Full Text Available El presente trabajo propone la noción "performances marianistas" como clave de lectura de algunas de las auto-representaciones que Gabriela Mistral habría utilizado en un contexto sociopolítico específico, en el cual el "excepcionalismo" se presenta como estrategia conducente a la promesa de igualdad. Este análisis nos llevará a pensar en las construcciones de género y "raza" de las cuales dependen los sistemas de valores que sostuvieron "la femineidad legítima" en la época en la que Mistral vivió. El texto tiene tres partes: la primera enunciará algunos debates y tomará posición con respecto al relato del marianismo latinoamericano. La segunda, problematizará las estrategias paradójicas del "excepcionalismo". La última, propone una lectura de las figuras que sugiero leer bajo las claves del marianismo y del excepcionalismo: "la Maestra de América Latina" y "la Poeta Redentora".

Full Text Available This article analyses the expositions that the journalist Dora Mayer did regarding the “indigenous question” and the Peruvian nation, in a stage of deep social conflicts that take place in a context of economic modernization sustained on pre-modern labor relationships and indigenous oppression. We reconstructed her vision on how the relation between the components of the Peruvian Nation had to be, her critics towards indigenous exclusion and her warnings on the repercussions that the latter one had. The main purpose is to think about the impact of the double formation on critical conscience of the public opinion, as well as on civic education of the indigenous people that Dora Mayer did in El Deber Pro- Indígena (1912-1917.

En el artículo se abordan los planteamientos que la periodista Dora Mayer hiciera sobre la “cuestión indígena” y la nación peruana, en una etapa de profundos conflictos sociales surgidos en un entorno de modernización económica sustentada sobre relaciones laborales premodernas y opresión indígena. Reconstruimos su visión sobre cómo debía ser la relación entre los componentes de la nación peruana, sus críticas a la exclusión indígena y sus advertencias sobre las repercusiones disociadoras que ésta última tenía. El propósito central es reflexionar sobre el impacto de la doble labor de formación de conciencia crítica de la opinión pública y de educación cívica de los indígenas, que llevó a cabo Dora Mayer desde El Deber Pro-Indígena (1912-1917.

"Desierto": Territorio, desplazamiento y nostalgia en "Poema de Chile" de Gabriela Mistral

Soledad Falabella

2016-03-01

Full Text Available Poema de Chile de Gabriela Mistral surge a partir de la necesidad de curar la herida generada por un desplazamiento físico fuera de las fronteras personales y nacionales. Este desplazamiento implica enfrentarse a complejos movimientos de reconstitución de la identidad del sujeto, cuya "única casa" en este estado de diáspora, se convierte en la escritura. El texto puede ser visto, entonces, como un espacio constituido y marcado por las huellas de lucha entre el deseo de su escritura y la concreción de ésta. Se trata de un terreno multidimensional e inteligible, máquina textual móvil y flexible, capaz de contener la nebulosa de la memoria y de territorializar campos de sentido de aquello que no se quiere perder: el paisaje de una tierra chilena recuerdo deslocado de un espacio que ya no está. Gabriela Mistral's "Poema de Chile" arises from the need to close the wound originated by the physical desplacement away from personal and national frontiers. The displacement implies a confrontation with complex movements of self-identity reconstitution, whose "true and only" home in this state of diaspora converts into writing. The text can therefore be seen as a space constituted and marked down by the footprints left by a struggle between the desire of writing and its concretion. It has to do with a multidimensional and inteligible terrain a mobile and flexible textual machinery capable of containing the nebula of territorializing fields for that which must not be lost: the Chilean landscape as dislodged memory of a space which is no ore.

Chronic insomnia is defined as a persistent difficulty with sleep initiation maintenance or non-restorative sleep. The therapeutic standard of care for this condition is treatment with gamma-aminobutyric acid (GABA) A receptor modulators, which promote sleep but are associated with a panoply of side effects, including cognitive and memory impairment. Dual orexin receptor antagonists (DORAs) have recently emerged as an alternative therapeutic approach that acts via a distinct and more selective wake-attenuating mechanism with the potential to be associated with milder side effects. Given their distinct mechanism of action, the current work tested the hypothesis that DORAs and GABA A receptor modulators differentially regulate neurochemical pathways associated with differences in sleep architecture and cognitive performance induced by these pharmacological mechanisms. Our findings showed that DORA-22 suppresses the release of the wake neurotransmitter histamine in the lateral hypothalamus, prefrontal cortex, and hippocampus with no significant alterations in acetylcholine levels. In contrast, eszopiclone, commonly used as a GABA A modulator, inhibited acetylcholine secretion across brain regions with variable effects on histamine release depending on the extent of wakefulness induction. In normal waking rats, eszopiclone only transiently suppressed histamine secretion, whereas this suppression was more obvious under caffeine-induced wakefulness. Compared with the GABA A modulator eszopiclone, DORA-22 elicits a neurotransmitter profile consistent with wake reduction that does not impinge on neurotransmitter levels associated with cognition and rapid eye movement sleep. © 2017 International Society for Neurochemistry.

Canoe: An Autonomous Infrastructure-Free Indoor Navigation System

Kai Dong

2017-04-01

Full Text Available The development of the Internet of Things (IoT has accelerated research in indoor navigation systems, a majority of which rely on adequate wireless signals and sources. Nonetheless, deploying such a system requires periodic site-survey, which is time consuming and labor intensive. To address this issue, in this paper we present Canoe, an indoor navigation system that considers shopping mall scenarios. In our system, we do not assume any prior knowledge, such as floor-plan or the shop locations, access point placement or power settings, historical RSS measurements or fingerprints, etc. Instead, Canoe requires only that the shop owners collect and publish RSS values at the entrances of their shops and can direct a consumer to any of these shops by comparing the observed RSS values. The locations of the consumers and the shops are estimated using maximum likelihood estimation. In doing this, the direction of the target shop relative to the current orientation of the consumer can be precisely computed, such that the direction that a consumer should move can be determined. We have conducted extensive simulations using a real-world dataset. Our experiments in a real shopping mall demonstrate that if 50% of the shops publish their RSS values, Canoe can precisely navigate a consumer within 30 s, with an error rate below 9%.

Why DORA does not stand a chance in the biosciences

Gloeser, J.

2016-07-01

The San Francisco Declaration on Research Assessment (DORA) has become emblematic for the international movement against the use of journal impact factors (JIFs) in researchassessment. This movement gained an institutional stronghold in Australia when in 2010, i.e. even before DORA, the Australian National Health and Medical research Council decided to remove JIFs from their assessment of grant proposals. Given the strong dependency of Australian researchers on funding from the research councils, one could expect the decisions by the funding councils to have an impact on the use of JIFs in individual research assessment. The aim of this paper is to demonstrate that there was no impact beyond a change of language in assessments and justifications of decisions, and to explain why this is the case. Interviews with officers of the two funding councils, university managers and researchers in cell biology and biostatistics were conducted in Australia in March 2016. The interviews explored the use of impact factors in seven roles of a biomedical researcher’s roleset, namely reader, author, group leader, grant applicant, reviewer of grant applications, university employee and university manager. The JIF solved three major problems for incumbents of the various roles: it reduced complexity, increased efficiency, and compensated for unfamiliarity in cases in which assessments were required but could not be conducted by judging content. Its use has not been changed by the research council’s intervention. JIFs are unlikely to be overcome as tools for research assessment in the life sciences unless another tool that solves the same problems is offered. (Author)

Gabriela Mistral's «Sonnets to Ruth»: The Consolation of Passion

Directory of Open Access Journals (Sweden)

Howard M. Fraser

1978-08-01

Full Text Available As for many poets, the sonnet form presented the opportunity to Gabriela Mistral to perfect her poetic technique. This study examines in detail the Nobel Laureate's trio of sonnets commemorating the biblical matriarch Ruth. Mistral's treatment of the themes of alienation, self- sacrifice, and the search for human dignity features the contrasts of suffering and consolation which are present in the biblical narrative. But, alongside the thematic purposes which the pleasure/pain duality serves, Mistral exploits this opposition for technical and structural reasons. She uses the feelings of love and pain as an organizational device in her treatment of time, characters and diction. The discipline with which she handled traditional metres, in this case the sonnet, reveals that Mistral was a capable and mature poet at an early age.

Du, Jing; Guo, Shirong; Sun, Jin; Shu, Sheng

2018-05-01

The mechanism of exogenous Spd-induced Ca(NO 3 ) 2 stress tolerance in cucumber was studied by proteomics and physiological analyses. Protein-protein interaction network revealed 13 key proteins involved in Spd-induced Ca(NO 3 ) 2 stress resistance. Ca(NO 3 ) 2 stress is one of the major reasons for secondary salinization that limits cucumber plant development in greenhouse. The conferred protective role of exogenous Spd on cucumber in response to Ca(NO 3 ) 2 stress cues involves changes at the cellular and physiological levels. To investigate the molecular foundation of exogenous Spd in Ca(NO 3 ) 2 stress tolerance, a proteomic approach was performed in our work. After a 9 days period of Ca(NO 3 ) 2 stress and/or exogenous Spd, 71 differential protein spots were confidently identified. The resulting proteins were enriched in seven different categories of biological processes, including protein metabolism, carbohydrate and energy metabolism, ROS homeostasis and stress defense, cell wall related, transcription, others and unknown. Protein metabolism (31.2%), carbohydrate and energy metabolism (15.6%), ROS homeostasis and stress defense (32.5%) were the three largest functional categories in cucumber root and most of them were significantly increased by exogenous Spd. The Spd-responsive protein interaction network revealed 13 key proteins, whose accumulation changes could be critical for Spd-induced resistance; all 13 proteins were upregulated by Spd at transcriptional and protein levels in response to Ca(NO 3 ) 2 stress. Furthermore, accumulation of antioxidant enzymes, non-enzymatic antioxidant and polyamines, along with reduction of H 2 O 2 and MDA, were detected after exogenous Spd application during Ca(NO 3 ) 2 stress. The results of these proteomic and physiological analyses in cucumber root may facilitate a better understanding of the underlying mechanism of Ca(NO 3 ) 2 stress tolerance mediated by exogenous Spd.

Abscisic Acid-Induced H2O2 Accumulation Enhances Antioxidant Capacity in Pumpkin-Grafted Cucumber Leaves under Ca(NO3)2 Stress

2016-01-01

With the aim to clarifying the role of the ABA/H2O2 signaling cascade in the regulating the antioxidant capacity of grafted cucumber plants in response to Ca(NO3)2 stress, we investigated the relationship between ABA-mediated H2O2 production and the activities of antioxidant enzymes in the leaves of pumpkin-grafted cucumber seedlings. The results showed that both ABA and H2O2 were detected in pumpkin-grafted cucumber seedlings in response to Ca(NO3)2 treatment within 0.5 h in the leaves and peaked at 3 and 6 h after Ca(NO3)2 treatment, respectively, compared to the levels under control conditions. The activities of superoxide dismutase (SOD), ascorbate peroxidase (APX), and peroxidase (POD) in pumpkin-grafted cucumber leaves gradually increased over time and peaked at 12 h of Ca(NO3)2 stress. Furthermore, in the leaves of pumpkin-grafted cucumber seedlings, the H2O2 generation, the antioxidant enzyme activities and the expression of SOD, POD and cAPX were strongly blocked by an inhibitor of ABA under Ca(NO3)2 stress, but this effect was eliminated by the addition of exogenous ABA. Moreover, the activities and gene expressions of these antioxidant enzymes in pumpkin-grafted leaves were almost inhibited under Ca(NO3)2 stress by pretreatment with ROS scavengers. These results suggest that the pumpkin grafting-induced ABA accumulation mediated H2O2 generation, resulting in the induction of antioxidant defense systems in leaves exposed to Ca(NO3)2 stress in the ABA/H2O2 signaling pathway.

Finds in Belize document Late Classic Maya salt making and canoe transport

Science.gov (United States)

McKillop, Heather

2005-01-01

How did people in preIndustrial ancient civilizations produce and distribute bulk items, such as salt, needed for everyday use by their large urban populations? This report focuses on the ancient Maya who obtained quantities of salt at cities in the interior of the Yucatan peninsula of Mexico, Belize, and Guatemala in an area where salt is scarce. I report the discovery of 41 Late Classic Maya saltworks (anno Domini 600–900) in Punta Ycacos Lagoon on the south coast of Belize, including one with the first-known ancient Maya canoe paddle. The discoveries add important empirical information for evaluating the extent of surplus salt production and river transport during the height of Late Classic civilization in the southern Maya lowlands. The discovery of the saltworks indicates that there was extensive production and distribution of goods and resources outside the cities in the interior of the Yucatan. The discovery of a wooden canoe paddle from one of the Punta Ycacos saltworks, Ka'k' Naab', ties the production of salt to its inland transport by rivers and documents the importance of canoe trade between the coast and the interior during the Late Classic. Archaeological discovery of multiple saltworks on the Belizean coast represents surplus production of salt destined largely for the inland Peten Maya during their Late Classic peak, underscoring the importance of non-state-controlled workshop production in preIndustrial societies.

Prehispanic Dugout Canoes in Mexico: A Typology Based on a Multidisciplinary Approach

Science.gov (United States)

Biar, Alexandra

2017-12-01

Navigation implies a deep knowledge of the environment in which it is practised as well as the development of correlated technologies and techniques. In fact, sailing in lakes, rivers, along coasts or in high seas requires specific skills. This is why watercraft reflect the specific expertise of cultures in relation to the available resources and materials. Navigation as a means of movement and boats as modes of transportation is a well-documented topic in Europe, Asia and the Pacific Ocean, whether focusing on antiquity or the present. Nonetheless, in the New World, especially in Mesoamerica where the Aztec, Tarascan and Mayan Empires flourished, indigenous maritime history has been thoroughly under-investigated. This article explores the first prehispanic dugout canoes of the region, based on a multidisciplinary approach for the Mexico and Pátzcuaro Basins, in the Late Postclassic period (AD 1325-1521). For the first time, a typology of these dugout types is proposed, with a discussion of the importance of dugout canoes as a means of transportation in Mesoamerican civilizations, where wheels and draught animals did not exist.

Numerical investigation of the triggering mechanisms of the Piz Dora sackung system (Val Mustair, Switzerland)

Science.gov (United States)

Riva, Federico; Agliardi, Federico; Crosta, Giovanni B.; Zanchi, Andrea

2015-04-01

Deep-Seated Gravitational Slope Deformations (DSGSD) are widespread phenomena in alpine environments, where they affect entire high-relief valley flanks involving huge rock volumes. Slope scale inherited structures related to ductile and brittle tectonic deformation can control the onset and development of DSGSD and the localization of strain in deep gravitational shear zones. Slope unloading, rock mass damage and hydrological perturbations related to deglaciation are considered important triggers of these phenomena in formerly glaciated areas. Furthermore, earthquake shaking and the long-term effects of seismicity in active tectonic areas might provide an additional triggering component. Nevertheless, the role played by these different processes and their interplay is not obvious, especially in geological context less typically favourable to DSGSD and in low-magnitude seismicity settings as the axial European Alps. We analysed the Piz Dora sackung system (Val Mustair, Switzerland), which affects conglomerates, meta-conglomerates and phyllites of the Austroalpine S-Charl nappe, involved in a slope-scale, WNW trending closed anticline fold. The area is actively uplifting, seismically active (maximum Mw>5) and experienced extensive glaciation during the LGM. The slope is affected by sharp gravitational morphostructures associated to the deep-seated sliding of 1.85 km3 of rock along a basal shear zone up to 300 m deep (Agliardi et al., 2014; Barbarano et al., 2015). We investigated the controlling role of inherited tectonic features and the relative influence of different candidate triggering processes (post-glacial debuttressing, related changes in slope hydrology, seismicity) through a series of 2D Distinct Element (DEM) numerical models set up using the code UDEC (ItascaTM). Based on field structural and geomechanical data, we discretized the slope into an ensemble of discontinuum domains, accounting for the slope-scale folded structure and characterised by unique

Ganjehsarabi, Hadi; Gungor, Ali [Department of Mechanical Engineering, Faculty of Engineering, Ege University (Turkey); Dincer, Ibrahim [Faculty of Engineering and Applied Science, University of Ontario (Canada)

2011-07-01

In the energy sector there is an urgent need to produce energy from renewable energy sources due to the rising demand, the depletion of fossil fuels and their effects on the environment. Geothermal power is a well-established energy resource and the aim of this research was to examine the energetic performance of a geothermal power plant. The studied power plant, Dora II, has a 9.5 MW power output and is situated in Aydin, Turkey. An evaluation of the plant's performance was carried out using an exergy analysis method on each of the plant's components. Results showed that the highest exergy destruction occurs in brine re-injection while the preheater had the best exergy efficiency; the plant had an overall exergetic efficiency of 29.6%. This study highlighted the components where significant exergy destructions take place so actions could be taken to improve the overall efficiency.

Effects of grafting with pumpkin rootstock on carbohydrate metabolism in cucumber seedlings under Ca(NO3)2 stress.

This study investigated the effects of grafting on the carbohydrate status and the enzymes of carbohydrate metabolism in self-grafted and grafted cucumber seedlings using the salt-tolerant pumpkin rootstock 'Qingzhen 1' (Cucurbita maxima × Cucurbita moschata) under 80 mM Ca(NO3)2 stress for 6 d. The growth of self-grafted seedlings was significantly inhibited after the treatment of Ca(NO3)2 stress, whereas the inhibition of growth was alleviated in pumpkin rootstock-grafted seedlings. Ca(NO3)2 stress increased the contents of the total soluble sugar, sucrose and fructose, but decreased the starch content in rootstock-grafted leaves. However, compared with self-grafted plants, rootstock-grafted seedlings were observed with a higher content of sucrose and total soluble sugar (TSS) under salt stress. Rootstock-grafted seedlings exhibited higher activities of acid invertase (AI), neutral invertase (NI) and phosphate sucrose synthase (SPS) of sucrose metabolism in leaves than that of self-grafted seedlings under salinity. Moreover, the activities of fructokinase (FK), hexokinase (HK), phosphofructokinase (PFK) and pyruvate kinase (PK) of glycolysis were maintained at a higher level in leaves of rootstock-grafted seedlings after Ca(NO3)2 stress. Additionally, rootstock-grafting decrease the high percentage enhancement of key enzymes gene expression in glycolysis in the scion leaves of cucumber seedlings induced by salt stress. These results suggest that the rootstock-grafting improved salt tolerance, which might play a role in elevated sucrose metabolism and a glycolytic pathway regulated by the pumpkin rootstock.

The purpose of this study was to analyze if different combinations of trials as well as mathematical models can modify the aerobic and anaerobic estimates from critical velocity protocol applied in canoe slalom. Fourteen male elite slalom kayakers from Brazilian canoe slalom team (K1) were evaluated. Athletes were submitted to four predictive trials of 150, 300, 450 and 600 meters in a lake and the time to complete each trial was recorded. Critical velocity (CV-aerobic parameter) and anaerobic paddling capacity (APC-anaerobic parameter) were obtained by three mathematical models (Linear1=distance-time; Linear 2=velocity-1/time and Non-Linear = time-velocity). Linear 1 was chosen for comparison of predictive trials combinations. Standard combination (SC) was considered as the four trials (150, 300, 450 and 600 m). High fits of regression were obtained from all mathematical models (range - R² = 0.96-1.00). Repeated measures ANOVA pointed out differences of all mathematical models for CV (p = 0.006) and APC (p = 0.016) as well as R² (p = 0.033). Estimates obtained from the first (1) and the fourth (4) predictive trials (150 m = lowest; and 600 m = highest, respectively) were similar and highly correlated (r=0.98 for CV and r = 0.96 for APC) with the SC. In summary, methodological aspects must be considered in critical velocity application in canoe slalom, since different combinations of trials as well as mathematical models resulted in different aerobic and anaerobic estimates. Key pointsGreat attention must be given for methodological concerns regarding critical velocity protocol applied on canoe slalom, since different estimates were obtained depending on the mathematical model and the predictive trials used.Linear 1 showed the best fits of regression. Furthermore, to the best of our knowledge and considering practical applications, this model is the easiest one to calculate the estimates from critical velocity protocol. Considering this, the abyss between science

Full Text Available Portugal is a turning point in Gabriela Mistral's consular and literary careers1. Her convalescence in Lisbon was transformed by the outbreak of the Spanish Civil War, as she worked to evacuate endangered Spanish academics, artists, and doctors. When Chilean authorities sought her transfer, her friends issued a storm of invitations from Geneva and Paris, which enabled her to continue contributing to humanitarian relief from Portugal, where she reoriented her interests towards America and increased her work's visibility by obtaining recognition in Europe. Careful study of her actions from Lisbon reveals their impact, which extended past her own life: the emigrants whom she helped contributed to universities and other institutions in Mexico, the U.S., and Argentina. Uncovering these actions comes from engaging in an accurate identification and sequencing of her published and unpublished writings, which reveals how she failed and recovered from her first two consular assignments.Portugal marca un punto de inflexión en la carrera literaria y consular de Gabriela Mistral. Su convalecencia en Lisboa se vio transformada por el estallido de la Guerra Civil española. Trabajó para evacuar académicos, artistas, y médicos. Cuando las autoridades chilenas buscaron trasladarla, sus amigos le facilitaron invitaciones de Ginebra y París, algo que le permitió seguir colaborando en el trabajo humanitario desde Portugal, donde consiguió una reorientación hacia América y una proyección mayor desde el reconocimiento europeo, que amplió la visibilidad de su trabajo y figura. Un análisis cuidadoso de sus acciones desde Lisboa revela el impacto que estas tuvieron más allá de su propia vida, a través de los emigrantes que contribuyeron a universidades y a otras instituciones en México, EE.UU. y Argentina. La identificación y secuenciación de sus escritos revela cómo ella fracasó y se recuperó del revés de sus dos primeras misiones consulares.

Full Text Available The book The Mothers’ Poems, combining the verses of Gabriela Mistral and drawings of the artist Andre Racz, has been reissued by Ediciones Radio Universidad de Chile with the support of the National Council for Culture and the Arts (CNCA of the Government of Chile in 2015. This is the third edition of the poems and the second in which Racz’s images are included, since it was published for first time in 1950. The theme of motherhood, women, fears and strengths are masterfully described by a woman who could never conceive but devotedly loved children and empathized with women. With such delivery, with his strokes Racz described the delicate and sensitive world of the pregnant woman. Both artists joined in the realization of this book as an expression of love and human solidarity.

Full Text Available Because the sanctions imposed on Iraq by the United Nations, programmed maintenance and wearing parts replacement has not been performed according to schedules in DORA Refinery Wastewater Unit, which resulted in higher phenol content and BOD5 in effluents disposed to river. The investigations showed that two main reasons were behind this problem: Firstly, increased emissions of hydrocarbons in the complexity of refinery equipment and Secondly, the decreased efficiency of the aerators in the biological. During the last few months, phenol average concentration in the effluent, after biological treatment was found to be between 0.06-0.13 mg/L, while COD was exceeding 110 mg/L after treatment in the same period. Considerable enhancement, has been indicated recently, after the following performances: First: Recycling wastewater from some heat exchangers, and the segregation of low and high strength of wastewaters, Second: Minimizing emissions of hydrocarbons from fluid catalytic cracking and steam cracking, Third: Replacement of driving motors of the aerators in the biological treatment unit. After replacement of these units, a significant decrease in phenol concentration was obtained in purified water (0.03-0.05 mg/L and COD of 60 mg/L before the tertiary treatment. It is concluded that a better quality of effluents has been obtained after a series of emissions control and wastewater treatment unit equipment maintenance performances.

Full Text Available Introduction Long-term training process need precise, scientific management, based on recognition indicators of fitness preparation, technical, mental health status of the player. Control is treated as a collection of information allowing to organize rational technological solution. Verification should provide high reliability and information of the test results, what is achieved by standardizing test conditions, sets of samples used in any of the disciplines and measurement techniques. Objective The objective was to calculate the training loads of female canoeing youth national team (sprint. In addition, attempts to answer the following questions: What was the structure of the annual training plans and whether it is consistent with the theory of training canoeist?; What was the pace and direction of changes in the volume of work within each group of training? Materials and methods The study used records of logs implementation training loads what competitors have done in the years 2009 to 2010. The analysis included data on training loads and boot. The loads presented as the number of kilometers completed during each season training and during each period of the season and in arbitrary units. Results and conclusions Based on the collected material research analysed training of female canoeing youth national team both in terms of its subject, as well as temporary structures. Every aspect of fitness requires adequate time, necessary to make adaptive changes. Therefore, it is necessary to vary the time required for development. Comparing the training load can be seen that in 2009 competitors have done more work in the run-up than in 2010, but much smaller loads can be seen in 2009 during start season comparing the training load during startup in 2010.

It is, fundamentally, the last will and inventory of goods of Vicente Salvador Gómez,' the contract that he carried out with the Convent of Santo Domingo of Valencia, for the realisation of three paintings on San Vicente's Ferrer life, and other notarial texts related with him, his father Pere and his brother Luciano that will allow us to better understand the biography and the pictorial work of this family of artists. In addition, the fact of having located the one mentioned inventory, dated after the purchase that Vicente Salvador made of the belongings left by Alonso Cano in the Chartreuse of Portacoeli of Valencia, will give us the opportunity to know, in some measure, the goods that Cano possessed in 1645, arnong them his library that, for the first time, it is published. Finally, with the study of several of Vicente's Salvador drawings we will be able to determine some og his labour bonds with the Madrid nobility, as well as to support the theory of his possible trip to Italy.

The Dora-Maira Unit (Italian Cottian Alps): a reservoir of ornamental stones locally and worldwide employed since Roman age

Science.gov (United States)

Borghi, Alessandro; Cadoppi, Paola; Antonella Dino, Giovanna

2015-04-01

The Dora-Maira is a geological unit belonging to the Penninic Domain of the Western Alps (NW Italy), which covers over 1000 km2 from the Susa to the Maira valleys, in the inner part of the Cottian Alps. It consists of different superposed complexes made of micaschists, fine-grained gneisses, quartzites, impure and dolomitic marbles, metabasites and various types of orthogneisses deriving from metamorphic transformation, during alpine orogeny, of a Palaeozoic upper continental crust and its Mesozoic carbonate cover. Thanks to the presence of different varieties of rocks, the Dora-Maira Unit can be considered as a reservoir of ornamental stones, locally employed, since Roman age, for military and religious buildings. Furthermore, these materials were used in Piedmont region for the construction of important historical palaces (17th and 18th centuries). Several varieties of gneisses, quartzites and marbles, exploited in the past and up to now, come from the Paleozoic basement. The most famous variety of gneiss is the so called "Luserna stone", a leucocratic gneiss characterized by a mylonitic fabric deriving from highly differentiated granitoids of Permian age. The first traces of Luserna Stone exploitation arise to the medieval age in the Pellice Valley). This material was widely employed in Turin, from Savoia kingdom period up to know. The very peculiar and precious application of Luserna stone were: Royal Palace and Venaria Reale Palace, Mole Antonelliana. Recently, it has been employed for the construction of Turin Metro stations (launched in 2006). Other varieties of orthogneisses, not yet exploited, are: Borgone and Vaie Stones, Villarfocchiardo and Cumiana Stones. They were used for the realization of the columns characterising the façade of several churches in Turin and in the piers of different bridges over the Po River. Another gneiss variety, with dioritic composition, is the Malanaggio Stone employed in the Fenestrelle Fortress. As for the palaeozoic

"The Best of Chile is now in Mexico". The Political Ideas and Pedagogical Work of Gabriela Mistral in Mexico (1922-1924

Directory of Open Access Journals (Sweden)

Fabio Moraga Valle

2014-01-01

Full Text Available This article looks at a brief and little-known period of the intellectual biography of the Chilean poet Gabriela Mistral (1889-1957, who was in Mexico from 1922 to 1924.  She arrived in Mexico to take part in Education Secretary Jose Vasconcelos’ project to implement cultural missions and rural education as primary axes of his post-revolutionary strategy to integrate country folk and indigenous peoples into the nation. This study focuses on two central areas of the poet’s life that have not been extensively researched, her political thought and her pedagogical ideas, both of which were formed not in formal education, but rather through her personal experiences and self-teaching. Contrary to traditional interpretations offered by biographers and literary experts, which suggest that Mistral fled under pressure from enemies and rivals and hating her native Chile, our hypothesis is that she chose to go to Mexico because it was the best place to carry out her pedagogical project and because she perceived there to be an atmosphere conducive to her political and intellectual aspirations.

