    Full Text Available Objective: To observe the conversion disorder in a neurological emergency department. Methods: It is common that the initial approach to this patients include the use of various diagnostic exams. In this series we reviewed 94 patients that arrived a neurological emergency room in a 3 year period.Results: 72 patients were females (76%, and the initial presumptive diagnosis were: neurovascular syndrome in 36 patients (38.3%, convulsive disorder in 20 patients (21.28%, and conversive disorder in 8 patients (8.51%. 82 patients had motor symptoms and 61 sensitive symptoms. 88 patients (93% required neuroimaging studies, 77 (81% patients underwent through basic biochemical panels. Other tests performed were: electroencephalogram in 12 patients (12.77%, electromyography in 11 patients (11.7%, lumbar punction in 8 patients (8.04% and regarding the medical consult in the care of these patients 11 were evaluated by 1 specialists, 35 (37.2% by 2 different specialties, 42 (44.63% patients required evaluation by 3, and 6 patients (6.38% required evaluation by 4 different specialties.Conclusions: Based on this data, we conclude that conversion disorders require a lot of resources in the emergency room and that the similarities with neurological diseases demands a complete workup including expensive diagnostic tools. However, this patients can be discharged safely without requiring hospitalization.

    2014-05-25

    Cost growth and construction delays are problems that plague many large construction projects including the construction of new Department of Energy (DOE) nuclear facilities. A study was conducted to evaluate cost growth of large DOE construction projects. The purpose of the study was to compile relevant data, consider the possible causes of cost growth, and recommend measures that could be used to avoid extreme cost growth in the future. Both large DOE and non-DOE construction projects were considered in this study. With the exception of Chemical and Metallurgical Research Building Replacement Project (CMRR) and the Mixed Oxide Fuel Fabrication Facility (MFFF), cost growth for DOE Nuclear facilities is comparable to the growth experienced in other mega construction projects. The largest increase in estimated cost was found to occur between early cost estimates and establishing the project baseline during detailed design. Once the project baseline was established, cost growth for DOE nuclear facilities was modest compared to non-DOE mega projects.

  7. Graduate student driven efforts to increase diversity of department lecture series

    Science.gov (United States)

    Bryant, R.; Keisling, B. A.

    2017-12-01

    It is well documented that women and people of color (and especially women of color) remain underrepresented in the geoscience community. As graduate students we noticed this underrepresentation in our department lecture series. Since 2013, 40% of the invited speakers were women and 5% URM, with the majority of the URM scientists coming to campus for an annual special lecture that highlights the work of black geoscientists. Our goals for the 2017-18 lecture series are the following: 1) to increase the percentage of women speakers from 40% to 50% or higher, 2) to increase the participation of URM scientists from one per year to at least one per semester, 3) to expand the established annual special lecture highlighting contributions from black geoscientists from one lecture to four, and 4) to motivate a department-wide conversation surrounding the issues and significance of inclusion and equity in our departmental geoscience community and beyond. Our focus on gender, race, and ethnicity in diversifying the lecture series unfortunately falls short of capturing the full range of perspectives from groups that are underrepresented as defined by the NSF. We see our work as a first step and hope to encourage more conversations about broader diversity. To accomplish our goals, we will seek advice and counsel from scholars in fields like Sociology and Education, as well as pursue external funding to bolster the budget allocated by our department. As graduate students, it is important for us to envision facets of our peers and ourselves reflected in the perspectives, experiences and narratives of prominent speakers brought to campus. We find it therefore important that our department lecture series, a highly visible venue, be more inclusive and representative. Our efforts show that seeking external support and setting achievable goals can lead to better representation of underrepresented groups in such spaces.

  9. Time-series animation techniques for visualizing urban growth

    Science.gov (United States)

    Acevedo, W.; Masuoka, P.

    1997-01-01

    Time-series animation is a visually intuitive way to display urban growth. Animations of landuse change for the Baltimore-Washington region were generated by showing a series of images one after the other in sequential order. Before creating an animation, various issues which will affect the appearance of the animation should be considered, including the number of original data frames to use, the optimal animation display speed, the number of intermediate frames to create between the known frames, and the output media on which the animations will be displayed. To create new frames between the known years of data, the change in each theme (i.e. urban development, water bodies, transportation routes) must be characterized and an algorithm developed to create the in-between frames. Example time-series animations were created using a temporal GIS database of the Baltimore-Washington area. Creating the animations involved generating raster images of the urban development, water bodies, and principal transportation routes; overlaying the raster images on a background image; and importing the frames to a movie file. Three-dimensional perspective animations were created by draping each image over digital elevation data prior to importing the frames to a movie file. ?? 1997 Elsevier Science Ltd.

  10. Undergraduate Research and the Growth of a Department

    2003-12-01

    According to American Institute of Physics statistics the College of Charleston's Department of Physics and Astronomy is second among all primarily undergraduate institutions in the production of physics and astronomy bachelor's degrees. A little over a decade ago the roster faculty of the department consisted of 5 physicists and 2 astronomers. Currently we have 13 filled positions including 6 astronomers and are hiring 3 additional faculty this year. What has caused this growth? While there are a number of factors, our undergraduate research program is a major one. Although we have required a "senior project" for 30 years about 15 years ago we started encouraging students to present their work at both a college wide research poster session and the annual meeting of the South Carolina Academy of Science. We also began to encourage students to begin research earlier in their careers. At about the same time we received NSF funding to operate an automatic photometric telescope in southern Arizona. This facility greatly increased the opportunities available in astronomy. A decade ago venues for student presentations were expanded to include AAS meetings as well as others. Undergraduate students, especially beginning ones, require very careful and time-consuming mentoring. In addition to funding from NSF our students have also been funded by the SC Space Grant and by internal funds. Even in the time of drastic budget cuts our president has begun funding 20 competitive summer research appointments for undergraduates as well as providing travel support for attendance at meetings. In summary, our emphasis on undergraduate research has attracted students and in turn resulted in the administration granting us additional faculty lines. The new faculty hires have been instrumental in attracting even more students. I would like to express my appreciation to my students and colleagues and to NSF for supporting our automatic telescope for the last 14 years under the following

    Migraine headaches requiring an emergency department visit due to failed outpatient rescue therapy present a significant challenge in terms of length of stay (LOS) and financial costs. Propofol therapy may be effective at pain reduction and reduce that length of stay given its pharmacokinetic properties as a short acting intravenous sedative anesthetic and pharmacodynamics on GABA mediated chloride flux. Case series of 4 patients presenting to an urban academic medical center with migraine headache failing outpatient therapy. Each patient was given a sedation dose (1 mg/kg) of propofol under standard procedural sedation precautions. Each of the 4 patients experienced dramatic reductions or complete resolution of headache severity. LOS for 3 of the 4 patients was 50% less than the average LOS for patients with similar chief complaints to our emergency department. 1 patient required further treatment with standard therapy but had a significant reduction in pain and a shorter LOS. There were no episodes of hypotension, hypoxia, or apnea during the sedations. In this small case series, sedation dose propofol appears to be effective and safe for the treatment of refractory migraines, and may result in a reduced LOS.

  13. Growth of the Female Professional in the Radiation Safety Department

    International Nuclear Information System (INIS)

    Yoon, J.

    2015-01-01

    Currently in Korea’s Nuclear Power Plants (KHNP), the number of the female staffs has been increased as planned construction of new NPPs. However the role of the female staffs in NPPs is still limited as before. Because there is the prejudice which the operating and the maintenance work is unsuitable for female owing to the risk of the radiation exposure and the physical weakness. So female staffs mostly belong to the supporting departments. In particular, the proportion of the female staffs is significantly higher in the radiation safety department among those. The ratio is 15% and is twice higher, whereas the total percentage of the female workers in KHNP is 8%. In the past, the women staffs in the radiation safety department were usually charge of the non-technical duties like the radiation exposure dose management and the education for radiation workers. Although the ratio of the women about that is still higher, nowadays, the role of the female workers tends to diversify to technical supports like the radiation protection and the radioactive waste management while increased the proportion of female employees. This trend is expected to continue for many years to come. Thus, in Korea’s NPPs, it is expected that many women will demonstrate their professionalism especially in the radiation safety department than any other departments. This presentation contains the detailed duty and trend about female staffs in the radiation safety department in Korea’s NPPs. (author)

    The primary purpose of this guide is to describe each series of records which pertains to studies of worker health and mortality funded by the U.S. Department of Energy (DOE) at the Hanford site. Additionally, the guide provides information on the location and classification of the records and how they may be accessed. History Associates Incorporated (HAI) prepared this guide as part of its work as the support services contractor for DOE`s Epidemiologic Records Inventory Project. This introduction briefly describes the Epidemiologic Records Inventory Project, HAI`s role in the project, the history of the DOE and the Hanford site, and Hanford`s organizational structure. It provides information on the methodology used to inventory and describe pertinent records stored in various onsite offices, in Hanford`s Records Holding Area (RHA), and at the Seattle Federal Records Center (SFRC). Other topics include the methodology used to produce the guide, the arrangement of the record Series descrimations, and information on accessing records repositories.

    2016-04-01

    To describe the clinical characteristics of a series of patients presenting conversion disorder in a general internal medicine ward and outpatient clinic, the arguments retained by the physicians in favour of the diagnosis, the somatic and psychiatric co-morbidities, the management and the outcome of the disorder. We report the study of 37 patients diagnosed with conversion disorder in an internal medicine department of a French university hospital over a period of 14 years. We retrospectively reviewed the charts of the patients and contacted their primary care physicians to obtain follow-up data. No structured instrument was used for the diagnosis of conversion disorder or for the assessment of psychiatric comorbidities. As expected, patients were mostly young females, although a great variety of age, gender, and socio-cultural background was observed. Motor symptoms predominated (62%). A relevant psychogenic factor was explicitly mentioned in only 43% of the cases. In many cases, organic disease was also present, and an organic cause for the symptom initially considered as conversion was suspected in 3 cases. Depressive and anxious disorders were present respectively in 38% and 35% of cases. A pain complaint was associated in half of the cases. Among patients for whom follow-up data is available, conversion symptoms persisted or recurred in 70% of cases and were associated with a poor quality of life. This case series confirms that the DSM-IV-TR criterion of "psychogenicity" (later abandoned in DSM-5) is highly problematic in clinical practice. It suggests a close relationship between conversion disorder and unexplained chronic pain. Copyright © 2015 L’Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

    2009-10-01

    We describe the effects of Lean, a process improvement strategy pioneered by Toyota, on quality of care in 4 emergency departments (EDs). Participants in 2 academic and 2 community EDs that instituted Lean as their single process improvement strategy made observations of their behavioral changes over time. They also measured the following metrics related to patient flow, service, and growth from before and after implementation: time from ED arrival to ED departure (length of stay), patient satisfaction, percentage of patients who left without being seen by a physician (2 EDs), the time from ordering to reading radiographs (1 ED), and changes in patient volume. One year post-Lean, length of stay was reduced in 3 of the EDs despite an increase in patient volume in all 4. Each observed an increase of patient satisfaction lagging behind by at least a year. The narratives indicate that the closer Lean implementation was to the original Toyota principles, the better the initial outcomes. The immediate results were also greater in the EDs in which the frontline workers were actively participating in the Lean-driven process changes. A factor that considerably affected the outcomes in the second and third year postimplementation was the level of continuous leadership commitment to Lean. Lean principles adapted to the local culture of care delivery can lead to behavioral changes and sustainable improvements in quality of care metrics in the ED. These improvements are not universal and are affected by leadership and frontline workforce engagement.

    Full Text Available Introduction: Since hoverboards became available in 2015, 2.5 million have been sold in the US. An increasing number of injuries related to their use have been reported, with limited data on associated injury patterns. We describe a case series of emergency department (ED visits for hoverboard-related injuries. Methods: We performed a retrospective chart review on patients presenting to 10 EDs in southeastern Virginia from December 24, 2015, through June 30, 2016. We used a free-text search feature of the electronic medical record to identify patients documented to have the word “hoverboard” in the record. We reported descriptive statistics for patient demographics, types of injuries, body injury location, documented helmet use, injury severity score (ISS, length of stay in the ED, and ED charges. Results: We identified 83 patients in our study. The average age was 26 years old (18 months to 78 years. Of these patients, 53% were adults; the majority were female (61.4% and African American (56.6%. The primary cause of injury was falls (91%, with an average ISS of 5.4 (0–10. The majority of injuries were contusions (37.3% and fractures (36.1%. Pediatric patients tended to have more fractures than adults (46.2% vs 27.3%. Though 20% of patients had head injuries, only one patient reported using a helmet. The mean and median ED charges were $2,292.00 (SD $1,363.64 and $1,808.00, respectively. Head injuries resulted in a significantly higher cost when compared to other injuries; median cost was $2,846.00. Conclusion: While the overall ISS was low, more pediatric patients suffered fractures compared to adults. Documented helmet use was low, yet 20% of our population had head injuries. Further investigation into proper protective gear and training is warranted.

  20. A multivariate time series approach to forecasting daily attendances at hospital emergency department

    KAUST Repository

    Kadri, Farid

    2018-02-07

    Efficient management of patient demands in emergency departments (EDs) has recently received increasing attention by most healthcare administrations. Forecasting ED demands greatly helps ED\\'s managers to make suitable decisions by optimally allocating the available limited resources to efficiently handle patient attendances. Furthermore, it permits pre-emptive action(s) to mitigate and/or prevent overcrowding situations and to enhance the quality of care. In this work, we present a statistical approach based on a vector autoregressive moving average (VARMA) model for a short term forecasting of daily attendances at an ED. The VARMA model has been validated using an experimental data from the paediatric emergency department (PED) at Lille regional hospital centre, France. The results obtained indicate the effectiveness of the proposed approach in forecasting patient demands.

    2015-11-01

    Shunt series and shunt patency studies can be performed in the emergency department (ED) to evaluate for shunt malfunction in patients with idiopathic intracranial hypertension (IIH). Here, we examine the utility of these studies in this specific patient population. We retrospectively reviewed the ED visits of all shunted patients diagnosed with IIH from 2003 to 2014. ED visits for symptoms not related to the patient's IIH were excluded from the study. Collected variables included demographics, symptoms, IIH diagnosis and treatment history, imaging findings, and management changes. Twenty-five (81%) patients had a total of 105 visits involving a shunt series, with four (3.9%) showing problems with the catheter. The majority of shunt series (n=101, 96%) showed no catheter pathology. Based on results of the shunt series alone, in 3 instances, management changes in the form of shunt revision or shunt reprogramming occurred. Of the 105 visits with a shunt series, 17 (16%) resulted in a change in management as compared to 12 out of 66 (18%) visits without a shunt series (p=0.83). Nine patients had a total of 10 visits involving a shunt patency study: five were normal, four were abnormal, and one was inconclusive. Based on findings on the shunt patency study alone, changes in management leading to shunt adjustment or revision occurred in 4 instances. Of the 10 visits with shunt patency studies, 5 resulted in a change in management as compared to 24 out of 161 visits without a shunt patency study (p=0.014). Shunt series detected catheter pathology only 3.9% of the time, and there was no difference in the rate of management changes between those patients who underwent a shunt series and those who did not. There was a significant difference in the rate of management changes in patients who received shunt patency studies as compared to those who did not. Shunt series may not be a useful screening tool to be used universally to diagnose shunt malfunction in IIH patients in

    2018-02-01

    Musculoskeletal injuries are a common presentation to the ED, with significant costs involved in the management of these injuries, variances in care within the ED and associated morbidity. A series of rapid review papers were completed to guide best practice for the assessment and management of common musculoskeletal injuries presenting to the ED. This paper presents the methodology used across the rapid reviews. PubMed, CINAHL, EMBASE, TRIP and the grey literature, including relevant organisational websites, were searched in 2015. The search was repeated consistently for each topic area (injuries of the foot and ankle, knee, hand and wrist, elbow, shoulder, lumbar spine and cervical spine). English-language primary studies, systematic reviews and guidelines that were published in the last 10 years and addressed acute musculoskeletal injury management were considered for inclusion. Data extraction of each included article was conducted, followed by a quality appraisal. The extracted data from each article was synthesised to group similar evidence together. For each rapid review, the evidence has been organised in a way that a clinician can direct their attention to a specific component of the clinical cycle of care in the ED, such as the assessment, diagnostic tests, management and follow-up considerations from ED. The series of rapid reviews are designed to foster evidence-based practice within the ED, targeting the injuries most commonly presenting. The reviews provide clinicians in EDs with rapid access to the best current evidence, which has been synthesised and organised to assist decision-making. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    The objectives of this paper is two-fold: First, to empirically investigate the effects of an enlarged number of healthy and well-educated people on economic growth in Malaysia within the Endogeneous Growth Model framework. Second, to examine the causal links between education, health and economic growth using annual time series data from 1981 to 2014 for Malaysia. Data series were checked for the time series properties by using ADF and KPSS tests. Long run co-integration relationship was investigated with the help of vector autoregressive (VAR) method. For short and long run dynamic relationship investigation vector error correction model (VECM) was applied. Causality analysis was performed through Engle-Granger technique. The study results showed long run co-integration relation and positively significant effects of education and health on economic growth in Malaysia. The reported results also confirmed a feedback hypothesis between the variables in the case of Malaysia. The study results have policy relevance of the importance of human capital (health and education) to the growth process of the Malaysia. Thus, it is suggested that policy makers focus on education and health sectors for sustainable economic growth in Malaysia.

    2017-10-01

    Abstract Otitis media (OM) is a very common disease in children, which results in a significant economic burden to the healthcare system for hospital-based outpatient departments, emergency departments (EDs), unscheduled medical examinations, and antibiotic prescriptions. The aim of this retrospective observational study is to investigate the association between climate variables, air pollutants, and OM visits observed in the 2007-2010 period at the ED of Cuneo, Italy. Measures of meteorological parameters (temperature, humidity, atmospheric pressure, wind) and outdoor air pollutants (particulate matter, ozone, nitrous dioxide) were analyzed at two statistical stages and in several specific steps (crude and adjusted models) according to Poisson's regression. Response variables included daily examinations for age groups 0-3, 0-6, and 0-18. Control variables included upper respiratory infections (URI), flu (FLU), and several calendar factors. A statistical procedure was implemented to capture any delayed effects. Results show a moderate association for temperature ( T), age 0-3, and 0-6 with P < 0.05, as well as nitrous dioxide (NO2) with P < 0.005 at age 0-18. Results of subsequent models point out to URI as an important control variable. No statistical association was observed for other pollutants and meteorological variables. The dose-response models (DLNM—final stage) implemented separately on a daily and hourly basis point out to an association between temperature (daily model) and RR 1.44 at age 0-3, CI 1.11-1.88 (lag time 0-1 days) and RR 1.43, CI 1.05-1.94 (lag time 0-3 days). The hourly model confirms a specific dose-response effect for T with RR 1.20, CI 1.04-1.38 (lag time range from 0 to 11 to 0-15 h) and for NO2 with RR 1.03, CI 1.01-1.05 (lag time range from 0 to 8 to 0-15 h). These results support the hypothesis that the clinical context of URI may be an important risk factor in the onset of OM diagnosed at ED level. The study highlights the

    The association between ambient temperature and mortality has been well documented worldwide. However, limited data are available on nonfatal health outcomes, such as emergency department visits (EDVs), particularly from China. To examine the temperature-EDV association in 12 Chinese cities; and to assess the modification effects by region, gender and age. Daily meteorological data and non-accidental EDVs were collected during 2011-2014. Poisson regression with distributed lag non-linear model was applied to examine the temperature-lag-EDV association in each city. The effect estimates were pooled using multivariate meta-analysis at the national and regional level. Stratified analyses were performed by gender and age-groups. Sensitivity analyses adjusting for air pollution and relative humidity were conducted. A total of 4,443,127 EDVs were collected from the 12 cities. Both cold and hot temperatures were associated with increased risk of EDVs, with minimum-mortality temperature located at 64th percentile of temperature. The effect of cold temperature appeared on day 2 and persisted until day 30, causing a cumulative relative risk (RR) of 1.80 (1.54, 2.11). The effect of hot temperature appeared immediately and lasted until day 3, with a cumulative RR of 1.15 (1.03, 1.29). The effect of temperature on EDVs was similar in male and female but was attenuated with increasing age. The effect of cold temperature on EDVs was greater in southern areas of the country whereas the hot effect was greater in northern cities. The association was robust to a large range of sensitivity analyses. In China, there is a U-shaped association between temperature and risk of EDVs that is independent of air pollution and humidity. The temperature-EDV association varies with latitude and age-groups but is not affected by gender. Forecasting models for hospital emergency departments may be improved if temperature is included as an independent predictor. Copyright © 2017 Elsevier Ltd. All

    Growth arrest lines can develop within the skeleton after physiological stress or trauma. They are usually evident on radiographs as transverse lines in the metaphyses and have been used in fields from palaeontology to orthopaedics. This report consists of three cases, two of which describe growth arrest lines in an intra-epiphyseal site hitherto rarely documented, and a third demonstrating their clinical application. Case 1 describes a 9-year-old who suffered a knee hyperflexion injury requiring anterior cruciate ligament and posterior cruciate ligament reattachments. She subsequently developed a marked distal femoral intra-epiphyseal arrest silhouette, as well as metaphyseal arrest lines in the femur, tibia and fibula. Case 2 describes an 8-year-old who sustained a tibial spine fracture and underwent open reduction and internal fixation. Subsequent imaging shows a further example of femoral intra-epiphyseal arrest silhouette as well as tibia and fibula metaphyseal arrest lines. Case 3 describes a 10-year-old who sustained a distal tibia fracture which was managed with open reduction and internal fixation. Subsequently the metaphyseal growth arrest line was parallel to the physis, suggesting no growth arrest (a danger with such a fracture). This case series describes two examples of rarely described intra-epiphyseal growth arrest silhouettes and demonstrates the usefulness of arrest lines when assessing for growth plate damage.

