    2016-07-01

    Pamela experiment has been designed as a cosmic ray observatory at 1 AU, dedicated to the precise and high statistics study of CR fluxes on a three decades energy range, form a few tens MeV up to several hundred GeV region. It is the last step of the 'Russian-Italian Mission' (RIM) program born in 1992 between several Italian and Russian institutes and with the participation of the Royal Institute of Technology of Stockholm (Sweden) and the Siegen University (German). Launched the 16 June 2006 from Baikonur cosmodrome on board of the Resurs-DK1 Russian satellite by a Soyuz rocket in an elliptical (350-610 km) quasi polar orbit (70° inclination) it was activated on 21 June 2006, afterword has been in a continuous data taking mode for ten years. The Pamela program pays particular attention to the study of particles (protons and electrons) and antiparticles (antiprotons and positrons) energy spectra. It also includes search for possible signals of dark matter annihilation, search for primordial antimatter (antihelium), search for new Matter in the Universe (Strangelets?), study of cosmic-ray propagation, solar physics and solar modulation, terrestrial magnetosphere. This program is made possible thanks to the outstanding performance of the instrument, the low energy threshold, the quasi-polar orbit, the 10 years duration of the observation. Protons and helium nuclei are the most abundant components of the cosmic radiation and the precise measurements of their fluxes allow understanding the acceleration and propagation of cosmic rays in the Galaxy. Their spectral shapes cannot be well described by a single power law: at 230-240 GV they exhibit an abrupt spectral hardening. They challenge the current paradigm of cosmic-ray acceleration in supernova remnants followed by diffusive propagation in the Galaxy. Of paramount importance is the discover of the anomalous increase of the positron flux at energies higher that 50 GeV (the so called 'Pamela anomaly'). The review of

    This report documents the authors work as an expert team advising the US Department of Energy on modes of inadvertent intrusion over the next 10,000 years into the Waste Isolation Pilot Project (WIPP) nuclear waste repository. Credible types of potential future accidental intrusion into the WIPP are estimated as a basis for creating warning markers to prevent inadvertent intrusion. A six-step process is used to structure possible scenarios for such intrusion, and it is concluded that the probability of inadvertent intrusion into the WIPP repository over the next ten thousand years lies between one and twenty-five percent. 3 figs., 5 tabs.

    2015-05-01

    The main objective of the Virtual Observatory (VO) is to guarantee an easy and efficient access and analysis of the information hosted in astronomical archives. The Spanish Virtual Observatory (SVO) is a project that was born in 2004 with the goal of promoting and coordinating the VO-related activities at national level. SVO is also the national contact point for the international VO initiatives, in particular the International Virtual Observatory Alliance (IVOA) and the Euro-VO project. The project, led by Centro de Astrobiología (INTA-CSIC), is structured around four major topics: a) VO compliance of astronomical archives, b) VO-science, c) VO- and data mining-tools, and d) Education and outreach. In this paper I will describe the most important results obtained by the Spanish Virtual Observatory in its first ten years of life as well as the future lines of work.

    2014-05-01

    In this presentation we will provide a detailed review of the science highlights of the ENA observations obtained by The Ion Neutral Camera (INCA) on board Cassini. Since the launch of Cassini, INCA has unveiled an invisible world of hot plasma and neutral gas of the two biggest objects of our solar system: the giant magnetosphere of Jupiter and Saturn. Although more than ten years ago, INCA captured the first ENA images of the Jovian system revealing magnetospheric dynamics and an asymmetric Europa neutral gas torus. Approaching Saturn, INCA observed variability of Saturn's magnetospheric activity in response to changes in solar wind dynamic pressure, which was contrary to expectations and current theories. In orbit around Saturn, INCA continued the surprises including the first imaging and global characterization of Titan's exosphere extended out to its gravitational Hill sphere; recurring injections correlating with periodic Saturn Kilometric Radiation (SKR) bursts and magnetic field perturbations; and the discovery of energetic ionospheric outflow. Perhaps most significant, and the focal point of this presentation, is INCA's contribution to the understanding of global magnetospheric particle acceleration and transport, where the combination between ENA imaging and in-situ measurements have demonstrated that transport and acceleration of plasma is likely to occur in a two-step process. First, large-scale injections in the post-midnight sector accelerate and transport plasma in to about 12 RS up to energies of several hundreds of keV. Second, centrifugal interchange acts on the plasma inside of this region and provides further heating and transport in to about 6RS. We discuss this finding in the context of the two fundamental types of injections (or ENA intensifications) that INCA has revealed during its ten years of imaging. The first type is large-scale injections appearing beyond 12 RS in the post-midnight sector that have in many cases had an inward component

    Background and aim Irritable bowel syndrome (IBS) has been associated with high prevalence of psychological and psychiatric disorders. However, the association between IBS and each of its subtypes (diarrhea IBS-D, constipation IBS-C, mixed IBS-M) with anxiety still remains unclear. The purpose of this study was to perform a comparative analysis of the association between anxiety and IBS on a period of ten years. Methods PubMed was searched for studies analyzing IBS and anxiety, published at 10 years interval. The study presents a comparative analysis of the articles that were published between 2003–2005 and 2013–2015, investigating the correlation between anxiety and IBS. Results The initial search identified 220 articles, from which 156 were published between 2013 and 2015, and 64 were published between 2003 and 2005. Of these articles, 15 articles were included in the review. Out of these 15 articles, 10 articles analyzed the correlation between anxiety-depression status in IBS patients using specific questionnaires, 2 articles analyzed genetic variables in IBS, 1 article analyzed serotonin and monoamine oxidase levels in IBS, 1 article analyzed serum levels of IL-1β and IL-10 in IBS, 1 article analyzed somatostatin and vasoactive intestinal peptide levels in IBS. The result was a review of 15 studies that analyzed the association between IBS and anxiety. Conclusions IBS is a heterogeneous disorder caused by numerous psychological, immunological, infectious, endocrine and genetic factors. In recent years, the number of studies concentrating on genetic factors, cytokines and hormones has increased in comparison with the 2003–2005 period, when clinical investigation, using mainly questionnaires was the essential method. Also, the total number of papers investigating anxiety and IBS, considerably increased. The recent studies have confirmed the fact that IBS symptoms are often exacerbated during stressful events and the psychiatric treatment has a positive

    The Swift Gamma Ray Burst Explorer has proven to be an incredible platform for studying the multiwavelength properties of supernova explosions. In its first ten years, Swift has observed over three hundred supernovae. The ultraviolet observations reveal a complex diversity of behavior across supernova types and classes. Even amongst the standard candle type Ia supernovae, ultraviolet observations reveal distinct groups. When the UVOT data is combined with higher redshift optical data, the relative populations of these groups appear to change with redshift. Among core-collapse supernovae, Swift discovered the shock breakout of two supernovae and the Swift data show a diversity in the cooling phase of the shock breakout of supernovae discovered from the ground and promptly followed up with Swift. Swift observations have resulted in an incredible dataset of UV and X-ray data for comparison with high-redshift supernova observations and theoretical models. Swift's supernova program has the potential to dramatically improve our understanding of stellar life and death as well as the history of our universe.

  14. Ten years of Lusi: A review

    2016-04-01

    The Lusi mud eruption has continued uninterrupted for ten years, settling into its current steady-state as a quasi-periodic geyser system. Many past, current, and future studies aim to quantify this system, which increasing evidence suggests is a new-born, tectonic scale hydrothermal system linked to the nearby volcano complex. The debate about whether the triggering of Lusi was a natural event of rather caused by drilling continues, but evidence mounts from the behavior of this system that an anthropogenic cause is highly unlikely. Understanding this system is very important because of its social and economic impact on the surrounding communities, and whether it poses future geohazards in the region from future eruptions. A large effort of infrastructures and constant maintenance activity has been and is being conducted inside the 7km2 mud flooded area. This region is framed by a tall embankment that contains the erupted mud and protects the surrounding settlements. This system is also very important for understanding at a larger scale volcanic hydrothermal systems, and to determine whether this new geothermal resource might be exploited. A large effort is underway from an EU-grant supporting the Lusi-Lab project (CEED, University of Oslo) and an SNF grant supporting the University of Neuchatel to study this system from geochemical, geophysical, and modeling perspectives. This review talk summarizes what is known, what is still unclear, and will revisit the behavior of Lusi since its inception.

    Armenian Virtual Observatory (ArVO, www.aras.am/Arvo/arvo.htm) was created 10 years ago, in 2005, when after the accomplishment of the Digitized First Byurakan Survey (DFBS, www.aras.am/Dfbs/dfbs.html) we had enough resources to run a VO project and contribute in the International Virtual Observatory Alliance (IVOA, www.ivoa.net). ArVO is a project of Byurakan Astrophysical Observatory (BAO) aimed at construction of a modern system for data archiving, extraction, acquisition, reduction, use and publication. ArVO technical and research projects include Global Spectroscopic Database, which is being built based on DFBS. Quick optical identification of radio, IR or X-ray sources will be possible by plotting their positions in the DFBS or other spectroscopic plate and matching all available data. Accomplishment of new projects by combining data is so important that the International Council of Scientific Unions (ICSU) recently created World Data System (WDS, www.icsu-wds.org/) for unifying data coming from all science areas, and BAO has also joined it due to DFBS and ArVO projects.

    2012-06-01

    Ovarian Kaleidoscope database (OKdb) is an online, searchable, public database containing text-based and DNA microarray data to facilitate research by ovarian researchers. Using key words and predetermined categories, users can search ovarian gene information based on gene function, cell type of expression, cellular localization, hormonal regulation, mutant phenotypes, chromosomal location, ligand-receptor relationship, and other criteria, either alone or in combination. For individual genes, users can access more than 10 extensive DNA microarray datasets to interrogate gene expression patterns in a development-specific and cell type-specific manner. All ligand and receptor genes expressed in the ovary are matched to facilitate investigation of paracrine/autocrine signaling. More than 3500 ovarian genes in the database are matched to 185 gene pathways in the Kyoto Encyclopedia of Genes and Genomes to allow for elucidation of gene interactions and relationships. In addition to >400 genes with infertility or subfertility phenotypes when mutated in mice or humans, the OKdb also lists ~50 and ~40 genes associated with polycystic ovarian syndrome and primary ovarian insufficiency, respectively. The expanding OKdb is updated weekly and allows submission of new genes by ovarian researchers to allow instant access to DNA microarray datasets for newly submitted genes. The present database is a virtual community for ovarian researchers and allows users to instantaneously provide their comments for individual gene pages based on an automated Web-discussion system. In the coming years, we will continue to add new features to serve the ovarian research community. PMID:22441797

    2016-01-01

    Background The conventional thyroidectomy is the most frequent surgical procedure for thyroidal surgical disease. From several years were introduced minimally invasive approaches to thyroid surgery. These new procedures improved the incidence of postoperative pain, cosmetic results, patient’s quality of life, postoperative morbidity. The mini invasive video-assisted thyroidectomy (MIVAT) is a minimally invasive procedure that uses a minicervicotomy to treat thyroidal diseases. Methods We present our experience on 497 consecutively treated patients with MIVAT technique. We analyzed the mean age, sex, mean operative time, rate of bleeding, hypocalcemia, transitory and definitive nerve palsy (6 months after the procedure), postoperative pain scale from 0 to 10 at 1 hour and 24 hours after surgery, mean hospital stay. Results The indications to treat were related to preoperative diagnosis: 182 THYR 6, 184 THYR 3–4, 27 plummer, 24 basedow, 28 toxic goiter, 52 goiter. On 497 cases we have reported 1 case of bleeding (0,2%), 12 (2,4%) cases of transitory nerve palsy and 4 (0,8%) definitive nerve palsy. The rate of serologic hypocalcemia was 24.9% (124 cases) and clinical in 7.2% (36 cases); 1 case of hypoparathyroidism (0.2%). Conclusions The MIVAT is a safe approach to surgical thyroid disease, the cost are similar to CT as the adverse events. The minicervicotomy is really a minimally invasive tissue dissection.

    2005-01-01

    Ten years ago, our 1995 paper Ten Commandments of Formal Methods suggested some guidelines to help ensure the success of a formal methods project. It proposed ten important requirements (or "commandments") for formal developers to consider and follow, based on our knowledge of several industrial application success stories, most of which have been reported in more detail in two books. The paper was surprisingly popular, is still widely referenced, and used as required reading in a number of formal methods courses. However, not all have agreed with some of our commandments, feeling that they may not be valid in the long-term. We re-examine the original commandments ten years on, and consider their validity in the light of a further decade of industrial best practice and experiences.

    The first ten years of the National Institute on Drug Abuse’s Clinical Trials Network (CTN) yielded a wealth of data on the effectiveness of a number of behavioral, pharmacologic, and combined approaches in community based settings. As an introduction to this Special Issue on the CTN, we summarize some of the methodological contributions and lessons learned from the behavioral trials conducted during its first ten years, including the capacity and enormous potential of this national research infrastructure; contributions to the methodology of effectiveness research; new insights from secondary analyses; the extent to which approaches with strong evidence bases, such as contingency management, extend their effectiveness to real world clinical settings; new data on ‘standard treatment’ as actually practiced in community programs, the extent to which retention remains a major issue in the field; important data on the safety of specific behavioral therapies for addiction; and heightened the importance of continued sustained attention to bridging the gap between treatment and research. Possible areas of focus for the CTN’s future include defining common outcome measures to be used in treatment outcome studies for illicit drugs; incorporating performance indicators and measures of clinical significance; conducting comparative outcome studies; contributing to the understanding of effective treatments of comorbidity; reaching underserved populations; building implementation science; understanding long-term outcomes of current treatments and sustaining treatment effects; and conducting future trials more efficiently.

    1995-12-31

    The Port Nickel facility in Braithwaite, Louisiana, is known for pioneering hydrometallurgical processes for the separation and recovery of nickel, cobalt and copper. Ten years ago, in 1985, a new CRI-MET process for the recovery of molybdenum, vanadium, nickel, cobalt and alumina from spent catalysts was developed and implemented. Spent catalysts from the petroleum industry constitute the majority of feed. These are not only a valuable source of metals, but due to EPA regulations are frequently classified as hazardous under RCRA. Molybdenum and vanadium are selectively leached in an oxidative hydrothermal step. Alumina is then extracted in a Caustic digestive leach. The unique technology produces four primary commercial products: molybdenum trioxide, vanadium oxide, aluminum trihydrate and nickel-cobalt concentrate. This paper discusses the process, modifications during ten years of operation, and the relationship of these modifications to the future of the catalyst recycling business.

    The Nutrition Education and Research Program at the University of Nevada School of Medicine was awarded two separate NIH/NCI R25 cancer education grants over a ten-year period. With this support, a four-year longitudinal nutrition curriculum was implemented, including the required 20-hour freshman Medical Nutrition Course, junior and senior nutrition electives, and a senior assignment in nutrition and cancer during the rural rotation with faculty preceptors. Funding has also supported nutrition integration into the basic science courses, patient care courses, and specialty clerkships. A unique nutrition fellowship for medical students who specialize in nutrition during their four years of training and graduate with special Qualifications in Nutrition (SQIN) has also been instituted. The curriculum reflects a longitudinal, interdisciplinary, but flexible, integration of nutrition into an already crowded medical school education.

    For a large territorial state like Bavaria only a decentralised cancer registration structure promises successful results: in the form of regional clinical cancer registries and--using the clinical registration as a base--one population-based registry. After ten years of epidemiological cancer registration in Bavaria it can now be shown that the chosen registration concept has proved itself. Currently the completeness of cancer notifications exceeded the international recommended threshold of 90%. A largely complete data stock is available for the years of diagnosis from 2004 to 2005. The task sharing between clinical and population-based cancer registries avoids double registration of data. Both types of registries are supporting physicians and hospitals with a wide palette of services. Together they enable transparency of cancer occurrence as well as transparency of health care for tumour patients. PMID:19326333

    Background/Aims. Peritoneal dialysis is a successful renal replacement therapy (RRT) for old and dependent patients. We evaluated the clinical outcomes of an assisted peritoneal dialysis (aPD) program developed in a Portuguese center. Methods. Retrospective study based on 200 adult incident patients admitted during ten years to a PD program. We included all 17 patients who were under aPD and analysed various parameters, including complications with the technique, hospitalizations, and patient and technique survival. Results. The global peritonitis rate was lower in helped than in nonhelped patients: 0.4 versus 0.59 episodes/patient/year. The global hospitalization rate was higher in helped than in nonhelped patients: 0.67 versus 0.45 episodes/patient/year (p = NS). Technique survival in helped patients versus nonhelped patients was 92.3%, 92.3%, 83.1%, and 72.7% versus 91.9%, 81.7%, and 72.1%, and 68.3%, at 1, 2, 3, and 4 years, respectively (p = NS), and patient survival in helped patients versus nonhelped patients was 93.3%, 93.3%, 93.3%, and 74.7% versus 95.9% 93.7%, 89%, and 82% at 1, 2, 3, and 4 years, respectively (p = NS). Conclusions. aPD offers an opportune, reliable, and effective home care alternative for patients with no other RRT options. PMID:26600950

    Superfund celebrated its tenth anniversary in December 1990. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) - popularly known as Superfund - was passed into law in December 1980 in the wake of such incidents as Love Canal and the Valley of the Drums. The program was designed to clean up uncontrolled hazardous waste sites and, during the past ten years, thousands of actions have been taken to protect human health and the environment from the hazards posed by those sites. EPA believes that goal is best met by its strategy: make sites safer - control immediate threats; enforce aggressively; make sites cleaner - worst problems at worst sites first; bring new technology to bear on the problem.

  18. Television programming and disability: a ten year span.

    1980-01-01

    Television programming covering disability over a ten year span, 1967-68 and 1977-78, was studied to determine similarities and differences. Variables identified for comparisons included network, program type, disability, time slot, and length of programming. The largest frequency of programs occurred on NBC in 1968. However, in 1978 the largest frequency occurred on the Public Broadcasting System. This can be partially explained by the increased numbers of programs on PBS overall and their traditional concern with public interest and service programming. The commercial networks historically have been in the business of entertaining and portray disability more so in that fashion. Movies head the list in 1968. However, in 1978, dramatic series and children's programming head the list followed by news documentaries and telethon. Paraplegia was the most frequent disability portrayed in 1968 followed by mental illness, drug addiction and emotional disability. In 1978 mental illness headed the list followed by alcoholism, emotional disability and physically handicapped. Paraplegia in 1968 can be accounted for by the program "Ironside" that featured a paraplegic detective. Mental illness and emotional disturbance seem to be consistent targets over the decade for popular programming in prime time. PMID:6450185

    A comparison is made between compilations of times of origination and extinction of fossil marine animal families published in 1982 and 1992. As a result of ten years of library research, half of the information in the compendia has changed: families have been added and deleted, low-resolution stratigraphic data been improved, and intervals of origination and extinction have been altered. Despite these changes, apparent macroevolutionary patterns for the entire marine fauna have remained constant. Diversity curves compiled from the two data bases are very similar, with a goodness-of-fit of 99%; the principal difference is that the 1992 curve averages 13% higher than the older curve. Both numbers and percentages of origination and extinction also match well, with fits ranging from 83% to 95%. All major events of radiation and extinction are identical. Therefore, errors in large paleontological data bases and arbitrariness of included taxa are not necessarily impediments to the analysis of pattern in the fossil record, so long as the data are sufficiently numerous.

    The widely held constructivist view of learning advocates student engagement via interactivity. Within the physics education research community, several specific interactive strategies have been developed to enhance conceptual understanding. One such strategy, the Interactive Lecture Demonstration (ILD) is designed for large lecture classes and, if measured using specific conceptual surveys, is purported to provide learning gains of up to 80%. This paper reports on learning gains for two different Projects over ten years. In Project 1, the ILDs were implemented from 1999 to 2001 with students who had successfully completed senior high school physics. The learning gains for students not exposed to the ILDs were in the range 13% to 16% while those for students exposed to the ILDs was 31% to 50%. In Project 2, the ILDs were implemented from 2007 to 2009 with students who had not studied senior high school physics. Since the use of ILDs in Project 1 had produced positive results, ethical considerations dictated that all students be exposed to ILDs. The learning gains were from 28% to 42%. On the one hand it is pleasing to note that there is an increase in learning gains, yet on the other, we note that the gains are nowhere near the claimed 80%. This paper also reports on teacher experiences of using the ILDs, in Project 2.

  1. Ten year lifetime orbits about the planet Mars

    Bain, Rodney Donald

    1988-06-01

    A spacecraft designed for a mapping or photographic planetary mission will need to penetrate the atmosphere of Mars at its upper levels to gather the required data. The problem investigated is the determination of an envelope (called the Critical Envelope) about the planet Mars with the criteria of non-impact with the Martian surface for at least ten earth-years. The major constituent of the envelope involves the determination of the minimum value of the Periapsis Altitude of such an envelope. The purpose of this non-impact (quarantine) condition is to insure non-introduction of foreign materials into the Martian environment. This quarantine condition requires the determination of long-term perturbative effects upon the envelope. The problem was modeled as an astrodynamic perturbation problem affected by atmospheric drag (modeled as an exponential atmosphere) and aspherical gravitational effects, along with the geometric oblateness of the planet. In order to determine the gravity effects three different models were employed (2 x 0, 4 x 4, and 8 x 8). To reduce the configuration space, the Mean Anomaly and the Argument of Periapsis are set to zero. The number of orbits (2,263) investigated indicated that the Periapsis Altitude should be set at 441 km or above. Orbital data included the ranges of eccentricities from .01 to .1, variations of the inclination from 0.5 degrees to 85.5 degrees, and the Longitude of the Ascending Node varying from 0 to 360 degrees.

    The Holistic System of Care for Native Americans in an Urban Environment is a community-focused intervention that provides behavioral health care, promotes health, and prevents disease. This approach is based on a community strategic planning process that honored Native American culture and relationships. Substance abuse, mental illness, homelessness, poverty, crime, physical illness, and violence are symptoms of historical trauma, family dysfunction, and spiritual imbalance. The holistic model links treatment, prevention, and recovery. The link between prevention and treatment is early intervention. Peer support is the link between treatment and recovery. Recovering individuals serve as role models linking recovery to prevention. Culture and spirituality build a strong and resilient foundation for recovery. This article documents the effectiveness of the holistic model over a ten-year period that it has been implemented at the Family & Child Guidance Clinic of the Native American Health Center in the San Francisco Bay Area. The holistic model has produced statistically significant reductions in substance abuse among adult Native American women, men, reentry, and homeless populations; reductions in substance abuse among Native American adolescents; reductions in HIV/AIDS high-risk behavior among Native American men, women, and adolescents; and decreases in acting out behavior among Native American severely emotionally disturbed children.

  3. Ten Years of Real-Time Earthquake Loss Alerts

    2013-12-01

    The priorities of the most important parameters of an earthquake disaster are: Number of fatalities, number of injured, mean damage as a function of settlement, expected intensity of shaking at critical facilities. The requirements to calculate these parameters in real time are: 1) Availability of reliable earthquake source parameters within minutes. 2) Capability of calculating expected intensities of strong ground shaking. 3) Data sets on population distribution and conditions of building stock as a function of settlements. 4) Data on locations of critical facilities. 5) Verified methods of calculating damage and losses. 6) Personnel available on a 24/7 basis to perform and review these calculations. There are three services available that distribute information about the likely consequences of earthquakes within about half an hour of the event. Two of these calculate losses, one gives only general information. Although, much progress has been made during the last ten years improving the data sets and the calculating methods, much remains to be done. The data sets are only first order approximations and the methods bare refinement. Nevertheless, the quantitative loss estimates after damaging earthquakes in real time are generally correct in the sense that they allow distinguishing disastrous from inconsequential events.

    It has been nearly ten years since the First State of the Carbon Cycle Report (SOCCR-1) was published in 2007. Much has changed in the intervening years, but much has remained the same. In anticipation of a Second State of the Carbon Cycle Report (SOCCR-2), we, the members of the SOCCR-1 Coordinating Team, felt that a perspective from the first SOCCR and reflection on changes in the state of carbon cycle science and policy in the intervening years would be appropriate. The purpose of SOCCR-1 was to provide "…a synthesis and integration of the current knowledge of the North American carbon budget and its context within the global carbon cycle [i]n a format useful to decision makers." Being "useful to decision makers" was a guiding theme with three stakeholder workshops an integral part of the process. Drafting and revision of SOCCR-1 took place between 2005 and early 2007; the report's carbon budget was for circa 2003. In 2003, North America's fossil-fuel CO2 emissions were approximately 27% of global emissions. Nearly 85% of North American emissions were from the US, still at that time the world's largest emitter of fossil-fuel CO2. China's annual CO2 emissions exceeded those of the US for the first time while SOCCR-1 was being written. Today global CO2 emissions are dominated by emissions from China (28% in 2013), with US emissions only 14% of global emissions. Emissions from the US and North America have actually declined by approximately 10% since 2003 while emissions from China have doubled. Based on inventories of terrestrial carbon stocks, SOCCR-1 estimated that circa 2003 North American vegetation removed and stored a net 500 Mt C y-1 (±50%) from the atmosphere. A more recent synthesis incorporating additional estimates from atmospheric inversions and terrestrial biosphere modeling estimated the North American land sink for the decade of 2000-2009 at 350-470 Mt C y-1, with a slightly greater uncertainty due to the wider range of estimates from the

    The Lightning Imaging Sensor (LIS) is a space based instrument used to detect the distribution and variability of total lightning (cloud-to-cloud, intracloud, and cloud-to-ground lightning) that occurs in the tropical regions of the globe. LIS was launched in November 1997 aboard NASA’s Tropical Rainfall Measuring Mission (TRMM). The LIS sensor contains a staring imager which is optimized to locate and detect lightning with storm-scale resolution of 3-6 km (3 at nadir, 6 at limb) over a large region (550-550 km) of the Earth's surface. The field of view (FOV) is sufficient to observe a point on the Earth or a cloud for 80 seconds, adequate to estimate the flashing rate of many storms. The instrument records the time of occurrence of a lightning event, measures the radiant energy, and estimates the location. The excellent performance of LIS has lead to numerous scientific discoveries such as: The global lightning flash rate is on the order of 40 flashes per second as compared to the commonly accepted value of 100, an estimate that dates back to 1925. Seventy percent of all lightning activity occurs in the tropics, with the global distribution dominated by the summertime lightning activity over the N. Hemisphere land masses. A new understanding on the interplay among the intensification of updraft, lightning bursts, and the onset of severe weather lead to establishment of a validation campaign that further explored relationships between lightning and severe weather. Findings to date indicate that high flash rate storms have a high probability of becoming severe. A ten year global lightning data archive has been developed from the Lightning Imaging Sensor. This archive is maintained at the Global Hydrology Resource Center (GHRC) in Huntsville Alabama, one of NASA’s Earth science data centers, managed by the Information Technology and Systems Center of UAHuntsville. This is the most comprehensive global lightning data archive ever produced and is noteworthy for its

  6. Ten-Year Retrospective on the Pinatubo Eruption

    2001-12-01

    The 1991-92 eruption of Pinatubo Volcano, Philippines was a signal event in the annals of volcanology. For the first time, modern monitoring captured the pre-, syn-, and post-eruption signatures of a sulfur-rich, plinian, caldera-forming eruption. Approximately 5 km3 of magma was erupted, of which slightly more than half became pyroclastic flows, and the balance became tephra fall. Only a negligible percentage of the magma fed early and final-stage lava domes. Ten years later, more than half of the debris on Pinatubo's slopes has been washed by lahars and sediment-laden streamflow into the surrounding lowlands, adding to Pinatubo's broad alluvial fans. Other papers in this symposium will give details of the magma, volatiles, eruption dynamics, lahars, atmospheric effects, and other features of the eruption. Here, we reflect on just four lessons. First, the magma of a long-plugged volcano may be saturated with respect to water and other volatiles even at depth, and, when disturbed by regional strain or other change, can rise quickly. Second, up until just before the eruption itself, only the geologic record foretold of how large it would be. Third, because few observatories will monitor dormant volcanoes and few residents will heed long-range warnings, public safety will hinge on a short, urgent campaign of warning and education. Videos, simple alert schemes, and a willingness of both scientists and public officials to move decisively despite uncertainty are essential to win cooperation from a skeptical public. Fourth, post-eruption hydrologic hazards can equal or exceed those of an eruption itself.

  7. Looking back at a US desalting forecast - ten years later

    Rothermel, T.W.

    1982-01-01

    Forecasts made a decade ago of US desalting capacity by 1980 achieved mixed success when compared to the most recent Desalting Plants Inventory. Projections of national brackish water were right on the button. The forecast of new brackish capacity for 1965 to 1980 was 105 Mgd. The Inventory indicates that 106 Mgd was installed. Seawater desalting forecasts, however, were just as overly optimistic as the projected costs upon which they were based: 191 Mgd was forecasted for 1965 to 1980; only 10 Mgd actually went on-stream. Forecasts were also made of desalting waste-waters for reuse. The recent emergence of this desalting application was reflected in a forecast of 5 Mgd, which was still less than the 23 Mgd found in the Inventory. These forecasts were made with a dynamic simulation model of the water demand and supply situations in 100 subregions of the United States. This computerized model was built under the sponsorship of the US Department of the Interior to provide a basis for estimating the benefits of federally sponsored desalting research. The model also promises valuable planning insights for regulatory and research programs in broader water resources activities. The most recent Desalting Plants Inventory is certainly unfair to forecasters by systematically tracking actual installations of desalting capacity. This article compares data in the Inventory to forecasts developed over ten years ago. That work was sponsored by the former Office of Saline Water (OSW) and its successor, the Office of Water Research and Technology (OWRT). These forecasts were created from a simulation model of the national water situation. 5 references, 1 figure, 3 tables.

    Precise timing of millisecond binary pulsars has been started at Kalyazin radio astronomical observatory since 1995. (Tver' region, Russia). Binary pulsars: J0613-02, J1020+10, J1640+22, J1643-12, J1713+07, J2145-07 and isolated millisecond pulsar B1937+21 have been included among the Kalayazin Pulsar Timing Array (KPTA). The Backer's pulsar B1937+21 is being monitored at Kalyazin observatory (0.6 GHz) and Kashima space research centre of the National Institute of Communication Technology (NICT, Japan) (2.2 GHz) simultaneously from 1996, as well. .At Kalyazin pulsars are observed at 0.6 GHz by a full steerable 64-m dish radio telescope RT-64 of the Special Research Bureau of the Moscow Power Engineering Institute. Filter-bank receiver of PRAO Lebedev Physical Institute is used for observations in two circular polarizations by 80 channels per each. Bandwidth per channel is 40 kHz, so total band is 3.2 MHz and time resolution is about 10 μs per channel. Now a perfect data base of pulses Time of Arrival (TOA) are collected with refer to the Solar system barycenter for about 10 years period. Main aim is: a) to study Pulsar Time and to establish a long-term standard of time based on pulsars ensemble as space long life clock alternative to atomic standards; b) to detect gravitational waves extremely low frequency belong to the Gravity Wave Background - GWB. After ten years monitoring of B1937+21 its timing noise is looking as "white phase noise" with RMS about 1.8 μs.( Fractional instability is about 6.10^-15). After these data and timing results of binary pulsar J1640+22 gravitational natural GWB upper limit should be reduced till to less than Ω[g]h^2 <10^-7-10^ -9 . Secular changes of DM toward millisecond pulsar B1937+21 was revealed after long time two frequency timing observations (Kalyazin -0,6 and Kashima -2.3).

    Giant prolactinomas are rare pituitary tumours of which management can be a challenge. A 28-year-old man presented with headaches, visual impairment and behavioural changes. Clinically, the patient was found to have hypogonadism and bitemporal hemianopsia. A MRI demonstrated a pituitary tumour 76 mm in diameter and blood tests revealed a serum prolactin of 158,700 µU/mL (reference range 58-254). Initially, a craniotomy was performed. Immunohistochemistry of the tumour identified a prolactinoma with a high proliferative index and the patient was started on treatment with a dopamine agonist. A year later, neurological symptoms worsened due to regrowth of the lesion's cystic component, and so further surgery was performed. After 10 years of treatment with dopamine agonists, the prolactin levels decreased by 96.8%, there was an effective reduction in tumour size, and the neurological signs and symptoms resolved.

    The Asklepios study started 10 years ago when 2,500 subjects were screened between 2002 and 2004. And all of the 90+ publications we have for the moment are from those cross-sectional data. This is called round 1. Since 2011, in round 2, all of those patients have started to come back for a 10-year follow-up. At this moment, approximately 1,750 of those patients have been seen. The patients were followed by general practitioners (GP), and the GP again provided the information about what has happened with the medical status in the past 10 years including drug therapy: not only the drugs that they are taking at the moment were evaluated, but, because patients often use many drugs, the chronicles of drugs for major risk factors, for hypertension, lipids, contraceptives and more. Then, patients come to the study center where the same cluster of examinations are undertaken by one single doctor, Prof. Ernst R. Rietzschel and one study nurse, just like 10 years ago. Again, using a single observer at the two time frames has kept the methodology very strict. PMID:26587452

    Background: Anogenital warts are a common cause of morbidity affecting mainly the productive age group of the economy. Paucity of data in Nigeria necessitated this study. Materials and Methods: The pathology records of anogenital warts diagnosed in the Department of Pathology, Ahmadu Bello University Zaria between 1st January 2000 and 31st December 2009 were reviewed. Results: A total of 68 warts were diagnosed within the study period with anogenital warts constituting 39.7%. Majority of cases (62%) were in the 20-39 years age group (range: 5–50 years) and vulva was the most common site affected. Conclusion: Genital warts are common in our environment, biopsy of suspicious lesions is recommended for diagnostic yield. PMID:24403708

    A 1999 white paper predicted a revolution in lighting technology by extrapolating the 30-year history of red LEDs to estimate the performance and cost for white LED lamps for the following two decades. In this Expert Opinion, Haitz and Tsao discuss the hits and misses of the 1999 predictions and analyze the necessary and sufficient conditions for this revolution to succeed. The graph on the cover updates the flux and cost performance for red and white LEDs and confirms that these 1999 predictions still hold. The global wave of investments in R&D and manufacturing infrastructure triggered by the 1999 graph will continue, thus leaving little doubt that this disruptive technology will dominate the lighting industry, not this year or the next, but over the next two decades.

    A 10-year review of the ''Energy Crisis'' years focuses primarily on the issue of energy conservation. The paper stresses the changing definition of the energy crisis from oil import insecurity to economic insecurity, and explores in each energy-consuming sector of the economy the major trends of energy demand over the last decade and the special impact of our changing energy climate on the poor. The report concludes that the US has made significant progress towards adjusting to a new era of expensive energy, but that progress is small relative to the potential for cost-effective energy conservation investments and energy savings. The major challenge still involves stimulating the marketplace to capture these savings through investments rather than through reductions in our standard of living or economic growth. The need remains to assist those who lack the funds for such investments so they can reduce the financial drain of energy waste. 31 tables.

    A brief description of the history of Cancer Control in Japan was presented for the first time. The establishment of the National Cancer Center and Comprehensive 10-year Strategy for Cancer Control Program, which has been implemented for 30 years, is most important. In response to the concerns raised by cancer patients, their families, and lay people, such as elimination of disparity arising from where they live or which hospital they attend, and asymmetrical cancer information, the Cancer Control Act was established in 2006 and executed in 2007. The Basic Plan to Promote Cancer Control Programs was started in 2007 as a 10-year plan. Hospitals that specialize in cancer treatment, nearly 400 in total, were appointed all over Japan. Hospitals that specialize in pediatric cancer were also appointed all over Japan. Cancer education for children and special issues, including employment of cancer patients, were stressed. Since the establishment of the Cancer Control Act, the Cancer Control Strategy in this country has been achieved remarkably as a frame. Henceforth, all items should be elucidated by giving importance to the opinion of patients, their families, and lay people. PMID:27628541

    Cardiovascular disease (CVD) is responsible for more than half of all deaths in the European region. The aim of the study was to compare body composition, blood pressure, total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C), family history, activity behaviors, and the 10-year risk of having a heart attack between 166 university students (21.62 ± 2.59 yrs) from Utah (USA) and 198 students (22.11 ± 2.51 yrs) from Hungary. Ninety-two percent of the Hungarian students and 100% of the Utah students had an estimated 10-year Framingham risk score of 1% or less. The high prevalence of low risk was primarily due to the young age of study participants, healthy body composition and non-smoking behavior. Hungarians who had higher 10-year risk of heart attack had significantly higher waist hip ratio (WHR), TC, diastolic blood pressure (DBP) and were smokers compared to those Hungarians with lower risk. The self-reported physical activity levels between the two groups of students were not different. In conclusion the young men and women who participated in this study were, for the most part healthy; however the smoking habits and the lower physical activity of the Hungarian students likely elevated their risk of CVD.

    In the 10 years since lunar laser ranging became a reality the need to analyze the observations has motivated improvements in several aspects of the mathematical model of earth-moon dynamics. Application of the data to improved estimates of the physical parameters of the earth-moon system has yielded significant astronomical, selenophysical, geophysical, and cosmological results. The scientific impact, both in improved theories and in numerical applications, is surveyed. The underlying physics and major difficulties are discussed, as well as the scientific results.

    In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by

  9. Dynamic shear jamming in granular suspensions

    Jamming by shear allows a frictional granular packing to transition from an unjammed state into a jammed state while keeping the system volume and average packing fraction constant. Shear jamming of dry granular media can occur quasi-statically, but boundaries are crucial to confine the material. We perform experiments in aqueous starch suspension where we apply shear using a rheometer with a large volume (400 ml) cylindrical Couette cell. In our suspensions the packing fraction is sufficiently low that quasi-static deformation does not induce a shear jammed state. Applying a shock-like deformation however, will turn the suspension into a jammed solid. A fully jammed state is reached within tens of microseconds, and can be sustained for at least several seconds. High speed imaging of the initial process reveals a jamming front propagating radially outward through the suspension, while the suspension near the outer boundary remains quiescent. This indicates that granular suspensions can be shear jammed without the need of confining solid boundaries. Instead, confinement is most likely provided by the dynamics in the front region.

    Over the last 10 years we have registered in our district (about 500,000 inhabitants) 36 cases of fatal methadone poisoning, involving both patients on treatment and naive subjects: this is a significant increase of deaths due to methadone use, misuse or abuse compared with previous years. Twenty-four patients (66.7%) were on methadone maintenance programs for heroin detoxification, while 12 (33.3%) were taking the drug without a medical prescription. The average blood concentration of methadone in patients undergoing a maintenance program was 1.06 mg/L (0.21-3.37 mg/L), against 0.79 mg/L (0.2-3.15 mg/L) in those taking the non-prescribed drug. Since 111 heroin-related deaths were recorded in our district in the same period, the fact that there appear to be many methadone deaths (about a third of heroin-related deaths) cannot be overlooked. The aim of this work is to understand the possible reasons for such a large number of methadone-related deaths. On this subject, we have noticed that risks associated with methadone intake are often underestimated by clinicians prescribing the drug: sometimes methadone is prescribed without taking into account patient's tolerance to opiates, and a large number of subjects enrolled in methadone maintenance programs in Italy, have also been given take-home doses, thus increasing the risk of abuse and diversion.

    Introduction: To study the long-term complications of tympanostomy tube insertion in young children 10 years after surgery. Materials and Methods: In September 2011, the medical records of all patients who had undergone myringotomy with tympanostomy tube insertion between February 2000 and March 2001 at the two general hospitals of Isfahan University of Medical Sciences were studied. Of the 98 patients who fulfilled the inclusion criteria, 82 patients agreed to participate and were enrolled in the study. The complications of the operation were evaluated in these patients. Results: Of the 164 ears that were operated on, myringosclerosis was found in 17.1%, atrophy of the tympanic membrane in 1.2%, permanent perforation of the tympanic membrane in 0.6% and tympanic membrane atelectasis in 0.6%. None of the patients developed cholesteatoma as a complication of tympanostomy tube insertion. Conclusion: Considering the low risk of serious complications after 10 years, tympanostomy tube insertion is a safe and effective treatment option in the treatment of otitis media with effusion.

    In Bucaramanga, Colombia, dengue haemorrhagic fever (DHF) has become endemo-epidemic since 1992. A cross-sectional study covering a period of 10 years (February, 1992 to February, 2002) was undertaken in children under 13 years of age hospitalized at the University Hospital. Observations were recorded on the clinical features, laboratory tests and the natural development of the disease. A total of 763 patients were examined, of whom 617 were classified as having DHF according to the WHO criteria (9.1% Grade I, 61.5% Grade II, 21.7% Grade III and 7.5% Grade IV). One hundred forty six patients could not be classified. The highest incidence took place in 1997, 1998 and 2001. Seventy four per cent of patients came from the metropolitan area of Bucaramanga; 48% were males; 0.3%, newborns; 11.8%, infants; 23%, pre-school children, and 64.9%, school children. The most important clinical features were fever and haemorrhagic manifestations (100%); vomiting (60%); abdominal pain (57%); headache (50%); osteomyalgia (40.8%); hepatomegaly (33%), and macular rash (29%). Among the haemorrhagic manifestations we found petechiae (56%); positive tourniquet test (35%); gastrointestinal bleeding (34%), and epistaxis (32%). Serous effusion was found in 17.7% of cases. Alarm signs of shock were found in 29%. Fifty two per cent had leucopenia and 37.3% atypic lymphocytes. Among other unusual manifestations were hepatitis, encephalopathy, alithiasic cholecystitis, acute renal failure, haemophagocytic syndrome and coinfections. Of the 617 cases, 12 died (1.5%).

    Context Borderline personality disorder (BPD) is traditionally considered chronic and intractable. Objective To compare the course of BPD’s psychopathology and social function with that of other personality disorders and with major depressive disorder (MDD) over 10 years. Design A collaborative study of treatment-seeking, 18-to 45-year-old patients followed up with standardized, reliable, and repeated measures of diagnostic remission and relapse and of both global social functioning and subtypes of social functioning. Setting Nineteen clinical settings (hospital and outpatient) in 4 northeastern US cities. Participants Three study groups, including 175 patients with BPD, 312 with cluster C personality disorders, and 95 with MDD but no personality disorder. Main Outcome Measures The Diagnostic Interview for DSM-IV Personality Disorders and its follow-along version (the Diagnostic Interview for DSM-IV Personality Disorders–Follow-Along Version) were used to diagnose personality disorders and assess changes in them. The Structured Clinical Interview for DSM-IV Axis I Disorders and the Longitudinal Interval Follow-up Evaluation were used to diagnose MDD and assess changes in MDD and in social function. Results Eighty-five percent of patients with BPD remitted. Remission of BPD was slower than for MDD (P<.001) and minimally slower than for other personality disorders (P<.03). Twelve percent of patients with BPD relapsed, a rate less frequent and slower than for patients with MDD (P<.001) and other personality disorders (P=.008). All BPD criteria declined at similar rates. Social function scores showed severe impairment with only modest albeit statistically significant improvement; patients with BPD remained persistently more dysfunctional than the other 2 groups (P<.001). Reductions in criteria predicted subsequent improvements in DSM-IV Axis V Global Assessment of Functioning scores (P<.001). Conclusions The 10-year course of BPD is characterized by high rates of

    Objective Living a purposeful life is associated with better mental and physical health, including longevity. Accumulating evidence shows that these associations might be explained by the association between life purpose and regulation of physiological systems involved in the stress response. The aim of this study was to investigate the prospective associations between life purpose and allostatic load over a 10-year period. Methods Analyses were conducted using data from the Midlife in the United States (MIDUS) survey. Assessment of life purpose, psychological covariates and demographics were obtained at baseline, while biomarkers of allostatic load were assessed at the 10-year follow-up. Results We found that greater life purpose predicted lower levels of allostatic load at follow-up, even when controlling for other aspects of psychological well-being potentially associated with allostatic load. Further, life purpose was also a strong predictor of individual differences in self-health locus of control—i.e., beliefs about how much influence individuals can exert on their own health—which, in turn, partially mediated the association between purpose and allostatic load. Although life purpose was also negatively linked to other-health locus of control —i.e., the extent to which individuals believe their health is controlled by others/chance —this association did not mediate the impact of life purpose on allostatic load. Conclusion The current study provides the first empirical evidence for the long-term physiological correlates of life purpose and supports the hypothesis that self-health locus of control acts as one proximal psychological mechanism through which life purpose may be linked to positive biological outcomes.

