    In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification difficult due to genotypic similarity. Even so, the most likely mother could be identified unambiguously among offspring in most of the clutches studied. Two non-parental females displayed maternal behavior which would have misled managers in assigning maternity based on behavior alone. This set of variable loci demonstrates the utility of parentage testing in captive propagation programs. PMID:21637468

    Exposure to environmental contaminants known as endocrine disruptors (EDs) alters the development and function of reproductive organs in several species. Bisphenol A (BPA) is an estrogenic chemical that leaches from dental materials and plastic food and beverage containers. BPA has been found in sewage, surface and drinking water, and therefore poses a potentially significant risk for human and wildlife. Prenatal exposure of rodents to environmentally relevant doses of BPA alters the development of the reproductive organs of male and female offspring. Species with temperature dependent sex determination (TSD) could act as sentinels of ecosystem health by providing sensitive biomarkers of endocrine disruptor's effects. We selected Caiman latirostris as an animal model to study endocrine disruption caused by BPA. The aim of this study was to determine whether exposure in ovum to BPA could cause estrogen-like effects on the reproductive system of C. latirostris. Sex determination and gonadal histoarchitecture were the endpoints evaluated after in ovum exposure to different doses of BPA and 17beta-estradiol (E(2)). We confirmed that C. latirostris is a species with TSD and additionally demonstrated that BPA causes estrogen-like developmental effects by reversing gonadal sex and altering gonadal histoarchitecture. Differences in responses to BPA and E(2) in our in vivo system were on the order of 100-fold. In contrast published in vitro studies have reported differences on the order of 10,000x or more. These results support the utility of C. latirostris, a species in which sex determination is temperature dependent, as a tool in assessing estrogenic activity in vivo and as a sentinel to monitor EDs in aquatic environment.

    The aim of this study was to establish normal ophthalmic parameters for selected diagnostic tests, and to describe the orbital anatomy and adnexal histology of the broad-snouted caiman. A total of 35 Caiman latirostris that were free of obvious ocular diseases were used to measure the parameters in this investigation. Ages ranged from 5 to 15 years. Ophthalmic diagnostic tests were conducted, including evaluation of tear production with Schirmer Tear test-1 (STT1), culture of the conjunctival bacterial flora, applanation tonometry, conjunctival cytology, nictiating membrane incursion frequency test (NMIFT), endodontic absorbent paper point tear test (EAPPTT), palpebral fissure length measurement (PFL) and B-mode ultrasonography. Adnexal histology and skull samples were studied. Mean (±SD) STT1 was 3.4 ± 3.6 mm/min (95% confidence interval of 2.01-4.78 mm/min), intraocular pressure (IOP) was 12.9 ± 6.2 mmHg, NMIFT was 6.0 ± 3.5, EAPPTT was 17.1 ± 2.5 mm/min, PFL was 28.9 ± 3.0 mm, anterior chamber depth was 3.1 ± 0.3 mm, lens axial length was 8.4 ± 0.6 mm, vitreous chamber depth was 7.9 ± 0.7 mm and axial globe length was 19.9 ± 1.3 mm.

    Full Text Available Populations of Caiman latirostris are known to occur in Uruguay but their geographic distribution remains uncertain. This work presents anupdate of the species distribution and conservation status in Uruguay. Surveys conducted by the authors confirmed the presence of this species in the previously known distribution range of northwestern Uruguay, where it seems to be widespread and relatively abundant in contrast to earlier reports. We report new localities for C. latirostris, most relevant being those of the Cebollatí and Tacuarí Rivers, and the Pelotas, India Muerta and San Miguel stream basins, which significantly expand its distribution through important wetlands in the eastern part of the country. The overall distribution is coincident with different landscape types, where lagoons, artificial impoundments, livestock waterholes, rivers, streams, creeks and marshes are inhabited by caiman. Illegal non-commercial hunting was detected all over the country.

Sixteen seven-month old caimans, average weight of 208 g and, 38 cm of total lenght (TL were distributed in four treatments. Four groups of four caimans each were placed in cement enclosures inside a greenhouse. Diets were supplied at the average rate of 97.8% ± 34.8% of the body weight per week (average and standard deviation; wet weight basis. Body mass and total length of caimans were measured every 30 days for six months (Nov. 1995-April. 1996. An analysis of variance with repeated measures was performed. Diets provided suitable growth for weight and TL (mean ± standard deviation, respectively: (a 2,157 ± 743 g and 79.5 ± 6.9 cm; (b 1,811 ± 222 g and 75.7 ± 1.9 cm; (c 2,431 ± 780 g and 80.7 ± 5.8 cm; (d 1,683.5 ± 736 g and 74.5 ± 7.2 cm. There was no significant effect of diet on weight, but diet effect on TL of hatchlings approached significance (p < 0.10. It is concluded that all diets have good potential, in growth sense, to be used in commercial farms or ranches and for captivity propagation programs of caimans.

    Using histological and histochemical methods for glicoconjugates, the present work on the salivary glands of the alligator Caiman latirostris (Crocodilia Reptilia, was developed. On the bases of the results obtained, the authors believe that those glands are not well developed, appearing as unicellular structures goblet-like cells, in the stratified squamous epithelium of the oral cavity. Scattered glands alveolus without excretory tubules which extend directly with the epitelium were also present. By means of histochemical methods for glicoconjugates, it was possible to detect the glicoprotein and the sialic acid in the glandular formation of these animals.

    Empregando-se métodos histológicos e histoquímicos para glicoconjugados, desenvolveu-se um trabalho sobre glândulas salivares do jacaré Caiman latirostris. Com base nos resultados obtidos, constatou-se que estas glândulas são pouco desenvolvidas, aparecendo como estruturas unicelulares, semelhantes às células caliciformes, incluídas no epitélio estratificado pavimentoso da cavidade oral. Observou-se, ainda, a presença de esparsos alvéolos glandulares desprovidos de ductos excretores que continuam diretamente com o epitélio. Por meio de métodos histoquímicos para glicoconjugados, foi possível a detecção de glicoproteína e de ácido siálico nas formações glandulares desses animais.

    Full Text Available Thirty heads with the neck segment of Caiman latirostris were used. The animals were provided from a creation center called Mister Caiman, under the authorization of the Brazilian Institute of Environment and Renewable Natural Resources (Ibama. Animals were sacrificed according to the slaughtering routine of the abattoir, and the heads were sectioned at the level of the third cervical vertebra. The arterial system was washed with cold saline solution, with drainage through jugular veins. Subsequently, the system was filled with red colored latex injection. Pieces were than fixed in 20% formaldehyde, for seven days. The brains were removed, with a spinal cord segment, the duramater removed and the arteries dissected. At the level of the hypophysis, the internal carotid artery gave off a rostral branch, and a short caudal branch, continuing, naturally, as the caudal cerebral artery. This artery projected laterodorsalwards and, as it overpassed the optic tract, gave off its I (the first central branch. Penetrated in the cerebral transverse fissure, emitting the diencephalic artery and next its II (second central branch. Still inside the fissure, originated occipital hemispheric branches and a pineal branch. Emerged from the cerebral transverse fissure, over the occipital pole of the cerebral hemisphere. Projected rostralwards, sagital to the cerebral longitudinal fissure, as interhemispheric artery. This artery gave off medial and convex hemispheric branches to the respective surfaces of the cerebral hemispheres, anastomosed with its contralateral homologous, forming the common ethmoidal artery. This artery entered the fissure between the olfactory peduncles, emerging ventrally and dividing into ethmoidal arteries, right and left, which progressed towards the nasal cavities, vascularizing them. The territory of the caudal cerebral artery included the most caudal area of the base of the cerebral hemisphere, its convex surface, the olfactory

    Agricultural activities associated mainly with soybean crops affect the natural environment and wildlife by habitat destruction and the extensive use of agrochemicals. The aim of this study was to evaluate immunotoxic effects of the insecticides cypermethrin (CYP) and endosulfan (END) in Caiman latirostris analyzing total blood cell count (TWBC) and differential white blood cell count (DWBC) after in ovo and in vivo exposure. Eggs (in ovo) and hatchlings (in vivo) from nests harvested in natural habitats were artificially incubated and reared under controlled conditions in the Proyecto Yacaré (Gob.Santa Fe/MUPCN) facilities. Exposure of embryos was performed by topication on the eggshell during the first stage of development. The treatments were distilled water (negative control; NC), ethanol (vehicle control; VC), four groups treated with different concentrations of CYP and four groups with END. In vivo exposure was performed by immersion; treatments were NC, VC, two groups exposed to CYP and two to END. After embryonic exposure to the insecticides, no differences were found in TWBC or DWBC among the neonates exposed to pesticides versus controls. In the in vivo scenario, similar results were obtained for TWBC, but DWBC data showed differences between NC hatchlings and CYP-1 hosts for heterophil, lymphocyte and monocyte levels, and between NC and END-1 hosts for lymphocyte and monocyte levels. Research on the effects of pesticide exposure on this species is of special interest not only to assess the impact on caiman populations, but also to further characterize the species as a potential sentinel of ecosystem health.

  12. Abundance and local range of broad-snouted caiman (Caiman latirostris, Alligatoridae in the northwest of Santa Catarina Island

    Full Text Available This is the first report on the distribution and relative abundance of the broad-snouted caiman on Santa Catarina Island. The study estimated the relative abundance of caiman along the rivers at Estação Ecológica de Carijós, in addition to evaluating the occurrence of this species in the entire area of the Ratones River plain on the northwestern portion of the island. The mean relative abundance obtained by nocturnal counts was 0.25 (±0.07 caiman/km surveyed. There was a weak correlation between the number of caimans and the air temperature. Based on interviews with the local community and nocturnal surveys of caimans in rivers and reservoirs surrounding the protected area, we concluded that the range occupied by caimans covered the entire area of the Ratones river plain, inhabiting natural habitats (rivers, mangroves, swamps as well as artificial habitats (reservoirs and water channels. Although this study provides basic information about the broad-snouted caiman population on this part of the island, it is aimed mainly at providing guidance for future research.

  13. Temperature- vs. estrogen-induced sex determination in Caiman latirostris embryos: Both females, but with different expression patterns of key molecules involved in ovarian development.

    Caiman latirostris is a species with temperature dependent sex determination (TSD), which implies that the incubation temperature of the eggs is the main factor that determines the sex during a thermo-sensitive period (TSP). However, estrogens play a critical role in this process. The administration of 17β-estradiol (E 2 ) previous to TSP overrides the effects of male incubation temperature, producing phenotypic females. This effect has been defined as sex reversal or estrogen-induced sex determination (E 2 SD). The aim of the present study is to describe similarities and differences in the effects of TSD and E 2 SD treatment conditions on ovary development. Our results show that the two treatment conditions studied are able to produce different ovaries. Treatment with E 2 modified the expression pattern of estrogen receptor alpha and progesterone receptor, and expression of the enzyme aromatase. Moreover, in E 2 SD females, the proliferation/apoptosis dynamic was also altered and high expression of TAp63 was observed suggesting the presence of greater DNA damage in germ cells. To the best of our knowledge, this is the first report that describes the morphology of the female gonad of C. latirostris in three stages of embryonic development and shows the expression of TAp63 during the gonad development of a reptile. It is important to emphasize that the changes demonstrated in E 2 SD female gonads of embryos show that environmental compounds with proven estrogenic activity alter the follicular dynamics of C. latirostris in neonatal as much as in juvenile animals, endangering their reproductive health and possibly bringing consequences to ecology and evolution.

    Caiman latirostris is a reptilian species that exhibits temperature-dependent sex determination (TSD). Male-to-female sex reversal can be achieved after in ovo estrogen/xenoestrogen exposure. This is known as hormone-dependent sex determination (HSD). The amh, sox9 and sf-1 genes are involved in sex determination, sex differentiation, and steroidogenesis. The aims of this study were: (a) to establish the expression patterns of amh, sox9 and sf-1 mRNA in the gonad-adrenal-mesonephros (GAM) complexes of neonatal TSD-male and TSD-female caimans, (b) to compare the expression of these genes between TSD-females and HSD-females (born from E2-exposed eggs incubated at the male-producing temperature) and (c) to evaluate whether in ovo exposure to a low dose of E2 or bisphenol A (BPA) or to a high dose of endosulfan (END) modifies amh, sox9 or sf-1 mRNA expressions in neonatal males. The mRNA expressions of amh, sox9 and sf-1 in GAM complexes from TSD-males and TSD-females and from HSD-females were quantitatively compared by RT-PCR. A sexually dimorphic pattern of amh and sox9 mRNA expression was found, with a higher expression in TSD-males than in TSD-females. sf-1 mRNA did not differ between TSD-males and TSD-females. HSD-females exhibited a higher expression of sox9 than TSD-females. In males, increased mRNA expression of sex-determining genes was observed after in ovo exposure to END. E2 decreased sox9 but increased sf-1 mRNA expression. Changes induced by BPA were evident although not significant. These results provide new insights into the potential mechanisms that lead to the gonadal histo-functional alterations observed in caimans exposed to contaminated environments.

Como resultado, ambas especies fueron categorizadas como No Amenazadas, en base a información actualizada sobre sus áreas de distribución y su abundancia. Los criterios aplicados para el desarrollo de los programas de manejo de ambas especies en Argentina han permitido ampliar el conocimiento de las mismas en una gran diversidad de aspectos. El aprovechamiento sostenible de los yacarés mediante la metodología de cría en granjas o "rancheo" ha demostrado ser de bajo impacto para las poblaciones silvestres y ha revalorizado los humedales que estos reptiles habitan. After more than a decade from the first Red List of the Herpetofauna of Argentina assessed in 2000, we reclassified the two species of argentine caimans, starting from actual information about their biology, biogeography and ecology and including methodological adjustments. As a result, both species Caiman latirostris and C. yacare were included in the Not Endangered category, based on new records about their geographic distribution and populations densities. The criteria applied to the development of management programs of crocodilians in Argentina has improved the knowledge of both species and made a great and wide contribution to several aspects of their biology. The sustainable use of both species of crocodilians has proved to have a minimum impact on wild populations and has put a new value on the wetlands inhabited by this reptiles.

    Spectacled caiman (Caiman crocodilus) are fish-eating crocodilians that inhabit freshwater habitat in tropical regions of the Americas. To assess the exposure of caiman to pesticides from banana plantations, the authors collected whole blood samples (30 mL) from 14 adult caiman that were captured in the North Atlantic region of Costa Rica. Blood samples were analyzed for 70 legacy- and current-use pesticides and breakdown products using newly developed ultra-trace, high-resolution mass spectrometry (HRMS). Caiman accumulated pesticides ranked by concentration as dieldrin > permethrin > mirex > 4,4'-DDE > alpha-endosulfan > heptachlor epoxide > oxychlordane > heptachlor > cypermethrin. Caiman within the high-intensity banana crop watershed of Rio Suerte had higher pesticide burdens relative to other more remote locations (F = 12.79; p = 0.00). Pesticide concentration decreased with distance from upstream banana plantations in this river system (F = 20.76; p = 0.00). Caiman body condition was negatively correlated with total pesticide concentrations (F = 6.23; p = 0.02) and with proximity to banana plantations (F = 5.05; p = 0.04). This suggests that either pesticides elicited toxic effects in caiman, resulting in diminished overall health, or that the quantity or quality of their prey was reduced by pesticides downstream of plantation waterways. The authors' results indicate that pesticide use in banana plantations is impacting a high trophic level species inhabiting one of the most important wilderness areas in Costa Rica (Tortuguero National Park). © 2013 SETAC.

    The Paraguayan caiman (Caiman yacare) is the main Caimaninae species occurring in the Brazilian Pantanal Wetland. Despite the relative availability of works focused on biology and conservation of the Paraguayan caiman, almost nothing is known about its vocal structure and behavior. We recorded aggressive calls of adult caiman females guarding nests and, afterwards, the distress calls of the new born juvenile caimans in seasonally flooded areas of the Nhecolândia (Southern Pantanal). The results of both observations and sonographic analyses diverged from studies with other crocodilian species. Aggressive vocalization of adult females of the Paraguayan caiman was longer and more complex than the same vocalization of larger Alligatoridae species. Vocalizations of the young caimans presented interspecific differences with other crocodilian offsprings. Moreover, we found statistically significant intraspecific variation in the distress call structure among different pods, even separated by few kilometers. Differences in distress call structure were tested by Canonical Discriminant Analysis (CDA). We obtained the squared Mahalanobis distances between the acoustic multivariate spaces of each pod provided by the CDA and compared with the geographic distance between the bays of origin of each pod through Mantel Test. The geographic distance by itself did not explain the differences found in the structure of the vocalization of young caimans from different pods. The adult females of Paraguayan caiman positively responded to playbacks of calls from juvenile caimans from pods of other regions, as well as to rough imitations of distress call. Since the adult caimans showed protective responses to quite heterogeneous vocalizations of distress by juveniles, we hypothesized that the variation in the distress call pattern may be associated to a low specificity in sound recognition by adult caimans.

    Classification and influence matrix analysis (CAIMAN) is a new classification method, recently proposed and based on the influence matrix (also called leverage matrix). Depending on the purposes of the classification analysis, CAIMAN can be used in three outlines: (1) D-CAIMAN is a discriminant classification method, (2) M-CAIMAN is a class modelling method allowing a sample to be classified, not classified at all, or assigned to more than one class (confused) and (3) A-CAIMAN deals with the asymmetric case, where only a reference class needs to be modelled. In this work, the geographic classification of samples of wine and olive oil has been carried out by means of CAIMAN and its results compared with discriminant analysis, by focusing great attention on the model predictive capabilities. The geographic characterization has been carried out on three different datasets: extra virgin olive oils produced in a small area, with a "protected denomination of origin" label, wines with different denominations of origin, but produced in enclosed geographical areas, and olive oils belonging to different production areas. Final results seem to indicate that the application of CAIMAN to the geographical origin identification offers several advantages: first, it shows--on an average basis--good performances; second, it is able to deal in a simple way classification problems related to tipicity, authenticity, and uniqueness characterization, which are of increasing interest in food quality issues.

    The spectacled caiman (Caiman crocodilus) was introduced to Puerto Rico over 50 years ago with the Tortuguero Lagoon Natural Reserve (TLNR) as its epicenter, where it is now established as an apex predator. Although concerns have been raised regarding the potential impact of this naturalized predator on Puerto Rico’s native fauna, little was known of the caiman’s diet...

    Full Text Available On the Amazon floodplain, the main predators of black caiman (Melanosuchus niger eggs are jaguars (Panthera onca, tegu lizards (Tupinambis teguixim, capuchin monkeys (Sapajus macrocephalus and humans (Homo sapiens. In this study, we investigated the relationship between predator attacks on nests and incubation period, and evaluated the influence of initial predation on subsequent predation in the Mamirauá Sustainable Development Reserve. We also evaluated the influence of presence of females near the nests and manipulation of nests on the occurrence of attacks. We compared results from data obtained with camera traps and vestiges left by predators on estimates of rates of predation by different predators. Egg predation was recorded in 32% of the 658 black caiman nests monitored during two years. Our results suggest that the probability of predation on black caiman eggs is relatively constant throughout the incubation period and that predation on eggs was lower when adults, presumably females, were present. Careful opening of nests and handling of eggs did not increase the number of attacks on black caiman nests. Nest opening by a predator appeared to increase the chances of a subsequent attack because most of the attacks on nests occurred soon after a predator first opened the nest. However, attacks by another species of predator do not appear to be necessary to initiate attacks by any other species of predator. Results based on camera traps and vestiges differed, but use of vestiges was adequate for identifying the principal predators on eggs in black caiman nests and, in many circumstances, the vestiges may be better for estimating predation by humans. In this study, opening nests and handling eggs did not increase the number of attacks on black caiman nests.

    Growth of the Orinoco Caiman (Crocodylus intermedius, Crocodylia: Crocodylidae) under two captivity conditions. In order to determine the growth of Caiman of the Orinoco (Crocodylus intermedius) under two conditions of captivity, 40 specimens were raised during 11 months and 15 days in two circular tanks, with 28.3 m2 of surface area and a volume of 62.2 m3 in each tank. The tanks were built with concrete walls and guarded blocks covered internally with sheets of myrrhlike resin, and a roof of galvanized sheets. One tank was covered partially with the galvanized sheets (tank I), the other was totally covered (tank II). Twenty caimans were placed in each tank, and both groups were fed with 85% beef, 10% fresh fish, 5% hen eggs and a mixture of minerals and vitamins. The length and weight differed significantly between the groups (p tank II, (tank I: 88.9 +/- 7.58 cm; 2 705 +/- 0.69 g). The greater growth in tank II reflects higher air and water temperatures. The survival rate was 97.5%. These results can be used for rearing caimans in captivity for conservation and commercial purposes.

    Full Text Available The sporogony of Hepatozoon caimani has been studied, by light microscopy, in the mosquito Culex fatigans fed on specimens of the caiman Caiman c. crocodilus showing gametocytes in their peripheral blood. Sporonts iniciate development in the space between the epithelium of the insect gut and the elastic membrane covering the haemocoele surface of the stomach. Sporulating oocysts are clustered on the gut, still invested by the gut surface membrane. Fully mature oocysts were first seen 21 days after the blood-meal. No sporogonic stages were found in some unidentified leeches fed on an infected caiman, up to 30 days following the blood-meal. When mosquitoes containing mature oocysts were fed to frogs (Leptodactylus fuscus and Rana catesbeiana, cysts containing cystozoites developed in the internal organs, principally the liver. Feeding these frogs to farm-bred caimans resulted in the appearance of gametocytes in their peripheral blood at some time between 59 and 79 days later, and the development of tissue cysts in the liver, spleen, lungs and kidneys. Transmission of the parasite was also obtained by feeding young caimans with infected mosquitoes and it is suggested that both methods occur in nature. The finding of similar cysts containing cystozoites in the semi-aquatic lizard Neusticurus bicarinatus, experimentally fed with infected C. fatigans, suggests that other secondary hosts may be involved.

    Full Text Available ABSTRACT: This study evaluated the yield, color, and chemical composition of commercial cuts (tail, sirloin cut, back fillet, and thigh of Pantanal caiman meat in both sexes. The yield of tail was higher than other cuts, and the yield of females (17.0% was higher than males (15.9%. The thigh of males had lower protein content (20.8% compared with other cuts. Females showed a higher lipid content in the tail (2.4% and thigh (0.8% compared with males (1.7% and 0.4%, respectively. The tail presented the greatest content of monounsaturated fatty acids (45.2% and higher n6/n3 ratio (4.6. Although lightness was not different among cuts or between sexes, there were differences in color. Males have more yellowish meat compared with females. Thigh and back fillet were more reddish when compared to sirloin cut and tail, regardless of sex. In conclusion, female tail meat provided greater yield and lipid content than males, and this result was statistically significant. These findings can help producers and consumers alike, better understand yield, quality, and nutritional quality of Pantanal caiman meat.

    The Pantanal region is the largest floodplain area in the world and of great biological importance due to its unique flora and fauna. This area is continuously undergoing increasing anthropogenic threats, and has also experienced mercury contamination associated with gold mining and other anthropogenic activities. Pantanal caimans are top-level predators, and, as such, show great potential to accumulate mercury (Hg) by biomagnification. In this study 79 specimens from four locations in the Pantanal were analyzed for total Hg and methyl mercury (MeHg) by cold vapor atomic absorption spectrometry. Total Hg contents ranged from 0.02 to 0.36 µg g(-1) (ww), and most specimens presented MeHg ratios above 70%. One of the sites, impacted by anthropogenic activities, presented significantly higher total Hg in comparison to three less impacted sites, supporting the hypothesis that caimans can, in fact, be considered effective bioindicators of ecosystem health.

    We studied growth of the caiman, Caiman crocodilus yacare, in the Brazilian Pantanal for 27 years between 1987 and 2013.We recaptured 647 of 7769 C. c. yacare initially marked in an area of 50 km(2), in two ranches. We were able to determine size at age accurately for 24 male and17 female caimans that had been marked at hatching or less than 1 year old, and recaptured over periods of 5 to 24 years. The other 606 caimans were used to evaluate short-term growth rates. Age-size relationships were estimated using growth models from the Richards family of curves (full model, von Bertalanffy and monomolecular). The form of the relationships differed between analyses based on caimans of known age and analyses based on integration of growth rate on size relationships for caimans whose ages were not known. Individuals showed large variation in short-term growth rates, but data on known-age animals indicated little between-individual variability in long-term growth rates. There was evidence of a small effect of rainfall, but not temperature, on short-term growth of small caimans, but most variation in growth rates was unexplained by variables other than age and sex. Data on known-age individuals indicated that female C. c. yacare generally reach sexual maturity between 10 and 15 years of age. Because of the asymptotic relationship between age and size, deviations of observations from the model for age are larger than for size, and estimates of age at a given size have greater errors than estimates of size at a given age. Integration of growth rate on size relationships may be adequate for estimating size from age in many cases, but accurate estimates of age from size require data on known-age individuals over the size range of the species.

    Total mercury (Hg) concentrations of muscle, liver, blood, and epidermal keratin were measured in typically consumed, economically and culturally important species of turtle (Podocnemis unifilis and Podocnemis expansa) and caiman (Melanosuchus niger and Caiman crocodilus) from the Rio Purus in the Amazon basin, Brazil. Methylmercury (MeHg) concentrations were also measured in muscle tissue, representing the first analysis of MeHg concentrations in Amazonian reptile species. In muscle tissues Hg was mostly MeHg (79-96%) for all species. No correlations existed between animal size and total Hg or MeHg concentrations for any species other than M. niger, possibly as a result of growth dilution or the evolution of efficient Hg elimination mechanisms. Significant linear correlations were found between total Hg concentrations in all pairs of nonlethally sampled tissues (keratin and blood) and internal tissues (muscle and liver) for M. niger and between keratin and internal tissues for P. expansa, indicating that nonlethally sampled tissues can be analyzed to achieve more widespread and representative monitoring of Hg bioaccumulation in Amazonian reptiles. Although mean Hg concentrations in muscle for all species were below the World Health Organization guideline for safe consumption (500 µg kg(-1)), mean concentrations in caiman liver were above the safe limit for pregnant women and children (200 µg kg(-1)). No significant differences were found between total Hg and MeHg concentrations in tissues from wild-caught and farm-raised P. expansa, suggesting that farming may not reduce Hg exposure to humans. © 2015 SETAC.

    Full Text Available In Brazil, there is increasing interest in the establishment of captive breeding programs for caiman. However, there is a paucity of in-depth studies on the proper care of these reptiles in captivity, particularly regarding optimal food type and frequency of feeding. The purpose of this study was to determine radiographic-anatomical aspects of, and gastrointestinal transit time of Caiman crocodilus crocodilus using contrast radiography. Ten caiman were used in the study, five males and five females, the animals were physically restrained for administration of a radiographic contrast medium, consisting of 10 ml/kg barium sulfate and mineral oil suspension (70%: 30% respectively, via the orogastric tube. Following contrast medium administration, radiographs were taken via dorsoventral projection first at five minutes, then at 6, 24, 30, 48, 54, 72, 80, 96, 104, 120, 130, 144 and 150 hours. This technique allows visualization of contrast medium passage through the GI tract, which enabled determination of gastrointestinal transit time in the spectacled caiman. The average time for contrast medium passage through the digestive tract of this species was 117 ± 29.6 h for females and 86.4 ± 21.5 h for males.

