    Bella, Giovanni

    This paper is aimed at describing the whole set of necessary and sufficient conditions for the emergence of multiple equilibria and global indeterminacy in the standard endogenous growth framework with learning by doing. The novelty of this paper relies on the application of the original Bogdanov-Takens bifurcation theorem, which allows us to characterize the full dynamics of the model, and determine the emergence of an unavoidable poverty trap.

  4. Normal Forms for Retarded Functional Differential Equations and Applications to Bogdanov-Takens Singularity

    Science.gov (United States)

    Faria, T.; Magalhaes, L. T.

    The paper addresses, for retarded functional differential equations (FDEs), the computation of normal forms associated with the flow on a finite-dimensional invariant manifold tangent to invariant spaces for the infinitesimal generator of the linearized equation at a singularity. A phase space appropriate to the computation of these normal forms is introduced, and adequate nonresonance conditions for the computation of the normal forms are derived. As an application, the general situation of Bogdanov-Takens singularity and its versal unfolding for scalar retarded FDEs with nondegeneracy at second order is considered, both in the general case and in the case of differential-delay equations of the form ẋ( t) = ƒ( x( t), x( t-1)).

    The importance of maintaining roadside verges as a conservation measure is discussed. The recognition of this importance should lead to cooperation between conservationists and highway authorities to ensure the preservation of these structures without compromising highway engineering. Some aspects of the potential for creative conservation of motorways are surveyed, and the similarity between motorways and railways is explored. (18 references)

    Objective: To determine and evaluate the method of localization of anal verge by multislice spiral CT. To provide an imaging reference for operative guidance of low-rectal cancer. Methods Forty eight consecutive adult patients suspected of abnormalities other than rectal disease were evaluated with abdominal and pelvic CT scans since August, 2009. They were divided into two groups based on sex and age. There were 23 men and 25 women. The ages of young group were 28 to 50 years and the average age was 41 years. The ages of elderly group were 52 to 81 years and the average age was 64 years. A small cotton ball dipped with contrast media was put at the anal verge as a marker and CT scans were performed with 64-slice spiral CT scanner. The distances between the cotton balls and the lower margin of the pubis combination (La), the lower margin of the Sth sacral vertebra (Lb), the inferior aperture of minor pelvis (Lc) and the lower margin of the basement of external anal sphincter (Ld) were measured on the mid- sagittal images obtained by MPR. The averages, the standard deviations (s), the 95% and 80% confidence intervals of La, Lb, Lc and Ld were calculated. We took the intervals of ±1.96 s or ±1.28 s 0.05) between two different sex groups [male group, (10.0±1.2) mm], female group, (9.6±1.2) mm and between two age groups [young group, (9.6±1.2) mm, elderly group, (9.9±1.3) mm]. Conclusions: The lower margin of the basement of external anal sphincter was a useful anatomic landmark for localizing the anal verge, and could be definitely identified on the middle sagittal pelvic CT image. The distance between the structure and anal verge is constant enough and can be used in measuring distance from low rectal lesion to the anal verge. (authors)

    A crisis looms over the scientific enterprise. Not a day passes without news of retractions, failed replications, fraudulent peer reviews, or misinformed science-based policies. The social implications are enormous, yet this crisis has remained largely uncharted—until now. In Science on the Verge, luminaries in the field of post-normal science and scientific governance focus attention on worrying fault-lines in the use of science for policymaking, and the dramatic crisis within science itself. This provocative new volume in The Rightful Place of Science also explores the concepts that need to be unlearned, and the skills that must be relearned and enhanced, if we are to restore the legitimacy and integrity of science.

    Full Text Available Introduction. Face transplantation (FT is an innovative achievement of modern reconstructive surgery and is on the verge of becoming a common surgical opportunity. This review article was compiled to provide an update on this surgical field, especially regarding clinical outcomes, benefits, and complications implied. Methods. We performed an extensive research on all English-language Medline articles, case reports, and reviews published online until September 15, 2013. Used search terms were “face transplantation,” “face transplant,” “facial transplantation,” “facial transplant,” “face allograft,” and “facial allograft.” Results. To date 27 FTs have been performed worldwide. 19 of these cases have been published in the Medline database. Long-term follow-up reports of FT cases are rare. Three deaths associated with the procedure have occurred to date. The clinical outcomes of FT are satisfying. Reinnervation of sensation has been faster than motor recovery. Extensive functional improvements have been observed. Due to strict immunosuppression protocols, no case of hyperacute or chronic rejection and no graft-versus-host disease have occurred to date. Conclusions. As studies on long-term outcomes are missing, particularly regarding immunosuppression-related complications, FT will stay experimental for the next years. Nevertheless, for a small group of patients, FT already is a feasible reconstructive option.

    Vehicular emissions of NO x and NH 3 result in elevated concentrations of nitrogen at roadside verges. To determine the extent that vehicular nitrogen emissions, disturbance and management affect the vegetation composition of road verges, a survey of 92 verges in Scotland was carried out with sites stratified by background nitrogen deposition and road type. NO x and NH 3 concentrations were monitored at 15 key sites for a year, and showed a decreasing gradient with increasing distance from the road. Ellenberg fertility indices of the vegetation communities also showed a general decrease with increasing distance from the road, but there was no straightforward correlation with NO x and NH 3 air concentrations between sites. Cover of bare ground, ruderal species and salt-tolerant species were highest at the verge edge. The proximity of the verge to traffic is important both in terms of NO x and NH 3 gradients, but also for deposited salt, grit and physical disturbance. - NO x , NH 3 and road verge vegetation Ellenberg fertility indices decline with distance from traffic

  17. Effect of different mowing regimes on butterflies and diurnal moths on road verges

    Directory of Open Access Journals (Sweden)

    Valtonen, A.

    2006-12-01

    Full Text Available In northern and central Europe road verges offer alternative habitats for declining plant and invertebrate species of semi-natural grasslands. The quality of road verges as habitats depends on several factors, of which the mowing regime is one of the easiest to modify. In this study we compared the Lepidoptera communities on road verges that underwent three different mowing regimes regarding the timing and intensity of mowing; mowing in mid-summer, mowing in late summer, and partial mowing (a narrow strip next to the road. A total of 12,174 individuals and 107 species of Lepidoptera were recorded. The mid-summer mown verges had lower species richness and abundance of butterflies and lower species richness and diversity of diurnal moths compared to the late summer and partially mown verges. By delaying the annual mowing until late summer or promoting mosaic-like mowing regimes, such as partial mowing, the quality of road verges as habitats for butterflies and diurnal moths can be improved.

  20. Roadside verges as habitats for endangered lizard-orchids (Himantoglossum spp.): Ecological traps or refuges?

    Alterations in traditional land use practices have led to severe declines in the area of semi-natural grasslands, thereby seriously threatening plant and animal species dependent on these habitats. Small anthropogenic managed habitats, like roadsides can act as refuges and might play an important role in conserving these species. Colonization of roadside verges by endangered lizard orchids (Himantoglossum spp.) has long been known, but few studies have systematically explored the suitability of roadside habitats for these orchids and the impact of roads on them. In this paper we present results of targeted surveys of three lizard orchid taxa on roadsides from eight European countries. During these surveys we searched for lizard orchids inhabiting roadside verges and recorded their distance from road, aspects of the roadside environment, as well as vegetative and reproductive characteristics of individual plants. We found large numbers of lizard orchids on roadside verges. Distance from roads was not uniformly distributed: orchids occurred more closely to roads than expected by chance. This suggests that regular management of roadsides (e.g. mowing) might enhance colonization and survival of lizard orchids. On the other hand, we also found that close proximity to roads negatively affects reproductive success, suggesting that the immediate vicinity of roads might act as an ecological trap (i.e. favorable in terms of colonization and survival but unfavorable in terms of reproduction). Nonetheless, the fact that significant and viable populations are maintained at roadsides suggests that traditionally managed roadside verges may allow long-term persistence of lizard orchid populations and may serve as refuges in a landscape context.

  1. Lead concentrations and reproductive success in European starlings Sturnus vulgaris nesting within highway roadside verges

    In 1981, the authors studied lead concentrations and reproductive success in free-living European starlings Sturnus vulgaris nesting within the verges of two Maryland highways with different traffic volumes, Route 197(average daily traffic volume[ADT] = 10,800 vehicles) and the Baltimore-Washington Parkway (ADT=52,500 vehicles) and a nearby control area. Concentrations (mg kg-1 dry weight) of lead in the ingesta (84-94 mg kg-1), carcasses (4.0-9.6 mg kg-1)and feathers (6.8-52 mg kg-1) of Parkway nestlings and adults were 3 to 13 times those found in starlings from the control area, whereas lead concentrations in the ingesta and tissues of starlings from the verge of Route 197 were similar to those of controls. Activity of delta-aminolevulinic acid dehydratase (ALAD) in red blood cells (RBCs) of adult and nestling starlings from the Parkway was depressed from 43 to 60% compared to controls. RBC ALAD activity in adults from nests along Route 197 was similar to that of adult starlings from the control area, but that of their young was depressed 17%. Haemoglobin concentrations (-16%) and haematocrits (-10%) in Parkway nestlings were depressed compared with those of nestlings from the other two study areas, whereas those of adults were not affected. Clutch size, number of young hatched and the number of young in nests 1 to 3 days before fledging were similar among sites, as were body weights of adults and prefledging weights of their young. However, brain weights of Parkway nestlings were lower (P < 0.05) than those of nestlings from the other study areas. Results suggests that lead within verges of major highways probably does not pose a serious hazard to adult ground-foraging songbirds. However, the effects of lead-induced reductions in haemoglobin concentration, haematocrit, RBC ALAD activity and brain weight on the postfledging survival of their young are not known.

  4. Perturbations of linear delay differential equations at the verge of instability.

    Science.gov (United States)

    Lingala, N; Namachchivaya, N Sri

    2016-06-01

    The characteristic equation for a linear delay differential equation (DDE) has countably infinite roots on the complex plane. This paper considers linear DDEs that are on the verge of instability, i.e., a pair of roots of the characteristic equation lies on the imaginary axis of the complex plane and all other roots have negative real parts. It is shown that when small noise perturbations are present, the probability distribution of the dynamics can be approximated by the probability distribution of a certain one-dimensional stochastic differential equation (SDE) without delay. This is advantageous because equations without delay are easier to simulate and one-dimensional SDEs are analytically tractable. When the perturbations are also linear, it is shown that the stability depends on a specific complex number. The theory is applied to study oscillators with delayed feedback. Some errors in other articles that use multiscale approach are pointed out.

    Full Text Available Family is an integral part of society in all cultures and time periods. Its mission is to raise the next generation, which will be able to continue and further develop knowledge and experience of the previous generation. The modern history of family entrepreneurship in Czech Republic restarted back in 1989, i.e., straight after the fall of the communist regime and restoration of the democratic system. People went into business with enthusiasm and the most successful ones among then now stand on the verge of generation handover. The literature review prepared using the desk-research method is mainly based on foreign professional sources – monographic publications, scientific articles published in professional magazines, accessed from Proquest, Web of Science, Ebsco, Scopus and some other databases. The objective of our quantitative research was to evaluate, based on parameter E (Experience, the generational representation of family members in relation to leadership and ownership of businesses. Quantitative research was based on the use of statistical and graphical data processing methods, including SPSS software, applied for the authors’ own empirical investigation based on the international methodology of family company review through the F-PEC scale, the Experience parameter (Astrachan et al., 2002. It was shown that accumulation of business experience in business families is still mainly concentrated on the founding generation of entrepreneurs. In the conclusion of the paper, deduction and generalisation methods have been applied.

  8. Distribution and abundance of bee forage flora across an agricultural landscape – railway embankments vs. road verges

    Directory of Open Access Journals (Sweden)

    Małgorzata Wrzesień

    2016-09-01

    Full Text Available In this study, we evaluated if railway embankments and road verges create refuge habitats for bee flora across agricultural landscape. The survey was conducted in 2009–2012, in the Lublin Province, SE Poland. Data on the bee forage flora were obtained while making floristic charts along 60 transect plots × 300 m, with a total length of 18 000 m, for each type of linear structure. Forage bee flora was compared with respect to species richness, diversity, and evenness indices. The canonical correspondence analysis (CCA was used to characterize relationship between species composition and environmental variables. The bee forage species richness and abundance were significantly greater on railway embankments than on road verges. The composition of species varied considerably; the number of bee forage species common to both habitats was only approximately 38% in entire data set. Most good-value bee forage species were recorded along the embankments of railways with an intermediate traffic volume. Bee forage species diversity benefits from the location of habitat elements (forests or meadows, primarily if the distance is <50 m. The lack of dense patches of valuable bee forage species in the road verges was related to the high density of non-nectariferous graminoids. Our results demonstrate how the value of man-made areas in an agricultural ecosystem can vary with respect to floral resources across the landscape, suggesting that it is inappropriate to generalize about agricultural systems as a whole without first addressing differences among habitats.

  11. PERSPECTIVE: On the verge of dangerous anthropogenic interference with the climate system?

    Science.gov (United States)

    Kriegler, Elmar

    2007-03-01

    The recent publication of the summary for policy makers by Working Group I of the Intergovernmental Panel on Climate Change (IPCC) [1] has injected a renewed sense of urgency to address climate change. It is therefore timely to review the notion of preventing 'dangerous anthropogenic interference with the climate system' as put forward in the United Nations Framework Convention on Climate Change (UNFCCC). The article by Danny Harvey in this issue [2] offers a fresh perspective by rephrasing the concept of 'dangerous interference' as a problem of risk assessment. As Harvey points out, identification of 'dangerous interference' does not require us to know with certainty that future climate change will be dangerous—an impossible task given that our knowledge about future climate change includes uncertainty. Rather, it requires the assertion that interference would lead to a significant probability of dangerous climate change beyond some risk tolerance, and therefore would pose an unacceptable risk. In his article [2], Harvey puts this idea into operation by presenting a back-of-the-envelope calculation to identify allowable CO2 concentrations under uncertainty about climate sensitivity to anthropogenic forcing and the location of a temperature threshold beyond which dangerous climate change will occur. Conditional on his assumptions, Harvey delivers an interesting result. With the current atmospheric CO2 concentration exceeding 380 ppm, a forcing contribution from other greenhouse gases adding an approximate 100 110 ppm CO2 equivalent on top of it, and a global dimming effect of aerosols that roughly compensates for this contribution (albeit still subject to considerable uncertainty) ([1], figures SPM-1 and 2), we are on the verge of or even committed to dangerous interference with the climate system if we (1) set the risk tolerance for experiencing dangerous climate change to 1% and (2) allocate at least 5% probability to the belief that climate sensitivity is 4

    The Kanda tribe is one of the lesser known small tribes of Bangladesh with an estimated population of about 1700 people (according to them), and on the verge of extinction as a separate entity. To some extent, they have assimilated with the surrounding mainstream Bengali-speaking population, but they still maintain their cultural practices including traditional medicinal practices, for which they have their own tribal healers. Nothing at all has been documented thus far about their traditional medicinal practices and formulations, which are on the verge of disappearance. The Kanda tribe can be found only in scattered tea gardens of Sreemangal in Sylhet district of Bangladesh; dispersion of the tribe into small separated communities is also contributing to the fast losing of traditional medicinal practices. The objective of the present study was to conduct an ethnomedicinal survey among the traditional healers of the Kanda tribe (in fact, only one such healer was found after extensive searches). Information was collected from the healer with the help of a semi-structured questionnaire and the guided field-walk method. A total of 24 formulations were obtained from the healer containing 34 plants including two plants, which could not be identified. Besides medicinal plants, the Kanda healer also used the body hairs of the Asiatic black bear (Ursus thibetanus) and bats (Pteropus giganteus giganteus) in one of his formulation for treatment of fever with shivering. The ailments treated by the Kanda healer were fairly common ailments like cuts and wounds, skin diseases, helminthiasis, fever, respiratory problems (coughs, asthma), gastrointestinal disorders (stomach pain, constipation, diarrhea), burning sensations during urination, various types of pain (headache, body ache, toothache, ear ache), conjunctivitis, poisonous snake, insect or reptile bites, jaundice, and bone fractures.

    Full Text Available This study focuses on how children's transitions to and from preschool classes are organized in different schools. Principal’s arguments for this organization were sought via a web-based survey and analyzed using the frame factor theory in addition to theories of practical sense and the concept of continuity. The results show that children tend to make more transitions between social communities the younger they are. The distribution of the principal’s answers show that the majority of them, because of external conditions, split the preschool groups to new classes in the transition to preschool class. However, the same movements are not indicated in the transition to first grade. The results show how the work of organizing chidren’s transitions represent a complex web of external actual conditions as the number of children and the recruitment area of the school, the internal logics and ideas about what is best for children and best for continued learning as well as the school's own traditions of working with transitions. Föreliggande studie fokuserar på hur barns övergångar till och från förskoleklass organiseras på olika skolor. Via en webbaserad enkät söks skolledares argument för denna organisering. I analysen nyttjas ett ramfaktorteoretiskt tänkande som kompletteras med teorier om praktiskt förnuft samt kontinuitetsbegreppet. Resultaten visar att barn tenderar att göra fler övergångar mellan barngrupper och sociala gemenskaper ju yngre de är. Fördelningen av skolledarnas svar visar att majoriteten, på grund av yttre villkor, delar förskolegrupperna till nya klasser i övergången till förskoleklass. Däremot indikeras inte samma rörlighet i övergången till årskurs 1. Resultaten visar hur arbetet med att organisera övergångarna utgör en komplex väv av yttre faktiska villkor som barnantal och upptagningsområdets storlek, av inre logiker och föreställningar om vad som är det bästa för barnen och det b

    Mean Reynolds stress profiles and instantaneous Reynolds stress structures are investigated in a self-similar adverse pressure gradient turbulent boundary layer (APG-TBL) at the verge of separation using data from direct numerical simulations. The use of a self-similar APG-TBL provides a flow domain in which the flow gradually approaches a constant non-dimensional pressure gradient, resulting in a flow in which the relative contribution of each term in the governing equations is independent of streamwise position over a domain larger than two boundary layer thickness. This allows the flow structures to undergo a development that is less dependent on the upstream flow history when compared to more rapidly decelerated boundary layers. This APG-TBL maintains an almost constant shape factor of H = 2.3 to 2.35 over a momentum thickness based Reynolds number range of Re δ 2 = 8420 to 12400. In the APG-TBL the production of turbulent kinetic energy is still mostly due to the correlation of streamwise and wall-normal fluctuations, 〈uv〉, however the contribution form the other components of the Reynolds stress tensor are no longer negligible. Statistical properties associated with the scale and location of sweeps and ejections in this APG-TBL are compared with those of a zero pressure gradient turbulent boundary layer developing from the same inlet profile, resulting in momentum thickness based range of Re δ 2 = 3400 to 3770. In the APG-TBL the peak in both the mean Reynolds stress and the production of turbulent kinetic energy move from the near wall region out to a point consistent with the displacement thickness height. This is associated with a narrower distribution of the Reynolds stress and a 1.6 times higher relative number of wall-detached negative uv structures. These structures occupy 5 times less of the boundary layer volume and show a similar reduction in their streamwise extent with respect to the boundary layer thickness. A significantly lower percentage

  16. Investigation of the effects of slow-release fertilizer and struvite in biodegradation in filter drains and potential application of treated water in irrigation of road verges.

    Filter drains are usually laid along the margins of highways. Highway runoffs are polluted with hydrocarbons and high levels of total dissolved solids. Therefore, effective pollution removal mechanism is necessary in order to avoid contamination of surrounding soils and groundwater. Biodegradation is amongst pollution removal mechanisms in filter drains, but it is a relatively slow process which is dependent on wide range of factors including the type of pollutant and availability of nutrients. This paper reports on a study conducted to investigate the impact of slow-release fertilizer and struvite in enhancement of biodegradation of hydrocarbon in filter drains. Filter drain models incorporated with geotextile were challenged with cumulative oil loading of 178 mg/m 2 /week with a view to comparing the efficiency of these two nutrient sources under high oil pollution loading and realistic rainfall conditions of 13 mm/week. Nutrients and street dust were applied at one-off rate of 17 g/m 2 and 1.55 g/rig to provide nutrient enhancement and simulate field conditions respectively. The impact of the nutrients was studied by monitoring bacterial and fungal growth using nutrient agar, Rose Bengal Agar media and CO2 evolution. EC, pH, heavy metals, TPH, elemental analysis and SAR were used to investigate water quality of effluent of filter drains for potential application as irrigation fluid for trees and flowers planted on road verges. The results show that nutrient application encouraged microbial activities and enhanced biodegradation rates with differences in type of nutrient applied. Also, it was observed that incorporation of geotextiles in filter drains improved pollution retention efficiency and there is a potential opportunity for utilization of struvite in SuDS systems as sustainable nutrient source.

    Full Text Available La philanthropie semble avoir en Asie suscité un net engouement ces dernières décennies. En Thaïlande toutefois, ces largesses financières à l’égard des œuvres du bouddhisme ou des fondations patronnées par la famille royale ne sont pas toujours l’illustration d’un total désintéressement. En effet, en contrepartie de cette générosité bien orientée, le donateur peut espérer recevoir – voire réclamer – une des multiples décorations officiellement attribuées par le souverain. Lorsque le donateur est une donatrice, certaines médailles donnent droit à des titres placés dorénavant devant le prénom qui ont pour effet de distinguer une nouvelle noblesse. Cette ferveur pour les décorations a pu entraîner dans le passé des phénomènes de corruption de la part de hauts responsables de monastères bouddhiques habilités à délivrer des certificats de donations. Au lieu de réelle philanthropie ou même d’évergétisme à la mode antique, c’est bien de course aux honneurs ou philotimie qu’il convient ici de parler.We can at times talk of a craze for philanthropy in Asia. However, in Thailand, that financial liberality for Buddhism charitable works or the plethora of foundations patronized by members of the royal family are not always a proof a perfect unselfishness. Actually, in return for this well connected generosity, the donator expects to receive—or even ask for—one of numerous decorations officially bestowed by the king. Even, in the case of the donator being a woman, some of these medals of higher ranks have for effect that therefore a special title is positioned ahead of the personal name just like if it was to create a new kind of nobility. In the past, that enthusiasm for royal decorations has generated cases of corruption by some high-level monastery hierarchy empowered for the delivery of donation certificates. Instead of true philanthropy or even antic style evergetism, we should talk here of

    1995-01-01

    It is no coincidence that x-radiation was discovered in the late 19th century. Electrical phenomena were under vigorous study at the time. It was a heyday for universities; natural sciences advanced rapidly, and the increasing wealth in society sped up research in various fields. If Roentgen had not discovered the x-rays, some other researcher would certainly have found them around the same time. People were enthralled by x-rays, and the general climate in the early years did not favour advocating for radiation protection, even though a hundred years ago it was already recognised that radiation also poses a risk to health. In addition to improved knowledge and advanced technology, more efficient control measures by the authorities have also helped to improve radiation protection gradually. Study of the damage to health caused by the atomic bombs in Hiroshima and Nagasaki has substantially enhanced the body of knowledge on radiation protection. The whole spectrum of electromagnetic radiation has gradually opened up to researchers. The effects of rays on the body vary greatly, depending on their wavelength. Considerable amounts of x- radiation have also been detected in space. The effects of these x-rays on people are mostly eliminated by the atmosphere. When radiation is used safely, a carefully conducted x-ray examination always has far more advantages than disadvantages. Nowadays it is also possible to utilise contrast mediums and magnetic imaging. Magnetic fields and the radio-frequency waves used in magnetic imaging have not been found to cause any permanent damage to the body. It may well be that in future magnetic imaging will replace all x-ray examinations. (orig.) (2 figs.)

  7. Fog harvesting on the verge of economic competitiveness

    2010-07-01

    Water scarcity is the bottleneck for agriculture and development of Peru’s coast and subject to aggravation due to climate change. Until present day, Peru’s coast in general and the Lima Metropolitan Area (LMA) in particular have enjoyed to a great extend the effect of the country’s high altitude glaciers that serve as a buffer for the capital’s water demand during the highland dry season. However, climate models predict the disappearance of this buffer system below 5.500 masl by 2015, leaving one of the driest places on earth with yet another decrease in freshwater supply (Zapata 2008). The deviation of water resources from the highlands has led already to allocation conflicts. Peru is in urgent need of new concepts for water management. Fog harvesting was introduced to South America in the 1980s and has since been implemented at various locations in North and Central America, Europe, Africa, Asia and Australia. The Standard Fog Collector (SFC) as described by Schemenauer and Cereceda (1994) has proven to be a successful instrument for this purpose. Apart from a number of small scale investigations, the design of the collector has barely been changed over the past three decades (e.g. Gioda et al. 1993). Within the framework of the presented project, financed primarily by the Global Exploration Fund of the National Geographic Society and Bayer AG, new fog collectors were designed at pilot and full scale. Best results in terms of simplicity of construction and water yield were obtained by a metal frame structure called Eiffel. While covering the same amount of space as an SFC and using the same Raschel 65% shadow net, the Eiffel collector harvested up to 2.650 liters of water within a frame of 8x4m compared to up to 600 liters of water harvested by a SFC at the same location. In combination with a simplified maintenance concept, our collectors present an economically competitive alternative to water supply by truck delivery in a region that is not likely to be connected to a centralized water supply system within the next two decades. At the given water price and a given location, we calculate a break-even point after 8-9 years following the investment.

    2018-05-01

    CubeSats are small satellites built in standard sizes and form factors, which have been growing in popularity but have thus far been largely ignored within the field of astronomy. When deployed as space-based telescopes, they enable science experiments not possible with existing or planned large space missions, filling several key gaps in astronomical research. Unlike expensive and highly sought after space telescopes such as the Hubble Space Telescope, whose time must be shared among many instruments and science programs, CubeSats can monitor sources for weeks or months at time, and at wavelengths not accessible from the ground such as the ultraviolet, far-infrared and low-frequency radio. Science cases for CubeSats being developed now include a wide variety of astrophysical experiments, including exoplanets, stars, black holes and radio transients. Achieving high-impact astronomical research with CubeSats is becoming increasingly feasible with advances in technologies such as precision pointing, compact sensitive detectors and the miniaturization of propulsion systems. CubeSats may also pair with the large space- and ground-based telescopes to provide complementary data to better explain the physical processes observed.

    To estimate the incidence of hepatic steatosis (HS) and liver fibrosis (LF) in patients with diabetes mellitus (DM), by applying the noninvasive techniques of liver fibroelastometry (LFE) and a battery of fibrotests (FTs); to determine their diagnostic value and to identify factors influencing the development of LF. A comprehensive examination was made in 82 diabetic patients (mean age, 56.7±12.7 years; p=0.033). The data were statistically evaluated using ROC curve analysis, correlation and single-factor analyses of variance, and multiple logistic regression analysis. FTs and LFE revealed that the DM patients had liver cirrhosis (LC) (METAVIR F4) in 12 (14.6%) and 15 (18.2%) patients, respectively. Those showed clinically significant fibrosis (METAVIR fibrosis stages F2-3) in 19 (23.1%) and 23 (28%) patients, respectively. Varying degrees of HS were present in 79 (96.3%) patients. LFE and FTs demonstrated comparable results in detecting LC (the area under the receiver operating characteristics curve (AUROC), 0.83 and 0.81, respectively). The development of LF is influenced by factors, such as the degree of HS, obesity, the activity of an inflammatory process, and the level of alanine aminotransferase and α2-macroglobulin. Diabetic patients are at high risk for NAFLD to develop LF and LC. LFE and FTs showed a comparably high accuracy in the diagnosis of LC in patients with DM and these may be used for screening. With allowance made for the existing risk factors of LF and LC, it is necessary to identify groups of patients with DM for further examination and follow-up. Patients who are diagnosed with stage F4 should be examined carefully to evaluate concurrent diseases and to make liver biopsy.

    Israel has a universal-national healthcare system and a progressive health policy legislation which, together, provide its residents with high-level healthcare services and either free or highly subsidized coverage without any pre-existing conditions. However, it is surprising that shared decision making (SDM) practices and policy are not an integral part of Israel's healthcare system. The purpose of this overview is to describe the gap between the organizational-infrastructure compatibility of Israel's universal healthcare policy and the efforts needed to advance SDM as part of routine healthcare practice. Review of recent research and education initiatives will be described as well as recommendations for policy and clinical practice. Copyright © 2017. Published by Elsevier GmbH.

    Algeria has not forged, during the years 2000, a natural gas 'diplomacy' comparable - by far - to the Russian one. Three obstacles were on its way: first, proved reserves are six time less than those of the top world producer; secondly, its maneuver margin has been for a long time reduced by long term supply contracts (to South Europe essentially); thirdly, Algeria experienced a great political difficulty to define a strategy that could be adapted to the new world context of rarefied energy sources, a context that is clearer since 2003-2004. The author explains the changes that have happened within these three constraint lines since 2008. He notably comments the geopolitical incidence of the end of the long term sale contracts, the role of LNG in the global energy mix, and analyses the Algerian gas production perspectives and the possibility of an agreement between gas producing countries

Next, the report analyses the legal context into which the proposal for a Directive fits. It notes that Community las is now more attuned to the requirements that allow the accomplishment of missions of general interest. On the basis of this analysis, the report then adopts a position for the maintenance of the public service obligations, for the strict respect of confidentiality of commercial information and, therefore, for the transparency of accounting limited to regulatory bodies, and for an opening up of competition limited to the industrial consumers for whom energy is a factor of their competitiveness.

    Wiens, Jenna; Shenoy, Erica S

    2018-01-06

    The increasing availability of electronic health data presents a major opportunity in healthcare for both discovery and practical applications to improve healthcare. However, for healthcare epidemiologists to best use these data, computational techniques that can handle large complex datasets are required. Machine learning (ML), the study of tools and methods for identifying patterns in data, can help. The appropriate application of ML to these data promises to transform patient risk stratification broadly in the field of medicine and especially in infectious diseases. This, in turn, could lead to targeted interventions that reduce the spread of healthcare-associated pathogens. In this review, we begin with an introduction to the basics of ML. We then move on to discuss how ML can transform healthcare epidemiology, providing examples of successful applications. Finally, we present special considerations for those healthcare epidemiologists who want to use and apply ML. © The Author(s) 2017.

    The cyclisation of a short chain into a ring provides fascinating scenarios in terms of transforming a finite array of spins into a quasi-infinite structure. If frustration is present, theory predicts interesting quantum critical points, where the ground state and thus low-temperature properties of a material change drastically upon even a small variation of appropriate external parameters. This can be visualised as achieving a very high and pointed summit where the way down has an infinity of possibilities, which by any parameter change will be rapidly chosen, in order to reach the final ground state. Here we report a mixed 3d/4f cyclic coordination cluster that turns out to be very near or even at such a quantum critical point. It has a ground state spin of S = 60, the largest ever observed for a molecule (120 times that of a single electron). [Fe10Gd10(Me-tea)10(Me-teaH)10(NO3)10].20MeCN forms a nano-torus with alternating gadolinium and iron ions with a nearest neighbour Fe-Gd coupling and a frustrating next-nearest neighbour Fe-Fe coupling. Such a spin arrangement corresponds to a cyclic delta or saw-tooth chain, which can exhibit unusual frustration effects. In the present case, the quantum critical point bears a `flatland' of tens of thousands of energetically degenerate states between which transitions are possible at no energy costs with profound caloric consequences. Entropy-wise the energy flatland translates into the pointed summit overlooking the entropy landscape. Going downhill several target states can be reached depending on the applied physical procedure which offers new prospects for addressability.

    Full Text Available The aim of the present study was twofold: a to verify the previously detected regularities in a group of subjects larger than the one employed in a pilot study, and b to define the internal structure of the hierarchy of values that can be squandered as a result of doping. For the study, eighty-nine 16-18-year-old students from the fencing, athletics, martial arts, and football classes of the School of Championship in Sports were recruited. Experimental technique developed by Mroczkowska called “Perception of the risk of doping” was employed to individually rank the highly regarded values (e.g., health, medals won, physical appeal, mental balance, financial bonuses, and social respect that can be lost as a consequence of the use of illegal stimulants. It appears that young athletes would declaratively resign themselves from the loss of a financial bonus rather than from the loss of the social respect and attributes of self-integrity, such as physical and mental health. The detected correlations suggest that the rewarding value of a medal has an internal dimension: it externalizes a sense of self-confidence and confirms high self-esteem. The results indicate that, as perceived by the young, winning a medal with the help of doping is an illusion that does not allow to verify one’s own skills and limitations.

    Full Text Available Among Romanian historical communities, two are currently close to ethnic and linguistic assimilation, due to their small number of members, the impossibility of claiming their cultural and linguistic rights, as well as the refusal of Balkan states to protect them. These groups are the Meglenoromanians and Istroromanians. In this study, we make a historical and ethnographic analysis of the small Meglenoromanian community, which was united until the Balkan wars, was split in two through the division of the Meglen land between Greece and the Serbian-Croatian-Slovenian Kingdom (1913, and then split again into two groups through the expulsion of Muslim Meglenoromanians to Turkey (1921 and the colonization of over 2 000 persons from Romania (in the Quadrilater, beginning in 1925, and afterwards in Cerna village, Tulcea county, in 1940.

