    The suprabenthos is considered a major food resource for some fish and birds. Moreover, it plays a key role in the food chain and in nutrient regeneration in the surf zone. The aim of this study was to determine the factors that regulate this fauna and the differences between the suprabenthic groups, to study the possibility of seasonal variations and to compare these results with those of other studies conducted in Europe. A study and geographical comparison was conducted of the temporal patterns of the suprabenthos in the swash zone at two sandy beaches on the NE Atlantic coast (Altar and Ladeira beaches) in the NW of Spain. The study was carried out from September 2005 to August 2007 (24 months). To study the fauna, 60 m2 was sampled monthly with a suprabenthic sledge, and a total of 101 species belonging to Peracarida and Decapoda were recorded. Total densities ranged from 0.42 ind·m- 2 to 178.75 ind·m- 2. Ladeira beach showed higher densities and species richness than Altar beach, and the biocoenosis showed a different dynamic over the 24 months and between years and locations. These results indicate that there is no clear seasonality in the dynamic of suprabenthic species, although the variance of Peracarida orders was explained in diverse degree by environmental variables. The environmental models implemented explained between 27.7% and 93.8% of the faunal data, and hydrodynamic factors and daily global irradiance were selected as the best factors to explain the temporal variations.

    Investigation of a beach and its wave conditions is highly requisite for understanding the physical processes in a coast. This study composes spatial and temporal correlation between beach and nearshore processes along the extensive sandy beach of Nagapattinam coast, southeast peninsular India. The data collection includes beach profile, wave data, and intertidal sediment samples for 2 years from January 2011 to January 2013. The field data revealed significant variability in beach and wave morphology during the northeast (NE) and southwest (SW) monsoon. However, the beach has been stabilized by the reworking of sediment distribution during the calm period. The changes in grain sorting and longshore sediment transport serve as a clear evidence of the sediment migration that persevered between foreshore and nearshore regions. The Empirical Orthogonal Function (EOF) analysis and Canonical Correlation Analysis (CCA) were utilized to investigate the spatial and temporal linkages between beach and nearshore criterions. The outcome of the multivariate analysis unveiled that the seasonal variations in the wave climate tends to influence the bar-berm sediment transition that is discerned in the coast.

  7. Dual enrollment as a factor for women transitioning into STEM majors in Montana two-year colleges

    Science.gov (United States)

    Jakes, Penny Jane

    The purpose of this non-experimental, descriptive, quantitative study was to describe the impact high school dual enrollment coursework has had on initial enrollment of women with STEM majors in Montana two-year colleges. The study was designed to find whether or not differences existed for access (initial enrollment), persistence (to third semester), and success (associate's degree, certificate, or transfer to a four-year institution within 150% of program length). The literature review highlighted the need for studies to address the issue of few women in science, technology, engineering, and mathematics (STEM) occupations. One goal of dual enrollment in Montana is to ease transitions from high school to college, including underrepresented populations such as women in STEM fields. The scope of this study was to collect, organize, and interpret data to describe the effect of that effort for women enrolling in STEM majors at two-year colleges in Montana. Baseline information established the demographics of young women who participated in dual enrollment in Montana high schools during 2007-2009. Data analysis described results using attributes of gender, dual enrollment, access, persistence, and success for those enrolled in STEM fields. Results indicated more young women than young men take advantage of dual enrollment in high school and more women than men with dual-enrollment credit initially enroll in college. More men than women major in a STEM field and more men persist and graduate within the STEM fields. Data indicated that 221 students enrolled in a Montana two-year college with DE/DC credit during 2007-2009. Of those, eight women chose STEM majors, six persisted to the third semester, and two completed. It is recommended that a mixed-methods study be conducted to give a deeper level of understanding for enrollment trends and career choice. Longitudinal studies should also be conducted as dual enrollment grows within the state of Montana. Further studies

    This study examines whether (1) older maternal age is associated with increased risk of depressive episodes between four months and two years after first birth and (2) the role of subsequent reproductive, social and child factors in vulnerability to later onset depression. 592 women were recruited in the third trimester of pregnancy in three age-groups (≤ 30 years; 31-36 years,≥37 years); 434 (73%) completed all assessments at four months and two years after birth. Major Depression episodes (MDE) were assessed at four months and two years using the Mini International Neuropsychiatric Interview (MINI). Maternal (age, mode of conception, prior mood symptoms, health), child (temperament, health), reproductive (subsequent fertility treatment, pregnancy, birth, pregnancy loss) and social contextual variables (language background, paid work, practical support, life stresses) were assessed in pregnancy and postnatally using validated questionnaires and structured interview questions. Maternal age was not related to prevalence or timing of MDE. Depression symptoms, poor child health, low practical support at four months and a non-English language background predicted episodes of depression between four months and two years, ps two years after birth. Prevalence for the whole sample was at the lower end of reported community ranges and was comparable early and later in the postpartum period. Screening for depression after childbirth should not be restricted to the early months. Copyright © 2015 Elsevier B.V. All rights reserved.

  2. Morphodynamics of Prograding Beaches

    Science.gov (United States)

    Ruggiero, P.

    2012-12-01

    Long-term coastal evolution often results from the cumulative effects of small residual differences between relatively large signals. In light of dire projections of sea level rise over the next several decades to century, there is a strong societal need for accurate forecasts of net interannual- to decadal-scale coastal change. However, our present understanding of the processes responsible for storm-induced erosion and coastal recession is significantly more advanced than our knowledge of coastal recovery during calm periods. To investigate the processes and morphodynamics associated with progading beaches we synthesize findings from a long-term (15 years) beach morphology monitoring program in the U.S. Pacific Northwest. Most of the beaches along the Columbia River littoral cell (northwest Oregon and southwest Washington) were eroded during the two intense winters of 1997/1998 (a major El Niño event) and 1998/1999 (a moderate La Niña event). Subsequent to these winters the beaches have exhibited net residual progradation of several meters per year resulting in significant shoreline advance. During this same period as many as two to three new foredunes formed with backshore beach profiles accumulating sand at rates of well over 10 m3/m/yr. Interestingly, these large signals of horizontal and vertical coastal advance have occurred on beaches in which nearshore morphological variability is dominated by net offshore sandbar migration. Net offshore sandbar migration follows a three-stage process; bar generation near the shoreline, seaward migration, and bar degeneration in the outer nearshore with a cyclic return period of approximately 4 to 5 years in the region. Gradients in alongshore sediment transport, net onshore directed cross-shore sediment transport within the surf zone, and cross-shore feeding from a shoreface out of equilibrium with forcing conditions may each be partially responsible for the sediment supplied to the beaches and dunes during the study

  3. Beach ridge sedimentology: field observation and palaeoenvironmental interpretation for Anegada Island, British Virgin Islands.

    2014-05-01

    Beach ridge landforms have been observed in different environments and in settings that range from polar to tropical. Their stratigraphy and sedimentology has received a limited amount of discussion in the literature (Tamura, 2012). In coastal geomorphology a beach ridge can be seen as a transitional deposit between onshore and offshore environments. They are regarded as representing high level wave action along a coastline. In the Caribbean the origin of beach ridges has been variously attributed to one of three extreme wave events: extreme swell, extreme storm or tsunami waves. Beach ridges are arranged in beach ridge plains where there is succession of the landforms and can be several kilometres long. Beach ridge accumulation is not continuous and the coast shows alternating accretion and erosion periods. The use of beach ridges as palaeostorm archives is therefore not straightforward. The temporal continuity of beach ridge formation is being assessed on the beach ridge plains of Anegada, British Virgin Islands (Lesser Antilles). This carbonate platform surrounded by a fringing reef contains two beach ridge plains. There are more than 30 ridges in the Atlantic facing- coast and around 10 in the south, Caribbean- facing coast. The sediments of the modern beaches are dominated by the sand fraction and are 100% biogenic origin due to the isolation of Anegada from terrestrial sediment sources. The beach ridge sections have been studied in different area of Anegada beach ridge plains and present low angle seaward-dipping bedding. The sand fraction is dominant in the stratigraphy with a few intact shells. At only one site were coral pebbles deposited in association with the sand fraction. Aeolian deposits represent the upper part of the beach ridges and reflect the stabilization of the beach ridges with ongoing accretion. The sedimentology of the contemporary beach and dunes will be discussed in terms of their implications for understanding beach ridge genesis and its

  6. Gravel beaches nourishment: Modelling the equilibrium beach profile.

    López, I; Aragonés, L; Villacampa, Y; Navarro-González, F J

    2018-04-01

    The erosion of the world's coasts and the shortage of sand to mitigate beach erosion are leading to the increasingly common use of gravel for coastal protection and beach nourishment. Therefore, in order to determine the amount of gravel required for such actions, it is important to know perfectly the equilibrium profile of gravel beaches. However, at present, this profile is obtained from formulas obtained mainly after channel tests, and therefore most of them do not adapt to the real profiles formed by gravel beaches in nature. In this article, 31 variables related to sedimentology, waves, morphology and marine vegetation present on the beaches are studied to determine which are the most influential in the profile. From the study carried out, it is obtained that these variables are the steepness and probability of occurrence of the wave perpendicular to the coast, the profile starting slope (between MWL and -2m), the energy reduction coefficient due to Posidonia oceanica as well as the width of the meadow. Using these variables, different numerical models were generated to predict accurately the gravel beach profile, which will lead to a saving in the volume of material used in the order of 1300m 3 /ml of beach with respect to current formulations, and a greater certainty that the beach nourishment carried out will have the desired effect.

    Sandy beaches are subjected to intense stressors, which are mainly derived from the increasing pattern of beach urbanization. These ecosystems are also a magnet for tourists, who prefer these locations as leisure and holiday destinations, and such activity further increases the factors that have an adverse effect on beaches. In the study reported here the effect of human trampling on macrofauna assemblages that inhabit intertidal areas of sandy beaches was assessed using a BACI design. For this purpose, three contrasting sectors of the same beach were investigated: an urban area with a high level of visitors, a protected sector with a low density of users, and a transitional area with a high level of human occupancy. The physical variables were constant over time in each sector, whereas differences were found in the intensity of human use between sectors. Density variations and changes in the taxonomic structure of the macrofauna with time were shown by PERMANOVA analysis in the urban and transitional locations whereas the protected sector remained constant throughout the study period. The amphipod Bathyporeia pelagica appears sensitive to human trampling pressure and the use of this species as a bioindicator for these types of impact is recommended. Copyright © 2014 Elsevier Ltd.

    Littering of public areas is a significant problem worldwide. Here we evaluate the success of persuasive and demonstrative messages at reducing littering in highly visited river beaches in Argentina. We made an intervention at the beaches which consisted of a personalized verbal request asking visitors to take their litter to the waste cans (persuasive message) while they were exposed to the example of picking up the litter already left on the beach (demonstrative message). We conducted 102 observations distributed over 29 dates, two years and four beaches. Each observation consisted of three or four rounds: before the presence of visitors we cleaned the beaches, during the stay of visitors we made the intervention (once or twice) in two out of the four beaches, and early next morning we estimated the amount of litter left per beach. Litter weight ranged from 0 to 53gvisitor -1 day -1 . Littering per visitor was reduced an average of 35% due to the intervention (p=0.049). We also found differences among beaches (p=0.001), and an increase in littering with crowding (p=0.005). We show for the first time that the personalized request combined with the example of picking up litter is effective in reducing littering in a Latin American country. Copyright © 2016.

    Natural beach is controlled by many factors related to wave and tidal forces, wind, sediment, and initial topography. For this reason, if numerous topographic data of beach is accurately collected, coastal erosion/acceleration is able to be assessed and clarified. Generally, however, many studies on coastal erosion have limitation to analyse the whole beach, carried out of partial area as like shoreline (horizontal 2D) and beach profile (vertical 2D) on account of limitation of numerical simulation. This is an important application for prevention of coastal erosion, and UAV photogrammetry is also used to 3D topographic data. This paper analyses the use of unmanned aerial vehicles (UAV) to 3D map and beach volume change. UAV (Quadcopter) equipped with a non-metric camera was used to acquire images in Songjung beach which is located south-east Korea peninsula. The dynamics of beach topography, its geometric properties and estimates of eroded and deposited sand volumes were determined by combining elevation data with quarterly RTK-VRS measurements. To explore the new possibilities for assessment of coastal change we have developed a methodology for 3D analysis of coastal topography evolution based on existing high resolution elevation data combined with low coast, UAV and on-ground RTK-VRS surveys. DSMs were obtained by stereo-matching using Agisoft Photoscan. Using GCPs the vertical accuracy of the DSMs was found to be 10 cm or better. The resulting datasets were integrated in a local coordinates and the method proved to be a very useful fool for the detection of areas where coastal erosion occurs and for the quantification of beach change. The value of such analysis is illustrated by applications to coastal of South Korea sites that face significant management challenges.

    Beach resilience plays an important role on reducing coastal risk associated to either natural or human induced perturbations affecting the coast. Field experiments were conducted in order to investigate beach resilience in Sisal, Yucatán. Both impermeable and permeable 14-m groins were designed to asses the impact of coastal structures on the beach morphology during a 24-hour period. The experiments were conducted in the spring of 2015 and 2016, allowing the assessment of both structures under similar forcing conditions. Intense sea breeze events (W>12 m/s) generated high-angle short-waves, driving alongshore transport in the swash zone. Wind, waves, tides, and currents were measured concurrently and are correlated with beach morphology evolution data derived from intense monitoring conducted during the structure deployment. The impermeable structure induced a significant beach accretion (>60 m3/day) in the updrift side of the structure causing a tremendous impact downdrift. On the other hand, the permeable groin induced a smaller but still significant accretion (40 m3/day), allowing sediment bypass throughout the structure. Furthermore, the beach surveying continued after structures removal in order to estimate the beach recovery capability. Field observations show that the impact of the structure on the morphology is negligible six days after structure removal for the impermeable groin and only one day for the permeable structure. The latter suggests the high beach resilience of the study area. We acknowledge field support provided by researchers and students at the LIPC-UNAM. Financial support was provided by CONACYT (Projects LN271544 and Cátedras 1146), DGAPA-UNAM (PAPIIT-IN107315) and Grupo BARI.

  1. The Virginia Beach shallow ground-water study

    Science.gov (United States)

    Johnson, Henry M.

    1999-01-01

    IntroductionVirginia Beach is a rapidly growing city of more than 425,000 people. Sources of fresh water within the city, however, are limited. Prior to 1998, the Virginia Beach Public Utilities Department met the city's water needs by purchasing treated drinking water from the City of Norfolk. Because Norfolk had to meet its own requirements, the amount of water available to Virginia Beach was limited to about 30 million gallons per day (mgd) and even less during droughts. This water supply was supplemented with ground water from city-owned, community, and private wells. In many parts of the city, however, ground water cannot be used because of high concentrations of chloride, iron, and (or) sulfur, which give the water an unpleasant taste.In early 1998, a pipeline came on-line that can carry up to 45 mgd of water from Lake Gaston to Virginia Beach. The Gaston pipeline has alleviated concerns about water supply and quality for most residents living north of the "Green Line." These residents primarily use ground water only for small-scale domestic activities such as watering lawns, filling ponds and pools, and washing cars. City water and sewer services have been extended beyond the Green Line into the "Transition Area." Residents and businesses south of the Transition Area, however, continue to rely on ground water to meet most of their needs for potable and non-potable water. To help assure a continued, reliable supply of ground water, the U.S. Geological Survey (USGS), in cooperation with the City of Virginia Beach Public Utilities Department, has begun an assessment of the shallow ground-water resources underlying the City of Virginia Beach.

    2013-01-01

    The aims of the present study were to establish a detailed and representative record of landing techniques (two-, left-, and right-footed landings) in professional beach volleyball and compare the data with those of indoor volleyball. Beach volleyball data was retrieved from videos taken at FIVB World Tour tournaments. Landing techniques were compared in the different beach and indoor volleyball skills serve, set, attack, and block with regard to sex, playing technique, and court position. Significant differences were observed between men and women in landings following block actions (χ2(2) = 18.19, p volleyball revealed overall differences both in men (χ2(2) = 161.4, p volleyball players land more often on both feet than indoor volleyball players. Besides the softer surface in beach volleyball, and therefore resulting lower loads, these results might be another reason for fewer injuries and overuse conditions compared to indoor volleyball. Key Points About 1/3 of all jumping actions in beach volleyball result in a landing on one foot. Especially following block situations men land on one foot more often than women. Landing techniques are related to different techniques and positions. Landings on one foot are less common in beach volleyball than indoor volleyball. This could be a reason for fewer injuries and overuse conditions. PMID:24149150

    BACKGROUND: We used the Nordic Arthroplasty Register Association database to evaluate whether age, sex, preoperative diagnosis, fixation, and implant design influence the risk of revision arthroplasty due to periprosthetic fracture within two years from operation of a primary total hip replacement....... METHODS: Included in the study were 325,730 cemented femoral stems and 111,899 uncemented femoral stems inserted from 1995 to 2009. Seven frequently used stems (two cemented stems [Exeter and Lubinus SP II] and five uncemented stems [Bi-Metric, Corail, CLS Spotorno, ABG I, and ABG II]) were specifically...... studied. RESULTS: The incidence of revision at two years was low: 0.47% for uncemented stems and 0.07% for cemented stems. Uncemented stems were much more likely to have this complication (relative risk, 8.72 [95% confidence interval, 7.37 to 10.32]; p

  17. Japanese two-year-olds use morphosyntax to learn novel verb meanings.

    Matsuo, Ayumi; Kita, Sotaro; Shinya, Yuri; Wood, Gary C; Naigles, Letitia

    2012-06-01

    Previous research has found that children who are acquiring argument-drop languages such as Turkish and Chinese make use of syntactic frames to extend familiar verb meanings (Göksun, Küntay & Naigles, 2008; Lee & Naigles, 2008). This article investigates whether two-year-olds learning Japanese, another argument-drop language, make use of argument number and case markings in learning novel verbs. Children watched videos of novel causative and non-causative actions via Intermodal Preferential Looking. The novel verbs were presented in transitive or intransitive frames; the NPs in the transitive frames appeared 'bare' or with case markers. Consistent with previous findings of Morphosyntactic Bootstrapping, children who heard the novel verbs in the transitive frame with case markers reliably assigned those verbs to the novel causative actions.

    Children with traumatic brain injury (TBI) are at risk for social impairment, but research has yet to document the trajectory of these skills post-injury and factors that may predict social problems. This study addressed these gaps in knowledge, reporting on findings from a prospective, longitudinal follow-up study that investigated social outcomes post-injury and explored factors contributing to these outcomes at two years post-injury. The sample included 113 children, 74 with TBI and 39 typically developing (TD) controls. TBI participants were recruited on presentation to the hospital. Parents rated pre-injury function at that time, and all children underwent magnetic resonance imaging (MRI). Participants were followed up at two years post-injury. Outcomes were social adjustment, social participation, social relationships, and social cognition. Predictors of social outcomes examined included brain lesion characteristics, child cognition (6 months post-TBI), and behavior and environmental factors (pre-injury and two years). Reduced social adjustment (p = 0.011) and social participation (p Poor social adjustment was predicted by externalizing behavior problems and younger age at injury. Reduced social participation was linked to internalizing behavior problems. Greater lesion volume, lower socioeconomic status, and family burden contributed to poorer social relationships, whereas age at injury predicted social cognition. Within the TBI group, 23% of children exhibited social impairments. Younger age at injury, greater pre-injury, and current behavior problems and family dysfunction, and poorer intelligence quotient (IQ), processing speed, and empathy were linked to impairment. Further follow-up is required to track social recovery and the influences of cognition, brain, and environment over time.

    Full Text Available Purpose: The use of radiation therapy (RT for non-melanoma skin cancer (NMSC has been changing throughout the last century. Over the last decades, the use of radiotherapy has surged with the development of new techniques, applicators, and devices. In recent years, electronic brachytherapy (eBT devices that use small x-ray sources have been introduced as alternative to radionuclide dependence. Nowadays, several devices have been incorporated, with a few series reported, and with a short follow-up, due to the recent introduction of these systems. The purpose of this work is to describe the clinical results of our series after two years follow-up with a specific eBT system. Material and methods: This is a prospective single-center, non-randomized pilot study, to assess clinical results of electronic brachytherapy in basal cell carcinoma using the Esteya® system. In 2014, 40 patients with 60 lesions were treated. Patient follow-up on a regular basis was performed for a period of two years. Results: Twenty-six patients with 44 lesions achieved two years follow-up. A complete response was documented in 95.5% of cases. Toxicity was mild (G1 or G2 in all cases, caused by erythema, erosion, or alopecia. Cosmesis was excellent in 88.6% of cases, and good in the rest. Change in pigmentation was the most frequent cosmetic alteration. Conclusions : This work is special, since the equipment’s treatment voltage was 69.5 kV, and this is the first prospective study with long term follow-up with Esteya®. These preliminary report show excellent results with less toxicity and excellent cosmesis. While surgery has been the treatment of choice, certain patients might benefit from eBT treatment. These are elderly patients with comorbidities or undergoing anticoagulant treatment as well as those who simply refuse surgery or might have other contraindications.

  3. Aeolian transport of seagrass ( Posidonia oceanica ) beach-cast to terrestrial systems

    KAUST Repository

    Jiménez, Maria A.

    2017-06-29

    The annual export of the Mediterranean seagrass (Posidonia oceanica) litter to adjacent beaches and coastal dunes was quantified by examining the fortnight evolution of seagrass beach-cast volume on two beaches in the NW Mediterranean (Son Real and Es Trenc, Mallorca Island, Spain) for two years and analyzing the wind speed and direction obtained from the closest Meteorological Spanish Agency surface weather stations. The decomposition stage of the deposits was examined by analyzing the total hydrolysable amino acids, its percentage distribution and derived degradation indexes. Prevalent winds exceeding 6 m s−1, the coastline morphology and type of terrestrial vegetation determine the annual dynamics of the seagrass beach-cast. In the most protected beach (Son Real) the seagrass beach-cast remained nearly stationary during the two studied years while it exhibited wide annual fluctuations in the less protected one (Es Trenc). The amounts of P. oceanica wrack washed on Son Real and Es Trenc beaches, respectively, were estimated at 309 kg DW m coastline−1 yr−1 and 1359 kg DW m coastline−1 yr−1. They supplied between 20 kg CaCO3 m coastline−1 yr−1 and 47 kg CaCO3 m coastline−1 yr−1. Between 54% (Son Real) and 70% (Es Trenc) of seagrass beach-cast, respectively accounting for 1.5 kg N m coastline−1 yr−1 and 8.6 kg N m coastline−1 yr−1, were annually exported from the beaches to adjacent dune systems. Our results reveal that Mediterranean seagrass meadows might be an important source of materials, including sand and nutrients, for adjacent terrestrial systems, able to support their functioning.

  4. Research Not Foreign to Two-Year Colleges

    Science.gov (United States)

    Whipple-Vanpatter, Georgianna

    1998-10-01

    Why is research a word not usually found in the two-year college vocabulary? At a 2YC3 conference held in New York in 1995, it appeared that undergraduate research in two-year colleges tended to be a very regional and limited undertaking. Webster defines research as: "1. Careful or diligent search; 2. Studious inquiry or examination; and 3. The collecting of information about a particular subject." These are things performed in our laboratories, so why not do them in a formal setting, making the students more aware that they are performing research? The challenge is to develop an investigative spirit in ourselves and thus in our students. This does not mean that we have to be inventing new procedures or making profound discoveries. Instructors, however, hesitate to implement a research program, claiming a lack of equipment, time, interest, training, or support. By sharing my experience, I hope it will make it easier for you to overcome some of these obstacles and enjoy the experiences of student research.

    Experience of the first two years of an orthopaedic geriatric rehabilitation unit is described. There were 325 admissions comprising 271 females and 54 males. The predominant diagnosis was fracture of the proximal femur. Average length of stay in the unit was 43 days for males and 36.7 days for females. 75.9% of patients admitted from home returned there and 66.1% of patients admitted from residential care returned to similar accommodation. In the first year there was a fall of 13.5 days in the average length of stay for elderly females with proximal femoral fracture, resulting in 2175 less bed days for this diagnosis. This improvement has continued.

    The Taiwan Photon Source (TPS), a 3-GeV third generation synchrotron light source, was commissioned in 2014 December and is now currently operated in top-up mode at 300mA for users. During the past two years, the machine was completed to meet design goals with among others the installation of superconducting cavities (SRF), the installation of insertion devices (ID) and the correction of vacuum chamber structure downstream from the IDs. The design goal of 500mA beam current was achieved with a total accumulated beam dose of more than 1000Ah, resulting in three orders of magnitude reduction of out-gassing. As the beam current was increased, a few vacuum problems were encountered, including vacuum leaks, unexpected pressure bursts, etc. Vacuum related issues including high pressure events, lessons learned and operational experience will be presented and discussed in this paper.

    Anthropogenic climate change is driving sea level rise, leading to numerous impacts on the coastal zone, such as increased coastal flooding, beach erosion, cliff failure, saltwater intrusion in aquifers, and groundwater inundation. Many beaches around the world are currently experiencing chronic erosion as a result of gradual, present-day rates of sea level rise (about 3 mm/year) and human-driven restrictions in sand supply (e.g., harbor dredging and river damming). Accelerated sea level rise threatens to worsen coastal erosion and challenge the very existence of natural beaches throughout the world. Understanding and predicting the rates of sea level rise and coastal erosion depends on integrating data on natural systems with computer simulations. Although many computer modeling approaches are available to simulate shoreline change, few are capable of making reliable long-term predictions needed for full adaption or to enhance resilience. Recent advancements have allowed convincing decadal to centennial-scale predictions of shoreline evolution. For example, along 500 km of the Southern California coast, a new model featuring data assimilation predicts that up to 67% of beaches may completely erode by 2100 without large-scale human interventions. In spite of recent advancements, coastal evolution models must continue to improve in their theoretical framework, quantification of accuracy and uncertainty, computational efficiency, predictive capability, and integration with observed data, in order to meet the scientific and engineering challenges produced by a changing climate.

    As NASA communication networks upgrade to higher frequencies, such as Ka-Band, atmospherically induced attenuation can become significant. This attenuation is caused by rain, clouds and atmospheric gases (oxygen and water vapor), with rain having the most noticeable effects. One technique to circumvent the increase in attenuation is to operate two terminals separated by a distance that exceeds the average rain cell size. The fact that rain cells are of finite size can then be exploited by rerouting the signal to the terminal with the strongest link. This technique, known as site diversity, is best suited for climates that have compact (less than 2km) and intense rain cells such as in Guam. In order to study the potential diversity gain at the Tracking and Data Relay Satellite (TDRS) Remote Ground Terminal (GRGT) complex in Guam a site test interferometer (STI) was installed in May of 2010. The STI is composed of two terminals with a 900m baseline that observe the same unmodulated beacon signal broadcast from a geostationary satellite (e.g., UFO 8). The potential site diversity gain is calculated by measuring the difference in signal attenuation seen at each terminal. Over the two years of data collection the cumulative distribution function (CDF) of the site diversity gain shows a better than 3 dB improvement for 90% of the time over standard operation. These results show that the use of site diversity in Guam can be very effective in combating rain fades.

    Cow's milk allergy (CMA) epidemiology seems to be changing over time, with an increase in prevalence and persistence. Our aim was to characterise a population of children with CMA beyond two years of age, followed up in a Paediatric Allergy Clinic at the tertiary care level. Retrospective study of children with persistent CMA diagnosed from January 1997 to June 2006. Medical records were analysed regarding: clinical presentation, follow-up, treatment and acquisition of tolerance. Data analysis was performed using Excel 2007 for Windows. Seventy-nine children were included, with mean age at first symptoms of 3 months. The symptoms were immediate in 93%, with cutaneous (87.3%), gastrointestinal (55.7%) and respiratory (25.3%) manifestations. During the follow-up period, 30% developed atopic eczema, 52% asthma and 35% rhinoconjunctivitis. A family history of atopy was identified in 53%. The majority presented increased serum total IgE (376+/-723 KU/l) and positive skin prick test (SPT) to cow's milk (CM) (79%). SPT to goat's milk was positive in 2/3 of cases. Fifty-five percent had at least one accidental exposure to CM (severe reactions in 6%). During CM elimination diet, 35% were initially given an extensively hydrolysed formula, 17% a soy formula, and 48% both. By the age of 10 years, 44% of children persisted with CMA. Our population of CM allergic children presented immediate symptoms with cutaneous expression in the majority. Severe reactions were common on accidental exposure. By the age of 10 years, 44% maintained CMA, highlighting the importance of a multidisciplinary follow-up. Copyright 2009 SEICAP. Published by Elsevier Espana. All rights reserved.

  8. Recharge into a shingle beach

    Keating, T.

    1984-04-01

    Traditionally, groundwater recharge in the U.K. has been calculated by the Penman method on a monthly basis, using values of potential evaporation derived from averaged meteorological data and monthly totals of rainfall. Recent work by K.W.F. Howard and J.W. Lloyd has shown that these monthly totals considerably underestimate recharge calculated over shorter time periods and they suggested that 1-day, or at worst, 10-day intervals should be used. In this paper field experiments to measure recharge into a shingle beach are reported. These experiments were made with a lysimeter over a 6-yr. period and have shown that recharge into the shingle occurs whenever significant precipitation occurs, even during the summer months. The Penman model is shown to be unrealistic for estimating recharge into such a beach and an alternative model for calculating recharge is proposed. This model is shown to yield good results.

    Nationwide, approximately 17% of all two-year colleges offer geoscience degrees, and the two-year college population is growing rapidly. Although 33% of two-year college students are members of underrepresented minorities, this group earned only 12% of geoscience associate's degrees in 2008. Thus, engaging with two-year colleges represents both a potential rich source of diversity for the field and an area where much work remains to be done. Through the National Science Foundation's Opportunities for Enhancing Diversity in the Geosciences Program, we conducted a workshop at the American Geophysical Union's (AGU) Headquarters in Washington DC in July, 2012. This workshop gathered over fifty participants including two-year college Earth and space science faculty who conduct research with their students, as some of their four-year college partners, members of other scientific organizations, and federal employees working to support Earth and space science education. Our workshop provided the opportunity for two-year college faculty to increase their awareness of existing and successful research programs in the Earth and space sciences, and helped to identify relevant challenges to participation for both students and faculty. Additionally, faculty from four-year Earth and space science programs who have successfully transitioned two-year college students into their programs sparked a discussion of the issues and barriers involved in that process. Outcomes from this workshop include dissemination of best practices for doing student-faculty research in Earth and space sciences at two-year colleges, at nearby four-year campuses, and national summer research programs. Our workshop built on previous efforts to coalesce a community of practice made up of two-year college faculty who conduct research in the Earth and space sciences with their students and those who are interested in partnering with or supporting them. Finally, the planning workshop helped to define the path

  11. Classification of beach response to extreme storms

    2017-10-01

    Extreme storms are responsible for rapid changes to coastlines worldwide. During the 2013/14 winter, the west coast of Europe experienced a sequence of large, storm-induced wave events, representing the most energetic period of waves in the last 60 years. The southwest coast of England underwent significant geomorphological change during that period, but exhibited a range of spatially variable and complex morphological responses, despite being subjected to the same storm sequence. Here, we use the 2013/14 storm response along the southwest coast of England as a natural field laboratory and explain this variability in storm response through the introduction and evaluation of a new classification of how sandy and gravel beaches respond to extreme storms. Cluster analysis was conducted using an unique data set of pre- and post-storm airborne Light Detection and Ranging (LiDAR) data from 157 beach sites based on the net volumetric change (dQnet) and a novel parameter, the longshore variation index (LVI) which quantifies the alongshore morphological variability in beach response. Four main beach response types were identified: (1) fully exposed beaches that experienced large and alongshore uniform sediment losses (dQnet ≈ 100 m3·m- 1); (2) semi-exposed beaches that experienced medium alongshore uniform sediment losses (dQnet ≈ 50 m3·m- 1); (3) sheltered short beaches that experienced limited net sediment change and alongshore variability in beach response; and (4) sheltered long beaches that experienced considerable alongshore variability in beach response and large gross sediment change, but limited net sediment change. The key factors in determining the type of beach response are: exposure to the storm waves, angle of storm wave approach and the degree to which the beach is embayed. These factors are universally applicable on many exposed coastlines worldwide, so the response classification presented here is expected to be widely applicable.

    Beaches are the places where the interaction of the land and sea takes place, and it is under the influence of many environmental factors, including meteorological and oceanic ones. To understand the evolution or changes of beaches, it may require constant monitoring. One way to monitor the beach changes is to use optical cameras. With careful placements of ground control points, land-based optical cameras, which are inexpensive compared to other remote sensing apparatuses, can be used to survey a relatively large area in a short time. For example, we have used terrestrial optical cameras incorporated with ground control points to monitor beaches. The images from the cameras were calibrated by applying the direct linear transformation, projective transformation, and Sobel edge detector to locate the shoreline. The terrestrial optical cameras can record the beach images continuous, and the shorelines can be satisfactorily identified. However, the terrestrial cameras have some limitations. First, the camera system set a sufficiently high level so that the camera can cover the whole area that is of interest; such a location may not be available. The second limitation is that objects in the image have a different resolution, depending on the distance of objects from the cameras. To overcome these limitations, the present study tested a quadcopter equipped with a down-looking camera to record video and still images of a beach. The quadcopter can be controlled to hover at one location. However, the hovering of the quadcopter can be affected by the wind, since it is not positively anchored to a structure. Although the quadcopter has a gimbal mechanism to damp out tiny shakings of the copter, it will not completely counter movements due to the wind. In our preliminary tests, we have flown the quadcopter up to 500 m high to record 10-minnte video. We then took a 10-minute average of the video data. The averaged image of the coast was blurred because of the time duration of

    Arthroscopic shoulder surgery can be performed in both the beach chair and lateral decubitus positions. The beach chair position is a reliable, safe, and effective position to perform nearly all types of shoulder arthroscopic procedures. The advantages of the beach chair position include the ease of setup, limited brachial plexus stress, increased glenohumeral and subacromial visualization, anesthesia flexibility, and the ability to easily convert to an open procedure. This position is most commonly used for rotator cuff repair, subacromial decompression, and superior labrum anterior-to-posterior repair procedures. To perform arthroscopy surgery in the beach chair position successfully, meticulous care during patient positioning and setup must be taken. In this Technical Note, we describe the necessary steps to safely and efficiently prepare patients in the beach chair position for arthroscopic shoulder surgery.

