    Full Text Available El objetivo de esta investigación fue conocer aspectos poblacionales, biológicos y ecológicos de las tortugas carey (Eretmochelys imbricata presentes en el Pacífico sur de Colombia (Departamento del Cauca, para esto se tomó información de morfometría, se revisó el estado de salud de los individuos y se tomaron muestras de sangre para valoración de química sanguínea. Durante siete meses de muestreo se capturaron 25 tortugas carey (16 individuos diferentes en los arrecifes del Parque Nacional Natural Gorgona, con un porcentaje de recaptura del 46 %. Aunque no se notaron problemas evidentes de salud, la mayoría de animales presentaron gran parte del caparazón cubierto de algas filamentosas y algunos epibiontes sobre el plastrón y el caparazón. La Longitud Curva Caparazón (LCC mostró una mayor proporción de individuos con tallas entre 37 y 45 cm de longitud (prom. 42,3 cm; min. 37,5 cm; max. 58 cm. Por medio de la prueba de Mann Whitney U, se comparó la LCC de los 16 individuos diferentes capturados en el PNN Gorgona, con 11 individuos capturados en la zona del litoral del Departamento del Cauca, encontrándose diferencias significativas entre estos dos grupos, donde los animales presentes en el PNN Gorgona fueron de mayor talla que los presentes en el continente (Z = -2,59; p = 0,007. Los valores de ácido úrico se encontraron por encima de los valores de referencia.

    Full Text Available El Caribe costarricense es importante como sitio de alimentación, copulación, anidación y desove de las tortugas marinas, por lo que el presente trabajo pretendió actualizar el patrón de anidación en las tortugas marinas Dermochelys coriacea y Eretmochelys imbricata en el sector Gandoca, del Refugio Nacional de Vida Silvestre Gandoca Manzanillo, Limón, Costa Rica, para proponer medidas de manejo. Se realizaron recorridos nocturnos entre las 8:00 p. m. y 4:00 a. m., la playa se dividió en cinco sectores, en estos se realizaron observaciones directas y de rastros, de las tortugas que elaboraron el nido, entre febrero y agosto del 2011 y 2012. Se registraron tres especies de tortugas marinas, Dermochelys coriacea, Eretmochelys imbricata y Chelonia mydas. La anidación de tortugas baula tuvo su punto máximo entre marzo y julio; por su parte, las carey, entre mayo y junio (2011, y junio hasta agosto en el 2012. Se observó preferencia en la posición de la playa utilizada para construir sus nidos; la baula utiliza principalmente la parte media, mientras que la carey utilizó mayormente la parte baja para anidar (t = 17.2525. Se observó que la baula utilizó frecuentemente el sector C; sin embargo, no se encontraron diferencias en el uso de los sectores. Se concluye que ambas especies tienen preferencias en la selección de la zona de playa en que anidan; la carey en la parte baja cerca de la línea de costa y la baula en la parte media. Además, las tortugas baula utilizan indistintamente los diferentes sectores de la playa estudiada.

    Full Text Available The objective of this research was to determine biological and ecological population characteristics of the hawksbill turtle (Eretmochelys imbricata found in the southern Colombian Pacific department of Cauca. Morphometric measurements were recorded, the health status of individuals was reviewed, and blood samples were taken for a biochemistry assessment. During the seven months of the investigation, 25 hawksbill turtles were caught (16 different individuals on the reefs of Gorgona Natural National Park. Forty-six percent of the total numbers of turtles assessed were recaptured during the study period. While no obvious health problems were noted, most animals possessed epibionts and filamentous algae covering the carapace, some parts of the limbs, as well as on their neck. Curved carapace length (CCL showed the highest proportion of individuals were between 37 and 45 cm. Sixteen individuals captured in Gorgona Natural National Park were compared with 11 individuals captured in the coastal zone of the department of Cauca. Using the Mann-Whitney U test, a significant difference in CCL was found between these two groups; the animals from Gorgona National Park were larger than those present on the coast of the mainland (Z = -2.59, p = 0.007. Uric acid concentrations were found to be higher than previously referenced values. ESTUDIO POBLACIONAL DE LA TORTUGA CAREY Eretmochelys imbricata (CHELONIIDAE EN EL PACÍFICO SUR DE COLOMBIAEl objetivo de esta investigación fue conocer aspectos poblacionales, biológicos y ecológicos de las tortugas carey (Eretmochelys imbricata presentes en el Pacífico sur de Colombia (Departamento del Cauca, para esto se tomó información de morfometría, se revisó el estado de salud de los individuos y  se tomaron muestras de sangre para valoración de química sanguínea.

    In recent years, the use of blood chemistry as a diagnostic tool for sea turtles has been demonstrated, but much of its effectiveness relies on reference intervals. The first comprehensive blood chemistry values for healthy wild hawksbill (Eretmochelys imbricata) sea turtles are presented. Nineteen blood chemistry analytes and packed cell volume were analysed for 40 clinically healthy juvenile hawksbill sea turtles captured from a rocky reef habitat in northern Australia. We used four statistical approaches to calculate reference intervals and to investigate their use with non-normal distributions and small sample sizes, and to compare upper and lower limits between methods. Eleven analytes were correlated with curved carapace length indicating that body size should be considered when designing future studies and interpreting analyte values.

    The hawksbill sea turtle (Eretmochelys imbricata) is a critically endangered species at a risk of extinction. Preservation of the genomic and cellular information of endangered animals is important for future genetic and biological studies. Here, we report the efficient establishment of primary fibroblast cultures from skin tissue of the hawksbill sea turtle. We succeeded in establishing 19 primary cultures from 20 hawksbill sea turtle individuals (a success rate of 95%). These cells exhibited a fibroblast-like morphology and grew optimally at a temperature of 26°C, but experienced a loss of viability when cultured at 37°C. Chromosomal analysis using the primary cells derived here revealed that hawksbill sea turtles have a 2n = 56 karyotype. Furthermore, we showed that our primary cell cultures are free of several fish-related viruses, and this finding is important for preservation purposes. To our knowledge, this report is the first to describe primary cell cultures established from normal tissues of the hawksbill sea turtle. The results will contribute to the preservation of biodiversity, especially for the sea turtles that are critically endangered owing to human activities.

    Hybridization among sea turtle species has been widely reported in the Atlantic Ocean, but their detection in the Pacific Ocean is limited to just two individual hybrid turtles, in the northern hemisphere. Herein, we report, for the first time in the southeast Pacific, the presence of a sea turtle hybrid between the green turtle Chelonia mydas and the hawksbill turtle Eretmochelys imbricata. This juvenile sea turtle was captured in northern Peru (4°13'S; 81°10'W) on the 5(th) of January, 2014. The individual exhibited morphological characteristics of C. mydas such as dark green coloration, single pair of pre-frontal scales, four post-orbital scales, and mandibular median ridge, while the presence of two claws in each frontal flipper, and elongated snout resembled the features of E. imbricata. In addition to morphological evidence, we confirmed the hybrid status of this animal using genetic analysis of the mitochondrial gene cytochrome oxidase I, which revealed that the hybrid individual resulted from the cross between a female E. imbricata and a male C. mydas. Our report extends the geographical range of occurrence of hybrid sea turtles in the Pacific Ocean, and is a significant observation of interspecific breeding between one of the world's most critically endangered populations of sea turtles, the east Pacific E. imbricata, and a relatively healthy population, the east Pacific C. mydas.

    Damazo, Lindsey Renee Eggers

    The hawksbill sea turtle (Eretmochelys imbricata) has a circumtropical distribution and plays an important role in maintaining the health of coral reefs. Unfortunately, hawksbill populations have been decimated, and estimated numbers in the Caribbean are less than 10% of populations a century ago. The hawksbill is considered Critically Endangered, and researchers are coordinating worldwide efforts to protect this species. One country where we lack knowledge regarding hawksbills is Honduras. This study aimed to increase our understanding of hawksbill nesting ecology in Caribbean Honduras. Characteristics of hawksbill nesting activity and a nesting beach on the island of Utila were elucidated using satellite telemetry, beach profiling, vegetation surveys, beach monitoring, and nest temperature profiles. We affixed satellite transmitters to two nesting hawksbills, and found the turtles migrated to different countries. One turtle traveled 403 km to a bay in Mexico, and the other traveled 181 km to a Marine Protected Area off Belize. This study presents the first description of hawksbill migration routes from Honduras, facilitating protection efforts for turtles that traverse international waters. To investigate nesting beach and turtle characteristics, we conducted beach monitoring during the 2012 nesting season. Nesting turtle carapace sizes were similar to worldwide values, but hatchlings were heavier. To measure nest temperatures, we placed thermocouple data loggers in four nests and four pseudo-nests. Data suggested metabolic heating may be maintaining nest temperatures above the pivotal temperature. However, large temperature fluctuations corresponding to rainfall from Hurricane Ernesto (as determined using a time series cross-correlation analysis) make it difficult to predict sex ratios, and underscore the impact stochastic events can have on nest temperatures. We created topographic and substrate profiles of the beach, and found it was 475 m long, yet hawksbills

    Full Text Available The coast of Northern Andhra Pradesh has predominantly rocky and sandy shores with sporadic nesting sites of olive ridley turtles Lepidochelys olivacea. However, there have been rare sightings of hawksbill turtles Eretmochelys imbricata along this coast in the past couple of decades and their nesting is seldom observed. Carcasses of two adult hawksbill turtles were observed on 29/12/2010 and 07/03/2011 along the coast of Visakhapatnam in Northern Andhra Pradesh, India. These sightings of dead hawksbill turtles along this coast come recently after a long gap of several years and emphasize on the need to carry out surveys in the area for devising effective long term conservation management strategies.

    Chromium is both a global marine pollutant and a known human health hazard. In this study, we compare the cytotoxicity and genotoxicity of both soluble and particulate chromate in human and hawksbill sea turtle (Eretmochelys imbricata) skin fibroblasts. Our data show that both soluble and particulate Cr(VI) induce concentration-dependent increases in cytotoxicity, genotoxicity, and intracellular Cr ion concentrations in both human and hawksbill sea turtle fibroblasts. Based on administered concentration, particulate and soluble Cr(VI) were more cytotoxic and clastogenic to human cells than sea turtle cells. When the analysis was based on the intracellular concentration of Cr, the data showed that the response of both species was similar. The one exception was the cytotoxicity of intracellular Cr ions from soluble Cr(VI), which caused more cytotoxicity in sea turtle cells (LC50=271μM) than that of human cells (LC50=471μM), but its clastogenicity was similar between the two species. Thus, adjusting for differences in uptake indicated that the explanation for the difference in potency was mostly due to uptake rather than differently affected mechanisms. Overall these data indicate that sea turtles may be a useful sentinel for human health responses to marine pollution.

    Concentrations of elements (As, Al, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, Sb, Se, Sr, V, Zn) were determined in liver, kidneys and bones of Eretmochelys imbricata and Chelonia mydas specimens found stranded along the northern coast of Bahia, Brazil. Results showed that the concentrations of Cd, Cu, Ni and Zn in the liver and kidneys of juvenile C. mydas were the highest found in Brazil. We also observed a significant difference (p<0.05) on the bioaccumulation of trace elements between the two species: Al, Co, Mo, Na and Se in the liver; Al, Cr, Cu, K, Mo, Ni, Pb, Sr and V in the kidneys; and Al, Ba, Ca, Cd, Mn, Ni, Pb, Se, Sr and V in the bones. This study represents the first report on the distribution and concentration of trace elements in E. imbricata in the Brazilian coast.

    Full Text Available Habitat bioaugmentation and introduction of protective microbiota have been proposed as potential conservation strategies to rescue endangered mammals and amphibians from emerging diseases. For both strategies, insight into the microbiomes of the endangered species and their habitats is essential. Here, we sampled nests of the endangered sea turtle species Eretmochelys imbricata that were infected with the fungal pathogen Fusarium falciforme. Metagenomic analysis of the bacterial communities associated with the shells of the sea turtle eggs revealed approximately 16,664 operational taxonomic units, with Proteobacteria, Actinobacteria, Firmicutes and Bacteroidetes as the most dominant phyla. Subsequent isolation of Actinobacteria from the eggshells led to the identification of several genera (Streptomyces, Amycolaptosis, Micromomospora Plantactinospora and Solwaraspora that inhibit hyphal growth of the pathogen F. falciforme. These bacterial genera constitute a first set of microbial indicators to evaluate the potential role of microbiota in conservation of endangered sea turtle species.

    Gonad maturity is usually evaluated through macroscopic analysis of the gonads. In sea turtles, the maturation stages are associated with body size, depending on the studied marine stock. Fishermen classify turtles bigger than 65.0 cm as sexually mature. If they have secondary sex characters they are recorded as breeding males. We compared body size with macroscopic and microscopic gonad characteristics in two Cuban turtles. Eighteen individuals of C. mydas and twenty of E. imbricata was obtained from the legal fishery stock of Jardines del Rey Archipelago (Cuba), from October 2005 and 2006. In males, breeding condition (maximum spermiogenesis) was checked by histological analysis of the testes. In females, sexual maturity was identified by the presence of vitellogenic follicles or ovarian corpora. Most males were immature (C. mydas: 79.0 cm; E. imbricata: 73.1+/-4.9 cm, n=3) and lacked secondary sex characters. Some E. imbricata without a developed penis were in spermatogenic stages II to IV (i.e. pubescent). Most females were immature (C. mydas: 79.6+/-7.7 cm, n=17; E. imbricata: 69.0+/-7.1 cm, n=16; i.e.prepubescent and pubescent. The prepubescent females had ovaries with previtellogenic follicles near 1.0 mm in a compact and yellowish stroma. The pubescent females had ovaries with previtellogenic follicles between 2.0 and 3.0 mm. The stroma was more loosened and irrigated than in prepubescent turtles. The finding of spermatogenic activity in pubescent males indicates asynchrony between testicular and penial development in E. imbricata. The current phenotypical approach used by fishermen is not enough to determine sexual maturation in these turtles. The minimal size tentatively should be changed to: C. mydas: above 93.0 cm and E. imbricata above 79.0 cm.

    Data on the impact of environmental pollution on the homeostasis of sea turtles remains scarce, particularly in the Southern Gulf of Mexico. As many municipalities along the coastline of the Yucatan Peninsula do not rely on a waste treatment plant, these organisms could be particularly vulnerable. We searched for relationships between the presence of organochlorine pesticides (OCP) and the level of several oxidative and pollutant stress indicators of the hawksbill sea turtle (Eretmochelys imbricata) during the 2010 nesting season at Punta Xen (Campeche, Mexico). Of the 30 sampled sea turtles, endosulfans, aldrin related (aldrin, endrin, dieldrin, endrin ketone, endrin aldehyde) and dichlorodiphenyldichloroethylene (DDT) families were detected in 17, 21 and 26, respectively. Significant correlation existed between the size of sea turtles with the concentration of methoxychlor, cholinesterase activity in plasma and heptachlors family, and catalase activity and hexachlorohexane family. Cholinesterase activity in washed erythrocytes and lipid peroxidation were positively correlated with glutathione reductase activity. Antioxidant enzyme actions seem adequate as no lipids damages were correlated with any OCPs. Future studies are necessary to evaluate the effect of OCPs on males of the area due to the significant detection of methoxychlor, which target endocrine functioning and increases its concentration with sea turtles size.

    Glutathione s-transferases (GST) play a critical role in the detoxification of exogenous and endogenous electrophiles, as well as the products of oxidative stress. As compared to mammals, GST activity has not been extensively characterized in reptiles. Throughout the globe, most sea turtle populations face the risk of extinction. Of the natural and anthropogenic threats to sea turtles, the effects of environmental chemicals and related biochemical mechanisms, such as GST catalyzed detoxification, are probably the least understood. In the present study, GST activity was characterized in four species of sea turtles with varied life histories and feeding strategies: loggerhead (Caretta caretta), green (Chelonia mydas), olive ridley (Lepidochelys olivacea), and hawksbill (Eretmochelys imbricata). Although similar GST kinetics was observed between species, rates of catalytic activities using class-specific substrates show inter- and intra-species variation. GST from the spongivorous hawksbill sea turtle shows 3-4.5 fold higher activity with the substrate 4-nitrobenzylchloride than the other 3 species. GST from the herbivorous green sea turtle shows 3 fold higher activity with the substrate ethacrynic acid than the carnivorous olive ridley sea turtle. The results of this study may provide insight into differences in biotransformation potential in the four species of sea turtles and the possible health impacts of contaminant biotransformation by sea turtles.

    Mitochondrial DNA sequence polymorphisms and patterns of genetic diversity represent the genealogy and relative impacts of historical, geographic, and demographic events on populations. In this study, historical patterns of population dynamics and differentiation in hawksbill (Eretmochelys imbricata) and green turtles (Chelonia mydas) in the Pacific were estimated from feeding populations in the Yaeyama Islands, Japan. Phylogenetic relationships of the haplotypes indicated that hawksbill and green turtles in the Pacific probably underwent very similar patterns and processes of population dynamics over the last million years, with population subdivision during the early Pleistocene and population expansion after the last glacial maximum. These significant contemporary historical events were suggested to have been caused by climatic and sea-level fluctuations. On the other hand, comparing our results to long-term population dynamics in the Atlantic, population subdivisions during the early Pleistocene were specific to Pacific hawksbill and green turtles. Therefore, regional differences in historical population dynamics are suggested. Despite limited sampling locations, these results are the first step in estimating the historical trends in Pacific sea turtles by using phylogenetics and population genetics.

    Despite the current environmental concern regarding the risk posed by contamination in marine ecosystems, the concentrations of pollutants in sea turtles have not been thoroughly elucidated. In the current study, we determined the concentrations of 18 organochlorine pesticides (OCPs), 18 polychlorinated biphenyls (PCBs), 16 polycyclic aromatic hydrocarbons (PAHs) and 11 inorganic elements (Cu, Mn, Pb, Zn, Cd, Ni, Cr, As, Al, Hg and Se) for the first time in two sea turtle species (Chelonia mydas and Eretmochelys imbricata). Only five of the 18 analyzed OCPs were detected in both species. The average total OCP concentration was higher in green turtles than in hawksbills (0.33 ng/ml versus 0.20 ng/ml). Higher concentrations of individual congeners and total PCBs were also detected in green turtles than in hawksbills (∑PCBs=0.73ng/ml versus 0.19 ng/ml), and different PCB contamination profiles were observed in these two species. Concerning PAHs, we also observed a different contamination profile and higher levels of contamination in green turtles (∑PAHs=12.06 ng/ml versus 2.95 ng/ml). Di- and tri-cyclic PAHs were predominant in both populations, suggesting a petrogenic origin, rather than urban sources of PAHs. Additionally, all of the samples exhibited detectable levels of the 11 inorganic elements. In this case, we also observed relevant differences between both species. Thus, Zn was the most abundant inorganic element in hawksbills (an essential inorganic element), whereas Ni, a well-known toxicant, was the most abundant inorganic element in green turtles. The presence of contaminants is greater in green turtles relative to hawksbill turtles, suggesting a greater exposure to hazardous chemical contaminants for green turtles. These results provide baseline data for these species that can serve for future monitoring purposes outlined in the EU's Marine Strategy Framework Directive.

    2004-07-01

    Tinea imbricata (TI) or Tokelau is a superficial mycosis caused by Trichophyton concentricum, an anthropophilic dermatophyte. It is endemic in some islands of the South Pacific (Polynesia), South-East Asia, Central and South America, and Mexico, and is most often seen in individuals living in primitive and isolated conditions. The skin lesions are characteristically concentric and lamellar (imbricata: in Latin, tiled) plaques of scale. Predisposing conditions include humidity, inheritance, and immunologic factors. The diagnosis is usually made on clinical grounds, supported by skin scrapings and culture. Tokelau is a chronic and highly relapsing disease and, although no first-line treatment exists, best results are obtained with oral griseofulvin and terbinafine and a topical combination of keratolytic ointments, such as Whitfield's. TI is a disease model that allows the correlation of a series of environmental, genetic, immunologic, and therapeutic conditions.

  5. Congratulations to Carey King

    Hall, Charles A. S.

    2012-03-01

    I first came across Carey King when, out of the blue, he invited me to a special session of the annual meeting of the American Association for the Advancement of Science (the largest and most prestigious US scientific meeting) where he was developing a special session on energy return on investment (EROI). At that meeting and since, I have found Carey to be a refreshing new colleague, extremely intelligent, very knowledgeable about many diverse aspects of energy and other things, able to take criticism and to dish it out, and very ambitious, which is mostly a good thing. He is becoming a leader in thinking about EROI and its implications, and I am delighted to see him honored by Environmental Research Letters. This is important because in the US, there is little insight about energy or, especially, its potential physical limitations except when gas prices increase. There is also little awareness of the very strong historical connection in both the US and the world between increased affluence and increased use of energy, especially petroleum. It is not understood by all that many of the economic problems we have now (such as the budgetary problems faced by most of our State governments, pension plans and universities) have substantial origin in the fact that oil and other energy production no longer increase reliably year after year, as they once did (Murphy and Hall 2011). Many economists have argued in the past that energy is not important because it constituted only 5 per cent or so of GDP, or because they believe that market forces and innovations will substitute for any shortage (e.g. Barnett and Morse 1963, Passell et al 1972, Solow 1974, Denison 1989). One problem with that view is that if you remove that five per cent the economy comes to a dead stop, as Cuba found out in 1989 when Russia removed its oil subsidy. Additionally if that five per cent goes up to 10 or 15 per cent, as it did in the early 1980s, and again in 2008, recession steps in (Murphy and

  9. Genetic structure and natal origins of immature hawksbill turtles (Eretmochelys imbricata in Brazilian waters.

    Directory of Open Access Journals (Sweden)

    Maira C Proietti

    Full Text Available Understanding the connections between sea turtle populations is fundamental for their effective conservation. Brazil hosts important hawksbill feeding areas, but few studies have focused on how they connect with nesting populations in the Atlantic. Here, we (1 characterized mitochondrial DNA control region haplotypes of immature hawksbills feeding along the coast of Brazil (five areas ranging from equatorial to temperate latitudes, 157 skin samples, (2 analyzed genetic structure among Atlantic hawksbill feeding populations, and (3 inferred natal origins of hawksbills in Brazilian waters using genetic, oceanographic, and population size information. We report ten haplotypes for the sampled Brazilian sites, most of which were previously observed at other Atlantic feeding grounds and rookeries. Genetic profiles of Brazilian feeding areas were significantly different from those in other regions (Caribbean and Africa, and a significant structure was observed between Brazilian feeding grounds grouped into areas influenced by the South Equatorial/North Brazil Current and those influenced by the Brazil Current. Our genetic analysis estimates that the studied Brazilian feeding aggregations are mostly composed of animals originating from the domestic rookeries Bahia and Pipa, but some contributions from African and Caribbean rookeries were also observed. Oceanographic data corroborated the local origins, but showed higher connection with West Africa and none with the Caribbean. High correlation was observed between origins estimated through genetics/rookery size and oceanographic/rookery size data, demonstrating that ocean currents and population sizes influence haplotype distribution of Brazil's hawksbill populations. The information presented here highlights the importance of national conservation strategies and international cooperation for the recovery of endangered hawksbill turtle populations.

  10. ACCURACY ANALYSIS FOR QUASI-CAREY ELEMENT

    In this paper, a new triangular element (Quasi-Carey element) is constructed by the idea of Specht element. It is shown that this Quasi-Carey element possesses a very special property, i.e.,the consistency error is of order O(h2), one order higher than its interpolation error when the exact solution belongs to Ha(Ω). However, the interpolation error and consistency error of Carey element are of order O(h). It seems that the above special property has never been seen for other triangular elements for the second order problems.

  11. Update on the Toriello-Carey syndrome.

    Science.gov (United States)

    Toriello, Helga V; Colley, Chelsey; Bamshad, Michael

    2016-10-01

    Toriello and Carey described a provisionally-unique syndrome comprised of agenesis of the corpus callosum, Pierre Robin anomaly, and a characteristic facial phenotype. Because the condition affected siblings, this entity was postulated to be an autosomal recessive multiple anomaly syndrome. Several patients were subsequently reported, and over time, it became apparent that the Toriello-Carey syndrome was etiologically heterogeneous. Based on previous reports, it is estimated that at least 20% of patients with a clinical diagnosis of Toriello-Carey syndrome have a chromosomal anomaly as the basis of the phenotype. However, no basis for the non-chromosomal cases has been found. This review summarizes the literature to date and provides speculation regarding the possible explanations for failing to find the cause of Toriello-Carey syndrome. © 2016 Wiley Periodicals, Inc.

    In Pronocephaloidea, the spermatozoa of only two species have been studied today. Because of this, we present in this work data concerning to a third specie, Pleurogonius truncatus Prudhoe, 1944. The mature spermatozoon of P. truncatus possesses two axonemes with the 9+"1" pattern typical of Trepaxonemata, mitochondrion, nucleus, parallel cortical microtubules, spinelike bodies, cytoplasmic expansion and an external ornamentation of the plasma membrane. A particularity of the spermatozoon of P. truncatus is in the ultrastructure of the anterior spermatozoon extremity with only cortical microtubules and ornamentation of the plasma membrane. This type of anterior extremity has never been described until today in Pronocephaloidea. On the other hand, the ultrastructure of the posterior extremity of the spermatozoon confirms that already described in Pronocephalidae.

    Concentrations of total arsenic (As) and individual compounds were determined in green and hawksbill turtles from Ishigaki Island, Japan. In both species, total As concentrations were highest in muscle among the tissues. Arsenobetaine was a major compound in most tissues of both turtles. High concentrations of trimethylarsine oxide were detected in hawksbill turtles. A significant negative correlation between standard carapace length (SCL), an indicator of age, and total As levels in green turtles was found. In contrast, the levels increased with SCL of hawksbill turtles. Shifts in feeding habitats with growth may account for such a growth-dependent accumulation of As. Although concentrations of As in marine sponges, the major food of hawksbill turtles are not high compared to those in algae eaten by green turtles, As concentrations in hawksbill turtles were higher than those in green turtles, indicating that hawksbill turtles may have a specific accumulation mechanism for As. - Green turtles and hawksbill turtles have specific accumulation features of arsenic.

    2005-05-01

    In August 2002, the Habitat Evaluation Procedure (HEP) was used to determine baseline habitat suitability on the Carey Creek property, an acquisition completed by the Kalispel Tribe of Indians in December 2001. Evaluation species and appropriate models include bald eagle, black-capped chickadee, Canada goose, mallard, yellow warbler, and white-tailed deer. Habitat Suitability Index (HSI) values were visually estimated and agreed upon by all HEP team members. The Carey Creek Project provides a total of 172.95 Habitat Units (HUs) for the species evaluated. Conifer forest habitat provides 4.91 HUs for bald eagle, black-capped chickadee, and white-tailed deer. Forested wetlands provide 52.68 HUs for bald eagle, black-capped chickadee, mallard, and white-tailed deer. Scrub-shrub wetlands provide 2.82 HUs for mallard, yellow warbler and white-tailed deer. Wet meadow and grassland meadow provide 98.13 HUs for mallard and Canada goose. Emergent wetlands provide 11.53 HUs for mallard, muskrat, and Canada goose. Open water provides 2.88 HUs for Canada goose, mallard, and muskrat. The objective of using HEP at the Carey Creek Project and other protected properties is to document the quality and quantity of available habitat for selected wildlife species. In this way, HEP provides information on the relative value of the same area at future points in time so that the effect of management activities on wildlife habitat can be quantified. When combined with other tools, the baseline HEP will be used to determine the most effective on-site management, restoration, and enhancement actions to increase habitat suitability for targeted species. The same process will be replicated every five years to quantitatively evaluate the effectiveness of management strategies in improving and maintaining habitat conditions while providing additional crediting to BPA for enhanced habitat values.