    Emergency department (ED) overcrowding is acknowledged as an increasingly important issue worldwide. Hospital managers are increasingly paying attention to ED crowding in order to provide higher quality medical services to patients. One of the crucial elements for a good management strategy is demand forecasting. Our study sought to construct an adequate model and to forecast monthly ED visits. We retrospectively gathered monthly ED visits from January 2009 to December 2016 to carry out a time series autoregressive integrated moving average (ARIMA) analysis. Initial development of the model was based on past ED visits from 2009 to 2016. A best-fit model was further employed to forecast the monthly data of ED visits for the next year (2016). Finally, we evaluated the predicted accuracy of the identified model with the mean absolute percentage error (MAPE). The software packages SAS/ETS V.9.4 and Office Excel 2016 were used for all statistical analyses. A series of statistical tests showed that six models, including ARIMA (0, 0, 1), ARIMA (1, 0, 0), ARIMA (1, 0, 1), ARIMA (2, 0, 1), ARIMA (3, 0, 1) and ARIMA (5, 0, 1), were candidate models. The model that gave the minimum Akaike information criterion and Schwartz Bayesian criterion and followed the assumptions of residual independence was selected as the adequate model. Finally, a suitable ARIMA (0, 0, 1) structure, yielding a MAPE of 8.91%, was identified and obtained as Visit t =7111.161+(a t +0.37462 a t -1). The ARIMA (0, 0, 1) model can be considered adequate for predicting future ED visits, and its forecast results can be used to aid decision-making processes. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  14. Time series in analysis of yerba-mate biennial growth modified by environment

    Rakocevic, Miroslava; Martim, Simoni Fernanda

    2011-03-01

    To assess differences in the lag-effect pattern in the relationship between yerba-mate biennial growth and environmental factors, a time-series analysis was performed. A generalized Poisson regression model was used to control time trends, temperature, growing degree days (GDD), rainfalls and night length (NL). It was hypothesized that the active growth and growth pauses in yerba-mate are controlled endogenously and modified by environment, and that genders would respond differently to environmental modifications. The patterns in the lag effect from the distributed-lag models were similar to those of time-series models with meteorological data means with lag = 0. GDD and NL were principal factors affecting biennial yerba-mate shoot elongation and the number of green leaves of females grown in monoculture, besides their significant effects on metamer emission and leaf area in males grown in monoculture. NL also had a significant influence on shoot elongation and leaf area of both genders grown in forest understorey (FUS), indicating that yerba-mate growth is synchronized by an internal clock sensitive to temperature adjustments. The morphological plasticity and the adaptation efforts of yerba-mate were more pronounced in monoculture than in FUS. Sexual dimorphism was expressed—males were more sensitive to environmental changes than females, especially in monoculture. Growth modifications were much more intense when plants were grown in a cultivation system that is less like yerba-mate natural habitat (monoculture) than in one resembling its natural habitat (FUS). Our data support the ecological specialization theory.

    Full Text Available Abstract Background Relatively few studies have been conducted of the association between air pollution and emergency department (ED visits, and most of these have been based on a small number of visits, for a limited number of health conditions and pollutants, and only daily measures of exposure and response. Methods A time-series analysis was conducted on nearly 400,000 ED visits to 14 hospitals in seven Canadian cities during the 1990s and early 2000s. Associations were examined between carbon monoxide (CO, nitrogen dioxide (NO2, ozone (O3, sulfur dioxide (SO2, and particulate matter (PM10 and PM2.5, and visits for angina/myocardial infarction, heart failure, dysrhythmia/conduction disturbance, asthma, chronic obstructive pulmonary disease (COPD, and respiratory infections. Daily and 3-hourly visit counts were modeled as quasi-Poisson and analyses controlled for effects of temporal cycles, weather, day of week and holidays. Results 24-hour average concentrations of CO and NO2 lag 0 days exhibited the most consistent associations with cardiac conditions (2.1% (95% CI, 0.0–4.2% and 2.6% (95% CI, 0.2–5.0% increase in visits for myocardial infarction/angina per 0.7 ppm CO and 18.4 ppb NO2 respectively; 3.8% (95% CI, 0.7–6.9% and 4.7% (95% CI, 1.2–8.4% increase in visits for heart failure. Ozone (lag 2 days was most consistently associated with respiratory visits (3.2% (95% CI, 0.3–6.2%, and 3.7% (95% CI, -0.5–7.9% increases in asthma and COPD visits respectively per 18.4 ppb. Associations tended to be of greater magnitude during the warm season (April – September. In particular, the associations of PM10 and PM2.5with asthma visits were respectively nearly three- and over fourfold larger vs. all year analyses (14.4% increase in visits, 95% CI, 0.2–30.7, per 20.6 μg/m3 PM10 and 7.6% increase in visits, 95% CI, 5.1–10.1, per 8.2 μg/m3 PM2.5.

    Each year, 1 million people are seen in an emergency department for seizures or epilepsy. We implemented a care management checklist for patients with frequent visits. A database was searched for patients with the highest number of emergency department visits and/or unplanned hospitalizations in 2011. Four patients were selected. A care management checklist was implemented in 2012. Compliance with the office visits, number of emergency department visits and/or hospitalizations, and the associated costs were tracked following implementation of the checklist for 2011 and 2012. These 4 epilepsy patients accounted for 46 visits in the year 2011 with associated health care costs of $380,209. Following a year using a care management checklist, the same patients accounted for 11 visits with a cost reduction of $188,130. Using a care management checklist was useful in these 4 epilepsy patients to decrease emergency department visits and/or unplanned hospitalizations. A limitation of this study is its small numbers.

  1. Mapping Mountain Pine Beetle Mortality through Growth Trend Analysis of Time-Series Landsat Data

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Disturbances are key processes in the carbon cycle of forests and other ecosystems. In recent decades, mountain pine beetle (MPB; Dendroctonus ponderosae outbreaks have become more frequent and extensive in western North America. Remote sensing has the ability to fill the data gaps of long-term infestation monitoring, but the elimination of observational noise and attributing changes quantitatively are two main challenges in its effective application. Here, we present a forest growth trend analysis method that integrates Landsat temporal trajectories and decision tree techniques to derive annual forest disturbance maps over an 11-year period. The temporal trajectory component successfully captures the disturbance events as represented by spectral segments, whereas decision tree modeling efficiently recognizes and attributes events based upon the characteristics of the segments. Validated against a point set sampled across a gradient of MPB mortality, 86.74% to 94.00% overall accuracy was achieved with small variability in accuracy among years. In contrast, the overall accuracies of single-date classifications ranged from 37.20% to 75.20% and only become comparable with our approach when the training sample size was increased at least four-fold. This demonstrates that the advantages of this time series work flow exist in its small training sample size requirement. The easily understandable, interpretable and modifiable characteristics of our approach suggest that it could be applicable to other ecoregions.

    The primary purpose of this guide is to help the DOE locate and make available information relating to the 1957 Rocky Flats fire. The records are arranged into six categories: administrative and general; facilities and equipment; production and materials handling; waste management; workplace and environmental monitoring; and employee occupational exposure and health. A brief explanation of each category follows. The administrative and general section pertains to the administration of individual contractor organizations and DOE divisions at Rocky Flats. It also contains records which encompass several different subject areas and therefore can not be placed in a single category. The facilities and equipment category relates to the routine construction and maintenance of plant buildings as well as the purchase and installation of equipment. The production and materials handling records relate primarily to the inventory and production of nuclear materials and weapons components. The waste management records series found under this heading relate to the storage, handling, treatment, and disposal of radioactive, chemical or mixed materials produced or used at Rocky Flats. The records consist mostly of waste sampling and shipment records. The workplace and environmental monitoring records series found in this section pertain to monitoring of the workplace. The section also includes records that document efforts to monitor the environment outside of buildings, either onsite or offsite. Records in this category consist of sampling data and environmental impact reports. The employee occupational exposure and health section pertains to documentation relating to the health and occupational exposures of employees and visitors at Rocky Flats. Records series consist generally of dosimeter data, radiation exposure records, and medical records. Many of the records contain personal data pertaining to individual employees and may therefore be Privacy Act systems and records.

    Nearly all living artiodactyls (even-toed ungulates) possess a derived cranial arterial pattern that is highly distinctive from most other mammals. Foremost among a suite of atypical arterial configurations is the functional and anatomical replacement of the internal carotid artery with an extensive, subdural arterial meshwork called the carotid rete. This interdigitating network branches from the maxillary artery and is housed within the cavernous venous sinus. As the cavernous sinus receives cooled blood draining from the nasal mucosa, heat rapidly dissipates across the high surface area of the rete to be carried away from the brain by the venous system. This combination yields one of the most effective mechanisms of selective brain cooling. Although arterial development begins from the same embryonic scaffolding typical of mammals, possession of a rete is typically accompanied by obliteration of the internal carotid artery. Among taxa with available ontogenetic data, the point at which the internal carotid obliterates is variable throughout development. In small-bodied artiodactyls, the internal carotid typically obliterates prior to parturition, but in larger species, the vessel may remain patent for several years. In this study, we use digital anatomical data collection methods to describe the cranial arterial patterns for a growth series of giraffe (Giraffa camelopardalis), from parturition to senescence. Giraffes, in particular, have unique cardiovascular demands and adaptations owing to their exceptional body form and may not adhere to previously documented stages of cranial arterial development. We find the carotid arterial system to be conserved between developmental stages and that obliteration of the giraffe internal carotid artery occurs prior to parturition.

    In last decades satellites are routinely used in solving large amount of Earth observation (EO) tasks. One of the phenomena that can be easily noted from EO images is the urban sprawl caused by urbanization process and formation of megacities. Two concurrent processes are observed in urban area enlargement - the loss of vegetation cover by soil sealing and the increase of impervious surfaces. The area for this specific study was selected due to its economic attractiveness and closeness to one of the biggest national parks - mountain Vitosha. Better identification of the ongoing changes in this particular area is considered to be of public interest. The basic task of this research was to trace the city growth by means of multispectral data and spectral indices and list possible reasons for the changes occurred. Important advantage in case instruments onboard satellites are used in such scenarios are the global coverage, repeatability, provision of historical data sets, and data consistency from one instrument to its successor. Other goal set in this study is establish method for better delineation of built/nobuilt areas as trade off between widely used spectral indices used for change detection in urban areas and the density of the buildings in the selected area derived by means of subpixel mixture analysis. These tasks were achieved by creating several new vector layers corresponding to shape and area of the land use change in the studied area. In the framework of this study used are the freely provided by USGS multispectral data from the series of TM/ETM+ instruments onboard Landsat satellites. The product used for tasks aforementioned is level L1T(G) radiometrically corrected and orthotransformed images that has been verified in large number of experiments and cited in numerous publications. For ground truthing several sources have been used - orthophoto images for visual inspection and CLC vector layers for years 1990, 2000, 2006 and 2012.

    The objective was to evaluate the impact of an ED clinical redesign project that involved team-based care and early senior assessment on hospital performance. This was an interrupted time series analysis performed using daily hospital performance data 6 months before and 8 months after the implementation of the clinical redesign intervention that involved Emergency Consultant-led team-based care, redistribution of ED beds and implementation of a senior nursing coordination roles in the ED. The primary outcome was the daily National Emergency Access Target (NEAT) performance (proportion of total daily ED presentations that were admitted to an inpatient ward or discharged from ED within 4 h of arrival). Secondary outcomes were daily ALOS in ED, inpatient Clinical Emergency Response System (CERS) calls and hospital mortality. Autoregressive Integrated Moving Average analysis was used to model NEAT performance. Hospital mortality was modelled using negative binomial regression. After adjusting for patient volume, inpatient admissions, ambulance, hospital occupancy, weekends ED Consultant numbers, weekends and underlying trends, there was a 17% improvement in NEAT associated with the post-intervention period (95% CI 12, 19% P performance with no evidence of an increase in clinical deterioration on inpatient wards and evidence for an improvement in hospital mortality. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

  16. beta Phase Growth and Precipitation in the 5xxx Series Aluminum Alloy System

    Science.gov (United States)

    Scotto D'Antuono, Daniel

    The 5xxx series aluminum alloys are commonly used for structural applications due to their high strength to weight ratio, corrosion resistance, and weldability. This material system is a non-heat treatable aluminum and derives its strength from a super saturation of magnesium (3%>), and from cold rolling. While these materials have many admiral properties, they can undergo a process known as sensitization when exposed to elevated temperatures (50-280°C) for extended periods of time. During this process, magnesium segregates toward the grain boundaries and forms the secondary precipitate β phase (Al3Mg2). When exposed to harsh environments such as sea water, a galvanic couple is formed between the Al matrix and the β phase precipitates. The precipitates become anodic to the matrix and preferentially dissolve leaving gaps along the boundary network, ultimately leading to stress corrosion cracking. While this problem has been known to occur for some time now, questions relating to nucleation sites, misorientation dependence, effect of prior strain, and preferred temperature regimes remain unanswered. The work contained in this thesis attempted to better understand the kinetics, growth, and misorientation dependence, of β phase precipitation using in situ transmission electron microscopy experiments which allowed for direct visualization of the precipitation process. Orientation imaging using a Nanomegas/ASTAR system (OIM in TEM) coupled with the in situ experiments, along with elemental STEM EELs mapping were used to better understand the diffusion of Mg and found low angle boundaries as potential sites for nucleation. The resulting STEM EELs experiments also showed that Mg is much more stable at the grain boundaries than previously thought. Concurrent bulk ex-situ studies were used to compare various heat treatments, as well as to failed in service material showing that the low temperature treatments yield the metastable β’ phase more readily than the

    NekNomination, also known as NekNominate, Neck and Nominate, or Neck Nomination, is a social network-based drinking game which is thought to have originated in Australia and spread all over the world between 2013 and 2014. Individuals record videos of themselves while rapidly drinking excessive quantities of alcoholic drinks (necking) and then nominate friends to outdo them within 24 hours; the videos are then posted on social media such as Facebook or YouTube. The consequences of this drinking game have been very dangerous; at least 5 people under age 30 years have died after drinking deadly cocktails, and many others have suffered from alcohol intoxication. The goal of the research is to evaluate data about clinically important acute alcohol intoxication among teenagers and young adults and inform and educate the general public, especially parents, teachers, and health workers, about the spreading craze of dangerous Internet-related behavior among today's teenagers and young people up to the age of 23 years. Patients aged 15 to 23 years with acute alcohol intoxication who came to the emergency department (ED) of 2 major hospitals in Italy from January 1, 2011, to June 30, 2014, were included in this study. Data were retrieved from prehospital and intrahospital medical records and included personal information, methods of intoxication, triage color code, date and time of access to the ED, any relevant signs and symptoms, blood alcohol concentration, and diagnosis at discharge. A total of 450 young patients (male 277/450, 61.5%, female 173/450, 38.5%; age 15 to 16 years 15/450, 3.3%, age 17 to 18 years 184/450, 40.9%, age 19 to 23 years 251/450, 55.8%) were recruited. The causes of intoxication were happy hour, binge drinking, NekNominate, eyeballing, other alcoholic games, or a mix of them. Happy hour was found to be more common among the older patients, whereas NekNominate accounted for almost half of the youngest group of hospitalizations. Eyeballing occurred in

    Among the vast variety of Saccharomyces cerevisiae strains, the BY family is particularly important because the widely used deletion collections are based on this background. Here we demonstrate that some standard growth media recipes require substantial modifications to provide optimum growth conditions for auxotrophic BY strains and to avoid growth arrest before glucose is depleted. In addition to the essential supplements that are required to satisfy auxotrophic requirements, we found the four amino acids phenylalanine, glutamic acid, serine, and threonine to be indispensable for optimum growth, despite the fact that BY is 'prototrophic' for these amino acids. Interestingly, other widely used S. cerevisiae strains, such as strains of the CEN.PK family, are less sensitive to lack of the described supplements. Furthermore, we found that the concentration of inositol in yeast nitrogen base is too low to support fast proliferation of yeast cultures until glucose is exhausted. Depletion of inositol during exponential growth induces characteristic changes, namely a decrease in glucose uptake and maximum specific growth rate, increased cell size, reduced viability, and accumulation of lipid storage pools. Thus, several of the existing growth media recipes need to be revised to achieve optimum growth conditions for BY-derived strains. © 2012 Federation of European Microbiological Societies.

    Full Text Available Abstract Background Length of stay (LOS is an important indicator of efficiency for inpatient care but it does not achieve an adequate performance if it is not adjusted for the case mix of the patients hospitalized during the period considered. After two similar studies for Internal Medicine and Surgery respectively, the aims of the present study were to search for Length of Stay (LOS predictors in an acute psychiatric department and to assess the performance of the difference: observed-predicted length of stay, as an indicator of inpatient care inefficiencies. Methods Retrospective case-series of patients discharged during 1999 from the Psychiatric Department from General Hospital "Hermanos Ameijeiras" in Havana, Cuba. The 374 eligible medical records were randomly split into two groups of 187 each. We derived the function for estimating the predicted LOS within the first group. Possible predictors were: age; sex; place of residence; diagnosis, use of electroconvulsive therapy; co morbidities; symptoms at admission, medications, marital status, and response to treatment. LOS was the dependent variable. A thorough exam of the patients' records was the basis to assess the capacity of the function for detecting inefficiency problems, within the second group. Results The function explained 37% of LOS variation. The strongest influence on LOS came from: age (p = 0.002, response to treatment (p Conclusions This study demonstrates the importance of possible predictors of LOS, in an acute care Psychiatric department. The proposed indicator can be readily used to detect inefficiencies.

  3. Temperature dependences of growth rates and carrying capacities of marine bacteria depart from metabolic theoretical predictions

    Using the metabolic theory of ecology (MTE) framework, we evaluated over a whole annual cycle the monthly responses to temperature of the growth rates (μ) and carrying capacities (K) of heterotrophic bacterioplankton at a temperate coastal site. We used experimental incubations spanning 6oC with bacterial physiological groups identified by flow cytometry according to membrane integrity (live), nucleic acid content (HNA and LNA) and respiratory activity (CTC+). The temperature dependence of μat the exponential phase of growth was summarized by the activation energy (E), which was variable (-0.52 to 0.72 eV) but followed a seasonal pattern, only reaching the hypothesized value for aerobic heterotrophs of 0.65 eV during the spring bloom for the most active bacterial groups (live, HNA, CTC+). K (i.e. maximum experimental abundance) peaked at 4 × 106 cells mL-1 and generally covaried with μbut, contrary to MTE predictions, it did not decrease consistently with temperature. In the case of live cells, the responses of μand K to temperature were positively correlated and related to seasonal changes in substrate availability, indicating that the responses of bacteria to warming are far from homogeneous and poorly explained by MTE at our site. © FEMS 2015.

    Background Nasal packs are utilized nearly by otorhinolaryngologists for controlling epistaxis and post nasal procedures. Complications have been reported due to them; therefore the use of antibiotics is a common practice among otorhinolaryngologists. Objective To detect microbiological flora associated with nasal packing and find evidence to support the benefit of systemic antibiotics with it. Method A prospective, analytical study was conducted on 51 patients presenting to the Department of ENT, KUSMS from June to September 2015 who required nasal packing. Approval of the local Institutional review committee (IRC) was taken. The mid part of the pack was collected in a sterile bottle under aseptic technique and sent to microbiology department. Specimen collection, culture, identification tests were done according to the guidelines by American Society for Microbiology. Data were collected using the individual patient records and Microsoft Office Excel 2007. Statistical analysis was performed with SPSS 16.0. Result Among the 51 cultures; 33 (64.7%) were positive. In 18 (35.3%) cultures no organism was grown. Statistical analysis did not show significance between duration of pack kept with microbial growth (p=0.051) or the type of pack kept (p=0.212) .It showed significance with foul smell of the pack to the growth (p <0.001). Conclusion Microbiological flora was associated with nasal pack. Antibiotic soaked nasal packs have lesser incidence of positive bacterial growth when compared with plain nasal packs. Nasal packs kept for less than 48 hours have lesser incidence of positive bacterial growth when compared with nasal packs kept for more than 48 hours. Therefore, administering systemic antibiotics in cases when we plan to keep the pack for longer duration is recommended.

    Full Text Available Myroxylon balsamum is in great demand in Central America as its botanical and wood properties are useful in the pharmaceutical, timber and cosmetics industries. In Colombia, it is classified as near threatened (NT due to over-exploitation for resin or wood, or habitat destruction in the department of Sucre. A guide was necessary to establish propagation practices for population restoration in natural areas. Here we quantify and analyze the germination behavior ofM. balsamum. During the germination process, testa rupture occurred 15 days after sowing; obtaining a germination percentage of 77, 2% and germination rate of 23.3 days. The coefficient of variation for variable seedling height (AP, root length (LR, number of leaves (NH and number of nodes per seedling (NN generally showed a wide dispersion, but it was greater in the variables LR y NN. This high behavioural diversity maybe due to the provenance of the seed by different mother plants, their maturity or differences in genetic and physiological characteristics.

    The role of hemodynamic forces within the embryo as biomechanical regulators for cardiovascular morphogenesis, growth, and remodeling is well supported through the experimental studies. Furthermore, clinical experience suggests that perturbed flow disrupts the normal vascular growth process as one etiology for congenital heart diseases (CHD) and for fetal adaptation to CHD. However, the relationships between hemodynamics, gene expression and embryonic vascular growth are poorly defined due to the lack of concurrent, sequential in vivo data. In this study, a long-term, time-lapse optical coherence tomography (OCT) imaging campaign was conducted to acquire simultaneous blood velocity, pulsatile micro-pressure and morphometric data for 3 consecutive early embryonic stages in the chick embryo. In conjunction with the in vivo growth and hemodynamics data, in vitro reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to track changes in transcript expression relevant to histogenesis and remodeling of the embryonic arterial wall. Our non-invasive extended OCT imaging technique for the microstructural data showed continuous vessel growth. OCT data coupled with the PIV technique revealed significant but intermitted increases in wall shear stress (WSS) between first and second assigned stages and a noticeable decrease afterwards. Growth rate, however, did not vary significantly throughout the embryonic period. Among all the genes studied, only the MMP-2 and CASP-3 expression levels remained unchanged during the time course. Concurrent relationships were obtained among the transcriptional modulation of the genes, vascular growth and hemodynamics-related changes. Further studies are indicated to determine cause and effect relationships and reversibility between mechanical and molecular regulation of vasculogenesis.