    PubMed

    Liguori, A L

    1991-01-01

    AIDS and the economic crisis in Mexico are threatening the epidemiologic transition in which infectious diseases ceased to be the only major cause of death and chronic degenerative diseases began to account for a growing proportion of deaths. Many factors combined to produce the sexual, gay, and women's liberation movements beginning in the 1970s. At the beginning of the feminist movement, women proposed different kinds of interpersonal relations both between women and with men. Women together realized their rights to control their own bodies, to sexual enjoyment, to abortion, and to free themselves of feelings of shame and guilt. The weight of moral pressures was lessened and the personal desires of the woman assumed a greater role in selection of sexual partners. Conservative forces grew stronger in the 1980s, and the proliferation of sexually transmitted diseases began to imperil the sexual revolution. But these setbacks were minor compared to AIDS. Now, 10 years after its appearance, it is clear that AIDS is not limited to homosexual men. The number of cases in Mexico increased from none 10 years ago to some 10,000 estimated cases reported and unreported today. 1/6 of the cases are in women. Many women and heterosexuals felt immune from AIDS in the beginning, and some still do, but many more have become aware of the danger. Women now fear contracting AIDS, but they also fear confronting their partners to suggest that they use condoms. Denial may play a role, but deeply rooted cultural factors that women may recognize but fee powerless to change may also be at play. Many women over 30 have difficulty taking the initiative in sexual matters. They are embarrassed to buy condoms and even more embarrassed to propose their use. They imagine that men will consider them "loose" if they carry condoms. Mexican women are poorly prepared to tell their men explicitly what they want sexually, and Mexican men are also poorly equipped to ask what women want, accustomed as they

    ABSTRACT Ovarian Kaleidoscope database (OKdb) is an online, searchable, public database containing text-based and DNA microarray data to facilitate research by ovarian researchers. Using key words and predetermined categories, users can search ovarian gene information based on gene function, cell type of expression, cellular localization, hormonal regulation, mutant phenotypes, chromosomal location, ligand-receptor relationship, and other criteria, either alone or in combination. For individual genes, users can access more than 10 extensive DNA microarray datasets to interrogate gene expression patterns in a development-specific and cell type-specific manner. All ligand and receptor genes expressed in the ovary are matched to facilitate investigation of paracrine/autocrine signaling. More than 3500 ovarian genes in the database are matched to 185 gene pathways in the Kyoto Encyclopedia of Genes and Genomes to allow for elucidation of gene interactions and relationships. In addition to >400 genes with infertility or subfertility phenotypes when mutated in mice or humans, the OKdb also lists ∼50 and ∼40 genes associated with polycystic ovarian syndrome and primary ovarian insufficiency, respectively. The expanding OKdb is updated weekly and allows submission of new genes by ovarian researchers to allow instant access to DNA microarray datasets for newly submitted genes. The present database is a virtual community for ovarian researchers and allows users to instantaneously provide their comments for individual gene pages based on an automated Web-discussion system. In the coming years, we will continue to add new features to serve the ovarian research community. PMID:22441797

    2016-01-01

    Introduction Cerebrospinal Fluid (CFF) fistulae are repaired endoscopically with varying degrees of success around the world. Large series are still uncommon, and the results varied primarily because of the different techniques by different surgeons and also because of a variation in the patient profile in each series, for example, many series deal primarily with traumatic CSF leaks where the defects are larger and outcomes poorer. Aim To analyse the surgical outcomes of Endoscopic CSF rhinorrhea closure. Materials and Methods This is a series of 34 cases operated upon primarily by one surgeon in two different centres over a period of 10 years. Results Of the 34 cases, 76% of the patients were women. Among the patients only 20.6% patients had a history of trauma preceding the CSF leak. The most common site of leak was in the fovea ethmoidalis in 19 (55.8%) followed by 10 (29.4%) in the cribriform plate. An overlay technique of placing the multiple layers of fascia and mucosa was used in 26 (76.5%) patients and underlay technique in the remaining. Postoperative lumbar drain was used in all patients. Conclusion Based on the treatment outcome of the 34 patients, it can be concluded that the success rate of a single endoscopic procedure in our experience is 97% and 100% following the second. Endoscopic approach for closure of CSF leak is safe with minimal complications and little morbidity. PMID:27656471

    The purpose of this study was to evaluate the short- and long-term results of 104 consecutive laparoscopic adrenalectomies performed during a period of 10 years in two specialist centers. One hundred four patients underwent laparoscopic adrenalectomy in two specialist centers in Italy between 1994 and 2003. Indications to laparoscopic adrenalectomy were aldosterone-secreting adenoma (20%), pheochromocytoma (24%), cortisol-secreting adenoma (11.5%), incidentaloma (26.9%), multiple endocrine neoplasia (MEN) type 2A (2.8%), adrenal metastases from lung cancer (3.8%), adrenal cyst (6.7%), and angiomyolipoma (3.8%). Transperitoneal anterior and lateral approaches were adopted in 17 and 84 patients, respectively. Retroperitoneal approach was adopted in three patients. Mean operative time was 108 +/- 39.1 minutes (range, 40-300 minutes). There was no correlation between adrenal tumor diameter and operative time. Mean intraoperative blood loss was 106 mL (range, 40-600 mL). Intraoperative complication rate and conversion rate were 4.8 per cent (5 cases). Laparoscopic adrenalectomy is a safe procedure. After a relatively short learning curve, it can be performed successfully by any surgeon with low operative morbidity and mortality. The size of the adrenal tumor should not be considered a contraindication to this procedure.

    Imhoof, M

    1985-01-01

    Interactive instructional radio programming is an innovative, inexpensive, and highly effective educational tool. In interactive radio programming, lessons are provided by a radio instructor, but unlike other radio education programs, the instructor prompts responses from the radio audience, provides pauses for audience responses, and then supplies the correct response to the prompt. The lessons are generally supervised by a classroom teacher, and the students respond to the radio prompts either orally or in writing. The lessons encourage student participation, and the programs frequently require more than 100 audience responses for each 1/2 hour of radio programing. The US Agency for International Development's Office of Education in the Bureau for Science and Technology researched and developed the tool during the last 10 years, and conducted highly successful experimental projects with it in Kenya, Nicaragua, and the Dominican Republic. In September 1984 a conference, jointly sponsored by the agency and Kenya's Ministry of Education, Science, and Technology, was held in Nairobi to demonstrate the new tool and to encourage other countries to utilize the approach. Participants visited rural classrooms in Kenya where they had an opportunity to observe how the technique was being successfully used in Kenya's Radio Language Arts Project. In view of the successful results attained in the experimental projects of the 3 countries noted above, the conference participants recommended that the technique should immediately be integrated into the national curricula of these countries, and that the approach should be more widely used in other countries. They noted that the technique is especially appropriate for use in primary schools and in nonformal adult education programs and that the tool is especially useful for teaching mathematics and second languages. They recommended that educators in developing countries develop interactive instructional radio programs, evaluate

    2011-03-01

    We study jamming of low aspect-ratio cylindrical Delrin grains in a vertical channel. Grain heights are less than their diameter so the grains resemble antacid tablets, coins, or poker chips. These grains are allowed to fall through a vertical channel with a square cross section where the channel width is greater than the diameter of a grain and constant throughout the length of the channel with no obstructions or constrictions. Grains are sometimes observed to form jams, stable structures supported by the channel walls with no support beneath them. The probability of jam occurrence and the strength or robustness of a jam is effected by grain and channel sizes. We will present experimental measurements of the jamming probability and jam strength in this system and discuss the relationship of these results to other experiments and theories.

    We experimentally study jamming of cylindrical grains in a vertical channel. The grains have a low aspect-ratio (height/diameter < 1) so their shape is like antacid tablets or poker chips. They are allowed to fall through a vertical channel with a square cross section. The channel width is greater than the diameter of a grain and constant throughout the length of the channel with no obstructions or constrictions. It is observed that grains sometimes jam in this apparatus. In a jam, grains form a stable structure from one side of the channel to the other with nothing beneath them. Jams may be strong enough to support additional grains above. The probability of a jam occurring is a function of the grain height and diameter. We will present experimental measurements of the jamming probability in this system and discuss the relationship of these results to other experiments and theories.

    Objectives: The aim of this clinical trial was to evaluate posterior indirect composite resin restoration ten years after placement luted with two different procedures. Study Design: In 23 patients 22 inlays/onlays (Group A) were luted using a dual-cured resin composite cement and 26 inlays/onlays (Group B) were luted using a light cured resin composite for a total of 48 Class I and Class II indirect composite resin inlays and onlays. The restorations were evaluated at 2 time points: 1) one week after placement (baseline evaluation) and 2) ten years after placement using the modified USPHS criteria. The Mann-Whitney and the Wilcoxon tests were used to examine the difference between the results of the baseline and 10 years evaluation for each criteria. Results: Numerical but not statistically significant differences were noted on any of the recorded clinical parameters (p>0.05) between the inlay/onlays of Group A and Group B. 91% and 94 % of Group A and B respectively were rated as clinically acceptable in all the evaluated criteria ten years after clinical function. Conclusions: Within the limits of the study the results showed after ten years of function a comparable clinical performance of indirect composite resin inlays/onlays placed with a light cure or dual cure luting procedures. Key words:Light curing composite, dual curing composite, indirect composite restoration, inlays/onlays, clinical trial. PMID:25810842

    2013-03-01

    Between 1999 and 2001, 90 patients underwent total hip replacement using the same uncemented acetabular and femoral components with a 28 mm metallic femoral head but with prospective randomisation of the acetabular liner to either Durasul highly cross-linked polyethylene or nitrogen-sterilised Sulene polyethylene. We assessed 83 patients at a minimum follow-up of ten years. Linear penetration of the femoral head was estimated at six weeks, six and 12 months and annually thereafter, using the Dorr method, given the non-spherical shape of the acetabular component. There was no loosening of any component; only one hip in the Sulene group showed proximal femoral osteolysis. The mean penetration of the femoral head at six weeks was 0.08 mm (0.02 to 0.15) for the Durasul group and 0.16 mm (0.05 to 0.28) for the Sulene group (p = 0.001). The mean yearly linear penetration was 64.8% lower for the Durasul group at 0.05 mm/year (sd 0.035) for the Sulene group and 0.02 mm/year (sd 0.016) for the Durasul (p < 0.001). Mean linear femoral head penetration at ten years was 61% less in the Durasul than Sulene group. Highly cross-linked polyethylene gives excellent results at ten years.

    2007-05-01

    The present study replicates our study of older adults' portrayal in Dutch television commercials conducted in 1993. The central question is whether older adults are being portrayed more visibly in Dutch television commercials and whether this portrayal has become more diverse compared to ten years ago. Based on a list of descriptions of all commercials broadcasted by public television channels in 2003 (N= 4767) 117 commercials featuring older adults were selected. By means of a quantitative content analysis it was examined whether and how older men and women are portrayed. It was concluded that although older adults are not more prevalent compared to ten years ago, their portrayal is more diverse with respect to their roles and the advertised products. Older adults were portrayed as more competent and less age-stereotypical in television commercials.

    1998-01-01

    During the post Challenger period, the National Aeronautics and Space Administration and Thiokol implemented changes to the Reusable Solid Rocket Motor (RSRM) contract to include provisions for contamination control to enhance the production environment. During the ten years since those agreements for contamination controls were made, many changes have taken place in the production facilities at Thiokol. These changes have led to the production of much higher quality shuttle solid rocket motors and improved cleanliness and safety of operations in the production facilities. The experience in contamination control over this past decade highlights the value these changes have brought to the RSRM program, and how the system can be improved to meet the challenges the program will face in the next ten years.

    Massachusetts's 2006 health reform legislation was intended to move the state to near-universal health insurance coverage and to improve access to affordable health care. Ten years on, a large body of research demonstrates sustained gains in coverage. But many vulnerable populations and communities in the state have high uninsurance rates, and among those with coverage, gaps in access and affordability persist. PMID:27605643

    1985-05-01

    Forty-seven patients with unilateral hip disease had a preoperative and postoperative gait analysis of total hip arthroplasty with a follow-up period of five to ten years. The object was to correlate the levels of function with mechanical loosening. Unilateral total hip arthroplasty in uncomplicated patients restored function to 80% of normal over a two- to four-year period. Patients followed longer than five years appeared to have an accelerated decline in function unassociated with pain. No Class C patient, regardless of age or gait velocity, developed loosening or required revision of the hip prosthesis. Survivorship studies revealed an 85%-90% incidence of loosening by the seventh postoperative year in Class A patients 55 years or younger and those walking preoperatively at more than 50% of normal gait velocity. In these same two groups of patients, the probability of revision for mechanical failure by ten years is 58% for age and 66% for fast walkers. The majority of patients in this study had a technical rating not acceptable by present standards so that these results represent most likely the worst prognosis for longevity of total hip arthroplasty. In high-risk patients, protected ambulation with crutches for six months postoperation may improve their prognosis.

    2009-01-01

    We demonstrate experimentally that the route to a jammed state for a set of bi-dispersed frictional disks, subjected to uni-axial compression from a random initial unjammed state, consists of a consolidation state, a fragile jammed state, and finally a rigid jammed state. In the consolidation regime, the pressure on the sides increases very slowly with the packing fraction {phi} and there are no detectable stress chains. In the fragile jammed state, stress chains are visible, the pressure increases exponentially with {phi}, and the fraction of moving disks drops exponentially. Eventually, a final regime where particle displacements are below our resolution and the pressure varies approximately linearly with {phi} is reached. We argue that this scenario is generic for ather mal frictional compressed particles.

    It is ten years since the Cartwright report was published, three years since the code of health and disability services consumers' rights was promulgated and two years since the code came into force which makes it due for review next year. This paper reviews the issues identified by Cartwright and the effect that her investigation into the "Unfortunate Experiment" has had on the provision of health services. Issues of clinical freedom, peer supervision and informed consent are discussed in relation to the Health and Disability Commissioner Act, the Privacy Act and concepts of partnership in health care. Some comments on the present state of the relationships between consumers and providers in the health system are included.

  11. Ten-year forecasts of water quality in Lake Michigan using a deterministic eutrophication model

    SciTech Connect

    Lesht, B.M.

    1984-03-01

    A dynamic, deterministic lake eutrophication model was used to forecast changes in Lake Michigan water quality over a ten-year simulation period. Emphasis was placed on changes in epiliminon phytoplankton biomass and in whole-lake total phosphorus concentration in response to changes in input phosphorus loads and to variations in winter conditions. Constant-condition simulations corresponding to current, increased, and reduced loads and to mild, average, and severe winters were used to establish bounds for the projected changes in water quality. Monte Carlo-type simulations were used to estimate the variance associated with the projections. Given the assumptions and limitations inherent in the modeling process, water quality in Lake Michigan is projected to improve slightly (reduced concentrations of phytoplankton and total phosphorus) over the next ten years. Year-to-year variations are significant, however, and will depend on loading and winter conditions. The variation in the projected values associated with the assumed fluctuations in loads and winter conditions is approximately 20 percent. 25 references, 20 figures, 4 tables.

    2005-03-01

    As reflected in the U.S. ''National Energy Policy'', nuclear energy has a strong role to play in satisfying our nation's future energy security and environmental quality needs. The desirable environmental, economic, and sustainability attributes of nuclear energy give it a cornerstone position, not only in the U.S. energy portfolio, but also in the world's future energy portfolio. Accordingly, on September 20, 2002, U.S. Energy Secretary Spencer Abraham announced that, ''The United States and nine other countries have agreed to develop six Generation IV nuclear energy concepts''. The Secretary also noted that the systems are expected to ''represent significant advances in economics, safety, reliability, proliferation resistance, and waste minimization''. The six systems and their broad, worldwide research and development (R&D) needs are described in ''A Technology Roadmap for Generation IV Nuclear Energy Systems'' (hereafter referred to as the Generation IV Roadmap). The first 10 years of required U.S. R&D contributions to achieve the goals described in the Generation IV Roadmap are outlined in this Program Plan.

    An NIH-appointed investigatory panel has found a pattern of data fabrication in John Darsee's biomedical research at Harvard Medical School's Cardiac Research Laboratory and has recommended that Darsee be denied federal research funds for the next ten years. Holding Harvard indirectly responsible for lax supervision, NIH is seeking repayment of federal funds used for Darsee's work and government inspection of the laboratory's new supervisory procedures. Recent evidence from Emory University, Darsee's previous employer, has cast suspicion on his work there, as well.

    There has been an increase in gun-related crime in Ireland over the last decade to gangland violence, especially in west Dublin. This places a burden on hospital services not previously encountered. The aim of this study was to examine the demographics of gunshot: injuries presenting to a Dublin teaching hospital, and the impact on radiology over a ten year period. A total of 65 gunshot injuries were seen. Mortality for high velocity wounds was much higher (10/23, 43%) than for low-velocity shotgun injuries (2/34, 6%).

    Meiosis is the crucial process by which sexually propagating eukaryotes give rise to haploid gametes from diploid cells. Several key processes, like homologous chromosomes pairing, synapsis, recombination, and segregation, sequentially take place in meiosis. Although these widely conserved events are under both genetic and epigenetic control, the accurate details of molecular mechanisms are continuing to investigate. Rice is a good model organism for exploring the molecular mechanisms of meiosis in higher plants. So far, 28 rice meiotic genes have been characterized. In this review, we give an overview of the discovery of rice meiotic genes in the last ten years, with a particular focus on their functions in meiosis. PMID:24656233

    2004-05-01

    The frequency of serial sexual murder has been widely discussed, and estimates of the number of victims in the United States range from 500 to 6000 per year. This study attempted to quantify the number of serial sexual murder victims in Virginia for a ten-year period. Multiple sources of data were utilized, including Federal Bureau of Investigation (FBI) case files, FBI's Violent Criminal Apprehension Program (ViCAP) reports, Virginia State Police ViCAP reports, Virginia Homicide Investigators Association, and the Virginia Division of Forensic Science DNA database, to effectively cull out all the known serial sexual murder victims for the given time period. Review of these records revealed a total of 28 victims of serial sexual murder, compared with a total of 5183 murder victims for the same ten-year period. The frequency of serial sexual victimization was 0.5% of all homicides for the given period. These results highlight the unusual frequency of serial sexual murder. PMID:15171171

    The development of cognitive functions and the sustainability of seizure control between two and ten years after epilepsy surgery were prospectively investigated in 17 children and adolescents. Intelligence quotient remained stable. Learning capacity improved. Verbal memory improved in half of the subjects and declined in half, whereas figurative memory declined in most patients. Working memory improved as did attention regarding sustained attention and impulse control. In contrast, reaction times were longer, and the auditory attention span was shorter. Executive functions were not affected. Six subjects (35%) were seizure free at the 10-year follow-up, and a seizure reduction of more than 75% had been achieved in 13 (76%). Seizure control improved in five and seizures recurred in two subjects between the two- and the 10-year follow-up.

    Elevated atmospheric CO2 ([CO2]) is assumed to increase primary production, particularly in desert systems through stimulatory effects on plant water-use efficiency. We examined the effects of elevated [CO2] at the Nevada Desert FACE (Free-air CO2 Enrichment) Facility (NDFF) in an intact Mojave Desert ecosystem. At the NDFF, ambient and elevated [CO2] levels were 360 and 550 μmol mol-1 [CO2], respectively. CO2 treatments were applied continuously from 1997-2007 in intact plots 25 m in diameter. While other studies focused on soil and root responses to elevated [CO2], our study focused on aboveground production of annuals and perennial plants. In 1997, diameters and heights of all perennial individuals were recorded and mapped. In 2007, diameters and heights were re-measured and aboveground biomass was harvested for every mapped perennial individual. Harvest data were used to construct regressions for twenty perennial species to predict starting biomass based on diameters and heights. Annual plants were harvested yearly at peak biomass from permanent transects. We found no significant effect of elevated [CO2] on total perennial plant biomass or cover at the end of the experiment. Regardless of [CO2] treatment, perennial cover increased while total biomass did not change over the ten years of the experiment. Perennial biomass allocation to vegetative, twig and woody biomass was not differentially affected by elevated [CO2], although leaf area index increased under elevated [CO2]. Similarly, there was no consistent elevated [CO2] effect on yearly production of annual (ephemeral) plants, although an exotic grass (Bromus madritensis subsp. rubens) exhibited a higher relative stimulation in production at elevated [CO2] than did native dicot and grass species. Other studies in our research group have shown that increases in production are only seen in wet years during the ten-year period of CO2 treatments at the NDFF, and so future effects of rising [CO2] may primarily

    This Idaho National Laboratory (INL) Ten-Year Site Plan (TYSP) describes the strategy for accomplishing the long-term objective of sustaining the INL infrastructure to meet the Department of Energy Office of Nuclear Energy (DOE-NE) mission: to promote nuclear power as a resource capable of making major contributions in meeting the nation’s energy supply, environmental and energy security needs. This TYSP provides the strategy for INL to accomplish its mission by: (1) linking R&D mission goals to core capabilities and infrastructure requirements; (2) establishing a ten-year end-state vision for INL facility complexes; (3) identifying and prioritizing infrastructure needs and capability gaps; (4) establishing maintenance and repair strategies that allow for sustainment of mission-critical (MC) facilities; and (5) applying sustainability principles to each decision and action. The TYSP serves as the infrastructure-planning baseline for INL; and, though budget formulation documents are informed by the TYSP, it is not itself a budget document.

  20. A Ten Year Retrospective on Environmental Justice: What Have We Learned?

    Scott, Michael J.; Jaksch, John A.; Cort, Katherine A.

    2005-03-01

    Beginning in 1994, Executive Order 12898 has directed federal executive agencies to identify and address, as appropriate, disproportionately high and adverse health or environmental effects of their programs, policies, and activities on minority and low income populations. The policy behind the Executive Order was to prevent minority and low income groups from bearing disproportionate adverse environmental consequences of federal actions. During the last ten years, federal agencies have implemented Executive Order 12898, and some also have developed explicit procedures or guidance for the steps that need to be taken during the preparation of environmental impact statements. Based on the authors’ experience, the paper examines how environmental justice practice has evolved in the ten years since the original Executive Order was issued. This evolution has been both procedural and substantive. The paper examines how the actual practice of environmental justice analysis has progressed in federal agencies that deal with waste management issues. Reference is made to changes in case law and agency practice. The 2000 Census of Population and the ongoing development of geographic information systems in particular have made it easier to identify minority and low-income populations at risk. At the same time, a number of stakeholder groups have taken positions over specific federal actions that have given rise to novel issues and challenges for analysts. The paper discusses how NEPA practice is evolving to deal with these issues and challenges.

    Aims The interest in unicompartmental knee arthroplasty (UKA) for medial osteoarthritis has increased rapidly but the long-term follow-up of the Oxford UKAs has yet to be analysed in non-designer centres. We have examined our ten- to 15-year clinical and radiological follow-up data for the Oxford Phase III UKAs. Patients and Methods Between January 1999 and January 2005 a total of 138 consecutive Oxford Phase III arthroplasties were performed by a single surgeon in 129 patients for medial compartment osteoarthritis (71 right and 67 left knees, mean age 72.0 years (47 to 91), mean body mass index 28.2 (20.7 to 52.2)). Both clinical data and radiographs were prospectively recorded and obtained at intervals. Of the 129 patients, 32 patients (32 knees) died, ten patients (12 knees) were not able to take part in the final clinical and radiological assessment due to physical and mental conditions, but via telephone interview it was confirmed that none of these ten patients (12 knees) had a revision of the knee arthroplasty. One patient (two knees) was lost to follow-up. Results The mean follow-up was 11.7 years (10 to 15). A total of 11 knees (8%) were revised. The survival at 15 years with revision for any reason as the endpoint was 90.6% (95% confidence interval (CI) 85.2 to 96.0) and revision related to the prosthesis was 99.3% (95% CI 97.9 to 100). The mean total Knee Society Score was 47 (0 to 80) pre-operatively and 81 (30 to 100) at latest follow-up. The mean Oxford Knee Score was 19 (12 to 40) pre-operatively and 42 (28 to 55) at final follow-up. Radiolucency beneath the tibial component occurred in 22 of 81 prostheses (27.2%) without evidence of loosening. Conclusion This study supports the use of UKA in medial compartment osteoarthritis with excellent long-term functional and radiological outcomes with an excellent 15-year survival rate.

    In 2000, there was no way for an Ontario student to obtain a credential in optics, laser or photonics without going through graduate school. This was in, arguably, the world-leading jurisdiction in photonics-enabled telecommunications industry. To alleviate this problem and supply the job market with highly-qualified people in the field of optics and photonics, the Ontario Centres of Excellence - then as Photonics Research Ontario - partnered with Algonquin College (Ottawa) and Niagara College (Welland) to establish over the past decade a suite of programs: a 1-year Certificate in Advanced Lasers, a 2-year Diploma for Photonics Engineering Technician, a 3-year Diploma for Photonics Engineering Technologists and a 4-year Bachelor of Applied Technology - Photonics. Much has been learnt along the way - the crucial need for industrial partner and government support, for example - and many course corrections had to be made (telecom bust, anyone?). The author will share the results of this 10-year journey so far, the lessons learnt, and a view to the next ten years for these programs and photonics education in Ontario in general.

    This paper reports the results of a 10-year follow-up of two variations of a couples group preventive intervention offered to couples in the year before their oldest child made the transition to kindergarten. 100 couples were randomly assigned to (1) a low-dose control condition, (2) a couples group meeting for 16 weeks that focused more on couple relationship issues among other family topics, or (3) a couples group meeting for 16 weeks that focused more on parenting issues among other family issues, with an identical curriculum to condition (2). Earlier papers reported that both variations of the intervention produced positive results on parent-child relationships and on the children’s adaptation to kindergarten and 1st grade, and that the groups emphasizing couple relationships also had additional positive effects on couple interaction quality. The present paper uses growth curve analyses to examine intervention effects extending from the children’s transition to kindergarten to the transition to high school – ten years after the couples groups ended. There were 6-year positive effects of the pre-kindergarten interventions on observed couple interaction and 10-year positive effects on both parents’ marital satisfaction and the children’s adaptation (hyperactivity and aggression). Discussion includes a focus on the implications of these results for family policy, clinical practice, and the need to include a couples focus in preventive interventions to strengthen family relationships and enhance children’s adaptation to school.

    A pack of two to eight adult wolves (Canis lupus arctos) and their pups was observed during ten summers (1986-95) on Ellesmere Island, Northwest Territories, Canada. The author habituated the wolf pack to his presence in the first summer and reinforced the habituation each summer thereafter. The first alpha female produced four to six pups each year between 1986 and 1989. However, her daughter, who succeeded her as the alpha female, produced only one to three pups each year between 1990 and 1992 and in 1994, and apparently did not whelp in 1993 or in 1995. The tenure of the first alpha male was at least two years, and his successor was alpha male for the remaining eight years of the study. The wolf pack was characterized by highly variable annual productivity. The second alpha male-and-female breeding pair likely was an older brother and a younger sister. Early survival of wolf pups was high and constant, with all pups surviving through August of their first year. The pack's demography was consistent with what is known for wolf packs in other regions of North America, but its productivity was more typical of arctic packs.

    The use of acupuncture in inducing delivery has a long history in China. With progress over time, it has been applied in many aspects. For further study of acupuncture in delivery, this paper analyzed the papers using acupuncture in delivery in the past ten years in mainland China. 87 literatures were picked out by searching relevant electronic databases and bibliographies of relevant journals. The analysis showed randomized controlled trials that were the major type of research, while preclinical researches and literature reviews only account for around ten percent, respectively. Clinical researches indicated that acupuncture can relieve labor pain, promote maternal uterine contraction, shorten birth process, and treat postpartum disorders. Preclinical researches found that acupuncture can adjust certain hormones and improve uterus contraction of late-stage pregnant rats. However, due to lack of large multicenter randomized controlled clinical trials, standardized evaluations of clinical effects in clinical researches and detailed mechanism study in preclinical researches and unequivocal conclusions about the effectiveness, efficacy, and mechanisms of acupuncture in this field cannot be obtained from those researches yet. Further clinical and preclinical studies about the use of acupuncture in delivery with improved methodology is still needed. PMID:24688593

    Nonlinear sound is an extreme phenomenon typically observed in solids after violent explosions. But granular media are different. Right when they jam, these fragile and disordered solids exhibit a vanishing rigidity and sound speed, so that even tiny mechanical perturbations form supersonic shocks. Here, we perform simulations in which two-dimensional jammed granular packings are dynamically compressed and demonstrate that the elementary excitations are strongly nonlinear shocks, rather than ordinary phonons. We capture the full dependence of the shock speed on pressure and impact intensity by a surprisingly simple analytical model.

    Over a period of ten years (1983-1992), 134 malaria cases admitted to University Hospital, Kuala Lumpur (UHKL) were analysed. Malays constituted 27.6%, Chinese 29.8%, Indians 9.7%, Indonesians 16.4% and other foreigners 16.4%. Therefore, of the total number of cases, foreigners constituted 32.8% (44) of all the malaria cases admitted to UHKL. Fifteen of these foreigners had chloroquine-resistant strains of malarial parasites. Three species of malaria were reported of which Plasmodium falciparum constituted the most (46.3%) (80% of these developed resistance to chloroquine). Plasmodium vivax was confirmed in 44.8% (10% of these developed resistance to chloroquine) and there was only one case of Plasmodium malarie infection.

    FCC reactor closed cyclones were first commercialized ten years ago and have now been installed in over 22 FCC units worldwide. Cumulative commercial experience has shown significant yield benefits, in some cases higher than first estimated, and excellent reliability. By nearly eliminating post-riser cracking, they reduce dry gas make and produce higher yields of desirable liquid products. Trouble-free operation with closed cyclones is attributed to proper design, instrumentation, and operating procedures. The Mobil-Kellogg Closed Cyclone technology is the only design offered for license which uses the positive-pressure riser cyclone system which has proven to be least sensitive to upsets. This paper traces the development and commercialization of closed cyclones, discusses differences between competing closed cyclone designs, and documents the benefits which have been observed for Mobil-Kellogg Closed Cyclones.

    Since its invention in 2006, the broadband chirped pulse Fourier transform spectrometer has transformed the field of microwave spectroscopy. The technique enables the collection of a ≥10 GHz bandwidth spectrum in a single shot of the spectrometer, which allows broadband, high-resolution microwave spectra to be acquired several orders of magnitude faster than what was previously possible. We discuss the advantages and challenges associated with the technique and look back on the first ten years of chirped pulse Fourier transform spectroscopy. In addition to enabling faster-than-ever structure determination of increasingly complex species, the technique has given rise to an assortment of entirely new classes of experiments, ranging from chiral sensing by three-wave mixing to microwave detection of multichannel reaction kinetics. However, this is only the beginning. Future generations of microwave experiments will make increasingly creative use of frequency-agile pulse sequences for the coherent manipulation and interrogation of molecular dynamics.

    This study aimed to analyze fluoride concentration in the public water supply in Chapecó, Santa Catarina State, Brazil, from 1995 to 2005 and to assess the effectiveness of a fluoridation quality intervention in 2003. A total of 989 water samples were analyzed. Fluoride concentrations were classified according to three different criteria used in Brazil. The city conducted a political and legal intervention in 2003. The Prais-Winsten procedure was used to evaluate the fluoride concentrations over time. In the ten years, the water fluoridation system showed 46%, 32%, and 43% of adequate samples, depending on the criterion. Prior to the municipal intervention, the proportion of adequate samples was 40%, 26%, and 36%, increasing to 63%, 49%, and 61% after the intervention, according to the three criteria. Fluoride concentration improved after the municipal intervention. On-going surveillance is recommended, including water fluoridation, dental caries, and dental fluorosis.

    Ten-year protocol biopsies were performed in 16 patients treated with calcineurin inhibitor (CNI) continuously. All kidney grafts were functioning well at the time of biopsy with the mean serum creatinine level of 1.6 +/- 0.8 mg/dL. The specimen of biopsy showed various degrees of tissue injury. According to the Banff grading, allograft glomerulopathy (cg) was observed in one case. Interstitial fibrosis (ci) and tubular atrophy (ct) were observed more frequently in 13 (81%) and 15 (93%) cases, respectively. Fibrous intimal thickening (cv) was seen in one (7%) case. Arteriolar hyaline thickening (ah) was seen in 14 (87%) cases. These findings were associated with chronic rejection in one case, recurrence of original disease in four (25%) cases, toxicity of CNI in 14 (87%) cases. Longer follow-up studies are needed to confirm whether CNI should be continued or not in the long-term period following kidney transplantation for better graft survival.

    Over a ten year period of running a joint ophthalmological/genetic clinic, 387 index patients were advised, and a further 260 individuals (relatives of the above) were examined and counselled. Determination of the precise diagnoses and modes of inheritance in the index patients necessitated retinal function tests in 267 (69%) and examination of 84 of their parents and 23 sisters and daughters. Finally, 41% of index patients and 39% of their relatives were given high risks for transmitting an autosomal dominant or X-linked disorder to their children. It is noteworthy that 16% of these high-risk index patients and 66% of these high-risk relatives had no visual symptoms; ophthalmological expertise was required to assess the significance of their minor signs. It was concluded that an active Register is required for contacting relatives outside the nuclear family, and for future recall of children currently too young for carrier tests or genetic counselling.

  18. Sediment Movement Near a Tropical Wood Jam

    Cadol, D.; Wohl, E.

    2008-12-01

    One mechanism by which wood interacts with sediment transport is the trapping of sediment behind jams. In tropical streams, higher discharge per unit of contributing area and higher microbial diversity relative to temperate zones are likely to cause in-stream wood to be more transient. This may reduce the residence time of jams, also reducing wood-induced sediment storage. To begin to evaluate this possibility, tracer clasts, scour chains, and wood pieces were surveyed four times from June 2007 to June 2008 at a wood jam in a stream in Costa Rica. At the study site the moderate gradient (3.2%) stream drains 1.6 km2 of preserved old-growth tropical wet forest of La Selva Biological Station. The mean grain size of the bed material is 205 mm, ranging from coarse sand to boulders, with discontinuous bedrock outcrops on both banks. Distance traveled by the tracer clasts was positively correlated with both maximum and average daily rainfall during the time between surveys. Between the first two surveys, a new accumulation of wood in the jam blocked the thalweg and redirected the majority of flow around the side of the jam. A 15-cm-thick wedge of sediment was deposited behind the blockage, and gravel bars adjacent to and immediately downstream of the jam were scoured by as much as 30 cm. The majority of the gravel sized tracer clasts placed upstream of the jam were not recovered and were presumably incorporated into the sediment wedge. Tracer clasts placed in the portion of the channel affected by the redirected flow were transported downstream as much as 47 m. Clasts larger than D55 (220 mm) were not transported in the course of the study. The jam and key pieces persisted for the entire study period, and the number of pieces in the jam stayed nearly constant. However, the structure was modified and only 46% of the original pieces were retained for the full year. The clast transport distance was positively correlated with wood turnover rate for the three inter

    Bilateral vocal fold immobility (BVFI) is commonly caused by injury to the recurrent laryngeal nerve (RLN) and leads to stridor and dyspnea of varying onsets. A retrospective study was done at the Department of Otorhinolaryngology of Universiti Kebangsaan Malaysia Medical Centre on laser microsurgical posterior cordectomy for BVFI. The objectives were to identify the average duration of onset of stridor from the time of insult and to evaluate the outcome of laser posterior cordectomy as a surgical option. From 1997 to 2007, a total of 31 patients with BVFI were referred for surgery. Twelve patients had tracheostomy done prior to the procedure, whereas 19 patients were without tracheostomy. Ten patients were successfully decannulated, and only 4 patients had complications related to the procedure. The minimum onset of stridor was 7 months, maximum onset of stridor was 28 years, and the mean onset of stridor was 8.7 years. The commonest complication observed was posterior glottic adhesion following bilateral posterior cordectomy. Laser endolaryngeal posterior cordectomy is an excellent surgical option as it enables successful decannulation or avoidance of tracheostomy in patients with BVFI. The onset of stridor took years after the insult to the recurrent laryngeal nerves. PMID:27660547

    During the past ten years of the Association of American State Geologists-Mineral Management Service Continental Margins Program, the Maryland Geological Survey investigated the sedimentological, paleontological, stratigraphical and geophysical character of Maryland's inner continental shelf. Based on seismic records and sedimentological analyses completed during the first four years, a late Quaternary stratigraphic model was developed. Five distinct stratigraphic units were identified and described on the Maryland inner shelf. These units represent late Pleistocene interglacial deposits, the oldest of which corresponds to pre-Illinoian (oxygen-isotope stages 7 and/or 9) transgressive shelf sands. Overlying the Q1 unit, the Q2 unit is a 6-meter thick mud sequence of oxygen-isotope stage 5 (128-75 ka) age. Units Q3 and Q4 representing fluvial and leading edge estuarine deposits (oxygen-isotope stages 4, 3 and 2) filled numerous paleochannels that were incised into units Q2 and Q1. Modern trailing-edge transgressive shelf shoals (Unit Q5) discontinuously cap the sequence. The 5th and 6th years studies reported on the economic minerals of surficial and cored sediments. Vibracores collected off the Maryland's shelf during previous studies were analyzed for mineral types and abundances, weight percent of general size fractions, and heavy mineral (HM) content. Mineralogic maturity indices were compiled to correlate the THM and economic heavy minerals (EHM) abundances with position offshore, sediment type, and the indices themselves. For the 7th year, the Maryland Geological Survey re-examined geophysical records and lithological data originally collected by the Army Corps of Engineers to locate and assess beach fill borrow areas for the Ocean City Beach Replenishment Project. Data from 163 vibracores and over 300 kilometers of high-resolution seismic profile records collected off Ocean City, Maryland, supported the stratigraphic model developed by MGS during the first

  6. Naive (commonsense) geography and geobrowser usability after ten years of Google Earth

    Hamerlinck, J. D.

    2016-04-01

    In 1995, the concept of ‘naive geography’ was formally introduced as an area of cognitive geographic information science representing ‘the body of knowledge that people have about the surrounding geographic world’ and reflecting ‘the way people think and reason about geographic space and time, both consciously and subconsciously’. The need to incorporate such commonsense knowledge and reasoning into design of geospatial technologies was identified but faced challenges in formalizing these relationships and processes in software implementation. Ten years later, the Google Earth geobrowser was released, marking the beginning of a new era of open access to, and application of, geographic data and information in society. Fast-forward to today, and the opportunity presents itself to take stock of twenty years of naive geography and a decade of the ubiquitous virtual globe. This paper introduces an ongoing research effort to explore the integration of naive (or commonsense) geography concepts in the Google Earth geobrowser virtual globe and their possible impact on Google Earth's usability, utility, and usefulness. A multi-phase methodology is described, combining usability reviews and usability testing with use-case scenarios involving the U.S.-Canadian Yellowstone to Yukon Initiative. Initial progress on a usability review combining cognitive walkthroughs and heuristics evaluation is presented.

    Mt Ontake in central Japan suddenly erupted on 27(th) September 2014, killing 57 people with 6 still missing. It was a hydro-volcanic eruption and new magmatic material was not detected. There were no precursor signals such as seismicity and edifice inflation. It is difficult to predict hydro-volcanic eruptions because they are local phenomena that only affect a limited area surrounding the explosive vent. Here we report a long-term helium anomaly measured in hot springs close to the central cone. Helium-3 is the most sensitive tracer of magmatic volatiles. We have conducted spatial surveys around the volcano at once per few years since November 1981. The (3)He/(4)He ratios of the closest site to the cone stayed constant until June 2000 and increased significantly from June 2003 to November 2014, while those of distant sites showed no valuable change. These observations suggest a recent re-activation of Mt Ontake and that helium-3 enhancement may have been a precursor of the 2014 eruption. We show that the eruption was ultimately caused by the increased input of magmatic volatiles over a ten-year period which resulted in the slow pressurization of the volcanic conduit leading to the hydro-volcanic event in September 2014.

    2015-04-01

    The field of Physics Education Research (PER) has for over thirty years provided insights into student thinking and guided the development and assessment of reformed teaching strategies and practices in introductory physics courses. In the last decade or so, researchers have expanded the domain of such investigations to upper-division courses where undergraduate majors study more advanced content and begin to see themselves as future physicists. The upcoming Focused Collection on Upper Division PER brings together work from researchers active in these new frontiers of PER. In this presentation we provide an overview of the studies in this collection, which offer to the PER and greater physics education communities: new insights about the thinking, behavior, and beliefs of students in the upper division; new tools to innovate instruction, assess student learning, and evaluate teaching effectiveness; and groundbreaking studies of identity development and ``thinking like a physicist'' among physics majors. In this session we also recognize the ten-year anniversary of Physical Review Special Topics: Physics Education Research, an occasion that we will celebrate with an informal reception immediately following the conclusion of this invited session.

    Mt Ontake in central Japan suddenly erupted on 27th September 2014, killing 57 people with 6 still missing. It was a hydro-volcanic eruption and new magmatic material was not detected. There were no precursor signals such as seismicity and edifice inflation. It is difficult to predict hydro-volcanic eruptions because they are local phenomena that only affect a limited area surrounding the explosive vent. Here we report a long-term helium anomaly measured in hot springs close to the central cone. Helium-3 is the most sensitive tracer of magmatic volatiles. We have conducted spatial surveys around the volcano at once per few years since November 1981. The 3He/4He ratios of the closest site to the cone stayed constant until June 2000 and increased significantly from June 2003 to November 2014, while those of distant sites showed no valuable change. These observations suggest a recent re-activation of Mt Ontake and that helium-3 enhancement may have been a precursor of the 2014 eruption. We show that the eruption was ultimately caused by the increased input of magmatic volatiles over a ten-year period which resulted in the slow pressurization of the volcanic conduit leading to the hydro-volcanic event in September 2014.

    Objective To compare the 10-year retest stability of normal traits, pathological traits, and personality disorder dimensions in a clinical sample. Method Ten-year rank order stability estimates for the Revised NEO Personality Inventory, Schedule for Nonadaptive and Adaptive Personality, and Diagnostic Interview for DSM-IV Personality Disorders were evaluated before and after correcting for test-retest dependability and internal consistency in a clinical sample (N = 266). Results Dependability corrected stability estimates were generally in the range of .60–.90 for traits and .25–.65 for personality disorders. Conclusions The relatively lower stability of personality disorder symptoms may indicate important differences between pathological behaviors and relatively more stable self-attributed traits and imply that a full understanding of personality and personality pathology needs to take both traits and symptoms into account. The Five-Factor Theory distinction between basic tendencies and characteristic adaptations provides a theoretical framework for the separation of traits and disorders in terms of stability in which traits reflect basic tendencies that are stable and pervasive across situations, whereas personality disorder symptoms reflect characteristic maladaptations that are a function of both basic tendencies and environmental dynamics.

    Global Health Partnerships (GHPs) have contributed significantly to improved global health outcomes as well as the manner in which global health is governed. Yet in a context of an increasingly complex global health landscape, resource scarcity and a shift from disease-specific to systems strengthening approaches, it is important to continually enhance and apply our understanding of how to improve GHP performance. The authors reviewed and synthesised findings from eight independent evaluations of GHPs as well as research projects conducted by the authors over the past several years, the most recent of which involved semi-structured discussions with 20 'partnership pioneers'. This paper presents the major drivers of the GHP trend, briefly reviews the significant contributions of GHPs to global health and sets out common findings from evaluations of these global health governance instruments. The paper answers the question of how to improve GHP performance with reference to a series of lessons emerging from the past ten years of experience. These lessons cover the following areas: • Value-added and niche orientation • Adequate resourcing of secretariats • Management practices • Governance practices • Ensuring divergent interests are met • Systems strengthening • Continuous self-improvement. These and other critical reflections inform the 'what's next' agenda for GHP development.

    This cross sectional record based institutional study was conducted in the Department of Obstetrics & Gynaecology, Burdwan Medical College, Burdwan over ten years (1999-2008) aiming analysis of eclamptic mothers for evaluation of maternal and perinatal outcome with different anticonvulsant medications. Total 5991 pregnant mothers with eclampsia admitted in the inpatient department of the tertiary care teaching hospital were recruited for the study, irrespective of their previous antenatal check up history. Subjects with known seizure disorders were excluded from the study. The subjects were managed according to standard regimens (Menon, Ph-sodium, diazepam & magnesium sulphate) and results were documented in standardised format. Case fatality rate, mean induction delivery time & birth-weight, perinatal mortality rates were recorded. Study reveals that the incidence of eclampsia <20 years was 6.97% and majority (5.41%) came from rural areas. Eclampsia was noted primarily in primigravida (7.43%) and unbooked (6.41%) mothers. Ante partum eclampsia predominated (64%) and incidence of caesarean section was 22.25%.The overall case fatality rate was 6.05% and eclampsia contributed 27.85% of all maternal deaths during the last two years of the study period. The overall incidence of low birth weight baby was 26.96% and perinatal mortality was 30.33% (1411/4651).The incidence of perinatal mortality and low birth weight babies are lower in the last 4 years when compared to earlier studies. Proper socio-demographic assessment of pregnancy with eclampsia, planned delivery, shorter induction delivery interval, good control of convulsion by magnesium sulphate, intensive intranatal monitoring causes less maternal and perinatal morbidity and mortality.

    2013-01-01

    Background Medical school attrition is important - securing a place in medical school is difficult and a high attrition rate can affect the academic reputation of a medical school and staff morale. More important, however, are the personal consequences of dropout for the student. The aims of our study were to examine factors associated with attrition over a ten-year period (2001–2011) and to study the personal effects of dropout on individual students. Methods The study included quantitative analysis of completed cohorts and qualitative analysis of ten-year data. Data were collected from individual student files, examination and admission records, exit interviews and staff interviews. Statistical analysis was carried out on five successive completed cohorts. Qualitative data from student files was transcribed and independently analysed by three authors. Data was coded and categorized and key themes were identified. Results Overall attrition rate was 5.7% (45/779) in 6 completed cohorts when students who transferred to other medical courses were excluded. Students from Kuwait and United Arab Emirates had the highest dropout rate (RR = 5.70, 95% Confidence Intervals 2.65 to 12.27;p < 0.0001) compared to Irish and EU students combined. North American students had a higher dropout rate than Irish and EU students; RR = 2.68 (1.09 to 6.58;p = 0.027) but this was not significant when transfers were excluded (RR = 1.32(0.38, 4.62);p = 0.75). Male students were more likely to dropout than females (RR 1.70, .93 to 3.11) but this was not significant (p = 0.079). Absenteeism was documented in 30% of students, academic difficulty in 55.7%, social isolation in 20%, and psychological morbidity in 40% (higher than other studies). Qualitative analysis revealed recurrent themes of isolation, failure, and despair. Student Welfare services were only accessed by one-third of dropout students. Conclusions While dropout is often multifactorial, certain red

  16. Ten years of negotiating rights around maternal health in Uttar Pradesh, India

    2011-01-01

    Background Preventable maternal mortality and morbidity have been globally recognized as human rights issues. Maternal mortality in India is among the highest in the world, and reflects inequity in access to healthcare: women from certain states as well as poorer women and less literate women appear to be significantly disadvantaged. The government of India has been attempting to improve maternal outcomes through a cash transfer within the National Rural Health Mission to encourage women to come to hospitals for childbirth. Methods This paper reviews documents of the last ten years describing the experiences of a Non-Governmental Organisation, SAHAYOG, in working with a civil society platform, the Healthwatch Forum, to develop ‘rights based’ strategies around maternal health. The paper builds an analysis using recent frameworks on accountability and gendered rights claiming to examine these experiences and draw out lessons regarding rights claiming strategies for poor women. Results The examination of documents over the last ten years indicates defined phases of development in the evolution of SAHAYOG’s understanding and of the shifts in strategy among SAHAYOG and its close allies, and responses by the state. The first three stages depict the deepening of SAHAYOG’s understanding of the manner in which poor and marginalized women negotiate their access to health care; the fourth stage explores a health system intervention and the challenges of working from within civil society in alliance with poor and marginalized women. Conclusion The findings from SAHAYOG’s experiences with poor Dalit women in Uttar Pradesh reveal the elements of social exclusion within the health system that prevent poor and marginalized women from accessing effective lifesaving care. Creating a voice for the most marginalised and carving space for its articulation impacts upon the institutions and actors that have a duty to meet the claims being made. However, given the accountability

    Plant phenology is the best indicator of terrestrial ecosystem response to climate change and it becomes a hot issue in the study of global change. The forest in northeast of China plays an important part in global forest ecosystem. In this paper, yearly integrated Normalized Difference Vegetation Index (NDVI) of forest vegetation in northeast China was calculated based on Spot Vegetation datasets from 2001-2010, which has been filtered using Savtiky-Galoy method. And then, the yearly integrated NDVI profile was fitted using a logistic model. Two key parameters of forest phenology (start of season, SOS; end of season, EOS) were extracted according to the greatest rate of curvature of fitted cumulative NDVI and the length of forest phenology (length of season, LOS) was also analyzed. The main conclusions of this paper are (1) SOS mainly occurs in the 110th-140th day and EOS in 260th and 290th day. SOS displays a marked delayed from south to north while EOS gradually advances. However, the changes of SOS and EOS in ten years are not obvious. (2) Corresponding to the SOS and EOS, LOS of forest in study area mainly occurs in the 120th-160th day; however, it is spatially heterogeneous. LOS of forest in Greater Khingan Mountains is shorter (about 120-140 day) than forests in Xiao Hinggan Ling and Changbai Mountains (about 160 day). The results in this paper are concordant with records of phenology in situ measurements and previous researches in the same area. It indicates that forest phenophases using method in this paper from Spot Vegetation dataset is feasible.