    We investigate the limits of the single-domain model in (Ga,Mn)As by performing detailed angle- and field-dependent magnetotransport measurements in samples with differing magnetic anisotropies. For this purpose, a series of (Ga,Mn)As layers with Mn concentrations of {proportional_to}5% was grown by low-temperature molecular-beam epitaxy on relaxed (In,Ga)As/GaAs templates with different In-concentrations, realizing different strain conditions from compressive to tensile. In past investigations we have elucidated the strain dependence of the magnetic anisotropy and of the anisotropic magnetoresistance employing a single-domain model. In order to analyze the break-down of the single-domain model, we now study in detail magnetization reversal processes by sweeping an external magnetic field along selected axes. The magnetic-field sweeps are compared with a series of angle-dependent magnetotransport measurements, carried out at weak external magnetic fields.

  14. A country on the verge of malaria elimination--the Kingdom of Saudi Arabia.

    Directory of Open Access Journals (Sweden)

    Michael Coleman

    Full Text Available Significant headway has been made in the global fight against malaria in the past decade and as more countries enter the elimination phase, attention is now focused on identifying effective strategies to shrink the malaria map. Saudi Arabia experienced an outbreak of malaria in 1998, but is now on the brink of malaria elimination, with just 82 autochthonous cases reported in 2012. A review of published and grey literature was performed to identify the control strategies that have contributed to this achievement. The number of autochthonous malaria cases in Saudi Arabia decreased by 99.8% between 1998 and 2012. The initial steep decline in malaria cases coincided with a rapid scaling up of vector control measures. Incidence continued to be reported at low levels (between 0.01 and 0.1 per 1,000 of the population until the adoption of artesunate plus sulfadoxine-pyrimethamine as first line treatment and the establishment of a regional partnership for a malaria-free Arabian Peninsula, both of which occurred in 2007. Since 2007, incidence has decreased by nearly an order of magnitude. Malaria incidence is now very low, but a high proportion of imported cases, continued potential for autochthonous transmission, and an increased proportion of cases attributable to Plasmodium vivax all present challenges to Saudi Arabia as they work toward elimination by 2015.

  17. Challenge in the public acceptance and cooperation in the verge of building the first nuclear power plant in Indonesia - 59119

    2012-01-01

    Document available in abstract form only. Full text of publication follows: Indonesia plans to build the first nuclear power plant (NPP) to solve the country's energy problems. One of the challenges that must be handled before establishing the first NPP is the presence of anti-nuclear groups that have successfully made the government postpone its plan several times since the first nuclear research reactor was established in Bandung (1972). The basis for the groups' dissent is the presence, and handling of radioactive waste. Further, the general public perception - even among educated Indonesians - is that Indonesia's experts lack knowledge about nuclear technology, even though nuclear technology has been studied in Indonesia since 1954. So, the problem is one of disseminating information about nuclear technology. To address this challenge, the National Atomic Energy Board (BATAN) of Indonesia has to redesign its public outreach strategy by collaborating with the educational institutions and communications organizations. Gadjah Mada University is the only university in Indonesia offering a nuclear-engineering curriculum. Therefore, a teaming arrangement with this institution seems appropriate to help improve the public's general knowledge about nuclear technology. There are several strategies that could be designed within the frame work of collaboration. The first strategy is to introduce nuclear technology into Indonesia's elementary and secondary schools. These youngsters are still in their formative years and are absorbing science and technology with great attention. (authors)

  1. A model for the selective amplification of spatially coherent waves in a centrifugal compressor on the verge of rotating stall

    Science.gov (United States)

    Lawless, Patrick B.; Fleeter, Sanford

    1993-01-01

    A simple model for the stability zones of a low speed centrifugal compressor is developed, with the goal of understanding the driving mechanism for the changes in stalling behavior predicted for, and observed in, the Purdue Low Speed Centrifugal Research Compressor Facility. To this end, earlier analyses of rotating stall suppression in centrifugal compressors are presented in a reduced form that preserves the essential parameters of the model that affect the stalling behavior of the compressor. The model is then used to illuminate the relationship between compressor geometry, expected mode shape, and regions of amplification for weak waves which are indicative of the susceptibility of the system to rotating stall. The results demonstrate that increasing the stagger angle of the diffuser vanes, and consequently the diffusion path length, results in the compressor moving towards a condition where higher-order spatial modes are excited during stall initiation. Similarly, flow acceleration in the diffuser section caused by an increase in the number of diffuser vanes also results in the excitation of higher modes.

    Full Text Available During the past 100 years in densely populated south-eastern Brazil, wetlands have been severely transformed due to urbanization, agriculture and mining. The recently discovered São Paulo Marsh Antwren (Formicivora paludicola is endemic to these wetlands, and is listed as "Critically Endangered" by the IUCN. The species is only found in an area of 1.42 km2, it has a sparse and fragmented distribution, low dispersal capacity, and has probably lost around 300 km2 of habitat in the past 100 years. Furthermore, very little is known about F. paludicola natural history, and so it is difficult to construct a robust conservation plan. Using Kernel home range estimations and the Adjusted-SD/Torus Shift test (a novel tool for animal-habitat association studies, we showed that the species avoids patches of the alien invasive ginger lily (Hedychium coronarium. Given the high density of their population (3.6 mature individuals/ha, F. paludicola could thrive in relatively small areas of suitable wetlands protected from human occupation and water contamination, however special attention should be paid to biological invasions, which may represent a serious threat to the remaining populations. Protecting a few small wetlands used by F. paludicola would be an important step towards general conservation and restoration of Atlantic Forest wetlands and its endemic endangered species.

    Introduction Human injury or infection induces systemic inflammation with characteristic neuro-endocrine responses. Fluctuations in autonomic function during inflammation are reflected by beat-to-beat variation in heart rate, termed heart rate variability (HRV). In the present study, we determine threshold doses of endotoxin needed to induce observable changes in markers of systemic inflammation, we investigate whether metrics of HRV exhibit a differing threshold dose from other inflammatory markers, and we investigate the size of data sets required for meaningful use of multi-scale entropy (MSE) analysis of HRV. Methods Healthy human volunteers (n=25) were randomized to receive placebo (normal saline) or endotoxin/lipopolysaccharide (LPS): 0.1, 0.25, 0.5, 1.0, or 2.0 ng/kg administered intravenously. Vital signs were recorded every 30 minutes for 6 hours and then at 9, 12, and 24 hours after LPS. Blood samples were drawn at specific time points for cytokine measurements. HRV analysis was performed using EKG epochs of 5 minutes. MSE for HRV was calculated for all dose groups to scale factor 40. Results The lowest significant threshold dose was noted in core temperature at 0.25ng/kg. Endogenous TNF-α and IL-6 were significantly responsive at the next dosage level (0.5ng/kg) along with elevations in circulating leukocytes and heart rate. Responses were exaggerated at higher doses (1 and 2 ng/kg). Time domain and frequency domain HRV metrics similarly suggested a threshold dose, differing from placebo at 1.0 and 2.0 ng/kg, below which no clear pattern in response was evident. By applying repeated-measures ANOVA across scale factors, a significant decrease in MSE was seen at 1.0 and 2.0 ng/kg by 2 hours post exposure to LPS. While not statistically significant below 1.0 ng/kg, MSE unexpectedly decreased across all groups in an orderly dose-response pattern not seen in the other outcomes. Conclusions By usingrANOVA across scale factors, MSE can detect autonomic change after LPS challenge in a group of 25 subjects using EKG epochs of only 5 minutes and entropy analysis to scale factor of only 40, potentially facilitating MSE’s wider use as a research tool or bedside monitor. Traditional markers of inflammation generally exhibit threshold dose behavior. In contrast, MSE’s apparent continuous dose-response pattern, while not statistically verifiable in this study, suggests a potential subclinical harbinger of infectious or other insult. The possible derangement of autonomic complexity prior to or independent of the cytokine surge cannot be ruled out. Future investigation should focus on confirmation of overt inflammation following observed decreases in MSE in a clinical setting. PMID:25526373

However, the nearness between tragedy and epic, the Trojan cycle that the first Latin writers of tragedy take for themselves, and, above all, the poetics of artistic effect based on the narrative structure and the lexical and syntactic patterns show that, at least in this passage, Seneca's source is Vergil, who is also the receiver and transmitter of ancient epic and the Greek and Roman tragedy.

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid {sup 99m}Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

    The global dynamics of an SIRS model with a nonlinear incidence rate is investigated. We establish a threshold for a disease to be extinct or endemic, analyze the existence and asymptotic stability of equilibria, and verify the existence of bistable states, i.e., a stable disease free equilibrium and a stable endemic equilibrium or a stable limit cycle. In particular, we find that the model admits stability switches as a parameter changes. We also investigate the backward bifurcation, the Hopf bifurcation and Bogdanov-Takens bifurcation and obtain the Hopf bifurcation criteria and Bogdanov-Takens bifurcation curves, which are important for making strategies for controlling a disease

    In this paper, a previously developed 2-dimensional disease model is studied, which can be used for both epidemiologic modeling and in-host disease modeling. The main attention of this paper is focused on various dynamical behaviors of the system, including Hopf and generalized Hopf bifurcations which yield bistability and tristability, Bogdanov-Takens bifurcation, and homoclinic bifurcation. It is shown that the Bogdanov-Takens bifurcation and homoclinic bifurcation provide a new mechanism for generating disease recurrence, that is, cycles of remission and relapse such as the viral blips observed in HIV infection.

    Full Text Available The pavement condition index (PCI is a simple, convenient and inexpensive way to monitor the condition of the surface of roads, identify maintenance and rehabilitation (M-and-R needs as well as ensure that road maintenance budgets are spent wisely. In this research, the pavement condition was evaluated in terms of the surface distresses existing at the time of the field evaluation. The PCI procedure was used in this research because it deals with the subject of pavement distress identification most comprehensively and is based on a sound statistical technique of pavement sampling.

    Wu, Xiaoqin P.

    2011-01-01

    Research highlights: → The conditions are given such that the characteristic equation may have purely imaginary roots and double zero roots. → Purely imaginary roots lead us to study Hopf and Bautin bifurcations and to calculate the first and second Lyapunov coefficients. → Double zero roots lead us to study Bogdanov-Takens (BT) bifurcation. → Bifurcation diagrams for Bautin and BT bifurcations are obtained by using the normal form theory. - Abstract: In this paper, complete analysis is presented to study codimension-2 bifurcations for the nonlinear Kaldor model of business cycle. Sufficient conditions are given for the model to demonstrate Bautin and Bogdanov-Takens (BT) bifurcations. By computing the first and second Lyapunov coefficients and performing nonlinear transformation, the normal forms are derived to obtain the bifurcation diagrams such as Hopf, homoclinic and double limit cycle bifurcations. Some examples are given to confirm the theoretical results.

    Recently, using coordinated VLA+Chandra observations, Bogdanov et al.(2017) have uncovered a stunning anti-correlation in the LMXB state of the tMSP PSR J1023+0038. They see that radio luminosity consistently peaks during the X-ray `low' luminosity modes. Also, we have found a promising candidate tMSP, 3FGL J1544-1125(J1544) (Bogdanov and Halpern 2015; currently only tMSP candidate apart from J1023 in a persistent LMXB state). Using VLA and simultaneous Swift observations we see that it lies on the proposed tMSP track in radio vs. X-ray luminosity (L_ R/L_X) diagram. This finding strengthens its classification as a tMSP and provides an excellent opportunity to a)determine universality of radio/X-ray brightness anti-correlatio and b)understand jet/outflow formation in tMSPs.

    The dynamics of a small Prandtl number binary mixture in a laterally heated cavity is studied numerically. By combining temporal integration, steady state solving and linear stability analysis of the full PDE equations, we have been able to locate and characterize a codimension-three degenerate Takens-Bogdanov point whose unfolding describes the dynamics of the system for a certain range of Rayleigh numbers and separation ratios near S=-1.

  3. Normal forms of Hopf-zero singularity

    Science.gov (United States)

    Gazor, Majid; Mokhtari, Fahimeh

    2015-01-01

    The Lie algebra generated by Hopf-zero classical normal forms is decomposed into two versal Lie subalgebras. Some dynamical properties for each subalgebra are described; one is the set of all volume-preserving conservative systems while the other is the maximal Lie algebra of nonconservative systems. This introduces a unique conservative-nonconservative decomposition for the normal form systems. There exists a Lie-subalgebra that is Lie-isomorphic to a large family of vector fields with Bogdanov-Takens singularity. This gives rise to a conclusion that the local dynamics of formal Hopf-zero singularities is well-understood by the study of Bogdanov-Takens singularities. Despite this, the normal form computations of Bogdanov-Takens and Hopf-zero singularities are independent. Thus, by assuming a quadratic nonzero condition, complete results on the simplest Hopf-zero normal forms are obtained in terms of the conservative-nonconservative decomposition. Some practical formulas are derived and the results implemented using Maple. The method has been applied on the Rössler and Kuramoto-Sivashinsky equations to demonstrate the applicability of our results.

    Highlights: → We construct a recurrent neural network by generalizing a specific n-neuron network. → Several codimension 1 and 2 bifurcations take place in the newly constructed network. → The newly constructed network has higher capabilities to learn periodic signals. → The normal form theorem is applied to investigate dynamics of the network. → A series of bifurcation diagrams is given to support theoretical results. - Abstract: A class of recurrent neural networks is constructed by generalizing a specific class of n-neuron networks. It is shown that the newly constructed network experiences generic pitchfork and Hopf codimension one bifurcations. It is also proved that the emergence of generic Bogdanov-Takens, pitchfork-Hopf and Hopf-Hopf codimension two, and the degenerate Bogdanov-Takens bifurcation points in the parameter space is possible due to the intersections of codimension one bifurcation curves. The occurrence of bifurcations of higher codimensions significantly increases the capability of the newly constructed recurrent neural network to learn broader families of periodic signals.

  16. Bidirectional recovery patterns of Mojave Desert vegetation in an aqueduct pipeline corridor after 36 years: I. Perennial shrubs and grasses

    Science.gov (United States)

    Berry, Kristin H.; Weigand, James F.; Gowan, Timothy A.; Mack, Jeremy S.

    2015-01-01

    We studied recovery of 21 perennial plant species along a severely disturbed aqueduct corridor in a Larrea tridentata-Ambrosia dumosa plant alliance in the Mojave Desert 36 years after construction. The 97-m wide corridor contained a central dirt road and buried aqueduct pipeline. We established transects at 0 m (road verge), 20 m and 40 m into the disturbance corridor, and at 100 m in undisturbed habitat (the control). Although total numbers of shrubs per transect did not vary significantly with distance from the verge, canopy cover of shrubs, species richness, and species diversity were higher in the control than at the verge and other distances. Canopy cover of common shrubs (Ericameria nauseosa, Ambrosia salsola, A. dumosa, L. tridentata, Grayia spinosa) and perennial grasses (Elymus elymoides, Poa secunda) also varied significantly by location. Discriminant analysis clearly separated the four distances based on plant composition. Patterns of recovery were bidirectional: secondary succession from the control into the disturbance corridor and inhibition from the verge in the direction of the control. Time estimated for species composition to resemble the control is dependent on location within the disturbance corridor and could be centuries at the road verge. Our findings have applications to other deserts.

  17. Qualitative dynamical analysis of chaotic plasma perturbations model

    Science.gov (United States)

    Elsadany, A. A.; Elsonbaty, Amr; Agiza, H. N.

    2018-06-01

    In this work, an analytical framework to understand nonlinear dynamics of plasma perturbations model is introduced. In particular, we analyze the model presented by Constantinescu et al. [20] which consists of three coupled ODEs and contains three parameters. The basic dynamical properties of the system are first investigated by the ways of bifurcation diagrams, phase portraits and Lyapunov exponents. Then, the normal form technique and perturbation methods are applied so as to the different types of bifurcations that exist in the model are investigated. It is proved that pitcfork, Bogdanov-Takens, Andronov-Hopf bifurcations, degenerate Hopf and homoclinic bifurcation can occur in phase space of the model. Also, the model can exhibit quasiperiodicity and chaotic behavior. Numerical simulations confirm our theoretical analytical results.

  18. Synchronization scenarios in the Winfree model of coupled oscillators

    Science.gov (United States)

    Gallego, Rafael; Montbrió, Ernest; Pazó, Diego

    2017-10-01

    Fifty years ago Arthur Winfree proposed a deeply influential mean-field model for the collective synchronization of large populations of phase oscillators. Here we provide a detailed analysis of the model for some special, analytically tractable cases. Adopting the thermodynamic limit, we derive an ordinary differential equation that exactly describes the temporal evolution of the macroscopic variables in the Ott-Antonsen invariant manifold. The low-dimensional model is then thoroughly investigated for a variety of pulse types and sinusoidal phase response curves (PRCs). Two structurally different synchronization scenarios are found, which are linked via the mutation of a Bogdanov-Takens point. From our results, we infer a general rule of thumb relating pulse shape and PRC offset with each scenario. Finally, we compare the exact synchronization threshold with the prediction of the averaging approximation given by the Kuramoto-Sakaguchi model. At the leading order, the discrepancy appears to behave as an odd function of the PRC offset.

  19. Advance elements of optoisolation circuits nonlinearity applications in engineering

    CERN Document Server

    Aluf, Ofer

    2017-01-01

    This book on advanced optoisolation circuits for nonlinearity applications in engineering addresses two separate engineering and scientific areas, and presents advanced analysis methods for optoisolation circuits that cover a broad range of engineering applications. The book analyzes optoisolation circuits as linear and nonlinear dynamical systems and their limit cycles, bifurcation, and limit cycle stability by using Floquet theory. Further, it discusses a broad range of bifurcations related to optoisolation systems: cusp-catastrophe, Bautin bifurcation, Andronov-Hopf bifurcation, Bogdanov-Takens (BT) bifurcation, fold Hopf bifurcation, Hopf-Hopf bifurcation, Torus bifurcation (Neimark-Sacker bifurcation), and Saddle-loop or Homoclinic bifurcation. Floquet theory helps as to analyze advance optoisolation systems. Floquet theory is the study of the stability of linear periodic systems in continuous time. Another way to describe Floquet theory, it is the study of linear systems of differential equations with p...

  20. Bifurcation Behavior Analysis in a Predator-Prey Model

    Directory of Open Access Journals (Sweden)

    Nan Wang

    2016-01-01

    Full Text Available A predator-prey model is studied mathematically and numerically. The aim is to explore how some key factors influence dynamic evolutionary mechanism of steady conversion and bifurcation behavior in predator-prey model. The theoretical works have been pursuing the investigation of the existence and stability of the equilibria, as well as the occurrence of bifurcation behaviors (transcritical bifurcation, saddle-node bifurcation, and Hopf bifurcation, which can deduce a standard parameter controlled relationship and in turn provide a theoretical basis for the numerical simulation. Numerical analysis ensures reliability of the theoretical results and illustrates that three stable equilibria will arise simultaneously in the model. It testifies the existence of Bogdanov-Takens bifurcation, too. It should also be stressed that the dynamic evolutionary mechanism of steady conversion and bifurcation behavior mainly depend on a specific key parameter. In a word, all these results are expected to be of use in the study of the dynamic complexity of ecosystems.

  1. Social mobility in socialist Serbia: A revisionist approach

    Directory of Open Access Journals (Sweden)

    Antonić Slobodan

    2013-01-01

    Full Text Available This paper starts from the findings of the latest study of social structure in Serbia (2012, which show a significant reduction of vertical social mobility, especially for further inter-stratum distance. In light of these data, the author considers that we have to re-examine earlier, very biting evaluation of some Serbian sociologists concerning 'closeness' for mobility of the society in socialist Serbia. The author analyzes and re-evaluated findings of earlier research (Janićijević, 1970; Flere and Đurđev, 1982/3; Bogdanovic, 1986; 1988; Vukovic, 1989. He concludes that very brisk evaluation of mobility in the Serbian society during socialism is a consequence of schematic interpretation of these findings with Yasuda 's index.

  2. Successful Self-Expandable Metallic Stent Placement for a Case of Distal Rectal Stenosis due to Gastric Cancer Metastasis

    Directory of Open Access Journals (Sweden)

    Takuya Okugawa

    2013-05-01

    Full Text Available A 47-year-old woman was diagnosed as having advanced gastric cancer with malignant ascites. Despite chemotherapy, recurrent peritoneal dissemination was seen 1.5 years after operation. A computed tomography scan revealed rectal stenosis due to Schnitzler's metastasis. When the distance from the distal end of the obstruction to the anal verge is less than 5 cm, stent replacement has been said to be contraindicated due to the development of anal pain and foreign body sensation. Although the distance from the distal end of the obstruction to the anal verge was 4 cm in this case, a WallFlex™ colonic stent could be placed. She stayed home, and luminal patency remained until she died 270 days after stent insertion. This report demonstrates that rectal obstruction located less than 5 cm from the anal verge due to Schnitzler's metastasis could be treated by stenting without any symptomatic or technical complications.

    2001-01-01

    A microminiature timer having an optical readout is disclosed. The timer can be formed by surface micromachining or LIGA processes on a silicon substrate. The timer includes an integral motor (e.g. an electrostatic motor) that can intermittently wind a mainspring to store mechanical energy for driving a train of meshed timing gears at a rate that is regulated by a verge escapement. Each timing gear contains an optical encoder that can be read out with one or more light beams (e.g. from a laser or light-emitting diode) to recover timing information. In the event that electrical power to the timer is temporarily interrupted, the mechanical clock formed by the meshed timing gears and verge escapement can continue to operate, generating accurate timing information that can be read out when the power is restored.

    1996-03-01

    Interpretation of reflection seismic data from the southwestern Alberta Foothills near the Crowsnest Deflection provided insight into the structural relationship between the triangle zone and the foreland basin. Six seismic lines were interpreted which show autochtonous Paleozoic rocks overlain by thrust sheets of upper Mesozoic and Tertiary strata. The overall structural geometry consists of an allochtonous wedge with east-verging shingles that are sandwiched between undeformed Paleozoic strata and the Alberta Syncline. The Big Coulee Fault, which rides within the Bearpaw Formation, represents the boundary between the east and west-verging structures and is the main upper detachment of the triangle zone. A lateral ramp occurs in the lower detachment which is evidence for southward thickening of the allochtonous wedge. 24 refs., 2 tabs., 8 figs.

  1. Calculations with the quasirelativistic local-spin-density-functional theory for high-Z atoms

    International Nuclear Information System (INIS)

    Guo, Y.; Whitehead, M.A.

    1988-01-01

    The generalized-exchange local-spin-density-functional theory (LSD-GX) with relativistic corrections of the mass velocity and Darwin terms has been used to calculate statistical total energies for the neutral atoms, the positive ions, and the negative ions for high-Z elements. The effect of the correlation and relaxation correction on the statistical total energy is discussed. Comparing the calculated results for the ionization potentials and electron affinities for the atoms (atomic number Z from 37 to 56 and 72 to 80) with experiment, shows that for the atoms rubidium to barium both the LSD-GX and the quasirelativistic LSD-GX, with self-interaction correction, Gopinathan, Whitehead, and Bogdanovic's Fermi-hole parameters [Phys. Rev. A 14, 1 (1976)], and Vosko, Wilk, and Nusair's correlation correction [Can. J. Phys. 58, 1200 (1980)], are very good methods for calculating ionization potentials and electron affinities. For the atoms hafnium to mercury the relativistic effect has to be considered

  2. Stability diagram for the forced Kuramoto model.

    Science.gov (United States)

    Childs, Lauren M; Strogatz, Steven H

    2008-12-01

    We analyze the periodically forced Kuramoto model. This system consists of an infinite population of phase oscillators with random intrinsic frequencies, global sinusoidal coupling, and external sinusoidal forcing. It represents an idealization of many phenomena in physics, chemistry, and biology in which mutual synchronization competes with forced synchronization. In other words, the oscillators in the population try to synchronize with one another while also trying to lock onto an external drive. Previous work on the forced Kuramoto model uncovered two main types of attractors, called forced entrainment and mutual entrainment, but the details of the bifurcations between them were unclear. Here we present a complete bifurcation analysis of the model for a special case in which the infinite-dimensional dynamics collapse to a two-dimensional system. Exact results are obtained for the locations of Hopf, saddle-node, and Takens-Bogdanov bifurcations. The resulting stability diagram bears a striking resemblance to that for the weakly nonlinear forced van der Pol oscillator.

  3. Consolidation and restoration of memory traces in working memory.

    Science.gov (United States)

    De Schrijver, Sébastien; Barrouillet, Pierre

    2017-10-01

    Consolidation is the process through which ephemeral sensory traces are transformed into more stable short-term memory traces. It has been shown that consolidation plays a crucial role in working memory (WM) performance, by strengthening memory traces that then better resist interference and decay. In a recent study, Bayliss, Bogdanovs, and Jarrold (Journal of Memory and Language, 81, 34-50, 2015) argued that this process is separate from the processes known to restore WM traces after degradation, such as attentional refreshing and verbal rehearsal. In the present study, we investigated the relationship between the two types of processes in the context of WM span tasks. Participants were presented with series of letters for serial recall, each letter being followed by four digits for parity judgment. Consolidation opportunity was manipulated by varying the delay between each letter and the first digit to be processed, while opportunities for restoration were manipulated by varying the pace at which the parity task had to be performed (i.e., its cognitive load, or CL). Increasing the time available for either consolidation or restoration resulted in higher WM spans, with some substitutability between the two processes. Accordingly, when consolidation time was added to restoration time in the calculation of CL, the new resulting index, called extended CL, proved a very good predictor of recall performance, a finding also observed when verbal rehearsal was prevented by articulatory suppression. This substitutability between consolidation and restoration suggests that both processes may rely on the same mechanisms.

  5. Oscillations in the bistable regime of neuronal networks.

    Science.gov (United States)

    Roxin, Alex; Compte, Albert

    2016-07-01

    Bistability between attracting fixed points in neuronal networks has been hypothesized to underlie persistent activity observed in several cortical areas during working memory tasks. In network models this kind of bistability arises due to strong recurrent excitation, sufficient to generate a state of high activity created in a saddle-node (SN) bifurcation. On the other hand, canonical network models of excitatory and inhibitory neurons (E-I networks) robustly produce oscillatory states via a Hopf (H) bifurcation due to the E-I loop. This mechanism for generating oscillations has been invoked to explain the emergence of brain rhythms in the β to γ bands. Although both bistability and oscillatory activity have been intensively studied in network models, there has not been much focus on the coincidence of the two. Here we show that when oscillations emerge in E-I networks in the bistable regime, their phenomenology can be explained to a large extent by considering coincident SN and H bifurcations, known as a codimension two Takens-Bogdanov bifurcation. In particular, we find that such oscillations are not composed of a stable limit cycle, but rather are due to noise-driven oscillatory fluctuations. Furthermore, oscillations in the bistable regime can, in principle, have arbitrarily low frequency.

    In addition to the process of photosynthesis, the bee community is the main source of energy in food production, honey-plants used by game and people in the hunting grounds ecosystem. It is a well-known fact that thousands of plant species depend on the presence of bee communities (pollination, fertilization). In this paper we studied the presence of the bee community in the hunting grounds of Croatian Forests, and their influence on the number of game (wild pigs), as well as the quality of honey, honey plants in the hunting grounds used by people and game. We established the total number of game (wild boars). The honey quality parameters were determined using the Harmonised methods of the European Honey (Bogdanov et al., 1997) and the pollen analysis by were conducted according to Harmonised methods of melissopalynology (Von der Ohe et al., 2004). Research results indicate that the presence of the bee community influences the number of wild boars from 3-18%, and the quality of honey is in line with the European and world standards. The SAS/STAT package was used for the statistical analysis (SAS Institute Inc., 2000). The significance of the differences among the groups was determined by Duncan test.

Previous studies have described north-verging thrust faults and some strike-slip faults, reflected in the northward-convex geomorphologic and structural grain of the Pamir Mountains. However, this structural analysis suggests that contemporary tectonics are changing the style of deformation from north-verging thrusts formed during the initial contraction of the Himalayan orogeny to south-verging thrusts and a series of northwest-trending, dextral strike-slip faults in the modern transpressional regime. These northwest-trending fault zones are linked to the major right-lateral Karakoram fault, located to the east, as synthetic, conjugate shears that form a right-stepping en echelon pattern. Northwest-trending lineaments with dextral displacements extend continuously westward across the Hindu Kush-Pamir region indicating a pattern of systematic shearing of multiple blocks to the northwest as the deformation effects from Indian plate collision expands to the north-northwest. Locally, east-northeast- and northwest-trending faults display sinistral and dextral displacement, respectively, yielding conjugate shear pairs developed in a northwest-southeast compressional stress field. Geodetic measurements and focal mechanisms from historical seismicity support these surficial, tectono-morphic observations. The conjugate shear pairs may be structurally linked subsidiary faults and co-seismically slip during single large magnitude (> M7) earthquakes that occur on major south-verging thrust faults. This kinematic model provides a potential context for prehistoric, historic, and future patterns of faulting and earthquakes.

However, inadequate planning has exposed a vacuity, as the educational authorities failed to develop a workforce before creating the specialized department. As a result, this vacuum is on the verge of being impinged by pharmacy professionals specialized in entirely different domains which would be detrimental to the future prospects of the development of pharmacy practice in Pakistan.

  14. Switchgrass (Panicum virgatum L. Genotypes Differ between Coastal Sites and Inland Road Corridors in the Northeastern US.

    Directory of Open Access Journals (Sweden)

    Geoffrey Ecker

    Full Text Available Switchgrass (Panicum virgatum L. is a North American grass that exhibits vast genetic diversity across its geographic range. In the Northeastern US, local switchgrass populations were restricted to a narrow coastal zone before European settlement, but current populations inhabit inland road verges raising questions about their origin and genetics. These questions are important because switchgrass lines with novel traits are being cultivated as a biofuel feedstock, and gene flow could impact the genetic integrity and distribution of local populations. This study was designed to determine if: 1 switchgrass plants collected in the Long Island Sound Coastal Lowland coastal Level IV ecoregion represented local populations, and 2 switchgrass plants collected from road verges in the adjacent inland regions were most closely related to local coastal populations or switchgrass from other geographic regions. The study used 18 microsatellite markers to infer the genetic relationships between 122 collected switchgrass plants and a reference dataset consisting of 28 cultivars representing ecotypes, ploidy levels, and lineages from North America. Results showed that 84% of 88 plants collected in the coastal plants were most closely aligned with the Lowland tetraploid genetic pool. Among this group, 61 coastal plants were similar to, but distinct from, all Lowland tetraploid cultivars in the reference dataset leading to the designation of a genetic sub-population called the Southern New England Lowland Tetraploids. In contrast, 67% of 34 plants collected in road verges in the inland ecoregions were most similar to two Upland octoploid cultivars; only 24% of roadside plants were Lowland tetraploid. These results suggest that cryptic, non-local genotypes exist in road verges and that gene flow from biofuels plantations could contribute to further changes in switchgrass population genetics in the Northeast.

    Full Text Available The 26 sample sites in 7 study plots adjacent to asphalt road and earth road in coastal wetland in the Yellow River Delta were selected to quantify plant diversity using quadrat sampling method in plant bloom phase of July and August 2012. The indice of βT and Jaccard’s coefficient were applied to evaluate the species diversity. The results showed that the plant diversities and alien plants were high in the range of 0–20 m to the road verge. There were more exotics and halophytes in plots of asphalt roadside than that of earth roadside. However, proportion of halophytes in habitats of asphalt roadsides was lower than that of earth roadside. By comparing β-diversity, there were more common species in the asphalt roadsides than that in the earth roadsides. The similarity of plant communities in studied plots of asphalt roadsides and earth roadsides increased with increasing the distance to road verge. The effect range of roads for plant diversity in study region was about 20 m to road verge. Our results indicate that the construction and maintenance of roads in wetland could increase the plant species diversities of communities and risk of alien species invasion.

    Full Text Available In this essay written in 2004, Françoise Vergès and Carpanin Marimoutou explore the ways in which processes and practices of creolization occurred in Réunion Island. They argue that creolization must be analyzed within the historical, political and cultural context in which they emerge. Vergès and Marimoutou reflect on these processes -- frictions, conflicts, and exchanges among slaves, settlers, migrants, and indentured workers from Madagascar, Mozambique, Gujarat, Bengal, France, Tamil Nadu, Southern China, Malaysia, Vietnam..., who were brought or came on the uninhabited island, colonized by the French in the 17th century. The authors also looked at the post-colonial moment, the French policies of assimilation and repression in the 1960s-1970s. For them, vernacular cultural practices and memories of struggle continue to work as counter strategies against local and national reactionary politics. In their conclusion, Vergès and Marimoutou look at the current form of globalization and its consequences on processes of creolization.

  1. Paving the Way for Invasive Species: Road Type and the Spread of Common Ragweed ( Ambrosia artemisiifolia)

    2011-09-01

    Roads function as prime habitats and corridors for invasive plant species. Yet despite the diversity of road types, there is little research on the influence of these types on the spread of invaders. Common ragweed ( Ambrosia artemisiifolia), a plant producing large amounts of allergenic pollen, was selected as a species model for examining the impact of road type on the spread of invasive plants. We examined this relationship in an agricultural region of Quebec, Canada. We mapped plant distribution along different road types, and constructed a model of species presence. Common ragweed was found in almost all sampling sites located along regional (97%) and local paved (81%) roads. However, verges of unpaved local roads were rarely (13%) colonized by the plant. A model (53% of variance explained), constructed with only four variables (paved regional roads, paved local roads, recently mown road verges, forest cover), correctly predicted (success rate: 89%) the spatial distribution of common ragweed. Results support the hypothesis that attributes associated with paved roads strongly favour the spread of an opportunistic invasive plant species. Specifically, larger verges and greater disturbance associated with higher traffic volume create propitious conditions for common ragweed. To date, emphasis has been placed on controlling the plant in agricultural fields, even though roadsides are probably a much larger seed source. Strategies for controlling the weed along roads have only focused on major highways, even though the considerable populations along local roads also contribute to the production of pollen. Management prioritizations developed to control common ragweed are thus questionable.