    2011-03-01

    Full Text Available This study examines the dynamic interrelationships between trade, income growth, energy consumption and CO2 emissions for G-20 economies in a framework of cointegrated vector autoregression (CVAR. Johansen's maximum likelihood procedure is used to estimate the coefficients of the cointegrated VAR. The results show that trade and income growth have a favorable effect on environmental quality for the developed G-20 member countries, while they have an adverse effect on the environment for the developing member countries. We also find that energy con- sumption tends to worsen environmental quality for both the developed and developing countries. Finally, it is found that trade and income to emission and energy causality holds for the developed countries; changes in degree of trade openness and income growth lead to corresponding changes in the rates of growth in emission and energy consumption. Emission and energy to trade and income causality, on the other hand, is found to hold for the developing countries; any shocks in emission and energy consumption cause corresponding fluctuations in income growth and trade openness.

    2011-01-01

    This paper examines the causal relationship between the electric power industry and the economic growth of Cote d'Ivoire. Using the data from 1971 to 2008, a test was conducted for the cointegration and Granger causality within an error correction model. Results from these tests reveal a bidirectional causality between per capita electricity consumption and per capita GDP. A unidirectional causality running from electricity consumption to industry value added appears in the short run. Economic growth is found to have great effects on electricity consumption and a reverse causality from electricity to economic growth may also appear. In the long run, there is a unidirectional causality between electricity and both GDP and industry value added. From these findings, we conclude that the country will be energy dependent in the long run and must therefore secure the production network from shortfalls to ensure a sustainable development path. Accordingly, government should adopt policies aimed at increasing the investment in the sector by stepping up electricity production from existing and new energy sources. - Highlights: → We analyze the electricity-growth nexus for Cote d'Ivoire using causality tests. → Short run bi-directional causality appears between electricity and GDP. → We found a unidirectional causality running from electricity to industry and GDP. → Economic activities are electricity dependent and require appropriate policies.

  15. High-resolution time series of Pseudomonas aeruginosa gene expression and rhamnolipid secretion through growth curve synchronization

    Full Text Available Abstract Background Online spectrophotometric measurements allow monitoring dynamic biological processes with high-time resolution. Contrastingly, numerous other methods require laborious treatment of samples and can only be carried out offline. Integrating both types of measurement would allow analyzing biological processes more comprehensively. A typical example of this problem is acquiring quantitative data on rhamnolipid secretion by the opportunistic pathogen Pseudomonas aeruginosa. P. aeruginosa cell growth can be measured by optical density (OD600 and gene expression can be measured using reporter fusions with a fluorescent protein, allowing high time resolution monitoring. However, measuring the secreted rhamnolipid biosurfactants requires laborious sample processing, which makes this an offline measurement. Results Here, we propose a method to integrate growth curve data with endpoint measurements of secreted metabolites that is inspired by a model of exponential cell growth. If serial diluting an inoculum gives reproducible time series shifted in time, then time series of endpoint measurements can be reconstructed using calculated time shifts between dilutions. We illustrate the method using measured rhamnolipid secretion by P. aeruginosa as endpoint measurements and we integrate these measurements with high-resolution growth curves measured by OD600 and expression of rhamnolipid synthesis genes monitored using a reporter fusion. Two-fold serial dilution allowed integrating rhamnolipid measurements at a ~0.4 h-1 frequency with high-time resolved data measured at a 6 h-1 frequency. We show how this simple method can be used in combination with mutants lacking specific genes in the rhamnolipid synthesis or quorum sensing regulation to acquire rich dynamic data on P. aeruginosa virulence regulation. Additionally, the linear relation between the ratio of inocula and the time-shift between curves produces high-precision measurements of

    2009-12-01

    Full Text Available Purpose: Angiosarcoma of the breast is a rare, malignant tumor for which little is known regarding prognostic indicators and optimal therapeutic regimens. To address this issue, we performed a retrospective analysis of breast angiosarcoma cases seen at Stanford University along with immunohistochemical analysis for markers of angiogenesis. Methods: Breast angiosarcoma cases seen between 1980 and 2008 were examined. Viable tissue blocks were analyzed for expression of vascular endothelial growth factor and its receptors. Results: A total of 16 cases were identified. Data was collected regarding epidemiology, treatment, response rates, disease-free survival, and the use of various imaging modalities. Five tissue blocks remained viable for immunohistochemical analysis. Vascular endothelial growth factor-A was positively expressed in 3 of these samples. Conclusion: Angiosarcoma of the breast is an aggressive malignancy with a propensity for both local recurrence and distant metastases. Angiogenesis inhibition may represent a novel therapeutic modality in this rare, vascular malignancy.

    The objective of this research study is to assess the capability of time-series of MODIS imagery to provide information suitable for enhancing the understanding of the temporal cycles shown by the abnormal growth of the floating macrophytes in order to support monitoring and management action of Lake Victoria water resources. The proliferation of invasive plants and aquatic weeds is of growing concern. Starting from 1989, Lake Victoria has been interested by the high infestation of water hyacinth with significant socio-economic impact on riparian populations. In this paper, we describe an approach based on the time-series of MODIS to derive the temporal behaviour, the abundance and distribution of the floating macrophytes in the Winam Gulf (Kenyan portion of the Lake Victoria) and its possible links to the concentrations of the main water constituencies. To this end, we consider the NDVI values computed from the MODIS imagery time-series from 2000 to 2009 to identify the floating macrophytes cover and an appropriate bio-optical model to retrieve, by means of an inverse procedure, the concentrations of chlorophyll a, coloured dissolved organic matter and total suspended solid. The maps of the floating vegetation based on the NDVI values allow us to assess the spatial and temporal dynamics of the weeds with high time resolution. A floating vegetation index (FVI) has been introduced for describing the weeds pollution level. The results of the analysis show a consistent temporal relation between the water constituent concentrations within the Winam Gulf and the FVI, especially in the proximity of the greatest proliferation of floating vegetation in the last 10 years that occurred between the second half of 2006 and the first half of 2007.The adopted approach will be useful to implement an automatic system for monitoring and predicting the floating macrophytes proliferation in Lake Victoria.

    Vascular endothelial growth factor plays major role in ocular angio genesis and retinal edema production and is a step forward in the management of ocular neovascularization and retinal edematous pathologies. To determine the efficacy and safety of intra-vitreal Avastin (Bevacizumab) in cases having central retinal vein occlusion. All patients with central retinal occlusion occurring in the past 3 months and seen between the study period were included in the study. Diagnosis of central retinal vein occlusion was made clinically by slit lamp biomicroscopy with 78D examination Patients who had received any treatment for and eyes which already had developed Anterior Segment Neovascularization, Neovascularization elsewhere or Neovascularization on disc at presentation were excluded. Dose of 0.05 ml (1.25mg) of Avastin (Bevacizumab) was used as intra vitreal injection every month for 3 months in cases that presented within a month of occlusion and less injections were given in dose presenting later. Follow-up was done at 30th, 60th, 90th and 120th day after the onset of disease. Visual outcome was defined as Snellen's or LogMar Best Corrected Visual Acuity at final follow up, of 120th day, compared to the visual acuity at presentation. Data were analyzed by SPSS version 17. Total of 17 eyes of 17 patients were included in this study. Eleven (64.7%) patients were males while 6(35.3%) were females. Total of 40 intra-vitreal injections of Avastin were given to patients with a mean of 2.35 injections per eye. Good visual outcome was achieved in 10(58.8%) eyes, while 7(41.2%) had stable visual outcome. Mean initial Best Corrected Visual Acuity (LogMar) in all 17 eyes was 1.79(SD+0.87) which significantly improved to a mean of 1.18 (SD+0.77) at final follow up. Mean improvement in Best Corrected Visual Acuity (LogMar) after paired sample test in all patients at final follow up on day 120 was 0.61(SD+0.84).

    Urban areas only covers 2% of the Earth's land area, but more than half of the global population now live in urban areas, and this proportion is expected to increase in the coming decades. Urban areas contribute significantly to climate change from the fossil fuels used for electricity generation, transport and industrial. Already, the intensive burning of carbon fuels in the world's urban areas accounts for some 70 percent of global greenhouse gas emissions. The objectives of this study are to using grid square cells method to investigate the spatial and temporal dynamics of urban growth in 50 global cities using Landsat ETM/TM imagery from 1985 to 2011. Furthermore, to provide base data for measuring urban greenhouse gas emissions. First, MLC classification method was used to produce land cover maps (6 to 11 land cover categories) by using Landsat images from 1985's, 1993's, and 2007's; To smooth the analysis, we merged similar categories of land-cover types on the land-cover maps into six main categories: Forest, Cropland, Grassland, Wetlands, Settlements, and Other land. Then, we overlaid the reclassified images on the 1 km2 grid cells to compute for each cell the percentage of the six land-cover types within it and stored the results in a new attribute table. When calculating the percentage of a land-cover type within a cell, we divided the sum of the land-cover-type area by the area of the cell. Finally, we calculated the correlation coefficients of the land-cover categories based on the 1 km2 grid square cells to investigate the relationship between land cover changes based on grid square cells for three intervals (i.e. around 1985, around 1993, and around 2007). Change analysis unveiled large changes in land cover and land use have occurred from 1985's to 2007's. The urban expansion type is difference from each other. For example, in USA, people tend to live in low density single-family homes and commute by car to work. In contrast, in Japan, the high

    Suicide-related emergency department (ED) visits by children are increasing in tandem with suicide-related Internet content. Following the announcement of Amanda Todd's suicide, her YouTube video received widespread views, providing an opportunity to explore this association. Our research question was: Among Ontario children age 11-17 years, was the release of Amanda Todd's YouTube video following her death announcement in October 2012 associated with an increase in average monthly ED visit rates for suicide-related diagnoses? We performed an interrupted time series analysis from April 2002 to December 2013, with the primary outcome as a composite of the average monthly rate of initial ED visits for suicidal ideation, intentional self-poisoning, and intentional self-harm. Secondary outcomes were average monthly rates of intensive care unit (ICU) admission and death resulting from the index visit. There was a statistically significant increase in the monthly ED visit rate for the composite outcome (p = 0.02) and death or ICU admission (p = 0.006) from April 2002 to December 2013. There was no significant change in ED visit rate for the composite outcome before and after the announcement of Amanda Todd's death, overall (119.8 versus 219.2 respectively, p = 0.5), among females (167.4 versus 316.8 respectively, p = 0.47) or among males (74.7 versus 116.9 respectively, p = 0.33). Ontario ED visits for suicide-related diagnoses in 11-17 year olds increased from 2002 to 2013. However, the increase from October 2012 to December 2013 could not be attributed to a highly publicized adolescent suicide. Our findings suggest that suicide-related Internet content is not associated with the increase in ED visits for suicidal behaviour.

    In Brazil, many cities are surrounded by sugar cane plantations, and when these plantations are burnt prior to harvesting, millions of people are exposed to the smoke from these fires from May to November every year. A daily time-series regression analysis was conducted in a city located in the sugar cane plantation region of São Paulo State, Brazil, between 1 February 2005 and 31 July 2007. The percentage increase in the number of pneumonia-related emergency department visits (PEDV) associated with a 10 µg/m(3) increase in the total suspended particles (TSP) concentration was measured, including any effects that were delayed for up to 6 days. A total of 1505 PEDV (a median of two events per day) were analysed. During the burning period, there was an acute effect that began on the day of exposure and remained for 2 days. An increase of 6% (95% CI 2.4 to 9.9) in PEDV was observed for the 2 days following the TSP increase. This pattern and the size of the effect were similar to those observed for the whole period and also during the non-burning period. Increases in TSP concentrations were found to be associated with increased PEDV in a region affected by air pollution from sugar cane burning. This finding reinforces the need for polices and efforts to ban sugar cane burning prior to harvesting. Published by the BMJ Publishing Group Limited.

    The direct and indirect health effects of increasingly warmer temperatures are likely to further burden the already overcrowded hospital emergency departments (EDs). Using current trends and estimates in conjunction with future population growth and climate change scenarios, we show that the increased number of hot days in the future can have a considerable impact on EDs, adding to their workload and costs. The excess number of visits in 2030 is projected to range between 98-336 and 42-127 for younger and older groups, respectively. The excess costs in 2012-13 prices are estimated to range between AU$51,000-184,000 (0-64) and AU$27,000-84,000 (65+). By 2060, these estimates will increase to 229-2300 and 145-1188 at a cost of between AU$120,000-1,200,000 and AU$96,000-786,000 for the respective age groups. Improvements in climate change mitigation and adaptation measures are likely to generate synergistic health co-benefits and reduce the impact on frontline health services.

    Objectives The aim of the present study was to describe trends in and age and gender distributions of presentations of older people to Australian emergency departments (EDs) from July 2006 to June 2011, and to develop ED utilisation projections to 2050. Methods A retrospective analysis of data collected in the National Non-admitted Patient Emergency Department Care Database was undertaken to assess trends in ED presentations. Three standard Australian Bureau of Statistics population growth models, with and without adjustment for current trends in ED presentation growth and effects of climate change, were examined with projections of ED presentations across three age groups (0-64, 65-84 and ≥85 years) to 2050. Results From 2006-07 to 2010-11, ED presentations increased by 12.63%, whereas the Australian population over this time increased by only 7.26%. Rates of presentation per head of population were greatest among those aged ≥85 years. Projections of ED presentations to 2050 revealed that overall ED presentations are forecast to increase markedly, with the rate of increase being most marked for older people. Conclusion Growth in Australian ED presentations from 2006-07 to 2010-11 was greater than that expected from population growth alone. The predicted changes in demand for ED care will only be able to be optimally managed if Australian health policy, ED funding instruments and ED models of care are adjusted to take into account the specific care and resource needs of older people. What is known about the topic? Rapid population aging is anticipated over coming decades. International studies and specific local-level Australian studies have demonstrated significant growth in ED presentations. There have been no prior national-level Australian studies of ED presentation trends by age group. What does this paper add? The present study examined national ED presentation trends from July 2006 to June 2011, with specific emphasis on trends in presentation by age

    Full Text Available Abstract Background From January 30-February 6, 2011, New South Wales was affected by an exceptional heat wave, which broke numerous records. Near real-time Emergency Department (ED and ambulance surveillance allowed rapid detection of an increase in the number of heat-related ED visits and ambulance calls during this period. The purpose of this study was to quantify the excess heat-related and all-cause ED visits and ambulance calls, and excess all-cause mortality, associated with the heat wave. Methods ED and ambulance data were obtained from surveillance and administrative databases, while mortality data were obtained from the state death registry. The observed counts were compared with the average counts from the same period from 2006/07 through 2009/10, and a Poisson regression model was constructed to calculate the number of excess ED visits, ambulance and deaths after adjusting for calendar and lag effects. Results During the heat wave there were 104 and 236 ED visits for heat effects and dehydration respectively, and 116 ambulance calls for heat exposure. From the regression model, all-cause ED visits increased by 2% (95% CI 1.01-1.03, all-cause ambulance calls increased by 14% (95% CI 1.11-1.16, and all-cause mortality increased by 13% (95% CI 1.06-1.22. Those aged 75 years and older had the highest excess rates of all outcomes. Conclusions The 2011 heat wave resulted in an increase in the number of ED visits and ambulance calls, especially in older persons, as well as an increase in all-cause mortality. Rapid surveillance systems provide markers of heat wave impacts that have fatal outcomes.

    The terrestrial carbon cycle is perturbed when disturbances remove leaf biomass from the forest canopy during the growing season. Changes in foliar biomass arise from defoliation caused by insects, disease, drought, frost or human management. As ephemeral disturbances, these often go undetected and their significance to models that predict forest growth from climatic drivers remains unknown. Here, we seek to distinguish the roles of weather vs. canopy disturbance on forest growth by using dense Landsat time-series to quantify departures in mean phenology that in turn predict changes in leaf biomass. We estimated a foliar biomass index (FBMI) from 1984-2016, and predict plot-level wood growth over 28 years on 156 tree-ring monitoring plots in Minnesota, USA. We accessed the entire Landsat archive (sensors 4, 5 & 7) to compute FBMI using Google Earth Engine's cloud computing platform (GEE). GEE allows this pixel-level approach to be applied at any location; a feature we demonstrate with published wood-growth data from flux tower sites. Our Bayesian models predicted biomass changes from tree-ring plots as a function of Landsat FBMI and annual climate data. We expected model parameters to vary by tree functional groups defined by differences in xylem anatomy and leaf longevity, two traits with linkages to phenology, as reported in a recent review. We found that Landsat FBMI was a surprisingly strong predictor of aggregate wood-growth, explaining up to 80% of annual growth variation for some deciduous plots. Growth responses to canopy disturbance varied among tree functional groups, and the importance of some seasonal climate metrics diminished or changed sign when FBMI was included (e.g. fall and spring climatic water deficit), while others remained unchanged (current and lagged summer deficit). Insights emerging from these models can clear up sources of persistent uncertainty and open a new frontier for models of forest productivity.

    The production of lignocellulosic-derived biofuels is a highly promising source of alternative energy, but it has been constrained by the lack of a microbial platform capable to efficiently degrade this recalcitrant material and cope with by-products that can be toxic to cells. Species that naturally grow in environments where carbon is mainly available as lignin are promising for finding new ways of removing the lignin that protects cellulose for improved conversion of lignin to fuel precursors. Enterobacter lignolyticus SCF1 is a facultative anaerobic Gammaproteobacteria isolated from tropical rain forest soil collected in El Yunque forest, Puerto Rico under anoxic growth conditions with lignin as sole carbon source. Whole transcriptome analysis of SCF1 during E.lignolyticus SCF1 lignin degradation was conducted on cells grown in the presence (0.1%, w/w) and the absence of lignin, where samples were taken at three different times during growth, beginning of exponential phase, midexponential phase and beginning of stationary phase. Lignin-amended cultures achieved twice the cell biomass as unamended cultures over three days, and in this time degraded 60% of lignin. Transcripts in early exponential phase reflected this accelerated growth. A complement of laccases, aryl-alcohol dehydrogenases, and peroxidases were most up-regulated in lignin amended conditions in mid-exponential and early stationary phases compared to unamended growth. The association of hydrogen production by way of the formate hydrogenlyase complex with lignin degradation suggests a possible value added to lignin degradation in the future.

    Full Text Available In order to evaluate the effect of intercropping with replacement and additive series for hemp (Cannabis sativa L. and sesame (Sesamum indicum L., a field experiment was conducted during growing season 2006-07 at the Agricultural Research Station of Ferdowsi University of Mashhad, Iran. A randomized complete block design with three replications was used. Treatments included different combinations of intercropping with replacement (75%sesame+ 25% hemp, 25%sesame+ 75% hemp, 50%sesame+ 50% hemp and additive (50%sesame+ 100% hemp and 100%sesame+ 50% hemp series and their monoculture. Results indicated that the highest and the lowest leaf area index (LAI and dry matter (DM accumulation of hemp were observed in 50% sesame+ 50% hemp (2.99 and 1921.7 g.m-2 and 50% sesame +100% hemp (1.06 and 929 g.m-2, respectively. The highest and the lowest LAI and DM accumulation of sesame were observed in monoculture (1.34 and 551.27 g.m-2 and 50%sesame+ 100% hemp (0.23 and 51.73 g.m-2, respectively. The maximum crop growth rate (CGR of hemp and sesame were observed in 50% sesame+ 50% hemp (76.58 gm-2day-1 and monoculture (22.78 gm-2day-1, respectively. It seems that the intercropped sesame with hemp reduced the growth indices of sesame due to increasing shading on it and decreasing the absorption of radiation.

    The lagerpetid Dromomeron romeri and the theropod Tawa hallae are two dinosauromorphs from the Norian (Upper Triassic) of the Chinle Formation, situated in New Mexico, USA. However, a recent study suggests the inclusion of the holotype of D. romeri (GR 218) and paratype (GR 155) and referred (GR 235) specimens of T. hallae in an ontogenetic series of a single species. The specimens GR 218 and GR 155 include just an isolated femur, while GR235 includes femora, pelvis and tail. The inclusion of the specimens in an unique ontogenetic series relies on the putative immature condition and plastic deformation of the specimen GR 218. However, as observed here, the disparity between the femora of D. romeri and T. hallae is considerably higher than those expected from the ontogenetic variance in dinosauromorphs. In addition, D. romeri shares an unique suite of traits with Dromomeron gigas, a species known from a mature specimen. Therefore, the high disparity between D. romeri and T. hallae, lack of traits shared solely between the three femora, and a suite of traits shared between D. romeri and D. gigas, precludes the inclusion of the three femora from Hayden Quarry in a growth series of a single taxon.

    A reference staging series of 18 morphological stages of laboratory reared lake whitefish Coregonus clupeaformis is provided. The developmental processes of blastulation, gastrulation, neurulation as well as development of the eye, circulatory system, chromatophores and mouth are included and accompanied by detailed descriptions and live imaging. Quantitative measurements of embryo size and mass were taken at each developmental stage. Eggs were 3·19 ± 0·16 mm (mean ± s.d.) in diameter at fertilization and embryos reached a total length (LT ) of 14·25 ± 0·41 mm at hatch. Separated yolk and embryo dry mass were 0·25 ± 0·08 mg and 1·39 ± 0·17 mg, respectively, at hatch. The effects of two common preservatives (formalin and ethanol) were examined throughout development and post hatch. Embryo LT significantly decreased following fixation at all points in development. A correction factor to estimate live LT from corresponding fixed LT was determined as live LT = (fixed LT )(1·025) . Eye diameter and yolk area measurements significantly increased in fixed compared with live embryos up to 85-90% development for both measurements. The described developmental stages can be generalized to teleost species, and is particularly relevant for the study of coregonid development due to additionally shared developmental characteristics. The results of this study and staging series are therefore applicable across various research streams encompassing numerous species that require accurate staging of embryos and descriptions of morphological development. © 2015 The Fisheries Society of the British Isles.