    Hepatozoon species are the most common intracellular hemoparasite found in reptiles. Hepatozoon caimani, whose vectors are Culex mosquitoes, has been detected in a high prevalence among caimans in Brazil by blood smears examinations. The present work aimed to detect and characterize the Hepatozoon spp. found in 33 caimans (24 free-ranging and 9 captive; 28 males and 5 females) (Caiman crocodilus yacare) sampled at Poconé, North Pantanal, state of Mato Grosso, Brazil, using blood smears examinations and molecular techniques. Hepatozoon spp.-gametocytes were found in 70.8% (17/24) and 88.8% (8/9) of blood smears from free-ranging and captive caimans, respectively. Hepatozoon spp. 18S rRNA DNA was found in 79.2% (19/24) and 88.8% (8/9) of free-ranging and captive caimans, respectively. Comparative analysis of parasitized and non-parasitized erythrocytes showed that all analyzed features were significantly different (PPantanal.

    Studies on caiman, Caiman crocodilus chiapasius, in Mexico are scarce. The present study was conducted to evaluate the key characteristics regarding the reproductive ecology of caiman in Mexico. We conducted nest searches from April to September 2014. We observed that nests were built in June and that hatching occurred in September and October. The phase of the moon had an effect on nesting events. The height of the nest, the distance to the nearest tree, and the distance from the top of the nest to the first egg were related to hatching success and incubation temperature. (Author)

    Cold stress syndrome (CSS) in the Florida manatee Trichechus manatus latirostris has been defined as morbidity and mortality resulting from prolonged exposure to water temperatures cases were included in the analyses. There were numerous differences between mean values of TEG and coagulation parameters for healthy manatees and those for CSS cases. Among TEG parameters, reaction time (R), clot formation time (K) and percentage of clot lysed after 30 min (LY30) values were significantly different (p cases also had significantly higher mean D-dimer concentration and coagulation factor XI activity, prolonged mean activated partial thromboplastin time (aPTT) and significantly decreased mean antithrombin activity. These combined abnormalities include clinicopathologic criteria of disseminated intravascular coagulation, indicating an increased risk of thromboembolic disease associated with manatee CSS.

    The in vitro synergistic activity between ciprofloxacin and serum of broad snouted caiman on Escherichia coli was studied. The estimated MIC value of ciprofloxacin was 0.0188 µg/ml, and two assays of kill curve during 5 hours were performed: the first one in a standard culture medium and the second one in the presence of caiman serum. Different concentrations of ciprofloxacin were tested. Ciprofloxacin showed higher values of bacterial elimination rate in the presence of caiman serum in all concentrations tested. The combined activity of sub-inhibitory concentrations of ciprofloxacin and the humoral immune factors present in caiman serum determined an increase in the bacterial elimination observed in this assay. We suggest that the antibacterial activity of complement and natural antibodies present in caiman serum, which can bind to both Gram-negative and Gram-positive bacteria and acting through the classical complement pathway, can inhibit bacterial growth of Escherichia coli by lysis.

    The Neotropical crocodylian species, Caiman crocodilus, is widely distributed through Mesoamerica, northern South America, and the Amazon basin. Four subspecies are recognized within C. crocodilus, suggesting some geographic variation in morphology. In this study, we utilized mitochondrial DNA (mtDNA) sequence data from 45 individuals of C. crocodilus throughout its range to infer its evolutionary history and population structure, as well as to evaluate genealogical support for subspecies and their geographic distributions. Our molecular phylogenetic results identified five mtDNA haplotype clades with a mean sequence divergence of 3.4%, indicating considerable evolutionary independence among phylogeographic lineages. Our results were also broadly consistent with current subspecific taxonomy, with some important additional findings. First, we found substantial genetic structuring within C. c. fuscus from southern Mesoamerica. Second, though we confirmed the existence of a widespread Amazonian clade, we also discovered a cryptic and divergent mtDNA lineage that was indistinguishable from C. c. crocodilus based on external morphology. Third, we confirm the status of C. c. chiapasius as a distinct evolutionary lineage, and provide evidence that C. c. fuscus may be moving northward and hybridizing with C. c. chiapasius in northern Mesoamerica. Finally, our results parallel previous phylogeographic studies of other organisms that have demonstrated significant genetic structure over shorter geographic distances in Mesoamerica compared with Amazonia. We support conservation efforts for all five independent lineages within C. crocodilus, and highlight the subspecies C. c. chiapasius as a unit of particular conservation concern.

The hatched animals were kept under two different temperatures during growth (28ºC and 32°C, and submitted to morphometrical analysis. The collected data were analyzed according to the analysis of variance. The characteristics of the weight of the animals and the width of the head did not present significant differences (P > 0.05 between the treatments. The circumference of the belly and width of snout at nostrils were the ones that had the best (P < 0.05 results at 28°C. The other characteristics as total length, tail length ,snout-vent length ,head length, eye length, snout length, width of snout at mid-point and distance between limbs showed better results at 32°C. It may be concluded that temperature variation did not influence the gain of weight, but the temperature of 32°C was the best for the general development of the animals.

    Relative to many other mammals, little is known about the functional morphology of the four extant species of the order Sirenia. In this study, 166 Florida manatee (Trichechus manatus latirostris) carcasses fresh enough to collect detailed anatomical information were examined to describe the gross anatomy of the diaphragm. Our results show that the Florida manatee's diaphragm differs from those of other mammals in that it: lies in a dorsal plane, rather than in the more typical transverse plane; is located dorsal to the heart and does not attach to the sternum; and attaches medially at the "I"-shaped central tendon to bony projections extending ventrally from the vertebral bodies, forming two distinct hemidiaphragms. The manatee's transverse septum is a separate structure that lies at a right angle to the diaphragm and separates the heart from the liver and other viscera. The extreme muscularity of the diaphragm and the ability of manatees to adjust their position in the water column with minimal external movement suggest that diaphragmatic contractions may change the volume of each pleural cavity to affect buoyancy, roll, and pitch. We also hypothesize that such contractions, in concert with contractions of powerful abdominal muscles, may compress gas in the massive large intestine, and thereby also contribute to buoyancy control.

    Limited information is available regarding the role of minerals and heavy metals in the morbidity and mortality of manatees. Whole-blood and serum mineral concentrations were evaluated in apparently healthy, free-ranging Florida (Trichechus manatus latirostris, n = 31) and Belize (Trichechus manatus manatus, n = 14) manatees. Toxicologic statuses of the animals and of their environment had not been previously determined. Mean mineral whole-blood (WB) and serum values in Florida (FL) and Belize (BZ) manatees were determined, and evaluated for differences with respect to geographic location, relative age, and sex. Mean WB and serum silver, boron, cobalt, magnesium, molybdenum, and WB cadmium concentrations were significantly higher in BZ versus FL manatees (P ≤ 0.05). Mean WB aluminum, calcium, manganese, sodium, phosphorus, vanadium, and serum zinc concentrations were significantly lower in BZ versus FL manatees. Adult manatees had significant and higher mean WB aluminum, manganese, sodium, antimony, vanadium, and serum manganese and zinc concentrations compared to juvenile animals. Significant and lower mean WB and serum silver, boron, cobalt, and serum copper and strontium concentrations were present in adults compared to juveniles (P ≤ 0.05). Females had significant and higher mean WB nickel and serum barium compared to males (P ≤ 0.05). Mean WB arsenic and zinc, and mean serum iron, magnesium, and zinc concentrations fell within toxic ranges reported for domestic species. Results reveal manatee blood mineral concentrations differ with location, age, and sex. Influence from diet, sediment, water, and anthropogenic sources on manatee mineral concentration warrant further investigation.

    Full Text Available Following the bite of Philodryas olfersii latirostris Cope, 1862, a 29-year-old male herpetologist developed localized and burning pain, and minimal bleeding from the puncture marks of posterior maxillary teeth, which subsided rapidly. The victim developed no other local signs or symptoms. After few days the victim presented persistent severe rotatory dizziness, nausea, and vomiting. On examination his hearing was normal. Neurological exam was otherwise normal. The patient had acute vertiginous symptoms but had no associated neurological signs. Computed tomography did not show abnormality. A diagnosis of labyrinthine syndrome was made. It was treated conservatively, and the patient recovered uneventfully. It was assumed as an effect of ophitoxemia. This case may be regarded as an unusual presentation of systemic envenoming following a human bite by Philodryas olfersii latirostris.

    Previous studies showed infections of Hepatozoon caimani in wild populations of caimans in wide regions from Brazil; some of those demonstrated that trophic chain are linked to natural infections through paratenic hosts or by the direct ingestion of vectors. These studies life cycle of H. caimani contributed inestimably to the knowledge of transmission routes, yet but lack enhancement tools for better detail of parasite. This study reports the forms in the blood and tissues, and also partial molecular characterization of the H. caimani following part of the 18S rRNA region. In the southern Pantanal, there were sampling 39 adult caimans (Caiman yacare), where 31 (79.5%) were parasitized by H. caimani. Free gametocytes had an average intensity of 19.6% and intraerythrocytic forms 7.42%, in the blood smears. In stained smears of the liver and lungs of naturally infected caimans which were examined, monozoic and dizoic cysts were found in these tissues, generally next to the vessels. In the histopathology, meronts were observed in the wall of vessels from liver and kidney ducts. Blood samples were forwarded to PCR process and produced amplicons with about 600 and 900 bp, respectively, for the primers HEPF300/HEP900 and HEMO1/HEMO2. This was the first report of molecular confirmation of Hepatozoon in populations of naturally infected caimans of morphological detail of the gametocytes in scanning electron microscopy and histology of merogony in livers and kidneys of C. yacare.

    Florida manatees (Trichechus manatus latirostris) are marine mammals that inhabit the coastal waters and rivers of the southeastern USA, primarily Florida. Previous studies have shown that Florida manatees have low mitochondrial DNA variability, suggesting that nuclear DNA loci are necessary for discriminatory analyses. Here we report 10 polymorphic microsatellite loci with an average of 4.2 alleles per locus, and average heterozygosity of 50.1%. These loci have been developed for use in population studies, parentage assignment, and individual identification. ?? 2007 Blackwell Publishing Ltd.

    Full Text Available Ecological aspects of nesting in Caiman crocodilus chiapasius (Bocourt 1876 in La Encrucijada Biosphere Reserve, Mexico Studies on caiman, Caiman crocodilus chiapasius, in Mexico are scarce. The present study was conducted to evaluate the key characteristics regarding the reproductive ecology of caiman in Mexico. We conducted nest searches from April to September 2014. We observed that nests were built in June and that hatching occurred in September and October. The phase of the moon had an effect on nesting events. The height of the nest, the distance to the nearest tree, and the distance from the top of the nest to the first egg were related to hatching success and incubation temperature.

    Manatees (Trichechus manatus latirostris) in Florida utilize intake and effluent canals of power plants as resting and thermoregulatory habitat. We report the use of a power plant canal in Cuba by a known Florida manatee, the first documented case of movement by a manatee between Florida and Cuba. In January, February, and April 2007, two manatees (mother and calf) were reported entering a power plant canal in north Havana, Cuba. The larger manatee had several distinctive scars which were photographed. Digital images were matched to a previously known Florida manatee (CR131) with a sighting history dating from December 1979 to July 2006. Exchanges of individuals between Florida and Cuba may have important genetic implications, particularly since there appears to be little genetic exchange between the Florida manatee subspecies with populations of the Antillean manatee subspecies (T. m. manatus) in Puerto Rico and the Dominican Republic.

    Our objective was to examine the physico-chemical and sensory attributes of low-sodium restructured caiman steaks containing microbial transglutaminase (MTG) and salt replacers (KCl and MgCl2). Trimmings from caiman carcasses were processed into restructured steaks with or without MTG and salt replacers; the five treatments were CON (1.5% NaCl), T-1 (1.5% NaCl+1% MTG), T-2 (0.75% NaCl+1% MTG+0.75% KCl), T-3 (0.75% NaCl+1% MTG+0.75% MgCl2), and T-4 (0.75% NaCl+1% MTG+0.375% KCl+0.375% MgCl2). T-4 demonstrated the greatest (P0.05) to controls in salty flavor. Our findings suggest that the combination of MTG, KCl, and MgCl2 can be employed as a suitable salt reduction strategy in restructured caiman steaks without compromising sensory attributes and consumer acceptance. © 2013.

    Electrocardiographic (ECG) measurements were recorded in two subspecies of awake, apparently healthy, wild manatees (Trichechus manatus latirostris and T. m. manatus) undergoing routine field examinations in Florida and Belize. Six unsedated juveniles (dependent and independent calves) and 6 adults were restrained in ventral recumbency for ECG measurements. Six lead ECGs were recorded for all manatees and the following parameters were determined: heart rate and rhythm; P, QRS, and T wave morphology, amplitude, and duration; and mean electrical axis (MEA). Statistical differences using a t-test for equality of means were determined. No statistical difference was seen based on sex or subspecies of manatees in the above measured criteria. Statistical differences existed in heart rate (P = 0.047), P wave duration (P = 0.019), PR interval (P = 0.025), and MEA (P = 0.021) between adult manatees and calves. Our findings revealed normal sinus rhythms, no detectable arrhythmias, prolonged PR and QT intervals, prolonged P wave duration, and small R wave amplitude as compared with cetacea and other marine mammals. This paper documents the techniques for and baseline recordings of ECGs in juvenile and adult free-living manatees. It also demonstrates that continual assessment of cardiac electrical activity in the awake manatee can be completed and can be used to aid veterinarians and biologists in routine health assessment, during procedures, and in detecting the presence of cardiac disease or dysfunction.

    Members of the order Sirenia are unique among mammals in being the only totally aquatic herbivores. They display correspondingly specialized physiological, behavioral and anatomical features. There have been few reports concerning sirenian neuroanatomy, and most of these have consisted of gross anatomical observations. Our interest in Sirenia stems from the desire to understand neuroanatomical specializations in the context of behavior and the effort to elucidate trends in mammalian brain evolution. The architecture of frontal regions of cerebral cortex was investigated in several brains of the Florida manatee, Trichechus manatus latirostris. Through observation of sections stained for Nissl substance or myelinated fibers, several distinct cortical areas were identified on the basis of laminar organization. These range from areas with poorly defined laminae to those having 6 well-defined layers, some of which exhibit sublayers. Two cortical areas exhibit pronounced cell clusters in layer VI, and these stain positively for acetylcholinesterase and cytochrome oxidase. We hypothesize that these clusters may be involved in perioral tactile bristle function. Certain of our findings are consistent with previous observations in the literature on the brains of dugongs. On the basis of their lamination patterns, these frontal cortical areas appear to be organized into concentric zones of allocortex, mesocortex and isocortex.

    The Florida manatee, Trichechus manatus latirostris (Sirenia: Trichechidae), is the largest herbivorous marine mammal. Previously, components of the gastrointestinal (GI) tract of the species have been described, but no comprehensive descriptions of the gross and microscopic anatomy existed. This study integrates function and structure of the entire Florida manatee GI tract. The GI tracts of several recently dead Florida manatees were examined from the following viewpoints: gross anatomical studies of preserved and unpreserved specimens, histology and histochemistry, and ultrastructure. The manatee GI tract has an enlarged hindgut, as do other nonruminant herbivores (i.e., hindgut digesters such as horses), but it also has important adaptations not seen in most other mammals. These structural adaptations include a discrete accessory digestive gland (the cardiac gland), submucosal mucous glands along the greater curvature of the stomach, and unkeratinized, stratified squamous epithelial cells overlying the glandular mucosae of the pyloric antrum, midgut cecum, colon, and rectum. The adaptations described above may relate to osmoregulation as well as to herbivory. The Florida manatee GI tract is most similar to those of other members of the Order Sirenia and to that of the herbivorous green sea turtle (Chelonia mydas), but it also shows superficial similarities to those of phylogenetically close Orders, the Proboscidea and Hyracoidea. The immense size of both the manatee and its large intestine suggests that, relative to smaller hindgut digesters, manatees have a slow rate of passage of digesta and efficient breakdown of fibrous plant material.

    The population dynamics of large, long-lived mammals are particularly sensitive to changes in adult survival. Understanding factors affecting survival patterns is therefore critical for developing and testing theories of population dynamics and for developing management strategies aimed at preventing declines or extinction in such taxa. Few studies have used modern analytical approaches for analyzing variation and testing hypotheses about survival probabilities in large mammals. This paper reports a detailed analysis of annual adult survival in the Florida manatee (Trichechus manatus latirostris), an endangered marine mammal, based on a mark-recapture approach. Natural and boat-inflicted scars distinctively 'marked' individual manatees that were cataloged in a computer-based photographic system. Photo-documented resightings provided 'recaptures.' Using open population models, annual adult-survival probabilities were estimated for manatees observed in winter in three areas of Florida: Blue Spring, Crystal River, and the Atlantic coast. After using goodness-of-fit tests in Program RELEASE to search for violations of the assumptions of mark-recapture analysis, survival and sighting probabilities were modeled under several different biological hypotheses with Program SURGE. Estimates of mean annual probability of sighting varied from 0.948 for Blue Spring to 0.737 for Crystal River and 0.507 for the Atlantic coast. At Crystal River and Blue Spring, annual survival probabilities were best estimated as constant over the study period at 0.96 (95% CI = 0.951-0.975 and 0.900-0.985, respectively). On the Atlantic coast, where manatees are impacted more by human activities, annual survival probabilities had a significantly lower mean estimate of 0.91 (95% CI = 0.887-0.926) and varied unpredictably over the study period. For each study area, survival did not differ between sexes and was independent of relative adult age. The high constant adult-survival probabilities estimated

    Full Text Available Nature conservation and agricultural production may be considered as conflicting objectives, but for a wheat and sheep property in Western Australia they have been pivotal management objectives for the last 48 years. Koobabbie, a 7,173 ha property, has retained 41.5% of the original native vegetation, and is a designated Important Bird Area by BirdLife Australia, while still being an economically profitable agricultural enterprise. Since 1987 the owners of Koobabbie have kept detailed records of the avifauna of the property, and encouraged staff from government, non-government and academic organisations to conduct research and monitoring of the endangered Carnaby’s Cockatoo Calyptorhynchus latirostris breeding on their property. In addition, they have instituted control programs for two over-abundant cockatoo species which compete with Carnaby’s Cockatoo for nest sites, and for Feral Cats that are predators of nesting female Carnaby’s Cockatoo and their offspring. This paper presents the results of research and monitoring from 2003-2013, during which seven artificial nesting hollows were erected, and former active nest hollows that had become derelict were repaired. By 2008, the number of breeding pairs on the property was at least 27, but two mass deaths of breeding females in 2009 and 2012 reduced the number of breeding pairs by 80%. This study illustrates the importance of monitoring conservation on private property, and raises a number of issues in relation to management of endangered species dependent on large hollow-bearing trees on private property.

    Non-native suckermouth armored catfishes (Loricariidae) of the genus Pterygoplichthys are now common throughout much of peninsular Florida. In this paper, we present preliminary observations on interactions between a Pterygoplichthys species, tentatively identified as P. disjunctivus (Weber, 1991), and endangered native Florida manatees, Trichechus manatus latirostris (Harlan, 1824), in artesian spring systems in Florida's St. Johns River drainage. The introduced catfish have become abundant in spring habitats, sites used by manatees as winter thermal refuges. In the spring runs, Pterygoplichthys regularly attaches to manatees and grazes the epibiota on their skin. On occasion, dozens of Pterygoplichthys congregate on individual manatees. Manatee responses varied widely; some did not react visibly to attached catfish whereas others appeared agitated and attempted to dislodge the fish. The costs and/or benefits of this interaction to manatees remain unclear.

    Trichechus manatus (West Indian manatee), especially T. m. latirostris, the Florida subspecies, has been the focus of conservation efforts and extensive research since its listing under the Endangered Species Act of 1973. To determine the status of, and severity of threats to, the Florida manatee, a comprehensive revision and update of the manatee Core Biological Model was completed and used to perform a population viability analysis for the Florida manatee. The probability of the Florida manatee population falling below 500 adults on either the Gulf or East coast within the next 100 years was estimated to be 0.42 percent. This risk of quasi-extinction is low because the estimated adult survival rates are high, the current population size is greater than 2,500 on each coast, and the estimated carrying capacity for manatees is much larger than the current abundance estimates in all four regions of Florida. Three threats contribute in roughly equal measures to the risk of quasi-extinction: watercraft-related mortality, red-tide mortality, and loss of warm-water habitat. Only an increase in watercraft-related mortality has the potential to substantially increase the risk of quasi-extinction at the statewide or coastal level. Expected losses of warm-water habitat are likely to cause a major change in the distribution of the population from the regions where manatees rely heavily on power plant effluents for warmth in winter (Southwest and Atlantic regions) to the regions where manatees primarily use natural springs in winter (Northwest and Upper St. Johns regions). The chances are nearly 50 percent that manatee populations in the Southwest and Atlantic regions will decrease from their 2011 levels by at least 30 percent over the next century.A large number of scenarios were examined to explore the possible effects of potential emerging threats, and in most of them, the risk of quasi-extinction at the coastal scale within 100 years did not rise above 1 percent.

    Toxoplasma gondii is a feline protozoan reported to cause morbidity and mortality in manatees and other marine mammals. Given the herbivorous nature of manatees, ingestion of oocysts from contaminated water or seagrass is presumed to be their primary mode of infection. The objectives of this study were to investigate oocyst contamination of seagrass beds in Puerto Rico and determine the seroprevalence of T. gondii in Antillean (Trichechus manatus manatus) and Florida (T. m. latirostris) manatees. Sera or plasma from Antillean (n = 5) and Florida (n = 351) manatees were tested for T. gondii antibodies using the modified agglutination test. No T. gondii DNA was detected via PCR in seagrass samples (n = 33) collected from Puerto Rico. Seroprevalence was 0%, suggesting a lower prevalence of T. gondii in these manatee populations than previously reported. This was the first study to investigate the potential oocyst contamination of the manatee diet, and similar studies are important for understanding the epidemiology of T. gondii in herbivorous marine mammals.

    Cytokines have important roles in the mammalian response to viral and bacterial infections, trauma, and wound healing. Because of early cytokine production after physiologic stresses, the regulation of messenger RNA (mRNA) transcripts can be used to assess immunologic responses before changes in protein production. To detect and assess early immune changes in endangered Florida manatees (Trichechus manatus latirostris), we developed and validated a panel of quantitative PCR assays to measure mRNA transcription levels for the cytokines interferon (IFN)-γ; interleukin (IL)-2, -6, and -10; tumor necrosis factor-α, and the housekeeping genes glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and β-actin (reference genes). Assays were successfully validated using blood samples from free-ranging, apparently healthy manatees from the east and west coasts of central Florida. No cytokine or housekeeping gene transcription levels were significantly different among age classes or sexes. However, the transcription levels for GAPDH, IL-2, IL-6, and IFN-γ were significantly higher (Ptrauma and novel or ongoing environmental stressors.

    The Florida manatee, Trichechus manatus latirostris, is a hindgut-fermenting herbivore. In winter, manatees migrate to warm water overwintering sites where they undergo dietary shifts and may suffer from cold-induced stress. Given these seasonally induced changes in diet, the present study aimed to examine variation in the hindgut bacterial communities of wild manatees overwintering at Crystal River, west Florida. Faeces were sampled from 36 manatees of known sex and body size in early winter when manatees were newly arrived and then in mid-winter and late winter when diet had probably changed and environmental stress may have increased. Concentrations of faecal cortisol metabolite, an indicator of a stress response, were measured by enzyme immunoassay. Using 454-pyrosequencing, 2027 bacterial operational taxonomic units were identified in manatee faeces following amplicon pyrosequencing of the 16S rRNA gene V3/V4 region. Classified sequences were assigned to eight previously described bacterial phyla; only 0.36% of sequences could not be classified to phylum level. Five core phyla were identified in all samples. The majority (96.8%) of sequences were classified as Firmicutes (77.3 ± 11.1% of total sequences) or Bacteroidetes (19.5 ± 10.6%). Alpha-diversity measures trended towards higher diversity of hindgut microbiota in manatees in mid-winter compared to early and late winter. Beta-diversity measures, analysed through permanova, also indicated significant differences in bacterial communities based on the season.

    Manatees are a vulnerable, charismatic sentinel species from the evolutionarily divergent Afrotheria. Manatee health and resistance to infectious disease is of great concern to conservation groups, but little is known about their immune system. To develop manatee-specific tools for monitoring health, we first must have a general knowledge of how the immunoglobulin heavy (IgH) chain locus is organized and transcriptionally expressed. Using the genomic scaffolds of the Florida manatee (Trichechus manatus latirostris), we characterized the potential IgH segmental diversity and constant region isotypic diversity and performed the first Afrotherian repertoire analysis. The Florida manatee has low V(D)J combinatorial diversity (3744 potential combinations) and few constant region isotypes. They also lack clan III V segments, which may have caused reduced VH segment numbers. However, we found productive somatic hypermutation concentrated in the complementarity determining regions. In conclusion, manatees have limited IGHV clan and combinatorial diversity. This suggests that clan III V segments are essential for maintaining IgH locus diversity.

    Environmental and anthropogenic stressors can affect wildlife populations in a number of ways. For marine mammals (e.g. the Florida manatee Trichechus manatus latirostris), certain stressors or conservation risk factors have been identified, but sublethal effects have been very difficult to assess using traditional methods. The development of 'biomarkers' allows us to correlate effects, such as impaired reproduction, with possible causes. A recently developed biomarker (anti-Müllerian hormone, AMH) provides an enzyme-linked immunosorbent assay of gonadal function. The study objective was to determine AMH levels in wild manatees. In total, 28 male and 17 female manatee serum samples were assayed. Animal demographics included collection date, body weight (kg) and total length (cm). In certain cases, age of individuals was also known. AMH levels ranged from 160 to 2451.85 ng ml-1 (mean = 844.65 ng ml-1) in males and 0.00 to 0.38 ng ml-1 (mean = 0.10 ng ml-1) in females. Linear regression analyses revealed a significant relationship between male AMH levels and body weight (R2 = 0.452; p 2 = 0.338; p < 0.001). Due to the small sample size, regression analyses for female AMH and body weight and length were not significant. This represents the first report of AMH detection in a marine mammal. AMH levels in male manatees are the highest of any species observed to date, whereas levels in females are within reported ranges. Further studies will promote improved conservation decision by assessing AMH levels in the manatee as a function of various stressors including, but not limited to, nutritional status, serious injuries (e.g. watercraft collisions), exposure to biotoxins or contaminants, or disease.

