    2001-01-01

    For the present study seven patients presenting periodontal disease were selected in a way that they required the performance of gingivectomy procedure in the region of premolars in both sides, being this in the upper or lower region. After the surgical procedure one side was submitted to low intensity laser radiation, wavelength 685 nm, power 50 mW and fluency of 4J/cm 2 , contact mode. The other side was used as a control, not receiving any laser irradiation. Healing process for both sides, was clinically and biometrically evaluated and compared using photographs for the periods: pre-operative, immediate post-operative, 3, 7,14,21, 28 and 35 days. The analysis was performed by 3 specialists in Periodontology considering aspects of healing. Results were submitted to statistical analysis. Biometrical evaluation showed improvement of healing for the period of 21 and 28 days in the lased group. Clinical evaluation showed better reparation mainly after the third day for the active group. Laser group was considered to present an improved healing when compared to the control group. (author)

    For this study 20 patients with periodontal disease were selected. The treatment required for all of then was the gingivectomy, a ressective periodontal surgery. This technique consists of removing the whole excess of gingival tissue with the intent of reestablishing the anatomy and the correct function. The gingival area was submitted to 2 different wavelengths and then histologically analysed to search for alterations, mainly concerning mast cells behavior, a blood cell responsible, among other things, for blood vases enlargement. During the surgical procedure each gingival area was submitted to infrared low intensity laser (λ = 785 nm) or to red laser (λ = 688 nm), both with 50 mW of power and fluence of 8 J/cm 2 . A third area was analysed, the control area, in which no laser treatment was employed. The samples were fixated in formol, cut and stained by hematoxyline eosine and toluidine blue. Based on the result we can conclude: the 2 wavelengths used in this study led to the reduction in the number of mast cells present in the tissue as well as to the increase on the degranulation of the remaining mast cells, considered statistically significant taken the degranulation index and; there was no significant difference caused by the action of the two laser wavelengths λ=785 nm and λ=688 nm -50 mW of power and fluence of 8 J/cm 2 -, over the degranulation of the mast cells; the length and width of the randomly chosen blood vases were not statistically different among the analysed groups.

    2017-08-01

    Full Text Available Focusing on Joyce’s use of Aristotle’s De Anima, and on Aquinas’s response to Aristotle, this essay takes, as its starting point, the recourse to two areas of enquiry in recent work on modernism: animal studies and phenomenology. In this essay we examine the intersection within Ulysses of the concept of the soul in Aristotle and Aquinas, show how this relates to questions of animality, and open the way to asking what implication the theological reflection on the soul at the centre of Ulysses might have for a process of uncovering theological contents in the concept of “life” in modernist studies more generally.

    Polyethylene glycol (PEG) as a green solvent was employed to extract polysaccharide. The optimal conditions for PEG-based ultrasonic extraction of Dendrobium nobile Lindl. polysaccharide (JCP) were determined by response surface methodology. Under the optimal conditions: extraction temperature of 58.5°C; ultrasound power of 193W, and the concentration of polyethylene glycol-200 (PEG-200) solution of 45%, the highest JCP yield was obtained as 15.23±0.57%, which was close to the predicted yield, 15.57%. UV and FT-IR analysis revealed the general characteristic absorption peaks of both JCP with water extraction (JCP w ) and PEG-200 solvent extraction (JCP p ). Thermal analysis of both JCPs was performed with Thermal Gravimetric Analyzer (TGA) and Differential Scanning Calorimeter (DSC). Antioxidant activities of two polysaccharides were also compared and no significant difference in vitro was obtained. Copyright © 2016 Elsevier B.V. All rights reserved.

    Today considerable number of drugs are produced from plants. Several plants with antibacterial and healing applications are used in medicine such as Roman chamomile (Chamaemelum nobile L.). Wound infection is one of the most prevalent infections among infectious diseases around the world. Due to appearance of drug resistance, researchers are now paying attention to medicinal plants. Therefore, this study was designed to investigate the antimicrobial and wound healing properties of C. nobile against Pseudomonas aeruginosa using in vivo conditions. Ethanolic extract of C. nobile was provided using standard method. The 5% C. nobile ointment was prepared by dissolving lyophilized extract in eucerin. Forty five male rats were obtained from Ilam university. After anesthetization and wound creation, wounds were infected by P. aeruginosa. The rats were divided into three groups, group I was treated with C. nobile ointment, group II was treated with tetracycline ointment and the third group was treated with base gel as control group. Antibacterial and wound healing activities of C. nobile ointment were more than tetracycline ointment significantly. Our results indicated that extract of C. nobile had effective antibacterial activity and accelerated the progression of wound healing. Our study indicated that antibacterial and wound healing activities of C. nobile ointment were notable. C. nobile therapy in combination with antibiotics can also be useful because medicinal plants contents operate in synergy with antibiotics. These results revealed the value of plant extracts to control antibiotic resistant bacteria in wound infections.

    Full Text Available This study, conducted at Jardinocultura area of Faculdade de Ciências Agrárias of UFGD during the period from September of 2010 to August of 2011, had as aim evaluate the cultivation and flowering of Dendrobium nobile Lindl., under five levels of luminosity (83, 104, 115, 154 e 237 μmol m-2 s-1 . During 12 months the plants were irrigated and fertilized with NPK 10-10-10 and after this period they were evaluated for the number, length and diameter of pseudobulbs, being calculated the increments in relation to initial data. At flowering time it was counted the total buds, reproductive buds, vegetative buds and undifferentiated buds and registered the anthesis at each light intensity. The experimental was arranged at completely randomized design with five treatments and seven replicates with two plants and the averages were compared by Tukey test at 5% probability. All the lighting conditions were favorable to the D. nobile cultivation, being registered increases of 36,7%, 16,0% e 16,2% in the number, diameter and length of pseudobulbs, respectively. The largest number of reproductive buds was observed at 104 μmol m-2 s-1. D. nobile can be cultivated in the light conditions varying between 83 and 237 μmol m-2 s-1, recommending the luminosity of 104 μmol m-2 s-1 to promote their flowering.

    Little is still known about the microbiome resulting from the process of mummification of the human gut. In the present study, the gut microbiota, genes associated with metabolism, and putative resistome of Inca and Italian nobility mummies were characterized by using high-throughput sequencing. The Italian nobility mummies exhibited a higher bacterial diversity as compared to the Inca mummies when using 16S ribosomal (rRNA) gene amplicon sequencing, but both groups showed bacterial and fungal taxa when using shotgun metagenomic sequencing that may resemble both the thanatomicrobiome and extant human gut microbiomes. Identification of sequences associated with plants, animals, and carbohydrate-active enzymes (CAZymes) may provide further insights into the dietary habits of Inca and Italian nobility mummies. Putative antibiotic-resistance genes in the Inca and Italian nobility mummies support a human gut resistome prior to the antibiotic therapy era. The higher proportion of putative antibiotic-resistance genes in the Inca compared to Italian nobility mummies may support the hypotheses that a greater exposure to the environment may result in a greater acquisition of antibiotic-resistance genes. The present study adds knowledge of the microbiome resulting from the process of mummification of the human gut, insights of ancient dietary habits, and the preserved putative human gut resistome prior the antibiotic therapy era.

    Dendrobium nobile is one of the fundamental herbs in traditional Chinese medicine. Sesquiterpene alkaloids are the main active components in this plant. Due to weak ultraviolet absorption and low content in D. nobile, these sesquiterpene alkaloids have not been extensively studied using chromatographic methods. Herein, tandem mass spectrometry combined with liquid chromatography separation provides a tool for the identification and characterization of the alkaloids from D. nobile. A total of nine sesquiterpene alkaloids were characterized by ultrahigh-performance liquid chromatography tandem mass spectrometry. These alkaloids can be classified into two subgroups that are represented by dendrobine and nobilonine. Tandem mass spectrometric studies revealed the fragmentation pathways of these two subgroup alkaloids that were used for the identification and characterization of other alkaloids in D. nobile. Characterization of these alkaloids using accurate mass and diagnostic fragments provided a reliable methodology for the analysis of D. nobile by ultrahigh-performance liquid chromatography tandem mass spectrometry. The limit of detection was defined as the signal-to-noise ratio equal to 3 : 1. Limits of detection of dendrobine and nobilonine were less than 30 ng/mL. The developed method was applied for the analysis of various Dendrobium species and related dietary supplements. Alkaloids were identified from D. nobile, but not detected from commercial samples including 13 other Dendrobium species and the 7 dietary supplements. Georg Thieme Verlag KG Stuttgart · New York.

  15. Evaluation of Metal Toxicity in Streams Affected by Abandoned Mine Lands, Upper Animas River Watershed, Colorado

    Acid drainage from abandoned mines and from naturally-acidic rocks and soil in the upper Animas River watershed of Colorado generates elevated concentrations of acidity and dissolved metals in stream waters and deposition of metal-contaminated particulates in streambed sediments, resulting in both toxicity and habitat degradation for stream biota. High concentrations of iron (Fe), aluminum (Al), zinc (Zn), copper (Cu), cadmium (Cd), and lead (Pb) occur in acid streams draining headwaters of the upper Animas River watershed, and high concentrations of some metals, especially Zn, persist in circumneutral reaches of the Animas River and Mineral Creek, downstream of mixing zones of acid tributaries. Seasonal variation of metal concentrations is reflected in variation in toxicity of stream water. Loadings of dissolved metals to the upper Animas River and tributaries are greatest during summer, during periods of high stream discharge from snowmelt and monsoonal rains, but adverse effects on stream biota may be greater during winter low-flow periods, when stream flows are dominated by inputs of groundwater and contain greatest concentrations of dissolved metals. Fine stream-bed sediments of the upper Animas River watershed also contain elevated concentrations of potentially toxic metals. Greatest sediment metal concentrations occur in the Animas River upstream from Silverton, where there are extensive deposits of mine and mill tailings, and in mixing zones in the Animas River and lower Mineral Creek, where precipitates of Fe and Al oxides also contain high concentrations of other metals. This report summarizes the findings of a series of toxicity studies in streams of the upper Animas River watershed, conducted on-site and in the laboratory between 1998 and 2000. The objectives of these studies were: (1) to determine the relative toxicity of stream water and fine stream-bed sediments to fish and invertebrates; (2) to determine the seasonal range of toxicity in stream

    Chamaemelum nobile ( Asteraceae ) commonly known as 'Roman chamomile' is a medicinal plant used for numerous diseases in traditional medicine, although its anticancer activity is unknown. The present study was carried out to investigate the anticancer as well as apoptotic activity of ethyl acetate fraction of C. nobile on different cancerous cell lines. The cells were treated with varying concentrations (0.001- 0.25 mg/mL) of this fraction for 24, 48 and 72 h. Apoptosis induced in MCF-7 cells following treatment with ethyl acetate fraction was measured using Annexin V/PI, flowcytometry and western blotting analysis. The results showed that C. nobile ethyl acetate fraction revealed relatively high antiproliferative activity on MCF-7 cells; however, it caused minimal growth inhibitory response in normal cells. The involvement of apoptosis as a major cause of the fraction-induced cell death was confirmed by annexin-V/PI assay. In addition, ethyl acetate fraction triggered the mitochondrial apoptotic pathway by decreasing the Bcl-2 as well as increasing of Bax protein expressions and subsequently increasing Bax/Bcl-2 ratio. Furthermore, decreased proliferation of MCF-7 cells in the presence of the fraction was associated with G2/M phase cell cycle arrest. These findings confirm that ethyl acetate fraction of C.nobile may contain a diversity of phytochemicals which suppress the proliferation of MCF-7 cells by inducing apoptosis.

    Chamomile (Chamaemelum nobile) is widely used throughout the world, and has anti-inflammatory, deodorant, bacteriostatic, antimicrobial, carminative, sedative, antiseptic, anti-catarrhal, and spasmolytic properties. Because of the increasing incidence of drug-resistant bacteria, the development of natural antibacterial sources such as medical herbs for the treatment of infectious diseases is necessary. Extracts from different plant parts such as the leaves, flowers, fruit, and bark of Combretum albiflorum, Laurus nobilis , and Sonchus oleraceus were found to possess anti-quorum sensing (QS) activities. In this study, we evaluated the effect of C. nobile against Pseudomonas aeruginosa biofilm formation. The P. aeruginosa samples were isolated from patients with different types of infection, including wound infection, septicemia, and urinary tract infection. The flowers of C. nobile were dried and the extract was removed using a rotary device and then dissolved in dimethyl sulfoxide at pH 7.4. The microdilution method was used to evaluate the minimum inhibitory concentration (MIC) of this extract on P. aeruginosa , and biofilm inhibition was assayed. Eighty percent of the isolated samples (16/20) could form a biofilm, and most of these were isolated from wound infections. The biofilm inhibitory concentration of the C. nobile extract was 6.25-25mg/ml, whereas the MIC was 12.5-50mg/ml. The anti-QS property of C. nobile may play an important role in its antibacterial activity, thus offering an additional strategy in the fight against bacterial infections. However, molecular investigation is required to explore the exact mechanisms of the antibacterial action and functions of this phytocompound.

    Full Text Available The Heroic Era in Polar Exploration is filled with fascinating stories about interesting men, and the Race for the Poles is richly described in hundreds of books. The Heroic Era in Polar Exploration coincided with the conception of film technology and rise of commercial cinema, and many polar explorers saw potential in utilising this new technology as a research tool. As a result there exists a range of films from the Polar Explorations, but since their making and initial screenings they have received little attention. The story of these films is also an interesting one, although it has not yet been written. A few years after the production of the first film cameras, the explorer Carsten Borchgrevink brought one along on his British Antarctic Expedition in 1898. His main sponsor, a newspaper publisher, wanted to make news films, but the cinematograph, the film reel and the filming skills were not sufficiently developed to capture living images from the polar region. Our record of this first attempt at making a polar film is limited to one scene from when the expedition is leaving London.The first explorer to succeed in filming in the Arctic was Anthony Fiala in 1902, and since his breakthrough the cinematograph became standard scientific equipment on all polar expeditions. The Mechanical Era in Polar Exploration came with the aeroplanes, the airships and the telegraph. Roald Amundsen played a major role here; he claimed his idea about using aeroplanes was as important to the polar exploration as Nansen´s use of skies and dogsledges in the heroic era. This article tells the story about explorers with film camera trying to reach the North Pole from Spitzbergen. Wellman, Amundsen, Byrd and Nobile are the main characters. The story of their fantastic expeditions is told by others; this is the story about their films, and how the films from the Arctic developed from just documenting landscape and animal life until they became proper documentary

    Full Text Available The text from Laza Kostic's poem Santa Maria della Salute is everlasting and changeless but its context regarding the meaning and the poet's evaluation can be changed depending on paradigms that regulate the relationships between the author and the readers. Diary of Dreams that was kept in French by Laza Kostić, the facts from his life and work are interesting enough even for the psychoanalytic explications of the hidden levels of the poem's context. This work presents literary and theoretical revelation of Petar Milosavljević in a unique monograph The life of Laza Kostić's poem Santa Maria della Salute (1981 that corresponds to the Jungian deep psychological analysis of Ivan Nastović in the book The Anima of Laza Kostić (2004. On the basis of the external textual facts, Milosavljević's views concerning the role of a woman in Kostić's poem are formulated in the way that the love toward that young girl is consisted of the projection of Kostić's Anima - the young mother whom he lost too early, counterbalance and the addition of the mother whom he found in his own wife. Simultaneously, that girl in his poem, as well as in his life, has a role of the muse that inspires him, and the role of madonna, Beatrice, who will take him to another world where the differences of all times are silent. The fact is that the fairy is not only an object of love but also the centre by which the poet defined his answer to the world with which he was faced in his late years. Milosavljević's view corresponds with Nastović's deep psychological revealation of the poem Santa Maria della Salute. Nastović mentions Hegel's thought that the truth is a whole and that spiritual life is regarded as a dynamic whole that is consisted of the conscious and unconscious part of the character. In regard to the Jung's view 'the unconscious often knows more and better than the consciousness', the unconscious never lies in comparison with the consciousness. The dreams of Laza

    The present study reports green synthesis of silver nanoparticles (AgNPs) at room temperature using aqueous Chamaemelum nobile extract for the first time. The effect of silver nitrate concentration, quantity of the plant extract and the reaction time on particle size was optimized and studied by UV-Vis spectroscopy and dynamic light scattering. The appearance of brownish color with λ max of 422 nm confirmed the formation of AgNPs. Synthesized nanoparticles were further characterized by Fourier transform infrared spectroscopy, x-ray diffraction and transmission electron microscopy. In addition, antimicrobial activity of the AgNPs against Escherichia coli, Salmonella typhimurium, Staphylococcus aureus and Bacillus subtilis was evaluated based on the inhibition zone using the disc-diffusion assay and measurement of minimal inhibition concentration and minimal bactericidal concentration by standard microdilution method. In conclusion, synthesis of nanoparticle with aqueous Chamaemelum nobile extract is simple, rapid, environmentally benign and inexpensive. Moreover, these synthesized nanoparticles exhibit significant antibacterial activity.

    In our previous studies, Dendrobium nobile Lindl. alkaloids (DNLA) has been shown to have glucose-lowering and antihyperlipidaemia effects in diabetic rats, in rats fed with high-fat diets, and in mice challenged with adrenaline. This study aimed to examine the effects of DNLA on the expression of glucose and lipid metabolism genes in livers of mice. Mice were given DNLA at doses of 10-80 mg/kg, po for 8 days, and livers were removed for total RNA and protein isolation to perform real-time RT-PCR and Western blot analysis. Dendrobium nobile Lindl. alkaloids increased PGC1α at mRNA and protein levels and increased glucose metabolism gene Glut2 and FoxO1 expression. DNLA also increased the expression of fatty acid β-oxidation genes Acox1 and Cpt1a. The lipid synthesis regulator Srebp1 (sterol regulatory element-binding protein-1) was decreased, while the lipolysis gene ATGL was increased. Interestingly, DNLA increased the expression of antioxidant gene metallothionein-1 and NADPH quinone oxidoreductase-1 (Nqo1) in livers of mice. Western blot on selected proteins confirmed these changes including the increased expression of GLUT4 and PPARα. DNLA has beneficial effects on liver glucose and lipid metabolism gene expressions, and enhances the Nrf2-antioxidant pathway gene expressions, which could play integrated roles in regulating metabolic disorders. © 2017 Royal Pharmaceutical Society.

    Visible-wavelength and near-infrared image cubes of the Animas River watershed in southwestern Colorado have been acquired by the Jet Propulsion Laboratory's Airborne Visible and InfraRed Imaging Spectrometer (AVIRIS) instrument and processed using the U.S. Geological Survey Tetracorder v3.6a2 implementation. The Tetracorder expert system utilizes a spectral reference library containing more than 400 laboratory and field spectra of end-member minerals, mineral mixtures, vegetation, manmade materials, atmospheric gases, and additional substances to generate maps of mineralogy, vegetation, snow, and other material distributions. Major iron-bearing, clay, mica, carbonate, sulfate, and other minerals were identified, among which are several minerals associated with acid rock drainage, including pyrite, jarosite, alunite, and goethite. Distributions of minerals such as calcite and chlorite indicate a relationship between acid-neutralizing assemblages and stream geochemistry within the watershed. Images denoting material distributions throughout the watershed have been orthorectified against digital terrain models to produce georeferenced image files suitable for inclusion in Geographic Information System databases. Results of this study are of use to land managers, stakeholders, and researchers interested in understanding a number of characteristics of the Animas River watershed.

    2012-01-01

    Full Text Available Vernalization-induced flowering is a cold-relevant adaptation in many species, but little is known about the genetic basis behind in Orchidaceae species. Here, we reported a collection of 15017 expressed sequence tags (ESTs from the vernalized axillary buds of an Orchidaceae species, Dendrobium nobile, which were assembled for 9616 unique gene clusters. Functional enrichment analysis showed that genes in relation to the responses to stresses, especially in the form of low temperatures, and those involving in protein biosynthesis and chromatin assembly were significantly overrepresented during 40 days of vernalization. Additionally, a total of 59 putative flowering-relevant genes were recognized, including those homologous to known key players in vernalization pathways in temperate cereals or Arabidopsis, such as cereal VRN1, FT/VRN3, and Arabidopsis AGL19. Results from this study suggest that the networks regulating vernalization-induced floral transition are conserved, but just in a part, in D. nobile, temperate cereals, and Arabidopsis.

    Dendrobium nobile is an important medicinal orchid having profound importance in traditional herbal drug preparations and pharmacopeias worldwide. Due to various anthropogenic pressures the natural populations of this important orchid species are presently facing threats of extinction. In the present study, genetic and chemical diversity existing amongst 6 natural populations of D. nobile were assessed using molecular markers, and the influence of genetic factors on its phytochemical activity especially antioxidant potential was determined. Molecular fingerprinting of the orchid taxa was performed using ISSR and DAMD markers along with the estimation of total phenolics, flavonoids and alkaloid contents. Antioxidant activity was also measured using DPPH and FRAP assays which cumulatively revealed a significant level of variability across the sampled populations. The representatives from Sikkim in Northeast India revealed higher phytochemical activity whereas those from Mizoram showed lesser activity. Analysis of molecular variance (AMOVA) revealed that variation amongst the populations was significantly higher than within the populations. The data generated by UPGMA and Bayesian analytical models were compared in order to estimate the genetic relationships amongst the D. nobile germplasm sampled from different geographical areas of Northeast India. Interestingly, identical grouping patterns were exhibited by both the approaches. The results of the present study detected a high degree of existing genetic and phytochemical variation amongst the populations in relation to bioclimatic and geographic locations of populations. Our results strongly establish that the cumulative marker approach could be the best suited for assessing the genetic relationships with high accuracy amongst distinct D. nobile accessions.

    Dendrobium nobile Lindl., an epiphytic herb distributed in the Southeast Asia, is used as a tonic and antipyretic herbal medicine in China. In this study, a water-soluble acidic heteropolysaccharide, DNP-W4, containing mannose, glucose, galactose, xylose, rhamnose, and galacturonic acid, in the molar ratios of 1.0:4.9:2.5:0.5:1.0:0.9, was obtained from the stems of Dendrobium nobile Lindl. Using methylation analysis, partial acid hydrolysis, pectolyase treatment, NMR, and ESI-MS, the structure of DNP-W4 was elucidated. The obtained data indicated that DNP-W4 was a complex heteropolysaccharide and possessed a backbone composed of (1→4)-linked β-d-Glcp, (1→6)-linked β-d-Glcp, and (1→6)-linked β-d-Galp, with substitutes at O-4/6 of Glcp residues and O-3 of Galp. The branches of DNP-W4 were composed of terminal Manp, (1→6)-linked β-d-Manp, (1→3)-linked β-d-Glcp, β-d-Glcp, β-d-Galp, (1→4)-linked α-d-GalAp, (1→2)-linked α-L-Rhap, and Xylp. DNP-W4 had little immunological activities, but its derivatives had immuno-stimulating activities to some extent.

    The Gold King Mine spill in August 2015 released 11 million liters of metal-rich mine waste to the Animas River watershed, an area that has been previously exposed to historical mining activity spanning more than a century. Although adsorption onto fluvial sediments was responsible for rapid immobilization of a significant fraction of the spill-associated metals, patterns of longer-term mobility are poorly constrained. Metals associated with river sediments collected downstream of the Gold King Mine in August 2015 exhibited distinct presence and abundance patterns linked to location and mineralogy. Simulating riverbed burial and development of anoxic conditions, sediment microcosm experiments amended with Animas River dissolved organic carbon revealed the release of specific metal pools coupled to microbial Fe- and SO 4 2- -reduction. Results suggest that future sedimentation and burial of riverbed materials may drive longer-term changes in patterns of metal remobilization linked to anaerobic microbial metabolism, potentially driving decreases in downstream water quality. Such patterns emphasize the need for long-term water monitoring efforts in metal-impacted watersheds.