    Placental growth factor (PlGF) has been suggested as a possible biomarker for major placenta-related disorders such as preeclampsia and intrauterine growth restriction. However, experimental findings suggest that PlGF concentrations may be influenced by other factors besides the placenta. In the present study, we examined how acute fetal injury affects PlGF concentrations in maternal circulation. We therefore monitored PlGF concentrations in maternal circulation before and after feticide. A prospective comparative study was performed. Blood samples were drawn prospectively between January and July 2012, before and after feticide at predetermined time points in relation to the procedure (0, 30, 60, and 120 min). The levels of lactate dehydrogenase (LDH) in the maternal circulation were measured to detect acute tissue damage. PlGF concentrations were measured by standard human ELISA. Following feticide (60 and 120 min), PlGF concentrations decreased significantly compared to the concentrations before feticide. LDH concentrations did not change before and after feticide. Our finding, along with the detailed review of the literature described in our work, supports a new concept in which primary fetal distress can affect PlGF concentration in maternal circulation.

    The Latin American and Caribbean region - comprising Mexico, Central and South America, and the Caribbean - is relatively well endowed with energy resources, although the distribution of these resources is uneven across countries. The region produces more energy than it consumes, and the surplus energy, which amounts to 3.6 million barrels of oil equivalent per day (boe/d), is mostly oil. While the region`s total oil (crude and products) exports decreased from 4.4 million barrels per day (b/d) in 1981 to 3.8 million b/d in 1992, its net oil exports increased from about 1.6 million b/d in 1981 to 2.8 million b/d in 1992. In 1993, the surplus oil in Latin America and the Caribbean remained at 2.8 million b/d. This report analyzes the key issues of the Latin American and Caribbean energy industry and presents the future outlook for oil, gas, coal, hydroelectricity, and nuclear power developments in the region. In addition, the status of biomass energy, geothermal, and other noncommercial energy in the region will be briefly discussed in the context of overall energy development. The rest of the report is organized as follows: Section II assesses the current situation of Latin American and Caribbean energy production and consumption, covering primary energy supply, primary energy consumption, downstream petroleum sector development, and natural gas utilization. Section III presents the results of our study of future energy growth in Latin America. Important hydrocarbons policy issues in the region are discussed in Section IV, and a summary and concluding remarks are provided in Section V.

    Full Text Available Burkina Faso ranges amongst the fastest growing countries in the world with an annual population growth rate of more than three percent. This trend has consequences for food security since agricultural productivity is still on a comparatively low level in Burkina Faso. In order to compensate for the low productivity, the agricultural areas are expanding quickly. The mapping and monitoring of this expansion is difficult, even on the basis of remote sensing imagery, since the extensive farming practices and frequent cloud coverage in the area make the delineation of cultivated land from other land cover and land use types a challenging task. However, as the rapidly increasing population could have considerable effects on the natural resources and on the regional development of the country, methods for improved mapping of LULCC (land use and land cover change are needed. For this study, we applied the newly developed ESTARFM (Enhanced Spatial and Temporal Adaptive Reflectance Fusion Model framework to generate high temporal (8-day and high spatial (30 m resolution NDVI time series for all of Burkina Faso for the years 2001, 2007, and 2014. For this purpose, more than 500 Landsat scenes and 3000 MODIS scenes were processed with this automated framework. The generated ESTARFM NDVI time series enabled extraction of per-pixel phenological features that all together served as input for the delineation of agricultural areas via random forest classification at 30 m spatial resolution for entire Burkina Faso and the three years. For training and validation, a randomly sampled reference dataset was generated from Google Earth images and based on expert knowledge. The overall accuracies of 92% (2001, 91% (2007, and 91% (2014 indicate the well-functioning of the applied methodology. The results show an expansion of agricultural area of 91% between 2001 and 2014 to a total of 116,900 km². While rainfed agricultural areas account for the major part of this

  5. Evaluation of Growth and Species Composition of Weeds in Maize-Cowpea Intercropping based on Additive Series under Organic Farming Condition

    2016-11-01

    Full Text Available Introduction Weeds are main factors reducing crops yield, especially under organic farming conditions (. It has been reported that weed populations are more in organic farming compared to conventional cropping systems, resulting in more reduction of growth and yield. Although the chemical control is a fast and effective way for controlling weed populations, some negative impacts of the recent weed management on public health and the natural environment, increased the concerns of using weed chemical compositions. Thus, non-chemical weed control is in high importance. Intercropping, an agronomical operation in which two or more crops are grown simultaneously in the same field, is one of the most important methods for increasing biodiversity in agricultural ecosystems (Amosse et al., 2013; Rostami et al., 2009; Yuan-Quan et al., 2012. Therefore, the current research was aimed to evaluate the possible non chemical controlling of weeds in a maize-cowpea intercropping system. Materials and methods A field experiment was conducted in the north of Khuzestan during the growing season 2013-2014. The experiment was based on a randomized complete block design with three replications. Maize and cowpea were planted in two sole crop systems and four intercropping systems based on an additive series, including T1:100 percent maize+25 percent cowpea, T2: 100 percent maize+50 percent cowpea, T3: 100 percent maize+75 percent cowpea and T4: 100 percent maize+100 percent cowpea. No chemical materials (fertilizer and pesticide were used during growing season. Environmental usage by intercropping patterns was evaluated by measuring photosynthetically active radiations (PAR (mean of five points in each plot, selected randomly and soil moisture content at three stages. At harvest time, all plants of each plot were harvested and grouped and weighed according to their species type. Complementary effect of intercropping in using environmental resources was calculated using

  13. Some study on the growth properties of entire functions represented by vector valued Dirichlet series in the light of relative Ritt orders

    Directory of Open Access Journals (Sweden)

    Sanjib Datta

    2016-02-01

    Full Text Available For entire functions, the notions of their growth indicators such as Ritt order are classical in complex analysis. But the concepts of relative Ritt order of entire functions and as well as their technical advantages of not comparing with the growths of $exp exp z$ are not at all known to the researchers of this area. Therefore the studies of the growths of entire functions in the light of their relative Ritt order are the prime concern of this paper. Actually in this paper we establish some newly developed results related to the growth rates of entire functions on the basis of their relative Ritt order (respectively, relative Ritt lower order.

    Coban, Guersan; Bueyueklue, Ali H.

    2009-01-01

    This study aims to expose a possible dynamic structure and nonlinear relationship in exchange rates. Specifically, the analysis derives on the filtered version of USDTRY daily log returns, where TRY stands for the New Turkish Lira with respect to the US Dollar (USD) between August 2001 and February 2007. A carefully applied projective filtering methodology removed most of the noise contaminant. The computation of correlation dimension and Largest Lyapunov Exponent (LLE) supported by the surrogate data testing procedure showed that the nature of the governing dynamics of the filtered series has a significantly different behavior from a stochastic system. All computations support the evidence of deterministic chaos in the reconstructed phase space of the filtered USDTRY log return series.

    Kuo, Karen Y; Kwong, Bernice; Rahman, Zakia

    2017-10-01

    The advent of targeted chemotherapy has led to the emergence of new dermatologic toxicities. We sought to use lasers and light devices to treat recalcitrant cutaneous adverse effects related to cancer treatment. Three stage III or IV cancer patients with cutaneous complications due to epidermal growth factor receptor (EGFR) inhibitors were treated with melanin and vascular-specific laser and light technologies. Two patients reported reduction in papulopustular eruption following pulse dye laser (PDL) treatment. Two patients noted reduction in hair growth following intense pulsed light (IPL) and/or Alexandrite laser treatments. One patient was treated with both the PDL and IPL and reported improvement of both EGFR-induced hypertrichosis and papulopustular eruption. Laser and light devices targeting melanin and hemoglobin can be utilized to mitigate the cutaneous adverse effects associated with EGFR inhibitors in patients who have failed traditional therapies. This represents a new option for the cancer patient who is suffering from chemotherapy-induced side effects.

    The objective of this proof-of-principle study was to examine the potential for improved bone regenerative outcomes in maxillary sinus augmentation procedures when recombinant human platelet-derived growth factor BB (0.3 mg/mL) is combined with particulate anorganic bovine bone mineral. The surgical outcomes in all treated sites were uneventful at 6 to 8 months, with sufficient regenerated bone present to allow successful placement of maxillary posterior implants. Large areas of dense, well-formed lamellar bone were seen throughout the intact core specimens in more than half of the grafted sites. Abundant numbers of osteoblasts were noted in concert with significant osteoid in all sites, indicating ongoing osteogenesis. A number of cores demonstrated efficient replacement of the normally slowly resorbing anorganic bovine bone mineral matrix particles with newly formed bone when the matrix was saturated with recombinant human platelet-derived growth factor BB.

  4. Evaluation of Whole Tree Growth Increment Derived from Tree-Ring Series for Use in Assessments of Changes in Forest Productivity across Various Spatial Scales

    Directory of Open Access Journals (Sweden)

    Juha M. Metsaranta

    2016-12-01

    Full Text Available The inherent predictability of inter-annual variation in forest productivity remains unknown. Available field-based data sources for understanding this variability differ in their spatial resolution, temporal resolution, and typical units of measure. Nearly all other tree and forest characteristics are in practice derived from measurements of diameter at breast height (DBH. Therefore, diameter increment reconstructed annually from tree-ring data can be used to estimate annual growth increments of wood volume, but the accuracy and precision of these estimates requires assessment. Annual growth estimates for n = 170 trees sampled for whole stem analysis from five tree species (jack pine, lodgepole pine, black spruce, white spruce, and trembling aspen in Western Canada were compared against increments derived from breast height measurements only. Inter-annual variability of breast height and whole tree growth increments was highly correlated for most trees. Relative errors varied by species, diameter class, and the equation used to estimate volume (regional vs. national. A simple example of the possible effect of this error when propagated to the stand level is provided.

  15. Latest Rate, Extent, and Temporal Evolution of Growth Faulting over Greater Houston Region Revealed by Multi- Band InSAR Time-Series Analysis

    Science.gov (United States)

    Qu, F.; Lu, Z.; Kim, J. W.

    2017-12-01

    Growth faults are common and continue to evolve throughout the unconsolidated sediments of Greater Houston (GH) region in Texas. Presence of faults can induce localized surface displacements, aggravate localized subsidence, and discontinue the integrity of ground water flow. Property damages due to fault creep have become more evident during the past few years over the GH area, portraying the necessity of further study of these faults. Interferometric synthetic aperture radar (InSAR) has been proven to be effective in mapping creep along and/or across faults. However, extracting a short wavelength, as well as small amplitude of the creep signal (about 10-20 mm/year) from long time span interferograms is extremely difficult, especially in agricultural or vegetated areas. This paper aims to map and monitor the latest rate, extent, and temporal evolution of faulting at a highest spatial density over GH region using an improved Multi-temporal InSAR (MTI) technique. The method, with maximized usable signal and correlation, has the ability to identify and monitor the active faults to provide an accurate and elaborate image of the faults. In this study, two neighboring ALOS tracks and Sentinel-1A datasets are used. Many zones of steep phase gradients and/or discontinuities have been recognized from the long term velocity maps by both ALOS (2007-2011) and Sentinei-1A (2015-2017) imagery. Not only those previously known faults position but also the new fault traces that have not been mapped by other techniques are imaged by our MTI technique. Fault damage and visible cracking of ground were evident at most locations through our field survey. The discovery of new fault activation, or faults moved from earlier locations is a part of the Big Barn Fault and Conroe fault system, trending from southwest to northeast between Hockley and Conroe. The location of area of subsidence over GH is also shrinking and migrating toward the northeast (Montgomery County) after 2000. The

    What diagnoses underlie delayed puberty (DP) and predict its outcome? A multitude of different diagnoses underlie DP, and in boys a history of cryptorchidism, small testicular size and slow growth velocity (GV) predict its clinical course. DP is caused by a variety of underlying etiologies. Hormonal markers can be used in the differential diagnosis of DP but none of them have shown complete diagnostic accuracy. Medical records of 589 patients evaluated for DP in a single tertiary care center between 2004 and 2014 were retrospectively reviewed. Clinical and biochemical data of 174 boys and 70 girls who fulfilled the criteria of DP were included in the analyses. We characterized the frequencies of underlying conditions and evaluated the predictive efficacy of selected clinical and hormonal markers. Thirty etiologies that underlie DP were identified. No markers of clinical value could be identified in the girls, whereas a history of cryptorchidism in the boys was associated with an increase in the risk of permanent hypogonadism (odds ratio 17.2 (95% CI; 3.4-85.4, P hypogonadism were more frequent in boys with a GV below 3 cm/yr than in those growing faster (19% vs 4%, P hypogonadism (CHH) were testicular volume (cut-off 1.1 ml with a sensitivity of 100% and a specificity of 91%), GnRH-induced maximal LH (cut-off 4.3 IU/L; 100%, 75%) and basal inhibin B (INHB) level (cut-off 61 ng/L; 90%, 83%). The main limitation of the study is the retrospective design. Prior cryptorchidism and slow GV are two important clinical cues that may help clinicians to predict the clinical course of DP in boys, whereas markers of similar value could not be identified in girls. In prepubertal boys, testicular size appeared as effective as INHB and GnRH-induced LH levels in the differential diagnosis between CHH and CDGP.

    Control, the final function of the four-step management approach discussed in this series of columns, is aimed at establishing standards of performance, measuring current performance under those standards, and taking action needed to ensure that organizational objectives are met. It follows planning, organizing, and directing. Often a manager plans wisely, organizes key department processes efficiently, and directs employee activities effectively--but neglects to set standards and controls for successfully completing the department's plans. Setting standards, measuring employee performance, and implementing corrective action are the key processes of controlling.

    Full Text Available La enfermedad de Chagas es un padecimiento que predomina en aquellas regiones del continente americano que combinan condiciones geográficas, climáticas y ecológicas para que el hombre, el Trypanosoma cruzi, sus reservorios y vectores, interactúen de manera ideal. Objetivo: presentar nueve casos de enfermedad de Chagas diagnosticados mediante autopsia en el Departamento de Patología de la Universidad Industrial de Santander entre 2002 y 2009, correlacionar los hallazgos pos-mortem con las manifestaciones clínicas y comparar los datos obtenidos con la información referida en la literatura mundial. Materiales y Métodos: estudio descriptivo, retrospectivo en casos de autopsias realizadas en el Departamento de Patología de la Universidad Industrial de Santander entre el primero de enero de 2002 y el 30 de junio de 2009. Resultados: de un total de 756 autopsias, nueve (1,2% correspondieron a pacientes con diagnóstico confirmado de enfermedad de Chagas: siete hombres y dos mujeres. El rango de edad osciló entre 14 meses y 56 años. De los casos analizados cinco correspondieron a la forma aguda, dos a la forma crónica y dos a un proceso de reactivación. Todos tenían compromiso cardíaco, uno compromiso del colon y uno compromiso encefálico. La causa de muerte se relacionó de manera directa con estas afecciones. Conclusión: en zonas endémicas, ante la presencia de manifestaciones cardíacas, es necesario considerar la enfermedad de Chagas con el fin de realizar un diagnóstico precoz y oportuno que permita identificar casos y establecer medidas de manejo específico enfocado de acuerdo con su condición.Chagas disease is a condition that prevails in those regions of the Americas that combine geographical, climatic and ecological conditions so that man,Trypanosoma cruzi, their reservoirs and vectors may ideally interact.

    Emergency departments use has been constantly increasing over the world. Overcrowding is defined as a situation which compromises patient safety because of delayed cares. This situation is often reached. Emergency departments have to continuously improve their organization to be able to ensure the same quality of care to a higher number of patients. Thus a good organization is essential: it doesn't always avoid overcrowding. The rest of the hospital has to be involved in this process to ensure efficiency. We examine the various interventions and procedures that can be found in medical literature for improving patients flow and management in emergency departments.

Historically incorporated into the psychiatric hospital, emergency mental health care has since been moved to the general hospital. This move was intended to boost the accessibility and deinstitutionalisation of psychiatry. The end of the "asylum" opened up new dialogue with the somatic care network.

    2000-01-01

    Full text: During last year the physicists of the Department of Nuclear Reactions were involved in many experiments and projects: -Low energy nuclear reactions: For the first time a heavy ion beam from the Warsaw Cyclotron C-200 was used to investigate elastic and inelastic scattering of 12 C ions from 12 C target. The experiment is a part of a long range programme devoted to study the energy dependence of the nucleus-nucleus interactions. -Multifragmentation of relativistic heavy ions: Multifragmentation reactions induced by 12 C on different heavy targets and at different energies were studied in experiments performed at Gesellschaft fuer Schwerionenforschung by the ALADIN Collaboration. These asymmetric systems were investigated in order to study the interplay between preequilibrium and equilibrium phenomena in the nuclear liquid - gas phase transition. -The structure of nucleons: A novel, two-structure description of the Roper resonance was proposed on the basis of the α-p scattering data reanalysed by means of a T-matrix formalism. -Atomic physics: Emission of the X-rays by fast heavy ions (S, Ti, Fe) as they traverse the matter (thin carbon or other light element foil) was investigated in a series of experiments performed at University of Erlangen. It was demonstrated, that the characteristic K α X-rays emitted by a heavy ion can serve as a tool for Z-value control of the ion. -Material research: Semiconductor heterostructures were investigated by means of Rutherford Back Scattering and Channeling methods using the 2 MeV α particles from the Van de Graaff accelerator ''Lech'' at the Department. The following reports present the results and major successes which were achieved in 1999. (author)

  15. Managing emergency department overcrowding.

    Science.gov (United States)

    Olshaker, Jonathan S

    2009-11-01

    Emergency department (ED) crowding and ambulance diversion has been an increasingly significant national problem for more than a decade. More than 90% of hospital ED directors reported overcrowding as a problem resulting in patients in hallways, full occupancy of ED beds, and long waits, occurring several times a week. Overcrowding has many other potential detrimental effects including diversion of ambulances, frustration for patients and ED personnel, lesser patient satisfaction, and most importantly, greater risk for poor outcomes. This article gives a basic blueprint for successfully making hospital-wide changes using principles of operational management. It briefly covers the causes, significance, and dangers of overcrowding, and then focuses primarily on specific solutions.

    We introduce a platform which supplies an easy-to-handle, interactive, extendable, and fast analysis tool for time series analysis. In contrast to other software suits like Maple, Matlab, or R, which use a command-line-like interface and where the user has to memorize/look-up the appropriate...... commands, our application is select-and-click-driven. It allows to derive many different sequences of deviations for a given time series and to visualize them in different ways in order to judge their expressive power and to reuse the procedure found. For many transformations or model-ts, the user may...... choose between manual and automated parameter selection. The user can dene new transformations and add them to the system. The application contains efficient implementations of advanced and recent techniques for time series analysis including techniques related to extreme value analysis and filtering...

    We present a forecasting technique for chaotic data. After embedding a time series in a state space using delay coordinates, we ''learn'' the induced nonlinear mapping using local approximation. This allows us to make short-term predictions of the future behavior of a time series, using information based only on past values. We present an error estimate for this technique, and demonstrate its effectiveness by applying it to several examples, including data from the Mackey-Glass delay differential equation, Rayleigh-Benard convection, and Taylor-Couette flow

    Previously synthesized only as powders, single crystals of the RE2Ru3Ge5 (RE = La, Ce, Nd, Gd, Tb) series of compounds have been now been obtained from molten In. These materials crystallize with the U2Co3Si5-type structure in orthorhombic space group Ibam with lattice parameters a ~ 10.00-9.77 Å (La-Tb), b ~ 12.51-12.35 Å, and c ~ 5.92-5.72 Å. The structure is a three-dimensional framework consisting of RuGe5 and RuGe6 units, as well as Ge-Ge zigzag chains. This structure type, along with the other five (Sc2Fe3Si5, Lu2Co3Si5, Y2Rh3Sn5, Yb2Ir3Ge5, and Yb2Pt3Sn5) to compose the RE2T3X5 phase space, are discussed in depth. For the three compounds with RE = Nd, Gd, and Tb, multiple magnetic transitions and metamagnetic behavior are observed. Electronic band structure calculations performed on La2Ru3Ge5 indicate that these materials have a negative band gap and are semimetallic in nature.