  7. Subsurface Flow and Moisture Dynamics in Response to Swash Motions: Effects of Beach Hydraulic Conductivity and Capillarity

    2017-12-01

    A combined field and numerical study was conducted to investigate dynamics of subsurface flow and moisture response to waves in the swash zone of a sandy beach located on Cape Henlopen, DE. A density-dependent variably saturated flow model MARUN was used to simulate subsurface flow beneath the swash zone. Values of hydraulic conductivity (K) and characteristic pore size (α, a capillary fringe property) were varied to evaluate their effects on subsurface flow and moisture dynamics in response to swash motions in beach aquifers. The site-specific modeling results were validated against spatiotemporal measurements of moisture and pore pressure in the beach. Sensitivity analyses indicated that the hydraulic conductivity and capillary fringe thickness of the beach greatly influenced groundwater flow pathways and associated transit times in the swash zone. A higher value of K enhanced swash-induced seawater infiltration into the beach, thereby resulting in a faster expansion of a wedge of high moisture content induced by swash cycles, and a flatter water table mound beneath the swash zone. In contrast, a thicker capillary fringe retained higher moisture content near the beach surface, and thus, significantly reduced the available pore space for infiltration of seawater. This attenuated wave effects on pore water flow in the unsaturated zone of the beach. Also, a thicker capillary fringe enhanced horizontal flow driven by the larger-scale hydraulic gradient caused by tides.

    1991-01-01

    Owing to Oman's geographic position and long coastal line, the coastal areas of Oman are particularly vulnerable to oil pollution from normal tanker operations, illegal discharges, and accidental spills as well as local sources of oil input. UNEP carried out a survey on the coasts of Oman to determine the major sources of oil pollution and concluded that the major shoreline pollution problems in Oman arose from operational discharges of oil from passing vessels traffic. The oil, because of the high sea and air temperatures in the area, was subjected to relatively high rates of evaporation and photo-oxidation and tended to arrive at the coast as heavy petroleum particulate residues (tar balls). The aim of the present study was to measure the loads of tar balls in Omani coastal areas and to identify the source of oil pollutants on beaches

    This study aims to determine the concentrations of total coliforms and Escherichia coli (E. coli) in beach water, Teluk Kemang beach. This study was also aimed to determine relationship between total coliforms, E. coli and physicochemical parameters. As perceived health symptoms among beach visitors are rarely incorporated in beach water studies, this element was also assessed in this study. A total of eight water sampling points were selected randomly along Teluk Kemang beach. Total coliforms concentrations were found between 20 and 1940 cfu/100ml. E. coli concentrations were between 0 and 90 cfu/100ml. Significant correlations were found between total coliforms and E. coli with pH, temperature and oxidation reduction potential. Skin and eyes symptoms were the highest reported though in small numbers. Microbiological water quality in Teluk Kemang public beach was generally safe for recreational activities except sampling location near with sewage outfall. Copyright © 2013 Elsevier Ltd.

    The response of a rocky beach to different possible combinations of hydrodynamic conditions (tides, waves, oceanic currents) has been little studied. In this work, the morphodynamic response to different hydrodynamic forcing is evaluated from sedimentological and geomorphological analysis in seasonal and medium term (19 years) scale in Palmeras beach, located in the southwest of Gorgona Island National Natural Park (NNP), a mesotidal rocky island on the Colombian Pacific continental shelf. Palmeras is an important nesting area of two types of marine turtles, with no anthropogenic stress. In the last years, coastal erosion has reduced the beach width, restricting the safe areas for nesting and conservation of these species. Until now, the sinks, sources, reservoirs, rates, and paths of sediments were unknown, as well as their hydrodynamic forcing. The beach seasonal variability, from October 2010 to August 2012, was analyzed based on biweekly or monthly measurements of five beach profiles distributed every 200 m along the 1.2 km of beach length. The main paths for sediment transport were defined from the modeling of wave currents with the SMC model (Coastal Modeling System), as well as the oceanic currents, simulated for the dry and wet seasons of 2011 using the ELCOM model (Estuary and Lake COmputer Model). Extreme morphologic variations over a time span of 19 years were analyzed with the Hsu and Evans beach static equilibrium parabolic model, from one wave diffraction point which dominates the general beach plan shape. The beach lost 672 m3/m during the measuring period, and erosional processes were intensified during the wet season. The beach trends responded directly to a wave mean energy flux change, resulting in an increase of up to 14 m in the width northward and loss of sediments in the beach southward. This study showed that to obtain the integral morphodynamic behavior of a rocky beach it is necessary to combine information of hydrodynamic, sedimentology

    The amount of marine debris in the environment is increasing worldwide, which results in an array of negative effects to biota. This study provides the first account of macrodebris on the beach and microplastics in the sediment (shoreline and infralittoral) in relation to tourism activities in Slovenia. The study assessed the quality and quantity of macrodebris and the quality, size and quantity of microplastics at six beaches, contrasting those under the influences of tourism and those that were not. Beach cleanliness was estimated using the Clean Coast Index. Tourism did not seem to have an effect on macrodebris or microplastic quantity at beaches. Over 64% of macrodebris was plastic, and microplastics were ubiquitous, which calls for classification of plastics as hazardous materials. Standard measures for marine debris assessment are needed, especially in the form of an all-encompassing debris index. Recommendations for future assessments are provided for the Adriatic region.

    Pianca, C.; Holman, R. A.; Siegle, E.

    2016-02-01

    The most curious morphological features observed on beaches are the cusps. Due to their rhythmic spacing, beach cusps have attracted many observers and many, often contradictory, theories as to their form. Moreover, most of the research about beach cusps has focused on their formation. Few had available long time series to study such things as the variability of alongshore and cross-shore position and spacing on the cusp field, the presence, longevity and interactions between higher and lower sets of cusps, and the processes by which cusp fields extend, shrink or change length scale. The purpose of this work is to use long-term data sets of video images from two study sites, an intermediate (Duck, USA, 26 years) and a reflective beach (Massaguaçu, Brazil, 3 years), to investigate the temporal and spatial changes of cusps conditions. Time-evolving shoreline data were first extracted using an algorithm called ASLIM (Pianca et al 2015). Cusps were then identified based on the band-passed variability of time exposure image data about this shoreline as a function of elevation relative to MSL. The identified beaches cusps will be analyzed for cusp spacing, positions (upper or lower cusps), alongshore variability, merging events, percentage of cusp events, patterns of the events and time scales of variability. Finally, the relationship of these characteristics to environmental conditions (wave, tides, beach conditions) will be studied.

  9. Age and morphodynamics of a sandy beach fronted by a macrotidal mud flat along the west coast of Korea: a lateral headland bypass model for beach-dune formation

    2017-08-01

    The Dasari beach-dune system fronted by an intertidal mud flat is a typical example of numerous small beaches found both in embayments and along the open macrotidal west coast of Korea. The beach is frequently exposed to energetic wave action at high tide in winter. Although this coastal dune-sandy beach-intertidal mud flat system has previously been described, its origin and morphodynamic behavior has to date not been firmly established. To clarify these issues, elevation profiles and surficial sediment samples were collected seasonally along five monitoring transects across the tidal flat. In addition, box-cores as well as vibro- and drill-cores were acquired along the middle transect. Optically stimulated luminescence (OSL) and 14C- AMS (accelerator mass spectrometry) dating methods were applied to determine the age of the tidal flat, the beach and the dune deposits. The results show that Dasari beach is topographically composed of two distinct morphological and sedimentological sectors, comprising a high-tide sandy beach that merges seaward into an extensive low-tide tidal flat composed of mud. The transition between the two sectors is marked by a sharp break in slope and change in internal sedimentary structures. At the boundary, the subtle shoreward fining trend in mean grain size on the intertidal flat switches to a pronounced shoreward coarsening trend. Near the transition, mixing between the beach sand and the mud is observed. Another striking feature is a seasonal rotation of the beach system centered on the middle sector, with the northern sector eroding in winter and accreting in summer, and the southern sector accreting in winter and eroding in summer. The spatial grain-size pattern reveals that the beach is fed from the neighboring beach in the north by lateral headland bypassing, rather than onshore transport across the tidal flat, the intermittent lateral supply of sand explaining the seasonal rotation of the beach. Stratigraphically, the beach

    Beach volleyball is frequently used as a conditioning activity for indoor volleyball players, but little information exists regarding any performance benefits when transitioning from sand to hard court. The present study examined the effect of 12 weeks beach volleyball training on muscle performance of indoor volleyball players. Eleven athletes who completed an indoor volleyball season and were willing to train and compete at beach volleyball, participated in the study. Muscle endurance of knee extensors and plantar flexors (torque at 120°·s-1 following 40 contractions), muscle strength of knee extensors/ flexors (60, 180, 300°·s-1), dorsi/ plantar flexors (torque at 60, 120, 180°·s-1) trunk flexors (60, 90, 180°·s-1) and power (squat (SJ) and countermovement (CMJ) jumps performed on sand and hard court surfaces) were assessed pre- and post-12 weeks of beach volleyball training. Knee extensors and plantar flexors endurance was higher post-12 weeks, as less torque decrease was found after 40 contractions for both muscle groups at post-12 weeks time points. Knee extensors strength was higher post-12 weeks for 60 and 300°·s-1, while dorsi flexors strength was higher post-12 weeks for all speeds. SJ and CMJ vertical jump height was improved when measured on sand and on hard court. Twelve weeks of systematic training and competition at beach volleyball can improve muscular endurance of lower limbs and jumping height in indoor volleyball players. More importantly, these improvements are transferrable to hard court, making beach volleyball a very attractive alternative for conditioning indoor volleyball players during the off-indoor volleyball season.

    The BP MC252 well failure in the Gulf of Mexico, April 2010 caused concern for crude oil and polycyclic aromatic hydrocarbon (PAHs) exposure along the sandy beaches of the Florida Panhandle. We began collections of Coquina clams (Donax spp.) from the surf zone of Florida Panhandle beaches to monitor PAH contamination to compliment analysis of surf zone sand samples. These clams had higher levels of PAHs relative to ambient sand, and this allowed us to continue to monitor PAH levels after sand concentrations fell below limits of detection. PAH levels in the Coquina tissues were highly variable, perhaps indicative of the heterogeneous distribution of oil and tar on the beaches and exposure to tar particles. Overall, PAH levels decreased continuously in both sand and Coquina tissues, reaching limits of detection within one and two years respectively after oil landed on Florida Panhandle beaches. Our work suggests these surf zone molluscs may be used to monitor pollutant exposure along high energy sandy beach shorelines. Copyright © 2014 Elsevier Ltd. All rights reserved.

  14. Temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil

    Full Text Available The temporal variability of benthic macrofauna on Cassino beach, southernmost Brazil, was studied for a period of one year (June 2004 to May 2005 based on monthly sampling. Three sites were selected distant 50m from each other. At each site, 3 transects were established, 2m equidistant from one another. Each transect extended from the base of the primary dunes to the inner surf zone at approximately 1m in depth, with 7 or 8 sampling levels. Within transects, the distance between the levels was 20m until the upper swash zone, from which distance was 10m until the 1-meter isobath. The temporal variation in the abundance of benthic macrofauna observed in the present study can be attributed to (1 the positive effects of the recruitment peaks and migration of particular species to the swash zone and (2 negative effects of the migration of some species to deeper waters, as well (3 as mortality through natural causes (stranding and action of predators and (4 human causes (harvesting and vehicle transit. We attribute the expressive abundance increase of benthic macrofauna to recruitment. The stranding, that is, the trapping of the organisms on the upper parts of the beach, is likely the main cause of abrupt drops in benthic macrofauna abundance.

    This two year field monitoring project examines the response and recovery of a coastal beach-dune system in the west coast of Ireland (The Maharees, Co. Kerry) to storms. Historic analyses were completed using maps, aerial photography, and DGPS surveys with the Digital Shoreline Analysis System. The results establish that the average shoreline recession along the 1.2 km site is 72 m during the past 115 years. The coastal monitoring experiment aims to link micro-scale aeolian processes and meso-scale beach-dune behaviour to identify and quantify sediment exchange between the beach and dune under different meteorological and hydrodynamic conditions. Geomorphological changes on the beach and near-shore bar migration were monitored using repeated monthly DGPS surveys and drone technology. Topographical data were correlated with atmospheric data obtained from a locally installed Campbell Scientific automatic weather station, oceanographic data from secondary sources, and photogrammetry using a camera installed at the site collecting pictures every 10 minutes during daylight hours. Changes in surface elevation on the top of the foredune caused by aeolian processes are measured using erosion pin transects. The preliminary results illustrate that natural beach building processes initiate system recovery post storms including elevated foreshores and backshores and nearshore sand bar migration across the entire 1.2 km stretch of coastline. In parallel with the scientific work, the local community have mobilized and are working closely with the lead scientists to implement short term coastal management strategies such as signage, information booklets, sand trap fencing, walkways, wooden revetments, dune planting in order to support the end goal of obtaining financial support from government for a larger, long term coastal protection plan.

    Monitoring beach waters for human health has led to an increase and evolution of science in the Great Lakes, which includes microbiology, limnology, hydrology, meteorology, epidemiology, and metagenomics, among others. In recent years, concerns over the accuracy of water quality standards at protecting human health have led to a significant interest in understanding the risk associated with water contact in both freshwater and marine environments. Historically, surface waters have been monitored for fecal indicator bacteria (fecal coliforms, Escherichia coli, enterococci), but shortcomings of the analytical test (lengthy assay) have resulted in a re-focusing of scientific efforts to improve public health protection. Research has led to the discovery of widespread populations of fecal indicator bacteria present in natural habitats such as soils, beach sand, and stranded algae. Microbial source tracking has been used to identify the source of these bacteria and subsequently assess their impact on human health. As a result of many findings, attempts have been made to improve monitoring efficiency and efficacy with the use of empirical predictive models and molecular rapid tests. All along, beach managers have actively incorporated new findings into their monitoring programs. With the abundance of research conducted and information gained over the last 25 years, “Beach Science” has emerged, and the Great Lakes have been a focal point for much of the ground-breaking work. Here, we review the accumulated research on microbiological water quality of Great Lakes beaches and provide a historic context to the collaborative efforts that have advanced this emerging science.

    OBJECTIVE To examine how patient satisfaction with care coordination and quality and access to medical care influence functional improvement or deterioration (activity limitation stage transitions), institutionalization, or death among older adults. DESIGN A national representative sample with two year follow-up. SETTING Medicare Current Beneficiary Survey (MCBS) from calendar years 2001-2008. PARTICIPANTS Our study sample included 23,470 community-dwelling adults aged 65 years and older followed for two years. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE(S) A multinomial logistic regression model taking into account the complex survey design was used to examine the association between patient satisfaction with care coordination and quality and patient satisfaction with access to medical care and activity of daily living (ADL) stage transitions, institutionalization, or death after two years, adjusting for baseline socioeconomics and health-related characteristics. RESULTS Out of 23,470 Medicare beneficiaries, 14,979 (63.8% weighted) remained stable in ADL stage, 2,508 (10.7% weighted) improved, 3,210 (13.3% weighted) deteriorated, 582 (2.5% weighted) were institutionalized, and 2,281 (9.7% weighted) died. Beneficiaries who were in the top quartile of satisfaction with care coordination and quality were less likely to be institutionalized (adjusted relative risk ratio (RRR) = 0.68, 95% confidence interval (CI): 0.54-0.86). Beneficiaries who were in the top quartile of satisfaction with access to medical care were less likely to functionally deteriorate (adjusted RRR = 0.87, 95% CI: 0.79-0.97), be institutionalized (adjusted RRR = 0.72, 95% CI: 0.56-0.92), or die (adjusted RRR = 0.86, 95% CI: 0.75-0.98). CONCLUSIONS Knowledge of patient satisfaction with medical care and risk of functional deterioration may be helpful for monitoring and addressing disability-related healthcare disparities and the impact of ongoing policy changes among Medicare beneficiaries

    Marine litter and its accumulation on beaches is an issue of major current concern due to its significant environmental and economic impacts. Yet our understanding of spatio-temporal trends in beach litter and the drivers of these trends are currently limited by the availability of robust long term data sets. Here we present a unique data set collected systematically once a month, every month over a six year period for nine beaches along the North Coast of Cornwall, U.K. to investigate the key drivers of beach litter in the Bude, Padstow and Porthcothan areas. Overall, an average of 0.02 litter items m -2 per month were collected during the six year study, with Bude beaches (Summerleaze, Crooklets and Widemouth) the most impacted (0.03 ± 0.004 litter items m -2 per month). The amount of litter collected each month decreased by 18% and 71% respectively for Padstow (Polzeath, Trevone and Harlyn) and Bude areas over the 6 years, possibly related to the regular cleaning, however litter increased by 120% despite this monthly cleaning effort on the Padstow area beaches. Importantly, at all nine beaches the litter was dominated by small, fragmented plastic pieces and rope fibres, which account for 32% and 17% of all litter items collected, respectively. The weathered nature of these plastics indicates they have been in the marine environment for an extended period of time. So, whilst classifying the original source of these plastics is not possible, it can be concluded they are not the result of recent public littering. This data highlights both the extent of the marine litter problem and that current efforts to reduce littering by beach users will only tackle a fraction of this litter. Such information is vital for developing effective management strategies for beach and marine litter at both regional and global levels. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2014-01-01

    Field topographic surveys were conducted at intervals of months from 2004 to 2006 in order to highlight the sediment circulation patterns of the embayed beach of Essaouira, on the Atlantic coast of Morocco, especially under the influence of a nearby wadi, the Ksob, which is the main sediment purveyor of the beach, notably via flash floods. The profile data highlight longshore and cross-shore variations in beach morphology. Constant winds from the north rework the upper beach to form barchans ...

    Oil-pollution monitoring at sea through beach bird surveying would undoubtedly benefit from a further standardisation of methods, enhancing the efficiency of data collection. In order to come up with useful recommendations, we evaluated various approaches of beached bird collection at the Belgian coast during seven winters (1993-1999). Data received in a passive way by one major rehabilitation centre were compared to the results of targeted beach surveys carried out at different scales by trained ornithologists: 'weekly' surveys - with a mean interval of 9 days - restricted to a fixed 16.7 km beach stretch, 'monthly' surveys over the entire coastline (62.1 km) and an annual 'international' survey in Belgium over the same distance at the end of February. Data collected through Belgian rehabilitation centres concern injured, living birds collected in a non-systematical way. Oil rates derived from these centres appear to be strongly biased to oiled auks and inshore bird species, and are hence of little use in assessing the extent of oil pollution at sea. The major asset of rehabilitation centres in terms of data collection seems to be their continuous warning function for events of mass mortality. Weekly surveys on a representative and large enough section rendered reliable data on oil rates, estimates of total number of bird victims, representation of various taxonomic groups and species-richness and were most sensitive in detecting events quickly (wrecks, oil-slicks, severe winter mortality, etc.). Monthly surveys gave comparable results, although they overlooked some important beaching events and demonstrated slightly higher oil rates, probably due to the higher chance to miss short-lasting wrecks of auks. Since the monthly surveys in Belgium were carried out by a network of volunteers and were spread over a larger beach section, they should be considered as best performing. Single 'international beached bird surveys' in February gave reliable data on total victim

    Observations and measurements of petroleum tar balls on a number of Kenyan beaches were carried out between 1979 and 1982. A large variation in the size and amount of tar deposit at the beaches was recorded. These values ranged from very small pebbles to large lumps of 30 cm in diameter, weighing up to 1.5 kg. The average tar loading during the sampling period ranged from 0-18 g/m2. Between 25-50% by weight of the tar lumps were shell fragments, sand and other nonpetroleum debris. The chemica...

    Sandy beaches are central economic assets, attracting more recreational users than other coastal ecosystems. However, urbanization and landscape modification can compromise both the functional integrity and the attractiveness of beach ecosystems. Our study aimed at investigating the relationship between sandy beach artificialization and the landscape perception by the users, and between sandy beach visual attractiveness and biodiversity. We conducted visual and biodiversity assessments of urbanized and semiurbanized sandy beaches in Brazil and Uruguay. We specifically examined meiofauna as an indicator of biodiversity. We hypothesized that urbanization of sandy beaches results in a higher number of landscape detractors that negatively affect user evaluation, and that lower-rated beach units support lower levels of biodiversity. We found that urbanized beach units were rated lower than semiurbanized units, indicating that visual quality was sensitive to human interventions. Our expectations regarding the relationship between landscape perception and biodiversity were only partially met; only few structural and functional descriptors of meiofauna assemblages differed among classes of visual quality. However, lower-rated beach units exhibited signs of lower environmental quality, indicated by higher oligochaete densities and significant differences in meiofauna structure. We conclude that managing sandy beaches needs to advance beyond assessment of aesthetic parameters to also include the structure and function of beach ecosystems. Use of such supporting tools for managing sandy beaches is particularly important in view of sea level rise and increasing coastal development.

    2014-07-01

    Beach is an important coastal protective barrier and tourism resources. Beach environment monitoring can help beach managers to make feasible decisions. Digital image of video monitoring technology can provide high resolution information of temporal and spatial variation of near shore in real time. The application of Video monitoring technology has been implemented in Qingdao's Shilaoren beach. The clustering method based on Gaussian mixture model is applied to extract beach enteromorpha changs for the digital images. Analysis results show that, the period of enteromorpha in Qingdao's Shilaoren beach was mainly from the early July to the mid-August in 2011, and the decline of enteromorpha is mainly associated with the rising temperature in the mid-August. Storm has significant impact on the beach enteromorpha. Tourists' activity space on the beach will decrease due to the enteromorpha covering on the beach, which affects beach tourism activities. Therefore, it's necessary to make preventive measures to avoid enteromorpha piling up on the beach, which is of great importance to the bathing beach environment and tourism development.

    2007-11-01

    The stability of living situation was examined as a predictor of young people's HIV-related sexual and drug use acts two years after leaving home for the first time. Newly homeless youth aged 12-20 years were recruited in Los Angeles County, California, U.S.A. (n = 261) and Melbourne, Australia (n = 165) and followed longitudinally at 3, 6, 12, 18, and 24 months. Their family history of moves and the type and frequency of moves over the two years following becoming newly homeless were examined. Regression analyses indicated that recent sexual risk two years after becoming newly homeless was not related to the instability of youths' living situations; condom use was higher among youth with more placements in institutional settings and among males. Drug use was significantly related to having moved more often over two years and Melbourne youth used drugs significantly more than youth in Los Angeles.

    This study compares tobacco use rates among two-year and four-year college students and explores the demographic variables that predicted that behavior. 9,931 students at 14 two-year and four-year colleges in Minnesota participated. Students at 11 schools completed an online survey, and students at 3 schools completed a paper survey in 2007. After controlling for sex, age, ethnicity, relationship status, hours of work per week, and number of school credits, attending a two-year college predicted current and daily smoking (odds ratio [OR]) = 1.70, 95% confidence interval [CI] = 1.52-1.89; OR = 3.47, 95% CI = 2.94-4.11) and smokeless tobacco use (OR = 1.65, 95% CI = 1.32-2.06; OR = 1.64, 95% CI = 1.06-2.53). Although two-year college students comprise approximately two fifths of the college student population, surveys of college student tobacco use have focused nearly exclusively on four-year college students. Two-year college students should represent a priority population for tobacco control because attending a two-year college predicts increased tobacco use.

    Actions taken to prevent or reduce coastal erosion often do not have the desired effect, leading to major problems instead of solving the original one. This research focuses on why a nourished beach- with borrowed sand and 0.05% of particles beach users as turbidity. This means that the colour of the water was not its characteristic blue, even with calm wave conditions. This research involved a shoreline evolution analysis and a sedimentological study of the sand from 1977 to 2017. The results show that the turbidity episodes that occurred after the beach fill of May 2017 do not coincide with major storms that affected the beach. Furthermore, prior to this beach nourishment, even after the most important storms turbidity was not so pronounced. However, when the pre-nourishment and post-nourishment sediment are compared and analysed in detail, by studying the microstructure and morphology of the sand particles, their composition and morphology were observed to be completely different. These differences are also reflected in the accelerated particle weathering test, with the post-nourishment particles showing greater dissolution of carbonates. From its mineralogy, the post-nourishment material presents a smaller proportion of quartz in its composition and a significant amount of particles (9.6%) formed by clusters of Calcium and Silicon. The separation of this mineralogical composition produced by waves explains the formation of particles measuring beach. Copyright © 2018 Elsevier B.V. All rights reserved.

  15. Trophic niche shifts driven by phytoplankton in sandy beach ecosystems

    Stable isotopes (δ13C and δ15N) together with chlorophyll a and densities of surf diatoms were used to analyze changes in trophic niches of species in two sandy beaches of Uruguay with contrasting morphodynamics (i.e. dissipative vs. reflective). Consumers and food sources were collected over four seasons, including sediment organic matter (SOM), suspended particulate organic matter (POM) and the surf zone diatom Asterionellopsis guyunusae. Circular statistics and a Bayesian isotope mixing model were used to quantify food web differences between beaches. Consumers changed their trophic niche between beaches in the same direction of the food web space towards higher reliance on surf diatoms in the dissipative beach. Mixing models indicated that A. guyunusae was the primary nutrition source for suspension feeders in the dissipative beach, explaining their change in dietary niche compared to the reflective beach where the proportional contribution of surf diatoms was low. The high C/N ratios in A. guyunusae indicated its high nutritional value and N content, and may help to explain the high assimilation by suspension feeders at the dissipative beach. Furthermore, density of A. guyunusae was higher in the dissipative than in the reflective beach, and cell density was positively correlated with chlorophyll a only in the dissipative beach. Therefore, surf diatoms are important drivers in the dynamics of sandy beach food webs, determining the trophic niche space and productivity. Our study provides valuable insights on shifting foraging behavior by beach fauna in response to changes in resource availability.

    When beach water monitoring programs identify poor water quality, the causes are frequently unknown. We hypothesize that management policies play an important role in the frequency of fecal indicator bacteria (FIB) exceedances (enterococci and fecal coliform) at recreational beaches. To test this hypothesis we implemented an innovative approach utilizing large amounts of monitoring data (n > 150,000 measurements per FIB) to determine associations between the frequency of contaminant exceedances and beach management practices. The large FIB database was augmented with results from a survey designed to assess management policies for 316 beaches throughout the state of Florida. The FIB and survey data were analyzed using t-tests, ANOVA, factor analysis, and linear regression. Results show that beach geomorphology (beach type) was highly associated with exceedance of regulatory standards. Low enterococci exceedances were associated with open coast beaches (n = 211) that have sparse human densities, no homeless populations, low densities of dogs and birds, bird management policies, low densities of seaweed, beach renourishment, charge access fees, employ lifeguards, without nearby marinas, and those that manage storm water. Factor analysis and a linear regression confirmed beach type as the predominant factor with secondary influences from grooming activities (including seaweed densities and beach renourishment) and beach access (including charging fees, employing lifeguards, and without nearby marinas). Our results were observable primarily because of the very large public FIB database available for analyses; similar approaches can be adopted at other beaches. The findings of this research have important policy implications because the selected beach management practices that were associated with low levels of FIB can be implemented in other parts of the US and around the world to improve recreational beach water quality.

    1988-01-01

    A cumulative method is shown of graphical presentation of the twenty two-year periodicity of solar activity which allows to see the twenty two-year waves of solar activity as basic elements of a cumulative curve of yearly means of observed relative numbers. The ascending branch of each wave represents the successively summed yearly means belonging to the even eleven-year cycles while the descending branch represents yearly means successively subtracted from such a value belonging to the odd eleven-year cycles. In this way the mutual relations were investigated of the individual eleven-year cycles forming one twenty two-year cycle as well as the secular changes in these relations due to the variability of the power of the individual eleven-year cycles and consequent variations of the general secular trends in solar activity development. Also discussed were the length of the periods of secular activity changes using the method of the correlation periodogram. The fine structure was also shown of the main twenty two-year period and the same twenty two-year waves in other indices of solar activity were searched for. (author). 1 figs., 2 tabs., 19 refs

    Full Text Available Cross-shore profiles and environmental forcing were used to analyse morphological change of a headland bay beach: Tenby, West Wales (51.66 N; −4.71 W over a mesoscale timeframe (1996–2013. Beach profile variations were attuned with longer term shoreline change identified by previous research showing southern erosion and northern accretion within the subaerial zone and were statistically significant in both sectors although centrally there was little or no significance. Conversely a statistically significant volume loss was shown at all profile locations within the intertidal zone. There were negative phase relationships between volume changes at the beach extremities, indicative of beach rotation and results were statistically significant (p < 0.01 within both subaerial (R2 = 0.59 and intertidal (R2 = 0.70 zones. This was confirmed qualitatively by time-series analysis and further cross correlation analysis showed trend reversal time-lagged associations between sediment exchanges at either end of the beach. Wave height and storm events displayed summer/winter trends which explained longer term one directional rotation at this location. In line with previous regional research, environmental forcing suggests that imposed changes are influenced by variations in southwesterly wind regimes. Winter storms are generated by Atlantic southwesterly winds and cause a south toward north sediment exchange, while southeasterly conditions that cause a trend reversal are generally limited to the summer period when waves are less energetic. Natural and man-made embayed beaches are a common coastal feature and many experience shoreline changes, jeopardising protective and recreational beach functions. In order to facilitate effective and sustainable coastal zone management strategies, an understanding of the morphological variability of these systems is needed. Therefore, this macrotidal research dealing with rotational processes across the entire intertidal

    This article provides an evaluation of the first two years of implementation of a statewide nursing consortium (SNC) curriculum on nursing faculty work life, teaching productivity, and quality of education. In response to the call for nursing education reform, the SNC incorporated new approaches to competency-based, student-centered learning and clinical education. Faculty and two cohorts of students were measured at three points over the first two years of the curriculum implementation. The expected positive impact of the SNC was documented at the start of the first year, but not sustained. Students reported having more confidence in their clinical skills at the start of the first year, yet demonstrated significantly less confidence in their ability after two years. Faculty indicated that the SNC allowed greater opportunity for collaboration, but that the experience did not alter their classroom performance or satisfaction beyond the first year.

    During military service young men (age 19-21 years) are exposed to many predisposing factors for asthma. We aimed to study the short-term prognosis of asthma after the military service. All 216 men with verified asthma in 2004-2005 from the register of the Central Military Hospital were included in the study. A questionnaire was mailed to them in autumn 2007 and the 146 responders (68%) formed the final study population. Asthma severity was evaluated during military service according to the medical records of the subjects and two years later based on the questionnaire using modified GINA guidelines. The results on lung function and allergy tests during military service and asthma history were used as predictors of asthma severity at two-year follow-up. Two groups of asthmatics were identified: those who already had asthma when entering the military service (n=71, 48.6%) and those, who had a new onset of asthma during the service (n=75, 51.4%). Overall asthma was less severe at two-year follow-up than during military service (p=0.036). Both during military service and at two-year follow-up, asthma was milder among the men, who had a new onset of asthma during military service. Atopy (p=0.002), number of positive skin-prick tests (p=0.005) and higher total serum IgE (p=0.001) were significant predictors for persistent asthma at follow-up. Asthma, which had aggravated or started during military service, was significantly less severe two years later. The degree of atopy was a major determinant of the two-year prognosis of asthma after military service.

    In order to monitor malnutrition morbidity and anaemic prevalence of infants and young children in rural disaster areas affected by Wenchuan earthquake. About three months, one year and two years after earthquake (including 77, 102 and 307 children, respectively), by using the questionnaires, information on nutritional and health status of infants and young children aged 6-23 months was collected and evaluated, and anthropometry and haemoglobin concentration were measured. Most of families could not prepare complementary foods for their children so that the children only ate the same meals as adults which resulted in very poor situation in the quantity and quality of complementary food for infants and young children. The main nutritional problems in children included the lack of feeding knowledge in parents; only 10% children could have breast feeding within one hour after delivery, and the basic exclusive breastfeeding was lower. More than 90% children never received nutrient supplements. The malnutrition prevalence was significantly increased two years after the earthquake. The decrease of body weight was rapid (underweight prevalence from 0 at three months to 5.9% after two years), and then a lasting effect resulted in decrease of length shown by stunting prevalence from 6.6% at three months to 10.8% after two years and wasting prevalence from 1.3% at three months to 4.0% after two years. From three months to two years after earthquake, anaemic prevalence markedly increased from 36.5% to 67.5% and the increasing percentage of anaemia was more obvious in girls than boys. The child's nutritional status continuously worsened and anaemic prevalence was high in areas affected by the earthquake. It is recommended that in the future nutrition interventions should begin immediately.

However, most of these problems were resolved after two years, and there was no evidence of the concentration camp syndrome, homicidal or suicidal behavior, violent physical aggression, impotence, fugue states, psychosomatic disorders, or major psychiatric illnesses in any of the men. On the basis of their findings, the authors make recommendations for future reentry programs.

