANL-W since then at the TRU Waste Characterization Chamber Gloveboxes. Another 1998 AGS Conference paper titled "TRU Waste Characterization Gloveboxes", presented by Mr. David Duncan of ANL-W, describes these boxes.

    2003-01-01

    Korea Hydro and Nuclear Power (KHNP) has been managed Nuclear Power Plant (NPP) construction projects including basic project planning, design, procurement, construction and start-up for nearly 30 years, and taken the leading role in the self-reliance program for constructing NPP. To maintain its leading position of construction technology and export it to other countries, it is more likely required to build the strong and competitive business management system to improve internal business efficiency and transparency, and also to respond to the change of external business circumstances such as electricity market opening. KHNP is implementing Enterprise Resource Planning (ERP) System as a business innovation tool to improve business efficiency, which changes the way of performing work from organizational system to process-oriented system in order to optimize the company resources to achieve above goals. This change should be made based on the results of performing Business Process Re-engineering (BPR) to maximize overall business efficiency. For the construction project management area, the establishment of Integrated Construction Information Sharing System based on Information Technology (IT) is the most important part. It makes possible to build collaboration system with 'Win-Win strategy' between the project owner and all related entities and to contribute to secure transparency and cut the project cost down. We would like to introduce our NPP Construction Project Management System, Infrastructure for Information System, Information Sharing System among construction related entities and Implementation Practices in this paper and also include the suggestions on our customary practice and subject that should be improved

    Full Text Available Zero tillage technology revealed with no use of any soil inverting technique to grow crops. The crop plant seed is planted in the soil directly after irrigation to make the soil soft without any replenishing in soil layers. A study was conducted to evaluate cotton genotypes FH-114 and FH-142 for the consecutive three years of growing seasons from 2013-15. The seed of both genotypes was sown with two date of sowing, 1 March and 1 May of each three years of sowing under three tillage treatments (zero tillage, minimum tillage and conventional tillage in triplicate completely randomized split-split plot design. It was found from results that significant differences were recorded for tillage treatments, date of sowing, genotypes and their interactions. Multivariate analysis was performed to evaluate the yield and it attributed traits for potential of FH-114 and FH-142 cotton genotypes. The genotype FH-142 was found with higher and batter performance as compared to FH-114 under zero tillage, minimum tillage and conventional tillage techniques. The traits bolls per plant, boll weight, fibre fineness, fibre strength, plant height, cotton yield per plant and sympodial branches per plant were found as most contributing traits towards cotton yield and production. It was also found that FH-142 gives higher output in terms of economic gain under zero tillage with 54% increase as compared to conventional tillage technique. It was suggested that zero tillage technology should be adopted to improve cotton yield and quality. It was also recommended that further study to evaluate zero tillage as potential technology should be performed with different regions, climate and timing throughout the world.

  1. Reforming Technologies to Improve the Performance of Combustion Systems

    Directory of Open Access Journals (Sweden)

    Hashim Hassan

    2014-09-01

    Full Text Available A large number of theoretical and experimental studies have shown that the performance of kerosene combustion increases significantly if combustion is being assisted by the addition of hydrogen to the fuel/air mixture during the combustion process. It reduces the amount of CO, CO2 and NOx emissions, while increasing the flame stability limits. It also helps in bruning fuel/air mixtures at much leaner equivalence ratios. The same principle could be applied to gain benefits in gas turbine combustors. Hydrogen for this purpose could be produced by the reforming of hydrocarbon fuels using a reformer module. This paper presents key hydrogen reforming technologies which, by implementation in gas turbine combustors, hold potential for improving both their performance and service life.

    2008-03-01

    The industrial sector consumes nearly 40% of annual global primary energy use and is responsible for a similar share of global energy-related carbon dioxide (CO2) emissions. Many studies and actual experience indicate that there is considerable potential to reduce the amount of energy used to manufacture most commodities, concurrently reducing CO2 emissions. With the support of strong policies and programs, energy-efficient technologies and measures can be implemented that will reduce global CO2 emissions. A number of countries, including the Netherlands, the UK, and China, have experience implementing aggressive programs to improve energy efficiency and reduce related CO2 emissions from industry. Even so, there is no silver bullet and all options must be pursued if greenhouse gas emissions are to be constrained to the level required to avoid significant negative impacts from global climate change.

    1997-12-01

    Recent advances in drilling rig technologies that improve the ways for finding oil and natural gas, and are also solving some safety and transportation problems, have been reviewed. The coiled tubing drilling rig developed by joint venture TransOcean Ensign Drilling Technology was one of the innovations described. It is able to run a three-and-a-quarter inch coiled tubing, the only system capable of doing this in a land-based application. Tesco Corporation`s new casing drilling rig, which is expected to lower the cost of moving the rig, and Brinkerhoff Drilling`s new generation modular (NGM)-rig, claimed to be the most mobile rig in North America, are other new developments worthy of note. Tesco`s casing drilling rig has the potential to reduce drilling costs by as much as 30 to 40 per cent, while the NGM-rig could reduce rig mobilization time by 50 to 80 per cent, and the number of wells drilled by the same rig could increase by 20 per cent, due to the NGM-rig`s versatility and flexibility.

    Claudia Mellado

    2011-11-01

    Full Text Available On the basis of survey responses of 570 journalists from 114 newspapers, radio, newswires, television, and internet news organizations, this paper describes the role conceptions, epistemological underpinning, and ethical values of the Chilean news media workers, comparing the differences that exist among media types and between the capital and the rest of the country. The findings show territorial cultures of journalism, with differences between the capital and provincial regions, mostly classifiable, because of the country’s centralization and sociocultural characteristics. Likewise, the results indicate that the Chilean journalists’ professional culture is not a substantial function of the type of media in which they work, and that the effects that “region” and “media type” factors have on journalism culture are independent from each other.

    Full Text Available The article reports an exploratory research on the uses given in Chile to the Anglicism bullying. In order to do so, its evolution is reviewed from the early studies in the Nordic countries, to the treatment of the topic in the Chilean context. The focus of this work is based on socioconstructionism and in turn promotes the consideration of the characteristics of the socio-cultural and historical context of knowledge production with a postcolonial intention. To review the constructions on the subject, we selected Chilean videos at the YouTube virtual platform, using as methodology discourse analysis and dense description. In results can be observed two meanings of bullying: (i to refer to any kind of aggression and (ii as a homologous of abuse among schoolchildren. In response, it is realized the discrepancy with the proposed definitions from general academia and those used in the local environment in investigations, interventions, public policy and mass media in Chile.

    2014-01-01

    Full Text Available The agro-industrial sector in developing countriesis faced with challenges, such as requirement for increase of food production and yield and creation of opportunity for employment of rural and poor population. In addition, the agricultural sector is influenced by global factors and fast changes. These facts indicate that there is great need for information and information technologies (IT, which can be used to cope with the challenges and changes and to improve agricultural production and marketing. However, the potential of IT is not fully utilized in agriculture. Implementation of IT in agricultural sector and rural areas is relatively slow in comparison to the other sectors of the economy where contemporary IT has been implemented at high speed. The aim of the paper is to analyze role, potential and contribution of IT in agribusiness and to explain opportunities for use of IT in many fields of agricultural sector. Our findings are based on economic theory and available literature, and they suggest that IT has great potential for supporting farmers and the other stakeholders in improvement of efficiency, effectiveness and productivity of agriculture. However, the stakeholders have to cope with many limitations and problems in IT implementation and use.

    Full Text Available In essence, process of maintaining equipment is a support process, because it indirectly contributes to operational ability of the production process necessary for the supply chain of the new value. Taking into account increased levels of automatization and quality, this proces s becomes more and more significant and for some branches of industry, even crucial. Due to the fact that the quality of the entire process is more and more dependent on the maintenance process, these processes must be carefully designed and effectively im plemented. There are various techniques and approaches at our disposal, such as technical, logistical and intensive application of the information - communication technologies. This last approach is presented in this work. It begins with organizational goa ls, especially quality objectives. Then, maintenance processes and integrated information system structures are defined. Maintenance process quality and improvement processes are defined using a set of performances, with a special emphasis placed on effectiveness and quality economics. At the end of the work, information system for improving maintenance economics is structured. Besides theoretical analysis, work also presents results authors obtained analyzing food industry, metal processing industry an d building materials industry.

    This presentation will emphasize NASA's water research, applications, and capacity building activities using satellites and models to contribute to water issues including water availability, transboundary water, flooding and droughts for improved Integrated Water Resources Management (IWRM). NASA's free and open exchange of Earth data observations and products helps engage and improve integrated observation networks and enables national and multi-national regional water cycle research and applications that are especially useful in data sparse regions of most developing countries. NASA satellite and modeling products provide a huge volume of valuable data extending back over 50 years across a broad range of spatial (local to global) and temporal (hourly to decadal) scales and include many products that are available in near real time (see earthdata.nasa.gov). To further accomplish these objectives NASA works to actively partner with public and private groups (e.g. federal agencies, universities, NGO's, and industry) in the U.S. and international community to ensure the broadest use of its satellites and related information and products and to collaborate with regional end users who know the regions and their needs best. Key objectives of this talk will highlight NASA's Water Resources and Capacity Building Programs with their objective to discover and demonstrate innovative uses and practical benefits of NASA's advanced system technologies for improved water management in national and international applications. The event will help demonstrate the strong partnering and the use of satellite data to provide synoptic and repetitive spatial coverage helping water managers' deal with complex issues. The presentation will also demonstrate how NASA is a major contributor to water tasks and activities in GEOSS (Global Earth Observing System of Systems) and GEO (Group on Earth Observations).

    2009-12-01

    In order to learn about Chilean women's reflections about womanhood and sexuality during midlife, we held focus group discussions (FGDs) with middle-aged Chilean women living in Stockholm, Sweden, or in Santiago, Chile. We used thematic content analysis for the qualitative data. Emerging themes follow; societal expectations on women, perceptions about sexual relationships, and women's social stigmatization. The women had since childhood been strongly influenced by a gender-imbalanced world, which had made them socially, economically, and biologically at higher risk for exploitation during life. More focus should be directed to middle-aged women's life situation and promotion of gender equity in society.

    Strople, Bernadette; Ottani, Patricia

    2006-01-01

    Shift report is a multifaceted process that serves to provide nurses with vital patient information to facilitate clinical decisions and patient care planning. A shift report also provides nurses with a forum for functions, such as patient problem solving and collaboration. The authors conducted a literature review, which indicates that current methodologies used to collect and convey patient information are ineffective and may contribute to negative patient outcomes. Data incongruence, legal implications, time constraints augmented by the nursing shortage, and the financial impact of shift report are also addressed. The literature reveals significant rationale for pioneering new and innovative methods of shift-to-shift communication. In the report To Err is Human: Building a Safe Health System, the Institute of Medicine attributes the deaths of up to 98,000 hospitalized Americans to medical errors, including communication failures [Institute of Medicine. (1999). To err is human: Building a safe health system. Report by the Committee on Quality of Health Care in America. Washington, DC: National Academy Press]. As a result, government policy makers and health care agencies have focused their attention on determining the root cause of errors to identify preventative measures, including the use of information technology [Institute of Medicine. (2004). Keeping patients safe: Transforming the work environment of nurses. Report by the Committee on Quality of Health Care in America. Washington, DC: National Academy Press]. Under these premises, the authors examined the process of nursing shift report and how it impacts patient outcomes. The use of computer technology and wireless modes of communication is explored as a means of improving the shift report process and, subsequently, health care outcomes and patient safety.

    2014-11-01

    The aim of this study was to describe and evaluate an approach for improving radiopharmaceutical supply chain safety by implementing bar code technology. We first evaluated the current situation of our radiopharmaceutical supply chain and, by means of the ALARM protocol, analysed two dispensing errors that occurred in our department. Thereafter, we implemented a bar code system to secure selected key stages of the radiopharmaceutical supply chain. Finally, we evaluated the cost of this implementation, from overtime, to overheads, to additional radiation exposure to workers. An analysis of the events that occurred revealed a lack of identification of prepared or dispensed drugs. Moreover, the evaluation of the current radiopharmaceutical supply chain showed that the dispensation and injection steps needed to be further secured. The bar code system was used to reinforce product identification at three selected key stages: at usable stock entry; at preparation-dispensation; and during administration, allowing to check conformity between the labelling of the delivered product (identity and activity) and the prescription. The extra time needed for all these steps had no impact on the number and successful conduct of examinations. The investment cost was reduced (2600 euros for new material and 30 euros a year for additional supplies) because of pre-existing computing equipment. With regard to the radiation exposure to workers there was an insignificant overexposure for hands with this new organization because of the labelling and scanning processes of radiolabelled preparation vials. Implementation of bar code technology is now an essential part of a global securing approach towards optimum patient management.

    To describe an implementation of one information technology system (electronic medical record, EMR) in one hospital, the perceived impact, the factors thought to help and hinder implementation and the success of the system and compare this with theories of effective IT implementation. To draw on previous research, empirical data from this study is used to develop IT implementation theory. Qualitative case study, replicating the methods and questions of a previously published USA EMR implementation study using semi-structured interviews and documentation. Large Swedish teaching hospital shortly after a merger of two hospital sites. Thirty senior clinicians, managers, project team members, doctors and nurses. The Swedish implementation was achieved within a year and for under half the budget, with a generally popular EMR which was thought to save time and improve the quality of patient care. Evidence from this study and findings from the more problematic USA implementation case suggests that key factors for cost effective implementation and operation were features of the system itself, the implementation process and the conditions under which the implementation was carried out. There is empirical support for the IT implementation theory developed in this study, which provides a sound basis for future research and successful implementation. Successful implementation of an EMR is likely with an intuitive system, requiring little training, already well developed for clinical work but allowing flexibility for development, where clinicians are involved in selection and in modification for their department needs and where a realistic timetable is made using an assessment of the change-capability of the organization. Once a system decision is made, the implementation should be driven by top and departmental leaders assisted by competent project teams involving information technology specialists and users. Corrections for unforeseen eventualities will be needed, especially

    Airborne gravity data has contributed greatly to our knowledge of subsurface geophysics particularly in rugged and otherwise inaccessible areas such as Antarctica. Reliable high quality GPS data has renewed interest in improving the accuracy of airborne gravity systems and recent improvements in the electronic control of the sensor have increased the accuracy and ability of the classic Lacoste and Romberg zero length spring gravity meters to operate in turbulent air conditions. Lacoste and Romberg type gravity meters provide increased sensitivity over other relative gravity meters by utilizing a mass attached to a horizontal beam which is balanced by a ';zero length spring'. This type of dynamic gravity sensor is capable of measuring gravity changes on the order of 0.05 milliGals in laboratory conditions but more commonly 0.7 to 1 milliGal in survey use. The sensor may have errors induced by the electronics used to read the beam position as well as noise induced by unwanted accelerations, commonly turbulence, which moves the beam away from its ideal balance position otherwise known as the reading line. The sensor relies on a measuring screw controlled by a computer which attempts to bring the beam back to the reading line position. The beam is also heavily damped so that it does not react to most unwanted high frequency accelerations. However this heavily damped system is slow to react, particularly in turns where there are very high Eotvos effects. New sensor technology utilizes magnetic damping of the beam coupled with an active feedback system which acts to effectively keep the beam locked at the reading line position. The feedback system operates over the entire range of the system so there is now no requirement for a measuring screw. The feedback system operates at very high speed so that even large turbulent events have minimal impact on data quality and very little, if any, survey line data is lost because of large beam displacement errors.

    Full Text Available Abstract Background: Vegetative propagation of Fragaria sp. is traditionally carried out using stolons. This system of propagation, in addition to being slow, can spread plant diseases, particularly serious being viral. In vitro culture of meristems and the establishment of micropropagation protocols are important tools for solving these problems. In recent years, considerable effort has been made to develop in vitro propagation of the commercial strawberry in order to produce virus-free plants of high quality. These previous results can serve as the basis for developing in vitro-based propagation technologies in the less studied species Fragaria chiloensis. Results: In this context, we studied the cultivation of meristems and establishment of a micropropagation protocol for F. chiloensis. The addition of polyvinylpyrrolidone (PVP improved the meristem regeneration efficiency of F. chiloensis accessions. Similarly, the use of 6-benzylaminopurine (BAP in the culture media increased the average rate of multiplication to 3-6 shoots per plant. In addition, the use of 6-benzylaminopurine (BAP, had low levels (near zero of explant losses due to oxidation. However, plant height as well as number of leaves and roots were higher in media without growth regulators, with average values of 0.5 cm, 9 leaves and 4 roots per plant. Conclusions: For the first time in Chilean strawberry, meristem culture demonstrated to be an efficient tool for eliminating virus from infected plants, giving the possibility to produce disease free propagation material. Also, the addition of PVP into the basal MS medium improved the efficiency of plant recovery from isolated meristems. Farmers can now access to high quality plant material produced by biotech tools which will improve their technological practices.

    Continuous training of teachers, in discipline and pedagogical topics, is a key step to improve the quality of educational processes. To report the perception of Chilean teachers of undergraduate health care programs, about continuous training activities. Twenty teachers working at different undergraduate health care programs in Chile were interviewed. Maximum variation and theoretical sampling methods were used to select the sample. Data was analyzed by open coding, according to the Grounded Theory guidelines. Nine categories emerged from data analysis: Access to continuous training, meaning of training in discipline, activities of continuous training in discipline, meaning of continuous training in pedagogy, kinds of continuous training in pedagogy, quality of continuous training in pedagogy, ideal of continuous training in pedagogy, outcomes of continuous training in pedagogy and needs for continuous training in pedagogy. Teachers of health care programs prefer to participate in contextualized training activities. Also, they emphasize their need of training in evaluation and teaching strategies.

  1. Simple Tool to Evaluate Airtightness in Chilean Homes

    2016-10-01

    Full Text Available Given the high impact that air leaks have on buildings’ energy expenses, most developed countries have set out norms which regulate their presence in homes. Chile will soon begin this process; however, the airtightness revision strategy in envelopes has not been resolved as of yet. This article presents a tool to Assess Airtightness in Design, EHeD. The software will allow predicting the performance of homes under the regulations which will be set out, aiding designers, builders or owners to make decisions when making changes to improve airtightness. EHeD has been validated through pressurization tests in diverse homes across the country, with results that are in line with expectations, thus validating its calculation model. The methodology considers three stages: determining the main factors that have an impact on the airtightness in Chilean homes, preparing an airtightness database for each component (wall, windows and doors and preparing a calculation model that is integrated in an IT interface.

  2. Recovery Act: Electrochromic Glazing Technology: Improved Performance, Lower Price

    2012-06-30

    The growing dependency of the US on energy imports and anticipated further increases in energy prices reinforce the concerns about meeting the energy demand in the future and one element of a secure energy future is conservation. It is estimated that the buildings sector represents 40% of the US's total energy consumption. And buildings produce as much as one third of the greenhouse gas emissions primarily through fossil fuel usage during their operational phase. A significant fraction of this energy usage is simply due to inefficient window technology. Electrochromic (EC) windows allow electronic control of their optical properties so that the transparency to light can be adjusted from clear to dark. This ability to control the amount of solar energy allowed into the building can be advantageously used to minimize lighting, heating and air conditioning costs. Currently, the penetration of EC windows into the marketplace is extremely small, and consequently there is a huge opportunity for energy savings if this market can be expanded. In order to increase the potential energy savings it is necessary to increase the quantity of EC windows in operation. Additionally, any incremental improvement in the energy performance of each window will add to the potential energy savings. The overall goals of this project were therefore to improve the energy performance and lower the cost of dynamic (EC) smart windows for residential and commercial building applications. This project is obviously of benefit to the public by addressing two major areas: lowering the cost and improving the energy performance of EC glazings. The high level goals for these activities were: (i) to improve the range between the clear and the tinted state, (ii) reduce the price of EC windows by utilizing lower cost materials, (iii) lowering the U-Value1 SAGE Electrochromics Inc. is the only company in the US which has a track record of producing EC windows, and presently has a small operational

    1987-01-01

    The International Symposium on Improvements in Water Reactor Fuel Technology and Utilization was organized by the International Atomic Energy Agency and held in Stockholm from 15 to 19 September 1986 at the invitation of the Government of Sweden. The aim was to give scientists and engineers working in these fields the opportunity to exchange information on their achievements to date and their future work. It was attended by about 170 participants from 29 Member States and one international organization. A total of 37 papers and 12 posters covering a wide range of topics related to water reactor fuel was presented. The number of participants as well as the large number of fuel vendors from Europe, Japan and the United States of America and some reactor utilities proved that the timing and the topic of the Symposium were well chosen. In general, the Symposium has shown that current water reactor fuels perform reliably and meet current performance requirements. The factors which could limit fuel performance under high burnup conditions and load follow mode of operation were discussed and defined. All 49 presentations were divided into 6 sections: introduction (3 general papers); fuel design and performance (15 papers); fuel materials and behavior (8 papers); structural materials (5 papers); fuel fabrication (6 papers) and poster section (12 papers). A separate abstract was prepared for each of these presentations

    The accurate reproduction of the form and surface details of missing body structures is an essential part of any successful prosthetic rehabilitation. It helps mask the prosthesis and gives confidence to the patient. This clinical report details the integration of multiple in-house digital technologies of laser scanning, rapid prototyping, and digital color scanning and formulating to improve the shape, texture, orientation, and color of auricular prostheses for 3 patients with missing unilateral ears. A structured light laser scanner was used to digitize the patient's nondefect ear. The digitized data were then manipulated in specialist software and mirrored to reflect the opposing side. A rapid prototyping machine was used to manufacture a 3-dimensional (3D) model of the soft tissue required. This 3D mirrored ear model allowed the accurate reproduction of missing soft tissue. A color spectrometer was used to accurately reproduce the skin tones digitally and physically. Copyright © 2014 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

    2012-02-01

    Full Text Available The paper will explore how a social media based E-learning 2.0 solution for formal learning (social IS can be implemented, focusing on the technology acceptance process. The paper aims to increase the knowledge on how the acceptance regarding social media based E-learning 2.0 information systems for formal learning can be increased and how the acceptance affects the social learning experience. To achieve this, the paper relies on both a qualitative and quantitative approach and is primarily inductive. The paper concludes that the acceptance cannot be seen as a linear process, as is common practice. Instead, one should see the process of acceptance as interlinked with the experience and external variables in a continuous process that can either ‘spiral’ upwards or downwards. Furthermore, the paper identifies the problem of innovation resistance. The paper then analyzes information gathered from industry experts, practitioners and a live case to find how one can improve acceptance and thereby the social learning experience. Once these variables have been identified the paper presents strategic advice. The paper ends by a discussion of the results, both regarding the impact and contrast to previous research as well as highlighting areas for further research

  8. Novel technologies to improve the performance of biomass pyrolsis systems

    Science.gov (United States)

    Liaw, Shi-Shen

    Biomass pyrolysis is a thermochemical conversion process to convert lignocellosic materials into bio-oil, gas, and char. The bio-oil can be further refined to produce transportation fuels, high-value chemicals and heat. Although fast pyrolysis is a very promising technology for high bio-oil production yield, the reactors used have several technological problems that limit their future techno-economic viability. Current fast pyrolysis reactors use large quantities of carrier gas that reduce their thermal efficiency. The use of sand to accelerate heating rates results in serious attrition problems responsible for sand contamination of the bio-char produced. Most of the fast pyrolysis reactors currently used need to process very small particles which consume large quantities of energy in grinding. The bio-oil produced is also highly acidic and corrosive mainly due to the presence of acetic acid. The lack of a viable technology to use the acetic acid contained in these oils is a major challenge for the development of viable bio-oil refineries. The objective of this dissertation is to evaluate several technologies to improve the techno-economic viability of biomass pyrolysis systems. The main hypotheses of this dissertation are: (1) high yields of bio-oils could also be obtained by using auger pyrolysis reactors using very low volumes of carried gas and no sand as a heat carrier if the system is fed with very small particles (2) The grinding energy can be reduced if the biomass is torrefied. There are torrefaction conditions that will not affect the overall yield of pyrolysis products (3) Acetic acid produced during pyrolysis can be removed with the use of a fractional condensation system (4) The acids produced during the torrefaction and pyrolysis with the use of the fractional condensation system can be anaerobically digested to produce methane. In this dissertation, it was proved through Py-GC/MS studies that yield of most of the pyrolytic products can be explained

    2009-05-15

    Within this project significant results are obtained on a number of very diverse areas ranging from development of cell production, metallic creep in interconnect to assembling and test of stacks with foot print larger than 500 cm2. Out of 38 milestones 28 have been fulfilled and 10 have been partly fulfilled. This project has focused on three main areas: 1) The continued cell development and optimization of manufacturing processes aiming at production of large foot-print cells, improving cell performance and development environmentally more benign production methods. 2) Stack technology - especially stacks with large foot print and improving the stack design with respect to flow geometry and gas leakages. 3) Development of stack components with emphasis on sealing (for 2G as well as 3G), interconnect (coat, architecture and creep) and test development. Production of cells with a foot print larger than 500 cm2 is very difficult due to the brittleness of the cells and great effort has been put into this topic. Eight cells were successfully produced making it possible to assemble and test a real stack thereby giving valuable results on the prospects of stacks with large foot print. However, the yield rate is very low and a significant development to increase this yield lies ahead. Several lessons were learned on the stack level regarding 'large foot print' stacks. Modelling studies showed that the width of the cell primarily is limited by production and handling of the cell whereas the length (in the flow direction) is limited by e.g. pressure drop and necessary manifolding. The optimal cell size in the flow direction was calculated to be between approx20 cm and < 30 cm. From an economical point of view the production yield is crucial and stacks with large foot print cell area are only feasible if the cell production yield is significantly enhanced. Co-casting has been pursued as a production technique due to the possibilities in large scale production

    2012-05-31

    The principle objective of this project was to characterize and test current and next generation high performance surfactants for improved chemical flooding technology, focused on reservoirs in the Pennsylvanian-aged (Penn) sands. In order to meet this objective the characteristic curvatures (Cc) of twenty-eight anionic surfactants selected for evaluation for use in chemical flooding formulations were determined. The Cc values ranged from -6.90 to 2.55 with the majority having negative values. Crude oil samples from nine Penn sand reservoirs were analyzed for several properties pertinent to surfactant formulation for EOR application. These properties included equivalent alkane carbon numbers, total acid numbers, and viscosity. The brine samples from these same reservoirs were analyzed for several cations and for total dissolved solids. Surfactant formulations were successfully developed for eight reservoirs by the end of the project period. These formulations were comprised of a tertiary mixture of anionic surfactants. The identities of these surfactants are considered proprietary, but suffice to say the surfactants in each mixture were comprised of varying chemical structures. In addition to the successful development of surfactant formulations for EOR, there were also two successful single-well field tests conducted. There are many aspects that must be considered in the development and implementation of effective surfactant formulations. Taking into account these other aspects, there were four additional studies conducted during this project. These studies focused on the effect of the stability of surfactant formulations in the presence of polymers with an associated examination of polymer rheology, the effect of the presence of iron complexes in the brine on surfactant stability, the potential use of sacrificial agents in order to minimize the loss of surfactant to adsorption, and the effect of electrolytes on surfactant adsorption. In these last four studies

    Full Text Available We analyze the effect of two types of corporate diversification (business diversification and ownership diversification on the market value of the Chilean firms. For a sample of 83 nonfinancial firms listed on the Santiago Stock Market from 2005 to 2013, we find a discount for both business and ownership diversification, which is consistent with that reported for other economic or institutional settings. Second, we find that the business diversification discount is related to the ownership structure and is due to the excess of the largest shareholders’ control rights. Third, we find that the ownership diversification discount becomes a premium when the ownership diversification enables the control of the affiliated firms. This effect can be explained by the improvement of internal capital markets that allows overcoming the limitations of Chilean external capital markets.

    Full Text Available Chilean newborn screening program began in 1984 through of a covenant between the National Ministry of Health and the Chilean University through its Institute of Nutrition and Food Technology (INTA with the aim of implementing a pilot study for neonatal detection of phenylketonuria (PKU in Santiago’s central area. In 1989 a program for neonatal diagnosis of PKU and congenital hypothyroidism (HC was initiated by INTA along with Santiago´s occidental health ministry rural area, which covered 20% of newborn population. PKU and HC had an incidence of 1:14,640 and 1:2000 living newborns respectively. These findings allowed the establishment of a favorable cost/benefit ratio which validated the implementation of a program with National character. In 1992 the Chilean Ministry of Health ruled the initiation of PKU and HC newborn screening program and by 1998 the coverage across the country was achieved. INTA is the National Reference Center for confirmation and long term treatment for PKU and HC patients. A follow-up program consists of medical, nutritional, neurological and psychological outcome evaluations as well as periodic biochemical testing in order to guarantee normal patient growth and development. To date 184 children have been diagnosed with classic or moderate PKU, all of them follow a strict monitoring program.

    Full Text Available Chilean diets are characterized by a low supply of n-3 polyunsaturated fatty acids (n-3 PUFA, which are critical nutrients during pregnancy and lactation, because of their role in brain and visual development. DHA is the most relevant n-3 PUFA in this period. We evaluated the dietary n-3 PUFA intake and erythrocyte phospholipids n-3 PUFA in Chilean pregnant women. Eighty healthy pregnant women (20–36 years old in the 3rd–6th month of pregnancy were included in the study. Dietary assessment was done applying a food frequency questionnaire, and data were analyzed through the Food Processor SQL® software. Fatty acids of erythrocyte phospholipids were assessed by gas-liquid chromatography. Diet composition was high in saturated fat, low in mono- and PUFA, high in n-6 PUFA (linoleic acid and low in n-3 PUFA (alpha-linolenic acid and DHA, with imbalance in the n-6/n-3 PUFA ratio. Similar results were observed for fatty acids from erythrocyte phospholipids. The sample of Chilean pregnant women showed high consumption of saturated fat and low consumption of n-3 PUFA, which is reflected in the low DHA content of erythrocyte phospholipids. Imbalance between n-6/n-3 PUFA could negatively affect fetal development. New strategies are necessary to improve n-3 PUFA intake throughout pregnancy and breast feeding periods. Furthermore, it is necessary to develop dietary interventions to improve the quality of consumed foods with particular emphasis on n-3 PUFA.

DHA is the most relevant n-3 PUFA in this period. We evaluated the dietary n-3 PUFA intake and erythrocyte phospholipids n-3 PUFA in Chilean pregnant women. Eighty healthy pregnant women (20-36 years old) in the 3rd-6th month of pregnancy were included in the study. Dietary assessment was done applying a food frequency questionnaire, and data were analyzed through the Food Processor SQL® software. Fatty acids of erythrocyte phospholipids were assessed by gas-liquid chromatography. Diet composition was high in saturated fat, low in mono- and PUFA, high in n-6 PUFA (linoleic acid) and low in n-3 PUFA (alpha-linolenic acid and DHA), with imbalance in the n-6/n-3 PUFA ratio. Similar results were observed for fatty acids from erythrocyte phospholipids. The sample of Chilean pregnant women showed high consumption of saturated fat and low consumption of n-3 PUFA, which is reflected in the low DHA content of erythrocyte phospholipids. Imbalance between n-6/n-3 PUFA could negatively affect fetal development. New strategies are necessary to improve n-3 PUFA intake throughout pregnancy and breast feeding periods. Furthermore, it is necessary to develop dietary interventions to improve the quality of consumed foods with particular emphasis on n-3 PUFA.