    When an area of education, and more particularly the research within this area, is aimed to development, a basic requirement is the existence of a regular publication that accounts for the scientific production in that area. This study aims to analyze 10 years of Latin-American Journal of Astronomy Education (RELEA). Publishing policies of the RELEA and their context are discussed in relation to submission, refereeing and publication. The 75 articles published in 18 editions are analyzed and classified by: year of publication, edition, the authors' institutions, school level, study focus and content. The results present trends and shortcomings of the production. A comparison with the number of articles published in other Brazilian journals of education and an analysis of the international scene in relation to other type publications along these ten years is made. Given that this journal is now consolidated, its future prospects in the international landscape are further considered. The challenges related to article submission are discussed: how to increase their number, the submission of Latin American countries, and how to bring in the issues and subjects not addressed until now. It is also considered the possibility of encouraging graduate studies, new lines of research in astronomy education, and dissemination of material in schools and universities for teachers and students. Finally, future possibilities are discussed given the IAU development programs. For example, more article submission from Portuguese-speaking countries with the support of Regional Nodes and Language Expertise Centers, and opportunities for volunteer IAU members and global projects for the development of astronomy education.

    Abstract The Register of Antarctic Marine Species (RAMS) is a marine species database that manages an authoritative taxonomic list of species occurring in the Southern Ocean. RAMS links with several other initiatives managing biogeographic or genomics information. The current paper aims to briefly present RAMS and provides an updated snapshot of its contents, in the form of a DarwinCore checklist (available through http://ipt.biodiversity.aq/resource.do?r=rams) and illustrative barplots. Moreover, this article presents a ten year appraisal (since the creation of RAMS). This appraisal first focuses on RAMS bibliometrics. We observed that RAMS was cited (Google Scholar) in 50 distinct publications among which 32 were peer-reviewed in 18 different journals. Three journals (Antarctic Science, Polar Biology, ZooKeys) represent almost 40% of these peer-review publications. The second appraisal focuses on the evolution of new RAMS records. We observed an important decrease in data additions since 2011. As a case study, we focused on an original dataset for a specific group (Asteroidea, Echinodermata). It appears that around one hundred species of asteroids are lacking in RAMS despite the relatively high availability of these data. This suggests that the users’ community (or collaborative projects such as AquaRES) could be helpful in order to maintain the RAMS database over the long term. PMID:26478709

    The Performance Engineering Institute (PERI) originally proposed a tiger team activity as a mechanism to target significant effort optimizing key Office of Science applications, a model that was successfully realized with the assistance of two JOULE metric teams. However, the Office of Science requested a new focus beginning in 2008: assistance in forming its ten year facilities plan. To meet this request, PERI formed the Architecture Tiger Team, which is modeling the performance of key science applications on future architectures, with S3D, FLASH and GTC chosen as the first application targets. In this activity, we have measured the performance of these applications on current systems in order to understand their baseline performance and to ensure that our modeling activity focuses on the right versions and inputs of the applications. We have applied a variety of modeling techniques to anticipate the performance of these applications on a range of anticipated systems. While our initial findings predict that Office of Science applications will continue to perform well on future machines from major hardware vendors, we have also encountered several areas in which we must extend our modeling techniques in order to fulfill our mission accurately and completely. In addition, we anticipate that models of a wider range of applications will reveal critical differences between expected future systems, thus providing guidance for future Office of Science procurement decisions, and will enable DOE applications to exploit machines in future facilities fully.

    Biological disease-modifying antirheumatic drugs (bDMARDs) for rheumatoid arthritis (RA) treatment were among the first high-cost medicines to be subsidised in Australia. High-cost medicines pose several challenges to the Australian National Medicines Policy, which aims to provide timely access to effective medicines at a cost individuals and the community can afford. Thus, novel restriction criteria were developed to encourage cost-effective use of bDMARDs. Government expenditure on bDMARD subsidies for RA treatment grew to about $383 million in 2014. Evidence that initiation and continuation criteria for bDMARDs meet usually applied cost-benefit criteria is lacking. The combined expenditure on tocilizumab, certolizumab pegol and golimumab (added to the Australian Government's Pharmaceutical Benefits Scheme in 2010) was $93 million in 2014, which is 210% over the initial estimate. Present and future challenges with regard to bDMARDs for RA and other high-cost drugs include improved expenditure predictions, monitoring of cost-effectiveness in relation to actual use and strategic development, regulation and use of biosimilars. Ten years of documentation on clinical and laboratory findings indicating eligibility to initiate and continue on bDMARDs remains un-used. These data represent an untapped opportunity to promote quality of use of bDMARDs and biosimilars and to improve cost predictions for high-cost drugs.

    Whether dinosaurs were in a long-term decline or whether they were reigning strong right up to their final disappearance at the Cretaceous-Paleogene (K-Pg) mass extinction event 66 Mya has been debated for decades with no clear resolution. The dispute has continued unresolved because of a lack of statistical rigor and appropriate evolutionary framework. Here, for the first time to our knowledge, we apply a Bayesian phylogenetic approach to model the evolutionary dynamics of speciation and extinction through time in Mesozoic dinosaurs, properly taking account of previously ignored statistical violations. We find overwhelming support for a long-term decline across all dinosaurs and within all three dinosaurian subclades (Ornithischia, Sauropodomorpha, and Theropoda), where speciation rate slowed down through time and was ultimately exceeded by extinction rate tens of millions of years before the K-Pg boundary. The only exceptions to this general pattern are the morphologically specialized herbivores, the Hadrosauriformes and Ceratopsidae, which show rapid species proliferations throughout the Late Cretaceous instead. Our results highlight that, despite some heterogeneity in speciation dynamics, dinosaurs showed a marked reduction in their ability to replace extinct species with new ones, making them vulnerable to extinction and unable to respond quickly to and recover from the final catastrophic event.

    Background There is very little literature regarding peripartum cardiomyopathy from the Asian countries. We conducted this study to determine demographic details, clinical presentations, complications and recovery of left ventricular (LV) systolic function in peripartum cardiomyopathy (PPCMP) patients of Pakistani origin. Method A ten year retrospective case series of PPCMP was conducted at the Aga Khan University Hospital. Patients were also followed up for six months after presentation, with special regard to improvement in the LV function. Results Total 45 patients were included, 25 (55.5%) primigravida and 8 (17.7%) gravida 2 and the remaining 12 (26.6%) were multigravida. Fourteen patients (31.1%) presented during pregnancy and 31 (68.8%) after delivery. All patients presented with CHF and three (6.6%) were complicated with ventricular tachycardia (VT) at presentation. LV systolic dysfunction was present in 39 (86.66%) patients and RV dysfunction in 15 (33.3%) patients. Two patients had LV clot and thromboembolic stroke occurred in another 4 patients. All patients received standard treatment except three patients who had asthma and could not be given beta blockers. Echocardiogram was repeated after 6 month and in 32 (71.1%) patients LV functions recovered to normal. RV function improved in all except 2 (4.4%) patients. All patients were discharged in stable condition. Conclusion Significant numbers of PPCMP patients, who had severe LV dysfunction at presentation recovered their LV functions at six month follow up.

    As the number and size of geoscience datasets persist in their constant rise, geoscientists increasingly express their yearning for further sharing of their data and software, and for facilitation of the associated academic credits. We present here our experience based on the open source development of an Earth System Model focusing on the propagation of water flow waves in large river networks: the Routing Application for Parallel computatIon of Discharge (RAPID). Since inception of RAPID ten years ago in January 2006, the community of its users has grown slowly but steadily, and now includes researchers in industry, academia, and government organizations. This growth of the RAPID users community can be explained - at least in part - by its open availability. However, despite an increasing support for open science (software and data), the mechanics of sharing still remain mysterious to many geoscientists… as they were for the authors. The purpose of this presentation is therefore to shed light on the steps involved in opening software and data based on a decade of experience related to the development and release of an Earth System Model. Three distinct steps of open sourcing are highlighted here: opening, exposing, and automatic testing. Each one of these steps is presented as an independent and tractable increment at various stages of development that is justified based on the size of the users community. Topics covered include software and data licenses, code and data repositories, unit testing, and continuous integration.

    Whether dinosaurs were in a long-term decline or whether they were reigning strong right up to their final disappearance at the Cretaceous-Paleogene (K-Pg) mass extinction event 66 Mya has been debated for decades with no clear resolution. The dispute has continued unresolved because of a lack of statistical rigor and appropriate evolutionary framework. Here, for the first time to our knowledge, we apply a Bayesian phylogenetic approach to model the evolutionary dynamics of speciation and extinction through time in Mesozoic dinosaurs, properly taking account of previously ignored statistical violations. We find overwhelming support for a long-term decline across all dinosaurs and within all three dinosaurian subclades (Ornithischia, Sauropodomorpha, and Theropoda), where speciation rate slowed down through time and was ultimately exceeded by extinction rate tens of millions of years before the K-Pg boundary. The only exceptions to this general pattern are the morphologically specialized herbivores, the Hadrosauriformes and Ceratopsidae, which show rapid species proliferations throughout the Late Cretaceous instead. Our results highlight that, despite some heterogeneity in speciation dynamics, dinosaurs showed a marked reduction in their ability to replace extinct species with new ones, making them vulnerable to extinction and unable to respond quickly to and recover from the final catastrophic event.

    The Third International Conference on Arctic Research Planning (ICARP III) provides a framework to identify Arctic science priorities for the next decade, to coordinate various Arctic research agendas, to inform policy makers, people who live in or near the Arctic and the global community and to build constructive relationships between producers and users of knowledge. The permafrost community, through the International Permafrost Association, has assembled a core team to coordinate ICARPIII activities. The team has the mandate to produce a short overview of permafrost research priorities for the next ten years based on input from the community. The IPA specifically mandated the group not to limit its focus to the Arctic but to define research priorities for the whole of permafrost research. Ultimately, engaging all partners, including funders, in shaping the future of research needs, ICARP III will produce a consensus statement identifying the most important Arctic research needs for the next decade and provide a roadmap for research priorities and partnerships. ICARP III is governed by a Steering Committee established by the participating organizations. It will be structured along scientific themes and include a series of events, culminating in a final conference at the Arctic Science Summit Week 2015. The permafrost community will engage its members over the year 2014 to produce a statement specific to permafrost research feeding into this process. In this presentation we highlight the progress made to date in the permafrost community to implement ICARPIII activities and pave the way to the the events to take place at the Arctic Science Summit Week 2015.

    In 2000, the Pacific Islands Families Study (PIFS) initiated research into developmental pathways of health outcomes for Pacific children and families. Not only was the study premised on addressing the gap in longitudinal research of Pacific peoples, it also aimed to increase Pacific-researcher capacity. After ten years of operation, this paper reviews the journal publications and Pacific authorship from the PIFS. The PIFS team published 55 journal articles in 29 peer reviewed journals. Forty-four (80.0%) of these articles had a Pacific author, including seven (12.7%) where the first-author was Pacific. Most articles used cross-sectional data (n = 38, 69.1%) and a quarter used longitudinal data (n = 15, 27.3%). Eighteen (62.1%) of the 29 journals that PIFS articles were published in were registered on the Journal Citations Report database, with 2009 5-year journal impact factors ranging from 1.064 to 6.504. The PIFS achieved a similar number of publications compared with the Dunedin Multidisciplinary Health and Development Study (DMHDS, n = 48) and Christchurch Health and Development Study (CHDS, n = 67). Further analysis, showed that the PIFS (27.3%) had the lowest proportion of publications using longitudinal data compared to the DMHDS (n = 37.5%) and CHDS (65.7%). This review provides a stocktake of publications in the first decade of the PIFS and shows that although the development of Pacific-researcher capacity has been promising, greater attention must be given to increasing first-authorship of academic writing and to utilising longitudinal data to better understand the origins of health status of Pacific peoples.

    Following trends of the pioneer PEPP project in USA, an European group has investigated since 1994 how to promote physics and earth sciences and, more specifically, how to educate scientifically and socially young generations to environmental hazards. Seismology has been selected as the vehicle for a prototypical ten-years experience of teaching and learning sciences in European high schools accounting for the specificity and differencies of educational systems in each country. This general purpose has required competences and strong interactions of both teachers, researchers and high school students. Over ten years of continuous activities, these people have found that the target was very ambitious and that both high-tech efforts as well as very focused teaching procedures must be set on. Dedicated instruments were developped in two years through interactions between researchers,teachers and students in order to fit both the scientific quality but also pedagogical features and were installed in different parts of Europe. The sequence of Colfiorito Earthquakes in September-October 1997 was the first data collected simultaneously in different European schools. Since then, more thant 50 stations have been deployed over Europe and data have been made available for education purposes. Data from these seismic stations have been used as the back-bone for interactions between students/pupils, teachers and researchers leading to the development of dedicated teaching and learning materials as software tools for data analysis, simple experimentations and so on. The framework for such an European initiative has been provided by Italian and French national funds and put together under the banner of the so-called EDUSEIS projet. This EDUcational SEISmological European Network (http://www.eduseis.org/) has shown that indeed environmental education is possible with its typical feature of long-term efforts. Funding through Europe will certainly increase the cohesion of this

    An alternative to determine the latent heat flux, which is the amount of energy available for evapotranspiration, is the use of data obtained by remote sensing. Among the models that use these data, the Surface Energy Balance Algorithm for Land - SEBAL (Bastiaanssen et al., 1998) has been increasing and has become widely used because it determines the evapotranspiration from the bullet full of radiation and energy on the surface land, using remote sensing data and a few additional data collected by surface weather station, as wind speed and temperature. This study aimed to evaluate the spatial variability of the latent heat flux according to the change of use and land cover. Thus, the algorithm was used to determine the SEBAL latent heat flux rate defined as the latent heat transferred from the surface due to the evaporation process or obtained by simple evaporation difference between the radiation balance, the heat flow in the soil and latent heat flux: (λET=RN-G-H). Where the value of the latent heat instantaneous flow, ie., its value at the time of satellite passage. To determine the latent heat flux were used Landsat 5 TM orbit and point 231/068 the following dates: 06/08/1999, 11/08/2001, 13/07/2005 and 09/08/2009.The study area is located in the central region of the Rondonia state in the Brazilian Amazon. This region has undergone an accelerated process of land use and soil in the last 30 years, which caused significant replacement of forest areas for other classes land use practices, mainly as grazing and agriculture.The results show that the area where the latent heat flux was greater decreased over ten years in analysis due to reduction of forest areas (Figure 1).These results show the latent heat flux in Rondônia in a very dry period, which is in July and August. Due to the long drought period, the topsoil dries faster and areas that are covered by pastures and agriculture have lower evapotranspiration values due to the root system are smaller and do

    2013-01-01

    Background Minimal invasive adrenalectomy has become the procedure of choice to treat adrenal tumors with a benign appearance, ≤ 6 cm in diameter and weighing < 100 g. Authors evaluated medium- and long-term outcomes of laparoscopic adrenalectomy (LA), performed for ten years in a single endocrine surgery unit. Methods We retrospectively reviewed 88 consecutive patients undergone LA for lesions of adrenal glands from 2003 to 2013. The first 30 operations were considered part of the learning curve. Doxazosin was preoperatively administered in case of pheochromocytoma (PCC), while spironolactone and potassium were employed to treat Conn's disease. Perioperative cardiovascular status modifications and surgical and medium- and long-term results were analyzed. Results Forty nine (55.68%) functioning tumors, and one (1.13%) bilateral adrenal disease were identified. In 2 patients (2.27%) a supposed adrenal metastasis was postoperatively confirmed, while in no patients a diagnosis of incidental primitive malignancy was performed. There was no mortality or major post operative complication. The mean operative time was higher during the learning curve. Conversion and morbidity rates were respectively 1.13% and 5.7%. Intraoperative hypertensive crises (≥180/90 mmHg) were observed in 23.5% (4/17) of PCC patients and were treated pharmacologically with no aftermath. There was no influence of age, size and operative time on the occurrence of PCC intraoperative hypertensive episodes. Surgery determined a normalization of the endocrine profile. One single PCC persistence was observed, while in a Conn's patient, just undergone right LA, a left sparing adrenalectomy was performed for a contralateral metachronous aldosteronoma. Conclusions LA, a safe, effective and well tolerated procedure for the treatment of adrenal neoplasms ≤ 6 cm, is feasible for larger lesions, with a similar low morbidity rate. Operative time has improved along with the increase of the experience and of

    The Global Threat Reduction Initiative's (GTRI) Offsite Source Recovery Project (OSRP) has been recovering excess and unwanted radioactive sealed sources for ten years. In January 2009, GTRI announced that the project had recovered 20,000 sealed radioactive sources (this number has since increased to more than 23,000). This project grew out of early efforts at Los Alamos National Laboratory (LANL) to recover and disposition excess Plutonium-239 (Pu-239) sealed sources that were distributed in the 1960s and 1970s under the Atoms for Peace Program. Decades later, these sources began to exceed their special form certifications or fall out of regular use. As OSRP has collected and stored sealed sources, initially using 'No Path Forward' waste exemptions for storage within the Department of Energy (DOE) complex, it has consistently worked to create disposal pathways for the material it has recovered. The project was initially restricted to recovering sealed sources that would meet the definition of Greater-than-Class-C (GTCC) low-level radioactive waste, assisting DOE in meeting its obligations under the Low-level Radioactive Waste Policy Act Amendments (PL 99-240) to provide disposal for this type of waste. After being transferred from DOE-Environmental Management (EM) to the U.S. National Nuclear Security Administration (NNSA) to be part of GTRI, OSRP's mission was expanded to include not only material that would be classified as GTCC when it became waste, but also any other materials that might constitute a 'national security consideration.' It was recognized at the time that the GTCC category was a waste designation having to do with environmental consequence, rather than the threat posed by deliberate or accidental misuse. The project faces barriers to recovery in many areas, but disposal continues to be one of the more difficult to overcome. This paper discusses OSRP's disposal efforts over its 10-year history. For sources meeting the DOE definition of

  18. Unjamming and jamming transitions of granular avalanches

    Study of the jamming transitions of granular materials has become an active field of research in recent years. A closely related inverse process is the unjamming transition, where granular systems may suddenly lose rigidity and start to flow freely. Understanding such a process is of crucial implication towards the understanding of natural disasters such as snow avalanches, landslides and earthquakes. Recent work by Banigan and colleagues (Nature Physics 2013) has provided a new perspective in the study of unjamming and jamming transitions by applying nonlinear dynamical methods. To test their proposition experimentally, we have designed a rotating drum filled with bidisperse photo-elastic disks to create particle avalanches. In unjamming transition, Lyapunov vector and velocity fields are indeed strongly correlated in spatial domain, whereas in jamming transition no such a strong correlation is observed. The Lyapunov exponents are positive in unjamming transition and negative in jamming transition. In addition, the total stress variation, kinetic energy, and non-affine motion of particles all show strong correlations in the time domain during avalanches. Their spatial correlations have also been analyzed.

    During the ten years from 1980 to 1989 inclusive, a total of 468 (16.1%) tumors were found in 2,907 pathological samples from domestic animals, collected from Southern Kyushu, around Miyazaki City. In this study, canine tumors were collected most commonly (340/468 cases, 73%). In small animals, the skin and mammary gland were associated particularly with tumorigenetic hazards. In cattle, high incidence of leukemia and mesothelioma was found. These tendencies were almost the same as those we reported for the preceding ten-year period, although the number of cases of tumor was higher in this study.

  20. Ten Years of Monitoring the Eruption of Shrub Mud Volcano, Alaska

    Shrub mud volcano, one of three in the Klawasi group on the eastern flank of Mount Drum volcano in the Wrangell volcanic field of eastern Alaska, has been erupting warm, saline mud and CO2-rich gas continuously since at least the summer of 1997, following 40 years of repose. The initial eruption in early summer of 1997, documented by Richter and others (1998), involved violent fountaining of mud, up to 6-8 m high, from nearly a dozen vents located near the summit, and quiet effusion from vents located about mid-way down the north flank of the 100-m-high cone. Guided by topography, early emissions of copious amounts of CO2 gas flowed in narrow streams through brushy foliage leaving behind stripes of brown, dead vegetation along the flow paths. The hazard posed by the CO2 emissions was evident from dead birds and mammals found near the vents. Initial surveys of the activity in 1997 recorded water temperatures up to 46°C. A survey in 1999 by Sorey and others (2000) found numerous active vents-many in different locations than those two years earlier-a maximum water temperature of 54°C, and an estimated total discharge of warm water of 50 l/s. Measured CO2 emissions were extrapolated to a discharge rate of 6-12 tonnes/day. The highest water temperature recorded was 57.3°C in 2000, with temperatures gradually declining since. From year to year, we found that eruptive activity migrated amongst clusters of vents, some new and some continuing from 1997. Between the summer of 2003 and the spring of 2004, the system changed dramatically when a large collapse pit formed a few tens of meters from the main summit vents and all previously active vents became inactive. This water-filled circular pit measured 28 m in diameter, up to 9 m deep, and encompassed an area that had previously been unaffected by the eruptive activity. In July 2004, water temperature and discharge at the outlet channel was 37.2°C and 9.4 l/s, respectively. The total CO2 discharge from the roiling pool

    Objectives To estimate mortality rates and prognostic factors in HIV-positive patients who started combination antiretroviral therapy between 1996–1999 and survived for more than ten years. Methods We used data from 18 European and North American HIV cohort studies contributing to the Antiretroviral Therapy Cohort Collaboration. We followed up patients from ten years after start of combination antiretroviral therapy. We estimated overall and cause-specific mortality rate ratios for age, sex, transmission through injection drug use, AIDS, CD4 count and HIV-1 RNA. Results During 50,593 person years 656/13,011 (5%) patients died. Older age, male sex, injecting drug use transmission, AIDS, and low CD4 count and detectable viral replication ten years after starting combination antiretroviral therapy were associated with higher subsequent mortality. CD4 count at ART start did not predict mortality in models adjusted for patient characteristics ten years after start of antiretroviral therapy. The most frequent causes of death (among 340 classified) were non-AIDS cancer, AIDS, cardiovascular, and liver-related disease. Older age was strongly associated with cardiovascular mortality, injecting drug use transmission with non-AIDS infection and liver-related mortality, and low CD4 and detectable viral replication ten years after starting antiretroviral therapy with AIDS mortality. Five-year mortality risk was <5% in 60% of all patients, and in 30% of those aged over 60 years. Conclusions Viral replication, lower CD4 count, prior AIDS, and transmission via injecting drug use continue to predict higher all-cause and AIDS-related mortality in patients treated with combination antiretroviral therapy for over a decade. Deaths from AIDS and non-AIDS infection are less frequent than deaths from other non-AIDS causes. PMID:27525413

Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical

    2010-12-01

    The next ten years have been described by influential science and policy figures as ‘the most important in human history’. Many believe that the actions taken will decide whether we catastrophically change the atmosphere and eradicate our fellow species or find an alternative, less-damaging development path. But communications and public engagement initiatives have tended to focus on near term impacts or debates - whether they emphasise hazards, or trumpet ‘solutions’. There are signs of diminishing returns on communications and public engagement efforts, and serious obstacles to engaging around 40% of publics in e.g. the US and the UK. The Creative Climate web project takes a new approach, inviting people to see humanity’s intellectual and practical journey with these issues as an inspiring, dynamic and unfolding story. We are inviting people to join us in building a huge living archive of experiences and ideas that respond to these issues. The website will collect thoughts and stories from doorstep to workplace, from lab to garden; from international conference to community meeting - from all over the world. The body of diaries lie at the core of the project, but these are supplemented by the offer of free online learning resources and broadcast-quality audio and video materials. The project is experimental in terms of its scope, its approach to environmental communications and debate and in its use of media. It works with formal partners, including the BBC, yet also makes the most of the opportunities for user generated content to create a rich multimedia resource that can support research, learning and engagement. The design of the project is informed by environmental social science and communications research, and by an awareness of the unfolding potential of Internet based communications to support social change. It is also intended that the Creative Climate platform will develop so as to serve researchers by offering an open resource of qualitative

    The U.S. Geological Survey collected stream discharge, stage, salinity, and water-temperature data near the mouths of 11 tributaries flowing into the Ten Thousand Islands area of Florida from October 2004 to June 2005. Maximum positive discharge from Barron River and Faka Union River was 6,000 and 3,200 ft3/s, respectively; no other tributary exceeded 2,600 ft3/s. Salinity variation was greatest at Barron River and Faka Union River, ranging from 2 to 37 ppt, and from 3 to 34 ppt, respectively. Salinity maximums were greatest at Wood River and Little Wood River, each exceeding 40 ppt. All data were collected prior to the commencement of the Picayune Strand Restoration Project, which is designed to establish a more natural flow regime to the tributaries of the Ten Thousand Islands area.

    Large wood governs channel morphology and determines the quality and distribution of aquatic habitat in many forested river networks. This is particularly true in streams that contain both key pieces large enough to form morphologically effective jams, as well as smaller mobile wood. In these streams, jams create spawning habitat by retaining sediment, increase rearing and over-wintering habitat by forming pools, and force avulsions which create side channels. To explore the effects of wildfire-induced increases in wood loading on channel morphology and aquatic habitat we have applied the stochastic reach-scale channel simulator (RSCS) to a case study of Fishtrap Creek, an intermediate-sized stream in the interior of British Columbia which experienced a high intensity fire in 2003. As predicted by model simulations, high quality spawning, rearing, and over-wintering habitats, as well as multi-thread channels, are found exclusively in association with wood, while plane-bed morphologies dominate where wood is absent. However, valley confinement and glacial legacy exert an important control on the magnitude of the impacts of the fire-derived wood; where the stream is confined, wood is suspended and morphologically ineffective, while un-confined segments contain high effective wood loads, multi-thread channels, and abundant aquatic habitat. These findings suggest that the morphologic effects of wood are highly dependent on valley geometry, which is in turn dictated by glacial legacy throughout much of North America, and that the impacts of valley confinement on the effectiveness of introduced wood must be considered in future model iterations. Plane bed morphology typical of reaches without large wood present Complex forced pool-riffle morphology typical of reaches with high wood loading

    Objective: The purpose of this study was to determine if oxidized zirconium femoral components had better outcomes than cobalt-chromium in vivo at medium and long term and if the use of oxidized zirconium components had clinical adverse effects. Methods: Forty consecutive patients (eighty knees) underwent simultaneous bilateral cruciate-retaining total knee arthroplasty for primary osteoarthritis from January 2002 to December 2003. For each patient, the knees were randomized to receive the oxidized zirconium femoral component, with the contralateral knee receiving the cobalt-chromium component. Outcome measures included the Western Ontario and McMaster Universities Osteoarthritis Index, Knee Injury and Osteoarthritis Outcome Score, Knee Society score, and British Orthopaedic Association patient satisfaction scale. Radiographic outcomes include the Knee Society total knee arthroplasty roentgenographic evaluation and scoring system and measurement of radiographic wear. Patients and assessors were blinded to the treatment groups and results. Results: There were no significant differences in clinical, subjective, and radiographic outcomes between the two implants at ten years postoperatively. Ten years following surgery, 36% of the patients preferred the cobalt-chromium knee compared with 11% who preferred the oxidized zirconium knee (p = 0.02) and 53% had no preference. Conclusions: Ten-year outcomes after total knee arthroplasty with oxidized zirconium and cobalt-chromium femoral components showed no significant differences in clinical, subjective, and radiographic outcomes. Patients had no preference or preferred the cobalt chromium prosthesis to the oxidized zirconium prosthesis. There were no adverse effects associated with the use of oxidized zirconium femoral implants.

    2016-04-01

    We study a well known neural network model—the perceptron—as a simple statistical physics model of jamming of hard objects. We exhibit two regimes: (1) a convex optimization regime where jamming is hypostatic and non-critical; (2) a non-convex optimization regime where jamming is isostatic and critical. We characterize the critical jamming phase through exponents describing the distribution laws of forces and gaps. Surprisingly we find that these exponents coincide with the corresponding ones recently computed in high dimensional hard spheres. In addition, modifying the perceptron to a random linear programming problem, we show that isostaticity is not a sufficient condition for singular force and gap distributions. For that, fragmentation of the space of solutions (replica symmetry breaking) appears to be a crucial ingredient. We hypothesize universality for a large class of non-convex constrained satisfaction problems with continuous variables.

  14. Tiger moth jams bat sonar.

    In response to sonar-guided attacking bats, some tiger moths make ultrasonic clicks of their own. The lepidopteran sounds have previously been shown to alert bats to some moths' toxic chemistry and also to startle bats unaccustomed to sonic prey. The moth sounds could also interfere with, or "jam," bat sonar, but evidence for such jamming has been inconclusive. Using ultrasonic recording and high-speed infrared videography of bat-moth interactions, we show that the palatable tiger moth Bertholdia trigona defends against attacking big brown bats (Eptesicus fuscus) using ultrasonic clicks that jam bat sonar. Sonar jamming extends the defensive repertoire available to prey in the long-standing evolutionary arms race between bats and insects.

    1. Harmonia axyridis was first recorded in Britain in 2004. Two subsequent earlier records were received from 2003. 2. The UK Ladybird Survey, a citizen science initiative involving online recording, was launched in 2005 to encourage people across Britain to track the spread of H. axyridis. Tens of thousands of people have provided records of H. axyridis and other species of ladybirds, creating an invaluable dataset for large-scale and long-term research. Declines in the distribution of seven (of eight assessed) native species of ladybird have been demonstrated, and correlated with the arrival of H. axyridis, using the records collated through the UK Ladybird Survey. 3. Experimental research and field surveys have also contributed to our understanding of the ecology of H. axyridis and particularly the process of invasion. Harmonia axyridis arrived in Britain through dispersal and introduction events from regions in which it was deliberately released as a biological control agent. The rapid spread of this species has been attributed to its high natural dispersal capability by means of both flight and anthropogenic transport. A number of factors have contributed to the successful establishment and indeed dominance of this polymorphic species within aphidophagous guilds, including high reproductive capacity, intra-guild predation, eurytopic nature, high resistance to natural enemies within the invaded range, and potentially phenotypic plasticity. 4. The global invasion by H. axyridis and subsequent research on this species has contributed to the general understanding of biological invasions. PMID:26435571

  17. The lack of technical basis for requiring a ten thousand year prediction for nuclear waste management

    1993-11-10

    There is no technical basis for setting a time limit of 10,000 years on the regulated performance of a nuclear waste repository. First, accurate prediction of releases for such periods is not possible. Second, there is nothing unique about 10,000 years. Third, equally toxic materials, which never transform to non-toxic substances by radioactive decay, have no long-term requirements. And fourth, over a 10,000 year time frame, social and natural disasters will dwarf the worst possible outcomes of repository placement. Analyses could be required to extend as long as doses above current radiation protection guidelines are possible (perhaps several million years), but these results should be recognized as qualitative information rather than evidence of quantitative compliance with exact numerical limits. Concern for what will happen over long times can be addressed for the next several hundred years by maintaining waste retrievability. At that time, uncertainty about future performance should have been reduced significantly.

    Diffusive transport in jammed particle packs is of interest for a number of applications, as well as being a potential indicator of structural properties near the jamming point. To this end, we report stochastic simulations of equilibrium diffusion through monodisperse sphere packs near the jamming point in the limit of a perfectly insulating surrounding medium. The time dependence of various diffusion properties is resolved over several orders of magnitude. Two time regimes of expected Fickian diffusion are observed, separated by an intermediate regime of anomalous diffusion. This intermediate regime grows as the particle volume fraction approaches the critical jamming transition. The diffusion behavior is fully controlled by the extent of the contacts between neighboring particles, which in turn depend on proximity to the jamming point. In particular, the mean first passage time associated with the escape of random walkers between neighboring particles is shown to control both the time to recover Fickian diffusion and the long time diffusivity. Scaling laws are established that relate these quantities to the difference between the actual and critical jamming volume fractions.

    2002-01-01

    Between November 1970 and September 1984 the senior author performed fifty-three consecutive total hip arthroplasties with cement in forty-one patients with the diagnosis of osteonecrosis of the femoral head. Five hips in three patients with failed renal transplants requiring chronic hemodialysis were excluded. At the time of final review, a minimum of ten years after the procedure, twenty-one patients (twenty-eight hips) were living, fifteen patients (eighteen hips) had died, and two patients (two hips) were lost to followup. A minimum ten-year follow-up radiograph was obtained on twenty-two (79%) of the hips in surviving patients. During the follow-up period 17.4% of hips (eight hips) required revision: 3.0% (six hips) for aseptic loosening, 2.2% (one hip) for sepsis, and 2.2% (one hip) for recurrent dislocation. All eight revisions occurred in patients living at time of final review, giving a revision prevalence of 22.9% (17.1% for aseptic loosening, 2.9% for sepsis, and 2.9% for recurrent dislocation) in patients surviving ten years. The prevalence of revision of the femoral component for aseptic loosening was 6.5% (three hips) for all hips and 9.1% (three hips) in patients surviving at least ten years. The prevalence of femoral aseptic loosening, defined as those components revised for aseptic loosening and those that demonstrated definite or probable radiographic loosening, was 13.0% (six hips) for all hips and 28.6% (six hips) for hips with at least ten-year radiographic follow-up. The prevalence of revision of the acetabular component for aseptic loosening was 13.0% (six hips) for all hips and 18.2% (six hips) in patients surviving at least ten years. The prevalence of acetabular aseptic loosening was 15.2% (seven hips) for all hips and 29.2% (seven hips) for hips with at least ten-year radiographic follow-up. In patients with osteonecrosis of the femoral head survivorship was significantly inferior to that in the senior author's overall patient population

    The long-term prediction of geomagnetic indices that characterize the state of the magnetosphere is discussed. While a prediction of the yearly average sunspot number is simultaneously a prediction of the yearly number of sudden-commencement storms, it is not a prediction of the number of disturbed or quiet half days. Knowledge of the sunspot cycle phase leads to a good estimate of the correlation expected between activity during one 27-day solar rotation period and the next.

    In 10 years 24 patients had a volar plate advancement arthroplasty for acute or chronic fracture dislocations of the proximal interphalangal joint. Seven were done within 6 weeks of injury, 17 at 6 weeks to 2 years following injury. Final ranges of motion averaged 95 degrees for the former and 78 degrees for the latter group. Radiographs frequently demonstrated a marked remodeling of the disrupted contour of the joint surface of the middle phalanx.

    Background Scarce information on outcomes of epidemic post infectious glomerulonephritis is available. This is a 10-year follow-up of the patients that developed acute glomerulonephritis in an epidemic outbreak caused by group C Streptococcus zooepidemicus in Brazil in 1998, that were also previously evaluated 2 and 5 years after the acute episode. Methods In this prospective study 60 cases (out of 134 in 1998) were reevaluated after 10 years, as well as community controls matched by gender and age. They underwent clinical and renal function evaluation, including serum creatinine and cystatin C, estimated glomerular filtration rate (eGFR), albuminuria and hematuria. Results Comparisons of clinical and renal function aspects of 60 patients and 48 community controls have not shown significant differences (eGFR <60 ml/min/1.73m2 and/or albuminuria >30mg/g creatinine: 13.8% vs. 12.2%, respectively, p = 0.817) except for a higher frequency of hypertension in the cases (45.0% vs. 20.8%, p = 0.009). Comparing the same patients affected in the acute episode, 2, 5 and 10 years later, it was observed an improvement of median eGFR levels at 2 years and a trend toward subsequent stabilization in these levels, associated with decrease in albuminuria and increased hypertension rates in the last survey. At 10 years it was not observed additional reduction of renal function using serum creatinine, eGFR and cystatin C. Conclusions During the acute episode of epidemic GN a considerable proportion of patients presented hypertension and reduced renal function; after 2 years and particularly at this 10-year follow-up survey there was no worsening of renal function parameters, except for persistent higher frequency of hypertension. Nevertheless, a longer follow up is necessary to confirm that progressive loss of renal function will not occur. PMID:25962068

  5. Ten years' experience using an integrated workers' compensation management system to control workers' compensation costs.

    This work presents 10 years of experience using an Integrated Workers' Compensation Claims Management System that allows safety professionals, adjusters, and selected medical and nursing providers to collaborate in a process of preventing accidents and expeditiously assessing, treating, and returning individuals to productive work. The hallmarks of the program involve patient advocacy and customer service, steerage of injured employees to a small network of physicians, close follow-up, and the continuous dialogue between parties regarding claims management. The integrated claims management system was instituted in fiscal year 1992 servicing a population of approximately 21,000 individuals. The system was periodically refined and by the 2002 fiscal year, 39,000 individuals were managed under this paradigm. The frequency of lost-time and medical claims rate decreased 73% (from 22 per 1000 employees to 6) and 61% (from 155 per 1000 employees to 61), respectively, between fiscal year 1992 and fiscal year 2002. The number of temporary/total days paid per 100 insureds decreased from 163 in fiscal year 1992 to 37 in fiscal year 2002, or 77%. Total workers' compensation expenses including all medical, indemnity and administrative, decreased from $0.81 per $100 of payroll in fiscal year 1992 to $0.37 per $100 of payroll in fiscal year 2002, a 54% decrease. More specifically, medical costs per $100 of payroll decreased 44% (from $0.27 to $0.15), temporary/total, 61% (from $0.18 to $0.07), permanent/partial, 63% (from $0.19 to $0.07) and administrative costs, 48% ($0.16 to $0.09). These data suggests that workers' compensation costs can be reduced over a multi-year period by using a small network of clinically skilled health care providers who address an individual workers' psychological, as well as physical needs and where communication between all parties (e.g., medical care providers, supervisors, and injured employees) is constantly maintained. Furthermore, these results

    Chest radiographs and spirometric tests were performed on 81 patients who had silicosis from two granite quarries in 1975, 73 of whom were followed up for two to 10 (mean 7.2) years. Each patient's initial and most recent chest radiographs were assessed independently by three experienced readers, and the yearly declines in forced expiratory volume in one second and forced vital capacity were estimated from two to four (mean 3.45) serial spirometric readings. Estimates of individual dust exposure were based on extensive historical data on hygiene. All but 11 patients were no longer exposed to dust by the start of follow up, but 24 (45%) of 53 patients who had simple silicosis and 11 (55%) of 20 who had the complicated disease showed radiological evidence of disease progression. In patients who had simple silicosis and showed no radiological progression the yearly declines in forced expiratory volume in one second and forced vital capacity were modest (64 ml/year and 59 ml/year, respectively), whereas significantly greater declines in lung function were seen in those who showed radiological evidence of progression (97 ml/year and 95 ml/year, respectively). In addition to radiological progression the previous average dust concentration to which patients had been exposed also influenced declines in both forced expiratory volume in one second and forced vital capacity after allowing for the effects of age, smoking, duration of exposure, history of tuberculosis, initial state of disease, and baseline lung function. The probability of radiological progression was most strongly influenced by the average dust concentration previously exposed to. The progression of simple silicosis is thus accompanied by appreciable declines in lung function and is strongly affected by previous levels of exposure to dust.

    A prospective study was undertaken to investigate the development of renal cell carcinoma in dialysis patients. Three renal cell carcinomas were detected among 96 hemodialysis patients in 1979, and screening by computed tomographic (CT) scan was continued yearly until 1989. During this 10-year period, one renal cell carcinoma was found in the second year and another in the ninth year. Autopsy performed on seven of 19 patients who died showed one case of small clear cell carcinoma accompanying acquired cystic disease. In 33 males, kidneys were found to have enlarged 2.7 +/- 1.7 times over the 10-year follow-up due to acquired cysts, while no change in kidney volume was noted in 24 females. Native kidneys in nine of 12 patients who maintained functioning grafts were reduced in size. The patient with the largest kidney enlargement (11.5 times) died from retroperitoneal bleeding in 1989. These prospective study results suggest that both the incidence and prevalence of renal cell carcinoma in dialysis patients is high. Furthermore, major complications of acquired renal cystic disease seem to occur predominantly in males.

    2015-02-01

    Altered fuels and climate change are transforming fire regimes in many of Earth's biomes. Postfire reassembly of vegetation--paramount to C storage and biodiversity conservation--frequently remains unpredictable and complicated by rapid global change. Using a unique data set of pre and long-term postfire data, combined with long-term data from nearby unburned areas, we examined 10 years of understory vegetation assembly after the 2002 Hayman Fire. This fire was the largest wildfire in recorded history in Colorado, USA. Resistance (initial postfire deviance from prefire condition) and resilience (return to prefire condition) declined with increasing fire severity. However, via both resistance and resilience, 'legacy' species of the prefire community constituted >75% of total plant cover within 3 years even in severely burned areas. Perseverance of legacy species, coupled with new colonizers, created a persistent increase in community species richness and cover over prefire levels. This was driven by a first-year increase (maintained over time) in forbs with short life spans; a 2-3-year delayed surge in long-lived forbs; and a consistent increase in graminoids through the 10th postfire year. Burning increased exotic plant invasion relative to prefire and unburned areas, but burned communities always were >89% native. This study informs debate in the literature regarding whether these increasingly large fires are 'ecological catastrophes.' Landscape-scale severe burning was catastrophic from a tree overstory perspective, but from an understory perspective, burning promoted rich and productive native understories, despite the entire 10-year postfire period receiving below-average precipitation.

    Over a period of 10 years, first-year students from 11 consecutive veterinary classes conducted a self-assessment using a natural abilities survey. The present study analyzes the data compiled from students' self-assessment results. As a group, veterinary students are exceptional problem solvers, either through inductive or deductive reasoning, and have strong spatial relations capacities. Veterinary students have a range of learning styles with design memory being the primary vehicle for information delivery and tonal memory being the least frequently used style overall. Information gained on each student's natural abilities can be used to guide effective career decision making and enhance prospects for long-term career satisfaction.

    The long term performance characteristics of the 2400 and 1260 series of Starr-Edwards aortic prostheses were investigated by a follow up study of clinical outcome of 327 patients discharged from hospital with isolated aortic valve replacement. Follow up lasted for up to 10 years and was based on 1616 patient-years. The 2400 series cloth covered tracked valve was implanted in 182 patients from 1974 to 1980 and the 1260 series bare strut silastic ball valve was inserted in 145 patients from 1979 to 1983. Total 10 year mortality and valve related morbidity were low and no cases of mechanical valve failure were recorded. There were no significant actuarial differences in mortality or valve related morbidity between the 2400 and 1260 valves. Starr-Edwards models 2400 and 1260 aortic valve prostheses showed excellent durability without any mechanical failures over a 10 year period. The long term outcome of isolated aortic valve replacement with these models is associated with a low frequency of valve related complications. PMID:3580223

    The long-term courses of people with schizophrenia and of those with substance use disorder have been studied separately and extensively. The long-term course of clients with co-occurring schizophrenic and substance use disorders has, however, not been examined. This article reports 10-year outcomes for 130 clients with co-occurring schizophrenic and substance use disorders in the New Hampshire Dual Diagnosis Study. In addition, we report on 6 "recovery outcomes," identified by dual diagnosis clients, as examples of positive coping behaviors. Longitudinal data were modeled using generalized estimating equation (GEE) methods. Participants improved steadily over 10 years in the outcome domains of symptoms, substance abuse, institutionalization, functional status, and quality of life. Further, at the 10-year follow-up, substantial proportions were above cutoffs selected by dual diagnosis clients as indicators of recovery: 62.7% were controlling symptoms of schizophrenia; 62.5% were actively attaining remissions from substance abuse; 56.8% were in independent living situations; 41.4% were competitively employed; 48.9% had regular social contacts with non-substance abusers; and 58.3% expressed overall life satisfaction. These 6 outcomes were only weakly interrelated over time, suggesting that recovery, as defined by clients, is a multidimensional concept. Overall, the 10-year findings on recovery outcomes provide a hopeful long-term perspective for dual diagnosis clients. PMID:16525088

  12. Ten years of hospitalisation for oral health-related conditions in Western Australia: an unjust dichotomy.

    PubMed

    Kruger, Estie; Tennant, Marc

    2016-01-01

    The objective of this study was: (1) to examine the demographics of in-patient oral health care by Aboriginal status; (2) to identify the mix of oral conditions by Aboriginal status; and (3) to describe trends over a 10-year period, comparing Aboriginal and non-Aboriginal groups. Hospitalisation data were obtained from the Western Australian Morbidity Data System (HMDS). The principal diagnosis, as classified by the International Classification of Disease (ICD-10AM), was obtained for every episode for adult patients who were discharged from all hospitals in Western Australia (WA) for the financial years 1999-2000 to 2008-09. Results indicated that more than 130000 persons were admitted to hospitals in WA over 10 years, for oral health-related conditions, at a direct cost of more than $400million. Most of those admitted were younger than 30 years, and 2.8% of all those admitted were Aboriginal people. Aboriginal people were admitted at significantly higher rates, for a very different mix of conditions, they were mostly from younger age groups, were mostly from very remote and the most disadvantaged areas and were almost all uninsured, compared with non-Aboriginal people. Hospital admissions for oral health-related conditions, as well as the mix of conditions that drive these hospitalisations, are strongly divided across social, racial and geographic variables, and remain a burden to the health-care system.