Nitric oxide (NO) and hydrogen peroxide (H 2 O 2 ), two important signaling molecules, are stimulated in plants by abiotic stresses. In this study, we investigated the role of NO and its interplay with H 2 O 2 in the response of self-grafted (S-G) and salt-tolerant pumpkin-grafted (Cucurbita maxima × C. moschata) cucumber seedlings to 80 mM Ca(NO 3 ) 2 stress. Endogenous NO and H 2 O 2 production in S-G seedlings increased in a time-dependent manner, reaching maximum levels after 24 h of Ca(NO 3 ) 2 stress. In contrast, a transient increase in NO production, accompanied by H 2 O 2 accumulation, was observed at 2 h in rootstock-grafted plants. N w -Nitro-l-Arg methyl ester hydrochloride (l-NAME), an inhibitor of nitric oxide synthase (NOS), tungstate, an inhibitor of nitrate reductase (NR), and 2-(4-carboxyphenyl)-4,4,5,5-tetramethy-limidazoline-1-oxyl-3-oxide (cPTIO), a scavenger of NO, were found to significantly inhibit NO accumulation induced by salt stress in rootstock-grafted seedlings. H 2 O 2 production was unaffected by these stress conditions. Ca(NO 3 ) 2 stress-induced NO accumulation was blocked by pretreatment with an H 2 O 2 scavenger (dimethylthiourea, DMTU) and an inhibitor of NADPH oxidase (diphenyleneiodonium, DPI). In addition, maximum quantum yield of PSII (Fv/Fm), as well as the activities and transcript levels of antioxidant enzymes, were significantly decreased by salt stress in rootstock grafted seedlings after pretreatment with these above inhibitors; antioxidant enzyme transcript levels and activities were higher in rootstock-grafted seedlings compared with S-G seedlings. These results suggest that rootstock grafting could alleviate the oxidative damage induced by Ca(NO 3 ) 2 stress in cucumber seedlings, an effect that may be attributable to the involvement of NO in H 2 O 2 -dependent antioxidative metabolism. © 2016 Scandinavian Plant Physiology Society.

BACKGROUND Virtual reality (VR) training with motion-controlled console games can be incorporated into stroke rehabilitation programs. The use of a variety of gaming software can provide the patient with an opportunity to perform activities that are exciting, entertaining, and that may not be feasible in clinical environments. The aim of this preliminary randomized controlled study was to investigate the effects of game-based VR canoe paddling training, when combined with conventional physical rehabilitation programs, on postural balance and upper extremity function in 30 patients with subacute stroke. MATERIAL AND METHODS Thirty patients, who were within six months following the diagnosis of stroke, were randomly allocated to either the experimental group (n=15) or the control group (n=15). All participants participated in a conventional rehabilitation program. Also, the experimental group (n=15) performed the VR canoe paddling training for 30 minutes each day, three times per week, for five weeks. After five weeks, outcomes of changes in postural balance and upper extremity function were evaluated and compared between the two groups. RESULTS At five weeks, postural balance and upper extremity function showed significant improvements in both patients groups when compared with the baseline measurements (pGame-based VR canoe paddling training is an effective rehabilitation therapy that enhances postural balance and upper extremity function in patients with subacute stroke when combined with conventional physical rehabilitation programs.

Ten Canoes and the Ethnographic Photographs of Donald Thomson: ‘Animate Thought’ and ‘the Light of the World’

Directory of Open Access Journals (Sweden)

Anne Rutherford

2011-10-01

Full Text Available This article explores the genesis of the film Ten Canoes in the photographs taken by anthropologist Donald Thomson, in Arnhem Land, in the 1930s.  Thomson’s images profoundly informed the look and content of the film, and the paper traces this genealogy in order to identify a ‘cultural imaginary’ at work in the film. I argue that a close study of Thomson’s original photographs reveals an approach to photography and to culture that dramatically exceeds the boundaries of the detached anthropological/scientific gaze. Thomson’s vision is a highly tactile one. His images are as much an encounter with the light of the world as they are a document of a time, an environment and a culture; his lens is as much an organ of touch as an instrument of observation. In a remarkable example of what Tim Ingold has called ‘animate thought’, Thomson uses the materiality of photography to make manifest a life-world in which reeds, water and sky are as animate as human figures. Not easily accessible to established criteria for analysing ethnographic images, such as questions of self-reflexivity, Thomson’s polycentric images profoundly challenge the humanist assumptions of many contemporary approaches to reading images. This insight raises new questions about both ethnographic photography and the relationship between the photographs and Ten Canoes.

The Brossasco metagranite is part of the coherent ultrahigh-pressure metamorphic terrane in the Dora-Maira massif and, although it has reached Alpine peak metamorphic conditions of about 725 C/30 kbar, still locally preserves an undeformed magmatic texture. In order to obtain new chronological constraints on this key area of the western Alps, we studied the behaviour of the U-Th-Pb system in zircons and monazites from such an undeformed facies. Only zircon fractions containing very small needle-shaped inclusions are concordant at 304{+-}3 Ma. This result is interpreted as the emplacement age of the granite. All other zircons show an old inherited memory and the more U-rich of these crystals were affected by an episodic Pb loss with a poorly defined lower intercept at 60{+-}45 Ma. Both TIMS (thermo-ionisation mass spectrometry) and electron-microprobe analysis of monazites show that this last event has also disturbed their U-Pb and Th-Pb isotopic systems, without resetting them completely. Comparison with cofacial rock-types which have been completely reworked under these extreme P-T conditions shows that deformation and mass transfer as well as the nature of the protoliths and the characteristics of their zircons have a much more pronounced influence on the behaviour of isotopic systems than the temperature and/or pressure parameters. This evidence is an obvious limitation to the use of the blocking-temperature concept. (orig.)

Children of parents who suffer from mental health disorders are more likely to develop mental disorders than children of parents not suffering from mental disorders. For children at risk, preventive strategies are hardly available and, if available, rarely supported by a scientific evaluation. "Kanu - Gemeinsam weiterkommen (canoe - moving jointly forward)" is a preventive strategy that was developed within a research project focusing on primary prevention in children who live in families with parents affected by mental disorders. The intervention is characterised by a multi-modular concept and was tested in the adult psychiatric setting. Preliminary results indicate a preventive impact of the intervention programme. © Georg Thieme Verlag KG Stuttgart · New York.

NMR transverse relaxation time (T(2)) distribution of (1)H nuclei of water has been used to monitor the moisture condensation kinetics in Ca(NO(3))(2)  · (4)H(2)O-polluted Lecce stone, a calcareous stone with highly regular porous structure often utilized as basic material in Baroque buildings. Polluted samples have been exposed to water vapor adsorption at controlled relative humidity to mimic environmental conditions. In presence of pollutants, the T(2) distributions of water in stone exhibit a range of relaxation time values and amplitudes not observed in the unpolluted case. These characteristics could be exploited for in situ noninvasive detection of salt pollution in Lecce stone or as damage precursors in architectural buildings of cultural heritage interest.

Andrews, Steven S; Peria, William J; Yu, Richard C; Colman-Lerner, Alejandro; Brent, Roger

2016-11-23

Many cell signaling systems, including the yeast pheromone response system, exhibit "dose-response alignment" (DoRA), in which output of one or more downstream steps closely matches the fraction of occupied receptors. DoRA can improve the fidelity of transmitted dose information. Here, we searched systematically for biochemical network topologies that produced DoRA. Most networks, including many containing feedback and feedforward loops, could not produce DoRA. However, networks including "push-pull" mechanisms, in which the active form of a signaling species stimulates downstream activity and the nominally inactive form reduces downstream activity, enabled perfect DoRA. Networks containing feedbacks enabled DoRA, but only if they also compared feedback to input and adjusted output to match. Our results establish push-pull as a non-feedback mechanism to align output with variable input and maximize information transfer in signaling systems. They also suggest genetic approaches to determine whether particular signaling systems use feedback or push-pull control. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available The taxonomy of the coelomycetes has undergone dramatic changes in recent years, but remains controversial due to the high number of taxa involved, their poor morphological differentiation, the rare occurrence of the sexual morphs, and rapid loss of fertility in vitro. In the present study, we revisited the families Cucurbitariaceae and Didymellaceae (Pleosporales, Dothideomycetes, which include numerous plant pathogens, endophytic species associated with a wide host range, and saprobes. The taxonomy of two of the most relevant genera, i.e. Phoma and Pyrenochaeta, remains ambiguous after several phylogenetic studies, and needs further revision. We have studied a total of 143 strains of coelomycetes from clinical or environmental origin, by combining the LSU, ITS, tub2 and rpb2 sequences for a multi-locus analysis and a detailed morphological comparison. The resulting phylogenetic tree revealed that some fungi previously considered as members of Cucurbitariaceae represented five different families, and four of them, Neopyrenochaetaceae, Parapyrenochaetaceae, Pseudopyrenochaetaceae and Pyrenochaetopsidaceae, are proposed here as new. Furthermore, 13 new genera, 28 new species, and 20 new combinations are proposed within the Pleosporineae. Moreover, four new typifications are introduced to stabilise the taxonomy of these fungi.

Orexin receptor antagonist-induced sleep does not impair the ability to wake in response to emotionally salient acoustic stimuli in dogs

2014-05-01

Full Text Available The ability to awaken from sleep in response to important stimuli is a critical feature of normal sleep, as is maintaining sleep continuity in the presence of irrelevant background noise. Dual orexin receptor antagonists (DORAs effectively promote sleep across species by targeting the evolutionarily conserved wake-promoting orexin signaling pathway. This study in dogs investigated whether DORA-induced sleep preserved the ability to awaken appropriately to salient acoustic stimuli but remain asleep when exposed to irrelevant stimuli. Sleep and wake in response to DORAs, vehicle, GABA-A receptor modulators (diazepam, eszopiclone and zolpidem and antihistamine (diphenhydramine administration were evaluated in telemetry-implanted adult dogs with continuous electrocorticogram, electromyogram, electrooculogram, and activity recordings. DORAs induced sleep, but GABA-A modulators and antihistamine induced paradoxical hyperarousal. Thus, salience gating studies were conducted during DORA-22 (0.3, 1, and 5 mg/kg; day and night and vehicle nighttime sleep. The acoustic stimuli were either classically conditioned using food reward and positive attention (salient stimulus or presented randomly (neutral stimulus. Once conditioned, the tones were presented at sleep times corresponding to maximal DORA-22 exposure. In response to the salient stimuli, dogs woke completely from vehicle and orexin-antagonized sleep across all sleep stages but rarely awoke to neutral stimuli. Notably, acute pharmacological antagonism of orexin receptors paired with emotionally salient anticipation produced wake, not cataplexy, in a species where genetic (chronic loss of orexin receptor signaling leads to narcolepsy/cataplexy. DORA-induced sleep in this species thereby retains the desired capacity to awaken to emotionally salient acoustic stimuli while preserving uninterrupted sleep in response to irrelevant stimuli.

Full Text Available Dual orexin receptor antagonists (DORAs are a potential treatment for insomnia that function by blocking both the orexin 1 and orexin 2 receptors. The objective of the current study was to further confirm the impact of therapeutic mechanisms targeting insomnia on locomotor coordination and ethanol interaction using DORAs and gamma-aminobutyric acid (GABA-A receptor modulators of distinct chemical structure and pharmacologic properties in the context of sleep-promoting potential. The current study compared rat motor co-ordination after administration of DORAs, DORA-12 and almorexant, and GABA-A receptor modulators, zolpidem, eszopiclone and diazepam, alone or each in combination with ethanol. Motor performance was assessed by measuring time spent walking on a rotarod apparatus. Zolpidem, eszopiclone and diazepam (0.3–30 mg/kg administered orally [PO] impaired rotarod performance in a dose-dependent manner. Furthermore, all three GABA-A receptor modulators potentiated ethanol- (0.25–1.25 g/kg induced impairment on the rotarod. By contrast, neither DORA-12 (10–100 mg/kg, PO nor almorexant (30–300 mg/kg, PO impaired motor performance alone or in combination with ethanol. In addition, distinct differences in sleep architecture were observed between ethanol, GABA-A receptor modulators (zolpidem, eszopiclone and diazepam and DORA-12 in electroencephalogram studies in rats. These findings provide further evidence that orexin receptor antagonists have an improved motor side-effect profile compared with currently available sleep-promoting agents based on preclinical data and strengthen the rationale for further evaluation of these agents in clinical development.

EFFECT OF SELF-SELECTED AND INDUCED SLOW AND FAST PADDLING ON STROKE KINEMATICS DURING 1000 M OUTRIGGER CANOEING ERGOMETRY

Full Text Available This study aimed to identify the effect of different stroke rates on various kinematic parameters during 1000 m outrigger canoeing. Sixteen, experienced female outrigger canoeists completed three 1000 m outrigger ergometer time trials, one trial each using a self-selected, a Hawaiian ( 65 strokes·min-1 stroke rate. Stroke rate, stroke length, stroke time, proportion of time spent in propulsion and recovery, torso flexion angle and 'twist' were measured and compared with repeated measures ANOVAs. Stroke rate, stroke length and stroke time were significantly different across all interventions (p < 0.05 despite no difference in the percentage of time spent in the propulsive and recovery phases of the stroke. Stroke length and stroke time were negatively correlated to stroke rate for all interventions (r = -0.79 and -0.99, respectively. Female outrigger canoeists maintain consistent stroke kinematics throughout a 1000 m time trial, most likely as a learned skill to maximize crew paddling synchrony when paddling on-water. While the Hawaiian stroke rate resulted in the greatest trunk flexion movement and 'twist' action, this potential increased back injury risk may be offset by the slow stroke rate and long stroke length and hence slow rate of force development.

Chemical composition and evolution of tourmaline-supergroup minerals from the Sb hydrothermal veins in Rožňava area, Western Carpathians, Slovakia

Tourmaline-supergroup minerals are common gangue minerals in Sb-hydrothermal veins on Betliar - Straková, Čučma - Gabriela and Rožňava - Peter-Pavol vein deposits in the Rožňava area, Slovakia. Tourmaline-supergroup minerals form relatively large prismatic to radial aggregates of parallel black to greyish-black crystals. Tourmaline-supergroup minerals from Betliar - Straková and Rožňava - Peter-Pavol are almost homogeneous with intermediate schorl-dravite composition. Čučma - Gabriela tourmaline have distinct zoning with massive core of the schorlitic-to-feruvitic shifting to schorlitic-to-dravitic composition, and dravitic to magnesio-foititic rim. The tourmaline composition is influenced by two main substitutions, namely Ca(Mg,Fe)Na-1Al-1 and X □AlNa-1(Mg,Fe)-1. Betliar - Straková and Rožňava - Peter-Pavol tourmaline-supergroup minerals exhibit only small extents of the X □AlNa-1(Mg,Fe)-1 substitution. This substitution shifts the composition to magnesio-foitite in Čučma - Gabriela tourmaline. The decrease of Al in the core of Čučma - Gabriela tourmaline crystals is caused by extensive Ca(Mg,Fe)Na-1Al-1 substitution. The unit-cell dimensions of all investigated tourmaline-supergroup minerals indicate an octahedral disorder with the Z (Fe3++Mg) proportion calculated from empirical equations varying between 0.85 and 0.87 apfu (atoms per formula unit). Based on Mössbauer spectra, the Z Fe3+ content varied between 0.25 apfu in Betliar - Straková tourmaline and 0.45 apfu in Čučma - Gabriela sample. Based on Fe/(Fe + Mg) ratio, Betliar - Straková tourmaline is slightly enriched in Fe compared to Rožňava - Peter-Pavol, suggesting the impact of the host-rock composition; first are grown in Fe-richer acidic metarhyolitic rocks, latter in metapelites. In Čučma - Gabriela, the variations in Fe/(Fe + Mg) are very likely reflecting the change in fluid composition. Magnesio-foitite is the product of second-stage crystallization forming rims and

Como objetivo principal, pretende compreender os vários processos que levaram Ilhéus, cidade que surge subordinada ao campo, a passar da condição de espaço do cacau a espaço do turismo. Para alcançar esse objetivo, foram feitas entrevistas e pesquisas de natureza documental. Inicia-se o texto com uma digressão histórica sobre o processo de produção e reprodução socioespacial de Ilhéus, desde o século XVIII, quando chegaram a Ilhéus as primeiras mudas de cacau. Essa pesquisa revelou que diante da crise e das fracassadas tentativas de revitalizar a lavoura cacaueira, o turismo, atividade até então relegada a um segundo plano, passou a fazer parte da pauta de interesse da iniciativa privada e do poder público. Isso por força da necessidade de reerguer a economia regional.

Minor elements, HREE and d18O distribution in UHP garnets from the Dora-Maira massif (western Alps)

Brunet, F.; Chazot, G.; Vielzeuf, D.; Chopin, C.

The spatial distribution of minor elements, HREE and δ18O in garnet can be used as a probe of the availability and mobility of those elements and isotopes at the time of crystal growth, provided that the initial record was not significantly modified by intracrystalline diffusion and that growth took place under nearly constant pressure and temperature conditions. Garnets from three different Dora-Maira rock-types have been studied, (1) nearly pure pyrope (GT1) from the magnesian coesite-bearing quartzites, (2) almandine/pyrope dominant garnets (GT2) from jadeite-quartzite veins which crosscut the Mg-quartzite body, (3) almandine/grossular dominant garnets (GT3) from the country-rock gneiss, sampled in the vicinity of the quartzites. In GT1, minor elements are mainly Fe, Na and P. Na and P are incorporated according to a Na^+ + P5+ = Me2+ + Si4+ substitution with P_2O_5 contents up to 2000 to 2500 ppm. HREE concentrations obtained by LA-ICP-MS, vary by 2 orders of magnitude from core to rim. The δ18O ratio (Cameca 1270, Nancy), around 5 ppm (SMOW), is constant within error throughout the analysed crystals. In GT2, the situation is different since HREE concentrations appear remarkably constant within a given crystal and from one crystal to the other. In contrast with GT1, Na in GT2 is partly charge-balanced by yttrium incorporation. The δ18O ratio in GT2 of around 7 ppm is close to that encountered in GT3 (gneiss) between 7 and 8 ppm. In GT3, phosphorus content is close to detection limit (P_2O_5 below 300 ppm). HREE concentrations are highly variable from one crystal to the other and unfortunately, the size of garnet crystals does not allow profiling. Although δ18O ratio in garnet is imposed by the bulk-rock isotopic composition, HREE distribution is dominated by element availability through the fluid composition and/or absence/presence of accessory phases. The decrease in HREE and P concentration from GT1 cores to rims suggest that these elements are

Sensitization and activation of trigeminal nociceptors is implicated in prevalent and debilitating orofacial pain conditions including temporomandibular joint (TMJ) disorders. Orexins are excitatory neuropeptides that function to regulate many physiological processes and are reported to modulate nociception. To determine the role of orexins in an inflammatory model of trigeminal activation, the effects of a dual orexin receptor antagonist (DORA-12) on levels of proteins that promote peripheral and central sensitization and changes in nocifensive responses were investigated. In adult male Sprague-Dawley rats, mRNA for orexin receptor 1 (OX₁R) and receptor 2 (OX₂R) were detected in trigeminal ganglia and spinal trigeminal nucleus (STN). OX₁R immunoreactivity was localized primarily in neuronal cell bodies in the V3 region of the ganglion and in laminas I-II of the STN. Animals injected bilaterally with complete Freund's adjuvant (CFA) in the TMJ capsule exhibited increased expression of P-p38, P-ERK, and lba1 in trigeminal ganglia and P-ERK and lba1 in the STN at 2 days post injection. However, levels of each of these proteins in rats receiving daily oral DORA-12 were inhibited to near basal levels. Similarly, administration of DORA-12 on days 3 and 4 post CFA injection in the TMJ effectively inhibited the prolonged stimulated expression of protein kinase A, NFkB, and Iba1 in the STN on day 5 post injection. While injection of CFA mediated a nocifensive response to mechanical stimulation of the orofacial region at 2h and 3 and 5 days post injection, treatment with DORA-12 suppressed the nocifensive response on day 5. Somewhat surprisingly, nocifensive responses were again observed on day 10 post CFA stimulation in the absence of daily DORA-12 administration. Our results provide evidence that DORA-12 can inhibit CFA-induced stimulation of trigeminal sensory neurons by inhibiting expression of proteins associated with sensitization of peripheral and central

The present paper reports the distribution of finger ridge count correlations among four tribal populations from Andhra Pradesh, India viz., Dulia, Kotia, Manne Dora and Manzai Mali, and examines the intra and inter population variation. Higher correlations are recorded in left hands compared to right hands, but they are not significant. The homologous fingers exhibit a stronger correlation. In all the tribes, the correlations between right hand fingers are relatively higher among women when compared to men. Regarding inter population variation Dulia men differ significantly from the men of Manne Dora and the Manzai Mali tribes, and Kotia women also differ from the women of the Manne Dora significantly. The average correlation coefficient of the present populations is similar to other Indian populations reported earlier but lower than African and European populations.

The compilation of data banks relating to plasma disruptions is important for the design of next-step devices and tokamak reactors, as a means of establishing safe operation regimes and assessing the residual risk from such events. ASDEX has an operational history of 33509 plasma shots covering an exceptionally wide range of machine conditions: Divertor/limiter configurations; Ohmic, NBI, ICRH and LH heating; carbonization, boronization wall-conditioning, gas-puff and pellet refuelling. We have compiled a data base of the Disruptive Operationl Regimes in ASDEX (DORA), which contains the relevant information for all ASDEX-discharges and is available on tape and readable by different data bank systems for further evaluation. We first describe the criteria applied to recognize and classify disruptions and the information about them stored in the file. In a second part we use the DORA file for some sample applications of physical or engineering interest. In an appendix we give the data and format information necessary to read the DORA file.

2016-04-01

Full Text Available La poesía de Gabriela Mistral conserva numerosos rastros del lenguaje oral y parece exigir para su "performance'" la lectura comunitaria y no la de la soledad de texto y lector. En el presente trabajo se ha denominado "oralidad residual" a este fenómeno, y se intenta, como primer paso de una investigación más amplia, determinar las causas de dicho fenómeno. The poetry of Gabriela Mistral retains many traces of oral language and seems to require conmunal reading for its "performance" and not the loneliness of text and reader. This phenomenon is called "residual oralness" in this work; and an intent is made to determine the causes of the phenomenon as a first step in research.

The CanOE strategy: integrating genomic and metabolic contexts across multiple prokaryote genomes to find candidate genes for orphan enzymes.

Full Text Available Of all biochemically characterized metabolic reactions formalized by the IUBMB, over one out of four have yet to be associated with a nucleic or protein sequence, i.e. are sequence-orphan enzymatic activities. Few bioinformatics annotation tools are able to propose candidate genes for such activities by exploiting context-dependent rather than sequence-dependent data, and none are readily accessible and propose result integration across multiple genomes. Here, we present CanOE (Candidate genes for Orphan Enzymes, a four-step bioinformatics strategy that proposes ranked candidate genes for sequence-orphan enzymatic activities (or orphan enzymes for short. The first step locates "genomic metabolons", i.e. groups of co-localized genes coding proteins catalyzing reactions linked by shared metabolites, in one genome at a time. These metabolons can be particularly helpful for aiding bioanalysts to visualize relevant metabolic data. In the second step, they are used to generate candidate associations between un-annotated genes and gene-less reactions. The third step integrates these gene-reaction associations over several genomes using gene families, and summarizes the strength of family-reaction associations by several scores. In the final step, these scores are used to rank members of gene families which are proposed for metabolic reactions. These associations are of particular interest when the metabolic reaction is a sequence-orphan enzymatic activity. Our strategy found over 60,000 genomic metabolons in more than 1,000 prokaryote organisms from the MicroScope platform, generating candidate genes for many metabolic reactions, of which more than 70 distinct orphan reactions. A computational validation of the approach is discussed. Finally, we present a case study on the anaerobic allantoin degradation pathway in Escherichia coli K-12.

A computational account of the development of the generalization of shape information.

Abecassis, Sera, Yonas, and Schwade (2001) showed that young children represent shapes more metrically, and perhaps more holistically, than do older children and adults. How does a child transition from representing objects and events as undifferentiated wholes to representing them explicitly in terms of their attributes? According to RBC (Recognition-by-Components theory; Biederman, 1987), objects are represented as collections of categorical geometric parts ("geons") in particular categorical spatial relations. We propose that the transition from holistic to more categorical visual shape processing is a function of the development of geon-like representations via a process of progressive intersection discovery. We present an account of this transition in terms of DORA (Doumas, Hummel, & Sandhofer, 2008), a model of the discovery of relational concepts. We demonstrate that DORA can learn representations of single geons by comparing objects composed of multiple geons. In addition, as DORA is learning it follows the same performance trajectory as children, originally generalizing shape more metrically/holistically and eventually generalizing categorically.

2016-09-01

Full Text Available Background: Declining lung function signifies disease progression in idiopathic pulmonary fibrosis (IPF. Vascular endothelial growth factor (VEGF concentration is associated with declining lung function in 6 and 12-month studies. Alveolar nitric oxide concentration (CANO is increased in patients with IPF, however its significance is unclear. This study investigated whether baseline plasma VEGF concentration and CANO are associated with disease progression or mortality in IPF. Methods: 27 IPF patients were studied (maximum follow-up 65 months. Baseline plasma VEGF concentration, CANO and pulmonary function tests (PFTs were measured. PFTs were performed the preceding year and subsequent PFTs and data regarding mortality were collected. Disease progression was defined as one of: death, relative decrease of ≥10% in baseline forced vital capacity (FVC % predicted, or relative decrease of ≥15% in baseline single breath diffusion capacity of carbon monoxide (TLCO-SB % predicted. Results: Plasma VEGF concentration was not associated with progression-free survival or mortality. There was a trend towards shorter time to disease progression and death with higher CANO. CANO was significantly higher in patients with previous declining versus stable lung function. Conclusion: The role of VEGF in IPF remains uncertain. It may be of value to further investigate CANO in IPF.

[Doctor and poet as rivals. Sigmund Freud, Alfred von Berger and the narrative of female homosexuality].