    Coastal zones are among the most active areas on Earth, being subjected to extreme wind / wave conditions, thus vulnerable to erosion. In Greece and Crete in particular, beach zones are extremely important for the welfare of the inhabitants, since, apart for the important biological and archaeological value of the beach zones, the socio-economic value is critical since a great number of human activities are concentrated in such areas (touristic facilities, fishing harbors etc.). The present study investigates the erosional procedures observed in Plaka beach, E. Crete, Greece, a highly touristic developed area with great archaeological interest and proposes a cost-effective solution. The factors taken into consideration for the proposed solution in reducing the erosion of the beach were the study of the climatological, geological and geomorphological regime of the area, the recent (~70 years) shifting of the coastline through the study of topographic maps, aerial photographs and satellite images, the creation of detailed bathymetric and seabed classification maps of the area and finally, a risk analysis in terms of erosional phenomena. On the basis of the above, it is concluded that the area under investigation is subjected to an erosional rate of about 1 m/10 years and the total land-loss for the past 70 years is about 4600 m2. Through the simulation of the wave regime we studied 3 possible scenarios, the "do-nothing" scenario, the construction of a detached submerged breakwater at the depth of 3 meters and, finally, the armoring of the existing beach-wall through the placement of appropriate size and material boulders, forming an artificial slope for the reducing of the wave breaking energy and a small scale nourishment plan. As a result, through the modeling of the above, the most appropriate and cost-effective solution was found to be the third, armoring of the existing coastal wall and nourishment of the beach periodically, thus the further undermining of the

    2009-03-01

    Knowledge of the marine soils properties, together with hydrodynamic and climatic data, plays an important role for a better understanding of the dynamic behavior of sandy and muddy coasts. This paper deals with reporting and basic interpretation of two campaigns of exploration and characterization of the mud of Cassino Beach, southern Brazil, carried out during the years of 2004 and 2005. Samples were obtained by means of cores collected at some locations offshore, and were submitted to various laboratory geotechnical tests, including determination of the physical index, grain size distribution, Atterberg limits, and shear resistance by both triaxial and shear vane tests. Results confirm the existence of a very soft soil deposit offshore Cassino Beach, highly plastic, compressible, and viscous, forming an important database for further studies.

  7. Beach sand minerals in ceramic applications

    2004-01-01

    Ceramics are in use since the time memorial and many new materials belonging to this segment of industry have come to existence as the human civilization progressed. Although clay and some non-clay minerals are used in the traditional ceramics, they are not compatible for advanced ceramic applications. The synthesized compounds of elements like aluminium, silicon, titanium, zirconium, rare earths etc are having ability to satisfy the requirements of such advanced high tech applications. The six heavy minerals present in abundantly available Indian beach sand minerals happen to contain these elements and find application as such or in their value added forms both in traditional and advanced ceramics. In this paper an effort has been made to describe the role of beach sand minerals being produced by Indian Rare Earths Ltd as basic raw materials for the Indian ceramic industry. (author)

Neuropraxia of the great auricular nerve (GAN is an uncommon complication of shoulder surgery, with the patient in the beach chair position. We report a case of great auricular neuropraxia associated with direct compression by a horseshoe headrest, used in routine positioning for uncomplicated shoulder surgery. In this case, an arthroscopic approach was taken, under regional anesthesia with sedation in the beach chair position. The GAN, a superficial branch of the cervical plexus, is vulnerable to neuropraxia due to its superficial anatomical location. We recommend that for the procedures of the beach chair position, the auricle be protected and covered with cotton and gauze to avoid direct compression and the position of the head and neck be checked and corrected frequently. Keywords: neuropraxia, anesthesia, arthroscopy, great auricular nerve

  10. Internal wave turbulence near a Texel beach.

    Directory of Open Access Journals (Sweden)

    Hans van Haren

    Full Text Available A summer bather entering a calm sea from the beach may sense alternating warm and cold water. This can be felt when moving forward into the sea ('vertically homogeneous' and 'horizontally different', but also when standing still between one's feet and body ('vertically different'. On a calm summer-day, an array of high-precision sensors has measured fast temperature-changes up to 1 °C near a Texel-island (NL beach. The measurements show that sensed variations are in fact internal waves, fronts and turbulence, supported in part by vertical stable stratification in density (temperature. Such motions are common in the deep ocean, but generally not in shallow seas where turbulent mixing is expected strong enough to homogenize. The internal beach-waves have amplitudes ten-times larger than those of the small surface wind waves. Quantifying their turbulent mixing gives diffusivity estimates of 10(-4-10(-3 m(2 s(-1, which are larger than found in open-ocean but smaller than wave breaking above deep sloping topography.

    To analyze whether the information found on popular Internet sites are in accordance with the steps recommended by the Food Guide for Children Younger than Two Years of the Ministry of Health (2010). Descriptive/comparative study, carried out between August and October 2014, which carried out a search for popular sites (for lay people) in Portuguese, containing information on nutrition of children younger than two years. The Google search engine was used. These findings were compared with the Food Guide for Children Younger than Two Years of the Ministry of Health (2010). It was verified whether the information shown on the websites was in accordance with the Guide. A total of 50 sites were analyzed, including blogs, food company websites and websites specialized in child nutrition. Only 10% of those pages correctly showed every step of the Food Guide. The recommendations were: exclusive breastfeeding up to six months of life (80%); complementary feeding from six months of life (36%); baby food consistency according to the guide (48%); encouraging the consumption of fruits and vegetables daily (60%). Regarding the complementary feeding safety and hygiene, 26% contained correct information. Only 36% correctly warned about which foods should be avoided in the first years of life. The information found on the sites is largely in disagreement with the Ministry of Health recommendations, which can lead to misconceptions in the nutritional care of the children younger than two years.

    2010-01-01

    This study evaluated the clinical performance of a nanohybrid and a low shrinkage posterior composite in Class I and II restorations after two years. A total of 82 Class I and Class II cavities were restored in 31 patients (10 male, 21 female) by one clinician using Grandio and Quixfil and the manufacturers' self-etch adhesives (Futura Bond and Xeno III) according to the manufacturers' instructions. Two previously calibrated operators clinically evaluated the restorations one week after placement (baseline) and six months, one year and two years after placement using modified USPHS criteria. Statistical analysis was completed using the Pearson Chi-square and Fisher's Exact Test (p0.05). None of the restorations had shown any marginal discoloration and anatomic form loss until the end of the 12-month period. Two-year recall data demonstrated an 83.87% recall rate (26 patients). Grandio restorations showed a significant deterioration of the surface properties that demonstrated 26% Bravo scores, which are still clinically acceptable. None of the restorations exhibited postoperative sensitivity at any evaluation period. It was concluded that nanofill (Grandio) and posterior composite (Quixfil) demonstrated acceptable clinical performance after two years. However, further evaluations are necessary for the long-term clinical performance of these materials.

    With the increasing use of anti-TNF therapy in inflammatory bowel disease (IBD), a shift of costs has been observed with medication costs replacing hospitalization and surgery as major cost driver. We aimed to explore the evolution of IBD-related costs over two years of follow-up. In total 1,307 Crohn's disease (CD) patients and 915 ulcerative colitis (UC) patients were prospectively followed for two years by three-monthly web-based questionnaires. Changes of healthcare costs, productivity costs and out-of-pocket costs over time were assessed using mixed model analysis. Multivariable logistic regression analysis was used to identify costs drivers. In total 737 CD patients and 566 UC were included. Total costs were stable over two years of follow-up, with annual total costs of €7,835 in CD and €3,600 in UC. However, within healthcare costs, the proportion of anti-TNF therapy-related costs increased from 64% to 72% in CD (pyears in UC (adj. OR 4.72 (95% CI 1.61-13.86)). BD-related costs remained stable over two years. However, the proportion of anti-TNF-related healthcare costs increased, while hospitalization costs decreased. Factors associated with increased costs were penetrating disease course in CD and age <40 in UC.

    Full Text Available Introduction: In the treatment of portal hypertension in pediatric patients, some type of porto-systemic shunt is indicated, which is an unusual surgical procedure in patients under two years of age, due to the low incidence of this disease at this age and the increase in the number of complications. Objective: We present our experience and results with this procedure in patients under two years of age seen in the Hepatobiliopancreatic general surgery service at Instituto Nacional de PediatríaDiscussion: The causes of portal hypertension in children are varied. Among the extrahepatic causes, the most common is cavernomatous portal degeneration. Children with portal hypertension under two years have severe symptoms such as recurrent gastrointestinal bleeding or anemia; others have hypersplenism data. In many cases medical management is useless and a surgical procedure require such as a portosystemic shunt in order to decrease the size of varicose esophageal veins and prevent bleeding that threatens the patient’s life. Conclusion: The iliac-mesenteric-caval shunt in patients under two years is a feasible alternative that improves the clinical status of the patient, reducing the risk of bleeding. However long-term studies are needed to determine the outcome of these patients. Keywords: Iliac-mesenteric-caval shunt, portal hypertension.

    Building a strong and diverse geoscience workforce is a critical national challenge. Two-year colleges (2YCs) play an important role in increasing both the number and diversity of geoscience graduates. A workshop on Preparing Students from Two-year Colleges for Geoscience Degrees and Careers was held in Tacoma, WA in July 2012 to discuss the successes and challenges of programs, strategies, and activities that support career preparation of 2YC students for geoscience careers, either as geotechnical graduates or as geoscience majors at four-year colleges and universities, and to make recommendations for future efforts. At the workshop several successful partnerships between employers and two-year colleges as well as between two-year colleges and four-year institutions were discussed as potential models that could be replicated with adaptations for local employment needs. Participants shared successful techniques for supporting 2YC students in their career path such as internships, early opportunities for participating in research, joint fieldtrips with transfer institutions, and supportive curriculum alignment between two and four-year institutions. Professional organizations have much to offer including information about career options, networking opportunities, and more. Participants discussed strategies for supporting geoscience workforce development at 2YCs such as making connections between 2YCs and local employers, identifying geoscience students at 2YCs who are planning to transfer and building relationships with 4YCs, establishing internship programs, supporting student geoscience clubs, and developing a repository of geoscience employment information targeted to 2YC students. Participants recognized significant barriers to incorporating career training and information into the geoscience curriculum at two-year colleges. These barriers include a predominance of non-geoscience students in classes, lack of support or rewards for improving or increasing the

    Diabetes has been associated with poor outcomes following elective spine surgery. The purpose of our study was to determine if diabetes predicts worse patient-reported outcomes at two years postoperatively and to evaluate the effect of perioperative blood glucose levels and control on patient-reported outcomes in patients with diabetes. One thousand and five patients undergoing elective spine surgery were included in this prospective cohort study. The presence of diabetes and baseline and one and two-year patient-reported outcomes (Short Form-12 [SF-12], EuroQol-5D [EQ-5D], Oswestry Disability Index [ODI] or Neck Disability Index [NDI], and Numeric Rating Scale [NRS] pain scores) were recorded. The mean blood glucose measurements in patients with diabetes were collected during the postoperative period. Multivariable linear regression analyses were performed to determine predictors of one and two-year outcomes as well as the relationship between perioperative blood glucose and patient-reported outcomes in patients with diabetes. Four hundred and thirty-four patients (43%) had diabetes. When compared with patients without diabetes at two years, patients with diabetes had lower SF-12 Physical Component Summary scores (34.4 points for the diabetic group compared with 38.6 points for the non-diabetic group), lower EQ-5D scores (0.67 for the diabetic group compared with 0.74 for the non-diabetic group), higher ODI or NDI scores (32.1 points for the diabetic group compared with 26.8 points for the non-diabetic group), and higher NRS scores (5.1 points for the diabetic group compared with 4.3 points for the non-diabetic group) (p two years. Perioperative blood glucose control did not predict outcomes at either one or two years in patients with diabetes. Diabetes was associated with worse patient-reported outcomes when patients with diabetes were compared with patients without diabetes at two years following elective spine surgery. Although patients with diabetes improved

    Large databases of fecal indicator bacteria (FIB) measurements are available for coastal waters. With the assistance of satellite imagery, we illustrated the power of assessing data for many sites by evaluating beach features such as geomorphology, distance from rivers and canals, presence of piers and causeways, and degree of urbanization coupled with the enterococci FIB database for the state of Florida. We found that beach geomorphology was the primary characteristic associated with enterococci levels that exceeded regulatory guidelines. Beaches in close proximity to marshes or within bays had higher enterococci exceedances in comparison to open coast beaches. For open coast beaches, greater enterococci exceedances were associated with nearby rivers and higher levels of urbanization. Piers and causeways had a minimal contribution, as their effect was often overwhelmed by beach geomorphology. Results can be used to understand the potential causes of elevated enterococci levels and to promote public health. Copyright © 2017 Elsevier Ltd. All rights reserved.

  16. Recreational impacts on Colorado River beaches in Glen Canyon, Arizona

    Carothers, Steven W.; Johnson, Robert A.; Dolan, Robert

    1984-07-01

    Recreational impact was measured on eight beaches in Glen Canyon National Recreation Area and 15 beaches in Grand Canyon National Park using permanently located transects and plots. Recreational impact indices included densities of human trash and charcoal and a measure of sand discoloration due to charcoal. Significant increases in the indices occurred on several Glen Canyon beaches over a seven-month period. Sand discoloration became significantly higher over all Glen Canyon beaches during the same time period. All indices were significantly higher in Glen Canyon than on similar Grand Canyon beaches. These differences are probably due to differences in: (a) level of impacts tolerated by the respective management regimes and, (b) in the number of user days among the two National Park Service administrative units. Management alternatives are presented for reversing the present trends of recreational impact on Glen Canyon beaches.

    Reduced leukocyte telomere length (LTL) has been found to be associated with multiple common age-related diseases, including heart disease, diabetes, and cancer. A link has also been suggested between shortened LTL and major depressive disorder (MDD), suggesting that MDD may be a disease of accelerated aging. This prospective, longitudinal study examined the association between depression diagnosis at baseline and change in LTL over two years in a well-characterized sample of N = 117 adults with or without MDD at baseline, using rigorous entry criteria. Participants aged 18-70 were assessed with validated instruments by trained, doctoral-level clinician raters at baseline and at two-year follow-up, and blood samples were obtained at both visits. LTL was assayed under identical methods using quantitative polymerase chain reaction (qPCR). The effect of an MDD diagnosis at baseline on change in LTL over two years was examined via hierarchical mixed models, which included potential confounders. Individuals with MDD at baseline had greater LTL shortening over two years than individuals without MDD (p = 0.03), even after controlling for differences in age, sex, and body mass index (BMI). In the sub-sample of individuals with MDD diagnoses at baseline, no significant associations between LTL change and symptom severity or duration were found. A baseline diagnosis of MDD prospectively predicted LTL shortening over two years. Our results provide further support for MDD as a disease associated with accelerated aging in a well-characterized sample using validated, clinician-rated measures. Copyright © 2018 Elsevier Ltd.

  18. Shifts in the microbial community composition of Gulf Coast beaches following beach oiling.

    Directory of Open Access Journals (Sweden)

    Ryan J Newton

    Full Text Available Microorganisms associated with coastal sands serve as a natural biofilter, providing essential nutrient recycling in nearshore environments and acting to maintain coastal ecosystem health. Anthropogenic stressors often impact these ecosystems, but little is known about whether these disturbances can be identified through microbial community change. The blowout of the Macondo Prospect reservoir on April 20, 2010, which released oil hydrocarbons into the Gulf of Mexico, presented an opportunity to examine whether microbial community composition might provide a sensitive measure of ecosystem disturbance. Samples were collected on four occasions, beginning in mid-June, during initial beach oiling, until mid-November from surface sand and surf zone waters at seven beaches stretching from Bay St. Louis, MS to St. George Island, FL USA. Oil hydrocarbon measurements and NOAA shoreline assessments indicated little to no impact on the two most eastern beaches (controls. Sequence comparisons of bacterial ribosomal RNA gene hypervariable regions isolated from beach sands located to the east and west of Mobile Bay in Alabama demonstrated that regional drivers account for markedly different bacterial communities. Individual beaches had unique community signatures that persisted over time and exhibited spatial relationships, where community similarity decreased as horizontal distance between samples increased from one to hundreds of meters. In contrast, sequence analyses detected larger temporal and less spatial variation among the water samples. Superimposed upon these beach community distance and time relationships, was increased variability in bacterial community composition from oil hydrocarbon contaminated sands. The increased variability was observed among the core, resident, and transient community members, indicating the occurrence of community-wide impacts rather than solely an overprinting of oil hydrocarbon-degrading bacteria onto otherwise

    Full Text Available This working paper focuses in enjoyment factors, specifically: number of beach users, perceived maximum number of beach users accepted, perceived maximum number of beach users that affects the tourism experience and perceived maximum number of beach users that affects the beach quality. At a deeper extent, the evaluation is categorized by number of visitation, visitation motivations, and Chenang Island’s push and pull factors. Relationships between variables were assessed using a two-phase evaluation framework where interestingly, only one demographic factor works with all the studied independent variables. It is also learned that the density of an area number of people seen is considered as a n accepted crowding factor, as opposed to this working paper scope experienced crowding . A unique relationship was observed for crowding level, and visitation satisfaction level and overall evaluation of Chenang beach quality. This working paper further supports the previous literature on the significance of beach carrying capacity management and it is learned that the idea of crowding standard is interlinks with ‘gender, ‘time spend’ and ‘number of boaters’. From findings, this working paper envisages the preferences polar exchange where this should be of interest to tourism-related personnel. It is within this working paper interest to highlight the pressing need in brandishing the image of Chenang Beach. This is to ensure that Chenang Beach, as a field, is maintaining its importance and popularity.

    2017-06-01

    Coastal visits not only provide psychological benefits but can also contribute to the accumulation of rubbish. Volunteer beach cleans help address this issue, but may only have limited, local impact. Consequently, it is important to study any broader benefits associated with beach cleans. This article examines the well-being and educational value of beach cleans, as well as their impacts on individuals' behavioral intentions. We conducted an experimental study that allocated students ( n = 90) to a beach cleaning, rock pooling, or walking activity. All three coastal activities were associated with positive mood and pro-environmental intentions. Beach cleaning and rock pooling were associated with higher marine awareness. The unique impacts of beach cleaning were that they were rated as most meaningful but linked to lower restorativeness ratings of the environment compared with the other activities. This research highlights the interplay between environment and activities, raising questions for future research on the complexities of person-environment interactions.

    More than two year of data from ESA's Swarm constellation mission are used to derive a model of the Earth’s magnetic field and its time variation (secular variation). The model describes contributions from the core and lithosphere as well as large-scale contributions from the magnetosphere (and its...... Earth-induced counterpart). We use data from geomagnetic quiet times and co-estimate the Euler angles describing the rotation between the vector magnetometer instrument frame and the North-East-Center (NEC) frame. In addition to the magnetic field observations provided by each of the three Swarm...... satellites and alongtrack first differences we include the East-west magnetic gradient information provided by the lower Swarm satellite pair, thereby explicitly taking advantage of the constellation aspect of Swarm. We assess the spatial and temporal model resolution that can be obtained from two years...

    Background Sacroiliac joint pain is a common cause of chronic low back pain. Different techniques for radiofrequency denervation of the sacroiliac joint have been used to treat this condition. However, results have been inconsistent because the variable sensory supply to the sacroiliac joint is difficult to disrupt completely using conventional radiofrequency. Cooled radiofrequency is a novel technique that uses internally cooled radiofrequency probes to enlarge lesion size, thereby increasing the chance of completely denervating the sacroiliac joint. The objective of this study was to evaluate the efficacy of cooled radiofrequency denervation using the SInergy™ cooled radiofrequency system for sacroiliac joint pain. Methods The charts of 20 patients with chronic sacroiliac joint pain who had undergone denervation using the SInergy™ cooled radiofrequency system were reviewed at two years following the procedure. Outcome measures included the Numeric Rating Scale for pain intensity, Patient Global Impression of Change, and Global Perceived Effect for patient satisfaction. Results Fifteen of 20 patients showed a significant reduction in pain (a decrease of at least three points on the Numeric Rating Scale). Mean Numeric Rating Scale for pain decreased from 7.4 ± 1.4 to 3.1 ± 2.5, mean Patient Global Impression of Change was “improved” (1.4 ± 1.5), and Global Perceived Effect was reported to be positive in 16 patients at two years following the procedure. Conclusion Cooled radiofrequency denervation showed long-term efficacy for up to two years in the treatment of sacroiliac joint pain. PMID:23869175

    2011-01-01

    The anterior cruciate ligament (ACL) is the most commonly-injured knee ligament during sporting activities. After injury, most individuals experience episodes of the knee giving way during daily activities (non-copers). Non-copers demonstrate asymmetrical quadriceps strength and movement patterns which could have long-term deleterious effects on the integrity of the knee joint. The purpose of this study was to determine if non-copers resolve their strength and movement asymmetries within two years after surgery. 26 non-copers were recruited to undergo pre-operative quadriceps strength testing and 3-dimensional gait analysis. Subjects underwent surgery to reconstruct the ligament followed by physical therapy focused on restoring normal range of motion, quadriceps strength, and function. Subjects returned for quadriceps strength testing and gait analysis six months and two years after surgery. Acutely after injury, quadriceps strength was asymmetric between limbs, but resolved six months after surgery. Asymmetric knee angles, knee moments, and knee and hip power profiles were also observed acutely after injury and persisted six months after surgery despite subjects achieving symmetrical quadriceps strength. Two years after surgery, quadriceps strength in the involved limb continued to improve and most kinematic and kinetic asymmetries resolved. These findings suggest that adequate quadriceps strength does not immediately resolve gait asymmetries in non-copers. They also suggest that non-copers have the capacity to improve their quadriceps strength and gait symmetry long after ACL reconstruction. PMID:21592482

    Immunotherapy has proven to be effective in controlling allergic asthma. However, few studies have evaluated whether the control and reduction of drug treatment persist after treatment ends. To evaluate the effect of immunotherapy with mites in asthma patients after two years of its suspension on drug treatment and number of exacerbations. Observational study ambispective with active group (immunotherapy and pharmacotherapy) and control (only pharmacotherapy) group followed up for 5 years divided into two phases: 3 years of application of immunotherapy and two year of follow-up after its suspension. 122 patients in the active group and 384 in the control group were included. Both groups had fewer exacerbations after the sixth month (p = 0.04). After nine months the active group had a significant reduction in the use of inhaled steroids (p = 0.05) compared to the control group. Two years after finished immunotherapy, patients in the active group received a lower inhaler doses than the control group. Children under 14 years mono-sensitized had the best response in all parameters evaluated. The allergen immunotherapy improves asthma control and reduces the required doses of pharmacotherapy. These effects have an important impact on quality of life and perhaps economically for patients with asthma. The beginning at an early age seems to have a major impact.

    Full Text Available Temperate estuarine beaches are an asset to coastal cities. Being located within the transition zone where the river meets the sea can provide several environmental benefits such as warm water temperature during the summer, flat waters, protection from coastal upwelling-induced morning fog, as well as additional recreational and cultural values. In this study we address a major question—can the urban water cycle impair the water quality dynamics during a bathing season in a temperate Atlantic estuary (Douro, Northwest Portugal? Water quality was assessed according to the EU legal criteria at different time scales. No daily, weekly, or monthly patterns for microbiological descriptors were found, which rather followed the hourly tidal dynamics. Quality decreased during high tide, affecting potentially 800+ beach-users during mid-summer weekends (4 m2 per person. Low water quality was transported upstream from highly populated urban areas. Therefore, the understanding of the dynamics of estuarine systems is essential to adapt the standard official approach, and the obtained results can be used to draw policy recommendations to improve the sampling strategy, aiming for more accurate assessment of the water quality to reduce the risk hazard of estuarine beaches.

    We show ground-penetrating radar (GPR) reflection data collected over modern and fossil beach deposits from different localities along coastlines in meso-tidal regimes of Greenland and micro-tidal regimes of Denmark. The acquired reflection GPR sections show several similar characteristics but also some differences. A similar characteristic is the presence of downlapping reflections, where the downlap point is interpreted to mark the transition from upper shoreface to beachface deposits and, thus, be a marker of a level close to or at sea-level at the time of deposition. Differences in grain size of the investigated beach ridge system result in different scattering characteristics of the acquired GPR data. These differences call for tailored, careful processing of the GPR data for optimal imaging of internal beach ridge architecture. We outline elements of the GPR data processing of particular importance for optimal imaging. Moreover, we discuss advantages and challenges related to using GPR-based proxies of sea-level as compared to other methods traditionally used for establishment of curves of past sea-level variation.

    Two-year colleges play an important role in developing a competent and creative geoscience workforce, teaching science to pre-service K-12 teachers, producing earth-science literate citizens, and providing a foundation for broadening participation in the geosciences. The Supporting and Advancing Geoscience Education in Two-Year Colleges (SAGE 2YC) project has developed web resources for geoscience faculty on the preparation and support of students in two-year colleges (2YCs). Online resources developed from two topical workshops and several national, regional, and local workshops around the country focus on two main categories: Career Preparation and Workforce Development, and Supporting Student Success in Geoscience at Two-year Colleges. The Career Preparation and Workforce Development resources were developed to help faculty make the case that careers in the geosciences provide a range of possibilities for students and to support preparation for the geoscience workforce and for transfer to four-year programs as geoscience majors. Many two-year college students are unaware of geoscience career opportunities and these materials help illuminate possible futures for them. Resources include an overview of what geoscientists do; profiles of possible careers along with the preparation necessary to qualify for them; geoscience employer perspectives about jobs and the knowledge, skills, abilities and attitudes they are looking for in their employees; employment trends in sectors of the economy that employ geoscience professionals; examples of geotechnician workforce programs (e.g. Advanced Technological Education Centers, environmental technology programs, marine technician programs); and career resources available from professional societies. The website also provides information to support student recruitment into the geosciences and facilitate student transfer to geoscience programs at four- year colleges and universities, including sections on advising support before

  2. Evaluation of potential sources and transport mechanisms of fecal indicator bacteria to beach water, Murphy Park Beach, Door County, Wisconsin

    Fecal Indicator Bacteria (FIB) concentrations in beach water have been used for many years as a criterion for closing beaches due to potential health concerns. Yet, current understanding of sources and transport mechanisms that drive FIB occurrence remains insufficient for accurate prediction of closures at many beaches. Murphy Park Beach, a relatively pristine beach on Green Bay in Door County, Wis., was selected for a study to evaluate FIB sources and transport mechanisms. Although the relatively pristine nature of the beach yielded no detection of pathogenic bacterial genes and relatively low FIB concentrations during the study period compared with other Great Lakes Beaches, its selection limited the number of confounding FIB sources and associated transport mechanisms. The primary sources of FIB appear to be internal to the beach rather than external sources such as rivers, storm sewer outfalls, and industrial discharges. Three potential FIB sources were identified: sand, swash-zone groundwater, and Cladophora mats. Modest correlations between FIB concentrations in these potential source reservoirs and FIB concentrations at the beach from the same day illustrate the importance of understanding transport mechanisms between FIB sources and the water column. One likely mechanism for transport and dispersion of FIB from sand and Cladophora sources appears to be agitation of Cladophora mats and erosion of beach sand due to storm activity, as inferred from storm indicators including turbidity, wave height, current speed, wind speed, sky visibility, 24-hour precipitation, and suspended particulate concentration. FIB concentrations in beach water had a statistically significant relation (p-value ‹0.05) with the magnitude of these storm indicators. In addition, transport of FIB in swash-zone groundwater into beach water appears to be driven by groundwater recharge associated with multiday precipitation and corresponding increased swash-zone groundwater discharge at

    Full Text Available An intensive rotational grazing system for dwarf and late heading (DL elephant grass (Pennisetum purpureum Schumach pasture was examined in a summer period for two years following establishment. Four 0.05 of DL elephant grass pastures (20×25 m were established on May 2003. They were rotationally grazed for 1 week, followed by a 3-week rest period by three breeding or raising beef cattle for three and six cycles during the first and second years of establishment respectively. Before grazing, the plant height, leaf area index and the ratio of leaf blade to stem were at the highest, while tiller number increased and herbage mass tended to increase, except for the first grazing cycle both two years and for one paddock in the second year. Herbage consumption, the rate of herbage consumption and dry matter intake tended to decrease in three paddocks from the first to the third cycle in the first year, but increase as grazing occurred in the second year. Dry matter intake averaged 10.2-14.5 and 15.4–23.2 g DM/kg/live weight (LW/day over the four paddocks in the first and second year, respectively, and average daily gains were 0.09 and 0.35 kg/head/day in the first and second year respectively. The carrying capacities were estimated at 1,016 and 208 cow-days (CD/ha (annual total 1,224 CD/ha in the first year and 1,355 and 207 CD/ha (annual total 1,562 CD/ha in the second year.

    A two-year in-situ phytoremediation trial was launched in Shenyang Zhangshi (Sewage) Irrigation Area (SZIA). The phytoremediation efficiency of Solanum nigrum L. was determined, by both monitoring the change of soil Cadmium level in the upper 20 cm of soil, and calculating the plant uptake of soil Cd. After two years experimental, by monitoring the soil Cd concentrations, The Cd concentrations decreased on average from 2.75 mg kg(-1)to 2.45 mg kg(-1) in the first year and from 2.33 mg kg(-1) to 1.53 mg kg(-1) in the second year, amounting to a decrease by a factor of 10.6% in the first year and 12% in the second year. After two years phytoremediation by S. nigrum, Cd concentrations of the seven experimental plots with S. nigrum growth decreased from 2.75 mg kg(-1) to 1.53 mg kg(-1), a decrease by a factor of 24.9%. And the soil Cd concentration decreased only 2.1% and 1.7% in the bared experimental plot. And the calculating of Cd uptake by S. nigrum shown that, the plants uptake 4.46% and 5.18% of the total soil Cd in 2008 and 2009, while the soil Cd concentrations decreased by a factor of 10.6% in 2008 and 12.1% in 2009.

  19. Off Label Use of Botulinum Toxin in Children under Two Years of Age: A Systematic Review

    Claudia Druschel

    2013-01-01

    Full Text Available The treatment of children with cerebral palsy with Botulinum Toxin is considered safe and effective, but is only approved for children older than two years of age. The effect of BoNT-A injection on juvenile skeletal muscle especially on neuromuscular junction density, distribution and morphology is poorly delineated and concerns of irreversible damage to the motor endplates especially in young children exist. In contrast, earlier treatment could be appropriate to improve the attainment of motor milestones and general motor development. This review systematically analyzes the evidence regarding this hypothesis. A database search, including PubMed and Medline databases, was performed and all randomized controlled trials (RCTs comparing the efficacy of Botulinum Toxin in children younger than two years were identified. Two authors independently extracted the data and the methods of all identified trials were assessed. Three RCTs met the inclusion criteria. The results of the analysis revealed an improvement in spasticity of the upper and lower extremities as well as in the range of motion in the joints of the lower limbs. However, evidence of an improvement of general motor development could not be found, as the assessment of this area was not completely specified for this patient group. Based on available evidence it can not be concluded that Botulinum Toxin treatment in children younger than two years improves the achievement of motor milestones. However, there is evidence for the reduction of spasticity, avoiding contractures and delaying surgery. Due to some limitations, the results of this review should be cautiously interpreted. More studies, long-term follow up independent high-quality RCTs with effectiveness analyses are needed.

    Full Text Available To study the predictive value of preoperative magnetic resonance imaging (MRI findings for the two-year postoperative clinical outcome in lumbar spinal stenosis (LSS.84 patients (mean age 63±11 years, male 43% with symptoms severe enough to indicate LSS surgery were included in this prospective observational single-center study. Preoperative MRI of the lumbar spine was performed with a 1.5-T unit. The imaging protocol conformed to the requirements of the American College of Radiology for the performance of MRI of the adult spine. Visual and quantitative assessment of MRI was performed by one experienced neuroradiologist. At the two-year postoperative follow-up, functional ability was assessed with the Oswestry Disability Index (ODI 0-100% and treadmill test (0-1000 m, pain symptoms with the overall Visual Analogue Scale (VAS 0-100 mm, and specific low back pain (LBP and specific leg pain (LP separately with a numeric rating scale from 0-10 (NRS-11. Satisfaction with the surgical outcome was also assessed.Preoperative severe central stenosis predicted postoperatively lower LP, LBP, and VAS when compared in patients with moderate central stenosis (p<0.05. Moreover, severe stenosis predicted higher postoperative satisfaction (p = 0.029. Preoperative scoliosis predicted an impaired outcome in the ODI (p = 0.031 and lowered the walking distance in the treadmill test (p = 0.001. The preoperative finding of only one stenotic level in visual assessment predicted less postoperative LBP when compared with patients having 2 or more stenotic levels (p = 0.026. No significant differences were detected between quantitative measurements and the patient outcome.Routine preoperative lumbar spine MRI can predict the patient outcome in a two-year follow up in patients with LSS surgery. Severe central stenosis and one-level central stenosis are predictors of good outcome. Preoperative finding of scoliosis may indicate worse functional ability.

    2013-04-01

    The aim of this study was to evaluate radiographically the periapical status and technical standard of root canal therapies performed by a group of undergraduate dental students in Turkey two years following completion of the treatments. A random sample of 264 patients who received root canal treatment from undergraduate students at the Yeditepe University Faculty of Dentistry in 2009 were recalled after two years. The study sample consisted of 319 root-filled teeth in 158 dental patients (females=97, males=61) who presented to the student clinics during that time frame. For each root-filled tooth, two periapical radiographs were examined to identify the periapical status, one showing pre-treatment and the other showing post-treatment status. The quality of endodontic treatment was examined according to the distance between the end of root filling and radiographic apex and the density of the obturation according to presence of voids within the root filling material. This examination found that 54.2 percent of roots had fillings of acceptable length, while 37.3 percent were short, 7.8 percent were overfilled, and 0.6 percent was unfilled; 2.5 percent of the teeth were observed with broken root canal instruments. After two years, PAI scores of teeth with acceptable length of root canal filling (0-2 mm from the radiographic apex) were found to be lower than those of the overfilling and short filling cases (>2mm) (pcanal fillings of 52.7 percent of endodontically treated teeth. The PAI scores of root fillings with inadequate density were significantly higher than adequate ones (p<0.01). Although endodontic treatments performed by undergraduate students do not appear to be unqualified compared to those performed by general practitioners, more emphasis must be placed on the technical quality of endodontic treatment to obtain better results.

