  1. The amusic brain: lost in music, but not in space.

    Directory of Open Access Journals (Sweden)

    Barbara Tillmann

    Full Text Available Congenital amusia is a neurogenetic disorder of music processing that is currently ascribed to a deficit in pitch processing. A recent study challenges this view and claims the disorder might arise as a consequence of a general spatial-processing deficit. Here, we assessed spatial processing abilities in two independent samples of individuals with congenital amusia by using line bisection tasks (Experiment 1 and a mental rotation task (Experiment 2. Both amusics and controls showed the classical spatial effects on bisection performance and on mental rotation performance, and amusics and controls did not differ from each other. These results indicate that the neurocognitive impairment of congenital amusia does not affect the processing of space.

    2002-01-01

    Media coverage of amusement park injuries has increased over the past several years, raising concern that amusement rides may be dangerous. Amusement park fatalities and increases in reported injuries have prompted proposed legislation to regulate the industry. Since 1979, the medical literature has published reports of 4 subdural hematomas, 4 internal carotid artery dissections, 2 vertebral artery dissections, 2 subarachnoid hemorrhages, 1 intraparenchymal hemorrhage, and 1 carotid artery thrombosis with stroke, all related to roller coaster rides. In this article, we review reports of amusement park injuries in the medical literature and Consumer Product Safety Commission data on the overall risk of injury. We also discuss the physics and the physiologic effects of roller coasters that may influence the type and severity of injuries. Although the risk of injury is low, emergency physicians are advised to include participation on thrill rides as part of their history, particularly when evaluating patients presenting with neurologic symptoms.

    One of the leading causes of noise-induced hearing loss is occupational noise exposure; however, little attention has been given to the exposure among amusement ride operators. According to the International Association of Amusement Parks and Attractions, 600,000 ride operators are employed in the U.S. The first objective of this descriptive study was to evaluate if ride operators were exposed to noise levels over 85 dB. The second objective was to classify the ride features that led to the highest noise levels. 136 rides were measured at 17 total amusement parks, county fairs, and festivals in southern Wisconsin and northern Illinois during summer 2015. A sound level meter recorded noise measurements as close in proximity to the ride operator as possible. Each ride was measured for two or three complete ride cycles, which included loading and operating the ride. The sound level meter was programmed to measure noise as recommended by the American Conference of Governmental Industrial Hygienists and with no threshold. 18% of rides measured had projected noise levels greater than American Conference of Governmental Industrial Hygienists recommendation of 85 dB. A repeated measures model was used to analyze the complete ride cycle decibel levels. The model found that traveling carnival rides had significantly higher levels compared to the stationary amusement park rides (p levels than those without midway music (p amusement ride operators would be at risk for noise induced hearing loss and would require a hearing conservation program if the 8-hr time weighted averages were to follow the same trends as the complete ride cycle levels.

    This case study describes the history of an older person, born in 1942 preterminally, who suffered from a brain injury in 2005. Problems in rehabilitation elicited the search for a new meaning in life. In analysing and interpreting the brain injury, preterm birth played a crucial role. The theme of lifelong compensation of deficits, caused by preterm birth, gained new importance. The consequences of brain injury left unsuccessful his former modes of compensation. He was confronted with finding new strategies in order to counterbalance the growing decompensation. This report is based on and was developed through respect for the principles of user involvement in research.

  16. Lost for emotion words: what motor and limbic brain activity reveals about autism and semantic theory.

    Moseley, Rachel L; Shtyrov, Yury; Mohr, Bettina; Lombardo, Michael V; Baron-Cohen, Simon; Pulvermüller, Friedemann

    2015-01-01

    Autism spectrum conditions (ASC) are characterised by deficits in understanding and expressing emotions and are frequently accompanied by alexithymia, a difficulty in understanding and expressing emotion words. Words are differentially represented in the brain according to their semantic category and these difficulties in ASC predict reduced activation to emotion-related words in limbic structures crucial for affective processing. Semantic theories view 'emotion actions' as critical for learning the semantic relationship between a word and the emotion it describes, such that emotion words typically activate the cortical motor systems involved in expressing emotion actions such as facial expressions. As ASC are also characterised by motor deficits and atypical brain structure and function in these regions, motor structures would also be expected to show reduced activation during emotion-semantic processing. Here we used event-related fMRI to compare passive processing of emotion words in comparison to abstract verbs and animal names in typically-developing controls and individuals with ASC. Relatively reduced brain activation in ASC for emotion words, but not matched control words, was found in motor areas and cingulate cortex specifically. The degree of activation evoked by emotion words in the motor system was also associated with the extent of autistic traits as revealed by the Autism Spectrum Quotient. We suggest that hypoactivation of motor and limbic regions for emotion word processing may underlie difficulties in processing emotional language in ASC. The role that sensorimotor systems and their connections might play in the affective and social-communication difficulties in ASC is discussed.

  17. Brain implants for substituting lost motor function: state of the art and potential impact on the lives of motor-impaired seniors.

    2014-01-01

    Recent scientific achievements bring the concept of neural prosthetics for reinstating lost motor function closer to medical application. Current research involves severely paralyzed people under the age of 65, but implications for seniors with stroke or trauma-induced impairments are clearly on the horizon. Demographic changes will lead to a shortage of personnel to care for an increasing population of senior citizens, threatening maintenance of an acceptable level of care and urging ways for people to live longer at their home independent from personal assistance. This is particularly challenging when people suffer from disabilities such as partial paralysis after stroke or trauma, where daily personal assistance is required. For some of these people, neural prosthetics can reinstate some lost motor function and/or lost communication, thereby increasing independence and possibly quality of life. In this viewpoint article, we present the state of the art in decoding brain activity in the service of brain-computer interfacing. Although some noninvasive applications produce good results, we focus on brain implants that benefit from better quality brain signals. Fully implantable neural prostheses for home use are not available yet, but clinical trials are being prepared. More sophisticated systems are expected to follow in the years to come, with capabilities of interest for less severe paralysis. Eventually the combination of smart robotics and brain implants is expected to enable people to interact well enough with their environment to live an independent life in spite of motor disabilities.

    Full Text Available It is very difficult to find the minimum route to travel in amusement park navigation. A searching system for visitors would be useful. Therefore, we constructed a system to find the route with the minimum total traveling time. Facility visitors can employ this system on a smart phone. The system is composed of Java and a Java Servlet. We conclude that our system is useful and can greatly shorten travel time within a typical amusement park.

    The Department of Physics and Astronomy helps host an annual outreach event at a local amusement park for students in grades 6-12. The Physics Night Program is made up of several parts primarily focused on having students apply physics principles and estimate measurements at the park. That evening, DU sponsors undergraduate student volunteers in queue lines to discuss physics concepts with students, and the Society of Physics Student (SPS) chapter stages a more elaborate collection of physics demonstrations at a central gathering place. In 2006, we expanded our outreach efforts to include interactive data collection and on-site interpretation of data. A team of graduate and undergraduate DU SPS students outfitted high school volunteers with vests and hardware designed to return three-axis acceleration information. Students wore the sensors on the rides, returned the equipment to the staging area, and received immediate feedback about the accelerations their hardware recorded. We hope to expand the range of experiential sensing to include more physiological as well as physical data collection, and to provide greater accuracy utilizing the technology we are implementing at the park.

    Mobile device accelerometers are a simple and easy way for students to collect accurate and detailed data on an amusement park ride. The resulting data can be graphed to assist in the creation of force diagrams to help students explain their physical sensations while on the ride. This type of activity can help students overcome some of the conceptual difficulties often associated with understanding centripetal force and typical "elevator-type problems" that are inherent in so many amusement park rides that move, lift, and drop riders. This article provides some sample data and examples from a visit to Six Flags Great America.

    2014-01-01

    About 20 cases of cerebrovascular accidents in amusement parks have been documented. However, only a few cases of amusement park stroke (APS) after roller coaster rides have been reported. Here, we present triggers of stroke, clinical characteristics, and the angiographic appearance of 3 consecutive patients of APS. Their clinical characteristics included young age, absence of atherosclerotic risk factors, and severe injuries. Serial changes in angiographic appearance led to the diagnosis of cervicocephalic artery dissection (CAD). Patients A and B were diagnosed with isolated middle cerebral artery (MCA) dissection, and patient C was diagnosed with internal carotid artery dissection involving MCA dissection. Running excitedly toward an attraction in patient A, a go-kart ride in patient B, and riding in an enhanced motion vehicle in patient C were considered as the likely triggers for APS. We had specific cases with APS associated with CAD, which can occur under diverse contexts other than roller coaster rides at amusement parks. Our findings suggest that the variable directions of the high gravitational forces induced by vehicle riding or running excitedly might injure the MCA or internal carotid artery, and thereby cause CAD in the amusement park.

  8. From amusic to musical?--Improving pitch memory in congenital amusia with transcranial alternating current stimulation.

    Schaal, Nora K; Pfeifer, Jasmin; Krause, Vanessa; Pollok, Bettina

    2015-11-01

    Brain imaging studies highlighted structural differences in congenital amusia, a life-long perceptual disorder that is associated with pitch perception and pitch memory deficits. A functional anomaly characterized by decreased low gamma oscillations (30-40 Hz range) in the right dorsolateral prefrontal cortex (DLPFC) during pitch memory has been revealed recently. Thus, the present study investigates whether applying transcranial alternating current stimulation (tACS) at 35 Hz to the right DLPFC would improve pitch memory. Nine amusics took part in two tACS sessions (either 35 Hz or 90 Hz) and completed a pitch and visual memory task before and during stimulation. 35 Hz stimulation facilitated pitch memory significantly. No modulation effects were found with 90 Hz stimulation or on the visual task. While amusics showed a selective impairment of pitch memory before stimulation, the performance during 35 Hz stimulation was not significantly different to healthy controls anymore. Taken together, the study shows that modulating the right DLPFC with 35 Hz tACS in congenital amusia selectively improves pitch memory performance supporting the hypothesis that decreased gamma oscillations within the DLPFC are causally involved in disturbed pitch memory and highlight the potential use of tACS to interact with cognitive processes.

  10. Categorical Perception of Lexical Tones in Mandarin-speaking Congenital Amusics

    Directory of Open Access Journals (Sweden)

    Wan Ting Huang

    2015-06-01

    Full Text Available Previous research suggests that within Mandarin-speaking congenital amusics, only a subgroup has behavioral lexical tone perception impairments (tone agnosia, whereas the rest of amusics do not. The purpose of the current study was to investigate the categorical nature of lexical tone perception in Mandarin-speaking amusics with and without behavioral lexical tone deficits. Three groups of listeners (controls, pure amusics and amusics with tone agnosia participated in tone identification and discrimination tasks. Indexes of the categorical perception of a physical continuum of fundamental frequencies ranging from a rising to level tone were measured. Specifically, the stimulus durations were manipulated at 100 and 200 ms. For both stimulus durations, all groups exhibited similar categorical boundaries. The pure amusics showed sharp identification slopes and significantly peaked discrimination functions similar to those of normal controls. However, such essential characteristics for the categorical perception of lexical tones were not observed in amusics with tone agnosia. An enlarged step-size from 20 Hz to 35 Hz was not able to produce any discrimination peaks in tone agnosics either. The current study revealed that only amusics with tone agnosia showed a lack of categorical tone perception, while the pure amusics demonstrated typical categorical perception of lexical tones, indicating that the deficit of pitch processing in music does not necessarily result in the deficit in the categorical perception of lexical tones. The different performance between congenital amusics with and without tone agnosia provides a new perspective on the proposition of the relationship between music and speech perception.

    Full Text Available Financial and non-financial reporting concerns in various industries are current challenges. With respect to tourism – the case of amusement parks – the existing research is scarce. In this context, the objectives of our research are the following: (i to identify and critically analyse the key financial and non-financial reporting frameworks applicable in tourism, and respectively (ii to identify the general trend and specific features of the financial and non-financial reporting of companies that manage major amusement parks in Europe. To achieve these objectives, we analysed the most recent sets of annual reports and other reports containing non-financial information, published by a number of five companies that hold the top 20 amusement parks in Europe. We followed a set of non-financial indicators that we selected based on the following reporting frameworks: Global Reporting Initiative (GRI, Sustainability Accounting Standards Board (SASB, European Federation of Financial Analysts (EFFAS, Organisation for Economic Co-operation and Development (OECD, European Tourism Indicators System (ETIS. The results obtained indicate the following existing trends: (i in terms of financial reporting, there is symmetry for four of the 13 analysed aspects, others being reported differently and (ii in terms of non-financial reporting, the degree of symmetry for the information disclosed is much lower that of financial reporting, only two of the 46 selected non-financial indicators (customer satisfaction and number of customers being consistently reported by all the investigated companies.

  6. Spinal Cord Infarction in Hemoglobin SC Disease as an Amusement Park Accident.

    2016-09-01

    Spinal cord infarction (SCI) is extremely rare in children, and only 2 other reports have described the occurrence of SCI in patients with hemoglobin SC disease (HbSC). Amusement park accidents are serious injuries. Patients with preexisting conditions, such as hypertension, cardiac disease, and recent back or neck injuries, may be at an increased risk. We report the case of a 12-year-old girl with HbSC with a past history of only 2 admissions for pain crises, who presented to the emergency department with symptoms of SCI after riding a roller coaster. Fibrocartilaginous embolism (FCE) is an increasingly recognized cause of SCI after events that put strain on the axial skeleton, such as many amusement park rides. Although radiologic criteria for FCE have been proposed, FCE remains a diagnosis of exclusion. To the best of our knowledge, this is the first documented case of SCI in a patient with HbSC and the first case of FCE after an amusement park accident. This case report highlights that HbSC may confound the differential diagnosis of SCI and aims to document an association with FCE in pediatric patients.

    Cultural Heritage all over the world is at high risk. Natural and human activities endanger the current state of monuments and sites, whereas many of them have already been destroyed especially during the last years. Preventive actions are of utmost importance for the protection of human memory and the prevention of irreplaceable. These actions may be carried out either in situ or virtually. Very often in situ preventive, or protective or restoration actions are difficult or even impossible, as e.g. in cases of earthquakes, fires or war activity. Digital preservation of cultural heritage is a challenging task within photogrammetry and computer vision communities, as efforts are taken to collect digital data, especially of the monuments that are at high risk. Visit to the field and data acquisition is not always feasible. To overcome the missing data problem, crowdsourced imagery is used to create a visual representation of lost cultural heritage objects. Such digital representations may be 2D or 3D and definitely help preserve the memory and history of the lost heritage. Sometimes they also assist studies for their reconstruction. An initiative to collect imagery data from the public and create a visual 3D representation of a recently destroyed stone bridge almost 150 years old is being discussed in this study. To this end, a crowdsourcing platform has been designed and the first images collected have been processed with the use of SfM algorithms.

  9. Getting Lost in Tokyo

    Full Text Available This paper explores the potential for using alternative forms of inscriptive practice to describe the urban space of the Tokyo Subway. I begin with an account of the process of getting lost in Shinjuku Subway Station in the heart of Tokyo. This station represents a limit condition of place, being dense and complex beyond the powers of traditional architectural representation. The station is explored through serial translations, beginning with narrative, moving to a flowchart diagram, Laban dance notation, recurring motifs and archetypes, architectural drawing, photography, and cartography. As Claudia Brodsky Lacour and Tim Ingold describe, the form our inscriptive practices take are crucial to the ways in which we conceptualise those places. How much of the experience of a place is lost in the traditional inscriptive practices of the architect? This description of the urban space of the Tokyo subway forms the basis for an extended study exploring the description of this experience of place, and the power of such description to theorise space. The ultimate aim of this is to shift the focus of urban design away from geometric principles and towards the experiences that might be enjoyed in such places.

  10. Nostalgia and lost identity.

    Pourtova, Elena

    2013-02-01

    Nostalgia for the Soviet Union is a major social phenomenon in Russia today due to the irrevocable losses of the recent past in which Soviet citizens involuntarily became immigrants in their own country. With reference to discussions of nostalgia in philosophical and psychoanalytic literature, I suggest that nostalgia may represent either a defensive regression to the past or a progressive striving for wholeness through re-connecting with what has been lost in the service of a greater integration. I compare this with the processes of adaptation seen in immigrants and provide a clinical illustration of a young man coming to terms with loss and change in the post-Soviet era. When nostalgia is recognized as a legitimate emotional experience it may facilitate mourning and enable the integration of the past with the present and the development of a new identity.

    Lost in Translation? Introducing Planetary Boundaries into Social Systems. Fritz Reusswig, Wiebke Lass Potsdam Institute for Climate Impact Research, Potsdam, Germany Identifying and quantifying planetary boundaries by interdisciplinary science efforts is a challenging task—and a risky one, as the 1972 Limits to Growth publication has shown. Even if we may be assured that scientific understanding of underlying processes of the Earth system has significantly improved since then, the challenge of translating these findings into the social systems of the planet remains crucial for any kind of action, and in many respects far more challenging. We would like to conceptualize what could also be termed a problem of coupling social and natural systems as a nested set of social translation processes, well aware of the limited applicability of the language-related translation metaphor. Societies must, first, perceive these boundaries, and they have to understand their relevance. This includes, among many other things, the organization of transdisciplinary scientific cooperation. They will then have to translate this understood perception into possible actions, i.e. strategies for different local bodies, actors, and institutional settings. This implies a lot of 'internal' translation processes, e.g. from the scientific subsystem to the mass media, the political and the economic subsystem. And it implies to develop subsystem-specific schemes of evaluation for these alternatives, e.g. convincing narratives, cost-benefit analyses, or ethical legitimacy considerations. And, finally, societies do have to translate chosen action alternatives into monitoring and evaluation schemes, e.g. for agricultural production or renewable energies. This process includes the continuation of observing and re-analyzing the planetary boundary concept itself, as a re-adjustment of these boundaries in the light of new scientific insights cannot be excluded. Taken all together, societies may well

    In 2012, at the very point where two continents collided, the island of Nuuk disappeared without trace. At the same time, in Brisbane, the 34th International Geological Congress advanced a new era-the Anthropocene: an age where mankind has become a global telluric force. Was the disappearance of Nuuk island a one-off or a direct consequence of the emergence of the Anthropocene? This project was developed during a year of research as an artist-in-residence at LadHyX and has evolved from an expedition of the emergent part of the Mid-Atlantic ridge and the region of deep oceanic water dive. This talk will present Lost In fathoms a narratives composed of installations, drawings and photographs by the means of which we investigate the causes involved in the disappearance of Nuuk island. It challenges the perception of oceanic and geologic time scales and human's impact on the environment. This project is exhibited from October 16th to November 29th 2014, at GV Art Gallery in London, a contemporary art gallery devoted to art and science shows.

    Lost circulation is the loss of drilling fluid from the wellbore to fractures or pores in the rock formation. In geothermal drilling, lost circulation is often a serious problem that contributes greatly to the cost of the average geothermal well. The Lost Circulation Technology Development Program is sponsored at Sandia National Laboratories by the US Department of Energy. The goal of the program is to reduce lost circulation costs by 30--50% through the development of mitigation and characterization technology. This paper describes the technical progress made in this program during the period April 1991--March 1992. 8 refs.

Little Bobby Missoula is going to turn ten tomorrow and his parents have promised to take him to Outlandish Adventures, an amusement park that Bobby has seen advertised on television. As Bobby drifts off to sleep, he begins to dream about the fun that he will have on his birthday. He dreams about the smell of cotton candy and the yells of carnies soliciting people in to play their games, but most of all, he dreams about the Lightning Bolt - the tallest, fastest, and scariest roller coaster that little Bobby has ever seen. In his dream, the Lightning Bolt whips Bobby around sharp angles, through upside down loops so close to water that Bobby’s hair and face get wet, down vertical descents at speeds over 100 miles per hour, and finally to an abrupt stop where Bobby rushes to the end of the line to do it all over again.

  19. Predators of knowledge construction: Interpreting students' metacognition in an amusement park physics program

    Anderson, David; Nashon, Samson

    2007-03-01

    It is recognized widely that learning is a dynamic and idiosyncratic process of construction and reconstruction of concepts in response to new experiences. It is influenced by the learner's prior knowledge, motivation, and sociocultural context. This study investigated how year 11 and 12 physics students' metacognition influences the development of their conceptual understandings of kinematics. An interpretive case study approach was used to investigate students working in collaborative groups in the context of an amusement park physics program. The metacognitive character of individual learners was demonstrated to have a strong influence on their conceptual development. Moreover, the metacognitive character of individuals within the small group contexts investigated was a key factor influencing the groups' collective knowledge development. A coyote-rabbit metaphor was developed to interpret the resilience and weaknesses of individual and group knowledge construction processes, and elucidates new theoretical understandings regarding metacognition and its influence on knowledge construction.

    Water management in urban areas of developing countries is a major environmental challenge for the future. Within the framework of the IWA Cities of the Future Programme, current water and wastewater management systems are investigated in Kayseri, Turkey, with the purpose of bringing water into the center of city life by a reformed pilot project. In order to assess both the quantity and dynamics of water to be utilized in the Kayseri Amusement Park, the US Environmental Protection Agency's (US EPA) Storm Water Management Model (SWMM) 5.0 was used. The obtained results demonstrated that after 3 years, 38,039 m(3) of rainwater could be stored in the two proposed underground storage tanks. Forty three per cent of the water-ski lake with a volume of 90,000 m(3) could be recharged with the stored rainwater.

    The optical light profiles of nearby early type galaxies are known to exhibit a smooth transition from nuclear light deficits to nuclear light excesses with decreasing galaxy mass, with as much as 80 per cent of the galaxies with stellar masses below 10^10 Msun hosting a massive nuclear star cluster. At the same time, while all massive galaxies are thought to harbor nuclear super-massive black holes (SMBHs), observational evidence for SMBHs is slim at the low end of the mass function. Here, we explore the environmental dependence of the nucleation fraction by comparing two homogeneous samples of nearby field vs. cluster early type galaxies with uniform Hubble Space Telescope (HST) coverage. Existing Chandra X-ray Telescope data for both samples yield complementary information on low-level accretion onto nuclear SMBHs. Specifically, we report on dual-band (F475W & F850LP) Advanced Camera for Surveys (ACS) imaging data for 28 out of the 103 field early type galaxies that compose the AMUSE-Field Chandra surv...

    2013-01-01

    This study was conducted to help better understand the current sodium intake of Korean children and to establish children's good eating habits through investigation of the sodium content of ready-to-eat foods collected from nine major amusement parks in Korea. The sodium content of a total of 322 products was analysed by using ICP and then the potential risk based on the recommended daily intake of sodium as described in the Korean dietary reference intakes was determined. The results showed that sodium content was the lowest in muffins (245 mg/100 g) and the highest in seasoned dried filefish (1825 mg/100 g). The average amounts of sodium per serving of seasoned dried filefish, tteokbokki and fish paste were 1150, 1248 and 1097 mg, respectively. The values were above 50% of the daily intake of sodium recommended by the Korean dietary reference intake. The ready-to-eat foods were also classified into high, medium and low sodium content on the basis of standards recommended by the Korean Food and Drug Administration. Most snacks were classified as high sodium foods because they exceeded "300 mg (84.5% of the total daily allowance)". Furthermore, the meal substitution foods such as kimbab, tteokbokki, mandus, sandwiches and hamburgers exceeded "600 mg (90.3% of the total daily allowance)" and were also classified as high sodium foods. In addition, ready-to-eat foods in amusement parks are similar to foods eaten on streets and foods around school zones, which contain high sodium content; thus, the intake frequency might be high, which would induce high risk to children health. Koreans already consume a high amount of sodium daily via their usual diets. So, the sodium content in snacks and substitution foods needs to be reduced. Consequently, this study noted that parents and guardians should carefully consider their children's consumption of ready-to-eat foods from Korean amusement parks.

    Geologic and mineral-resource investigations identified no mineral-resource potential in the Lost Creek Roadless Area, California. Sand and gravel have been mined from alluvial flood-plain deposits less than 1 mi outside the roadless area; these deposits are likely to extend into the roadless area beneath a Holocene basalt flow that may be as much as 40 ft thick. An oil and gas lease application which includes the eastern portion of the roadless area is pending. Abundant basalt in the area can be crushed and used as aggregate, but similar deposits of volcanic cinders or sand and gravel in more favorable locations are available outside the roadless area closer to major markets. No indication of coal or geothermal energy resources was identified.

    We review our attempts to discover lost baryons at low redshift with ``X-ray forest'' of absorption lines from the warm-hot intergalactic medium. We discuss the best evidence to date along the Mrk 421 sightline. We then discuss the missing baryons in the Local Group and the significance of the z=0 absorption systems in X-ray spectra. We argue that the debate over the Galactic vs. extragalactic origin of the z=0 systems is premature as these systems likely contain both components. Observations with next generation X-ray missions such as Constellation-X and XEUS will be crucial to map out the warm-hot intergalactic medium.

    2013-01-01

    We perform a series of simulations of evolving star clusters using AMUSE (the Astrophysical Multipurpose Software Environment), a new community-based multi-physics simulation package, and compare our results to existing work. These simulations model a star cluster beginning with a King model distribution and a selection of power-law initial mass functions, and contain a tidal cut-off. They are evolved using collisional stellar dynamics and include mass loss due to stellar evolution. After determining that the differences between AMUSE results and prior publications are understood, we explored the variation in cluster lifetimes due to the random realization noise introduced by transforming a King model to specific initial conditions. This random realization noise can affect the lifetime of a simulated star cluster by up to 30%. Two modes of star cluster dissolution were identified: a mass evolution curve that contains a run-away cluster dissolution with a sudden loss of mass, and a dissolution mode that does n...

    2014-10-01

    Full Text Available This paper combines sociological perspectives on family display, internet studies on family and private photography and a child studies perspective on the display of children. The paper proposes that blogging practices related to visits to theme and amusement parks in Sweden provide a new arena for people to display family-like relationships. In the different displays, adults mainly use pictures of children in the blogs to demonstrate their ability to perform family-like relationships. The paper suggests that this form of child-centred display, a visualized child-centredness, done during the park visit as well as in the blogging, is part of the construction of contemporary childhoods and what it means to be a child today and has not been theorized in earlier research on the display of family-like relations.

    Maurice Ravel had been subject to psychiatric disorder for many years when signs of organic brain disease appeared at the age of 52. Aphasia, apraxia, agraphia, and alexia became established some five years later. Musical creativity was lost. Alajouanine diagnosed cerebral atrophy with bilateral ventricular enlargement. Though Ravel's condition deteriorated progressively, generalised dementia was not apparent. He died in December 1937, after a craniotomy performed by Clovis Vincent, possibly from a subdural haematoma. Vincent's operative findings are described here. The likely cause of Ravel's illness was a restricted form of cerebral degeneration.

    Full Text Available In his intertextual and metatextual novel, J. Fforde does not propose a specific, coherent interpretation of Jane Eyre: his parody is more an “amusing critical experiment”, a playful narrative in which Charlotte Brontë’s romance is brought to life in a way that allows every reader to deal with such critical issues in Jane Eyre as point of view, the controversial ending and the creation of characters.

    2013-08-01

    Full Text Available Williams syndrome (WS, a genetic, neurodevelopmental disorder, is of keen interest to music cognition researchers because of its characteristic auditory sensitivities and emotional responsiveness to music. However, actual musical perception and production abilities are more variable. We examined musicality in WS through the lens of amusia and explored how their musical perception abilities related to their auditory sensitivities, musical production skills, and emotional responsiveness to music. In our sample of 73 adolescents and adults with WS, 11% met criteria for amusia, which is higher than the 4% prevalence rate reported in the typically developing population. Amusia was not related to auditory sensitivities but was related to musical training. Performance on the amusia measure strongly predicted musical skill but not emotional responsiveness to music, which was better predicted by general auditory sensitivities. This study represents the first time amusia has been examined in a population with a known neurodevelopmental genetic disorder with a range of cognitive abilities. Results have implications for the relationships across different levels of auditory processing, musical skill development, and emotional responsiveness to music, as well as the understanding of gene-brain-behavior relationships in individuals with WS and typically developing individuals with and without amusia.

    Carolina bays are shallow wetland depressions found only on the Atlantic Coastal Plain. Although these isolated interstream wetlands support many types of communities, they share the common features of having a sandy margin, a fluctuating water level, an elliptical shape, and a northwest to southeast orientation. Lost Lake, an 11.3 hectare Carolina bay, was ditched and drained for agricultural production before establishment of the Savannah River Site in 1950. Later it received overflow from a seepage basin containing a variety of chemicals, primarily solvents and some heavy metals. In 1990 a plan was developed for the restoration of Lost Lake, and restoration activities were complete by mid-1991. Lost Lake is the first known project designed for the restoration and recovery of a Carolina bay. The bay was divided into eight soil treatment zones, allowing four treatments in duplicate. Each of the eight zones was planted with eight species of native wetland plants. Recolonization of the bay by amphibians and reptiles is being evaluated by using drift fences with pitfall traps and coverboard arrays in each of the treatment zones. Additional drift fences in five upland habitats were also established. Hoop turtle traps, funnel minnow traps, and dip nets were utilized for aquatic sampling. The presence of 43 species common to the region has been documented at Lost Lake. More than one-third of these species show evidence of breeding populations being established. Three species found prior to the restoration activity and a number of species common to undisturbed Carolina bays were not encountered. Colonization by additional species is anticipated as the wetland undergoes further succession.