    2014-11-01

    Cassini’s findings have revolutionized our understanding of Saturn, its complex rings, the amazing assortment of moons and the planet’s dynamic magnetic environment. The robotic spacecraft arrived in 2004 after a 7-year flight from Earth, dropped a parachuted probe named Huygens to study the atmosphere and surface of Saturn’s big moon Titan, and commenced making astonishing discoveries that continue today. Icy jets shoot from the tiny moon Enceladus; Titan’s hydrocarbon lakes and seas are dominated by liquid ethane and methane, and complex pre-biotic chemicals form in the atmosphere and rain to the surface; 3-dimensional structures rise above Saturn’s rings, and a giant Saturn storm circled the entire planet. Cassini’s findings at Saturn have also fundamentally altered many of our concepts of how planets form around stars. The Solstice Mission continues to provide fundamental new science as Cassini observes seasonal and temporal changes, and addresses new questions that have arisen during the mission thus far. Cassini is now 4 years into its 7-year Solstice Mission. The mission’s grand finale occurs in 2017, with 22 inclined orbits between the innermost D ring and the upper portions of Saturn’s atmosphere, enabling unique gravity and magnetic field measurements of the planet, unprecedented determination of the ring mass, some of the highest resolution measurements of the rings and Saturn, and in situ observations in a completely new region around the planet. Highlights from 10 years of Cassini’s ambitious inquiry at Saturn will be presented along with the remarkable science that will be collected in the next three years.Cassini-Huygens is a cooperative undertaking by NASA, the European Space Agency (ESA), and the Italian space agency (Agenzia Spaziale Italiana, ASI).This work was carried out in part at the Jet Propulsion Laboratory, California Institute of Technology, under contract with NASA.

  20. Ten-year transient luminous events and Earth observations of FORMOSAT-2

    NASA Astrophysics Data System (ADS)

    Chern, Rock Jeng-Shing; Lin, Shin-Fa; Wu, An-Ming

    2015-07-01

    The purpose of this paper is to summarize the enormous contributions of FS2 (FORMOSAT-2 or Formosa satellite #2) in both Earth and transient luminous events (TLEs) observations in 10 years. As a small satellite operated for 10 years (20 May 2004 to 20 May 2014) in orbit, FS2 keeps its two unique characteristics: (1) to orbit 14 revolutions around the Earth per day with daily revisit capability, and (2) to provide the capabilities of Earth observation in sunlight time and TLEs observation in eclipsed time every day. It carries two payloads: the remote sensing instrument (RSI) for Earth imaging in satellite's day time and the imager of sprites and upper atmospheric lightning instrument (ISUAL) for scientific observations in satellite's night time, respectively. Daily revisit capability provides changes of events on Earth in either short time (several days) or long term (several years). Examples include: Indian Ocean earthquake and tsunami (December 2004), disintegration of Wilkins Ice Shelf in Antarctica region (2006-2014, long term), Sichuan earthquake (May 2008), Tohoku earthquake and tsunami (March 2011), polar regions (2006-2014, long term), etc. In the TLEs observation, ISUAL had recorded more than 35,000 events in 10 years with 73.93% elves, 6.54% red sprites, 5.81% halos, 13.42% blue jets and 0.30% gigantic jets. Major contributions of FS2 in this specific scientific area are presented. In particular, current and future research topics on TLEs are discussed. Also, major contributions of FS2's RSI to the United Nations Institute for Training and Research (UNITAR) Operational Satellite Applications Programme (UNOSAT) and Group of Earth Observation System of Systems (GEOSS) are summarized. This paper also addresses briefly the health status of FS2 after working 10 years in orbit.

    2007-01-01

    Objectives To evaluate the effectiveness of a problem-based learning (PBL) model implemented in 1995 at the University of Mississippi School of Pharmacy. Design The third-professional (P3) year curriculum was reoriented from a faculty-centered model of teaching to a student-centered model of learning. Didactic lectures and structured classroom time were diminished. Small student groups were organized and a faculty facilitator monitored each group's discussions and provided individual student assessments. At the end of each 8-week block, students were assessed on group participation, disease and drug content knowledge, and problem-solving abilities. Faculty and student input was solicited at the end of each year to aid programmatic improvement. In 2000, a formal 5-year review of the PBL program was conducted. Assessment Recommendations for improvement included clarifying course objectives, adopting a peer-review process for examination materials, refining the group assessment instruments, and providing an opportunity for student remediation after a course was failed. A weekly case conference presided over by a faculty content expert was also recommended. Ongoing critical evaluation during the following 5-year period was provided by graduates of the program, faculty participants, and accreditation reviews. Conclusion Over our 10-year experience with a PBL model of P3 education, we found that although the initial challenges of increased demands on personnel and teaching space were easily overcome, student acceptance of the program depended on their acknowledgment of the practical benefits of active learning and on the value afforded their input on curricular development.

    Purpose To assess the effect of donor and recipient factors on corneal allograft rejection and evaluate whether a rejection event was associated with graft failure. Methods 1,090 subjects undergoing penetrating keratoplasty for a moderate risk condition (principally Fuchs’ dystrophy or pseudophakic corneal edema) were followed for up to 12 years. Associations of baseline recipient and donor factors with the occurrence of a rejection event were assessed in univariate and multivariate proportional hazards models. Results Among 651 eyes with a surviving graft at 5 years, the 10-year graft failure (± 99% CI) rates were 12% ± 4% among eyes with no rejection events in the first 5 years, 17% ± 12% in eyes with at least one probable, but no definite rejection event, and 22% ± 20% in eyes with at least one definite rejection event. The only baseline factor significantly associated with a higher risk of definite graft rejection was a preoperative history of glaucoma, particularly when prior glaucoma surgery had been performed and glaucoma medications were being used at time of transplant (10-year incidence 35% ± 23% compared with 14% ± 4% in eyes with no history of glaucoma/intraocular pressure treatment, p=0.008). Conclusion Those patients who experienced a definite rejection event frequently went on to graft failure raising important questions as to how we might change acute and long-term corneal graft management. Multivariate analysis indicated that the prior use of glaucoma medications and glaucoma filtering surgery was a significant risk factor related to a definite rejection event. PMID:25119961

  3. Jamming in Granular Systems

    NASA Astrophysics Data System (ADS)

    Utter, Brian

    2008-10-01

    Granular materials exist all around us, from the formation of sand dunes and collapse of seemingly stable grain silos, to the mixing of pharmaceuticals and other industrial materials. The behavior of these ``fluids'' though poorly understood. Their flow can be characterized by the continuous forming and breaking of a strong force network resisting flow. This jamming/unjamming behavior is typical of a variety of systems, including granular flows, and is influenced by factors such as grain packing fraction, applied shear stress, and the random kinetic energy of the particles. We present experiments on quasi-static shear and free-surface granular flows under the influence of external vibrations. By using photoelastic grains, we are able to measure particle trajectories and the local force network in these 2D flows. We find that during shear, sufficient shaking weakens the strong force network and reduces the amount of flow driven by sidewalls. We vibrate either the driving wall (sidewall forcing) or the entire shearing zone (bulk forcing). For sidewall forcing, flow behavior is controlled by vibration amplitude in particular and slipping of force chains at the boundary. In a rotating drum geometry, we find that small vibration leads to strengthening of the pile while larger vibrations induce failure as might be expected. This behavior is strongly history dependent and sufficient vibration erases the memory of the pile.

  4. Ten-year experience with mission-based budgeting in the faculty of medicine of Dalhousie University.

    PubMed

    Ruedy, John; MacDonald, Noni E; MacDougall, Brian

    2003-11-01

    The Faculty of Medicine of Dalhousie University (the Faculty) has applied a mission-based approach to the allocation of the academic budget since 1993. Over the ensuing decade, large shifts in budgets to academic departments have been effected, and two goals that required special emphasis-the successful implementation of a tutorial-based undergraduate medical curriculum and an increase in research activity-have been achieved. This has occurred despite significant reductions in the overall academic budget over the ten-year period. The budgeting process provided the Faculty with a tangible means of supporting its mission and also gave each department a transparent report of its relative contribution to the overall mission of the Faculty, which helped instill pride. In some years, misunderstandings of the budget process arose because of confusion over the impact of the overall total academic budget reductions experienced by the Faculty in that year. This meant that recognition of a department's contribution resulted, in most instances, in a relatively smaller reduction in budget rather than a budget increase. Further misunderstandings have arisen because of confusion between mission-based and activity-based budgeting. This confusion was reinforced because the assessments of education outcomes were measurements of activity rather than of outcomes. However, these measures were chosen to be the best-available indirect measures of the desired educational outcome. After ten years, the fundamentals of the mission-based process introduced in 1993 remain unchanged as the basis for allocation of the academic budget for the Faculty.

  5. Ten Years and Counting: Moving Leucine-Rich Repeat Kinase 2 Inhibitors to the Clinic

    2015-01-01

    The burden that Parkinson's disease (PD) exacts on the population continues to increase year after year. Though refinement of symptomatic treatments continues at a reasonable pace, no accepted therapies are available to slow or prevent disease progression. The leucine-rich repeat kinase 2 (LRRK2) gene was identified in PD genetic studies and offers new hope for novel therapeutic approaches. The evidence linking LRRK2 kinase activity to PD susceptibility is presented, as well as seminal discoveries relevant to the prosecution of LRRK2 kinase inhibition. Finally, suggestions are made for predictive preclinical modeling and successful first-in-human trials. © 2014 The Authors.

    Alexander, William; Coghlan, Patrick; Greenwood, John

    2014-01-01

    Cement is extensively used both in the professional construction and "do-it-yourself" industries. Despite a number of small published series during the past 80 years highlighting its potential for harm, little seems to have been done to make consumers aware of its risks of causing serious burn injuries. The authors present 10 years of a tertiary adult burn center's experience with these burns, and highlight the significance of these burns on the active, working sector of society. Both professionals and part-time enthusiasts are affected, with burns of significant depth and subsequent impairment of normal functioning. The authors propose a better education system to highlight the risks and, in time, reduce the incidence of cement burns.

    Aim The aim of the present study was to analyze the age of breast cancer patients managed with curative approach at the time of treatment with radiotherapy. Background Breast cancer is the most frequent neoplasm in women. Little is known with regard to the age of patients at diagnosis, and some authors have suggested that breast cancer is now affecting women who are younger than before. Materials and methods We performed a descriptive study of our series of breast cancer patients from 1998 to 2011. The age of patients, city of residence, year of treatment and uni- or bilateral location were extracted from the administrative database of the Radiation Oncology Department. The demographical and reference populational data were extracted from the Catalan Institute of Statistics. Results 3382 patients were obtained. The mean age was 57.79 years. No statistical differences were observed in the mean age during the period of study (p > 0.05), nor in patients with bilateral neoplasias with regard to unilateral tumours (p > 0.5). Patients aged less than 30, 40, 50 and 65 years were 0.3%, 6.3%, 27.0% and 69.1%, respectively. The proportion of patients aged less, equal or more than 40 and 50 years was not statistically different. Conclusions Breast cancer patients treated with adjuvant radiotherapy after radical surgery have not experienced significant changes in their mean age at treatment. The subgroups of patients that remain out of the mammographic screening programmes were unchanged as well. The observed differences can be explained by demographical disparities and by a probable increase in the indications for adjuvant radiotherapy. PMID:25535580

    The nematode Caenorhabditis elegans is a central laboratory model system in almost all biological disciplines, yet its natural life history and population biology are largely unexplored. Such information is essential for in-depth understanding of the nematode's biology because its natural ecology provides the context, in which its traits and the underlying molecular mechanisms evolved. We characterized natural phenotypic and genetic variation among North German C. elegans isolates. We used the unique opportunity to compare samples collected 10 years apart from the same compost heap and additionally included recent samples for this and a second site, collected across a 1.5-year period. Our analysis revealed significant population genetic differentiation between locations, across the 10-year time period, but for only one location a trend across the shorter time frame. Significant variation was similarly found for phenotypic traits of likely importance in nature, such as choice behavior and population growth in the presence of pathogens or naturally associated bacteria. Phenotypic variation was significantly influenced by C. elegans genotype, time of isolation, and sampling site. The here studied C. elegans isolates may provide a valuable, genetically variable resource for future dissection of naturally relevant gene functions. PMID:26380661

  9. Ten-year-old children strategies in mental addition: A counting model account.

    PubMed

    Thevenot, Catherine; Barrouillet, Pierre; Castel, Caroline; Uittenhove, Kim

    2016-01-01

    For more than 30 years, it has been admitted that individuals from the age of 10 mainly retrieve the answer of simple additions from long-term memory, at least when the sum does not exceed 10. Nevertheless, recent studies challenge this assumption and suggest that expert adults use fast, compacted and unconscious procedures in order to solve very simple problems such as 3+2. If this is true, automated procedures should be rooted in earlier strategies and therefore observable in their non-compacted form in children. Thus, contrary to the dominant theoretical position, children's behaviors should not reflect retrieval. This is precisely what we observed in analyzing the responses times of a sample of 42 10-year-old children who solved additions with operands from 1 to 9. Our results converge towards the conclusion that 10-year-old children still use counting procedures in order to solve non-tie problems involving operands from 2 to 4. Moreover, these counting procedures are revealed whatever the expertise of children, who differ only in their speed of execution. Therefore and contrary to the dominant position in the literature according to which children's strategies evolve from counting to retrieval, the key change in development of mental addition solving appears to be a shift from slow to quick counting procedures.

    NonaSantfeliu study: A review is presented of the studies that are part of the initial overall assessment and the studies performed during the 10 years of follow-up of a cohort of nonagenarians. It is a population-based study of 186 subjects, 76.5% women, mean age at baseline of 93.06 years, a quarter (26%) being institutionalized. The mean of baseline Barthel index was 60.8, and the mean for the Lobo's cognitive minimental was 21. Nonagenarian males with low comorbidity had more successful aging criteria than women with high comorbidity quantified with the Charlson Index. The survival rate at 10 years follow-up was very low, and 95.6% of the population had died. This represented an annual mortality rate of 9.5%. A common denominator on assessing all different annual cuts, is that the most important factors associated with mortality are those related to geriatric assessment, such as a function, cognition, dementia, and cumulative comorbidity and multiple medications, compared to more traditional risk factors described in younger populations.

    In landscape reconstruction in an opencast coal mine, a gradient of slopes can be obtained. The slope gradient can affect different processes, such as plant growth, especially in semi-arid conditions. On the other hand, to favor the heterogeneity of habitats and ensure long-term restoration, late successional woody species have been planted but with heterogeneous results. In this study, the effect of a slope gradient (from 11.4 to 15.5 degrees) on the growth and survival of five Mediterranean woody species 10 years after the reconstruction of mining banks was evaluated. Slope gradient reduced height growth significantly from 10 cm degree{sup -1} (lentish) to 25 cm degree{sup -1} (pine) in 10-year- old woody species. This gradient also reduced basal diameter growth from 0.22 mm degree{sup -1} (juniper) to 0.58 mm degree{sup -1} (pine). Survival and slope were not significantly correlated. Growth and survival of the 10-year- old woody species were equal to or higher than those of the same species in other afforestations in semi-arid conditions. This outcome demonstrates the adequacy of species and applied techniques of restoration that allow a long-term reliability of reclaimed mine slopes.

    While deaths are thought to be rare in community Australian sport, there is no systematic reporting so the frequency and leading causes of death is unknown. The aim of this study was to describe the frequency and cause of deaths associated with community-level Australian Football (AF), based on insurance-claims records. Retrospective review of prospectively collected insurance-claims for death in relation to community-level AF activities Australia-wide from 2004 to 2013. Eligible participants were aged 15+ years, involved in an Australian football club as players, coaches, umpires or supporting roles. Details were extracted for: year of death, level of play, age, sex, anatomical location of injury, and a descriptive narrative of the event. Descriptive data are presented for frequency of cases by subgroups. From 26,749 insurance-claims relating to AF, 31 cases were in relation to a death. All fatalities were in males. The initial event occurred during on-field activities of players (football matches or training) in 16 cases. The remainder occurred to people outside of on-field football activity (n = 8), or non-players (n = 7). Road trauma (n = 8) and cardiac conditions (n = 7) were the leading identifiable causes, with unconfirmed and other causes (including collapsed or not yet determined) comprising 16 cases. Although rare, fatalities do occur in community AF to both players and people in supporting roles, averaging 3 per year in this setting alone. A systematic, comprehensive approach to data collection is urgently required to better understand the risk and causes of death in participants of AF and other sports. PMID:27467365

    The Cassini-Huygens mission has greatly enhanced our understanding of the Saturn system. Fundamental discoveries have altered our views of Saturn, its retinue of icy moons including Titan, the dynamic rings, and the system’s complex magnetosphere. Cassini has orbited Saturn for 10 years, delivering the Huygens probe to its Titan landing in 2005. It is now three years into its 7-year Solstice mission, returning science in a previously unobserved seasonal phase. As it watches the approach of northern summer, long-dark regions throughout the system become sunlit, allowing Cassini’s science instruments to probe as-yet unsolved mysteries. Key Cassini-Huygens discoveries include icy jets of material streaming from tiny Enceladus’ south pole, lakes of liquid hydrocarbons and methane rain on giant Titan, three-dimensional structures in Saturn’s rings, and curtain-like aurorae flickering over Saturn’s poles. The Huygens probe sent back amazing images of Titan’s surface, and made detailed measurements of the atmospheric composition, structure and winds. Key Cassini-Huygens science highlights will be presented. The Solstice Mission continues to provide new science as Cassini observes seasonal and temporal changes, and addresses new questions that have arisen during the mission thus far. The mission’s grand finale occurs in 2017, with 22 inclined orbits between the innermost D ring and the upper portions of Saturn’s atmosphere, enabling unique gravity and magnetic field measurements of the planet, unprecedented determination of the ring mass, some of the highest resolution measurements of the rings and Saturn, and in situ observations in a completely new region around the planet. Cassini-Huygens is a cooperative undertaking by NASA, the European Space Agency (ESA), and the Italian space agency (Agenzia Spaziale Italiana, ASI). This work was carried out in part at the Jet Propulsion Laboratory, California Institute of Technology, under contract with NASA

    An analysis is made of the UV Index (UVI) obtained from the ultraviolet erythemal solar radiation (UVER) data measured by the Spanish UVB Radiometric Network between the years 2000 and 2009. Previously, the daily UVI has been evaluated using two different criteria: (a) the value corresponding to solar noon; and (b) the daily maximum value. The mean percentage of agreement is 92% if we consider the cases for which the difference is zero or one UVI unit. These results are similar to those obtained in a previous work where only 2 years were analyzed. In all the stations the UVI reaches very high values (8-10) in spring-summer, and the very high and extreme (≥ 11) UVI values are more dependent on the continental effect than on the latitude effect. From the UVI values it is possible to classify the stations into four groups: Coastal stations, Continental stations (more than 200 km from the coast), Southern stations (Coastal stations but with similar values of UVI as the Continental ones due to their low latitude) and Canary Islands stations (1400 km southwest from the Iberian Peninsula thus lower latitude). The monthly mean maximum of UVI is reached in July due to the annual evolution of the total ozone column. This value corresponds, for a skin phototype II, to three times the minimal erythemal dose (MED) in an hour in a Coastal station, 3.5 MEDs in an hour measured in a Continental or Southern station and up five MEDs in an hour in the Izaña station (Canary Islands). The cumulative dose on a horizontal plane over an average year has been calculated for each station. More than 40% of the annual dose is received in summer, about 35% in spring, more than 11% in autumn and less than 10% in winter except for the stations in the Canary Islands where the difference between seasons is less significant.

    OBJECTIVE: Birth defects (BDs) are an important cause of infant mortality and disproportionately occur among low birth weight infants. We determined the prevalence of BDs in a cohort of very low birth weight (VLBW) infants cared for at the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network (NRN) centers over a 10-year period and examined the relationship between anomalies, neonatal outcomes, and surgical care. METHODS: Infant and maternal data were collected prospectively for infants weighing 401 to 1500 g at NRN sites between January 1, 1998, and December 31, 2007. Poisson regression models were used to compare risk of outcomes for infants with versus without BDs while adjusting for gestational age and other characteristics. RESULTS: A BD was present in 1776 (4.8%) of the 37 262 infants in our VLBW cohort. Yearly prevalence of BDs increased from 4.0% of infants born in 1998 to 5.6% in 2007, P < .001. Mean gestational age overall was 28 weeks, and mean birth weight was 1007 g. Infants with BDs were more mature but more likely to be small for gestational age compared with infants without BDs. Chromosomal and cardiovascular anomalies were most frequent with each occurring in 20% of affected infants. Mortality was higher among infants with BDs (49% vs 18%; adjusted relative risk: 3.66 [95% confidence interval: 3.41–3.92]; P < .001) and varied by diagnosis. Among those surviving >3 days, more infants with BDs underwent major surgery (48% vs 13%, P < .001). CONCLUSIONS: Prevalence of BDs increased during the 10 years studied. BDs remain an important cause of neonatal morbidity and mortality among VLBW infants. PMID:23733791

    A retrospective review of intestinal transplantation (ITx) at Seoul St. Mary's Hospital was made by collecting clinical data over the past 10 years. Fifteen consecutive cases from 2004 were analyzed. Five children and 10 adults (6 months to 69 years of age) were included. Primary diseases in adults included 4 mesenteric vessel thromboses, 2 strangulations, and 1 each of visceral myopathy, malignant gastrointestinal stromal tumor (GIST), mesenteric lymphangiectasis, and injury. Pediatric cases involved 2 Hirschsprung disease, 2 visceral myopathy, and 1 necrotizing enterocolitis. Three of 7 stomas were closed using a serial transverse enteroplasty procedure before transplantation. The ITx were performed using 3 living-donor Itx, 12 deceased-donor ITx, 14 isolated Itx, and 1 modified multivisceral transplantation. Daclizumab, basiliximab, alemtusumab, or basiliximab with rabbit antithymocyte globulin (rATG) was used for the induction; tacrolimus monotherapy was used as the basic maintenance immunosuppressant; and m-TOR inhibitor was used for renal dysfunction patients. Seven cases of acute cellular rejection were treated with rATG. Three cases of antibody-mediated rejection were treated with rituximab alone or with rituximab and bortezomib combination. There were 4 cases of early mortality within 6 months after Itx. Causes of death were declamping shock, cardiac tamponade with acute cellular rejection, dysmotility, and sepsis. Surgical complications consisted of 1 feeding jejunostomy displacement, and a minor leakage at a colo-colostomy site. One-year survival of the patient and graft was 73.33% (Kaplan-Meier survival curve). Although the total number of ITx is small, its social impact has been remarkable in changing the related laws and reimbursement policy in Korea. PMID:27109981

    INTRODUCTION New knowledge, and improved surgical hardware and fixation techniques have changed surgical management. We review the evolving trends of surgically managed proximal humerus fractures. METHODS Patients who underwent surgery for proximal humerus fractures from 1 January 2001 to 31 December 2010 were identified from the hospital’s electronic diagnosis and operative coding database. Data extracted from the database included patient demographics, comorbidities, clinical and radiological findings, operative techniques, and complications. RESULTS In total, 95 patients with 97 surgically managed proximal humerus fractures were identified. The median age of the patients was 50 (range 12–85) years, and the male to female ratio was 1.2:1.0. Male patients tended to present at a younger age than female patients (peak age 30–39 years vs. 70–79 years, p < 0.001). Two-part surgical neck fracture was the most common type of fracture (n = 33, 34.0%). Plate osteosynthesis was predominantly used for two- and three-part surgical neck fractures involving the greater tuberosity (p = 0.03, p = 0.0002, respectively). Hemiarthroplasty was commonly performed for four-part fractures (p < 0.001). Wound infections, implant failure, avascular necrosis of the humeral head and nonunion were seen in 8 (8.3%) cases. Minimally invasive plate osteosynthesis (MIPO) had been in use since 2007 (p < 0.001). CONCLUSION Surgically managed proximal humerus fractures predominantly involved young men following high velocity injury and elderly women following osteoporotic fractures. Open plating was most commonly used for two- and three-part fractures, and hemiarthroplasty for four-part fractures. MIPO techniques have been practised in our institution since 2007. PMID:25631967

    To celebrate the first 10 years of Nature Reviews Genetics, we asked eight leading researchers for their views on the key developments in genetics and genomics in the past decade and the prospects for the future. Their responses highlight the incredible changes that the field has seen, from the explosion of genomic data and the many possibilities it has opened up to the ability to reprogramme adult cells to pluripotency. The way ahead looks similarly exciting as we address questions such as how cells function as systems and how complex interactions among genetics, epigenetics and the environment combine to shape phenotypes.

    The Multi-angle Imaging SpectroRadiometer (MISR) instrument has been collecting global Earth data from NASA's Terra satellite since February 2000. With its nine along-track view angles, four visible/near-infrared spectral bands, intrinsic spatial resolution of 275 m, and stable radiometric and geometric calibration, no instrument that combines MISR's attributes has previously flown in space. The more than 10-year (and counting) MISR data record provides unprecedented opportunities for characterizing long-term trends in aerosol, cloud, and surface properties, and includes 3-D textural information conventionally thought to be accessible only to active sensors.

    Background Many observational studies have shown a protective effect of physical activity on cognitive ageing, but interventional studies have been less convincing. This may be due to short time scales of interventions, suboptimal interventional regimes or lack of lasting effect. Confounding through common genetic and developmental causes is also possible. Objectives We aimed to test whether muscle fitness (measured by leg power) could predict cognitive change in a healthy older population over a 10-year time interval, how this performed alongside other predictors of cognitive ageing, and whether this effect was confounded by factors shared by twins. In addition, we investigated whether differences in leg power were predictive of differences in brain structure and function after 12 years of follow-up in identical twin pairs. Methods A total of 324 healthy female twins (average age at baseline 55, range 43-73) performed the Cambridge Neuropsychological Test Automated Battery (CANTAB) at two time points 10 years apart. Linear regression modelling was used to assess the relationships between baseline leg power, physical activity and subsequent cognitive change, adjusting comprehensively for baseline covariates (including heart disease, diabetes, blood pressure, fasting blood glucose, lipids, diet, body habitus, smoking and alcohol habits, reading IQ, socioeconomic status and birthweight). A discordant twin approach was used to adjust for factors shared by twins. A subset of monozygotic pairs then underwent magnetic resonance imaging. The relationship between muscle fitness and brain structure and function was assessed using linear regression modelling and paired t tests. Results A striking protective relationship was found between muscle fitness (leg power) and both 10-year cognitive change [fully adjusted model standardised β-coefficient (Stdβ) = 0.174, p = 0.002] and subsequent total grey matter (Stdβ = 0.362, p = 0.005). These effects were robust in discordant

    Riparian ecosystems integrate aquatic and terrestrial communities and often contain unique assemblages of flora and fauna. Retention of forested buffers along riparian habitats is a commonly employed practice to reduce potential negative effects of land use on aquatic systems. However, very few studies have examined long-term population and community responses to buffers, leading to considerable uncertainty about effectiveness of this practice for achieving conservation and management outcomes. We examined short- (1-2 years) and long-term (~10 years) avian community responses (occupancy and abundance) to riparian buffer prescriptions to clearcut logging silvicultural practices in the Pacific Northwest USA. We used a Before-After-Control-Impact experimental approach and temporally replicated point counts analyzed within a Bayesian framework. Our experimental design consisted of forested control sites with no harvest, sites with relatively narrow (~13 m) forested buffers on each side of the stream, and sites with wider (~30 m) and more variable width unharvested buffer. Buffer treatments exhibited a 31-44% increase in mean species richness in the post-harvest years, a pattern most evident 10 years post-harvest. Post-harvest, species turnover was much higher on both treatments (63-74%) relative to the controls (29%). We did not find evidence of local extinction for any species but found strong evidence (no overlap in 95% credible intervals) for an increase in site occupancy on both Narrow (short-term: 7%; long-term 29%) and Wide buffers (short-term: 21%; long-term 93%) relative to controls after harvest. We did not find a treatment effect on total avian abundance. When assessing relationships between buffer width and site level abundance of four riparian specialists, we did not find strong evidence of reduced abundance in Narrow or Wide buffers. Silviculture regulations in this region dictate average buffer widths on small and large permanent streams that range from

    The psychology of extinction has been studied for decades. Approximately 10 years ago, however, there began a concerted effort to understand the neural circuits of extinction of fear conditioning, in both animals and humans. Progress during this period has been facilitated by an unusual degree of coordination between rodent and human researchers examining fear extinction. This successful research program could serve as a model for translational research in other areas of behavioral neuroscience. Here we review the major advances and highlight new approaches to understanding and exploiting fear extinction. PMID:22129456

    Cocaine is the second most consumed illegal drug in the western world, following cannabis. Since 1998, it is also the drug that more attendances generate in different emergency devices, and it is responsible for more of 60% of the emergencies directly related to drug consumption. This work reviews the main Spanish scientific articles published in the last 10 years, in which different factors related to the use of this drug have been analyzed in relation to the use of emergency by cocaine users. A total of 8,795 patients were included (interval 57-1,755), with an average age of 32.64 years (SD 3.02), and an average percentage of positives to cocaine of 54.78% (SD 47.03); there were 7 works with 100% of subjects being positive to cocaine. Males predominated with an average of 78.69% (SD 12). They presented cardiovascular symptoms in 30% cases (SD 22.7), neurological symptoms in 11.6% cases (SD 4.28) and psychiatric symptoms in 49.32% cases (SD 23.87). There was a multiple consumption in 49.02% of patients (interval 4.3-76.2), fundamentally associated with alcohol (57.78%, SD 6.18) and cannabis (21.56%, SD 10.72). Two hundred and forty-six patients (2.8%) needed admission and 8 died (0.09%). PMID:24461737

    In this brief paper, I review my 10 years as the Editor of the Philosophical Transactions of the Royal Society A. I look at the content of the journal over the years, relating it to a full classification of the physical sciences based on the interests of fellows and research fellows of the Royal Society. I show that the journal has performed well in terms of downloads, citations and impact factors. Innovations such as the Millennium and Christmas Issues for young scientists have stimulated a close and enjoyable interaction with the Society's research fellows. In addition to authoring papers and organizing themes, they have always been keen to help with the refereeing processes. They provided exciting demonstrations for a Summer Science exhibit that I organized to highlight the work of the journal, and five of the research fellows now sit on the Editorial Board. Looking to the future, I describe the new subject clusters that are being introduced as the journal steps up its publication rate from one issue per month to two, starting in January 2008.

    Women from families with an increased risk for breast/ovarian cancer have undergone bilateral prophylactic mastectomy (BPM) since the early 1990s at the Karolinska University Hospital in Sweden. Perceptions of BPM as reported by the first women who underwent the procedure have previously been evaluated on a short-term basis (1-3 years). The present study aims to evaluate the long-term (10 years) physical and psychological consequences of BPM in the same cohort of women. Some of the very first women to undergo BPM participated in the present interview study (n= 13). The semi-structured interviews focused on the women's long-term experiences related to BPM and immediate breast reconstruction. Overall, the women were satisfied with their decision to undergo BPM and perceived a negligible remaining risk of getting breast cancer. For most women, the operation had not resulted in changes in family life or lifestyle (n= 8), although some described that the relationship with their spouse was affected (8/13), either in a negative (n= 5) or positive (n= 3) way. The cosmetic results were mainly positive (n= 10). Recurrent counselling and support during the whole process of decision, treatment and follow up is recommended.

    We report here the symptoms of diphenylarsinic acid (DPAA) poisoning recorded over 10 years since the DPAA contamination of the potable well water was first detected in the Kamisu City, Ibaraki Prefecture, in 2003. The poisoning symptoms associated with the cerebellum and brainstem included nystagmus, tremors, myoclonus, and cerebellar ataxia as well as the symptoms associated with the temporal and occipital lobes such as memory impairment, sleep disorder, and visual disturbance. Some of the affected children exhibited mental retardation. Moreover, reduced blood flow and reduced glucose metabolism in the cerebella, brainstem, and temporal and occipital lobes persisted for several years among the DPAA-exposed persons. Based on the animal studies for DPAA intoxication, the target organs for the DPAA toxicity were determined to be the central nervous system (CNS), liver, and biliary system. In particular, DPAA tends to persist in the brain for a long time, resulting in long-term impacts on the brain. The cerebral blood flow and brain glucose metabolism, which can be measured by positron emission tomography (PET) and single photon emission computed tomography (SPECT), respectively, are useful objective clinical markers to determine the effect of DPAA on CNS. We believe that continuous monitoring of the DPAA-exposed people may promote the effect of carcinogen and accelerate brain aging.

    A new study of gravity waves produced by thunderstorms was performed using continuous recordings at the IS17 (Ivory Coast) infrasound station of the International Monitoring System developed for the verification of the Comprehensive Nuclear Test-Ban Treaty. A typical case study is presented for a large thunderstorm on 10-11 April 2006 lasting near 14 h. Comparison with cloud temperature measured by the Meteosat 6 satellite shows that wave activity is large when the cloud temperature is low inside convection cells located over the station. Statistics based on 10 year data show that the wave activity is intense throughout the year with peak periods in May and October and less intense activity in January, in good agreement with the local keraunic level. The seasonal variations of the wave azimuth highlight clear trends from northward direction from February to August to southward direction from August to December. Lightning flashes, observed from space, show a similar motion confirming that thunderstorms are the main sources of the gravity wave activity. The gravity wave azimuth follows the seasonal motion of the tropical rain belt partly related to the Intertropical Convergence Zone of the winds. The contribution of other possible sources, such as wind over relief, is weak because surface winds are weak in this region and only oceans are present south of the station. We conclude that the large observed wave activity is mainly produced by convection associated to thunderstorms.

    The Conference on Human Vision and Electronic Imaging had its origins as three sessions in the 1988 SPIE/SPSE Symposium on Electronic Imaging Devices and Systems. These sessions brought together visual psychophysicists and imaging scientists and engineers to explore the relevance of human vision to the design of imaging systems. In the early years of the conference, the focus was on display technology and low-level image coding and rendering. The scope of the conference has grown with the evolution of electronic imaging technology, and the conference today includes papers on visualization, machine vision, digital image libraries, and art. Over the years, the conference has become more focused on truly integrating perception and engineering. We have been proud to see how our community has applied knowledge of perceptual systems to create novel engineering designs, and how knowledge of engineering challenges has led to the identification of novel directions for vision research. This paper will examine the progress of this multidisciplinary field as seen through the lens of this conference, and will speculate on where we are headed.

    Disease prevention through vaccination is considered to be the greatest contribution to public health over the past century. Every year more than 100 million children are vaccinated with the standard World Health Organization (WHO)-recommended vaccines including hepatitis B (HepB). HepB is the most serious type of liver infection caused by the hepatitis B virus (HBV), however, it can be prevented by currently available recombinant vaccine, which has an excellent record of safety and effectiveness. To date, recombinant vaccines are produced in many systems of bacteria, yeast, insect, and mammalian and plant cells. Among these platforms, the use of plant cells has received considerable attention in terms of intrinsic safety, scalability, and appropriate modification of target proteins. Research groups worldwide have attempted to develop more efficacious plant-derived vaccines for over 30 diseases, most frequently HepB and influenza. More inspiring, approximately 12 plant-made antigens have already been tested in clinical trials, with successful outcomes. In this study, the latest information from the last 10 years on plant-derived antigens, especially hepatitis B surface antigen, approaches are reviewed and breakthroughs regarding the weak points are also discussed.

    Introduction: Patient surveys are an established tool for quality control in healthcare organizations. This report looks at the design and development of the annual patient surveys carried out among breast cancer patients treated in the Breast Centers of North Rhine-Westphalia and discusses selected findings from 10 consecutive years. Material and Methods: Since 2006 the Institute for Medical Sociology, Health Services Research and Rehabilitation Science (IMVR) of the University of Cologne has carried out an annual survey of breast cancer patients using the Cologne Patient Questionnaire for Breast Cancer. The patients included in the survey have been diagnosed with primary breast cancer and undergo surgery between February and July in one of the Breast Centers in North Rhine-Westphalia accredited by the medical association of Westphalia-Lippe. The questionnaire and the type of feedback given to the Breast Centers were comprehensively revised in 2014. Selected results collected over the survey period were analyzed descriptively. Results: The survey period of 10 years provides information on the actual medical care delivered in the Breast Centers based on the data obtained in this period from around 40 000 patients. Some areas showed positive developments over time. Conclusion: The approach used to survey patients, the Cologne Patient Questionnaire for Breast Cancer 2.0 and the benchmark-focused feedback provide an impetus for organizational learning in Breast Centers. The concept could also be used in other healthcare organizations to stimulate learning and improve healthcare services. PMID:26855439

    A ten year experience at the national french marketing authorization committee has permitted to notice the most commonly methodological errors in the field of clinical research and, particularly, in the dossiers for drug approval: a frequent insufficient sample size resulting in lack of statistical power, an unsatisfactory optimal dosing research, a misuse of the so-called surrogate markers, an erroneous opinion about the meaning of the p value, an abusive claim for equivalence in non significant superiority trials, a misuse of unadjusted multiple comparisons and too much confidence in subgroup analysis results.

  2. Ten-Year Retrospective Longitudinal-Study of Student Perspectives on Value of REU

    For more than two decades, federal agencies have been enthusiastically supporting summer research experiences for undergraduates. These REU programs are tacitly intended to increase retention and provide "an important educational experience" for undergraduates, particularly women, minorities and underrepresented groups. Numerous authors (viz., Laursen, Lopatto, Dolan, among many others) have enthusiastically described positive impacts of summer REU programs from exit interview data. These results include enhanced persistence to pursue STEM careers and confirmed desire to attend graduate school in the field targeted by a particular REU. Perhaps surprisingly, negative student experiences are rarely described in the scholarly literature, but do appear in more informal publications (viz., Gueterma, 2007). One wonders how REU alumni, looking back over their entire collective portfolio of experiences, now perceive the educational value of their REU experience relative to their other educational experiences. To obtain a backwards-looking, reflective description from REU alumni on the value of their REU experiences, we conducted a 10-year, two-stage study was designed to explore the ways in which the REU acted as an educational experience for 51 women from a single geoscience sub-discipline. The first phase was an ex post facto longitudinal analysis of data, including multiple interviews with each participant during their REU, annual open-ended alumni surveys, faculty interviews, and extensive field notes, over a 10-year period. This analysis informed the second phase, a clinical interview. Over 10 hours of interviews with 8 participants were conducted and analyzed. These 8 participants were selected to represent a variety of career stages, and for their potential to reflect on a wide variety of educational experiences. Results from the interviews, done many years after their REU experience, indicate that the interviewees' REU did not provide a substantive educational

    Polycyclic aromatic hydrocarbons (PAHs) are well-known air pollutants of health concern. However, they are not listed as routinely measured pollutants in China, in spite of benzo[a]pyrene (BaP) being included in the National Ambient Air Quality Standard (NAAQS). Thus, very limited continuous measurements are available for PAHs, which would hinder the understanding of long-term pollution characteristics of PAHs in context of rapid development of economy and intensive urbanization in China. To investigate annual variation and its causes of airborne particulate-associated PAHs, a total of 18 PAHs (including 16 USEPA priority species) in PM10 and PM2.5 were measured in Beijing, the capital and one of megacities of China, for a decade (from the year of 2004 to 2013) with meteorological data simultaneously recorded. The long-term measurements of PAHs showed significant annual and seasonal variations for the total concentration of PAHs (ΣPAH18) and individual PAH species. The ΣPAH18 in PM10 was highest in 2010 and lowest in 2006. Likewise, the ΣPAH18 in PM2.5 reached the highest level in 2010 and dropped to the lowest level in 2005. The annual concentration varied insignificantly for 2- and 3-ring PAHs, were relatively high in the year of 2004, 2007 and 2010 for 4-ring PAHs, and increased gradually with year for 5- to 7-ring PAHs, the markers of motor vehicle emission. As for seasonal variation, the concentrations in winter (heating period) was higher than those in summer, while concentrations in spring and autumn ranked in the middle. As for BaP, one of criteria pollutants, its concentration exceeded NAAQS of China in winter. Source apportionment by factor analysis suggested the contributions of coal combustion, vehicle emissions, fugitive dust and straw burning. Especially, the great contributions of coal combustion and vehicle emission were also supported by diagnostic ratios. The backward trajectories showed air mass crossing polluted cities and transporting in low

    The development of ideas on CETI within the international community over the past five years is reviewed, and the outlook for future CETI activities is discussed. The growth of review sessions on CETI held annually by the International Academy of Astronautics (IAA) is considered, with particular attention given to the issue of radio frequency allocation for the search for extraterrestrial intelligence. CETI activities outside the IAA are then examined, including the Viking search for life on Mars, Project Orion for the detection of extrasolar planetary systems, SETI programs undertaken in the U.S. and Soviet Union, and the development of multispectral spectrum analyzers and signal processors. The expected future development of CETI strategies, techniques and instrumentation as well as popular and scientific interest in SETI are discussed, and it is noted that the IAA sessions remain the only regular international forum for the exchange of data on all aspects of CETI.

    Pythiosis is a disease caused by Pythium insidiosum, a fungus-like organism. P. insidiosum is pathogenic in mammals, particularly in horses, dogs, and humans. Human pythiosis can be classified into 4 types: (1) cutaneous/subcutaneous, (2) ocular, (3) vascular, and (4) disseminated pythiosis. Vascular pythiosis is a rare disease but a serious limb- and life-threatening infection. We reviewed 22 cases over a 10-year period in Maharaj Nakorn Chiang Mai/Chiang Mai University Hospital. The survival rate was around 63.6% during our follow-up period. The only effective treatment was complete excision of the infected tissue, which was done mainly by major amputation, such as above-knee amputation. This report raises awareness of this disease, which needs preemptive diagnosis and appropriate treatment. PMID:26286930

    Hypospadias is more common than cleft lip and palate. However, in comparison to the latter, few units have dedicated any team to its correction. Hence, urologists, paediatric surgeons, plastic surgeons, general surgeons and paediatric urologists keep trying various methods of correcting this deformity. That more than 350 procedures have been described for the correction of one anomaly speaks volumes of dissatisfaction with the results. We describe our humble experience with this anomaly over a period of 10 years during which time we were able to treat 1415 cases. However, this paper only describes results of 1206 patients. We use universally only one technique for hypospadias repair and perform this in two stages. This technique has been described by many but lately popularized by Aivar Bracka from UK. Our overall fistula rate has been 3.8% though most of the fistulae occurred in the earlier period. Other complications included repeated UTI (3%) and hair growth in the urethra (0.2%).

    Pedagogical content knowledge (PCK) is a much debated and studied construct. In this article, we adopt an all-embracing view of PCK to examine the development of one elementary science teacher's knowledge over a 10-year period. We portray this teacher's knowledge at three critical points in her career - as a student teacher, beginning teacher, and established teacher - and represent and analyze the growth of her science PCK using the metaphor of a knowledge tree. The tree metaphor shows that while science knowledge begins as the major branch of science PCK, it is soon overshadowed by the general teaching and interactive knowledge branches of science PCK; however, taken together, all three branches contribute over time to the formation of a healthy, established tree of science PCK.

    Whether it's footdragging, or compliance is impossible, the Environmental Protection Agency (EPA) usually fails to meet its deadlines for issuing regulations. The best-known case is probably EPA's 10-year struggle to establish regulatory controls on toxic pollutants under the Clean Water Act. The developmental process is reviewed from the initial statutory framework (enacted in 1948) and the effluent limitations amendments (legislated in 1972), through its litigation history, to an analysis of the federal district court's three substantive opinions delivered during 1982. The author considers the possibility of legislative intervention because deadlines for compliance have been issued but the regulations have not. He concludes that without Toxics Consent Decree litigation, the toxic pollutant control program might have become a reality. EPA's toxic pollutant control regulations as of April 1, 1983, are tabulated. 129 references, 4 tables.

    The Three Gorges Dam (TGD), the world’s largest source of ‘clean’ hydroelectric power (Shen and Xie 2004), has entered its tenth year after the first turbine went into operation in June 2003. The dam, with a generating capacity 20 times that of the United States’ Hoover Dam, has been hailed as a crucial part of a solution to China’s energy crisis. Despite great benefits, however, major concerns have been voiced over the disastrous environmental and social consequences of this massive engineering project (Stone 2011). In this paper, we review the benefits and impacts learned from the controversial megadam over the past decade and discuss perspective quests on policy overhaul for future environmental protection.

    My effort to use synchronously dividing cultures to examine the Escherichia coli cell cycle involved a 10-year struggle with failure after failure punctuated by a few gratifying successes, especially at the end. In this essay, I recount my personal journey in this obsessive experimental pursuit. That narrative is followed by a description of a simplified version of the “baby machine,” a technique that was developed to obtain minimally disturbed, synchronously growing E. coli cells. Subsequent studies with this methodology led to an understanding of the basic properties of the relationship between chromosome replication and cell division. Accordingly, I end this reminiscence with a simple, fool-proof graphical strategy for deducing the pattern of chromosome replication during the division cycle of cells growing at any rate.

    2013-08-01

    In children, pneumococcus became the predominant infectious agent, after the routine use of the Hib conjugate vaccine dramatically decreased Haemophilus Influenzae type b prevalence. The incidence of invasive pneumococcal infections (IPI) and of non-invasive infections due to vaccine serotypes (VS) decreased by 80% in Europe along with a 30-40% decrease in the global incidence of IPI in this age group, after the implementation of Prevenar 7(®) routine immunization in children below 2 years of age. The decrease of IPI due to VS in other age groups was an indirect benefit. The moderate increase of non-vaccinal serotype IPI incidence did not impede the benefit of the overall program. Serotype 19A was the most frequent and carried resistance to antibiotics. Prevenar 13(®), a second-generation vaccine with six new serotypes, replaced Prevenar 7(®) in most countries after 2010, with available evidence of its effectiveness (United Kingdom, US, France).

    Vegetation dynamics and changes in ecological patterns were measured by remote sensing over a 10 year period (1973 to 1983) for 148,406 landscape elements, covering more than 500 sq km in a protected forested wilderness. Quantitative measurements were made possible by methods to detect ecologically meaningful landscape units; these allowed measurement of ecological transition frequencies and calculation of expected recurrence times. Measured ecological transition frequencies reveal boreal forest wilderness as spatially heterogeneous and highly dynamic, with one-sixth of the area in clearings and early successional stages, consistent with recent postulates about the spatial and temporal patterns of natural ecosystems. Differences between managed forest areas and a protected wilderness allow assessment of different management regimes.