    The Kibaran aged Irumide belt and the Pan African aged Lufilian arc intersect in central Zambia. The Irumide belt is a thrust belt comprising northwesterly verging structures in the north, upright structures in the central zone and southeasterly verging structures in the south. Tectonic transport, as deduced from regional stretching lineations, changes across the central upright zone. To the north of this zone, movement is to the northwest; to the south of the zone, movement is to the southeast. This divergence of structures about a central upright zone is recognized throughout the belt. The Lufilian arc comprises a northeasterly verging thrust belt involving large basement thrust sheets forming domal culimations throughoutregion. These thrusts climb up-section towards the northeast and have telescoped the Katangan stratigraphy. In the Copperbelt area of the arc, the Irumide and Lufilian structures are separated by a marked unconformity. However in the Mubalashi area, south of the Copperbelt, there is aa coincidence of strike of Lufilian and Irumide structures which, in the past, has made their separation difficult. The structures can be separated on the basis of stretching lineations associated with the deformation. In the ENE striking Lufilian structures stretching lineations are seen to be sub-horizontal, suggesting a lateral ramp relationship to the main Lufilian deformation. Similar striking Irumide structures have a steeply plunging down dip lineation. The intersection of these two belts represents the junction of two different tectonic systems operating in Africa during the Late Proterozoic.

    Alkali metal aluminohydrides have high potential as solid hydrogen storage materials. They have been known for their irreversible dehydrogenation process below 100 atm until Bogdanovic et al [1, 2] succeeded in the re-hydrogenation of NaAlH4 below 70 atm. They achieved 4 wt.% H2 reversible capacity by doping NaAlH4 with Ti and/or Fe organo-metalic compounds as catalysts. This suggests that other alkali and, possibly alkaline earth metal aluminohydrides can be used for reversible hydrogen storage when modified by proper dopants. In this research, Zr27Ti9Ni38V5Mn16Cr5, LaNi4.85Sn0.15, Al3Ti, and PdCl2 were combined , LaNi4.85Sn0.15, Al3Ti, and PdCl2 were combined with LiAlH4 by ball-milling to study whether or not LiAlH4 is capable to both absorb and desorb hydrogen near ambient conditions. X-ray powder diffraction, differential thermal analysis, and scanning electron microscopy were employed for sample characterizations. All four compounds worked as catalysts in the dehydrogenation reactions of both LiAlH4 and Li3AlH6 by inducing the decomposition at lower temperature. However, none of them was applicable as catalyst in the reverse hydrogenation reaction at low to moderate hydrogen pressure.

In a majority of the cases, HCC is associated with the underlying chronic liver disease, and it is diagnosed in advanced stage of disease when curative treatment options are not applicable. Sorafenib is a treatment of choice for patients with performance status 1 or 2 and/or macrovascular invasion or extrahepatic spread, and regorafenib is the only systemic treatment found to provide survival benefit in HCC patients progressing on sorafenib treatment. Other drugs tested in different trials failed to demonstrate any benefit. Disappointing results of numerous trials testing the efficacy of various drugs indicate that HCC has low sensitivity to chemotherapy that is in great part caused by multidrug resistance. Immunotherapy for HCC is a new challenging treatment option and involves immune checkpoint inhibitors/antibody-based therapy and peptide-based vaccines. Another challenging approach is microRNA-based therapy that involves two strategies. The first aims to inhibit oncogenic miRNAs by using miRNA antagonists and the second strategy is miRNA replacement, which involves the reintroduction of a tumor-suppressor miRNA mimetic to restore a loss of function.

Pokrovsky and I. Skvortsov-Stepanov in 1922– 1923. In the first part of the article the author examines the political, intellectual and social-biographical contexts of the polemics. Second part is devoted to explication of the main points of conceptions of authors under discussion in religious studies: their understanding of science, their interpretations of «historical materialism», their understanding of mutual relations of practice of «struggle against religion», anti-religious propaganda and scientific studying of religion in the context of struggle of classes, their decisions of questions of origin of religion, basic moments of its history. The third part examines the polemics itself: its total movement, basic ideas, argumentation of participants, their systems of values, varieties of Marxist approach to the study of religion, understanding of history of religion, its relation to its economic basis, their attitude to ideas of A. Bogdanov, A. Lunacharsky and other thinkers. In conclusion the author make a number of preliminary findings for discussion on significance and meaning of the polemics in question, its «ethos», its place in the history of soviet «scientific atheism», its role in development of psychology of religion in Russia.

    Full Text Available This is the first study of the role Soviet diplomats and representatives of the Communist International (Comintern played in the Soviet-Tuvan relations during the first decade after the emergence of the young Tuvan state – People’s Republic of Tuva (1920s. From representing the interests of a small military mission, the Soviet diplomatic office in Tuva evolved into a full-scale embassy of the Soviet state. Its history clearly falls into two stages: from early 1920s to 1927 Soviet mission members largely abstained from interfering into PRT’s internal issues, but subsequently they started actively promoting the left wing of Tuvan People Revolutionary Party, which contributed to its accession to power. The Soviet state began to act as PRT’s patron on the international arena. This policy of support and custody was in accordance with Article 2 of PRT’s constitution. Using documentary sources, this article traces the appointments and transfers of a number of Soviet diplomatic officers and consuls (F.G. Falsky (Falkovsky, I.A. Chichayev, F.F. Razumov, A.G. Starkov, as well as Comintern representatives (I.G. Safyanov, B. Tsivenzhapov, V. Borovikov, A.M. Amur-Sanan, S.A. Natsov, V. Machavariani, V.A. Bogdanov. In the duopoly of consuls and Comintern representatives, the former dominated at the earlier stages, but after the defeat of Chinese communists in 1927 the Soviet leaders thought that Socialist transformations in Mongolia in Tuva should be sped up. The article makes use of archival sources from the State Archive of the Republic of Tuva, Russian State Archive of Socio-Political History (RGASPI, and the Research archive of Tuva Institute for Humanities and Applied Socioeconomic Studies.

    Thermodynamics and kinetics of the reversible dissociation of metal-doped NaAlH{sub 4} as a hydrogen (or heat) storage system have been investigated in some detail. The experimentally determined enthalpies for the first (3.7 wt% of H) and the second dissociation step of Ti-doped NaAlH{sub 4} (3.0 wt% H) of 37 and 47 kJ/mol are in accordance with low and medium temperature reversible metal hydride systems, respectively. Through variation of NaAlH{sub 4} particle sizes, catalysts (dopants) and doping procedures, kinetics as well as the cyclization stability within cycle tests have been substantially improved with respect to the previous status [B. Bogdanovic, M. Schwickardi (1997)]. In particular, using combinations of Ti and Fe compounds as dopants, a cooperative (synergistic) catalytic effect of the metals Ti and Fe in enhancing rates of both de- and rehydrogenation of Ti/Fe-doped NaAlH{sub 4} within cycle tests, reaching a constant storage capacity of {proportional_to}4 wt% H{sub 2}, has been demonstrated. By means of {sup 57}Fe Moessbauer spectroscopy of the Ti/Fe-doped NaAlH{sub 4} before and throughout a cycle test, it has been ascertained that (1) during the doping procedure, nanosize metallic Fe particles are formed from the doping agent Fe(OEt){sub 2} and (2) already after the first dehydrogenation, the nanosize Fe particles with NaAlH{sub 4} present are probably transformed into an Fe-Al-alloy which throughout the cycle test remains practically unchanged.

    Mariano D. Perelman

    2010-01-01

    Full Text Available Durante la década de 1990 y los primeros años de la siguiente, en las calles de la ciudad de Buenos Aires comenzaron a aparecer miles de personas, que luego de haber perdido el empleo, recurrieron a hurgar en las bolsas de residuos en busca de materiales que pudieran ser vendidos o reutilizados. Esta actividad se ha denominado cirujeo. En este artículo me interesa analizar la manera en la que viven la actividad las personas que se iniciaron en la recolección informal a mediados de los noventa. Demostraré en este trabajo que esa vivencia no se sustenta en una relación lineal entre estigma y vergüenza, sino que es más compleja y contradictoria. Al tiempo que los cirujas quieren pasar desapercibidos en ciertos ámbitos y sienten vergüenza por las tareas que realizan, deben visibilizarse y generar relaciones de confianza –lo que supone reconocimiento mutuo- con quienes les proveen la basura. Para desnaturalizar esa relación entre estigma, vergüenza y cirujeo –que suele pensarse de manera transparente- y llegar a dar cuenta del carácter a la vez colectivo, singular y experiencialmente vivido de la misma trabajaré a partir de un análisis complejo de las trayectorias de las personas, los discursos hegemónicos en torno al trabajo, las proyecciones y diferencias entre lo que los cartoneros son y lo que querrían ser. En general, lo que me interesa argumentar es que no sólo la experiencia subjetiva de la desigualdad colabora en la explicación de la acción de los sujetos, sino que también determina la forma en la que la actividad se estructura.

    Full Text Available En el presente estudio, se exploran las atribuciones de emociones morales de los adolescentes, ante una historia de maltrato entre iguales en el contexto escolar. Con ese objetivo, les preguntamos a cerca de los sentimientos de culpa, vergüenza, orgullo e indiferencia de agresores, víctimas y espectadores y les pedimos que justificaran la atribución de los mismos. Procuramos además saber si en términos de su experiencia personal se identifican o se desvinculan de cualquiera de ellos. Participaron un total de 1.237 preadolescentes y adolescentes españoles y portugueses de edades comprendidas entre los 11 y los 16 años. Para el estudio diseñamos el cuestionario SCAN-Bullying 2005 con soporte gráfico (conjunto de viñetas que representan una historia típica de maltrato entre iguales en el contexto escolar. Los resultados muestran un patrón emocional diferente en función del rol: orgullo e indiferencia fueron las emociones más atribuidas a los agresores, inversamente la vergüenza fue la emoción más atribuida a la víctima, mientras que la indiferencia, vergüenza y culpa se atribuyeron en porcentajes muy semejantes a los espectadores. La investigación se inscribe en el cuadro teórico de estudios anteriores que analizan el fenómeno del agresor feliz y de la desvinculación moral, y a la luz de este encuadramiento teórico, procuraremos discutir los resultados.

    Two decades after Iran's Islamic revolution, science in this politically isolated but oil-rich nation may be on the verge of resurgence. The nation's reform-minded president, Mohammad Khatami, and his allies are promising more money for R&D, reorganizing universities to beef up graduate education and research, and cracking open the door to closer cooperation with scientists abroad, including those in the United States. But Iran's government is walking a tightrope between hard-liners on the right who oppose reforms and liberal university students eager for change.

    The equation-of-motion coupled cluster (EOM-CC) framework has been used for deriving a novel series of perturbative corrections to the coupled cluster singles and doubles energy that formally con- verges towards the full configuration interaction energy limit. The series is based on a Møller-Ples......-Plesset partitioning of the Hamiltonian and thus size extensive at any order in the perturbation, thereby rem- edying the major deficiency inherent to previous perturbation series based on the EOM-CC ansatz. © 2014 AIP Publishing LLC.

    Metallic foams are on the verge of being used in industrial applications. However, the mechanism of foam creation, especially the early stages, are still unexplored. Ultra small-angle neutron scattering (USANS), performed with the double-crystal diffractometer (DCD) at the Geesthacht Neutron Facility (GeNF), is a promising method for obtaining a three-dimensional average of a pore size distribution in a wide size range from about 100 nm to about 20 mu m. Analysis of the neutron scattering curves yielded pore size distributions which conformed with the results obtained by microscopy. (orig.)

    2018-06-01

    Given his lifelong battle against one-sidedness Jung's persistent prioritising of the 'inner life' over the 'outer' can seem problematic. The question is raised as to whether an approach that seems to verge uncomfortably close to solipsism can sometimes render Jung blind to the intuition that psychic life is constituted by an on-going interplay between inner and outer, self and other (an intuition that he himself sometimes articulated so brilliantly). The 'ambiguation' of Jung's work offers an opportunity to confront this problem by utilising a critical dynamic that is consistent with Jung's psychological insights. © 2018, The Society of Analytical Psychology.

    This paper describes a major new technology supporting the further evolution of accelerators: superconducting radio frequency (SRF) technology, which is today on the verge of large-scale application in accelerators. Originally foreseen in the early 1960s as a promising technology, SRF only recently has overcome several technological and practical hurdles. SRF accelerating structures promise low rf losses and high gradients under cw operation. High-quality, intense cw beams can be accelerated without risk of melting the structure and without requiring enormous amounts of input rf power

    Full Text Available We propose a model of two-dimensional dilaton gravity with a boundary. In the bulk our model coincides with the classically integrable CGHS model; the dynamical boundary cuts of the CGHS strong-coupling region. As a result, classical dynamics in our model reminds that in the spherically-symmetric gravity: wave packets of matter fields either reflect from the boundary or form black holes. We find large integrable sector of multisoliton solutions in this model. At the same time, we argue that the model is globally non-integrable because solutions at the verge of black hole formation display chaotic properties.

    Full Text Available The Arieseni Nappe was the single tectonic unit of the Biharia Nappe System involving unmetamorphosed, red Permian and metamorphosed, green Permian deposits. Deformational, microscopic and x-Ray diffraction studies, suggest a tectonic relationship between the two sequences. Consequently, the red Permian deposits have been attributed to the Moma Nappe, and the green Permian rocks to the Poiana Nappe. Thus, the Arieseni Nappe disappeared. The thrust between the red Permian and the green Permian deposits realized later during the emplacement of Apusenides, due to an east-verging movement.

    We performed colonic J-pouch anal anastomosis in 61 patients with rectal cancer located <4 cm from the anal verge. Surgical and oncological results were evaluated in multimodality therapy for advanced rectal cancer. According to Wexner's score, 7% of patients were fully continent, 71% had acceptable function with minor continence problems, and 22% were incontinent. No patients required intermittent self-catheterization during follow-up. After a median follow-up of 49 months, there was only 1 case of local recurrence after surgery. Our surgical approach irrespective of internal sphincter resection produces satisfactory functional and oncological results in multimodality therapy using preoperative chemoradiotherapy for lower rectal cancer.

    2000-10-01

    The red cockaded woodpecker has been intensively studied since 1985 when the population was on the verge of extinction. The population decline is primarily the result of timber harvesting prior to 1950 and restricted burning. Construction of artificial cavities, translocations, competitor control, and removal of hardwood mid-story has provided suitable habitat. Since 1985, the population has increased from 4 to 99 birds. A GIS model is being developed to simulate the development of habitat at SRS in relation to management and existing vegetation.

    The detection of gravitational waves is, nowadays, technologically possible. The Virgo project, proposed by a French-Italian collaboration, is now on the verge of being fully approved and funded. The goal of the Virgo project is, first, to detect gravitational waves. The next will be to perform, in conjunction with other similar detectors, more precise measurements (i.e. the spin of the graviton) and start gravitational wave astrophysical observations. The method is proposed to use a large Michelson interferometer as a detector. The main motivations, characteristics and expected sensitivity of this project are described. (R.P.) 14 refs., 6 figs

    A homogeneous colossal magnetoresistance (CMR) effect at low temperatures has been found in a thin-film perovskite manganite Pr0.5Sr0.5MnO3. The transition is driven not by the spin alignment as in usual CMR in bulk samples but by the localization-delocalization transition switched by the change in the effective dimensionality. Two-dimensional (x2-y2)-orbital ordering enhanced by the substrate strain is essential for the stabilization of the insulating localized state, which is on the verge of the first-order transition to the three-dimensional metallic ferromangetic state.

  12. Extensional collapse in the Neoproterozoic Araçuaí orogen, eastern Brazil: a setting for reactivation of asymmetric crenulation cleavage

    Science.gov (United States)

    Marshak, Stephen; Alkmim, Fernando F.; Whittington, Alan; Pedrosa-Soares, Antônio Carlos

    2006-01-01

    The Araçuaí orogen of eastern Brazil is one of many Brasiliano/Pan African orogens formed during the Neoproterozoic assembly of Gondwana. Its western edge, bordering the São Francisco craton, is the Serra do Espinhaço fold-thrust belt, in which top-up-to-the-west (reverse-sense) faults, west-verging folds (F 1), and east-dipping spaced to phyllitic cleavage (S 1) developed. We have found that the kinematics of deformation changes markedly at the hinterland margin of this fold-thrust belt. Here, beneath a plateau known as the Chapada Acauã, metadiamictite and fine-grained pelitic schist comprise an east-dipping belt that contains an assemblage of structures indicative of top-down-to-the-east (normal-sense) shear. This assemblage includes a cascade of F 2 folds that refold F 1 folds and verge down the dip of the belt's enveloping surfaces, vertical tension gashes, and top-down-to-the-east rotated clasts. Based on the presence of these structures, we propose that the plateau exposes a regional-scale normal-sense shear zone, here called the Chapada Acauã shear zone (CASZ). Because F 2 folds refold F 1 folds, normal-sense shear in the CASZ occurred subsequent to initial west-verging thrusting. Considering this timing of motion in the CASZ, we suggest that the zone accommodated displacement of the internal zone of the Araçuaí orogen down, relative to its foreland fold-thrust belt, and thus played a role in extensional collapse of the orogen. The CASZ trends parallel to preserved thrusts to the west, and thus may represent an inverted thrust fault. Notably, throughout the CASZ, S 1 schistosity has been overprinted by a pervasive, west-dipping asymmetric crenulation cleavage (S 2). The sigmoid shape of S 1 surfaces in S 2 microlithons require that slip on each S 2 surface was top-down-to-the-west. S 2 cleavage is axial-planar to the down-dip verging F 2 folds. Based on its geometry, we suggest that S 2 cleavage initiated either as an antithetic extensional

    Purpose: To determine the sites of local recurrence after total mesorectal excision for rectal cancer in an effort to optimize the radiation target. Methods and Materials: A total of 155 patients with recurrence after abdominal resection for rectal cancer were identified from a population-based consecutive cohort of 2,315 patients who had undergone surgery by surgeons trained in the total mesorectal excision procedure. A total of 99 cross-sectional imaging studies were retrieved and re-examined by one radiologist. The clinical records were examined for the remaining patients. Results: Evidence of residual mesorectal fat was identified in 50 of the 99 patients. In 83 patients, local recurrence was identified on the imaging studies. All recurrences were within the irradiated volume if the patients had undergone preoperative radiotherapy or within the same volume if they had not. The site of recurrence was in the lower 75% of the pelvis, anatomically below the S1-S2 interspace for all patients. Only 5 of the 44 recurrences in patients with primary tumors >5 cm from the anal verge were in the lowest 20% of the pelvis. Six recurrences involved the lateral lymph nodes. Conclusion: These data suggest that a lowering of the upper limit of the clinical target volume could be introduced. The anal sphincter complex with surrounding tissue could also be excluded in patients with primary tumors >5 cm from the anal verge

    The Energy Sciences Network (ESnet) is the primary provider of network connectivity for the US Department of Energy Office of Science, the single largest supporter of basic research in the physical sciences in the United States. In support of the Office of Science programs, ESnet regularly updates and refreshes its understanding of the networking requirements of the instruments, facilities, scientists, and science programs that it serves. This focus has helped ESnet to be a highly successful enabler of scientific discovery for over 20 years. In April 2010 ESnet and the Office of Biological and Environmental Research, of the DOE Office of Science, organized a workshop to characterize the networking requirements of the science programs funded by BER. The requirements identified at the workshop are summarized and described in more detail in the case studies and the Findings section. A number of common themes emerged from the case studies and workshop discussions. One is that BER science, like many other disciplines, is becoming more and more distributed and collaborative in nature. Another common theme is that data set sizes are exploding. Climate Science in particular is on the verge of needing to manage exabytes of data, and Genomics is on the verge of a huge paradigm shift in the number of sites with sequencers and the amount of sequencer data being generated.

    To evaluate the feasibility and safety of nickel-titanium compression anastomosis ring (CAR27) in colorectal anastomosis after low anterior rectal resection in animal models. End-to-end colorectal anastomosis was performed using CAR27 in 6 experimental pigs after resection of the middle and lower third of the rectum. The animals were observed postoperatively for up to 56 days. Five pigs were sacrificed at day 14 and the other at day 56. Distance from anal verge to anastomosis and anastomotic circumference were measured. Histopathologic examination was performed. The median distance from anal verge was 5.3(4-6) cm. No anastomotic leak or other complications were observed. All the pigs recovered and gained weight. In 5 animals sacrificed at day 14, the mean circumference of the anastomosis was 6.8(6.5-7.0) cm, and histopathological examination showed mild inflammatory reaction and fibrosis. In the one sacrificed at day 56, the circumference expanded to 9.3 cm, and no inflammation and fibrosis were observed. Minor adhesion was noticed in only one pig, while smooth and intact serosa in the anastomosis was seen in the rest of the animals. CAR27 is a promising device for mid and low colorectal anastomosis.

    The purpose of this prospective observational study was to evaluate the rate and the prognostic factors for down-staging and complete response for rectal adenocarcinoma after induction chemotherapy and neoadjuvant chemoradiation followed by surgery, and to analyze the rate of sphincter-saving surgery. We included from March 2011 to October 2013 a number of 88 patients hospitalized with locally advanced rectal adenocarcinoma in the Prof. Dr. Ion Chiricuta Institute of Oncology, Cluj. The treatment schedule included 2-4 cycles of Oxaliplatin plus a fluoropyrimidine followed by concomitant chemoradiation with a dose of 50 Gy in 25 fractions combined with a fluoropyrimidine monotherapy. The rate of T down-staging was 49.4% (40/81 evaluable patients). Independent prognostic factors for T down-staging were: age >57 years (p5 cm (p35 days (p5 cm (p=0.03). Sixty-eight patients (79.1%) underwent radical surgery and among them 35 patients (51.5 %) had a sphincter saving procedure. Induction chemotherapy with neoadjuvant chemoradiation produced important down-staging in rectal adenocarcinoma. Independent prognostic factors for T down-staging were: age, cN0, distance from anal verge, initial CEA, the number of Oxaliplatin cycles and duration of radiotherapy; for complete response: cT2, initial tumor size and distance from the anal verge.

  19. MR vs CT imaging: low rectal cancer tumour delineation for three-dimensional conformal radiotherapy.

    LENUS (Irish Health Repository)

    O'Neill, B D P

    2009-06-01

    Modern three-dimentional radiotherapy is based upon CT. For rectal cancer, this relies upon target definition on CT, which is not the optimal imaging modality. The major limitation of CT is its low inherent contrast resolution. Targets defined by MRI could facilitate smaller, more accurate, tumour volumes than CT. Our study reviewed imaging and planning data for 10 patients with locally advanced low rectal cancer (defined as < 6 cm from the anal verge on digital examination). Tumour volume and location were compared for sagittal pre-treatment MRI and planning CT. CT consistently overestimated all tumour radiological parameters. Estimates of tumour volume, tumour length and height of proximal tumour from the anal verge were larger on planning CT than on MRI (p < 0.05). Tumour volumes defined on MRI are smaller, shorter and more distal from the anal sphincter than CT-based volumes. For radiotherapy planning, this may result in smaller treatment volumes, which could lead to a reduction in dose to organs at risk and facilitate dose escalation.

    Full Text Available Laparoscopic sphincter-preserving low anterior resection for rectal cancer is a surgery demanding great skill. Immense efforts have been devoted to identifying factors that can predict operative difficulty, but the results are inconsistent.Our study was conducted to screen patients' factors to build models for predicting the operative difficulty using well controlled data.We retrospectively reviewed records of 199 consecutive patients who had rectal cancers 5-8 cm from the anal verge. All underwent laparoscopic sphincter-preserving low anterior resections with total mesorectal excision (TME and double stapling technique (DST. Data of 155 patients from one surgeon were utilized to build models to predict standardized endpoints (operative time, blood loss and postoperative morbidity. Data of 44 patients from other surgeons were used to test the predictability of the built models.Our results showed prior abdominal surgery, preoperative chemoradiotherapy, tumor distance to anal verge, interspinous distance, and BMI were predictors for the standardized operative times. Gender and tumor maximum diameter were related to the standardized blood loss. Temporary diversion and tumor diameter were predictors for postoperative morbidity. The model constructed for the operative time demonstrated excellent predictability for patients from different surgeons.With a well-controlled patient population, we have built a predictable model to estimate operative difficulty. The standardized operative time will make it possible to significantly increase sample size and build more reliable models to predict operative difficulty for clinical use.

    Full Text Available This article discusses the modern domestic research in the field of psychology of future perception and construction. Time, space, events only become meaningful when a position of observer arises, and when people are directly and vividly involved into them. The presence of human perception – an essential attribute of comprehension, appearance of the value for the time and space, in other words – the attribution of values – a separate measurement, giving the existence of time and space, allowing the existence of semantic relations, an integral component of constructing the future. An array of publications, images, ideas, «memes» on constructing the future is becoming more voluminous, but at the same time, it is very difficult to trace the evolution of a single line of ideas, concepts, theories, research directions, scientific and philosophical approaches to the practical aspects of use. The proposed concept and practical approach of contemporary researchers define a new impetus to scientific research, serves as the basis for practices and, perhaps, is the philosophy that is needed humanity, standing on sharp blades to survive in conditions of information overload, uncertainty and economic fluctuations, on the verge of which can not go – on the verge of using weapons of mass destruction, global international, cross-cultural encounters.

  3. Transmission Electron Microscopy Studies on Titanium-doped Sodium Aluminum Hydride

    Science.gov (United States)

    Culnane, Lance F.

    Hydrogen fuel cells play an important role in today's diverse and blossoming alternative energy industry. One of the greatest technological barriers for vehicular applications is the storage of hydrogen (which is required to power hydrogen fuel cells). Storing hydrogen as a gas is not volume efficient, and storing it as a liquid is not cost effective, therefore solid-state storage of hydrogen, such as in metal hydrides offers the most potential for success since many metal hydrides have attractive qualities for hydrogen storage such as: high volumetric capacity, cost efficiency, weight efficiency, low refueling times, and most importantly, high safety. Unfortunately, a compound has not been discovered which contains all of the attractive hydrogen storage qualities for vehicular applications. Sodium aluminum hydride (NaAlH 4) is one of the few compounds which is close to meeting requirements for car manufacturers, and has perhaps been researched the most extensively out of all metal hydrides in the last 15 years. This arises from the remarkable discovery by Bogdanovic who found that doping NaAlH4 with Ti dopants enabled the reversible dehydrogenation and hydrogenation of NaAlH 4 at mild conditions. Various evidence and theories have been proposed to suggest explanations for the enhanced kinetic effect that Ti-doping and ball-milling provide. However, the research community has not reached a consensus as to the exact role of Ti-dopants. If the role of titanium in the NaAlH4 dehydrogenation/hydrogenation mechanism could be understood, then more attractive metal hydrides could be designed. To this end, we conducted Transmission Electron Microscopy (TEM) studies to explain the role of the Ti dopants. The first known thorough particle size analysis of the NaAlH4 system was conducted, as well as TEM-EELS (Electron Energy Loss Spectroscopy), TEM-EDS (Energy Dispersive X-ray Spectroscopy), and in-situ imaging studies. Preparation methods were found to be important for the

    Rationale: To evaluate the response to a concomitant boost given during standard chemoradiation for locally advanced rectal cancer. Methods and Materials: Concomitant boost radiotherapy was administered preoperatively to 45 patients with locally advanced rectal cancer in a prospective trial. Treatment consisted of 45 Gy to the pelvis with 18 mV photons at 1.8 Gy/fraction using a 3-field belly board technique with continuous infusion 5FU chemotherapy (300mg/m 2 ) 5 days per week. The boost was given during the last week of therapy with a 6-hour inter-fraction interval to the tumor plus a 2-3 cm margin. The boost dose equaled 7.5 Gy/5 fractions (1.5 Gy/fraction); a total dose of 52.5 Gy/5 weeks was given to the primary tumor. Pretreatment tumor stage, determined by endorectal ultrasound and CT scan, included 29 with T3N0 [64%], 11 T3N1, 1 T3Nx, 2 T4N0, 1 T4N3, and 1 with TxN1 disease. Mean distance from the anal verge was 5 cm (range 0-13 cm). Median age was 55 years (range 33-77 years). The population consisted of 34 males and 11 females. Median time of follow-up is 8 months (range 1-24 months). Results: Sphincter preservation (SP) has been accomplished in 33 of 42 (79%) patients resected to date. Three patients did not undergo resection because of the development of metastatic disease in the interim between the completion of chemoradiation (CTX/XRT) and preoperative evaluation. The surgical procedures included proctectomy and coloanal anastomosis (n = 16), low anterior resection (n = 13), transanal resection (n = 4). Tumor down-staging was pathologically confirmed in 36 of the 42 (86%) resected patients, and 13 (31%) achieved a pathologic CR. Among the 28 tumors (67%) located <6 cm from the anal verge, SP was accomplished in 21 cases (75%). Although perioperative morbidity was higher, toxicity rates during CTX/XRT were comparable to that seen with conventional fractionation. Compared to our contemporary experience with conventional CTX/XRT (45Gy; 1.8 Gy per

    He star models in the mass range 0.4-1.0 solar mass have been evolved until the red giant phase or, depending on their mass, until crystallization on the white-dwarf cooling sequence. Some of the degenerate structures obtained in these computations have been successively accreted at various He accretion rates in order to better define the fate of the accreting dwarf versus its mass and accretion rate for a fixed degeneracy level of the accreting dwarf. He stars have been further induced to transfer mass to a degenerate companion through Roche lobe overflow, in conditions of large gravitational wave radiation by the system. CO dwarfs in binary systems with He stars are found to experience a thermal behavior whose effects are such to locate the structure on the verge of obtaining a strong SN-like explosive event. 22 refs

    Talarczyk, Małgorzata

    2012-01-01

    The point of the article is to analyse and reflect on certain symptoms of anorexia nervosa in light of Karl Jaspers and Erich Fromm's ideas and social constructivism. Contemplating the disorder in view of the philosophical ideas mentioned earlier, the author analyses such aspects of patients as: functioning on the verge of life and death, the paradoxical struggle to escape from freedom in search of independence, as well as various understandings and descriptions of anorexia in consideration of social constructivism. The author shares thoughts and poses hypotheses, trying to view anorexia in light of selected philosophical and psychological ideas, which in their general assumptions were not concerned with defining nor analysing anorexia nervosa. In view of Karl Jaspers' ideas, the author focuses on the so called 'limit-situations', in the ideas of Erich Fromm she takes notice in "Escape from Freedom" to new relations. Finally in the light of social constructivism the author focuses on the cultural context.

    On the basis of worldwide design experience and in coordination with the evolution of the International Thermonuclear Experimental Reactor (ITER) program, the application of helium as a coolant for fusion appears to be at the verge of a transition from conceptual design to engineering development. This paper presents a review of the use of helium as the coolant for fusion reactor blanket and divertor designs. The concept of a high-pressure helium cooling radial plate design was studied for both ITER and PULSAR. These designs can resolve many engineering issues, and can help with reaching the goals of low activation and high performance designs. The combination of helium cooling, advanced low-activation materials, and gas turbine technology may permit high thermal efficiency and reduced costs, resulting in the environmental advantages and competitive economics required to make fusion a 21st century power source.

    2001-01-01

    To see whether the MRI images can give a criterion for conservative therapy of the lumbar disc herniation, time changes of the images were retrospectively studied on 41 cases of spontaneous regression. They had the imaging diagnosis 3 times in average until regression with GE Signa equipment (1.5T). Images were evaluated by 2 experts. Certain cases accompanying the brightness change were seen during the process of regression. The period leading to the disappearance of melosalgia and to the regression tended to be short in cases with the brighter pulp center than disc and/or with less bright pulp verge than center. Further studies were thought necessary for clear conclusion. (K.H.)

    Immersive virtual reality (IVR) is seemingly on the verge of entering the homes of consumers. Enabling users to walk through virtual worlds in a limited physical space presents a challenge. With an outset in a taxonomy of virtual travel techniques, we argue that Walking-in-Place (WIP) techniques...... constitute a promising approach to virtual walking in relation to consumer IVR. Subsequently we review existing approaches to WIP locomotion and highlight the need for a more explicit focus on the perceived naturalness of WIP techniques; i.e., the degree to which WIP locomotion feels like real walking....... Finally, we summarize work we have performed in order to produce more natural WIP locomotion and present unexplored topics which need to be address if WIP techniques are to provide perceptually natural walking experiences....

    Full Text Available We study the high-energy behaviour of a class of anomaly-free abelian extensions of the Standard Model. We focus on the interplay among the phenomenological characterisation of the model and the use of precise renormalisation group methods. Using as boundary conditions regions of the parameter space at the verge of current LHC probe, interesting unification patterns emerge linked to thresholds belonging to a SO(10 grand unification theory (GUT. We stress how the evolution of the mixing between the two abelian factors may provide a valuable tool to address the candidate high-energy embedding. The emerging unification scenarios are then challenged to be perturbative and to allow for a stable vacuum.

  12. Piloted Simulation Evaluation of a Model-Predictive Automatic Recovery System to Prevent Vehicle Loss of Control on Approach

    2014-01-01

    This paper describes a model-predictive automatic recovery system for aircraft on the verge of a loss-of-control situation. The system determines when it must intervene to prevent an imminent accident, resulting from a poor approach. It estimates the altitude loss that would result from a go-around maneuver at the current flight condition. If the loss is projected to violate a minimum altitude threshold, the maneuver is automatically triggered. The system deactivates to allow landing once several criteria are met. Piloted flight simulator evaluation showed the system to provide effective envelope protection during extremely unsafe landing attempts. The results demonstrate how flight and propulsion control can be integrated to recover control of the vehicle automatically and prevent a potential catastrophe.