  5. The lost art of finding our way

    Huth, Edward John

    2013-01-01

    Long before GPS, Google Earth, and global transit, humans traveled vast distances using only environmental clues and simple instruments. John Huth asks what is lost when modern technology substitutes for our innate capacity to find our way. Encyclopedic in breadth, weaving together astronomy, meteorology, oceanography, and ethnography, The Lost Art of Finding Our Way puts us in the shoes, ships, and sleds of early navigators for whom paying close attention to the environment around them was, quite literally, a matter of life and death. Haunted by the fate of two young kayakers lost in a fogbank off Nantucket, Huth shows us how to navigate using natural phenomena—the way the Vikings used the sunstone to detect polarization of sunlight, and Arab traders learned to sail into the wind, and Pacific Islanders used underwater lightning and “read” waves to guide their explorations. Huth reminds us that we are all navigators capable of learning techniques ranging from the simplest to the most sophisticated skil...

  7. Lost City and the Search For Life

    Science.gov (United States)

    Kelley, D. S.

    2014-12-01

    Since their discovery in 1979, high-temperature hot springs fueled by submarine volcanoes have served as models in the search for life elsewhere in the solar system. The early recognition of hot microbial biospheres associated with active volcanism along global mid-ocean ridges fundamentally shifted concepts of how planets and life co-evolve. These metal-rich, acidic systems were thought to represent the most extreme conditions on Earth, hosting novel life based on chemosynthesis. In 2000, this paradigm was profoundly impacted by the discovery of the Lost City hydrothermal field, characterized by conditions never before seen. Here, 60 m-tall limestone chimneys vent pH 10-11, metal-poor, 90°C fluids rich in hydrogen and abiotically-produced methane and formate. The fluid chemistry is driven, not by volcanic heat, but by fluid-rock reactions in underlying ultramafic basement at up to ~ 200°C. These peridotite-hosted biotopes differ significantly from volcanic-hosted vent systems in which carbon dioxide is a dominant volatile species. Instead, serpentinzation reactions yield high hydrogen and low molecular-weight hydrocarbons that result in energy-rich habitats with cell concentrations that reach 109cells/gram carbonate. The absence of volcanism, and on-going serpentinization reactions result in a remarkably stable system with venting active for >150,000 years. With the discovery of Lost City, it is clear that high temperature volcanic activity is not a prerequisite for life. Exothermic serpentinization reactions occur under a wide-range of temperatures and can result in up to a 40% volume of expansion, which may both close and open fractures. Hence, Lost City may serve as a model in the search for life on other planets and moons with rocky, undifferentiated terranes and overlying oceans. Within such systems, interior cooling, coupled with tidally-induced heating may induce hydrothermal flow, and perhaps life-sustaining environments in the absence of volcanism.

    2011-01-01

    The paper presents a new hidden data insertion procedure based on estimated probability of the remaining time of the call for steganographic method called LACK (Lost Audio PaCKets steganography). LACK provides hidden communication for real-time services like Voice over IP. The analytical results presented in this paper concern the influence of LACK's hidden data insertion procedures on the method's impact on quality of voice transmission and its resistance to steganalysis. The proposed hidden data insertion procedure is also compared to previous steganogram insertion approach based on estimated remaining average call duration.

    Valenzuela, David; Loewe, Marcelo; Raya, Alfredo

    2016-01-01

    We explore the problem of atomic collapse in graphene by monopole impurities, both electric and magnetic, within the context of supersymmetric quantum mechanics. For electric impurities, upon factorizing the radial Dirac Hamiltonian and identifying the supercharges, existence of a critical charge that makes the ground state {\\em fall-into-the-center} translates into lost of unitarity for the corresponding Hamiltonian. For the problem of magnetic monopole impurities, preservation of unitarity for all values of the parameters of the corresponding potential translates into the absence of atomic collapse in this case.

  11. Finding long-lost Comet Lexell

    2015-11-01

    Comet D/1770 L1 (Lexell) made the closest observed pass by a comet to the Earth at approximately 0.015 AU on 1 July 1770. A naked-eye object observed by many astronomers of the time, it was subsequently lost: the best contemporary estimates had it removed from its 1770 orbit by Jupiter in 1779 and sent to the outer Solar System.Near-Earth asteroid 2010 JL33 has an orbit similar to that followed by Lexell's comet during its observed apparition. However, this NEA's nominal orbit, which is well-known on the basis of a decade-long arc which includes radar observations, does not approach the Earth at the correct time to be Lexell's comet. That is, unless modest non-gravitational forces are applied, in which case the famous near-miss can be reproduced.Modern measurements of 2010 JL33 together with those Lexell's comet made in the 18th century -which include motion exceeding 40 degrees per day on the sky at closest approach- provide exquisite constraints on the dynamical processes at work, cometary, Yarkovsky or other. I will discuss the implications of and the conditions required for asteroid 2010 JL33 to be, in fact, long-lost comet Lexell.

  12. Ben Franklin's Scientific Amusements

    Herschbach, Dudley

    2003-04-01

    As an American icon, Benjamin Franklin is often portrayed as wise and canny in business and politics, earnestly pursuing and extolling diligence, sensible conduct, pragmatism, and good works. Also legendary are some of his inventions, particularly the lightning rod, bifocals, and an efficient wood-burning stove. The iconic image is misleading in major respects. Today, surprisingly few people appreciate that, in the 18th century, Franklin was greatly esteemed throughout Europe as a scientist (termed then a "natural philosopher.") He was hailed as the "Newton of Electricity." Indeed, until Franklin, electricity seemed more mysterious than had gravity in Newton's time, and lightning was considered the wrath of God. By his own account, Franklin's studies of electricity and many other phenomena were prompted not by practical aims, but by his playful curiosity--which often became obsessive. Also not generally appreciated is the importance of Franklin's scientific reputation in enhancing his efforts to obtain French support for the American Revolution.

  17. Sociology: a lost connection in social psychology.

    Oishi, Shigehiro; Kesebir, Selin; Snyder, Benjamin H

    2009-11-01

    For the first half of the 20th century, sociology was one of the closest allies of social psychology. Over the past four decades, however, the connection with sociology has weakened, whereas new connections with neighboring disciplines (e.g., biology, economics, political science) have formed. Along the way, the sociological perspective has been largely lost in mainstream social psychology in the United States. Most social psychologists today are not concerned with collective phenomena and do not investigate social structural factors (e.g., residential mobility, socioeconomic status, dominant religion, political systems). Even when the social structural factors are included in the analysis, psychologists typically treat them as individual difference variables. Sociologist C. Wright Mills famously promoted sociological imagination, or the ability to see distal yet important social forces operating in a larger societal context. By comparing sociological perspectives to psychological perspectives, this article highlights the insights that the sociological perspective and sociological imagination can bring to social psychology.

    The first scene opens with the music of Shirley Bassey. The astronomer Henrietta Swan Leavitt is writing a diary when visited by the famous CBS reporter Edward Roscoe Murrow. Henrietta is surprised that this American television channel should want to pay such a tribute to her, but she agrees to be interviewed. Annie Jump Cannon, her friend and colleague from Harvard College Observatory, accompanies her during most of the sessions. Everything goes so well that the journalist tries to touch on certain issues that Henrietta seems to want to keep secret, such as her relationship with Edward Charles Pickering, Director of the Observatory, and the reason why she failed to get the recognition for her work that she deserved.This is the argument of the play The Lost Honor of Henrietta Leavitt, a project of the Museo de la Ciencia y el Cosmos (Museum of Science and the Cosmos), run by the Organismo Autonomo de Museos y Centros of Cabildo de Tenerife (Autonomous Organism of Museums and Centres of the island government, Cabildo of Tenerife), with funding from the Spanish Foundation for Science and Technology (FECYT) and designed for the International Year of Astronomy 2009. The play, written and directed by the author, Carmen del Puerto, has been staged eight times in Tenerife and Pamplona. The poster values this experience as a resource for scientific popularization.

  1. America’s Lost Innocence and Cinema

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available In my paper America’s Lost Innocence I intend to focus on American cinema of the ’50s, part of ’60s, and contemporary throwbacks to those decades. The ’50s have been called “the last decade of American innocence”, “the happiest decade in America’s history – when things were going on – that everybody misses” (by Jean Baudrillard. That era symbolically ceased on 22 November 1963; however, many scholars and publicists undermine the belief in its very existence. Michael Wood calls the ’50s a time of “self-deception”; therefore, the question raised is – has America ever been innocent? By concentrating on the message conveyed by mostly genre (e.g. drama, melodrama, musical, romantic comedy and mainstream movies made in the ’50s and early ’60s (e.g. A Place In the Sun, Cat on the Hot, Tin Roof, Home From the Hill, I intend to analyze the portrait of American society of that time, it’s rules and expectations towards individuals and system as a whole. In the second part of my paper I will focus on contemporary throwbacks to those times depicted mostly in movies made in the 21st century, although not exclusively (e.g. Far From Heaven, The Hours, Revolutionary Road, the TV series Mad Men [2007–], Pleasantville. Using those and other movies as examples, I intend to prove the thesis that the phenomenon of retro and contemporary retromania are not always and not by definition conservative, and can serve as a means to a critical approach towards society.

    Laleh Atashi

    2011-01-01

    Full Text Available The story of the loss of paradise has been read and interpreted in different ages. Commentary on Milton's Paradise Lost is not limited to verbal texts; painters and illustrators have contributed greatly to the poem by presenting their own time-bound readings and interpretations of the poem through their illustrations that are far beyond mere decorations. John Martin, in the aftermath of the Industrial Revolution, deletes the Father and the Son from his illustrations. Only angels such as Raphael are the representations of deity and are as powerless and tiny as Adam and Eve. Adam and Eve, after the Fall seem as small, powerless and as subjugated to the natural surrounding as they were before the Fall. Satan is the only powerful figure in his elegant palace. Through a new historical outlook, the researchers aim at exposing the workings of ideology and dominant discourses that informed John Martin's pictorial reading of Milton's poem in the early 19th century

    A general thermodynamic analysis is given of dissipative self-assembly (DSA). Subsequently, the analysis is used to quantify the lost work in a recently published chemical realization of DSA (Boekhoven et al., Angew Chem Int Ed 49:4825, 2010) where a formation reaction produces the monomers that subsequently self-assemble and are finally annihilated by means of a destruction reaction. For this example, the work lost in self-assembly itself is found to be negligibly small compared to the work lost in the reactions driving the non-spontaneous formation reaction and the kinetically hindered destruction reaction.

Modern imaging techniques have identified a second long association tract between the temporal and prefrontal language zones, taking a ventral course along the extreme capsule. This newly identified ventral tract connects brain regions needed for language comprehension, while the well-known arcuate fascicle is used for "sensorimotor mapping" during speech production. More than 130 years ago, Carl Wernicke already described a ventral connection for language, almost identical to the present results, but during scientific debate in the following decades either its function or its existence were rejected. This article tells the story of how this knowledge was lost and how the ventral connection, and in consequence the dual system, fits into current hypotheses and how language relates to other systems.

    Initial efforts in the study were focused on identifying potential lost opportunities. Results of these efforts resulted in the following measures being identified as potential lost opportunities in the irrigation sector: pumping plant efficiency improvements on both existing and new sprinkler irrigated acres, low-pressure irrigation on new sprinkler acres, and mainline modification and fittings redesign on new sprinkler acres. All of these potential lost opportunities except fittings design were subject to more detailed analyses through a survey of irrigation equipment dealers, pump repairers and country extension agents. Fittings design was omitted from the survey. Results of the survey indicated that only high-efficiency electric motors and correct pump selection methods on existing and new sprinkler systems and low-pressure irrigation on new handmove/sideroll systems should be considered lost opportunities.

    The term idiopathic focal epilepsies of childhood (IFE) is not formally recognised by the ILAE in its 2010 revision (Berg et al., 2010), nor are its members and boundaries precisely delineated. The IFEs are amongst the most commonly encountered epilepsy syndromes affecting children. They are fascinating disorders that hold many "treats" for both clinicians and researchers. For example, the IFEs pose many of the most interesting questions central to epileptology: how are functional brain networks involved in the manifestation of epilepsy? What are the shared mechanisms of comorbidity between epilepsy and neurodevelopmental disorders? How do focal EEG discharges impact cognitive functioning? What explains the age-related expression of these syndromes? Why are EEG discharges and seizures so tightly locked to slow-wave sleep? In the last few decades, the clinical symptomatology and the respective courses of many IFEs have been described, although they are still not widely appreciated beyond the specialist community. Most neurologists would recognise the core syndromes of IFE to comprise: benign epilepsy of childhood with centro-temporal spikes or Rolandic epilepsy (BECTS/RE); Panayiotopoulos syndrome; and the idiopathic occipital epilepsies (Gastaut and photosensitive types). The Landau-Kleffner syndrome and the related (idiopathic) epilepsy with continuous spikes and waves in sleep (CSWS or ESES) are also often included, both as a consequence of the shared morphology of the interictal discharges and their potential evolution from core syndromes, for example, CSWS from BECTS. Atypical benign focal epilepsy of childhood also has shared electro-clinical features warranting inclusion. In addition, a number of less well-defined syndromes of IFE have been proposed, including benign childhood seizures with affective symptoms, benign childhood epilepsy with parietal spikes, benign childhood seizures with frontal or midline spikes, and benign focal seizures of adolescence.

    Objective: The present study, by comparing amusics with matched controls, aimed to find out whether the deficit in music perception has already extended to speech in Chinese amusics, and whether emotional semantics could compensate this kind of disorder in pitch perception. Methods: 20 amusics and 22 controls were selected after MBEA. Then using event-related potential technique, we assessed whether the amusics of Mandarin Chinese had difficulties in discriminating the Chinese emotional words by analyzing the behavioral data and electrophysiological index. Results: Controls performed better in both speech and non-speech stimuli tonal discriminating tasks and both groups showed better in speech stimuli tonal discriminating task. Furthermore, the only difference between the two groups in tonal discriminating task occurred in positive slow wave. According to the scalp topography, amusics showed an asymmetry in the right frontal-central region. Conclusion: Although Chinese amusics are familiar with tonal language, but their pitch perception disorder has extended to speech domain, while the emotional semantics cannot compensate the deficit in pitch perception. There is no dysfunction in auditory cortex in amusics, and their deficit in pitch perception is related to the lack of investment in cognitive resources.%目的:探讨患有失歌症的汉语使用者其音高加工上的障碍是否延伸到了言语领域,情绪语义能否弥补其在言语音高知觉上的不足.方法:通过蒙特利尔失歌症成套测验(MBEA)筛选失歌症组被试20人和正常对照组被试22人,并采用ERPs技术进行言语刺激和非言语刺激语调分辨任务实验,以分析两组被试在音调分辨能力和电生理指标上的差异.结果:对照组对言语和非言语刺激的音调分辨能力都显著优于失歌症组,且无论是失歌症组还是对照组,其在言语刺激音调分辨任务中的表现都要优于在非言语刺激音调分辨任务中的表现.

  2. Static slot testing of conventional lost circulation materials

    1983-01-01

    A study of the utility of conventional lost circulation materials and testing methods was performed using a modified API slot tester. Five lost circulation materials were evaluated in 266 tests at both room temperature and temperature-aged conditions simulating expected geothermal environments. A large variation in the maximum pressure (or sealing pressure) the plug could withstand was attributed to nonrepeatability in plug strengths. Plugs were composed to multiple or single particle bridges, with the latter providing stronger, better sealing plugs. Seals occurred on the upstream surface of the slots in all cases. Sealing pressures generally decreased with increasing slot widths and decreasing solids concentration. When the slot width was less than the size of the largest rigid particle in the lost circulation slurry, sealing pressure was maximized. When the slot width was greater than three times the maximum rigid particle size, no significant sealing ability was observed with the conventional materials tested. Additionally, cellulosic lost circulation materials are severely degraded by temperature aging. Mud gellation provided no significant improvement in lost circulation material sealing ability.

    Based on the characteristics of the lost foam casting (LFC) and the artificial neural network technique, a mathematicalmodel for the simulation of the melt-pattern interface movement during the mold filling of LFC has been proposed andexperimentally verified. The simulation results are consistent with the experiments in both the shapes of melt frontand filling sequences. According to the calculated interface locations, the fluid flow and the temperature distributionsduring the mold filling and solidification processes were calculated, and the shrinkage defect of a lost foam ductileiron casting was predicted by considering the mold wall movement in LFC. The simulation method was applied tooptimize the casting design of lost foam ductile iron castings. It is shown that the model can be used for the defectsprediction and for casting design optimization in the practical LFC production.

    Full Text Available Qualitative human resources remain one of the main problem of Eastern Europe and in particular Western Balkan countries. After 20 years of deep economic, political and social transformation, those countries are facing the problem of the highly qualified human resources they lost in these two decades, while in most of cases there is no a real measurement of the weight and impact these phenomena of Brain Drain has in the quality of the work force. Most of them are trying to set up and apply Brain Gain strategies at a national level. The paper aims to analyze and evaluate the influence that the missing of a previous qualitative and quantitative evaluation of the Phenomena of Brain Drain in Albania, has in the successful application of the Brain Gain strategy. The research objective will be fulfilled by analyzing the evolution of the Brain Drain phenomena, by an introduction of the Albanian characteristic and shape of  Brain Drain from 1990, by analyzing the Brain Gain strategy applied in the country comparing it to a successful application. The paper analyzes factors and variables which may affect the successful application of Brain Gain in Albania while  evidences the importance of stakeholder approach in objectives and aims of Brain Gain program and strategy and the use of the  Balance Scorecard as a strategic management system in “brain gain” strategy set up and application in the case of Albania and those of other countries of the region as well.

    2010-12-01

    In 2010 the High Court of Australia in Tabet v Gett (2010) 240 CLR 537 determined an appeal in a medical negligence case concerning a six-year-old girl who had presented to a major paediatric hospital with symptoms over several weeks of headaches and vomiting after a recent history of chicken pox. The differential diagnosis was varicella, meningitis or encephalitis and two days later, after she deteriorated neurologically, she received a lumbar puncture. Three days later she suffered a seizure and irreversible brain damage. A CT scan performed at that point showed a brain tumour. As Australia does not have a no-fault system providing compensation to cover the long-term care required for such a condition, the girl (through her parents and lawyers) sued her treating physician. She alleged that, because a cerebral CT scan was not performed when clinically indicated after the diagnosis of meningitis or encephalitis and before the lumbar puncture, she had "lost the chance" to have her brain tumour treated before she sustained permanent brain damage. She succeeded at first instance, but lost on appeal. The High Court also rejected her claim, holding unanimously that there were no policy reasons to allow recovery of damages based on possible (less than 50%) "loss of a chance" of a better medical outcome. The court held that the law of torts in Australia required "all or nothing" proof that physical injury was caused or contributed to by a negligent party. The High Court, however, did not exclude loss of chance as forming the substance of a probable (greater than 50%) claim in medical negligence in some future case. In the meantime, patients injured in Australia as a result of possible medical negligence (particularly in the intractable difficult instances of late diagnosis) must face the injustice of the significant day-to-day care needs of victims being carried by family members and the taxpayer-funded public hospital system. The High Court in Tabet v Gett again provides

    Galbreath, D. (Green Mountain International, Waynesvile, NC); Mansure, Arthur James; Bauer, Stephen J.

    2004-12-01

    We have concluded a laboratory study to evaluate the survival potential of polymeric materials used for lost circulation plugs in geothermal wells. We learned early in the study that these materials were susceptible to hydrolysis. Through a systematic program in which many potential chemical combinations were evaluated, polymers were developed which tolerated hydrolysis for eight weeks at 500 F. The polymers also met material, handling, cost, and emplacement criteria. This screening process identified the most promising materials. A benefit of this work is that the components of the polymers developed can be mixed at the surface and pumped downhole through a single hose. Further strength testing is required to determine precisely the maximum temperature at which extrusion through fractures or voids causes failure of the lost circulation plug.

    The study examined the relationship of individual differences in prefrontal brain asymmetry, measured by the EEG in resting conditions, to the individual's responsivity in the context of humor (n=42). Several weeks after the EEG recording, immediate cardiovascular responses to the perception of humor and behavioral indicators of humor processing were obtained in an experimental paradigm involving non-verbal cartoons. Relatively greater resting activity in the left than right prefrontal cortex, particularly at the ventrolateral positions, was associated with faster detection of humor, a more pronounced cardiac response to the perception of humor (heart rate and cardiac output), and more accessible internal positive affective states (indicated by faster reports of amusement levels). The study confirms and extends findings of the relevance of prefrontal brain asymmetry to affective responsivity, contributing evidence in the domain of positive affect and humor, and demonstrating relationships to the immediate cardiovascular response pattern to an emotional event.

  20. Restoration of lost connectivity of partitioned wireless sensor networks

    Virender Ranga

    2016-05-01

    Full Text Available The lost connectivity due to failure of large scale nodes plays major role to degrade the system performance by generating unnecessary overhead or sometimes totally collapse the active network. There are many issues and challenges to restore the lost connectivity in an unattended scenario, i.e. how many recovery nodes will be sufficient and on which locations these recovery nodes have to be placed. A very few centralized and distributed approaches have been proposed till now. The centralized approaches are good for a scenario where information about the disjoint network, i.e. number of disjoint segments and their locations are well known in advance. However, for a scenario where such information is unknown due to the unattended harsh environment, a distributed approach is a better solution to restore the partitioned network. In this paper, we have proposed and implemented a semi-distributed approach called Relay node Placement using Fermat Point (RPFP. The proposed approach is capable of restoring lost connectivity with small number of recovery relay nodes and it works for any number of disjoint segments. The simulation experiment results show effectiveness of our approach as compared to existing benchmark approaches.

    This paper presents first experimental results for an IP telephony-based steganographic method called LACK (Lost Audio PaCKets steganography). This method utilizes the fact that in typical multimedia communication protocols like RTP (Real-Time Transport Protocol), excessively delayed packets are not used for the reconstruction of transmitted data at the receiver, i.e. these packets are considered useless and discarded. The results presented in this paper were obtained basing on a functional LACK prototype and show the method's impact on the quality of voice transmission. Achievable steganographic bandwidth for the different IP telephony codecs is also calculated.

Methods The study material included a database created on the basis of 5,219,205 death certificates of Polish inhabitants, gathered between 1999 and 2012 and provided by the Central Statistical Office. Crude Death Rates (CDR), Standardized Death Rates (SDR) and Standard Expected Years of Life Lost (SEYLL) due to infectious and parasitic diseases were also evaluated in the study period as well as Standard Expected Years of Life Lost per living person (SEYLLp) and Standard Expected Years of Life Lost per dead person (SEYLLd). Time trends were evaluated with the application of joinpoint models and an annual percentage change in their values. Results Death certificates report that 38,261 people died due to infectious diseases in Poland in the period 1999–2012, which made up 0.73% of the total number of deaths. SDR caused by these diseases decreased, particularly in the male group: Annual Percentage Change (APC = -1.05; 95% CI:-2.0 to -0.2; p<0.05). The most positive trends were observed in mortality caused by tuberculosis (A15-A19) (APC = -5.40; 95% CI:-6.3 to -4.5; p<0.05) and also meningitis, encephalitis, myelitis and encephalomyelitis (G03-G04) (APC = -3.42; 95% CI:-4.7 to -2.1; p<0.05). The most negative mortality trends were observed for intestinal infectious diseases (A00-A09) Annual Average Percentage Change (AAPC = 7.3; 95% CI:3.1 to 11.7; p<0.05). SDR substantially decreased in the first half of the study period, but then significantly increased in the second half. Infectious and parasitic diseases contributed to a loss of around 37,000 standard expected years of life in 1999 and more than 28,000 in 2012. During the study period, the SEYLLp index decreased from 9.59 to 7.39 per 10,000 population and the SEYLLd index decreased from 14.26 to 10.34 years (AAPC = 2.3; 95% CI:-2,9 to -1.7; p<0

    Every cancer-related death in someone of working age represents an economic loss to society. To inform priorities for cancer control, we estimated costs of lost productivity due to premature cancer-related mortality across Europe, for all cancers and by site, gender, region and country. Cancer deaths in 2008 were obtained from GLOBOCAN for 30 European countries across four regions. Costs were valued using the human capital approach. Years of productive life lost (YPLL) were computed by multiplying deaths between 15 and 64 years by working-life expectancy, then by country-, age- and gender-specific annual wages, corrected for workforce participation and unemployment. Lost productivity costs due to premature cancer-related mortality in Europe in 2008 were €75 billion. Male costs (€49 billion) were almost twice female costs (€26 billion). The most costly sites were lung (€17 billion; 23% of total costs), breast (€7 billion; 9%) and colorectum (€6 billion; 8%). Stomach cancer (in Southern and Central-Eastern Europe) and pancreatic cancer (in Northern and Western Europe) were also among the most costly sites. The average lost productivity cost per cancer death was €219,241. Melanoma had the highest cost per death (€312,798), followed by Hodgkin disease (€306,628) and brain and CNS cancer (€288,850). Premature mortality costs were 0.58% of 2008 European gross domestic product, highest in Central-Eastern Europe (0.81%) and lowest in Northern Europe (0.51%). Premature cancer-related mortality costs in Europe are significant. These results provide a novel perspective on the societal cancer burden and may be used to inform priority setting for cancer control.

  20. The lost sunspot cycle: New support from Be10 measurements

    CERN Document Server

    Karoff, C; Knudsen, M F; Olsen, J; Fogtmann-Schulz, A

    2014-01-01

    It has been suggested that the deficit in the number of spots on the surface of the Sun between 1790 and 1830, known as the Dalton minimum, contained an extra cycle that was not identified in the original sunspot record by Wolf. Though this cycle would be shorter and weaker than the average solar cycle, it would shift the magnetic parity of the solar magnetic field of the earlier cycles. This extra cycle is sometimes referred to as the 'lost solar cycle' or 'cycle 4b'. Here we reanalyse Be10 measurements with annual resolution from the NGRIP ice core in Greenland in order to investigate if the hypothesis regarding a lost sunspot cycle is supported by these measurements. Specifically, we make use of the fact that the Galactic cosmic rays, responsible for forming Be10 in the Earth's atmosphere, are affected differently by the open solar magnetic field during even and odd solar cycles. This fact enables us to evaluate if the numbering of cycles earlier than cycle 5 is correct. For the evaluation, we use Bayesian...

    2010-09-01

    In recent years, so-called 'lost crops' have been appraised in a number of reviews, among them Lablab purpureus in the context of African vegetable species. This crop cannot truly be considered 'lost' because worldwide more than 150 common names are applied to it. Based on a comprehensive literature review, this paper aims to put forward four theses, (i) Lablab is one of the most diverse domesticated legume species and has multiple uses. Although its largest agro-morphological diversity occurs in South Asia, its origin appears to be Africa. (ii) Crop improvement in South Asia is based on limited genetic diversity. (iii) The restricted research and development performed in Africa focuses either on improving forage or soil properties mostly through one popular cultivar, Rongai, while the available diversity of lablab in Africa might be under threat of genetic erosion. (iv) Lablab is better adapted to drought than common beans (Phaseolus vulgaris) or cowpea (Vigna unguiculata), both of which have been preferred to lablab in African agricultural production systems. Lablab might offer comparable opportunities for African agriculture in the view of global change. Its wide potential for adaptation throughout eastern and southern Africa is shown with a GIS (geographic information systems) approach.

    Full Text Available The paper discusses some aspects of ecology in the use of lost foam patterns for piece production of large castings poured from ferrousalloys under the conditions of Metalodlew SA. Foundry. The technological processes used in the manufacture of castings are related with numerous hazards. Numerous problems requiring prompt solution occur also during the process of foundry mould pouring, to mention only various contaminants, air pollution, noise and other factors harmful to the human health and natural environment. Varioustechnological processes cause strenuous work conditions in foundry shops. Many of the publications that have appeared so far dealing withthe problems of environmental protection and hard work conditions in foundries [1, 2, 3, 4, 5, 6, 7, 8, 9] discuss in both general anddetailed way problems related with various pollutants, noise and other factors harmful to the human health and natural environment,responsible for hazards faced by foundry workers. Studies carried out by various R&D centres are mainly focussed on the problem of howto reduce the harmful effect of technological processes on the environment through modification of the already existing or development of new ecological and energy-saving materials and technologies. This paper shows the opportunities and threats resulting from the application of the Lost Foam Process in a foundry, which up to now has been using a more traditional technology.