    For more than a decade, casinos around the world have offered self-exclusion programs (SEPs) to gamblers seeking help with their gambling behavior. Despite the proliferation of SEPs, little is known about the long-term outcomes for gamblers who utilize these programs. The current study assessed the experiences of a sample (N = 113) of Missouri self-excluders (SEs) for as long as 10 years after their initial enrollment in the Missouri Voluntary Exclusion Program (MVEP). Most SEs had positive experiences with MVEP and reduced their gambling and gambling problems after enrollment. However, 50% of SEs who attempted to trespass at Missouri casinos after enrollment were able to, indicating that the benefit of MVEP was attributable more to the act of enrollment than enforcement. SEs who engaged in complementary treatment or self-help groups had more positive outcomes than those who did not, suggesting that SEPs ought to encourage and provide information about additional support and treatment options to participants.

    Previous studies have shown that values are developed during young adulthood. This study investigated whether and when developmental trajectories of values depend on gender, language region, cognitive competence, expected education duration, and ambition. Longitudinal data of 2620 adolescents in Switzerland were collected at eight waves of measurement over 10 years. Latent growth model analysis revealed that work values mainly increase between ages 16 and 20, whereas family values primarily increase after age 20. This pattern fits the major life and career roles sequence: Becoming established in one's career comes first, and focusing on family building follows later. The initial levels and development of values were essentially affected by gender, but other individual factors such as cognitive competence, expected education duration, and ambition also showed some effect, particularly on family values. These new insights into the development of values improve the understanding of the career decisions and career behavior of adolescents. PMID:25899131

  16. Ten Years of Vegetation Change in Northern California Marshlands Detected using Landsat Satellite Image Analysis

    Potter, Christopher

    2013-01-01

    The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) methodology was applied to detected changes in perennial vegetation cover at marshland sites in Northern California reported to have undergone restoration between 1999 and 2009. Results showed extensive contiguous areas of restored marshland plant cover at 10 of the 14 sites selected. Gains in either woody shrub cover and/or from recovery of herbaceous cover that remains productive and evergreen on a year-round basis could be mapped out from the image results. However, LEDAPS may not be highly sensitive changes in wetlands that have been restored mainly with seasonal herbaceous cover (e.g., vernal pools), due to the ephemeral nature of the plant greenness signal. Based on this evaluation, the LEDAPS methodology would be capable of fulfilling a pressing need for consistent, continual, low-cost monitoring of changes in marshland ecosystems of the Pacific Flyway.

  17. Jamming in granular hopper flow.

    Landry, James W.; Grest, Gary Stephen

    2005-06-01

    Large-scale three dimensional molecular dynamics simulations of hopper flow are presented. The flow rate of the system is controlled by the width of the aperture at the bottom. As the steady-state flow rate is reduced, the force distribution P(f) changes only slightly, while there is a large change in the impulse distribution P(i). In both cases, the distributions show an increase in small forces or impulses as the systems approach jamming, the opposite of that seen in previous Lennard-Jones simulations. This occurs dynamically as well for a hopper that transitions from a flowing to a jammed state over time. The final jammed P(f) is quite distinct from a poured packing P(f) in the same geometry. The change in P(i) is a much stronger indicator of the approach to jamming. The formation of a peak or plateau in P(f) at the average force is not a general feature of the approach to jamming.

    This paper presents a case study of an approach to sustainable software architecture that has been successfully applied over a period of 10 years to astronomy software services at the NASA Infrared Processing and Analysis Center (IPAC), Caltech (http://www.ipac.caltech.edu). The approach was developed in response to the need to build and maintain the NASA Infrared Science Archive (http://irsa.ipac.caltech.edu), NASA's archive node for infrared astronomy datasets. When the archive opened for business in 1999 serving only two datasets, it was understood that the holdings would grow rapidly in size and diversity, and consequently in the number of queries and volume of data download. It was also understood that platforms and browsers would be modernized, that user interfaces would need to be replaced and that new functionality outside of the scope of the original specifications would be needed. The changes in scientific functionality over time are largely driven by the archive user community, whose interests are represented by a formal user panel. The approach has been extended to support four more major astronomy archives, which today host data from more than 40 missions and projects, to support a complete modernization of a powerful and unique legacy astronomy application for co-adding survey data, and to support deployment of Montage, a powerful image mosaic engine for astronomy. The approach involves using a component-based architecture, designed from the outset to support sustainability, extensibility and portability. Although successful, the approach demands careful assessment of new and emerging technologies before adopting them, and attention to a disciplined approach to software engineering and maintenance. The paper concludes with a list of best practices for software sustainability that are based on 10 years of experience at IPAC.

    Study Design Retrospective study. Purpose To evaluate the factors affecting immediate postoperative mortality in elderly patients with tuberculous spondylodiscitis. Overview of Literature Treatment of spinal tuberculosis in the elderly involves consideration of age and co-morbidities, and often leads to an extended conservative management. Surgical intervention in these patients becomes a complex decision. There are no studies on risk factors of mortality in surgically treated elderly with tuberculous spondylodiscitis. Methods Two hundred and seventy-six patients with spondylodiscitis were operated between 2005 and 2015. 20 consecutive patients over 70 years of age with and proven tuberculosis who met the inclusion/exclusion criteria were included. Demographic, clinical and radiological profile data with operative details of instrumentation, blood loss, surgical duration, and mortality were noted. There were 20 patients (6 males, 14 females) with a mean age of 73.5 years. The patients were divided into those with mortality (M) and those who survived (non-mortality, NM). Various variables were statistically tested for immediate postoperative medical complications and mortality. Results There were four mortalities (20%). Age, sex, number of medical co-morbidities, American Society of Anaesthesiologists grade, Frankel grade C or worse, number of vertebrae involved, number of levels fused, blood loss and operative time did not have statistically significant impact on immediate postoperative mortality. Only preoperative immobility duration was statistically higher in the M group (p=0.016) than in the NM group. Conclusions Preoperative immobility is associated with immediate postoperative mortality in elderly patients with spinal tuberculosis undergoing surgery. The findings identify preoperative immobility as a risk factor for mortality, which could contribute to a more detailed prognostic discussion between surgeon and patient before surgery.

  20. Taking stock of herbicide-resistant crops ten years after introduction.

    Since transgenic, bromoxynil-resistant cotton and glufosinate-resistant canola were introduced in 1995, planting of transgenic herbicide-resistant crops has grown substantially, revolutionizing weed management where they have been available. Before 1995, several commercial herbicide-resistant crops were produced by biotechnology through selection for resistance in tissue culture. However, non-transgenic herbicide-resistant crops have had less commercial impact. Since the introduction of glyphosate-resistant soybean in 1996, and the subsequent introduction of other glyphosate-resistant crops, where available, they have taken a commanding share of the herbicide-resistant crop market, especially in soybean, cotton and canola. The high level of adoption of glyphosate-resistant crops by North American farmers has helped to significantly reduce the value of the remaining herbicide market. This has resulted in reduced investment in herbicide discovery, which may be problematic for addressing future weed-management problems. Introduction of herbicide-resistant crops that can be used with selective herbicides has apparently been hindered by the great success of glyphosate-resistant crops. Evolution of glyphosate-resistant weeds and movement of naturally resistant weed species into glyphosate-resistant crop fields will require increases in the use of other herbicides, but the speed with which these processes compromise the use of glyphosate alone is uncertain. The future of herbicide-resistant crops will be influenced by many factors, including alternative technologies, public opinion and weed resistance. Considering the relatively few recent approvals for field testing new herbicide-resistant crops and recent decisions not to grow glyphosate-resistant sugarbeet and wheat, the introduction and adoption of herbicide-resistant crops during the next 10 years is not likely to be as dramatic as in the past 10 years.

  1. Ten years of satellite observations reveal highly variable sulphur dioxide emissions at Anatahan Volcano, Mariana Islands

    Satellite remote sensing enables continuous multiyear observations of volcanic activity in remote settings. Anatahan (Mariana Islands) is a remote volcano in the western North Pacific. Available ground-based measurements of sulphur dioxide (SO2) gas emissions at Anatahan place it among thelargest volcanic SO2 sources worldwide. These ground-based measurements, however, are restricted to eruptive intervals. Anatahan's activity since 2003 has been dominated temporally by prolonged periods of quiescence. Using 10 years of satellite observations from OMI, AIRS, SCIAMACHY, and GOME-2, we report highly variable SO2 emissions within and between eruptive and quiescent intervals at Anatahan. We find close correspondence between levels of activity reported at the volcano and levels of SO2 emissions detected from space. Eruptive SO2 emission rates have a mean value of ˜6400 t d-1, but frequently are in excess of 20,000 t d-1. Conversely, SO2 emissions during quiescent intervals are below the detection limit of space-based sensors and therefore are not likely to exceed ˜300 t d-1. We show that while Anatahan occupies a quiescent state for 85% of the past 10 years, only ˜15% of total SO2 emissions over this interval occur during quiescence, with the remaining ˜85% released in short duration but intense syn-eruptive degassing. We propose that the integration of multiyear satellite data sets and activity histories are a powerful complement to targeted ground-based campaign measurements in better describing the long-term degassing behavior of remote volcanoes.

    The treatment of chronic pain, therapeutic opioid use and abuse, and the nonmedical use of prescription drugs have been topics of intense focus and debate. After the liberalization of laws governing opioid prescribing for the treatment of chronic non-cancer pain by state medical boards in the late 1990s, and with the introduction of new pain management standards implemented by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) in 2000, opioids, in general, and the most potent forms of opioids including Schedule II drugs, in particular, have dramatically increased. Despite the escalating use and abuse of therapeutic opioids, nearly 15 to 20 years later the scientific evidence for the effectiveness of opioids for chronic non-cancer pain remains unclear. Concerns continue regarding efficacy; problematic physiologic effects such as hyperalgesia, hypogonadism and sexual dysfunction; and adverse side effects - especially the potential for misuse and abuse - and the increase in opioid-related deaths. Americans, constituting only 4.6% of the world's population, have been consuming 80% of the global opioid supply, and 99% of the global hydrocodone supply, as well as two-thirds of the world's illegal drugs. Retail sales of commonly used opioid medications (including methadone, oxycodone, fentanyl base, hydromorphone, hydrocodone, morphine, meperidine, and codeine) have increased from a total of 50.7 million grams in 1997 to 126.5 million grams in 2007. This is an overall increase of 149% with increases ranging from 222% for morphine, 280% for hydrocodone, 319% for hydromorphone, 525% for fentanyl base, 866% for oxycodone, to 1,293% for methadone. Average sales of opioids per person have increased from 74 milligrams in 1997 to 369 milligrams in 2007, a 402% increase.

    The purpose of this study was to evaluate the clinical results, complications, and secondary interventions during long-term follow-up after endovascular aneurysm repair (EVAR) and to investigate the impact of endoleak sizes on aneurysm shrinkage. From 1997 to March 2007, 127 patients (12 female, 115 male; age, 73.0 {+-} 7.2 years) with abdominal aortic aneurysms were treated with Talent stent-grafts. Follow-up included clinical visits, contrast-enhanced MDCT, and radiographs at 3, 6, and 12 months and then annually. Results were analyzed with respect to clinical outcome, secondary interventions, endoleak rate and management, and change in aneurysm size. There was no need for primary conversion surgery. Thirty-day mortality was 1.6% (two myocardial infarctions). Procedure-related morbidity was 2.4% (paraplegia, partial infarction of one kidney, and inguinal bleeding requiring surgery). Mean follow-up was 47.7 {+-} 34.2 months (range, 0-123 months). Thirty-nine patients died during follow-up; three of the deaths were related to aneurysm (aneurysm rupture due to endoleak, n = 1; secondary surgical reintervention n = 2). During follow-up, a total of 29 secondary procedures were performed in 19 patients, including 14 percutaneous procedures (10 patients) and 15 surgical procedures (12 patients), including 4 cases with late conversion to open aortic repair (stent-graft infection, n = 1; migration, endoleak, or endotension, n = 3). Overall mean survival was 84.5 {+-} 4.7 months. Mean survival and freedom from any event was 66.7 {+-} 4.5 months. MRI depicted significantly more endoleaks compared to MDCT (23.5% vs. 14.3%; P < 0.01). Patients in whom all aneurysm side branches were occluded prior to stent-grafting showed a significantly reduced incidence of large endoleaks. Endoleaks >10% of the aneurysm area were associated with reduced aneurysm shrinkage compared to no endoleaks or <10% endoleaks ({Delta} at 3 years, -1.8% vs. -12.0%; P < 0.05). In conclusion, endovascular

    Breast cancer is the leading type of malignancy and the leading cause of cancer-related deaths in women worldwide. The screening programs and advances in the treatment of patients with breast cancer have led to an increase in overall survival. Cancer registry systems play an important role in providing basic data for research and the monitoring of the cancer status. In this study, the results of the 10-year national cancer registry (NCR) of Iran in breast cancer are reviewed. NCR database records were searched for primary breast cancer records according to ICD-O-3 coding and the cases were reviewed. A total of 52,068 cases were found with the coding of primary breast cancer. Females constituted 97.1% of the cases. Breast cancer was the leading type of cancer in Iranian females, accounting for 24.6% of all cancers. The mean age of the women with breast cancer was 49.6 years (95%CI 49.5-49.6). Most of the cases (95.7%) were registered as having invasive pathologies (behavior code 3). The most common morphology of primary breast cancer was invasive ductal carcinoma (ICD-O 8500/3) followed by invasive lobular carcinoma (ICD-O 8520/3) with relative frequencies of 77.8% and 5.2%, respectively. The average annual crude incidence of primary breast cancer in females was 22.6 (95%CI 22.1-23.1) per 100,000 females, with an age-standardized rate (ASR) of 27.4 (95%CI 22.5-35.9). There were no data on survival, staging or immunohistochemical marker(s) of the breast-cancer-registered cases. The incidence of breast cancer in Iran is lower than in low-middle-income neighboring countries. The NCR data registry of breast cancer is not accurate in monitoring the effect of screening programs or determining the current status of breast cancer in Iran. Screening programs of breast cancer in Iran have failed to enhance the detection of the patients with in situ lesion detection. A quality breast cancer registry and a screening program for breast cancer are both needed.

    Background The simple renal cyst is the most common benign kidney disease. It may cause pain and hypertension, especially if significantly enlarged. As in polycystic kidney disease, blood cell count disturbances are frequently observed in simple renal cysts. The aim of our study was to assess such disturbances, changes in blood pressure, and complication rate in our patients undergoing surgery due to simple renal cyst in the last 10 years. Material/Methods 210 patients with simple renal cysts were underwent surgery between 2002 and 2012. Two different kinds of operation were conducted: aspiration of cyst fluid with injection of sclerosing agent, and laparoscopic/retroperitoneoscopic decortications of the cyst wall. A control group comprised 134 patients with benign prostate hyperplasia. The following data were obtained: cyst burden, hematocrit, hemoglobin, red blood cells, thrombocytes, occurrence of pain, and blood pressure before and after the operation. Complications were collected and presented in Clavien score. Results Hematocrit, hemoglobin, and red blood cells were significantly increased in the experimental group. A positive correlation was observed between cyst burden and the parameters mentioned above. Of 91 patients with hypertension, 56 (61.7%) had blood pressure reduction after the operation. Treatment relieved the loin pain in 132 (88%) patients. Complications occurred in 15 (7.4%) patients. Conclusions Patients with simple renal cysts have high values of red blood cells, hematocrit, and hemoglobin. Treatment decreases blood pressure in patients with hypertension. Complications after treatment are rare and mild. PMID:23811552

    The ability of reserves to replenish fish stocks is relatively well documented, but the evidence of their ability to induce positive effects on benthic communities remains inconclusive. Here, we test whether 10 years of reserve designation have translated into positive effects on coral communities in Glover's Reef, Belize. Surveys of 87 patch reefs inside and outside the reserve revealed no clear indication of reserve implementation benefitting coral cover, coral colony size, or abundance of juvenile corals. Furthermore, massive broadcasting coral species exhibited greater losses over time than their smaller-sized counterparts across all sites, suggesting that local management actions have not alleviated the regional trend of high mortality for these species. We detected no difference in herbivorous fish abundances or macroalgal cover between reserve and fished sites, providing a potential explanation for the lack of cascading positive effects on the coral community. We conclude that patterns of regional coral decline are evident at Glover's Reef, including a shift in dominance from broadcasting species to brooding species and declines in mean colony size. Our findings suggest that regional stressors are overwhelming local management efforts and that additional strategies are required to improve local coral condition.

    Introduction Preanalytical control and monitoring continue to be an important issue for clinical laboratory professionals. The aim of the study was to evaluate a monitoring system of preanalytical errors regarding not suitable samples for analysis, based on different indicators; to compare such indicators in different phlebotomy centres; and finally to evaluate a single synthetic preanalytical indicator that may be included in the balanced scorecard management system (BSC). Materials and methods We collected individual and global preanalytical errors in haematology, coagulation, chemistry, and urine samples analysis. We also analyzed a synthetic indicator that represents the sum of all types of preanalytical errors, expressed in a sigma level. We studied the evolution of those indicators over time and compared indicator results by way of the comparison of proportions and Chi-square. Results There was a decrease in the number of errors along the years (P < 0.001). This pattern was confirmed in primary care patients, inpatients and outpatients. In blood samples, fewer errors occurred in outpatients, followed by inpatients. Conclusion We present a practical and effective methodology to monitor unsuitable sample preanalytical errors. The synthetic indicator results summarize overall preanalytical sample errors, and can be used as part of BSC management system. PMID:25672466

    We reviewed all 50 body packer deaths in New York City from 1990 to 2001. The majority (37/50) of deaths were caused by acute intoxications due to open or leaking drug packets in the gastrointestinal tract. The number of packets recovered ranged from 1 to 111 (average 46). The weight of the combined packets ranged from 9.4 to 1,200 g (average of 377). The age ranged from 19 to 57 years (mean 37.1). The decedents were: 82% male, 66% Hispanic, 24% Black, and 10% White. The manners of death were 47 accidents, 1 homicide, 1 natural, and 1 undetermined. The causes of death included 42 acute intoxications, 5 intestinal obstructions/bowel perforations, 1 gunshot wound, 1 intracerebral hemorrhage due to hypertensive disease, and 1 undetermined. Of the 50 decedents, 42 were transporting opiates, 4 cocaine, and 4 both opiates and cocaine. There were 9 deaths from 1990-1995 and 41 from 1996-2001. Of the 41 deaths between 1996 and 2001, only 6 involved cocaine. In New York City there has been an increase in body packer deaths from the early 1990s to the late 1990s. Along with this increase is a marked predominance of opiate body packer deaths with few cocaine deaths.

    The aim of this study is to evaluate the pregnancy outcomes and prognoses for fetuses with ventriculomegaly. Two hundred and forty-one cases of fetuses with ventriculomegaly were included in this study. The subjects were divided into three groups according to their lateral ventricular width: "Mild Ventriculomegaly" (10 ‒ < 12 mm), "Moderate Ventriculomegaly" (12 ‒ < 15 mm) and "Severe Ventriculomegaly" (≥ 15 mm). Pediatric examination records and telephone interviews were conducted to track the outcomes of children until the age of 9 years. Eight-two cases were Isolated Ventriculomegaly (34.0%), while Non-Isolated Ventriculomegaly was found in 159 cases (66.0%). The pregnancy was terminated in 91 cases, and a higher abortion ratio was found in the NIVM (Non-Isolated Ventriculomegaly) group compared with the IVM (Isolated Ventriculomegaly) group. The fetuses were delivered in 150 cases, and four infants suffered deaths with NIVM. Of the surviving fetuses, 7 with IVM and 9 with NIVM showed significant abnormalities. The Mild and Moderate VM groups had more favorable prognoses compared with the Severe VM group. Regarding the outcomes and progression of lateral ventricular width, 1 out of 42 cases in the regressed group and 19 out of 108 cases in the stable group showed significant abnormalities. This study suggests that the degree and the progression of ventricular dilatation are main factors that affect pregnancy outcomes and prognoses.

    2015-02-01

    Molecular ecology has moved beyond the use of a relatively small number of markers, often noncoding, and it is now possible to use whole-genome measures of gene expression with microarrays and RNAseq (i.e. transcriptomics) to capture molecular response to environmental challenges. While transcriptome studies are shedding light on the mechanistic basis of traits as complex as personality or physiological response to catastrophic events, these approaches are still challenging because of the required technical expertise, difficulties with analysis and cost. Still, we found that in the last 10 years, 575 studies used microarrays or RNAseq in ecology. These studies broadly address three questions that reflect the progression of the field: (i) How much variation in gene expression is there and how is it structured? (ii) How do environmental stimuli affect gene expression? (iii) How does gene expression affect phenotype? We discuss technical aspects of RNAseq and microarray technology, and a framework that leverages the advantages of both. Further, we highlight future directions of research, particularly related to moving beyond correlation and the development of additional annotation resources. Measuring gene expression across an array of taxa in ecological settings promises to enrich our understanding of ecology and genome function.

    2012-03-10

    Criticism of forensic science, particularly that of bitemark analysis, has become increasingly common in the last decade. Much of the criticism directed at forensic odontology cites cases where miscarriages of justice have occurred when erroneous, over-confident or even false bitemark evidence has been tendered by odontologists. Despite Australia's own experience with such cases in the past, it is postulated that this does not represent the true nature of bitemark analysis as practiced by odontologists today-at least in this country. A review of 119 cases from the last 10 years confirms that 'identification' of a suspect is rarely, if ever, offered, and that conclusions reached by odontologists with respect to bitemark analysis are generally conservative. However, the results of this study also indicate that in a small but significant proportion of cases, there is still some tendency to reach conclusions that could be considered over-confident when considering the overall quality of the physical evidence offered. It is suggested that odontologists should avoid making conclusive remarks regarding the origin of the mark, or the identification of a perpetrator, when such comments are realistically precluded, given the low evidentiary value of the mark itself.

    A possible evolution of Columbus, bearing in mind the changes in the situation that have occurred over the last decade, is described. The ultimate goals that the program can realistically achieve in the international exploitation of space are focused upon. The large infrastructures which were conceived many years ago as an area of international cooperation in the conquest of space, and which started at the beginning of the 1980's with the Space Station and Columbus programs, have undergone a difficult development over the last decade and have had to suffer the resulting delays. The economic difficulties which faced the spacefaring nations, including Europe, in this period have led to much replanning and reprogramming which, together with the upheavals in the East, have demanded a rethinking of the strategies to achieve the original goals as fully as possible. The role of the Columbus Attached laboratory, or Attached Pressurized Module, as a European contribution to Space Station Freedom, in its new configuration dictated by the problems the U.S. has had to confront, is highlighted as an area for new strategies. Its basic features and characteristics are described. With regard to the Free Flying Laboratory, the prospects for this element will be the subject of new thinking, especially in the light of new international cooperation.

    Launched in March 2005, the Integrated Microbial Genomes (IMG) system is a comprehensive data management system that supports multidimensional comparative analysis of genomic data. At the core of the IMG system is a data warehouse that contains genome and metagenome datasets sequenced at the Joint Genome Institute or provided by scientific users, as well as public genome datasets available at the National Center for Biotechnology Information Genbank sequence data archive. Genomes and metagenome datasets are processed using IMG's microbial genome and metagenome sequence data processing pipelines and are integrated into the data warehouse using IMG's data integration toolkits. Microbial genome and metagenome application specific data marts and user interfaces provide access to different subsets of IMG's data and analysis toolkits. This review article revisits IMG's original aims, highlights key milestones reached by the system during the past 10 years, and discusses the main challenges faced by a rapidly expanding system, in particular the complexity of maintaining such a system in an academic setting with limited budgets and computing and data management infrastructure.

    Puxbaum, H.; Simeonov, V.; Kalina, M. F.

    Since 1984, wet precipitation samples have been collected from five sampling sites in the eastern Alpine region of Austria. The chemical analysis performed included pH, NH 4+, Na +, K +, Ca 2+, Mg 2+, Cl -, NO 3- SO 42- and precipitation amount. These data were used to determine the 10 years (1984-1993) trends in precipitation chemistry and deposition for all major ions. The statistical data treatment by the use of least-squares linear regression revealed a significant decrease of sulfate and hydrogen ion concentrations and depositions at all sites in consideration (above 65% for hydrogen ion and over 33% for sulfate concentration and 40% for hydrogen and 36% for sulfate deposition). An effort is made to explain the acidity decrease not only by the parallel decrease of sulfate concentration but by the participation of the other constituents of the wet precipitation events. It has been found that when the hydrogen ion concentration decrease is stronger than that of sulfate ion concentrations a compensation mainly by ammonium ion concentration increase is achieved. On the contrary, when the hydrogen ion concentration decrease is weaker than sulfate concentration decrease, a calcium ion concentration decrease is present for the sites in consideration. The results obtained indicate that the precipitation chemistry in Central Austria follows the global trends of controlled reduction of atmospheric acidity.

    This review summarizes a prospective, longitudinal 10-year study in Rochester, NY, with virtually every clinically diagnosed acute otitis media (AOM) confirmed by bacterial culture of middle ear fluid. Children experiencing 3 episodes within 6 months or 4 episodes in 12 months were considered stringently defined otitis prone (sOP). We found stringent diagnosis compared with clinical diagnosis reduced the frequency of children meeting the OP definition from 27% to 6% resulting in 14.8% and 2.4% receiving tympanostomy tubes, respectively. Significantly more often respiratory syncytial virus infection led to AOM in sOP than non-otitis-prone children that correlated with diminished total respiratory syncytial virus-specific serum IgG. sOP children produced low levels of antibody to Streptococcus pneumoniae and Haemophilus influenzae candidate vaccine protein antigens and to routine pediatric vaccines. sOP children generated significantly fewer memory B cells, functional and memory T cells to otopathogens following nasopharyngeal colonization and AOM than non-otitis-prone children and they had defects in antigen-presenting cells.

    We started the near-infrared variable star survey in the Large and Small Magellanic Clouds in December 2000. Since then, we keep monitoring an area of 3 square degrees along the bar in the LMC, and also an area of 1 square degree in the central part of the SMC until the end of 2010. In the 10 years, we observed these areas about 80-90 and 100-110 times for LMC and SMC, respectively. Our survey is the world's first and the only one that provides near-infrared time-series data with such a long baseline and of such a large scale. We will show some preliminary results from the survey in the poster.

    Climatological features of mesoscale rain activities over the Mediterranean region between 5 W-40 E and 28 N-48 N are examined using the Tropical Rainfall Measuring Mission (TRMM) 3B42 and 2A25 rain products. The 3B42 rainrates at 3-hourly, 0.25 deg x 0.25 deg spatial resolution for the last 10 years (January 1998 to July 2007) are used to form and analyze the 5-day mean and monthly mean climatology of rainfall. Results show considerable regional and seasonal differences of rainfall over the Mediterranean Region. The maximum rainfall (3-5 mm/day) occurs over the mountain regions of Europe, while the minimum rainfall is observed over North Africa (approximately 0.5 mm/day). The main rainy season over the Mediterranean Sea extends from October to March, with maximum rainfall occurring during November-December. Over the Mediterranean Sea, an average rainrate of approximately 1-2 mm/day is observed, but during the rainy season there is 20% larger rainfall over the western Mediterranean Sea than that over the eastern Mediterranean Sea. During the rainy season, mesoscale rain systems generally propagate from west to east and from north to south over the Mediterranean region, likely to be associated with Mediterranean cyclonic disturbances resulting from interactions among large-scale circulation, orography, and land-sea temperature contrast.

    Launched in March 2005, the Integrated Microbial Genomes (IMG) system is a comprehensive data management system that supports multidimensional comparative analysis of genomic data. At the core of the IMG system is a data warehouse that contains genome and metagenome datasets sequenced at the Joint Genome Institute or provided by scientific users, as well as public genome datasets available at the National Center for Biotechnology Information Genbank sequence data archive. Genomes and metagenome datasets are processed using IMG's microbial genome and metagenome sequence data processing pipelines and are integrated into the data warehouse using IMG's data integration toolkits. Microbial genome and metagenome application specific data marts and user interfaces provide access to different subsets of IMG's data and analysis toolkits. This review article revisits IMG's original aims, highlights key milestones reached by the system during the past 10 years, and discusses the main challenges faced by a rapidly expanding system, in particular the complexity of maintaining such a system in an academic setting with limited budgets and computing and data management infrastructure.

    Background Umbilical cord blood (UCB) has successfully used for transplantation to treat hematologic malignancies and genetic diseases. Herein, we describe the experience generated in a single public UCB bank at Zhejiang Province in China. Methods Good manufacturing practice and standard operating procedures were used to address donor selection as well as UCB collection, processing, and cryopreservation. Total nucleated cells (TNCs), cellular viability, CD34+ cells, and colony-forming units were determined, and infectious diseases screening test, sterility test, and HLA typing for UCB units were done. Results Only 18.51% of all collected UCB units met storage criteria, and 7,056 UCB units were cryopreserved in 10 years. The volume of UCB units was 95.0 ± 22.0 ml. The number of TNCs before and after processing was 13.32 ± 3.63 × 108 and 10.63 ± 2.80 × 108, respectively, and the recovery rate was 80.71 ± 11.26%. 0.4344 ± 0.1874% of the TNCs were CD34+ cells. The CFU-GM was 32.1 ± 28.0 colonies per 1 × 105 nucleated cells. Based mainly on HLA and nucleated cell content, 26 UCB units were released for transplantation. Conclusions A public UCB bank was successfully established in China; collection and processing of UCB units should be optimized in order to gain maximum volume and cell count. PMID:22896763

    Landsat satellite imagery was analyzed to generate a detailed record of 10 years of vegetation disturbance and regrowth for Pacific coastal areas of Marin and San Francisco Counties. The Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS) methodology, a transformation of Tasseled-Cap data space, was applied to detected changes in perennial coastal shrubland, woodland, and forest cover from 1999 to 2009. Results showed several principal points of interest, within which extensive contiguous areas of similar LEDAPS vegetation change (either disturbed or restored) were detected. Regrowth areas were delineated as burned forest areas in the Point Reyes National Seashore (PRNS) from the 1995 Vision Fire. LEDAPS-detected disturbance patterns on Inverness Ridge, PRNS in areas observed with dieback of tanoak and bay laurel trees was consistent with defoliation by sudden oak death (Phytophthora ramorum). LEDAPS regrowth pixels were detected over much of the predominantly grassland/herbaceous cover of the Olema Valley ranchland near PRNS. Extensive restoration of perennial vegetation cover on Crissy Field, Baker Beach and Lobos Creek dunes in San Francisco was identified. Based on these examples, the LEDAPS methodology will be capable of fulfilling much of the need for continual, low-cost monitoring of emerging changes to coastal ecosystems.

    We propose a theoretical framework for predicting the protocol dependence of the jamming transition for frictionless spherical particles that interact via repulsive contact forces. We study isostatic jammed disk packings obtained via two protocols: isotropic compression and simple shear. We show that for frictionless systems, all jammed packings can be obtained via either protocol. However, the probability to obtain a particular jammed packing depends on the packing-generation protocol. We predict the average shear strain required to jam initially unjammed isotropically compressed packings from the density of jammed packings, shape of their basins of attraction, and path traversed in configuration space. We compare our predictions to simulations of shear strain-induced jamming and find quantitative agreement. We also show that the packing fraction range, over which shear strain-induced jamming occurs, tends to zero in the large system limit for frictionless packings with overdamped dynamics.

    A nuclear society, which is a nongovernmental organization of nuclear professionals, appeared in the Soviet Union at the end of the 1980s--when social conditions for such a society had matured. Deep changes in the entire country's social consciousness had promoted the specialists understanding of the need to unite in order to overcome the nuclear community's dissociation, the monopoly of the nuclear ministry, and the secrecy syndrome of all nuclear issues. The new public association announced the guiding principles of its activities to be openness and glasnost and completeness and truthfulness of information supplied to decision makers and to the society as a whole. Important to the information system of the NSR are topical meetings and seminars on quite varied but always actual problems of nuclear energy use, often with foreign participation. The variety of these NSR meeting subjects is illustrated by the titles of several meetings of the last 2 yr: Safety Culture in Nuclear Power, Youth and the Plutonium Challenge, Nuclear Fuel for Mankind, Nuclear Power in Space, Radiation Legacy of the Former-USSR, the Murmansk International Forum Nuclear Fleet and Ecology, and many others. A special place among NSR seminars belongs to the annual meeting, Nuclear Energy and Public Opinion, the Russian analog of the European PIME conference. Starting from distribution of ENS periodicals--the Nuclear Europe Worldscan magazine and Nucleus information sheet--among its members, the NSR soon began publishing its own Informational Bulletin (since 1989). Note that in the first years of the Nuclear Society's existence, it has been possible to publish periodicals, conference proceedings, and even books in English. Unfortunately, financial difficulties of the last years have frozen this most useful activity, which the NSR, however, hopes to resume. In the last period, the materials of the international information agency NucNet, which provides both regular information for the analysis of

  5. Ten Billion Years of Growth: Massive Galaxy Evolution from Structures and Dynamics

    NASA Astrophysics Data System (ADS)

    Bezanson, Rachel

    Once thought to be relies of a much earlier epoch, the most massive local galaxies are red and dead ellipticals, with little ongoing star formation or organized rotation. In the last decade, observations of their assumed progenitors have demonstrated that billions of years ago, massive galaxies were more compact and morphologically different, possibly with more disklike structures. The details of this observed evolution can place constraints on the physical processes that have driven massive galaxy evolution through cosmic time. The work presented in this thesis provides observational constraints on the dynamical and structural evolution of massive galaxies since z ~ 1.5 - 2 using a variety of photometric and spectroscopic surveys, including OBEY, SDSS, NMBS, and UDS. First, we find that although overall densities of these galaxies have decreased with time, the central densities of massive galaxies at high and low redshifts, are quite similar. This suggests that massive galaxies grow "inside-out": compact cores form early and then gradually build a more diffuse envelope of stars in their outskirts. Balancing the need for efficient size growth and consistent number densities of progenitor and descendent galaxies, we conclude that minor-merging is the best physical explanation for the observed size evolution. The remainder of this dissertation focuses on the inferred and measured dynamical evolution of massive galaxies since z ~ 2. Using velocity dispersions inferred by galaxy stellar masses and morphologies, we find that the number density of galaxies at a given velocity dispersion, or velocity dispersion function , is quite stable with redshift since z ~ 1.5, with a weak evolution at the low dispersion end due to a growing population of quenched galaxies. The constancy provides evidence in favor of inside-out growth of galaxies and is consistent with theoretical predictions that the central potentials of massive galaxies are set early. We suggest a toy model that

    It has been more than 10 years since the first bacterial genome sequence was published. Hundreds of bacterial genome sequences are now available for comparative genomics, and searching a given protein against more than a thousand genomes will soon be possible. The subject of this review will address a relatively straightforward question: "What have we learned from this vast amount of new genomic data?" Perhaps one of the most important lessons has been that genetic diversity, at the level of large-scale variation amongst even genomes of the same species, is far greater than was thought. The classical textbook view of evolution relying on the relatively slow accumulation of mutational events at the level of individual bases scattered throughout the genome has changed. One of the most obvious conclusions from examining the sequences from several hundred bacterial genomes is the enormous amount of diversity--even in different genomes from the same bacterial species. This diversity is generated by a variety of mechanisms, including mobile genetic elements and bacteriophages. An examination of the 20 Escherichia coli genomes sequenced so far dramatically illustrates this, with the genome size ranging from 4.6 to 5.5 Mbp; much of the variation appears to be of phage origin. This review also addresses mobile genetic elements, including pathogenicity islands and the structure of transposable elements. There are at least 20 different methods available to compare bacterial genomes. Metagenomics offers the chance to study genomic sequences found in ecosystems, including genomes of species that are difficult to culture. It has become clear that a genome sequence represents more than just a collection of gene sequences for an organism and that information concerning the environment and growth conditions for the organism are important for interpretation of the genomic data. The newly proposed Minimal Information about a Genome Sequence standard has been developed to obtain this

    Object of this study is the versatility of a remote-sensing measurement system through experimental survey of the levels of primary and secondary pollutants in urban areas. For the first time a long-range measurement of different pollutant for a long period are reported in the urban area of Rome. Over 10 years of data collection, levels of NO2, O3, SO2, benzene and toluene are measured and discussed by means of a differential optical absorption spectroscopy (DOAS) system installed at ground level. The period is interesting because it represents one of the most important life-changes in Europe and in Italy: in fact, during the 1990s some significant decrees introduced the catalytic pots and limited the amount of benzene and sulfur dioxide in the fuel. The paper will describe how the main primary and secondary pollutants are changed during all the period: particularly, benzene and SO2 are not over a big social problem for the human health whereas the secondary pollutants, ozone and nitrogen dioxide, have the same trends during the period, meaning a no contribution to their evolution from the atmospheric processes. The DOAS technique is resulted very useful and versatile: comparisons with other traditional analyzers (i.e., GC-PID for benzene and toluene investigations) demonstrate how it allows to have information over all the territory saving the qualitative trends and giving a similar quantitative result. In this respect the authors show that the difference is due to the different sampling ways (the traditional analyzers are punctual whereas the DOAS is a remote-sensing technique covering a wide area) and does not influence the atmospheric process interpretation. Finally, it should be considered that the pollutant trends have been interpreted using the concentration measurements of natural radioactivity as tracer of the dynamic properties of the atmospheric boundary layer.

    2016-01-01

    Background: Cleft lip and palate surgery abroad is devoid of global consensus regarding standards of therapy, follow-up, and outcome. Cleft surgery in Nepal during a 10-year sustained program provided the opportunity to inform on the need for such standards. Methods: Medical records were evaluated from the cleft clinic at Sushma Koirala Memorial Hospital, Sankhu, Kathmandu, Nepal, from 1997 to 2007. Four groups were identified for analysis: total cohort, total surgical cohort (TSC), primary program patients (PPP; patients had not been operated on before), and nonprimary program patients (non-PPP; patients operated on elsewhere before). Patient demographics, diagnostic, primary and secondary surgery (corrective surgery), and follow-up were evaluated. Results: One thousand forty-five patients were eligible for surgery. Three hundred twenty-three of 1,045 patients (30.9%) did not seek treatment, although scheduled for surgery. One thousand two hundred one procedures were performed in 722 patients [TSC; 845 PPP (70.4%); 356 non-PPP (29.64%)]. Corrective procedures were performed in 257 of 1,201 [3.5% (30 of 845 procedures in 509 patients) PPP vs 63.7% (227 of 356 procedures in 213 patients) non-PPP]. One hundred six lips were completely reoperated on (1 PPP vs 105 non-PPP), and 42 palates underwent a total revision (5 PPP vs 37 non-PPP). The surgical outcome of the TSC group in terms of complication rate was similar to the one in developed countries. Conclusions: The high rate of corrective surgery reveals the need for global regulatory mechanisms and the need for nongovernmental organizations to introduce strategies for delivering sustained cleft care until achieving full rehabilitation. The World Health Organization should establish standards for cleft care delivered in less developed countries. PMID:27579235

    Background. Coelomycetes are rarely but increasingly reported in association with human infections involving mostly skin and subcutaneous tissues, both in immunocompetent and immunocompromised patients. Coelomycetes constitute a heterogeneous group of filamentous fungi with distinct morphological characteristics in culture, namely an ability to produce asexual spores within fruit bodies. Methods. We included all cases of proven primary cutaneous and/or subcutaneous infections due to coelomycetes received for identification at the French National Reference Center for Invasive Mycoses and Antifungals between 2005 and 2014. Eumycetoma, chromoblastomycosis, and disseminated infections were excluded. Results. Eighteen cases were analyzed. The median age was 60.5 years. In all cases, patients originated from tropical or subtropical areas. An underlying immunodepression was present in 89% of cases. Cutaneous and/or subcutaneous lesions, mainly nodules, abscesses, or infiltrated plaques, were observed in distal body areas. Isolates of different genera of coelomycetes were identified: Medicopsis (6), Paraconiothyrium (3), Gloniopsis (3), Diaporthe (3), Peyronellaea (2), Lasiodiplodia (1). Lesion treatment consisted of complete (10) or partial (2) surgical excision and/or the use of systemic antifungal therapy, namely voriconazole (5) and posaconazole (4). Literature review yielded 48 additional cases of cutaneous and/or subcutaneous infections due to coelomycetes. Conclusions. Infectious diseases physicians should suspect coelomycetes when observing cutaneous and/or subcutaneous infections in immunocompromised hosts from tropical areas; a sequence-based approach is crucial for strains identification but must be supported by consistent phenotypic features; surgical treatment should be favored for solitary, well limited lesions; new triazoles may be used in case of extensive lesions, especially in immunocompromised patients.

    One hundred and forty episodes in 112 patients (58 boys) with diabetic ketoacidosis (96 episodes) and diabetic ketosis (44 episodes) were studied to elucidate the clinical and laboratory risk factors for altered level of consciousness at presentation and to analyze the outcome of a distinct protocol in the treatment of diabetic ketoacidosis. The patients were analyzed according to demographic data and clinical and laboratory findings at admission. The treatment protocol involved use of 0.45% sodium chloride (NaCl) in 2.5% dextrose as the initial fluid therapy following volume expansion. Dextrose content of the fluid was doubled once the serum glucose level fell below 250 mg/dl. The mean ages at presentation with diabetic ketoacidosis and ketosis were 10.3 +/- 4.4 and 10.2 +/- 4.0 years, respectively. Thirty-one percent of patients had altered consciousness at presentation. The level of consciousness correlated negatively with serum bicarbonate level (r=-0.485; p<0.001). A serum bicarbonate level below 15 mmol/L was a risk factor for altered consciousness. There was no correlation between effective osmolality and the level of consciousness. Serum effective osmolality above 320 mOsm/kg H2O did not appear to be a risk factor for altered consciousness. No mortality or any signs of clinical brain edema were observed in patients treated with the distinct treatment protocol. In conclusion, acidosis appears to be the major factor in the pathogenesis of altered consciousness at presentation. Serum effective osmolality does not seem to be a risk factor as suggested previously. Dextrose added to the infusion fluid early in treatment seems to prevent the development of brain edema, and this may be due to a protective effect of higher osmolality in the resultant solution.

    A large-scale lifetime building monitoring program was implemented in Singapore in 2001. The monitoring aims of this unique program were to increase safety, verify performance, control quality, increase knowledge, optimize maintenance costs, and evaluate the condition of the structures after a hazardous event. The first instrumented building, which has now been monitored for more than ten years, is presented in this paper. The long-gauge fiber optic strain sensors were embedded in fresh concrete of ground-level columns, thus the monitoring started at the birth of both the construction material and the structure. Measurement sessions were performed during construction, upon completion of each new story and the roof, and after the construction, i.e., in-service. Based on results it was possible to follow and evaluate long-term behavior of the building through every stage of its life. The results of monitoring were analyzed at a local (column) and global (building) level. Over-dimensioning of one column was identified. Differential settlement of foundations was detected, localized, and its magnitude estimated. Post-tremor analysis was performed. Real long-term behavior of concrete columns was assessed. Finally, the long-term performance of the monitoring system was evaluated. The researched monitoring method, monitoring system, rich results gathered over approximately ten years, data analysis algorithms, and the conclusions on the structural behavior and health condition of the building based on monitoring are presented in this paper.

    2011-01-01

    Background There is little information regarding the trends in body mass index (BMI) and obesity in the overall Portuguese population, namely if these trends are similar according to educational level. In this study, we assessed the trends in the prevalence of overweight and obesity in the Portuguese population, overall and by educational level. Methods Cross-sectional national health interview surveys conducted in 1995-6 (n = 38,504), 1998-9 (n = 38,688) and 2005-6 (n = 25,348). Data were derived from the population and housing census of 1991 and two geographically-based strata were defined. The sampling unit was the house, and all subjects living in the sampling unit were surveyed. Height and weight were self-reported; the effects of gender, age group and educational level were also assessed by self-reported structured questionnaires. Bivariate comparisons were performed using Chi-square or analysis of variance (ANOVA). Trends in BMI levels were assessed by linear regression analysis, while trends in the prevalence of obesity were assessed by logistic regression. Results Mean (±standard deviation) BMI increased from 25.2 ± 4.0 in 1995-6 to 25.7 ± 4.5 kg/m2 in 2005-6. Prevalence of overweight remained stable (36.1% in 1995-6 and 36.4% in 2005) while prevalence of obesity increased (11.5% in 1995-6 and 15.1% in 2005-6). Similar findings were observed according to age group. Mean age-adjusted BMI increase (expressed in kg/m2/year and 95% confidence interval) was 0.073 (0.062, 0.084), 0.016 (0.000, 0.031) and 0.073 (0.049, 0.098) in men with primary, secondary and university levels, respectively; the corresponding values in women were 0.085 (0.073, 0.097), 0.052 (0.035, 0.069) and 0.062 (0.038, 0.084). Relative to 1995-6, obesity rates increased by 48%, 41% and 59% in men and by 40%, 75% and 177% in women with primary, secondary and university levels, respectively. The corresponding values for overweight were 6%, 1% and 23% in men and 5%, 7% and 65% in women

    In the 10 years that Cassini has been orbiting Saturn, a wealth of observations have been returned that have probed a wide range of altitudes in Saturn's atmosphere from <1 microbar to roughly 3 bars. Radar and 5-micron VIMS images reveal spectacular cloud structure at the 3-bar level. ISS, CIRS, and VIMS probe the upper troposphere where storms originate. CIRS probes the stratosphere and upper troposphere, while UVIS sounds the stratosphere and mesosphere. Some of the highlights include: 1) the Great Northern Storm of 2010-2011. This planet-encircling storm is believed to have originated in the water cloud (P>10 bars) with dramatic effects on the cloud structure in the upper troposphere (0.5 bars), and, quite surprisingly, the generation of localized heated regions in Saturn's stratosphere near 2 mbars. Cassini's full instrument complement was used to study the storm, leading to the detection of fresh ammonia ice in the troposphere and enhanced temperatures and hydrocarbons, such as ethylene, in the stratosphere. 2) The detection of hurricane-like features at both the North and South Pole of Saturn. These exhibit interesting structure at the spatial resolution of ISS and VIMS, while CIRS has detected enhanced temperatures at both poles. 3) The persistence of the Northern Hexagon at 79N. This 6-sided feature was detected by Voyager and it has been studied by the full suite of Cassini remote sensing instruments. It is detectable as a warm region at 100 mbars, but there is no thermal signature in the stratosphere. 4) Seasonal reversal of photochemically produced aerosols. When Cassini arrived at Saturn, the winter northern hemisphere appeared blue, while the southern hemisphere exhibited an orange appearance. Shortly after equinox in 2009, the appearance reversed quite abruptly. During the last stage of the mission in 2016-2017, Cassini will obtain measurements at very high spatial resolution during the F-ring and Proximal orbits. The Ion and Neutral Mass

  17. Hidden geometry of traffic jamming

    We introduce an approach based on algebraic topological methods that allow an accurate characterization of jamming in dynamical systems with queues. As a prototype system, we analyze the traffic of information packets with navigation and queuing at nodes on a network substrate in distinct dynamical regimes. A temporal sequence of traffic density fluctuations is mapped onto a mathematical graph in which each vertex denotes one dynamical state of the system. The coupling complexity between these states is revealed by classifying agglomerates of high-dimensional cliques that are intermingled at different topological levels and quantified by a set of geometrical and entropy measures. The free-flow, jamming, and congested traffic regimes result in graphs of different structure, while the largest geometrical complexity and minimum entropy mark the edge of the jamming region.