    As one very precious traditional Chinese medicine (TCM), Huoshan Dendrobium has not only high price, but also significant pharmaceutical efficacy. However, different species of Huoshan Dendrobium exhibit considerable difference in pharmaceutical efficacy, so rapid and absolutely non-destructive discrimination of Huoshan Dendrobium nobile according to different species is crucial to quality control and pharmaceutical effect. In this study, as one type of miniature near-infrared (NIR) spectrometer, MicroNIR 1700 was used for absolutely nondestructive determination of NIR spectra of 90 batches of Dendrobium from five species of differ- ent commodity grades. The samples were intact and not smashed. Soft independent modeling of class analogy (SIMCA) pattern recognition based on principal component analysis (PCA) was used to classify and recognize different species of Dendrobium samples. The results indicated that the SIMCA qualitative models established with pretreatment method of standard normal variate transformation (SNV) in the spectra range selected by Qs method had 100% recognition rates and 100% rejection rates. This study demonstrated that a rapid and absolutely non-destructive analytical technique based on MicroNIR 1700 spectrometer was developed for successful discrimination of five different species of Huoshan Dendrobium with acceptable accuracy.

    Full Text Available In the current work I intend to inquire into the internal motives that led the Portuguese seaborne empire to decadence. After making a brief review of the historiography about the decline of Estado da Índia, I proceed to the analysis of the Crown-Church-Nobility triangle in the course of os Descobrimentos, and of their respective roles in the evolution of Portuguese empire. The absolutization of the crown, the over-expansion of the clergy and the empowerment of the aristocracy became the most conspicuous and longstanding features in the Portuguese social fabric after the country launched herself into maritime undertakings, which crippled her agriculture and retarded the industrialization. As a consequence, the rise of bourgeoisie and the transformation of mercantilist economy into the capitalist were obstructed, and a strong adventurous but non-productive spirit mixed with disdain of manual work prevailed both in metropolis and in overseas territories. In conclusion, the Portuguese decadence commenced from within rather than from without, and far prior to Dutch intrusions in Portuguese Asia, which only accelerated the decline.No presente trabalho tenciono indagar as causas internas que dirigiram o império marítimo português à decadência. Depois de uma revisitação da historiografia relativa ao declínio do Estado da Índia, procedo a uma análise do triângulo de Monarca-Igreja-Nobreza durante os Descobrimentos e dos seus papéis respectivos no evoluir do Império português. É verificável que a absolutização da Coroa, a sobre-expansão do clero e a potenciação da aristocracia tornaram-se as características mais salientes e duradouras na estrutura social portuguesa depois de o país se lançar nas façanhas marítimas, do que resultou a agricultura prejudicada e indústria atrasada. A predominância dessas três instituições, por um lado, impediu a ascensão da burguesia, assim dificultando a transformação da economia

    Acidic waters from Cement Creek discharge into the circum-neutral Animas River in a high-elevation region of the San Juan Mountains near Silverton, Colorado. Cement Creek is acidic and enriched in metals and sulfate because it is fed by discharges from abandoned mines and natural mineral deposits. Mixing with the Animas River raises the pH and produces precipitates of iron and aluminum (oxy)hydroxides, which in turn can adsorb other metals. This confluence was studied in 1996 and 1997 to better understand mixing and sorption processes which are common during the neutralization of acidic streams. The photographs in this report show flow braiding and other features that influenced the way the two streams mixed during the late summers of the two years. They also show 'banding' due to incomplete mixing and 'opalescence' due to chemical reactions and the formation of colloidal-size particles in the mixing zone.

    An efficient genetically stable regeneration protocol with increased phytochemical production has been established for Dendrobium nobile, a highly prized orchid for its economic and medicinal importance. Protocorm like bodies (PLBs) were induced from the pseudostem segments using thidiazuron (TDZ; 1.5 mg/l), by-passing the conventional auxin–cytokinin complement approach for plant regeneration. Although, PLB induction was observed at higher concentrations of TDZ, plantlet regeneration from those PLBs was affected adversely. The best rooting (5.41 roots/shoot) was achieved in MS medium with 1.5 mg/l TDZ and 0.25% activated charcoal. Plantlets were successfully transferred to a greenhouse with a survival rate of 84.3%, exhibiting normal development. Genetic stability of the regenerated plants was investigated using randomly amplified polymorphic DNA (RAPD) and start codon targeted (SCoT) polymorphism markers which detected 97% of genetic fidelity among the regenerants. The PIC values of RAPD and SCoT primers were recorded to be 0.92 and 0.76 and their Rp values ranged between 3.66 and 10, and 4 and 12 respectively. The amplification products of the regenerated plants showed similar banding patterns to that of the mother plant thus demonstrating the homogeneity of the micropropagated plants. A comparative phytochemical analysis among the mother and the micropropagated plants showed a higher yield of secondary metabolites. The regeneration protocol developed in this study provides a basis for ex-situ germplasm conservation and also harnesses the various secondary metabolite compounds of medicinal importance present in D. nobile.

    During 1996 to 2000, the Bureau of Land Management, National Park Service, Environmental Protection Agency, United States Department of Agriculture (USDA) Forest Service, and the U.S. Geological Survey (USGS) developed a coordinated strategy to (1) study the environmental effects of historical mining on Federal lands, and (2) remediate contaminated sites that have the greatest impact on water quality and ecosystem health. This dataset provides information that contributes to these overall objectives and is part of the USGS Abandoned Mine Lands Initiative. Data presented here represent ferricrete occurrences and selected iron bogs and springs in the upper Animas River watershed in San Juan County near Silverton, Colorado. Ferricretes (stratified iron and manganese oxyhydroxide-cemented sedimentary deposits) are one indicator of the geochemical baseline conditions as well as the effect that weathering of mineralized rocks had on water quality in the Animas River watershed prior to mining. Logs and wood fragments preserved in several ferricretes in the upper Animas River watershed, collected primarily along streams, yield radiocarbon ages of modern to 9,580 years B.P. (P.L. Verplanck, D.B. Yager, and S.E. Church, work in progress). The presence of ferricrete deposits along the current stream courses indicates that climate and physiography of the Animas River watershed have been relatively constant throughout the Holocene and that weathering processes have been ongoing for thousands of years prior to historical mining activities. Thus, by knowing where ferricrete is preserved in the watershed today, land-management agencies have an indication of (1) where metal precipitation from weathering of altered rocks has occurred in the past, and (2) where this process is ongoing and may confound remediation efforts. These data are included as two coverages-a ferricrete coverage and a bogs and springs coverage. The coverages are included in ArcInfo shapefile and Arc

    Drainage from abandoned and inactive mines and from naturally mineralized areas in the San Juan Mountains of southern Colorado contributes metals to the upper Animas River near Silverton, Colorado. Tracer-injection studies and associated synoptic sampling were performed along two reaches of the upper Animas River to develop detailed profiles of stream discharge and to locate and quantify sources of metal loading. One tracer-injection study was performed in September 1997 on the Animas River reach from Howardsville to Silverton, and a second study was performed in August 1998 on the stream reach from Eureka to Howardsville. Drainage in the upper Animas River study reaches contributed aluminum, calcium, copper, iron, magnesium, manganese, sulfate, and zinc to the surface-water system in 1997 and 1998. Colloidal aluminum, dissolved copper, and dissolved zinc were attenuated through a braided stream reach downstream from Eureka. Instream dissolved copper concentrations were lower than the State of Colorado acute and chronic toxicity standards downstream from the braided reach to Silverton. Dissolved iron load and concentrations increased downstream from Howardsville and Arrastra Gulch, and colloidal iron remained constant at low concentrations downstream from Howardsville. Instream sulfate concentrations were lower than the U.S. Environmental Protection Agency's secondary drinking-water standard of 250 milligrams per liter throughout the two study reaches. Elevated zinc concentrations are the primary concern for aquatic life in the upper Animas River. In the 1998 Eureka to Howardsville study, instream dissolved zinc load increased downstream from the Forest Queen mine, the Kittimack tailings, and Howardsville. In the 1997 Howardsville to Silverton study, there were four primary areas where zinc load increased. First, was the increase downstream from Howardsville and abandoned mining sites downstream from the Cunningham Gulch confluence, which also was measured during

    Full Text Available Flowering in the appropriate season is critical for successful reproduction in angiosperms. The orchid species, Dendrobium nobile, requires vernalization to achieve flowering in the spring, but the underlying regulatory network has not been identified to date. The MADS-box transcription factor DnAGL19 was previously identified in a study of low-temperature treated D. nobile buds and was suggested to regulate vernalization-induced flowering. In this study, phylogenetic analysis of DnAGL9 and the MADS-box containing proteins showed that DnAGL19 is phylogenetically closely related to the SOC1-like protein from orchid Dendrobium Chao Parya Smile, DOSOC1. The orchid clade closed to but is not included into the SOC1-1/TM3 clades associated with either eudicots or monocots, suggesting that DnAGL19 is an SOC1-1/TM3-like ortholog. DnAGL19 was found to be highly expressed in pseudobulbs, leaves, roots and axillary buds but rarely in flowers, and to be substantially upregulated in axillary buds by prolonged low-temperature treatments. Overexpression of DnAGL19 in Arabidopsis thaliana resulted in a small but significantly reduced time to bolting, suggesting that flowering time was slightly accelerated under normal growth conditions. Consistent with this, the A. thaliana APETELA1 (AP1 gene was expressed at an earlier stage in transgenic lines than in wild type plants, while the FLOWERING LOCUS T (FT gene was suppressed, suggesting that altered regulations on these transcription factors caused the weak promotion of flowering. HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENE 1 (HOS1 was slightly activated under the same conditions, suggesting that the HOS1-FT module may be involved in the DnAGL19-related network. Under vernalization conditions, FT expression was significantly upregulated, whereas HOS1 expression in the transgenic A. thaliana has a level similar to that in wild type. Taken together, these results suggest that DnAGL19 controls the action of the

    An exploration into the world of the queer others of gender and sexuality moves us beyond the binary opposition of male/masculinity and female/femininity in our understanding of gender and expands the meaning of gender and sexuality for all humans. A revision of Jungian gender theory that embraces all genders and sexualities is needed not only to inform our clinical work but also to allow us to bring Jungian thought to contemporary gender theory and to cultural struggles such as gay marriage. The cognitive and developmental neurosciences are increasingly focused on the importance of body biology and embodied experience to the emergence of mind. In my exploration of gender I ask how gender comes to be experienced in a developing body and how those embodied gender feelings elaborate into a conscious category in the mind, a gender position. My understanding of emergent mind theory suggests that one's sense of gender, like other aspects of the mind, emerges very early in development from a self-organizing process involving an individual's particular body biology, the brain, and cultural environment. Gendered feeling, from this perspective, would be an emergent aspect of mind and not an archetypal inheritance, and the experiencing body would be key to gender emergence. A revised Jungian gender theory would transcend some of the limitations of Jung's anima/animus (A/A) gender thinking allowing us to contribute to contemporary gender theory in the spirit of another Jung; the Jung of the symbolic, the mythic, and the subtle body. This is the Jung who invites us to the medial place of the soul, bridging the realm of the physical body and the realm of the spirit.

    The purpose of this study was to analyze bacterial decrease after removal of carious tissue in dentine by Er:YAG laser, comparing the results with those achieved by using a tip mounted on a high-rotation device. In view of the difficulty of totally eliminating microorganisms from dentine, even after removing all the carious tissue, and since the presence of a smear layer is a proven fact, it would be extremely convenient to eliminate or to achieve better disinfecting of this notoriously contaminated dentine layer, so as to prevent failure of the restoration process in most cases. For this study, we selected 30 pre-molars and molars with caries rated as medium sized and which required restoration treatment. The teeth were divided in two groups, where 15 teeth received conventional treatment (control group - I) and 15 teeth were treated with Er:YAG laser (Kavo Key Laser) (laser group - II). Microbiologic analysis was used in order to determine presence or absence of bacteria. In group I as well as in group II a previous curettage of part of the dentine caries was performed, and the sample was seeded in an Agar culture medium and incubated at 37 deg C for 72 hours, for a quantitative analysis of bacteria colony forming units (c.f.u.) and qualitative bacterial analysis. After this procedure, carious lesions were removed in group I, using a spherical diamond drill mounted on a high rotation tip, followed by cleaning of the cavity with chlorhexidine digluconate at 2%. In group II, an Er:YAG laser emitting a wave length of 2,94 μm, delivering a 250 mJ energy per pulse at a repetition rate of 2 Hz was used for carious tissue removal. Furthermore in group II (laser), the cavity was conditioned by performing a sweeping at all walls of the preparation with the 50/10 fiber (Kavo), in contact mode, using an energy of 60 mJ per pulse at a frequency of 10 Hz. After removing all caries and performing a cleaning operation in both groups, dentine shavings were collected and seeded

    Full Text Available Purpose – This paper aims to study the node modeling, multi-agent architecture and addressing method for the material conscious information network (MCIN, which is a large-scaled, open-styled, self-organized and ecological intelligent network of supply–demand relationships. Design/methodology/approach – This study models the MCIN by node model definition, multi-agent architecture design and addressing method presentation. Findings – The prototype of novel E-commerce platform based on the MCIN shows the effectiveness and soundness of the MCIN modeling. By comparing to current internet, the authors also find that the MCIN has the advantages of socialization, information integration, collective intelligence, traceability, high robustness, unification of producing and consuming, high scalability and decentralization. Research limitations/implications – Leveraging the dimensions of structure, character, knowledge and experience, a modeling approach of the basic information can fit all kinds of the MCIN nodes. With the double chain structure for both basic and supply–demand information, the MCIN nodes can be modeled comprehensively. The anima-desire-intention-based multi-agent architecture makes the federated agents of the MCIN nodes self-organized and intelligent. The MCIN nodes can be efficiently addressed by the supply–demand-oriented method. However, the implementation of the MCIN is still in process. Practical implications – This paper lays the theoretical foundation for the future networked system of supply–demand relationship and the novel E-commerce platform. Originality/value – The authors believe that the MCIN, first proposed in this paper, is a transformational innovation which facilitates the infrastructure of the future networked system of supply–demand relationship.

    Five picrotoxane sesquiterpenoids belonging to the unusual dendrobine-type (1 and 4) and the picrotoxinin-type (2, 3, and 5) were isolated from the stems of Dendrobium nobile Lindl. Their structures were established by spectroscopic analyses and physical properties. Compound 1 was a new dendrobine analogue. Although the planar structure of 2 and 3 had been reported, their absolute configurations were first determined by single-crystal X-ray diffraction and circular dichroism. Compound 2 exhibited angiogenesis effect against sunitinib-induced damage on intersegmental blood vessels in Tg (flk1: EGFP) and Tg (fli1: nEGFP) transgenic zebrafish at concentrations of 3.13, 6.25, 12.50, and 25.00μM.

    1999-01-01

    Field observations, sampling of mine dumps and mine drainage waters, and laboratory studies of dump materials have been made at mining areas deemed to be on public lands administered by the U. S. Bureau of Land Management (BLM) in the Upper Animas River watershed. Results of chemical analyses of dump materials, leachates of those materials, and surface waters draining mines or dumps provide indications of where acid is generated or consumed, and metal concentrations below mines or dumps. Information on sites previously identified as needing reclamation is reviewed and available geochemical information is used to rank 26 sites into four classes of priority for reclamation. Although there are more than a thousand mining sites (productive mines and prospects) on BLM lands in the Upper Animas River watershed study area, the majority are very small (less than about 70 cubic yards of dump material), are more than 2 miles from a major stream, or so inaccessible as to prohibit reclamation. In the summers of 1997 and 1998 approximately 200 sites were observed and more than 100 of these that appeared to have the potential to geochemically impact the watershed were examined more carefully and sampled. Building upon the prior work of the BLM and associated agencies, this work attempted to identify the most significant sources of mine-related contamination and to rank those sites as to priority for reclamation. These most significant mining areas have been examined within a geologic framework and were evaluated by multiple criteria, including tendency to generate acid and release toxic metals, observed damage to vegetation, potential to release metals based on leach tests, and likelihood of transport into streams of the watershed. No single measurable parameter, such as metal concentration, can be used to rank the sites. Rather, subjective estimates are required to evaluate combinations or interactions among several parameters. The most subjective estimate, while ranking

    Six new octulosonic acid derivatives (1-6) were isolated from the flower heads of Roman chamomile (Chamaemelum nobile). Their structures were elucidated by means of spectroscopic interpretation. The biological activity of the isolated compounds was evaluated toward multiple targets related to inflammation and metabolic disorder such as NAG-1, NF-κB, iNOS, ROS, PPARα, PPARγ, and LXR. Similar to the action of NSAIDs, all the six compounds (1-6) increased NAG-1 activity 2-3-fold. They also decreased cellular oxidative stress by inhibiting ROS generation. Compounds 3, 5, and 6 activated PPARγ 1.6-2.1-fold, while PPARα was activated 1.4-fold by compounds 5 and 6 only. None of the compounds showed significant activity against iNOS or NF-κB. This is the first report of biological activity of octulosonic acid derivatives toward multiple pathways related to inflammation and metabolic disorder. The reported anti-inflammatory, hypoglycemic, antiedemic, and antioxidant activities of Roman chamomile could be partly explained as due to the presence of these constituents.

    La scienza è un’esaltante avventura che è costume raccontare attraverso le gesta dei grandi. Esiste però un’altra storia, altrettanto avvincente ma con poca voce, scritta dai tanti gregari e potenziali campioni cui la sorte, spesso nemmeno troppo cieca, ha negato la gloria. Questo libro parla di uno di loro e del suo piccolo mondo sulla collina di Capodimonte, a Napoli. È la parabola di Arminio Nobile – personaggio notevole eppure poco noto dell’astronomia italiana – svolta sulla scena della nascente astrofisica, in una stagione di grandi transizioni per il Mezzogiorno. Arminio, che era figlio di Giuseppina Guacci, figura di spicco della cultura pre-risorgimentale, e di un valente astronomo della Specola di Capodimonte, scelse di votarsi allo studio del cielo.

    Federal land managers along with local stakeholders in the Upper Animas River watershed near Silverton, Colorado are actively designing and implementing mine waste remediation projects to mitigate the effects of acid mine drainage from several abandoned hard rock metal mines and mills. Local source rocks with high acid neutralization capacity (ANC) within the watershed are of interest to land managers for use in these remediation projects. A suite of representative samples was collected from propylitic to weakly sericitic-altered volcanic and plutonic rocks exposed in outcrops throughout the watershed. Acid-base accounting laboratory methods coupled with mineralogic and geochemical characterization provide insight into lithologies that have a range of ANC and net acid production (NAP). Petrophysical lab determinations of magnetic susceptibility converted to estimates for percent magnetite show correlation with the environmental properties of ANC and NAP for many of the lithologies. A goal of our study is to interpret watershed-scale airborne magnetic data for regional mapping of rocks that have varying degrees of ANC and NAP. Results of our preliminary work are presented here.

    Roman chamomile (Chamaemelum nobile L.) is renowned for its production of essential oils, which major components are sesquiterpenoids. As the important enzyme in the sesquiterpenoid biosynthesis pathway, 3-hydroxy-3-methylglutaryl coenzyme A synthase (HMGS) catalyze the crucial step in the mevalonate pathway in plants. To isolate and identify the functional genes involved in the sesquiterpene biosynthesis of C. nobile L., a HMGS gene designated as CnHMGS (GenBank Accession No. KU529969) was cloned from C. nobile. The cDNA sequence of CnHMGS contained a 1377 bp open reading frame encoding a 458-amino-acid protein. The sequence of the CnHMGS protein was highly homologous to those of HMGS proteins from other plant species. Phylogenetic tree analysis revealed that CnHMGS clustered with the HMGS of Asteraceae in the dicotyledon clade. Further functional complementation of CnHMGS in the mutant yeast strain YSC6274 lacking HMGS activity demonstrated that the cloned CnHMGS cDNA encodes a functional HMGS. Transcript profile analysis indicated that CnHMGS was preferentially expressed in flowers and roots of C. nobile. The expression of CnHMGS could be upregulated by exogenous elicitors, including methyl jasmonate and salicylic acid, suggesting that CnHMGS was elicitor-responsive. The characterization and expression analysis of CnHMGS is helpful to understand the biosynthesis of sesquiterpenoid in C. nobile at the molecular level and also provides molecular wealth for the biotechnological improvement of this important medicinal plant.

    Historical production of metals in the western United States has left a legacy of acidic drainage and toxic metals in many mountain watersheds that are a potential threat to human and ecosystem health. Studies of the effects of historical mining on surface water chemistry and riparian habitat in the Animas River watershed have shown that cost-effective remediation of mine sites must be carefully planned. of the more than 5400 mine, mill, and prospect sites in the watershed, ∼80 sites account for more than 90% of the metal loads to the surface drainages. Much of the low pH water and some of the metal loads are the result of weathering of hydrothermally altered rock that has not been disturbed by historical mining. Some stream reaches in areas underlain by hydrothermally altered rock contained no aquatic life prior to mining.Scientific studies of the processes and metal-release pathways are necessary to develop effective remediation strategies, particularly in watersheds where there is little land available to build mine-waste repositories. Characterization of mine waste, development of runoff profiles, and evaluation of ground-water pathways all require rigorous study and are expensive upfront costs that land managers find difficult to justify. Tracer studies of water quality provide a detailed spatial analysis of processes affecting surface- and ground-water chemistry. Reactive transport models were used in conjunction with the best state-of-the-art engineering solutions to make informed and cost-effective remediation decisions.Remediation of 23% of the high-priority sites identified in the watershed has resulted in steady improvement in water quality. More than $12 million, most contributed by private entities, has been spent on remediation in the Animas River watershed. The recovery curve for aquatic life in the Animas River system will require further documentation and long-term monitoring to evaluate the effectiveness of remediation projects implemented.

    Axonal degeneration is a pathological symbol in the early stage of Alzheimer's disease (AD), which can be triggered by amyloid-β (Aβ) peptide deposition. Growing evidence indicates that deficit of autophagy eventually leads to the axonal degeneration. Our previous studies have shown that Dendrobium nobile Lindl alkaloid (DNLA) had protective effect on neuron impairment in vivo and in vitro; however, the underlying mechanisms is still unclear. We exposed cultured hippocampus neurons to Aβ 25-35 to investigate the effect of DNLA in vitro. Axonal degeneration was evaluated by immunofluorescence staining and MTT assay. Neurons overexpressing GFP-LC3B were used to measure the formation of autophagosome. Autophagosome-lysosome fusion, the lysosomal pH, and cathepsin activity were assessed to reflect autophagy process. Proteins of interest were analyzed by Western blot. DNLA pretreatment significantly inhibited axonal degeneration induced by Aβ 25-35 peptide in vitro. Further studies revealed DNLA treatment increased autophagic flux through promoting formation and degradation of autophagosome in hippocampus neurons. Moreover, enhancement of autophagic flux was responsible for the protective effects of DNLA on axonal degeneration. DNLA prevents Aβ 25-35 -induced axonal degeneration via activation of autophagy process and could be a novel therapeutic target. © 2017 John Wiley & Sons Ltd.

    Full Text Available Peculiarity of the social, economic and legal status of the Don nobility influenced its political alertness and the opposition character of activity. The liberal wing supported the creation of a new world outlook system which was expected to provide the basis for transforming the political system by means of gradual transition to people’s representatives or constitutional form of government. The liberal landowners insisted on the introduction of zemstvo (district council, the solution of the Cossack issue; they strived for liberalization of the military and bureaucratic control of the Cossack troops and demanded the withdrawal of civil government agencies from the competence of the Military department. The liberal nobility actively supported the change of conditions of service for the Cossacks and pressed for easier draft obligation and releasing the Cossack troops from police duties which clashed with the military dignity. The conservative type of liberalism prevailed within the noble class of the DHR that distanced itself from both the left and the right political forces. The liberalism of the Don nobles was also a reflection of social and cultural peculiarities of the Cossacks. The social basis of the Don liberalism differed from the common Russian analogs. As the Cossack class was rather numerous at the Don, and its representatives made up quite an important part of the regional liberal corporation, they influenced its tactics and the political programming considerably.