    2016-09-01

    Full Text Available Background: The aim of this study was to assess the economic burden of fire-related injury from two perspectives: post-injury social security compensations and also productivity losses due to the lost productive time from a societal perspective induced by the injury. Design and methods: A cohort of 1503 inpatients who sustained firerelated injury during the period 2001–2005 was retrospectively followed up for 5-10 years until the end of 2010, using linkages between several administrative registers. The study process was started in 2015 and finalized on March 2016. Results: Annual productivity loss was on average EUR 5.72 million, giving a total for the five-year study period of EUR 28.6 million, with a mean value of EUR 19,070 per person. Mean/median disability time for those who received benefits was 572/63 days, ranging from 3 days to 36.5 years. Total average cost of benefits to the injured annually during the study period was EUR 1.03 million. This equates to EUR 3430 per patient for the whole cohort or EUR 14,860 for those who received benefits. Conclusions: The burden of fire-related injuries in terms of payment transfers and lost productivity due to periods of disability as indirect costs is high; in a population of 5.4 million, the annual loss exceeded EUR 5.7 million. The results could be used in planning preventive measures and therefore yield savings

  10. Recovering lost 21 cm radial modes via cosmic tidal reconstruction

    CERN Document Server

    Zhu, Hong-Ming; Yu, Yu; Chen, Xuelei

    2016-01-01

    21 cm intensity mapping has emerged as a promising technique to map the large-scale structure of the Universe, at redshifts $z$ from 1 to 10. Unfortunately, many of the key cross correlations with photo-$z$ galaxies and the CMB have been thought to be impossible due to foreground contamination for radial modes with small wavenumbers. These modes are usually subtracted in the foreground subtraction process. We recover the lost 21 cm radial modes via cosmic tidal reconstruction and find more than 60\\% cross-correlation signal at $\\ell\\lesssim100$ and even more on larger scales can be recovered from null. The tidal reconstruction method opens up a new set of possibilities to probe our Universe and is extremely valuable not only for 21 cm surveys but also for CMB and photometric redshift observations.

  11. In search of lost insolence: Ferdydurke and cynicism

    Directory of Open Access Journals (Sweden)

    Jerzy Franczak

    2013-01-01

    Full Text Available This article is an attempt to interpret Witold Gombrowicz’s first novel in the context of cynicism, which is first conceptualized within the Foucauldian tradition as a practice of “frank speech” (parrhesia, and then, according to Peter Sloterdijk’s critical philosophy, as a form of modern consciousness based on inverted idealism. The opposition between an ancient subversive cynicism and its modern schizoid form allows one to analyze the complexity of Ferdydurke. In the course of interpretation it turns out that there are some intersecting planes: the protagonist searches in vain for lost insolence, but it is the author who manages to find it at the end of the novel.

  12. The lost-foam casting of aluminum alloy components

    Science.gov (United States)

    Shivkumar, S.; Wang, L.; Apelian, D.

    1990-11-01

    In the lost-foam casting process, liquid metal is poured directly onto a refractory-coated, foamed polymer pattern which is buried in loose sand. The polymer pattern undergoes thermal degradation and is gradually replaced by the molten metal, which solidifies and produces the casting. The inherent operating advantages of this innovative technique have generated considerable interest among casting manufacturers. Currently, the process is being utilized to manufacture a wide variety of ferrous and nonferrous components catering primarily to the automotive industry. Because the process is relatively new, there is a compelling need to quantify the influence of process parameters on microstructure and mechanical properties. Furthermore, the interaction of the thermal degradation products with the solidifying metal may produce several unique defects in the casting.

    The aim of this paper is to find lost siblings of the Sun by analyzing high resolution spectra. Finding solar siblings will enable us to constrain the parameters of the parental cluster and the birth place of the Sun in the Galaxy. The solar siblings can be identified by accurate measurements of metallicity, stellar age and elemental abundances for solar neighbourhood stars. The solar siblings candidates were kinematically selected based on their proper motions, parallaxes and colours. Stellar parameters were determined through a purely spectroscopic approach and partly physical method, respectively. Comparing synthetic with observed spectra, elemental abundances were computed based on the stellar parameters obtained using a partly physical method. A chemical tagging technique was used to identify the solar siblings. We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Ti, Cr, Fe, and Ni for 32 solar sibling candidates. Our abundances analysis shows that four ...

    Beckman, Richard Robert

    2001-10-01

    The LOST2 system is a new accurate underwater positioning system that nonlinearly combines parts of dead-reckoning, acoustic-based positioning, and terrain-based positioning. The system is composed of two major subsystems, a system observer and a constrained extended Kalman filter. Inputs to the system are as follows: (1)high resolution bathymetry, (2)measured ocean depth at the position of the vessel, (3)measured or estimated vessel velocity, (4)slant range to and position of a known point, and (5)an initial prediction of the vessel's location. The system development, simulation studies, results from sea trials and some suggestions for future work are presented. The system is capable of providing position estimates with the same degree of accuracy as present methods, with significantly less hardware. These results prove the concept of the system as a new method to position underwater vessels.

  20. The transcription factor REST is lost in aggressive breast cancer.

    Directory of Open Access Journals (Sweden)

    Matthew P Wagoner

    2010-06-01

    Full Text Available The function of the tumor suppressor RE1 silencing transcription factor (REST is lost in colon and small cell lung cancers and is known to induce anchorage-independent growth in human mammary epithelial cells. However, nothing is currently known about the role of this tumor suppressor in breast cancer. Here, we test the hypothesis that loss of REST function plays a role in breast cancer. To assay breast tumors for REST function, we developed a 24-gene signature composed of direct targets of the transcriptional repressor. Using the 24- gene signature, we identified a previously undefined RESTless breast tumor subtype. Using gene set enrichment analysis, we confirmed the aberrant expression of REST target genes in the REST-less tumors, including neuronal gene targets of REST that are normally not expressed outside the nervous system. Examination of REST mRNA identified a truncated splice variant of REST present in the REST-less tumor population, but not other tumors. Histological analysis of 182 outcome-associated breast tumor tissues also identified a subpopulation of tumors that lack full-length, functional REST and over-express the neuroendocrine marker and REST target gene Chromogranin A. Importantly, patients whose tumors were found to be REST-less using either the 24-gene signature or histology had significantly poorer prognosis and were more than twice as likely to undergo disease recurrence within the first 3 years after diagnosis. We show here that REST function is lost in breast cancer, at least in part via an alternative splicing mechanism. Patients with REST-less breast cancer undergo significantly more early disease recurrence than those with fully functional REST, regardless of estrogen receptor or HER2 status. Importantly, REST status may serve as a predictor of poor prognosis, helping to untangle the heterogeneity inherent in disease course and response to treatment. Additionally, the alternative splicing observed in REST

    In 1970, the Soviet Lunokhod 1 rover delivered a French-built laser reflector to the Moon. Although a few range measurements were made within three months of its landing, these measurements---and any that may have followed---are unpublished and unavailable. The Lunokhod 1 reflector was, therefore, effectively lost until March of 2010 when images from the Lunar Reconnaissance Orbiter (LRO) provided a positive identification of the rover and determined its coordinates with uncertainties of about 100 m. This allowed the Apache Point Observatory Lunar Laser-ranging Operation (APOLLO) to quickly acquire a laser signal. The reflector appears to be in excellent condition, delivering a signal roughly four times stronger than its twin reflector on the Lunokhod 2 rover. The Lunokhod 1 reflector is especially valuable for science because it is closer to the Moon's limb than any of the other reflectors and, unlike the Lunokhod 2 reflector, we find that it is usable during the lunar day. We report the selenographic positi...

  12. Identifying the lost generation of adults with autism spectrum conditions.

    Lai, Meng-Chuan; Baron-Cohen, Simon

    2015-11-01

    Autism spectrum conditions comprise a set of early-onset neurodevelopmental syndromes with a prevalence of 1% across all ages. First diagnosis in adulthood has finally become recognised as an important clinical issue due to the increasing awareness of autism, broadening of diagnostic criteria, and the introduction of the spectrum concept. Thus, the idea of a lost generation of people who were previously excluded from a diagnosis of classic autism has arisen. Making a first diagnosis of autism spectrum conditions in adults can be challenging for practical reasons (eg, no person to provide a developmental history), developmental reasons (eg, the acquisition of learnt or camouflaging strategies), and clinical reasons (eg, high frequency of co-occurring disorders). The diagnostic process includes referral, screening, interviews with informants and patients, and functional assessments. In delineating differential diagnoses, true comorbidities, and overlapping behaviour with other psychiatric diagnoses, particular attention should be paid to anxiety, depression, obsessive-compulsive disorder, psychosis, personality disorders, and other neurodevelopmental disorders. Possible misdiagnosis, especially in women, should be explored. The creation of supportive, accepting, and autism-friendly social and physical environments is important and requires a coordinated effort across agencies and needs support from government policies.

  13. [The lost decade of global polio eradication and moving forward].

    2010-06-01

    The Global Polio Eradication Initiative was aimed to eradicate poliomyelitis by the year 2000, however, polio eradication is still not in sight even in 2010, over 10 years after the initial target date. In 2010, indigenous transmission of wild polioviruses has been interrupted throughout the world except four countries, Afghanistan, Pakistan, India, and Nigeria. Despite the intense use of monovalent oral polio vaccines, type 1 and type 3 wild polioviruses still circulate in the four remaining polio-endemic countries, and multiple importations of wild polioviruses have also occurred extensively from Nigeria and India to a number of previously polio-free countries in Africa, Asia, and Europe. Furthermore, the emergence of type 2 vaccine-derived polioviruses has raised concerns about low level of immunity against type 2 poliovirus in some polio-endemic areas like Nigeria and India. On the other hand, operational improvements in 2009 were reported in high-risk states in northern Nigeria and transmission of type 1 and type 3 polioviruses in Nigeria is markedly declining from 2009 to 2010. Moreover, bivalent oral polio vaccine containing Sabin 1 and Sabin 3 strains has been introduced in 2010 as a promising tool to improve and simplify the supplemental immunization activities in high-risk areas. Although there was no apparent decline in the annual number of polio cases in 2000-2009 globally, it would be critical to review our experience during "the lost decade of global polio eradication" to move forward into the final stage of global polio eradication.

    Studies concerning marine litter have received great attention over the last several years by the scientific community mainly due to their ecological and economic impacts in marine ecosystems, from coastal waters to the deep ocean seafloor. The distribution, type and abundance of marine litter in Ormonde and Gettysburg, the two seamounts of Gorringe Bank, were analyzed from photo and video imagery obtained during ROV-based surveys carried out at 60-3015 m depths during the E/V Nautilus cruise NA017. Located approximately 125 nm southwest of Portugal, Gorringe Bank lays at the crossroad between the Atlantic and the Mediterranean and is therefore characterized by an intense maritime traffic and fishing activities. The high frequency of lost or discarded fishing gear, such as cables, longlines and nets, observed on Gorringe Bank suggests an origin mostly from fishing activities, with a clear turnover in the type of litter (mostly metal, glass and to a much lesser extent, plastic) with increasing depth. Litter was more abundant at the summit of Gorringe Bank (ca. 4 items·km- 1), decreasing to less than 1 item·km- 1 at the flanks and to ca. 2 items·km- 1 at greater depths. Nevertheless, litter abundance appeared to be lower than in continental margin areas. The results presented herein are a contribution to support further actions for the conservation of vulnerable habitats on Gorringe Bank so that they can continue contributing to fishery productivity in the surrounding region.

    We show that partial recovery of the entanglement lost in a bipartite pure state entanglement transformations is almost always possible irrespective of the dimension. Let $\\ket{\\psi}$ and $\\ket{\\vph}$ be $n\\times n$ states and $\\ket{\\psi} \\longrightarrow \\ket{\\vph}$ under local operations. We ask whether there exists $k\\times k$ states, $\\ket{\\chi}$ and $\\ket{\\omega}$, $k E(\\ket{\\chi})$, $E$ being the entropy of entanglement such that $\\ket{\\psi}\\otimes\\ket{\\chi} \\longrightarrow \\ket{\\vph}\\otimes\\ket{\\omega}$ under LOCC. We show that for almost all pairs of comparable states recovery is achievable by $2\\times 2$ states, no matter how large the dimension of the parent states are. For other cases we show that the dimension of the auxiliary entangled state depends on the presence of equalities in the majorization relations of the parent states. We identify those states and show that recovery is still possible using states in $k\\times k$, $2

    CERN Multimedia

    2008-01-01

    Martha Jones, ex-time traveller and now working as a doctor for a UN task force, has been called to CERN where they're about to activate the Large Hadron Collider. Once activated, the Collider will fire beams of protons together recreating conditions a billionth of a second after the Big Bang - and potentially allowing the human race a greater insight into what the Universe is made of. But so much could go wrong - it could open a gateway to a parallel dimension, or create a black hole - and now voices from the past are calling out to people and scientists have started to disappear... Where have the missing scientists gone? What is the secret of the glowing man? What is lurking in the underground tunnel? And do the dead ever really stay dead? Lost Souls is a spin-off from the award-winning BBC Wales TV production Torchwood. It stars John Barrowman, Freema Agyeman, Eve Myles, Gareth David-Lloyd, Lucy Montgomery (of Titty Bang Bang) and Stephen Critchlow.

  17. Effect of Foamed Pattern Density on the Lost Foam Process

    2007-07-01

    Full Text Available The study examines the effect of the foamed polystyrene pattern density on the process of making castings by the lost foam technique with emphasis put on the analysis of simulation tests. The simulation regarded the effect that pattern density is said to have on the mould cavity filling rate, pressure in the gas gap, and size of this gap. For simulation tests of the full mould process, a mathematical model presented in this study was used. For calculations, the author's own algorithm was applied. The investigations have proved that with decreasing pattern density the pouring rate increases, while pressure in the gas gap and the size of the gap are decreasing. The increasing pouring rate ensures correct making of castings, even if their shapes are very intricate and the wall cross-sections are very small. Smaller size of the gas gap and lower pressure of gases in this gap reduce the risk of mould damage. The author’s own investigations have proved a very significant effect of the density of foamed polystyrene pattern on the casting process, and specially on the mould pouring rate. The best pouring rate is ensured by patterns of the density comprised in a range of ρ2 =18÷25 kg/m3.

    1999-05-01

    Research accounts of the struggle of professions to attain and maintain a monopoly, strategies of exclusion and usurpation, make for interesting and often exciting reading. The purpose of this article is to present a less frequently reported phenomenon--the study of a profession that had a monopoly, and then lost it. The authors attempt to answer the question: under what circumstances will a profession support the state in breaking their own monopoly? The study looked at the pharmacy profession in Iceland in the light of the recent change in drug legislation. Interviews with key actors in the pharmacy profession were conducted to gain an understanding of how they interpreted and experienced this change. Three factors contributed to the break in the professional monopoly: (1) political desire to take advantage of new competition and deregulation policy, (2) desire to cut the health budget and (3) internal divisions within the profession. The results of the study revealed at least four internal divisions within the pharmacy profession: (1) urban/rural, (2) employer/employee, (3) lower/higher education and (4) young/old. The article illustrates how a profession weakened by internal strife became prey to the government's cost cutting activities. This study is an example of how internal conflicts not only weakened the profession, but created a climate conducive to losing its monopoly. Our findings raise fundamental questions about the future of professions in society today.

    Full Text Available Microstructure and mechanical properties of lost foam cast aluminum alloys have been investigated in both primary A356 (0.13% Fe and secondary 356 (0.47%. As expected, secondary 356 shows much higher content of Fe-rich intermetallic phases, and in particular the porosity in comparison with primary A356. The average area percent and size (length of Fe-rich intermetallics change from about 0.5% and 6 祄 in A356 to 2% and 25 祄 in 356 alloy. The average area percent and maximum size of porosity also increase from about 0.4% and 420 祄 to 1.4% and 600 祄, respectively. As a result, tensile ductility decreases about 60% and ultimate tensile strength declines about 8%. Lower fatigue strength was also experienced in the secondary 356 alloy. Low cycle fatigue (LCF strength decreased from 187 MPa in A356 to 159 MPa in 356 and high cycle fatigue (HCF strength also declined slightly from 68 MPa to 64 MPa.

    2004-03-01

    The peculiar biogeography of the so-called "Lost World", i.e. the summits of sandstone tableaux ( tepuis) in the Neotropical Guyana region of Venezuela, has generated a debate regarding the factors that are thought to account for modern vegetation patterns in the region. Some argue that plant communities on these high-elevation summits reflect a long history of evolution in isolation, while others surmise that there has been substantial biotic interchange with the surrounding lowlands during glacial times. Until now, these apparently competing hypotheses have not been tested using palaeoecological methods. I used pollen analysis of Quaternary sediments and documented past vertical migrations of vegetation in response to climate changes, which supports the second hypothesis. Physiographical analysis, however, shows that about half the tableaux summits are too high for their flora to have reached the lowlands during the last glaciation, suggesting that a portion of the tableaux vegetation has always experienced some degree of biotic isolation. Thus, a component of the summit vegetation evolved in isolation, whereas other taxa experienced interchange, as reflected in endemism patterns among the tableaux summits. Biogeographical patterns on the summits are the result of complex evolutionary processes. The two hypotheses invoked to explain the vegetation patterns are not mutually exclusive, but instead complement one another.

  7. Space Radar Image of the Lost City of Ubar

    Science.gov (United States)

    1999-01-01

    This is a radar image of the region around the site of the lost city of Ubar in southern Oman, on the Arabian Peninsula. The ancient city was discovered in 1992 with the aid of remote sensing data. Archeologists believe Ubar existed from about 2800 B.C. to about 300 A.D. and was a remote desert outpost where caravans were assembled for the transport of frankincense across the desert. This image was acquired on orbit 65 of space shuttle Endeavour on April 13, 1994 by the Spaceborne Imaging Radar C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR). The SIR-C image shown is centered at 18.4 degrees north latitude and 53.6 degrees east longitude. The image covers an area about 50 by 100 kilometers (31 miles by 62 miles). The image is constructed from three of the available SIR-C channels and displays L-band, HH (horizontal transmit and receive) data as red, C-band HH as blue, and L-band HV (horizontal transmit, vertical receive) as green. The prominent magenta colored area is a region of large sand dunes, which are bright reflectors at both L-and C-band. The prominent green areas (L-HV) are rough limestone rocks, which form a rocky desert floor. A major wadi, or dry stream bed, runs across the middle of the image and is shown largely in white due to strong radar scattering in all channels displayed (L and C HH, L-HV). The actual site of the fortress of the lost city of Ubar, currently under excavation, is near the Wadi close to the center of the image. The fortress is too small to be detected in this image. However, tracks leading to the site, and surrounding tracks, appear as prominent, but diffuse, reddish streaks. These tracks have been used in modern times, but field investigations show many of these tracks were in use in ancient times as well. Mapping of these tracks on regional remote sensing images was a key to recognizing the site as Ubar in 1992. This image, and ongoing field investigations, will help shed light on a little known early civilization. Spaceborne

    Approximately 50 % of all acromegalic patients will require lifelong medical treatment to normalize mortality rates and reduce morbidity. Thus, adherence to therapy is essential to achieve treatment goals. To date, no study has evaluated the frequency and reasons for loss to follow-up in the acromegalic population. The current study aimed at evaluating the frequency of acromegalic patient loss to follow-up in three reference centers and the reasons responsible for their low compliance with treatment. All of the files for the acromegalic patients in the three centers were reviewed. Those patients, who had not followed up with the hospital for more than a year, were contacted via phone and/or mail and invited to participate. Patients who agreed to participate were interviewed, and blood samples were collected. A total of 239 files were reviewed; from these 42 patients (17.6 %) were identified who were lost to follow-up. It was possible to contact 27 of these patients, 10 of whom did not attend the appointments for more than one time and 17 of whom agreed to participate in the study. Fifteen of these 17 patients had active disease (88.2 %), and all of the patients restarted treatment in the original centers. The main reason for loss to follow-up was an absence of symptoms. High-quality follow-up is important in acromegaly to successfully achieve the aims of the treatment. An active search for patients may allow the resumption of treatment in a significant proportion of these cases, contributing to reduced morbidity and mortality in this patient population.

    A systematic study of Kodak’s annual operations and business strategies during 2000-2010revealed that Kodak management faltered in transitioning the Kodak Company from an analog business model to a digital business model.In 2000 Kodak delivered strong performance and it appeared to be smart to be in the picture business.In 2002Kodak was the best-performing stock among companies that made up the Dow Jones Industrial Average.In 2005Kodak future looked bright.A confident Chairman and CEO Antonio M.Perez pronounced that by 2008he expected all of Kodak’s businesses to be leaders in their industry segments.In 2008Kodak remained as the most recognized and respected brands in the world but it played in the hyper competitive markets in which price and technological advances drove the market.So Kodak was unable to reap premium prices from its famous brand and it became a nonviable business due to sustained losses from continuing operations.During 2008-2012 Kodak fell from being a market leader to becoming a bankrupt Company.Using the analogy of"behind the power curve",this article shines light on Kodak’s crash to the ground,i.e.bankruptcy filing in 2012and asserts that Kodak management triggered the process of falling behind the power curve in 2000when it embraced the infoimaging strategy to extend the benefits of film.Kodak’s 2003digital business model and other strategies that followed it did not allow Kodak to become a strong competitor in the digital world.Kodak digital camera business became a lost business opportunity.

  10. Monitoring metal-fill in a lost foam casting process.

    The lost foam casting (LFC) process is emerging as a reliable casting method. The metal-fill profile in LFC plays an important role among several factors that affect casting quality. The metal-fill profile is in turn affected by several factors. Several casting defects may result due to an improper metal-fill process. Hence, it becomes essential to characterize and control, if possible, the metal-fill process in LFC. This research presents instrumentation and a technique to monitor and characterize the metal-fill process. The characterization included the determination of the position of the metal front and the profile in which the metal fills up the foam pattern. The instrumentation included capacitive sensors. Each sensor is comprised of two electrodes whose capacitive coupling changes as the metal fills the foam pattern. Foundry tests were conducted to obtain the sensors' responses to the metal fill. Two such sensors were used in the foundry tests. Data representing the responses of these sensors during the metal-fill process were collected using a data acquisition system. A number of finite element electrostatic simulations were carried out to study the metal-fill process under conditions similar to those experienced in foundry tests. An artificial neural network was trained using the simulation data as inputs and the corresponding metal-fill profiles as outputs. The neural network was then used to infer the profile of the metal-fill during foundry tests. The results were verified by comparing the metal-fill profile inferred from the neural network to the actual metal-fill profile captured by an infrared camera used during the foundry tests. The match up between the inferred profiles and the infrared camera measurements was satisfactory, indicating that the developed technique provides a reliable and cost effective method to monitor the metal-fill profile in LFC.

    2007-01-01

    Interest in development of brain prostheses, which might be proposed to recover mental functions lost due to neuron-degenerative disease or trauma, requires new methods in molecular engineering and nanotechnology to build artificial brain tissues. We develop a Dynamic Core model to analyze complexity of damaged biological neural network as well as transition and recovery of the system functionality due to changes in the system environment. We provide a method to model complexity of physical systems which might be proposed as an artificial tissue or prosthesis. Delocalization of Dynamic Core model is developed to analyze migration of mental functions in dynamic bio-systems which undergo architecture transition induced by trauma. Term Dynamic Core is used to define a set of causally related functions and Delocalization is used to describe the process of migration. Information geometry and topological formalisms are proposed to analyze information processes. A holographic model is proposed to construct dynamic e...

    Aims: The aim of this paper is to find lost siblings of the Sun by analyzing high resolution spectra. Finding solar siblings will enable us to constrain the parameters of the parental cluster and the birth place of the Sun in the Galaxy. Methods: The solar siblings can be identified by accurate measurements of metallicity, stellar age and elemental abundances for solar neighbourhood stars. The solar siblings candidates were kinematically selected based on their proper motions, parallaxes and colours. Stellar parameters were determined through a purely spectroscopic approach and partly physical method, respectively. Comparing synthetic with observed spectra, elemental abundances were computed based on the stellar parameters obtained using a partly physical method. A chemical tagging technique was used to identify the solar siblings. Results: We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Ti, Cr, Fe, and Ni for 32 solar sibling candidates. Our abundances analysis shows that four stars are chemically homogenous together with the Sun. Technique of chemical tagging gives us a high probability that they might be from the same open cluster. Only one candidate - HIP 40317 - which has solar metallicity and age could be a solar sibling. We performed simulations of the Sun's birth cluster in analytical Galactic model and found that most of the radial velocities of the solar siblings lie in the range -10 ≤ Vr ≤ 10 km s-1, which is smaller than the radial velocity of HIP 40317 (Vr = 34.2 km s-1), under different Galactic parameters and different initial conditions of the Sun's birth cluster. The sibling status for HIP 40317 is not directly supported by our dynamical analysis. Based on observations made with Nordic Optical Telescope at La Palma under programme 44-014.

    With the increased emphasis on vehicle weight reduction, production of near-net shape components by lost foam casting will make significant inroad into the next-generation of engineering component designs. The lost foam casting process is a cost effective method for producing complex castings using an expandable polystyrene pattern and un-bonded sand. The use of un-bonded molding media in the lost foam process will impose less constraint on the solidifying casting, making hot tearing less prevalent. This is especially true in Al-Mg and Al-Cu alloy systems that are prone to hot tearing when poured in rigid molds partially due to their long freezing range. Some of the unique advantages of using the lost foam casting process are closer dimensional tolerance, higher casting yield, and the elimination of sand cores and binders. Most of the aluminum alloys poured using the lost foam process are based on the Al-Si system. Very limited research work has been performed with Al-Mg and Al-Cu type alloys. With the increased emphasis on vehicle weight reduction, and given the high-strength-to-weight-ratio of magnesium, significant weight savings can be achieved by casting thin-wall (≤ 3 mm) engineering components from both aluminum- and magnesium-base alloys.

    Full Text Available Abstract Background Incomplete ascertainment of outcomes in randomized controlled trials (RCTs is likely to bias final study results if reasons for unavailability of patient data are associated with the outcome of interest. The primary objective of this study is to assess the potential impact of loss to follow-up on the estimates of treatment effect. The secondary objectives are to describe, for published RCTs, (1 the reporting of loss to follow-up information, (2 the analytic methods used for handling loss to follow-up information, and (3 the extent of reported loss to follow-up. Methods We will conduct a systematic review of reports of RCTs recently published in five top general medical journals. Eligible RCTs will demonstrate statistically significant effect estimates with respect to primary outcomes that are patient-important and expressed as binary data. Teams of 2 reviewers will independently determine eligibility and extract relevant information from each eligible trial using standardized, pre-piloted forms. To assess the potential impact of loss to follow-up on the estimates of treatment effect we will, for varying assumptions about the outcomes of participants lost to follow-up (LTFU, calculate (1 the percentage of RCTs that lose statistical significance and (2 the mean change in effect estimate across RCTs. The different assumptions we will test are the following: (1 none of the LTFU participants had the event; (2 all LTFU participants had the event; (3 all LTFU participants in the treatment group had the event; none of those in the control group had it (worst case scenario; (4 the event incidence among LTFU participants (relative to observed participants increased, with a higher relative increase in the intervention group; and (5 the event incidence among LTFU participants (relative to observed participants increased in the intervention group and decreased in the control group. Discussion We aim to make our objectives and methods

    Objectives To project the number of people aged 45–64 years with lost productive life years (PLYs) due to diabetes and related costs (lost income, extra welfare payments, lost taxation revenue); and lost gross domestic product (GDP) attributable to diabetes in Australia from 2015 to 2030. Design A simulation study of how the number of people aged 45–64 years with diabetes increases over time (based on population growth and disease trend data) and the economic losses incurred by individuals and the government. Cross-sectional outputs of a microsimulation model (Health&WealthMOD2030) which used the Australian Bureau of Statistics’ Survey of Disability, Ageing and Carers 2003 and 2009 as a base population and integrated outputs from two microsimulation models (Static Incomes Model and Australian Population and Policy Simulation Model), Treasury's population and labour force projections, and chronic disease trends data. Setting Australian population aged 45–64 years in 2015, 2020, 2025 and 2030. Outcome measures Lost PLYs, lost income, extra welfare payments, lost taxation revenue, lost GDP. Results 18 100 people are out of the labour force due to diabetes in 2015, increasing to 21 400 in 2030 (18% increase). National costs consisted of a loss of $A467 million in annual income in 2015, increasing to $A807 million in 2030 (73% increase). For the government, extra annual welfare payments increased from $A311 million in 2015 to $A350 million in 2030 (13% increase); and lost annual taxation revenue increased from $A102 million in 2015 to $A166 million in 2030 (63% increase). A loss of $A2.1 billion in GDP was projected for 2015, increasing to $A2.9 billion in 2030 attributable to diabetes through its impact on PLYs. Conclusions Individuals incur significant costs of diabetes through lost PLYs and lost income in addition to disease burden through human suffering and healthcare costs. The government incurs extra welfare payments, lost taxation revenue and

    Peroxisomes are essential organelles in higher eukaryotes as they play a major role in numerous metabolic pathways and redox homeostasis. Some peroxisomal abnormalities, which are often not compatible with life or normal development, were identified in severe demyelinating and neurodegenerative brain diseases. The metabolic roles of peroxisomes, especially in the brain, are described and human brain peroxisomal disorders resulting from a peroxisome biogenesis or a single peroxisomal enzyme defect are listed. The brain abnormalities encountered in these disorders (demyelination, oxidative stress, inflammation, cell death, neuronal migration, differentiation) are described and their pathogenesis are discussed. Finally, the contribution of peroxisomal dysfunctions to the alterations of brain functions during aging and to the development of Alzheimer's disease is considered.