  18. Geomagnetic response to solar activity: summary for the last ten years and analysis of selected cases

    The main sources of geomagnetic disturbances are either coronal mass ejections (CMEs), which are usually connected with eruptive flares, or high-speed streams of solar wind from coronal holes. Development of an eruptive flare and ejection of coronal mass is accompanied by magnetic reconnection. The evidence of reconnection can be found in a broad spectrum of observations. The observations of X-rays and radio bursts were used in our study. The geoeffectiveness of solar X-ray flares was initially analysed on data from the period 1996 - 2004 [1]. It was shown that the probability of geomagnetic response depends on the solar flare class and its position on the solar disc. The flares in the central region were found to be more geoeffective. The probability further increased if the flare was accompanied by Type II and/or Type IV of solar radio bursts. In the next step a neural network model was developed to determine the probability, with which flares will be followed by the geomagnetic response of a particular intensity. Enhancement of solar energetic particle flux was added to the set of input parameters. The results indicated that X-ray flares accompanied by solar radio bursts represent a good proxy of CMEs [2, 3]. This conclusion was now confirmed by the data from the period 2005 - 2012. Coronal holes are stable formations that can survive over several solar rotations. Corotating interaction regions (CIRs) between fast and slow solar wind can thus periodically pass over the Earth and cause recurrent geomagnetic storms. This periodicity makes the forecasts of the geomagnetic disturbances much easier [4] than in the case of eruptive phenomena. Our analysis confirmed that the strongest magnetic storms are caused by CMEs. Nevertheless, many geomagnetic disturbances in the active part of solar cycle are influenced by sequences of CMEs and CIRs, which increase their strength. [1] Bochníček, J., P. Hejda and F.

Prior evaluation included treatment for upper airway cough syndrome and gastroesophageal reflux, stopping angiotensin-converting enzyme inhibitor, and initiation of inhaled β-agonists. Esophageal pH monitoring indicated silent reflux, and proton pump inhibitor therapy was started. He continued to cough and complain of dyspnea. Physical examination produced unremarkable results, with no evidence of lymphadenopathy. Pulmonary function tests showed a pseudo-restrictive pattern with air trapping, hyperreactivity, and incomplete bronchodilator responsiveness: FEV1, 2.48 L (69% of predicted); FVC, 3.57 L (75% of predicted); FEV1/FVC, 92%; total lung capacity, 7.00 L (100% of predicted); and residual volume, 3.05 L (136% of predicted). Laboratory studies, including a complete metabolic panel, prostate-specific antigen test, and complete blood count, yielded normal results.

    Galeazzi fractures represent approximately 3 to 6 percent of forearm fractures, whereas Monteggia fractures represent 1 to 2 percent. The combination of these injuries in the same extremity is an exceedingly rare occurrence. We report a case of ipsilateral combination of Galeazzi and Monteggia fractures in a ten-year-old patient. The patient was treated with closed reduction and internal fixation with Kirschner pins. The distal radioulnar and radiocapitellar joint relationships were restored and the fractures healed. The patient proceeded to obtain a satisfactory functional result three years later. Internal fixation is a safe method for such complex forearm fractures in older children and allows post-operative rehabilitation with the advantage of early mobilization.

    Sediments, clams Scrobicularia plana and worms Hediste diversicolor from the Guadalquivir estuary were collected ten years after the Aznalcóllar mine spill and analyzed for metals. Significant seasonal and spatial effects were detected for most elements, so data from different sampling periods and locations were treated separately. Overall, the most polluted sites were found upstream, although Zn and Cu tended to accumulate at the estuary mouth. A significant decline of Zn in sediments and clams was observed compared to levels reported following the spill, so the estuarine ecosystem has recovered. However, the concentrations of some elements in S. plana were still higher than those of heavily contaminated regions. In this mollusk, Pb and As levels were higher in 2008 than in previous years, suggesting a new source entering into the estuary. Metals in sediments presented low bioavailability for biota, so other sources must account for the concentrations observed in these species. PMID:25048729

    Flow in magnetorheological (MR) fluids and systems near jamming both display hallmarks of complex fluid rheology, including yield stresses and shear thinning viscosities. They are also tunable, which means that both phenomena can be used as a switching mechanism in ``smart'' fluids, i.e. fluids where properties can be tuned rapidly and reversibly by changing external parameters. We use numerical simulations to investigate the rheological properties of MR fluids close to the jamming transition as a function of the applied field and volume fraction. We are especially interested in the crossover region where both phenomena are needed to describe the observed dynamics. Funded by the Dutch Organization for Scientific Research (NWO).

  4. Mobility of large woody debris (LWD) jams in a low gradient channel

    NASA Astrophysics Data System (ADS)

    Curran, Joanna C.

    2010-04-01

    Mobility of large woody debris (LWD) in low gradient channels is an important but often overlooked transport process. The majority of studies on LWD have focused on its role in geomorphic and ecologic river processes. When jams extend across the width of the channel, they have the potential to retain sediment and alter the channel profile. When jams obstruct only a portion of the channel, they can re-direct flow, altering patterns of scour and deposition. The boundary complexity created by LWD has a recognized role in riverine ecosystems which has led to programs of replacing LWD in-channel corridors where it was previously removed. Although LWD jams are common in rivers around the world, they have been studied most intensely in steep, forested channel reaches where they are often found to be stable channel features. It is not fully known how much of the information on LWD from steep forested channels will transfer to other channel types. Whereas it may be reasonable to assume that the ecological benefits of LWD are similar in low gradient channels, research has shown that a much higher rate of LWD transport occurs in low gradient channels, with jams mobilized on timescales of 10 0-10 2 years. This study evaluates the distribution and mobility of LWD over 72 km of the San Antonio River, a low gradient channel in southeast Texas. LWD jam locations were identified for 2003 and 2007 using a combination of aerial photography and field mapping. Each jam was cataloged according to its location in the channel cross-section and the amount of channel area blocked. During the four-year period, all the LWD jams were mobilized, including those jams extending across the channel width. Although easily mobilized, 34 jams re-form in the same locations, creating 34 channel locations with persistent LWD jams. Data from the San Antonio River are applied to two models developed to predict LWD mobility and transport distances to assess the applicability of each model to a low gradient

    As was amply demonstrated during the EU/IAEA/WHO Summing-up-Conference in Vienna, Austria, April 8-12, 1996, the radiological consequences of the Chernobyl accident were, fortunately, not as serious as frequently presented in the media: 28 people died from acute radiation syndrome in 1986, 14 more of possibly radiation-related causes since. Of the <1000 thyroid cancers in children, 90 to 95% are curable. There have so far been no other demonstrable increases in the former Soviet Union, as well as in Western Europe, of leukemias, solid cancers, or genetic defects, nor are any to be expected in the future. Even among the {open_quotes}liquidators{close_quotes} with doses {approximately}100 mSv, of the {approximately}150 additional expected leukemias during the 10 yr after the accident, none have been observed. The economical, social, and political consequences, however, both in the former Soviet Union and in Western Europe, have been very substantial. Whole countries developed an hysterical `radiation sickness.` As A. Merkel, the German Minister of Environment and Reactor Safety, who chaired the conference, pointed out, `the radiation sensitivity of societies far exceeds that of individuals.` It is obvious that important groups in Ukraine, Belaurus, and Russia try to blame a large fraction of all economic, social, and health problems during the last decade, which are substantial ({approx} 6 yr less life expectancy, twice the homicides and traffic deaths, increased alcoholism, and so forth), on radiation of the Chernobyl accident in an effort to attract more support. Western scientists refute such claims but admit large non-radiation-related problems caused by the accident.

    High latitude peatlands constitute about 3% of the global land cover but store almost a third of the global soil carbon pool. The annual net ecosystem carbon balance at high latitude mires results from the balance between net ecosystem exchange, methane emission and stream discharge export. Understanding stream carbon export dynamics is needed to accurately predict how the carbon balance of peatlands will respond to climatic and environmental change. We use a ten year record (2004-2014) of streamflow and dissolved carbon (DOC, DIC, and CH4) measurements to assess interannual and seasonal variability in stream carbon export for a peatland catchment in northern Sweden. Mean annual total carbon export for the ten year period was 11.4 gC/m2, but individual years ranged between 6.1 and 17.2 gC/m2. DOC was the dominant form of carbon being exported, comprising 68% to 76% of total annual exports, and DIC contributed between 24% and 30%. CH4 made up less than 3% of total export. Stream carbon export and streamflow were highly synchronous. The majority of export (30% to 55% of annual totals) occurred during the spring snowmelt period. Exports during the summer and autumn were highly variable (1% to 45% and 9% to 53% of annual totals, respectively) and depended on the timing and magnitude of rain events. Winter periods were characterized by low streamflow conditions and associated low carbon export (0.6% to 10% of annual totals). These results highlight considerable interannual and seasonal variability of stream carbon export driven primarily by rain and snowmelt runoff events.

    Background Early HIV diagnosis and enrolment in care is needed to achieve early antiretroviral treatment (ART) initiation. Studies on HIV disease stage at enrolment in care from Asian countries are limited. We evaluated trends in and factors associated with late HIV disease presentation over a ten-year period in the largest ART center in Cambodia. Methods We conducted a retrospective analysis of program data including all ARV-naïve adults (> 18 years old) enrolling into HIV care from March 2003-December 2013 in a non-governmental hospital in Phnom Penh, Cambodia. We calculated the proportion presenting with advanced stage HIV disease (WHO clinical stage IV or CD4 cell count <100 cells/μL) and the probability of ART initiation by six months after enrolment. Factors associated with late presentation were determined using multivariate logistic regression. Results From 2003–2013, a total of 5642 HIV-infected patients enrolled in HIV care. The proportion of late presenters decreased from 67% in 2003 to 44% in 2009 and 41% in 2013; a temporary increase to 52% occurred in 2011 coinciding with logistical/budgetary constraints at the national program level. Median CD4 counts increased from 32 cells/μL (IQR 11–127) in 2003 to 239 cells/μL (IQR 63–291) in 2013. Older age and male sex were associated with late presentation across the ten-year period. The probability of ART initiation by six months after enrolment increased from 22.6% in 2003–2006 to 79.9% in 2011–2013. Conclusion Although a gradual improvement was observed over time, a large proportion of patients still enroll late, particularly older or male patients. Interventions to achieve early HIV testing and efficient linkage to care are warranted. PMID:26606057

    In this prospective study, teenager mothers (mean age = 16; range = 12–18; 70% African American) were interviewed about their tobacco use during pregnancy. When their children were ten, mothers reported on their child’s behavior and the children completed a neuropsychological battery. We examined the association between prenatal cigarette smoke exposure (PCSE) and offspring neurobehavioral outcomes on data from the ten-year phase (n = 336). Multivariate regression analyses were conducted to test if PCSE predicted neurobehavioral outcomes, adjusting for demographic characteristics, maternal psychological characteristics, prenatal exposure to other substances, and exposure to environmental tobacco smoke. Independent effects of PCSE were found. Exposed offspring had more delinquent, aggressive and externalizing behaviors (CBCL). They were more active (Routh, EAS, SNAP) and impulsive (SNAP), and had more problems with peers (SNAP). On the Stroop test, deficits were observed in both baseline response processing measures and on the more complex interference task that requires both selective attention and response inhibition. The significant effects of PCSE on neurobehavioral outcomes were found for exposure to as few as 10 cigarettes per day. These results are consistent with results from an earlier assessment when the children were age 6, demonstrating that the effects of prenatal tobacco exposure can be identified early and are consistent through middle childhood.

    Objective To determine the effects of cognitive training on cognitive abilities and everyday function over 10 years. Design, Setting, and Participants Ten-year follow-up of a randomized, controlled single-blind trial with 3 intervention groups and a no-contact control group. A volunteer sample of 2832 persons (mean baseline age, 73.6 years; 26% African American) living independently in 6 US cities. Interventions Ten-session training for memory, reasoning, or speed-of-processing.; 4-session booster training at 11 and at 35 months after training. Measurements Objectively measured cognitive abilities and self-reported and performance-based measures of everyday function. Results Participants in each intervention group reported less difficulty with instrumental activities of daily living (IADL) (memory: effect size, 0.48 [99% CI, 0.12-0.84]; reasoning: effect size, 0.38 [99% CI, 0.02-0.74]; speed-of-processing: effect size, 0.36 [99% CI, 0.01-0.72]). At mean age of 82 years, about 60% of trained participants compared to 50% of controls (p<.05) were at or above their baseline level of self-reported IADL function at 10 years. The reasoning and speed-of-processing interventions maintained their effects on their targeted cognitive abilities at 10 years (reasoning: effect size, 0.23 [99% CI, 0.09-0.38]; speed-of-processing: effect size, 0.66 [99% CI, 0.43-0.88]). Memory training effects were no longer maintained for memory performance. Booster training produced additional and durable improvement for the reasoning intervention for reasoning performance (effect size, 0.21 [99% CI, 0.01-0.41]) and the speed-of-processing intervention for speed-of-processing performance (effect size, 0.62 [99% CI, 0.31-0.93]). Conclusions Each ACTIVE cognitive intervention resulted in less decline in self-reported IADL compared with the control group. Reasoning and speed, but not memory, training resulted in improved targeted cognitive abilities for 10 years. PMID:24417410

    OBJECTIVE: To compare treatment patterns and the ten-year survival of prostate cancer patients in two large, nonprofit, group/staff HMOs to those of patients receiving care in the fee-for-service health setting. DATA SOURCES/STUDY DESIGN: A cohort of men age 65 and over diagnosed with prostate cancer between 1985 and the end of 1992 and followed through 1994. Subjects (n = 21,741) were ascertained by two population-based tumor registries covering the greater San Francisco-Oakland and Seattle-Puget Sound areas. Linkage of registry data with Medicare claims data and with HMO inpatient utilization data allowed the determination of health plan enrollment and the measurement of comorbid conditions. Multivariate regression models were used to examine HMO versus FFS treatment and survival differences adjusting for sociodemographic and clinical characteristics. PRINCIPAL FINDINGS: Among cases with non-metastatic prostate cancer, HMO patients were more likely than FFS patients to receive aggressive therapy (either prostatectomy or radiation) in San Francisco-Oakland (odds ratio [OR] = 1.69, 95% CI = 1.46-1.96) but not in Seattle (OR = 1.15, 0.93-1.43). Among men receiving aggressive therapy, HMO cases were three to five times more likely to receive radiation therapy than prostatectomy. Overall mortality was equivalent over ten years (HMO versus FFS mortality risk ratio [RR] = 1.01, 0.94-1.08), but prostate cancer mortality was higher for HMO cases than for FFS cases (RR = 1.25, 1.13-1.39). CONCLUSION: Despite marked treatment differences for clinically localized prostate cancer, overall ten-year survival for patients enrolled in two nonprofit group/staff HMOs was equivalent to survival among patients receiving care in the FFS setting, even after adjustment for sociodemographic and clinical characteristics. Similar overall but better prostate cancer-specific survival among FFS patients is most plausibly explained by differences between the HMO and FFS patients in both tumor

    The sonar systems of bats and dolphins are in many ways superior to man-made sonar and radar systems, and considerable effort has been devoted to understanding the signal-processing strategies underlying these capabilities. A major feature determining the efficiency of sonar systems is the sensitivity to noise and jamming signals. Previous studies indicated that echolocating bats may adjust their signal structure to avoid jamming ('jamming avoidance response'; JAR). However, these studies relied on behavioural correlations and not controlled experiments. Here, we provide the first experimental evidence for JAR in bats. We presented bats (Tadarida brasiliensis) with 'playback stimuli' consisting of recorded echolocation calls at one of six frequencies. The bats exhibited a JAR by shifting their call frequency away from the presented playback frequency. When the approaching bats were challenged by an abrupt change in the playback stimulus, they responded by shifting their call frequencies upwards, away from the playback. Interestingly, even bats initially calling below the playback's frequency shifted their frequencies upwards, 'jumping' over the playback frequency. These spectral shifts in the bats' calls occurred often within less than 200 ms, in the first echolocation call emitted after the stimulus switch-suggesting that rapid jamming avoidance is important for the bat.

    Background In Spain, more than 85% of coronary heart disease deaths occur in adults older than 65 years. However, coronary heart disease incidence and mortality in the Spanish elderly have been poorly described. The aim of this study is to estimate the ten-year incidence and mortality rates of myocardial infarction in a population-based large cohort of Spanish elders. Methods A population-based cohort of 3729 people older than 64 years old, free of previous myocardial infarction, was established in 1995 in three geographical areas of Spain. Any case of fatal and non-fatal myocardial infarction was investigated until December 2004 using the "cold pursuit method", previously used and validated by the the WHO-MONICA project. Results Men showed a significantly (p < 0.001) higher cumulative incidence of myocardial infarction (7.2%; 95%CI: 5.94-8.54) than women (3.8%; 95%CI: 3.06-4.74). Although cumulative incidence increased with age (p < 0.05), gender-differences tended to narrow. Adjusted incidence rates were higher in men (957 per 100 000 person-years) than in women (546 per 100 000 person-years) (p < 0.001) and increased with age (p < 0.001). The increase was progressive in women but not in men. Adjusted mortality rates were also higher in men than in women (p < 0.001), being three times higher in the age group of ≥ 85 years old than in the age group of 65-74 years old (p < 0.001). Conclusion Incidence of fatal and non-fatal myocardial infarction is high in the Spanish elderly population. Men show higher rates than women, but gender differences diminish with age. PMID:19778417

    About a decade ago, psychology of the arts started to gain momentum owing to a number of drives: technological progress improved the conditions under which art could be studied in the laboratory, neuroscience discovered the arts as an area of interest, and new theories offered a more comprehensive look at aesthetic experiences. Ten years ago, Leder, Belke, Oeberst, and Augustin (2004) proposed a descriptive information-processing model of the components that integrate an aesthetic episode. This theory offered explanations for modern art's large number of individualized styles, innovativeness, and for the diverse aesthetic experiences it can stimulate. In addition, it described how information is processed over the time course of an aesthetic episode, within and over perceptual, cognitive and emotional components. Here, we review the current state of the model, and its relation to the major topics in empirical aesthetics today, including the nature of aesthetic emotions, the role of context, and the neural and evolutionary foundations of art and aesthetics.

    Brain metastasis are the most common neoplastic lesions of the nervous system. Many cancer patients are diagnosed on the basis of a first clinical presentation of cancer on the basis of a single or multiple brain lesions. Brain metastases are manifestations of primary disease progression and often determine a poor prognosis. Not all patients with a brain metastases undergo surgery: many are submitted to alternative or palliative treatments. Management of patients with brain metastases is still controversial, and many studies have been developed to determine which is the best therapy. Furthermore, management of patients operated for a brain metastasis is often difficult. Chemotherapy, stereotactic radiosurgery, panencephalic radiation therapy, and surgery, in combination or alone, are the means most commonly used. We report our experience in the management of a ten-year series of surgical brain metastasis and discuss our results in the preoperative and postoperative management of this complex condition.

    The biologic drugs bevacizumab and ranibizumab have revolutionized treatment of diabetic macular edema and macular degeneration, leading causes of blindness. Ophthalmologic use of these drugs has increased, now accounting for roughly one-sixth of the Medicare Part B drug budget. Ranibizumab and bevacizumab have similar efficacy and potentially minor differences in adverse event rates, but at $2,023 per dose, ranibizumab costs forty times more than bevacizumab. Using modeling methods, we predict ten-year (2010–2020) population-level costs and health benefits of using bevacizumab and ranibizumab. Our results show that if all patients were treated with the less-expensive bevacizumab instead of current usage patterns, Medicare Part B, patients, and the health care system would save $18 billion, $4.6 billion, and $29 billion, respectively. Altering patterns of use with these therapies by encouraging bevacizumab use and hastening approval of biosimilar therapies would dramatically reduce spending without substantially affecting patient outcomes.

    Recent public health threats have propelled major innovations on infectious disease monitoring, culminating in the development of innovative syndromic surveillance methods. Influenzanet is an internet-based system that monitors influenza-like illness (ILI) in cohorts of self-reporting volunteers in European countries since 2003. We investigate and confirm coherence through the first ten years in comparison with ILI data from the European Influenza Surveillance Network and demonstrate country-specific behaviour of participants with ILI regarding medical care seeking. Using regression analysis, we determine that chronic diseases, being a child, living with children, being female, smoking and pets at home, are all independent predictors of ILI risk, whereas practicing sports and walking or bicycling for locomotion are associated with a small risk reduction. No effect for using public transportation or living alone was found. Furthermore, we determine the vaccine effectiveness for ILI for each season. PMID:26616039

    1995-10-01

    Ten years of flaps represent a little and a lot. It is little compared to the 2600 years since the first flap in plastic surgery: the Susruta Indian flap, but it is a lot in view of the phenomenal acceleration of this speciality since the Second World War. In 1994 alone, more than two hundred references are listed under the heading "new flaps". As it is impossible to be exhaustive, the author has chosen to focus on two main aspects: a theoretical review of new transfer techniques, dealing successively with: the principles of reverse flow flaps, venous flaps, neurocutaneous flaps, so-called "extracorporeal" transfers, reverse flow YV technique; and practical aspects based on a review of eighteen autoplasties or donor sites selected for their surgical value, their reproductibility and their innovative nature. The author's objective is not to present a technical treatise, but rather to make the reader aware of several key points or even, in some cases, the very existence of these autoplasties. This paper is designed to be didactic, with extensive references, in order to act as a practical guide. It also demonstrates, as if there were any need, to what extent plastic surgery is able to create new solutions and the essential value of continuing research.

    This longitudinal study investigated how chronic gunshot noise exposure affects cochlear and saccular function in police officers who engaged in regular target shooting practice using dual protection (ear plugs plus earmuffs) for >10 years. In 1997, 20 male police officers underwent audiometry before and two weeks after shooting. Twelve of the original subjects were re-examined by audiometry coupled with vestibular evoked myogenic potential (VEMP) test in 2007. Significant deterioration of mean hearing thresholds at frequencies of 500 Hz through 4000 Hz was noted ten years later, affecting both ears. However, only the frequencies of 4000 and 6000 Hz on the left ear revealed significant difference in mean hearing thresholds compared with healthy controls. Abnormal VEMP responses were evident in nine police officers (75%), including absent VEMPs 7 and delayed VEMPs 2. In conclusion, deterioration to hearing may occur after long term exposure to gunshots, even when double hearing protection is used. Further study is in progress regarding how to preserve both cochlear and saccular function during long term gunshot exposure. PMID:19925337

    Background: Klity Creek has become Thailand’s first official remediation ordered by the court in 2013, 15 years after the spill of lead (Pb)-contaminated mine tailing into the creek. The Pollution Control Department (PCD) decided to restore the creek through monitored natural recovery (MNR) since 2006 but has not been successful. Interestingly, the most recent remediation plan in 2015 will still apply MNR to five out of the seven portions of the creek, despite no scientific feasibility evaluation of using MNR to restore the creek. Objective: This study qualitatively and quantitatively evaluated the feasibility of using MNR to clean up the creek in order to protect the Klity children from excess Pb exposure. Methods: We analyzed the physical and chemical transformation of Pb contaminated sediment in the creek and developed a remedial action goal and cleanup level using the Integrated Exposure Uptake Biokinetic model (IEUBK). We empirically determined the natural recovery (NR) potentials and rates using 10 years of data monitoring the water and sediment samples from eight monitoring stations (KC1 to KC8). Results: Klity Creek has NR potential for water except at KC2, which is closest to the spill and the other improperly managed Pb sources. However, the creek has no NR potential for sediment except at the KC8 location (NR rate = 11.1 ± 3.0 × 10–3 month–1) farthest from the spill. Conclusion: The MNR method is not suitable to use as the sole remedial approach for Klity Creek (KC2 to KC7). Although MNR is applicable at KC8, it may require up to 377 ± 76 years to restore the sediment to the background Pb concentration. Citation: Phenrat T, Otwong A, Chantharit A, Lowry GV. 2016.

    Empirical and numerical microscopic features of moving traffic jams are presented. Based on a single vehicle data analysis, it is found that within wide moving jams, i.e., between the upstream and downstream jam fronts there is a complex microscopic spatiotemporal structure. This jam structure consists of alternations of regions in which traffic flow is interrupted and flow states of low speeds associated with “moving blanks” within the jam. Moving blanks within a wide moving jam resemble electron holes in the valence band of semiconductors: As the moving blanks that propagate upstream appear due to downstream vehicle motion within the jam, so appearance of electron holes moving with the electric field results from electron motion against the electric field in the valence band of semiconductors. Empirical features of moving blanks are found. Based on microscopic models in the context of the Kerner’s three-phase traffic theory, physical reasons for moving blanks emergence within wide moving jams are disclosed. Microscopic nonlinear effects of moving jam emergence, propagation, and dissolution as well as a diverse variety of hysteresis effects in freeway traffic associated with phase transitions and congested traffic propagation are numerically investigated. Microscopic structure of moving jam fronts is numerically studied and compared with empirical results.

    Objective To examine the long term effect of donor diabetes history on graft failure and endothelial cell density (ECD) after penetrating keratoplasty (PKP) in the Cornea Donor Study Design Multi-center prospective, double-masked, controlled clinical trial Participants 1090 subjects undergoing PKP for a moderate risk condition, principally Fuchs’ dystrophy or pseudophakic/aphakic corneal edema (PACE), were enrolled by 105 surgeons from 80 clinical sites in the United States. Methods Corneas from donors 12 to 75 years old were assigned by 43 eye banks to participants without respect to recipient factors. Donor and recipient diabetes status was determined from existing medical records. Images of the central endothelium were obtained preoperatively (baseline) and at intervals for ten years postoperatively and analyzed by a central image analysis reading center to determine ECD. Main Outcome Measure(s) Time to graft failure (regraft or cloudy cornea for 3 consecutive months) and ECD. Results There was no statistically significant association of donor diabetes history with 10-year graft failure, baseline ECD, 10-year ECD or ECD values longitudinally over time in unadjusted analyses nor after adjusting for donor age and other significant covariates. The 10-year graft failure rate was 23% in the 199 cases receiving a cornea from a donor with diabetes versus 26% in the 891 cases receiving a cornea from a donor without diabetes (95% confidence interval for the difference: −10% to +6%; unadjusted p = 0.60). Baseline ECD (p=0.71), 10-year ECD (p>0.99), and changes in ECD over 10 years (p=0.86) were similar comparing donor diabetes and no-diabetes groups. Conclusions and Relevance The study results do not suggest an association between donor diabetes and PKP outcome. However, the assessment of donor diabetes was imprecise and based on historical data only. The increasing frequency of diabetes in the aging population in the United States affects the donor pool, thus the

    Despite the appearance of simplicity, much of the behavior of granular materials remains mysterious. One intriguing puzzle is the dynamical mechanism underlying the ``jamming'' transition, in which disordered grains become rigid at high density. By applying nonlinear dynamical techniques to simulated 2D shear cells, we reveal the mechanisms of jamming and find they conflict with the prevailing picture of growing cooperative regions. Additionally, at the density corresponding to random close packing, we find a dynamical transition from chaotic to non-chaotic states accompanied by diverging dynamical length and time scales. Furthermore, we find that the dominant cooperative dynamical modes are strongly correlated with particle rearrangements and become increasingly unstable before stress jumps, providing a way to predict the times and locations of these earthquake-like stress-release events.

    Objectives: To study the clinical presentation and treatment outcome of molar pregnancy at a Tertiary Care Hospital in Dammam, Saudi Arabia. Materials and Methods: Reviewed medical records of all molar pregnancy cases among all the deliveries at a tertiary care hospital in Dammam from 2005 to 2014, after approval by institutional ethical review committee. Data abstracted included patient's age, parity, presenting symptoms, gestational age at diagnosis, uterine size, ultrasonographic findings, BhCG level at the time of diagnosis and at follow-up after evacuation, and blood loss during evacuation. Data was entered and analyzed using Excel; frequency distribution for categorical variables and descriptive statistics for continuous variables were computed. Results: Of a total of 25,000 deliveries in ten years, 22 cases of complete molar pregnancy were encountered: 0.9 cases of molar pregnancy per 1000 pregnancies. Majority of patients (63.7%) were older than 35 years, and were nulliparous (45.5%). The commonest symptom was vaginal bleeding (86.4%) followed by hyperemesis gravidarum (41.0%); Hyperthyroidism was seen in 1 patient (4.5%). Ovarian enlargement by theca-lutin cyst was seen in 3 patients (13.6%). The majority of patients (63.6%) had normal BhCG within 9 weeks (63 days) after suction curettage. The majority of the cases followed a benign course. Conclusion: Aged older than 35 years seems a risk factor and vaginal bleeding is the commonest presenting symptom. Early booking of pregnant women to antenatal care clinics and routine first trimester ultrasound made diagnosis easier and earlier before complications appear. PMID:27625583

    For the period 1996-2006, global distributions of tropospheric nitrogen dioxide (NO2) have been derived from radiances measured with the satellite instruments GOME (Global Ozone Monitoring Experiment) and SCIAMACHY (SCanning Imaging Absorption spectroMeter for Atmospheric CartograpHY). A statistical analysis is applied to derive trends and seasonal variability for this period on a global scale. The time series of the monthly NO2 columns for these ten years have been fitted with a linear function superposed on an annual seasonal cycle on a grid with a spatial resolution of 1° by 1°. We see significant reductions (up to 7% per year) in NO2 in Europe and parts of the eastern United States, and a strong increase in Asia, most particularly in China (up to 29% per year) but also in Iran and Russia. By comparing the data with the cloud information derived from the same satellite observations, the contribution of lightning to the total column of NO2 is estimated. The estimated NO2 from lightning is, especially in the tropics, in good agreement with lightning flash rate observations from space. The satellite observed seasonal variability of NO2 generally correlates well with independent observations and estimates of the seasonal cycle of specific NOx sources. Source categories considered are anthropogenic (fossil fuel and biofuel), biomass burning, soil emissions and lightning. Using the characteristics of the seasonal variability of these source categories, the dominant source of NOx emissions has been identified on a global scale and on a 1° by 1° grid.

  8. Jamming transition in hierarchical networks

    2014-03-01

    Jamming transitions arise in disordered granular materials where the systems fall out of equilibrium due to an increase in the packing density. A kinetically constrained lattice gas model due to Biroli and Mezard (BM) has connected the jamming transition to an equilibrium phase transition. In this description, before this equilibrium transition can be reached, any experiment or simulation would fall out of equilibrium at a Kauzmann transition. However, this analysis is based on a mean-field calculation which, for disordered systems, may have limited relevance in finite dimensions. We study the BM-model on a lattice-like network, which mixes geometric and mean-field features, to reproduce such a phase transition. Computationally, we use the Wang-Landau algorithm which should be less affected by the jamming near the phase transition. The algorithm produces the density of states and, hence, the entropy directly, in addition to many critical properties, such as packing fraction, compressibility, etc. Also, lattice-like hierarchical networks conveniently allow exact or approximate renormalization group treatments, extending analytical results to the thermodynamic limit.

    2013-06-01

    Everyday life tells us that matter acquires rigidity either when it cools down, like lava flows which turn into solid rocks, or when it is compacted, like tablets simply formed by powder compression. As suggested by these examples, solidification is not the sole privilege of crystals but also happens for disordered media such as glass formers, granular media, foams, emulsions and colloidal suspensions. Fifteen years ago the "Jamming paradigm" emerged to encompass in a unique framework the glass transition and the emergence of yield stress, two challenging issues in modern condensed matter physics. One must realize how bold this proposal was, given that the glass transition is a finite temperature transition governing the dynamical properties of supercooled liquids, while Jamming is essentially a zero temperature, zero external stress and purely geometric transition which occurs when a given packing of particles reaches the maximum compression state above which particles start to overlap. More recently, the observation of remarkable scaling properties on the approach to jamming led to the conjecture that this zero temperature "critical point" could determine the properties of dense particle systems within a region of the parameter space to be determined, which in principle could include thermal and stressed systems. Fifteen years of intense theoretical and experimental work later, what have we learned about Jamming and glassy dynamics? In this paper, we discuss these issues in the light of the experiments we have been conducting with vibrated grains.

    2012-02-01

    We study jamming of low aspect-ratio cylindrical Delrin grains in a vertical channel. These cylindrical grains resemble antacid tablets, poker chips, or coins since their height is less than their diameter. Grains are allowed to fall through a vertical channel with a square cross section where the channel width is greater than the diameter of a grain and constant throughout the length of the channel with no obstructions or constrictions. Within this channel, grains are sometimes observed to form jams, stable structures supported by the channel walls with no support beneath them. The probability of jam occurrence and the strength or robustness of a jam is effected by the grain dimensions and channel size. We will present experimental measurements of the jamming probability and jam strength in this system and discuss the relationship of these results to other experiments and theories.

    Monitoring snow cover in alpine areas is important for the estimation of the water storage during the snowmelt season, especially in view of irrigation, hydropower production and water supply. Cost-efficiency and fine temporal resolution of images from the satellite-borne NOAA-AVHRR sensor indicate this source of information as a suitable candidate for monitoring snow cover extent. This information can also be used for validation of distributed snowmelt models. As a result of a long-term study, ten years of snow covered area depletion curves have been estimated using remote sensing in seven watersheds of size larger than 400 km2 in the Southern Alps.Coupling of satellite imagery with detailed topographic data and some ground measurements of snowpack depth and density provides regional estimates of snow water equivalent in northern Italy, upstream of Lakes Maggiore, Como, Iseo, Idro, and Garda. The basin water equivalent estimates are compared with the values obtained from the hydrological water balance equation used in two of the selected watersheds and computed for different snowmelt seasons.

  12. Prehospital trauma care reduces mortality. Ten-year results from a time-cohort and trauma audit study in Iraq

    PubMed Central

    2012-01-01

    Background Blunt implementation of Western trauma system models is not feasible in low-resource communities with long prehospital transit times. The aims of the study were to evaluate to which extent a low-cost prehospital trauma system reduces trauma deaths where prehospital transit times are long, and to identify specific life support interventions that contributed to survival. Methods In the study period from 1997 to 2006, 2,788 patients injured by land mines, war, and traffic accidents were managed by a chain-of-survival trauma system where non-graduate paramedics were the key care providers. The study was conducted with a time-period cohort design. Results 37% of the study patients had serious injuries with Injury Severity Score ≥ 9. The mean prehospital transport time was 2.5 hours (95% CI 1.9 - 3.2). During the ten-year study period trauma mortality was reduced from 17% (95% CI 15 -19) to 4% (95% CI 3.5 - 5), survival especially improving in major trauma victims. In most patients with airway problems, in chest injured, and in patients with external hemorrhage, simple life support measures were sufficient to improve physiological severity indicators. Conclusion In case of long prehospital transit times simple life support measures by paramedics and lay first responders reduce trauma mortality in major injuries. Delegating life-saving skills to paramedics and lay people is a key factor for efficient prehospital trauma systems in low-resource communities. PMID:22304808

    Intracranial hemorrhage (ICH) is a rare but major cause of death in immune thrombocytopenic purpura (ITP). The authors reviewed data of 1,840 patient with ITP, from 5 pediatric hematology centers in Egypt from 1997 to 2007, to study the incidence and risk factors of ICH. Ten cases of ICH were identified with a median age at presentation of 7.5 years; 4 patients had acute ITP, 2 persistent and 4 chronic. The platelet count was <10 x 10(9)/l in 7 cases, and only 1 patient had a history of head trauma. Seven children were on treatment prior to or at the time of occurrence of ICH and all were treated by pharmacotherapy. Two children died shortly afterwards due to late referral to a specialized center. Our results suggest that treatment does not prevent ICH and that it can occur at any time during the course of the disease. Delayed referral can be considered a risk factor for unfavorable outcome of ICH, highlighting the importance of teaching sessions for patients and their parents to minimize subsequent morbidity and mortality of ICH in children with ITP.

    SUMMARY CONFLICT OF INTEREST: none declared. Introduction Staphylococcal bacteremia/sepsis is one of the most serious bacterial infections around the world. In individuals with pre-existing diseases, there is always an increased risk of infections occurring due to impaired immune system, a variety of drug therapy, exposure to a diagnostic and therapeutic procedure and frequent hospitalizations. Objectives To analyze the prevalence of comorbidity in a patient with the staphylococcal bacteremia/sepsis according to the diagnosis, the site of infection and according to the isolated agent. Patients and methods We analyzed the patients affected by the staphylococcal bacteremia/sepsis and treated in the Clinic for Infectious Diseases during a ten-year period. Results 87 patients were included, out of whom 20 (23%) with clinical signs of the bacteremia and 67 (77%) of sepsis. In the analyzed sample, in 36 (41.4%) were not registered comorbidity. Hospital infections are represented by the previous antibiotic, corticosteroid and chemo therapy, pressure ulcers, and different implants. In all comorbidity, the most common isolated bacteria was S. aureus primarily strain MSSA followed by MRSA strain which is more frequent in patients who were surgically treated (comorbidity–various implants). Conclusion The results suggest the importance of being mindful of the staphylococcal etiology of the bacteremia/sepsis in patients with comorbidities due to the selection of an adequate initial empirical therapy and reducing the risks of the septic shock.

    Closing the gap between evidence-based clinical practice standards and their inclusion in routine practice continues to be a major goal of health policy reforms. This gap is especially large for the care of children with psychiatric disorders-especially those from low-income families, many of whom are insured through Medicaid. To address this gap, we analyzed trends over ten years (2001-10) from Medicaid claims data describing changes over time in medication, psychotherapy, and combined treatment services for children diagnosed with attention deficit hyperactivity disorder (ADHD). Over this time, more children received treatments that conformed to practice standards, including the use of combination treatments of medication and psychotherapy. Rates of combined treatment increased by 74 percent, rates of psychotherapy alone more than doubled, and rates of medication alone decreased by 18 percent. Rates of diagnoses without any reimbursed treatment decreased by 39 percent. These trends suggest increasing adherence to clinical practice standards by providers serving children with ADHD in the Medicaid population, although the quality of those services is unknown.

ACV resistance has traditionally been a major concern for immunocompromised patients with a frequency reported between 2.5% and 10%. The aim of this study was to reassess the status of HSV resistance to ACV in immunocompetent and immunocompromised patients over a ten year period, between 2002 and 2011. This was done by retrospectively following 1425 patients. In immunocompetent patients, prevalence of resistance did not exceed 0.5% during the study period; whereas in immunocompromised patients, a significant increase was observed, rising from 3.8% between 2002 and 2006 (7/182 patients) to 15.7% between 2007 and 2011 (28/178) (p=0.0001). This sharp rise in resistance may largely be represented by allogeneic hematopoietic stem cell transplant patients, in which the prevalence of ACV resistance rose similarly from 14.3% (4/28) between 2002 and 2006 to 46.5% (26/56) between 2007 and 2011 (p=0.005). No increase in ACV resistance was detected in association with other types of immune deficiencies. Genotypic characterization of HSV UL23 thymidine kinase and UL30 DNA polymerase genes revealed 11 and 7 previously unreported substitutions, respectively. These substitutions may be related to potential polymorphisms, drug resistance, or other mutations of unclear significance.

    Background Hemoptysis, secondary to aortobronchial fistula, is a rare and potentially fatal condition. We present a case report of noninvasive endovascular treatment of hemoptysis due to aortobronchial fistula, in a patient with a history of thoracic aorta traumatic rupture. Patients and methods A 55-year-old man presented with massive hemoptysis and a 2-month history of recurrent hemoptysis. Ten years previously, the patient had undergone thoracic aortic interposition of Dacron graft as a surgical repair of thoracic aorta traumatic rupture. Despite the severity of bleeding, the patient was haemodynamically stable. Spiral computed tomography angiography of the thorax revealed a saccular pseudoaneurysm of thoracic aorta of about 4.2 cm in diameter at the level of the previous aortic repair. The computed tomography examination also revealed alveolar infiltrations and a ground-glass appearance in the adjacent left upper lobe, indicative of extravasation to the lung parenchyma. Results Under the impression of aortobronchial fistula, a digital angiography was immediately performed. It confirmed the diagnosis and an endovascular tubular graft Gore TAG was interposed via femoral approach. The bleeding ceased gradually and the patient was discharged free of symptoms. At the 1-month and 2-month follow up, the CT revealed an improvement of the infiltrations and a decrease of the pseudoaneurysm size. Conclusions Aortobronchial fistula should be included in the differential diagnosis in patients with hemoptysis and even a long history of thoracic aorta traumatic rupture. Endovascular stenting seems to represent a safe, non invasive therapeutical option. Early diagnosis, prompt management and long term follow up maybe proved lifesaving.

    The Euro-Mediterranean Seismological Center (EMSC) is in charge of collecting seismological parametric data recorded by the local networks of the Euro-Mediterranean region in order to improve data availability for the seismologists and to rapidly produce a comprehensive seismicity bulletin for the region. The aims are to reproduce the seismicity as imaged by the local agencies when events occur within their network and to improve event location in borders regions and off-shore. In this presentation, we show ten years of seismicity that occurred in the Euro-Mediterranean region. Event locations have been obtained in the Euro-Med Bulletin for the period January 1998 to December 2007 by merging parametric data collected from 77 seismological agencies. Thanks to the many contributions, the Euro-Med Bulletin displays a high coverage of the region with the collection of data recorded by 2,625 stations and only two known missing networks. In total, more than 100,000 events are included for the period 1998-2007. We present here the performances of the Euro-Med Bulletin and their evolution over the years. In the spring 2009, the EMSC will produce a specific map of the Euro-Med seismicity. This map, dedicated to a wide audience will require a careful review and didactic selection of data. A special effort is needed to further discard non tectonic events from the current Euro-Med bulletin. This can be achieved by setting up additional collection of event type information (from rockburst to mine activity) with the help of the local networks. Additionally, the currently available bulletin may be recomputed using the global velocity model AK135.

    As of February 2014, the Canadian-led Atmospheric Chemistry Experiment (ACE) satellite mission has been making measurements of the Earth's atmosphere for ten years. As ACE operations have extended beyond the initial two-year mission, there is a continuing need to validate the trace gas data products from the ACE-Fourier Transform Spectrometer (ACE-FTS) and the Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (ACE-MAESTRO) instruments. Ground-based measurements provide critical data for the validation of satellite retrievals of trace gases and for the assessment of long-term stability of these measurements. In particular, validation comparisons are needed for ACE during Arctic springtime to understand better the measurements of species involved in stratospheric ozone chemistry. To this end, eleven Canadian Arctic Atmospheric Chemistry Experiment (ACE) Validation Campaigns have been conducted during the spring period (February - April in 2004 - 2014) at the Polar Environment Atmospheric Research Laboratory (PEARL) in Eureka, Nunavut (80°N, 86°W). This period coincides with the most chemically active time of year in the Arctic, as well as a significant number of satellite overpasses. A suite of as many as 12 ground-based instruments, as well as frequent balloon-borne ozonesonde and radiosonde launches, have been used in each campaign. These instruments include: a ground-based version of the ACE-FTS (PARIS - Portable Atmospheric Research Interferometric Spectrometer), a terrestrial version of the ACE-MAESTRO, a SunPhotoSpectrometer, two zenith-viewing UV-visible grating spectrometers, a Bomem DA8 Fourier transform spectrometer, a Bruker 125HR Fourier transform spectrometer, a Systeme d'Analyse par Observations Zenithales (SAOZ) instrument, and several Brewer spectrophotometers. In the past several years, these results have been used to validate the measurements by the ACE-FTS and ACE-MAESTRO instruments on SCISAT as well

    Introduction. The main indication for knee arthrodesis in tumor surgery is a tumor that requires an extensive resection in which the joint surface cannot be preserved. We report a patient that had knee desarthrodesis 41 years after giant cell tumor resection followed by a knee arthrodesis. This is the longest reported follow-up after desarthrodesis and conversion to total knee arthroplasty (TKA), almost ten years. Case Report. A 71-year-old man with a distal femoral giant cell tumor had undergone a resection of the distal femur and knee arthrodesis using Kuntscher nail in 1962. In July 2003 he experienced gradually increasing pain of his left knee. We performed a desarthrodesis and conversion to TKA in 2005. The postoperative period passed uneventfully as his pain and gait improved, with gradually increasing range of motion (ROM) and no infection. He now walks independently, with no brace or contractures. Conclusion. Desarthrodesis of the knee joint and conversion to TKA are a difficult surgical choice with a high complication risk. However, our patient's life style has improved, he has no pain, and he can ascend and descend stairs more easily. The surgeon has to be very meticulous in selecting a patient for knee arthrodesis and counseling them to realize that their expectations may not be achievable. PMID:26688766

  1. Jamming versus caging in three dimensional jamming percolation

    We investigate a three-dimensional kinetically-constrained model that exhibits two types of phase transitions at different densities. At the jamming density $ \\rho_J $ there is a mixed-order phase transition in which a finite fraction of the particles become frozen, but the other particles may still diffuse throughout the system. At the caging density $ \\rho_C > \\rho_J $, the mobile particles are trapped in finite cages and no longer diffuse. The caging transition occurs due to a percolation transition of the unfrozen sites, and we numerically find that it is a continuous transition with the same critical exponents as random percolation.