    The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI's preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. The study provided important information about the ability of an Internet-based intervention to reduce young women's risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective. © 2014 Sigma Theta Tau International.

    The intake of fish products is a major public health concern due to possible methyl mercury exposure, which is especially toxic to the human nervous system. This pilot study (n = 46) was designed to determine mercury concentrations in fish products for national consumption (Chilean jack mackerel, hake, Chilean mussel, tuna) and for export (salmon, Patagonian toothfish, swordfish, southern hake), and to estimate the exposure of the general population. The fish products were collected from markets in Talcahuano, Puerto Montt and Santiago. Samples were analyzed at the National Environmental Center by cold vapor atomic absorption spectrophotometry. Mercury levels in swordfish and one canned tuna sample exceeded levels prescribed by national and international standards. The remaining two export products (Patagonian toothfish, also known as Chilean sea bass, and salmon) complied with international limits, which are more demanding than Chilean regulations. Theoretical estimates of mercury intake varied from 0.08 to 3.8 microg kg(-1) bw day(-1) for high fish consumers, exceeding the provisional tolerable intake for tuna, Chilean seabass, Chilean jack mackerel and swordfish. This group appears to be at the greatest risk from mercury contamination among the Chilean population.

    Full Text Available The military coup of september 11th in 1973 was the beggining of a hard dictatorship that placed Pinochet for 17 years in the chilean executive power. This fact, gave origin to many research that, from different visions, positions and ideas, intend to create an “historical conscience” among the citizens who lived in dictatorship and live in democracy today. Related to this, from the educational world, this research has a real importance as,  knowing ideas about dictatorship will allow to see the visión of this “sons of democracy” who perceive the effects of this histórical process. For chilean secondary students, the process of dictatorship was caracterised by violence because of the hard repression during the military regime to demonstrations and protest, enphasising that for them, Dictatorship and Transition are parts of the same historical period, as they relate the transition with facts and situations that happened in the military regime.

  11. HPCC technology awareness program: Improved economic competitiveness through technology awareness, transfer and application. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1994-04-01

    A need has been defined by Congress for the DOE National Laboratories to participate in various dual use and technology transfer programs. This requirement has spawned several technology transfer approaches at the DOE laboratories. These programs are designed to encourage large and small business to bring their problems and needs forward, and to allow the labs to transfer effective high performance computing technology to the commercial marketplace. This IG Technologies grant from the DOE was undertaken to address the issues and problems associated with technology transfer between the DOE National Laboratories and commercial industry. The key focus is to gain an understanding of how DOE and industry independently and collectively view the requirements and the missing elements that could allow DOE to facilitate HPCC technology transfer. At issue is HPCC Technology Transfer for the High Performance Computing industry and its relationship to the DOE National Laboratories. Several observations on this are addressed. The issue of a ``Technology Utilization Gap`` between the National Laboratories and Independent Software Vendors is discussed. This study addressed the HPCC Technology Transfer plans of all six DOE National Labs. Study team members briefed numerous industrial users of HPCC technology as to the feasibility of technology transfer for various applications. Significant findings of the effort are that the resistance to technology transfer is much higher than anticipated for both the National Labs and industry. Also, HPCC Technology Transfer is observed to be a large company`s dominion. Small businesses have a difficult time in addressing the requirements of technology transfer using Cooperative Research and Development Agreements (CRADA`s). Large businesses and the DOE National Labs however, often have requirements and objectives which are at cross purposes, making effective technology transfer difficult.

  12. Is the Chilean Diet a Mediterranean-type Diet?

    2004-01-01

    Full Text Available Food intake in Chile has changed markedly in the last decades, showing an increase in fat consumption and presently a small fruit and vegetables intake. A parallel is made between the Chilean and Mediterranean diet (mainly the one from Spain, Italy, and Greece, both currently and from 50 years ago. The main differences and similarities are based on food availability. Although Chilean diet seems to be approaching the traditional Mediterranean diet of the 60's, there is concern about changes that are moving away from Chilean traditional diet and towards a western one. A new food pyramid for Chile is proposed based on the traditional Mediterranean-type diet

  13. Are Key Principles for improved health technology assessment supported and used by health technology assessment organizations?

    2010-01-01

    Previously, our group-the International Working Group for HTA Advancement-proposed a set of fifteen Key Principles that could be applied to health technology assessment (HTA) programs in different jurisdictions and across a range of organizations and perspectives. In this commentary, we investigate the extent to which these principles are supported and used by fourteen selected HTA organizations worldwide. We find that some principles are broadly supported: examples include being explicit about HTA goals and scope; considering a wide range of evidence and outcomes; and being unbiased and transparent. Other principles receive less widespread support: examples are addressing issues of generalizability and transferability; being transparent on the link between HTA findings and decision-making processes; considering a full societal perspective; and monitoring the implementation of HTA findings. The analysis also suggests a lack of consensus in the field about some principles--for example, considering a societal perspective. Our study highlights differences in the uptake of key principles for HTA and indicates considerable room for improvement for HTA organizations to adopt principles identified to reflect good HTA practices. Most HTA organizations espouse certain general concepts of good practice--for example, assessments should be unbiased and transparent. However, principles that require more intensive follow-up--for example, monitoring the implementation of HTA findings--have received little support and execution.

    Here we summarize 10 years of effort in the development of a biomedical innovation with global projections. This innovation consists of a novel method for the production of therapeutic dendritic-like cells called Tumor Antigen Presenting Cells (TAPCells®). TAPCells-based immunotherapy was tested in more than 120 stage III and IV melanoma patients and 20 castration-resistant prostate cancer patients in a series of phase I and I/II clinical trials. TAPCells vaccines induced T cell-mediated memory immune responses that correlated with increased survival in melanoma patients and prolonged prostate-specific antigen doubling time in prostate cancer patients. Importantly, more than 60% of tested patients showed a Delayed Type Hypersensitivity (DTH) reaction against the lysates, indicating the development of anti-tumor immunological memory that correlates with clinical benefits. The in vitro analysis of the lysate mix showed that it contains damage-associated molecular patterns such as HMBG-1 protein which are capable to improve, through Toll-like receptor-4, maturation and antigen cross-presentation of the dendritic cells (DC). In fact, a Toll-like receptor-4 polymorphism correlates with patient clinical outcomes. Moreover, Concholepas concholepas hemocyanin (CCH) used as adjuvant proved to be safe and capable of enhancing the immunological response. Furthermore, we observed that DC vaccination resulted in a three-fold increase of T helper-1 lymphocytes releasing IFN-γ and a two-fold increase of T helper-17 lymphocytes capable of producing IL-17 in DTH+ with respect to DTH- patients. Important steps have been accomplished for TAPCells technology transfer, including patenting, packaging and technology assessment. Altogether, our results indicate that TAPCells vaccines constitute an exceptional Chilean national innovation of international value.

  16. Improving patient access to novel medical technologies in Europe.

    2012-02-03

    The European Society of Cardiology (ESC) organized a one-day workshop with clinicians, health economic experts, and health technology appraisal experts to discuss the equity of patient access to novel medical technologies in Europe. Two index technologies were considered: implantable cardioverter defibrillators (ICDs) and drug-eluting stents (DES). The use of ICDs range from 35 implants\\/million population in Portugal to 166 implants\\/million population in Germany, whereas for implants of DES (as percentage of total stents) it is lowest in Germany at 14% and high in Portugal at 65%. These differences can in part be explained by a lack of structured implementation of guidelines, the direct cost in relation to the overall healthcare budget, and to differences in procedures and models applied by Health Technology Assessment (HTA) agencies in Europe. The workshop participants concluded that physicians need to be involved in a more structured way in HTA and need to become better acquainted with its methods and terminology. Clinical guidelines should be systematically translated, explained, disseminated, updated, and adopted by cardiologists in Europe. Clinically appropriate, consistent and transparent health economic models need to be developed and high-quality international outcome and cost data should be used. A process for funding of a technology should be developed after a positive recommendation from HTA agencies. Both the ESC and the national cardiac societies should build-up health economic expertise and engage more actively in discussions with stakeholders involved in the provision of healthcare.

    With increasing application of blood transfusion, the research of side-effects such as transfusion-transmitted infections (TTIs) became more and more important. Up to the 90's of the 20th century, the first blood donor screening for pathogens transfected from blood transfusion entirely depended on serological test. At this time, the detection of virus were performed mainly by using method of detecting antibody, except hepatitis B virus (HBV) can be detected by hepatitis B surface antigen (HBsAg). Now, the molecular technologies, such as the polymerase chain reaction (PCR), have been used in clinic. These technologic methods can provide capability of detection for blood donor screening and reduced possibility of infection from blood transfusion. This review summarises the development of nucleic acid amplification technology and describes its current state.

  18. Improving tag/seal technologies: the vulnerability assessment component

    Jones, J.L.

    1996-01-01

    The Department of Energy (DOE), specifically the Office of Nonproliferation and National Security, has sponsored the development of numerous tag and seal technologies for high-security/high-valued applications. One important component in this technology development effort has been the continuous integration of vulnerability assessments. The Idaho National Engineering Laboratory (INEL) has been the lead laboratory for vulnerability assessments of fiber-optic-based tag/seal technologies. This paper presents a brief historical overview and the current status of the DOE high-security tag/seal development program and discusses INEL's adversarial role and assessment philosophy. Verification testing criteria used to define ''successful'' tampering attempts/attacks are discussed. Finally, the advantages of integrating a vulnerability assessment into the development of commercial security tag/seals are presented

    Construction sites are dynamic and complicated systems. The movement and interaction of people, goods and energy make construction safety management extremely difficult. Due to the ever-increasing amount of information, traditional construction safety management has operated under difficult circumstances. As an effective way to collect, identify and process information, sensor-based technology is deemed to provide new generation of methods for advancing construction safety management. It makes the real-time construction safety management with high efficiency and accuracy a reality and provides a solid foundation for facilitating its modernization, and informatization. Nowadays, various sensor-based technologies have been adopted for construction safety management, including locating sensor-based technology, vision-based sensing and wireless sensor networks. This paper provides a systematic and comprehensive review of previous studies in this field to acknowledge useful findings, identify the research gaps and point out future research directions.

    Full Text Available Introduction: The low levels of maximum oxygen consumption (VO2max evaluated in Chilean schoolchildren suggest the startup of trainings that improve the aerobic capacity. Objective: To analyze the effect of a High-intensity Interval Training method on maximum oxygen consumption in Chilean schoolchildren. Materials and methods: Thirty-two high school students from the eighth grade, who were divided into two groups, were part of the study (experimental group = 16 students and control group = 16 students. The main analyzed variable was the maximum oxygen consumption through the Course Navette Test. A High-intensity Interval training method was applied based on the maximum aerobic speed obtained through the Test. A mixed ANOVA was used for statistical analysis. Results: The experimental group showed a significant increase in the Maximum Oxygen Consumption between the pretest and posttest when compared with the control group (p < 0.0001. Conclusion: The results of the study showed a positive effect of the High-intensity Interval Training on the maximum consumption of oxygen. At the end of the study, it is concluded that High-intensity Interval Training is a good stimulation methodology for Chilean schoolchildren.

  3. Democracy and Student Discontent: Chilean Student Protest in the Post-Pinochet Era

    2015-01-01

    Full Text Available Objective indicators suggest that economic and political conditions improved in Chile between the country’s democratization in 1990 and 2011. Average incomes increased, poverty rates decreased, and the number of positive reviews of Chilean democratic institutions rose. Despite this progress, massive student-led protest waves in 2006 and 2011 demonstrated high levels of subjective discontent in Chile. This paper proposes a three-part explanation for the paradoxical emergence and escalation of the post-Pinochet-era Chilean student protests, and, in so doing, contributes to the broader understanding of social movements and political action. The first two parts of the argument relate to generational change. Firstly, a gap between expectations and capabilities provoked discontent amongst a new generation of Chilean students. Secondly, the new generation’s collective identity as “la generación sin miedo” (the fearless generation motivated the students to turn discontent into political action. Thirdly, government and student actor agency influenced the variance in protest strength between 2005 and 2011.

    Implant-retained auricular prostheses are a successful prosthetic treatment option for patients who are missing their ear(s) due to trauma, oncology, or birth defects. The prosthetic ear is aesthetically pleasing, composed of natural looking anatomical contours, shape, and texture along with good color that blends with surrounding existing skin. These outcomes can be optimized by the integration of digital technologies in the construction process. This report describes a sequential process of reconstructing a missing left ear by digital technologies. Two implants were planned for placement in the left mastoid region utilizing specialist biomedical software (Materialise, Belgium). The implant positions were determined underneath the thickest portion (of anti-helix area) left ear that is virtually simulated by means of mirror imaging of the right ear. A surgical stent recording the implant positions was constructed and used in implant fixtures placement. Implants were left for eight weeks, after which they were loaded with abutments and an irreversible silicone impression was taken to record their positions. The right existing ear was virtually segmented using the patient CT scan and then mirror imaged to produce a left ear, which was then printed using 3D printer (Z Corp, USA). The left ear was then duplicated in wax which was fitted over the defect side. Then, it was conventionally flasked. Skin color was digitalized using spectromatch skin color system (London, UK). The resultant silicone color was mixed as prescribed and then packed into the mold. The silicone was cured conventionally. Ear was trimmed and fitted and there was no need for any extrinsic coloring. The prosthetic ear was an exact match to the existing right ear in shape, skin color, and orientation due to the great advantages of technologies employed. Additionally, these technologies saved time and provided a base for reproducible results regardless of operator.

    As the world moves into the 21st century, the possibility of greater reliance on nuclear energy will impose additional technical requirements to prevent proliferation. In addition to proliferation resistant reactors, a careful examination of the various possible fuel cycles from cradle to grave will provide additional technical and nonproliferation challenges in the areas of conversion, enrichment, transportation, recycling and waste disposal. Radiation detection technology and information management have a prominent role in any future global regime for nonproliferation. As nuclear energy and hence nuclear materials become an increasingly global phenomenon, using local technologies and capabilities facilitate incorporation of enhanced monitoring and detection on the regional level. Radiation detection technologies are an important tool in the prevention of proliferation and countering radiological/nuclear terrorism. A variety of new developments have enabled enhanced performance in terms of energy resolution, spatial resolution, passive detection, predictive modeling and simulation, active interrogation, and ease of operation and deployment in the field. For example, various gamma ray imaging approaches are being explored to combine spatial resolution with background suppression in order to enhance sensitivity many-fold at reasonable standoff distances and acquisition times. New materials and approaches are being developed in order to provide adequate energy resolution in field use without the necessity for liquid nitrogen. Different detection algorithms enable fissile materials to be distinguished from other radioisotopes.

  17. How Advances in Technology Improve HIV/AIDS Care

    Full Text Available In the U.S., the number of individuals aged 50 and older who are living with HIV has increased, leading to a phenomenon called the graying of the HIV/AIDS epidemic. Advances in treating HIV have brought about a large growing population of seniors with HIV who are simultaneously facing social, psychological, and physical challenges correlated with the aging process. The stigma against HIV/AIDS has been linked to poor health, depression, and loneliness. In a recent study, about 39.1% of HIV/AIDS patients showed symptoms of major depression (C. Grov et al, 2010. Consequently, to reduce lasting effects of major depressive symptoms, there is a vital need for service providers to employ innovative efforts to confront the stigma and psychosocial and physical health problems that are characteristic of an older HIV/AIDS population. The new technological approaches to healthcare delivery have resulted in faster, more accurate diagnosis and monitoring, in more sophisticated coordination across regions and agencies, and in sophisticated risk-checking procedures. New healthcare technology that can help the AIDS/HIV patient is called Health Information Technology, a basic element of Health Relationship Management Services (HRMS, which is a new approach to healthcare. HRMS can assist individuals with HIV/AIDS in managing not only their physical, but also their mental health.

    Health information technologies have become a central fixture in the mental healthcare landscape, but few frameworks exist to guide their adaptation to novel settings. This paper introduces the Contextualized Technology Adaptation Process (CTAP) and presents data collected during Phase 1 of its application to measurement feedback system development in school mental health. The CTAP is built on models of human-centered design and implementation science and incorporates repeated mixed methods assessments to guide the design of technologies to ensure high compatibility with a destination setting. CTAP phases include: (1) Contextual evaluation, (2) Evaluation of the unadapted technology, (3) Trialing and evaluation of the adapted technology, (4) Refinement and larger-scale implementation, and (5) Sustainment through ongoing evaluation and system revision. Qualitative findings from school-based practitioner focus groups are presented, which provided information for CTAP Phase 1, contextual evaluation, surrounding education sector clinicians’ workflows, types of technologies currently available, and influences on technology use. Discussion focuses on how findings will inform subsequent CTAP phases, as well as their implications for future technology adaptation across content domains and service sectors. PMID:25677251

    Viveros-Long, A

    1986-01-01

    This paper examines the organizational and financial changes experienced by the Chilean Health System in the last 20 years. The succession of widely different political and philosophical views sponsored by the governments of Frei, Allende and Pinochet and the marked economic fluctuations experienced in the last decade have affected the organization of health care financing and the allocation of resources among the population. The trend towards a completely state financed health care system was reversed in 1973. Pinochet's government explicitely included the private sector in the provision of public health services and assigned the State a subsidiary role. Several financing mechanisms created to coopt private capital into the health system are described as well as the evolution of private and public health care expenditures. The political and economic context that shapes the allocation of limited health care resources among a population with a highly unequal income distribution may endanger the access and the quality of health care services in the country.

  3. Radiation technology for the development of improved crop varieties

    2009-01-01

    One of the peaceful applications of atomic energy is in the field of agriculture. It finds application in crop improvement, crop nutrition, crop protection and food preservation. Genetic improvement of crop plants is a continuous endeavor. Success of a crop improvement programme depends on the availability of large genetic variability, which a plant breeder can combine to generate new varieties. In nature, occurrence of natural variability in the form of spontaneous mutations is extremely low (roughly 10 -6 ), which can be enhanced to several fold (approximately 10 -3 ) by using ionizing radiations or chemical mutagens. Radiation induced genetic variability in crop plants is a valuable resource from which plant breeder can select and combine different desired characteristics to produce better crop varieties. Crop improvement programmes at Bhabha Atomic Research Centre (BARC) envisage radiation based induced mutagenesis along with recombination breeding in country's important cereals (rice and wheat), oilseeds (groundnut, mustard, soybean and sunflower), grain legumes (blackgram, mungbean, pigeonpea and cowpea), banana and sugarcane. The desirable traits which have been bred through induced mutations include higher yield, grain quality, early maturity, disease and pest resistance, improved plant type and abiotic stress resistance

    2001-01-01

    The National Standardization Institute's (INN) Metrology unit prepared a study in 1996 to evaluate the impact of metrological activity in Chile. This study was based on a survey of the supply and demand of metrological services and on studies of the behavior of the production system and technological services in Chile during the period 1990-1996. With the information obtained in this study the economic impact resulting from the lack of a national metrology system could be evaluated. This impact was estimated to be a 5% loss in gross national product equal to 125-500 million dollars because of direct product rejection in the mining, fisheries, agricultural and manufacturing sectors. Chemical measurements are responsible for 50% of these losses. In response to this need and coordinated by the INN, a metrological network of reference laboratories began to operate in 1997 for the principal physical magnitudes (mass, temperature, longitude and force) and a CORFO-FDI project began in 2001 that includes the chemical magnitudes. The Chilean Nuclear Energy Commission, aware of the problem's importance and the amount of economic damage that the country may suffer, as a result of these deficiencies, has formed a Chemical Metrology Unit to provide technical support. It aims to raise the standards of local analytical laboratories by providing international recognition to the export sector. Nuclear analytical techniques are used as reference methods. This work describes the laboratories that are included in this Chemical Metrology Unit and the historical contribution to the development of local analytical chemistry. The national and international projects are described together with the publications they have generated. The quality assurance program applied to the laboratories is described as well, which has led to the accreditation of the analytical chemical assays. The procedures used for validation and calculation of uncertain nuclear methodologies are described together with

    The strengthening of requirements for the protection of surface-water sources and increases in the cost of reagents lead to the necessity of using membrane (especially, reverse osmosis) technologies of water desalination as an alternative to ion-exchange technologies. The peculiarities of using reverse osmosis technologies in the desalination of waters with an increased salinity have been discussed. An analogy has been made between the dependence of the adsorptive capacity of ion-exchange resins on the reagent consumption during ion exchange and the dependence of the specific ion flux on the voltage in the electrodialysis and productivity of membrane elements on the excess of the pressure of source water over the osmotic pressure in reverse osmosis. It has been proposed to regulate the number of water desalination steps in reverse osmosis plants, which makes it possible to flexibly change the productivity of equipment and the level of desalinization, depending on the requirements for the technological process. It is shown that the selectivity of reverse osmotic membranes with respect to bivalent ions (calcium, magnesium, and sulfates) is approximately four times higher than the selectivity with respect to monovalent ions (sodium and chlorine). The process of desalination in reverse osmosis plants depends on operation factors, such as the salt content and ion composition of source water, the salt content of the concentrate, and the temperatures of solution and operating pressure, and the design features of devices, such as the length of the motion of the desalination water flux, the distance between membranes, and types of membranes and turbulators (spacers). To assess the influence of separate parameters on the process of reverse osmosis desalination of water solutions, we derived criteria equations by compiling problem solution matrices on the basis of the dimensional method, taking into account the Huntley complement. The operation of membrane elements was

    A critical issue in healthcare informatics is to facilitate the integration and interoperability of applications. This goal can be achieved through an open architecture based on a middleware independent from specific applications; useful for working with existing systems, as well as for the integration of new systems. Several standard organizations are making efforts toward this target. This work is based on the EN 12967-1,2,3, developed by CEN, that follows the ODP (Open Distributed Processing) methodology, providing a specification of distributed systems based on the definition of five viewpoints. However, only the three upper viewpoints are used to produce EN 12967, the two lower viewpoints should be considered in the implementation context. We are using Semantic Grid for lower views and Semantic Web and Web Services for the definition of the upper views. We analyze benefits of using these methods and technologies and expose methodology for the development of this semantic healthcare middleware observing European Standards.

    Lung, Robert Bruce; Masanet, Eric; McKane, Aimee

    2006-05-01

    For over 25 years, the U.S. DOE's Industrial Technologies Program (ITP) has championed the application of emerging technologies in industrial plants and monitored these technologies impacts on industrial energy consumption. The cumulative energy savings of more than 160 completed and tracked projects is estimated at approximately 3.99 quadrillion Btu (quad), representing a production cost savings of $20.4 billion. Properly documenting the impacts of such technologies is essential for assessing their effectiveness and for delivering insights about the optimal direction of future technology research. This paper analyzes the impacts that several emerging technologies have had in the food processing industry. The analysis documents energy savings, carbon emissions reductions and production improvements and assesses the market penetration and sector-wide savings potential. Case study data is presented demonstrating the successful implementation of these technologies. The paper's conclusion discusses the effects of these technologies and offers some projections of sector-wide impacts.

  16. Improving NASA's technology transfer process through increased screening and evaluation in the information dissemination program

    Laepple, H.

    1979-01-01

    The current status of NASA's technology transfer system can be improved if the technology transfer process is better understood. This understanding will only be gained if a detailed knowledge about factors generally influencing technology transfer is developed, and particularly those factors affecting technology transfer from government R and D agencies to industry. Secondary utilization of aerospace technology is made more difficult because it depends on a transfer process which crosses established organizational lines of authority and which is outside well understood patterns of technical applications. In the absence of a sound theory about technology transfer and because of the limited capability of government agencies to explore industry's needs, a team approach to screening and evaluation of NASA generated technologies is proposed which calls for NASA, and other organizations of the private and public sectors which influence the transfer of NASA generated technology, to participate in a screening and evaluation process to determine the commercial feasibility of a wide range of technical applications.

    In spite of the importance of innovative firms, few contributions study in depth the strategic management of their technological resources. After describing the process of strategic management of technology, we propose a model that enables the application of that process and guarantees organizational flexibility in technological companies. For it, such a process has been adapted to She wart cycle (Deeming wheel) and combined with the quality function deployment (QFD). As a result, we propose the improvement cycle of technology. It contains two matrixes that allow identifying and prioritizing with greater clarity the activities related to the management of technological resources. (Authors)

    The insertion of innovative technologies to replace baseline technologies used in cost estimation and planning of DOE D ampersand D projects is considered a high risk endeavor by project and programmatic decision makers. It is almost always considered safer to go with the open-quotes devil you knowclose quotes than use a new or untried technology, methodology or system. The decision on the specific technology to be utilized to remediate a problem is often made months or years in advance of execution, and the highly proscriptive documentation of agreements necessary to obtain stakeholder and regulator approval of remedial plans is often counterproductive to considering improved technologies

  19. Evaluating Satellite and Supercomputing Technologies for Improved Coastal Ecosystem Assessments

    Science.gov (United States)

    McCarthy, Matthew James

    Water quality and wetlands represent two vital elements of a healthy coastal ecosystem. Both experienced substantial declines in the U.S. during the 20th century. Overall coastal wetland cover decreased over 50% in the 20th century due to coastal development and water pollution. Management and legislative efforts have successfully addressed some of the problems and threats, but recent research indicates that the diffuse impacts of climate change and non-point source pollution may be the primary drivers of current and future water-quality and wetland stress. In order to respond to these pervasive threats, traditional management approaches need to adopt modern technological tools for more synoptic, frequent and fine-scale monitoring and assessment. In this dissertation, I explored some of the applications possible with new, commercial satellite imagery to better assess the status of coastal ecosystems. Large-scale land-cover change influences the quality of adjacent coastal water. Satellite imagery has been used to derive land-cover maps since the 1960's. It provides multiple data points with which to evaluate the effects of land-cover change on water quality. The objective of the first chapter of this research was to determine how 40 years of land-cover change in the Tampa Bay watershed (6,500 km2) may have affected turbidity and chlorophyll concentration - two proxies for coastal water quality. Land cover classes were evaluated along with precipitation and wind stress as explanatory variables. Results varied between analyses for the entire estuary and those of segments within the bay. Changes in developed land percent cover best explained the turbidity and chlorophyll-concentration time series for the entire bay (R2 > 0.75, p metrics were evaluated against atmospheric, meteorological, and oceanographic variables including precipitation, wind speed, U and V wind vectors, river discharge, and water level over weekly, monthly, seasonal and annual time steps.

    2014-05-01

    The European Water Framework Directive requires Member States to set water prices that provide adequate incentives for users to use water resources efficiently. These new water pricing policies need to consider cost recovery of water services, including financial, environmental and resource cost. Prices were supposed to have been set by 2010. So far the record has been mixed. The European Commission has sent reasoned opinions to a number of countries (Austria, Belgium, Denmark, Estonia, Finland, Germany, Hungary, Netherlands, Sweden) requesting them to adjust their national legislation to include all water services. Unbalanced water pricing may negatively affect the agricultural sector, especially in the southern EU countries, which are more dependent on irrigation water for production. The European Commission is funding several projects that aim to reduce the burden of increasing water prices on farmers by developing innovative technologies and decision support systems that will save water and increase productivity. The FP7 ENORASIS project (grant 282949) has developed a new integrated irrigation management decision support platform, which include high-resolution, ensemble weather forecasting, a GIS widget for the location of fields and sensors and a comprehensive decision support and database management software package to optimize irrigation water management. The field component includes wireless, solar-powered soil moisture sensors, small weather stations, and remotely controlled irrigation valves. A mobile App and a web-package are providing user-friendly interfaces for farmers, water companies and environmental consultants. In Cyprus, agricultural water prices have been set to achieve a cost recovery rate of 54% (2010). The pricing policy takes in consideration the social importance and financial viability of the agricultural sector, an important flexibility provided by the Water Framework Directive. The new price was set at 0.24 euro per m3 for water supply

    Directory of Open Access Journals (Sweden)

    Perfilov Vladimir Aleksandrovich

    2016-03-01

    Full Text Available The use of thermal insulation materials is an effective method to create an insulating envelope of a building, as well as to reduce energy costs and increase the durability of building structures. The properties of stone wool products and their operational durability is largely determined by the conditions of formation of the mineral wool carpet, uniform distribution of binder and its curing and the heat treatment conditions. Most domestic technologies are aimed at the production of mineral wool products with volume-oriented structure, which is formed using special units: spreader and corrugator placed in a production line. The next step to obtain the optimum structures is the production of dual density slabs. The denser upper layer receives mechanical loads caused by the operating conditions; the lower, less dense, but more thick layer performs the main function - insulation. The dual density slabs are produced on standard lines supplemented with a special unit, which is located in front of the heat treatment camera. Optimization of heat treatment parameters and prediction of the properties of materials is performed using software package.

  3. Improving the technology of deposition using strip electrode

    Directory of Open Access Journals (Sweden)

    Сергій Володимирович Гулаков

    2017-07-01

    Full Text Available The behavior of the arc at the strip electrode tip is studied. It is shown that the arc is moving along the electrode tip due to periodic short-circuits of the arc gap. Thus, a new arc is excited at the point where short circuit occurred after a conductive bridge formed by molten metal is vanished due to a high welding current. This leads to an increase in the probability of defect formation in the deposited layer of workpiece under treatment. To improve deposited layer quality, it is suggested to identify the moments of short-circuits of the electrode to the base metal and to discharge the pre-charged capacitorat these instants, connecting it between the electrode and the product. High discharge current pulse speeds up the destruction of the molten metal bridge between electrode tip and workpiece, thus lowering the time needed for arc re-ignition and improving depostion process stability. A special automated equipment has been developed to implement this process. Capacitor discharge is done using power thyristor with series-connected inductance for limiting discharging current rate of rise and for limiting discharge current peak value such that it is not impairing thyristor reliability. The pre-charging of the capacitor is done by an auxiliary power supply. Several thyristor-capacitor networks can be used in parallel to allow for multiple current pulses mode and to reduce RMS currents in capacitors

    This research adds to the understanding of switchgrass genetics and the increasing of biomass relevant to production of bioenergy. Switchgrass, Panicum virgatum L., and its related species are well known as potential bioenergy crops since the early 1990s. There are global economic, political, US national security and environmental pressures to increase renewable biofuel production and utilization to offset gasoline and diesel fuel use and climate change, especially in the liquid fuel transportation sector. To realize the potential of bioenergy crops, rapid genetic improvement of the most promising perennial grass feedstocks, such as switchgrass, are anticipated by current genomics, association genetics, marker assisted breeding, hybrid plant development, advanced tissue culture, conventional genetics and other approaches to increase yield, processability, and regional adaptation. The technical effectiveness and economic feasibility of the methods or techniques investigated are demonstrated by several publications, presentations and patents produced as an outcome and deliverable of this research. This project is of a broad benefit to the public not only through the dissemination of this information but also to the development of new methods which will be applied to future bioenergy crop improvement as well as other crops.