    2016-01-01

    Background Pneumonia is a common cause of illness and death in older adults (≥65 years of age). Pneumonia prediction models could be used by clinicians in counseling patients and by policy makers and researchers for risk adjustment. Objectives To develop three prognostic indices, which vary in degree of detail required, for two-year pneumonia risk in older adults. Setting Community-dwelling enrollees in Group Health (GH), an integrated healthcare delivery system. Participants The study included 3,375 subjects enrolled in the Adult Changes in Thought study. Participants were ≥65 years of age, dementia-free, and enrolled in GH for at least two years prior to start of follow-up. Subjects were divided into development (n=2,250) and validation (n=1,125) cohorts. Exposures Questionnaire data and interviewer assessments on functional status, medical history, smoking and alcohol use, cognitive function, personal care, problem solving, physical measures including grip strength and gait speed, and administrative database information on comorbid illnesses, laboratory tests, and prescriptions dispensed. Main outcome Incident community-acquired pneumonia, defined presumptively from administrative data and validated by medical record review. Results Participants (59% female) contributed 12,998 visits at which risk factors were assessed; 642 pneumonia events were observed during follow-up. Age, sex, chronic obstructive pulmonary disease and congestive heart failure, body mass index, and use of inhaled or oral corticosteroids were key predictors in all prognostic indices. A risk score based on these seven variables, which are commonly available in electronic medical records, had equal or better performance (c-index, 0.69 in the validation cohort) than scores including more detailed data such as functional status. Conclusion Data commonly available in electronic medical records can stratify older adults into groups with varying subsequent two-year pneumonia risk. PMID:27401847

    With community college and two-year program students playing pivotal roles in advancing the nation's STEM agenda now and throughout the remainder of this young millennia, it is incumbent on educators to devise innovative and sustainable STEM initiatives to attract, retain, graduate, and elevate these students to four-year programs and beyond. Involving these students in comprehensive, holistic research experiences is one approach that has paid tremendous dividends. The New York City College of Technology (City Tech) was recently awarded a National Science Foundation Research Experiences for Undergraduates (REU) supplemental grant to integrate a community college/two-year program component into its existing REU program. The program created an inviting and supportive community of scholars for these students, nurtured them through strong, dynamic mentoring, provided them with the support structures needed for successful scholarship, and challenged them to attain the same research prominence as their Bachelor degree program companions. Along with their colleagues, the community college/two-year program students were given an opportunity to conduct intensive satellite and ground-based remote sensing research at the National Oceanic and Atmospheric Administration Cooperative Remote Sensing Science and Technology Center (NOAA-CREST) at City College and its CREST Institute Center for Remote Sensing and Earth System Science (ReSESS) at City Tech. This presentation highlights the challenges, the rewards, and the lessons learned from this necessary and timely experiment. Preliminary results indicate that this paradigm for geoscience inclusion and high expectation has been remarkably successful. (The program is supported by NSF REU grant #1062934.)

    To compare the respiratory and neurological outcomes at two years of age of preterm children born before 33 weeks of gestation (WG) after early preterm premature rupture of membranes (EPPROM) between 14 and 24 WG with preterm children without EPPROM. This single-center case-control retrospective study was conducted at Rouen University Hospital between 1st January 2000 and 31st December 2010. All the cases with EPPROM born from 26WG to 32WG were included. Each newborn was matched by sex, gestational age (GA) and year of birth to two very preterm children, born without EPPROM. At two years of corrected age, motor and cognitive abilities were assessed by routine score based on the Amiel-Tison and Denver developmental scales. Ninety-four cases with EPPROM before 24WG have been included. The 31 children born from 26WG to 32WG were matched with 62 controls. The EPPROM group had poorer clinical evaluation at one year for motor (p = 0.003) and cognitive developmental scores (p = 0.016). Neuromotor rehabilitation was performed more often (p = 0.013). However, there was no difference at 2 years of age. Children born after EPPROM were hospitalized more often for bronchiolitis (pyears, which correlates with increased incidence of pneumothorax (p = 0.017), pulmonary hypoplasia (p = 0.004) and bronchopulmonary dysplasia (p = 0.005) during neonatal period. At two years, despite an increase in severe bronchiolitis and the need for more neuromotor rehabilitation during the first month of the life after discharge, there was no difference in neurological outcomes in the very preterm children of the EPPROM group compared to those born at a similar GA without EPPROM.

  5. Two years later - Revisiting autobiographical memory representations in vmPFC and hippocampus.

    Bonnici, Heidi M; Maguire, Eleanor A

    2018-02-01

    A long-standing question in memory neuroscience concerns how and where autobiographical memories of personal experiences are represented in the brain. In a previous high resolution multivoxel pattern analysis fMRI study, we examined two week old (recent) and ten year old (remote) autobiographical memories (Bonnici et al., 2012, J. Neurosci. 32:16982-16991). We found that remote memories were particularly well represented in ventromedial prefrontal cortex (vmPFC) compared to recent memories. Moreover, while both types of memory were represented within anterior and posterior hippocampus, remote memories were more easily distinguished in the posterior portion. These findings suggested that a change of some kind had occurred between two weeks and ten years in terms of where autobiographical memories were represented in the brain. In order to examine this further, here participants from the original study returned two years later and recalled the memories again. We found that there was no difference in the detectability of memory representations within vmPFC for the now 2 year old and 12 year old memories, and this was also the case for the posterior hippocampus. Direct comparison of the two week old memories (original study) with themselves two years later (present study) confirmed that their representation within vmPFC had become more evident. Overall, this within-subjects longitudinal fMRI study extends our understanding of autobiographical memory representations by allowing us to narrow the window within which their consolidation is likely to occur. We conclude that after a memory is initially encoded, its representation within vmPFC has stablised by, at most, two years later. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    To investigate cognitive outcomes after frontal lobe resection (FLR) for epilepsy in a consecutive single centre series. Neuropsychological examinations were performed prior to and two years (mean test interval 2.5 years) after surgery in 30 consecutive patients who underwent FLR. Cognitive outcome was evaluated with particular consideration to the site of surgery (lateral, premotor/SMA [supplementary motor area], mesial/orbital). Cognitive domains assessed were speed, language, memory, attention, executive functions and intelligence. 25 healthy controls were assessed at corresponding time points (mean test interval 3.0 years). Analyses were made both at group and individual levels. At baseline the patients performed below controls in variables depending on speed, executive functions, global and verbal intelligence. Two years after surgery, the analyses at the subgroup level indicated that the lateral resection group had less improvement than the controls in global intelligence, FSIQ (p=.037). However, at the individual level, the majority of the change scores (74-100%) were classified as within the normal range for all but one variable. The exception was the variable "Comprehension" (measuring verbal reasoning ability) with reliable declines in 44% (8/18) of the patients. This pattern of decline was observed in the lateral (4/7 patients) and premotor/SMA (4/7 patients) resection groups. Seizure outcome and side of surgery did not influence these results. The main finding was cognitive stability at group level two years after FLR. A reliable decline in verbal reasoning ability was rather common at an individual level, but only in the lateral and premotor/SMA resection groups. The lateral resection group also had less improvement than the controls in global intelligence. Copyright © 2015 British Epilepsy Association. Published by Elsevier Ltd. All rights reserved.

    The paper evaluates the results of data obtained from two years of observing an actual domestic wastewater treatment plant (WWTP) with an immersed membrane module. The domestic MBR (membrane bioreactor) WWTP was linked to a dwelling with four residents. Two different commercial flat sheet membrane modules were investigated. The membrane modules, as well as the whole WWTP, were tested with different fluxes as well as the response of the membrane and activated sludge to different conditions, such as actual peak wastewater flows, extremes temperatures (a winter below 5 °C), and high pH values.

  9. Hyperparathyroidism Two Years after Radioactive Iodine Therapy in an Adolescent Male

    Full Text Available Primary hyperparathyroidism is a very rare complication following radioactive iodine therapy. There is typically a latency period of more than a decade following radiation exposure and, therefore, it is observed almost exclusively in adults. Consequently, pediatricians are not aware of the association. We present a case of primary hyperparathyroidism due to a solitary parathyroid adenoma occurring in an adolescent male two years following radioactive iodine treatment for papillary thyroid carcinoma. Periodic screening of serum calcium following ablative doses of radioactive iodine for thyroid cancer may be justified even in adolescents.

    Undergraduate research experiences are important for the development of expertise in geoscience disciplines. These experiences have been shown to help students learn content and skills, promote students' cognitive and affective development, and develop students' sense of self. Early exposure to research experiences has shown to be effective in the recruitment of students, improved retention and persistence in degree programs, motivation for students to learn and increase self-efficacy, improved attitudes and values about science, and overall increased student success. Just as departments at four-year institutions (4YCs) are increasingly integrating research into their introductory courses, two-year college (2YC) geoscience faculty have a great opportunity to ground their students in authentic research. The Undergraduate Research with Two-year College Students website developed by SAGE 2YC: Supporting and Advancing Geoscience Education at Two-year Colleges provides ideas and advice for 2YC and 4YC faculty who want to get more 2YC students involved in research. The continuum of possibilities for faculty to explore includes things that can be done at 2YCs (eg. doing research as part of a regular course, developing a course specifically around research on a particular topic, or independent study), done in collaboration with other local institutions (eg. using their facilities, conducting joint class research, or using research to support transfer programs), and by involving students in the kind of organized Undergraduate Research programs run by a number of institutions and organizations. The website includes profiles illustrating how 2YC geoscience faculty have tackled these various models of research and addressed potential challenges such as lack of time, space, and funding as part of supporting the wide diversity of students that attend 2YCs, most of whom have less experience than that of rising seniors who are the traditional REU participant.

    Necrotizing fasciitis of the perineum and external genitalia is a life-threatening infective gangrene, primarily seen in adults. It may be seen at any age but it is relatively uncommon in children. Here, we report a case of Fournier’s gangrene in a two year old male child who was treated aggressively with broad spectrum antibiotics and early surgical debridement with hemodynamic stabilization. Even though no obvious precipitating cause was identified, hygiene was thought to be the inciting factor. Early surgical debridement with appropriate antibiotics and aggressive supportive care gave good results. PMID:25302233

    Full Text Available Abstract Introduction It has been previously unclear whether a "mild" degree of low carbohydrate or "starvation" ketonemia and acidosis induced by a low carbohydrate diet is clinically relevant to a patient. Case presentation A 30-year-old Caucasian male on a low carbohydrate diet presented with nausea, vomiting and abdominal pain. The patient's bicarbonate level was 12 and he had hyperglycemia and ketonemia. He was felt to be in diabetic ketoacidosis and was started on intravenous insulin and isotonic saline infusions and responded well. Following cessation of insulin therapy, the patient remained normoglycemic for the remainder of his hospital stay. He later admitted to having been on the South Beach Diet, which is a low carbohydrate diet, for the three weeks prior to his presentation and during which time he had lost 16 pounds. On admission his BMI was 27.1. On presentation, the patient was felt to be in diabetic ketoacidosis but, interestingly, he was subsequently euglycemic without therapy. Following discharge, the patient discontinued the diet plan and he has remained asymptomatic and euglycemic over the following two years. Conclusion The hyperglycemic ketoacidosis in this patient may have been caused by increased concentrations of free fatty acids in the absence of carbohydrate-induced inhibition of beta-oxidation of fatty acids and in the presence of an abnormally high ratio of glucagons to insulin. Given the present day popularity of low-carbohydrate diet plans, healthcare providers should be aware of the apparent association between such diets and symptomatic ketoacidosis. In a patient with ketoacidosis suspected to be secondary to a low carbohydrate diet, all other causes of high anion gap acidosis should be ruled out before attributing the acidosis to the low carbohydrate diet.

    Full Text Available This article explores beachcombing and gleaning as practices that combine mobility with daydreaming and which allow us to experience our environment with the perception of ‘tactile nearness’ (Benjamin. Through eco-poetics shaped by ‘inconceivable analogies and connections’ (Benjamin, the author re-imagines a neglected space used as a short-cut on the way to work—the Liverpool Adelphi car park in Liverpool—as “Car Park Beach”. Inspired by the situationists’ slogan ‘Sous les pavés, la plage’, the author argues that Car Park Beach opens up imaginative possibilities for a different form of ecological encounter with our own precarity, one ushered in by a ‘close-up’ awareness of how waste transforms our world. Car Park Beach is a site that the author associates with the drift-like, distracted movements of both people and matter, and this article therefore attempts to deploy an equivalent method of analysis. Drawing on her own practice of gleaning photos and objects on the way to work, the author places a vocabulary of flotsam and jetsam at the axis of her discussion. Allusive, often layered, connections are followed between a diverse range of sources including beachcombing guides, literary memoirs, documentary films, eco-criticism, and auto-ethnography.

  15. Application of GIS in Beach Placer Exploration

    Application of Geographic Information System (GIS) in beach placer exploration combines the activities of data collection, organisation, visualisation, query, analysis and prediction. GIS has the potential to enhance the capability for creative data analysis, modelling and interpretation. Exploration software and GIS are essential tools for geoscientists searching for mineral deposits. GIS technology has come a long way in the past fifteen years, especially in data handling, analysis, visualization etc. Modern technology and solutions are now evolving to allow geoscientists to share data easily between mapping platforms and enterprise level GIS environments. In beach placer exploration programme, data handling and processing are the main challenging tasks due to generation and processing of large volume of field and laboratory data of the areas under investigation. Though there are limitations in visualising map data as a single map on a screen, due to its non-proportionate lengths and widths, a GIS can very well handle all these varied datasets to demarcate highly potential zones within a narrow coastal strip. Generally these datasets contain information from thousands of drillholes about their location co-ordinates, depth, height, description and thickness of lithounits, water table level, radioactivity and other pertinent subsurface properties. Field data collection can be efficiently done using a hand held global positioning system (GPS) installed with mobile-GIS application and data handling software

    Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0-14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11-12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red 'beach closed' flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.

    2016-01-01

    Thyroid nodules are less common among children than among adults. By contrast, thyroid nodules are more often malignant in childhood than in adulthood. In children, 26% of thyroid nodules are malignant, while in adults the corresponding value is 5-10%. Risk factors for developing thyroid nodules in children are female sex, post-pubertal age, previous or co-existing thyroid disease, previous irradiation of the neck, and a family history of thyroid disease. In children younger than 10 years, when no risk factors are present, the incidence rates are practically negligible. A two-year-old girl presented with a right thyroid mass. Laboratory evaluation revealed normal levels of triiodothyronine and thyroid-stimulating hormone. Thyroid ultrasonography revealed a 4.8 × 3.2 × 2.5 cm nonhomogenous nodule. The patient underwent right hemithyroidectomy. The pathology was consistent with papillary thyroid carcinoma; therefore, total thyroidectomy and selective neck dissection were performed. We report a very rare case of papillary thyroid carcinoma in a two-year-old child with no risk factors. The detection of a thyroid nodule in such a young child with no pre-disposing risk factors does not exclude the possibility of thyroid carcinoma and warrants careful evaluation and appropriate therapy.

    The EES pilot program was initiated in August 1977, when 10 states were selected on a competitive basis for participation. The pilot states (Alabama, Connecticut, Michigan, New Mexico, Pennsylvania, Tennessee, Texas, Washington, Wisconsin, and Wyoming) devoted the first 6 months to start-up activities. This document is a follow-up report to the three volume Evaluation Summary of the first year of the pilot EES program published in September 1979. The purpose of this report is to provide an overview of the impacts and costs of the two years of the pilot program, and to check the consistency of findings over the two year period. The analysis addresses the following: (1) were the impact findings of Year I and Year II consistent, or did Year I and Year II attitudes and behavior vary. If variation existed, could it be attributed to program changes as the EES progressed from a start-up phase (Year I) to more normal service delivery (Year II); and (2) did costs of service delivery change (again reflecting start-up and normal service delivery costs). Did cost changes affect conclusions about the relative cost effectiveness of delivering services to different target audiences.

    Background Although depressive symptoms are common postpartum, few studies have followed women beyond 12 months postpartum to investigate changes in the number and severity of these symptoms over time, especially in overweight and obese women. Using two complementary analytical methods, this study aims to identify trajectories of depressive symptoms over two years postpartum among overweight or obese mothers, and assess the demographic, socio-economic , and health covariates for these trajectories. Methods Using longitudinal data from two behavioral intervention studies (KAN-DO and AMP; N = 844), we used latent growth modeling to identify the overall trajectory of depressive symptoms and how it was related to key covariates. Next, we used latent class growth analysis to assess the heterogeneity in the depressive symptom trajectories over time, and thereby, identify subgroups of women with distinct trajectories. Findings The overall trajectory of depressive symptoms over two years postpartum was relatively stable in our sample. However, the presence of three distinct latent class trajectories [stable-low (82.5%), decreasing symptoms (7.3%) and increasing symptoms (10.2%)], identified based on trajectory shape and mean depressive symptom score, supported heterogeneity in depressive symptom trajectories over time. Lower maternal education was related to a higher symptom score, and poorer subjective health status at baseline predicted inclusion in the increasing symptoms trajectory. Conclusions In some overweight or obese mothers postpartum depressive symptoms do not resolve quickly. Practitioners should be aware of this phenomenon and continue to screen for depression for longer periods of time postpartum. PMID:25213748

    The increasing absolute number of paediatric CT scans raises concern about the safety and efficacy and the effects of consecutive diagnostic ionising radiation. To demonstrate a method to evaluate the lifetime attributable risk of cancer incidence/mortality due to a single low-dose helical chest CT in a two-year patient cohort. A two-year cohort of 522 paediatric helical chest CT scans acquired using a dedicated low-dose protocol were analysed retrospectively. Patient-specific estimations of radiation doses were modelled using three different mathematical phantoms. Per-organ attributable cancer risk was then estimated using epidemiological models. Additional comparison was provided for naturally occurring risks. Total lifetime attributable risk of cancer incidence remains low for all age and sex categories, being highest in female neonates (0.34%). Summation of all cancer sites analysed raised the relative lifetime attributable risk of organ cancer incidence up to 3.6% in female neonates and 2.1% in male neonates. Using dedicated scan protocols, total lifetime attributable risk of cancer incidence and mortality for chest CT is estimated low for paediatric chest CT, being highest for female neonates. (orig.)

    Young athletes at the stage of growth acceleration tend to exhibit increased susceptibility to postural abnormalities, especially in the trunk region. The aim of this study was to assess and compare the posture in male adolescent handball players over two years of regular training sessions. The study group comprised 21 handball players. At the start of the study 15 participants were aged 14 and 6 participants were aged 15 (mean 14.25 ± 0.58). The measurements were repeated three times. Posture was assessed with a photogrammetric method based on the moiré phenomenon. The analysis of posture relative to symmetry in the frontal and transverse planes did not reveal any significant differences between posture indicators obtained during the successive measurements. Sagittal plane posture indicators revealed significant changes in torso forward inclination angle and the shape of anteroposterior spinal curvatures. The latter consisted of significant deepening of the upper thoracic curve (angle α) and flattening of the lumbosacral curve (angle γ). A two-year period of handball training did not result in posture asymmetries in young male handball players. The observed changes in the shape of anteroposterior spinal curvatures might be related both to sports training and somatic parameters.

    Full Text Available ABSTRACT Objective: To report the outcomes of non-endoscopic percutaneous cervical discectomy by anterior blunt approach for the treatment of degenerative disc disease. Methods: A review of the medical records of patients with axial cervical pain resulting from degenerative disc disease and treated with discectomy and percutaneous nucleoplasty by anterior blunt approach with radiofrequency source was carried out. The data were evaluated according to modified MacNab and pre- and postoperative VAS criteria at 3, 12 and 24 months. Results: Sixty-two procedures were performed in 48 patients between 2008 and 2014. The mean age of the population was 52.4 years. MacNab results were 84.6%, 92.3%, and 89.2% improvement (excellent and good results at 3, 12 and 24 months, respectively. The VAS changed from 7.4 to 2.3 two years after the procedure, showing a statistically significant difference (p=0.000. There were no major complications or re-interventions related to the technique. Conclusions: Anterior non-endoscopic discectomy and nucleoplasty for the treatment of discogenic axial cervical pain may be an effective alternative to open surgery. In the two-year follow-up, our blunt technique proved to be a safe procedure with no approach-related complications, and provided outcomes comparable to those reported using the original needle technique.

    Geoscience faculty at two-year colleges (2YC) face a number of challenges, from the wide diversity of the student population to being isolated from other geoscience faculty. Several projects have developed web resources that address some of these issues by providing professional development, teaching materials, and opportunities to connect with their colleagues at other institutions. The Role of Two-Year Colleges in Geoscience Education and in Broadening Participation in the Geosciences project brought together 2YC faculty from across the country for a planning workshop to discuss these issues and propose strategies and mechanisms to strengthen the 2YC geoscience education community (http://serc.carleton.edu/geo2yc/index.html). The website now hosts more than 30 essays on the state of 2YC education, teaching activities, and course descriptions submitted by 2YC faculty as well as an email discussion list and other ways of networking and discussing important. One outcome of this work is that the National Association of Geoscience Teachers has created a division for 2YC faculty so that members can network with each other and discuss solutions to pressing issues. (http://nagt.org/nagt/divisions/2yc/index.html) The On the Cutting Edge program has an array of professional development resources available (http://serc.carleton.edu/NAGTWorkshops/). Over its decade of work, the program has developed resources on topics of interest to 2YC faculty including: teaching introductory courses, the affective domain, teaching with data, metacognition, online courses, teaching about hazards, and many others. There are also extensive collections of teaching activities and visualizations. In addition, the program continues to hold face-to-face and virtual professional development workshops and webinars that are accessible to 2YC faculty and can help them feel less isolated The Starting Point: Teaching Introductory Geoscience (http://serc.carleton.edu/introgeo) website is specifically

    The aim of the study was to establish the efficacy of anti VEGF (Vascular Endothelial Growing Factor) drugs in the treatment of wet form ARMD (Age-Related Macular Degeneration) in everyday clinical practice in the Department of Ophthalmology, Faculty Hospital, Hradec Králové, Czech Republic, E.U., in patients registered in the Czech national registry AMADEUS. Retrospective study with 24 months follow-up period. In the group were evaluated 143 eyes of 140 patients, out of them were 77 women (65.8 %), of average age 73.09 (71.69 - 74.48) years, and 40 men (34.2 %) of average age 74 (58 - 85) years. All of the patients were completely examined before the beginning of the treatment; during the treatment were, except the standardized eye examination, in patients treated with ranibizumab the color fundus photography and Optical Coherence Tomography (OCT) with measuring of the central retinal thickness performed every three months at least. The patients treated by pegaptanib were examined every six weeks before the drug application. The fluorescence angiography (FA) was performed at the beginning of the treatment to establish the type and extension of the choroidal neovascularization and during the treatment in case of necessity to establish the activity of the choroidal neovascular membrane (CNV). The treatment by ranibizumab was in the regimen PRN (pro re nata), and pegaptanib was applied every six months during the first year with the follow-up evaluation of the findings. The treatment evaluations were performed at 12 and 24 months. During the two years follow - up period, the authors noticed in patients treated with ranibizumab loss of 5.12 letters of ETDRS optotypes in case of mostly classical CNV, in occult CNV loss of 5.45 letters, and in minimally classical CNV loss of 2.83 letters. In three evaluated eyes with classical CNV in patients treated with pegaptanib we noticed after 2 years loss of 6.67 letters, in eleven eyes with occult CNV we established loss of 9

    Beaches are dynamic transitional environments subject to numerous natural and anthropic alterations. In these ecosystems, the infralittoral-sublittoral macrofauna communities play a key role in the food web. The objective of this study was to compare macrofauna communities on six beaches on the Gulf of Cádiz coast, which were classified according to the anthropic alterations they support, and evaluate the influence of abiotic factors on the species distribution. Sampling was done in the infralittoral-sublittoral zone of each beach using a modified manual dredge. Five perpendicular transects of 25 m, each separated by 10 m, were performed per beach, with a total sample area of 43.75 m 2 per beach. A total of 27 species were found, of which Donax trunculus, Diogenes pugilator, and Tritia grana were the most abundant. Anthropogenic effects are appreciable in the infralittoral-sublittoral although they are areas that are permanently submerged and less exposed than the intertidal. Beach nourishments carried out with large volumes of sand can alter the grain size, the most influential parameter on the distribution of the species, and consequently, affect the macrofauna community that inhabits these beaches.

    In the last two decades there has been a world wide increase in the number of drugs that are being switched from the prescription-only category to non-prescription categories. In Israel, until recently, non-prescription medicines were only permitted to be sold by a pharmacist in pharmacies. In May 2005, following amendments to the law, several non-prescription medicines which were previously sold under a pharmacist's supervision, were reclassified as general-sales-list (GSL) medicines and permitted to be displayed and sold directly off the shelves in pharmacies and in other places such as grocery stores and petrol stations. To study the change in the patterns of consumption of non-prescription drugs in Israel two years after the reform began. A representative sample of the population of Israel was chosen and interviews were conducted at two time points: before the reform commenced and two years after the beginning of the reform. Statistical processing was performed in order to examine the changes in patterns of consumption of non-prescription drugs in Israel between these two time points. In both surveys it was found that: approximately 70% of the Israeli public buys non-prescription medicines; 70% of the people interviewed said that they had been aware of the reform, but of these, about 75% continued buying nonprescription drugs from the pharmacist while 21% bought medicines off the shelves at the pharmacy and 4% purchased medications at grocery stores. The most common reasons for buying medicines off the shelves without a pharmacist were earlier knowLedge about the medication, convenience and availabiLity when the pharmacies were closed. An insignificant difference was observed for the purchase of non-prescription drugs from the different types of pharmacies: the health maintenance organizations (HMO) pharmacies continue to be the leading pharmacies from which the public purchased their non-prescription medicines, white there was a slight increase in the

    Trauma related injuries are a main cause for long-lasting morbidity and disability especially in younger patients with their productive years ahead. On a routine basis, we assessed health related quality of life two years after trauma of severely injured patients at our level-I trauma centre via posted survey. The posted survey included (1) POLO-Chart questionnaire with European Quality of Life (EuroQoL), Short Form Health Survey-36 (SF 36) and the recently developed and validated Trauma Outcome Profile (TOP) combined with (2) single centre data according to TraumaRegister DGU(®) data sets including trauma mechanism, injuries and initial treatment. Inclusion criteria were severely injured patients ≥ 18 years, treated between 2008 and 2010. Exclusion criteria were death, cognitive impairment, lack of German language and denial of participation. 129 datasets were eligible for analysis reflecting a typical trauma collective with mean age 44 years, predominantly male (67%), mean ISS 22 and 98% blunt trauma. Two years after trauma, 62% of the patients reported of relevant remaining pain and 64% of severe functional deficit in at least one body region. Sixty-four percent of the patients suffered from decreased overall quality of life (EuroQoL≤0.8). Additionally, all domains of SF-36 were impaired compared to an age and gender adjusted cohort of healthy individuals, especially domains of pain and activity of daily living. These impairments were associated with decreased 'social functioning' and 'emotional role functioning'. TOP results confirmed these findings: Quality of life was decreased in almost every dimension. TOP additionally identified sequels especially in domains of "Mental Functioning" and impairments in psychological recovery including post-traumatic stress disorder, depression and anxiety. Socioeconomic impairments were frequent including further hospitalisations (62%), duration of inability to work ≥ 6 month (54%), financial disadvantages (45%) and

  18. Brazilian sandy beaches: characteristics, ecosystem services, impacts, knowledge and priorities

    Directory of Open Access Journals (Sweden)

    Antonia Cecília Zacagnini Amaral

    Full Text Available ABSTRACT Sandy beaches constitute a key ecosystem and provide socioeconomic goods and services, thereby playing an important role in the maintenance of human populations and in biodiversity conservation. Despite the ecological and social importance of these ecosytems, Brazilian sandy beaches are significantly impacted by human interference, chemical and organic pollution and tourism, as well as global climate change. These factors drive the need to better understand the environmental change and its consequences for biota. To promote the implementation of integrated studies to detect the effects of regional and global environmental change on beaches and on other benthic habitats of the Brazilian coast, Brazilian marine researchers have established The Coastal Benthic Habitats Monitoring Network (ReBentos. In order to provide input for sample planning by ReBentos, we have conducted an intensive review of the studies conducted on Brazilian beaches and summarized the current knowledge about this environment. In this paper, we present the results of this review and describe the physical, biological and socioeconomics features of Brazilian beaches. We have used these results, our personal experience and worldwide literature to identify research projects that should be prioritized in the assessment of regional and global change on Brazilian sandy beaches. We trust that this paper will provide insights for future studies and represent a significant step towards the conservation of Brazilian beaches and their biodiversity.

    We present systematic spectral analyses of gamma-ray bursts (GRBs) detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first two years of operation. This catalog contains two types of spectra extracted from 487 GRBs, and by fitting four different spectral models, this results in a compendium of over 3800 spectra. The models were selected based on their empirical importance to the spectral shape of many GRBs, and the analysis performed was devised to be as thorough and objective as possible. We describe in detail our procedure and criteria for the analyses, and present the bulk results in the form of parameter distributions. This catalog should be considered an official product from the Fermi GBM Science Team, and the data files containing the complete results are available from the High-Energy Astrophysics Science Archive Research Center.

  20. What We Need: The 2012 NASA EPO Forum Survey on Two-Year College STEM Teaching

    Low, R.; CoBabe-Ammann, E.; Schultz, G.

    2014-07-01

    A survey of community college STEM faculty, administered by the NASA SMD Higher Education Working Group (HEWG), was administered in fall 2012 in an effort to document the demographic make-up and views of community college faculty who teach NASA science-related STEM courses in astronomy, physics, Earth science, and engineering. Nearly half of respondents reported that less than 10% of students in their classroom are “STEMward bound” and indicated the need for STEM resources that can relate science course content and be relevant to the daily life of their students. A number of respondents also noted a new or renewed emphasis on outreach activities within the community served by their institution as part of their job description. The survey suggests specific directions and ways that the NASA SMD EPO forum can support two-year college stakeholders.

    The NEC 250 kV single stage AMS accelerator (SSAMS) was installed two years ago at the Center for Applied Isotope Studies (CAIS), University of Georgia. The accelerator is primarily being used for radiocarbon measurements to test the authenticity of natural and bio-based samples while all other samples such as geological, atmospheric, marine and archaeological. are run on the 500 kV, NEC 1.5SDH-1 model tandem accelerator, which has been operating since 2001. The data obtained over a six months period for OXI, OXII, ANU sucrose and FIRI-D are discussed. The mean value of ANU sucrose observed to be slightly lower than the consensus value. The processed blanks on SSAMS produce lower apparent age compared to the tandem accelerator as expected.

    The technique of functional endoscopic sinus surgery (FESS) has been widely accepted and applied to inflammatory diseases of the paranasal sinuses with internationally reported results of this technique having been very good. Our objective was to find out outcome after FESS at our centre. Two hundred patients who had undergone FESS during a two year period with an average follow-up period of eleven months were evaluated subjectively regarding the outcome of their endoscopic sinus surgery. An overall subjective improvement of about 94% was documented, with improvement in specific symptoms such as headache, nasal congestion, change in sense of smell, nasal discharge and recurrent infections ranging from 52% to 97%. Our center reports a subjective improvement of symptoms following FESS compatible with results attained internationally. (author)

    To make up for the lack of data on 210 Pb aerosol deposition in tropical regions and to use this radionuclide as an aerosol tracer,a monitoring station was run for two years at Petit-Saut, French Guiana. Lead-210 concentration in air at ground level was monitored continuously together with atmospheric total deposition. The air concentration has a mean value of 0.23±0.02 mBq m -3 during both wet and dry seasons, and it is only weakly affected by the precipitation mechanism. This result was unexpected in a wet tropical region, with a high precipitation rate. In contrast, deposition clearly correlates with precipitation for low/moderate rainfall ( -2 y -1 . This provides a procedure fo estimating this mean flux at other sites in French Guiana

    Full Text Available A two-year-old girl child was admitted with complaints of diarrhoea of one week duration in the paediatric ward. She was referred to the skin OPD for gradually progressive skin rashes on both lower limbs noticed since two days. Dermatological examination revealed finding of livedo reticularis. Dietary history revealed maize forming a significant portion of the child′s diet since the age of nine months. The child was treated with a course of Niacin in the form of Nicotinamide 50 mg twice a day for 4 weeks and the parents were advised not to give her maize in the diet. The skin lesions and diarrhoea regressed in duration of two weeks. This is probably the first time that a case of pellagra causing livedo is being reported, that too in a child.

    2017-03-01

    We tested artifactual and theory-based accounts of the relationship between schizophrenia liability and suicidality. At baseline, 387 adolescents (12 to 17years) completed measures of schizotypy, hopelessness, and depressed affect. After two years, schizotypal and non-schizotypal subsamples (n=16 and 31, respectively) self-reported passive suicidal ideation, active ideation, and serious ideation and action. Taxonic schizotypy predicted passive ideation (OR=8.15, 95% CI 1.34, 49.60) even when controlling for depressed affect. Hopelessness did not predict suicidality or moderate schizotypy-suicidality relationships. Findings were consistent with the interpersonal theory of suicide and contrary to the artifactual account of the association. Copyright © 2016 Elsevier B.V. All rights reserved.