Science.gov (United States)

Goldmann, Stefan

2011-01-01

Starting from a passage in the Dora case history where Freud suggests some differences between a literary and a clinical narrative of female homosexuality, this paper presents examples which he might have had in mind. Besides Balzac's "La fille aux yeux d'or" (1834/35) it is in particular Alfred v. Berger's novella "Die Italienerin [The Italian woman]" (1904) which may have served as a model and counterpoint to the literary strategies used in Freud's case history. Freud had a relationship of long standing with Berger. This newly discovered source may provide a clue for the date at which Freud finalized the Dora manscript which he had held back for years.

1992-01-01

In vivo 3P NMR spectroscopic study of forearm wrist flexor muscles was performed in two groups of volunteers composed respectively of 6 sedentaries and 6 canoe athletes. A continuous isometric contraction of endurance exercise was adopted in order to assess the endurance capacity and recovery potential of skeletal muscles. Differences in high energy phosphorus metabolism between the sedentaries and athletes were evaluated with and emphasis on the intracellular pH and Pi/PCr ratio as indicators of high energy phosphorus metabolism, There were no differences of baseline pH and Pi/ PCr ratio between the two groups. The athletes sustained the exercise at a more acidic intracellular pH and at a higher Pi/ PCr radio of intracellular conditions for an all out than did the sedentaries. The recovery rate of pH showed no difference between the two groups. There was a tendency of faster recovery of Pi/ PCr in athletes showing half recovery time (T 1/2 ) of 39.0 ± 3.0 seconds as compared to that of sedentaries (55.7 ± 7.5 seconds). The recovery rate of Pi/ PCr as a function of Pi/ PCr rate at a given period of time was significantly faster in athletes than in sedentaries (P<0.001). The correlation coefficient of the recovery rate of Pi/ PCr against the Pi/ PCr ratio was 0.985 and 0.914 respectively for the athletes and sedentaries. The pH and the Pi/ PCr ratio at an all-out state can be used as indicators of endurance capacity and the recovery rate of Pi/ PCr, as a recovery potential of skeletal muscles

Dual orexin receptor antagonists (DORAs) enable initiation and maintenance of sleep in patients with primary insomnia. Blockade of the orexin system has shown reduction of drug-seeking behavior in animal studies, supporting the role of orexin antagonism as a novel approach for treating substance abuse. Since hypnotics are traditionally associated with misuse, a lack of abuse liability of DORAs would offer significant benefits over current therapies for sleep disorders. In this randomized, crossover, proof-of-concept study, single oral doses of the DORA almorexant (200, 400, and 1,000 mg) were administered to healthy subjects with previous non-therapeutic experience with central nervous system depressants and were compared with placebo and single oral doses of zolpidem (20 and 40 mg), a benzodiazepine-like drug. Subjective measures of abuse potential (visual analog scales [VAS], Addiction Research Center Inventory, and Subjective Drug Value) and objective measures (divided attention [DA]) were evaluated over 24 h post-dose in 33 evaluable subjects. Drug Liking VAS peak effect (E max; primary endpoint) was significantly higher for all doses of almorexant and zolpidem compared with placebo (p<0.001). Almorexant 200 mg showed significantly less 'Drug Liking' than both zolpidem doses (p<0.01), and almorexant 400 mg had smaller effects than zolpidem 20 mg (p<0.05), while almorexant 1,000 mg was not different from either zolpidem dose. Results were similar for other subjective measures, although almorexant generally showed smaller negative and perceptual effects compared with zolpidem. Almorexant also showed less cognitive impairment compared with zolpidem on most DA endpoints. This study in humans investigating single doses of almorexant is the first to explore and show abuse liability of a DORA, a class of compounds that is not only promising for the treatment of sleep disorders, but also of addiction.

Evaluation of soil metal bioavailability estimates using two plant species (L. perenne and T. aestivum) grown in a range of agricultural soils treated with biosolids and metal salts

Black, Amanda; McLaren, Ronald G.; Reichman, Suzanne M.; Speir, Thomas W.; Condron, Leo M.

2011-01-01

Few studies have quantified the accuracy of soil metal bioavailability assays using large datasets. A meta-analysis from experiments spanning 6 months to 13 years on 12 soil types, compared bioavailability estimate efficiencies for wheat and ryegrass. Treatments included biosolids ± metals, comparing total metal, Ca(NO 3 ) 2 , EDTA, soil solution, DGT and free ion activity. The best correlations between soil metal bioavailability and shoot concentrations were for Ni using Ca(NO 3 ) 2 (r 2 = 0.72) which also provided the best estimate of Zn bioavailability (r 2 = 0.64). DGT provided the best estimate of Cd bioavailability, accounting for 49% of shoot Cd concentrations. There was no reliable descriptor of Cu bioavailability, with less than 35% of shoot Cu concentrations defined. Thus interpretation of data obtained from many soil metal bioavailability assays is unreliable and probably flawed, and there is little justification to look beyond Ca(NO 3 ) 2 for Ni and Zn, and DGT for Cd. - Highlights: → A meta-analysis evaluated the efficacy of soil metal bioavailability assays. → DGT could explain 49% of shoot Cd concentration. → There is little justification to look beyond Ca(NO 3 ) 2 for Ni and Zn. - A meta-analysis of soil metal bioavailability estimates for 12 soil types concluded that there is little justification to look beyond Ca(NO 3 ) 2 for Ni and Zn, and DGT for Cd.

2017-10-01

Full Text Available For some decades, feminist thinkers such as Luce Irigaray, Luisa Muraro and Rosi Braidotti —among others— have tried to reconstruct the ontological assumptions of a language independent of the abstract phallogocentric logic, emerging by metonymic mediation from the maternal-material-matristic substrate, in essential continuity with that origin and immediate connection with life. In the context of this new maternal-matrix-material symbolic, this article aims to read Mistralian poetics, conceived and nurtured by the same matrix from which life is born.

2006-01-01

Influence of the water content to chemical status of trivalent rare earth ions in calcium nitrate hydrate melt was studied by spectroscopic techniques. Fluorescence spectrometry for Eu(III) in Ca(NO 3 ) 2 .RH 2 O and electronic absorption spectrometry for Nd(III) in Ca(NO 3 ) 2 .RH 2 O were performed for analyzing the changing coordination symmetries through the changes in their hypersensitive transitions. Raman spectroscopic study and EXAFS study were performed for Y(NO 3 ) 3 solutions and Y(III) in Ca(NO 3 ) 2 .RH 2 O for analyzing the oxygen bonding to Y(III). Luminescence lifetime study of Eu(III) and Dy(III) in Ca(NO 3 ) 2 .RH 2 O was performed for evaluating the hydration number changes. Results of these spectroscopic studies indicated that, with the decrease of water content (R), the hydration number decreases while the interaction between trivalent rare earth ion and nitrate ion increases. It was also revealed that the symmetry of the coordination sphere gets distorted gradually by this interaction

Modiano Historien

2007-06-01

Full Text Available Beginning with the "Trilogy" ( La place de l'étoile, Ronde de nuit , and Les boulevards de ceinture of his first three novels published in the late 1960s and early 1970s, the work of Patrick Modiano has been indissociably linked with the history and memory of the Occupation. Dora Bruder is of course no exception along these lines. What makes Modiano's Occupation novels distinctive is their combination of the "historian's" knowledge of the historical realities of the period and the novelist's or "poet's" talent for powerfully evoking the feel and ambiance of "les années noires." While Modiano's practice as novelist has been widely discussed, his practice and especially his vision as "historian" deserves greater attention. This essay seeks to assess the novelist's historical vision through a reading of Dora Bruder , including the "Trilogy" and the more recent Un pedigree .

Fluorescence Quenching of Humic Acid by Coated Metallic Silver Particles.

Science.gov (United States)

Zhu, Guocheng; Yin, Jun

2017-07-01

Natural organic matter is an important component of the aquatic environments, which has attracted wide attention to its influence of interaction with other pollutants. The present work aimed to investigate its fluorescence quenching (FQ) by coated metallic silver particles (AgNPs). In this work, using fluorescence spectroscopy in conjunction with UV-Vis spectroscopy and dynamic light scattering, the effect of coated AgNPs on fluorescence quenching intensity (FQI) of humic acid (HA) was assessed. In addition, the influence of electrolytes (NaCl, NaNO 3 and CaNO 3 ) in the FQI was observed. Results showed that with AgNPs dosage increased (>1.17X10 -3  mM), fluorescence quantum yield of HA gradually decreased, which implies that the FQ occurred. Furher observation showed that the FQ process followed both first-order and second-order Stern-Volmer functions. The FQ process was affected by the electrolytes: NaCl had an effect on reduction of FQI, possibly resulting from dissolution of AgNPs; Both of NaNO 3 and Ca(NO 3 ) 2 had an effect on the FQ of HA but Ca(NO 3 ) 2 presented greater degree. As a result, the FQ degree of HA by alone electrolyte was listed in descent order as Ca(NO 3 ) 2  > NaNO 3  > NaCl, which also implies the subsequent experimental results, indicating the FQ degree of HA by mutual electrolytes as Ca(NO 3 ) 2  + NaNO 3  > Ca(NO 3 ) 2  + NaCl > NaNO 3  + NaCl.

Smirnov, P.M.; Pedishyus, R.K.

1974-01-01

Effects of aerobic and anaerobic conditions; pH, and soil sterilization on the nitrogen loss from ( 15 NH 4 ) 2 SO 4 , Ca( 15 NO 3 ) 2 and Na 15 NO 2 have been studied in vitro. Composition of the liberated gases has been determined by the adsorption chromatography technique. Gaseous losses of fertilizer nitrogen are shown to proceed most intensely during first 10 to 30 days after nitrogen application, Ca(NO 3 ) 2 nitrogen loss being much higher than that of (NH 4 ) 2 SO 4 . Under anaerobic conditions nitrogen losses are markedly higher than in the presence of oxygen. Nitrogen of Ca(NO 3 ) 2 and (NH 4 ) 2 SO 4 is lost mainly as N 2 O and N 2 , the proportion of NO and NO 2 under aerobic and, particularly, anaerobic conditions is very small. Fertilizer type and aeration affect strongly the composition of liberated gases and the N 2 O:N 2 ratio. Under anaerobic conditions, Ca(NO 3 ) 2 nitrogen, beginning from the first days, is lost mainly as N 2 (75-80%), N 2 O makes up only 12 to 14%. Under aerobic conditions, (NH 4 ) 2 SO 4 and Ca(NO 3 ) 2 release initially a considerable amount of N 2 O, its reduction to N 2 being inhibited. In the course of time, however, a noticeable growth of the N 2 fraction occurs and it is accompanied by the decrease in N 2 O. Soil pH effects are related mainly to the composition of gases released rather than to the total nitrogen loss by Ca(NO 3 ) 2 . Under anaerobic conditions, more reduced gaseous products N 2 O and N 2 - are formed at acidic and neutral soil reaction, the amount of N 2 being greater at pH 7 than at pH 4.4. Under aerobic conditions, Ca(NO 3 ) 2 at pH 7 loses nitrogen mostly as N 2 , while under acidic soil reaction (pH 4.1-4.4) the losses occur as N 2 O and in part as NO and NO 2 . Sterilized soil at acidic pH liberates primarily nitrogen oxide which is formed apparently as a result of chemical reactions with participation of nitrites

Leaching of Copper and Zinc in a Garden Soil Receiving Poultry and Livestock Manures from Intensive Farming

Institute of Scientific and Technical Information of China (English)

2008-01-01

The leaching characteristics of a garden soil may be greatly affected by application of poultry and livestock manures from intensive farming.Packed soil columns of a garden soil(CK)and the soils after respectively receiving 2% pig manure (PM),chicken manure(CM),and commercial organic manure(OM)were leached with 0.05 mol L-1 Ca(NO3)2 and 0.01 mol L-1 EDTA solutions.The leachate EC(electric conductivity)values gradually increased at the beginning and then reached a stable value when the soil columns were leached with 0.05 mol L-1 Ca(NO3)2 solution.The leachate EC values showed a peak-shape when leached with 0.01 mol L-1 EDTA solution.In all the soil columns,the pH values of the leachates decreased with increase of displacement volumes when the Ca(NO3)2 solution was used.The total amounts of Cu and Zn eluted from the four soil columns were significantly correlated with the extracted soil Cu and Zn concentrations by 1.0 mol L-1 NH4NO3,but were not correlated with the leachate dissolved organic carbon(DOC)contents.The Zn concentration in the leachate of the PM-treated soil column with 0.05 mol L-1 Ca(NO3)2 solution was above the Quality Standard III for Ground Water of China(GB/T 14848-93,Zn ＜ 1.0 mg L-1).When compared with 0.05 mol L-1 Ca(NO3)2,the EDTA solution significantly accelerated Cu and Zn elutions in the manure-treated columns.This suggested that applying poultry and livestock manures from intensive farming to farmland might pose a threat to the groundwater quality.

I defend that despite all odds, Feminism still stands as a fundamental "counter-diction," a much needed oppositional discourse in our day and age.

Distinct effects of IPSU and suvorexant on mouse sleep architecture

2013-12-01

Full Text Available Dual orexin receptor (OXR antagonists (DORAs such as almorexant, SB-649868, suvorexant (MK-4305 and filorexant (MK-6096, have shown promise for the treatment of insomnias and sleep disorders. Whether antagonism of both OX1R and OX2R is necessary for sleep induction has been a matter of some debate. Experiments using knockout mice suggest that it may be sufficient to antagonize only OX2R. The recent identification of an orally bioavailable, brain penetrant OX2R preferring antagonist 2-((1H-Indol-3-ylmethyl-9-(4-methoxypyrimidin-2-yl-2,9-diazaspiro[5.5]undecan-1-one (IPSU has allowed us to test whether selective antagonism of OX2R may also be a viable strategy for induction of sleep. We previously demonstrated that IPSU and suvorexant increase sleep when dosed during the mouse active phase (lights off; IPSU inducing sleep primarily by increasing NREM sleep, suvorexant primarily by increasing REM sleep. Here, our goal was to determine whether suvorexant and IPSU affect sleep architecture independently of overall sleep induction. We therefore tested suvorexant (25 mg/kg and IPSU (50 mg/kg in mice during the inactive phase (lights on when sleep is naturally more prevalent and when orexin levels are normally low. Whereas IPSU was devoid of effects on the time spent in NREM or REM, suvorexant substantially disturbed the sleep architecture by selectively increasing REM during the first 4 hours after dosing. At the doses tested, suvorexant significantly decreased wake only during the first hour and IPSU did not affect wake time. These data suggest that OX2R preferring antagonists may have a reduced tendency for perturbing NREM/REM architecture in comparison with DORAs. Whether this effect will prove to be a general feature of OX2R antagonists versus DORAs remains to be seen.

2012-05-01

Taking 4 different Cucurbita maxima x C. moschata rootstocks for cucumber (Cucumis sativus) as test materials, a solution culture experiment was conducted to study their growth and antioxidative enzyme activities under the stresses of Ca(NO3)2 and NaCl, with the salt stress tolerance of the rootstocks evaluated by subordinate function. At 30 mmol x L(-1) of Ca (NO3)2 or 45 mmol x L(-1) of NaCl, the growth of the rootstock seedlings was improved; but at 60 and 120 mmol x L(-1) of Ca(NO3)2 or 90 and 180 mmol x L(-1) of NaCl, the growth and the antioxidative systems of the seedlings were inhibited, and the salt injury index of 'Qingzhen No. 1' was the smallest, with the decrement of biomass and SOD, POD and CAT activities and the increment of relative conductance being significantly lower than those of the others. Under the stress of high concentration Ca(NO3)2, the SOD, POD and CAT activities of test rootstocks were higher, and the salt injury index and relative conductance were lower, as compared with those under high concentration NaCl, suggesting that the damage of Ca(NO3)2 stress to cucumber-grafted rootstock were smaller than that of NaCl stress. Among the 4 rootstocks, 'Qingzhen No. 1' had the strongest salt stress tolerance, followed by 'Zuomu Nangua', 'Fengyuan Tiejia', and 'Chaoba Nangua'.

Determination of equilibrium humidities using temperature and humidity controlled X-ray diffraction (RH-XRD)

International Nuclear Information System (INIS)

Linnow, Kirsten; Steiger, Michael

2007-01-01

Confined growth of crystals in porous building materials is generally considered to be a major cause of damage. We report on the use of X-ray diffraction under controlled conditions of temperature and relative humidity (RH-XRD) for the investigation of potentially deleterious phase transition reactions. An improved procedure based on rate measurements is used for the accurate and reproducible determination of equilibrium humidities of deliquescence and hydration reactions. The deliquescence humidities of NaCl (75.4 ± 0.5% RH) and Ca(NO 3 ) 2 .4H 2 O (50.8 ± 0.7% RH) at 25 deg. C determined with this improved RH-XRD technique are in excellent agreement with available literature data. Measurement of the hydration of anhydrous Ca(NO 3 ) 2 to form Ca(NO 3 ) 2 .2H 2 O revealed an equilibrium humidity of 10.2 ± 0.3%, which is also in reasonable agreement with available data. In conclusion, dynamic X-ray diffraction measurements are an appropriate method for the accurate and precise determination of equilibrium humidities with a number of interesting future applications

ON THE WRITING OF ARDENT THEMES: WEDDING IN A GENRE CONFLUENCE

Maria Cecília Rogers Paranhos

2011-04-01

Full Text Available This study will involve the Ardente texto Joshua (1998, from Maria Gabriela Llansol, that brings the figure of Teresa Martin, or Saint Therese of Jesus. It does not focus on her biography or the history of her scriptures, but on capturing knowledge and admiration in order to confront the “amorous art of living” with the aspiration of the ardent text: “the necessity of the body’s resuscitation”, establishing a close relation of changes and of confluences in different plans. From this text, a discussion about this scripture, that abolishes the paradigms already established and creates a new literary doing of our contemporary time, will be brought up.  With the support of the lectures of Roland Barthes, Michel Foucault, Giorgio Agamben and Gilles Deleuze, among others, it’ll be evidenced the author’s absence in this text of Llansol and its expression through a possible combination of flows. Not only ignoring the form of the diary writing, the author will also create the fiction of the diary of a writing - equally subverted, following Blanchot’s concepts. Moving away from the rigid form of the representative novel, the text of Maria Gabriela Llansol approaches to a “stutter” in its own language, that brings oscillation to the limits up to now considered between poetry and prose.

The development and application of dynamic operational risk assessment in oil/gas and chemical process industry

International Nuclear Information System (INIS)

Yang Xiaole; Mannan, M. Sam

2010-01-01

A methodology of dynamic operational risk assessment (DORA) is proposed for operational risk analysis in oil/gas and chemical industries. The methodology is introduced comprehensively starting from the conceptual framework design to mathematical modeling and to decision making based on cost-benefit analysis. The probabilistic modeling part of DORA integrates stochastic modeling and process dynamics modeling to evaluate operational risk. The stochastic system-state trajectory is modeled according to the abnormal behavior or failure of each component. For each of the possible system-state trajectories, a process dynamics evaluation is carried out to check whether process variables, e.g., level, flow rate, temperature, pressure, or chemical concentration, remain in their desirable regions. Component testing/inspection intervals and repair times are critical parameters to define the system-state configuration, and play an important role for evaluating the probability of operational failure. This methodology not only provides a framework to evaluate the dynamic operational risk in oil/gas and chemical industries, but also guides the process design and further optimization. To illustrate the probabilistic study, we present a case-study of a level control in an oil/gas separator at an offshore plant.

Modiano and Sebald: Walking in Another's Footsteps

Steven Ungar

2007-06-01

Full Text Available This article studies Patrick Modiano's Dora Bruder (1997 and W.G. Sebald's Austerlitz (2000 in conjunction with a contemporary literature of diaspora grounded in the extended aftermath of World War II. Both texts straddle fiction and testimonial accounts such as memoirs, letters, and video/audio recordings. In addition, both raise questions with which traditional historians seldom contend, even when they group these questions under the category of memory. What understanding of the recent past might these two narratives promote? What do they imply—individually or as a set—concerning the nature and function of the historical subjectivity that literature can convey? Each in its own way, Dora Bruder and Austerlitz override conventions of literary genre by mixing elements of novel, autobiography, and essay. Accordingly, language becomes a prime point of inquiry in conjunction with the double question most likely to be raised in terms of the historical record: who is writing and to what end or purpose? These questions, in turn, direct inquiry to enunciation and point of view as components of historical subjectivity associated with the literature of a post-World War II diaspora.

Study of the influence of the metal partition coefficient on the human health risk evaluation, applied to Figueira (PR) soil region, using C-Soil model

International Nuclear Information System (INIS)

Camargo, Iara Maria Carneiro de.

2005-01-01

Studies of partition coefficient show that Kp values of metals can vary orders of magnitude according to the soil physical-chemistry characteristics. Therefore, the Kp is a sensible parameter in human health risk assessment model. In general, a default value is adopted by environmental agencies and often it is not represent suitably the soil studied and can cause errors in the risk calculation. The objectives of this work are: evaluate the heavy metals soil contamination around the Figueira coal-fired power plant; determine the metal Kp of As, Cd, Co, Cr, Cu, Mo, Ni, Pb and Zn in soil by the ratio between the metal concentration obtained by concentrate HNO 3 digestion and the metal concentration obtained by extraction with EDTA 0,05 mol L -1 (Kp EDTA ) or Ca(NO 3 ) 2 0,1 mol L -1 (Kp Ca(NO3)2 ); and evaluate the influence of the application of different Kp values in human health risk assessment C-Soil model in risk calculation. The main conclusions of the present study were: As, Cd, Mo, Pb e Zn were the Figueira soil metal contaminants, being As the pollutant of major human health concern; either Kp Ca(NO3)2 or Kp EDTA values could be used for human health risk calculation, in Figueira case, except for Pb, and the Kp EDTA values were preferably recommended due to the less dispersion of their values; the KpC Soil metals default values could be applied for the human health risk calculation in Figueira case, in other words, it would not have necessity to determine Kp values of region (Kp EDTA and Kp Ca(NO3)2 ), except to Pb.

Full Text Available On the southwest Pacific Coast of Colombia, a field study was initiated to determine the human-vector association between Anopheles (Kerteszia neivai and fishermen, including their nearby houses. Mosquitoes were collected over 24-h periods from mangrove swamps, marshlands and fishing vessels in three locations, as well as in and around the houses of fishermen. A total of 6,382 mosquitoes were collected. An. neivai was most abundant in mangroves and fishing canoes (90.8%, while Anopheles albimanus was found indoors (82% and outdoors (73%. One An. neivai and one An. albimanus collected during fishing activities in canoes were positive for Plasmodium vivax , whereas one female An. neivai collected in a mangrove was positive for P. vivax . In the mangroves and fishing canoes, An. neivai demonstrated biting activity throughout the day, peaking between 06:00 pm-07:00 pm and there were two minor peaks at dusk and dawn. These peaks coincided with fishing activities in the marshlands and mangroves, a situation that places the fishermen at risk of contracting malaria when they are performing their daily activities. It is recommended that protective measures be implemented to reduce the risk that fishermen will contract malaria.

Enteric viruses in a mangrove lagoon, survival and shellfish incidence

Energy Technology Data Exchange (ETDEWEB)

Lopez de Cardona, I.; Bermudez, M.; Billmire, E.; Hazen, T.C. [Univ. of Puerto Rico, Rio Piedras (Puerto Rico)

1988-12-31

Mangrove oysters (Crassostrea rhizophorae) were screened for enteric viruses. For 18 months oysters were collected from Cano Boqueron, a tropical mangrove lagoon on the southwest coast of Puerto Rico. This popular tourist resort has two primary sewage treatment plants which service 158 single family cabanas. In spite of the heavy seasonal input of sewage to Cano Boqueron and high densities of fecal coliform bacteria, enteric viruses were not detected in shellfish meat. Because no viruses were detected in the oysters, a virus survival study was performed. Poliovirus type 1 was placed in diffusion chambers in situ at two sites in Cano Boqueron. More than 95% of the poliovirus inactivation occurred within 24 h. Virus inactivation was significantly different by site, indicating different inactivation rates within the lagoon. Chamber studies done simultaneously with Escherichia coli did not reveal differences between sites. It is suggested that the sewage effluent had an antiviral effect in the absence of an antibacterial effect. This study demonstrates the importance for establishing microbial contamination standards for shellfish growing waters in the tropics based upon in situ studies with tropical species, e.g. mangrove oyster.

Preparation of CaO/Fly ash as a catalyst inhibitor for transesterification process off palm oil in biodiesel production

Science.gov (United States)

Helwani, Z.; Fatra, W.; Saputra, E.; Maulana, R.

2018-03-01

A palm fly ash supported calcium oxide (CaO) catalyst was prepared and used in transesterification from off-grade palm oil for biodiesel production. The catalyst synthesized by loading CaO of calcium nitrate tetrahydrate (Ca(NO3)2.4H2O) into fly ash through impregnation method. The optimum catalyst preparation conditions were determined by influence of calcination temperature and weight ratio of Ca(NO3)2.4H2O and fly ash. Catalyst with highest catalytic activity was achieved when calcined at 800 °C and proportion of Ca(NO3)2.4H2O to fly ash is 80:20. Under the conditions of oil : methanol ratio of 1:6, catalyst dosage of 6 wt% and temperature of 70 °C for 2 h, the biodiesel yield reaches to 71.77%. CaO, SiO2, Ca(OH)2 and Ca2SiO4 were found in the catalyst through X-ray diffraction (XRD) while the basic strength of the catalyst H_ in the range 9.3 – 11. Surface area of the developed catalyst is 24.342 m2/g through Brunauer-Emmett-Teller (BET). Characteristics of biodiesel such as density, kinematic viscosity, acid value, flash point has been matched with standard for biodiesel specification of Indonesia.

Public Opinion and frames: crisis of the dugout canoes

Directory of Open Access Journals (Sweden)

Dra. Raquel Rodríguez Díaz

2008-01-01

Full Text Available According to public opinion the increasing number of foreign population has became one of the most problematic issues in the last decade. Since 2005 immigration is the second biggest concern for Spaniards after unemployment and followed by terrorism. It is has became a state issue and a central government worry of utmost importance. The media coverage given to immigration is very important, specifically the way in which it is approached and presented to the readers. This paper shows the different perspectives or frames used by two key nationwide Spanish newspapers, El País y El Mundo, to cover one of the migration crises that took place in the Canary Islands in spring 2006. Following Framing theory, media content has been analyzed using variables to show the different ways in which these media depict the phenomenon of migration and the approach which each newspaper follows.

Nitrate salts suppress sporulation and production of enterotoxin in Clostridium perfringens strain NCTC8239.

Yasugi, Mayo; Otsuka, Keisuke; Miyake, Masami

2016-10-01

Clostridium perfringens type A is a common source of food-borne illness in humans. Ingested vegetative cells sporulate in the small intestinal tract and in the process produce C. perfringens enterotoxin (CPE). Although sporulation plays a critical role in the pathogenesis of food-borne illness, the molecules triggering/inhibiting sporulation are still largely unknown. It has previously been reported by our group that sporulation is induced in C. perfringens strain NCTC8239 co-cultured with Caco-2 cells in Dulbecco's Modified Eagle Medium (DMEM). In contrast, an equivalent amount of spores was not observed when bacteria were co-cultured in Roswell Park Memorial Institute-1640 medium (RPMI). In the present study it was found that, when these two media are mixed, RPMI inhibits sporulation and CPE production induced in DMEM. When a component of RPMI was added to DMEM, it was found that calcium nitrate (Ca[NO 3 ] 2 ) significantly inhibits sporulation and CPE production. The number of spores increased when Ca(NO 3 ) 2 -deficient RPMI was used. The other nitrate salts significantly suppressed sporulation, whereas the calcium salts used did not. qPCR revealed that nitrate salts increased expression of bacterial nitrate/nitrite reductase. Furthermore, it was found that nitrite and nitric oxide suppress sporulation. In the sporulation stages, Ca(NO 3 ) 2 down-regulated the genes controlled by Spo0A, a master regulator of sporulation, but not spo0A itself. Collectively, these results indicate that nitrate salts suppress sporulation and CPE production by down-regulating Spo0A-regulated genes in C. perfringens strain NCTC8239. Nitrate reduction may be associated with inhibition of sporulation. © 2016 The Societies and John Wiley & Sons Australia, Ltd.