  5. The impact of Chilean migration on employment in Patagonia.

    Cariola Sanz, L

    1989-06-01

    This paper discusses the employment situation of Chilean migrant workers, their impact on labor markets in Patagonia, Argentina, and the government's past and projected responses to this phenomenon. In 1980, Chilean inhabitants of patagonia comprised 11% of the area's population. Chilean migration to patagonia was closely linked to economic activities that began to flourish in the 20th century, such as livestock raising, fruit and vegetable cultivation, and mining for coal and petroleum. No Chilean migrants work in a wide range of sectors. In Patagonia's southern provinces availability and ability to withstand rigorous climate conditions are the main factors which account for the prevalence of Chilean manpower. Chilean migrants do not in general displace local manpower. Legislation and the permeability of the border ensure that most workers enter the country as tourists. Clandestine migration is not an issue. Illegal migrants have provoked negative reactions for several reasons: 1) they comprise a marginal population without formal citizenship; 2) being employed as clandestine workers, they pay no social security, nor do their employers; 3) being illegal, they are obliged to accept lower wages and inferior working conditions which creates unfair competition within labor markets; and 4) as a result of these conditions, xenophobic and endophobic attitudes in relations with Argentine nationalists are reinforced. The government has attempted to solve these problems through various measures. Beginning in 1934, most foreigners entered Argentina with a tourist visa, becoming illegal when they stayed beyond authorized limits. Several measures over the years provided amnesty to illegal migrants. Currently, the law promotes immigration, monitors the admission of foreigners to the country and stipulates their rights and obligations. The law lists 115 articles on immigration promotion and on regulation of the movements of foreigners. Because of the present economic crisis in

    The competition for existing freshwater supplies will require a paradigmatic shift from maximizing productivity per unit of land area to maximizing productivity per unit of water consumed. This shift will, in turn, demand broad systems approaches that physically and biologically optimize irrigation relative to water delivery and application schemes, rainfall, critical growth stages, soil fertility, location, and weather. Water can be conserved at a watershed or regional level for other uses only if evaporation, transpiration, or both are reduced and unrecoverable losses to unusable sinks are minimized (e.g., salty groundwater or oceans). Agricultural advances will include implementation of crop location strategies, conversion to crops with higher economic value or productivity per unit of water consumed, and adoption of alternate drought-tolerant crops. Emerging computerized GPS-based precision irrigation technologies for self-propelled sprinklers and microirrigation systems will enable growers to apply water and agrochemicals more precisely and site specifically to match soil and plant status and needs as provided by wireless sensor networks. Agriculturalists will need to exercise flexibility in managing the rate, frequency, and duration of water supplies to successfully allocate limited water and other inputs to crops. The most effective means to conserve water appears to be through carefully managed deficit irrigation strategies that are supported by advanced irrigation system and flexible, state-of-the-art water delivery systems. Nonagricultural water users will need to exercise patience as tools reflecting the paradigmatic shift are actualized. Both groups will need to cooperate and compromise as they practice more conservative approaches to freshwater consumption.

    Ionizing radiation is shown capable of serving as an effective sanitizing treatment improving the sanitary quality of shellfish and providing an increased margin of safety for shellfish consumers. 60Co irradiation of the hard-shelled clam, Mercenaria mercenaria, and the oyster, Crassostrea virginica, significantly reduced virus carriage numbers without unduly affecting shellfish survival rates or desirable organoleptic qualities. A D10 value of 2 kGy was determined for depletion of hepatitis A virus in clams and oysters as measured by in situ hybridization fluorescent foci and cytopathology enumeration methods. A D10 value of 2.4 kGy was determined for depletion of rotavirus SA11 in clams and oysters as measured by a plaque forming unit enumeration method. Study results showed ionizing radiation capable of providing an extra, highly effective safeguard of shellfish sanitary quality when combined with traditional depuration treatment. Data drawn from other studies is introduced which shows D10 values as low as 1.0 kGy effectively eliminate Vibrio cholerae, and V. parahemolyticus, from shellfish

  11. Improving Technological Competency in Nursing Students: The Passport Project

    Full Text Available Integration of informatics competency into a nursing curriculum is important to ensure success throughout the education and career of contemporary nursing students. As enrollment in nursing programs increases, the diverse population of students from many different cultural and socioeconomic backgrounds presents a challenge for faculty in addressing unique learning needs. Competency in informatics will allow the beginning nursing student to navigate the on-line teaching software used by colleges. With rigorous expectations in nursing programs, students may feel overwhelmed with assignments, organization, and time management. Frustration may build when students struggle with basic informatics competency, often leaving them unable to navigate instructional websites or work with necessary on-line learning content. The purpose of this project, Passport Project for Nursing Success, was to assess the skills, knowledge, and informatics comfort level of students, while providing computer training and teaching for beginning nursing students in an undergraduate nursing program in Central Illinois. The community college encompassed students from a ten county area, with 20 percent of the student population enrolled in the Applied Science curriculum. Initial implementation occurred prior to the students' first nursing course and emphasized basic skills necessary to navigate on-line learning software, library search engines, and electronic communication. The greatest barrier to successful implementation was faculty resistance and academic support during completion of the initial implementation of the Passport Project. Post- project surveys indicated overwhelming student support for the education received and improved retention rates of first semester nursing students.

    It has now been 13 years since the first cloned mammal Dolly the sheep was generated from somatic cells using nuclear transfer (SCNT). Since then, this technique has been considered an important tool not only for animal reproduction but also for regenerative medicine. However, the success rate is still very low and the mechanisms involved in genomic reprogramming are not yet clear. Moreover, the NT technique requires donated fresh oocyte, which raises ethical problems for production of human cloned embryo. For this reason, the use of induced pluripotent stem cells for genomic reprogramming and for regenerative medicine is currently a hot topic in this field. However, we believe that the NT approach remains the only valid way for the study of reproduction and basic biology. For example, only the NT approach can reveal dynamic and global modifications in the epigenome without using genetic modification, and it can generate offspring from a single cell or even a frozen dead body. Thanks to much hard work by many groups, cloning success rates are increasing slightly year by year, and NT cloning is now becoming a more applicable method. This review describes how to improve the efficiency of cloning, the establishment of clone-derived embryonic stem cells and further applications.

    Feature-based systems that combine imaging and signal analysis capabilities may be useful for nondestructive evaluation (NDE) of plant components. This report describes the metallurgical evaluation conducted to verify the performance of a feature-based system to discriminate intergranular stress corrosion cracking (IGSCC) from benign geometrical reflectors. The ultrasonic examination results were also evaluated by examination personnel trained in intergranular stress corrosion cracking (IGSCC) detection techniques. The welds were examined prior to their removal from the recirculation and Residual-Heat-Removal (RHR) piping systems of the Peach Bottom Atomic Power Plant, as described in the Phase 2 Interim Report issued in June 1989. In this phase of the program, a metallurgical evaluation was performed on piping system welds that were examined ultrasonically using a feature-based system for analysis. The feature-based system correctly identified crack, but incorrectly identified other features, e.g., root geometry and metallurgical interfaces, as cracks. While the results of the analysis by the feature-based system were not identical to the results of analysis by trained personnel, the overall performance of the feature-based system was comparable to that of the trained personnel. Based on the results of this program, the feature-based system may be useful as a supplementary method of identifying IGSCC indications. When used in conjunction with existing methods and techniques, it could improve the accuracy of IGSCC identification

    Common misconceptions of p-values are based on certain beliefs and attributions about the significance of the results. Thus, they affect the professionals' decisions and jeopardize the quality of interventions and the accumulation of valid scientific knowledge. We conducted a survey on 164 academic psychologists (134 Italian, 30 Chilean) questioned on this topic. Our findings are consistent with previous research and suggest that some participants do not know how to correctly interpret p-values. The inverse probability fallacy presents the greatest comprehension problems, followed by the replication fallacy. These results highlight the importance of the statistical re-education of researchers. Recommendations for improving statistical cognition are proposed.

    The immunomodulatory effect of hydrosoluble extracts of four Chilean Cyttaria species (Discomycetes, Fungi) was assessed in mice with L5178Y lymphoma. Oral administration of 100 mg extract per day for 7 days enhanced the percentual phagocytosis and phagocytosis index in animals receiving Cyttaria berteroi, Cyttaria darwinii, Cyttaria espinosae and Cyttaria harioti extracts. Differences in the digestion index were observed in mice treated with C. darwinii and C. berteroi. In the delayed-type hypersensitivity model, only C. harioti was able to modify the immune response. The results suggest that intake of Cyttaria can improve the immune system of consumers.

    Full Text Available The military and civilian glories of the republic are melted through the history since the founding of the Chilean nation and the subsequent development of its culture and national identity. In that process the military dimension of its defense, as well as the civilian part of development, are inseparable constants in the building of its republican institutionalism. This is a consequence of the long war of Arauco; the isolation of the country of the main centers of world attraction and their migratory flows; the austerity of colonial life and the particularities of its political and social process until the 19th century. From the melting of the mapuche and Hispanic races arises a new nation that takes its own life in the person of Creole. Being he, the Creole, the one who consolidates, with the sword, the forge and the plough, a free, independent and sovereign Republican State that, after two centuries, remains the political expression of a society with a unique culture and identity.

  17. Risk segmentation in Chilean social health insurance.

    2013-01-01

    The objective of this study is to identify how risk and social variables are likely to be impacted by an increase in private sector participation in health insurance provision. The study focuses on the Chilean health insurance industry, traditionally dominated by the public sector. Predictive risk modelling is conducted using a database containing over 250,000 health insurance policy records provided by the Superintendence of Health of Chile. Although perceived with suspicion in some circles, risk segmentation serves as a rational approach to risk management from a resource perspective. The variables that have considerable impact on insurance claims include the number of dependents, gender, wages and the duration a claimant has been a customer. As shown in the case study, to ensure that social benefits are realised, increased private sector participation in health insurance must be augmented by regulatory oversight and vigilance. As it is clear that a "community-rated" health insurance provision philosophy impacts on insurance firm's ability to charge "market" prices for insurance provision, the authors explore whether risk segmentation is a feasible means of predicting insurance claim behaviour in Chile's private health insurance industry.

    Modern economy, in first order Retail sector, are introducing new and modern technologies which improve sales, communication with customers as well as marketing decision process. Retail sector is more and more oriented to technologies which improve not just communication with possible customers but also information gathering for better decision making process. Among those technologies special place is given to Indoor Positioning Systems (IPS) technologies, specialized technologies which are used for locating the people and objects but also their movement as well as for communication with clients in the store. These technologies follows customers in the store, follow their movement across, communicate with them about offers and promotions but also are base for predictive marketing of retail sector which has a goal to achieve „offer to customers what they look for and what they really need“. These technologies are in limited usage in Banja Luka area but potential for their use is present. There is no enough demand from retails industry but having in mind that these technologies are raising in modern economies as well as predictions and trends it is to be expected that those technologies will be implemented in retail sector in this region too.

    The purpose of this document is to describe a global strategy to integrate the use of space technology in the fight against malaria. Given the well-documented relationship between the vector and its environment, and the ability of existing space technologies to monitor environmental factors, malaria is a strong candidate for the application of space technology. The concept of a malaria early warning system has been proposed in the past' and pilot studies have been conducted. The HI-STAR project (Health Improvement through Space Technologies and Resources) seeks to build on this concept and enhance the space elements of the suggested framework. As such, the mission statement for this International Space University design project has been defined as follows: "Our mission is to develop and promote a global strategy to help combat malaria using space technology". A general overview of malaria, aspects of how space technology can be useful, and an outline of the HI-STAR strategy is presented.

    2011-01-01

    This paper contributes to the debate about climate change technology transfer by analysing barriers and enablers for a Chilean company starting up the production of wind blades. Literature on the role of technology transfer for the development and deployment of local renewable energy technologies in developing countries often refers to success stories in Brazil, India and China. Instead, this case study highlights the different challenges faced by smaller emerging economies. The paper argues that successful technology transfer in a smaller economy like Chile requires: a minimum internal demand and access to regional markets to attract foreign knowledge providers; a focus in the types of technologies where the recipient country or company have a competitive advantage; and active learning processes by the recipient company. Lessons are drawn for improving the design and implementation of technology-push and market-pull policies in small or medium emerging economies. - Highlights: → We analyse the case of a Chilean company starting up wind blades production. → Technology transfer is required as the relevant knowledge is not available in the country. → We examine the factors that enable technology transfer to draw policy conclusions. → We highlight the particularities of medium sized developing countries.

    Health information technology (HIT) interventions may improve neonatal patient safety but may also introduce new errors. The objective of this review was to evaluate the evidence for use of HIT interventions to improve safety in neonatal care. Evidence for improvement exists for interventions like computerized provider order entry in the neonatal population, but is lacking for several other interventions. Many unique applications of HIT are emerging as technology and use of the electronic health record expands. Future research should focus on the impact of these interventions in the neonatal population. Copyright © 2017 Elsevier Inc. All rights reserved.

    2003-07-01

    In Chile there has been a close interaction between medical teaching and health care. In 1943, the University of Chile School of Medicine (founded in 1833) created Chairs in several public hospitals. The University of Chile School of Public Health (founded in 1943) played a key role in the creation in 1952 of a centralized National Health Service (NHS). The NHS had outpatient clinics and hospitals all over the country and was responsible for health care and for the promotion of health and disease prevention programs. In 1954, the NHS and the School of Medicine set up Residencies and General Practitioners programs aimed at improving the distribution of specialists and general practitioners throughout the country. In 1979, the NHS was replaced with 27 autonomous Health Services headed by the Ministry of Health, while the administration of primary care outpatient clinics was transferred to the municipal government. However, sanitary programs were still managed at the central level. Higher education also expanded and was decentralized. There are currently 60 universities and 17 medical schools, compared to eight and six, respectively, in 1981. The number of students in higher education has increased by 370% in 20 years. At the present time, the Chilean health case system is a predominantly public system with a strong and sizeable private system. Sixty two percent of the population is covered by public health insurance, while 27% is covered by private insurance. New and well equipped private clinics have multiplied. Private non profit institutions manage the prevention and treatment of work related injuries and diseases. Chile's outstanding health indicators (fertility rate: 17.2 x 1,000; mortality: 5.4 x 1,000; maternal mortality: 2.3 x 10,000; neonatal mortality: 4.5 x 1,000; life expectancy: 76 years) are a direct consequence of the improved social, cultural and economic condition of the general populations as well as of the sanitary programs sustained over the past

    The growing complexity of technology, equipment, and devices involved in patient care delivery can be staggering and overwhelming. Technology is intended to be a tool to help clinicians, but it can also be a frustrating hindrance if not thoughtfully planned and strategically aligned. Critical care nurses are key partners in the collaborations needed to improve safety and quality through health information technology (IT). Nurses must advocate for systems that are interoperable and adapted to the context of care experiences. The involvement and collaboration between clinicians, information technology specialists, biomedical engineers, and vendors has never been more relevant and applicable. Working together strategically with a shared vision can effectively provide a seamless clinical workflow, maximize technology investments, and ultimately improve patient care delivery and outcomes. Developing a strategic integrated clinical and IT roadmap is a critical component of today's health care environment. How can technology strategy be aligned from the executive suite to the bedside caregiver? What is the model for using clinical workflows to drive technology adoption? How can the voice of the critical care nurse strengthen this process? How can success be assured from the initial assessment and selection of technology to a sustainable support model? What is the vendor's role as a strategic partner and "co-caregiver"?

    Full Text Available The purpose of the study is to show the perspective of Chilean mothers on the educational inclusion of children who have Autism Spectrum Disorder enrolled in primary schools. Evidence was collected by listening to the voices of families, which can serve as a starting point to reflect on how to move towards a more inclusive education and how to help improve the supports that are being provided to students with disabilities. The study was based on a qualitative research paradigm, using unstructured interviews to access the information. It counted with the participation of eight Chilean mothers from the Region of Valparaíso. The results show that the value of schooling is closely related to the emotional well-being, which is given greater significance than the academic results. The importance of supports adapted to the needs of the family system is emphasized.

    Law enforcement agencies play a key role in protecting the nation from and responding to terrorist attacks. Preventing terrorism and promoting the nation"s security is the Department of Justice"s number one strategic priority. This is reflected in its technology development efforts, as well as its operational focus. The National Institute of Justice (NIJ) is the national focal point for the research, development, test and evaluation of technology for law enforcement. In addition to its responsibilities in supporting day-to-day criminal justice needs in areas such as less lethal weapons and forensic science, NIJ also provides critical support for counter-terrorism capacity improvements in state and local law enforcement in several areas. The most important of these areas are bomb response, concealed weapons detection, communications and information technology, which together offer the greatest potential benefit with respect to improving the ability to law enforcement agencies to respond to all types of crime including terrorist acts. NIJ coordinates its activities with several other key federal partners, including the Department of Homeland Security"s Science and Technology Directorate, the Technical Support Working Group, and the Department of Defense.

    This study was aimed to set reference values of hand-grip strength by age and sex and validate cut points for risk of functional limitation and mortality in older Chileans. This was a pooled analysis of four studies including 6,426 people ≥60 years of nondependent community-dwelling Chileans. After exclusion criteria, the final sample included 5,250 subjects, from whom 2,193 were followed to study all-cause mortality associated with low hand-grip strength. Face-to-face interviews registering sociodemographic characteristics, self-reported chronic diseases, and functional limitations were conducted. Anthropometric measurements and observed mobility were performed by trained professionals. Hand-grip strength was measured with a hand dynamometer T-18 (Country Technology, Inc.) before 2008 or with JAMAR brand from 2008 onwards. Percentiles were calculated through descriptive analysis and quantile regression models for specific groups of age and sex. Adjusted Cox regression hazard models for mortality risk according to low dynamometry condition and covariates were developed. We deliver reference values of hand-grip strength for older Chileans proposing the 25th percentile as the cut-off point for low dynamometry risk: men ≤27 kg, women ≤15 kg. Low hand-grip strength was associated with Instrumental Activities of Daily Living limitations ( p =0.001), and altered physical performance evaluated through the Timed Up and Go test ( p =0.0001), grasping ( p =0.001), bending ( p dynamometry validated for the older Chileans allow the incorporation in the geriatric evaluation in primary health care of an easy-to-use, inexpensive indicator to identify older adults at risk of sarcopenia, frailty, and dismobility. In addition this also helps to optimize the evaluation of intervention strategies focused on the maintenance of functionality.

    Full Text Available Can a significant technological improvement make an economically justifiable contribution to a financial market's development? The Johannesburg Stock Exchange (JSE incorporated the SETS system from the London Stock Exchange in 2002. It is certain that SETS is a technologically efficient trading system, and it would undoubtedly improve trading in the JSE. We test whether SETS represents a structural break by examining whether there was an increase in the JSE's liquidity, market efficiency and international integration after the introduction of SETS. While SETS is certainly a technological improvement with increased liquidity, it is not a sufficient factor to render it efficient. After the incorporation of SETS, the JSE has become more independent and it now offers better diversification opportunities for international investors.

    The ground shaking assessment allows quantifying the hazards associated with the occurrence of earthquakes. Chile and western Canada are two areas that have experienced, and are susceptible to imminent large crustal, in-slab and megathrust earthquakes that can affect the population significantly. In this context, we compare the current GMPEs used in the 2015 National Building Code of Canada and the most recent GMPEs calculated for Chile, with observed accelerations generated by four recent Chilean megathrust earthquakes (MW ≥ 7.7) that have occurred during the past decade, which is essential to quantify how well current models predict observations of major events.We collected the 3-component waveform data of more than 90 stations from the Centro Sismologico Nacional and the Universidad de Chile, and processed them by removing the trend and applying a band-pass filter. Then, for each station, we obtained the Peak Ground Acceleration (PGA), and by using a damped response spectra, we calculated the Pseudo Spectral Acceleration (PSA). Finally, we compared those observations with the most recent Chilean and Canadian GMPEs. Given the lack of geotechnical information for most of the Chilean stations, we also used a new method to obtain the VS30 by inverting the H/V ratios using a trans-dimensional Bayesian inversion, which allows us to improve the correction of observations according to soil conditions.As expected, our results show a good fit between observations and the Chilean GMPEs, but we observe that although the shape of the Canadian GMPEs is coherent with the distribution of observations, in general they under predict the observations for PGA and PSA at shorter periods for most of the considered earthquakes. An example of this can be seen in the attached figure for the case of the 2014 Iquique earthquake.These results present important implications related to the hazards associated to large earthquakes, especially for western Canada, where the probability of a

    Full Text Available The main source for the development of construction projects with energy-efficient technologies in use is investments. The traditional approaches of risk management: insurance, diversification and redundancy only raise the cost of the construction project, which has a negative impact on the investor’s decision to invest. In order to solve this problem an information system has been developed, which is based on the principle of insightful analysis of the potential “pure” risks and a list of recommendations of risk management. This tool allows identifying all the weaknesses of a construction project, improving the organizational and technological reliability, and imparting an understanding to the investor / a customer of the resources required for the project implementation.

  8. A critical review of the Chilean civil nuclear liability regime

    International Nuclear Information System (INIS)

    Gonzalez Cruz, Francisco Javier; Acevedo Ferrer, Santiago

    2013-01-01

    This article reviews the Chilean civil nuclear liability regime. The Nuclear Security Act (Law 18.302), enacted in 1984, and the Vienna Convention on Civil Liability for Nuclear Damage, ratified ed by Chile in 1989, are the fundamental laws of the current regime. Although Chile has no nuclear power plants, it is still important to analyze how the Chilean legislation would protect citizens from nuclear damages. This paper does not consider the policy reasons for and against the promotion of atomic energy. Rather, it critically examines the current status of the Chilean nuclear regime. Undoubtedly, if in the future Chile chooses to include nuclear sources in its energy mix, it will not be enough to introduce some isolated legal amendments, but it will be necessary to build a new Chilean Energy Regime which includes nuclear energy. In that scenario, though, it will be useful to know and understand how the current nuclear liability regime works. From this point of view, the reforms this article proposes to the current nuclear liability regime might be helpful to academics and policy makers alike

    Medical errors, in particular medication errors, continue to be a troublesome factor in the delivery of safe and effective patient care. Antineoplastic agents represent a group of medications highly susceptible to medication errors due to their complex regimens and narrow therapeutic indices. As the majority of these medication errors are frequently associated with breakdowns in poorly defined systems, developing technologies and evolving workflows seem to be a logical approach to provide added safeguards against medication errors. This article will review both the pros and cons of today's technologies and their ability to simplify the medication use process, reduce medication errors, improve documentation, improve healthcare costs and increase provider efficiency as relates to the use of antineoplastic therapy throughout the medication use process. Several technologies, mainly computerized provider order entry (CPOE), barcode medication administration (BCMA), smart pumps, electronic medication administration record (eMAR), and telepharmacy, have been well described and proven to reduce medication errors, improve adherence to quality metrics, and/or improve healthcare costs in a broad scope of patients. The utilization of these technologies during antineoplastic therapy is weak at best and lacking for most. Specific to the antineoplastic medication use system, the only technology with data to adequately support a claim of reduced medication errors is CPOE. In addition to the benefits these technologies can provide, it is also important to recognize their potential to induce new types of errors and inefficiencies which can negatively impact patient care. The utilization of technology reduces but does not eliminate the potential for error. The evidence base to support technology in preventing medication errors is limited in general but even more deficient in the realm of antineoplastic therapy. Though CPOE has the best evidence to support its use in the

  11. An Analysis of Sources of Technological Change in Efficiency Improvement of Fluorescent Lamp Systems

    In Japan, energy efficient fluorescent lamp systems which use “rare-earth phosphors” and “electronic ballasts” have shown rapid diffusion since 1990s. This report investigated sources of technological change in the efficiency improvement of fluorescent lamp systems: (i) Fluorescent lamp and luminaires have been under steady technological development for getting more energy efficient lighting and the concepts to achieve high efficiency had been found in such activities; however, it took long time until they realized and become widely used; (ii) Electronic ballasts and rare-earth phosphors add fluorescent lamp systems not only energy efficiency but also various values such as compactness, lightweight, higher output, and better color rendering properties, which have also been expected and have induced research and development (R&D) (iii) Affordable electronic ballasts are realized by the new technology “power MOSFET” which is based on IC technologies and has been developed for large markets of information and communication technologies and mobile devices; and (iv) Rare-earth phosphors became available after rare-earth industries developed for the purpose of supplying rare-earth phosphors for color television. In terms of sources of technological change, (i) corresponds to “R&D” aiming at the particular purpose i.e. energy efficiency in this case, on the other hand, (ii), (iii), and (iv) correspond to “spillovers” from activities aiming at other purposes. This case exhibits an actual example in which “spillovers” were the critical sources of technological change in energy technology.

    The scapula is valuable for sex estimation in human skeletons. Muscles provide protection to the scapula making it difficult to fracture, therefore increasing the potential for undamaged scapulae at forensic scenes. The goal of this project is to evaluate the accuracy of discriminant functions, created using an indigenous Guatemalan and contemporary Mexican population, when applied to a contemporary Chilean sample for estimation of sex from the scapula. The length of the glenoid cavity (LGC) and breadth of the glenoid cavity (BGC) were measured. The sample included 114 individuals (58 males and 56 females) with age ranges from 17 to 85years old. When the Guatemalan discriminant functions were applied to the Chilean sample they showed higher accuracy rates for sexing male scapulae (89.6% to 94.8%) than for sexing female scapulae (53.4% to 80.3%). When the Mexican discriminant functions were applied to the Chilean sample they showed higher accuracy rates for sexing female scapulae (82.1% to 96.4%) than for sexing male scapulae (56.9% to 89.6%). Size comparisons were made to a Guatemalan, Mexican, White American, and Greek population. Overall, in males and females of the Chilean population both left and right scapulae were larger than in the Guatemalan population but smaller than in the Mexican, White American, and Greek samples. Population-specific discriminant functions were created for the Chilean population with an overall sex classification accuracy rate of 80.7% to 86.0%.

    The development of high-tech industry has been prosperous around the world in past decades, while technology and finance have already become the most significant issues in the information era. While high-tech firms are a major force behind a country's economic development, it requires a lot of money for the development process, as well as the financing difficulties for its potential problems, thus, how to evaluate and establish appropriate technology and financial services platforms innovation strategy has become one of the most critical and difficult issues. Moreover, how the chosen intertwined financial environment can be optimized in order that high-tech firms financing problems can be decided has seldom been addressed. Thus, this research aims to establish a technology and financial services platform innovation strategy improvement model, as based on the hybrid MADM model, which addresses the main causal factors and amended priorities in order to strengthen ongoing planning. A DEMATEL technique, as based on Analytic Network Process, as well as modified VIKOR, will be proposed for selecting and re-configuring the aspired technology and financial services platform. An empirical study, as based on China's technology and financial services platform innovation strategy, will be provided for verifying the effectiveness of this proposed methodology. Based on expert interviews, technology and financial services platforms innovation strategy improvement should be made in the following order: credit guarantee platform ( C )_credit rating platform ( B )_investment and finance platform ( A ).

    The study examined the impact of improved technologies on the lives of small-scale soybean farmers in Benue State, Nigeria. A total of 160 respondents were selected using simple random sampling technique. Data were analyzed using descriptive statistics, Tobit model and the Kruskal-Wallis test. Findings revealed that 35.6% of the respondents were between 31 and 40 years old, 40.6% had household size of between 6 and 10 members. Majority of the respondents were male, married, and had secondary school education. Tobit analysis revealed that farmers socioeconomic characteristics which include gender, educational status and farming experience; and farmers knowledge on soybean innovations were significant factors determining the adoption of improved soybean production technologies. These factors were statistically significant at p=0.05. The adoption of improved soybean technologies has had a clear positive impact on farmers belief on soybean innovations. The major problems facing farmers in the adoption of improved soybean production technologies according to Kruskal-Wallis ranking were high cost of inputs, problem of labour availability and lack of credit/loan. The results of this study provide a strong case for the promotion of soybean as a solution for malnutrition and a means of poverty alleviation for poor people. (author)

    Martinez-Gutierrez, María Soledad; Cuadrado, Cristóbal

    2017-06-01

    The Chilean health system has experienced important transformations in the last decades with a neoliberal turn to privatization of the health insurance and healthcare market since the Pinochet reforms of the 1980s. During 20 years of center-left political coalition governments several reforms were attempted to regulate and reform such markets. This paper analyzes regulatory policies for the private health insurance and health care delivery market, adopted during the 1990-2010 period. A framework of variation in market types developed by Gingrich is adopted as analytical perspective. The set of policies advanced in this period could be expected to shift the responsibility of access to care from individuals to the collective and give control to the State or the consumers vis a vis producers. Nevertheless, the effect of the implemented reforms has been mixed. Regulations on private health insurers were ineffective in terms of shifting power to the consumer or the state. In contrast, the healthcare delivery market showed a trend of increasing payers' and consumers' control and the set of implemented reforms partially steered the market toward collective responsibility of access by creating a submarket of guaranteed services (AUGE) with lower copayments and fully funded services. Emerging unintended consequences of the adopted policies and potential explanations are discussed. In sum, attempts to use regulation to improve the collective dimension of the Chilean health system has enabled some progress, but several challenges had persisted. Copyright © 2017 Elsevier Ltd.

    Oñate, Esteban; Meyer, Felipe; Espinoza, Jorge

    2012-01-01

    The range of sizes used in Chile for clothing comes from criteria developed in continental Europe, mainly the EN 13402 standard. Any standard adopted by a country should consider the anthropometric dimensions of the user population, particularly to discern the ratio of garments for different size. Consequently, the purpose of this study was to propose standards for the size of clothing based on anthropometric characteristics of a sample of Chilean miners. The study was conducted in 447 male workers. The age and body weight were measured in each workers as well as their percentage of body fat. Anthropometric measurements for garments were made according to the criteria of the European Community (EN 13402-1) and ISO (8559- 1989). Body dimensions for the design of gloves, shoes, helmets and caps, clothes that cover the upper part of the body and clothes that cover the lower part were measured. The results obtained made it possible to establish the percentage of workers falling within the range of sizes that manufacturers consider as reference. One of the main conclusions of the study is the need to carefully consider a set of complementary anthropometric measures, which can help to improve the comfort of costumes, to the extent that the providers adapt their designs to the characteristics of Chilean workers.