    Poliomyelitis, a dreaded disease of the last century that had already crippled millions of people across the globe, is now on the verge of eradication thanks mainly to two polio vaccines, inactivated polio vaccine (IPV) and oral polio vaccine (OPV). Ever since their development in late 1950s and early 1960s, the journey of their early development process, clinical trials, licensure and ultimately widespread clinical use in different countries provide a fascinating tale of events. Oral polio vaccine has been the mainstay of global polio eradication initiative (GPEI) in most of the countries. With the advent of 'polio endgame', the focus has now shifted back to IPV. However, there are certain issues associated with global cessation of OPV use and universal implementation of IPV in routine immunization schedules across the globe that need to be dealt with some urgency, before proclaiming the global victory over polio.

    Cosmology is in the midst of a period of revolutionary discovery, propelled by bold ideas from particle physics and by technological advances from gigapixel charge-coupled device cameras to peta-scale computing. The basic features of the universe have now been determined: It is 13.7 billion years old, spatially flat, and expanding at an accelerating rate; it is composed of atoms (4%), exotic dark matter (20%), and dark energy (76%); and there is evidence that galaxies and other structures were seeded by quantum fluctuations. Although we know much about the universe, we understand far less. Poised to dramatically advance our understanding of both the universe and the laws that govern it, cosmology is on the verge of a golden age.

    2015-07-01

    Native SAD phasing uses the anomalous scattering signal of light atoms in the crystalline, native samples of macromolecules collected from single-wavelength X-ray diffraction experiments. These atoms include sodium, magnesium, phosphorus, sulfur, chlorine, potassium and calcium. Native SAD phasing is challenging and is critically dependent on the collection of accurate data. Over the past five years, advances in diffraction hardware, crystallographic software, data-collection methods and strategies, and the use of data statistics have been witnessed which allow 'highly accurate data' to be routinely collected. Today, native SAD sits on the verge of becoming a 'first-choice' method for both de novo and molecular-replacement structure determination. This article will focus on advances that have caught the attention of the community over the past five years. It will also highlight both de novo native SAD structures and recent structures that were key to methods development.

    Psychotherapy is on the verge of a technology-inspired revolution. The concurrent maturation of communication, signal processing, and machine learning technologies begs an earnest look at how these technologies may be used to improve the quality of psychotherapy. Here, we discuss 3 research domains where technology is likely to have a significant impact: (1) mechanism and process, (2) training and feedback, and (3) technology-mediated treatment modalities. For each domain, we describe current and forthcoming examples of how new technologies may change established applications. Moreover, for each domain we present research questions that touch on theoretical, systemic, and implementation issues. Ultimately, psychotherapy is a decidedly human endeavor, and thus the application of modern technology to therapy must capitalize on-and enhance-our human capacities as counselors, students, and supervisors.

    2013-01-01

    As we stand poised on the verge of a new era of spaceflight, we must rethink every element, including the human dimension. This book explores some of the contributions of psychology to yesterday’s great space race, today’s orbiter and International Space Station missions, and tomorrow’s journeys beyond Earth’s orbit. Early missions into space were typically brief, and crews were small, often drawn from a single nation. As international cooperation in space exploration has increased over the decades, the challenges of communicating across cultural boundaries and dealing with interpersonal conflicts have become all the more important, requiring different coping skills and sensibilities than “the right stuff” expected of early astronauts. As astronauts travel to asteroids or establish a permanent colony on the Moon, with the eventual goal of reaching Mars, the duration of expeditions will increase markedly, as will the psychosocial stresses. Away from their home planet for extended times, future spac...

    Full Text Available In this paper we analyze the relationship between Hayek's theory of the state and law and the constitutionalist tradition of the eighteenth and nineteenth centuries, with a focus on Hayek's evolutionists interpretation of the origin of social institutions. I will suggest the specificity of the evolutionist approach in the context of the concept of separation of powers, and especially the functional role of the legal system, and specific emphasis on the role of the judges in the development of law. A key aspect that characterizes Hayek's approach to the theory of law is a strong emphasis on the verge of rationality and, consequently, increased the importance of customary and traditional norms in preserving the rationality of the legal system.

    Full Text Available The língu maquista is an old dialect which is part of the Portuguese heritage in Macau. This dialect, also known by patois, was commonly spoken among Macanese families until the end of the 19th century. However, from 1930 on, the lingu maquista started to fall into disuse, and nowadays it is on the verge of extinction. Quoting José dos Santos Ferreira: «in a few years now, no traces of this dialect will remain over, except for a few pale remembrances, as the nostalgic sound of a sweet melody pregnant of old memoirs». This article makes the apologia of the life and spirit of a dialect that proved to be able to absorb the Camonian prose and poetry. In addition, it testifies for the remanent marks of the Portuguese Language, linking together three continents and three geographical regions: Portugal, Macau and Brazil.

    There are widespread testimonies that the genomic instability induced by ionizing irradiation exits in mammal and its vitro cells. Genomic instability can enhance the frequency of genetic changes among the progeny of the original irradiated cells. In the radiation-leukemogenesis, there is no significant difference between controls and CBA/H mouses of PPI (preconception patent irradiation), but the offsprings of the PPI recipients show a different character (shorter latent period and higher incidence) after an extra γ-radiation. The radiation-induced genomic instability may get the genome on the verge of mutation and lead to carcinogens following mutation of some critical genes. The genomic instability, as the early event of initiation of carcinomas, may be play a specific or unique role

The paper deals with Irish that is under protection of the European Charter for regional and Minority Languages in UK and is an official language of Ireland. The research is aimed at comparing the Irish language position in both regions: Ireland and Northern Ireland. Reviewing the quantitative data in the regions under the study allows us to see clearly the language situation, monitor development, and relying on the achieved results, assess the current state and predict the future of Irish in both regions. The research results are considered to be of practical use for further language planning, improving the efficiency of language policies.

    Full Text Available For many species, the Mediterranean region harbors distinct lineages that are of conservation concerns. However, many of these are threatened by habitat degradation and by the introduction of non-native species. Here, we assess the status of the native threespine stickleback (Gasterosteus aculeatus in the Lake Bracciano region in Italy, where stickleback have been historically present. During a dedicated sampling campaign in summer 2015, surveying the potential habitats that sticklebacks commonly occupy, we could not confirm the presence of this species but found introduced species to be often most abundant. Stickleback are thus likely to either have become extinct over the last decades or be on the verge to extinction in the Lake Bracciano region.

    Canavelis, R; Grison, P

    1986-01-01

    Increasing the unit power of hydraulic turbomachines, as well as reducing their size, lead one to operate them on the verge of cavitation. It is then no more possible to think only of modifications in the machine performance, as many other phenomena take place long before this deterioration appears: noise, presence of bubbles, erosion, pressure fluctuations, etc. The article surveys the various phenomena encountered in pumps for various levels of suction pressure. Each is briefly described, with its implication on the machine. Industrial examples illustrate these phenomena and bring to light their importance. Lastly, the research tools used to study them and to overcome the present limitations are reviewed. Emphasis is made in particular on the possibility of predicting cavitation pockets either from numerical models of the flow or from experiments on actual models. Studies on erosion are also listed: mechanism, main parameters, measuring means, similitude laws for turbomachines.

    2004-01-01

    Developing scientifically sound and clinically meaningful case formulations is so challenging that it may verge on becoming a "lost art." Pressures (scientific, economic, and cultural) remain that prevent child and adolescent psychiatrists from getting a complete understanding of the patient and family. Including a strong consideration of data related to religion, spirituality, and worldview may seem only to complicate an already arduous task. The clinician who includes these factors in treatment is faced with decisions of when to discuss these issues, how to discuss them and in what depth, and finally, when to refer to a religious/spiritual professional. Nonetheless, the importance of these factors in the lives of many children and families leaves no option but to address them as directly as possible. It is well worth the effort and, in many cases, will open new areas for clinical improvement in patients.

    Gessner, T L; Morisseau, D S

    1980-11-01

    M. Brewster-Smith (1968) divided the history of psychiatry into three revolutionary periods. The first was the unshackling of the lunatics and the conception of mental illness. The second revolution was the spread of the dynamic theory of Freud with its emphasis on the one-to-one therapeutic relationship. The third revolution was the community mental health movement with its emphasis on bringing treatment into the community. We are now on the verge of yet another revolution. The new revolution is quiet and its leaders come from within the psychiatric profession. The major feature of this revolution is the binding together of medical authority and social treatment models within a corporate structure. The new movement takes the individually oriented private practitioners and shows them that in union there is profit.

    1983-09-01

    Full Text Available Translating the lyric poetry of Paul Celan, especially his later poems, carries not only the endemic challenge and difficulty of any verse translation, but the added incentive of doing justice to a writer whose whole recourse after the Holocaust—whose sanctuary, if he was to have any at all—he sought in language itself, specifically in the Muttersprache , the mother tongue that was as well the tongue of those who murdered his mother and father. This essay exposes a process of translating "Du sei wie du" (1970, which perhaps more than any other poem by Celan, at once solicits and defies translation, moving as it does from modern to medieval German, and closing with Hebrew words from Isaiah— a messianic imperative that shows Celan verging as ever on his Jewish identity.

    Using first principles calculations, we have investigated f-electron delocalization and oxidation in the actinide dioxides under pressure. Whilst UO{sub 2} is found on the verge of an insulator to metal transition at the equilibrium volume, increasingly larger pressures are required to delocalize f-electrons in NpO{sub 2}, PuO{sub 2}, and AmO{sub 2}, respectively 49, 112, and 191 GPa. Compared to this broad range of pressures, the experimentally observed structural transitions, in all four dioxides, occur between 30 and 40 GPa, which leads us to conclude that the associated volume collapse is not due to f-electron delocalization. In contrast, oxidation of the dioxides is found to be linked to the degree of f-electron localization, but it emerges that for naturally occurring pressures (<10 GPa), higher oxides only exist for UO{sub 2}.

    Full Text Available Women photographers made considerable contributions to the ‘age of emulsion’ that transformed the way art history was practiced and taught early in the twentieth century. Among American women who made great efforts to record medieval monuments were Vida Hunt Francis, who worked in France c. 1905-15, and Lucy Warren Porter whose work has previously been attributed to her husband, Arthur Kingsley Porter. Georgiana Goddard King of Bryn Mawr College preceded Porter and others in documenting medieval and renaissance sites for the Hispanic Society of America. Her co-photographer Edith H. Lowber has until now been overlooked. The last book they planned together was edited and published posthumously and most of the illustrations they prepared for it remained unpublished. King also had a great interest in modern art, through her friendship with Gertrude Stein. Occasionally the photos recall cubism, and some of her writing verges on modernist écriture feminine.

    Full Text Available One of the largest genera in the Cruciferae family in Latvia is Sisymbrium L. The genus includes not only native, but also some alien species. The distributions of the Sisymbrium species were reviewed for the first time in the last 50th years in Latvia. The distribution data were compiled from herbarium material, literature and field surveys. An identification key for the Sisymbrium species in Latvia and detailed scientific nomenclature are presented in the current study. In total, seven species of Sisymbrium were found in Latvia — S. supinum L., S. loeselii L., S. polymorphum (Murray Roth, S. volgense M. Bieb. ex E. Fourn., S. altissimum L., S. orientale L. and S. officinale (L. Scop. The mainly were recorded in railway verges, roadsides, waste dumps and wasteland. Five species of the genus are alien to the flora of Latvia — S. loeselii, S. altissimum, S. polymorphum, S. orientale, and S. volgense; two are native — S. supinum and S. officinale.

  18. Watershed development practices for ecorestoration in a tribal area - A case study in Attappady hills, South India

    Science.gov (United States)

    Vishnudas, Subha; Savenije, Hubert H. G.; Zaag, Pieter Van der

    Attappady is a rural area in Kerala, South India, that has suffered from severe land degradation and which is inhabited by a poor and predominantly tribal population. The combination of severe land degradation, poverty and a tribal population make Attappady hydrologically and socially unique. Ecological degradation and deforestation followed the gradual building up of land pressure resulting from immigration by more wealthy outsiders. The hills of Attappady were once the forest land of Kerala. Recently it was on the verge of complete degradation. This paper explains how an ecorestoration project involving soil and water conservation interventions, the introduction of agro-forestry, nutritional diversification, income generation activities and training was implemented in a participatory manner. The project had positive impacts on both the environment and the livelihoods of the people living in the watershed, but it also suffered from drawbacks. This paper reports on the successes as well as the lessons learned from this unique ecorestoration project.

    Full Text Available Contemporary anxieties around cloning and genetic modification have deep roots in a nineteenth- and twentieth-century tradition of narrative thought-experiments about the artificial reproduction of human life. In the ‘strange wickedness’ to which HG Wells’s narrator refers—as good a condensation of the tradition’s topic as any—strangeness has always been as prominent as wickedness. In that tradition the myths of Prometheus and Faust, of the golem and the doppelgänger, together with fables and fictions concerning automata and scientifically produced monsters and/or reflections on the real and the illusory, have con- verged to define a problematics of the sorcerer’s apprentice. We will see that such a problematics reflects a powerful fear of artifice, or more accurately a phobia: a fear of artifice as great as the attraction it also exerts.

  1. Searches for new particles at LEP

    1991-12-01

    A review of the results from ALEPH, DELPHI, L3, and OPAL on searches for new particles is given. No evidence for a positive signal is seen, but significant and constraining limits are placed. In particular, the Standard Higgs boson must be heavier than 57 GeV and Higgs bosons from the minimal supersymmetric theories are strongly constrained, with the lightest CP-even state heavier than 43 GeV and the CP-odd state heavier than 20 GeV. Precision electroweak measurements of the Z parameters are on the verge of producing Higgs-sensitive results. No indication of compositeness is found for fermions and for the Z 0 boson, and the transition Z → 3γ has to be smaller than 10 -5 of the total Z rate. Lepton flavour conservation still holds in Z decays at a level of a few 10 -5 . (author) 67 refs., 41 figs., 9 tabs

    We consider (1+1)-dimensional dilaton gravity with a reflecting dynamical boundary. The boundary cuts off the region of strong coupling and makes our model causally similar to the spherically-symmetric sector of multidimensional gravity. We demonstrate that this model is exactly solvable at the classical level and possesses an on-shell SL(2, ℝ) symmetry. After introducing general classical solution of the model, we study a large subset of soliton solutions. The latter describe reflection of matter waves off the boundary at low energies and formation of black holes at energies above critical. They can be related to the eigenstates of the auxiliary integrable system, the Gaudin spin chain. We argue that despite being exactly solvable, the model in the critical regime, i.e. at the verge of black hole formation, displays dynamical instabilities specific to chaotic systems. We believe that this model will be useful for studying black holes and gravitational scattering.

  3. Meaning production about an absent image: towards Lula’s coercive conduction in the scope of Operation Lava-Jato

    Directory of Open Access Journals (Sweden)

    Janaina Cardoso Brum

    2017-11-01

    Full Text Available In March 2016, the former president Lula was conducted through a coercive way by the Federal Police in order to depose about his involvement in suspect activities related to Operation Lava Jato. The shooting or any other register of this coercive conduction have been forbidden, thus the national media began to work in the verge of this “denied image”. In this paper, we investigate the process of meaning production about this “absent image” through other images and materialities that circulate in the media discourse game regarding the destabilization/ stabilization of evidence about the March fourth current events. Therefore, the concept of lack, excess and strangeness, established by Ernst, were fundamental. We started with the hypothesis that, answering the lack of imagetic register, it was established a profusion of other imagetic, audiovisual and/or verbal discourses.

    2017-08-01

    We elucidate the origin of the phonon-mediated superconductivity in 2 H -NbS2 using the ab initio anisotropic Migdal-Eliashberg theory including Coulomb interactions. We demonstrate that superconductivity is associated with Fermi surface hot spots exhibiting an unusually strong electron-phonon interaction. The electron-lattice coupling is dominated by low-energy anharmonic phonons, which place the system on the verge of a charge density wave instability. We also provide definitive evidence for two-gap superconductivity in 2 H -NbS2 , and show that the low- and high-energy peaks observed in tunneling spectra correspond to the Γ - and K -centered Fermi surface pockets, respectively. The present findings call for further efforts to determine whether our proposed mechanism underpins superconductivity in the whole family of metallic transition metal dichalcogenides.

    2002-01-01

    Seismic profiles and well data from the Doukkala basin unravel the structure of the Palaeozoic basement and suggest that this coastal zone of western Morocco was affected by a compressive phase during the Frasnian. This resulted in the formation of upright, plurikilometric folds associated with reverse faults (North Doukkala), and of asymmetrical folds associated with mostly west verging ramps (South Doukkala). Folding involved all pre-Upper Frasnian formations and caused partial or total hiatus of Upper Frasnian-Strunian strata. This event can be correlated with the orogenic phase reported from more internal domains of the Morocco Hercynian belt, where it is referred to as the 'Bretonne' or 'Eovariscan' phase.

  6. A hydrogen economy and its impact on the world as we know it

    International Nuclear Information System (INIS)

    2008-01-01

    An assortment of governmental, technological, environmental, and economic factors has combined to spur renewed interest in alternatives to petroleum, and especially in hydrogen. While there is no clear consensus on the viability of the technology, governments and corporations alike have vigorous hydrogen research programs. The result is that hydrogen may stand on the verge of becoming a true successor to oil. A transition from oil to hydrogen would alter familiar global economic and political structures in profound ways. The ramifications will influence developed and developing nations, oil importers, and exporters alike. New alliances among governments, corporations, and other groups may challenge existing notions of governance. Although a hydrogen-based economy may be decades away, the vision for it requires near- and mid-term thinking to manage the transition smoothly. Further, hydrogen is only a metaphor; any change from the current oil economy will entail dramatic changes to the global status quo that must be planned for now

    In the context of an ongoing change, management is required to take the form of a leadership that must be reignited over and over again. The article examines a new art of leadership that may be viewed as an attempt to keep up with these challenges and stay ahead of time. It emerges from...... a pilgrimage leadership learning laboratory on the road to Santiago de la Compostela. This moving lab creates situations of extraordinary intensity that border on hyperreality and force the leader to find him/herself anew on the verge of him/herself. Conceived as pilgrimage, leadership moves ahead of time...... as it reaches into and anticipates a future still unknown. In this setting, anticipatory affects and the virtual take up a predominant role. As it emerges here, leadership distinguishes itself not only from leadership in the traditional sense, but also from management and governmentality....

    2008-01-01

    After x-ray 5 Gy radiation on the whole body of a mouse using a linear accelerator, its leucocyte, erythrocyte, and platelet were observed by SEM. Also, after injecting propolis into the abdominal cavity, the radio-protective effect of blood corpuscles was studied. The observation of micromorphology in blood corpuscles revealed that the number of leukocyte, erythrocyte, and thrombocyte decreased in the experimental group and the lump got together in blood corpuscles after 10 and 20 days. In RBC, crack or break on the surface and poikilosperocytes were observed. In the irradiation group, the size of leucocytes was smaller than that in control group and the number of villus at the verge substantially decreased. The blood corpuscles in the propolis group, however, had the similar results to control group.

    Clergy members suffering from burnout face both personal and professional complications. This study assessed occupational burnout and stress coping mechanisms among ministers affiliated with the Assemblies of God, a denomination that has received little attention in previous burnout-related studies. A cross-sectional design was employed using two instruments with acceptable psychometric properties. Approximately 65 % of those surveyed were either suffering from burnout or on the verge of burnout. Statistical differences in coping mechanism use were found between those who were and were not experiencing some level of burnout. The results of this study add to the existing understanding of occupational burnout among clergy members and ways in which burnout may be alleviated.

    Full Text Available It has been constantly viewed that the developed economies unevenly ruled the governance structures in the international organizations such as International Monetary Fund (MF. The continuous development in Emerging and Developing Economies (EDEs over the last 20 years witnessed their growing importance in the world economy, but at the same time little increase in their voice in the IMF. There are reasons for the discontent of the EDEs in the present structure such as the increase of regional monetary arrangements, uneven distribution of quota shares, IMF quota reforms, and IMF voting structure. The world economy is witnessing a tremendous growth of these EDEs and is now at the verge where Asian economies are capable of leading, rather than the North Atlantic economies. This issue should be acknowledged properly and must be responded adequately. This paper makes an attempt to understand the prime issues that should be fixed in the current quotas system and voting structure in the IMF.

    Full Text Available Gastric mucosal heterotopia has been described in all levels of the gastrointestinal tract. Its occurrence in the rectum is uncommon. We report the case of a 4-year-old boy referred to Pediatric Gastroenterology for intermittent rectal bleeding for the past 2 years. Total ileocolonoscopy revealed a flat, well-circumscribed lesion of 4 cm, with elevated margins, localized at 10 cm from the anal verge. Histologic examination showed typical gastric mucosa of the oxyntic type. Treatment with proton pump inhibitors was started without resolution of the symptoms and, therefore, an endoscopic mucosal resection was performed. Heterotopic gastric mucosa represents a rare cause of rectal bleeding in children and endoscopic evaluation is fundamental for diagnosis. Although not usually performed in pediatric ages, endoscopic mucosectomy allows complete resolution of the problem avoiding surgery.

    2011-01-01

    Within a few years, the first commercial operators will start flying passengers on suborbital flights to the verge of space. Medical data on the effects of space journeys on humans have mainly been provided by professional astronauts. There is very little research into the aeromedical consequences of suborbital flights for the health of untrained passengers. Low air pressure and oxygen tension can be compensated for by pressurising the spacecraft or pressure suit. Rapid changes in gravitational (G-)force pose ultimate challenges to cardiovascular adaptation mechanisms. Zero-gravity and G-force may cause motion sickness. Vibrations and noise during the flight may disturb communication between passengers and crew. In addition, the psychological impact of a suborbital flight should not be underestimated. There are currently no legal requirements available for medical examinations for commercial suborbital flights, but it seems justifiable to establish conditions for potential passengers' states of health.

    2013-06-01

    Full Text Available The present study paper shows an alternative source of energy that can decrease the extensive use of fire wood in Ethiopia. The country’s entire rural area and significant part of urban population is completely dependent on fire wood as a source of energy. This practice takes its own toll, the forest is on the verge of being wiped out and as a result a clear change of climate and loss of natural biodiversity resources is visible. Fire wood is not the only source of energy available in the country. In this paper, based on their low cost, construction material availability and the required unskilled labor it is shown that biogas and solar energy are potentially feasible source of energy to replace firewood for cooking.

    2014-06-01

    This article examines the intertextual presence of Nicholas Ray’s Johnny Guitar from the deconstructive lenses of Almodovar’s Women on the Verge of a Nervous Breakdown. Almodovar’s embrace of postmodernist esthetics embodies an intricate questioning of the veracity of love as it has been portrayed by culturally legitimizing sources like the Hollywood film industry. The love dissolution his film portrays does not result in spiritual or metaphysical crisis but rather in the revelation of the truth of love as another performance. This critique of love’s essentialist identity intersects with other deconstructive approaches to gender identities and traditional concepts of happiness. Women posits femininity as a as masquerade, lays bare cultural inflections of the seducer and suggests alternative models of what can be conceived as happiness.

    2007-01-01

    There is a widespread belief that significant cross subsidies exist in the water, gas and electricity utility industries, particularly those under public ownership. In this paper we discuss the measurement of cross subsidy and its regulatory implications in the context of a publicly owned utility on the verge of being opened up to product market competition. Using the case of the publicly owned Scottish water industry the paper outlines the definition and measurement of cross subsidy in theoretical terms before reviewing the policy debate over the desirability of cross subsidy between different customer groups and services. It then explains the approach to measurement recently adopted by the Scottish Executive. Having established the size and direction of cross subsidy the regulatory implications are considered.

    More than ever before, management and technical professionals are concerned with the subtle and dynamic relationships between safety and performance in complex and hazardous industries. This is certainly true in the nuclear power industry. With the US electric energy industry on the verge of deregulation and increased competition, and with a virtual stoppage on building new nuclear power plants, the increasing demand for reliable sources of efficient electric energy is pressing the nuclear utilities to increase production. At the same time, public sentiment and regulatory pressures are increasing their focus on safety at all costs. The purpose of this paper is to present a proven approach to creating a new work culture for improved nuclear safety and performance. The concepts and material which make up this paper have been taken from both authors experience, research, and consulting in the nuclear industry for several years, as well as from over 20 years of consulting work on the relationships between organizational behavior, culture, and productivity

    Full Text Available Seismic attribute analysis approach has been applied for the interpretation and identification of fault geometry of Zamzama Gas Field. Zamzama gas field area, which lies in the vicinity of Kirthar fold and thrust belt, Southern Indus Basin of Pakistan. The Zamzama fault and its related structure have been predicted by applying the Average Energy Attribute, Instantaneous Frequency Attribute, relative Acoustic Impedance Attribute and Chaotic Reflection Attribute on the seismic line GHPK98A.34. The results have been confirmed by applying the spectral decomposition attribute on the same seismic line that reveal the geometric configuration of Zamzama structure. The fault is reverse and started from 0 s and ended at the depth of 2.5 s on the vertical seismic section. Hanging wall moves up along the fault plane under the action of eastward oriented stress, which formed a large north–south oriented and eastward verging thrusted anticline.

    2016-01-01

    The treatment of cancer patients with autologous T cells expressing a chimeric antigen receptor (CAR) is one of the most promising adoptive cellular therapy approaches. Reproducible manufacturing of high-quality, clinical-grade CAR-T cell products is a prerequisite for the wide application of this technology. Product quality needs to be built-in within every step of the manufacturing process. We summarize herein the requirements and logistics to be considered, as well as the state of the art manufacturing platforms available. CAR-T cell therapy may be on the verge of becoming standard of care for a few clinical indications. Yet, many challenges pertaining to manufacturing standardization and product characterization remain to be overcome in order to achieve broad usage and eventual commercialization of this therapeutic modality.

    2015-01-01

    The author's thoughts and opinions on where the field of forensic DNA testing is headed for the next decade are provided in the context of where the field has come over the past 30 years. Similar to the Olympic motto of ‘faster, higher, stronger’, forensic DNA protocols can be expected to become more rapid and sensitive and provide stronger investigative potential. New short tandem repeat (STR) loci have expanded the core set of genetic markers used for human identification in Europe and the USA. Rapid DNA testing is on the verge of enabling new applications. Next-generation sequencing has the potential to provide greater depth of coverage for information on STR alleles. Familial DNA searching has expanded capabilities of DNA databases in parts of the world where it is allowed. Challenges and opportunities that will impact the future of forensic DNA are explored including the need for education and training to improve interpretation of complex DNA profiles. PMID:26101278

    Advances in technology regarding underground transformers was discussed. After more than 3 years of research, CITEQ (Centre d'innovation sur le transport d'energie du Quebec), a new company founded by Hydro-Quebec and ABB, is on the verge of a breakthrough with a new submersible transformer with solid insulation. This transformer was specially designed for use in underground electric networks. The new transformer is a good alternative to conventional oil transformers which have a high risk of pollution mainly due to corrosion, leaks, explosions or fires. Also, the outer shell of the new transformer is composed of composite material which will eliminate the need for maintenance. The service life of the new transformer is expected to be approximately 30 to 40 years. CITEQ is hoping that this new technology will benefit the residential sector which is powered by underground distribution networks. 1 fig

    We show that the gravitino-overproduction problem is prevalent among inflation models in supergravity. An inflaton field {phi} generically acquires (effective) non-vanishing auxiliary field G{sup (eff)}{sub {phi}}, if the Kaehler potential is non-minimal. The inflaton field then decays into a pair of the gravitinos. We extensively study the cosmological constraints on G{sup (eff)}{sub {phi}} for a wide range of the gravitino mass. For many inflation models we explicitly estimate G{sup (eff)}{sub {phi}}, and show that the gravitino-overproduction problem severely constrains the inflation models, unless such an interaction as K={kappa}/2 vertical stroke {phi} vertical stroke {sup 2}z{sup 2}+h.c. is suppressed (here z is the field responsible for the supersymmetry breaking). We find that many of them are already excluded or on the verge of, if {kappa}{proportional_to}O(1). (Orig.)

    Full Text Available The treatment of cancer patients with autologous T cells expressing a chimeric antigen receptor (CAR is one of the most promising adoptive cellular therapy approaches. Reproducible manufacturing of high-quality, clinical-grade CAR-T cell products is a prerequisite for the wide application of this technology. Product quality needs to be built-in within every step of the manufacturing process. We summarize herein the requirements and logistics to be considered, as well as the state of the art manufacturing platforms available. CAR-T cell therapy may be on the verge of becoming standard of care for a few clinical indications. Yet, many challenges pertaining to manufacturing standardization and product characterization remain to be overcome in order to achieve broad usage and eventual commercialization of this therapeutic modality.

  12. Why Corporatism Collapsed in South Africa: The Significance of NEDLAC

    Directory of Open Access Journals (Sweden)

    Yejoo Kim

    2015-01-01

    Full Text Available The National Economic Development and Labour Council (NEDLAC was established as a corporatist institution, defined as a representative and consensus-seeking body coordinating to reach agreement through negotiation and discussion involving the state, organised business, and organised labour. It signalled the equal participation of the state and societal actors in the decision-making process in democratic South Africa. However, after two decades, NEDLAC is facing questions regarding its relevance. The imbalance in the power dynamics diminished the power of labour to bargain vis-à-vis the state and business. Labour’s inability to represent a broader constituency beyond the formally employed, the lack of technical capacity within the labour movement, and NEDLAC’s organisational inefficiency negatively affected the corporatist institution, which is now on the verge of demise.

  13. The grotesque female in Malaysian poems: shaping the migrant's psyche.

    Science.gov (United States)

    DMani, Sheba

    2011-12-01

    The works of Malaysian poet, Wong Phui Nam's Against the Wilderness (vii) China bride and Variations on a Birthday Theme (iv) Kali, illustrate a bride and a mother in terrifying images. Wong's stylistic form of representing the female body through startling images of inversion and degradation evoke feelings of unease. The suspension between the known and the unknown causes a bewildering reality verging on madness. Interpreted through the lens of the carnivalesque, specifically, the grotesque body, festive language and parody, I attempt to reconstruct the psyche of the Chinese migrant which underpins these poems. The migrant who arrived in Malaya during the colonial era in the early nineteenth century faced political and social struggles in adapting to a new land. In the poems, the migrant juxtaposes his position to a female and uses the female body as a site of contention to intensify the torment of the psyche and to reflect the despair of the Chinese in Malaysia.

    1978-01-01

    Spoil tips associated with abandoned non-ferrous mines contain anomalously high levels of heavy metals compared with other contaminated environments. Little attention has been given to the impact of such contaminated environments on terrestrial ecosystems. In this study, lead in soil, vegetation, ground-living invertebrates and indigenous small mammal populations are reported for two derelict mines in Wales. Small mammal body and tissue lead concentrations were markedly elevated compared with control populations and with published data for other lead-contaminated areas. Oedema, intranuclear inclusion bodies and mitochondrial abnormalities--symptoms of clinical plumbism--were identified in kidney tissue in populations with highest tissue lead concentrations. The results and their relevance to other lead-contaminated areas, including roadside verges, are discussed.

    Semenov, D. A.

    2012-01-01

    In this lecture I discuss recent progress in the understanding of the chemical evolution of protoplanetary disks that resemble our Solar system during the first ten million years. At the verge of planet formation, strong variations of temperature, density, and radiation intensities in these disks lead to a layered chemical structure. In hot, dilute and heavily irradiated atmosphere only simple radicals, atoms, and atomic ions can survive, formed and destroyed by gas-phase processes. Beneath the atmosphere a partly UV-shielded, warm molecular layer is located, where high-energy radiation drives rich chemistry, both in the gas phase and on dust surfaces. In a cold, dense, dark disk midplane many molecules are frozen out, forming thick icy mantles where surface chemistry is active and where complex (organic) species are synthesized.

Whole soil samples were subjected to salinities corresponding to marine conditions and clonal cultures were used to perform growth and adaptation experiments at a wide range...... of different salinities (0-50 ppm). More morphotypes tolerant to elevated NaCl levels were found in road verge soil that was heavily exposed to de-icing salt than in less exposed soils, though there were fewer tolerant than intolerant morphotypes in all soils examined. Heterotrophic flagellates isolated...... on a freshwater medium from a non-exposed soil were unable to thrive at salinities above 15 ppt, and showed reduced growth rates even at low salt salinities (1-5 ppt). The findings suggest that heterotrophic soil flagellates are less tolerant to NaCl than their aquatic relatives, possibly due to their long...

    1996-06-01

    Geometry of the triangle zone and its variations in the region lying between the Berland River and the Smoky River in the central Alberta Foothills was described by drawing closely spaced balanced structural cross-sections, constrained by seismic data interpretation and well-log analysis. The stratigraphic sequence (Devonian to Tertiary in the northwest, or Mississipian to Tertiary in the southeast) was found to have been divided into three structural packages by three detachments. In the northwest, the lower detachment lies in the Lower Devonian Woodbend Group, the middle detachment in the Shaftesbury Formation, and the upper detachment in the upper Kaskapau Formation. Each of these detachment combined with the foreland-verging thrust sheet beneath them to form the triangle zone structure. Based on the peculiarities of the geology, it is suspected that the higher triangle zone was formed before the lower triangle zone. 31 refs., 10 figs.

  1. How noise and coupling influence leading indicators of population extinction in a spatially extended ecological system.