    A simple HPLC-PAD-MS method was established to quantitatively analyse two spiroether isomers (cis-en-yn-dicycloether and trans-en-yn-dicycloether) and the main coumarin, herniarin, in chamomile herbs, simultaneously. By using this method, the contents of these three compounds in the flowers of two chamomile species, Roman chamomile (Chamaemelum nobile) and pineapple weed (Matricaria matricarioides), as well as in different parts of pineapple weed, were investigated. It was found that the flowers of both herbs contained large amounts of cis-en-yn-dicycloether and trans-en-yn-dicycloether, with the trans-form being more abundant than the cis-form. The leaves of pineapple weed were found to have the highest concentration of cis-en-yn-dicycloether and herniarin than the other parts. HPLC-PAD-MS-guided isolation and identification of other constituents are also discussed.

    Genetic variability in the wild genotypes of Dendrobium nobile Lindl. collected from different parts of Northeast India, was analyzed using a Start Codon Targeted (SCoT) marker system. A total of sixty individuals comprising of six natural populations were investigated for the existing natural genetic diversity. One hundred and thirty two (132) amplicons were produced by SCoT marker generating 96.21% polymorphism. The PIC value of the SCoT marker system was 0.78 and the Rp values of the primers ranged between 4.43 and 7.50. The percentage of polymorphic loci (Pp) ranging from 25% to 56.82%, Nei's gene diversity (h) from 0.08 to 0.15 with mean Nei's gene diversity of 0.28, and Shannon's information index (I) values ranging from 0.13 to 0.24 with an average value of 0.43 were recorded. The gene flow value (0.37) and the diversity among populations (0.57) demonstrated higher genetic variation among the populations. Analysis of molecular variance (AMOVA) showed 43.37% of variation within the populations, whereas 56.63% variation was recorded among the populations. Cluster analysis also reveals high genetic variation among the genotypes. Present investigation suggests the effectiveness of SCoT marker system to estimate the genetic diversity of D. nobile and that it can be seen as a preliminary point for future research on the population and evolutionary genetics of this endangered orchid species of medicinal importance. © 2013.

  9. Medical topics in the De anima commentary of Coimbra (1598) and the Jesuits' attitude towards medicine in education and natural philosophy.

    Early-modern Jesuit universities did not offer studies in medicine, and from 1586 onwards, the Jesuit Ratio studiorum prohibited digressions on medical topics in the Aristotelian curriculum. However, some sixteenth-century Jesuit text books used in philosophy classes provided detailed accounts on physiological issues such as sense perception and its organic location as discussed in Aristotle's De anima II, 7-11. This seeming contradiction needs to be explained. In this paper, I focus on the interst in medical topics manifested in a commentary by the Jesuits of Coimbra. Admittedly, the Coimbra commentary constituted an exception, as the Jesuit college that produced it was integrated in a royal university which had a strong interest in educating physicians. It will be claimed that the exclusion of medicine at Jesuit universities and colleges had its origin in rather incidental events in the course of the foundation of the first Jesuit university in Sicily. There, the lay professors of law and medicine intended to avoid subordination to the Jesuits and thereby provoked a conflict which finally led the Jesuit administration to refrain from including faculties of medicine and law in Jesuit universities. Towards the end of the sixteenth century, a veritable Jesuit animosity towards medicine emerged for philosophical and pedagogical reasons. This development reflects educational concerns within the Society as well as the role of commentaries on Aristotle for early-modern learning.

    Following the release of three million gallons of metals laden surface water from the Gold King Mine in August 2015, surface-water samples were collected in the New Mexico reach of the Animas and San Juan Rivers during 2016 snowmelt and in the Animas River during three 2016 monsoonal storms. These samples were evaluated for dissolved (turbidity and specific conductance can provide insight to changes in concentrations of the river on a finer time scale. Regression models developed for selected sites on the Animas and San Juan Rivers show that flow, turbidity and specific conductance may be useful in understanding the relationship between total metal concentrations and real-time parameters. Surrogates for suspended sediment such as hydroacoustic may also be useful, and potentially the best option in this system, for monitoring the concentration of metals in surface water. Further evaluation of the chemistry of the watershed soils and bedrock, the streambed sediments, and suspended sediments will improve understanding of the geochemical processes in the Animas and San Juan Rivers.

  13. New geochronologic and stratigraphic evidence confirms the paleocene age of the dinosaur-bearing ojo alamo sandstone and animas formation in the San Juan Basin, New Mexico and Colorado

    Dinosaur fossils are present in the Paleocene Ojo Alamo Sandstone and Animas Formation in the San Juan Basin, New Mexico, and Colorado. Evidence for the Paleo-cene age of the Ojo Alamo Sandstone includes palynologic and paleomagnetic data. Palynologic data indicate that the entire Ojo Alamo Sandstone, including the lower dinosaur-bearing part, is Paleocene in age. All of the palynomorph-productive rock samples collected from the Ojo Alamo Sandstone at multiple localities lacked Creta-ceous index palynomorphs (except for rare, reworked specimens) and produced Paleocene index palynomorphs. Paleocene palynomorphs have been identified strati-graphically below dinosaur fossils at two separate localities in the Ojo Alamo Sand-stone in the central and southern parts of the basin. The Animas Formation in the Colorado part of the basin also contains dinosaur fossils, and its Paleocene age has been established based on fossil leaves and palynology. Magnetostratigraphy provides independent evidence for the Paleocene age of the Ojo Alamo Sandstone and its dinosaur-bearing beds. Normal-polarity magnetochron C29n (early Paleocene) has been identified in the Ojo Alamo Sandstone at six localities in the southern part of the San Juan Basin. An assemblage of 34 skeletal elements from a single hadrosaur, found in the Ojo Alamo Sandstone in the southern San Juan Basin, provided conclusive evidence that this assemblage could not have been reworked from underlying Cretaceous strata. In addition, geochemical studies of 15 vertebrate bones from the Paleocene Ojo Alamo Sandstone and 15 bone samples from the underlying Kirtland Formation of Late Creta-ceous (Campanian) age show that each sample suite contained distinctly different abundances of uranium and rare-earth elements, indicating that the bones were miner-alized in place soon after burial, and that none of the Paleocene dinosaur bones ana-lyzed had been reworked. ??

    Reactive oxygen species (ROS)-induced oxidative damage is responsible for viability loss in plant tissues following cryopreservation. Antioxidants may improve viability by preventing or repairing the injury. This work aimed at studying the effect of catalase (CAT) and pyruvate dehydrogenase (PDH), which are involved in ROS metabolism and are differentially expressed during pollen cryopreservation, for cryopreservation of Dendrobium nobile Lindl. 'Hamana Lake Dream' protocorm-like bodies (PLBs). Different concentrations of exogenous CAT or PDH were added at the loading, PVS2 treatment, unloading steps during vitrification-cryopreservation of PLBs. Their survival and regeneration were evaluated and correlated with physiological oxidative indexes. PLB survival increased significantly when CAT and PDH were added separately to the unloading solution at a suitable concentration. CAT at 400 U·ml -1 increased PLB survival and regeneration by 33.5 and 14.6 percent respectively. It had no impact on the production of superoxide anion radical (·O2-) and on superoxide dismutase (SOD) activity, but it reduced the hydrogen peroxide (H 2 O 2 ) and malondialdehyde (MDA) contents and enhanced ascorbic acid (AsA) and endogenous CAT levels compared to PLBs cryopreserved using the standard vitrification protocol (CK1). PDH at 0.1 U·ml -1 significantly improved PLB survival (by 2.5 percent), but it had no marked effect on regeneration compared to the CK1 group. It induced the same variations in ·O2-, AsA and endogenous CAT levels that were observed following CAT addition. However, PDH did not affect the H 2 O 2 and MDA content but significantly increased SOD activity. These results indicate that the addition of 400 U·ml -1 CAT and 0.1 U·ml -1 PDH at the unloading step increased survival of cryopreserved PLBs and that this improvement was associated with scavenging of H 2 O 2 and the repair of oxidative damage. Exogenous CAT also significantly improved PLB regeneration after

    Full Text Available The aim of the museum is to collect and store various objects. It gives the evidences of the past the possibility of "surviving” to the present day. At the same time, the museum should present these materials to the attention of the public, showing the origins of civilization, life in all its complexity, thereby helping the visitor to better understand the world with its secrets. Considering the role of the museum heritage in the development of society, we carried out a study of the collections of the National Museum of the History of Moldova related to the history of the Bessarabian noble families. The Cantacuzins and the Krupensky are two families, belonging to the elite of the nobility and having a centuries-old history. In our study we are considering the Bessarabian branch of these families. From 1991 to 2005 the National Museum of History of Moldova accepted as a gift and purchased important materials reflecting the history of the Cantacuzin family. These materials were collected by Irina Cantacuzin, the wife of the last descendant of the Bessarabian Cantacuzins, Pavel (1902-1992. Of particular value is the collection of documents and photographs of the family of Pavel Cantacuzin, collected and transferred to the museum by A. Krakan in 1993. It consists of about 50 units, among which 36 are originals and copies of photographs relating to the period from the 19th century to 1990. It is this collection that contains a number of photographs with representatives of the family of Krupensky, who were related to the Cantacuzins. In 2001, the NMHM received another collection of documents, photographs and other materials related to the Bessarabian Prince Pavel Cantacuzin. It reflects his life and activities during the period of imprisonment and after rehabilitation. The museum collections hold several things and household items belonging to these families.

    The function of the hypothalamo-pituitary-adrenal axis (HPA) has been widely investigated in mood disorders based on its role in regulating stress response. Particularly, Magnetic Resonance Imaging (MRI) reports have explored pituitary gland (PG) in both bipolar disorder (BD) and major depressive disorder (MDD). In this context, the present review summarizes the results from MRI studies with the final aim of commenting on the presence of common or distinct PG structural alterations between these two disabling illnesses. A bibliographic search on PUBMED of all MRI studies exploring PG volumes in BD and MDD as well as first-degree relatives (RELs) from 2000 up to October 2016 was performed. Following the screening process of the available literature it can be said that a) PG enlargement has been found in both BD and MDD, therefore potentially representing a common neurobiological marker characterizing mood disorders, and b) PG volumes are moderated by age and sex in both illnesses, although the direction and the extent of this moderation are still not fully clear. Few MRI studies with heterogeneous results. These hypotheses must be taken with caution especially because the heterogeneity of the results of the studies reviewed does not allow for a definite answer about the role of PG in affective disorders. Therefore, larger longitudinal studies investigating PG volumes in BD and MDD patients at the early phases of the illness, by considering females and males separately, are needed to further corroborate these findings.

  3. Net Acid Production, Acid Neutralizing Capacity, and Associated Mineralogical and Geochemical Characteristics of Animas River Watershed Igneous Rocks Near Silverton, Colorado

    2008-01-01

    This report presents results from laboratory and field studies involving the net acid production (NAP), acid neutralizing capacity (ANC), and magnetic mineralogy of 27 samples collected in altered volcanic terrain in the upper Animas River watershed near Silverton, Colo., during the summer of 2005. Sampling focused mainly on the volumetrically important, Tertiary-age volcanic and plutonic rocks that host base- and precious-metal mineralization in the study area. These rocks were analyzed to determine their potential for neutralization of acid-rock drainage. Rocks in the study area have been subjected to a regional propylitic alteration event, which introduced calcite, chlorite (clinochlore), and epidote that have varying amounts and rates of acid neutralizing capacity (ANC). Locally, hydrothermal alteration has consumed any ANC and introduced minerals, mainly pyrite, that have a high net acid production (NAP). Laboratory studies included hydrogen pyroxide (H2O2) acid digestion and subsequent sodium hydroxide (NaOH) titration to determine NAP, and sulfuric acid (H2SO4) acid titration experiments to determine ANC. In addition to these environmental rock-property determinations, mineralogical, chemical, and petrographic characteristics of each sample were determined through semiquantitative X-ray diffractometry (Rietveld method), optical mineralogy, wavelength dispersive X-ray fluorescence, total carbon-carbonate, and inductively coupled plasma?mass spectrometric analysis. An ANC ranking was assigned to rock samples based on calculated ANC quantity in kilograms/ton (kg/t) calcium carbonate equivalent and ratios of ANC to NAP. Results show that talus near the southeast Silverton caldera margin, composed of andesite clasts of the Burns Member of the Silverton Volcanics, has the highest ANC (>100 kg/t calcium carbonate equivalent) with little to no NAP. The other units found to have moderate to high ANC include (a) andesite lavas and volcaniclastic rocks of the San Juan

    Mine planning efforts have historically overlooked the possible acid neutralizing capacity (ANC) that local igneous rocks can provide to help neutralize acidmine drainage. As a result, limestone has been traditionally hauled to mine sites for use in neutralizing acid drainage. Local igneous rocks, when used as part of mine life-cycle planning and acid mitigation strategy, may reduce the need to transport limestone to mine sites because these rocks can contain acid neutralizing minerals. Igneous hydrothermal events often introduce moderately altered mineral assemblages peripheral to more intensely altered rocks that host metal-bearing veins and ore bodies. These less altered rocks can contain ANC minerals (calcite-chlorite-epidote) and are referred to as a propylitic assemblage. In addition, the carbon contents of soils in areas of new mining or those areas undergoing restoration have been historically unknown. Soil organic carbon is an important constituent to characterize as a soil recovery benchmark that can be referred to during mine cycle planning and restoration. This study addresses the mineralogy, ANC, and leachate chemistry of propylitic volcanic rocks that host polymetallic mineralization in the Animas River watershed near the historical Silverton, Colorado, mining area. Acid titration tests on volcanic rocks containing calcite (2 – 20 wt %) and chlorite (6 – 25 wt %), have ANC ranging from 4 – 146 kg/ton CaCO3 equivalence. Results from a 6-month duration, kinetic reaction vessel test containing layered pyritic mine waste and underlying ANC volcanic rock (saturated with deionized water) indicate that acid generating mine waste (pH 2.4) has not overwhelmed the ANC of propylitic volcanic rocks (pH 5.8). Sequential leachate laboratory experiments evaluated the concentration of metals liberated during leaching. Leachate concentrations of Cu-Zn-As-Pb for ANC volcanic rock are one-to-three orders of magnitude lower when compared to leached solution from

    Full Text Available This paper tries to make a first approach to the concept and exercise of power by women of the aristocracy of the late medieval Castile. To do this I will use as a source of wills analysis of noblewomen and I will rely on one of the new paradigms recently coined by historians of women studies: The Queenship. This innovative approach articulates the analysis of female power around the following scheme: the definition of the power of women, both in its more traditional aspect (marriages, alliances, lineage, and the newest (client networks, influences, «partnership»... or facet «informal» of female power. The analysis of the aspects that we might consider as «formal power», the «houses» of the queens and the study of their ability to manage and administer their own property. Finally, the construction of a model of «Queen» and the importance, meaning, symbolism and function that takes the same in the late medieval political game. The goal is to bring this model to the Castilian aristocracy through said tripartite scheme.

While human intellectual activity was said to be 'above time' during the Middle Ages, Renaissance scholars such as Marcantonio Genua (1491-1563), Giulio Castellani (1528-1586), Antonio Montecatini (1537-1599) and Francesco Piccolomini (1520-1604), greatly influenced by the Simplician and Alexandrist interpretations of Aristotle's works, proposed alterna- tive conceptions based on the interpretation of De anima 3.6 (430b 7-20) according to which intellectual acts happen in a both 'undivided' and 'divisible time'. In order to explain Aristotle's puzzling claim, they were led to conceive of intellectual activity as a process similar to sensation, corresponding to a certain lapse of time (Castellani), an instant (Montecatini), or a mix of instantaneousness and concrete duration (Piccolomini), depending on their theoretical options.

  13. Gestão de pessoas na indústria criativa: o caso dos estúdios de animação brasileiros

    Marta Corrêa Machado

    Full Text Available Resumo Esta pesquisa visa entender a gestão de pessoas na indústria criativa a partir do estudo de um de seus segmentos, os estúdios de animação. Partindo da conceituação de Chaston (2008 de indústria criativa como o encontro entre negócio e cultura, observou-se o dilema entre a realização artística e os objetivos comerciais presente também nesse segmento da indústria. No estudo, pudemos aprofundar o entendimento sobre como esse dilema se reflete na operação da gestão de pessoas nesses estúdios brasileiros. Para entender essa questão foi conduzida uma pesquisa qualitativa através de estudos de casos em quatro produtoras nacionais nos quais foram entrevistados um funcionário e um sócio de cada empresa. Os dados encontrados apontam que ainda é incipiente a gestão de pessoas nesses ambientes, embora esteja presente a noção de que esses são os recursos principais que movem essas empresas. Foi observado ainda que a retenção dos colaboradores ocorre muito mais pela sua identificação com a atividade em si do que por outras retribuições, como salário ou garantias trabalhihstas.

    Presumably, progression of developmental retinal vascular disorders is mainly driven by persistent ischemia/hypoxia. An investigation into vision-threatening retinal ischemia remains important. Our aim was to evaluate, in relation to retinal ischemia, protective effects and mechanisms of Dendrobium nobile Lindley (DNL) and its bibenzyl component moscatilin. The therapeutic mechanisms included evaluations of levels of placental growth factor (PLGF) and Norrie disease protein (NDP). An oxygen glucose deprivation (OGD) model involved cells cultured in DMEM containing 1% O 2 , 94% N 2 and 0 g/L glucose. High intraocular pressure (HIOP)-induced retinal ischemia was created by increasing IOP to 120 mmHg for 60 min in Wistar rats. The methods included electroretinogram (ERG), histopathology, MTT assay and biochemistry. When compared with cells cultured in DMEM containing DMSO (DMSO+DMEM), cells subjected to OGD and pre-administrated with DMSO (DMSO+OGD) showed a significant reduction in the cell viability and NDP expression. Moreover, cells that received OGD and 1 h pre-administration of 0.1 μM moscatilin (Pre-OGD Mos 0.1 μM) showed a significant counteraction of the OGD-induced decreased cell viability. Furthermore, compared with the DMSO+OGD group (44.54 ± 3.15%), there was significant elevated NDP levels in the Pre-OGD Mos 0.1 μM group (108.38 ± 29.33%). Additionally, there were significant ischemic alterations, namely reduced ERG b-wave, less numerous retinal ganglion cells, decreased inner retinal thickness, and reduced/enhanced amacrine's ChAT/Müller's GFAP or vimentin immunolabelings. Moreover, there were significantly increased protein levels of HIF-1α, VEGF, PKM2, RBP2 and, particularly, PLGF (pg/ml; Sham vs. Vehicle: 15.11 ± 1.58 vs. 39.53 ± 5.25). These ischemic effects were significantly altered when 1.0 g/Kg/day DNL (DNL1.0 + I/R or I/R+ DNL1.0) was applied before and/or after ischemia, but not vehicle (Vehicle+I/R). Of

    Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by deficits in cognitive and emotional self-control. Optical technique acquisitions, such as near infrared spectroscopy (NIRS), seem to be very promising during developmental ages, as they are non- invasive techniques and less influenced by body movements than other neuroimaging methods. Recently, these new techniques are being widely used to measure neural correlates underlying neuropsychological deficits in children with ADHD. In a short series of articles, we will review the results of functional NIRS (fNIRS) studies in children with ADHD. The present brief review will focus on the results of the fNIRS studies that investigate cortical activity during neuropsychological and/or emotional tasks. According to the reviewed studies, children and adolescents with ADHD show peculiar cortical activation both during neurological and emotional tasks, and the majority of the reviewed studies revealed lower prefrontal cortex activation in patients compared to typically developmental controls. a consistent interpretation of these results is limited by the substantial methodological heterogeneity including patients' medication status and washout period, explored cerebral regions, neuropsychological tasks, number of channels and sampling temporal resolutions. fNIRS seems to be a promising tool for investigating neural substrates of emotional dysregulation and executive function deficits in individuals with ADHD during developmental ages.

    presumed to be impacted by historical mining activities. The Animas River watershed (fig. 1) was selected by the State and Federal agencies as one of two watersheds in the U.S. to be studied in detail by the USGS in the AML Initiative. Beginning in October 1997, each of the four Divisions of the USGS (Water Resources, Geologic, Biological Resources, and National Mapping) initiated a collaborative integrated science study of the watershed. Funds were provided from USGS base funding to each of the four Divisions in response to the priorities set by Congressional action and within the flexibility provided by the budgetary framework funding individual research programs. The AML Initiative provides for a five-year focused scientific effort in the two watersheds with final synthesis of the scientific results from each to be published in 2001. Publications are released on the AML web site on a regular basis (http://amli.usgs.gov/amli). On March 29, 2000, the USGS hosted a meeting for the BLM and USFS to discuss remediation options that were under consideration for the summer of 2000. The purpose of this report is to provide an overview of the scientific rational provided by the USGS to meet objective one above, and to summarize our preliminary interpretations of our data. Additional information from sites on private lands have been collected by the State of Colorado, EPA, and the ARSG. Unfortunately, these data have not been fully supplied to the USGS so our conclusions are based only upon our data. These interpretations provide science-based constraints on possible remediation options to be considered by the FLMA, the State, and local property owners in the Animas River watershed. The report is presented in outline format to facilitate discussion of remediation options at the March 29, 2000 meeting. Not all historical mining sites within the watershed are on public lands. This should not be construed to be a final report of the USGS

A animação Peixonauta dá destaque a questões ambientais: introdução de espécies exóticas e domésticas na natureza, e o modo como essa prática afeta o meio ambiente; poluição das águas, solo e ar; e certos fenômenos naturais. Realizado na intersecção da Educação, da Educação Ambiental, dos Estudos Culturaise dos Estudos de Mídia, este estudo problematiza o modo como este desenho ensina quais ações e quais problemas devem ser considerados relativamente aos chamados ambientes naturais. O corpus analítico compõe-se de 30 episódios que evidenciam quatro temáticas ambientais: a reciclagem de materiais; b introdução de espécies exóticas; c poluição; d mudanças climáticas e problemas associados. Os resultados sugerem que o Discovery Kids prática uma espécie de “Educação Ambiental corporativa” ao introduzir e valer-se de temas “verdes” em sua programação. Em Peixonauta, tal intenção fica evidenciada. Algumas personagens representam sujeitos a serem conscientizados ambientalmente; outros ensinam o que é ser “ambientalmente responsável”. Há, também, os que detêm conhecimentos legitimados. Além disso, a tecnologia é colocada em destaque como meio seguro e rápido para a solução dos problemas ambientais. Mas, ao mesmo tempo, ao simplificar o encontro de soluções, a série operaria na direção da naturalização/banalização dos problemas ambientais, provocando o seu apagamento.