    E-health tools have the potential to improve the quality of care for ophthalmic patients, many of whom have chronic conditions. However, little research has assessed ophthalmic patients' use or acceptance of technological devices and social media platforms for health-related purposes. The present study evaluated utilization of technological devices and social media platforms by eye clinic patients, as well as their willingness to receive health reminders through these technologies. A 31-item paper questionnaire was administered to eye clinic patients (n=843) at an urban, tertiary-care center. Questions focused on technology ownership, comfort levels, frequency of use, and preferences for receiving health reminders. Demographic data were also recorded. Eye clinic patients most commonly owned cellular phones (90%), landline phones (81%), and computers (80%). Overall, eye clinic patients preferred to receive health reminders through phone calls and e-mail and used these technologies frequently and with a high level of comfort. Less than 3% of patients preferred using social networking to receive health reminders. In addition, age was significantly associated with technology ownership, comfort level, and frequency of use (p<0.05). The majority of patients 18-45 years of age preferred to receive appointment reminders via text message (57%) and e-mail (53%). This age group also used these technologies more frequently and with a higher comfort level (p<0.001). These data support the proposal that e-mail and text-messaging e-health tools are likely to be immediately adopted by eye clinic patients and therefore have the greatest potential to improve health outcomes and increase quality of care. Eye clinic patients are interested in these technologies for appointment reminders, general eye and vision health information, asking urgent medical questions, and requesting prescription refills. Future controlled trials could further explore the efficacy of e-health tools for these

    Background Many eHealth technologies are not successful in realizing sustainable innovations in health care practices. One of the reasons for this is that the current development of eHealth technology often disregards the interdependencies between technology, human characteristics, and the socioeconomic environment, resulting in technology that has a low impact in health care practices. To overcome the hurdles with eHealth design and implementation, a new, holistic approach to the development of eHealth technologies is needed, one that takes into account the complexity of health care and the rituals and habits of patients and other stakeholders. Objective The aim of this viewpoint paper is to improve the uptake and impact of eHealth technologies by advocating a holistic approach toward their development and eventual integration in the health sector. Methods To identify the potential and limitations of current eHealth frameworks (1999–2009), we carried out a literature search in the following electronic databases: PubMed, ScienceDirect, Web of Knowledge, PiCarta, and Google Scholar. Of the 60 papers that were identified, 44 were selected for full review. We excluded those papers that did not describe hands-on guidelines or quality criteria for the design, implementation, and evaluation of eHealth technologies (28 papers). From the results retrieved, we identified 16 eHealth frameworks that matched the inclusion criteria. The outcomes were used to posit strategies and principles for a holistic approach toward the development of eHealth technologies; these principles underpin our holistic eHealth framework. Results A total of 16 frameworks qualified for a final analysis, based on their theoretical backgrounds and visions on eHealth, and the strategies and conditions for the research and development of eHealth technologies. Despite their potential, the relationship between the visions on eHealth, proposed strategies, and research methods is obscure, perhaps due to a

    Radiology report signature time (ST) can be a substantial component of total report turnaround time. Poor turnaround time resulting from lengthy ST can adversely affect patient care. The combination of technology adoption with financial incentive was evaluated to determine if ST improvement can be augmented and sustained. This prospective study was performed at a 751-bed, urban, tertiary care adult teaching hospital. Test-site imaging volume approximated 48,000 examinations per month. The radiology department has 100 trainees and 124 attending radiologists serving multiple institutions. Over a study period of 4 years and 4 months, three interventions focused on radiologist signature performance were implemented: 1) a notification paging application that alerted radiologists when reports were ready for signature, 2) a picture archiving and communications systems (PACS)-integrated speech recognition report generation system, and 3) a departmental financial incentive to reward radiologists semiannually for ST performance. Signature time was compared before and after the interventions. Wilcoxon and linear regression statistical analyses were used to assess the significance of trends. Technology adoption (paging plus speech recognition) reduced median ST from >5 to 24 to 15 to 18 hours (P financial incentive further improved 80th-percentile ST to 4 to 8 hours (P Technology interventions coupled with financial incentive can result in synergistic and sustainable improvement in radiologist report-signing behavior. The addition of a financial incentive leads to better performance than that achievable through technology alone.

  11. Improving vaccine registries through mobile technologies: a vision for mobile enhanced Immunization information systems.

    2016-01-01

    Immunization registries or information systems are critical to improving the quality and evaluating the ongoing success of immunization programs. However, the completeness of these systems is challenged by a myriad of factors including the fragmentation of vaccine administration, increasing mobility of individuals, new vaccine development, use of multiple products, and increasingly frequent changes in recommendations. Mobile technologies could offer a solution, which mitigates some of these challenges. Engaging individuals to have more control of their own immunization information using their mobile devices could improve the timeliness and accuracy of data in central immunization information systems. Other opportunities presented by mobile technologies that could be exploited to improve immunization information systems include mobile reporting of adverse events following immunization, the capacity to scan 2D barcodes, and enabling bidirectional communication between individuals and public health officials. Challenges to utilizing mobile solutions include ensuring privacy of data, access, and equity concerns, obtaining consent and ensuring adoption of technology at sufficiently high rates. By empowering individuals with their own health information, mobile technologies can also serve as a mechanism to transfer immunization information as individuals cross local, regional, and national borders. Ultimately, mobile enhanced immunization information systems can help realize the goal of the individual, the healthcare provider, and public health officials always having access to the same immunization information. © The Author 2015.

    This paper investigates the problems associated with heat loss occurring at the points of needle insertion. The insulation material at stitching points is compressed by sewing thread tensions and consequently the air entrapped is forced to leave its structure. It results in poor thermal insulation at the points of needle insertions. An innovative material feeding technology, ‘Spacer stitching’ is developed which addresses the state of the art of cold spots with a simpler and much efficient method. A comparison of sewing samples of conventional sewing technology with the spacer stitching is carried out in this research paper to study the improvement in thermal properties.

    2010-01-01

    From the mid eighties on, most of Latin American Countries reformed their energy systems. The impact of these reforms over electricity markets was different in each case. However, in the majority of these cases there was a shift to private participation, instead of State, and a convergence of electricity systems to hydro and thermal technologies. This is the case of Argentina and Chile. In this context, the aim of this paper is to discuss the current situation of renewable energies in Chilean and Argentinean electric markets and the potential to increase their share in total energy supply. To this purpose, we firstly study electricity deregulation process and its current situation. Secondly, we analyze renewable energy share in these electricity systems comparatively to worldwide situation. Finally, we briefly present the policy instruments used in each country. (author)

    Cooper completed an investigation into new tire technology using a novel approach to develop and demonstrate a new class of fuel efficient tires using innovative materials technology and tire design concepts. The objective of this work was to develop a new class of fuel efficient tires, focused on the “replacement market” that would improve overall passenger vehicle fuel efficiency by 3% while lowering the overall tire weight by 20%. A further goal of this project was to accomplish the objectives while maintaining the traction and wear performance of the control tire. This program was designed to build on what has already been accomplished in the tire industry for rolling resistance based on the knowledge and general principles developed over the past decades. Cooper’s CS4 (Figure #1) premium broadline tire was chosen as the control tire for this program. For Cooper to achieve the goals of this project, the development of multiple technologies was necessary. Six technologies were chosen that are not currently being used in the tire industry at any significant level, but that showed excellent prospects in preliminary research. This development was divided into two phases. Phase I investigated six different technologies as individual components. Phase II then took a holistic approach by combining all the technologies that showed positive results during phase one development.

    This paper analyses the role of official development assistance (ODA) in the evolution of Technological Innovation Systems (TISs) of improved cookstoves in Kenya and Rwanda. Functionally balanced TISs are central to the diffusion of new technologies and practices. We find that ODA has significantly influenced major innovation activities related to improved cookstoves in both Kenya and Rwanda over the last 30 years. However, donors’ funding has been focused mainly on the development and diffusion of technical knowledge. We find that this pattern of ODA support has not fostered balanced and effective Technology Innovation Systems, and that this has contributed to the failure to achieve widespread diffusion of improved cookstoves. We develop a quasi-evolutionary model for the long-term and systematic ODA support of innovation systems to build sustainable renewable energy TISs in developing countries. - Highlights: • We report the role of aid in the evolution of cookstove innovation systems in Kenya and Rwanda. • We show that aid was mainly focused on two functions over time, overlooking other functions • Aid has failed to foster the development of balanced innovation systems in the studied cases. • This is associated with low level of diffusion of improved cookstoves in Kenya and Rwanda. • A conceptual proposal for effective aid interventions is provided.

    This study identified the personal characteristics that affect Chilean health care providers' readiness to adopt HIV Oral Rapid Testing (ORT) in Chile as a new clinical evidence-based practice (EBP). Using a cross-sectional research design, the study sampled 150 nurses, midwives, and physicians employed at four clinics within the Pontifícia Universidad Católica de Chile Health Network in Santiago. Participants completed a self-administered survey asking about their demographic background, EBP attitudes and experience, personal beliefs related to HIV, the importance of HIV testing, and perceived self-comfort in performing a rapid HIV test. Of the participants, 90% believed that incorporating ORT would make a positive difference in their practice and said that they would be willing to adopt the technology for that reason. Nonetheless, the providers reported a mean "readiness to implement ORT" score of 15.1 out of a possible value of 20, suggesting only moderate self-perceived readiness to adopt the EBP. Education, beliefs about evidence-based practice, perceived comfort in performing ORT, and perceived importance of HIV testing explained 43.6% of the variance in readiness to adopt ORT. The findings of this first ORT pre-implementation study in Chile can help guide policy makers and HIV stakeholders to prepare for and increase primary health care providers' readiness to successfully adopt this evidence-based technology. Successful adoption of ORT could increase Chile's capacity to reach HIV-vulnerable Chileans for testing and referral to care if infected, thus helping the country to reduce further transmission of the virus and its medical complications.

  19. Why Promote Improved Fallows as a Climate-Smart Agroforestry Technology in Sub-Saharan Africa?

    Full Text Available In the literature, a lot is discussed about how agroforestry can achieve the mitigation, adaptation and productivity goals of climate-smart agriculture (CSA. However, this may be relatively too broad to assess the trade-offs and synergies of how specific agroforestry technologies or practices achieve the three pillars of CSA. Here, we provide an overview of how improved fallows (an agroforestry technology consisting of planting mainly legume tree/shrub species in rotation with cultivated crops may achieve the goals of climate-smart agriculture in Sub-Saharan Africa (SSA. Our review showed that improved fallow systems have real potential to contribute to food security and climate change mitigation and adaptation in SSA. Under proper management, improved fallows can increase maize yields to about 6 t ha−1, which is comparable to conventional maize yields under fertilization. This is attributed to improved soil fertility and nutrient use efficiency. Although data was generally limited, the growing literature showed that improved fallows increased soil carbon sequestration and reduced greenhouse emissions. Further, as a multiple output land use system, improved fallows may increase fodder availability during dry periods and provide substantial biomass for charcoal production. These livelihood options may become important financial safety nets during off seasons or in the event of crop failures. This notwithstanding, the adoption of improved fallows is mainly in Southern and Eastern Africa, where over 20,000 farmers are now using Sesbania sesban, Tephrosia vogelii, and Cajanus cajan in two-year fallows followed by maize rotations. Land tenure issues, lack of social capital, and improved germplasm and accessions of fallow species have been cited as constraints to scaling up. However, development of seed orchards, nursery development, and the willingness of policy makers to create a policy environment that addresses market failures and alleviates

    The 2012 World Health Assembly Global Vaccine Action Plan called for global access to new vaccines within 5 years of licensure. Current approaches have proven insufficient to achieve sustainable vaccine pricing within such a timeline. Paralleling the successful strategy of generic competition to bring down drug prices, a clear consensus is emerging that market entry of multiple suppliers is a critical factor in expeditiously bringing down prices of new vaccines. In this context, key target objectives for improving access to new vaccines include overcoming intellectual property obstacles, streamlining regulatory pathways for biosimilar vaccines, and reducing market entry timelines for developing-country vaccine manufacturers by transfer of technology and know-how. I propose an intellectual property, technology, and know-how bank as a new approach to facilitate widespread access to new vaccines in low- and middle-income countries by efficient transfer of patented vaccine technologies to multiple developing-country vaccine manufacturers.

    Identifying the ancestral components of genomes of admixed individuals helps uncovering the genetic basis of diseases and understanding the demographic history of populations. We estimate local ancestry on 313 Chileans and assess the contribution from three continental populations. The distribution of ancestry block-length suggests an average admixing time around 10 generations ago. Sex-chromosome analyses confirm imbalanced contribution of European men and Native-American women. Previously known genes under selection contain SNPs showing large difference in allele frequencies. Furthermore, we show that assessing ancestry is harder at SNPs with higher recombination rates and easier at SNPs with large difference in allele frequencies at the ancestral populations. Two observations, that African ancestry proportions systematically decrease from North to South, and that European ancestry proportions are highest in central regions, show that the genetic structure of Chileans is under the influence of a diffusion process leading to an ancestry gradient related to geography.

    2002-01-01

    The Chilean health care system has been intensively reformed in the past 20 years. Reforms under the Pinochet government (1973-1990) aimed mainly at the decentralization of the system and the development of a private sector. Decentralization involved both a deconcentration process and the devolution of primary health care to municipalities. The democratic governments after 1990 chose to preserve the core organization but introduced reforms intended to correct the system's failures and to increase both efficiency and equity. The present article briefly explains the current organization of the Chilean health care system. It also reviews the different reforms introduced in the past 20 years, from the Pinochet regime to the democratic governments. Finally, a brief discussion describes the strengths and weaknesses of the system, as well as the challenges it currently faces.

    To examine food advertising aimed at childhood's audience broadcast on Chilean television. Cross-sectional study. Food advertising broadcast by 4 open signal TV channels was recorded for 12 hours daily on twelve days randomly selected. Notices were classified according to food groups and level of processing. The frequency of food advertisement aimed to childhood audience was compared with those for adults. Nutrient profile of foods advertised was described. In 144 hours of recording appeared 530 food advertisement; 53.2% were aimed to childhood audience. The most advertised foods were sugary dairy (28.4%), sweetened beverages (25.5%), and sweetened cereals (17.7%). Of the foods advertised to childhood audience, 75% exceeds the criterion for free sugars. Chilean television advertises ultra-processed foods that exceed the limits of free sugars.

  9. Navigating the limitations of energy poverty: Lessons from the promotion of improved cooking technologies in Kenya

    International Nuclear Information System (INIS)

    Sesan, Temilade

    2012-01-01

    Energy poverty has been defined as the lack of access of households in developing countries to modern energy sources, and their consequent reliance on solid biomass fuels for cooking. Improved stoves have been promoted by development actors since the 1970s to alleviate various environmental and health problems associated with biomass use, with largely disappointing outcomes. Against this background, this paper examines the intervention of an international development organisation – Practical Action – in West Kochieng, Kenya, where the organisation's energy poverty alleviation efforts are aimed at addressing the health hazards of biomass smoke with six ‘low-cost’ improved cooking technologies. The study reveals that the cooking technology most valued by poor West Kochieng households is the one which most reflects their priorities, rather than those expressed by Practical Action. The findings point to three aspects of appropriateness of energy poverty alleviation interventions – technological, economic and cultural – which combine to influence acceptance and uptake of such interventions. The evidence highlights some of the limitations inherent in the generic policy recommendation to ‘leapfrog’ towards the resolution of energy poverty-related problems, and suggests that more measured steps which respond to the socio-economic realities of poor households are likely to engender more appropriate solutions. - Highlights: ► The technological, economic, and cultural appropriateness of stoves influence uptake. ► Appropriate energy technologies take cognisance of the limitations of poverty. ► Such technologies are more likely to be adopted by biomass-reliant poor households. ► Energy poverty cannot be isolated from the broader context of poverty. ► Eliminating poverty is a prerequisite to alleviating energy poverty.

    In the following paper, we present an industry perspective of inertial sensors for navigation purposes driven by applications and customer needs. Microelectromechanical system (MEMS) inertial sensors have revolutionized consumer, automotive, and industrial applications and they have started to fulfill the high end tactical grade performance requirements of hybrid navigation systems on a series production scale. The Fiber Optic Gyroscope (FOG) technology, on the other hand, is further pushed into the near navigation grade performance region and beyond. Each technology has its special pros and cons making it more or less suitable for specific applications. In our overview paper, we present latest improvements at NG LITEF in tactical and navigation grade MEMS accelerometers, MEMS gyroscopes, and Fiber Optic Gyroscopes, based on our long-term experience in the field. We demonstrate how accelerometer performance has improved by switching from wet etching to deep reactive ion etching (DRIE) technology. For MEMS gyroscopes, we show that better than 1°/h series production devices are within reach, and for FOGs we present how limitations in noise performance were overcome by signal processing. The paper also intends a comparison of the different technologies, emphasizing suitability for different navigation applications, thus providing guidance to system engineers.

    2018-03-01

    The lack of land ownership can discourage agricultural technology adoption, yet there is scarce evidence of the impact of land rental contracts on the adoption of improved crop varieties in developing countries. The current study investigates such impact using a nationally representative survey of Ethiopian maize farmers. In contrast to many previous studies, we show in a simple model that cash-renters are as likely to adopt improved maize varieties as owner-operators, while sharecroppers are more likely to adopt given that such varieties are profitable. Empirical analysis reveals a significant impact of sharecropping on improved maize variety adoption, and no significant impact from cash-rental, lending support to the above hypotheses. These results imply that improvements in land rental markets can potentially enhance household welfare through crop variety adoption in agrarian economies where land sales markets are incomplete or missing.

    To investigate if socio-demographic factors, religiosity, HIV-related knowledge, Marianismo, history of having been tested for HIV, knowing someone who died of AIDS and HIV risk perception were predictive factors to HIV enacted stigma predictors among Chilean women. HIV infection is the number one cause of death among women during their reproductive years. In Chile, studies with people living with HIV demonstrate the existence of HIV-related stigma. However, limited evidence is available about the underlying causes of HIV enacted stigma that results in stigmatisation and discrimination. The current cross-sectional study is a secondary analysis of data collected to assess the impact of an HIV prevention intervention (Mano a Mano-Mujer) designed for Chilean women. A quasi-experimental design was used in the original study. This study was conducted in two communities in Santiago, Chile. The sample for this study consisted of 496 Chileans between ages 18-49. Descriptive statistics and multiple regression were used for the analysis. Participants in the study reported high levels (77·8%) of HIV enacted stigma. Higher levels of HIV-related knowledge were associated with lower levels of HIV enacted stigma. Women with higher education had lower levels of HIV enacted stigma than women with elementary education. In addition, greater levels of marianismo (cultural belief that women should be passive, faithful, and devoted to family) were associated with higher HIV enacted stigma scores. The findings reflected the presence of HIV enacted stigma among Chilean women. Identifying the significant predictors of HIV enacted stigma can help the nursing community to design HIV prevention interventions that include the reduction in HIV enacted stigma. HIV evidence-based prevention interventions should incorporate contents related to stigma to contribute to prevent HIV enacted stigma at individual and community levels in accordance with the bioecological model.

    2013-02-01

    Methods for conducting dietary assessment in the United States date back to the early twentieth century. Methods of assessment encompassed dietary records, written and spoken dietary recalls, FFQ using pencil and paper and more recently computer and internet applications. Emerging innovations involve camera and mobile telephone technology to capture food and meal images. This paper describes six projects sponsored by the United States National Institutes of Health that use digital methods to improve food records and two mobile phone applications using crowdsourcing. The techniques under development show promise for improving accuracy of food records.

    The purpose of this quality improvement initiative was to improve the utilization of continuous lateral rotation therapy (CLRT) in a nine-bed community hospital ICU within the context of a nurse-driven protocol. Nursing focus groups, analyzed using a strength, weakness, opportunity, threat (SWOT) approach, resulted in the implementation of four interventions over seven weeks. Change management strategies guided all aspects of the project. Results showed a modest increase in the utilization of CLRT. This initiative demonstrates that change management strategies may assist with the incorporation of technology into nursing practice by increasing empowerment and creating an attachment to and responsibility for outcomes.

    Co-Processing refers to the combined processing of coal and petroleum-derived heavy oil feedstocks. The coal feedstocks used are those typically utilized in direct coal liquefaction: bituminous, subbituminous, and lignites. Petroleum-derived oil, is typically a petroleum residuum, containing at least 70 W% material boiling above 525{degrees}C. The combined coal and oil feedstocks are processed simultaneously with the dual objective of liquefying the coal and upgrading the petroleum-derived residuum to lower boiling (<525{degrees}C) premium products. HTI`s investigation of the Co-Processing technology has included work performed in laboratory, bench and PDU scale operations. The concept of co-processing technology is quite simple and a natural outgrowth of the work done with direct coal liquefaction. A 36 month program to evaluate new process concepts in coal-oil coprocessing at the bench-scale was begun in September 1994 and runs until September 1997. Included in this continuous bench-scale program are provisions to examine new improvements in areas such as: interstage product separation, feedstock concentrations (coal/oil), improved supported/dispersed catalysts, optimization of reactor temperature sequencing, and in-line hydrotreating. This does not preclude other ideas from DOE contracts and other sources that can lead to improved product quality and economics. This research work has led to important findings which significantly increased liquid yields, improved product quality, and improved process economics.

    Soil acidification is an important factor that restricts the yield and quality of fruits. In this study, the comprehensive improving technologies were applied on the vineyards in which the soil pH is below 5.5. The technologies include application of soil conditioner, organic fertilizer and bacterial manure, and growth of green manure and natural grass. The results show that the comprehensive improving technologies can raise the pH of 0-15 cm soil layer by 0.5-0.8 unit and the pH of 15-30 cm soil layer by 0.3-0.6 unit. The soil bulk densities are decreased by 0.77-10.42%. The contents of organic matter, total N, available P and K in the soils are all increased. Therefore, the soil fertilities are improved. The yields of grape fruits are increased by 12.77-14.94%, and the contents of soluble solid in the grapes are raised by 7.01-9.55%, by the comprehensive measure of seaweed liquid silicon plus sheep manure plus growth of green manure. The comprehensive measure of soil conditioner Naduoli No. 1 plus bacterial manure plus natural grass increases the yields of grape by 7.67%, raises the content of soluble solid in the grape by 8.6%. But the effect of the comprehensive measure of unslaked lime plus sheep manure plus growth of green manure is not clear.

    2011-01-01

    The past oil crises have caused dramatic improvements in fuel efficiency in all industrial sectors. The aviation sector—aircraft manufacturers and airlines—has also made significant efforts to improve the fuel efficiency through more advanced jet engines, high-lift wing designs, and lighter airframe materials. However, the innovations in energy-saving aircraft technologies do not coincide with the oil crisis periods. The largest improvement in aircraft fuel efficiency took place in the 1960s while the high oil prices in the 1970s and on did not induce manufacturers or airlines to achieve a faster rate of innovation. In this paper, we employ a historical analysis to examine the socio-economic reasons behind the relatively slow technological innovation in aircraft fuel efficiency over the last 40 years. Based on the industry and passenger behaviors studied and prospects for alternative fuel options, this paper offers insights for the aviation sector to shift toward more sustainable technological options in the medium term. Second-generation biofuels could be the feasible option with a meaningful reduction in aviation’s lifecycle environmental impact if they can achieve sufficient economies of scale. PMID:22016716

    2003-03-01

    Plant-based complementary foods are the main source of nutrients for many young children in developing countries. They may, however, present problems in providing nutritionally adequate and safe diets for older infants and young children. The high starch content leads to low-nutrient diets that are bulky and dense, with high levels of antinutritive factors such as phytates, tannins, lectins, and enzyme inhibitors. Phytates impair mineral bioavailability, lectins interfere with intestinal structure, and enzyme inhibitors inhibit digestive enzymes. In addition, there is often microbial contamination, which leads to diarrhea, growth-faltering, and impaired development, and the presence of chemical contaminants may lead to neurological disease and goiter. The fact that some fruits containing carotenoids are only available seasonally contributes to the vulnerability of children receiving predominantly plant-based diets. Traditional household food technologies have been used for centuries to improve the quality and safety of complementary foods. These include dehulling, peeling, soaking, germination, fermentation, and drying. While modern communities tend to reject these technologies in favor of more convenient fast-food preparations, there is now a resurgence of interest in older technologies as a possible means of improving the quality and safety of complementary foods when the basic diet cannot be changed for economic reasons. This paper describes the biology, safety, practicability, and acceptability of these traditional processes at the household or community level, as well as the gaps in research, so that more effective policies and programs can be implemented to improve the quality and safety of complementary foods.

    2015-11-01

    Social housing organisations are increasingly installing renewable energy technologies, particularly for the provision of heating and hot water. To meet carbon reduction targets, uptake and installation must allow occupants to use the technology effectively. This paper describes research which investigated the service of installing heat pumps into UK social housing properties, from both landlords' and tenants' experiences. Adopting a user centred design approach, the research was in three phases: an exploration study to investigate landlords' and tenants' experiences of heat pump installation and use; refinement and development of the requirements for improved service delivery, primarily technology introduction and control; and the development and initial evaluation of an information leaflet as a key touchpoint in the service delivery. Recommendations for improved service delivery, to enable heat pumps to be accepted and used more effectively, are presented, as well as reflection on the process of applying user centred design in this context. In a relatively immature area of industry, installations to date have been heavily focused on technical aspects. This paper provides an insight into the human aspects of the service delivery of heat pumps in social housing, providing designers and social housing landlords with insight about how to improve the service.

    Targetrons are mobile group II introns that can recognize their DNA target sites by base-pairing RNA-DNA interactions with the aid of site-specific binding reverse transcriptases. Targetron technology stands out from recently developed gene targeting methods because of the flexibility, feasibility, and efficiency, and is particularly suitable for the genetic engineering of difficult microorganisms, including cellulolytic bacteria that are considered promising candidates for biomass conversion via consolidated bioprocessing. Along with the development of the thermotargetron method for thermophiles, targetron technology becomes increasingly important for the metabolic engineering of industrial microorganisms aiming at biofuel/chemical production. To summarize the current progress of targetron technology and provide new insights on the use of the technology, this paper reviews the retrohoming mechanisms of both mesophilic and thermophilic targetron methods based on various group II introns, investigates the improvement of targetron tools for high target efficiency and specificity, and discusses the current applications in the metabolic engineering for bacterial producers. Although there are still intellectual property and technical restrictions in targetron applications, we propose that targetron technology will contribute to both biochemistry research and the metabolic engineering for industrial productions.

    2017-12-01

    Precipitation deficit is traditionally considered as the main driver of drought events, however the evolution of drought conditions is also influenced by other variables such as temperature, wind speed and evapotranspiration. In view of global warming, the effect of rising temperatures may lead to increased socio-economic drought impacts, particularly in vulnerable developing countries. In this work, we used two drought indices to analyze the impacts of precipitation and temperature on the frequency, severity and duration of Chilean droughts (25°S-56°S) during the XXI century, using multi-model climate projections consistent with the high-end RCP 8.5 scenario. An ensemble of seven global CMIP5 simulations were used to drive the Earth System Model EC-EARTH3-HR v3.1 over the 1976-2100 period, in order to increase the spatial resolution from the original grid to 0.35°. The Standardized Precipitation Index (SPI) was used to describe the impact of precipitation on drought conditions, while the Standardized Precipitation-Evapotranspiration Index (SPEI) was used to assess the effect of temperature -throughout changes in potential evapotranspiration- on drought characteristics at different time scales. Drought indices along with duration, severity and frequency of drought events were computed for a 30-year baseline period (1976-2005) and then compared to three 30-year periods representing short, medium and long-term scenarios (2011-2040, 2041-2070 and 2071-2100). Indices obtained from climate simulations during the baseline period were compared against the corresponding values derived from ground observations. Results obtained with SPI-12 reveal a progressive decrease in precipitation in Chile, which is consistent through all climate models, though each of them shows a different spatial pattern. Simulations based on SPEI-12 show that the expected increase in evaporative demand (driven by the temperature increase) for the region is likely to exacerbate the severity and

  18. Modeling the impact of improved aircraft operations technologies on the environment and airline behavior

    Science.gov (United States)

    Foley, Ryan Patrick

    The overall goal of this thesis is to determine if improved operations technologies are economically viable for US airlines, and to determine the level of environmental benefits available from such technologies. Though these operational changes are being implemented primarily with the reduction of delay and improvement of throughput in mind, economic factors will drive the rate of airline adoption. In addition, the increased awareness of environmental impacts makes these effects an important aspect of decision-making. Understanding this relationship may help policymakers make decisions regarding implementation of these advanced technologies at airports, and help airlines determine appropriate levels of support to provide for these new technologies. In order to do so, the author models the behavior of a large, profit-seeking airline in response to the introduction of advanced equipage allowing improved operations procedures. The airline response included changes in deployed fleet, assignment of aircraft to routes, and acquisition of new aircraft. From these responses, changes in total fleet-level CO2 emissions and airline profit were tallied. As awareness of the environmental impact of aircraft emissions has grown, several agencies (ICAO, NASA) have moved to place goals for emissions reduction. NASA, in particular, has set goals for emissions reduction through several areas of aircraft technology. Among these are "Operational Improvements," technologies available in the short-term through avionics and airport system upgrades. The studies in this thesis make use of the Fleet-Level Environmental Evaluation Tool (FLEET), a simulation tool developed by Purdue University in support of a NASA-sponsored research effort. This tool models the behavior of a large, profit-seeking airline through an allocation problem. The problem is contained within a systems dynamics type approach that allows feedback between passenger demand, ticket price, and the airline fleet composition

  19. Evolution of Technology for Continuous Renal Replacement Therapy: Forty Years of Improvement.

    Science.gov (United States)

    Ronco, Claudio

    2018-01-01

    Continuous arteriovenous hemofiltration (CAVH) was proposed in 1977 as an alternative treatment for acute renal failure in patients in whom peritoneal dialysis or hemodialysis was clinically or technically precluded. In the mid-1980s, this technique was extended to infants and children. CAVH presented important advantages in the areas of hemodynamic stability, control of circulating volume, and nutritional support. However, there were serious shortcomings such as the need for arterial cannulation and limited solute clearance. These problems were solved by the introduction of continuous arteriovenous hemodiafiltration and continuous arteriovenous hemodialysis, where uremic control could be achieved by increasing countercurrent dialysate flow rates to 1.5 or 2 L/h as necessary, or by venovenous techniques utilizing a double-lumen central venous catheter for vascular access. Thus, continuous venovenous hemofiltration replaced CAVH because of its improved performance and safety. From the initial adoptive technology, specific machines have been designed to permit safe and reliable performance of the therapy. These new machines have progressively undergone a series of technological steps that have resulted in the evolution of highly sophisticated equipment utilized today. A significant number of advances have taken place since the time continuous renal replacement therapy was initiated. In particular, there have been successful experiments with high-volume hemofiltration and high-permeability hemofiltration. The additional and combined use of sorbent has also been tested successfully. Progress has been made in the technology as well as the understanding of the pathophysiology of acute kidney injury. Today, new biomaterials and new devices are available and new frontiers are on the horizon. Although improvements have been made, a lot remains to be done. Critical care nephrology is expected to further evolve in the near future, especially in the area of information and

  20. Modern technologies for improving cleaning and disinfection of environmental surfaces in hospitals

    2016-04-01

    Full Text Available Abstract Experts agree that careful cleaning and disinfection of environmental surfaces are essential elements of effective infection prevention programs. However, traditional manual cleaning and disinfection practices in hospitals are often suboptimal. This is often due in part to a variety of personnel issues that many Environmental Services departments encounter. Failure to follow manufacturer’s recommendations for disinfectant use and lack of antimicrobial activity of some disinfectants against healthcare-associated pathogens may also affect the efficacy of disinfection practices. Improved hydrogen peroxide-based liquid surface disinfectants and a combination product containing peracetic acid and hydrogen peroxide are effective alternatives to disinfectants currently in widespread use, and electrolyzed water (hypochlorous acid and cold atmospheric pressure plasma show potential for use in hospitals. Creating “self-disinfecting” surfaces by coating medical equipment with metals such as copper or silver, or applying liquid compounds that have persistent antimicrobial activity surfaces are additional strategies that require further investigation. Newer “no-touch” (automated decontamination technologies include aerosol and vaporized hydrogen peroxide, mobile devices that emit continuous ultraviolet (UV-C light, a pulsed-xenon UV light system, and use of high-intensity narrow-spectrum (405 nm light. These “no-touch” technologies have been shown to reduce bacterial contamination of surfaces. A micro-condensation hydrogen peroxide system has been associated in multiple studies with reductions in healthcare-associated colonization or infection, while there is more limited evidence of infection reduction by the pulsed-xenon system. A recently completed prospective, randomized controlled trial of continuous UV-C light should help determine the extent to which this technology can reduce healthcare-associated colonization and infections

  1. Catalytic Pyrolysis of Chilean Oak: Influence of Brønsted Acid Sites of Chilean Natural Zeolite

    Directory of Open Access Journals (Sweden)

    Serguei Alejandro Martín

    2017-11-01

    Full Text Available This paper proposes the Chilean natural zeolite as catalyst on bio-oil upgrade processes. The aim of this study was to analyze chemical composition of bio-oil samples obtained from catalytic pyrolysis of Chilean native oak in order to increase bio-oil stability during storage. In order to identify chemical compounds before and after storage, biomass pyrolysis was carried out in a fixed bed reactor at 623 K and bio-oil samples were characterized by gas chromatography/mass spectrophotometry (GC/MS. A bio-oil fractionation method was successfully applied here. Results indicate that bio-oil viscosity decreases due to active sites on the zeolite framework. Active acids sites were associated with an increment of alcohols, aldehydes, and hydrocarbon content during storage. Higher composition on aldehydes and alcohols after storage could be attributed to the occurrence of carbonyl reduction reactions that promotes them. These reactions are influenced by zeolite surface characteristics and could be achieved via the direct contribution of Brønsted acid sites to Chilean natural zeolite.