    Science.gov (United States)

    O'Regan, Suzanne M

    2018-12-01

    Anticipating critical transitions in spatially extended systems is a key topic of interest to ecologists. Gradually declining metapopulations are an important example of a spatially extended biological system that may exhibit a critical transition. Theory for spatially extended systems approaching extinction that accounts for environmental stochasticity and coupling is currently lacking. Here, we develop spatially implicit two-patch models with additive and multiplicative forms of environmental stochasticity that are slowly forced through population collapse, through changing environmental conditions. We derive patch-specific expressions for candidate indicators of extinction and test their performance via a simulation study. Coupling and spatial heterogeneities decrease the magnitude of the proposed indicators in coupled populations relative to isolated populations, and the noise regime and the degree of coupling together determine trends in summary statistics. This theory may be readily applied to other spatially extended ecological systems, such as coupled infectious disease systems on the verge of elimination.

  2. What will happen to retirement income for 401(k) participants after the market decline?

    VanDerhei, Jack

    2010-04-01

    This paper uses administrative data from millions of 401(k) participants dating back to 1996 as well as several simulation models to determine 401(k) plans' susceptibility to several alleged limitations as well as its potential for significant retirement wealth accumulation for employees working for employers who have chosen to sponsor these plans. What will happen to 401(k) participants after the 2008 market decline will be largely determined by the extent to which the features of automatic enrollment, automatic escalation of contributions, and automatic investment are allowed to play out. Simulation results suggest that the first two features will significantly improve retirement wealth for the lowest-income quartiles going forward, and the third feature (primarily target-date funds) suggest that a large percentage of those on the verge of retirement would benefit significantly by a reduction of equity concentrations to a more age-appropriate level.

It is suggested that an incubation period for the production of new mobile dislocations arises because attractive junctions on the verge of breaking just before the stress reduction are no longer so after...... the stress reduction. The breaking stress of the junctions must be lowered by climb movements in the surrounding network before the junctions can break and release new mobile dislocations.

    Approximately 100 species become extinct a day. Despite increasing interest in using cloning to rescue endangered species, successful interspecies nuclear transfer has not been previously described, and only a few reports of in vitro embryo formation exist. Here we show that interspecies nuclear transfer can be used to clone an endangered species with normal karyotypic and phenotypic development through implantation and the late stages of fetal growth. Somatic cells from a gaur bull (Bos gaurus), a large wild ox on the verge of extinction, (Species Survival Plan cloned animals was gaurus in origin. The gaur nuclei were shown to direct normal fetal development, with differentiation into complex tissue and organs, even though the mitochondrial DNA (mtDNA) within all the tissue types evaluated was derived exclusively from the recipient bovine oocytes. These results suggest that somatic cell cloning methods could be used to restore endangered, or even extinct, species and populations.

    2018-02-27

    This is an exciting time for hydrogen fuel-cell electric vehicles (FCEVs). They seem to be on the verge of a major market breakthrough. However, those of us who have been working in the hydrogen and FC industry for a while are familiar with the boom and bust cycle of FCEV hype-it feels like we have been here before. The first FC automobile was designed as far back as the 1960s. NASA was using FCs to power its spacecraft, and, in 1966, General Motors (GM) used this space-age technology in the prototype GM Electrovan. The Electrovan used the body and chassis of GM's Handivan, their production utility van at the time. The FC and hydrogen components for this vehicle filled nearly the entire available space of the van. At this point, FCs were clearly too expensive and impractical for production vehicles.

    The taxonomy of farmers markets requires an update to encompass the expanding range of available options. Also absent from the literature is an appreciation of the connection between market types, ideological stances, social characteristics, and conflict-necessary for understanding the social processes, motivations, and expectations that create a farmers market. Our study of a long-standing farmers market on the verge of municipal revamping aims to unite these interests, with a focus on the diverse demographics and values of the social groups involved. We propose a synthetic two-dimensional scheme to classify U.S. farmers markets. Bourdieu's theory of distinction is instrumental in making sense of the diversity encountered.

    This presentation describes a model-predictive automatic recovery system for aircraft on the verge of a loss-of-control situation. The system determines when it must intervene to prevent an imminent accident, resulting from a poor approach. It estimates the altitude loss that would result from a go-around maneuver at the current flight condition. If the loss is projected to violate a minimum altitude threshold, the maneuver is automatically triggered. The system deactivates to allow landing once several criteria are met. Piloted flight simulator evaluation showed the system to provide effective envelope protection during extremely unsafe landing attempts. The results demonstrate how flight and propulsion control can be integrated to recover control of the vehicle automatically and prevent a potential catastrophe.

    Damped oscillations of the current were observed in the transient current pulse characteristics of a 30-period weakly coupled GaAs/AlGaAs superlattice (SL). The switching time of the current is exponentially decreased as the voltage is verged towards the current discontinuity region indicating that the space charge necessary for the domain boundary formation is gradually accumulated in a certain SL period in a timescale of several hundreds ns. The spectral features in the electroluminescence spectra of two connected in parallel SL mesas correspond to the energy of the intersubband transitions and the resonance detuning of subbands caused by charge trapping in the quantum wells (QWs) residing in a region of the expanded domain boundary. The obtained results support our understanding of the origin of self-oscillations as a cyclic dynamics of the subband structure in the QWs forming the expanded domain boundary.

    The White-tailed Kite (Elanus leucurus) was once a common raptor species in the southern United States. However, by the 1930s, the species was considered on the verge of extinction until the 1940s, when a trend towards recovery was apparent. These dramatic fluctuations may be related to changes in rodent prey base due to the conversion of native wetlands to agriculture. To investigate the effects of changes in habitat, land use practices, and prey base on kite populations, we collected tissue samples from kites, their prey, and vegetation at four different locations in California: Arcata, Coastal-Coniferous Forest; Davis, mixed Urban-Agricultural; Cosumnes, Mixed Wetland-Agriculture, and Santa Barbara, Coastal-Chaparral.

  13. Disseminação linfática na endometriose colorretal

    Full Text Available A 40-year-old female patient presented abdominal pain during her periods and progressing constipation during the last 6 years. Retosigmoidoscopy showed a stenotic lesion 14cm above the anal verge. The patient underwent a retosigmoidectomy and the specimen was sent to histopathologic exam. The diagnose was endometriosis with the involvement of the colon and rectum, associated with dissemination of the endometrial cells by the lymph nodes. The patient recovered well and was discharged on the 6th postoperative day. It is commented on the rarity of the lymphatic dissemination in these cases and according to the reviewed literature, this is the 5th case reported. Thus, dissemination of the disease to extra-abdominal sites could possibly occur by this route. Therefore, pathologists should carefully exam the lymph nodes of the mesocolon in these specimens because findings of endometrial "metastasis" may be present.

    Manufacturers in Japan and Europe are developing the hardware necessary for commercially feasible direct broadcast satellite TV, including high-frequency circuits and mini-dishes for spacecasting. US companies are lagging behind due to formidable regulatory and legal difficulties. The article focuses on efforts to develop simple, inexpensive receivers which will be able to convert 12-GHz satellite transmissions into high-quality TV images. Three basic receiver designs are being developed: the mixer-downcaster, microwave integrated circuits using FET-preamplifier front ends with transistors connected by bond-wires, and monolithic gallium arsenide integrated circuits. Several companies are on the verge of introducing commercialized receivers utilizing these different basic designs.

    When the 20th century began, Baku was a boom town without equal in the Russian empire. The city developed into a legendary cultural center, where some of the West's leading commercial geniuses made substantial investments. Baku also was a city of diverse peoples, with its Azerbaijani core supplemented by substantial communities of Armenians, Germans, Russians and Swedes, not to mention merchant communities of other central Asian and Middle Eastern peoples. The miracle that caused Baku to bloom, then as now, was the promise of oil. Baku is arguably the world's first important oil-producing city. As the 20th century draws to a close, Baku once more is on the verge of a transition that may restore its status as an important center for international investment and commerce. This article examines Azerbaijan's legal environment as it relates to the natural resources sector

    This report describes Earth's radiation budget IKOR-M satellite program which has been started in Russia. The first satellite "Meteor-M» No 1 of this project was put into orbit in September, 2009. The IKOR-M radiometer is a satellite instrument that measures reflected shortwave radiation (0.3-4.0 µm). It was created in Saratov State University and installed on Russian hydrometeorological satellites "Meteor-M" No 1 and No 2. Radiometer IKOR-M designed for satellite monitoring of the outgoing reflected short-wave radiation, which is one of the components of Earth's radiation budget. Such measurements can be used to derive Earth's surface albedo and absorbed solar radiation. This information also can be used in different models of long-term weather forecasts and in researches of climate change trends (Sklyarov et al., 2016). Satellite "Meteor-M" No 1 and No 2 are heliosynchronous that allows observing from North to South Poles. The basic products of data processing are given in the form of global maps of distribution outgoing short-wave radiation (OSR), albedo and absorbed solar radiation (ASR). Such maps were made for each month during observation period. The IKOR-M product archive is available online at all times. A searchable catalogue of data products is continually updated and users may search and download data products via the Earth radiation balance components research laboratory website (http://www.sgu.ru/structure/geographic/metclim/balans) as soon as they become available. Two series of measurements from two different IKOR-M are available. The first radiometer had worked from October, 2009 to August, 2014 and second - from August, 2014 to the present. Therefore, there is a period when both radiometers work at the same time. Top-of-atmosphere fluxes deduced from the "Meteor-M" No 1 measurements in August, 2014 show very good agreement with the fluxes determined from "Meteor-M" No 2 (Bogdanov et al., 2016). The effect of aging is investigated for first IKOR

    The Salalah Crystalline Basement (SCB) is the largest Precambrian exposure in Oman located on the southern margin of the Arabian Plate at the Arabian Sea shore. This work used remote sensing, detailed structural analysis and the analysis of ten samples using 40Ar/39Ar age dating to establish the Precambrian evolution of the SCB by focusing on its central and southwestern parts. This work found that the SCB evolved through four deformational events that shaped its final architecture: (1) Folding and thrusting event that resulted in the emplacement of the Sadh complex atop the Juffa complex. This event resulted in the formation of possibly N-verging nappe structure; (2) Regional folding event around SE- and SW-plunging axes that deformed the regional fabric developed during the N-verging nappe structure and produced map-scale SE- and SW-plunging antiforms shaping the complexes into a semi-dome structure; (3) Strike-slip shearing event that produced a conjugate set of NE-trending sinistral and NW-trending dextral strike-slip shear zones; and (4) Localized SE-directed gravitational collapse manifested by top-to-the-southeast kinematic indicators. Deformation within the SCB might have ceased by 752.2+/-2.7 Ma as indicated by an age given by an undeformed granite. The thermochron of samples collected throughout the SCB complexes shows a single cooling event that occurred between about 800 and 760 Ma. This cooling event could be accomplished by crustal exhumation resulting in regional collapse following the prolonged period of the contractional deformation of the SCB. This makes the SCB a possible metamorphic core complex.

    Purpose: We retrospectively evaluated the effects of clinical and pathologic factors on disease-free survival (DFS) with the aim of identifying the most discriminating factor predicting DFS in rectal cancer patients treated with preoperative chemoradiotherapy (CRT) and curative resection. Methods and Materials: The study involved 420 patients who underwent preoperative CRT and curative resection between August 2001 and October 2006. Gender, age, distance from the anal verge, histologic type, histologic grade, pretreatment carcinoembryonic antigen (CEA) level, cT, cN, cStage, circumferential resection margin, type of surgery, preoperative chemotherapy, adjuvant chemotherapy, ypT, ypN, ypStage, and tumor regression grade (TRG) were analyzed to identify prognostic factors associated with DFS. To compare the discriminatory prognostic ability of four tumor response-related pathologic factors (ypT, ypN, ypStage, and TRG), the Akaike information criteria were calculated. Results: The 5-year DFS rate was 75.4%. On univariate analysis, distance from the anal verge, histologic type, histologic grade, pretreatment CEA level, cT, circumferential resection margin, type of surgery, preoperative chemotherapeutic regimen, ypT, ypN, ypStage, and TRG were significantly associated with DFS. Multivariate analysis showed that the four parameters ypT, ypN, ypStage, and TRG were, consistently, significant prognostic factors for DFS. The ypN showed the lowest Akaike information criteria value for DFS, followed by ypStage, ypT, and TRG, in that order. Conclusion: In our study, ypT, ypN, ypStage, and TRG were important prognostic factors for DFS, and ypN was the most discriminating factor.

    We processed crustal seismic profile SIRIPRO, acquired across Central Sicily. To improve the seismic image we utilized the wave equation datuming technique, a process of upward or downward continuation of the wave-field between two arbitrarily shaped surfaces. Wave equation datuming was applied to move shots and receivers to a given datum plane, removing time shifts related to topography and to near-surface velocity variations. The datuming procedure largely contributed to attenuate ground roll, enhance higher frequencies, increase resolution and improve the signal/noise ratio. Processed data allow recognizing geometries of crust structures differentiating seismic facies and offering a direct image of ongoing tectonic setting within variable lithologies characterizing the crust of Central Sicily. Migrated sections underline distinctive features of Hyblean Plateau foreland and above all a crustal thinning towards the Caltanissetta trough, to the contact with a likely deep Permo-Triassic rifted basin or rather a zone of a continent to oceanic transition. Inhomogeneity and fragmentation of Sicily crust, with a distinct separation of Central Sicily basin from western and eastern blocks, appear to have guided the tectonic transport inside the Caltanissetta crustal scale syncline and the accumulation of allochthonous terrains with south and north-verging thrusts. Major tectonic stack operated on the construction of a wide anticline of the Maghrebian chain in northern Sicily. Sequential south-verging imbrications of deep elements forming the anticline core denote a crust wedge indenting foreland structures. Deformation processes involved multiple detachment planes down to decoupling levels located near crust/mantle transition, supporting a presence of high-density lenses beneath the chain, interrelated to a southwards push of Tyrrhenian mantle and asthenosphere.

    This report is based on a series of 108 patients with clinically staged T2 (9), T3 (94) and T4 (5) rectal cancer treated with preoperative irradiation with 25 Gy, 5 Gy per fraction given for one week. In 77% of patients, the tumour was located within 7 cm of the anal verge and in 15% the anal canal was involved. Surgery was usually undertaken during the week after irradiation. For low tumours, total mesorectal excision was performed, and for middle and upper cancers, the whole circumference of the mesorectum was excised at least 2 cm below the lower pole of a tumour. Tumour was resected in 103 patients, and sphincter-preserving surgery was performed in 73% of them. In the subgroup where the tumour was located higher than 4 cm from the anal verge, sphincter-preserving surgery was performed in 95%. The follow-up period ranged from 10 to 49 months, with a median of 25 months. Local recurrences were observed in 4% of patients. Anorectal dysfunction caused impairment of social life in 40% of patients and 18% admitted that their quality of life was seriously affected - however, none of them stated that they would have preferred a colostomy. These preliminary data suggest that following high dose per fraction short-term preoperative radiotherapy a high rate of sphincter-preserving surgery can be reached, with acceptable anorectal function and an acceptable rate of local failure and late complications. The results of our own data and literature review indicate the need for a randomized clinical trial comparing high dose per fraction preoperative radiotherapy with immediate surgery with conventional preoperative radiochemotherapy with delayed surgery.

    Tolerance of the anal canal tends to be ignored in patients with cervical cancer undergoing whole pelvic radiotherapy. However, patients with hemorrhoids may be troubled with low radiation dose. We tried to analyze the dose-volume statistics of the anal canal in patients undergoing whole pelvic radiotherapy. The records of 31 patients with cervical cancer who received definite or postoperative radiotherapy at one institution were reviewed. Acute anal symptoms, such as anal pain and bleeding, were evaluated from radiotherapy start to 1 month after radiotherapy completion. Various clinical and dosimetric factors were analyzed to characterize relations with acute anal complications. The anal verge was located an average of 1.2 cm (range -0.6~3.9) below the lower border of the ischial tuberosity and an average of 2.7 cm (range -0.6~5.7) behind the sacral promontory level. The presence of hemorrhoids before radiotherapy was found to be significantly associated with acute radiation-induced anal symptoms (p = 0.001), and the mean induction dose for anal symptoms was 36.9 Gy. No patient without hemorrhoids developed an anal symptom during radiotherapy. Dosimetric analyses of V30 and V40 showed marginal correlations with anal symptoms (p = 0.07). The present study suggests a relation between acute anal symptoms following radiotherapy and acute hemorrhoid aggravation. Furthermore, the location of the anal verge was found to be variable, and consequently doses administered to the anal canal also varied substantially. Our results caution careful radiation treatment planning for whole pelvic radiotherapy, and that proper clinical management be afforded patients with hemorrhoids during radiotherapy.

    Abstract Controversy remains regarding whether preoperative chemoradiation protocol should be applied uniformly to all rectal cancer patients regardless of tumor height. This pooled analysis was designed to evaluate whether preoperative chemoradiation can be safely omitted in higher rectal cancer. An international consortium of 7 institutions was established. A review of the database that was collected from January 2004 to May 2008 identified a series of 2102 patients with stage II/III rectal or sigmoid cancer (control arm) without concurrent chemoradiation. Data regarding patient demographics, recurrence pattern, and oncological outcomes were analyzed. The primary end point was the 5-year local recurrence rate. The local relapse rate of the sigmoid colon cancer (SC) and upper rectal cancer (UR) cohorts was significantly lower than that of the mid/low rectal cancer group (M-LR), with 5-year estimates of 2.5% for the SC group, 3.5% for the UR group, and 11.1% for the M-LR group, respectively. A multivariate analysis showed that tumor depth, nodal metastasis, venous invasion, and lower tumor level were strongly associated with local recurrence. The cumulative incidence rate of local failure was 90.6%, 92.5%, and 94.4% for tumors located within 5, 7, and 9 cm from the anal verge, respectively. Routine use of preoperative chemoradiation for stage II/III rectal tumors located more than 8 to 9 cm above the anal verge would be excessive. The integration of a more individualized approach focused on systemic control is warranted to improve survival in patients with upper rectal cancer. PMID:27258487

    Background: The improvement in surgical techniques alongside neoadjuvant chemo radiation enabled more patients with low rectal cancer to have sphincter preservation. Study aim: To compare the oncologic and functional outcome in patients with locally advanced low rectal cancer treated by neoadjuvant chemo radiation followed by sphincter saving resection (SSR) against those who underwent abdomino-perineal resection (APR). Patients and methods: A total of 111 patients with low rectal cancer were included in the study. Sixty-one consented patients who prospectively underwent SSR, from Jan 2008 to Jan 2013, and a retrospective group, formed of 50 patients, selected from cases seen at NCI, with comparable demographic, clinical and pathologic criteria, who underwent APR from Jan 2003 to Jan 2008. All lesions were <5 cm from anal verge. All 111 patients received preoperative chemo radiation and total mesorectal excision. Results: All tumors were located at a median of 3.6 cm (range 2.5-4.5 cm) for the SSR group, and 3.5 cm (range 2.5-4.6 cm) for the APR group, from the anal verge. The median follow-up was 34 months (range 1-60 months) for both groups. The difference in disease recurrence and OS between the APR and SSR groups were both statistically insignificant. Conclusion: In low rectal cancer, the sphincter preservation appears to have nearly the same oncologic outcome compared to APR, this might be attributed to the small sample size and short follow up period. However, patients with sphincter preservation have certainly demonstrated an indisputable better functional outcome, in terms of stoma avoidance and adequate continence.

    The release of pollutant metals from petroleum industry in to ecosystems represents a serious hazard for the biosphere, because of their toxicity. The objective of this study was to determine the levels of some elements in petroleum sludge and scales collected from petroleum production area in Heglig oil field located in South Kordofan State. The concentration of Ca, Fe, V, Mn,Ni, Cu, Zn, Cs, Sr, Zr, Y and Pb in sludge and scale samples have been determined using energy dispersive x-ray fluorescence (EDXRF) equipped with a point source of 1 09C d. The concentration of Ca and Fe in scale samples were found to fall in range of 15,49-23.28% and 0.98-5.13%, respectively. The a verge elemental concentrations of Ti, Mn, Ni, Cu, Zn, Sr,Y, and Pb in scale samples were 2917.8, 567.74, 23.21, 23.05, 101.67, 31.38, 177.06 and 24.12 (mg/kg), respectively. The concentrations of Ca and Fe in sludge samples ranged from 1.98-8.82% and 0.71-5.19%, respectively and the a verge elemental concentrations of Cs, V, Mn,Cu, Zn, Pb, Sr, Y and Zr were 7.44, 92,59, 557.36, 7.67, 162.72,28.67, 65.02, 45.64 and 52.15 (mg/kg), respectively. Correlation analysis revealed lock of any significant correlation between elemental concentrations in sludge and scales. (Author)

    The purpose of the study reported here was to evaluate the potential impact of the tension of pelvic muscles on set-up errors. Twenty-nine consecutive patients with rectal cancer were included. The treatment simulation of the lateral beam in prone position was performed twice-with relaxed and next with maximally tense pelvic muscles. During the second simulation, the couch was moved so as to align the centre of the beam with the actual position of the skin mark tattooed during the first simulation. The bony landmarks on both images of corresponding lateral fields were matched. The beam's centre displacement and the rotation were measured using the beam image taken in relaxed position as a reference. The absolute values were used in calculation of the mean. For the anterior-posterior direction, the mean value of displacements was 15.3 mm, standard deviation (SD) 6.9 mm and the maximal value 37 mm. For the cranial-caudal direction, the mean value was 4.4 mm, SD 4 mm and the maximal value 17 mm. The mean rotation of the pelvis was 5.3 degrees, SD 2.4 degrees and maximal rotation 11 degrees. The majority of displacements were in the posterior (86%) and caudal (55%) directions. The majority of rotations were clockwise (76%). It was shown that pelvic muscle tension was the reason for anal verge displacements and mispositionings of the shielding block. This results in set-up inaccuracy, especially in the anterior-posterior direction, shielding block mispositioning and anal verge displacement

    Full Text Available A pesar del papel teórico que desempeñan las conductas de comprobación corporal en el proceso de mantenimiento de la conducta de atracón, los mecanismos por los que pueden afectar a los atracones siguen sin estar claros. Tomando el modelo de la objetivación de la patología alimentaria como marco teórico, los autores examinaron las posibles funciones que desempeñan la vergüenza corporal, la ansiedad por la apariencia y la restricción alimentaria en la comprobación del cuerpo y los atracones. Los datos recogidos en una amplia muestra de pacientes con trastorno de tipo bulímico en busca de tratamiento (N = 801 se analizaron a través de modelos de ecuaciones estructurales. Los resultados mostraron que, independientemente de las categorías diagnósticas específicas del DSM-5, las conductas de comprobación estaban asociadas indirectamente con los atracones y la restricción alimentaria a través de la vergüenza corporal y la ansiedad por la apariencia, mientras que la restricción alimentaria estaba directamente asociada con los atracones. Los resultados aportan utilidad clínica dado que contribuyen a la idea de cómo el examen crítico del propio cuerpo puede afectar de forma indirecta a las conductas de atracón. Se discuten las implicaciones prácticas de los hallazgos.

    Post-amalgamation depositional basins Asir tectonic terrane. The Hammamat PADB is investigated in Wadi Umm Gheig, Wadi Allaqi and Wadi Hodein in the Egyptian Eastern Desert tectonic terrane. It is supposed that the Fatima is a basin controlled by dextral transcurrent shearing occurred along the NE-oriented Wadi Fatima Shear Zone and the Ablah is a strike-slip pull-apart basin, and both basins were believed to be deposited during and soon after the Nabitah Orogeny (680-640 Ma) that marked suturing of the Afif terrane with the oceanic ANS terranes to the west. They were affected by at least three Neoproterozoic deformation phases and show geometric and kinematic relationships between folding and thrusting. The Hammamat PADB is a fault-bounded basin affected by a NW-SE- to NNW-SSE-oriented shortening phase just after the deposition of the molasse sediments, proved by NW- to NNW-verging folds and SE- to SSE-dipping thrusts that were refolded and thrusted in the same direction. The shortening phase in the Hammamat was followed by a transpressional wrenching phase related to the Najd Shear System, which resulted in the formation of NW-SE sinistral-slip faults associated with positive flower structures that comprise NE-verging folds and SW-dipping thrusts. Strain results in the three studied PADBs are nearly consistent, indicating that they are correlated and underwent the same history of deformation. The ANOVA test indicates that there is no significant difference for the Vector mean and ISYM for the three PADBs. There is only a significant difference for the Harmonic mean (P-value < 0.05). A Post Hoc test (Shefee) shows that the difference exists between the Allaqi and the Umm Gheig's deformed polymictic conglomeratic pebbles of the Hammamat PADB.

    Informal urban green-space (IGS) such as vacant lots, brownfields and street or railway verges is receiving growing attention from urban scholars. Research has shown IGS can provide recreational space for residents and habitat for flora and fauna, yet we know little about the quantity, spatial distribution, vegetation structure or accessibility of IGS. We also lack a commonly accepted definition of IGS and a method that can be used for its rapid quantitative assessment. This paper advances a definition and typology of IGS that has potential for global application. Based on this definition, IGS land use percentage in central Brisbane, Australia and Sapporo, Japan was systematically surveyed in a 10×10 km grid containing 121 sampling sites of 2,500 m2 per city, drawing on data recorded in the field and aerial photography. Spatial distribution, vegetation structure and accessibility of IGS were also analyzed. We found approximately 6.3% of the surveyed urban area in Brisbane and 4.8% in Sapporo consisted of IGS, a non-significant difference. The street verge IGS type (80.4% of all IGS) dominated in Brisbane, while lots (42.2%) and gaps (19.2%) were the two largest IGS types in Sapporo. IGS was widely distributed throughout both survey areas. Vegetation structure showed higher tree cover in Brisbane, but higher herb cover in Sapporo. In both cities over 80% of IGS was accessible or partly accessible. The amount of IGS we found suggests it could play a more important role than previously assumed for residents' recreation and nature experience as well as for fauna and flora, because it substantially increased the amount of potentially available greenspace in addition to parks and conservation greenspace. We argue that IGS has potential for recreation and conservation, but poses some challenges to urban planning. To address these challenges, we propose some directions for future research.

    The Anaximander Mountains are enigmatic highs located at the complex corner that links the Cyprus and Hellenic Arcs in the eastern Mediterranean. They are made up of several different highs: Anaximander (sensu stricto), Anaxagoras and Anaximenes. Previous work had shown that rock samples from the Anaximander Mountain have affinity with rocks exposed on land nearby in southern Turkey. This had been explained by rifting of the Mountain away from Turkey. In contrast to that, our interpretation of around 1750 km of high-resolution multi-channel seismic reflection data acquired in 2001 showed that Anaximander Mountain is part of a broadly south-verging Miocene thrust system associated with relative southward motion of the Tauride Mountains in southern Turkey. Post-Miocene motion also involves thrusting but is accompanied by transpression and rotation. The 3-dimensional nature of the geology makes mapping of the linkage of structures difficult, so we collected an additional 500 km of multi-channel seismic reflection data acquired in 2007, extending our 2001 survey further southwards into the Mediterranean Ridge. These new profiles are shot in a grid oblique to that obtained in 2001, such that the new profile intersections provide a basis for better correlation of the earlier data. We are testing our earlier interpretation through processing and interpretation of these new profiles. Here, we present examples of the new profiles and give first indications of how our earlier interpretation is broadly corroborated by the new data, but with minor adjustments. Anaximenes Mountain is imaged to the south of our previously- mapped area and is characterized as a large south-verging thrust lifting pre-Messinian strata by up to 2 km in a 12-km wide pop-up structure. Internally, Anaximenes is dissected by several splays from the bounding thrusts.

    To evaluate the impact of four different rectum contouring techniques and rectal toxicities in patients with treated with 3D conformal radiotherapy (3DCRT). Clinical and dosimetric data were evaluated for 94 patients who received a total dose 3DCRT of 70 Gy, and rectal doses were compared in four different rectal contouring techniques: the prostate-containing CT sections (method 1); 1 cm above and below the planning target volume (PTV) (method 2); 110 mm starting from the anal verge (method 3); and from the anal verge to the sigmoid flexure (method 4). The percentage of rectal volume receiving RT doses (30–70 Gy) and minimum, mean rectal doses were assessed. Median age was 69 years. Percentage of rectal volume receiving high doses (≥ 70 Gy) were higher with the techniques that contoured smaller rectal volumes. In methods 2 and 3, the percentage of rectal volume receiving ≥ 70 Gy was significantly higher in patients with than without rectal bleeding (method 2: 30.8% vs. 22.5%, respectively (p = 0.03); method 3: 26.9% vs. 18.1%, respectively (p = 0.006)). Mean rectal dose was significant predictor of rectal bleeding only in method 3 (48.8 Gy in patients with bleeding vs. 44.4 Gy in patients without bleeding; p = 0.02). Different techniques of rectal contouring significantly influence the calculation of radiation doses to the rectum and the prediction of rectal toxicity. Rectal volume receiving higher doses (≥ 70 Gy) and mean rectal doses may significantly predict rectal bleeding for techniques contouring larger rectal volumes, as was in method 3

    At several localities around the world, thrust belts have developed on both sides of oceanic island arcs (e.g., Java-Timor, Panama, Vanuatu, and the northeastern Caribbean). In these localities, the overall vergence of the backarc thrust belt is opposite to that of the forearc thrust belt. For example, in the northeastern Caribbean, a north-verging accretionary prism lies to the north of the Eastern Greater Antilles arc (Hispaniola and Puerto Rico), whereas a south-verging thrust belt called the Muertos thrust belt lies to the south. Researchers have attributed such bivergent geometry to several processes, including: reversal of subduction polarity; subduction-driven mantle flow; stress transmission across the arc; gravitational spreading of the arc; and magmatic inflation within the arc. New observations of deformational features in the Muertos thrust belt and of fault geometries produced in sandbox kinematic models, along with examination of published studies of island arcs, lead to the conclusion that the bivergence of thrusting in island arcs can develop without reversal of subduction polarity, without subarc mantle flow, and without magmatic inflation. We suggest that the Eastern Greater Antilles arc and comparable arcs are simply crustalscale bivergent (or "doubly vergent") thrust wedges formed during unidirectional subduction. Sandbox kinematic modeling suggests, in addition, that a broad retrowedge containing an imbricate fan of thrusts develops only where the arc behaves relatively rigidly. In such cases, the arc acts as a backstop that transmits compressive stress into the backarc region. Further, modeling shows that when arcs behave as rigid blocks, the strike-slip component of oblique convergence is accommodated entirely within the prowedge and the arc-the retrowedge hosts only dip-slip faulting ("frontal thrusting"). The existence of large retrowedges and the distribution of faulting in an island arc may, therefore, be evidence that the arc is

    Vegetation communities along recreational tracks may suffer from substantial edge-effects through the impacts of trampling, modified environmental conditions and competition with species that benefit from disturbance. We assessed impacts on trackside vegetation by comparing high and low usage tourism sites at a 1-10 m distance from recreational tracks in a popular arid-lands tourism destination in South Australia. The central aim was quantification of the strengths and spatial extent of tourism impacts along recreational tracks with a qualitative comparison of roads and trails. Track-distance gradients were most prevalent at high usage sites. There, species community composition was altered, total plant cover decreased, non-native species cover increased, plant diversity increased or decreased (depending on the distance) and soil compaction increased towards recreational tracks. Roadside effects were greater and more pervasive than trailside effects. Further, plant diversity did not continuously increase towards the road verge as it did along trails but dropped sharply in the immediate road shoulder which indicated high disturbance conditions that few species were able to tolerate. To our knowledge, we are the first to demonstrate that the access mode to a recreation site influences the potential of certain impacts, such as the increase of non-native species, to self-perpetuate from their points of introduction to disjointed sites with a predisposition to disturbance. Due to this propulsion of impacts, the overall spatial extent of roadside impacts was far greater than initially apparent from assessments at the road verge. We discuss possible means of mitigating these impacts. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The paper presents an overview of the phenomenon of range expanding of birds located at the northeastern limit of their range. The study area is located in the Volga-Kama Krai in the Chuvash Republic, adjacent to the River Volga. It is situated northwards and southwards of 56° N, and westwards and eastwards of 49° E, in a band of about 400 km. The problem is considered in aspect of the intra-century changes of climatic conditions in the region and in European Russia as a whole. The analysis of the relationship between the range expansion of some bird species and the intra-century climate changes was based on ornithological and climatological material available for the study area. We have used material on climate change in the Chuvashian Republic and Volga-Kama Krai since 1926, taking into account recent data of Roshydromet and Intergovernmental Panel on Climate Change. The idea of this study was based on the theory of climatic cycles of different periodicity, the theory of recent global climate change and the hypothesis of cyclic dynamics of the ranges of waterfowl in the context of centuries-old and intra-century climate change in Northern Eurasia. In the framework of the problem, we have studied ornithological material dated from the late 19th till the early 21st century, authored by Bogdanov, Ruzsky, Zhitkov, Buturlin, Artobolevsky, Volchanetsky, Pershakov, Popov, Glushenkov and others. As shown the intra-century climate changes do quite likely affect the northward and northeastward range expansion of such bird species as Cygnus olor, Anas strepera, Aythya ferina, Hieraaetus pennatus, Aquila heliaca, and Fulica atra. Climate changes can also be judged on the base of the shift in the arrival timing to earlier dates for some birds. It is most clearly manifested for early arriving species (Grus grus, Ardea cinerea, Actitis hypoleucos. It is also true for the later arriving Pernis apivorus and Merops apiaster whose existence depends on the

    Full Text Available The basic premise of my research regarding the fashion production of Sirogojno style was that „objects are, like words, carriers of information“. Based on research published so far – a paper by Bojana Bogdanovic being the most detailed – and my own fieldwork conducted in 2010, I have attempted to ascertain the extent to which this particular style of fashion carried information about the cultural environment which it represented. The research encompasses the study of the materials being used, the production and the sale of products made of wool. The development of this particular style was influenced by the enthusiasm of designer Dobrila Vasiljevic-Smiljanic and the women of the mt. Zlatibor region, as well as the support provided by the political structure of the period, the local government, and through Dobrila Vasiljevic-Smiljanic’s family ties – the church. Her creations are famous for incorporating adapted local ornaments. A distinct and recognizable style of woolen products was created. This „Wool Road“ – from using local raw materials to materials imported from Iceland, from creating unique motifs to sale in the open, from national and international sales to musealized sales in the first decade of the 21st century – has lasted for over fifty years. Products from Sirogojno were renowned both in the country and abroad. All the negative processes which happened during the nineties influenced the decline of production and distribution of hand-crafted products from Sirogojno. In the late 1990’s, the production was acquired by a local owner who didn’t show much interest in it. This production has been musealized in the first decade of the 21st century. Dobrila Vasiljevic-Smiljanic told me in 2010 that „everything should be started from scratch now, from new motifs to new marketing“. The new owners of the firm say that „the villages are deserted and there aren’t enough weavers“. On the other hand, there is sale

    Phenomena that are critical-systems verging on criticality with 'butterfly wings' sensitivity are common - the weather, climate change; stellar radiation; the New York Stock Exchange; population explosions; population collapses; the life cycle of fruit-flies; and many more. It must be expected that the Earth, an archetypal complex heterogeneous interactive phenomena, is a critical-system, hence there is a New Geophysics imposing fundamentally new properties on conventional sub-critical geophysics. We shall show that, despite shear waves and shear-wave splitting (SWS) being observationally neglected, azimuthally-varying stress-aligned SWS is nearly universally observed throughout the Earth's crust and uppermost ~400km of the mantle. Caused by stress-aligned fluid-saturated microcracks (intergranular films of hydrolysed melt in the mantle), the microcracks are so closely-spaced that they verge on failure in fracturing and earthquakes. Phenomena that verge on failure in this way are critical-systems which impose a range of fundamental-new properties on conventional sub-critical geophysics including: self-similarity; monitorability; calculability; predictability; controllability; universality; and butterfly wings' sensitivity. We shall show how these phenomena have been consistently observed along millions of source-to-receiver ray paths confirming the New Geophysics. New Geophysics helps to explain many otherwise inexplicable observations including a number of geophysical conundrums such as the Gutenberg-Richter relationship which is used to describe the behaviour of conventional classic geophysics despite being massively non-linear. The great advantage of the critical Earth is that, unlike other critical-systems, the progress towards criticality can be monitored at almost any point within the deep interior of the material, by analysing observations of seismic SWS. This gives an unrivalled understanding of the detailed behaviour of a particular critical-system. This

    En el presente estudio, se exploran las atribuciones de emociones morales de los adolescentes, ante una historia de maltrato entre iguales en el contexto escolar. Con ese objetivo, les preguntamos a cerca de los sentimientos de culpa, vergüenza, orgullo e indiferencia de agresores, víctimas y espectadores y les pedimos que justificaran la atribución de los mismos. Procuramos además saber si en términos de su experiencia personal se identifican o se desvinculan de cualquiera de ellos. Participaron un total de 1.237 preadolescentes y adolescentes españoles y portugueses de edades comprendidas entre los 11 y los 16 años. Para el estudio diseñamos el cuestionario SCAN-Bullying 2005 con soporte gráfico (conjunto de viñetas que representan una historia típica de maltrato entre iguales en el contexto escolar. Los resultados muestran un patrón emocional diferente en función del rol: orgullo e indiferencia fueron las emociones más atribuidas a los agresores, inversamente la vergüenza fue la emoción más atribuida a la víctima, mientras que la indiferencia, vergüenza y culpa se atribuyeron en porcentajes muy semejantes a los espectadores. La investigación se inscribe en el cuadro teórico de estudios anteriores que analizan el fenómeno del agresor feliz y de la desvinculación moral, y a la luz de este encuadramiento teórico, procuraremos discutir los resultados.