    Purussaurus brasiliensis thrived in the northwestern portion of South America during the Late Miocene. Although substantial material has been recovered since its early discovery, this fossil crocodilian can still be considered as very poorly understood. In the present work, we used regression equations based on modern crocodilians to present novel details about the morphometry, bite-force and paleobiology of this species. According to our results, an adult Purussaurus brasiliensis was estimated to reach around 12.5 m in length, weighing around 8.4 metric tons, with a mean daily food intake of 40.6 kg. It was capable of generating sustained bite forces of 69,000 N (around 7 metric tons-force). The extreme size and strength reached by this animal seems to have allowed it to include a wide range of prey in its diet, making it a top predator in its ecosystem. As an adult, it would have preyed upon large to very large vertebrates, and, being unmatched by any other carnivore, it avoided competition. The evolution of a large body size granted P. brasiliensis many advantages, but it may also have led to its vulnerability. The constantly changing environment on a large geological scale may have reduced its long-term survival, favoring smaller species more resilient to ecological shifts. PMID:25689140

    Trypanosoma naviformis n. sp. is described from the African olive sunbird Cyanomitra olivacea in Ghana based on the morphology of its hematozoic trypomastigotes and partial sequences of the small subunit ribosomal RNA gene. This parasite belongs to the group of small non-striated avian trypanosomes (< 30 µm in length in average) with the kinetoplast situated close to the posterior end of the body. Trypanosoma naviformis can be distinguished from other small avian trypanosomes due to its poorly visible flagellum, central position of its nucleus, and the symmetrically (in relation to the nucleus) narrowing of both ends of the hematozoic trypomastigotes, which are boat-like in shape. Illustrations of trypomastigotes of the new species are given, and SSU rDNA lineages associated with this parasite are documented. This parasite has been reported in Ghana and Cameroon and was also found in the yellow-whiskered greenbul, Andropadus latirostris in these countries. It appears to be widespread in its range given the distribution of these bird species in Africa.

    This report provides supporting details and evidence for the rationale, validity and efficacy of a new mark-recapture model, the Barker Robust Design, to estimate regional manatee survival rates used to parameterize several components of the 2012 version of the Manatee Core Biological Model (CBM) and Threats Analysis (TA).  The CBM and TA provide scientific analyses on population viability of the Florida manatee subspecies (Trichechus manatus latirostris) for U.S. Fish and Wildlife Service’s 5-year reviews of the status of the species as listed under the Endangered Species Act.  The model evaluation is presented in a standardized reporting framework, modified from the TRACE (TRAnsparent and Comprehensive model Evaluation) protocol first introduced for environmental threat analyses.  We identify this new protocol as TRACE-MANATEE SURVIVAL and this model evaluation specifically as TRACE-MANATEE SURVIVAL, Barker RD version 1. The longer-term objectives of the manatee standard reporting format are to (1) communicate to resource managers consistent evaluation information over sequential modeling efforts; (2) build understanding and expertise on the structure and function of the models; (3) document changes in model structures and applications in response to evolving management objectives, new biological and ecological knowledge, and new statistical advances; and (4) provide greater transparency for management and research review.

    The Australian dugong (Dugong dugon) and Florida manatee (Trichechus manatus latirostris) are threatened species of aquatic mammals in the order Sirenia. Sirenian conservation and management actions would benefit from a more complete understanding of genetic diversity and population structure. Generally, species-specific microsatellite markers are employed in conservation genetic studies; however, robust markers can be difficult and costly to isolate. To increase the number of available markers, dugong and manatee microsatellite primers were evaluated for cross-species amplification. Furthermore, one manatee and four dugong novel primers are reported. After polymerase chain reaction optimization, 23 (92%) manatee primers successfully amplified dugong DNA, of which 11 (48%) were polymorphic. Of the 32 dugong primers tested, 27 (84%) yielded product in the manatee, of which 17 (63%) were polymorphic. Dugong and manatee primers were compared and the most informative markers were selected to create robust and informative marker-panels for each species. These cross-species microsatellite marker-panels can be employed to assess other sirenian populations and can provide beneficial information for the protection and management of these unique mammals.

    Full Text Available The legal Pantanal caiman (Caiman crocodilus yacare farming, in Brazil, has been stimulated and among meat preservation techniques the salting process is a relatively simple and low-cost method. The objective of this work was to study the sodium chloride diffusion kinetics in farmed caiman muscle during salting. Limited volumes of brine were employed, with salting essays carried at 3, 4 and 5 brine/muscle ratios, at 15%, 20% and 25% w/w brine concentrations, and brine temperatures of 10, 15 and 20ºC. The analytical solution of second Fick's law considering one-dimensional diffusion through an infinite slab in contact with a well-stirred solution of limited volume was used to calculate effective salt diffusion coefficients and to predict the sodium chloride content in the fillets. A good agreement was obtained between the considered analytical model and experimental data. Salt diffusivities in fillets were found to be in the range of 0.47x10-10 to 9.62x10-10 m²/s.A criação de jacaré do Pantanal (Caiman crocodilus yacare em cativeiro tem sido estimulada, e entre as técnicas de processamento de sua carne, a salga é um processo de conservação relativamente simples e de baixo custo.

    In contrast to other vertebrate hemoglobins (Hbs) whose high intrinsic O2 affinities are reduced by red cell allosteric effectors (mainly protons, CO2, organic phosphates, and chloride ions), crocodilian Hbs exhibit low sensitivity to organic phosphates and high sensitivity to bicarbonate (HCO3−), which is believed to augment Hb-O2 unloading during diving and postprandial alkaline tides when blood HCO3− levels and metabolic rates increase. Examination of α- and β-globin amino acid sequences of dwarf caiman (Paleosuchus palpebrosus) revealed a unique combination of substitutions at key effector binding sites compared with other vertebrate and crocodilian Hbs: β82Lys→Gln, β143His→Val, and β146His→Tyr. These substitutions delete positive charges and, along with other distinctive changes in residue charge and polarity, may be expected to disrupt allosteric regulation of Hb-O2 affinity. Strikingly, however, P. palpebrosus Hb shows a strong Bohr effect, and marked deoxygenation-linked binding of organic phosphates (ATP and DPG) and CO2 as carbamate (contrasting with HCO3− binding in other crocodilians). Unlike other Hbs, it polymerizes to large complexes in the oxygenated state. The highly unusual properties of P. palpebrosus Hb align with a high content of His residues (potential sites for oxygenation-linked proton binding) and distinctive surface Cys residues that may form intermolecular disulfide bridges upon polymerization. On the basis of its singular properties, P. palpebrosus Hb provides a unique opportunity for studies on structure-function coupling and the evolution of compensatory mechanisms for maintaining tissue O2 delivery in Hbs that lack conventional effector-binding residues.

    Full Text Available A exploração comercial de jacaré-do-Pantanal (Caiman yacare constitui importante cadeia produtiva no Estado de Mato Grosso. As características nutricionais e representatividade na massa corporal de crocodilianos tornaram a região da cauda objeto de estudos morfofisiológicos, evolutivos e tecnológicos. Como inexiste a caracterização anatômica dos músculos e ossos que constituem os cortes comerciais dessa região, objetivou-se descrever os músculos e correspondentes bases ósseas da cauda. Na descrição óssea, foram utilizados um exemplar adulto e seis juvenis. Para caracterização muscular, 24 espécimes juvenis foram conservados em freezer e dissecados a fresco, em ambos os antímeros, para verificação de simetria de ocorrência, fixações musculares, relacões de sintopia, forma e arquitetura muscular. As vértebras caudais são procélicas, exceto a primeira da série, e possuem na superfície ventral do corpo áreas para articulação com os processos hemais, exceto a primeira e as quatro ou cinco últimas. Os cortes comerciais da região são o filé de cauda, composto pelos músculos semiespinhal caudal, longuíssimo caudal, ilioisquiocaudal, caudofemoral longo, transverso e profundo da cauda, enquanto o corte ponta de cauda é constituído pelos músculos longuíssimo caudal e ilioisquiocaudal, com as cinco ou seis últimas vértebras caudais.

    Seasonal changes in light, temperature, and food availability stimulate a physiological response in an animal. Seasonal adaptations are well studied in Arctic, Sub-Arctic, and hibernating mammals; however, limited studies have been conducted in sub-tropical species. The Florida manatee (Trichechus manatus latirostris), a sub-tropical marine mammal, forages less during colder temperatures and may rely on adipose stores for maintenance energy requirements. Metabolic hormones, growth hormone (GH), insulin-like growth factor (IGF)-I, and ghrelin influence growth rate, accretion of lean and adipose tissue. They have been shown to regulate seasonal changes in body composition. The objective of this research was to investigate manatee metabolic hormones in two seasons to determine if manatees exhibit seasonality and if these hormones are associated with seasonal changes in body composition. In addition, age related differences in these metabolic hormones were assessed in multiple age classes. Concentrations of GH, IGF-I, and ghrelin were quantified in adult manatee serum using heterologous radioimmunoassays. Samples were compared between short (winter) and long (summer) photoperiods (n = 22 male, 20 female) and by age class (adult, juvenile, and calf) in long photoperiods (n = 37). Short photoperiods tended to have reduced GH (p = 0.08), greater IGF-I (p = 0.01), and greater blubber depth (p = 0.03) compared with long photoperiods. No differences were observed in ghrelin (p = 0.66). Surprisingly, no age related differences were observed in IGF-I or ghrelin concentrations (p > 0.05). However, serum concentrations of GH tended (p = 0.07) to be greater in calves and juveniles compared with adults. Increased IGF-I, greater blubber thickness, and reduced GH during short photoperiod suggest a prioritization for adipose deposition. Whereas, increased GH, reduced blubber thickness, and decreased IGF-I in long photoperiod suggest prioritization of lean tissue

    Watercraft-related trauma is the predominant cause of human-induced mortality in manatees (Trichechus manatus latirostris), a federal- and state-listed endangered species. Pyothorax (documented in this case report) and other secondary infections are common sequelae of inhalation of water and the open wounds caused by boat propellers. These secondary infections can lead to the demise of the animal weeks to months after the traumatic incident when external wounds have healed. Diagnosis of underlying disease on physical examination during capture and restraint can be difficult. Acute phase proteins, including serum amyloid A, fibrinogen, and albumin can be used to diagnose inflammatory disease in manatees and improve quality of medical care and husbandry. We also provide the first report of polycystic kidneys in Sirenians.

    Full Text Available Microsatellites are genomic sequences comprised of tandem repeats of short nucleotide motifs widely used as molecular markers in population genetics. FullSSR is a new bioinformatic tool for microsatellite (SSR loci detection and primer design using genomic data from NGS assay. The software was tested with 2000 sequences of Oryza sativa shotgun sequencing project from the National Center of Biotechnology Information Trace Archive and with partial genome sequencing with ROCHE 454® from Caiman latirostris, Salvator merianae, Aegla platensis, and Zilchiopsis collastinensis. FullSSR performance was compared against other similar SSR search programs. The results of the use of this kind of approach depend on the parameters set by the user. In addition, results can be affected by the analyzed sequences because of differences among the genomes. FullSSR simplifies the detection of SSRs and primer design on a big data set. The command line interface of FullSSR was intended to be used as part of genomic analysis tools pipeline; however, it can be used as a stand-alone program because the results are easily interpreted for a nonexpert user.

Of each kind meat were analyzed 6 samples, where were studied counts of mesophilic aerobic bacteria, aerobic bacteria psichrophilic, coliforms, Escherichia coli and Staphylococcus spp., and protein and fat analysis. The results of aerobic mesophilic bacteria ranged between <1.0 a 3.6 log CFU/g, being the biggest counting in ostrich meat. The meat that had the biggest counting of micro-organisms psychrotrophs was also the ostrich, but even so, it was not considered high, ranging between 2.3 and 2.7 log CFU/g. There were no counting for coliforms and E. coli on wild boar and alligator meats (except sample 4 of wild boar meat that had a count of 1.0 log CFU/g of coliforms but, all ostrich meat had count, ranged between 1.3 a 2.7 log CFU/g.

    Full Text Available General histology of small intestine (duodenum and jejunum and the large intestine (colon and cloaca of C. c. yacare (Daudin, 1802 Crocodilia-Reptilia. A comparative description is made of the histology of the small and large intestine of C. c. yacare. In all segments mucosa, submucosa, muscularis and serosa tunics were observed. The duodenum as very long villi, wich are well-developed and attached together to form irregular transverse ridges, covered with simple columnar epithelium with marginal and goblet cells. In the jejunum, the villi are shorter and less frequent. The colon as few folds, covered with the same epithelium; the lamina própria contains straight tubular glands with absortive cells, goblet and Paneth cells. The cloaca is very complex, with three well-defined regions: coprodeum, urodeum and proctodeum. In the coprodeum, the wall is folded, less muscular and the thin mucosa is covered by an epithelium with a few basal cells and mucosal cells. The urodeum as an additional external muscular tunic, with striated muscle fibers and a stritifield cylindrical epithelium with goblet cells. The proctodeum includes the free part of the penis in the male and, laterally, the ducts of a pair of holocrine cloacal glands. Near the opening of the ducts, the epithelium changes to a squamous keratinized type.

    Manatees live in shallow, frequently turbid waters. The sensory means by which they navigate in these conditions are unknown. Poor visual acuity, lack of echolocation, and modest chemosensation suggest that other modalities play an important role. Rich innervation of sensory hairs that cover the entire body and enlarged somatosensory areas of the brain suggest that tactile senses are good candidates. Previous tests of detection of underwater vibratory stimuli indicated that they use passive movement of the hairs to detect particle displacements in the vicinity of a micron or less for frequencies from 10 to 150 Hz. In the current study, hydrodynamic stimuli were created by a sinusoidally oscillating sphere that generated a dipole field at frequencies from 5 to 150 Hz. Go/no-go tests of manatee postcranial mechanoreception of hydrodynamic stimuli indicated excellent sensitivity but about an order of magnitude less than the facial region. When the vibrissae were trimmed, detection thresholds were elevated, suggesting that the vibrissae were an important means by which detection occurred. Manatees were also highly accurate in two-choice directional discrimination: greater than 90% correct at all frequencies tested. We hypothesize that manatees utilize vibrissae as a three-dimensional array to detect and localize low-frequency hydrodynamic stimuli.

  6. Resultative Predicates in Japanese

    Directory of Open Access Journals (Sweden)

    Kaori Takamine

    2007-12-01

    Full Text Available Washio (1997; 1999 observes that resultative predicates are divided into two different groups, strong and weak resultatives, depending on ‘patienthood’ of the object. This typology of resultatives seems to capture a point of crosslinguistic variation in resultatives; Japanese has weak but not strong resultatives, while English has both. Washio also observes that there is another group of examples that bears a superficial resemblance to resultatives but constitutes a different phenomenon, hence spurious resultatives. The difference between weak and strong resultatives is made in terms of the ‘affectedness’ of the verb. Thus the typology of resultatives proposed by Washio is semantically grounded. In this paper, I propose: (i a fine-grained distinction for Washio’s weak resultatives: (ii a syntactic analysis of the different resultative types. On the basis of syntactic evidence, I argue that there are two types of weak resultatives, an adjunct of VP and a complement of VP within the vP projection. I also argue that spurious resultatives are structurally higher than weak resultatives in Japanese.

    I will summarize the physics results from the Tevatron experiments with particular emphasis on the experimental methods used in different kinds of analysis. In particular, the Tevatron is a proton-antiproton collider that has now accumulated more than 2 fb^-1 of luminosity in the two experiments, called CDF and D0. In this lecture I will review the results on inclusive productions of jets, W- and Z-bosons, the results in the flavor sector, the measurements of top production, searches for Higgs boson production and searches for physics beyond the Standard Model. In each case I will explain the basic experimental concepts and methods needed for making the measurement.

    Full Text Available Hypospadias urethroplasty is considered difficult as the complications and unfavourable results are not uncommon. At the turn of the century, due to a better understanding of applied anatomy of hypospadias, new techniques were developed which significantly brought down the complication rate. However unfavourable results are still disturbing. An algorithm for selection of surgery has been presented. Forty three secondary surgeries were performed over 3 years for correction of unfavourable results. The urethrocutaneous fistula was the most common (21% followed by meatal stenosis (14% and narrow neourethra (14%. Common unfavourable results have been discussed. On the basis of experience with a large number of hypospadias urethroplasty ′tips to avoid or minimise unfavourable results′ have been presented. However, one should assess the final outcome of urethroplasty using hypospadias objective scoring evaluation.

    The most precise determination of Vus comes from semileptonic kaon decays. We have measured with the KLOE detector at DAFNE, the Frascati phi-factory, all the experimental inputs to Vus for both neutral and charged kaons. Using our results we extract the value of Vus with ~0.9% fractional error, which is dominated by the theoretical error on the form factor, f+(0). A new determination of the ratio Vus/Vud is also presented, based on our precise measurement of the absolute branching ratio for the decay K -> mu nu (gamma), combined with lattice results for the ratio f_K/f_pi. New results on CPT symmetry and quantum mechanics test have also been achieved, which are based on the first measurement of the charged asymmetry for KS -> pi e nu decay and on interferometry studies using the phi -> KL KS -> pi+ pi- pi+ pi-.

    Morbid obesity is a life-threatening disease that has reached epidemic proportions, especially in the upper midwestern part of the USA. The surgical treatment of morbid obesity is generally effective while the non-surgical treatment is usually not effective. Yet many of our colleagues and much of the public have not accepted these facts for a variety of reasons. Chief among them is the perception that we, as bariatric surgeons, do not really know our results. At times we have been too quick to report on a few early spectacular results, and much too slow to come forward with poor results. We can do something about this. My purpose today is to examine the way in which we should report our results. In approaching a subject, one can take a historical, a philosophical or a scientific approach, but I am not a historian, a philosopher or a statistician. With this denial, I will now feel perfectly comfortable to dabble in all three areas. Historically, I recall that the bearer of bad news is forever an orphan. Philosophically, it is the open mouth that catches the flies. In spite of these warnings, I propose to examine the subject by asking and answering, at least to some extent, a series of questions. Some answers are more obvious and shorter than others.

    Full Text Available The CMS experiment obtained a large number of groundbreaking results from the analysis of 7- and 8-TeV proton-proton collisions produced so far by the Large Hadron Collider at CERN. In this brief summary only a few of those results will be discussed. The new scalar discovered in 2012 has been studied in detail and all its characteristics have been found in agreement with standard model predictions for a Brout-Englert-Higgs boson. The large sample of top quark events collected in 2011 and 2012 have allowed world-class measurements of its mass; the combination of those results is Mt = 173.49 ± 0.36 ± 0.91 GeV. The rare decay Bs0 → μμ has been observed and found in agreement with standard model predictions; the search for the rare decay B0 → μμ has allowed to set a 95% CL limit on the branching fraction at 1.1 × 10−9. These two results strongly constrain new physics models.

  17. [The applicability of results].

    Marín-León, I

    2015-11-01

    The ultimate aim of the critical reading of medical literature is to use the scientific advances in clinical practice or for innovation. This requires an evaluation of the applicability of the results of the studies that have been published, which begins with a clear understanding of these results. When the studies do not provide sufficient guarantees of rigor in design and analysis, the conditions necessary for the applicability of the results are not met; however, the fact that the results are reliable is not enough to make it worth trying to use their conclusions. This article explains how carrying out studies in experimental or artificial conditions often moves them away from the real conditions in which they claim to apply their conclusions. To evaluate this applicability, the article proposes evaluating a set of items that will enable the reader to determine the likelihood that the benefits and risks reported in the studies will yield the least uncertainty in the clinical arena where they aim to be applied.

    Detector packages were exposed on the European Retrievable Carrier (EURECA) as part of the Biostack experiment inside the Exobiology and Radiation Assembly (ERA) and at several locations around EURECA. The packages consist of different plastic nuclear track detectors, nuclear emulsions and thermoluminescence dosimeters (TLD`s). Evaluation of these detectors yields data on absorbed dose and particle and LET spectra. Preliminary results of absorbed dose measurements in the EURECA dosimeter packages are reported and compared to results of the LDEF experiments. The highest dose rate measured on EURECA is 63.3 plus or minus 0.4 mGy d(exp -1) behind a shielding thickness of 0.09 g cm(exp -2) in front of the detector package.

    Full Text Available OBJECTIVE: Evaluate the surgical results of axis screw instrumentation. METHODS: Retrospective evaluation of the clinical and radiological data of patients submitted to axis fixation using screws. RESULTS: Seventeen patients were surgically treated. The mean age was 41.8 years (range: 12-73. Spinal cord trauma was the most common cause of instability (8 patients - 47%. Bilateral axis fixation was performed in all cases, except one, with laminar screw (total of 33 axis screws. Seven patients (41.1% underwent bilateral pars screws; laminar screws were used in six cases and pedicular screws were used in two. In two cases, we performed a hybrid construction (laminar + pars and pedicle + pars. There was no neurological worsening or death, nor complications directly related to use axis screws. CONCLUSION: Axis instrumentation was effective and safe, regardless of the technique used for stabilization. Based on our learnt experience, we proposed an algorithm to choose the best technique for axis screw fixation.

    We present a status report and early commissioning results for FLITECAM, the 1-5 micron imager and spectrometer for SOFIA (the Stratospheric Observatory for Infrared Astronomy). In February 2014 we completed six flights with FLITECAM mounted in the FLIPO configuration, a co-mounting of FLITECAM and HIPO (High-speed Imaging Photometer for Occultations; PI Edward W. Dunham, Lowell Observatory). During these flights, the FLITECAM modes from ~1-4 μm were characterized. Since observatory verification flights in 2011, several improvements have been made to the FLITECAM system, including the elimination of a light leak in the FLITECAM filter wheel enclosure, and updates to the observing software. We discuss both the improvements to the FLITECAM system and the results from the commissioning flights, including updated sensitivity measurements. Finally, we discuss the utility of FLITECAM in the FLIPO configuration for targeting exoplanet transits.

  3. Explaining embodied cognition results.

    Science.gov (United States)

    Lakoff, George

    2012-10-01

    From the late 1950s until 1975, cognition was understood mainly as disembodied symbol manipulation in cognitive psychology, linguistics, artificial intelligence, and the nascent field of Cognitive Science. The idea of embodied cognition entered the field of Cognitive Linguistics at its beginning in 1975. Since then, cognitive linguists, working with neuroscientists, computer scientists, and experimental psychologists, have been developing a neural theory of thought and language (NTTL). Central to NTTL are the following ideas: (a) we think with our brains, that is, thought is physical and is carried out by functional neural circuitry; (b) what makes thought meaningful are the ways those neural circuits are connected to the body and characterize embodied experience; (c) so-called abstract ideas are embodied in this way as well, as is language. Experimental results in embodied cognition are seen not only as confirming NTTL but also explained via NTTL, mostly via the neural theory of conceptual metaphor. Left behind more than three decades ago is the old idea that cognition uses the abstract manipulation of disembodied symbols that are meaningless in themselves but that somehow constitute internal "representations of external reality" without serious mediation by the body and brain. This article uniquely explains the connections between embodied cognition results since that time and results from cognitive linguistics, experimental psychology, computational modeling, and neuroscience.

    The U.S. Nuclear Regulatory Commission (NRC), Office of Nuclear Regulatory Research, is funding the Idaho National Engineering Laboratory (INEL) in performing research to provide technical input for their use in evaluating responses to Generic Letter 95-07, {open_quotes}Pressure Locking and Thermal Binding of Safety-Related Power-Operated Gate Valves.{close_quotes} Pressure locking and thermal binding are phenomena that make a closed gate valve difficult to open. This paper discusses only the pressure locking phenomenon in a flexible-wedge gate valve; the authors will publish the results of their thermal binding research at a later date. Pressure locking can occur when operating sequences or temperature changes cause the pressure of the fluid in the bonnet (and, in most valves, between the discs) to be higher than the pressure on the upstream and downstream sides of the disc assembly. This high fluid pressure presses the discs against both seats, making the disc assembly harder to unseat than anticipated by the typical design calculations, which generally consider friction at only one of the two disc/seat interfaces. The high pressure of the bonnet fluid also changes the pressure distribution around the disc in a way that can further contribute to the unseating load. If the combined loads associated with pressure locking are very high, the actuator might not have the capacity to open the valve. The results of the NRC/INEL research discussed in this paper show that the relationship between bonnet pressure and pressure locking stem loads appears linear. The results also show that for this valve, seat leakage affects the bonnet pressurization rate when the valve is subjected to thermally induced pressure locking conditions.

    The heavy-ion programme in the ATLAS experiment at the Large Hadron Collider aims to probe and characterise hot and dense matter created in relativistic lead-lead collisions. Moreover, smaller collision systems involving nuclei and hadrons are of interest to disentangle initial- from final-state effects. This report presents new results based on lead-lead and proton-proton data collected at √sNN = 5.02 TeV in 2015, including measurements of bulk collectivity, charged-particle production, electroweak bosons, photon-jet correlations, and quarkonium suppression. First attempts to measure electromagnetic processes in ultra-peripheral collisions are also discussed.

    The PAMELA satellite experiment was launched into low earth orbit on June 15th 2006. The combination of a permanent magnet silicon strip spectrometer and a silicon-tungsten imaging calorimeter allows precision studies of the charged cosmic radiation to be conducted over a wide energy range (100 MeV - several hundred GeV). A primary scientific goal is to search for dark matter particle annihilation by measuring the energy spectra of cosmic ray antiparticles. Latest results from the PAMELA experiment are presented with a particular focus on cosmic ray antiprotons and positrons.

    Full Text Available Pollicisation of the index finger is perhaps one of the most complex and most rewarding operations in hand and plastic surgery. It however has a steep learning curve and demands very high skill levels and experience. There are multiple pitfalls and each can result in an unfavourable result. In essence we need to: Shorten the Index, recreate the carpo metacarpal joint from the metacarpo phalangeal (MP joint, rotate the digit by about 120° for pulp to pulp pinch, palmarly abduct by 40-50° to get a new first web gap, Shorten and readjust the tension of the extensors, re attach the intrinsics to form a thenar eminence capable of positioning the new thumb in various functional positions and finally close the flaps forming a new skin envelope. The author has performed over 75 pollicisations personally and has personal experience of some of the issues raised there. The steps mentioned therefore are an algorithm for helping the uninitiated into these choppy waters.

    The BISTRO Survey (B-fields in Star-forming Region Observations) is one of the six next generation Large Programmes currently being carried out on the JCMT. It is the only Large Programme that is using the new SCUBA2 polarimeter POL2. This exciting programme plans to map the densest regions of all of the nearby star-forming regions within the Gould Belt, to measure the magnetic field orientation and strength in all of these regions. We will present the latest results from the BISTRO survey - a large programme using SCUBA2 and POL2 on JCMT. We will show the structure of the B-fields in several nearby Gould Belt star-forming regions, including Orion, Serpens and Ophiuchus. We will compare our results to various model predictions and theoretical simulations. The ultimate goals of the BISTRO programme are to understand dust grain alignment mechanisms, to compare the data to models of magnetic field geometry, and to explore the relations between fields and filaments, turbulence, outflows, and core geometries. We will comment on these topics.