    The aim of this study was to evaluate the reliability of direct determination of trace and major element concentrations in plasma samples from wild (six hawksbill, nine green, and nine loggerhead) and captive sea turtles (25 howksbill, five green, and three loggerhead) in Okinawa, Japan. The particle induced X-ray emission method allowed detection of 23 trace and major elements (Al, As, Br, Ca, Cl, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Ni, P, Pb, S, Se, Si, Sr, Ti, Y, and Zn). The wild sea turtles were found to have high concentrations of As and Pb in plasma compared with captive, but there were no significant changes in the Al and Hg concentrations. Loggerhead sea turtles were found to have significantly higher accumulation of As and Pb in plasma in comparison to other species. These findings may be useful when adjusting environmental and species-related factors in severely polluted marine ecosystems. Our results indicate that measuring the plasma As and Pb concentrations in wild sea turtles might be of help to assess the level of pollution in marine ecosystems, keeping in mind that loggerhead sea turtles had been shown to have higher levels of As and Pb in plasma.

    Organochlorine pesticides and PCB (POPs) concentrations were determined in the blood and eggs of green and hawksbill turtles. We compared concentrations between species, analyzed the relationship between turtle size and the POPs concentrations and the relationship between the concentrations in the blood of the nesting turtles and their eggs. We expected higher concentrations in the hawksbill turtle because of its higher trophic level, but concentrations were not higher in all the cases. Significant differences were found in δ-HCH blood concentrations. Lindane, heptachlor epoxide and PCB 101 concentrations were significantly higher in the hawksbill eggs. The relationship between the size of the turtles and the POP concentrations in the eggs of the hawksbills showed a negative correlation. No correlation was found between the size of the female and concentrations in the blood. In eggs, only the hawksbill turtles exhibited negative correlation in the concentration of mirex and PCB 44 and size.

    Toriello-Carey syndrome is rare condition characterized by agenesis of the corpus callosum, the Pierre Robin sequence, and facial anomalies such as telecanthus, short palpebral fissures, and a small nose with anteverted nares [Toriello and Carey, 1988]. In addition, tracheal and laryngeal anomalies are common complications in patients with Toriello-Carey syndrome, and these anomalies can lead to death [Kataoka et al., 2003]. Congenital tracheal stenosis is a life-threatening condition with high mortality. Even if surgery is successful, several serious complications can result in a high risk of mortality. We describe a case of a Japanese boy with Toriello-Carey syndrome who had severe congenital tracheal stenosis, in whom surgical tracheal plasty was avoided because of adequate respiratory care, allowing the patient to be alive at 18 months of age.

    2013-01-01

    We compare morphological characteristics of male and female Barisia imbricata, Mexican alligator lizards, and find that mass, head length, coloration, incidence of scars from conspecifics, tail loss, and frequency of bearing the color/pattern of the opposite sex are all sexually dimorphic traits. Overall size (measured as snout–vent length), on the other hand, is not different between the two sexes. We use data on bite scar frequency and fecundity to evaluate competing hypotheses regarding the selective forces driving these patterns. We contend that sexual selection, acting through male-male competition, may favor larger mass and head size in males, whereas large females are likely favored by natural selection for greater fecundity. In addition, the frequency of opposite-sex patterning in males versus females may indicate that the costs of agonistic interactions among males are severe enough to allow for an alternative mating strategy. Finally, we discuss how sexual and natural selective forces may interact to drive or mask the evolution of sexually dimorphic traits. PMID:23467394

    Objective:To study the spine structure of stingray Himantura imbricata (H. imbricata) and to evaluate the anticoagulant properties of the spine extract obtained through various solvents extracts followed by antibacterial activity against human pathogens. Methods:Spines of H. imbricata were collected from Nagappattinam coast, Tamil Nadu, India and their spines were observed under the light microscope. The grounded spines were subjected to extraction of metabolites using methanol, ethanol, chloroform and acetone. Antibacterial activity was evaluated by disc diffusion technique against 10 human pathogens. Similarly, anticoagulant activity was also assessed by following United States Pharmacopeia method. Results:Light microscopic observation of spine revealed that the venom apparatus of the stingray H. imbricata consisted of two to three spines, glandular tissue and a sheath. The spine extract showed potent antibacterial activity against all tested pathogen. Maximum activity (14 mm) was found against Staphylococcus aureus. Crude extract showed 91.50 USP units/mg of anticoagulant activity. Conclusions: Microscopic observations gave new insight about the spine structure of the stingray. The spine extracts of H. imbricate showed potent activity against human pathogens revealed by the good zone of inhibition. Chloroform extracts conferred the most prominent antibacterial activity. The anticoagulant activity was also comparable with that of standard heparin.

    Objective: To investigate the in vitro antioxidant and antiproliferative activity of rhizome extracts of Rhodiola imbricata (R. imbricata) in HT-29 human colon cancer cell line. Methods: The successively extracted rhizome of R. imbricata using various solvents was analyzed for their total phenolics, tannins and flavonoid contents. In vitro antioxidant activity was evaluated by employing different assays, including DPPH, ABTS radical scavenging assays, FRAP, phosphomolybdenum reduction assay, superoxide anion, hydroxyl radical scavenging activities and metal chelating ability. Results: Acetone and methanol extracts recorded higher phenolic content and showed comparable antioxidant activity with standard reference. Additionally, they also inhibited the proliferation of HT-29 cells upon treatment at higher concentration (200 μg/mL) (acetone and methanol, 84% and 84%, respectively). On examination acetone extract exhibited antiproliferative activity in a concentration dependent manner whereas, methanol extract showed both dose dependent and time dependent inhibitory activity. Conclusions: The results obtained justify the traditional usage of R. imbricata from their promising antioxidant activity.

  14. Effects of luteectomy in early pregnancy on the maintenance of gestation and plasma progesterone concentrations in the viviparous temperate lizard Barisia imbricata imbricata

    Full Text Available Abstract Background Several studies have shown that the corpus luteum is the principal source of progesterone during the gravidity period in reptiles; however, its participation in the maintenance of gestation in the viviparous squamata is in dispute. The effects of ovariectomy or luteectomy vary according to the species and the time at which the procedure is performed. In this paper, we describe the effects of luteectomy during early pregnancy on the maintenance of gestation and progesterone concentrations in the temperate Mexican viviparous lizard Barisia imbricata imbricata. Methods Twenty-four lizards were subjected to three different treatments: luteectomy, sham luteectomy or non-surgical treatment, and blood samples were obtained before and after surgical treatment at different stages of gestation to determine the effects of luteectomy on the maintenance of gestation and progesterone concentrations. Results Spontaneous abortion was not observed in any of the females. However, luteectomy provoked abnormal parturition and a significant reduction in the number of young born alive. Parturition was normal in untreated females as well as those submitted to sham luteectomy. The surgical treatment also caused a significant reduction in progesterone concentrations in luteectomised females during early and middle gestation. However, no significant differences in hormone concentrations were observed among the three groups during late gestation or immediately post-parturition. Conclusions Our observations indicate that the presence of the corpus luteum is not necesary for the maintenance of gestation, but that it does participate in parturition control. Moreover, the corpus luteum of the viviparous lizard B. i. imbricata produces progesterone, at least during the first half of pregnancy, and that an extra-ovarian source of progesterone must maintain gestation in the absence of luteal tissue.

    In 1994, Braddock and Carey first reported two unrelated girls with a new multiple malformation syndrome. The primary features included Pierre Robin sequence, persistent neonatal-onset thrombocytopenia, agenesis of the corpus callosum, a distinctive facies, enamel hypoplasia, and severe developmental delay. Since that time, there have been multiple other reported patients with a similar phenotype. In addition, several reports of thrombocytopenia and developmental delay have been documented in association with deletions in the Down syndrome critical region at 21q22. The similarity of the reported cases with deletions involving 21q22 with the clinical presentation of the two patients with Braddock-Carey syndrome resulted in a reinvestigation of the genetic etiology of these two patients 20 years after the original study. This investigation provides evidence that the etiology of this and other "Fanconi-like" disorders represent a newly recognized contiguous gene deletion syndrome involving 21q22 and specifically, the RUNX1 gene. © 2016 Wiley Periodicals, Inc.

    Fire recurrently affects many of the terrestrial ecosystems causing major implications on the structure and dynamics of vegetation. In fire prone, it is particularly important to know the fire regime for which precise fire records are needed. Dendroecology offers the possibility of obtaining fire occurrence data from woody species and has been widely used in forest ecosystems for fire research. Grasslands are regions with no trees but shrubs could be used to acquire dendroecological information in order to reconstructing fire history at landscape scale. We studied the dendroecological potential of shrub F. imbricata to reconstruct fire history at landscape scale in a fire prone grassland of northwestern Patagonia. To do this, we combined spatio-temporal information of recorded fires within the study area with the age structure of F. imbricata shrublands derived by dendroecology. Sampling sites were located over 2500 ha in San Ramón ranch, 30 km east from Bariloche, Río Negro province, Argentina (latitude -41° 04'; longitude -70° 51'). Shrubland age structure correctly described how fires occurred in the past. Pulses of individuals' recruitment were associated with fire in time and space. A bi-variate analysis showed that F. imbricata recruits individuals during the two years after fire and spatial distribution of pulses coincided with the fire map. In sites without fire data, the age structure allowed the identification of two additional fires. Our results show that shrub F. imbricata can be employed with other data sources such as remote sensing and operational databases to improve knowledge on fire regime in northwestern Patagonia grasslands. In conclusion, we raise the possibility of utilizing shrubs as a dendroecological data source to study fire history in grasslands where tree cover is absent.

  17. Spermiogenesis in the imbricate alligator lizard, Barisia imbricata (Reptilia, Squamata, Anguidae).

    Although the events of spermiogenesis are commonly studied in amniotes, the amount of research available for Squamata is lacking. Many studies have described the morphological characteristics of mature spermatozoa in squamates, but few detail the ultrastructural changes that occur during spermiogenesis. This study's purpose is to gain a better understanding of the subcellular events of spermatid development within the Imbricate Alligator Lizard, Barisia imbricata. The morphological data presented here represent the first complete ultrastructural study of spermiogenesis within the family Anguidae. Samples of testes from four specimens collected on the northwest side of the Nevado de Toluca, México, were prepared using standard techniques for transmission electron microscopy. Many of the ultrastructural changes occurring during spermiogenesis within B. imbricata are similar to that of other squamates (i.e., early acrosome formation, chromatin condensation, flagella formation, annulus present, and a prominent manchette). However, there are a few unique characteristics within B. imbricata spermatids that to date have not been described during spermiogenesis in other squamates. For example, penetration of the acrosomal granule into the subacrosomal space to form the basal plate of the perforatorium during round spermatid development, the clover-shaped morphology of the developing nuclear fossa of the flagellum, and the bulbous shape to the perforatorium are all unique to the Imbricate Alligator Lizard. These anatomical character differences may be valuable nontraditional data that along with more traditional matrices (such as DNA sequences and gross morphological data) may help elucidate phylogenetic relationships, which are historically considered controversial within Squamata.

    Full Text Available Fire is a critical disturbance in the structuring and functioning of most Mediterranean ecosystems. In northwestern Patagonia, vegetation patterns are strongly influenced by fire and environmental heterogeneity. Dendroecology, together with satellite imagery and GIS, have been demonstrated to be useful tools in studies that relate to fire effects with patches, patterns and species dynamics at landscape scale. Such studies can be approached from landscape ecology, which has evolved in the last years supported by the development of remote sensing and GIS technologies. This study evaluates the spatial dynamic of F. imbricata in response to fire using remote sensing, GIS and dendrochronology techniques, at landscape scale. Two sites were evaluated and one of them was affected by fire in the year 1999. The digital processing images (using the NBR spectral index and the dendroecological analysis verified this. A fire, occurring in 1978, was also detected by the analysis of F. imbricata growth rings. The relation between F. imbricata shrubland dynamics and spatial configuration with fire, land topography and hydrography was established in the study area.

    It is generally accepted that progesterone is necessary to maintain gestation; however, the mechanisms that control the production of this steroid remain unknown. The corpus luteum has been assigned a central role in the maintenance of gestation based on its capacity to produce progesterone. A pseudopregnancy model was performed in a viviparous lizard, Barisia imbricata imbricata, to determine whether the absence of embryos would affect the pattern of progesterone production or the corpus luteum histology. Blood samples were obtained prior to ovulation and at 8, 16, and 24 weeks after ovulation (pseudopregnant and pregnant lizards), as well as one day after parturition (pregnant lizards) or 32 weeks after ovulation (pseudopregnant lizards). The corpus luteum was surgically removed one day after blood samples were obtained. Blood aliquots from nongravid females were obtained at similar timepoints. We found a significant reduction in plasma progesterone concentrations at 24 and 32 weeks post-ovulation in pseudopregnant lizards compared with those observed at similar times in intact pregnant lizards, whereas the progesterone levels in non-gestant lizards remained significantly lower than in either pseudopregnant or pregnant lizards. Moreover, we observed that the histological appearance of the corpus luteum from pseudogestational females (obtained 24 and 32 weeks post-ovulation) differed from the corpora lutea from lizards in late gestation and intact parturient lizards. These observations suggest that the conceptus participates in the regulation of progesterone production in late gestation and also in luteolysis control.

  4. A modification of the method of Carey and Sparks (1986) to estimate eruption column height from maximum clast dispersal

    The method of Carey and Sparks (1986) has been widely applied to estimate the hight of eruptive columns from the dispersal of the maximum clast size. These authors presented curves of maximum downwind range versus crosswind range for different clast diameters and wind speeds obtained from the numerical solution of a column model developed by Sparks(1986). An improved model of eruptive column was later developed by Woods (1988). In this work we present the results of the simulation of clast dispersal following the procedure of Carey and Sparks (1986) and the eruption column of Woods (1988). The numerical calculations were carried out with a code that computes the height of the column and the vertical velocity, the density and the radius along the column. The code determines then the support envelopes for a given clast size and their fall, after leaving the column, are computed from the equations of motion with viscous friction. For the same downwind and crosswind ranges, this method yields column heights about 10% smaller than the method of Carey and Sparks and about 20% higher wind velocities. The height of the crater above sea level plays also a small role in the results. We present comparisons for the 1982 eruption columns from El Chichon volcano.

    Evidence from both field observations and experimental work indicates that predation by larvae of a midge, Pentaneura n. sp. (Chironomidae), causes the low densities of mosquito larvae (Culicidae) found in the water filled bracts of Heliconia imbricata (Musaceae), microhabitats typically colonized by mosquitoes. This predation affects 2 species of mosquitoes, Wyeomyia pseudopecten, a resident species, and Trichoprosopon digitatum, a non-resident species. Predation keeps resident mosquito densities low while completely excluding the nonresident mosquito from the habitat. Both these effects of predation depend on the presence of an abundant alternative prey, an undescribed species of harpacticoid copepod found in the bracts. These copepod prey sustain chironomids when resident mosquito densities are low, permiting predator densities to remain high enough to exclude the non-resident mosquito. I discuss the evolutionary and ecological implications of predation structuring communities.

    Despite increased worldwide popularity of keeping reptiles as pets, we know little about hematologic and biochemical parameters of most reptile species, or how these measures may be influenced by intrinsic and extrinsic factors. Blood samples from 43 wild-caught pythons (Morelia spilota imbricata) were collected at various stages of a 3-yr ecological study in Western Australia. Reference intervals are reported for 35 individuals sampled at the commencement of the study. As pythons were radiotracked for varying lengths of time (radiotransmitters were surgically implanted), repeated sampling was undertaken from some individuals. However, because of our ad hoc sampling design we cannot be definitive about temporal factors that were most important or that exclusively influenced blood parameters. There was no significant effect of sex or the presence of a hemogregarine parasite on blood parameters. Erythrocyte measures were highest for pythons captured in the jarrah forest and at the stage of radiotransmitter implantation, which was also linked with shorter time in captivity. Basophil count, the only leukocyte influenced by the factors tested, was highest when the python was anesthetized, as was globulin concentration. Albumin and the albumin:globulin ratio were more concentrated in summer (as was phosphorous) and at the initial stage of radiotransmitter placement (as was calcium). No intrinsic or extrinsic factors influenced creatinine kinase, aspartate aminotransferase, uric acid, or total protein. This study demonstrates that factors including season, location, surgical radiotransmitter placement, and anesthetic state can influence blood parameters of M. s. imbricata. For accurate diagnosis, veterinarians should be aware that the current reference intervals used to identify the health status of individuals for this species are outdated and the interpretation and an understanding of the influence of intrinsic and extrinsic factors are limited.

    The Carey-Finema-Ziter syndrome (CFZS, MIM 254940) is an apparently autosomal recessively inherited disorder consisting of the combination of non-progressive congenital myopathy with Moebius and Pierre Robin sequence, facial anomalies and growth delay. Mental development has been described as normal or delayed. Temporomandibular joint (TMJ) ankylosis is the immobility of the joint caused by ankylotic fusion of the mandible to the cranial base or zygoma. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and oral hygiene. Most often is a true ankylosis of the TMJ but other pathological mechanisms are described (i.e., the fusion of the coronoid process to temporal bone or with the zygoma, or a variety of soft tissues disorders like Fibrodysplasia Ossificans Progressiva). Here we report a 2-year-old girl fitting with a clinical diagnosis of CFZS associated with a limited mouth opening in which temporomandibular joint ankylosis was suspected. Because it has been postulated that many clinical features in CFZS may only be secondary effects of brainstem anomalies and muscle weakness during development, the limited opening of the mouth observed in our patient could represent a rare clinical feature of CFZS itself. © 2016 Wiley Periodicals, Inc.

    Full Text Available Wave energy and storm surges threaten coastal ecology and nearshore infrastructures. Although coastal structures are conventionally constructed to dampen the wave energy, they introduce tremendous damage to the ecology of the coast. To minimize environmental impact, ecofriendly coastal protection schemes should be introduced. In this paper, we discuss an example of an innovative mangrove rehabilitation attempt to restore the endangered mangroves on Carey Island, Malaysia. A submerged detached breakwater system was constructed to dampen the energy of wave and trap the sediments behind the structure. Further, a large number of mangrove seedlings were planted using different techniques. Further, we assess the possibility of success for a future mangrove rehabilitation project at the site in the context of sedimentology, bathymetry, and hydrogeochemistry. The assessment showed an increase in the amount of silt and clay, and the seabed was noticeably elevated. The nutrient concentration, the pH value, and the salinity index demonstrate that the site is conducive in establishing mangrove seedlings. As a result, we conclude that the site is now ready for attempts to rehabilitate the lost mangrove forest.

    The investigation of mammalian malformations began to approach human needs in the 19th century with, for example, Meckel's dissection of sibs with the "Meckel" syndrome, his intimation of Heredität as cause of the condition, his conclusion as to the common causal origin of this specific combination of congenital anomalies, the clear enunciation of the concept of primary malformations, the recognition that many human malformations are normal developmental states in other animals, and that some were normal anatomical states in remote ancestors and now still normal in collateral descendants (atavisms, Darwin's "reversions"; for example, four wings in dipterans, normal in dragonflies and their common ancestor). Later in the century, Wilhelm His Sr. had proposed a schematic map of "organ-forming districts" for prospective chick development, a concept that did not sit well with early workers in developmental biology (e.g., Boveri) until methods became available for a direct experimental "attack" on the embryo. This approach was pioneered by Spemann and Mangold through interspecies transplantation of embryonic rudiments with the spectacular result that set the research stage in developmental biology for the next many years. But it was not until mid-century that the late, great geneticist, Curt Stern, made the His model of chick development more intellectually and experimentally approachable with his meticulous analysis of cuticular appendages of Drosophila, one bristle and one bristle group (field) at a time, in mosaics or gynandromorphs, leading to the ingenious concept of prepatterns. As a basic scientist, Stern did not broaden prepatterns into medicine or to human malformations where it has now found a most gratifying application. This contribution to the Carey Festschrift is to summarize, briefly, field and prepattern theory. © 2016 Wiley Periodicals, Inc.

    Full Text Available The present study focused on the use of a composite electrode in the anodic compartment to increase energy output and reduce the cost of Microbial Fuel Cell (MFC. In order to transfer electrons by conduction by electrogenic microorganisms to the electrode this have to be in direct contact with the electrode, being this a limitation to MFC due to limited surface area available in electrode. A two-chamber MFC was used, with graphite electrodes, anodic electrode was inserted in a small piece of coyonoztle (Opuntia imbricata. MFC was operated in fedbatch mode during a period of 60 days, using glucose as carbon source glucose (3 g/L, three external loads were used (5.5 KΩ, 1 KΩ and 560 Ω.

    Full Text Available Reported researches dealing with either composition or bioactivity of Salsola imbricata are limited. This study was conducted aiming to investigate the phenolic composition of the plant and evaluate its efficacy as male contraceptive. Polyphenols, namely, phenolic acids and flavonoids, were qualitatively and quantitatively analysed by RP-HPLC in the hydrolysed methanol extract using two different wavelengths, 280 and 330 nm. The efficiency of different solvents in extracting the plant phenolics was assessed via spectrophotometric determination of the total phenolic and flavonoid contents. Acute toxicity study was carried out on the ethanolic extract to ascertain its safety prior to biological evaluation. The contraceptive effect was assessed, in male rats, by oral administration of the extract at two doses (250 and 500 mg/kg b. wt., over a period of 65 days. HPLC analyses allowed the identification and quantification of a total of 13 and 8 components in the hydrolysed-methanol extract; the overall phenolic composition was dominated by quercitrin (12.692% followed by coumaric acid (4.251%. Prolonged oral administration of the ethanolic extract caused slight reduction in the testis weight only. A significant decrease in the sperm count was observed (P<0.01 in the two treated groups while significant decrease in the epididymal sperm motility was only observed in the high dose group. Morphological abnormalities were observed in sperms of treated animals. No distinct change in serum FSH, LH, and testosterone concentration was recorded. The histopathological findings supported to a high extent these results. The male contraceptive activity of Salsola imbricata could be ascribed to its phenolic components, especially quercitrin.

    During a long time,Chinese scholars pay less attention to Peter Carey. Until 1 979,Huang Yuanshen and other scholars came to the university of Sydney,who had officially opened the prelude of Chinese study on Peter Carey. In the 1 990s, with the development of the reform and opening up of our country,the research on Peter Carey gradually entered into a stage of development. Since the 21st century,the study on Peter Carey has steady development. In general,the study on Peter Carey in China starts late,but has steady development.%在很长时间内,我国学者对彼得·凯里的关注不多。直到1979年,黄源深等人来到悉尼大学,正式拉开彼得·凯里研究的序幕。20世纪90年代,在中国改革开放的大背景下,我国对彼得·凯里的研究走上正轨。进入21世纪以来,我国对彼得·凯里的研究稳步发展。总体而言,我国对彼得·凯里的研究起步较晚,但发展稳步迅速。

    The sexual development of saurians follows a similar pattern to that described for other amniotes. Changes in the timing or sequence of development events are known as heterochrony. We describe the pattern of sexual development in the viviparous Mexican lizard Barisia imbricata and report heterochrony in the regression of hemipenes in this lizard. We collected gestating females; some lizards were subjected to partial hysterectomy and the embryos were processed using routine histological technique to assess gonadal development; the remaining embryos were used to assess the development of hemipenes. Other pregnant females were kept in captivity in individual terraria until the time of delivery. All neonates were sexed by eversion of hemipenes and some of their body characteristics were recorded. Several neonates were sacrificed and processed to establish gonadal histology and the young of the remaining litters were maintained in captivity to observe the fate of the hemipenes in both sexes. Gonadal development began at embryonic stage 33 and the hemipenes were visible at the same stage. In the neonates, the ovary contained oogonias and ovarian follicles, whereas the testicles showed testicular cords. All neonates had hemipenes and sex could only be established through direct observation of the reproductive ducts and gonadal histology. The hemipenes regression in the females begins after approximately 7 months of postnatal development and concludes at about 15 months of age. We think that the delayed regression of the hemipenes reflects evolutionary differences among reptiles and may be an indication of a stage in the evolutionary process of this species.

  7. Peter Carey's Laptop

    2014-03-01

    Full Text Available In 2001, the State Library of Victoria in Melbourne built on its holdings of Australian literary manuscripts by acquiring all the papers, drafts and other items associated with Peter Carey’s Booker Prize-winning novel, True History of the Kelly Gang. The centrepiece of this acquisition, and the focus of this article, is Carey’s Apple Mac Classic laptop computer. The argument that is developed in this article is that Carey’s laptop is a technological artefact that operates, especially at the time of its acquisition, as an important talisman in three interrelated senses. First, it was viewed by library staff as a key means of gaining access to the ‘true history’ of Carey’s own creative drive or creative unconscious. Second, its public display alongside other textual objects (mostly books served to reinforce a reconstructed corporate image that endeavoured to reposition the library as a vital contemporary cultural site and key player in Melbourne’s institutional gallery scene. Third, it was a crucial symbolic acquisition insofar as it spoke to certain desires within library management at that time, and which responded to similar moves at major libraries elsewhere around the world, to embrace collection digitisation as the path forward.

    By using the integral identities and the interpolation postprocessing technique, the higher accuracy approximation of the anisotropic nonconforming Carey element for solving the Sobolev type equations is investigated. Firstly, the interpolation operator is constructed, the superclose, global superconvergence and posteriori error estimate are obtained with the help of the distinct property of Carey elements, i.e., the linear interpolation of the solution for Carey elements is equal to the solution for linear triangular element. Secondly, by virtue of the extrapolation method, the accuracy of the related approximate solution with fourth order is derived through the asymptotic error expansion.%利用积分恒等式和插值后处理技术,本文在各向异性网格上对Sobolev型方程的Carey非协调有限元解进行高精度算法分析.首先,根据Carey元的特性,即其有限元解的线性插值和线性元解相同,我们构造插值后处理算子,得到了有限元解的超逼近性质和整体超收敛及后验误差估计.接着,根据误差渐近展开式,运用外推方法,进一步得到了具有四阶精度的近似解.