    In 2000 a field study was conducted at four different locations concerning the effects of low dosages of glufosinate-ammonium, a leaf acting herbicide, on off crop vegetation. Therefore species rich road verges and ditch banks not adapted to a history of herbicide use were sprayed twice with different dosages of glufosinate-ammonium, simulating drift (0, 2, 4, 16, 32 and 64% of the maximum field dose: 800 g a.i./ha). The parameters studied were short term phytotoxic effects and the effects on biomass, species cover and number of species in autumn (Braun-Blanquêt relevés). The results show significant phytotoxic effects at all dosages of glufosinate-ammonium on the non-target vegetation. The low concentrations (2 and 4%) had most impact when applied early in the season (9% average at the 2% dosage and 22% at 4% dosage, after the first spraying. At high dosages (32 and 64%) a decrease of the biomass of the vegetation was found in August. A comparison between treatments in August shows a small decrease in species number and cover in the 64% compared to the control. In the comparison between the spring and August relevés, the decrease in the mean number of species was significantly stronger in the treated plots than in the untreated ones of 4% and higher. For monocotyledons in all treatments except 16%, a significantly stronger decrease in species number was found compared to the untreated. For dicotyledons only the 64% dosage differed from the untreated. Only at the 64% treatment the total cover of species decreased more than in the untreated plots. Since drift percentages of 2-4% can be expected at 1-2 m from a treated plot it can be concluded that the use of glufosinate-ammonium could result in visible short term phytotoxic effects (max 22%) on off-crop vegetation such as ditch banks and verges. There are also indications that effects on the number and cover of species in autumn can occur. Because in future glufosinate-ammonium could be used on a large scale in

    Full Text Available The technological civilization and information society give a lot of advantages to a modern man in various fields. However, at the same time, we do not see a decrease in hostility and injustice in the society. Moreover, technological progress has led to the fact that human civilization is on the verge of a serious challenge caused by environmental disasters and opportunity for unprecedented disastrous consequences of the World War III. In these circumstances, the search for the causes of the current crisis is actual as well as the development of concepts that can contribute to overcoming this crisis. One of the most promising theories in this context is the ethics of truth. In modern civilization the issue of the importance of truth is shifted to the periphery of the intellectual discourse. Modern civilization uses only substitutes of the issue. Veracity in science together with popular opinions in the field of information circulating are such substitutes of truth. However, these substitutes do not fully reflect the true contents of the truth issue. The truth is not confined to the veracity of a celebrity’s opinion. Analyzing the theories by H. Jonas, В. Hübner, V. Stepin and T. Voronina, the study argues that the processes of losing of the meaning of life are intensifying in the modern civilization. We argue that a lack of a proper attention in modern civilization to the issue of truth inevitably stimulates processes of diluting the meaning of human life. Based on the theories by G. Hegel, H.-G. Gadamer and J. Neidleman T. Osborne, the study demonstrates that without thinking about the issue of the truth one cannot come near to the transcendent, and thus, his life could not be convincingly endowed with meaning, fullness and a purpose of existence. Understanding the issue of truth is especially important in conditions of the modern civilization, because our civilization is facing the possibility of self-destruction as a result of its

    G0.253+0.016 is a molecular clump that appears to be on the verge of forming a high-mass cluster: its extremely low dust temperature, high mass, and high density, combined with its lack of prevalent star formation, make it an excellent candidate for an Arches-like cluster in a very early stage of formation. Here we present new Atacama Large Millimeter/Sub-millimeter Array observations of its small-scale (∼0.07 pc) 3 mm dust continuum and molecular line emission from 17 different species that probe a range of distinct physical and chemical conditions. The data reveal a complex network of emission features with a complicated velocity structure: there is emission on all spatial scales, the morphology of which ranges from small, compact regions to extended, filamentary structures that are seen in both emission and absorption. The dust column density is well traced by molecules with higher excitation energies and critical densities, consistent with a clump that has a denser interior. A statistical analysis supports the idea that turbulence shapes the observed gas structure within G0.253+0.016. We find a clear break in the turbulent power spectrum derived from the optically thin dust continuum emission at a spatial scale of ∼0.1 pc, which may correspond to the spatial scale at which gravity has overcome the thermal pressure. We suggest that G0.253+0.016 is on the verge of forming a cluster from hierarchical, filamentary structures that arise from a highly turbulent medium. Although the stellar distribution within high-mass Arches-like clusters is compact, centrally condensed, and smooth, the observed gas distribution within G0.253+0.016 is extended, with no high-mass central concentration, and has a complex, hierarchical structure. If this clump gives rise to a high-mass cluster and its stars are formed from this initially hierarchical gas structure, then the resulting cluster must evolve into a centrally condensed structure via a dynamical process

    The ingress of particulate material into freshwater spawning substrates is thought to be contributing to the declining success of salmonids reported over recent years for many rivers. Accordingly, the need for reliable information on the key sources of the sediment problem has progressed up the management agenda. Whilst previous work has focussed on apportioning the sources of minerogenic fine sediment degrading spawning habitats, there remains a need to develop procedures for generating corresponding information for the potentially harmful sediment-bound organic matter that represents an overlooked component of interstitial sediment. A source tracing procedure based on composite signatures combining bulk stable {sup 13}C and {sup 15}N isotope values with organic molecular structures detected using near infrared (NIR) reflectance spectroscopy was therefore used to assess the primary sources of sediment-bound organic matter sampled from artificial spawning redds. Composite signatures were selected using a combination of the Kruskal–Wallis H-test, principal component analysis and GA-driven discriminant function analysis. Interstitial sediment samples were collected using time-integrating basket traps which were inserted at the start of the salmonid spawning season and extracted in conjunction with critical phases of fish development (eyeing, hatch, emergence, late spawning). Over the duration of these four basket extractions, the overall relative frequency-weighted average median (± 95% confidence limits) source contributions to the interstitial sediment-bound organic matter were estimated to be in the order: instream decaying vegetation (39 ± < 1%; full range 0–77%); damaged road verges (28 ± < 1%; full range 0–77%); septic tanks (22 ± < 1%; full range 0–50%), and; farm yard manures/slurries (11 ± < 1%; full range 0–61%). The reported procedure provides a promising basis for understanding the key sources of interstitial sediment-bound organic matter

    Full Text Available Con este estudio, resultado de una investigación empírica de carácter cualitativo, se pretende poner de relieve el desinterés que las ciencias sociales, y particularmente la sociología, han mostrado por la dimensión emocional de la sociabilidad. Este desinterés, que puede comprenderse como expresión del ethos cultural de la propia modernidad, resulta científicamente insostenible. De ahí que en los últimos años haya emergido con fuerza una corriente de pensamiento, y un campo de estudio específico, la sociología de las emociones, que pretende llenar este vacío. La investigación, partiendo del papel clave que el proceso comunicativo juega en la constitución del orden social, tal y como sostienen tanto el interaccionismo simbólico como la Teoría de Sistemas de N. Luhmann, pretende mostrar las funciones sociales que cumplen los contenidos emocionales presentes en la comunicación. Aplicando microanálisis del discurso a noticias publicadas en prensa escrita revela, pese al principio de "neutralidad afectiva" que debería orientar la "información" periodística, la abundante presencia de contenidos emocionales, revelando, al mismo tiempo, la imposibilidad de una adecuada interpretación del significado y sentido de una noticia, o de cualquier expresión comunicativa, si no se tiene en cuenta su estructura emocional. En el artículo se presenta la estructura emocional de una noticia, "el relato de un accidente de coche", en la que su sentido comunicativo y social se construye con una cadena de horror, de vergüenza y de preocupación. Aplicando al análisis de este artículo la metodología desarrollada por Thomas J. Scheff, que denomina part / whole analysis, se establecen conexiones entre esta cadena y la estructura vital de la sociedad posmoderna considerada en tanto sociedad del riesgo. Se sostiene que la sociedad contemporánea ya no puede basar su legitimidad en las metas, "positivas" que sostuvieron y animaron a la sociedad

    Using field data, balanced cross-sections, gravity and reprocessed seismic reflection data, a detailed structural study has been realized on the Salon-Cavaillon fault (SCF) area, in Provence region (SE France). This fault separates two main ridges (the Alpilles to the west and the Luberon to the east). Field data and balanced cross-sections allow us to characterize the present-day structures and the post-Oligocene deformation that significantly differ on either sides of the SCF. Our structural study shows a post-Oligocene southward displacement of the structures on the two sides of the SCF. The Luberon ridge is a fault propagation-fold developed on a S-verging ramp. The anticline is bent as a drag fold in the vicinity of the dextral strike-slip SCF. The Alpilles ridge is a less developed fault propagation fold. Its eastern termination was affected by a counter-clockwise rigid block rotation around a vertical axis. The differences between the two ridges in terms of structural architecture are explained by the deep geometry of their ramp, inherited from the Late Cretaceous to Middle Eocene Pyrenean tectonic phase. The décollement level is shallow to the western side of the SCF (2-3 km), probably in the Lower Cretaceous or Upper Jurassic marls, than in the eastern side, the fault is rooted in Triassic layers at a depth > 5 km. The deep rooting favoured a large-scale fault propagation type of folding, whereas shallow-seated rooting favoured a small-scale fault propagation type of folding and block rotations. To image the sub-surface structures to the west of the SCF, we also included gravity data and reprocessed seismic reflection. It allows us to refine the regional tectonic framework and to detect several hidden E-trending S-verging folds. The main shortening episode in Provence occurred during the Pyrenean phase, with 65% of the total shortening to the east of the SCF and 95% to the west. From the Miocene to the present, Alpine shortening decreases strongly to the

    The recent completion of a high-resolution aeromagnetic survey over the Pie de Palo uplift of the western Sierras Pampeanas has revealed an area of large magnetic anomalies associated with the Pie de Palo Complex. The Las Pirquitas thrust, which has transported and uplifted the Pie de Palo Complex, is recognized for at least 30 km in a roughly NE direction along the western boundary of the Pie de Palo Complex, beyond its limited outcrop. The type of sediments of the Caucete Group in the footwall of the Las Pirquitas thrust, which are regarded as the leading edge of the Precordillera terrane, are associated with much less pronounced magnetic anomalies. In addition, a conspicuous, NNE trending, broad magnetic high stands out in the survey, several kilometers to the east of the main outcrops of the Pie de Palo Complex; this broad magnetic anomaly bisects the Pie de Palo basement block, and continues further south at least as far as 32°S, the southern boundary of the latest aeromagnetic survey. This magnetic anomaly is interpreted to represent a structure corresponding to the Grenvillian Precordillera-Pie de Palo tectonic boundary zone, and would comprise the buried largest part of the mafic-ultramafic belt. The geophysical model of the magnetic data indicates that the boundary zone dips to the east, possibly suggesting the existence of a set of synthetic east dipping, west-verging thrusts, of which only one major structure (Las Pirquitas thrust) is exposed; the possibility of other slivers of upthrust boundary zone material cannot be excluded. It is considered that the Pie de Palo Complex represents a small sliver upthrust from the unexposed boundary zone material (containing highly magnetic mafic-ultramafic rocks). The east-dipping, west verging structures associated with the Pie de Palo Complex are suggested to represent an Ordovician reactivation of a Grenvillian suture zone developed when the Precordillera basement and Pie de Palo terrane docked; this

    The Andean foreland of western Argentina (28°S-33°S) corresponds to retroarc deformations associated with the ongoing flat subduction of the Nazca plate beneath the South American lithosphere, and associated with high levels of seismic activity and crustal active faulting. To improve earthquake source identification and characterization in the San Juan region, data from seismology, structural geology and quantitative geomorphology can be integrated and combined to provide a seismotectonic model. In this model, the Andean back-arc of western Argentina has to be regarded as an obliquely converging foreland where Plio-Quaternary deformations are partitioned between strike-slip and thrust motions that are localized on the E-verging, thin-skinned Argentine Precordillera, and the W-verging thick-skinned Sierras Pampeanas, respectively. In this domain, the Sierra Pie de Palo is a key structure playing a major role in the partitioning of the Plio-Quaternary deformations. Located in the westernmost Sierras Pampeanas, the Sierra Pie de Palo forms a NNE striking, 80 km-long and 35-40 km-wide, ellipsoid range that reaches elevation as high as 3162 m. This mountain range is an actively growing basement fold associated with a high level of seismic activity (e.g., the November 23, 1977, Caucete, Mw 7.4 earthquake). To evaluate the degree of tectonic activity around the Sierra Pie de Palo, we combined a detailed morphometric analysis of the topography together with in situ-produced cosmogenic 10Be concentrations measured in (1) bedrock outcrops corresponding to the exhumed erosional regional surface, (2) surface boulders abandoned on alluvial fans deformed by active faults, and (3) in fluvial sediments sampled at the outlets of selected watersheds that drains out from the Sierra Pie de Palo. All together, our results allows: (1) assessing quantitative constraints on the rate of tectonic and denudation processes that are responsible for the active growth and erosion of the Sierra

    The Matagusanos-Maradona-Acequión Valley sits within the Andes Precordillera fold-thrust belt of western Argentina. It is an elongated topographic depression bounded by the roughly N-S trending Precordillera Central and Oriental in the San Juan Province. Moreover, it is not a piggy-back basin as we could have expected between two ranges belonging to a fold-thrust belt, but a very active tectonic corridor coinciding with a thick-skinned triangular zone, squeezed between two different tectonic domains. The two domains converge, where the Precordillera Oriental has been incorporated to the Sierras Pampeanas province, becoming the western leading edge of the west-verging broken foreland Sierras Pampeanas domain. This latter province has been in turn incorporated into the active deformation framework of the Andes back-arc at these latitudes as a result of enhanced coupling between the converging plates due to the subduction of the Juan Fernández ridge that flattens the Nazca slab under the South American continent. This study focuses on the neotectonics of the southern tip of this N-S elongated depression, known as Acequión (from the homonym river that crosses the area), between the Del Agua and Los Pozos rivers. This depression dies out against the transversely oriented Precordillera Sur, which exhibits a similar tectonic style as Precordillera Occidental and Central (east-verging fold-thrust belt). This contribution brings supporting evidence of the ongoing deformation during the Late Pleistocene and Holocene of the triangular zone bounded between the two leading and converging edges of Precordillera Central and Oriental thrust fronts, recorded in a multi-episodic lake sequence of the Acequión and Nikes rivers. The herein gathered evidence comprise Late Pleistocene-Holocene landforms of active thrusting, fault kinematics (micro-tectonic) data and outcrop-scale (meso-tectonic) faulting and folding of recent lake and alluvial sequences. In addition, seismically

    Purpose: A major concern for lung intensity modulated radiation therapy delivery is the deviation of actually delivered dose distribution from the planned one due to simultaneous movements of multileaf collimator (MLC) leaves and tumor. For gated lung stereotactic body radiotherapy treatment (SBRT), the situation becomes even more complicated because of SBRT's characteristics such as fewer fractions, smaller target volume, higher dose rate, and extended fractional treatment time. The purpose of this work is to investigate the dosimetric effect of intrafraction tumor motion during gated lung SBRT delivery by reconstructing the delivered dose distribution with real-time tumor motion considered. Methods: The tumor motion data were retrieved from six lung patients. Each of them received three fractions of stereotactic radiotherapy treatments with Cyberknife Synchrony (Accuray, Sunnyvale, CA). Phase gating through an external surrogate was simulated with a gating window of 5 mm. The resulting residual tumor motion curves during gating (beam-on) were retrieved. Planning target volume (PTV) was defined as physician-contoured clinical target volume (CTV) surrounded by an isotropic 5 mm margin. Each patient was prescribed with 60 Gy/3 fractions. The authors developed an algorithm to reconstruct the delivered dose with tumor motion. The DMLC segments, mainly leaf position and segment weighting factor, were recalculated according to the probability density function of tumor motion curve. The new DMLC sequence file was imported back to treatment planning system to reconstruct the dose distribution. Results: Half of the patients in the study group experienced PTV D95% deviation up to 26% for fractional dose and 14% for total dose. CTV mean dose dropped by 1% with tumor motion. Although CTV is almost covered by prescribed dose with 5 mm margin, qualitative comparison on the dose distributions reveals that CTV is on the verge of underdose. The discrepancy happens due to tumor

    The purpose of this case study is to communicate a technique on treating the re-irradiation of squamous cell carcinoma (SCC) of anal canal with proton fields matched with electron fields to spare prostatic urethra. A 76-year old male presented with a secondary radiation-induced malignancy as a result of prostate brachytherapy seeds irradiation 10 years prior. A rectal examination revealed a bulky tumor at the top of the anal canal involving the left superior-most aspect of the anal canal extending superiorly into the rectum. The inferior extent was palpable approximately 3cm from the anal verge and the superior extent of the mass measured greater than 5cm in the superior-inferior dimension. Chemoradiation was suggested since the patient was opposed to abdominoperineal resection (APR) and colostomy. The use of proton therapy matching with electron fields in the re-irradiation setting could help reduce the complications. A 2 lateral proton beams were designed to treat the bulky tumor volume with 2 electron beams treating the nodal volumes. This complication of treatment fields helped spare the prostatic urethra and reduced the risk of urinary obstruction in the future. Copyright © 2016 American Association of Medical Dosimetrists.

    Full Text Available The distribution of crayfish in Europe is examined using information from a variety of sources mainly for the last two decades. All European countries have at least one indigenous crayfish species (ICS, many with large stocks, and most countries in Western Europe have at least one non-indigenous crayfish species (NICS. Some species termed indigenous in certain countries may have been introduced in relatively recent times. However, the meaning of the term indigenous (native varies between countries. NICS continue to expand their ranges and present a continued threat to ICS through competition and transmission of diseases, notably crayfish plague. The current high level of interest in crayfish means that many countries are monitoring their crayfish situation and, where necessary, taking steps to renew stocks of threatened indigenous species, some of which are apparently on the verge of extinction. A more regular monitoring programme for European crayfish as a whole is needed if the demise of indigenous species is to be prevented.

    Full Text Available The Subbetic sierras of Las Cabras to the Gibalto form an arched structure, giving it a high relief, constituted by many tectonic slices, verging to the South in its southern border and to the North and West in its concave border. Although it could be interpreted as an allochthonous structure, really is rooted in the transitional area between the Median and the Internal Subbetic. Several local factors have influenced this complex structure, but the final cause is the oblique collision (transpression of the In-ternal Zone against External Zone of the Betic Chain, producing an important strike-slip system.

    Las sierras subbéticas de las Cabras al Gibalto forman una estructura arqueada, que da un fuerte relieve, constituida por escamas tectónicas, vergentes al sur en su borde convexo, meridional, y al nor-te y oeste en su borde cóncavo. Aunque podría interpretarse como una estructura alóctona, se en-cuentra enraizada en el área de tránsito entre el Subbético Medio y el Interno. En su génesis han in-fluido varios factores locales pero la causa que controla a todos ellos es la colisión oblicua, en trans-presión, de la Zona Interna Bética contra la Externa, que produjo un importante sistema de desgarre.

    The kidneys receive approximately 25% of cardiac output, which is a prerequisite in order to maintain sufficient glomerular filtration rate. However, both intrarenal regional renal blood flow and tissue oxygen levels are heterogeneous with decreasing levels in the inner part of the medulla. These differences in combination with the heterogeneous metabolic activity of the different nephron segment located in the different parts of the kidney may constitute a functional problem when challenged. The proximal tubule and the medullary thick ascending limb of Henle are considered to have the highest metabolic rate, which is relating to the high mitochondria content needed to sustain sufficient ATP production from oxidative phosphorylation in order to support high electrolyte transport activity in these nephron segments. Interestingly, the cells located in kidney medulla functions at the verge of hypoxia and the mitochondria may have adapted to the surrounding environment. However, little is known about intrarenal differences in mitochondria function. We therefore investigated functional differences between mitochondria isolated from kidney cortex and medulla of healthy normoglycemic rats were estimated using high-resolution respirometry. The results demonstrate that medullary mitochondria had a higher degree of coupling, are more efficient and have higher oxygen affinity, which would make them more suitable to function in an environment with limited oxygen supply. Furthermore, these results support the hypothesis that mitochondria of medullary cells have adapted to the normal hypoxic in vivo situation as a strategy of sustaining ATP production in a suboptimal environment.

    Energy demand is increasing day by day because of the rapid developments in the population, industrialization and urbanisation. Since, fossil fuels will be at the verge of getting extinct, researches are mostly focused on the renewable sources, such as biomass, in recent years. This paper provides an environmentally friendly process to convert waste biomass samples to bio-oil and bio-char by pyrolysis. For this purpose, pyrolysis characteristics of pomegranate peels under inert atmosphere were studied by using both TGA to analysis decomposition behaviour and a batch reactor to investigate product yields and properties. The properties of bio-oil and bio-char were investigated by different analytical techniques such as GC-MS, FT-IR, SEM, He pycnometry and elemental analysis. As a consequence, it is possible to obtain bio-oil, which has similar properties like petroleum hydrocarbons, and to obtain bio-char, which can be further used as a solid fuel or a carbonaceous adsorbent material via pyrolysis process.

    Moard, D.M.; Cuzens, J.E.

    1998-07-01

    Energy deregulation, building design efficiency standards and competitive pressures all encourage the incorporation of distributed fuel cell cogeneration packages into modern buildings. The building marketplace segments to which these systems apply include office buildings, retail stores, hospitals, hotels, food service and multifamily residences. These applications represent approximately 60% of the commercial building sector's energy use plus a portion of the residential sector's energy use. While there are several potential manufacturers of fuel cells on the verge of marketing equipment, most are currently using commercial hydrogen gas to fuel them. There are few suppliers of equipment, which convert conventional fuels into hydrogen. Hydrogen Burner Technology, Inc. (HBT) is one of the few companies with a proven under-oxidized-burner (UOB) technology, patented and already proven in commercial use for industrial applications. HBT is developing a subsystem based on the UOB technology that can produce a hydrogen rich product gas using natural gas, propane or liquid fuels as the feed stock, which may be directly useable by proton exchange membrane (PEM) fuel cells for conversion into electricity. The combined thermal output can also be used for space heating/cooling, water heating or steam generation applications. HBT is currently analyzing the commercial building market, integrated system designs and marketplace motivations which will allow the best overall subsystem to be designed, tested and introduced commercially in the shortest time possible. HBT is also actively involved in combined subsystem designs for use in automotive and small residential services.

  14. Ten residual biomass fuels for circulating fluidized-bed gasification

    2001-07-01

    In co-operation with a Dutch company (NV Afvalzorg) and the Dutch agency for energy and environment (Novem), ECN has successfully tested 10 different biomass residues in its 500 kW{sub th} circulating fluidized-bed gasification facility. Among the fuels used as demolition wood (both puree and mixed with sewage sludge and paper sludge), verge grass, railroad ties, cacao shells and different woody fuels. Railroad ties turn out to contain very little (heavy) metals. Initially, fuel feeding problems often impeded smooth operation. Contrary to feeding systems, the circulating fluidized-bed gasification process itself seems very flexible concerning the conversion of different kinds of biomass fuels. The fuel moisture content is one of the most important fuel characteristics. More moisture means that more air is needed to maintain the process temperature resulting in better carbon conversion and lower tar emission but also lower product gas heating value and lower cold gas efficiency. So, for a good comparison of the gasification behaviour of different fuels, the moisture content should be similar. However, the moisture content should be defined on an ash-free basis rather than on total mass (the usual way). Some of the ashes produced and retained in the second cyclone were analysed both for elemental composition and leaching behaviour. It turned out that the leaching rate of Mo and Br, elements only present in small concentrations, are preventing the ash to be considered as inert material according to the Dutch legislation for dumping on landfill sites.

    2013-06-01

    Family caregivers' views and experiences related to treatment usage processes by their adult relatives with serious and persistent mental illness (SPMI) were empirically examined in a sample of Latino caregivers (n = 17) who were users of services at the National Alliance on Mental Illness (NAMI) in a predominantly Latino- (80%) and Mexican-descent large city in the Southwest United States. We conducted a stability check of qualitative findings with a second sample of Latino caregivers with no exposure to NAMI (n = 15). Overall, the combined sample (N = 32) compared similarly with larger samples of Latino adults and caregivers in quantitative measures of acculturation, familism, caregiver stigma, and depression symptoms. Together, caregivers' stigma and cultural beliefs, such as vergüenza (shame), use of folk healers, and lack of insurance, were major reported barriers to service usage. Family support (and lack of) for treatment also weighed heavily as a facilitator (and a barrier) of service usage, thus highlighting the complexity of family relationship contexts. Substantial portions of caregivers reported that treatment initiation was prompted by psychiatric hospitalization (50%), and that positive experiences with service providers were influential in treatment retention (72%). Given the high levels of family involvement reported among Latino caregivers, the findings underscore the potential role of family caregivers in treatment engagement and retention. Future research is needed that examines family caregivers' role in treatment with models that consider the interplay between cultural background, family level relationships, and service system contexts.

    Full Text Available There is given the forecast of development of one of the leading West European countries –Great Britainon the base of biosocial approach.The main fundamentals of this approach are:1. Political and ethnogenetic are interrelated, which suggests the existence of a single process of ethnopolygenesis.2. An ethnos in its development goes through a series of age-phases – stable periods and dividing them phase transitions – unstable crisis periods, characterized by distemper (amplitudinous domestic conflicts.3. The age range of phases and phase transitions of ethnogenesis and periods of crisis in some phases, similar in character to phase transitions are determined by a universal, invariant eras and types of polities regularity – numerical algorithm of ethnopolygenesis.4. The distempers and major military defeats mainly are characteristic for unstable periods.It is shown that the British ethnogenesis developed generally in accordance with the numerical algorithm: distemper in the political history ofEnglandtook place during the periods of unstable states of phase transitions and critical periods in phases. This same regularity is generally true of the major military defeats. It is shown that the British are on the verge of the beginning of one of the most painful unstable states. There is given the forecast ofEnglandon the basis of this conclusion.Conclusions of the article may be of interest for scientists involved in political forecasting and for politicians.DOI: http://dx.doi.org/10.12731/2218-7405-2013-2-32

    The geological heritage also indicated as `Geosites` or `Geotopes` in the `Area 4` defined in the Census Plan of Environmental and Cultural Heritage of Latium Region (Delivery R.C. n. 642/1979) in this paper is hereby described. In this area the Pontina and Fondi coastal plains, the Alban Hills Volcanic District Northward, the Mounts Volsci Range Eastward and Southward the Circeo Promontory is present. The geological context is described referring to the geomorphology and the landscape, the paleontology, the stratigraphy, the hydrogeology and the building materials. The museums set in the area also described. Geological history began during Upper Trias (Volsci Range and Circeo promontory) has continued until recent times (Pontina and Fondi plains and Alban Hills Volcanic District). The Mount Volsci Range is mostly constituted by carbonatic rocks (`Latium-Abruzzi series`) with shelf facies, ranging in age from the Upper Trias to the Paleocene, with scarce evidence of the Miocene transgression. From a structural point of view the Volsci chain shows main tectonic alignments trending NW-SE, NE-SW and N-S, folds and overthrusts verging NE.

    Objective: To evaluate the clinical factors associated with pathological complete response (pCR) after preoperative neoadjuvant chemoradiotherapy for rectal cancer. Methods: A retrospective analysis was performed on the clinical data of 116 patients with rectal cancer, who underwent neoadjuvant chemoradiotherapy followed by radical surgery from January 2009 to December 2012. All patients received pelvic intensity-modulated radiotherapy (50 Gy/25 fractions) with concurrent fluorouracil based chemotherapy and then underwent radical surgery 4-8 weeks later. The clinical factors associated with pCR or non-pCR were analyzed by Logistic regression. Results: Of the 116 patients, 20 (17.2%) achieved a pCR after neoadjuvant chemoradiotherapy. The univariate analysis showed that percentage of circumference of the rectal tube invaded by the tumor, preoperative serum carcinoembryonic antigen (CEA) level, T stage, N stage, distance from the anal verge, degree of tumor differentiation, and maximum tumor diameter were associated with pCR or non-pCR after neoadjuvant chemoradiotherapy for rectal cancer. The multivariate analysis revealed that percentage of circumference of the rectal tube invaded by the tumor, preoperative serum CEA level,and T stage were predictive factors for pCR or non-pCR after neoadjuvant chemoradiotherapy for rectal cancer. Conclusions: Non-circumferential tumor (percentage of circumference of the rectal tube invaded by the tumor <75 %), low CEA level, and early T stage before treatment may be associated with pCR after neoadjuvant chemoradiotherapy for rectal cancer.

  19. Créolité and Réunionese Maloya: From ‘in-between’ to ‘Moorings’

    Directory of Open Access Journals (Sweden)

    Stephen Muecke

    2012-06-01

    Full Text Available At the beginning of October 2009, UNESCO announced that the culture of maloya, a genre of song and dance from the island of Réunion, would henceforth become an international heritage item. The Geneva committee, in placing this endangered form of culture under their protection, defined it as a ‘type of music, song and dance native to the island of Réunion’. There is nothing unusual in the fact that a marginal item of ‘immaterial’ culture, originating from a tiny speck of France in the Indian Ocean, should be noticed by an international organisation and ‘protected’ in this way. This discussion paper investigates versions of creole and créolité and the role of theory in the kind of advocacy that promoted maloya. It argues that ‘moorings’ (Vergès and Marimoutou, as a concept for creolisation studies, is more robust, concrete and precise than Bhabha’s ‘in-between’.