    With the increase in center-of-mass energy, a new energy frontier has been opened by the Large Hadron Collider. More than 25 fb^-1 of proton-proton collisions at sqrt(s)=13 TeV have been delivered to both ATLAS and CMS experiments during 2016. This enormous dataset can be used to test the Standard Model in a complete new regime with tremendous precision and it has the potential to unveil new physics or set strong bounds on it. In this talk some of the most recent results made public by the CMS Collaboration will be presented. The focus will mainly be on searches for physics beyond the Standard Model, with particular emphasis on searches for dark matter candidates.

    The work carried out over the past three years on FRECOPA and the LDEF has enabled a large quantity of information to be collected, part of which has already been exploited. As far as CNES is concerned, the major spin-offs of this mission mainly focus on the orbital environment and the behavior of materials in such an environment. With respect to the environment, the authors shall develop the lessons learned from expert appraisals on impacts by microparticles, which are the main feature observed in this area. As for the materials, the results show a variety of behavior when subjected to the space environment and even now constitute a wealth of information for the designing and validation of future mechanical systems. Apart from these direct spin-offs, there are repercussions on in-flight and ground testing, the calibration of test benches and improvements to simulation models.

    Full Text Available Operating 40 km off the coast of France since 2007, the ANTARES detector is the largest deep-sea neutrino telescope in the Northern Hemisphere with an instrumented volume of more than 0.01 cubic kilometers. It consists of an array of 885 photomultipliers detecting the Cherenkov light induced by charged leptons produced by neutrino interactions in and around the detector. The primary goal of ANTARES is to search for astrophysical neutrinos in the TeV–PeV range. This comprises generic searches for any diffuse cosmic neutrino flux as well as more specific searches for astrophysical galactic and extragalactic sources. The search program also includes multi-messenger analyses based on time and/or space coincidences with other cosmic probes. The ANTARES observatory is sensitive to a wide-range of other phenomena, from atmospheric neutrino oscillations to dark matter annihilation. In this contribution, recent results from the ANTARES neutrino telescope will be presented.

    With the LHC start-up and the first runs at 900 GeV, 2.36 TeV and 7 TeV centre-of-mass energy in the years 2009 and 2010, the ATLAS detector started to record its first collision events. The integrated luminosity has now reached one inverse pico barn. These data have been used to perform detailed studies on the performance of the detector, including measuring charged and neutral particle mass resonances and the study of QCD cross-sections. The data have already made it possible to commission and calibrate the various ATLAS subdetectors, and understand their performance in detail. The first observation of Standard Model electroweak processes, in particular mass resonances, is also being used as a benchmark for validating the analysis and simulation tools. The status and performance of the detector will be briefly reviewed, the latest physics results will be summarized and limits on new physics will be given.

    COMPASS has accumulated so far 3 years of data, using the 160 GeV polarized muon beam from CERN and a polarized deuterium target to study the spin structure of the nucleon. The most precise determination of the gluon polarization is obtained at $x_{g}=$ 0.085 and a QCD scale $\\mu^{2} =$ 3 GeV$^{2}$, from the high $p_{T}$ hadron pair channel at Q$^{2} $ 1, and the other, data from the production of charmed D$^{0}$ mesons. New data on the spin structure function $g_{1}$ and results from a NLO QCD global analysis are presented A measurement of the Collins asymmetry on deuterium, linked to the transversely polarized parton distributions, is shown. Finally, major upgrades of the spectrometer are launched in view of the 2006 run.

    Full Text Available The HERMES experiment has collected a wealth of deep-inelastic scattering data using the 27.6 GeV polarized lepton beam at HERA and various pure gas targets, both unpolarized and polarized. This allowed for a series of diverse and unique measurements. Among them are measurements that provide information on the threedimensional structure of the nucleon, both in momentum space and in position space. Results of measurements of exclusive ω production on an unpolarized and transversely polarized nucleon target, sensitive to the distribution in transverse-position and longitudinalmomentum space, are discussed as well as the three-dimensional extraction of azimuthal asymmetries measured in semi-inclusive deep-inelastic scattering, sensitive to twist-2 and twist-3 distributions in three-dimensional momentum space.

    This report discusses work being carried out in Norway to promote energy efficiency and the production of new renewable energy. An overall review of the quantifiable results of last year's activities at national level is available. It will serve to initiate an annual reporting tradition. The report represents a step towards an ongoing process for improved targeting and management of national efforts. During the course of the year 2000, NVE has evaluated and adjusted its activities and established a system involving indicators and reporting procedures. It is also important to take notice of the long-term work being undertaken to influence people's attitudes, even though this work is difficult to assess. NVE is investing in i.a. measures aimed at children and young people. Apart from directly influencing future energy users, this investment is also having an effect due to the children's encouragement of their parents to engage in more energy and environment-friendly behaviour. Published in 2000, the IEA report ''Trends in Norwegian Stationary Energy Use'' shows that total Norwegian energy consumption per GDP is not much higher than in other IEA countries, when adjusted for cold climate and industrial structure. However, Norwegians do stand out as intensive users of electricity. The IEA report shows a reduction of 10 TWh in energy usage when compared to the projected post 1990 figures. Energy efficiency activities have contributed towards this reduction. However, the potential for a more rational use of energy in Norway is still substantial and well documented. Based on experience most enterprises could save around 10% of energy used just by making changes to their operations, i.e. without major investments. Furthermore, the potential is growing because of massive technological developments in respect of energy usage, production and distribution. With this in mind, it is necessary to take full advantage of the extensive knowledge

    2011-01-01

    Background The renewed popularity of resurfacing hip arthroplasty in the last 10 years has generated a remarkable quantity of scientific contributions based on mid- and short-term follow-up. More than one paper has reported a consistent early revision rate as a consequence of biological or biomechanical failure. Two major complications are commonly described with resurfacing implants: avascular necrosis and femoral-neck fracture. A close relationship between these two events has been suggested, but not firmly demonstrated, whereas cementing technique seems to be better understood as potential cause of failure. Methods We performed an in vitro study in which four different resurfacing implants were evaluated with a simulated femoral head, two types of cement, (low and high viscosity) and two cementing techniques: direct (cement apposition directly on the femoral head) and indirect (cement poured into the femoral component). Results High-viscosity cement showed homogeneous distribution over the entire femoral head. Low-viscosity cement showed a massive polar concentration with insufficient, if not absent, distribution in the equatorial zone. Conclusion Polar cement concentration could be a risk factor for early implant failure due to two effects on the femoral head: biological (excessive local exothermic reaction could cause osteocyte necrosis) and biomechanical (which could lead to uneven load distribution on the femoral head).

    One of the objectives of the team supporting the LDEF Systems and Materials Special Investigative Groups is to develop databases of experimental findings. These databases identify the hardware flown, summarize results and conclusions, and provide a system for acknowledging investigators, tracing sources of data, and future design suggestions. To date, databases covering the optical experiments, and thermal control materials (chromic acid anodized aluminum, silverized Teflon blankets, and paints) have been developed at Boeing. We used the Filemaker Pro software, the database manager for the Macintosh computer produced by the Claris Corporation. It is a flat, text-retrievable database that provides access to the data via an intuitive user interface, without tedious programming. Though this software is available only for the Macintosh computer at this time, copies of the databases can be saved to a format that is readable on a personal computer as well. Further, the data can be exported to more powerful relational databases, capabilities, and use of the LDEF databases and describe how to get copies of the database for your own research.

    Full Text Available The LHCf experiment has taken data in 2009 and 2010 p-p collisions at LHC at √s = 0.9 TeV and √s = 7 TeV. The measurement of the forward neutral particle spectra produced in proton-proton collisions at LHC up to an energy of 14 TeV in the center of mass system are of fundamental importance to calibrate the Monte Carlo models widely used in the high energy cosmic ray (HECR field, up to an equivalent laboratory energy of the order of 1017 eV. In this paper the first results on the inclusive photon spectrum measured by LHCf is reported. Comparison of this spectrum with the model expectations show significant discrepancies, mainly in the high energy region. In addition, perspectives for future analyses as well as the program for the next data taking period, in particular the possibility to take data in p-Pb collisions, will be discussed.

    Full Text Available Purpose: Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR brachytherapy was applied prior to definitive radiochemotherapy. Material and methods : In this single arm phase II clinical trial between 2013 to 2014 twenty patients with locally advanced esophageal cancer (17 squamous cell and 3 adenocarcinoma were treated with upfront 10 Gy HDR brachytherapy, followed by 50.4 Gy external beam radiotherapy (EBRT and concurrent chemotherapy with cisplatin/5-fluorouracil. Results : Tumor response, as measured by endoscopy and/or computed tomography scan, revealed complete remission in 16 and partial response in 4 patients (overall response rate 100%. Improvement of dysphagia was induced by brachytherapy within a few days and maintained up to the end of treatment in 80% of patients. No differences in either response rate or dysphagia resolution were found between squamous cell and adenocarcinoma histology. The grade 2 and 3 acute pancytopenia or bicytopenia reported in 4 patients, while sub-acute adverse effects with painful ulceration was seen in five patients, occurring after a median of 2 months. A perforation developed in one patient during the procedure of brachytherapy that resolved successfully with immediate surgery. Conclusions : Brachytherapy before EBRT was a safe and effective procedure to induce rapid and durable relief from dysphagia, especially when combined with EBRT.

    The Mega Ampère Spherical Tokamak (MAST) programme is strongly focused on addressing key physics issues in preparation for operation of ITER as well as providing solutions for DEMO design choices. In this regard, MAST has provided key results in understanding and optimizing H-mode confinement, operating with smaller edge localized modes (ELMs), predicting and handling plasma exhaust and tailoring auxiliary current drive. In all cases, the high-resolution diagnostic capability on MAST is complemented by sophisticated numerical modelling to facilitate a deeper understanding. Mitigation of ELMs with resonant magnetic perturbations (RMPs) with toroidal mode number nRMP = 2, 3, 4, 6 has been demonstrated: at high and low collisionality; for the first ELM following the transition to high confinement operation; during the current ramp-up; and with rotating nRMP = 3 RMPs. nRMP = 4, 6 fields cause less rotation braking whilst the power to access H-mode is less with nRMP = 4 than nRMP = 3, 6. Refuelling with gas or pellets gives plasmas with mitigated ELMs and reduced peak heat flux at the same time as achieving good confinement. A synergy exists between pellet fuelling and RMPs, since mitigated ELMs remove fewer particles. Inter-ELM instabilities observed with Doppler backscattering are consistent with gyrokinetic simulations of micro-tearing modes in the pedestal. Meanwhile, ELM precursors have been strikingly observed with beam emission spectroscopy (BES) measurements. A scan in beta at the L-H transition shows that pedestal height scales strongly with core pressure. Gyro-Bohm normalized turbulent ion heat flux (as estimated from the BES data) is observed to decrease with increasing tilt of the turbulent eddies. Fast ion redistribution by energetic particle modes depends on density, and access to a quiescent domain with ‘classical’ fast ion transport is found above a critical density. Highly efficient electron Bernstein wave current drive (1 A W-1) has been achieved

    A significant challenge to wildlife managers in tourism settings is to provide visitors with opportunities to observe rare and endangered wildlife while simultaneously protecting the target species from deleterious impacts. Nearly 100,000 people annually visit Crystal River, Florida, USA to observe and swim with the Florida manatee, an endangered species. This research aimed to investigate and describe human-manatee interactions in a tourism context, to understand the salient issues related to such interactions as identified by stakeholders, and to recommend a course of action to address multiple interests in the planning and management of human-manatee interactions. Five issues were identified by all stakeholder groups: water quality, harassment, density and crowding, education, and enforcement. Currently, the U.S. Fish and Wildlife Service, which is responsible for manatee management, does not have mechanisms in place to manage the tourism component of the manatee encounter. Although a regulatory approach can be taken, a better approach would be to create an organization of tour operators to establish “best practices” that reflect the goal of the managing agency to enhance manatee protection (and thus ensure their livelihood) and to enhance the visitor experience.

    , specifically operating in inland- waterways and roads. Safety-of-life applications for assisted vessel navigation and for management of hazardous goods (gas) transhipment over the Po river were thoroughly tested and assessed. Applications for emergency assistance, Point of Interest inquiry, localisation of commercial fleet were also proven.GAUSS successfully demonstrated integrated GNSS1 precise positioning based on EGNOS and satellite UMTS packet communication. The new technology with respect to the current state-of the art, developed within the project, was validated during the trial campaign, including the implemented broadcasting and multicasting communication of data packet compliant to 3GPP standard (current release 4). Horizontal accuracy better than 3-m was achieved in the trial area (Northern Italy - Lario - Como Lake, Parma and Po river areas), thanks to the navigation functions based on GPS signals augmented with SBAS techniques. The MTB (Mediterranean Test Bed) was utilised because of the poor performance coverage of the ESTB system over the Italian regions.In this paper, the results of the GAUSS trial campaign are reported, along with their assessment and evaluation in terms of possible enhancements and future exploitations.

    Full Text Available Rhinoplasty is one of the most challenging surgical procedures in plastic surgery. It is not surprising that a significant number of patients end up with unfavourable outcomes. Many of these unfavourable outcomes could be the result of poor judgment and wrong decision making. Most frequently, the unfavourable outcome is the result of errors in surgical technique. In this paper, unfavourable outcomes resulting from errors in surgical technique are discussed under the heading of each operative step. Poor placement of intra-nasal incision can result in internal valve obstruction. Bad columellar scars can result from errors during open rhinoplasty. Unfavourable results associated with skeletonisation are mentioned. Tip plasty, being the most difficult part of rhinoplasty, can result in lack of tip projection, asymmetry and deformities associated with placement of tip grafts. Over-resection of the lower lateral cartilages during tip plasty can also result in pinched nose, alar collapse causing external valve obstruction and other alar rim deformities. Humpectomy can result in open roof deformity, inverted V deformity and over-resection resulting in saddle nose. The so-called poly beak deformity is also a preventable unfavourable outcome when dealing with a large dorsal hump. Complications resulting from osteotomies include narrowing of nasal airway, open roof deformity, inverted V deformity and asymmetry of the bony wall resulting from incomplete or green stick fractures. Judicious use of grafts can be very rewarding. By the same token, grafts also carry with them the risk of complications. Allografts can result in recurrent infection, atrophy of the overlying skin and extrusion resulting in crippling deformities. Autografts are recommended by the author. Unfavourable results from autografts include displacement of graft, visibility of the graft edges, asymmetry, warping, and resorption.

    Csikor, Ferenc

    2000-01-01

    Recent results of four-dimensional (4d) lattice simulations on the finite temperature electroweak phase transition (EWPT) are discussed. The phase transition is of first order in the SU(2)-Higgs model below the end point Higgs mass 66.5$\\pm$1.4 GeV. For larger masses a rapid cross-over appears. This result completely agrees with the results of the dimensional reduction approach. Including the full Standard Model (SM) perturbatively the end point is at 72.1$\\pm$1.4 GeV. Combined with recent LEP Higgs mass lower bounds, this excludes any EWPT in the SM. A one-loop calculation of the static potential makes possible a precise comparison of the lattice and perturbative results. Recent 4d lattice studies of the Minimal Supersymmetric SM (MSSM) are also mentioned.

  3. PHENIX recent heavy flavor results

    Cold nuclear matter (CNM) effects provide an important ingredient to interpret the results from heavy-ion collisions. Such effects include nuclear shadowing, intrinsic parton transverse momentum broadening, and initial patron energy loss. The measurement of heavy quark production is a good probe to study the CNM effects particularly on gluons, since heavy quarks are mainly produced via gluon fusions at RHIC energy. The PHENIX experiment has an ability to study the CNM effects by measuring leptons from heavy-flavor decay in a broad kinematic range. Comparisons of the results measured in different rapidity regions allow us to study modification of gluon density function in the Au nucleus depending on parton fractional momentum x. In addition, comparisons to the results from heavy-ion collisions (Au + Au and Cu + Cu) measured by PHENIX provide an insight into the role of CNM effects in such collisions. Recent PHENIX results on heavy quark production are discussed in this presentation.

    We report an improved SIMPLE experiment comprising four superheated droplet detectors with a total exposure of 0.42 kgd. The result yields ~ factor 10 improvement in the previously-reported results, and -- despite the low exposure -- is seen to provide restrictions on the allowed phase space of spin-dependent coupling strengths almost equivalent to those from the significantly larger exposure NAIADCDMS/ZEPLIN searches.

    The European Space Agency's Planck satellite, which is dedicated to studying the early Universe and its subsequent evolution, was launched on 14 May 2009. It scanned the microwave and submillimetre sky continuously between 12 August 2009 and 23 October 2013. In February 2015, ESA and the Planck Collaboration released the second set of cosmology products based ondata from the entire Planck mission, including both temperature and polarization, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the main characteristics of the data and the data products in the release, as well as the associated cosmological and astrophysical science results and papers. The data products include maps of the cosmic microwave background (CMB), the thermal Sunyaev-Zeldovich effect, diffuse foregrounds in temperature and polarization, catalogues of compact Galactic and extragalactic sources (including separate catalogues of Sunyaev-Zeldovich clusters and Galactic cold clumps), and extensive simulations of signals and noise used in assessing uncertainties and the performance of the analysis methods. The likelihood code used to assess cosmological models against the Planck data is described, along with a CMB lensing likelihood. Scientific results include cosmological parameters derived from CMB power spectra, gravitational lensing, and cluster counts, as well as constraints on inflation, non-Gaussianity, primordial magnetic fields, dark energy, and modified gravity, and new results on low-frequency Galactic foregrounds.

The former sets up quantitative internal production targets, while the latter advocates that production is planned according to outcomes which are defined as institution......-produced effects on individuals or businesses in society; effects which are often produced by ‘nudging’ the citizenry in a certain direction. With point of departure in these two governance-systems, the paper explores a case of controversial inspection of businesses’ negative VAT accounts and it describes...... the performance measure that guides the inspectors’ inspection (or nudging) of the businesses. The analysis shows that although a result-based governance system is advocated on a strategic level, performance measures which are not ‘result-based’ are developed and used in the daily coordination of work. The paper...

    The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14 May 2009 and has been scanning the microwave and submillimetre sky continuously since 12 August 2009. In March 2013, ESA and the Planck Collaboration released the initial cosmology products based on the first 15.5 months of Planck data, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the mission and its performance, the processing, analysis, and characteristics of the data, the scientific results, and the science data products and papers in the release. The science products include maps of the cosmic microwave background (CMB) and diffuse extragalactic foregrounds, a catalogue of compact Galactic and extragalactic sources, and a list of sources detected through the Sunyaev-Zeldovich effect. The likelihood code used to assess cosmological models against the Planck data and a lensing likelihood are described. Scientific results include robust support for the standard six-parameter ΛCDM model of cosmology and improved measurements of its parameters, including a highly significant deviation from scale invariance of the primordial power spectrum. The Planck values for these parameters and others derived from them are significantly different from those previously determined. Several large-scale anomalies in the temperature distribution of the CMB, first detected by WMAP, are confirmed with higher confidence. Planck sets new limits on the number and mass of neutrinos, and has measured gravitational lensing of CMB anisotropies at greater than 25σ. Planck finds no evidence for non-Gaussianity in the CMB. Planck's results agree well with results from the measurements of baryon acoustic oscillations. Planck finds a lower Hubble constant than found in some more local measures. Some tension is also present between the amplitude of matter fluctuations (σ8) derived from

    2014-01-01

    To understand the power of distributed systems, it is necessary to understand their inherent limitations: what problems cannot be solved in particular systems, or without sufficient resources (such as time or space). This book presents key techniques for proving such impossibility results and applies them to a variety of different problems in a variety of different system models. Insights gained from these results are highlighted, aspects of a problem that make it difficult are isolated, features of an architecture that make it inadequate for solving certain problems efficiently are identified

    For several years numerical simulations have been revealing the details of general relativity's predictions for the dynamical interactions of merging black holes. I will review what has been learned of the rich phenomenology of these mergers and the resulting gravitational wave signatures. These wave forms provide a potentially observable record of the powerful astronomical events, a central target of gravitational wave astronomy. Asymmetric radiation can produce a thrust on the system which may accelerate the single black hole resulting from the merger to high relative velocity.

    This thesis consists of three papers in Diophantine approximation, a subbranch of number theory. Preceding these papers is an introduction to various aspects of Diophantine approximation and formal Laurent series over Fq and a summary of each of the three papers. The introduction introduces...... the basic concepts on which the papers build. Among other it introduces metric Diophantine approximation, Mahler’s approach on algebraic approximation, the Hausdorff measure, and properties of the formal Laurent series over Fq. The introduction ends with a discussion on Mahler’s problem when considered....... The first part is about a failed attempt of applying dynamical methods to obtain results and is not part of the paper. It explains the ideas of how the real case works and what goes wrong in the case of the formal Laurent series. The second part contains the results of the paper and sketches of the proofs....

    1979-01-01

    Results obtained at the e/sup +/e/sup -/ storage ring PETRA by the PLUTO collaboration at c.m. energies of 13, 17 and 27.4 GeV are presented. New limits on QED cut-off parameters are determined from Bhabha scattering; at 27.4 GeV the limits are Lambda /sub +/>38 GeV and Lambda /sub -/>60 GeV. The measured values of the total hadronic cross section, and the study of the jet character of the hadronic events are well consistent with the expected production of b mesons (with q/sub b/=1/3), but do not require additional new quarks with charge 2/3. Hadronic events from two-photon exchange processes are observed with comparable rates as events from one-photon exchange. First results on the hadronic cross section in gamma gamma collisions are given. (8 refs).

    Tremendous progress has been made in mapping out the spectrum of hadrons over the past decade with plans to make further advances in the decade ahead. Baryons and mesons, both expected and unexpected, have been found, the results of precision experiments often with polarized beams, polarized targets and sometimes polarization of the final states. All these hadrons generate poles in the complex energy plane that are consequences of strong coupling QCD. They reveal how this works.

    Full Text Available The article identifies essence of the “audit result” and “users of audit result” notions and characteristics of the key audit results user. It shows that in order to give a wide characteristic of users it is expedient to unite all objects, which could be used (audit report, fact of refusal to conduct audit and information that is submitted to managers in the process of audit with the term “audit result” and classify it depending on the terms of submission by final and intermediate result. The article offers to define audit results user as a person, persons or category of persons for whom the auditor prepares the audit report and, in cases, envisaged by international standards of the audit and domestic legislative and regulatory acts, provides other additional information concerning audit issues. In order to identify the key audit results user the article distributes all audit tasks into two groups depending on possibilities of identification of users. The article proves that the key user should be identified especially in cases of a mandatory audit and this process should go in interconnection with the mechanism of allocation of a key user of financial reports. It offers to consider external users with direct financial interests, who cannot request economic subjects directly to provide information and who should rely on general financial reports and audit report when receiving significant portion of information they need, as the key user. The article makes proposals on specification of the categorical mechanism in the sphere of audit, which are the basis for audit quality assessment, identification of possibilities and conditions of appearance of the necessary and sufficient trust to the auditor opinion.

    Full Text Available Introduction: Final results evaluation after rhinoplasty is a not a topic widely studied from the patient's viewpoint. Objective:Evaluate the satisfaction of the patients submitted to reduction rhinoplasty, from the questionnaire Rhinoplasty Outcomes Evaluation (ROE. Method: Longitudinal study, retrospective cut type, of the preoperative and postoperative satisfaction. The sample was composed by 28 patients who were submitted to rhinoplasty and answered the ROE questionnaire. Three variables were obtained: satisfaction note that the patient had with his/her image before the surgery; note of satisfaction with the current appearance; the difference of the average satisfaction notes between postoperative and preoperative approaches. Results: The postoperative note was higher than the preoperative in all patients. We noticed a difference between the average of the postoperative and preoperative of 48.3 (p75 considered to be an excellent outcome (67.9%. Conclusions: The ROE questionnaire is a helpful tool to show the satisfaction of the patient submitted to reduction rhinoplasty. About 92% of the patients submitted to reduction rhinoplasty consider the postoperative result to be good or excellent.

    The Daya Bay reactor neutrino experiment observed electron antineutrino disappearance associated with $\\theta_{13}$ with a significance better than $5\\sigma$ in 2012. The final two of eight antineutrino detectors were installed in the summer of 2012. Including the 404 days of data collected with the full detector configuration resulted in a 3.6 times increase of statistics over the previous result with the 6-AD configuration. With improvements of the systematic uncertainties and better estimation of backgrounds, Daya Bay has measured $\\sin^22\\theta_{13} = 0.084\\pm0.005$ and $|\\Delta m^2_{ee}|=2.42^{+0.10}_{-0.11}\\times 10^{-3}$~eV$^2$. This is the most precise measurement of $\\sin^22\\theta_{13}$ to date and the most precise measurement of of $|\\Delta m^2_{ee}|$ via electron antineutrino disappearance. Several other analysis results are presented, including an independent measurement of $\\theta_{13}$ using inverse-beta decays associated with neutron capture on hydrogen, a measurement of reactor antineutrino fl...

    The European Space Agency's Planck satellite, dedicated to studying the early Universe and its subsequent evolution, was launched 14~May 2009 and scanned the microwave and submillimetre sky continuously between 12~August 2009 and 23~October 2013. In February~2015, ESA and the Planck Collaboration released the second set of cosmology products based on data from the entire Planck mission, including both temperature and polarization, along with a set of scientific and technical papers and a web-based explanatory supplement. This paper gives an overview of the main characteristics of the data and the data products in the release, as well as the associated cosmological and astrophysical science results and papers. The science products include maps of the cosmic microwave background (CMB), the thermal Sunyaev-Zeldovich effect, and diffuse foregrounds in temperature and polarization, catalogues of compact Galactic and extragalactic sources (including separate catalogues of Sunyaev-Zeldovich clusters and Galactic col...

  7. Results from IceCube

    2016-01-01

    Full Text Available Data from the IceCube Neutrino Observatory have revealed the existence of a flux of high energy neutrinos of extraterrestrial origin, which is observed in a number of analyses spanning different energy ranges, fields of view, and neutrino flavors. The current data are consistent with an isotropic, equal-flavor flux described by a simple power law spectrum, but deviations from this simple model cannot yet be constrained with high precision. The existing observations in this area are reviewed, along with recent results on dark matter searches and observations of cosmic rays.

    The ALICE experiment explores the properties of strongly interacting QCD matter at extremely high temperatures created in Pb-Pb collisions at LHC and provides further insight into small-system physics in (high-multiplicity) pp and p-Pb collisions. The ALICE collaboration presented 27 parallel talks, 50 posters, and 1 flash talk at Quark Matter 2015 and covered various topics including collective dynamics, correlations and fluctuations, heavy flavors, quarkonia, jets and high $p_{\\rm T}$ hadrons, electromagnetic probes, small system physics, and the upgrade program. This paper highlights some of the selected results.

  9. Recent QCD results from ATLAS

    CERN Document Server

    Meyer, C; The ATLAS collaboration

    2014-01-01

    The ATLAS collaboration has performed studies of a wide range of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-QCD measurements include studies of underlying event and vector meson production. Differential measurements of inclusive and dijet production provide stringent tests of high-order QCD predictions and provide input for determination of parton density functions. Measurements of isolated inclusive and di-photons cross sections for high transverse momentum photons test theoretical predictions of perturbative QCD and constrain parton density functions. An overview of these results is given.