    In order to study the molecular structure of the anthocyanins which are induced by Cd in Azolla imbricata, anthocyanins were induced with 0.1mg·L-1 Cd, extracted with 0.1% HCI in methanol, purified by an Amberlite XAD-7 column and separated by Sephedex LH-20 column. The main compound was preliminarily identified as luteolinidin- 5-glucoside by its ultraviolet/visible absorbance spectrum and high performance liquid ( HPLC )chromatography. In vitro antioxidant properties of anthocyanins before and after purification were also evaluated by different analytical methods. The results showed that the total antioxidant capacity, reducing power, scavenging activity of superoxide anion radical (O2 - )and hydroxyl radical ( · OH )increased significantly with increasing concentrations of anthocyanin extracts, and the antioxidant activity of anthocyanins after purification was higher than the values of anthocyanins before purification. When the concentration of anthocyanins reached 0. 5 mg · mL-1, the values of anthocyanins after purification were increased by 3.16,1.36,2.71 and 1.86 times respectively, compared to anthocyanins before purification, indicating that luteolinidin-5-glucoside was the most important substance responsible for the antioxidant properties of A. imbricata. In addition, the antioxidant mechanism of anthocyanins is also discussed in this paper. In conclusion, the results obtained in this work indicated that the increase in the content of anthocyanins may be involved in internal detoxification mechanisms of A. imbricata against Cd toxicity.%为了研究镉诱导的满江红花色素苷的分子结构,分别用0.1 mg·L-1Cd、0.1%盐酸-甲醇溶液、XAD-7大孔树脂和葡聚糖凝胶SephadexLH-20柱对其进行诱导、提取、纯化和分离.经紫外可见光谱特性和HPLC图谱分析.初步确定此物质为木犀草定-5-葡萄糖苷.采用不同的体外实验方法评价了满江红花色素苷纯化前后的抗氧化活性.结果表明,花

    Adult hawksbill turtles (Eretmochelys imbricata) are typically described as open-coast, coral reef and hard substrate dwellers. Here, we report new satellite tracking data on female hawksbills from several countries in the eastern Pacific that revealed previously undocumented behaviour for adults of the species. In contrast to patterns of habitat use exhibited by their Caribbean and Indo-Pacific counterparts, eastern Pacific hawksbills generally occupied inshore estuaries, wherein they had strong associations with mangrove saltwater forests. The use of inshore habitats and affinities with mangrove saltwater forests presents a previously unknown life-history paradigm for adult hawksbill turtles and suggests a potentially unique evolutionary trajectory for the species. Our findings highlight the variability in life-history strategies that marine turtles and other wide-ranging marine wildlife may exhibit among ocean regions, and the importance of understanding such disparities from an ecological and management perspective.

    The objective of this research is to present the results of the marine chelonians stranding monitoring developed during and after the seismic survey in the north area of Rio de Janeiro and south of Espirito Santo. The monitoring lasted six months, reaching 200 km of beaches, from the Rio de Janeiro North up to the Espirito Santo South coasts. It was conducted by 34 monitors, who covered predefined beach sections daily, registering the stranded animals. At the end of the project, 159 chelonians stranded were registered. The species Chelonia mydas was prevailing in number and distribution. This species make use of this beach area to food. Lepidochelys olivacea was the second species in geographic distribution and number of registers. The other species identified were Caretta caretta and Eretmochelys imbricata. There was only one reproductive register, of Caretta caretta species. (author)

    Documenting the extent of fishery gear interactions is critical to wildlife conservation efforts, especially for reducing entanglements and ingestion. This study summarizes fishery gear interactions involving common bottlenose dolphins (Tursiops truncatus truncatus), Florida manatees (Trichechus manatus latirostris) and sea turtles: loggerhead (Caretta caretta), green turtle (Chelonia mydas), leatherback (Dermochelys coriacea), hawksbill (Eretmochelys imbricata), Kemp's ridley (Lepidochelys kempii), and olive ridley (Lepidochelys olivacea) stranding in Florida waters during 1997-2009. Fishery gear interactions for all species combined were 75.3% hook and line, 18.2% trap pot gear, 4.8% fishing nets, and 1.7% in multiple gears. Total reported fishery gear cases increased over time for dolphins (pstrandings relative to total strandings for loggerhead sea turtles increased (p<0.05). Additionally, life stage and sex patterns were examined, fishery gear interaction hotspots were identified and generalized linear regression modeling was conducted.

    Full Text Available An overview is presented for a poorly documented relationship between reef vertebrates in Southwest Atlantic: remoras (Echeneidae associated with marine turtles. Two remora species (Echeneis naucrates and Remora remora and four turtle species (Caretta caretta, Chelonia mydas, Eretmochelys imbricata, and Dermochelys coriacea are here recorded in symbiotic associations in the SW Atlantic. Echeneis naucrates was recorded both on the coast and on oceanic islands, whereas R. remora was recorded only at oceanic islands and in the open sea. The remora-turtle association is usually regarded as an instance of phoresis (hitchhiking, albeit feeding by the fish is also involved in this symbiosis type. This association seems to be rare in SW Atlantic.

    Five species of sea turtles occur along the United States coastlines and are listed as threatened or endangered. The loggerhead sea turtle (Caretta caretta) is listed as threatened, while the Kemp`s ridley (Lepidochelys kenipi), the hawksbill (Eretmochelys imbricata), and the leatherback (Dermochelys coriacea) are all less abundant and listed as endangered. Florida breeding populations of the green sea turtle (Chelonia mydas) are listed as endangered, but green turtles in other US waters are considered threatened. The National Marine Fisheries Service (NMFS) has determined, based on the best available information, that because of their life cycle and behavioral patterns only the loggerhead, the green, and the Kemp`s ridley are put at risk by hopper dredging activities (Studt 1987).

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

    Full Text Available El monitoreo de las anidaciones es muy útil como herramienta para la conservación pero el esfuerzo de trabajo en diferentes áreas puede variar grandemente. En Cuba, se aplican cuatro enfoques diferentes: monitoreo sistemático nocturno y diurno (MSN, y monitoreo esporádico con o sin comprobación de nidos (MECC. La cantidad y exactitud de los datos tomados y la calidad de la información derivada de ellos difieren. Por esta razón, en el presente trabajo se evalúa la efectividad de cada enfoque para determinar el éxito reproductivo de tortugas marinas en Cuba. El MSN sólo se realiza en las playas de anidación de la Península de Guanahacabibes, mientras que el MECC es el más extendido en el país. La porción de la temporada de anidación de cada una de las tres especies que anidan en Cuba (Chelonia mydas, Caretta caretta y Eretmochelys imbricata que se cubre con personal de monitoreo es baja para la mayoría de las playas, y sobre todo en el caso de E. imbricata. Se detectaron diferencias entre el monitoreo sistemático y esporádico, por tanto, la capacidad de detectar rastros falsos y verdaderos depende esencialmente de la frecuencia de monitoreo. Esto afecta la capacidad para evaluar el éxito de la anidación por playas. A pesar del incremento en los esfuerzos realizados en Cuba para el seguimiento de las principales colonias de anidación, se deben identificar nuevas estrategias para garantizar la correcta toma de información, y una mayor eficiencia del programa de monitoreo para obtener la mayor información posible de cada una de las especies con un adecuado balance de costo-beneficio.

    2011-05-01

    Full Text Available Strandings and incidental catches of four sea turtles species (Chelonia mydas, Lepidochelys olivacea, Dermochelys coriacea and Eretmochelys imbricata were registered in Tumbes Region since August 2007 to August 2009. These registers (52.6% of strandings and 47.4% of incidental catches occurred during all year; most frequently in Punta Picos (50.5%, Canoas (20.0% and Baja de Punta Mero (14.7%. The most registered species were C. mydas (64.2% and L. olivacea (30.5%; their sizes did not present significant differences between areas and climatic seasons. The higher percentage of C. mydas, L. olivacea and D. coriacea were considered sub-adults, including the only specimen of E. imbricata. The incidental catches were made with gillnets of different mesh sizes, but 8 inches mesh was most frequently. A high proportions of specimens were died with signs of drowning (22.2% this was due to the prolonged time of soak time of gillnet (approximately 12 hours. No significant differences in CPUE were found between climatic seasons and no seasonal pattern was evident. Lesions in 14% of stranded specimens were caused possibly by human attacks or by collisions with fishing boats. 77.8% of incidental catch specimens were sacrificed for the commercialization of his meat, and sometimes of his shell, this shows the lack of awareness of conservation. These observations indicate that the coast of Tumbes is an important foraging area and development of sub-adult specimens of sea turtles; so it is recomend to develop monitoring, awareness and critical areas protection programs to foment the conservation of these organisms in the Eastern Pacific.

    We set out to develop an oviposition induction technique for captive female hawksbill turtles Eretmochelys imbricata. The infertile eggs of nine females were induced to develop by the administration of follicle-stimulating hormone, after which we investigated the effects of administering oxytocin on oviposition. Seven of the turtles were held in a stationary horizontal position on a retention stand, and then oxytocin was administrated (0.6-0.8 units/kg of body weight; 5 mL). The seven turtles were retained for a mandatory 2 h period after oxytocin administration, and were then returned to the holding tanks. As the control, normal saline (5 mL) was administered to the other two turtles, followed by the administration of oxytocin after 24 h. The eggs in oviducts of all nine turtles were observed by ultrasonography at 24 h after oxytocin administration. The control experiment validated that stationary retention and normal saline administration had no effect on egg oviposition. Eight of the turtles began ovipositing eggs at 17-43 min after oxytocin administration, while one began ovipositing in the holding tank immediately after retention. All turtles finished ovipositing eggs within 24 h of oxytocin administration. This report is the first to demonstrate successful induced oviposition in sea turtles. We suggest that the muscles in the oviducts of hawksbill turtles may respond to relatively lower doses of oxytocin (inducing contractions) compared to land and freshwater turtles (4-40 units/kg) based on existing studies.

    Hawksbill turtle (Eretmochelys imbricata) populations have experienced global decline because of a history of intense commercial exploitation for shell and stuffed taxidermied whole animals, and harvest for eggs and meat. Improved understanding of genetic diversity and phylogeography is needed to aid conservation. In this study, we analyzed the most geographically comprehensive sample of hawksbill turtles from the Indo-Pacific Ocean, sequencing 766 bp of the mitochondrial control region from 13 locations (plus Aldabra, n = 4) spanning over 13500 km. Our analysis of 492 samples revealed 52 haplotypes distributed in 5 divergent clades. Diversification times differed between the Indo-Pacific and Atlantic lineages and appear to be related to the sea-level changes that occurred during the Last Glacial Maximum. We found signals of demographic expansion only for turtles from the Persian Gulf region, which can be tied to a more recent colonization event. Our analyses revealed evidence of transoceanic migration, including connections between feeding grounds from the Atlantic Ocean and Indo-Pacific rookeries. Hawksbill turtles appear to have a complex pattern of phylogeography, showing a weak isolation by distance and evidence of multiple colonization events. Our novel dataset will allow mixed-stock analyses of hawksbill turtle feeding grounds in the Indo-Pacific by providing baseline data needed for conservation efforts in the region. Eight management units are proposed in our study for the Indo-Pacific region that can be incorporated in conservation plans of this critically endangered species.

  1. Diversity, habitat distribution, and indigenous hunting of marine turtles in the Calamian Islands, Palawan, Republic of the Philippines

    2016-03-01

    Full Text Available All of the world’s seven species of marine turtle are threatened by a multitude of anthropogenic pressures across all stages of their life history. The Calamian Islands, Palawan, Philippines provide important foraging and nesting grounds for four species: green turtles (Chelonia mydas, hawksbill turtles (Eretmochelys imbricata, loggerheads (Caretta caretta, and leatherbacks (Dermochelys coriacea. This work aimed to assess the relative importance of turtle nesting beaches and local threats using a combination of social science and ecological research approaches. Endangered green turtles and critically endangered hawksbills were found to nest in the Calamianes. The most important nesting sites were located on the islands off the west of Busuanga and Culion, particularly Pamalican and Galoc and along the north coast of Coron, particularly Linamodio Island. Opportunistic hunting and egg collection, conducted legally by indigenous communities, is the most significant threat to sea turtles in the area. Sites particularly vulnerable to hunting were found to be Galoc Island, Pamalican Island, and Panlaitan Island. Raising awareness, community engagement, and understanding of socio-cultural drivers of sea turtle exploitation, particularly among indigenous communities, are essential to gain support for any effective conservation program. Additionally, more effective enforcement of laws related to the trade in sea turtle products is required to close the commercial and export markets.

    Little is known about the effects of jaguars on the population of marine turtles nesting in Tortuguero National Park, Costa Rica. This study assessed jaguar predation impact on three species of marine turtles (Chelonia mydas, Dermochelys coriacea and Eretmochelys imbricata) that nest in Tortuguero beach. Jaguar predation data was obtained by using two methodologies, literature review (historical records prior the year 2005) and weekly surveys along the 29 km stretch of beach during the period 2005-2013. Our results indicated that jaguar predation has increased from one marine turtle in 1981 to 198 in 2013. Jaguars consumed annually an average of 120 (SD = 45) and 2 (SD = 3) green turtles and leatherbacks in Tortuguero beach, respectively. Based on our results we concluded that jaguars do not represent a threat to the population of green turtles that nest in Tortuguero beach, and it is not the main cause for population decline for leatherbacks and hawksbills. Future research should focus on continuing to monitor this predator-prey relationship as well as the factors that influence it so the proper management decisions can be taken.

    Full Text Available ABSTRACT Currently, plastics are recognized as a major pollutant of the marine environment, representing a serious threat to ocean wildlife. Here, we examined the occurrence and effects of plastic ingestion by sea turtles found stranded along the coast of Paraíba State, Brazil from August 2009 to July 2010. Ninety-eight digestive tracts were examined, with plastic found in 20 (20.4%. Sixty five percent (n = 13 of turtles with plastic in the digestive tract were green turtles (Chelonia mydas, 25% (n = 5 were hawksbills (Eretmochelys imbricata, and 10% (n = 2 were olive ridley (Lepidochelys olivacea. More plastic was found in the intestine (85% than in other parts of the gastrointestinal tract. We observed complete blockage of the gastrointestinal tract due to the presence of plastic in 13 of the 20 turtles that had ingested plastic. No correlation was found between the curved carapace length (CCL and the number or mass of the plastic ingested items. Significant differences were found between the intake of hard and soft plastic and the ingestion of white/transparent and colored plastic, with soft and white/transparent plastics being more commonly ingested. This study reveals the serious problem of plastic pollution to sea turtles at the area.

  4. The role of turtles as coral reef macroherbivores

    Goatley, Christopher H. R.

    2012-06-29

    Herbivory is widely accepted as a vital function on coral reefs. To date, the majority of studies examining herbivory in coral reef environments have focused on the roles of fishes and/or urchins, with relatively few studies considering the potential role of macroherbivores in reef processes. Here, we introduce evidence that highlights the potential role of marine turtles as herbivores on coral reefs. While conducting experimental habitat manipulations to assess the roles of herbivorous reef fishes we observed green turtles (Chelonia mydas) and hawksbill turtles (Eretmochelys imbricata) showing responses that were remarkably similar to those of herbivorous fishes. Reducing the sediment load of the epilithic algal matrix on a coral reef resulted in a forty-fold increase in grazing by green turtles. Hawksbill turtles were also observed to browse transplanted thalli of the macroalga Sargassum swartzii in a coral reef environment. These responses not only show strong parallels to herbivorous reef fishes, but also highlight that marine turtles actively, and intentionally, remove algae from coral reefs. When considering the size and potential historical abundance of marine turtles we suggest that these potentially valuable herbivores may have been lost from many coral reefs before their true importance was understood. © 2012 Goatley et al.

    The rates of oxidative metabolism of two tetrachlorobiphenyl congeners were determined in hepatic microsomes from four species of sea turtles, green (Chelonia mydas), olive ridley (Lepidochelys olivacea), loggerhead (Caretta caretta), and hawksbill (Eretmochelys imbricata). Hydroxylation of 3,3',4,4'-tetrachlorobiphenyl (PCB 77), an ortho-meta unsubstituted rodent cytochrome P450 (P450) 1A substrate PCB, was not observed in sea turtle microsomes. Sea turtle microsomes hydroxylated 2,2',5,5'-tetrachlorobiphenyl (PCB 52), a meta-para unsubstituted rodent P450 family 2 substrate PCB, at rates ranging from less than 0.5 to 53 pmol/min/mg protein. The P450 inhibitor ketoconazole inhibited hydroxylation of PCB 52, supporting the role of P450 catalysis. Sea turtle PCB 52 hydroxlyation rates strongly correlated with immunodetected P450 family 2-like and less so with P450 family 3-like hepatic proteins. Testosterone 6β-, 16α-, 16β-hydroxylase activities were also significantly correlated with the expression of these enzymes, indicating that P450 family 2 or P450 family 3 proteins are responsible for PCB hydroxylation in sea turtles. This study indicated species-specific PCB biotransformation in sea turtles and preferential elimination of meta-para unsubstituted PCB congeners over ortho-meta unsubstituted PCB congeners consistent with PCB accumulation patterns observed in tissues of sea turtles.

    Sand temperatures at nest depths and implications for hatchling sex ratios of hawksbill turtles (Eretmochelys imbricata) and green turtles (Chelonia mydas) nesting in the Chagos Archipelago, Indian Ocean are reported and compared to similar measurements at rookeries in the Atlantic and Caribbean. During 2012–2014, temperature loggers were buried at depths and in beach zones representative of turtle nesting sites. Data collected for 12,546 days revealed seasonal and spatial patterns of sand temperature. Depth effects were minimal, perhaps modulated by shade from vegetation. Coolest and warmest temperatures were recorded in the sites heavily shaded in vegetation during the austral winter and in sites partially shaded in vegetation during summer respectively. Overall, sand temperatures were relatively cool during the nesting seasons of both species which would likely produce fairly balanced hatchling sex ratios of 53% and 63% male hatchlings, respectively, for hawksbill and green turtles. This result contrasts with the predominantly high female skew reported for offspring at most rookeries around the globe and highlights how local beach characteristics can drive incubation temperatures. Our evidence suggests that sites characterized by heavy shade associated with intact natural vegetation are likely to provide conditions suitable for male hatchling production in a warming world.

    Some of the most basic questions of sea turtle life history are also the most elusive. Many uncertainties surround lifespan, growth rates, maturity and spatial structure, yet these are critical factors in assessing population status. Here we examine the keratinized hard tissues of the hawksbill (Eretmochelys imbricata) carapace and use bomb radiocarbon dating to estimate growth and maturity. Scutes have an established dietary record, yet the large keratin deposits of hawksbills evoke a reliable chronology. We sectioned, polished and imaged posterior marginal scutes from 36 individual hawksbills representing all life stages, several Pacific populations and spanning eight decades. We counted the apparent growth lines, microsampled along growth contours and calibrated Δ(14)C values to reference coral series. We fit von Bertalanffy growth function (VBGF) models to the results, producing a range of age estimates for each turtle. We find Hawaii hawksbills deposit eight growth lines annually (range 5-14), with model ensembles producing a somatic growth parameter (k) of 0.13 (range 0.1-0.2) and first breeding at 29 years (range 23-36). Recent bomb radiocarbon values also suggest declining trophic status. Together, our results may reflect long-term changes in the benthic community structure of Hawaii reefs, and possibly shed light on the critical population status for Hawaii hawksbills.

    The aim of this study was to evaluate the antifungal susceptibility of Candida spp. recovered from tortoises (Chelonoidis spp.) and sea turtles (Chelonia mydas, Caretta caretta, Lepidochelys olivacea, Eretmochelys imbricata). For this purpose, material from the oral cavity and cloaca of 77 animals (60 tortoises and 17 sea turtles) was collected. The collected specimens were seeded on 2% Sabouraud dextrose agar with chloramphenicol, and the identification was carried out by morphological and biochemical methods. Sixty-six isolates were recovered from tortoises, out of which 27 were C. tropicalis, 27 C. famata, 7 C. albicans, 4 C. guilliermondii and 1 C. intermedia, whereas 12 strains were obtained from sea turtles, which were identified as Candida parapsilosis (n = 4), Candida guilliermondii (n = 4), Candida tropicalis (n = 2), Candida albicans (n = 1) and Candida intermedia (n = 1). The minimum inhibitory concentrations for amphotericin B, itraconazole and fluconazole ranged from 0.03125 to 0.5, 0.03125 to >16 and 0.125 to >64, respectively. Overall, 19 azole-resistant strains (14 C. tropicalis and 5 C. albicans) were found. Thus, this study shows that Testudines carry azole-resistant Candida spp.

    To determine habitat-use patterns of sub-adult hawksbills Eretmochelys imbricata, we conducted satellite- and acoustic-tracking of 3 turtles captured in August 2008 within Dry Tortugas National Park (DRTO), south Florida, USA, in the Gulf of Mexico; turtles ranged in size from 51.9 to 69.8 cm straight carapace length. After 263, 699, and 655 d of residence in the park, turtles migrated out of the DRTO. Within the park, core-use areas (i.e. 50% kernel density estimates) were 9.2 to 21.5 km2; all 3 turtle core-use areas overlapped in an area 6.1 km2 within a zone of the park with multiple human uses (e.g. fishing, anchoring). Two turtles migrated to Cuba and ceased transmitting after 320 and 687 tracking days; the third turtle migrated toward Key West, Florida, and ceased transmitting after 884 tracking days. The present study highlights previously unknown regional connections for hawksbills, possible turtle-harvest incidents, and fine-scale habitat use of sub-adult hawksbills within a United States National Park.

    Full Text Available This study aimed to register the ecological knowledge of fishermen from the municipality of São João de Pirabas, Pará, Brazil, regarding the occurrence of sea turtles on the Pará state coast, as well as measure their incidental capture when fishing; to do this, 50 semi-structured interviews were conducted with local fishermen. Fishing was practiced mostly by adult men, who used 7 fishing arts (gillnetting, hook and line, longline, fish corrals, net of tide canals, casting net, and basket trap, mainly aimed at catching king mackerel (Scomberomorus cavalla, serra Spanish mackerel (S. brasiliensis, king weakfish (Macrodon ancylodon, weakfish (Cynoscion spp., hake (Cynoscion spp., catfish (Bagre bagre, and mullet (Mugil spp.. Fishermen observed in the region 5 turtle species, with a more frequent occurrence of Chelonia mydas (100%, Dermochelys coriacea (66%, and Eretmochelys imbricata (46%; the less frequent species are Caretta caretta (16% and Lepidochelys olivacea (8%. The spawning areas of the 3 most common species demonstrate the significance of the Pará state coast for their conservation. Incidental capture was reported by 76% of fishermen, mainly occurring in net, longlines, and fish corrals. Usually, captured animals were released, although there is consumption of sea turtle meat and eggs by fishermen.

When compared with standard values for sea turtles, the general morphological features assigned the specimen to Caretta caretta, while the shape and coloration of the head and the beak profile fell within the Eretmochelys imbricata range; the front flippers were instead like those of a Chelonia mydas. Moreover, prefrontal scale number was outside the putative parental species’ ranges. The mitochondrial D-loop sequence was from C. caretta, and matched haplotype CC-A2.1, the most common in the Mediterranean. Sequence profiles at three nuclear loci withspecies-specific substitutions (Cmos, BDNF and R35 revealed only C. caretta variants, thus excluding that the individual wasan F1 hybrid. This study highlights the importance of integrating different methodological approaches to understand reproductive animal biology and to set the boundaries for specific morphological traits. In particular, we propose the genetic analysis of a new combination of mitochondrial and nuclear markers as a standard procedure which can be adopted in the identification of sea turtlehybrids.

    Hawksbill sea turtles (Eretmochelys imbricata) are circumtropically distributed and listed as Critically Endangered by the IUCN (Meylan & Donnelly 1999; NMFS & USFWS 1993). To aid in population recovery and protection, the Hawksbill Recovery Plan identified the need to determine demographic information for hawksbills, such as distribution, abundance, seasonal movements, foraging areas (sections 121 and 2211), growth rates, and survivorship (section 2213, NMFS & USFWS 1993). Mark-recapture analyses are helpful in estimating demographic parameters and have been used for hawksbills throughout the Caribbean (e.g., Richardson et al. 1999; Velez-Zuazo et al. 2008); integral to these studies are recaptures at the nesting site as well as remigration interval estimates (Hays 2000). Estimates of remigration intervals (the duration between nesting seasons) are critical to marine turtle population estimates and measures of nesting success (Hays 2000; Richardson et al. 1999). Although hawksbills in the Caribbean generally show natal philopatry and nesting-site fidelity (Bass et al. 1996; Bowen et al. 2007), exceptions to this have been observed for hawksbills and other marine turtles (Bowen & Karl 2007; Diamond 1976; Esteban et al. 2015; Hart et al. 2013). This flexibility in choosing a nesting beach could therefore affect the apparent remigration interval and subsequently, region-wide population counts.

    Full Text Available The status of marine turtles in Montserrat (Eastern Caribbean is reviewed following five years of monitoring (1999-2003. The mean number of nests recorded during the annual nesting season (June-October was 53 (± 24.9 SD; range: 13-43. In accordance with earlier reports, the nesting of hawksbill (Eretmochelys imbricata and green (Chelonia mydas turtles was confirmed on several beaches around the island. Only non-nesting emergences were documented for loggerhead turtles (Caretta caretta and there was no evidence of nesting by leatherback turtles (Dermochelys coriacea; however, it is possible that additional survey effort would reveal low density nesting by these species. Officially reported turtle capture data for 1993-2003 suggest that a mean of 0.9 turtle per year (±1.2 SD; range: 0-4 were landed island-wide, with all harvest having occurred during the annual open season (1 October to 31 May. Informed observers believe that the harvest is significantly under-reported and that fishermen avoid declaring their catch by butchering turtles at sea (both during and outside the open season. Of concern is the fact that breeding adults are potentially included in the harvest, and that the open season partially coincides with the breeding season. The present study has shown that although Montserrat is not a major nesting site for sea turtles, it remains important on a regional basis for the Eastern Caribbean.

    Full Text Available This study characterized the morphology of the digestive tube of five species of sea turtles. We used specimens found dead along the coast of the state Rio Grande do Norte, as well as specimens accidentally killed as a result of pelagic longline fishing. Nineteen animals of the following species were analyzed: Chelonia mydas (Linnaeus, 1758 (n = 9, Lepidochelys olivacea (Eschscholtz, 1829 (n = 6, Caretta caretta (Linnaeus, 1758 (n = 2, Eretmochelys imbricata (Linnaeus, 1766 (n = 1 and Dermochelys coriacea (Vandelli, 1761 (n = 1. After opening the plastron, we removed the digestive organs and described the external and internal morphology of each organ. The esophagus of all species had pointed papillae on the mucosa. The stomach varied in shape among species. Differences were found in the mucosa of the small intestine. It was reticular in the duodenum, and longitudinal rectilinear in the jejunum/ileum. In all species an alternation of saccular and narrow regions was observed in the large intestine. The exception was D. coriacea, in which the mucosa of the entire large intestine had irregularly distributed folds. The pattern of the esophagus was the same in all species. The morphology of the stomach differed among species, and these differences reflect their diets. In addition, the distribution pattern of the folds on the mucosa of the small intestine varied between regions of the intestine and among species.