Calcium Solubility and Cation Exchange Properties in Zeoponic Soil

Science.gov (United States)

Beiersdorfer, Raymond E.

1999-01-01

An important aspect of a regenerative life support system at a Lunar or Martian outpost is the ability to produce food. Essential plant nutrients, as well as a solid support substrate, can be provided by: (1) treated Lunar or Martian regolith; (2) a synthetic soil or (3) some combination of both. A synthetic soil composed of ammonium- and potassium-saturated chinoptlolite (a zeolite mineral) and apatite, can provide slow-release fertilization of plants via dissolution and ion-exchange reactions. Previous equilibrium studies (Beiersdorfer, 1997) on mixtures of synthetic hydroxyapatite and saturated-clinoptilolite indicate that the concentrations of macro-nutrients such as ammonium, phosphorous, potassium, magnesium, and calcium are a function of the ratio of chinoptilolite to apatite in the sample and to the ratio of potassium to ammonium on the exchange sites in the clinoptilolite. Potassium, ammonium, phosphorous, and magnesium are available to plants at sufficient levels. However, calcium is deficient, due to the high degree of calcium adsorption by the clinoptilolite. Based on a series of batch-equilibration experiments, this calcium deficiency can be reduced by (1) treating the clinoptilolite with CaNO3 or (2) adding a second Ca-bearing mineral (calcite, dolomite or wollastonite) to the soil. Treating the Cp with CaNO3 results in increased Ca in solution, decreased P in solution and decreased NH4 in solution. Concentrations of K were not effected by the CaNO3 treatment. Additions of Cal, Dol and Wol changed the concentrations of Ca and P in solution in a systematic fashion. Cal has the greatest effect, Dol the least and Wol is intermediate. The changes are consistent with changes expected for a common ion effect with Ca. Higher concentrations of Ca in solution with added Cal, Dol or Wol do not result in changes in K or NH4 concentrations.

The racing dragon

CERN Multimedia

2009-01-01

Dating back nearly 2000 years, the ancient Chinese tradition of Dragon Boat Racing was originally a celebration that fell on the 5th day of the 5th lunar month as a gesture to please the Gods and bring forth necessary rains to cultivate the lands. Now the CERN Canoe and Kayak Club, too, participates in this tradition, though not so much to please the Gods on the ritualistic date, but to bring forth giant smiles on the faces of members. Dragon Boat Racing has been rising steadily in popularity in Europe since the mid nineties and with the great potential to host and promote Dragon Boat Racing in the Geneva area, the CERN Canoe and Kayak Club, has taken the initiative to bring the sport to the region. Some members of the Club traveled to Dole in June to participate in the Festival Dragon Boat 2009. Under perfect sunny conditions, the team triumphed in their first ever tournament, cruising to a convincing first place overall finish. T...

The Nu Women

1998-01-01

In the northwest of Yunnan Province lies an area of 14,703 square kilometers called Nujiang Lisu Autonomous Prefecture, which is inhabited by an ethnic group unique to Yunnan—the Nu ethnicity. The Nu people are the most ancient settlers and the earliest pioneers of the region. With a population of 27, 123(13,000 females), the Nu are among the smallest of China’s 55 ethnic groups. The Nu live in a mountainous area filled with sloping hills and steep cliffs. The roaring Nujiang River and Lacangjiang River separate the Nu from the outside world. In addition to using rope bridges, the Nu cross the rivers bv means of dugout canoes. The canoes are so small that it is hard to imagine they can be rowed in the rolling waves, but the Nu are good ferrymen. Some people believe that the changeable weather and the complicated natural environment nurtures the Nu to develop rugged and straightforward personalities. The Nu are an optimistic people who take delight in their life. The men like to play the musical instrument k

Effects of a newly developed potent orexin-2 receptor-selective antagonist Compound1m on sleep/wake states in mice

Directory of Open Access Journals (Sweden)

Keishi eEtori

2014-01-01

Full Text Available Orexins (also known as hypocretins, which are hypothalamic neuropeptides, play critical roles in the regulation of sleep/wakefulness states by activating two G-protein coupled receptors (GPCRs, orexin 1 (OX1R and orexin 2 receptors (OX2R. In order to know the difference between effects of OX2R-selective antagonists (2-SORA and dual orexin receptor antagonists (DORA, and to understand the mechanisms underlying orexin-mediated regulation of sleep/wakefulness states, we examined the effects of a newly developed 2-SORA, Compound 1m (C1m, and a DORA, suvorexant, on sleep/wakefulness states in C57BL/6J mice. After oral administration in the dark period, both C1m and suvorexant exhibited potent sleep-promoting properties with similar efficacy in a dose-dependent manner. While C1m did not increase NREM and REM sleep episode durations, suvorexant induced longer episode durations of NREM and REM sleep as compared with both the vehicle- and C1m-administered groups. When compounds were injected during light period, C1m did not show a significant change in sleep/wakefulness states in the light period, whereas suvorexant slightly but significantly increased the sleep time. We also found that C1m did not affect the time of REM sleep, while suvorexant markedly increased it. This suggests that although OX1R-mediated pathway plays a pivotal role in promoting wakefulness, OX1R-mediated pathway also plays an additional role. OX1R-mediated pathway also plays a role in suppression of REM sleep. Fos-immunostaining showed that both compounds affected the activity of arousal-related neurons with different patterns. These results suggest partly overlapping and partly distinct roles of orexin receptors in the regulation of sleep/wakefulness states.

OREXIN 1 AND 2 RECEPTOR INVOLVEMENT IN CO2-INDUCED PANIC-ASSOCIATED BEHAVIOR AND AUTONOMIC RESPONSES

Science.gov (United States)

Johnson, Philip L.; Federici, Lauren M.; Fitz, Stephanie D.; Renger, John J.; Shireman, Brock; Winrow, Christopher J.; Bonaventure, Pascal; Shekhar, Anantha

Background The neuropeptides orexin A and B play a role in reward and feeding and are critical for arousal. However, it was not initially appreciated that most prepro-orexin synthesizing neurons are almost exclusively concentrated in the perifornical hypothalamus, which when stimulated elicits panic-associated behavior and cardiovascular responses in rodents and self-reported “panic attacks” and “fear of dying” in humans. More recent studies support a role for the orexin system in coordinating an integrative stress response. For instance, orexin neurons are highly reactive to anxiogenic stimuli, are hyperactive in anxiety pathology, and have strong projections to anxiety and panic-associated circuitry. Although the two cognate orexin receptors are colocalized in many brain regions, the orexin 2 receptor (OX2R) most robustly maps to the histaminergic wake-promoting region, while the orexin 1 receptor (OX1R) distribution is more exclusive and dense in anxiety and panic circuitry regions, such as the locus ceruleus. Overall, this suggests that OX1Rs play a critical role in mobilizing anxiety and panic responses. Methods Here, we used a CO2-panic provocation model to screen a dual OX1/2R antagonist (DORA-12) to globally inhibit orexin activity, then a highly selective OX1R antagonist (SORA1, Compound 56) or OX2R antagonist (SORA2, JnJ10397049) to assess OX1R and OX2R involvement. Results All compounds except the SORA2 attenuated CO2-induced anxiety-like behaviors, and all but the SORA2 and DORA attenuated CO2-induced cardiovascular responses. Conclusions SORA1s may represent a novel method of treating anxiety disorders, with no apparent sedative effects that were present with a benzodiazepine. PMID:26332431

Ces textes déploient une pratique intertextuelle critique à l’égard des manières de donner sens à l’être et à l’agir qui mettent en relation signifiante l’individu et des catégories sociales ou culturelles, moyennant configurations narratives centripètes et sentiments ou émotions courants. Ils élaborent en réaction conception de l’être humain, grammaire des affects et poétique narrative susceptibles de représenter des états psychologiques culturellement insolites sinon inconnus (sentiment de vacance et d’éternité, sensation de familiarité rompue. On suggère ainsi un lien constitutif entre conception de l’être humain – c’est-à-dire anthropologie – et poétique narrative. This article analyses the anthropological implications of Modiano’s Dora Bruder, Chauvier’s Anthropologie and Léger’s Supplément à la vie de Barbara Loden. These texts implement a critical intertextual practice with respect to the means of attributing meaning to being and acting that relate the individual to social or cultural categories, effecting centripetal narrative configurations and common feelings or emotions. As a result, they produce a conception of the human being, a grammar of human affect and a narrative poetics susceptible to representing psychological states that are culturally unusual if not unknown (feelings of vacancy or eternity, sensations of broken familiarity. We therefore suggest a constitutive link between the conception of the human being – that is to say anthropology – and narrative poetics.

The illusion of parental celibacy. A necessary stage in adolescent development.

Science.gov (United States)

Shopper, Moisy

2002-01-01

The paper begins by reviewing Freud's case history of Dora and emphasizing her involvement in and overstimulation by her parents' sexual behavior. This markedly interfered with her ability to desexualize her relationship with them. As a result she was unable to develop the illusion of parental celibacy, which I postulate is an important and necessary defensive stage in normal adolescence. This illusion facilitates the desexualization of the adolescent's relationship to the parents and so contributes to separation from them and the seeking of non-incestuous sexual outlets. The disruption of this illusion of parental celibacy by parental sex education, or by the complications of parental divorce may contribute significantly to the development of adolescent psychopathology. Clinical vignettes are presented.

You can’t change what you can’t measure: Understanding greenhouse gas emissions in Costa Rica

International Nuclear Information System (INIS)

Madsen, Michael Amdi

2015-01-01

In Costa Rica climate change is a real concern. Sea level rise, climatic variability, and climate-induced disease outbreaks are likely to affect the availability of drinking water and threaten local amphibians and marine life. The country is committed to reducing its greenhouse gas emissions, and is now taking steps to learn how much greenhouse gases the dairy and agricultural sectors emit in order to determine what actions it can take to reduce the impact of climate change. “A lack of training, equipment and national laboratory mean that Cost Rica relies on international emission factors to estimate the emissions of greenhouse gases from agriculture,” said Ana Gabriela Pérez, a researcher at the University of Costa Rica, who is working to develop a national reference laboratory for the measurement of greenhouse gases in the country.

Emerging role of orexin antagonists in insomnia therapeutics: An update on SORAs and DORAs.

Science.gov (United States)

Kumar, Anil; Chanana, Priyanka; Choudhary, Supriti

2016-04-01

The pharmacological management of insomnia has lately become a challenge for researchers worldwide. As per the third International Classification of Sleep disorders (ICSD-3) insomnia can be defined as a state with repeated difficulty in sleep initiation, duration, consolidation, or quality that occurs despite adequate opportunity and circumstances for sleep, and results in some form of daytime impairment. The conventional treatments approved for management of insomnia were benzodiazepines (BZDs) (estazolam, quazepam, triazolam, flurazepam and temazepam) and non-BZDs, also known as z-drugs (zaleplon, zolpidem, and eszopiclone), tricyclic antidepressant (TCA) doxepin as well as melatonin agonists, e.g. ramelteon. But the potential of these agents to address sleep problems has been limited due to substantial side effects associated with them like hangover, dependence and tolerance, rebound insomnia, muscular atonia, inhibition of respiratory system, cognitive dysfunctions, and increased anxiety. Recently, orexin neuropeptides have been identified as regulators of transition between wakefulness and sleep and documented to aid an initial transitory effect towards wakefulness by activating cholinergic/monoaminergic neural pathways of the ascending arousal system. This has led to the development of orexin peptides and receptors, as possible therapeutic targets for the treatment of sleep disorders with the advantage of having lesser side effects as compared to conventional treatments. The present review focuses on the orexin peptides and receptors signifying their physiological profile as well as the development of orexin receptor antagonists as novel strategies in sleep medicine.

The scientific foundation for the criticism on the use of the Journal Impact Factor (JIF) in evaluations of individual researchers and their publications was laid between 1989 and 1997 in a series of articles by Per O. Seglen. His basic work has since influenced initiatives such as the San Francisco Declaration on Research Assessment (DORA), the Leiden Manifesto for research metrics, and The Metric Tide review on the role of metrics in research assessment and management. Seglen studied the publications of only 16 senior biomedical scientists. We investigate whether Seglen's main findings still hold when using the same methods for a much larger group of Norwegian biomedical scientists with more than 18,000 publications.

Full Text Available Palisade grass is a forage plant that is widely used in pasture cropping in the Brazilian savannah. The aim of this experiment was to evaluate palisade grass (Brachiaria brizantha cv. MG–5 seeds subjected to priming and stress at high humidity and temperature (before and after conditioning. The experimental design was completely randomized in a 2x5 factorial arrangement. Seeds were exposed to stress under high humidity and temperature (before and after conditioning and five priming treatments [Water (Control, potassium nitrate (KNO3 at 0.2%, calcium nitrate Ca(NO32 at 0.2%, gibberellin (GA3 at 0.2% and glucose at 10%] with four replications. Two experiments were performed: Experiment I - seed with chemical scarification using H2SO4 and Experiment II - without scarification. The stress on the seed was applied using artificial aging at 41°C for 96 hours. Seed priming was accomplished by immersion at 25°C for 2 hours. Thereafter, the seeds were oven-dried at 35°C until they regained hygroscopic equilibrium. Seed germination and vigor were evaluated. Priming using KNO3 and Ca(NO32 produced seeds with high tolerance to stress under high temperature, and this process is efficient to overcome dormancy.

The manufacturing of tooling for large, contoured surfaces for fiber-layup applications requires significant effort to understand the geometry and then to subtractively manufacture the tool. Traditional methods for the auto industry use clay that is hand sculpted. In the marine pleasure craft industry, the exterior of the model is formed from a foam lay-up that is either hand cut or machined to create smooth lines. Engineers and researchers at Oak Ridge National Laboratory s Manufacturing Demonstration Facility (ORNL MDF) collaborated with Magnum Venus Products (MVP) in the development of a process for reproducing legacy whitewater adventure craft via digital scanning and large scale 3-D printed layup molds. The process entailed 3D scanning a legacy canoe form, converting that form to a CAD model, additively manufacturing (3-D Print) the mold tool, and subtractively finishing the mold s transfer surfaces. Future work will include applying a gelcoat to the mold transfer surface and infusing using vacuum assisted resin transfer molding, or VARTM principles, to create a watertight vessel. The outlined steps were performed on a specific canoe geometry found by MVP s principal participant. The intent of utilizing this geometry is to develop an energy efficient and marketable process for replicating complex shapes, specifically focusing on this particular watercraft, and provide a finished product for demonstration to the composites industry. The culminating part produced through this agreement has been slated for public presentation and potential demonstration at the 2016 CAMX (Composites and Advanced Materials eXpo) exposition in Anaheim, CA. Phase I of this collaborative research and development agreement (MDF-15-68) was conducted under CRADA NFE-15-05575 and was initiated on May 7, 2015, with an introduction to the MVP product line, and concluded in March of 2016 with the printing of and processing of a canoe mold.

The promotion effect of coexisting hygroscopic composition on the reaction between oxalic acid and calcite during humidifying process

Science.gov (United States)

Ma, Q.; He, H.

2012-12-01

Internally mixed oxalic acid with mineral dust has been frequently detected in field measurements (Sullivan and Prather, 2007; Wang et al., 2012; Yang et al., 2009). Meanwhile, Furukawa and Takahashi (Furukawa and Takahashi, 2011) found that most of the oxalic acid in mineral mixture is present as metal oxalate complexes in the aerosols, however, the formation mechanism of these complexes is not well known. It was reported that cloud process of H2C2O4/CaCO3 mixture could lead to the formation of calcium oxalate (Gierlus et al., 2012). Recently, we used Raman spectroscopy to investigate the hygroscopic behavior of H2C2O4/CaCO3 mixture below saturation condition as well as the effect of coexisting hygroscopic compositions, e.g. Ca(NO3)2, NaCl, NH4NO3, and (NH4)2SO4. It was found that there was no interaction between H2C2O4 and calcite without third component during humidifying process under ambient condition. In contrast, the presence of coexisting Ca(NO)3, NaCl, or NH4NO3 could promote the reaction between H2C2O4 and calcite by providing an aqueous circumstance after deliquescence, resulting in the formation of calcium oxalate hydrates. Moreover, substitution of strong acid (HNO3) by medium acid (H2C2O4) occurred when water vapor was absorbed in Ca(NO3)2/H2C2O4 mixture (Ma and He, 2012). As for (NH4)2SO4, there existed a competition effect between (NH4)2SO4 and H2C2O4 for the reaction with CaCO3. CaCO3 was preferentially reacted with (NH4)2SO4 to form gypsum in the solution, while the residual NH4+ and C2O42- ions were bonded to (NH4)2C2O4 after efflorescence. These results implies a potential formation pathway of metal oxalate complexes in the atmosphere and also suggests that synergistic effect between different constituents in humidifying process of mixed particles should be considered in future hygroscopic behavior studies.

Orexin in sleep, addiction and more: is the perfect insomnia drug at hand?

Science.gov (United States)

Hoyer, Daniel; Jacobson, Laura H

2013-12-01

Orexins A and B (hypocretins 1 and 2) and their two receptors (OX1R and OX2R) were discovered in 1998 by two different groups. Orexin A and B are derived from the differential processing of a common precursor, the prepro-orexin peptide. The neuropeptides are expressed in a few thousand cells located in the lateral hypothalamus (LH), but their projections and receptor distribution are widespread throughout the brain. Remarkably, prepro peptide and double (OX1R/OX2R) receptor knock out (KO) mice reproduce a sleep phenotype known in humans and dogs as narcolepsy/cataplexy. In humans, this disease is characterized by the absence of orexin producing cells in the LH, and severely depleted levels of orexin the cerebrospinal fluid. Null mutation of the individual OX1R or OX2R in mice substantially ameliorates the narcolepsy/cataplexy phenotype compared to the OX1R/OX2R KO, and highlights specific roles of the individual receptors in sleep architecture, the OX1R KO demonstrating an a attenuated sleep phenotype relative to the OX2R KO. It has therefore been suggested that orexin is a master regulator of the sleep-wake cycle, with high activity of the LH orexin cells during wake and almost none during sleep. Less than 10years later, the first orexin antagonist, almorexant, a dual orexin receptor antagonist (DORA), was reported to be effective in inducing sleep in volunteers and insomnia patients. Although development was stopped for almorexant and for Glaxo's DORA SB-649868, no less than 4 orexin receptor antagonists have reached phase II for insomnia, including Filorexant (MK-6096) and Suvorexant (MK-4305) from Merck. Suvorexant has since progressed to Phase III and dossier submission to the FDA. These four compounds are reported as DORAs, however, they equilibrate very slowly at one and/or the other orexin receptor, and thus at equilibrium may show more or less selectivity for OX1R or OX2R. The appropriate balance of antagonism of the two receptors for sleep is a point of

A Rule-Based Energy Management Strategy for a Plug-in Hybrid School Bus Based on a Controller Area Network Bus

Full Text Available This paper presents a rule-based energy management strategy for a plug-in hybrid school bus (PHSB. In order to verify the effectiveness and rationality of the proposed energy management strategy, the powertrain and control models were built with MATLAB/Simulink. The PHSB powertrain model includes an engine model, ISG (integrated started and generator model, drive motor model, power battery packs model, driver model, and vehicle longitudinal dynamics model. To evaluate the controller area network (CAN bus performance features such as the bus load, signal hysteresis, and to verify the reliability and real-time performance of the CAN bus multi-node control method, a co-simulation platform was built with CANoe and MATLAB/Simulink. The co-simulation results show that the control strategy can meet the requirements of the PHSB’s dynamic performance. Meanwhile, the charge-depleting mode (CD and charge-sustaining mode (CS can switch between each other and maintain a state-of-charge (SoC of around 30%, indicating that the energy management strategy effectively extends the working period of the CD mode and improves the fuel economy further. The energy consumption per 100 km includes 13.7 L diesel and 10.5 kW·h electricity with an initial SoC of 75%. The CANoe simulation results show that the bus communication performs well without error frames.

The preharvest application of Ca-containing foliar fertilizers can reduce bitter pit (BP) incidence in apples and improve fruit quality by increasing the Ca content and decreasing both the N content and the N/Ca ratio in fruits. In this study, we aimed to investigate the control efficacy of Ca-containing fertilizers on BP incidence and the effects on the Ca and N contents in bagged 'Fuji' apple by spraying the foliar fertilizer containing calcium chloride (CaCl 2 ), calcium nitrate [Ca(NO 3 ) 2 ] or calcium formate [Ca(HCOO) 2 ] at early stage [5 days after full bloom (DAFB) + 40 DAFB] and at late stage (80 DAFB + 125 DAFB). The BP incidences were reduced significantly with the reduce percentage of 43.2~73.0%, and the efficacy of spraying at early stage was significantly higher than that of spraying at late stage. The Ca content of bagged apple fruits was increased while the N content and N/Ca ratio were decreased after spraying Ca-containing foliar fertilizers, however, the Ca content, N content and N/Ca ratio of apple leaves were differentially influenced. The foliar fertilizer containing CaCl 2, Ca(NO 3 ) 2 or Ca(HCOO) 2 could be used at early stage to control BP in apple and improve the quality of bagged apple fruits.

2009-01-01

Synthetic hydroxyapatites incorporating small amounts of Si have shown improved biological performances in terms of enhanced bone apposition, bone in-growth and cell-mediated degradation. This paper reports a systematic investigation on Si-substituted hydroxyapatite (Si 1.40 wt%) nanopowders produced following two different conventional wet methodologies: (a) precipitation of Ca(NO 3 ) 2 .4H 2 O and (b) titration of Ca(OH) 2 . The influence of the synthesis process on composition, thermal behaviour and sinterability of the resulting nanopowders is studied. Samples were characterised by electron microscopy, induced coupled plasma atomic emission spectroscopy, thermal analysis, infrared spectroscopy, N 2 adsorption measurements, X-ray diffraction and dilatometry. Semicrystalline Si-substituted hydroxyapatite powders made up of needle-like nanoparticles were obtained, the specific surface area ranged between 84 and 110 m 2 /g. Pure and Si-substituted hydroxyapatite nanopowders derived from Ca(NO 3 ) 2 .4H 2 O decomposed around 1000 deg. C. Si-substituted hydroxyapatite nanopowders obtained from Ca(OH) 2 were thermally stable up to 1200 deg. C and showed a distinct decreased thermal stability with respect to the homologous pure sample. Si-substituted hydroxyapatites exhibited higher sintering temperature and increased total shrinkage with respect to pure powders. Nanostructured dense ceramics were obtained by sintering at 1100 deg.

Full Text Available National Museums Scotland (NMS has in its collections a Mäori war canoe (A.UC.767 or 'Waka Taua 'from New Zealand'.' The 'Waka' had been held in the Museum stores for many years and due to its incompleteness and poor state of repair had not been on public display. It was proposed that the 'Waka' be restored with the intention of it being a focal point of a new permanent gallery in the Royal Museum in Edinburgh dedicated to South Pacific cultures and communities. The gallery was being developed as one part of a £44 million redevelopment of Royal Museum building. Due to its poor condition assistance was sought to help in the restoration, reconstruction and visual interpretation of the 'Waka'. NMS commissioned George Nuku, a Mäori carver, to remake  missing parts. Nuku uses a variety of mediums to carve including Polymethyl Methacrylate (PMMA. This made a clear distinction between new and original material that could be easily read by the public and reflected Nuku’s conceptual vision of creating physical “ghosts” influenced by the original carvings. Due to the composite construction and condition of the canoe the  project became more complex and  involved. This paper describes how the renewal was done and relationships that developed between the artist, curator and conservator.

Orexin receptor antagonists have demonstrated clinical utility for the treatment of insomnia. The majority of clinical efforts to date have focused on the development of dual orexin receptor antagonists (DORAs), small molecules that antagonize both the orexin 1 and orexin 2 receptors. Our group has recently disclosed medicinal chemistry efforts to identify highly potent, orally bioavailable selective orexin 2 receptor antagonists (2-SORAs) that possess acceptable profiles for clinical development. Herein we report additional SAR studies within the 'triaryl' amide 2-SORA series focused on improvements in compound stability in acidic media and time-dependent inhibition of CYP3A4. These studies resulted in the discovery of 2,5-disubstituted isonicotinamide 2-SORAs such as compound 24 that demonstrated improved stability and TDI profiles as well as excellent sleep efficacy across species.

J. Gajewski

2011-11-01

Full Text Available The goal of the study was to determine a strength profile in young female athletes practising different sports and to use allometry to evaluate muscular strength with respect to body mass. The study included 42 women who practised taekwondo (n = 10, weightlifting (n = 10, canoeing (n = 14 and speed skating (n = 8. Measurements of maximal muscle torques under static conditions in 10 groups of flexors and extensors of the elbow, shoulder, hip, knee and trunk were carried out. The MANCOVA procedure was employed to compare means between the groups. A logarithm of body mass was adopted as a covariate. Relationships between body mass and muscle torques in each muscle group were determined using a procedure of linear regression. The analysis of residuals was employed for the evaluation of maximal muscle torques. Mean values of logarithms of maximal muscle torques were significantly different for the representatives of individual sports and they depended on the logarithm of body mass. It was proposed to use a mean of residuals normalized for individual muscle groups as a synthetic strength index (mean of the strength profile. The women practising canoeing were characterized by the highest strength index. Its lowest values were obtained by weightlifting and taekwondo athletes. Differences in strength profiles in the tested athletes were attributed to the specific nature of their sports. It is suggested to use an allometric relationship scaled by body mass for strength assessment.

Climate windows for Polynesian voyaging to New Zealand and Easter Island.

Goodwin, Ian D; Browning, Stuart A; Anderson, Atholl J

2014-10-14

Debate about initial human migration across the immense area of East Polynesia has focused upon seafaring technology, both of navigation and canoe capabilities, while temporal variation in sailing conditions, notably through climate change, has received less attention. One model of Polynesian voyaging observes that as tradewind easterlies are currently dominant in the central Pacific, prehistoric colonization canoes voyaging eastward to and through central East Polynesia (CEP: Society, Tuamotu, Marquesas, Gambier, Southern Cook, and Austral Islands) and to Easter Island probably had a windward capacity. Similar arguments have been applied to voyaging from CEP to New Zealand against prevailing westerlies. An alternative view is that migration required reliable off-wind sailing routes. We investigate the marine climate and potential voyaging routes during the Medieval Climate Anomaly (MCA), A.D. 800-1300, when the initial colonization of CEP and New Zealand occurred. Paleoclimate data assimilation is used to reconstruct Pacific sea level pressure and wind field patterns at bidecadal resolution during the MCA. We argue here that changing wind field patterns associated with the MCA provided conditions in which voyaging to and from the most isolated East Polynesian islands, New Zealand, and Easter Island was readily possible by off-wind sailing. The intensification and poleward expansion of the Pacific subtropical anticyclone culminating in A.D. 1140-1260 opened an anomalous climate window for off-wind sailing routes to New Zealand from the Southern Austral Islands, the Southern Cook Islands, and Tonga/Fiji Islands.