    CERN Document Server

    Lucchesi, Donatella

    2016-01-01

    Measurements of electroweak bosons production provide an important test of the Standard Model at the LHC energies and allow the partonic content of the proton to be constrained. The LHCb forward acceptance is suited for measurements complementary to the other LHC experiments. W and Z bosons are reconstructed in e and μ leptonic final states using data samples collected at energies in the center of mass frame of √ s = 7 , 8 , 13 TeV corresponding to integrated luminosities of 1 , 2 , 0 . 29 fb − 1 respectively. Results on W + b / c quark and on W / Z + jets are also presented.

  11. RSG Deployment Case Testing Results

    Owsley, Stanley L.; Dodson, Michael G.; Hatchell, Brian K.; Seim, Thomas A.; Alexander, David L.; Hawthorne, Woodrow T.

    2005-09-01

    The RSG deployment case design is centered on taking the RSG system and producing a transport case that houses the RSG in a safe and controlled manner for transport. The transport case was driven by two conflicting constraints, first that the case be as light as possible, and second that it meet a stringent list of Military Specified requirements. The design team worked to extract every bit of weight from the design while striving to meet the rigorous Mil-Spec constraints. In the end compromises were made primarily on the specification side to control the overall weight of the transport case. This report outlines the case testing results.

    Kajita, Takaaki

    2000-05-01

    Results from Super-Kamiokande on atmospheric neutrinos and solar neutrinos are presented. The atmospheric neutrino data exhibited a zenith angle dependent deficit of muon neutrinos. Experimental biases and uncertainties in the prediction were unable to explain the data. However, the data were in good agreement with two flavor {nu}{sub {mu}} {r_reversible} {nu}{sub {tau}} oscillations. The solar neutrino data showed a deficit of the neutrinos. The day-night effect and the energy spectrum of recoil electrons were studied.

    2004-01-01

    We briefly review some of the recent AMANDA results emphasizing the all flavor capabilities of the high energy neutrino telescope, important in the context of equal neutrino mixing from distant sources at Earth. Together with a report on a preliminary UHE neutrino flux limit, the course of our progress in the quest for point sources is described. Finally, a 1 year preliminary limit of AMANDA-II to neutralino cold dark matter (CDM) candidates, annihilating in the center of the Sun, for various MSSM parameter choices is presented and discussed.

    2012-01-01

    Howard’s algorithm is a fifty-year old generally applicable algorithm for sequential decision making in face of uncertainty. It is routinely used in practice in numerous application areas that are so important that they usually go by their acronyms, e.g., OR, AI, and CAV. While Howard’s algorithm...... is generally recognized as fast in practice, until recently, its worst case time complexity was poorly understood. However, a surge of results since 2009 has led us to a much more satisfactory understanding of the worst case time complexity of the algorithm in the various settings in which it applies...

    Bohnhoff-Hlavacek, Gail

    1993-01-01

    The Long Duration Exposure Facility (LDEF) carried 57 experiments and 10,000 specimens for some 200 LDEF experiment investigators. The external surface of LDEF had a large variety of materials exposed to the space environment which were tested preflight, during flight, and post flight. Thermal blankets, optical materials, thermal control paints, aluminum, and composites are among the materials flown. The investigations have produced an abundance of analysis results. One of the responsibilities of the Boeing Support Contract, Materials and Systems Special Investigation Group, is to collate and compile that information into an organized fashion. The databases developed at Boeing to accomplish this task is described.

    2016-01-01

    While Standard Model is in a good shape especially after Higgs boson discovery, there are a lot of questions beyond SM. The ATLAS detector is performing about 50 Exotics searches addressed these questions. This talk is discussing some of them with datasets collected during the 2015-2016 LHC run from 3 fb^-1 to 18 fb^-1 of proton-proton collisions at 13 TeV centre of mass energy . Results on searches for resonances decaying into vector boson or fermions, for vector like quarks, for dark matter, and for other new phenomena using these data will be presented.

  2. Unfavourable results following reduction mammoplasty

    Full Text Available Breast reduction is a common cosmetic surgical procedure. It aims not only at bringing down the size of the breast proportionate to the build of the individual, but also to overcome the discomfort caused by massive, ill-shaped and hanging breasts. The operative procedure has evolved from mere reduction of breast mass to enhanced aesthetic appeal with a minimum of scar load. The selection of technique needs to be individualised. Bilateral breast reduction is done most often. Haematoma, seroma, fat necrosis, skin loss, nipple loss and unsightly, painful scars can be the complications of any procedure on the breast. These may result from errors in judgement, wrong surgical plan and imprecise execution of the plan. Though a surfeit of studies are available on breast reduction, very few dwell upon its complications. The following article is a distillation of three decades of experience of the senior author (L.S. in reduction mammoplasty. An effort is made to understand the reasons for unfavourable results. To conclude, most complications can be overcome with proper selection of procedure for the given patient and with gentle tissue handling.

  3. Heel pain--operative results.

    Science.gov (United States)

    Baxter, D E; Thigpen, C M

    1984-01-01

    In 6 years through 1982, the authors performed 34 operative cases in 26 patients with recalcitrant heel pain. The operative procedure involves an isolated neurolysis of the mixed nerve supplying the abductor digiti quinti muscle as it passes beneath the abductor hallucis muscle and beneath the medial ridge of the calcaneus. The deep fascia of the abductor hallucis muscle is released routinely, and an impinging heel spur or tight plantar fascia is partially removed or released if it is causing entrapment of the nerve. The biomechanical pathogenesis of heel pain in relation to pes planus and pes cavus predisposing to an entrapment neuropathy is described, and the anatomy of the heel in relation to the nerve distribution is clarified and well illustrated. Of the 34 operated heels, 32 had good results and two had poor results. Heel pain can cause total disability in the working population and may jeopardize one's employment or professional athletic career. The authors believe operative treatment has a place in the care of recalcitrant heel pain and that an entrapment neuropathy is an etiological factor in heel pain.

  4. Unfavourable results in thumb reconstruction

    2013-01-01

    The history of thumb reconstruction parallels the history of hand surgery. The attributes that make the thumb unique, and that the reconstructive surgeon must assess and try to restore when reconstructing a thumb, are: Position, stability, strength, length, motion, sensibility and appearance. Deficiency in any of these attributes can reduce the utility of the reconstructed thumb. A detailed assessment of the patient and his requirements needs to be performed before embarking on a thumb reconstruction. Most unsatisfactory results can be attributed to wrong choice of procedure. Component defects of the thumb are commonly treated by tissue from adjacent fingers, hand or forearm. With refinements in microsurgery, the foot has become a major source of tissue for component replacement in the thumb. Bone lengthening, osteoplastic reconstruction, pollicisation, and toe to hand transfers are the commonest methods of thumb reconstruction. Unfavourable results can be classified as functional and aesthetic. Some are common to all types of procedures. However each type of reconstruction has its own unique set of problems. Meticulous planning and execution is essential to give an aesthetic and functionally useful thumb. Secondary surgeries like tendon transfers, bone grafting, debulking, arthrodesis, may be required to correct deficiencies in the reconstruction. Attention needs to be paid to the donor site as well.

    2010-01-01

    We developed a method to make GEM foils with a spherical geometry. Tests of this procedure and with the resulting spherical GEMs are presented. Together with a spherical drift electrode, a spherical conversion gap can be formed. This eliminates the parallax error for detection of x-rays, neutrons or UV photons when a gaseous converter is used. This parallax error limits the spatial resolution at wide scattering angles. Besides spherical GEMs, we have developed curved spacers to maintain accurate spacing, and a conical field cage to prevent edge distortion of the radial drift field up to the limit of the angular acceptance of the detector. With these components first tests are done in a setup with a spherical entrance window but a planar readout structure; results will be presented and discussed. A flat readout structure poses difficulties, however. Therefore we will show advanced plans to make a prototype of an entirely spherical double-GEM detector, including a spherical 2D readout structure. This detector w...

    Full Text Available Forty cases of Austin Moore Replacement done for transcervical fractures of the femur in patients were reviewed after a period of 12 to 48 months postoperatively (mean 26 mth. 30 cases (75% had mild to severe pain of non-infective origin, starting as early as 6 months postoperatively. This was irrespective of the make, size or position (varus/valgus of the prosthesis. Though the Aufranc and Sweet clinical scoring was satisfactory in 65% cases, radiological evidence of complications like sinking, protrusion, etc. were seen in majority of the cases. Calcar resorption was seen in 34 cases (85% as early as 4 months postoperatively. Results of THR and bipolar replacement done for transcervical fractures in recent literature show 85% pain-free cases at 5 years. We feel that Austin Moore Replacement should be reserved for patients more than 65 years of age and those who are less active or debilitated because of other factors, because of increased acetabular wear with time in the younger individual. This is corroborated by unsatisfactory results in patients less than 65 years of age (p < 0.05.

    Full Text Available Aim: Valve diseases in developing countries like Turkey which often occur as a complication of rheumatic fever are a serious disease. Surgical treatment of valve diseases should be done before irreversible damage to the myocardium occurred. In this study, we aimed to present the early results of mechanical valve replacement operations. Method: A hundred patients with mechanical valve replacement surgery were retrospectively evaluated in Seyhan Application Center attached to our clinic between July 2007 and August 2011. Results: Fifty patients were male and 50 were women. The mean age of patients was 47.88 (18-78. Isolated aortic valve replacement (AVR was performed to 23 patients, isolated mitral valve replacement (MVR was 32, double valve replacement (AVR + MVR was 12, MVR + aortic valve valvuloplasty was 1, AVR + mitral kommissurotomi was 1, AVR + coronary artery bypass graft surgery (CABG was 17, MVR + CABG was 8, MVR + atrial septal defect closure was 2 and Bentall procedure.was 4 patients. In addition, ablation procedure was performed to 5 patients intraoperatively because of preoperative atrial fibrillation. Two patients (2 % died in early postoperative period. Conclusion: Mechanical prosthetic valves are used for surgical treatment of valve disease with low mortality and morbidity in a large group of patients like women that not to think to get pregnant, non advanced age group and patients have less risky for anticoagulation drug in our clinic.

    Radial head replacement is frequently used in treatment of radial head fractures or sequela. Impossibility to restore a correct anatomy, acute elbow traumatic instability and failure of osteosynthesis hardware are the most common indications. The authors describe their case studies and results on the implantation of various radial head prostheses. Between June 2005 and June 2016, 28 radial head prostheses were implanted in the same number of patients with an average follow-up of 49 months (6-104). Indications for implantation were: Mason type III and IV radial head fractures and post-traumatic arthritis due to failure of previous treatments. Monopolar prostheses were used and were press-fit implanted via Kaplan's lateral access and Kocher's anconeus approach to the humeroradial joint. At the follow-up, assessments were made of the pain, according to the visual analogic scale, range of motion (ROM), stability and functionality according to the Mayo Elbow Performance Score, presence of osteolysis and mobilization during radiography tests, personal satisfaction of the patients, Disabilities of the Arm, Shoulder and Hand and Patient-Rated Wrist Evaluation outcomes measurements. At the follow-up, we recorded an average level of pain of 1.8 in patients under acute treatments for radial head fractures and a marked reduction in the remaining cases from 6.7 to 2.1. ROM was found on average to be 107° of flexion-extension and 159° of pronosupination. Personal satisfaction was good-excellent in 23 cases. There was no case of infection; removal of the implant was necessary in three cases due to mobilization of the stem and oversized implants. In six cases, bone resorption was seen at the level of the prosthetic collar and it was in all cases asymptomatic. The results of this study suggest that the use of prostheses, if well positioned, is a valid solution in the treatment of secondary arthritis and fractures of the radial head with poor prognosis, with good results in the

    Lead nucleus collisions in the LHC recreate the state of matter which existed when the universe was a few microseconds old. This super-hot matter, composed of quark and gluons, emits thousands of particles as it expands, cools and converts back into hadrons. The ATLAS detector provides an excellent opportunity to perform detailed studies of this novel state of matter, measuring its bulk properties and its response to penetrating probes. Recent studies of particle correlations and fluctuations shed light on the initial geometry and its evolution into the final state. Studies of jet suppression and fragmentation show how the energetic partons interact with the medium. High precision measurements of boson production and first results on boson-jet correlations are important steps towards quantitative understanding of the parton energy loss mechanism.

    2014-01-01

    The ATLAS collaboration has performed studies of a wide range of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-QCD measurements include studies of underlying event, vector meson production and quark confinement effects. Differential measurements of inclusive and multi-jet production provide stringent tests of high-order QCD predictions and provide input for determination of parton density functions. Measurements of isolated inclusive and di-photons cross sections for high p_T photons test various theoretical predictions and constrain parton density functions. In addition the total p-p cross section at 7 TeV, together with the elastic and inelastic contributions, is measured and compared to various models. An overview of these results is given.

    The ATLAS collaboration has performed studies of a wide range of QCD phenomena. Recent soft-QCD measurements include studies of underlying event, hadronic event shapes, double parton scattering, diffraction, internal jet structure, jet shapes for heavy quark jets and forward energy flow. Differential measurements of inclusive and dijet production provide stringent tests of higher order QCD predictions and provide input for determination of parton density functions. Inclusive jet multiplicity ratios are sensitive to the strong coupling constant alpha_S. Measurements of the inclusive prompt isolated photon and diphoton cross sections provide a direct probe of short-distance physics. The results are compared to various theoretical models and next-to-leading-order or higher-order QCD calculations.

    The Antarctic Muon And Neutrino Detector Array (AMANDA) is a high- energy neutrino telescope based at the geographic south pole. It is a lattice of photomultiplier tubes buried deep in the polar ice, which is used as interaction and detection medium. The primary goal of this detector is the observation of astronomical sources of high-energy neutrinos. This paper shows the latest results of the search for a diffuse flux of extraterrestrial nu /sub mu /s with energies between 10/sup 11/ eV and 10/sup 18/ eV, nu /sub mu /s emitted from point sources and nu /sub mu /s from dark matter annihilation in the Earth and the Sun.

    The KASCADE-Grande experiment, located at Karlsruhe Institute of Technology (Germany) is a multi-component extensive air-shower experiment devoted to the study of cosmic rays and their interactions at primary energies 10{sup 14}-10{sup 18} eV. Main goals of the experiment are the measurement of the all-particle energy spectrum and mass composition in the 10{sup 16}-10{sup 18} eV range by sampling charged (N{sub ch}) and muon (N{sub {mu}}) components of the air shower. The method to derive the energy spectrum and its uncertainties, as well as the implications of the obtained result, is discussed. An overview of the analyses performed by KASCADE-Grande to derive the mass composition of the measured high-energy comic rays is presented as well.

    GRAVITY acquisition camera implements four optical functions to track multiple beams of Very Large Telescope Interferometer (VLTI): a) pupil tracker: a 2×2 lenslet images four pupil reference lasers mounted on the spiders of telescope secondary mirror; b) field tracker: images science object; c) pupil imager: reimages telescope pupil; d) aberration tracker: images a Shack-Hartmann. The estimation of beam stabilization parameters from the acquisition camera detector image is carried out, for every 0.7 s, with a dedicated data reduction software. The measured parameters are used in: a) alignment of GRAVITY with the VLTI; b) active pupil and field stabilization; c) defocus correction and engineering purposes. The instrument is now successfully operational on-sky in closed loop. The relevant data reduction and on-sky characterization results are reported.

    We present a selection of results based on data taken in 1997 with the 302-PMT Antarctic Muon and Neutrino Detector Array-B10 ("AMANDA-B10") array. Atmospheric neutrinos created in the northern hemisphere are observed indirectly through their charged current interactions which produce relativistic, Cherenkov-light-emitting upgoing muons in the South Pole ice cap. The reconstructed angular distribution of these events is in good agreement with expectation and demonstrates the viability of this ice-based device as a neutrino telescope. Studies of nearly vertical upgoing muons limit the available parameter space for WIMP dark matter under the assumption that WIMPS are trapped in the earth's gravitational potential well and annihilate with one another near the earth's center.

  18. Explanations for Skyline Query Results

    DEFF Research Database (Denmark)

    Chester, Sean; Assent, Ira

    2015-01-01

    Skyline queries are a well-studied problem for multidimensional data, wherein points are returned to the user iff no other point is preferable across all attributes. This leaves only the points most likely to appeal to an arbitrary user. However, some dominated points may still be interesting......, and the skyline offers little support for helping the user understand why some interesting points are omitted from the results. In this paper, we introduce the Sky-not query. Given a query point p, a dataset S, and constraints with bounding corners qL and qU, the Sky-not query returns the alternative constraints...... processed by a Sky-not query, independent of any algorithm. We then offer a skyline-like and an efficient recursive algorithm for solving Sky-not queries, which we evaluate in an extensive experimental evaluation....

  19. Azimuthal Anisotropy Results from STAR

    Energy Technology Data Exchange (ETDEWEB)

    Cebra, Daniel

    2013-05-02

    Recent advances in the studies of eventwise azimuthal anisotropy from STAR have been made possible by the high statistics 200 GeV Au + Au datasets taken in 2010 and by the broad range of energies recorded during the first phase of the RHIC beam energy scan. The high statistics full energy Au + Au data have allowed precision studies of flow. These include detailed studies of flow versus non-flow, results of elliptic flow at high p{sub T}, the ν{sub 2} contributions from jets, and elliptic flow of multi-strange hadrons. Data from the beam energy scan enables STAR to search for evidence of the first order phase transition and the onset of deconfinement through the energy systematics of directed flow, elliptic flow, and azimuthally sensitive HBT.

    "Cassini At Saturn - Huygens Results" will bring the story of the Cassini-Huygens mission and their joint exploration of the Saturnian system right up to date. Cassini is due to enter orbit around Saturn on the 1 July 2004 and the author will have 8 months of scientific data available for review, including the most spectacular images of Saturn, its rings and satellites ever obtained by a space mission. As the Cassini spacecraft approached its destination in spring 2004, the quality of the images already being returned by the spacecraft clearly demonstrate the spectacular nature of the close-range views that will be obtained. The book will contain a 16-page colour section, comprising a carefully chosen selection of the most stunning images to be released during the spacecraft's initial period of operation. The Huygens craft will be released by Cassini in December 2004 and is due to parachute through the clouds of Saturn's largest moon, Titan, in January 2005.

  1. Preliminary results of UCN τ

    Pattie, Robert; UCNtau Collaboration

    2017-01-01

    There is currently a 4 σ discrepancy between measurements of the neutron lifetime performed using cold neutron beams and those performed with ultracold neutron (UCN) storage vessels. The UCN τ experiment uses an asymmetric magneto-gravitational UCN trap with in situ counting of surviving neutrons to measure the neutron lifetime. This design eliminates a major systematic of previous bottle experiments related to the loss of UCN on material trap walls and with unloading neutrons from the storage vessel. A new in situ detection system was used in the 2015-2016 run that was able to measure the population of surviving UCN at different heights in the trap, providing important information on spectral evolution. Understanding the behavior of quasi-bound UCN in a bottle experiment is essential to achieving a subsecond precision measurement of τn. We will present the preliminary results from the 2015-2016 data set and an update on the UCN τ experiment.

    We present results from the CERN Axion Solar Telescope (CAST) and the Axion Dark Matter eXperiment (ADMX), together with a brief review on prospects on Axion searches with a variety of experimental techniques. CAST has explored masses up to 0.64 eV setting the most stringent limit on the axion-photon coupling, apart for the micro-eV region where ADMX is the most competitive experiment. CAST is aiming at surpassing the 1eV WMAP upper limit and possibly revisiting the operation in vacuum with extra sensitive X-ray detectors, while ADMX, using improved extra sensitive SQUID amplifiers will explore the micro-eV mass range.

In this study, we look for any deviations that there might be from the Standard Model, and the results are used to set limits on the Anomalous Quartic Gauge Couplings. We also report a measurement of the exclusive production of pairs of charged pions in proton-proton collisions. The differential cross sections for $\\pi^{+}\\pi^{-}$ pairs as a function of the pion pair invariant mass is measured and compared to several phenomenological predictions.

    Information regarding pelvic fractures sustained during snowboarding is scant. To analyze the epidemiologic data, injury patterns, and types of pelvic fractures sustained during snowboarding. Case series; Level of evidence, 4. We analyzed the epidemiologic factors, injury patterns, and types of pelvic fractures in 145 patients with snowboarding-related pelvic fractures who were admitted to our institution from the 1998-1999 to the 2006-2007 ski season. The incidence of snowboarding-related pelvic fractures was 0.102 per 10 000 ski lift tickets, which amounted to 2% of all snowboarding-related fractures (fifth most common type of fracture among all snowboarding-related fractures). Of the pelvic fractures, 85.5% were stable (type A according to the Tile classification) and 14.5% were unstable (types B and C according to the Tile classification). Isolated sacral fractures had the second-highest incidence (24.1%) after pubic bone and/or ischium fractures (46.9%). A distinct female prevalence was seen (52.4%). Jumps and isolated falls were the main mechanisms of injury (80%), and the incidence of collision was significantly higher in the unstable group than in the stable group (P = .037). In all, 57.9% patients classified their skill level as "intermediate," and only 9.7% of patients had received professional snowboarding lessons. A total of 30 subjects (20.8%) had other injuries along with pelvic fractures; the patients with multiple injuries were significantly more frequent in the unstable group than in the stable group (P = .035). Pelvic fractures resulting from snowboarding accidents included a higher proportion with isolated sacral fractures in the stable group and a lower prevalence of associated injuries in the unstable group compared with those resulting from other causes.

  6. CMS results in Electroweak Physics

    2011-01-01

    We present the results of electroweak studies performed using data collected in 2010 at a center-of-mass energy of 7 TeV by the CMS experiment at the LHC. Besides their intrinsic interest as unique samples to calibrate and understand the CMS detector response to leptons, jets and missing energy, events containing W and Z bosons appear as dominant components in many Higgs seaches and in most of the searches beyond the Standard Model, either as signal or as background. In addition, the excellent level of theoretical and experimental understanding of these processes allows electroweak tests at the LHC at an unprecendented level of precision. CMS uses a wide range of final states to measure cross sections, asymmetries, polarizations and differential distributions in general. The current integrated luminosity is already sufficient to perform not just inclusive measurements using W and Z decays into muons and electrons, but also precise studies of associated jet production and final states containing taus, as well...

    For many years, the petroleum industry has been developing a valve that input less shear to the flow for a given required pressure drop and this can be done using the cyclonic concept. This paper presents a comparison between the performances of a cyclonic valve (low shear) and a conventional globe valve. The aim of this work is to show the advantages of using a cyclonic low shear valve instead of the commonly used in the primary separation process by PETROBRAS. Tests were performed at PETROBRAS Experimental Center (NUEX) in Aracaju/SE varying some parameters: water cut; pressure loss (from 4 kgf/cm2 to 10 kgf/cm2); flow rates (30 m3/h and 45 m3/h). Results indicates a better performance of the cyclonic valve, if compared with a conventional one, and also that the difference of the performance, is a function of several parameters (emulsion stability, water content free, and oil properties). The cyclonic valve tested can be applied as a choke valve, as a valve between separation stages (for pressure drop), or for controlling the level of vessels. We must emphasize the importance to avoid the high shear imposed by conventional valves, because once the emulsion is created, it becomes more difficult to break it. New tests are being planned to occur in 2012, but PETROBRAS is also analyzing real cases where the applications could increase the primary process efficiency. In the same way, the future installations are also being designed considering the cyclonic valve usage. (author)

  10. XENON100 - Results and Prospects

    The XENON100 Dark Matter experiment, installed in the Laboratory Nazionali del Gran Sasso (LNGS, Italy), is searching for WIMP type Dark Matter particles scattering off a 62 kg liquid xenon target in a dual phase (liquid/gas) time projection chamber. Careful material selection, a novel detector design, and an upgrade of the passive shield, together with capitalizing the self-shielding power of liquid xenon, are crucial in order to achieve a background of less than 0.01 events kg{sup -1} keV{sup -1} day{sup -1} in the fiducial volume. This background, which has been verified experimentally, is lower than in any other dark matter experiment. The analysis of 11.2 live days of background data taken during a commissioning run in fall 2009 leads to the first science result of XENON100: No events are observed in a pre-defined fiducial volume of 40 kg mass, excluding spin-independent WIMP-nucleon scattering cross sections above 3.4 x 10{sup -44} cm{sup 2} (at 100 GeV/c{sup 2}). Below 80 GeV/c{sup 2} this is the most sensitive exclusion limit so far, disfavouring the interpretation of DAMA and CoGeNT being due to spin-independent, elastic interactions of light mass WIMPs.

  11. Uncertainty of dustfall monitoring results

    Directory of Open Access Journals (Sweden)

    Martin A. van Nierop

    2017-06-01

    Full Text Available Fugitive dust has the ability to cause a nuisance and pollute the ambient environment, particularly from human activities including construction and industrial sites and mining operations. As such, dustfall monitoring has occurred for many decades in South Africa; little has been published on the repeatability, uncertainty, accuracy and precision of dustfall monitoring. Repeatability assesses the consistency associated with the results of a particular measurement under the same conditions; the consistency of the laboratory is assessed to determine the uncertainty associated with dustfall monitoring conducted by the laboratory. The aim of this study was to improve the understanding of the uncertainty in dustfall monitoring; thereby improving the confidence in dustfall monitoring. Uncertainty of dustfall monitoring was assessed through a 12-month study of 12 sites that were located on the boundary of the study area. Each site contained a directional dustfall sampler, which was modified by removing the rotating lid, with four buckets (A, B, C and D installed. Having four buckets on one stand allows for each bucket to be exposed to the same conditions, for the same period of time; therefore, should have equal amounts of dust deposited in these buckets. The difference in the weight (mg of the dust recorded from each bucket at each respective site was determined using the American Society for Testing and Materials method D1739 (ASTM D1739. The variability of the dust would provide the confidence level of dustfall monitoring when reporting to clients.

  12. First photometry results from Gaia

    Science.gov (United States)

    Brown, Anthony

    2015-08-01

    An overview of the Gaia Photometric Processing is presented. The Gaia photometry consists of the white light (330-1050 nm) G-band, and low resolution spectrophotometry realized by two prisms dispersing all the light entering the field of view. One disperser - called BP for Blue Photometer- operates in the wavelength range 330-680 nm; the other - called RP for Red Photometer - covers the wavelength range 640-1050 nm. The light collected by BP and RP can also be integrated into two broad bands, G_BP and G_RP.This photometric data reduction is based on the overall principle of a self-calibrating system improved by iteration. The input data includes flux (G, G_BP, G_RP) and the low-resolution spectral data. The calibration models and algorithms used are described. Initial validation results are shown which indicate the photometric quality of the preliminary calibrated data. Expectations for the quality of the photometric data to be included in the first public data release (mid-2016) are discussed.