    Clinical and radiographic evaluation of the premedicated direct pulp capping using formocresol (PDC) versus conventional direct pulp capping using calcium hydroxide (CDC) in human carious primary molars. A total of 120 vital primary molars with pinpoint exposure during caries removal in 84 patients aged 4-5 years were selected. In the PDC group (n = 60), 20% Buckley's formocresol solution, and in the CDC group (n = 60), calcium hydroxide powder were applied to the exposure sites followed by placement of zinc oxide-eugenol base. Teeth were restored with preformed stainless steel crowns. Clinical and radiographic evaluations of the treatment outcomes were performed at regular intervals of 6 and 12 months, respectively, for two years post-operatively. The prevalence of spontaneous pain, sensitivity on percussion, and fistula were significantly higher in the CDC group compared to the PDC group (P formocresol premedicated direct pulp capping could safely be used as a substitute for conventional direct pulp capping.

    2012-09-01

    A double-lumen, saline-filled breast implant with a baffle structure (IDEAL IMPLANT Saline-Filled Breast Implant; Ideal Implant Incorporated, Irving, Texas) was developed to overcome the limitations of single-lumen saline implants by controlling saline movement and providing internal support to the implant edge and upper pole. The authors report 2-year data from a 10-year US clinical trial evaluating the safety and effectiveness of this investigational implant. Women seeking primary breast augmentation or replacement of existing augmentation implants were enrolled between February 2009 and February 2010 at 35 private practice sites, where the women underwent surgery to receive the new technology implant. Data collection included incidence and grade of capsular contracture (CC) and wrinkling as well as patient- and surgeon-reported satisfaction measures. All clinical data were reported as Kaplan-Meier risk rates of first occurrence, per patient, in each cohort. Two-year follow-up visits were completed by 472 of 502 enrolled women (94.0%), 378 of whom had undergone primary breast augmentation and 94 of whom had received replacement augmentation. Patient-reported satisfaction with the outcome was 94.3% for primary augmentations and 92.3% for replacement augmentations; surgeon-reported satisfaction was also high (96.5% and 93.4%, respectively). Baker Grade III and IV CC rates were 3.8% (primary) and 8.2% (replacement), whereas moderate-to-severe wrinkling was 3.8% (primary) and 12.0% (replacement). Deflations occurred in 4.8% of primary augmentations and 3.3% of replacement augmentations. No deflations were caused by a shell fold flaw. Two-year data from 472 women indicate that this double-lumen saline implant containing a baffle structure has a low rate of wrinkling and a lower rate of CC at 2 years than was reported for current single-lumen saline implants at 1 year.

    Full Text Available Objective: Pulmonary arterial hypertension (PAH is a rare but severe complication of connective tissue diseases (CTD, with a negative impact on patients survival. Bosentan, a receptor antagonist of endothelin, has been proved effective for the treatment of PAH. The aim of this study was to evaluate the effects and the safety of bosentan administered for 2 years in a group of patients with PAH related to CTD. Methods: Twelve patients with PAH related to systemic sclerosis (8 cases, SLE (2 cases, mixed connective tissue disease (1 case and polymyositis (1 case attending the Rheumatology Unit of Padova University were treated with bosentan for two years. Distance walked in 6 minutes, right ventricular systolic pressure and mean pulmonary artery pressure estimated by doppler echocardiography were evaluated at baseline and after 6, 12, 18 and 24 months of treatment. Safety was assessed by laboratory tests performed every two months. Results: During bosentan treatment, a significant decrease of right ventricular systolic pressure was observed after 6, 12, 18 and 24 months in comparison to baseline, whereas pulmonary artery mean pressure remained unchanged. Distance walked in 6 minutes slightly increased after 6 and 12 months, but significantly decreased after 18 and 24 months, mostly because complications of CTD which compromised the ability to walk arose in 4 patients. Adverse events related to bosentan were observed in 2 cases. Conclusions: Bosentan has been demonstrated effective in reducing pulmonary arterial pressure in a two-year period of treatment. Exercise capacity improved only in the first year of therapy and worsened thereafter, suggesting the opportunity of a combination therapy for a long-term treatment of PAH related to CTD.

    Full Text Available Background/Aim. Atopic diseases such as atopic dermatitis, allergic rhinitis and asthma have had increased prevalence during the past decade and nowadays occur in every third child in developed countries. The aim of the study was to determine frequency and type of atopic diseases at the age of two, as well as the importance the total IgE antibodies concentrations have in diagnosis and prognosis of the disease. Methods. The study involved 175 children up to two years of age. Allergy-like symptoms were found after surveying their parents and pediatric medical records. Using the fluorescence immunossay (FIA method, total IgE antibodies concentrations and specific IgE antibodies (Phadiatop infant were determined on an Immunocap 100 Dyagnostic System. Results. One or more allergy-like symptoms accounted for 57.7% of findings in children under the age of two, whilst in 19.4% the existence of IgE-related allergic diseases was found. Atopic diseases usually have clinical manifestations of atopic dermatitis (11.4%, IgE-bound wheezing/asthma (10.8% and food allergies (7.4%, and to much lesser extent those of allergic rhinitis (3.4% and urticaria (1.7%. The significantly higher total IgE antibodies concentrations were found in children with allergy-like symptoms (p < 0.0005 (cut-off 15.15 kU/L, sensitivity 76.5% specificity 71.6%. Conclusion. Almost 20% of two-year-old children have any of clinically manifested allergic diseases, with atopic dermatitis and IgE wheeze/asthma being predominant. The higher total IgE antibodies concentration is a good marker for sensitization in children with allergy-like symptoms.

    To evaluate the reliability and accuracy of computer-designed surgical guides in osseointegrated oral implant rehabilitation. Six implant rehabilitations, with a total of 17 implants, were completed with computer-designed surgical guides, performed with the master model developed by muco-compressive and muco-static impressions. In the first case, the surgical guide had exclusively mucosal support, in the second case exclusively dental support. For all six cases computer-aided surgical planning was performed by virtual analyses with 3D models obtained by dental scan DICOM data. The accuracy and stability of implant osseointegration over two years post surgery was then evaluated with clinical and radiographic examinations. Radiographic examination, performed with digital acquisitions (RVG - Radio Video graph) and parallel techniques, allowed two-dimensional feedback with a margin of linear error of 10%. Implant osseointegration was recorded for all the examined rehabilitations. During the clinical and radiographic post-surgical assessments, over the following two years, the peri-implant bone level was found to be stable and without appearance of any complications. The margin of error recorded between pre-operative positions assigned by virtual analysis and the post-surgical digital radiographic observations was as low as 0.2mm. Computer-guided implant surgery can be very effective in oral rehabilitations, providing an opportunity for the surgeon: (a) to avoid the necessity of muco-periosteal detachments and then (b) to perform minimally invasive interventions, whenever appropriate, with a flapless approach.

    2016-03-01

    Full Text Available Abstract Objective: To compare the functional performance of students diagnosed with developmental delay (DD up to two years of age with peers exhibiting typical development. Methods: Cross-sectional study with functional performance assessment of children diagnosed with DD up to two years of age compared to those with typical development at seven to eight years of age. Each group consisted of 45 children, selected by non-random sampling, evaluated for motor skills, quality of home environment, school participation and performance. ANOVA and the Binomial test for two proportions were used to assess differences between groups. Results: The group with DD had lower motor skills when compared to the typical group. While 66.7% of children in the typical group showed adequate school participation, receiving aid in cognitive and behavioral tasks similar to that offered to other children at the same level, only 22.2% of children with DD showed the same performance. Although 53.3% of the children with DD achieved an academic performance expected for the school level, there were limitations in some activities. Only two indicators of family environment, diversity and activities with parents at home, showed statistically significant difference between the groups, with advantage being shown for the typical group. Conclusions: Children with DD have persistent difficulties at school age, with motor deficit, restrictions in school activity performance and low participation in the school context, as well as significantly lower functional performance when compared to children without DD. A systematic monitoring of this population is recommended to identify needs and minimize future problems.

    2016-08-01

    Full Text Available BACKGROUND Multinodular goitre or nodular hyperplasia or adenomatoid goitre is the most common thyroid disease, which occurs due to deficient iodine intake. Initial hyperthyroid states, followed by follicular atrophy and secondary changes like haemorrhage, calcification and cystic degeneration occurs in most of the cases. Longstanding cases of nodular goitre can be associated with carcinomas, usually follicular carcinomas, and rarely papillary carcinomas.[1] This study was done to know the incidence of coexisting malignancies, follicular and papillary carcinomas of thyroid, in longstanding nodular goitres of thyroid. METHODS All the cases of nodular goitres examined in the last two years were studied, including the thyroidectomy specimens and FNAC slides whichever was done. Extensive grossing of the thyroidectomy specimens was done to detect the possibility of malignancy in longstanding cases of nodular goitre of thyroid. Review of FNAC slides was done in cases where cytodiagnosis of coexisting malignancy was missed and detected in histopathological examination. RESULTS In the present study, conducted over a two-year period, out of 50 cases of thyroidectomy specimens of multinodular goitres studied, six cases were diagnosed to be having coexisting malignancy of thyroid, of which four were follicular carcinomas of thyroid and two were papillary carcinomas of thyroid. FNAC diagnosis of coexisting malignancy was initially missed in FNAC in two cases, i.e. one case each of follicular carcinoma and papillary carcinoma. These FNAC slides were reviewed and the foci of malignancies detected. CONCLUSION There is a possibility of malignancy of thyroid coexisting with longstanding multinodular goitre of thyroid, which should be kept in mind, while performing the needle biopsy and thorough examination of FNAC slides is needed to avoid missing the possible detection of the coexisting malignant lesion. Thyroidectomy specimens should be extensively grossed to

    2012-01-01

    A synthesis of multiple coastal morphodynamic research efforts is presented to identify the processes responsible for persistent erosion along a 1-km segment of 7-km-long Ocean Beach in San Francisco, California. The beach is situated adjacent to a major tidal inlet and in the shadow of the ebb-tidal delta at the mouth of San Francisco Bay. Ocean Beach is exposed to a high-energy wave climate and significant alongshore variability in forcing introduced by varying nearshore bathymetry, tidal forcing, and beach morphology (e.g., beach variably backed by seawall, dunes, and bluffs). In addition, significant regional anthropogenic factors have influenced sediment supply and tidal current strength. A variety of techniques were employed to investigate the erosion at Ocean Beach, including historical shoreline and bathymetric analysis, monthly beach topographic surveys, nearshore and regional bathymetric surveys, beach and nearshore grain size analysis, two surf-zone hydrodynamic experiments, four sets of nearshore wave and current experiments, and several numerical modeling approaches. Here, we synthesize the results of 7 years of data collection to lay out the causes of persistent erosion, demonstrating the effectiveness of integrating an array of data sets covering a huge range of spatial scales. The key findings are as follows: anthropogenic influences have reduced sediment supply from San Francisco Bay, leading to pervasive contraction (i.e., both volume and area loss) of the ebb-tidal delta, which in turn reduced the regional grain size and modified wave focusing patterns along Ocean Beach, altering nearshore circulation and sediment transport patterns. In addition, scour associated with an exposed sewage outfall pipe causes a local depression in wave heights, significantly modifying nearshore circulation patterns that have been shown through modeling to be key drivers of persistent erosion in that area.

    The management of beaches that suffer from sediment deficit and construction of nearshore infrastructure in locations with intense sediment transit require adequate predictions of the future of the relevant sedimentary systems. To a large extent, this task can be accomplished by using jointly the information about sediment texture and long-term changes in the dry beach volume and the location of the waterline. It is straightforward to evaluate relative changes in the dry beach volume from a succession of airborne laser scanning (ALS) surveys. We use in addition terrestrial laser scanning (TLS) technique to reduce ALS surveys performed with different devices and from different height to the same absolute height. This is accomplished using a TLS survey of a large horizontal surface of constant elevation within ALS snapshots. The most complicated, time-consuming and expensive task in beach management and planning of nearshore infrastructure is to get an adequate picture of the intensity and direction of underwater sediment transport processes. We demonstrate how a simple application of so-called inverse Bruun Rule makes it possible to evaluate the underwater volumetric changes for almost equilibrium beaches. The approach requires three data sets: wave statistics, sediment texture and changes in the average position of the waterline. The main properties of the wave climate, closure depths, magnitude and direction of wave-driven alongshore transport near the test areas are established using a triple nested high-resolution version of the wave model WAM that is forced for 34 years by high-quality marine winds. The relocation of the waterline is extracted from the ALS scanning of elevation isolines of 0.4-0.7 m on the subaerial beach. The technique has been applied to two basically different sections of Tallinn Bay, the Baltic Sea. Pirita Beach is gradually losing sand and requires beach refill while a moderate reclamation action is planned in the vicinity of gradually

    Anthropogenic beach debris was recorded during beach surveys of 24 Caribbean islands during April 2014-April 2016. Beach debris was classified according to material type (e.g., polystyrene) and item use (e.g., fishing). Geophysical features (substrate type, beach direction, and human accessibility) of sample sites were recorded in order to investigate their relationship with debris density. Results suggest the density of macro debris (items >5mm) is highest on uninhabited, sandy beaches facing a leeward direction. Higher debris quantities on inaccessible beaches may be due to less frequent beach clean ups. Frequently accessed beaches exhibited lower macro, but higher micro debris (items 1-5mm) densities, possibly due to removal of macro debris during frequent beach clean ups. This suggests that while geophysical features have some influence on anthropogenic debris densities, high debris densities are occurring on all islands within the Caribbean region regardless of substrate, beach direction, or human accessibility.

  3. Brazilian sandy beach macrofauna production: a review

    Directory of Open Access Journals (Sweden)

    Marcelo Petracco

    2012-12-01

    Full Text Available The state of the art of the studies on the production of Brazilian sandy beach macrofauna was analyzed on the basis of the data available in the literature. For this purpose, the representativeness of the production dataset was examined by latitudinal distribution, degree of exposure and morphodynamic state of beaches, taxonomic groups, and methods employed. A descriptive analysis was, further, made to investigate the trends in production of the more representative taxonomic groups and species of sandy beach macrofauna. A total of 69 macrofauna annual production estimates were obtained for 38 populations from 25 studies carried out between 22º56'S and 32º20'S. Production estimates were restricted to populations on beaches located on the southern and southeastern Brazilian coast. Most of the populations in the dataset inhabit exposed dissipative sandy beaches and are mainly represented by mollusks and crustaceans, with a smaller number of polychaetes. The trends in production among taxonomic groups follow a similar pattern to that observed on beaches throughout the world, with high values for bivalves and decapods. The high turnover rate (P/B ratio of the latter was due to the presence of several populations of the mole crab Emerita brasiliensis, which can attain high values of productivity, in the dataset. Most of the studies focus on the comparison of production and, especially, of P/B ratio according to life history traits in populations of the same species/taxonomic group. Despite the importance of life history-production studies, other approaches, such as the effect of man-induce disturbances on the macrofauna, should be undertaken in these threatened environments.O estado da arte dos estudos de produção da macrofauna de praias arenosas brasileiras foi analisado a partir de informações disponíveis na literatura.

    The geomorphological evolution of a low-lying, micro-tidal sandy beach in the western Mediterranean, Pals beach, was characterized using airborne Light Detection and Ranging (LiDAR) data. Data were collected in prior to and six months after the impact of an extreme storm with a return period of approx. 50 years, with the aim of characterizing the beach's response to the storm. The use of repeated high-resolution topographic data to quantify beach geomorphic changes has allowed assessment of the accuracy of different proxies for estimating beach volume changes. Results revealed that changes in the shoreline position cannot accurately reproduce beach volume changes on low-lying beaches where overwash processes are significant. Observations also suggested that volume estimations from beach profiles do not accurately represent subaerial volume changes at large profile distances on beaches with significant alongshore geomorphological variability. Accordingly, the segmentation of the beach into regularly spaced bins is proposed to assess alongshore variations in the beach volume with the accuracy of the topographic data. The morphological evolution of Pals beach during the study period showed a net shoreline retreat (- 4 m) and a significant sediment gain on the subaerial beach (+ 7.5 m3/m). The net gain of sediment is mostly due to the impact of the extreme storm, driving significant overwash processes that transport sediment landwards, increasing volume on the backshore and dunes. The increase of volume on the foreshore and the presence of cuspate morphologies along the shoreline also evidence post-storm beach recovery. Observed morphological changes exhibit a high variability along the beach related to variations in beach morphology. Changes in the morphology and migration of megacusps result in a high variability in the shoreline position and foreshore volume changes. On the other hand, larger morphological changes on the backshore and larger inundation distances

    2005-01-01

    The littoral fauna of Maltese sandy and shingle beaches is generally regarded as impoverished and consequently of little conservation interest. The fauna of three sandy and three shingle beaches was systematically sampled by coring, standardised searching and pitfall traps. Diversity and population density were highest at the surface for sandy beaches, but were highest below the surface for shingle. The two beach types had distinct suites of species and individual beaches were faunistically d...

  6. Mechanical grooming and beach award status are associated with low strandline biodiversity in Scotland

    Science.gov (United States)

    Gilburn, Andre S.

    2012-07-01

    Beach grooming and beach award status are both shown to be associated with low macroinvertebrate taxon richness in Scotland. Previous studies in California have revealed that mechanical raking to remove wrack from sandy beaches has negative ecological consequences for coastal ecosystems. In the current study the presence and absence of eight common taxa that inhabit beached wrack on sandy beaches in Scotland was assessed at 60 sites, 24 of which were groomed and 29 of which were in receipt of a beach award. On average 4.86 of the eight taxa were found to be present on ungroomed beaches, whereas only 1.13 taxa were present on groomed beaches. Thus, beach grooming seems to be having a major effect on the biodiversity of beach macroinvertebrates in Scotland. Fewer macroinvertebrate taxa were also found on award (1.5) compared to non-award (4.38) beaches. It was also revealed that award beaches were much more likely to be groomed than non-award beaches, with 69% of award beaches surveyed being groomed compared to only 6% of non-award beaches. This pattern is surprising as the awarding bodies discourage the removal of seaweed and regulations state that beached wrack should only be removed if it constitutes a nuisance. It is concluded that award status, not nuisance level, has the main factor driving most beach grooming and that this has resulted in the substantial loss of macroinvertebrate biodiversity from award beaches in Scotland. In conclusion it is shown that beach grooming has a substantial negative impact upon strandline macroinvertebrate biodiversity in Scotland and that grooming is much more likely to occur on award beaches.

    Two-year colleges (2YCs) play a critical role in geoscience education in the United States. Nearly half of the undergraduate students who take introductory geoscience do so at a 2YC. With awide reach and diverse student populations, 2YCs may be key to producing a well-trained, diverse and sufficiently large geoscience workforce. However, faculty at 2YCs often face many barriers to professional development including lack of financial resources, heavy and inflexible teaching loads, lack of awareness of opportunities, and few professional development resources/events targeted at their needs. As an example, at the 2009 GSA meeting in Portland, fewer than 80 of the 6500 attendees were from community colleges, although this was more than twice the 2YC faculty attendance the previous year. Other issues include the isolation described by many 2YC geoscience faculty who may be the only full time geoscientist on a campus and challenges faced by adjunct faculty who may have even fewer opportunities for professional development and networking with other geoscience faculty. Over the past three years we have convened several workshops and events for 2YC geoscience faculty including technical sessions and a workshop on funding opportunities for 2YC faculty at GSA annual meetings, a field trip and networking event at the fall AGU meeting, a planning workshop that examined the role of 2YCs in geoscience education and in broadening participation in the geosciences, two workshops supporting use of the 'Math You Need, When You Need It' educational materials that included a majority of 2YC faculty, and marine science summer institutes offered by COSEE-Pacific Partnerships for 2YC faculty. Our experience indicates that 2YC faculty desire professional development opportunities when the experience is tailored to the needs and character of their students, programs, and institutions. The content of the professional development opportunity must be useful to 2YC faculty -workshops and

  8. Radiological and migration results of the DURALOC(R)-cup after two years

    2000-10-01

    In 1997 a study was conduced concerning 69 consecutive patients, all of whom consisted of DURALOC(R) series 100 acetabular components. The clinical, radiological and migrational aspect of each component was investigated 2 and 4 years postoperatively. In addition to this, a further 92 cups were analyzed in an identical manner, again 2 years after implantation. This therefore equated to a total of 161 investigated cups after a follow up interval of 2 years. In 144 of these cases the cup was combined with a cementless hydroxyapatite coated Spotorno shaft, with the remaining 17 involving a cemented Link-shaft (Lubinus SP II). A 28 mm Biolox(R) ceramic head was constant in all cases. Clinical data for each cup was collected via completion of a standard examination form, while acetabular migration, both vertical and horizontal, was measured on serial radiographs by the computer assisted EBRA method. From analyses of collected data, it was clearly shown that the clinical results remained very good over the 2- and 4-year-periods however, from radiological evidence it was indicated that for the period 3-4 years postoperatively, an increasing amount of radiolucencies around the cups were apparent. There was clearly no correlation between clinical and migration results. From the data taken from 106 migration curves, the mean total migration over the initial two-year-period was calculated to be 0.88 mm. From analysis of a further 56 migration curves, the mean total migration within 4 years of implantation was assessed to be 1.23 mm, however a decreasing speed of migration over the final 2-year-period was indicated. Our results demonstrate that statements relating to migration results of particular cups are more accurate after four years. However, statements about mean migration values are possible after two years. A migration speed of 1 mm total migration within the first 2 years after operation was predictive for radiological loosening of the cup after four years (p=0

    Dunes act as an indispensable natural safety barrier against marine flooding, are valuable natural environments, serve for the production of drinking water, and offer recreational opportunities. The safety function has dominated dune management in the Netherlands, as well as on other developed shores, for decades. Measures to minimize the seaward loss of foredune sand under storm wave attack have resulted in over-stabilized foredunes and, accordingly, have impoverished natural beauty and degraded biodiversity. Stabilized foredunes are nowadays increasingly reactivated by removing vegetation and by digging trenches that resemble natural trough blowouts as corridors for aeolian transport from the beach into the backdunes. Crucially, such measures see the beach-dune system as an integrated landscape, reconnecting the beach, foredune and backdunes through aeolian transport. This raises questions on how much sand is actually blown into the dunes, which factors affect this amount, and how effective the large-scale dune-restoration measures are. This contribution addresses the evolution of five trenches that were dug through the 20-m high foredune at the Dutch National Park Zuid-Kennemerland. The width of the trenches was 50 - 100 m, their cross-dune length was 60 - 100 m, and the heighest part of the valley floor was 9 m above mean sea level. Since their construction in the 2012/2013 winter the trenches have been surveyed approximately 3 times per year using airborne laser scanning or UAV photography, resulting in a multi-temporal data set of Digital Elevation Models (DEMs) with a 1x1 m resolution. Difference maps illustrate that the sidewalls of the trenches have steepened during the first two years after construction, but that their width and the height of the valley floor have remained largely unaltered. Landward of the trenches large sedimentation lobes have formed, which with time have grown both laterally and vertically. Locally, the lobe thickness now exceeds 5 m

    Marine debris is widely distributed at the coastal area of the global oceans; however, shipborne garbage source studies are still lacking to document the pollution in Malaysia Territorial Water. Thus, this study has adopted a standard method of beach marine debris survey at five beaches and inspected 115 vessels to assess the type and amount of debris from shipping source stranded on the beach. This study found that vessel visiting Malaysian ports observed the MARPOL 73/78 Annex V requirements; however, identified objects from shipping activity (1.3%; 2 items/km) found on the beaches indicate that there are vessels disposing of garbage illegally at sea. Therefore, there is a need to promote the use of biodegradable material and introduce environmental education to increase awareness on the vessel.

Observations of bathymetry, sediment properties and sources, sediment transport processes and their changes arising from coastal engineering activities are reported. The mean grain size is about 0.12 mm, with the fine sand fraction (0.063–0.125 mm accounting for about 77% of the sediments. Coarse sand dominates only along the waterline. The content of coarser sediments is greater in the northern part of the beach. A number of coastal engineering structures have blocked natural sediment supplies. The beach suffers from sediment deficit now and has lost about 400 m3 of sand annually from the dry beach between 1997 and 2005.

    Full Text Available Although rare, malignant melanoma may occur in children. Childhood melanomas account for only 0.3–3% of all melanomas. In particular the presence of congenital melanocytic nevi is associated with an increased risk of development of melanoma. We herein report a case of malignant melanoma that developed on a giant congenital melanocytic nevus and made a metastasis to the subcutaneous tissue of neck in a two-year-old girl. The patient was hospitalized for differential diagnosis and treatment of cervical mass with a suspicion of hematological malignancy, because the malignant transformation of congenital nevus was not noticed before. In this case, we found out a nonpigmented malignant tumor of pleomorphic cells after the microscopic examination of subcutaneous lesion. Nonpigmented metastatic melanoma was diagnosed by several immunohistochemical and flow cytometric studies. She was offered palliative chemotherapy; however, her parents did not accept treatment. The patient died within 9 months of diagnosis. We emphasized here that the possibility of malignant melanoma in the differential diagnosis of childhood tumors should be kept in mind.

    In November 1980, Westinghouse Hanford Company installed the initial version of the Safeguards Active Response Inventory System (SARIS). It was designed as an advanced accountability system to meet the needs of process, safeguards, criticality, safety, and inventory control. A single database translates information about a quantity of nuclear material into the language used by process operators or accountants. Modifications made through functions that model the process automatically generate changes in nuclear material reports, including input of transactions to the NMMSS system at Oak Ridge, Tennessee. During the past two years, the user attitude about SARIS has improved, largely due to the changes implemented in four major additions. Problems encountered during development include: obtaining accurate and complete data to load the database, slow computer response, insufficient communication between users and developers, insufficient training of users before system implementation, and functions that did not exactly meet the user's needs. The benefits of SARIS have included: consistency in data reporting, fewer errors due to immediate resolution of discrepancies, a standardized audit trail, and elimination of manual methods. The most important improvement is a reporting scheme that enables rapid conduction and reconciliation of physical inventories

  7. Stormwater Treatment Evaluation of a Constructed Floating Wetland after Two Years Operation in an Urban Catchment

    2017-09-01

    Full Text Available Constructed Floating Wetlands (CFW for stormwater treatment are increasingly used to treat urban runoff. However, studies of large-scale systems and the long-term evaluation of their treatment efficiency are scarce. This article presents the final results of a two-year study of the pollutant removal performance of a CFW in a stormwater pond capturing runoff from a low-residential catchment in South-East Queensland (Australia under subtropical conditions. Although the CFW treatment area to catchment ratio was only 0.14%, the results demonstrated a significant removal of both Total Suspended Solids (TSS and Total Phosphorus (TP from the stormwater inflows by the CFW. The efficiency ratios for TSS and TP were 81% and 52%, respectively. While the removal rate for total nitrogen was not significant for the CFW evaluated in this study, the ER was still 17%. However, the ERs for nitrate and nitrogen oxide were both 47%. The study results suggest that it may be possible to increase the pollution removal performance of the CFW by upsizing the system and including intermittent re-aeration zones in the surrounding stormwater pond. The results of this research study clearly demonstrate that CFW can be an effective treatment solution for the removal of pollution from urban stormwater runoff.

    UTEP-ROCCS (Research Opportunities for Community College Students) is a summer REU program designed exclusively for two-year college students. The program differs from other summer REU's in several ways. First, the participants are only in El Paso during the month of June to begin their research projects, with subsequent research carried out at their home institutions with intensive virtual mentoring in July. Second, the mentoring team is a unique mix of 2-year and 4-year college faculty and undergraduate juniors and seniors. Our first cohort of 6 ROCCS students began their research in June 2017 supported by 2 UTEP undergraduate mentors and 5 faculty mentors. Preliminary results of a series of 4 weekly road checks indicate that 95% of the time the participants felt the faculty and student mentors were supportive, encouraging, and able to respond to their questions and concerns. All felt they received constructive, useful critiques of their field and research work, were motivated by the mentors to learn more and were challenged to extend their abilities and skills for the success of their research projects. Over 70% of the time they felt the mentors encouraged them by suggesting appropriate and available resources when they were struggling. And, most importantly, over 96% of the time they felt the experience stimulated their interest in geology as a future career. We hope to observe similar trends in the road checks of July 2017 as participants prepare their results for the AGU's fall virtual undergraduate poster session.

    This research explored the relative impact of demographic, cognitive, behavioural, and psycholinguistic factors on vocabulary development in two-year-old children. Two hundred and thirty-two children (24-30 months) were tested on expressive and receptive vocabulary, cognitive development, word learning and working memory skills. Parents completed a British adaptation (Klee & Harrison, 2001) of the MacArthur-Bates Communicative Development Inventory (CDI; Fenson et al., 1993), a demographic questionnaire and a questionnaire regarding the child's social-emotional behaviour. Several demographic, child and processing variables were significantly correlated with CDI (vocabulary) scores, but the only significant unique predictors of CDI scores were nonword repetition (NWR; R(2) change = .36), sex (R(2) change = .05) and age (R(2) change = .04). Scores were only included when a child completed the entire NWR test (77% of toddlers). The NWR task used in this experiment maximised participation in this group of toddlers, and was a strong predictor of vocabulary ability. Longitudinal research is warranted to explore the independent and reciprocal growth in working memory and language skills in children.

    The Trialog project offers patients with early-onset schizophrenia (EOS) a two-year programme of residential outpatient care following discharge from a clinic. The programme aims to support their further recovery and independence and encompasses interactive and psycho-educational multifamily care, coping with persistent symptoms, development of socio-emotional competence, independent house keeping, and support of school and vocational training. To evaluate psychopathology along with social and neuropsychological function for 12 participants over a period of 2 years. Their progress was compared with that of 12 EOS patients who did not attend Trialog following discharge. Participants showed a significantly greater decrease of positive and negative symptoms, as opposed to an increase in positive symptoms in the comparison group. Measures of social function, neuropsychological indicators of memory, (selective) attention, and psychomotor speed improved more than in the comparison subjects. Neither group showed changes in measures of intelligence or in the subjective quality of life. First analyses raise hope that monitoring participant performance in the programme of the "Trialog project" will improve the treatment and care of EOS-patients in the critical first years following the onset of schizophrenia.

    A majority of states now restrict teenagers from using a mobile communication device while driving. The effect of these restrictions is largely unknown. In a previous study, we found North Carolina's teenage driver cell phone restriction had little influence on young driver behavior four months after the law took effect (Foss et al., 2009). The goal of the present study was to examine the longer-term effect of North Carolina's cell phone restriction. It was expected that compliance with the restriction would increase, as awareness of the restriction grew over time. Teenagers were observed at high schools in North Carolina approximately two years after the law was implemented. Observations were also conducted in South Carolina, which did not have a cell phone restriction. In both states, there was a broad decrease in cell phone use. A logistic regression analysis showed the decrease in cell phone use did not significantly differ between the two states. Although hand-held cell phone use decreased, there was an increase in the likelihood that drivers in North Carolina were observed physically manipulating a phone. Finally, a mail survey of teenagers in North Carolina showed awareness for the cell phone restriction now stands at 78% among licensed teens. Overall, the findings suggest North Carolina's cell phone restriction has had no long-term effect on the behavior of teenage drivers. Moreover, it appears many teenage drivers may be shifting from talking on a phone to texting. Copyright © 2012 Elsevier Ltd. All rights reserved.

  12. Engaging College Students at Two-year Campuses in Aerospace Research

    College students at two-year campuses have unique challenges to their learning and are often "nontraditional" students, including first-generation and/or returning adult students. They have little or no exposure to research, related to science and aerospace or otherwise, and so they do not think of these fields as possible careers or understand how the disciplines operate. Exposing these students to real research projects, especially ones that include rocket payloads, have a dramatic effect on the interests and academic success of students. Projects such as these can be quite large and expensive, perhaps prohibitively so for small institutions. We engaged a group of these students through the RockOn and RockSat programs lead by the Colorado Space Grant Consortium, which are programs for postsecondary students to access space with relatively easy access and low cost. The student team designed, built, and flew a scientific payload on a suborbital sounding rocket launched at NASA's Wallops Flight Facility in Virginia. The experiment sent E. coli DNA samples into space to assess the damage and measured the radiation exposure with and without radiation shielding, and assessed the samples for DNA damage upon their return. We report on the process and the effects on the students as part of their experience.

    1994-10-01

    This is a two year retrospective analysis of 1,260 live single births at Sidamo Regional Hospital during 1989-1990. The mean birth weight was 3,243 g (SD +/- 625). There were 678(53.8%) boys and 582(46.2%) girls. The mean birth weight for boys and girls were 3,324 g (SD +/- 622) and 3147 g (SD +/- 611), respectively (t = 5.05; p < 0.001). There were significant correlations between birth weight and the age of the mother (r = 0.20; p < 0.001) as well as with parity (r = 0.15; p < 0.001). Eight per cent of the babies had birth weight less than 2,500 g. Five per cent of boys and 11% of girls had low birth weights (chi 2 = 8.8; p < 0.002). Higher proportion of low birth weight was also found among the young and primiparous mothers. A multiple linear regression analysis showed a significant and independent effect of maternal age and sex of the baby on birth weight. The findings are in general agreement with previous studies from Ethiopia and other developing countries. However, as this study is based on hospital data, community-based studies are needed to examine the true pattern of birth weights as hospital data may be biased.

    Crandall, Elizabeth Diane

    This dissertation identified the cognitive levels of lecture objectives, lab objectives, and test questions in introductory majors' biology. The study group included courses offered by 27 faculty members at 18 of the 22 community colleges in Arkansas. Using Bloom's Taxonomy to identify cognitive levels, the median lecture learning outcomes were at level 2 (Comprehension) and test assessments at Level 1 (Knowledge). Lab learning outcomes were determined to have a median of level 3 (Analysis). A correlation analysis was performed using SPSS software to determine if there was an association between the Bloom's level of lecture objectives and test assessments. The only significant difference found was at the Analysis level, or Bloom's level 4 (p=.043). Correlation analyses were run for two other data sets. Years of college teaching experience and hours of training in writing objectives and assessments were compared to the Bloom's Taxonomy level of lecture objectives and test items. No significant difference was found for either of these independent variables. This dissertation provides Arkansas two-year college biology faculty with baseline information about the levels of cognitive skills that are required in freshman biology for majors courses. It can serve to initiate conversations about where we are compared to a national study, where we need to be, and how we get there.