Full Text Available “Subversive discourses in silent films” aims to analyse the gender transgression that emerges in certain movies of the silent period. These being silent films, their meaning can only be understood from the content of the images. Directors of the silent period were aware of the importance of images and of their power to put across their views to spectators. The field of filmmaking was new but it was not ungendered, and women filmmakers knew that their films were the vehicle to make spectators aware of their feminist positions. Le matelas alcoolique, La souriante Mme. Beudet and Dora Films of America Shorts are examples of this privilege since, although they belong to two periods of silent film history and have different aims, the directors and the films selected are good examples to be revisited with a gender perspective.

“Discursos subversivos en el cine no hablado” se propone analizar las transgresiones de género que aparecen en algunas películas del cine mudo. Por sus características al tratarse de un cine no hablado, lo que sugieren algunas imágenes es fundamental para entender los significados de las películas. Las directoras de aquella época eran conocedoras de la importancia de las imágenes y del poder que les confería la cámara para expresar sus reivindicaciones al público espectador. El campo de la cinematografía era nuevo, pero tenía género y las directoras sabían que sus películas eran el vehículo para dar a conocer su articulación como feministas. Le matelas alcoolique, La souriante Mme.

This study addresses two challenges which the minerals industry faces in the rehabilitation of minespoils. The first is to re-establish a soil ecosystem that will sustainably support native vegetation. The second is to overcome seed dormancy mechanisms that often lead to the failure of native plant establishment on sites affected by mining. This paper outlines the results of the ongoing study on the rehabilitation of a coal stockpile at Cooranbong Colliery, Dora Creek, New South Wales. The trial was established to determine the benefits of utilising dewatered biosolids as a soil conditioner for the growth of native trees by direct seeding techniques, and also to investigate the effectiveness of seed treatments on seed germination rates. Two seed treatment techniques, new to attempts to re-establish native species on minespoils, were trialed using, in turn, hot water and smoke. 8 refs., 1 fig., 2 tabs.

Full Text Available In the growth process children are influenced not only by models embodied by reference adults and transmitted by formal education agencies, but also – and, one might say, especially – by those models that the media propose. In particular, children read themselves, amplify their experiences, and open themselves to the possible, through the stories that the media offer.While, nowadays, tv series as Peppa Pig, Teletubbies, Dora the Explorer or Bo on the Go! merely confirm adult expectations, confining children within models that act as ‘cages’ from which it is difficult to escape, Masha and the Bear breaks the rules and undermines traditional education systems. Like the outdoor education theories, and like the educational experiments related to them, Masha and the Bear also actively participates in the endeavour of educational renewal now in progress.

Clinical and research settings often require sequencing multiple respiratory tests in a brief visit. Guidelines recommend measuring the concentration of exhaled nitric oxide (FeNO) before spirometry, but evidence for a spirometry carryover effect on FeNO is mixed. Only one study has investigated spirometry carryover effects on multiple flow FeNO analysis. The objective of this study was to evaluate evidence for carryover effects of recent spirometry on three exhaled NO summary measures: FeNO at 50 ml/s, airway wall NO flux [J'awNO] and alveolar NO concentration [CANO] in a population-based sample of schoolchildren. Participants were 1146 children (191 with asthma), ages 12-15, from the Southern California Children's Health Study who performed spirometry and multiple flow FeNO on the same day. Approximately, half the children performed spirometry first. Multiple linear regression was used to estimate differences in exhaled NO summary measures associated with recent spirometry testing, adjusting for potential confounders. In the population-based sample, we found no evidence of spirometry carryover effects. However, for children with asthma, there was a suggestion that exhaled NO summary measures assessed ≤6 min after spirometry were lower (FeNO: 25.8% lower, 95% CI: -6.2%, 48.2%; J'awNO: 15.1% lower 95% CI: -26.5%, 43.0%; and CANO 0.43 parts per billion lower, 95% CI: -0.12, 0.98). In clinical settings, it is prudent to assess multiple flow FeNO before spirometry. In studies of healthy subjects, it may not be necessary to assess FeNO first.

Electrospinning of calcium carbonate fibers and their conversion to nanocrystalline hydroxyapatite

International Nuclear Information System (INIS)

Holopainen, Jani; Santala, Eero; Heikkilä, Mikko; Ritala, Mikko

2014-01-01

Calcium carbonate (CaCO 3 ) fibers were prepared by electrospinning followed by annealing. Solutions consisting of calcium nitrate tetrahydrate (Ca(NO 3 ) 2 ·4H 2 O) and polyvinylpyrrolidone (PVP) dissolved in ethanol or 2-methoxyethanol were used for the fiber preparation. By varying the precursor concentrations in the electrospinning solutions CaCO 3 fibers with average diameters from 140 to 290 nm were obtained. After calcination the fibers were identified as calcite by X-ray diffraction (XRD). The calcination process was studied in detail with high temperature X-ray diffraction (HTXRD) and thermogravimetric analysis (TGA). The initially weak fiber-to-substrate adhesion was improved by adding a strengthening CaCO 3 layer by spin or dip coating Ca(NO 3 ) 2 /PVP precursor solution on the CaCO 3 fibers followed by annealing of the gel formed inside the fiber layer. The CaCO 3 fibers were converted to nanocrystalline hydroxyapatite (HA) fibers by treatment in a dilute phosphate solution. The resulting hydroxyapatite had a plate-like crystal structure with resemblance to bone mineral. The calcium carbonate and hydroxyapatite fibers are interesting materials for bone scaffolds and bioactive coatings. - Highlights: • Calcium carbonate fibers were prepared by electrospinning. • The electrospun fibers crystallized to calcite upon calcination at 500 °C. • Spin and dip coating methods were used to improve the adhesion of the CaCO 3 fibers. • The CaCO 3 fibers were converted to hydroxyapatite by treatment in phosphate solution. • The hydroxyapatite fibers consisted of plate-like nanocrystals

Full Text Available Abstract Background Degummed silk fibroin from Bombyx mori (silkworm has potential carrier capabilities for drug delivery in humans; however, the processing methods have yet to be comparatively analyzed to determine the differential effects on the silk protein properties, including crystalline structure and activity. Methods In this study, we treated degummed silk with four kinds of calcium-alcohol solutions, and performed secondary structure measurements and enzyme activity test to distinguish the differences between the regenerated fibroins and degummed silk fibroin. Results Gel electrophoresis analysis revealed that Ca(NO32-methanol, Ca(NO32-ethanol, or CaCl2-methanol treatments produced more lower molecular weights of silk fibroin than CaCl2-ethanol. X-ray diffraction and Fourier-transform infrared spectroscopy showed that CaCl2-ethanol produced a crystalline structure with more silk I (α-form, type II β-turn, while the other treatments produced more silk II (β-form, anti-parallel β-pleated sheet. Solid-State 13C cross polarization and magic angle spinning-nuclear magnetic resonance measurements suggested that regenerated fibroins from CaCl2-ethanol were nearly identical to degummed silk fibroin, while the other treatments produced fibroins with significantly different chemical shifts. Finally, enzyme activity test indicated that silk fibroins from CaCl2-ethanol had higher activity when linked to a known chemotherapeutic drug, L-asparaginase, than the fibroins from other treatments. Conclusions Collectively, these results suggest that the CaCl2-ethanol processing method produces silk fibroin with biomaterial properties that are appropriate for drug delivery.

Johnson, Lane B; Kipfmueller, Kurt F

2016-06-01

We reconstructed fire occurrence near a fur-trade era canoe travel corridor (used ca. 1780-1802) in the Quetico-Superior region west of Lake Superior to explore the possibility of human influence on pre-fire suppression rates of fire occurrence. Our research objectives were to (1) examine the spatial and temporal patterns of fire in the study area, (2) test fires' strength of association with regional drought, and (3) assess whether reconstructed fire frequencies could be explained by observed rates of lightning fire ignition over the modern period of record. We developed a 420-year fire history for the eastern portion of Lac La Croix in the Boundary Waters Canoe Area Wilderness (BWCAW). Seventy-one fire-scarred samples were collected from remnant Pinus resinosa Ait. (red pine) stumps and logs from thirteen distinct island and three mainland forest stands. Collectively these samples contained records of 255 individual fire scars representing 79 fire events from 1636 to 1933 (study area mean fire intervals [MFI] 3.8 yr). Reconstructed fires were spatially and temporally asynchronous and not strongly associated with regional drought (P > 0.05). When compared to the conservative, tree-ring reconstructed estimate of historical fire occurrence and modern lightning-caused fires (1929-2012), a noticeable change in the distribution and frequency of fires within the study area was evident with only two lightning-ignited island fires since 1934 in the study area. Our results suggest a high likelihood that indigenous land use contributed to surface fire ignitions within our study area and highlights the importance of examining the potential effects of past indigenous land use when determining modern approaches to fire and wilderness management in fire-adapted ecosystems.

Early ceramic sites in southern Lau, Fiji

Clark, G.

2009-01-01

The Lau Group is a dispersed chain of islands in east Fiji trending north-south on the inactive Lau Ridge remnant volcanic arc, which is part of the convergent margin system comprising the Lau Basin and Tonga Ridge to the east. In the south of the Lau Group are several remote islands that are closer to Tangatapu than they are to the largest islands of Viti Levu and Vanua Levu in the Fiji Group. Two of these islands, Vatoa and Doi islands in the Ono-i-Lau Group, were visited briefly in 2006 after field work on Kabara when the government supply boat 'Sandy' made scheduled stops to unload and collect cargo. Lapita pottery and a fortification were recorded on Doi Island in the Ono Group, and on Vatoa Island a site with plain ware ceramics dating to c. 2000 cal. BP was located. The position of the two remote islands lying between the main islands of Fiji and Tongan archipelago suggests they were particularly subject to influence from population contacts and movements from islands to their east and west in prehistory. In the eighteenth and nineteenth century central and southern Lau were the centre of an important canoe building industry based on the hardwood Instia bijuga (vesi) used to construct large sailing canoes which were the prerogative of Tongan and Fijian chiefs. Archaeological and linguistic studies of the Lau Group suggest a complicated history of population movements earlier during Lapita (2900-2500 BP) and post-Lapita (∼2500-1000 BP) times, which can be examined from the study of ceramic sites in southern Lau.

Application of immobilizing agents may efficiently reduce the bioavailability of nickel (Ni) in the soil. Here we report the effect of biochar (BC), gravel sludge (GS) and zeolite (ZE) as a sole treatment and their combinations on the bioavailability of Ni after their application into a Ni-polluted soil. The bioavailability of Ni after the application of immobilizing agents was assessed through an indicator plant (red clover) and chemical indicators of bioavailability like soil water extract (SWE), DTPA and Ca(NO 3 ) 2 extracts. Additionally, the effects of Ni bioavailability and immobilizing agents on the growth, physiological and biochemical attributes of red clover were also observed. Application of ZE significantly reduced Ni concentrations in all chemical extracts compared to rest of the treatments. Similarly, the combined application of BC and ZE (BC+ ZE) significantly reduced Ni concentrations, reactive oxygen species (ROS) whereas, significant enhancement in the growth, physiological and biochemical attributes along with an improvement in antioxidant defence machinery of red clover plant, compared to rest of the treatments, were observed. Furthermore, BC+ ZE treatment significantly reduced bioconcentration factor (BCF) and bioaccumulation factor (BAF) of Ni in red clover, compared to rest of the treatments. The Ni concentrations in red clover leaves individually reflected a good correlation with Ni concentrations in the extracts (SWE at R 2 =0.79, DTPA extract at R 2 =0.84 and Ca(NO 3 ) 2 extracts at R 2 =0.86). Our results indicate that combined application of ZE and BC can significantly reduce the Ni bioavailability in the soil while in parallel improve the antioxidant defence mechanism in plants.

2002-12-01

Fishery resources are a vital source of food and make valuable economic contributions to the local communities involved in fishery activities along the 850 km stretch of the Tanzania coastline and numerous islands. Small-scale artisanal fishery accounts for the majority of fish catch produced by more than 43 000 fishermen in the country, mainly operating in shallow waters within the continental shelf, using traditional fishing vessels including small boats, dhows, canoes, outrigger canoes and dinghys. Various fishing techniques are applied using uncomplicated passive fishing gears such as basket traps, fence traps, nets as well as different hook and line techniques. Species composition and size of the fish varies with gear type and location. More than 500 species of fish are utilized for food with reef fishes being the most important category including emperors, snappers, sweetlips, parrotfish, surgeonfish, rabbitfish, groupers and goatfish. Most of the fish products are used for subsistence purposes. However, some are exported. Destructive fishing methods such as drag nets and dynamite fishing pose a serious problem as they destroy important habitats for fish and other organisms, and there is a long-term trend of overharvested fishery resources. However, fishing pressure varies within the country as fishery resources are utilized in a sustainable manner in some areas. For this report more than 340 references about Tanzanian fishery and fish ecology were covered. There are many gaps in terms of information needed for successful fishery management regarding both basic and applied research. Most research results have been presented as grey literature (57%) with limited distribution; only one-fifth were scientific publications in international journals.

Full Text Available Riegl’s lecture about Maori ornament was held before the Anthropological Society in Vienna in 1890 and anticipates much of what he then said in his Stilfragen. After reiterating his milestone criticism of the ‘materialist’ theories of Semper and his followers, he suggests that the spiral motif was used for more profound and spontaneous reasons at the knee of a figure and the point of a canoe because of its complexity in being read in more than one direction, with and without other intervening elements.

Nutrition for power sports: middle-distance running, track cycling, rowing, canoeing/kayaking, and swimming.

Science.gov (United States)

Stellingwerff, Trent; Maughan, Ronald J; Burke, Louise M

2011-01-01

Contemporary training for power sports involves diverse routines that place a wide array of physiological demands on the athlete. This requires a multi-faceted nutritional strategy to support both general training needs--tailored to specific training phases--as well as the acute demands of competition. Elite power sport athletes have high training intensities and volumes for most of the training season, so energy intake must be sufficient to support recovery and adaptation. Low pre-exercise muscle glycogen reduces high-intensity performance, so daily carbohydrate intake must be emphasized throughout training and competition phases. There is strong evidence to suggest that the timing, type, and amount of protein intake influence post-exercise recovery and adaptation. Most power sports feature demanding competition schedules, which require aggressive nutritional recovery strategies to optimize muscle glycogen resynthesis. Various power sports have different optimum body compositions and body weight requirements, but increasing the power-to-weight ratio during the championship season can lead to significant performance benefits for most athletes. Both intra- and extracellular buffering agents may enhance performance, but more research is needed to examine the potential long-term impact of buffering agents on training adaptation. Interactions between training, desired physiological adaptations, competition, and nutrition require an individual approach and should be continuously adjusted and adapted.

Surviving Secularization: Masking the Spirit in the Jankunu (John Canoe Festivals of the Caribbean

Directory of Open Access Journals (Sweden)

Kenneth M. Bilby

2010-12-01

Full Text Available Jankunu (Jonkonnu, Junkanoo, an Afro-Caribbean Yuletide tradition centering on masked dance, is generally characterized as a secular festival. This article presents contemporary ethnographic evidence showing that certain older variants of the tradition remain closely connected with African-derived religious concepts and practices. On the basis of this new evidence, the author argues for a reexamination and reevaluation of the historical significance of this tradition, which even today, despite its ostensible secularity, has vaguely "spiritual" associations for many in the region—including some of those who represent it as "secular." The article interprets this apparent contradiction as the result of a historical process of secularization (in response to the stigmatization of African modes of religiosity that was only partly successful.

Palaeotsunamis and their significance for prehistoric coastal communities

Science.gov (United States)

Goff, J. R.

2011-12-01

The damage caused by large tsunamis to human populations at the coast has been all too evident over the past few years. However, while we have seen the immediate after-effects of such events, we are less familiar with the longer term changes associated with them. Using prehistoric New Zealand as a case study, the talk first addresses the wider geological context associated with a tsunami - what caused it and what were the consequences for the physical environment? Prehistoric Maori lived predominantly in coastal settlements, particularly during their early settlement period. They had far ranging canoe trade routes and made widespread use of intertidal and coastal resources. As such it is possible to determine much of the ecological and societal ramifications of a 15th century tsunami inundation. The 15th century tsunami is recorded in numerous purakau or oral recordings. These form part of Maori Traditional Environmental Knowledge (TEK), but the event can also be identified through archaeological, geological and palaeo-ecological indicators. One of several purakau from the 15th century refers to the "Coming of the Sand". This centres on a place called Potiki-taua, where Potiki and his group settled. Mango-huruhuru, the old priest, built a large house on low land near the sea while Potiki-roa and his wife put theirs on higher ground further inland. Mango-huruhuru's house had a rocky beach in front of it that was unsuitable for landing canoes and so he decided to use his powers to bring sand from Hawaiki. After sunset he sat on his roof and recited a karakia (prayer/chant). On conclusion a dark cloud with its burden of sand reached the shore. The women called out "A! The sea rises; the waves and the sand will overwhelm us". The people fell where they stood and were buried in the sand along with the house and cultivations and all the surrounding country, and with them, the old priest and his youngest daughter (memorialised and turned into a rock which stands there

The effect of exogenous calcium nitrate [Ca(NO3)2] (6 mM) on the dissipation of excess excitation energy in the photosystem II (PSII) antenna, especially on the level of D1 protein and the xanthophyll cycle in peanut plants under heat (40°C) and high irradiance (HI) (1 200 µmol m−2 s−1) stress were investigated. Compared with the control plants [cultivated in 0 mM Ca(NO3)2 medium], the maximal photochemical efficiency of PSII (Fv/Fm) in Ca2+-treated plants showed a slighter decrease after 5 h of stress, accompanied by higher non-photochemical quenching (NPQ), higher expression of antioxidative genes and less reactive oxygen species (ROS) accumulation. Meanwhile, higher content of D1 protein and higher ratio of (A+Z)/(V+A+Z) were also detected in Ca2+-treated plants under such stress. These results showed that Ca2+ could help protect the peanut photosynthetic system from severe photoinhibition under heat and HI stress by accelerating the repair of D1 protein and improving the de-epoxidation ratio of the xanthophyll cycle. Furthermore, EGTA (a chelant of Ca ion), LaCl3 (a blocker of Ca2+ channel in cytoplasmic membrane), and CPZ [a calmodulin (CaM) antagonist] were used to analyze the effects of Ca2+/CaM on the variation of (A+Z)/(V+A+Z) (%) and the expression of violaxanthin de-epoxidase (VDE). The results indicated that CaM, an important component of the Ca2+ signal transduction pathway, mediated the expression of the VDE gene in the presence of Ca to improve the xanthophyll cycle.

Certain plant species have been shown to vigorously accumulate some metals from soil, and thus represent promising and effective remediation alternatives. In order to select the optimum forms of nitrogen (N) fertilizers for the arsenic (As) hyperaccumulator, Pteris vittata L., to maximize As extraction, five forms of N were added individually to different treatments to study the effect of N forms on As uptake of the plants under soil culture in a greenhouse. Although shoot As concentration tended to decrease and As translocation from root to shoot was inhibited, overall As accumulation was greater due to higher biomass when N fertilizer was added. Arsenic accumulation in plants with N fertilization was 100-300% more than in the plants without N fertilization. There were obvious differences in plant biomass and As accumulation among the N forms, i.e., NH4HCO3, (NH4)2S04, Ca(NO3)2, KNO3, urea. The total As accumulation in the plants grown in As-supplied soil, under different forms of N fertilizer, decreased as NH4HCO3>(NH4)2S04 > urea > Ca(NO3)2 >KNO3>CK. The plants treated with N and As accumulated up to 5.3-7.97 mg As/pot and removed 3.7-5.5% As from the soils, compared to approximately 2.3% of As removal in the control. NH4+ -N was apparently more effective than other N fertilizers in stimulating As removal when soil was supplied with As at initiation. No significant differences in available As were found among different forms of N fertilizer after phytoremediation. It is concluded that NH4+ -N was the preferable fertilizer for P. vittata to maximize As removal.

Detailed mechanistic investigation into the S-nitrosation of cysteamine.

The nitrosation of cysteamine (H 2 NCH 2 CH 2 SH) to produce cysteamine- S -nitrosothiol (CANO) was studied in slightly acidic medium by using nitrous acid prepared in situ. The stoichiometry of the reaction was H 2 NCH 2 CH 2 SH + HNO 2 → H 2 NCH 2 CH 2 SNO + H 2 O. On prolonged standing, the nitrosothiol decomposed quantitatively to yield the disulfide, cystamine: 2H 2 NCH 2 CH 2 SNO → H 2 NCH 2 CH 2 S-SCH 2 CH 2 NH 2 + 2NO. NO 2 and N 2 O 3 are not the primary nitrosating agents, since their precursor (NO) was not detected during the nitrosation process. The reaction is first order in nitrous acid, thus implicating it as the major nitrosating agent in mildly acidic pH conditions. Acid catalyzes nitrosation after nitrous acid has saturated, implicating the protonated nitrous acid species, the nitrosonium cation (NO + ) as a contributing nitrosating species in highly acidic environments. The acid catalysis at constant nitrous acid concentrations suggests that the nitrosonium cation nitrosates at a much higher rate than nitrous acid. Bimolecular rate constants for the nitrosation of cysteamine by nitrous acid and by the nitrosonium cation were deduced to be 17.9 ± 1.5 (mol/L) -1 s -1 and 6.7 × 10 4 (mol/L) -1 s -1 , respectively. Both Cu(I) and Cu(II) ions were effective catalysts for the formation and decomposition of the cysteamine nitrosothiol. Cu(II) ions could catalyze the nitrosation of cysteamine in neutral conditions, whereas Cu(I) could only catalyze in acidic conditions. Transnitrosation kinetics of CANO with glutathione showed the formation of cystamine and the mixed disulfide with no formation of oxidized glutathione (GSSG). The nitrosation reaction was satisfactorily simulated by a simple reaction scheme involving eight reactions.

Do fish have rights in artisanal fisheries?

Full Text Available Artisanal fishers in developing world are unaware that fish are capable of suffering or discomfort, though researches have shown that fish do feel pain. Five fish welfare domains have been identified which constitute their rights in their environment. The needs of wild fish are usually provided in their natural, undisturbed and unperturbed aquatic environment, of which the fish will prefer. However, various anthropogenic activities by humans (including artisanal fisheries itself and some natural perturbations in the watershed, riparian zone, water body of the fish habitat and on the fish tend to take away these needs thereby compromising the fish welfare. These activities include environmental degradation, boat/canoe building, use of motorized engine boats/canoes, use of active and passive fishing gears, obnoxious cultural, religious and social fishing practices, fish harvesting, handling and processing among others. One way to understand the welfare needs of an individual fish is to understand its biology. Poor welfare conditions could then be assessed by how far the individual fish has deviated from the normal conditions. Non-intrusive signs based on the health, behavior, morphological anomalies, swimming, reduction in population and growth, outbreak of parasitic infections, injuries and loss of condition can be used to assess fish whose welfare has been compromised. Artisanal fishers should not only be concerned with catch, but, also the welfare of the fish being caught. This is because if the welfare of the fish is compromised, it is going to definitely affect the catch. As indispensable as fish is to humans, humans should not derive its pleasure at the expense of fish suffering. Human activities that impinge on the welfare of wild fish may not necessarily be stopped, but at least minimized in order to have continued sustainable artisanal exploitation of the fisheries.

In this paper, the synthesis of hydroxyapatite (HAp) nanopowder was studied by chemical precipitation method at different values of reaction temperature, settling time, Ca/P ratio, calcination temperature, (NH4)2HPO4 addition rate, initial concentration of Ca(NO3)2 and (NH4)2HPO4. Analysis results of properties, morphology, structure of HAp powder from infrared (IR) spectra, x-ray diffraction (XRD), energy dispersive x-ray (EDX) spectra and scanning electron microscopy (SEM) indicated that the synthesized HAp powder had cylinder crystal shape with size less than 100 nm, single-phase structure. The variation of the synthesis conditions did not affect the morphology but affected the size of HAp crystals.

[Sigmund Freud and the "Zeitschrift für Hypnotismus"].

Tanner, Terence A

2005-01-01

While Freud was always ready to acknowledge the debt that psychoanalysis owed to hypnotism, his engagement in its study and medical application is often seen by historians as little more than a passing phase on the way to psychoanalysis proper. This paper attempts to redress the balance by exploring Freud's association with the most influential German-language journal devoted to hypnotism, the Zeitschrift für Hypnotismus. Freud not only contributed a paper to this periodical but also served on its editorial board for the first three years of its existence. There also appeared in the journal one review and six abstracts of his work. After a condensed bibliographical account of the journal, a summary is given of Freud's intellectual and professional contacts and exchanges with three of the key individuals associated with it: August Forel, Jonas Grossmann and Oskar Vogt. Finally clarification is given of the publication history of the "Dora" case history and the chronology of its rejection for publication by Korbinian Brodmann, editor of the journal when it became the Journal für Psychologie und Neurologie.

Testing sex and gender in sports; reinventing, reimagining and reconstructing histories.

Science.gov (United States)

Heggie, Vanessa

2010-12-01

Most international sports organisations work on the premise that human beings come in one of two genders: male or female. Consequently, all athletes, including intersex and transgender individuals, must be assigned to compete in one or other category. Since the 1930s (not, as is popularly suggested, the 1960s) these organisations have relied on scientific and medical professionals to provide an 'objective' judgement of an athlete's eligibility to compete in women's national and international sporting events. The changing nature of these judgements reflects a great deal about our cultural, social and national prejudices, while the matter of testing itself has become a site of conflict for feminists and human rights activists. Because of the sensitive nature of this subject, histories of sex testing are difficult to write and research; this has lead to the repetition of inaccurate information and false assertions about gender fraud, particularly in relation to the 'classic' cases of Stella Walsh and Heinrich/Hermann/Dora Ratjen. As historians, we need to be extremely careful to differentiate between mythologies and histories. Copyright © 2010 Elsevier Ltd. All rights reserved.

Our research, focussed on art therapy with primary school children, guided us to the footsteps of women pioneers in the research about children's psyche, like Anna Freud, Melanie Klein, Margaret Loewenfeld, Dora Kalff. We have been inspired by their very personal but nevertheless somehow similar type of research, to work with the children in a blue sand pit, where they could construct and play their personal fairy tales. Thus they share with us their momentary preoccupations, without being forced to talk about them. They are revealing their internal structures, and are integrating, by narration and projection on those figurines in action, their deficient defense mechanisms as well as their negative tendencies. Based on this approach, we expect that there will by an amelioration of their social skills, an enhancement of their intrinsic motivation, and a diminution of their conduct disorders. The analyze will be done by questionnaires and rating scales constructed especially for this research, as well as by sociograms, with the help of descriptive non parametric statistics.