An electron between 36 and 60 MeV is identified by Cherenkov and scintillation light from {nu}{sub e}p{yields}e{sup +}n, and if a {gamma} is tightly constrained to be correlated with it from np{yields}d{gamma} (2.2 MeV), then 22 such events are observed, but only 4.6{+-}0.6 are expected from background. The probability that this is a fluctuation is <10{sup -7}. If subsequent analysis shows a similar effect from the independent channel {nu}{sub {mu}}{yields}{nu}{sub e}, then this would imply a neutrino mass difference which would contribute significantly to the dark matter of the universe. Explaining also the solar and atmospheric neutrino deficits results in a neutrino mass pattern which gives a cold + hot dark matter which fits the structure of the universe on all scales and requires a critical density universe and an universe age compatible with that of the oldest stars. This mass pattern involves a sterile neutrino, evidence for which may come from the need for it in producing heavy elements by supernovae and for blowing off the supernova mantle.

    SOFIA, the Stratospheric Observatory for Infrared Astronomy, is an airborne observatory with a 2.7-m telescope that is under development by NASA and the German Aerospace Center DLR. From late 2010 and through the end of 2011, SOFIA conducted a series of science demonstration flights, Early Science, using FORCAST (the Faint Object InfraRed Camera for the SOFIA Telescope), HIPO (the High-speed Imaging Photometer for Occultations), and GREAT (the German REceiver for Astronomy at Terahertz frequencies). Flying at altitudes as high as 13.7 km (45,000 ft), SOFIA operates above more than 99.8% of the water vapor in the Earth’s atmosphere, opening up most of the far-infrared and sub-millimeter parts of the spectrum. During Early Science, 30 science missions were flown with results in solar system astronomy, star formation, the interstellar medium, the Galactic Center, and extragalactic studies. Many of these investigations were conducted by the first group of SOFIA General Investigators, demonstrating the operation of SOFIA as a facility for the astronomical community. This paper presents some recent highlights from Early Science.

    Association du personnel

    The elections to renew the Staff Council for the 2010-2011 period are now behind us and we are very pleased to have had at least as many candidates as posts in five of the six electoral colleges. Furthermore, the average rate of participation of 56.8% in these elections is a very good result compared to previous years. We thank the candidates who have committed themselves to actively defending the interests of the staff, and all our members have shown, by voting, their full support of the candidates in their college and Department. This newly-elected Staff Council (see its composition on the following page) will therefore be truly representative of all the sectors and professions of the Organization, which will be a major asset when the Staff Association representatives begin discussions with the Management and Member States in 2010 on the key issues of the five-yearly review and the measures to be taken to absorb the deficit of our Pension Fund. Armed with this vote of confidence, we know that we can count o...

    Historically, cervical cancer in early stages has been treated with radical hysterectomy and radiotherapy with no option in keeping the uterine-ovarian function. Since two decades ago, evidence shows these cases are candidates for radical trachelectomy, a procedure capable of preserving the fertility without affecting the oncological outcome. To analyze reproductive results among patients treated with radical trachelectomy, in a reference center from the northeast of Mexico. Between March 1999 and December 2013, 27 cases with cervical cancer in early stages were treated with vaginal or abdominal radical trachelectomy in the ISSSTE Regional Hospital in Monterrey, NL (Mexico). We obtained the gynecological, medical and surgical clinical history. Plan of analysis consisted of descriptive statistics. Age range was 27-39 years. Main complications were cervical stenosis (n=1) and erosion of cerclaje (n=2). Eighteen patients tried to get pregnant, 8 of them got a spontaneous pregnancy; 1 more patient required assisted reproduction technics and did not succeed. All pregnancies were delivered by cesarean section and were preterm births; 3 underwent premature rupture of membranes. Two pregnancies ended in abortion, one at 10 weeks with severe hemorrhage that needed hysterectomy; the second one, at 1 7 weeks, received a fine uterine curettage. Only 6 cases (33%) got a live birth. Only one third of the attempted pregnancies got a live birth. Assisted reproduction technics play an important role and should be offer to all cases. Cerclaje is an important factor to carry a pregnancy up to the third trimester.

    The PHENIX experiment at the Relativistic Heavy Ion Collider explores the spin structure of the proton in polarized p+p collisions at center-of-mass energies up to 500 GeV. Tremendous experimental and theoretical progress has been made toward understanding the physics involved with transversely polarized beams or targets in recent years. Not only nucleon structure and parton distribution functions but also QCD dynamics have been studied in various physics processes in high-energy polarized DIS and p+p collisions. In the 2006 and 2008 RHIC runs, the PHENIX experiment took a significant amount of transversely polarized p+p collision data at 200 GeV center-of-mass energy, with an integrated luminosity of 8 $pb^{-1}$ and beam polarizations up to 50%. Single spin asymmetries of different probes have been measured in mid- and forward-rapidities. In this report, we present the latest transverse spin results from the PHENIX experiment and discuss briefly the prospects of future transverse spin physics with the PHENIX...

    The purpose of this study was to compare the integrated EMG activity of spastic muscles in brain-damaged patients before and during splint application. Eight patients with spasticity that produced limb posturing were systematically monitored for EMG activity during a two-hour interval without a splint (Nonsplinted Condition), and during a subsequent two-hour period while wearing the splint (Splinted Condition). The goniometric measurement of the limb position also was taken during the two conditions. The limb postures monitored were ankle plantar flexion, wrist flexion, and elbow flexion. A paired t test showed a significant (p less than .001) increase in the position of the limb into extension in the Splinted Condition compared with the Nonsplinted Condition. No significant reduction in integrated EMG activity occurred during the Splinted Condition compared with the Nonsplinted Condition. Despite the significant change in joint position and elongation of spastic muscles produced by the splinting, the muscle groups accommodated to the position as evidenced by the lack of significant change in EMG activity. Therefore, splinting can effectively control postural defects caused by spastic limb posturing without significantly increasing muscle tone. Implications of the results and the use of EMG measurement to help identify patient candidates for splinting are discussed.

    Recent advances in our understanding and ability to forecast climate variability have meant that skilful predictions are beginning to be routinely made on seasonal to decadal (s2d) timescales. Such forecasts have the potential to be of great value to a wide range of decision-making, where outcomes are strongly influenced by variations in the climate. In 2012 the European Commission funded EUPORIAS, a four year long project to develop prototype end-to-end climate impact prediction services operating on a seasonal to decadal timescale, and assess their value in informing decision-making. EUPORIAS commenced on 1 November 2012, coordinated by the UK Met Office leading a consortium of 24 organisations representing world-class European climate research and climate service centres, expertise in impacts assessments and seasonal predictions, two United Nations agencies, specialists in new media, and commercial companies in climate-vulnerable sectors such as energy, water and tourism. The poster describes the setup of the project, its main outcome and some of the very preliminary results.

    Gamma-ray lines from radioactive decay of unstable isotopes co-produced by nucleosynthesis in massive stars and supernova have been measured since more than thirty years. Over the past ten years, INTEGRAL complemented the first sky survey made by COMPTEL. The {sup 26}A1 isotope with 1 My decay time had been first direct proof of currently-ongoing nucleosynthesis in our Galaxy. This has now become a tool to study the ∼My history of specific source regions, such as massive-star groups and associations in nearby regions which can be discriminated from the galactic-plane background, and the inner Galaxy, where Doppler shifted lines add to the astronomical information about bar and spiral structure. Recent findings suggest that superbubbles show a remarkable asymmetry, on average, in the spiral arms of our galaxy. {sup 60}Fe is co-produced by the sources of {sup 26}A1, and the isotopic ratio from their nucleosynthesis encodes stellar-structure information. Annihilation gamma-rays from positrons in interstellar space show a puzzling bright and extended source region central to our Galaxy, but also may be partly related to nucleosynthesis. {sup 56}Ni and {sup 44}Ti isotope gamma-rays have been used to constrain supernova explosion mechanisms. Here we report latest results using the accumulated multi-year database of INTEGRAL observations, and discuss their astrophysical interpretations, connecting to other traces of cosmic radioactivity and to other cosmic messengers.

    Full Text Available Introduction Penile fracture is a urological emergency caused by direct trauma to an erected penis, tearing the tunica albuginea in the corpus cavernosum. The preferred treatment method is draining the hematoma and surgical repair of tunica albuginea tear as soon as possible following diagnosis. Materials and Methods Forty-nine patients who were diagnosed with penile fracture between January 2009 and December 2014 were reviewed. Physical examination was performed to see the extent of penile hematoma, the side of the penile curvature and the presence of blood in the external meatus. Two patients who were diagnosed with urethrorrhagia underwent retrograde urethrogram for urethral injury. In all patients, penile skin was peeled using a circular subcoronal degloving incision and tunica tear was repaired using absorbable suture materials. The patients were then followed for painful erections, penile deformities and erection angles. Results The average age of the 49 patients, who were included in the study, was 36.5 years (21-65. In their etiological questioning, most patients reported the fracture occurring during sexual intercourse. Retrograde urethrography was indicated in 2 patients with blood in the external meatus and were diagnosed with urethral injury. The patients were taken to emergency surgery. Tunica defects varied between 1 and 2 cm. Incomplete urethral injuries were primarily repaired around 18 French Foley catheter. None of the patients reported penile deformity or painful erections. Their erection angles were found to be within the normal range. Conclusion Even though it is a relatively rare condition, penile fractures are so important that might cause serious complications when not treated surgically. A thorough anamnesis and physical examination suffice for diagnosis.

  2. Public Administration reforms and results

    Full Text Available Research on administrative reforms during the past thirty years indicates that reform efforts of countries differ. The Anglo Saxon states were at the forefront of the New Public Management movement while countries on mainland Europe were more hesitant and moved further towards the Neo-Weberian state. Academics have tried to explain different reform efforts within countries by looking at political, historical and cultural issues, values and economic factors to name just a few. Three hypotheses are put forward to explain reform efforts in different states. This research involves analysing the implementation of two different reform trends, New Public Management and the Neo-Weberian tradition. The analysis indicates that countries vary in their commitment to reform rather than in the emphasis on either New Public Management or the Neo-Weberian State. Decentralization, clear objectives and consultation with communities and experts are closely related to national reform efforts. However, Iceland does distinguish itself from Europe and the Nordic countries. The analysis reveals that although decentralization is high in the Icelandic system, autonomy of agencies does not have a strong relation to a varied use of administrative instruments. The second part of the article focuses on the results and achievements of reform programmes. The achievement of reform programmes are examined in relation to theories of bounded rationality, street level bureaucracy (bottom up and consensus decision making. Three hypotheses are presented and tested to explain what causes reforms programmes to be successful in some countries and not in others. The analysis reveals that countries are more likely to succeed if bounded rationality is applied with careful preparation and when stakeholders are consulted.

  3. Corral Monitoring System assessment results

    1998-03-01

    This report describes the results of a functional and operational assessment of the Corral Monitoring Systems (CMS), which was designed to detect and document accountable items entering or leaving a monitored site. Its development was motivated by the possibility that multiple sites in the nuclear weapons states of the former Soviet Union might be opened to such monitoring under the provisions of the Strategic Arms Reduction Treaty. The assessment was performed at three levels. One level evaluated how well the planned approach addressed the target application, and which involved tracking sensitive items moving into and around a site being monitored as part of an international treaty or other agreement. The second level examined the overall design and development approach, while the third focused on individual subsystems within the total package. Unfortunately, the system was delivered as disassembled parts and pieces, with very poor documentation. Thus, the assessment was based on fragmentary operating data coupled with an analysis of what documents were provided with the system. The system design seemed to be a reasonable match to the requirements of the target application; however, important questions about site manning and top level administrative control were left unanswered. Four weaknesses in the overall design and development approach were detected: (1) poor configuration control and management, (2) inadequate adherence to a well defined architectural standard, (3) no apparent provision for improving top level error tolerance, and (4) weaknesses in the object oriented programming approach. The individual subsystems were found to offer few features or capabilities that were new or unique, even at the conceptual level. The CMS might possibly have offered a unique combination of features, but this level of integration was never realized, and it had no unique capabilities that could be readily extracted for use in another system.

  4. FIRST RESULTS FROM OEDOTENSIOMETRIC TESTS

    Luigi Cavazza

    2008-09-01

    Full Text Available An oedotensiometer was used to examine to examine the behaviour of sieved sample of a swelling soil (a vertisol as well as of the same soils treated with solution of Na+ + Ca2+ to simulate the soil changes from excessive irrigation with brackish water. The oedometer test consisted in an infiltration of water from below through a ceramic porous plate at a feeding pressure of +10 cm water and successive drainage under a depression mostly of -112 cm of water. The rate of water entry as well as the swelling rate of the sample were monitored. Preliminary considerations regards the domains in which the shrinkage curve of a swelling soil is subdivided and make hypothesis on the swelling process expected when the infiltration from below of the sample is applied. The results support the hypothesis that when the water pressure is applied some water enters rather rapidly in the larger structural pores and is followed later by the swelling in the smaller pores, responsible for the basic domain. This first conclusion demonstrates that the assumption of a simultaneous movement of solid and liquid components in the sample, which is the base of most theoretical developments for swelling soils, cannot be accepted for the tested samples. Some cases with water clogging on the sample surface confirm a late final swelling of the soil and permitted to evaluate the hydraulic conductivity of the swollen soil. These manifestations are more evident in sodicated soils. The loading of the sample reduces the swelling of the sample and seems to reduce its permeability. The reduction of the feeding water pressure further reduces the sample swelling. The draining process from saturated soil sample shows that most of the process occurs in the large pores of the structural domain. This gives the possibility to evaluate the water diffusivity coefficient for the structural domain of the sample. In draining the soil with the highest sodication there was a variation of soil volume

    The medium size divertor tokamak ASDEX Upgrade (major and minor radii 1.65 m and 0.5 m, respectively, magnetic-field strength 2.5 T) possesses flexible shaping and versatile heating and current drive systems. Recently the technical capabilities were extended by increasing the electron cyclotron resonance heating (ECRH) power, by installing 2 × 8 internal magnetic perturbation coils, and by improving the ion cyclotron range of frequency compatibility with the tungsten wall. With the perturbation coils, reliable suppression of large type-I edge localized modes (ELMs) could be demonstrated in a wide operational window, which opens up above a critical plasma pedestal density. The pellet fuelling efficiency was observed to increase which gives access to H-mode discharges with peaked density profiles at line densities clearly exceeding the empirical Greenwald limit. Owing to the increased ECRH power of 4 MW, H-mode discharges could be studied in regimes with dominant electron heating and low plasma rotation velocities, i.e. under conditions particularly relevant for ITER. The ion-pressure gradient and the neoclassical radial electric field emerge as key parameters for the transition. Using the total simultaneously available heating power of 23 MW, high performance discharges have been carried out where feed-back controlled radiative cooling in the core and the divertor allowed the divertor peak power loads to be maintained below 5 MW m-2. Under attached divertor conditions, a multi-device scaling expression for the power-decay length was obtained which is independent of major radius and decreases with magnetic field resulting in a decay length of 1 mm for ITER. At higher densities and under partially detached conditions, however, a broadening of the decay length is observed. In discharges with density ramps up to the density limit, the divertor plasma shows a complex behaviour with a localized high-density region in the inner divertor before the outer divertor detaches

    We used southwestern Florida as a case study to lay the groundwork for an intended and organized decision-making process for managing warm-water habitat needed by endangered manatees to survive winters in Florida. Scientists and managers have prioritized (a) projecting how the network of warm-water sites will change over the next 50 years as warmed industrial discharges may expire and as flows of natural springs are reduced through redirection of water for human uses, and (b) mitigating such changes to prevent undue consequences to manatees. Given the complexities introduced by manatee ecology; agency organizational structure; shifting public demands; fluctuating resource availability; and managing within interacting cultural, social, political, and environmental contexts, it was clear that a structured decision process was needed. To help promote such a process, we collected information relevant to future decisions including maps of known and suspected warm-water sites and prototyped a characterization of sites and networks. We propose steps that would lead to models that might serve as core tools in manatee/warm-water decision-making, and we summarized topics relevant for informed decision-making (e.g., manatee spatial cognition, risk of cold-stress morbidity and mortality, and human dimensions). A major impetus behind this effort is to ensure proactively that robust modeling tools are available well in advance of the anticipated need for a critical management decision.

Despite being on different parks, the benthic cover in Dos Mosquises Sur and Cayo Norte was similar (76% based on Bray-Curtis, whereas Caiman differed greatly (57- 68% from all other sites. The cover of hard coral, algae, sponges and octocorals was similar between 2003 and 2004 in all four sites. Similarly, the fish community structure of both parks did not change over time, and was dominated by herbivores (Pomacentridae, Scaridae and Acanthuridae. However, commercially important carnivores (e.g. Lutjanids and Serranids were more abundant in Los Roques than in Morrocoy. Although it was expected that the benthic cover and fish community would reflect greater differences between Los Roques and Morrocoy, only the fish community appeared healthier in Los Roques, whereas Cayo Norte (Morrocoy, had a coral cover similar or higher than both sites of Los Roques. Thus, our results suggest that in Venezuela, oceanic reef sites are not necessarily ‘healthier’ (i.e. higher coral cover than land-influenced coral communities. The addition of three new sites and the reincorporation of Caiman has improved and expanded the monitoring capabilities in Venezuela and it represents the first step towards the consolidation of a coral reef monitoring program for the country.

    2017-10-01

    The magnetic field topology of Lockheed Martin's Compact Fusion Reactor (CFR) concept requires internal magnetic field coils. Internal coils for similar devices have leveraged levitating coils or coils with magnetically guarded supports. Magnetic guarding of supports has been investigated for multipole devices (theoretically and experimentally) without conclusive results. One outstanding question regarding magnetic guarding of supports is the magnitude and behavior of secondary plasma drifts resulting from magnetic guard fields (grad-B drifts, etc). We present magnetic-implicit PIC modeling results and preliminary proof of concept experimental results on magnetic guarding of internal-supports and the subsequent reduction in total plasma losses.

    The laboratory, as a diagnostic department in the hospital, plays an important role in the treatment and prevention of diseases. Paying attention to patients' preferences for communication of test results may provide a better and more responsive system for delivering these results. This study aimed to identify patient preferences regarding receiving their laboratory test results electronically and to identify the reasons behind their choice. Descriptive-analytical study. This study was carried out in 2015 with 200 patients who had access to the internet and had been referred at least once previously to the hospital laboratory department to receive their test results. Data were collected through an expert-validated questionnaire, and its reliability was confirmed by test-retest (P = .8). Data were analyzed using χ2 and marginal independence SPSS and R software. Ninety-eight percent of participants preferred to be notified by short message service when their test results were ready. All participants preferred to receive their test results online, and 82.5% (n = 165) preferred to receive both normal and abnormal test results this way. The main reason for receiving results online was time savings, which was reported by 77% of participants, followed by lowering the chance of missing the results (31%). About 40% of participants thought e-mail notification was more secure than accessing the results through a hospital website. Findings showed that although patients wanted to benefit from online services for receiving their test results, they were concerned about confidentiality and security. Before using online technologies, security measures necessary to protect patient privacy and to gain the trust of patients should be defined.

    2005-01-01

    Full Text Available Background: Management of tibial plateau fractures remains challenging because of their number, variety and associated soft tissue injuries that further augment their complexity. Comparison of operative results in recent reports has been difficult due to a lack of standard fracture classification scheme and uniform standardized objective criteria for evaluating results. Methods: Between August 1998 to December 2002, 27 closed tibial plateau fractures were treated operatively using methods and principles advocated by AO/ASIF and followed up for an average of 35.74 months (range 24-68 months. Fractures were classified according to Schatzker′s staging system and results evaluated using Rasmussen′s 30-point clinical grading system and Rasmussen′s radiological evaluation of the knee at a minimum follow up of 2 years. Results: Type II was the most common fracture type (9 cases followed by type I (6 cases. There were 37% excellent and 51.85% good functional results with only 3 patients having unacceptable results. The mean Rasmussen′s functional score was 25.062 (range 15-30. Minimal fixation in comminuted or depressed fractures as compared to rigid fixation was the cause of unacceptable results. Loss of knee range of motion in a few cases was attributed to delayed knee mobilization in these cases. Using Rasmussen′s radiological grading, 2 patients had excellent results and 81.48 % patients had good results. Only 3 patients had poor radiological results. The mean Rasmussen′s radiological score was 15.33 (range 10-18. Moreover, clinical evaluation did not correlate with the follow up radiograph. Conclusion: Anatomic reduction and rigid internal fixation followed by early knee motion and partial weight bearing during bone healing are the cornerstones in the treatment of tibial plateau fractures. Standard fracture classification, uniform reporting and evaluating criteria, along with detailed analysis of uniform treatment methods, has helped us

    2013-01-01

    Full Text Available Distraction osteogenesis has revolutionised the management of craniofacial abnormalities. The technique however requires precise planning, patient selection, execution and follow-up to achieve consistent and positive results and to avoid unfavourable results. The unfavourable results with craniofacial distraction stem from many factors ranging from improper patient selection, planning and use of inappropriate distraction device and vector. The present study analyses the current standards and techniques of distraction and details in depth the various errors and complications that may occur due to this technique. The commonly observed complications of distraction have been detailed along with measures and suggestions to avoid them in clinical practice.

    2015-05-01

    Full Text Available The growing number of genotyped populations, the advent of high-throughput phenotyping techniques and the development of GWAS analysis software has rapidly accelerated the number of GWAS experimental results. Candidate gene discovery from these results files is often tedious, involving many manual steps searching for genes in windows around a significant SNP. This problem rapidly becomes more complex when an analyst wishes to compare multiple GWAS studies for pleiotropic or environment specific effects. To this end, we have developed a fast and intuitive interactive browser for the viewing of GWAS results with a focus on an ability to compare results across multiple traits or experiments. The software can easily be run on a desktop computer with software that bioinformaticians are likely already familiar with. Additionally, the software can be hosted or embedded on a server for easy access by anyone with a modern web browser.

    1986-01-01

    This paper describes a heat exchanger prototype and test results. The heat exchanger, called a thermal control wall, functions as a skin wall and as a means to vary the exterior wall thermal resistance of a building. Test results confirm that the capacity of the TCW is influenced by solar radiation. Furthermore, this TCW capacity can be evaluated by an overall heat transmission coefficient defined using the same sol air temperature difference as for a conventional wall.

    2008-12-01

    An IWB is a test result that creates uncertainty. Explaining this result to patients can cause provider discomfort but the more the provider practices, the comfort level increases. HIV diagnosis is no longer considered a death sentence. It has become a manageable disease when patients enter care early. That is why it is important to encourage screening for all. The earlier a patient is linked to care the better the health outcome and this prevents ongoing HIV transmission.

  13. Temperament and perception of tooth bleaching results

    2016-09-01

    Full Text Available Background . The neurophysiological process of perceiving the results of tooth bleaching requires the correct interaction between the central nervous system and the organs of sight. Exaggerated beliefs concerning defective facial features may enhance inner attitudes about one’s own color of dentition, as well as a feeling of dissatisfaction with the degree of leaching. Objectives. The study aimed to assess the degree of the patient satisfaction with the results of tooth bleaching in relation to their temperament. Material and methods. There were 68 generally healthy volunteers, aged 28–38 years, with external discolorations of the teeth. They had never undergone dental bleaching and their frontal teeth did not have any fillings. After clinical evaluation and the completion of formalities, the patients were asked to fill in Strelau’s temperament questionnaire. Questionnaires and visual status were assessed three times by three doctors: before bleaching, and then 24 hours and two weeks after the home-bleaching operation, which was done with the use of Opalescence (Ultradent in uniform sequence. Results . There were practically no adverse side results, except a periodic dentin hypersensitivity that occurred periodically in 44 patients. The results of the visual assessment performed by the physicians did not differ. The questionnaire data showed that women were more critical of the results in relation to the expectations. Among elancholics, full satisfaction was declared by 41%, whereas among sanguine people, full satisfaction was obtained by 85%. Satisfaction with the aesthetic results was associated with bleaching by at least 4 degrees. Conclusions . Patients’ temperament affects their subjective evaluation of the effectiveness of tooth bleaching, which should be taken into consideration in the patient’s individual dental treatment plan.

  14. Ranking schools on external knowledge tests results

    Directory of Open Access Journals (Sweden)

    Gašper Cankar

    2007-01-01

    Full Text Available The paper discusses the use of external knowledge test results for school ranking and the implicit effect of such ranking. A question of validity is raised and a review of research literature and main known problems are presented. In many western countries publication of school results is a common practice and a similar trend can be observed in Slovenia. Experiences of other countries help to predict positive and negative aspects of such publication. Results of external knowledge tests produce very limited information about school quality—if we use other sources of information our ranking of schools can be very different. Nevertheless, external knowledge tests can yield useful information. If we want to improve quality in schools, we must allow schools to use this information themselves and improve from within. Broad public scrutiny is unnecessary and problematic—it moves the focus of school efforts from real improvement of quality to mere improvement of the school public image.

    Full Text Available This article presents the results of the ethnical distance measuring in Vojvodina, the north Province of the Republic of Serbia. The measuring was carried out on autumn 2002, during realization of the wider project of multiculturalism research in the mentioned region. According to the results the ethnical distances in Vojvodina are quite equalized and they are grouped around the attitude "all the same". Vojvodinian Serbs are more favorable partners for the majority of social contacts, and the relatively largest distance is shown toward Roma. The ethnical distance results also discovers two very important factors for understanding the interethnic relations in Vojvodina: first, the "rational" kind of social contacts with the members of the other ethnical groups are more preferable for the majority of respondents, and second, they have very equal distances toward their own ethnical groups.

    1996-09-01

    Ambient air samples were taken at two locations in the East Mountain Area in conjunction with thermal testing at the Lurance Canyon Burn Site (LCBS). The samples were taken to provide measurements of particulate matter with a diameter less than or equal to 10 micrometers (PM{sub 10}) and volatile organic compounds (VOCs). This report summarizes the results of the sampling performed in 1995. The results from small-scale testing performed to determine the potentially produced air pollutants in the thermal tests are included in this report. Analytical results indicate few samples produced measurable concentrations of pollutants believed to be produced by thermal testing. Recommendations for future air sampling in the East Mountain Area are also noted.

    1998-09-01

    The authors present the preliminary results of 20 patients selected to be operated on between January 1996 and April 1997. These patients presented one of the present indications for stereotactic posteroventral pallidotomy (PVP), such as: rigidity, akinesia/bradykinesia, gait dysfunction, drug induced dyskinesias and tremor. Every patient of this protocol was evaluated by: UPDRS score, Schwab and England scale, Hoehn and Yahr Staging Scale before and after surgery. The results in 3 months showed a remarkable improvement after PVP (P < 0.01) in all functional assessments, except for facial expression, speech and posture. The morbidity was 5%. 5 patients (25%) who were in Hoehn and Yahr 5 underwent a bilateral simultaneous PVP. In 5 patients (25%), who had tremor, during the PVP, VIM thalamotomy was added. These preliminary results, suggest that PVP is highly effective for PD symptoms.