  20. Hortuli animae from the Years 1516 and 1548 in the Collection of the National and University Library of Ljubljana: The Pre-Reformation Prayer Book and its Lutheran Transformation

    Full Text Available The collection of rare prints at the National and University Library of Ljubljana contains two small printed prayer books entitled Hortulus animae. One is from 1516 and the other from 1548, and both are embellished with numerous woodcut illustrations. On closer inspection, the similarities between the booklets soon vanish: the older one belongs to the golden age of pre-Reformation prayer books of the first two decades of the sixteenth century, and the second one to the Reformation. Nevertheless, both examples have so far been ignored by scholars. The Latin prayer book dated 1516 was published in Mainz by Johann Schöfer. It belongs to the important and numerous group of pre-Reformation prayer books, among which Hortulus animae was most successful. This type derives from books of hours, with adjustments to central European devotional practices. Hortulus animae is a compendium of diverse devotional texts designed to equip Christians for every situation in which they might need divine assistance. An important role was also played by numerous illustrations, as proven by some prayers that explicitly demand recitation before a specific image (the prayers of St. Gregory the Great and St. Anne. The importance of these booklets is confirmed by the importance of some of the artists that provided illustrations, such as Albrecht Dürer, Hans Burgkmair the Elder, and Hans Holbein the Younger. The illustrations in the Ljubljana prayer book were all executed by a single master, which was not common for this type of publication. His name and his other works are unknown, although the quality of his woodcuts surpasses many in other series used at this time. The special value of this prayer book also lies in numerous traces left by its owners, the most impressive being the drawing of the coat of arms on the back cover. The second Hortulus animae with German text was published in Wittenberg in 1548 by the important Protestant publisher Georg Rhau. The texts, partly

Há algumas experiências no Brasil e no exterior em que as crianças participam desse processo, ora experimentando a linguagem, ora produzindo conteúdos. Pensando sobre o alcance lúdico, imaginativo e criativo do cinema aliado à cultura da infância, foram desenvolvidos encontros de pesquisa com crianças dos 5ºs anos do Ensino Fundamental em uma escola pública de Campo Grande, Mato Grosso do Sul, no âmbito de pesquisas com apoio do CNPq e de projetos de extensão, nos anos de 2010 a 2013. Nesses encontros, juntamente com as questões relacionadas à linguagem cinematográfica, outras temáticas foram priorizadas para garantir a construção da narrativa dos filmes, entre elas, gênero, sexualidade, diversidade/diferença e violências contra crianças. No decorrer do processo, produziu-se juntamente com as crianças roteiros, cenários, construção de personagens e demais processos de produção e planejamento de pós-produção dos filmes de animação: Jéssica e Júnior no mundo das cores (2010; A Princesa Pantaneira (2012; Queityléia em perigos reais (2012; Direitos das crianças: uma aventura intergaláctica (2013; e João e Maria: dos contos à realidade (2013.

The anima and animus are described by Jung as elements of his theory of the collective unconscious, a domain of the unconscious that transcends the personal psyche. In the unconscious of the male, it finds expression as a feminine inner personality: anima; equivalently, in the unconscious of the female it is expressed as a masculine inner personality: animus. The anima (animus can be identified as the totality of the unconscious feminine psychological qualities that a male possesses; or the masculine ones possessed by the female. It is an archetype of the collective unconscious and not an aggregate of father or mother, brothers, sisters, aunts, uncles or teachers, though these aspects of the personal unconsciousÖmer Seyfettin has written this story after the occupation of Ġzmir by Greeks.

    This geologic map covers four 7.5-minute quadrangles-The Wall, NM-CO (New Mexico-Colorado), Vermejo Park, NM-CO, Ash Mountain, NM, and Van Bremmer Park, NM. The study area straddles the boundary between the eastern flank of the Sangre de Cristo Mountains and the western margin of the Raton Basin, with about two-thirds of the map area in the basin. The Raton Basin is a foreland basin that formed immediately eastward of the Sangre de Cristo Mountains during their initial uplift, in the Late Cretaceous through early Eocene Laramide orogeny. Subsequently, these mountains have been extensively modified during formation of the Rio Grande rift, from late Oligocene to present. The map area is within that part of the Sangre de Cristo Mountains that is called the Culebra Range. Additionally, the map covers small parts of the Devil's Park graben and the Valle Vidal half-graben, in the northwestern and southwestern parts of the map area, respectively. These two grabens are small intermontaine basins, that are satellitic to the main local basin of the Rio Grande rift, the San Luis Basin, that are an outlying, early- formed part of the rift, and that separate the Culebra Range from the Taos Range, to the southwest.

Mientras se hace visible un incremento de poder de la oligarquía gobernante, en particular de don Álvaro, lo que comienza a provocar reticencias en ese grupo, las Cortes de Madrid de 1435 denuncian ásperamente el incumplimiento de importantes compromisos contraídos en Zamora, especialmente los que pretendían limitar el control de la vida municipal por los grandes, y replantean de nuevo viejos problemas de carácter fiscal, económico, jurídico, y administrativo. Aquella desconfianza y este descontento, además de la patente diferencia de objetivos de los miembros de la oligarquía, harán inviable todo proyecto de reforzamiento institucional.Only a small part of the great institutional reform project approved in the Cortes of Zamora was actually implemented, leading to dissatisfaction and the ensuing protests of the Cortes of Madrid of 1433. On the other hand, the Ordinances of Segovia were to provide an essential, if only partial, solution to this issue. While the ruling oligarchy —especially the faction led by Álvaro de Luna— visibly increased its power, leading to political animosities, the parliament of Madrid of 1435 denounced the neglect of important commitments adopted in Zamora. These concern the limits to municipal control by the high nobility, and once again the Cortes reiterates the need to deal with previously unresolved fiscal, economic, legal, and administrative issues. Along with irreconcilable differences in the objectives of the members of the oligarchy, distrust and dissatisfaction made unfeasible any project of institutional reform.

    A geologic and geochemical investigation and a survey of mines and prospects were conducted to evaluate the mineral-resource potential of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas Counties, in south-central Colorado. Anomalous gold, silver, copper, lead, and zinc concentrations in rocks and in stream sediments from drainage basins in the vicinity of the old mines and prospects on West Spanish Peak indicate a substantiated mineral-resource potential for base and precious metals in the area surrounding this peak; however, the mineralized veins are sparse, small in size, and generally low in grade. There is a possibility that coal may underlie the study area, but it would be at great depth and it is unlikely that it would have survived the intense igneous activity in the area. There is little likelihood for the occurrence of oil and gas because of the lack of structural traps and the igneous activity.

    Highlights: ► Localized corrosion of a new N-based tool alloy (Fe–Cr–V–N) has been studied. ► One-pass mode of scanning Kelvin force microscopy (KFM) was used in the study. ► The focus was on correlation between microstructure and localized corrosion. - Abstract: Microstructure influence on corrosion behavior of an N-based tool alloy (Fe–Cr–V–N) has been studied. Electron microscopy analysis showed two types of hard phases in the alloy. One-pass mode scanning Kelvin force microscopy (KFM) was used to investigate relative nobility of the hard phases. Volta potential mapping indicates higher nobility for the hard phases than the alloy matrix, and, the V- and N-rich particles exhibit the highest Volta potential. Post-polarization analysis by SEM revealed localized dissolution initiated in matrix regions adjacent to hard phase particles, and the boundary region surrounding the Cr- and Mo-rich particles is more prone to localized corrosion.

    Full Text Available The proposal about human being's supreme objective offered by Avempace –philosopher and Aristotelian commentator–, consists on the absolute union of both: the subject's intellect-soul and the agent intellect, the latter characterized by being one, separated, eternal, in addition that in itself contains the universal spiritual forms of all things. For this reason the soul's immateriality as well as its immortality are guaranteed, due to the intellect's absolute spirituality. Because of the corruption given in societies and political practices, this final objective is reached through the best way of life, which consists on solitude and reflection; only this way the highest perfection is acquired. After understanding the relevance Avempace granted to the agent intellect, Albert the Great denied the possibility of union with the mentioned intellect, due to the abolition of all plurality as well as the dissolution of all individuality.

The speaking machines, and then the vocoder, are substantially formed by a controlled part and an automatic part; in the voder, the synthetic speaker is directly controlled by a human being, conversely in the vocoder an authomatic process is implemented. Through historical examples such as the ‘automata’ by Mical, Kratzenstein, von Kempelen, Wheatstone, Helmoltz, until the invention of the Dudley’s vocoder, are described a growth and a stratification of devices and synthesizers applied to varied fields (signal representation, encrypted transmission, medical apparatus, cybernetic, music. The historical period treated ideally ends with Dolson’s article written in 1986, “The Phase Vocoder: A Tutorial”. Through musical examples is described the origin of control data handling in composition. The musical application of the phase vocoder describes the distinction between control and synthesis better than other technologies. Both control (parameter values and synthesis (instruments design are compositional problems that involve all the electroacoustic music composers.

    Highlights: ► The shift in binding energy of Cu and Au lines in CuAu alloys is opposite to expected from the nobility of the elements. ► The magnitude of the chemical shifts of the metal lines in CuAu alloys is strongly influenced by finite size effects and disorder. ► Cu 3s and/or Au 4f cross-sections are not well described by theory (Scofield). The Cu 3s photoabsorption cross-section seems to be strongly overestimated. ► We find/confirm that (CuAu) dealloying proceeds into depth like a spinodal decomposition. -- Abstract: We studied pristine and leached ultra-thin Cu{sub x}Au (x ≈ 4) films by hard X-ray photoelectron spectroscopy. The Au 4f and Cu 3s core levels show a shift in binding energy which is opposite to expected from the nobility of the elements, which is explained by charge transfer involving differently screening s and d valence levels of the elements [W. Eberhardt, S.C. Wu, R. Garrett, D. Sondericker, F. Jona, Phys. Rev. B 31 (1985) 8285]. The magnitude of the chemical shifts of the metal lines is strongly influenced by the finite size and disorder of the films. Angular dependent photoelectron emission allowed to assess the alloy composition as a function of depth larger than 5 nm. The potential controlled dealloying proceeds into depth like a spinodal decomposition with Cu going into solution and the remaining Au accumulating in the surface region. The compositional gradient did not lead to a significant broadening of the metal photoelectron lines suggesting a non-local screening mechanism.

  17. Electrochemical, Polarization, and Crevice Corrosion Testing of Nitinol 60, A Supplement to the ECLSS Sustaining Materials Compatibility Study

    In earlier trials, electrochemical test results were presented for six noble metals evaluated in test solutions representative of waste liquids processed in the Environmental Control and Life Support System (ECLSS) aboard the International Space Station (ISS). Subsequently, a seventh metal, Nitinol 60, was added for evaluation and subjected to the same test routines, data analysis, and theoretical methodologies. The previous six test metals included three titanium grades, (commercially pure, 6Al-4V alloy and 6Al-4V low interstitial alloy), two nickel-chromium alloys (Inconel(RegisteredTrademark) 625 and Hastelloy(RegisteredTrademark) C276), and one high-tier stainless steel (Cronidur(RegisteredTrademark) 30). The three titanium alloys gave the best results of all the metals, indicating superior corrosive nobility and galvanic protection properties. For this current effort, the results have clearly shown that Nitinol 60 is almost as noble as titanium, being very corrosion-resistant and galvanically compatible with the other six metals electrochemically and during long-term exposure. is also quite noble as it is very corrosion resistant and galvanically compatible with the other six metals from both an electrochemical perspective and long-term crevice corrosion scenario. This was clearly demonstrated utilizing the same techniques for linear, Tafel and cyclic polarization, and galvanic coupling of the metal candidate as was done for the previous study. The high nobility and low corrosion susceptibility for Nitinol 60 appear to be intermediate to the nickel/chromium alloys and the titanium metals with indications that are more reflective of the titanium metals in terms of general corrosion and pitting behavior.

    2014-01-01

    To find the true story of the orrery, this book takes the reader to the vibrant, tumultous London of the 1600s. A mechanical model that shows the movements of the Moon and planets, the orrery takes its name from the Boyle family – the Earls of Orrery. Here is the fascinating story of the origins of this intricate device. Orreries are found everywhere. They appear in paintings, on the side of royal clocks, in stately home hallways, and of course, in museums all over the world. Scientific instruments to demonstrate the movements of the planets and predict their positions using measuring devices, they were devised largely by clockmakers, but many others played a role too and are given due credit. The story of the Boyles is not just relevant to a tiny corner of Ireland, but spans history. “Orrery” highlights the process of discovery and humankind’s universal fascination with the heavens, providing a fascinating example of the relationship between innovative thinking (invention) and precision enginee...

    The study area comprises the Humboldt River Basin and adjacent areas, with emphasis on mining areas relatively close to the Humboldt River. The basin comprises about 16,840 mi2 or 10,800,000 acres. The mineral resources of the Humboldt Basin have been investigated by many scientists over the past 100 years, but only recently has our knowledge of regional geology and mine geology been applied to the understanding and evaluation of mining effects on water and environmental quality. The investigations reported here apply some of the techniques and perspectives developed in the Abandoned Mine Lands Initiative (AMLI) of the U.S. Geological Survey (USGS), a program of integrated geological-hydrological-biological-chemical studies underway in the Upper Animas River watershed in Colorado and the Boulder River watershed in, Montana. The goal of my studies of sites and districts is to determine the character of mining-related contamination that is actively or potentially a threat to water quality and to estimate the potential for natural attenuation of that contamination. These geology-based studies and recommendations differ in matters of emphasis and data collection from the biology-based assessments that are the cornerstone of environmental regulations.

    Full Text Available Needle shaped SbTeI crystals were obtained by solid state reaction. Electrical resistance was measured in the temperature range of 4 K to 550 K. SbTeI shows a metallic behavior from 4 K to 300 K, and at higher temperature (>300 K, it shows semiconducting behavior. Unlike SbSI, this material shows almost zero resistance around 550 K. It shows a piezoelectric behavior with a capacitance of 717 pF and its carrier density and nobilities are found to be 2.12 × 1016 cm−3 and 1.01 cm2/(V·s, respectively. Crystals of SbTeI are characterized by XRD, SEM, and Raman analysis. Electrical activation energy is found to be 0.52 eV. It is suggested that this material may be studied for its application as a superconductor with Tc higher than room temperature.

  6. [Roald Amundsen--a study of personality].

    Science.gov (United States)

    Albretsen, C S

    1996-12-10

    Roald Amundsen is the most famous of the Norwegian polar explorers. His ancestors came from a group of islands south-east of the Oslofjord. From being fishermen and sailors, they progressed to becoming captains and shipowners in the course of two generations. Amundsen's father, Jens, stayed at sea until his ship went down with all the crew. Roald was 14 years of age at the time, the youngest of four competing brothers. Jens had left the close-knit local family community before that, and bought a flat in the capital, Oslo, so that his sons could get a better education. Roald's mother wanted him to study medicine. He did as she wished for a time, but was not at all interested. When his mother died, he abruptly left the university and went to sea, which had been the tradition in his family for decades. As a young boy he was an admirer of Sir John Franklin and his explorers of the Northwest Passage. Fridtjof Nansen became his ideal. The biographies about Roald Amundsen are very diverging--some hold him a hero, others reflect a strongly critical attitude. Here, the author tries to define his personality and places him firmly within the narcissistic domain. His tendency to seek the company of married women, but to take immediate flight when they really became interested reflects an Oedipus complex from before puberty. The tragic death of his father, the sea captain, may have been a supposition; puberty can be seen as a period of coping with ambivalence towards an earlier idealized father. His genius combined ambitious goals with a sharp eye for details as regards the equipment used in his expeditions. In his travels in the Arctic and the Antartic he was driven forward by the energy of the nation. His heroic death, trying to save his earlier "enemy", Nobile, was probably caused by an urge for self-destruction.

    Dendrobium is a commonly used and precious herb in Traditional Chinese Medicine. The high biodiversity of Dendrobium and the therapeutic needs require tools for the correct and fast discrimination of different Dendrobium species. This study investigates Fourier transform infrared spectroscopy followed by cluster analysis for discrimination and chemical phylogenetic study of seven Dendrobium species. Despite the general pattern of the IR spectra, different intensities, shapes, peak positions were found in the IR spectra of these samples, especially in the range of 1800-800 cm-1. The second derivative transformation and alcoholic extracting procedure obviously enlarged the tiny spectral differences among these samples. The results indicated each Dendrobium species had a characteristic IR spectra profile, which could be used to discriminate them. The similarity coefficients among the samples were analyzed based on their second derivative IR spectra, which ranged from 0.7632 to 0.9700, among the seven Dendrobium species, and from 0.5163 to 0.9615, among the ethanol extracts. A dendrogram was constructed based on cluster analysis the IR spectra for studying the chemical phylogenetic relationships among the samples. The results indicated that D. denneanum and D. crepidatum could be the alternative resources to substitute D. chrysotoxum, D. officinale and D. nobile which were officially recorded in Chinese Pharmacopoeia. In conclusion, with the advantages of high resolution, speediness and convenience, the experimental approach can successfully discriminate and construct the chemical phylogenetic relationships of the seven Dendrobium species.

    Angiogenesis is a process by which new blood vessels are formed from the pre-existing vasculature, and it is a key process that leads to tumour development. Some studies have recognized phenolic compounds as chemopreventive agents; flavonoids, in particular, seem to suppress the growth of tumor cells modifying the cell cycle. Herein, the antiangiogenic activity of Roman chamomile (Chamaemelum nobile L.) extracts (methanolic extract and infusion) and the main phenolic compounds present (apigenin, apigenin-7-O-glucoside, caffeic acid, chlorogenic acid, luteolin, and luteolin-7-O-glucoside) was evaluated through enzymatic assays using the tyrosine kinase intracellular domain of the Vascular Endothelium Growth Factor Receptor-2 (VEGFR-2), which is a transmembrane receptor expressed fundamentally in endothelial cells involved in angiogenesis, and molecular modelling studies. The methanolic extract showed a lower IC50 value (concentration that provided 50% of VEGFR-2 inhibition) than the infusion, 269 and 301 μg mL(-1), respectively. Regarding phenolic compounds, luteolin and apigenin showed the highest capacity to inhibit the phosphorylation of VEGFR-2, leading us to believe that these compounds are involved in the activity revealed by the methanolic extract.

    Full Text Available Nella dimensione concettuale e terapeutica della psicologia analitica il lavoro con le immagini si pone come una sorte di spartiacque che caratterizza la specificità e l’identità della clinica junghiana, terreno di incontro col mondo delle psicosi, avvicinandosi al mondo dei deliri e delle allucinazioni come aspetti fenomenologici dove la dimensione personale si interseca con quella archetipica e il senso della propria esistenza ha potuto trovare un contenitore forse unicamente attraverso la voce dei deliri e delle immagini patologizzanti. In tal senso, le immagini accompagnano lungo il viaggio della vita, albergano nei ricordi delle storie prive di fiducia e di amore e possono condurre alla follia oppure rappresentare una ancora di salvezza in un mare tempestoso su una nave senza nocchiero. L'immaginazione è quindi da intendersi come attività creatrice, forza propulsiva che spinge e conduce l'individuo a mettersi in gioco e a valorizzare la dimensione interna non solo come portatrice di aspetti distruttivi e mostruosi, ma anche come possibilità di immaginare e non fantasticare la possibilità che ci possa essere uno spazio per la trasformazione del proprio passato in una storia riscritta in un altro modo, con un altro significato che sia quello dell'unione e non della frantumazione schizofrenica.

    Universities' responsibility to ensure academic integrity is frustrated by software and communication tools that facilitate content reuse coupled with a growing international essay writing economy. A wide range of behaviours constitute academic dishonesty and while a complex phenomenon to examine, existing evidence suggests that there is sufficient proliferation (both in volume and variety) of these behaviours among Australian university students to warrant concern. This proliferation presents faculty and staff with new challenges in ensuring academic integrity. This paper reports findings of a nationwide cross-sectional survey of 361 students enrolled in an Australian nursing degree program and describes the extent of academic dishonesty among those surveyed. An online survey adapted from previous work was used to collect data on academic dishonesty, professional dishonesty and social desirability bias. Analysis of this data enabled identification of the prevalence of dishonesty, relationships between individual characteristics and dishonest behaviours, associations between academic and professional dishonesty, and the impact of deterrents to such behaviour. Plagiarism was the most frequently reported form of academic misconduct. Most participants indicated that threat of severe punishment and signing of verification statements would deter undesirable academic behaviour. Despite this, a relatively high proportion of students reported engaging in at least one form of academic misconduct, the likelihood of which was higher among younger age groups. Of concern was that a correlation was found between academic and professional misconduct, the most common being the recording of inaccurate or fabricated vital signs and breaching client privacy. In health professional education, there is a tendency to assume that the nobility of these disciplines would result in a lower incidence of cheating behaviours. The findings of this study support existing literature that refutes

Comparison is made with all available experimental data as well as other theoretical results. Our present theoretical investigation clearly demonstrates that there is a good agreement between our present R-matrix results and RR-matrix results as well as with other results in the case of neon which reflects that the correlation and relativity are not important in this case, in the energy range of present consideration. Whereas in the case of xenon (Z=54), the independent-particle approximation completely breaks down, i.e., HF cross sections are both qualitatively as well as quantitatively incorrect in the entire energy range which exhibit that the multielectron correlation as well as relativity are both important but interchannel interactions are more important than the intrachannel interaction and relativity for obtaining high precision results.

    Full Text Available Abstract Background We compare traditional knowledge and use of wild edible plants in six rural regions of the northwest of the Iberian Peninsula as follows: Campoo, Picos de Europa, Piloña, Sanabria and Caurel in Spain and Parque Natural de Montesinho in Portugal. Methods Data on the use of 97 species were collected through informed consent semi-structured interviews with local informants. A semi-quantitative approach was used to document the relative importance of each species and to indicate differences in selection criteria for consuming wild food species in the regions studied. Results and discussion The most significant species include many wild berries and nuts (e.g. Castanea sativa, Rubus ulmifolius, Fragaria vesca and the most popular species in each food-category (e.g. fruits or herbs used to prepare liqueurs such as Prunus spinosa, vegetables such as Rumex acetosa, condiments such as Origanum vulgare, or plants used to prepare herbal teas such as Chamaemelum nobile. The most important species in the study area as a whole are consumed at five or all six of the survey sites. Conclusion Social, economic and cultural factors, such as poor communications, fads and direct contact with nature in everyday life should be taken into account in determining why some wild foods and traditional vegetables have been consumed, but others not. They may be even more important than biological factors such as richness and abundance of wild edible flora. Although most are no longer consumed, demand is growing for those regarded as local specialties that reflect regional identity.

    Objective: To study the significance of CD44 and CD54 expression in animal models with liver metastasis of colorectal cancer and try to find a stable biological marker for the early diagnosis of liver metastasis of colorectal cancer. Methods: Fourth two nude mice of 4-6 wks were adopted in the study. Thirty-six were used to establish animal models with liver metastasis of colorectal cancer, the rest 6 mice were used as the controls. 36 mice of the experimental group were divided into 6 subgroups, each containing 6 mice, in which low grade colorectal adenocarcinoma cells were injected in the subcapsule of the spleen. On the day 10th, 15th, 20th, 25th, 30th day and at the time of the brink of death, animas in each subgroup were sacrificed by eyeball removal and blood letting. Serum CD44, CD54 and CEA levels of the nude mice were measured by ELISA and the sizes and number of liver metastatic loci were observed and noted. the 6 mice for control were raised in the same cages and were killed on the 30th day, and were compared with that in the experimental group. Results: Through the measurement at different phrases, authors found with the development progression and metastasis of cancer, CD44 and CD54 levels in the animal serum tend to increase gradually and were correlated positively with the growth time, size, and extent metastasis of the cancer. Conclusion: CD44 and CD54 may be early tumor markers for liver metastasis of colorectal cancer

    The JewelPUMP™ (JP) is a new patch pump based on a microelectromechanical system that operates without any plunger. The study aimed to evaluate the infusion accuracy of the JP in vitro and in vivo. For the in vitro studies, commercially available pumps meeting the ISO standard were compared to the JP: the MiniMed® Paradigm® 712 (MP), Accu-Chek® Combo (AC), OmniPod® (OP), Animas® Vibe™ (AN). Pump accuracy was measured over 24 hours using a continuous microweighing method, at 0.1 and 1 IU/h basal rates. The occlusion alarm threshold was measured after a catheter occlusion. The JP, filled with physiological serum, was then tested in 13 patients with type 1 diabetes simultaneously with their own pump for 2 days. The weight difference was used to calculate the infused insulin volume. The JP showed reduced absolute median error rate in vitro over a 15-minute observation window compared to other pumps (1 IU/h): ±1.02% (JP) vs ±1.60% (AN), ±1.66% (AC), ±2.22% (MP), and ±4.63% (OP), P pumps: 21 (19; 25) minutes vs 90 (85; 95), 58 (42; 74), and 143 (132; 218) minutes (AN, AC, MP), P pumps (-2.2 ± 5.6% vs -0.37 ± 4.0%, P = .25). The JP was found to be easier to wear than conventional pumps. The JP is more precise over a short time period, more sensitive to catheter occlusion, well accepted by patients, and consequently, of potential interest for a closed-loop insulin delivery system. © 2014 Diabetes Technology Society.