  8. Density and Mechanical Properties of Aluminum Lost Foam Casting by Pressurization during Solidification

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Porosity is thought to be severe in aluminum alloy castings produced by lost foam process due to the pyrolysis of the polystyrene foam pattern during pouring, which results in detrimental effect in mechanical property.The slow solidification rate promotes the formation of gassing pin holes, and relative weakness of the thermal gradients can cause micro-shrinkage if the outline of the part complicates feeding in the lost foam casting. One of the methods to eliminate the porosity is to apply high pressure to the molten metal like an isostatic forging during solidification. Fundamental experiments were carried out to evaluate the effect of the external pressure on the porosity and mechanical properties of A356.2 alloy bar in the lost foam casting. Solidification time and porosity decreased with increasing the applied pressure during solidification. Applying external pressure was effective in decreasing the porosity and increasing the elongation of the lost foam casting.

    2013-01-01

    The diagnosis of brain death should be based on a simple premise. If every possible confounder has been excluded and all possible treatments have been tried or considered, irreversible loss of brain function is clinically recognized as the absence of brainstem reflexes, verified apnea, loss of vascular tone, invariant heart rate, and, eventually, cardiac standstill. This condition cannot be reversed - not even partly - by medical or surgical intervention, and thus is final. Many countries in the world have introduced laws that acknowledge that a patient can be declared brain-dead by neurologic standards. The U.S. law differs substantially from all other brain death legislation in the world because the U.S. law does not spell out details of the neurologic examination. Evidence-based practice guidelines serve as a standard. In this chapter, I discuss the history of development of the criteria, the current clinical examination, and some of the ethical and legal issues that have emerged. Generally, the concept of brain death has been accepted by all major religions. But patients' families may have different ideas and are mostly influenced by cultural attitudes, traditional customs, and personal beliefs. Suggestions are offered to support these families.

    Hoefflinger, Bernd

    Beyond the digital neural networks of Chap. 16, the more radical mapping of brain-like structures and processes into VLSI substrates has been pioneered by Carver Mead more than 30 years ago [1]. The basic idea was to exploit the massive parallelism of such circuits and to create low-power and fault-tolerant information-processing systems. Neuromorphic engineering has recently seen a revival with the availability of deep-submicron CMOS technology, which allows for the construction of very-large-scale mixed-signal systems combining local analog processing in neuronal cells with binary signalling via action potentials. Modern implementations are able to reach the complexity-scale of large functional units of the human brain, and they feature the ability to learn by plasticity mechanisms found in neuroscience. Combined with high-performance programmable logic and elaborate software tools, such systems are currently evolving into user-configurable non-von-Neumann computing systems, which can be used to implement and test novel computational paradigms. The chapter introduces basic properties of biological brains with up to 200 Billion neurons and their 1014 synapses, where action on a synapse takes ˜10 ms and involves an energy of ˜10 fJ. We outline 10x programs on neuromorphic electronic systems in Europe and the USA, which are intended to integrate 108 neurons and 1012 synapses, the level of a cat's brain, in a volume of 1 L and with a power dissipation design an intelligent technical response.

    Full Text Available This paper deals with the problem of optimal control for the transmission dynamics of tuberculosis (TB. A TB model that considers the existence of a new class (mainly in the African context is considered: the lost to follow up individuals. Based on the model formulated and studied in the work of Plaire Tchinda Mouofo, (2009, the TB control is formulated and solved as an optimal control theory problem using the Pontryagin's maximum principle (Pontryagin et al., 1992. This control strategy indicates how the control of the lost to follow up class can considerably influence the basic reproduction ratio so as to reduce the number of lost to follow up. Numerical results show the performance of the optimization strategy.

    Lost Circulation is a widespread problem encountered when drilling geothermal wells, and often represents a substantial portion of the cost of drilling a well. The U.S. Department of Energy sponsors research and development work at Sandia National Laboratories in an effort to reduce these lost circulation expenditures. Sandia has developed a down hole tool that improves the effectiveness and reduces th cost of lost circulation cement treatment while drilling geothermal wells. This tool, the Drillable Straddle Packer, is a low-cost disposable device that is used to isolate the loss zone and emplace the cement treatment directly into the region of concern. This report documents the design and development of the Drillabe Straddle Packer, the laboratory and field test results, and the design package that is available to transfer this technology to industry users.

    This report summarizes the results and the assumptions used in an analysis of the potential “lost efficiency opportunities” in the buildings sector. These targets of opportunity are those end-uses, applications, practices, and portions of the buildings market which are not currently being addressed, or addressed fully, by the Building Technologies Program (BTP) due to lack of resources. The lost opportunities, while a significant increase in effort and impact in the buildings sector, still represent only a small portion of the full technical potential for energy efficiency in buildings.

    In order to create a novel model of memory and brain function, we focus our approach on the sub-molecular (electron), molecular (tubulin) and macromolecular (microtubule) components of the neural cytoskeleton. Due to their size and geometry, these systems may be approached using the principles of quantum physics. We identify quantum-physics derived mechanisms conceivably underlying the integrated yet differentiated aspects of memory encoding/recall as well as the molecular basis of the engram. We treat the tubulin molecule as the fundamental computation unit (qubit) in a quantum-computational network that consists of microtubules (MTs), networks of MTs and ultimately entire neurons and neural networks. We derive experimentally testable predictions of our quantum brain hypothesis and perform experiments on these.

    A recent paper famously accused the rising field of social neuroscience of using faulty statistics under the catchy title ‘Voodoo Correlations in Social Neuroscience’. This Special Issue invites us to take this claim as the starting point for a cross-cultural analysis: in which meaningful ways can recent research in the burgeoning field of functional imaging be described as, contrasted with, or simply compared to animistic practices? And what light does such a reading shed on the dynamics and effectiveness of a century of brain research into higher mental functions? Reviewing the heated debate from 2009 around recent trends in neuroimaging as a possible candidate for current instances of ‘soul catching’, the paper will then compare these forms of primarily image-based brain research with older regimes, revolving around the deciphering of the brain’s electrical activity. How has the move from a decoding paradigm to a representational regime affected the conceptualisation of self, psyche, mind and soul (if there still is such an entity)? And in what ways does modern technoscience provide new tools for animating brains? PMID:27292322

  7. The orphaning experience: descriptions from Ugandan youth who have lost parents to HIV/AIDS

    Full Text Available Abstract The HIV/AIDS epidemic has continued to pose significant challenges to countries in Sub-Saharan Africa. Millions of African children and youth have lost parents to HIV/AIDS leaving a generation of orphans to be cared for within extended family systems and communities. The experiences of youth who have lost parents to the HIV/AIDS epidemic provide an important ingress into this complex, evolving, multi-dimensional phenomenon. A fundamental qualitative descriptive study was conducted to develop a culturally relevant and comprehensive description of the experiences of orphanhood from the perspectives of Ugandan youth. A purposeful sample of 13 youth who had lost one or both parents to HIV/AIDS and who were affiliated with a non-governmental organization providing support to orphans were interviewed. Youth orphaned by HIV/AIDS described the experience of orphanhood beginning with parental illness, not death. Several losses were associated with the death of a parent including lost social capitol, educational opportunities and monetary assets. Unique findings revealed that youth experienced culturally specific stigma and conflict which was distinctly related to their HIV/AIDS orphan status. Exploitation within extended cultural family systems was also reported. Results from this study suggest that there is a pressing need to identify and provide culturally appropriate services for these Ugandan youth prior to and after the loss of a parent(s.

  14. Quantitative evaluation of wall heat loads by lost fast ions in the Large Helical Device

    Science.gov (United States)

    Morimoto, Junki; Suzuki, Yasuhiro; Seki, Ryosuke

    2016-10-01

    In fusion plasmas, fast ions are produced by neutral beam injections (NBI), ion cyclotron heating (ICH) and fusion reactions. Some of fast ions are lost from fusion plasmas because of some kinds of drift and instability. These lost fast ions may cause damages on plasma facing components such as divertors and diagnostic instruments in fusion reactors. Therefore, wall heat loads by lost fast ions in the Large Helical Device (LHD) is under investigation. For this purpose, we have been developing the Monte-Carlo code for the quantitative evaluation of wall heat loads based on following the guiding center orbits of fast ions. Using this code, we investigate wall heat loads and hitting points of lost fast ions produced by NBI in LHD. Magnetic field configurations, which depend on beta values, affect orbits of fast ions and wall heat loads. Therefore, the wall heat loads by fast ions in equilibrium magnetic fields including finite beta effect and magnetic islands are quantitatively evaluated. The differences of wall heat loads and particle deposition patterns for cases of the vacuum field and various beta equilibrium fields will be presented at the meeting.

    Full Text Available Background: The aesthetic has an important role in social life, especially the anterior teeth. The aesthetic abnormality of anterior teeth i.e. discoloration, malpotition or the anterior teeth with crown damage for more than one third or all part of crown is lost due to caries or other causes, will influence its appearance especially during smile. Purpose: The aim of this case report, therefore, is to show how teeth with clinical crown lost or only the root left still can be treated by endorestoration treatment in order to reconstruct the shape and function of the teeth similar to the original ones. Case: Female 52 years old with the lost crown of anterior teeth. The patient did not want her teeth to be extracted. Case Management: The abnormality of these teeth are still able to be reconstructed by endorestoration i.e. endodontic treatment with post and core insertion in the root canal will increase its retention and recovery by the porcelain crown fused to metal to recover the original formation and aesthetic and thus has the normal refunction. The treatment, it improve the confidence of the patient, and also can function normally. The patient did not feel pain. Ronsenography showed the periapical lesion diminished, the neighbor gingival was going better in both function and color. Conclusion: Endorestoration treatment on the anterior teeth with lost crown could recover the normal function, dental aesthetic and self confidence.

  18. Effect of Process Parameters on Porosity in Aluminum Lost Foam Process

    Institute of Scientific and Technical Information of China (English)

    Kiyoung KIM; Kyongwhoan LEE

    2005-01-01

    Porosity is a main defect in aluminum alloy castings, which is also thought to be severe in aluminum alloy castings produced by lost foam process due to the pyrolysis of the polystyrene foam pattern during pouring. Fundamental experiments were carried out to evaluate the effect of process parameters such as the melt treatment, the cooling rate and the density of expanded polystyrene (EPS) foam on porosity in A356.2 bar casting. The effect of melt treatment including degassing and refining was investigated. The effect of cooling rate was also evaluated by changing the mold packing material such as the silica sand, the zircon sand and the steel shots. Gas entrapment due to the turbulent metal flow during mold filling in conventional molding process results in porosity. Mold filling sequence in lost foam process is different from that in conventional molding process. The effect of molten metal flow was estimated by comparing the density of the casting by conventional sodium silicate molding with that by lost foam process. Density measurement was conducted to analyze the extent of porosity in the casting. Source of the porosity in lost foam process can be divided into two factors, i.e. turbulence in molten metal flow and entraining residue or gas from the pattern during pouring.

  6. Years of life lost due to external causes of death in the lodz province, poland.

    Directory of Open Access Journals (Sweden)

    Malgorzata Pikala

    Full Text Available BACKGROUND: The aim of the study is the analysis of years of life lost due to external causes of death, particularly due to traffic accidents and suicides. MATERIALS AND METHODS: The study material includes a database containing information gathered from 376,281 death certificates of inhabitants of the Lodz province who died between 1999 and 2010. The Lodz province is characterized by the highest mortality rates in Poland. The SEYLLp (Standard Expected Years of Life Lost per living person and the SEYLLd (per death indices were used to determine years of life lost. Joinpoint models were used to analyze time trends. RESULTS: In 2010, deaths due to external causes constituted 6.0% of the total number of deaths. The standardized death rate (SDR due to external causes was 110.0 per 100,000 males and was five times higher than for females (22.0 per 100,000 females. In 2010, the SEYLLp due to external causes was 3746 per 100,000 males and 721 per 100,000 females. Among males, suicides and traffic accidents were the most common causes of death (the values of the SEYLLp were: 1098 years and 887 years per 100,000 people, respectively. Among females, the SEYLLp values were 183 years due to traffic accidents and 143 years due to suicides (per 100,000 people. CONCLUSIONS: A decrease in the number of years of life lost due to external causes is much higher among females. The authors observe that a growing number of suicides contribute to an increase in the value of the SEYLLp index. This directly contributes to over-mortality of males due to external causes. The analysis of the years of life lost focuses on the social and economic aspects of premature mortality due to external causes.

    2002-12-01

    A field study using 621 "lost" letters was conducted in the city of Mobile and in small towns in mostly rural Baldwin County, Alabama. Milgram's lost letter technique was validated against the actual votes cast during the November 7, 2000 General Election. The technique was successful as an unobtrusive measure useful for predicting patterns of voting behavior. Rates of return of lost letters "in favor of and opposed to legalizing interracial marriage" agreed with the actual election returns (chi-square "goodness of fit"). Community size seemed associated with return of lost letters.

    2014-10-03

    Aging-associated cognitive decline is affected by factors produced inside and outside the brain. By using multiorgan genome-wide analysis of aged mice, we found that the choroid plexus, an interface between the brain and the circulation, shows a type I interferon (IFN-I)-dependent gene expression profile that was also found in aged human brains. In aged mice, this response was induced by brain-derived signals, present in the cerebrospinal fluid. Blocking IFN-I signaling within the aged brain partially restored cognitive function and hippocampal neurogenesis and reestablished IFN-II-dependent choroid plexus activity, which is lost in aging. Our data identify a chronic aging-induced IFN-I signature, often associated with antiviral response, at the brain's choroid plexus and demonstrate its negative influence on brain function, thereby suggesting a target for ameliorating cognitive decline in aging.

    2016-06-01

    Full Text Available BrainGain is a common trend within the last ten years in Europe and all-over the world. Managers, key players and scientists are allowed to choose wherever they want to work in the world. As there is a lack of qualified individuals for companies and universities, BrainGain has become a necessity, and mostly – the higher educated individuals are moving away according to a better offer elsewhere in the world. Therefore, a lot of expats are moving around with their families. Many times, the lack of integration at the current place, country or city, is the critical success factor for staying or leaving. Furthermore, if the family does not feel happy in the current location, then the manager or scientist will move away or return home and the investment will be lost.

  11. The exceptional brain of Maurice Ravel.

    Otte, Andreas; De Bondt, Pieter; Van De Wiele, Christophe; Audenaert, Kurt; Dierckx, Rudi

    2003-06-01

    This historical review describes the brain disease which afflicted the great impressionist-classicist composer Maurice Ravel (1875-1937). The usual interpretation of the symptoms Ravel exhibited during his disease is primary progressive aphasia / Pick's disease. Some authors see this as the cause for his lost musical creativity during the last years of his life. By contrast, in our review it is presented why a car accident in 1932, with the probable consequence of a mild to moderate traumatic brain injury, could be the key event in his life, triggering the loss of his ability to compose. In addition, the influence of Ravel's disease on his musical style is evaluated. Although some authors see a link, we try to explain why there is no clear evidence for this.

    Benvenuti, P; Borri, P; Buzzoni, P; Clerici, L; Rossi Monti, M

    1983-01-01

    This study examines the psychological and psychopathological reactions that may appear in a man when his partner aborts. The small amount of literature that exists on the subjects was examined, and several men were, interviewed at the time their partners aborted voluntarely. It turns out that in spite of the man's lack of recognition of any reactions (reinforced by current attitudes and by the scant psychological and medical interest in the subject), there is considerable emotional involvement in the lost parenthood, both for the man and the woman. As revealed by the interviews, this involvement may manifest itself in persecutory or depressive anxiety and psychosomatic symptoms. Moreover, but very rarely, real and typical psychopathological symptoms may appear, such as depression and behavioural disorders. The appearance of these reactions is linked to the problems and conflicts aroused by prospective fatherhood, leading to a comparison between the experiences of fuliwed fatherhood and those of fatherhood lost.

    We have examined the observed currents in the front foils of the JET Faraday cup lost alpha particle diagnostic KA-2. In particular, we have sought to understand the currents during Ohmic plasmas for which the ion flux at the detectors was initially assumed to be negligible. We have considered two sources of this current: plasma ions (both deuterium and impurity) in the vicinity of the detector (including charge exchange neutrals) and photoemission from scattered UV radiation. Based upon modeling and empirical observation, the latter source appears most likely and, moreover, seems to be applicable to the currents in the front foil during ELMy H-mode plasmas. A very thin gold or nickel foil attached to the present detector aperture is proposed as a solution to this problem, and realistic calculations of expected fluxes of lost energetic neutral beam ions during TF ripple experiments are presented as justification of this proposed solution.

    2014-04-22

    Few at-sea behavioural data exist for oceanic-stage neonate sea turtles, a life-stage commonly referred to as the sea turtle 'lost years'. Historically, the long-term tracking of small, fast-growing organisms in the open ocean was logistically or technologically impossible. Here, we provide the first long-term satellite tracks of neonate sea turtles. Loggerheads (Caretta caretta) were remotely tracked in the Atlantic Ocean using small solar-powered satellite transmitters. We show that oceanic-stage turtles (i) rarely travel in Continental Shelf waters, (ii) frequently depart the currents associated with the North Atlantic Subtropical Gyre, (iii) travel quickly when in Gyre currents, and (iv) select sea surface habitats that are likely to provide a thermal benefit or refuge to young sea turtles, supporting growth, foraging and survival. Our satellite tracks help define Atlantic loggerhead nursery grounds and early loggerhead habitat use, allowing us to re-examine sea turtle 'lost years' paradigms.

    The adaptive reconstruction for the lost information of the rectangular image area is very important for the robust transmission and restoration of the image. In this paper, a new reconstruction method based on the Discrete Cosine Transform (DCT) domain has been put forward. According to the low pass character of the human visual system and the energy distribution of the DCT coefficients on the rectangular boundary, the DCT coefficients of the rectangular image area are adaptively selected and recovered. After the Inverse Discrete Cosine Transform (IDCT), the lost information of the rectangular image area can be reconstructed. The experiments have demonstrated that the subjective and objective qualities of the reconstructed images are enhanced greatly than before.

    2008-01-01

    In lost foam casting (LFC) the foam pattern is the key criterion, and the filling process is crucial to ensure the high quality of the foam pattern. Filling which lacks uniformity and denseness will cause various defects and affect the surface quality of the casting. The influential factors of the filling process are realized in this research. Optimization of the filling process, enhancement of efficiency, decrease of waste, etc., are obtained by the numerical simulation of the filling process using a computer. The equations governing the dense gas-solid two-phase flow are established, and the physical significance of each equation is discussed. The Euler/Lagrange numerical model is used to simulate the fluid dynamic characteristics of the dense two-phase flow during the mould filling process in lost foam casting. The experiments and numerical results showed that this method can be a very promising tool in the mould filling simulation of beads' movement.

    Full Text Available Every town hss its own architectural performance. And architecture is not merely a physical landscape of buildings in a town,, as seen by the observer, but it has a deeper mening, which displays the art of structures and constructions. It is a sequence of buildings along the course of its history (Aldo Rossi, 1980. A Town is a complete work of art, performed by men of urban knowledge. Tehe concept of a town or urban workmanship arises from time to time as a work of art in multiple variations, together and according to spirit of the time, included its aspects of belief and religion. The urban work of art or urban artefact is always related to location, historical events and the spesific urban look. Generally a town has particular rythm and dynamics, at least it does not remain static. Therefore it is quite right, when we say, that a town represents the course of its history and technology during the period of its existence. But when we scrutinise alongthe historical and visual systems, it turns out that so many physical and sociqal spaces have been altered with regard to their quality and quantity, as result mis management ot the physical and social spaces by less careful urban reformists. they may bring about certain inbalancy in the system, destroying public imagination and memory about the identity and message conceived at the time of their construction. At the this may affect a condition, commonly called the lost space. Surabaya is one of the larger towns in Indonesia, which afrtime possessed a number of urban artefacts and workmanship. One of which is the Tunjungan Street, designed and developed by the Gemeente Administration of the Duutch as comercial corriodor of the town, with all its advantages and shortcomings.

    ABSTRACT OBJECTIVE To estimate the potential years of life lost by road traffic injuries three years after the beginning of the Decade of Action for Traffic Safety. METHODS We analyzed the data of the Sistema de Informações sobre Mortalidade (SIM – Mortality Information System) related to road traffic injuries, in 2013. We estimated the crude and standardized mortality rates for Brazil and geographic regions. We calculated, for the Country, the proportional mortality according to age groups, education level, race/skin color, and type or quality of the victim while user of the public highway. We estimated the potential years of life lost according to sex. RESULTS The mortality rate in 2013 was of 21.0 deaths per 100,000 inhabitants for the Country. The Midwest region presented the highest rate (29.9 deaths per 100,000 inhabitants). Most of the deaths by road traffic injuries took place with males (34.9 deaths per 100,000 males). More than half of the people who have died because of road traffic injuries were of black race/skin color, young adults (24.2%), individuals with low schooling (24.0%), and motorcyclists (28.5%). The mortality rate in the triennium 2011-2013 decreased 4.1%, but increased among motorcyclists. Across the Country, more than a million of potential years of life were lost, in 2013, because of road traffic injuries, especially in the age group of 20 to 29 years. CONCLUSIONS The impact of the high mortality rate is of over a million of potential years of life lost by road traffic injuries, especially among adults in productive age (early mortality), in only one year, representing extreme social cost arising from a cause of death that could be prevented. Despite the reduction of mortality by road traffic injuries from 2011 to 2013, the mortality rates increased among motorcyclists. PMID:27706375

    Derivation of induced pluripotent stem (iPS) cells is mainly an epigenetic reprogramming process. It is still quite controversial how genomic imprinting is reprogrammed in iPS cells. Thus, we derived multiple iPS clones from genetically identical mouse somatic cells. We found that parentally inherited imprint was variably lost among these iPS clones. Concurrent with the loss of DNA methylation imprint at the corresponding Snrpn and Peg3 imprinted regions, parental origin-specific expression o...

    Full Text Available Attitudes toward traditional and chiropractic medicine were compared using Milgram's lost letter technique. A total of 192 letters were placed on the windshields of vehicles in parking lots at six restaurants and department stores in each of four quadrants of a medium-sized, Southeastern city. These letters were addressed to "Admissions" at either a fictitious Institute of Medicine or Institute of Chiropractic Care. Return addresses included either a male or a female name. Thus, those who found a lost letter were faced with the option of returning or not returning a letter from either a male or a female, addressed to an Institute of traditional or non-traditional medicine. After examining previous studies which had used the lost letter technique, numerous methodological improvements were implemented. For example, letters were randomly assigned to potential drop spots for each of 24 study locations (six study locations in each of four city quadrants, and a Latin square design was used to control for possible order effects in the four study conditions that were implemented. Nearly 65% of the letters (124 of 192 were returned. We found: 1 letters addressed to a fictitious Institute of Chiropractic Care were just as likely to be returned as those addressed to a fictitious Institute of Medicine; 2 letters with female return addresses were as likely to be returned as those with male return addresses; 3 there was no interaction between study conditions; 4 based on what was essentially a replication study, a comparison of the pattern of returns using the first and second cycle of lost letters (n = 96 for each cycle revealed an equivalent pattern of no-difference findings. DOI: 10.2458/azu_jmmss.v1i1.78

    We used 13 years (1995-2007) of capture-mark-recapture data to assess population dynamics of endangered Lost River suckers Deltistes luxatus and shortnose suckers Chasmistes brevirostris in Upper Klamath Lake, Oregon. The Cormack-Jolly-Seber method was used to estimate survival, and information theoretic modeling was used to assess variation due to time, gender, species, and spawning subpopulations. Length data were used to detect multiple year-class failures and events of high recruitment into adult spawning populations. Average annual survival probability was 0.88 for Lost River suckers and 0.76 for shortnose suckers. Mean life span estimates based on these survival rates indicated that Lost River suckers survived long enough on average to attempt reproduction eight times, whereas shortnose suckers only survived to spawn three to four times. Shortnose sucker survival was not only poor in years of fish kills (1995-1997) but also was low in years without fish kills (i.e., 2002 and 2004). This suggests that high mortality occurs in some years but is not necessarily associated with fish kills. Annual survival probabilities were not only different between the two species but also differed between two spawning subpopulations of Lost River suckers. Length composition data indicated that recruitment into spawning populations only occurred intermittently. Populations of both species transitioned from primarily old individuals with little size diversity and consistently poor recruitment in the late 1980s and early 1990s to mostly small, recruit-sized fish by the late 1990s. A better understanding of the factors influencing adult survival and recruitment into spawning populations is needed. Monitoring these vital parameters will provide a quantitative means to evaluate population status and assess the effectiveness of conservation and recovery efforts.

  20. Estimation of Wellbore and Formation Temperatures during the Drilling Process under Lost Circulation Conditions

    2013-01-01

    Full Text Available Significant change of wellbore and surrounding formation temperatures during the whole drilling process for oil and gas resources often leads by annulus fluid fluxes into formation and may pose a threat to operational security of drilling and completion process. Based on energy exchange mechanisms of wellbore and formation systems during circulation and shut-in stages under lost circulation conditions, a set of partial differential equations were developed to account for the transient heat exchange process between wellbore and formation. A finite difference method was used to solve the transient heat transfer models, which enables the wellbore and formation temperature profiles to be accurately predicted. Moreover, heat exchange generated by heat convection due to circulation losses to the rock surrounding a well was also considered in the mathematical model. The results indicated that the lost circulation zone and the casing programme had significant effects on the temperature distributions of wellbore and formation. The disturbance distance of formation temperature was influenced by circulation and shut-in stages. A comparative perfection theoretical basis for temperature distribution of wellbore-formation system in a deep well drilling was developed in presence of lost circulation.

  1. U12 type introns were lost at multiple occasions during evolution

    Directory of Open Access Journals (Sweden)

    2010-02-01

    Full Text Available Abstract Background Two categories of introns are known, a common U2 type and a rare U12 type. These two types of introns are removed by distinct spliceosomes. The phylogenetic distribution of spliceosomal RNAs that are characteristic of the U12 spliceosome, i.e. the U11, U12, U4atac and U6atac RNAs, suggest that U12 spliceosomes were lost in many phylogenetic groups. We have now examined the distribution of U2 and U12 introns in many of these groups. Results U2 and U12 introns were predicted by making use of available EST and genomic sequences. The results show that in species or branches where U12 spliceosomal components are missing, also U12 type of introns are lacking. Examples are the choanoflagellate Monosiga brevicollis, Entamoeba histolytica, green algae, diatoms, and the fungal lineage Basidiomycota. Furthermore, whereas U12 splicing does not occur in Caenorhabditis elegans, U12 introns as well as U12 snRNAs are present in Trichinella spiralis, which is deeply branching in the nematode tree. A comparison of homologous genes in T. spiralis and C. elegans revealed different mechanisms whereby U12 introns were lost. Conclusions The phylogenetic distribution of U12 introns and spliceosomal RNAs give further support to an early origin of U12 dependent splicing. In addition, this distribution identifies a large number of instances during eukaryotic evolution where such splicing was lost.

    Seafloor investigations of slow- and ultraslow-spreading ridges have reported many occurrences of exposed mantle peridotites and gabbroic rocks on the ocean floor. Along the Mid-Atlantic Ridge, these uplifted portions of oceanic crust host high-temperature black smoker-type hydrothermal systems (e.g., Rainbow, Logatchev, Saldanha), and the more distinct low-temperature Lost City Hydrothermal Field (LCHF). Built on a southern terrace of the Atlantis Massif, the LCHF is composed of carbonate-brucite chimneys that vent alkaline and low-temperature (40-90°C) hydrothermal fluids. These fluids are related to serpentinization of mantle peridotites, which together with minor gabbroic intrusions form the basement of the LCHF. Long-lived hydrothermal activity at Lost City led to extensive seawater-rock interaction in the basement rocks, as indicated by seawater-like Sr- and mantle to unradiogenic Nd-isotope compositions of the serpentinites. These high fluid fluxes in the southern part of the massif influenced the conditions of serpentinization and have obliterated the early chemical signatures in the serpentinites, especially those of carbon and sulfur. Compared to reducing conditions commonly formed during the first stages of serpentinization, serpentinization at Lost City is characterized by relatively oxidizing conditions resulting in a predominance of magnetite, the mobilization/dissolution and oxidation of igneous sulfides to secondary pyrite, and the incorporation of seawater sulfate, all leading to high bulk-rock S-isotope compositions. The Lost City hydrothermal fluids contain high concentrations in methane, hydrogen, and low-molecular weight hydrocarbons considered as being produced abiotically. In contrast, organic compounds in the serpentinites are dominated by the occurrences of isoprenoids (pristane, phytane, and squalane), polycyclic compounds (hopanes and steranes), and higher abundances of C16 to C20 n-alkanes indicative of a marine organic input.