    This study provides prospective, longitudinal data on the relationship between stress-related measures and academic performance during the first two years of medical school. First year medical students (n = 121) were surveyed prior to beginning classes (wave 1), and again 8 months later (wave 2). Personality variables predisposing to distress (optimism and trait anxiety), stress response (depression and state anxiety), and stress management strategies were assessed at wave 1 and wave 2. Pre-medical academic scores, and grades at the end of five assessment periods over the course of the first 2 years of medical school were also obtained. As expected, pre-medical-school academic performance strongly predicted performance in medical school. Academic performance before and during medical school was negatively related to reported stress levels. On bivariate correlations, there were numerous significant relationships between stress reported at waves 1 and 2, and medical school academic performance assessed after these measures. In addition there were modest negative correlations between self-reported coping strategies of 'humour' and 'wishful thinking', and consequent academic performance. However, the predictive value of stress and its management on prospective academic performance was much decreased once pre-medical-school performance was statistically controlled.

    Full Text Available Introduction: Trauma to the facial region causes injuries to hard and soft tissues of the face. Injuries to the maxillofacial region are increasing in frequency and severity because of the increased number of road traffic accidents (RTAs and increased number of violence. The purpose of this study was to evaluate age, gender distribution, etiology, and pattern of mandibular fractures in Western part of Maharashtra population. Materials and Methods: The study was conducted in the Department of Oral Medicine and Radiology for a period of two years from June 2013 to June 2015. Clinical examination of all trauma patients was done and diagnosis was made based on signs, clinical features, and confirmed by orthopantomographs. Results: Totally, 193 patients were detected with different types of mandibular fractures. Study group involved 77.2% males and 22.8% females with a male to female ratio of 3.3:1. Majority of patients were in the age group of 21–30 years followed by 31–40 years. Trauma due to RTAs were more common followed by assaults and fall. Parasymphyseal fractures were most common type followed by condylar fracture and fracture of angle of mandible. Conclusion: Males were most commonly affected by trauma than females with a predominant age group of 21–30 years. Majority of trauma were due to RTAs with parasymphyseal as most common type of fracture.

    Full Text Available The article summarizes a two-year experience of treating children and adolescents with severe uncontrolled atopic asthma using Omalizumab. This treatment facilitated to achieve full asthma control in 70% of patients and partial control in 30% of patients. Anti-Ig Etherapy contributes to reduce the frequency of asthma relapses 77%, and the number of those seeking emergency medical treatment, particularly no need for in-patient asthma care. Thanks to treatment, lung function parameters improve, particularly in children with low bronchial patency parameters even after administration of broncholytics. Thanks to treatment with omalizumab, the dosage of inhalant glucocorticosteroids is reduced 1.5 to 2.5 times in 75% patients. Treatment tolerance in all children is satisfactory, no serious adverse events associated with the medication or any system side effects are registered in patients. Anti-IgE therapy is a good alternative to use of high and ultra-high doses of inhalant glucocorticosteroids in children with severe atopic asthma.

    In the field of anesthesia for bariatric surgery, a wide variety of recommendations exist, but a general consensus on the perioperative management of such patients is missing. We outline the perioperative experiences that we gained in the first two years after introducing a bariatric program. The perioperative approach was established together with all relevant disciplines. Pertinent topics for the anesthesiologists were; successful airway management, indications for more invasive monitoring, and the planning of the postoperative period and deposition. This retrospective analysis was approved by the local ethics committee. Data are mean [SD]. 182 bariatric surgical procedures were performed (147 gastric bypass procedures (GBP; 146 (99.3%) performed laparascopically). GBP patients were 43 [10] years old, 78% female, BMI 45 [7] kg/m(2), 73% ASA physical status of 2. 42 patients (28.6%) presented with obstructive sleep apnea syndrome. 117 GBP (79.6%) patients were intubated conventionally by direct laryngoscopy (one converted to fiber-optic intubation, one aspiration of gastric contents). 32 patients (21.8%) required an arterial line, 10 patients (6.8%) a central venous line. Induction lasted 25 [16] min, the procedure itself 138 [42] min. No blood products were required. Two patients (1.4%) presented with hypothermia (bariatric patients demand a tailored approach from both the anesthesiologist and the perioperative team. The interaction of a multi-disciplinary team is key to achieving good outcomes and a low rate of complications. DRKS00005437 (date of registration 16(th) December 2013).

    The aim of the clinical study is to evaluate Er:YAG laser ablation after two year-long clinical treatment. One hundred fifty cavities were volunteered for checking. Three restorative materials were used following manufacturer's directions. For the experiment, an Er:YAG laser drilling machine was applied. The laser delivered energy from 100 to 450 mJ, repetition rate from 1 to 4 Hz. The length of the generated pulses was 200 microseconds. During our experiments cooling of the teeth was achieved by fine water mist. The number of pulses was from 16 to 489. Caries of enamel and dentin were treated. Old insufficient fillings were also removed (not amalgam or metal alloys). The experiments followed the guidelines of the Declaration of Helsinki (1964), Tokyo (1975), Venice (1983) and Hong-Kong (1989). Clinical evaluation of fillings after 6, 12, 18 and 24 months based on ADA recommendation was used. Eight criteria were applied for the restoration control. Composite resins and glassionomers could be used as filling materials.

    Full Text Available Introduction. Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. Objective. The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. Methods. Clinical study included 49 teeth indicated for endodontic retreatment based on periapical index (PAI. All teeth were divided into two groups. Group I comprised teeth without any periapical lesion (PAI score of 1 and 2 while Group II consisted of teeth with visible periapical radiolucency (PAI score of 3, 4, and 5. Endodontic retreatment was completed in two visits with inter-appointment medication of 2% chlorhexidine and calcium hydroxide for two weeks. Outcome of endodontic retreatment was evaluated 12-24 months after final obturation. Results. Endodontic retreatment was successful in 93.3% in Group I after 24 months. In Group II, successful treatment and complete healing was found in 52.9% of teeth, whereas 14.7% of teeth showed only partial healing. However, clinical symptomatology was not present in any of the cases. Considering the absence of clinical signs and subjective symptoms, retreatment was successful in 67.6% of cases where chronic periapical inflammation was present. Conclusion. Endodontic retreatment was successful in high percentage in teeth with and without periapical lesions.

    In November 1980, Westinghouse Hanford Company installed the initial version of the Safeguards Active Response Inventory System (SARIS). It was designed as an advanced accountability system to meet the needs of process, safeguards, criticality, safety, and inventory control. A single database translates information about a quantity of nuclear material into the language used by process operators or accountants. Modifications made through functions that model the process automatically generate changes in nuclear material reports, including input of transactions to the NMMSS system at Oak Ridge, Tennessee. During the past two years, the user attitude about SARIS has improved, largely due to the changes implemented in four major additions. Problems encountered during development include: obtaining accurate and complete data to load the database, slow computer response, insufficient training of users before system implementation, and functions that did not exactly meet the user's needs. The benefits of SARIS have included: consistency in data reporting, fewer errors due to immediate resolution of discrepancies, a standardized audit trail, and elimination of manual methods. The most important improvement is a reporting scheme that enables rapid conduction and reconciliation of physical inventories

    Separate collection of biodegradable garbage and recyclable waste is expected to become mandatory in some western countries. A growing number of persons engaged in garbage collection and separation might become endangered by high loads of bacteria and fungi. Case history and examination A 29 year old garbage collector involved in emptying so-called biological garbage complained of dyspnea, fever, and flu-like symptoms during work beginning in the summer of 1992. Chest x-ray showed streaky shadows near both hili reaching into the upper regions. IgE- and IgG-antibodies (CAP, Pharmacia, Sweden) were strongly positive for Aspergillus fumigatus with 90.5 kU/L and 186%, respectively. Total-IgE was also strongly elevated with 5430 kU/L. Bronchial challenge testing with commercially available Aspergillus fumigatus extract resulted in an immediate-type asthmatic reaction. Two years later he was still symptomatic and antibodies persisted at lower levels. Our diagnosis was allergic bronchopulmonary aspergillosis (ABPA) including asthmatic responses as well as hypersensitivity pneumonitis (extrinsic allergic alveolitis) due to exposure to moldy household waste. A growing number of persons engaged in garbage collection and handling are exposed and at risk to develop sensitization to fungi due to exposure to dust of biodegradable waste. Further studies are necessary to show if separate collection of biodegradable waste increases the health risks due to exposure to bacteria and fungi in comparison to waste collection without separation.

    Full Text Available Salman Rushdie’s memoirs, essays and novels contribute to the appreciation of the contradictions in his outlook on life. His experiences in his family enable Rushdie to make efforts for objective and tolerant judgement of British lifestyle and culture. However, his isolation from the society in Britain despite his struggle for adaptation to British cultural values cause contradictions in his cultural identity. While Rushdie expresses his allegiance to India and its culture in The Ground Beneath Her Feet (1999, he reflects his alienation from his homeland in this novel as well. Similarly, in his Imaginary Homelands (1981-1991 whereas Rushdie questions the injustice and inequality caused by imperialism in The New Empire within Britain (1982, he justifies the colonialist discourse in Kipling (1990. He elaborates on the contradictions in his outlook on life in terms of his cultural ambivalence in his fictions such as Midnight’s Children (1981 and Shame (1983. However, in his latest novel, Two Years, Eight Months and Twenty-Eight Nights (2015, Rushdie reflects his cultural identity conflict in terms of rationalism-mysticism dichotomy. With the use of allegory as well as the lack of linearity in time and space, Rushdie justifies his cultural ambivalence in relation to the dynamism of contemporary world. Thus, Rushdie’s latest novel invites reading for its representation of the oppositions in his approach to life.

    To make up for the lack of data on {sup 210}Pb aerosol deposition in tropical regions and to use this radionuclide as an aerosol tracer,a monitoring station was run for two years at Petit-Saut, French Guiana. Lead-210 concentration in air at ground level was monitored continuously together with atmospheric total deposition. The air concentration has a mean value of 0.23{+-}0.02 mBq m{sup -3} during both wet and dry seasons, and it is only weakly affected by the precipitation mechanism. This result was unexpected in a wet tropical region, with a high precipitation rate. In contrast, deposition clearly correlates with precipitation for low/moderate rainfall (<15 cm per 15-day), while this correlation is masked by strong fluctuations at high rainfall. The estimated mean annual deposition over the last ten years is 163{+-}75 Bq m{sup -2} y{sup -1}. This provides a procedure fo estimating this mean flux at other sites in French Guiana.

    We aimed at analyzing important predictive factors for experienced negative emotional and social effects of rheumatoid arthritis (RA) two years after diagnosis in patients aged 18-65 years. The first group included 41 participants, who had psychosocial problems (PSP) already at diagnosis, and who received an intervention by a medical social worker to improve coping capacity and social situation. The second group included 54 patients (NPSP) without such problems at diagnosis. All completed a questionnaire mapping their social situation, the Hospital Anxiety and Depression Scale (HADS), the Sense of Coherence Scale (SOC) and the General Coping Questionnaire (GCQ) at diagnosis and after 24 months. The most pronounced predictive factor for a strong impact of the disease was high scores on HADS depression scale. After 24 months, PSP participants had a more strained life situation, with higher scores on anxiety and depression and lower on SOC, in comparison with NPSP. NPSP participants improved their coping strategies regarding self-trust, cognitive revaluation, protest and intrusion, but deteriorated regarding problem focusing and social trust. PSP patients kept their initial coping strategies, except for intrusion decreasing over time, and seemed to have a more rigid coping pattern. However, the experienced negative impact of the disease increased over time in both groups despite improvement in sickness related data. Mostly influenced areas were economy, leisure time activities and social life. We conclude that psychosocial consequences of RA are more connected to emotional and social vulnerability than are RA-related clinical factors.

    2000-01-01

    4 years of implantation was assessed to be 1.23 mm, however a decreasing speed of migration over the final 2-year-period was indicated. Our results demonstrate that statements relating to migration results of particular cups are more accurate after four years. However, statements about mean migration values are possible after two years. A migration speed of 1 mm total migration within the first 2 years after operation was predictive for radiological loosening of the cup after four years (p=0,0004). Further, appearance of postoperative gaps in zone one of the cup correlate with high migration values later leading to radiological loosening and may be a result of errors during implantation. However, we could demonstrate that presence of gaps around the cup postoperatively is an important factor for later loosening. With consideration to the findings concerning the DURALOC(R) cup within four years of implantation, predictions of results over a long term may be undesirable. In 1997 a study was conduced concerning ...

    It is difficult to distinguish whether children's head injuries are due to physical abuse or unintentional accidents. However, in the literature, medical findings specific to infant physical abuse were identified. Thus, we developed diagnostic criteria for inflicted head injury (IHI) and assessed its validity. Subjects were collected from all patients who were less than two years old when they visited National Center for Child Health (NCCHD) and Development and underwent head CT scan to assess head trauma from March 1, 2002 to December 31, 2005. Diagnostic criteria for IHI were developed based on definitions of Duhaime et al (1992) and Reece et al (2001). Validity of diagnosis criteria was assessed by comparing the official report to the Child Guidance Center (CGC) from NCCHD to the disposition decided by the CGC. Two-hundred and sixty cases were collected and diagnosed. There was a 86.5% match of the number of cases which were diagnosed as IHI or non-IHI using the IHI diagnostic criteria with official reports to CGC from NCCHD. Among the cases which were diagnosed as presumptive IHI and also reported to the CGC, 20 cases (83.3%) were regarded as abused cases by the CGC. The diagnostic criteria for IHI were valid and would be useful for pediatricians not to condone inflicted head injury. (author)

    After five years of planning, equipment acquisition, facility construction and beam testing the Seattle Clinical Neutron Therapy facility became operational in October 1984. In the past two years nearly 300 people have been treated in clinical trials. During this time 82 % of the planned treatment sessions were performed on schedule, 3 % had to be rescheduled for patient related reasons and 15 % because of equipment problems. The facility is at present running on a 5 days/week schedule: Three ten-hour treatment days, one maintenance day and one research day (radiobiology, therapy related physics). Short runs for short lived isotopes are done between patient treatments. The isocentric gantry, capable of 360 rotation is equipped with a variable collimator with 40 independent leaves. This collimation system allows the use of complex field shapes without the necessity of handling radioactive components like collimator inserts or blocks. It has turned out to be a very essential part for the efficient operation of the facility. Major causes for equipment downtime were associated with the control system, the beryllium target system, RF and magnet systems and the treatment gantry. (author)

    Aspergillus niger. Tiegh., a filamentous ascomycete fungus, was isolated from the metal samples exposed to marine, rural and urban sites in Lithuania. Al and Zn samples were subjected to two-year influence of A. niger under laboratory conditions in humid atmosphere. Electrochemical impedance spectroscopy (EIS) ascertained microbially influenced corrosion acceleration (MICA) of Zn and inhibition (MICI) of Al. EIS data indicated a two-layer structure of corrosion products on Zn. The microorganisms reduced the thickness of the inner layer, whose passivating capacity was much higher when compared to that of the outer layer. An increase in aluminium oxide layer resistance but decrease in the layer thickness implied that MICI affected primarily the sites of localized corrosion of Al (pores, micro-cracks, etc.). X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) studies indicated that bioproducts (i.e. organic acids) did not form crystalline phases with corrosion products of zinc. The study suggested a hypothesis that microorganisms could be used as corrosion protectors instead of toxic chemicals, application of which tends to be increasingly restricted.

    Many studies have established that children tend to exclude objects for which they already have a name as potential referents of novel words. In the current study we asked whether this exclusion can be triggered by social-pragmatic context alone without pre-existing words as blockers. Two-year-old children watched an adult looking at a novel object while saying a novel word with excitement. In one condition the adult had not seen the object beforehand, and so the children interpreted the adult's utterance as referring to the gazed-at object. In another condition the adult and child had previously played jointly with the gazed-at object. In this case, children less often assumed that the adult was referring to the object but rather they searched for an alternative referent--presumably because they inferred that the gazed-at object was old news in their common ground with the adult and so not worthy of excited labeling. Since this inference based on exclusion is highly similar to that underlying the Principle of Contrast/Mutual Exclusivity, we propose that this principle is not purely lexical but rather is based on children's understanding of how and why people direct one another's attention to things either with or without language.

    Full Text Available Background. End-stage renal disease (ESRD patients under hemodialysis (HD have high mortality rate. Inflammation, dyslipidemia, disturbances in erythropoiesis, iron metabolism, endothelial function, and nutritional status have been reported in these patients. Our aim was to identify any significant association of death with these disturbances, by performing a two-year follow-up study. Methods and Results. A large set of data was obtained from 189 HD patients (55.0% male; 66.4 ± 13.9 years old, including hematological data, lipid profile, iron metabolism, nutritional, inflammatory, and endothelial (dysfunction markers, and dialysis adequacy. Results. 35 patients (18.5% died along the follow-up period. Our data showed that the type of vascular access, C-reactive protein (CRP, and triglycerides (TG are significant predictors of death. The risk of death was higher in patients using central venous catheter (CVC (Hazard ratio [HR] =3.03, 95% CI = 1.49–6.13, with higher CRP levels (fourth quartile, compared with those with lower levels (first quartile (HR = 17.3, 95% CI = 2.40–124.9. Patients with higher TG levels (fourth quartile presented a lower risk of death, compared with those with the lower TG levels (first quartile (HR = 0.18, 95% CI = 0.05–0.58. Conclusions. The use of CVC, high CRP, and low TG values seem to be independent risk factors for mortality in HD patients.

    The first two years of life is a crucially important period for the development of communication skills. In this study joint attention and language development were monthly assessed between 8 and 24 months of age in a sample of 23 typically developing children to establish the developmental trajectory of specific joint attention skills, to investigate the developmental interrelations of these different joint attention skills with vocabulary size, and to examine whether the order of development of following and directing attention influences the development of other early communication skills such as language. All joint attention skills emerged between 8 and 15 months of age and responsive joint attention skills tend to emerge before initiative joint attention. Early joint attention skills influenced later language development, but not the other way around. Children in whom directing attention with gaze alternation developed early (in age or order) showed a relatively larger early vocabulary growth. A fine grained mapping of the normal development of early communication skills can be helpful in the early detection of abnormalities in these skills. Copyright © 2012 Elsevier Inc.

  14. Results from Two Years of Ka-Band Propagation Characterization at Svalbard, Norway

    Over the several years, NASA plans to launch several earth science missions which are expected to achieve data throughputs of 5-40 terabits per day transmitted from low earth orbiting spacecraft to ground stations. The current S-band and X-band frequency allocations in use by NASA, however, are incapable of supporting the data rates required to meet this demand. As such, NASA is in the planning stages to upgrade its existing Near Earth Network (NEN) Polar ground stations to support Ka-band (25.5-27 GHz) operations. Consequently, it becomes imperative that characterization of propagation effects at these NEN sites is conducted to determine expected system performance, particularly at low elevation angles ((is) less than 10 deg) where spacecraft signal acquisition typically occurs. Since May 2011, NASA Glenn Research Center has installed and operated a Ka-band radiometer at the NEN site located in Svalbard, Norway. The Ka-band radiometer monitors the water vapor line, as well as 6 frequencies around 26.5 GHz at multiple elevation angles: 45 deg, 20 deg, and 10 deg. Two year data collection results indicate comparable performance to previously characterized northern latitude sites in the United States, i.e., Fairbanks, Alaska. It is observed that cloud cover at the Svalbard site remains the dominant loss mechanism for Ka-band links, resulting in a margin requirement of 4.1 dB to maintain link availability of 99% at 10 deg elevation.

    The present study focuses on the evolution of the Ombrone River delta (Southern Tuscany, Italy) in the last five centuries, when fluvial sediment input was huge also as a consequence of the deforestation performed on the watershed. The aim of this study is to find a correlation between river input and beach ridges morphology and to explain the different distribution of wetlands and sand deposits on the two sides of the delta. Visible, NIR and TIR satellite images were processed to retrieve soil wetness associated to sand ridges and interdune silty deposits. High resolution LiDAR data were analysed using vegetation filter and GIS enhancement algorithms in order to highlight small morphological variations, especially in areas closer to the river where agriculture has almost deleted these morphologies. A topographic survey and a very high resolution 3D model obtained from a set of images acquired by an Unmanned Aerial Vehicle (UAV) were carried out in selected sites, both to calibrate satellite LiDAR 3D data, and to map low relief areas. Historical maps, aerial photography and written documents were analysed for dating ancient shorelines associated to specific beach ridges. Thus allowing the reconstruction of erosive and accretive phases of the delta. Seventy beach ridges were identified on the two wings of the delta. On the longer down-drift side (Northern wing) beach ridges are more spaced at the apex and gradually converge to the extremity, where the Bruna River runs and delimits the sub aerial depositional area of the Ombrone River. On the shorter up-drift lobe (Southern wing), beach ridges are closer, but run almost parallel each other. In this case, a rocky headland called Collelungo promontory closes and cuts the beach ridges sequence but shallow water depth allows sediment by pass. One kilometre to the south a more pronounced promontory encloses a small pocket beach (Cala di Forno) and identifies the limit of the subaerial depositionary area. Beach ridges

    Beach sand is a habitat that supports many microbes, including viruses, bacteria, fungi and protozoa (micropsammon). The apparently inhospitable conditions of beach sand environments belie the thriving communities found there. Physical factors, such as water availability and protection from insolation; biological factors, such as competition, predation, and biofilm formation; and nutrient availability all contribute to the characteristics of the micropsammon. Sand microbial communities include autochthonous species/phylotypes indigenous to the environment. Allochthonous microbes, including fecal indicator bacteria (FIB) and waterborne pathogens, are deposited via waves, runoff, air, or animals. The fate of these microbes ranges from death, to transient persistence and/or replication, to establishment of thriving populations (naturalization) and integration in the autochthonous community. Transport of the micropsammon within the habitat occurs both horizontally across the beach, and vertically from the sand surface and ground water table, as well as at various scales including interstitial flow within sand pores, sediment transport for particle-associated microbes, and the large-scale processes of wave action and terrestrial runoff. The concept of beach sand as a microbial habitat and reservoir of FIB and pathogens has begun to influence our thinking about human health effects associated with sand exposure and recreational water use. A variety of pathogens have been reported from beach sands, and recent epidemiology studies have found some evidence of health risks associated with sand exposure. Persistent or replicating populations of FIB and enteric pathogens have consequences for watershed/beach management strategies and regulatory standards for safe beaches. This review summarizes our understanding of the community structure, ecology, fate, transport, and public health implications of microbes in beach sand. It concludes with recommendations for future work in

  7. Medium-term dynamics of a middle Adriatic barred beach

    2017-09-01

    Full Text Available In recent years, attention has been paid to beach protection by means of soft and hard defenses. Along the Italian coast of the Adriatic Sea, sandy beaches are the most common landscape feature and around 70 % of the Marche region's coast (central Adriatic is protected by defense structures. The longest free-from-obstacle nearshore area in the region includes the beach of Senigallia, frequently monitored in the last decades and characterized by a multiple bar system, which represents a natural beach defense. The bathymetries surveyed in 2006, 2010, 2011, 2012 and 2013 show long-term stability, confirmed by a good adaptation of an analyzed stretch of the beach to the Dean-type equilibrium profile, though a strong short- to medium-term variability of the wave climate has been observed during the monitored periods. The medium-term dynamics of the beach, which deal with the evolution of submerged bars and are of the order of years or seasons, have been related to the wave climate collected, during the analyzed temporal windows, by a wave buoy located about 40 km off Senigallia. An overall interpretation of the hydrodynamics, sediment characteristics and seabed morphology suggests that the wave climate is fundamental for the morphodynamic changes of the beach in the medium term. These medium-term time ranges during which waves mainly come from NNE/ESE are characterized by a larger/smaller steepness and by a larger/smaller relative wave height, and seem to induce seaward/shoreward bar migration as well as bar smoothing/steepening. Moving southeastward, the bar dimension increases, while the equilibrium profile shape suggests the adaptation to a decreasing sediment size in the submerged beach. This is probably due to the presence of both the harbor jetty and river mouth north of the investigated area.

  8. Sediment Transport and erosion modeling at Heaundae Beach in Korea.

    The sand pocket beaches with two headlands are global features, but it's not easy to predict berm and dune erosion due to alongshore variation of water depth. This study investigates the sediment transport and morphological change using available wave and beach profile data, as well as to assess the applicability of the XBeach morphological model (Roelvink et al., 2009). The Haeundae is small pocket beach, 1.4 km long, located in the southern corner of the Korean Peninsula. The Korea Institute of Ocean Science and Technology (KIOST) measured beach profile along 27 survey lines. The beach profiles were surveyed five times from 17 June 2014 to 10 October 2014. For this duration, a wave gauge (AWAC) was installed at a depth about 23 m off the coast of Haeundae Beach. Severe four storms attacked Haeundae Beach for this duration and these storms lasted about 1 2 days with a peak significant wave height of 2.5 4.0 m. The placed sand is fairly sorted and its median diameter is 0.23 mm. 2DH coastal morphological model, XBeach developed to simulate dune erosion due to storm impacts. The model is based on the nonlinear shallow water equation and resolves nearshore hydrodynamics by employing a 2DH description of wave groups and infragravity motions. In this study, the numerical model XBeach was compared with the field data and used to estimate the sediment transport pattern on the sand pocket beach. The numerical model resulted in a comparable prediction in the west-part, but the east-part cannot reproduce the erosion and accretion of the sand, partly due to complex bathymetry and the lack of sediment. This limitation needs to be improved to use measured sand thickness data in future study

    2017-12-01

    To enhance protection and maintain wide beaches for recreation, beaches are replenished with sand: so-called beach nourishments. We compared four sites: two traditional beach nourishments, a mega beach nourishment and a reference without beach nourishment. Two sites contain calcareous-rich sand, whereas the other two sites have calcareous-poor sand. We aimed to understand hydrogeochemical processes to indicate factors critical for the mobility of trace elements at nourishments. We therefore analysed the chemical characteristics of sediment and pore water to ascertain the main drivers that mobilise toxic trace elements. With Dutch Quality Standards for soil and groundwater, the characteristics of sediment and pore water were compared to Target Values (the values at which there is a sustainable soil quality) and Intervention Values (the threshold above which the soil's functions are at risk). The pore water characteristics revealed that Target Values were regularly exceeded, especially for the nourishment sites and mainly for Mo (78%), Ni (24%), Cr (55%), and As (21%); Intervention Values for shallow groundwater were occasionally exceeded for As (2%), Cr (2%) and Zn (2%). The sediment characteristics did not exceed the Target Values and showed that trace elements were mainly present in the fine fraction of trace metal mobility at a mega beach nourishment it is important to retain seawater influences and limit oxidation processes. In this respect, a shoreface nourishment is recommended rather than a mega beach nourishment with a thick unsaturated zone. Consequently, we conclude that whether a site is carbonate-rich or carbonate-poor is unimportant, as the influence of seawater will prevent decalcification, creating a low risk of mobilisation of trace elements.

    2017-10-01

    Beachrock is present in deep, stable sections of a mixed sand and gravel beach at Whitepark Bay (55o14‧N) on the paraglacial coast of Northern Ireland. The beachrock was revealed following progressive and extreme beach erosion during two particularly stormy winters (2013/14 and 2014/15). It occurs as large (up to 1 m diameter, 0.2 m thick), rounded, disc-shaped concretions in which original beach bedding structures are preserved. Both sand and gravel beach facies are cemented. The cements are similar to those of tropical beachrocks and comprise an initial thin micrite rim, and subsequent grain rims of aragonitic needles. The cementation is attributed to saturation of beach groundwater with calcium carbonate sourced from adjacent Cretaceous chalk outcrop in cliffs behind the beach and dunes. The micrite rims suggest microbial activity in the initial cementation, possibly by scavenging from chalk and skeletal carbonate grains. Subsequent aragonite rims were formed through degassing of CO2 aided by tidal water level fluctuations. Despite similar cementation processes to low latitude beachrocks, only isolated concretions occur rather than extensive shore-parallel outcrops. Conditions necessary for cementation (and ultimately preservation) in this cold temperate and paraglacial setting include long-term beach stability, a carbonate source (in this case, adjacent chalk cliffs and stream sapping) and tidal water level fluctuations. Bacterial activity may initiate calcite precipitation. Following extreme storms and with progressive shoreline retreat prompted by rising sea levels, increased reporting of cold-water beachrocks is to be expected as formerly stable sections of beaches are exposed to wave action.

    In this work the concentrations of natural radionuclides 226 Ra, 232 Th and 40 K were determined in superficial sand samples for 16 locations throughout the coast of the Great Victory, metropolitan region of the state of Espirito Santo, Southeast of Brazil. The assessed beaches were Manguinhos and Jacaraipe in Serra county, Camburi, Praia do Canto and Curva da Jurema in Vitoria county, Praia da Costa and Itapua in Vila Velha county, Setibao, Setibinha, Praia do Morro, Praia das Castanheiras and Areia Preta in Guarapari county and sand of the Paulo Cesar Vinha Reserve also located in Guarapari county. Three sand samples of each beach were sealed in 100 mL high density polyethylene flasks. After approximately 4 weeks in order to reach secular equilibrium in the 238 U and 2 '3 2 Th series, the samples were measured by high resolution gamma spectrometry and the spectra analyzed with the WinnerGamma software. The self absorption correction was performed for all samples. The 226 Ra concentration was determined from the weighted average concentrations of 214 Pb and 21 '4Bi, the 232 Th concentration was determined from the weighted average concentrations of 228 Ac, 2 '1 2 Pb and 212 Bi and the concentration of 40 K is determined by its single gamma transition of 1460 keV. The radium equivalent concentration and the external hazard index where obtained from the concentrations of 226 Ra, 232 Th and 4 '0K. 226 Ra concentrations show values varying from 3 +- 1 Bq.kg-1 to 738 +- 38 Bq.kg -1 , with the highest values for the central locality of the Camburi beach. 232 Th concentrations show values varying from 7 +- 3 Bq.kg -1 to 7422 +- 526 Bq.kg -1 , with the highest values for Areia Preta beach. 40 K concentrations show values varying from 14 +- 6 Bq.kg -1 to 638 +- 232 Bq.kg -1 , with the highest values for Areia Preta beach.

    The sea, as well as being a destructive force can also be constructive and can move great quantities of sand often forming a beach. Waves can move material both up and down the beach, leading to the construction of sloping beaches. Wave-sand dynamics are studied via experiments. The tank is narrow, just over one-particle diameter wide, creating a quasi-2D set-up also geared towards mathematical modelling. There is strong two-way feedback between the free-surface waves and the beach morphology. The waves transport the particles, changing the basal topography, causing the waves to transform from rolling to breaking. ``All'' classical breaker types (plunging, collapsing, spilling and surging) are observed on a time-scale of about a second. Finally, on longer time-scales many steady beach morphologies are observed, including dry and wet beaches, dry berms/dunes, and bars. The highlight being dry dunes which have dynamic waves crashing on the seaward-side and quiescent water on the far side.

    Costing studies are needed to identify the resources used for treatment and inform payers of the costs incurred. The objectives were to determine the costs of diagnosing and treating atopic dermatitis, food allergy and asthma, and to compare the share of costs to society and to the family during the first two years of life. The data were obtained from an ongoing mother-infant nutrition study. The sample comprised 60 infants who developed allergic disease by the age of 24 months and 56 healthy infants with no allergic disease. The costs included diagnosis and treatment of the allergy, disability allowances, travel expenses and time spent by parents. The median costs per infant were €275 (range 94-1306) for atopic dermatitis, €1408 (163-5408) for asthma, €3182 (628-11195) for food allergy, and €10 (0-619) for the healthy infants due to the suspicion of allergic disease. The highest costs in atopic dermatitis were caused by primary care visits, topical treatments, travel costs and parents' time, and those for food allergy by hospital out-patient care, infant formulae for cow's milk allergy, disability allowances and travel costs. The families paid 43% of the costs arising from atopic dermatitis, 13.6% of those from food allergy and 16.5% of those from asthma. Cow's milk allergy emerged as the most expensive allergic disease, especially for the society, and concurrent asthma in particular further increased the costs.

    To assess patient characteristics associated with adverse outcomes in the first 2 years following tracheostomy, and to report healthcare utilization and cost of caring for these children. Retrospective cohort study. Children (0-16 years) in Medicaid from 10 states undergoing tracheostomy in 2009, identified with International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes and followed through 2011, were selected using the Truven Health Medicaid Marketscan Database (Truven Health Analytics, Inc., Ann Arbor, MI). Patient demographic and clinical characteristics were assessed with likelihood of death and tracheostomy complication using chi-square tests and logistic regression. Healthcare use and spending across the care continuum (hospital, outpatient, community, and home) were reported. A total of 502 children underwent tracheostomy in 2009, with 34.1% eligible for Medicaid because of disability. Median age at tracheostomy was 8 years (interquartile range 1-16 years), and 62.7% had a complex chronic condition. Two-year rates of in-hospital mortality and tracheostomy complication were 8.9% and 38.8%, respectively. In multivariable analysis, the highest likelihood of mortality occurred in children age tracheostomy complication was in children with a complex chronic condition versus those without a complex chronic condition (OR 3.3; 95% CI, 1.1-9.9). Total healthcare spending in the 2 years following tracheostomy was $53.3 million, with hospital, home, and primary care constituting 64.4%, 9.4%, and 0.5% of total spending, respectively. Mortality and morbidity are high, and spending on primary and home care is small following tracheostomy in children with Medicaid. Future studies should assess whether improved outpatient and community care might improve their health outcomes. 4.