    Full Text Available Physicochemical properties like density, viscosity, boiling point, saponification value (SV, iodine value (IV,and peroxide value (PV of Corn and Mustard oils were studied to evaluate the compositional quality of oils and also to investigate the effect on the use of same oil for repeated frying as it ultimately changes the physicochemical, nutritional and sensory properties of the oil. FT-IR spectroscopy was used to evaluate the degree of oxidation after heating and frying processes. Results revealed that due to the temperature change in the oil there is a notable difference in the spectral band which showed that the proportions of the fatty acids were changed. The spectra of Corn oil at the boiling point and at multiple frying times with a piece of potato showed frequencies in range of 2852.7–2926.0 cm−1 while in Mustard oil an additional peak was observed at 3633.8 cm−1 which exhibits the secondary oxidized product formation.

    Full Text Available Historical Research into the Nobility during the Late Mediaeval and Early Modern Period in Belgium and the Netherlands: A SnapshotThis introduction to a special issue on the history of the nobility in the Netherlands and Belgium gives a ‘snap-shot’ of the subject in two different ways. On the one hand, the collected essays demonstrate the state-of-the-art in the research carried out in 2008 on the nobility, on the other, they focus on the mediaeval and early modern periods. The major themes and problems of this historiographical tradition are evoked, emerging from the study outlined in another special issue of a historical journal, the Tijdschrift voor Geschiedenis of 1980, which looked at perspectives for future research. This introduction mainly examines the methods used by historians to confront inevitable questions such as: ‘What exactly is the nobility?’ and ‘How can this historical phenomenon be situated within processes and historical movements such as economic structures and conjunctures, social mobility and political centralization and decentralization?’

    We examine magnetic glass-coated microwires used for magnetic sensors. Images of domain structures and magnetization reversal were obtained with magneto-optical Kerr microscopy. Of particular importance were temperature-induced transformations of surface magnetic structures. Different surface magnetic domains coexist, characterized by various domain periods, magnetization directions, and nobilities of domain walls. - Highlights: • Temperature induced transformation of the domain structure in the microwires. • Co-existence of two magnetic structures differing in period and mobility of domain walls. • Short review of the basic domain structures in microwire.

    The concept of producing energy from hot dry rock (HDR), originally proposed in 1971 at the Los Alamos National Laboratory, contemplated the generation of electric power by injecting water into artificially created fractures in subsurface rock formations with high heat flow. Recognizing the inherent difficulties associated with HDR, the concept of Enhanced Geothermal Systems was proposed. This embraces the idea that the amount of permeability and fluid in geothermal resources varies across a spectrum, with HDR at one end, and conventional hydrothermal systems at the other. This report provides a concept for development of a ''Combined Technologies Project'' with construction and operation of a 6 MW (net) binary-cycle geothermal power plant that uses both the intermediate-depth hydrothermal system at 1,200 to 3,300 feet and a deeper EGS capable system at 3,000 to 4,000 feet. Two production/injection well pairs will be drilled, one couplet for the hydrothermal system, and one for the E GS system. High-pressure injection may be required to drive fluid through the EGS reservoir from the injection to the production well.

Empleando suspensiones de las cepas animalizadas se inocularon intranasalmente cuatro chinchillas, y solo a dos de ellas se le inoculo una mezcla de las bacterias comensales (Streptococcus mitis, Streptococcus parasanguinis. Con un otoscopio se examinó la evolución de la infección a los 7 y 14 días. Se sacrificaron los animales y se tomaron muestras de los oídos para un examen histológico. Resultados: Mediante otoscopia, se observó al día 14 que todos presentaron una membrana timpánica hiperémica sin efusión, presentándose con mayor intensidad en aquellos que recibieron el tratamiento. La histología confirmó que la administración del tratamiento no evitó que la infección evolucionara, advirtiéndose que las infectadas con el serotipo 8A y tratadas fueron las que presentaron el tejido epitelial menos comprometido respecto al resto. Conclusiones: Spn y las bacterias comensales podrían establecer una relación competitiva, y el efecto moderador en la progresión de la infección de otitis media dependería del serotipo involucrado.

    Investigations within the Silverton caldera, in southwestern Colorado, used a combination of traditional geological mapping, alteration-assemblage mapping, and aqueous geochemical sampling that showed a relationship between geological and hydrologic features that may be used to better understand the provenance and evolution of the water. Veins containing fluorite, huebnerite, and elevated molybdenum concentrations are temporally and perhaps genetically associated with the emplacement of high-silica rhyolite intrusions. Both the rhyolites and the fluorite-bearing veins produce waters containing elevated concentrations of F-, K and Be. The identification of water samples with elevated F/Cl molar ratios (> 10) has also aided in the location of water draining F-rich sources, even after these waters have been diluted substantially. These unique aqueous geochemical signatures can be used to relate water chemistry to key geological features and mineralized source areas. Two examples that illustrate this relationship are: (1) surface-water samples containing elevated F-concentrations (> 1.8 mg/l) that closely bracket the extent of several small high-silica rhyolite intrusions; and (2) water samples containing elevated concentrations of F-(> 1.8 mg/ l) that spatially relate to mines or areas that contain late-stage fluorite/huebnerite veins. In two additional cases, the existence of high F-concentrations in water can be used to: (1) infer interaction of the water with mine waste derived from systems known to contain the fluorite/huebnerite association; and (2) relate changes in water quality over time at a high elevation mine tunnel to plugging of a lower elevation mine tunnel and the subsequent rise of the water table into mineralized areas containing fluorite/huebnerite veining. Thus, the unique geochemical signature of the water produced from fluorite veins indicates the location of high-silica rhyolites, mines, and mine waste containing the veins. Existence of high F-concentrations along with K and Be in water in combination with other geological evidence may be used to better understand the provenance of the water. ?? 2009 AAG/Geological Society of London.

    Full Text Available The outbreak of the jungle or forest yellow fever, through the adapta¬tion, quite recently of the yellow fever virus o the forest mosquitoes, brou¬ght the necessity of ecological researches on hese mosquitoes, as well as on the wild animals they bite, some of them being susceptible to the desease. This has been done by the special yellow fever Service of the State of Sao Paulo, in a special Biological Station in Perús, São Paulo, which has been built in the midst of the jungle. This station was made with plain materials, and covered with straw, but was confortable enough for the technical work, i nthe early months of 1938. During the months in which the investigations were being carried on, the following interesting results were obtained: 1. As we have already pointed out in other places, the forest mosquitoes biting us during daytime, are always new born insects, having not yet sucked blood, as it is the general rule with all mosquitoes, and therefore also, with the anopheles and stegomyia, and this explains why nobody gets malaria or yellow fever, transmitted by anofeles or by aedes aegypti during the day. We think therefore, the jungle yellow fever, got during daytime is not due to the infected jungle or forest mosquito biting, but to infection through the human skin coming into close contact with tre virus, which the forest mosquitoes lay with their dejections, on the leaves of the trees where they remain sitting du¬ring the day. 2. As it is the rule with anopheles, stegomyia and other mosquitoes, the insects once having sucked blood, take nocturnal habits and, therefore, bite us, only during the night, so it happens with the forest mosquito, and insects with developped eggs and blood in stomach have been caught within the sta¬tion house, during the night. During the day, these mosquitoes do not bite, but remain quite still on the leaves of the trees, in the damp parts of the woods. 3. Jungle or forest mosquitoes can easely bite wild animals, some with more avidity then ethers, as it has bee npointed out to the opossum (didei-phis and other animals. They also bite birds having very thin skin and only exceptionally, cold bloods animals. 5. Is has hot been possible to ascertain how forest mosquitoes are able to live, from onde season to another, through winter, when temperature drops near and even below zero. They have not been found in holes of the terrain, of trees and of animals, as it is the rule in cold countries. During winter, in the forest, it is possible to find larvs in the holes of bambus and trees full of water. As wild animals do not harbour the yellow fever virus for a long time in their body, it is diffcult to explain how the desease lasts from one season to another. Many ecological features on the mosquito, remains yet to be explained and therefore it in necessary to go on with the investigations, in bio¬logical stations, such as that one built up in Perús, São Paulo.

    Full Text Available The autobiography of romantic creation is manifested through the correlation ”dream – art” and less through the traditional ”life – art”. The artist of this spiritual texture, is however, impelled from the inside not to evoke the immediate reality, but the effervescence of the dreams and the splendours of imagination, so to transmigrate to his lyrical hero only his heroic, altruistic, and great aspirations. The predominance in the film director’s records of the heroine’s character, not of the hero’s, through the weight of confessional valences, is reinforced by the master’s persistence, even his obsession with the singing of the myth of the eternal feminine in the most varied versions and interpretations. Appealing to the ”psychology of the depths”, the following phenomenon has been stated: in the equation of the protagonists of Loteanu’s works, the power of character, courage, even possessiveness are more decisive in feminine characters, the masculine ones yielding to the vigour and vitality of their loved ones. On the other hand, the lyrical heroes are characterized by the spiritual states associated with the beautiful sex for centuries: dreamers, sensitive, always subject to turmoil and anxiety. This anthropological distortion explains the situation of the Woman in the major hypostasis of Axis Mundi, and of the man in that of the wandering son, who has forgotten his role. In Emil Loteanu’s cinematography, the nostalgia of the paradisiac myth of the androgyne is countered by empowering the lyrical heroines with the functions of protecting and saving the world, they are the ones recovering the cracks of their second halves.

    ătre Adunarea Deputaţilor Nobilimii din Podolia lipsesc actele care ar adeveri că Adronache Cernelevski a deţinut rangul de paharnic, precum şi faptul că solicitanţii nominalizaţi sunt urmaşi direcţi ai acestuia. În situaţia creată membrii familiei Cernelevski cer să fie acceptaţi în categoria odnodvorţilor din Basarabia. Astfel, odată cu infiltrarea persoanelor alogene în rândurile nobilimii basarabene, s-a produs schimbarea componenţei etnice, rusificarea şi deznaţionalizarea acestei categorii sociale.THE ASSIMILATION OF POLISH NOBILITY AMONG BESSARABIAN NOBILITY DURING XIXth CENTURY. (Case study: noble family Celinski and Cernilev/Cernelevski In the article, based on archive documents and published monographic studies, to treat the problem of assimilation of allergenic nobles by Bessarabian nobility, having as example the polish nobles. Being strategically, located Bessarabia was of particular interest in expansion policy of the Russian Empire. For these reasons, once the territory annexed, the tsarist searched to create a social base here to support and promote imperial policy. Besides granting various privileges to the native population, especially to the nobility, the imperial administration directed an intense colonization policy of the territory between Dniester and Prut and infiltration of Russian nobles or just simple clerks of Russian origin, coming from different parts such as Poland, Austria etc. among native nobility. As a result, during the XIXth century, alongside with local boyars in the confirmation of titles of nobility, at the commission created to this purpose, were registered representatives of allergenic nobility. Analysis of the files submitted by polish nobility revealed that their noble titles were confirmed after the presentation of a certificate certifying the applicant's noble affiliation by Assembly of Deputies of nobility from Podolia. There are as well cases of refusal of confirmation of titles to the polish nobility. After

    This study investigated the fumigant toxicity of 4 Asteraceae plant essential oils and their constituents against the Japanese termite Reticulitermes speratus Kolbe. Fumigant toxicity varied with plant essential oils or constituents, exposure time, and concentration. Among the tested essential oils, those from Chamaemelum nobile exhibited the strongest fumigant toxicity, followed by those from Santolina chamaecyparissus, Ormenis multicaulis, and Eriocephalus punctulatus at 2 days after treatment. In all, 15, 24, 19, and 9 compounds were identified in the essential oils from C. nobile, E. punctulatus, O. multicaulis, and S. chamaecyparissus, respectively, by using gas chromatography, gas chromatography-mass spectrometry, or open-column chromatography. The identified compounds were tested individually for their fumigant toxicity against Japanese termites. Among the test compounds, trans-pinocarveol, caryophyllene oxide, sabinene hydrate, and santolina alcohol showed strong fumigant toxicity against Japanese termites. Acetylcholinesterase (AChE) inhibition activity of the identified compounds from C. nobile, E. punctulatus, O. multicaulis, and S. chamaecyparissus essential oils were tested to determine the mode of their action. The IC50 values of (+)-α-pinene, (-)-limonene, (-)-α-pinene, β-pinene, and β-phellandrene against Japanese termite AChE were 0.03, 0.13, 0.41, 0.42, and 0.67mg/mL, respectively. Further studies are warranted to determine the potential of these essential oils and their constituents as fumigants for termite control. Copyright © 2014 Elsevier Inc. All rights reserved.

    2012-10-01

    Full Text Available The documents known as Ragman Roll collect the fealty oaths sworn and the homages rendered by Scottish nobility, clergy, landowners and burgesses to Edward I Plantagenet after the English invasion of Scotland in the spring and summer of 1296. These documents record personal names and surnames of ca. 1800 people, being a precious source for the study of Scottish anthroponymy in the second half of the 13th century. This paper focuses on the feminine anthroponyms occurring in the Ragman Roll, on their form and on their historical-etymological and cultural background.

    Full Text Available Archetype Theory, has been raised from Carl Gustav Young’s Psychoanalytical School. Young knows mental images and Sediments and Hereditary information which there are in the collective unconscious as Archetype. In other word, archetype is general type of repeated experiences and behaviors of human forefathers which rooted in collective unconscious. the most important Archetypes are "Anima"," Animus", "old wise man", "shadow", "mask", "rebirth" ,and "self" and "individuality". Kalila va Demna is the book which is full of allegorical stories, which because of their mythical aspect, are researchable from Archetypal Analytic criticism. One of this stories which Archetypal color is Dominant in it, is "Almalek and Albrahmh” from 16th chapter of Kalila va Demna. In this study, some archetypes such as "shadow", "Anima", "mask", "old wise man", " self " and "individuality" in the story of "Almalek and Albrahmh" from sixteenth chapter of book, has been analyzed. Since either this tale because of being legendary, and consisting of series of dreams – which have given it mythical, symbolic and interpretable nature – has capacity for archetypal analysis, or archetypal approach has high capacity and power to analyze such narrations. The story was investigated on mentioned view, and it was found that king Heblar which has stricken to a kind of Psychosis, Finds its way into the subconscious through dreams and After a confrontation with his anima, under guidance of old wise meets his self (true self and reach to his individuality and Is rescued from distress. It can be said that the king starts his path of the individual process with a dream.  He, in the bigining of the story, with the help of Iran Dokht and at the end of the story, with the help of minister is released of grief and psychosis.

    The acidic discharge from Cement Creek, containing elevated concentrations of dissolved metals and sulphate, mixed with the circumneutral-pH Animas River over a several hundred metre reach (mixing zone) near Silverton, CO, during this study. Differences in concentrations of Ca, Mg, Si, Sr, and SO42- between the creek and the river were sufficiently large for these analytes to be used as natural tracers in the mixing zone. In addition, a sodium chloride (NaCl) tracer was injected into Cement Creek, which provided a Cl- 'reference' tracer in the mixing zone. Conservative transport of the dissolved metals and sulphate through the mixing zone was verified by mass balances and by linear mixing plots relative to the injected reference tracer. At each of seven sites in the mixing zone, five samples were collected at evenly spaced increments of the observed across-channel gradients, as determined by specific conductance. This created sets of samples that adequately covered the ranges of mixtures (mixing ratios, in terms of the fraction of Animas River water, %AR). Concentrations measured in each mixing zone sample and in the upstream Animas River and Cement Creek were used to compute %AR for the reference and natural tracers. Values of %AR from natural tracers generally showed good agreement with values from the reference tracer, but variability in discharge and end-member concentrations and analytical errors contributed to unexpected outlier values for both injected and natural tracers. The median value (MV) %AR (calculated from all of the tracers) reduced scatter in the mixing plots for the dissolved metals, indicating that the MV estimate reduced the effects of various potential errors that could affect any tracer.

    Full Text Available This article studies the role of the nobility in the XV century military expansion of the Crown of Aragon, through the particular case of the valencian nobility and the Alphonse V the Magnanimous's war cycle betwen the years 1420 and 1448. If s first analyzed the development of the royal campaigns. Then, the Valencian lineages are identified, also precising their particular degree of involvement in the royal wars. The study is based upon the registers of the Royal Treasury and Cancillery, supplemented by notarial and judicial records, and the chronicles. The militarization of the nobility was unequal. The majority of the noblemen were involved occasionally in the royal wars, more as an social obligation than a professional committment. The professionalization only attained a minority of lineages, attached to the royal household: they constituted the military king´s affinity, most of them coming from the low urban nobility —most of them also being youngers sons, bastards or belonging to secondary branches.

    Full Text Available Ragusan wills of 13th and 14th centuries reveal peculiar and unsuspected aspects about armed pilgrimages by proxy in the Balkans. The struggle against infedeles and heretics propagandized by the Roman Church finds financial support and full agreement in Dubrovnik citizens, also thanks to the Franciscan and Dominican preaching. Nobles, merchants, clerics and priests, craftsmen, men and women, they are all ready to take part in the Just war. Anyway they would fight only on the condition of leaving a sum of money to those who would fight for their souls’ salvation.

    I testamenti ragusei del XIII e XIV secolo rivelano aspetti particolari e per nulla indagati sul pellegrinaggio armato per procura in area balcanica. La lotta agli infedeles e agli eretici messa in atto dalla Chiesa di Roma trova sostegno economico e piena adesione nei cittadini di Dubrovnik, città-stato baluardo della cristianità più a levante, anche grazie alla campagna pubblicistica attuata da francescani e domenicani. Nobili, mercanti, chierici e preti, artigiani, uomini e donne partecipano alla giusta guerra, prevedendo lasciti per uomini che combatteranno per la salvezza delle anime dei testatori.

  9. Consuming Social Networks: A Study on BeeTalk Network

    Directory of Open Access Journals (Sweden)

    Jamal Mohammadi

    Full Text Available BeeTalk is one of the most common social networks that have attracted many users during these years. As a whole, social networks are parts of everyday life nowadays and, especially among the new generation, have caused some basic alterations in the field of identity-formation, sense-making and the form and content of communication. This article is a research about BeeTalk users, their virtual interactions and experiences, and the feelings, pleasures, meanings and attitudes that they obtain through participating in the virtual world. This is a qualitative research. The sample is selected by way of theoretical sampling among the students of University of Kurdistan. Direct observation and semistructured interviews are used to gathering data, which are interpreted through grounded theory. The findings show that some contexts like “searching real interests in a non-real world” and “the representation of users’ voices in virtual space” have provided the space for participating in BeeTalk, and an intervening factor called “instant availability” has intensified this participation. Users’ participation in this social network has changed their social interaction in the real world and formed some new types of communication among them such as “representation of faked identities”, “experiencing ceremonial space” and “artificial literacy”. Moreover, this participation has some consequences like “virtual addiction” and “virtual collectivism” in users’ everyday life that effects their ways of providing meaning and identity in their social lives. It can be said that the result of user’s activity in this network is to begin a kind of simulated relation that has basic differences with relations in the real world. The experience of relation in this network lacks nobility, enrichment and animation, rather it is instant, artificial and without any potential to vitalization.

  10. Reducing Structural Violence through Entrepreneurial Tourism: Case Study in Hambantota District, Sri Lanka

    Directory of Open Access Journals (Sweden)

    Shammika DLAH

    2014-01-01

    Full Text Available Tourism is increasingly recognized as an effective means of achieving peace in world. In this paper tourism’s contribution for peace will be discussed in a broader sense with identification of structural violence as the main cause of Sri Lankan conflict. Structural violence is the process of deprivation of needs. It is characterized politically as repression, and economically by exploitation. The methodology used in this paper to identify ‘how entrepreneurial tourism can contribute to alleviate structural violence’ was basically qualitative. The methodology was based on the grounded theory which portrays the world as being complex and organized by both overt and hidden power structures. It was revealed during the process of data collection that the structural violence was functioning by means of polarization of the social structures such as caste, ethnicity, economic status, nobility, educational status into different strata together with grouping of people into the consequential ends leading to social uneasiness. People engaged in entrepreneurial activities are entrapped in a viscous system of unfair resource allocation and production exploitation operating through intermediaries. The paper suggests that it is necessary to seek remedies to increase the capacity of entrepreneurs to overcome the destructive force of the structural violence.

    A study was made of the geological, geochemical and geophysical characteristics of potential geothermal areas in the Rio Grande rift and Basin and Range province of New Mexico. Both regional and site-specific information is presented. Data was collected by: (1) reconnaissance and detailed geologic mapping, emphasizing Neogene stratigraphy and structure; (2) petrologic studies of Neogene igneous rocks; (3) radiometric age-dating; (4) geochemical surveying, including regional and site-specific water chemistry, stable isotopic analyses of thermal waters, whole-rock and mineral isotopic studies, and whole-rock chemical analyses; and (5) detailed geophysical surveys, using electrical, gravity and magnetic techniques, with electrical resistivity playing a major role. Regional geochemical water studies were conducted for the whole state. Integrated site-specific studies included the Animas Valley, Las Cruces area (Radium Springs and Las Alturas Estates), Truth or Consequences region, the Albuquerque basin, the San Ysidro area, and the Abiquiu-Ojo Caliente region. The Animas Valley and Las Cruces areas have the most significant geothermal potential of the areas studied. The Truth or Consequences and Albuquerque areas need further study. The San Ysidro and Abiquiu-Ojo Caliente regions have less significant geothermal potential. 78 figs., 16 tabs.

  12. Hydrology of coal-lease areas near Durango, Colorado

    Brooks, Tom

    1985-01-01

    The U.S. Bureau of Land Management leases Federal lands and minerals for coal mining near Durango, Colorado. This report addresses the hydrologic suitability of those lands for coal leasing; the report describes the general hydrology of the Durango area and, more specifically, the hydrology of the Stollsteimer Creek study area 32 miles east of the Durango and the Hay Gulch study area, 12 miles southwest of Durango. The most productive aquifers in the Durango study area are Quaternary alluvium and the tertiary Animas Formation. Water wells completed in alluvium typically yield 5 to 20 gallons/min; wells completed is the Animas Formation yield as much as 50 gallons/min. Water quality in these aquifers is variable, but it generally is suitable for domestic use. The coal-bearing Cretaceous Fruitland and Menefee Formations are mined by surface methods at the Chimney Rock Mine in the Stollsteimer Creek study area and by underground methods at the National King Coal Mine in the Hay Gulch study area. Effects of surface mining in the Stollsteimer Creek area are: (1) Dewatering of an alluvial aquifer; and (2) Local degradation of alluvium water quality by spoil-pile effluent. Effects of underground mining in the Hay Gulch area are: (1) Introduction of water with greater dissolved-solids concentrations into the upper Hay Gulch alluvium from mine runoff; (2) Subsidence fracturing which could dewater streams and the alluvial aquifer.

    The spatial and temporal distribution of selected physical and chemical surface-water-quality characteristics were analyzed at stream sites throughout the Dolores and San Juan River Basins in southwestern Colorado using historical data collected from 1990 through 2005 by various local, State, Tribal, and Federal agencies. Overall, streams throughout the study area were well oxygenated. Values of pH generally were near neutral to slightly alkaline throughout most of the study area with the exception of the upper Animas River Basin near Silverton where acidic conditions existed at some sites because of hydrothermal alteration and(or) historical mining. The highest concentrations of dissolved aluminum, total recoverable iron, dissolved lead, and dissolved zinc were measured at sites located in the upper Animas River Basin. Thirty-two sites throughout the study area had at least one measured concentration of total mercury that exceeded the State chronic aquatic-life criterion of 0.01 μg/L. Concentrations of dissolved selenium at some sites exceeded the State chronic water-quality standard of 4.6 μg/L. Total ammonia, nitrate, nitrite, and total phosphorus concentrations generally were low throughout the study area. Overall, results from the trend analyses indicated improvement in water-quality conditions as a result of operation of the Paradox Valley Unit in the Dolores River Basin and irrigation and water-delivery system improvements made in the McElmo Creek Basin (Lower San Juan River Basin) and Mancos River Valley (Upper San Juan River Basin).