  15. The role of turtles as coral reef macroherbivores.

    Christopher H R Goatley

    Full Text Available Herbivory is widely accepted as a vital function on coral reefs. To date, the majority of studies examining herbivory in coral reef environments have focused on the roles of fishes and/or urchins, with relatively few studies considering the potential role of macroherbivores in reef processes. Here, we introduce evidence that highlights the potential role of marine turtles as herbivores on coral reefs. While conducting experimental habitat manipulations to assess the roles of herbivorous reef fishes we observed green turtles (Chelonia mydas and hawksbill turtles (Eretmochelys imbricata showing responses that were remarkably similar to those of herbivorous fishes. Reducing the sediment load of the epilithic algal matrix on a coral reef resulted in a forty-fold increase in grazing by green turtles. Hawksbill turtles were also observed to browse transplanted thalli of the macroalga Sargassum swartzii in a coral reef environment. These responses not only show strong parallels to herbivorous reef fishes, but also highlight that marine turtles actively, and intentionally, remove algae from coral reefs. When considering the size and potential historical abundance of marine turtles we suggest that these potentially valuable herbivores may have been lost from many coral reefs before their true importance was understood.

    Prior to 2008 and the discovery of several important hawksbill turtle (Eretmochelys imbricata) nesting colonies in the EP (Eastern Pacific), the species was considered virtually absent from the region. Research since that time has yielded new insights into EP hawksbills, salient among them being the use of mangrove estuaries for nesting. These recent revelations have raised interest in the genetic characterization of hawksbills in the EP, studies of which have remained lacking to date. Between 2008 and 2014, we collected tissue samples from 269 nesting hawksbills at nine rookeries across the EP and used mitochondrial DNA sequences (766 bp) to generate the first genetic characterization of rookeries in the region. Our results inform genetic diversity, population differentiation, and phylogeography of the species. Hawksbills in the EP demonstrate low genetic diversity: We identified a total of only seven haplotypes across the region, including five new and two previously identified nesting haplotypes (pooled frequencies of 58.4% and 41.6%, respectively), the former only evident in Central American rookeries. Despite low genetic diversity, we found strong stock structure between the four principal rookeries, suggesting the existence of multiple populations and warranting their recognition as distinct management units. Furthermore, haplotypes EiIP106 and EiIP108 are unique to hawksbills that nest in mangrove estuaries, a behavior found only in hawksbills along Pacific Central America. The detected genetic differentiation supports the existence of a novel mangrove estuary "reproductive ecotype" that may warrant additional conservation attention. From a phylogeographic perspective, our research indicates hawksbills colonized the EP via the Indo-Pacific, and do not represent relict populations isolated from the Atlantic by the rising of the Panama Isthmus. Low overall genetic diversity in the EP is likely the combined result of few rookeries, extremely small

    Full Text Available Background: Marine turtles of all species are capable of being toxic. On 17 October 2010, health authorities in the Federated States of Micronesia were notified of the sudden death of three children and the sickening of approximately 20 other people on Murilo Atoll in Chuuk State. The illnesses were suspected to be the result of mass consumption of a hawksbill turtle (Eretmochelys imbricata. An investigation team was assembled to confirm the cause of the outbreak, describe the epidemiology of cases and provide recommendations for control. Methods: We conducted chart reviews, interviewed key informants, collected samples for laboratory analysis, performed environmental investigations and conducted a cohort study. Results: Four children and two adults died in the outbreak and 95 others were sickened; 84% of those who ate the turtle became ill (n = 101. The relative risk for developing illness after consuming the turtle was 11.1 (95% confidence inteval: 4.8–25.9; there was a dose-dependent relationship between amount of turtle meat consumed and risk of illness. Environmental and epidemiological investigations revealed no alternative explanation for the mass illness. Laboratory testing failed to identify a causative agent. Conclusion: We concluded that turtle poisoning (also called chelonitoxism was the cause of the outbreak on Murilo. The range of illness described in this investigation is consistent with previously reported cases of chelonitoxism. This devastating incident highlights the dangers, particularly to children, of consuming turtle meat. Future incidents are certain to occur unless action is taken to alter turtle-eating behaviour in coastal communities throughout the world.

    Full Text Available Chelonia marine turtle species preservation is one of the international community challenges through the world. In Congo-Brazzaville, the Renatura organization (ONG is engage to the biodiversity marine turtle species protection. Among the five of seven marine turtle species encountered in the coast, Turtle lute (Dermochelys coriacea; Green turtle (Chelonia mydas; Olive turtle (Lepidochelys olivacea; Turtle caouanne (Caretta caretta and Turtle overlapped (Eretmochelys imbricata. All these species of navy turtles well that protected by different international conventions, undergo several threats among which the nets and contraptions of traditional fishing constitute one of the main reasons of their decline. Indeed the accidental captures in the nets of the traditional fishers represent a serious threat for the navy turtles. This problem is delicate to manage because these holds don't depend directly on the will of the fishers. Indeed the turtles take themselves inauspiciously in the nets and entangle themselves of it while trying to clear itself/themselves of the net. To remedy this situation, Renatura Congo has, in 2005, initiated a program of liberation of the accidental captures of navy turtles in the nets of traditional fishing. About 1500 liberations are done annually by the agents of Renatura Congo. The liberation of these turtles doesn't constitute a long-term solution. Also, before the size of their accidental captures, it appeared to us necessary to bring our contribution in the survey of the nocuité of the contraptions and techniques of traditional fishing used to the bay of Loango in order to meter in evidence those that are more harmful. Such an objective reaches once, will allow us to improve these contraptions and techniques in order to reduce the risks of accidental captures while maintaining the level of the holds of fish and other aquatic organisms.

    This study analysed sea turtle strandings on the coast of Paraíba State, Northeastern Brazil, from August 2009 to July 2010. A total of 124 strandings were recorded in this period: green turtle Chelonia mydas (n = 106), hawksbill Eretmochelys imbricata (n = 15), olive ridley Lepidochelys olivacea (n = 2) and loggerhead Caretta caretta (n = 1). Of all turtles for which the Curved Carapace Length (CCL) was measured (n = 122), only 12 individuals (9.7%) were adults. Twenty individuals had synthetic anthropogenic debris in the gastrointestinal tract. Other traces of human interactions were observed in 43 individuals, such as injuries caused by entanglement in fishing lines or nets, collisions with vessels, direct contact with oil spills and lesions caused by sharp or spiked objects. Moreover, in 28.5% of the stranded turtles, the presence of external tumors was noticed, suggestive of fibropapillomatosis and in 9.7%, shark bite marks were observed. Of the 107 individuals that were sexed, 76 were females and 31 were males. Most turtles (72.6%) became stranded during the spring/summer (between October and March). We found evidence of human interactions (injuries) in half of the strandings, but in most cases it was not possible to determine if such interactions were the cause of death. A logistic regression found a significant relationship between CCL, ingestion of debris and lesions caused by sharks or spiked objects. Systematic data collection from stranded sea turtles can provide useful biological information, such as seasonal and spatial patterns in their occurrence and mortality, age structure, sex ratio and diet, as well as possible mortality causes.

    Assessment of population size and changes therein is important to sea turtle management and population or life history research. Investigators might be interested in testing hypotheses about the effect of current population size or density (number of animals per unit resource) on future population processes. Decision makers might want to determine a level of allowable take of individual turtles of specified life stage. Nevertheless, monitoring most stages of sea turtle life histories is difficult, because obtaining access to individuals is difficult. Although in-water assessments are becoming more common, nesting females and their hatchlings remain the most accessible life stages. In some cases adult females of a given nesting population are sufficiently philopatric that the population itself can be well defined. If a well designed tagging study is conducted on this population, survival, breeding probability, and the size of the nesting population in a given year can be estimated. However, with published statistical methodology the size of the entire breeding population (including those females skipping nesting in that year) cannot be estimated without assuming that each adult female in this population has the same probability of nesting in a given year (even those that had just nested in the previous year). We present a method for estimating the total size of a breeding population (including nesters those skipping nesting) from a tagging study limited to the nesting population, allowing for the probability of nesting in a given year to depend on an individual's nesting status in the previous year (i.e., a Markov process). From this we further develop estimators for rate of growth from year to year in both nesting population and total breeding population, and the proportion of the breeding population that is breeding in a given year. We also discuss assumptions and apply these methods to a breeding population of hawksbill sea turtles (Eretmochelys imbricata) from

    Full Text Available Accurately quantifying animals' spatial utilisation is critical for conservation, but has long remained an elusive goal due to technological impediments. The Argos telemetry system has been extensively used to remotely track marine animals, however location estimates are characterised by substantial spatial error. State-space models (SSM constitute a robust statistical approach to refine Argos tracking data by accounting for observation errors and stochasticity in animal movement. Despite their wide use in ecology, few studies have thoroughly quantified the error associated with SSM predicted locations and no research has assessed their validity for describing animal movement behaviour. We compared home ranges and migratory pathways of seven hawksbill sea turtles (Eretmochelys imbricata estimated from (a highly accurate Fastloc GPS data and (b locations computed using common Argos data analytical approaches. Argos 68(th percentile error was 4 km for LC ≤ 0. Argos error structure was highly longitudinally skewed and was, for all LC, adequately modelled by a Student's t distribution. Both habitat use and migration routes were best recreated using SSM locations post-processed by re-adding good Argos positions (LC 1, 2 and 3 and filtering terrestrial points (mean distance to migratory tracks ± SD = 2.2 ± 2.4 km; mean home range overlap and error ratio = 92.2% and 285.6 respectively. This parsimonious and objective statistical procedure however still markedly overestimated true home range sizes, especially for animals exhibiting restricted movements. Post-processing SSM locations nonetheless constitutes the best analytical technique for remotely sensed Argos tracking data and we therefore recommend using this approach to rework historical Argos datasets for better estimation of animal spatial utilisation for research and evidence-based conservation purposes.

    Marine debris is a growing problem for wildlife, and has been documented to affect more than 267 species worldwide. We investigated the prevalence of marine debris ingestion in 115 sea turtles stranded in Queensland between 2006-2011, and assessed how the ingestion rates differ between species (Eretmochelys imbricata vs. Chelonia mydas) and by turtle size class (smaller oceanic feeders vs. larger benthic feeders). Concurrently, we conducted 25 beach surveys to estimate the composition of the debris present in the marine environment. Based on this proxy measurement of debris availability, we modeled turtles' debris preferences (color and type) using a resource selection function, a method traditionally used for habitat and food selection. We found no significant difference in the overall probability of ingesting debris between the two species studied, both of which have similar life histories. Curved carapace length, however, was inversely correlated with the probability of ingesting debris; 54.5% of pelagic sized turtles had ingested debris, whereas only 25% of benthic feeding turtles were found with debris in their gastrointestinal system. Benthic and pelagic sized turtles also exhibited different selectivity ratios for debris ingestion. Benthic phase turtles had a strong selectivity for soft, clear plastic, lending support to the hypothesis that sea turtles ingest debris because it resembles natural prey items such as jellyfish. Pelagic turtles were much less selective in their feeding, though they showed a trend towards selectivity for rubber items such as balloons. Most ingested items were plastic and were positively buoyant. This study highlights the need to address increasing amounts of plastic in the marine environment, and provides evidence for the disproportionate ingestion of balloons by marine turtles.

  4. Factors affecting hatch success of hawksbill sea turtles on Long Island, Antigua, West Indies.

    Full Text Available Current understanding of the factors influencing hawksbill sea turtle (Eretmochelys imbricata hatch success is disparate and based on relatively short-term studies or limited sample sizes. Because global populations of hawksbills are heavily depleted, evaluating the parameters that impact hatch success is important to their conservation and recovery. Here, we use data collected by the Jumby Bay Hawksbill Project (JBHP to investigate hatch success. The JBHP implements saturation tagging protocols to study a hawksbill rookery in Antigua, West Indies. Habitat data, which reflect the varied nesting beaches, are collected at egg deposition, and nest contents are exhumed and categorized post-emergence. We analyzed hatch success using mixed-model analyses with explanatory and predictive datasets. We incorporated a random effect for turtle identity and evaluated environmental, temporal and individual-based reproductive variables. Hatch success averaged 78.6% (SD: 21.2% during the study period. Highly supported models included multiple covariates, including distance to vegetation, deposition date, individual intra-seasonal nest number, clutch size, organic content, and sand grain size. Nests located in open sand were predicted to produce 10.4 more viable hatchlings per clutch than nests located >1.5 m into vegetation. For an individual first nesting in early July, the fourth nest of the season yielded 13.2 more viable hatchlings than the initial clutch. Generalized beach section and inter-annual variation were also supported in our explanatory dataset, suggesting that gaps remain in our understanding of hatch success. Our findings illustrate that evaluating hatch success is a complex process, involving multiple environmental and individual variables. Although distance to vegetation and hatch success were inversely related, vegetation is an important component of hawksbill nesting habitat, and a more complete assessment of the impacts of specific

    Full Text Available Health, Healing and Shalom, Frontiers and Challenges for Christian Health Missions seeks to redress the compartmentalization and imbalance of spiritual versus physical care which plagues many in healthcare missions. It provides both a theological basis and practical ideas to enable healthcare missionaries to practice holistic care. Contributors have themselves practiced according to a definition of health as being a state of complete physical, mental, social and spiritual well-being, and not merely the absence of disease. A variety of specialized areas are presented, including short-term missions, Community Health Evangelism, HIV/AIDS, the impact of trauma, and palliative care. This should be exciting reading for those who wish to minister to the whole person, as Jesus did.

    In order to provide information to better inform management decisions and direct further research, vessel-based visual transects, snorkel transects, and in-water capture techniques were used to characterize hawksbill sea turtles in the shallow marine habitats of a Marine Protected Area (MPA), the Key West National Wildlife Refuge in the Florida Keys. Hawksbills were found in hardbottom and seagrass dominated habitats throughout the Refuge, and on man-made rubble structures in the Northwest Channel near Cottrell Key. Hawksbills captured (N = 82) were exclusively juveniles and subadults with a straight standard carapace length (SSCL) ranging from 21.4 to 69.0cm with a mean of 44.1 cm (SD = 10.8). Somatic growth rates were calculated from 15 recaptured turtles with periods at large ranging from 51 to 1188 days. Mean SSCL growth rate was 7.7 cm/year (SD = 4.6). Juvenile hawksbills (turtles yielded 12 haplotypes. Haplotype frequencies were significantly different compared to four other Caribbean juvenile foraging aggregations, including one off the Atlantic coast of Florida. Many-to-one mixed stock analysis indicated Mexico as the primary source of juveniles in the region and also suggested that the Refuge may serve as important developmental habitat for the Cuban nesting aggregation. Serum testosterone radioimmunoassay results from 33 individuals indicated a female biased sex ratio of 3.3 females: 1 male for hawksbills in the Refuge. This assemblage of hawksbills is near the northern limit of the species range, and is one of only two such assemblages described in the waters of the continental United States. Since this assemblage resides in an MPA with intensive human use, basic information on the assemblage is vital to resource managers charged with conservation and species protection in the MPA.

This assemblage of hawksbills is near the northern limit of the species range, and is one of only two such assemblages described in the waters of the continental United States. Since this assemblage resides in an MPA with intensive human use, basic information on the assemblage is vital to resource managers charged with conservation and species protection in the MPA.

    Somatic growth dynamics are an integrated response to environmental conditions. Hawksbill sea turtles (Eretmochelys imbricata) are long-lived, major consumers in coral reef habitats that move over broad geographic areas (hundreds to thousands of kilometers). We evaluated spatio-temporal effects on hawksbill growth dynamics over a 33-yr period and 24 study sites throughout the West Atlantic and explored relationships between growth dynamics and climate indices. We compiled the largest ever data set on somatic growth rates for hawksbills – 3541 growth increments from 1980 to 2013. Using generalized additive mixed model analyses, we evaluated 10 covariates, including spatial and temporal variation, that could affect growth rates. Growth rates throughout the region responded similarly over space and time. The lack of a spatial effect or spatio-temporal interaction and the very strong temporal effect reveal that growth rates in West Atlantic hawksbills are likely driven by region-wide forces. Between 1997 and 2013, mean growth rates declined significantly and steadily by 18%. Regional climate indices have significant relationships with annual growth rates with 0- or 1-yr lags: positive with the Multivariate El Niño Southern Oscillation Index (correlation = 0.99) and negative with Caribbean sea surface temperature (correlation = −0.85). Declines in growth rates between 1997 and 2013 throughout the West Atlantic most likely resulted from warming waters through indirect negative effects on foraging resources of hawksbills. These climatic influences are complex. With increasing temperatures, trajectories of decline of coral cover and availability in reef habitats of major prey species of hawksbills are not parallel. Knowledge of how choice of foraging habitats, prey selection, and prey abundance are affected by warming water temperatures is needed to understand how climate change will affect productivity of consumers that live in association with coral reefs.

    2005-07-01

    We report a case of dermatophytosis in a Judo wrestler caused by Trichophyton tonsurans (T. tonsurans) with clinical features that mimicked the concentric rings of tinea imbricata. Tinea imbricata is a unique dermatophytosis caused by Trichophyton concentricum (T. concentricum), observed endemically in subtropical to torrid zones and characterized by impressive concentric rings. We found three similar cases of the dermatophytosis in the literature that were reported as tinea pseudoimbricata or tinea indecisiva. All of these cases were associated with systemic or local immunosuppression, perhaps simulating the mechanism of tinea imbricata, which is known to involve the lack of delayed type hypersensitivity to T. concentricum. These cases imply that iatrogenic immunosuppression may perhaps play an important role in the development of the unique clinical features mimicking tinea imbricata. Furthermore, three of the four cases, including the presented case, were caused by T. tonsurans. It may be necessary to consider T. tonsurans infection when multiple concentric erythemas are encountered.

  8. Distinguishing suitable biotypes of Dactylopius tomentosus (Hemiptera: Dactylopiidae) for biological control of Cylindropuntia fulgida var. fulgida (Caryophyllales: Cactaceae) in South Africa.

    Cylindropuntia fulgida (Engelmann) F.M. Knuth var. fulgida (Engelmann) F.M. Knuth (Cff) (Caryophyllales: Cactaceae) is native to Mexico and Arizona and was introduced into South Africa for ornamental purposes. It subsequently became highly invasive, necessitating control. The cochineal insect, Dactylopius tomentosus (Lamarck) (Hemiptera: Dactylopiidae), was selected as a potential biological control agent based on its restricted host range among Cylindropuntia species and previous success in controlling C. imbricata (DC.) F. Knuth (Ci). Eight D. tomentosus provenances (Cholla, Cholla E, Fulgida, Mamillata, Imbricata, Tunicata U, Tunicata V and Rosea) from Cylindropuntia species in their native ranges were reared on Cff, whilst Cholla and Imbricata were also reared on Ci. Large differences were found in the development and survival of crawlers, and in the reproductive capacity of females. Three subjective categories of provenance interaction with host plants were identified based on a fitness index (FI) calculated from data relating to crawler survival, female development time and fecundity: (i) thriving (FI > or = 1) - insects had shorter developmental times, high crawler survival and highly fecund females (Cholla); (ii) surviving (FI0) - insects had extended development times, low crawler survival and low fecundity (Imbricata, Fulgida and Mamillata); and (iii) dying (FI = 0) - insects died before or at the second instar (Rosea, Tunicata U and Tunicata V). Cholla, therefore, is highly suitable for biological control of Cff in South Africa. In addition, Cholla thrived on Cff but only survived on Ci whilst, in contrast, Imbricata thrived on Ci but only survived on Cff. This differential ability of provenances to thrive or survive on different host plants demonstrated that host adapted biotypes of D. tomentosus exist; therefore, biotypes should be taken into account when considering this species as a biological control agent of cactus weeds.

    The general Reservoir Study of the Western Shallow Oil Zone was prepared by Evans, Carey and Crozier as Task Assignment 009 with the United States Department of Energy. This study, Appendix IV, addresses the Fourth Wilhelm Sand and its sub units and pools. Basic pressure, production and assorted technical data were provided by the US Department of Energy staff at Elk Hills. Basic pressure production and assorted technical data were provided by the US Department of Energy staff at Elk Hills. These data were accepted as furnished with no attempt being made by Evans, Carey and Crozier for independent verification. This study has identified the petrophysical properties and the past productive performance of the reservoir. Primary reserves have been determined and general means of enhancing future recovery have been suggested. It is hoped that this volume can now additionally serve as a take off point for exploitation engineers to develop specific programs toward the end. 12 figs., 9 tabs.

    Theories of how adults interpret the actions of others have focused on the goals and intentions of actors engaged in object-directed actions. Recent research has challenged this assumption, and shown that movements are often interpreted as being for their own sake (Schachner & Carey, 2013). Here we postulate a third interpretation of movement—movement that represents action, but does not literally act on objects in the world. These movements are gestures.

    1979-07-01

    Common belief in a vast oceanic Tethys is mistaken and results from attempts to reconstruct Pangaea on an Earth of constant dimensions. Tethys was an epicontinental sea, much longer than it was wide. India was simultaneously attached to Asia and formed part of Gondwanaland. This is possible only if, as Carey suggests, the Earth has expanded and the Indian Ocean formed as continents separated. Such separation was a single controlled event.

    During two cruises to the Gulf of Mexico and Caribbean Sea, some specimens of squat lobsters belonging to the genus Munidopsis Whiteaves, 1874 (family Munidopsidae Ortmann, 1898) were collected. The present collection comprises five species, where two are considered as new species: M. karukera, closely related to M. ariadne Macpherson, 2011, from the Mediterranean Sea; and M. tuerkayi, which resembles M. kareenae Ahyong, 2013, from New Zealand. The specimens were caught at six stations between 522 and 1162 m; some were associated with live cold-water corals, such as Lophelia pertusa (Linnaeus, 1758), Enallopsammia profunda (Pourtalès, 1867) and Candidella imbricata (Johnson, 1862).

    Five legume forages (Glycyrrhiza inflata, Glycyrrhiza pallidiflora , Oxytropis kansuensis, Oxytropis falcata, Oxytyopis imbricata ) were investigated in this study. Different scarification methods (cutting seed coats or immersing seeds with 98% sulfuric acid) for breaking seed dormancy were used. Results indicated that both impermeability and mechanical barrier of seed coat were key factors limiting seed germination. The germination rates of Glycyrrhiza inflata and Oxytropis kansuensis seeds were significantly improved with cutting seed coats or immersing in 98% sulfuric acid. The germination rates of Glycyrrhiza inflata and Oxytropis kansuensi reached 69% and 75% after immersing 98% sulfuric acid for 20 min or 5 min, respectively. The highest germination rate (93%) in Glycyrrhiza pallidi flora was obtained with seed coat pierced. Cutting seed coat was the optimal breaking seed dormancy method for both Oxytropis falcata and Oxytyopis imbricata and the 78% and 77% germination rates were obtained, respectively. The optimal temperature was at 30℃ for Oxytyopis imbricata seed germination and under 20℃ for other four tested seeds germinations.%对胀果甘草(Glycyrrhiza inflata Batalin)、刺果甘草(Glycyrrhiza pallidiflora Maxim)、甘肃棘豆(Oxytropis kansuensis Bunge)、镰形棘豆(Oxytropis falcata Bge)和密花棘豆(Oxytyopis imbricata Kom)5种豆科牧草进行萌发特性研究,采用打破硬实的方法如划破种皮、98%浓硫酸对种子处理,以期探讨其适宜的发芽条件.结果表明:通过切破种皮和浓硫酸处理可以有效地解除种子硬实.胀果甘草和甘肃棘豆分别经过98%的浓硫酸处理20min和5 min后,发芽率各自达到69%和75%(P<0.05);刺果甘草经过划破种皮,发芽率达到93%,是供试牧草种子中发芽率最高的;镰形棘豆和密花棘豆的适宜处理方法都是切破种皮,发芽率分别达到了78%和77%(P<0.01);对于5种牧草种子的温度

    Abstract Polystichum Roth is one of the largest and most taxonomically challenging fern genera. South American species have a rich and complex nomenclatural history; many of the early names are inadequately typified. Based on extensive examination of original type material, we designate eleven lectotypes (including Aspidium mohrioides, Aspidium montevidense f. imbricata, Aspidium montevidense f. squamulosa, Aspidium plicatum, Aspidium pycnolepis, Dicksonia andina, Polystichum elegans, Polystichum mohrioides f. latifolia, Polystichum multifidum var. autranii, Polystichum platyphyllum var. kurtziana, and Polypodium polystichoides), and one neotype (Polystichum brongniartianum) for Polystichum taxa. Furthermore, three new synonyms are proposed. PMID:27489490

    Objective: To investigate functional groups of toxic spines in stingray by Fourier transform infrared spectroscopic analysis.Methods:sephen were centrifuged at 6000 r/min for 10 min. The supernatant was collected and preserved separately in methanol, ethanol, chloroform, acetone (1:2) and then soaked in the mentioned solvents for 48 h. Then extracts were filtered and used for Fourier transform infrared spectroscopic analysis.Results:The venom extract of Himantura gerrardi, Himantura imbricata and Pastinachus and random coiled secondary structure.

    In this paper we mainly discuss the nonconforming finite element method for second order elliptic boundary value problems on anisotropic meshes. By changing the discretization form(i.e., by use of numerical quadrature in the procedure of computing the left load ), we obtain the optimal estimate O(h), which is as same as in the traditional finite element analysis when the load f∈H1(Ω)∩C0(Ω) which is weaker than the previous studies. The results obtained in this paper are also valid to the conforming triangular element and nonconforming Carey's element.

    Inclusive pion, kaon, proton, and antiproton production from proton-proton collisions is studied at a variety of proton energies. Various available parameterizations of Lorentz-invariant differential cross sections as a function of transverse momentum and rapidity are compared with experimental data. The Badhwar and Alper parameterizations are moderately satisfactory for charged pion production. The Badhwar parameterization provides the best fit for charged kaon production. For proton production, the Alper parameterization is best, and for antiproton production the Carey parameterization works best. However, no parameterization is able to fully account for all the data.

    Amphibian populations and species are declining or disappearing from many regions throughout the world (Stuart et al. 2004). No single cause has been demonstrated, although a number of emerging infectious diseases have been suggested as primary etiologic agents (Berger et al. 1998; Daszak et al. 2003; Lips et al. 2006). Several factors, including climate change, parasite infestation or compromised immune systems may interact locally or regionally to threaten species and populations (Carey and Bryant 1995; Parris and Beaudoin 2004; Pounds et al. 2006). Still, the disease model of amphibian decline may not be universally applicable (Daszak et al. 2005; McCallum 2005).