  16. Trivariate causality between economic growth, urbanisation and electricity consumption in Angola: Cointegration and causality analysis

    International Nuclear Information System (INIS)

    Solarin, Sakiru Adebola; Shahbaz, Muhammad

    2013-01-01

    This paper investigates the causal relationship between economic growth, urbanisation and electricity consumption in the case of Angola, while utilizing the data over the period of 1971–2009. We have applied Lee and Strazicich (2003. The Review of Economics and Statistics 63, 1082–1089; 2004. Working Paper. Department of Economics, Appalachian State University) unit root tests to examine the stationarity properties of the series. Using the Gregory–Hansen structural break cointegration procedure as a complement, we employ the ARDL bounds test to investigate long run relationships. The VECM Granger causality test is subsequently used to examine the direction of causality between economic growth, urbanisation, and electricity consumption. Our results indicate the existence of long run relationships. We further observe evidence in favour of bidirectional causality between electricity consumption and economic growth. The feedback hypothesis is also found between urbanisation and economic growth. Urbanisation and electricity consumption Granger cause each other. We conclude that Angola is energy-dependent country. Consequently, the relevant authorities should boost electricity production as one of the means of achieving sustainable economic development in the long run. - Highlights: • We consider the link between electricity consumption and economic growth in Angola. • Urbanisation is added to turn the research into a trivariate investigation. • Various time series procedures are used. • Results show that increasing electricity will improve economic growth in Angola. • Results show urbanisations reduced economic growth during civil war

    Full text: The Department's continuing interest is centered on the mechanisms of mutagenesis and DNA repair. Part of the studies concerns the effects of the interdependence of mutator and antimutator genes on the response of E. coli cells to various mutagens. The phenomenon of mutation frequency decline (MFD) was studied and recently distinct response of this system to UV light and to alkylating agents was shown. Studies on the isfA gene, which is involved in the regulation of the SOS response, including its precise localization on the bacterial chromosome, were continued. Also, studies on the mechanism of DNA replication-independent mutagenesis in lambda phage were continued. Halogen light mutagenesis and the role of the hem gene in the near UV and UVA irradiation mutagenesis were investigated. New experimental approaches were adapted to study adaptive mutations. Another part of the studies was focused on the relation between the structure of DNA bases adducts and their coding and mutagenic properties, as well as their properties as substrates for DNA repair enzymes. These studies include instrumental methods, such as NMR, MS, HPLC and GC/MS, to investigate structure and the kinetics of formation and excision of adducts, and organic chemistry methods to synthesize adducts. The coding and mutagenic properties of several oxidized and alkylated bases (including imidazole-ring opened purines) were determined by employing in vitro enzymatic and phage/bacteria systems. The sites of reaction of chloroacetaldehyde, a metabolite of carcinogenic vinyl chloride, with a fragment of human p53 gene, were studied using the method of polymerase fingerprint analysis. Ethenoadducts, the products of the reaction of chloroacetaldehyde with adenine and cytosine, and also products of solvolytic degradation of ethenoadenine, were studied as substrates of various DNA glycosylases. Several purine and pyrimidine derivatives were synthesized and tested as inhibitors of DNA glycosylases

    Full text: The activities of Department was engaged in the selected topics in nuclear fission reactor science and engineering. Present and future industry competitiveness, economic prosperity and living standards within the world are strongly dependent on maintaining the availability of energy at reasonable prices and with security of supply. Also, protection of man and the environment from the harmful effects of all uses of energy is an important element of the quality of life especially in Europe. It is unrealistic to assume that the technology for renewable (hydro, wind, solar and biomass) available within a 20-30 year perspective could provide the production capacity to replace present use of nuclear power and at the same time substantially reduce the use of fossil fuels, especially when considering that energy demand in industrialized countries can be expected to continue to increase even within a framework of overall energy conservation and continued improvement of efficiency in energy usage. In the area of nuclear fission, we continue support to maintain and develop the competence needed to ensure the safety of existing and future reactors and other nuclear installations. In addition support is given to explore the potential for improving present fission technology from a sustainable development point of view.

    This text for advanced undergraduate and graduate students introduces Hilbert space and analytic function theory, which is centered around the invariant subspace concept. The book's principal feature is the extensive use of formal power series methods to obtain and sometimes reformulate results of analytic function theory. The presentation is elementary in that it requires little previous knowledge of analysis, but it is designed to lead students to an advanced level of performance. This is achieved chiefly through the use of problems, many of which were proposed by former students. The book's

Particularly important are the results on the quark transverse spin polarisation in the nucleon. The Hermes experiments have found evidence of nonvanishing quark transverse polarisation and have provided an indication for a nonzero orbital angular momentum of quarks in the nucleon. - Atomic physics - The L-shell ionisation cross sections for atoms of some heavy elements were measured. The results are presented and compared to different model calculations. - Materials research - Our group of scientists performed many experimental studies using low-energy p-, d- and α- beams from the van de Graaff accelerator of the Department which were commissioned by other institutions. In this Annual Report the results of experiments devoted to studying damage buildup and recovery of compound semiconductors are presented. The experiments were performed at the Friedrich Schiller University of Jena, in collaboration with local scientists. Our involvement in education and science popularization has become a tradition. Students of Warsaw High Schools and of Warsaw University attended in 2004 many lectures given by Dr. Andrzej Korman and Dr. Lech Nowicki on nuclear physics, accelerators, detectors and nuclear methods in solid state physics. Our contribution to the 8 th Scientific Picnic and the 11 th Science Festival is also worth mentioning. (author)

    Vazquez, Jorge A.

    2014-01-01

    Application of U-series dating to volcanic rocks provides unique and valuable information about the absolute timing of crystallization and differentiation of magmas prior to eruption. The 238U–230Th and 230Th-226Ra methods are the most commonly employed for dating the crystallization of mafic to silicic magmas that erupt at volcanoes. Dates derived from the U–Th and Ra–Th methods reflect crystallization because diffusion of these elements at magmatic temperatures is sluggish (Cherniak 2010) and diffusive re-equilibration is insignificant over the timescales (less than or equal to 10^5 years) typically associated with pre-eruptive storage of nearly all magma compositions (Cooper and Reid 2008). Other dating methods based on elements that diffuse rapidly at magmatic temperatures, such as the 40Ar/39Ar and (U–Th)/He methods, yield dates for the cooling of magma at the time of eruption. Disequilibrium of some short-lived daughters of the uranium series such as 210Po may be fractionated by saturation of a volatile phase and can be employed to date magmatic gas loss that is synchronous with volcanic eruption (e.g., Rubin et al. 1994).

    Since 2004, faculty members at Caldwell University have developed three successful graduate programs in Applied Behavior Analysis (i.e., PhD, MA, non-degree programs), increased program faculty from two to six members, developed and operated an on-campus autism center, and begun a stand-alone Applied Behavior Analysis Department. This paper outlines a number of strategies used to advance these initiatives, including those associated with an extensive public relations campaign. We also outline challenges that have limited our programs' growth. These strategies, along with a consideration of potential challenges, might prove useful in guiding academicians who are interested in starting their own programs in behavior analysis.

    Many nonlinear optical (NLO) crystals have been identified as potential candidates in optical and electro-optical devices. Use of NLO organic crystals is expected in photonic applications. Hence organic nonlinear optical materials have been intensely investigated due to their potentially high nonlinearities, and rapid response in electro-optic effect compared to inorganic NLO materials. There are many methods to grow organic crystals such as vapor growth method, melt growth method and solution growth method. Out of these methods, solution growth method is useful in providing constraint free crystal. Single crystals of Dopamine have been grown by evaporating the solvents from aqueous solution. Crystals obtained were of the size of orders of mm. The crystal structure of dopamine was determined using XRD technique. Images of crystals were obtained using FEG SEM Quanta Series under high vacuum and low KV.

    Full text: Our activity in 2008 has focused on well-established domains of research: nuclear and atomic physics, and applications. · As far as nuclear physics is concerned; our interests are very broad, ranging from the structure of the nucleon to the structure of the nucleus including high-energy multifragmentation studies. Our colleagues led by Prof. Pawel Zupranski, members of the HERMES collaboration that comprises 32 institutions from eleven countries at the Deutsches Elektronen Synchrotron (DESY) in Hamburg, worked last year on the extraction of Spin Density Matrix Elements of vector mesons from scattering experiments on hydrogen targets. They also studied the distribution of quarks and gluons in nucleon. A team led by Prof. B. Zwieglinski was involved in the large-scale international collaboration PANDA (antiProton ANnihilation at DArmstadt). They studied the response of cooled PWO scintillators irradiated by gammas in the energy range of 4-20 MeV. The gammas were produced radiative proton capture on light by nuclei using a proton beam from the Van de Graaff accelerator of our Department. As a result, an important extrapolation of measurements performed by another group of physicists at much higher γ-ray energies was obtained. Low energy nuclear physics experiments were continued at the Heavy Ion Laboratory of Warsaw University in collaboration with foreign institutions: the University of Jyvaeskylae, the Institute of Nuclear Research of the Ukrainian Academy of Science and the Institute de Recherches Subatomique in Strasbourg. At high energies, a study of the isospin - dependence of the caloric curve was performed by the ALADIN Collaboration in a series of experiments at GSI - Darmstadt using radioactive beams of Sn and La. It was found that the asymmetry due to isospin is very weak. · Atomic physics studies were devoted to ionisation of heavy atoms by oxygen ions from the tandem accelerator of Erlangen-Nuernberg University.

  6. Modelling bursty time series

    International Nuclear Information System (INIS)

    2013-01-01

    Many human-related activities show power-law decaying interevent time distribution with exponents usually varying between 1 and 2. We study a simple task-queuing model, which produces bursty time series due to the non-trivial dynamics of the task list. The model is characterized by a priority distribution as an input parameter, which describes the choice procedure from the list. We give exact results on the asymptotic behaviour of the model and we show that the interevent time distribution is power-law decaying for any kind of input distributions that remain normalizable in the infinite list limit, with exponents tunable between 1 and 2. The model satisfies a scaling law between the exponents of interevent time distribution (β) and autocorrelation function (α): α + β = 2. This law is general for renewal processes with power-law decaying interevent time distribution. We conclude that slowly decaying autocorrelation function indicates long-range dependence only if the scaling law is violated. (paper)

  7. Predictability of geomagnetic series

    Directory of Open Access Journals (Sweden)

    E. Bellanger

    Full Text Available The aim of this paper is to lead a practical, rational and rigorous approach concerning what can be done, based on the knowledge of magnetic series, in the field of prediction of the extreme geomagnetic events. We compare the magnetic vector differential at different locations computed with different resolutions, from an entire day to minutes. We study the classical correlations and the simplest possible prediction scheme to conclude a high level of predictability of the magnetic vector variation. The results obtained are far from a random guessing: the error diagrams are either comparable with earthquake prediction studies or out-perform them when the minute sampling is used in accounting for hourly magnetic vector variation. We demonstrate how the magnetic extreme events can be predicted from the hourly value of the magnetic variation with a lead time of several hours. We compute the 2-D empirical distribution of consecutive values of the magnetic vector variation for the estimation of conditional probabilities of different types. The achieved results encourage further development of the approach to prediction of the extreme geomagnetic events.

    1993-01-01

    I welcome this opportunity to present my fourth annual report on the posture of the United States Department of Energy (DOE). This report will provide a retrospective on the Department I inherited four years ago, the progress made during this period, and thoughts on future directions and challenges facing the new Administration. Since my confirmation on March 1, 1989, it has been an honor to serve President Bush and the Nation as the sixth Secretary of Energy. I have held this office during a period of breathtaking change in the world. Who would have imagined four years ago the end of the cold war, the collapse of the Soviet Union, and the crumbling of the Berlin Wall, all of which have brought hope of a ``new world order`` of stability, growth, and cooperation among nations. Yet, these four years also have seen this new hope threatened by regional conflict. The Iraqi invasion of Kuwait served as a stark reminder both of the dangers that remain in the world and of the energy vulnerabilities we face as a Nation. These changes have had a profound effect on the missions and priorities of the Department of Energy. Over the past four years, we have made significant progress in addressing these challenges. While there is still much to be done, the next Secretary of Energy will find that DOE is now positioned to address the remaining challenges and opportunities as our Nation moves into the next century.

    Full text: The Department of Training and Consulting concentrates on the dissemination of knowledge on radiation phenomena: the origins, applications and health effects of ionizing radiation in particular. Its activity is open to the public. However, the main recipients are students of secondary schools and teachers. During about 12 years of such activity the number of visitors has exceeded 60 000 persons, while during last few years the average number of our visitors varies between 6 000 and 7 000 per year, which shows how much this kind of activity is needed. It should be noted that the term 'visitor' is not the most appropriate, because what the 'visitor' actually experiences in the Department is a series of lectures with demonstrations, visits to the MARIA reactor or regular experimenting in a specially designed Laboratory of Atomic and Nuclear Physics for schools, teachers and university students. The Department organized two permanent exhibitions. One is connected with the nuclear waste treatment and storage, another one displays a large model. 4x4x4 m. of a nuclear reactor of the WWER-type which was about to be installed at Zarnowiec about 20 years ago. The Department is equally active during annual Picnics and Festivals of Science in Warsaw and other Polish towns. Our staff is often asked to deliver lectures outside the Institute for Nuclear Studies, and participates in discussions on problems of teaching, in addition, the Department leads, together with the Institute of Physics of the Polish Academy of Sciences, Warsaw, the annual competition, named '' Physical Paths '', for high-school students. The competition is arranged in three categories: research, demonstration of physical phenomena, and essays on physics and its relation to civilization. This competition particularly stimulates small educational centers in Poland. This year, 2010, the competition was organized for the fifth time.

  11. Departments as Agents of Change

    Science.gov (United States)

    Lagowski, J. J.

    1996-07-01

    Higher education is changing because it has no choice. And, for the most part, outside influences are dictating the processes of change. The more fortunate institutions have had a flat budget during this period, but most have been forced to deal with a declining revenue stream as well. Legislators seem bent on micromanaging state-supported institutions, even as they cut their support. Regulators demand greater institutional accountability. Students and their parents expect more service at lower prices and increased flexibility. Technological advances have dramatically affected the availability and accessibility of extant knowledge. It is no longer a question of whether institutions will change, but rather, who will control the change. Most institutions possess long-standing academic traditions, but these are placed at risk in an increasingly competitive market that holds little sympathy for such traditions and may even see them as obstacles or barriers. As a result, the change agents will undoubtedly have a profound effect on the very nature of academic institutions. From the academic point of view, it would seem prudent to attempt to manage the changes that will inevitably occur. A number of concerned observers, notably the Pew Higher Education Roundtable and the American Association for Higher Education, argue persuasively that the academic department is the logical focus for responding to the current winds of change. Using a marketing metaphor, the academic department has been likened to a "producers' cooperative" of services that consumers seek. Thus, the department should be held accountable for the quality of teaching delivered by its members, for the coherence of its major, for its contributions to the general education curriculum, and for supervising and rewarding its individual faculty members. If departments are to be held accountable, it is surely in their best interest to act in such a way that they are accountable. Expecting academic departments to be

    competing ferro- and antiferromagnetic interactions give rise to phase transitions which have been studied by means of static and dynamic magnetometry. For two series Gd T Mg (T= Ag, Au, Pd and Pt) and R Pd In (R = Gd, Tb, Dy, Ho, and Er) the temperatures and the types of phase transitions have been determined. Solid solutions of orthoferrites and orthogallates have been investigated wthin a joint project with the Academy of Mining and Metallurgy. Substitution of the Fe +3 ions in the distorted perovskite structure by the nonmagnetic ions of Al +3 and Ga +3 results in substantial shift of the compensation point and of the spontaneous spin reorientation region. A new subject in our studies is a search for molecular and polymeric systems (organic and organometallic) showing cooperative magnetic phenomena. Among the different compounds (synthesized in the Institute of Chemistry of the Jagiellonian University) the most interesting one is Cu 4 (H 2 O) 4 [W(CN) 8 ] 4 . The compound has been found to be a soft ferromagnet with T c = 34 K. Our Department maintains a program of weekly internal seminars. The latter provide a unique discussion forum for our current results as well as those presented by invited speakers. Much of our activity would not be possible without the financial support from the Polish Committee for Scientific Research. (author)

  12. Effects of acute alcohol intoxication on growth axis in human adolescents of both sexes.

    Science.gov (United States)

    Frias, J; Torres, J M; Rodriguez, R; Ruiz, E; Ortega, E

    2000-10-20

    We previously reported the deleterious effects of acute alcohol intoxication (AAI) on pituitary-gonadal and pituitary-adrenal axes hormones in human adolescents. In the present paper we studied the effects of AAI on the growth axis hormones, and the possible contribution of the insulin-glucose axis to the alcohol-induced dysfunction of the growth axis in human adolescents. Blood samples were drawn from adolescents that arrived at the emergency department with evident behavioural symptoms of drunkenness (AAI) or with nil consumption of alcohol (controls [C]). AAI produced in the adolescents of both sexes in our series: a decrease in growth hormone (GH) levels, without significant alteration of either insulin-like growth factor-I (IGF-I) or insulin-like growth factor binding protein-3 (IGFBP3); an increase in plasma glucose and a decrease in insulin in the female adolescents but not in the males. Males and females undergo a significant period of bone growth during adolescence. Growth axis hormones play an important role in the pubertal spurt. Thus, ethanol consumption during adolescence could have long-lasting deleterious effects on this aspect of development. In industrialised countries, around 35% of alcohol drinkers are under 16 years old, therefore the result of this study should be made known to adolescents and the appropriate authorities.

    (full text) Work carried out in 1997 in the Department of Radiation Detectors concentrated on three subjects: (i) Semiconductor Detectors (ii) X-ray Tube Generators (iii) Material Modification using Ion and Plasma Beams. Semiconductor detectors: Semiconductor detectors of ionizing radiation are among the basic tools utilized in such fields of research and industry as nuclear physics, high energy physics, medical (oncology) radiotherapy, radiological protection, environmental monitoring, energy dispersive X-ray fluorescence non-destructive analysis of chemical composition, nuclear power industry. The Department all objectives are: - search for new types of detectors, - adapting modern technologies (especially of industrial microelectronics) to detector manufacturing, - producing unique detectors tailored for physics experiments, - manufacturing standard detectors for radiation measuring instruments, - scientific development of the staff. These 1997 objectives were accomplished particularly by: - research on unique detectors for nuclear physics (e.g. transmission type Si(Li) detectors with extremely thin entrance and exit window), - development of technology of high-resistivity (HRSi) silicon detectors and thermoelectric cooling systems (KBN grant), - study of the applicability of industrial planar technology in producing detectors, - manufacturing detectors developed in previous years, re-generating and servicing customer detectors of various origin. In accomplishing of the above, the Department cooperated with interested groups of physicists from our Institute (P-I and P-II Departments), Warsaw University, Warsaw Heavy Ion Laboratory and with some technology Institutes based in Warsaw (ITME, ITE). Some detectors and services have been delivered to customers on a commercial basis.

  15. Benchmarking of energy time series

    Energy Technology Data Exchange (ETDEWEB)

    Williamson, M.A.

    1990-04-01

    Benchmarking consists of the adjustment of time series data from one source in order to achieve agreement with similar data from a second source. The data from the latter source are referred to as the benchmark(s), and often differ in that they are observed at a lower frequency, represent a higher level of temporal aggregation, and/or are considered to be of greater accuracy. This report provides an extensive survey of benchmarking procedures which have appeared in the statistical literature, and reviews specific benchmarking procedures currently used by the Energy Information Administration (EIA). The literature survey includes a technical summary of the major benchmarking methods and their statistical properties. Factors influencing the choice and application of particular techniques are described and the impact of benchmark accuracy is discussed. EIA applications and procedures are reviewed and evaluated for residential natural gas deliveries series and coal production series. It is found that the current method of adjusting the natural gas series is consistent with the behavior of the series and the methods used in obtaining the initial data. As a result, no change is recommended. For the coal production series, a staged approach based on a first differencing technique is recommended over the current procedure. A comparison of the adjustments produced by the two methods is made for the 1987 Indiana coal production series. 32 refs., 5 figs., 1 tab.

  7. Time series with tailored nonlinearities

    Science.gov (United States)

    Räth, C.; Laut, I.

    2015-10-01

    It is demonstrated how to generate time series with tailored nonlinearities by inducing well-defined constraints on the Fourier phases. Correlations between the phase information of adjacent phases and (static and dynamic) measures of nonlinearities are established and their origin is explained. By applying a set of simple constraints on the phases of an originally linear and uncorrelated Gaussian time series, the observed scaling behavior of the intensity distribution of empirical time series can be reproduced. The power law character of the intensity distributions being typical for, e.g., turbulence and financial data can thus be explained in terms of phase correlations.

    Fairly early in the development of the theory of summability of divergent series, the concept of convergence factors was recognized as of fundamental importance in the subject. One of the pioneers in this field was C. N. Moore, the author of the book under review.... Moore classifies convergence factors into two types. In type I he places the factors which have only the property that they preserve convergence for a convergent series or produce convergence for a summable series. In type II he places the factors which not only maintain or produce convergence but have the additional property that

    The technology of modifying surfaces of practical-use materials by means of continuous and pulsed energy and particle beams has been intensely studied for more than 20 years. In some fields it is presently utilized on a wide scale in industry. Continuous or pulsed ion and plasma beams play a significant role among various approaches used in this area. The research carried by Department P-IX is centered around the use of two own ion implantation machines (ion implanters) of different kind and several world-wide unique sources of high-intensity intense plasma pulses, utilized jointly with Department P-V. The Department cooperates closely with Forschungszentrum Rossendorf (FZR, Dresden, Germany) in the field of ion-beam-based analytical techniques and the use of unique ion implantation facilities. The main objectives of the Department are: search for new ways of modifying surface properties of solid materials by means of continuous or pulsed ion and plasma beams and implementation of ion implantation technique in national industries as a method of improving the lifetime of machine parts and tools utilized in industry. In 2006 these objectives were accomplished in many ways, particularly by research on: formation of superconducting MgB 2 phases, electrical conductivity in metallic nano-layers produced in oxide insulators (Al 2 O 3 ) by ion implantation, ion implantation as a method of improving mechanical properties of stainless steels without degrading their corrosion resistance, ion implantation/plasma treatment of ceramics aimed at improving their wettability in ceramic-metal joints, methods of controlling wear of ceramic-polymer pairs used in bio-medical applications.