    The electrode potential or galvanic series is usually used to reflect the nobility of metals and semi-metals. However, this potential is environment-dependent and the intrinsic nobility of a metal is ultimately governed by its electron stability, which can be represented by the electron work function (EWF). This article reports our studies on the corrosion behavior of isomorphous Cu–Ni alloy in HCl and NaCl solutions, respectively. It was demonstrated that the EWF of the alloy increased as the Ni concentration was increased, so did the corrosion resistance in the acidic solution. In the sodium chloride solution, however, the trend was reversed due to adsorption, hydrolysis and the formation of oxide scale on Cu-rich samples, which more or less prevented them from further corrosion in this solution. In order to confirm this, corrosive wear tests were performed to analyze the performance of the alloy when the effect of oxide scale was eliminated or minimized by the mechanical action. - Highlights: • Increasing %Ni resulted in higher overall electron work function of Cu–Ni alloy. • Higher EWF corresponded to higher resistance to corrosion in a HCl solution. • Trend was reversed in a NaCl solution due to the formation of oxide scale. • During slurry-jet tests, alloys with higher EWFs performed better.

    Highlights: • Enrichment of Ti/Zr (as TiO 2 /ZrO 2 ) and depletion of Cu/Ni due to thermodynamically driven segregation. • Dominant corrosion mechanism is pitting. • Pit interiors were depleted of Ti and Zr due to equilibrium solubilization of oxide layer. • Corrosion can be explained by equilibrium and metal nobility arguments. - Abstract: The corrosion resistance of oxides that form in air on Vitreloy 101 (Cu 47 Ti 34 Zr 11 Ni 8 ) metallic glass ribbons in NaCl and HCl solutions was studied by scanning electron microscopy, X-ray photoelectron spectroscopy and potentiodynamic polarization. The air-exposed alloy was covered by a TiO 2 /ZrO 2 layer overlying a Cu-enriched region beneath. Ni was absent at the surface. Segregation of Ti and Zr was driven by exothermic oxide formation. Immersion in NaCl or HCl caused pitting corrosion by local Galvanic reactions that depleted less noble Ti, Zr and Ni from the pit interiors, leaving them rich in more noble Cu. Corrosion products containing Ti and Zr accumulated around the pit. Pits were most numerous in 1.0 M HCl due to TiO 2 (s)/Ti 3+ (aq) equilibrium that resulted in rapid solubilization of the oxide, creating local weaknesses and an increased rate of pit formation. On average, Ti preferentially dissolved from the oxide in accord with metal nobility arguments

    The electrode potential or galvanic series is usually used to reflect the nobility of metals and semi-metals. However, this potential is environment-dependent and the intrinsic nobility of a metal is ultimately governed by its electron stability, which can be represented by the electron work function (EWF). This article reports our studies on the corrosion behavior of isomorphous Cu–Ni alloy in HCl and NaCl solutions, respectively. It was demonstrated that the EWF of the alloy increased as the Ni concentration was increased, so did the corrosion resistance in the acidic solution. In the sodium chloride solution, however, the trend was reversed due to adsorption, hydrolysis and the formation of oxide scale on Cu-rich samples, which more or less prevented them from further corrosion in this solution. In order to confirm this, corrosive wear tests were performed to analyze the performance of the alloy when the effect of oxide scale was eliminated or minimized by the mechanical action. - Highlights: • Increasing %Ni resulted in higher overall electron work function of Cu–Ni alloy. • Higher EWF corresponded to higher resistance to corrosion in a HCl solution. • Trend was reversed in a NaCl solution due to the formation of oxide scale. • During slurry-jet tests, alloys with higher EWFs performed better.

    Full Text Available This paper analyzes the process of changing local laws (fueros to a territorial law (fuero in the context of the new kingdom of Valencia created in 1240 by King James I. Following the tradition of Catalonia and Aragon, also in Valencia the crown and nobility initially organized the repopulation based on different local fueros: Sepúlveda, Zaragoza, Daroca, Teruel, Fontana, costum de Lleida or costum/fuero of Valencia. But from 1245, the monarchy drove the territorial law (fuero of Valencia, which has traditionally been interpreted as a political reason for confrontation between Catalan and Aragonese populators. Our study explains how the Fuero of Zaragoza/Aragon was limited during the 13th Century to a few seigneuries, and how widespread the Fuero of Valencia. Thus, the conflict between the nobility of Aragonese origin to the public power (monarchy and citizens began when the first courts of 1261 approved extending the Fuero of Valencia as a territorial law for the new kingdom.

    2007-11-01

    Full Text Available This article examines indicatively offences such as blasphemy, sodomy, adultery and bigamy and the penalties imposed by the Venetian authorities on the island of Crete in sixteenth century. As the sixteenth century was characterised by a strong tendency towards the moralisation of life in the states of Western Europe, State and Church focused on all forms of deviance from the Christian order: issues related to faith, individual behaviour, family life and sexuality, all became objects of discipline. The Venetian state, in collaboration with the church, also penalised offences related to Christian morality, in the island of Crete as well as elsewhere in the Venetian state. The attitude of the Venetian state towards Crete, differences between the city of Venice and the island in the administration of rules governing deviance and promoting moral standards were slight, despite the presence of a substantial Orthodox community. Although, in some offences related to family life Venetian law respected the customs of the Orthodox church. Furthermore, in some cases the treatment of Jews was stricter, as Jews were considered as a possible threat to Christianity and the social structure of the Venetian state. A more significant factor than religious difference on the treatment of these offences was class and economic status and gender. Finally, the moral discipline and strict control over aspects of community life was intended not only to promote the well-being of subjects, and therefore the administration of the state, but also the protection of the prestige, identity and financial interests of the ruling class of nobility.

    Absorption studies were once quite popular but hardly anyone does them these days. It is easier to estimate the blood level of the nutrient directly by radioimmunoassay (RIA). However, the information obtained by estimating the blood levels of the nutrients is not the same that can be obtained from the absorption studies. Absorption studies are primarily done to find out whether some of the essential nutrients are absorbed from the gut or not and if they are absorbed, to determine how much is being absorbed. In the advanced countries, these tests were mostly done to detect pernicious anaemia where vitamin B 12 is not absorbed because of the lack of the intrinsic factor in the stomach. In the tropical countries, ''malabsorption syndrome'' is quire common. In this condition, several nutrients like fat, folic acid and vitamin B 12 are not absorbed. It is possible to study absorption of these nutrients by radioisotopic absorption studies

This means that it is quite an expensive operation and it is to avoid wasting this money that a pre-feasibility study is carried out. This preliminary study should eliminate cases where the electrical system cannot absorb the capacity of a nuclear station of commercial size, where other sources of power such as hydro-electricity, gas or cheap coal would make nuclear obviously uneconomic or where no suitable sites exist. If this first rather simple survey shows that nuclear power is a credible solution to a utilities need for electricity or heat production plant, then the next stage is a full feasibility study.

    Full Text Available The study of Western countries and teaching courses on the related subjects have longstanding and established tradition at MGIMO-University. The basis of this brilliant research and teaching tradition was laid down by such academicians as E.V. Tarle and V.G. Trukhanovsky, Professor L.I. Clove, Y. Borisov, F.I. Notovitch, G.L. Rozanov. Their work in 1940-1960's at the Department of World History at MGIMO-University progressed in following directions: France studies, German studies, American studies. The work resulted in a number of monographs and textbooks on modern history and foreign policy of the studied countries and regions. The aim of the publications was dictated by the goal of the Institute - to prepare the specialists in international affairs primarily for practical work. A close relationship with the Foreign Ministry was "binding advantage" sometimes limiting researchers in choosing periods and subjects for the study. At the same time the undisputed advantage and quality of regional studies at MGIMO were strengthened by the practical relevance of research, making it a vital and interesting not only for specialists but also for students and researchers from other research centers. Another characteristic of the tradition is the analysis of foreign policy and diplomacy in a close relationship with the socio-economic and political processes. Such an integrated approach to regional geography also formed largely under the influence of institutional profile designed to train highly skilled and versatile specialists in specific countries and regions with a good knowledge of their languages, history, economics, politics, law and culture. Therefore, scientific and educational-methodical work at MGIMO-University has always relied on a wealth of empirical data and has been focused on the analysis of real-world phenomena and processes, acute problems of foreign countries.

    Full text: Security studies constitute one of the major tools for evaluating the provisions implemented at facilities to protect and control Nuclear Material against unauthorized removal. Operators use security studies to demonstrate that they are complying with objectives set by the Competent Authority to counter internal or external acts aimed at unauthorized removal of NM. The paper presents the context of security studies carried out in France. The philosophy of these studies is based on a postulated unauthorized removal of NM and the study of the behavior of the systems implemented to control and protect NM in a facility. The potential unauthorized removal of NM usually may take place in two stages. The first stage involves the sequence leading to handling of the NM. It occurs inside the physical barriers of a facility and may include action involving the documents corresponding to Material Control and Accounting systems. At this stage it is possible to limit the risk of unauthorized removal of NM by means of detection capabilities of the MC and A systems. The second stage is more specific to theft and involves removing the NM out of the physical barriers of a facility in which they are being held, notably by affecting the Physical Protection System. Operators have to study, from a quantity and time lapse point of view, the ability of the installed systems to detect unauthorized removal, as well as the possibility of tampering with the systems to mask unlawful operations. Operators have also to analyze the sequences during which NM are accessed, removed from their containment and further removed from the facility in which they are stored. At each stage in the process, the probability of detection and the time taken to carry out the above actions have to be estimated. Of course, these two types of studies complement each other. Security studies have begun, in France, for more than fifteen years. Up to now more than fifty security studies are available in the

    In May 1980 it was decided to organize an intercomparison of personal dosimeters for photon radiations. The Commission of the European Communities initiated the intercomparison by starting a pilot study in which three laboratories NPL (United Kingdom), PTB (Germany) and RIV (The Netherlands) were asked to irradiate a series of personal dosemeters from institutes, GSF (Muenchen), CEA (Fontenay-aux-Roses), CNEN (Bologna) and CEGB (Berkeley). The latter institutes are secondary standard laboratories and have a radiation protection service as well. A new aspect of this pilot study is the fact that the irradiations also take place in front of a phantom. Irradiations took place in July and August 1980. The results of 4 institutes show that the personal dosemeters are quite capable of measuring the backscattered photon components

    Full Text Available Este trabajo propone el estudio de las dotes desde una perspectiva diferente a las realizadas desde una óptica exclusivamente económica, teniendo en cuenta que la historia entendida como proceso implica nociones de mediación, causación, contradicción y organización sistemática, en ocasiones estructurante de la vida social, política, económica e intelectual. El estudio de fuentes primarias permite una aproximación tanto a las relaciones intranobiliarias centradas en estrategias familiares para la consolidación de linajes como a la política del monarca en relación con la nobleza que intenta explicar desde la historia política y social la simbiosis entre la Corona y los titulados. A pesar de la "crisis" de los patrimonios nobiliarios desde fines del siglo XVI, las dotes eran imprescindibles ante la realización de un matrimonio y esto producía muchas veces un desfasaje entre los ingresos y los gastos. El endeudamiento se cubría en estas oportunidades con préstamos o favores regios. En cualquier caso, factores ideológicos, de ordenamiento social, de poder, las hacían necesarias como mecanismo a través de los cuales se llevaba a la práctica la reproducción del sistema socialThis work proposes the study of dowries from a different perspective to those carried out from an exclusively economic optic, keeping in mind that history understood as a process implies mediation and contradiction notions and systematic organization, in occasions structuring the social, politic, economic and intellectual life.

    Full Text Available At the origin of the International Law Department were such eminent scientists, diplomats and teachers as V.N. Durdenevsky, S.B. Krylov and F.I. Kozhevnikov. International law studies in USSR and Russia during the second half of the XX century was largely shaped by the lawyers of MGIMO. They had a large influence on the education in the international law in the whole USSR, and since 1990s in Russia and other CIS countries. The prominence of the research of MGIMO international lawyers was due to the close connections with the international practice, involving international negotiations in the United Nations and other international fora, diplomatic conferences and international scientific conferences. This experience is represented in the MGIMO handbooks on international law, which are still in demand. The Faculty of International Law at MGIMO consists of seven departments: Department of International Law, Department of Private International and Comparative Law; Department of European Law; Department of Comparative Constitutional Law; Department of Administrative and Financial Law; Department of Criminal Law, Department Criminal Procedure and Criminalistics. Many Russian lawyers famous at home and abroad work at the Faculty, contributing to domestic and international law studies. In 1947 the Academy of Sciences of the USSR published "International Law" textbook which was the first textbook on the subject in USSR. S.B. Krylov and V.N. Durdenevsky were the authors and editors of the textbook. First generations of MGIMO students studied international law according to this textbook. All subsequent books on international law, published in the USSR, were based on the approach to the teaching of international law, developed in the textbook by S.B. Krylov and V.N. Durdenevsky. The first textbook of international law with the stamp of MGIMO, edited by F.I. Kozhevnikov, was published in 1964. This textbook later went through five editions in 1966, 1972

    The modern Great Divide Basin is the end product of natural forces influenced by the Green River lake system, Laramide tectonism, and intermittent volcanic events. It ranks as one of the most complex structural and stratigtaphic features within the Tertiary basins of Wyoming. Portions of the Great Divide Basin and adjoining areas in Wyoming have been investigated by applying detailed and region exploration methods to known uranium deposits located within the Red Desert portions of the basin. Geologic field investigations conducted by Bendix Field Engineering Corporaton (Bendix) were restricted to reconnaissance observations made during infrequent visits to the project area by various Bendix personnel. Locations of the most comprehensive field activities are shown in Figure II-1. The principal source fo data for geologic studies of the Red Desert project area has been information and materials furnished by industry. Several hundred holes have been drilled by various groups to delineate the uranium deposits. Results from Bendix-drilled holes at selected locations within the project area are summarized in Table II-1. Additional details and gross subsurface characteristics are illustrated in cross sections; pertinent geologic features are illustrated in plan maps. Related details of continental sedimentation that pertain to the Wyoming Basins generally, and the project area specificially, are discussed in subsections of this Geologic Studies section

    Full Text Available In the present article the concept of “raznochintsy” is to be analysed. The author concludes that the “raznochintsy” cannot be considered as a kind of specific social layer. This name is assigned to a variety of categories of the population, and only one thing combines these categories in common - the opposition to other groups, whether nobles, merchants and clergy, depending on the situation, time and place. “raznochintsy” represent the phenomenon of language and social consciousness. Understanding “raznochintsy” as educated simpletons («radical intellectuals of not-noble origin» comes from Herzen and was canonized in Soviet historiography by authority of Lenin. In this definition the emphasis was placed on the opposition to the government, no gentry origin, revolutionary democracy. In modern historiography “raznochintsy” considered as a social group, located at the junction of the main classes (nobility, clergy, townspeople and peasants. “Raznochintsy” were first of all outsiders, marginals. The very first legal mention of “raznochintsy” (1701 determined them by the method of exclusion, as those who were not under the authority of the church offi ce. In the confessional statements “raznochintsy” could refer to nobles (! and domestic peasants, farmers (not included in other categories of the rural population, craft students and merchants. “Raznochintsy” in educational system were determined by opposition to other groups of students. For secular (Moscow University, this group were the nobles. In the religious schools (Kyiv-Mohyla, Slavic-Greek-Latin Academy it was usual to determine “raznochintsy“ by contrast to natives of the clergy, so in the same number of “raznochintsy” nobles may be included.

    As part of the continuing studies of the effects of very severe reactor accidents, an effort was made to develop, test, and improve simple, effective, and inexpensive methods by which the average citizen, using only materials readily available, could protect his residence, himself, and his family from injury by toxic aerosols. The methods for protection against radioactive aerosols should be equally effective against a clandestine biological attack by terrorists. The results of the tests to date are limited to showing that spores of the harmless bacterium, bacillus globegii (BG), can be used as a simulant for the radioactive aerosols. An aerosol generator of Lauterbach type was developed which will produce an essentially monodisperse aerosol at the rate of 10 9 spores/min. Analytical techniques have been established which give reproducible results. Preliminary field tests have been conducted to check out the components of the system. Preliminary tests of protective devices, such as ordinary vacuum sweepers, have given protection factors of over 1000

    Tritium in the organic fraction of soil, separated as water by high temperature combustion, was 5 to 50 times higher in activity than water that was freeze-dried from the same samples. The 50-year dose commitment from ingestion of crops is not influenced significantly by the plutonium in the SRP environment. This plutonium is a result of more than 20 years of operating chemical separations facilities. Techniques were developed to detect as little as 0.02 pCi/m 2 of iodine-129 and 0.2 pg of technetium-99 in soil to evaluate environmental effects. A sensitive three-stage mass spectrometer was completed for use in environmental studies of transuranium elements. Results of monitoring particle size distribution of entrapped particles containing Pu-238, and Pu-239,240 are reported

    Antiparticles are a crucial ingredient of particle physics and cosmology. Almost 80 years after Dirac’s bold prediction and the subsequent discovery of the positron in 1932, antiparticles are still in the spotlight of modern physics. This lecture for non-specialists will start with a theoretical and historical introduction. Why are antiparticles needed? When and how were they discovered? Why is the (CPT) symmetry between particles and antiparticles so fundamental? What is their role in cosmology? The second part will give an overview about the many aspects of antiparticles in experimental physics: their production, their use in colliders; as a probe inside atoms or nuclei; or as an object to study fundamental symmetries. In the third part, the lecture will focus on results and challenges of the “antimatter” programme at the Antiproton Decelerator (AD), with special emphasis on antihydrogen production, trapping and precision measurements.

    This work is focused about the spectroscopic properties of a polymer material which consists of Polyacrylic acid (Paa) doped at different concentrations of Europium ions (Eu 3+ ). They show that to stay chemically joined with the polymer by a study of Nuclear Magnetic Resonance (NMR) of 1 H, 13 C and Fourier Transform Infrared Spectroscopy (Ft-IR) they present changes in the intensity of signals, just as too when this material is irradiated at λ = 394 nm. In according with the results obtained experimentally in this type of materials it can say that is possible to unify chemically the polymer with this type of cations, as well as, varying the concentration of them, since that these are distributed homogeneously inside the matrix maintaining its optical properties. These materials can be obtained more quickly and easy in solid or liquid phase and they have the best conditions for to make a quantitative analysis. (Author)

    Full Text Available The "Founding fathers" of American Studies at MGIMO are considered to be A.V. Efimov and L.I. Clove. Alexey Efimov - Corresponding Member of the USSR Academy of Sciences since 1938, Head of the Department of Modern and Contemporary History and Dean of the Historical School at the Moscow State University - one of the first professors of the Faculty of International Relations MGIMO. Efimov distinguished himself by a broad vision and scope of scientific interests. Back in 1934 he published a monograph "On the history of capitalism in the United States," which initiated a series of research culminating in the fundamental work "The United States. The path of capitalist development (pre-imperialist era". Alexey was not only a great scientist but also a great teacher, whose lectures was popular throughout Moscow. His lecture courses, given at the end of the 1940s at MGIMO, became the basis for the first post-war history textbooks USA - "Essays on the history of the United States." At least as colorful a figure was Professor Leo Izrailevich Zubok - a man of unusual destiny. As a teenager he emigrated to the United States with his parents, where he soon joined the American revolutionary movement in the 1920s and was forced to leave the country. He came to MGIMO being already an experienced scientists. His research interests were very wide: from the study of American foreign policy expansion to the history of the labor movement in the United States. Zubok's fundamental works still have not lost its scientific significance. He has successfully combined scientific work with teaching. Tutorials that are based on his lectures were very popular not only among students of MGIMO.

    Thermal stress to microorganisms was measured by the production of dissolved organic matter by algal communities and the mineralization of glucose by heterotrophic populations. Mutagenic activity as measured by the Ames/Salmonella/microsome assay indicate that such activity does not occur in Par Pond, although limited mutagenic activity does occur in a nearby canal system due to chlorination of cooling water. Sodium hypochlorite, used as an algicide in the reactor fuel storage basins, caused increased pitting corrosion to reactor fuel targets. Five other compounds selected for testing proved to be superior to sodium hypochlorite. Legionella pneumophila, the pathogen which causes Legionnaire's disease, was found to be a natural part of aquatic ecosystems. It occurs over a wide range of environments and is able to utilize nutrients provided by primary producers. Phytoplankton size classes of less than 3 μm (less than 5% of the total phytoplankton biomass) accounted for 15 to 40% of the total primary productivity in Par Pond, Pond C, and Clark Hill Reservoir. Three major biological data sets were compiled and are available in the SRL computer system for analysis: the SRP deer herd data; 20 years of Par Pond data; and 25 years of biological data on the Savannah River. Results of marine studies indicated that nearly all plutonium in the Savannah River and its estuary resulted from nuclear weapons fallout. The plutonium concentration in the Savannah River is about one fourth the concentration in the Newport River which has no nuclear operations associated with it

    The New Research Initiatives Program (NRIP) project on catalysis in Los Alamos Scientific Laboratory (LASL) Group CMB-8 has made significant progress towards performing the first basic in situ experimental studies of heterogeneous catalysis on solid compound surfaces in a LEED-Auger system. To further understand the surface crystallography of a possible catalyst compound, LEED-Auger measurements were made on UO 2 (approximately 100) vicinal surfaces. These (approximately 100) vicinal surfaces were shown to decompose irreversibly into lower index facets, including prominent (100) facets, at temperatures below those needed for creation of lowest index faceting on (approximately 111) vicinal surfaces. LEED examination of fully faceted surfaces from both types of UO 2 vicinal cuts did not show evidence of cyclopropane or propene chemisorption. The existing LEED-Auger system was modified to allow catalytic reactions at approximately less than 10 -3 torr. A sample holder, specifically designed for catalysis measurements in the modified system, was tested while examining single crystals of CoO and Cr 2 O 3 . Extensive LEED-Auger measurements were made on CoO in vacuo and in the presence of light hydrocarbons and alcohols plus H 2 O, NO, and NH 3 . No chemisorptive behavior was observed except with H 2 O in the presence of the electron beam. Although only examined briefly, the Cr 2 O 3 was remarkable for the sharp LEED features obtained prior to any surface treatment in the vacuum system

    Full Text Available This paper analyzes the social strategies used by some Spaniards in Peru during the eighteenth century. After achieving a certain amount of prosperity through business or by holding positions in the administration, these individuals pursued acceptance and recognition from their neighbors, an aim that necessarily led to integration. Marrying Creole women, obtaining all kinds of honorary positions along with ennoblement and post mortem legacies and foundations were some of the strategies used. The choice of a group of candidates for a position of nobility as the study sample provides a model of the social practices adopted by these groups, which were growing and fighting for their place in Peruvian society.