    Full Text Available Recent results from the Double Chooz experiment on the neutrino mixing angle θ13 are presented. Two detectors are located at distances of 400m and 1050m from the reactor cores of the Chooz nuclear power plant, to measure the original neutrino flux from the reactor cores and the disappearance of neutrinos, respectively. The Far Detector has taken data since 2011 while the Near Detector started the data taking in 2014. The latest far detector only result with gadolinium capture events is sin2 2θ13=0.090+0.032.-0.029. Studies using hydrogen capture events also have been improved and the combined result of gadolinium and hydrogen capture events is obtained as sin2 2θ13 = 0.088 ± 0.033.

    Esumi Shinlchi

    2013-05-01

    Full Text Available Recent results from heavy ion collision experiments from RHIC at BNL are presented and discussed in terms of Quark Gluon Plasm properties, such as partonic collectivity and partonic energy loss. The experimental results with direct photons and heavy quarks have given important additional insights of the plasma on top of what has been known with light hadrons. Higher order event anisotropies and the related results have provided the geometrical, temporal and dynamical information of the plasma. The beam energy dependence of the various measurements could reveal the structure of QCD phase diagram and possibly the critical point in the diagram, where the properties of phase transition are expected to change drastically.

  1. PHENIX Results in d + Au Collisions

    Science.gov (United States)

    Chen, Chin-Hao

    2016-04-01

    The PHENIX experiment at the Relativistic Heavy Ion Collider has performed a comprehensive set of measurements in d + Au collisions. Observables in d + Au collisions were originally conceived as a control experiment where no quark-gluon plasma is formed and one could isolate so-called cold nuclear matter effects, including nuclear modified parton distributions and parton multiple scattering. However, recent data from the PHENIX experiment in d + Au, in conjunction with new p + Pb results at the Large Hadron Collider, give strong evidence for a very different picture. We present new results that hint at the formation of a small quark-gluon plasma, that though short lived, leaves a fingerprint of evidence on final state observables. These new results will be discussed in the context of competing theoretical interpretations.

  2. How to present and publish research results

    2014-01-01

    Full Text Available The end of each research is to present its results to the public, especially to those who are engaged in similar research. This is particularly true for scientific research. Scientific paper is written report that contains a presentation of the results of the original scientific research. Its format is defined by centuries-old tradition of writing, the editorial practices of the publishers, scientific ethics, accepted standards and requirements of modern printing and publishing. Unfortunately, the experience of the publishers and editors of scientific books and journals show that a large number of submitted contributions are not meeting the minimum requirements to be even considered. This article indicates the most important principles that one should have in mind during creation of full text paper or presentation of scientific results.

    2017-01-01

    Despite the great progress achieved in the last decades, neutrinos remain among the least understood fundamental particles to have been experimentally observed. The Daya Bay Reactor Neutrino Experiment consists of eight identically designed detectors placed underground at different baselines from three groups of nuclear reactors in China, a configuration that is ideally suited for studying the properties of these elusive particles. In this talk I will review the improved results released last summer by the Daya Bay collaboration. These results include (i) a precision measurement of the θ13 mixing angle and the effective mass splitting in the electron antineutrino disappearance channel with a dataset comprising more than 2.5 million antineutrino interactions, (ii) a high-statistics measurement of the absolute flux and spectrum of reactor-produced electron antineutrinos, and (iii) a search for light sterile neutrino mixing performed with more than three times the statistics of the previous result.

  5. Annotating images by mining image search results.

    Wang, Xin-Jing; Zhang, Lei; Li, Xirong; Ma, Wei-Ying

    2008-11-01

    Although it has been studied for years by the computer vision and machine learning communities, image annotation is still far from practical. In this paper, we propose a novel attempt at model-free image annotation, which is a data-driven approach that annotates images by mining their search results. Some 2.4 million images with their surrounding text are collected from a few photo forums to support this approach. The entire process is formulated in a divide-and-conquer framework where a query keyword is provided along with the uncaptioned image to improve both the effectiveness and efficiency. This is helpful when the collected data set is not dense everywhere. In this sense, our approach contains three steps: 1) the search process to discover visually and semantically similar search results, 2) the mining process to identify salient terms from textual descriptions of the search results, and 3) the annotation rejection process to filter out noisy terms yielded by Step 2. To ensure real-time annotation, two key techniques are leveraged-one is to map the high-dimensional image visual features into hash codes, the other is to implement it as a distributed system, of which the search and mining processes are provided as Web services. As a typical result, the entire process finishes in less than 1 second. Since no training data set is required, our approach enables annotating with unlimited vocabulary and is highly scalable and robust to outliers. Experimental results on both real Web images and a benchmark image data set show the effectiveness and efficiency of the proposed algorithm. It is also worth noting that, although the entire approach is illustrated within the divide-and conquer framework, a query keyword is not crucial to our current implementation. We provide experimental results to prove this.

    2017-04-01

    To determine if the OOPS index is predictive of long-term hearing results after ossiculoplasty. Case series with retrospective chart review. Tertiary care otology practice. Adult and pediatric patients (3-88 years of age). Ossiculoplasty with cartilage tympanoplasty, with or without mastoidectomy. Primary outcome measures included short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 days and 1 year after surgery), long-term hearing results (PTA-ABG measured ≥5 years after surgery), and the rate of successful ABG closure to ≤20 dB. Secondary measures included the need for revision surgery, delayed tympanic membrane graft failure, worsening conductive hearing loss (after an initially satisfactory hearing result), and recurrence of cholesteatoma. There was no significant difference between adults and children for short-term hearing results (average post-op PTA-ABG was 18.9 dB vs. 19.8 dB, respectively; p = 0.544), long-term hearing results (average final PTA-ABG was 19.3 dB vs. 19.4 dB, respectively; p = 0.922), or rate of ABG closure to less than 20 dB (63.1% vs. 58.0%, p = 0.282). Spearman's rank-order correlation (ρ) identified a strong positive correlation between OOPS index score and average post-operative PTA-ABG (ρ = 0.983; p hearing outcomes in adult and pediatric patients undergoing ossiculoplasty in both the short term and the long term.

    The duality between the partonic and hadronic descriptions of electron--nucleon scattering is a remarkable feature of nuclear interactions. When averaged over appropriate energy intervals the cross section at low energy which is dominated by nucleon resonances resembles the smooth behavior expected from perturbative QCD. Recent Jefferson Lab results indicate that quark-hadron duality is present in a variety of observables, not just the proton F2 structure function. An overview of recent results, especially local quark-hadron duality on the neutron, are presented here.

    Full Text Available Résumé. Searches for Higgs bosons in different extensions of the Standard Model (SM are presented. These include the Minimal Supersymmetric extension of the SM (MSSM, the next-to-MSSM (NMSSM, models with additional scalar singlets, doublets, or triplets, and generic searches for models with couplings modified with respect to the SM or for non-SM Higgs boson decay channels. Results are based on data collected by the ATLAS and CMS experiments in 2011 and 2012 at the LHC. No excess is found in any of the searches and thus the resulting exclusion limits are given.

    1994-05-01

    A Gaussian model of self-avoiding walks is studied. Not only is any cluster integral exactly evaluable, but whole sub-series can be evaluated exactly in terms of associated Riemann zeta functions. The results are compared with information recently obtained on self-avoiding walks on the plane square and simple cubic lattices and, as expected, are very similar. Use is made of the author's recent result that the reciprocal of the walks generating function is the generating function for irreducible cluster-sums. This is split into sub-series all of which have the same radius of convergence, and the significance of this is discussed.

    We need to know uncertainties and systematic errors because we create and compare against archival weapons data, we constrain the models, and we provide scientific results. Good estimates of precision from the data record are available and should be incorporated into existing results; reanalysis of valuable data is suggested. Estimates of systematic errors are largely absent. The original work by Jensen et al. using gun shots for window corrections, and the integrated velocity comparison with X-rays by Schultz are two examples where any systematic errors appear to be <1% level.

    Recent results from the four experiments ALEPH, DELPHI, L3 and OPAL at the Large Electron-Positron collider, LEP at CERN, and by the SLD collaboration at the Stanford Linear Collider, SLC, are reviewed. Analyses from an integrated luminosity of about 150 pb/sup -1/ recorded by each experiment at LEP, taken at different centre-of-mass energies within +or-3 GeV around the peak of the Z resonance during the years 1989 to 1995 are available now. Repeated accurate calibrations of the beam energy lead to precise measurements of the mass and of the total width of the Z boson. These results are complemented by measurements at the Z resonance with polarised beams at Stanford. First results from an integrated luminosity of close to 100 pb/sup -1/ per experiment above the threshold for W boson pair production were also presented recently by the LEP collaborations. Together with measurements of the top quark and W boson masses at the Tevatron pp collider at Fermilab these results provide tests of the Standard Model of th...

  11. Experimental results from the small isochronous ring

    Energy Technology Data Exchange (ETDEWEB)

    Eduard Pozdeyev

    2005-05-01

    The Small Isochronous Ring (SIR) is a compact, low-energy storage ring designed to investigate the beam dynamics of high-intensity isochronous cyclotrons and synchrotrons at the transition energy. The ring was developed at Michigan State University (MSU) and has been operational since December 2003. It stores 20 keV hydrogen beams with a peak current of 10-20 microamps for up to 200 turns. The transverse and longitudinal profiles of extracted bunches are measured with an accuracy of approximately 1 mm. The high accuracy of the measurements makes the experimental data attractive for validation of multi-particle space charge codes. The results obtained in the ring show a fast growth of the energy spread induced by the space charge forces. The energy spread growth is accompanied by a breakup of the beam bunches into separated clusters that are involved in the vortex motion specific to the isochronous regime. The experimental results presented in the paper show a remarkable agreement with simulations performed with the code CYCO. In this paper, we discuss specifics of space charge effects in the isochronous regime, present results of experiments in SIR, and conduct a detailed comparison of the experimental data with results of simulations.

  19. Astronomical optical interferometry, II: Astrophysical results

    2011-01-01

    Full Text Available Optical interferometry is entering a new age with several ground- based long-baseline observatories now making observations of unprecedented spatial resolution. Based on a great leap forward in the quality and quantity of interferometric data, the astrophysical applications are not limited anymore to classical subjects, such as determination of fundamental properties of stars; namely, their effective temperatures, radii, luminosities and masses, but the present rapid development in this field allowed to move to a situation where optical interferometry is a general tool in studies of many astrophysical phenomena. Particularly, the advent of long-baseline interferometers making use of very large pupils has opened the way to faint objects science and first results on extragalactic objects have made it a reality. The first decade of XXI century is also remarkable for aperture synthesis in the visual and near-infrared wavelength regimes, which provided image reconstructions from stellar surfaces to Active Galactic Nuclei. Here I review the numerous astrophysical results obtained up to date, except for binary and multiple stars milliarcsecond astrometry, which should be a subject of an independent detailed review, taking into account its importance and expected results at microarcsecond precision level. To the results obtained with currently available interferometers, I associate the adopted instrumental settings in order to provide a guide for potential users concerning the appropriate instruments which can be used to obtain the desired astrophysical information.

  6. Long term results of mandibular distraction

    Directory of Open Access Journals (Sweden)

    Batra Puneet

    2006-03-01

    Full Text Available Mandibular distraction osteogenesis has become a popular surgical modality due to its many advantages over conventional orthognathic surgical procedures. However, in spite of the technique having been used for over 15 years, no concrete long term results are available regarding the stability of results. We discuss the various studies which have reported either in favour or against the stablility of results after distraction. We report a series of 6 cases (3 unilateral and 3 bilateral distraction where distraction was carried out before puberty and followed them up to seven years after removal of distractors. This case series shows that results achieved by distraction osteogenesis are unstable or best unpredictable with respect to producing a permanent size increase in the mandible. The role of the distraction osteogenesis in overcoming the pterygomassetric sling is questionable. We suggest a multicenter study with adequate patient numbers treated with a similar protocol and documented after growth cessation to have meaningful conclusions on the debate of distraction osteogenesis versus orthognathic surgery.

  12. Estimating Nitrogen Load Resulting from Biofuel Mandates

    Directory of Open Access Journals (Sweden)

    Mohammad Alshawaf

    2016-05-01

    Full Text Available The Energy Policy Act of 2005 and the Energy Independence and Security Act (EISA of 2007 were enacted to reduce the U.S. dependency on foreign oil by increasing the use of biofuels. The increased demand for biofuels from corn and soybeans could result in an increase of nitrogen flux if not managed properly. The objectives of this study are to estimate nitrogen flux from energy crop production and to identify the catchment areas with high nitrogen flux. The results show that biofuel production can result in an increase of nitrogen flux to the northern Gulf of Mexico from 270 to 1742 thousand metric tons. Using all cellulosic (hay ethanol or biodiesel to meet the 2022 mandate is expected to reduce nitrogen flux; however, it requires approximately 25% more land when compared to other scenarios. Producing ethanol from switchgrass rather than hay results in three-times more nitrogen flux, but requires 43% less land. Using corn ethanol for 2022 mandates is expected to have double the nitrogen flux when compared to the EISA-specified 2022 scenario; however, it will require less land area. Shifting the U.S. energy supply from foreign oil to the Midwest cannot occur without economic and environmental impacts, which could potentially lead to more eutrophication and hypoxia.

    Recent cavity results with niobium have demonstrated the necessity of a good understanding of both the BCS and residual resistance. For a complete picture and comparison with theory, it is essential that one can measure the RF properties as a function of field, temperature, frequency and ambient magnetic field. Standard cavity measurements are limited in their ability to change all parameters freely and in a controlled manner. On the other hand, most sample measurement setups operate at fairly high frequency, where the surface resistance is always BCS dominated. The quadrupole resonator, originally developed at CERN, is ideally suited for characterization of samples at typical cavity RF frequencies. We report on a modified version of the QPR with improved RF figures of merit for high-field operation. Experimental challenges in the commissioning run and alternate designs for simpler sample changes are shown alongside measurement results of a large grain niobium sample.

    Simultaneous detection of the Čerenkov light and scintillation light produced in hadron showers makes it possible to measure the electromagnetic shower fraction event by event and thus eliminate the detrimental effects of fluctuations in this fraction on the performance of calorimeters. In the RD52 (DREAM) project, the possibilities of this dual-readout calorimetry are investigated and optimized. In this talk, the latest results of this project will be presented. These results concern tests of a dual-readout fiber calorimeter with electrons at very small angles of incidence, detailed measurements of the time structure of hadron showers in this detector, as well as elaborate comparisons of various aspects of the calorimeter performance with GEANT4 simulations.

    Previous testing by BSRI/SRTC/Raytheon indicated that the CLSM specified for the Tank 20 closure generates about 6 gallons (23 liters) of bleed water per cubic yard of material (0.76 m3).1 This amount to about 10 percent of the total mixing water. HLWE requested that the CLSM mix be optimized to reduce bleed water while maintaining flow. Elimination of bleed water from the CLSM mix specified for High-Level Waste Tank Closure will result in waste minimization, time savings and cost savings. Over thirty mixes were formulated and evaluated at the on-site Raytheon Test Laboratory. Improved low bleed water CLSM mixes were identified. Results are documented in this report.

    Full Text Available The platform switching (PLS concept was introduced in the literature in 2005. The biological benefits and clinical effectiveness of the PLS technique have been established by several studies. In this article different aspects of PLS concept are discussed. Crestal bone loss, biologic width, and stress distribution in this concept are comprehensively reviewed. In this article the relative published articles from 1990 to 2011 have been evaluated by electronic search. Because of controversial results especially in immediate loading and animal studies, further modified research is needed to establish the mechanism and effect of the PLS technique. Essential changes in studies including using the control group for accurate interpretation of results and long-term observation, particularly through, randomized, prospective, multicenter trials with large numbers of participants, and implants are necessary.

    Background and purpose During the past 40 years, several attempts have been made with total wrist arthroplasty to avoid fusion in severely destroyed wrists. The results have often been disappointing. There is only modest clinical documentation due to the small number of patients (especially non......-rheumatoid cases) and short follow-up times. Here we report a multicenter series using a third-generation implant with a minimum follow-up time of 5 years. Methods In 2012, data were retrieved from a registry of consecutive wrist operations at 7 centers with units specialized in hand surgery, between 2003 and 2007....... The wrists had been reviewed annually and analysis was done on the latest follow-up data. Results 60 patients had been operated (5 bilaterally), 5 wrists had been revised, and 52 were available for follow-up (with the revised cases excluded).

    Full Text Available In the framework of a nationally funded project, a Ground Penetrating Radar (GPR has been developed by the Italian Consortium for Research on Advanced Remote Sensing Systems (CO.RI.S.T.A.. The system was described in a previous paper (Alberti et al., 2002. As new aspects, the system is a stepped frequency GPR that can work both in gated and ungated mode, and the antennas can be moved automatically in a controlled fashion. As aspects of geophysical interest, the system is exploitable in situations wherein a high resolution and a shallow penetration in the soil (a few meters are required. Possibly, this is an example of probing a landscape. This paper completes the results of Alberti et al. (2002, wherein laboratory tests where described, by providing the main results obtained during an outdoor experimental campaign, performed fi rst in a controlled site and then in an archaeological site.

  4. Confidence crisis of results in biomechanics research.

    Science.gov (United States)

    Knudson, Duane

    2017-11-01

    Many biomechanics studies have small sample sizes and incorrect statistical analyses, so reporting of inaccurate inferences and inflated magnitude of effects are common in the field. This review examines these issues in biomechanics research and summarises potential solutions from research in other fields to increase the confidence in the experimental effects reported in biomechanics. Authors, reviewers and editors of biomechanics research reports are encouraged to improve sample sizes and the resulting statistical power, improve reporting transparency, improve the rigour of statistical analyses used, and increase the acceptance of replication studies to improve the validity of inferences from data in biomechanics research. The application of sports biomechanics research results would also improve if a larger percentage of unbiased effects and their uncertainty were reported in the literature.

    The REXEDIS is an Electron Beam Ion Source (EBIS) developed particularly for charge breeding of rare and short-lived isotopes produced at ISOLDE for the REX-ISOLDE post accelerator. Bunches of singly charged radioactive ions are injected into the EBIS and charge bred to a charge-to-mass ratio of approximately 1/4 and thereafter extracted and injected into a short LINAC. This novel concept, employing a Penning trap to bunch and cool the ions from an on-line mass separator prior to charge breeding in an EBIS, results in an efficient and compact system. In this article the final REXEBIS design is presented together with results from the first tests. (19 refs).

  6. Relativity concept inventory: Development, analysis, and results

    2013-05-01

    Full Text Available We report on a concept inventory for special relativity: the development process, data analysis methods, and results from an introductory relativity class. The Relativity Concept Inventory tests understanding of relativistic concepts. An unusual feature is confidence testing for each question. This can provide additional information; for example, high confidence correlated with incorrect answers suggests a misconception. A novel aspect of our data analysis is the use of Monte Carlo simulations to determine the significance of correlations. This approach is particularly useful for small sample sizes, such as ours. Our results show a gender bias that was not present in course assessment, similar to that reported for the Force Concept Inventory.

    The NA61/SHINE experiment aims to discover the critical point of strongly interacting matter and study the properties of the onset of deconfinement. For these goals a scan of the two dimensional phase diagram (T-$\\mu_B$) is being performed at the SPS by measurements of hadron production in proton-proton, proton-nucleus and nucleus-nucleus interactions as a function of collision energy and system size. In this contribution intriguing results on the energy dependence of hadron spectra and yields in inelastic p+p and centrality selected Be+Be collisions will be presented. In particular, the energy dependence of the signals of deconfinement, the 'horn', 'step' and 'kink', in p+p interactions will be presented and compared with the corresponding results from central Pb+Pb collisions from NA49.

    The tracking system of the CMS detector provides excellent resolution for charged particle tracks and an efficient way of tagging jets. In order to reconstruct good quality tracks, the position and orientation of each silicon pixel and strip module needs to be determined with a precision of several micrometers. The presented alignment results are derived following a global (Millepede-II) and a local (HipPy) fit approach. The performance of the CMS tracker alignment in 2016 using cosmic-ray data and the complete set of proton-proton collision data recorded at 3.8 T magnetic field has been studied. The data-driven validation of the results are shown. The time-dependent movement of the pixel detector's large-scale structure is demonstrated.

    The aerodynamic flight test procedures and results for the Space Shuttle orbiter are presented. The aerodynamic characteristics used in testing were determined from flights STS-1 and through STS-4. Normal force and pitching moment were different than predicted, suggesting an unanticipated aerodynamic force acting upward on the end of the orbiter. However, lateral-directional aerodynamic characteristics were in good management with good predictions. The flight measured aerodynamics are repeatable and show good correlation with angle of attack and angle of sideslip.

  1. Cortical Neural Computation by Discrete Results Hypothesis.

    Science.gov (United States)

    Castejon, Carlos; Nuñez, Angel

    2016-01-01

    One of the most challenging problems we face in neuroscience is to understand how the cortex performs computations. There is increasing evidence that the power of the cortical processing is produced by populations of neurons forming dynamic neuronal ensembles. Theoretical proposals and multineuronal experimental studies have revealed that ensembles of neurons can form emergent functional units. However, how these ensembles are implicated in cortical computations is still a mystery. Although cell ensembles have been associated with brain rhythms, the functional interaction remains largely unclear. It is still unknown how spatially distributed neuronal activity can be temporally integrated to contribute to cortical computations. A theoretical explanation integrating spatial and temporal aspects of cortical processing is still lacking. In this Hypothesis and Theory article, we propose a new functional theoretical framework to explain the computational roles of these ensembles in cortical processing. We suggest that complex neural computations underlying cortical processing could be temporally discrete and that sensory information would need to be quantized to be computed by the cerebral cortex. Accordingly, we propose that cortical processing is produced by the computation of discrete spatio-temporal functional units that we have called "Discrete Results" (Discrete Results Hypothesis). This hypothesis represents a novel functional mechanism by which information processing is computed in the cortex. Furthermore, we propose that precise dynamic sequences of "Discrete Results" is the mechanism used by the cortex to extract, code, memorize and transmit neural information. The novel "Discrete Results" concept has the ability to match the spatial and temporal aspects of cortical processing. We discuss the possible neural underpinnings of these functional computational units and describe the empirical evidence supporting our hypothesis. We propose that fast-spiking (FS

    The CHAMP (Challenging Minisatellite Payload) mission's unique combination of sensors and orbit configuration will enable unprecedented improvements in modeling and understanding the Earth's static gravity field and its temporal variations. CHAMP is the first of two missions (GRACE (Gravity Recovery and Climate Experiment) to be launched in the later part of '01) that combine a new generation of GPS (Global Positioning System) receivers, a high precision three axis accelerometer, and star cameras for the precision attitude determination. In order to isolate the gravity signal for science investigations, it is necessary to perform a detailed reduction and analysis of the GPS and SLR tracking data in conjunction with the accelerometer and attitude data. Precision orbit determination based on the GPS and SLR (Satellite Laser Ranging) tracking data will isolate the orbit perturbations, while the accelerometer data will be used to distinguish the surface forces from those due to the geopotential (static, and time varying). In preparation for the CHAMP and GRACE missions, extensive modifications have been made to NASA/GSFC's GEODYN orbit determination software to enable the simultaneous reduction of spacecraft tracking (e.g. GPS and SLR), three axis accelerometer and precise attitude data. Several weeks of CHAMP tracking and accelerometer data have been analyzed and the results will be presented. Precision orbit determination analysis based on tracking data alone in addition to results based on the simultaneous reduction of tracking and accelerometer data will be discussed. Results from a calibration of the accelerometer will be presented along with the results from various orbit determination strategies. Gravity field modeling status and plans will be discussed.

    Full Text Available Introduction: The flower industry has been affected for years by the high occurrence of muscu¬loskeletal disorders among workers. Various efforts have been done to understand the magnitude of the problem, its causes and possible solutions. This manuscript presents from the academic perspective the lessons and achievements of an industry-academics model of action to improve the ergonomic conditions of the working population of this important industry. Materials and methods: I conducted a review of minutes, communications, reports and scientific publications related to the ergonomics work done since year 2007 with the participation of the Center for Ergonomics Studies (cee of the Department of Industrial Engineering at Pontificia Universidad Javeriana. A retrospective analysis of the information sought to answer questions about the origin of the work, objectives, results, lessons learned and benefits gained. Results: The working model was participatory. Flower producers were the starters of the work. They made explicit their needs to workers’ insurance companies. The overall study design was not just given but built with academics, and subsequently refined with the association of producers. Although the overall objective of the work was the prevention of musculoskeletal disease among workers, the work was carried out in time as funds were secured through studies with specific objectives related to: Workplace ergonomics evaluations, characterization of the working population, and the development, implementation and testing of solutions. Discussion: The presented industry-academics collaboration model resulted in important improvements to working conditions and academic results. Although it is necessary to validate the view of the industry regarding this type of collaborative models, it is considered that this case was successful and therefore should be replicated in other industries.

    The PHENIX experiment has conducted searches for the QCD critical point with measurements of multiplicity fluctuations, transverse momentum fluctuations, event-by-event kaon-to-pion ratios, elliptic flow, and correlations. Measurements have been made in several collision systems as a function of centrality and transverse momentum. The results do not show significant evidence of critical behavior in the collision systems and energies studied, although several interesting features are discussed.

    2010-10-01

    Sample surveys are widely used in the social sciences and business. The news media almost daily quote from them, yet they are widely misused. Using students with prior managerial experience embarking on an MBA course, we show that common sample survey results are misunderstood even by those managers who have previously done a statistics course. In general, they fare no better than managers who have never studied statistics. There are implications for teaching, especially in business schools, as well as for consulting.

    2014-03-01

    Full Text Available The Enriched Xenon Observatory (EXO is an experimental program searching for neutrinoless double-beta decay using 136Xe. Such a search can shed light on the Majorana nature of the neutrino (whether the neutrino is its own anti-particle, the absolute mass scale of neutrinos, and beyond standard model processes that violate lepton number conservation. The first phase of the experiment, EXO-200, uses 200 kg of xenon with 80% enrichment in 136Xe in a single-phase liquid xenon time projection chamber (TPC. The double-beta decay of xenon is detected in the ultra-low background TPC by collecting both the scintillation light and the ionization charge. The detector has been taking low background physics data with enriched xenon at the Waste Isolation Pilot Plant (WIPP in New Mexico since early May 2011. The results produced from the collaboration include the first observation of two-neutrino double-beta decay of 136Xe, and a neutrinoless double-beta decay search result that places one of the most stringent limits on the effective Majorana neutrino mass. Building on the success of EXO-200, the collaboration is performing feasibility studies and R&D work for a future multi-tonne scale experiment named nEXO. During the talk, I will discuss the latest results from EXO-200 and prospects of neutrinoless double-beta decay search with both EXO-200 and nEXO.