    The Panel recommends the following major roles and missions for the laboratories: perform the Department's national trust fundamental research missions in the physical sciences, including high energy and nuclear physics, and the radiobiological sciences including nuclear medicine; sustain scientific staff core capabilities and specialized research facilities for laboratory research purposes and for use by other Federal agencies and the private sector; perform independent scientific and technical assessment or verification studies required by the Department; and perform generic research and development where it is judged to be in the public interest or where for economic or technical reasons industry does not choose to support it. Organizational efficiencies if implemented by the Department could contribute toward optimal performance of the laboratories. The Panel recommends that a high level official, such as a Deputy Under Secretary, be appointed to serve as Chief Laboratory Executive with authority to help determine and defend the research and development budget, to allocate resources, to decide where work is to be done, and to assess periodically laboratory performance. Laboratory directors should be given substantially more flexibility to deploy resources and to initiate or adapt programs within broad guidelines provided by the Department. The panel recommends the following actions to increase the usefulness of the laboratories and to promote technology transfer to the private sector: establish user groups for all major mission programs and facilities to ensure greater relevance for Department and laboratory efforts; allow the laboratories to do more reimbursable work for others (other Federal agencies, state and local governments, and industry) by relaxing constraints on such work; implement vigorously the recently liberalized patent policy; permit and encourage joint ventures with industry

    Full text: The principal Department's duties in 1999 have not changed and were consequently directed on development in the area of electron and ion accelerators and their applications in science, medicine and technology. Two important events dominated the current and future orientation of R and D activity. The first was finalizing of long time efforts for preparing of the ordered research project granted by the State Committee of Scientific Research and devoted to elaboration and design of a new electron accelerator for radiotherapy, with two energies of X-ray photon beams. This project was formally approved in March 1999 and due to organisatory procedures set in operation after few months. In the second half of 1999, an important progress was done in advancing the project. The second mentioned event is foundation by the government of a Multiyear Research Programme - called ''Isotopes and Accelerators''. This programme formulates a broad spectrum of important tasks oriented on application of isotopes and accelerator techniques in many branches of science and national economy. The expected participation of the Department in this programme comprises following subjects: medical interoperative accelerator, high power electron accelerator for radiation technology, and upgrading of cyclotron for isotopes production. In course of 1999, preparatory studies in these subjects were carried out. Some of the results were presented on conferences and seminars. An interesting experience was the expertise done on technical status of Eindhoven isochronous cyclotron and its possible transfer to Swierk as a professional tool for isotopes production. In the group of medical applications, three subjects were continued during 1999 and brought important results: - completion of microwave measurements of high gradient acceleration structure for low energy accelerators; such structure will be very useful solution for Co-Line and interoperative accelerator; - evaluation of design data and

    This paper addresses the topic of classifying financial time series in a fuzzy framework proposing two fuzzy clustering models both based on GARCH models. In general clustering of financial time series, due to their peculiar features, needs the definition of suitable distance measures. At this aim, the first fuzzy clustering model exploits the autoregressive representation of GARCH models and employs, in the framework of a partitioning around medoids algorithm, the classical autoregressive metric. The second fuzzy clustering model, also based on partitioning around medoids algorithm, uses the Caiado distance, a Mahalanobis-like distance, based on estimated GARCH parameters and covariances that takes into account the information about the volatility structure of time series. In order to illustrate the merits of the proposed fuzzy approaches an application to the problem of classifying 29 time series of Euro exchange rates against international currencies is presented and discussed, also comparing the fuzzy models with their crisp version.

    1997-11-01

    The Department of Energy (DOE) national laboratories have one of the longest and most consistent histories of supercomputer use. The authors summarize the architecture of DOE`s new supercomputers that are being built for the Accelerated Strategic Computing Initiative (ASCI). The authors then argue that in the near future scaled-down versions of these supercomputers with petaflop-per-weekend capabilities could become widely available to hundreds of research and engineering departments. The availability of such computational resources will allow simulation of physical phenomena to become a full-fledged third branch of scientific exploration, along with theory and experimentation. They describe the ASCI and other supercomputer applications at Sandia National Laboratories, and discuss which lessons learned from Sandia`s long history of supercomputing can be applied in this new setting.

    This article has presented an overview of the duties, responsibilities, and management roles of the emergency department Medical Director, a position that can be among the most challenging, stimulating, and exciting in medicine. However, prior to accepting a position as an Emergency Department medical director, one should have a clear understanding of what the job entails. Careful discussions with the hospital administration, medical staff, nursing personnel, and staff emergency physicians should be undertaken to learn the perceptions of these people and expectations of the position. Once the job has been accepted, using the roles, responsibilities, and duties detailed herein may be of benefit--but should always be applied with good judgment, tactful cooperation, and common sense. Finally, it should not be surprising to a medical director to find, as Spinoza did many years ago, that the excellent thing he aspires to are as difficult as they are rare.

    Full text: Work carried out in 1998 in the Department of Radiation Detectors concentrated on three subjects: (i) Semiconductor Detectors (ii) X-ray Tube Generators (iii) Material Modification Using Ion and Plasma Beams. SEMICONDUCTOR DETECTORS: Semiconductor detectors of ionizing radiation are among the basic tools utilized in such fields of research and industry as nuclear physics, high energy physics, medical (oncology) radiotherapy, radiological protection, environmental monitoring, energy dispersive X-ray fluorescence non-destructive analysis of chemical composition, nuclear power industry. The departmental objectives are: a search for new types of detectors; producing unique detectors tailored for physics experiments; manufacturing standard detectors for radiation measuring instruments; scientific development of the staff. These objectives were accomplished in 1998 particularly by: research on unique thin silicon detectors for identification of particles in E-ΔE telescopes, modernization of technology of manufacturing Ge(Li) detectors capable of detecting broader range of gamma energies, manufacturing detectors developed in previous years, re-generating and servicing customer detectors of various origin. In accomplishment of the above the Department co-operated with groups of physicists from IPJ, PAN Institute of Physics (Warsaw), and with some technology Institutes based in Warsaw (ITME, ITE). Some detectors and services have been delivered to customers on a commercial basis. X-Ray TUBE GENERATORS: The Department conducts research on design and technology of manufacturing X-ray generators as well as on imaging and dosimetry of X-ray beams. Various models of special construction X-ray tubes and their power supplies are under construction. In 1998 work concentrated on: completing laboratory equipment for manufacturing X-ray tubes and their components, developing technology of manufacturing X-ray tubes and their components, completing a laboratory set-up with

    The growth of managed care has provided health benefits to millions of children while attempting to control the increase in health care costs. In adhering to these goals, MCOs are often at odds with emergency departments, and the emergency department physicians providing emergency care. The appropriateness or inappropriateness of emergency department visits can be disputed, but no criteria have been established. Even the definition of emergency is debated, although many states are adopting a prudent layperson standard. Emergency medicine physicians, primary care providers, and MCOs must cooperate to fully educate parents about the appropriate use of pediatric emergency services. Patients and MCOs should use facilities that can deliver pediatric emergency and critical care or provide appropriate transport systems to facilities that can. COBRA and EMTALA set the legal requirements to which emergency departments must comply when patients present for care. The basic caveats under COBRA require a medical screening examination for every patient and the stabilization of all patients with emergency medical conditions before inquiring about insurance or patients' ability to pay. A part of gatekeeping, MCOs often require authorization for treatment. MCOs authorize payment only. Evaluation and emergency treatment should not be withheld pending authorization. After the medical screening examination, recommended treatment should be in patients' best interests. All patients with potentially life-threatening conditions should be stabilized before transport, and all transfers must comply with the EMTALA. The transfer of unstable patients purely for economic reasons is a violation of the EMTALA. When stable, patients may be transferred to other facilities, but patients requiring specialty care should be taken to facilities best able to provide that care. Financial considerations should be superseded by medical necessity. Finally, improvements can be made in the way emergency

    Full text: 1998 was the first full calendar year of the formal existence of our Department which evolved from the Laboratory of Electronic Particle Detectors (originally called Laboratory of Filmless Detectors) founded in 1972. The department is involved in two running experiments (DELPHI at CERN and H1 at DESY) and in one experiment (BELLE at KEK) which will start data taking in 1999. In addition, three department members work for the ATLAS collaboration at CERN. Since the DELPHI experiment will soon be terminated, we are considering future enterprises. One possibility is the TESLA project at DESY (our technicians have been working for several years on the construction and testing of superconducting cavities for the project). Another possibility is the LHC-b experiment at CERN. The main results of work done in 1998 are covered in reports on research. Here we mention only a few highlights. In the DELPHI experiment the cross section for the process e + e - → W + W - has been measured for several energies. Data registered so far allowed determination of the W mass with the accuracy comparable to the Tevatron results. An important role in these measurements has been played by the sophisticated silicon detector to which the Cracow group brought a substantial contribution. The analysis of more H1 data has weakened the indication for an excess of very high Q 2 events reported in 1997. Thus the paper on isolated leptons with very high transverse momenta was formulated even more carefully. In these and in several other studies the topological second level trigger designed, installed and improved by the Cracow-Orsay collaboration was very important. In the BELLE experiment the HALNY system has been designed and installed by our people. The system allows fast readout and filtering of signals from the Silicon Vertex Detector which is crucial for the experiment. One should also mention high-quality carbon-carbon composites produced in collaboration with the High Energy

    Full text: Our Department evolved from the Laboratory of Electronic Particle Detectors (originally called the Laboratory of Filmless Detectors) founded in 1972. The department is involved in three running experiments (DELPHI at CERN, H1 at DESY and BELLE at KEK). In 1999, we joined the LHC-b experiment at CERN. In addition, three department members work part-time for the ATLAS collaboration at CERN and our technicians have been working for several years on the construction and testing of superconducting cavities for the TESLA project. This arrangement provides a neat equilibrium between data producing experiments (2000 is the last year of the DELPHI running) and future projects. The main results of work done in 1999 are covered in reports on research. Here we mention only a few highlights. The first runs of the BELLE experiment have shown that the apparatus and the software can cope with the luminosity of 6 x 10 31 cm -2 s -1 presently available at KEK-B. The DELPHI experiment measured the parameters of the W boson with an accuracy comparable to that of the Tevatron. This allowed still more precise tests of the Standard Model. Some of them, like the determination of the cross sections for the production of Z 0 Z 0 and q(anti)q pairs, were actually done in Cracow. A novel study of p-p and Λ-Λ correlations performed in Cracow showed that the size of the particle emitting region decreases with particle mass. The H1 experiment published the first results on open beauty production at HERA. The cross section seems to be higher than the predictions of Quantum Chromodynamics in the Next-to-Leading Order. The work on a prototype detector for the LHC-b has just started in Cracow. One should also mention high-quality carbon-carbon composites designed and produced in collaboration with the High Energy Physics Detector Construction Group. For the first time, there were as many as 47 papers (fulfilling the highest KBN standard) published in a single year, the members of our

    Full text: 1998 was the year when, after one year of preparation, the Department started its educational activity.On October 23-rd , a permanent exhibition ''Nuclear wastes: problems, solutions'' was opened at the Centre of Education and Information (bldg. 67) of the Soltan Institute for Nuclear Studies at Swierk. The exhibition is divided into two parts: first, some introductory information about nuclear radiation displayed, next the problem of nuclear wastes and procedures used for processing, transporting and storing them shown in a series of photographs, drawings, models and descriptions. The exhibition soon became a place of interest to numerous primary and secondary schools even from such distant places from Swierk as Gliwice, students of various universities and the Institute's visitors. At the moment, our Department offers, additionally to the exhibition, introductory lectures to nuclear physics, sightseeing to the reactor MARIA in the neighboring Institute of Atomic Energy and to the experimental laboratories of SINS. We also wrote and are able to supply four educational texts on radioactive materials and their use, on ionising radiation and on nuclear waste. Another part of our educational activities was concerned with the medical technicians involved in nuclear medicine. The Department prepared two lectures (also in written form for the distribution) on nuclear radiation (mainly X-ray and γ) and its interaction with matter, as well as on the basic principles of the radiological protection in nuclear medicine. Other ''hands-on'' experiments, dedicated to this professional group, are under preparation. Last but not least, a group of 60 students from the University of Warsaw (Interfaculty Study of Environmental Protection) asked for appropriate training in ecoradiology. Such a training, on an introductory level, was prepared and conducted successfully. It seems that this group of problems will become a permanent position in our teaching activities

    CERN Document Server

    Doukhan, Paul

    2018-01-01

    This book presents essential tools for modelling non-linear time series. The first part of the book describes the main standard tools of probability and statistics that directly apply to the time series context to obtain a wide range of modelling possibilities. Functional estimation and bootstrap are discussed, and stationarity is reviewed. The second part describes a number of tools from Gaussian chaos and proposes a tour of linear time series models. It goes on to address nonlinearity from polynomial or chaotic models for which explicit expansions are available, then turns to Markov and non-Markov linear models and discusses Bernoulli shifts time series models. Finally, the volume focuses on the limit theory, starting with the ergodic theorem, which is seen as the first step for statistics of time series. It defines the distributional range to obtain generic tools for limit theory under long or short-range dependences (LRD/SRD) and explains examples of LRD behaviours. More general techniques (central limit ...

  12. Rational and Recognisable Power Series

    Science.gov (United States)

    Sakarovitch, Jacques

    This chapter presents the theory of weighted automata over graded monoids and with weights taken in arbitrary semirings. The first benefit of broadening the scope beyond free monoids is that it makes clearer the distinction between the rational and the recognisable series. As the topological machinery is set anyway, the star of series is defined in a slightly more general setting than cycle-free series. The main subjects covered in the chapter are then: the notion of covering of automata (also called bisimulation by some authors) and its relationship with the conjugacy of automata; the closure of recognisable series by Hadamard and shuffle products; the derivation of weighted rational expressions over a free monoid; the reduction theory of series over a free monoid and with weights in a (skew) field, that leads to a procedure for the decidability of equivalence (with a cubic complexity); and the basics for a theory of weighted rational relations. As a result, this chapter, among other things, lays the bases for the proof of the decidability of the equivalence of deterministic k-tape transducers which is one of the most striking examples of the application of algebra to ‘machine theory’.

  13. Uranium series disequilibrium: Concepts and applications

    International Nuclear Information System (INIS)

    Ivanovich, M.

    1994-01-01

    During the past four decades it has been recognized that natural disruption of the U and Th decay chains, resulting in the separation of parent and daughter nuclides, occurs as a consequence of geochemical processes acting in the near-surface environment. This realization has lead to a rapid growth in the application of the naturally occurring radioactive disequilibria diversifying broadly to touch upon a wide spectrum of problems in earth sciences. This paper is a brief review of the subject and addresses a number of issues concerning (1) physico-chemical processes responsible for fractionation of radionuclides in the decay series, (2) the range of observed radioactive disequilibrium in nature, (3) implications in terms of relative mobilities of U, Th, Ra and their daughters in the geosphere, and (4) examples of the application of these concepts to studies of paleoclimate, dating of old groundwaters, and rock/water interaction processes. This review concludes that the concept of radioactive disequilibrium in naturally occurring decay series is a powerful isotopic tool with applications in both terrestrial and marine environments over timescales of up to one million years.

Previous empirical studies, based on international data, have been inconclusive, in terms of the extent of the contribution of human capital to growth. We extend the Solow (1956) growth model by using educational attainment as a measure of human capital, as developed by Barro and Lee (2010). The extended Solow (1956) model performs well after allowing for the presence of structu...

The Departamental objectives are: a search for new types of detectors, adapting modern technologies (especially of industrial microelectronics) to detector manufacturing, producing unique detectors tailored for physics experiments, manufacturing standard detectors for radiation measuring instruments. These objectives were accomplished in 1996 by: research on unique detectors for nuclear physics (e.g. a spherical set of particle detectors silicon ball), detectors for particle identification), development of technology of high-resistivity silicon detectors HRSi (grant proposal), development of thermoelectric cooling systems (grant proposal), research on p-i-n photodiode-based personal dosimeters, study of applicability of industrial planar technology in producing detectors, manufacturing detectors developed in previous years, re-generating and servicing customer detectors of various origin. The Department conducts research on the design and technology involved in producing X-ray generators based on X-ray tubes of special construction. Various tube models and their power supplies were developed. Some work has also been devoted to the detection and dosimetry of X-rays. X-ray tube generators are applied to non-destructive testing and are components of analytical systems such as: X-ray fluorescence chemical composition analysis, gauges of layer thickness and composition stress measurements, on-line control of processes, others where an X-ray tube may replace a radio-isotope source. In 1996, the Department: reviewed the domestic demand for X-ray generators, developed an X-ray generator for diagnosis of ostheroporosis of human limbs, prepared a grant proposal for the development of a new instrument for radiotherapy, the so-called needle-like X-ray tube.

    2016-12-01

    Violence is common in the emergency department (ED). The ED setting has numerous environmental risk factors for violence, including poor staffing, lack of privacy, overcrowding, and ready availability of nonsecured equipment that can be used as weapons. Strategies can be taken to mitigate the risk of violence toward health care workers, including staff training, changes to the ED layout, appropriate use of security, and policy-level changes. Health care providers in the ED should be familiar with local case law and standards related to the duty to warn third parties when a violent threat is made by a patient.

  8. Diophantine approximation and Dirichlet series

    CERN Document Server

    Queffélec, Hervé

    2013-01-01

    This self-contained book will benefit beginners as well as researchers. It is devoted to Diophantine approximation, the analytic theory of Dirichlet series, and some connections between these two domains, which often occur through the Kronecker approximation theorem. Accordingly, the book is divided into seven chapters, the first three of which present tools from commutative harmonic analysis, including a sharp form of the uncertainty principle, ergodic theory and Diophantine approximation to be used in the sequel. A presentation of continued fraction expansions, including the mixing property of the Gauss map, is given. Chapters four and five present the general theory of Dirichlet series, with classes of examples connected to continued fractions, the famous Bohr point of view, and then the use of random Dirichlet series to produce non-trivial extremal examples, including sharp forms of the Bohnenblust-Hille theorem. Chapter six deals with Hardy-Dirichlet spaces, which are new and useful Banach spaces of anal...

  9. Time series modeling for syndromic surveillance

    Directory of Open Access Journals (Sweden)

    Mandl Kenneth D

    2003-01-01

    Full Text Available Abstract Background Emergency department (ED based syndromic surveillance systems identify abnormally high visit rates that may be an early signal of a bioterrorist attack. For example, an anthrax outbreak might first be detectable as an unusual increase in the number of patients reporting to the ED with respiratory symptoms. Reliably identifying these abnormal visit patterns requires a good understanding of the normal patterns of healthcare usage. Unfortunately, systematic methods for determining the expected number of (ED visits on a particular day have not yet been well established. We present here a generalized methodology for developing models of expected ED visit rates. Methods Using time-series methods, we developed robust models of ED utilization for the purpose of defining expected visit rates. The models were based on nearly a decade of historical data at a major metropolitan academic, tertiary care pediatric emergency department. The historical data were fit using trimmed-mean seasonal models, and additional models were fit with autoregressive integrated moving average (ARIMA residuals to account for recent trends in the data. The detection capabilities of the model were tested with simulated outbreaks. Results Models were built both for overall visits and for respiratory-related visits, classified according to the chief complaint recorded at the beginning of each visit. The mean absolute percentage error of the ARIMA models was 9.37% for overall visits and 27.54% for respiratory visits. A simple detection system based on the ARIMA model of overall visits was able to detect 7-day-long simulated outbreaks of 30 visits per day with 100% sensitivity and 97% specificity. Sensitivity decreased with outbreak size, dropping to 94% for outbreaks of 20 visits per day, and 57% for 10 visits per day, all while maintaining a 97% benchmark specificity. Conclusions Time series methods applied to historical ED utilization data are an important tool

    2017-12-01

    Background and aims Television series watching stepped into a new golden age with the appearance of online series. Being highly involved in series could potentially lead to negative outcomes, but the distinction between highly engaged and problematic viewers should be distinguished. As no appropriate measure is available for identifying such differences, a short and valid measure was constructed in a multistudy investigation: the Series Watching Engagement Scale (SWES). Methods In Study 1 (N Sample1  = 740 and N Sample2  = 740), exploratory structural equation modeling and confirmatory factor analysis were used to identify the most important facets of series watching engagement. In Study 2 (N = 944), measurement invariance of the SWES was investigated between males and females. In Study 3 (N = 1,520), latent profile analysis (LPA) was conducted to identify subgroups of viewers. Results Five factors of engagement were identified in Study 1 that are of major relevance: persistence, identification, social interaction, overuse, and self-development. Study 2 supported the high levels of equivalence between males and females. In Study 3, three groups of viewers (low-, medium-, and high-engagement viewers) were identified. The highly engaged at-risk group can be differentiated from the other two along key variables of watching time and personality. Discussion The present findings support the overall validity, reliability, and usefulness of the SWES and the results of the LPA showed that it might be useful to identify at-risk viewers before the development of problematic use.

    Bartke, J.

    1999-01-01

    Following the tradition, the activities of the seven new units created in 1997 on the basis of the former Department of High Energy Physics are presented under a common header, they are: Department of Particle Theory (Dept 5); Department of Leptonic Interactions (Dept 11); Department of Hadron Structure (Dept 12); Department of High Energy Nuclear Interactions (Dept 13); The ALICE Experiment Laboratory (NAL); The ATLAS Experiment Laboratory (NAT); High Energy Physics Detector Construction Group (PBD). The research covers a variety of problems of the experimental and theoretical high energy particle physics: the hadronic and leptonic interactions with nucleons and nuclei (characteristics of particle production, including heavy quark physics), e + e - interactions and tests of the Standard Model (also radiative corrections), ultrarelativistic heavy ion interactions and search for the quark-gluon plasma, as well as the spectra, composition and interactions of high energy cosmic ray particles. Research on detectors and accelerator components as well as the development of the apparatus for the high energy physics experiments at future accelerators: LHC (CERN, Geneva), RHIC (Brookhaven), B-Factory (KEK, Tsukuba) and TESLA (DESY) is also presented. The technology of new materials with unique properties such as carbon-carbon composites is also worked on from the point of view of their application in high energy physics experiments. The Division is located in a separate building on the campus of the University of Mining and Metallurgy (UMM). This location, close to the Jagiellonian University (JU), facilitates the collaboration with the latter and with the UMM. The joint weekly seminars carried out for nearly 40 years prove this long term tradition. A substantial part of the activities is teaching and training students from the academic community in Cracow. Joint research, teaching and academic training in the high energy physics are carried out within the M. Miesowicz

  5. Advertising Emergency Department Wait Times

    Science.gov (United States)

    Weiner, Scott G.