The lost natural landscape includes lost gardens of the area, about which our colleague Cerasella Craciun conducted archive research. The lost cultural landscape includes buildings which collapsed in the 1977 earthquake. We developed a digital model of guided tours for these landmarks. First, the lost items are identified on today's map. Second, a game is created in order to identify what replaces them on the historic map. We developed the code for these in Adobe Director and already experimented it for the city of Cologne in Germany, and tested for applicability for the landmarks of the 1755 Lisbon earthquake, where a similar concept is suitable. The nodes of the route are to be mapped as landscape through photography using the COMOB application, which allows inclusion of intangible heritage items such as the world of words.

    The past 15 years have seen a rapid expansion in the number of studies using neuroimaging techniques to investigate maturational changes in the human brain. In this paper, I review MRI studies on structural changes in the developing brain, and fMRI studies on functional changes in the social brain during adolescence. Both MRI and fMRI studies point to adolescence as a period of continued neural development. In the final section, I discuss a number of areas of research that are just beginning and may be the subject of developmental neuroimaging in the next twenty years. Future studies might focus on complex questions including the development of functional connectivity; how gender and puberty influence adolescent brain development; the effects of genes, environment and culture on the adolescent brain; development of the atypical adolescent brain; and implications for policy of the study of the adolescent brain.

  11. Waterborne outbreak of gastroenteritis: effects on sick leaves and cost of lost workdays.

    Directory of Open Access Journals (Sweden)

    Jaana I Halonen

    Full Text Available BACKGROUND: In 2007, part of a drinking water distribution system was accidentally contaminated with waste water effluent causing a gastroenteritis outbreak in a Finnish town. We examined the acute and cumulative effects of this incidence on sick leaves among public sector employees residing in the clean and contaminated areas, and the additional costs of lost workdays due to the incidence. METHODS: Daily information on sick leaves of 1789 Finnish Public Sector Study participants was obtained from employers' registers. Global Positioning System-coordinates were used for linking participants to the clean and contaminated areas. Prevalence ratios (PR for weekly sickness absences were calculated using binomial regression analysis. Calculations for the costs were based on prior studies. RESULTS: Among those living in the contaminated areas, the prevalence of participants on sick leave was 3.54 (95% confidence interval (CI 2.97-4.22 times higher on the week following the incidence compared to the reference period. Those living and working in the clean area were basically not affected, the corresponding PR for sick leaves was 1.12, 95% CI 0.73-1.73. No cumulative effects on sick leaves were observed among the exposed. The estimated additional costs of lost workdays due to the incidence were 1.8-2.1 million euros. CONCLUSIONS: The prevalence of sickness absences among public sector employees residing in affected areas increased shortly after drinking water distribution system was contaminated, but no long-term effects were observed. The estimated costs of lost workdays were remarkable, thus, the cost-benefits of better monitoring systems for the water distribution systems should be evaluated.

  12. Colonial waterbird predation on Lost River and Shortnose suckers in the Upper Klamath Basin

    We evaluated predation on Lost River Suckers Deltistes luxatus and Shortnose Suckers Chasmistes brevirostris by American white pelicans Pelecanus erythrorhynchos and double-crested cormorants Phalacrocorax auritus nesting at mixed-species colonies in the Upper Klamath Basin of Oregon and California during 2009–2014. Predation was evaluated by recovering (detecting) PIT tags from tagged fish on bird colonies and calculating minimum predation rates, as the percentage of available suckers consumed, adjusted for PIT tag detection probabilities but not deposition probabilities (i.e., probability an egested tag was deposited on- or off-colony). Results indicate that impacts of avian predation varied by sucker species, age-class (adult, juvenile), bird colony location, and year, demonstrating dynamic predator–prey interactions. Tagged suckers ranging in size from 72 to 730 mm were susceptible to cormorant or pelican predation; all but the largest Lost River Suckers were susceptible to bird predation. Minimum predation rate estimates ranged annually from Suckers and from Suckers, and predation rates were consistently higher on suckers in Clear Lake Reservoir, California, than on suckers in Upper Klamath Lake, Oregon. There was evidence that bird predation on juvenile suckers (species unknown) in Upper Klamath Lake was higher than on adult suckers in Upper Klamath Lake, where minimum predation rates ranged annually from 5.7% to 8.4% of available juveniles. Results suggest that avian predation is a factor limiting the recovery of populations of Lost River and Shortnose suckers, particularly juvenile suckers in Upper Klamath Lake and adult suckers in Clear Lake Reservoir. Additional research is needed to measure predator-specific PIT tag deposition probabilities (which, based on other published studies, could increase predation rates presented herein by a factor of roughly 2.0) and to better understand biotic and abiotic factors that regulate sucker susceptibility to

  13. Affect and Nostalgia in Eva Hoffman’s Lost in Translation

    Full Text Available This article examines the affective terrain of Poland, Canada, and the US in Eva Hoffman’s autobiographical account of her migration and exile in Lost in Translation: A Life in a New Language (1989, the text that launched Hoffman’s reputation as a writer and intellectual. Hoffman’s Jewish family left Poland for Vancouver in 1959, when restrictions on emigration were lifted. Hoffman was 13 when she emigrated to Canada, where she lived until she went to college in the US and began her career. Lost in Translation represents her trajectory in terms of “Paradise,” “Exile,” and “The New World,” and the narrative explicitly thematizes nostalgia. While Hoffman’s nostalgia for post-war Poland has sometimes earned censure from critics who draw attention to Polish anti-Semitism and the failings of Communism, this article stresses how Hoffman’s nostalgia for her Polish childhood is saturated with self-consciousness and an awareness of the politics of remembering and forgetting. Thus, Hoffman’s work helps nuance the literary and critical discourse on nostalgia. Drawing on theories of nostalgia and affect developed by Svetlana Boym and Sara Ahmed, and on Adriana Margareta Dancus’s notion of “affective displacement,” this article examines Hoffman’s complex understanding of nostalgia. It argues that nostalgia in Lost in Translation is conceived as an emotion which offers the means to critique cultural practices and resist cultural assimilation. Moreover, the lyricism of Hoffman’s autobiography becomes a mode for performing the ambivalence of nostalgia and diasporic feeling.

The objective of this study was to assess the empirical significance of absenteeism and presenteeism in terms of production loss using the case of rheumatoid arthritis (RA. Selected modules from the Health and Labor Questionnaire were applied in a cross-sectional study of 3,704 patients with RA. The costs of absenteeism and presenteeism were estimated using the Human Capital approach, and the impact of including multipliers adjusting for the productivity effect of a workers’ absence or impaired presenteeism on societal productivity was demonstrated. RA-related absenteeism over the last 14 days was 22.31 hours (standard deviation [SD], 26.51 with a resulting cost of €473 (SD, 575 and €762 (SD, 926 depending on whether a multiplier was included. Presenteeism was found to affect 7.98 (SD, 3.24 working days over the last 14 days with a resulting cost of €168 (SD, 203 and €203 (SD, 245, again depending on whether a multiplier was included. Overall, this article demonstrates that the value of lost production due to RA could be subject to an almost factor 2 increase if productivity effects of presenteeism and general multipliers are included.Keywords: work limitations, Health and Labor Questionnaire, productivity, production loss

  15. Complications of gallstones: the Mirizzi syndrome, gallstone ileus, gallstone pancreatitis, complications of "lost" gallstones.

    Gallstones cause various problems besides simple biliary colic and choplecystitis. With chronicity of inflammation caused by gallstone obstruction of the cystic duct, the gallbladder may fuse to the extrahepatic biliary tree, causing Mirizzi syndrome, or fistulize into the intestinal tract, causing so-called gallstone ileus. Stones may pass out of the gallbladder and travel downstream through the common bile duct to obstruct the ampulla of Vater resulting in gallstone pancreatitis, or pass out of the gallbladder inadvertently during surgery, resulting in the syndromes associated with lost gallstones. This article examines these varied and complex complications, with recommendations for management based on the literature, the data, and perhaps some common sense.

    We analyze Hawking evaporation of the Callen-Giddings-Harvey-Strominger (CGHS) black holes from a quantum geometry perspective and show that information is not lost, primarily because the quantum space-time is sufficiently larger than the classical. Using suitable approximations to extract physics from quantum space-times we establish that: i)future null infinity of the quantum space-time is sufficiently long for the the past vacuum to evolve to a pure state in the future; ii) this state has a finite norm in the future Fock space; and iii) all the information comes out at future infinity; there are no remnants.

    Humor study enjoys a long history with a variety of theories and methods. Among them, the pragmatic approach is a relatively new and vigorous perspective. Scholars have adopted the cooperative principle and relevance theory to explain humor. However, as to studying humor from the perspective of pragmatic presupposition, very few researches have been done in this regard. Such being the case, this paper will use presupposition as a tool to analyze humor in Lost in Thailand which is a sensational comedy in China. By analyzing cases from this film, the paper aims to explore how presupposition functions in the production of humorous effect, and to provide some new insights into humor study.

    In the northern Basin &Range, alluvial fans developed along the Lost River range-front consist of several distinct inset fan segments with concave-up radial profiles. Multiple large radius (>5 km), shallow (2- 3°), alluvial fans extend across and beyond the active, ~140-km-long, normal Lost River fault. These large fans are relict features, formed by major sheetfloods that occurred intermittently between ~15-180 ka. More recent deposition has been dominated by debris-flows that form small-radius (cuts through gravelly fan deposits, indicates that the fan soils are geochemically suitable for uranium-series dating (median U=7ppm, 232Th=0.09ppm, 232Th/230Th=154). 230Th/U analysis of these calcic soils can thus provide precise temporal constraints on intervals of surface stability and subsequent soil formation. The oldest fan surface (Qfo1, 178+/-8 ka), exposed within the footwall of the trench, suggests an interval of surface stability, indicating that the fan was likely abandoned due to incision early in MIS 6. Incision may have resulted from surface faulting along the Arco segment of the Lost River fault, but could relate to changes in stream power or sediment supply associated with climatic change or with auto-cyclic variations within the drainage basin. A younger incised and faulted fan surface (Qfo2, 69+/-6 ka), likely represents active alluviation at the beginning of MIS 4 and, since it formed as hanging-wall alluvial gravel, provides age limits on an episode of fault displacement between Qfo1 and Qfo2. In situ pedogenic carbonate coats on sub-angular gravels within the colluvial fault wedge date at 68+/-2 ka, suggesting that either faulting occurred soon after Qfo2 stabilized or that soil carbonate coats were recycled into the colluvial wedge from the faulted surface. Further studies in the Lost River Range will assess the timing of fan deposition, surface stabilization and fault activity since the late Pleistocene using coupled application of Optically

  20. Two Combinatorial Proofs, and a Generalization, of an Identity from Ramanujan's Lost Notebook

    Levande, Paul

    2009-01-01

    We examine an identity originally stated in Ramanujan's "lost notebook" and first proven, algebraically, by Andrews. We first show that the identity can be rewritten, using minor algebraic manipulation, into an identity that can be proven with a direct bijection. We provide such a bijection using a generalization of a standard bijection from partition theory. We then show that this proof implies further generalizations of the original identity, and that when these generalizations are written in the identity's original form, they can be proven using the involution principle. We give such an involution explicitly, which also provides an involution-based proof of the original identity.

    Children with autism may not develop safety skills (e.g., help-seeking behaviors) without explicit teaching. One potentially hazardous situation is when a child with autism becomes separated from caregivers in a retail establishment or other public setting. The purpose of this study was to evaluate a treatment package (rules, role playing, and praise) delivered in the natural environment for teaching 3 boys with autism to seek assistance from store employees when they became lost. Treatment was effective, and help-seeking behaviors generalized to untrained stores for all participants.

    To evaluate the burden of air pollution on years of life lost (YLL) in addition to mortality, we conducted a time series analysis based on the data on air pollution, meteorological conditions and 163,704 non-accidental deaths of Ningbo, China, 2009-2013. The mean concentrations of particulate matter with aerodynamic diameter air pollution lasted for four days (lag 0-3), and were more significant in the elderly than in the young population for both outcomes. These findings clarify the burden of air pollution on YLL and highlight the importance and urgency of air pollution control in China.

    An improved method of filling a molding flask with sand and compacting the sand around a refractory-coated foam mold pattern has been developed for incorporation into the lost-foam metal-casting process. In comparison with the conventional method of sand filling and compaction, this method affords more nearly complete filling of the space around the refractory-coated foam mold pattern and more thorough compaction of the sand. In so doing, this method enables the sand to better support the refractory coat under metallostatic pressure during filling of the mold with molten metal.

    @@ The American poet Robert Frost (1874-1963) suggested that poetry gets lost in translation, an opinion that unfortunately has been widely publicised. This view, of course, is a conceit: not only does poetry NOT always get lost in translation, often it is through translation that poetry flourishes. For translation is one of the principal ways in which a literature can reinvigorate itself, can look outwards at other forms of writing and discover and then develop those forms.

    Full Text Available For several decades, the Economic Order Quantity (EOQ model and its variations have received much attention from researchers. Recently, there has been an investigation into an EOQ model incorporating effect of units lost due to deterioration in infinite planning horizon with crisp decision environment. Accounting for holding and ordering cost, as has traditionally been the case of modeling inventory systems in fuzzy environment are investigated which are not precisely known and defined on a bounded interval of real numbers. The question is how reliable are the EOQ models when items stocked deteriorate one time. This paper introduces Fuzzy Economic Order Quantity (FEOQ model in which it assumes that units lost due to deterioration is included in the objective function to properly model the problem in finite planning horizon. The numerical analysis shows that an appropriate fuzzy policy can benefit the retailer and that is significant, especially for deteriorating items is shown to be superior to that of crisp decision making. A computational algorithm using LINGO 13.0 and MATLAB (R2009a software are developed to find the optimal solution. Sensitivity analysis of the optimal solution is also studied and managerial insights are drawn which shows the influence of key model parameters.

  17. The lost Gemeinschaft: how people working with the elderly explain loneliness.

    Schirmer, Werner; Michailakis, Dimitris

    2015-04-01

    We conducted a qualitative interview study with people of different professions working with lonely elderly people. The rationale of the study was to examine how these respondents explain loneliness among the elderly. The present article focuses on the social explanations, i.e. explanations that identify causes of loneliness in the structure of modern society. We found that many of the social explanations given are aspects of a more encompassing and general pattern underlying all the reasoning about loneliness among the elderly. This pattern is the expression of two contrasting images of society which the classical sociologist Ferdinand Tönnies termed Gemeinschaft (community) and Gesellschaft (society). The former refers to traditional or small-size rural communities characterized by high degrees of social cohesion, integration, solidarity, proximity and familiarity, whereas the latter refers to functional differentiation, distance, individualization, exchanged-based social relations and anonymity. Loneliness among the elderly is explained by the lack of Gemeinschaft and its characteristics in contemporary society. This explanatory pattern goes hand in hand with a critical view of contemporary society and a nostalgic yearning for the lost communities of past societies, where inhabitants find their staked-out place and sense of belonging, and thus loneliness hardly seems to occur. We summarized this view under the label the "lost Gemeinschaft".

    Full Text Available This paper examines the Bourne trilogy to explore several characteristics of what we term the bioconvergent age. First, we consider the imagined and actual interfaces of bioconvergence—of body, gadgetry, and electronic communications. We explore the ways in which the bioconvergent tendencies represented in and by Bourne reflect and cultivate a cultural unconscious deeply seduced by and imbricated in surveillant governmentality. Second, we consider the ways in which the trilogy achieves its effects through the deployment of both hyperrealism and verisimilitude. In this context, we explore the filmic interpellation of audiences into a fantasy of omnipotence and omni-science, on the one hand, and the underlying phantasy of a zero-sum world that uncouples morality from affect, on the other. Thus, we consider the ways in which Bourne articulates two interlinked phenomena—a distinctively American romance with the sociopathic/heroic subject and a paranoid, dystopic world that is and seems seductively real. Our third theme is the Bourne journey through an obsessional spiral of paranoia, action, and reaction. Here we explore the trilogy as a social description of the expulsive and retentive tendencies of the bioconvergent age, where the demand for instantaneity drives out all other considerations (morality, reason, connection and where the lost subject, in his interminable quest for himself, remains lost.

    The effect of germ tube induction on the antigenic variability in C.albicans was studied in strains from blood cultures (Group I) and superficial candidiasis (Group II). When compared by immunoblotting with a rabbit antiserum, antigenic extracts from Group I strains grown as blastospores showed a higher reactivity than that of Group II strains. Major bands in Group I strains (45-47, 33, 30 kDa) were continuously expressed through the subcultures in vitro but, with the exception of the 45 kDa band, the reactivity of all of them decreased or disappeared after the tenth subculture in Group II strains. The induction of the germ tubes produced the re-expression of the antigens lost during subculture in the yeast form, the effect being very clear in Group II strains. The re-expression by C. albicans germ tubes of antigens lost during subculture of blastospores in vitro and the higher reactivity shown by Group I strains grown in mycelial phase should be taken into consideration when a test to detect anti-C. albicans antibodies is to be developed.

    NONE

    2006-06-29

    When William Shakepeare wrote Love's Labour's Lost he would have used light from tallow candles at a cost (today) of 12,000 British pounds per million-lumen hours. The same amount of light from electric lamps now costs only 2 pounds! But today's low-cost illumination still has a dark side. Globally, lighting consumes more electricity than is produced by either hydro or nuclear power and results in CO2 emissions equivalent to two thirds of the world's cars. A standard incandescent lamp may be much more efficient than a tallow candle, but it is far less efficient than a high-pressure sodium lamp. Were inefficient light sources to be replaced by the equivalent efficient ones, global lighting energy demand would be up to 40% less at a lower overall cost. Larger savings still could be realised through the intelligent use of controls, lighting levels and daylight. But achieving efficient lighting is not just a question of technology; it requires policies to transform current practice. This book documents the broad range of policy measures to stimulate efficient lighting that have already been implemented around the world and suggests new ways these could be strengthened to prevent light's labour's from being lost.

  1. Brightness Independent 4-Star Matching Algorithm for Lost-in-Space 3-Axis Attitude Acquisition

    2006-01-01

    A star identification algorithm was developed for a charge-coupled device (CCD) or complementary metal-oxide-semiconductor (CMOS) autonomous star tracker to acquire 3-axis attitude information for a lost-in-space spacecraft. The algorithm took advantage of an efficient on-board database and an original "4-star matching" pattern recognition strategy to achieve fast and reliable star identification. The on-board database was composed of a brightness independent guide star catalog (mission catalog) and a K-vector star pair catalog. The star pattern recognition method involved direct location of star pair candidates and a simple array matching procedure. Tests of the algorithm with a CMOS active pixel sensor (APS) star tracker result in a 99.9% success rate for star identification for lost-in-space 3-axis attitude acquisition when the angular measurement accuracy of the star tracker is at least 0.01°. The brightness independent algorithm requires relatively higher measurement accuracy of the star apparent positions that can be easily achieved by CCD or CMOS sensors along with subpixel centroiding techniques.

  2. Genomic imprinting is variably lost during reprogramming of mouse iPS cells.

    2013-09-01

    Derivation of induced pluripotent stem (iPS) cells is mainly an epigenetic reprogramming process. It is still quite controversial how genomic imprinting is reprogrammed in iPS cells. Thus, we derived multiple iPS clones from genetically identical mouse somatic cells. We found that parentally inherited imprint was variably lost among these iPS clones. Concurrent with the loss of DNA methylation imprint at the corresponding Snrpn and Peg3 imprinted regions, parental origin-specific expression of the Snrpn and Zim1 imprinted genes was also lost in these iPS clones. This loss of parental genomic imprinting in iPS cells was likely caused by the reprogramming process during iPS cell derivation because extended culture of iPS cells did not lead to significant increase in the loss of genomic imprinting. Intriguingly, one to several paternal chromosomes appeared to have acquired de novo methylation at the Snrpn and Zac1 imprinted regions in a high percentage of iPS clones. These results might have some implications for future therapeutic applications of iPS cells. Since DNA methylation imprint can be completely erased in some iPS clones at multiple imprinted regions, iPS cell reprogramming may also be employed to dissect the underlying mechanisms of erasure, reacquisition and maintenance of genomic imprinting in mammals.

  3. Paradise Lost: The relationships between neurological and psychological changes in nicotine-dependent patients.

    2014-04-01

    The neural reward circuit and cognitive distortion play an important role in addiction; however, the relationship between the two has not yet been addressed. In this article, we review recent findings on nicotine dependence and propose a novel hypothesis. Previous research using functional magnetic resonance imaging (fMRI) has shown that while activation of the reward circuit (ventral striatum) appears in response to tobacco-related rewards in nicotine dependence, responses to rewards other than tobacco (e.g. food and money) are reduced. Moreover, this change is observed at the very early stages of smoking, even when a person has smoked fewer than 10 cigarettes in his/her lifetime. Thus, we propose the following hypothesis, called the Paradise Lost theory: given addicts' lower ventral striatal responses to non-tobacco rewards, nicotine addiction disables smokers from sensing the pleasures of ordinary life (the Paradise Lost state). However, since smokers do not notice this, they produce an overestimation of tobacco (cognitive distortion), such that they do not have many pastimes other than smoking or feel that quitting smoking would reduce the happiness and pleasure and increase the difficulty of life. Cognitive distortion thus makes it difficult for smokers to take the initiative to quit smoking and even causes relapse after smoking cessation. This theory furthers our understanding of addiction and could improve our approach to the prevention and treatment of addiction.

    Full Text Available The article analyses the effect of refractory coating permeability on the process of casting manufacture by the Lost Foam technique. Theanalysis was focussed on simulation tests examining the effect of coating permeability on the mould cavity filling rate, pressure in gas gap, and the size of this gap. In simulation tests of the Lost Foam Process, a mathematical model of the process presented in this study and the author’s own computation algorithm were used. The computations have proved that with increasing permeability of the protective coating, the pouring rate increases, too, while pressure of gas in the gas gap and the size of the gap are decreasing. The increasing pouring rate ensures correct making of castings, even if their shape is very intricate and the wall cross-sections are very small. Smaller size of the gas gap and lower gas pressure in the gap reduce the risk of mould damage. The author’s own investigations confirmed the importance of the refractory coating permeability and its effect on the casting process, mould pouring rate - in particular.

    Full Text Available Introduction. Traumatic brain injuries have major socio-economic importance due to their frequency, high mortality and serious consequences. According to their nature the consequences of these injuries may be classified as neurological, psychiatric and esthetic. Various lesions of brain structures cause neurological consequences such as disturbance of motor functions, sensibility, coordination or involuntary movements, speech disturbances and other deviations, as well as epilepsy. Psychiatric consequences include cognitive deficit, emotional disturbances and behavior disturbances. Criminal-legal aspect of traumatic brain injuries and litigation. Criminal-legal aspect of traumatic brain injuries expertise understands the qualification of these injuries as mild, serious and qualified serious body injuries as well as the expertise about the mechanisms of their occurrence. Litigation expertise includes the estimation of pain, fear, diminished, i.e. lost vital activity and disability, esthetic marring, and psychological suffer based on the diminished general vital activity and esthetic marring. Competence and timing of expertise. Evaluation of consequences of traumatic brain injuries should be performed only when it can be positively confirmed that they are permanent, i.e. at least one year after the injury. Expertise of these injuries is interdisciplinary. Among clinical doctors the most competent medical expert is the one who is in charge for diagnostics and injury treatment, with the recommendation to avoid, if possible, the doctor who conducted treatment. For the estimation of general vital activity, the neurological consequences, pain and esthetic marring expertise, the most competent doctors are neurosurgeon and neurologist. Psychological psychiatric consequences and fear expertise have to be performed by the psychiatrist. Specialists of forensic medicine contribute with knowledge of criminal low and legal expertise.

    2016-11-01

    Brain tumors are the commonest solid tumor in children, leading to significant cancer-related mortality. Several hereditary syndromes associated with brain tumors are nonfamilial. Ionizing radiation is a well-recognized risk factor for brain tumors. Several industrial exposures have been evaluated for a causal association with brain tumor formation but the results are inconclusive. A casual association between the common mutagens of tobacco, alcohol, or dietary factors has not yet been established. There is no clear evidence that the incidence of brain tumors has changed over time. This article presents the descriptive epidemiology of the commonest brain tumors of children and adults.

  9. The influence of the parameters of lost foam process on the quality of aluminum alloys castings

    2010-01-01

    Full Text Available This paper presents the research results of application of Lost foam process for aluminum alloys castings of a simple geometry. The process characteristic is that patterns and gating of moulds, made of polymers, stay in the mould till the liquid metal inflow. In contact with the liquid metal, pattern intensely and in relatively short time decomposes and evaporates, which is accompanied by casting crystallization. As a consequence of polymer pattern decomposition and evaporation a great quantity of liquid and gaseous products are produced, which is often the cause of different types of casting errors. This paper presents the results of a research with a special consideration given to detecting and analyzing the errors of castings. In most cases the cause of these errors are defects of polymer materials used for evaporable patterns production, as well as defects of materials for refractory coatings production for polymer patterns. The researches have shown that different types of coatings determine properties of the obtained castings. Also, the critical processing parameters (polymer pattern density, casting temperature, permeability of refractory coating and sand, construction of patterns and gating of moulds significantly affect on castings quality. During the research a special consideration was given to control and optimization of these parameters with the goal of achieving applicable castings properties. The study of surface and internal error of castings was performed systematically in order to carry out preventive measures to avoid errors and minimize production costs. In order to achieve qualitative and profitable castings production by the method of Lost foam it is necessary to reach the balance in the system: evaporable polymer pattern - liquid metal - refractory coating - sandy cast in the phase of metal inflow, decomposition and evaporation of polymer pattern, formation and solidification of castings. By optimizing the processing

    Full Text Available Abstract Background A core function of local health departments is to conduct health assessments. The analysis of death certificates provides information on diseases, conditions, and injuries that are likely to cause death – an important outcome indicator of population health. The expected years of life lost (YLL measure is a valid, stand-alone measure for identifying and ranking the underlying causes of premature death. The purpose of this study was to rank the leading causes of premature death among San Francisco residents, and to share detailed methods so that these analyses can be used in other local health jurisdictions. Methods Using death registry data and population estimates for San Francisco deaths in 2003–2004, we calculated the number of deaths, YLL, and age-standardized YLL rates (ASYRs. The results were stratified by sex, ethnicity, and underlying cause of death. The YLL values were used to rank the leading causes of premature death for men and women, and by ethnicity. Results In the years 2003–2004, 6312 men died (73,627 years of life lost, and 5726 women died (51,194 years of life lost. The ASYR for men was 65% higher compared to the ASYR for women (8971.1 vs. 5438.6 per 100,000 persons per year. The leading causes of premature deaths are those with the largest average YLLs and are largely preventable. Among men, these were HIV/AIDS, suicide, drug overdose, homicide, and alcohol use disorder; and among women, these were lung cancer, breast cancer, hypertensive heart disease, colon cancer, and diabetes mellitus. A large health disparity exists between African Americans and other ethnic groups: African American age-adjusted overall and cause-specific YLL rates were higher, especially for homicide among men. Except for homicide among Latino men, Latinos and Asians have comparable or lower YLL rates among the leading causes of death compared to whites. Conclusion Local death registry data can be used to measure, rank, and

    2008-03-01

    In the framework of a research aiming to assess the suitability of neutron/x-ray non-destructive techniques for the characterization of archaeological objects, two bronze items were studied by neutron diffraction. The origins of two small statues are, respectively, Egyptian (XXI-XXX Dynasties, c1070-343 B.C.) and Etruscan (IV-III centuries B.C.), belonging to a private collection. By hard x-ray diffraction we previously verified that both statuettes have a coarse microstructure (big grains). From historical considerations we believe that both items were produced by solid lost wax processes of casting. This processing technique does not completely justify the presence of microstrains; as a consequence, due to unexpected neutron diffraction peak broadening, a non-uniform Sn wt% is suspected. In the present work we discuss this deduction by means of Rietveld analysis of the neutron diffraction profiles.

    Adams-Silvan, A; Silvan, M

    1994-06-01

    This paper presents extensive clinical data illustrating the case of a middle-aged woman, who as a child participated in an extended sexual relationship with her elder brother. The patient suffered from an hysterical personality disorder with somatic distress and a compulsion to repeat disastrous social and work situations. In her treatment, the patient re-enacted the seduction and subsequent experience in various ways. The analysis and understanding of her symptoms, social problems and re-enactments in the transference strongly suggested that the trauma of her seduction was the result of the loss of precociously stimulated and experienced pleasure rather than loss of impulse control. The compulsion to repeat apparently represented the wish not only to master, but the desire to return to the pleasure of the experience as a true compromise formation. Although many other dynamics were of course operative, interpretations of her wish to recreate the lost pleasures were most helpful.