  2. Diagnostic Value of Run Chart Analysis: Using Likelihood Ratios to Compare Run Chart Rules on Simulated Data Series

    Science.gov (United States)

    Anhøj, Jacob

    2015-01-01

    Run charts are widely used in healthcare improvement, but there is little consensus on how to interpret them. The primary aim of this study was to evaluate and compare the diagnostic properties of different sets of run chart rules. A run chart is a line graph of a quality measure over time. The main purpose of the run chart is to detect process improvement or process degradation, which will turn up as non-random patterns in the distribution of data points around the median. Non-random variation may be identified by simple statistical tests including the presence of unusually long runs of data points on one side of the median or if the graph crosses the median unusually few times. However, there is no general agreement on what defines “unusually long” or “unusually few”. Other tests of questionable value are frequently used as well. Three sets of run chart rules (Anhoej, Perla, and Carey rules) have been published in peer reviewed healthcare journals, but these sets differ significantly in their sensitivity and specificity to non-random variation. In this study I investigate the diagnostic values expressed by likelihood ratios of three sets of run chart rules for detection of shifts in process performance using random data series. The study concludes that the Anhoej rules have good diagnostic properties and are superior to the Perla and the Carey rules. PMID:25799549

    Meditation is important in facilitating health. Pregnancy health has been shown to have significant consequences for infant behaviors. In view of limited studies on meditation and infant temperament, this study aims to explore the effects of prenatal meditation on these aspects. The conceptual framework was based on the postulation of positive relationships between prenatal meditation and infant health. A randomized control quantitative study was carried out at Obstetric Unit, Queen Elizabeth Hospital in Hong Kong. 64 pregnant Chinese women were recruited for intervention and 59 were for control. Outcome measures were cord blood cortisol, infant salivary cortisol, and Carey Infant Temperament Questionnaire. Cord blood cortisol level of babies was higher in the intervention group (pmeditation can influence fetal health. Carey Infant Temperament Questionnaire showed that the infants of intervention group have better temperament (pmeditation in relation to child health. Present study concludes the positive effects of prenatal meditation on infant behaviors and recommends that pregnancy care providers should provide prenatal meditation to pregnant women.

    Full Text Available Dermatophyte infection may present in the form of concentric rings caused by Trichophyton concentricum, known as Tinea Imbricata. In immunosuppressed patients, there are reports of lesions in the form of concentric rings caused by dermatophytes other than Trichophyton concentricum too, mostly by Trichophyton tonsurans, known as Tinea indesiciva or Tinea pseudoimbricata. We report a case of tinea capitis in a HIV-positive adult woman on antiretroviral therapy, who presented with concentric rings of papules and pustules with slight scaling on the scalp along with diffuse thinning of hair. Both Potassium hydroxide mount and culture showed the presence of Dermatophytes. Tinea capitis is considered rare in adults, but new cases are being reported in immunocompromised as well as in immunocompetent patients. The pertinent features of this case are: HIV-positive adult female on antiretroviral therapy, presenting with tinea capitis in the form of concentric rings; culture from the lesion grew Microsporum audouinii; responding to oral Terbinafine.

  6. Stable isotopes in bivalves as indicators of nutrient source in coastal waters in the Bocas del Toro Archipelago, Panama.

    2016-01-01

    To examine N-isotope ratios ((15)N/(14)N) in tissues and shell organic matrix of bivalves as a proxy for natural and anthropogenic nutrient fluxes in coastal environments, Pinctada imbricata, Isognomon alatus, and Brachidontes exustusbivalves were live-collected and analyzed from eight sites in Bocas del Toro, Panama. Sites represent a variety of coastal environments, including more urbanized, uninhabited, riverine, and oceanic sites. Growth under differing environmental conditions is confirmed by δ (18)O values, with open ocean Escudo de Veraguas shells yielding the highest average δ (18)O (-1.0‰) value and freshwater endmember Rio Guarumo the lowest (-1.7‰). At all sites there is no single dominant source of organic matter contributing to bivalve δ (15)N and δ (13)C values. Bivalve δ (15)N and δ (13)C values likely represent a mixture of mangrove and seagrass N and C, although terrestrial sources cannot be ruled out. Despite hydrographic differences between end-members, we see minimal δ (15)N and δ (13)C difference between bivalves from the river-influenced Rio Guarumo site and those from the oceanic Escudo de Veraguas site, with no evidence for N from open-ocean phytoplankton in the latter. Populated sites yield relative (15)N enrichments suggestive of anthropogenic nutrient input, but low δ (15)N values overall make this interpretation equivocal. Lastly, δ (15)N values of tissue and shell organic matrix correlate significantly for pterioideans P. imbricata and I. alatus. Thus for these species, N isotope studies of historical and fossil shells should provide records of ecology of past environments.

  7. E-Area Vault Concrete Material Property And Vault Durability/Degradation Projection Recommendations

    2014-03-11

    Subsequent to the 2008 E-Area Low-Level Waste Facility (ELLWF) Performance Assessment (PA) (WSRC 2008), two additional E-Area vault concrete property testing programs have been conducted (Dixon and Phifer 2010 and SIMCO 2011a) and two additional E-Area vault concrete durability modeling projections have been made (Langton 2009 and SIMCO 2012). All the information/data from these reports has been evaluated and consolidated herein by the Savannah River National Laboratory (SRNL) at the request of Solid Waste Management (SWM) to produce E-Area vault concrete hydraulic and physical property data and vault durability/degradation projection recommendations that are adequately justified for use within associated Special Analyses (SAs) and future PA updates. The Low Activity Waste (LAW) and Intermediate Level (IL) Vaults structural degradation predictions produced by Carey 2006 and Peregoy 2006, respectively, which were used as the basis for the 2008 ELLWF PA, remain valid based upon the results of the E-Area vault concrete durability simulations reported by Langton 2009 and those reported by SIMCO 2012. Therefore revised structural degradation predictions are not required so long as the mean thickness of the closure cap overlying the vaults is no greater than that assumed within Carey 2006 and Peregoy 2006. For the LAW Vault structural degradation prediction (Carey 2006), the mean thickness of the overlying closure cap was taken as nine feet. For the IL Vault structural degradation prediction (Peregoy 2006), the mean thickness of the overlying closure cap was taken as eight feet. The mean closure cap thicknesses as described here for both E-Area Vaults will be included as a key input and assumption (I&A) in the next revision to the closure plan for the ELLWF (Phifer et al. 2009). In addition, it has been identified as new input to the PA model to be assessed in the ongoing update to the new PA Information UDQE (Flach 2013). Once the UDQE is approved, the SWM Key I

  14. Failure to learn from feedback underlies word learning difficulties in toddlers at risk for autism.

    2013-01-01

    Children's assignment of novel words to nameless objects, over objects whose names they know (mutual exclusivity; ME) has been described as a driving force for vocabulary acquisition. Despite their ability to use ME to fast-map words (Preissler & Carey, 2005), children with autism show impaired language acquisition. We aimed to address this puzzle by building on studies showing that correct referent selection using ME does not lead to word learning unless ostensive feedback is provided on the child's object choice (Horst & Samuelson, 2008). We found that although toddlers aged 2;0 at risk for autism can use ME to choose the correct referent of a word, they do not benefit from feedback for long-term retention of the word-object mapping. Further, their difficulty using feedback is associated with their smaller receptive vocabularies. We propose that difficulties learning from social feedback, not lexical principles, limits vocabulary building during development in children at risk for autism.

    The purpose of this study was to research, develop and validate a one-semester course for the general education of university undergraduates in forensic chemical education. The course outline was developed using the research and development (R&D) methodology recommended by Gall, Borg, and Gall, (2003) and Dick and Carey, (2001) through a three step developmental cycle. Information was gathered and analyzed through review of literature and proof of concept interviews, laying the foundation for the framework of the course outline. A preliminary course outline was developed after a needs assessment showed need for such a course. Professors expert in the area of forensic science participated in the first field test of the course. Their feedback was recorded, and the course was revised for a main field test. Potential users of the guide served as readers for the main field test and offered more feedback to improve the course.

  1. International Perspectives of Ethical Approval: The New Zealand scene

    Directory of Open Access Journals (Sweden)

    Antoinette McCallin Ph.D.

    2010-12-01

    Full Text Available The paper “Navigating the process of ethical approval” (Carey, 2010 raises many issues about the influence Institutional Ethics Committees have on research methodology and what can or cannot take place in research. Carey draws attention to the ethical challenges classic grounded theory researchers face when an ethical proposal that follows the principles of the methodology is presented to an Ethics Committee, whose main responsibility is the protection of participants. Ethics committees not only guide researchers on acceptable ethical practice, but are charged with monitoring ethical standards and ensuring researchers act in accordance with professional expectations for researchers within the jurisdiction. These committees aim to ensure consistency of ethical practice in research. While there is generally some flexibility in the review process researchers often find ethical requirements constraining, as guidelines are primarily prescriptive and are designed to ensure consistency in the application of universal ethical principles in research. In New Zealand, consistency includes paying attention to broader socio-cultural responsibilities to society that includes promoting awareness of the Code of Health and Disability Services Consumer Rights 1996, the Health Information Privacy Code 1994, and promoting ethical practices which involve Maori (the local indigenous people in research proposals as much as possible (Ministry of Health, 2006. So while researchers in training assume that their prime interest concerns the management of a research topic and methodology, they quickly find out that ethical guidelines influence research design. Even though there is an international code of ethics (Universal Declaration of Human Rights, 2005 that defines ethical standards for researchers around the world, each country has its own specific requirements depending on the context. In this paper, ethical drivers in the New Zealand context are outlined and

  5. Contemplating the Future: Building Student Resilience in Climate Change Education

    Climate change research has largely focused on the biophysical, economic, and political aspects of the phenomenon, its projected impacts, and the possibilities for adaptation (Carey et al. 2014; Castree et al. 2014). In the classroom, too, climate change is generally presented as a scientific, technological, political, and economic challenge. However, defining climate change as physical challenge, divorced from its cultural causes and responses, forecloses some pathways of inquiry and limits the possibilities for adaptation (Adger et al. 2013). Recent perspectives by the environmental historian Mark Carey and colleagues (2014) and by the geographer Noel Castree and colleagues (2014) contend that ethnographic, narrative, social scientific, and humanistic insights are necessary additions to the climate change policy process and can contribute to deliberate, resilient responses to climate change. Among the humanistic insights needed are strategies and practices to maintain fortitude and persistence in the midst of dispiriting ecological trends. Students facing the "gloom and doom" of climate change data in environmental studies courses can experience negative states of mind such as denial, despair, burnout, and grief. Emerging research, however, demonstrates how contemplative practice can shift consciousness and promote resilience. Contemplative practices are those that consciously direct calm, focused attention. Such practices can build internal resilience, by promoting a greater sense of calm and well-being, decreasing stress, and sharpening focus and concentration. In addition, contemplative practices improve relationships with other people, through increasing compassion and flexibility in thinking. They also strengthen relationships with the surrounding world by increasing our ability to question, explore, and cope with rapid change and complexity. This presentation provides a context for incorporating contemplative practices, including mindfulness exercises

    This study sought to characterize temperament traits in a sample of children with autism spectrum disorder (ASD), ages 3-7 years old, and to determine the potential association between temperament and sensory features in ASD. Individual differences in sensory processing may form the basis for aspects of temperament and personality, and aberrations in sensory processing may inform why some temperamental traits are characteristic of specific clinical populations. Nine dimensions of temperament from the Behavioral Style Questionnaire (McDevitt and Carey in Manual for the behavioral style questionnaire, Behavioral-Developmental Initiatives, Scottsdale, AZ, 1996) were compared among groups of children with ASD (n = 54), developmentally delayed (DD; n = 33), and the original normative sample of typically developing children (McDevitt and Carey in J Child Psychol Psychiatr 19(3):245-253, 1978; n = 350) using an ANOVA to determine the extent to which groups differed in their temperament profiles. The hypothesized overlap between three sensory constructs (hyperresponsiveness, hyporesponsiveness, and seeking) and the nine dimensions of temperament was analyzed in children with ASD using regression analyses. The ASD group displayed temperament scores distinct from norms for typically developing children on most dimensions of temperament (activity, rhythmicity, adaptability, approach, distractibility, intensity, persistence, and threshold) but differed from the DD group on only two dimensions (approach and distractibility). Analyses of associations between sensory constructs and temperament dimensions found that sensory hyporesponsiveness was associated with slowness to adapt, low reactivity, and low distractibility; a combination of increased sensory features (across all three patterns) was associated with increased withdrawal and more negative mood. Although most dimensions of temperament distinguished children with ASD as a group, not all dimensions appear equally

    Life-history theory suggests that iteroparous plants should be flexible in their allocation of resources toward growth and reproduction. Such plasticity could have consequences for herbivores that prefer or specialize on vegetative versus reproductive structures. To test this prediction, we studied the response of the cactus bug (Narnia pallidicornis) to meristem allocation by tree cholla cactus (Opuntia imbricata). We evaluated the explanatory power of demographic models that incorporated variation in cactus relative reproductive effort (RRE; the proportion of meristems allocated toward reproduction). Field data provided strong support for a single model that defined herbivore fecundity as a time-varying, increasing function of host RRE. High-RRE plants were predicted to support larger insect populations, and this effect was strongest late in the season. Independent field data provided strong support for these qualitative predictions and suggested that plant allocation effects extend across temporal and spatial scales. Specifically, late-season insect abundance was positively associated with interannual changes in cactus RRE over 3 years. Spatial variation in insect abundance was correlated with variation in RRE among five cactus populations across New Mexico. We conclude that plant allocation can be a critical component of resource quality for insect herbivores and, thus, an important mechanism underlying variation in herbivore abundance across time and space.

    1. It is widely accepted that density-dependent processes play an important role in most natural populations. However, persistent challenges in our understanding of density-dependent population dynamics include evaluating the shape of the relationship between density and demographic rates (linear, concave, convex), and identifying extrinsic factors that can mediate this relationship. 2. I studied the population dynamics of the cactus bug Narnia pallidicornis on host plants (Opuntia imbricata) that varied naturally in relative reproductive effort (RRE, the proportion of meristems allocated to reproduction), an important plant quality trait. I manipulated per-plant cactus bug densities, quantified subsequent dynamics, and fit stage-structured models to the experimental data to ask if and how density influences demographic parameters. 3. In the field experiment, I found that populations with variable starting densities quickly converged upon similar growth trajectories. In the model-fitting analyses, the data strongly supported a model that defined the juvenile cactus bug retention parameter (joint probability of surviving and not dispersing) as a nonlinear decreasing function of density. The estimated shape of this relationship shifted from concave to convex with increasing host-plant RRE. 4. The results demonstrate that host-plant traits are critical sources of variation in the strength and shape of density dependence in insects, and highlight the utility of integrated experimental-theoretical approaches for identifying processes underlying patterns of change in natural populations.

  9. Herbivore-mediated ecological costs of reproduction shape the life history of an iteroparous plant.

    Plant reproduction yields immediate fitness benefits but can be costly in terms of survival, growth, and future fecundity. Life-history theory posits that reproductive strategies are shaped by trade-offs between current and future fitness that result from these direct costs of reproduction. Plant reproduction may also incur indirect ecological costs if it increases susceptibility to herbivores. Yet ecological costs of reproduction have received little empirical attention and remain poorly integrated into life-history theory. Here, we provide evidence for herbivore-mediated ecological costs of reproduction, and we develop theory to examine how these costs influence plant life-history strategies. Field experiments with an iteroparous cactus (Opuntia imbricata) indicated that greater reproductive effort (proportion of meristems allocated to reproduction) led to greater attack by a cactus-feeding insect (Narnia pallidicornis) and that damage by this herbivore reduced reproductive success. A dynamic programming model predicted strongly divergent optimal reproductive strategies when ecological costs were included, compared with when these costs were ignored. Meristem allocation by cacti in the field matched the optimal strategy expected under ecological costs of reproduction. The results indicate that plant reproductive allocation can strongly influence the intensity of interactions with herbivores and that associated ecological costs can play an important selective role in the evolution of plant life histories.

    This article describes biological hydrogen production from diary wastewater via anaerobic fermentation using pretreated heat shock (100 degrees Celsius, 30 min.) and acid (pH 3.0, 24 h) treatment procedures to selectively enrich the hydrogen producing mixed consortia prior to inoculation to batch reactors. Bioreactor used for immobilization consortia was operated at mesophilic (room) temperature (20{+-}3 degrees Celsius), under acidophilic conditions (pH 4.0-4.5), HRT (2h), and a natural support for generate hydrogen producing mixed consortia biofilm: Opuntia imbricata. Reactor was initially operated with sorbitol (5g/L) for 60 days of operation. Batch tests were conducted using 20{+-}0.02g of natural support with biofilm. Batch experiments were conducted to investigate the effect of COD (2.9-21.1 g-COD/L), at initial pH of 7.0, 32{+-}1 degrees Celsius. Maximum hydrogen yield was obtained at 21.1 g-COD/L. Experiments of pH effect were conducted using the optimal substrate concentration (21.2 g-COD/L), at pH 4 to 7 and 11.32 (pH diary wastewater) ,and 32{+-}1 degrees Celsius. Experiments results indicate the optimum initial cultivation was pH 4.0, but we can consider also a stable hydrogen production at pH 11.32 (pH diary wastewater), so we can avoid to fit the pH, and use diary wastewater as it left the process of cheese manufacture. The operational pH of 4.0 is 1.5 units below that of previously reported hydrogen producing organisms. The influence of the effect of temperature were conducted using the optimal substrate concentration (21.2 g-COD/L), two pH levels: 4.0 and 11.32, and four different temperatures: 16{+-}3 degrees Celsius (room temperature), 3 C, 45{+-}1 degrees Celsius y 55{+-}1 degrees Celsius.Optimal temperature for hydrogen production from diary wastewater at pH 4.0 was 55{+-}1 degrees Celsius, and for pH 11.32 was 16{+-}3 degrees Celsius.Therefore, the results suggests biofilm reactors in a natural support like Opuntia imbricata have good potential

  11. Up-regulated expression of AOS-LOXa and increased eicosanoid synthesis in response to coral wounding.

    Full Text Available In octocorals, a catalase-like allene oxide synthase (AOS and an 8R-lipoxygenase (LOX gene are fused together encoding for a single AOS-LOX fusion protein. Although the AOS-LOX pathway is central to the arachidonate metabolism in corals, its biological function in coral homeostasis is unclear. Using an acute incision wound model in the soft coral Capnella imbricata, we here test whether LOX pathway, similar to its role in plants, can contribute to the coral damage response and regeneration. Analysis of metabolites formed from exogenous arachidonate before and after fixed time intervals following wounding indicated a significant increase in AOS-LOX activity in response to mechanical injury. Two AOS-LOX isoforms, AOS-LOXa and AOS-LOXb, were cloned and expressed in bacterial expression system as active fusion proteins. Transcription levels of corresponding genes were measured in normal and stressed coral by qPCR. After wounding, AOS-LOXa was markedly up-regulated in both, the tissue adjacent to the incision and distal parts of a coral colony (with the maximum reached at 1 h and 6 h post wounding, respectively, while AOS-LOXb was stable. According to mRNA expression analysis, combined with detection of eicosanoid product formation for the first time, the AOS-LOX was identified as an early stress response gene which is induced by mechanical injury in coral.

    Plants belonging to the genus Maytenus are routinely used in folk medicine for the treatment of pain diseases. Our previous phytochemical study of the roots of Maytenus imbricata resulted in the isolation and characterization of tingenone, a pentacyclic triterpene. Natural triterpenoids are of growing interest because they have several biological activities, including analgesic properties. The present study assessed the involvement of the opiodergic pathway in the tingenone-induced antinociceptive effect against hyperalgesia induced by prostaglandin E2 (2 µg) in the peripheral pathway. We evaluated the effect of several antagonists to opioid receptors using the mouse paw pressure test. Tingenone administered into the right hind paw induced a local antinociceptive effect that was antagonized by naloxone, a nonselective antagonist to opioid receptors. Clocinnamox, naltrindole, and nor-binaltorphimine are selective antagonists to µ, δ, and κ receptors, respectively, which reverted the peripheral antinociception induced by tingenone. Bestatine acts as an inhibitor of aminopeptidase, an enzyme that degrades endogenous opioid peptides, and was shown to intensify the antinociceptive effect of tingenone. The results suggest that the opioidergic system participates in the peripheral antinociception induced by tingenone.

    Al-Samaliah Island is one of the inshore islands of U.A.E. located at about 12 km north-east of Abu Dhabi in the Arabian Gulf. It has a flat undulating surface with neither sand dunes nor rocky hills. Its sandy soil is generally salt-affected with variable percentages of salts. The vegetation of Al-Samaliah Island is essentially halophytic and may be categorized as: seagrasses, mangal and littoral saltmarsh types. The main species include: Cymodocea ciliata, Halophila spp. and Halodula univervis (seagrasses), some algae, Avicennia marina (mangrove), Arthrocnemum macrostachyum, Seidlitzia rosmarinus, and Suaeda vermiculata (salt marsh). Other halophytes commonly present are: Anabasis setifera, Halocnemum strobilaeum, Halopeplis perfoliata, Salsola imbricata and Zygophyllum gatarense in addition to two annuals: Schangenia aegyptiaca and Zygophyllum simplex. Phoenix dactylifera is cultivated in local areas covered with sandy sheets. Between the date palm trees there is a thin growth of Cyperus conglomeratus. Some plant species have been analysed chemically to determine their main constituents. The relationships between the environmental factors and the plant life of the islands are discussed.

    Full Text Available Nesting by three species of marine turtles persists in the Dominican Republic, despite historic threats and long-term population decline. We conducted a genetic survey of marine turtles in the Dominican Republic in order to link them with other rookeries around the Caribbean. We sequenced a 740bp fragment of the control region of the mitochondrial DNA of 92 samples from three marine turtle species [hawksbill (n = 48, green (n = 2 and leatherback (n = 42], and incorporated published data from other nesting populations and foraging grounds. The leatherback turtle (Dermochelys coriacea in the Dominican Republic appeared to be isolated from Awala-Yalimapo, Cayenne, Trinidad and St. Croix but connected with other Caribbean populations. Two distinct nesting populations of hawksbill turtles (Eremochelys imbricata were detected in the Dominican Republic and exhibited interesting patterns of connectivity with other nesting sites and juvenile and adult male foraging aggregations. The green sea turtle (Chelonia mydas has almost been extirpated from the Dominican Republic and limited inference could be made from our samples. Finally, results were compared with Lagrangian drifting buoys and published Lagrangian virtual particles that travelled through the Dominican Republic and Caribbean waters. Conservation implications of sink-source effects or genetic isolation derived from these complex inter-connections are discussed for each species and population.

    2002-01-01

    Thirty-three species of marine algae belonging to Rhodophyta, Phaeophyta and Chlorophyta from the Fujian coast were examined for agglutinins with different animal and human erythrocytes. Protein extracts from 26 species were active against at least one type of the erythrocytes tested. There were 3 species (Grateloupia imbricata, lshigefoliacea and Entermorpha prolifera) whose extracts could agglutinate all the erythrocytes used. The lowest protein concentration required to produce erythrocyte agglutination varied remarkably, from 3.1μg/ml to 500μg/ml . The strongest activity was found in the agglutina-tion of rabbit erythrocytes by Gloiopeltis furcata extract. Inhibition assays performed with nine mono- and bisaccharides indicated that agglutinations of rabbit erythrocytes by extracts of 7 species were inhibited by one or more types of the sugars assayed. The agglutinating activity shown by extracts of most species wasnot affected when the test solution was heated to 90℃, but was lost at 95℃ - 100℃. A few extracts losttheir activity at 60 RS, 65 RS and 75 RS, respectively.

    Full Text Available Taking (inauthenticity as his subject and intertextuality as the structuring principle, Peter Carey brings together Australian literary and social history, literary theory and a self-reflexive probe into the issues of identity, authenticity and cultural insecurity of a postcolonial society. The novel is interpreted as an allegorical account of national history and an allegorical narrative on the theoretical matters of originality and authorship.Keywords: Carey, identity, (inauthenticity, intertextuality, text, postcolonialism. The most well-known Australian author today, Peter Carey, has more than once found inspiration for his novels in already existing texts of British and Australian cultures. The most notable examples are his sixth novel titled Jack Maggs, his seventh novel titled True History of the Kelly Gang and the one explored in this paper, his eighth novel titled My Life as a Fake. Carey’s Jack Maggs (1997 retells the story of Dickens’ Great Expectations and in a postcolonial fashion of re-writing imperial texts gives voice to the previously marginalised point of view so that the story is told from the perspective of the runaway convict, Magwitch. The Booker Prize winning True History of the Kelly Gang (2001 is inspired by the so-called “Jerilderie letter,” which was written by Australia’s most famous outlaw, Ned Kelly, after a bank robbery in 1879. The fifty-six page long original letter is expanded in Carey’s version into thirteen parcels which actually make up this epistolary novel. My Life as a Fake (2003 is a roman a clef based on the literary hoax which took place in Melbourne in 1944 and assumed an Ossianic significance in the Australian literary establishment. Wishing to explore the depths of degradation which, in their opinion, Australian modernist poetry had reached, two young disgruntled poets, Harold Stewart and James McAuley, conjured up a fictitious poet, Ern Malley, a mechanic and the author of The Darkening

    Full Text Available E-Learning and Economic Development Kelly CAREY West Valley College Saratoga, CA, USA Stanko BLATNIK Institute for Symbolic Analysis and Development of Information Technologies Velenje, SLOVENIA ABSTRACT In this article, our experience in the development and realization of e-Learning courses in Slovenia is described and discussed. Slovenia, the most developed republic of former Yugoslavia, became an EU member in May 2004. In 1991, after its independence from Yugoslavia, Slovenia’s transition to a free market economy resulted in lost jobs and an unemployment rate of 12%. In 1999, as the Institute for Symbolic Analysis and Development of Information Technologies, located in Velenje, Slovenia, we decided to offer several online courses to help unemployed people gain the skills and knowledge needed for employability in information technology. We drew on our previous experience teaching online courses at Sarajevo University after the Bosnian war and on the experience of West Valley College from Saratoga, Silicon Valley in e-Learning. Over the last four years, we organized and delivered e-Learning courses in digital media design and production, with good results. Several students found jobs and changed their perception and attitude as they became more self-confident. We believe e-Learning can efficiently enhance lifelong learning and support economic development, especially in new member countries transitioning from former socialistic to free market economies.

    Full Text Available Immunization with DTP vaccine (diphtheria, tetanus and pertussis is a part of the vaccination calendar offered in childhood. Adverse allergic reactions vary from minimal urticarial reactions to life-threatening anaphylaxis. In infancy these reactions usually interrupt the vaccination calendar, but immunization in these children should be done. At the University Children's Hospital of Belgrade, a group of 137 children with suspected allergic anaphylactic reaction to DTP, DT, TT and monopertussis vaccine was studied for the last six years. Skin (prick and intradermal tests were performed with corresponding vaccine. If both tests were negative, the vaccine could be given as a single dose of 0.5 ml. If one of these tests were positive desensitization with vaccine could be done (according to the protocol described by Carey and Meltzer. In one group of 52 children three days before desensitization, premedication with antihistamines, was done, whereas in the other group of 52 children premedication was not done. Two (3.8% children in a group of 52 children with premedication had a minor (local reaction after vaccination and 50 children (96.2% had no reaction after vaccination, whereas no children (0% had systemic reaction after desensitization.