    Full Text Available Purpose : To evaluate the clinical characteristics of vitamin D deficiency and its association with iron deficiency anemia (IDA. Methods : A total of 171 children aged less than two years underwent 25-hydroxyvitamin D3 tests between January 2007 and July 2009. The study was classified into two groups: normal and vitamin D insufficiency, by their vitamin 25-hydroxyvitamin D3 levels. Results : In total, 120 children were in the normal group (mean age, body weight and heights 12.5±7.0, 9.3±0.9 kg and 76.8±1.1 cm, and 51 children in the vitamin D insufficiency group (9.9±5.4 months, 9.0±0.9 kg and 75.1±0.9 cm. Vitamin D insufficiency was most commonly diagnosed in the spring (44%. The proportion of complete breast-feeding was higher in the insufficiency (92%, and 25.5% of the children in the deficient group also experienced IDA compared that 12% of normal group. Ten children in the insufficiency group experienced bony changes. Six children received calcitriol medication in the normal group, in whom the mean vitamin 25-hydroxyvitamin D3 level increased from 39.6±14.6 ng/mL (pre-medication to 41.8±17.2 ng/mL (post-medication, and 13 in the insufficiency group, in whom the mean vitamin 25-hydroxyvitamin D3 increased from 20.7±7.0 ng/ mL to a mean post-treatment level of 43.7±23.8 ng/mL. Conclusion : This study demonstrated that approximately 30% of children aged ?#178; years experienced vitamin D insufficiency associated with subclinical rickets. Many children also experienced concurrent IDA. Guidelines for vitamin D supplement in such children must therefore be established.

    The recent PCAST report (2012), Engage to Excel, calls for a major shift in instructional modes in introductory (geo)science courses by "replacing standard laboratory courses with discovery-based research courses". An increased emphasis is recommended to engage students in experiments with the possibility of true discovery and expanded use of scientific research courses in the first two years. To address this challenge, the On the Cutting Edge program convened a workshop of geoscience faculty to explore the many ways that true research experiences can be built into introductory geoscience courses. The workshop goals included: consideration of the opportunities, strategies and methods used to provide research experiences for students in lower division geoscience courses; examination of ways to develop students' "geoscience habits of mind" through participation in authentic research activities; exploration of ways that student research projects can be designed to contribute to public science literacy with applications to a range of issues facing humanity; and development of strategies to obtain funding for these research projects, to make these programs sustainable in departments and institutions, and to scale-up these programs so that all students may participate. Access to Earth data, information technology, lab and field-based instrumentation, and field experiences provide unprecedented opportunities for students to engage in authentic research at early stages in their careers. Early exposure to research experiences has proven to be effective in the recruitment of students to the geoscience disciplines, improved retention and persistence in degree programs, motivation for students to learn and increase self-efficacy, improved attitudes and values about science, and overall increased student success. Workshop outcomes include an online collection of tested research projects currently being used in geoscience classes, resources related to effective design

    Careers in energy science related fields represent significant job growth in the U.S. Yet post-secondary career and technical programs have not kept pace with demand and energy science curriculum, including fundamental concepts of energy generation and environmental impact, lacks a firm position among general or career and technical education courses. Many of these emerging energy related jobs are skilled labor and entry level technical positions requiring less than a bachelor's degree. These include jobs such as solar/photovoltaic design and installation, solar water and space heating installation, energy management, efficiency and conservation auditor, environmental technician, etc. These energy related career pathways fit naturally within the geosciences discipline. Many of these jobs can be filled by individuals from HVAC, Industrial technology, welding, and electrical degree programs needing some additional specialized training and curriculum focused on fundamental concepts of energy, fossil fuel exploration and use, atmospheric pollution, energy generation, alternative energy sources, and energy conservation. Two-year colleges (2ycs) are uniquely positioned to train and fill these workforce needs as they already have existing career and technical programs and attract both recent high school graduates, as well as non-traditional students including displaced workers and returning veterans. We have established geoscience related workforce certificate programs that individuals completing the traditional industrial career and technical degrees can obtain to meet these emerging workforce needs. This presentation will discuss the role of geosciences programs at 2ycs in training these new workers, developing curriculum, and building a career/technical program that is on the forefront of this evolving industry.

    Vanilla planifolia embryogenic calli were cultured for two years on a medium containing thidiazuron (TDZ). Due to the presence of TDZ, these calli were under permanent chemical treatment and the differentiation of adventitious shoots from protocorm-like-bodies (PLBs) was blocked. When embryogenic calli were transferred onto a medium without TDZ, shoot organogenesis and plantlet regeneration occurred. To gain better knowledge about the biochemical and molecular processes involved in the morphoregulatory role of TDZ, hormonal and metabolomic analyses were performed. Our results indicate that in the presence of TDZ, embryogenic calli contained a high amount of abscisic acid (ABA) essentially metabolized into abscisic acid glucosyl ester (ABAGE) and phaseic acid (PA), which was the most abundant. When transferred onto a medium without TDZ, shoot regeneration and development take place in four stages that include: embryogenic calli growth, differentiation of PLBs from meristmatic cells zones (MCZ), shoot organogenesis from PLBs and the elongation of well-formed shoots. From a hormonal perspective, the significant reduction in ABA metabolism and its readjustment in the ABAGE pathway triggered PLBs formation. However, this first morphogenesis was stimulated by a strong reduction in IAA metabolism. The organogenesis of PLBs into shoots is associated with an increase in ABA catabolism and a gradual shift in cellular metabolism towards shoot differentiation. Thus, the initiation of the elongation process in shoots is correlated with an alteration in metabolite composition, including an increase in energy reserves (sucrose/starch) and a rapid decrease in alanine content. Our data highlighted the relationship between endogenous hormone signalling, carbohydrate metabolism and shoot organogenesis in Orchid plants. Copyright © 2015 Elsevier Masson SAS.

    To generate evidence on the longer term cost effectiveness of disease modifying treatments in patients with relapsing-remitting multiple sclerosis. Prospective cohort study with historical comparator. Specialist multiple sclerosis clinics in 70 centres in the United Kingdom. Patients with relapsing-remitting multiple sclerosis who started treatment from May 2002 to April 2005 under the UK risk sharing scheme. Treatment with interferon beta or glatiramer acetate in accordance with guidelines of the UK Association of British Neurologists. Observed utility weighted progression in disability at two years' follow-up assessed on the expanded disability status scale (EDSS) compared with that expected by applying the progression rates in a comparator dataset, modified for patients receiving treatment by multiplying by the hazard ratio derived separately for each disease modifying treatment from the randomised trials. In the primary per protocol analysis, progression in disability was worse than that predicted and worse than that in the untreated comparator dataset ("deviation score" of 113%; excess in mean disability status scale 0.28). In sensitivity analyses, however, the deviation score varied from -72% (using raw baseline disability status scale scores, rather than applying a "no improvement" algorithm) to 156% (imputing missing data for year two from progression rates for year one). It is too early to reach any conclusion about the cost effectiveness of disease modifying treatments from this first interim analysis. Important methodological issues, including the need for additional comparator datasets, the potential bias from missing data, and the impact of the "no improvement" rule, will need to be addressed and long term follow-up of all patients is essential to secure meaningful results. Future analyses of the cohort are likely to be more informative, not least because they will be less sensitive to short term fluctuations in disability.

    Abstract Aims The relationship between outcomes and time after diagnosis for patients with non-valvular atrial fibrillation (NVAF) is poorly defined, especially beyond the first year. Methods and results GARFIELD-AF is an ongoing, global observational study of adults with newly diagnosed NVAF. Two-year outcomes of 17 162 patients prospectively enrolled in GARFIELD-AF were analysed in light of baseline characteristics, risk profiles for stroke/systemic embolism (SE), and antithrombotic therapy. The mean (standard deviation) age was 69.8 (11.4) years, 43.8% were women, and the mean CHA2DS2-VASc score was 3.3 (1.6); 60.8% of patients were prescribed anticoagulant therapy with/without antiplatelet (AP) therapy, 27.4% AP monotherapy, and 11.8% no antithrombotic therapy. At 2-year follow-up, all-cause mortality, stroke/SE, and major bleeding had occurred at a rate (95% confidence interval) of 3.83 (3.62; 4.05), 1.25 (1.13; 1.38), and 0.70 (0.62; 0.81) per 100 person-years, respectively. Rates for all three major events were highest during the first 4 months. Congestive heart failure, acute coronary syndromes, sudden/unwitnessed death, malignancy, respiratory failure, and infection/sepsis accounted for 65% of all known causes of death and strokes for <10%. Anticoagulant treatment was associated with a 35% lower risk of death. Conclusion The most frequent of the three major outcome measures was death, whose most common causes are not known to be significantly influenced by anticoagulation. This suggests that a more comprehensive approach to the management of NVAF may be needed to improve outcome. This could include, in addition to anticoagulation, interventions targeting modifiable, cause-specific risk factors for death. Clinical Trial Registration http://www.clinicaltrials.gov.

    This paper assessed the associations between sports participation and the development of psychological strengths and difficulties during childhood. Two-year follow up study of a sample of 4042 Australian children who were followed from age 8 years to 10 years. Parents reported children's participation in organised sports, and completed the Strengths and Difficulties Questionnaire. Univariate general linear models were used to examine the association between changes in sports participation and psychological strengths and difficulties at 10 years, adjusting for psychological strengths and difficulties at age 8. Children who maintained participation in sport had lower rates of parent-reported psychological difficulties at 10 years compared with children who dropped out of sport. Less internalising problems were also reported for children who participated in organised sports compared to children who dropped out of sports and children who did not participate in sports. These relationships did not differ by BMI, socioeconomic status, or parental education. Greater psychological difficulties are experienced by children who drop out of sports, and greater social and emotional problems are experienced by children who drop out of sports and who do not participate in organised sports. Due consideration should be given to the quality and implementation of sporting programs to ensure that they provide benefits to mental health. Due consideration should also be given to the potential psychological difficulties being experienced by children who drop out of organised sports as a higher level of psychological difficulties may be experienced prior to or subsequent to dropout.

    Patients with Crohn's disease have an increased frequency of osteopenia and osteoporosis. This randomized, controlled, double-blind study assessed the efficacy of risedronate versus placebo in treating low bone mineral density (BMD) in patients with Crohn's disease. 88 Crohn's disease outpatients with BMD T-score<-1.0 by dual-energy X-ray absorptiometry were randomly assigned to one of two treatment groups for the two year study duration: one group received risedronate 35 mg weekly while another received placebo. Both groups received daily calcium (Ca; 500 mg) and vitamin D (D; 400 IU) supplementation. Percent change in BMD relative to baseline was compared between the two therapies at 12 and 24 months. Using intent-to-treat analysis, at 12 months, risedronate+Ca+D increased BMD, relative to baseline, more than placebo+Ca+D in the femoral trochanter (1.4±3.4% vs -0.1±3.1%; p=0.03) and total hip (1.1±2.7% vs -0.1±2.5%;p=0.04). This trend in greater BMD continued for the 24 month duration of the study. There was no difference between the two treatment groups for changes in spine BMD. Subgroup analysis revealed that risedronate+Ca+D resulted in significantly better improvement in femoral trochanter BMD in non-smokers (p=0.01), males (p=0.01), those with a history of corticosteroid use in the preceding year (p=0.01), and current users of immunosuppressants (p=0.04). Risedronate, in addition to daily calcium and vitamin D supplementation, is superior to calcium and vitamin D alone in improving femoral trochanter and total hip BMD in patients with Crohn's disease.

    Full Text Available A 50-year-old female was admitted to our department, complaining of progressive numbness of distal limbs for two years and unsteady gait for two months. “Peripheral neuropathy” was the presumed diagnosis. She has suffered dry mouth for months. Neurological examination revealed proximal upper muscle strength was normal and distal was 5-/5 while muscle strength in lower limbs was normal. Tendon reflexes in all limbs were reduced, and superficial sensation as well as deep sensation in all limbs was also diminished. Deep sensation below T8-10 was diminished. Romberg’s test was positive with negative pathological reflex. Several sensory nerves action potentials (SNAPs were diminished or absent with normal compound muscle action potentials (CMAPs. Cervical MRI showed hyperintensities in the dorsal column. Serum anti-Ro/SSA antibody was positive. Tear break-up time was abnormal in either eye (5s, normal range>10s; the rate of saliva production declined 0.02 ml/min (> 1.50 ml/15 min; parotid gland contrast sialography was abnormal; lip biopsy was positive with focal lymphocytic sialadenitis with focus score ≥1. The patient was diagnosed as primary Sjogren's syndrome and sensory neuronopathy. She received oral prednisone in dose of 1mg/(kg·d for four weeks, then reduce the dosage with 5mg/w to 0.50mg/ (kg·d. Later she reduced the dosage with 2.5mg/per week. At the same time, she got cyclophosphamide (100mg every other day and hydroxychloroquine (0.20g twice a day. Numbness of limbs and unsteady gait were improved when the patient was discharged. Two month later, during the follow-up, the patient’ gait was slightly improved, but the numbness still existed. DOI: 10.3969/j.issn.1672-6731.2016.11.016

    The Mercury Laser Altimeter (MLA) on the MESSENGER spacecraft has been ranging to the planet Mercury since March 2011, first in a 12-h, 83.5°-inclination orbit, and currently in an 8-h orbit. The orbital periapsis latitude, initially at 60°N, moved slowly northward during the first two years of the orbital mission, enabling near-complete coverage of the northern hemisphere with ~15 million measured radii. Targeted observations during the first extended mission allowed mapping of nearly all regions of extensive shadow within northern high-latitude craters. The refined topography provides a comprehensive dataset for geological studies, illumination and thermal modeling, and studies of the interior. The strength of laser returns in relation to the 10-20 mJ energy of the outgoing laser pulses has provided ~8.7 million active measurements of surface reflectance. Initial results, in conjunction with neutron spectrometry and Earth-based radar, confirmed the existence of water ice exposed at the surface within the deepest shadows of Prokofiev Crater at 85° N and other regions of high radar cross-section, as well as darker volatile species that provide an insulating surficial layer for most radar-bright polar deposits. Refined measurements of reflectance, corroborated by imaging of shadowed regions illuminated by scattered light, reveal the areal extent of polar deposits. These deposits expose water ice at the surface only in limited regions where surface temperatures are predicted never to exceed the long-term stability limit of water ice, whereas subsurface temperatures in other areas of permanent shadow predict the long-term preservation of more extensive deposits of water ice and other volatiles if that material is overlain by an insulating layer.

  12. The good, the bad, and the ugly, of the two year review cycle

    With the adoption of the 1996 Edition of the ''Regulations for the Safe Transport of Radioactive Material'' IAEA began a biennial process for the review and potential modifications of the regulations. IAEA members are currently in the third review cycle; this experience provides a perspective of the benefits, the problems and the discord with this process. This paper presents a perspective of the nuclear industry on these issues. It also includes recommendations to make the process more meaningful and of greater value to all parties that involved. ''The Good'' will focus on the benefits, ''The Bad'' will identify the problems, and ''The Ugly'' will cover the discords. ''The Good'' An effective safety program/procedure includes a provision for periodic review and, if warranted, modifications. The 1996 Edition provides a schedule and a plan for executing that schedule. This provides for a logical review and modification and therefore a plan for keeping the regulations current. ''The Bad'' The benefit of a review of the regulations is lost when it is consumed by minor editorial changes that have minimal positive impact on safety. The use of limited resources to address insignificant changes results in a reduction of resources for safety in other aspects of the transportation area. The two year review should capture these minor changes but the implementation should be deferred until prompted by a significant change requirement or the volume of minor changes warrants a revision of the regulations. ''The Ugly'' The ugly part of the process is the adoption of the changes by the various competent authorities. In some competent authorizes it is a simple dictate that this is the way it will be, while other authorities have a very open public process with public participation and open meetings. The result is there is not uniform adoption of the changes either in timing or in consistency

    Implanon is a new long-term and reversible sub-dermal contraceptive implant in Nigeria. It is a single rod containing 68mg of etonogestrel meant to offer contraception for three years and marketed by Organon. To determine the indications for removal of Implanon rods from clients within a two-year period. A retrospective review of 30 consecutive Implanon removals within the study period. The fertility regulation unit of the department of obstetrics and gynaecology of the Jos University Teaching Hospital, North-Central Nigeria. A total of 30 clients requested for and had their Implanon rods removed out of 669 insertions constituting 95.5% crude continuation rate in the second year. The clients were of mean age 31.4 +/- 6.2 years, mean parity 2.9 +/- 1.8 and mean number of living children 2.7 +/- 1.6. There was an average weight gain of 1.9 kg. The most common indication for removal was menstrual disruption (33.3%). Desire for another pregnancy closely followed (30.0%). Weight gain was another indication for discontinuation (13.3%). Two women were pregnant at insertion of the implant. There was one failure of the method with pregnancy as a result. Spousal disapproval was an indication for removal in two cases. Like all progestin-only contraceptive methods, menstrual disruption was the most common indication for removal of implants. Inadvertent insertion of implants with existing pregnancy is of concern and should be avoided as much as is possible. In doubtful cases at insertion, this insertion should be deferred or serum beta-HCG should be assessed to exclude chemical pregnancy.

    The aim of this study was to determine the clinical durability of two locally manufactured amalgams. In each of eighty-two patients one class II cavity was restored with Dispersalloy (Johnson and Johnson) which served as the control and all the other class II cavities were randomly restored with one of the following amalgams: Amalgaphase, Amalga 43 (Amalgam Alloys-South Africa) or Permite C (Southern Dental Industries). Matrix bands were placed. Kalzinol bases and Polyvar varnish were applied in all cavities. All amalgams were mixed according to the manufacturers' instructions. The cavities were overpacked with amalgam, and the amalgam condensed by hand, carved and then burnished with a ball burnisher. Twenty-four hours later all restorations were polished with a Shofu polishing system and colour photographs were taken. The restorations were evaluated using the Ryge and Snyder (1973) evaluation system, as well as comparison of the colour photos. The Fisher's Exact Test was used for the statistical analysis. During the second year there were no significant (p amalgam restorations except as regards the gloss category. The two South African manufactured amalgams compared well with the two imported amalgams. During the second year the marginal integrity and surface texture of Amalgaphase compared well with that of Permite C. Dispersalloy and Permite C showed more deterioration in anatomic form than the two South African amalgams. Amalgaphase was the only amalgam to show no bulk fracture within a period of two years. Amalgaphase performed better in the gloss category than the other three amalgams during the second year evaluation. According to the weighted product calculation Amalgaphase was the best amalgam followed by Dispersalloy, Amalga 43 and Permite C.

    Late-life depression often has a chronic course, with debilitating effects on functioning and quality of life; there is still no consensus on important risk factors explaining this chronicity. Cross-sectional studies have shown that childhood abuse is associated with late-life depression, and in longitudinal studies with chronicity of depression in younger adults. We aim to investigate the impact of childhood abuse on the course of late-life depression. Two-year longitudinal cohort study. Data were derived from the Netherlands Study of Depression in Older Persons (NESDO). 282 participants with a depression diagnosis in the previous 6 months (mean age: 70.6 years), of whom 152 (53.9%) experienced childhood abuse. Presence of childhood abuse (yes/no) and a frequency-based childhood abuse index (CAI) were calculated. Dependent variable was depression diagnosis after 2 years. Multivariable mediation analysis showed an association between childhood abuse and depression diagnosis at follow-up. Depression severity, age at onset, neuroticism, and number of chronic diseases were important mediating variables of this association, which then lost statistical significance. For childhood abuse (yes/no), loneliness was an additional, significant mediator. Depression severity was the main mediating variable, reducing the direct effect by 26.5% to 33.3% depending on the definition of abuse (respectively, 'yes/no" abuse and CAI). More depressive symptoms at baseline, lower age at depression onset, higher levels of neuroticism and loneliness, and more chronic diseases explain a poor course of depression in older adults who reported childhood abuse. When treating late-life depression it is important to detect childhood abuse and consider these mediating variables. Copyright © 2017 American Association for Geriatric Psychiatry.

    To evaluate the influence of family habits and household characteristics on the consumption of sugary drinks by Brazilian children under two years old. This was a cross-sectional study that used secondary data generated by the National Health Survey (PNS) in 2013. We studied 4,839 pairs of children under two years old and adults living in the same house. We estimated the prevalence of the indicator of sugary drinks consumption for the total sample of children and according to family and household variables. We applied multiple logistic regression analysis to evaluate the influence of family habits and household characteristics on the consumption of sugary drinks by the children. The consumption of sugary drinks was identified in 32% of the studied children (95%CI 30.6-33.3) and was independently associated with the following family and household characteristics: regular consumption of sugary drinks by the adult living in the house (OR = 1.78; 95%CI 1.51-2.10), watching TV for more than three hours per day (OR = 1.22; 95%CI 1.03-1.45), older age (OR = 3.10; 95%CI 1.54-6.26), greater education level (OR = 0.70; 95%CI 0.53-0.91), house located in the Northeast region (OR = 0.65; 95%CI 1.54-6.26), and number of family members (OR = 1.05; 95%CI 1.00-1.09). Our findings indicate the high prevalence of sugary drinks consumption by Brazilian children under two years old and show that sociodemographic characteristics and family habits affect this feeding practice not recommended in childhood.

    For over a decade, the U.S. Geological Survey (USGS) has been a leader in the science of beach health. The overall mission of this work is to provide science-based information and methods that will allow beach managers to more accurately make beach closure and advisory decisions, understand the sources and physical processes affecting beach contaminants, and understand how science-based information can be used to mitigate and restore beaches and protect the public. The work consists of four science elements-real-time assessments; pathogens and microbial source tracking; coastal processes; and data analysis, interpretation, and communication - which are described in this fact sheet. Some of the key questions for USGS beach research are the following: Are there better ways to inform the public whether they can use a beach without risking their health? How do new rapid analytical methods compare to traditional methods for determining concentrations of fecal-indicator bacteria at beaches? Are pathogens present at beaches and, if so, how do they get to the beach, and what is their source? How do sand movement and wave action on the beach affect fecal-indicator-bacteria and pathogen concentrations in the lake water? What are the best indicators of pathogenic microorganisms? With so many potential sources of fecal contamination at a beach, what methods can be used to distinguish the contributions from humans? What characteristics of beaches contribute most to influencing bacterial indicator and pathogen concentrations in beach sands and groundwater?

    Several studies on barred beaches in settings with mesotidal to macrotidal regimes have focused on cross-shore and alongshore bar mobility. Whereas the general link between hydrodynamics, sediment transport and the response of the intertidal bars and shoreline evolution has been recognized in the literature, the role of coastal defense structures (Breakwaters, groins, seawalls) on bar-trough systems morphodynamics have received more much less attention and the field-based experimental studies of these environments are rare. The main aim of this paper is to highlight the contrasting behavior of a natural and protected barred beach under several hydrodynamics conditions. This paper presents detailed hydrodynamic and morphological data from a field experiment spanning 10 days undertaken in Matalascañas beach, a mesotidal protected vs natural barred beach in the Southern Spanish coast. This mesotidal beach experienced intense erosion in the recent past and therefore it has been partially protected by groins (protection of sea-front touristic residences). During the fieldwork, an intertidal bars in the protected and non-protected areas highlighted contrasting morphological behaviour. The non-protected barred beach shows a less pronounced bar-trough system than the protected zone. Under low energy conditions (significant wave height 1m), the protected and non-protected zones show a flattening bars processes. The findings of the present study suggest that cross-shore vs longshore bar mobility may even be mitigated by the presence of the groins, which favour onshore than longshore bar migration.

    Sediment samples were collected from two Hawai'ian beaches, Kahuku Beach on O'ahu and Kamilo Beach on the Big Island of Hawai'i. A total of 48,988 large microplastic and small mesoplastic (0.5-8mm) particles were handpicked from the samples and sorted into four size classes (0.5-1mm, 1-2mm, 2-4mm, 4-8mm) and nine color categories. For all sizes combined the most common plastic fragment color was white/transparent (71.8%) followed by blue (8.5%), green (7.5%), black/grey (7.3%), red/pink (2.6%), yellow (1.2%), orange (0.6%), brown (0.3%) and purple (0.2%). Color frequency distribution based on both numbers and mass of particles was not significantly different among the various size classes nor between the two beaches. White and black/grey resin pellets accounted for 11.3% of the particles collected from Kahuku Beach and 4.2% of the particles from Kamilo Beach. Plastic type based on Raman Spectrometer analysis of a small representative subsample indicated that most of the fragments were polyethylene and a few were polypropylene.

    India has got a wealth of natural resources in different geological environs and shoreline placers form an important constituent of the natural resources. Large reserves of beach sand minerals, viz. imenite, rutile, leucoxene, zircon, sillimanite, garnet and monazite are the economic minerals in the coastal and inland placer sands. In the federal structure of India, the State Governments are the owners of minerals located within their respective boundaries. The State Governments grant the mineral concessions for all the minerals located within the boundary of the State, under the provisions of the Acts and Rules framed for the purpose. Though the mineral wealth is under the control of the State, the power for framing the rules for the grant of mineral concessions vastly rest with the Central Government. Since mineral concessions are often granted for a longer duration of thirty to fifty years or more, a historical perspective of these rules are imperative in understanding the issues involved with BSM mining industry. Under the Govt. of India Act, 1935, Regulation of Mines and Oilfields and Mineral Development was kept under Federal control, declared by Federal Law. The word 'Federal' was substituted by the word 'Dominion' by the India (Provincial Constitution) Order, 1947. No legislation was, however, enacted in pursuance of above power until after Independence. However, the Govt. on India made the Mining Concession (Central) Rules, 1939 for regulating grants of prospecting license

    Mine tailings dams are embankments used by the mining industry to retain the tailings products after the mineral preparation process. Based on the acid-waste stereotype that all coal slurry is acid producing, current reclamation requires a four foot soil cover for inactive slurry disposal areas. Compliance with this requirement is both difficult and costly and in some case unnecessary, as not all the slurry, or portions of slurry impoundments are acid producing. Reduced costs and recent popularity of wetland development has prompted many operators to request reclamation variances for slurry impoundments. Waiting to address slurry reclamation until after the impoundment is full, limits the flexibility of reclamation opportunities. This paper outlines a general methodology to predict the formation of the beach profile for mine tailings dams, by the discharge volume and location of the slurry into the impoundment. The review is presented under the perspective of geotechnical engineering and waste disposal management emphasizing the importance of pre-planning slurry disposal land reclamation. 4 refs., 5 figs.

    The importance of 2-yr postradiotherapy prostate biopsy status remains uncertain. To assess the value of 2 year post treatment biopsies in a randomised trial of radiotherapy dose escalation. Between 1998 and 2001, 843 men with localised prostate cancer were randomised to receive either control-64Gy or escalated-74Gy conformal radiotherapy (CFRT) in the MRC RT01 trial in combination with 3-6-mo neoadjuvant androgen deprivation therapy. Prostate biopsies were planned at 2 yr from start of CFRT in suitable men. Prostate biopsy results and prostate-specific antigen (PSA) levels performed at 2 yr post-CFRT were evaluated with long-term biochemical progression free survival (bPFS) and overall survival. Outcome measures were timed from the 2-yr biopsy using a landmark approach. A 2-yr biopsy was performed in 312/843 patients. One hundred and seventy-seven patients were included in the per-protocol group with median follow-up of 7.8 yr from biopsy. Median PSA at biopsy was 0.5ng/ml. Sixty-four bPFS events were reported: 46/145 (32%) in patients with negative, 6/18 (33%) suspicious, and 12/14 (86%) positive biopsies. A positive biopsy was prognostic of worse bPFS, going forward, compared with negative and suspicious biopsies, hazard ratio (HR)=4.81 (95% confidence interval [CI]: 2.50-9.26, p<0.001). The estimate for survival was HR=1.58 (95% CI: 0.52-4.78, p=0.42). PSA values at 2 yr between 1.01ng/ml and 2.09ng/ml were also associated with subsequent PSA failures (HR=2.71, 95% CI: 1.98-3.71), bPFS events (HR=2.45, 95% CI: 1.81-3.32), and prostate cancer-specific survival (HR=2.87, 95% CI: 1.08-7.64) compared with PSA ≤1.0ng/ml. Two-year postradiotherapy prostate biopsies have limited value in patients with PSA control but both positive biopsy and higher PSA status are strongly associated with future bPFS events. A policy of selected biopsy may provide an opportunity for early salvage interventions. Routine 2-yr postradiotherapy biopsy is not recommended but can be

    The aim of this prospective randomized controlled clinical trial was to evaluate the 2-year clinical performance of a self-adhesive resin cement, RelyX Unicem (3M ESPE), used for cementation of ceramic inlays. In addition, the influence of selectively acid etching enamel prior to luting on marginal integrity, inlay integrity, tooth integrity, sensitivity, and complications of the restored teeth was assessed. The hypothesis tested was that there was no significant difference in these criteria between restorations with (Etch) or without prior enamel acid etching (Non-etch). Sixty-two IPS Empress 2 inlays/onlays were placed in 31 patients by two experienced clinicians. The restorations were luted with RelyX Unicem with (=experimental group; Etch) or without (=control group; Non-etch) prior enamel etching with phosphoric acid. At baseline, 6 months, 1 year and 2 years after placement, the restorations were assessed by two calibrated investigators using modified USPHS criteria. The recall rate at 24 months was 96.6%. Two restorations were clinically unacceptable due to loss of retention, leading to a survival rate of 96.6% (Kaplan-Meier). No significant difference was noted between the experimental group and the control group regarding marginal integrity, inlay integrity, tooth integrity, complications and sensitivity (McNemar, p > 0.05). An obvious deterioration in marginal adaptation was observed after 24 months as only 21.7% (Etch = 23.4%; Non-etch = 20%) of the restorations exhibited an excellent marginal adaptation compared to 70.7% (Etch = 75%; Non-etch = 66.7%) at baseline. In 74.9% of the restorations, small, still clinically acceptable marginal deficiencies were observed (Etch = 76.6%; Non-etch = 73.2%). The self-adhesive resin cement RelyX Unicem showed acceptable clinical behavior after two years of clinical service. Selective enamel etching prior to luting had no significant influence on marginal integrity, inlay integrity, tooth integrity, sensitivity or

    ABSTRACT Purpose Calorie restriction (CR) improves health span and delays age-related diseases in many species. The multicenter Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) study was the first randomized controlled trial of CR in nonobese humans. The aim of this investigation was to determine the effects of CR on V˙O2max and muscle strength in the CALERIE trial. Methods Healthy, normal-weight, and mildly overweight women and men (n = 218, mean ± SE age = 37.9 ± 0.5 yr) were randomized to 25% CR or an ad libitum (AL) control condition in a 2:1 allocation (143 CR, 75 AL). V˙O2max was determined with an incremental treadmill test; the strength of the knee flexors and extensors was assessed by dynamometry at baseline, 1 yr, and 2 yr. Results The CR group achieved an average 11.9% ± 0.7% CR during the 2-yr intervention. Body weight decreased in CR (−7.7 ± 0.4 kg), but not AL (+0.2 ± 0.5 kg). Absolute V˙O2max (L·min−1) decreased at 1 and 2 yr with CR, whereas V˙O2max expressed relative to body mass increased at both time points (1 yr: +2.2 ± 0.4; 2 yr: +1.9 ± 0.5 mL·kg−1·min−1) and relative to AL. The CR group increased their treadmill test time and workload at 1 and 2 yr. Strength results in CR were similar, with decreases in absolute flexor and extensor strength, but increases when expressed relative to body mass. No changes were observed for V˙O2max expressed relative to lean body mass or leg lean mass. Conclusions Two years of modest CR without a structured exercise component did not appear to compromise aerobic capacity in healthy nonobese adults. The clinical implications of the observed changes in V˙O2max and muscle strength will be important to explore in future studies. PMID:29045325

    Backus, Bridgid A.

    Two-year chemistry-based technology training (CBTT) programs in the U.S. are important in the preparation of the professional technical workforce. The purpose of this study was to identify, examine, and analyze factors related to the economic sustainability of CBTT programs. A review of literature identified four clustered categories of 31 sub-factors related to program sustainability. Three research questions relating to program sustainability were: (1) What is the relative importance of the identified factors?, (2) What differences exist between the opinions of administrators and faculty?, and (3) What are the interrelationships among the factors? In order to answer these questions, survey data gathered from CBTT programs throughout the United States were analyzed statistically. Conclusions included the following: (1) Rank order of the importance to sustainability of the clustered categories was: (1) Partnerships, (2) Employer and Student Educational Goals, (3) Faculty and Their Resources, and (4) Community Perceptions and Marketing Strategies. (2) Significant correlations between ratings of sustainability and the sub-factors included: degree of partnering, college responsiveness, administration involvement in partnerships, experiential learning opportunities, employer input in curriculum development, use of skill standards, number of program graduates, student job placement, professional development opportunities, administrator support, presence of a champion, flexible scheduling, program visibility, perception of chemical technicians, marketing plans, and promotion to secondary students. (3) Faculty and administrators differed significantly on only two sub-factor ratings: employer assisted curriculum development, and faculty workloads. (4) Significant differences in ratings by small program faculty and administrators and large program faculty and administrators were indicated, with most between small program faculty and large program administrators. The study

    The aim of this study was to analyze the very long-term effects of Herbst treatment on tooth position and occlusion. Fourteen patients from a sample of 22 with Class II Division 1 malocclusions consecutively treated with the banded Herbst appliance were reexamined 32 years after therapy. Dental casts were analyzed from before (T1) and after (T2) treatment, and at 6 years (T3) and 32 years (T4) after treatment. Minor changes in maxillary and mandibular dental arch perimeters and arch widths were seen during treatment (T1-T2) and posttreatment (T2-T4). Mandibular incisor irregularity remained, on average, unchanged from T1 to T2 but increased continuously during the 32-year follow-up period (T2-T4). Class II molar and canine relationships were normalized in most patients from T1 to T2. During the early posttreatment period (T2-T3), there was a minor relapse; during the late posttreatment period (T3-T4), molar and canine relationships remained, on average, unchanged. Overjet and overbite were reduced to normal values in all subjects during treatment (T1-T2). After treatment (T2-T4), overjet remained, on average, unchanged, but overbite increased insignificantly. Thirty-two years after Herbst therapy, overall, acceptable long-term results were seen. Stability was found in 64% of the patients for sagittal molar relationships, in 14% for sagittal canine relationships, in 86% for overjet, and in 86% for overbite. A Class II relapse seemed to be caused by an unstable interdigitation of the occluding teeth, a persisting oral habit, or an insufficient retention regimen after treatment. Most posttreatment changes occurred during the first 6 years after treatment. After the age of 20 years, only minor changes were noted. Long-term posttreatment changes in maxillary and mandibular dental arch perimeters and widths as well as in mandibular incisor irregularity seemed to be independent of treatment and a result of physiologic dentoskeletal changes throughout adulthood.