  2. Price and access charge discrimination in electricity distribution: an application to the Chilean case

    International Nuclear Information System (INIS)

    Raineri, R.; Giaconi, P.

    2005-01-01

    This paper presents and analyzes a model of electricity distribution in Chile with three alternative regulatory pricing contract schemes for assigning a common capacity cost to final customers and competitive energy sellers. The first scheme involves Ramsey Pricing, while under the second and third schemes the monopoly chooses final prices and access charges subject either to a peak-load Physical Cap or a total revenue Price Cap constraint. In addition, we consider circumstances in which the regulator does not know consumer demand, the monopoly cannot price discriminate beyond a range defined by the marginal cost as a floor and the stand-alone cost as a ceiling, and access charges are set at the fully distributed cost allocation level currently in force. The model is calibrated with Chilean data, and demonstrates that in terms of social welfare the fully distributed cost contract scheme currently in effect can be improved by discriminatory pricing complemented by certain of the analyzed constraints.

  3. Can Handheld Thermal Imaging Technology Improve Detection of Poachers in African Bushveldt?

    Directory of Open Access Journals (Sweden)

    Adam G Hart

    Full Text Available Illegal hunting (poaching is a global threat to wildlife. Anti-poaching initiatives are making increasing use of technology, such as infrared thermography (IRT, to support traditional foot and vehicle patrols. To date, the effectiveness of IRT for poacher location has not been tested under field conditions, where thermal signatures are often complex. Here, we test the hypothesis that IRT will increase the distance over which a poacher hiding in African scrub bushveldt can be detected relative to a conventional flashlight. We also test whether any increase in effectiveness is related to the cost and complexity of the equipment by comparing comparatively expensive (22,000 USD and relatively inexpensive (2000 USD IRT devices. To test these hypotheses we employ a controlled, fully randomised, double-blind procedure to find a poacher in nocturnal field conditions in African bushveldt. Each of our 27 volunteer observers walked three times along a pathway using one detection technology on each pass in randomised order. They searched a prescribed search area of bushveldt within which the target was hiding. Hiding locations were pre-determined, randomised, and changed with each pass. Distances of first detection and positive detection were noted. All technologies could be used to detect the target. Average first detection distance for flashlight was 37.3 m, improving by 19.8 m to 57.1 m using LIRT and by a further 11.2m to 68.3m using HIRT. Although detection distances were significantly greater for both IRTs compared to flashlight, there was no significant difference between LIRT and HIRT. False detection rates were low and there was no significant association between technology and accuracy of detection. Although IRT technology should ideally be tested in the specific environment intended before significant investment is made, we conclude that IRT technology is promising for anti-poaching patrols and that for this purpose low cost IRT units are as

    Plant reliability and safety hinges on the proper functioning of several valves. Recent advancements in valve technology have resulted in new analytical and test methods for evaluating and improving valve and actuator reliability. This is especially significant in critical service applications in which the economic impact of a valve failure on production, outage schedules and consequential damages far surpasses the initial equipment purchase price. This paper presents an overview of recent advances in valve technology driven by reliability concerns and cost savings objectives without comprising safety in the Nuclear Power Industry. This overview is based on over 27 years of experience in supporting US and International nuclear power utilities, and contributing to EPRI, and NSSS Owners' Groups in developing generic models/methodologies to address industry wide issues; performing design basis reviews; and implementing plant-wide valve reliability improvement programs. Various analytical prediction software and hardware solutions and training seminars are now available to implement valve programs covering power plants' lifecycle from the construction phase through life extension and power up rate. These tools and methodologies can enhance valve-engineering activities including the selection, sizing, proper application, condition monitoring, failure analysis, and condition based maintenance optimization with a focus on potential bad actors. This paper offers two such examples, the Kalsi Valve and Actuator Program (KVAP) and Check Valve Analysis and Prioritization (CVAP) [1-3, 8, 9, 11-13]. The advanced, validated torque prediction models incorporated into KVAP software for AOVs and MOVs have improved reliability of margin predictions and enabled cost savings through elimination of unwarranted equipment modifications. CVAP models provides a basis to prioritize the population of valves recommended for preventive maintenance, inspection and/or modification, allowing

    1997-06-01

    In response to a formal request by the Group of 77 and China, the United Nations Industrial Development Organization (UNIDO) initiated a study to identify opportunities to reduce the emissions of greenhouse gases from energy-intensive industries in developing countries. These sectors currently include iron and steel, petroleum refining, cement, paper and pulp and nitrogen fertilizers. The aim of this first phase was to describe: how energy is used in the energy-intensive industries in developing countries today; what current trends indicate for the future; the potential contribution of improved technologies and practices to moving toward more sustainable industrial production in developing countries, and to provide developing countries with an analytical tool for evaluating opportunities to limit industrial greenhouse-gas (GHG) emissions in their industrial sectors through the transfer of improved technologies and processes. The immediate objectives of Phase 1 were twofold: to provide information to developing countries in the form of an inventory of energy-efficient, best-available technologies and processes that can be used to abate greenhouse-gas emissions in the most energy-intensive industrial sub-sectors as well as cross-cutting measures applicable in a range of sub-sectors, and; to provide an analytical methodology in the form of a software tool that enables the user to evaluate and compare the costs, energy requirements, and greenhouse-gas emissions associated with scenarios of specific technology and process options. To meet these objectives, the first phase of the study comprised: a Report entitled Industrial Greenhouse-gas Emissions from Developing Countries; a Software Package containing, an Industrial Technology Inventory, and an Analysis Tool, and; Industry/country-specific Case Studies. The Report describes current energy use and greenhouse-gas emissions in energy-intensive industries in developing countries, and similar industries exemplifying good

    Full Text Available With the development of educational technology, the concept of technology-enhanced multimedia instructions is using widely in the educational settings. Technology can be employed in teaching different skills such as listening, reading, speaking and writing. Among these skills, reading comprehension is the skill in which EFL learners have some problems to master. Regarding this issue, the present study aimed at investigating the effect of video materials on improving reading comprehension of Iranian intermediate EFL learners. A Longman Placement Test was administered to 30 EFL learners to ensure that learners are at the same level of proficiency. The students were chosen from the state high schools in Chabahar.  The participants were regarded as intermediate learners and were divided into two groups (one experimental group and one control group. Then, a pre-test of reading comprehension was administered to assess the participants’ reading comprehension. The participants of experimental group used video files to improve their reading comprehension while the control group received conventional approaches of teaching reading comprehension. Finally, all the participants were assigned a 40-item multiple-choice reading comprehension post-test.

    2015-07-01

    Today, almost 3 billion people in developing countries rely on biomass as primary cooking fuel, with profound negative implications for their well-being. Improved biomass cooking stoves are alleged to counteract these adverse effects. This paper evaluates take-up and impacts of low-cost improved stoves through a randomized controlled trial. The randomized stove is primarily designed to curb firewood consumption, but not smoke emissions. Nonetheless, we find considerable effects not only on firewood consumption, but also on smoke exposure and, consequently, smoke-related disease symptoms. The reduced smoke exposure results from behavioural changes in terms of increased outside cooking and a reduction in cooking time. We conclude that in order to assess the effectiveness of a technology-oriented intervention, it is critical to not only account for the incidence of technology adoption - the extensive margin - but also for the way the new technology is used - the intensive margin.

    Full Text Available Vegetable production, including that of chillies, plays an important role in agricultural sector and rural economic development worldwide. This is because of greater farm productivity with regard to vegetables than cereal and staple crops. This paper analyses the impact of seed technology development on the economic aspects of chilli production in Central Java. Particular attention is paid to improved varieties of chilli. Potential consequences of seed technology development are discussed. Data of this study are compiled from surveys conducted in three selected chilli producing regions in 2010-2012. The results show that the major varieties of chilli grown by surveyed farmers are grouped into three broad types: hybrids, local and improved open pollinated varieties. The chilli varieties farmers selected varied according to location and cropping season. In the dry season, farmers grew similar proportions of hybrid, local, and open pollinated types. Nevertheless, there were differences among the survey sites. Farmers grew different varieties to exploit seasonal microclimates and market preferences. Mostly, farmers selected varieties for economic motives. The consequence of growing hybrids was less use of agrochemicals, particularly pesticides, than for other varieties. Overall, they show the best economic performance in the study site. Development of seed technology should consider agro-ecological and economic aspects to obtain better outcomes. Private sector and national research institutions need to collaborate more to utilise available genetic resources to produce better varieties of chilli.

    2014-01-01

    This study analyzes energy intensity trends and drivers in 40 major economies using the WIOD database, a novel harmonized and consistent dataset of input–output table time series accompanied by environmental satellite data. We use logarithmic mean Divisia index decomposition to (1) attribute efficiency changes to either changes in technology or changes in the structure of the economy, (2) study trends in global energy intensity between 1995 and 2007, and (3) highlight sectoral and regional differences. For the country analysis we apply the traditional two factor index decomposition approach, while for the global analysis we use a three factor decomposition which includes the consideration of regional structural changes in the global economy. We first show that heterogeneity within each sector across countries is high. These general trends within sectors are dominated by large economies, first and foremost the United States. In most cases, heterogeneity is lower within each country across the different sectors. Regarding changes of energy intensity at the country level, improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries. Notable exceptions are Japan, the United States, Australia, Taiwan, Mexico and Brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction. At the global level we find that despite a shift of the global economy to more energy-intensive countries, aggregate energy efficiency improved mostly due to technological change

    During year 2011 two outbreaks of Salmonella infection captured media attention in the Metropolitan Area (MA) in Chile: one of typhoid fever associated to Salmonella serotype Typhi, and the other, of gastroenteritis related to Salmonella serotype Enteritidis, both with decreasing or stable rates in the previous years. The aim of this work is to analyze probable causes of their reemergence. Several government websites were searched looking for epidemiological data. Typhoid fever rates have declined to current values of 1 case per 100.000 habitants, a decreased associated to improvements in the human development index. The typhoid outbreak was associated to a predominant clone within the MA. The only risk factor identified was consumption of raw vegetables acquired in open fairs, but without identifying a common source. Despite improvements in disease notification and molecular epidemiology capabilities, this outbreak is coincidental with a reduced number of food inspection visits in the MA, probably explained by the limited personnel available for this task. In the case of Salmonella Enteritidis, rates have increased twice since 1998 (5.3 to 10.7 per 100.000 habitants) with an important increase in the number of outbreaks linked to this agent (7 to 31 annual outbreaks) since year 2005. Persistence of this problem is probably associated to the low surveillance of poultry farms made by the Chilean state, to the absence of a cold chain during collection, distribution and selling of eggs, and to the lack of an educational program directed to the population. The recent regulation that bans home-made mayonnaise in restaurant or fast food stores is an important advance that requires further evaluation. The persistence and reemergence of different kind of Salmonellosis in Chile suggests chronic problems on the size and role of the Chilean state regarding food safety.

    2011-02-01

    Solid dosage form manufacture still remains the most common in the production of pharmaceutical products. Established granulation processes can benefit from novel technical improvements, which can in turn enhance the behavior and properties of the process intermediates, that is, granules. These improvements in the manufacturing process can ultimately shorten development times, provide processing solutions for challenging materials and improve quality of drug delivery systems. The aim of this review is to give the reader an overview of the latest trends in research with regard to roller compaction technology. Pneumatic dry granulation is also discussed as a new development with the potential to improve and extend the use of dry granulation processes, which can result in a substantial contribution to drug delivery system development and drug product manufacture. Dry granulation techniques, and more specifically roller compaction, can provide many advantages over the more established wet granulation techniques. There are still problems with roller compaction such as high amounts of fines and poor flow of granulate. Technical innovations that improve existing processes will have a considerable impact on development times and contribute to improved material processability and behavior of the end product. Pneumatic dry granulation has the potential to provide such alternatives.

    Global food security demands the development and delivery of new technologies to increase and secure cereal production on finite arable land without increasing water and fertilizer use. There are several options for boosting wheat yields, but most offer only small yield increases. Wheat is an inbred plant, and hybrids hold the potential to deliver a major lift in yield and will open a wide range of new breeding opportunities. A series of technological advances are needed as a base for hybrid wheat programmes. These start with major changes in floral development and architecture to separate the sexes and force outcrossing. Male sterility provides the best method to block self-fertilization, and modifying the flower structure will enhance pollen access. The recent explosion in genomic resources and technologies provides new opportunities to overcome these limitations. This review outlines the problems with existing hybrid wheat breeding systems and explores molecular-based technologies that could improve the hybrid production system to reduce hybrid seed production costs, a prerequisite for a commercial hybrid wheat system.

    Full Text Available With the rapid development of information technology equipment and its use in the teaching and learning activities, the working environment (especially indoor air quality in which students and pupils spend a great deal of time in educational institutions has been changing. Therefore, special attention must be paid to indoor air quality and comfort. It is of great importance to maintain indoor air quality in an object, such as information technology classrooms, where a large number of students spend long periods of time. Poor indoor environment can negatively affect scholarly performances and cause discomfort and poor work performance. The problem of indoor air quality in educational institutions can be more serious than in other types of objects, because of the higher concentration of students and information technology equipment. This paper analyzes the changes in air quality in an information technology classrooms, when occupied with students, for the period from March to April. The changes of indoor air temperature, relative humidity, and carbon dioxide concentration are monitored in the classroom, as well as outdoor temperature and relative humidity. Several cases are studied: the classroom with closed windows and doors (closed classroom, the classroom with natural ventilation, the classroom cooled with a split system (cooled classroom. Responses of students are followed for each case. The analysis is performed based on the measurement results and numerical simulations using the computational fluid dynamics package, and measures are proposed to improve the indoor air quality in the considered classroom.

    The formation of deposits on the functional surfaces of the equipment of heating systems and their corrosion are one of the major energetic problems. To improve the operational efficiency of thermal power equipment, surface-active agents (surfactants) are widely used, which are applied for the treatment of the working surfaces before use, during use, to prevent the parking corrosion, as well as while performing periodic chemical cleanings of power equipment. The tests have been performed, and the technology of application of Auge Neo Ac 56 acid product (MAHIM, Kazan) has been developed, designed to remove mineral deposits and scale from cooling and boiler systems without mechanical influence on them and without disassembly of technological equipment.

  5. A Measurement Management Technology for Improving Energy Efficiency in Data Centers and Telecommunication Facilities

    2012-06-28

    Data center (DC) electricity use is increasing at an annual rate of over 20% and presents a concern for the Information Technology (IT) industry, governments, and the society. A large fraction of the energy use is consumed by the compressor cooling to maintain the recommended operating conditions for IT equipment. The most common way to improve the DC efficiency is achieved by optimally provisioning the cooling power to match the global heat dissipation in the DC. However, at a more granular level, the large range of heat densities of today's IT equipment makes the task of provisioning cooling power optimized to the level of individual computer room air conditioning (CRAC) units much more challenging. Distributed sensing within a DC enables the development of new strategies to improve energy efficiency, such as hot spot elimination through targeted cooling, matching power consumption at rack level with workload schedule, and minimizing power losses. The scope of Measurement and Management Technologies (MMT) is to develop a software tool and the underlying sensing technology to provide critical decision support and control for DC and telecommunication facilities (TF) operations. A key aspect of MMT technology is integration of modeling tools to understand how changes in one operational parameter affect the overall DC response. It is demonstrated that reduced ordered models for DC can generate, in less than 2 seconds computational time, a three dimensional thermal model in a 50 kft{sup 2} DC. This rapid modeling enables real time visualization of the DC conditions and enables 'what if' scenarios simulations to characterize response to 'disturbances'. One such example is thermal zone modeling that matches the cooling power to the heat generated at a local level by identifying DC zones cooled by a specific CRAC. Turning off a CRAC unit can be simulated to understand how the other CRAC utilization changes and how server temperature responds

    COGEMA provides uranium enrichment services to the nuclear industry worldwide. To meet general French safety requirements related to environmental protection issues, COGEMA has developed, as an extension of the enrichment operation, a facility to convert DUF 6 into a stable, fluorine-free compound. After 5 years demonstration of the process on a pilot plant, COGEMA placed a facility in industrial operation in 1984 to convert DUF 6 into stable oxide U 3 O 8 ; a second facility was commissioned in 1993, doubling the capacity. Since the beginning of its industrial de-fluorination operations, COGEMA has ever been concerned to make its technology as reliable and as cost effective as possible. Accordingly, an improvement work has been constantly under way which already benefited to the construction of the second facility, completed in 1993. This paper will give an overview of the improvement work performed over the years, relating not only to the technology (optimizing the de-fluorination output, reducing the corrosion inside the kilns, improving the uranium oxide powder compaction factor,...), but also to the process itself (hydrodynamic modeling of the process reactions inside the kiln) and maintenance issues (systematic monitoring of filters plugging, recycling of cartridge filters,...).

Use of information technology varied across physician organizations, including electronic access to laboratory test results (medical groups, 49.3%; IPAs, 19.6%), alerts for potential drug interactions (medical groups, 33.9%; IPAs, 9.5%), electronic drug prescribing (medical groups, 41.9%; IPAs, 25.1%), and physician use of e-mail with patients (medical groups, 34.2%; IPAs, 29.1%). Adoption of CIT was stronger for physician organizations evaluated by external entities for pay-for-performance and public reporting purposes (P = 0.042) and for those participating in quality improvement initiatives (P < 0.001). External incentives and participation in quality improvement initiatives are associated with greater use of CIT by large physician practices.

    Full Text Available This study was carried out to determine the welfare effects of improved maize technology in Buruku Local Government Area of Benue State, Nigeria. The study also examined the determinants of the adoption of improved maize technology. Structured questionnaires were used in collecting the primary data for the study. A multi-stage random technique was used in selecting 125 farm households for the study. The Logit and ordinary least square (OLS models were used in analyzing the data. The OLS results show that adoption of improved maize varieties is positively and significantly related to household welfare and thus has contributed to moving farm households out of poverty. Other variables found to be statistically significant in explaining household welfare are education, household size, and landholding. The Logit results show that age, household size, off-farm income, and education were found to be significant in influencing farmers’ adoption decisions. Some robustness checks were performed with different specifications of the Logit and OLS models as well as re-estimation with propensity matching score approach. Overall, the results are robust to different specifications.

    Full Text Available Spinal metastases compressing the spinal cord are a medical emergency and should be operated on if possible; however, patients’ medical condition is often poor and surgical complications are common. Minimizing surgical extant, operative time, and blood loss can potentially reduce postoperative complications. This is a retrospective study describing the patients operated on in our department utilizing a minimally invasive surgery (MIS approach to decompress and instrument the spine from November 2013 to November 2014. Five patients were operated on for thoracic or lumbar metastases. In all cases a unilateral decompression with expandable tubular retractor was followed by instrumentation of one level above and below the index level and additional screw at the index level contralateral to the decompression side. Cannulated fenestrated screws were used (Longitude FNS and cement was injected to increase pullout resistance. Mean operative time was 134 minutes and estimated blood loss was minimal in all cases. Improvement was noticeable in neurological status, function, and pain scores. No complications were observed. Technological improvements in spinal instruments facilitate shorter and safer surgeries in oncologic patient population and thus reduce the complication rate. These technologies improve patients’ quality of life and enable the treatment of patients with comorbidities.

    The aim of this study was to explore and describe how client-centred occupational therapy interventions may support and improve the ability to use everyday technology (ET) in work tasks in people with acquired brain injury (ABI). A qualitative, descriptive multiple-case study was designed, and occupation-based interventions were provided to three working-age participants with ABI. Multiple sources were used to collect data throughout the three intervention processes, including assessments, field notes, and interviews. The Canadian Occupational Performance Measure and the Management of Everyday Technology Assessment were administered before the interventions, after the interventions and at a follow-up session 2-3 months subsequent to the interventions. The three intervention processes initially consisted of similar actions, but subsequently the actions took on a different focus and intensity for each case. All of the goals in each of the three case processes were achieved, and both perceived and observed abilities to use ET in work tasks improved. Client-centred occupational therapy interventions might have the potential to improve the ability to use ET in work tasks in people with ABI.

    Full Text Available The necessity of improvement of spherical articulated joints is proved on the example of a ball bearing of a forward suspension bracket of a car. The purpose of the work is to improve the design and technology of manufacturing the ball hinge of the car suspension to improve its operational capabilities by increasing the durability of the spherical tribosystem «ball finger–liner». The ways of increasing the durability of spherical articulated joints by design and technological methods were formulated. The main factors of influence on the process of wear of spherical tribosystem «finger-liner» were considered. Taking into account the existing experience and results of the conducted studies, a self-regulated ball joint with an elastic element of the original design was developed. On the basis of the kinematic scheme of sphere manufacturing, a device for turning the incomplete spherical surface of a finger of high accuracy was developed. For hardening of partial spherical surfaces by surface plastic deformation developed by static-pulse device, which provides the layer with a heterogeneous structure, required physical and mechanical properties and geometrically determined lubricant-retaining microrelief. The results of this work in future will be planned to generalize and used for the manufacture of competitive products that contains parts with incomplete spherical surfaces.

    Hand hygiene (HH) is widely regarded as the most effective preventive measure for health care-associated infection. However, there is little robust evidence on the best interventions to improve HH compliance or whether a sustained increase in compliance can reduce rates of health care-associated infection. To evaluate the effectiveness of a real-time feedback to improve HH compliance in the inpatient setting, we used a quasiexperimental study comparing the effect of real-time feedback using wireless technology on compliance with HH. The study was conducted in two 20-bed step-down units at a private tertiary care hospital. Phase 1 was a 3-month baseline period in which HH counts were performed by electronic handwash counters. After a 1-month washout period, a 7-month intervention was performed in one step-down unit while the other unit served as a control. HH, as measured by dispensing episodes, was significantly higher in the intervention unit (90.1 vs 73.1 dispensing episodes/patient-day, respectively, P = .001). When the intervention unit was compared with itself before and after implementation of the wireless technology, there was also a significant increase in HH after implementation (74.5 vs 90.1 episodes/patient-day, respectively, P = .01). There was also an increase in mean alcohol-based handrub consumption between the 2 phases (68.9 vs 103.1 mL/patient-day, respectively, P = .04) in the intervention unit. We demonstrated an improvement in alcohol gel usage via implementation of real-time feedback via wireless technology.

    Transitioning from medical school and general surgery training to cardiothoracic (CT) surgical training poses unique challenges for trainees and patient care. We hypothesized that participation in technology-enhanced simulation modules that provided early exposure to urgent/emergent CT patient problems would improve cognitive skills and readiness to manage common urgencies/emergencies. Traditional and integrated cardiothoracic residents at our institution participated in a technology-enhanced simulation curriculum. The course comprised of didactics, hands-on simulation, virtual models, and mock oral examinations. Residents also were given a validated pretest and post-test to evaluate knowledge retention and integration. Resident performance was graded using a previously validated objective structured clinical examination. Resident perception of course usefulness and relevance was determined through the completion of a perception survey. This study occurred at the University of Pittsburgh School of Medicine with the Department of Cardiothoracic Surgery. The facility used was the Peter Winter Institute for Simulation, Education and Research. From 2013 to 2015, 25 traditional and integrated cardiothoracic residents participated in these training modules who have completed all portions of the simulation were used for analysis. For our participants, knowledge base significantly increased by 7.9% (pretest = 76.0% vs. post-test = 83.9%, p technology-enhanced course combining didactics, simulation, and real-time assessment, residents demonstrated objective improvements in cognitive skills and readiness in managing CT patients. Resident postcourse feedback indicated enhanced confidence, suggesting increased preparedness transitioning to CT surgery. This has strong implications for improved patient safety during these potentially labile transition periods. Copyright © 2018 Association of Program Directors in Surgery. Published by Elsevier Inc.

    This paper reports on technology developments aimed at improving the state of the art for image-guided minimally invasive spine procedures. Back pain is a major health problem with serious economic consequences. Minimally invasive procedures to treat back pain are rapidly growing in popularity due to improvements in technique and the substantially reduced trauma to the patient versus open spinal surgery. Image guidance is an enabling technology for minimally invasive procedures, but technical problems remain that may limit the wider applicability of these techniques. The paper begins with a discussion of low back pain and the potential shortcomings of open back surgery. The advantages of minimally invasive procedures are enumerated, followed by a list of technical problems that must be overcome to enable the more widespread dissemination of these techniques. The technical problems include improved intraoperative imaging, fusion of images from multiple modalities, the visualization of oblique paths, percutaneous spine tracking, mechanical instrument guidance, and software architectures for technology integration. Technical developments to address some of these problems are discussed next. The discussion includes intraoperative computerized tomography (CT) imaging, magnetic resonance imaging (MRI)/CT image registration, three-dimensional (3-D) visualization, optical localization, and robotics for percutaneous instrument placement. Finally, the paper concludes by presenting several representative clinical applications: biopsy, vertebroplasty, nerve and facet blocks, and shunt placement. The program presented here is a first step to developing the physician-assist systems of the future, which will incorporate visualization, tracking, and robotics to enable the precision placement and manipulation of instruments with minimal trauma to the patient.

    Information and communication technology holds promise in terms of providing support and reducing isolation among older adults. We evaluated the impact of a specially designed computer system for older adults, the Personal Reminder Information and Social Management (PRISM) system. The trial was a multisite randomized field trial conducted at 3 sites. PRISM was compared to a Binder condition wherein participants received a notebook that contained paper content similar to that contained in PRISM. The sample included 300 older adults at risk for social isolation who lived independently in the community (Mage = 76.15 years). Primary outcome measures included indices of social isolation, social support, loneliness, and well-being. Secondary outcome measures included indices of computer proficiency and attitudes toward technology. Data were collected at baseline and at 6 and 12 months post-randomization. The PRISM group reported significantly less loneliness and increased perceived social support and well-being at 6 months. There was a trend indicating a decline in social isolation. Group differences were not maintained at 12 months, but those in the PRISM condition still showed improvements from baseline. There was also an increase in computer self-efficacy, proficiency, and comfort with computers for PRISM participants at 6 and 12 months. The findings suggest that access to technology applications such as PRISM may enhance social connectivity and reduce loneliness among older adults and has the potential to change attitudes toward technology and increase technology self-efficacy. © The Author 2017.

  19. Mechanical Coupling Error Suppression Technology for an Improved Decoupled Dual-Mass Micro-Gyroscope

    Directory of Open Access Journals (Sweden)

    Bo Yang

    2016-04-01

    Full Text Available This paper presents technology for the suppression of the mechanical coupling errors for an improved decoupled dual-mass micro-gyroscope (DDMG. The improved micro-gyroscope structure decreases the moment arm of the drive decoupled torque, which benefits the suppression of the non-ideal decoupled error. Quadrature correction electrodes are added to eliminate the residual quadrature error. The structure principle and the quadrature error suppression means of the DDMG are described in detail. ANSYS software is used to simulate the micro-gyroscope structure to verify the mechanical coupling error suppression effect. Compared with the former structure, simulation results demonstrate that the rotational displacements of the sense frame in the improved structure are substantially suppressed in the drive mode. The improved DDMG structure chip is fabricated by the deep dry silicon on glass (DDSOG process. The feedback control circuits with quadrature control loops are designed to suppress the residual mechanical coupling error. Finally, the system performance of the DDMG prototype is tested. Compared with the former DDMG, the quadrature error in the improved dual-mass micro-gyroscope is decreased 9.66-fold, and the offset error is decreased 6.36-fold. Compared with the open loop sense, the feedback control circuits with quadrature control loop decrease the bias drift by 20.59-fold and the scale factor non-linearity by 2.81-fold in the ±400°/s range.

    2011-10-01

    One of the problems in health care in developing countries is the bad accessibility of medicine in pharmacies for patients. Since this is mainly due to a lack of organization and information, it should be possible to improve the situation by introducing information and communication technology. However, for several reasons, standard solutions are not applicable here. In this paper, we describe a case study in Benin, a West African developing country. We identify the problem and the existing obstacles for applying standard ECommerce solutions. We develop an adapted system approach and describe a practical test which has shown that the approach has the potential of actually improving the pharmaceutical care delivery. Finally, we consider the security aspects of the system and propose an organizational solution for some specific security problems.