Patagonia, Land of Nomads: A Glance at a Territory Shaped by Displacement

Directory of Open Access Journals (Sweden)

Pablo Chiuminatto

2016-05-01

Full Text Available By the end of the nineteenth century, as global voyages became popular, and transcontinental empires settled, remote corners of the third world such as Patagonia began to be explored and became the subject of European travel literatures. The opening of this region to the global scenario produced profound transformations in its territorial conformation, poetic imaginary, and local culture. As Patagonia became a land of travellers, local nomads which had inhabited this land for centuries became extinguished. The historical context of this re-shaping is conceptualised in literary theory through notions such as nomadism, elaborated by Gilles Deleuze and its aesthetical counterpart, geo-poetics, by Kenneth White. The travel literature about Patagonia, such as that produced by Charles Darwin, Lady Florence Dixie, and Bruce Chatwin, depicts the difficulties these travellers faced in trying to endow their writings of adequate descriptions and images. Instead, they recurred to images from their homeland, and thus created an imaginary of Patagonia through displacement: their own, and that of images brought by themselves to this land. When Chilean poets like Gabriela Mistral and Pablo Neruda begun to write about Patagonia, they found it already populated by strange images, shaped indeed, by nomads, travellers and dis-located identities.

The two books made him a very famous historian. However, he would personally have preferred to be admired for his poetry or his plays, for he was a very gifted literary author. Nevertheless many of Strachey’s readers have appreciated his conception of biography, as a means of personal confession while studying the destiny of a public figure. Indeed the Stracheyan way of life, free from Victorian moral standards and guided by the rules of the Bloomsbury group, inspired his story of Victoria and Elizabeth. Both Queens at the end of their lives and at the height of their power carried on strange love affairs: Victoria with her Scottish gillie and Elizabeth with the Earl of Essex, thirty years her younger. In fact, both romances subtly reflect Strachey’s own love affairs. He was himself engaged in a kind of common life with Dora Carrington— the painter, thirteen years younger than him, with whom he was not sexually involved— while he engaged in numerous homosexual love affairs.

Basic research in the natural sciences rests on a long tradition of evaluation. However, since the San Francisco Declaration on Research Assessment (DORA) came out in 2012, there has been intense discussion in the natural sciences, above all amongst researchers and funding agencies in the different fields of applied research and scientific service. This discussion was intensified when climate services and other fields, used to make users participate in research and development activities (co-creation), demanded new evaluation methods appropriate to this new research mode. This paper starts by describing a comprehensive and interdisciplinary literature overview of indicators to evaluate co-creation of knowledge, including the different fields of integrated knowledge production. Then the authors harmonize the different elements of evaluation from literature in an evaluation cascade that scales down from very general evaluation dimensions to tangible assessment methods. They describe evaluation indicators already being documented and include a mixture of different assessment methods for two exemplary criteria. It is shown what can be deduced from already existing methodology for climate services and envisaged how climate services can further to develop their specific evaluation method.

Full Text Available I had several „direct” meetings with Ligeti, whom I have known and met at the Festival of Darmstadt, in the 1970s, and at a master class in Aix-en-Provence in 1978. The „indirect” meetings were numerous, whether I listened to and analysed most of his works, many of them in the course of composition at the „Gh. Dima” Academy of Music Cluj, or as an interpreter of his music, with works scheduled by „Ars Nova” Ensemble or the Chamber Orchestra of the Cluj Philharmonic, where I conducted the rehearsals of the work „Ramifications” for Zagreb Biennale in 1971. Some of these activities had as echo the two letters received from Ligeti. Another equally important echo was the letter of thanks that he sent to the composer Dora Cojocaru, whose doctoral thesis was devoted to his creation, made under my guidance, and which has had more than his laudatory assessments. After the master classes with Olivier Messaien and the meetings with Iannis Xenakis, my contact with Ligeti, the creator and the man, had a strong impact in my creative work.

Aerosol particles can serve as cloud condensation nuclei (CCN) to form cloud droplets, and its composition is a main factor governing whether an aerosol particle is an effective CCN. Pure mineral dust particles are poor CCN; however, changes in chemical composition of mineral dust aerosol particles, due to heterogeneous reactions with reactive trace gases in the troposphere, can modify their CCN properties. In this study we investigated the CCN activities of CaCO3 (as a surrogate for mineral dust) and its six atmospheric ageing products: Ca(NO3)2, CaCl2, CaSO4, Ca(CH3SO3)2, Ca(HCOO)2, and Ca(CH3COO)2. CaCO3 has a very low CCN activity with a hygroscopicity parameter (κ) of 0.001-0.003. The CCN activities of its potential atmospheric ageing products are significantly higher. For example, we determined that Ca(NO3)2, CaCl2 and Ca(HCOO)2 have κ values of ∼0.50, similar to that of (NH4)2SO4. Ca(CH3COO)2 has slightly lower CCN activity with a κ value of ∼0.40, and the κ value of CaSO4 is around 0.02. We further show that exposure of CaCO3 particles to N2O5 at 0% relative humidity (RH) significantly enhances their CCN activity, with κ values increasing to around 0.02-0.04. Within the experimental uncertainties, it appears that the variation in exposure to N2O5 from ∼550 to 15,000 ppbv s does not change the CCN activities of aged CaCO3 particles. This observation indicates that the CaCO3 surface may be already saturated at the shortest exposure. We also discussed the atmospheric implications of our study, and suggested that the rate of change in CCN activities of mineral dust particles in the troposphere is important to determine their roles in cloud formation.

Reconnaissance of the Manistee River, a cold-water river in the northwestern part of Michigan's Southern Peninsula

The cold-water streams of the northern states provide unique recreational values to the American people (wilderness or semi-wilderness atmosphere, fast-water canoeing, trout fishing), but expanding recreational needs must be balanced against the growing demand of water for public and industrial supplies, irrigation, and dilution of sewage and other wastes. In order to make intelligent decisions regarding use and management of water resources for recreation and other demands, an analysis of hydrologic factors related to recreation is essential.The Manistee River is one of Michigan's well-known trout streams-a stream having numerous public access sites and campgrounds. Upstream from Cameron Bridge (see location map) the Manistee is rated as a first-class trout stream but below Cameron Bridge the river is rated only as a fair trout stream by the Michigan Department of Natural Resources. As a Michigan canoe trail it is second only to the Au Sable River in popularity. Esthetically, the Manistee is one of Michigan's most attractive rivers, its waters flowing cool and clean, and around each bend a pleasant wilderness scene. This report deals with that part of the river upstream from State Highway M-66 at Smithville. Several hard-surface roads give access to the upper river as shown on the location map. Numerous dirt roads and trails give access to the river at intermediate points. The recreational values of the Manistee depend on its characteristics of streamflow, water quality, and bed and banks. This atlas describes these characteristics and shows how they relate to recreational use.Much of the information presented here was obtained from basic records of the U.S. Geological Survey's Water Resources Division. Additional information was obtained from field reconnaissance surveys in 1968 and 1969. The study was made in cooperation with the Michigan Geological Survey, Gerald E. Eddy, Chief. Assistance was also obtained from other sections of the Michigan Department of

Full Text Available A multidisciplinary project for the investigation of Mt. Vesuvius Structure was started in 1993. The core of the project is represented by a high resolution seismic tomography study by using controlled and natura1 sources. The main research objective is to investigate the feeding system of the vo1cano and to retrieve details of the upper crustal structure in the area. A first 2D using seismic experiment was performed in May 1994, with the aim of studing the feasibility of lIsing tomographic techniques for exploring the vo1cano interiors. Particularly, this experiment was designed to obtain information on the optimal sources-receivers configuration and on the depth extension of the volume sampled by shot-generated seismic waves. 66 three-component seismic stations and 16 single-component analogue instruments were installed by several Italian and French groups to record signals generated by three on-land, underground explosions. Sources and geophones were deployed along a 30-km NW-SE profile passing through the volcano crater. Receivers were placed at an average spacing of 250 m in the middle of the recording line and at 500 m outside. The arrival time data base was complemented by first P and S readings of micro earthquakes which occurred in the recent past within the volcano. The first arrival data set was preliminary used to determine the shallow structure of the volcano by applying Thurber's (1983 tomographic inversion technique. This analysis shows evidence for a high-velocity body which extends vertically from about 400 m below the crater down to at least 3000 m and for a shallow 300-500 m thick low-velocity cover which borders the edifice. Data from the distant shot show evidence for arrivals of deep reflected/converted phases and provide information on the deeper structure under the volcano. The results from the interpretation of 2D data are used for planning a 3D tomographic survey which will be cauied out in 1996.

Hydroxyapatite (HA), the main mineral component of bones and teeth, was synthesized by using the reaction between calcium nitrate tetrahydrate Ca(NO3)2∙4H2O and diammonium hydrogen phosphate (NH4)2HPO4 (DAHP) with a chemical precipitation method. The objective of this study is to utilize novel inorganic-organic nanocomposites for biomedical applications. HA is an inorganic component (75% w) and chitosan, alginate and albumin (Egg white) are organic components of nanocomposites (25% w). Nanocomposites were prepared in deionized water solutions, at room temperature, using a mechanical and magnetic stirrer for 48 h. The microstructure and morphology of sintered n-HAP were tested at different preheating temperature and laser sintering speed with scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR).

Calverley, R K

1980-01-01

René Goupil, the Patron Saint of Anaesthetists, and a Patron Saint of Canada, was born in Angers, France in 1608 and studied surgery. He joined the Jesuits as a donné or volunteer worker in 1640 and served in the then tiny colony of Quebec as one of the first medical workers of Canada. After earning meritorious praise for his skills, he again volunteered to attend the Hurons at Sainte Marie, a mission far beyond the frontiers. René's canoe party was ambushed. He was captured by the Mohawks and endured eight weeks of cruel torture before being killed on September 29, 1642. René was the first of eight North American martyrs whose dedication was recognized by canonization in 1930. St. René was appointed Patron Saint of Anaesthetists in 1951.

Full Text Available Present work is aimed at the fabrication of resorbable bioceramics based on calcium pyrophosphate (CPP from the synthesized powders of amorphous hydrated calcium pyrophosphate (AHCPP. Amorphous hydratedcalcium pyrophosphate in the form of nanopowders was precipitated from Ca(NO3 2 and (NH4 4P2O7 solutions at room temperature in the presence of PO3– ions. Crystalline CPP powder was fabricated from AHCPP by its thermal decomposition at 600 °C and consisted of β- and α- phase. Small particles, with the size less than 200 nm, were formed promoting sintering of the ceramic material. The final sample, sintered at 900 °C, exhibits microstructure with submicron grains, apparent density of 87% of theoretical density (TD and demonstrates tensile strength of 70 MPa.

Elastic-plastic fracture mechanics analysis of a pressure vessel with an axial outer surface flaw

1988-04-01

Elastic-plastic finite element analyses of a test vessel (steel 1.6310=20 MnMoNi 55) with a semi-elliptical axial outer surface crack have been performed. The variations of J and CTOD along the crack front and the stresse state in the vicinity of the crack are presented. The applicability of approaches to determine J is examined. The FE results are compared with the experimental data. The results are analyzed with respect to the validity of J-controlled crack growth. It will be shown that the local ductile crack growth and, especially, the 'canoe effect' for a semi-elliptical crack can only be described correctly if local J R -curves are used which account for the varying triaxiality of the stress state along the crack front.

Full Text Available Abstract Background Presently, different studies are conducted related to the topic of biomass potential to generate through anaerobic fermentation process alternative fuels supposed to support the existing fossil fuel resources, which are more and more needed, in quantity, but also in quality of so called green energy. The present study focuses on depicting an optional way of capitalizing agricultural biomass residues using anaerobic fermentation in order to obtain biogas with satisfactory characteristics.. The research is based on wheat bran and a mix of damaged ground grains substrates for biogas production. Results The information and conclusions delivered offer results covering the general characteristics of biomass used , the process parameters with direct impact over the biogas production (temperature regime, pH values and the daily biogas production for each batch relative to the used material. Conclusions All conclusions are based on processing of monitoring process results , with accent on temperature and pH influence on the daily biogas production for the two batches. The main conclusion underlines the fact that the mixture batch produces a larger quantity of biogas, using approximately the same process conditions and input, in comparison to alone analyzed probes, indicating thus a higher potential for the biogas production than the wheat bran substrate.

Representations of Eros: From Modernismo to Posmodernismo

Directory of Open Access Journals (Sweden)

Alicia Rita Rueda-Acedo

2014-12-01

Full Text Available In this paper I explore eroticism as a key element in the evolution from modernismo to posmodernismo. If eroticism is a crucial component to understand the binary concept of the world and the universe present in modernist poetry, postmodernist poets distance themselves from this outlook towards a “critic system”. In order to explore this shift, I analyze the works of postmodernist poets such as Baldomero Fernández Moreno, Ramón López Velarde and Regino E. Boti, and vanguardist poet Nicanor Parra, comparing their writing to Rubén Darío’s. I emphasize the evolution from Darío’s conception of the universe where women play an integral role to Parra’s conception of the woman as a viper and how this change is related to a substantial change of the conception of poetry. I also study eroticism in the work of Alfonsina Storni, Delmira Agustini and Gabriela Mistral as an instrument to critic and review the patriarchal cannon imposed by modernism. These poets eliminate the connection between eroticism and beauty, and they claim eroticism as a differentiating tool in their feminist writing and agenda. Sex and eroticism are elements that define and differentiate modernism from postmodernism, and can be considered as a crucial turning point for this shift.

The lower-temperature-pressure stability of pyrope in the presence of quartz in the system MgO-Al2O3-SiO2

Science.gov (United States)

Cheng, N.; Jenkins, D. M.

2017-12-01

Pyrope (Mg3Al2Si3O12) is the dominant component in garnets from type A eclogites. Determining the lower-pressure-temperature (P-T) stability of pyrope in the presence of quartz helps put constraints on the stability of quartz-bearing eclogites and therefore the depths to which crustal rocks in high pressure/ultra-high pressure (HP/UHP) terranes can be transferred. It also defines the lower-pressure stability of the nearly pure pyrope-bearing quartzites of the Dora Maira massif of the Western Alps (Chopin, 1984, Contrib. Min. Pet.). Aside from the approximate boundary proposed by Hensen & Essene (1971, Contrib. Min. Pet.), there has been no detailed study of the lower P-T stability of pyrope + quartz. A reversed determination of the reaction 3 enstatite + 2 kyanite = 2 pyrope + 2 quartz has been done in the system MgO-Al2O3-SiO2 over the P-T range of 900-1100 °C and 1.6-2.5 GPa for durations of 24 hours. Double capsules, one using pure enstatite and the other Al-rich (10 wt% Al2O3) enstatite in the starting mixtures, were used to obtain reversals on the Al content in the orthopyroxene (Opx). Experiments were done using a ½-inch diameter piston-cylinder press and NaCl-pyrex-MgO pressure media. Run products were analyzed using powder XRD and electron microprobe. Reaction direction was readily determined from peak height changes on XRD patterns. The reaction has been bracketed at 1.65 GPa at 1100 °C with > 12 wt% Al2O3 in Opx; 2.05 GPa at 1000 °C with 10 wt% Al2O3 in Opx; and 2.4 GPa at 930 °C with 5 wt% Al2O3 in Opx. The reaction boundary is slightly curved to higher P with increasing T caused by increasing Al in Opx. The boundary observed in this study is about 100 °C or 0.4 GPa higher than previously proposed by Hensen & Essene (1971) and 70-170 °C or 0.6-0.7 GPa higher than the boundary calculated in this system using THERMOCALC ds6.22 (Holland & Powell, 2011, J. Meta. Geol.) and about 1-4 wt% higher Al2O3 contents in Opx. Higher pressure runs in the field

Experimental evidence for excess entropy discontinuities in glass-forming solutions.

Glass transition temperatures T(g) are investigated in aqueous binary and multi-component solutions consisting of citric acid, calcium nitrate (Ca(NO(3))(2)), malonic acid, raffinose, and ammonium bisulfate (NH(4)HSO(4)) using a differential scanning calorimeter. Based on measured glass transition temperatures of binary aqueous mixtures and fitted binary coefficients, the T(g) of multi-component systems can be predicted using mixing rules. However, the experimentally observed T(g) in multi-component solutions show considerable deviations from two theoretical approaches considered. The deviations from these predictions are explained in terms of the molar excess mixing entropy difference between the supercooled liquid and glassy state at T(g). The multi-component mixtures involve contributions to these excess mixing entropies that the mixing rules do not take into account. © 2012 American Institute of Physics

Modification of the radiation resistance of Aspergillus flavus mycelial units by some chemicals

1977-01-01

Survival curves for the mycelium of Aspergillus flavus Link var. columnaris Raper and Fennell were constructed after irradiation with gamma rays in the presence of NaCl, NaBr, NaI, KCl, KBr, KI, CaCl 2 , CaBr 2 , CaI 2 , Ca(NO 3 ) 2 , NaNO 2 , NaNO 3 , KNO 2 , iodoacetic acid, iodoacetamide and vitamin K 5 . In addition iodized salt was also tested. All the chemicals tested exhibited initial toxicity at zero dose. However, most of the chemicals demonstrated a synergism when present during irradiation. Compounds containing iodine were invariably the strongest radiosensitizers. The iodine present as an admixture in salt also retained its radiosensitizing character. Sodium bromide and calcium bromide behaved in a different way. The initial toxicity was reduced along with an increase in radiation dose resulting in more survival. (orig.) [de

Soil water concentrations of cadmium and zinc were measured in plant pots with 15 contaminated soils which differed in origin, texture, pH (5.1-7.8) and concentrations of cadmium (0.2-17 mg Cd kg(-1)) and zinc (36-1300 mg Zn kg(-1)). The soil waters contained total concentrations of 0.5 to 17 mu g...... to 0.1% per year of the total soil content of cadmium and zinc. The measured soil water concentrations of cadmium and zinc did not correlate linearly with the corresponding soil concentrations but correlated fairly well with concentrations measured in Ca(NO(3))(2) extracts of the soils and with soil...... water concentrations estimated from soil concentrations and pH. Such concentration estimates may be useful for estimating amounts of cadmium and zinc being leached from soils....

It was not a common sale, as those that it carries out the company with the crude of Cusiana or Cano Limon. The new of this shipping is that it was the first successful test of marketing the Colombian heavy crude in the exterior, since previously it was almost considered a curse to find heavy crude by the difficulties of its transport. Today it can be taken to any refinery of the world and the best test is that, after almost a year of efforts to overcome the barriers of the transport, the company achieved its conduction from the Castilla Field, in proximities to Villavicencio, until the Covenas Port, in the Caribbean Colombian coast

Tannic acid assisted synthesis of flake-like hydroxyapatite nanostructures at room temperature

2016-09-01

A simple and non-expensive procedure was performed to synthesize hydroxyapatite (HAp) flake-like nanostructures, by using a co-precipitation method with tannic acid as stabilizing agent at room temperature and freeze drying. Samples were synthesized with two different salts, Ca(NO3)2 and CaCl2. X-ray diffraction analysis, Raman spectroscopy, scanning and transmission electron microscopy characterizations reveal Ca10(PO4)6(OH)2 HAp particles with hexagonal structure and P63/m space group in both cases. In addition, the particle size was smaller than 20 nm. The advantage of this method over the works reported to date lies in the ease for obtaining HAp particles with a single morphology (flakes), in high yield. This opens the possibility of expanding the view to the designing of new composite materials based on the HAp synthesized at room temperature.

The author has identified the following significant results. Lake Apopka and three lakes downstream of it (Dora, Eustis, and Griffin) are in an advanced state of eutrophication with high algal concentrations. This feature has shown up consistently on ERTS-1 images in the form of a characteristic water color for those lakes. As expected, EREP photographs also show a characteristic color for those lakes. What was not expected is that Lake Griffin shows a clear pattern of this coloration. Personnel familiar with the lake believe that the photograph does, indeed, show an algal bloom. It is reported that the algal concentration is often significantly higher in the southern portion of the lake. What the photograph shows that was not otherwise known is the pattern of the algal bloom. A similar, but less pronounced, effect is seen in Lake Tohopekaliga. Personnel stationed at Kissimmee reported that there was an algal bloom on that lake at the time of the EREP pass and that its extent corresponded approximately to that shown on the photograph. Again, the EREP photograph gives information about the extent of the bloom that could not be obtained practically by sampling. ERTS-1 images give some indication of this algal distribution on Lake Griffin in some cases, but are inconclusive.

Surface antigens and potential virulence factors from parasites detected by comparative genomics of perfect amino acid repeats

2007-12-01

Full Text Available Abstract Background Many parasitic organisms, eukaryotes as well as bacteria, possess surface antigens with amino acid repeats. Making up the interface between host and pathogen such repetitive proteins may be virulence factors involved in immune evasion or cytoadherence. They find immunological applications in serodiagnostics and vaccine development. Here we use proteins which contain perfect repeats as a basis for comparative genomics between parasitic and free-living organisms. Results We have developed Reptile http://reptile.unibe.ch, a program for proteome-wide probabilistic description of perfect repeats in proteins. Parasite proteomes exhibited a large variance regarding the proportion of repeat-containing proteins. Interestingly, there was a good correlation between the percentage of highly repetitive proteins and mean protein length in parasite proteomes, but not at all in the proteomes of free-living eukaryotes. Reptile combined with programs for the prediction of transmembrane domains and GPI-anchoring resulted in an effective tool for in silico identification of potential surface antigens and virulence factors from parasites. Conclusion Systemic surveys for perfect amino acid repeats allowed basic comparisons between free-living and parasitic organisms that were directly applicable to predict proteins of serological and parasitological importance.

Visual communication in the psychoanalytic situation.

Kanzer, M

1980-01-01

The relationship between verbal and visual aspects of the analytic proceedings shows them blended integrally in the experiences of both patient and analyst and in contributing to the insights derived during the treatment. Areas in which the admixture of the verbal and visual occur are delineated. Awareness of the visual aspects gives substance to the operations of empathy, intuition, acting out, working through, etc. Some typical features of visual 'language" are noted and related to the analytic situation. As such they can be translated with the use of logic and consciousness on the analyst's part, not mere random eruptions of intuition. The original significance of dreams as a royal road to the unconscious is confirmed-but we also find in them insights to be derived with higher mental processes. Finally, dyadic aspects of the formation and aims of dreams during analysis are pointed out, with important implications for the analyst's own self-supervision of his techniques and 'real personality" and their effects upon the patient. how remarkable that Dora's dreams, all too belatedly teaching Freud about their transference implications, still have so much more to communicate that derives from his capacity to record faithfully observations he was not yet ready to explain.

Next-Generation Metrics: Responsible Metrics & Evaluation for Open Science

Energy Technology Data Exchange (ETDEWEB)

Wilsdon, J.; Bar-Ilan, J.; Peters, I.; Wouters, P.

2016-07-01

Metrics evoke a mixed reaction from the research community. A commitment to using data to inform decisions makes some enthusiastic about the prospect of granular, real-time analysis o of research and its wider impacts. Yet we only have to look at the blunt use of metrics such as journal impact factors, h-indices and grant income targets, to be reminded of the pitfalls. Some of the most precious qualities of academic culture resist simple quantification, and individual indicators often struggle to do justice to the richness and plurality of research. Too often, poorly designed evaluation criteria are “dominating minds, distorting behaviour and determining careers (Lawrence, 2007).” Metrics hold real power: they are constitutive of values, identities and livelihoods. How to exercise that power to more positive ends has been the focus of several recent and complementary initiatives, including the San Francisco Declaration on Research Assessment (DORA1), the Leiden Manifesto2 and The Metric Tide3 (a UK government review of the role of metrics in research management and assessment). Building on these initiatives, the European Commission, under its new Open Science Policy Platform4, is now looking to develop a framework for responsible metrics for research management and evaluation, which can be incorporated into the successor framework to Horizon 2020.

To describe the pattern of injuries and illnesses sustained during the Games of the XXXI Olympiad, hosted by Rio de Janeiro from 5 to 21 August 2016. We recorded the daily incidence of athlete injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the Rio 2016 medical staff. In total, 11 274 athletes (5089 women, 45%; 6185 men, 55%) from 207 NOCs participated in the study. NOC and Rio 2016 medical staff reported 1101 injuries and 651 illnesses, equalling 9.8 injuries and 5.4 illnesses per 100 athletes over the 17-day period. Altogether, 8% of the athletes incurred at least one injury and 5% at least one illness. The injury incidence was highest in BMX cycling (38% of the athletes injured), boxing (30%), mountain bike cycling (24%), taekwondo (24%), water polo (19%) and rugby (19%), and lowest in canoe slalom, rowing, shooting, archery, swimming, golf and table tennis (0%-3%). Of the 1101 injuries recorded, 40% and 20% were estimated to lead to ≥1 and >7 days of absence from sport, respectively. Women suffered 40% more illnesses than men. Illness was generally less common than injury, with the highest incidence recorded in diving (12%), open-water marathon (12%), sailing (12%), canoe slalom (11%), equestrian (11%) and synchronised swimming (10%). Illnesses were also less severe; 18% were expected to result in time loss. Of the illnesses, 47% affected the respiratory system and 21% the gastrointestinal system. The anticipated problem of infections in the Rio Olympic Games did not materialise, as the proportion of athletes with infectious diseases mirrored that of recent Olympic Games (3%). Overall, 8% of the athletes incurred at least one injury during the Olympic Games, and 5% an illness, which is slightly lower than in the Olympic Summer Games of 2008 and 2012. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Cadmium and Zn availability as affected by pH manipulation and its assessment by soil extraction, DGT and indicator plants

International Nuclear Information System (INIS)

Muhammad, Iqbal; Puschenreiter, Markus; Wenzel, Walter W.