    We present an experience of two years where a group of professors of University in Catania (Italy) and the University of Cordoba (Spain) created a practical case about hydrological planning in the context of similar subjects. The proposed work had to be solved and presented by teams of two students who competed following the philosophy of soccer leagues (national and champion). In the final match, the best teams of each country "played" and defended their work which was judged by an international committee of professors. The presentation and defense was carried out through videoconference so the fans in each country could support their teams. The winners in each country received a certificate of both Universities and the participation in the EGU Assembly 2014 and 2015 as coauthors of the present work. The objective of the practical case is the calculation of design peak flow for a rainfall quantile in a rural catchment following the Curve Number method developed by the Soil Conservation Service (1972.) This type of study implies different disciplines of Hydrology and Soil Sciences and the use of Geographic Information Systems and calculation and programming tools which is very useful to improve the students' technical skills. As for humanistic skills, an oral presentation in English allows improving their knowledge in foreign languages and to face a challenging experience which can be compared with an interview for a job. This teaching experience was very motivating for the students and the professors involved. The results of surveys done by the students indicated the improvement of the level of knowledge about hydrological engineering projects as well as the interest in managing water resources. This type of experience can be useful for other subjects or can integrate more teaching centres. REFERENCES: USDA Soil Conservation Service, 1972. National Engineering Handbook, Section 4, Hydrology.

    Full Text Available The littoral fauna of Maltese sandy and shingle beaches is generally regarded as impoverished and consequently of little conservation interest. The fauna of three sandy and three shingle beaches was systematically sampled by coring, standardised searching and pitfall traps. Diversity and population density were highest at the surface for sandy beaches, but were highest below the surface for shingle. The two beach types had distinct suites of species and individual beaches were faunistically distinct. Maltese sandy and shingle beaches are of conservation importance for their habitat-restricted species, some of which have limited local and regional distributions, and are internationally protected.

    In the east coast of Taiwan, the sort grain size more belongs to cobble or gravel, which is physically distinct compared to the sandy beach in the west coast of Taiwan. Although gravel beaches can dissipate more of wave energy, gravel beaches were eroded and coastal road were damaged especially during typhoons. The purpose of this study is to investigate the geomorphological response of gravel beach due to irregular waves. This experiment was carry out in a 21m long, 50 cm wide, 70 cm high wave tank at Tainan Hydraulics Laboratory, National Cheng-Kung University, Taiwan. To simulate of the geometry in the east coast of Taiwan, a physical model with 1/36 scale-down was used, in which the seawall was 10cm built upon a 1:10 slope and gravel grains with D50 being 3.87 mm was nourished in front of the seawall. In terms of typhoon-scale wave condition, irregular waves with scale-down conditions were generated for 600 s for each scenarios and, three different water levels with respect to the gravel beach are designed. Application of laser combined with image processing to produce 3D topographic map, the erosion zone and accretion zone would be found. The resulting morphological change of gravel beach will be measured using an integrated laser and image processing tool to have 3D topographic maps. It is expected to have more understanding about under what conditions the gravel coasts suffer the least damage. In particular, the relation between erosion rates of gravel beach, the angle of gravel slope and the length of the plane on the gravel slope will be achieved

  13. Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae in a tropical sandy beach, Southeastern Brazil

    Directory of Open Access Journals (Sweden)

    Júlio Guazzelli Gonzalez

    Full Text Available Abstract The feeding ecology of the beach silverside (Atherinella blackburni in the surf zone of a tropical sand beach, located in the southeastern Brazil, was accessed through the gut content analysis of 198 fish. Factors such as fish's size, season and day period were analysed to understand how these variables affect the diet composition of the species. Results show that A. blackburni is a coastal neritic fish with a broad feeding niche. Most recurrent prey were zooplanktonic crustaceans, insects and benthic molluscs, in which Copepoda crustaceans were the dominant dietary item in occurrence and abundance. A. blackburni appears to have a slight ontogenetic shift in its diet, changing from benthic molluscs to crustaceans and insects along its life cycle. The diel activity also reveals to be an important factor to the A. blackburni feeding ecology. The predominant occurrence of small fish during the morning, along with the main preys for this size class, suggests that small individuals use shallower waters as feeding grounds during the morning and, during the night, they move to deeper waters for protection against predators.

    Estimates of past sea-level variations based on different methods and techniques have been presented in a range of studies, including interpretation of beach ridge characteristics. In Denmark, Holocene beach ridge plains have been formed during the last c. 7700 years, a period characterised by both isostatic uplift and changes in eustatic sea-level, and therefore represent an archive of past relative sea-level variations. Here, we present preliminary results from investigation of beach ridges from Feddet, a small peninsula located in Faxe Bay (Baltic Sea) in the eastern part of Denmark. Feddet has been chosen as a key-locality in this project, as it is located relatively close to the current 0-isobase of isostatic rebound. GPR reflection data have been acquired with shielded 250 MHz Sensors & Software antennae along a number of profile lines across beach ridge and swale structures of the Feddet peninsula. Furthermore, topography along the profile lines, primary on beach ridge summits and swale bases, was measured to be included in the interpretation of the GPR reflection data using a high-resolution GPS system. The topography-corrected GPR data allow us to interpret internal sedimentary architecture which may be used as a proxy of past relative sea-level. High-resolution GPR images with a vertical resolution of c. 0.1 m of the near-surface sediments resolve downlapping reflections along the GPR profiles, which are interpreted to mark the transition from the beach to the upper shoreface regime (i.e. sea-level) at the time of deposition. Combining the variations in height of the downlaps (in meters above present mean sea-level) with optically stimulated luminescence dating techniques provides estimates of relative sea-level at specific times.

    The idea for the Students' Cloud Observations OnLine (S'COOL) project as an outreach and education element of NASA's Clouds and the Earth's Radiant Energy System (CERES) research program was conceived in late 1996 during a conversation with a middle school science teacher. S'COOL was implemented in a series of increasingly developed test phases during 1997, as the launch of the first CERES instrument approached. Even before launch, the reception of the project in schools far exceeded expectations. After several delays the first instrument, on the Tropical Rainfall Measuring Mission (TRMM) spacecraft, was launched on Thanksgiving Day, 1997. Since the first launch, development and expansion of the project has continued with expectations for launch of Terra carrying two CERES instruments into a polar orbit in mid-1998. That launch is now expected in fall 1999, and will finally provide overflight of all participating schools. In two years, the project has grown from three initial test participants to over 300 schools now participating in 23 countries on five continents. Students from first grade through university level are involved (most participants are ages 10-15). S'COOL is also being used by a few education professors to teach about Internet use in the classroom. The project continues to grow through word of mouth, presentations at teacher workshops, and now increasingly through teachers who find it during web searches. Participants in the S'COOL project are part of the CERES validation team. They provide ground truth measurements at the time the CERES instrument flies over their location, to be compared with the retrieval of cloud properties by remote sensing from CERES. Quantities reported include cloud type, height, fraction and opacity; information on contrails; surface temperature, pressure and relative humidity; and ground cover (snow/ice, wet, dry; leaves on trees or not). in addition, a comment field on the report form serves as a catch-all for all kinds

    Caloric restriction (CR) is proven to be effective in increasing life span and it is well known that, nutritional habits, sleeping pattern and meal frequency have profound effects on human health. In Ramadan some Muslims fast during the day-light hours for a month, providing us a unique model of intermittent fasting (IF) in humans. In the present study, we have investigated the effects of IF versus CR on the same non-diabetic obese subjects who were followed for two years according to the growth hormone (GH)/Insulin like growth factor (IGF)-1 axis and insulin resistance. Single-arm Interventional Human Study. 23 female subjects (Body Mass Index (BMI) 29-39, aged between 28-42years). Follow-up is designed as 12 months of CR, after which there was a month of IF and 11 months of CR again, to be totally 24 months. Subjects' daily diets were aligned as low calorie diet during CR and during the IF period, the same subjects fasted for 15 hours in a day for a month and there was no daily calorie restriction. Nutritional pattern was changed as 1 meal in the evening and a late supper before sleeping and no eating and drinking during the day light hours in the IF model. Subjects made brisk walking twice a day during the whole follow-up including both CR and IF periods. BMI, Blood glucose, insulin, TSH, GH, HbA1c, IGF-1, Homa-IR and urinary acetoacetate levels were monitored once in three months and twice in the fasting month. While subjects lost 1250 ± 372g monthly during the CR, in the IF period, weight loss was decreased to 473 ± 146 g. BMI of all subjects decreased gradually and as the BMI decreased, glucose, HbA1c, insulin, Homa-IR and TSH levels were decreased. GH levels were at baseline at the beginning, increased in the first six months and stayed steady during the CR and IF period than began decreasing after the IF period, while IGF-I increased gradually during the CR period and beginning with the 7th day of IF period, it decreased and kept on decreasing till the

    The preparation of the soil is the main issue of soil management. Thus, it is also one of the main operations with regard to management of planted forest during the whole productive process. Soil preparation is thought to directly affect various processes of the hydrologic cycle, water erosion, crop productivity and, subsequently, play an important role both for the environment and for the invested capital. Therefore knowledge of the effect of each specific soil management system on forest production is viewed as an essential issue. Based on these considerations, the aim of this work was to quantify soil and water losses by water erosion during the seasons of the year with the highest rainfall intensity in the south hemisphere, i.e. spring and summer in a two year old stand planted with Eucalyptus benthamii. This tree species was planted following three different conditions: 1) soil mechanical preparation in furrows following the land slope, 2) soil mechanical preparation in furrows dug perpendicular to the slope and 3) semi-mechanical preparation by digging an individual hole for each plant. The field experiment was located in Otacílio Costa municipality, SC, Brazil, at the Gropp forest farm owned by the Kablin SA company, 841 m asl altitude. The soil was classified as a "Cambissolo Húmico Alumínico Léptico" according with the Brazilian Soil Classification System with a slope of about 0.12 m m-1. The experimental design consisted of randomly located erosion plots with 3 repetitions, thus a total of 9 plots. The surface area of the plots was 12 x 24 m and they were oriented so that the main side followed the land slope. Suspended sediments and water losses were channelled to collecting tank at the end of the plot. Runoff water and eroded sediments were weakly measured, so that they correspond to cumulative weakly rainfall. The highest soil and water losses were recorded in plots with furrows dug perpendicular to the slope and the lowest ones corresponded to the

    The variation of natural radioactivity along the surface of the beach sands of Camburi, located in Vitoria, capital of Espirito Santo, southeastern Brazil, was determined from the contents of {sup 226}Ra, {sup 232}Th and {sup 40}K. Eleven collecting points was selected along all the 6 km extension of the Camburi beach. Sand samples collected from all established points on January 2011 were dried and sealed in standard 100 mL polyethylene flasks and measured by high resolution gamma spectrometry after a 4 weeks ingrowth period, in order to allow the secular equilibrium in the {sup 238}U and {sup 232}Th series. The {sup 226}Ra concentration was determined from the weighted average concentrations of {sup 214}Pb and {sup 214}Bi. The {sup 232}Th concentration was determined from the weighted average concentrations of {sup 228}Ac, {sup 212}Pb and {sup 212}Bi and the {sup 40}K from its single gamma transition. Preliminary results show activity concentrations varying from 5 Bq.kg{sup -1} to {sup 222} Bq.kg{sup -1} for {sup 226}Ra and from 14 Bq.kg{sup -1} to 1074 Bq.kg{sup -'}1 for {sup 232}Th, both with the highest values for Camburi South and Central. For {sup 40}K, the activity concentrations ranged from 14 Bq.kg{sup -1} to 179 Bq.kg{sup -1} and the highest values were obtained for Camburi South. (author)

    2013-02-01

    A systematic review was undertaken to identify studies describing the global prevalence of breastfeeding up to two years of age or beyond and its effects on child growth and development. The MEDLINE and LILACS databases were searched without any language or date restrictions, retrieving 3,561 titles. All retrieved titles, 453 abstracts and 49 full-text articles were read. Articles with maximum breastfeeding duration of over two years were included. An analysis was carried out of 19 articles that met the inclusion criteria resulting in a combined prevalence of breastfeeding at two years of age of 33 % (95%CI: 0.23; 0.42). Increasing trends towards breastfeeding up to two years of age or beyond were observed in the past decades in South Asia. The six studies analyzing the effects of breastfeeding up to two years of age or beyond on child growth showed contradictory results. No association was found with child development. It is concluded that evidence on the medium-term effects of breastfeeding up to two years of age or beyond is scarce and contradictory. Hence, further research is needed regarding this practice.

  1. Search for Majorana neutrinos with the first two years of EXO-200 data.

    Many extensions of the standard model of particle physics suggest that neutrinos should be Majorana-type fermions-that is, that neutrinos are their own anti-particles-but this assumption is difficult to confirm. Observation of neutrinoless double-β decay (0νββ), a spontaneous transition that may occur in several candidate nuclei, would verify the Majorana nature of the neutrino and constrain the absolute scale of the neutrino mass spectrum. Recent searches carried out with (76)Ge (the GERDA experiment) and (136)Xe (the KamLAND-Zen and EXO (Enriched Xenon Observatory)-200 experiments) have established the lifetime of this decay to be longer than 10(25) years, corresponding to a limit on the neutrino mass of 0.2-0.4 electronvolts. Here we report new results from EXO-200 based on a large (136)Xe exposure that represents an almost fourfold increase from our earlier published data sets. We have improved the detector resolution and revised the data analysis. The half-life sensitivity we obtain is 1.9 × 10(25) years, an improvement by a factor of 2.7 on previous EXO-200 results. We find no statistically significant evidence for 0νββ decay and set a half-life limit of 1.1 × 10(25) years at the 90 per cent confidence level. The high sensitivity holds promise for further running of the EXO-200 detector and future 0νββ decay searches with an improved Xe-based experiment, nEXO.

    Background Preparation for Future Care needs (PFC) has been hypothesized to help older adults adjust to inevitable life and health transitions and thereby decrease the likelihood of developing depression or anxiety. Methods 190 primary care patients aged ≥65 years completed semi-structured research interviews and mail-back surveys at study intake and two years later. Interviews included the Structured Clinical Interview for DSM-IV, the Hamilton Depression Rating Scale, Clinical Anxiety Scale and a measure of PFC. Multiple regression analyses were used to determine the independent association of PFC at intake with depression and anxiety severity at two-year year follow-up. Results Patients who had made more concrete plans at intake were less likely to meet criteria for depression diagnosis at follow-up. They also had lower anxiety severity scores. Patients who had avoided thinking about future care needs had greater depression symptom severity at follow-up. Findings were independent of potential confounds, including illness burden. Conclusions Failure to prepare for future care is a novel putative risk marker for depression and anxiety in older adulthood. Clinicians should be aware that the lack of care planning and frank avoidance may pose a risk for depression and anxiety older their patients. Future research should explore the mechanisms of care planning’s effects on subsequent mood. PMID:21952122

    2014-01-01

    In order to understand the mechanism of beach-to-beach variations in dose rates, measurements at 35 sand beaches were carried out along the Enshu-nada coast (a total of 140km). The sand samples were collected at 10 beaches to obtain the concentrations of potassium, uranium and thorium by means of Ge(Li) spectroscopy. Factors affecting the variation in dose rates were discussed, incorporating these data with data of coastal sea-bottom sediments taken by the Geological Survey of Japan. Two-dimensional measurements were performed at 50 locations each in two beaches near the Tenryu river mouth to know within-beach variations in detail. Contour maps of the data revealed a considerable regularity. It was found from simple analyses of the data collected in this work that the dose rate levels at beaches are affected by the distance from the river mouth, erosion or sedimentation of beach, and depth distribution of seawater.

    Litter washed ashore on the coastline, also called beach litter, constitutes one of the most obvious signs of marine litter pollution. Surveys of beach litter represent a fundamental tool for monitoring pollution in the marine environment and have been used world-wide to classify and quantify marine litter. Identifying the sources of marine and beach litter is, together with education, the prime weapon in combating this type of pollution. This work investigates the impact of three main potential land sources on litter occurrence: urban areas, rivers and beach users. Three sources were analyzed simultaneously on a broad scale (Lazio region, central Italy) using a random sampling design and fitting a generalized linear mixed-effect model. The results show that urban areas are the main drivers for the occurrence of marine litter along central Italy's coastal ecosystems, suggesting that the presence of such litter on Lazio beaches could be effectively reduced by identifying failings in recycling and waste collection procedures and by improving waste processing systems and sewage treatment in urban areas.

    Contamination of sandy beaches of the Baltic Sea in Kaliningrad region is evaluated on the base of surveys carried out from June 2015 to January 2016. Quantity of macro/meso/microplastic objects in the upper 2cm of the sandy sediments of the wrack zone at 13 sampling sites all along the Russian coast is reported. Occurrence of paraffin and amber pieces at the same sites is pointed out. Special attention is paid to microplastics (range 0.5-5mm): its content ranges between 1.3 and 36.3 items per kg dry sediment. The prevailing found type is foamed plastic. No sound differences in contamination are discovered between beaches with high and low anthropogenic load. Mean level of contamination is of the same order of magnitude as has been reported by other authors for the Baltic Sea beaches. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Marine plastic pollution is a global problem with considerable ecological and economic consequences. Quantifying the amount of plastic in the ocean has been facilitated by surveys of accumulated plastic on beaches, but existing monitoring programmes assume the proportion of plastic detected during beach surveys is constant across time and space. Here we use a multi-observer experiment to assess what proportion of small plastic fragments is missed routinely by observers, and what factors influence the detection probability of different types of plastic. Detection probability across the various types of plastic ranged from 60 to 100%, and varied considerably by observer, observer experience, and biological material present on the beach that could be confused with plastic. Blue fragments had the highest detection probability, while white fragments had the lowest. We recommend long-term monitoring programmes adopt survey designs accounting for imperfect detection or at least assess the proportion of fragments missed by observers. Copyright © 2016 Elsevier Ltd.

    We present the case of a windblown beach umbrella inflicting fatal penetrating blunt force to the chest of a 55-year-old female beachgoer. A postmortem examination and detailed case history review were performed which revealed left ventricular trauma, determined to be the cause of death. Using recorded wind speeds from the date of the incident and the weight of the umbrella, we were able to calculate the pressure with which the umbrella struck the victim to be 16,000 PSI. Witness reports, medical records, scene details, and examination of a rental beach umbrella allowed the forensic pathologist to conclude that the object causing this woman's death was a windblown beach umbrella. © 2018 American Academy of Forensic Sciences.

    Haeundae beach is one of the most famous resorts in Korea and plays an important role as a special tourism district. However, the length and width of the beach are being reduced continuously, which would have bad influence on the regional economy and be the financial burden to the local authority considering that a large amount of budget is spent in the beach nourishment annually. Hence, it is necessary to understand the dynamic behavior of sediments in the coast for the systematic preservation plan of coastal environment. Lately a monitoring system using radioactive isotope as tracers is considered as a novel technique in understanding the dynamic transport of sediments. The objective of this study is to investigate the possible variations in sedimentary distribution and quantify the characteristics of sediments using radiotracer.

  13. Alongshore variability in nearshore-beach-dune interaction

    At straight, sandy coasts, wave- and wind-induced processes often lead to the development of an alongshore-variable morphology in the nearshore, beach and dune systems on spatial scales from tens of metres to a few kilometres. Although our understanding of this morphological patterning is quite mature for the different sub-systems, we are only starting to understand how these patterns affect each other across the entire nearshore-beach-dune system. The morphological patterns emerging in subtidal bars often exhibit landward-protruding shallower areas at regular intervals alongshore, known as horns. The alongshore depth variation in these so-called crescentic bars is thought to affect the morphodynamics of the more landward intertidal beach by acting as an alongshore-variable filter for the wave field, both during erosional storm events and the accretionary recovery periods in between storms. Recent studies have revealed that persistent (years - decades) foredune accretion and embryo dune development primarily border wider beach areas, especially along fetch-limited narrow (embryo dunes along wider parts of the beach are less prone to erosion during 'moderate' storms. Although the alongshore variability thus clearly spans the entire nearshore-beach-dune system, this is not reflected in our current understanding of the underlying processes, especially those of beach-dune recovery. In a 15-year data set of planview time-exposure images from Egmond aan Zee, The Netherlands, we observed that the horns of crescentic bars regularly separate from the bar and subsequently migrate onshore towards the beach as a spatially coherent structure, termed Shoreward Propagating Accretionary Waves, or SPAWs. We hypothesize that the onshore welding of these SPAWs results in alongshore variations in intertidal beach width that, in turn, provide alongshore variations in the magnitude of wind-induced transport and dune development. To test this hypothesis, we analysed a data set of Lidar

    Despite their scarcity on a global scale, shingle beaches are a common feature of the coastline ofthe UK, in particular southern England. Shingle beaches have the ability to dissipate large amounts of wave energy over short distances. As a result of this ability, shingle beaches have become a popular 'soft' engineering option for providing protection to coastal regions from the effects of sea flooding and erosion. Shingle beaches are mobile features and, as a result, are subjected to trans...

    Global change introduce a lot of uncertainties concerning future trajectory of beaches by directly or indirectly modifying major driving factors. An improved understanding of the past shoreline evolution may help for anticipate future coastline response. However, in tropical environment, studies concerning carbonate beaches dynamics are scarce compared to open sandy beaches. Consequently, coral reef protected beaches morphological adjustment is still poorly understood and long-term evolution rate are poorly quantified in these specific environment. In this context, La Reunion Island, insular department of France located in Indian Ocean, constitute a favoured laboratory. This high volcanic island possesses 25 km of carbonate beaches which experience hydrodynamic forcing specific from tropical environment: cyclonic swell during summer and long period swell during winter. Because of degraded coral reef health and high anthropogenic pressure, 50% of the beaches are in erosion since 1970s. Beach survey has been conducted since 1990s by scientist and are now encompassed as pilot site within a French observatory network which guarantee long-term survey with high resolution observational techniques. Thus, La Reunion Island is one of the rare carbonate beach to be surveyed since 20 years. This study aims to examined and quantify beach response at decadal scale on carbonate sandy beaches of Reunion Island. The study focus on 12 km of beaches from Cap Champagne to the Passe de Trois-Bassins. The analyze of 15 beach profile data originated from historical and DGPS beach topographic data confirm long term trend to erosion. Sediment lost varies between 0.5 and 2 m3.yr-1 since 1998. However longshore current have led to accretion of some part of beach compartment with rate of 0.7 to 1.6 m3.yr-1. Wave climate was examined from in-situ measurement over 15 years and show that extreme waves associated with tropical cyclones and long period swell play a major role in beach dynamics

    Shoreline changes affect functionality of a sandy beach as a wildlife habitat and coastal erosion is among the primary causes of the changes. We examined temporal shifts in locations where loggerheads placed nests in relation to coastal erosion along a barrier island beach in the northern Gulf of Mexico. We first confirmed consistency in long-term (1855–2001), short-term (1976–2001), and more recent (2002–2012) shoreline change rates in two adjacent beach sections, one historically eroding (west beach) and the other accreting (east beach). The mean annual shoreline change rate in the two sections was significantly different in all time periods. The recent (1998–2012) mean change rate was −10.9 ± 9.9 m/year in the west beach and −2.8 ± 4.9 m/year in the east beach, which resulted in the loss of about 70% and 30% of area in the west and east beaches, respectively. Loggerheads nested significantly closer to the vegetation line in 2012 than in 2002 in the west beach but the difference between the two time periods was not significant in the east beach. However, the distance from nests to the vegetation line from 2002 to 2014 was significantly reduced annually in both beaches; on average, loggerheads nested closer to the vegetation line by 9 m/year in the west beach and 5.8 m/year in the east beach. The observed shoreline change rate and corresponding shift of nest placement sites, combined with the forecasted future beach loss, highlighted the importance of addressing the issue of beach erosion to conserve sandy beach habitats.

    Prevention of sport injuries and illnesses is a focus for epidemiological surveillance. To record and analyse all sports injuries and illnesses registered during the second Asian Beach Games. A descriptive epidemiological study using the International Olympic Committee Surveillance system to register injuries and illnesses during the second Asian Beach Games. The second Asian Beach Games hosted 1132 athletes from 43 countries competing in 14 beach sports. All National Olympic Committees' physicians of the participating teams were invited to report all injuries and illnesses. In addition, medical officers at the different Olympic venues and the main Olympic village reported injuries and illnesses treated at the clinics on a daily basis. A total of 177 injuries were reported equating to an incidence rate of 156.4 per 1000 registered athletes. Tent pegging recorded the highest incidence of injuries with 357 per 1000 registered athletes. The most prevalent injuries were in the foot/toe with 14.1% of all reported injuries. The majority of injuries were incurred during competition (75.4%). In addition, the most common mechanism of injury was contact with another athlete (n=42, 23.7%) and combined sudden and gradual overuse contributed to 30% of the total injury burden. Furthermore, 118 illnesses were reported resulting in an incidence rate of 104.2 illnesses per 1000 registered athletes. The most affected system was the respiratory tract (39.1%) with infection being the most common cause (n=33, 38.0%). The incidence of injury and illness differed significantly among the 14 sports. The data indicate that the risk of injury from beach games is sport dependant. This means that any preventive measures have to be tailored for each discipline. Furthermore, the study showed that respiratory infections are the commonest illness in beach sports and therefore, event organisers should focus improving public health measures and hygiene awareness.

  19. Wave Runup on a Frozen Beach Under High Energy Conditions

    High and mid-latitude beaches have typical morphological characteristics influenced by nearshore processes prevailing under ice conditions during cold season. Nearshore ice complexes (NIC) offer a natural coastal protection by covering beach sediments, while offshore ice-infested waters dissipate incoming waves. Climate change contributes to sea ice shrinking therefore reducing its protection against erosion and flooding. In the Estuary and Gulf of the St. Lawrence (ESL, GSL) (eastern Canada), sea ice cover undergoes an overall shrinking and simulated future projections tend toward a negligible effect on wave climate by 2100. Quantifying the effect of nearshore dynamics on frozen beaches is therefore imperative for coastal management as more wave energy at the coast is expected in the future. To measure the effect of a frozen beach on wave runup elevations, this study employs a continuous video recording of the swash motion at 4Hz. Video-derived wave runup statistics have been extracted during a tidal cycle on a frozen beach, using the Pointe-Lebel beach (ESL) as a test case. Timestack analysis was combined with offshore water levels and wave measurements. A comparison of runup under icy conditions (Dec. 30 2016) with a runup distribution during summer was made under similar high energy wave conditions. Results indicate high runup excursions potentially caused by lowered sediment permeability due to high pore-ice saturation in the swash zone, accentuating the overwash of the eroding coastline and thus the risk of flooding. With projected reduction in coastal sea ice cover and thus higher wave energy, this study suggests that episodes of degradation and weakening could influence the coastal flood risk in mid- and high-latitude cold environments.

  20. Should return to sport be delayed until two years after anterior cruciate ligament reconstruction? Biological and functional considerations

    Science.gov (United States)

    Nagelli, Christopher V.; Hewett, Timothy E.

    2016-01-01

    Anterior cruciate ligament (ACL) tears are common knee injuries sustained by athletes during sports participation. A devastating complication of returning to sport following ACL reconstruction (ACLR) is a second ACL injury. Strong evidence now indicates that younger, more active athletes are at particularly high risk for a second ACL injury and this risk is greatest within the first two years following ACLR. Nearly one-third of the younger cohort that resumes sports participation will sustain a second ACL injury within the first two years after ACLR. The evidence indicates that the risk of second injury may abate over this time period. The incidence rate of second injuries in the first year after ACLR is significantly greater than the rate in the second year. The lower relative risk in the second year may be related to athletes achieving baseline joint health and function well after the current expected timeline (6 to 12 months) to be released to unrestricted activity. This highlights a considerable debate in the return to sport decision process as to whether an athlete should wait until two years after ACLR to return to unrestricted, sports activity. In this review, we present evidence in the literature that athletes achieve baseline joint health and function approximately two years after ACLR. We postulate that delay in returning to sports for nearly two years will significantly reduce the incidence of second ACL injuries. PMID:27402457

    Internationally adopted children are often delayed in their development and demonstrate more behaviour problems than nonadopted children due to adverse preadoption circumstances. This is especially true for children adopted from Eastern European countries. Few studies have focused on children adopted from non-European countries. This paper presents results from an ongoing longitudinal study of 119 internationally adopted children from non-European countries during their first two years in Norway. Several scales measuring different aspects of the children's development are included in the study: communication and gross motor development, temperamental characteristics, and behaviour problems. The results show that internationally adopted children are delayed in their general development when they first arrive in their adoptive families. After two years the children have made significant progress in development. However, they still lag behind in communication and motor skills compared to non-adopted children. The temperamental characteristics seem very stable from time of adoption until two years after adoption. The children demonstrate a low frequency of behaviour problems. However, the behaviour problems have changed during the two years. At time of adoption they show more nonphysically challenging behaviour while after two years their physically challenging behaviour has increased. PMID:22919309

    The aim of this study was to evaluate the outcome two years after arthroscopic subacromial decompression using the Western Ontario Rotator-Cuff (WORC) index and a diagram-based questionnaire to self-assess active shoulder range of motion (ROM). Outcomes in 80 patients with impingement of the shoulder undergoing arthroscopic subacromial decompression were prospectively assessed preoperatively, at three months and at two years post-operatively using the WORC index. All patients had received non-operative treatment for at least six months before undergoing surgery. Active range of motion was measured preoperatively by the examining physician and at two years by the patient him-/herself using a diagram-based questionnaire to self-assess active shoulder ROM. A total of 75 patients (94%), of whom 31 were women, completed the study. The median age was 56 years. In all, 31 patients had additional resection of the acromioclavicular joint. WORC scores improved significantly from preoperatively (median: 1,392) to three months (median: 204) and two years post-operatively (median: 243) (p two years. Arthroscopic subacromial decompression -appears effective in alleviating symptoms in patients with subacromial impingement who are resistant to conservative treatment, but can only be expected to restore normal shoulder function as measured by the WORC in less than 50% of the cases. not relevant. not relevant.

    Even if coastal floods are quite rare events in Sardinia (Italy) at present, they have had dramatic consequences for coastal communities, particularly in conjunction with river flooding. However, flood risk (defined as the product of event probability, vulnerability and value of assets) is expected to increase significantly in the future, due to climate change, defence degradation and sea level rise. Sardinia island has a costal length of approximately 1.900 km including minor neighbouring islands (25% of the entire Italian coasts) and the estimation of the potential exposure of coastal communities to flooding is therefore a critical task. To date methods for achieving this have been based on modelling of coastal inundation using hydrodynamic or GIS-based models of varying complexity. The Dept of Civil and Environmental Engineering and Architecture at the University of Cagliari is carrying out a comprehensive activity of coastal flooding risk mapping at the regional scale within the framework of a scientific collaboration with the Sardinian Regional Authority for the Hydrographic District, that includes monitoring and scientific activities along the entire Sardinian coast. Bathymetry and topographical surveys, sediment characterization, waves and currents measurements, hydrodynamic and morphodynamic modelling are planned, focusing on critical extended areas. In this paper we present an overview of the entire activity programme and give an in-depth account of the ongoing monitoring survey of the dunal system of the Su Giudeu beach (Southern Sardinia, 50 km far from the city of Cagliari). Su Giudeu is a sandy, bay-shaped beach, extending for about 1200 m between two headlands, evolving under waves with a predominant direction of 220-240°N (Scirocco wind). The survey is expected to provide evidence of the response of the remarkable dunal system to wave runup occurring during storm events, to be used in the verification of existing numerical models of dune erosion.

    The purpose of this essay is to present the Praia da Estação (“Beach Station”) movement—an important occupation of public space in Belo Horizonte, Minas Gerais State, Brazil. A joyful protest, Praia da Estação was created in a decentralized and peaceful manner, in response to the top-down regulation set up by Mayor Márcio Lacerda in 2009, to regulate the use of Praça da Estação (“Square Station”). The idea of creating a beach in an inland city, where people would protest in swimsuits, asserts...

    Full Text Available A detailed experimental investigation is been reported on the characterization of beach/river sand for foundry use. Bulk properties of the sand samples collected were evaluated. The experimental results were analyzed as per the American Foundry Society (AFS standard. The analyses show that samples from Ughelli River, Warri River and Ethiope River could be used effectively in the foundry. The sample from Lagos bar beach requires to be sieved properly to remove the coarse fractions in order to make it suitable for foundry use.

    Runup data collected during the summer of 2005 at Ocean Beach, San Francisco, CA are analyzed and considered to be typical summer swash characteristics at this site. Analysis shows that the beach was dissipative with Iribarren numbers between 0.05 and 0.4 and that infragravity energy dominated. Foreshore slopes were mild between 0.01 and 0.05 with swash periods on the order of a minute. Predicted runup heights obtained with six previously developed analytical runup formulae were compared to measured extreme runup statistics. Formulations dependent on offshore wave height, foreshore slope and deep water wavelength gave reasonable results.