    The purpose of this case study is to communicate a technique on treating the re-irradiation of squamous cell carcinoma (SCC) of anal canal with proton fields matched with electron fields to spare prostatic urethra. A 76-year old male presented with a secondary radiation-induced malignancy as a result of prostate brachytherapy seeds irradiation 10 years prior. A rectal examination revealed a bulky tumor at the top of the anal canal involving the left superior-most aspect of the anal canal extending superiorly into the rectum. The inferior extent was palpable approximately 3 cm from the anal verge and the superior extent of the mass measured greater than 5 cm in the superior-inferior dimension. Chemoradiation was suggested since the patient was opposed to abdominoperineal resection (APR) and colostomy. The use of proton therapy matching with electron fields in the re-irradiation setting could help reduce the complications. A 2 lateral proton beams were designed to treat the bulky tumor volume with 2 electron beams treating the nodal volumes. This complication of treatment fields helped spare the prostatic urethra and reduced the risk of urinary obstruction in the future.

    Full Text Available Treating cancer with vaccines has been a challenging field of investigation since the 1950s. Over the years, the lack of effective active immunotherapies has led to the development of numerous novel strategies. However, the use of therapeutic cancer vaccines may be on the verge of becoming an effective modality. Recent phase II/III clinical trials have achieved hopeful results in terms of overall survival. Yet despite these encouraging successes, in general, very little is known about the basic immunological mechanisms involved in vaccine immunotherapy. Gaining a better understanding of the mechanisms that govern the specific immune responses (i.e., cytotoxic T lymphocytes, CD4 T helper cells, T regulatory cells, cells of innate immunity, tumor escape mechanisms elicited by each of the various vaccine platforms should be a concern of cancer vaccine clinical trials, along with clinical benefits. This review focuses on current strategies employed by recent clinical trials of therapeutic cancer vaccines and analyzes them both clinically and immunologically.

    2015-01-01

    Freshwater mussels (Bivalvia: Unionoida) are highly imperiled with many species on the verge of local extirpation or global extinction. This study investigates patterns of genetic structure and diversity in six species of freshwater mussels in the central Great Lakes region of Ontario, Canada. These species vary in their conservation status (endangered to not considered at risk), life history strategy, and dispersal capabilities. Evidence of historical genetic connectivity within rivers was ubiquitous across species and may reflect dispersal abilities of host fish. There was little to no signature of recent disturbance events or bottlenecks, even in endangered species, likely as a function of mussel longevity and historical population sizes (i.e., insufficient time for genetic drift to be detectable). Genetic structure was largely at the watershed scale suggesting that population augmentation via translocation within rivers may be a useful conservation tool if needed, while minimizing genetic risks to recipient sites. Recent interest in population augmentation via translocation and propagation may rely on these results to inform management of unionids in the Great Lakes region.

    1988-12-01

    Although studies of orbital mechanics provide speculative notions of future climatic trends, they cannot predict how these trends will manifest themselves in the immediate area around Yucca Mountain. The generally accepted approach to this question is to consider the climatic variations that have occurred during the last 10,000 years, and use these as a guide to the likely range of future variation in climate. However, because climatic studies around the world indicate that we are potentially on the verge of another ice age, we should also consider the conditions that predominated during the Pleistocene. The specific aim of this project is to derive the climatic history of Yucca Mountain during the last 20,000 years from the vegetation history. By integrating data obtained from pollen records, woodrat dens (middens), and tree-ring sequences from the Nevada Test Site (NTS) area, a regional climatic record is being generated that can be correlated to data obtained at Yucca Mountain to formulate a local climatic sequence there. This will then be used to determine the magnitude and frequency of climatic variation that have occurred during that time at Yucca Mountain. These data can then be used by other researchers to provide estimates of rainfall, recharge and soil chemical changes for modeling the past hydrology of Yucca Mountain

    In the charmed particle studies using the bubble chamber at SLAC, more film was obtained. A measurement of the lifetimes of charmed mesons was published. The cascade experiment at BNL and the double-V experiment at Fermilab both saw great progress in refining data. Both of these efforts are on the verge of publication of results. The douple-phi experiment at Fermilab was run obtaining over three million triggers and a definite phi-phi signal, and advanced by construction efforts on a scintillator array to segment the Cherenkov counter, the signal processor electronics and the drift chambers. Theoretical work is continuing on the predictions of perturbative QCD. Leading and next-to-leading logarithm terms were investigated for deep inelastic Compton scattering. Scaling violations in deep inelastic scattering were analyzed. Calculations have been performed on gluon polarization in quark-gluon elastic scattering. Exclusive decays of J/psi were studied in an analysis to be expanded. Fourth-order QCD corrections to the longitudinal coefficient function in deep-inelastic scattering were calculated and published. A comparison was made between the principle of minimal sensitivity and other schemes for renormalization. Mathematical and physical problems concerning gravitation and general relativity continue to be investigated, especially questions of the possible time dependence of G, the gravitational constant

    2017-04-01

    Electroactivity was noticed early in biological substances, including proteins, polynucleotides and enzymes, even piezoand pyroelectricity were found in wool, hair, wood, bone and tendon. Recently, ferroelectricity has been identified in a surprisingly large number of biologically relevant materials, including hydroxyapatite, aortic walls and elastin. Inspired by the variety of natural electroactive materials, a wealth of new elastomers and polymers were designed recently, including an all organic elastomer electret and self-healing dielectric elastomers. Let's further draw inspiration from nature and widen the utilization of electroactive polymers towards (mobile) healthcare and biomedical applications. Ferroelectrets, internally charged polymer foams with a strong piezoelectric thickness coefficient are employed in biomedical sensing, for example as blood pressure and pulse sensor, as vital signs monitor or for the detection of tonicclonic seizures. Piezo- and pyroelectric polymers are booming in printed electronics research. They provide electronic skin the ability to "feel" pressure and temperature changes, or to generate electrical energy from vibrations and motions, even from contractile and relaxation motions of the heart and lung. Dielectric elastomers are pioneered by StretchSense as wearable motion capture sensors, monitoring pressure, stretch, bend and shear, quantifying comfort in sports and healthcare. On the cellular level, electroactive polymer arrays are used to study mechanotransduction of individual cells. Ionic electroactive polymers show potential to be used in implantable electroactive biomedical devices. Already with the currently available science and technology, we are at the verge of witnessing the demonstration of truly complex bionic systems.

    Full Text Available Urban ecosystem health evaluation can assist in sustainable ecological management at a regional level. This study examined urban agglomeration ecosystem health in the middle reaches of the Yangtze River with entropy weight and extension theories. The model overcomes information omissions and subjectivity problems in the evaluation process of urban ecosystem health. Results showed that human capital and education, economic development level as well as urban infrastructure have a significant effect on the health states of urban agglomerations. The health status of the urban agglomeration’s ecosystem was not optimistic in 2013. The majority of the cities were unhealthy or verging on unhealthy, accounting for 64.52% of the total number of cities in the urban agglomeration. The regional differences of the 31 cities’ ecosystem health are significant. The cause originated from an imbalance in economic development and the policy guidance of city development. It is necessary to speed up the integration process to promote coordinated regional development. The present study will aid us in understanding and advancing the health situation of the urban ecosystem in the middle reaches of the Yangtze River and will provide an efficient urban ecosystem health evaluation method that can be used in other areas.

  10. Passive houses in Norway

    Energy Technology Data Exchange (ETDEWEB)

    Halse, Andreas

    2008-12-15

    The paper analyzes the introduction of passive houses in the Norwegian house market. Passive houses are houses with extremely low levels of energy consumption for heating, and have not yet been built in Norway, but have started to enter the market in Germany and some other countries. The construction sector is analyzed as a sectoral innovation system. The different elements of the innovation system are studied. This includes government agencies, producers, consumers, finance and education. The analysis shows that passive and low-energy houses are on the verge of market breakthrough. This can partly be explained by economic calculations, and partly by processes of learning and change in the institutional set-up of the sector. The construction sector is a sector characterized by low innovative intensity and little interaction between different agents. Those working to promote passive houses have to some extent managed to cope with these challenges. This has happened by breaking away from the traditional focus of Norwegian energy efficiency policies on technology and the economically rational agents, by instead focusing on knowledge and institutional change at the level of the producers.

    Full Text Available The purpose of this study was to examine the association between attachment styles and stigma in adults. Participants were 361 adults (186 females and 175 males aged between 18 and 69 (M=31.77, SD=9.45. Participants completed the measurement instruments for determining their stigmatizing tendencies and attachment styles. Study results showed that, stigma tendencies of people with the secure attachment style are lower for the discrimination and exclusion, prejudgment and psychological health dimensions, and are higher for people with the fearful attachment style for the discrimination and exclusion, labeling and psychological health dimensions. Preoccupied and dismissive attachment styles are also positively associated with prejudgment tendency. Finally, stigma tendencies of males are more likely to be higher than females for the discrimination and exclusion, labeling and psychological health dimensions. Because different attachment styles are related variously to the subscales of stigma in this study, interventions to decrease stigma of individuals can verge to enhancing the quality of mother-child interactions.

    As oil deposits are limited, it is very important to develop techniques for manufacturing petroleum alternatives as substitute energy sources to brighten the outlook for the future. The Research Association for Petroleum Alternatives Development (RAPAD) in Japan is engaged in the research and development of production techniques for light hydrocarbon oils such as gasoline, kerosene, and light oil from synthesis gas (CO, H/sub 2/) obtained from the raw materials of natural gas, coal, etc. Regarding the MTG process of synthesizing gasoline via methanol from synthesis gas and the STG process of directly synthesizing gasoline from synthesis gas, Cosmo Oil Co., Ltd. and Mitsubishi Heavy Industries, Ltd., members of RAPAD, have sought jointly to develop catalysts and processes. As a result of this co-operation, the authors have recently succeeded in developing a new catalyst with a long life span capable of providing a high yield and high selectivity. Additionally, the authors are currently on the verge of putting into effect a unique two-step STG process of synthesizing high octane gasoline via dimethyl ether, referred to as the AMSTG process.

    The conversion of wastes into energy and the protection of the environment are major concerns today. With mounting environmental pressures, it has become mandatory for almost all industrial sectors to comply with environmental regulations and treat the effluents, if any. There are about 285 distilleries in India generating effluents, of which nearly 177 have either implemented or are on the verge of completing effluent treatment plants. The effluents from distillery units are treated with a dual purpose of pollution abatement and recovery of energy. Indian Renewable Energy Development Agency Ltd. (IREDA) has so far funded 59 process industries, mostly distillery units, for the generation of biogas from effluents. IREDA's contribution towards the generation of biogas by financing these units amounts to about 0.86 million cubic meters of biogas per day which is equivalent to saving 965 tonnes of coal per day, in turn leading to carbon dioxide avoidance of about 1,330 tonnes per day. IREDA conducted a sample study on performance of these biogas plants and their impact on environment

    This paper addresses the phenotypic variation among Ricinus communis L. populations in four urban habitat types (road verges, garbage dumps, construction debris, and natural area) in Delhi, India, by evaluating important traits such as plant height, basal circumference, seeds per plant, seed size, seed weight, specific leaf area, and reproductive index. An important biochemical marker, proline, considered as a good plant performance indicator under stress was also quantified in leaves of R. communis to evaluate its response in different habitats. Interestingly, the species showed significant variation in plant height, specific leaf area, seed size, seed weight, and leaf proline content in different habitat types. Leaf proline content was positively related to plant height, specific leaf area, and seed size while negatively related to the total number of seeds/plant. Interestingly, reproductive index, calculated as a ratio of the total number of seeds to the plant height also showed a negative relation with leaf proline content. Results indicated that R. communis exhibits adaptive modulation of growth, reproductive traits, and leaf proline content in various urban habitats which contributes to invasiveness, range expansion, and establishment of the species. The study also gives evidence of how morphological and physiological traits could directly affect invasiveness of R. communis.

  16. Rumors of Our Demise Have Been Greatly Exaggerated: Archaeological Perspectives on Culture and Sustainability

    Full Text Available Predictions of the imminent demise of Indigenous cultures have circulated among Western intellectuals for more than two hundred years. Capitalism, Christianity, and Western civilization were thought by 19th century scholars to be on the verge of eradicating global cultural variation. Contemporary scholars have revived these views, suggesting that not only were Indigenous cultures about to succumb to Western hegemony, these forces were poised to bring about the end of history itself. What unites these perspectives are an ideology stressing asymmetrical power relations between the West and Indigenous cultures, and the proposition that only Western intervention is capable of rescuing Indigeneity. This paper examines the current crisis of Indigenous cultural sustainability, arguing that the epistemology informing many of these perspectives remain largely unchanged from their 19th century precursors. Citing case studies in archaeology and cultural heritage management, I suggest a ground-up approach to cultural sustainability in which Western institutions and individuals serve only the expressed desires and at the invitation of Indigenous peoples. Such restraint represents both recognition of Indigenous sovereignty regarding all cultural preservation efforts, as well as the dynamic, ever-changing nature of culture itself.

  17. On the Origin of Metadata

    Full Text Available Metadata has been around and has evolved for centuries, albeit not recognized as such. Medieval manuscripts typically had illuminations at the start of each chapter, being both a kind of signature for the author writing the script and a pictorial chapter anchor for the illiterates at the time. Nowadays, there is so much fragmented information on the Internet that users sometimes fail to distinguish the real facts from some bended truth, let alone being able to interconnect different facts. Here, the metadata can both act as noise-reductors for detailed recommendations to the end-users, as it can be the catalyst to interconnect related information. Over time, metadata thus not only has had different modes of information, but furthermore, metadata’s relation of information to meaning, i.e., “semantics”, evolved. Darwin’s evolutionary propositions, from “species have an unlimited reproductive capacity”, over “natural selection”, to “the cooperation of mutations leads to adaptation to the environment” show remarkable parallels to both metadata’s different modes of information and to its relation of information to meaning over time. In this paper, we will show that the evolution of the use of (metadata can be mapped to Darwin’s nine evolutionary propositions. As mankind and its behavior are products of an evolutionary process, the evolutionary process of metadata with its different modes of information is on the verge of a new-semantic-era.

    A 22-year-old female presented with multiple painless bilateral breast masses for the past 2 months. On Further questioning she had hematochezia and constipation for three months. On digital rectal examination, thickening of rectal mucosa at 5 cm from the anal verge was found. On physical examination, multiple firm, non-tender, nodular lesions were found in bilateral breasts. Metastatic breast disease from extra mammary primaries is uncommon and it constitutes 0.5 - 6% of all breast malignancies. melanomas, lymphomas, leukemias, ands sarcomas are the most common malignancies causing breast metastases. Infrequently, carcinomas of the lung, stomach, ovary, liver, tonsil, pleura, pancreas, cervix, perineum, endometrium, bladder, carcinoid tumors and renal cell carcinomas can cause metastatic breast disease. Metastatic breast disease from colorectal cancer is characterised by disseminated metastatic disease and a poor prognosis. In this case, It was essential to distinguish between metastatic breast disease primary breast carcinoma to plan appropriate management. Because of its rare incidence and high index of clinical suspicion, appropriate radiological investigations and histopathology is essential for accurate diagnosis. {sup 18}F-FDG PET/CT, being a whole-body metabolic functional imaging modality, helped us determine the extent of the primary and metastatic disease. In view of disseminated metastases, the bilateral breast disease was also considered as metastatic involvement, Which was proven by histopathology.

  19. Women's employment and changing gender relations in Puerto Rico.

    2010-01-01

    This article discusses Helen Safa's analyses of the impact of development strategies and social policies on gender relations and women headed families in the Caribbean and Puerto Rico. The discussion focuses on findings of a research project regarding patterns of women's employment, autonomy, marital relations, family headship and poverty in Puerto Rico in the decade beginning in the year 2000, using excerpts from interviews conducted with women workers displaced from a clothing and a tuna factory between 2001 and 2002 (Colón et al. 2008), as well as data from the Public Use Sample (PUMS) of the U.S. Census Puerto Rico Community Survey 2005-2007. It is argued that women's employment has resulted in advances in women's autonomy, gender equity, and renegotiations of the provider role, but, intensified by men's unstable earnings, it has also led to the increase of female family headship even among married women. Women's education and employment have been an important means of reducing family poverty both among dual earner families and female heads. Yet, the continuing joblessness in the Island places even higher educated sectors on the verge of economic precariousness.

  20. Future Visions of the Brahmaputra - Establishing Hydrologic Baseline and Water Resources Context

    The Brahmaputra River Basin (China-India-Bhutan-Bangladesh) is on the verge of a transition from a largely free flowing and highly variable river to a basin of rapid investment and infrastructure development. This work demonstrates a knowledge platform for the basin that compiles available data, and develops hydrologic and water resources system models of the basin. A Variable Infiltration Capacity (VIC) model of the Brahmaputra basin supplies hydrologic information of major tributaries to a water resources system model, which routes runoff generated via the VIC model through water infrastructure, and accounts for water withdrawals for agriculture, hydropower generation, municipal demand, return flows and others human activities. The system model also simulates agricultural production and the economic value of water in its various uses, including municipal, agricultural, and hydropower. Furthermore, the modeling framework incorporates plausible climate change scenarios based on the latest projections of changes to contributing glaciers (upstream), as well as changes to monsoon behavior (downstream). Water resources projects proposed in the Brahmaputra basin are evaluated based on their distribution of benefits and costs in the absence of well-defined water entitlements, and relative to a complex regional water-energy-food nexus. Results of this project will provide a basis for water sharing negotiation among the four countries and inform trans-national water-energy policy making.

  1. Central and Eastern Europe After the Boom - Time for a Stragegy Change for Foreign Multinationals?

    2013-06-01

    Full Text Available In 2008 the global financial and economic crisis ended a six-year-long boom period with an average growth rate well above 5% in Central and Eastern Europe (CEE. Although not the originators of the crisis some CEE countries such as the Baltic States and Ukraine were among the worst hit by this economic downturn. The crisis did not only shatter the financial markets, banks and the real economy but also the growth image of CEE. The huge market potential and expected higher growth rates resulting from the catching-up process to West European standards have been the main reason for the flood of foreign direct investments into the countries of the region in the two decades before. Suddenly, foreign direct investors were confronted with stalled and even collapsing market growth, shrinking disposable household income, business customers and partners on the verge of bankruptcy and no real sign of a quick recovery. While the situation improved a little in 2011, the economic outlook and the sentiment of foreign investors have remained gloomy, at least for parts of the region. It is obvious that when faced with such a huge economic downturn companies stop geographic expansion and put the brakes on investments.

    The world is on the verge of achieving global polio eradication. During >25 years of operations, the Global Polio Eradication Initiative (GPEI) has mobilized and trained millions of volunteers, social mobilizers, and health workers; accessed households untouched by other health initiatives; mapped and brought health interventions to chronically neglected and underserved communities; and established a standardized, real-time global surveillance and response capacity. It is important to document the lessons learned from polio eradication, especially because it is one of the largest ever global health initiatives. The health community has an obligation to ensure that these lessons and the knowledge generated are shared and contribute to real, sustained changes in our approach to global health. We have summarized what we believe are 10 leading lessons learned from the polio eradication initiative. We have the opportunity and obligation to build a better future by applying the lessons learned from GPEI and its infrastructure and unique functions to other global health priorities and initiatives. In so doing, we can extend the global public good gained by ending for all time one of the world's most devastating diseases by also ensuring that these investments provide public health dividends and benefits for years to come.

  4. Nuclear Renaissance? Think Globally, Act Locally

    International Nuclear Information System (INIS)

    Lawrence, Michael J.

    2001-01-01

    There is wide-scale belief in the nuclear industry that we are on the verge of a revival of nuclear power because of the projected large increase in the demand for non-carbon emitting electrical generating capacity. Energy consumption will at least double over the next 50 years as a result of population increase and the very real need to improve the standard of living particularly in developing countries. Growing acceptance of the need to reduce carbon emissions is positioning nuclear energy as a likely candidate to meet this increased demand provided valid concerns about economics, safety, proliferation and waste can be adequately resolved. While economics, safety, and proliferation resistance all can benefit from incremental improvement, a permanent waste disposal solution either exists or it doesn't. If a country cannot identify where it will dispose of its spent fuel or high-level nuclear waste, its further use of nuclear energy can be blocked. A number of countries today have generated significant quantities of spent fuel or high-level waste without firm plans or suitable geology for disposal of this material

    Current helioseismology observations allow the determination of the frequencies and surface velocity amplitudes of solar acoustic modes with exceptionally high precision. In some cases, the frequency accuracy is better than one part in a million. We show that there is a distinct possibility that quadrupole acoustic modes of low order could be excited by gravitational waves (GWs), if the GWs have a strain amplitude in the range 10{sup –20} h {sub –20} with h {sub –20} ∼ 1 or h {sub –20} ∼ 10{sup 3}, as predicted by several types of GW sources, such as galactic ultracompact binaries or extreme mass ratio inspirals and coalescence of black holes. If the damping rate at low order is 10{sup –3}η {sub N} μHz, with η {sub N} ∼ 10{sup –3}-1, as inferred from the theory of stellar pulsations, then GW radiation will lead to a maximum rms surface velocity amplitude of quadrupole modes of the order of h{sub −20}η{sub N}{sup −1}∼ 10{sup –9}-10{sup –3} cm s{sup –1}, on the verge of what is currently detectable via helioseismology. The frequency and sensitivity range probed by helioseismological acoustic modes overlap with, and complement, the capabilities of eLISA for the brightest resolved ultracompact galactic binaries.

    Composite Higgs Models are often constructed including fermionic top partners with a mass around the TeV scale, with the top partners playing the role of stabilizing the Higgs potential and enforcing partial compositeness for the top quark. A class of models of this kind can be formulated in terms of fermionic strongly coupled gauge theories. A common feature they all share is the presence of specific additional scalar resonances, namely two neutral singlets and a colored octet, described by a simple effective Lagrangian. We study the phenomenology of these scalars, both in a model independent and model dependent way, including the bounds from all the available searches in the relevant channels with di-boson and di-top final states. We develop a generic framework which can be used to constrain any model containing pseudo-scalar singlets or octets. Using it, we find that such signatures provide strong bounds on the compositeness scale complementary to the traditional EWPT and Higgs couplings deviations. In many cases a relatively light scalar can be on the verge of discovery as a first sign of new physics.

    Fuel cell technologies for stationary power are set to play a role in power generation applications worldwide. The worldwide fuel cell vision is to provide powerplants for the emerging distributed generation and on-site markets. Progress towards commercialization has occurred in all fuel cell development areas. Around 100 ONSI phosphoric acid fuel cell (PAFC) units have been sold, with significant foreign sales in Europe and Japan. Fuji has apparently overcome its PAFC decay problems. Industry-driven molten carbonate fuel cell (MCFC) programs in Japan and the U.S. are conducting megawatt (MW)-class demonstrations, which are bringing the MCFC to the verge of commercialization. Westinghouse Electric, the acknowledged world leader in tubular solid oxide fuel cell (SOFC) technology, continues to set performance records and has completed construction of a 4-MW/year manufacturing facility in the U.S. Fuel cells have also taken a major step forward with the conceptual development of ultra-high efficiency fuel cell/gas turbine plants. Many SOFC developers in Japan, Europe, and North America continue to make significant advances.

    While the islands of Sao Tome e Principe (STP) were once a leading cocoa producer, cocoa production is now relatively insignificant and the country is little known today outside the lusophone world. But STP could soon gain strategic and economic importance as its territorial waters are suspected to hold large quantities of crude oil. This article explores STP's shift away from domination by cocoa exports, narrating the decline and final collapse of the plantation economy and the country's slide towards overwhelming dependence on external assistance in the form of foreign aid and external debt. In this context, it calls STP an unviable state as its fledgling domestic economy fails to generate enough revenue to sustain its highly import-reliant consumption patterns. But it finds STP on the verge of another major transformation as it is likely to become a crude oil producer within a few years. In the course of this research, the authors came across major irregularities in the conduct of the country's oil policy and some of this information appears for the first time in the public domain. In this context, their research points to opportunities for rent-seeking and corrupt behaviour, which stem from access to foreign aid and natural resources. (author)

    World Health Assembly (WHA) in 1988 encouraged the member states to launch Global Polio Eradication Initiative (GPEI) (resolution WHA41.28) against "the Crippler" called poliovirus, through strong routine immunization program and intensified surveillance systems. Since its launch, global incidence of poliomyelitis has been reduced by more than 99 % and the disease squeezed to only three endemic countries (Afghanistan, Pakistan, and Nigeria) out of 125. Today, poliomyelitis is on the verge of eradication, and their etiological agents, the three poliovirus serotypes, are on the brink of extinction from the natural environment. The last case of poliomyelitis due to wild type 2 strain occurred in 1999 in Uttar Pradesh, India whereas the last paralytic case due to wild poliovirus type 3 (WPV3) was seen in November, 2012 in Yobe, Nigeria. Despite this progress, undetected circulation cannot fully rule out the eradication as most of the poliovirus infections are entirely subclinical; hence sophisticated environmental surveillance is needed to ensure the complete eradication of virus. Moreover, the vaccine virus in under-immunized communities can sometimes revert and attain wild type characteristics posing a big challenge to the program.

    Degradable magnesium alloys for biomedical application are on the verge of being used clinically. Rare earth elements (REEs) are used to improve the mechanical properties of the alloys, but in more or less undefined mixtures. For some elements of this group, data on toxicity and influence on cells are sparse. Therefore in this study the in vitro cytotoxicity of the elements yttrium (Y), neodymium (Nd), dysprosium (Dy), praseodymium (Pr), gadolinium (Gd), lanthanum (La), cerium (Ce), europium (Eu), lithium (Li) and zirconium (Zr) was evaluated by incubation with the chlorides (10-2000 microM); magnesium (Mg) and calcium (Ca) were tested at higher concentrations (200 and 50mM, respectively). The influence on viability of human osteosarcoma cell line MG63, human umbilical cord perivascular (HUCPV) cells and mouse macrophages (RAW 264.7) was determined, as well as the induction of apoptosis and the expression of inflammatory factors (TNF-alpha, IL-1alpha). Significant differences between the applied cells could be observed. RAW exhibited the highest and HUCPV the lowest sensitivity. La and Ce showed the highest cytotoxicity of the analysed elements. Of the elements with high solubility in magnesium alloys, Gd and Dy seem to be more suitable than Y. The focus of magnesium alloy development for biomedical applications should include most defined alloy compositions with well-known tissue-specific and systemic effects.

    The purpose of the study was to identify the accuracy of high-resolution MRI in the pre-operative assessment of mesorectal fascia involvement, circumfrential resection margin (CRM) and local staging in patients with rectal carcinoma. The study included 56 patients: 32 male and 24 female. All patients underwent high-resolution MRI and had confirmed histopathological diagnosis of rectal cancer located within 15 cm from the anal verge, followed by surgery. MRI findings were compared with pathological and surgical results. The overall accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of MRI-based T-staging were 92.8, 88.8%, 96.5%, 96%, and 90.3%, respectively. The accuracy, sensitivity, specificity, PPV, and NPV of MRI-based assessment of CRM were 94.6%, 84.6%, 97.6%, 91.4, and 94.6%, respectively. The accuracy, sensitivity, specificity, PPV, and NPV of MRI-based N-staging were 82.1%, 75%, 67.3%, 60%, and 86.1%, respectively. Preoperative high-resolution rectal MRI is accurate in predicting tumor stage and CRM involvement. MRI is a precise diagnostic tool to select patients who may benefit from neo-adjuvant therapy and to avoid overtreatment in those patients who can proceed directly to surgery

  14. A thermodynamic approach to obtain materials properties for engineering applications

    1993-01-01

    With the ever increases in the capabilities of computers for numerical computations, we are on the verge of using these tools to model manufacturing processes for improving the efficiency of these processes as well as the quality of the products. One such process is casting for the production of metals. However, in order to model metal casting processes in a meaningful way it is essential to have the basic properties of these materials in their molten state, solid state as well as in the mixed state of solid and liquid. Some of the properties needed may be considered as intrinsic such as the density, heat capacity or enthalpy of freezing of a pure metal, while others are not. For instance, the enthalpy of solidification of an alloy is not a defined thermodynamic quantity. Its value depends on the micro-segregation of the phases during the course of solidification. The objective of the present study is to present a thermodynamic approach to obtain some of the intrinsic properties and combining thermodynamics with kinetic models to estimate such quantities as the enthalpy of solidification of an alloy.

    We present facsimiles of some of the scientifically and historically most relevant papers published in Astronomische Nachrichten/Astronomical Notes (AN) between 1821 and 1938. Almost all of these papers were written and printed in German and it is sometimes not completely straightforward to find these original works and then to cite the historically correct version, e.g. in case of a series of articles or editorial letters. It was common during the early years that many contributions were made in form of letters to the editor. We present a summary for these original works with an English translation of their titles. Among the highlights are the originals of the discovery of stellar parallaxes by Friedrich Wilhelm Bessel, the discovery of the solar cycle by Heinrich Schwabe, the discovery of the planet Neptune by Johann Gottfried Galle, the first ever measured stellar radial velocity by Hermann Vogel, the discovery of radio emission from the Sun by Wilsing and Scheiner, the first ever conducted photoelectric photometry of stars by Paul Guthnick and up to the pioneering work by Karl Schwarzschild, Ejnar Hertzsprung, Erwin Finlay Freundlich and others. As a particular gimmick we present the still world record holding shortest paper ever published; by Johannes Hartmann in AN 226, 63 (1926) on Nova Pictoris. Our focus is on contributions in the early years and published until 1938 near the verge of the second world war.

    Next-generation sequencing (NGS), an innovative sequencing technology that enables the successful analysis of numerous gene sequences in a massive parallel sequencing approach, has revolutionized the field of molecular biology. Although NGS was introduced in a rather recent past, the technology has already demonstrated its potential and effectiveness in many research projects, and is now on the verge of being introduced into the diagnostic setting of routine laboratories to delineate the molecular basis of genetic disease in undiagnosed patient samples. We tested a benchtop device on retrospective genomic DNA (gDNA) samples of controls and patients with a clinical suspicion of a mitochondrial DNA disorder. This Ion Torrent Personal Genome Machine platform is a high-throughput sequencer with a fast turnaround time and reasonable running costs. We challenged the chemistry and technology with the analysis and processing of a mutational spectrum composed of samples with single-nucleotide substitutions, indels (insertions and deletions) and large single or multiple deletions, occasionally in heteroplasmy. The output data were compared with previously obtained conventional dideoxy sequencing results and the mitochondrial revised Cambridge Reference Sequence (rCRS). We were able to identify the majority of all nucleotide alterations, but three false-negative results were also encountered in the data set. At the same time, the poor performance of the PGM instrument in regions associated with homopolymeric stretches generated many false-positive miscalls demanding additional manual curation of the data.

  17. Political challenges for China at the beginning of the 21st century

    Full Text Available The Chinese economic model, which paved the way to «Chinese economic miracle» is running out of its capabilities. The new generation of leadership led by Xi Jinping is facing an extremely complicated task that can be compared to the one Deng Xiaoping had solved at the turn of 1980’s – to elaborate a new model of development. Measures adopted by the new General secretary of the CPC Central Committee in order to concentrate powers and to strengthen personal power are justifi ed by the need to change political course. However, as a result of these steps, the system of institutional authoritarianism that for the past 40 years was being created and provided economic success to China has been signifi cantly demolished. Current challenges for China originate not only from the necessity to change the economic model, but also from the reaction of the authorities to this need. Amidst uncertainty of new reference points for the reforms, lack of obvious competitive advantages, strengthening of external challenges and deep changes in Chinese society, China has again appeared on the verge of serious challenges, the answer to which will help evaluate the effectiveness of the reforms not only from socio-economic but also from a historical perspective.

    Full Text Available Este artículo plantea que una separación conyugal puede significar para las mujeres una oportunidad para recobrar su libertad, su autoestima y empoderarse; también aborda tanto lo relativo a la dinámica de discriminación y murmuraciones que la falta de una pareja corresidente suele desencadenar en propios y extraños en contra de esas mujeres, como las maneras negativas en que ellas propenden a percibirse a sí mismas y a su familia. Con base en entrevistas en profundidad semiestructuradas, la construcción y el análisis de relatos de vida de treinta y un mujeres divorciadas, se llega a la conclusión que el divorcio es una suerte de transgresión a las estructuras sociales de género que, en el corto plazo, provoca en sus protagonistas femeninas vergüenza de su condición y auto-segregación pero que, en el largo o mediano plazo, les puede abrir posibili- dades a la reinvención de sí como mujeres liberadas y empoderadas.

  19. Optical coherence tomography assessment and quantification of intracoronary thrombus: Status and perspectives

    Coronary angiography is the “golden standard” imaging technique in interventional cardiology and it is still widely used to guide interventions. A major drawback of this technique, however, is that it is inaccurate in the evaluation and quantification of intracoronary thrombus burden, a critical prognosticator and predictor of intraprocedural complications in acute coronary syndromes. The introduction of optical coherence tomography (OCT) holds the promise of overcoming this important limitation, as near-infrared light is uniquely sensitive to hemoglobin, the pigment of red blood cells trapped in the thrombus. This narrative review will focus on the use of OCT for the assessment, evaluation and quantification of intracoronary thrombosis. - Highlights: • Thrombotic burden in acute coronary syndromes Is not adequately evaluated by standard coronary angiography, whereas Optical Coherence Tomography is exquisitely sensitive to the hemoglobin contained in red blood cells and can be used to precisely quantify thrombus. • Both research and clinical applications have been developed using the OCT-based evaluation of thrombus. In particular, whereas precise quantification scores are useful for comparing antithrombotic therapies in randomized trials, both pharmacological and mechanical, the most important practical applications for OCT-based assessment of thrombus are the individuation of culprit lesions in the context of diffuse atheromata in acute coronary syndromes, and the so-called “delayed stenting” strategies. • Improvements in 3D rendering techniques are on the verge of revolutionizing OCT-based thrombus assessment, allowing extremely precise quantification of the thrombotic burden

  20. Force and torque of a string on a pulley

    de Oliveira, Thiago R.; Lemos, Nivaldo A.