    2014-01-01

    Full Text Available This paper discusses the tragic life of Faulkner’s Emily Grierson, a life dominated by patriarchy and traditional Southern social values, which concludes with her living as a lonely recluse in her family’s decaying aristocratic house for more than forty years until her death. The key of the tragedy is her father, who isolates Emily from the outside world and tortures her with traditional patriarchal rules and Southern family duty. Emily is expected to lead a life like other girls; however, under the burden of old-fashioned, patriarchal responsibilities, her inner world collapses. This study uses the Jungian concepts of archetypes, persona and shadow, anima and animus to interpret Emily’s transitions and her fall. By examining the process through the lens of Jungian theories, the aspects that affect her fall in the patriarchal, aristocratic society, as well as the inherited social values, can be revealed and specified

    Full Text Available This article contains a review of the monograph by Yu.V. Seleznev published in early 2017 and dedicated to the relations of Russian princes with the Golden Horde’s khans and their status among the Golden Horde’s nobility. This work is the first comprehensive study in the historiography of this issue for all two and a half centuries of the Tartar domination. The monograph was published for the first time in 2013 and served as the basis for a doctoral dissertation, which Seleznev defended in 2015. The book was reprinted with certain changes in 2017. The book commendably contains an abundance of factual material through the use of diverse sources and strands of historiography. Seleznev examines the social terminology of Golden Horde-Russian relations, the structure of the Golden Horde’s nobility and the trips of princes to the Horde, drawing attention not only to the status of the great Vladimir and Moscow princes, but also that of other great and appanage princes. He makes a significant contribution to the resolving the debate regarding the nature of the Golden Horde’s domination in Rus’ by examining in detail the relationship of the Russian princes with the Golden Horde’s authorities in different years. The book’s author proposed to divide the Golden Horde’s “yoke” into seven periods characterized by “changes in the degree of sovereignty and jurisdiction of the khan in relation to Russian principalities”. The author of this review agrees with the main conclusions of the book under review, but at the same time he notes some reservations and criticisms, which do not, however, reduce the academic caliber of the monograph.

    2014-01-01

    Full Text Available Background: Although several studies have been done on lip prints for human identification in forensic science, there is a doubt about their use in gender determination. Aims: The present study was designed to study the lip groove patterns in all the quadrants of both male and female subjects to identify the sex, based on the patterns of the grooves of the lip prints. Study Design: 300 lip prints were collected from volunteers of D. J. College of Dental Sciences and Research, Modinagar (UP. Materials and Methods: Lip prints were recorded with lip stick and transferred on to a glass slide. Statistical Analysis: Pearson chi-square test was adopted for statistical analysis and probability value (P value was calculated. Conclusion: In our study, none of the lip prints were identical, thus confirming the role of lip prints in individual identification. According to Suzuki′s classification, Type I, II, III and IV patterns were significant in gender determination.

    A preliminary sensitivity study of the salt repository design has been performed to identify critical site and design parameters to help guide future site characterization and design optimization activities. The study considered the SCP-conceptual design at the Deaf Smith County site in Texas with the horizontal waste package emplacement mode as the base case. Relative to this base case, parameter variations were compared. Limited studies were performed which considered the vertical emplacement mode geometry. The report presents the reference data base and design parameters on which the study was based (including the range of parameters that might be expected). Detailed descriptions of the numerical modeling methods and assumptions are included for the thermal, thermomechanical and hydrogeological analyses. The impacts of parameter variations on the sensitivity of the rock mass response are discussed. Recommendations are provided to help guide site characterization activities and advanced conceptual design optimization activities. 47 refs., 119 refs., 22 tabs

  1. Southeastern Cancer Study Group: breast cancer studies

    International Nuclear Information System (INIS)

    Smalley, R.V.; Bartolucci, A.A.; Moore, M.

    1983-01-01

    During the past 10 years, the Southeastern Cancer Study Group (SECSG) has been engaged in one major adjuvant study and three major advanced disease studies for patients with adenocarcinoma of the breast. The adjuvant study is demonstrating that six months of adjuvant CMF is the therapeutic equivalent of 12 months and that post-operative irradiation is of no added therapeutic benefit. In patients with advanced disease, a low dose 5 drug combination of CMFVP induces more objective responses than single agent 5FU, but improves survival only for those patients with liver metastases when compared to the sequential use of the same 5 single agents. The three drug combination, CAF, utilizing doxorubicin, induces more objective responses than low dose CMFVP, but it does not improve overall survival. The addition of a phase active combination, CAMELEON, (i.e., sequentially alternating therapy) of CAF has not improved the duration of disease control and survival for patients with liver metastases, lymphangitic and nodular lung metastases compared to CAF. Aggressive combination chemotherapeutic approaches to patients with advanced disease provide better and longer disease and tumor control but only marginal improvements in overall survival. Adding additional agents to a maximally tolerable regimen has not improved the therapeutic outcome

    2015-01-01

    Suicide is one of the leading causes of preventable deaths. Recent data suggest South India as one of the regions with highest suicide rates in the world. In 2013, 134,799 people committed suicide in India according to the statistics released by the National Crime Records Bureau. Suicide note is one of the most important sources to understand suicide, which may be beneficial in suicide prevention. Studies on suicidal notes from this part of the world are sparse. The aim was to study the themes in suicide notes that might be useful in prevention strategies. A descriptive study of all suicide notes of those individuals who committed suicide between 2010 and 2013 available with Police Department, Mysore district was obtained and analyzed. A total of 22 suicide note were available. A majority of suicide note was in age group of 16-40 years (86%) and most were men (59%). All suicide notes were handwritten, the majority (70%) in regional language Kannada. Length of notes varied from just few words to few pages. Contents of suicide notes included apology/shame/guilt (80%), love for those left behind (55%) and instruction regarding practical affairs (23%). Most have blamed none for the act (50%). 23% mentioned that they are committing suicide to prove their innocence. 32% mentioned a last wish. The majority of suicidal note contained "guilt" which is a strong indicator of possible depression in deceased. Creating awareness about suicide among public and ensuring access to professionals trained in suicide prevention is need of the hour in this part of the world.

    The term ''Modal Study'' refers to a research program conducted for the Nuclear Regulatory Commission (NRC) on the level of protection provided by NRC-certified packages during the shipment of spent nuclear fuel form U.S. power reactors. The objective of the study was to examine the response of the packages to actual highway and railway accident conditions. The Modal Study results show that NRC-certified spent fuel casks would perform their safety functions under severe, actual accident conditions. The study also explains how NRC's cask design conditions, which are expressed in engineering terms, relate to actual accident conditions, with which the public is more familiar. The Modal Study, along with other transportation studies, physical testing of casks, and the spent fuel shipment safety record confirm the view that casks provide a high level of public safety during spent fuel transport

    The Office of Exploration has established a process whereby all NASA field centers and other NASA Headquarters offices participate in the formulation and analysis of a wide range of mission strategies. These strategies were manifested into specific scenarios or candidate case studies. The case studies provided a systematic approach into analyzing each mission element. First, each case study must address several major themes and rationale including: national pride and international prestige, advancement of scientific knowledge, a catalyst for technology, economic benefits, space enterprise, international cooperation, and education and excellence. Second, the set of candidate case studies are formulated to encompass the technology requirement limits in the life sciences, launch capabilities, space transfer, automation, and robotics in space operations, power, and propulsion. The first set of reference case studies identify three major strategies: human expeditions, science outposts, and evolutionary expansion. During the past year, four case studies were examined to explore these strategies. The expeditionary missions include the Human Expedition to Phobos and Human Expedition to Mars case studies. The Lunar Observatory and Lunar Outpost to Early Mars Evolution case studies examined the later two strategies. This set of case studies established the framework to perform detailed mission analysis and system engineering to define a host of concepts and requirements for various space systems and advanced technologies. The details of each mission are described and, specifically, the results affecting the advanced technologies required to accomplish each mission scenario are presented.

  11. Towards Marxian Internet Studies

    Directory of Open Access Journals (Sweden)

    Christian Fuchs

    2012-05-01

    Full Text Available This article gives an overview of example approaches of Critical Internet Studies and points out key concepts of this field. Critical Cyberculture Studies and Critical Political Economy/Critical Theory of the Internet are identified as two approaches in Critical Internet Studies. The paper also discusses the role of 11 Marxian concepts for Critical Internet Studies. Marxian concepts that have been reflected in Critical Internet Studies include: dialectics, capitalism, commodification, surplus value/exploitation/alienation/class, globalization, ideology, class struggle, commons, public sphere, communism, and aesthetics. The paper points out the importance of explicitly acknowledging the importance of Karl Marx’s thinking in Critical Internet Studies. Marx’s concepts are today frequently used implicitly, without acknowledging and engaging with their roots. A critique of the approach of “Critical” Cyberculture Studies is advanced. This approach is compared to the approaches of Critical Theory and Critical Political Economy of the Internet. The difference between these two approaches reflects the debate about class exploitation and non-class domination between Cultural Studies and Critical Political Economy in Media and Communication Studies.

  14. Ca-48 metabolism studies

    International Nuclear Information System (INIS)

    Van der Merwe, D.G.

    1987-03-01

    Calcium metabolism has been studied in depth physiologically and is a relatively well-understood element in biochemistry and medicine. There is still only restricted knowledge of the metabolic fate of calcium in normal and abnormal paediatric subjects. The latter is partially owing to inadequate techniques for tracing and modelling calcium pathways in children. The advent of radioactive tracers has unquestionably enhanced medical research and improved the quality of many metabolic studies. The present study was aimed at the development, promotion and justification of a new tracer technique using the stable isotope, calcium-48. The obvious advantages of such a technique are its harmlessness tothe subject, its applicability to both short- and long-term studies as well as its usefulness to the study for which it was originally motivated, viz research defining the actual relationship between a calcium-deficient diet and the occurrence of rickets in rural Black children in South Africa. Exploratory instrumental analyses were performed specifically with serum samples. This proved successful enough to develop a less specific pre-concentration technique which improved the sensitivity and reduces the cost of doing calcium-48 metabolism studies. The results of a simple metabolic study are presented whereby the scope of the technique is demonstrated in a real situation. The possibilities and limitations of double-isotope metabolic studies are discussed, particularly with regard to strontium as the second tracer

    Directory of Open Access Journals (Sweden)

    Anne Holden Rønning

    2014-02-01

    Full Text Available Looking back to the past this paper discusses why Pacific studies and in particular Australasian studies became an area of interest in tertiary education in Europe. What subject areas initiated these studies, and how do past legacies shape the present? With cutbacks in higher education over the past two decades the future of interdisciplinary studies and the humanities looks bleak. At the same time due to global business and increased political communication across borders there is a vibrant interest in and need for such studies among businesses and students. For most Europeans the literature of settler countries, with their European legacy, makes access to ways of thought and culture easier than studies of countries with other mythological backgrounds. In today’s multicultural environment such studies can provide knowledge for an understanding of other cultures and increase tolerance of the ‘other’. Area studies have relevance to our situation in Europe with increased migrancy, not least as a result of Schengen and EU regulations.

    This paper advocates the need for a critical and cross-disciplinary research agenda on the field of digital technologies and tourism. The changing virtual landscape of tourism has received increased attention by tourism scholars. However, contemporary studies on information technologies (IT......) are approached mostly from a business administration perspective and informed by conceptual frameworks developed in management and marketing. IT studies in tourism are still at a stage similar to the first advocacy phase of tourism research in general (Jafari, 1990) and are seldom inspired by relevant...... to studying digital socio-technical systems and virtual mediation in tourism.

    Arnett, R.C.; Gephart, R.E.; Deju, R.A.; Cole, C.R.; Ahlstrom, S.W.

    1977-05-01

    This report documents the results of two Hanford groundwater scenario studies. The first study examines the hydrologic impact of increased groundwater recharge resulting from agricultural development in the Cold Creek Valley located west of the Hanford Reservation. The second study involves recovering liquid radioactive waste which has leaked into the groundwater flow system from a hypothetical buried tank containing high-level radioactive waste. The predictive and control capacity of the onsite Hanford modeling technology is used to evaluate both scenarios. The results of the first study indicate that Cold Creek Valley irrigationis unlikely to cause significant changes in the water table underlying the high-level waste areas or in the movement of radionuclides already in the groundwater. The hypothetical tank leak study showed that an active response (in this case waste recovery) can be modeled and is a possible alternative to passive monitoring of radionuclide movement in the unlikely event that high-level waste is introduced into the groundwater

    The Federal Radiation Protection Office carried out a retrospective cohort study on some 60,000 former employees of the SAG/SDAG Wismut. The purpose of the study was to validate the radon-related risk of acquiring lung cancer previously calculated from 11 jointly evaluated studies among miners on the basis of an independent, homogeneous data record of comparable size. A further goal was to study the risk of acquiring extrapulmonal tumours. This paper only briefly describes the sampling, design and methods used in the study, as these were already presented during the Radon Status Talks. The first follow-up on the cohort was completed in 2003. Around this time a job exposure matrix (JEM) suitable for scientific inquiries was made available by the professional miners' association and the roof organisation of professional trade associations (HVBG). This paper is the first to report on the outcome of the risk analysis in direct comparison with the results found by BEIR

  8. Effective Physics Study Habits

    Zettili, Nouredine

    2011-04-01

    We discuss the methods of efficient study habits and how they can be used by students to help them improve learning physics. In particular, we deal with ideas pertaining to the most effective techniques needed to help students improve their physics study skills. These ideas were developed as part of Project IMPACTSEED (IMproving Physics And Chemistry Teaching in SEcondary Education), an outreach grant funded by the Alabama Commission on Higher Education. This project is motivated by a major pressing local need: A large number of high school physics teachers teach out of field. In the presentation, focus on topics such as the skills of how to develop long term memory, how to improve concentration power, how to take class notes, how to prepare for and take exams, how to study scientific subjects such as physics. We argue that the student who conscientiously uses the methods of efficient study habits will be able to achieve higher results than the student who does not; moreover, a student equipped with the proper study skills will spend much less time to learn a subject than a student who has no good study habits. The underlying issue here is not the quantity of time allocated to the study efforts by the student, but the efficiency and quality of actions. This work is supported by the Alabama Commission on Higher Education as part of IMPACTSEED grant.

    2017-07-01

    Metabolomic analysis provides a powerful new tool for studies of Drosophila physiology. This approach allows investigators to detect thousands of chemical compounds in a single sample, representing the combined contributions of gene expression, enzyme activity, and environmental context. Metabolomics has been used for a wide range of studies in Drosophila , often providing new insights into gene function and metabolic state that could not be obtained using any other approach. In this review, we survey the uses of metabolomic analysis since its entry into the field. We also cover the major methods used for metabolomic studies in Drosophila and highlight new directions for future research. Copyright © 2017 by the Genetics Society of America.

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

  2. Optimum study designs.

    Science.gov (United States)

    Gu, C; Rao, D C

    2001-01-01

    Because simplistic designs will lead to prohibitively large sample sizes, the optimization of genetic study designs is critical for successfully mapping genes for complex diseases. Creative designs are necessary for detecting and amplifying the usually weak signals for complex traits. Two important outcomes of a study design--power and resolution--are implicitly tied together by the principle of uncertainty. Overemphasis on either one may lead to suboptimal designs. To achieve optimality for a particular study, therefore, practical measures such as cost-effectiveness must be used to strike a balance between power and resolution. In this light, the myriad of factors involved in study design can be checked for their effects on the ultimate outcomes, and the popular existing designs can be sorted into building blocks that may be useful for particular situations. It is hoped that imaginative construction of novel designs using such building blocks will lead to enhanced efficiency in finding genes for complex human traits.

    1988-07-01

    The objective of the Geomembrane Special Study was to asses the suitability of geomembranes in Uranium Mill Tailings Remedial Action (UMTRA) Project pile designs. Geomembranes, also called flexible membrane liners, are made of polymer resins and are thermoplastic materials. Part of the special study was to evaluate regulatory compliance and acceptability issues. This study was proposed because of the extensive use of geomembranes in hazardous waste site remedial actions and their accepted use in Resource Conservation and Recovery Act (RCRA) cells as both covers and liners to limit infiltration, or as part of leachate collection systems. This study has reviewed the recent geomembrane literature focusing on: (1) longevity; (2) performance; (3) constructibility; and (4) quality control/quality assurance considerations. In addition to these technical considerations, regulatory compliance and acceptability concerns were also evaluated. This report describes the results of the literature review, including correspondence with manufacturers, resin producers, experts in the field, and long-term major users. 12 refs., 2 tabs

    Background and Aims: Inflammatory bowel diseases [IBDs] include Crohn’s disease [CD], ulcerative colitis [UC], and IBD unclassified [IBDU]. In 2010 and 2011, the ECCO-EpiCom study found the worldwide highest incidence of inflammatory bowel disease [IBD] in the Faroe Islands: 83 per 100 000...... [European Standard Population, ESP]. The present study assessed the long-term time trends in IBD incidence in the Faroese population. Methods: In this population-based study, data were retrieved from the National Hospital of the Faroe Islands and included all incident cases of CD, UC, and IBDU diagnosed...... from 4 to 44, and for IBDU from 2 to 21 per 100 000 [ESP]. Conclusions: The high IBD incidence was found to be a relatively new phenomenon. The observed increase is unlikely to be an artefact resulting from, for instance, better registration. Our study indicated a real and increasing disease burden...

    More than a year after the Persian Gulf War, scientists are still trying to assess the environmental impact of the estimated 6-8 million barrels of oil that were dumped into the gulf and to understand the environmental processes that take place in such a disturbance. Many atmospheric studies were done in the months immediately following the war, but oceanographic studies have been slower in getting started.The National Oceanic and Atmospheric Administration is currently spearheading a major oceanographic study being undertaken in the Persian Gulf by the research vessel Mt. Mitchell. The ship left its home port of Norfolk, Va., in mid-January and arrived in Muscat, Oman, on February 16 to begin a 100-day oceanographic and environmental survey. The six-leg cruise will feature physical oceanography, near-shore, and marine life studies.

    The purpose of this project was to study the feasibility of reusing major components of a software system that had been used to control the operations of a spacecraft launched in the 1980s. The study was done in the context of a ground data processing system that was to be rehosted from a large mainframe to an inexpensive workstation. The study concluded that a systematic approach using inexpensive tools could aid in the reengineering process by identifying a set of certified reusable components. The study also developed procedures for determining duplicate versions of software, which were created because of inadequate naming conventions. Such procedures reduced reengineering costs by approximately 19.4 percent.

    Much like individual microgrids, the range of opportunities and potential architectures of networked microgrids is very diverse. The goals of this scoping study are to provide an early assessment of research and development needs by examining the benefits of, risks created by, and risks to networked microgrids. At this time there are very few, if any, examples of deployed microgrid networks. In addition, there are very few tools to simulate or otherwise analyze the behavior of networked microgrids. In this setting, it is very difficult to evaluate networked microgrids systematically or quantitatively. At this early stage, this study is relying on inputs, estimations, and literature reviews by subject matter experts who are engaged in individual microgrid research and development projects, i.e., the authors of this study The initial step of the study gathered input about the potential opportunities provided by networked microgrids from these subject matter experts. These opportunities were divided between the subject matter experts for further review. Part 2 of this study is comprised of these reviews. Part 1 of this study is a summary of the benefits and risks identified in the reviews in Part 2 and synthesis of the research needs required to enable networked microgrids.

    This study is an effort to bring into light data related to children with Wilms' tumor managed at Islamabad as local literature on this topic is lacking. It was retrospective study. The study was conducted at Children Hospital, Pakistan Institute of Medical Science, Islamabad between January, 1987 and December 1995. All patients managed during the study period were included in the study. In all the patients complete blood count (CBC), urine analysis (D/R),X-ray abdomen and chest, ultrasound abdomen and in selected cases CT scan were performed. National Wilms' Tumor Study Group (NWTS 3) protocol was followed for further management. Fifty patients including 28 males and 22 females with the age range from 9 months to 8 years were managed in 9 years period. Left kidney was involved in 31 patients. Most of the tumors were solid on ultrasound, 76% patients were in stage III and IV. In one case bilateral involvement of kidney was found. Forty patients underwent primary surgery. Only 14 patients received complete course of chemotherapy while 31 radiotherapy. Nineteen patients died and 15 lost to follow-up. The survival and mortality rates are comparable to NWTS-3 results, although, most of the patients were presented in advance stage of Wilms tumor. The survival of these patients can be improved by increasing awareness of society through electronic and print media. (author)

  15. The soul in the mediaeval Psalter

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available The soul in the mediaeval Psalter The paper is an attempt to examine what lies at the heart and soul of the mediaeval Psalter in the contemporaneous approach(es to its vernacularisations. In particular, the paper investigates the applications of the mediaeval translation theory in relation to a 12th-century Anglo-Norman, a 15th-century Middle French and four 14th-century Middle English prose Psalter renditions, with a view to locate them within the spirit of the attitude to biblical translations current in the Middle Ages and against the backdrop of the position of the Psalter in the period. In practical terms, the analysis is conducted on the basis of the equivalent selection strategies for rendering four Latin nouns central to the Psalter: anima, animae ‘soul,’ cor, cordis ‘heart’ and, perhaps surprisingly, ren, renis ‘kidney’ and lumbus, lumbi ‘loins’. All cases of variation in this respect are studied closely from intra- as well as extra-textual perspectives in order to establish the possible reasons behind the divergences, as these constitute exceptions rather than the rule, even in apparently heterodox renditions.   Dusza w średniowiecznym Psałterzu Artykuł stanowi próbę bliższego przyjrzenia się podstawowym zasadom średniowiecznego podejścia do tłumaczenia psałterza na języki wernakularne.

    2016-10-01

    Full Text Available With the rise of social media platforms based on the sharing of pictures and videos, the question of how such platforms should be studied arises. Previous research on social media (content has mainly focused on text (written words and the rather text-based social media platforms Twitter and Facebook. Drawing on research in the fields of visual, political, and business communication, we introduce a methodological framework to study the fast-growing image-sharing service Instagram. This methodological framework was developed to study political parties’ Instagram accounts and tested by means of a study of Swedish political parties during the 2014 election campaign. In this article, we adapt the framework to also study other types of organizations active on Instagram by focusing on the following main questions: Do organizations only use Instagram to share one-way information, focusing on disseminating information and self-presentation? Or is Instagram used for two-way communication to establish and cultivate organization-public relationships? We introduce and discuss the coding of variables with respect to four clusters: the perception of the posting, image management, integration, and interactivity.

  17. Impact studies at Winfrith

    International Nuclear Information System (INIS)

    Cooper, C.A.; Wicks, S.J.

    1987-02-01

    Analytical and experimental studies of subsonic impacts on nuclear reactor plant structures have been in progress at Winfrith since 1977. These studies have examined the behaviour of concrete and metal structures under the impact of missiles typifying those derived either from the plant itself or from external sources, such as crashing aircraft. During 1986 the Winfrith programme was expanded to include studies of the behaviour of radioactive materials transport containers under impact conditions. This report initially describes the experimental facilities available for impact studies at Winfrith. These include both compressed air guns, capable of delivering payloads of up to 65 kg at sonic velocity or payloads up to 2 tonnes at speeds up to 45 ms -1 , and drop test facilities for impact testing of models, up to full-scale radioactive materials transport flasks, at relatively low speeds. Supporting facilities include a small concrete manufacturing laboratory to produce concrete targets. Assessments of the resistance of concrete or metal structures to impact damage are performed using empirical or semi-empirical correlations, derived from data obtained in well-characterised experiments, or using structural dynamics finite element codes. The codes used by the analysts and the computing facilities available for impact analysis work are described. Finally the current programme of impact studies is reviewed, recent progress is summarised and future plans outlined. (author)

    1991-01-01

    Evidence from both human and rodent studies has indicated that alterations in immunological parameters occur after space flight. The number of flight experiments has been small, and the full breadth of immunological alterations occurring after space flight remains to be established. Among the major effects on immune responses after space flight that have been reported are: alterations in lymphocyte blastogenesis and natural killer cell activity, alterations in production of cytokines, changes in leukocyte sub-population distribution, and decreases in the ability in the ability of bone marrow cells to respond to colony stimulating factors. Changes have been reported in immunological parameters of both humans and rodents. The significance of these alterations in relation to resistance to infection remains to be established. The current study involved a determination of the effects of flight on Cosmos mission 2044 on leukocyte subset distribution and the sensitivity of bone marrow cells to colony stimulating factor-GM. A parallel study with antiorthostatic suspension was also carried out. The study involved repetition and expansion of studies carried out on Cosmos 1887.