    Global Positioning System (GPS) technology has been used widely in transsportation industry to help company in managing taxis. The most popular GPS utilization for taxi company is to identify the position of taxis and monitor theirs the mobility. Nowdays, data collected from GPS tracker is combined with data from taxi meter are analyzed to provide region information regarding potential passengers. Zicheng Liao’s proposed a system based on GPS taxi data to detect anomalous area/region which was then interpreted as region with to predict rare passengers. The system was developed based on conditional random field (CRF) method and features position, velocity, passenger loading information. Our research was aimed to develop tool based on GPS data to detect potential lost person. We motivated by Liao research and modified the algorithms and features of CRF. Our experiments showed that the system has precision of 98.86% and recall of 87.478%.

    The Big Lost River basin occupies about 1,400 square miles in south-central Idaho and drains to the Snake River Plain. The economy in the area is based on irrigation agriculture and stockraising. The basin is underlain by a diverse-assemblage of rocks which range, in age from Precambrian to Holocene. The assemblage is divided into five groups on the basis of their hydrologic characteristics. Carbonate rocks, noncarbonate rocks, cemented alluvial deposits, unconsolidated alluvial deposits, and basalt. The principal aquifer is unconsolidated alluvial fill that is several thousand feet thick in the main valley. The carbonate rocks are the major bedrock aquifer. They absorb a significant amount of precipitation and, in places, are very permeable as evidenced by large springs discharging from or near exposures of carbonate rocks. Only the alluvium, carbonate rock and locally the basalt yield significant amounts of water. A total of about 67,000 acres is irrigated with water diverted from the Big Lost River. The annual flow of the river is highly variable and water-supply deficiencies are common. About 1 out of every 2 years is considered a drought year. In the period 1955-68, about 175 irrigation wells were drilled to provide a supplemental water supply to land irrigated from the canal system and to irrigate an additional 8,500 acres of new land. Average. annual precipitation ranged from 8 inches on the valley floor to about 50 inches at some higher elevations during the base period 1944-68. The estimated water yield of the Big Lost River basin averaged 650 cfs (cubic feet per second) for the base period. Of this amount, 150 cfs was transpired by crops, 75 cfs left the basin as streamflow, and 425 cfs left as ground-water flow. A map of precipitation and estimated values of evapotranspiration were used to construct a water-yield map. A distinctive feature of the Big Lost River basin, is the large interchange of water from surface streams into the ground and from the

    2014-01-01

    Full Text Available A two-patch model, SEi1,…,EinIiLi,  i=1,2, is used to analyze the spread of tuberculosis, with an arbitrary number n of latently infected compartments in each patch. A fraction of infectious individuals that begun their treatment will not return to the hospital for the examination of sputum. This fact usually occurs in sub-Saharan Africa, due to many reasons. The model incorporates migrations from one patch to another. The existence and uniqueness of the associated equilibria are discussed. A Lyapunov function is used to show that when the basic reproduction ratio is less than one, the disease-free equilibrium is globally and asymptotically stable. When it is greater than one, there exists at least one endemic equilibrium. The local stability of endemic equilibria can be illustrated using numerical simulations. Numerical simulation results are provided to illustrate the theoretical results and analyze the influence of lost sight individuals.

  16. Symmetrization in jellyfish: reorganization to regain function, and not lost parts.

    Abrams, Michael J; Goentoro, Lea

    2016-02-01

    We recently reported a previously unidentified strategy of self-repair in the moon jellyfish Aurelia aurita. Rather than regenerating lost parts, juvenile Aurelia reorganize remaining parts to regain essential body symmetry. This process that we called symmetrization is rapid and frequent, and is not driven by cell proliferation or cell death. Instead, the swimming machinery generates mechanical forces that drive symmetrization. We found evidence for symmetrization across three other species of jellyfish (Chrysaora pacifica, Mastigias sp., and Cotylorhiza tuberculata). We propose reorganization to regain function without recovery of initial morphology as a potentially broad class of self-repair strategy beyond radially symmetrical animals, and discuss the implications of this finding on the evolution of self-repair strategies in animals.

    2003-01-01

    Full Text Available This paper discuss the influence of the refractory cordierite lining on the structure and mechanical properties of Al-Si and Al-Cu casings obtained from the Lost foam casting process. So far there has not been any report of the research on cordierite lining in the literature and moreover the cordierite ceramics have never been used in foundries. In the light of these facts this paper investigates the possibility of using cordierite for manufacturing evaporable model refractory linings. Our results indicate that the application of cordierite ceramics is comparable to talc-based refractory linings in both Al-Cu and Al-Si castings, while cordierites are favorable in Al-Cu case due to their higher melting temperature.

  18. Modelling small-area inequality in premature mortality using years of life lost rates

    2013-04-01

    Analysis of premature mortality variations via standardized expected years of life lost (SEYLL) measures raises questions about suitable modelling for mortality data, especially when developing SEYLL profiles for areas with small populations. Existing fixed effects estimation methods take no account of correlations in mortality levels over ages, causes, socio-ethnic groups or areas. They also do not specify an underlying data generating process, or a likelihood model that can include trends or correlations, and are likely to produce unstable estimates for small-areas. An alternative strategy involves a fully specified data generation process, and a random effects model which "borrows strength" to produce stable SEYLL estimates, allowing for correlations between ages, areas and socio-ethnic groups. The resulting modelling strategy is applied to gender-specific differences in SEYLL rates in small-areas in NE London, and to cause-specific mortality for leading causes of premature mortality in these areas.

    2012-01-01

    Full Text Available The success of a complete denture relies on the principles of retention, stability and support. The prosthodontist skill lies in applying these principles efficiently in critical situations. Severely resorbed maxillary edentulous ridges that are narrow and constricted with increased inter ridge space provide decreased support, retention and stability. The consequent weight of the processed denture only compromises them further. This article describes a case report of an edentulous patient with resorbed ridges where a simplified technique of fabricating a hollow maxillary complete denture using lost salt technique was used for preservation of denture bearing areas. The hollowing of the denture reduces the weight of the denture, thereby enhancing stability and retention, reducing the further resorption of the jaws.

    2003-02-04

    This CFD Project has led to a new commercial software package (Arena-flow-eps) for advanced engineering of lost foam pattern formation. Specifically, the new software models all fluid/particle/thermal phenomena during both the bead-blowing and the pattern-fusing cycles--within a single, integrated computational tool. Engineering analysis with Arena-flow-eps will enable foundries to now obtain desirable foam pattern characteristics in a reliable (consistent) manner, aided by an understanding of the fundamental fluid/thermal physics of the process. This will lead to significant reductions in casting scrap and energy usage, as well as enable future castings to satisfy stringent requirements on high-power-density and low-emissions in tomorrow's automotive and watercraft engines.

    BACKGROUND: It has been debated whether psychological stress causes cancer, but the scientific evidence remains contradictory. The objective of this study was to investigate whether the death of a child is related to cancer risk in bereaved parents. METHODS: The authors undertook a follow-up study...... based on national registers. All 21,062 parents who lost a child from 1980 to 1996 were recruited for the exposed cohort together with 293,745 randomly selected, unexposed parents. Cox proportional hazards regression models were used to evaluate the relative risk of cancer incidence up to 18 years after....../immune-related malignancies (ICD7 codes 155, 171, 191, 200-202, and 204), lymphatic/hematopoietic malignancies (ICD7 codes 200-205), and hormone related malignancies (ICD7 codes 170, 172, 175, and 177). RESULTS: The authors observed a slightly increased overall cancer risk in bereaved mothers (relative risk [RR], 1.18; 95...

    In order to cope with the diagnosis of mental illness in a family member, siblings may be forced to adjust their roles in the family. Taking into account the crucial role that some siblings play in caregiving for the mentally ill especially when the parents are no longer available, it is imperative to develop awareness of their unique needs and address them. Thirty-three adult siblings of people diagnosed with a mental disorder completed the Role Behaviour Inventory (RBI) and a general questionnaire including open-ended questions regarding the roles they played in their families of origin. Findings from the inventory and general questionnaire suggest that the well siblings score higher on two roles, the Hero and Lost Child, and lower on the Mascot and Scapegoat roles relative to a comparison group (N = 33). Being a sibling caregiver emerged as a risk factor to assume certain dysfunctional roles in the family. Implications for future research and therapy are discussed.

    2012-04-01

    Full Text Available The article presents analysis of the influence of ingate size on the Lost Foam casting process. In particular, analysis of simulation tests has been carried out to determine the ingate size influence on the rate of filling of the mould cavity, pressure in the gas gap and size of the gas gap. A specially prepared mathematical model of the process and an original calculation algorithm were used in simulation tests of full-mould casting. The tests have indicated that the increase of the ingate size results in the increase of filling rate and increase of pressure of gases in the gas gap. However, significant influence on mould cavity filling occurs only when the ingate size is less than ~1 cm2.

    A deterministic model of tuberculosis (TB) in sub-Saharan Africa including undetected and lost-sight cases is presented and analyzed. The model is shown to exhibit the phenomenon of backward bifurcation, when a stable disease-free equilibrium co-exists with one or more stable endemic equilibrium points when the associated basic reproduction number (R0) is less than unity. Analyzing the model obviously reveals that exogenous reinfection plays a key role on the existence of backward bifurcation. However, an analysis of the ranges of exogenous reinfection suggested that backward bifurcation occurs only for very high and unrealistic ranges of the exogenous reinfection rate. Random perturbation of reinfection rates was performed to gain insight into the role of this latter on the stability of the disease free equilibrium.

    Full Text Available This research examines Mexican firm structure and performance during the years 2003 and 2008, using data from the 2004 and 2009 Economic Census. We find that the poor firm structure of year 2003 is even worst in 2008. Detailed analysis of variables relevant for economic performance and future development, confirms that the period 2001-2010 was indeed a third lost decade, and that the current firm structure makes it impossible to achieve a meaningful economic development for the 2011-2020 decade. Results also confirm one of the main thesis in current literature, namely, that lack of investment in physical capital is one of the main causes of economy stagnation.

    Full Text Available The work presents the results of investigation centred around the selection of a ceramic slurry composition if ceramic fibre is applied as a component of moulding material used for the lost wax technology. Producing a ceramic material of assumed parameters demands for changing the surface properties of the mineral grains. The critical concentration of solid particles or the gel point depends on the size of mineral particles, their shape and ability to aggregate. This ability has been achieved by modifying their surface properties by adding some polymer and the wetting agent (surfactant, which are adsorbed. Using the fibre material has required developing a method of its applying to the pattern set. The technology of multi-layer spraying has been recognised as the most advantageous one. The performed laboratory experiments have allowed for determining both the material composition and the parameters of its applying, such as air pressure, nozzle diameter, and the spraying distance for gravity pneumatic spraying gun.

    2012-10-01

    Hidden childhood trauma beneath poignant memories is a central aspect of In Search of Lost Time. Marcel Proust's magnum opus may be psychoanalytically understood as an extraordinary literary transformation of severe trauma and associated unconscious confiicts. Proust's nearly fatal childhood asthma and concomitant medical mistreatment contributed to an intense ambivalent bond and bondage with his mother, replicated in the ambivalent relationships depicted in his novel. The retrieved and re-created past is relived in the novel's fantasy playground of time and space. Proust's intuitive grasp of signiflcant aspects of time, memory, trauma, and transference was consistent with psychoanalytic thought. In the vast novel, the narcissistic mortiflcation and losses of the protagonist are mourned, worked through, and partially redeemed. I interpret the famed joyous tasting of the madeleine in tea as an artfully disguised, temporally displaced, and affective reversal of life-threatening trauma. This article probes the role of Proust's intractable asthma in his breathless journey to ego mastery and timeless creativity.

    Full Text Available In this work, a possibility to develop a new zircon-based refractory coating for casting applications was investigated. Optimization of the coating composition with controlled rheological properties was attained by application of different coating components, particularly by application of a new suspension agent and by alteration of coating production procedure. Zircon powder with particle size of 25x10-6 m was used as filler. The zircon sample was investigated by means of the following methods: X-ray diffraction analysis, diffraction thermal analysis and polarized microscope. The shape and grain size were analyzed by means of the PC program package OZARIA 2.5. It was shown that application of this type of water-alcohol-based coating had a positive influence on surface quality, structural and mechanical properties of the castings of cast iron obtained by pouring into sand molds by means of the expandable patterns method (Lost Foam casting process.

    The Italian death rates and years of potential life lost (YPLL) for all causes and for 12 selected aggregations of causes are reported for 1979 and 1983, with the latter compared to United States data. Cancer is the leading cause of YPLL in Italy (23.8 per cent of total YPLL), followed by unintentional injuries (16.3 per cent) and heart disease (11.2 per cent). Rates of YPLL for all causes decreased 12.0 per cent from 1979 to 1983, the strongest declines in absolute terms being observed for prematurity and unintentional injuries, and in percentage decline for pneumonia and influenza, and infectious diseases; during the same period, YPLL for diabetes increased. The rates of YPLL are higher for males than for females (rate ratio = 1.9) especially for causes related to lifestyle factors. Premature mortality is lower in Italy than in the USA, because of the striking difference in mortality from injuries and heart diseases.

    The enhancement of efficiency is world-wide trend to survive under intense competition. In recent years, the efficiency in the power industry is also one of the important topics. In case of nuclear power plants(NPPs), the period and quality of maintenance is an especially important factor to increase efficiency as well as availability. Therefore, the accurate identification of the root causes for lost electric output is indispensable to decrease the period and to increase quality of maintenance. The diagnosis in NPPs is more difficult because the turbine cycle of NPPs uses saturated steam as working fluid. In this study, authors tried to develop an advisory system with the quantitative diagnosis model consisting of statistical regression analysis and Bayesian network for the support of nuclear turbine cycle diagnosis. The proposed advisory system includes the knowledge-base representing the normal or abnormal behavior of nuclear turbine cycle. Authors selected 34 boundary parameters that independently influence to electric output. Using the data collected from a turbine cycle simulation tool, the statistical correlation between a boundary parameter and electric output was analyzed. To give the belief, that is the degree of accuracy, of root causes under various uncertainty sources, belief module for the boundary parameters is developed on the basis of Bayesian network. In conclusion, this diagnosis module can give the impacts of the root causes and their uncertainty simultaneously, so we call it 'Lost MW calculator'. After the validation using simulated data and actual performance data, this module was installed in Younggwang NPP units 3 and 4 in Korea. (author)

    In the last decades, marine reserves have dramatically increased in number worldwide. Here I examined the potential of no-take marine reserves to reestablish lost predatory interactions and, in turn, cause community-wide changes in Mediterranean rocky reefs. Protected locations supported higher density and size of the most effective fish preying on sea urchins (the sea breams Diplodus sargus and D. vulgaris) than unprotected locations. Density of sea urchins (Paracentrotus lividus and Arbacia lixula) was lower at protected than at unprotected locations. Size structure of P. lividus was bimodal (a symptom of predation on medium-sized urchins) only at the protected locations. Coralline barrens were less extended at protected than at unprotected locations, whereas turf-forming and erect-branched algae showed an opposite pattern. Erect-unbranched and erect-calcified algae and conspicuous zoobenthic organisms did not show any pattern related to protection. Tethering experiments showed that predation impact on urchins was (1) higher at protected than at unprotected locations, (2) higher on P. lividus than on A. lixula, and (3) higher on medium-sized (2-3.5 cm test diameter) than large-sized (>3.5 cm) urchins. Sea urchins preyed on by fish in natural conditions were smaller at unprotected than at protected locations. The analysis of sea urchin remains found in Diplodus fish stomachs revealed that medium-sized P. lividus were the most frequently preyed upon urchins and that size range of consumed sea urchins expanded with increasing size of Diplodus fish. These results suggest that (1) depletion and size reduction of predatory fish caused by fishing alter patterns of predation on sea urchins, and that (2) fishing bans (e.g., within no-take marine reserves) may reestablish lost interactions among strongly interactive species in temperate rocky reefs with potential community-wide effects.

    2012-09-01

    Full Text Available A brain computer interface (BCI enables direct communication between a brain and a computer translating brain activity into computer commands using preprocessing, feature extraction and classification operations. Classification is crucial as it has a substantial effect on the BCI speed and bit rate. Recent developments of brain-computer interfaces (BCIs bring forward some challenging problems to the machine learning community, of which classification of time-varying electrophysiological signals is a crucial one. Constructing adaptive classifiers is a promising approach to deal with this problem. In this paper, we introduce adaptive classifiers for classify electroencephalogram (EEG signals. The adaptive classifier is brain emotional learning based adaptive classifier (BELBAC, which is based on emotional learning process. The main purpose of this research is to use a structural model based on the limbic system of mammalian brain, for decision making and control engineering applications. We have adopted a network model developed by Moren and Balkenius, as a computational model that mimics amygdala, orbitofrontal cortex, thalamus, sensory input cortex and generally, those parts of the brain thought responsible for processing emotions. The developed method was compared with other methods used for EEG signals classification (support vector machine (SVM and two different neural network types (MLP, PNN. The result analysis demonstrated an efficiency of the proposed approach.

    Full Text Available Much effort has gone into elucidating control of the body by the brain, less so the role of the body in controlling the brain. This essay develops the idea that the brain does a great deal of work in the service of behavior that is controlled by the body, a blue collar role compared to the white collar control exercised by the body. The argument that supports a blue collar role for the brain is also consistent with recent discoveries clarifying the white collar role of synergies across the body's tensegrity structure, and the evidence of critical phenomena in brain and behavior.

    A variety of imaging modalities are currently used to evaluate the brain. Prior to the 1970s, neurologic imaging involved radiographs, invasive procedures for spinal and carotid artery air and contrast injection, and painful patient manipulation. The brain was considered inaccessible to imaging and referred to as "the dark continent." Since then, advances in neuroradiology have moved the brain from being a dark continent to evaluation techniques that illuminate brain contents and pathology. These advances enable quick acquisition of images for prompt diagnosis and treatment. This article reviews anatomy, diagnostic principles, and clinical application of brain imaging beyond plain radiographs.

    Full Text Available Sensory substitution devices are providing new ways for improving or replacing sensory abilities that have been lost due to disease or injury, and at the same time offer unprecedented opportunities to address how the nervous system could lead to an augmentation of its capacities. In this work we have evaluated a color-blind subject using a new visual-to-auditory sensory substitution device (SSD device called Eyeborg, that allows colors to be perceived as sounds. We used a combination of neuroimaging techniques including Functional Magnetic Resonance Imaging (fMRI, Diffusion Tensor Imaging (DTI and proton Magnetic Resonance Spectroscopy (1H-MRS to study potential brain plasticity in this subject. Our results suggest that after 8 years of continuous use of this device there could be significant adaptive and compensatory changes within the brain. In particular, we found changes in functional neural patterns, structural connectivity and cortical topography at the visual and auditive cortex of the Eyeborg user in comparison with a control population. Although at the moment we cannot claim that the continuous use of the Eyeborg is the only reason for these findings, our results may shed further light on potential brain changes associated with the use of other SSDs. This could help to better understand how the brain adapts to several pathologies and uncover adaptive resources such as cross-modal representations. We expect that the precise understanding of these changes will have clear implications for rehabilitative training, device development and for more efficient programs for people with disabilities.

  12. Whither brain death?

    Science.gov (United States)

    Bernat, James L

    2014-01-01

    The publicity surrounding the recent McMath and Muñoz cases has rekindled public interest in brain death: the familiar term for human death determination by showing the irreversible cessation of clinical brain functions. The concept of brain death was developed decades ago to permit withdrawal of therapy in hopeless cases and to permit organ donation. It has become widely established medical practice, and laws permit it in all U.S. jurisdictions. Brain death has a biophilosophical justification as a standard for determining human death but remains poorly understood by the public and by health professionals. The current controversies over brain death are largely restricted to the academy, but some practitioners express ambivalence over whether brain death is equivalent to human death. Brain death remains an accepted and sound concept, but more work is necessary to establish its biophilosophical justification and to educate health professionals and the public.

    The biogeochemical features of the microelement distribution in the components of the ecosystem of the Lost City low-temperature field of the Mid-Atlantic Ridge are determined by the processes of serpentinization in ultrabasic rocks. In the Lost City biotope water, the concentration of trace metals (Fe, Mn, Zn, Cu, Cd, Ni, Cr, Pb, and As) is from n × 10 to 104 times higher than in the ocean water. The microelement content demonstrates a similar character of distribution in both types of calcite biominerals forming the carbonate matrix of the bivalve mussels Bathymodiolus and the scleractinian corals Anthozoa.

  14. Closing the Door to Lost Earnings Under the National Childhood Vaccine Injury Act of 1986.

    Science.gov (United States)

    Levin, Aaron

    2015-01-01

    After a wave of lawsuits against vaccine manufacturers hindered the profitability and production of life-saving vaccines, Congress enacted The National Childhood Vaccine Injury Act of 1986. The Act offers an incentive for individuals to get vaccinated in order to mitigate the population's exposure to disease, while encouraging the continued production of these serums by pharmaceutical companies. Although imperfect, the Vaccine Act fosters promise in filtering out frivolous claims and,provides a central route for due process to the individuals who suffer from a vaccine-related injury. By removing a potential state tort issue to the Federal Circuit, Congress created a reasonably justified avenue for the recovery of damages for injuries and adverse reactions to vaccines. However, this is not to say that the Act can't still be improved. Currently, the Act is silent on whether the death of a child from a vaccine-related injury, before a compensation decision is rendered, should bar the family from recovering for the child's lost earnings. Unless the victim demonstrates a stable source of income that they would have earned had their lives not been interrupted by the adverse reaction to the vaccine, the holding that a minor child may not recover for lost earnings is defensible. However, Congress should revise the statute to issue guidance to clarify its ambiguity. Under the current compensation regime, the standard is too arbitrary to decide that a child who dies before reaching the majority age of 18 has no earning potential. Any line Congress or the Supreme Court tries to draw will be arbitrary, but from an economic, policy, and legal perspective clarity and guidance can be offered to maintain greater flexibility through a case-by-case analysis and by applying the modern minimum wage in reference to the child's age. Independent from future earnings awards, Vaccine Act compensation should be amended to increase the cap on these damages to account for inflation since the

    To investigate the supplement of lost nerve cells in rats with traumatic brain injury by intrave-nous administration of allogenic bone marrow mesenchymal stem cells, this study established a Wistar rat model of traumatic brain injury by weight drop impact acceleration method and ad-ministered 3 × 106 rat bone marrow mesenchymal stem cells via the lateral tail vein. At 14 days after cell transplantation, bone marrow mesenchymal stem cells differentiated into neurons and astrocytes in injured rat cerebral cortex and rat neurological function was improved significant-ly. These findings suggest that intravenously administered bone marrow mesenchymal stem cells can promote nerve cell regeneration in injured cerebral cortex, which supplement the lost nerve cells.

  16. Brain size, sex, and the aging brain.

    2015-01-01

    This study was conducted to examine the statistical influence of brain size on cortical, subcortical, and cerebellar compartmental volumes. This brain size influence was especially studied to delineate interactions with Sex and Age. Here, we studied 856 healthy subjects of which 533 are classified as young and 323 as old. Using an automated segmentation procedure cortical (gray and white matter [GM and WM] including the corpus callosum), cerebellar (GM and WM), and subcortical (thalamus, putamen, pallidum, caudatus, hippocampus, amygdala, and accumbens) volumes were measured and subjected to statistical analyses. These analyses revealed that brain size and age exert substantial statistical influences on nearly all compartmental volumes. Analyzing the raw compartmental volumes replicated the frequently reported Sex differences in compartmental volumes with men showing larger volumes. However, when statistically controlling for brain size Sex differences and Sex × Age interactions practically disappear. Thus, brain size is more important than Sex in explaining interindividual differences in compartmental volumes. The influence of brain size is discussed in the context of an allometric scaling of the compartmental volumes.

    Genetic mechanisms underlying abnormal early neural development in toddlers with Autism Spectrum Disorder (ASD) remain uncertain due to the impossibility of direct brain gene expression measurement during critical periods of early development. Recent findings from a multi-tissue study demonstrated high expression of many of the same gene networks between blood and brain tissues, in particular with cell cycle functions. We explored relationships between blood gene expression and total brain volume (TBV) in 142 ASD and control male toddlers. In control toddlers, TBV variation significantly correlated with cell cycle and protein folding gene networks, potentially impacting neuron number and synapse development. In ASD toddlers, their correlations with brain size were lost as a result of considerable changes in network organization, while cell adhesion gene networks significantly correlated with TBV variation. Cell cycle networks detected in blood are highly preserved in the human brain and are upregulated during prenatal states of development. Overall, alterations were more pronounced in bigger brains. We identified 23 candidate genes for brain maldevelopment linked to 32 genes frequently mutated in ASD. The integrated network includes genes that are dysregulated in leukocyte and/or postmortem brain tissue of ASD subjects and belong to signaling pathways regulating cell cycle G1/S and G2/M phase transition. Finally, analyses of the CHD8 subnetwork and altered transcript levels from an independent study of CHD8 suppression further confirmed the central role of genes regulating neurogenesis and cell adhesion processes in ASD brain maldevelopment.

  18. On the lost portrait of Galileo by the Tuscan painter Santi di Tito

    Molaro, Paolo

    2016-12-01

    We study here the first established image of Galileo from the engraving made by Giuseppe Calendi at the end of the eighteenth century after a lost portrait of 1601 by Santi di Tito. We show that the engraving cannot be an exact copy, as it contains several inaccuracies which are unlikely to have been present in the original painting. A recent claim of the discovery of the painting by Santi di Tito is examined, and some reasons for suspecting it to be a forgery are outlined. As an alternative, we suggest a connection between the engraving and a portrait attributed to Tintoretto (which is currently in the collection of the Padua Civic Museum). The engraving and the Padua painting look quite different but can be traced to a common origin if we assume that Calendi added the half body, copied the painting onto copper plate directly, and adjusted the shading slightly. In this way, several features and details of the engraving find a plausible explanation. Finally, we note a remarkable similarity between the Padua portrait and a figure included in a Cologne painting by Rubens dating to about 1602-1604, which was suggested by Huemer to be Galileo.

  19. Optimization in Fuzzy Economic Order Quantity (FEOQ Model with Deteriorating Inventory and Units Lost

    2014-09-01

    Full Text Available Background: This model presents the effect of deteriorating items in fuzzy optimal instantaneous replenishment for finite planning horizon. Accounting for holding cost per unit per unit time and ordering cost per order have traditionally been the case of modeling inventory systems in fuzzy environment. These imprecise parameters defined on a bounded interval on the axis of real numbers and the physical characteristics of stocked items dictate the nature of inventory policies implemented to manage and control in the production system.   Methods: The modified fuzzy EOQ (FEOQ model is introduced, it assumes that a percentage of the on-hand inventory is wasted due to deterioration and considered as an enhancement to EOQ model to determine the optimal replenishment quantity so that the net profit is maximized. In theoretical analysis, the necessary and sufficient conditions of the existence and uniqueness of the optimal solutions are proved and further the concavity of the fuzzy net profit function is established. Computational algorithm using the software LINGO 13.0 version is developed to find the optimal solution.   Results and conclusions: The results of the numerical analysis enable decision-makers to quantify the effect of units lost due to deterioration on optimizing the fuzzy net profit for the retailer. Finally, sensitivity analyses of the optimal solution with respect the major parameters are also carried out. Furthermore fuzzy decision making is shown to be superior then crisp decision making in terms of profit maximization. 

  20. Evaluating postgraduate public health and biomedical training program outcomes: : lost opportunities and renewed interest.

    2013-03-01

    To identify recent studies in the scientific literature that evaluated structured postgraduate public health and biomedical training programs and reported career outcomes among individual trainees, a comprehensive search of several databases was conducted to identify published studies in English between January 1995 and January 2012. Studies of interest included those that evaluated career outcomes for trainees completing full-time public health or biomedical training programs of at least 12 months duration, with structured training offered on-site. Of the over 600 articles identified, only 13 met the inclusion criteria. Six studies evaluated US federal agency programs and six were of university-based programs. Seven programs were solely or predominantly of physicians, with only one consisting mainly of PhDs. Most studies used a cohort or cross-sectional design. The studies were mainly descriptive, with only four containing statistical data. Type of employment was the most common outcome measure (n = 12) and number of scientific publications (n = 6) was second. The lack of outcomes evaluation data from postgraduate public health and biomedical training programs in the published literature is a lost opportunity for understanding the career paths of trainees and the potential impact of training programs. Suggestions for increasing interest in conducting and reporting evaluation studies of these structured postgraduate training programs are provided.