    There are 62 million Americans currently residing in rural areas who are more likely to have multiple chronic conditions and be economically disadvantaged, and in poor health, receive less recommended preventive services and attend fewer visits to health care providers. Recent advances in mobile healthcare (mHealth) offer a promising new approach to solving health disparities and improving chronic illness care. It is now possible and affordable to transmit health information, including values from glucometers, automated blood pressure monitors, and scales, through Bluetooth-enabled devices. Additionally, audio and video communications technologies can allow healthcare providers to conduct many parts of a physical exam remotely from varied settings. These technologies could remove geographical distance as a barrier to care and diminish the access to care issues faced by patients who live rurally. However, currently there is lack of studies that provide evidence of feasibility, acceptability, and effectiveness of mHealth initiatives on improved outcomes of care, a needed step to make the translation to implementation studies in healthcare systems. The purpose of this paper is to present the protocol for the first study of mI SMART (mobile Improvement of Self-Management Ability through Rural Technology), a new integrated mHealth intervention. Our objective is to provide evidence of feasibility and acceptability for the use of mI SMART in an underserved population and establish evidence for the refinement of mI SMART. The proposed study will take place at Milan Puskar Health Right, a free primary care clinic in the state of West Virginia. The clinic provides health care at no cost to uninsured, low income; adults aged 18-64 living in West Virginia. We will enroll 30 participants into this feasibility study with plans of implementing a longitudinal randomized, comparative effectiveness design in the future. Data collection will include tracking of barriers and

    Iron oxide-apatite (IOA) ore deposits occur globally and can host millions to billions of tons of Fe in addition to economic reserves of other metals such as rare earth elements, which are critical for the expected growth of technology and renewable energy resources. In this study, we pair the stable Fe and O isotope compositions of magnetite samples from several IOA deposits to constrain the source reservoir of these elements in IOAs. Since magnetite constitutes up to 90 modal% of many IOAs, identifying the source of Fe and O within the magnetite may elucidate high-temperature and/or lower-temperature processes responsible for their formation. Here, we focus on the world-class Los Colorados IOA in the Chilean iron belt (CIB), and present data for magnetite from other Fe oxide deposits in the CIB (El Laco, Mariela). We also report Fe and O isotopic values for other IOA deposits, including Mineville, New York (USA) and the type locale, Kiruna (Sweden). The ranges of Fe isotopic composition (δ56Fe, 56Fe/54Fe relative to IRMM-14) of magnetite from the Chilean deposits are: Los Colorados, δ56Fe (±2σ) = 0.08 ± 0.03‰ to 0.24 ± 0.08‰; El Laco, δ56Fe = 0.20 ± 0.03‰ to 0.53 ± 0.03‰; Mariela, δ56Fe = 0.13 ± 0.03‰. The O isotopic composition (δ18O, 18O/16O relative to VSMOW) of the same Chilean magnetite samples are: Los Colorados, δ18O (±2σ) = 1.92 ± 0.08‰ to 3.17 ± 0.03‰; El Laco, δ18O = 4.00 ± 0.10‰ to 4.34 ± 0.10‰; Mariela, δ18O = (1.48 ± 0.04‰). The δ18O and δ56Fe values for Kiruna magnetite yield an average of 1.76 ± 0.25‰ and 0.16 ± 0.07‰, respectively. The Fe and O isotope data from the Chilean IOAs fit unequivocally within the range of magnetite formed by high-temperature magmatic or magmatic-hydrothermal processes (i.e., δ56Fe 0.06-0.49‰ and δ18O = 1.0-4.5‰), consistent with a high-temperature origin for Chilean IOA deposits. Additionally, minimum formation temperatures calculated by using the measured Δ18O

    2004-05-01

    Developers of NBIC (Nano-Bio-Info-Cogno) technologies face a multitude of obstacles, not the least of which is navigating the public ethics of their applied research. Biotechnologies have received widespread media attention and spawned heated interest in their perceived social implications. Now, in view of the rapidly expanding purview of neuroscience and the growing array of technologic developments capable of affecting or monitoring cognition, the emerging field of neuroethics calls for a consideration of the social and ethical implications of neuroscientific discoveries and trends. To negotiate the complex ethical issues at stake in new and emerging kinds of technologies for improving human cognition, we need to overcome political, disciplinary, and religious sectarianism. We need analytical models that protect values of personhood at the heart of a functional democracy-values that allow, as much as possible, for individual decision-making, despite transformations in our understanding and ability to manipulate cognitive processes. Addressing cognitive enhancement from the legal and ethical notion of "cognitive liberty" provides a powerful tool for assessing and encouraging NBIC developments.

    Li, Jia; Macdonald, Joanne

    2016-09-15

    Lateral flow biosensors are a leading technology in point-of-care diagnostics due to their simplicity, rapidness and low cost. Their primacy in this arena continues through technological breakthroughs such as multiplexing: the detection of more than one biomarker in a single assay. Multiplexing capacity is critical for improving diagnostic efficiency, enhancing the diagnostic precision for specific diseases and reducing diagnostic cost. Here we review, for the first time, the various types and strategies employed for creating multiplexed lateral flow biosensors. These are classified into four main categories in terms of specific application or multiplexing level, namely linear, parameter, spatial and conceptual. We describe the practical applications and implications for each approach and compare their advantages and disadvantages. Importantly, multiplexing is still subject to limitations of the traditional lateral flow biosensor, such as sensitivity and specificity. However, by pushing the limitations of the traditional medium into the multiplex arena, several technological breakthroughs are emerging with novel solutions that further expand the utility of lateral flow biosensing for point-of-care applications.

  14. Hazardous waste management in Chilean main industry: An overview

    International Nuclear Information System (INIS)

    Navia, Rodrigo; Bezama, Alberto

    2008-01-01

    The new 'Hazardous Waste Management Regulation' was published in the Official Newspaper of the Chilean Republic on 12 June 2003, being in force 365 days after its publication (i.e., 12 June 2004). During the next 180 days after its publication (i.e., until 12 December 2004), each industrial facility was obligated to present a 'Hazardous Waste Management Plan' if the facility generates more than 12 ton/year hazardous wastes or more than 12 kg/year acute toxic wastes. Based on the Chilean industrial figures and this new regulation, hazardous waste management plans were carried out in three facilities of the most important sectors of Chilean industrial activity: a paper production plant, a Zn and Pb mine and a sawmill and wood remanufacturing facility. Hazardous wastes were identified, classified and quantified in all facilities. Used oil and oil-contaminated materials were determined to be the most important hazardous wastes generated. Minimization measures were implemented and re-use and recycling options were analyzed. The use of used oil as alternative fuel in high energy demanding facilities (i.e., cement facilities) and the re-refining of the used oil were found to be the most suitable options.

    The new "Hazardous Waste Management Regulation" was published in the Official Newspaper of the Chilean Republic on 12 June 2003, being in force 365 days after its publication (i.e., 12 June 2004). During the next 180 days after its publication (i.e., until 12 December 2004), each industrial facility was obligated to present a "Hazardous Waste Management Plan" if the facility generates more than 12 ton/year hazardous wastes or more than 12 kg/year acute toxic wastes. Based on the Chilean industrial figures and this new regulation, hazardous waste management plans were carried out in three facilities of the most important sectors of Chilean industrial activity: a paper production plant, a Zn and Pb mine and a sawmill and wood remanufacturing facility. Hazardous wastes were identified, classified and quantified in all facilities. Used oil and oil-contaminated materials were determined to be the most important hazardous wastes generated. Minimization measures were implemented and re-use and recycling options were analyzed. The use of used oil as alternative fuel in high energy demanding facilities (i.e., cement facilities) and the re-refining of the used oil were found to be the most suitable options. In the Zn and Pb mine facility, the most important measure was the beginning of the study for using spent oils as raw material for the production of the explosives used for metals recovery from the rock. In Chile, there are three facilities producing alternative fuels from used oil, while two plants are nowadays re-refining oil to recycle it as hydraulic fluid in industry. In this sense, a proper and sustainable management of the used oil appears to be promissory.

    In recent years the earthquake complex networks have been used as a useful tool to describe and characterize the behavior of seismicity. The earthquake complex network is built in space, dividing the three dimensional space in cubic cells. If the cubic cell contains a hypocenter, we call this cell like a node. The connections between nodes follows the time sequence of the occurrence of the seismic events. In this sense, we have a spatio-temporal configuration of a specific region using the seismicity in that zone. In this work, we are applying complex networks to characterize the subduction zone along the coast of Chile using two networks: a directed and an undirected network. The directed network takes in consideration the time-direction of the connections, that is very important for the connectivity of the network: we are considering the connectivity, ki of the i-th node, like the number of connections going out from the node i and we add the self-connections (if two seismic events occurred successive in time in the same cubic cell, we have a self-connection). The undirected network is the result of remove the direction of the connections and the self-connections from the directed network. These two networks were building using seismic data events recorded by CSN (Chilean Seismological Center) in Chile. This analysis includes the last largest earthquakes occurred in Iquique (April 2014) and in Illapel (September 2015). The result for the directed network shows a change in the value of the critical exponent along the Chilean coast. The result for the undirected network shows a small-world behavior without important changes in the topology of the network. Therefore, the complex network analysis shows a new form to characterize the Chilean subduction zone with a simple method that could be compared with another methods to obtain more details about the behavior of the seismicity in this region.

    The aim of the study was to characterize the anthropometric profile and somatotype of a sample of 50 players table tennis competitive with an average age 21.6 (± 3.1) years belonging to the Chilean team and institutions of higher education in the region of Valparaiso. The evaluation was conducted under the protocol marking the International Society for the Advancement of Kinanthropometry (ISAK) for the measurement procedure 25 restricted profile variables described by Drinkwater, Norton and Olds. Order to determine the body composition, fat, muscle, bone, skin and tissue residual was considered, using the equations proposed by Kerr. The body shape is characterized through somatotype method proposed by Carter. The sample was divided into 4 groups; Chilean Selection, Traditional Private Universities, State Universities and Private Universities Traditional Nontraditional. Regarding body composition; the Chilean team has the highest values of muscle tissue (45.6 ± 1.7%) and the lowest values of adipose tissue (25.2 ± 1.8%), also presenting lesser value in the Σ 6 skinfolds (mm) . The results showed no significant differences between groups in the aforementioned variables. In general somatotype compared by analyzing SANOVA no significant differences between groups (p = 0.409) was observed. The results show a biotype with such a characterization of endo-mesomorph with average values (4,1-4,9-1,8). This study provides updated data biotypological reference for this sport that can be used for decision-making. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

    Information technology in health care has a clear potential to improve the quality and efficiency of health care, especially in the area of medication processes. On the other hand, existing studies show possible adverse effects on patient safety when IT for medication-related processes is developed, introduced or used inappropriately. To summarize definitions and observations on IT usage in pharmacotherapy and to derive recommendations and future research priorities for decision makers and domain experts. This memorandum was developed in a consensus-based iterative process that included workshops and e-mail discussions among 21 experts coordinated by the Drug Information Systems Working Group of the German Society for Medical Informatics, Biometry and Epidemiology (GMDS). The recommendations address, among other things, a stepwise and comprehensive strategy for IT usage in medication processes, the integration of contextual information for alert generation, the involvement of patients, the semantic integration of information resources, usability and adaptability of IT solutions, and the need for their continuous evaluation. Information technology can help to improve medication safety. However, challenges remain regarding access to information, quality of information, and measurable benefits.

    Patients with multiple chronic conditions face many stressors (e.g. financial, safety, transportation stressors) that are rarely prioritized for discussion with the primary care provider (PCP). In this pilot randomized controlled trial we examined the effects of a novel technology-based intervention called Customized Care on stressor disclosure. The main outcomes were stressor disclosure, patient confidence and activation, as assessed by self-report and observational methods (transcribed and coded audio-recordings of the office visit). Sixty patients were enrolled. Compared with care as usual, intervention patients were 6 times more likely to disclose stressors to the PCP (OR=6.16, 95% CI [1.53, 24.81], p=0.011) and reported greater stressor disclosure confidence (exp[B]=1.06, 95% CI [1.01, 1.12], p=0.028). No differences were found in patient activation or the length of the office visit. Customized Care improved the likelihood of stressor disclosure without affecting the length of the PCP visit. Brief technology-based interventions, like Customized Care could be made available through patient portals, or on smart phones, to prime patient-PCP discussion about difficult subjects, thereby improving the patient experience and efficiency of the visit.

    Full Text Available Delivery of geospatial information over the Internet for the management of risks from invasive alien species is an increasingly important service. The evolution of information technology standards for geospatial data is a key factor to simplify network publishing and exchange of maps and data. The World Wide Web Consortium (W3C-geolocation specification is a recent addition that may prove useful for pest risk management. In this article we implement the W3C-geolocation specification and Open Geospatial Consortium (OGC mapping standards in a Web browser application for smartphones and tablet computers to improve field surveys for alien invasive species. We report our first season field experiences using this tool for online mapping of plant disease outbreaks and host plant occurrence. It is expected that the improved field data collection tools will result in increased data availability and thereby new opportunities for risk assessment, because data-needs and availability are crucial for species distribution modelling and model-based forecasts of pest establishment potential. Finally, we close with a comment on the future potential of geospatial information standards to enhance the translation from data to decisions regarding pest risks, which should enable earlier detection of emerging risks as well as more robust projections of pest risks in novel areas. The forthcoming standard for processing of geospatial information, the Web Processing Standard (WPS, should open new technological capabilities both for automatic initiation and updating of risk assessment models based on new incoming data, and subsequent early warning.

    To determine patient perceptions of using a demonstration application (app) of mobile technology to improve medication adherence and to identify desired features to assist in the management of medications. A qualitative study using key informant interviews was conducted in a community pharmacy chain for patients aged 50 and older, on statin therapy and owning a smart device. Three main themes emerged from 24 interviews at four pharmacy locations, which included benefits, barriers and desired features of the app. Benefits such as accessibility, privacy, pros of appearance and beneficiaries were more likely to lead to usage of the app. Barriers that might prevent usage of the app were related to concerns of appearance, the burden it might cause for others, cost, privacy, motivation and reliability. Specific features patients desired were categorized under appearance, customization, communication, functionality, input and the app platform. Patients provided opinions about using a mobile app to improve medication adherence and assist with managing medications. Patients envisioned the app within their lifestyle and expressed important considerations, identifying benefits to using this technology and voicing relevant concerns. App developers can use patient perceptions to guide development of a mobile app addressing patient medication-related needs. © 2015 Royal Pharmaceutical Society.

    Topical antipsoriatics are recommended first-line treatment of psoriasis, but rates of adherence are low. Patient support by use of electronic health (eHealth) services is suggested to improve medical adherence. To review randomised controlled trials (RCTs) testing eHealth interventions designed to improve adherence to topical antipsoriatics and to review applications for smartphones (apps) incorporating the word psoriasis. Literature review: Medline, Embase, Cochrane, PsycINFO and Web of Science were searched using search terms for eHealth, psoriasis and topical antipsoriatics. General analysis of apps: The operating systems (OS) for smartphones, iOS, Google Play, Microsoft Store, Symbian OS and Blackberry OS were searched for apps containing the word psoriasis. Literature review: Only one RCT was included, reporting on psoriasis patients' Internet reporting their status of psoriasis over a 12-month period. The rate of adherence was measured by Medication Event Monitoring System (MEMS ® ). An improvement in medical adherence and reduction of severity of psoriasis were reported. General analysis of apps: A total 184 apps contained the word psoriasis. There is a critical need for high-quality RCTs testing if the ubiquitous eHealth technologies, for example, some of the numerous apps, can improve psoriasis patients' rates of adherence to topical antipsoriatics.

    A growing body of research has employed mobile technologies and geographic information systems (GIS) for enhancing health care and health information systems, but there is yet a lack of studies of how these two types of systems are integrated together into the information infrastructure of an organization so as to provide a basis for data analysis and decision support. Integration of data and technical systems across the organization is necessary for efficient large-scale implementation. The aim of this paper is to identify how mobile technologies and GIS applications have been used, independently as well as in combination, for improving health care. The electronic databases PubMed, BioMed Central, Wiley Online Library, Scopus, Science Direct, and Web of Science were searched to retrieve English language articles published in international academic journals after 2005. Only articles addressing the use of mobile or GIS technologies and that met a prespecified keyword strategy were selected for review. A total of 271 articles were selected, among which 220 concerned mobile technologies and 51 GIS. Most articles concern developed countries (198/271, 73.1%), and in particular the United States (81/271, 29.9%), United Kingdom (31/271, 11.4%), and Canada (14/271, 5.2%). Applications of mobile technologies can be categorized by six themes: treatment and disease management, data collection and disease surveillance, health support systems, health promotion and disease prevention, communication between patients and health care providers or among providers, and medical education. GIS applications can be categorized by four themes: disease surveillance, health support systems, health promotion and disease prevention, and communication to or between health care providers. Mobile applications typically focus on using text messaging (short message service, SMS) for communication between patients and health care providers, most prominently reminders and advice to patients.

  6. THE RESPONSE OF MONTEREY BAY TO THE 2010 CHILEAN EARTHQUAKE

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available The primary frequencies contained in the arrival sequence produced by the tsunami from the Chilean earthquake of 2010 in Monterey Bay were extracted to determine the seiche modes that were produced. Singular Spectrum Analysis (SSA and Ensemble Empirical Mode Decomposition (EEMD were employed to extract the primary frequencies of interest. The wave train from the Chilean tsunami lasted for at least four days due to multipath arrivals that may not have included reflections from outside the bay but most likely did include secondary undulations, and energy trapping in the form of edge waves, inside the bay. The SSA decomposition resolved oscillations with periods of 52-57, 34-35, 26-27, and 21-22 minutes, all frequencies that have been predicted and/or observed in previous studies. The EEMD decomposition detected oscillations with periods of 50-55 and 21-22 minutes. Periods in the range of 50-57 minutes varied due to measurement uncertainties but almost certainly correspond to the first longitudinal mode of oscillation for Monterey Bay, periods of 34-35 minutes correspond to the first transverse mode of oscillation that assumes a nodal line across the entrance of the bay, a period of 26- 27 minutes, although previously observed, may not represent a fundamental oscillation, and a period of 21-22 minutes has been predicted and observed previously. A period of ~37 minutes, close to the period of 34-35 minutes, was generated by the Great Alaskan Earthquake of 1964 in Monterey Bay and most likely represents the same mode of oscillation. The tsunamis associated with the Great Alaskan Earthquake and the Chilean Earthquake both entered Monterey Bay but initially arrived outside the bay from opposite directions. Unlike the Great Alaskan Earthquake, however, which excited only one resonant mode inside the bay, the Chilean Earthquake excited several modes suggesting that the asymmetric shape of the entrance to Monterey Bay was an important factor and that the

  9. New marine commons along the Chilean coast – the management areas (MAs of Peñuelas and Chigualoco

    Directory of Open Access Journals (Sweden)

    Gloria L. Gallardo Fernández

    2011-09-01

    Full Text Available To halt degradation of benthic resources in Chile, management areas (MAs were set up under the Territorial Use Rights in Fisheries (TURFs framework in the late 1990s. Integrated into the global market, MAs have since expanded along the Chilean coast, involving thousands of small-scale artisanal fishers. This paper analyses how economic criteria relates to social and ecological performance of Chilean MAs, by applying TURFs, commons and co-management theory to two cases: MAs Peñuelas and Chigualoco. To collect and analyse data Participatory Rural Appraisal tools, interviews and official statistics and reports were used. Our results show that MAs’ economic benefits are connected to fluctuations on the global market. Adapting to changing world market prices then becomes paramount. TURFs’ main goal is ecological conservation, but achieving this seems to depend on meeting fishers’ livelihoods; failure to do so likely results in failure to meet conservation objectives. A serious weakness of the Chilean TURFs system is that it does not pay enough attention to fishers’ livelihoods or to the global market context. Furthermore, there is a strong relationship between good economic benefits and social sustainability. But irrespective of economic performance, fisher organizations have been empowered and gained increased resource control with the TURFs system. At policy level, a differentiated and more flexible system could be more suitable for existing heterogeneous MAs and their particular economic, social and ecological challenges. For improved economic sustainability and resource conservation, a system with multiple-species managing MAs could be promoted as well. Finally, to enhance theory of commons, co-management and TURFs, we argue for greater acknowledgement of TURFs’ social benefits in addition to economic assessments. More attention should also be paid to global market conditions of which MAs are dependent and in which they are embedded

    Full Text Available The Province of East Nusa Tenggara (NTT had been one of the major beef cattle suppliers under traditional management system in Indonesia. The beef cattle farming that based on grazing native pasture and the introduction of shrub legumes (Leucaena leucocephala may contribute to around 15 – 50% of the farmers’ household income. In the last few years, supply of beef cattle tended to decline due to the decrease in cattle population in NTT. Some basic improvements in management and feeding toward increasing beef cattle productivities had been carried out in Nusa Tenggara, such as a baseline survey on Cattle Health and Productivity Survey (CHAPS conducted in 1990 – 1992. The objective of the program was to identify the existing beef cattle productivity and health condition throughout Nusa Tenggara. A collaborative research with the Ministry of Research and Technology (Integrated Prime Research had also been carried out and the result showed that early weaning in Bali calves that can be practised as early as 3 – 6 months to prevent calves losses during the dry season. A program of the Assessment on Beef Cattle Base Farming Activities had also been conducted to improve fattening and breeding practices through the improvement in beef cattle management and feeding systems. At the latest development, fattening scheme has been introduced under a partnership approach involving private sectors and cooperatives. This needs to be facilitated by the government to accelerate the program such as access to capital and intensive extension services to build farmers awareness toward profit oriented beef cattle farming. Optimalization of the available potential resources and technology in NTT, will be an opportunity to enhance beef cattle production and gains back the reputation as one of the major producing beef cattle in the past. This will also support the national livestock program nowadays, called Beef Cattle Self Sufficiency Program 2014.

    The salinity problem is one of the severe constraints for agriculture in Pakistan. In a socio-economic and salinity and drainage survey over an area of about 25000 acres of salt-affected land recently, crop production is found to be very low. Livestock is underfed and malnourished. Pakistan has spent and allocated over one billion US dollars on Salinity Control and Reclamation Projects (SCARP), of course, with dubious results. Over the years, a Saline Agriculture Technology has been developed as a cheap alternative at NIAB for comfortably living with salinity and to profitably utilize saline land rather than its reclamation. The soil improvement is a fringe benefit in this approach. The Saline Agriculture Technology has been tested at laboratory level, at field stations and at farms of some progressive farmers. Now we are sharing this technology with farming communities through a 'Saline Agriculture Farmer Participatory Development Project in Pakistan', with assistance from the National Rural Support Programme. The new project has been launched simultaneously in all four provinces of Pakistan on 25000 acres of salt-affected land. Under this project seeds of salt tolerant crop varieties wheat, cotton, rice, castor, brassica and barley and saplings of trees/shrubs, e.g. Acacia ampliceps, A. nilotica, Casuarina glauca, ber, jaman, etc selected for development work in various institutions of Pakistan are being provided to farmers. Know-how on new irrigation techniques like bed-and-corrugation and bed-and-furrow, agronomic practices like laser land leveling, planting on beds and in auger holes and soil/water amendment practices (use of gypsum and mineral acids) are being shared with farmers. These interventions are quite efficient, save water up to 40% and enable farmers to utilize bad quality water. In general, farmers are being familiarized with prevalent animal diseases, nutritional problems and prophylactic techniques. They are being helped in developing Saline

    Extreme ultraviolet lithography (EUVL) technology is getting closer to high volume manufacturing phase every year. In order to enhance the yield of EUV lithography processing, further improvement of defectivity and CD uniformity is required at the moment. In our previous report in 2017, we have exhibited the defectivity reduction by applying our new rinse and dispense system to a 24nm contact hole (CH) pattern. On the basis of the knowledge received through that evaluation, further study for improvement of the defectivity has been investigated in this paper. As a result of further optimization of the rinse process, 83 % further reduction of residue defect from the result reported previously is achieved. Also, CD uniformity control is a very crucial factor towards EUVL manufacturing phase. We have exposed 15 wafer batches continuously for both line/space and contact hole patterns in order to confirm the current status of wafer to wafer (WTW) as well as field to field (FTF), die to die (DTD), and local uniformity. Now further work for improving CD stability is ongoing based on the results from this first trial.

    Shailam, Randheer; Botwin, Ariel; Stout, Markus; Gee, Michael S

    The purpose of our study was to create a real-time electronic dashboard in the pediatric radiology reading room providing a visual display of updated information regarding scheduled and in-progress radiology examinations that could help radiologists to improve clinical workflow and efficiency. To accomplish this, a script was set up to automatically send real-time HL7 messages from the radiology information system (Epic Systems, Verona, WI) to an Iguana Interface engine, with relevant data regarding examinations stored in an SQL Server database for visual display on the dashboard. Implementation of an electronic dashboard in the reading room of a pediatric radiology academic practice has led to several improvements in clinical workflow, including decreasing the time interval for radiologist protocol entry for computed tomography or magnetic resonance imaging examinations as well as fewer telephone calls related to unprotocoled examinations. Other advantages include enhanced ability of radiologists to anticipate and attend to examinations requiring radiologist monitoring or scanning, as well as to work with technologists and operations managers to optimize scheduling in radiology resources. We foresee increased utilization of electronic dashboard technology in the future as a method to improve radiology workflow and quality of patient care. Copyright © 2017 Elsevier Inc.

    Context • Depending on the cause of the infertility, nonsurgical or surgical treatments may be used to treat men and women with infertility. Despite improved outcomes due to medical advances, assisted reproductive technology (ART) for couples with infertility is sometimes unsuccessful. Success may be affected by the patient's social, psychological, and physical status. Objective • The study examined the effects of yoga-including asanas (yoga poses), pranayama (proper breathing), shavasana, and meditation-on male and female fertility and ART outcomes. Design • The research team performed a literature review, electronically searching for articles published between January 1978 and January 2016 in the PubMed, Scopus, ScienceDirect, and Google Scholar databases. Setting • The study took place at the Reproductive Biotechnology Research Center at the Avicenna Research Institute at the Academic Center for Education, Culture, and Research (Tehran, Iran). Participants • Participants were couples with infertility taking part in 87 reviewed studies. Intervention • Yoga was the intervention. Outcome Measures • The outcome measures comprised fertility factors in males and females, fertility rate, and ART success rate. Results • The reviewed studies showed that yoga can provide stress management for patients with infertility, with beneficial effects on fertility, helping couples give birth. They found that yoga also could reduce pain; decrease depression, anxiety, and stress; reduce the rate of assisted vaginal delivery; and improve fetal outcomes. Conclusions • Yoga can help couples overcome infertility and increase the ART success rate by improving the physiological and psychological states of both men and women.

In the wake of the green revolution, yield gains have been in steady decline, while post-harvest crop losses have increased as a result of insufficiently resourced and uncoordinated efforts to control spoilage throughout global transport and storage networks. This paper focuses on the role that biosecurity is set to play in future food security by preventing both pre- and post-harvest losses, thereby protecting crop yield. We model biosecurity as a food security technology that may complement conventional yield improvement policies if the gains in global farm profits are sufficient to offset the costs of implementation and maintenance. Using phytosanitary measures that slow global spread of the Ug99 strain of wheat stem rust as an example of pre-border biosecurity risk mitigation and combining it with post-border surveillance and invasive alien species control efforts, we estimate global farm profitability may be improved by over US$4.5 billion per annum.

    Full Text Available Health Data collection is one of the major components of public health systems. Decision makers, policy makers, and medical service providers need accurate and timely data in order to improve the quality of health services. The rapid growth and use of mobile technologies has exerted pressure on the demand for mobile-based data collection solutions to bridge the information gaps in the health sector. We propose a prototype using open source data collection frameworks to test its feasibility in improving the vaccination data collection in Kenya. KenVACS, the proposed prototype, offers ways of collecting vaccination data through mobile phones and visualizes the collected data in a web application; the system also sends reminder short messages service (SMS to remind parents on the date of the next vaccination. Early evaluation demonstrates the benefits of such a system in supporting and improving vaccination of children. Finally, we conducted a qualitative study to assess challenges in remote health data collection and evaluated usability and functionality of KenVACS.

    According to a 2004 report by the Joint United Nations Programme on HIV/AIDS, Chile has an incipient HIV/AIDS epidemic. Regardless of the classification, every year the cumulative incidence of HIV/AIDS increases. Young Chileans have been the most affected group; still, their knowledge, attitudes, and concerns about HIV/AIDS are not known. This study describes Chilean university students' HIV/AIDS-related knowledge, their worry about getting the virus, and the correlation between both variables. A convenience sample of 45 university students responded to an anonymous self-administered questionnaire after orally consenting to participate in this study. Overall, students had good levels of HIV/AIDS-related knowledge, with 77% responding correctly to at least 85% of the questions. Despite this knowledge, almost 56% of students stated that they were not worried about getting HIV/AIDS. The situation was corroborated by a nonsignificant statistical correlation between both variables (p > .05). These results are congruent with literature from other countries and strengthen the need for further research to clarify why university students, the majority of whom are well-educated and engage in behaviors that place them at risk for contracting the virus, do not worry about HIV.

    In patients with an artificial airway, inspired gases can be humidified and heated using a passive (heat and moisture exchange filter - HMEF), or an active system (heated humidifier). To assess how humidification is carried out and what is the usual clinical practice in this field in Chilean intensive care units (ICUs). A specific survey to evaluate humidification system features as well as caregivers' preferences regarding humidification systems, was carried out on the same day in all Chilean ICUs. Fifty-five ICUs were contacted and 44 of them completed the survey. From a total of 367 patients, 254 (69%) required humidification because they were breathing through an artificial airway. A heated humidifier was employed only in 12 patients (5%). Forty-three ICUs (98%) used HMEF as their routine humidification system. In 52% of surveyed ICUs, heated humidifiers were not available. In Chile the main method to humidify and heat inspired gases in patients with an artificial airway is the HMEF. Although there are clear indications for the use of heated humidifiers, they are seldom employed.

  2. Chilean management education: rhetoric of pragmatism, consumerism, individualism and elitism

    Marcela Mandiola Cotroneo

    Full Text Available The aim of this paper is to understand the character and the role of higher education in business in relation to the wider institutional and structural contexts within which they function. Being loyal to that widespread background, business schools in Chile have become efficient providers of appropriate goods and services for their respective clients and consumers, behaving more like corporations and businesses rather than educational institutions. From this perspective, business education's alignment with the wider political and socio-economic shifts associated with the developments of market economies and economic globalization is a necessary reflection. In this paper we will provide an account of our problematization of management education practices in Chile. This practice was pictured as one of the main characters at the forefront of the Chilean neo-liberal revolution during the final years of the last century. In particular, we will unravel more closely the chain of signifiers articulating the meaning of Chilean higher business education. This articulation is recuperated mainly around how those involved in the management education practice talk about (ourthemselves. As well as specialised press writings, some academic accounts and fragments from our own 'ethnographic' involvement are used for this purpose. Particular attention is paid to the social, political and fantasmatic logics (GLYNOS; HOWARTH, 2007 as key elements of our own explanation of this practice, which in turn informs our critical standpoint.

    Phenylketonuria (PKU, OMIM 261600) is an autosomal recessive disease, caused by mutations in the Phenylalanine Hydroxylase (PAH) gene situated in chromosome 12q22-q24.2. This gene has 13 exons. To date, 991 mutations have been described. The genotype is one of the main factors that determine the phenotype of this disease. Characterize PKU genotype and phenotype seen in Chilean PKU patients. We studied the PAH gene by restriction fragment length polymorphism (RFLP) and/or sequencing techniques to identify pathogenic mutations in 71 PKU subjects. We classified the phenotype according to Guldberg predicted value. We identified 26 different mutations in 134 of the 142 alleles studied (94.4%), 88.7% of the subjects had biallelic pathogenic mutations while 11.3% had only one pathogenic mutation identified. Compound heterozygous represented 85.9% of the cases. Exon 7 included the majority of mutations (26.9%) and 50% of mutations were missense. The most frequent mutations were c.1066-11G > A, c.442-?_509+?del and p.Val388Met. The majority of subjects (52.3%) had the classic phenotype. The most frequent mutations in our Chilean PKU population were p.Val388Met, c.442?_509+?del and c.1066-11G > A. It is possible to predict phenotype by detecting the genotype, and use this information to determine disease prognosis and adjust patient's medical and nutritional management accordingly.