    The Hokkaido Study on Environment and Children's Health is an ongoing cohort study that began in 2002. The study consists of two prospective birth cohorts, the Sapporo cohort (n = 514) and the Hokkaido large-scale cohort (n = 20,940). The primary goals of this study are to first examine the potential negative effects of perinatal environmental chemical exposures on birth outcomes, including congenital malformations and growth retardation; second, to evaluate the development of allergies, infectious diseases and neurodevelopmental disorders and perform longitudinal observations of the children's physical development to clarify the causal relationship between these outcomes and environmental chemicals; third, to identify individuals genetically susceptible to environmental chemicals; finally, to identify the additive effects of various environmental factors in our daily life, such as secondhand smoke exposure or low folate intake during early pregnancy. In this paper, we introduce our recent progress in the Hokkaido study with a cohort profile updated in 2013. For the last ten years, we followed pregnant women and their offspring, measuring various environmental chemicals, i.e., PCB, OH-PCB and dioxins, PFCs (Perfluorinated Compounds), Organochlorine pesticides, Phthalates, bisphenol A and mercury. We discovered that the concentration of toxic equivalents (TEQ) of dioxin and other specific congeners of PCDF or PCDD have effects on birth weight, infants' neurodevelopment and immune function. There were significant gender differences in these effects; our results suggest that male infants have more susceptibility to those chemical exposures than female infants. Interestingly, we found maternal genetic polymorphisms in AHR, CYP1A1 or GSTs that significantly modified the dioxin concentrations in maternal blood, suggesting different dioxin accumulations in the bodies of individuals with these genotypes, which would lead to different dioxin exposure levels. These genetic

    Aerosol-cloud interaction continues to be one of the leading uncertain components of climate models, primarily due to the lack of an adequate knowledge of the complex microphysical and radiative processes associated with the aerosolcloud system. The situations when aerosols and clouds are found in the same atmospheric column, for instance, when light-absorbing aerosols such as biomass burning generated carbonaceous particles or wind-blown dust overlay low-level cloud decks, are commonly found over several regional of the world. Contrary to the cloud-free scenario over dark surface, for which aerosols are known to produce a net cooling effect (negative radiative forcing) on climate, the overlapping situation of absorbing aerosols over cloud can potentially exert a significant level of atmospheric absorption and produces a positive radiative forcing at top-of-atmosphere. The magnitude of direct radiative effects of aerosols above cloud depends directly on the aerosol loading, microphysical-optical properties of the aerosol layer and the underlying cloud deck, and geometric cloud fraction. We help in addressing this problem by introducing a novel product of optical depth of absorbing aerosols above clouds retrieved from near-UV observations made by the Ozone Monitoring Instrument (OMI) on board NASA's Aura platform. The presence of absorbing aerosols above cloud reduces the upwelling radiation reflected by cloud and produces a strong `color ratio' effect in the near-UV region, which can be unambiguously detected in the OMI measurements. Physically based on this effect, the OMACA algorithm retrieves the optical depths of aerosols and clouds simultaneously under a prescribed state of atmosphere. The algorithm architecture and results from a ten-year global record including global climatology of frequency of occurrence and above-cloud aerosol optical depth, and a discussion on related future field campaigns are presented.

    Lead exposure in waterfowl was studied using noninvasive fecal sampling in the Guadalquivir Marshes in Spain, an area affected by the 1998 Aznalcóllar mine disaster. Feces of greylag geese (Anser anser, n = 191) and purple gallinule (Porphyrio porphyrio, n = 91) were collected from three different impacted sites (Entremuros, Caracoles and Cerro de los Ánsares) during the winters of 2004 to 2008. Lead and aluminium (an indicator of sediment ingestion) and Pb isotope signatures (to discriminate between sources of Pb exposure) were analyzed in freeze-dried, acid digested samples. The concentrations of fecal porphyrins and biliverdin were determined as noninvasive biomarkers to study Pb exposure effects. Results showed a decrease in Pb exposure over time in wintering greylag geese. In contrast, for purple gallinule resident in the Entremuros a clear trend was not evident. For both species, sediment ingestion appeared to be the main source of exposure to Pb. In the Entremuros, some samples from purple gallinule were detected with higher Pb levels than expected for simple soil ingestion, and these had Pb isotopic profiles compatible with mining sludge or Pb shot. Whilst fecal Pb isotopic profiles were effective in differentiating between samples from sites with different levels and sources of pollution, the combined use of element ratios (such as Pb/Al) and other non-traditional stable isotope signatures may also prove worthwhile. Overall, the fecal Pb levels detected were below those described in feces for waterfowl from other uncontaminated areas(<10 µg/g d.w.). Despite this, for both species fecal Pb levels were positively correlated with porphyrin excretion, and for purple gallinule, with the coproporphyrin III/I ratio, suggesting some subtle effects on heme synthesis in birds. Ten years after the mine spill, Pb contamination in birds by this pollution source was still detectable and subtlethal effects may persist. PMID:23437364

    The effect of different densities of varnishleaf ceanothus (Ceanothus velutinus var. laevigatus) and herbaceous vegetation control on stem diameter, height, and volume of plantation Douglas-fir (Pseudotsuga menziesii var. menziesii) seedlings was examined during the 10 yr following planting. Initial densities of ceanothus ranged between 0 and 15,000 seedlings/ha and were obtained by interplanting ceanothus germinants or chemical thinning after clearcutting and broadcast-burning. Herbaceous vegetation control was achieved by a single application of glyphosate following planting, with shrub seedlings covered. Ceanothus density in the range of 0 to 6,750 plants/ha did not have an effect on Douglas-fir diameter, height, or volume at age 10; however, Douglas-fir growth was significantly decreased when ceanothus densities reached 15,000 plants/ha. Ten years after planting, Douglas-fir volume in the treatments with 6,750 ceanothus/ha or less was 1.7 times greater than that in the 15,000 ceanothus/ha treatment. On the other hand, removal of herbaceous vegetation after planting significantly increased tree diameter, height, and volume, regardless of ceanothus density. Even 10 yr after the application of the treatment, trees without early herb competition grew faster and had mean dbh, height, and volume that were 1.02 cm, 0.55 m, and 12.98 dm3/tree greater respectively than those with herbs. Thus, a treatment at plantation establishment to control herbaceous vegetation and to reduce ceanothus density to less than 7,000 plants/ha will ensure an increase in growth and stocking for at least 10 yr.

  6. Ten years of health workforce planning in the Netherlands: a tentative evaluation of GP planning as an example

    2012-01-01

    Introduction In many countries, health-care labour markets are constantly being challenged by an alternation of shortage and oversupply. Avoiding these cyclic variations is a major challenge. In the Netherlands, a workforce planning model has been used in health care for ten years. Case description Since 1970, the Dutch government has explored different approaches to determine the inflow in medical schools. In 2000, a simulation model for health workforce planning was developed to estimate the required and available capacity of health professionals in the Netherlands. In this paper, this model is explained, using the Dutch general practitioners as an example. After the different steps in the model are clarified, it is shown how elements can be added to arrive at different versions of the model, or ‘scenarios’. A comparison is made of the results of different scenarios for different years. In addition, the subsequent stakeholder decision-making process is considered. Discussion and evaluation Discussion of this paper shows that workforce planning in the Netherlands is a complex modelling task, which is sensitive to different developments influencing the balance between supply and demand. It seems plausible that workforce planning has resulted in a balance between supply and demand of general practitioners. Still, it remains important that the modelling process is accepted by the different stakeholders. Besides calculating the balance between supply and demand, there needs to be an agreement between the stakeholders to implement the advised training inflow. The Dutch simulation model was evaluated using six criteria to be met by models suitable for policy objectives. This model meets these criteria, as it is a comprehensive and parsimonious model that can include all relevant factors. Conclusion Over the last decade, health workforce planning in the Netherlands has become an accepted instrument for calculating the required supply of health professionals on a

    In a longitudinal cohort (prevention group, n=213, comparison group, n=163) of 10-year prospective follow-up we addressed efficacy of 5-year-long multifactor preventive intervention, conducted in a sample of population of 12 year old boys. Preventive intervention was carried out both at populational level and among persons with risk factors of development of cardiovascular diseases with the use of group, individual, and partly family approaches, and was directed at rationalization of nutrition, elevation of physical activity and prevention of harmful habits. During first 3 years of prevention we succeeded to achieve stable statistically significant lowering of mean levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, and atherogeneity index, as well as to affect fatty component of body mass (skinfold thickness). Long term effect of 5-year long preventive intervention manifested as significantly lower level of systolic blood pressure, lower prevalence of low levels of high density lipoprotein cholesterol, smaller increment of low density lipoprotein cholesterol and index of atherogeneity in the prevention group. These results evidence that prevention of main factors of risk of development of cardiovascular diseases (obesity, arterial hypertension, disorders of lipid composition of the blood, and low physical activity) in child and adolescent age in the period of active growth and development is feasible, effective, safe and is able to lead to decrease of levels of these factors in adults, but should last uninterruptedly until formation of stable habits of healthy life style.

    There are deep, but hidden, geometric structures within jammed systems, associated with hidden symmetries. These can be revealed by repeated transformations under which these structures lead to fixed points. These geometric structures can be found in the Voronoi tesselation of space defined by the packing. In this paper we examine two iterative processes: maximum inscribed sphere (MIS) inversion and a real-space coarsening scheme. Under repeated iterations of the MIS inversion process we find invariant systems in which every particle is equal to the maximum inscribed sphere within its Voronoi cell. Using a real-space coarsening scheme we reveal behavior in geometric order parameters which is length-scale invariant.

  9. Similarities between protein folding and granular jamming

    2012-01-01

    Grains and glasses, widely different materials, arrest their motions upon decreasing temperature and external load, respectively, in common ways, leading to a universal jamming phase diagram conjecture. However, unified theories are lacking, mainly because of the disparate nature of the particle interactions. Here we demonstrate that folded proteins exhibit signatures common to both glassiness and jamming by using temperature- and force-unfolding molecular dynamics simulations. Upon folding, proteins develop a peak in the interatomic force distributions that falls on a universal curve with experimentally measured forces on jammed grains and droplets. Dynamical signatures are found as a dramatic slowdown of stress relaxation upon folding. Together with granular similarities, folding is tied not just to the jamming transition, but a more nuanced picture of anisotropy, preparation protocol and internal interactions emerges. Results have implications for designing stable polymers and can open avenues to link protein folding to jamming theory. PMID:23093180

    "What do you want to be in ten years?' This is a question we ask our students, freshmen and transfer, when they first arrive in the College student services center. Often the answer is "I don't know. I just want to be in meteorology." This response leads to a discussion of career opportunities in meteorology and related fields, including what might be called faux-careers, such as professional storm chasing and weather tour operations. (Students often have been misled by what they have seen in television shows.) Many students arrive on our doorstep with their heart set on a degree in meteorology, but lack knowledge of what the field is about or how challenging a meteorology degree program really is. We find ourselves spending a great deal of time convincing students that they need to explore the real opportunities in meteorology and related fields, which are many. Fortunately, because of the concentration of University and federal weather organizations in the National Weather Center and private sector weather companies in adjacent buildings, we are able to show concrete examples of real careers by means of tours, job shadowing, and introductions to alumni employed in these organizations. Also, as the students' progress in their studies, they discover the many opportunities for undergraduate employment, research experiences, and internships in these same organizations, through which they gain an appreciation for what constitutes a real career in modern meteorology. Further, many of today's careers in meteorology require a broad, global perspective. Unfortunately, many meteorology students have not traveled widely, but again have only seen what the media provides about distant lands and peoples. Accordingly, we encourage our undergraduate students to take advantage of our unique opportunities for overseas experiences in meteorology.

    Granular materials are collections of discrete, macroscopic particles characterized by relatively straightforward interactions. Despite their apparent simplicity, these systems exhibit a number of intriguing phenomena, including the jamming transition, in which a disordered collection of grains becomes rigid when its density exceeds a critical value. Many aspects of this transition have been explored, but an explanation of the underlying dynamical mechanisms for the transition remains elusive. Here, applying nonlinear dynamical techniques to simulated two-dimensional Couette shear cells, we reveal the mechanisms of jamming and find that they conflict with the prevailing picture of growing cooperative regions. In addition, at the density corresponding to random close packing, we find a dynamical transition from chaotic to non-chaotic states accompanied by diverging dynamical length- and timescales. Furthermore, we find that the dominant cooperative dynamical modes are strongly correlated with particle rearrangements and become increasingly unstable before stress jumps, providing a way to predict the times and locations of these striking stress-release events in our simulations.

  18. Effect of friction on shear jamming

    Wang, Dong; Bares, Jonathan; Dijksman, Joshua; Ren, Jie; Zheng, Hu; Behringer, Robert

    Shear jamming of granular materials was first found for systems of frictional disks, with a static friction coefficient μ ~ 0 . 6 (Bi et al. Nature (2011)). Jamming by shear is obtained by starting from a zero-stress state with a packing fraction ϕ between ϕJ (isotropic jamming) and a lowest ϕS for shear jamming. This phenomenon is associated with strong anisotropy in stress and the contact network in the form of force chains, which are stabilized and/or enhanced by the presence of friction. Whether shear jamming occurs for frictionless particles is under debate. The issue we address experimentally is how changing friction affects shear jamming. By applying a homogeneous simple shear, we study the effect of friction by using photoelastic disks either wrapped with Teflon to reduce friction or with fine teeth on the edge to increase friction. Shear jamming is still observed; however, the difference ϕJ -ϕS is smaller with lower friction. We also observe larger fluctuations due to initial configurations both at the lowest and the highest friction systems studied. Ongoing work is to use particles made of gelatin to reduce the friction coefficient to the order of 0.01. We acknowledge support from NSF Grant DMR1206351, NASA Grant NNX15AD38G and the William M.

By applying a homogeneous simple shear, we study the effect of friction by using photoelastic disks either wrapped with Teflon to reduce friction or with fine teeth on the edge to increase friction. Shear jamming is still observed; however, the difference ϕJ -ϕS is smaller with lower friction. We also observe larger fluctuations due to initial configurations both at the lowest and the highest friction systems studied. Ongoing work is to characterize response from different friction systems under shear with information at local scale. We acknowledge support from NSF-DMR1206351, NASA NNX15AD38G and W.M.

    Granular matter at the jamming transition is poised on the brink of mechanical stability, and hence it is possible that these random systems have topologically protected surface phonons. Studying two model systems for jammed matter, we find states that exhibit distinct mechanical topological classes, protected surface modes, and ubiquitous Weyl points. The detailed statistics of the boundary modes shed surprising light on the properties of the jamming critical point and help inform a common theoretical description of the detailed features of the transition.

    Lidar (Light Detection and Range) is a brand-new field and research hotspot. Ranging lidar is studied in this paper. Specifically, its basic working principle and photoelectric jamming mechanism are introduced. Then, the ranging error jamming success rate rule is developed for laser distance deception jamming. And the effectiveness evaluation of laser blinding jamming is based on the influence level on ranging accuracy and ranging function. The results have some reference value to evaluation of jamming test effectiveness.

    2016-09-01

    We describe a protocol by which an imaging system could be protected against jamming by a malevolent party. Our protocol not only allows recognition of the jamming, but also allows for the recovery of the true image from the jammed one. We apply the method to jamming of quantum ghost imaging, for which the jamming detection probability is increased when the imaging light is entangled. The method can also be used to provide image recovery in general noisy environments.

  3. Ice Jams the Ob River

    NASA Technical Reports Server (NTRS)

    2007-01-01

    Russia's Ob River flows from south to north, and each summer, it thaws in the same direction. The result is that an ice jam sits downstream from thawed portions of the river, which is laden with heavy runoff from melted snow. On June 29, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS) flying on NASA's Terra satellite captured this image of the almost completely thawed Ob River. The scene is typical for early summer. South of the ice jam, the Gulf of Ob is swollen with pent-up run-off, and upstream from that, the river is widened as well. Unable to carve through frozen land, the river has little choice but to overflow its banks. For a comparison of early summer and autumn conditions, see Flooding on the Ob River in the Earth Observatory's Natural Hazards section. Besides the annual overflow, this image captures other circumstances of early summer. Sea ice is retreating from the Kara Sea. A lingering line of snow cover snakes its way along the Ob River, to the west. And while the land is lush and green in the south, it appears barren and brown in the north. Near the mouth of the river and the Kara Sea, the land is cold-adapted tundra, with diminutive plants and a short growing season. Just as the ice plugging the river had yet to thaw in the Far North's short summer, the tundra had not yet to greened up either. In this image it still appears lifeless beige.

  4. Scaling theory of the jamming transition

    NASA Astrophysics Data System (ADS)

    Liu, Andrea; Goodrich, Carl; Sethna, James; Nagel, Sidney

    The concept of jamming was first introduced at the University of Chicago by Sid Nagel and Tom Witten. By now we know that there is a zero-temperature critical jamming transition that marks the onset of rigidity in packings of soft repulsive spheres. In contrast to the perfect fcc crystal state, which is the maximally stable state for such systems, the jammed state is only marginally stable mechanically, and thus represents an opposite extreme to the perfect crystal. This marginal stability gives rise to power law scalings and diverging length scales at the transition. Here I will discuss recent developments that put the jamming transition in the same place that the Ising transition was when Leo Kadanoff introduced the ideas of coarse-graining and rescaling into critical phenomena.

  5. Nonlinear and nonlocal rheology of jammed matter

    NASA Astrophysics Data System (ADS)

    Tighe, Brian

    Emulsions, foams, and grains all jam into a weakly elastic state when confined by pressure. By now the mechanics of jammed matter is well understood in the case of slow, weak, and homogeneous forcing - but in reality, it is rare for all three of these assumptions to hold. Here we demonstrate the complex rheology that results when jammed materials are forced at finite rate, finite amplitude, and finite wavelength. Using computer simulations, we subject dense soft sphere packings to a host of rheological tests, including stress relaxation, flow start-up, oscillatory shear, and standing wave forcing. These allow us to tease apart the influence of viscous, nonlinear, and nonlocal effects, and also to probe the link between particle dynamics and bulk response. We identify strain, time, and length scales that depend critically on the distance to the jamming transition, and which govern the onset of shear thinning, strain softening, and gradient elasticity.

    The jamming transition of particles with finite-range interactions is characterized by a variety of critical phenomena, including power-law distributions of marginal contacts. We numerically study a recently proposed simple model of jamming, which is conjectured to lie in the same universality class as the jamming of spheres in all dimensions. We extract numerical estimates of the critical exponents, θ=0.451±0.006 and γ=0.404±0.004, that match the exponents observed in sphere packing systems. We analyze finite-size scaling effects that manifest in a subcritical cutoff regime and size-independent but protocol-dependent scaling curves. Our results support the conjectured link with sphere jamming, provide more precise measurements of the critical exponents than previously reported, and shed light on the finite-size scaling behavior of continuous constraint satisfiability transitions.

    Between 1972 and 1977, a prospective study was conducted at the University of Florida on the role of total body irradiation (TBI) in the management of stage II-IV non-Hodgkin's lymphoma (NHL). Forty-four consecutive de novo (DN) patients (including ten stage II, 18 stage III, and 16 stage IV), as well as 16 previously treated (PT) patients, were accrued. Twenty of the 44 DN patients were symptomatic at presentation. Complete clinical responses were obtained in 20 of the 27 DN patients with favorable histologies (FH), and six of the 17 with unfavorable histologies (UH). Partial responses were obtained in six patients with FH and 11 patients with UH; only one patient showed no response to TBI. By univariate analysis, PT patients showed a trend for decreased relapse-free survival (P = .066) and decreased survival (P = .093). Multivariate analysis identified the best predictors of response rate to be histology (P = .0146) and marrow involvement (P = .0854); of relapse-free survival, histology (P = .0035), and TBI dose (P = .002); and of absolute survival, age (P = .0012), histology (P = .012), and TBI dose (P = .029). Thirty of the 41 patients who relapsed underwent salvage treatment with either chemotherapy or radiation. Twenty-three of the 30 undergoing salvage therapy obtained a second complete clinical response. There were no treatment-related deaths. The most common complication was thrombocytopenia. The major late complications were myeloproliferative disorders in four patients, which occurred only after cumulative TBI doses in excess of 200 cGy.

    Fifty-five former opioid addicts who have been methadone maintained patients for 10 or more years and whose urine has tested negative for drugs for 2 or more years were compared to 99 former opioid addicts who have been medication-free for 10 or more years. Groups were comparable in age and education, but the medication-free subjects were younger when having started opioids with more severe addiction scores. Methadone maintained patients presented with a higher proportion of psychiatric comorbidity and chronic pain. Their scores of perceived sleep quality and cognitive state were poorer than the medication-free individuals. Possible explanations of the differences are discussed in this article.

    2015-08-21

    Using random walk simulations we explore diffusive transport through monodisperse sphere packings over a range of packing fractions ϕ in the vicinity of the jamming transition at ϕ(c). Various diffusion properties are computed over several orders of magnitude in both time and packing pressure. Two well-separated regimes of normal "Fickian" diffusion, where the mean squared displacement is linear in time, are observed. The first corresponds to diffusion inside individual spheres, while the latter is the long-time bulk diffusion. The intermediate anomalous diffusion regime and the long-time value of the diffusion coefficient are both shown to be controlled by particle contacts, which in turn depend on proximity to ϕ(c). The time required to recover normal diffusion t* scales as (ϕ-ϕ(c))(-0.5) and the long-time diffusivity D(∞)∼(ϕ-ϕ(c))0.5, or D(∞)∼1/t*. It is shown that the distribution of mean first passage times associated with the escape of random walkers between neighboring particles controls both t* and D(∞) in the limit ϕ→ϕ(c).

  12. Jamming in Vibrated Granular Systems

    NASA Astrophysics Data System (ADS)

    Utter, Brian

    2009-03-01

    Granular materials exist all around us, from avalanches in nature to the mixing of pharmaceuticals, yet the behavior of these``fluids'' is poorly understood. Their flow can be characterized by the continuous forming and breaking of a strong force network resisting flow. This jamming/unjamming behavior is typical of a variety of systems, including granular flows, and is influenced by factors such as grain packing fraction, applied shear stress, and the random kinetic energy of the particles. I'll present experiments on quasi-static shear and free-surface granular flows under the influence of external vibrations. By using photoelastic grains, we are able to measure both particle trajectories and the local force network in these 2D flows. We find through particle tracking that dense granular flow is composed of comparable contributions from the mean flow, affine, and non-affine deformations. During shear, sufficient external vibration weakens the strong force network and reduces the amount of flow driven by sidewalls. In a rotating drum geometry, large vibrations induce failure as might be expected, while small vibration leads to strengthening of the pile. The avalanching behavior is also strongly history dependent, as evident when the rotating drum is driven in an oscillatory motion, and we find that sufficient vibration erases the memory of the pile. These results point to the central role of the mobilization of friction in quasi-static granular flow.

    Long-term epidemiological and laboratory studies were carried out in a kindred with familial pheochromocytoma associated with von Hippel-Lindau disease. Thirteen members were affected by the syndrome and the trait appears to be transmitted in an autosomal dominant fashion. Of 13 patients, 7 had pheochromocytoma alone. Of the remaining six patients, one had pheochromocytoma combined with von Hippel-Lindau disease, four had pheochromocytoma with retinal disease only, and a single patient had a retinal lesion without pheochromocytoma. In four patients, pheochromocytoma antedated the development of retinal lesions. Ten members also had mild hypercalcemia without accompanying elevations of PTH in the 4 patients in whom this was determined. In all, hypercalcemia was corrected with removal of tumors, and no patient had a return of hypercalcemia in the absence of recurrent increases in urinary catecholamines. The clinical presentations in 12 patients varied markedly, as did their urinary excretion rates of norepinephrine, epinephrine and their metabolites. However, an analysis of the data revealed significant correlations not previously described between the urinary excretion of free catecholamines (norepinephrine plus epinephrine), blood pressure, the free catecholamine content of the tumor and the age of the patient. Urinary excretion of free norepinephrine plus epinephrine appear to be decreased with advancing age (p less than 0.001). Both systolic and diastolic blood pressures and the age of the patient were inversely correlated (p less than 0.01). A significant inverse relationship between the tumor content of free catecholamines and the age of the patients was, although to a lesser degree, also present (p less than 0.05). As a whole, the size of the tumors and their norepinephrine content were not correlated. We present a concept that, in familial pheochromocytoma, the metabolism of catecholamines is altered by the process of aging, and that this change modifies the

    Abstract The etiology of congenital scoliosis and its development remains unclear and has not yet been fully identified, even there are theories that congenital scoliosis could be derived from the failure of formation or failure of segmentation, which are etiologically heterogeneous with genetic, epigenetic, and environmental factors contributing to their occurrence. We reported a case of long-term follow-up after posterior vertebral column resection (PVCR) in both identical twins with similar congenital kyphoscoliosis at thoracolumbar levels. Twin I had been noticed by his parents to have asymmetry of his back at age 5 years, but no treatment was given. Twin II was first noticed to have a spinal problem at 11 years of age by his parents. Overtime, spine of both twins became further deviated to the left with kyphosis and was referred to our hospital. Both monozygotic twins were treated by PVCR and satisfactory results were demonstrated at 10-year follow-up. This case is the first report on the surgical treatment with PVCR, almost simultaneously, in both identical twins who had similar congenital vertebral anomalies causing kyphoscoliosis. Both identical twins with congenital kyphoscoliosis had undergone surgical correction by PVCR, anterior support with a mesh cage and posterior fusion using pedicle screws at the age of 14 years and achieved a satisfactory correction and a stable spine without curve progression with 10-year follow-up.

    Rainfall was collected on the University of Central Florida (UCF) campus near Orlando since July 1977 and at the Kennedy Space Center (KSC), Florida since August 1977. Since November 1983, the KSC site has been affiliated with the National Atmospheric Deposition Network. Annual volume weighted pH was slightly above the 10 year mean of 4.58 during four of the past five years. Nitrate concentrations have risen somewhat during recent years while excess sulfate concentrations have remained below the 10 year mean during four of the past years. These observations hold for both the UCF and KSC data. The distribution of individual sample pH was nearly identical at UCF and KSC. Stepwise regression suggests that sulfate, nitrate, ammonium ion, and calcium play major roles in the description of rainwater acidity. Annual acid deposition and annual rainfall have varied from 30 to 50 meq/m2-yr and 100 to 180 cm/yr, respectively. Sea salt comprises about 25 percent (UCF) and greater than 50 percent (KSC) of total ionic composition.

    Background Silicone breast implants have long been used for breast augmentation and reconstruction. During this time, these medical devices have gone through a number of modifications to improve their safety, quality, and clinical outcome performance. Objectives The authors conducted a 10-year study to determine the safety and effectiveness of Natrelle 410 silicone breast implants. Methods This prospective, multicenter study enrolled 941 subjects who were undergoing either augmentation, augmentation revision, reconstruction, or reconstruction revision. Data on complications, reoperations, explantations, and subject satisfaction were collected at annual clinic visits, and one-third of subjects underwent biennial magnetic resonance imaging (MRI) to screen for implant rupture. The authors used the Kaplan-Meier estimator to calculate risk rates for local complications, reoperations, and explantations. Results Capsular contracture rates increased approximately 1% per year from the previously reported 6-year rates. The rates were significantly lower than those from the Natrelle round gel core study. The overall rate of confirmed ruptured implants in subjects who underwent MRI was 5.7%. Eleven late seromas were reported. The most common reason for explantation was a subject requesting a size or style change. Satisfaction rates remained high through 10 years, with most subjects saying they were somewhat or definitely satisfied with their implants. Conclusions This 10-year prospective trial demonstrated the long-term safety and effectiveness of Natrelle 410 anatomical form-stable implants. The complication rates were low and the satisfaction rates were high. Level of Evidence: 1 Therapeutic PMID:25717116

    2012-08-01

    In recent years, the development of advanced driver assistance systems (ADAS) - mainly based on lidar and cameras - has considerably improved the safety of driving in urban environments. These systems provide warning signals for the driver in the case that any unexpected traffic circumstance is detected. The next step is to develop systems capable not only of warning the driver but also of taking over control of the car to avoid a potential collision. In the present communication, a system capable of autonomously avoiding collisions in traffic jam situations is presented. First, a perception system was developed for urban situations—in which not only vehicles have to be considered, but also pedestrians and other non-motor-vehicles (NMV). It comprises a differential global positioning system (DGPS) and wireless communication for vehicle detection, and an ultrasound sensor for NMV detection. Then, the vehicle's actuators - brake and throttle pedals - were modified to permit autonomous control. Finally, a fuzzy logic controller was implemented capable of analyzing the information provided by the perception system and of sending control commands to the vehicle's actuators so as to avoid accidents. The feasibility of the integrated system was tested by mounting it in a commercial vehicle, with the results being encouraging.

    Bone remodeling after a hip arthroplasty has been quantified with dual energy x-ray absorptiometry, usually for short-term follow-up. We used this technique to determine the long-term remodeling produced by a hydroxyapatite-coated, anatomic stem. Eighty patients with unilateral hip osteoarthritis were included in the study. The contralateral, healthy hip was taken as control. Bilateral dual energy x-ray absorptiometry scans were done before the surgery, at 15 days, and 1 and 10 years postoperatively. There was a decrease of bone mineral density in zones 1 and 7, which ranged from 12.2% to 27.3% at the end of the first year. There were no changes in zones 1 to 6 from the 1st to the 10th year, but there was a late decrease, up to 42.9%, in zone 7. The changes of bone mineral density promoted by this stem occurred in the first postoperative year. Late loss was seen only in area 7.

    2015-05-01

    This policy brief presents 10-year trends in several key health and wellness indicators for children ages 0-5 in California. These indicators are health insurance coverage; source of medical care; dental visits; overweight-for-age; parents singing and reading to their child and going out with the child; and preschool attendance. The data are from the California Health Interview Survey (CHIS), the largest state health survey in the U.S. The survey gathers information on a range of health behaviors and health conditions, as well as on access to health care among children, adolescents, and adults in California. A number of these key indicators are compared by income and by racial/ethnic group. This policy brief covers the years 2003 to 2011-2012, a period in which public health efforts for children focused on childhood obesity and improved nutrition, access to low-cost and free dental services, and the expansion of children's health insurance programs. CHIS data show improvement in health insurance coverage and access to dental services for low-income children over the 10-year period. However, the percentage of children who were overweight for their age remained unchanged among those in households with incomes below 200 percent of the federal poverty level (FPL). In terms of measures associated with school readiness, preschool attendance dropped overall between 2003 and 2011-2012, but the proportions of parents who sang, read, and went out with their children every day increased significantly during the 10-year period.

    Investigating the recovery capacity of wildlife populations following demographic crashes is of great interest to ecologists and conservationists. Opportunities to study these aspects are rare due to the difficulty of monitoring populations both before and after a demographic crash. Ebola outbreaks in central Africa have killed up to 95% of the individuals in affected western lowland gorilla (Gorilla gorilla gorilla) populations. Assessing whether and how fast affected populations recover is essential for the conservation of this critically endangered taxon. The gorilla population visiting Lokoué forest clearing, Odzala-Kokoua National Park, Republic of the Congo, has been monitored before, two years after and six years after Ebola affected it in 2004. This allowed us to describe Ebola's short-term and long-term impacts on the structure of the population. The size of the population, which included around 380 gorillas before the Ebola outbreak, dropped to less than 40 individuals after the outbreak. It then remained stable for six years after the outbreak. However, the demographic structure of this small population has significantly changed. Although several solitary males have disappeared, the immigration of adult females, the formation of new breeding groups, and several birth events suggest that the population is showing potential to recover. During the outbreak, surviving adult and subadult females joined old solitary silverbacks. Those females were subsequently observed joining young silverbacks, forming new breeding groups where they later gave birth. Interestingly, some females were observed joining silverbacks that were unlikely to have sired their infant, but no infanticide was observed. The consequences of the Ebola outbreak on the population structure were different two years and six years after the outbreak. Therefore, our results could be used as demographic indicators to detect and date outbreaks that have happened in other, non-monitored gorilla

    2016-04-01

    We report on the chemical and Pb isotopic compositions of epiphytic lichens collected from small tree branches in the urban area of the city of Metz (NE France). Lichens were collected in five different years between 2001 and 2009. The data are first compared year to year in order to document any temporal changes and trends in metal atmospheric fallout. The area studied was then subdivided into different zones on the basis of land-use (urban, suburban, rural and industrial) in order to determine potential spatial gradients. The median concentrations and enrichment factors (EF, normalized to Al) of Pb and other metals (Cu, Zn, Cd, Ni, Cr, Hg, Fe) in lichens from the urban, suburban, and rural zones show no systematic variation between 2001 and 2008. However, the metal EFs show spatial variation and are generally highest in the urban area and lowest in the rural area. Lichens within the industrial zone (collected in 2009), which is dominated by steel industries, are richest in Al, Fe, Cr, Pb, and Zn. Although the Al concentration is high in these lichens, the EFs for the cited metals are several times higher than those measured in lichens from the other three zones. No significant differences were noted for Hg, Cd, Cu and or Ni. Lead isotopic compositions measured in lichens may be highly variable from year to year and from zone to zone. The variation is primarily interpreted to result from mixing between: (i) Pb added to gasoline (and recycled through re-emission of road dust in the atmosphere); (ii) regional industrial Pb from long-range transportation and/or mixed with urban Pb; and (iii) local industrial Pb. The median isotopic compositions of individual zones are distinct, suggesting variable mixing of these three sources. The annual variations show that 2001 was most affected by gasoline Pb, whereas 2003 and 2006 were more affected by the local steel industry.

    Severn Trent Water have been using constructed wetlands since 1991 as part of a flowsheet in which 6 DWF (Dry Weather Flow) is treated by rotating biological contactors (RBCs), and constructed reed beds used to provide both tertiary treatment and stormwater treatment. The company now has over 50 such sites using this flowsheet. Dimensioning and effluent quality achievable is reported and data presented showing the performance of reed beds treating stormwater alone or in admixture with RBC effluent. After 8-10 years of operation the condition of a number of storm reed beds was assessed to determine the remaining asset life. The majority seem likely to achieve at least another five years of operation before further review is needed.

    The concentration of atmospheric methane trapped in Antarctic ice, [CH4], shows large variations over the last 800,000 years that appear to track changes in temperature (δD) on orbital timescales. As methane is a potent greenhouse gas and influences the tropospheric oxidizing capacity, it straddles issues of chemistry and climate, and attempts to explain past changes in its budget test our understanding of the Earth system. Amongst the most striking natural features of this record are: the differences in [CH4] between glacial and interglacial periods, for instance rising from around 360 ppbv at the Last Glacial Maximum (LGM; 21,000 years ago) to about 700 ppbv in the pre-industrial era (PI; 200 years ago); and the rapid rises of 100-200 ppbv, from a baseline of 360-460 ppbv, in response to northern-hemisphere warmings at the beginning of Dansgaard-Oeschger (D-O) events during the last glacial period (21,000-110,000 years ago). Here, we present 'highlights' from a series of model studies aimed at better understanding the changes in the methane budget responsible for these features. Our main conclusion is that the rises in [CH4], both between the LGM and the PI, and at the beginning of D-O events, were likely almost entirely source-driven, with the main factors affecting the oxidizing capacity—changes in air temperatures and emissions of non-methane volatile organic compounds from vegetation—having substantial, but roughly equal and opposite, effects. We also identify a novel cause of glacial-interglacial changes in the carbon-13 content of atmospheric methane, δ13CH4—a complementary constraint on past changes in the methane budget—namely, circulation-driven changes in the amount of methane oxidized by atomic chlorine in the marine boundary layer.

    ABSTRACT Background: Helicobacter pylori has been extensively studied since 1982 it is estimated that 50% of the world population is affected. The literature lacks studies that show the change of its prevalence in the same population over time. Aim: To compare the prevalence of H. pylori in 10 years interval in a population that was submitted to upper endoscopy in the same endoscopy service. Method: Observational, retrospective and cross-sectional study comparing the prevalence of H. pylori in two samples with 10 years apart (2004 and 2014) who underwent endoscopy with biopsy and urease. Patients were studied in three consecutive months of 2004, compared to three consecutive months of 2014. The total number of patients was 2536, and 1406 in 2004 and 1130 in 2014. Results: There were positive for H. pylori in 17 % of the sample as a whole. There was a significant decrease in the prevalence from 19.3% in 2004 to 14.1% in 2014 (p<0.005). Conclusion: There was a 5.2% reduction in the prevalence of H. pylori comparing two periods of three consecutive months with 10 years apart in two equivalent population samples. PMID:27759776

    This study follows 40 children who were participants in a randomized controlled early intervention trial (Kasari et al.) from early childhood (2-5 years of age) to elementary school age (8-10 years). To fully utilize the available longitudinal data, the general linear mixed model was the primary analytical approach. The growth trajectories of joint attention skills (pointing, coordinated joint looking, and showing) and expressive language outcomes in these children were estimated based on five time points during the measurement period. The children were grouped by diagnosis at the last follow-up (autism, autism spectrum disorder (ASD), no diagnosis) and by their original treatment group assignment (joint attention, symbolic play, control), and differences between these groups were evaluated. Results showed that joint attention skills of coordinated joint looking and showing increased over time, and pointing to share interest increased over the first year measured and decreased thereafter. These trajectories were influenced by both original treatment assignment and diagnostic status at follow-up. In addition, a cross-lagged panel analysis revealed a causal relationship between early pointing and later language development. This study highlights the longitudinal and developmental importance of measures of early core deficits in autism, and suggests that both treatment and ASD symptomatology may influence growth in these skills over time.

    Helicobacter pylori from different individuals exhibits substantial genetic diversity. However, the kinetics of bacterial diversification after infection with a single strain is poorly understood. We investigated evolution of H. pylori following long-term infection in the primate stomach; Rhesus macaques were infected with H. pylori strain USU101 and then followed for 10 years. H. pylori was regularly cultured from biopsies, and single colony isolates were analyzed. At 1-year, DNA fingerprinting showed that all output isolates were identical to the input strain; however, at 5-years, different H. pylori fingerprints were observed. Microarray-based comparative genomic hybridization revealed that long term persistence of USU101 in the macaque stomach was associated with specific whole gene changes. Further detailed investigation showed that levels of the BabA protein were dramatically reduced within weeks of infection. The molecular mechanisms behind this reduction were shown to include phase variation and gene loss via intragenomic rearrangement, suggesting strong selective pressure against BabA expression in the macaque model. Notably, although there is apparently strong selective pressure against babA, babA is required for establishment of infection in this model as stains in which babA was deleted were unable to colonize experimentally infected macaques.

  2. Ten Years Record of Decreasing Heat Output From the Hyaloclastite Ridge Formed in the 1996 Gjalp Eruption

    The Gjálp eruption in 1996 formed a 6 km long and 500 m high subglacial hyaloclastite ridge. During the eruption a large depression was formed in the surface of the Vatnajökull ice cap as ice was melted and the meltwater drained away from the eruption site. Ice flow measurements and surface depression mapping have been done annually since the eruption, allowing inflow of ice and volume changes of the depression to be monitored. Taking into account the surface mass balance, these data can be used to estimate heat output from the subglacial ridge. The inflow of ice into the depression mainly from the north is an important part of the overall mass balance budget and was estimated combining surface velocities measurements with numerical 2D, full Stokes, ice flow models. In the first year after the eruption a heat flux of several thousand megawatts was estimated. The heat output decreased to several hundred MW in 1998 and this order of magnitude persisted until 2002. However after 2002 the mountain cooled down and from 2002 to 2005 heat output of the order 101 MW was obtained. These results indicate a 5 - 6 years period with major geothermal activity in the ridge, while in the last 4 years the ridge appears to be much colder. Since the ridge is fully covered by ice, no direct measurements of observations are available to explain this thermal record. Ridges of similar size and shape to that of Gjálp are a prominent feature of the volcanic zones in Iceland. A prominent part of these ridges are consolidated hyaloclastite, formed by alteration of the volcanic glass into palagonite. The rate at which this alteration takes place for ridges formed in short-lived subglacial eruptions is unknown. However, in most cases they have acquired considerable consolidation before glacial erosion could remove the initially unconsolidated hyaloclastite pile. In the oceanic island of Surtsey formed in 1963-1967, the rate of alteration was temperature dependent and took a few years. It is

    This paper presents a new architecture in soft robotics that utilizes particulate jamming technology. A novel concept of actuation is described that utilizes jamming technology to modulate the direction and magnitude of the work performed by a single central actuator. Jamming "activators" modulate work by jamming and unjamming (solidifying and liquifying) a granular medium coupled to a core actuator. These ideas are demonstrated in the Jamming Skin Enabled Locomotion (JSEL) prototype which can morph its shape and achieve locomotion. Next, a new actuator, denoted a Jamming Modulated Unimorph (JMU), is presented in addition to the JSEL topology. The JMU uses a single linear actuator and a discrete number of jamming cells to turn the 1 degree of freedom (DOF) linear actuator into a multi DOF bending actuator. Full characterization of the JMU actuator is presented, followed by a concluding argument for jamming as an enabling mechanism for soft robots in general, regardless of actuation technology.

    This study evaluated the pollution removal and hydrologic performance of five, 10-year old street-side bioretention systems. The bioretention basins were subjected to a series of simulated rainfall events using synthetic stormwater. Four different pollution concentrations were tested on three of the bioretention basins. The four concentrations tested were: A) no pollution; B) typical Australian urban pollutant loads; C) double the typical pollution loads, and; D) five times the typical pollution loads. Tests were also undertaken to determine the levels of contaminant and heavy metals build-up that occurred in the filter media over the 10 year operational life of the bioretention systems. Although highly variable, the overall hydrological performance of the basins was found to be positive, with all basins attenuating flows, reducing both peak flow rates and total outflow volumes. Total suspended solids removal performance was variable for all tests and no correlation was found between performance and dosage. Total nitrogen (TN) removal was positive for Tests B, C and D. However, the TN removal results for Test A were found to be negative. Total phosphorus (TP) was the only pollutant to be effectively removed from all basins for all four synthetic stormwater tests. The study bioretention basins were found to export pollutants during tests where no pollutants were added to the simulated inflow water (Test A). Heavy metal and hydrocarbon testing undertaken on the bioretention systems found that the pollution levels of the filter media were still within acceptable limits after 10 years in operation. This field study has shown bioretention basin pollution removal performance to be highly variable and dependant on a range of factors including inflow pollution concentrations, filter media, construction methods and environmental factors. Further research is required in order to fully understand the potential stormwater management benefits of these systems.

    The North China Plain, the largest agricultural production area in China, is a water-limited region where more than 50% of the nation's wheat and 33% of its maize production is grown. Evapotranspiration (ET) is a major component of the water balance in this agricultural ecosystem. Thus, hydrological cycle is very sensitive to the seasonal and interannual variability in ET. Understanding the variability in ET at different temporal scales and identifying out the dominant factor among the climatic factors (i.e., physical factors), crop factors (i.e., biological factors), and anthropogenic factors (i.e., irrigation) regulating ET is vital for promoting the development of agro-hydrological modeling. However, little is known about how ecosystem-level ET of irrigated cropland responds to these physical and biological factors over the long term, e.g., greater than 10 years. We have operated an eddy-covariance tower in a winter wheat-summer maize cropland for a 10-year period from 2005 through 2015, providing continuous measurements of ET and its relevant variables. The 10-year measurement period covers episodes of extremely high to low annual precipitation and higher air temperatures. The 10-year dataset provides opportunity to investigate the response of site-specific ecosystem ET to the variability of environmental factors. In this study, we reconcile an agro-hydrological model and the observations, to separate the physical and biological controls on ET fluctuations at different temporal scales. First, the model is calibrated carefully based on the observations. Second, a number of model runs are designed to disentangle the influence of climate, irrigation and biological drivers through constrained simulations. The climate drivers include precipitation, air temperature, air humidity, wind speed, and solar radiation, and the biological drivers include leaf area index and leaf-level stomatal conductance. In addition, the impacts of the variability in irrigation on ET will

    The Flat-Plate Solar Array (FSA) Project, a Government-sponsored photovoltaics project, was initiated in January 1975 (previously named the Low-Cost Silicon Solar Array Project) to stimulate the development of PV systems for widespread use. Its goal then was to develop PV modules with 10% efficiency, a 20-year lifetime, and a selling price of $0.50 per peak watt of generating capacity (1975 dollars). It was recognized that cost reduction of PV solar-cell and module manufacturing was the key achievement needed if PV power systems were to be economically competitive for large-scale terrestrial use.

    Maxillofacial trauma is often associated with injuries to the cranium, especially in high-energy trauma. The management of such cases can be challenging and requires close cooperation between oral and maxillofacial surgery and neurosurgical teams. There are few reports in the current literature describing the complications that develop in patients with maxillofacial trauma and traumatic brain injury (TBI). Complications can be categorized as early or late and/or minor and major. The exact definition of complications and their categorization remains a matter of current debate. We present a 10 year retrospective study of complications and their subsequent management in patients receiving maxillofacial and neurosurgical treatment for maxillofacial trauma associated with TBI. The study population consisted of 47 people, excluded from a maxillofacial trauma population of 579 patients. The severity of the trauma was scored as mild, moderate or severe, using the Glasgow Coma Scale at presentation of the Emergency Department. In total 36 patients (76.6%) developed complications. Patients involved in road traffic collision were most likely to develop complications (92.3%). This was followed by falls (66.7%) as mechanism of the injury. Patients aged 60-69 years experienced the highest complication rate (5), followed by patients aged 20-29 years (4.1) and 30-39 years (3.5). The majority of complications were infection and inflammation (36.4%), followed by neurological deficit (24.0%), physiological dysregulation (11.6%) and facial bone deformity (8.3%). Patients who developed no complications, most often presented with mild TBI (72.7%). The most common treatment modality employed to manage complications was pharmacological, followed by antibiotic treatment, conservative treatment and decompression therapy. The mean hospital stay after the trauma for the patients with complications was 28 days. Thirteen patients (36.1%) were transferred to a rehabilitation centre, a nursing

    The amount of time spent on out-of-class activities such as working homework, reading, and studying for examinations is presented for 10 years of an introductory, calculus-based physics class at a large public university. While the class underwent significant change in the 10 years studied, the amount of time invested by students in weeks not containing an in-semester examination was constant and did not vary with the length of the reading or homework assignments. The amount of time spent preparing for examinations did change as the course was modified. The time spent on class assignments, both reading and homework, did not scale linearly with the length of the assignment. The time invested in both reading and homework per length of the assignment decreased as the assignments became longer. The class average time invested in examination preparation did change with the average performance on previous examinations in the same class, with more time spent in preparation for lower previous examination scores (R2 = 0 . 70).