    2013-01-01

    Advertising emergency department (ED) wait times has become a common practice in the United States. Proponents of this practice state that it is a powerful marketing strategy that can help steer patients to the ED. Opponents worry about the risk to the public health that arises from a patient with an emergent condition self-triaging to a further hospital, problems with inaccuracy and lack of standard definition of the reported time, and directing lower acuity patients to the higher cost ED setting instead to primary care. Three sample cases demonstrating the pitfalls of advertising ED wait times are discussed. Given the lack of rigorous evidence supporting the practice and potential adverse effects to the public health, caution about its use is advised. PMID:23599836

    Full text: The educational activities, started in 1998 were successfully continued. About 1000 pupils, age 15 - 20, from high schools and students of various universities from all over Poland visited our Centre of Education and Information (bldg. 67) where the exhibition ''Nuclear wastes: problems, solutions'' is displayed. In addition to the problems specific to nuclear wastes, the visits offer special chance to talk about more general questions connected with environmental radioactivity, radiation risks as well as very basis of the atomic and nuclear radiation. Our staff also helps the pupils (and their teachers as well) visit the most important experimental sites at SINS. In addition to our permanent interest in education on the level of secondary school, the Department organised series of courses which belonged to the continuous education of some professional groups. About 150 officers of the Boarder Guard from all over Poland were trained in the basis of radiological protection, dosimetry and rules which govern the transport of radioactive materials. Almost the same problems were of interest to a group from Polish airline company LOT-CARGO. Another course, which concerned the production of radiopharmaceuticals for nuclear medicine and problems of radiation field in which the mankind lives, was organised for about 70 technicians of nuclear medicine. Last but not least, a new educational program in the high schools caused an interest of the chemistry teachers in the physics and chemistry of radioactive materials. We had the pleasure to organise appropriate course for a group of about 26 teachers from one of Polish counties (siedleckie). One can also mention that a group of 60 students from the University of Warsaw (Interfaculty Study of Environmental Protection) finished training in ecoradiology, which started in 1998. Step by step, in spite of more or less permanent lack of appropriate funds, the Department completes some educational experimental units which

    Full text: In spite of reduced personnel the number of papers published and in press exceeded fifty, almost ten more than a year ago. Another good sign is the growing number of PhD students. The following short reports cover the three major domains of our scientific activities: nuclear, material and atomic physics. Nuclear physics: The structure of light nuclei was investigated, and studies of nuclear reactions induced by heavy ions were performed including experiments at the Heavy Ion Laboratory of Warsaw University. The experiments were carried out in collaboration with scientists from the Institute of Nuclear Research from Kiev, Ukraine. Proton induced reactions on zirconium were investigated theoretically by means of a multistep-direct model extended for the unbound particle - hole states. Good agreement with the experimental data was achieved. Isospin effects in multifragmentation of relativistic heavy ions were studied by the ALADIN Collaboration. Elements of a new generation detector PANDA were tested experimentally using a proton beam provided by the C-30 compact cyclotron at Swierk. Evidence of a narrow baryon state was found in a quasi - real photoproduction on the deuterium target by the HERMES Collaboration. Atomic physics: Ionisation of selected heavy elements by sulphur ions was investigated in collaboration with the Swietokrzyska Academy, Kielce. Materials research: Hydrogen release from ultrahigh molecular weight polythene was investigated by means of an α - particle beam from the Van de Graaff accelerator of our Department. Last but not least, many of our colleagues have been involved in education. Lectures on nuclear physics, accelerators, detectors used in nuclear research as well as nuclear methods applied in solid state studies for students from many high schools of Warsaw and for students of Warsaw University were given by Dr. Andrzej Korman and Dr. Lech Nowicki. Also, our Department made a significant contribution to the 7 th Science

    In 2005 the Department held a steady course. Topics of nuclear physics, atomic physics and materials research that started in previous years were continued. Although our team was smaller than years ago, the scientific activity, estimated by number of published papers is still very high. Scientists of the Department are co-authors or authors of more than 50 papers. Nuclear physics, which is our main-stream activity, covered a wide energy range. It started close to the Coulomb barrier, where 6 He breakup on heavy nuclei were studied, and ended at zones of tens of GeV; such high energies were used to investigate spin structure of deuterons and to explore hadron leptoproduction. Traditionally, experimental investigations in the fields of atomic physics and of physics of materials completed the scene. Our old Van de Graaff accelerator Lech was used for studies of M-shell ionisation of heavy elements, for hardening of Ultra-High Molecular Weight Polyethylene and for characterisation of materials with RBS and NRA techniques. The VdG runs perfectly although it is over 40 years old. Two Ph.D. students finished their theses and were promoted. Izabela Fijal's work concerned multi-ionization and intrashell coupling effects for L-shell x-ray emission induced by heavy ions, while Sergiy Mezhevych showed studies on scattering of 11 B from carbon isotopes. It is obvious that contemporary works on physics do not arise in a single lab. Our contributions to many papers were possible due owing to collaborations involving many institutions. Some of them are listed: GSI, Darmstadt (PANDA Collaboration) DESY, Hamburg (HERMES Collaboration) Institut fuer Kernphysik, Forschungszentrum Juelich Forschungszentrum Rossendorf CSNSM, Orsay GANIL, Caen University of Huelva Institute of Nuclear Research, Kiev SLCJ, Warsaw ITME, Warsaw Some of our colleagues traditionally gave lectures and made physical demonstrations on Warsaw informal learning events: 9 th Science Picnic and 9 th Science Festival

    Rybicki, K.

    2002-01-01

    Full text: Our Department has evolved from the Laboratory of Electronic Particle Detectors (originally called the Laboratory of Filmless Detectors) founded in 1972. The department is involved in two running experiments (H1 at DESY and Belle at KEK). In 2000 the DELPHI experiment has finished a decade of successful running. The analysis of collected data will continue for a couple of years. Since 1999 our group is a member of the LHC-b experiment at CERN. In addition, a few department members work part-time for the ATLAS collaboration at CERN, and our engineers as well as technicians have been working for several years on the construction and testing of superconducting cavities for the TESLA project. This arrangement provides a neat equilibrium between data analysis, running experiments and work on future projects. The main results of work done in 2001 are covered in reports on research. Here we mention only a few highlights: * The Belle experiment demonstrated a strong CP violation in B 0 d decays. The measured asymmetry was sin(2φ 1 ) 0:99 ±0:14±0:06. This is the first (together with the BaBar experiment at SLAC) observation of the CP violation outside the K 0 sector. * The DELPHI collaboration (together with other LEP experiments) determined very precisely the parameters of the Standard Model in the electroweak sector and showed the strongest limit on the direct Higgs search i.e. m H >114 GeV. * The H1 experiment has measured the cross section for the b quark production to be much larger than the NLO QCD predictions. This is especially surprising in Deep Inelastic ep Scattering where the predictions should be fairly solid. * The Cracow LHCb group has designed and tested the prototype of the outer tracker. One should also mention high-quality carbon-carbon composites designed and produced in collaboration with the High Energy Physics Detector Construction Group. In 2001 there were 43 papers (meeting the highest Polish State Committee for Scientific Research

  15. Population growth and economic growth.

    Narayana, D L

    1984-01-01

    This discussion of the issues relating to the problem posed by population explosion in the developing countries and economic growth in the contemporary world covers the following: predictions of economic and social trends; the Malthusian theory of population; the classical or stationary theory of population; the medical triage model; ecological disaster; the Global 2000 study; the limits to growth; critiques of the Limits to Growth model; nonrenewable resources; food and agriculture; population explosion and stabilization; space and ocean colonization; and the limits perspective. The Limits to Growth model, a general equilibrium anti-growth model, is the gloomiest economic model ever constructed. None of the doomsday models, the Malthusian theory, the classical stationary state, the neo-Malthusian medical triage model, the Global 2000 study, are so far reaching in their consequences. The course of events that followed the publication of the "Limits to Growth" in 1972 in the form of 2 oil shocks, food shock, pollution shock, and price shock seemed to bear out formally the gloomy predictions of the thesis with a remarkable speed. The 12 years of economic experience and the knowledge of resource trends postulate that even if the economic pressures visualized by the model are at work they are neither far reaching nor so drastic. Appropriate action can solve them. There are several limitations to the Limits to Growth model. The central theme of the model, which is overshoot and collapse, is unlikely to be the course of events. The model is too aggregative to be realistic. It exaggerates the ecological disaster arising out of the exponential growth of population and industry. The gross underestimation of renewable resources is a basic flaw of the model. The most critical weakness of the model is its gross underestimation of the historical trend of technological progress and the technological possiblities within industry and agriculture. The model does correctly emphasize

    , this thesis deals with some of the aspects of hyphal growth, which is an important virulence factor for pathogenic fungi infecting both humans and plants. Hyphal establishment through continuous polar growth is a complex process, requiring the careful coordination of a large subset of proteins involved...... in polarity establishment and maintenance, cytoskeleton dynamics and intracellular transport. The first part of this thesis addresses the A. gossypii Arf3 small GTPase and its GEF- and GAP regulators; Yel1 and Gts1, which has been implicated in polar growth in a wide range of organisms. We could demonstrate......-regulatory activity of AgGts1, the protein could have additional actin organizing properties. In the second and third part, this thesis addresses the use of A. gossypii and its relative E. cymbalariae as model organisms for filamentous growth.

    State and local health departments are witnessing growth in the area of informatics. As new informatics projects commence, existing methods of communication within the health department may not be sufficient. We gathered information about roles and communication between a development team and a user group working simultaneously on an informatics project in a state public health department in an effort to better define how communication and role definition is best used within an informatics project.

    Full text: Following our long-time tradition we will present under a common header the activities of the seven new units created in 1997 on the basis of the former Department of High Energy Physics: Department of Particle Theory (Dept. V); Department of Leptonic Interactions (Dept XI); Department of Hadron Structure (Dept XII); Department of High Energy Nuclear Interactions (Dept XIII); The ALICE Experiment Laboratory (NAL); The ATLAS Experiment Laboratory (NAT); High Energy Physics Detector Construction Group (PBD). At the end we will list our common activities: lectures and courses as well as seminars. Our research covers a variety of problems of the experimental and theoretical high energy particle physics: the hadronic and leptonic interactions with nucleons and nuclei (characteristics of particle production, including heavy quark physics), e + e - interactions and tests of the Standard Model (also evaluation of radiative corrections), ultrarelativistic heavy ion interactions and search for the quark-gluon plasma, as well as the spectra, composition and interactions of high energy cosmic ray particles. Research on detectors and accelerator components as well as the development of the apparatus for the high energy physics experiments at future accelerators: LHC (CERN, Geneva), RHIC (Brookhaven), B-Factory (KEK, Tsukuba) and TESLA (DESY, Hamburg) is also carried out. The technology of new materials with unique properties such as carbon-carbon composites is also worked on from the point of view of their application in high energy physics experiments. The Division is located in a separate building on the campus of the University of Mining and Metallurgy. This location, close to the Jagiellonian University, facilitates the collaboration with the latter and with the University of Mining and Metallurgy. The joint weekly seminars carried out for nearly 40 years prove this long term tradition. A substantial part of our activities is teaching and training students from

    Full text: The last year of the twentieth-century was productive for our Department. Although the name of the Department suggests that we are all involved in investigations of nuclear reactions, in fact our activities are spread over three major domains: nuclear, atomic and material physics. Some of the projects we were involved in the last year have been realized using national facilities and accelerators, like the Van de Graaff accelerator of our Department at 69 Hoza Street, Warsaw Cyclotron U-200P of Warsaw University, and compact C30 cyclotron of our Institute at Swierk. Other projects were done abroad, using facilities of the Gesellschaft fuer Schwerionenforschung in Darmstadt, Institute de Physique Nucleaire at Orsay, and Universitaet Erlangen-Nuernberg in Erlangen. We carried out our work in close collaborations with physicists from many laboratories, Polish and foreign. - Low energy nuclear reactions. In collaboration with scientists from Ukraine experiments, using heavy ion beam provided by the Warsaw Cyclotron, were started. The aim of the experiments is to study nuclear reactions leading to the exotic light nuclei in exit channels and energy dependence of the nucleus - nucleus interaction. Efforts were made to develop a multistep direct model of nuclear reactions. In the model contributions due to the low energy collective excitations were taken into account. Good agreement with the experimental data was achieved. - Multifragmentation of relativistic heavy ions. ALADIN Collaboration studied multifragmentation reactions induced by relativistic heavy ions. The main activities of our scientists concentrated on an upgrade of the detecting system in order to replace photo multipliers with large area avalanche photodiodes in the central section of the TOF-wall. Some tests of the photodiodes manufactured by Advanced Photonix Inc. were performed using standard β - and γ-sources. - Structure of a nucleon. Decay properties of the Roper resonance were studied.

    Full text: The Department of Nuclear Reactions had a very productive year. The following reports cover three major domains of our activities: nuclear, material and atomic physics. One of the current questions in modern nuclear physics is question of the phase transitions in nuclear matter. Our physicists, the members of the ALADIN Collaboration at Gesellschaft fuer Schwerionenforschung, participated in new experiments exploring properties of highly excited nuclear matter and the phenomenon of the liquid - gas phase transition. The experiments yielded a number of important results. Details can be found in the three short reports presented in this volume. Structure of a nucleon is another important subject of nuclear science research. In the last year energy region of Δ resonance has been investigated by means of charge exchange reaction. The experiment was performed at Laboratory National Saturne in Saclay by SPESIV-π collaboration consisting of physicist from Institute of Nuclear Physics Orsay, Niels Bohr Institute Copenhagen and from our Department. The main achievement of the experiment was evidence for a Δ - hole attraction in the spin longitudinal channel. Reactions induced by radioactive ion beams such as 6 He recently attract a lot of interest. There exist some evidences that the 6 He nucleus has a two-neutron halo structure similar to that well established for 11 Li. An analysis of 6 He + 4 He scattering data reported in this volume revealed some similarities between the loosely bound 6 Li nucleus and the neutron rich 6 He. Research in material physics has focused on two basic topics: a crystallographic model of uranium dioxide, a material currently used as a nuclear fuel and transformations of defects in GaAs crystals at low temperature. The investigations have been carried out in a wide collaboration with scientists from the University of Jena, Research Center Karlsruhe and Centre de Spectrometrie Nucleaire Orsay. Some experiments have been performed at

Our colleagues led by Prof. Pawel Zupranski joined a large international collaboration HERMES and took part in experiments at DESY devoted to the study of the spin structure of the nucleon. Another group directed by Associate Prof. Bogdan Zwieglinski has worked on a conceptual design of a new generation detector PANDA (Proton-Antiproton Detection) which will be used in future experiments at GSI. Moreover, the experimental programmes covering three major domains of our scientific activities: nuclear physics, materials research and atomic physics were continued. - Nuclear physics: Experimental studies of nuclear reactions induced by heavy ions provided by the Warsaw U-200P Cyclotron were performed in collaboration with scientists from the Institute for Nuclear Studies in Kiev, Ukraine. The aim of the experiments was to investigate isotopic effects in the scattering of 11 B from carbon nuclides. Also, excited states of 6 Li predicted theoretically but never seen in experiments were investigated by means of one-neutron transfer reactions. Proton induced reactions were investigated theoretically by means of the multistep-direct model. Good agreement with the experimental data was achieved. The mechanism of fragments production in collisions of 197 Au with a gold target in the wide range of energies was studied by ALADIN and INDRA Collaborations. The production of η mesons from proton - proton collisions was investigated experimentally at the Juelich Cooler Synchrotron COSY. - Atomic physics: The ionisation of Au, Bi, Th and U atoms by Si ions was investigated in collaboration with the Swietokrzyska Academy, Kielce, and the University of Erlangen-Nuernberg. - Materials research: The sensitivity of the Solid State Nuclear Track PM-355 detectors was tested against intensive gamma and electron radiation.

    (full text) During the last year our activities were spread over the three major domains: nuclear, atomic and material physics. The nuclear physics experimental programme covered a broad range of nuclear reactions induced by light and heavy ions. New experiments were performed at the compact C-30 cyclotron at Swierk, at University of Jyvaeskylae, GSI Darmstadt, LN Saturne. Prospects for future experiments on nucleon structure at Forschungszentrum Juelich were open. The collaboration with INR Kiev was tightened and work was done in order to prepare experiments at the C-200 heavy ion cyclotron in Warsaw. An effort to install the ion guide isotope separator on line (IGISOL) at the C-200 cyclotron has also to be mentioned A half a year stay of Dr. Nicholas Keeley in the Department, who received The Royal Society/Polish Academy of Science grant, resulted in many interesting results on breakup of light nuclei. Details can be found in the short abstracts presented in this report. As far as atomic physics is concerned, the activity of a group lead by Prof. Marian Jaskola yielded various new results. The experiments were performed at the University of Erlangen, in close collaboration with the Pedagogical University in Kielce and the University of Basel. Fast neutrons generated in the 3 H(d,n) 4 He reaction induced by the 2 MeV deuteron beam from the Van der Graaff accelerator at the Department were used to calibrate solid state-nuclear-track detectors. This was a very good year for material physics research: Jan Kaczanowski and Slawomir Kwiatkawski received Ph.D. degrees based on dissertation research performed in the material physics research programme, while Pawel Kolodziej completed his MSc. thesis in collaboration with the Institute of Electronic Materials Technology in Warsaw, Research Center Karlsruhe, University of Jena and CSNSM Orsay many results were obtained.

Experimental programme of the near-threshold meson production in proton - proton scattering has been started in collaboration with Forschungszentrum. Juelich. * Atomic physics: Spectra of the X-rays emitted by energetic sulphur ions scattered off carbon atoms were analysed in order to study the role of the multiple charge states of the inner shells in the dynamics of the collision process. Ionization probabilities in collision of oxygen ions with gold atoms were measured. The observed disagreement of the experimental data with the theoretical predictions suggest a strong effect generated by the sub-shell couplings. * Materials research: Ion channelling method was applied to investigate transformation of the defects in Al x Ga 1-x As crystalline layers.

    Candelpergher, Bernard

    2017-01-01

    The aim of this monograph is to give a detailed exposition of the summation method that Ramanujan uses in Chapter VI of his second Notebook. This method, presented by Ramanujan as an application of the Euler-MacLaurin formula, is here extended using a difference equation in a space of analytic functions. This provides simple proofs of theorems on the summation of some divergent series. Several examples and applications are given. For numerical evaluation, a formula in terms of convergent series is provided by the use of Newton interpolation. The relation with other summation processes such as those of Borel and Euler is also studied. Finally, in the last chapter, a purely algebraic theory is developed that unifies all these summation processes. This monograph is aimed at graduate students and researchers who have a basic knowledge of analytic function theory.

    The present disclosure is directed to heat recovery systems that employ two or more organic Rankine cycle (ORC) units disposed in series. According to certain embodiments, each ORC unit includes an evaporator that heats an organic working fluid, a turbine generator set that expands the working fluid to generate electricity, a condenser that cools the working fluid, and a pump that returns the working fluid to the evaporator. The heating fluid is directed through each evaporator to heat the working fluid circulating within each ORC unit, and the cooling fluid is directed through each condenser to cool the working fluid circulating within each ORC unit. The heating fluid and the cooling fluid flow through the ORC units in series in the same or opposite directions.

    2006-01-01

    Objective: Department of Defense (DoD) chiropractic internships first began in July of 2001. At the time of this study, 30 New York Chiropractic College student interns had completed part of their clinical education within chiropractic clinics at either the National Naval Medical Center or Naval Hospital Camp Lejeune. The purpose of this study was to evaluate and compare the careers of DoD chiropractic internship participants with comparable nonparticipants in terms of demographics, professional activities, income, and satisfaction. Methods: Survey research was employed to gather data from DoD chiropractic internship participants and comparable nonparticipants. Statistical analysis was carried out to determine significant differences with a nominal significance level set as.05. Results: There were no statistically significant differences in demographics, professional activities, income, or career satisfaction between the 21 DoD chiropractic internship participants (70% response rate) and 35 internship nonparticipants (35% response rate). Conclusions: This study utilized practice parameters as a form of feedback for a comparative analysis of DoD chiropractic internship participants and nonparticipants and found no significant differences between these groups. Limitations of the study may have influenced the results. Opportunities for chiropractic students to train within these settings remains limited and should be further explored, as should additional research into this component of chiropractic clinical education.

    Full text: The contributions given hereafter to this Annual Report cover a broad activity of the Department in 1999 both in the pure nuclear spectroscopy and in the applied spectroscopy investigations. That activity is then assembled in the two main groups: the nuclear structure studies with the application of the multidetector systems such as GASP, GAMMASPHERE, EUROBALL and the RFD - as its ancillary device, and investigations of condensed matter properties with the use of nuclear methods. In addition, non-nuclear methods such as the atomic force microscopy provided several new encouraging results. The nice data obtained are due to the great skill and hard work of all members of the staff, and a vast cooperation both with international and national institutes and institutions. When anticipated for calling the attractive results of the past year, I would rather admit that all data given here pretend to be those. To meet with, I refer directly to the short presentations given in the next pages. (author)

    Emergency department (ED) overcrowding has been a serious issue on the national agenda for the past 2 decades and is rapidly becoming an increasingly significant problem for children. The goal of this report is to focus on the issues of overcrowding that directly impact children. Our findings reveal that although overcrowding seems to affect children in ways similar to those of adults, there are several important ways in which they differ. Recent reports document that more than 90% of academic emergency medicine EDs are overcrowded. Although inner-city, urban, and university hospitals have historically been the first to feel the brunt of overcrowding, community and suburban EDs are now also being affected. The overwhelming majority of children (92%) are seen in general community EDs, with only a minority (less than 10%) treated in dedicated pediatric EDs. With the exception of patients older than 65 years, children have higher visit rates than any other age group. Children may be at particularly increased risk for medical errors because of their inherent variability in size and the need for age-specific and weight-based dosing. We strongly recommend that pediatric issues be actively included in all future aspects of research and policy planning issues related to ED overcrowding. These include the development of triage protocols, clinical guidelines, research proposals, and computerized data monitoring systems.

    Full text: The research activity of our department concerns structural and dynamical properties of molecular solids. The particular subjects of interest in the year 2000 were orientational and conformational disorder on organic materials and the magnetism of new molecular and intermetallic compounds. The experimental work in our department relies on the complementary use of large instruments at international research centres and of the equipment operating in our laboratories. In the neutron scattering studies (ICNS inelastic coherent neutron scattering, IINS inelastic incoherent neutron scattering, QNS quasielastic neutron scattering etc) we mostly avail ourselves of neutron sources of The Institute for Energy Technology (IFE), Kjeller, Norway, and of The Joint Institute for Nuclear Research (JINR) Dubna, Russia. Our proposals are also regularly accepted in the other neutron centres such as Leon Brillouin Laboratory (LLB) Saclay, France, Rutherford Appleton Laboratory (RAL) Oxford, UK. etc. Thermodynamic characteristics of the materials are determined in our calorimetric laboratory equipped with adiabatic and differential scanning calorimeters. It is due to the invention of our researchers that these instruments, partly prototypic, are now capable of providing quantitative results on the kinetic behaviour of materials out of equilibrium. The scanning mode operation of our upgraded Fourier-transform infrared spectrometer allows US to follow the evolution of the dynamics of a material in the real time and in the temperature range 10-310 K. Textures arising in phase transitions are observed with the use of the polarising microscope with temperature-controlled stage. Molecular reorientation motions and relaxation processes are studied in the dielectric measurements. The laboratory of magnetic research possesses a set of modern instruments for measurements of magnetisation and of the AC susceptibility operating down to the helium temperatures.