    Full Text Available This study aims to examine various aspects of religiosity in members of the Neocatechumenal Way and the Catholic Charismatic Renewal. First, we assigned intergroup differences in Emotions toward God, Religious Comfort and Strain and Religious Attributions. Next, we estimated the net effects of Emotions toward God, Religious Comfort and Strain and Religious Attributions on religiosity. One hundred fifty–five people participated in the research, 81 members of the Catholic Charismatic Renewal and 74 members of the Neocatechumenal Way. We applied the Religious Comfort and Strain Scale by Yali, Exline, Wood, and Worthington, the Emotions toward God Scale by Huber and the Religious Attributions Scale by Exline, Park, Smyth and Carey. The results suggest that members of the Neocatechumenal Way do not differ from the Catholic Charismatic Renewal’s members in Religious Comfort and Positive Emotions toward God. However, the members of the Neocatechumenal Way scored higher in Religious Strain. A moderating effect of the religious movement on the relation between Fear of God and religiosity was observed.

    Shelter dogs are typically cared for by staff and volunteers. At the Boston location of the Massachusetts Society for the Prevention of Cruelty to Animals, prior to 2009, any member of the public who was older than 16 years of age and attended 1 orientation could walk dogs available for adoption. There was no systematic method of training volunteers or staff to walk unruly, strong, or fearful dogs, nor was there any organized system of enrichment in the form of in-kennel or out-of-kennel training for the population of 20 to 40 dogs in the shelter. Using the Dick and Carey ( 1996 ) model of instructional design, a curriculum called "Safewalk" was devised and implemented. Safewalk created a hierarchical training system for volunteers. After training was implemented, outcomes and lengths of stay were then compared for dogs for the 3 years before and 4 years after Safewalk. Changes in adoption rates for pit bull-type dogs and non-pit bulls were significantly improved, and length of stay for non-pit bulls was significantly decreased. Other components of shelter life for dogs and people were also improved.

    Heavy rains in northwestern and north-central Ohio on August 19-22, 2007, caused severe flooding and widespread damages to residential, public, and commercial structures in the communities of Bluffton, Bucyrus, Carey, Columbus Grove, Crestline, Findlay, Mansfield, Ottawa, and Shelby. On August 27, 2007, the Federal Emergency Management Agency (FEMA) issued a notice of a Presidential declaration of a major disaster affecting Allen, Crawford, Hancock, Hardin, Putnam, Richland, Seneca, and Wyandot Counties as a result of the severe flooding. Rainfall totals for most of the flooded area were 3 to 5 in., with some locations reporting as much as 8 to 10 in. Three National Weather Service (NWS) gages in the area indicated a rainfall recurrence interval of greater than 1,000 years, and two indicated a recurrence interval between 500 and 1,000 years. Total damages are estimated at approximately $290 million, with 8,205 residences registering for financial assistance. The U.S. Geological Survey (USGS) computed flood recurrence intervals for peak streamflows at 22 streamgages and 8 ungaged sites in and around the area of major flooding. The peak streamflows at Sandusky River near Bucyrus streamgage and at seven of the eight ungaged sites had estimated recurrence intervals of greater than 500 years. The USGS located and surveyed 421 high-water marks and plotted high-water profiles for approximately 44.5 miles of streams throughout the nine communities.

  10. What is special about expertise? Visual expertise reveals the interactive nature of real-world object recognition.

    2016-03-01

    Ever since Diamond and Carey (1986. J. Exp. Psychol.: Gen., vol. 115, pp. 107-117) seminal work, the main model for studying expertise in visual object recognition ("visual expertise") has been face perception. The underlying assumption was that since faces may be considered the ultimate domain of visual expertise, any face-processing signature might actually be a general characteristic of visual expertise. However, while humans are clearly experts in face recognition, visual expertise is not restricted to faces and can be observed in a variety of domains. This raises the question of whether face recognition is in fact the right model to study visual expertise, and if not, what are the common cognitive and neural characteristics of visual expertise. The current perspective article addresses this question by revisiting past and recent neuroimaging and behavioural works on visual expertise. The view of visual expertise that emerges from these works is that expertise is a unique phenomenon, with distinctive neural and cognitive characteristics. Specifically, visual expertise is a controlled, interactive process that develops from the reciprocal interactions between the visual system and multiple top-down factors, including semantic knowledge, top-down attentional control, and task relevance. These interactions enable the ability to flexibly access domain-specific information at multiple scales and levels guided by multiple recognition goals. Extensive visual experience with a given object category culminates in the recruitment of these multiple systems, and is reflected in widespread neural activity, extending well beyond visual cortex, to include higher-level cortical areas.

    Carey and Friel suggest that we turn to knowledge developed in the field of public administration, especially new public governance, to better understand the process of implementing health in all policies (HiAP). In this commentary, I claim that theories from the policy studies bring a broader view of the policy process, complementary to that of new public governance. Drawing on the policy studies, I argue that time and ideas matter to HiAP implementation, alongside with interests and institutions. Implementing HiAP is a complex process considering that it requires the involvement and coordination of several policy sectors, each with their own interests, institutions and ideas about the policy. Understanding who are the actors involved from the various policy sectors concerned, what context they evolve in, but also how they own and frame the policy problem (ideas), and how this has changed over time, is crucial for those involved in HiAP implementation so that they can relate to and work together with actors from other policy sectors.

    2001-09-01

    Full Text Available Medie- og kommunikationsforskningen har ofte opfattet samtalen, der føres ansigt-til-ansigt, som en hjørnesten i den demokratiske proces. Denne opfattelse stammer bl.a. fra medieforskeren James Carey, der selv har været inspireret af den amerikanske filosof John Dewey. I den- ne artikel præsenterer Michael Schudson en kritik af, hvad han kalder den romantiske forestilling om samtalen. Samtalen ansigt-til-ansigt har været lige så meget i højsædet i aristokratier som i demokratier, og der er faktisk to distinkte og modsatte idealer for samtale: den selskabelige samtale og den problemløsende samtale. Samtalen, der tjener demo- kratiet, er ikke kendetegnet ved egalitarisme, men ved normstyrethed og offentlighed, ikke ved spontanitet men ved høflighed, og ikke ved dens forrang eller overlegenhed i forhold til trykte medier, radio eller tv, men ved dens nødvendige afhængighed af dem. Der argumenteres for, at institutioner og demokratiske normer giver anledning til demokratiske samtaler, snarere end at samtalens iboende demokrati fører til politisk demokratiske normer og institutioner.

Mingle as a technique in teaching speaking proposed by Pollard and Hess in 1997 was developed into a new model. Using ADDIE model as proposed by Dick and Carey in 1996, we collected the intended data through observation, questionnaire, and test. The result of the research showed that the implementation of model gave a significant difference in term of the students-learning outcome between the students who are taught through Mingle model and by traditional one or without Mingle model. The development of Mingle model included preparation, warming up, set the rule, act Mingle model, presentation, review and discussion. It is concluded that Mingle model is more effective to improve students on all components of speaking skill. Therefore, it is recommended that this model can be implemented at IAIN Imam Bonjol Padang. Copyright © 2015 by Al-Ta'lim All right reserved

    2015-07-14

    Although the biochemical processes of lipid digestion are well-known, the biophysical ones, responsible for the assembly of molecules into functional structures, lack studies resolving both time and space scales. About 35 years ago, the seminal microscopy study of Patton and Carey constituted a major advance to reach this goal. Nowadays, new perspectives arise from the availability of large facilities scattering techniques, able to monitor the dynamics of multi-scale assemblies with unprecedented resolutions. The present small angle X-ray scattering (SAXS) study focused on the roles of the emulsifier and triglyceride in the formation of lipid assemblies during emulsion digestion in vitro. By developing several interpretations of the data in the whole space range (qualitative, shape-dependent and shape-independent models), the characteristic size of the assemblies and their transition times were obtained, which depended on the triglyceride, but not on the emulsifier. The major assembly formed was found to be a spherical mixed micelle, but vesicle was also found to coexist throughout the digestion, although in a lower proportion. The quantitative determination of the sizes and proportions of these assemblies, as well as the evolution of these characteristics during digestion are precious information for nutritional sciences, as these assemblies are the vehicles of lipophilic nutrients and micronutrients towards their absorption site.

    Preparations of 2.0 and 5.5 wt % sodium dodecyl sulfate (SDS) in 3.5 wt % (0.6 M) aqueous NaCl are equilibrium micellar solutions above 28/sup 0/C, the Krafft point of the surfactant at this salinity. These systems can be supercooled and remain transparent for hours and days. At 25/sup 0/C at equilibrium they are biphasic, a hydrated crystal phase and an aqueous salt solution phase containing only 0.01/sub 2/ wt % SDS. Conductimetry and /sup 13/C NMR show that these transparent supercooled systems are indeed supersaturated solutions and not microdispersions of the hydrated crystal. The time lag for the onset of nucleation of the crystals depends strongly on stirring details and probably on presence of gas-liquid interface. The big nonequilibrium aggregates present in the supersaturated systems resemble micelles in conductivity and molecular motion, and are likely to be metastable micelles as is presumed by Mazer, Benedek, and Carey. 21 references, 6 figures, 1 table.

    We develop by example a type of index theory for non-Fredholm operators. A general framework using cyclic homology for this notion of index was introduced in a separate article (Carev and Kaad, Topological invariance of the homological index. arXiv:1402.0475 [math.KT], 2014) where it may be seen to generalise earlier ideas of Carey-Pincus and Gesztesy-Simon on this problem. Motivated by an example in two dimensions in Bollé et al. (J Math Phys 28:1512-1525, 1987) we introduce in this paper a class of examples of Dirac type operators on that provide non-trivial examples of our homological approach. Our examples may be seen as extending old ideas about the notion of anomaly introduced by physicists to handle topological terms in quantum action principles, with an important difference, namely, we are dealing with purely geometric data that can be seen to arise from the continuous spectrum of our Dirac type operators.

    Phantom of the Universe is a planetarium show premiering in 2016 that will showcase an exciting exploration of dark matter, from the Big Bang to the Large Hadron Collider. The show will reveal the first hints of its existence through the eyes of Fritz Zwicky. Viewers will marvel at the astral choreography witnessed by Vera Rubin in the Andromeda galaxy. They will plummet deep underground to see the most sensitive dark matter detector on Earth. From there, they will end the journey at the Large Hadron Collider, speeding alongside particles before they collide in visually stunning explosions of light and sound, and learning how scientists around the world are collaborating to track down the constituent of dark matter. The show will be offered to planetariums worldwide free of charge. It will feature music composed by Mickey Hart (Apocalypse Now, The Twilight Zone, The Grateful Dead) and narration by Academy-Award winning actress Tilda Swinton, and showcase the creativity and directing prowess of Joao Pequenao and the writing and producing talents of award-winning filmmaker, Carey Ann Strelecki.

    自詹姆斯·凯瑞提出传播的仪式观以来,文化模式的新闻生产研究经历了人类学朝社会学视维转向的过程。通过文化视维看近期中国的交通事故报道,新闻生产可被理解为普世叙事倾向与本土文化资源的双重作用。然而文化模式尚未解答叙事倾向的形成、冲突与社会互动等深层问题,布尔迪厄对“习性”的阐述对此提供了理论参考。%After James Carey proposed a ritual view of communication in 1975, studies about news production based on cultural models underwent an epistemological tum from anthropology to sociology. By examining some traffic accident news reports in Chinese media recently, the cultural vision of news production defines the news as the products of journalists' universal narrative dispositions and local cultural resources. While the cultural vision has not yet addressed the formation, conflicts and social interaction of narrative disposition, Bourdieu's concept ofhabitus provides a theoretical reference for those questions

Drawing on the policy studies, I argue that time and ideas matter to HiAP implementation, alongside with interests and institutions. Implementing HiAP is a complex process considering that it requires the involvement and coordination of several policy sectors, each with their own interests, institutions and ideas about the policy. Understanding who are the actors involved from the various policy sectors concerned, what context they evolve in, but also how they own and frame the policy problem (ideas), and how this has changed over time, is crucial for those involved in HiAP implementation so that they can relate to and work together with actors from other policy sectors.

    2001-03-01

    The micromagnetic theory of antiferromagnetically coupled magnetic recording media (AFC media) is discussed for the case of AFC media consisting of two ferromagnetic layers and a polarization layer.[1-2] Attention is focused on AFC media where the top layer governs the remanent magnetization while the bottom layer acts as a slave layer. Micromagnetic simulations of recorded bit transitions demonstrate a good anticorrelation of the layer magnetizations at bit transitions for this case. Calculation of MR readback pulses shows that these AFC media have pulse widths of a thin single layer magnetic recording medium with an effective MrT that is approximately given by the difference in MrT's of the top and bottom layers. Magnetic stability is set to first order by the thicker top layer and the interactions between the top and bottom layers. [1] E.E. Fullerton, D.T. Margulies, M.E. Schabes, M. Carey, B. Gurney, A.

    The combination of signal-to-noise requirements, write field limitations, and thermal activation of small particles is thought to limit the potential areal density of longitudinal media and is commonly referred to as the "superparamagnetic limit". Recording media composed of antiferromagnetically coupled (AFC) magnetic recording layers is a promising approach to extend areal densities of longitudinal media beyond these perceived limits [1,2]. The recording medium is made up of two ferromagnetic recording layer separated by a nonmagnetic layer whose thickness is tuned to couple the layers antiferromagnetically. For such a structure, the effective areal moment density (Mrt) of the composite structure is given by the difference between the ferromagnetic layers allowing the effective magnetic thickness to scale independently of the physical thickness of the media. The resulting media appears magnetically thin while being physically thick and, thus, allows AFC media to maintain thermal stability even for low Mrt values. Experimental realization of this concept using CoPtCrB alloy layers that demonstrates thermally stable low-Mrt media suitable for high-density recording will be discussed. This work is done in collaboration with D. T. Margulies, M. E. Schabes,M. Doerner, M. Carey, B. Gurney, A. Moser, M. Best, G. Zeltzer, K. Rubin, and H. Rosen. [1]. Fullerton et al., Appl. Phys.

    The bubble N4 was observed as part of the Herschel infrared Galactic Plane Survey (Hi-GAL) survey. In this survey, the Photodetector Array Camera & Spectrometer (PACS) at 70 and 160um and the Spectral and Photometric Imaging Receiver (SPIRE) at 250, 350, and 500um worked simultaneously in the parallel photometric mode. The measured angular resolutions of these bands are 10.7", 13.9", 23.9", 31.3", and 43.8" (Traficante et al. 2011MNRAS.416.2932T), respectively. Single-dish observations of molecular lines were performed with the Korean VLBI Network (KVN) 21m radio telescope at Yonsei site, Seoul on 2014 December 28. The front end of the single-dish telescope is equipped with four receivers working at 22, 43, 86, and 129GHz simultaneously. To study the physical characteristics of the bubble and its associated YSO candidates, auxiliary data of images and point sources were complemented by the GLIMPSE (Benjamin et al. 2003PASP..115..953B), MIPSGAL (Carey et al. 2009PASP..121...76C) and WISE (Wright et al. 2010AJ....140.1868W) surveys. The images of the Spitzer Infrared Array Camera (IRAC) at 3.6, 4.5, 5.8, and 8.0um, together with the Multiband Imaging Photometer for Spitzer (MIPS) at 24um were retrieved from the Spitzer Archive. The angular resolutions of the images in the IRAC bands are MIPS 24um band. (2 data files).

    Previous studies indicate that English-learning children acquire the distinction between singular and plural nouns between 22 and 24 months of age. Also, their use of the distinction is correlated with the capacity to distinguish nonlinguistically between singular and plural sets in a manual search paradigm (D. Barner, D. Thalwitz, J. Wood, S. Yang, & S. Carey, 2007). The authors used 3 experiments to explore the causal relation between these 2 capacities. Relative to English, Japanese and Mandarin had impoverished singular-plural marking. Using the manual search task, in Experiment 1 the authors found that by around 22 months of age, Japanese children also distinguished between singular and plural sets. Experiments 2 and 3 extended this finding to Mandarin-learning toddlers. Mandarin learners who were 20-24 months of age did not yet comprehend Mandarin singular-plural marking (i.e., yige vs. yixie, or -men), yet they did distinguish between singular and plural sets in manual search. These experiments suggest that knowledge of singular-plural morphology is not necessary for deploying the nonlinguistic distinction between singular and plural sets.

    Unlike many brain injured children who are often rather difficult, toddlers and school-aged children with congenital vein of Galen malformations (n = 20; age range, 4 months to 12 years with a mean of 4 years) evidence a relatively positive temperament profile (based on the Temperament Scales of Carey, McDevitt, Fullard, Hegvik, Medoff-Cooper). They do not, however, differ from normal children with regard to the frequency of easy, difficult, slow to warm up, and intermediate temperament clusters. The temperament profile of children with vein of Galen malformations appears unaffected by additional neurologic abnormalities (hydrocephalus, abnormal developmental quotient, seizure disorder, focal cortical lesions) or other factors including age at testing, sex, or socioeconomic status. Contrary to the findings in adults of right hemisphere dominance for attention, presence of additional right-sided focal cortical pathology was not associated with greater activity level, distractibility, or impersistence. In contrast to the findings in adults and children of right hemisphere dominance for emotions in general, children with vein of Galen malformations and additional right hemisphere cortical damage are not more difficult than those with additional left cortical pathology or no additional focal cortical pathology. The fact that the pathology in vein of Galen malformations is subcortical may explain their relatively easier temperament and the absence of lateralization effects.

    Observations of the infrared dust bubble N6 in J=1-0 transitions of 12CO (115.272 GHz) and 13CO (110.201 GHz) were carried out with the Purple Mountain Observatory (PMO) 13.7m telescope on 2012 June 29. The on-the-fly mode was used to map a 21'x25' region with a reference point at RA(J2000)=18 14 39.3, DE(J2000)=-18 24 42.9. The half-power beam width of the PMO 13.7 m telescope was about 52" at both 115GHz and 110GHz. The pointing and tracking accuracies were determined to be better than 5" by scanning planets (e.g., Jupiter and Venus). Public survey data at wavelengths ranging from infrared to centimeter were retrieved from GLIMPSE (Cat. II/293), MIPSGAL (Carey et al., 2009PASP..121...76C), and MAGPIS (Cat. J/AJ/131/2525) surveys.

    The purpose of this pilot study was to evaluate developmental neuropsychological profiles of 4- to 5-year-old children born after Preimplantation Genetic Diagnosis (PGD). Twenty-seven participants received a neurological examination and a battery of neuropsychological assessments including Wechsler Preschool & Primary Scale of Intelligence - Third Edition (WPPSI-III; cognitive development), Preschool Language Scale, Fourth Edition (PLS-4; language development), Wide Range Assessment of Visual Motor Abilities (visual motor abilities), Childhood Autism Rating Scales II (a screening test for autistic spectrum disorders), and the Miles ABC Test (ocular dominance). Parental questionnaires included the Behavior Rating Inventory of Executive Function Preschool Version (BRIEF-P; executive function), Child Behavior Checklist (CBCL) and the Carey Temperament Scales Behavioral Style Questionnaire (socioemotional development and temperament), and the Vineland Adaptive Behavior Scales, Interview Edition, Second Edition (general adaptive behavior). Subjects' tests results were compared to each test's norms. Children born after PGD demonstrated scores within the normal or above-normal ranges for all developmental outcomes (mean ± SD): WPPSI-III-VIQ 107.4 ± 14.4 (p = .013), PLS-4-Total 113.2 ± 12.4, p family history of autism was noted. In conclusion, in this pilot study, children assessed at age 4-5 years and conceived after PGD displayed developmental neuropsychological outcomes within normal limits as compared to their chronologic peers. A larger study is needed to evaluate and follow the neuropsychological development of children born after PGD.

  16. Unifying Paschen Curve Conditions across Pressure and Gap Distance

    2015-11-01

    The Paschen curve (PC) predicts the breakdown voltage of a gas by relating it to the product of pressure and gap distance (pd). Recent experiments deviate from the PC for microscale gaps at low pd. A scaling law incorporating field emission-driven breakdown and field enhancement to the macroscale Paschen law yields more accurate predictions for microscale gaps (A. Venkattraman and A. A. Alexeenko, Phys. Plasmas 19, 123515 (2012).). While many studies consider low pd, deviations from the PC also arise at high pd, as demonstrated for gap distances between 0.0508 and 0.254 cm and pressures between 96.5 and 6900 kPa (W. J. Carey, A. J. Wiebe, R. D. Nord, and L. L. Altgilbers, in Proc. IEEE Pulsed Power Conf., 2011, pp. 741-744). High pd values are relevant for ongoing high voltage plasma experiments for food treatment and combustion. We attempt to elucidate the impact of large gap distances (~ 5 cm) and higher pressures (~ 200-300 kPa) on these deviations by connecting recent work at low pd to high pd by assessing scaling laws, analyzing field emission models, and using particle-in-cell codes. Implications on experimental design will be discussed, and the development of a universal Paschen curve will be explored.

    In corals a catalase-lipoxygenase fusion protein transforms arachidonic acid to the allene oxide 8R,9-epoxy-5,9,11,14-eicosatetraenoic acid from which arise cyclopentenones such as the prostanoid-related clavulones. Recently we cloned two catalase-lipoxygenase fusion protein genes (a and b) from the coral Capnella imbricata, form a being an allene oxide synthase and form b giving uncharacterized polar products (Lõhelaid, H., Teder, T., Tõldsepp, K., Ekins, M., and Samel, N. (2014) PloS ONE 9, e89215). Here, using HPLC-UV, LC-MS, and NMR methods, we identify a novel activity of fusion protein b, establishing its role in cleaving the lipoxygenase product 8R-hydroperoxy-eicosatetraenoic acid into the short-chain aldehydes (5Z)-8-oxo-octenoic acid and (3Z,6Z)-dodecadienal; these primary products readily isomerize in an aqueous medium to the corresponding 6E- and 2E,6Z derivatives. This type of enzymatic cleavage, splitting the carbon chain within the conjugated diene of the hydroperoxide substrate, is known only in plant cytochrome P450 hydroperoxide lyases. In mechanistic studies using 18O-labeled substrate and incubations in H218O, we established synthesis of the C8-oxo acid and C12 aldehyde with the retention of the hydroperoxy oxygens, consistent with synthesis of a short-lived hemiacetal intermediate that breaks down spontaneously into the two aldehydes. Taken together with our initial studies indicating differing gene regulation of the allene oxide synthase and the newly identified catalase-related hydroperoxide lyase and given the role of aldehydes in plant defense, this work uncovers a potential pathway in coral stress signaling and a novel enzymatic activity in the animal kingdom.

    Using GPS technology and community research methods for plant communities,we investigated the distribution patterns of aquatic plant communities in the high plateaus of the Napahai Wetlands,Yunnan,China,as well as the species changes of plant communities compared with that of 24 years ago since 2005.We found that the types and numbers of aquatic plant communities have changed.Some pollution-tolerant,nutrient-loving plant communities such as Scirpus tabernaemontani,Zizania caduciflora,Myriophyllum spicatum,and Azolla imbricata flourished,while the primary aquatic plant com-munities were reduced or even disappeared.The number of aquatic plant communities were increased from nine to 12 with the addition of two new emergent plant com-munities and one new floating-leaved plant community.The increase in emergent plant communities was signifi-cant.From east to west and from south to north,various types of plant communities were continuously distributed,including floating-leaved plant communities,emergent plant communities and submerged plant communities.The composition of the communities became more com-plicated and the number of accompanying species increased,while the percentage ratio of dominant plant species declined.In 2005,the coverage of emergent plant communities was the largest (528.42 hm2) followed by submerged plant communities (362.50 hm2) and the float-ing-leaf plant communities was the smallest (70.23 hm2).The variations in the distribution of aquatic plant com-munities in the Napahai Wetlands reflect the natural responses to the change of the wetland ecological envir-onment.This study indicates that human disturbances have led to an inward movement of the wetland shoreline,a decrease in water quality and a reduction in wetland habitat.

    Although recent molecular studies have indicated the presence of a number of distinct species within the Caulerpa racemosa-peltata complex, due to the difficulties presented by high levels of phenotypic plasticity and the large number of synonyms, infra-specific taxa, and names of uncertain affinity, taxonomic proposals are yet to be made. In this study, we aimed to resolve the taxonomy of the complex and provide an example of how historical nomenclature can best be integrated into molecular based taxonomies. We accomplished this by first determining the number of genetic species within our globally sampled data set through a combination of phylogenetic and species-delimitation approaches of partial elongation factor TU and RUBISCO large subunit gene sequences. Guided by these results, comparative morphological examinations were then undertaken to gauge the extent of phenotypic plasticity within each species, as well as any morphological overlap between them. Our results revealed the presence of 11 distinct species within the complex, five of which showed high levels of phenotypic plasticity and partial overlap with other species. On the basis of observations of a large number of specimens, including type specimens/descriptions, and geographic inferences, we were able to confidently designate names for the lineages. Caulerpa peltata, C. imbricata and C. racemosa vars. laetevirens, occidentalis and turbinata were found to represent environmentally induced forms of a single species, for which the earlier-described C. chemnitzia, previously regarded as a synonym of C. racemosa var. turbinata, is reinstated. C. cylindracea, C. lamourouxii, C. macrodisca, C. nummularia and C. oligophylla are also reinstated and two new species, C. macra stat. nov. and C. megadisca sp. nov., are proposed.

    Marine ecosystems are sensitive to elevated seawater temperature, with stony corals serving as model organisms for temperature-imposed declines in population viability and diversity. Several stress markers, including heat shock proteins, have been used for the detection and prediction of stress responses in stony corals. However, the stress indicators in soft corals remain elusive. In higher animals and plants, oxylipins synthesized by fatty acid di- and monooxygenases contribute to stress-induced signaling; however, the role of eicosanoid pathways in corals remains unclear. The eicosanoid gene specific to corals encodes for a natural fusion protein of allene oxide synthase and lipoxygenase ( AOS- LOX). In this work, using the easily cultivated soft coral Capnella imbricata as the stress response model, we monitored the expression of the AOS-LOX and the formation of arachidonic acid metabolites in response to an acute rise in water temperature. Gene expression profiles of two 70 kDa heat shock proteins ( Hsps: Hsp70 and Grp78) were used as a positive control for the stress response. In comparison with normal seawater temperature (23 °C), AOS- LOXa and Hsps were all up-regulated after modest (28 °C) and severe (31 °C) temperature elevation. While the up-regulation of AOS- LOXa and Grp78 was more sensitive to moderate temperature changes, Hsp70s were more responsive to severe heat shock. Concurrently, endogenous and exogenous AOS-LOXa-derived eicosanoids were up-regulated. Thus, together with the up-regulation of AOS- LOX by other abiotic and biotic stress stimuli, these data implicate AOS-LOX as part of the general stress response pathway in corals.