  4. Twilight vertical migrations of zooplankton in a Chilean fjord

    2014-12-01

    Time series of acoustic backscatter and vertical velocity profiles were obtained at three sites along a Chilean fjord with the purpose of determining dominant structures of vertical migrations of the sound scattering layer. Ancillary data obtained with stratified net samples indicated that the sound scattering layer may have been dominated by euphausiids and decapods. Therefore, distributions of acoustic backscatter anomalies and vertical velocities were attributed to vertical migrations of predominantly these organisms. Migration patterns were dominated by twilight excursions in which organisms swam toward the water surface at sunset, spent 100 m). This migration strategy can also be termed 'semidiel migration' as two double excursions were linked to light levels. The reasons for this twilight migration remain uncertain. But it is possible that the up and down motion around sunset was related to predation avoidance, hunger-satiation state, ontogeny, seaward transport evasion, or reaction to the environmental shock from the pycnocline, or a combination of all or some of them. In contrast, the sunrise double excursion was probably linked to feeding requirements by organisms that need to spend the day at great depth with no food available. This study demonstrated the existence of semidiel patterns throughout the fjord and through prolonged periods. In addition, identification of this pattern by acoustic backscatter was complemented by direct vertical velocity measurements. It is proposed that twilight vertical migration is a common strategy in Chilean fjords.

    Full Text Available Nicolás H Beltrán, Manuel A Duarte-Mermoud, Ricardo E MuñozDepartment of Electrical Engineering, University of Chile, Santiago, ChileAbstract: This paper discusses the classification of Chilean wines by geographical origin based only on aroma information. The varieties of Cabernet Sauvignon, Merlot, and Carménère analyzed here are produced in four different valleys in the central part of Chile (Colchagua, Maipo, Maule, and Rapel. Aroma information was obtained with a zNoseTM (fast gas chromatograph and the data was analyzed by applying wavelet transform for feature extraction followed by an analysis with support vector machines for classification. Two evaluations of the classification technique were performed; the average percentage of correct classification performed on the validation set was obtained by means of cross-validation against the percentage of correct classification obtained on the test set. This developed technique obtained results on classification rates over 94% in both cases. The geographical origin of a Chilean wine can be resolved rapidly with fast gas chromatography and data processing.Keywords: geographical origin, origin denomination, wine classification, pattern recognition, support vector machines, wavelet analysis, feature extraction

    This study is part of a screening program aimed at searching for bioactive metabolites from Chilean basidiomycetes. Submerged cultivation of fungal mycelia in liquid media was evaluated for antimicrobial activity. A total of 148 strains were obtained in vitro. The extracts produced from submerged cultures were evaluated against bacteria and fungi. In the primary antimicrobial assay, approximately 60% of the extracts presented positive biological activity. The highest frequencies of active strains were from the orders Agaricales (31.0%), Polyporales (20.6%), Sterales (18.3%), Boletales (11.4%), and Cortinariales (9.1%). Antifungal activity was more pronounced than antibacterial activity. Twelve extracts that exhibited strong antimicrobial activity showed minimum inhibitory concentration (MIC) values of 50 µL/mL against Bacillus brevis and 25∼50 µL/mL against Penicillium notatum and Paecilomyces variotii. The biological activity of some strains did not vary considerably, regardless of the substrate or collection site whereas, for others, it showed marked variations. Differences in antimicrobial activities observed in the different fungal genera suggested that the ability to produce bioactive compounds is not homogenously distributed among basidiomycetes. The information obtained from this study reveals that Chilean basidiomycetes are able to generate small and/or large variations in the normal pathway of compounds production. Thus, it is necessary to evaluate this biological and chemical wealth, which could be an unsuspected reservoir of new and potentially useful molecules. © Georg Thieme Verlag KG Stuttgart · New York.

    This paper reviews the development of new material and surface technology in tribology and its contribution to energy efficiency. Two examples of the economic benefits, resulted from the optimum tribology in the transportation sector and the manufacturing industry are discussed. The new materials are proposed to modify the surface property by laminating the bulk material with thin layer/coating. Under a suitable condition, the thin layer on a surface can provide a combination of good wear, a low friction and corrosion resistance for the mechanical components. The innovation in layer technology results molybdenum disulfide (MoS2), diamond like carbon (DLC), cubic boron nitride (CBN) and diamond which perform satisfactory outcome. The application of the metallic coatings to carbon fibre reinforced polymer matrix composites (CFRP) has the capacity to provide considerable weight and power savings for many engineering components. The green material for lubricant and additives such as the use of sunflower oil which possesses good oxidation resistance and the use of mallee leaves as bio-degradable solvent are used to answer the demand of the environmentally friendly material with good performance. The tribology research implementation for energy efficiency also touches the simple things around us such as: erasing the laser-print in a paper with different abrasion techniques. For the technology in the engineering surface, the consideration for generating the suitable surface of the components in running-in period has been discussed in order to prolong the components life and reduce the machine downtime. The conclusion, tribology can result in reducing manufacturing time, reducing the maintenance requirements, prolonging the service interval, improving durability, reliability and mechanical components life, and reducing harmful exhaust emission and waste. All of these advantages will increase the energy efficiency and the economic benefits.

    Flight deck-based vision systems, such as Synthetic and Enhanced Vision System (SEVS) technologies, have the potential to provide additional margins of safety for aircrew performance and enable the implementation of operational improvements for low visibility surface, arrival, and departure operations in the terminal environment with equivalent efficiency to visual operations. To achieve this potential, research is required for effective technology development and implementation based upon human factors design and regulatory guidance. This research supports the introduction and use of Synthetic Vision Systems and Enhanced Flight Vision Systems (SVS/EFVS) as advanced cockpit vision technologies in Next Generation Air Transportation System (NextGen) operations. Twelve air transport-rated crews participated in a motion-base simulation experiment to evaluate the use of SVS/EFVS in NextGen low visibility approach and landing operations. Three monochromatic, collimated head-up display (HUD) concepts (conventional HUD, SVS HUD, and EFVS HUD) and two color head-down primary flight display (PFD) concepts (conventional PFD, SVS PFD) were evaluated in a simulated NextGen Chicago O'Hare terminal environment. Additionally, the instrument approach type (no offset, 3 degree offset, 15 degree offset) was experimentally varied to test the efficacy of the HUD concepts for offset approach operations. The data showed that touchdown landing performance were excellent regardless of SEVS concept or type of offset instrument approach being flown. Subjective assessments of mental workload and situation awareness indicated that making offset approaches in low visibility conditions with an EFVS HUD or SVS HUD may be feasible.

    Over 50 years of nuclear fuels and materials irradiation testing has led to many countries developing significant improvements in instrumentation to monitor physical parameters and to control the test conditions in Materials Test Reactors (MTRs) or research reactors. Recent effort to deploy new fuels and materials in existing and advanced reactors has increased the demand for well-instrumented irradiation tests. Specifically, demand has increased for tests with sensors capable of providing real-time measurement of key parameters, such as temperature, geometry changes, thermal conductivity, fission gas release, cracking, coating buildup, thermal and fast flux, etc. This review paper documents the current state of instrumentation technologies in MTRs in the world and summarizes on-going research efforts to deploy new sensors. There is increased interest to irradiate new materials and reactor fuels for advanced PWRs and the Gen-IV reactor systems, such as SFRs (Sodium-cooled Fast Reactors), VHTRs (Very-High-Temperature Reactors), SCWRs (Supercritical-Water-cooled Reactors) and GFRs (Gas-cooled Fast Reactor). This review documents the current state of instrumentation technologies in MTRs in the world, identifies challenges faced by previous testing methods and how these challenges were overcome. A wide range of sensors are available to measure key parameters of interest during fuels and materials irradiations in MTRs. Such sensors must be reliable, small size, highly accurate, and able to withstand harsh conditions. On-going development efforts are focusing on providing MTR users a wider range of parameter measurements with increased accuracy. In addition, development efforts are focusing on reducing the impact of sensor on measurements by reducing sensor size. This report includes not only status of instrumentation using research reactors in the world to irradiate nuclear fuels and materials but also future directions relating to instrumentation technologies for

    This paper analyses recent, current and potential future relations between policy processes and substantive outcomes in UK low carbon innovation policy, focussing on policies relating to renewable electricity generation technologies. It examines the development of policy processes relating to the adoption and implementation of the Renewables Obligation and how these may affect the current and likely future success of the Obligation in promoting low carbon innovation. It examines the new policy and institutional processes put in place in the 2003 Energy White Paper and argues that these are unlikely to provide the strategic long-term framework needed to realise the ambitious goals for UK energy policy set out in the White Paper. Finally, it outlines some suggestions for further development of policy processes to facilitate improved delivery of these goals, based on guiding principles for sustainable innovation policy processes, developed by the authors and their colleagues

    A study was undertaken to examine the use of irradiation technology in improving the water quality. A Cobalt- 60 gamma radiation source was used in studying the removal of trihalo methane (THM) compounds from drinking water, which forms as a result of using chlorine for water disinfection. The study also includes the use of irradiation processing for water disinfection as a substitute of water chlorination. The results show that a dose of 1000 Gy is efficient in removing 100 μg/l of THM compounds from drinking water. The same dose is also found efficient for disinfecting and controlling the microbiological content of contaminated surface water. The highly contaminated raw municipal wastewater found to require a radiation dose in the range of 1000 to 5000 Gy. (authors)

    Historically, Brazil has promoted the development and sales of light duty vehicles running on ethanol (firstly, ethanol-dedicated cars, and recently flexfuel cars). In the 1990s, the country also favored the sales of compact cars to middle and low-income classes. However, in the last years, the profile of vehicles sold in Brazil has converged towards larger and less-efficient vehicles. In 2008, Brazil launched the vehicle labeling program. Based on the outcomes of the historical programs oriented towards the development of automotive innovations, and on a survey conducted with the country's main auto makers, this article evaluates whether the vehicle labeling program will both improve the energy efficiency of light vehicles, and introduce new technologies. Our results indicate that, despite its virtuous intentions, the program will not control the tendency of rising fuel consumption of passenger cars sold in Brazil. Therefore, other policies are needed to boost innovations in Brazil's automotive industry. (author)

    2012-07-31

    Steel foundries melt recycled scrap in electric furnaces and typically consume 35-100% excess energy from the theoretical energy requirement required to pour metal castings. This excess melting energy is multiplied by yield losses during casting and finishing operations resulting in the embodied energy in a cast product typically being three to six times the theoretical energy requirement. The purpose of this research project was to study steel foundry melting operations to understand energy use and requirements for casting operations, define variations in energy consumption, determine technologies and practices that are successful in reducing melting energy and develop new melting techniques and tools to improve the energy efficiency of melting in steel foundry operations.

    2009-01-28

    Innovation Partners proposed and successfully demonstrated in this SBIR Phase I grant a software/hardware co-design approach to reduce both the difficulty and time to implement Field Programmable Gate Array (FPGA) solutions to data acquisition and specialized computational applications. FPGAs can require excessive time for programming and require specialized knowledge that will be greatly reduced by the company's solution. Not only are FPGAs ideal for DAQ and embedded solutions, they can also be the best solution to specialized signal processing to replace Digital Signal Processors (DSPs). By allowing FPGA programming to be done in C with the equivalent of a simple compilation, algorithm changes and improvements can be implemented decreasing the life-cycle costs and allow subsitution of new FPGA designs staying above the technological details.

  17. Poverty Alleviation and Environmental Sustainability through Improved Regimes of Technology Transfer

    Klaus Bosselmann

    2006-06-01

    Full Text Available To achieve the Millennium Development Goals, international technology transfer can play a major role for poverty alleviation and environmental sustainability. At present, there are economic, social and legal (rather than technical barriers preventing the transfer of environmentally sound technology (EST from a wider use in international regimes. Removing these barriers requires greater political and regulatory efforts both domestically and internationally. To enable EST transfer, developed States need to improve domestic market conditions such as removal of negative subsidies and barriers to foreign investment, targeted fiscal incentives and law reforms favouring sustainable production and use of energy. There is no realistic perspective for international EST transfer as long as it is disadvantaged domestically. A coherent EST transfer regime is only possible through greater governmental intervention at the national and international level, including environmental regulations, national systems of innovation, and creating an enabling environment for EST. Such intervention should include effective public-private partnerships, both within and between States. Partnerships, if guided by law, could ensure EST innovation more efficiently than purely State-driven or market-driven EST transfers. In search for a model, the EST transfer regime under the Vienna Ozone Layer Convention and the Montreal Protocol deserves recognition. For example, the clean development mechanism under the Kyoto Protocol allows for considerable scope for EST transfer. The potential of EST transfer for climate change and for meeting the Millennium Development Goals has yet to be realized.

    2012-09-01

    Many accidents occur world-wide in the use of construction plant and equipment, and safety training is considered by many to be one of the best approaches to their prevention. However, current safety training methods/tools are unable to provide trainees with the hands-on practice needed. Game technology-based safety training platforms have the potential to overcome this problem in a virtual environment. One such platform is described in this paper - its characteristics are analysed and its possible contribution to safety training identified. This is developed and tested by means of a case study involving three major pieces of construction plant, which successfully demonstrates that the platform can improve the process and performance of the safety training involved in their operation. This research not only presents a new and useful solution to the safety training of construction operations, but illustrates the potential use of advanced technologies in solving construction industry problems in general.

  19. Criteria and model for assessing and improving information technology maturity within maintenance

    International Nuclear Information System (INIS)

    Kans, M; Ehsanifard, K; Moniri, A

    2012-01-01

    Maintenance optimization and decision-making processes have been both influenced considerably by Information Technology (IT) developments mainly by increasing data availability. The decision-making process in its turn has affected systems trustworthiness positively. Therefore, theoretically speaking it could be said that Maintenance Management Information technology (MMIT) has the potential to provide applicable solutions for many of the maintenance management problems. Nevertheless, this potential has been hardly experienced in practice because of the mismatch between the level of IT maturity in the organizations and their selected MMIT solutions. To fill this gap this paper suggests a number of criteria which are crucial in decision making for selecting a MMIT application. The criteria are formed based on previous findings utilising an extensive literature review. A model is further developed for this purpose which is also tested on a case company active in power generation in Sweden. The model proved to be helpful when taking further improvement steps for reaching high utilization of IT in maintenance.

    2009-01-01

    This research proposes a conceptual model for Knowledge Services Structure applicable to Science and Technology Parks (STP) and targeted to micro, small and medium enterprises, in order to improve the business - university - research centers relationship. The idea emerged from exploratory studies on STP and the observation of a knowledge gap on this subject: academic studies that have proposed support services structures to link companies - university - research centers in STP were not available. The study methodology is composed by: exploratory studies complemented by action research. Five aspects of analysis (knowledge services, business development, ordinary/ S and T infrastructure services, expansion of area, and image / visibility) were chosen; a questionnaire based on the these aspects were elaborated and applied by e-mail (e-survey), using as data-base the IASP associated members for the selection of potential respondents. The questionnaire was answered by STP managers from different countries (Spain, Italy, Portugal, Germany, United Kingdom, China, Brazil, Turkey and Uruguay) and, for a deeper and better answers understanding, presential interviews were conducted in certain European STP. After presentation, analysis and discussion of the results, a conceptual model of knowledge service structure for STP has been made, using as basis the Technology Park of Sao Paulo structure. During the formulation of the conceptual model stage, a brief discussion on the importance of knowing and meet the customer needs meant on the inclusion of a customer-interface in the final model.

  1. KEY TECHNOLOGICAL SOLUTIONS FROM THE SESAR PROGRAMME TO IMPROVE AIR TRAFFIC SAFETY

    Directory of Open Access Journals (Sweden)

    Jan LASKOWSKI

    2017-03-01

    Full Text Available The dynamic development of the air transport market has led to a significant increase in air traffic in a highly fragmented and relatively small European airspace. This situation could, in the near future, render the currently functioning European air traffic management (ATM system obsolete and incapable of providing the high safety standards demanded by the ICAO and Eurocontrol. Recognizing the urgency in finding a solution to this problem, the EU gas launched the Single European Sky (SES initiative, along with its technological pillar, the Single European Sky ATM Research (SESAR programme, which seeks to enhance air traffic safety, support the sustainable development of the air transport system and improve the overall performance of ATM and air navigation services, so that they meet the requirements of all airspace users. This paper presents a selection of the SESAR programme’s key technological solutions, such as approaches based on area navigation (RNAV/Global Navigation Satellite Systems (GNSS, and the “remote tower” concept, which have been developed to maximize the safety and efficiency of the new European ATM system.

    Full Text Available In this paper, rotating bending fatigue tests of 2024-T4 Al alloy with different oxide coatings were carried out. Compared to the uncoated and previously reported oxide coatings of aluminum alloys, the fatigue strength is able to be enhanced by using a novel oxide coating with sealing pore technology. These results indicate that the better the coating surface quality is, the more excellent the fatigue performance under rotating bending fatigue loading is. The improvement on the fatigue performance is mainly because the fatigue crack initiation and the early stage of fatigue crack growth at the coating layer can be delayed after PEO coating with pore sealing. Therefore, it is a so-called synergistic coating technology for various uses, including welding thermal cracks and filling micro-pores. The effects of different oxide coatings on surface hardness, compressive residual stress, morphology and fatigue fracture morphology are discussed. A critical compressive residual stress of about 95–100 MPa is proposed.

    Digital engagement has become pervasive in the delivery of cancer care. Internet- and cellular phone-based tools and systems are allowing large groups of people to engage with each other and share information. Health systems and individual health professionals are adapting to this revolution in consumer and patient behavior by developing ways to incorporate the benefits of technology for the purpose of improving the quality of medical care. One example is the use of social media platforms by oncologists to foster interaction with each other and to participate with the lay public in dialogue about science, medicine, and cancer care. In addition, consumer devices and sensors (wearables) have provided a new, growing dimension of digital engagement and another layer of patient-generated health data to foster better care and research. Finally, electronic health records have become the new standard for oncology care delivery, bringing new opportunities to measure quality in real time and follow practice patterns, as well as new challenges as providers and patients seek ways to integrate this technology along with other forms of digital engagement to produce more satisfaction in the process of care along with measurably better outcomes.

    The Electric Power Research Institute (EPRI) has undertaken an aggressive program, called ORAM (Outage Risk Assessment and Management), to provide utilities with tools and technology to assist in managing risk during the planning and conduct of outages. The ORAM program consists of the following 6 steps: i) Perform utility surveys and visits on shutdown risk management needs, ii) Perform probabilistic shutdown safety assessments (PSSAs) to identify generic insights that can be incorporated into risk management guidelines and identify selected areas for the development of contingency actions, iii) Develop risk management guidelines (RMG's) that provide a systematic approach to the planning and conduct of outages from a safety perspective. Incorporate insights from the shutdown safety assessments and other operating experience into the RMG's. iv) Develop selected contingency actions including a thermalhydraulic tool kit to address higher risk time periods and activities identified in the shutdown safety assessments, v) Develop computer software that integrates all of the above capability into an easy to use tool for effective shutdown operation management for utilities, vi) Provide assistance in the transfer of this technology and the application of these tools. This paper briefly describes the technical approach and tools developed under EPRI's ORAM program and its applications for improving outage safety and economics. (author)

    Multimedia technologies offer powerful tools to increase capacity of health workers to deliver standardized, effective, and engaging antiretroviral medication adherence counseling. Masivukeni-is an innovative multimedia-based, computer-driven, lay counselor-delivered intervention designed to help people living with HIV in resource-limited settings achieve optimal adherence. This pilot study examined medication adherence and key psychosocial outcomes among 55 non-adherent South African HIV+ patients, on antiretroviral therapy (ART) for at least 6 months, who were randomized to receive either Masivukeni or standard of care (SOC) counseling for ART non-adherence. At baseline, there were no significant differences between the SOC and Masivukeni groups on any outcome variables. At post-intervention (approximately 5-6 weeks after baseline), -clinic-based pill count adherence data available for 20 participants (10 per intervention arm) showed a 10 % improvement for-participants and a decrease of 8 % for SOC participants. Masivukeni participants reported significantly more positive attitudes towards disclosure and medication social support, less social rejection, and better clinic-patient relationships than did SOC participants. Masivukeni shows promise to promote optimal adherence and provides preliminary evidence that multimedia, computer-based technology can help lay counselors offer better adherence counseling than standard approaches.

    The report contains the main results in improvement of technology of water-cooled reactors that have been achieved in the USSR since the previous IWG ATPWR meeting in Helsinki, Finland, June 1988. First of all, the safety of operating reactor plants of WWER and RBMK type was greatly increased. New normative-technical documentation was revised and reissued. Introducing new ''General statements of nuclear station safety ensurance'' (OPB-88) since 1.07.1990 is of great importance. The safety analysis showed that the available WWER-1000 design may be the base one for the further development of the advanced technology for WWER that meets the requirements of safety, reliability and economical efficiency. Nowadays, development of two commercial designs of WWER is being conducted: average power, 500-600 MWe and 1000-1300 MWe. The latter one has two stages: WWER-88 (1000 MWe power, in 1990 the stage of detailed project report will be completed) and WWER-92 (1000-1300 MWe power, the concept of the design has been developed). Besides, the design of nuclear district heating plant AST-500 has been developed and its construction is underway now. The design passed an independent examination for safety requirements compliance.

    2016-09-01

    To support the implementation of the IWRM-Indonesia process in a water scarce and sanitation poor region of Central Java (Indonesia), sustainability assessments of several technology options of water supply and sanitation were carried out based on the conceptual framework of the integrative sustainability concept of the German Helmholtz association. In the case of water supply, the assessment was based on the life-cycle analysis and life-cycle-costing approach. In the sanitation sector, the focus was set on developing an analytical tool to improve planning procedures in the area of investigation, which can be applied in general to developing and newly emerging countries. Because sanitation systems in particular can be regarded as socio-technical systems, their permanent operability is closely related to cultural or religious preferences which influence acceptability. Therefore, the design of the tool and the assessment of sanitation technologies took into account the views of relevant stakeholders. The key results of the analyses are presented in this article.

  8. Measuring and improving patient safety through health information technology: The Health IT Safety Framework.

    2016-04-01

    Health information technology (health IT) has potential to improve patient safety but its implementation and use has led to unintended consequences and new safety concerns. A key challenge to improving safety in health IT-enabled healthcare systems is to develop valid, feasible strategies to measure safety concerns at the intersection of health IT and patient safety. In response to the fundamental conceptual and methodological gaps related to both defining and measuring health IT-related patient safety, we propose a new framework, the Health IT Safety (HITS) measurement framework, to provide a conceptual foundation for health IT-related patient safety measurement, monitoring, and improvement. The HITS framework follows both Continuous Quality Improvement (CQI) and sociotechnical approaches and calls for new measures and measurement activities to address safety concerns in three related domains: 1) concerns that are unique and specific to technology (e.g., to address unsafe health IT related to unavailable or malfunctioning hardware or software); 2) concerns created by the failure to use health IT appropriately or by misuse of health IT (e.g. to reduce nuisance alerts in the electronic health record (EHR)), and 3) the use of health IT to monitor risks, health care processes and outcomes and identify potential safety concerns before they can harm patients (e.g. use EHR-based algorithms to identify patients at risk for medication errors or care delays). The framework proposes to integrate both retrospective and prospective measurement of HIT safety with an organization's existing clinical risk management and safety programs. It aims to facilitate organizational learning, comprehensive 360 degree assessment of HIT safety that includes vendor involvement, refinement of measurement tools and strategies, and shared responsibility to identify problems and implement solutions. A long term framework goal is to enable rigorous measurement that helps achieve the safety

    Cerebral palsy (CP) is the most common childhood motor disability and often results in debilitating walking abnormalities, such as flexed-knee and stiff-knee gait. Current medical and surgical treatments are only partially effective in improving gait abnormalities and may cause significant muscle weakness. However, emerging artificial walking technologies, such as step-initiated, multichannel neuromuscular electrical stimulation (NMES), can substantially improve gait patterns and promote muscle strength in children with spastic CP. NMES may also be applied to specific lumbar-sacral sensory roots to reduce spasticity. Development of tablet computer-based multichannel NMES can leverage lightweight, wearable wireless stimulators, advanced control design, and surface electrodes to activate lower-limb muscles. Musculoskeletal models have been used to characterize muscle contributions to unimpaired gait and identify high muscle demands, which can help guide multichannel NMES-assisted gait protocols. In addition, patient-specific NMES-assisted gait protocols based on 3D gait analysis can facilitate the appropriate activation of lower-limb muscles to achieve a more functional gait: stance-phase hip and knee extension and swing-phase sequence of hip and knee flexion followed by rapid knee extension. NMES-assisted gait treatment can be conducted as either clinic-based or home-based programs. Rigorous testing of multichannel NMES-assisted gait training protocols will determine optimal treatment dosage for future clinical trials. Evidence-based outcome evaluation using 3D kinematics or temporal-spatial gait parameters will help determine immediate neuroprosthetic effects and longer term neurotherapeutic effects of step-initiated, multichannel NMES-assisted gait in children with spastic CP. Multichannel NMES is a promising assistive technology to help children with spastic CP achieve a more upright, functional gait. © 2017 International Center for Artificial Organs and

  10. Improvements to TAO Ocean Observations as a Result of Refresh Technology

    2016-02-01

    The Tropical Atmosphere Ocean (TAO) array has been a major observational component of El Nino Southern Oscillation (ENSO) and climate prediction research since its completion in 1994 by NOAA's Pacific Marine Environmental Laboratory (PMEL). In 2005 operational responsibility and control of the TAO array was transitioned from PMEL to the National Data Buoy Center (NDBC). As part of the transition, a project for TAO Technology Refresh was developed to address equipment obsolescence and the need for higher data throughput in real-time. Completed in 2014, the "TAO Refresh" array has met the requirements of the NOAA transition plan and added new capabilities and value. These new capabilities include a reduced latency of data and increased real-time resolution from one observation per sensor each day to 144+ observations per sensor each day. Also, improvements in NDBC data management practices resulted in the development of a new TAO Automated Statistical Quality-control (TASQ) system that provides a real-time automated quality-control method based upon 20 years of historical data. In addition, an active method for gathering actionable evidence and combating vandalism was achieved through the installation of cameras on TAO buoys. With these enhanced capabilities, the TAO Refresh array is better positioned to support timely analyses of the diurnal cycle and high frequency weather phenomena that affect climate. An added benefit of the Refresh technology is the reduced sampling error due to the temporal averaging. For example, during a recent week long vandalism event at a Refresh buoy we have found an average error of 0.24°C (±0.17) in the subsurface temperature daily average, with the maximum error of 0.67°C. Historically, due to the limitations of real-time communications, these errors were masked within the daily average. However, with today's satellite system we can retrieve the full-resolution time series in real-time and improve the quality of our data.

    Heart failure (HF) causes significant symptom burden and human suffering with considerable economic burden due to hospital readmissions. Targeted interventions to encourage and support self-management behavior is warranted. To test the proof of concept of a mobile application (HeartMapp) in improving self-care management of patients with heart failure. An exploratory inquiry used a field study strategy with purposeful sampling and constant comparative analysis to test the proof of concept of HeartMapp using The Business Model Canvas framework. A total of 125 individuals, who were identified as potential candidates to use the HeartMapp completed the interview over a seven-week period in 2016. Constant comparative analysis indicated themes that Skilled Nursing Facilities had increased readmissions. Participants from Skilled Nursing Facilities reported concern on lack of staffing, star rating, and malpractice claims. Two types of patients were identified as early adapters of technology and those in denial. Health care facilities reported challenges on transitional care, nurses struggle with engagement of patients on self-care management. To avoid readmission penalty, hospitals task home care agencies to keep the patients home for 30-days. While home care agencies rely on remote telemonitoring reported that current telemonitoring devices are costly to maintain, thus exploring novel technology. The Business Model Canvas provided directions for future testing of HeartMapp for its usability as an adjunct device in home health setting to improve self-management and enhance communication with providers, and ultimately reduce readmissions.

    Food technology transfer to rural households, based on local ingredients, is a relevant and sustainable strategy to ensure better nutrition of young children. Objective. To develop an improved mush based on local ingredients and evaluate the potential for transferring its technology to rural housewives. We developed a flour-based food using Alicom software and performed laboratory trials to evaluate its actual nutritional quality. Then we recruited housewives from each of the 27 project villages and trained them in flour production and mush preparation twice daily, 6 days a week, for 26 weeks. Mush was sampled during the training session and at weeks 4, 12, and 22 and evaluated for actual flow distance and dry matter content, which served to estimate energy density and iron and zinc contents. The laboratory trials reported average energy densities of 103 kcal/l00 g, iron contents of 2.6 mg/100 kcal, and zinc contents of 1.2 mg/100 kcal. The average (+/- SD) energy densities of the mush samples obtained during the training session and at weeks 4, 12, and 22 were 103.0 +/- 5.6, 103.3 +/- 5.2, 107.9 +/- 11.5, and 101.3 +/- 8.7 kcal/100 g, respectively. The average iron contents were 2.3 +/- 0.5, 2.3 +/- 0.5, 2.6 +/- 0.3, and 1.8 +/- 0.8 mg/ 100 kcal, respectively, and the average zinc contents were 1.6 +/- 0.1, 1.6 +/- 0.1, 1.7 +/- 0.1, and 1.6 +/- 0.2 mg/100 kcal. Developing a suitable complementary food from local ingredients and educating households in nutrition and use of local products are feasible. Such education should come with measures aimed at improving the accessibility of some ingredients to ensure feasibility and sustainability.

Pilot study. Johns Hopkins Medicine, Baltimore, MD. Primary, tertiary, and quaternary clinical care; institutional environment. Experimental group: two randomly selected postgraduate year-1 integrated training program residents per year for 2 consecutive years from the Department of Plastic and Reconstructive Surgery. traditionally trained residents from the integrated training program in the Department of Plastic and Reconstructive Surgery. Study duration: 7 years (until residents complete residency training). This assessment strategy would create large amounts of informative data on trainees, which can be cross-referenced to determine trainee progress. Assessment data would be collected continuously from all faculty surgeons. Comparisons of faculty and resident self-assessments would facilitate resident evaluations. Ease of use of the data collection structure would improve faculty evaluation compliance and timely resident case report completion. Improving the efficiency and efficacy of competency documentation is critical. Using portable technologies is an intuitive way to improve the trainee assessment process. We anticipate that this 2-pronged approach to trainee assessments would quickly provide large amounts of informative data to better assess trainee progress and inform Milestone assessments in a manner that facilitates immediate feedback. Assessments of faculty and resident satisfaction would help us further refine the assessment process as needed. If successful, this format could easily be implemented by other training programs.