    2016-01-01

    Full Text Available The paper presents an overview of results for wing-body interference, obtained by the author for varied wing-body combinations. The lift-curve slopes of the wing-body combinations are considered. In this paper a discrete vortices method (DVM and 2D potential model for cross-flow around fuselage are used. The circular and elliptical cross-sections of the fuselage and flat wings of various forms are considered. Calculations showed that the value of the lift-curve slopes of the wing-body combinations may exceed the same value for an isolated wing. This result confirms an experimental data obtained by other authors earlier. Within a framework of the used mathematical models the investigations to optimize the wing-body combination were carried. The present results of the optimization problem for the wing-body combination allowed to select the optimal geometric characteristics for configuration to maximize the values of the lift-curve slopes of the wing-body combination. It was revealed that maximums of the lift-curve slopes for the optimal mid-wing configuration with elliptical cross-section body had a sufficiently large relative width of the body (more than 30% of the span wing.

    Full Text Available Background: Posterior endoscopic discectomy is an established method for treatment of lumbar disc herniation. Many studies have not been reported in literature for lumbar discectomy by Destandau Endospine System. We report a series of 300 patients operated for lumbar dissectomy by Destandau Endospine system. Materials and Methods: A total of 300 patients suffering from lumbar disc herniations were operated between January 2002 and December 2008. All patients were operated as day care procedure. Technique comprised localization of symptomatic level followed by insertion of an endospine system devise through a 15 mm skin and fascial incision. Endoscopic discectomy is then carried out by conventional micro disc surgery instruments by minimal invasive route. The results were evaluated by Macnab′s criteria after a minimum followup of 12 months and maximum up to 24 months. Results: Based on modified Macnab′s criteria, 90% patients had excellent to good, 8% had fair, and 2% had poor results. The complications observed were discitis and dural tear in five patients each and nerve root injury in two patients. 90% patients were able to return to light and sedentary work with an average delay of 3 weeks and normal physical activities after 2 months. Conclusion: Edoscopic discectomy provides a safe and minimal access corridor for lumbar discectomy. The technique also allows early postoperative mobilization and faster return to work.

    Full Text Available Objective: To assess the influence of age on the patch-test results and to compare the profiles of skin sensitizers according to the age groups. Methods: It is an 8-year retrospective study involving entire medical records of the patients with allergic contact dermatitis at the Unity of Dermatology and Allergology in the Department of Occupational Medicine, University Hospital of Sousse in Tunisia. Study population was divided into two age groups (group 1: patients 40 years. The statistical significance level was taken as p<0.05. Results: Among the patients, 586 have had at least one positive reaction to the patch-test. Older individuals were 1.1 times more likely to have at least one positive reaction to the patch-test than younger ones. The most common allergens in both groups are potassium dichromate (34.2% vs. 38%, thiuram mix (6% vs. 11%, cobalt chloride (27% vs. 28.8%, balsam of Peru (6% vs. 11.3% and nickel sulphate (41% vs. 27.3%. A significant variation was noted for potassium dichromate in terms of intensity of skin reaction (p=0.00. Conclusion: More research is needed to elucidate the physiologic mechanisms of age on the patch-test results and to adapt the European Standard Battery to each age group in term of allergen type and their appropriate concentration.

    Enova is a state-owned enterprise, owned by the Norwegian Ministry of Petroleum and Energy. Over a period of ten years, the enterprise has worked to trigger energy efficiency measures and renewable energy production by supporting proactive players that have paved the way for others. In the period 2002-2011, Enova has contracted an energy result of 16.6 TWh, Enova's Annual Report 2011 shows. This corresponds to the annual energy end-use of more than 35 per cent of Norways 2.2 million private households. Enova has allocated NOK 9 billion in support over ten years. This has resulted in project owners and other financiers investing about Nok 45 billion in capital for environmentally friendly energy projects in Norway, says Nils Kristian Nakstad, CEO of Enova. In 2011, Enova supported projects with an overall energy result of 1.35 TWh using resources from the Energy Fund, equally distributed between energy efficiency and renewable heating. The greatest contributors in 2011 are within energy conversion to renewable heating and energy efficiency measures in buildings.The climate impact of all of the projects where Enova has entered into contracts corresponds to 9.3 million tonnes in reduced CO2 emissions annually. The latter constitutes 17 per cent of domestic greenhouse gas emissions. (au)

  20. Electronic cigarette solutions and resultant aerosol profiles.

    2015-10-30

    Electronic cigarettes (e-cigarettes) are growing in popularity exponentially. Despite their ever-growing acceptance, their aerosol has not been fully characterized. The current study focused on evaluating e-cigarette solutions and their resultant aerosol for potential differences. A simple sampling device was developed to draw e-cigarette aerosol into a multi-sorbent thermal desorption (TD) tube, which was then thermally extracted and analyzed via a gas chromatography (GC) mass spectrometry (GC-MS) method. This novel application provided detectable levels of over one hundred fifteen volatile organic compounds (VOCs) and semivolatile organic compounds (SVOCs) from a single 40mL puff. The aerosol profiles from four commercially available e-cigarettes were compared to their respective solution profiles with the same GC-MS method. Solution profiles produced upwards of sixty four unidentified and identified (some only tentatively) constituents and aerosol profiles produced upwards of eighty two compounds. Results demonstrated distinct analyte profiles between liquid and aerosol samples. Most notably, formaldehyde, acetaldehyde, acrolein, and siloxanes were found in the aerosol profiles; however, these compounds were never present in the solutions. These results implicate the aerosolization process in the formation of compounds not found in solutions; have potential implications for human health; and stress the need for an emphasis on electronic cigarette aerosol testing.

  1. Pulmonary biochemical alterations resulting from ozone exposure

    Energy Technology Data Exchange (ETDEWEB)

    Mustafa, M.G.; Lee, S.D.

    1976-07-01

    Metabolic response of lung tissue to ozone was studied in rats and monkeys after exposure of animals to various levels of ozone (0.1 to 0.8 ppM) for 1 to 30 days. In rats, 0.8 ppM ozone exposure resulted in a 40 to 50 percent augmentation of oxygen utilization in lung homogenate in the presence of an added substrate (e.g., succinate or 2-oxoglutarate). Activities of marker enzymes, viz. mitochondrial succinate-cytochrome c reductase; microsomal NADPH-cytochrome c reductase and cytosolic glucose-6-phosphate dehydrogenase, increased maximally (40 to 70 percent over control) after 3 to 4 days of exposure, and remained elevated throughout the 0.8 ppM ozone exposure for 30 days. In monkeys, the observations were the same except that the magnitude of biochemical changes was relatively smaller. Exposure of animals to lower levels of ozone resulted in proportionately smaller biochemical changes in the lung, and ozone effects were detectable up to the 0.2 ppM level. While 0.1 ppM ozone exposure was ineffective, dietary deficiency of vitamin E, a natural antioxidant, increased the sensitivity of rat lungs to this concentration of ozone. The results suggest that low-level ozone exposures may cause metabolic alterations in the lung, and that dietary supplementation of vitamin E may offer protection against oxidant stress.

  2. Oscillation results for certain fractional difference equations

    Directory of Open Access Journals (Sweden)

    Zhiyun WANG

    2017-08-01

    Full Text Available Fractional calculus is a theory that studies the properties and application of arbitrary order differentiation and integration. It can describe the physical properties of some systems more accurately, and better adapt to changes in the system, playing an important role in many fields. For example, it can describe the process of tumor growth (growth stimulation and growth inhibition in biomedical science. The oscillation of solutions of two kinds of fractional difference equations is studied, mainly using the proof by contradiction, that is, assuming the equation has a nonstationary solution. For the first kind of equation, the function symbol is firstly determined, and by constructing the Riccati function, the difference is calculated. Then the condition of the function is used to satisfy the contradiction, that is, the assumption is false, which verifies the oscillation of the solution. For the second kind of equation with initial condition, the equivalent fractional sum form of the fractional difference equation are firstly proved. With considering 0<α≤1 and α>1, respectively, by using the properties of Stirling formula and factorial function, the contradictory is got through enhanced processing, namely the assuming is not established, and the sufficient condition for the bounded solutions of the fractional difference equation is obtained. The above results will optimize the relevant conclusions and enrich the relevant results. The results are applied to the specific equations, and the oscillation of the solutions of equations is proved.

    Full Text Available Background. To evaluate etiology, indications, results and complication rates associated with corneal transplantation for keratoconus.Methods. In this retrospective clinical study, 101 eyes of 79 patients had corneal transplantation. Mean age at surgery was 30.5 years. Follow up period was 2 to 25 yrs. All surgeries were performed by one surgeon. Candidate for surgery were patients who cannot tolerate contact lenses or are not adequately visually rehabilitated by them. Before surgery the best corrected visual acuity was 0.05 to 0.3 in 27%; 73% of patients had uncorrected visual acuity hand movement or counting fingers.Results. Best corrected visual acuity postoperatively was in 72% of patients 0.5 to 1.0and in 26% 0.4 to 0.1. 2% of patients had visual acuity less than 0.1. In all cases we had postkeratoplasty astigmatism of 2.5 ± 4.75Cyl with or without residual myopia. The most often postoperative complication was graft rejection (10% which was successfully treated with medications. Unsuccessfull rate was 3%.Conclusions. The improved results, low complication rate, and postoperative enhancement management indicate that corneal transplantation is a viable option in the clinical course of keratoconus. The optimal visual acuity postoperatively is achieved with contact lens, which correct postoperative astigmatism and myopia. Improvements in refractive surgery can help manage with postkeratoplasty astigmatism and myopia.

    2009-06-01

    The advantage of wrist arthroplasty remains controversial, primarily due to the high complication rate. For this reason it seems sensible to monitor the results of different types of prostheses even with small numbers of cases. We were particularly interested to see if wrist joint arthroplasty is a useful alternative for patients with rheumatoid arthritis, and which of the types we used shows the best results. In our hospital, 41 wrist joint prostheses (15 Meuli, 16 BIAX and 10 Universal 2) were implanted in 36 patients from 1992 until 2005 (follow-up 1 to 14 years, mean 5.3 years). 33 patients had rheumatic destruction of the wrist, two had osteoarthritis following fracture of the scaphoid, and one pseudarthrosis after failed arthroplasty and arthrodesis for Kienböck's disease. Mean age was 54 years, ranging from 34 to 73 years. 14 patients had had surgery on this wrist before. The patients were sent a questionnaire including the DASH score, and a clinical evaluation and X-rays were performed. 33 patients with 38 wrist arthroplasties answered the questionnaire, 34 wrist joint prosthesis of 29 patients could be evaluated. 6 prostheses had to be removed because of complications (3 arthrodeses were performed after removal, 3 prostheses were exchanged). There were 4 dislocations (3 times with the Meuli type, once with the BIAX type). There was one case of CRPS type I. But subjectively, in answering our questionnaire, 31 of 38 patients claimed to be very satisfied or satisfied with the result of the operation, only 6 were less satisfied or not satisfied at all. An improvement of pain was found by all but one patient. An increase in strength or range of movement was found more rarely. The mean postoperative DASH score was 61 points. Mean wrist joint mobility was 50 degrees for extension/flexion, and 20 degrees for radial- and ulnar abduction. The result of total wrist joint arthroplasty depends very much on a careful patient selection. A preoperative bony malposition

    Our objective was to elaborate a predictive model of bladder cancer, in an unselected clinical population submitted to cystoscopy. We recruited consecutive patients that underwent cystoscopy due to suspicion of bladder cancer or surveillance of a previously diagnosed bladder cancer. Urine cytology and a BTA-stat® (BTA) test were carried out for all patients. To avoid an assessment bias, the BTA-tests, cytologies and cystoscopies were conducted in a blinded fashion. We used logistic regression to predict cystoscopy results from cytology, BTA-test and clinical variables. From August 2011 to July 2012, we recruited 244 patients and 237 were valid for analysis. Newly diagnosed and surveillance cases were 13% and 87% respectively. Cytology and BTA-test sensitivities were 57.9% (CI 95: 42.2-72.1) and 63.2% (CI 95: 47.3-76.6) with specificities of 84.4% (CI 95: 78.7-88.8) and 82.9% (CI 95: 77.1-87.5). The predictive model included the BTA-test, cytology, time since previous tumour, and treatment with mitomicin or BGC during the last three months. The model predictive accuracy (AUC) was .85 (.78-.92), and dropped to 0.79 when excluding the BTA-test (P=.026). For the surveillance of bladder cancer, a 10% threshold on the model predicted probabilities resulted in an overall negative predictive value of 95.7%, and 95.0% in low grade tumours. In a cost containment environment, our prediction model could be used to space out cystoscopies in patients with previous, low grade tumours, resulting in a more efficient use of resources in the healthcare system.

    2013-01-01

    Background and purpose During the past 40 years, several attempts have been made with total wrist arthroplasty to avoid fusion in severely destroyed wrists. The results have often been disappointing. There is only modest clinical documentation due to the small number of patients (especially non-rheumatoid cases) and short follow-up times. Here we report a multicenter series using a third-generation implant with a minimum follow-up time of 5 years. Methods In 2012, data were retrieved from a registry of consecutive wrist operations at 7 centers with units specialized in hand surgery, between 2003 and 2007. The wrists had been reviewed annually and analysis was done on the latest follow-up data. Results 60 patients had been operated (5 bilaterally), 5 wrists had been revised, and 52 were available for follow-up (with the revised cases excluded). The pain scores, QuickDASH scores, ulnar flexion, and supination for the whole group were statistically significantly better at follow-up. There were no statistically significant differences between the rheumatoid and the non-rheumatoid patients except for motion, which was better in the non-rheumatoid group. The motion obtained depended on the preoperative motion. Implant survival was 0.9 at 5–9 years. Interpretation The clinical results in terms of pain, motion, strength, and function were similar to those in previous reports. The implant survival was 0.9 at 9 years, both in rheumatoid and non-rheumatoid cases, which is an important improvement compared to the earlier generations of total wrist arthroplasty. PMID:23848216

    The MAST (Mega-Amp Spherical Tokamak) experiment is now fully operational, producing 1MA plasmas with MW level auxiliary heating from Neutral Beam Injection and 60GHz Electron Cyclotron Resonance Heating. Central electron and ion temperatures are both of order 1keV (measured by 30-point Thomson Scattering, Neutral Particle Analyzer and Charge-Exchange spectroscopy respectively). Following boronisation, the Greenwald density limit has been exceeded in double-null divertor discharges by 50operation has been achieved in both Ohmic and NBI heated plasmas. In addition to conventional plasma induction, MAST can employ the `merging-compression' scheme (pioneered on START) producing initial spherical tokamak plasmas of up to 0.5MA without use of flux from the central solenoid. The central solenoid can then be applied to further increase the current at ramp rates of up to 13MA/s; plasma current of 1MA is reached at only one-half of the full solenoid swing. Studies of strike point power loading in both Ohmic and beam heated plasmas have confirmed the result from START that the fraction of power loading on the inboard strike point is lower than predicted from simple models. Comprehensive arrays of halo detectors indicate tolerable levels of halo currents with low asymmetries; an encouraging result for the ST concept, and providing key data to test models. Results from MAST will be used both to extend the conventional tokamak database, and to determine the potential of the ST as a route to fusion power in its own right.

    Magnetospheric Multiscale (MMS) mission will study small-scale reconnection structures and their rapid motions from closely spaced platforms using instruments capable of high angular, energy, and time resolution measurements. The Dual Electron Spectrometer (DES) of the Fast Plasma Instrument (FPI) for MMS meets these demanding requirements by acquiring the electron velocity distribution functions (VDFs) for the full sky with high-resolution angular measurements every 30 ms. This will provide unprecedented access to electron scale dynamics within the reconnection diffusion region. The DES consists of eight half-top-hat energy analyzers. Each analyzer has a 6 deg. x 11.25 deg. Full-sky coverage is achieved by electrostatically stepping the FOV of each of the eight sensors through four discrete deflection look directions. Data compression and burst memory management will provide approximately 30 minutes of high time resolution data during each orbit of the four MMS spacecraft. Each spacecraft will intelligently downlink the data sequences that contain the greatest amount of temporal structure. Here we present the results of a simulation of the DES analyzer measurements, data compression and decompression, as well as ground-based analysis using as a seed re-processed Cluster/PEACE electron measurements. The Cluster/PEACE electron measurements have been reprocessed through virtual DES analyzers with their proper geometrical, energy, and timing scale factors and re-mapped via interpolation to the DES angular and energy phase-space sampling measurements. The results of the simulated DES measurements are analyzed and the full moments of the simulated VDFs are compared with those obtained from the Cluster/PEACE spectrometer using a standard quadrature moment, a newly implemented spectral spherical harmonic method, and a singular value decomposition method. Our preliminary moment calculations show a remarkable agreement within the uncertainties of the measurements, with the

    Intestinal/multivisceral transplantation (IT/MVT) is the gold standard treatment for patients with intestinal failure and complications related to total parenteral nutrition, gastrointestinal inoperable indolent tumors, or diffuse portal trombosis. Currently, the reported 1-year patient survival rate is around 80%, similar to other solid organ abdominal transplantations. Unfortunately, the patient survival decreases after the first year with the 5-year rate not close to 70% yet. Acute cellular rejection is the main cause of graft loss. Its early diagnosis may make it possible to improve survival of retransplantations. To analyze the reported results published in the last 5 years by leading transplant centers to evaluate IT/MVT retransplantation results. We performed a literature review using PubMed focusing on multivisceral and intestinal retransplantation in articles published between 2006 and 2012. In relation to the first transplantation, we analyzed demographics, imunosuppression, rejection, infection as well as graft and patient survival rates. Two centers reported results on intestinal and multivisceral retransplantations. Mazariegos et al reported their experience with 15 intestinal retransplantations in 14 pediatric recipients. Four patients died from posttransplant lymphoperliferative disease, severe acute cellular rejection, fungal sepsis, or bleeding from a pseudoaneurysm at a mean time of 5.7 months post-transplantation. Total parenteral nutrition was weaned at a median time of 32 days. Abu-Elmaged et al reported 47 cases with a 5-year survival of 47% for all retransplant modalities. Retransplantation with liver-contained visceral allograft achieved a 5-year survival rate of 61% compared with 16% for liver-free visceral grafts. Despite those huge improvements, some transplanted patients develop severe acute cellular rejection, culminating in graft loss and retransplantation. Repots on multivisceral and intestinal retransplantation outcomes suggest that

    The underlying event activity in $pp$ collisions is measured using events with a leading charged-particle jet. The activity is measured independently in the two halves of the region transverse to the leading object, containing the maximum and minimum activities. Complementary to the underlying event analysis, the observation of long-range two-particle correlations in high energy heavy ion collisions opens opportunities to explore QCD in quark gluon plasma, the hot dense matter created in heavy ion collisions. The observation of similar correlation structures in high multiplicity $pp$ collisions suggests novel QCD effects. We present selected results of the underlying event activity and particle correlations in various collision systems.

    Full Text Available Purpose: To determine horizontal deviation type and to evaluate the correlation between deviation type/etiology and surgical results for sensory strabismus. Patients and Methods: The reports of 29 patients operated for sensory strabismus (12 female, 17 male whose mean age was 22.17±11.52 (range: 4-57 years were evaluated retrospectively. Sixteen cases (55.2% had exotropia (XT and 13 cases (44.8% had esotropia (ET. Etiologies, ages during surgeries, and preoperative/postoperative deviation amounts were noted for the total of the patients as well as for ET and XT groups separately. The results for ET and XT groups were compared statistically using t test. The mean follow-up time was 4.27±3.5 years (range: 4 months-12 years and deviation in ±10 prism diopters (PD in the last visit was considered as success. Results: Etiologies in all cases examined were as follows: anisometropia in 13 (44.8%, trauma in 10 (34.5%, congenital cataracts in 2, and congenital glaucoma, keratoconus, choroidal coloboma, and hypoplastic optic disc in one case each. The visual acuity of the squinting eyes ranged from no light perception to 0.8 logMAR. The mean preoperative deviation was 46.24±19.29 PD, and the mean postoperative deviation decreased to 9.55±11.86 PD in the last visit. When the ET and XT groups were compared, the congenital causes were more common in the ET group (30.75% compared to the XT group (6.25%, otherwise, there was no statistically significant difference in terms of mean age, preoperative and postoperative deviation amounts and follow-up time between the two groups (p>0.05. In contrast, while the surgical success rate was found to be 75.9 % for all cases and 87.5% for the XT group, it was 61.5% for the ET group. Discussion: Despite the deep amblyopia in sensory strabismus, satisfactory surgical results are achieved; nevertheless, the success may be more limited in sensory esotropia particularly due to congenital causes.

    GVNS is a well known and widely used metaheuristic for solving efficiently many NP-Hard Combinatorial Optimization problems. In this paper, the qGVNS, which is a new quantum inspired variant of GVNS, is being introduced. This variant differs in terms of the perturbation phase because it achieves the shaking moves by adopting quantum computing principles. The functionality and efficiency of qGVNS have been tested using a comparative study (compared with the equivalent GVNS results) in selected TSPLib instances, both in first and best improvement.

    We present atmospheric neutrino results from a 71 kiloton year (1140 days) exposure of the Super-Kamiokande detector. Our data are well explained by nu /sub mu / to nu /sub tau / 2-flavor oscillations. We update the 3 flavor analysis of contained events. Also we have been attempting to discriminate between the possible oscillating partners of the muon neutrino as being either the tau neutrino or the sterile neutrino. These tests use expected differences due to neutral currents and matter effects to discriminate the possibilities. We find no evidence favoring sterile neutrinos, and reject the hypothesis at 99% confidence level.

    This paper is a summary of non-accelerator neutrino physics, concentrating on the latest experimental results using atmospheric and solar neutrinos to study neutrino oscillation. Neutrino oscillation is well-established in atmospheric neutrinos and current efforts aim to better measure and understand the phenomenon. Solar neutrinos continue to present an unsolved puzzle, with the latest data from Super-Kamiokande exhibiting a large flux deficit, but no significant day-night flux difference or spectral distortion. For both atmospheric and solar neutrinos, the data prefers oscillation between active flavors ( nu /sub e/ nu /sub mu / nu /sub tau /) and disfavors a 2-flavor oscillation to nu -sterile as the primary effect.

    2011-09-30

    Volume-scanning elastic has been investigated as a means to derive 3D dynamic wind fields for characterization and monitoring of wind energy sites. An eye-safe volume-scanning lidar system was adapted for volume imaging of aerosol concentrations out to a range of 300m. Reformatting of the lidar data as dynamic volume images was successfully demonstrated. A practical method for deriving 3D wind fields from dynamic volume imagery was identified and demonstrated. However, the natural phenomenology was found to provide insufficient aerosol features for reliable wind sensing. The results of this study may be applicable to wind field measurement using injected aerosol tracers.

    Recent low pressure continuous low plasma discharge simulations of the auroral electron driven organic chemistry in Titan's mesosphere are reviewed. These simulations yielded results in good accord with Voyager observations of gas phase organic species. Optical constants of the brownish solid tholins produced in similar experiments are in good accord with Voyager observations of the Titan haze. Titan tholins are rich in prebiotic organic constituents; the Huygens entry probe may shed light on some of the processes that led to the origin of life on Earth.

    Objective This study assessed primary urethral reconstruction results in patients with a penile fracture. Materials and methods Between January 2005 and April 2016, patients who underwent primary urethral reconstruction due to penile fracture were called for a follow-up. Epidemiological and clinical presentation data and operative findings were reviewed retrospectively. Partial urethral lesions were primarily treated with interrupted absorbable sutures over urethral catheter. In cases of complete urethral lesion, tension-free end-to-end anastomosis was performed. From the third month after surgery, all patients were interviewed using the International Prostate Symptom Score questionnaire and uroflowmetry. Retrograde urethrocystography was used in patients with urinary symptoms or altered uroflowmetry to rule out or confirm urethral stenosis. Results Of 175 patients with penile fractures, 27 (15.4%) had associated urethral injury. All patients were diagnosed with penile fracture by means of clinical history and physical examination. No subsequent examinations were conducted. Ages varied from 30 years to 58 years old (mean 39.2 years). All fractures resulted from sexual activity. Reported sexual positions were 'doggy style' position in eight cases (61.5%) and with the 'man on top' in five cases (38.4%). Ten patients (76.9%) experienced haematuria, ten (76.9%) had urethral bleeding and four (30.7%) suffered urinary retention. Unilateral and bilateral injury of the corpus cavernosum was observed in four (30.7%) and nine (69.2%) patients, respectively; partial injury was found in nine cases (69.3%) and complete urethral injury was noticed in four cases (30.7%). All cases of complete urethral injury were associated with bilateral lesion of the corpus cavernosum. Six patients who had uroflowmetry with maximum urinary flow rate below 15 ml/s and/or had IPSS above 7 underwent retrograde urethrocystogram, and this was normal in all cases, excluding the possibility of

  15. QCD Results from ATLAS and CMS

    The ATLAS and CMS collaborations have performed a wide range of studies of QCD phenomena, from soft particle to hard photon and jet production. Recent soft-­QCD measurements include studies of the underlying event, double parton interactions and vector meson production. Differential measurements of inclusive and dijet production provide stringent tests of high­-order QCD predictions and provide input for the determination of parton density functions. Measurements of isolated, inclusive and di­-photon cross sections for high-pT photons test various theoretical predictions and further constrain PDFs. An overview of these results is given.

    Since December 2010, the CMD-3 detector has collected data at the electron-positron collider VEPP- 2000. The sample of the accumulated data corresponds to about 60 pb-1 of integrated luminosity in the c.m. energy from 0.32 up to 2 GeV. Preliminary results of the analysis of various processes e+e- annihilation to hadrons are presented. It is shown the processes with multihadron events have several intermediate states which must be taken into account to correctly describe the angular and invariant mass distributions as well as cross section dependence versus energy.

    It is expected that a radio signal in the microwave range is produced in the atmosphere due to molecular bremsstrahlung initiated by extensive air showers. The CROME (Cosmic-Ray Observation via Microwave Emission) experiment was built to search for this microwave signal. Radiation from the atmosphere is monitored in the extended C band (3.4--4.2 GHz) in coincidence with showers detected by the KASCADE-Grande experiment. The detector setup consists of several parabolic antennas and fast read-out electronics. The sensitivity of the detector has been measured with different methods. First results after half a year of data taking are presented.

    Juno is the first mission to investigate Jupiter using a close polar orbit. The Juno science goals include the study of Jupiter interior composition and structure, deep atmosphere and its polar magnetosphere. All orbits have peri-jove at approximately 5000 km above Jupiter's visible cloud tops. The payload consists of a set of microwave antennas for deep sounding, magnetometers, gravity radio science, low and high energy charged particle detectors, plasma wave antennas, ultraviolet imaging spectrograph, infrared imager and spectrometer and a visible camera. The Juno mission design, an overview of the early science results from Juno, and a description of the collaborative Earth based campaign will be presented.

    Geological Survey of Finland carried out its airborne gamma ray measurement flight for RESUME95 exercise at the planning stage of the exercise; actually 9 weeks beforehand. Although some of the flight parameters (line spacing 100 metres and altitude 30 - 40 metres) differ from those used by the other teams during RESUME95, the results obtained by GSF are in line with the others. Mapping Cs-137 fallout at Area II gave mean value of 83.8 kBq/m{sup 2} and maximum of 137 kBq/m{sup 2}. (au).