The remaining beetle species aggregated with one to four other hispines. Adults of C. belti and C. championi were frequently seen, occasionally also with C. dilaticollis, C. histrionica, and Chelobasis perplexa, to co-occur with the carabid Calophaena ligata in the same leaf roll without any sign of interspecific aggression.A comparison of host choices and the phylogeny of the hispines and of their host plants revealed no signs that beetles used species level phylogenetic relationships within the Zingiberales to food plants. Obviously, within this plant order, rolled-leaf hispines choose their plant hosts in a nearly opportunistic manner. Seemingly, they use differences among plants at higher taxonomic levels but within the Zingiberales, the availability of

    A total of 301 adult hispine beetles of the genera Cephaloleia and Chelobasis were found in rolled leaves of plants of 17 species of Zingiberales (families Costaceae, Heliconiaceae, Maranthaceae, Musaceae, and Zingiberaceae) during a field study at La Gamba, Golfito region, Costa Rica. Of these beetles, Cephaloleia belti was recorded from 12 potential host plant species, C. distincta from 7, C. dilaticollis from 5, C., Chelobasis bicolor, C. championi, and C. histrionica from 3, Chelobasis perplexa and C. instabilis from 2, whereas C. trivittata from only one. Of the plant species, Heliconia latispatha had 7 beetle species in its leaf rolls, Calathea lutea had 5, H. imbricata and H. rostrata had 4, H. stricta and Musa paradisiaca had 3, H. wagneriana had 2, while on H. vaginalis, H. danielsiana, H. densiflora, H. longiflora, Calathea crotalifera, C. platystachya, Goeppertia lasiophylla, Alpinia purpurata, Costus pulverulentus and Costus barbatus, H. densiflora, H. vaginalis, and H. danielsana only hispines of one species were found. Cephaloleia belti occurred together with beetles of six other hispine species, whereas Cephaloleia trivittata never shared a leaf roll with another hispine species.

    Full Text Available The article covers some information on anthropogenic influence upon natural ecosystems that is considered to be one of the strongest factors for reducing biodiversity of Georgian flora. With this purpose, some species of fam. Iridaceae that need to be protected under in situ conditions are being studied. The paper focuses on the fam. Iridaceae. This family is particularly interesting as it unites a considerable number of valuable, beautifully flowering plants with ornamental leaves, representing different biomorphs. Particularly rare and endangered species are: Iris iberica, I. Grossheimii, I. Lycotis, I. Camillae, I. Elegantissima, etc. We have carried out complex studies of bio-ecological peculiarities of bulbous geophytes and ephemeroids of genus Iridodictyum winogradowii, Ir. Reticulatum, Siphonastilis lasica and Iuno caucasica. There has been studied rhythm of growth and development of vital cycle of monocarpic shootings and ways of their propagation in the sub arid zone of East Georgia. There should be mentioned that they have perfectly adapted to the conditions. Such rare species of rootstock plants like Iris iberica, I. Carthalinical. Aphylla, I. graminea, I. imbricata, I. timofejewii, I. prilipkoana, I. musulmanica, Siphonastilis lazica and others even give abundant self-seedlings that undoubtedly makes it possible to protect them from being finally extinct. All the investigated plants can be recommended for using in landscape architecture under the conditions of East Georgia that will contribute to conservation of the valuable genofond of relict and endemic plants of Georgian flora. The work deals with the results of in situ conservation of some of rare and endemic species of fam. Iridaceae from Iridaceae Juss family. According to IUCN categories, the studied taxaare discussed as the endangered species in nature.

  9. Oroclines - a century of discourse about curved mountain belts (Petrus Peregrinus Medal Lecture)

    Science.gov (United States)

    Van der Voo, Rob

    2014-05-01

    Exactly a century ago, in early 2014, a discussion appeared in the Journal of Geology by William H. Hobbs entitled "Mechanics of formation of arcuate mountains". In it, he notes how the concept of nappes "has now overcome all opposition in Switzerland" and, presumably in other countries just as much. With horizontal transport so central to the nappe concept, this must have paved the way for the idea that emplacement of trust sheets may have involved rotations. Where such rotations form a coherent regional pattern, a curved mountain belt may be the result. While the paper by Hobbs does not mention the word orocline, and while the dynamics of the situation is not yet illuminated, one must give credit to him for his foresights. The term "orocline" was introduced by S. Warren Carey of Tasmania in 1955, as part of a kinematic analysis of rhomb- and triangle-shaped basins and curved mountain belts. When the displacements involved in the analysis are undone, as he did, for instance, in the western Mediterranean, a grand scheme of simple convergent and divergent patterns emerges. Noteworthy is, of course, the fact that this mobilistic analysis preceded plate tectonics by more than a decade. From Carey (although not exactly in his words) we have inherited the definition of orocline, as "a thrust belt or orogen that is curved in map-view due to it having been bent or buckled about a vertical axis of rotation". Because oroclinal bending involves rotations, the declinations of paleomagnetic studies can be utilized to support and quantify them, and early efforts were already made in the 1960's and early 1970's to do so (e.g., Krs in the Carpathians; Ries & Shackleton in Cantabria; Roy, Opdyke & Irving in the Central Appalachians; Packer & Stone in Alaska). Curved mountain belts everywhere were subsequently investigated, and typically shown by paleomagnetists to be of the oroclinal variety. Few curved belts turned out to be curved from the start. Because these studies were

    Full Text Available Students enter the library science graduate program with a wide range of information and technology skills. Today’s graduate courses require students to be able to build web-based pathfinders, use social media, and search databases. This article examines the design and development of an introductory course for incoming library science graduate students that personalizes instruction and ensures that each student is ready for the rigors of graduate school. Taken during the first semester of the program, this introductory course teaches information and technology skills and concepts that are core to library science. The author explores the process of creating a computer-based course that addresses the diverse needs of this student population. Using a systematic approach to instructional design and development, the author outlines the steps in designing, developing, implementing, and evaluating an online, self-paced graduate course. Based on the Dick and Carey model, the process included identifying the instructional goals, conducting an instructional analysis, analyzing learners and contexts, writing performance objectives, developing assessment instruments, developing instructional strategies, developing and selecting instructional materials, designing and conducting formative evaluation of instruction, revising instruction, and designing and conducting summative evaluation. This process produced effective, efficient, and appealing instructional materials.

    Students are typically introduced to the relative motions of plates and its effects either through text-based descriptions, paper models, or both. However, though students may learn to repeat the description of the effects, many students still do not show a deeper understanding of the process, as shown by examinations of students before and after an introductory geology course (DeLaughter et al, 1998). This is because students are rarely affected by the information on a visceral level; because their preconceptions are never challenged, they never internalize the information as part of their model of how the world works. However, when concepts such as plate motions and their effects are presented to students as part of a tangible, physical experiment, the ideas can have a much greater impact (Carey et al, 1989). The students use the new information to build more complete mental models while learning that such models can and must change in response to new information (Herbert, 2003). When such experiments are performed in a geology class, they afford the students a direct and visceral experience that may enhance the learning process. In this exercise for middle school students, the effects of relative plate motions on overlying sediments are modeled through a simple and inexpensive set of experiments using sand and newspaper. These experiments provide qualitatively the same results as those performed by geologists researching various aspects of faulting and folding (e.g., Horsfield, 1977, Domingez et al., 2000). A secondary benefit of these experiments is that when the students do not pull the papers perfectly the combination of effects can mimic real terrains (e.g., transpressional) very closely. This intrusion of methodological errors can also lead to a lively discussion of how science is done and what the results of an experiment imply, thereby providing a pedagogical benefit as well. Thus students can be shown the effects of relative plate motions in a direct and

  13. The heat capacity of hydrous cordierite above 295 K

    Carey, J. William

    1993-04-01

    The heat capacity of synthetic hydrous cordierite (Mg2Al4Si5O18·nH2O) has been determined by differential scanning calorimetry (DSC) from 295 to 425 K as a function of H2O content. Six samples with H2O contents ranging from 0 to 0.82 per formula unit were examined. The partial molar heat capacity of H2O in cordierite over the measured temperature interval is independent of composition and temperature within experimental uncertainty and is equal to 43.3 ±0.8 J/mol/ K. This value exceeds the molar heat capacity of gaseous H2O by 9.7 J/mol/K, but is significantly smaller than the heat capacity of H2O in several zeolites and liquid H2O. A statistical-mechanical model of the heat capacity of adsorbed gas species (Barrer 1978) is used to extrapolate the heat capacity of hydrous cordierite to temperatures greater than 425 K. In this model, the heat capacity of hydrous cordierite (Crd·nH2O) is represented as follows: Cp(Crd · nH2O) = Cp(Crd)+ n{Cp(H2O, gas)+ R(gas constant)} (1) An examination of calorimetric data for hydrous beryl, analcime, mordenite, and clinoptilolite (Hemingway et al. 1986; Johnson et al. 1982, 1991, 1992) demonstrates the general applicability of the statistical-mechanical model for the extrapolation of heat capacity data of zeolitic minerals. The heat capacity data for cordierite are combined with the data of Carey and Navrotsky (1992) to obtain the molar enthalpy of formation and enthalpy of hydration of hydrous cordierite as a function of temperature.

    Full Text Available What is the relation between humans and nonhuman animals? From a biological perspective, we view humans as one species among many, but in the fables and films we create for children, we often offer an anthropocentric perspective, imbuing nonhuman animals with human-like characteristics. What are the consequences of these distinctly different perspectives on children’s reasoning about the natural world? Some have argued that children universally begin with an anthropocentric perspective and that acquiring a biological perspective requires a basic conceptual change (cf. Carey 1985. But recent work reveals that this anthropocentric perspective, evidenced in urban five-year-olds, is not evident in three-year-olds (Herrmann et al. 2010. This indicates that the anthropocentric perspective is not an obligatory first step in children’s reasoning about biological phenomena. In the current paper, we introduced a priming manipulation to assess whether five-year-olds’ reasoning about a novel biological property is influenced by the perspectives they encounter in children’s books. Just before participating in a reasoning task, each child read a book about bears with an experimenter. What varied was whether bears were depicted from an anthropomorphic (Berenstain Bears or biological perspective (Animal Encyclopedia. The priming had a dramatic effect. Children reading the Berenstain Bears showed the standard anthropocentric reasoning pattern, but those reading the Animal Encyclopedia adopted a biological pattern. This offers evidence that urban five-year-olds can adopt either a biological or a human-centered stance, depending upon the context. Thus, children’s books and other media are double-edged swords. Media may (inadvertently support human-centered reasoning in young children, but may also be instrumental in redirecting children’s attention to a biological model.

However the influence of dietary supplemented n-3-LC-PUFAs on inflammation-related cell death and proliferation after middle cerebral artery occlusion (MCAo-induced stroke is unknown. We have previously demonstrated that anxiety-like and hyperactive locomotor behaviors are reduced in n-3-LC-PUFA-fed MCAo animals. Thus in the present study, male hooded Wistar rats were exposed to MCAo or sham surgeries and examined behaviorally 6 weeks later, prior to euthanasia and examination of lesion size, cell death and proliferation in the dentate gyrus, cornu ammonis region of the hippocampus of the ipsilesional hemispheres, and the thalamus of the ipsilesional and contralesional hemispheres. Markers of cell genesis and cell degeneration in the hippocampus or thalamus of the ipsilesional hemisphere did not differ between surgery and diet groups 6 weeks post MCAo. Dietary supplementation with n-3-LC-PUFA decreased cell degeneration and increased cell proliferation in the thalamic region of the contralesional hemisphere. MCAo–associated cell degeneration in the hippocampus and thalamus positively correlated with anxiety-like and hyperactive locomotor behaviors previously reported in these animals. These results suggest that anti-inflammatory n-3-LC-PUFA supplementation appears to have cellular protective effects after MCAo in the rat, which may affect behavioral outcomes.

There is also increasing evidence that male partner involvement positively impacts non-HIV related outcomes, such as skilled attendance at delivery, exclusive breastfeeding, uptake of effective contraceptives, and infant immunizations. Despite these associations, male partner involvement remains low, especially when offered in the standard antenatal clinic setting. In this review we explore strategies for improving rates of antenatal male partner HIV testing and argue that the role of male partners in PMTCT must evolve from one of support for HIV-infected pregnant and breastfeeding women to one of comprehensive engagement in prevention of primary HIV acquisition, avoidance of unintended pregnancies, and improved HIV-related care and treatment for the HIV-infected and uninfected women, their partners, and children. Involving men in all components of PMTCT has potential to contribute substantially to achieving virtual elimination of mother-to-child HIV transmission; promoting partner-friendly programs and policies, as well as pursuing research into numerous gaps in knowledge identified in this review, will help drive this process.

  18. What makes a movement a gesture?

    2016-01-01

    Theories of how adults interpret the actions of others have focused on the goals and intentions of actors engaged in object-directed actions. Recent research has challenged this assumption, and shown that movements are often interpreted as being for their own sake (Schachner & Carey, 2013). Here we postulate a third interpretation of movement-movement that represents action, but does not literally act on objects in the world. These movements are gestures. In this paper, we describe a framework for predicting when movements are likely to be seen as representations. In Study 1, adults described one of three scenes: (1) an actor moving objects, (2) an actor moving her hands in the presence of objects (but not touching them) or (3) an actor moving her hands in the absence of objects. Participants systematically described the movements as depicting an object-directed action when the actor moved objects, and favored describing the movements as depicting movement for its own sake when the actor produced the same movements in the absence of objects. However, participants favored describing the movements as representations when the actor produced the movements near, but not on, the objects. Study 2 explored two additional features-the form of an actor's hands and the presence of speech-like sounds-to test the effect of context on observers' classification of movement as representational. When movements are seen as representations, they have the power to influence communication, learning, and cognition in ways that movement for its own sake does not. By incorporating representational gesture into our framework for movement analysis, we take an important step towards developing a more cohesive understanding of action-interpretation.

  19. Explanations, mechanisms, and developmental models: Why the nativist account of early perceptual learning is not a proper mechanistic model

    Directory of Open Access Journals (Sweden)

    Radenović Ljiljana

    2013-01-01

    Full Text Available In the last several decades a number of studies on perceptual learning in early infancy have suggested that even infants seem to be sensitive to the way objects move and interact in the world. In order to explain the early emergence of infants’ sensitivity to causal patterns in the world some psychologists have proposed that core knowledge of objects and causal relations is innate (Leslie & Keeble 1987, Carey & Spelke, 1994; Keil, 1995; Spelke et al., 1994. The goal of this paper is to examine the nativist developmental model by investigating the criteria that a mechanistic model needs to fulfill if it is to be explanatory. Craver (2006 put forth a number of such criteria and developed a few very useful distinctions between explanation sketches and proper mechanistic explanations. By applying these criteria to the nativist developmental model I aim to show, firstly, that nativists only partially characterize the phenomenon at stake without giving us the details of when and under which conditions perception and attention in early infancy take place. Secondly, nativist start off with a description of the phenomena to be explained (even if it is only a partial description but import into it a particular theory of perception that requires further empirical evidence and further defense on its own. Furthermore, I argue that innate knowledge is a good candidate for a filler term (a term that is used to name the still unknown processes and parts of the mechanism and is likely to become redundant. Recent extensive research on early intermodal perception indicates that the mechanism enabling the perception of regularities and causal patterns in early infancy is grounded in our neurophysiology. However, this mechanism is fairly basic and does not involve highly sophisticated cognitive structures or innate core knowledge. I conclude with a remark that a closer examination of the mechanisms involved in early perceptual learning indicates that the nativism

    Chrysotile-containing joint compound was commonly used in construction of residential and commercial buildings through the mid 1970s; however, these products have not been manufactured in the United States for more than 30 years. Little is known about actual human exposures to chrysotile fibers that may have resulted from use of chrysotile-containing joint compounds, because few exposure and no health-effects studies have been conducted specifically with these products. Because limited amounts of historical joint compounds are available (and the stability or representativeness of aged products is suspect), it is currently impossible to conduct meaningful studies to better understand the nature and magnitude of potential exposures to chrysotile that may have been associated with historical use of these products. Therefore, to support specific exposure and toxicology research activities, two types of chrysotile-containing joint compounds were produced according to original formulations from the late 1960s. To the extent possible, ingredients were the same as those used originally, with many obtained from the original suppliers. The chrysotile used historically in these products was primarily Grade 7RF9 from the Philip Carey mine. Because this mine is closed, a suitable alternate was identified by comparing the sizes and mineral composition of asbestos structures in a sample of what has been represented to be historical joint compound (all of which were chrysotile) to those in samples of three currently commercially available Grade 7 chrysotile products. The re-created materials generally conformed to original product specifications (e.g. viscosity, workability, crack resistance), indicating that these materials are sufficiently representative of the original products to support research activities.

  2. On World Religion Adherence Distribution Evolution

    Ausloos, Marcel; Petroni, Filippo

    Religious adherence can be considered as a degree of freedom, in a statistical physics sense, for a human agent belonging to a population. The distribution, performance and life time of religions can thus be studied having in mind heterogeneous interacting agent modeling. We present a comprehensive analysis of 58 so-called religions (to be better defined in the main text) as measured through their number of adherents evolutions, between 1900 and 2000, - data taken from the World Christian Trends (Barrett and Johnson, "World Christian Trends AD 30 - AD 2200: Interpreting the Annual Christian Megacensus", William Carey Library, 2001): 40 are considered to be "presently growing" cases, including 11 turn overs in the twentieth century; 18 are "presently decaying", among which 12 are found to have had a recent maximum, in the nineteenth or the twentieth century. The Avrami-Kolmogorov differential equation which usually describes solid state transformations, like crystal growth, is used in each case in order to obtain the preferential attachment parameter introduced previously (Europhys Lett 77:38002, 2007). It is not often found close to unity, though often corresponding to a smooth evolution. However large values suggest the occurrence of extreme cases which we conjecture are controlled by so-called external fields. A few cases indicate the likeliness of a detachment process. We discuss a few growing and decaying religions, and illustrate various fits. Some cases seem to indicate the lack of reliability of the data, but others some marked departure from Avrami law. Whence the Avrami evolution equation might be surely improved, in particular, and somewhat obviously, for the decaying religion cases. We point out two major difficulties in such an analysis: (1) the "precise" original time of apparition of a religion, (2) the time at which there is a maximum number of adherents, both information being necessary for integrating reliably any evolution equation.

    Previous research has addressed the issues of behavior change and eating disorder prevention among adolescents and young women. The current study was designed to evaluate: (a) whether an 8-week psychoeducational intervention can reduce maladaptive weight-management practices in women (University females, N=24) with sub-clinical levels of eating pathology; and (b) whether its implementation reduces the risk of developing more severe eating pathology across time. Participants were randomly assigned to an experimental (EX) group or a self-monitoring control (SMC) group. Statistically significant changes on measures of eating pathology, including the Eating Attitudes Test-26 [Garner, D. M., Olmsted, M. P., Bohr, Y., & Garfinkel, P. (1982). The Eating Attitudes Test: psychometric features and clinical correlates. Psychological Medicine, 12, 871-878]; Forbidden Food Survey [Ruggerio, L., Williamson, D. A., Davis, C. J., Schlundt, D. G., & Carey, M. P. (1988). Forbidden Food Survey: Measure of bulimic's anticipated emotional reactions to specific foods. Addictive Behaviors, 13, 267-274]; and Bulimia Test-Revised [Thelen, M. H., Farmer, J., Wonderlich, S., & Smith, M. (1991). A revision of the bulimia test: The BULIT-R. Journal of Consulting and Clinical Psychology, 3(1), 119-124] were observed, as were changes in body image, as measured by the Body Shape Questionnaire [Cooper, P. J., Taylor, M. J., Cooper, Z., & Fairburn, C. G. (1987). The development and validation of the body shape questionnaire. International Journal of Eating Disorders, 6(4), 485-494]. Additional significant between-group differences in eating behavior, as measured by daily meal records, were also seen. Participants in the EX group evidenced improvements in scores which were significantly different from those observed in the SMC group. Unfortunately, attrition limited the utility of follow up data.

    流行歌坛有靓音有人说流行歌曲是一半靠听、一半靠看的音乐,因为从严格意义上说,它不再是纯粹的音乐,而象歌剧一样需要(事实上比歌剧更需要)借助视觉效果。流行歌曲演唱会如果不亲临其境而只听录音,味道肯定大打折扣。尽管如此,当今的流行歌坛还是不乏以声音动人而不是以动作、以外在形象动人的歌手。早先的卡伦·卡彭特、芭芭拉·史翠姗、惠竺尼·休斯顿等公认的金嗓子,当今走红的玛莉亚·凯瑞(Mariah Carey)、席琳·迪翁(Celine Dion)等都在此列。但在我心目中,流行歌坛上最完美的男声却毫无疑问属于西班牙人胡里奥·伊格莱西亚斯(Julio Iglesias)。人们常说西班牙出了两大民族英雄:男高音歌唱家卡雷拉斯和大歌星胡里奥。其实照我看后者的成就更在前者之上。且不说胡里

  5. Computational studies of two-phase cement-CO2-brine interaction in wellbore environments

    2009-01-01

    Wellbore integrity is essential to ensuring long-term isolation of buoyant supercritical CO{sub 2} during geologic sequestration of CO{sub 2}. In this report, we summarize recent progress in numerical simulations of cement-brine-CO{sub 2} interactions with respect to migration of CO{sub 2} outside of casing. Using typical values for the hydrologic properties of cement, caprock (shale) and reservoir materials, we show that the capillary properties of good quality cement will prevent flow of CO{sub 2} into and through cement. Rather, CO{sub 2}, if present, is likely to be confined to the casing-cement or cement-formation interfaces. CO{sub 2} does react with the cement by diffusion from the interface into the cement, in which case it produces distinct carbonation fronts within the cement. This is consistent with observations of cement performance at the CO{sub 2}-enhanced oil recovery SACROC Unit in West Texas (Carey et al. 2007). For poor quality cement, flow through cement may occur and would produce a pattern of uniform carbonation without reaction fronts. We also consider an alternative explanation for cement carbonation reactions as due to CO{sub 2} derived from caprock. We show that carbonation reactions in cement are limited to surficial reactions when CO{sub 2} pressure is low (< 10 bars) as might be expected in many caprock environments. For the case of caprock overlying natural CO{sub 2} reservoirs for millions of years, we consider Scherer and Huet's (2009) hypothesis of diffusive steady-state between CO{sub 2} in the reservoir and in the caprock. We find that in this case, the aqueous CO{sub 2} concentration would differ little from the reservoir and would be expected to produce carbonation reaction fronts in cements that are relatively uniform as a function of depth.

  8. Humans (really) are animals: picture-book reading influences 5-year-old urban children's construal of the relation between humans and non-human animals.

    What is the relation between humans and non-human animals? From a biological perspective, we view humans as one species among many, but in the fables and films we create for children, we often offer an anthropocentric perspective, imbuing non-human animals with human-like characteristics. What are the consequences of these distinctly different perspectives on children's reasoning about the natural world? Some have argued that children universally begin with an anthropocentric perspective and that acquiring a biological perspective requires a basic conceptual change (cf. Carey, 1985). But recent work reveals that this anthropocentric perspective, evidenced in urban 5-year-olds, is not evident in 3-year-olds (Herrmann etal., 2010). This indicates that the anthropocentric perspective is not an obligatory first step in children's reasoning about biological phenomena. In the current paper, we introduced a priming manipulation to assess whether 5-year-olds' reasoning about a novel biological property is influenced by the perspectives they encounter in children's books. Just before participating in a reasoning task, each child read a book about bears with an experimenter. What varied was whether bears were depicted from an anthropomorphic (Berenstain Bears) or biological perspective (Animal Encyclopedia). The priming had a dramatic effect. Children reading the Berenstain Bears showed the standard anthropocentric reasoning pattern, but those reading the Animal Encyclopedia adopted a biological pattern. This offers evidence that urban 5-year-olds can adopt either a biological or a human-centered stance, depending upon the context. Thus, children's books and other media are double-edged swords. Media may (inadvertently) support human-centered reasoning in young children, but may also be instrumental in redirecting children's attention to a biological model.

Patients and methods: In April 2014, patients attending our rheumatology service for infliximab infusions were switched from reference product to the biosimilar infliximab following consent and hospital approval. Results: Around 34 patients with inflammatory arthritis were switched from reference product to biosimilar infliximab in 2014: 50% female, mean age 55 years (standard deviation=12.9, mean disease duration 14.79 years (9.7, median duration on infliximab 57 months, and two-thirds on oral disease-modifying antirheumatic drugs. There was no difference in efficacy or safety in the first 6 months of therapy. By the end of 2015, the mean follow-up on biosimilar infliximab was 15.8 (standard deviation=6.3 months. Our results showed no significant difference in Health Assessment Questionnaire score, patient global assessment of disease activity, number of disease flares, or the medication dose between the originator and the biosimilar infliximab. However, reported pain and C-reactive protein values were significantly higher during the longer follow-up period (p=0.043, 0.001 respectively. There was no significant difference in the number of adverse events or infusion reactions during follow-up periods. Only five (14.7% patients discontinued the biosimilar infliximab. Conclusion: Our patients experienced similar efficacy and safety for managing their arthritis with the biosimilar infliximab as the reference product infliximab, but at a much lower cost.

  11. GEODYNAMIC WAVES AND GRAVITY

    2015-09-01

    Full Text Available  Gravity phenomena related to the Earth movements in the Solar System and through the Galaxy are reviewed. Such movements are manifested by geological processes on the Earth and correlate with geophysical fields of the Earth. It is concluded that geodynamic processes and the gravity phenomena (including those of cosmic nature are related.  The state of the geomedium composed of blocks is determined by stresses with force moment and by slow rotational waves that are considered as a new type of movements [Vikulin, 2008, 2010]. It is shown that the geomedium has typical rheid properties [Carey, 1954], specifically an ability to flow while being in the solid state [Leonov, 2008]. Within the framework of the rotational model with a symmetric stress tensor, which is developed by the authors [Vikulin, Ivanchin, 1998; Vikulin et al., 2012a, 2013], such movement of the geomedium may explain the energy-saturated state of the geomedium and a possibility of its movements in the form of vortex geological structures [Lee, 1928]. The article discusses the gravity wave detection method based on the concept of interactions between gravity waves and crustal blocks [Braginsky et al., 1985]. It is concluded that gravity waves can be recorded by the proposed technique that detects slow rotational waves. It is shown that geo-gravitational movements can be described by both the concept of potential with account of gravitational energy of bodies [Kondratyev, 2003] and the nonlinear physical acoustics [Gurbatov et al., 2008]. Based on the combined description of geophysical and gravitational wave movements, the authors suggest a hypothesis about the nature of spin, i.e. own moment as a demonstration of the space-time ‘vortex’ properties.