    This paper estimates the health costs at Superfund sites for conditions associated with volatile organic compounds (VOCs) in drinking water. Health conditions were identified from published literature and registry information as occurring at excess rates in VOC-exposed populations. These health conditions were: (1) some categories of birth defects, (2) urinary tract disorders, (3) diabetes, (4) eczema and skin conditions, (5) anemia, (6) speech and hearing impairments in children under 10 years of age, and (7) stroke. Excess rates were used to estimate the excess number of cases occurring among the total population living within one-half mile of 258 Superfund sites. These sites had evidence of completed human exposure pathways for VOCs in drinking water. For each type of medical condition, an individual`s expected medical costs, long-term care costs, and lost work time due to illness or premature mortality were estimated. Costs were calculated to be approximately $330 million per year, in the absence of any remediation or public health intervention programs. The results indicate the general magnitude of the economic burden associated with a limited number of contaminants at a portion of all Superfund sites, thus suggesting that the burden would be greater than that estimated in this study if all contaminants at all Superfund sites could be taken into account.

    Hurricanes Ivan, Katrina, and Rita passed through the Gulf of Mexico during 2004 and 2005 and resulted in the largest number of destroyed and damaged offshore oil and gas structures in the history of Gulf operations. In the final official government assessment, a total of 126 platforms were destroyed and over 183 structures were identified as having extensive damage. Production associated with wells and structures that are not redeveloped are classified as lost. The purpose of this paper is to derive functional relations that describe the likely contribution the collection of destroyed assets would have made to future production in the Gulf of Mexico. We estimate that the total remaining reserves from the set of destroyed structures range in value between 1.3 and 4.5 billion depending on the assumptions employed. We summarize the impact of the storms on the Gulf of Mexico oil and gas infrastructure and discuss the main issues involved in redevelopment decision making. A meta-model analytic framework is applied to perform sensitivity analysis and to explore the interactions of assumptions on model output. A discussion of the limitations of the analysis is presented. (author)

  3. Anomalously high variation in postnatal development is ancestral for dinosaurs but lost in birds.

    Griffin, Christopher T; Nesbitt, Sterling J

    2016-12-20

    Compared with all other living reptiles, birds grow extremely fast and possess unusually low levels of intraspecific variation during postnatal development. It is now clear that birds inherited their high rates of growth from their dinosaurian ancestors, but the origin of the avian condition of low variation during development is poorly constrained. The most well-understood growth trajectories of later Mesozoic theropods (e.g., Tyrannosaurus, Allosaurus) show similarly low variation to birds, contrasting with higher variation in extant crocodylians. Here, we show that deep within Dinosauria, among the earliest-diverging dinosaurs, anomalously high intraspecific variation is widespread but then is lost in more derived theropods. This style of development is ancestral for dinosaurs and their closest relatives, and, surprisingly, this level of variation is far higher than in living crocodylians. Among early dinosaurs, this variation is widespread across Pangaea in the Triassic and Early Jurassic, and among early-diverging theropods (ceratosaurs), this variation is maintained for 165 million years to the end of the Cretaceous. Because the Late Triassic environment across Pangaea was volatile and heterogeneous, this variation may have contributed to the rise of dinosaurian dominance through the end of the Triassic Period.

  4. Preliminary juvenile Lost River and shortnose sucker investigations in Clear Lake, California--2011 pilot study summary

    Burdick, Summer M.; Rasmussen, Josh

    2012-01-01

    Poor recruitment appears to limit the recovery of Lost River and shortnose sucker populations in Clear Lake Reservoir, California, but the cause is unknown. Adult suckers migrate up Willow Creek and its tributaries to spawn in some years, but low flow in Willow Creek may inhibit spawning migrations in other years. It is unclear whether spawning is successful, larvae survive, or juveniles persist to adulthood. Environmental variables associated with successful spawning or young-of-year survival have not been identified and early life history for these populations is poorly understood. The U.S. Geological Survey in cooperation with the U.S. Fish and Wildlife Service and Ruby Pipeline L.L.C. Corporation (El Paso, Tex.) initiated a study in 2011 to better understand juvenile sucker life history in Clear Lake Reservoir, and to identify constraints in the early life history that may limit recruitment to the adult spawning populations. This is a report on the 2011 pilot study for this project.

  5. Aggression and guilt during mourning by parents who lost an infant.

    Science.gov (United States)

    Hasui, Chieko; Kitamura, Toshinori

    2004-01-01

    The authors conducted in-depth interviews with 38 mothers and fathers who had lost an infant. The focus of the interview was aggression and guilt during mourning work. The participants felt strong shame after separation. Phenomena such as strong irrational guilt, aggression, and hesitation toward others were similar to feelings typical of the paranoid-schizoid position. However, mourners did not lose their sense of reality, continued to do daily chores, and kept taking care of others. In this period, mourners were in disintegration, similar to individuals in the paranoid-schizoid position. Shame may be the feeling in the residue of the paranoid-schizoid position, through which they felt persecuted by others, their partner, relatives, and God. Their aggression was strong, but generally their aggression and impulses came to be used constructively and they progressed to integration. At the moment their children died, mourners fluctuated between disintegration and integration. After a certain interval, fluctuation subsided or integration predominated. In times of fluctuation, containers were very important for mourners to move toward integration. Participants reported changes in their lifestyle after the loss of a child. Mental health professionals should view aggressive impulses among such people during mourning not as an obstacle, but rather as a means to move toward integration. The authors speculate that a psychotherapist can serve as a container for mourners.

  6. Lost in Translation? Pussy Riot Solidary Activism and the danger of perpetuating North/Western Hegemonies

    Directory of Open Access Journals (Sweden)

    Katharina Wiedlack

    2014-12-01

    Full Text Available This article critically discusses solidarity actions in support of Pussy Riot within the global North/West, arguing that most solidarity projects within popular culture as well as within the queer-feminist counterculture are based on a lopsided interpretation of Pussy Riot as Russian version of Riot Grrrl feminists. This one-dimensional interpretation of the performance art group as Riot Grrrl-identities further leads to labelling their performance at the Christ the Saviour Cathedral as anti-religious. Within this framework the group’s negotiation of Orthodox religion within their song lyrics, performances as well as statements is ignored, supporting the binary construction of The North/West as progressive – tolerant and secular – and Russia as backward – dogmatic and fundamentalist religious. We attempt to complicate the view on Pussy Riot’s performances and reread them within the Russian context, highlighting several political statements that got lost in North/Western translations. The focus of the analysis concentrates on the ‘Punk Prayer, its mimicry of religious language and references to the leadership of the Russian Orthodox Church as well as the local public critical discourses.

  7. Quantifying lost information due to covariance matrix estimation in parameter inference

    CERN Document Server

    Sellentin, Elena

    2016-01-01

    Parameter inference with an estimated covariance matrix systematically loses information due to the remaining uncertainty of the covariance matrix. Here, we quantify this loss of precision and develop a framework to hypothetically restore it, which allows to judge how far away a given analysis is from the ideal case of a known covariance matrix. We point out that it is insufficient to estimate this loss by debiasing a Fisher matrix as previously done, due to a fundamental inequality that describes how biases arise in non-linear functions. We therefore develop direct estimators for parameter credibility contours and the figure of merit. We apply our results to DES Science Verification weak lensing data, detecting a 10% loss of information that increases their credibility contours. No significant loss of information is found for KiDS. For a Euclid-like survey, with about 10 nuisance parameters we find that 2900 simulations are sufficient to limit the systematically lost information to 1%, with an additional unc...

  8. The lost constellations a history of obsolete, extinct, or forgotten star lore

    Barentine, John C

    2016-01-01

    Casual stargazers are familiar with many classical figures and asterisms composed of bright stars (e.g., Orion and the Plough), but this book reveals not just the constellations of today but those of yesteryear. The history of the human identification of constellations among the stars is explored through the stories of some influential celestial cartographers whose works determined whether new inventions survived. The history of how the modern set of 88 constellations was defined by the professional astronomy community is recounted, explaining how the constellations described in the book became permanently “extinct.”  Dr. Barentine addresses why some figures were tried and discarded, and also directs observers to how those figures can still be picked out on a clear night if one knows where to look. These lost constellations are described in great detail using historical references, ennabling observers to rediscover them on their own surveys of the sky. Treatment of the obsolete constellations as ...

  9. Patient-reported outcomes (PRO) in ovarian cancer clinical trials-lost opportunities and lessons learned.

    Despite increased recognition of the value of including patient-reported outcomes (PROs) as important end points in phase III clinical trials, there has been a lack of pre-specified PRO hypotheses and shortcomings with the analyses and interpretation of PROs in many ovarian cancer trials. This paper discusses and provides examples of the so-called lost opportunities in ovarian cancer trials. These include: (i) no clear pre-specified PRO hypotheses; (ii) PRO end points not included; (iii) insensitive PRO end point selection; (iv) collection of poor-quality PRO data not suitable for analysis; (v) differences in PROs between treatment arms ignored; and (vi) poor reporting quality. We can learn from the past and with relatively little additional effort, improve the collection and interpretation of PRO data in future ovarian cancer trials. The importance of doing so is underpinned by recent initiatives to improve the standard and usefulness of PRO data in clinical trials. These include the Food and Drug Administration (FDA) Guidance for PROs to support labelling claims, the European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO MCBS), the International Society for Quality-of-Life Research PRO reporting guidance and the Consolidated Standards of Reporting Clinical Trials (CONSORT)-PRO-extension statement which includes a checklist of recommended items to include in PRO sections of trial protocols. Promoting the importance of hypothesis-driven PROs in ovarian cancer clinical trials will lead to improvements in the design of these trials and the interpretation of their results.

    We developed a lost alpha detection system to use in burning plasma experiments. The scintillators of Ag:ZnS and polycrystalline Ce:YAG were designed for a high-temperature environment, and the optical transmission line was designed to transmit from the scintillator to the port plug. The required optical components of lenses and mirrors were irradiated using the fission reactor with the initial result that there was no clear change after the irradiation with a neutron flux of 9.6×10(17) nm(-2)  s(-1) for 48 h. We propose a diagnostic of alpha particle loss, so-called alpha particle induced gamma ray spectroscopy. The initial laboratory test has been carried out by the use of the Ce doped Lu(2)SiO(5) scintillator detector and an Am-Be source to detect the 4.44 MeV high energy gamma ray due to the (9)Be(α,nγ)(12)C reaction.

  11. Anomalously high variation in postnatal development is ancestral for dinosaurs but lost in birds

    Griffin, Christopher T.; Nesbitt, Sterling J.

    2016-12-01

    Compared with all other living reptiles, birds grow extremely fast and possess unusually low levels of intraspecific variation during postnatal development. It is now clear that birds inherited their high rates of growth from their dinosaurian ancestors, but the origin of the avian condition of low variation during development is poorly constrained. The most well-understood growth trajectories of later Mesozoic theropods (e.g., Tyrannosaurus, Allosaurus) show similarly low variation to birds, contrasting with higher variation in extant crocodylians. Here, we show that deep within Dinosauria, among the earliest-diverging dinosaurs, anomalously high intraspecific variation is widespread but then is lost in more derived theropods. This style of development is ancestral for dinosaurs and their closest relatives, and, surprisingly, this level of variation is far higher than in living crocodylians. Among early dinosaurs, this variation is widespread across Pangaea in the Triassic and Early Jurassic, and among early-diverging theropods (ceratosaurs), this variation is maintained for 165 million years to the end of the Cretaceous. Because the Late Triassic environment across Pangaea was volatile and heterogeneous, this variation may have contributed to the rise of dinosaurian dominance through the end of the Triassic Period.

    Autism spectrum disorder diagnoses sometimes change due to misdiagnosis, maturation, or treatment. This study uses a probability-based national survey-the Survey of Pathways to Diagnosis and Services-to compare currently diagnosed (n = 1420) and previously diagnosed (n = 187) children aged 6-17 years based on retrospective parental reports of early concerns about their children's development, responses to those concerns by doctors and other healthcare providers, the type of provider who made the first autism spectrum disorder diagnosis, and the autism spectrum disorder subtype diagnoses received (if any). Propensity score matching was used to control for differences between the groups on children's current level of functioning and other current characteristics that may have been related to diagnosis loss. Approximately 13% of the children ever diagnosed with autism spectrum disorder were estimated to have lost the diagnosis, and parents of 74% of them believed it was changed due to new information. Previously diagnosed children were less likely to have parents with early concerns about verbal skills, nonverbal communication, learning, and unusual gestures or movements. They were also less likely to have been referred to and diagnosed by a specialist. Previously diagnosed children were less likely to have ever received a diagnosis of Asperger's disorder or autistic disorder.

    Highly migratory marine species can travel long distances and across entire ocean basins to reach foraging and breeding grounds, yet gaps persist in our knowledge of oceanic dispersal and habitat use. This is especially true for sea turtles, whose complex life history and lengthy pelagic stage present unique conservation challenges. Few studies have explored how these young at-sea turtles navigate their environment, but advancements in satellite technology and numerical models have shown that active and passive movements are used in relation to open ocean features. Here, we provide the first study, to the best of our knowledge, to simultaneously combine a high-resolution physical forcing ocean circulation model with long-term multi-year tracking data of young, trans-oceanic North Pacific loggerhead sea turtles during their 'lost years' at sea. From 2010 to 2014, we compare simulated trajectories of passive transport with empirical data of 1-3 year old turtles released off Japan (29.7-37.5 straight carapace length cm). After several years, the at-sea distribution of simulated current-driven trajectories significantly differed from that of the observed turtle tracks. These results underscore current theories on active dispersal by young oceanic-stage sea turtles and give further weight to hypotheses of juvenile foraging strategies for this species. Such information can also provide critical geographical information for spatially explicit conservation approaches to this endangered population.

  14. Quantifying lost information due to covariance matrix estimation in parameter inference

    Parameter inference with an estimated covariance matrix systematically loses information due to the remaining uncertainty of the covariance matrix. Here, we quantify this loss of precision and develop a framework to hypothetically restore it, which allows to judge how far away a given analysis is from the ideal case of a known covariance matrix. We point out that it is insufficient to estimate this loss by debiasing the Fisher matrix as previously done, due to a fundamental inequality that describes how biases arise in non-linear functions. We therefore develop direct estimators for parameter credibility contours and the figure of merit, finding that significantly fewer simulations than previously thought are sufficient to reach satisfactory precisions. We apply our results to DES Science Verification weak lensing data, detecting a 10 per cent loss of information that increases their credibility contours. No significant loss of information is found for KiDS. For a Euclid-like survey, with about 10 nuisance parameters we find that 2900 simulations are sufficient to limit the systematically lost information to 1 per cent, with an additional uncertainty of about 2 per cent. Without any nuisance parameters, 1900 simulations are sufficient to only lose 1 per cent of information. We further derive estimators for all quantities needed for forecasting with estimated covariance matrices. Our formalism allows to determine the sweetspot between running sophisticated simulations to reduce the number of nuisance parameters, and running as many fast simulations as possible.

  15. Effects of ambient water quality on the endangered Lost River sucker in Upper Klamath Lake, Oregon

    Martin, B.A.; Saiki, M.K.

    1999-01-01

    Populations of the Lost River sucker Deltistes luxatus have declined so precipitously in the Upper Klamath Basin of Oregon and California that this fish was recently listed for federal protection as an endangered species. Although Upper Klamath Lake is a major refuge for this species, fish in the lake occasionally experience mass mortalities during summer and early fall. This field study was implemented to determine if fish mortalities resulted from degraded water quality conditions associated with seasonal blooms of phytoplankton, especially Aphanizomenon flos-aquae. Our results indicated that fish mortality did not always increase as water temperature, pH, and un-ionized ammonia concentration increased in Upper Klamath Lake. Little or no mortality occurred when these water quality variables attained their maximum values. On the other hand, an inverse relation existed between fish mortality and dissolved oxygen concentration. High mortality (>90%) occurred whenever dissolved oxygen concentrations decreased to 1.05 mg/L, whereas mortality was usually low (< 10%) when dissolved oxygen concentrations equaled or exceeded 1.58 mg/L. Stepwise logistic regression also indicated that the minimum concentration of dissolved oxygen measured was the single most important determinant of fish mortality.

  16. Milton’s Pro-Feminist Presentation of Eve in Paradise Lost

    Abdullah F. Al-Badarneh

    2014-07-01

    Full Text Available This paper absolves John Milton from any critical and feminist accusation of being anti-feminist in Paradise Lost. Such defense of Milton is based on the close reading and analysis of the passages that focus on Adam and Eve in the text. This study highlights Milton’s modern view of women as independent, free, and responsible. It also presents his iconoclasm in representing women as leaders and initiative takers when decision is to be taken. This study shows Milton reversing traditional gender roles through the relationship of Adam and Eve. In addition, one can find a modern emphasis on the principles of equality, democracy, dialogue, freedom, and free will available in the poem and designed in a way that serves Eve’s rights in comparison with Adam’s. Therefore, my voice in defending Milton joins the cohort of critics who believe of Milton’s wide perspective of pro-feminism and not a person of misogyny. Keywords: feminism, hierarchy, equality, partnership, misogyny, binary opposition

  17. Women's perspectives on public policy in India: a half-century of incomplete or lost agenda?

    2000-01-01

    52 years is not a small period for initiating progress. The promises enshrined in the Indian Constitution and the vision of women's full emancipation advanced during the nationalist struggle have alas not merely receded, but there is every danger that the lost momentum may not be made up unless once again the authors gear ourselves to intervene more forcefully in the polity and public policy. What we find despite tall pronouncements and a great deal of rhetoric and sentiment, is that the reality of public policy that emerges is full of ambiguities, ambivalences and contradictions, often taking away with the left hand what the right hand gives. Women's recommendations towards a radical movement for promoting gender equality in free India got jettisoned. The cost to women of this neglect is documented by plenty of data. In spheres such as employment, education, population, health, family laws, environment, and criminal justice, the response of the state has often been either detrimental to women or merely helped maintain the status quo. In many spheres, while women's interventions have been substantial, these were like a finger in the dyke, unable to reverse major policy directions.

  18. The estimated magnitude of AIDS in Brazil: a delay correction applied to cases with lost dates

    Barbosa Maria Tereza S.

    2002-01-01

    Full Text Available The number of HIV-infected people is an important measure of the magnitude of the AIDS epidemic in Brazil and allows for comparison with epidemic patterns in other countries. This quantity can be estimated from the number of reported AIDS cases, which in turn needs to be corrected for the distribution of reporting delays and under-recording of cases. These distributions are unknown and must also be estimated from the recorded dates, which were missed to the Brazilian National AIDS registry. This paper estimates the number of AIDS cases diagnosed by imputing the lost information based on an estimate of the pattern in registration delay until 1996. We first fitted a non-stationary bivariate Poisson regression model to estimate the pattern in reporting delay. In the subsequent steps these models were applied to impute new data, thus replacing the missing information, and to estimate the magnitude of the AIDS epidemic in the country. Model estimates ranged from 36,000 to 50,000 AIDS cases diagnosed in Brazil and still unreported. Therefore, the epidemic was 20 to 30% greater than known from the available information as of February 1999. To be useful to health policy-makers, the surveillance system based on officially reported AIDS cases must be continuously improved.

    Effects of vacuum, pouring temperature and pattern thickness on the heat transfer of magnesium alloy lost foam casting(LFC) process were explored. The results indicate that without vacuum a positive thermal gradient from the gate to the end of the casting was formed immediately after the mold filling. The average temperature of the casting, the temperature gradient and solidification times increase significantly with pouring temperature and pattern thickness. Vacuum plays a quite different role in the heat transfer during mould filling and solidification periods: it significantly increases the cooling rate of the filling melt, but decreases the cooling rate of the casting during solidification period. The temperature of the liquid metal drops sharply and varies greatly with no apparent mode in the casting after the mold filling. The amplitude of temperature fluctuations in the casting increases with vacuum, pouring temperature and pattern thickness. The average temperature increases with pouring temperature and pattern thickness, but less rapidly than that without vacuum. The effect of vacuum on the solidification times of castings is found to depend on pouring temperature, vacuum makes solidification times increase greatly at high pouring temperature, while decreases slightly at low pouring temperature.

  20. Influence of mechanical vibration on the solidification of a lost foam cast 356 alloy

    2010-02-01

    Full Text Available Mechanical vibration was applied to the solidification of a lost foam cast (LFC 356 aluminum alloy. Effects of mechanical vibration, with different peak acceleration, on the size and morphology of α-Al phase, and also on the mechanical properties of the castings were studied. Results indicated that α-Al dendrites gradually grow into equiaxed grains as the peak acceleration of vibration is increased. When the peak acceleration is between about 1 to 4 g,α-Al phase distribution is uniform and is refined obviously. α-Al dendrites are reduced and the mechanical properties of the castings are improved significantly when compared to those of the castings that are produced without vibration. However, when the peak acceleration is higher than 4 g, strong vibration will lead to defects formation, such as sand adhesion, while the amount and size of pores will be increased. And due to theturbulent flow that caused by strong vibration, the chance of forming large pores in the matrix has been increased significantly. The increase in defects will result in the deterioration of mechanical properties.

    The microstructure and mechanical properties of AZ91 alloy prepared by lost foam casting(LFC) and various heat treatments have been investigated.The microstructure of the AZ91 alloy via LFC consists of dominant α-Mg and β-Mg17Al12 as well as a new phase Al32 Mn25 with size of about 5-50 μm,which has not been detected in AZ91 alloy prepared by other casting processes.The tests demonstrate that the as-cast mechanical properties are higher than those of sand gravity casting because of chilling and cushioning effect of foam pattern during the mould filling.The solution kinetics and the aging processes at different temperatures were also investigated by hardness and electrical resistivity measurements.The kinetics of aging are faster at the high temperature due to enhanced diffusion of atoms in the matrix,so the hardness peak at 380 ℃ occurs after 10 h;while at the lower aging temperature(150 ℃),the peak is not reached in the time(24 h) considered.

    Full Text Available By using ICP spectroscopy, energy dispersive spectroscopy (EDS analysis, X-ray diffraction, SEM and microscope analysis, the effects of Mn on the structure of B319 aluminum alloy are studied. The results show that without addition of Mn, there are coral-like Al2Cu phase and needle like Al5FeSi phase in the structure of casting with lost foam casting (LFC. Precipitation of Al2Cu can take plasce along the long sides of the Al5FeSi needles. Under the rapid cooling rates, such as ones in metallic mold, the Fe phase appears in the form of Chinese script α-Fe. With the addition of Mn, there are Chinese script α-Fe phases (Al15(Mn, Fe3Si2 in the structure of LFC casting. When Fe/Mn≦1.5, the needle-like β-Fe phases transform to Chinese script α-Fe completely. With the decrease of Fe/Mn ratio, the tensile strength and elongation increase, especially the elongation increases greatly. When Fe/Mn ratio decreases from 2.5 to1, the elongation ncreases from 1.2 to 1.9 % by 58 %.

    2016-06-01

    The nature of the liquid metal-pattern interface during mold filling in the Lost Foam casting of aluminum alloys was investigated using real-time X-ray radiography for both normal expanded polystyrene, and brominated polystyrene foam patterns. Filling the pattern under the action of gravity from above or below had little effect on properties, both cases resulting in a large scatter of tensile strength values, (quantified by their Weibull Modulus). Countergravity filling at different velocities demonstrated that the least scatter of tensile strength values (highest Weibull Modulus) was associated with the slowest filling, when a planar liquid metal-pattern interface occurred. Real-time X-ray radiography showed that the advancing liquid metal front became unstable above a certain critical velocity, leading to the entrainment of the degrading pattern material and associated defects. It has been suggested that the transition of the advancing liquid metal-pattern interface into an unstable regime may be a result of Saffman-Taylor Instability.

    The SIEV X was a tiny fishing vessel traveling from Indonesia to Australia in 2001, carrying around four hundred people seeking asylum after fleeing from the warfare and persecution predominantly in Iraq and Afghanistan. Many were women and children trying to enter Australia to join fathers and husbands already granted refugee status but not allowed to bring in family members because of new Australian laws on "Temporary Protection Visas". Of these, 353 drowned when the boat sank in international waters. The conservative Australian government denied responsibility, using the event in an election campaign to play on fears about illegal entry and border defense in the Islamophobic climate in the aftermath of 9/11. Yet many everyday Australians eventually became involved in a collaborative design process to create a memorial to those asylum seekers. This article discusses the debates around memorials for those lost at sea, and particularly for those who might be portrayed as enemies or "illegal immigrants" whose coming threatens national borders. It identifies the conditions under which the campaign to commemorate those who died on the SIEV X moved from being a minority interest to become a cause so widely supported by Australians across the country that the memorial was eventually erected in the heart of the national capital.

  5. Brain iron homeostasis.

    Science.gov (United States)

    Moos, Torben

    2002-11-01

    Iron is essential for virtually all types of cells and organisms. The significance of the iron for brain function is reflected by the presence of receptors for transferrin on brain capillary endothelial cells. The transport of iron into the brain from the circulation is regulated so that the extraction of iron by brain capillary endothelial cells is low in iron-replete conditions and the reverse when the iron need of the brain is high as in conditions with iron deficiency and during development of the brain. Whereas there is good agreement that iron is taken up by means of receptor-mediated uptake of iron-transferrin at the brain barriers, there are contradictory views on how iron is transported further on from the brain barriers and into the brain extracellular space. The prevailing hypothesis for transport of iron across the BBB suggests a mechanism that involves detachment of iron from transferrin within barrier cells followed by recycling of apo-transferrin to blood plasma and release of iron as non-transferrin-bound iron into the brain interstitium from where the iron is taken up by neurons and glial cells. Another hypothesis claims that iron-transferrin is transported into the brain by means of transcytosis through the BBB. This thesis deals with the topic "brain iron homeostasis" defined as the attempts to maintain constant concentrations of iron in the brain internal environment via regulation of iron transport through brain barriers, cellular iron uptake by neurons and glia, and export of iron from brain to blood. The first part deals with transport of iron-transferrin complexes from blood to brain either by transport across the brain barriers or by uptake and retrograde axonal transport in motor neurons projecting beyond the blood-brain barrier. The transport of iron and transport into the brain was examined using radiolabeled iron-transferrin. Intravenous injection of [59Fe-125]transferrin led to an almost two-fold higher accumulation of 59Fe than of

    2006-12-01

    A true story about an encounter between LTER scientists and a young Weddell seal in the Dry Valleys of Antarctica has inspired a new children's book, The Lost Seal. Written by Diane McKnight, professor of environmental engineering at the University of Colorado and fellow of the Institute of Arctic and Alpine Research (INSTAAR), the book is an engaging introduction to Antarctica and the Dry Valleys. McKnight tells the story of the seal in the context of the harsh Dry Valleys environment and the LTER scientific work taking place there. The book includes information about hydrology, limnology, and microbial ecology. Artwork by professional illustrator Dorothy Emerling connects young readers with the environment and wildlife of Antarctica, while artwork from children in Australia, England, New Zealand, and the United States emphasizes the international nature of interest in the Antarctic. The Lost Seal has been published in time for the International Polar Year and is the second book in the NSF-supported LTER children's book series. The Lost Seal is at the center of many outreach activities: classroom activities in four countries; a colorful children's book distributed to schools and sold in national parks; a teacher's edition of the book; curriculum development in Boulder, Colorado schools; an educational web site (www.mcmlter.org/lostseal); and workshops for scientists on how to create scientific children's literature. This session will describe the various outreach activities and show how lessons learned from publication of The Lost Seal might apply to other IPY outreach efforts.

    Jirsa, Viktor K

    2007-01-01

    Our contemporary understanding of brain function is deeply rooted in the ideas of the nonlinear dynamics of distributed networks. Cognition and motor coordination seem to arise from the interactions of local neuronal networks, which themselves are connected in large scales across the entire brain. The spatial architectures between various scales inevitably influence the dynamics of the brain and thereby its function. But how can we integrate brain connectivity amongst these structural and functional domains? Our Handbook provides an account of the current knowledge on the measurement, analysis and theory of the anatomical and functional connectivity of the brain. All contributors are leading experts in various fields concerning structural and functional brain connectivity. In the first part of the Handbook, the chapters focus on an introduction and discussion of the principles underlying connected neural systems. The second part introduces the currently available non-invasive technologies for measuring struct...

    BrainGain is a common trend within the last ten years in Europe and all-over the world. Managers, key players and scientists are allowed to choose wherever they want to work in the world. As there is a lack of qualified individuals for companies and universities, BrainGain has become a necessity, and mostly - the higher educated individuals are moving away according to a better offer elsewhere in the world. Therefore, a lot of expats are moving around with their families. Many times, the lack of integration at the current place, country or city, is the critical success factor for staying or leaving. Furthermore, if the family does not feel happy in the current location, then the manager or scientist will move away or return home and the investment will be lost. Moreover, many students have received a good education in a state university, however afterwards they have not secured a satisfactory job in the country where they have studied, therefore they are moving away to utilise their know-how. Measures to retain the know-how include a common placement and a welcome-culture in the country, and also exchanges on an international level.

    International audience; Our digestive tract has an autonomous functioning but also has a bidirectional relation with our brain known as brain-gut interactions. This communication is mediated by the autonomous nervous system, i.e., the sympathetic and parasympathetic nervous systems, with a mixed afferent and efferent component, and the circumventricular organs located outside the blood-brain barrier. The vagus nerve, known as the principal component of the parasympathetic nervous system, is a...