2012-01-01

Manipulation of soil pH by soil additives and / or rhizosphere processes may enhance the efficiency of metal phytoextraction. Here we report on the effect of nitric acid additions to four polluted soils on Cd and Zn concentrations in soil solution (C soln ) and 0.005 M Ca(NO 3 ) 2 extracts, and related changes in the diffusive fluxes and resupply of the metals as assessed by diffusive gradients in thin films (DGT). The responses of these chemical indicators of bioavailability were compared to metal uptake in two indicator plant species, common dandelion (Taraxacum officinale F.H. Wigg) and narrow leaf plantain (Plantago lanceolata L.) grown for 75 days in a pot experiment. Lowering soil pH increased C soln , the 0.005 M Ca(NO 3 ) 2 -soluble fractions and the DGT-measured Cd and Zn concentrations (C DGT ) in the experimental soils. This was associated with enhanced uptake of Cd and Zn on soils acidified to pH 4.5 whereas plants did not survive at pH 3.5. Toxicity along with decreased kinetics of metal resupply (calculated by the 2D DIFS model) in the strong acidification treatment suggests that moderate acidification is more appropriate to enhance the phytoextraction process. Each of the chemical indicators of bioavailability predicted well (R 2 > 0.70) the Cd and Zn concentrations in plantain shoots but due to metal toxicity not for dandelion. Concentration factors, i.e. the ratio between metal concentrations in shoots and in soil solution (CF) indicate that Cd and Zn uptake in plantain was not limited by diffusion which may explain that DGT did not perform better than C soln . However, DGT is expected to predict plant uptake better in diffusion-limited conditions such as in the rhizosphere of metal-accumulating phytoextraction crops. - Highlights: ► The effect of soil acidification was assessed for four Zn and Cd polluted soils. ► For some soils moderate acidification could enhance the metal uptake efficiency. ► Chemical assessment of bioavailability using

Highlights: • Ni(NO 3 ) 2 , Ca(NO 3 ) 2 , Co(NO 3 ) 2 and Fe(NO 3 ) 3 were investigated for HTL of pinewood. • Ni(NO 3 ) 2 showed higher selectivity for H 2 and biocrude generation. • O/C ratio of LBO, HBO and residue recovered was lower than O/C of the pinewood. • HHVs of LBO, HBO and residue were found to be higher than HHV of the pinewood. - Abstract: This study reports hydrothermal liquefaction (HTL) of pinewood at 200–275 °C for H 2 , biocrude and bio-oil production in presence of a nitrate salt catalyst: Ni(NO 3 ) 2 , Ca(NO 3 ) 2 , Co(NO 3 ) 2 and Fe(NO 3 ) 3 . Among these catalysts, Ni(NO 3 ) 2 showed higher selectivity towards H 2 and biocrude generation. To generate H 2 and biocrude, a slurry of pinewood was prepared with different biomass to solvent (B:S) ratios of 1:10, 1:30, and 1:75 and loaded in the SS316 PARR reactor and heated to different temperatures. While the reaction was in progress, gas samples were withdrawn and analyzed using GC equipped with Chrompack capillary column and thermal conductivity detector. The analysis of product gas revealed the presence of H 2 , CO 2 , CO and CH 4 . The liquid samples collected during the reaction were centrifuged to separate residue and analyzed using TOC analyzer, HPLC and GC–MS. Among different homogeneous catalysts used, Ni(NO 3 ) 2 yielded 12.26 mol% H 2 at 275 °C and a maximum biocrude of 55 wt% at 250 °C using 200 psi N 2 partial pressure. The biocrude was found to contain sugars, C 1 -C 3 carboxylic acids such as lactic, propionic, acetic and formic, HMF/furfural and other oxygenated compounds, which were thoroughly analyzed by GC–MS. Among different C 1 -C 3 acids, lactic acid was observed in the major amount of 83.92 wt% using B:S of 1:75 at 250 °C. The biocrude obtained was further processed to recover light bio-oil (LBO), heavy bio-oil (HBO) and residue which were found to have higher heating value (HHV) as compared with original pinewood

PEEK/nHA composite material, with excellent mechanical property as polyetheretherketone (PEEK) and biological activity as hydroxyapatite (HA), has attracted wide attention of medical experts and materials science experts. The addition of hydroxyapatite was the decisive factor for biological activity in PEEK/nHA composite. In this paper, acicular nanohydroxyapatite was prepared by chemical precipitation method with Ca(NO3)2, (NH4)2HPO4 as raw material; PEEK/nHA composite was prepared by solution blending and vacuum sintering method. The composite was characterized with FT-IR, XRD, DSC, TG and mechanical property test. Results showed that the composite has good thermal stability and compressive property when the mass ratio of PEEK to nHA is 10:3; and high nHA content can improve the biological activity of the composite, which can meet the basic requirements for bone tissue engineering scaffold.

The incorporation of Sr2+ and Mg2+ ions into apatite favors the mineralization process of the bone, besides it to prevent the osteoporosis. In this work, it was evaluated the individual effect of Sr2+ and Mg2+ ions in the electrochemical deposition process of calcium phosphate on metallic substrate. The electrodeposition was performed using a conventional three- electrode cell. The titanium sheets were immersed in the electrolyte containing Ca(NO3)2 and NH4H2PO4 and a potential of -0. 8 V was applied. The coatings were characterized by SEM and XRD. By XRD analysis was possible to identify octacalcium phosphate in the control sample. However, after the addition of Mg2+ ions the OCP becomes the secondary phase while the brushite showed as majoritary phase. On the other hand, the incorporation of Sr2+ ions stabilized the OCP phase.

Price, Colin G.; Murphy, Brian P.

2002-12-01

On 4 July 1999, a severe convective windstorm, known as a derecho, caused extensive damage to forested regions along the United States/Canada border, west of Lake Superior. There were 665,000 acres of forest destroyed in the Boundary Waters Canoe Area Wilderness (BWCAW) in Minnesota and Quetico Provincial Park in Canada, with approximately 12.5 million trees blown down. This storm resulted in additional severe weather before and after the occurrence of the derecho, with continuous cloud-to-ground (CG) lightning occurring for more than 34 hours during its path across North America. At the time of the derecho the percentage of positive cloud-to-ground (+CG) lightning measured by the Canadian Lightning Detection Network (CLDN) was greater than 70% for more than three hours, with peak values reaching 97% positive CG lightning. Such high ratios of +CG are rare, and may be useful indicators of severe weather.

Full Text Available This paper is part of the doctoral thesis entitled “Critique of translation for film dubbing and subtitling from the perspective of discourse analysis. A study applied to "The Green Mile”, written by Ph.D. student Gabriela Saturnina Alanís Uresti, directed by Ph.D. Lidia Rodríguez. It is a qualitative and descriptive study where we contrasted The Green Mile - a 1999 Hollywood film, original in American English - with its translated versions: dubbed and subtitled into Spanish of Mexico. We start from the presupposition that in film translation, some references such as the ones related to sexual behaviors and offensive language are attenuated in order to be strategically polite. Specifically, we analyzed two mechanisms of attenuation: lexical selection whereby a euphemism is used, and discursive modalization. These mechanisms constitute strategies of linguistic, pragmatic and semiotic nature as they appear in original (OV, dubbed (DV and subtitled (SV versions; both in acoustic and visual channels. Therefore, we examine these occurrences on verbal, para-verbal, and non-verbal codes. The theoretical basis includes studies of attenuation, politeness, euphemisms, and linguistic taboos.

The starting solution with the Ca/P ratio of 1.67 was prepared by mixing 0.167 mol·dm-3 Ca(NO3)2·4H2O, 0.100 mol·dm-3 (NH4)2HPO4, 0.500 mol·dm-3 (NH2)2CO and 0.10 mol·dm-3 HNO3 aqueous solutions. The hydroxyapatite were prepared by heating the solution at 80 °C for 24 hour and then at 90°C for 72 hour. Then followed, the dry powers were heat treatment at 660°C temperatures for 8 hour. The obtained powder was analyzed using XRD, XRF, FT-IR, SEM, TG-DTA. The results showed that obtained HAp powers were greatly influenced by synthetic conditions. HAp powders with various morphologies, such as sphere, rod, layered, dumbbell, fibre, scaly, were obtained by controlling the synthetic conditions.

The study of the ph effect is presented on thermoluminescent response of calcium phosphates synthesized by precipitation process. For the synthesis by precipitation, were used: calcium nitrate (Ca(NO 3 ) 2 and ammonium phosphate dibasic ((NH 4 ) 2 HPO 4 ) as precursors. Samples were obtained at ph 7, 8, 9 and 10 and subjected to a calcination s temperature of 1100 C. Samples were also irradiated with X rays of 6 MV to a dose of 2 Gy. Samples prior to irradiation showed no luminescence, the irradiated samples displayed a luminescent curve which is due to the X-ray response. Powders synthesized at ph 7 showed a well-defined peak centered at 267 grades C. The rest of the prepared samples showed a luminescent curve composed of several peaks. By analyzing the curve at ph 7 by the method of the shape of the curve, was found to have an order of 1.7, with an activation energy, E = 1.44 ± 0.04 eV. (Author)

2016-10-01

We present the study of the structural characterization and the thermoluminescent response of the hydroxyapatite as a function of the calcination temperature and the effect of the particle size. For precipitation synthesis, calcium nitrate (Ca(NO_3)_2 and dibasic ammonium phosphate ((NH_4)_2HPO_4) were used as precursors and ammonium hydroxide (NH_4OH) as a ph controlling agent. The characterization of the samples was carried out by the techniques of X-ray diffraction, scanning electron microscopy and infrared spectroscopy. The powders obtained are composed of hydroxyapatite, with a different degree of dehydroxylation. The thermoluminescent characterization indicates that at higher calcination temperature there is a higher thermoluminescent response, the calcined powders at 1300 degrees Celsius show a very well defined brightness curve with a higher intensity, with its maximum intensity located at a temperature of 210 degrees Celsius, which indicates that this material can be used as a dosimeter.

Empirical research provides contradictory evidence of the loss of traditional ecological knowledge across societies. Researchers have argued that culture, methodological differences, and site-specific conditions are responsible for such contradictory evidences. We advance and test a third explanation: the adaptive nature of traditional ecological knowledge systems. Specifically, we test whether different domains of traditional ecological knowledge experience different secular changes and analyze trends in the context of other changes in livelihoods. We use data collected among 651 Tsimane' men (Bolivian Amazon). Our findings indicate that different domains of knowledge follow different secular trends. Among the domains of knowledge analyzed, medicinal and wild edible knowledge appear as the most vulnerable; canoe building and firewood knowledge seem to remain constant across generations; whereas house building knowledge seems to experience a slight secular increase. Our analysis reflects on the adaptive nature of traditional ecological knowledge, highlighting how changes in this knowledge system respond to the particular needs of a society in a given point of time.

Beyond the Brink: Indigenous Women’s Agency and the Colonisation of Knowledge in the Maid of the Mist Myth

Directory of Open Access Journals (Sweden)

Robinder Kaur Sehdev

2012-11-01

Full Text Available The myth of the Maid of the Mist of Niagara Falls is a settler story of an Indigenous woman who kills herself by piloting her canoe over the cataract. This is presented not as a tragedy, but as a cultural necessity. So compelling was this settler myth that until recently it was the focus of settler cultural production at Niagara. I argue that the creation and subsequent fixation upon the myth attempted to displace Indigenous stories, and the centrality of Indigenous women to Indigenous epistemologies and in decolonial action. The recent move to banish the myth from tourist audiences does further violence by moving colonial cultural production to the fringes of visibility and away from critical interrogation. The myth and the ways it is called upon and subsequently banished indicates the normalizing practices of settler colonialism and must be pulled from the brink of unnameability and unknowability into critical discourse.

Natural mineral dust and heavy anthropogenic pollution and its complex interactions cause significant environmental problems in East Asia. Due to restrictions of observing technique, real-time morphological change in Asian dust particles owing to coating process of anthropogenic pollutants is still statistically unclear. Here, we first used a newly developed, single-particle polarization detector and quantitatively investigate the evolution of the polarization property of backscattering light reflected from dust particle as they were mixing with anthropogenic pollutants in North China. The decrease in observed depolarization ratio is mainly attributed to the decrease of aspect ratio of the dust particles as a result of continuous coating processes. Hygroscopic growth of Calcium nitrate (Ca(NO3)2) on the surface of the dust particles played a vital role, particularly when they are stagnant in the polluted region with high RH conditions. Reliable statistics highlight the significant importance of internally mixed, `quasi-spherical' Asian dust particles, which markedly act as cloud condensation nuclei and exert regional climate change.

1989-01-01

Chronic and acute effects of L-Carnitina (vials of 1 g L-Carnitina endovenous; per orally administered vials of 1 g L-Carnitina; tablets of 1 g L-Carnitina) were recorded in 110 top athletes (rowing, kayak-canoe, swimming, weightlifting medium and long-distance runners), 47 girls and 63 boys, by six double blind placebo trials and cross over. Significant changes were registered after L-Carnitina treatment (both for a single dose or after 3 weeks of treatment) compared to placebo, for FFA, triglycenides, lactic acid after exercise, evoked muscular potential, plasma carnitine (free and acetyl-carnitine), urine carnitine (free carnitine) and others. The authors explain these changes by the increase of free carnitine, which permits a larger quantity of FFA to enter the mitochondria and to be more extensively used as energy source in endurance and strength efforts. Based on these results the authors recommend L-Carnitina as an ergogenic aid in elite athletes, especially in endurance and strength sports.

Determination of plutonium in soils by mass spectrometry

International Nuclear Information System (INIS)

Storms, H.A.; Carlson, D.C.; Hunter, F.F.

1974-01-01

A procedure is described in which mass spectrometry is utilized for the determination of plutonium in soils. Using this procedure we have measured plutonium isotopic compositions at concentrations as low as 2 x 10 -14 grams Pu per gram soil. A thermal ionization source with canoe-shaped rhenium filament, is utilized in the mass spectrometer. The plutonium, when loaded onto the filament, is contained in a single Dowex-1 resin bead which is about 350 micrometers in diameter. Concentrating the plutonium within this single bead is a key step in the procedure and produces a relatively clean plutonium fraction. The resin bead also serves as an effective diffusion barrier such that the plutonium is prevented from being removed with the lower boiling impurities. The Pu remains in the bead until the temperature is sufficiently high for efficient production of Pu + ions. Plutonium ionization efficiencies as high as 2.5 percent have been measured

Full text.Homogeneous high temerature superconductor ceramic powder of TI-Ba-Ca-Cu-O with transition temperature [Tc=123K] have been successfully prepared from the mixture of nitrate salts [TlNO 3 , Ba(NO 3 ) 2 , Ca(NO 3 ) 2 .4H 2 O and Cu(NO 3 ) 2 .3H 2 O] by using freeze-drying method. Freeze-dryer that was used in this work designed locally in our laboratory. This technique consider a better to get a fine powder of ceramic materials by depending on the procedure of frozen droplets with present of liquid nitrogen. SEM pictures showed the size of grains of about [0.8 μm]. We conclude that the high sintering temperature, for the prepared powders in this technique, for long time [120 hrs] will increase the inter diffusion between the grains ahich caused the decreasing in the density of the sample which may be given a better results than the obtained in a previous works

Specimens of different types of soil, namely chernozem, brown soil and illimerized soil were taken in the environs of the nuclear power plant construction site. 0.0285 MBq of 85 Sr in chloride form was added. Solutions of NaNO 3 , KNO 3 and Ca(NO 3 ) 2 of different concentrations and their mixtures were used in studying the effect of salts on strontium sorption. The sorption was studied under steady-state conditions. The eluate samples were measured with an NZQ 201 spectrometer. The 85 Sr sorption by soils in the presence of the individual salts and their mixtures was found to depend on the type of soil. The highest 85 Sr sorption value was found for chernozem while a low radiostrontium sorption was observed for brown soil. The reducing effect was confirmed of elevated salt content in the soil on 85 Sr sorption. The results obtained are discussed in detail. (E.S.) 1 tab., 2 figs., 6 refs

2011-07-01

Nano-hydroxyapatite (n-HA) crystalline films have been developed in this study by electrodeposition method on NiTi shape memory alloy (SMA). The electrodeposition of the n-HA films was carried out using 0.042 mol/L Ca(NO3)2 · 4H2O + 0.025 mol/L (NH4) · 2HPO4 electrolytes by applying a constant potential of -2.0 V for 120 min and keeping the solution temperature at 70 °C. The characterization of n-HA films is of special importance since bioactive properties related to n-HA have been directly identified with its specific composition and crystalline structure. AFM, XRD, EDX, FEG-SEM and Raman spectroscopy shows a homogeneous film, with high crystallinity, special composition, and bioactivity properties (Ca/P = 1.93) of n-HA on NiTi SMA surfaces. The n-HA coating with special structure would benefit the use of NiTi alloy in orthopedic applications.

Orexin 1 receptor antagonists in compulsive behaviour and anxiety: possible therapeutic use.

Emilio eMerlo-Pich

2014-02-01

Full Text Available Fifteen years after the discovery of hypocretin/orexin a large body of evidence has been collected supporting its critical role in the modulation of several regulatory physiological functions. While reduced levels of hypocretin/orexin were early on associated with narcolepsy, increased levels have been linked in recent years to pathological states of hypervigilance and, in particular, to insomnia. The filing to FDA of the dual-activity orexin receptor antagonist (DORA suvorexant for the indication of insomnia further corroborates the robustness of such evidences. However, as excessive vigilance is also typical of anxiety and panic episodes, as well as of abstinence and craving in substance misuse disorders, in this review we briefly discuss the evidence supporting the development of hypocretin/orexin receptor 1 (OX1 antagonists for these indications. Experiments using the OX1 antagonist SB-334867 and mutant mice have involved the OX1 receptor in mediating the compulsive reinstatement of drug seeking for ethanol, nicotine, cocaine, cannabinoids and morphine. More recently, data have been generated with the novel selective OX1 antagonists GSK1059865 and ACT-335827 on behavioural and cardiovascular response to stressors and panic-inducing agents in animals. Concluding, while waiting for pharmacologic data to become available in humans, risks and benefits for the development of an OX1 receptor antagonist for Binge Eating and Anxiety Disorders are discussed.

Flood Risk in Australia: Whose Responsibility Is It, Anyway?

Full Text Available This paper presents research into four key stakeholders in flood risk management in Australia: local councils, the insurance industry, the State Emergency Service (SES, and local residents; examining the perception of their own roles and responsibilities, and those of the other stakeholders. Key informant interviews were conducted in four locations—Brisbane and Emerald, in Queensland, Dora Creek, in New South Wales, and Benalla, in Victoria. We find that understanding of the roles and responsibilities of each stakeholder varied considerably between research participants. Insurance representatives felt their concerns about increasing flood risk costs were unheeded until the 2010–2011 floods made them the “canary in the coal mine”. Councils felt they had limited options for reducing flood risk. SES representatives felt they were too relied upon for event response, with requests for assistance outstripping their capacity to assist, and many residents were uncertain how to prepare for flood, relying on emergency agencies and the local council to protect them. Key lessons for flood risk management in Australia are (a an urgent need for all stakeholders to better understand each others’ roles and responsibilities; and (b residents must take greater responsibility for their own personal protection. Only then can the vision of shared responsibility presented by the 2009 National Strategy for Disaster Resilience be achieved.

Freud's 'transference': Clinical technique in the 'Rat Man' case and theoretical conceptualization compared.

Science.gov (United States)

Diercks, Michael

2017-07-31

A considerable gap exists between clinical psychoanalytic concepts and psychoanalytic practice. It can be traced back to the early beginnings of psychoanalysis and to Freud's own handling of concepts that he had developed himself. Focusing on the concept of 'transference' that Freud in several steps coined so precisely from his experiences with hysteric patients and especially from his understanding of the 'Dora' case, it can be shown that he - seen from today - could not fully apply the meaning of his own concept in the later treatment of the so-called 'Rat Man'. Freud's 'Original record of the case' is used to scrutinize his way of understanding and handling the transference with this patient. To a substantial extent transference as well as counter-transference was rather enacted than understood in this case, partly due to Freud's own personal and scientific interests and to his ambitions to use this case as a demonstration of his therapeutic approach. In order to show this, it is unavoidable to correct several blurry or even misleading passages of Strachey's translation. Findings from numerous workshops using 'comparative clinical methods' indicate that up till now we analysts - like Freud - have great difficulties in applying Freud's incredible insight that "a whole series of former psychic experiences comes alive not as the past but as the present relationship to the person of the physician" (Freud, 1905c [1901], p. 279/280, my translation).

Curran, Sabrina C; Haile-Selassie, Yohannes

2016-07-01

Woranso-Mille is a paleoanthropological site in Ethiopia sampling an important and under-represented time period in human evolution (3.8-3.6 million years ago). Specimens of cf. Australopithecus anamensis, Australopithecus afarensis, and the recently named Australopithecus deyiremeda have been recovered from this site. Using multiple habitat proxies, this study provides a paleoecological reconstruction of two fossiliferous collection areas from Woranso-Mille, Aralee Issie (ARI) and Mesgid Dora (MSD). Previous reconstructions based on faunal assemblages have pointed, due to the presence of aepycerotins, alcelaphins, and proboscideans, to the existence of open habitats as well as more closed ones, based on the occurrence of cercopithecids, giraffids, and traglephins. Results from community structure analysis (proportions of locomotor and dietary adaptations) at ARI and MSD indicated a predominance of open habitats, such as shrublands. Mesowear analysis revealed that ungulates of all dietary types (grazers, leaf and fruit browsers, and mixed feeders) were present in nearly equal proportions. Ecomorphological analyses using linear measurements of the astragalus and phalanges indicated that bovids utilizing locomotor behaviors associated with all habitat types were present, though the intermediate-cover habitat bovids were best represented in the sample (Heavy cover at ARI and Light cover at MSD). Together, these results suggest that the ARI and MSD localities were heterogeneous habitats (mosaics), likely with densely vegetated areas along a paleo-river and more open regions (woodlands, grasslands) available away from the river.

Nous avons l'intention de comprendre comment Freud, basé sur l'interface entre le "déterminisme de la période de l'enfance" et la "contingence adolescent", articule la puberté par rapport à l'irruption de la névrose. Nous nous occupons de la pertinence de la "période de latence" et également avec l'hypothèse d'une sexualité "en deux étapes", selon la compréhension de la puberté et de ses possibilités pour la constitution du sujet. Nous utilisons les ressources méthodologiques de certains des principaux cas cliniques analysés par Freud comme Dora, L'homme-aux-loups et La Jeune Homosexuelle. De cette façon, nous avons le but de discuter de la pertinence de l'irruption de la puberté, de ses possibilités et les obstacles dans la causalité/ manifestation d'une névrose. Nous avons réalisé que Freud, tout en ne prenant pas cette question comme l'objet de ses recherches, il l'a explorée au long de ses études, ce qui nous permet de considérer et de discuter de son point de vue sur ce thème.

Two Interlocked Triads in Pat Kinevane’s Recent Plays: Self-Soul-Conscousness and Birth-Death-Rebirth

Full Text Available Everyting conceivable, all that has ever been imagined, can be included in our minds and souls. As psyche means “breath”, “soul” and “mind”, it points to the relevance of psychology as a study of mental, emotional and spiritual processes involved in our identity make-up. One of the main organizers of our self and psychological experiences is our relationhip with death: our fear of abandonement and of being alone when conceiving our own death, the fear of the loss of the others, leading to the fear of attachment and emotional death. Pat Kinevane, a contemporary Irish playright, deals, in his 2005 play, Forgotten, with the idea of family and social abandonment of old people in nursing homes. The interconnected stories of Dora, Eucharia, Flor and Gustus, the characters in the play, aged 80-100 years old, living in separate retirement and care facilities around Ireland, reveal these fears. Mental illness in the current explosion of anxiety is also crucial to our identity. Another play by Kinevane, Silent (2010, ends with the word silent, which indicates the insanity, invisibility and ultimately the death of the protagonist, Tino McGoldring, a homeless man tormented by the suicide of his brother. His self after the loss of his brother, wife, family, job, mind is constructed in relation to the past and the imaginary world of the Italian-American icon of the film industry of the 1920s, Rudolph Valentino.

Hydroxyapatite (HA) particles were synthesized using Ca(NO3)2·4H2O and (NH4)2HPO4 as precursors with varying contents of non-ionic surfactant viz., triton X-100 (organic modifier) via co-precipitation method followed by hydrothermal treatment. The prepared HA particles have been characterized by X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FT-IR), Energy Dispersive X-ray Analysis (EDX), High Resolution Scanning Electron Microscopy (HRSEM), High Resolution Transmission Electron Microscopy (HRTEM) and Nitrogen adsorption-desorption experiments. The XRD and FTIR studies indicate the formation of HA phase in all the synthesized samples. The specific roles of triton X-100 and hydrothermal treatment in dispersing and in directing the crystal growth respectively have been discussed by comparing the observations from individual experiments using triton X-100 and hydrothermal treatment with that of combined protocol involving both. The plausible mechanism for the individual roles of both triton X-100 and hydrothermal treatment have been proposed. Copyright © 2016 Elsevier B.V. All rights reserved.

Isolation of a 250 million-year-old halotolerant bacterium from a primary salt crystal

Vreeland, Russell H.; Rosenzweig, William D.; Powers, Dennis W.

2000-10-01

Bacteria have been found associated with a variety of ancient samples, however few studies are generally accepted due to questions about sample quality and contamination. When Cano and Borucki isolated a strain of Bacillus sphaericus from an extinct bee trapped in 25-30 million-year-old amber, careful sample selection and stringent sterilization techniques were the keys to acceptance. Here we report the isolation and growth of a previously unrecognized spore-forming bacterium (Bacillus species, designated 2-9-3) from a brine inclusion within a 250million-year-old salt crystal from the Permian Salado Formation. Complete gene sequences of the 16S ribosomal DNA show that the organism is part of the lineage of Bacillus marismortui and Virgibacillus pantothenticus. Delicate crystal structures and sedimentary features indicate the salt has not recrystallized since formation. Samples were rejected if brine inclusions showed physical signs of possible contamination. Surfaces of salt crystal samples were sterilized with strong alkali and acid before extracting brines from inclusions. Sterilization procedures reduce the probability of contamination to less than 1 in 10 9.

The marine ecosystems of the South Pacific coast of Costa Rica: state of knowledge and management perspectives

International Nuclear Information System (INIS)

Quesada Alpizar, Marco A.; Cortes, Jorge

2006-01-01

A review of the existing scientific literature on marine ecosystems in the South Pacific of Costa Rica is presented. Most of the information generated to date concentrates on the Golfo Dulce area, a tropical fiord and only anoxic basin in the American pacific coast. Even thought there is a considerable amount of information available, there are still many aspects of the marine ecosystems of the region that remain unstudied. Among these, those concerning circulation patterns, mangrove dynamics, biodiversity of soft sediments and deep waters, and the ecology of commercially important species of mollusks, crustaceans and fish, stand out. Special attention should be placed on the study of Golfo Dulce, Isla del Cano and the Terraba-Sierpe mangrove system, give their biological importance and unique regional character. Coastal management in the region should be based on the best scientific information available integrating biological, social and economic criteria; and seeking the improvement of inter-institutional coordination in order to achieve integrative solutions to the existing threats to marine resources.

Progress and plans for the EnCurrent power generation system

Energy Technology Data Exchange (ETDEWEB)

Bear, C. [New Energy Corp. Inc., Calgary, AB (Canada)

2008-07-01

This presentation discussed a new vertical axis hydro turbine designed by New Energy Corporation. The EnCurrent turbine design was based on the Darrieus wind turbine, and suited for use in rivers, irrigation canals, industrial outflows, and tidal current applications. The turbine has a flexible deployment configuration with a variable aspect ratio. Designs for the turbine were initiated in fresh water applications, and the size of the equipment was increased to include tidal applications and large river arrays after the technology was proven. A study has demonstrated that use of the turbines in Canada's canal systems would result in significant annual power generation revenues. The use of smaller turbine systems can provide indirect sales to owners through local resellers, while larger systems can provide power or additional revenues for utilities, large cooperatives, and project developers. Case studies of small turbine installations were provided, as well as case studies of turbines used by larger commercial plants. The presentation also discussed several large projects recently undertaken by the company, including the $6.5 million Canoe pass installation. tabs., figs.

A Black Phosphate Conversion Coating on Steel Surface Using Antimony(III)-Tartrate as an Additive

Science.gov (United States)

Li, Feng; Wang, Guiping

2016-05-01

A novel black phosphate conversion coating was formed on steel surface through a Zn-Mn phosphating bath containing mainly ZnO, H3PO4, Mn(H2PO4)2, and Ca(NO3)2, where antimony(III)-tartrate was used as the blackening agent of phosphatization. The surface morphology and composition of the coating were characterized by scanning electron microscopy, energy dispersion spectroscopy, and x-ray photoelectron spectroscopy. Corrosion resistance of the coating was studied by potentiodynamic polarization curves and electrochemical impedance spectroscopy. The pH value of the solution had significant influence on the formation and corrosion resistance of the coating. The experimental results indicated that the Sb plays a vital role in the blackening of phosphate conversion coating. The optimal concentration of antimony(III)-tartrate in the phosphating bath used in this experiment was 1.0 g L-1, as higher values reduced the corrosion resistance of the coating. In addition, by saponification and oil seals, the corrosion duration of the black phosphate coating in a copper sulfate spot test can be as long as 20 min.