    This study examined whether individuals with different personality types (i.e., overcontrollers, undercontrollers, resilients) had different friendship quality development throughout adolescence. It also investigated whether personality types were indirectly related to romantic relationship quality in young adulthood, via friendship quality development in adolescence. The study employed six waves of longitudinal questionnaire data from Dutch youths who had a romantic relationship when they were young adults. Two age cohorts were followed, from 12 to 21 years and from 16 to 25 years, respectively. Findings showed that resilients reported higher mean levels of friendship quality during adolescence (i.e., more support from, less negative interaction with and less dominance from their best friend) than both overcontrollers and undercontrollers. Through the mean levels of friendship quality throughout adolescence, resilients indirectly experienced higher romantic relationship quality during young adulthood than both overcontrollers and undercontrollers. Thus, results provide support for a developmental model in which adolescent friendship quality is a mechanism linking personality types with young adulthood romantic relationship quality.

    Pre-packed small scale chromatography columns are increasingly used for process development, for determination of design space in bioprocess development, and for post-licence process verifications. The packing quality of 30,000 pre-packed columns delivered to customers over a period 10 years has been analyzed by advanced statistical tools. First, the data were extracted and checked for inconsistencies, and then were tabulated and made ready for statistical processing using the programming language Perl (https://www.perl.org/) and the statistical computing environment R (https://www.r-project.org/). Reduced HETP and asymmetry were plotted over time to obtain a trend of packing quality over 10 years. The obtained data were used as a visualized coefficient of variation analysis (VCVA), a process that has often been applied in other industries such as semiconductor manufacturing. A typical fluctuation of reduced HETP was seen. A Tsunami effect in manufacturing, the effect of propagation of manufacturing deviations leading to out-of-specification products, was not observed with these pre-packed columns. Principal component analysis (PCA) showed that all packing materials cluster. Our data analysis showed that the current commercially available chromatography media used for biopharmaceutical manufacturing can be reproducibly and uniformly packed in polymer-based chromatography columns, which are designed for ready-to-use purposes. Although the number of packed columns has quadrupled over one decade the packing quality has remained stable.

    External causes occupy a high position in the morbidity and mortality profile of youth and children in Brazil, configuring an important public health problem and demanding the deepening of the studies on its characteristics and magnitude. This article describes the profile of emergency care for accidents suffered by children (< 10 years of age) seen at emergency public in some services in Brazil in 2006 and 2007. The data were obtained from survey surveillance component of the Sentinel Service Surveillance System for Violence and Accidents (VIVA), of the Ministry of Health. Children represented about 20% of emergency visits by accidents, with male sex predominance and pre scholars' (2-5 years of age). The greater proportion of accidents (60%) occurred in the household, followed by public ways, school, leisure and sport practice places. Falls and burns had greater participation in the younger age group (< 1), while transport accidents and other types of accidents presented greater frequency among children age 2 to 5. It is necessary to develop education programs since pre school and along the community, aiming of warning about risks and the need of adopt safe behavior in relation to the household environment and the development phase of the child.

    The generation of electricity in nuclear power plants produces an increase in background radiation that could possibly have some impact on the organisms that live in that area. In order to identify and quantify any such possible effect, the natural populations of two sibling species, D. melanogaster and D. simulans, that live in the immediate vicinity of the first Mexican Nuclear Power Plant were analyzed for a period of 10 years. Collections of flies were made at two sites, one close to and one farther from the power plant, during the pre and operational stages of the reactor, and their egg-to-adult viability was analyzed. The data obtained indicate that in both sites, the egg-to-adult viability was generally higher in D. melanogaster than in D. simulans. Further, a relationship was found between egg-to-adult viability and the season of the year (warm-wet or cool-dry season). Some differences were found between the two sites. It may be concluded that there is no negative impact on the Drosophila populations studied. PMID:15106671

    A cementless composite femoral stem was developed with the aim of reducing bone loss secondary to stress shielding. Thirty-one stems were implanted in 27 patients, combined with a cementless acetabular component with polyethylene bearing surface in 30 cases and a bipolar head in 1 case. Patients were followed-up annually with clinical and radiographic evaluation. Fourteen hips underwent dual X-ray absorptiometry (DEXA) scans to monitor postoperative bone mineral density around the stem. The mean follow-up was 10.1 years. The mean Harris hip score improved from 57 to 92. To date, no stem has required revision. All stems are radiographically stable. Acetabular component revision has been required in 8 cases; 3 for liner dissociation and 5 for polyethylene wear. Radiographs and DEXA scans have shown some improvement in bone mineral density (BMD) between the 2 and 5-year follow-up. A cohort of patients displayed improvement in radiographic appearance and BMD in Gruen zone 7. This stem shows evidence of proximal bone preservation and has excellent results at medium to long-term follow-up. The limiting factor in our cohort of patients has been the polyethylene bearing surface.

    A wide spectrum of diseases including reactive processes, infections, lymphomas and metastatic tumors can cause enlargement of lymph nodes. The present study on 4062 patients with lymphadenopathy was conducted in the Department of Cytology, Sestre milosrdnice University Hospital Center, Zagreb, during a 10-year period. Of 4062 patients with lymphadenopathy, 1624 were males and 2438 were females, age range from several months to 85 years. Of 4062 fine needle aspiration procedures, 232/4062 (5.7%) samples were nondiagnostic. Lymph node aspirates were benign in 2640/3830 (69%) and malignant in 1190/3830 (31%) cases. Hematologic disease (Hodgkin lymphoma and non-Hodgkin lymphoma) was diagnosed in 482/1190 (40.5%) and metastases in 708/1190 (59.5%) cases. Of 482 patients with hematologic disease, 48/482 (10%) had Hodgkin lymphomas and 434/482 (90%) non-Hodgkin lymphomas. In the group of malignant lymphadenopathy, there were 212/708 (30%) metastatic squamous cell carcinomas, 177/708 (25%) metastatic adenocarcinomas, 149/708 (21%) metastases of other carcinomas, and 170/708 (24%) metastases of other malignant tumors. The present study confirmed the fine needle aspiration cytology of enlarged head and neck lymph nodes to be an excellent first-line method to investigate the nature of the lesions. PMID:26666101

    Animal derived food is a relevant source of human infections with Salmonella enterica. In this paper we analyse the presence of Salmonella in meat with respect to the observed serovars and their resistance to the fluoroquinolone ciprofloxacin and 3rd generation cephalosporins in the years 2003 to 2012. Data originated from 8176 isolates that were isolated from meat, characterized in the National Reference Laboratory for Salmonella and tested for antimicrobial resistance in the National Reference Laboratory for antimicrobial resistance in this time period. The analysis reveals substantial differences in resistance patterns between isolates from different types of meat and different serovars. Frequent serovars were mostly associated with one type of meat, suggesting an additional influence of specific characteristics of the serovars besides the effect of selection pressure excerted by antimicrobial treatments. Results show a clear increase in resistance to fluoroquinolones and 3rd generation cephalosporins that was most prominent in isolates from poultry meat. Although the number of human infections with Salmonella in Germany decreased sharply in recent years, results indicate a substantial exposure of consumers to Salmonella that are resistant to important antimicrobials via meat.

    Pre-packed small scale chromatography columns are increasingly used for process development, for determination of design space in bioprocess development, and for post-licence process verifications. The packing quality of 30,000 pre-packed columns delivered to customers over a period 10 years has been analyzed by advanced statistical tools. First, the data were extracted and checked for inconsistencies, and then were tabulated and made ready for statistical processing using the programming language Perl (https://www.perl.org/) and the statistical computing environment R (https://www.r-project.org/). Reduced HETP and asymmetry were plotted over time to obtain a trend of packing quality over 10 years. The obtained data were used as a visualized coefficient of variation analysis (VCVA), a process that has often been applied in other industries such as semiconductor manufacturing. A typical fluctuation of reduced HETP was seen. A Tsunami effect in manufacturing, the effect of propagation of manufacturing deviations leading to out-of-specification products, was not observed with these pre-packed columns. Principal component analysis (PCA) showed that all packing materials cluster. Our data analysis showed that the current commercially available chromatography media used for biopharmaceutical manufacturing can be reproducibly and uniformly packed in polymer-based chromatography columns, which are designed for ready-to-use purposes. Although the number of packed columns has quadrupled over one decade the packing quality has remained stable. PMID:27575920

    We report here magnetic resonance imaging measurements performed on suspensions with a bulk solid volume fraction (ϕ_{0}) up to 0.55 flowing in a pipe. We visualize and quantify spatial distributions of ϕ and velocity across the pipe at different axial positions. For dense suspensions (ϕ_{0}>0.5), we found a different behavior compared to the known cases of lower ϕ_{0}. Our experimental results demonstrate compaction within the jammed region (characterized by a zero macroscopic shear rate) from the jamming limit ϕ_{m}≈0.58 at its outer boundary to the random close packing limit ϕ_{rcp}≈0.64 at the center. Additionally, we show that ϕ and velocity profiles can be fairly well captured by a frictional rheology accounting for both further compaction of jammed regions as well as normal stress differences.

    We propose a Widom-like scaling ansatz for the critical jamming transition. Our ansatz for the elastic energy shows that the scaling of the energy, compressive strain, shear strain, system size, pressure, shear stress, bulk modulus, and shear modulus are all related to each other via scaling relations, with only three independent scaling exponents. We extract the values of these exponents from already known numerical or theoretical results, and we numerically verify the resulting predictions of the scaling theory for the energy and residual shear stress. We also derive a scaling relation between pressure and residual shear stress that yields insight into why the shear and bulk moduli scale differently. Our theory shows that the jamming transition exhibits an emergent scale invariance, setting the stage for the potential development of a renormalization group theory for jamming. PMID:27512041

    We report a novel experimental study on the jamming transition of dry fine powders with controlled attractive energy and particle size. Like in attractive colloids dry fine particles experience diffusion-limited clustering in the fluidlike regime. At the jamming threshold fractal clusters crowd in a metastable state at volume fractions depending on attractive energy and close to the volume fraction of hard nonattractive spheres at jamming. Near the phase transition the stress-(volume fraction) relationship can be fitted to a critical-like functional form for a small range of applied stresses sigma approximately (phi-phi(J))(beta) as measured on foams, emulsions, and colloidal systems and predicted by numerical simulations on hard spheres.

    False aneurysm degeneration is a known complication of patch aortoplasty for coarctation of the aortic isthmus. Open surgical treatment consists of prosthetic graft repair of the involved aorta, often requires circulatory arrest to achieve a safe proximal aortic control and perform proximal anastomosis, and finally is associated with substantial perioperative morbidity. Endografting of the diseased aorta is a valuable alternative to open repair, when feasible, with good short and long term results. We now report one more case of false aneurysm ten years after Dacron patch aortoplasty for isthmic coarctation in a 26-year-old woman, successfully treated by endovascular repair via the left common iliac artery, and a complete exclusion of the aneurysm at two year follow-up.

    Abstract It has long been held that schizophrenia and other psychotic disorders have a predominately poor course and outcome. We have synthesized information on mortality, clinical and social outcomes from the ÆSOP-10 multicenter study, a 10-year follow-up of a large epidemiologically characterized cohort of 557 people with first-episode psychosis. Symptomatic remission and recovery were more common than previously believed. Distinguishing between symptom and social recovery is important given the disparity between these; even when symptomatic recovery occurs social inclusion may remain elusive. Multiple factors were associated with an increased risk of mortality, but unnatural death was reduced by 90% when there was full family involvement at first contact compared with those without family involvement. These results suggest that researchers, clinicians and those affected by psychosis should countenance a much more optimistic view of symptomatic outcome than was assumed when these conditions were first described.

    Epidemiological studies have identified recent declines in specific types of adolescent substance use. The current study examined whether these declines varied among youth with and without a history of interpersonal victimization or posttraumatic stress disorder (PTSD). Data for this study come from two distinct samples of youth (12-17 years of age) participating in the 1995 National Survey of Adolescents (N = 3,906) and the 2005 National Survey of Adolescents-Replication (N = 3,423). Results revealed significant declines in adolescents' use of cigarettes and alcohol between 1995 and 2005; use of marijuana and hard drugs remained stable. Of importance, declines in nonexperimental cigarette use were significantly greater among youth without versus with a history of victimization and declines in alcohol use were significantly greater among youth without versus with a history of PTSD.

    Multiple myeloma is a genetically heterogenous disease with a wide variety of characterized genetic aberrations. Until recently, the impact of these aberrations on patient outcome was not known. However, in the last 5-10 years, several genetic markers have been linked to patient outcome. One of the strongest predictors of outcome identified to date is t(4;14)(p16;q32). Although this translocation is tightly linked to chromosome 13 deletions, another poor prognosis marker, it is becoming apparent that the translocation and not the deletion of 13 is the important factor. Unfortunately, despite the known association with outcome, an understanding of the mechanism(s) whereby the translocation contributes to developing and maintaining this aggressive form of myeloma remains elusive.

    Unintentional injury is a significant public health burden for American Indians and Alaska Natives and was the leading cause of death among those aged 1 to 44 years between 1999 and 2004. Of those deaths, motor vehicle-related deaths cause the most mortality, justifying the need for intervention at an American Indian Reservation in Arizona (United States). We describe motor vehicle injury prevention program operations from 2004 through 2013. This community-based approach led by a multidisciplinary team primarily comprised of environmental public health and law enforcement personnel implemented evidence-based strategies to reduce the impact of motor vehicle-related injuries and deaths, focusing on reducing impaired driving and increasing occupant restraint use. Strategies included: mass media campaigns to enhance awareness and outreach; high-visibility sobriety checkpoints; passing and enforcing 0.08% blood alcohol concentration limits for drivers and primary occupant restraint laws; and child car seat distribution and education. Routine monitoring and evaluation data showed a significant 5% to 7% annual reduction of motor vehicle crashes (MVCs), nighttime MVCs, MVCs with injuries/fatalities, and nighttime MVCs with injuries/fatalities between 2004 and 2013, but the annual percent change in arrests for driving under the influence (DUI) was not significant. There was also a 144% increase in driver/front seat passenger seat belt use, from 19% in 2011 before the primary occupant restraint law was enacted to 47% during the first full year of enforcement (2013). Car seat checkpoint data also suggested a 160% increase in car seat use, from less than 20% to 52% in 2013. Implementation of evidence-based strategies in injury prevention, along with employment of key program approaches such as strong partnership building, community engagement, and consistent staffing and funding, can narrow the public health disparity gap experienced among American Indian and Alaska Native

    To understand the distribution of Giardia cysts in drinking water supplies in Seoul, Korea, we collected water samples quarterly at 6 intakes in the Han River, its largest stream and 6 conventional water treatment plants (WTPs) serving drinking water, from 2000 to 2009. Giardia cysts in each of 10 L water were confirmed in 35.0% of intake water samples and the arithmetic mean was 1.65 cysts/10 L (range 0-35 cysts/10 L). The lowest cyst density was observed at Paldang and Kangbuk intakes, and the pollution level was higher at 4 intakes downstream. It seemed that these 4 intakes were under influence of Wangsuk stream at the end of which cysts were found in all samples with the mean of 140 cysts/10 L. The annual mean number of cysts was 0.21-4.21 cysts/10 L, and the cyst level at the second half of the 10 years was about 1/5 of that at first half on average. The cysts were more frequently found in winter, and their mean density was 3.74 cysts/10 L in winter and 0.80-1.08 cysts/10 L in other seasons. All finished water samples collected at 6 WTPs were negative for Giardia in each of 100 L sample for 10 years and cyst removal by physical process was average 2.9-log. It was concluded that conventional water treatment at 6 WTPs of Seoul appears to remove the cysts effectively under the present level of their source water. Domestic wastewater from the urban region could be an important source of Giardia pollution in the river.

    Residual strength results are presented for four composite material systems that have been exposed for up to 10 years to the environment at five different locations on the North American continent. The exposure locations are near where the Bell Model 206L helicopters, which participated in a flight service program sponsored by NASA Langley Research Center and the U.S. Army, were flying in daily commercial service. The composite material systems are (1) Kevlar-49 fabric/F-185 epoxy; (2) Kevlar-49 fabric/LRF-277 epoxy; (3) Kevlar-49 fabric/CE-306 epoxy; and (4) T-300 graphite/E-788 epoxy. Six replicates of each material were removed and tested after 1, 3, 5, 7, and 10 years of exposure. The average baseline strength was determined from testing six as-fabricated specimens. More than 1700 specimens have been tested. All specimens that were tested to determine their strength were painted with a polyurethane paint. Each set of specimens also included an unpainted panel for observing the weathering effects on the composite materials. A statistically based procedure has been used to determine the strength value above which at least 90 percent of the population is expected to fall with a 95-percent confidence level. The computed compression strengths are 80 to 90 percent of the baseline (no-exposure) strengths. The resulting compression strengths are approximately 8 percent below the population mean strengths. The computed short-beam-shear strengths are 83 to 92 percent of the baseline (no-exposure) strengths. The computed tension strength of all materials is 93 to 97 percent of the baseline (no-exposure) strengths.

Routine monitoring and evaluation data showed a significant 5% to 7% annual reduction of motor vehicle crashes (MVCs), nighttime MVCs, MVCs with injuries/fatalities, and nighttime MVCs with injuries/fatalities between 2004 and 2013, but the annual percent change in arrests for driving under the influence (DUI) was not significant. There was also a 144% increase in driver/front seat passenger seat belt use, from 19% in 2011 before the primary occupant restraint law was enacted to 47% during the first full year of enforcement (2013). Car seat checkpoint data also suggested a 160% increase in car seat use, from less than 20% to 52% in 2013. Implementation of evidence-based strategies in injury prevention, along with employment of key program approaches such as strong partnership building, community engagement, and consistent staffing and funding, can narrow the public health disparity gap experienced among American Indian and Alaska Native

    To examine rates of and risk factors for heterosexual transmission of human immunodeficiency virus (HIV), the authors conducted a prospective study of infected individuals and their heterosexual partners who have been recruited since 1985. Participants were recruited from health care providers, research studies, and health departments throughout Northern California, and they were interviewed and examined at various study clinic sites. A total of 82 infected women and their male partners and 360 infected men and their female partners were enrolled. Over 90% of the couples were monogamous for the year prior to entry into the study; < 3% had a current sexually transmitted disease (STD). The median age of participants was 34 years, and the majority were white. Over 3,000 couple-months of data were available for the follow-up study. Overall, 68 (19%) of the 360 female partners of HIV-infected men (95% confidence interval (CI) 15.0-23.3%) and two (2.4%) of the 82 male partners of HIV-infected women (95% CI 0.3-8.5%) were infected. History of sexually transmitted diseases was most strongly associated with transmission. Male-to-female transmission was approximately eight-times more efficient than female-to-male transmission and male-to-female per contact infectivity was estimated to be 0.0009 (95% CI 0.0005-0.001). Over time, the authors observed increased condom use (p < 0.001) and no new infections. Infectivity for HIV through heterosexual transmission is low, and STDs may be the most important cofactor for transmission. Significant behavior change over time in serodiscordant couples was observed. PMID:9270414

    The Pico Mountain Observatory is located in the summit caldera of the Pico mountain, an inactive volcano on the Pico Island in the Azores, Portugal (38.47°N, 28.40°W, Altitude 2225m asl). The Azores are often impacted by polluted outflows from the North American continent and local sources have been shown to have a negligible influence at the observatory. The value of the station stems from the fact that this is the only permanent mountaintop monitoring station in the North Atlantic that is typically located above the marine boundary layer (average MBL heights are below 1200 m and rarely exceed 1300 m) and often receives air characteristic of the lower free troposphere. Measurements of black carbon (BC) mass have been carried out at the station since 2001, mostly in the summer seasons. Here we discuss the BC decadal dataset (2001-2011) collected at the site by using a seven-wavelength AE31 Magee Aethalometer. Measured BC mass and computed Angstrom exponent (AE) values were analysed to study seasonal and diurnal variations. There was a large day-to-day variability in the BC values due to varied meteorological conditions that resulted in different diurnal patterns for different months. The daily mean BC at this location ranged between 0 and ~430 ngm-3, with the most frequently occurring value in the range 0-100 ngm-3. The overall mean for the 10 year period is ~24 ngm-3, with a coefficient of variation of 150%. The BC values exhibited a consistent annual trend being low in winter months and high in summer months, barring year to year variations. To differentiate between BC and other absorbing particles, we analyzed the wavelength dependence of aerosol absorption coefficient and determined a best-fit exponent i.e., the Ångström exponent, for the whole dataset. Visible Ångström exponent (AE: 470-520-590-660 nm) values ranged between 0 and 3.5, with most frequently occurring values in the range 0.85 to 1.25.

    Autoimmune haemolytic anaemia (AHA) is one of the commonest autoimmune disorders of man. It is characterised by the binding of anti-erythrocyte autoantibodies to red blood cells and destruction of the coated cells in the reticulo-endothelial system. Autoimnmune disorders are said to be rare in indigenous African population, probably due to the widespread infectious diseases, which impair host's T-cell immunity. This study is therefore aimed at investigating the pattern of presentation and management outcome of patients with AHA seen over a period of 10 years (June 1988 to May 1998) at the Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife. We retrospectively analysed the records of patients with respect to the clinical, haematological, biochemical and serological features of AHA seen within the study period. Diagnosis was based on laboratory features of haemolytic anaemia and/or a positive direct anti-human globulin (Coombs') test after excluding other causes of haemolytic anaemia. Treatment protocol and outcome were noted in all cases. We identified 13 patients with AHA (7 females, 6 males) aged 6-70 (median, 42) years. Six (42%) had secondary AHA and the remaining 8 presented with primary (idiopathic) AHA. Laboratory evidence of haemolysis (bone marrow erythroid hyperplasia and hyperbilirubinaemia) was found in all cases, while the direct Coomb's test was positive in 10 (76.9%) cases. All the patients had moderate-severe anaemia within the course of the disease, requiring blood transfusion. Remission was induced with prednisolone in all except three cases with secondary AHA who died of the primary disease before AHA could be controlled. Follow-up period post-remission ranged between 1 and 78 months. However, 2 (20%) are still being followed-up till the time of this report. This study agrees with the view that autoimmune disorders are not common in Nigerians, as documented for other Africans. It also shows that steroid therapy (prednisolone) is quite

    On July 15, 2004 the Ozone Monitoring Instrument (OMI) was successfully launched on board of NASA's EOS-Aura spacecraft. OMI is the first of a new generation of UV/VIS nadir solar backscatter imaging spectrometers, which provides nearly global coverage in one day with an unprecedented spatial resolution of 13 x 24 km2. OMI measures solar irradiance and Earth radiances in the wavelength range of 270 to 500 nm with a spectral resolution of about 0.5 nm. OMI is designed and built by the Netherlands and Finland, and is also a third party mission of ESA. The major step that was made in the OMI instrument compared to its predecessors is the use of 2-dimensional detector arrays (CCDs) in a highly innovative small optical design. These innovations enable the combination of a high spatial resolution and a good spectral resolution with daily global coverage. OMI measures a range of trace gases (O3, NO2, SO2, HCHO, BrO, OClO, H2O), clouds and aerosols. Albeit OMI is already 5 years over its design lifetime, the instrument is still fully operational. The successor of OMI is TROPOMI (TROPOspheric Monitoring Instrument) on the Copernicus Sentinel-5 precursor mission, planned for launch in 2016. OMI's unique capabilities rely in measuring tropospheric trace gases with a small footprint and daily global coverage. The unprecedented spatial resolution of the instrument revealed for the first time tropospheric pollution maps on a daily basis with urban scale resolution leading to improved air quality forecasts. The OMI measurements also improve our understanding of air quality and the interaction between air quality and climate change by combining measurements of air pollutants and aerosols. In recent years the data are also used for obtaining high-resolution global emission maps using inverse modelling or related techniques, challenging the bottom-up inventories based emission maps. In addition to scientific research, OMI also contributes to several operational services, including

    Aims: Most industrialised countries have public income maintenance programmes to protect workers in case of disability but studies addressing disability risk of specific professional groups are rare. The objective of this study was to establish a detailed pattern of the nature and extent of occupational disability among construction workers. Methods: A cohort study was set up including 14 474 male workers from the construction industry in Württemberg (Germany) aged 25–64 years who underwent occupational health exams between 1986 and 1992. The cohort was linked to the regional pension register of the manual workers' pension insurance institution to identify workers who were granted a disability pension during the 10 year follow up. All-cause and cause specific standardised incidence ratios (SIR) and 95% confidence intervals (CI) were calculated using disability rates from the general workforce and from all blue collar workers in Germany as references. Results: In total, 2247 (16%) members of the cohort were granted a disability pension. Major causes of disability were musculoskeletal (45%) and cardiovascular diseases (19%). In comparison with the general workforce, construction workers experienced a higher risk of disability from cancer (SIR = 1.26; 95% CI 1.08 to 1.47), respiratory diseases (SIR = 1.27; 95% CI 1.03 to 1.55), musculoskeletal diseases (SIR = 2.16; 95% CI 2.03 to 2.30), injuries/poisoning (SIR = 2.52; 95% CI 2.06 to 3.05), and all causes combined (SIR = 1.47; 95% CI 1.41 to 1.53). When compared with the blue collar reference group, increased risks of disability among construction workers were found for musculoskeletal diseases (SIR = 1.53; 95% CI 1.44 to 1.63), injury/poisoning (SIR = 1.83; 95% CI 1.50 to 2.21), and all causes combined (SIR = 1.11; 95% CI 1.07 to 1.16). Conclusions: Musculoskeletal diseases and external causes are major factors limiting the work capability of construction workers and lead to an increased proportion of occupational

    It is located 650m above sea level along the boundary between the North Caribbean and Pacific slopes, near the Southern end of the volcanic Guanacaste mountain range. In the early 1980s the lake's main outlet was dammed and the outflow was diverted into Arenal Reservoir. Lake Cote was first studied in 1990-1991, and later in 2001, before it was again modified by raising its dam by one meter to use its outflow for hydroelectricity. From 2002 to 2010 it has been monitored twice a year for changes in its limnology. Here I present a summary of its basic characteristics and an analysis of their changes through time. The lake is discontinuous polymictic, and sometimes develops a thermocline at 6m depth that may last for several days as evidenced by the occasional development of an anoxic layer close to the bottom. Since its modification for hydropower production, the surface water temperature has attained higher values than before. Oxygen levels in the lake show periods of hypoxia to anoxia in the hypolimnion, that have become more frequent since modification. Despite its turbid water, the lake has low levels of nutrient concentrations and of chlorophyll a. The trend in these parameters in recent times is a reduction in chlorophyll a and an increase in water transparency, implying a reduction in primary productivity. These changes are discussed in relationship with anthropogenic factors such as the modification of the lake and its management, changes in landscape around the lake and global climate change.

    In 2003 five northern Nigerian states boycotted the oral polio vaccine due to fears that it was unsafe. Though the international responses have been scrutinised in the literature, this paper argues that lessons still need to be learnt from the boycott: that the origins and continuation of the boycott were due to specific local factors. We focus mainly on Kano state, which initiated the boycotts and continued to reject immunisations for the longest period, to provide a focused analysis of the internal dynamics and complex multifaceted causes of the boycott. We argue that the delay in resolving the year-long boycott was largely due to the spread of rumours at local levels, which were intensified by the outspoken involvement of high-profile individuals whose views were misunderstood or underestimated. We use sociological concepts to analyse why these men gained influence amongst northern Nigerian communities. This study has implications on contemporary policy: refusals still challenge the Global Polio Eradication Initiative; and polio remains endemic to Nigeria (Nigeria accounted for over half of global cases in 2012). This paper sheds light on how this problem may be tackled with the ultimate aim of vaccinating more children and eradicating polio. PMID:24294986

    We aimed to investigate long-term outcomes in psychotic major depression patients compared to schizophrenia and bipolar/manic psychosis patients, in an incidence sample, while accounting for diagnostic change. Based on Aetiology and Ethnicity in Schizophrenia and Other Psychoses (ÆSOP and ÆSOP-10), a first episode psychosis cohort was followed-up 10years after first presentation. The Schedules for Clinical Assessment in Neuropsychiatry, WHO Life Chart and Global Assessment of Functioning were used to assess clinical, social and service use outcomes. Seventy-two PMD patients, 218 schizophrenia patients and 70 psychotic bipolar disorder/mania patients were identified at baseline. Differences in outcome between PMD and bipolar patients based on baseline and lifetime diagnosis were minimal. Differences in clinical, social and service use outcomes between PMD and schizophrenia were more substantial with PMD patients showing better outcomes on most variables. However, there was some weak evidence (albeit not quite statistically significant at p<0.05) based on lifetime diagnoses that PMD patients were more likely to attempt suicide (OR 2.31, CI 0.98-5.42, p0.055) and self-harm (OR 2.34, CI 0.97-5.68, p0.060). PMD patients have better social and service use outcomes compared to people with schizophrenia, but may be more likely to attempt suicide or self-harm. This unique profile is important for clinicians to consider in any risk assessment.

    Schizotypal personality disorder (SPD) symptoms or features are common in patients with psychosis and their healthy relatives. However, the long-term stability of these SPD features and therefore their constituting enduring traits underlying vulnerability to psychosis remain to be clarified. Thirty-two patients with psychotic disorders and 29 of their healthy siblings were included from the long-term follow-up study of 89 nuclear families. Participants were clinically assessed by means of a semi-structured diagnostic interview, whereas the Schizotypal Personality Questionnaire-Brief (SPQ-B) was applied for the self-assessment of SPD symptoms. The assessments were carried out upon admission to the study and at follow-up, about 10 years later. The patients had higher scores than their siblings on the SPQ-B both at baseline and follow-up. In addition, self-reported SPD symptoms remained stable over time in total scores and in all the SPQ-B subscores, except for the SPQ-B Disorganization subscale. Self-reported SPD symptoms were stable over the long term among patients with psychotic disorders and their healthy siblings. This finding provides new support for including the SPD construct as a trait measure for studies addressing both vulnerability to psychosis in first-degree relatives of patients with psychosis and long-term persistence of symptoms in patients suffering from psychosis.

    Ceramic-on-ceramic coupling is thought to be a durable alternative to metal- or alumina-on-polyethylene pairing. No evidence exists suggesting superior clinical and radiological results for hydroxyapatite-coated stems versus uncoated stems. The aim of this study is to report the performance of an alumina-on-alumina bearing cementless total hip arthroplasty and to compare stems with a tapered design with and without hydroxyapatite coating. We prospectively analysed the results of cementless tapered femoral stems (40 hydroxyapatite-coated versus 22 uncoated stems), a metal-backed fibre mesh hydroxyapatite-coated socket and alumina-on-alumina pairing. Of 75 hips studied, 62 were available for follow-up (mean of 10.5 years after surgery). The average Harris hip score was 90. Only one hydroxyapatite-coated stem was revised for aseptic loosening. One instance of non-progressive osteolysis was detected around a screw of a cup. All other components showed radiographic signs of stable ingrowth. Hydroxyapatite coating of the stem had no significant impact on the clinical or radiological results. Total hip arthroplasty with the presented implant and pairing provides a durable standard for all patients requiring hip joint replacement against which all newer generations of cementless implants should be judged.

    This study's purpose was to identify distinct publishing trajectories among 442 participants in three prominent mentored health services research career development programs (Veterans Affairs, National Institutes of Health, and Agency for Healthcare Research & Quality) in the 10 years after award receipt and to examine awardee characteristics associated with different trajectories. Curricula vitae (CVs) of researchers receiving awards between 1991 and 2010 were coded for publications, grants, and awardee characteristics. We found that awardees published at constant or increasing rates despite flat or decreasing rates of first-author publications. Senior-author publications rose concurrently with rates of overall publications. Higher overall publication trajectories were associated with receiving more grants, more citations as measured by the h-index, and more authors per article. Lower trajectory groups were older and had a greater proportion of female awardees. Career development awards supported researchers who generally published successfully, but trajectories varied across individual researchers. Researchers' collaborative efforts produced an increasing number of articles, whereas first author articles were written at a more consistent rate. Career development awards in health services research supported the careers of researchers who published at a high rate; future research should further examine reasons for variation in publishing among early career researchers.

    The objective of the current retrospective study was to describe naturally occurring type A botulism in horses in the United States. In the past 10 years, the Botulism Laboratory at the University of Pennsylvania's School of Veterinary Medicine has identified 3 isolated cases and 8 outbreaks of type A botulism in horses via samples positive for Clostridium botulinum type A toxin or spores using the mouse bioassay test. Additional information was obtained by review of submission forms and by telephone or email interviews. Almost all type A cases and outbreaks occurred in the western United States, with Oregon and Idaho overrepresented. Type A toxin was identified in only 1 outbreak; all other identified cases and outbreaks were positive for spores but not preformed toxin. Reported clinical signs included progressive muscle weakness, recumbency, decreased tail and/or tongue tone, dysphagia, respiratory distress, and death. Isolated cases involved foals < or =1 month of age; outbreaks involved horses > or =11 months. One hundred and nineteen horses were potentially exposed to the toxin source; 54 out of 119 showed signs of botulism, and 49 out of 54 affected horses were confirmed dead. The number of horses affected per outbreak ranged from 2 to 24. The source of infection was confirmed to be hay or silage in 6 out of 8 outbreaks and was unknown in 2 out of 8 outbreaks. The present report is the first description of outbreaks of type A botulism in horses and has important implications for prevention and treatment. Based on these findings, type A botulism should be considered in suspect cases of equine botulism in the western United States.

    2014-01-01

    Background Tuberculosis is still the leading cause of illness in the world which accounted for 2.5% of the global burden of disease, and 25% of all avoidable deaths in developing countries. The aim of study was to assess impact of DOTS strategy on tuberculosis case finding and treatment outcome in Gambella Regional State, Ethiopia from 2003 up to 2012 and from 2002 up to 2011, respectively. Methods Health facility-based retrospective study was conducted. Data were collected and reported in quarterly basis using WHO reporting format for TB case finding and treatment outcome from all DOTS implementing health facilities in all zones of the region to Federal Ministry of Health. Results A total of 10024 all form of TB cases had been registered between the periods from 2003 up to 2012. Of them, 4100 (40.9%) were smear-positive pulmonary TB, 3164 (31.6%) were smear-negative pulmonary TB and 2760(27.5%) had extra-pulmonary TB. Case detection rate of smear-positive pulmonary TB had increased from 31.7% to 46.5% from the total TB cases and treatment success rate increased from 13% to 92% with average mean value of being 40.9% (SD = 0.1) and 55.7% (SD = 0.28), respectively for the specified year periods. Moreover, the average values of treatment defaulter and treatment failure rates were 4.2% and 0.3%, respectively. Conclusion It is possible to achieve the recommended WHO target which is 70% of CDR for smear-positive pulmonary TB, and 85% of TSR as it was already been fulfilled the targets for treatments more than 85% from 2009 up to 2011 in the region. However, it requires strong efforts to enhance case detection rate of 40.9% for smear-positive pulmonary TB through implementing alternative case finding strategies. PMID:24444379

    Background: Tuberculosis (TB) is a chronic bacterial disease, which despite the presence of effective drug strategies, still remains a serious health problem worldwide. Estimation of survival rate is an appropriate indicator for prognosis in patients with pulmonary TB. Therefore, this research was designed with the aim of accurate estimation of the survival of patients by taking both the death event and relapse into consideration. Materials and Methods: Based on a retrospective cohort study, information of 2,299 patients with pulmonary TB that had been referred to and treated in Masih Daneshvari Hospital from 2005 to 2015 was reviewed. To estimate the survival of patients with pulmonary TB, the competing risks model, which considered death and relapse as competing events, was used. In addition, the effect of factors affecting the cumulative incidence function (CIF) of death event and relapse was also examined. Results: The effect of risk factors on the CIF of death events and relapse showed that patients’ age, marital status, contact with TB patients, adverse effect of drugs, imprisonment and HIV positivity were factors that affected the CIF of death. Meanwhile, sex, marital status, imprisonment and HIV positivity were factors affecting the CIF of relapse (P <0.05). Considering death and relapse as competing events, survival estimation in pulmonary TB patients showed that survival in this group of patients in the first, third, fifth and tenth year after treatment was 39%, 14%, 7% and 0%, respectively. Conclusion: The use of competing risks model in survival analysis of patients with pulmonary TB with consideration of competing events, enables more accurate estimation of survival. PMID:27403177

    In recent years , laser guided weapons behave very well at destroying the military goals in the local wars, the single-shot probability, effective range and hitting precision getting better. And the semi-active laser guided weapons are the most widely used laser guided weapons. In order to improve the viability and protect important military goals, it's necessary to study the technology to against the semi-active guided weapons. This paper studies the working principle, the advantages and disadvantages of the semi-active guided weapons at first, and analyze the possibility of laser angle deception jamming system working. Then it analyzes the working principle and process of laser angle deception jamming technology. Finally it designs a half-real simulation system of laser angle deception jamming, which consists of semi-active laser guided weapons simulation system and laser angle deception jamming system. The simulation system demonstrates the working process of the laser angle deception jamming system. This paper provides fundamental base for the research on the countermeasure technology of semi-active laser guided weapons.

  12. Socially-marketed rapid diagnostic tests and ACT in the private sector: ten years of experience in Cambodia

    PubMed Central

    2011-01-01

    Whilst some populations have recently experienced dramatic declines in malaria, the majority of those most at risk of Plasmodium falciparum malaria still lack access to effective treatment with artemisinin combination therapy (ACT) and others are already facing parasites resistant to artemisinins. In this context, there is a crucial need to improve both access to and targeting of ACT through greater availability of good quality ACT and parasitological diagnosis. This is an issue of increasing urgency notably in the private commercial sector, which, in many countries, plays an important role in the provision of malaria treatment. The Affordable Medicines Facility for malaria (AMFm) is a recent initiative that aims to increase the provision of affordable ACT in public, private and NGO sectors through a manufacturer-level subsidy. However, to date, there is little documented experience in the programmatic implementation of subsidized ACT in the private sector. Cambodia is in the unique position of having more than 10 years of experience not only in implementing subsidized ACT, but also rapid diagnostic tests (RDT) as part of a nationwide social marketing programme. The programme includes behaviour change communication and the training of private providers as well as the sale and distribution of Malarine, the recommended ACT, and Malacheck, the RDT. This paper describes and evaluates this experience by drawing on the results of household and provider surveys conducted since the start of the programme. The available evidence suggests that providers' and consumers' awareness of Malarine increased rapidly, but that of Malacheck much less so. In addition, improvements in ACT and RDT availability and uptake were relatively slow, particularly in more remote areas. The lack of standardization in the survey methods and the gaps in the data highlight the importance of establishing a clear system for monitoring and evaluation for similar initiatives. Despite these limitations, a

    Soon after its launch in December 1999, the ASTER sensor on the NASA Terra satellite began acquiring infrared data of dynamic surface processes around the world. For the first time in history, well calibrated, relatively high spatial resolution thermal infrared (TIR) data was being collected in more than two spectral bands. These data began a new era in Earth science from space allowing us to examine such diverse topics as the compositional mapping of eolian systems, the accurate detection of subpixel thermal heterogeneities, the relationship between emitted energy from glassy materials and the volcanic processes that formed them, and the thermophysical behavior of the land surface. The TIR subsystem of ASTER has maintained very good radiometric accuracy over the last decade, which is double the original design life. The diligence of the ASTER Science Team to maintain this quality and expand the data through programs such as the night time TIR global map will provide a scientific dataset utilized for many years in the future. For example, one such program started in 2003 was a new collaboration between the ASTER project and the U.S. Geological Survey to help better monitor the explosive volcanoes of the northern Pacific region. The rapid response mode of the instrument has now been automated and linked to a larger-scale and more rapid monitoring alert system operated by the Alaska Volcano Observatory. ASTER TIR data collected under this project are commonly the first detailed views of new activity at these remote volcanoes, with over 1400 TIR images having been acquired for the five most active Kamchatka volcanoes. This presentation will focus on an overview of the science and operational results over the last decade using data from the ASTER TIR sensor. ASTER has the capability to acquire high spatial resolution data from the visible to the TIR wavelength region. Those data, in conjunction with its ability to generate digital elevation models (DEM’s), makes the

    Members of the Infant and Young Child Nutrition (IYCN) Working Group of the Ten Year Strategy for the Reduction of Vitamin and Mineral Deficiencies and several guests and speakers participated in a workshop in Geneva on 10 October 2008. The workshop had two broad objectives. The first objective was to review the evidence base for maternal and IYCN actions and explore how to integrate action throughout the window of opportunity from the prenatal period through the first 2 years of life. The second objective was to discuss the development of the Maternal, Infant, and Young Child Nutrition (MIYCN) Network in relation to the IYCN Working Group's role and structure. The speakers identified a spectrum of efforts needed to improve maternal, infant, and young child nutrition. The group decided to continue discussion on initiating a structure for an MIYCN Network to enhance collaboration.

    geomorphosites, were applied. A problem found in practically all of them is the subjectivity of assessment and, consequently, the difficulty for one operator to replicate results obtained by another. The original objective of the WG was, after four years, to publish guidelines to assess geomorphosites. Nevertheless, the works have shown that the development of general guidelines to be used by all the countries was quite impossible, because the choice of assessment methods depends on the objectives and the context of the research. For this reason, the project of guidelines was abandoned and several of the methods available were developed. These methods have their specificities and are based on several assessment criteria. Nevertheless, it is possible to recognize common and recurrent assessment criteria, like rarity, representativeness and integrity, and others, for example ecological value, palaeogeographic importance, educational value etc., that are dependent on the context of the assessment and on the aims of the research. (3) Mapping. Designing maps is not a simple procedure and in the codification phase (implementation of the map) several points should be considered, in particular, when mapping geomorphosites efforts should be made to identify and use symbols corresponding to semiotic criteria (communicative immediacy, graphic originality and flexibility). Although it is not possible to set up a standardized methodology valid for all purposes, the WG proposed guiding principles for geomorphosite mapping. (4) Education and dissemination. The issue of interpretation of geomorphological heritage, in particular the sensitive question of the adequacy of geoproducts with the public needs and previous knowledge, was also addressed by the WG, and several scholars proposed methods for interpreting geomorphology in a geotourist context. Several questions have not been solved until now and should be addressed in the future: (1) The scale issue in geomorphosite studies is not clearly

  16. Scaling theory for the jamming transition

    NASA Astrophysics Data System (ADS)

    Liu, Andrea J.

    The existence of a critical jamming transition, which marks the onset of rigidity in athermal packings of spheres, suggests that universal physics underlies the origin and nature of rigidity in disordered solids ranging from glasses to foams and granular materials. The jamming transition was originally proposed as a zero-temperature critical point in a non-equilibrium phase diagram in packing density and shear stress. Many studies have documented critical phenomena near the jamming transition, including power-law scaling, diverging length scales and scaling collapse, and theories have been developed to understand these phenomena. However, a number of confusing features have precluded a unified critical scaling analysis of the transition. Here we resolve these issues to present a scaling ansatz for the jamming critical point in terms of density and shear stress. The theory predicts new exponents that we verify with numerical simulations. Work done with C. P. Goodrich and J. P. Sethna and supported by DOE DE-FG02-05ER46199.

    The tiger moth Bertholdia trigona is the only animal in nature known to defend itself by jamming the sonar of its predators - bats. In this study we analyzed the three-dimensional flight paths and echolocation behavior of big brown bats (Eptesicus fuscus) attacking B. trigona in a flight room over seven consecutive nights to determine the acoustic mechanism of the sonar-jamming defense. Three mechanisms have been proposed: (1) the phantom echo hypothesis, which states that bats misinterpret moth clicks as echoes; (2) the ranging interference hypothesis, which states that moth clicks degrade the bats' precision in determining target distance; and (3) the masking hypothesis, which states that moth clicks mask the moth echoes entirely, making the moth temporarily invisible. On nights one and two of the experiment, the bats appeared startled by the clicks; however, on nights three through seven, the bats frequently missed their prey by a distance predicted by the ranging interference hypothesis (∼15-20 cm). Three-dimensional simulations show that bats did not avoid phantom targets, and the bats' ability to track clicking prey contradicts the predictions of the masking hypothesis. The moth clicks also forced the bats to reverse their stereotyped pattern of echolocation emissions during attack, even while bats continued pursuit of the moths. This likely further hinders the bats' ability to track prey. These results have implications for the evolution of sonar jamming in tiger moths, and we suggest evolutionary pathways by which sonar jamming may have evolved from other tiger moth defense mechanisms.

    In order to follow changes in clinical characteristics of IVH catheter-related infections, 183 patients were analyzed in whom microorganisms had been isolated from the tips of IVH catheters over a ten year period (1982-1991) in our university hospital. In 183 patients, the male to female ratio was 2.4, the internal medicine departments (Int. Med. Depts.) to surgical departments (Surg. Depts.) ratio was 0.49, 58% of the patients were over 60 years old, 27% had surgical procedures within 30 days before isolation of organisms, and 44% died before discharge. Malignancies were the highest in number for underlying diseases. The same strains of microorganisms as tip cultures were isolated from blood in around 48% of cases in which blood cultures were employed. In the first 5 years (n = 71) and the latter 5 years (n = 112), the proportion of patients form the Int. Med. Depts. increased from 21 to 40% (p < 0.01), and the proportion of Gram positive bacteria from 44 to 64% (p < 0.01). Their antibiotic sensitivity was, as a whole, slightly lower in the latter 5 years. Among Gram-negative bacteria, P. aeruginosa has shown a tendency to increase (11 to 35%). Clinical features were different depending on the kinds of organisms or types of underlying diseases. Measures against IVH catheter-related infections are discussed.

    Malignant pleural mesothelioma (MPM) is the most common primary malign tumour of pleura. The aim of this study was to evaluate cases of MPM diagnosed and treated in Clinic for Pulmonary Diseases and Tuberculosis "Podhrastovi" during ten-year period (1998-2007). Study is retrospective. The patients were analysed according to age, sex, histopathologic type of the tumour, cantonal distribution in Federation of Bosnia and Herzegovina and regimen of treatment. MPM presented 0,72% (0-1,56% per year) of all hospitalised malignant patients, and the greatest number of registered cases was in the year of 2007. The series included 16 male (57,14%) and 12 female (42,86%). Cases over 64 years old were the most frequent (14-50%) than 45-54 years (7- not 25%). Histopathology types of hospitalised cases of MPM: epitheloid form (8- 28,57%); sarcomatoid form (2- 7,14 %); other forms (18-64,29%). The most patients came from Canton Sarajevo (12-42,86%); ZE-DO canton (8-28,57%) and the UNA-SANA canton (5-17,86%). The therapy applied: chemotherapy (11-39,29%); radiotherapy (3-10,71%); chemotherapy + radiotherapy (4-14,29%); symptomatic therapy (10-35,71 %).