    Full Text Available We estimated the nutritive value, vitamin content, amino acid composition, fatty acid content, and mineral profile of a phytococktail comprising sea buckthorn (Hippophae rhamnoides, apricot (Prunus armeniaca, and roseroot (Rhodiola imbricata from trans-Himalaya. The free vitamin forms in the phytococktail were determined by rapid resolution liquid chromatography/tandem mass spectrometry (RRLC-MS/MS. Vitamin E and B-complex vitamins were detected as the principle vitamins. Reversed-phase high performance liquid chromatography (RP-HPLC with pre-column derivatization was used for identification and quantification of amino acids. Eight essential and eleven non-essential amino acids were quantified, and the content ranged between 76.33 and 9485.67 µg/g. Among the essential amino acids, L-methionine, L-phenylalanine, L-lysine, L-leucine, and L-histidine were found to be the dominant contributors. We also quantified the fatty acids in the phytococktail by using gas chromatography coupled with a flame ionization detector (GC-FID with fatty acid methyl esters (FAMEs derivatization. The analysis revealed the presence of 4 major fatty acids contributing to the total lipid content. Palmitic acid was found to be the rich source of saturated fatty acid (SFA and constituted ∼31% of the total lipid content. Among the unsaturated fatty acids (UFAs, palmitoleic acid (43.47%, oleic acid (20.89%, and linoleic acid (4.31% were prominent. The mineral profiling was carried out by inductively coupled plasma optical emission spectrometer (ICP-OES, and it was found to contain a number of important dietary mineral elements. The harsh climatic conditions, difficult terrain, and logistic constraints at high altitude regions of Indian trans-Himalayan cold desert lead to the scarcity of fresh fruits and vegetables. Therefore, the source of multiple vitamins, essential amino acids, fatty acids, and dietary minerals from the phytococktail would provide great health benefit

    Full Text Available Phytoplankton drives primary productivity in marine pelagic systems. This is also true for the oligotrophic waters in coral reefs, where natural and anthropogenic sources of nutrients can alter pelagic trophic webs. In this study, microphytoplankton assemblages were characterized for the first time in relation to expected coral spawning dates in the Caribbean. A hierarchical experimental design was used to examine these assemblages in Los Roques archipelago, Venezuela, at various temporal and spatial scales for spawning events in both 2007 and 2008. At four reefs, superficial water samples were taken daily for 9 days after the full moon of August, including days before, during and after the expected days of coral spawning. Microphytoplankton assemblages comprised 100 microalgae taxa at up to 50 cells per mL (mean ± 8 SD and showed temporal and spatial variations related to the coral spawning only in 2007. However, chlorophyll a concentrations increased during and after the spawning events in both years, and this was better matched with analyses of higher taxonomical groups (diatoms, cyanophytes and dinoflagellates, that also varied in relation to spawning times in 2007 and 2008, but asynchronously among reefs. Heterotrophic and mixotrophic dinoflagellates increased in abundance, correlating with a decrease of the diatom Cerataulina pelagica and an increase of the diatom Rhizosolenia imbricata. These variations occurred during and after the coral spawning event for some reefs in 2007. For the first time, a fresh-water cyanobacteria species of Anabaena was ephemerally found (only 3 days in the archipelago, at reefs closest to human settlements. Variability among reefs in relation to spawning times indicated that reef-specific processes such as water residence time, re-mineralization rates, and benthic-pelagic coupling can be relevant to the observed patterns. These results suggest an important role of microheterotrophic grazers in re

    Among the many factors that potentially influence the rate at which nitrogen (N) becomes available to plants in terrestrial ecosystems are the identity and diversity of species composition, frequency of disturbance or stand turnover, and time. Replicated suites of investigator-designed communities afforded an opportunity to examine the effects of those factors on net N mineralization over a 12-year period. The communities consisted of large-stature perennial plants, comprising three tree species (Hyeronima alchorneoides, Cedrela odorata, and Cordia alliodora), a palm (Euterpe oleracea), and a large, perennial herb (Heliconia imbricata). Trees were grown in monoculture and in combination with the other two life-forms; tree monocultures were subjected to rotations of one or four years, or like the three-life-form systems, left uncut. The work was conducted on fertile soil in the humid lowlands of Costa Rica, a site with few abiotic constraints to plant growth. Rates of net N mineralization and nitrification were high, typically in the range of 0.2-0.8 microg x g(1) x d(-1), with net nitrification slightly higher than net mineralization, indicating preferential uptake of ammonium (NH4+) by plants and microbes. Net rates of N mineralization were about 30% lower in stands of one of the three tree species, Hyeronima, than in stands of the other two. Contrary to expectations, short-rotation management (one or four years) resulted in higher net rates of N mineralization than in uncut stands, whether the latter were composed of a single tree species or a combination of life-forms. Neither additional species richness nor replenishment of leached N augmented mineralization rates. The net rate at which N was supplied tended to be lowest in stands where demand for N was highest. Careful choice of species, coupled with low frequency of disturbance, can lead to maintenance of N within biomass and steady rates of within-system circulation, whereas pulses, whether caused by cutting

    2008-12-01

    We examined soil water use patterns of four model plant associations established in the North Caribbean lowlands of Costa Rica by comparing the stable hydrogen isotope composition, deltaD, in xylem sap and in soil water at different depths, under rainy and dry conditions. Four 5-year-old model plant associations composed of 2 tree species (Hyeronima alchorneoides and Cedrela odorata) having different architecture and phenology were studied. Average tree height was 8.9 and 7.6 m, respectively. Each tree species was grown in monoculture and in polyculture with 2 perennial monocotyledons (Euterpe oleracea and Heliconia imbricata). Maximum rooting depth at the time of 6D determination was approximately 2 m for almost all species. Most roots of all species were concentrated in the upper soil layers. Stomatal conductance to water vapor (gS) was higher in the deciduous C. odorata than in the evergreen H. alchorneoides; within each species, g, did not differ when the trees were grown in mono or in polyculture. During the rainy season, gradients in soil water 6D were not observed. Average rainy season xylem sap deltaD did not differ among members of the plant combinations tested (-30% per thousand), and was more similar to deltaD values of shallow soil water. Under dry conditions, volumetric soil water content declined from 50 to approximately 35%, and modest gradients in soil water deltaD were observed. Xylem sap deltaD obtained during dry conditions was significantly lower than rainy season values. Xylem sap deltaD of plants growing in the four associations varied between -9 and -22% per hundred, indicating that shallow water was predominantly absorbed during the dry period too. Differences in xylem sap deltaD of trees and monocots were also detected, but no significant patterns emerged. The results suggest that: (a) the plant associations examined extracted water predominantly from shallow soil layers (<1 m), (b) the natural isotopic variation in soil and plant water at

We aimed to investigate an elderly population of Swedish stroke patients for evidence of sustained peripheral inflammation 18 months post-stroke and to identify if inflammation is associated with post-stroke depression at 18 months post-stroke.Methods: The Barthel Index was used to measure the level of impairment in activities of daily living at 3 days post-stroke. Serum concentrations of inflammation markers, ie, C-reactive protein and white cell count, were measured in 149 stroke patients (mean age 81 ± 5.33 years, 35% male at 18 months post-stroke, and a comparison was made with an age-matched sample of elderly Swedish individuals who had not suffered a stroke. At the same visit, clinical depression was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised criteria. Severity of depression was assessed using the Montgomery-Asberg Depression Rating Scale (MADRS.Results: Mean C-reactive protein and white cell count levels in stroke patients were significantly elevated at 18 months post-stroke compared with population probands. Disability scores were associated with MADRS depression scores, but C-reactive protein and white cell count were not.Conclusion: We found evidence for a sustained peripheral inflammatory response at 18 months

  2. cAMP and in vivo hypoxia induce tob, ifr1, and fos expression in erythroid cells of the chick embryo.

    During avian embryonic development, terminal erythroid differentiation occurs in the circulation. Some of the key events, such as the induction of erythroid 2,3-bisphosphoglycerate (2,3-BPG), carbonic anhydrase (CAII), and pyrimidine 5'-nucleotidase (P5N) synthesis are oxygen dependent (Baumann R, Haller EA, Schöning U, and Weber M, Dev Biol 116: 548-551, 1986; Dragon S and Baumann R, Am J Physiol Regulatory Integrative Comp Physiol 280: R870-R878, 2001; Dragon S, Carey C, Martin K, and Baumann R, J Exp Biol 202: 2787-2795, 1999; Dragon S, Glombitza S, Götz R, and Baumann R, Am J Physiol Regulatory Integrative Comp Physiol 271: R982-R989, 1996; Dragon S, Hille R, Götz R, and Baumann R, Blood 91: 3052-3058, 1998; Million D, Zillner P, and Baumann R, Am J Physiol Regulatory Integrative Comp Physiol 261: R1188-R1196, 1991) in an indirect way: hypoxia stimulates the release of norepinephrine (NE)/adenosine into the circulation (Dragon et al., J Exp Biol 202: 2787-2795, 1999; Dragon et al., Am J Physiol Regulatory Integrative Comp Physiol 271: R982-R989, 1996). This leads via erythroid beta-adrenergic/adenosine A(2) receptor activation to a cAMP signal inducing several proteins in a transcription-dependent manner (Dragon et al., Am J Physiol Regulatory Integrative Comp Physiol 271: R982-R989, 1996; Dragon et al., Blood 91: 3052-3058, 1998; Glombitza S, Dragon S, Berghammer M, Pannermayr M, and Baumann R, Am J Physiol Regulatory Integrative Comp Physiol 271: R973-R981, 1996). To understand how the cAMP-dependent processes are initiated, we screened an erythroid cDNA library for cAMP-regulated genes. We detected three genes that were strongly upregulated (>5-fold) by cAMP in definitive and primitive red blood cells. They are homologous to the mammalian Tob, Ifr1, and Fos proteins. In addition, the genes are induced in the intact embryo during short-term hypoxia. Because the genes are regulators of proliferation and differentiation in other cell types, we suggest that c

  3. Teaching science for conceptual change: Toward a proposed taxonomy of diagnostic teaching strategies to gauge students' personal science conceptions

    Science.gov (United States)

    Shope, Richard Edwin, III

    Science instruction aims to ensure that students properly construct scientific knowledge so that each individual may play a role as a science literate citizen or as part of the science workforce (National Research Council, 1996, 2000). Students enter the classroom with a wide range of personal conceptions regarding science phenomena, often at variance with prevailing scientific views (Duschl, Hamilton, & Grandy, 1992; Hewson, 1992). The extensive misconceptions research literature emphasizes the importance of diagnosing students' initial understandings in order to gauge the accuracy and depth of what each student knows prior to instruction and then to use that information to adapt the teaching to address student needs. (Ausubel, 1968; Carey, 2000; Driver et al., 1985; Karplus & Thier, 1967; Mintzes, Wandersee, & Novak, 1998; Osborne & Freyberg, 1985; Project 2061, 1993; Strike & Posner, 1982, 1992; Vygotsky, 1934/1987). To gain such insight, teachers diagnose not only the content of the students' personal conceptions but also the thinking processes that produced them (Strike and Posner, 1992). Indeed, when teachers design opportunities for students to express their understanding, there is strong evidence that such diagnostic assessment also enhances science teaching and learning (Black & William, 1998). The functional knowledge of effective science teaching practice resides in the professional practitioners at the front lines---the science teachers in the classroom. Nevertheless, how teachers actually engage in the practice of diagnosis is not well documented. To help fill this gap, the researcher conducted a study of 16 sixth grade science classrooms in four Los Angeles area middle schools. Diagnostic teaching strategies were observed in action and then followed up by interviews with each teacher. Results showed that teachers use strategies that vary by the complexity of active student involvement, including pretests, strategic questions, interactive discussion

[Methods] 200 normal 6-month-old infants were assigned to early education group (100 subjects) and the control group (100 subjects). All children of the two groups were assessed by Careys Children Temperamental Questionnaires. [Results] There was significant difference of the temperamental types between the two groups (all P<0. 05). The factor of mothers with low degree and low family income had negative effect on the temperament of infants. The early education could decrease the number of infants of difficult-to-raise type. [Conclusion] Early education has positive effect on the children's temperament,and promotes the development of infants.

  5. Changing theory, changing role of Coriolis effect - The East-West asymmetry of the Wadati-Benioff seismic zones

    It is a long history the tale of the recognized asymmetries of the Earth. In 1600 William Gilbert (1544-1603) published De Magnete in which the North and South geomagnetic pole are described. In 1620 Francis Bacon (1561-1628) in the XXVIIth aphorism of the Novum Organum (second part) describes the southern tips of the continents, and many other asymmetries were later described. In 1975 Samuel Warren Carey (1911-2002) stated: Neither north and south, nor east and west are tectonically equivalent. A non exhaustive list of asymmetries of the Earth is: The magnetic polarity; The land-hemisphere and the water-hemisphere; Southern tips of the continents; Larger extension of expanding mid-oceanic ridges on the southern hemisphere; South-eastward trend of younger ages in the long Pacific seafloor volcanic chains; A larger width of the seafloor isochrones bands on the Nazca region; A pear-shaped Earth; etc. It is a few decades that the different slopes of the Wadati-Benioff zones oriented towards the east and west has been enclosed in the list. Under the Americas they have angles of about 30 degrees, while under the Pacific east coasts (Asia, Japan) the angles are steeper (Luyendyk, 1970; Isacks & Barazangi, 1977; and many others). The cause of this difference has been identified in the tidal drag that would cause a global shift of the lithosphere towards west - the so called westward drift (Bostrom, 1971; Stevenson & Turner, 1977; among others). This solution has been many times criticized on the basis of the irrelevance of the tidal forces with respect to viscous friction (Jordan, 1974; Ranalli, 2000; Caputo & Caputo, 2012). Moreover, a simplistic evaluation of the regime of the convective motion in the mantle and of the order of magnitude of the involved forces (viscous, buoyancy, inertial) hastily judges as negligible the role of the Coriolis effect in producing the observed slope differences of the Wadati-Benioff regions. Instead, it is possible to show that changing

    The purpose of this research is to develop a cooperative learning model based on local wisdom (PKBKL) of Bali (Tri Pramana’s concept), for physical education, sport, and health learning in VII grade of Junior High School in Singaraja-Buleleng Bali. This research is the development research of the development design chosen refers to the development proposed by Dick and Carey. The development of model and learning devices was conducted through four stages, namely: (1) identification and needs analysis stage (2) the development of design and draft of PKBKL and RPP models, (3) testing stage (expert review, try out, and implementation). Small group try out was conducted on VII-3 grade of Undiksha Laboratory Junior High School in the academic year 2013/2014, large group try out was conducted on VIIb of Santo Paulus Junior High School Singaraja in the academic year 2014/2015, and the implementation of the model was conducted on three (3) schools namely SMPN 2 Singaraja, SMPN 3 Singaraja, and Undiksha laboratory Junior High School in the academic year 2014/2015. Data were collected using documentation, testing, non-testing, questionnaire, and observation. The data were analyzed descriptively. The findings of this research indicate that: (1) PKBKL model has met the criteria of the operation of a learning model namely: syntax, social system, principles of reaction, support system, as well as instructional and nurturing effects, (2) PKBKL model is a valid, practical, and effective model, (3) the practicality of the learning devices (RPP), is at the high category. Based on the research results, there are two things recommended: (1) in order that learning stages (syntax) of PKBKL model can be performed well, then teachers need to have an understanding of the cooperative learning model of Student Team Achievement Division (STAD) type and the concepts of scientifically approach well, (2) PKBKL model can be performed well on physical education, sport and health learning, if the

    My name is Siobhan McDonald. I am a visual artist living and working in Dublin. My studio is based in The School of Science at University College Dublin where I was Artist in Residence 2013-2015. A fascination with time and the changeable nature of landmass has led to ongoing conversations with scientists and research institutions across the interweaving disciplines of botany, biology and geology. I am developing a body of work following a recent research trip to the North Pole where I studied the disappearing landscape of the Arctic. Prompted by my experience of the Arctic shelf receding, this new work addresses issues of the instability of the earth's materiality. The work is grounded in an investigation of material processes, exploring the dynamic forces that transform matter and energy. This project combines art and science in a fascinating exploration of one of the Earth's last relatively untouched wilderness areas - the High Arctic to bring audiences on journeys to both real and artistically re-imagined Arctic spaces. CRYSTALLINE'S pivotal process is collaboration: with The European Space Agency; curator Helen Carey; palaeontologist Prof. Jenny McElwain, UCD; and with composer Irene Buckley. CRYSTALLINE explores our desire to make corporeal contact with geological phenomena in Polar Regions. From January 2016, in my collaboration with Jenny McElwain, I will focus on the study of plants and atmospheres from the Arctic regions as far back as 400 million years ago, to explore the essential 'nature' that, invisible to the eye, acts as imaginary portholes into other times. This work will be informed by my arctic tracings of sounds and images recorded in the glaciers of this disappearing frozen landscape. In doing so, the urgencies around the tipping of natural balances in this fragile region will be revealed. The final work will emerge from my forthcoming residency at the ESA in spring 2016. Here I will conduct a series of workshops in ESA Madrid to work with

In the investigation area, the base of the sediments that belongs to Neogene, consist of the volcanics which are formed with basalts, andesites and tuff. Neogene begins unconformity with basal conglomerate which are formed with basalt and tuff gravels. The measurable thickness of the Neogene sediments is approximately 200meters in total. First fossiliferius level which consist of Lymnocardium (Euxinicardium) nobile Sabba has showed similarities with the Pontian (Late Miocene) fauna of the Eastern Paratethys.

  14. ‘I can touch him now’: Harry Potter as a Gothic Narrative of Trauma and Homoerotic Sexual Abuse

    Directory of Open Access Journals (Sweden)

    Full Text Available In this article I argue that the Harry Potter novels constitute a Gothic narrative about homoerotic child abuse. The various confrontations between Harry and the Dark Lord are interpreted as representing the unavoidable encounter with what Ruth Bienstock Anolik has defined as ‘the sexual Other’ infiltrating the Self in Gothic texts. Specifically, I examine the re-enactment of trauma in the narrative as a typical trope of the Gothic. Harry’s progressive acquisition of knowledge on his adversary is therefore interpreted as a metaphor for the gradual re-assertion of repressed traumatic memories on consciousness.Keywords: Harry Potter, trauma, repression, Gothic, abuseThe critical readings on J. K. Rowling’s Harry Potter novels hitherto published have mainly focused on the commercially-successful and worldwide consumerist phenomenon of the series and have specifically considered it as belonging to the literary genre of children literature (Carey 159; Rangwala 140; Nafici 209; Nikolajeva 240. We could, however, also inscribe the series into the Gothic genre. This is due to the use of many figures (such as the monster, locations (such as the castle, and tropes (such as the depiction of the story’s villain as a sexual threat or the theme of the return of the past that are typical of the Gothic genre. The novels begin with the murders of Lily and James Potter and the attempt on the life of Harry (Hook 91 and are then permeated by the “themes of evil, darkness, destruction and murder” (Patrick and Patrick 221. As some critics have noted, there are “numerous and horrendous instances of violence” (Taub and Servaty-Seib 22 throughout the series and death is one of the dominant themes of the narrative, which “moves from wonder, innocence, and comedy to fear, experience, and tragedy” (Behr 263. Secondly, many of the scenes of the seven novels are set in environments which are typically Gothic, as the following examples illustrate: the

    In 1955, Carey first suggested a rotational opening of the Arctic Ocean based on his theories concerning oroclinal bending. It was only with the plate tectonic revolution in the next decade that there were a number of seminal abstracts and papers concerning the tectonic evolution of the Canada Basin. Grantz in 1966, Hamilton in 1967 and Tailleur in 1969 formulated the idea that the Canada Basin may have opened about a pivot point in the Mackenzie Delta. In 1968, Karasik first published his revolutionary idea that aeromagnetic anomalies collected over the Gakkel Ridge in the Eurasian Basin suggested that seafloor spreading during the Tertiary accounted for most of the oceanic crust between the Lomonosov Ridge and the Barents and Kara shelves. From the results of the 1979 Lomonosov Ridge experiment by Forsyth and Mair, it was established that the deep crustal velocities of the Lomonosov Ridge are remarkably similar to those of the Kara Sea shelf at 82°N, making it a continental sliver that rifted off the Barents and Kara Sea shelves. Consequently, the Arctic Ocean can be divided into a mostly Tertiary to present Eurasian Basin, and the older Mesozoic Amerasian Basin. Even with additional data from the Amerasian Basin including extensive airborne, ship-based, and satellite magnetics and gravity, the tectonic evolution of the Canada and Makarov components of the Amerasian Basin are still controversial. While the final phase of opening of the Amerasian Basin may have been rotational about a pivot point near or south of the Mackenzie Delta, the earlier phases and even the directions of the initial basin formation are still in doubt. Vogt and others first suggested a possible hotspot origin for the Alpha and Mendeleev Ridges and related them to the Iceland hotspot. Age versus depth and heat flow versus depth give a tentative age for the Amerasian Basin of latest Jurassic to early Cretaceous with seafloor spreading ending prior to the beginning of the Cretaceous Normal

    At the bottom of the world's oceans lies layer after layer of ash deposited from past volcanic eruptions. Correct interpretation of these layers can provide important constraints on the duration and frequency of volcanism, but requires a full understanding of the complex multi-phase settling and deposition process. Analogue experiments of tephra settling through a tank of water demonstrate that small ash particles can either settle individually, or collectively as a gravitationally unstable ash-laden plume. These plumes are generated when the concentration of particles exceeds a certain threshold such that the density of the tephra-water mixture is sufficiently large relative to the underlying particle-free water for a gravitational Rayleigh-Taylor instability to develop. These ash-laden plumes are observed to descend as a vertical density current at a velocity much greater than that of single particles, which has important implications for the emplacement of tephra deposits on the seabed. To extend the results of laboratory experiments to large scales and explore the conditions under which vertical density currents may form and persist, we have developed a multi-phase extension to Fluidity, a combined finite element / control volume CFD code that uses adaptive unstructured meshes. As a model validation, we present two- and three-dimensional simulations of tephra plume formation in a water tank that replicate laboratory experiments (Carey, 1997, doi:10.1130/0091-7613(1997)0252.3.CO;2). An inflow boundary condition at the top of the domain allows particles to flux in at a constant rate of 0.472 gm-2s-1, forming a near-surface layer of tephra particles, which initially settle individually at the predicted Stokes velocity of 1.7 mms-1. As more tephra enters the water and the particle concentration increases, the layer eventually becomes unstable and plumes begin to form, descending with velocities more than ten times greater than those of individual particles.

    In reduced coordinates, a one-dimensional finite strain consolidation equation for saturated soils is derived with threshold gradient. The new equation shows that threshold gradient and variation of permeability coefficient with void ratio should be considered. Using the two empirical relations proposed by Mesri, a new governing equation is obtained. Then three examples are analyzed by applying the partial differential finite element software FlexPDE. The results show that excess pore water pressure slightly increases at the beginning of consolidation progress and then dissipates. This phenomenon is similar to the Mandel-Cryer effect. It will be more significant if threshold gradient is greater or location of soil is deeper. Even though the maximum excess pore water pressure increases when threshold gradient increases, the increment is very small. It is too difficult for us to observe the tiny increments in laboratory and practical engineerings. Therefore, there is no need to consider threshold gradient in vast majority of actual projects. In other words, classical Carey's law is applicable. This research shows that it is very important to consider threshold gradient, geometric nonlinearity and material nonlinearity in studying the Mandel-Cryer effect so as to further understand the consolidation properties of saturated soils.%在固相物质坐标下推导出了考虑起始比降的饱和土体一维大应变固结控制方程.从新方程可以看出,要综合考虑土体固结过程中的渗流非线性,要同时考虑起始比降和渗透系数随孔隙比的变化.采用Mesri提出的两个经验关系式进一步推导出了新的控制方程.借助偏微分有限元软件FlexPDE对3个算例进行了分析.分析结果表明,土体固结开始阶段超静孔压先略微增大,然后减小,类似于Mandel-Cryer效应.起始比降越大,土层越深,该现象越显著.虽然超静孔压最大值随起始比降的增大而增大,但增量很小.如此微小的

    diffusion of CO2 into the cement matrix and carbonation of the cement to CaCO3. The cement interface did not appear to have been significantly eroded. The experiment was used to calibrate numerical models for corrosion rates and for cement carbonation. These results were applied to interpret samples recovered from a CO2-enhanced oil recovery field (SACROC in West Texas; Carey et al. 2007, Int J. Greenhouse Gas Control, 1: 75-85). The results suggest that CO2-brine flux must have been limited along the cement-casing interface because the casing showed very little corrosion. They also suggest that CO2 penetration along the cement-formation interface was limited in volume because the depth of carbonation at SACROC was limited. These microscale models suggest that cement-casing flow has the potential to be self-limiting due to precipitation of CO2 and that standard logging measurements of casing integrity can be used to assess whether significant flow of CO2-brine has occurred at the casing interface.

    previous work with poorer resolution indicated no polarization. Most importantly they recognized that the implied radial field "suggests that the magnetic field has been carried out with the expansion of the supernova envelope, and...[they] observe[d] polarized radiation associated with a component which has been stretched out in the radial direction during the expansion of the shell." This landmark paper led the way for later polarimetric studies of both galactic and extragalactic radio sources. Observations two decades later with the VLA (the world's most powerful, synthesis radio telescope with a quarter million pixels to each one of Connie's), substantiated most or all of his early conclusions, and was a tribute to his pioneering effort. The NRL group was later involved in discoveries about the variability of interstellar water and SiO masers, the structure of molecular clouds and star forming regions, the development of techniques for precision time transfer, remote sensing of the ocean and atmosphere, and much else, but in the aforementioned radio astronomy work, Connie Mayer had no peer. A colleague remarked, "Connie was among the last of the scientist-engineers who built their own equipment, performed their own experiments, and also interpreted the results into paradigm shifting science." Connie was a rare and noble example of natural modesty, becoming uncomfortable if anyone praised him. After his death, his wife found many awards that he had received but never framed nor told her about. He joked that he did not want a formal funeral "with a lot of people getting up and mouthing off about me." He received full military honor services at Arlington National Cemetery, but was cremated as per his wishes. He is survived by Carey Whitehead Mayer, his wife of fifty-six years, and their daughter, Carolyn Elizabeth Mayer. Their son, John, died in 1978.

    Objective To analyze the differences among the intellectual development and temperament behavior of premature infants and those of normal full-term infants in their infant period, so as to explore the law to promote the health growth of the intelligence and temperament behavioral of premature infants. Methods 68 cases of premature infants appropriate for gestational age and 102 cases of normal full-term infants were randomly selected for the establishment of cohort as the research subjects. The data of their developmental screening test (DST) at 12 months old were reviewed; and they respectively received Gesell infant intellectual development check at 18, 24, 30 months old, and their parents also received Carey infant temperament questionnaire (RITQ), and received Achenbach infant behavior checklist at 30 months old of the infants. A longitudinal analysis was performed on the differences among the results of the intellectual developments in 5 functional areas(applicability, large motion, fine motion, language, personal-social competence) with the increase in ages and the results of temperament checklist and dimension. The Student's t test, variance analysis, SNK-q test was used as statistical methods, and χ2 analysis was used for the comparison among the constituent ratios of segmental information. Results Compared with the full-term infants, the developmental quotient(DQ) and mental index(MI) at 12-month-old, as well as the DQ of five major functional areas at 18-month-old, 24-month-old and 30-month-old of the premature infants were lower; for the premature infants with corrected gestational age, their adaptability, large motion, fine motor and language at 18-month-old was statistically significant (P<0.05); their adaptability and language at 24-month-old were weaker than those of the full-term infants (P<0.05);and their language and personal social ability were weaker than those of the full-term infants (P<0.05). On aspect of temperament, each temperament