  12. Key parameters controlling radiology departments

    International Nuclear Information System (INIS)

    Busch, Hans-Peter

    2011-01-01

    For radiology departments and outstanding practises control and optimization of processes demand an efficient management based on key data. Systems of key data deliver indicators for control of medical quality, service quality and economics. For practices effectiveness (productivity), for hospitals effectiveness and efficiency are in the focus of economical optimization strategies. Task of daily key data is continuous monitoring of activities and workflow, task of weekly/monthly key data is control of data quality, process quality and achievement of objectives, task of yearly key data is determination of long term strategies (marketing) and comparison with competitors (benchmarking). Key parameters have to be defined clearly and have to be available directly. For generation, evaluation and control of key parameters suitable forms of organization and processes are necessary. Strategies for the future will be directed more to the total processes of treatment. To think in total processes and to steer and optimize with suitable parameters is the challenge for participants in the healthcare market of the future. (orig.)

    During our recent information meetings, we discussed four topics: the new Saved Leave Scheme (LTSLS); the new developments concerning pensions; the MARS Advancement and Promotion scheme and its 2012 budget; the recently updated Administrative and Operation Circulars. These meetings were attended by a large number of staff members and were a great opportunity for the Staff Association to engage in direct dialogue with the staff in the various departments. The vast majority of questions or comments were on the LTSLS and on the possibility to save leave, which is to be taken at the end of a career.  A few comments were also made on MARS, a system many considered to be not very motivating and that takes up a lot of resources for minimal positive results. Thanks and encouragement After the presentation on Pensions, on behalf of the Staff Association we thanked Dorothée Duret, who for personal reasons had to resign from the Pension Fund Governing Board (PFGB) and from the Staff Council...

    We use the AdS/CFT correspondence to study the resummation of a perturbative genus expansion appearing in the type II superstring dual of ABJM theory. Although the series is Borel summable, its Borel resummation does not agree with the exact non-perturbative answer due to the presence of complex instantons. The same type of behavior appears in the WKB quantization of the quartic oscillator in Quantum Mechanics, which we analyze in detail as a toy model for the string perturbation series. We conclude that, in these examples, Borel summability is not enough for extracting non-perturbative information, due to non-perturbative effects associated to complex instantons. We also analyze the resummation of the genus expansion for topological string theory on local ℙ{sup 1}×ℙ{sup 1}, which is closely related to ABJM theory. In this case, the non-perturbative answer involves membrane instantons computed by the refined topological string, which are crucial to produce a well-defined result. We give evidence that the Borel resummation of the perturbative series requires such a non-perturbative sector.

    Full text: The Department of Training and Consulting is a training centre for high-school students and their teachers, for students of physics and natural sciences in general, last but not least for society broadly understood, including professionals dealing with nuclear radiation. In 2002 the Department was visited by about 5000 high-school students who could listen to the lectures, and take part in experimental demonstrations on ionising radiation, its role in everyday life, technical and medical applications. In addition, the Department led the radiation protection course for the accelerators' operators employed by the Institute for Nuclear Studies. One-day courses on physics of radiation were also arranged for teachers. The Laboratory of Atomic and Nuclear Physics for Schools is still developing. The Laboratory permits high-school students to make simple experiments of qualitative and quantitative character. Its main purpose is to teach the elements of experimental work. In addition, university students of physics can conduct quite complicated experiments. Indeed, the Laboratory is also used for this purpose. The actual list of experiments available to students includes: the behaviour of charged particles in electric and magnetic fields, excitation and properties of photoluminescence, production and properties of X-rays, wave-particle duality, properties of alpha, beta and gamma radiation, elements of gamma spectroscopy including identification of elements by means of induced X-ray fluorescence. The first experience gathered recently is positive although there is still some work to do in order to make the Laboratory more educational. In particular, one of the conclusions drawn from our meetings at the instruments is that although high-school students can follow instructions and understand briefly the physical processes, they are not prepared for reporting the results of the observations or experiments. It is clear that we have to help them in overcoming this

    To establish a system of differential diagnosis for vertigo/dizziness at the Emergency Department (ED), careful history-taking of complications and examinations of nystagmus should be helpful and therefore prepared by ED staff. Vertigo/dizziness could come from various kinds of organs for equilibrium, sometimes resulting in an emergency due to the central origin. In the present study, we checked patients' background data at the ED in advance of a definitive diagnosis at the Department of Otolaryngology and examined the significance of the correlation between the data and the diagnosis. We studied a series of 120 patients with vertigo/dizziness, who visited the Departments of Emergency and Otolaryngology between April 2011 and March 2012. At the ED, we first checked patients' backgrounds and carried out neurologic and neuro-otologic examinations. At the Department of Otolaryngology, we finally diagnosed all the patients according to the criteria and classified the origins of vertigo/dizziness into central and non-central diseases. The ratio of patients with disease of central origin was 12.5% and that for non-central origin was 87.5%. The risk factors for cerebrovascular disease such as hypertension, heart disease, and diabetes were also the risk factors for central vertigo/dizziness by the chi-squared test. To predict a central origin for vertigo/dizziness, only gaze nystagmus was the significant factor by multivariate regression analysis.

    Full text: The Department of Nuclear Theory consists of 18 physicists and 3 graduate students working on different aspects of low energy, high energy, plasma and nonlinear physics. Most of the effort is phenomenologically oriented. Close collaboration with SMC, LEAR and ALICE Collaborations at CERN must be also emphasized. The specific topics are: Studies of strangeness in nuclei stem from a long Warsaw tradition of hypernuclear physics. These include attempts to understand the elusive Σ-hypernuclei, studies of nuclear bound states of η-mesons that introduce hidden strangeness into nuclei. Some studies have been devoted to the structure of superheavy elements, which resulted in predicting properties of deformed superheavy nuclei. They are continued with calculations of collective motion, neutron haloes and energy dissipation in heavy ion collisions. An increasing effort is also devoted to research on nuclear collisions at high energies. Much attention is paid to the study of the mass of exotic nuclei. Studies in high energy physics are devoted to understanding deep inelastic lepton scattering, formal properties of the contour gauge theories, the phenomenology of high energy multiparticle and production processes in both hadronic and nuclear collisions, (especially the systematics of leading particle production in these processes). A new approach to the standard model via conformed unification of general relativity has been attempted. The new attempt at quantization of nonlinear theories has been undertaken and first positive and interesting results obtained. Theoretical studies of soliton solutions in several branches of physics are performed. Methods of testing the stability and metamorphosis of these soliton solutions have been developed. Results have implications in solid state physics as well as for plasmas and hydrodynamics. Collaborations with several universities have been maintained. These include the Universities of Warsaw, Bucharest, Kielce, T.U. Munich

  1. Pharmaceutical advertising in emergency departments.

    Promotion of prescription drugs represents a growing source of pharmaceutical marketing expenditures. This study was undertaken to identify the frequency of items containing pharmaceutical advertising in clinical emergency departments (EDs). In this observational study, emergency physician on-site investigators quantified a variety of items containing pharmaceutical advertising present at specified representative times and days, in clinical EDs. Measurements were obtained by 65 on-site investigators, representing 22 states. Most EDs in this study were community EDs (87% community and 14% university or university affiliate), and most were in urban settings (50% urban, 38% suburban, and 13% rural). Investigators measured 42 items per ED (mean = 42; median = 31; interquartile range of 14-55) containing pharmaceutical advertising in the clinical area. The most commonly observed items included pens (mean 15 per ED; median 10), product brochures (mean 5; median 3), stethoscope labels (mean 4; median 2), drug samples (mean 3; median 0), books (mean 3.4), mugs (mean 2.4), and published literature (mean 3.1). EDs with a policy restricting pharmaceutical representatives in the ED had significantly fewer items containing pharmaceutical advertising (median 7.5; 95% CI = 0 to 27) than EDs without such a policy (median 35; 95% CI = 27 to 47, p = 0.005, nonparametric Wilcoxon two-sample test). There were no differences in quantities of pharmaceutical advertising for EDs in community compared with university settings (p = 0.5), rural compared with urban settings (p = 0.3), or annual ED volumes (p = 0.9). Numerous items containing pharmaceutical advertising are frequently observed in EDs. Policies restricting pharmaceutical representatives in the ED are associated with reduced pharmaceutical advertising.

    The scientific activity of our department is traditionally focused on nuclear physics, atomic physics and material research. Our interest in nuclear physics is broad, ranging from the structure of a nucleon to the structure of the nucleus. The spin structure of a nucleon has been investigated within the HERMES Collaboration which comprises 32 institutions from 11 countries. The collaboration performs experiments at Deutches Elektronen-Synchrotron in Hamburg. Another large-scale international collaboration we are participating in is PANDA. The PANDA (antiProton ANnihilation at DArmstadt) experiment will be installed at the High Energy Storage Ring for antiprotons of the future Facility for Antiproton and Ion Research (FAIR) in Darmstadt. Our colleagues, led by Dr. B. Zwieglinski, have been working on the concept of a calorimeter, testing different scintillators. Many experiments in low energy nuclear physics were performed in collaboration with University of Jyvaeskylae, the Institute of Nuclear Research of the Ukrainian Academy of Science and Heavy Ion Laboratory of the Warsaw University. They were devoted to studying nucleus-nucleus interactions near the Coulomb barrier. This year, atomic studies focused on the L-shell ionisation of some heavy elements by silicon ions accelerated to the energy of 8.5-36 MeV. The results are presented in this report and are compared to different model calculations. Finally, I take great pleasure in congratulating Dr. L. Nowicki, whose study of uranium oxide structure, performed in collaboration with Centre de Spectrometrie Nucleaire et de Spectrometrie de Masse in Orsay, was chosen as an important scientific achievement of our Institute in 2006. Apart from purely scientific activities, a few of our colleagues have been involved in education, giving lectures to students from high schools in Warsaw and Warsaw University. R. Ratajczak contributed to the 10 th Science Festival, an event organized for the general public every year

  3. Time series analysis of temporal networks

    A common but an important feature of all real-world networks is that they are temporal in nature, i.e., the network structure changes over time. Due to this dynamic nature, it becomes difficult to propose suitable growth models that can explain the various important characteristic properties of these networks. In fact, in many application oriented studies only knowing these properties is sufficient. For instance, if one wishes to launch a targeted attack on a network, this can be done even without the knowledge of the full network structure; rather an estimate of some of the properties is sufficient enough to launch the attack. We, in this paper show that even if the network structure at a future time point is not available one can still manage to estimate its properties. We propose a novel method to map a temporal network to a set of time series instances, analyze them and using a standard forecast model of time series, try to predict the properties of a temporal network at a later time instance. To our aim, we consider eight properties such as number of active nodes, average degree, clustering coefficient etc. and apply our prediction framework on them. We mainly focus on the temporal network of human face-to-face contacts and observe that it represents a stochastic process with memory that can be modeled as Auto-Regressive-Integrated-Moving-Average (ARIMA). We use cross validation techniques to find the percentage accuracy of our predictions. An important observation is that the frequency domain properties of the time series obtained from spectrogram analysis could be used to refine the prediction framework by identifying beforehand the cases where the error in prediction is likely to be high. This leads to an improvement of 7.96% (for error level ≤20%) in prediction accuracy on an average across all datasets. As an application we show how such prediction scheme can be used to launch targeted attacks on temporal networks. Contribution to the Topical Issue

    2017-12-01

    Interferometric synthetic aperture radar (INSAR) data have revealed signals associated with the recent DPRK events in 2016 and 2017. These signals include decorrelation and indications of subsidence. Both standard phase differences and amplitude offsets are calculated. We show results of INSAR analysis as conducted using C and L band data and investigate the causes of the decorrelation (e.g. subsidence, landslide, or spall) and compare the observed signal with numerical models of deformation and seismic observations. A time series approach is applied to constrain post-event deformation at the weeks to months' timescale. We compare the INSAR observations of the DPRK tests with previous observations of events at other source regions using ERS archive data, which revealed a variety of post-seismic signatures. The signatures are evaluated with respect to the known geology and causes, including long-term surface relaxation and possible groundwater/thermal effects. Particular focus is on the sites on Pahute and Rainier Mesa, which displayed long-term subsidence signals that extended for several years after the explosions. This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. Lawrence Livermore National Security, LLC

    More than a century ago, Ortner described a case of cardiovocal syndrome wherein he attributed a case of left vocal fold immobility to compression of the recurrent laryngeal nerve by a dilated left atrium in a patient with mitral valve stenosis. Since then, the term Ortner's syndrome has come to encompass any nonmalignant, cardiac, intrathoracic process that results in embarrassment of either recurrent laryngeal nerve-usually by stretching, pulling, or compression; and causes vocal fold paralysis. Not surprisingly, the left recurrent laryngeal nerve, with its longer course around the aortic arch, is more frequently involved than the right nerve, which passes around the subclavian artery. To discuss the pathogenesis of hoarseness resulting from cardiovascular disorders involving the recurrent laryngeal nerve along with the findings of literature review. This paper reports a series of four cases of Ortner's syndrome occurring due to different causes. Case study. Ortner's syndrome could be a cause of hoarseness of voice in patients with cardiovascular diseases. Although hoarseness of voice is frequently encountered in the Otolaryngology outpatient department, cardiovascular- related hoarseness is an unusual presentation. Indirect laryngoscopy should be routinely performed in all cases of heart disease.

    Full Text Available Ameloblastic carcinoma is a rare odontogenic tumor exhibiting not only features of ameloblastoma but also features of carcinoma in either or both primary and metastatic lesions. Clinical features of this lesion are more aggressive and rapid than those of ameloblastoma. At times, it can metastasize to the lung or regional lymph nodes. Histologically, there is a picture of both ameloblastoma and carcinoma. Treatment is aggressive and has to be designed for each individual patient. English literature is sparse for this condition, as fewer cases have been reported till date. We report a series of four cases with different treatment modalities.

    Full text: The year 1998 can be considered as very successful both in harvesting important results from the existing collaborations as well as establishing new ones. In the frame of the COSY-11 collaboration cross section for η' production in p-p collision close to the threshold has been measured. In the region of excess energy between 1.5 and 4.1 MeV the η' cross sections are much lower than those of the π 0 and η production. There seems to be no indication that N * resonance doorway-like state governs the reaction mechanisms. The determined coupling constant g η'pp appears to be consistent with the prediction of the simple quark model. Results were published in Phys. Rev. Letters. Using the GEM detector, investigations of the isospin symmetry breaking were performed. Two reactions channels 3 Heπ 0 and 3 Hπ + from the reaction at proton momenta 700, 767, and 825 MeV/c were measured. Data analysis is in progress. The model of the meson cloud in the nucleon which is a speciality of our department has been successfully applied to explain the leading proton and neutron cross sections from the e + or e - proton collisions at the HERA ring. General formulas to calculate polarization of the particles with spin transmitted through the barrier in the presence of strong magnetic fields were obtained. New collaboration between our laboratory and the Institute for Nuclear Research in Kiev has been established. One PhD thesis was completed in the frame of this collaboration. We joined the new collaboration with Lund University concerning studies of hot nuclear matter properties using heavy ions from CELSIUS ring. First test of the phoswich detector for the forward wall was performed in Uppsala. Isoscalar giant dipole resonance strength distribution 3 ℎω has been evaluated in 208 Pb in the space of 1p1h and 2p2h excitation. The centroid energy of this state can directly be related to the nuclear incompressibility module. Our result indicates rather large values of

  12. A Time Series Forecasting Method

    Directory of Open Access Journals (Sweden)

    Wang Zhao-Yu

    2017-01-01

    Full Text Available This paper proposes a novel time series forecasting method based on a weighted self-constructing clustering technique. The weighted self-constructing clustering processes all the data patterns incrementally. If a data pattern is not similar enough to an existing cluster, it forms a new cluster of its own. However, if a data pattern is similar enough to an existing cluster, it is removed from the cluster it currently belongs to and added to the most similar cluster. During the clustering process, weights are learned for each cluster. Given a series of time-stamped data up to time t, we divide it into a set of training patterns. By using the weighted self-constructing clustering, the training patterns are grouped into a set of clusters. To estimate the value at time t + 1, we find the k nearest neighbors of the input pattern and use these k neighbors to decide the estimation. Experimental results are shown to demonstrate the effectiveness of the proposed approach.

    An increasing number of algorithms for biochemical network inference from experimental data require discrete data as input. For example, dynamic Bayesian network methods and methods that use the framework of finite dynamical systems, such as Boolean networks, all take discrete input. Experimental data, however, are typically continuous and represented by computer floating point numbers. The translation from continuous to discrete data is crucial in preserving the variable dependencies and thus has a significant impact on the performance of the network inference algorithms. We compare the performance of two such algorithms that use discrete data using several different discretization algorithms. One of the inference methods uses a dynamic Bayesian network framework, the other-a time-and state-discrete dynamical system framework. The discretization algorithms are quantile, interval discretization, and a new algorithm introduced in this article, SSD. SSD is especially designed for short time series data and is capable of determining the optimal number of discretization states. The experiments show that both inference methods perform better with SSD than with the other methods. In addition, SSD is demonstrated to preserve the dynamic features of the time series, as well as to be robust to noise in the experimental data. A C++ implementation of SSD is available from the authors at http://polymath.vbi.vt.edu/discretization .

    Fuji Electric Co. developed a series of dispensers (FTS-50W and FTM-50W) which enables the sale of a plurality of drinks by one machine by making a beer dispenser and a carbonated drink dispenser monolithic. Main characteristics are as follows. Beer and carbonated drink (soft drinks and alcohols such as shochu) can be sold by one machine (FTS is for 1 flavor and FTM is for 3 flavor). It has a portion function which enables the quantitative sale of carbonated drink just by pressing a button, and also has a function which enables only the sale of carbonated water. The cost reduction can be realized by standardizing the parts of other beer dispensers and soft drink dispensers. (NEDO)

    Research at the Department of Nuclear Radiospectroscopy concerns various aspects of the NMR and its applications to solids and to biosystems. The research activity covers: investigation of molecular dynamics and structures in solids using NMR spectroscopy, and investigation of humans, animals and plants using NMR imaging and localized spectroscopy. The MR Laboratory is equipped with a 7.05 T wide bore vertical superconducting magnet (SCM) with a pulse spectrometer. It allows to measure of deuteron NMR spectra at T ≥ 5 K. NMR high resolution spectra for 29 Si, 11 B, 27 Al and 31 P nuclei can be measured using MAS-NMR probe heads. The Magnetic Resonance Imaging Laboratory is equipped with 360 MHz MR microscope based on a 8.4 T narrow bore SCM and a MRI/MRS system based on a 2 T, 31 cm horizontal bore SCM. Magnetic Resonance Laboratory: Molecular reorientation studies aimed at disclosing tunnelling rotation and structural research of amorphous solids were main topics. Realisation of these projects required a development of our NMR pulse spectrometer and theoretical methods. The spectrometer was put into operation in 1997. Recent development was done in the data acquisition by the introduction of a new A/D converter and a pulse programmer. Tunnelling and reorientations of mixed isotope rotors are currently the most interesting topics. For a given deuteration rate of an ammonium compound it was anticipating that deuteron NMR spectra consist of weighted contributions from the following isotopomers: NH 3 D + , NH 2 D 2 + , NH 3 D + and ND 4 + . Each isotopomer provides a characteristic spectral component due to its mobility. Measurements were performed for a number of partially deuterated samples of (NH 4 ) 2 S 2 O 8 , NH 4 ClO 4 , NH 4 PF 6 , (NH 4 ) 2 ZnCl 4 and (NH 4 ) 2 TeCl 6 in the T = 5-100 K. The spectra of NH 3 D + ions are particularly interesting. A new effect of an isotope ordering was observed. The structural investigations of amorphous solids by NMR

    The theory of the firm is of considerable interest in economics. The standard microeconomic theory of the firm is largely a static model and has thus proved unsatisfactory for addressing inherently dynamic issues such as the growth of economies. In recent years, many have attempted to develop richer models that provide a more accurate representation of firm dynamics due to learning, innovative effort, and the development of organizational infrastructure. The validity of these new, inherently dynamic theories depends on their consistency with the statistical properties of firm growth, e.g. the relationship between growth rates and firm size. Using the Compustat database over the time period 1975-1991, we find: (i) the distribution of annual growth rates for firms with approximately the same sales displays an exponential form with the logarithm of growth rate, and (ii) the fluctuations in the growth rates --- measured by the width of this distribution --- scale as a power law with the firm sales. We place these findings of scaling behavior in the context of conventional economics by considering firm growth dynamics with temporal correlations and also, by considering a hierarchical organization of the departments of a firm.

    Utilizing living organisms' abilities is an effective approach to realize flexible and unconventional computing. One possible bio-inspired computer might be developed from animal collective research by clarifying collective behaviors. Therefore, it is important to reveal how collective animal behaviors emerge. In many studies, individuals departing from the other individualsare generally ignored. Is it not possible that such departing individuals contribute to the organization of such collectives? To investigate the effects of individuals departing from a collective against collective behaviors, we observed and analyzed the behaviors of 40 soldier crabs in four types of experimental arenas. The recorded behaviors demonstrate a temporally changing pattern and the existence of departing individuals. We analyzed the relationship between global activity and cohesion levels and verified the features of departing individuals. The results imply that departing individuals contribute to collective behaviors.