    Asynchronous online training has become an increasingly popular educational format in the new era of technology-based professional development. We sought to evaluate the impact of an online asynchronous training module on the ability of medical students and emergency medicine (EM) residents to detect electrocardiogram (ECG) abnormalities of an acute myocardial infarction (AMI). We developed an online ECG training and testing module on AMI, with emphasis on recognizing ST elevation myocardial infarction (MI) and early activation of cardiac catheterization resources. Study participants included senior medical students and EM residents at all post-graduate levels rotating in our emergency department (ED). Participants were given a baseline set of ECGs for interpretation. This was followed by a brief interactive online training module on normal ECGs as well as abnormal ECGs representing an acute MI. Participants then underwent a post-test with a set of ECGs in which they had to interpret and decide appropriate intervention including catheterization lab activation. 148 students and 35 EM residents participated in this training in the 2012-2013 academic year. Students and EM residents showed significant improvements in recognizing ECG abnormalities after taking the asynchronous online training module. The mean score on the testing module for students improved from 5.9 (95% CI [5.7-6.1]) to 7.3 (95% CI [7.1-7.5]), with a mean difference of 1.4 (95% CI [1.12-1.68]) (p<0.0001). The mean score for residents improved significantly from 6.5 (95% CI [6.2-6.9]) to 7.8 (95% CI [7.4-8.2]) (p<0.0001). An online interactive module of training improved the ability of medical students and EM residents to correctly recognize the ECG evidence of an acute MI.

    Chile, a country stranding the active plate boundary between the South-American and the Nazca Plate is afflicted by recurrent earthquakes and hazardous volcanic eruptions. The strongest earthquake ever recorded occurred here, and volcanic hazards are frequent. Consequently, this area has been studied by geoscientists for many years to improve the understanding of subduction zone processes. Swath bathymetry mapping of the ocean floor has proven to bear a large potential for the interpretation of subduction-related processes, such as tectonic deformation of the marine forearc, release and migration of fluids as well as earthquake-triggered mass wasting. Multibeam bathymetry data of 16 major cruises of German, British, and Chilean research vessels recorded between 1995 and December 2010, in total more than 10,000 data files comprising about 1.6 billion soundings, have now been carefully reprocessed, compiled and merged into a unifying set of high-resolution bathymetric maps of the Chilean continental margin from latitude 40°S to 20°S. The imprint of subsurface processes on the surface morphology is well displayed in the case of the Chilean continental margin. The 3,500 km long Chilean convergent margin is not uniform, as various segments with different tectonic characteristics can be distinguished. Major factors that control margin morphology and thus the style of subduction are (1) relief and structure of the incoming oceanic plate, (2) supply of trench sediment, (3) turbidite transport within the trench, and (4) the input of terrigeneous sediments down the continental slope. A major segment boundary occurs at latitude 32°-33° S where the hotspot-related volcanic chain of Juan Fernandez is presently subducting. South of the area of ridge subduction the trench is filled with turbidites, and accretionary ridges develop across the base of the slope along most of the segment, whereas north of this boundary the turbiditic infill is reduced and subduction erosion is

    Energy saving and energy efficiency are becoming increasingly important among the many aspects within the strongly developing energy field. Energy efficiency issues touch every consumer, from a single customer up to the largest industrial customers. This project focuses on the energy efficiency of the customers groups consisting of households and office buildings. The first steps of the project dealt with literature surveys to obtain knowledge of the present energy consumptions among households and office buildings. The research partner Helsinki University of Technology focused on households and Motiva on office buildings. This part of the project was carried out as literature surveys, interviews and previous energy audits performed by Motiva. This work has been reported in separate documents. In Finland, the heating of houses takes a considerable share of the consumed energy. Heat pumps nowadays represent a popular heating alternative, especially in single-houses. The technique of heat pumps has proven to be reliable and this alternative has caught favour in the markets. The calculations showed that this technique offers a considerable energy saving potential and is applicable for new buildings as well as those renewing their heating system. On the contrary, the technologies for micro-CHP (Combined Heat and Power) were observed still to require development and their economical viability is far away. Low load operating time was problematic for the economies of all the micro-CHP technologies. In addition, the suitability of this technology for a wide application needs further investigation concerning customers, power companies and service providers. Nowadays, hourly-metered energy meters are increasingly being installed to all customers. This new data offers new approaches also concerning energy efficiency. In this project, the hourly-metered energy data was linked with specific customer data to identify the saving potential. The participating power distribution

    High technology manufacturing equipment is utilized at Los Alamos National Laboratory (LANL) to support nuclear missions. This is undertaken from concept initiation where equipment is designed and then taken through several review phases, working closely with system engineers (SEs) responsible for each of the affected systems or involved disciplines (from gasses to HVAC to structural, etc.). After the design is finalized it moves to procurement and custom fabrication of the equipment and equipment installation, including all of the paperwork involved. Not only are the engineering and manufacturing aspects important, but also the scheduling, financial forecasting, and planning portions that take place initially and are sometimes modified as the project progresses should requirements, changes or additions become necessary. The process required to complete a project of this type, including equipment installation, is unique and involves numerous steps to complete. These processes can be improved and recent work on the Direct Current Arc (DC Arc) Glovebox Design, Fabrication and Installation Project provides an opportunity to identify some important lessons learned (LL) that can be implemented in the future for continued project improvement and success.

    Due to the increased liberalisation of the power markets, nuclear power generation is being exposed to high cost reduction pressure. In this paper we highlight the role of advanced nuclear fuel technologies to reduce the fuel cycle costs and therefore increase the efficiency of nuclear power plant operation. The key factor is a more efficient utilisation of the fuel and present developments at Siemens are consequently directed at (i) further increase of batch average burnup, (ii) improvement of fuel reliability, (iii) enlargement of fuel operation margins and (iv) improvement of methods for fuel design and core analysis. As a result, the nuclear fuel cycle costs for a typical LWR have been reduced during the past decades by about US$ 35 million per year. The estimated impact of further burnup increases on the fuel cycle costs is expected to be an additional saving of US$10 - 15 million per year. Due to the fact that the fuel will operate closer to design limits, a careful approach is required when introducing advanced fuel features in reload quantities. Trust and co-operation between the fuel vendors and the utilities is a prerequisite for the common success. (authors)

    There is increasing excitement about multi-media sexually transmitted infection (STI) and HIV prevention interventions, yet there has been limited discussion of how use of multimedia technology may improve STI/HIV prevention efforts. The purpose of this paper is to describe the mechanisms through which multimedia technology may work to improve the delivery and uptake of intervention material. We present conceptual frameworks describing how multimedia technology may improve intervention delivery by increasing standardization and fidelity to the intervention material and the participant’s ability to learn by improving attention, cognition, emotional engagement, skills-building, and uptake of sensitive material about sexual and drug risks. In addition, we describe how the non-multimedia behavioral STI/HIV prevention intervention, Project WORTH, was adapted into a multimedia format for women involved in the criminal justice system and provide examples of how multimedia activities can more effectively target key mediators of behavioral change in this intervention.

In addition, we describe how the non-multimedia behavioral STI/HIV prevention intervention, Project WORTH, was adapted into a multimedia format for women involved in the criminal justice system and provide examples of how multimedia activities can more effectively target key mediators of behavioral change in this intervention.

    The use of after-action reviews (AARs) following major emergency events, such as a disaster, is common and mandated for hospitals and similar organizations. There is a recurrent challenge of identified problems not being resolved and repeated in subsequent events. A process improvement technique called a rapid improvement event (RIE) was used to conduct an AAR following a complete information technology (IT) outage at a large urban hospital. Using RIE methodology to conduct the AAR allowed for the rapid development and implementation of major process improvements to prepare for future IT downtime events. Thus, process improvement methodology, particularly the RIE, is suited for conducting AARs following disasters and holds promise for improving outcomes in emergency management.

    The Chilean Puya species constitute a monophyletic group, co-occurring in different species combinations within the country and displaying a remarkable morphological variability. Here, we studied the importance of recent hybridization and introgression in the group and reconstructed the complex inter- and intraspecific relationships. Amplified fragment length polymorphism (AFLP) analysis, including 109 accessions of all Chilean Puya species and four putative hybrids, yielded 984 characters. Three main genetic groups were revealed, with the chilensis group (P. chilensis, P. gilmartiniae, P. boliviensis) diverging first, and the alpestris (P. alpestris, P. berteroniana) and coerulea group (P. venusta, P. coerulea) forming sister groups. STRUCTURE analyses confirmed a hybrid origin of morphologically intermediate individuals, and detected several additional hybrids. Hybrids were found between the chilensis and alpestris group, and between the alpestris and coerulea group. Exclusion of hybrids improved phylogenetic reconstructions. The study demonstrates that the detection of hybrids within Bromeliaceae can be difficult based on morphological characters alone and that efficient reproductive barriers may only slowly establish, leading to hybridization between closely related sympatric species. The importance of hybridization for the rapid diversification of Puya is discussed. Copyright © 2010 Elsevier Inc. All rights reserved.

    The Diabetes Mellitus 2 treatment adherence scale version III (EATDM-III) was devised in Costa Rica. Its seven factors are family support, community organization and support, physical exercise, medical control, hygiene and self-care and assessment of physical condition. To assess the psychometric properties of the scale in Chilean patients. The results of the EATDM-III scale, applied to 274 patients with Diabetes Mellitus 2 aged 59 ± 11 years (59% women), were analyzed. Reliability, item, exploratory and confirmatory factorial analyses were carried out both in the initial and the proposed model. We propose a version of 30 items grouped in six dimensions, improving the fit indices obtained with the original scale. The review of item factor loadings shows that all are appropriate both in magnitude and statistical significance, with values between 0.46 and 0.93. Internal consistency measured by Cronbach's alpha, was 0.85 for the total scale. The adapted EATDM-III scale is reliable and can be used to assess treatment adherence in Chilean patients.

    Full Text Available Purpose – Electronic commerce or e-commerce constitutes a commercial activity on the rise. Although it has many advantages, there are several lingering factors that prevent its consolidation, such as the lack of trust of the potential consumer/user. In order to overcome that obstacle, instruments of self-regulation were created in the field of advertising. Firms that wish to distinguish themselves favorably against their competitors have the option of adopting those instruments, which play a praiseworthy role regarding the target audience and constitutes a considerable improvement of consumer rights. However, on occasions, problems arise in the market when those systems of self-regulation bind third parties that did not voluntarily enter into a contract. This paper tackles the question of if self-regulation of advertising in the net can be put in place should it affects the honor of the third party not committed with the fair-practices document. Methodology/approach/design – In this article, we will refer to the particularities that arise from a case concerning the Chilean Law no. 20,168, of 2007, on unfair competition and self-regulation of advertising in the Internet pertaining WOM, Movistar, Entel, Claro and Virgin. Findings – The Chilean Law no. 20,168, of 2007 contributes to the goal of discouraging conduct contrary to good faith or good practices in advertising in conjunction with codes of conduct that have been approved in the field related to the systems of self-regulation.

    This article provides the first height estimates for the adult population for any period of Chilean history. Based on military records, it gives an analysis of the average heights of male soldiers in the last eight decades of the colonial period, c.1730-1800s. The average height of Chilean men was around 167 centimetres, making them on average taller than men from Mexico, Italy, Portugal, Spain and Venezuela, but of a similar height to men from Sweden. However, Chilean men were clearly shorter than men in neighbouring Argentina, the USA and the UK. Chilean height remained stable during the 1740-1770s, but it declined by some 2-3 centimetres between the 1780 s and the 1800s, in line with a fall in real wages due to increasing food prices and population growth.

It consists of a brief description of the activities carried out during the project, and several Annexes that explain in a deeper way each result. SISCOM II is the main telemetry system currently in use in the Spanish underground coal mining, but it was developed ten years ago and needed a technological update, which was the objective of this project. The aims of the project were: To develop Hardware and Software for the Out stations currently used (maintenance developments) To design new hardware and software, easier to use in the current and new applications of SISCOM II Both objectives were met, although not in the way originally intended. The main results were: In the field of old Out stations update: A new set of boards for the old Out stations was developed Out station's firmware was updated for the new hardware In the field new hardware and software design: SISCOM II Supervision software was completely rewritten, and now runs under Windows 3.11/Windows 95 (Originally it ran under DOS) A new hardware configuration (the RELIA 2000), easier to assembly, install and reconfigured, together with its firmware, was developed Generally speaking the activities were carried out accordingly to the original schedule, with one exception, due to changes in the market of this type of Systems. Because of the changes, which happened by the end of the project's time span, the structure of the new hardware was somehow different to the original design, although its functionality and performance is similar or even better than those of the original one.

  16. Using modern plant breeding to improve the nutritional and technological qualities of oil crops

    Murphy Denis J.

    2014-11-01

    Full Text Available The last few decades have seen huge advances in our understanding of plant biology and in the development of new technologies for the manipulation of crop plants. The application of relatively straightforward breeding and selection methods made possible the “Green Revolution” of the 1960s and 1970s that effectively doubled or trebled cereal production in much of the world and averted mass famine in Asia. During the 2000s, much attention has been focused on genomic approaches to plant breeding with the deployment of a new generation of technologies, such as marker-assisted selection, next-generation sequencing, transgenesis (genetic engineering or GM and automatic mutagenesis/selection (TILLING, TargetIng Local Lesions IN Genomes. These methods are now being applied to a wide range of crops and have particularly good potential for oil crop improvement in terms of both overall food and non-food yield and nutritional and technical quality of the oils. Key targets include increasing overall oil yield and stability on a per seed or per fruit basis and very high oleic acid content in seed and fruit oils for both premium edible and oleochemical applications. Other more specialised targets include oils enriched in nutritionally desirable “fish oil”-like fatty acids, especially very long chain !-3 acids such as eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA, or increased levels of lipidic vitamins such as carotenoids, tocopherols and tocotrienes. Progress in producing such oils in commercial crops has been good in recent years with several varieties being released or at advanced stages of development.

    2015-01-01

    Full Text Available In order to improve human computer interaction (HCI for people with special needs, this paper presents an alternative form of interaction, which uses the iPad’s front camera and eye/head tracking technology. With this functional nature/capability operating in the background, the user can control already developed or new applications for the iPad by moving their eyes and/or head. There are many techniques, which are currently used to detect facial features, such as eyes or even the face itself. Open source bookstores exist for such purpose, such as OpenCV, which enable very reliable and accurate detection algorithms to be applied, such as Haar Cascade using very high-level programming. All processing is undertaken in real time, and it is therefore important to pay close attention to the use of limited resources (processing capacity of devices, such as the iPad. The system was validated in tests involving 22 users of different ages and characteristics (people with dark and light-colored eyes and with/without glasses. These tests are performed to assess user/device interaction and to ascertain whether it works properly. The system obtained an accuracy of between 60% and 100% in the three test exercises taken into consideration. The results showed that the Haar Cascade had a significant effect by detecting faces in 100% of cases, unlike eyes and the pupil where interference (light and shade evidenced less effectiveness. In addition to ascertaining the effectiveness of the system via these exercises, the demo application has also helped to show that user constraints need not affect the enjoyment and use of a particular type of technology. In short, the results obtained are encouraging and these systems may continue to be developed if extended and updated in the future.

    There have been enormous advances in our understanding of human learning in the past three decades. There have also been important advances in our understanding of the nature of knowledge and new knowledge creation. These advances, when combined with the explosive development of the Internet and other technologies, permit advances in educational practices at least as important as the invention of the printing press in 1460. We have built on the cognitive learning theory of David Ausubel and various sources of new ideas on epistemology. Our research program has focused on understanding meaningful learning and on developing better methods to achieve such learning and to assess progress in meaningful learning. The concept map tool developed in our program has proved to be highly effective both in promoting meaningful learning and in assessing learning outcomes. Concept mapping strategies are also proving powerful for eliciting, capturing, and archiving knowledge of experts and organizations. New technology for creating concept maps developed at the University of West Florida permits easier and better concept map construction, thus facilitating learning, knowledge capture, and local or distance creation and sharing of structured knowledge, especially when utilized with the Internet. A huge gap exists between what we now know to improve learning and use of knowledge and the practices currently in place in most schools and corporations. There are promising projects in progress that may help to achieve accelerated advances. These include projects in schools at all educational levels, including projects in Colombia, Costa Rica, Italy, Spain, and the United States, and collaborative projects with corporate organizations and distance learning projects. Results to date have been encouraging and suggest that we may be moving from the lag phase of educational innovation to a phase of exponential growth.

    Full Text Available This work discusses the development of information technology service management using cloud computing approach to improve the performance of administration system and online learning at STMIK IBBI Medan, Indonesia. The network topology is modeled and simulated for system administration and online learning. The same network topology is developed in cloud computing using Amazon AWS architecture. The model is designed and modeled using Riverbed Academic Edition Modeler to obtain values of the parameters: delay, load, CPU utilization, and throughput. The simu- lation results are the following. For network topology 1, without cloud computing, the average delay is 54  ms, load 110 000 bits/s, CPU utilization 1.1%, and throughput 440  bits/s.  With  cloud  computing,  the  average  delay  is 45 ms,  load  2 800  bits/s,  CPU  utilization  0.03%,  and throughput 540 bits/s. For network topology 2, without cloud computing, the average delay is 39  ms, load 3 500 bits/s, CPU utilization 0.02%, and throughput database server 1 400 bits/s. With cloud computing, the average delay is 26 ms, load 5 400 bits/s, CPU utilization email server 0.0001%, FTP server 0.001%, HTTP server 0.0002%, throughput email server 85 bits/s, FTP    server 100 bits/sec, and HTTP server 95  bits/s.  Thus,  the  delay, the load, and the CPU utilization decrease; but,  the throughput increases.

    2016-06-06

    While evaluation of ethical aspects in health technology assessment (HTA) has gained much attention during the past years, the integration of ethics in HTA practice still presents many challenges. In response to the increasing demand for expansion of health technology assessment (HTA) methodology to include ethical issues more systematically, this article reports on a multi-stage study that aimed at construction of a framework for improving the integration of ethics in HTA. The framework was developed through the following phases: 1) a systematic review and content analysis of guidance documents for ethics in HTA; 2) identification of factors influencing the integration of ethical considerations in HTA; 3) preparation of an action-oriented framework based on the key elements of the existing guidance documents and identified barriers to and facilitators of their implementation; and 4) expert consultation and revision of the framework. The proposed framework consists of three main components: an algorithmic flowchart, which exhibits the different steps of an ethical inquiry throughout the HTA process, including: defining the objectives and scope of the evaluation, stakeholder analysis, assessing organizational capacity, framing ethical evaluation questions, ethical analysis, deliberation, and knowledge translation; a stepwise guide, which focuses on the task objectives and potential questions that are required to be addressed at each step; and a list of some commonly recommended or used tools to help facilitate the evaluation process. The proposed framework can be used to support and promote good practice in integration of ethics into HTA. However, further validation of the framework through case studies and expert consultation is required to establish its utility for HTA practice.

    As society evolves its welfare level increases, and as a consequence the amount of municipal solid waste increases, imposing great challenges to municipal authorities. In developed countries, municipalities have established integrated management schemes to handle, treat, and dispose of municipal solid waste in an economical and environmentally sound manner. Municipalities of developing and transition countries are not exempted from the challenges involving municipal solid waste handling, but their task is not easy to accomplish since they face budget deficits, lack of knowledge, and deficiencies in infrastructure and equipment. In the northern territory of Mexico, the municipality of Durango is facing the challenge of increased volumes of waste with a lack of adequate facilities and infrastructure. This article analyses the evolution of the municipal solid waste management of Durango city, which includes actions such as proper facilities construction, equipment acquisition, and the implementation of social programmes. The World Bank, offering courses to municipal managers on landfill operation and waste management, promoted the process of knowledge and technology transfer. Thereafter, municipal authorities attended regional and some international workshops on waste management. In addition they followed suggestions of international contractors and equipment dealers with the intention to improve the situation of the waste management of the city. After a 15-year period, transfer of knowledge and technology resulted in a modern municipal solid waste management system in Durango municipality. The actual system did not reach the standard levels of an integrated waste management system, nevertheless, a functional evaluation shows clear indications that municipality actions have put them on the right pathway. © The Author(s) 2014.

    Advances in computer technologies, signal processing, analytical modeling, and the advent of wireless sensors have provided the nuclear industry with ample means to automate and optimize maintenance activities and improve safety, efficiency, and availability, while reducing costs and radiation exposure to maintenance personnel. This paper provides a review of these developments and presents examples of their use in the nuclear power industry and the financial and safety benefits that they have produced. As the current generation of nuclear power plants have passed their mid-life, increased monitoring of their health is critical to their safe operation. This is especially true now that license renewal of nuclear power plants has accelerated, allowing some plants to operate up to 60 years or more. Furthermore, many utilities are maximizing their power output through uprating projects and retrofits. This puts additional demand and more stress on the plant equipment such as the instrumentation and control (I and C) systems and the reactor internal components making them more vulnerable to the effects of aging, degradation, and failure. In the meantime, the nuclear power industry is working to reduce generation costs by adopting condition-based maintenance strategies and automation of testing activities. These developments have stimulated great interest in on-line monitoring (OLM) technologies and new diagnostic and prognostic methods to anticipate, identify, and resolve equipment and process problems and ensure plant safety, efficiency, and immunity to accidents. The foundation for much of the required technologies has already been established through 40 years of research and development (R and D) efforts performed by numerous organizations, scientists, and engineers around the world including the author. This paper provides examples of these technologies and demonstrates how the gap between some of the more important R and D efforts and end users have been filled

    Intensive arable food production systems are in need of smart solutions that combine ecological knowledge and farm technology to maximize yields while protecting natural resources. The huge diversity of soil organisms and their interactions is of crucial importance for soil functions and ecosystem services, such as organic matter incorporation and break down, nutrient mineralization, soil structure formation, water regulation and disease and pest control. Soil management decisions that take into account the soil biodiversity and associated functions are thus essential to (i) maintain soil productivity in the long term, (ii) reduce the dependency on external inputs and non-renewables such as fossil fuels, and (iii) make agroecosystems more resilient against biotic and abiotic stresses. Organic farming systems and reduced tillage systems are two approaches that aim to increase soil biodiversity and general soil quality, through improved management of organic matter but differ in their emphasis on the use of chemical inputs for crop protection or soil disturbance, respectively. In North-western Europe experience with and knowledge of reduced tillage systems is still scarce, both in conventional and organic farming. Our study targeted both conventional and organic farming and aimed at 1) documenting reduced tillage practices within different agroecological contexts in NW Europe; 2) evaluating the effects of reduced tillage systems on soil biodiversity and soil ecosystem services; 3) increase understanding of agroecological factors that determine trade-offs between different ecosystem services. Earthworm species and nematode taxa were selected as indicator organisms to be studied for their known response to soil management and effects on soil functions. Additionally, soil organic matter, physical soil parameters and processes, and crop yields have been measured across multiple sites. Data have been collected over several cropping seasons in long term field experiments

    In South America, the mesocarp flour of Prosopis species plays a prominent role as a food resource in arid areas. The aim of this work was the characterization of the phenolic antioxidants occurring in the pod mesocarp flour of Chilean Prosopis. Samples were collected in the Copiapo, Huasco and Elqui valleys from the north of Chile. The samples of P. chilensis flour exhibited a total phenolic content ranging between 0.82-2.57 g gallic acid equivalents/100 g fresh flour weight. The highest antioxidant activity, measured by the DPPH assay, was observed for samples from the Huasco valley. HPLC-MS/MS analysis allowed the tentative identification of eight anthocyanins and 13 phenolic compounds including flavonol glycosides, C-glycosyl flavones and ellagic acid derivatives. The antioxidant activity and the phenolic composition in the flour suggest that this ancient South American resource may have potential as a functional food.

    The spatial distribution of total hydrolysable amino acids (THAA) and amino acid enantiomers (D- and L-forms) was investigated in sediments underlying two contrasting Chilean upwelling regions,: at ~23°S off Antofagasta and at ~36°S off Concepcion. The contribution of amino acids to total organic...... carbon (%TAAC: 7-14%) and total nitrogen (%TAAN: 23-38%) in surface sediments decreased with increasing water depth (from 126 to 1350 m) indicating that organic matter becomes increasingly decomposed in surface sediments at greater water depth. Changes in the ratio between the protein amino acid...... aspartate and its non-protein degradation product β-alanine confirmed this observation. Furthermore, estimates of THAA mineralization showed that sedimentary amino acid reactivity decreased with both increasing water depth as well as progressive degradation status of the organic matter that was incorporated...

    Full Text Available Given the geo-physic consistency of the narrow Chilean territory, extended between volcanoes and tectonic plates, the occurrence of natural catastrophes has been diachronic in its bicentennial existence as a nation. The oral as well as the written traditions have expressed this seismic nature as an ancestral ingredient of national identity. In Neruda's vital circumstances (1904-1973 four earthquakes took place, whose semiotic aftershocks resound in his writing. Noticing the telluric fate in this fi nis terrae, the poet's voice invites us to avoid mechanical and collective forgetfulness, warning us to install in the social imagination preventive attitudes to face futures disasters.

    Full Text Available Chilean pension fund industry is largely questioned by public; therefore it becomes essential to work on a strategy to enhance brand’s credibility and positioning. This study objective is to analyze and build a brand personality scale to identify consumer’s perception. An exploratory study aided by qualitative tools was carried out to track those brand’s personality traits not considered in Latorre, Martínez and Sotelo (2016. As a result, 38 personality traits have been evidenced in the pension fund administrators industry, some of which are specific to this industrial sector, such as transparency and ambition. This study findings come to complement the five dimensions identified by Aaker (1997 and subsequently validated by Latorre, Martínez y Sotelo (2016.

    Sodium and potassium contents of 40 high-protein dietary products were determined in order to complete the Table de Composición Química se Alimentos Chilenos (Chemical Composition Table of Chilean Foods). These cations' level must be strictly controlled in diets of many renal and heart patients. In Chile, Nutritionists who are in charge of preparing these diets, do not have a national composition table related to the sodium and potassium content for most of the food products. Samples of fluid cow's milk, dried milk with different fat contents, some cheeses, hen eggs, bovine entrails, some meat derivates and several meat cuts, including bovine, pork, lamb and chicken were studied.

  13. Justified Ilegality?: Controlled clientelism by the Chilean administration

    Full Text Available The Chilean civil service is considered one of the most efficient in Latin America. However, different studies describe the informal institutions that operate between the Legislative Power and the bureaucracy to fill positions in the public administration. Although some of these clientelistic practices are against the law, they have been accepted and defended in both the political and scientific spheres. Legality is not considered an important value if certain indexes have a positive development. In this context, it is important to study how corruption and clientelism have been ignored, or hidden, through political discourses and technical reports about the situation of bureaucracy. All of this allows a better understanding of why after 20 years of administrative reforms there are damaging practices which negatively affect democracy that have not been eradicated.

  17. Bayesian spatiotemporal interpolation of rainfall in the Central Chilean Andes

    Water availability in the populous and economically significant Central Chilean region is governed by complex interactions between precipitation, temperature, snow and glacier melt, and streamflow. Streamflow prediction at daily time scales depends strongly on accurate estimations of precipitation in this predominantly dry region, particularly during the winter period. This can be difficult as gauged rainfall records are scarce, especially in the higher elevation regions of the Chilean Andes, and topographic influences on rainfall are not well understood. Remotely sensed precipitation and topographic products can be used to construct spatiotemporal multivariate regression models to estimate rainfall at ungauged locations. However, classical estimation methods such as kriging cannot easily accommodate the complicated statistical features of the data, including many 'no rainfall' observations, as well as non-normality, non-stationarity, and temporal autocorrelation. We use a separable space-time model to predict rainfall using the R-INLA package for computationally efficient Bayesian inference, using the gridded CHIRPS satellite-based rainfall dataset and digital elevation models as covariates. We jointly model both the probability of rainfall occurrence on a given day (using a binomial likelihood) as well as amount (using a gamma likelihood or similar). Correlation in space and time is modelled using a Gaussian Markov Random Field (GMRF) with a Matérn spatial covariance function which can evolve over time according to an autoregressive model if desired. It is possible to evaluate the GMRF at relatively coarse temporal resolution to speed up computations, but still produce daily rainfall predictions. We describe the process of model selection and inference using an information criterion approach, which we use to objectively select from competing models with various combinations of temporal smoothing, likelihoods, and autoregressive model orders.

  18. Diversity and activity of denitrifiers of Chilean arid soil ecosystems

    Full Text Available The Chilean sclerophyllous matorral is a Mediterranean semiarid ecosystem affected by erosion, with low soil fertility and limited by nitrogen. However, limitation of resources is even more severe for desert soils such as from the Atacama Desert, one of the most extreme arid deserts on Earth. Topsoil organic matter, nitrogen and moisture content were significantly higher in the semiarid soil compared to the desert soil. Although the most significant loss of biologically preferred nitrogen from terrestrial ecosystems occurs via denitrification, virtually nothing is known on the activity and composition of denitrifier communities thriving in arid soils. In this study, we explored denitrifier communities from two soils with profoundly distinct edaphic factors. While denitrification activity in the desert soil was below detection limit, the semiarid soil sustained denitrification activity. To elucidate the genetic potential of the soils to sustain denitrification processes we performed community analysis of denitrifiers based on nitrite reductase (nirK and nirS genes as functional marker genes for this physiological group. Presence of nirK-type denitrifiers in both soils was demonstrated but failure to amplify nirS from the desert soil suggests very low abundance of nirS-type denitrifiers shedding light on the lack of denitrification activity. Phylogenetic analysis showed a very low diversity of nirK with only three distinct genotypes in the desert soil which conditions presumably exert a high selection pressure. While nirK diversity was also limited to only few, albeit distinct genotypes, the semiarid matorral soil showed a surprisingly broad genetic variability of the nirS gene. The Chilean matorral is a shrub land plant community which form vegetational patches stabilizing the soil and increasing its nitrogen and carbon content. These islands of fertility may sustain the development and activity of the overall microbial community and of

    The objective of this study was to assess the impact of the 2010 Chilean earthquake on hospital functions and services. Hospitals functioning in a post-disaster environment must provide emergency medical care related to the event, in addition to providing standard community health services. This study focused on damage to both structural and nonstructural components, as well as to utility services. Site visits were made to every hospital in a single province (Bio-Bio). Engineers conducted damage assessments while interviews of hospital administrators were conducted. The survey was requested by the Chilean Ministry of Health (MOH) to assess the impact of the earthquake on hospital operations and facility responses to those effects. Other important regional and hospital data were gathered from hospital administrators and the MOH. Seven government hospitals were surveyed. All hospitals in the region lost communications, municipal electrical power and water for several days. All reported some physical damage although only one suffered significant structural damage. All lost some functional capacity as a result of the earthquake. The loss of telephones and cellular service was identified as the most difficult problem by administrators. An average of 3 physical areas per hospital lost some degree of functional capacity following the earthquake. Even in an earthquake-prone and very well-prepared country such as Chile hospital functions were widely disrupted by the event. The loss of hospital functions can occur even with minimal damage to the physical structure. The loss of communications can impede or halt response efforts at all levels. Hospitals should be prepared to self-sustain following a disaster for 2-3 days regardless of the level of structural damage. Understanding the details of these impacts is essential to hospital preparedness and plans for continuing services after a disaster.