2017-08-01

Full Text Available This experiment was conducted experimentally to synthesize Calcia Partially Stabilized Zirconia (Ca-PSZ by sol-gel method using eggshell membrane template as a composite filler. The eggshell membrane was used to produce a mesh shaped structure, which hopefully can improve the mechanical properties of the composite. Ca-PSZ filler was synthesized from ZrOCl2 precursor and Ca(NO32 stabilizer with a 24 hours immersion time. Ca-PSZ of synthesis then mixed with the resin matrix to test its composite hardness. The EDS characterization results suggested that the sample contained elements of zirconia, calcium, and oxygen. Whereas, the XRD characterization identified that crystal structures that formed in the sample were nano scale tetragonal. Characterization of SEM showed Ca-PSZ with mesh structured. The average composite hardness value was 15.79 VHN. The composites with Ca-PSZ-synthesized filler could be prepared and its hardness value was higher than the composite with Ca-PSZ filler in spherical particles, but the hardness was still below the composite on the market.

Full Text Available Las obras literarias escritas por colombianas a principios del siglo XX son hoy casi desconocidas. Ignoramos quiénes eran las escritoras, su estilo y sus temas, pues sus obras aparecieron en revistas o libros de ediciones limitadas y nunca fueron reeditadas. En contraste con la indiferencia del presente, resulta notorio y sorprendente el interés de las mujeres por la literatura y de los lectores por la producción de las mujeres en Antioquia en la época citada, como lo demuestran la gran cantidad de poemas y escritos en prosa firmados por mujeres en las publicaciones culturales de Medellín, desde los tiempos de Agripina Montes del Valle.

2006-01-01

Within an extensive multinational and multidisciplinary project carried out in Donana National Park (Spain) to investigate its preservation and regeneration, the filling velocity of the salt marshes has been evaluated through the calculation of their average sediment accumulation rates. 239+24 Pu and 137 Cs from weapons testing fallout and total 21 Pb distribution profiles and inventories have been determined in some of the most characteristic zones of the park, namely, the ponds (or 'lucios') and the waterjets (or 'canos'). Plutonium inventories range from 16 to 101 Bq m -2 , 137 Cs values fluctuate between 514 and 3758 Bq m -2 and unsupported 21 Pb values comprise between 124 and 9398 Bq m -2 . Average sedimentation rates range from 3 to 5 mm y -1 (1952-2002). These data are higher than those obtained by carbon dating for the period 6500 AD-present, estimated as 1.5-2 mm y -1 , suggesting an increase in the accumulation of sediments and the alteration of the park's hydrodynamics caused by the re-channeling of the major rivers feeding the salt marshes

Investigations of anthropogenic sediments in Qaranilaca, Vanuabalavu Island, Fiji

Nunn, P.D.; Matararaba, S.; Ramos, J.

2000-01-01

Fieldwork throughout the Vanuabalavu group of islands in northeast Fiji in July 1999 by a team from the University of the South Pacific and the Fiji Museum focused on locating evidence for early (Lapita-age) settlement largely through the collection of potsherds from the surface and in test pits. Another site of especial interest was the large cave named Qaranilaca or 'sail cave' (qara = cave, laca = sail) at the southernmost tip of the main island, Vanuabalavu. The oral tradition states that a man named Ravuravu from Totoya Island in southeast Fiji travelled by outrigger canoe (takia) to Vanuabalavu and, upon arrival, put his sail in this cave to dry before going on to club a hunchbacked man to death farther north. It was originally hoped that the extraordinarily voluminous anthropogenic fill of Qaranilaca might contain a record of human occupation extending back further than the last millenium. Although 14 C dating has demonstrated this not to be so, there is undoubtedly a complex story preserved here which is worthy of more detailed excavation than was possible on this occasion. 10 refs., 3 figs

Full Text Available Abstract Traditionally, japanesse martial arts had, as well as technical and tactical lessons, discourses of peace and non-violence. Therefore, this study wants to prove whether the practitioners of these martial arts declare lower levels of attitude toward violence than non-practitioners. To this end, we administered he Brief Scale of Violence in Adolescents (Tejero-González, Balsalobre-Fernández and Ibanez-Cano, in press to two groups of boys and girls from 12 to 17 years of age: one group of judo, karate or jiujitsu (n = 57, and a control one (n = 57. Statistical analysis confirmed that martial arts practitioners declare significantly lower leves than the control group, both in general violence as gratuitous violence, but were not in violence linked to self-protection. Finally, we discuss the influence that factors such as years of practice or competitive orientation may have on the ability of the japanese martial arts to reduce levels of violence. Keywords: martial arts, judo, karate, jiujitsu, violence, adolescents.

Zhao, Qinghe; Mao, Zhengwei; Gao, Changyou; Shen, Jiacong

2006-01-01

Multilayer microcapsules were fabricated by layer-by-layer (LbL) assembly of natural polysaccharides onto CaCO3 particles, following with core removal. The micron-sized CaCO3 particles were synthesized by reaction between Ca(NO3)2 and Na2CO3 solutions in the existence of carboxylmethyl cellulose (CMC). The incorporated amount of CMC in the CaCO3 particles was found to be 5.3 wt% by thermogravimetric analysis. Two biocompatible polysaccharides, chitosan and sodium alginate were alternately deposited onto the CaCO3(CMC) templates to obtain hollow microcapsules. Regular oscillation of surface charge as detected by zeta potential demonstrated that the assembly proceeded surely in a LbL manner. The stability of the microcapsules was effectively improved by cross-linking of chitosan with glutaraldehyde. The chemical reaction was verified by infrared spectroscopy. The microcapsules thus fabricated could be spontaneously filled with positively charged low molecular weight substances such as rhodamine 6G and showed good biocompatibility, as detected by in vitro cell culture.

Elastic-plastic fracture mechanics analysis of a pressure vessel with an axial outer surface flaw. Pt. 2

Brocks, W.; Kuenecke, G.

1989-06-01

Continuing preceding investigations, a further elastic-plastic finite element analysis of a test vessel with a semi-elliptical axial outer surface crack has been performed. The variations of J and CTOD along the crack front and the stress state in the vicinity of the crack are presented. The applicability of analytical approaches to determine J is examined. The FE results are used to analyze the experimental data with respect to the validity of J-controlled crack growth. Local J R -curves of the surface flaw are compared with J R -curves of various specimens of different geometries. Again, it became evident that the local ductile crack growth and, especially, the developing 'canoe shape' of the surface crack cannot be described by a single resistance curve which is assumed to be a material property. A method described in a previous report to predict the ductile crack growth by using local J R -curves which depend on the triaxiality of the stress state did not result in a satisfactory outcome, in the present case. The presumed reasons will be discussed. (orig.) [de

Evaluation of cyclonic ash, commercial Na-silicates, lime and phosphoric acid for metal immobilisation purposes in contaminated soils in Flanders (Belgium)

In order to reduce the health risks associated with historically enriched metal smelting sites in Flanders (Belgium), the capacities of a non-beringite cyclonic ash and commercial Na-silicates to fix metals and create conditions to restore vegetation cover were evaluated and compared to lime and H 3 PO 4 . All tested amendments reduced Ca(NO 3 ) 2 -extractable soil metal concentrations and reduced metal uptake in Agrostis capillaris seedlings. Sodium released by Na-silicates was possibly toxic to bean plants while an isotopic dilution technique revealed that metals were only weakly sorbed by silicates (i.e. reversible sorption). Cyclonic ash appeared more efficient than lime in both reducing oxidative stress in beans and Zn, Cu and Pb uptake in grasses. The metal fixing mechanism for both amendments appeared similar (i.e. irreversible fixation at constant pH), in contrast to H 3 PO 4 where at least part of the immobilised Cd was irreversibly fixed across a range of pH. - Metal immobilising capacities of Na-silicates are weak, while the active mechanism of cyclonic ash is the same as lime

Chondroitin sulfate template-mediated biomimetic synthesis of nano-flake hydroxyapatite

He, Dan; Xiao, Xiufeng; Liu, Fang; Liu, Rongfang

2008-11-01

By Ca(NO 3) 2·4H 2O and (NH 4) 3PO 4·3H 2O as reagents and chondroitin sulfate (ChS) as a template, nano-flake hydroxyapatite (HA) is synthesized using a biomimetic method according to the biomineralization theory. HA crystals obtained are characterized in crystalline phase, microstructure, chemical composition and morphology by X-ray diffraction (XRD), Fourier transform infrared spectroscope (FTIR), transmission electron microscopy (TEM) and elemental analysis respectively. UV-vis spectrum is adopted to investigate interactions between functional groups ChS and HA. The results show that HA crystal nucleation and growth take place in chemical interactions between HA crystals and ChS as a template. And elemental analysis indicates that obtained HA contains a small amount of ChS. Furthermore, ChS concentration significantly affects the morphology of HA crystals. Staple-fiber-like HA crystals can be obtained at a low concentration in ChS, and flake-like HA crystals synthesized at a high concentration (≥0.5 wt.%) of ChS as a template.

Full Text Available After the political rancor left by the XIX century country’s civil wars, especially by the One-Thousand-Days War, the “Reyista Press” was born. This press was President Rafael Reyes’s incense burner and an opposition instrument to the ‘Quinquenio regime’ characterized by a satiric, incendiary and polemic tone, which, at the same time, was the continuation of a rich tradition. Once the ‘Quinquenio regime’ was overthrown, three political forces gain momentum within the Liberal Press: The Republican Press–that supported the presidential nomination of journalist Carlos E. Restrepo–with Alfonso Villegas Restrepo, Eduardo and Enrique Santos Montejo, Enrique Olaya Herrera and the Cano family; the ‘Bloquista’ Press, lead by General Rafael Uribe Uribe; and the Opposite Press with Benjamín Palacio Uribe, founder of Gil Blas newspaper in 1910. Due to its investigative spirit, Gil Blas newspaper served as an inspiration for Colombian contemporary journalism of the Bicentennial. With this satirical poster, the saints of the Republican Press fell off their shelves in this so-called ‘Indigenous Athens.’

Some behavioral and ecological aspects were observed in a remaining population of Crocodylus intermedius found in a Colombian region called Arauca, in the rivers Cravo Norte, Ele, Lipa, Casanare and Cano Matepalma. The behaviors during the daily activity were different among the adult animals studied. These surveys were carried out during the dry season in 1994 and 1995. Behaviors of nesting and parental care were observed. The nesting period took place from late December in 1994 to mid January in 1995. The crocodilian eggs hatched from mid march to the beginning of April. According to the data collected, the clutch size for this region is 20 to 34 eggs. Seven zones of clutching were found. Big holes, observed after the hatching, suggest that maybe the female crocodiles open the nest when the young are emerging from the eggs. The group of animals found is placed in a zone, which has optimal biotic and a biotic aspects. However the inhabitants of this region are an enormous pressure factor upon Crocodylus intermedius

The experimental design was randomized blocks with ten treatments (genotypes of Jatropha curcas, and three replications in row plots of six plants, with a single border and spacing of 3.0 x 2.0 m. Plants were fertilized with 150 g of NPK (06:24:12 at planting time, and a topdressing with 150 g.planta-1 NPK (10:10:10 applied at six and twelve months of age. The plants were irrigated weekly using a dripping system with an average water application of 20 l.plant-1 during the dry period of the region. At 24 months of age, the overall height of the plants, the average diameter of bifurcations at 1.30m from the soil level and the number of bifurcations at 0.5 m of height were evaluated. Twenty six fruit/ seed harvests were done weekly. Fruits were harvested ripe, before falling on the ground, for seven months. To determine dry biomass, the plants were cut at 0.30 m from soil level. The genotypes showed high agronomic uniformity, except for the variable number of bifurcations, where the genotype 1701 was superior to the genotypes 1501, 1602, 1703 and 1601. Biomass production of genotypes in irrigated conditions in the semiarid region is high and the distribution of biomass followed the decreasing order: root>fruit>thick branches>leaves>bark>thin branches.

Expedition Zenith: Experiences of eighth grade girls in a non-traditional math/science program

Science.gov (United States)

Ulm, Barbara Jean

2004-11-01

This qualitative study describes the experiences of a group of sixteen, eighth grade girls participating in a single-sex, math/science program based on gender equity research and constructivist theory. This phenomenological case study highlights the individual changes each girl perceives in herself as a result of her involvement in this program which was based at a suburban middle school just north of New York City. Described in narrative form is what took place during this single-sex program. At the start of the program the girls worked cooperatively in groups to build canoes. The canoes were then used to study a wetland during the final days of the program. To further immerse the participants into nature, the girls also camped during these final days. Data were collected from a number of sources to uncover, as fully as possible, the true essence of the program and the girls' experiences in it. The data collection methods included direct observation; in-depth, open-ended interviews; and written documentation. As a result of data collection, the girls' perceived outcomes and assessment of the program, as well as their recommendations for future math/science programs are revealed. The researcher in this study also acted as teacher, directing the program, and as participant to better understand the experiences of the girls involved in the program. Thus, unique insights could be made. The findings in this study provide insight into the learning of the participants, as well as into the relationships they formed both inside and outside of the program. Their perceived experiences and assessment of the program were then used to develop a greater understanding as to the effectiveness of this non-traditional program. Although this study echoed much of what research says about the needs of girls in learning situations, and therefore, reinforces previously accepted beliefs, it also reveals significant findings in areas previously unaddressed by gender studies.

Treatments were as follow: Control, with no extra N added; Urea = 100 mg N.kg-1 soil as Urea; NO3- = 100 mg N.kg-1 soil as Ca(NO32; and NH4+ = 100 mg N.kg-1 soil as (NH42SO4. It was concluded that: 1 increasing N content in leaves alone was not able to promote gain in biomass production of maté seedlings; 2 seedlings receiving N-NH4 showed a higher accumulation of P and Mg on shoot biomass; and 3 an increase in leaf area, leaf number and net photosynthesis observed at the N-NH4 treatment was coincident with an increasing absorption of P and Mg.A influência de diferentes fontes de N sobre o crescimento de mudas de erva-mate (Ilex paraguariensis St.Hil. foi estudada, em casa de vegetação.

Full Text Available Este trabajo propone la búsqueda y exposición de patrones de formas, tanto de algunas obras producidas por la naturaleza como de algunas de las obras producidas por la mano del hombre, quien como un microcosmos, que forma parte de la naturaleza recrea el macrocosmos. En una cultura en que el hombre ha perdido contacto con la naturaleza, con sus semejantes y con sus orígenes, otro objetivo de este trabajo es re emparentar al hombre con la naturaleza de la que forma parte. Se pretende mostrar al hombre, como un fractal del Universo, que es capaz de recrear, independientemente del tiempo, del espacio y de la escala de magnitudes, las mismas formas que crea el Universo, con la fuerza de la belleza en toda su pureza y en todo lo terrible con que a veces se nos presenta su aspecto. La belleza, así como la religión o como la pureza, tiene un poder redentor y el hombre anhela los paraísos perdidos. Cuando se amplia nuestra capacidad para percibir la belleza ya estamos en camino cierto, ya estamos en un camino que nos cambia desde un estado de conciencia a otro, ya estamos en un camino de regreso a la unidad. En el presente estudio se exponen algunas formas durante la diferenciación de un platelminto, Mesocestoides corti, obtenidas mediante microscopía de barrido y se exponen algunas obras de un hombre, Francisco Brennand, ganador del premio Gabriela Mistral 1993, el mayor premio dado en artes plásticas en América. Brennand, como un holograma, con un único referencial: el Universo ha recreado un Universo biológico y de increíble belleza desde su interior. En este trabajo, se pretende además exponer como, a través de la historia de nuestra cultura, el hombre justificó el anhelo y la certeza de universalidad, generando explicaciones filosóficas, psicológicas, biológicas, físicas, matemáticas, astronómicas y artísticasThis work proposes for the search and exposition of patterns of forms as they appear in nature as well as those

60 YEARS OF NEUROENDOCRINOLOGY: MEMOIR: Harris' neuroendocrine revolution: of portal vessels and self-priming.

Science.gov (United States)

Fink, George

2015-08-01

Geoffrey Harris, while still a medical student at Cambridge, was the first researcher (1937) to provide experimental proof for the then tentative view that the anterior pituitary gland was controlled by the CNS. The elegant studies carried out by Harris in the 1940s and early 1950s, alone and in collaboration with John Green and Dora Jacobsohn, established that this control was mediated by a neurohumoral mechanism that involved the transport by hypophysial portal vessel blood of chemical substances from the hypothalamus to the anterior pituitary gland. The neurohumoral control of anterior pituitary secretion was proved by the isolation and characterisation of the 'chemical substances' (mainly neuropeptides) and the finding that these substances were released into hypophysial portal blood in a manner consistent with their physiological functions. The new discipline of neuroendocrinology - the way that the brain controls endocrine glands and vice versa - revolutionised the treatment of endocrine disorders such as growth and pubertal abnormalities, infertility and hormone-dependent tumours, and it underpins our understanding of the sexual differentiation of the brain and key aspects of behaviour and mental disorder. Neuroendocrine principles are illustrated in this Thematic Review by way of Harris' major interest: hypothalamic-pituitary-gonadal control. Attention is focussed on the measurement of GnRH in hypophysial portal blood and the role played by the self-priming effect of GnRH in promoting the onset of puberty and enabling the oestrogen-induced surge or pulses of GnRH to trigger the ovulatory gonadotrophin surge in humans and other spontaneously ovulating mammals. © 2015 Society for Endocrinology.

Pre-Alpine (Variscan) Inheritance: A Key for the Location of the Future Valaisan Basin (Western Alps)

Ballèvre, M.; Manzotti, P.; Dal Piaz, G. V.

2018-03-01

The boundary between the Helvetic and the Penninic (=Briançonnais) Zones has long been recognized as a major fault ("Penninic Front") in the Western Alps. A narrow oceanic domain has been postulated at least along part of this boundary (the Valaisan Basin). However, the information provided by the pre-Triassic basement has not been fully exploited and will be discussed here in detail. The igneous and metamorphic history of the pre-Triassic basement shows significant differences between the External Massifs from the Helvetic Zone, with abundant Late Carboniferous granites, and the basement of the Briançonnais Zone, including the Internal Massifs (Dora-Maira, Gran Paradiso, and Monte Rosa), devoid of Carboniferous granites. A major coal-bearing basin, the "Zone Houillère," opened along this boundary. This limnic intramontane basin has never been properly investigated. The Zone Houillère is not comparable with the external, paralic, flexural, basins on both sides of the Variscan belt but shows similarities with the Saar-Saale Basin. Like the latter, we interpret the Zone Houillère as a transtensional basin opened along a major, crustal-scale, fault zone, namely, the East Variscan Shear Zone. The Permian magmatism and sedimentation displays contrasting distributions, being absent or very localized in the Helvetic Zone, and widespread in the Penninic Zone. The above data indicate that the structural inheritance from the Variscan belt plays a major role in defining the future location of the Valaisan Basin, that is, the boundary between the European paleomargin and the Briançonnais microcontinent.

A groundwater flow model of the Alpine valley aquifer in the Aosta Plain (NW Italy) showed that well pumping can induce river streamflow depletions as a function of well location. Analysis of the water budget showed that ˜80% of the water pumped during 2 years by a selected well in the downstream area comes from the baseflow of the main river discharge. Alluvial aquifers hosted in Alpine valleys fall within a particular hydrogeological context where groundwater/surface-water relationships change from upstream to downstream as well as seasonally. A transient groundwater model using MODFLOW2005 and the Streamflow-Routing (SFR2) Package is here presented, aimed at investigating water exchanges between the main regional river (Dora Baltea River, a left-hand tributary of the Po River), its tributaries and the underlying shallow aquifer, which is affected by seasonal oscillations. The three-dimensional distribution of the hydraulic conductivity of the aquifer was obtained by means of a specific coding system within the database TANGRAM. Both head and flux targets were used to perform the model calibration using PEST. Results showed that the fluctuations of the water table play an important role in groundwater/surface-water interconnections. In upstream areas, groundwater is recharged by water leaking through the riverbed and the well abstraction component of the water budget changes as a function of the hydraulic conditions of the aquifer. In downstream areas, groundwater is drained by the river and most of the water pumped by wells comes from the base flow component of the river discharge.

Water solubility of synthetic pyrope at high temperature and pressure up to 12GPa

Water can be incorporated into normally anhydrous minerals as OH- defects and transported into the mantle. Its existence in the mantle may affect property of minerals, such as elasticity, electrical conductivity and rheological properties. As the secondary mineral in the mantle, garnet has not been extensively studied for its water solubility and there is discrepancies among the existing experiments on the water solubility in the garnet change at pressures and temperatures. Geiger et al., 1991 investigated water content in synthetic pyrope and concluded 0.02wt% to 0.07wt% OH- substitution. Lu et al., 1997 found 198ppm water in the Dora Miara pyrope at 100Kbar and 1000°C. Withers et al., 1998 claimed that water solubility in pyrope reached 1000ppm at 5GPa and then decreased as pressure increasing; above 7GPa, no water was detected. Mookherjee et al., 2009 also explored pyrope-rich garnet, which contains water up to 0.1%wt at 5-9GPa and temperatures 1373K-1473K. Here we report a study of water solubility of synthetic single crystal pyrope at pressures 4-12GPa and temperature 1000°C. Single crystals of pyrope were synthesized using multi-anvil press and water contents in these samples were measured using FTIR. We have observed OH- peak at 3650 cm-1 along this pressure range, although Withers, 1998 reported water contents decrease to undetectable level above 7GPa. Water solubility in pyrope will be reported as a function of pressure up to 12 GPa at 1000°C.

Endothelial cells line the lumen of the vessel wall and are exposed to flow. In linear parts of the vessel, the endothelial cells experience laminar flow, resulting in endothelial cell alignment in the direction of flow, thereby protecting the vessel wall from inflammation and permeability. In order for endothelial cells to align, they undergo rapid remodeling of the actin cytoskeleton by local activation of the small GTPase Rac1. However, it is not clear whether sustained and local activation of Rac1 is required for long-term flow-induced cell alignment. Using a FRET-based DORA Rac1 biosensor, we show that local Rac1 activity remains for 12 h upon long-term flow. Silencing studies show that the RhoGEF Trio is crucial for keeping active Rac1 at the downstream side of the cell and, as a result, for long-term flow-induced cell alignment. Surprisingly, Trio appears to be not involved in flow-induced activation of Rac1. Our data show that flow induces Rac1 activity at the downstream side of the cell in a Trio-dependent manner and that Trio functions as a scaffold protein rather than a functional GEF under long-term flow conditions. © 2017 Kroon et al.

La Construcción Social de la Identidad Femenina en el Proyecto de la Regeneración en Colombia: el Caso de Doña Bárbara Caballero y Alzate

Paola Fernández Luna

2014-01-01

Full Text Available El objetivo de este artículo es demostrar que Doña Bárbara, per - sonaje principal de la novela La Marquesa de Yolombó (1926, es una apuesta de Tomás Carrasquilla por la construcción de un personaje femenino a partir de los principios discordantes de la ideología liberal y conservadora propios del proyecto de la Regeneración. Bárbara Caba- llero y Alzate es una mujer que, a pesar de su liberalismo progresista, su intento de emancipación y su consagración a las letras, no logra concretar un proyecto autónomo. La novela es escrita en el periodo del proyecto político regenerador, en el cual se consideraba que el libe - ralismo ateo había generado una crisis axiológica que debía ser puesta en orden a través de la reconstrucción social a imagen y semejanza del orden católico. En consecuencia, se origina una oposición radical en contra de los fundamentos del liberalismo; la jerarquía conserva - dora plantea que la conducta del católico debía ser obediente tanto a la autoridad divina como a la Iglesia. En este orden de ideas, Bárbara Caballero es una metáfora del “liberalismo conservador”; en ella se hace patente el conflicto religioso y moral que vivía la sociedad colom - biana y, en particular, la mujer en el siglo XIX.

Exposure to farming environments and siblings is associated with reduced risks of childhood hay fever and atopy. We explored the independence and interaction of these protective effects in the GABRIELA study. Questionnaire surveys on farming, asthma, and allergies were conducted in four central European areas among 79,888 6-12-yr-old children. Aeroallergen-specific serum IgE was measured in a stratified sample of 8,023 children. Multiple logistic regression was used to compare gradients in allergy prevalence by sibship size across three categories of exposure to farming environments. The prevalence of hay fever ranged from 2% (95% confidence interval 1.6%; 2.7%) among farmers' children with more than two siblings to 12% (11.2%; 13.0%) among children with no farm exposure and no siblings. Farming families were larger on average. More siblings and exposure to farming environments independently conferred protection from hay fever and atopy. There was no substantial effect modification between family size and exposure to farming environments. The odds ratios for hay fever per additional sibling were 0.79 among unexposed non-farm children, 0.77 among farm-exposed non-farm children, and 0.72 among children from farming families (2df interaction test: p = 0.41). The inverse association of exposure to farming environments with hay fever is found in all sizes of family, with no substantial tendency to saturation or synergism. This suggests that different biological mechanisms may underlie these two protective factors. Combinations of a large family and exposure to farming environments markedly reduce the prevalence of hay fever and indicate the strength of its environmental determinants. © 2013 John Wiley & Sons A/S.

Full Text Available This paper is the result of the doctorate research thesis developed by the author in the School of Architecture and Urbanism of the University of São Paulo-FAUUSP, under the advisory of Prof. Silvio Soares Macedo. It aims to deep some discussions held during the oral examination by the professors Ana Gabriela Godinho Lima, Euler Sandeville, Miranda M. Magnoli and Nidia Nacib Pontuschka. The thesis focused here is called “The role of Landscape Discipline in the Education of Architects and Urbanists”. The title of this article itself is a result of the comments made by Prof. Euler Sandeville when he suggested to enhance the original thesis title, providing a more comprehensive, complex and complete idea about the landscape discipline. The reader will not found the answers to the questions posed, however he or she will be invited to reflect about the landscape discipline concepts and contempts and will be motivared to search for an identity to the universe presented here. We expect to promote a collective construction about the discipline and its roles. The thesis itself opens up the discussion about the architect and urbanist education quality, by explaining the desired ethic, by reviewing the responsabilities, the contempts and proceedings of the Landscape Design courses and by questioning their effective contribution to the Architecture and Urbanism schools in Brazil. The hypothesis being demonstrated is that the Landscape architecture disciplines are important to the profession because they enable the architect and urbanist to undertake the legal competences, established by Brazilian legislation, and allows this professional to assume the ethical commitments with the questions and problems related to the territory occupation issues, dealing with environmental resources and public spaces, in the most variable scales.

Fertilized chicken eggs were divided into the following treatment groups: placebo, diamond NPs, graphite NPs, pristine graphene, small graphene oxide, large graphene oxide, and reduced graphene oxide. Experimental solutions at a concentration of 500 µg/mL were administrated into the egg albumin. Gross pathology and the rate of survival were examined after 5, 10, 15, and 20 days of incubation. After 20 days of incubation, blood samples were collected and the weight of the body and organs measured. The relative ratio of embryo survival decreased after treatment all treatments except diamond NPs. There was no correlation between the rate of survival and the ζ-potential or the surface charge of the CNPs in solution. Body and organ weight, red blood-cell morphology, blood serum biochemical parameters, and oxidative damage in the liver did not differ among the groups. These results indicate that CNPs can remain in blood circulation without any major side effects, suggesting their potential applicability as vehicles for drug delivery or active compounds per se. However, there is a need for further investigation of their properties, which vary depending on production methods and surface functionalization.