    2018-04-01

    Every university introductory physics course considers the problem of Atwood's machine taking into account the mass of the pulley. In the usual treatment, the tensions at the two ends of the string are offhandedly taken to act on the pulley and be responsible for its rotation. However, such a free-body diagram of the forces on the pulley is not a priori justified, inducing students to construct wrong hypotheses such as that the string transfers its tension to the pulley or that some symmetry is in operation. We reexamine this problem by integrating the contact forces between each element of the string and the pulley and show that although the pulley does behave as if the tensions were acting on its ends, this comes only as the final result of a detailed analysis. We also address the question of how much friction is needed to prevent the string from slipping over the pulley. Finally, we deal with the case in which the string is on the verge of sliding and show that this cannot happen unless certain conditions are met by the coefficient of static friction and the masses involved.

    2015-01-01

    At the beginning of WWI, the Canadian astronomical community was tiny and astrophysical research was just beginning. By the end of the war, the country had established the forerunner of its National Research Council and had the world's largest fully operational telescope, thanks to the late entry of the USA into the conflict. By 1918, Canada was on the verge of making significant contributions to science.In spite of the immense loss of life in this pointless war, I am aware of only one casualty affecting Canadian professional astronomers, and that was the indirect death of James Chant, son of University of Toronto's only professor of astronomy. Other Canadian astronomers, including Tom Parker, Bert Topham, and Harry Plaskett were on active service; each of their stories is unique.Among those engaged in scientific work during the war were two Canadians temporarily in England: John McLennan whose helium research for dirigibles led him to establish a cryogenic lab in Toronto where the green line in the spectrum of the aurora was identified in 1925, and Allie Douglas who worked as a statistician in the War Office. Later work with Eddington led her to become his biographer and to her distinction as the first person in Canada to earn a PhD in astronomy (in 1926).

    During World War I, social and health conditions were difficult in Brod na Savi, as it stationed a large number of troops, and the military hospital was crowded with patients. With so many able-bodied men and breadwinners mobilised, the town's economy verged on the brink of poverty, but people managed to keep starvation at bay. The most common diseases among civilians were tuberculosis, malaria, intestinal infectious diseases, diphtheria, and venereal diseases, and in 1915 cholera broke out that lasted five months. At the end of 1918 "Spanish flu" also hit the town. The number of wounded and sick soldiers occasionally surpassed the hospital's capacity, so they had to be stationed at the local school facilities for a while. Over two thousand people died in the military hospital, which suggests that the total number of patients who went through the hospital had to be very large. Unfortunately, there are no records to show the hospital's mortality rate or disease prevalence. We are currently trying to establish the demographics of the 2000 dead buried at the local cemetery during WWI using the death records we have.

  5. 1950s Athens as Palimpsest: A BBC Radio Play by Louis MacNeice

    2015-11-01

    Full Text Available Louis MacNeice’s Portrait of Athens, a radio play broadcast by the BBC in November 1951, came at a time of reconstruction throughout Europe but also at a time when the world was on the verge of yet another war. In it we find the city’s bones, Athens of Thucydides, Demosthenes, Pericles and Socrates, but also a modern city where you could hear street cries, radio tunes and trams and visit both Kolonaki and the district of New Smyrna where Asia Minor refugees had settled almost thirty years earlier. Twenty-four centuries were transposed to twenty-four hours and twenty-four hours squeezed into the space of one with the play focusing on questions of memory, identity, and lived or remembered traumas. What the audience got as a result was a representation of the varied layers that made up modern Athens, a portrait of the city as palimpsest in contrast to other accounts of the same period where the past dominated over the present making the latter non visible.

  6. Entanglement and optimal quantum information processing

    Today we are standing on the verge of new enigmatic era of quantum technologies. In spite of the significant progress that has been achieved over the last three decades in experimental generation and manipulation as well as in theoretical description of evolution of single quantum systems, there are many open problems in understanding the behavior and properties of complex multiparticle quantum systems. In this thesis, we investigate theoretically a number of problems related to the description of entanglement - the nonlocal feature of complex quantum systems - of multiparticle states of finite-dimensional quantum systems. We also consider the optimal ways of manipulation of such systems. The focus is made, especially, on such optimal quantum transformations that provide a desired operation independently on the initial state of the given system. The first part of this thesis, in particular, is devoted to the detailed analysis of evolution of entanglement of complex quantum systems subjected to general non-unitary dynamics. In the second part of the thesis we construct several optimal state independent transformations, analyze their properties and suggest their applications in quantum communication and quantum computing.

  7. Jewish disappearing acts and the construction of gender.

    Johnston, Ruth D

    2006-01-01

    In this essay I propose to investigate the interarticulation of race/ethnicity and gender at two fin de siècle moments: the conceptualization of the Oedipus complex at the turn of the twentieth century and the conceptualization of gender as performative in contemporary queer theory. Though these gender constructions contrast strikingly with one another-queer theory opposes and calls into question the heteronormativity of the Oedipal itinerary-both theories are produced through the displacement of racial/ethnic difference onto sexual and gender difference. One line of investigation in this essay is to relate their difference to the distinct situations of ethnic in-betweenness in which they were produced. Freud's situation as a Jew undergoing assimilation to Western European customs has been compared to that of the post-colonial subject. Judith Butler's and Eve Kosofsky Sedgwick's theories of queer performativity have been located in a post-assimilationist situation in the U.S. of the 1990s. At both moments a doubling takes place but with a radical shift in perspective. Whereas the post-colonial subject undergoes a psychic splitting in which the point of view of the colonizer predominates and promotes assimilation via mimicry, the post-assimilation subject performatively constructs difference, often by a reverse mimicry that involves identification with a subaltern group. Finally, in both situations the notion of "queer incoherence" is deployed not to negate gay and lesbian specificity, but rather to articulate such specificity as historically emergent, on the verge of definition.

    During the year a final paper was produced on XI* production from 2.9 GeV/c K - p interactions, and a paper on the Σ - π - π + (π 0 ) final state from 2.9 GeV/c K - d interactions is on the verge of completion. From our 14.75 GeV/c anti pp experiment results have been prepared for publication on three topics: the charm search, V 0 inclusive production, and π 0 production. Further analysis of data is continuing. In the 300 GeV/c pp experiment, investigations are completed or underway in three areas: neutral and charged pion correlations, inclusive γ and V 0 production, and inclusive resonance production. Further data on inclusive V 0 distributions from 6.5 GeV/c K - p interactions has been obtained and analysis is nearing completion. A good deal of effort went into the development of proposals for new physics. These new directions may be represented by three approved experiments at three different laboratories: Neutrino-deuterium interactions at Fermilab (an approved and a proposed experiment); Search for new states decaying into anti ΛΛ and K 0 /sub s/K 0 /sub s/ using the Multiparticle Spectrometer at B.N.L. (approved in May, 1977); Search for baryonium using the SLAC hybrid bubble chamber system, which won approval in September with a recommendation for prompt running from the Program Advisory Committee.

  10. A Historical Legacy Untouched by Time and Space? The Hollowing-out of the Norwegian Model of Industrial Relations

    Ann Cecilie Bergene

    2016-03-01

    Full Text Available The Norwegian model of industrial relations has received a lot of praise. It is generally thought of as the pinnacle of the welfare state, a reason why Norway is not severely hit by crises, is highly adaptable, and thus still going strong. This article discusses the historical circumstances in which the model arose with a view to analyze the preconditions for its further existence, arguing that the model must be understood as consisting of, and thus dependent upon, shifting historical subjects. This calls for an analysis of the concrete interactions between various agents, and how it has changed over time and space. In this effort, historical accounts are combined with theories developed within the social sciences in order to explain the dynamics of these interactions. We will argue that the contemporary notion of a Norwegian model of industrial relations, and the accompanying praise, is an ahistorical conceptualization verging on a dogma, and that profound reconfigurations of power relations between the agents of labor and capital need to be taken into account.

    Full Text Available Las caricias y la sexualidad nos ayudan a soportar mejor el estrés, pero por otro lado la sexualidad causa estrés cuando existe un conflicto en este campo. ¿Y quién no tiene ningún conflicto en este campo? Pueden haber miedos irracionales de la sexualidad porque la clasificamos inconscientemente como algo malo, algo prohibido. Después de una experiencia sabrosa podemos tener emociones de vergüenza o de culpabilidad: una rica fuente de estrés. Si queremos establecer normas humanas razonables para el campo erótico-sexual, será necesario renunciar a prejuicios religiosos basados en la ignorancia y atizados por el deseo de tener poder de “defensores de la fe” equivocados. Si no, sería mas adecuado que en el campo sexual rija el mismo humanismo que en otras regiones sociales, o sea: No es aceptable que se exploten los mas débiles o dependientes, no es aceptable poner en peligro la salud mental o física de otra persona (por ejemplo ocultando una enfermedad venérea. Y, sólo es aceptable si la pareja consiente.

  12. Functions of Expressions of Futurality in Professional Economic Texts

    2016-07-01

    Full Text Available The aim of this corpus-based study is to identify the functions that selected expressions of futurality can express in professional economic texts. The classification of functions is established on the corpus of seven economic books. Excerpted instances of futural constructions are analysed with respect to textual and interpersonal functions as defined by Halliday. Futurality is interpreted broadly to include all lexical and grammatical means referring to the future. This approach makes it also possible to analyse futurality as a means of text coherence. Hence the core grammatical means are interpreted along with co-occurring lexical means under the two categories of functions to provide a comprehensive model of text coherence with regard to futurality. Frequency analysis shows that core futural expressions are not distributed equally throughout the corpus. While some expressions (e.g., will and the present simple tense dominate, others prove to be rather insignificant (e.g., be on the point/verge of, the present progressive tense. In addition, both lexical and grammatical constructions regularly co-occur in clusters, contributing to the coherence of the economic texts.

    Fasola, E.; Ribeiro, R.; Lopes, I.

    2015-01-01

    The loss of genetic diversity, due to exposure to chemical contamination (genetic erosion), is a major threat to population viability. Genetic erosion is the loss of genetic variation: the loss of alleles determining the value of a specific trait or set of traits. Almost a third of the known amphibian species is considered to be endangered and a decrease of genetic variability can push them to the verge of extinction. This review indicates that loss of genetic variation due to chemical contamination has effects on: 1) fitness, 2) environmental plasticity, 3) co-tolerance mechanisms, 4) trade-off mechanisms, and 5) tolerance to pathogens in amphibian populations. - Highlights: • Effects of environmental stressors on the genetic diversity of natural populations of amphibians have usually been underestimated. • Environmental pollution may reduce the genetic diversity of exposed amphibian populations. • Genetic erosion can lead to reduced fitness and lack of adaptability to a changing environment. - Contaminant-driven genetic erosion is a major threat to population viability in amphibians

    Full Text Available India is home to a multitude of art forms. The rich cultural diversity of India lies at the very root of its existence. However, many of these art forms have either completely vanished into the unknown or are on the verge of extinction. This paper provides a brief account of one such art forms called, Aipan, a Kumaoni folk art practised in the North Indian state of Uttarakhand. This is discussed in the backdrop of ‘Project Aipan’, initiated by the Enactus team of Indraprastha College for Women, University of Delhi. Consisting of rhythmic geometrical patterns made of lines and dots, Aipan is traditionally made on Geru (an earthy-red surface with white rice paste. It is practiced on special ceremonies and household rituals to evoke divine blessings. Project Aipan worked towards strengthening communities, bound by a common thread of hope fostered by collective entrepreneurial actions. Through this paper, an attempt is made to highlight the struggle to keep alive the Aipan art form and sustaining it for posterity. The role of women in this struggle is also highlighted, be it the Kumaoni women who have been the practitioners of this art form, or the women team of Enactus IPCW who took the charge of protecting this heritage.

Owing to their exceptional natural integrity, national park is the treasure of great national importance. Villages (hamlets are integral parts of national park, but are sadly on the verge of disappearing, due to lack of inhabitants. The locals that choose to stay, by fighting for their village's survival and existence, are coming into a conflict with the management board of the national park (mainly directed towards the protection and preservation of biodiversity resources. The research presented here focused on Jagoštica village, located in the far northwestern part of Tara National Park, Serbia. According to the landscape reading, mapped land­scape (spatial elements and social survey, the researched aim was the development of a unique model for sustainable development, focused at protecting diversity of flora and fauna, as well as improving the living standards of local people. Rural tourism and production of local traditional products were found to be the most optimal strategies for moderating the development of this area.

  16. Unbundling the corporation.

    Science.gov (United States)

    Hagel, J; Singer, M

    1999-01-01

    No matter how monolithic they may seem, most companies are really engaged in three kinds of businesses. One business attracts customers. Another develops products. The third oversees operations. Although organizationally intertwined, these businesses have conflicting characteristics. It takes a big investment to find and develop a relationship with a customer, so profitability hinges on achieving economies of scope. But speed, not scope, drives the economics of product innovation. And the high fixed costs of capital-intensive infrastructure businesses require economies of scale. Scope, speed, and scale can't be optimized simultaneously, so trade-offs have to be made when the three businesses are bundled into one corporation. Historically, they have been bundled because the interaction costs--the friction--incurred by separating them were too high. But we are on the verge of a worldwide reduction in interaction costs, the authors contend, as electronic networks drive down the costs of communicating and of exchanging data. Activities that companies have always believed were central to their businesses will suddenly be offered by new, specialized competitors that won't have to make trade-offs. Ultimately, the authors predict, traditional businesses will unbundle and then rebundle into large infrastructure and customer-relationship businesses and small, nimble product innovation companies. And executives in many industries will be forced to ask the most basic question about their companies: What business are we really in? Their answer will determine their fate in an increasingly frictionless economy.

    ENGLISH ABSTRACT: Operations Research is perceived to be on the verge of demise as a decision support tool in industry. However, this is not true, since the relevancy and interdisciplinary nature of Operations Research makes it an indispensable part of operations management. What should rather be asked is how Operations Research is introduced to undergraduate industrial engineering students. This paper reports on one of the optimisation initiatives undertaken for a service contractor using integer programming as part of a semester project. Although the model addresses specific business issues related to the contractor, it can easily be generalised for other applications.

    1994-01-01

    The frontiers in Physics are dominated by the contributors of Abdus Salam in terms of new basic ideas. These contributions have their most fascinating synthesis in the following question: does the Superworld exist? The only possible answer to this question is to review the most basic results of Super-Grand unification. We focus the attention on two specific models and their predictions. These two models represent an example of a direct comparison between a traditional unified-theory and a string-inspired approach to the solution of the many open problems of the Standard Model. Viable models must satisfy all available experimental constraints and be as simple as theoretically possible. The two well defined supergravity models, SU(5) and SU(5) x U(1), can be described in terms of only a few parameters (five and three respectively) instead of the more than twenty needed in the MSSM model, i.e., the Minimal Supersymmetric extension of the Standard Model. A case of special interest is the strict no-scale SU(5) x U(1) supergravity where all predictions depend on only one parameter (plus the top-quark mass). A general consequence of these analyses is that the Superworld can be at the verge of discovery, lurking around the corner at present and near future facilities. This is in fact the projection of Salam's dream in the real axis. (author). 45 refs, 10 figs, 1 tab

    1998-01-06

    With the advent of the new extragalactic deuterium observations, Big Bang nucleosynthesis (BBN) is on the verge of undergoing a transformation. In the past, the emphasis has been on demonstrating the concordance of the BBN model with the abundances of the light isotopes extrapolated back to their primordial values by using stellar and galactic evolution theories. As a direct measure of primordial deuterium is converged upon, the nature of the field will shift to using the much more precise primordial D/H to constrain the more flexible stellar and galactic evolution models (although the question of potential systematic error in 4He abundance determinations remains open). The remarkable success of the theory to date in establishing the concordance has led to the very robust conclusion of BBN regarding the baryon density. This robustness remains even through major model variations such as an assumed first-order quark-hadron phase transition. The BBN constraints on the cosmological baryon density are reviewed and demonstrate that the bulk of the baryons are dark and also that the bulk of the matter in the universe is nonbaryonic. Comparison of baryonic density arguments from Lyman-alpha clouds, x-ray gas in clusters, and the microwave anisotropy are made.

  20. THE “EASTERN PARTNERSHIP” PROJECT: DOES POLAND’S VOICE STILL MATTER?

    2016-10-01

    Full Text Available When in the year 2009 Radoslaw Sikorski and Carl Bildt, architects of the Eastern Partnership project, launched the ambitious scheme of bringing the six post-Soviet countries closer to the EU, they could hardly predict that in nearly five years the tremendous diplomatic, political efforts to design an effective soft power approach would find itself on the verge of failure. In this relation, Poland’s role in bringing the EaP countries under the umbrella of the project long before becoming the EU member, however, most productively since joining the organization, could not be underestimated. Despite a complicated historical legacy with some of the EaP members, namely, Ukraine, Belarus and Moldova, Poland together with the Baltic countries turned out to be a vocal proponent of bringing the former ones under the initiative, aiming to empower them with the leverage against Russia’s successful efforts to destabilize the region and preserve domination in its immediate neighbourhood. Nevertheless, taking into account the changes in Poland’s political climate, namely, victory of the Law and Justice Party in both presidential and parliamentary elections of 2015 as well as its pessimist stance towards effectiveness of the Eastern Partnership project, the question arises whether Poland’s voice still matters in the future of the EaP and whether it sees itself as the moving force of the project.

  1. [The myth of the good savage].

    The conquest of the New World gave way to the myth of the Good Savage. For the Renaissance intellectuals, the ancient ideas about the Golden Age (an ideal society promising an unending bliss) seemed to be brought back to life at last. Sharply contrasting with the European exacerbated unrest of the time, America stood for a redeeming hope, a symbol of a better future. The myth of the Good Savage assumes people to be naturally good, but civilization has led them into the realm of violence, hatred, and cruelty. Besides being naturally good, nice-minded people, "good savages" were also useful, obedient people, most likely to be easily exploited by Europeans--a source for the historical drama to come. On the verge of freeing itself from the Spanish rule, Latin America--fighting its way toward independence, had three enlightened mentors: Voltaire, Rousseau, and Montesquieu. There, again, another deep contrast arose between the abstract characteristics of Latin American aims to perfection, and people's actual behaviors. The former "good savage" became the modern "Latin American" embodying an utopia as well as a hope in his eagerness for setting up a plural, and humanized culture. The myth of the Good Savage represents a deep longing for an objectivation of the ego-ideal: it has been used, so to speak, in collective mobilizations as well as dogmatic crystallizations, to escape from ignominous realities or to project alternatives for a better socially-shared life.

    Full Text Available This article presents a syntactic analysis and comparison of diminutive suffixes in Russian, Kolyma Yukaghir, and Itelmen, three genetically unrelated languages of the Russian Federation. Kolyma Yukaghir and Itelmen are on the verge of extinction. This article investigates how contact with Russian (specifically the syntax of Russian diminutives has influenced the syntax of diminutives in Kolyma Yukaghir and Itlemen. Adopting the framework of Distributed Morphology, a syntactic analysis of diminutives across the three languages reveals that they share the same manner of syntactic attachment, but differ in regards to the site or place of attachment. Specifically, it is proposed that diminutives in all three languages are syntactic modifiers; however, in relation to the place of attachment, in Russian, diminutives attach below the functional category of Number, while diminutives in Kolyma Yukaghir and Itelmen attach above the Number category. This article contributes to our understanding of variation in universal grammar and linguistic outcomes of the syntactic feature ‘diminutive’ in a multilingual situation where a majority language is in contact with two genetically unrelated endangered languages.

  3. Burnout Syndrome: Global Medicine Volunteering as a Possible Treatment Strategy.

    2018-04-01

    In the last few decades, "burnout syndrome" has become more common among clinicians, or at least more frequently recognized. Methods to prevent and treat burnout have had inconsistent results. Simultaneously, clinicians' interest in global medicine has increased dramatically, offering a possible intervention strategy for burnout while providing help to underserved areas. Caused by a variety of stressors, burnout syndrome ultimately results in physicians feeling that their work no longer embodies why they entered the medical field. This attitude harms clinicians, their patients and colleagues, and society. Few consistently successful interventions exist. At the same time, clinicians' interest in global medicine has risen exponentially. This paper reviews the basics of both phenomena and posits that global medicine experiences, although greatly assisting target populations, also may offer a strategy for combating burnout by reconnecting physicians with their love of the profession. Because studies have shown that regular volunteering improves mental health, short-term global medicine experiences may reinvigorate and reengage clinicians on the verge of, or suffering from, persistent burnout syndrome. Fortuitously, this intervention often will greatly benefit medically underserved populations. Copyright © 2018 Elsevier Inc. All rights reserved.

  4. Electric vehicles: The role and importance of standards in an emerging market

    2010-01-01

    After nearly a century with the internal combustion engine dominating the personal transportation sector, it now appears that the electric vehicle is on the verge of experiencing rapid growth in both developed and developing vehicle markets. The broad-scale adoption of the electric vehicle could bring significant changes for society in terms of not only the technologies we use for personal transportation, but also moving our economies away from petroleum and lessoning the environmental footprint of transportation. This article investigates the role of standards, related training and certification for the electric vehicle. It is argued that the potential for the electric vehicle will be stunted without adequate attention being paid to standards, not only in terms of the speed of its uptake and smoothness of this transition, but also in terms of maintaining compatibility between jurisdictions, safety of the public, and helping to ensure environmental sustainability. We highlight a number of areas where new or adaptations of current standards, training and certification may be needed, notably in terms of batteries and charging infrastructures, electricity distribution and accounting for the environmental characteristics of this electricity, and different aspects of vehicle-to-grid and smart grid technologies.

Y en la medida en que lo lograba, la biografía, como género invertido entre lo ficcional y lo factual, debió ser desterrada para que así la Historia, que debía escribirse con H mayúscula, alcanzara la ansiada respetabilidad científica. Dado su carácter inclasificable e impuro, por su cercanía a lo literario, a lo intuitivo, a lo emotivo o a cualquier tipo de subjetivismo, la biografía terminó por ser recluida al cuarto de las cosas viejas, allá atrás donde no hiciera pasar vergüenza a nadie, junto a las trompetas y los tambores de la historia de los grandes héroes.

    Predation is known to impact growth and reproduction, and the physiological state of the prey, including its susceptibility to oxidative stress. In this study, we investigated how prolonged exposure to predators modulates tissue specific antioxidant defense and oxidative damage in the short-lived epibenthic scallop Argopecten ventricosus (2years maximum lifespan). Scallops that were experimentally exposed to predators had not only lower antioxidant capacities (superoxide dismutase and catalase), but also lower oxidative damage (protein carbonyls and TBARS=thiobarbituric acid reactive substances including lipid peroxides) in gills and mantle compared to individuals not exposed to predators. In contrast, oxidative damage in the swimming muscle was higher in predator-exposed scallops. When predator-exposed scallops were on the verge of spawning, levels of oxidative damage increased in gills and mantle in spite of a parallel increase in antioxidant defense in both tissues. Levels of oxidative damage increased also in the swimming muscle whereas muscle antioxidant capacities decreased. Interestingly, post-spawned scallops restored antioxidant capacities and oxidative damage to immature levels, suggesting they can recover from spawning-related oxidative stress. Our results show that predator exposure and gametogenesis modulate oxidative damage in a tissue specific manner and that high antioxidant capacities do not necessarily coincide with low oxidative damage.

    To determine the hospital autopsy rate for the UK in 2013. A study of data from a 'Freedom of Information' request to all (n=186) acute NHS Trusts within England (n=160), NHS Boards in Scotland (n=14) and Wales (n=7) and Social Care Trusts in Northern Ireland (n=5). Hospital autopsy rates were calculated from the number of hospital autopsies performed in 2013 as a percentage of total inpatient deaths in the Trust that year. The UK response rate was 99% (n=184), yielding a mean autopsy rate of 0.69%. The mean rates were 0.51% (England), 2.13% (Scotland), 0.65% (Wales) and 0.46% (Northern Ireland). 23% (n=38) of all included respondents had a rate of 0% and 86% (n=143) a rate less than 1%. The decline in hospital autopsy has continued relentlessly and, for better or for worse, the practice is on the verge of extinction in the UK. The study highlights to health professionals and policy makers the magnitude of this decline. Further research should investigate the impact of this on patient safety, clinical audit, public health and medical education. Published by the BMJ Publishing Group Limited.

  9. In mortal hands. A cautionary history of the nuclear age

    2011-01-01

    This provocative history of nuclear power is perfectly timed. Americans are gravely concerned with nuclear terrorism even as a nuclear renaissance is seen as a possible solution to global warming. Few have truly come to terms with the complexities of an issue that may determine the future of the planet. It was once hoped nuclear weapons would bring wars to an end. Instead they spurred a massive arms race that has recently expanded to include North Korea and Iran. Once seen as a source of unlimited electricity, nuclear reactors breed contamination and have been used as covers for secret weapons programs from India and Pakistan to Iraq and Iran. The evolving story of nuclear power, as told by industry insider Stephanie Cooke, reveals the gradual deepening of our understanding of the pros and cons of this controversial energy source. Drawing on her unprecedented access, Cooke shows us how, time and again, the stewards of the nuclear age - the more-is-better military commanders and civilian nuclear boosters - have fallen into the traps of their own hubris and wishful thinking as they tried to manage the unmanageable. Their mistakes are on the verge of being repeated again, which is why this book deserves especially close attention.

  10. The history of wealth concept and ways to achieve it for sustainable development

    Full Text Available The evolution of well-known philosophers and economists views on wealth is considered: Voltaire, Adam Smith, JeanJacques Rousseau, Karl Marx, John Stuart Mill, Milton Friedman, John Maynard Keynes, Joseph Schumpeter, Georg von Wallwitz and others. Economics was initially studying ways and means of achieving wealth. The essence of wealth has changed dramatically in people's minds after the first and the second industrial revolutions. The world today is on the verge of the third industrial revolution (according to Jeremy Rifkin, or, as it is called by many scientists, the new tenor of technology. In the history of any civilization comes the moment of a radical direction change for new prospects or endangered. Not all civilizations were able to transform in time. However, in the past, the effects of civilizations collapse were limited in time, space, and never addressed the species. Currently, the high probability of temperature and planet geochemistry changes as a result of climate change can lead to mass extinction of animals, plants, and people. Humanity has the ability to transit into a stable post-carbon era in the middle of the century and to prevent catastrophic climate change. Currently, sustainable development is the mechanism used to achieve the ultimate goal of any country, enterprise and human development, which is wealth. Under controlled sustainable development we understand the system unity of not only economic, social, environmental, but also resource, technological, institutional activities, as well as a permanent interaction between development and economic safety.

  11. Scientific Psychology in the 18th Century: A Historical Rediscovery.

    2016-05-01

    As early as 1783, the almost forgotten philosopher, metaphysicist, and psychologist Ferdinand Ueberwasser (1752-1812) designated himself "Professor für empirische Psychologie und Logik" (professor of empirical psychology and logic) at the University of Münster, Germany. His position was initiated and supported by the minister and educational reformer Franz von Fürstenberg (1729-1810), who considered psychology a core scientific discipline that should be taught at each school and university. At the end of the 18th century, then, psychology seems to have been on the verge of becoming an independent academic discipline, about 100 years before Wilhelm Wundt founded the discipline's first official laboratory. It seems surprising that Ueberwasser's writings-including a seminal textbook on empirical psychology-have been almost entirely overlooked in most historical accounts. We focus on this important founding moment of psychological science and on the circumstances that eventually brought this seminal development to a halt. © The Author(s) 2016.

    Photonic quantum technologies are on the verge of finding applications in everyday life with quantum cryptography and quantum simulators on the horizon. Extensive research has been carried out to identify suitable quantum emitters and single epitaxial quantum dots have emerged as near-optimal sources of bright, on-demand, highly indistinguishable single photons and entangled photon-pairs. In order to build up quantum networks, it is essential to interface remote quantum emitters. However, this is still an outstanding challenge, as the quantum states of dissimilar "artificial atoms" have to be prepared on-demand with high fidelity and the generated photons have to be made indistinguishable in all possible degrees of freedom. Here, we overcome this major obstacle and show an unprecedented two-photon interference (visibility of 51 ± 5%) from remote strain-tunable GaAs quantum dots emitting on-demand photon-pairs. We achieve this result by exploiting for the first time the full potential of a novel phonon-assisted two-photon excitation scheme, which allows for the generation of highly indistinguishable (visibility of 71 ± 9%) entangled photon-pairs (fidelity of 90 ± 2%), enables push-button biexciton state preparation (fidelity of 80 ± 2%) and outperforms conventional resonant two-photon excitation schemes in terms of robustness against environmental decoherence. Our results mark an important milestone for the practical realization of quantum repeaters and complex multiphoton entanglement experiments involving dissimilar artificial atoms.

    The properties of exotic nuclei on the verge of existence play a fundamental part in our understanding of nuclear interactions. Exceedingly neutron-rich nuclei become sensitive to new aspects of nuclear forces. Calcium, with its doubly magic isotopes $^{40}$Ca and $^{48}$Ca, is an ideal test for nuclear shell evolution, from the valley of stability to the limits of existence. With a closed proton shell, the calcium isotopes mark the frontier for calculations with three-nucleon forces from chiral effective field theory. Whereas predictions for the masses of $^{51}$Ca and $^{52}$Ca have been validated by direct measurements$^4$, it is an open question as to how nuclear masses evolve for heavier calcium isotopes. Here we report the mass determination of the exotic calcium isotopes $^{53}$Ca and $^{54}$Ca, using the multi-reflection time-of-flight mass spectrometer of ISOLTRAP at CERN. The measured masses unambiguously establish a prominent shell closure at neutron number N = 32, in excellent agreement with our t...

    Full Text Available El objetivo de este trabajo es recuperar las ideas de Norbert Elías que dan pistas para la comprensión de los mecanismos de soportabilidad social y los dispositivos de regulación de las sensaciones que se hacen carne y hueso en los procesos de producción y reproducción social, particularmente delimitados en el contexto de América Latina. Para ello, en primer lugar, se explicitan las nociones de proceso y figuraciones. En un segundo momento, se examinan las principales transformaciones en el mundo subjetivo a partir de la vergüenza y el desagrado. Luego se analiza la noción del 'romanticismo', para terminar con una serie de reflexiones sobre los aportes de Elías para una sociología de los cuerpos y las emociones, que se proponga estar en una alerta epistémica desde una mirada latinoamericana poscolonial.

  17. The future of small telescopes in the new millennium

    The motivation for these volumes is to provide a vision for the future of small telescopes. While this is an admirable task, ultimately I believe that­ as happens all the time in science - the prognostications will be overtaken by a rapidly changing scientific reality. As Virginia Trimble points out in chapter 1, the kinds of big questions that face us as astronomers today are rather different than the ones that drove the construction of astronomical facilities through much of the twentieth century. Right now, it appears that small telescopes will not have a lot of influence in answering those questions, though they will of course contribute enormously to the many issues discussed throughout the three volumes. Weare on the verge of opening a whole new parameter space that may revolutionize the way we think of small telescopes and their role in astronomy - the domain of the rapidly variable sky. While the LSST is the most prominent example, it is a long way in the future. Nemiroff & Rafert (chapter 2) con...

Although worldwide strong efforts have been made to implement human milk (HM donation, there is currently little available research on donors characteristics and their influence on volume and composition of DHM. The present study aimed to evaluate the relationship between social-demographic variables of donating mothers (age, residence, job, number of children, as well as gestational age and birth weight of their babies, and volume and composition of donated HM.The analysis of data revealed a statistically significant impact of maternal age and profession, as well as babies’ birth weight and donation duration, on the volume of milk donation, but no effect of donor’s place of residence. Gestational age also had an effect on the volume of milk donation, but the effect was not statistically significant (p-value on the verge of significance.Regarding milk composition, gestational age < 29 weeks, low birth weight and overall donation period were statistically correlated to higher protein content. Statistical analysis of other DHM components did not result significant except for carbohydrates, being their content inversely associated with birth weight, with p-value at the margin of significance.

    [Purpose] The objective of this study was to determine the effect of indoor horseback riding and virtual reality exercises on the dynamic balance ability of normal adults. [Subjects] This study enrolled 24 normal adults and divided them into two groups: an indoor horseback riding exercise group (IHREG, n = 12) and a virtual reality exercise group (VREG, n = 12). [Methods] IHREG exercised on indoor horseback riding equipment and VREG exercised using the Nintendo Wii Fit three times a week for six weeks. The Biodex Balance System was used to analyze dynamic balance as measured by the overall stability index (OSI), anteroposterior stability index (APSI), and mediolateral stability index (MLSI). [Results] In the within-group comparison, IHREG and VERG both showed significant decreases in the dynamic balance indexes of OSI, APSI, and MLSI after the intervention, but no significant difference was found between the groups. [Conclusion] Both indoor horseback riding and virtual reality exercises were effective at improving the subjects’ dynamic balance ability as measured by OSI, APSI, and MLSI, and can be used as additional exercises for patients with conditions affecting postural control.