    Subjectivity, intentionality, self-awareness and will are major components of consciousness in human beings. Changes in consciousness and its content following different brain processes and malfunction have long been studied. Cognitive sciences assume that brain activities have an infrastructure, but there is also evidence that consciousness itself may change this infrastructure. The two-way influence between brain and consciousness has been at the center of philosophy and less so, of science. This so-called bottom-up and top-down interrelationship is controversial and is the subject of our article. We would like to ask: how does it happen that consciousness may provoke structural changes in the brain? The living brain means continuous changes at the synaptic level with every new experience, with every new process of learning, memorizing or mastering new and existing skills. Synapses are generated and dissolved, while others are preserved, in an ever-changing process of so-called neuroplasticity. Ongoing processes of synaptic reinforcements and decay occur during wakefulness when consciousness is present, but also during sleep when it is mostly absent. We suggest that consciousness influences brain neuroplasticity both during wakefulness as well as sleep in a top-down way. This means that consciousness really activates synaptic flow and changes brain structures and functional organization. The dynamic impact of consciousness on brain never stops despite the relative stationary structure of the brain. Such a process can be a target for medical intervention, e.g., by cognitive training.

    Jean Dominique Bauby, former editor of Elle, suffered a stroke to his brain stem that left him with locked-in syndrome. Subsequently, through blinking his left eye, he writes his memoir of this experience, The Diving Bell and the Butterfly. This paper explores the meaning of embodiment, especially as one's body bears upon one's personal identity. It explores the various challenges and threats to selfhood that result from Bauby's experience and recounts how Bauby rises to the challenge through his memory and imagination.

    Approximately two out of three persons affected with Alzheimer's disease are women. Estrogen is known to have positive effects on the levels of brain-derived mediators and circulation. Along with menopause, decreasing female sex hormone levels have been assumed to promote the development of memory disorders. It is possible that timing of the start of hormone replacement therapy exactly to the menopause could provide the best benefit in respect of memory and information processing. Prevention and treatment of risk factors of cardiovascular diseases along with regular exercise and a healthy diet are more important than hormone therapy in the prevention of memory disorders.

  5. Reorganization of the injured brain: Implications for studies of the neural substrate of cognition

    2011-01-01

    Full Text Available In the search for a neural substrate of cognitive processes, a frequently utilized method is the scrutiny of posttraumatic symptoms exhibited by individuals suffering focal injury to the brain. For instance, the presence or absence of conscious awareness within a particular domain may, combined with knowledge of which regions of the brain have been injured, provide important data in the search for neural correlates of consciousness. Like all studies addressing the consequences of brain injury, however, such research has to face the fact that in most cases, posttraumatic impairments are accompanied by a functional recovery during which symptoms are reduced or eliminated. The apparent contradiction between localization and recovery, respectively, of functions constitutes a problem to almost all aspects of cognitive neuroscience. Several lines of investigation indicate that although the brain remains highly plastic throughout life, the posttraumatic plasticity does not recreate a copy of the neural mechanisms lost to injury. Instead, the uninjured parts of the brain are functionally reorganized in a manner which – in spite of not recreating the basic information processing lost to injury – is able to allow a more or less complete return of the surface phenomena (including manifestations of consciousness originally impaired by the trauma. A novel model (the REF-model of these processes is presented – and some of its implications discussed relative to studies of the neural substrates of cognition and consciousness.

  6. I am many: the reconstruction of self following acquired brain injury.

    Gelech, Jan M; Desjardins, Michel

    2011-01-01

    In this article we examine the construction of self following acquired brain injury from an experience-centered perspective. Life history and semistructured interview transcripts collected from four brain injury survivors were analyzed using thematic, syntactic, and deep structure analysis. Though notions of the "lost" or "shattered" self have dominated discussions of personhood in the acquired brain injury literature, we argue that this perspective is a crude representation of the postinjury experience of self, and that aspects of stability, recovery, transcendence, and moral growth are also involved in this process. We highlight the intersubjective nature of the self, and present the processes of delegitimation, invalidation, negotiation, and resistance as crucial aspects of the postinjury construction of personhood. We explore the implications of this complex process of construction of self for grief and bereavement theories, clinical practice, and professional discourse in the area of acquired brain injury.

    Ultramafic rocks formed in the Earth's mantle and uplifted into the crust represent an immense but poorly described reservoir of carbon. The biological availability of this rock-hosted carbon reservoir is unknown, but the set of geochemical reactions known as serpentinization can mobilize carbon from the subsurface and trigger the growth of dense microbial communities. Serpentinite-hosted ecosystems such as the chimney biofilms of the Lost City hydrothermal field can support dense populations of bacteria and archaea fueled by the copious quantities of H2 and methane (CH4) released by serpentinization (1-5). The metabolic pathways involved, however, remain unknown, and conventional interpretations of genomic and experimental data are complicated by the unusual carbon speciation in these environments. Carbon dioxide is scarce due to the highly reducing, high pH conditions. Instead, the predominant forms of carbon are CH4 and formate (5). Despite its natural abundance, however, direct evidence for CH4-derived biomass is lacking (1,4,5), and the role of formate is potentially significant but largely unexplored (1,5). To gain a more generalized perspective of carbon cycling in serpentinite-hosted ecosystems, we have recently investigated fluids and rocks collected from serpentinizing ophiolites in California, Canada, and Italy. Our results point to potentially H2-utilizing, autotrophic Betaproteobacteria thriving in shallow, oxic-anoxic transition zones and anaerobic Clostridia inhabiting anoxic, subsurface zones (1,6). The carbon sources utilized by the Clostridia are unknown, but preliminary metagenomic evidence is consistent with a fermentation-style metabolic strategy that may be conducive to an oxidant-limited, subsurface environment. Curiously, despite the abundance of H2 and CH4 in these continental springs, none of the geochemical, genomic, or experimental results obtained thus far contain any evidence for biological methanogenesis (1,6). This is in stark

    Previous studies have mainly used mortality or morbidity as the health outcome to examine the air pollution-health association. Little evidence is available on relationships between air pollutants and years of life lost (YLL). We aimed to estimate the YLL from cardiovascular mortality due to air pollution. Daily data on weather and air pollutants and individual data of all registered deaths for years 2004-2007 were obtained in Guangzhou, China. The generalized additive model was used to assess the YLL associated with 10μg/m(3) increases in NO2, SO2 and PM10. We found that the mean daily YLL was 248, 87.5 and 73.7 for deaths from cardiovascular disease (CVD), stroke and ischemic heart disease (IHD), respectively. A significant linear correlation was observed between air pollution and YLL due to cardiovascular disease. The effects of air pollutants on YLL were immediate and lasted for two days. A 10μg/m(3) increase above the corresponding threshold of 55.6μg/m(3), 40.4μg/m(3) and 0μg/m(3) in NO2, PM10 and SO2 was related to YLL increase of 1.8 (95% CI: 0.8-2.9), 2.8 (1.7-3.8) and 2.6 (1.2-4.0) years at lag 0-1days for CVD, respectively. The estimates of YLL associated with NO2 and PM10 were higher in men than women. The air pollutants-related YLL was higher among young people and those with low education level, compared to the elderly and those with high education level, respectively. These findings confirmed YLL provides a complementary strategy for assessing the health effect of air pollution. This study underscores the necessity of the reduction of air pollution benefiting public health.

  9. Direct evidence of swimming demonstrates active dispersal in the sea turtle "lost years".

    2015-05-04

    Although oceanic dispersal in larval and juvenile marine animals is widely studied, the relative contributions of swimming behavior and ocean currents to movements and distribution are poorly understood [1-4]. The sea turtle "lost years" [5] (often referred to as the surface-pelagic [6] or oceanic [7] stage) are a classic example. Upon hatching, young turtles migrate offshore and are rarely observed until they return to coastal waters as larger juveniles [5]. Sightings of small turtles downcurrent of nesting beaches and in association with drifting organisms (e.g., Sargassum algae) led to this stage being described as a "passive migration" during which turtles' movements are dictated by ocean currents [5-10]. However, laboratory and modeling studies suggest that dispersal trajectories might also be shaped by oriented swimming [11-15]. Here, we use an experimental approach designed to directly test the passive-migration hypothesis by deploying pairs of surface drifters alongside small green (Chelonia mydas) and Kemp's ridley (Lepidochelys kempii) wild-caught turtles, tracking their movements via satellite telemetry. We conclusively demonstrate that these turtles do not behave as passive drifters. In nearly all cases, drifter trajectories were uncharacteristic of turtle trajectories. Species-specific and location-dependent oriented swimming behavior, inferred by subtracting track velocity from modeled ocean velocity, contributed substantially to individual movement and distribution. These findings highlight the importance of in situ observations for depicting the dispersal of weakly swimming animals. Such observations, paired with information on the mechanisms of orientation, will likely allow for more accurate predictions of the ecological and evolutionary processes shaped by animal movement.

    The economic recovery of Newfoundland as a result of success in the Hibernia oilfield off the coast of Newfoundland is discussed. Oil production and the transport of oil from the Hibernia to the mainland by rugged double-hulled tankers that are about five times bigger than any other ship in Canada in terms of carrying capacity is a welcome event, considering that the seal hunt and the fishing industry that formerly provided sustenance to the people of Newfoundland have died as a result of world-wide pressure by animal rights groups, and indiscriminate overfishing. Transport of the crude oil from the Hibernia field is provided by Canship Ugland, a St. John's-based firm which now operates a fleet of three tankers. Each of the three vessels are capable of carrying 850,000 barrels of oil, or more than four times Hibernia's daily production. The 'Vinland' the latest of the three tankers to be commissioned, was built in South Korea, is 272 metres long and 46 metres wide. The ship is expected to carry oil from the rig 315 kms offshore to the Newfoundland Terminal at Whiffen Head, where the oil is picked up by smaller vessels. The 'Vinland' is equipped with the dynamic positioning feature which lets the ship maintain its maneuverability and position even if half her power is lost. The company employs people from all over the province and puts millions of dollars annually into the Newfoundland economy. 1 photo.

    1998-09-21

    The development of the sperm whale brain (Physeter macrocephalus) was investigated in 12 embryos and early fetuses to obtain a better understanding of the morphological and physiological adaptations in this most exotic cetacean concerning locomotion, deep diving, and orientation. In male adult sperm whales, the average absolute brain mass and the relative size of the telencephalic hemisphere are the largest within the mammalia, whereas the ratio of the brain mass to the total body mass is one of the smallest. In the early sperm whale fetus, the rostral part of the olfactory system (olfactory nerves and bulbs) is lost, whereas the nervus terminalis seems to persist. Several components of the limbic system show signs of regression (hippocampus, fornix, mamillary body). In contrast, some components of the auditory system (trapezoid body, inferior colliculus) show marked enlargement in the early fetal period, thereby reflecting their dominant position in the adult. The cerebellum and pons grow slower than in most smaller toothed whales. The pyramidal tract develops poorly (reduction of the limbs), whereas marked growth of the striatum and inferior olive may be related to the animal's locomotion via trunk and tail. In the early fetal period, the trigeminal, vestibulocochlear, and facial nerves are the dominant cranial nerves (besides the vagus nerve). Whereas the number of axons in the vestibulocochlear nerve is high in adult, toothed whales and their diameters are considerable, the trigeminal nerve of the sperm whale may be the thickest of all cranial nerves and has the largest number of axons (innervation of the huge forehead region). A similar situation seems to exist for the facial nerve: It innervates the blowhole musculature that surrounds the very large spermaceti organ and melon (generation and emission of sonar clicks).

    Disseminated candidiasis primarily targets the kidneys and brain in mice and humans. Damage to these critical organs leads to the high mortality associated with such infections, and invasion across the blood-brain barrier can result in fungal meningoencephalitis. Candida albicans can penetrate a brain endothelial cell barrier in vitro through transcellular migration, but this mechanism has not been confirmed in vivo. MRI using the extracellular vascular contrast agent gadolinium diethylenetriaminepentaacetic acid demonstrated that integrity of the blood-brain barrier is lost during C. albicans invasion. Intravital two-photon laser scanning microscopy was used to provide the first real-time demonstration of C. albicans colonizing the living brain, where both yeast and filamentous forms of the pathogen were found. Furthermore, we adapted a previously described method utilizing MRI to monitor inflammatory cell recruitment into infected tissues in mice. Macrophages and other phagocytes were visualized in kidney and brain by the administration of ultrasmall iron oxide particles. In addition to obtaining new insights into the passage of C. albicans across the brain microvasculature, these imaging methods provide useful tools to study further the pathogenesis of C. albicans infections, to define the roles of Candida virulence genes in kidney versus brain infection and to assess new therapeutic measures for drug development.

    Full Text Available Importance: With increasing number of persons living with Human Immunodeficiency Virus (HIV in major cities there is a need to have a comprehensive strategy to reduce the number of drop outs from the anti-retroviral (ART therapy. This can be done effectively only when we study the reasons why patients are lost to follow up. This study has brought to light novel causes of non-adherence to ART, like migration, discordance and resort to alternative therapies. DESIGN: This is a qualitative study conducted at ART Center, Byramjee Jeejeebhoy Medical College (BJMC and Sassoon General Hospital (SGH, Pune, a tertiary referral center in India. We included all those patients who were initiated antiretroviral therapy and lost to follow-up (LFU any time during the entire month after three months during which the appointment was scheduled. All these patients were interviewed during restart of ART, in ART center, BJMC and SGH. MAIN OUTCOMES AND MEASURES: All socio-demographic and clinical factors associated with antiretroviral therapy adherence. RESULTS: Out of a total 51patients lost to follow-up, patients above thirty five years of age and male sex were associated with a higher chance of being lost to LFU. Illiteracy rate was high in age group above 35 years (64.1% and in females. Male drivers were lost to follow-up at a greater extent [14(24.75%]. Out of 24(47.06% married patients, 12(50% male patients were sero-discordant. The chance of defaulting from therapy was high in the first three months and one year later from the initiation of therapy. Migration led to drop out of 13(25.49% patients. Other important factors leading to loss to follow up were: death in family, side effects of drugs and family disturbance. Alcoholism was the cause in 23(45.10% male patients. CONCLUSION AND RELEVANCE: Migration, illiteracy, alcoholism, discordant couples, death in family, low socio-economic status, resorting to alternative therapies were the prominent factors which

    Jordan M. Nechvatal

    2013-02-01

    Full Text Available One of the earliest and most consistent findings in behavioral neuroscience research is that learning changes the brain. Here we consider how learning as an aspect of coping in the context of stress exposure induces neuroadaptations that enhance emotion regulation and resilience. A systematic review of the literature identified 15 brain imaging studies in which humans with specific phobias or posttraumatic stress disorder were randomized to stress exposure therapies that diminished subsequent indications of anxiety. Most of these studies focused on functional changes in the amygdala and anterior corticolimbic brain circuits that control cognitive, motivational, and emotional aspects of physiology and behavior. Corresponding structural brain changes and the timing, frequency, and duration of stress exposure required to modify brain functions remain to be elucidated in future research. These studies will advance our understanding of coping as a learning process and provide mechanistic insights for the development of new interventions that promote stress coping skills.

    Full Text Available Brain Fingerprinting is a new computer-based technology to identify the perpetrator of a crime accurately and scientifically by measuring brain-wave responses to crime-relevant words or pictures presented on a computer screen. Brain Fingerprinting has proven 100% accurate in over 120 tests, including tests on FBI agents, tests for a US intelligence agency and for the US Navy, and tests on real-life situations including felony crimes. Brain fingerprinting is based on finding that the brain generates a unique brain wave pattern when a person encounters a familiar stimulus Use of functional magnetic resonance imaging in lie detection derives from studies suggesting that persons asked to lie show different patterns of brain activity than they do when being truthful. Issues related to the use of such evidence in courts are discussed. The author concludes that neither approach is currently supported by enough data regarding its accuracy in detecting deception to warrant use in court. In the field of criminology, a new lie detector has been developed in the United States of America. This is called “brain fingerprinting”. This invention is supposed to be the best lie detector available as on date and is said to detect even smooth criminals who pass the polygraph test (the conventional lie detector test with ease. The new method employs brain waves, which are useful in detecting whether the person subjected to the test, remembers finer details of the crime. Even if the person willingly suppresses the necessary information, the brain wave is sure to trap him, according to the experts, who are very excited about the new kid on the block.

    2009-02-01

    Full Text Available Background & objectives: During 2006, chikungunya emerged as a major ever known epidemic in India. Disability adjusted life years (DALY is an appropriate summary measure of population health to express epidemiological burden of diseases. We estimated the burden due to suspected chikungunya using DALYs for the first time and compared between the states and also with the burden due to other vector-borne diseases in India. The economic burden was also assessed in terms of productivity loss.Methods: Data on the reported cases of fever/suspected cases of chikungunya from different states during 2006 in India were used. Years lived with disability (YLD were calculated for non-fatal cases to estimate DALY. Since the disability weight for chikungunya is not available, the weights available for rheumatic arthritis, comparable to the disease outcome of chikungunya were used for the estimation. The burden was estimated for both acute and chronic cases. It is considered that about 11.5% of cases were reported to have extended morbidity with persisting arthralgia. For acute disease, the average duration of illness was considered to be nine days and for chronic cases it was six months on an average. The productivity loss due to income foregone by the working class was calculated using minimum official wage.Results: National burden of chikungunya was estimated to be 25,588 DALYs lost during 2006 epidemic, with an overall burden of 45.26 DALYs per million. It varied from 0.01 to 265.62 per million in different states. Karnataka alone contributed as high as 55% of the national burden. Persistent arthralgia was found to impose heavy burden, accounting for 69% of the total DALYs. The productivity loss in terms of income foregone was estimated to be a minimum of Rs. 391 million. Interpretation & conclusion: The chikungunya epidemic in the year 2006 imposed heavy epidemiological burden and productivity loss to the community. The burden of chikungunya in terms of

He belongs to the experts identifying the Alzheimer diseases as a forced aging process. Accepted the theory of L. Hayflick he evaluates the aging process in frame of an evolution model. He states that for aged human beings having already performed the task of reproduction further conditions of living circumstances and even that of death are no more programmed. This hypothesis may have a very negative content at the first sense. But the author rather considers the uncertainty of aging a positive message. He establishes that the occurrence of degenerative processes connecting the aging must be limited by preventive interventions far more efficient than the present possibilities. Concerning these steps we are still on the level of recommendations for preserving our general health and data of relevant science are quite contradictory. Although criteria of "healthy", "qualified" or "assumable" aging are getting defined, we still do not know exactly how we should live optimally and what should we do for this in different epochs of our life. Somatic and psychological parameters are lacking which would be able to signalize the actual level of the aging process in a given person. We, physicians, also do not have exact opinion on the level of severity of dementias at which the patient already lost his her features of personality and individuality on an irreversible way. We have no idea on the phase when the ratio of joy and suffer falls below the value of 1.0 because we still have no tool for its measure. The author pointed the necessity of acceptance of a new preventive attitude and application of new methods in the medical care of the forced

    The carbon geochemistry of serpentinized peridotites and gabbroic rocks recovered at the Lost City Hydrothermal Field (LCHF) and drilled at IODP Hole 1309D at the central dome of the Atlantis Massif (Mid-Atlantic Ridge, 30°N) was examined to characterize carbon sources and speciation in oceanic basement rocks affected by long-lived hydrothermal alteration. Our study presents new data on the geochemistry of organic carbon in the oceanic lithosphere and provides constraints on the fate of dissolved organic carbon in seawater during serpentinization. The basement rocks of the Atlantis Massif are characterized by total carbon (TC) contents of 59 ppm to 1.6 wt% and δ 13C TC values ranging from -28.7‰ to +2.3‰. In contrast, total organic carbon (TOC) concentrations and isotopic compositions are relatively constant (δ 13C TOC: -28.9‰ to -21.5‰) and variations in δ 13C TC reflect mixing of organic carbon with carbonates of marine origin. Saturated hydrocarbons extracted from serpentinites beneath the LCHF consist of n-alkanes ranging from C 15 to C 30. Longer-chain hydrocarbons (up to C 40) are observed in olivine-rich samples from the central dome (IODP Hole 1309D). Occurrences of isoprenoids (pristane, phytane and squalane), polycyclic compounds (hopanes and steranes) and higher relative abundances of n-C 16 to n-C 20 alkanes in the serpentinites of the southern wall suggest a marine organic input. The vent fluids are characterized by high concentrations of methane and hydrogen, with a putative abiotic origin of hydrocarbons; however, evidence for an inorganic source of n-alkanes in the basement rocks remains equivocal. We propose that high seawater fluxes in the southern part of the Atlantis Massif likely favor the transport and incorporation of marine dissolved organic carbon and overprints possible abiotic geochemical signatures. The presence of pristane, phytane and squalane biomarkers in olivine-rich samples associated with local faults at the central

    It was recently observed that dehydration causes shrinkage of brain tissue and an associated increase in ventricular volume. Negative effects of dehydration on cognitive performance have been shown in some but not all studies, and it has also been reported that an increased perceived effort may be required following dehydration. However, the effects of dehydration on brain function are unknown. We investigated this question using functional magnetic resonance imaging (fMRI) in 10 healthy adolescents (mean age = 16.8, five females). Each subject completed a thermal exercise protocol and nonthermal exercise control condition in a cross-over repeated measures design. Subjects lost more weight via perspiration in the thermal exercise versus the control condition (P Dehydration following the thermal exercise protocol led to a significantly stronger increase in fronto-parietal blood-oxygen-level-dependent (BOLD) response during an executive function task (Tower of London) than the control condition, whereas cerebral perfusion during rest was not affected. The increase in BOLD response after dehydration was not paralleled by a change in cognitive performance, suggesting an inefficient use of brain metabolic activity following dehydration. This pattern indicates that participants exerted a higher level of neuronal activity in order to achieve the same performance level. Given the limited availability of brain metabolic resources, these findings suggest that prolonged states of reduced water intake may adversely impact executive functions such as planning and visuo-spatial processing.

    AIMS: This study seeks to describe the impact of AIDS on the city of Copenhagen by estimating potential years of life lost (PYLL) before the age of 65 years and to estimate the impact of AIDS deaths on life expectancy for males and females. METHODS: All AIDS cases reported to the national AIDS...... cancer were the leading causes of PYLL in women. It was shown that AIDS deaths at the top of the epidemic in 1991-95 were responsible for a loss of 0.76 years in life expectancy for men and 0.08 years for women. CONCLUSIONS: AIDS has had a considerable impact on potential years of life lost....... A significant decline in AIDS deaths has been seen since 1995 with an effect on life expectancy for men in the city of Copenhagen....

    Full Text Available The purpose of this paper is to uncover the mechanisms used by the Francoist regime to seize the children of its political opponents, as well as to discuss the problem as depicted in contemporary historical novels. In order to achieve these goals, the paper begins with an inquiry into eugenics, as interpreted by the infamous Spanish psychiatrist Antonio Vallejo Nágera. Further, the author reviews the processes through which biological parents (and/or family lost the legal control over their children, many of whom had their identities changed. Consequently, the analysis focuses on three new historical novels (La voz dormida by Dulce Chacón, Mala gente que camina by Benjamin Prado, and Si a los tres años no he vuelto by Any R. Cañil, which use the mediation of historical memory to recover the remembrance of the lost children of the Francoist regime.

  13. Application and Continued Development of Thin Faraday Collectors as a Lost Ion Diagnostic for Tokamak Fusion Plasmas

    This report summarizes the accomplishment of sixteen years of work toward the development of thin foil Faraday collectors as a lost energetic ion diagnostic for high temperature magnetic confinement fusion plasmas. Following initial, proof of principle accelerator based studies, devices have been tested on TFTR, NSTX, ALCATOR, DIII-D, and JET (KA-1 and KA-2). The reference numbers refer to the attached list of publications. The JET diagnostic KA-2 continues in operation and hopefully will provide valuable diagnostic information during a possible d-t campaign on JET in the coming years. A thin Faraday foil spectrometer, by virtue of its radiation hardness, may likewise provide a solution to the very challenging problem of lost alpha particle measurements on ITER and other future burning plasma machines.

    By use of ICP spectroscopy, energy spectrum analysis, hydrogen tester, image analyzer, the differential scanning calorimetric (DSC) and microscope analysis, the effects of RE on the Porosity, structure and properties of B319 aluminum alloy were studied. The results show that under the 0. 3 C/s slow cooling rate in lost foam casting, the effect of RE on modification and grain size of B319 aluminum alloy is little. With the increase of RE master alloy, the tensile strength and elongation increase. When RE>0. 15%, block-like La2Si2Al3 phase appear, and the tensile strength and elongation decrease. The results also show that the melt hydrogen content and casting porosity can be decreased greatly by adding 0.15% RE to aluminum melt. This is the important reason why RE improves the mechanical properties of casting under lost foam casting condition.

    Full Text Available Abstract Background Measures of premature mortality have been used to guide debates on future health priorities and to monitor the population health status. Standard expected years of life lost (SEYLL is one of the methods used to assess the time lost due to premature death. This article affords an overview of premature mortality in Spain for the year 2008. Methods A population-based study was conducted estimating SEYLL by sex and age groups. SEYLL, a key component of the disability-adjusted life years measure of disease burden, was calculated using Princeton West standard life tables with life expectancy at birth fixed at 80 years for males and 82.5 years for females. Population data and specific death records were obtained from the official registers of the National Institute of Statistics. All data were analysed and prepared in GesMor and Epidat software packages. Results The burden of premature mortality was estimated at 2.1 million SEYLL when age at death is taken into account. Males lost 60.9% and females lost 39.1% of total SEYLL. Malignant tumors (34.5% and cardiovascular diseases (24.0% were the leading categories in terms of SEYLL. Ischaemic heart disease (8.5% and lung cancers (8.0% were the most common specific causes of SEYLL followed by cerebrovascular diseases (5.9%, colorectal cancer (4.1%, road traffic accidents (3.5%, Alzheimer and other dementias (2.9%, chronic obstructive pulmonary disease (2.8%, breast cancer (2.8% and suicides (2.6%. Conclusions In Spain, premature mortality was essentially due to chronic non-communicable diseases. Data provided in this study are relevant for a more balanced health agenda aimed at reducing the burden of premature mortality. This study also represents a first step in estimating the overall burden of disease in terms of premature death and disability.

    The recovery of endangered Lost River suckers (Deltistes luxatus) in Upper Klamath Lake is limited by poor juvenile survival and failure to recruit into the adult population. Poor water quality, degradation of rearing habitat, and toxic levels of microcystin are hypothesized to contribute to low juvenile survival. Studies of wild juvenile suckers are limited in that capture rates are low and compromised individuals are rarely captured in passive nets. The goal of this study was to assess the use of a mesocosm for learning about juvenile survival, movement, and health. Hatchery-raised juvenile Lost River suckers were PIT (passive integrated transponder) tagged and monitored by three vertically stratified antennas. Fish locations within the mesocosm were recorded at least every 30 minutes and were assessed in relation to vertically stratified water-quality conditions. Vertical movement patterns were analyzed to identify the timing of mortality for each fish. Most mortality occurred from July 28 to August 16, 2014. Juvenile suckers spent daylight hours near the benthos and moved throughout the entire water column during dark hours. Diel movements were not in response to dissolved-oxygen concentrations, temperature, or pH. Furthermore, low dissolved-oxygen concentrations, high temperatures, high pH, high un-ionized ammonia, or high microcystin levels did not directly cause mortality, although indirect effects may have occurred. However, water-quality conditions known to be lethal to juvenile Lost River suckers did not occur during the study period. Histological assessment revealed severe gill hyperplasia and Ichthyobodo sp. infestations in most moribund fish. For these fish, Ichthyobodo sp. was likely the cause of mortality, although it is unclear if this parasite originated in the rearing facility because fish were not screened for this parasite prior to introduction. This study has demonstrated that we can effectively use a mesocosm equipped with antennas to learn

    Two field studies using 1,004 "lost letters" were designed to test the hypotheses that returned responses would be greater in small towns than from a city, that addressees' affiliation with a group either (1) opposed to physical education in schools, (2) supporting gay and lesbian teachers, or (3) advocating Creationism or Darwinism would reduce the return rate. Of 504 letters "lost" in Study A, 163 (32.3%) were returned in the mail from residents of southeast Louisiana and indicated across 3 addressees and 2 sizes of community, addressees' affiLiations were not associated with returned responses. Community size and addressees' affiliations were associated with significantly different rates of return in the city. Return rates from sites within a city were lower when letters were addressed to an organization which opposed (teaching) health education in the schools than to one supporting daily health education. Of 500 letters "lost" in Study B, 95 (19.0%) were returned from residents of northwest Florida and indicated across 5 addressees and 2 sizes of community, addressees' affiliations were significantly associated with returned responses overall (5 addressees) and in small towns (control, Creationism, Darwinism addressees), but not with community size. Community size and addressees' affiliations were associated with significantly different rates of return in small towns, with returns greater than or equal to those in the city (except for the addressee advocating teaching Darwinism in public schools). The present findings appear to show that applications of the lost letter technique to other divisive social issues are useful in assessing public opinion.