    The purpose of this study is to elucidate the issues involved in developing a Laboratory Microfusion Capability (LMC) which is the major objective of the Inertial Confinement Fusion (ICF) program within the purview of the Department of Energy's Defense Programs. The study was initiated to support a number of DOE management needs: to provide insight for the evolution of the ICF program; to afford guidance to the ICF laboratories in planning their research and development programs; to inform Congress and others of the details and implications of the LMC; to identify criteria for selection of a concept for the Laboratory Microfusion Facility and to develop a coordinated plan for the realization of an LMC. As originally proposed, the LMC study was divided into two phases. The first phase identifies the purpose and potential utility of the LMC, the regime of its performance parameters, driver independent design issues and requirements, its development goals and requirements, and associated technical, management, staffing, environmental, and other developmental and operational issues. The second phase addresses driver-dependent issues such as specific design, range of performance capabilities, and cost. The study includes four driver options; the neodymium-glass solid state laser, the krypton fluoride excimer gas laser, the light-ion accelerator, and the heavy-ion induction linear accelerator. The results of the Phase II study are described in the present report

    The study is a long-term prospective cohort study of lung cancer and possibility other causes of death. The study population includes inhabitants of the area, who had resided there for at three years and at least one of these between 1.1.1960 and 21.12.1989. A total of 11865 inhabitants satisfied these criteria. The cumulative exposure of each respondent is being assessed on the basis of measurements in dwellings, time spent there and estimation of previous exposure levels by a model accounting for constructional changes in buildings. One year lasting measurements of radon daughter products by integral dosimeters (Kodak film LR 115) were performed in practically all dwellings of the specified area. Radon measurements in houses in term of equilibrium concentration are compared with the results of a pilot study in Petrovice in 1990-91 which gave the stimulus for the epidemiological study. The distribution of death causes and ratio of observed (O) to expected (E) cases among collected death cases in the cohort, generally, somewhat lower ratios than one reflect the non-industrial character of the region, with the exception of lung cancer in man. The differences in the O/E ratios for lung cancer among the separate communities indicate that even in the situation of generally lower mortality, the dependence of lung cancer mortality on radon.

    The results of a series of telephone interviews with groups of users of information on photovoltaics (PV) are described. These results, part of a larger study on many different solar technologies, identify types of information each group needed and the best ways to get information to each group. The report is 1 of 10 discussing study results. The overall study provides baseline data about information needs in the solar community. It covers these technological areas: photovoltaics, passive solar heating and cooling, active solar heating and cooling, biomass energy, solar thermal electric power, solar industrial and agricultural process heat, wind energy, ocean energy, and advanced energy storage. An earlier study identified the information user groups in the solar community and the priority (to accelerate solar energy commercialization) of getting information to each group. In the current study only high-priority groups were examined. Results from seven PV groups respondents are analyzed in this report: DOE-Funded Researchers, Non-DOE-Funded Researchers, Researchers Working for Manufacturers, Representatives of Other Manufacturers, Representatives of Utilities, Electric Power Engineers, and Educators.

    The two major thrusts of the environmental health studies have been in the areas of health physics aspects of fusion power and methodology for assessing health effects related to nuclear facilities. Researchers were unable to discern a dose-response relationship or to find adverse health effects in the local population around nuclear facilities which might be related to radiation exposure. A second study analyzed the trends in incidence of cancer, congenital malformation, and fetal and infant mortality for Oak Ridge, Anderson County, and Roane County relative to Tennessee. Finally, a more in-depth study on congenital malformations and fetal mortality trends for nine East Tennessee counties surrounding Oak Ridge was completed. The objective of the Health Physics Aspects of Fusion Power Program is to provide, on a timely basis, scientific information and technical evaluations on the potential impacts of fusion power to occupational workers and to members of the public. The primary areas of study in this program during the past year have been (1) factors affecting calculations of dose resulting from a release of tritium, (2) an assessment of the potential for reducing occupational risk from exposures to tritium, and (3) experimental studies of tritium conversion from molecular hydrogen to tritiated water

    1986-01-01

    The object of this book is to discuss and evaluate an area of Nuclear Magnetic Resonance which to date has been less emphasized than it might be, namely the use of NMR for functional studies. The book commences with a discussion of the areas in which the NMR techniques might be needed due to deficiencies in other techniques. The physics of NMR especially relating to functional measurement are then explained. Technical factors in producing functional images are discussed and the use of paramagnetic substances for carrying out flow studies are detailed. Particular attention is paid to specific studies in the various organs. The book ends with a survey of imaging in each organ and the relation of NMR images to other techniques such as ultrasound, nuclear medicine and X-rays

    Florida phosphate deposits contain higher levels of uranium than most other soils and rocks, thus exposing the population to higher-than-desirable levels of radon and its short-lived daughters. The Florida Legislature ordered a survey of significant land areas where an environmental radiation standard should be applied. Among other things, the study assessed indoor radon in 6,000 homes, soil radon at 3,000 residences, and all data existing prior to the study. The report explains the purpose of the study, how it was designed and conducted, and its results. It concludes with a discussion of radon/radon decay product equilibrium factor, correlation between indoor and soil radon, and preliminary attempts to develop a safe threshold for soil radon below which few elevated indoor levels would be anticipated

    This report presents the results from a study of various sealing alternatives for the WIPP sealing system. Overall, the sealing system has the purpose of reducing to the extent possible the potential for fluids (either gas or liquid) from entering or leaving the repository. The sealing system is divided into three subsystems: drift and panel seals within the repository horizon, shaft seals in each of the four shafts, and borehole seals. Alternatives to the baseline configuration for the WIPP seal system design included evaluating different geometries and schedules for seal component installations and the use of different materials for seal components. Order-of-magnitude costs for the various alternatives were prepared as part of the study. Firm recommendations are not presented, but the advantages and disadvantages of the alternatives are discussed. Technical information deficiencies are identified and studies are outlined which can provide required information

    Parylene C is used in a device because of its conformable deposition and other advantages. Techniques to study Parylene C aging were developed, and "lessons learned" that could be utilized for future studies are the result of this initial study. Differential Scanning Calorimetry yielded temperature ranges for Parylene C aging as well as post-deposition treatment. Post-deposition techniques are suggested to improve Parylene C performance. Sample preparation was critical to aging regimen. Short-term (%7E40 days) aging experiments with free standing and ceramic-supported Parylene C films highlighted "lessons learned" which stressed further investigations in order to refine sample preparation (film thickness, single sided uniform coating, machine versus laser cutting, annealing time, temperature) and testing issues ("necking") for robust accelerated aging of Parylene C.

  11. Underground layout tradeoff study

    International Nuclear Information System (INIS)

    1988-01-01

    This report presents the results of a technical and economic comparative study of four alternative underground layouts for a nuclear waste geologic repository in salt. The four alternatives considered in this study are (1) separate areas for spent fuel (SF) and commercial high-level waste (CHLW); (2) panel alternation, in which SF and CHLW are emplaced in adjacent panels of rooms; (3) room alternation, in which SF and CHLW are emplaced in adjacent rooms within each panel; and (4) intimate mixture, in which SF and CHLW are emplaced in random order within each storage room. The study concludes that (1) cost is not an important factor; (2) the separate-areas and intimate-mixture alternatives appear, technically, to be more desirable than the other alternatives; and (3) the selection between the separate-areas and intimate mixture alternatives depends upon future resolution of site-specific and reprocessing questions. 5 refs., 6 figs., 12 tabs

    Full Text Available This podcast is a recording of a research seminar that took place on December 3, 2015, at the University of Westminster's Communication and Media Research Institute (CAMRI. In this contribution, David Gauntlett discusses his new book, Making Media Studies, and other new work. In Making Media Studies (Peter Lang, 2015, Gauntlett proposes a vision of media studies based around doing and making – not about the acquisition of skills, as such, but an experience of building knowledge and understanding through creative hands-on engagement with all kinds of media. Gauntlett suggests that media studies scholars have failed to recognise the significance of everyday creativity – the vital drive of people to make, exchange, and learn together, supported by online networks. He argues that we should think about media in terms of conversations, inspirations, and making things happen. Media studies can be about genuine social change, he suggests, if we recognise the significance of everyday creativity, work to transform our tools, and learn to use them wisely. David Gauntlett is a Professor in the School of Media, Arts and Design at the University of Westminster, where he is also the School's Co-Director of Research. He is the author of several books, including: Creative Explorations (2007, Media, Gender and Identity: An Introduction (2nd edition 2008, Making is Connecting (2011, and Making Media Studies (2015. He has made a number of popular online resources, videos and playthings, and has pioneered creative research and workshop methods.

    Full Text Available This article presents an overview of rheoencephalography (REG – electrical impedance measurements of the brain – and summarizes past and ongoing research to develop medical applications of REG for neuro-critical care and for primary prevention of stroke and cardiovascular disease. The availability of advanced electronics and computation has opened up the potential for use of REG technology as a noninvasive, continuous and inexpensive brain monitor for military and civilian applications. The clinical background information presented here introduces physiological and clinical environments where REG has potential for use in research and clinical settings. REG studies over the past three decades have involved in vitro and in vivo groups (animal and human, including more than 1500 measurements and related electronic and computational results and practical applications. In vitro studies helped researchers understand the flow/volume relationship between Doppler ultrasound and electrical impedance signals and supported development of REG data processing methods. In animal studies, REG was used to monitor the lower limit of cerebral blood flow (CBF autoregulation (AR using a newly developed algorithm. These animal studies also confirmed correlations between REG and measurements of carotid flow (CF and intracranial pressure (ICP. Human studies confirmed the applicability of REG for detecting cerebrovascular alteration, demonstrating the usefulness of REG in the field of stroke/cardio-vascular disease prevention. In these studies, REG was compared to known stroke risk factors and to results obtained using carotid ultrasound measurements. An intelligent REG system (Cerberus has been developed for primary stroke prevention. In these studies, the biologically relevant variables of the REG signal were pulse amplitude (minimum – maximum distance and duration of the anacrotic (rising portion of the REG pulse wave.

    Schizophrenia is associated with enormous morbidity, mortality, personal disability, and social cost. Although considerable research on schizophrenia has been performed, the etiology of this disease has not been fully elucidated. In recent years, imaging and genetic technologies have been developed dramatically. Disturbances in glutamate and gamma-aminobutyric acid (GABA)ergic neurotransmission may underlie the pathophysiology of schizophrenia. We attempted an integrative review, of studies pertaining to recent advances of schizophrenia research with a focus on neuroimaging and genetic studies. Additionally, we present the preliminary findings of the clinical research in our outpatient unit, specialized for early intervention, at the University of Tokyo Hospital. (author)

    This study investigates methods of automatically identifying and characterizing significant transitions in term usage over time. Within scientific literature, the occurrence of terms reflects the use of technologies and techniques as well as the study of specific species and materials. Transitions in terminology usage may be a result of vocabulary standardization or specialization in which terms are replaced with their shorter form. They may also be a result of new applications, combinations, alternatives, or interests that result in the appearance of new or existing terminology in unexpected contexts.

    Research is summarized on fuel, fertile, and cladding materials. Results of studies in the field of solid state sciences are also reported. It was found during the studies on the thermal diffusion release of /sup 133/Xe from irradiated thoria--urania powders that during prolonged annealing at high temperatures, there were several sudden burst releases of /sup 133/Xe as a function of time. These sudden bursts appear to be related to the particle size of the powders. Studies on the phase composition of U/sub 3/O/sub 8//su established that the phase obtained at room temperature after heating at 850 deg K is always oxygen deficient. Results of studies on the different modifications of U/sub 3/O/sub 8/ indicated that the so-called delta-phase has a crystal structure almost identical with the beta-phase, yet there were differences in the heats of transition of each of these phases to the alpha-U/sub 3/O/sub 8/ phase at 130 deg C. Studies on fast neutron damage in stainless steel were initiated and results related to damage by void formation were obtained even when the fluencies were only moderately high. Studies on the phase transformations in solids brought out the unusual phase transition behavior of KNO/sub 3/. It was established that the phase transformation attributed to the orthorhombic (II) to the trigonal (I) transition at 129 deg C is essentially a 2-step transition. Results of differential scanning colorimeter (DSC) studies also revealed a peculiar feature which is as yet not understood, namely that on cooling, differential thermal analysis (DTA) showed a III to II phase transition; this is not seen in the DSC. The capabilities of the DSC technique to delineate temperatures of magnetic transitions were demonstrated by studying the transitions in a number of standard substances (metals, alloys, and compounds). In studies on KMnF/sub 3/, it was further demonstrated that the DSC technique is superior in measuring and detecting the heats of crystallographic and

    This presentation described a wind farm post-commissioning study conducted at a wind farm owned by Helimax Energy Inc. The farm was located in a partly-forested, partly cultivated region in Quebec that featured gently rolling hills. Over 600 dwellings were located within 2 km of the wind farm, and 44 dwellings were within the wind farm's boundaries. The noise impact assessments were conducted at various points near the wind farm. The wind farm was designed using an International Standards Organization (ISO) noise propagation model and a 40 dBA to provide adequate setbacks. The study was conducted using 10 days of continuous measurements at selected points of a wind farm. Points of reception included points from 650 m to 800 m. Noise over 2 km was not thought to be contributed by the wind turbine. The nearest dwelling was 512 m from one of the farm's wind turbines. The study also considered ground factor, temperature, relative humidity, and the height of the receptors. Quebec noise level limits are 40 dBA at night, and 45 dBA during the day. Noise level limits are independent of wind speed. Measured noise contributions over 40 dBA were not observed during the measurement program. The wind turbines were only audible for 1 night out of the 30 night study period. It was concluded that the ISO noise propagation model is a reliable tool for conducting noise impact assessments. tabs., figs

    1995-01-01

    The purpose of this document is to study the solid waste issues brought about by a Type C Investigation; ''Disposal of Inappropriate Material in the Los Alamos County Landfill'' (May 28, 1993). The study was completed in August 1995 by Coleman Research Corporation, under subcontract number 405810005-Y for Los Alamos National Laboratory (LANL). The study confirmed the issues identified in the Type C investigation, and also ascertained further issues or problems. During the course of this study two incidents involving hazardous waste resulted in the inappropriate disposal of the waste. An accidental spill, on June 8, 1995, at one of Laboratory buildings was not handled correctly, and ended up in the LAC Landfill. Hazardous waste was disposed of in a solid waste container and sent to the Los Alamos County Landfill. An attempt to locate the hazardous waste at the LAC Landfill was not successful. The second incident involving hazardous waste was discovered by the FSS-8, during a random dumpster surveillance. An interim dumpster program managed by FSS-8 discovered hazardous waste and copper chips in the solid waste, on August 9, 1995. The hazardous waste and copper chips would have been transported to the LAC Landfill if the audit team had not brought the problem to the awareness of the facility waste management personnel

    Full Text Available An understanding of the clinical aspects of electrical storm (E-storms in patients with implantable cardiac shock devices (ICSDs: ICDs or cardiac resynchronization therapy with defibrillator [CRT-D] may provide important information for clinical management of patients with ICSDs. The Nippon Storm Study was organized by the Japanese Heart Rhythm Society (JHRS and Japanese Society of Electrocardiology and was designed to prospectively collect a variety of data from patients with ICSDs, with a focus on the incidence of E-storms and clinical conditions for the occurrence of an E-storm. Forty main ICSD centers in Japan are participating in the present study. From 2002, the JHRS began to collect ICSD patient data using website registration (termed Japanese cardiac defibrillator therapy registration, or JCDTR. This investigation aims to collect data on and investigate the general parameters of patients with ICSDs, such as clinical backgrounds of the patients, purposes of implantation, complications during the implantation procedure, and incidence of appropriate and inappropriate therapies from the ICSD. The Nippon Storm Study was planned as a sub-study of the JCDTR with focus on E-storms. We aim to achieve registration of more than 1000 ICSD patients and complete follow-up data collection, with the assumption of a 5–10% incidence of E-storms during the 2-year follow-up.

  14. Steam explosion studies review

    International Nuclear Information System (INIS)

    Hwang, Moon Kyu; Kim, Hee Dong

    1999-03-01

    When a cold liquid is brought into contact with a molten material with a temperature significantly higher than the liquid boiling point, an explosive interaction due to sudden fragmentation of the melt and rapid evaporation of the liquid may take place. This phenomenon is referred to as a steam explosion or vapor explosion. Depending upon the amount of the melt and the liquid involved, the mechanical energy released during a vapor explosion can be large enough to cause serious destruction. In hypothetical severe accidents which involve fuel melt down, subsequent interactions between the molten fuel and coolant may cause steam explosion. This process has been studied by many investigators in an effort to assess the likelihood of containment failure which leads to large scale release of radioactive materials to the environment. In an effort to understand the phenomenology of steam explosion, extensive studies has been performed so far. The report presents both experimental and analytical studies on steam explosion. As for the experimental studies, both small scale tests which involve usually less than 20 g of high temperature melt and medium/large scale tests which more than 1 kg of melt is used are reviewed. For the modelling part of steam explosions, mechanistic modelling as well as thermodynamic modelling is reviewed. (author)

    A repeated-measures pilot study was used to investigate acoustic changes in the voices of participants in a Fitzmaurice Voicework (FV) teacher certification program. Maximum phonation time (MPT) was also measured. Eleven participants with no reported voice problems were studied. Pretraining and posttraining recordings were made of each participant. Measures of MPT were made, and the recordings were analyzed for jitter, shimmer, and noise-to-harmonics ratio (NHR). The measure of effect size for MPT was moderate, and there was an overall increase in MPT from pretraining to posttraining, with 70% of participants showing an increase in MPT. The measure of effect sizes for jitter, shimmer, and NHR were small, with measurements showing no significant changes from pretraining to posttraining. There were indications that FV training may have positive outcomes for actors and professional voice users, particularly in increasing MPT. Further studies with larger subject groups are needed to investigate the significance of the increase in MPT noted in this study and to test whether FV training can help to lower rates of shimmer and jitter.

    1985-12-01

    Advanced commercial tokamak studies were performed by the Fusion Engineering Design Center (FEDC) as a participant in the Tokamak Power Systems Studies (TPSS) project coordinated by the Office of Fusion Energy. The FEDC studies addressed the issues of tokamak reactor cost, size, and complexity. A scoping study model was developed to determine the effect of beta on tokamak economics, and it was found that a competitive cost of electricity could be achieved at a beta of 10 to 15%. The implications of operating at a beta of up to 25% were also addressed. It was found that the economics of fusion, like those of fission, improve as unit size increases. However, small units were found to be competitive as elements of a multiplex plant, provided that unit cost and maintenance time reductions are realized for the small units. The modular tokamak configuration combined several new approaches to develop a less complex and lower cost reactor. The modular design combines the toroidal field coil with the reactor structure, locates the primary vacuum boundary at the reactor cell wall, and uses a vertical assembly and maintenance approach. 12 refs., 19 figs

    1997-01-01

    The study of the nuclei far off stability valley is of much interest for testing the nuclear models established for the stable nuclei but also for astrophysics to understand the nucleosynthesis. Experiments aim to measure the mass and lifetime, to build the decay schemes and also to study the structure and the properties of these nuclei. The radioactive beam group focused its research on light neutron-rich nuclei having a halo neutron structure. Mass measurements in N ∼ Z nuclei namely in A ∼ 60-80 proton-rich nuclei, important for understanding the rp process, are mentioned, as well as in nuclei in the 100 Sn region. In the newly obtained 26 O and 28 O nuclei the lifetimes, the probabilities of emission of one for more neutrons were determined. The data analysis has permitted to determine also for the first time the lifetimes of 27,29 F and 30 Ne. Studies of nuclei in the 100 Sn region, near the proton drip line in the ground and isomeric states are now under way. The spectroscopy (energy levels, gamma emissions, etc.) of the neutron-rich nuclei produced by the 36 S fragmentation has been carried out in 31 Ne, 17 B and 29 F. Studies by Coulomb excitation of the 2 + excited states and associated probability B (E2) in O, Ne, Ni and Zn are now analysed

    1995-12-01

    Soil washing was identified as a viable treatment process option for remediating soil at the FEMP Environmental Management Project (FEMP). Little information relative to the specific application and potential effectiveness of the soil washing process exists that applies to the types of soil at the FEMP. To properly evaluate this process option in conjunction with the ongoing FEMP Remedial Investigation/Feasibility Study (RI/FS), a treatability testing program was necessary to provide a foundation for a detailed technical evaluation of the viability of the process. In August 1991, efforts were initiated to develop a work plan and experimental design for investigating the effectiveness of soil washing on FEMP soil. In August 1992, the final Treatability Study Work Plan for Operable Unit 5: Soil Washing (DOE 1992) was issued. This document shall be referenced throughout the remainder of this report as the Treatability Study Work Plan (TSWP). The purpose of this treatability study was to generate data to support initial screening and the detailed analysis of alternatives for the Operable Unit 5 FS

    Waters, R.J.; Ochoa, R.; Fritz, K.D.; Craig, D.W.

    2000-01-01

    The Idaho Nuclear Technology and Engineering Center (INTEC) at the Idaho National Engineering and Environmental Laboratory contains radioactive liquid waste in underground storage tanks at the INTEC Tank Farm Facility (TFF). INTEC is currently treating the waste by evaporation to reduce the liquid volume for continued storage, and by calcination to reduce and convert the liquid to a dry waste form for long-term storage in calcine bins. Both treatment methods and activities in support of those treatment operations result in Newly Generated Liquid Waste (NGLW) being sent to TFF. The storage tanks in the TFF are underground, contained in concrete vaults with instrumentation, piping, transfer jets, and managed sumps in case of any liquid accumulation in the vault. The configuration of these tanks is such that Resource Conservation and Recovery Act (RCRA) regulations apply. The TFF tanks were assessed several years ago with respect to the RCRA regulations and they were found to be deficient. This study considers the configuration of the current tanks and the RCRA deficiencies identified for each. The study identifies four potential methods and proposes a means of correcting the deficiencies. The cost estimates included in the study account for construction cost; construction methods to minimize work exposure to chemical hazards, radioactive contamination, and ionizing radiation hazards; project logistics; and project schedule. The study also estimates the tank volumes benefit associated with each corrective action to support TFF liquid waste management planning

    Ash (e.g. thermalized helium from D-T) buildup in a tokamak can potentially prevent ignition and seriously degrade the fusion energy gain from driven system. This problem is most pronounced as the ratio of particle/energy confinement time increases towards the neoclassical limit. Yet much improved confinement of the fuel ions is desirable for a fusion reactor. The goals of the work described here were two fold: to study the effect of helium buildup on the energy balance for a tokamak, and consider methods of active control that might be employed to alleviate the problem. We examine ash buildup effect for both D-T and D- 3 He systems. Most examples used apply to the ARIES 1 D-T reactor design and to the ARIES 3 D- 3 He design since part of this was in support of these two designs. Then we report on brief studies of two potentially attractive control methods, namely controlled sawtooth and fishbone instabilities. The concept is that sawteeth or fishbones would be used on purpose periodically in order to ''flush'' out excess ash from the fusion core. Both methods are shown to feasible and attractive. More study is needed, however, since the phenomenona in which are physically complex. Still the pay off, namely, reduced ash buildup, is exceedingly important so that such studies desires strong attention

    Studies performed for the Rockwell Hanford Operations (RHO) were designed to either (1) identify the role of biota in the uptake and transport of radionuclides from low-level waste managemnt areas or (2) design and/or evaluate methods for reducing biological transport of radionuclides away from waste management areas. The completion and publication of documents reporting the results of previous studies was also emphasized this fiscal year. Field studies were designed to characterize insect and plant communities occupying low-level waste management areas and to evaluate pond ecosystem response to herbicide application. Laboratory studies involved the examination of (1) germination response in plant species proposed for surface stabilization on burial grounds, (2) a synthetic polymer matrix as a carrier and delivery system for phytotoxins to act as a barrier to plant root penetration of shallow-land low-level waste burial sites, and (3) factors responsible for differences in radionuclide availability to plants resulting from the chemical equilibration of radionuclides occurring under field conditions
